To the Stockholders of Vical Incorporated:

You are cordially invited to attend a special meeting of the stockholders of Vical Incorporated, a Delaware corporation, which we refer to as “we”, “Vical”, or the “company”, which will be held at 8:00 a.m., local time, on August 30, 2019, at Cooley LLP, 4401 Eastgate Mall, San Diego, California 92121, unless postponed or adjourned to a later date. This is an important meeting that affects your investment in Vical.

On June 2, 2019, Vical and Brickell Biotech, Inc. (“Brickell”) entered into an Agreement and Plan of Merger and Reorganization (the “Merger Agreement”), pursuant to which Victory Subsidiary, Inc., a wholly owned subsidiary of Vical, will merge with and into Brickell, with Brickell surviving as a wholly owned subsidiary of Vical, and Vical common stock will be issued to the former Brickell securityholders at the effective time of such merger (the “Merger”). The Merger has been unanimously approved by the boards of directors of both companies and is expected to close in the third quarter of 2019, subject to the requisite approval of Vical’s stockholders as well as the satisfaction of other conditions.

Shares of Vical common stock are currently listed on the Nasdaq Capital Market under the symbol “VICL.” Prior to consummation of the Merger, Vical intends to file an initial listing application with the Nasdaq Capital Market. After completion of the Merger, Vical will be renamed “Brickell Biotech, Inc.” and expects to trade on the Nasdaq Capital Market under the symbol “BBI.” References herein to the combined company are references to Vical following the Merger transaction.

Concurrent with the execution of the Merger Agreement, Brickell entered into a Funding Agreement (the “Funding Agreement”) with NovaQuestCo-Investment Fund X, L.P. (“NovaQuest”) pursuant to which NovaQuest committed to provide up to $25.0 million in near-term research and development funding to Brickell following the closing of the Merger (the “Concurrent Financing”), with $5.6 million of the commitment expected to be paid promptly following the closing of the Merger and the remaining portion of the commitment expected to be paid in quarterly payments equal to 67% of invoiced research and development expenses incurred during the subsequent four fiscal quarters.

In connection with the Concurrent Financing, immediately following the closing of the Merger, the combined company will issue warrants to NovaQuest (the “NovaQuest Warrants”) to purchase shares of Vical common stock. The number of shares of Vical common stock underlying the NovaQuest Warrants will be based on 10% warrant coverage on the $25.0 million NovaQuest funding commitment and the final exchange ratio for the Merger (the “Exchange Ratio”), and the exercise price of the NovaQuest Warrants will be determined based on a 10% premium to the Brickell price per share of common stock implied in the Merger, as adjusted for the Exchange Ratio.

Immediately after the effective time of the Merger, the combined company will appoint Robert Brown as its Chief Executive Officer, Andy Sklawer as itsCo-Founder, Chief Operating Officer and Secretary, Deepak Chadha as its Chief R&D Officer, R. Michael Carruthers as its Chief Financial Officer, and David McAvoy as its General Counsel. In addition, each of Dr. R. Gordon Douglas, Richard Beleson, Robert Merton, George Morrow and Thomas Shenk will resign from Vical’s board of directors effective upon the effective time of the Merger, and the designees of Brickell pursuant to the Merger Agreement, Robert Brown, Reginald Hardy, George Abercrombie, Dr. William Ju and Dennison Veru, will be appointed to fill the vacancies created by the resignations of the current Vical directors listed above. The Vical designees who will remain on the board of directors are Vijay Samant and Gary Lyons.

Vical is holding a special meeting of stockholders (the “Special Meeting”) for the following purposes, as more fully described in the accompanying proxy statement:

To consider and vote upon a proposal to approve an amendment to Vical’s restated certificate of incorporation, as amended, to effect a reverse split of Vical’s common stock (the “Reverse Split”) at a ratio in the range of between1-for-5 to1-for-15, inclusive, with such ratio to be mutually agreed by Vical and Brickell and to be effected by Vical immediately prior to the effective time of the Merger;

To consider and vote upon a proposal to approve the consummation of a change of control of Vical resulting from the Merger and the other transactions and actions contemplated by the Merger Agreement, including the Concurrent Financing and the Reverse Split (the “Contemplated Transactions”) pursuant to the rules of the Nasdaq Capital Market, as contemplated by the Merger Agreement;

To consider and vote upon a postponement or adjournment of the Special Meeting, if necessary, to solicit additional proxies if there are not sufficient votes in favor of Proposal Nos. 1 or 2 described above at the time of the Special Meeting; and

To transact any other business that may be properly brought before the meeting or any continuation, adjournment or postponement thereof.

After careful consideration, Vical’s board of directors has determined that the Contemplated Transactions set forth in and contemplated by the Merger Agreement are fair to, advisable and in the best interests of Vical and its stockholders and approved and declared advisable the Contemplated Transactions and has determined to recommend that the Vical stockholders vote to approve each of the proposals set forth in this proxy statement. Accordingly, Vical’s board of directors unanimously recommends that the Vical stockholders vote FOR each of the Proposal Nos. 1 and 2 described above; and FOR the authorization to postpone or adjourn the Special Meeting in order to permit the solicitation of additional proxies if there are not sufficient votes to approve Proposal Nos. 1 or 2 described above at the time of the Special Meeting.

QUESTIONS AND ANSWERS ABOUT THE SPECIAL MEETING AND THE MERGER

The following section provides answers to frequently asked questions about the Merger and other matters relating to the Special Meeting. This section, however, provides only summary information. For a more complete response to these questions and for additional information, please refer to the cross-referenced sections. Vical urges its stockholders to read this document in its entirety prior to making any decision.

What is the Merger?

Vical Incorporated (“Vical”), Victory Subsidiary, Inc., a wholly owned subsidiary of Vical (“Merger Sub”), and Brickell Biotech, Inc. (“Brickell”) have entered into an Agreement and Plan of Merger and Reorganization, dated as of June 2, 2019 (the “Merger Agreement”). The Merger Agreement contains the terms and conditions of the proposed merger of Vical and Brickell. Under the Merger Agreement, Merger Sub will merge with and into Brickell, with Brickell surviving as a wholly owned subsidiary of Vical (the “Merger”).

Concurrent with the execution of the Merger Agreement, Brickell entered into a Funding Agreement (the “Funding Agreement”) with NovaQuestCo-Investment Fund X, L.P. (“NovaQuest”) pursuant to which NovaQuest committed to provide up to $25.0 million in near-term research and development funding to Brickell in connection with Brickell’s sofpironium bromide product candidate following the closing of the Merger, subject to the terms and conditions of the Funding Agreement (the “Concurrent Financing”), with $5.6 million of the commitment expected to be paid promptly following the closing of the Merger and the remaining portion of the commitment expected to be paid in quarterly payments equal to 67% of invoiced research and development expenses incurred during the subsequent four fiscal quarters in connection with Brickell’s sofpironium bromide product candidate.

At the effective time of the Merger, each share of Brickell capital stock outstanding immediately prior to the effective time (excluding any (i) properly dissenting shares of Brickell common stock or (ii) shares of Brickell common stock held as treasury stock or held or owned by Brickell or Merger Sub, which will be canceled without consideration) will be automatically converted solely into the right to receive a number of shares of Vical common stock calculated using an exchange ratio formula described in the Merger Agreement (the “Exchange Ratio”). The Exchange Ratio is intended to allocate to the former Brickell securityholders and NovaQuest, collectively, approximately 60% of the aggregate number of shares of Vical common stock, and to the securityholders of Vical immediately prior to the Merger, approximately 40% of the aggregate number of shares of Vical common stock (in each case on a fully diluted basis using the treasury stock method in instances other than with respect to the NovaQuest Warrants and certain equity issuances by Brickell following the signing of the Merger Agreement and prior to the completion of the Merger). The Exchange Ratio is based on a $60.0 million valuation of Brickell and a $40.0 million valuation of Vical and is subject to adjustment based on the Vical Net Cash and Brickell Net Working Capital (each as defined in the section titled “The Merger Agreement—Conditions to the Completion of the Merger”) balances prior to the completion of the Merger.

After the completion of the Merger, Vical will change its corporate name to “Brickell Biotech, Inc.” References to the combined company in this proxy statement are references to Vical following the Merger transaction. For a more complete description of the Merger and Exchange Ratio, please see the section titled “The Merger Agreement” in this proxy statement.

What am I voting on?

There are three matters scheduled for a vote at the Special Meeting:

The approval of the amendment to Vical’s restated certificate of incorporation, as amended, to effect a reverse split of Vical’s common stock (the “Reverse Split”) at a ratio in the range of between1-for-5 to1-for-15, inclusive, with such ratio to be mutually agreed by Vical and Brickell and to be effected by Vical prior to the effective time of the Merger;

The authorization of the postponement or adjournment of the Special Meeting, if necessary, to solicit additional proxies if there are not sufficient votes in favor of Proposal Nos. 1 or 2 described above at the time of the Special Meeting.

What will happen to Vical if, for any reason, the Merger does not close?

If, for any reason, the Merger does not close, the Vical board of directors may, following the termination of the Merger Agreement, elect to, among other things, divest all or a portion of Vical’s business, or take the steps necessary to liquidate all of Vical’s business and assets. If Vical decides to dissolve and liquidate its assets, Vical would be required to pay all of its contractual obligations, and to set aside certain reserves for potential future claims, and there can be no assurance as to the amount or the timing of such a liquidation and distribution of available cash left to distribute to stockholders after paying the obligations of Vical and setting aside funds for reserves.

Why are the two companies proposing to merge?

Vical and Brickell believe that the Merger will result in a combined company that will engage in the development and potential commercialization of dermatological therapeutics, in addition to potential monetization of Vical’sVL-2397 program in the future.

Vical’s board of directors considered a number of factors that supported its decision to approve the Merger Agreement. In the course of its deliberations, Vical’s board of directors also considered a variety of risks and other countervailing factors related to entering into the Merger Agreement.

For a discussion of Vical’s reasons for the Merger, please see the section titled “The Merger—Reasons for the Merger.”

Why am I receiving these materials?

You are receiving these proxy materials because you have been identified as a stockholder of Vical as of the record date, and you are entitled to vote at the Special Meeting to approve the matters described in this proxy statement. This proxy statement contains important information about the proposed Merger, Concurrent Financing, Reverse Split and the Special Meeting and you should read it carefully and in its entirety. The enclosed voting materials allow you to authorize a proxy to vote your shares of Vical common stock without attending the Special Meeting. As promptly as practicable, please complete, sign, date and mail your proxy card in thepre-addressed postage-paid envelope provided or call the toll-free telephone number listed on your proxy card or access the Internet website described in the instructions on the enclosed proxy card.

Who can vote at the Annual Meeting?

Only stockholders of record at the close of business on July 2, 2019, will be entitled to vote at the Annual Meeting. On the record date, there were 22,841,278 shares of Vical common stock outstanding and entitled to vote.

Am I a stockholder of record?

If at the close of business on July 2, 2019, your shares were registered directly in your name with Vical’s transfer agent, Computershare, then you are a stockholder of record.

What is required to consummate the Merger?

To consummate the Merger, Proposal Nos. 1 and 2 must be approved at the Special Meeting, or at any permitted postponement or adjournment thereof, by the requisite holders of Vical common stock on the record date for the Special Meeting.

In addition to the requirement of obtaining such stockholder approval, each of the other closing conditions set forth in the Merger Agreement must be satisfied or waived.

For a more complete description of the closing conditions under the Merger Agreement, we urge you to read the section titled “The Merger Agreement—Conditions to the Completion of the Merger” in this proxy statement.

Are there any federal or state regulatory requirements that must be complied with or federal or state regulatory approvals or clearances that must be obtained in connection with the Merger?

Neither Vical nor Brickell is required to make any filings or obtain any approvals or clearances from any antitrust regulatory authorities in the United States or other countries to consummate the Merger. In the United States, Vical must comply with applicable federal and state securities laws and the rules and regulations of Nasdaq in connection with the Contemplated Transactions, and the filing with the Securities and Exchange Commission (the “SEC”) of this proxy statement. Prior to consummation of the Merger, Vical intends to file an initial listing application with Nasdaq (the “Nasdaq Listing Application”).

What will the holders of Brickell capital stock, warrants, options and convertible notes receive in the Merger?

As a result of the Merger, Brickell stockholders will become entitled to receive shares of Vical common stock in exchange for shares of Brickell capital stock in an amount to be calculated by the application of the Exchange Ratio. Each option to purchase shares of Brickell common stock that is outstanding and unexercised immediately prior to the effective time of the Merger, whether or not vested, will be converted into an option to purchase shares of Vical common stock, based on the Exchange Ratio. Each Brickell warrant that is outstanding immediately prior to the effective time of the Merger will be assumed by Vical and converted into a warrant to purchase Vical common stock, and Vical will assume each such Brickell warrant in accordance with its terms. Brickell convertible notes will convert into Brickell capital stock prior to the consummation of the Merger and holders of Brickell convertible notes will be treated like holders of Brickell capital stock following conversion. For a more complete description of what holders of Brickell capital stock, warrants, options and convertible notes will receive in the Merger, please see the sections titled “Market Price and Dividend Information” and “The Merger Agreement—Merger Consideration” in this proxy statement.

Will holders of the Vical common shares issued in the Merger and in connection with the NovaQuest Warrants be able to sell those shares without restriction?

The shares of Vical common stock issued as consideration in the Merger and in connection with the NovaQuest Warrants will be issued in transactions exempt from registration under the Securities Act of 1933, as amended (the “Securities Act”) in reliance on Section 4(a)(2) of the Securities Act, and Regulation D promulgated thereunder and may not be offered or sold by the holders of those shares absent registration or an applicable exemption from registration requirements. As a general matter, holders of such shares will not be able to transfer any of their shares until at least six months after receiving shares of Vical common stock, which is when the shares would first be eligible to be sold under Rule 144 promulgated under the Securities Act, assuming the conditions thereof are otherwise satisfied.

Certain stockholders of Brickell, including each director and executive officer of Brickell, have agreed to certain transfer restrictions on the shares of common stock to be issued to them in the Merger for a period of 180 days following the effective time of the Merger. See the section titled “Agreements Related to theMerger—Lock-Up Agreements” in this proxy statement for more detail.

Who will be the directors of the Combined Company following the Merger?

At and immediately after the effective time of the Merger, the board of directors of the combined company and its committees is expected to be comprised of the individuals set forth in the table below.

As a Vical stockholder, how does the Vical board of directors recommend that I vote?

After careful consideration, the Vical board of directors recommends that Vical stockholders vote:

•

“FOR” Proposal No. 1 to approve Vical effecting the Reverse Split;

•

“FOR” Proposal No. 2 to approve of the consummation of the change of control of Vical resulting from the Contemplated Transactions pursuant to the Nasdaq rules, as contemplated by the Merger Agreement; and

•

“FOR” Proposal No. 3 to approve of postponing or adjourning the Special Meeting, if necessary, to solicit additional proxies if there are not sufficient votes in favor of Proposal Nos. 1 or 2.

What risks should I consider in deciding whether to vote in favor of the Reverse Split and consummation of the change of control of Vical?

You should carefully review the section of this proxy statement titled “Risk Factors,” which sets forth certain risks and uncertainties related to the Merger, risks and uncertainties to which Vical, as an independent company, is subject and risks and uncertainties to which Brickell, as an independent company and the continuing company, is subject.

When do you expect the Merger to be consummated?

We anticipate that the Merger will occur as promptly as practicable after the Special Meeting to be held August 30, 2019 subject to the requisite approval of Vical’s stockholders as well as the satisfaction of other closing conditions, but we cannot predict the exact timing. For a more complete description of the closing conditions under the Merger Agreement, please see the section titled “The Merger Agreement—Conditions to the Completion of the Merger” in this proxy statement.

If effected, how will the Reverse Split affect options, restricted stock units and warrants to acquire Vical’s common stock and Vical’s stock option plans?

As of the effective time of the Reverse Split, Vical will adjust and proportionately decrease the number of shares of Vical’s common stock reserved for issuance upon exercise of, and adjust and proportionately increase the exercise price of, all options, restricted stock units and warrants to acquire Vical’s common stock at the Reverse Split ratio approved by our board of directors. All stock options, restricted stock units and warrants to acquire shares of Vical’s common stock that are outstanding immediately prior to the effective time of the Merger will remain outstanding following the effective time of the Merger. In addition, as of the effective time of the Reverse Split, Vical will adjust and proportionately decrease the total number of shares of Vical’s common stock that may be the subject of future grants under Vical’s stock plans at the selected Reverse Split ratio.

What do I need to do now?

Vical urges you to read this proxy statement carefully, including its Appendices, and to consider how the Merger affects you.

If you are a stockholder of record of Vical, you may provide your proxy instructions in one of two different ways. First, you can mail your signed proxy card in the enclosed return envelope. Second, you may also provide your proxy instructions via telephone or the Internet by following the instructions on your proxy card or instruction form. Please provide your proxy instructions only once, unless you are revoking a previously delivered proxy instruction, and as soon as possible so that your shares can be voted at the Special Meeting of Vical stockholders. The laws of the State of Delaware, under which Vical is incorporated, permit electronically transmitted proxies, provided that each such proxy contains or is submitted with information from which the inspector of elections can determine that the proxy was authorized by the stockholder.

The telephone and Internet voting procedures below are designed to authenticate stockholders’ identities, to allow stockholders to grant a proxy to vote their shares and to confirm that stockholders’ instructions have been recorded properly.

Whether you hold your shares directly as the stockholder of record or beneficially in “street name”, you may vote your shares by proxy without attending the Special Meeting. Depending on how you hold your shares, you may vote your shares in one of the following ways:

Shareholders of Record: For Shares Registered in Your Name

The procedures for voting by proxy are as follows:

•

To vote in person, come to the Special Meeting and Vical will give you a ballot when you arrive.

•

To vote by proxy on the Internet, go to http://www.proxyvote.com to complete an electronic proxy card.

•

To vote using the proxy card, simply mark, sign and date your proxy card and return it promptly in the postage-paid envelope provided.

•

To vote over the telephone, dial the toll-free phone number listed on a proxy card that may be delivered under the heading “Vote by Phone” and follow the recorded instructions.

If you vote by proxy, your vote must be received by 11:59 p.m. Eastern Time on August 29, 2019, to be counted.

We provide Internet proxy voting to allow you to vote your shares online, with procedures designed to ensure the authenticity and correctness of your proxy vote instructions. However, please be aware that you must bear any costs associated with your Internet access, such as usage charges from Internet access providers and telephone companies.

Even if you plan to attend the Special Meeting in person, we recommend that you also submit your proxy card or voting instructions or vote by telephone or via the Internet by the applicable deadline so that your vote will be counted if you later cannot attend the Special Meeting.

Beneficial Shareholders: For Shares Registered in the Name of a Broker or Bank

If your Vical shares are held by your broker as your nominee, that is, in “street name,” the enclosed voting instruction card is sent by the institution that holds your shares. Please follow the instructions included on that proxy card regarding how to instruct your broker to vote your Vical shares. If you are a beneficial owner and do not instruct your broker, bank, or other agent how to vote your shares, the question of whether your broker or nominee will still be able to vote your shares depends on whether the NYSE deems the particular proposal to be a “routine” matter. Brokers and nominees can use their discretion to vote “uninstructed” shares with respect to matters that are considered to be “routine,” but not with respect to“non-routine” matters. Under the rules and interpretations of the NYSE,“non-routine” matters are matters that may substantially affect the rights or privileges of stockholders, such as mergers, stockholder proposals, elections of directors (even if not contested), executive compensation (including any advisory stockholder votes on executive compensation and on the frequency of stockholder votes on executive compensation), and certain corporate governance proposals, even if management-supported. Proposal No. 2 (approval of the consummation of a change of control of Vical resulting from the Contemplated Transactions pursuant to the Nasdaq rules) is anon-routine matter, and accordingly your broker or nominee may not vote your shares on such proposals without your instructions. Proposal No. 1 (approval of the Reverse Split) and Proposal No. 3 (approval of the postponement or adjournment of the Special Meeting, if necessary) are considered routine matters and accordingly your broker or nominee may vote your shares on such proposals in the absence of your instructions.

Who can vote at the Special Meeting?

If, on the record date, your shares of Vical common stock are registered directly in your name with the Vical transfer agent, you are considered to be the stockholder of record with respect to those shares, and the proxy materials and proxy card are being sent directly to you by Vical. If you are a Vical stockholder of record, you may attend the Special Meeting of Vical stockholders and vote your shares in person. Even if you plan to attend the Special Meeting in person, Vical requests that you sign and return the enclosed proxy to ensure that your shares will be represented at the Special Meeting if you are unable to attend.

If, on the record date, your shares of Vical common stock are held in a brokerage account or by another nominee, you are considered the beneficial owner of shares held in “street name,” and the proxy materials are being forwarded to you by your broker or other nominee together with a voting instruction card. As the beneficial owner, you are also invited to attend the Special Meeting of Vical stockholders. Because a beneficial owner is not the stockholder of record, you may not vote these shares in person at the Special Meeting unless you obtain a proxy from the broker, trustee or nominee that holds your shares, giving you the right to vote the shares at the meeting.

How are votes counted?

Votes will be counted by the inspector of elections appointed for the meeting, who will separately count votes “For” and “Against,” abstentions and, if applicable, brokernon-votes.

What are “brokernon-votes”?

As discussed above, when a beneficial owner of shares held in “street name” does not give instructions to the broker or nominee holding the shares as to how to vote on matters deemed by the NYSE to be“non-routine,” the broker or nominee may not vote the shares. These unvoted shares are counted as “brokernon-votes.”

What is the quorum requirement?

A quorum of stockholders is necessary to hold a valid meeting. A quorum will be present if stockholders holding a majority of the issued and outstanding shares entitled to vote at a meeting are present at such meeting in person or represented by proxy. On the record date, there were 22,841,278 shares of Vical common stock outstanding and entitled to vote. Thus, the holders of 11,420,640 shares of Vical common stock must be present in person or represented by proxy at the Special Meeting to have a quorum.

Your shares will be counted towards the quorum if you submit a valid proxy (or one is submitted on your behalf by your broker, bank or other nominee) or if you vote in person at the Special Meeting. Abstentions and brokernon-votes, if applicable, will also be counted towards the quorum requirement. If there is no quorum, the holders of a majority of shares at the meeting in person or represented by proxy may postpone or adjourn the meeting to another date.

How many votes are needed to approve each proposal?

Approval of Proposal No. 1 requires the affirmative vote of the holders of a majority of the outstanding shares of Vical’s common stock outstanding as of the record date for the Special Meeting, assuming a quorum is present. Abstentions and brokernon-votes will have the effect of a “NO” vote for Proposal No. 1. It is anticipated that Proposal No. 1 will be a discretionary proposal considered routine under the rules of the NYSE.

Approval of Proposal No. 2 requires the affirmative vote of a majority of the votes cast in person or by proxy at the Special Meeting, assuming a quorum is present. Abstentions and brokernon-votes will be not be considered votes cast and will have no effect on the vote for Proposal No. 2. It is anticipated that Proposal No. 2 will be anon-discretionary proposal considerednon-routine under the rules of the NYSE.

Approval of Proposal No. 3 requires the affirmative vote of a majority of the votes present in person or by proxy at the Special Meeting and entitled to vote. Abstentions and brokernon-votes will be considered votes cast and have the effect of a “NO” vote for Proposal No. 3. It is anticipated that Proposal No. 3 will be a discretionary proposal considered routine under the rules of the NYSE.

When and where will the Special Meeting of Vical stockholders be held?

The Special Meeting of Vical stockholders will be held at 8:00 a.m., local time, on August 30, 2019 at Cooley LLP, 4401 Eastgate Mall, San Diego, California 92121. Subject to space availability, all Vical stockholders as of the record date, or their duly appointed proxies, may attend the meeting.

What if I return a proxy card or otherwise vote but do not make specific choices?

If you return a signed and dated proxy card or otherwise vote without marking voting selections, your shares will be voted, as applicable, “For” the approval of the amendment to Vical’s restated certificate of incorporation,

as amended, to effect the Reverse Split at a ratio in the range of between1-for-5 to1-for-15, inclusive, with such ratio to be mutually agreed by Vical and Brickell and to be effected by Vical prior to the effective time of the Merger (Proposal No. 1), “For” the approval of the consummation of a change of control of Vical resulting from the Contemplated Transactions pursuant to the Nasdaq rules, as contemplated by the Merger Agreement (Proposal No. 2), and “For” the authorization to postpone or adjourn the Special Meeting to solicit additional proxies if there are not sufficient votes in favor of Proposal No. 1 and Proposal No. 2 on the date of the Special Meeting.

May I change my vote after I have submitted a proxy or provided proxy instructions?

Vical stockholders of record may change their vote at any time before their proxy is voted at the Special Meeting in one of three ways. First, a stockholder of record of Vical can send a written notice to the Corporate Secretary of Vical stating that the stockholder would like to revoke its proxy. Second, a stockholder of record of Vical can submit new proxy instructions either on a new proxy card, by the telephone or via the Internet. Third, a stockholder of record of Vical can attend the Special Meeting and vote in person. Attendance alone will not revoke a proxy. If a Vical stockholder of record or a stockholder who owns Vical shares in “street name” has instructed a broker to vote its shares of Vical common stock, the stockholder must follow directions received from its broker to change those instructions.

Your most current proxy card or telephone or Internet proxy is the one that is counted.

Should Brickell’s and Vical’s stockholders send in their stock certificates now?

No. After the Merger is consummated, Brickell’s stockholders will receive written instructions from the exchange agent for exchanging their certificates representing shares of Brickell capital stock for certificates representing shares of Vical’s common stock. Each Brickell stockholder who otherwise would be entitled to receive a fractional share of Vical common stock will be entitled to receive an amount in cash, without interest, determined by multiplying such fraction by the volume-weighted average closing trading price of a share of Vical common stock on Nasdaq for the five consecutive trading days ending five trading days immediately prior to the date upon which the Merger becomes effective.

In addition, Vical’s stockholders will receive written instructions, as applicable, from Vical’s transfer agent, Computershare, for exchanging their certificates representing shares of Vical’s common stock for new certificates giving effect to the Reverse Split, if effected. Vical’s stockholders will also receive a cash payment in lieu of any fractional shares, determined by multiplying such fraction by the fair market value per share of Vical’s common stock immediately prior to the effective time of the Reverse Split as determined by the Vical board of directors.

Am I entitled to appraisal or dissenters’ rights?

No, Vical’s stockholders are not entitled to appraisal or dissenters’ rights in connection with the Merger.

Have Brickell’s stockholders agreed to adopt the Merger Agreement?

Yes. On June 2, 2019, Brickell’s stockholders adopted and approved the Merger Agreement and approved the Contemplated Transactions.

Who is paying for this proxy solicitation?

Vical pays the cost of soliciting proxies. In addition to these proxy materials, Vical’s directors and employees, and Vical’s proxy solicitor, Alliance Advisors, LLC, may also solicit proxies in person, by telephone, or by other means of communication.

The Merger(see page 64)

Under the Merger Agreement, Victory Subsidiary, Inc. (“Merger Sub”), a wholly owned subsidiary of Vical, will merge with and into Brickell, with Brickell surviving as a wholly owned subsidiary of Vical, and Vical common stock will be issued to the former Brickell stockholders at the effective time of the Merger. In connection with the closing of the Merger, Vical will change its name to “Brickell Biotech, Inc.” References to the combined company in this proxy statement are references to Vical following the Merger transaction.

10.

NovaQuest committed to provide up to $25.0 million in near-term research and development funding to Brickell in connection with sofpironium bromide following the closing of the Merger, subject to the terms and conditions of the Funding Agreement (the “Concurrent Financing”), with $5.6 million of the commitment expected to be paid promptly following the closing of the Merger and the remaining portion of the commitment expected to be paid in quarterly payments equal to 67% of invoiced research and development expenses incurred in connection with sofpironium bromide during the following four fiscal quarters.

In connection with the Concurrent Financing, immediately following the closing of the Merger, Vical is obligated to issue warrants to NovaQuest (the “NovaQuest Warrants”), to purchase shares of Vical common stock. The number of shares of Vical common stock underlying the NovaQuest Warrants will be based on 10% warrant coverage on the $25.0 million NovaQuest funding commitment and the Exchange Ratio, and the exercise price of the NovaQuest Warrants will be determined based on a 10% premium to the Brickell price per share of common stock implied in the Merger, as adjusted for the Exchange Ratio.

Vical and Brickell expect the Merger to be consummated in the third quarter of 2019, subject to receipt of the requisite approval of Vical’s stockholders, as well as the satisfaction of other conditions. Immediately following the Merger, the former Brickell securityholders and NovaQuest, collectively, are expected to own, subject to adjustment, approximately 60% of the aggregate number of shares of Vical common stock, and the securityholders of Vical as of immediately prior to the Merger are expected to own, subject to adjustment, approximately 40% of the aggregate number of shares of Vical common stock (in each case on a fully diluted basis using the treasury stock method in instances other than with respect to the NovaQuest Warrants and certain equity issuances by Brickell following the signing of the Merger Agreement and prior to the completion of the Merger).

The shares of Vical common stock to be issued in the Merger will be offered and sold in reliance on an exemption from registration under Regulation D promulgated under Section 4(a)(2) of the Securities Act. Appropriate restrictive legends will be affixed to the shares issued in the Merger.

Reasons for the Merger(see page 74)

The Vical board of directors considered various reasons to reach its conclusion that the Merger and all related transactions set forth in and contemplated by the Merger Agreement are fair to, advisable and in the best interests of Vical and its stockholders and approve and declare advisable the Merger Agreement and the Merger and the other transactions contemplated by the Merger Agreement, including a reverse split of Vical’s common stock (the “Reverse Split”) and the Concurrent Financing (collectively, the “Contemplated Transactions”).

Opinion of MTS Securities, LLC(see page 80)

Vical retained MTS Health Partners, L.P. (“MTS”) as a financial advisor in connection with the Merger. On June 2, 2019, MTS Securities, LLC (“MTS Securities”), an affiliate of MTS, rendered its oral opinion to the Vical board of directors (which was subsequently confirmed in writing as of June 2, 2019), that, as of that date and subject to the various assumptions made, procedures followed, matters considered and qualifications and limitations set forth in such written opinion and described below, the Exchange Ratio in the Merger is fair, from a financial point of view, to the holders of Vical common stock (other than Excluded Shares (as defined in “The Merger—Opinion of MTS Securities, LLC”)).

The full text of the written opinion of MTS Securities (the “MTS Opinion”) sets forth the assumptions made, procedures followed, matters considered and qualifications and limitations on the review undertaken by MTS Securities in connection with its opinion. The MTS Opinion is attached as Appendix C to this proxy statement and is incorporated herein by reference. The summary of the MTS Opinion set forth in this proxy statement is qualified in its entirety by reference to the full text of the MTS Opinion. We urge you to read carefully the MTS Opinion, together with the summary thereof in this proxy

11.

statement, in its entirety. MTS Securities provided its opinion for the information and assistance of the Vical board of directors in connection with its consideration of the Merger. The MTS Opinion addressed solely the fairness, from a financial point of view, of the Exchange Ratio, to the holders of Vical common stock in the Merger and does not address any other aspect or implication of the Merger. The MTS Opinion was not a recommendation to the Vical board of directors or any stockholder of Vical as to how to vote or to take any other action in connection with the Merger.

Overview of the Merger Agreement

Merger Consideration and Exchange Ratio(see page 95)

Brickell stockholders will receive shares of Vical common stock in exchange for shares of Brickell capital stock in an amount equal to the number of shares of Brickell capital stock held by such stockholder multiplied by the Exchange Ratio. No fractional shares of Vical common stock will be issued in connection with the Merger. Instead, each Brickell stockholder who otherwise would be entitled to receive a fractional share of Vical common stock (after aggregating all fractional shares of Vical common stock issuable to such holder) will be entitled to receive an amount in cash (rounded to the nearest whole cent), without interest, determined by multiplying such fraction by the volume-weighted average closing price of a share of Vical common stock on Nasdaq for the five trading days ending five trading days immediately prior to the date upon which the Merger becomes effective.

Immediately following the Merger, the former Brickell securityholders and NovaQuest, collectively, are expected to own, subject to adjustment, approximately 60% of the aggregate number of shares of Vical common stock, and the securityholders of Vical immediately prior to the Merger are expected to own, subject to adjustment, approximately 40% of the aggregate number of shares of Vical common stock (in each case on a fully diluted basis using the treasury stock method in instances other than with respect to the NovaQuest Warrants and certain equity issuances by Brickell following the signing of the Merger Agreement and prior to the completion of the Merger). The exchange ratio formula derived based upon the foregoing calculation is based on a $60.0 million valuation of Brickell and a $40.0 million valuation of Vical and is subject to adjustment based on the Vical Net Cash and Brickell Net Working Capital (each as defined in the section titled “The Merger Agreement—Conditions to the Completion of the Merger”) balances prior to the completion of the Merger.

For a more complete description of the Exchange Ratio, please see the section titled “The Merger Agreement—Merger Consideration and Exchange Ratio—Exchange Ratio” beginning on page 96 of this proxy statement.

Treatment of Vical Stock Options and Warrants

Treatment of Brickell Stock Options, Warrants and Convertible Notes(see page 97)

Under the terms of the Merger Agreement, each option to purchase shares of Brickell common stock that is outstanding and unexercised immediately prior to the effective time of the Merger, whether or not vested, will be converted into an option to purchase shares of Vical common stock. Vical will assume the Brickell 2019 Equity Incentive Plan and all rights with respect to each outstanding option to purchase Brickell common stock in accordance with its terms.

12.

Accordingly, from and after the effective time: (i) each outstanding Brickell option assumed by Vical may be exercised solely for shares of Vical common stock; (ii) the number of shares of Vical common stock subject to each outstanding option assumed by Vical will be determined by multiplying (A) the number of shares of Brickell common stock that were subject to such Brickell option, as in effect immediately prior to the effective time, by (B) the Exchange Ratio, and rounding the resulting number down to the nearest whole number of shares of Vical common stock; (iii) the per share exercise price for the Vical common stock issuable upon exercise of each outstanding Brickell option assumed by Vical will be determined by dividing (A) the per share exercise price of the Brickell common stock subject to such Brickell option, as in effect immediately prior to the effective time, by (B) the Exchange Ratio and rounding the resulting exercise price up to the nearest whole cent; and (iv) any restriction on the exercise of any Brickell option assumed by Vical will continue in full force and effect and the term, exercisability, vesting schedule and other provisions of such Brickell option will remain unchanged, subject to certain exceptions.

The combined company will file with the SEC, promptly after the effective time of the Merger, a registration statement on FormS-8, if available for use by the combined company, relating to the shares of Vical common stock issuable with respect to the Brickell options assumed by Vical in accordance with the Merger Agreement.

Each Brickell warrant that is outstanding immediately prior to the effective time of the Merger will be assumed by Vical and converted into a warrant to purchase Vical common stock, and Vical will assume each such Brickell warrant in accordance with its terms. All rights with respect to Brickell capital stock under the Brickell warrants assumed by Vical will be converted into rights with respect to Vical common stock. Accordingly, from and after the effective time: (i) each Brickell warrant assumed by Vical may be exercised solely for shares of Vical common stock; (ii) the number of shares of Vical common stock subject to each Brickell warrant assumed by Vical will be determined by multiplying (A) the number of shares of Brickell capital stock that were subject to such Brickell warrant, as in effect immediately prior to the effective time, by (B) the Exchange Ratio and rounding the resulting number down to the nearest whole number of shares of Vical common stock; and (iii) any restriction on any Brickell warrant assumed by Vical will continue in full force and effect and the term and other provisions of such Brickell warrant will remain unchanged.

Brickell convertible notes will convert into Brickell capital stock prior to the consummation of the Merger and the holders of such Brickell convertible notes will be treated like holders of Brickell capital stock following conversion.

Conditions to the Completion of the Merger(see page 98)

The obligations to consummate the Merger and the other transactions contemplated by the Merger Agreement shall be subject to receipt of the required Vical stockholder approvals and the satisfaction or waiver, on or prior to the effective time of the Merger, of the other conditions set forth in the section titled “The Merger Agreement—Conditions to the Completion of the Merger” below. The required Brickell stockholder approval was obtained prior to the execution of the Merger Agreement.

Non-Solicitation(see page 104)

Both Vical and Brickell are prohibited by the terms of the Merger Agreement from, directly or indirectly:

•

soliciting, initiating or knowingly encouraging, inducing or facilitating the communication, making, submission or announcement of any acquisition proposal or acquisition inquiry or taking any action that could reasonably be expected to lead to an acquisition proposal or acquisition inquiry;

Vical, however, may providenon-public information in response to a bona fide acquisition proposal made (and not withdrawn) if:

•

after consulting with outside financial advisors and outside legal counsel, Vical’s board of directors determines in good faith that such acquisition proposal constitutes, or could be reasonably likely to result in, a superior offer;

•

Vical has not breached thenon-solicit provisions of the Merger Agreement in any material respect;

•

the Vical board of directors concludes in good faith, based upon the advice of its outside legal counsel, that the failure to take such action could be reasonably likely to be inconsistent with the fiduciary duties of the board of directors under applicable law;

•

Vical receives from such person an executed confidentiality agreement containing provisions, in the aggregate, at least as favorable to Vical as those contained in the confidentiality agreement between Vical and Brickell; and

•

substantially contemporaneously with furnishing any such nonpublic information to such person, Vical furnishes such nonpublic information to Brickell.

Termination and Termination Fees(see page 110)

The Merger Agreement may be terminated by either party under certain circumstances, including, among others (and as further described in the section titled “The Merger Agreement—Termination and Termination Fees” below):

•

if a governmental body has issued a final andnon-appealable order having the effect of permanently prohibiting the Contemplated Transactions;

•

a material uncured breach by the other party of representations or certain covenants that would result in a failure of the applicable condition to the closing of the Merger; or

•

if the applicable Vical stockholder approval is not obtained at the Special Meeting.

Vical may terminate the Merger Agreement in connection with:

•

a superior offer, subject to certain conditions and payment to Brickell of a termination fee of $1.0 million.

Brickell may also terminate the Merger Agreement if at any time after the date of the Merger Agreement and prior to the closing of the Merger, the Vical Net Cash balance (as defined in the section titled “The Merger Agreement—Conditions to the Completion of the Merger”) has fallen below $30.0 million and remains below $30.0 million for more than 10 days after Vical has received notice of Brickell’s intent to terminate pursuant to the termination right described in this paragraph.

14.

Vical may also terminate the Merger Agreement, and Brickell must pay to Vical a termination fee of $1.0 million within ten business days of such termination if:

•

the Funding Agreement is terminated; or

•

(A) the conditions precedent to Brickell’s obligation to effect the Merger (other than those conditions that by their nature are to be satisfied by actions taken at the closing of the Merger) have been satisfied, (B) Vical has irrevocably confirmed by notice to Brickell that all such conditions have been satisfied as of the date of such notice (other than those conditions that by their nature are to be satisfied by actions taken at the closing of the Merger) and that it is willing to waive any other unsatisfied conditions (other than the conditions with regard to the Funding Agreement and those conditions that by their nature are to be satisfied by actions taken at the closing of the Merger) and (C) the Merger has not been consummated within three business days after the delivery of such notice.

Brickell may also terminate the Merger Agreement if (A) Vical fails to include in this proxy statement the Vical Board of Directors Recommendation or has made a Vical Board of Directors Recommendation Change (as such terms are defined in the section titled “The Merger Agreement—Vical Special Meeting”), (B) the Vical board of directors or any committee thereof publicly approves, endorses or recommends an acquisition proposal, or (C) Vical enters into any letter of intent or any contract relating to an acquisition proposal (other than a permitted confidentiality agreement). If (i) Brickell terminates the Merger Agreement pursuant to one of the events described in this paragraph, (ii) an acquisition proposal is publicly announced or disclosed to Vical or its board of directors after the date of the Merger Agreement but prior to the termination of the Merger Agreement, and (iii) within nine months after the date of such termination, Vical consummates an alternative transaction in respect of such acquisition proposal, Vical must also pay to Brickell a termination fee of $1.0 million.

Support Agreements(see page 113)

In connection with the execution of the Merger Agreement, officers, directors and certain stockholders of Brickell, who collectively beneficially owned or controlled approximately 75% of the voting power of Brickell’s outstanding capital stock onan as-converted to common stock basis as of June 2, 2019 entered into support agreements with Vical under which such stockholders agreed to, among other things, vote in favor of the adoption and approval of the Merger Agreement and the approval of the Merger and the other transactions contemplated by the Merger Agreement.

The support agreements will terminate at the earlier of the effective time of the Merger, the termination of the Merger Agreement in accordance with its terms, and written notice of termination by Vical to such stockholder.

Lock-Up Agreements(see page 113)

The officers, directors and certain other stockholders of Brickell also enteredinto lock-up agreements, pursuant to which such stockholders have agreed not to, except in limited circumstances, transfer or dispose of, any shares of Vical common stock received in the Merger or any securities convertible into, or exercisable or exchangeable for, shares of Vical common stock received in the Merger for a period of 180 days after the closing date of the Merger.

The Brickell stockholders whoexecuted lock-up agreements as of June 2, 2019 collectively beneficially owned or controlled, approximately 75% of the shares of Brickell’s outstanding capital stock onan as-converted to common stock basis.

15.

Concurrent Financing; Funding Agreement(see page 113)

Concurrent with the execution of the Merger Agreement, Brickell and NovaQuest entered into the Funding Agreement pursuant to which NovaQuest committed, subject to the terms and conditions of the Funding Agreement, to provide up to $25.0 million in near-term research and development funding to Brickell in connection with Brickell’s sofpironium bromide product candidate in the Concurrent Financing, with $5.6 million of the commitment expected to be paid promptly following the closing of the Merger and the remaining portion of the commitment expected to be paid in quarterly payments equal to 67% of invoiced research and development expenses in connection with Brickell’s sofpironium bromide product candidate incurred during the following four fiscal quarters. Upon receipt of marketing approvals in the United States for a sofpronium bromide product, Brickell will be obligated to make certain milestone payments to NovaQuest totaling $37.5 million. Beginning in the fiscal quarter that is two years following the first commercial sale of a sofpronium bromide product, Brickell will be required to make low single digit revenue sharing payments based on annual net sales worldwide (except for Japan, China and certain other countries). Generally, if Brickell suspends or terminates its development program in respect of sofpironium bromide, Brickell will be required to pay NovaQuest $25.0 million plus interest of between 8% and 12%. However, in the event that Brickell terminates its development program for sofpromium bromide for certain reasons, including serious safety issues, a failure of the product’s Phase 3 studies, or the failure of the U.S. Food and Drug Administration (“FDA”) to approve the product, Brickell will not be obligated to make any payments to NovaQuest unless it subsequently resumes the development program.

Under the Funding Agreement, Brickell makes various representations and warranties and commits to comply with various covenants. NovaQuest may terminate the Funding Agreement and terminate its obligation to make payments in the event of Brickell’s material uncured breach of a representation or covenant under the Funding Agreement. Brickell will also enter into a Security Agreement with NovaQuest immediately following consummation of the Merger. Under the Security Agreement, NovaQuest will be able to exercise certain rights in the event of an event of default of the Funding Agreement. NovaQuest’s rights following an event of default include, among other things, foreclosing on Brickell’s assets in the United States relating to Brickell’s sofpironium bromide product candidate and, in certain circumstances, accelerating payment obligations under the Funding Agreement. NovaQuest also has the right to suspend its funding obligations under the Funding Agreement in the event of certain adverse developments relating to Brickell’s sofpironium bromide product candidate and in the event that certain of our senior executives leave us and we do not find replacements acceptable to NovaQuest. These provisions of the Funding Agreement are discussed in greater detail in the section titled“Risk Factors” in this proxy statement.

In connection with the Concurrent Financing, immediately following the closing of the Merger, Vical is obligated to issue the NovaQuest Warrants to purchase shares of Vical common stock. The number of shares of Vical common stock underlying the NovaQuest Warrants will be based on 10% warrant coverage on the $25.0 million NovaQuest funding commitment and the Exchange Ratio, and the exercise price of the NovaQuest Warrants will be determined based on a 10% premium to the Brickell price per share of common stock implied in the Merger, as adjusted for the Exchange Ratio.

Regardless of whether the Merger qualifies as a reorganization within the meaning of Section 368(a) of the Code, the Merger will not result in any taxable gain or loss for U.S. federal income tax purposes to Brickell, Vical or any Vical stockholder in his, her or its capacity as a Vical stockholder.

17.

Risk Factors(see page 25)

Both Vical and Brickell are subject to various risks associated with their businesses and their industries. In addition, the Merger, including the possibility that the Merger may not be completed, poses a number of risks to each company and its respective stockholders, including the following risks:

•

If the proposed merger with Brickell is not consummated, Vical’s business could suffer materially and Vical’s stock price could decline;

•

Some of Vical’s officers and directors have conflicts of interest that may influence them to support or approve the Merger;

•

Vical’s severance agreements with Vical’s executive officers and certain other employees require Vical to pay severance benefits to any of those persons who are terminated under specified circumstances, including in connection with a change of control of Vical, which could harm Vical’s financial condition or results;

•

The Merger may be completed even though material adverse changes may result from the announcement of the Merger, industry-wide changes and other causes;

•

The market price of the combined company’s common stock may decline as a result of the Merger;

•

Vical’s stockholders may not realize a benefit from the Merger commensurate with the ownership dilution they will experience in connection with the Merger;

•

During the pendency of the Merger, Vical and Brickell will be subject to contractual limitations set forth in the Merger Agreement that restrict the parties’ ability to enter into business combination transactions with another party;

•

Because the lack of a public market for Brickell’s common stock makes it difficult to evaluate the fairness of the Merger, Brickell’s stockholders may receive consideration in the Merger that is greater than or less than the fair market value of Brickell’s common stock;

•

The Exchange Ratio is not adjustable based on the market price of Vical common stock, so the merger consideration at the closing of the Merger may have a greater or lesser value than at the time the Merger Agreement was signed;

•

The opinion received by Vical’s board of directors from MTS Securities has not been, and is not expected to be, updated to reflect changes in circumstances that may have occurred since the date of the opinion;

•

Certain stockholders could attempt to influence changes within Vical that could adversely affect Vical’s operations, financial condition and the value of Vical’s common stock;

•

Vical and Brickell may become involved in securities litigation or stockholder derivative litigation in connection with the Merger, and this could divert the attention of Vical and Brickell management and harm the combined company’s business, and insurance coverage may not be sufficient to cover all related costs and damages;

•

The Reverse Split may not increase Vical’s stock price over the long-term;

•

The Reverse Split may decrease the liquidity of Vical’s common stock;

•

The Reverse Split may lead to a decrease in Vical’s overall market capitalization; and

•

If any of the events described in “Risks Related to Brickell’s Development, Commercialization and Regulatory Approval of Brickell’s Investigational Drug, Sofpironium Bromide,” “Risks Related to Brickell’s Dependence on Third Parties,” “Risks Related to Brickell’s Business,”“Risks Related to Brickell’s Financial Operations” or “Risks Related to Brickell’s Intellectual Property” occur, those events could cause the potential benefits of the Merger not to be realized.

18.

These risks and other risks are discussed in greater detail under the section titled “Risk Factors” in this proxy statement. Vical encourages you to read and consider all of these risks carefully.

Regulatory Approvals(see page 93)

In the United States, Vical must comply with applicable federal and state securities laws and the rules and regulations of Nasdaq in connection with the issuance of shares of Vical common stock and the filing of this proxy statement with the SEC. Vical does not intend to seek any regulatory approval from antitrust authorities to consummate the transactions.

Nasdaq Capital Market Listing(see page 93)

Prior to the consummation of the Merger, Vical intends to file the Nasdaq Listing Application. If such application is accepted, Vical anticipates that Vical common stock will be listed on Nasdaq following the closing of the Merger and will trade under a new name, “Brickell Biotech, Inc.” and new trading symbol, “BBI.”

Anticipated Accounting Treatment(see page 94)

The Merger will be treated by Vical as a reverse merger recapitalization in accordance with accounting principles generally accepted in the United States. For accounting purposes, Brickell is considered to be acquiring Vical in the Merger.

Appraisal and Dissenters’ Rights(see page 94)

Vical stockholders are not entitled to appraisal rights in connection with the Merger.

Selected Unaudited Pro Forma Combined Financial Data of Vical and Brickell

The following selected unaudited pro forma combined financial data was prepared based on the historical financial results reported by Vical and Brickell and is intended to show how the Merger might have affected historical financial statements. The following should be read in conjunction with the section titled “Unaudited Pro Forma Combined Financial Statements” beginning on page 173, the Vical10-K incorporated by reference in this proxy statement, Brickell’s audited historical financial statements and the notes thereto beginning on pageF-1, the sections titled “Vical Management’s Discussion and Analysis of Financial Condition and Results of Operations” beginning on page 150 and “Management’s Discussion and Analysis of Brickell’s Financial Condition and Results of Operations” beginning on page 151 of this proxy statement, the risk factor titled “The unaudited pro forma financial information included in this proxy statement may not be representative of the combined company’s results following the Merger” on page 29, and the other information contained in this proxy statement. The following information does not give effect to the Reverse Split of Vical’s common stock described in Proposal No. 1.

The unaudited pro forma combined financial statements were prepared in accordance with the regulations of the SEC. The pro forma adjustments reflecting the completion of the Merger are based upon a reverse recapitalization in accordance with GAAP and upon the assumptions set forth in the unaudited pro forma

21.

combined financial statements. Brickell will be treated as the accounting acquirer and Vical will be treated as the acquiree for financial reporting purposes because, among other factors, immediately upon completion of the Merger, the Brickell shareholders prior to the Merger will hold a majority of the voting interest of the combined company, the seven-member board of directors of the combined company will include five of the current members of the Brickell board of directors, and therefore, members of Brickell’s current board of directors will possess five of the seven seats on the of the board of directors of the combined company and the management team will be solely comprised of members of management from Brickell.

The unaudited pro forma combined balance sheet as of June 30, 2019 is presented as if the Merger had been completed on that date. The unaudited pro forma combined statements of operations and comprehensive loss for the year ended December 31, 2018 and the six months ended June 30, 2019 combines the historical statements of operations of Vical and Brickell and gives pro forma effect to the Merger as if it had been completed on January 1, 2018.

The historical financial data has been adjusted to give pro forma effect to events that are (i) directly attributable to the Merger, (ii) factually supportable and (iii) with respect to the statements of operations, expected to have a continuing impact on the combined results. The pro forma adjustments are preliminary and based on management’s estimates of the fair value of the assets acquired and liabilities assumed, include estimates for the issuance of shares of common stock in the merger resulting from the anticipated issuance of securities by Brickell prior to the closing date of the Merger, and have been prepared to illustrate the estimated effect of the acquisition and certain other adjustments.

The unaudited pro forma combined financial data is presented for illustrative purposes only and is not necessarily indicative of the financial condition or results of operations of future periods or the financial condition or results of operations that actually would have been realized had the entities been combined during the periods presented. In addition, as explained in more detail in the accompanying notes to the unaudited pro forma combined financial statements (see the section titled “Unaudited Pro Forma Combined Financial Statements” beginning on page 173), the preliminary acquisition-date fair value of the identifiable assets acquired and liabilities assumed, and the estimated shares of common stock outstanding reflected in the unaudited pro forma combined financial statements is subject to adjustment and may vary from the actual amounts that will be recorded upon completion of the Merger.

Comparative Historical and Unaudited Pro Forma Per Share Data

The following table shows per common share data regarding basic and diluted earnings, cash dividends and book value for (a) Vical on a historical basis, (b) Brickell on a historical basis, and (c) Vical and Brickell on a pro forma combined basis.

The following pro forma information has been derived from and should be read in conjunction with Vical’s and Brickell’s respective unaudited consolidated financial statements for the six months ended June 30, 2019, which, in the case of Vical’s financial statements, are incorporated herein by reference, and in the case of Brickell’s financial statements, are included elsewhere in this proxy statement.This information is presentedfor illustrative purposes only.You should not rely on the pro forma combined amounts, as they are not necessarily indicative of the operating results or financial position that would have occurred if the Merger had been completed as of the dates indicated, nor are they necessarily indicative of the future operating results or financial position of the combined company (see risk factor titled “The unaudited pro forma financial information included in this proxy statement may not be representative of the combined company’s results following the Merger” on page 29). The pro forma information, although helpful in illustrating the financial characteristics of the combined company under one set of assumptions, does not reflect the benefits of potential cost savings, the impact of restructuring and Merger-related costs (except Merger-related costs that are reflected in the unaudited pro forma combined balance sheet included elsewhere herein), or other factors that may result as a consequence of the Merger and, accordingly, does not attempt to predict or suggest future results. The information below should be read in conjunction with the section titled “Unaudited Pro Forma Combined Financial Statements.”

MARKET PRICE AND DIVIDEND INFORMATION

Vical common stock is listed on Nasdaq under the symbol “VICL.” Brickell is a private company and its common stock and preferred stock are not publicly traded.

Vical common stock

The closing price of Vical common stock on May 31, 2019, the business day immediately prior to the public announcement of the Merger on June 3, 2019, as reported on Nasdaq, was $1.15 per share. The closing price of Vical common stock on July 11, 2019, as reported on Nasdaq, was $0.78 per share.

Because the market price of Vical common stock is subject to fluctuation, the market value of the shares of Vical common stock that Brickell stockholders will be entitled to receive in the Merger may increase or decrease.

Assuming successful application for initial listing with Nasdaq, following the consummation of the Merger, Vical common stock will continue to be listed on Nasdaq and will trade under Vical’s new name “Brickell Biotech, Inc.” and new trading symbol “BBI.”

As of July 2, 2019, the record date for the Special Meeting, Vical had 125 holders of record of its common stock.

Dividends

Vical has never declared or paid any cash dividends on its common stock and does not anticipate paying cash dividends on its common stock for the foreseeable future. Brickell has never declared or paid any cash dividends on shares of its common stock.

Brickell anticipates that the combined company will retain all of its future earnings to advance the clinical trials for its products, and does not anticipate paying any cash dividends on shares of its common stock in the foreseeable future. Any future determination to declare cash dividends on shares of the combined company’s common stock will be made at the discretion of its board of directors, subject to applicable law and contractual restrictions and will depend on its financial condition, results of operations, capital requirements, general business conditions and other factors that its board of directors may deem relevant.

24.

RISK FACTORS

The combined company will be faced with a market environment that cannot be predicted and that involves significant risks, many of which will be beyond its control. In addition to the other information contained in this proxy statement, you should carefully consider the material risks described below before deciding how to vote your shares of Vical common stock. You should also read and consider the risks associated with the business of Vical because these risks may also affect the combined company—these risks can be found in the Vical10-K and the Vical10-Q2, as filed with the SEC on March 1, 2019 and July 12, 2019, respectively, and incorporated by reference herein. You should also read and consider the other information in this proxy statement and the other documents incorporated by reference into this proxy statement. Please see the section titled “Where You Can Find More Information” on page 186 of this proxy statement.

Risks Related to the Merger

If the Merger with Brickell is not consummated, Vical’s business could suffer materially and Vical’s stock price could decline.

The consummation of the Merger with Brickell is subject to the satisfaction of a number of closing conditions, including the receipt of Vical stockholder approvals, Vical’s successful application for initial listing with Nasdaq, the occurrence of the Special Meeting, the satisfaction of the Vical Net Cash condition and other closing conditions. For a more detailed discussion of the Vical Net Cash condition and other closing conditions see the section titled “The Merger Agreement—Conditions to the Completion of the Merger.” Vical and Brickell are targeting a closing of the Merger in the third quarter of 2019.

If the Merger is not consummated, Vical may be subject to a number of material risks, and its business and stock price could be adversely affected, as follows:

•

Vical has incurred and expects to continue to incur significant expenses related to the Merger with Brickell, even if the Merger is not consummated.

•

The Merger Agreement contains covenants restricting Vical’s solicitation of competing acquisition proposals and the conduct of Vical’s business between the date of signing the Merger Agreement and the closing of the Merger. As a result, significant business decisions and transactions before the closing of the Merger require the consent of Brickell. Accordingly, Vical may be unable to pursue business opportunities that would otherwise be in its best interest as a standalone company.

•

Vical has invested significant time and resources in the transaction process and if the Merger Agreement is terminated Vical will have limited prospects, given the fact that Vical has discontinued all activities relating to development of its clinical programs, including its ASP0113 program collaboration with Astellas, its HSV-2 vaccine program and its VL-2397 Phase 2 clinical trial.

•

Vical could be obligated to pay Brickell a $1.0 million termination fee in connection with the termination of the Merger Agreement, depending on the reason for the termination.

In addition, if the Merger Agreement is terminated and Vical’s board of directors determines to seek another business combination, it may not be able to find a third party willing to provide equivalent or more attractive consideration than the consideration to be provided by each party in the Merger. Due to the lengthy nature of the strategic process, the further passage of time will diminish cash available. In such circumstances, Vical’s board of directors may elect to, among other things, divest all or a portion of Vical’s business, or take the steps necessary to liquidate all of Vical’s business and assets, and in either such case, the consideration that Vical receives may be less attractive than the consideration to be received by Vical pursuant to the Merger Agreement.

25.

Some of Vical’s officers and directors have conflicts of interest that may influence them to support or approve the Merger.

Officers and directors of Vical participate in arrangements that provide them with interests in the Merger that are different from yours, including, among others, to the extent applicable, their continued service as a director of the combined company, severance benefits and continued indemnification. These interests, among others, may influence the officers and directors of Vical to support or approve the Merger. For a more detailed discussion see “The Merger—Interests of the Vical Directors and Executive Officers in the Merger.”

Vical’s executive officers and certain other employees are parties to severance agreements that contain change of control and severance provisions providing for severance and other benefits and acceleration of vesting of stock options in the event of a termination of employment under specified circumstances. Based on the terms of their respective severance agreements, Vical’s executive officers will be entitled to receive an aggregate of approximately $2.3 million in severance benefits due to the terminations of their employment upon a change of control in connection with the consummation of the Merger. The payment of these severance benefits could harm Vical’s financial condition and results and reduce the cash available to the combined company following the Merger.

The Merger may be completed even though material adverse changes may result from the announcement of the Merger, industry-wide changes and other causes.

In general, either party can refuse to complete the Merger if there is a material adverse change affecting the other party following June 2, 2019, the date of the Merger Agreement. However, some types of changes do not permit either party to refuse to complete the Merger, even if such changes would have a material adverse effect on Vical or Brickell, to the extent they resulted from the following (unless, in some cases, they have a disproportionate effect on Vical or Brickell, as the case may be):

•

changes in the general business or economic conditions affecting the industry in which Vical and Brickell, and their respective affiliates, operate;

•

acts of war, armed hostilities or terrorism;

•

changes in financial, banking or securities markets;

•

any change in, or any compliance with or action taken for the purpose of complying with, any law or GAAP;

•

the taking of any action required to be taken by the Merger Agreement;

•

with respect to Vical, any change in the stock price or trading volume of Vical’s common stock;

•

with respect to Vical, any failure to meet analysts’ financial or industry expectations or projections; and

•

with respect to Vical, the announcement of the Merger Agreement or the pendency of the Merger.

If adverse changes occur but Vical and Brickell must still complete the Merger, the combined company’s stock price may suffer.

The market price of the combined company’s common stock may decline as a result of the Merger.

The market price of the combined company’s common stock may decline as a result of the Merger for a number of reasons, including if:

•

the combined company does not achieve the perceived benefits of the Merger as rapidly or to the extent anticipated by financial or industry analysts;

26.

•

the effect of the Merger on the combined company’s business and prospects is not consistent with the expectations of financial or industry analysts; or

•

investors react negatively to the effect on the combined company’s business and prospects from the Merger.

Vical’s stockholders may not realize a benefit from the Merger commensurate with the ownership dilution they will experience in connection with the Merger.

If the combined company is unable to realize the strategic and financial benefits currently anticipated from the Merger, Vical’s stockholders will have experienced substantial dilution of their ownership interest without receiving any commensurate benefit. Significant management attention and resources will be required to integrate the two companies. Delays in this process could adversely affect the combined company’s business, financial results, financial condition and stock price following the Merger. Even if the combined company is able to integrate the business operations successfully, there can be no assurance that this integration will result in the realization of the full benefits of synergies, innovation and operational efficiencies that may be possible from this integration and that these benefits will be achieved within a reasonable period of time.

The combined company will incur significant transaction costs as a result of the Merger, including investment banking, legal and accounting fees. In addition, the combined company will incur significant consolidation and integration expenses which cannot be accurately estimated at this time. Actual transaction costs may substantially exceed estimates and may have an adverse effect on the combined company’s financial condition and operating results.

Covenants in the Merger Agreement impede the ability of Vical or Brickell to make acquisitions or complete other transactions that are not in the ordinary course of business pending completion of the Merger. As a result, if the Merger is not completed, the parties may be at a disadvantage to their competitors. In addition, while the Merger Agreement is in effect and subject to limited exceptions, each party is prohibited from soliciting, initiating, encouraging or taking actions designed to facilitate any inquiries or the making of any proposal or offer that could lead to the entering into certain extraordinary transactions with any third party, such as a sale of assets, an acquisition of Vical’s common stock, a tender offer for Vical’s common stock, a Merger or other business combination outside the ordinary course of business. Any such transactions could be favorable to such party’s stockholders.

The outstanding share capital of Brickell is privately held and is not traded in any public market. The lack of a public market makes it difficult to determine the fair market value of Brickell. It is possible that the value of Vical’s common stock to be issued in connection with the Merger will be greater than the fair market value of Brickell.

Because the Merger will result in an ownership change under Section 382 of the Internal Revenue Code (the “Code”) for Vical, Vical’spre-merger net operating loss carryforwards and certain other tax attributes will be subject to limitations. The net operating loss carryforwards and other tax attributes of Brickell and of the combined organization may also be subject to limitations as a result of ownership changes.

If a corporation undergoes an “ownership change” within the meaning of Section 382 of the Code (“Section 382”), the corporation’s net operating loss carryforwards and certain other tax attributes arising before

27.

the ownership change are subject to limitations on use after the ownership change. In general, an ownership change occurs if there is a cumulative change in the corporation’s equity ownership by certain stockholders that exceeds fifty percentage points over a rolling three-year period. Similar rules may apply under state tax laws. The Merger will result in an ownership change for Vical and, accordingly, Vical’s net operating loss carryforwards and certain other tax attributes will be subject to limitations (or disallowance) on their use after the Merger. Brickell’s net operating loss carryforwards may also be subject to limitation as a result of prior shifts in equity ownership and/or the Merger. Additional ownership changes in the future could result in additional limitations on Vical’s, Brickell’s and the combined organization’s net operating loss carryforwards. Consequently, even if the combined organization achieves profitability, it may not be able to utilize a material portion of Vical’s, Brickell’s or the combined organization’s net operating loss carryforwards and other tax attributes, which could have a material adverse effect on cash flow and results of operations.

The Exchange Ratio is not adjustable based on the market price of Vical common stock so the merger consideration at the closing of the Merger may have a greater or lesser value than at the time the Merger Agreement was signed.

At the effective time of the Merger, outstanding shares of Brickell capital stock will be converted into shares of Vical common stock. Applying the Exchange Ratio, the former Brickell securityholders and NovaQuest, collectively, are expected to own, subject to adjustment, approximately 60% of the aggregate number of shares of Vical common stock, and the securityholders of Vical as of immediately prior to the Merger are expected to own, subject to adjustment, approximately 40% of the aggregate number of shares of Vical common stock (in each case on a fully diluted basis using the treasury stock method in instances other than with respect to the NovaQuest Warrants and certain equity issuances by Brickell following the signing of the Merger Agreement and prior to the completion of the Merger). The exchange ratio formula is based on a $60.0 million valuation of Brickell and a $40.0 million valuation of Vical and is subject to adjustment based on the Vical Net Cash and Brickell Net Working Capital balances (each as defined in the section titled “The Merger Agreement—Conditions to the Completion of the Merger”) prior to the completion of the Merger.

Any changes in the market price of Vical common stock before the completion of the Merger will not affect the number of shares Brickell stockholders will be entitled to receive pursuant to the Merger Agreement. Therefore, if before the completion of the Merger the market price of Vical common stock declines from the market price on the date of the Merger Agreement, then Brickell securityholders could receive merger consideration with substantially lower value. Similarly, if before the completion of the Merger the market price of Vical common stock increases from the market price on the date of the Merger Agreement, then Brickell securityholders could receive merger consideration with substantially more value for their shares of Brickell capital stock than the parties had negotiated for in the establishment of the Exchange Ratio. The Merger Agreement does not include a price-based termination right. Because the Exchange Ratio does not adjust as a result of changes in the value of Vical common stock, for each one percentage point that the market value of Vical common stock rises or declines, there is a corresponding one percentage point rise or decline, respectively, in the value of the total merger consideration issued to Brickell securityholders.

Vical retained MTS as a financial advisor in connection with the Merger. On June 2, 2019, MTS Securities, an affiliate of MTS, delivered its opinion to the board of directors of Vical that, as of June 2, 2019, and subject to the various assumptions made, procedures followed, matters considered and qualifications and limitations set forth in such written opinion, the Exchange Ratio is fair, from a financial point of view, to the holders of Vical common stock (other than Excluded Shares (as defined in “The Merger—Opinion of MTS Securities, LLC”). The opinion addresses solely the fairness, from a financial point of view and as of the date of such opinion, of the Exchange Ratio to the holders of Vical common stock and does not address any other terms in the Merger Agreement, or any other agreement contemplated by the Merger Agreement or relating to the Merger or any

28.

other aspect or implication of the Merger, including, without limitation, the form or structure of the Merger or the fairness of the Merger or the Exchange Ratio to any other securityholders or creditors or any other constituency of Vical. MTS Securities did not consider any potential legislative or regulatory changes currently being considered by the SEC, or any other governmental or regulatory bodies, or any changes in accounting methods or generally accepted accounting principles that may be adopted by the SEC or the Financial Accounting Standards Board. It should be understood that, although subsequent developments may affect the conclusion reached in the opinion, MTS Securities does not have any obligation to update, revise or reaffirm such opinion and has not done so. See the section titled “The Merger—Opinion of MTS Securities, LLC” and Appendix B to this proxy statement.

Securities litigation or stockholder derivative litigation frequently follows the announcement of certain significant business transactions, such as the sale of a business division or announcement of a business combination transaction. Vical and Brickell may become involved in this type of litigation in connection with the Merger, and the combined company may become involved in this type of litigation in the future. Litigation often is expensive and diverts management’s attention and resources, which could adversely affect the business of Vical, Brickell and the combined company, and insurance coverage may not be sufficient to cover all related costs and damages.

If any of the events described in “Risks Related to Brickell’s Development, Commercialization and Regulatory Approval of Brickell’s Investigational Drug, Sofpironium Bromide,” “Risks Related to Brickell’s Dependence on Third Parties” “Risks Related to Brickell’s Business,” “Risks Related to Brickell’s Financial Operations” or “Risks Related to Brickell’s Intellectual Property” occur, those events could cause the potential benefits of the Merger not to be realized.

Brickell’s business is expected to constitute substantially all of the business of the combined company following the Merger. As a result, the risks described below in the sections titled “Risks Related to Brickell’s Development, Commercialization and Regulatory Approval of Brickell’s Investigational Drug, Sofpironium Bromide” beginning on page 33, “Risks Related to Brickell’s Dependence on Third Parties” beginning on page 47, “Risks Related to Brickell’s Business” beginning on page 40,“Risks Related to Brickell’s Financial Operations” beginning on page 50 and “Risks Related to Brickell’s Intellectual Property” beginning on page 54 are among the most significant risks to the combined company if the Merger is completed. To the extent any of the events in the risks described in the sections referenced in the previous sentence occur, those events could cause the potential benefits of the Merger not to be realized and the market price of the combined company’s common stock to decline.

The unaudited pro forma financial information included in this proxy statement may not be representative of the combined company’s results following the Merger.

The unaudited pro forma financial information included in this proxy statement has been presented for informational purposes only and is not necessarily indicative of the financial position or results of operations that actually would have occurred had the Merger and related transactions been completed as of the date indicated, nor is it indicative of the combined company’s future operating results or financial position. The pro forma financial statements have been derived from the historical financial statements of Vical and Brickell and adjustments and assumptions have been made regarding the combined company after giving effect to the Merger. The information upon which these adjustments and assumptions have been made is preliminary, and these kinds of adjustments and assumptions are difficult to make with accuracy. Moreover, the pro forma financial statements do not reflect all costs that are expected to be incurred by the combined company in connection with

29.

the Merger. As a result, the actual financial condition of the combined company following the Merger may not be consistent with, or evident from, these pro forma financial statements. The assumptions used in preparing the pro forma financial information may not prove to be accurate, and other factors may affect the combined company’s financial condition following the Merger and related transactions.

Risks Related to the Proposed Reverse Split

The Reverse Split may not increase the combined company’s stock price over the long-term.

The principal purpose of the Reverse Split is to increase theper-share market price of the combined company’s common stock above the minimum bid price requirement under the Nasdaq rules so that the listing of the combined company and the shares of the combined company common stock being issued in the Merger on Nasdaq will be approved. It cannot be assured, however, that the Reverse Split will accomplish this objective for any meaningful period of time. While it is expected that the reduction in the number of outstanding shares of common stock will proportionally increase the market price of the combined company’s common stock, it cannot be assured that the Reverse Split will increase the market price of its common stock by a multiple of the reverse stock split ratio mutually agreed by Brickell and Vical, or result in any permanent or sustained increase in the market price of the combined company’s common stock, which is dependent upon many factors, including the combined company’s business and financial performance, general market conditions, and prospects for future success. Thus, while the stock price of the combined company might meet the continued listing requirements for Nasdaq initially, it cannot be assured that it will continue to do so.

The Reverse Split may decrease the liquidity of the combined company’s common stock.

Although Vical’s board of directors believes that the anticipated increase in the market price of the combined company’s common stock could encourage interest in its common stock and possibly promote greater liquidity for its stockholders, such liquidity could also be adversely affected by the reduced number of shares outstanding after the Reverse Split. The reduction in the number of outstanding shares may lead to reduced trading and a smaller number of market makers for the combined company’s common stock.

The Reverse Split may lead to a decrease in the combined company’s overall market capitalization.

Should the market price of the combined company’s common stock decline after the Reverse Split, the percentage decline may be greater, due to the smaller number of shares outstanding, than it would have been prior to the Reverse Split. A reverse stock split is often viewed negatively by the market and, consequently, can lead to a decrease in the combined company’s overall market capitalization. If the per share market price does not increase in proportion to the reverse stock split ratio, then the value of the combined company, as measured by its stock capitalization, will be reduced. In some cases, theper-share stock price of companies that have effected reverse stock splits subsequently declined back topre-reverse split levels, and accordingly, it cannot be assured that the total market value of the combined company’s common stock will remain the same after the Reverse Split is effected, or that the Reverse Split will not have an adverse effect on the combined company’s stock price due to the reduced number of shares outstanding after the Reverse Split.

Risks Related to Vical

For risks related to the business of Vical, please refer to the section titled “Item 1A. Risk Factors” set forth in the Vical 10-K, as filed with the SEC on March 1, 2019, which report is incorporated by reference herein.

Risks Related to Vical’s Common Stock

The price of Vical’s common stock has been and may continue to be volatile.

The stock markets in general, the markets for biotechnology stocks and, in particular, the stock price of Vical’s common stock, have experienced extreme volatility. The market for Vical’s common stock is

30.

characterized by significant price volatility when compared to the shares of larger, more established companies that trade on a national securities exchange and have large public floats, and Vical expects that its share price will continue to be more volatile than the shares of such larger, more established companies for the indefinite future. The volatility in Vical’s stock price is attributable to a number of factors. Vical’s common stock are, compared to the shares of such larger, more established companies, infrequently and thinly traded. As a consequence of this limited liquidity, the trading of relatively small quantities of shares by Vical’s stockholders may disproportionately influence the price of those shares in either direction. The price for Vical’s stock could, for example, decline precipitously in the event that a large number of shares of its common stock are sold on the market without commensurate demand. Vical’s common stock is also a speculative or “risky” investment due to the status of its drug development programs and Vical’s lack of profits to date, and uncertainty of future market acceptance for its potential products and its ability to continue as a going concern. As a consequence of this enhanced risk, more risk-adverse investors may, under the fear of losing all or most of their investment in the event of negative news or lack of progress, be more inclined to sell their shares on the market more quickly and at greater discounts than would be the case with the stock of a larger, more established company that has a large public float and broader stockholder base. Many of these factors are beyond Vical’s control and may decrease the market price of Vical’s common stock, regardless of Vical’s operating performance. Vical cannot make any predictions or projections as to what the prevailing market price for its common shares will be at any time, including as to whether its common stock will sustain their current market prices, or as to what effect that the sale of shares or the availability of common stock for sale at any time will have on the prevailing market price.

In the past, following periods of volatility in the market price of a particular company’s securities, litigation has often been brought against that company. Any such lawsuit could consume resources and management time and attention, which could adversely affect Vical’s business.

Provisions of Delaware law and Vical’s current certificate of incorporation and bylaws may discourage another company from acquiring it and may prevent attempts by Vical’s stockholders to replace or remove Vical’s current management.

Provisions of Delaware law and Vical’s current certificate of incorporation and bylaws may discourage, delay or prevent a Merger or acquisition that stockholders may consider favorable, including transactions in which you might otherwise receive a premium for your shares. In addition, these provisions may frustrate or prevent any attempts by Vical’s stockholders to replace or remove Vical’s current management by making it more difficult for stockholders to replace or remove Vical’s board of directors. These provisions include:

•

authorizing the issuance of “blank check” preferred stock without any need for action by stockholders;

•

providing for a classified board of directors with staggered terms;

•

requiring supermajority stockholder voting to effect certain amendments to Vical’s restated certificate of incorporation and bylaws;

•

eliminating the ability of stockholders to call special meetings of stockholders;

•

prohibiting stockholder action by written consent; and

•

establishing advance notice requirements for nominations for election to Vical’s board of directors or for proposing matters that can be acted on by stockholders at stockholder meetings.

Although Vical believes these provisions collectively provide for an opportunity to receive higher bids by requiring potential acquirers to negotiate with Vical’s board of directors, they would apply even if an offer may be considered beneficial by some stockholders. In addition, these provisions may frustrate or prevent any attempts by Vical’s stockholders to replace or remove Vical’s current management by making it difficult for stockholders to replace members of Vical’s board of directors, which is responsible for appointing the members of Vical’s management.

31.

If the holders of Brickell’s options, warrants and convertible notes exercise their rights to acquire stock of the combined company, the ownership of the stockholders of the combined company will be diluted.

As of the date of this proxy statement, Brickell has issued $5.9 million in convertible notes and related warrants at 50% coverage, to acquire approximately 1,177,389 shares of common stock (based on the estimated price per share of Brickell common stock implied in the Merger), and has 1,811,800 options issued and outstanding. In addition, upon closing of the Funding Agreement, Vical will issue warrants to NovaQuest (the “NovaQuest Warrants”) to purchase shares of Vical common stock. The number of shares of common stock underlying the NovaQuest Warrants will be based on 10% warrant coverage on the $25.0 million NovaQuest funding commitment and the Exchange Ratio, and the exercise price of the NovaQuest Warrants will be determined based on a 10% premium to the Brickell price per share of common stock implied in the Merger, as adjusted for the Exchange Ratio. In total, Brickell intends to issue up to $12.5 million in convertible notes, and related warrants at 50% coverage, to acquire 2,493,665 shares of Brickell common stock (based on the estimated price per share of Brickell common stock implied in the Merger), as well as options to acquire up to 2,607,274 shares of Brickell common stock, prior to consummation of the Merger. If the holders of options, warrants (including NovaQuest) and convertible notes exercise their rights to acquire stock of the combined company, the percentage ownership of the combined company’s stockholders existing prior to the exercise of rights will be diluted.

Risks Related to Vical Management Brickell Projections

You should be aware that uncertainties are inherent in prospective financial projections of any kind, and such uncertainties increase with the passage of time. None of Brickell or Vical or any of their respective affiliates, advisors, officers, directors, or representatives has made or makes any representation or can give any assurance to any Vical stockholders, or any other person, regarding the ultimate performance of Brickell compared to the information set forth in the section titled “Certain Vical Management Unaudited Prospective Financial Information” or that any such results will be achieved.

The inclusion of the Vical management Brickell projections in this proxy statement should not be regarded as an indication that Vical, Brickell or their respective advisors or other representatives considered or consider the projections to be necessarily predictive of actual future performance or events, and the Vical management Brickell projections set forth in the section titled “Certain Vical Management Unaudited Prospective Financial Information” should not be relied upon as such.

The Vical management Brickell projections were prepared by management of Vical based, in part, on certain information furnished by Brickell. The prospective financial information was not prepared with a view toward public disclosure nor was it prepared with a view toward compliance with the guidelines established by GAAP. Neither the independent registered public accounting firm of Vical, Brickell nor any other independent accounts has audited, reviewed, compiled, examined or performed any procedures with respect to the accompanying unaudited prospective financial information for the purpose of its inclusion herein, and accordingly, neither the independent registered public accounting firm of Vical, Brickell, nor any other independent accountant expresses an opinion or provides any form of assurance with respect thereto for the purpose of this proxy statement. Due to inherent uncertainties in financial projections of any kind, stockholders are cautioned not to place undue reliance, if any, on the Vical management Brickell projections.

Vical management Brickell projections are subjective in nature and may not be realized.

The Vical management Brickell projections are inherently subjective in nature and susceptible to interpretation and, accordingly, such projections may not be achieved. The Vical management Brickell projections also reflect numerous assumptions made by management, including material assumptions regarding, among other things, timing of Phase 3 clinical trials, timing of receipt of regulatory approvals, as to which there can be no assurance, market size, commercial efforts, and numerous other matters that may not be realized and are subject to significant uncertainties and contingencies, all of which are difficult to predict and many of which are beyond the control of the preparing party. Accordingly, there can be no assurance that the assumptions made

32.

in preparing the Vical management Brickell projections upon which the projected financial information was based will be realized. There may be differences between actual and projected results, and the differences may be material. The risk that these uncertainties and contingencies could cause the assumptions to fail to be reflective of actual results is further increased by the length of time over which these assumptions apply. The failure to achieve assumptions and projections in early periods could have a compounding effect on the projections shown for the later periods. Thus, any such failure of an assumption or projection to be reflective of actual results in an early period could have a greater effect on the projected results failing to be reflective of actual events in later periods. Brickell is a clinical stage company, without a U.S. Food and Drug Administration (“FDA”) approved product, and as discussed in this proxy statement, its business is subject to numerous risks. Moreover,15-year projections in the context of a clinical stage company are inherently unreliable given the many variables, especially in later years, that may affect results.

All of these assumptions involve variables making them difficult to predict, and some are beyond the control of Brickell and Vical. Although Vical’s management believes that there was a reasonable basis for its projections and underlying assumptions, any assumptions for near-term projected cases remain uncertain, and such uncertainty increases with the length of the projected period. The projections are forward-looking statements and are subject to risks and uncertainties. See the section titled “Cautionary Note Concerning Forward-Looking Statements” on page 59. For a discussion of the Vical management Brickell projections, please see the section titled “Certain Vical Management Unaudited Prospective Financial Information” beginning on page 77.

In developing the Vical management Brickell projections provided to the Vical board, Vical management made numerous material estimates with respect to Brickell for the years ending December 31, 2019 through 2034.

The Vical management Brickell projections prepared by Vical management were based on estimates from both discussions with, and materials provided, by Brickell for the years from 2019 to 2025, which themselves were based on numerous assumptions. Additionally, such estimates were then used by Vical to extrapolate certain prospective financial results based on Vical management’s assessment of comparable companies and industry metrics (except that the unadjusted projections in respect of sofpirinium bromide milestone and royalty payments were provided by Brickell’s management and were based on Brickell’s management’s estimates for each of the calendar years ending December 31, 2019 through 2033). Vical management did not consider ranges for various financial measures but rather considered in deriving these measures, peak sales amounts, which may reduce the utility in later years of the prospective financial results.

Risks Related to Brickell

Risks Related to Brickell’s Development, Commercialization and Regulatory Approval of Brickell’s Investigational Drug, Sofpironium Bromide

Brickell’s business depends on the successful clinical development, regulatory approval and commercialization of sofpironium bromide.

The success of Brickell’s business, including its ability to finance itself and generate revenue in the future, primarily depends on the successful development, regulatory approval and commercialization of sofpironium bromide. The clinical and commercial success of sofpironium bromide depends on a number of factors, including the following:

•

timely and successful completion of Phase 3 clinical trials not yet initiated, which may be significantly slower or costlier than Brickell currently anticipates and/or produce results that do not achieve the endpoints of the trials;

•

whether Brickell is required by the FDA or similar foreign regulatory agencies to conduct additional clinical trials beyond those planned to support the approval and commercialization of sofpironium bromide;

33.

•

achieving and maintaining, and, where applicable, ensuring that Brickell’s third-party contractors achieve and maintain, compliance with their contractual obligations and with all regulatory requirements applicable to sofpironium bromide;

•

ability of third parties with whom Brickell contracts to manufacture adequate clinical trial and commercial supplies of sofpironium bromide, to remain in good standing with regulatory agencies and to develop, validate and maintain commercially viable manufacturing processes that are compliant with current good manufacturing practices (“cGMP”);

•

a continued acceptable safety profile during clinical development and following approval of sofpironium bromide;

•

ability to obtain favorable labeling for sofpironium bromide through regulators that allows for successful commercialization, given the drug may be marketed only to the extent approved by these regulatory authorities (unlike with most other industries);

•

ability to successfully commercialize sofpironium bromide in the United States and internationally, if approved for marketing, sale and distribution in such countries and territories, whether alone or in collaboration with Kaken Pharmaceutical Co. Ltd. (“Kaken”) or others;

•

acceptance by physicians, insurers and payors, and patients of the quality, benefits, safety and efficacy of sofpironium bromide, if approved, including relative to alternative and competing treatments;

•

existence of a regulatory environment conducive to the success of sofpironium bromide;

•

ability to price sofpironium bromide to recover Brickell’s development costs and generate a satisfactory profit margin; and

•

Brickell’s ability and its partners’ ability to establish and enforce intellectual property rights in and to sofpironium bromide.

If Brickell does not achieve one or more of these factors, many of which are beyond its control, in a timely manner or at all, Brickell could experience significant delays or an inability to obtain regulatory approvals or commercialize sofpironium bromide. Even if regulatory approvals are obtained, Brickell may never be able to successfully commercialize sofpironium bromide. Accordingly, Brickell cannot assure you that it will be able to generate sufficient revenue through the sale of sofpironium bromide to continue its business.

Brickell has never conducted a Phase 3 clinical trial itself and may be unable to successfully do so for sofpironium bromide.

The conduct of a Phase 3 clinical trial is a long, expensive, complicated and highly regulated process. Although Brickell’s employees have conducted successful Phase 2 and Phase 3 clinical trials in the past across many therapeutic areas while employed at other companies, Brickell as a company has not conducted a Phase 3 pivotal clinical trial, and as a result may require more time and incur greater costs than it anticipates. Brickell commenced a Phase 3 long-term safety study for sofpironium bromide gel in the third quarter of 2018 and intends to initiate Phase 3 pivotal clinical trials for the registration of sofpironium bromide gel in the second half of 2019 for the U.S. market, as more fully described in “Description of Brickell’s Business.” Failure to commence or complete, or delays in, Brickell’s planned clinical trials would prevent it from or delay Brickell in obtaining regulatory approval of and commercializing sofpironium bromide and could prevent it from or delay it in receiving development- or regulatory-based milestone payments and commercializing sofpironium bromide gel for the treatment of hyperhidrosis, which would adversely impact its financial performance, as well as put Brickell in potential breach of material contracts for the development of sofpironium bromide subjecting it to significant contract liabilities.

Clinical drug development for sofpironium bromide is very expensive, time-consuming and uncertain.

Clinical development for sofpironium bromide is very expensive, time-consuming, difficult to design and implement, and its outcome is inherently uncertain. Most product candidates that commence clinical trials are

34.

never approved by regulatory authorities for commercialization and of those that are approved many do not cover their costs of development. In addition, Brickell, any partner with which it currently or may in the future collaborate, the FDA, an institutional review board (“IRB”), or other regulatory authorities, including state and local agencies and counterpart agencies in foreign countries, may suspend, delay, require modifications to or terminate Brickell’s clinical trials at any time.

In the case of sofpironium bromide, Brickell is seeking to deliver sufficient concentrations of the active pharmaceutical ingredient (“API”) absorbed from the skin surface through the skin barrier to the targeted dermal tissue to achieve the intended therapeutic effect. The topical route of administration may involve new dosage forms, which can be difficult to develop and manufacture and may raise novel regulatory issues and result in development or review delays.

Use of patient-reported outcome assessments (“PROs”) in sofpironium bromide clinical trials may delay the development of sofpironium bromide gel or increase Brickell’s development costs.

Due to the difficulty of objectively measuring the symptoms of hyperhidrosis, which is the primary target of treatment for sofpironium bromide, PROs will have an important role in the development and regulatory approval of sofpironium bromide. PROs involve patients’ own subjective assessments of efficacy, and this subjectivity increases the uncertainty of determining and achieving clinical endpoints. Such assessments can be influenced by factors outside of Brickell’s reasonable control, and can vary widely from day to day for a particular patient, and from patient to patient and site to site within a clinical trial.

Sofpironium bromide may cause undesirable side effects or have other unexpected properties that could delay or prevent its regulatory approval, limit the commercial profile of an approved label, or result in post-approval regulatory action.

Unforeseen side effects from sofpironium bromide could arise either during clinical development or, if approved, after it has been marketed. Undesirable side effects caused by sofpironium bromide could cause Brickell, any partners with which Brickell may collaborate, or regulatory authorities to interrupt, extend, modify, delay or halt clinical trials and could result in a more restrictive or narrower label or the delay or denial of regulatory approval by the FDA or comparable foreign authorities.

Results of clinical trials could reveal a high and unacceptable severity and prevalence of side effects. In such an event, trials could be suspended or terminated and the FDA or comparable foreign regulatory authorities could order us to cease further development of or deny approval of sofpironium bromide for any or all targeted indications. The drug-related side effects could affect patient recruitment or the ability of enrolled patients to complete the trial or result in product liability claims. Any of these occurrences may harm Brickell’s business, financial condition, operating results and prospects.

Additionally, if Brickell or others identify undesirable side effects, or other previously unknown problems, caused by sofpironium bromide after obtaining U.S. or foreign regulatory approval, a number of potentially negative consequences could result, which could prevent Brickell or its potential partners from achieving or maintaining market acceptance of sofpironium bromide and could substantially increase the costs of commercializing sofpironium bromide.

Kaken substantially controls the development of sofpironium bromide in Japan and certain other Asian countries and may make decisions regarding product development, regulatory strategy and commercialization that may not be in Brickell’s best interests. Kaken may be unable to obtain positive approval of the drug in Asian markets.

In March 2015, Brickell entered into a license agreement with Kaken. The agreement granted Kaken an exclusive Japan license and certain rights to additional Asian countries to develop and commercialize sofpironium bromide. Under the terms of the agreement, Brickell received anup-front payment and is eligible to receive future development and sales milestones and a royalty on net sales.

35.

Kaken has final decision-making authority for the overall regulatory, development and commercialization strategy for sofpironium bromide, market access activities, pricing and reimbursement activities, promotion, distribution, packaging, sales and safety and pharmacovigilance in Japan and certain other Asian countries. In exercising its final decision-making authority in such territories, Kaken may make decisions regarding product development or regulatory strategy based on its determination of how best to preserve and extend regulatory approvals in these territories for sofpironium bromide, which may delay or prevent achieving regulatory approval for sofpironium bromide in Kaken’s territories, as well as in the United States and the other territories which Brickell maintains exclusive rights. Additionally, Kaken is responsible for conducting certain nonclinical and chemistry, manufacturing and controls-related activities that also will be required for FDA approval in the United States, and as a result, Brickell is reliant on Kaken to execute successfully, in a timely and efficient manner, such activities on Brickell’s behalf. To the extent Kaken experiences delays and/or difficulties in performing its development activities, this could prevent or cause substantial delays in Brickell’s ability to seek approval for sofpironium bromide gel in the United States and other territories in which Brickell maintains exclusive rights. Brickell will not receive additional milestone or other payments from Kaken if Kaken is not successful in its development activities.

If Brickell or any partners with which Brickell may collaborate are unable to achieve and maintain coverage and adequate levels of reimbursement for sofpironium bromide following regulatory approval, its commercial success may be hindered severely.

If sofpironium bromide only becomes available by prescription, successful sales by Brickell or by any partners with which Brickell may collaborate depend on the availability of coverage and adequate reimbursement from third-party payors. Patients who are prescribed medicine for the treatment of their conditions generally rely on third-party payors to reimburse all or part of the costs associated with their prescription drugs. The availability of coverage and adequate reimbursement from governmental healthcare programs, such as Medicare and Medicaid in the United States, and private third-party payors is often critical to new product acceptance. Coverage decisions may depend on clinical and economic standards that disfavor new drug products when more established or lower-cost therapeutic alternatives are already available or subsequently become available, or may be affected by the budgets and demands on the various entities responsible for providing health insurance to patients who will use sofpironium bromide. If insurers and payors decide that hyperhidrosis itself is not a disease they are willing to extend coverage to, which could happen if they only think the treatment improves quality of life, then coverage and reimbursement for sofpironium bromide may be denied. In this case, patients would be forced to pay for sofpironium bromideout-of-pocket for cash, which they may not be willing to do. Even if Brickell obtains coverage for sofpironium bromide, the resulting reimbursement payment rates might not be adequate or may requireco-payments that patients find unacceptably high. Patients are unlikely to use sofpironium bromide unless coverage is provided and reimbursement is adequate to cover a significant portion of the cost of sofpironium bromide.

In addition, the market for sofpironium bromide will depend significantly on access to third-party payors’ drug formularies, or lists of medications for which third-party payors provide coverage and reimbursement. The industry competition to be included in such formularies often leads to downward pricing pressures on pharmaceutical companies and there may be time limitations on when a new drug may even apply for formulary inclusion. Also, third-party payors may refuse to include sofpironium bromide in their formularies or otherwise restrict patient access to sofpironium bromide when a less costly generic equivalent or other treatment alternative is available in the discretion of the formulary.

Third-party payors, whether foreign or domestic, or governmental or commercial, are developing increasingly sophisticated methods of controlling healthcare costs. In addition, in the United States, although private third-party payors tend to follow Medicare practices, no uniform or consistent policy of coverage and reimbursement for drug products exists among third-party payors. Therefore, coverage and reimbursement for drug products can differ significantly from payor to payor as well as state to state. Consequently, the coverage determination process is often a time-consuming and costly process that must be played out across many

36.

jurisdictions and different entities and which will require Brickell to provide scientific, clinical and health economics support for the use of sofpironium bromide compared to current alternatives and do so to each payor separately, with no assurance that coverage and adequate reimbursement will be obtained and in what time frame.

Further, Brickell believes that future coverage and reimbursement likely will be subject to increased restrictions both in the United States and in international markets. Third-party coverage and reimbursement for sofpironium bromide may not be available or adequate in either the United States or international markets, which could harm Brickell’s business, financial condition, operating results and prospects.

Even if sofpironium bromide obtains regulatory approval, it may fail to achieve the broad degree of physician and patient adoption and use necessary for commercial success.

The commercial success of sofpironium bromide, if approved, will depend significantly on the broad adoption and use of it by physicians and patients for approved indications, and may not be commercially successful even though the drug is shown to be safe and effective. The degree and rate of physician and patient adoption of sofpironium bromide, if approved, will depend on a number of factors, including but not limited to:

•

patient demand for approved products that treat hyperhidrosis;

•

the effectiveness of sofpironium bromide compared to other available hyperhidrosis therapies;

•

the availability of coverage and adequate reimbursement from managed care plans and other healthcare payors for sofpironium bromide;

•

the cost of treatment with sofpironium bromide in relation to alternative hyperhidrosis treatments and willingness to pay for sofpironium bromide, if approved, on the part of patients;

•

overcoming physician or patient biases toward particular therapies for the treatment of hyperhidrosis and achieving acceptance by physicians, major operators of clinics and patients of sofpironium bromide as a safe, effective and economical hyperhidrosis treatment;

•

patients’ perception of hyperhidrosis as one for which medical treatment may be appropriate and a prescription therapy may be available;

•

insurers’ willingness to see hyperhidrosis as a disease worth treating;

•

proper administration of sofpironium bromide;

•

patient satisfaction with the results and administration of sofpironium bromide and overall treatment experience;

•

limitations or contraindications, warnings, precautions or approved indications for use different than those sought by Brickell that are contained in the finalFDA-approved labeling for sofpironium bromide;

•

any FDA requirement to undertake a risk evaluation and mitigation strategy;

•

the effectiveness of Brickell’s sales, marketing, pricing, reimbursement and access, government affairs, and distribution efforts;

•

adverse publicity about sofpironium bromide or favorable publicity about competitive products;

•

new government regulations and programs, including price controls and/or limits or prohibitions on ways to commercialize drugs, such as increased scrutiny ondirect-to-consumer advertising of pharmaceuticals; and

•

potential product liability claims or other product-related litigation.

If sofpironium bromide is approved for use but fails to achieve the broad degree of physician and patient adoption necessary for commercial success, Brickell’s operating results and financial condition will be adversely affected, which may delay, prevent or limit its ability to generate revenue and continue its business.

Sofpironium bromide, if approved, will face significant competition and its failure to compete effectively may prevent it from achieving significant market penetration.

The pharmaceutical industry is characterized by rapidly advancing technologies, intense competition, less effective patent terms, and a strong emphasis on developing newer,fast-to-market proprietary therapeutics. Numerous companies are engaged in the development, patenting, manufacturing and marketing of healthcare products competitive with those that Brickell is developing, including sofpironium bromide. Brickell faces competition from a number of sources, such as pharmaceutical companies, generic drug companies, biotechnology companies and academic and research institutions, many of which have greater financial resources, marketing capabilities, sales forces, manufacturing capabilities, research and development capabilities, regulatory expertise, clinical trial expertise, intellectual property portfolios, more international reach, experience in obtaining patents and regulatory approvals for product candidates and other resources than Brickell. Some of the companies that offer competing products also have a broad range of other product offerings, large direct sales forces and long-term customer relationships with Brickell’s target physicians, which could inhibit Brickell’s market penetration efforts. In addition, sofpironium bromide, if approved, may compete with other dermatological products, includingover-the-counter treatments, for a share of some patients’, or payors’, discretionary budgets and for physicians’ attention within their clinical practices.

Brickell anticipates that sofpironium bromide would compete with other therapies currently used for hyperhidrosis, including but not limited to:

•

Self-Administered Treatments. Self-administered treatments, such as OTC and prescription topical antiperspirants, and recently approved (June 2018) Qbrexza^® (glycopyrronium) 2.4% topical cloths. Oral and compounded topical anticholinergics also may be usedoff-label.

•

Non-Surgical Office-Based Procedures. Office-based procedures have been approved by the FDA for treatment of hyperhidrosis, including intradermal injections of BOTOX^®, marketed by Allergan plc., and MiraDry^®, a microwave-based treatment marketed by Miramar Labs, Inc.

•

Surgical Treatments. Surgical treatments include techniques for the removal of sweat glands, such as excision, curettage and liposuction. Surgical procedures, such as endoscopic thoracic sympathectomy, are also used to destroy nerves that transmit activating signals to sweat glands.

To compete successfully in this market, Brickell will have to provide an attractive alternative to these existing and other new therapies. Such competition could lead to reduced market share for sofpironium bromide and contribute to downward pressure on the pricing of sofpironium bromide, which could harm Brickell’s business, financial condition, operating results and prospects. For more information about the competition Brickell faces, see “Description of Brickell’s Business—Rest of Industry.”

Due to less stringent regulatory requirements in certain foreign countries, there are many more dermatological products and procedures available for use in those international markets than are approved for use in the United States. In certain international markets, there are also fewer limitations on the claims that Brickell’s competitors can make about the effectiveness of their products and the manner in which they can market them. As a result, Brickell expects to face more competition in these markets than in the United States.

Brickell expects to face generic competition for sofpironium bromide, which could adversely affect its business, financial condition, operating results and prospects.

Upon the expiration of primary patent protection in 2031 for sofpironium bromide, and in the absence of having a pending composition of matter patent issued that would provide protection through 2040, Brickell could

38.

lose a significant portion of sales of sofpironium bromide in a short period of time, which would adversely affect its business, financial condition, operating results and prospects. While Brickell is seeking approval of the pending patent described in the section titled “Management’s Discussion and Analysis of Brickell’s Financial Condition and Results of Operations,” Brickell cannot provide any assurance as to whether it will be successful in obtaining approval of the pending patent.

Brickell has in the past relied, and expects to continue to rely, on third-party CROs and other third parties to conduct and oversee its sofpironium bromide clinical trials. If these third parties do not meet Brickell’s requirements or otherwise conduct the trials as required, Brickell may not be able to satisfy its contractual obligations or obtain regulatory approval for, or commercialize, sofpironium bromide.

Brickell has in the past relied, and expects to continue to rely, on third-party contract research organizations (“CROs”) to conduct and oversee its sofpironium bromide clinical trials and other aspects of product development. Brickell also relies on various medical institutions, clinical investigators and contract laboratories to conduct its trials in accordance with Brickell’s clinical protocols and all applicable regulatory requirements, including the FDA’s regulations and good clinical practice (“GCP”) requirements, which are an international standard meant to protect the rights and health of patients and to define the roles of clinical trial sponsors, administrators and monitors, and state regulations governing the handling, storage, security and recordkeeping for drug and biologic products. These CROs and other third parties play a significant role in the conduct of these trials and the subsequent collection and analysis of data from the clinical trials. Brickell relies heavily on these parties for the execution of its clinical trials and preclinical studies, and controls only certain aspects of their activities. Brickell and its CROs and other third-party contractors are required to comply with GCP and good laboratory practice (“GLP”) requirements, which are regulations and guidelines enforced by the FDA and comparable foreign regulatory authorities for sofpironium bromide. Regulatory authorities enforce these GCP and GLP requirements through periodic inspections of trial sponsors, principal investigators and trial sites. If Brickell or any of these third parties fail to comply with applicable GCP and GLP requirements, or reveal noncompliance from an audit or inspection, the clinical data generated in Brickell’s clinical trials may be deemed unreliable and the FDA or other regulatory authorities may require Brickell to perform additional clinical trials before approving Brickell’s or Brickell’s partners’ marketing applications. Brickell cannot assure that upon inspection by a given regulatory authority, such regulatory authority will determine that any of Brickell’s clinical or preclinical trials comply with applicable GCP and GLP requirements. In addition, Brickell’s clinical trials generally must be conducted with product produced under cGMP regulations. Brickell’s failure to comply with these regulations and policies may require it to repeat clinical trials, which would delay the regulatory approval process.

If any of Brickell’s CROs or clinical trial sites terminate their involvement in one of its clinical trials for any reason, it may not be able to enter into arrangements with alternative CROs or clinical trial sites, or do so on commercially reasonable terms. In addition, if Brickell’s relationship with clinical trial sites is terminated, it may experience the loss offollow-up information on patients enrolled in its ongoing clinical trials unless Brickell is able to transfer the care of those patients to another qualified clinical trial site. In addition, principal investigators for Brickell’s clinical trials may serve as scientific advisors or consultants to it from time to time and could receive cash or equity compensation in connection with such services. If these relationships and any related compensation result in perceived or actual conflicts of interest, the integrity of the data generated at the applicable clinical trial site may be questioned by the FDA.

Brickell currently has limited marketing capabilities and no sales organization. If Brickell is unable to establish sales and marketing capabilities on its own or through third parties, Brickell will be unable to successfully commercialize its product candidates, if approved, or generate product revenue.

Brickell currently has limited marketing capabilities and no sales organization. To commercialize Brickell’s product candidates, if approved, in the United States, Canada, the European Union, Latin America and other jurisdictions it seeks to enter, Brickell must build its marketing, sales, distribution, managerial and other

39.

non-technical capabilities or make arrangements with third parties to perform these services, and Brickell may not be successful in doing so. Although Brickell’s employees have experience in the marketing, sale and distribution of pharmaceutical products, and business development activities involving external alliances, from prior employment at other companies, Brickell as a company has no prior experience in the marketing, sale and distribution of pharmaceutical products, and there are significant risks involved in building and managing a sales organization, including its ability to hire, retain and incentivize qualified individuals, generate sufficient sales leads, provide adequate training to sales and marketing personnel, and effectively manage a geographically dispersed sales and marketing team. Any failure or delay in the development of Brickell’s internal sales, marketing, distribution and pricing/reimbursement/access capabilities would impact adversely the commercialization of these products.

To commercialize sofpironium bromide in Asia, Brickell also intends to leverage the commercial infrastructure of its partner Kaken, which will provide Brickell with resources and expertise in certain areas that are greater than it could initially build itself. Brickell may choose to collaborate with additional third parties that have direct sales forces and established distribution systems, either to augment its own sales force and distribution systems or in lieu of Brickell’s own sales force and distribution systems. If Brickell is unable to enter into such arrangements on acceptable terms or at all, it may not be able to successfully commercialize its product candidates, especially in other countries where Brickell currently does not have a foreign legal presence. The inability to commercialize successfully Brickell’s product candidates, either on its own or through collaborations with one or more third parties, would harm Brickell’s business, financial condition, operating results and prospects.

Risks Related to Brickell’s Business

Brickell currently has no products approved for sale, and it may never obtain regulatory approval to commercialize any of its product candidates.

The research, testing, manufacturing, safety surveillance, efficacy, quality control, recordkeeping, labeling, packaging, storage, approval, sale, marketing, distribution, import, export and reporting of safety and other post-market information related to its drug products are subject to extensive regulation by the FDA and other regulatory authorities in the United States and in foreign countries, and such regulations differ from country to country and frequently are revised.

Even after Brickell or its partners achieve U.S. regulatory approval for a product candidate, if any, Brickell or its partners will be subject to continued regulatory review and compliance obligations. For example, with respect to Brickell’s product candidates, the FDA may impose significant restrictions on the approved indicated uses for which the product may be marketed or on the conditions of approval. A product candidate’s approval may contain requirements for potentially costly post-approval studies and surveillance, including Phase 4 clinical trials, to monitor the safety and efficacy of the product. Brickell also will be subject to ongoing FDA obligations and continued regulatory review with respect to, among other things, the manufacturing, processing, labeling, packaging, distribution, pharmacovigilance and adverse event reporting, storage, advertising, promotion and recordkeeping for Brickell’s product candidates. These requirements include submissions of safety and other post-marketing information and reports, registration, continued compliance with cGMP requirements and with the FDA’s GCP requirements and GLP requirements, which are regulations and guidelines enforced by the FDA for all of Brickell’s product candidates in clinical and preclinical development, and for any clinical trials that it conducts post-approval, as well as continued compliance with the FDA’s laws governing commercialization of the approved product, including but not limited to the FDA’s Office of Prescription Drug Promotion (“OPDP”) regulation of promotional activities, fraud and abuse, product sampling, scientific speaker engagements and activities, formulary interactions as well as interactions with healthcare practitioners. To the extent that a product candidate is approved for sale in other countries, Brickell may be subject to similar or more onerous (i.e., prohibition ondirect-to-consumer advertising that does not exist in the United States.) restrictions and requirements imposed by laws and government regulators in those countries.

40.

In addition, manufacturers of drug and biologic products and their facilities are subject to continual review and periodic inspections by the FDA and other regulatory authorities for compliance with cGMP regulations. If Brickell or a regulatory agency discovers previously unknown problems with a product, such as adverse events of unanticipated severity or frequency, or problems with the manufacturing, processing, distribution or storage facility where, or processes by which, the product is made, a regulatory agency may impose restrictions on that product or Brickell, including requesting that Brickell initiate a product recall, or requiring notice to physicians or the public, withdrawal of the product from the market, or suspension of manufacturing.

If Brickell, its product candidates or the manufacturing facilities for its product candidates fail to comply with applicable regulatory requirements, a regulatory agency may:

•

impose restrictions on the sale, marketing or manufacturing of the product, amend, suspend or withdraw product approvals or revoke necessary licenses;

•

mandate modifications to promotional and other product-specific materials or require Brickell to provide corrective information to healthcare practitioners or in its advertising;

•

require Brickell or its partners to enter into a consent decree, which can include imposition of various fines, reimbursements for inspection costs, required due dates for specific actions, penalties for noncompliance and, in extreme cases, require an independent compliance monitor to oversee Brickell’s activities;

•

issue warning letters, bring enforcement actions, initiate surprise inspections, issue show cause notices or untitled letters describing alleged violations, which may be publicly available;

•

commence criminal investigations and prosecutions;

•

impose injunctions, suspensions or revocations of necessary approvals or other licenses;

•

impose other civil or criminal penalties;

•

suspend any ongoing clinical trials;

•

place restrictions on the kind of promotional activities that can be done;

•

delay or refuse to approve pending applications or supplements to approved applications filed by Brickell or its potential partners;

•

refuse to permit drugs or precursor chemicals to be imported or exported to or from the United States;

•

suspend or impose restrictions on operations, including costly new manufacturing requirements; or

•

seize or detain products or require Brickell or its partners to initiate a product recall.

The regulations, policies or guidance of the FDA and other applicable government agencies may change, and new or additional statutes or government regulations may be enacted, including at the state and local levels, which can differ by geography and could prevent or delay regulatory approval of Brickell’s product candidates or further restrict or regulate post-approval activities. Brickell cannot predict the likelihood, nature or extent of adverse government regulations that may arise from future legislation or administrative action, either in the United States or abroad. If Brickell is not able to achieve and maintain regulatory compliance, it may not be permitted to commercialize its product candidates, which would adversely affect its ability to generate revenue and achieve or maintain profitability.

Brickell has conducted and may in the future conduct clinical trials for its product candidates outside the United States, and the FDA and applicable foreign regulatory authorities may not accept data from such trials.

Brickell has conducted and may in the future choose to conduct one or more of its clinical trials outside of the United States. Although the FDA or applicable foreign regulatory authority may accept data from clinical

41.

trials conducted outside the United States or the applicable jurisdiction, acceptance of such study data by the FDA or applicable foreign regulatory authority may be subject to certain conditions or exclusion. Where data from foreign clinical trials are intended to serve as the basis for marketing approval in the United States, the FDA will not approve the application on the basis of foreign data alone unless such data are applicable to the U.S. population and U.S. medical practice; the studies were performed by clinical investigators of recognized competence; and the data are considered valid without the need for anon-site inspection by the FDA or, if the FDA considers such an inspection to be necessary, the FDA is able to validate the data through anon-site inspection or other appropriate means. Many foreign regulatory bodies have similar requirements. In addition, such foreign studies would be subject to the applicable local laws of the foreign jurisdictions where the studies are conducted. There can be no assurance the FDA or applicable foreign regulatory authority will accept data from trials conducted outside of the United States or the applicable home country. If the FDA or applicable foreign regulatory authority does not accept such data, it would likely result in the need for additional trials, which would be costly and time-consuming and delay aspects of Brickell’s business plan.

Brickell may face product liability exposure, and if successful claims are brought against it, Brickell may incur substantial liability if its insurance coverage for those claims is inadequate.

Brickell faces an inherent risk of product liability or similar causes of action as a result of the clinical testing of its product candidates and will face an even greater risk if Brickell commercializes any products. This risk exists even if a product is approved for commercial sale by the FDA and manufactured in facilities licensed and regulated by the FDA or an applicable foreign regulatory authority and notwithstanding Brickell complying with applicable laws on promotional activity. Brickell’s products and product candidates are designed to affect important bodily functions and processes. Any side effects, manufacturing defects, misuse or abuse associated with Brickell’s product candidates could result in injury to a patient or potentially even death. Brickell cannot offer any assurance that it will not face product liability suits in the future, nor can it assure that its insurance coverage will be sufficient to cover its liability under any such cases.

In addition, a liability claim may be brought against Brickell even if its product candidates merely appear to have caused an injury. Product liability claims may be brought against Brickell by consumers, healthcare providers, pharmaceutical companies or others selling or otherwise coming into contact with its product candidates, among others, and under some circumstances even government agencies. If Brickell cannot successfully defend itself against product liability or similar claims, it will incur substantial liabilities, reputational harm and possibly injunctions and punitive actions. In addition, regardless of merit or eventual outcome, product liability claims may result in:

•

withdrawal or delay of recruitment or decreased enrollment rates of clinical trial participants;

•

termination or increased government regulation of clinical trial sites or entire trial programs;

•

the inability to commercialize Brickell’s product candidates;

•

decreased demand for Brickell’s product candidates;

•

impairment of Brickell’s business reputation;

•

product recall or withdrawal from the market or labeling, marketing or promotional restrictions;

•

substantial costs of any related litigation or similar disputes;

•

distraction of management’s attention and other resources from Brickell’s primary business;

•

significant delay in product launch;

•

substantial monetary awards to patients or other claimants against Brickell that may not be covered by insurance;

•

withdrawal of reimbursement or formulary inclusion; or

•

loss of revenue.

42.

Brickell has obtained product liability insurance coverage for its clinical trials. Large judgments have been awarded in class action or individual lawsuits based on drugs that had unanticipated side effects. Brickell’s insurance coverage may not be sufficient to cover all of its product liability-related expenses or losses and may not cover it for any expenses or losses it may suffer. Moreover, insurance coverage is becoming increasingly expensive, restrictive and narrow, and, in the future, Brickell may not be able to maintain adequate insurance coverage at a reasonable cost, in sufficient amounts or upon adequate terms to protect it against losses due to product liability or other similar legal actions. Brickell will need to increase its product liability coverage if any of its product candidates receive regulatory approval, which will be costly, and it may be unable to obtain this increased product liability insurance on commercially reasonable terms or at all and for all geographies in which Brickell wishes to launch. A successful product liability claim or series of claims brought against Brickell, if judgments exceed its insurance coverage, could decrease its cash and harm its business, financial condition, operating results and future prospects.

Brickell’s employees, independent contractors, principal investigators, other clinical trial staff, consultants, vendors, CROs and any partners with whom Brickell may collaborate may engage in misconduct or other improper activities, including noncompliance with regulatory standards and requirements.

Brickell is exposed to the risk that its employees, independent contractors, principal investigators, other clinical trial staff, consultants, vendors, CROs and any partners with which Brickell may collaborate may engage in fraudulent or other illegal activity. Misconduct by these persons could include intentional, reckless, gross or negligent misconduct or unauthorized activity that violates: laws or regulations, including those laws requiring the reporting of true, complete and accurate information to the FDA or foreign regulatory authorities; manufacturing standards; federal, state and foreign healthcare fraud and abuse laws and data privacy; anticorruption laws, antikickback and Medicare/Medicaid rules, or laws that require the true, complete and accurate reporting of financial information or data, books and records. If any such or similar actions are instituted against Brickell and Brickell is not successful in defending itself or asserting Brickell’s rights, those actions could have a significant impact on Brickell’s business, including the imposition of civil, criminal and administrative and punitive penalties, damages, monetary fines, possible exclusion from participation in Medicare, Medicaid and other federal healthcare programs, debarments, contractual damages, reputational harm, diminished profits and future earnings, injunctions, and curtailment or cessation of Brickell’s operations, any of which could adversely affect Brickell’s ability to operate Brickell’s business and Brickell’s operating results.

Brickell may be subject to risks related tooff-label use of its product candidates.

The FDA strictly regulates the advertising and promotion of drug products, and drug products may only be marketed or promoted for their FDA approved uses, consistent with the product’s approved labeling. Advertising and promotion of any product candidate that obtains approval in the United States will be heavily scrutinized by the FDA, the Department of Justice, the Office of Inspector General of the Department of Health and Human Services, state attorneys general, members of Congress and the public. Violations, including promotion of Brickell’s products for unapproved oroff-label uses, are subject to enforcement letters, inquiries and investigations, and civil, criminal and/or administrative sanctions by the FDA. Additionally, advertising and promotion of any product candidate that obtains approval outside of the United States will be heavily scrutinized by relevant foreign regulatory authorities.

Even if Brickell obtains regulatory approval for its product candidates, the FDA or comparable foreign regulatory authorities may require labeling changes or impose significant restrictions on a product’s indicated uses or marketing, or impose ongoing requirements for potentially costly post-approval studies or post-market surveillance.

In the United States, engaging in impermissible promotion of Brickell’s product candidates foroff-label uses can also subject it to false claims litigation under federal and state statutes, which can lead to civil, criminal and/or administrative penalties and fines and agreements, such as a corporate integrity agreement, that materially

43.

restrict the manner in which Brickell promotes or distributes its product candidates. If Brickell does not lawfully promote its products once they have received regulatory approval, Brickell may become subject to such litigation and, if it is not successful in defending against such actions, those actions could have a material adverse effect on its business, financial condition and operating results and even result in having an independent compliance monitor assigned to audit Brickell’s ongoing operations for a lengthy period of time.

Other than sofpironium bromide, Brickell’s product candidates are at the early stages of clinical and regulatory development.

Brickell is currently evaluating the next clinical development steps forBBI-3000 andBBI-6000 as each is in an early stage of clinical (prior to Phase 3) andpre-clinical development. The regulatory approval processes of the FDA and comparable foreign authorities are lengthy, time consuming and inherently unpredictable, especially for early stage product candidates. The time required to obtain approval for early stage product candidates from the FDA and comparable foreign authorities is unpredictable but typically takes many years, involves significant costs and depends upon numerous factors, including the substantial discretion of the regulatory authorities. In addition, approval policies, regulations, or the type and amount of clinical data necessary to gain approval may change during the course of a product candidate’s clinical development and may vary among jurisdictions. Brickell’s early stage product candidates will require substantial additional preclinical and clinical development before Brickell will be able to submit an application to the FDA, if at all. Accordingly, Brickell cannot assure you that it will be able to seek or obtain regulatory approval for any of its early stage product candidates.

Brickell’s clinical trials may fail to demonstrate the safety and efficacy ofBBI-3000 orBBI-6000, or serious adverse or unacceptable side effects may be identified during their development, which could prevent or delay marketing approval and commercialization, increase Brickell’s costs or necessitate the abandonment or limitation of the development ofBBI-3000 orBBI-6000.

Before obtaining marketing approvals for the commercial sale ofBBI-3000 andBBI-6000, Brickell must demonstrate through lengthy, complex and expensive preclinical testing and clinical trials thatBBI-3000 andBBI-6000 are both safe and effective for use in each target indication, and failures can occur at any stage of testing. Clinical trials often fail to demonstrate safety and are associated with side effects or have characteristics that are unexpected. Based on the safety profile seen in clinical testing, Brickell may need to abandon development or limit development to more narrow uses in which the side effects or other characteristics are less prevalent, less severe or more tolerable from a risk-benefit perspective. The FDA or an IRB may also require that Brickell suspend, discontinue, or limit clinical trials based on safety information. Such findings could further result in regulatory authorities failing to provide marketing authorization forBBI-3000 orBBI-6000. Many drug candidates that initially showed promise in early stage testing and which were efficacious have later been found to cause side effects that prevented further development of the drug candidate and, in extreme cases, the side effects were not seen until after the drug was marketed, causing regulators to remove the drug from the market post-approval.

Brickell may choose not to continue developing or commercializing any of its early stage product candidates at any time during development or after approval, which would reduce or eliminate its potential return on investment for those product candidates.

At any time, Brickell may decide to discontinue the development of any of its early stage product candidates for a variety of reasons, including the appearance of new technologies that make its product obsolete, competition from a competing product or changes in or failure to comply with applicable regulatory requirements. If Brickell terminates a program in which it has invested significant resources, Brickell will not receive any return on its investment and it will have missed the opportunity to have allocated those resources to potentially more productive uses.

44.

Healthcare reform measures could hinder or prevent the commercial success of Brickell’s product candidates.

The current presidential administration and certain members of the majority of the U.S. Congress have sought to repeal all or part of the Patient Protection and Affordable Care Act, as amended by the Health Care and Education Reconciliation Act (collectively, “Affordable Care Act”), and implement a replacement program. For example, theso-called “individual mandate” was repealed as part of tax reform legislation adopted in December 2017, such that the shared responsibility payment for individuals who fail to maintain minimum essential coverage under section 5000A of the Code was eliminated beginning in 2019. In addition, litigation may prevent some or all of the Affordable Care Act legislation from taking effect. For example, on December 14, 2018, the U.S. District Court for the Northern District of Texas held that the individual mandate is a critical and inseverable feature of the Affordable Care Act, and therefore, because it was repealed as part of the tax reform legislation, the remaining provisions of the Affordable Care Act are invalid as well. The impact of this ruling is stayed as it is appealed to the Fifth Circuit Court of Appeals. While the ruling will have no immediate effect, it is unclear how this decision, and subsequent appeals, if any, will impact the law. In 2019 and beyond, Brickell may face additional uncertainties as a result of likely federal and administrative efforts to repeal, substantially modify or invalidate some or all of the provisions of the Affordable Care Act. There is no assurance that the Affordable Care Act, as amended in the future, will not adversely affect Brickell’s business and financial results.

Additionally, in October 2018, the U.S. President proposed to lower Medicare Part B drug prices, in addition to contemplating other measures to lower prescription drug prices. While this proposal has not yet been enacted, Brickell expects that additional state and federal healthcare reform measures will be adopted in the future, any of which could limit the amounts that federal and state governments will pay for healthcare products and services, which could result in reduced demand for its product candidates if approved or additional pricing pressures.

There are also calls to ban alldirect-to-consumer advertising of pharmaceuticals, which would limit Brickell’s ability to market its product candidates. The United States is in a minority of jurisdictions that allow this kind of advertising and its removal could limit the potential reach of a marketing campaign.

Brickell may also be subject to stricter healthcare laws, regulation and enforcement, and its failure to comply with those laws could adversely affect its business, operations and financial condition.

Certain federal and state healthcare laws and regulations pertaining to fraud and abuse and patients’ rights are and will be applicable to Brickell’s business. Brickell is subject to regulation by both the federal government and the states in which it or its partners conduct business. The healthcare laws and regulations that may affect Brickell’s ability to operate include: the federal Anti-Kickback Statute; federal civil and criminal false claims laws and civil monetary penalty laws; the federal Health Insurance Portability and Accountability Act of 1996, as amended by the Health Information Technology for Economic and Clinical Health Act; the Prescription Drug Marketing Act (for sampling of drug product among other things); the federal physician sunshine requirements under the Affordable Care Act; the Foreign Corrupt Practices Act as it applies to activities outside of the United States; the new federalRight-to-Try legislation; and state law equivalents of many of the above federal laws.

Because of the breadth of these laws and the narrowness of the statutory exceptions and safe harbors available, it is possible that some of Brickell’s business activities could be subject to challenge under one or more of such laws. In addition, recent healthcare reform legislation has strengthened these laws. For example, the recently enacted Affordable Care Act, among other things, amended the intent requirement of the federal Anti-Kickback Statute and certain criminal healthcare fraud statutes. A person or entity no longer needs to have actual knowledge of the statute or specific intent to violate it. In addition, the Affordable Care Act provided that the government may assert that a claim including items or services resulting from a violation of the federal Anti-Kickback Statute constitutes a false or fraudulent claim for purposes of the federal civil False Claims Act.

Achieving and sustaining compliance with these laws may prove costly. In addition, any action against Brickell for violation of these laws, even if Brickell successfully defends against it, could cause Brickell to incur

45.

significant legal expenses and divert its management’s attention from the operation of its business and result in reputational damage. If Brickell’s operations are found to be in violation of any of the laws described above or any other governmental laws or regulations that apply to Brickell, it may be subject to penalties, including administrative, civil and criminal penalties, damages, including punitive damages, fines, disgorgement, the exclusion from participation in federal and state healthcare programs, individual imprisonment or the curtailment or restructuring of its operations, and injunctions, any of which could adversely affect Brickell’s ability to operate its business and its financial results.

Brickell intends toin-license and acquire product candidates and may engage in other strategic transactions, which could impact its liquidity, increase its expenses and present significant distractions to its management.

Brickell’s strategy is toin-license and acquire product candidates and it may engage in other strategic transactions. Additional potential transactions that Brickell may consider include a variety of different business arrangements, including spin-offs, strategic partnerships, joint ventures, restructurings, divestitures, business combinations and investments. Any such transaction may require Brickell to incurnon-recurring or other charges, may increase its near- and long-term expenditures and may pose significant integration challenges or disrupt its management or business, which could adversely affect its operations and financial results. Accordingly, there can be no assurance that Brickell will undertake or successfully complete any transactions of the nature described above, and any transaction that it does complete could harm its business, financial condition, operating results and prospects. Brickell has no current plan, commitment or obligation to enter into any transaction described above, and Brickell is not engaged in discussions related to additional partnerships.

Brickell’s failure successfully toin-license, acquire, develop and market additional product candidates or approved products would impair its ability to grow its business.

Brickell intends toin-license, acquire, develop and market additional products and product candidates. Because Brickell’s internal research and development capabilities are limited, it may be dependent on pharmaceutical companies, academic or government scientists and other researchers to sell or license products or technology to it. The success of this strategy depends partly on Brickell’s ability to identify and select promising pharmaceutical product candidates and products, negotiate licensing or acquisition agreements with their current owners, and finance these arrangements.

The process of proposing, negotiating and implementing a license or acquisition of a product candidate or approved product is lengthy and complex. Other companies, including some with substantially greater financial, marketing, sales and other resources, may compete with Brickell for the license or acquisition of product candidates and approved products. Brickell has limited resources to identify and execute the acquisition orin-licensing of third-party products, businesses and technologies and integrate them into its current infrastructure. Moreover, Brickell may devote resources to potential acquisitions or licensing opportunities that are never completed, or Brickell may fail to realize the anticipated benefits of such efforts. Brickell may not be able to acquire the rights to additional product candidates on terms that it finds acceptable or at all.

Further, any product candidate that Brickell acquires may require additional development efforts prior to commercial sale, including preclinical or clinical testing and approval by the FDA and applicable foreign regulatory authorities. All product candidates are prone to risks of failure typical of pharmaceutical product development, including the possibility that a product candidate will not be shown to be sufficiently safe and effective for approval by regulatory authorities. In addition, Brickell cannot provide assurance that any approved products that it acquires will be manufactured or sold profitably or achieve market acceptance.

Risks Related to Brickell’s Dependence on Third Parties

Under the Funding Agreement, NovaQuest has the right to suspend product development payments in certain circumstances.

On June 2, 2019, Brickell and NovaQuest entered into the Funding Agreement, pursuant to which NovaQuest has agreed, following consummation of the Merger, to partially fund Brickell’s expenses relating to product development activities in respect of sofpironium bromide, subject to the terms and conditions contained in the Funding Agreement. NovaQuest may suspend its payments under the Funding Agreement in certain limited circumstances, including: (i) adverse regulatory events relating to sofpironium bromide; (ii) termination of any material clinical study in respect of sofpironium bromide; (iii) an event reasonably expected to delay U.S. approval or launch of sofpironium bromide by 12 months or more; (iv) a material amendment of the study protocol for Brickell’s Phase 3 clinical trials in respect of its sofpironium bromide product candidate without NovaQuest’s consent; (v) if Brickell determines that sofpironium bromide is unsafe; (vi) the failure of sofpironium bromide to achieve the primary endpoints for its Phase 3 clinical trials; (vii) sofpironium bromide receiving a finalnon-approval letter from the FDA or European Medicines Agency; and (viii) if certain of Brickell’s senior executives cease to work for Brickell and Brickell does not hire replacements reasonably acceptable to NovaQuest in a reasonable time. NovaQuest’s obligation to make the payments will resume upon NovaQuest’s notice to Brickell that the condition allowing NovaQuest to suspend payments has been resolved or cured. NovaQuest may terminate its obligation to pay any further payments if such condition is not resolved or cured within 12 months. If NovaQuest’s payment obligations terminate in these circumstances, Brickell will remain obligated to make the milestone payments contemplated in the Funding Agreement to NovaQuest in the event Brickell nonetheless receives FDA approval for sofpironium bromide, and Brickell will remain obligated to make revenue sharing payments in the territory covered by the Funding Agreement in the event Brickell launches sofpironium bromide anywhere in that territory.

If Brickell suspends or terminates the development program for sofpironium bromide under certain circumstances, Brickell will be obligated to pay NovaQuest $25 million plus interest.

Under the Funding Agreement with NovaQuest, Brickell is not permitted to suspend or discontinue the development program in respect of sofpironium bromide except in certain circumstances. If Brickell suspends or terminates the development program following completion of Phase 3 clinical trials because the FDA requires an additional study or additional, unexpected development work, and Brickell reasonably determines that the additional study or work would take longer than 18 months to complete or cost more than an established threshold, Brickell is entitled to terminate the development program. In that case, Brickell would be obligated to pay NovaQuest plus interest from the date of the Funding Agreement until the date on which the payment is made (however, in the event that Brickell terminates its development program for sofpromium bromide for certain reasons, including serious safety issues, a failure of the product’s Phase 3 studies, or the failure of the FDA to approve the product, Brickell will not be obligated to make any payments to NovaQuest). If Brickell subsequently resumes development of sofpironium bromide, Brickell will remain obligated to make the milestone payments contemplated in the Funding Agreement to NovaQuest in the event Brickell nonetheless receives FDA approval for sofpironium bromide, and Brickell will remain obligated to make revenue sharing payments in the territory covered by the Funding Agreement in the event Brickell launches a sofpironium product anywhere in that territory, with any such payment made upon termination of the program credited against the milestone payment or revenue sharing payments.

If Brickell breaches the Funding Agreement, NovaQuest may terminate the agreement and exercise rights under a related Security Agreement, including foreclosing on Brickell’s assets relating to sofpironium bromide in the United States and accelerating certain payments.

Under Brickell’s Funding Agreement with NovaQuest, Brickell makes various representations and warranties and commits to comply with various covenants. NovaQuest may terminate the Funding Agreement and terminate its obligation to make certain payments in the event of Brickell’s material uncured breach of a

47.

representation or covenant under the Funding Agreement. Brickell will also enter into a Security Agreement (the “Security Agreement”) with NovaQuest immediately following consummation of the Merger. Under the Security Agreement, NovaQuest will be able to exercise certain rights in the event of an event of default. An event of default would occur if (i) Brickell fails to make payments due under the Funding Agreement, (ii) Brickell terminates the Funding Agreement under circumstances giving rise to a payment obligation to NovaQuest and fails to make the required payment, as described above under “—If Brickell suspends or terminates the development program for Brickell’s sofpironium bromide product candidate under certain circumstances, Brickell will be obligated to pay NovaQuest $25 million plus interest,” (iii) if Brickell fails to comply with a covenant to maintain certain minimum cash balances specified in the Funding Agreement, or (iv) the occurrence of certain insolvency events affecting Brickell or other related entities that are, or become parties to, the Security Agreement. NovaQuest’s rights following an event of default include, among other things, foreclosing on Brickell’s assets in the territory relating to Brickell’s sofpironium bromide product candidate and, in certain circumstances, accelerating payment obligations under the Funding Agreement.

Brickell expects to rely on its collaboration with third-partyout-license partners for the successful development and commercialization of its product candidates.

Brickell expects to rely upon the efforts of third-partyout-license partners for the successful development and commercialization of Brickell’s current and future product candidates. The clinical and commercial success of Brickell’s product candidates may depend upon maintaining successful relationships with third-partyout-license partners which are subject to a number of significant risks, including the following:

•

Brickell’s partners’ ability to execute their responsibilities in a timely, cost-efficient and compliant manner;

•

reduced control over delivery and manufacturing schedules;

•

price increases and product reliability;

•

manufacturing deviations from internal or regulatory specifications;

•

quality incidents;

•

the failure of partners to perform their obligations for technical, market or other reasons;

•

misappropriation of Brickell’s current or future product candidates; and

•

other risks in potentially meeting Brickell’s current and future product commercialization schedule or satisfying the requirements of itsend-users.

Brickell cannot assure you that it will be able to establish or maintain third-partyout-license partner relationships in order to successfully develop and commercialize its product candidates.

Brickell relies completely on third-party contractors to supply, manufacture and distribute clinical drug supplies for its product candidates, including certain sole-source suppliers and manufacturers; Brickell intends to rely on third parties for commercial supply, manufacturing and distribution if any of its product candidates receive regulatory approval; and Brickell expects to rely on third parties for supply, manufacturing and distribution of preclinical, clinical and commercial supplies of any future product candidates.

Brickell does not currently have, nor does it plan to acquire, the infrastructure or capability to supply, store, manufacture or distribute preclinical, clinical or commercial quantities of drug substances or products. Additionally, Brickell has not entered into a long-term commercial supply agreement to provide it with such drug substances or products. As a result, Brickell’s ability to develop its product candidates is dependent, and Brickell’s ability to supply its products commercially will depend, in part, on Brickell’s ability to obtain the APIs and other substances and materials used in its product candidates successfully from third parties and to have finished products manufactured by third parties in accordance with regulatory requirements and in sufficient

48.

quantities for preclinical and clinical testing and commercialization. If Brickell fails to develop and maintain supply and other technical relationships with these third parties, it may be unable to continue to develop or commercialize its products and product candidates.

Brickell does not have direct control over whether its contract suppliers and manufacturers will maintain current pricing terms, be willing to continue supplying Brickell with APIs and finished products or maintain adequate capacity and capabilities to serve its needs, including quality control, quality assurance and qualified personnel. Brickell is dependent on its contract suppliers and manufacturers forday-to-day compliance with applicable laws and cGMPs for production of both APIs and finished products. If the safety or quality of any product or product candidate or component is compromised due to a failure to adhere to applicable laws or for other reasons, Brickell may not be able to commercialize or obtain regulatory approval for the affected product or product candidate successfully, and Brickell may be held liable for injuries sustained as a result.

In order to conduct larger or late-stage clinical trials for its product candidates and supply sufficient commercial quantities of the resulting drug product and its components, if that product candidate is approved for sale, Brickell’s contract manufacturers and suppliers will need to produce its drug substances and product candidates in larger quantities, more cost-effectively and, in certain cases, at higher yields than they currently achieve. If Brickell’s third-party contractors are unable to scale up the manufacture of any of its product candidates successfully in sufficient quality and quantity and at commercially reasonable prices, or are shut down or put on clinical hold by government regulators, and Brickell is unable to find one or more replacement suppliers or manufacturers capable of production at a substantially equivalent cost in substantially equivalent volumes and quality, and Brickell is unable to transfer the processes successfully on a timely basis, the development of that product candidate and regulatory approval or commercial launch for any resulting products may be delayed, or there may be a shortage in supply, either of which could significantly harm its business, financial condition, operating results and prospects.

Brickell expects to continue to depend on third-party contract suppliers and manufacturers for the foreseeable future. Brickell’s supply and manufacturing agreements, if any, do not guarantee that a contract supplier or manufacturer will provide services adequate for its needs. Additionally, any damage to or destruction of Brickell’s third-party manufacturer’s or suppliers’ facilities or equipment, even by force majeure, may significantly impair its ability to have its products and product candidates manufactured on a timely basis. Brickell’s reliance on contract manufacturers and suppliers further exposes it to the possibility that they, or third parties with access to their facilities, will have access to and may misappropriate Brickell’s trade secrets or other proprietary information. In addition, the manufacturing facilities of certain of Brickell’s suppliers may be located outside of the United States. This may give rise to difficulties in importing Brickell’s products or product candidates or their components into the United States or other countries.

Manufacturing and supply of the APIs and other substances and materials used in Brickell’s product candidates and finished drug products is a complex and technically challenging undertaking, and there is potential for failure at many points in the manufacturing, testing, quality control and assurance and distribution supply chain, as well as the potential for latent defects after products have been manufactured and distributed.

Manufacturing and supply of APIs, other substances and materials and finished drug products is technically challenging. Changes beyond Brickell’s direct control can impact the quality, volume, price and successful delivery of its products and product candidates and can impede, delay, limit or prevent the successful development and commercialization of its products and product candidates. Mistakes and mishandling are not uncommon despite reasonable best efforts and can affect successful production and supply. Some of these risks include but are not limited to:

•

failure of Brickell’s manufacturers to follow cGMP or other legal requirements or mishandling of or adulterating product while in production or in preparation for transit;

49.

•

inability of Brickell’s contract suppliers and manufacturers to efficiently and cost-effectively increase and maintain high yields and batch quality, consistency and stability;

•

difficulty in establishing optimal drug delivery substances and techniques, production and storage methods and packaging and shipment processes;

•

challenges in designing effective drug delivery substances and techniques especially in light of competitor options;

•

transportation and import/export risk, particularly given the global nature of Brickell’s supply chain;

•

delays in analytical results or failure of analytical techniques that Brickell depends on for quality control/assurance and release of product;

•

natural disasters, strikes and labor disputes, war and terrorism, financial distress, lack of raw material supply, issues with facilities and equipment or other forms of disruption to business operations of Brickell’s contract manufacturers and suppliers; and

•

latent defects that may become apparent after product has been released and even sold and used and that may result in recall and destruction of product.

Any of these factors could result in delays or higher costs in connection with Brickell’s clinical trials, regulatory submissions, required approvals or commercialization of its products, which could harm its business, financial condition, operating results and prospects.

Risks Related to Brickell’s Financial Operations

Brickell will need to raise additional financing in the future to fund Brickell’s operations, which may not be available to it on favorable terms or at all.

Brickell will require substantial additional funds to conduct the costly and time-consuming clinical efficacy trials necessary to pursue regulatory approval of each potential product candidate and to continue the development of sofpironium bromide in new indications or uses. Brickell’s future capital requirements will depend upon a number of factors, including: the number and timing of future product candidates in the pipeline; progress with and results from preclinical testing and clinical trials; the ability to manufacture sufficient drug supplies to complete preclinical and clinical trials; the costs involved in preparing, filing, acquiring, prosecuting, maintaining and enforcing patent and other intellectual property claims; and the time and costs involved in obtaining regulatory approvals and favorable reimbursement or formulary acceptance. Raising additional capital may be costly or difficult to obtain and could significantly dilute stockholders’ ownership interests or inhibit Brickell’s ability to achieve its business objectives. If Brickell raises additional funds through public or private equity offerings, the terms of these securities may include liquidation or other preferences that adversely the rights of its common stockholders. Further, to the extent that Brickell raises additional capital through the sale of common stock or securities convertible or exchangeable into common stock, your ownership interest in the combined company will be diluted. In addition, any debt financing may subject Brickell to fixed payment obligations and covenants limiting or restricting its ability to take specific actions, such as incurring additional debt, making capital expenditures or declaring dividends. If Brickell raises additional capital through marketing and distribution arrangements or other collaborations, strategic alliances or licensing arrangements with third parties, Brickell may have to relinquish certain valuable intellectual property or other rights to its product candidates, technologies, future revenue streams or research programs or grant licenses on terms that may not be favorable to it. Even if Brickell were to obtain sufficient funding, there can be no assurance that it will be available on terms acceptable to Brickell or its stockholders.

Brickell’s operating results and liquidity needs could be affected negatively by global market fluctuations and economic downturn.

Brickell’s operating results and liquidity could be affected negatively by global economic conditions generally, both in the United States and elsewhere around the world. The market for discretionary medical

50.

products and procedures may be particularly vulnerable to unfavorable economic conditions. Some patients may consider sofpironium bromide as discretionary, and if full reimbursement for the product is not available, demand for the product may be tied to the discretionary,out-of-pocket cash-spending levels of Brickell’s targeted patient populations. Domestic and international equity and debt markets have experienced and may continue to experience heightened volatility and turmoil based on domestic and international economic conditions and concerns. In the event these economic conditions and concerns continue or worsen and the markets continue to remain volatile, or a bear market ensues in the U.S. stock market given the current bull market is the longest on record, Brickell’s operating results and liquidity could be affected adversely by those factors in many ways, including weakening demand for sofpironium bromide, making it more difficult for Brickell to raise funds if necessary, and Brickell’s stock price may decline.

Brickell expects its stock price to be highly volatile.

The market price of Brickell’s shares following the Merger could be subject to significant fluctuations. Market prices for securities of biotechnology and other life sciences companies historically have been particularly volatile subject even to large daily price swings. Some of the factors that may cause the market price of Brickell’s shares to fluctuate include, but are not limited to:

•

the ability of the combined company to obtain timely regulatory approvals for sofpironium bromide or future product candidates, and delays or failures to obtain such approvals;

•

failure of sofpironium bromide, if approved, to achieve commercial success;

•

issues in manufacturing sofpironium bromide or future product candidates;

•

the results of current and any future clinical trials of sofpironium bromide;

•

failure of other Brickell product candidates, if approved, to achieve commercial success;

•

the entry into, or termination of, or breach by partners of key agreements, including key commercial partner agreements;

•

the initiation of, material developments in, or conclusion of any litigation to enforce or defend any intellectual property rights or defend against the intellectual property rights of others;

•

announcements of any dilutive equity financings;

•

announcements by commercial partners or competitors of new commercial products, clinical progress or the lack thereof, significant contracts, commercial relationships or capital commitments;

•

the introduction of technological innovations or new therapies or formulations that compete with sofpironium bromide;

•

failure to elicit meaningful stock analyst coverage and downgrades of the company’s stock by analysts; and

•

the loss of key employees.

Moreover, the stock markets in general have experienced substantial volatility in our industry that has often been unrelated to the operating performance of individual companies or a certain industry segment. These broad market fluctuations may also adversely affect the trading price of the combined company’s shares.

In the past, following periods of volatility in the market price of a company’s securities, shareholders have often instituted class action securities litigation against those companies. Such litigation, if instituted, could result in substantial costs and diversion of management attention and resources, which could significantly harm the combined company’s profitability and reputation. In addition, such securities litigation often has ensued after a reverse merger or other merger and acquisition activity of the type engaged in here by Brickell with Vical. Such litigation if brought could impact negatively the combined company’s business.

51.

Brickell’s operating results may fluctuate significantly, which makes its future operating results difficult to predict and could cause its operating results to fall below expectations.

Brickell’s operations to date have been limited primarily to researching and developing sofpironium bromide and undertaking preclinical studies and clinical trials of sofpironium bromide. Brickell has not yet obtained regulatory approvals for sofpironium bromide in any country. Consequently, any predictions you or Brickell make about its future success or viability may not be as accurate as they could be if Brickell had a longer operating history or approved products on the market. Brickell’s revenue and profitability will depend on development funding and the achievement of development and clinical milestones under an agreement with Kaken, as well as any potential future collaboration and license agreements and sales of sofpironium bromide or future products, if approved. Theseup-front and milestone payments may vary significantly from period to period, and any such variance could cause a significant fluctuation in Brickell’s operating results from one period to the next. In addition, Brickell will measure compensation cost for stock-based awards made to employees at the grant date of the award, based on the fair value of the award as determined by its board of directors and recognize the cost as an expense over the employee’s requisite service period. As the variables that Brickell uses as a basis for valuing these awards change over time, including its underlying stock price and stock price volatility, the magnitude of the expense that Brickell must recognize may vary significantly. Furthermore, Brickell’s operating results may fluctuate due to a variety of other factors, many of which are outside of its control and may be difficult to predict.

The former Vical stockholders may sell their shares of the combined company.

Pursuant to the Merger Agreement, the stockholders of Vical are not required to agree to restrictions on selling their stock. As such, the former Vical stockholders may sell their stock of the combined company after the Merger, which could lead to a decline in the market value of Brickell’s stock and could negatively impact future issuances of the combined company’s equity securities.

The combined company will incur costs and demands upon management as a result of complying with the laws and regulations affecting public companies.

The combined company will incur significant legal, accounting and other expenses that Brickell did not incur as a private company, including costs associated with public company reporting and other SEC requirements. The combined company also will incur costs associated with corporate governance requirements, including requirements under the Sarbanes-Oxley Act, as well as new rules implemented by the SEC and Nasdaq. These rules and regulations are expected to increase the combined company’s legal and financial compliance costs and to make some activities more time-consuming and costly. The combined company’s executive officers and other personnel will need to devote substantial time to gaining expertise regarding operations as a public company and compliance with applicable laws and regulations. These rules and regulations may also make it expensive for the combined company to operate its business.

The combined company is expected to take advantage of reduced disclosure and governance requirements applicable to smaller reporting companies, which could result in its common stock being less attractive to investors.

Following the Merger, the combined company is expected to have a public float of less than $250 million and therefore will qualify as a smaller reporting company under the rules of the SEC. As a smaller reporting company the combined company will be able to take advantage of reduced disclosure requirements, such as simplified executive compensation disclosures and reduced financial statement disclosure requirements in its SEC filings. Decreased disclosures in the combined company’s SEC filings due to its status as a smaller reporting company may make it harder for investors to analyze its results of operations and financial prospects. We cannot predict if investors will find the combined company’s common stock less attractive if it relies on these exemptions. If some investors find its common stock less attractive as a result, there may be a less active trading

52.

market for its common stock and its stock price may be more volatile. The combined company may take advantage of the reporting exemptions applicable to a smaller reporting company until it is no longer a smaller reporting company, which status would end once it has a public float greater than $250 million. In that event, the combined company could still be a smaller reporting company if its annual revenues were below $100 million and it has a public float of less than $700 million.

The combined company does not anticipate paying any dividends in the foreseeable future.

The current expectation is that the combined company will retain its future earnings to fund the development and growth of the company’s business. As a result, capital appreciation, if any, of the shares of the combined company will be your sole source of gain, if any, for the foreseeablefuture.

If Brickell fails to attract and retain management and other key personnel, it may be unable to continue to successfully develop or commercialize its product candidates or otherwise implement its business plan.

Brickell’s ability to compete in the highly competitive pharmaceuticals industry depends on its ability to attract and retain highly qualified managerial, scientific, medical, legal, sales and marketing and other personnel. Brickell is highly dependent on its management and scientific personnel. The loss of the services of any of these individuals could impede, delay or prevent the successful development of Brickell’s product pipeline, completion of its planned clinical trials, commercialization of its product candidates orin-licensing or acquisition of new assets and could impact negatively its ability to implement successfully its business plan. If Brickell loses the services of any of these individuals, it might not be able to find suitable replacements on a timely basis or at all, and its business could be harmed as a result. Brickell might not be able to attract or retain qualified management and other key personnel in the future due to the intense competition for qualified personnel among biotechnology, pharmaceutical and other businesses.

Brickell’s ability to use its net operating loss carry-forwards to offset future taxable income may be subject to certain limitations.

As of December 31, 2018, Brickell had approximately $36.5 million of federal and $30.9 million of state operating loss carry-forwards available to offset future taxable income, which expire in varying amounts beginning in 2030 for federal and state purposes if unused. It is possible that Brickell will not generate taxable income in time to use these loss carry-forwards before their expiration. Brickell’s net operating loss carryforwards may also be subject to limitation as a result of prior shifts in equity ownership and/or the Merger. In addition, Brickell may experience ownership changes in the future as a result of offerings of our stock or subsequent shifts in its stock ownership, some of which are outside of its control. In that case, the ability to use net operating loss carry-forwards to offset future taxable income will be limited following any such ownership change.

Brickell may be adversely affected by natural disasters and other catastrophic events and byman-made problems such as terrorism that could disrupt its business operations, and its business continuity and disaster recovery plans may not adequately protect it from a serious disaster.

Brickell’s corporate office is located in Boulder, Colorado, near a major flood and blizzard zone. If a disaster, power outage, computer hacking, or other event occurred that prevented Brickell from using all or a significant portion of an office, that damaged critical infrastructure, such as enterprise financial systems, IT systems, manufacturing resource planning or enterprise quality systems, or that otherwise disrupted operations, it may be difficult or, in certain cases, impossible for it to continue its business for a substantial period of time. Brickell’s contract manufacturer’s and suppliers’ facilities are located in multiple locations where other natural disasters or similar events, such as tornadoes, fires, explosions or large-scale accidents or power outages, or IT threats, could severely disrupt Brickell’s operations and have a material adverse effect on its business, financial condition, operating results and prospects. In addition, acts of terrorism and othergeo-political unrest could cause

53.

disruptions in Brickell’s business or the businesses of its partners, manufacturers or the economy as a whole. All of the aforementioned risks may be further increased if Brickell does not implement a disaster recovery plan or its partners’ or manufacturers’ disaster recovery plans prove to be inadequate. To the extent that any of the above should result in delays in the regulatory approval, manufacture, distribution or commercialization of sofpironium bromide, its business, financial condition, operating results and prospects would suffer.

Brickell’s business and operations would suffer in the event of system failures, cyber-attacks or a deficiency in its cyber-security.

Despite the implementation of security measures, Brickell’s internal computer systems and those of its current and future CROs and other contractors and consultants are vulnerable to damage from computer viruses, unauthorized access, natural disasters, terrorism, war and telecommunication and electrical failures. The risk of a security breach or disruption, particularly through cyber-attacks or cyber-intrusion, including by computer hackers, foreign governments, and cyber-terrorists, has generally increased as the number, intensity and sophistication of attempted attacks and intrusions from around the world have increased. While Brickell has not experienced any such material system failure, accident or security breach to date, if such an event were to occur and cause interruptions in Brickell’s operations, it could result in a material disruption of its development programs and its business operations. In addition, since Brickell sponsors clinical trials, any breach that compromises patient data and identities causing a breach of privacy could generate significant reputational damage and legal liabilities and costs to recover and repair, including affecting trust in the company to recruit for future clinical trials. For example, the loss of clinical trial data from completed or future clinical trials could result in delays in Brickell’s regulatory approval efforts and significantly increase its costs to recover or reproduce the data. To the extent that any disruption or security breach were to result in a loss of, or damage to, Brickell’s data or applications or inappropriate disclosure of confidential or proprietary information, Brickell could incur liability and the further development and commercialization of its products and product candidates could be delayed.

Risks Related To Brickell’s Intellectual Property

Brickell may not be able to obtain, maintain or enforce global patent rights or other intellectual property rights that cover sofpironium bromide and technologies that are of sufficient breadth to prevent third parties from competing against Brickell.

Brickell’s success with respect to sofpironium bromide will depend, in part, on its ability to obtain and maintain patent protection in both the United States and other countries, to preserve its trade secrets and to prevent third parties from infringing on its proprietary rights. Brickell’s ability to protect sofpironium bromide from unauthorized or infringing use by third parties depends in substantial part on its ability to obtain and maintain valid and enforceable patents around the world.

The patent application process, also known as patent prosecution, is expensive and time-consuming, and Brickell and its current or future licensors and licensees may not be able to prepare, file and prosecute all necessary or desirable patent applications at a reasonable cost or in a timely manner in all the countries that are desirable. It is also possible that Brickell or its current licensors, or any future licensors or licensees, will fail to identify patentable aspects of inventions made in the course of development and commercialization activities before it is too late to obtain patent protection on them. Therefore, these and any of Brickell’s patents and applications may not be prosecuted and enforced in a manner consistent with the best interests of its business. Moreover, Brickell’s competitors independently may develop equivalent knowledge, methods andknow-how or discover workarounds to Brickell patents that would not constitute infringement. Any of these outcomes could impair Brickell’s ability to enforce the exclusivity of its patents effectively, which may have an adverse impact on its business, financial condition and operating results.

Due to legal standards relating to patentability, validity, enforceability and claim scope of patents covering pharmaceutical inventions, Brickell’s ability to obtain, maintain and enforce patents is uncertain and involves

54.

complex legal and factual questions especially across countries. Accordingly, rights under any existing patents or any patents Brickell might obtain or license may not cover its product candidates or may not provide Brickell with sufficient protection for its product candidates to afford a sustainable commercial advantage against competitive products or processes, including those from branded, generic andover-the-counter pharmaceutical companies. In addition, Brickell cannot guarantee that any patents or other intellectual property rights will issue from any pending or future patent or other similar applications owned by or licensed to Brickell. Even if patents or other intellectual property rights have issued or will issue, Brickell cannot guarantee that the claims of these patents and other rights are or will be held valid or enforceable by the courts, through injunction or otherwise, or will provide Brickell with any significant protection against competitive products or otherwise be commercially valuable to Brickell in every country of commercial significance that Brickell may target.

Competitors in the field of dermatologic therapeutics have created a substantial amount of prior art, including scientific publications, posters, presentations, patents and patent applications and other public disclosures including on the Internet. Brickell’s ability to obtain and maintain valid and enforceable patents depends on whether the differences between its technology and the prior art allow its technology to be patentable over the prior art. Brickell does not have outstanding issued patents covering all of the recent developments in its technology and is unsure of the patent protection that it will be successful in obtaining, if any. Even if the patents do successfully issue, third parties may design around or challenge the validity, enforceability or scope of such issued patents or any other issued patents Brickell owns or licenses, which may result in such patents being narrowed, invalidated or held unenforceable. If the breadth or strength of protection provided by the patents Brickell holds or pursues with respect to its product candidates is challenged, it could dissuade companies from collaborating with Brickell to develop or threaten its ability to commercialize or finance its product candidates.

The laws of some foreign jurisdictions do not provide intellectual property rights to the same extent or duration as in the United States, and many companies have encountered significant difficulties in acquiring, maintaining, protecting, defending and especially enforcing such rights in foreign jurisdictions. If Brickell encounters such difficulties in protecting or are otherwise precluded from effectively protecting its intellectual property in foreign jurisdictions, its business prospects could be substantially harmed, especially internationally.

Patents have a limited lifespan. In the United States, the natural expiration of a patent is generally 20 years after it is filed, with patent term extensions granted in certain instances to compensate for part of the period in which the drug was under development and could not be commercialized while under the patent. Without patent protection for sofpironium bromide, it may be open to competition from generic versions of sofpironium bromide. The issued U.S. patents relating to sofpironium bromide run through 2031, including expected extensions just described. Brickell also filed a new composition of matter patent application in the United States that would provide expected coverage through 2040, if approved.

Proprietary trade secrets and unpatentedknow-how are also very important to Brickell’s business. Although Brickell has taken steps to protect its trade secrets and unpatentedknow-how by entering into confidentiality agreements with third parties, and intellectual property protection agreements with officers, directors, employees, and certain consultants and advisors, there can be no assurance that binding agreements will not be breached or enforced by courts, that Brickell would have adequate remedies for any breach, including injunctive and other equitable relief, or that its trade secrets and unpatentedknow-how will not otherwise become known, inadvertently disclosed by Brickell or its agents and representatives, or be independently discovered by its competitors. If trade secrets are independently discovered, Brickell would not be able to prevent their use and if Brickell and its agents or representatives inadvertently disclose trade secrets and/or unpatentedknow-how, Brickell may not be allowed to retrieve this and maintain the exclusivity it previously enjoyed.

Brickell may not be able to protect its intellectual property rights throughout the world.

Filing, prosecuting and defending patents on Brickell’s product candidates does not guarantee exclusivity. The requirements for patentability differ in certain countries, particularly developing countries. In addition, the

55.

laws of some foreign countries do not protect intellectual property rights to the same extent as laws in the United States, especially when it comes to granting use and other kinds of patents and what kind of enforcement rights will be allowed, especially injunctive relief in a civil infringement proceeding. Consequently, Brickell may not be able to prevent third parties from practicing its inventions in all countries outside the United States and even in launching an identical version of Brickell’s product notwithstanding Brickell has a valid patent in that country. Competitors may use Brickell’s technologies in jurisdictions where it has not obtained patent protection to develop their own products, or produce copy products, and, further, may export otherwise infringing products to territories where Brickell has patent protection but enforcement on infringing activities is inadequate or where Brickell has no patents. These products may compete with Brickell’s products, and Brickell’s patents or other intellectual property rights may not be effective or sufficient to prevent them from competing.

Many companies have encountered significant problems in protecting and defending intellectual property rights in foreign jurisdictions. The legal systems of certain countries, particularly certain developing countries, do not favor the enforcement of patents and other intellectual property protection, particularly those relating to pharmaceuticals, and the judicial and government systems are often corrupt, which could make it difficult for Brickell to stop the infringement of its patents or marketing of competing products in violation of its proprietary rights generally. Proceedings to enforce its patent rights in foreign jurisdictions could result in substantial costs and divert its efforts and attention from other aspects of its business, could put its global patents at risk of being invalidated or interpreted narrowly and its global patent applications at risk of not issuing, and could provoke third parties to assert claims against it. Brickell may not prevail in any lawsuits that Brickell initiates or infringement actions brought against Brickell, and the damages or other remedies awarded, if any, may not be commercially meaningful when Brickell is the plaintiff. When Brickell is the defendant it may be required to post large bonds to stay in the market while it defends itself from an infringement action.

In addition, certain countries in Europe and certain developing countries have compulsory licensing laws under which a patent owner may be compelled to grant licenses to third parties, especially if the patent owner does not enforce or use its patents over a protracted period of time. In some cases, the courts will force compulsory licenses on the patent holder even when finding the patent holder’s patents are valid if the court believes it is in the best interests of the country to have widespread access to an essential product covered by the patent. In these situations the royalty the court requires to be paid by the licenseholder receiving the compulsory license is not calculated at fair market value and can be inconsequential, thereby disaffecting the patentholder’s business. In these countries, Brickell may have limited remedies if its patents are infringed or if Brickell is compelled to grant a license to its patents to a third party, which could also materially diminish the value of those patents. This would limit its potential revenue opportunities. Accordingly, Brickell’s efforts to enforce its intellectual property rights around the world may be inadequate to obtain a significant commercial advantage from the intellectual property that Brickell owns or licenses, especially in comparison to what it enjoys from enforcing its intellectual property rights in the Unites States. Finally, the company’s ability to protect and enforce its intellectual property rights may be adversely affected by unforeseen changes in both U.S. and foreign intellectual property laws, or changes to the policies in various government agencies in these countries, including but not limited to the patent office issuing patents and the health agency issuing pharmaceutical product approvals For example, in Brazil, pharmaceutical patents require initial approval of the Brazilian health agency (ANVISA). Finally, many countries have large backlogs in patent prosecution, and in some countries in Latin America it can take years, even decades, just to get a pharmaceutical patent application reviewed notwithstanding the merits of the application.

Obtaining and maintaining Brickell’s patent protection depends on compliance with various procedural, document submission, fee payment, and other requirements imposed by governmental patent agencies, and its patent protection could be reduced or eliminated fornon-compliance with these requirements.

Periodic maintenance and annuity fees on any issued patent are due to be paid to the USPTO and foreign patent agencies in several stages over the lifetime of the patent. The USPTO and various foreign governmental patent agencies require compliance with a number of procedural, documentary, fee payment and other similar

56.

provisions during the patent application process. While an inadvertent lapse can, in many cases, be cured by payment of a late fee or by other means in accordance with the applicable rules, there are situations in which noncompliance can result in abandonment or lapse of the patent or patent application, resulting in partial or complete loss of patent rights in the relevant jurisdiction just for failure to know about and/or timely pay a prosecution fee.Non-compliance events that could result in abandonment or lapse of a patent or patent application include failure to respond to official actions within prescribed time limits,non-payment of fees in prescribed time periods, and failure to properly legalize and submit formal documents in the format and style the country requires. If Brickell or its licensors fail to maintain the patents and patent applications covering its product candidates for any reason, the company’s competitors might be able to enter the market, which would have an adverse effect on Brickell’s business.

If Brickell fails to comply with its obligations under its intellectual property license agreements, it could lose license rights that are important to its business. Additionally, these agreements may be subject to disagreement over contract interpretation, which could narrow the scope of its rights to the relevant intellectual property or technology, or increase its financial or other obligations to its licensors.

Brickell has entered intoin-license arrangements with respect to certain of its product candidates. These license agreements impose various diligence, milestone, royalty, insurance and other obligations on Brickell. If Brickell fails to comply with these obligations, the respective licensors may have the right to terminate the license, in which event Brickell may not be able to develop or market the affected product candidate. The loss of such rights could materially adversely affect its business, financial condition, operating results and prospects. For more information about these license arrangements, see “Description of Brickell’s Business—Collaborations andOut-License Agreements.”

Brickell’s commercial success depends on its ability to develop, manufacture, market and sell its product candidates and use its proprietary technologies without infringing the proprietary rights of third parties. Brickell cannot assure that marketing and selling such candidates and using such technologies will not infringe existing or future patents. Numerous U.S.- and foreign-issued patents and pending patent applications owned by third parties exist in the fields relating to its product candidates. As the biotechnology and pharmaceutical industries expand and more patents are issued, the risk increases that others may assert that its product candidates, technologies or methods of delivery or use infringe their patent rights. Moreover, it is not always clear to industry participants, including us, which patents and other intellectual property rights cover various drugs, biologics, drug delivery systems or their methods of use, and which of these patents may be valid and enforceable. Thus, because of the large number of patents issued and patent applications filed in Brickell’s fields across many countries, there may be a risk that third parties may allege they have patent rights encompassing Brickell’s product candidates, technologies or methods.

In addition, there may be issued patents of third parties that are infringed or are alleged to be infringed by Brickell’s product candidates or proprietary technologies notwithstanding patents Brickell may possess. Because some patent applications in the United States may be maintained in secrecy until the patents are issued, because patent applications in the United States and many foreign jurisdictions are typically not published until 18 months after filing and because publications in the scientific literature often lag behind actual discoveries, Brickell cannot be certain that others have not filed patent applications for technology covered by its own andin-licensed issued patents or its pending applications. Brickell’s competitors may have filed, and may in the future file, patent applications covering Brickell’s own product candidates or technology similar to Brickell’s technology. Any such patent application may have priority over Brickell’s own andin-licensed patent applications or patents, which could further require Brickell to obtain rights to issued patents covering such technologies, which may mean paying significant licensing fees or the like. If another party has filed a U.S. patent application on inventions similar to those owned orin-licensed to us, Brickell or, in the case ofin-licensed technology, the licensor may have to participate, in the United States, in an interference proceeding to determine priority of invention.

57.

Brickell may be exposed to, or threatened with, future litigation by third parties having patent or other intellectual property rights alleging that its product candidates or proprietary technologies infringe such third parties’ intellectual property rights, including litigation resulting from filing under Paragraph IV of the Hatch-Waxman Act or other countries’ laws similar to the Hatch-Waxman Act. These lawsuits could claim that there are existing patent rights for such drug, and this type of litigation can be costly and could adversely affect its operating results and divert the attention of managerial and technical personnel, even if Brickell does not infringe such patents or the patents asserted against Brickell is ultimately established as invalid. There is a risk that a court would decide that Brickell is infringing the third party’s patents and would order Brickell to stop the activities covered by the patents. In addition, there is a risk that a court will order Brickell to pay the other party significant damages for having violated the other party’s patents.

Because Brickell relies on certain third-party licensors and partners and will continue to do so in the future, if one of its licensors or partners is sued for infringing a third party’s intellectual property rights, Brickell’s business, financial condition, operating results and prospects could suffer in the same manner as if Brickell were sued directly. In addition to facing litigation risks, Brickell has agreed to indemnify certain third-party licensors and partners against claims of infringement caused by Brickell’s proprietary technologies, and Brickell has entered or may enter into cost-sharing agreements with some its licensors and partners that could require Brickell to pay some of the costs of patent litigation brought against those third parties whether or not the alleged infringement is caused by its proprietary technologies. In certain instances, these cost-sharing agreements could also require Brickell to assume greater responsibility for infringement damages than would be assumed just on the basis of its technology.

The occurrence of any of the foregoing could adversely affect Brickell’s business, financial condition or operating results.

Brickell may be subject to claims that its officers, directors, employees, consultants or independent contractors have wrongfully used or disclosed to Brickell alleged trade secrets of their former employers or their former or current customers.

As is common in the biotechnology and pharmaceutical industries, certain of Brickell’s employees were formerly employed by other biotechnology or pharmaceutical companies, including its competitors or potential competitors. Moreover, Brickell engages the services of consultants to assist Brickell in the development of Brickell’s products and product candidates, many of whom were previously employed at, or may have previously been or are currently providing consulting services to, other biotechnology or pharmaceutical companies, including its competitors or potential competitors. Brickell may be subject to claims that these employees and consultants or Brickell has inadvertently or otherwise used or disclosed trade secrets or other proprietary information of their former employers or their former or current customers. Although Brickell has no knowledge of any such claims being alleged to date, if such claims were to arise, litigation may be necessary to defend against any such claims. Even if Brickell is successful in defending against any such claims, any such litigation could be protracted, expensive, a distraction to its management team, not viewed favorably by investors and other third parties, and may potentially result in an unfavorable outcome.

The Special Meeting of Vical stockholders will be held on August 30, 2019, commencing at 8:00 a.m. local time, at Cooley LLP, 4401 Eastgate Mall, San Diego, California 92121. Vical is sending this proxy statement to its stockholders in connection with the solicitation of proxies by Vical’s board of directors for use at the Special Meeting and any adjournments or postponements of the Special Meeting. This proxy statement is first being furnished to stockholders of Vical on or about July 15, 2019.

Purposes of the Special Meeting

The purposes of the Special Meeting are:

To consider and vote upon a proposal to approve an amendment to Vical’s restated certificate of incorporation, as amended, to effect a reverse split of Vical’s common stock (the “Reverse Split”) at a ratio in the range of1-for-5 to1-for-15, inclusive, with such ratio to be mutually agreed to by Vical and Brickell and to be effected by Vical prior to the effective time of the Merger;

To consider and vote upon a proposal to approve the consummation of a change of control of Vical resulting from the Contemplated Transactions pursuant to the Nasdaq rules, as contemplated by the Merger Agreement (a copy of which is attached as Appendix A to this proxy statement); and

Recommendation of the Vical Board of Directors

•

The Vical board of directors has determined and believes that it is advisable to, and in the best interests of, Vical and its stockholders to approve the amendment to Vical’s restated certificate of incorporation, as amended, to effect the Reverse Split, as described in this proxy statement. Vical’s board of directors recommends that Vical stockholders vote “FOR” Proposal No. 1 to approve Vical effecting the Reverse Split.

•

The Vical board of directors has determined and believes that it is fair to, advisable and in the best interests of, Vical and its stockholders to approve the consummation of a change of control of Vical resulting from the Contemplated Transactions pursuant to the Nasdaq rules, as contemplated by the Merger Agreement. Vical’s board of directors recommends that Vical stockholders vote “FOR” Proposal No. 2 to approve of the consummation of the change of control of Vical resulting from the Contemplated Transactions pursuant to the Nasdaq rules, as contemplated by the Merger Agreement.

•

The Vical board of directors has determined and believes that it is advisable to, and in the best interests of, Vical and its stockholders to approve postponing or adjourning the Special Meeting, if necessary, to solicit additional proxies if there are not sufficient votes in favor of Proposal Nos. 1 or 2. Vical’s board of directors recommends that Vical stockholders vote “FOR” Proposal No. 3 to approve of postponing or adjourning the Special Meeting, if necessary, to solicit additional proxies if there are not sufficient votes in favor of Proposal Nos. 1 or 2.

Record Date and Voting Power

Only holders of record of Vical common stock at the close of business on the record date, July 2, 2019, are entitled to notice of, and to vote at, the Special Meeting. There were 125 holders of record of Vical common stock at the close of business on the record date. At the close of business on the record date, 22,841,278 shares of Vical common stock were issued and outstanding. Each share of Vical common stock entitles the holder thereof

61.

to one vote on each matter submitted for stockholder approval. See the section titled “Principal Stockholders of Vical” in this proxy statement for information regarding persons known to the management of Vical to be the beneficial owners of more than 5% of the outstanding shares of Vical common stock.

Voting and Revocation of Proxies

The proxy accompanying this proxy statement is being solicited on behalf of the board of directors of Vical for use at the Special Meeting.

If you are a stockholder of record of Vical as of the record date referred to above, you may vote in person at the Special Meeting or vote by proxy using the enclosed proxy card, over the telephone or via the Internet. Whether or not you plan to attend the Special Meeting, Vical urges you to vote by proxy to ensure your vote is counted. You may still attend the Special Meeting and vote in person if you have already voted by proxy. As a stockholder of record:

•

to vote in person, come to the Special Meeting and Vical will give you a ballot when you arrive.

•

to vote using the proxy card, simply mark, sign and date your proxy card and return it promptly in the postage-paid envelope provided.

•

to vote on the Internet, go to the website listed on your proxy card or voting instruction form to complete an electronic proxy card. You will be asked to provide the company number and control number from the enclosed proxy card.

•

to vote over the telephone, dial the toll-free phone number listed on a proxy card that may be delivered under the heading “Vote by Phone” and follow the recorded instructions.

If you vote by proxy, your vote must be received by 11:59 p.m. Eastern Time on August 29, 2019 to be counted.

If you are a beneficial owner and do not instruct your broker, bank, or other agent how to vote your shares, the question of whether your broker or nominee will still be able to vote your shares depends on whether the NYSE deems the particular proposal to be a “routine” matter. Brokers and nominees can use their discretion to vote “uninstructed” shares with respect to matters that are considered to be “routine,” but not with respect to “non-routine” matters. Proposal No. 2 (approval of the consummation of a change of control of Vical resulting from the Contemplated Transactions pursuant to the Nasdaq rules) is a non-routine matter, and accordingly your broker or nominee may not vote your shares on such proposals without your instructions. Proposal No. 1 (approval of the Reverse Split) and Proposal No. 3 (approval of the adjournment of the Special Meeting, if necessary) are considered routine matters and accordingly your broker or nominee may vote your shares on such proposals in the absence of your instructions.

All properly executed proxies that are not revoked will be voted at the Special Meeting and at any adjournments or postponements of the Special Meeting in accordance with the instructions contained in the proxy. If a holder of Vical common stock executes and returns a proxy and does not specify otherwise, the shares represented by that proxy will be voted “FOR” Proposal No. 1 to approve the amendment to the restated certificate of incorporation, as amended, of Vical to effect the Reverse Split; FOR” Proposal No. 2 to approve the consummation of a change of control of Vical resulting from the Merger pursuant to the Nasdaq rules, as contemplated by the Merger Agreement; and “FOR” Proposal No. 3 to postpone or adjourn the Special Meeting, if necessary, to solicit additional proxies if there are not sufficient votes in favor of Proposal Nos. 1 or 2 in accordance with the recommendation of the Vical board of directors.

62.

record of Vical can attend the Special Meeting and vote in person. Attendance alone will not revoke a proxy. If a Vical stockholder of record or a stockholder who owns Vical shares in “street name” has instructed a broker to vote its shares of Vical common stock, the stockholder must follow directions received from its broker to change those instructions.

Required Vote

Approval of Proposal No. 1 requires the affirmative vote of the holders of a majority of the outstanding shares of Vical’s common stock outstanding as of the record date for the Special Meeting, assuming a quorum is present. Abstentions and broker non-votes will have the effect of a “NO” vote for Proposal No. 1. It is anticipated that Proposal No. 1 will be a discretionary proposal considered routine under the rules of the NYSE.

Approval of Proposal No. 2 requires the affirmative vote of a majority of the votes cast in person or by proxy at the Special Meeting, assuming a quorum is present. Abstentions and broker non-votes will be not be considered votes cast and will have no effect on the vote for Proposal No. 2. It is anticipated that Proposal No. 2 will be a non-discretionary proposal considered non-routine under the rules of the NYSE.

Approval of Proposal No. 3 requires the affirmative vote of a majority of the votes present in person or by proxy at the Special Meeting and entitled to vote. Abstentions and broker non-votes will be considered votes cast and have the effect of a “NO” vote for Proposal No. 3. It is anticipated that Proposal No. 3 will be a discretionary proposal considered routine under the rules of the NYSE.

Solicitation of Proxies

In addition to solicitation by mail, the directors, officers, employees and agents of Vical may solicit proxies from Vical stockholders by personal interview, telephone, telegram or otherwise. Alliance Advisors has been engaged to assist Vical with its stockholder engagement process, and Vical may pay Alliance Advisors a customary fee of $10,000, plus reasonableout-of-pocket expenses, in connection with the solicitation. Vical will reimburse these brokers, custodians, nominees and fiduciaries for the reasonableout-of-pocket expenses they incur in connection with the forwarding of solicitation materials.

Other Matters

As of the date of this proxy statement, Vical’s board of directors does not know of any business to be presented at the Special Meeting other than as set forth in the notice accompanying this proxy statement. If any other matters should properly come before the Special Meeting, it is intended that the shares represented by proxies will be voted with respect to such matters in accordance with the judgment of the persons voting the proxies.

63.

THE MERGER

This section and the section titled “The Merger Agreement” in this proxy statement describe the material aspects of the Merger, including the Merger Agreement. While Vical and Brickell believe that this description covers the material terms of the Merger and the Merger Agreement, it may not contain all of the information that is important to you. You should read carefully this entire proxy statement for a more complete understanding of the Merger and the Merger Agreement, including the Merger Agreement attached as Appendix A, the opinion of MTS Securities attached as Appendix B, and the other documents to which you are referred herein. See the section titled “Where You Can Find More Information” in this proxy statement.

Background of the Merger

Vical’s board of directors and management regularly review Vical’s operating and strategic plans, both near-term and long-term, as well as potential strategic options in an effort to enhance stockholder value. These reviews and discussions focus, among other things, on the opportunities and risks associated with Vical’s business and financial condition and strategic relationships and other strategic options.

On January 22, 2018, we and Astellas Pharma, Inc. (“Astellas”) announced that ASP0113, an investigational DNA vaccine being developed for cytomegalovirus-seropositive hematopoietic stem cell transplant recipients, did not meet its primary and secondary endpoints in the Phase 3 HELIOS clinical trial.

On January 30, 2018, we announced that we were undertaking a restructuring in order to conserve capital and focus our efforts onVL-2397, our antifungal drug product candidate that was then entering a pivotal Phase 2 clinical trial, and on completing the Phase 2 study of our bivalent vaccine candidate for herpes simplex virus type 2(“HSV-2”). The restructuring included a reduction in staff of 54% and the termination of all activities related to the ASP0113 program licensed to Astellas.

On February 20, 2018, we announced the initiation of a Phase 2 trial of theVL-2397 novel antifungal compound.

On March 9, 2018, our board of directors held a regularin-person meeting, with representatives of management and Cooley LLP (“Cooley”), outside counsel to Vical, also attending. At this meeting, and in anticipation of the strategic options to be considered following the results of theHSV-2 Phase 2 clinical trial, representatives of MTS were invited to make a presentation on Vical’s strategic alternatives, including a reverse merger, strategic merger,out-licensing of Vical’s assets and remaining as an independent company. MTS was asked to participate in the meeting based upon its experience and our management and board’s prior familiarity with them, which included past, informal advice on potential product and other opportunities.

On June 11, 2018, we announced that the Phase 2 study of our bivalent vaccine candidate forHSV-2 did not meet its primary endpoint of annualized lesion recurrence rate calculated based on those genital recurrences that were both clinically and virologically confirmed during a minimum of nine months of surveillance, and that as a result, we were terminating theHSV-2 program.

On June 18, 2018, our board held a regularin-person meeting, with representatives of management and Cooley attending, at which it considered potential strategic options, including a reverse merger, strategic merger and remaining as an independent company. At this meeting, our board approved the formation of a strategy committee comprised of Richard M. Beleson, Gary A. Lyons and George J. Morrow to assist Vical management in the strategic review. Our board also authorized Vical management to finalize and execute an engagement letter with MTS to act as a financial advisor in connection with the strategic review process. MTS was selected based upon our management and board’s familiarity with them, and, among other things, its knowledge and experience as a transaction advisor for mergers and acquisitions in the biopharmaceutical industry.

On July 16, 2018, we entered into an engagement letter with MTS.

64.

On July 19, 2018, we issued a press release announcing that our board planned to explore a range of strategic options to enhance stockholder value, and that it had retained MTS as its financial advisor to assist in the strategic review process.

Following the initiation of the strategic review, from a universe of approximately 500 companies, Vical management and MTS developed a list of more than 50 life sciences companies that were targeted for proactive outreach. Vical management and MTS focused on candidates with certain characteristics, including therapeutic area, caliber of management, science, differentiated drug pipelines and meaningful catalysts to achieve value appreciation within 12 to 24 months using Vical’s cash contribution, in addition to the counterparty’s own cash, without requiring further significant post-transaction dilution to Vical’s stockholders. While not a requirement, we also gave preference in our assessment to any counterparty that planned to continue development of ourVL-2397 program following the transaction (the foregoing two sentences, the “Determination Criteria”). The list was reviewed and approved by the strategy committee.

Following the July 19, 2018 press release through August 2018, MTS and Vical management began reaching out to potential counterparties. Of the more than 70 private and public companies contacted in 2018 by MTS and Vical management during this outreach process (including in response to inbound inquiries), 14 companies were selected to receive process letters, including Company A and Company B, private companies, and Company D, a public company, based on the Determination Criteria, with process letters being sent starting on August 21, 2018. The majority of process letters set a deadline of September 14, 2018 for the submission of proposals, though some parties who expressed interest later in the process received process letters with later submission deadlines. Of these 14 companies, six declined to submit a proposal. The remaining eight companies, plus two companies that did not receive process letters—Company C (a public company) and one other public company—submitted proposals. Of these 10 companies, nine executed confidentiality agreements and all 10 submitted formal proposals, which were then narrowed down to three companies following deliberation based on the Determination Criteria, and further due diligence, including scientific due diligence. All of the confidentiality agreements executed in this phase of the process, including those with Company A, Company B, Company C and Company D, included a standstill provision that did not have a fall-away provision but permitted the counterparty to privately and confidentially approach our management during the standstill period.

On August 7, 2018, representatives of MTS reached out to Company D, a public company identified by MTS as a target for outreach, to provide an overview of the process. On August 16, 2018, we entered into a confidentiality agreement with Company D. On August 22, 2018, MTS sent Company D a process letter, following which representatives of Company D and Vical held an initial update call on September 12, 2018 and Company D was granted access to the Vical dataroom on September 14, 2018. On September 27, 2018, a representative of Company D sent an email communication to MTS indicating that they would not be submitting an offer for Vical because they were not interested in theVL-2397 program.

On August 9, 2018, we entered into a confidentiality agreement (which contained a standstill) with Company B, a private company interested in a reverse merger transaction with which Vical management had, prior to launching the strategic review process, discussed potential complementarity between the two companies.

On that same day, Company A, a private company interested in a reverse merger transaction with which Vical management had had preliminary discussions, sent MTS a preliminary,non-binding indication of interest that reflected a 60% and 40% ownership split for Company A and Vical stockholders in the post-closing company, assuming a Vical net cash balance of $40 million.

On August 15, 2018, we entered into a confidentiality agreement (which contained a standstill) with Company A.

From August 16, 2018 through March 25, 2019, the strategy committee met frequently with Vical management to discuss the status of the strategic review process.

65.

On August 22, 2018, we granted Company B access to our dataroom.

On August 29, 2018, we granted Company A access to our dataroom.

On September 10, 2018, Company A submitted an updated preliminarynon-binding indication of interest for a reverse merger transaction with Vical, which was consistent with its August 9, 2018 offer, including with respect to the equity split, but updated the projected Company A net cash balance.

On September 11, 2018, our board held a regularin-person meeting, with representatives of management, MTS and Cooley attending, to review the status of the strategic process, the proposal made by Company A and the potential counterparties remaining in the process, including Company A and Company B. At the meeting, a representative of Cooley reviewed the fiduciary duties of the board in the context of a strategic process.

On September 14, 2018, Company B submitted anon-binding offer for a reverse merger transaction with Vical. The proposal reflected a 62.5% and 37.5% ownership split for Company B and Vical stockholders in the post-closing company (using the treasury stock method (“TSM”)), subject to a net cash adjustment.

On October 24, 2018, MTS provided Vical’s written response to Company B’s initial proposal, which, among other things, countered with a 55% and 45% ownership split for Company B and Vical stockholders in the post-closing company (using TSM), without any exchange ratio adjustment for net cash (but subject to delivery of a minimum cash balance of approximately $40 million, depending on the timing of closing), as well as the issuance of a contingent value right (“CVR”) to Vical’s stockholders with respect to a pipeline product.

On October 25, 2018, MTS provided Vical’s written response to Company A’s initial proposal, which, among other things, countered with a 55% and 45% ownership split for Company A and Vical stockholders in the post-closing company (using TSM), subject to minimum Vical closing net cash balance at closing estimated to be $40 million, as well as either the issuance of a CVR or an upward adjustment in the equity split for Vical stockholders for any upfront or milestone payments with respect to any Vical partnering transactions with respect to a pipeline product.

On October 30, 2018, our board met in person with representatives of Company A and Company B to discuss each party’s business and proposal. Later that same day, with representatives of Cooley attending, the board discussed the status of negotiations with Company A and Company B. Management presented an overview of each potential counterparty’s business and an initial scientific due diligence assessment, as well an analysis of a scenario where Vical completed its Phase 2 clinical trial ofVL-2397 as a standalone company.

On October 30, 2018, we also entered into a confidentiality agreement (which contained a standstill) with Company C, a public company that was introduced to Vical by a representative of a Vical stockholder who was also a representative of a significant stockholder of Company C.

On October 30, 2018, we also received a counter-proposal from Company A, which, among other things, accepted Vical’s proposed ownership split, accepted Vical’s proposal on Vical net cash and a CVR or equity split adjustment to Vical stockholders for milestone and upfront payments to the extent that partnering transactions with respect to a pipeline product are entered into prior to closing.

In October and November 2018, our management conducted a due diligence review of Company A, Company B and Company C.

On November 1, 2018, Company C submitted a preliminarynon-binding proposal to acquire Vical in astock-for-stock transaction at a purchase price of $1.60 per share or $46.48 million, plus a CVR of $0.20 per share. At the direction of the strategy committee, a representative of Vical management contacted the Vical

66.

stockholder with a relationship with Company C, who in turn asked Company C to improve its proposal. On November 9, 2018, Company C updated its proposal to increase the purchase price to $1.80 per share, or $52.52 million, plus a CVR of $0.30 per share.

On November 7, 2018, Company B sent a counter-proposal to Vical which, among other things, reflected a 56.8% and 43.2% ownership split for Company B and Vical stockholders in the post-closing company (using TSM) and accepted Vical’s proposal that there be no exchange ratio adjustment for net cash (but subject to delivery of a minimum cash balance of $40 million (assuming no accrual of patients in the VL-2397 Phase 2 clinical trial)) and the issuance of a CVR to Vical stockholders.

On November 8, 2018, Company A sent a further revised counter-proposal to Vical, which proposed a 50% and 50% ownership split for Company A and Vical stockholders in the post-closing company (using TSM).

On November 28, 2018, our board held a special telephonic meeting, with representatives of management, MTS and Cooley attending, to discuss the strategic review process and Vical’s strategic options, including the status of discussions with Company A, Company B and Company C, as well as a potential liquidation scenario. Management provided a report on its assessment of the results of scientific due diligence on the companies remaining in the process. Management recommended that Vical not continue discussions with Company A because of issues identified in scientific due diligence, which in the board’s judgment did not justify its valuation, and concerns regarding the Company A management team. Vical management also recommended prioritizing the opportunity with Company C over Company B because of the strength of Company C’s pipeline, possibility of liquidity provided by Company C stock, and management’s assessment of the strengths of each company’s management team. The board considered certain risks associated with thestock-for-stock transaction proposed by Company C and directed MTS to continue discussions with Company C and develop a proposal for an exchange ratio collar. In addition, it directed MTS and Vical management to continue due diligence and discussions with Company B as a second option.

On December 4, 2018, MTS delivered Vical’s counter-proposal to Company C that reflected, among other things, a floating exchange ratio subject to a collar for a minimum and maximum Vical stockholder pro forma ownership of the combined company of 20% and 30%.

On December 4, 2018, Company C delivered its response to the Vical counter-proposal, which reflected a Vical stockholder ownership floor of 15% of the post-closing company, and a Vical net working capital purchase price adjustment based on a $40 million target. That same day, we granted Company C access to our dataroom. On December 5, 2018, representatives of MTS and Vical had a conference call with representatives of Company C to discuss how the Vical net working capital calculation and collar would be determined.

On December 6, 2018, Vical’s strategy committee met to discuss the revised terms proposed by Company C and the general status of discussions.

On December 8, 2018, representatives of Company C contacted representatives of MTS to inform them that because of, among other reasons, valuation concerns, volatility of their stock price and concerns about the adequacy of the parties’ net cash, it was not going to move forward with a potential transaction. In light of that development, Vical’s strategy committee directed management to continue to move forward with detailed due diligence and negotiations with Company B.

Our board held a regularin-person meeting on December 13, 2018, with representatives of management, Cooley and MTS attending, where members of management and representatives of MTS provided an update on negotiations with Company B and Company C, as well as ongoing due diligence efforts with respect to Company B. At this meeting, management discussed an analysis of a potential liquidation of Vical that had previously been provided to our board, including the potential timeline for liquidation and an estimate, subject to various assumptions, of the per share amount that would be distributable to Vical stockholders in this scenario.

67.

Following consideration of Vical’s alternatives, including concerns relating to the adequacy of Company B’s data raised in due diligence, as well as with Company B’s management, the board provided management with guidance regarding further discussions with Company B. At the meeting, a representative of Cooley reviewed the fiduciary duties of the board in the context of a strategic process.

On December 14, 2018, representatives of MTS sent a draft merger agreement to Company B and identified specific issues, from the Vical board, to be resolved prior to finalizing a transaction including the need to address concerns about Company B’s management team.

On January 17, 2019, a representative of the investment bank that had been engaged by Company B contacted MTS to inform them that they were withdrawing from the process because of, among other reasons, concerns about the adequacy of Vical’s net cash levels.

On January 28, 2019, representatives of Brickell communicated with MTS to inquire about the status of the process. From January28-31, 2019, there was a series of communications to provide MTS and Vical with information on Brickell new management hires and Brickell’s current financing process with various parties.

On January 29, 2019, our board held a special telephonic meeting, with representatives of management, Cooley and MTS attending, where members of management and representatives of MTS provided an update on the strategic process and Vical’s strategic options, including liquidation of the company, as previously presented to the board. In addition, the board discussed the status of theVL-2397 Phase 2 clinical trial, including patient accrual rates, and Vical’s cash burn and cash position. The board directed management to explore a potentialsub-license or other transaction related to the disposition of theVL-2397 program and to otherwise prepare to cease further development ofVL-2397 in light of the low patient accrual rates in the study.

Following the January 29, 2019 board meeting, MTS continued reaching out to potential counterparties for a second round of the strategic review process. Of the 39 private and public companies that were targets of outreach during the second phase of the process (including in response to inbound inquiries), and based on the Determination Criteria (other than the counterparties’ willingness to continue theVL-2397 program), Vical management selected 10 companies, including Brickell and Company D, to receive process letters starting on February 11, 2019. The majority of the process letters set a deadline of February 25, 2019 for submission of a proposal, though some parties who expressed interest later received process letters with later submission deadlines. Nine of the 10 companies that received process letters submitted a formal proposal, along with one additional company that made an inbound inquiry and did not receive a process letter. Of those remaining 10 companies that submitted formal proposals, nine executed confidentiality agreements. All of the confidentiality agreements executed with parties active in this phase of the process, including by Company D and Brickell, included a standstill provision but permitted the counterparty to privately and confidentially approach our management during the standstill period. Three of the nine confidentiality agreements with parties other than Company D and Brickell had fall-away provisions.

On February 1, 2019, representatives of MTS and Brickell had a call to discuss strategic process overview and timing.

On February 4, 2019, Vical entered into a confidentiality agreement (which contained a standstill and was dated to be effective as of January 31, 2019) with Brickell and granted Brickell dataroom access. On February 5, 2019, Vical received access to Brickell’s dataroom.

On February 11, 2019, Brickell made a management presentation to Vical. That same day, MTS sent a process letter to Brickell.

On February 12, 2019, representatives of MTS and Brickell held a call to discuss timing, key issues and key considerations for a proposal.

68.

On February 18, 2019, the Vical board held a special telephonic meeting, with representatives of management, MTS and Cooley attending. At this meeting MTS provided an update on the strategic review process, including the current opportunities, the status of discussions with potential counterparties and strategies for soliciting additional proposals. Our board discussed the relative merits of the opportunities under consideration with Brickell and three other private companies, which management presented to the board as its highest priority opportunities based on the Determination Criteria (other than the counterparties’ willingness to continue theVL-2397 program), as well as opportunities with two public companies and one other private company. The board also discussed a potential liquidation of the company, as previously presented to the board. The board directed Vical management to continue pursuing potential transactions that would generate maximum value for the company’s stockholders and to present such proposals at the next scheduled board meeting. The board also directed management to discontinue clinical development ofVL-2397, because of low patient accrual rates in the study, and to implement further cost reduction measures.

On February 19, 2019, we announced that we had decided to discontinue our Phase 2 clinical trial ofVL-2397 because of low patient accrual rates in the study and in order to conserve our cash resources while we pursued the strategic alternative review process.

Both prior to and following the termination of theVL-2397 program, our management pursued a number of potentialout-licensing transactions with respect to theVL-2397 assets but none of the potential counterparties expressed any meaningful interest in the asset.

On February 21, 2019, representatives of Company D contacted MTS to inquire about the status of the strategic review process. Representatives of MTS had an update call with Company D on February 22, 2019.

On February 25, 2019, Brickell submitted a preliminarynon-binding indication of interest concerning a reverse merger transaction with Vical. The proposal reflected a 60% and 40% ownership split for Brickell and Vical stockholders in the post-closing company based on a $100 million pro forma valuation, a seven-member post-closing board of directors (with two Vical directors) and a minimum Vical net cash balance of $35 million at closing, and it also summarized the terms of a proposed concurrent financing with an affiliate of NovaQuest Capital Management (“NovaQuest”) for $25 million ofnon-dilutiveat-risk product financing and $5 million in equity. Brickell’s belief was that the funding from NovaQuest, along with Vical net cash, would provide sufficient financial resources, through the fourth quarter of 2020 to allow the combined company to focus on the development and potential commercialization of its sofpironium bromide program for the treatment of axillary hyperhidrosis.

On March 4, 2019, the Vical strategy committee discussed the Brickell proposal with representatives of MTS. Following this discussion, MTS contacted Brickell to indicate that Brickell was going to advance in the process and to counter with a 56.4% and 43.6% ownership split for Brickell and Vical stockholders in the post-closing company (on a TSM basis).

On March 5, 2019, MTS sent an illustrative pro forma capitalization table to Brickell and the parties followed up with a call to discuss the proposed valuation splits.

On March 6, 2019, Brickell sent MTS its executed term sheet with NovaQuest to address the Vical management teams’ need for a high level of certainty with respect to Brickell’s post-transaction financial resources, which was consistent with the terms summarized in Brickell’s indication of interest, as well as the pivotal Phase 3 results for sofpironium bromide reported by Brickell’s development partner, Kaken, in Japan. In that same communication, Brickell rejected the ownership split that Vical had previously proposed and reacted to its previously proposed equity split.

On March 7, 2019, Company D submitted a writtennon-binding proposal to acquire Vical for Company D publicly traded shares valued at approximately $35 million. Following receipt of the proposal, representatives of

69.

MTS and Company D discussed the methodology used to determine the valuation of the Company D share consideration.

On March 8, 2019, our board held a regularin-person meeting, with representatives of management and MTS attending, to review the 10 proposals submitted in response to the second outreach effort. At the meeting, management presented its assessment of the potential opportunities, classifying proposals by Company D, Brickell, two other public companies and three other private companies as prioritized opportunities based on the Determination Criteria (other than the counterparties’ willingness to continue theVL-2397 program). Management also presented its analysis of the prioritized opportunities based on factors including deal quality, cash at closing, management team quality, science and data quality, regulatory path and market potential. Based on these criteria, management recommended continuing the process with Company D, Brickell and one other public company. After further discussion of the opportunities in light of the Determination Criteria, the board directed management to continue discussions with Company D and Brickell and to disengage the other companies identified as prioritized opportunities.

Following the board meeting, representatives of MTS contacted Company D to propose a purchase price of the greater of $35 million of Company D shares or a number of Company D shares representing a specified minimum percentage of the post-closing company. Representatives of MTS also held a call with Brickell to convey that Brickell was a finalist subject to several key conditions, including entering into a definitive agreement for a concurrent financing with NovaQuest (the “Concurrent Financing”) at signing on terms reasonably satisfactory to Vical.

On March 12, 2019, representatives of Brickell met with our board of directors to present an overview of the company, respond to questions and discuss the current proposal.

On March 16, 2019, MTS sent a draft form of merger agreement to Brickell. The draft did not include an exchange ratio adjustment for net cash, but did include a closing condition for minimum Vical net cash in an amount to be determined.

On March 18, 2019, representatives of Company D held a call with our board to present an overview of the company, respond to questions and discuss the current proposal. That same day Vicalre-opened its dataroom to Company D.

On March 19, 2019, representatives of Brickell held a call with our management team to discuss financial due diligence matters.

On March 20, 2019, Company D sent MTS a counter-proposal that increased the Vical valuation to $40 million, payable in Company D stock, and proposed a collar of plus or minus 25% of the price per share as of the signing date.

On March 25, 2019, representatives of Brickell circulated a revised draft of the merger agreement to MTS. The draft proposed an exchange ratio adjustment for each party’s net cash and a minimum Vical net cash closing condition (and corresponding Brickell termination right) of $30 million.

On March 27, 2019, Cooley and Mayer Brown LLP (“Mayer Brown”), outside counsel to Brickell, held a call to discuss Cooley’s initial questions on the revised draft of the merger agreement. That same day, members of Vical management met with representatives of Brickell to discuss the status of the transaction and Vical’s pending due diligence inquiries.

On March 29, 2019, Company D sent MTS a further updated proposal, which provided for a purchase price of $40 million above a certain share price and $35 million below a certain share price, with each party having termination right if the share price fell below a certain threshold.

70.

On April 2, 2019, Company D held a due diligence call and MTS submitted a request for additional financial information. Following discussion of the share price threshold at which the parties would have the right to terminate, Company D followed up with MTS to propose a revised threshold for a termination right if the share price fell below a certain threshold. That same day, representatives of Vical, MTS and Brickell held a call to discuss Brickell’s cash flow and balance sheet.

On April 3, 2019, Cooley circulated a revised draft of the merger agreement to Mayer Brown. The draft noted Vical’s expectation that the Concurrent Financing would be committed at signing and proposed an exchange ratio adjustment and mutual closing conditions based on minimum levels of net cash.

On April 4, 2019, representatives of MTS, Vical and NovaQuest held a call to discuss the terms of the proposed Concurrent Financing and respond to due diligence questions.

On April 8, 2019, MTS sent a counter-proposal to Company D, which added a 10% ownership floor for Vical stockholders in the post-closing company and proposed that there should be a linear increase in Vical stockholder implied equity value in the case of a Company D closing share price drop relative to the reference share price at signing. Company D rejected the proposed ownership floor but accepted the linear equity value gradient proposal.

On April 9, 2019, Mayer Brown circulated a revised draft of the merger agreement to Cooley and conveyed Brickell’s request to enter into exclusivity with Vical in order to finalize the transaction documents.

On April 10, 2019, MTS sent a form of merger agreement to Company D.

On April 11, 2019, Company D sent a draft exclusivity letter to MTS.

On April 15, 2019, our board held a special telephonic meeting, with representatives of management, MTS and Cooley attending, to review the status of discussions with Brickell and Company D and update the board on the terms proposed by each party. Management reviewed preliminary due diligence results and the strengths and weaknesses of Brickell and Company D. The board discussed an upcoming regulatory milestone of Company D and management’s recommended approach to moving forward with the strategic process depending on this regulatory outcome. It also discussed the anticipated timing for finalizing the Concurrent Financing for Brickell relative to the timing of certain regulatory matters with respect to Company D. Following discussion, our board directed management to defer the decision on whether to enter into exclusivity with either counterparty until further clarity was gained regarding the regulatory matters.

On April 17, 2019, Company D sent an updated exclusivity letter and a draft form of merger agreement to MTS.

On April 26, 2019, representatives of MTS, Vical management and Company D held a call to clarify certain terms in the merger agreement, including termination rights associated with Company D’s stock price and Vical stockholder ownership thresholds in the post-closing company. That same day MTS sent a revised draft of the exclusivity letter to Company D and a markup of Company D’s indication of interest.

On May 1, 2019, representatives of Vical, Company D and MTS held a call to discuss certain regulatory developments at Company D.

On May 3, 2019, our board of directors held a special telephonic meeting, with representatives of management, Cooley and MTS attending, to review the impact of certain negative regulatory developments at Company D on the strategic review process. Management reviewed the status of negotiations with Brickell, including updates on transaction terms, the status of Brickell’s Concurrent Financing and key items to be completed in order to finalize a transaction. The board discussed Vical’s options, including moving forward with

71.

Brickell or liquidating the company, as previously presented to the board. In view of the negative regulatory outcome and resulting decline in Company D’s stock price, the board directed management to end discussions with Company D and enter into a15-day exclusivity period with Brickell. The board also discussed the other companies that were still in the process and determined that they were not viable candidates based upon the Determination Criteria. That same day, representatives of MTS sent Brickell a draft exclusivity agreement.

On May 6, 2019, we executed an exclusivity agreement with Brickell, which provided for an exclusivity period through the end of May 22, 2019.

On May 7, 2019, MTS sent Brickell an updated pro forma capitalization table. That same day representatives of Cooley, Mayer Brown, Brickell and Vical held a call to discuss the treatment of various Brickell securities in calculating the Exchange Ratio.

On May 9, 2019, Cooley circulated a revised draft of the merger agreement to Mayer Brown.

On May 10, 2019, Brickell sent MTS the then-current draft of the Funding Agreement with respect to the Concurrent Financing, together with a summary of transaction terms, which added the issuance of the NovaQuest Warrants and removed the $5 million of preferred equity financing that was included in the NovaQuest initial term sheet.

On May 13, 2019, Brickell sent MTS a draft of the form of NovaQuest Warrants.

On May 14, 2019, representatives of Vical, MTS and Brickell had a call to discuss the terms of the Funding Agreement and NovaQuest Warrants.

On May 15, 2019, Mayer Brown sent a revised draft of the merger agreement to Cooley, which, among other things, proposed a closing condition for minimum Brickell net working capital and proposed a termination fee in certain circumstances of $1.5 million. That same day Mayer Brown and Cooley held a call to discuss treatment of Brickell equity awards in the transaction.

On May 19, 2019, representatives of Brickell circulated a revised draft of the Funding Agreement to Vical and Cooley. That same day, Cooley sent a revised draft of the merger agreement to Mayer Brown, which proposed a closing condition for a higher minimum Brickell net working capital. The draft also added Vical termination rights and a $1 million reverse termination fee payable to Vical in the event that the Concurrent Financing failed to close. The exchange ratio calculation was modified in the draft to include the recently proposed NovaQuest Warrants in the fully-diluted Brickell outstanding share count despite being proposed to be issued by Vical following the transaction.

On May 20, 2019, Mayer Brown sent a revised draft of the merger agreement to Cooley. Representatives of Cooley, Mayer Brown, Vical and Brickell held a call to discuss feedback on the draft Funding Agreement and NovaQuest Warrants. Later that day, Cooley circulated a revised draft of the merger agreement to Mayer Brown.

Between May 21, 2019 and June 2, 2019, Cooley and Mayer Brown exchanged drafts of the merger agreement, disclosure schedules to the merger agreement, support agreement,lock-up agreement and the Funding Agreement, and participated in calls to discuss the terms thereof. Among other provisions, the parties negotiated the inputs to the calculation of the Exchange Ratio (including the treatment of securities issued in thepre-closing period and the NovaQuest Warrants), the definition of Vical net cash, Brickell net working capital as well as the terms (including with respect to deal certainty) of the Funding Agreement. Brickell, based on further review of its commitments and in light of agreed upon changes to the definition of net working capital, which expanded the definition of included liabilities, requested a further reduction in the net working capital number for the purposes of the closing condition, and the parties ultimately agreed upon a net working capital closing condition.

72.

On June 2, 2019, at a special telephonic meeting with representatives of management, Cooley and MTS attending, our board in consultation with our management and representatives of MTS and Cooley reviewed the strategic process and Brickell’s proposal. At the meeting, representatives of MTS confirmed that MTS had not had any prior relationship with, or provided any services, to Brickell during the last two years. At this meeting, representatives of MTS also reviewed its financial analyses of the relative valuation of Vical and Brickell in the merger. Following discussion, MTS Securities provided an oral opinion (which was subsequently confirmed in writing as of June 2, 2019), as of the date of the MTS Opinion and subject to the various assumptions and limitations set forth therein the Exchange Ratio was fair, from a financial point of view, to the holders of Vical common stock. Also, at this meeting, representatives of MTS reviewed changes in the proposed terms of the merger agreement from those discussed at the May 3, 2019 board meeting, including the treatment of options and other Brickell securities issued during thepre-closing period in the Exchange Ratio, the terms of the Funding Agreement with NovaQuest and the closing condition for Brickell’s minimum level of net working capital at closing. Cooley reviewed the fiduciary duties of the board in the context of a strategic process and the merger agreement terms, including determination of the Exchange Ratio, conditions to closing, termination rights and fees associated with terminations under certain circumstances, and our limited right to continue negotiations with other interested parties. Our board engaged in extensive discussions relating to Brickell and the terms of the proposed transaction.

Following consideration of the Merger Agreement and the Contemplated Transactions, including consideration of the factors described below in the section titled “The Merger—Reasons for the Merger,” our board unanimously (a) determined that the Contemplated Transactions were fair to, advisable and in the best interests of Vical and its stockholders; (b) approved and declared advisable the merger agreement and the Contemplated Transactions, including the issuance of shares of Vical’s common stock to the shareholders of Brickell pursuant to the terms of the Merger Agreement; and (c) determined to recommend, upon the terms and subject to the conditions set forth in the Merger Agreement, that the stockholders of Vical vote to approve the Closing Stockholders Matters. Our board of directors also agreed to determine the final Vical board members and reverse stock split ratio at a later date.

Later that evening, representatives of Brickell, Vical and Merger Sub executed the definitive Merger Agreement. Concurrently with the execution of the Merger Agreement, each of the directors and executive officers of Brickell holding Brickell capital stock, as well as Brickell stockholders representing approximately 75% of Brickell’s outstanding common stock (on an as converted basis) as of such date entered into the support agreement and thelock-up agreement. That same day, Brickell entered into the Funding Agreement with NovaQuest.

Execution of the Merger Agreement was publicly announced before the open of markets on June 3, 2019.

On June 24, 2019, the Vical board received a written unsolicited offer from an investment firm and minority stockholder of Vical. The offer included a proposal to form a transaction vehicle to purchase, for cash, 100% of the Vical shares not owned by the bidder at a price of $1 per share. There were few details provided by the bidder, other than the indicated price and a proposal to enter into discussions. The offer did not include an actual funding (or other) commitment or a proposed definitive agreement.

On June 24, 2019, Vical provided Brickell with oral and written notice of the unsolicited offer as required pursuant to the Merger Agreement.

On June 27, 2019, at a special telephonic meeting with representatives of management, Cooley and MTS attending, Vical’s board reviewed and discussed the unsolicited offer. After carefully considering the offer, the Vical board rejected it based on several factors. First, the offer of $1.00 per share was significantly less than the $1.26 per share liquidation value of Vical assuming a liquidation date of July 31, 2019, which in turn was below the range of implied per share values to Vical stockholders in the pro forma combined company with Brickell, as more fully described below under the caption “The Merger—Opinion of MTS Securities, LLC”. Second, and of particular note, the board found that the offer was subject to substantial uncertainty, was inadequate and was not

73.

a Superior Offer (as defined in the section titled “The Merger Agreement—Non-Solicitation”) when compared to the potential long term value for Vical stockholders associated with the proposed merger with Brickell. Given these factors, the board determined that the proposal did not constitute and could not be reasonably likely to result in a Superior Offer (as defined in the section titled “The Merger Agreement—Non-Solicitation”). Accordingly, and consistent with its obligations under the Merger Agreement, Vical declined the request to enter into discussions with the bidder, and Vical communicated this decision to the bidder. The board continues to unanimously recommend that Vical stockholders vote to approve each of the proposals set forth in this proxy statement.

Reasons for the Merger

Following the Merger, the combined company will be a late clinical-stage company focused on the development and commercialization of differentiated therapeutics for the treatment of skin diseases. In concluding that the Merger is in the best interests of the Vical stockholders, Vical’s board of directors considered and viewed the following factors as supporting its decision to reach its conclusion (i) that the Merger and all related transactions set forth in and contemplated by the Merger Agreement are fair to, advisable and in the best interests of Vical and its stockholders and (ii) to approve and declare advisable the Merger Agreement and the Contemplated Transactions, and to recommend, upon the terms and subject to the conditions set forth in the Merger Agreement, that the stockholders of Vical vote to approve the Closing Stockholder Matters (as defined in the section titled “The Merger Agreement—Vical Special Meeting”):

•

The Vical board of directors and its financial advisors have undertaken a comprehensive and thorough process of reviewing and analyzing the potential merger transaction as well as reaching out to partnering candidates for a variety of strategic transactions, sincemid-2018, to identify the opportunity that would, in the Vical board of directors’ opinion, create the most value for Vical’s stockholders.

•

The Vical board of directors believes that, as a result of arm’s length negotiations with Brickell, Vical and its representatives negotiated the most favorable exchange ratio for Vical that Brickell was willing to agree to, and that the terms of the Merger Agreement include the most favorable terms to Vical in the aggregate to which Brickell was willing to agree.

•

The Vical board of directors believes, after a thorough review of strategic alternatives and Vical’s discussions with its financial advisors, legal counsel and third party experts in the field of dermatology, as well as Vical management’s discussions with Brickell’s senior management, that, compared to the Merger, no alternatives or other strategic options that may have been available to Vical, including remaining a standalone public company, were reasonably likely to create greater value for Vical’s stockholders.

•

The Vical board of directors believes, based in part on the judgment, advice and analysis of Vical’s management with respect to the potential strategic, financial and operational benefits of the Merger (which judgment, advice and analysis was informed in part by the business, scientific, technical, financial, accounting and legal due diligence investigation performed with respect to Brickell), that the combined company’s focus on development of dermatological therapeutics represents a sizeable market opportunity, may provide new medical benefits for many different patient populations, and may lead to partnering opportunities with third parties that previously were not available to Vical.

•

The Vical board of directors believes that the Merger would provide the existing Vical stockholders opportunities as a result of the Merger to participate in the value of Brickell’s current product candidate portfolio and in the prospective growth of the combined company given Brickell’s potential to commercialize its pipeline as supported by promising Phase 2 and Phase 3 (in one Japanese study completed by Brickell’s partner Kaken) clinical trial results for sofpironium bromide and a potential sizeable market opportunity in hyperhidrosis.

•

The Vical board of directors believes that the market for hyperhidrosis offers Brickell a sizeable commercial opportunity in addition to potential monetization of Vical’sVL-2397 program in the future.

74.

•

The Vical board of directors also reviewed, with Vical’s management and Brickell’s management, the current clinical plans of Brickell and believes, assuming the successful consummation of the Concurrent Financing, the combined company would have sufficient financial resources through the fourth quarter of 2020 to allow the management team to focus on the development and potential commercialization of the sofpironium bromide program for the treatment of axillary hyperhidrosis.

•

The Vical board of directors also considered that the combined company will be led by an experienced senior management team with a record of success in product commercialization and marketing and a board of directors with representation from both the current board of directors of Vical and of Brickell.

•

The Vical board of directors considered the financial analysis of MTS Securities, including the MTS Opinion, to Vical’s board of directors as to the fairness to Vical, from a financial point of view and as of the date of the MTS Opinion, of the aggregate number of shares of Vical common stock to be issued, or reserved for issuance, pursuant to the Contemplated Transactions, as more fully described below under the caption “The Merger—Opinion of MTS Securities, LLC”

•

The Vical board of directors considered MTS Securities’ analysis comparing the ranges of implied per share equity values to Vical stockholders in the pro forma combined company to the liquidation value of Vical, and the assessment that the per share liquidation value of Vical was below the range of implied per share values to Vical stockholders in the pro forma combined company, as more fully described below under the caption “The Merger—Opinion of MTS Securities, LLC”

The Vical board of directors also reviewed the recent financial condition and results of operations of Vical, including:

•

Vical’s lack of success in developing Vical’s product candidates;

•

Vical’s revenues over recent years has been largely dependent on manufacturing and research services performed under license agreements with third parties, which have been terminated, and Vical’s management team does not expect to receive any further payments under such license agreements;

•

the fact that Vical has discontinued all activities relating to development of its clinical programs, including its ASP0113 program collaboration with Astellas, itsHSV-2 vaccine program and itsVL-2397 Phase 2 clinical trial;

•

the risks associated with continuing to operate Vical on a standalone basis, including cash-burn;

•

the historic volatility of Vical’s common stock;

•

the consequences of current market conditions, the depressed stock price of Vical, continuing net operating losses, and the likelihood that the resulting circumstances for Vical, on a standalone basis, would not change for the benefit of the Vical stockholders in the foreseeable future;

•

the results of substantial efforts made over a significant period of time by Vical’s senior management and financial advisors to solicit strategic alternatives for Vical to the Merger, including the discussions that Vical management and the Vical board of directors had sincemid-2018 with other potential transaction candidates; and

•

Vical’s potential inability to maintain its Nasdaq listing without completing the Merger.

The Vical board of directors also reviewed the terms of the Merger and associated transactions, including:

•

the Exchange Ratio, which establishes the number of shares of Vical common stock to be issued in the Merger, is fixed based on the relative valuations of the companies (subject to adjustment based on the Vical Net Cash and Brickell Net Working Capital (each as defined in the section titled “The Merger Agreement—Conditions to the Completion of the Merger”)), and thus the relative percentage ownership of Vical stockholders and Brickell stockholders immediately following the completion of the Merger is similarly fixed;

75.

•

the limited number and nature of the conditions to Brickell’s obligation to consummate the Merger and the limited risk ofnon-satisfaction of such conditions as well as the likelihood that the Merger will be consummated on a timely basis;

•

the rights of, and limitations on, Vical under the Merger Agreement to consider certain unsolicited acquisition proposals under certain circumstances should Vical receive a superior offer;

•

the reasonableness of the potential termination fee of $1.0 million, which could become payable by either Vical or Brickell if the Merger Agreement is terminated in certain circumstances;

•

the execution of the Funding Agreement by Brickell and NovaQuest, pursuant to which NovaQuest committed to invest up to $25.0 million in research and development funding, with $5.6 million of the commitment expected to be paid promptly following the closing of the Merger and the remaining portion of the commitment expected to be paid in quarterly payments equal to of 67% of the forecasted research and development expenses to be incurred during each of the following four, or more, fiscal quarters; and

•

the belief that the terms of the Merger Agreement, including the parties’ representations, warranties and covenants, and the conditions to their respective obligations, are reasonable under the circumstances.

In the course of its deliberations, Vical’s board of directors also considered a variety of risks and other countervailing factors related to entering into the Merger, including:

•

the termination fee of $1.0 million payable to Brickell upon the occurrence of certain events and the potential effect of such termination fee in deterring other potential acquirers from proposing an alternative transaction that may be more advantageous to Vical’s stockholders;

•

the $25.0 million (plus interest) fee payable by Brickell to NovaQuest if the Funding Agreement is terminated in certain circumstances;

•

the substantial expenses to be incurred in connection with the Merger, including the costs associated with any related litigation;

•

the increased volatility, at least in the short term, of the trading price of the Vical common stock resulting from the Merger announcement;

•

the risk that the Merger might not be consummated in a timely manner or at all and the potential adverse effect of the public announcement of the Merger or on the delay or failure to complete the Merger on the reputation of Vical;

•

the risk that Brickell is unable to meet its closing condition to deliver a net working capital balance of at least -$11.5 million;

•

the risk that Vical is unable to meet its closing condition to deliver a net cash balance of at least $30 million;

•

the risk to Vical’s business, operations and financial results in the event that the Merger is not consummated, including the diminution of Vical’s cash and its likely inability to raise additional capital through the public or private sale of equity securities;

•

the strategic direction of the combined company following the completion of the Merger, which will be determined by the board of directors, the majority of the members which will initially be members of the current Brickell board of directors;

•

the risk that Brickell experiences delays or an inability to obtain FDA or foreign regulatory approval of sofpironium bromide;

•

the risk that the combined company is unsuccessful in developing and commercializing the combined company’s proposed product candidates or that future research and development activities may indicate that such product candidates are unsafe or ineffective;

76.

•

the risk that the combined company may never generate sufficient product revenue to become profitable;

•

the fact that the combined company may be unable to raise capital sufficient to fund its business activities and is otherwise unable to meet its ongoing financial obligations; and

•

various other risks associated with the combined company and the Merger, including those described in the section titled “Risk Factors” in this proxy statement.

The foregoing information and factors considered by the Vical board of directors are not intended to be exhaustive but are believed to include all of the material factors considered by Vical’s board of directors. In view of the wide variety of factors considered in connection with its evaluation of the Merger and the complexity of these matters, the Vical board of directors did not find it useful, and did not attempt, to quantify, rank or otherwise assign relative weights to these factors. In considering the factors described above, individual members of Vical’s board of directors may have given different weight to different factors. Vical’s board of directors conducted an overall analysis of the factors described above, including thorough discussions with, and questioning of, the Vical management team and the legal and financial advisors of Vical, and considered the factors overall to be favorable to, and to support, its determination.

Certain Vical Management Unaudited Prospective Financial Information

As a matter of course, Vical does not publicly disclose long-term projections of future financial results due to the inherent unpredictability and subjectivity of underlying assumptions and estimates. However, in connection with its evaluation of the Merger, the Vical board of directors considered certain unaudited,non-public financial projections with respect to Brickell as developed by Vical management, based on discussions with, and materials provided by, Brickell to Vical management on March 11, 2019 and March 14, 2019, industry metrics, product launches of products deemed similar to sofpironium bromide, and Vical management’s judgment, for each of the calendar years ending December 31, 2019 through 2034, which we refer to as the Vical management Brickell projections. The Vical management Brickell projections were provided to Vical’s financial advisor. A summary of the Vical management Brickell projections is set forth below.

The inclusion of the Vical management Brickell projections should not be deemed an admission or representation by Vical, its financial advisor or any of their respective officers, directors, affiliates, advisors, or other representatives with respect to such projections. The Vical management Brickell projections are not included to influence your views on the Merger but solely to provide stockholders access to certainnon-public information prepared by Vical management that was provided to the Vical board of directors in connection with its evaluation of the Merger and to Vical’s financial advisor to assist with its financial analyses as described in the section titled “The Merger—Opinion of MTS Securities, LLC” The information from the Vical management Brickell projections should be evaluated, if at all, in conjunction with the historical financial statements and other information regarding Vical and Brickell in this proxy statement.

The unaudited prospective financial information was not prepared with a view toward public disclosure, nor was it prepared with a view toward compliance with published guidelines of the SEC, the guidelines established by the American Institute of Certified Public Accountants for preparation and presentation of prospective financial information, or GAAP. Neither the independent registered public accounting firm of Vical, Brickell nor any other independent accountant has audited, reviewed, compiled, examined or performed any procedures with respect to the accompanying unaudited prospective financial information for the purpose of its inclusion herein, and accordingly, neither the independent registered public accounting firm of Vical, Brickell, nor any other independent accountant expresses an opinion or provides any form of assurance with respect thereto for the purpose of this proxy statement. The report of the independent registered public accounting firm of Vical contained in the Vical10-K is incorporated by reference into this proxy statement.

77.

The Vical management Brickell projections are prepared solely for internal use and in connection with Vical’s financial advisor’s work and are subjective in many respects. As a result, these Vical management Brickell projections are susceptible to multiple interpretations and periodic revisions based on actual experience and business developments. Although Vical believes its assumptions about Brickell to be reasonable, all financial projections are inherently uncertain, and Vical expects that differences will exist between actual and projected results. Although presented with numerical specificity, the Vical management Brickell projections reflect numerous variables, estimates, and assumptions made by Vical’s management at the time they were prepared, and also reflect general business, economic, market, and financial conditions and other matters, all of which are difficult to predict and many of which are beyond Vical’s control. In addition, the Vical management Brickell projections cover multiple years, and this information by its nature becomes subject to greater uncertainty with each successive year. Accordingly, there can be no assurance that the estimates and assumptions made in preparing the Vical management Brickell projections will prove accurate or that any of the Vical management Brickell projections will be realized.

The Vical management Brickell projections included certain assumptions relating to, among others things, Vical’s expectations, which may not prove to be accurate, based on information provided by Brickell relating to the axillary hyperhidrosis market in the United States and Japan and projected sofpironium bromide market share; expectations relating the timing of product launch, revenues and cost of goods sold; and expectations relating to operating expenses, working capital and capital expenditures. Vical derived net revenue for the United States based on: (i) the estimated market for axillary hyperhidrosis, which estimate were provided by Brickell through 2025 and extrapolated by Vical from 2026 to 2034, (ii) the estimated market share for sofpironium bromide, which was estimated by Vical by implying a peak market share for sofpironium bromide based on projections provided by Brickell and applying industry estimates and Vical management’s judgment for the launch curve to reach that peak market share, (iii) gross pricing assumptions, based on information provided by Brickell, adjusted for an estimated product launch in 2022 (as to which there can be no assurance), and(iv) gross-to-net sales assumptions, based on information provided by Brickell and adjusted by Vical from a conservative perspective. Vical estimated research and development expenditures prior to commercial launch based on projections provided by Brickell, adjusted for Vical’s expectations of timing for trial initiation and completion. Vical projected sales and marketing expenditures using on an estimated sales force size, based on information from Brickell management, and product launches of products deemed similar to sofpironium bromide, and applying industry estimates and Vical management’s judgment for sales representative costs and marketing expenditures. Vical projected general and administrative costs, assuming a substantial increase in expense leading up to commercial launch and then steady-state growth thereafter. Additionally, as appropriate, Vical incorporated the terms of existing licensing agreements and the Concurrent Financing. Working capital was projected based on industry metrics and Vical management’s judgment, adjusted as appropriate for the timing impacts of existing licensing agreements and the Concurrent Financing. Vical derived net revenue for Japan based upon a 90% cumulative probability of success with respect to the sofpironium bromide milestone and royalty payments in Japan that were provided by Brickell management for each of the calendar years ending December 31, 2019 through 2033 and extrapolated by Vical management for the calendar year ending December 31, 2034.

The Vical management Brickell projections are subject to many risks and uncertainties and you are urged to review the section titled “Risk Factors” beginning on page 25 of this proxy statement for a description of risk factors relating to the merger and Brickell’s business. You should also read the section titled “Cautionary NoteRegarding Forward-Looking Statements” beginning on page 59 of this proxy statement for additional information regarding the risks inherent in forward-looking information such as the Vical management Brickell projections. Vical management Brickell projections that were derived or extrapolated from projections provided by Brickell’s management were not reviewed or passed upon by Brickell management, its board of directors or its advisors.

The inclusion of the Vical management Brickell projections herein should not be regarded as an indication that Vical, its financial advisor or any of their respective affiliates or representatives considered or consider the

78.

Vical management Brickell projections to be necessarily indicative of actual future events, and the Vical management Brickell projections should not be relied upon as such. The Vical management Brickell projections do not take into account any circumstances or events occurring after the date they were prepared. Vical does not intend to, and disclaims any obligation to, update, correct, or otherwise revise the Vical management Brickell projections to reflect circumstances existing or arising after the date the Vical management Brickell projections were generated or to reflect the occurrence of future events, even in the event that any or all of the assumptions or other information underlying the Vical management Brickell projections are shown to be in error. Furthermore, the Vical management Brickell projections do not take into account the effect of any failure of the merger to be consummated and should not be viewed as accurate or continuing in that context.

The Vical management Brickell projections set forth below include Vical management calculated Brickell unlevered free cash flow, which is anon-GAAP measure. Due to the forward-looking nature of the Vical management Brickell projections, specific quantifications of the amounts that would be required to reconcile such projections to GAAP measures are not available. Vical believes that there is a degree of volatility with respect to certain GAAP measures, and certain adjustments made to arrive at the relevantnon-GAAP measures, which preclude Vical from providing accurate forecastednon-GAAP reconciliations. The statements set forth in this and the foregoing five paragraphs are referred to as “financial projection statements”.

In light of the foregoing factors and the uncertainties inherent in financial projections, stockholders are cautioned not to place undue reliance, if any, on the Vical management Brickell projections.

The following table, which is subject to the financial projection statements above, presents a selected summary of the unadjusted Vical management Brickell projections that were made available to the Vical board of directors and Vical’s financial advisor. As described above, the revenues and expenses in the following projections have been adjusted for an assumption of a cumulative probability of success for sofpironium bromide of 90% in Japan (as to which there can be no assurance).

Opinion of MTS Securities, LLC

Vical retained MTS as a financial advisor in connection with the Merger. On June 2, 2019, MTS Securities rendered its oral opinion to the Vical board of directors (which was subsequently confirmed in writing as of June 2, 2019), that, as of that date and subject to the various assumptions made, procedures followed, matters considered and qualifications and limitations set forth in such written opinion and described below, the Exchange Ratio in the Merger is fair, from a financial point of view, to the holders of Vical common stock (other than Excluded Shares). References to “Excluded Shares” in this section and for the purposes of the written opinion of MTS Securities refer to (i) shares of Vical capital stock that are held in treasury or by Brickell or Merger Sub immediately prior to the effective time of the Merger and (ii) any shares of Vical common stock held by a holder who is entitled to and properly demands appraisal rights in accordance with Section 262 of the Delaware General Corporation Law (the “DGCL”).

The full text of the written opinion of MTS Securities, which we refer to as the “MTS Opinion,” sets forth the assumptions made, procedures followed, matters considered and qualifications and limitations on the review undertaken by MTS Securities in connection with its opinion. The MTS Opinion is attached as Appendix B to this proxy statement and is incorporated herein by reference. The summary of the MTS Opinion set forth in this proxy statement is qualified in its entirety by reference to the full text of the MTS Opinion. We urge you to read carefully the MTS Opinion, together with the summary thereof in this proxy statement, in its entirety.

80.

MTS Securities provided its opinion for the information and assistance of the Vical board of directors in connection with its consideration of the Merger. The MTS Opinion addressed solely the fairness, from a financial point of view, of the Exchange Ratio, to the holders of Vical common stock in the Merger and does not address any other aspect or implication of the Merger. The MTS Opinion was not a recommendation to the Vical board of directors or any stockholder of Vical as to how to vote or to take any other action in connection with the Merger.

In the course of performing its review and analyses for rendering the opinion described above, MTS Securities:

(i)

reviewed the financial terms of a draft copy of the Merger Agreement as of May 31, 2019, which was the most recent draft available to MTS Securities prior to the time it rendered its oral opinion (the “Draft Merger Agreement”);

(ii)

reviewed certain publicly available business and financial information concerning Vical and Brickell and the industries in which Vical and Brickell each operate;

(iii)

reviewed certain internal financial analyses and forecasts prepared by and provided to us by the management of Vical relating to Vical’s and Brickell’s business (the “Projections”), and utilized per instruction of Vical;

(iv)

conducted discussions with members of senior management and representatives of each of Vical and Brickell concerning the matters described in clauses (ii) and (iii) above;

(v)

reviewed and analyzed the reported prices and trading history of shares of Vical common stock;

(vi)

reviewed and analyzed, based on the Projections, the projected cash flows to be generated by Brickell to determine the present value of Brickell’s discounted cash flows;

(vii)

compared certain publicly available financial and other information of certain publicly traded companies that MTS Securities deemed relevant;

(viii)

reviewed and analyzed certain financial terms of completed initial public offerings for certain companies that MTS Securities deemed relevant; and

(ix)

performed such other financial studies, analyses and investigations and considered such other information as MTS Securities deemed appropriate for the purposes of its opinion.

In arriving at its opinion, MTS Securities assumed and relied upon, without assuming liability or responsibility for independent verification, the accuracy and completeness of all of the financial, legal, regulatory, tax, accounting and other information that was publicly available or was provided to, discussed with or reviewed by MTS Securities and upon the assurances of the management of Vical and Brickell, respectively, that they were not aware of any material relevant developments or matters related to Vical or Brickell or that may affect the Merger that were omitted or that remained undisclosed to MTS Securities. The MTS Opinion does not address any legal, regulatory, tax, accounting or financial reporting matters, as to which MTS Securities understood that Vical had obtained such advice as it deemed necessary from other advisors, and MTS Securities relied, with the consent of the Vical board of directors, on any assessments made by such other advisors to Vical with respect to such matters. Without limiting the generality of the foregoing, with respect to the Projections, MTS Securities assumed, with the consent of the Vical board of directors, and based upon discussions with Vical’s management, that the Projections were reasonably prepared in good faith and that the Projections reflected the best currently available estimates and judgments of the management of Vical of the future results of operations and financial performance of Brickell. MTS Securities expressed no view as to the Projections or the assumptions on which they were based and MTS Securities assumes no responsibility for the accuracy or completeness thereof.

In arriving at its opinion, MTS Securities made no analysis of, and expressed no opinion as to, the adequacy of the reserves of Vical or Brickell. In addition, MTS Securities did not make any independent evaluations or

81.

appraisals of the assets or liabilities of Vical or Brickell or any of their respective subsidiaries, and was not furnished with any such evaluations or appraisals, nor did MTS Securities evaluate the solvency of Vical, Brickell or any other entity under any state or federal law relating to bankruptcy, insolvency or similar matters. MTS Securities assumed that there was no material change in the assets, financial condition, business or prospects of Vical or Brickell since the date of the most recent relevant financial information made available to MTS Securities. Without limiting the generality of the foregoing, MTS Securities undertook no independent analysis of any pending or threatened litigation, regulatory action, possible unasserted claims or other contingent liabilities to which Vical, Brickell or any of their respective affiliates is a party or may be subject, and, at the direction of Vical’s management and with the Vical board of directors’ consent, MTS Securities’ opinion made no assumption concerning, and therefore did not consider, the possible assertion of claims, outcomes or damages arising out of any such matters. MTS Securities also assumed that neither Vical nor Brickell is party to any material pending transaction that was not disclosed to MTS Securities, including, without limitation, any financing, recapitalization, acquisition or merger, divestiture orspin-off, other than the Merger, the Concurrent Financing, and transactions contemplated by the Note Purchase Agreement (as defined in the section titled “The Merger Agreement—Merger Consideration and Exchange Ratio—Exchange Ratio”). In addition, MTS Securities did not conduct, nor did it assume any obligation to conduct, any physical inspection of the properties or facilities of Vical or Brickell. MTS Securities assumed, at Vical’s direction and with the Vical board of directors’ consent, that the only material asset of Vical is the Vical Net Cash (as defined in the section titled “The Merger Agreement—Conditions to the Completion of the Merger”), that no other assets of Vical, including, without limitation, any net operating losses of Vical, have any material value and that Vical does not, and does not intend to, engage in any activity that may result in the generation of any revenue. MTS Securities was also instructed by Vical, and assumed, at Vical’s direction and with the Vical board of directors’ consent, that (i) (a) Vical Net Cash at the closing of the Merger is expected to be $34.7 million but in no case less than $30 million, (b) if Vical Net Cash is between $34.2 million and $35.2 million at the closing of the Merger, then no adjustment will be made, and (c) outside of such range, Vical’s valuation will be adjusted on adollar-for-dollar basis; and (ii) (a) the Company Net Working Capital (as defined in the section titled “The Merger Agreement—Conditions to the Completion of the Merger”) is expected to be between–$9.2 million and–$10.2 million, and (b) outside of such range, Brickell’s valuation will be adjusted on adollar-for-dollar basis.

MTS Securities assumed that the representations and warranties of each party contained in the Merger Agreement and in all other related documents and instruments that are referred to therein are and will be true and correct as of the date or the dates made or deemed made, that each party thereto will fully and timely perform all of the covenants and agreements required to be performed by it under the Merger Agreement and any other agreement contemplated thereby and that the transactions contemplated by the Merger Agreement, including, without limitation, the Merger, will be consummated in accordance with the terms of the Merger Agreement without waiver, modification or amendment of any term, condition or agreement. MTS Securities assumed that the final form of the Merger Agreement will be in all material respects identical to the Draft Merger Agreement. MTS Securities, with the Vical board of directors’ consent, further assumed that any adjustment to the Exchange Ratio pursuant to the terms of the Merger Agreement will not result in any adjustment to the Exchange Ratio that is material to MTS Securities’ analysis. MTS Securities also assumed that any governmental, regulatory and other consents and approvals contemplated in connection with the Merger will be obtained and that, in the course of obtaining any of those consents and approvals, no restrictions will be imposed or waivers made that would have an adverse effect on Vical, Brickell or the contemplated benefits of the Merger.

The MTS Opinion is necessarily based on economic, market, financial and other conditions as they exist, and on the information made available to MTS Securities as of the date of such opinion. MTS Securities did not consider any potential legislative or regulatory changes currently being considered by the United States Congress, the SEC, or any other governmental or regulatory bodies, or any changes in accounting methods or generally accepted accounting principles that may be adopted by the SEC or the Financial Accounting Standards Board. It should be understood that, although subsequent developments may affect the conclusion reached in the MTS Opinion, MTS Securities does not have any obligation to update, revise or reaffirm the MTS Opinion.

82.

The MTS Opinion addresses solely the fairness, from a financial point of view and as of the date of such opinion, of the Exchange Ratio to the holders of Vical common stock and does not address any other terms in the Merger Agreement, or any other agreement contemplated by the Merger Agreement or relating to the Merger or any other aspect or implication of the Merger, including, without limitation, the form or structure of the Merger or the fairness of the Merger or the Exchange Ratio to any other securityholders or creditors or any other constituency of Vical. The MTS Opinion does not address Vical’s underlying business decision to proceed with the Merger or the relative merits of the Merger compared to other alternatives available to Vical. MTS Securities expressed no opinion as to the prices or ranges of prices at which shares of securities of any person, including Vical or Brickell, will trade at any time, including following the announcement or consummation of the Merger. MTS Securities was not requested to opine as to, and the MTS Opinion did not in any manner address, the amount or nature of compensation to any of the officers, directors or employees of any party to the Merger, or any class of such persons, relative to the compensation to be paid to the holders of Vical common stock in connection with the Merger or with respect to the fairness of any such compensation.

In accordance with customary investment banking practice, MTS Securities employed generally accepted valuation methods in reaching its opinion. The MTS Opinion was reviewed and approved by a fairness committee of MTS Securities.

Summary of Financial Analysis

MTS Securities performed a variety of financial analyses for purposes of rendering its opinion. The preparation of a fairness opinion is a complex process and is not susceptible to partial analysis or summary description. In arriving at its opinion, MTS Securities considered the results of all of its analyses as a whole and did not attribute any particular weight to any analysis or factor considered. Each analytical technique has inherent strengths and weaknesses, and the nature of the available information may further affect the value of particular techniques. The overall conclusions MTS Securities reached were based on all the analyses and factors presented, taken as a whole, and also on application of MTS Securities’ own experience and judgment. Such conclusions may involve significant elements of subjective judgment and qualitative analysis. MTS Securities therefore gave no opinion as to the value or merit standing alone of any one or more parts of the analyses. Furthermore, MTS Securities believes that the summary provided and the analyses described below must be considered as a whole and that selecting any portion of the analyses, without considering all of them, would create an incomplete view of the process underlying MTS Securities’ analysis and opinion. As a result, the ranges of valuations resulting from any particular analysis or combination of analyses described below should not be taken to be the view of MTS Securities with respect to the actual value of Vical, Vical common stock, Brickell or Brickell common stock.

Some of the summaries of the financial analyses include information presented in tabular format. The tables must be read together with the full text of the corresponding summaries and are alone not a complete description of the financial analyses performed by MTS Securities. Considering the data in the tables below without considering the corresponding full narrative descriptions of the financial analyses, including the methodologies and assumptions underlying such analyses, could create a misleading or incomplete view of the financial analyses performed by MTS Securities.

In performing its analyses, MTS Securities made numerous assumptions with respect to industry performance, general business, regulatory and economic conditions and other matters, all of which are beyond MTS Securities’ control and many of which are beyond the control of Vical and/or Brickell. Any estimates used by MTS Securities in its analysis are not necessarily indicative of future results or actual values, which may be significantly more or less favorable than those suggested by such estimates.

MTS Securities performed stand-alone valuation analyses of both Vical and Brickell using a variety of valuation methodologies, as described below. MTS Securities then performed a relative valuation analysis in order to compare the Exchange Ratio to the range of exchange ratios implied based on the respective stand-alone

83.

valuation ranges. Except as otherwise noted, the following quantitative information, to the extent that it is based on market data, is based on market data as it existed on or before May 31, 2019 and is not necessarily indicative of current market conditions.

Vical Valuation Analysis

Liquidation Analysis

As noted above, at the direction of Vical’s management and with the Vical board of directors’ consent, MTS Securities assumed that the only material asset of Vical was its cash and that Vical does not currently, and does not intend in the future to, conduct any activity that may result in the generation of revenue. Accordingly, MTS Securities considered an appropriate measure of the implied equity value of Vical common stock to be the amount of cash available for distribution to Vical stockholders in an orderly liquidation of Vical. Based on information provided by Vical’s management (net cash of $43.0 million as of April 30, 2019; estimated employee-related wind-down costs of $3.6 million; estimatednon-employee related wind-down costs of $1.0 million; estimated liquidation costs of $1.8 million; fully diluted shares outstanding using the treasury stock method of 29.0 million, which includes 6.2 million of prefunded warrants with an exercise price of $0.01; and an estimated liquidation date of July 31, 2019) MTS Securities calculated the per share equity value of Vical to be $1.26, as of July 31, 2019. The analysis assumed cash distributions net of known liabilities and, to be conservative, without retaining any funds in reserve for unknown or contingent liabilities.

MTS Securities compared this per share equity liquidation value to the implied merger valuation of $1.36 per share.

Historical Stock Price Performance

MTS Securities reviewed the share price trading history of Vical common stock for the period beginning on June 11, 2018, the day Vical announced that its Phase 2 HSV2 clinical trial failed to meet its primary endpoint, and ending on May 31, 2019. During this period, shares of Vical common stock traded as low as $0.85 per share and as high as $1.47 per share, compared to the closing price of Vical common stock on May 31, 2019 of $1.15 per share. In addition, MTS Securities reviewed the volume weighted average trading price over the five trading day, 10 trading day, 30 trading day, 60 trading day, six month and 12 month periods ending on May 31, 2019. These volume weighted average prices (“VWAP”) are set forth in the table below:


Trading Period	VWAP
5 Trading Day	$	1.14
10 Trading Day	$	1.14
30 Trading Day	$	1.14
60 Trading Day	$	1.16
6 Months	$	1.04
12 Months	$	1.13

MTS Securities noted that the share price trading history and volume weighted average trading prices were provided to the Vical board of directors for informational purposes only and were not relied upon by MTS Securities for valuation purposes.

Brickell Valuation Analysis

MTS Securities analyzed the valuation of Brickell using three different methodologies: a discounted cash flow analysis, a public trading comparable companies analysis and an analysis of initial public offerings of companies MTS Securities deemed relevant. The results of each of these analyses are summarized below.

84.

Discounted Cash Flow Analysis

MTS Securities reviewed and analyzed the unlevered free cash flows (defined as probability of success adjusted operating income less income tax expense, less capital expenditures, plus depreciation and amortization, less changes in working capital; for detailed projections, please see the section titled “Certain Vical ManagementUnaudited Prospective Financial Information”) that Vical’s management expects Brickell will generate during the period beginning on August 15, 2019 and ending on December 31, 2034. To be conservative, the analysis did not include Brickell’s estimated NOL balance at transaction closing and did not include a terminal value, either of which would have resulted in a higher value for Brickell than that implied by the analysis. The unlevered free cash flows (excluding NOLs) were then discounted to present values using a range of discount rates, reflecting calculated estimates of Brickell’s weighted average cost of capital (“WACC”), based upon MTS Securities’ analysis of the cost of capital for both of Brickell’s comparable company universes, as described in more detail under “The Merger—Opinion of MTS Securities, LLC—Brickell Valuation Analysis—Public Trading Comparable Companies Analysis” below.

At the direction of Vical, MTS Securities conducted certain sensitivity analyses for purposes of its discounted cash flow analysis using ranges of: (i) revenue achievement factors of 75% to 125%, as provided by Vical’s management; (ii) U.S. probabilities of success of 60% to 80%, as provided by Vical’s management and based upon estimates of the likelihood of approval; and (iii) weighted average cost of capital of 12% to 14%.

For each sensitivity described above, an implied range of total and per share equity values was calculated based on Brickell’s projected capitalization at transaction closing. The below table reflects the range of values implied by this analysis, which were compared to Brickell’s implied total and per share equity value of $60.0 million and $4.40, respectively, in the Merger.


Metric	Metric Range	Implied Equity Value of Brickell (millions)	Implied Value of Each Brickell Share
Revenue Achievement and WACC	75% – 125%	$70 – $460	$5.00 – $47.75
U.S. Cumulative Probability of Success and WACC	60% – 80%	$185 – $330	$17.75 – $33.25

MTS Securities noted that the total and per share equity value of Brickell common stock implied by this analysis was greater than the corresponding equity and per share values implied by the Exchange Ratio.

Public Trading Comparable Companies Analysis

MTS Securities reviewed and compared the projected operating performance of Brickell with publicly available information concerning other publicly traded companies and reviewed the current market price of certain publicly traded securities of such other companies. MTS Securities utilized two sets of comparable companies: (i) selected mid to late stage 505(b)(2) and new chemical entity (“NCE”) dermatology companies; and (ii) specialty NCE development stage companies with Phase 2 data. The companies included in each set are as follows:

Selected Mid to Late Stage 505(b)(2) and NCE Dermatology Companies:

•

Dermira, Inc.

•

Krystal Biotech, Inc.

•

Cassiopea S.p.A.

•

Biofrontera AG

•

Aclaris Therapeutics, Inc.

•

Trevi Therapeutics, Inc.

85.

•

Verrica Pharmaceuticals Inc.

•

Menlo Therapeutics Inc.

•

Foamix Pharmaceuticals Ltd.

•

Novan, Inc.

•

Sienna Biopharmaceuticals, Inc.

Selected Specialty NCE Development Stage Companies with Phase 2 data:

•

Aurinia Pharmaceuticals Inc.

•

Resverlogix Corp.

•

Milestone Pharmaceuticals Inc.

•

resTORbio, Inc.

•

Minerva Neurosciences, Inc.

•

Trevi Therapeutics

•

Menlo Therapeutics Inc.

•

Quantum Genomics Société Anonyme

•

Innovate Biopharmaceuticals, Inc.

•

Sienna Biopharmaceuticals, Inc.

Although none of the selected companies is directly comparable to Brickell, MTS Securities included these companies in its analysis because they are publicly traded companies with certain characteristics that, for purposes of analysis, may be considered similar to certain characteristics of Brickell.

MTS Securities calculated the enterprise value (“EV”) for the Selected Mid to Late Stage 505(b)(2) and NCE Dermatology Companies, as of May 31, 2019, and the EV and the ratio of EV to Peak Sales for the Selected Specialty NCE Development Stage Companies with Phase 2 Data, using consensus equity research estimates as of May 31, 2019 for such companies.

The following are the summary statistics associated with such companies.


	Selected Mid to Late Stage 505(b)(2) and NCE Dermatology Companies (millions)		Selected Specialty NCE Development Stage Companies with Phase 2 Data (millions)
	Enterprise Value		Enterprise Value		Enterprise Value/ Peak Sales
Top Quartile	$	358	$	316		0.29x
Mean	$	187	$	208		0.24x
Median	$	100	$	110		0.16x
Low Quartile	$	54	$	58		0.11x

For purposes of this analysis, the enterprise value of each comparable company was calculated by multiplying the closing price per share of common stock of such company on May 31, 2019 by the number of such company’s fully diluted outstanding shares, using the treasury stock method, and adding to that result such company’s net debt, preferred stock and minority interest.

MTS Securities derived a low quartile and top quartile EV range, as well as a low quartile and top quartile multiple range for EV/Peak Sales for the comparable companies. MTS Securities applied the low quartile and top

86.

quartile ranges to the corresponding valuation metrics of Brickell to derive a range of equity valuations based upon each metric, EV and EV/Peak Sales, after adjusting for net debt, preferred stock and minority interest as appropriate. The EV/Peak Sales multiple range was applied to the 2028 estimate of sofpironium bromide U.S. unadjusted sales.

The table below notes the implied total and per share equity value ranges of Brickell (rounded to the nearest $0.25, for each metric), which were compared to Brickell’s implied total and per share equity value of $60.0 million and $4.40, respectively, in the Merger.

MTS Securities noted that the total and per share equity value of Brickell common stock implied by the Exchange Ratio was at the low end of the range of values implied by this analysis.

IPO Comparables Analysis

MTS Securities also analyzed thepre- and post-money equity valuations andpre-money enterprise values of the following specialty NCE development stage companies with Phase 2 data, each of which had completed an initial public offering in 2017 or later:

•

Milestone Pharmaceuticals Inc. (5/8/2019)

•

Trevi Therapeutics, Inc. (5/7/2019)

•

Urovant Sciences Ltd. (9/26/2018)

•

Adial Pharmaceuticals, Inc. (7/26/2018)

•

Verrica Pharmaceuticals Inc. (6/14/2018)

•

Menlo Therapeutics Inc. (1/24/2018)

•

Biohaven Pharmaceutical Holding Company Ltd. (5/3/2017)

•

ObsEva SA (1/25/2017)

MTS derived the following summary statistics for the pre-money enterprise values of these companies.


Top Quartile (millions)	Mean (millions)	Median (millions)	Low Quartile (millions)
$301	$209	$217	$186

MTS Securities then applied these low quartile and top quartile ranges ofpre-money enterprise value to imply a corresponding range of enterprise values of Brickell to derive low and top equity valuations for Brickell based upon each metric, after adjusting for net debt, preferred stock and minority interest as appropriate.

The table below notes the implied total and per share equity values of Brickell (rounded to the nearest $5 million and $0.25, respectively, for each metric), which were compared to Brickell’s implied total and per share equity value of $60.0 million and $4.40, respectively, in the merger.

MTS Securities noted that the total and per share equity value of Brickell common stock implied by this analysis was greater than the corresponding equity and per share value implied by the Exchange Ratio.

Relative Valuation Analysis

MTS Securities compared the liquidation value per share of Vical common stock to the low and high values per share of Brickell common stock implied by the Brickell Valuation Analysis above to determine the implied range of exchange ratios, in terms of the number of shares of Vical common stock to be received by Brickell shareholders for each share of Brickell common stock held by them.

MTS Securities also analyzed the range of implied total and per share equity values to holders of Vical common stock in the pro forma combined company, assuming 40% Vical ownership in the pro forma combined company, as specified by the Exchange Ratio. The pro forma combined company valuation was calculated by adding the estimated net cash contributed by Vical in the merger, $34.7 million, to the equity valuation ranges in the Brickell Valuation Analysis above. MTS Securities compared these values to the total and per share liquidation value of Vical.

The following table sets forth the results of these analyses:

MTS Securities compared these ranges of implied exchange ratios to the Exchange Ratio in the Merger and found that, in all but one instance, the range of exchange ratios implied by these analyses was higher than the Exchange Ratio in the Merger, and in one instance, the Exchange Ratio in the Merger was at the low end of the range of exchange ratios implied by this analysis.

MTS Securities also compared these ranges of implied per share equity values to holders of Vical common stock in the pro forma combined company to the liquidation value of Vical and found that, in each instance, the per share liquidation value of Vical was below the range of implied per share values to holders of Vical common stock in the pro forma combined company.

Miscellaneous

The preparation of a fairness opinion is a complex analytical process involving various determinations as to the most appropriate and relevant methods of financial analysis and the application of those methods to the particular circumstances and, therefore, a fairness opinion is not readily susceptible to summary description. In arriving at its opinion, MTS Securities did not draw, in isolation, conclusions from or with regard to any factor or analysis that it considered. Rather, MTS Securities made its determination as to fairness on the basis of its experience and professional judgment after considering the results of all of the analyses.

88.

The MTS Opinion was one of the many factors taken into consideration by the Vical board of directors in making its determination to approve the Merger Agreement. Consequently, the analyses as described above should not be viewed as determinative of the opinion of the Vical board of directors with respect to the Merger or of whether the Vical board of directors would have been willing to agree to different terms. The Exchange Ratio was determined througharm’s-length negotiations between Vical and Brickell and was approved by the Vical board of directors. MTS Securities and its affiliates provided advice to Vical during these negotiations. However, neither MTS Securities nor any of its affiliates recommended any specific amount of consideration to Vical or the Vical board of directors or that any specific amount of consideration constituted the only appropriate consideration for the Merger.

MTS Securities and its affiliates, as part of their investment banking services, are regularly engaged in the valuation of businesses (including those in the healthcare industry) and securities in connection with mergers and acquisitions, and for other purposes. As noted above, MTS acted as a financial advisor to Vical in connection with the Merger and participated in certain of the negotiations leading to the Merger Agreement. Vical selected MTS as its financial advisor because it is nationally recognized in the healthcare industry as having investment banking professionals with significant experience in healthcare investment banking and merger and acquisition transactions, including transactions similar to the Merger. Pursuant to an engagement letter agreement, dated as of July 16, 2018, between Vical and MTS, Vical engaged MTS to act as its financial advisor in connection with Vical’s consideration, evaluation and/or exploration of certain potential merger and acquisition transactions or similar transactions. As permitted by the terms of the engagement letter and pursuant to MTS’s internal policies, MTS Securities rather than MTS, delivered the MTS Opinion. As compensation for MTS Securities’ and its affiliates’ financial advisory services, Vical paid anon-refundable retainer fee of $100,000 and paid a fee of $300,000 to MTS Securities for rendering the MTS Opinion in connection with the Vical board of directors’ consideration of the proposed transaction with Brickell, which fee was not contingent upon the successful completion of the Merger or the conclusion reached within the MTS Opinion. Upon consummation of the Merger, Vical will be obligated to pay to MTS a transaction fee equal to approximately $2,000,000, of which up to $500,000 of such fee may be payable in shares of the combined company’s common stock based upon the closing price of Vical common stock on the day of the consummation of the Merger. All fees previously paid pursuant to the engagement letter by Vical credited towards the cash portion of the transaction fee, including the fee paid by Vical upon delivery of the MTS Opinion. In addition, Vical also agreed to reimburse to MTS and its affiliates for their direct, reasonable and documentedout-of-pocket expenses incurred in connection with any of the matters contemplated in the engagement letter. Vical also agreed to indemnify to MTS and each of its related parties against various liabilities in connection with their engagement.

During the two years preceding the date of the MTS Opinion, neither MTS Securities nor MTS has been engaged by, performed services for, or received any compensation from, Vical or Brickell (other than the engagements and any amounts that were paid under the engagement letter with Vical described above). MTS Securities, MTS and their affiliates may seek to provide investment banking and/or financial advisory services to Vical and Brickell in the future and would expect to receive customary fees for the rendering of any such services.

Interests of the Vical Directors and Executive Officers in the Merger

In considering the recommendation of the Vical board of directors to approve the Closing Stockholder Matters (as defined in the section titled “The Merger Agreement—The Special Meeting”), the Vical stockholders should be aware that some of our directors and executive officers have interests in the Merger that are different from, or in addition to, the interests of our stockholders generally. These interests may present them with actual or potential conflicts of interest, and these interests, to the extent material, are described below.

Our board of directors was aware of these potential conflicts of interest and considered them, among other matters, in reaching its conclusion (i) that the Merger and all related transactions set forth in and contemplated by the Merger Agreement are fair to, advisable and in the best interests of Vical and its stockholders and (ii) to

89.

approve and declare advisable the Merger Agreement and the Contemplated Transactions, and to recommend, upon the terms and subject to the conditions set forth in Merger Agreement, that the stockholders of Vical vote to approve the Closing Stockholder Matters (as defined in the section titled “The Merger Agreement—The Special Meeting”).

Ownership Interests

As of June 26, 2019, all directors and executive officers of Vical beneficially owned approximately 5.6% of the shares of Vical common stock.

Director Positions Following the Merger

Vijay B. Samant, currently the President and Chief Executive Officer of Vical and a member of its board of directors, is expected to resign from his position as President and Chief Executive Officer of Vical as of the effective time of the Merger. Mr. Samant will continue as a director of the combined company after the effective time of the Merger.

Gary A. Lyons is currently a director of Vical and will continue as a director of the combined company after the effective time of the Merger.

Potential Merger-Related Compensation of Named Executive Officers

The following table and the related footnotes present information about the compensation payable to Vical’s current named executive officers that is based on or otherwise relates to the Merger. The compensation shown in the table below is intended to comply with Item 402(t) of RegulationS-K, which requires disclosure of information about compensation for each Vical named executive officer that is based on or otherwise relates to the Merger.

Larry R. Smith, Ph.D., Vical’s former Senior Vice President, Research, ceased employment with Vical effective May 21, 2019 and was subsequently engaged as a consultant to Vical. Vical entered into a separation agreement with Dr. Smith pursuant to which Dr. Smith received alump-sum cash payment equal to 12 months of his base salary as in effect on his separation date, plus the annual bonus he received in the12-month period preceding his termination. Dr. Smith is also entitled to receive COBRA benefits for a period of 12 months post-termination and received acceleration of his equity awards that would have otherwise vested during the12-month period after his termination. Dr. Smith’s separation agreement further provides that, in the event of a “change in control,” as defined in the severance agreement, during Dr. Smith’s service as a consultant, Dr. Smith will be entitled to a lump sum payment equal to six months of base salary in effect on the date of his employment separation. For purposes of Dr. Smith’s separation agreement, the Merger, if consummated, will constitute a change of control transaction. In addition, all outstanding unvested equity awards held by Dr. Smith will vest immediately.

Mammen P. Mammen, Jr., M.D. was terminated on February 19, 2019 in connection with Vical’s decision to discontinue the clinical development ofVL-2397. In accordance with his separation agreement, Dr. Mammen received severance benefits as described in Vical’s Annual Report on Form10-K for the year ended December 31, 2018, as amended, and is entitled to no additional compensation in connection with the Merger.

Vijay B. Samant, Vical’s President and Chief Executive Offer and a member of its board of directors, is expected to be terminated as an officer of Vical effective as of the closing of the Merger but will continue as a director of the combined company after the effective time of the Merger. Vical entered into an employment agreement with Mr. Samant providing that, in the event of Mr. Samant’s termination of employment on or within 24 months of a “change in control,” as defined in the employment agreement, Mr. Samant will be entitled to a lump sum payment equal to 24 months of base salary, at his then-current rate, plus a payment equal to one and

90.

one-half times his cash bonus paid during the previous 12 months, and the payment of health insurance premiums for 18 months. For purposes of Mr. Samant’s employment agreement, the Merger, if consummated, will constitute a change of control transaction. In addition, all outstanding unvested equity awards held by Mr. Samant will vest immediately.

All of Vical’s outstanding equity-based awards include provisions that accelerate vesting of such awards in the event of a change of control. A change of control is defined as the occurrence of either of the following events: (i) a change in the composition of Vical’s board of directors, as a result of which fewer than 50% of the incumbent directors are directors who either: (a) had been directors of Vical 24 months prior to such change; or (b) were elected, or nominated for election, to Vical’s board of directors 24 months prior to such change and who were still in office at the time of the election or nomination; or (ii) any person becomes, by acquisition or aggregation of securities, the beneficial owner of securities of Vical representing 50% or more of the combined voting power of Vical’s securities eligible to vote for the election of directors. For purposes of the equity-based awards, the Merger, if consummated, will constitute a change of control.

The cash and perquisites/benefits disclosure provided by the table below is quantified assuming that the Merger closed. The equity disclosure provided in this table is quantified assuming that the Merger closed. The named executive officers are not entitled to any pension ornon-qualified deferred compensation benefits enhancements, or any other form of compensation that is based on or otherwise related to the Merger.

Please note that the amounts indicated below are estimates based on multiple assumptions that may or may not actually occur (including assumptions described in this proxy statement) or may occur at times different than the time assumed. Some of these assumptions are based on information currently available and, as a result, the actual amounts, if any, to be received by the named executive officers may differ in material respects from the amounts set forth below. The amounts in the chart are “double trigger” in nature, in that they require both the occurrence of the Merger and a qualifying termination of employment.

(1)

The amount of Mr. Samant’s cash payment represents an aggregate amount equal to (i) 24 months of Mr. Samant’s base salary in effect as of January 1, 2019 (i.e., $1,182,440) and (ii) one andone-half times Mr. Samant’s cash bonus paid during the previous 12 months (i.e., $390,000). Mr. Samant must enter into a release agreement to be eligible to receive the above described cash payment. The cash payment is payable in a lump sum within 60 days of the effective date of the release agreement.

The amount of Dr. Smith’s cash payment represents a payment equal to six months of his base salary as in effect on his separation date (i.e., $156,050). Dr. Smith must enter into a supplemental release agreement to be eligible to receive the above described cash payment. The cash payment is payable in a lump sum within 60 days of the effective date of the supplemental release agreement.

On February 19, 2019, Dr. Mammen was terminated and received a severance payment in accordance with his separation agreement. Dr. Mammen previously entered into a release agreement in connection with his termination, and is entitled to no additional compensation in connection with the Merger.

(2)	Each of Mr. Samant and Dr. Smith is entitled to full acceleration of any unvested equity awards upon the consummation of the Merger. Dr. Mammen is not entitled to any acceleration of equity awards in

91.

connection with the Merger. Calculating the price per share based on the average closing market price of Vical’s common stock over the first five business days following the public announcement of the proposed Merger (i.e., June 3, 2019), all outstanding Vical options areout-of-the-money, and thus the aggregate dollar value of the accelerated equity awards is $0.

(3)

The amount of Mr. Samant’s perquisite/benefits represents an aggregate amount equal to the COBRA premium Mr. Samant is currently expected to receive (i.e., $45,273). Mr. Samant must enter into a release agreement to be eligible to receive the above described benefit. The COBRA premium benefit is payable until the earliest of 18 months following Mr. Samant’s termination of employment, the expiration of his eligibility under COBRA or the date he becomes eligible for health insurance benefits under a subsequent employer.

Vical Director Compensation Arrangements

The intrinsic value of the unvested stock options held by thenon-employee directors that will accelerate and vest in connection with the Merger is $0. “Intrinsic value” with respect to such stock options refers to the average closing market price of Vical’s common stock over the first five business days following the public announcement of the proposed Merger (i.e., June 3, 2019), over the exercise price of the Vical options held by thenon-employee directors that were unvested as of June 26, 2019. Calculating the price per share based on the average closing market price of Vical’s common stock over the first five business days following the public announcement of the proposed Merger (i.e., June 3, 2019), all outstanding Vical options areout-of-the-money.

Indemnification of the Vical Officers and Directors

The Merger Agreement provides that, for a period of six years following the effective time of the Merger, Vical will fulfill and honor in all respects the obligations of Vical that existed prior to the date of the Merger Agreement to indemnify Vical’s present and former directors and officers and their heirs, executors and assigns. Vical has entered into indemnification agreements with each of Vical’s current directors and executive officers that require Vical to indemnify these individuals to the fullest extent permitted under Delaware law against liabilities that may arise by reason of their service to Vical and to advance expenses incurred as a result of any proceeding against them as to which they could be indemnified.

The Merger Agreement provides that, for a period of six years following the effective time of the Merger, the provisions relating to the indemnification and elimination of liability for monetary damages set forth in the certificates of incorporation and bylaws of Vical will not be amended, repealed or otherwise modified in any manner that would adversely affect the rights thereunder of individuals who, at the effective time, were directors, officers, employees or agents of Vical, unless such modification is required by law.

The Merger Agreement also provides that, for a period of six years following the effective time of the Merger, Vical will maintain either a directors’ and officers’ liability insurance policy or a “tail” policy covering existing directors and officers of Vical. In addition, the Merger Agreement provides that Vical shall secure a “tail” policy on Vical’s existing directors’ and officers’ liability insurance policy for a period of six years following the effective time of the Merger for Vical’s existing directors and officers.

Structure

Under the Merger Agreement, Merger Sub, a wholly owned subsidiary of Vical formed in connection with the Merger, will merge with and into Brickell, with Brickell surviving as a wholly owned subsidiary of Vical.

After completion of the Merger, Vical will be renamed “Brickell Biotech, Inc.” and expects to trade on the Nasdaq Capital Market under the symbol “BBI.”

92.

Merger Consideration and Exchange Ratio

For a discussion of merger consideration and the Exchange Ratio, please see the section titled “The Merger Agreement—Merger Consideration and Exchange Ratio” beginning on page 95.

Effective Time of the Merger

The Merger Agreement requires the parties to consummate the Merger after all of the conditions to the consummation of the Merger contained in the Merger Agreement are satisfied or waived. The Merger will become effective upon the filing of a certificate of Merger with the Secretary of State of the State of Delaware or at such later time as is agreed by Vical and Brickell and specified in the certificate of Merger. Neither Vical nor Brickell can predict the exact timing of the consummation of the Merger.

Regulatory Approvals

Vical must comply with applicable federal and state securities laws and the rules and regulations of Nasdaq in connection with the issuance of shares of Vical common stock and the filing of this proxy statement with the SEC. Vical does not intend to seek any regulatory approval from antitrust authorities to consummate the transactions.

Certain Material U.S. Federal Income Tax Consequences of the Merger

Regardless of whether the Merger will qualify for U.S. federal income tax purposes as a reorganization within the meaning of Section 368(a) of the Code, the Merger will not result in any taxable gain or loss for U.S. federal income tax purposes to Brickell, Vical or any Vical stockholder in his, her or its capacity as a Vical stockholder. Vical stockholders who are also stockholders of Brickell, if any, should consult their own tax advisors as to the tax consequences to them of participating in the Merger with respect to their Brickell stock.

The foregoing discussion is for general information purposes only and is not intended to be a complete analysis or description of all potential U.S. federal income tax consequences of the Merger. In addition, the discussion does not address tax consequences which may vary with, or are contingent on, your individual circumstances. Moreover, the discussion does not address anynon-income tax or any foreign, state or local tax consequences of the Merger. Accordingly, you are strongly encouraged to consult with your own tax advisor as to the tax consequences of the Merger in your particular circumstances, including the applicability and effect of the alternative minimum tax and any state, local or foreign and other tax laws and of changes in those laws.

Nasdaq Capital Market Listing

Vical common stock currently is listed on Nasdaq under the symbol “VICL.” Vical has agreed to use commercially reasonable efforts to (i) prepare and submit to Nasdaq a notification form for the listing of the shares of Vical common stock to be issued to Brickell stockholders pursuant to the Contemplated Transactions, (iii) effect the Reverse Split subject to stockholder approval and (iii) the extent required by Nasdaq Marketplace Rule 5110, file the Nasdaq Listing Application and to cause such listing application to be approved for listing.

In addition, under the Merger Agreement, each of Brickell’s and Vical’s obligation to complete the Merger is subject to the satisfaction or waiver by each of the parties, at or prior to the Merger, of various conditions, including that the shares of Vical common stock to be issued in the Merger have been approved for listing on Nasdaq as of the closing of the Merger.

If the Nasdaq Listing Application is accepted, Vical anticipates that the common stock of the combined company will be listed on Nasdaq following the closing of the Merger under the trading symbol “BBI.”

THE MERGER AGREEMENT

The following is a summary of the material terms of the Merger Agreement. A copy of the Merger Agreement is attached as Appendix A to this proxy statement and is incorporated by reference. The Merger Agreement has been attached to this proxy statement to provide you with information regarding its terms. It is not intended to provide any other factual information about Vical, Brickell or Merger Sub. The following description does not purport to be complete and is qualified in its entirety by reference to the Merger Agreement. You should refer to the full text of the Merger Agreement for details of the Merger and the terms and conditions of the Merger Agreement.

The Merger Agreement contains representations and warranties that Vical and Merger Sub, on the one hand, and Brickell, on the other hand, have made to one another as of specific dates. These representations and warranties have been made for the benefit of the other parties to the Merger Agreement and may be intended not as statements of fact but rather as a way of allocating the risk to one of the parties if such statements made in the representations and warranties prove to be incorrect. In addition, the assertions made in the representations and warranties are qualified by the information in confidential disclosure schedules exchanged by the parties in connection with the signing of the Merger Agreement. While Vical and Brickell do not believe that these disclosure schedules contain information required to be publicly disclosed under the applicable securities laws, other than information that has already been so disclosed, the disclosure schedules do contain information that modifies, qualifies and creates exceptions to the representations and warranties set forth in the Merger Agreement. Accordingly, you should not rely on the representations and warranties as current characterizations of factual information about Vical, Brickell or Merger Sub, because they were made as of specific dates, may be intended merely as a risk allocation mechanism between Vical and Merger Sub on the one hand, and Brickell on the other hand, and are modified by the disclosure schedules.

Structure

Completion and Effectiveness of the Merger

The Merger will be completed as promptly as practicable after all of the conditions to completion of the Merger are satisfied or waived, including the approval of the stockholders of Vical, but no later than November 15, 2019. The required Brickell stockholder approval was obtained prior to the execution of the Merger Agreement. The Merger is anticipated to occur after the Special Meeting, which is further described on page 61. However, Vical and Brickell cannot predict the exact timing of the completion of the Merger because it is subject to various conditions.

Merger Consideration and Exchange Ratio

Merger Consideration

No fractional shares of Vical common stock will be issued in connection with the Merger. Instead, each Brickell stockholder who otherwise would be entitled to receive a fractional share of Vical common stock (after aggregating all fractional shares of Vical common stock issuable to such holder) will be entitled to receive an

95.

amount in cash, rounded to the nearest whole cent and without interest, determined by multiplying such fraction by the volume weighted average closing trading price of a share of Vical common stock on the Nasdaq Capital Market for the five consecutive trading days ending five trading days immediately prior to the date upon which the Merger becomes effective.

Prior to the effective time of the Merger, Brickell will convert accrued dividends on Brickell’s preferred stock through May 31, 2019 at the Merger price per share of Brickell common stock.

Exchange Ratio

The Exchange Ratio is calculated using a formula intended to allocate to the former Brickell securityholders and NovaQuest, collectively, approximately 60% of the aggregate number of shares of Vical common stock, and to the securityholders of Vical as of immediately prior to the Merger approximately 40% of the aggregate number of shares of Vical common stock (in each case on a fully diluted basis using the treasury stock method in instances other than with respect to the NovaQuest Warrants and certain equity issuances by Brickell following the signing of the Merger Agreement and prior to the completion of the Merger).

The exchange ratio formula is the quotient obtained by dividing the number of Brickell Merger Shares (as defined below) by the Brickell Outstanding Shares (as defined below), where:

•

“Brickell Merger Shares” means the product determined by multiplying (i) the Post-Closing Vical Shares by (ii) the Brickell Allocation Fraction;

•

“Brickell Outstanding Shares” means the total number of shares of Brickell capital stock outstanding immediately prior to the effective time of the Merger expressed on a fully-diluted andas-converted to Brickell common stock basis, assuming, without limitation or duplication, (i) calculated in the case of this clause (i) based on the treasury stock method, the issuance of shares of Brickell capital stock in respect of all Brickell options, warrants, convertible notes and other outstanding options, warrants, convertible notes or rights to receive such shares, in each case, outstanding as of immediately prior to the effective time of the Merger (assuming cashless exercise using the implied share price based on proposed equity value in this transaction for purposes of the treasury stock method calculation) whether conditional or unconditional and including any outstanding options, warrants or rights triggered by or associated with the consummation of the Merger (but excluding any shares of Brickell capital stock reserved for issuance other than with respect to outstanding Brickell options, warrants and convertible notes (for the avoidance of doubt including any Brickell convertible notes issued following the date of the Merger Agreement pursuant to the Note and Warrant Purchase Agreement, dated March 18, 2019, among Brickell and the persons listed on Exhibit A thereto, as in effect on the date of the Merger Agreement (the “Note Purchase Agreement”) (up to an aggregate amount of $7.5 million)); and (ii) without applying the treasury stock method, (A) the issuance of shares of Vical common stock in respect of the NovaQuest Warrants and (B) unless otherwise consented to by Vical or pursuant to the Note Purchase Agreement (up to an aggregate amount of $7.5 million), the issuance of shares of Brickell capital stock or Vical common stock in respect of (1) 75% of any Brickell options and (2) any convertible debt, warrants or other equity securities of Brickell or Vical, in the case of (1) and (2), that Brickell issues or commits to issue after the date of the Merger Agreement and prior to the closing of the Merger;

•

“Post-Closing Vical Shares” means the quotient determined by dividing (i) the Vical Outstanding Shares by (ii) the Vical Allocation Fraction;

•

“Brickell Allocation Fraction” the quotient (rounded to two decimal places) determined by dividing (i) the Brickell Valuation by (ii) the Aggregate Valuation;

•

“Vical Outstanding Shares” means the total number of shares of Vical common stock outstanding immediately prior to the effective time of the Merger expressed on a fully-diluted basis and using the

96.

treasury stock method, but assuming, without limitation or duplication, (i) the issuance of shares of Vical common stock pursuant to that certain Letter Agreement dated July 16, 2018, by and between Vical and MTS and (ii) the issuance of shares of Vical common stock in respect of all outstanding Vical options, warrants and other outstanding options, restricted stock units, warrants or rights to receive such shares, in each case, outstanding as of immediately prior to the effective time of the Merger (assuming, for purposes of the treasury stock method calculation, cashless exercise using the volume weighted average closing trading price of a share of Vical common stock on the Nasdaq Capital Market for the five consecutive trading days ending five trading days immediately prior to the date upon which the Merger becomes effective), whether conditional or unconditional and including any outstanding options, warrants or rights triggered by or associated with the consummation of the Merger, (but excluding any shares of Vical common stock reserved for issuance other than with respect to outstanding Vical options and warrants as of immediately prior to the effective time of the Merger). Noout-of-the-money Vical options or warrants shall be included in the total number of shares of Vical common stock outstanding for purposes of determining the Vical Outstanding Shares;

•

“Vical Allocation Fraction” means the quotient (rounded to two decimal places) determined by dividing (i) the Vical Valuation by (ii) the Aggregate Valuation;

•

“Aggregate Valuation” means the sum of (a) the Brickell Valuation, plus (b) the Vical Valuation;

•

“Vical Valuation” means $40,000,000,provided, that the Vical Valuation will be reduced by one dollar for each dollar that the Vical Net Cash (as defined in the section titled “The Merger Agreement—Conditions to the Completion of the Merger”) balance is less than $34,200,000 or increased by one dollar for each dollar that the Vical Net Cash balance is more than $35,200,000, in each case on the date of the Special Meeting and rounded to the nearest dollar.

Calculation of Vical Net Cash and Brickell Net Working Capital

Within five business days prior to the date of the Vical’s Stockholder Meeting, (a) Vical must deliver to Brickell a schedule (the “Net Cash Schedule”) setting forth Vical’s good faith estimate of its expected Vical Net Cash (the “Net Cash Calculation”) as prepared by Vical’s chief financial officer, together with the relevant work papers andback-up materials and (b) Brickell must deliver to Vical a net working capital schedule (the “Net Working Capital Schedule”) setting forth Brickell’s good faith estimate of its expected Brickell Net Working Capital (the “Net Working Capital Calculation”) as prepared by Brickell’s chief financial officer, together with the relevant work papers andback-up materials. The calculations and assumptions used in the Net Cash Schedule and the Net Working Capital Schedule must be consistent with the presentation and methodologies used in preparing the Vical Net Cash and Brickell Net Working Capital calculation, as applicable. Within two business days after Vical delivers the Net Cash Schedule to Brickell and Brickell delivers the Net Working Capital Schedule to Vical (the “Response Date”), the receiving party may dispute any part of such schedule by delivering a written notice (the “Dispute Notice”) to that effect to the other party.

If the parties agree on the amount of any of the deviations from the Net Cash Schedule or Net Working Capital Schedule, as applicable, during the Dispute Resolution Period, the Vical Net Cash or Brickell Net Working Capital amount, as applicable, they agree upon shall be final. If the parties, notwithstanding such good faith effort, fail to resolve such dispute within the Dispute Resolution Period, then the parties will jointly engage an independent accountant of national standing to make a written determination of Vical Net Cash or Brickell Net Working Capital, as applicable, as promptly as practicable, and such independent accountant’s determination will be final, absent manifest error or fraud.

Non-Solicitation

Both Vical and Brickell are prohibited by the terms of the Merger Agreement from (i) soliciting, initiating or knowingly encouraging, inducing or facilitating the communication, making, submission or announcement of any acquisition proposal or acquisition inquiry or taking any action that could reasonably be expected to lead to an acquisition proposal or acquisition inquiry; (ii) furnishing anynon-public information to any person in connection with or in response to an acquisition proposal or acquisition inquiry; (iii) engaging in discussions or negotiations with any person with respect to any acquisition proposal or acquisition inquiry; (iv) approving, endorsing or recommending any acquisition proposal; (v) executing or entering into any letter of intent or any contract contemplating or otherwise relating to any acquisition transaction; or (vi) publicly proposing to do any of the foregoing.

Pursuant to the terms of the Merger Agreement, each of Vical and Brickell must immediately cease any existing discussions, negotiations and communications with any person relating to any acquisition proposal or acquisition inquiry that have not already been terminated as of the date of the Merger Agreement and request the destruction or return of any of such party’s nonpublic information.

Subject to certain restrictions and prior to obtaining the required Vical stockholder vote, Vical may, however, providenon-public information to, and enter into discussions or negotiations with, any person that has made (and not withdrawn) a bona fide acquisition proposal, which the board of directors of Vical determines in good faith, after consultation with Vical’s outside financial advisors and outside legal counsel, constitutes, or could be reasonably likely to result in, a superior offer if: (A) neither Vical nor its representatives have breached thenon-solicitation restrictions in the Merger Agreement in any material respect, (B) Vical’s board of directors concludes in good faith based on the advice of outside legal counsel, that the failure to take such action could be reasonably likely to be inconsistent with the fiduciary duties of its board of directors under applicable law; (C) Vical receives from such person an executed confidentiality agreement containing provisions, in the aggregate, at least as favorable to such party as those contained in the Confidentiality Agreement dated as of January 31, 2019, between Vical and Brickell; and (D) substantially contemporaneously with furnishing any such nonpublic information to such person, Vical furnishes such nonpublic information to Brickell.

If Vical or Brickell, or any of their respective representatives, receives an acquisition proposal or acquisition inquiry prior to the closing of the Merger, then such party will (within one business day) advise the other party

104.

orally and in writing of such acquisition proposal or acquisition inquiry (including the identity of the person making such acquisition proposal or acquisition inquiry, and the material terms of the acquisition proposal or acquisition inquiry).

An acquisition proposal means any offer or proposal, whether written or oral (other than an offer or proposal between the parties) contemplating or otherwise relating to any acquisition transaction with a party.

An acquisition inquiry means an inquiry, indication of interest or request for information (other than an inquiry, indication of interest or request for information made between the parties) that would be reasonably likely to lead to an acquisition proposal.

A “Superior Offer” means an unsolicited bona fide written acquisition proposal (with all references to 20% in the definition of acquisition transaction being treated as references to greater than 80% for these purposes) that: (a) was not obtained or made as a direct or indirect result of a breach of the Merger Agreement, and (b) is on terms and conditions that such party’s board of directors determines in good faith, based on such matters that it deems relevant (including the likelihood of the consummation of the transaction), as well as any written offer by the other party to the Merger Agreement to amend the terms of the Merger Agreement, and following consultation with its outside legal counsel and outside financial advisors, if any, are more favorable, from a financial point of view, to such party’s stockholders than the terms of the Contemplated Transactions.

Pursuant to the Merger Agreement, as promptly as reasonably practicable after the resolution of SEC staff comments, if any, and the filing of the definitive proxy statement on Schedule 14A, Vical will take all action necessary under applicable law to call, give notice of and hold a Special Meeting of the holders of Vical common stock to vote on: (i) the amendment of Vical’s restated certificate of incorporation to effect the Reverse Split; (ii) the change of control resulting from the Merger pursuant to the Nasdaq Rules (the matters contemplated by clauses (i) through (ii) are collectively referred to as the “Closing Stockholder Matters”. Vical will take reasonable measures to ensure that all proxies solicited in connection with the Special Meeting are solicited in compliance with all applicable law. If, on or before the date of the Special Meeting, Vical reasonably believes that it (i) will not receive proxies sufficient to obtain the required approvals or (ii) will not have sufficient shares of Vical common stock represented to constitute a quorum necessary to conduct the business of the Special Meeting, Vical may postpone or adjourn, or make one or more successive postponements or adjournments of, the Special Meeting by up to 60 calendar days.

Vical agreed that, subject to certain exceptions in the Merger Agreement: (i) the Vical board of directors will recommend that the Vical stockholders vote to approve the Closing Stockholder Matters; (ii) this proxy

105.

statement would include a statement to the effect that the Vical board of directors recommends that the Vical stockholders vote to approve the Closing Stockholder Matters, (the “ Vical Board of Directors Recommendation”); and (iii) the Vical Board of Directors Recommendation would not be withheld, amended, withdrawn or modified (and the Vical board of directors would not publicly propose to withhold, amend, withdraw or modify the Vical Board of Directors Recommendation) in a manner adverse to Brickell (the actions set forth in the foregoing clause (iii), collectively, a “Vical Board of Directors Recommendation Change”).

The terms of the Merger Agreement provide that, if at any time prior to the approval of the Closing Stockholder Matters, Vical receives a written acquisition proposal (which did not arise out of a material breach of the Merger Agreement) from any person that has not been withdrawn and after consultation with outside legal counsel, the Vical board of directors has determined, in good faith, that such acquisition proposal is a superior offer, (x) the Vical board of directors may make a Vical Board of Directors Recommendation Change or (y) Vical may terminate the Merger Agreement to enter into an alternative agreement with respect to such superior offer, if and only if: (A) the Vical board of directors determines in good faith, after consultation with outside legal counsel, that the failure to do so could be inconsistent with the fiduciary duties of the Vical board of directors to the stockholders of Vical under applicable law; (B) Vical has given Brickell prior written notice of its intention to make the Vical Board of Directors Recommendation Change or terminate the Merger Agreement at least three business days prior to making the Vical Board of Directors Recommendation Change or terminating the Merger Agreement (a “Determination Notice”) (which notice will not constitute a Vical Board of Directors Recommendation Change); and (C) (1) Vical has provided to Brickell a summary of the material terms and conditions of the acquisition proposal, (2) Vical has given Brickell three business days after the Determination Notice to propose revisions to the terms of the Merger Agreement or make another proposal so that such Determination Notice would no longer necessitate a Vical Board of Directors Recommendation Change and has made its representatives reasonably available to negotiate in good faith with Brickell (to the extent Brickell desires to negotiate) with respect to such proposed revisions or other proposal, if any, and (3) after considering the results of any such negotiations and giving effect to the proposals made by Brickell, if any, after consultation with outside legal counsel, the Vical board of directors has determined, in good faith, that such acquisition proposal is a superior offer and that the failure to make the Vical Board of Directors Recommendation Change or terminate the Merger Agreement could be inconsistent with the fiduciary duties of the Vical board of directors to the Vical stockholders under applicable law. The provisions of the Merger Agreement described in this paragraph also apply to any material change to the facts and circumstances relating to such acquisition proposal and a new Determination Notice would be required following any such material change, except that the references to three business days in this paragraph would be deemed to be two business days.

The terms of the Merger Agreement also provide that, other than in connection with an acquisition proposal, the Vical board of directors may make a Vical Board of Directors Recommendation Change in response to a material development or change in circumstances (other than an acquisition proposal) that affects the business, assets or operations of Vical that occurs or arises after the date of the Merger Agreement and was neither known to Vical or the Vical board of directors nor reasonably foreseeable as of the date of the Merger Agreement (a “Vical Change in Circumstance”), if and only if: (A) the Vical board of directors determines in good faith, after consultation with outside legal counsel, that the failure to do so could be inconsistent with the fiduciary duties of the Vical board of directors to Vical’s stockholders under applicable law; (B) Vical has given Brickell a Determination Notice at least three business days prior to making any such Vical Board of Directors Recommendation Change; and (C) (1) Vical has specified the Vical Change in Circumstance in reasonable detail, (2) Vical has given Brickell three business days after the Determination Notice to propose revisions to the terms of the Merger Agreement or make another proposal, and will have made its representatives reasonably available to negotiate in good faith with Brickell (to the extent Brickell desires to do so) with respect to such proposed revisions or other proposal, if any, and (3) after considering the results of any such negotiations and giving effect to the proposals made by Brickell, if any, after consultation with outside legal counsel, the Vical board of directors has determined, in good faith, that the failure to make the Vical Board of Directors Recommendation Change in response to such Vical Change in Circumstance could be inconsistent with the fiduciary duties of the Vical board of directors to Vical’s stockholders under applicable law. The provisions of the Merger Agreement

106.

described in this paragraph also apply to any material change to the facts and circumstances relating to such Vical Change in Circumstance and a new Determination Notice would be required following any such material change, except that the references to three business days in this paragraph would be deemed to be two business days.

Other Agreements

Regulatory Approvals

Each party agreed to use reasonable best efforts to file or otherwise submit, as soon as practicable after the date of the Merger Agreement, all applications, notices, reports and other documents reasonably required to be filed or submitted by such party with or to any governmental body with respect to the Contemplated Transactions, and to submit promptly any additional information requested by any such governmental body.

Director Indemnification and Insurance

The Merger Agreement provides that, for a period of six years following the effective time of the Merger, Vical and the combined company will, jointly and severally, indemnify and hold harmless each person who is, has been, or who becomes prior to the effective time, a director, officer, fiduciary or agent of Vical or Brickell or any of their respective subsidiaries, respectively, against all claims, losses, liabilities, damages, judgments, fines and reasonable fees, costs and expenses, including attorneys’ fees and disbursements, incurred in connection with any claim, action, suit, proceeding or investigation, whether civil, criminal, administrative or investigative, arising out of or pertaining to the fact that such person is or was a director, officer, fiduciary or agent of Vical or of Brickell, whether asserted or claimed prior to, at or after the effective time, in each case, to the fullest extent permitted under applicable law. Each such indemnitee will be entitled to advancement of expenses incurred in the defense of any such claim, action, suit, proceeding or investigation from each of Vical and the combined company, jointly and severally.

111.

The Merger Agreement also provides that the provisions relating to the indemnification, advancement of expenses and exculpation of present and former directors and officers of Vical set forth in Vical’s restated certificate of incorporation and bylaws will not be amended, modified or repealed for a period of six years from the effective time of the Merger in any manner that would adversely affect the rights of individuals who, at the effective time of the Merger, were officers or directors of Vical. After the closing of the Merger, the certificate of incorporation and bylaws of the surviving corporation will contain provisions at least as favorable as the provisions relating to the indemnification, advancement of expenses and exculpation of present and former directors and officers presently set forth in Vical’s restated certificate of incorporation and bylaws.

Vical has agreed to secure and prepay a six year “tail policy” on Vical’s existing directors’ and officers’ liability insurance policy with an effective date as of the closing date of the Merger.

112.

AGREEMENTS RELATED TO THE MERGER

Confidentiality Agreement

On February 4, 2019, Vical and Brickell entered into a confidentiality agreement (dated to be effective January 31, 2019), which contained a standstill provision, but permitted the counterparty to privately and confidentially approach our management during the standstill period, as well as other customary confidentiality obligations.

Support Agreements

Prior to the execution of the Merger Agreement, officers, directors and certain stockholders of Brickell, who collectively held approximately 75% of the voting power of Brickell’s outstanding capital stock as of June 2, 2019 and onan as-converted to common stock basis, entered into support agreements with Vical under which such stockholders agreed to, among other things, vote in favor of the adoption and approval of the Merger Agreement and the approval of the Merger and the other transactions contemplated by the Merger Agreement.

Lock-Up Agreements

Concurrently with the execution of the Merger Agreement, the officers, directors and certain other stockholders of Brickell also enteredinto lock-up agreements, pursuant to which such stockholders have agreed not to, except in limited circumstances, transfer or dispose of, any shares of Vical common stock received in the Merger or any securities convertible into, or exercisable or exchangeable for, shares of Vical common stock received in the Merger for a period of 180 days after the closing date of the Merger.

The Brickell stockholders whoexecuted lock-up agreements collectively held approximately 75% of the voting power of Brickell’s outstanding capital stock as of June 2, 2019 and onan as-converted to common stock basis.

The Vical stockholders did not executelock-up agreements in connection with the Merger.

Concurrent Financing; Funding Agreement

Concurrent with the execution of the Merger Agreement, Brickell and NovaQuest entered into the Funding Agreement pursuant to which NovaQuest committed, subject to the terms and conditions of the Funding Agreement, to provide up to $25.0 million in near-term research and development funding to Brickell in connection with sofpironium bromide in the Concurrent Financing, with $5.6 million of the commitment expected to be paid promptly following the closing of the Merger and the remaining portion of the commitment expected to be paid in quarterly payments equal to 67% of invoiced research and development expenses in connection with sofpironium bromide incurred during the following four fiscal quarters. Upon receipt of marketing approvals in the United States for sofpronium bromide, Brickell will be obligated to make certain milestone payments to NovaQuest totaling $37.5 million. Beginning in the fiscal quarter that is two years following the first commercial sale of a sofpronium bromide product, Brickell will be required to make low single digit revenue sharing payments based on annual net sales worldwide (except for Japan, China and certain other countries). Generally, if Brickell suspends or terminates its development program in respect of sofpironium bromide, Brickell will be required to pay NovaQuest $25.0 million plus interest of between 8% and 12%. However, in the event that Brickell terminates its development program for sofpromium bromide for certain reasons, including serious safety issues, a failure of the product’s Phase 3 studies, or the failure of FDA to approve the product, Brickell will not be obligated to make any payments to NovaQuest unless it subsequently resumes the development program.

113.

Under the Funding Agreement, Brickell makes various representations and warranties and commits to comply with various covenants. NovaQuest may terminate the Funding Agreement and terminate its obligation to make payments in the event of Brickell’s material uncured breach of a representation or covenant under the Funding Agreement. Brickell will also enter into a Security Agreement (the “Security Agreement”) with NovaQuest immediately following consummation of the Merger. Under the Security Agreement, NovaQuest will be able to exercise certain rights in the event of an event of default of the Funding Agreement. NovaQuest’s rights following an event of default include, among other things, foreclosing on Brickell’s assets in the United States relating to sofpironium bromide and, in certain circumstances, accelerating payment obligations under the Funding Agreement. NovaQuest also has the right to suspend its funding obligations under the Funding Agreement in the event of certain adverse developments relating to sofpironium bromide and in the event that certain of Brickell’s senior executives leave Brickell and we do not find replacements acceptable to NovaQuest. These provisions of the Funding Agreement are discussed in greater detail in the section titled “Risk Factors” in this proxy statement.

In connection with the Concurrent Financing, immediately following the closing of the Merger, Vical is obligated to issue the NovaQuest Warrants. The number of shares of the combined company’s common stock underlying the NovaQuest Warrants will be based on 10% warrant coverage on the $25.0 million commitment and the Exchange Ratio for the Merger, and the exercise price of the NovaQuest Warrants will be determined based on a 10% premium to the Brickell price per share of common stock implied in the Merger as adjusted for the Exchange Ratio.

The NovaQuest Warrants and the shares of common stock underlying the NovaQuest Warrants to be issued in the Concurrent Financing will be offered and sold in reliance on an exemption from registration under Regulation D promulgated under Section 4(a)(2) of the Securities Act. Appropriate restrictive legends will be affixed to the shares issued in the Concurrent Financing.

Determination of Executive Compensation

Brickell reviews compensation annually for all employees, including its named executive officers. In setting executive base salaries and bonuses and granting equity incentive awards, Brickell considers compensation for comparable positions in the market, the historical compensation levels of its executives, individual performance as compared to its expectations and objectives, its desire to motivate its employees to achieve short- and long-term results that are in the best interests of its stockholders, and a long-term commitment. Brickell does not target a specific competitive position or a specific mix of compensation among base salary, bonus or long-term incentives.

The compensation committee of Brickell’s board of directors has historically determined Brickell’s executive officers’ compensation. Brickell’s compensation committee typically reviews and discusses management’s proposed compensation with the Chief Executive Officer for all executives other than the Chief Executive Officer. In the case of the Chief Executive Officer, his individual performance evaluation is conducted by the compensation committee, which determines his base salary, cash bonus, and stock-based awards.

115.

In addition to corporate and individual goal achievement, the compensation committee also considers the following factors in determining an executive’s compensation package:

•

the executive’s role within Brickell and the compensation data for similar persons in peer group companies and subscription compensation survey data;

•

the demand for executives with the executive’s specific expertise and experience;

•

a comparison to other executives within Brickell having similar levels of expertise and experience; and

•

uniqueness of the executive’s industry skills.

Based on those discussions and its discretion, the compensation committee then recommends the compensation for each executive officer. Brickell’s compensation committee, without members of management present, discusses and ultimately approves the compensation of its executive officers.

In May 2019, the compensation committee of Brickell’s board of directors reviewed and considered a presentation by Compensia, Brickell’s compensation consultant, with respect to equity compensation grants made to Brickell’s employees and executive officers prior to the consummation of the Merger after taking into consideration industry standards following a review of the compensation practices of other publicpre-commercial stage biotechnology companies. As a result, the compensation committee recommended, and the Board approved, authorizing Brickell’s management to issue up to an aggregate of 2,607,274 stock options prior to the consummation of the Merger in order to retain Brickell’s current employees and executive officers. Brickell expects to grant 100,000 stock options each to Dennison Veru, William Ju, Charles Stiefel and George Abercrombie and 150,000 stock options to Reginald L. Hardy prior to the consummation of the Merger.

MATTERS BEING SUBMITTED TO A VOTE OF VICAL STOCKHOLDERS

PROPOSAL NO. 1:

APPROVAL OF THE AMENDMENT TO RESTATED CERTIFICATE OF INCORPORATION, AS AMENDED, OF VICAL EFFECTING THE REVERSE SPLIT

At the Special Meeting, Vical stockholders will be asked to approve an amendment to the restated certificate of incorporation, as amended, of Vical that will implement a reverse split of the issued shares of Vical common stock, at a ratio in the range of between one new share for every five shares and one new share for every fifteen shares outstanding (the “Reverse Split Charter Amendment”). Upon stockholder approval and in connection with the closing of the Merger, Vical and Brickell will mutually agree upon the exact reverse split ratio within that approved range. Upon the effectiveness of the Reverse Split Charter Amendment, or the split effective time, the issued shares of Vical common stock immediately prior to the split effective time will be reclassified into a smaller number of shares such that a Vical stockholder will own one new share of Vical common stock for the specified number of shares of issued common stock held by that stockholder immediately prior to the split effective time.

The Vical board of directors may determine to effect the Reverse Split, if it is approved by the stockholders, even if the other proposals to be acted upon at the meeting are not approved, including the consummation of a change of control of Vical resulting from the Merger.

The Reverse Split Charter Amendment, as more fully described below, will effect the Reverse Split but will not change the number of authorized shares of Vical common stock or preferred stock, or the par value of Vical common stock or preferred stock. The form of Reverse Split Charter Amendment is attached to this proxy statement as Appendix C.

Purpose

The Vical board of directors approved the proposal approving the Reverse Split Charter Amendment for the following reasons:

•

the Vical board of directors believes effecting the Reverse Split will cause the minimum bid price of Vical’s common stock to increase and may reduce the risk of a delisting of the Vical common stock (and the common stock of the combined company after the closing of the Merger) from Nasdaq in the future;

•

the Vical board of directors believes a higher stock price may help generate investor interest in Vical (and the combined company, after the closing of the Merger) and help the combined company attract and retain employees; and.

•

the requirements for listing on Nasdaq set forth below.

If the Reverse Split successfully increases the per share price of Vical common stock, Vical’s board of directors believes this increase may increase trading volume in Vical common stock and facilitate future financings by the combined company after the closing of the Merger, as well as enhance stockholder liquidity.

Nasdaq Requirements for Listing on the Nasdaq Capital Market

Vical common stock is listed on Nasdaq under the symbol “VICL.” Vical intends to file an initial listing application in the near term for the combined company with Nasdaq.

According to Nasdaq rules, an issuer must, in a case such as this, apply for initial inclusion following a transaction whereby the issuer combines witha non-Nasdaq entity, resulting in a change of control of the issuer

120.

and potentially allowingthe non-Nasdaq entity to obtain a Nasdaq listing. Accordingly, the listing standards of Nasdaq will require the combined company to have, among other things, a $4.00 per share minimum bid price upon the closing of the Merger. Therefore, the Reverse Split may be necessary in order to consummate the Merger.

One of the effects of the Reverse Split will be to effectively increase the proportion of authorized shares that are unissued relative to those that are issued. This could result in the combined company’s management being able to issue more shares without further stockholder approval. For example, before the Reverse Split, Vical’s authorized but unissued shares of common stock immediately prior to the closing of the Merger would be 50.0 million compared to shares issued of approximately 22.8 million. If Vical effects the Reverse Split using a 1 for 10 ratio, its authorized but unissued shares immediately prior to the closing of the Merger would be 50.0 million compared to shares issued of approximately 2.3 million. Vical currently has no plans to issue shares, other than in connection with the Contemplated Transactions, and to satisfy obligations under the Vical warrants and stock options (including those warrants and options assumed from Brickell in connection with the Merger and the NovaQuest Warrants to be issued following the Merger) from time to time as these warrants and options are exercised. The Reverse Split will not affect the number of shares of Vical capital stock that will continue to be authorized pursuant to the restated certificate of incorporation of Vical, as amended.

Potential Increased Investor Interest

On June 28, 2019, Vical common stock closed at $0.85 per share. An investment in Vical common stock may not appeal to brokerage firms that are reluctant to recommend lower priced securities to their clients. Investors may also be dissuaded from purchasing lower priced stocks because the brokerage commissions, as a percentage of the total transaction, tend to be higher for such stocks. Moreover, the analysts at many brokerage firms do not monitor the trading activity or otherwise provide coverage of lower priced stocks. Also, the Vical board of directors believes that many investment funds are reluctant to invest in lower priced stocks.

There are risks associated with the Reverse Split, including that the Reverse Split may not result in an increase in the market trading price of Vical common stock.

The history of similar reverse stock splits for companies in like circumstances is varied. There is no assurance that:

•

the market price per share of Vical common stock after the Reverse Split will rise in proportion to the reduction in the number of shares of Vical common stock outstanding before the Reverse Split;

•

the Reverse Split will result in a per share price that will attract brokers and investors who do not trade in lower priced stocks;

•

the Reverse Split will result in a per share price that will increase the ability of Vical (or the combined company, after the closing of the Merger) to attract and retain employees; or

•

the market price per share will be sufficient to list the common stock of the combined company on Nasdaq or will either exceed or remain in excess of the $1.00 minimum bid price as required by Nasdaq for continued listing thereafter.

The market price of Vical common stock will also be based on performance of Vical and other factors, some of which are unrelated to the number of shares outstanding. If the Reverse Split is effected and the market price of Vical common stock declines, the percentage decline as an absolute number and as a percentage of the overall market capitalization of Vical may be greater than would occur in the absence of a Reverse Split. Furthermore, the liquidity of Vical common stock could be adversely affected by the reduced number of shares that would be outstanding after the Reverse Split.

Principal Effects of the Reverse Split

The form of Reverse Split Charter Amendment is set forth in Appendix C to this proxy statement.

121.

The Reverse Split will be effected simultaneously for all outstanding shares of Vical common stock. The Reverse Split will affect all of the Vical stockholders uniformly and will not affect any stockholder’s percentage ownership interests in Vical, except to the extent that the Reverse Split results in any of the Vical stockholders owning a fractional share. Vical common stock issued pursuant to the Reverse Split will remain fully paid and nonassessable. The Reverse Split does not affect the total proportionate ownership of Vical following the Merger. The Reverse Split does not affect the total proportionate ownership of the combined company by Vical’s stockholders relative to Brickell’s stockholders following the Merger. The Reverse Split will not affect Vical’s continuing periodic reporting requirements of the the Exchange Act.

Determination of Reverse Stock Split Ratio

The ratio of the Reverse Split, if approved and implemented, will be a ratio of not less than1-for-5 and not more than1-for-15, as mutually agreed upon by Vical and Brickell. In determining the Reverse Split ratio, numerous factors will be considered, including:

•

the historical performance of the Vical common stock and the projected performance of the combined company’s common stock, assuming the Merger is consummated;

•

prevailing market conditions;

•

general economic and other related conditions prevailing in Vical’s industry and in the marketplace;

•

the projected impact of the selected Reverse Split ratio on trading liquidity in the combined company’s common stock and the ability to continue the listing of the combined company’s common stock on Nasdaq;

•

the capitalization of the combined company upon consummation of the Merger (including the number of shares of common stock issued and outstanding);

•

the prevailing trading price for the Vical common stock and the volume level thereof; and

•

potential devaluation of the market capitalization of the combined company as a result of a Reverse Split.

The purpose of asking for authorization to implement the Reverse Split at a ratio to be mutually agreed by Vical and Brickell, as opposed to a ratio fixed in advance, is to give Vical and Brickell the flexibility to take into account then-current market conditions and changes in price of the Vical common stock and to respond to other developments that may be deemed relevant when considering the appropriate ratio.

Procedure for Effecting the Reverse Split and Exchange of Stock Certificates

If the Vical stockholders approve the Reverse Split Charter Amendment, Vical will file the appropriate Reverse Split Charter Amendment with the Secretary of State of the State of Delaware at such time as the Vical board of directors has determined to be the appropriate split effective time. The Vical board of directors may delay effecting the Reverse Split without resoliciting stockholder approval. Beginning at the split effective time, each stock certificaterepresenting pre-split shares will be deemed for all corporate purposes to evidence ownership of post-split shares.

As soon as practicable after the split effective time, stockholders will be notified of the selected reverse split ratio and that the Reverse Split has been effected. Vical expects that the Vical transfer agent will act as exchange agent for purposes of implementing the exchange of stock certificates. If applicable, holdersof pre-split shares will be asked to surrender to the exchange agent stock certificatesrepresenting pre-split shares in exchange for stock certificates representing post-split shares in accordance with the procedures to be set forth in a letter of transmittal to be sent by Vical. No new certificates will be issued to a stockholder until such stockholder has surrendered such stockholder’s outstanding certificate(s) together with the properly completed and executed

122.

letter of transmittal to the exchange agent.Any pre-split shares submitted for transfer, whether pursuant to a sale or other disposition, or otherwise, will automatically be exchanged for post-split shares. Vical stockholders should not destroy any stock certificate(s) and should not submit any certificate(s) unless and until requested to do so.

Fractional Shares

No fractional shares will be issued in connection with the Reverse Split. Stockholders of record who otherwise would be entitled to receive fractional shares because they hold a numberof pre-split shares not evenly divisible by the numberof pre-split shares for which each post-split share is to be reclassified, will be entitled, upon surrender to the exchange agent of certificates representing such shares, to, with respect to each such fractional share, a cash payment in lieu thereof at a price equal to the fraction to which the stockholder would otherwise be entitled multiplied by the fair value per share of the common stock immediately prior to the split effective time as determined by the board of directors of Vical. The ownership of a fractional interest will not give the holder thereof any voting, dividend, or other rights except to receive payment therefor as described herein.

Stockholders should be aware that, under the escheat laws of the various jurisdictions where stockholders reside, where Vical is domiciled, and where the funds will be deposited, sums due for fractional interests that are not timely claimed after the effective date of the split may be required to be paid to the designated agent for each such jurisdiction, unless correspondence has been received by Vical or the exchange agent concerning ownership of such funds within the time permitted in such jurisdiction. Thereafter, stockholders otherwise entitled to receive such funds will have to seek to obtain them directly from the state to which they were paid.

By approving Proposal No. 1, the Vical stockholders will be: (a) approving a series of alternate amendments to Vical’s restated certificate of incorporation, as amended, pursuant to which any whole number of outstanding shares of common stock between and including 5 and 15 could be combined into one share of common stock; and (b) authorize Vical’s board of directors to file only one such amendment, as determined by Vical’s board of directors, and to abandon each amendment not selected by Vical’s board of directors, based upon the mutual agreement of Vical and Brickell. Vical in mutual agreement with Brickell may also elect not to undertake any Reverse Split and therefore abandon all amendments. However, effecting the Reverse Split is expected to be necessary to consummate the Merger.

Potential Anti-Takeover Effect

Although the increased proportion of unissued authorized shares to issued shares could, under certain circumstances, have an anti-takeover effect, for example, by permitting issuances that would dilute the stock ownership of a person seeking to effect a change in the composition of the Vical board of directors or contemplating a tender offer or other transaction for the combination of Vical with another company, the Reverse Split proposal is not being proposed in response to any effort of which Vical is aware to accumulate shares of Vical common stock or obtain control of Vical, other than in connection with the Merger, nor is it part of a plan by management to recommend a series of similar amendments to the Vical board of directors and stockholders. Other than the proposals being submitted to the Vical stockholders for their consideration at the Special Meeting, the Vical board of directors does not currently contemplate recommending the adoption of any other actions that could be construed to affect the ability of third parties to take over or change control of Vical. For more information, please see the section titled “Risk Factors” contained in the Vical10-K, which is incorporated in this proxy statement by reference.

Certain Material U.S. Federal Income Tax Consequences of the Reverse Split to U.S. Holders

The following is a discussion of certain material U.S. federal income tax consequences of the Reverse Split to certain U.S. Holders (as defined below) of Vical common stock but does not purport to be a complete analysis

123.

of all potential tax effects. This discussion is based on provisions of the Code, Treasury Regulations thereunder and administrative rulings, court decisions and other legal authorities related thereto, each as in effect as of the date of this proxy statement and all of which are subject to change or differing interpretations. Any such change or differing interpretation, which may or may not be retroactive, could alter the tax consequences to the Vical stockholders described herein. In addition, there can be no assurance that the Internal Revenue Service will not take a contrary position to the tax consequences described herein or that such position would not be sustained by a court. This discussion is included for general informational purposes only and does not purport to consider all aspects of U.S. federal income taxation that might be relevant to a U.S. Holder.

The discussion below only addresses the Vical stockholders who hold Vical common stock as a capital asset within the meaning of Section 1221 of the Code (generally property held for investment). It does not address all aspects of U.S. federal income tax that may be relevant to a Vical stockholder in light of such stockholder’s particular circumstances or to a stockholder subject to special rules, such as stockholders who are not U.S. Holders (as defined below), brokers or dealers in securities or foreign currencies, regulated investment companies, real estate investment trusts, traders who mark to market, financial institutions or insurance companies, mutual funds, stockholders holding their stock through individual retirement or othertax-deferred accounts,tax-exempt organizations, stockholders holding their stock as “qualified small business stock” pursuant to Section 1202 of the Code or as Section 1244 stock for purposes of the Code, stockholders who acquired their stock in connection with the exercise of warrants, stock options or stock purchase plans or other employee plans or compensatory arrangements, stockholders whose functional currency is not the U.S. dollar, partnerships or other pass-through entities or securityholders, members or partners in such entities, stockholders who hold their stock as part of an integrated investment (including a “straddle,” a pledge against currency risk, a hedge or other “constructive” sale or “conversion” transaction) comprised of shares of Vical common stock and one or more other positions, stockholders who exercise dissenters’ or appraisal rights, stockholders required to accelerate the recognition of any item of gross income with respect to their stock as a result of such income being recognized on an applicable financial statement (within the meaning of Section 451 of the Code), or stockholders who may have acquired their stock in a transaction subject to the gain rollover provisions of Section 1045 of the Code. In addition, this summary does not address any tax consequences other than certain U.S. federal income tax consequences of the Reverse Split, including the tax consequences of the Reverse Split under state, local ornon-U.S. tax laws or under estate, gift, excise or othernon-income tax laws, the alternative minimum tax, the Medicare contribution tax on net investment income, the tax consequences of transactions effectuated prior or subsequent to, or concurrently with, the Reverse Split (whether or not any such transactions are consummated in connection with the Reverse Split) including, without limitation, the receipt of payments under any retention bonus plan, the conversion of any convertible notes or the tax consequences to holders of options, warrants or similar rights to acquire Vical common stock.

For purposes of this discussion, a “U.S. Holder” means a beneficial owner of shares of Vical common stock that is any of the following:

•

an individual citizen or resident of the United States or someone treated as a U.S. citizen or resident for U.S. federal income tax purposes;

•

a corporation (or other entity treated as a corporation for U.S. federal income tax purposes) created or organized in or under the laws of the United States, any state thereof, or the District of Columbia;

•

an estate, the income of which is subject to U.S. federal income taxation regardless of its source; or

•

a trust if (i) a U.S. court can exercise primary supervision over the trust’s administration and one or more U.S. persons are authorized or have the authority to control all substantial decisions of the trust or (ii) it has a valid election in effect under applicable U.S. Treasury Regulations to be treated as a U.S. person.

124.

STOCKHOLDERS SHOULD CONSULT THEIR TAX ADVISORS WITH RESPECT TO THE APPLICATION OF THE U.S. FEDERAL INCOME TAX LAWS TO THEIR PARTICULAR SITUATIONS AS WELL AS ANY TAX CONSEQUENCES OF THE REVERSE SPLIT ARISING UNDER THE U.S. FEDERAL ESTATE OR GIFT TAX LAWS OR UNDER THE LAWS OF ANY STATE, LOCAL ORNON-U.S. TAXING JURISDICTION OR UNDER ANY APPLICABLE INCOME TAX TREATY.

Tax Consequences of the Reverse Split

We intend to treat the Reverse Split as a “recapitalization” for U.S. federal income tax purposes. As a result, a U.S. Holder generally should not recognize gain or loss upon the Reverse Split, except with respect to cash received in lieu of a fractional share of Vical common stock, as discussed below. A U.S. Holder’s aggregate tax basis in the shares of Vical common stock received pursuant to the Reverse Split should equal the aggregate tax basis of the shares of the Vical common stock surrendered (excluding any portion of such basis that is allocated to any fractional share of Vical common stock), and such U.S. Holder’s holding period in the shares of Vical common stock received should include the holding period in the shares of Vical common stock surrendered. Treasury Regulations provide detailed rules for allocating the tax basis and holding period of the shares of Vical common stock surrendered to the shares of Vical common stock received in a recapitalization pursuant to the Reverse Split. U.S. Holders who acquired shares of Vical common stock on different dates and at different prices should consult their tax advisors regarding the allocation of the tax basis and holding period of such shares.

Cash in Lieu of Fractional Shares

A U.S. Holder that receives cash in lieu of a fractional share of Vical common stock pursuant to the Reverse Split is expected to recognize capital gain or loss in an amount equal to the difference between the amount of cash received and the U.S. Holder’s tax basis in the shares of Vical common stock surrendered that is allocated to such fractional share of Vical common stock. Such capital gain or loss should be long-term capital gain or loss if the U.S. Holder’s holding period for Vical common stock surrendered exceeded one year at the effective time of the Reverse Split.

Information Reporting and Backup Withholding

A U.S. Holder may be subject to information reporting and backup withholding on cash paid in lieu of fractional shares in connection with the Reverse Split. A U.S. Holder will be subject to backup withholding if such holder is not otherwise exempt and such holder does not provide its taxpayer identification number in the manner required or otherwise fails to comply with applicable backup withholding tax rules.

Backup withholding is not an additional tax. Any amounts withheld under the backup withholding rules may be refunded or allowed as a credit against a U.S. Holder’s federal income tax liability, if any, provided the required information is timely furnished to the IRS. U.S. Holders should consult their tax advisors regarding their qualification for an exemption from backup withholding and the procedures for obtaining such an exemption.

126.

PROPOSAL NO. 2:

APPROVAL OF THE CHANGE OF CONTROL OF VICAL RESULTING FROM THE CONTEMPLATED TRANSACTIONS PURSUANT TO THE NASDAQ RULES

At the Special Meeting, Vical stockholders will be asked to approve the change of control of Vical resulting from the Merger pursuant to the Nasdaq rules.

Immediately following the Merger, assuming the Vical Net Cash is at least $34.2 million (and not more than $35.2 million) and the Brickell Net Working Capital is at least -$10.2 million (and not more than -$9.2 million), the former Brickell securityholders and NovaQuest, collectively, are expected to own, subject to adjustment, approximately 60% of the aggregate number of shares of Vical common stock, and the securityholders of Vical as of immediately prior to the Merger are expected to own, subject to adjustment, approximately 40% of the aggregate number of shares of Vical common stock (in each case on a fully diluted basis using the treasury stock method in instances other than with respect to the NovaQuest Warrants and certain equity issuances by Brickell following the signing of the Merger Agreement and prior to the completion of the Merger). Changes in the amount of the Vical Net Cash and the Brickell Net Working Capital could result in relative ownership percentages that are different than those described above.

The terms of, reasons for and other aspects of the Merger Agreement, the Merger and the issuance of Vical common stock in the Contemplated Transactions are described in detail in the other sections in this proxy statement. A copy of the Merger Agreement is attached as Appendix A to this proxy statement and is incorporated by reference.

Under Nasdaq Listing Rule 5635(a)(1), a company listed on Nasdaq is required to obtain stockholder approval prior to the issuance of common stock, among other things, in connection with the acquisition of another company’s stock, if the number of shares of common stock to be issued is in excess of 20% of the number of shares of common stock then outstanding. The potential issuance of up to 55,596,573 shares of Vical common stock in the Merger (including to Brickell stockholders, and with respect to Brickell options, Brickell warrants, the NovaQuest Warrants and the issuance of up to $12.5 million in convertible notes and related warrants at 50% coverage, to acquire 2,493,665 shares of common stock (based on the estimated price per share of Brickell common stock implied in the Merger)) requires the approval of Vical’s stockholders under the Nasdaq Listing Rules. Accordingly, in order to ensure compliance with Nasdaq Listing Rule 5635(a)(1), Vical must obtain the approval of Vical’s stockholders for the issuance of these securities in the Merger.

Required Vote

If a quorum is present, the affirmative vote of a majority of the votes cast in person or by proxy at the Special Meeting is required to approve the change of control of Vical resulting from the Contemplated Transactions pursuant to the Nasdaq rules. Abstentions and broker non-votes will be not be considered votes cast and will have no effect on the vote for this Proposal No. 2. It is anticipated that this Proposal No. 2 will be a non-discretionary proposal considered non-routine under the rules of the NYSE.

DESCRIPTION OF VICAL’S BUSINESS

In addition to the information set forth below, please refer to the Vical 10-K and the Vical Quarterly Reports on Form 10-Q for the quarters ended March 31, 2019 and June 30, 2019, and the other documents filed with the SEC and incorporated by reference into this proxy statement for additional information regarding our business.

Overview

Vical was incorporated in April 1987 as a Delaware corporation and has devoted substantially all of its resources since that time to the research and development of biopharmaceutical products, including those based on its patented DNA delivery technologies for the prevention and treatment of serious or life-threatening diseases. Vical has a completed preclinical program, with an allowed investigational new drug application (IND) using its CyMVectin prophylactic vaccine formulated with its Vaxfectin adjuvant to prevent CMV infection before and during pregnancy.

Product Development

In March 2015, Vical entered into a license agreement with Astellas Pharma Inc. (“Astellas”), granting Vical exclusive worldwide license to develop and commercialize, including the exclusive right to Astellas patents which claim the composition of matter of, and methods of making or using,VL-2397.VL-2397 represents a potential new class of antifungal compound to address invasive aspergillus infections, which are major causes of morbidity and mortality in immunocompromised patients, including transplant. In preclinical studies to date, it has demonstrated faster fungicidal activity than marketed drugs and activity againstazole-resistant fungal pathogens. Current treatment options have limited efficacy, as approximately50-60% of allogeneic hematopoietic stem cell transplant recipients with invasive aspergillosis infections die within 12 weeks. Over the past 30 years, only one new class of antifungal drugs (echinocandins) has been introduced.

The U.S. FDA has advised thatVL-2397 would be eligible for a Limited Use Indication (LUI) approval assuming a successful outcome of a single Phase 2 trial carried out in accordance with a protocol and statistical analysis plan consistent with the Agency’s advice. The final determination whether the drug is approvable will be made by FDA after review of all relevant data. The LUI is a provision of the Limited Population Pathway established under the 21st Century Cures Act of 2016. In the case ofVL-2397, the LUI approval would be for patients for whom alternative regimens are not available to treat their invasive aspergillosis. A Phase 3 trial would be required to support full approval ofVL-2397 for the treatment of invasive aspergillosis in a broader population. The FDA has granted Vical Qualified Infectious Disease Product (QIDP), Orphan Drug and Fast Track designations forVL-2397 in the treatment of invasive aspergillosis.

About Invasive Aspergillosis

Invasive aspergillosis is a life-threatening infection that typically affects immunocompromised patients, including those with acute leukemia and recipients of allogeneic HCT or lung transplants. Infection typically starts in the lungs and rapidly disseminates to other tissues. An estimated 200,000 cases of invasive aspergillosis are diagnosed annually worldwide.

Intellectual Property

All of the Astellas issued U.S. patents and foreign counterparts expired on March 13, 2019. Vical is the sole assignee of issued U.S. patents covering numerous examples of cationic lipid compounds that are used to

129.

facilitate delivery of plasmids to some tissues. Vical’s Vaxfectin^® adjuvant are protectedin-part by lipid technology and/or lipid compound patents that extend up to March 24, 2020. Patent protection of these key lipids also has been obtained in Europe, Canada and Japan. Under the Hatch-Waxman Act, a U.S. patent term extension for up to 5 years may be available under certain conditions.

Property

Vical occupies approximately 17,000 square feet of research laboratory and office space at a single site in San Diego, California through a sublease with Genopis, Inc. ending on December 31, 2019.

Legal Proceedings

Vical is unaware of any lawsuits presently pending against Vical which, individually or in the aggregate, are deemed to be material to its financial condition or results of operations.

DESCRIPTION OF BRICKELL’S BUSINESS

Overview

Brickell is a clinical-stage pharmaceutical company focused on developing innovative and differentiated prescription therapeutics for the treatment of debilitating skin diseases. Brickell’s pipeline consists of potential novel therapeutics for hyperhidrosis, cutaneousT-cell lymphoma, psoriasis, and other prevalent dermatological conditions. Brickell believes that Brickell’s portfolio of product candidates targets significant market opportunities where innovative therapies are needed. Brickell’s executive management team and board of directors bring extensive experience in product development and global commercialization, having served in leadership roles at large global pharmaceutical companies and biotechs that have developed and/or launched successful products, including several that werefirst-in-class and/or achieved iconic status, such as Cialis^®, Taltz^®, Gemzar^®, Prozac^®, Cymbalta^® and Juvederm^®. Brickell’s strategy is to leverage this experience toin-license, acquire, develop and commercialize innovative products that Brickell believes can be successful in the currently underserved dermatology global marketplace.

Brickell’s pivotal Phase3-ready clinical-stage product candidate, sofpironium bromide, is a new molecular entity and “soft” drug that belongs to a class of medications called anticholinergics. Anticholinergics block the action of acetylcholine, a chemical that transmits signals within the nervous system that are responsible for a range of bodily functions, including activation of the sweat glands. Soft drugs, such as sofpironium bromide, exert their action topically and are rapidly metabolized once absorbed into the blood. This mechanism of action may allow for highly effective doses to be used while limiting systemic side effects. Brickell is developing sofpironium bromide as a potentialbest-in-class, self-administered, once-daily, topical therapy for the treatment of primary axillary hyperhidrosis. Hyperhidrosis is a life-altering condition of sweating beyond what is physiologically required to maintain normal thermal regulation, is believed to be caused by an overactive cholinergic response of the sweat glands, and affects an estimated 15.3 million, or 4.8%, of the United States (U.S.) population. According to a 2016 update on the prevalence and severity of hyperhidrosis in the United States by Doolittle et al., axillary (underarm) hyperhidrosis, which is the targeted first indication for sofpironium bromide, is the most common occurrence of hyperhidrosis, affecting 65% of patients in the United States or an estimated 10 million individuals.

Brickell and Brickell’s development partner, Kaken, have conducted 19 Phase 1 and Phase 2 clinical studies of sofpironium bromide gel that encompass over 1,200 subjects. These studies have evaluated the safety, tolerability, pharmacokinetics (PK), and efficacy of sofpironium bromide gel in adult and pediatric primary axillary hyperhidrosis patients and healthy adult subjects. In addition, Kaken reported positive pivotal Phase 3 results, achieving statistical significance on all primary and secondary endpoints, in its clinical study conducted in Japan in March 2019. Based on the positive results achieved from three completed Phase 2b clinical trials (two in the U.S. and one in Japan by Kaken), Kaken’s recently completed pivotal Phase 3 clinical trial in subjects with primary axillary hyperhidrosis in Japan, as well as Brickell’s ongoing fully-enrolled Phase 3 long-term safety study in 300 subjects with primary axillary hyperhidrosis in the U.S., Brickell intends to initiate two pivotal Phase 3 clinical trials in approximately 450 subjects per study with primary axillary hyperhidrosis in the U.S. in the fourth quarter of 2019 with the goal of submitting a New Drug Application (“NDA”) to the FDA. Brickell expects to obtain results from the pivotal Phase 3 clinical trials in the fourth quarter of 2020.

Brickell’s second product candidate,BBI-3000, is a selective, potentially highly tolerable and potent novel retinoid X receptor (RXR) agonist being developed for the oral treatment of cutaneousT-cell lymphoma (“CTCL”). Retinoids are derivatives of vitamin A that play a pivotal role in a diverse group of biologic processes including, but not limited to, cellular proliferation, differentiation, apoptosis, and development. The biological activity and tolerability of retinoids depends in part on the binding availability to RAR and RXR receptors. There are several topical and oral retinoids currently on the market that have shown efficacy in the treatment of several skin conditions, such as CTCL (e.g., bexarotene/Targretin^®), acne and psoriasis (e.g., tazarotene, adapalene and tretinoin).BBI-3000 currently is being tested by the National Cancer Institute (NCI) in two Phase 1 clinical

131.

studies as a chronic, orally-administered chemoprevention agent for breast cancer. The product candidate has been well tolerated in the NCI investigations conducted to date, providing an encouraging signal of the potential overall favorable systemic safety profile ofBBI-3000 for CTCL. Brickell is targeting the initiation of aproof-of-concept clinical study withBBI-3000 for CTCL in late 2020.

Brickell’s third product candidate,BBI-6000, is a novel retinoic acid-related orphan nuclear receptor gamma (RORg) inhibitor that Brickell is developing for the topical treatment ofmild-to-moderate psoriasis. RORg inhibition targets the pathway of a validated cytokine(IL-17) that has been implicated in the pathogenesis of psoriasis. Monoclonal antibodies targetingIL-17 have recently shown significant efficacy in the treatment of psoriasis, and Brickell is planning to developBBI-6000 as a topically applied, potent and selective small-molecule therapeutic targeting this pathway.BBI-6000 is currently in the preclinical stages of development, and upon completion of the required Investigational New Drug (“IND”)-enabling studies, Brickell intends to commence aproof-of-concept clinical trial in patients withmild-to-moderate psoriasis in early 2021.

Brickell also has early-stage research programs targeting other prevalent skin diseases, such as androgenic alopecia and allergic contact dermatitis.

Brickell’s Strategy

Brickell’s strategy is toin-license, acquire, develop and commercialize innovative and differentiated medical dermatology products that Brickell believes can be successful in the dermatology marketplace to transform lives by solving currently unmet patient needs. The key components of Brickell’s patient-focused strategy are to:

Rapidly advance Brickell’s lead late-stage product candidate, sofpironium bromide, through pivotal Phase 3 clinical trials and engage with patients and members of the dermatology community.Brickell believes that its management team’s expertise in designing and executing product development programs in dermatology, combined with the relative efficiencies of dermatology product development, will enable Brickell to advance sofpironium bromide rapidly through pivotal Phase 3 clinical trials. If approved, Brickell intends to promote awareness of sofpironium bromide, and also the disease being targeted, among key opinion leaders, including prescribing dermatologists and pediatricians, patient advocacy groups like the International Hyperhidrosis Society, and directly to patients and their families coping with primary axillary hyperhidrosis. Consumer activation through a variety of media will be essential to educate patients regarding hyperhidrosis and the benefits associated with a safe, effective, and differentiated treatment option for this debilitating condition.

Efficiently establishproof-of-concept for Brickell’s existing early-stage dermatology product candidates and rapidly progress promising candidates into late-stage clinical development. Brickell seeks to establish quickly and efficientlyproof-of-concept for Brickell’s early-stage product candidates, includingBBI-3000 andBBI-6000. Brickell intends to progress these product candidates through the requiredIND-enabling studies, followed by initiation ofproof-of-concept clinical trials forBBI-3000 andBBI-6000 in late 2020 and early 2021, respectively. Brickell also owns and/or has intellectual property rights to early-stage research programs targeting other prevalent skin diseases, and Brickell’s objective is to pursue development of these early-stage product candidates selectively with a strong focus on large and untapped patient populations with significant unmet medical needs. Brickell believes it will be able to advance product candidates expeditiously into the next stages of development by leveraging the extensive global pharmaceutical experience of Brickell’s management team across multiple functional areas.

In-license and acquire new product candidates and, potentially, commercial-stage products while maintaining strong relationships with Brickell’s current strategic partner.Since Brickell’s founding in 2009, Brickell has executed numerous transactions with low upfront costs and favorable low royalty obligations, resulting in its promising product candidate portfolio. Brickell intends to continue to identify, evaluate,in-license and acquire attractive product candidates at the right level of investment from a variety of strategic sources.In

132.

2015, Brickell entered into anout-license transaction with Kaken, for the development and commercialization of sofpironium bromide in Japan and certain other Asian countries. Brickell expects to continue to engage with Kaken and further develop Brickell’s strong global partnership to create value for sofpironium bromide in the U.S., Japan and other countries.

Continue to expand Brickell’s team of enthusiastic, committed, and experienced professionals. Brickell will continue to expand its team by identifying and hiring dedicated, talented, experienced, and patient-centric employees who align with Brickell’s culture, values, and patient-centric mission and can make significant contributions to the combined company.

Product Candidates

Brickell’s current portfolio of product candidates, all of which are new molecular entities accompanied with intellectual property rights, are summarized in the following chart:

Sofpironium Bromide for the Potential Treatment of Hyperhidrosis

Sofpironium bromide is a pivotal Phase3-ready potentiallybest-in-class topical, small-molecule soft-anticholinergic product candidate Brickell is developing for once-daily treatment of primary axillary hyperhidrosis in adults and teens. Sofpironium bromide was designed as a structural analog of a well-known potent anticholinergic, glycopyrrolate, to achieve its therapeutic effect at the application site (skin) similar to glycopyrrolate. However, it differs from glycopyrrolate in that sofpironium bromide includes aneasy-to-metabolize moiety, or part of a molecule, that results in rapid deactivation of the compound when it reaches systemic circulation. This soft drug design may, therefore, result in a meaningful reduction of the potentially undesirable systemic anticholinergic side effects while potentially maintaining and/or improving upon the intended anticholinergic efficacy.

Hyperhidrosis is a debilitating life-altering skin disorder of chronic excessive sweating beyond what is necessary for thermoregulation of the body. Current estimates show that primary hyperhidrosis (excessive sweating without an alternative origin) affects approximately 4.8% of the U.S. population, or roughly 15.3 million people, with the prevalence highest (8.8%) among the U.S. population ages 18–39. Of these individuals, 70% report severe excessive sweating that they cannot control or shut off in at least one body area. The most common area is the underarms (axilla), followed by the face (42%), palms of the hands (40%), and the

133.

soles of the feet (38%). It is estimated that nearly half (49%) of people with hyperhidrosis have not discussed their condition with a healthcare professional, either because they do not yet know it is a medical condition or believe that no adequate treatment options exist. Furthermore, in one survey 75% of subjects with hyperhidrosis said that it has had negative impacts on their professional and social lives, sense of well-being, and emotional and mental health. Brickell believes that, due to the lack of diagnosis and available treatment options, and general lack of knowledge about the disease, hyperhidrosis presents a substantial market opportunity for a new, innovative, effective, well-tolerated, topical treatment. Brickell believes such a therapy could not only further penetrate the segment of patients who currently seek treatment from a physician, but also encourage more patients to seek treatment for this condition that causes them to deal with (and try to hide) it each and every day.

Brickell and Kaken have conducted 19 Phase 1 and Phase 2 clinical studies of sofpironium bromide gel that encompass over 1,200 subjects. These studies have evaluated the safety, tolerability, pharmacokinetics (PK), and efficacy of sofpironium bromide gel in adult and pediatric primary hyperhidrosis patients and healthy adult subjects. In addition, Kaken has reported positive pivotal Phase 3 results, achieving statistical significance on all primary and secondary endpoints, in its clinical study conducted in Japan in March 2019. Based upon the positive results achieved from three completed Phase 2b clinical trials (two in the U.S. and one in Japan via Kaken), Kaken’s recently completed pivotal Phase 3 clinical trial in subjects with primary axillary hyperhidrosis in Japan, as well as Brickell’s ongoing fully-enrolled Phase 3 long-term safety study in 300 subjects with primary axillary hyperhidrosis in the U.S., Brickell intends to initiate two pivotal Phase 3 clinical trials in approximately 450 subjects per study with primary axillary hyperhidrosis in the U.S. in the fourth quarter of 2019. Brickell expects to obtain results from the pivotal Phase 3 clinical trials in the fourth quarter of 2020.

The prior positive results, coupled with an attractive and significant market opportunity, reinforce Brickell’s confidence in sofpironium bromide as a potentialbest-in-class new prescription treatment option for the millions of people in the U.S., Japan and other countries, suffering daily on a chronic basis with axillary hyperhidrosis.

Current Hyperhidrosis Treatment Options and Limitations

The market for products to control sweating is large and highly underpenetrated by innovative prescription pharmaceutical products thoroughly tested in clinical trials. More specifically, current hyperhidrosis treatment options generally fall into one of the following categories:

•

Self-administered topicals, which include topical antiperspirants containing metal salts that block the release of sweat to the skin surface by clogging the opening of the duct and Qbrexza (glycopyrronium), approved in June 2018 by the FDA for the topical treatment of primary axillary hyperhidrosis in adults and pediatric patients nine years of age and older. For decades, topical antiperspirants containing metal salts have been the most widely used treatment option for hyperhidrosis.Over-the-counter (“OTC”) antiperspirants contain low concentrations of metal salts and are generally well-tolerated but limited in efficacy. Prescription antiperspirants containing higher concentrations of metal salts are typically recommended as the treatment of choice when OTC antiperspirants are ineffective. However, these are only marginally more effective, and their tolerability is limited by skin irritation associated with increased metal salt concentrations, which react with water to form irritating hydrochloric acid on the skin. Qbrexza is administered by prescription using asingle-use clothpre-moistened with the active ingredient, 2.4% glycopyrronium solution, packaged in individual pouches. Qbrexza inhibits the action of acetylcholine on sweat glands, thereby reducing sweating. While Qbrexza has shown to be effective in treating hyperhidrosis in certain subjects, Brickell believes that there is room for improved and more sustained efficacy, as well as products that may potentially result in a lower incidence of unwanted systemic anticholinergic side effects including, but not limited to, dry mouth, blurred vision, and urinary hesitancy.

•

Injectable, systemic, and other treatments that block activation of the sweat glands. Therapeutic options for patients who are not satisfied with topical therapies are largely limited to more cumbersome or invasive treatment strategies directed to either blocking the activation of, destroying, or removing

134.

the sweat glands. Intradermal injections of botulinum toxin, or BOTOX^®, a neurotoxin that blocks the release of acetylcholine, are effective but can be painful, costly, and must be administered by a physician with patients receiving on average 20 to 30 injections to each arm pit every six to nine months. A microwave device, MiraDry^®, is designed to overheat and destroy sweat glands. However, treatment can: be painful, require multiple physician visits, cause destruction of the sweat gland and is not generally covered by insurance. All these treatments are time-consuming and require a significant investment of physician training and administration time and, in the case of microwave treatment, capital investment by the treating physician. As a result, these treatments have limited attractiveness both to doctors and their patients. Furthermore, they are also not approved or well-suited for application to the hands or feet. In contract, we believe sofpironium bromide may be developed for hands and feet. Iontophoresis, which involves soaking the hands or feet in water through which an electrical current is passed, can be performed in a physician’s office or at home, but requires repeated, time-consuming and often bothersome treatments.

•

Surgical and other procedures intended to destroy or remove sweat glands. Some patients with severe hyperhidrosis may choose to be treated with invasive surgical techniques that involve removal of sweat glands or destruction of nerves that transmit activating signals to the glands. Surgery is a significant and costly permanent undertaking that can be associated with numerous severe side effects, including increased compensatory sweat production in other body areas.

Deciding among these available treatments depends on many factors including the affected area, severity of the disease and impact on the patient’s quality of life due to the disease being uncontrolled.

Brickell’s Potential Hyperhidrosis Solution

As a result of the limitations of these currently available treatment options, Brickell believes that there is a significant unmet patient need for a new, effective, safe, well-tolerated, self-administered, prescription topical hyperhidrosis therapy. To address this need, Brickell is developing sofpironium bromide gel, a soft anticholinergic for the once-daily topical prescription treatment of hyperhidrosis. Soft drugs are designed to provide maximal therapeutic effect with a favorable safety and tolerability systemic profile.

Key attributes of a soft drug include:

•

The synthesis of a soft drug is achieved by starting with a known inactive metabolite of a known active drug (e.g., glycopyrrolate).

•

The inactive, or less active, metabolite is then structurally modified to an active form that will undergo a predictableone-step transformation back into the inactive metabolite in vivo.

•

Thus, the soft drug concept is based upon predictable metabolic deactivation processes by enzymes found predominantly in the systemic circulation.

Brickell believes that soft-anticholinergic, such as sofpironium bromide, that exerts its action topically and is rapidly metabolized into a less active metabolite when it reaches circulation can allow delivery of potentially effective doses without the limiting systemic side effects.

Clinical Development of Sofpironium Bromide for Primary Axillary Hyperhidrosis

Phase 1 and Phase 2 Clinical Trials

Brickell, together with Brickell’s partner Kaken, has conducted 19 Phase 1 and Phase 2 clinical studies of sofpironium bromide gel that encompass over 1,200 subject exposures. These studies have evaluated the safety, tolerability, PK, and efficacy of sofpironium bromide gel in adult and pediatric primary hyperhidrosis patients and healthy adult subjects.

135.

In clinical studies conducted to date, all three concentrations of sofpironium bromide gel tested (5%, 10%, and 15%) were safe and tolerable. Treatment-emergent adverse events (TEAEs) were mostly mild or moderate in severity. No deaths or serious adverse reactions have been reported in any clinical studies with sofpironium bromide gel. Six serious adverse events have been reported and all were determined to be unrelated to sofpironium bromide gel administration. Consistent with the soft drug design, a low incidence of systemic anticholinergic adverse events (AEs) has been found in all clinical studies of sofpironium bromide gel. The most common anticholinergic AE was dry mouth, and all anticholinergic AEs observed were expected. Of note, the anticholinergic AEs were predominantly mild or moderate in severity and transient in duration (i.e., resolving gradually with continued use). All TEAEs completely resolved spontaneously with treatment discontinuation. Local application site tolerability reactions of burning, itching, pain, erythema, and dryness at the axillae were predominantly minimal in severity and typically transient.

Overall, all three sofpironium bromide gel concentrations, 5%, 10%, and 15%, exhibited a larger absolute mean reduction in gravimetric sweat production (“GSP”) from baseline to end of treatment (“EOT”) compared with vehicle. Better improvement in GSP response was associated with higher concentrations of sofpironium bromide. However, while there was a slight trend toward dose response, all gel concentrations were essentially similar in patient-reported outcome measures based on the Hyperhidrosis Disease Severity Measure-Axillary(“HDSM-Ax”), Dermatology Life Quality Index (“DLQI”), and Hyperhidrosis Disease Severity Score (“HDSS”). The response was seen as early as Day 8 and remained consistent throughout the applicable treatment period.

Confirmatory Phase 2b Clinical Trial(BBI-4000-CL-203)

The confirmatory Phase 2b clinical study was a multicenter, randomized, double blind, vehicle-controlled clinical trial to evaluate the safety and efficacy of topically-applied sofpironium bromide gel, 5%, 10%, and 15%, in subjects with primary axillary hyperhidrosis. The study enrolled a total of 227 subjects across 23 clinical sites in the U.S, with subjects randomized to one of Brickell’s cohorts, either sofpironium bromide gel, 5% (n=57), 10% (n=57), 15% (n=56), or vehicle gel (placebo; n=57) and applied the assigned product to the axillae (underarms) once daily, at bedtime, for 42 days. The objectives of this study were to evaluate (1) the effect of sofpironium bromide gel, 5%, 10%, and 15% on hyperhidrosis disease severity as it relates toHDSM-Ax, GSP, HDSS, and DLQI; and (2) the safety and local tolerability of sofpironium bromide gel, 5%, 10%, and 15%.

Changes inHDSM-Ax measures indicated statistically significant responses in all dose groups with all methods of analysis. Statistically significant differences were observed as early as Day 8 and were sustained over time. A significant proportion of subjects had at least a2-point change from baseline to EOT inHDSM-Ax-7 items scale (5% gel: 47.4%, p=0.0122; 10% gel: 47.4%, p=0.0169; 15% gel: 53.7%, p=0.0025; vehicle: 24.6%). Larger absolute mean reductions in GSP from baseline to EOT were found for all sofpironium bromide gel concentrations compared to vehicle gel. Treatment with sofpironium bromide gel, 15% (pivotal Phase 3 active dose group) resulted in statistically significant reduction in GSP from baseline to EOT(-219 mg, p=0.01; vehicle-151.63). Consistently superior ranked values were determined for sofpironium bromide, 15% in comparison to other sofpironium bromide gel groups and vehicle. The ranked order analysis does not indicate a response for the vehicle, thus indicating the improvement is real and not observed by chance. All sofpironium bromide gel groups met the secondary efficacy endpoints for HDSS and DLQI.

Among the safety population (includes all subjects who received study drug at least once; n=225), the incidence of TEAEs was relatively low (32%), with a higher incidence in the 15% gel group (51.9%) compared to the other groups (5% gel, 29.8%; 10% gel, 33.6%; vehicle gel, 15.8%). A total of 177 TEAEs were reported by 73 subjects. The most common AEs included dry mouth (14.2%) and blurred vision (5.8%). Observed systemic TEAEs were consistent with known adverse effects of drugs of this class (i.e., anticholinergic activity). All TEAEs resolved spontaneously with treatment discontinuation. One SAE was reported, which was not related to the study drug. Treatment in all dose groups was well-tolerated. The majority of subjects (³ 91%) in all sofpironium bromide gel dose groups reported absent, minimal or mild itching and burning at any time point.

136.

Investigator tolerability assessments rated as absent, minimal or mild for at least 92% of subjects with only one severe assessment.

Phase 3 Clinical Trials

Kaken recently completed its pivotal Phase 3 clinical trial in subjects with primary axillary hyperhidrosis in Japan and achieved statistical significance (p<0.05) for primary and all secondary efficacy endpoints.

Based upon the positive results achieved from three completed Phase 2b clinical trials (two in the U.S. and one in Japan via Kaken), Kaken’s pivotal Phase 3 clinical trial, as well as Brickell’s ongoing fully-enrolled Phase 3 long-term safety study in 300 subjects with primary axillary hyperhidrosis in the U.S., Brickell intends to initiate two pivotal Phase 3 clinical trials in approximately 450 subjects per study with primary axillary hyperhidrosis in the U.S. in the fourth quarter of 2019 which are expected to suppport an NDA submission with the FDA. Brickell expects to obtain results from the pivotal Phase 3 clinical trials in the fourth quarter of 2020.

BBI-3000 for the Oral Treatment of CutaneousT-Cell Lymphoma (CTCL)

BBI-3000 was designed as a highly selective and safer (compared to Targretin^®) RXR retinoid agonist currently under development for retinoid responsive skin conditions. While Brickell believes there are several skin indications for which a novel RXR retinoid agonist, such asBBI-3000, may have therapeutic effect (e.g., psoriasis, photo-aging and CTCL), Brickell is currently focused on the development ofBBI-3000 as a potentially better tolerated retinoid for the oral treatment of CTCL.

Retinoids are derivatives of vitamin A that play a pivotal role in a diverse group of biologic processes including, but not limited to, cellular proliferation, differentiation, apoptosis, and development. The biological activity and tolerability of the retinoid depends in part on the binding availability to RAR and RXR receptors. There are several topical retinoids and oral retinoids currently on the market that have shown efficacy in the treatment of several skin conditions, such as CTLC (e.g. bexarotene/Targretin^®) and acne and psoriasis (e.g., tazarotene, adapalene and tretinoin). A common adverse reaction with the use of bexarotene is hyperlipidemia, resulting in abnormally elevated levels of lipids in the blood. Based on current data, Brickell does not expect thatBBI-3000 will cause hyperlipidemia. Considering thatBBI-3000 is anRXR-RXR agonist with no RAR activity,BBI-3000 may provide improvements to the treatment of CTCL by decreasing the incidence of systemic side effects while retaining the efficacy associated with systemic retinoid use. Brickell believes that new oral retinoid treatments, such asBBI-3000, with potentially improved tolerability, and efficacy comparable to Targretin^®, would be welcome in the marketplace.

Clinical Development ofBBI-3000

BBI-3000 is being tested by the National Cancer Institute (NCI) in a Phase 1 clinical study as a chronic, orally administered chemoprevention agent for breast cancer. The product has been well tolerated in the NCI investigations conducted to date (two Phase 1 studies), providing an encouraging signal of the potential overall favorable systemic safety profile ofBBI-3000. Brickell is targeting the initiation of aproof-of-concept clinical study withBBI-3000 for CTCL in late 2020.

BBI-6000 for the Topical Treatment of Psoriasis

BBI-6000 is a novel small molecule retinoic acid-related orphan nuclear receptor gamma (RORg) inhibitor Brickell is developing as a potential prescription topical treatment for psoriasis. Brickell believes that RORg inhibitors possess the potential to inhibit Th17 cell differentiation and reduceIL-17 production.BBI-6000 has been shown to exhibit specific effects on Th17-cell differentiation and has demonstrated selectivity for RORg. Additionally, studies with mouse Th17 cells have demonstrated that the compound suppressesIL-17A with no effect on interferon and in preclinical pharmacology screening,BBI-6000 specifically exhibited strong inhibition ofIL-17A expression. Given the role ofBBI-6000 and RORg onIL-17 cytokine production, Brickell believesBBI-6000 to have potential against a wide range of autoimmune diseases, such as psoriasis.

137.

Preclinical Development

BBI-6000 is currently in the preclinical stages of development, with drug substance manufacturing, preclinical pharmacology testing andpre-formulation studies having been completed to date. Upon completion of the requiredIND-enabling studies, Brickell intends to commence aproof-of-concept clinical trial in patients withmild-to-moderate psoriasis in early 2021.

Rest of Industry

Brickell’s industry is highly competitive and subject to rapid and significant change. While Brickell believes that Brickell’s team’s extensive development and commercialization pharmaceutical experience in launching blockbuster drugs across multiple therapeutic areas, scientific knowledge, and global industry relationships provide Brickell with competitive advantages, Brickell faces competition from pharmaceutical and biotechnology companies, including specialty pharmaceutical companies, as well as generic drug companies,over-the-counter companies, academic institutions, government agencies and research institutions.

Many of Brickell’s competitors have significantly greater financial, technical and human resources than does Brickell. Mergers and acquisitions in the pharmaceutical and biotechnology industries may result in even more resources being concentrated amongst a smaller number of Brickell’s competitors. Brickell’s commercial opportunity could be reduced or eliminated if its competitors develop or market products or other novel therapies that are more effective, safer or less costly than Brickell’s current or future product candidates or obtain regulatory approval for their products more rapidly than Brickell may obtain approval for Brickell’s product candidates. Brickell’s success will be based in part on Brickell’s ability to identify, develop and manage a patented portfolio of product candidates that are safer and more effective than competing products and which will transform patient lives suffering from debilitating skin orders that are chronic and do not go away even with conventional treatment options.

Hyperhidrosis

If approved for the treatment of primary axillary hyperhidrosis, Brickell anticipate that sofpironium bromide would compete with other therapies used for hyperhidrosis, including:

•

Self-Administered Treatments. Self-administered treatments, such as OTC and prescription topical antiperspirants, and Qbrexza (glycopyrronium) 2.4% topical cloths. Oral and compounded topical anticholinergics may also be usedoff-label.

•

Non-Surgical Office-Based Procedures. Office-based procedures have been approved for the treatment of hyperhidrosis, including intradermal injections of BOTOX^®, marketed by Allergan plc., and MiraDry^®, a microwave-based treatment marketed by Miramar Labs, Inc.

•

In addition to approved hyperhidrosis treatments, there are also several treatments under development that could potentially be used to treat hyperhidrosis and may compete with sofpironium bromide.

Intellectual Property andIn-Licensing Agreements

Brickell’s success depends in large part upon Brickell’s ability to obtain and maintain proprietary protection for Brickell’s products and technologies, and to operate without infringing the proprietary rights of others. Brickell seeks to avoid the latter by monitoring patents and publications that may affect Brickell’s business, and to the extent Brickell identifies such developments, evaluate and take appropriate courses of action. With respect to the former, Brickell’s policy is to protect Brickell’s proprietary position by, among other methods, filing for patent applications on inventions that are important to the development and conduct of Brickell’s business with the U.S. Patent and Trademark Office and its foreign counterparts.

138.

Patents extend for varying periods according to the date of patent filing or grant and the legal term of patents in various countries where patent protection is obtained. The actual protection afforded by a patent, which can vary from country to country, depends on the type of patent, the scope of its coverage and the availability of legal remedies in the country.

Brickell also intends to use regulatory exclusivity (also called data package exclusivity) as a means of acquiring intellectual property protections that are separate and distinct to patents. This kind of right involves being given exclusivity for varying periods of time depending on the country to incentivize innovators who invest in clinical trials to produce data to demonstrate a drug is safe and effective and, as such, the data package in an NDA for the FDA should receive protection even if no patent is available. Other countries to varying extents do the same.

Brickell further protects its proprietary information by requiring Brickell’s employees, consultants, contractors and other advisors to execute nondisclosure and assignment of invention agreements upon commencement of their respective employment or engagement. Agreements with Brickell’s employees also prevent them from bringing the proprietary rights of third parties to Brickell. In addition, Brickell requires confidentiality or service agreements from third parties that receive Brickell’s confidential information or materials.

As of June 30, 2019, Brickell owns or possesses an exclusive license to 23 issued U.S. patents and 43 issued foreign patents, which include granted European patent rights that have been validated in various EU member states, and nine pending U.S. patent applications and 94 pending foreign patent applications. U.S. and foreign patents and pending U.S. and foreign patent applications for sofpironium bromide, if issued, will expire between 2031 and 2039, taking potential patent term extension into consideration.

Sofpironium bromide is covered by issued patents (composition of matter and methods of use and dosing thereof) in the United States with expected coverage through 2031 (including potential patent term extension which Brickell anticipates adding 4 to 5 years of patent exclusivity) and 2034, with potential additional U.S. and global coverage through 2034 and 2039 (formulations, methods, devices and manufacturing). Brickell also filed a new composition of matter patent application in the United States that would provide expected coverage through 2040, if approved.

Brickell also uses other forms of protection besides regulatory exclusivity, such as trademark, copyright, and trade secret protection, to enhance its intellectual property, particularly where Brickell does not believe patent protection is appropriate or obtainable. Brickell aims to take advantage of all of the intellectual property rights that are available to Brickell and believe that this comprehensive approach will provide Brickell with proprietary exclusive positions for Brickell’s product candidates, where available.

In-License Agreements

Sofpironium Bromide

Brickell executed a license agreement in December 2012 with Bodor Laboratories, Inc. (“Bodor”) for a worldwide, exclusive license to develop, manufacture, market, sell and sublicense technology products containing the compound based upon the patents referenced, with a field of use, limited to the treatment of hyperhidrosis and excessive sweating. In exchange for such rights, Brickell agreed to pay Bodor: (i) an upfront payment upon execution of the license; (ii) half of all royalties received from covered sales in Asia; (iii) a low tomid-single digit royalty on all covered sales of products anywhere outside of Asia by us; (iv) a low tomid-single digit royalty on all sales of products bysub-licensees, plus a percentage in the event suchsub-licensee patent royalty rate exceeds a certain threshold percentage; (v) additional regulatory and sales milestone payments commencing at the completion of a Phase 2 study; and (vi) certain sublicensing fees. In addition, the license agreement imposes various diligence, milestone, royalty, insurance and other obligations on Brickell. If Brickell fails to comply with these obligations, Bodor may have the right to terminate the license, in which event Brickell may not be able to develop or market sofpironium bromide.

139.

BBI-3000

In June 2012, Brickell executed a license agreement with the UAB Research Foundation (“UABRF”) for a worldwide, exclusive license to manufacture, market, sell and sublicense technology products containing the compound based upon the patents referenced with a field of use limited to all dermatological indications. In exchange for such rights, Brickell agreed to pay UABRF: (i) an upfront payment upon the execution of the license agreement; (ii) a low tomid-single digit royalty on all sales of products anywhere in the world by Brickell and itssub-licensees; (iii) additional regulatory and sales milestone payments commencing at the successful completion of a Phase 2 study; and (iv) certain sublicensing fees. In addition, Brickell will be responsible for the payment of future expenses for filing, prosecuting and maintaining licensed technologies and for any new patents that Brickell intends to file, prosecute and maintain. The license agreement also imposes various diligence, milestone, royalty, insurance and other obligations on Brickell. If Brickell fails to comply with these obligations, UABRF may have the right to terminate the license, in which event Brickell may not be able to develop or marketBBI-3000.

BBI-6000

In November 2015, Brickell executed an asset purchase agreement with Orca Pharmaceuticals LLC (“Orca”) to acquire certain compounds, assigned technology, inventory and patent files associated withBBI-6000. One of the assets purchased from Orca was a license agreement between Orca and New York University (“NYU”) which granted Orca an exclusive license to manufacture, market, sell and sublicense technology products based upon certain specified patents. In exchange for such rights, Brickell agreed to pay Orca: (i) an upfront payment upon execution of the agreement; (ii) a low tomid-single digit royalty on net sales of products anywhere in the world by Brickell and itssub-licensees; and (iii) additional regulatory and sales milestone payments. In addition, the asset purchase agreement imposes various diligence, milestone, royalty, insurance and other obligations on Brickell. If Brickell fails to comply with these obligations, Orca may have the right to terminate the agreement, in which event Brickell may not be able to develop or marketBBI-6000.

Early-Stage Research Programs

Brickell also owns early-stage research programs targeting other skin diseases, such as androgenic alopecia and contact dermatitis, that were acquired through asset purchase or license agreements in exchange for (i) upfront payments upon execution of the license; (ii) low tomid-single to high-single digit royalties on product sales; (iii) regulatory and sales milestone payments; and (iv) certain sublicensing fees.

Government Regulation

FDA Drug Approval Process

In the United States, pharmaceutical products are subject to extensive regulation by the FDA. The Federal Food, Drug, and Cosmetic Act (the “FDC Act”) and other federal and state statutes and regulations, govern,

140.

among other things, the research, development, testing, manufacture, storage, recordkeeping, approval, labeling, advertising, promotion and marketing, distribution, post-approval monitoring and reporting, sampling and import and export of pharmaceutical products. Failure to comply with applicable U.S. requirements may subject a company to a variety of administrative or judicial sanctions, such as FDA refusal to approve pending NDAs, warning or untitled letters, product recalls, product seizures, total or partial suspension of production or distribution, injunctions, fines, civil penalties, corporate integrity agreements, and criminal prosecution.

Pharmaceutical product development for a new product or certain changes to an approved product in the United States typically involves preclinical laboratory and animal tests, the submission to the FDA of an IND, which must become effective before clinical testing may commence, and adequate and well-controlled clinical trials to establish the safety and effectiveness of the drug for each indication for which FDA approval is sought. In addition, other tests on the chemistry, manufacturing and controls (CMC) of producing the drug and its various formulations to establish the shelf life, storage conditions and quality parameters and specification must be conducted and submitted.

Satisfaction of FDApre-market approval requirements typically takes many years and the actual time required may vary substantially based upon the type, complexity and novelty of the product or disease. Preclinical tests include laboratory evaluation of product chemistry, formulation and toxicity, as well as animal trials to assess the characteristics and potential safety and efficacy of the product. The conduct of the preclinical tests must comply with federal regulations and requirements, including good laboratory practices. The results of preclinical testing are submitted to the FDA as part of an IND along with other information, including information about product chemistry, manufacturing and controls described above and a proposed clinical trial protocol. Long-term preclinical tests, such as animal tests of reproductive toxicity and carcinogenicity, may continue after the IND is submitted.

A30-day waiting period after the submission of each IND is required prior to the commencement of clinical testing in humans. If the FDA has neither commented on nor questioned the IND within this30-day period, the clinical trial proposed in the IND may begin.

Clinical trials involve the administration of the investigational new drug to healthy volunteers or patients under the supervision of a qualified physician investigator. Clinical trials must be conducted (1) in compliance with federal and state regulations; (2) in compliance with good clinical practice (“GCP”), an international standard meant to protect the rights and health of patients and to define the roles of clinical trial sponsors, administrators and monitors; and (3) under protocols detailing the objectives of the trial, the parameters to be used in monitoring safety and the effectiveness criteria to be evaluated as well as the actual primary and secondary endpoints of the study to be evaluated. Each protocol involving testing on U.S. patients and subsequent protocol amendments must be submitted to the FDA as part of the IND.

The FDA may order the temporary, or permanent, discontinuation of a clinical trial at any time, or impose other sanctions, if it believes that the clinical trial either is not being conducted in accordance with FDA requirements or presents an unacceptable risk to the clinical trial patients. The study protocol and informed consent information for patients in clinical trials must also be submitted to a local or central institutional review board (“IRB”) (outside the U.S. these are called Ethics Committees) for approval at each site at which the clinical trial will be conducted. An IRB may also require the clinical trial at the site to be halted, either temporarily or permanently, for failure to comply with the IRB’s requirements, or may impose other conditions.

Clinical trials to support NDAs for marketing approval are typically conducted in three sequential phases, but the phases may overlap, or in rarer cases early phases may be skipped depending on the amount and quality of data that exists. In Phase 1, the initial introduction of the drug into healthy human subjects or patients, the drug is tested to assess pharmacological actions, side effects associated with increasing doses and, if possible, early evidence on effectiveness. For dermatology products, Phase 2 usually involves trials in a limited patient population to determine metabolism, pharmacokinetics, the effectiveness of the drug for a particular indication,

141.

dosage tolerance and optimum dosage, and to identify common adverse effects and safety risks. If a compound demonstrates evidence of effectiveness and an acceptable safety profile in Phase 2 evaluations, Phase 3 clinical trials are undertaken to obtain the additional information about clinical efficacy and safety in a larger number of patients, typically at geographically dispersed clinical trial sites, to permit the FDA to evaluate the overall benefit-risk relationship of the drug and to provide adequate information for the labeling of the drug. In most cases the FDA requires two adequate and well-controlled prospective Phase 3 clinical trials with statistically significant results to demonstrate the efficacy of the drug by comparing a treatment arm against a control (placebo or best supportive care) arm. A single Phase 3 clinical trial with other confirmatory evidence may be sufficient in rare instances for FDA registration where the study is a large multicenter trial demonstrating internal consistency and a statistically very persuasive finding of an effect on mortality, irreversible morbidity or prevention of a disease with a potentially serious outcome and confirmation of the result in a second trial would be practically impossible or ethically problematic.

After completion of the required clinical testing, a new drug application (“NDA”) is prepared and submitted to the FDA. FDA approval of the NDA is required before marketing of the product may begin in the United States, although there are programs during this stage that allow the investigational drug to be used in a compassionate care orright-to-try setting when certain facts are present. The NDA must include the results of all preclinical, clinical and other testing and a compilation of data relating to the product’s pharmacology, chemistry, manufacture and controls. The cost of preparing and submitting an NDA is substantial. The submission of most NDAs is additionally subject to a substantial application user fee, and the manufacturer and sponsor under an approved new drug application are also subject to annual product and establishment user fees. These fees are typically increased annually.

The FDA has 60 days from its receipt of an NDA to determine whether the application will be accepted for filing based on the agency’s threshold determination that it is sufficiently complete to permit substantive review. Once the submission is accepted for filing, the FDA begins anin-depth review. The FDA has agreed with Congress to certain performance goals in the review of new drug applications. Priority review or similar accelerated pathways can be applied to drugs that the FDA determines offer major advances in treatment, or provide a treatment where no adequate or satisfactory, comparable therapy exists. For biologics, priority review is further limited only for drugs intended to treat a serious or life-threatening disease relative to the currently approved products. The review process for both standard and priority review may be extended by the FDA for three additional months to consider certain late-submitted information, or information intended to clarify information already provided in the submission.

The FDA may also refer applications for novel drug products, or drug products that present difficult questions of safety or efficacy, to an advisory committee, typically a panel that includes independent clinicians and other experts in the targeted disease, for review, evaluation and a recommendation as to whether the application should be approved. The FDA is not bound by the recommendation of an advisory committee, but it generally follows such recommendations. Before approving an NDA, the FDA will typically inspect one or more of the sponsor’s clinical sites to assure compliance with GCP. Additionally, the FDA will inspect the facility or the facilities at which the drug is manufactured. The FDA will not approve the product unless compliance with current good manufacturing practice (“cGMP”) is satisfactory and the NDA contains data that provide substantial evidence that the drug is safe and effective in the indication studied.

After the FDA evaluates the NDA and the manufacturing facilities, it issues either an approval letter or a complete response letter. A complete response letter generally outlines the deficiencies in the submission and may require substantial additional testing, or information, in order for the FDA to reconsider the application. If, or when, those deficiencies have been addressed to the FDA’s satisfaction in a resubmission of the NDA, the FDA will issue an approval letter. The FDA has committed to reviewing such resubmissions in two or six months depending on the type of information required.

An approval letter authorizes commercial marketing of the drug with specific prescribing information for specific indications. The approval letter may contain safety information that limits the ability of the drug to be

142.

marketed (e.g., black box warning) or contains contraindications, warnings and/or precautions that limit the potential of the drug’s desirability. As another potential condition of NDA approval, the FDA may require a risk evaluation and mitigation strategy (“REMS”) to help ensure that the benefits of the drug outweigh the potential risks. REMS can include medication guides, communication plans for healthcare professionals and elements to assure safe use (“ETASU”). ETASU can include, but are not limited to, special training or certification for prescribing or dispensing, dispensing only under certain circumstances, special monitoring and the use of patient registries. The requirement for a REMS can materially affect the potential market and profitability of the drug. Moreover, product approval may require substantial post-approval testing and surveillance to monitor the drug’s safety or efficacy. Once granted, product approvals may be withdrawn if compliance with regulatory standards is not maintained or problems are identified following initial marketing and/or manufacturing.

Changes to some of the conditions established in an approved application, including changes in indications, labeling, or manufacturing processes or facilities, require submission and FDA approval of a new NDA or NDA supplement before the change can be implemented. An NDA supplement for a new indication typically requires clinical data similar to that in the original application, and the FDA uses the same procedures and actions in reviewing NDA supplements as it does in reviewing NDAs.

The Hatch-Waxman Act

In seeking approval for a drug through an NDA, applicants are required to list with the FDA each patent whose claims cover the applicant’s product. Upon approval of a drug, each of the patents listed in the application for the drug is then published in the FDA’s Approved Drug Products with Therapeutic Equivalence Evaluations, commonly known as the Orange Book. Drugs listed in the Orange Book can, in turn, be cited by potential generic competitors in support of approval of an abbreviated new drug application (“ANDA”). An ANDA provides for marketing of a drug product that has the same active ingredients in the same strengths and dosage form as the listed drug and has been shown through bioequivalence testing to be therapeutically equivalent to the listed drug. Other than the requirement for bioequivalence testing, ANDA applicants are not required to conduct, or submit results of, preclinical or clinical tests to prove the safety or effectiveness of their drug product. Drugs approved in this way are commonly referred to as “generic equivalents” to the listed drug, and can often be substituted by pharmacists under prescriptions written for the original listed drug and may be required to be switched to from the original innovator drug by certain laws or insurance and formulary practices, which can affect the profitability of the drug adversely.

The ANDA applicant is required to certify to the FDA concerning any patents listed for the approved product in the FDA’s Orange Book. Specifically, the applicant must certify that (1) the required patent information has not been filed; (2) the listed patent has expired; (3) the listed patent has not expired, but will expire on a particular date and approval is sought after patent expiration; or (4) the listed patent is invalid or will not be infringed by the new product. The ANDA applicant may also elect to submit a section viii statement certifying that its proposed ANDA label does not contain (or carves out) any language regarding the patentedmethod-of-use rather than certify to a listedmethod-of-use patent. If the applicant does not challenge the listed patents, the ANDA will not be approved until all the listed patents claiming the referenced product have expired.

A certification that the new product will not infringe the already approved product’s listed patents, or that such patents are invalid, is called a Paragraph IV certification. If the ANDA applicant has provided a Paragraph IV certification to the FDA, the applicant must also send notice of the Paragraph IV certification to the NDA and patent holders once the ANDA has been accepted for filing by the FDA. The NDA and patent holders may then commence a patent infringement lawsuit in response to the notice of the Paragraph IV certification. The filing of a patent infringement lawsuit within 45 days of the receipt of a Paragraph IV certification automatically prevents the FDA from approving the ANDA until the earlier of 30 months, expiration of the patent, settlement of the lawsuit, or a decision in the infringement case that is favorable to the ANDA applicant.

The ANDA also will not be approved until any applicablenon-patent exclusivity listed in the Orange Book for the referenced product has expired.

143.

Regulatory Exclusivity

Upon NDA approval of a new chemical entity or NCE, which is a drug that contains no active molecule that has been approved by the FDA in any other NDA, that drug receives five years of marketing exclusivity during which the FDA cannot receive any ANDA seeking approval of a generic version of that drug. Certain changes to a drug, such as the addition of a new indication to the package insert, are associated with a three-year period of exclusivity during which the FDA cannot approve an ANDA for a generic drug that includes the change.

An ANDA may be submitted one year before NCE exclusivity expires if a Paragraph IV certification is filed. If there is no listed patent in the Orange Book, there may not be a Paragraph IV certification and, thus, no ANDA may be filed before the expiration of the exclusivity period.

Section 505(b)(2) New Drug Applications

Most drug products obtain FDA marketing approval pursuant to an NDA or an ANDA. A third alternative is a special type of NDA, commonly referred to as a Section 505(b)(2), or 505(b)(2), NDA, which enables the applicant to rely, in part, on the FDA’s previous approval of a similar product, or published literature, in support of its application.

505(b)(2) NDAs often provide an alternate path to FDA approval for new or improved formulations or new uses of previously approved products. Section 505(b)(2) permits the filing of an NDA where at least some of the information required for approval comes from studies not conducted by, or for, the applicant and for which the applicant has not obtained a right of reference. If the 505(b)(2) applicant can establish that reliance on the FDA’s previous approval is scientifically appropriate, it may eliminate the need to conduct certain preclinical or clinical studies of the new product. The FDA may also require companies to perform additional studies or measurements to support the change from the approved product. The FDA may then approve the new product candidate for all, or some, of the label indications for which the referenced product has been approved, as well as for any new indication sought by the Section 505(b)(2) applicant.

To the extent that the Section 505(b)(2) applicant is relying on studies conducted for an already approved product, the applicant is required to certify to the FDA concerning any patents listed for the approved product in the Orange Book to the same extent that an ANDA applicant would. Thus approval of a 505(b)(2) NDA can be stalled until all the listed patents claiming the referenced product have expired, until anynon-patent exclusivity, such as exclusivity for obtaining approval of a new chemical entity, listed in the Orange Book for the referenced product has expired, and, in the case of a Paragraph IV certification and subsequent patent infringement suit, until the earlier of 30 months, settlement of the lawsuit or a decision in the infringement case that is favorable to the Section 505(b)(2) applicant.

Patent Term Extension

After NDA approval, owners of relevant drug patents may apply for up to a five-year patent extension. The allowable patent term extension is calculated as half of the drug’s testing phase, the time between IND application and NDA submission, and all of the review phase, the time between NDA submission and approval, up to a maximum of five years. The time can be shortened if the FDA determines that the applicant did not pursue approval with due diligence. The total patent term after the extension may not exceed 14 years.

For patents that might expire during the application phase, the patent owner may request an interim patent extension. An interim patent extension increases the patent term by one year and may be renewed up to Brickell’s times. For each interim patent extension granted, the post-approval patent extension is reduced by one year. The director of the USPTO must determine that approval of the drug covered by the patent for which a patent extension is being sought is likely. Interim patent extensions are not available for a drug for which an NDA has not been submitted.

144.

Post-Approval Requirements

Once an NDA is approved, a product will be subject to certain post-approval requirements. For instance, the FDA closely regulates, in part, the post-approval marketing and promotion of drugs, including standards and regulations fordirect-to-consumer advertising,off-label promotion, formulary and reimbursement presentations, product sampling, sales force activities including dissemination of peer-reviewed journal articles and detailing practices with prescribers, health care practitioner interactions, industry-sponsored scientific and educational activities and promotional activities involving the internet while other parts of the government regulate against false claims, foreign corrupt practices, trade sanctions, and anti-kickbacks. States often impose strict legal requirements and prohibitions on a variety of post-approval drug marketing practices. Drugs may be marketed by the sponsor only for the approved indications and in accordance with the provisions of the approved labeling.

Adverse event reporting, pharmacovigilance and submission of periodic reports is required following FDA approval of an NDA. The FDA also may require post-marketing testing, known as Phase 4 testing, the aforementioned REMS and surveillance to monitor the effects of an approved product, or the FDA may place conditions on an approval that could restrict the distribution or use of the product. In addition, quality-control, drug manufacture, packaging and labeling procedures must continue to conform to cGMPs after approval. Drug manufacturers and certain of their subcontractors are required to register their establishments with the FDA and certain state agencies. Registration with the FDA subjects entities to periodic unannounced inspections by the FDA, during which the agency inspects manufacturing facilities to assess compliance with cGMPs. Accordingly, manufacturers must continue to expend time, money and effort in the areas of production and quality-control to maintain compliance with cGMPs or risk being sanctioned by FDA from supplying the drugs they manufacture. Regulatory authorities also may withdraw product approvals or request product recalls if a company fails to comply with regulatory standards, if it encounters problems following initial marketing and supply, or if previously unrecognized problems are subsequently discovered.

Pediatric Information

Under the Pediatric Research Equity Act, NDAs or supplements to NDAs must contain data to assess the safety and effectiveness of the drug for the claimed indications in all relevant pediatric subpopulations and to support dosing and administration for each pediatric subpopulation for which the drug is safe and effective. The FDA may grant full or partial waivers, or deferrals, for submission of data.

The Best Pharmaceuticals for Children Act (“BPCA”) provides NDA holders asix-month extension of any exclusivity, patent ornon-patent, for a drug if certain conditions are met. Conditions for exclusivity include the FDA’s determination that information relating to the use of a new drug in the pediatric population may produce health benefits in that population, the FDA making a written request for pediatric studies and the applicant agreeing to perform, and report on, the requested studies within the statutory timeframe. Applications under the BPCA are treated as priority applications, with all of the benefits that designation confers.

Disclosure of Clinical Trial Information

Sponsors of clinical trials ofFDA-regulated products, including drugs, are required to register and disclose certain clinical trial information, including when a clinical trial is initiated (often on www.clintrials.gov). Information related to the product, patient population, phase, type and scope of investigation, study sites and investigators and other aspects of the clinical trial is then made public as part of the registration process. Sponsors are also obligated to discuss the results of their clinical trials after completion and industry trade association ethics guidelines require publication of both favorable and unfavorable study results, which can affect the potential for a drug. Disclosure of the results of these trials can be delayed until the new product or new indication being studied has been approved. Competitors may use this publicly available information to gain knowledge regarding the progress of development programs.

145.

Regulation Outside of the United States

In addition to regulations in the United States, Brickell will be subject to regulations of other countries governing any clinical trials and commercial sales and distribution of Brickell’s product candidates, as well as extent, scope and enforceability of intellectual property rights associated with the product candidate. Whether or not Brickell obtains FDA approval for a product, Brickell must obtain approval by the comparable regulatory authorities of countries outside of the United States before it can commence clinical trials in such countries and approval of the regulators of such countries or economic areas, such as the European Union, before Brickell may market products in those countries or areas. Certain countries outside of the United States have a process similar to the FDA’s that requires the submission of a clinical trial application (“CTA”), much like the IND prior to the commencement of human clinical trials. In the European Union, for example, a CTA must be submitted to each country’s national health authority and an independent ethics committee, much like the FDA and IRB, respectively. Once the CTA is approved in accordance with a country’s requirements, clinical trial development may proceed. The approval process and requirements governing the conduct of clinical trials, product licensing, pricing and reimbursement vary greatly from place to place, and the time may be longer or shorter than that required for FDA approval. In some cases, once the investigational drug is approved by a regulatory agency in certain established markets, like the FDA in the U.S., other countries will allow a sponsor to rely on that other country’s approval and extend it, with the same terms and conditions, in the foreign country and this can greatly accelerate the introduction of the drug in foreign markets, where applicable (often called a free sales certificate (“FSC”) process).

Under European Union regulatory systems, a company may submit marketing authorization applications either under a centralized or decentralized procedure. The centralized procedure, which is compulsory for medicines produced by biotechnology or those medicines intended to treat AIDS, cancer, neurodegenerative disorders or diabetes and is optional for those medicines which are highly innovative, provides for the grant of a single marketing authorization that is valid for all European Union member states. The decentralized procedure provides for mutual recognition of national approval decisions. Under this procedure, the holder of a national marketing authorization may submit an application to the remaining member states. Within 90 days of receiving the applications and assessments report, each member state must decide whether to recognize approval. If a member state does not recognize the marketing authorization, the disputed points are eventually referred to the European Commission, whose decision is binding on all member states.

Anti-Kickback, False Claims Laws

In addition to FDA restrictions on marketing of pharmaceutical products, several other types of state and federal laws have been applied to restrict or prohibit certain marketing practices in the pharmaceutical industry. These laws include, among others, anti-kickback statutes, false claims statutes and other statutes pertaining to healthcare fraud and abuse, and anticorruption. The federal healthcare program anti-kickback statute prohibits, among other things, knowingly and willfully offering, paying, soliciting or receiving remuneration to induce, or in return for, purchasing, leasing, ordering or arranging for the purchase, lease or order of any healthcare item or service reimbursable under Medicare, Medicaid or other federally financed healthcare programs. The Patient Protection and Affordable Care Act, as amended (“PPACA”), amended the intent element of the federal anti-kickback statute so that a person or entity no longer needs to have actual knowledge of the statute or specific intent to violate it. This statute has been interpreted to apply to arrangements between pharmaceutical manufacturers on the one hand and prescribers, purchasers and formulary managers on the other. Although there are a number of statutory exceptions and regulatory safe harbors protecting certain common activities from prosecution or other regulatory sanctions, the exceptions and safe harbors are drawn narrowly, and practices that involve remuneration intended to induce prescribing, purchases or recommendations may be subject to scrutiny if they do not qualify for an exception or safe harbor.

Federal false claims laws prohibit any person or entity from, among other things, knowingly presenting, or causing to be presented, a false claim for payment to the federal government, or knowingly making, or causing to

146.

be made, a false statement to have a false claim paid. This includes claims made to programs where the federal government reimburses, such as Medicaid, as well as programs where the federal government is a direct purchaser, such as when it purchases off the Federal Supply Schedule. Pharmaceutical and other healthcare companies have been prosecuted under these laws for, among other things, allegedly inflating drug prices they report to pricing services, which in turn were used by the government to set Medicare and Medicaid reimbursement rates, and for allegedly providing free product to customers with the expectation that the customers would bill federal programs for the product. In addition, certain marketing practices, including off-label promotion, may also violate federal false claims laws. Additionally, PPACA amended the federal healthcare program anti-kickback statute such that a violation of that statute can serve as a basis for liability under certain federal false claims laws.

The majority of states also have statutes or regulations similar to the federal anti-kickback law and false claims laws, which apply to items and services reimbursed under Medicaid and other state programs, or, in several states, apply regardless of the payor.

Other federal statutes pertaining to healthcare fraud and abuse include the civil monetary penalties statute, which prohibits, among other things, the offer or payment of remuneration to a Medicaid or Medicare beneficiary that the offeror or payor knows or should know is likely to influence the beneficiary to order or receive a reimbursable item or service from a particular supplier, and the healthcare fraud and false statements statutes, which prohibit, among other things, knowingly and willfully executing or attempting to execute a scheme to defraud any healthcare benefit program or obtain by means of false or fraudulent pretenses, representations, or promises any money or property owned by or under the control of any healthcare benefit program in connection with the delivery of or payment for healthcare benefits, items, or services.

Violations of these federal healthcare fraud and abuse laws are punishable by imprisonment, criminal fines, civil monetary penalties and exclusion from participation in federal healthcare programs.

Other Federal and State Regulatory Requirements

The Centers for Medicare & Medicaid Services (“CMS”) has issued a final rule pursuant to PPACA that requires certain manufacturers of prescription drugs to annually collect and report information on payments or transfers of value to physicians and teaching hospitals, as well as ownership and investment interests held by physicians and their immediate family members. Manufacturers are required to collect information with the reported data posted in searchable form on a public website. Failure to submit required information may result in civil monetary penalties. Other countries require similar reporting, especially in France and Belgium.

Federal law also requires pharmaceutical companies to post public statements, usually via the Internet, on whether they will approve compassionate use requests for their investigational drugs still in the clinic.

In addition, several states now require prescription drug companies to report expenses relating to the marketing and promotion of drug products and to report gifts and payments to individual healthcare practitioners and entities in these states. Other states prohibit various other marketing-related activities. Still other states require the posting of information relating to clinical studies and their outcomes. In addition, California, Connecticut, Nevada and Massachusetts require pharmaceutical companies to implement compliance programs and marketing codes. Several additional states are considering similar proposals. Some of the state laws are broader in scope than federal laws. Compliance with these laws is difficult and time-consuming, and companies that do not comply with these state laws face civil or other penalties.

Reimbursement

Sales of any of Brickell’s product candidates that are approved will depend, in part, on the extent to which the costs of its approved products will be covered and reimbursed by third-party payors, such as government

147.

health programs, commercial insurance and managed healthcare organizations. These third-party payors are increasingly challenging the prices charged for medical products and services and often create drug formularies with onerous requirements for inclusion where inclusion is the only way a drug can be reimbursed. Additionally, the containment of healthcare costs has become a priority of federal and state governments and the prices of drugs have been a focus in this effort. The U.S. government, state legislatures and foreign governments have shown significant interest in implementing cost-containment programs, including price controls, restrictions on reimbursement and requirements for voluntary and sometimes mandatory substitution of generic products. In addition, certain government purchasers of medicines, like CMS under the Medicaid program, impose a best pricing system where the best price that is offered to any U.S. customer must also be given to the federal government. And foreign countries increasingly are adopting reference pricing where the lowest price offered by a drug sponsor in a particular list of countries must be offered in the referencing country. Adoption of price controls and cost-containment measures, and adoption of more restrictive policies in jurisdictions with existing controls and measures, could further limit Brickell’s net revenue and results. If any of the company’s products are approved and these third-party payors do not consider Brickell’s approved products to be cost-effective compared to other therapies, they may not cover Brickell’s approved products as a benefit under their plans or, if they do, the level of payment may not be sufficient to allow Brickell to sell its approved products on a profitable basis.

The Medicare Prescription Drug, Improvement, and Modernization Act of 2003 (“MMA”) imposed new requirements for the distribution and pricing of prescription drugs for Medicare beneficiaries. Under Part D, Medicare beneficiaries may enroll in prescription drug plans offered by private entities which will provide coverage of outpatient prescription drugs. Part D plans include both stand-alone prescription drug benefit plans and prescription drug coverage as a supplement to Medicare Advantage plans. Unlike Medicare Part A and B, Part D coverage is not standardized. Part D prescription drug plan sponsors are not required to pay for all covered Part D drugs, and each drug plan can develop its own drug formulary that identifies which drugs it will cover and at what tier or level. However, Part D prescription drug formularies must include drugs within each therapeutic category and class of covered Part D drugs, though not necessarily all the drugs in each category or class. Any formulary used by a Part D prescription drug plan must be developed and reviewed by a pharmacy and therapeutic committee. Government payment for some of the costs of prescription drugs may increase demand for Brickell’s products for which it receives marketing approval. However, any negotiated prices for Brickell’s approved products covered by a Part D prescription drug plan will likely be lower than the prices Brickell might otherwise obtain. Moreover, while the MMA applies only to drug benefits for Medicare beneficiaries, private payors often follow Medicare coverage policy and payment limitations in setting their own payment rates. Any reduction in payment that results from the MMA may result in a similar reduction in payments from nongovernmental payors.

The ARRA provides funding for the federal government to compare the effectiveness of different treatments for the same illness. A plan for the research will be developed by the Department of Health and Human Services, the Agency for Healthcare Research and Quality and the National Institutes for Health, and periodic reports on the status of the research and related expenditures will be made to the U.S. Congress. Although the results of the comparative effectiveness studies are not intended to mandate coverage policies for public or private payors, it is not clear what effect, if any, the research will have on the sales of any approved product, if any such product or the condition that it is intended to treat is the subject of a study. It is also possible that if comparative effectiveness research demonstrates benefits in a competitor’s product, this could adversely affect the sales of Brickell’s product candidates. If third-party payors do not consider Brickell’s approved products to be cost-effective based on health economics data compared to other available therapies, they may not cover Brickell’s approved products as a benefit under their plans or, if they do, the level of payment may not be sufficient to allow Brickell to sell its approved products on a profitable basis.

In addition, in somenon-U.S. jurisdictions, the proposed pricing for a product candidate must be approved before it may be lawfully marketed. The requirements governing drug pricing vary widely from country to country. For example, the European Union provides options for its member states to restrict the range of

148.

medicinal products for which their national health insurance systems provide reimbursement and to control the prices of medicinal products for human use. A member state may approve a specific price for the medicinal product or it may instead adopt a system of direct or indirect controls on the profitability of the company placing the medicinal product on the market. There can be no assurance that any country that has price controls or reimbursement limitations for pharmaceutical products will allow favorable reimbursement and pricing arrangements for any of Brickell’s product candidates. Historically, product candidates launched in the European Union do not follow price structures of the United States and generally tend to be significantly lower, even lower than pricing that might be obtainable in emerging market countries.

Manufacturing and Supply

Brickell currently contracts with third parties for the manufacture of its small-molecule drug substances and drug products for preclinical studies and clinical trials and intends to continue to do so in the future. To Brickell’s knowledge, all of its clinical drug product manufacturing activities are in compliance with cGMP. Brickell has assembled a team of experienced employees and consultants to provide the necessary technical, quality and regulatory oversight over the contract manufacturing organizations (“CMOs”) with which Brickell contracts. Brickell relies on third-party cGMP manufacturers forscale-up and process development work and to produce sufficient quantities of development product candidates for use in clinical and preclinical trials.

Employees

As of June 30, 2019, Brickell had 11 regular full-time employees, including seven in research and development. From time to time, Brickell retain independent contractors. None of Brickell’s employees is represented by a labor union or covered by a collective bargaining agreement. Brickell have not experienced any work stoppages, and Brickell consider Brickell’s relations with Brickell’s employees to be excellent.

Facilities

Brickell’s corporate headquarters are currently, and following the Merger, will continue to be located in Boulder, Colorado, where it occupies facilities totaling approximately 3,038 square feet under lease agreements that expire in October 2021. Brickell uses its current facilities for research and development and general and administrative personnel. Brickell may seek to expand its current facilities or place certain operations in other states in the next 12 to 18 months.

Legal Proceedings

From time to time, Brickell may become involved in legal proceedings arising in the ordinary course of its business. Brickell is not presently a party to any legal proceedings that, if determined adversely to it, would individually or taken together have a material adverse effect on Brickell.

MANAGEMENT’S DISCUSSION AND ANALYSIS OF BRICKELL’S FINANCIAL CONDITION

AND RESULTS OF OPERATIONS

The following discussion and analysis of Brickell’s financial condition and results of operations should be read together with its financial statements and the other financial information appearing elsewhere in this proxy statement. This discussion contains forward-looking statements that involve risks and uncertainties. Brickell’s actual results could differ materially from those anticipated in the forward-looking statements as a result of various factors, including those discussed below and those discussed in the section titled “Risk Factors” included elsewhere in this proxy statement.

Overview

Brickell is a clinical-stage pharmaceutical company focused on developing innovative and differentiated prescription therapeutics for the treatment of debilitating skin diseases. Brickell’s pipeline consists of potential novel therapeutics for hyperhidrosis, cutaneousT-cell lymphoma, psoriasis, and other prevalent dermatological conditions. Brickell believes that its portfolio of product candidates targets significant market opportunities where innovative therapies are needed. Brickell’s pivotal Phase3-ready clinical-stage product candidate, sofpironium bromide, is a new molecular entity and “soft” drug that belongs to a class of medications called anticholinergics. Brickell is developing sofpironium bromide as a potentialbest-in-class, self-administered, once-daily, topical prescription hyperhidrosis therapy for the treatment of primary axillary hyperhidrosis. Brickell intends to maximize the value of its pipeline assets via continued development activities or partnership opportunities.

Brickell’s operations to date have been limited to business planning, raising capital, developing Brickell’s pipeline assets (in particular sofpironium bromide), identifying product candidates, and other research and development. To date, Brickell has financed operations primarily through private placements of convertible preferred stock, debt and funds received from license and collaboration agreements. Brickell does not have any products approved for sale and has not generated any product sales. Since inception and through June 30, 2019, Brickell has raised an aggregate of $85.9 million to fund operations, of which $39.1 million was through license and collaboration agreements, $33.6 million was from the sale of convertible preferred stock, $7.5 million was from the sale of debt, and $5.1 million was from the sale of convertible notes. As of June 30, 2019, Brickell had cash and cash equivalents totaling $2.1 million.

Since inception, Brickell has incurred operating losses. Brickell recorded a net loss of $8.2 million and $3.0 million for the six months ended June 30, 2019 and 2018, respectively. Brickell incurred a net loss of $9.2 million and $11.1 million for the years ended December 31, 2018 and 2017, respectively. As of June 30, 2019, Brickell had an accumulated deficit of $69.3 million. Brickell expects to continue incurring significant expenses and operating losses for at least the next several years as it:

•

initiates and completes its two pivotal Phase 3 clinical trial for sofpironium bromide;

•

contracts to manufacture product candidates;

•

advances research and development related activities to develop and expand the product pipeline;

•

maintains, expands and protects the intellectual property portfolio;

•

hires additional staff, including clinical, scientific, and management personnel; and

•

adds operational and finance personnel to support product development efforts and, if the Merger is approved, to support operating a public company.

Brickell does not expect to generate significant revenue unless and until it successfully completes development of, obtains marketing approval for and commercializes product candidates, either alone or in

151.

collaboration with third parties. Brickell expects these activities will take several years and its success in these efforts is subject to significant uncertainty. Accordingly, Brickell expects it will need to raise additional capital prior to the regulatory approval and commercialization of any of its product candidates. Until such time, if ever, that Brickell generates substantial product revenues, Brickell expects to finance its operations through public or private equity or debt financings, collaborations or licenses or other available financing transactions. However, Brickell may be unable to raise additional funds through these or other means when needed.

Merger Agreement

On June 2, 2019, Brickell, Merger Sub, and Vical, entered into the Merger Agreement, pursuant to which, among other matters, and subject to the satisfaction or waiver of the conditions set forth in the Merger Agreement, Merger Sub will merge with and into Brickell, with Brickell continuing as a wholly-owned subsidiary of Vical and the surviving corporation of the Merger.

Subject to the terms and conditions of the Merger Agreement, at the effective time of the Merger, each outstanding share of Brickell‘s preferred stock and common stock, along with outstanding convertible notes, will be converted into shares of Vical common stock. Applying the Exchange Ratio, the former Brickell securityholders and NovaQuest, collectively, are expected to own, subject to adjustment, approximately 60% of the aggregate number of shares of Vical common stock, and the securityholders of Vical as of immediately prior to the Merger are expected to own, subject to adjustment, approximately 40% of the aggregate number of shares of Vical common stock (in each case on a fully diluted basis using the treasury stock method in instances other than with respect to the NovaQuest Warrants and certain equity issuances by Brickell following the signing of the Merger Agreement and prior to the completion of the Merger). The exchange ratio formula is based on a $60.0 million valuation of Brickell and a $40.0 million valuation of Vical and is subject to adjustment based on the Vical Net Cash and Brickell Net Working Capital balances prior to the completion of the Merger.

Concurrent Financing; Funding Agreement

Concurrent with the execution of the Merger Agreement, Brickell and NovaQuest entered into the Funding Agreement pursuant to which NovaQuest committed, subject to the terms and conditions of the Funding Agreement, to provide up to $25.0 million in near-term research and development funding to Brickell in connection with sofpironium bromide in the Concurrent Financing, with $5.6 million of the commitment expected to be paid promptly following the closing of the Merger and the remaining portion of the commitment expected to be paid in quarterly payments equal to 67% of invoiced research and development expenses in connection with sofpironium bromide incurred during the following four fiscal quarters. Upon receipt of marketing approvals in the United States for sofpronium bromide, Brickell will be obligated to make certain milestone payments to NovaQuest totaling $37.5 million. Beginning in the fiscal quarter that is two years following the first commercial sale of a sofpronium bromide product, Brickell will be required to make low single digit revenue sharing payments based on annual net sales worldwide (except for Japan, China and certain other countries). Generally, if Brickell suspends or terminates its development program in respect of sofpironium bromide, Brickell will be required to pay NovaQuest $25.0 million plus interest of between 8% and 12%. However, in the event that Brickell terminates its development program for sofpromium bromide for certain reasons, including serious safety issues, a failure of the product’s Phase 3 studies, or the failure of FDA to approve the product, Brickell will not be obligated to make any payments to NovaQuest unless it subsequently resumes the development program.

152.

rights following an event of default include, among other things, foreclosing on Brickell’s assets in the United States relating to sofpironium bromide and, in certain circumstances, accelerating payment obligations under the Funding Agreement. NovaQuest also has the right to suspend its funding obligations under the Funding Agreement in the event of certain adverse developments relating to sofpironium bromide and in the event that certain of Brickell’s senior executives leave Brickell and we do not find replacements acceptable to NovaQuest. These provisions of the Funding Agreement are discussed in greater detail in the section titled “Risk Factors” in this proxy statement.

Key Components of Brickell’s Results of Operations

Collaboration Revenue

Collaboration revenues generally consist of revenues recognized under Brickell’s strategic collaboration agreements for the development and commercialization of its product candidates. Brickell’s strategic collaboration agreements generally outline overall development plans and include payments Brickell receives at signing, payments for the achievement of certain milestones, and royalties. For these activities and payments Brickell utilizes judgment to assess the nature of the performance obligations to determine whether the performance obligations are satisfied over time or at a point in time and, if over time, the appropriate method of measuring progress for purposes of recognizing revenue. Brickell has not recognized any royalty revenue to date. Other than the revenue Brickell may generate in connection with these agreements, Brickell does not expect to generate any revenue from any product candidates that it develops unless and until Brickell obtains regulatory approval and commercializes its products or enters into other collaborative agreements with third parties.

Research and Development

Research and development expenses principally consist of payments to third parties know as Clinical Research Organizations, or CROs. These CROs help plan, organize and conduct clinical and nonclinical studies under the direction of Brickell. Personnel costs, including wages, benefits and share-based compensation, related to Brickell’s research and development staff in support of product development activities are also included, as well as costs incurred for supplies,pre-clinical studies and toxicology tests, consultants, and facility and related overhead costs.

Below is a summary of Brickell’s research and development expenses by categories of costs for the periods presented. The other expenses category includes travel, lab and office supplies, clinical trial management software, license fees and other miscellaneous expenses.

Total research and development expenses	$	4,229	$	2,254	$	10,248	$	4,436	$	12,960	$	11,885

Brickell expects to increase its investment in research and development in order to advance sofpironium bromide through two identical Phase 3 pivotal studies in people with hyperhidrosis beginning in the fourth

153.

quarter of 2019 by working with CROs and hiring additional research and development staff. Brickell also plans to increase the number of clinical studies and other tests for developing additional product candidates. As a result, Brickell expects that its research and development expenses will increase for the foreseeable future.

General and Administrative

General and administrative expenses consist primarily of personnel costs, including wages, benefits and share-based compensation, related to Brickell’s executive, sales, marketing, finance and human resources personnel, as well as professional fees, including legal and accounting fees, and sublicensing fees.

Brickell expects its general and administrative expenses to increase in the near term, both in absolute dollars and as a percentage of revenue largely driven by hiring additional personnel to spot the growth of the business. There will also be significant additional expenses associated with operating as a public company. Such increases may include increased insurance premiums, investor relations expenses, legal and accounting fees associated with the expansion of Brickell’s business and corporate governance, financial reporting expenses, and expenses related to Sarbanes-Oxley and other regulatory compliance obligations.

Total Other Income (Expense)

Interest Expense

Interest expense consists primarily of interest and amortization of debt related to the loan and security agreement (the “Loan Agreement”) entered into with Hercules Capital, Inc. (the “Lender”) under which Brickell borrowed $7.5 million upon the execution of the Loan Agreement on February 18, 2016. The Loan Agreement’s applicable interest rate is variable based upon the greater of either (i) 9.2% and (ii) the sum of (a) the Prime Rate as reported in the Wall Street Journal minus 3.5%, plus (b) 9.2%. Payments by Brickell under the Loan Agreement were interest only until June 1, 2017, followed by equal monthly payments of principal and interest through the scheduled maturity date on September 1, 2019. The Loan Agreement is expected to be paid in full at approximately the same time as the consummation of the Merger.

Interest Income

Interest income consists primarily of interest earned on cash and cash equivalent balances. Brickell’s interest income will vary each reporting period depending on its average cash balances during the period and market interest rates. Brickell expects interest income to fluctuate in the future with changes in average cash balances and market interest rates.

Change in Fair Value of Warrant Liability

In connection with the Loan Agreement, Brickell issued warrants to the Lender, which are exercisable for 26,087 shares of Series C redeemable convertible preferred stock at a per share exercise price of $11.50.

In March 2019, Brickell initiated a convertible promissory notes offering, of up to $12.5 million in principal, pursuant to which Brickell issued unsecured convertible promissory notes (the “Convertible Notes”), bearing interest at 12.00% and maturing in one year and that can be converted into shares of SeriesC-1 redeemable convertible preferred stock or the most senior preferred equity outstanding at the time of conversion at the option of the holder at a conversion price of $10.72 per share. In addition, the Convertible Notes will automatically convert if a qualified financing of at least $15.0 million occurs before maturity, and such mandatory conversion price will equal 80% of the effective price per share paid in the qualified financing, but not to exceed $13.40 per share. In connection with the issuance of the full $12.5 million in Convertible Notes and based on the estimated price per share of Brickell common stock implied in the Merger, Brickell intends to issue warrants at 50% coverage, to acquire 2,493,665 shares of Brickell common stock. The warrants are exercisable for a term of five years at an exercise price of $14.74 or a 10% premium to the effective price per share paid in the qualified financing. At the effective time of the Merger, outstanding Convertible Notes and accrued interest will convert into shares of Vical common stock.

154.

Brickell accounts for the warrants as liabilities at their estimated fair value. The warrants are subject to remeasurement to fair value at each balance sheet date, and any fair value adjustments are recognized as changes in fair value of warrant liability in the statements of operations. Brickell will continue to adjust the liability for changes in fair value until the earlier of the exercise, expiration of the warrants or consummation of the Merger. At that time, the warrant liability will be adjusted to fair value in the statements of operations with the final fair value reclassified to equity.

Liquidity and Capital Resources

Brickell has incurred significant operating losses and has an accumulated deficit as a result of ongoing efforts to develop its product candidates, including conducting preclinical and clinical trials and providing general and administrative support for these operations. For the six months ended June 30, 2019 and 2018, Brickell had a net loss of $8.2 million and $3.0 million, respectively. For the years ended December 31, 2018 and 2017, Brickell had a net loss of $9.2 million and $11.1 million, respectively. As of June 30, 2019 and December 31, 2018, Brickell had an accumulated deficit of $69.3 million and $71.6 million, respectively. As of June 30, 2019 and December 31, 2018, Brickell had cash and cash equivalents of $2.1 million and $8.1 million, respectively. Since inception, Brickell has financed operations primarily through sales of equity securities, convertible promissory notes and warrants, as well as payments received under strategic collaboration and licensing agreements. Brickell also entered into a loan and security agreement (the “Loan Agreement”) with Hercules Capital, Inc. (the “Lender”) under which Brickell borrowed $7.5 million upon the execution of the Loan Agreement on February 18, 2016. The Loan Agreement is expected to be paid in full at approximately the same time as the consummation of the Merger.

Brickell expects to continue to incur additional substantial losses in the foreseeable future as a result of its research and development activities. Brickell believes that the cash and cash equivalents as of June 30, 2019 along with the payments and proceeds expected to be received in connection with the Merger and the Funding Agreement, will be sufficient to fund its operations for at least the next twelve months from the issuance of the unaudited financial statements, however the Merger is subject to conditions such as a shareholder vote. Additional funding will be required in the future to maintain Brickell’s present and proposed research activities. There can be no assurance that additional equity or debt financing will be available on acceptable terms, if at all. If Brickell is unable to raise additional funding to meet the working capital needs in the future, Brickell will be forced to delay or reduce the scope of the research programs and/or limit or cease these operations.

Cash Flows for the Six Months Ended June 30, 2019 and 2018

Operating Activities

Net cash used in operating activities of $9.5 million during the six months ended June 30, 2019 decreased compared to cash provided by operating activities of $13.0 million during the same period in the prior year primarily due to $20.6 million in milestone and research and development funding received from Kaken during the six months ended June 30, 2018, as well as changes in current liabilities.

Investing Activities

There were no significant investing activities during the six months ended June 30, 2019 or 2018.

Financing Activities

Net cash provided by financing activities of $3.5 million during the six months ended June 30, 2019 increased compared to net cash used in financing activities of $0.5 million during the prior year. The increase was primarily related to proceeds of $5.1 million from the issuance of convertible promissory notes, partially offset by payments of $1.6 million towards the note payable pursuant to the Loan Agreement.

Net cash used by financing activities of $0.5 million during the six months ended June 30, 2018 was primarily related to payments towards the note payable pursuant to the Loan Agreement.

Cash Flows for the Year Ended December 31, 2018 and 2017

Operating Activities

Net cash provided by operating activities of $4.0 million during the year ended December 31, 2018 was primarily related to an increase in deferred revenue of $9.7 million due to timing of payments received from the Collaboration Agreement, an increase in accounts payable of $2.8 million, andnon-cash charges for stock-based compensation of $0.7 million and amortization of debt discounts and financing costs of $0.5 million, which was partially offset by a net loss of $9.2 million.

Net cash used in operating activities of $9.4 millionduring the year ended December 31, 2017 consisted primarily of a net loss of $11.1 million, offset bynon-cash charges for stock-based compensation of $0.9 and amortization of debt discounts and financing costs of $0.4 million. Changes in operating assets and liabilities were unfavorable to cash flows from operations primary due to a decrease in deferred revenue of $2.6 million, and a partial increase in accounts payable and accrued expenses of $1.8 million.

159.

Investing Activities

There were no significant investing activities during the year ended December 31, 2018 or 2017.

Financing Activities

Net cash used in financing activities of $1.3 million during the year ended December 31, 2018 was primarily related to principal payments made on notes payable of $1.3 million.

Net cash provided by financing activities of $6.4 million during the year ended December 31, 2017 was primarily related to proceeds from the issuance of redeemable convertible preferred stock, net of issuance costs of $7.8 million, which was partially offset by principal payments made on notes payable of $1.4 million.

Contractual Obligations and Commitments

The following is a summary of the contractual obligations as of June 30, 2019 and the effect such obligations are expected to have on the liquidity and cash flows in future periods:

Total	$	4,076	$	3,952	$	124	$	—	$	—

Under various agreements, including the Funding Agreement, Brickell will be required to make milestone payments and pay royalties and other amounts to third parties, including NovaQuest. Brickell has not included any contingent payment obligations, such as milestones or royalties, in the table above as the amount, timing and likelihood of such payments are not known.

Brickell enters into contracts in the normal course of business with CROs for clinical trials, preclinical research studies and testing, chemistry and manufacturing, and other services and products for operating purposes. These contracts generally provide for termination upon notice, and therefore Brickell believes that thenon-cancelable obligations under these agreements are not material.

Off-Balance Sheet Arrangements

As of June 30, 2019 and December 31, 2018, Brickell had not been involved in any materialoff-balance sheet arrangements, as defined in the rules and regulations of the SEC.

Critical Accounting Policies and Estimates

Brickell has prepared the financial statements in accordance with U.S. GAAP. The preparation of these financial statements requires Brickell to make estimates, assumptions and judgments that affect the reported amounts of assets, liabilities, expenses and related disclosures at the date of the financial statements. On an ongoing basis, management evaluates its critical estimates, including those related to revenue recognition, accrued research and development expenses, convertible notes, redeemable convertible preferred stock, warrants and stock-based compensation. Brickell bases its estimates on its historical experience and also on assumptions that it believes are reasonable; however, actual results differ materially from these estimates under different assumptions or conditions.

For information on Brickell’s significant accounting policies, please refer Note 2 to Brickell’s financial statements.

160.

Revenue Recognition

Brickell currently recognizes revenue generated primarily from licensing fees received under Brickell’s Collaboration Agreement with Kaken. The terms of the agreements include non-refundable upfront fees, funding of research and development activities, payments based upon achievement of milestones, and royalties on net product sales.

Under Accounting Standards Update (“ASU”)No. 2014-09, Revenue from Contracts with Customers (“Topic 606”), an entity recognizes revenue when its customer obtains control of promised goods or services, in an amount that reflects the consideration which the entity expects to receive in exchange for those goods or services. To determine revenue recognition for arrangements that an entity determines are within the scope of Topic 606, the entity performs the following five steps: (i) identify the promised goods or services in the contract with a customer; (ii) identify the performance obligations in the contract; (iii) determine the transaction price, including the constraint on variable consideration; (iv) allocate the transaction price to the performance obligations in the contract; and (v) recognize revenue when or as the entity satisfies a performance obligation.

At contract inception, Brickell assesses the goods or services promised within each contract, determines those that are performance obligations, and assesses whether each promised good or service is distinct. Brickell then recognizes as revenue the amount of the transaction price that is allocated to the respective performance obligation when or as the performance obligation is satisfied. Brickell utilizes judgment to assess the nature of the performance obligation to determine whether the performance obligation is satisfied over time or at a point in time and, if over time, the appropriate method of measuring progress. Brickell evaluates the measure of progress each reporting period and, if necessary, adjusts the measure of performance and related revenue recognition.

Licenses of intellectual property

If a license to Brickell’s intellectual property is determined to be distinct from the other performance obligations identified in the arrangement, Brickell recognizes revenues from non-refundable, up-front fees allocated to the license when the license is transferred to the customer, and the customer can use and benefit from the license.

Milestone payments

At the inception of each arrangement that includes milestone payments, Brickell evaluates whether the milestones are considered probable of being achieved and estimates the amount to be included in the transaction price using the most likely amount method. If it is probable that a significant revenue reversal would not occur, the value of the associated milestone (such as a regulatory submission) is included in the transaction price, which is then allocated to each performance obligation. Milestone payments that are not within the control of Brickell or its partner, such as approvals from regulators, are not considered probable of being achieved until those approvals are received. At the end of each subsequent reporting period, Brickell re-evaluates the probability of achievement of such development milestones and, if necessary, adjusts its estimate of the overall transaction price. Any such adjustments are recorded on a cumulative catch-up basis, which would affect license, collaboration, and other revenues and earnings in the period of adjustment and in future periods through the end of the performance obligation period.

Royalties

For arrangements that include sales-based royalties, including milestone payments based on the level of sales, and where the license is deemed to be the predominant item to which the royalties relate, Brickell recognizes revenue at the later of (a) when the related sales occur, or (b) when the performance obligation to which some or all of the royalty has been allocated has been satisfied (or partially satisfied). To date, Brickell has not recognized any royalty revenue resulting from any of its licensing arrangements.

161.

For a complete discussion of accounting for collaborative licensing agreements, see Note 2, to Brickell’s financial statements. Brickell’s revenue to date has been generated primarily from collaboration and licensing fees received under its Collaboration Agreement with Kaken.

Research and Development

Research and development costs are charged to expense when incurred and consist of costs incurred for independent and collaborative research and development activities. The major components of research and development costs include formulation development, clinical studies, clinical manufacturing costs, salaries and employee benefits, toxicology studies, allocations of various overhead and occupancy costs. Research costs typically consist of applied research, preclinical, and toxicology work. Pharmaceutical manufacturing development costs consist of product formulation, chemical analysis, and the transfer and scale up of manufacturing at contract manufacturers.

As part of the process of recording research and development costs, Brickell is required to estimate and accrue expenses, the largest of which are research and development expenses. This process involves the following:

•

communicating with appropriate internal personnel to identify services that have been performed on Brickell’s behalf and estimating the level of service performed and the associated cost incurred for the service when Brickell has not yet been invoiced or otherwise notified of actual cost;

•

estimating and accruing expenses in Brickell’s financial statements as of each balance sheet date based on facts and circumstances known to Brickell at the time; and

•

periodically confirming the accuracy of Brickell’s estimates with service providers and making adjustments, if necessary.

Examples of estimated research and development expenses that Brickell accrues include:

•

payments to CROs in connection with preclinical and toxicology studies and clinical trials;

•

payments to investigative sites in connection with clinical trials;

•

payments to CMOs in connection with the production of clinical trial materials; and

•

professional service fees for consulting and related services.

Brickell bases its expense accruals related to clinical trials on Brickell’s estimates of the services received and efforts expended pursuant to contracts with multiple research institutions and CROs that conduct and manage clinical trials on Brickell’s behalf. The financial terms of these agreements vary from contract to contract and may result in uneven payment flows. Payments under some of these contracts depend on factors such as the successful enrollment of patients and the completion of clinical trial milestones. In accruing costs, Brickell estimates the time period over which services will be performed and the level of effort to be expended in each period. If Brickell does not identify costs that Brickell has begun to incur or if Brickell underestimates or overestimates the level of services performed or the costs of these services, Brickell’s actual expenses could differ from estimates.

To date, Brickell has not experienced significant changes in its estimates of accrued research and development expenses after a reporting period. However, due to the nature of estimates, Brickell cannot assure that Brickell will not make changes to its estimates in the future as Brickell becomes aware of additional information about the status or conduct of its clinical trials and other research activities.

Stock-Based Compensation

Stock options granted to employees and non-employees under the Brickell’s stock option plan are accounted for by using a fair value based method. Stock-based payments to employees and non-employees are measured

162.

based on their fair values at the date of grant, net of forfeitures, and are recorded on a straight-line basis over the requisite employee service period. Brickell uses the Black-Scholes option pricing model to estimate the fair value of stock options at the grant date. For performance-based awards where the vesting of the options may be accelerated upon the achievement of certain milestones, vesting and the related stock-based compensation is recognized as an expense when it is probable the milestone will be met.

When awards are modified, Brickell compares the fair value of the affected award measured immediately prior to modification to its value after modification. To the extent that the fair value of the modified award exceeds the original award, the incremental fair value of the modified award is recognized as compensation on the date of modification for vested awards, and over the remaining vesting period for unvested awards.

One of the inputs in the Black-Scholes option pricing model is the estimated fair value of common stock. Because there has been no public market for the Brickell’s common stock, the fair value is determined by a third-party valuation firm at each balance sheet date by considering a number of objective and subjective factors, including valuation of comparable companies, sales of capital stock to unrelated third parties, operating and financial performance, the lack of liquidity of capital stock, and general and industry specific economic outlook, among other factors. The valuations are prepared in accordance with methodologies outlined in the American Institute of Certified Public Accountants Practice Aid, Valuation of Privately-Held-Company Equity Securities Issued as Compensation (the “Practice Aid”).

There are significant judgments and estimates inherent in the determination of these valuations. These judgments and estimates include assumptions regarding Brickell’s future performance, including the successful completion of future clinical trials and the time to liquidity, as well as the determination of the appropriate valuation methods at each valuation date. If different assumptions were used, Brickell’s valuation could have been different. The foregoing valuation methodologies are not the only methodologies available, and they will not be used to value the combined organization’s common stock if the merger is completed. Accordingly, stockholders and investors should not place undue reliance on the foregoing valuation methodologies as an indicator of the combined organization’s future stock price.

Redeemable Convertible Preferred Stock

Redeemable convertible preferred stock is classified as a mezzanine instrument outside of the Brickell’s capital accounts. Accretion of redeemable convertible preferred stock includes the accrual of dividends on and accretion of issuance costs of the Brickell’s redeemable convertible preferred stock. The carrying values of the redeemable convertible preferred stock are increased by periodic accretion or reduction to their respective redemption values based on the current estimated redemption value. These increases or decreases are recorded as charges or recoveries against additional paid-in capital balance until the additional paid-in capital balance is reduced to zero. At that time, additional accretion adjustments are recorded to accumulated deficit.

Convertible Debt

From time to time, Brickell enters into debt financing transactions whereby such convertible debt contains conversion features into preferred or common shares. Brickell accounts for such instruments underASC, 470-20 “Debt with Conversion and Other Options” which requires companies to bifurcate conversion options from their host instruments and account for them as free standing derivative financial instruments according to certain criteria. Brickell accounts for instruments issued with convertible debt that have been determined to be free standing derivative financial instruments or embedded derivatives in accordance with ASC 815 “Derivatives and Hedging”. Under ASC 815, a portion of the proceeds received upon the issuance of the convertible debt is allocated to the fair value of the derivative and a corresponding discount is recorded on the convertible debt. The derivative is subsequently marked to market at each reporting date based on current fair value, with the changes in fair value reported in the statements of operations.

163.

During the six months ended June 30, 2019, Brickell issued an aggregate of $5.1 million of convertible debt and warrants to investors containing a redemption feature, which was deemed an embedded derivative and required Brickell to bifurcate and separately account for the embedded derivative as a liability. The warrants also required fair value accounting and were accounted as a liability. The discount on the debt is amortized through interest expense based on the effective interest method.

Board Leadership

UNAUDITED PRO FORMA COMBINED FINANCIAL STATEMENTS

The following information and all other information contained in this proxy statement does not give effect to a Reverse Split described in Proposal No. 1.

The unaudited pro forma combined financial statements were prepared in accordance with the regulations of the SEC. The following unaudited pro forma combined financial statements give effect to the proposed Merger. The transaction is expected to be accounted for as a reverse recapitalization under existing GAAP, which is subject to change and interpretation. Accordingly, for accounting purposes, the transaction will be treated as the equivalent of Brickell issuing shares of common stock for the net assets, primarily cash and investments, accompanied by a recapitalization. The net assets of Vical will be recognized at fair value (which is expected to be consistent with carrying value), with no goodwill or intangible assets recorded. The unaudited pro forma combined financial statements presented below are based upon the historical financial statements of Brickell and Vical, included in this proxy statement, adjusted to give effect to the reverse recapitalization, for accounting purposes. The pro forma adjustments are described in the accompanying notes presented on the following pages.

The unaudited pro forma combined balance sheet as of June 30, 2019, and the unaudited pro forma combined statement of operations and comprehensive loss for the six months June 30, 2019 and the year ended December 31, 2018 presented herein are based on the historical financial statements of Brickell and Vical, adjusted to give effect to the proposed reverse recapitalization. The pro forma assumptions and adjustments are described in the accompanying notes presented in the following pages.

Brickell has been determined to be the accounting acquirer based on an evaluation of the facts of the Merger. Upon completion of the Merger, Brickell securityholders and NovaQuest, collectively, will hold approximately 60% of the aggregate number of shares of Vical common stock (on a fully diluted basis using the treasury stock method in instances other than with respect to the NovaQuest Warrants and certain equity issuances by Brickell following the signing of the Merger Agreement and prior to the completion of the Merger) and the Brickell directors and management will hold a majority of board seats and all key positions in the management of the combined company. Other factors were considered, including the purpose and intent of the Merger, composition of the post-merger stockholders and the location of the combined company’s headquarters noting that the preponderance of the evidence is indicative that Brickell is the accounting acquirer.

After the closing of the Merger, the stockholders’ equity of Brickell will be restated to give effect to the exchange of shares in the Merger and the historical results of operations of Brickell will be reflected as the results of operations of the combined company following the Merger.

The Brickell balance sheet as of June 30, 2019 and statement of operations for the six months ended June 30, 2019 were derived from its unaudited financial statements, included elsewhere in this proxy statement. The statement of operations and comprehensive loss for year ended December 31, 2018 were derived from its audited financial statements, included elsewhere in this proxy statement.

The Vical balance sheet as of June 30, 2019 and statement of operations for the six months ended June 30, 2019 were derived from its unaudited financial statements, included in the Vical10-Q2, which is incorporated by reference in this proxy statement. The statement of operations and comprehensive loss for year ended December 31, 2018 were derived from its audited consolidated financial statements included in theVical 10-K, incorporated by reference in this proxy statement.

The historical financial statements have been adjusted to give pro forma effect to events that are (i) directly attributable to the Merger, (ii) factually supportable, and (iii) with respect to the statement of operations, expected to have a continuing impact on the combined results. These adjustments include estimates for the issuance of shares of common stock in the Merger resulting from the anticipated issuance of securities by Brickell prior to the closing of the Merger. Differences between these preliminary estimates and the final

173.

accounting will occur and could have a material impact on the accompanying unaudited pro forma combined financial statements and the combined company’s future results of operations and financial position. The actual amounts recorded as of the completion of the Merger may differ materially from the information presented in these unaudited pro forma combined financial statements as a result of the timing of completion of the Merger, issuances of common stock, convertible notes, warrants or options to purchase common stock and other changes in the Vical or Brickell net assets that occur prior to the completion of the Merger, which could cause material differences in the information presented below.

The unaudited pro forma combined financial statements do not give effect to the potential impact of current financial conditions, regulatory matters, operating efficiencies or other savings or expenses that may be associated with the Merger. The unaudited pro forma combined financial data also do not include any integration costs. The unaudited pro forma combined financial statements have been prepared for illustrative purposes only and are not necessarily indicative of the financial position or results of operations in future periods or the results that actually would have been realized had Brickell and Vical been a combined company during the specified period. The unaudited pro forma combined financial statements, including the notes thereto, should be read in conjunction with the Brickell historical audited financial statements for the year ended December 31, 2018 included elsewhere in this proxy statement and in conjunction with the Vical historical audited consolidated financial statements included in Vical10-K.

The unaudited pro forma combined financial statements also do not give effect to the Concurrent Financing. In connection with the Concurrent Financing, immediately following the closing of the Merger, Vical will issue the NovaQuest Warrants. The number of shares of Vical common stock underlying the NovaQuest Warrants will be based on 10% warrant coverage on the $25.0 million NovaQuest funding commitment and the final exchange ratio for the Merger, and the exercise price of the NovaQuest Warrants will be determined based on a 10% premium to the Brickell per share price of common stock implied in the Merger, as adjusted for the Exchange Ratio.

NOTES TO UNAUDITED PRO FORMA COMBINED FINANCIAL INFORMATION

1. Description of Transaction and Basis of Presentation

Description of Transaction

On June 2, 2019, Brickell entered into the Merger Agreement with Vical and Merger Sub. Pursuant to the terms and subject to the conditions set forth in the Merger Agreement, Merger Sub will merge with and into Brickell, with Brickell surviving as a wholly owned subsidiary of Vical.

At the effective time of the Merger, each outstanding share of the capital stock of Brickell will be converted into the right to receive a number of shares of Vical common stock as determined pursuant to the Exchange Ratio described in the Merger Agreement, and all outstanding options, warrants or other rights to purchase shares of capital stock of Brickell, will be exchanged for rights to acquire Vical common stock based on the Exchange Ratio described in the Merger Agreement. No fractional shares of Vical common stock will be issued in connection with the Merger, and holders of Brickell capital stock will be entitled to receive cash for any fractional share ownership in lieu of stock thereof.

Upon completion of the Merger, Brickell securityholders and NovaQuest, collectively, will hold approximately 60% of the aggregate number of shares of Vical common stock, and to the securityholders of Vical as of immediately prior to the Merger will hold approximately 40% of the aggregate number of shares of Vical common stock (in each case on a fully diluted basis using the treasury stock method in instances other than with respect to the NovaQuest Warrants and certain equity issuances by Brickell following the signing of the Merger Agreement and prior to the completion of the Merger).

Basis of Presentation

Based on the terms of the Merger, the transaction will be treated as a reverse recapitalization of Brickell in accordance with accounting principles generally accepted in the United States.

The pro forma adjustments are preliminary and have been prepared to illustrate the estimated effect of the Merger. To the extent there are significant changes to the combined company’s business prior to or following completion of the Merger, the assumptions set forth in the unaudited pro forma combined financial statements could change significantly.

The unaudited pro forma combined balance sheet as of June 30, 2019 combines the historical balance sheets of Brickell and Vical as of June 30, 2019 as if the Merger had been completed on that date.

The unaudited pro forma combined statement of operations and comprehensive loss for the year ended December 31, 2018 combine the historical statements of operations and comprehensive loss of Brickell and Vical for their respective periods and give pro forma effect to the Merger as if it had been completed on January 1, 2018.

The unaudited pro forma combined statement of operations and comprehensive loss for the six months ended June 30, 2019 combine the historical statements of operations and comprehensive loss of Brickell and Vical for their respective periods and give pro forma effect to the Merger as if it had been completed on January 1, 2018.

The unaudited pro forma combined financial statements assume an exchange ratio of 2.3035 of Vical common stock for each share of Brickell common stock. The exchange ratio does not give any effect to the Vical proposed reverse common stock split. The Exchange Ratio, calculated pursuant to the formula set forth in the Merger Agreement, is intended to allocate to the former Brickell securityholders and NovaQuest, collectively,

178.

approximately 60% of the aggregate number of shares of Vical common stock, and to the securityholders of Vical as of immediately prior to the Merger approximately 40% of the aggregate number of shares of Vical common stock (in each case on a fully diluted basis using the treasury stock method in instances other than with respect to the NovaQuest Warrants and certain equity issuances by Brickell following the signing of the Merger Agreement and prior to the completion of the Merger). This Exchange Ratio is an estimate only and the final Exchange Ratio will be determined pursuant to Merger Agreement. This Exchange Ratio assumes the following:

•

Exchange of 1,706,251 shares of Brickell common stock outstanding as of June 30, 2019

•

Conversion of 3,639,905 shares of Brickell preferred stock outstanding as of June 30, 2019

•

Conversion of $14.4 million of accrued dividends through May 31, 2019 on Brickell’s preferred stock at the Merger price per share of Brickell common stock

The estimated Exchange Ratio and pro forma shares of common stock outstanding in these unaudited pro forma financial statements is also impacted by estimated securities, which are assumed to be issued prior to the closing of the Merger and which could vary including:

•

The issuance by Brickell of additional options to purchase common stock with an exercise price equal to the Merger price per share of Brickell common stock

•

The issuance of the warrants in accordance with the Funding Agreement with an exercise price equal to a 10% premium to the Brickell price per share of common stock implied in the Merger, as adjusted for the Exchange Ratio

•

The raise of the maximum of $12.5 million of convertible notes and related warrants to purchase Brickell common stock and conversion of these notes and minimum accrued interest (nine months at 9%) at 80% of the Merger price per share of Brickell common stock ($5.1 million of such notes were outstanding at June 30, 2019)

2. Pro Forma Combined Earnings Per Share

The pro forma combined weighted average share outstanding included in the calculation of basic and diluted pro forma combined earnings (loss) per share consists of the following:


	Year ended December 31, 2018
Historical Vical weighted average shares		21,842,000
Shares issued to Brickell		36,808,000

Pro forma weighted common shares, basic and diluted		58,650,000


	Six months ended June 30, 2019
Historical Vical weighted average shares		22,404,000
Shares issued to Brickell		36,246,000

Pro forma weighted common shares, basic and diluted		58,650,000

3. Pro Forma Adjustments

The unaudited pro forma combined financial statements include pro forma adjustments to give effect to certain significant transactions as a direct result of the proposed Merger and reverse recapitalization for accounting purposes.

179.

The pro forma adjustments reflecting the completion of the Merger are based upon the preliminary accounting analysis conclusion that the Merger should be accounted for as a reverse recapitalization and upon the assumptions set forth below.

The unaudited pro forma combined financial statements do not not give effect to a Reverse Split described in Proposal No. 1.

The pro forma adjustments are as follows:

A1:

To reflect vendor payments for strategic advisor, legal, accounting and other direct costs of Vical and Brickell related to the Merger, which are not recognized in the respective balance sheets as of June 30, 2019.

A2:

To reflect the elimination of Vical’s historical stockholders’ equity balances, including accumulated deficit.

A3:

To reflect accrual for Vical’s executive severance costs directly related to the Merger, which are not recognized in Vical’s balance sheets as of June 30, 2019.

A4:

To reflect the conversion of the Brickell convertible notes into common stock prior to the close of Merger and prior to the exchange of shares.

A5:

To reflect the exchange of shares of Brickell common and convertible preferred stock outstanding, immediately prior to the closing of the Merger for shares of Vical common stock upon closing of the Merger.

A6:

To reclassify Brickell’s warrant liability to equity upon the conversion of preferred stock to common stock upon the close of the Merger as the warrants are no longer expected to be required to be reflected as a liability upon becoming warrants to purchase common stock at a fixed exercise price.

A7:

To eliminate Merger cost incurred in the statement of operations, which are non-recurring.

180.

PRINCIPAL STOCKHOLDERS OF VICAL

Applicable percentage ownership is based on 12,446,989 shares of common stock outstanding at June 30, 2019, assuming the automatic conversion of all outstanding shares (including accrued dividends and conversion of notes and interest) of Brickell’s Series A Preferred Stock, Series B Preferred Stock, Series C Preferred Stock and SeriesC-1 Preferred Stock, on aone-for-one basis, into 3,066,246, 1,893,748, 1,726,918 and 1,546,845 shares of common stock, respectively.

HOUSEHOLDING OF PROXY MATERIALS

The SEC has adopted rules that permit companies and intermediaries (e.g., brokers) to satisfy the delivery requirements for proxy statements and annual reports with respect to two or more stockholders sharing the same address by delivering a single proxy statement addressed to those stockholders. This process, which is commonly referred to as “householding,” potentially means extra convenience for stockholders and cost savings for companies.

A number of brokers with account holders who are Vical stockholders will be householding our proxy materials. A single proxy statement will be delivered to multiple stockholders sharing an address unless contrary instructions have been received from the affected stockholders. Once you have received notice from your broker that they will be householding communications to your address, householding will continue until you are notified otherwise or until you revoke your consent. If, at any time, you no longer wish to participate in householding and would prefer to receive a separate proxy statement and annual report, please notify your broker, direct your written request to Vical Incorporated, Investor Relations, 10390 Pacific Center Court, San Diego, California 92121-4340 or contact Vijay B. Samant at(858) 646-1100. Stockholders who currently receive multiple copies of the proxy statement at their address and would like to request householding of their communications should contact their broker.

FUTURE STOCKHOLDER PROPOSALS

To be considered for inclusion in our proxy materials for our 2019 Annual Meeting of Stockholders, your proposal must be submitted in writing to our Secretary at Brickell Biotech, Inc., 5777 Central Avenue, Suite 102, Boulder, Colorado, 80301. If you wish to submit a proposal (including a director nomination), your proposal generally must be submitted in writing to the same address not fewer than 60 nor more than 90 days prior to the date approved by the board of directors to hold the 2019 Annual Meeting of Stockholders; provided, that if we provide fewer than 60 days’ notice of such date, your proposal (including a director nomination) must be received by our Secretary not later than the tenth day following the day on which the notice of the date of the 2019 Annual Meeting of Stockholders is mailed or publicly disclosed. Please review our current bylaws, which contain additional requirements regarding advance notice of stockholder proposals and nominations.

185.

NOTES TO UNAUDITED FINANCIAL STATEMENTS

NOTE 1.

ORGANIZATION AND NATURE OF OPERATIONS

Brickell Biotech, Inc. (the “Company”) was incorporated in the state of Delaware and commenced activities on September 17, 2009. The Company is aclinical-stage pharmaceutical company focused on developing of innovative and differentiated therapeutics for the treatment of debilitating skin diseases. The Company’s pipeline consists of potential novel therapeutics for hyperhidrosis, cutaneous T-cell lymphoma, psoriasis, and other prevalent dermatological conditions. The Company’s pivotal Phase 3-ready clinical-stage product candidate, sofpironium bromide, is a new molecular entity and “soft” drug that belongs to a class of medications called anticholinergics. The Company is developing sofpironium bromide as a potential best-in-class, self-administered, once daily, topical prescription hyperhidrosis therapy for the treatment of primary axillary hyperhidrosis. The Company’s operations to date have been limited to business planning, raising capital, developing its pipeline assets (in particular sofpironium bromide), identifying product candidates, and other research and development. The Company is headquartered in Boulder, Colorado.

Agreement and Plan of Merger

On June 2, 2018, the Company, Victory Subsidiary, Inc. (“Merger Sub”), and Vical Incorporated (“Vical”), entered into the Merger Agreement, pursuant to which, among other matters, and subject to the satisfaction or waiver of the conditions set forth in the Merger Agreement, Merger Sub will merge with and into the Company, with the Company continuing as a wholly-owned subsidiary of Vical and the surviving corporation of the Merger.

Subject to the terms and conditions of the Merger Agreement, at the closing of the Merger, each outstanding share of the Company capital stock will be converted into the right to receive shares of Vical common stock (subject to the payment of cash in lieu of fractional shares and after giving effect to a reverse stock split of Vical common stock if determined necessary or appropriate by the Company, Vical and Merger Sub) such that, immediately following the Effective Time, preexisting Company stockholders, optionholders and warrantholders are expected to own, or hold rights to acquire, approximately 60% of the Fully-Diluted Common Stock of Vical, and preexisting Vical stockholders, optionholders and warrantholders are expected to own, or hold rights to acquire, approximately 40% of the Fully-Diluted Common Stock of Vical. Consummation of the Merger is subject to certain closing conditions, including, among other things, approval by the stockholders of Vical, and satisfaction of minimum net working capital thresholds by each of Vical and the Company. At the effective time of the Merger, the Board of Directors of Vical is expected to consist of seven members, five of whom will be designated by the Company and two of whom will be designated by Vical.

Contemporaneously with the execution and delivery of the Merger Agreement, and as a condition of the willingness of Vical to enter into the Merger Agreement, the Company entered into a funding agreement with NovaQuest Capital Management, LLC (“NovaQuest”) pursuant to which NovaQuest committed up to $25 million in research and development funding to the Company following the closing of the Merger. Concurrently with the closing of the funding agreement, the surviving corporation of the Merger will issue a warrant to NovaQuest to purchase shares of Vical common stock in an amount based on 10% warrant coverage on the $25.0 million funding commitment and the exchange ratio for the Merger.

Liquidity and Capital Resources

going concern. The Company has incurred significant operating losses and has an accumulated deficit as a result of ongoing efforts to develop product candidates, including conducting preclinical and clinical trials and providing general and administrative support for these operations. For the six months ended June 30, 2019, the Company had a net loss of $8.2 million and net cash used in operating activities of $9.5 million. As of June 30, 2019, the Company had cash and cash equivalents of $2.1 million and an accumulated deficit of $69.3 million.

The Company expects to continue to incur additional substantial losses in the foreseeable future as a result of the Company’s research and development activities. The Company believes that its cash and cash equivalents as of June 30, 2019 as well as cash received from the Merger and the transactions mentioned in Note 11 will be sufficient to fund its operations for at least the next twelve months from the issuance of the unaudited financial statements, however the Merger is subject to conditions such as a shareholder vote and while expected, this is not certain. Additional funding will be required in the future to maintain its present and proposed research activities. There can be no assurance that additional equity or debt financing will be available on acceptable terms, if at all. If the Company is unable to raise additional funding to meet its working capital needs in the future, it will be forced to delay or reduce the scope of its research programs and/or limit or cease its operations. These factors raise substantial doubt about the Company’s ability to continue as a going concern for a period of twelve months subsequent to the issuance of these financial statements.

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Basis of Presentation

The accompanying unaudited condensed financial statements are presented in U.S. dollars and have been prepared in accordance with accounting principles generally accepted in the United States of America (“US GAAP”) and applicable rules and regulations of the U.S. Securities and Exchange Commission (“SEC”) for interim reporting. As permitted under those rules and regulations, certain footnotes or other financial information normally included in financial statements prepared in accordance with US GAAP have been condensed or omitted. These condensed financial statements have been prepared on the same basis as our annual financial statements and, in the opinion of our management, reflect all adjustments, consisting only of normal recurring adjustments, which are necessary for a fair presentation of our financial information. The results of operations for the three and six months ended June 30, 2019 are not necessarily indicative of the results to be expected for the full year ending December 31, 2019 or any other future period. The condensed balance sheet as of June 30, 2019 has been derived from financial statements at that date but does not include all of the information required by US GAAP for complete financial statements.

Risks and Uncertainties

The Company’s business is subject to significant risks common to early-stage companies in the pharmaceutical industry including, but not limited to, the ability to develop appropriate formulations, scale up and production of the compounds, dependence on collaborative parties, uncertainties associated with obtaining and enforcing patents, clinical success, the lengthy and expensive regulatory approval process, compliance with regulatory requirements, competition from other products; uncertainty of broad adoption of its approved products, if any, by physicians and patients; significant competition; ability to manage third-party manufacturers, suppliers and contract research organizations (“CROs”) and obtaining additional financing to fund the Company’s efforts.

The product candidates developed by the Company require approvals from the FDA and foreign regulatory agencies prior to commercial sales in the United States or foreign jurisdictions, respectively. There can be no assurance that the Company’s current and future product candidates will receive the necessary approvals. If the Company is denied approval or approval is delayed, it may have a material adverse impact on the Company’s business and its financial condition.

for which it receives regulatory approval. There can be no assurance that such financing will be available or will be at terms acceptable by the Company.

Fair Value Measurements

Fair value is the price that the Company would receive to sell an asset or pay to transfer a liability in a timely transaction with an independent counterparty in the principal market or in the absence of a principal market, the most advantageous market for the asset or liability. Athree-tier hierarchy is established to distinguish between (1) inputs that reflect the assumptions market participants would use in pricing an asset or liability developed based on market data obtained from sources independent of the reporting entity (observable inputs) and (2) inputs that reflect the reporting entity’s own assumptions about the assumptions market participants would use in pricing an asset or liability developed based on the best information available in the circumstances (unobservable inputs), and establishes a classification of fair value measurements for disclosure purposes.

The hierarchy is summarized in the three broad levels listed below.

Level 1—quoted prices in active markets for identical assets and liabilities

Level 2—other significant observable inputs (including quoted prices for similar assets and liabilities, interest rates, credit risk, etc.)

Level 3—significant unobservable inputs (including the Company’s own assumptions in determining the fair value of assets and liabilities)

The following tables set forth the fair value of the Company’s financial assets and liabilities measured at fair value on a recurring basis based on the three-tier fair value hierarchy as of June 30, 2019 and December 31, 2018 (in thousands):

Fair Value of Financial Instruments

The following methods and assumptions were used by the Company in estimating the fair values of each class of financial instrument disclosed herein:

Money market funds—The carrying amounts reported in the balance sheets approximate their fair values due to theirshort-term nature and/or market rates of interest (Level 1 of the fair value hierarchy).

Contingent consideration—These amounts represent future payments in conjunction with various business combinations. The ultimate amount of future payments is based on specified future criteria, such as the achievement of certain future development and regulatory milestones. The Company evaluates its estimates of the fair value of contingent consideration on a periodic basis. The fair value of the contingent consideration was determined by a third-party valuation firm applying the income approach. This approach estimates the fair value of the contingent consideration related to the achievement of future development and regulatory milestones by assigning an achievement probability and date of expected completion to each potential milestone and discounting the associated cash payment to its present value using a risk-adjusted rate of return. The probability of success of each milestone assumes that the prerequisite developmental milestones are successfully completed and is based on the asset’s current stage of development and anticipated regulatory requirements. The probability of success for each milestone is determined by multiplying the preceding probabilities of success. The unobservable inputs (Level 3 of the fair value hierarchy) to the valuation models that have the most significant effect on the fair value of the Company’s contingent consideration are the probabilities that certainin-process development projects will meet specified development milestones, including ultimate approval by the FDA, with individual cumulative probabilities ranging from 2.1% to 20.9%. Other unobservable inputs used in this approach include: risk-adjusted discount rates ranging from 15.5% to 27.1% and estimates of the timing of the achievement of the various product development, regulatory approval and sales milestones.

Redeemable convertible preferred stock warrant liability—These amounts represent potential future obligations to transfer assets to the holders at a future date. The Company remeasures these warrants to current fair value at each balance sheet date, and any change in fair value is recognized as a change in fair value of warrant liability in the statements of operations. The Company estimated the fair value of these warrants at the respective balance sheet dates using the Black-Scholes option-pricing model (Level 3 of the fair value hierarchy table) (see further discussion in Note 6).

Inputs used to determine estimated fair value of the warrant liabilities include the estimated fair value of the underlying stock at the valuation date, the estimated term of the warrants, risk-free interest rates, expected dividends and the expected volatility of the underlying stock. The most significant unobservable inputs used in the fair value measurement of the convertible preferred stock warrant liability are the fair value of the underlying stock at the valuation date and the estimated term of the warrants. Generally, increases (decreases) in the fair value of the underlying stock and estimated term would result in a directionally similar impact to the fair value measurement.

The fair value of the outstanding convertible preferred stock warrants was remeasured as of each period end using the Black-Scholes option-pricing model with the following assumptions:


	2019			2018
Expected term (in years)		6.6			7.1
Expected volatility		30.00	%		30.00	%
Risk free interest rate		1.87	%		2.59	%
Expected dividend yield		—	%		—	%

F-9

Because there has been no public market for the Company’s convertible preferred stock, the third-party valuation firm has determined fair value of the convertible preferred stock at each balance sheet date by considering a number of objective and subjective factors, including valuation of comparable companies, sales of convertible preferred stock to unrelated third parties, operating and financial performance, the lack of liquidity of capital stock, and general and industry specific economic outlook, among other factors.

Remaining Term. The Company derived the expected term based on the time from the balance sheet date until the preferred stock warrant’s expiration date.

Expected Volatility. Since the Company was a private entity with no historical data regarding the volatility of its preferred stock, the expected volatility used is based on volatility of a group of similar entities. In evaluating similarity, the Company considered factors such as industry, stage of life cycle and size.

Risk-Free Interest Rate. The risk-free interest rate is based on U.S. Treasuryzero-coupon issues with remaining terms similar to the expected term of the warrants.

Expected Dividend Rate. The Company has never paid any dividends and does not plan to pay dividends in the foreseeable future and, therefore, used an expected dividend rate of zero in the valuation model.

Derivative liability—These amounts represent potential future obligations to transfer assets to the holders at a future date. The fair value of the derivative liability has historically been determined by a third-party valuation firm (Level 3 of the fair value hierarchy table) (see further discussion in Note 5). Because there has been no public market for the Company’s common stock, the third-party valuation firm has determined fair value of the stock at each balance sheet date by considering a number of objective and subjective factors, including valuation of comparable companies, sales of common stock to unrelated third parties, operating and financial performance, the lack of liquidity of capital stock, and general and industry specific economic outlook, among other factors. The derivative liability ismarked-to-market each measurement period and any change in fair value is recorded in the statements of operations.

The fair value of the derivative liability as of June 30, 2019 was determined using the following assumptions: contractual term of 0.2 years, expected volatility of 70.00%, risk-free rate of 1.75%, and expected dividend yield of 0%.

Common stock warrant liability—These amounts represent potential future obligations to transfer assets to the holders at a future date. The fair value of the warrants has historically been determined by a third-party valuation firm (Level 3 of the fair value hierarchy table) (see further discussion in Note 5). Because there has been no public market for the Company’s common stock, the third-party valuation firm has determined fair value of the stock at each balance sheet date by considering a number of objective and subjective factors, including valuation of comparable companies, sales of common stock to unrelated third parties, operating and financial performance, the lack of liquidity of capital stock, and general and industry specific economic outlook, among other factors. These warrants are remeasured to fair value at each balance sheet date, and any change in fair value is recognized as a change in fair value of warrant liability in the statements of operations. The Company estimated the fair value of these warrants at the respective balance sheet dates using the Black-Scholes option-pricing model.

Inputs used to determine estimated fair value of the warrant liabilities include the estimated fair value of the underlying stock at the valuation date, the estimated term of the warrants, risk-free interest rates, expected dividends and the expected volatility of the underlying stock. The most significant unobservable inputs used in the fair value measurement of the warrant liability are the fair value of the underlying stock at the valuation date and the estimated term of the warrants. Generally, increases (decreases) in the fair value of the underlying stock and estimated term would result in a directionally similar impact to the fair value measurement.

The fair value of the warrants as of June 30, 2019 was determined using the following assumptions: contractual term of 4.6 years, expected volatility of 70.00%, risk-free rate of 1.75%, and expected dividend yield of 0%.

Leases

On January 1, 2019, the Company adopted Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) 842, Leases (“ASC 842), using the modified retrospective method for all lease arrangements at the beginning of the period of adoption. Results for reporting periods beginning January 1, 2019 are presented under ASC 842, while prior period amounts were not adjusted and continue to be presented in accordance with the Company’s historical accounting under ASC Topic 840, Leases. ASC 842 had an impact on the Company’s Condensed Balance Sheet but did not have a significant impact on the Company’s net loss.

Under ASC 842, the Company determines if an arrangement is a lease at inception. Leases with a term greater than one year are recognized on the balance sheet asright-of-use assets, lease liabilities and, if applicable, long-term lease liabilities. The Company has elected the practical expedient not to recognize on the balance sheet leases with terms ofone-year or less and not to separate lease components andnon-lease components for long-term real-estate leases. Lease liabilities and their correspondingright-of-use assets are recorded based on the present value of lease payments over the expected lease term. The interest rate implicit in lease contracts is typically not readily determinable. As such, the Company estimates the incremental borrowing rate based on industry peers in determining the present value of lease payments. The Company’s facility operating lease has one single component. The lease component results in aright-of-use asset being recorded on the balance sheet and amortized as lease expense on a straight-line basis in the Company’s statements of operations.

Redeemable Convertible Preferred Stock

Redeemable convertible preferred stock is classified as a mezzanine instrument outside of the Company’s capital accounts. Accretion of redeemable convertible preferred stock includes the greater of an adjustment to fair market value or the accrual of dividends on and accretion of issuance costs of the Company’s redeemable convertible preferred stock. The carrying values of the redeemable convertible preferred stock are increased or reduced by periodic accretion or reduction to their respective redemption values, using the effective interest method, from the date of issuance to the earliest date the holders can demand redemption. These increases are recorded as charges against additionalpaid-in capital balance until the additionalpaid-in capital balance is reduced to zero. At that time, additional accretion adjustments are recorded as additions to accumulated deficit.

Preferred stock issuance costs represent costs related to the Company issuing redeemable convertible preferred stock. These amounts are included as a reduction of redeemable convertible preferred stock and are amortized over the estimated redemption period. Amortization of preferred stock issuance costs amounted to approximately $20,000 for the six months ended June 30, 2019 and 2018.

Redeemable Convertible Preferred Stock Warrants

The Company accounts for warrants to purchase shares of its redeemable convertible preferred stock as liabilities at their estimated fair value because the underlying shares are redeemable, which may obligate the Company to transfer assets to the holders at a future date. The warrants are subject to remeasurement to fair value at each balance sheet date, and any fair value adjustments are recognized as change in fair value of redeemable convertible preferred stock warrant liability in the statements of operations. The Company will continue to adjust the liability for changes in fair value until the earlier of the exercise or expiration of the redeemable convertible preferred stock warrants, conversion of redeemable convertible preferred stock into common stock, or until holders of the redeemable convertible preferred stock can no longer trigger a deemed liquidation event. At that time, the redeemable convertible preferred stock warrant liability will be adjusted to fair value in the statements of operations with the final fair value reclassified to equity.

Revenue Recognition

The Company recognizes revenue upon the transfer of promised goods or services to customers in an amount that reflects the consideration to which the Company expects to be entitled in exchange for those goods or services. To determine revenue recognition for contracts with customers the Company performs the following five steps: (i) identify the contract(s) with a customer; (ii) identify the performance obligations in the contract; (iii) determine the transaction price; (iv) allocate the transaction price to the performance obligations in the contract; and (v) recognize revenue when (or as) the Company satisfies the performance obligations. At contract inception, the Company assesses the goods or services promised within each contract and assesses whether each promised good or service is distinct and determines those that are performance obligations. The Company then recognizes as revenue the amount of the transaction price that is allocated to the respective performance obligation when (or as) the performance obligation is satisfied.

To date, the Company’s drug candidates have not been approved for sale by the FDA and the Company has not generated or recognized any revenue from the sale of products.

In March 2015, the Company entered into a license and collaboration agreement with Kaken Pharmaceutical, Co., Ltd. (“Kaken”), which is referred to as the “Collaboration Agreement”. Under the Collaboration Agreement, the Company granted to Kaken an exclusive right to develop, manufacture and commercialize the Company’s sofpironium bromide compound (formerlyBBI-4000), a topical anticholinergic, in Japan and certain other Asian countries (the “Territory”). In exchange, Kaken paid the Company an upfront,non-refundable payment of $11.0 million (the “upfront fee”). In addition, the Company is entitled to receive aggregate payments of up to $10.0 million upon the achievement of specified development milestones, and $30.0 million upon the achievement of commercial milestones, as well as tiered royalties based on a percentage of net sales of licensed products in the Territory. The Collaboration Agreement further provides that Kaken will be responsible for funding all development and commercial costs for the program in the Territory and, until such time, if any, as Kaken elects to establish its own source of supply of drug product, Kaken can purchase product supply from the Company to perform allnon-clinical studies, and Phase I and Phase II clinical trials in Japan at cost. Kaken is also required to enter into negotiations with the Company, to supply the Company, at cost, with clinical supplies to perform Phase III clinical trials in the U.S.

from the license. For licenses that are bundled with other performance obligations, the Company utilizes judgment to assess the nature of the combined performance obligation to determine whether the combined performance obligation is satisfied over time or at a point in time and, if over time, the appropriate method of measuring progress for purposes of recognizing revenue. The Company evaluates the measure of progress each reporting period and, if necessary, adjust the measure of performance and related revenue recognition on a prospective basis.

Under Topic 606, the Company evaluated the terms of the Collaboration Agreement and the transfer of intellectual property and manufacturing rights (the “license”) was identified as the only performance obligation as of the inception of the agreement. The Company concluded that the license for the intellectual property was distinct from its ongoing supply obligations. The Company further determined that the transaction price under the arrangement was comprised of the $11.0 million upfront payment. The future potential milestone amounts were not included in the transaction price, as they were all determined to be fully constrained. As part of our evaluation of the development and regulatory milestones constraint, the Company determined that the achievement of such milestones is contingent upon success in future clinical trials and regulatory approvals, each of which is uncertain at this time. The Company willre-evaluate the transaction price each quarter and as uncertain events are resolved or other changes in circumstances occur. Future potential milestone amounts would be recognized as revenue from collaboration arrangements, if unconstrained. The remainder of the arrangement, which largely consisted of both parties incurring costs in their respective territories, provides for the reimbursement of the ongoing supply costs. These costs were representative of a collaboration arrangement outside of the scope of Topic 606 as it does not have the characteristics of a vendor and customer relationship. Reimbursable program costs are recognized proportionately with the delivery of drug substance and are accounted for as reductions to research and development expense and are excluded from the transaction price.

Under Topic 606, the entire transaction price of $11.0 million was allocated to the license performance obligation. The license was deemed to be delivered in 2015 in connection with the execution of the Collaboration Agreement and upon transfer of the underlying intellectual property the performance obligation was fully satisfied. As a result, a cumulative adjustment to reduce deferred revenue and the corresponding sublicensing costs of $2.7 million was recorded upon the adoption of Topic 606 on January 1, 2018. As of June 30, 2019, the Company does not have a deferred revenue or deferred sublicensing costs balance related to the upfront fee on the balance sheet.

In May 2018, the Company entered into an amendment to the Collaboration Agreement (as further amended, “Collaboration Agreement”), pursuant to which, the Company received an upfrontnon-refundable fee of $15.6 million (the “Collaboration R&D Payment”), which was initially recorded as deferred revenue, to provide the Company with research and development funds to conduct certain clinical trials related to sofpironium bromide. These clinical trials have a benefit to Kaken and have the characteristics of a vendor and customer relationship. The Company has accounted for these under the provisions of Topic 606. This Collaboration R&D Payment will be initially recognized using an input method over the average estimated performance period of 1.45 years in proportion to the cost incurred. Upon receipt of the Collaboration R&D Payment, on May 31, 2018, a milestone payment originally due upon the first commercial sale in Japan was removed from the Collaboration Agreement and all future royalties to the Company under the Collaboration Agreement were reduced 150 basis points.

Consequently, during the three and six months ended June 30, 2019, the Company recognized revenue of $2.6 million and $6.1 million, respectively related to the Collaboration R&D Payment. As of June 30, 2019, the Company has a deferred revenue balance related to the Collaboration R&D Payment of $3.6 million, of which $3.0 million, is recorded in deferred revenue, current portion on the accompanying balance sheets.

Milestones

F-13

included in the transaction price using the most likely amount method. If it is probable that a significant revenue reversal would not occur, the associated milestone value is included in the transaction price. Milestone payments that are not within our or our collaboration partner’s control, such as regulatory approvals, are generally not considered probable of being achieved until those approvals are received. The transaction price is then allocated to each performance obligation on a relative stand-alone selling price basis, for which the Company recognizes revenue as or when the performance obligations under the contract are satisfied. At the end of each subsequent reporting period, the Companyre-evaluates the probability of achievement of such milestones and any related constraint, and if necessary, adjust the Company’s estimate of the overall transaction price. Any such adjustments are recorded on a cumulativecatch-up basis, which would affect license, collaboration or other revenues and earnings in the period of adjustment.

In October 2017, the Company entered into an amendment to the Collaboration Agreement, pursuant to which, the Company granted Kaken a prepayment option (the “Kaken Option”) on 50% of the Initiation of Phase III milestone (the “Phase III milestone”). The Kaken Option was exercisable by Kaken within 25 business days of receipt of theBBI-4000-CL-203 study topline results. In December 2017, Kaken exercised the Kaken Option and paid the Company $5.0 million (the “Kaken Option Payment”). Upon receipt of thenon-refundable Kaken Option Payment, the Company provided Kaken the right to negotiate an exclusive license to develop, manufacture and commercialize each of the Company’s other product candidates in Japan (“ROFN Agreement”). Under the ROFN Agreement, following the completion of any Initial Proof of Concept Clinical Trial (“Initial POC”) for the Company’s other product candidates, the Company must provide Kaken with certain information relating to the results of the clinical trial (“Initial POC Package”). The ROFN Agreement is exercisable by Kaken within 30 days of receipt of the Initial POC Package. In December 2017, the Company recognized collaboration revenue related to the Collaboration Agreement of $5.0 million, in connection with the Kaken Option. Additionally, the Company recognized sublicensing costs of $1.0 million, which are included in general and administrative expenses.

The Collaboration Agreement was further amended in March 2018 to accelerate payment of the Phase III milestone. The Phase III milestone was modified to be due upon the successful completion of the End of Phase 2 Meeting with the PMDA by Kaken on March 8, 2018, as determined by Kaken in its reasonable discretion (the “Third Milestone”). In March 2018, Kaken triggered the Third Milestone and paid the Company $5.0 million (the “Third Milestone Payment”). Upon receipt of thenon-refundable Third Milestone Payment, the ROFN Agreement was amended (the “Amended ROFN Agreement”) to grant an additional option to exercise upon completion of a Subsequent Clinical Trial (first clinical trial after the Initial POC) for the Company’s other product candidates. The Company has determined that the ROFN Agreement is not a material right and has not allocated transaction price to this provision. As of June 30, 2019, Kaken has not exercised the Amended ROFN Agreement. In March 2018, the Company recognized collaboration revenue related to the Collaboration Agreement of $5.0 million in connection with the Third Milestone. Additionally, the Company recognized sublicensing costs of $1.0 million, which are included in general and administrative expenses.

Royalties

For arrangements that include sales-based royalties, including milestone payments based on the level of sales, and for which the license is deemed to be the predominant item to which the royalties relate, the Company recognized revenue at the later of (i) when the related sales occur, or (ii) when the performance obligation to which some or all of the royalty has been allocated has been satisfied (or partially satisfied). To date, the Company has not recognized any royalty revenue from any collaborative arrangement.

Under collaborative arrangements, the Company has been reimbursed for a portion of the Company’s research and development expenses, including costs of drug supplies. When the research and development services are performed under a reimbursement or cost sharing model with a collaboration partner, the Company records these reimbursements as a reduction of research and development expense in the Company’s statements of operations.

Net Income (Loss) per Common Share

Basic and diluted net income (loss) per common share is computed by dividing net income (loss) attributable to common stockholders by the weighted average number of common shares outstanding. When the effects are notanti-dilutive, diluted earnings per share is computed by dividing the Company’s net earnings by the weighted average number of common shares outstanding and the impact of all dilutive potential common shares.

Diluted earnings per share gives effect to all dilutive potential common shares outstanding during the period, including stock options and warrants, using the treasury stock method, and redeemable convertible preferred stock, using theif-converted method. In computing diluted earnings per share, the average stock price for the period is used in determining the number of shares assumed to be purchased from the exercise of stock options or warrants. Potentially dilutive common share equivalents are excluded from the diluted earnings per share computation in net loss periods, since their effect would beanti-dilutive.

The following table sets forth the potential common shares excluded from the calculation of net loss per common share, because their inclusion would beanti-dilutive:

RECENT ACCOUNTING PRONOUNCEMENTS

In August 2018, the FASB issued ASU2018-13, Fair Value Measurement Disclosure Framework—Changes to the Disclosure Requirements for Fair Value Measurement (“ASU2018-13”), which amends certain disclosure requirements over Level 1, Level 2 and Level 3 fair value measurements. ASU2018-13 is effective for fiscal years beginning after December 15, 2019 and interim periods within those fiscal years. Early adoption is permitted. The Company is currently evaluating the impact of adopting ASU2018-13, but does not anticipate it will have a material impact on its disclosures.

In February 2016, the FASB issued ASUNo. 2016-02, “Leases (Topic 842)” (“ASU2016-02”). ASU2016-02 is aimed at making leasing activities more transparent and comparable, and requires substantially all leases be recognized by lessees on their balance sheets as aright-of-use asset and corresponding lease liability, including leases currently accounted for as operating leases. The Company adopted ASU2016-02 on January 1, 2019 using the modified retrospective approach. The adoption did not have a material impact on the Company’s statements of operations. The new standard has required the Company to establish liabilities and correspondingright-of-use assets on its condensed balance sheet for operating leases of $0.2 million that existed as of the January 1, 2019 adoption date. The impact on the Condensed Balance Sheets as of January 1, 2019 was as follows:

NOTE 5.

CONVERTIBLE PROMISSORY NOTES

In March 2019, the Company initiated a convertible promissory notes offering pursuant to which the Company issued unsecured convertible promissory notes (the “Prom Notes”), bearing interest at 12.00% and maturing in one year and can be converted into shares of SeriesC-1 redeemable convertible preferred stock or the most senior preferred equity outstanding at the time of conversion at the option of the holder at a conversion price of $10.72 per share. In addition, the Prom Notes will automatically convert if a qualified financing of at least $15.0 million occurs before maturity and such mandatory conversion price will equal 80% of the effective price per share paid in the qualified financing, but not to exceed $13.40 per share. As of June 30, 2019, the Company had raised an aggregate principal amount of $5.1 million in Prom Notes.

The Prom Notes also provide for the issuance of warrants at 50% coverage, to acquire a minimum of 239,131 shares of common stock. The warrants are exercisable for a term of five years at an exercise price of $14.74 or 10% premium to the effective price per share paid in the qualified financing. The Company evaluated the various financial instruments under ASC 480 and ASC 815 and determined the warrants required fair value accounting. The fair value of the warrants was recorded as a warrant liability upon issuance. The fair value of the warrants on the date of issuance of $1.0 million was determined by a third-party valuation firm. The fair value of the warrants was recorded as a debt discount upon issuance and will be amortized to interest expense over the term of the Prom Notes based on the effective interest method.

The Company analyzed the conversion feature of the agreement for derivative accounting consideration under ASC 815 and determined that the embedded conversion features should be classified as a derivative because the exercise price of the Prom Notes are subject to a variable conversion rate. The Company has determined that the variable conversion feature is a redemption feature that is not clearly and closely related to the Prom Notes and is therefore required to be bifurcated. In accordance with AC 815, the Company has bifurcated the conversion feature of the Prom Notes and recorded a derivative liability.

The embedded derivative for the Prom Notes is carried on the Company’s balance sheet at fair value. The derivative liability ismarked-to-market each measurement period and any change in fair value is recorded as a component of the statements of operations. The fair value of the derivative liability on the date of issuance of $1.0 million was determined by a third-party valuation firm. The fair value of the conversion feature was recorded as a debt discount upon issuance and will be amortized to interest expense over the term of the Prom Notes based on the effective interest method.

The Company then evaluated the conversion option to discern whether a beneficial conversion feature existed based upon comparing the effective exercise price of the convertible notes to the fair value of the shares they are convertible into. The Company concluded no beneficial conversion feature existed. During the three and six months ended June 30, 2019 recognized $0.5 million of interest expense, including $0.4 million of accretion of discounts using an effective interest rate of 12.00%.

As of June 30, 2019, there were unaccreted debt discounts of $1.6 million, which were recorded as a direct deduction from convertible promissory notes on the accompanying balance sheets.

NOTE 6.

NOTE PAYABLE

Note Payable

On February 18, 2016, the Company entered into a loan and security agreement (the “Loan Agreement”) with Hercules Capital, Inc. (the “Lender”) under which the Company borrowed $7.5 million upon the execution of the Loan Agreement on February 18, 2016. The interest rate applicable to each tranche is variable based upon the greater of either (i) 9.2% and (ii) the sum of (a) the Prime Rate as reported in The Wall Street Journal minus 3.5%, plus (b) 9.2%; notwithstanding the above, such rate shall not exceed the permissible rates of interest on commercial loans under the laws of the State of California. Payments under the Loan Agreement were interest only until June 1, 2017, followed by equal monthly payments of principal and interest through the scheduled maturity date on September 1, 2019.

The Company’s obligations under the Loan Agreement are secured by a first priority security interest in substantially all of the Company’s assets, other than its intellectual property. The Company also has agreed not to pledge or otherwise encumber its intellectual property assets, except that the Company may grantnon-exclusive licenses of intellectual property entered into in the ordinary course of business, and licenses approved by the Company’s Board of Directors that may be exclusive in respects other than territory and may be exclusive as to territory as to discrete geographical areas outside of the United States.

The Company has paid the Lender a facility fee of $150,000 in connection with the Loan Agreement. In addition, if the Company repays all or a portion of the loan prior to maturity, it will pay the Lender a prepayment penalty fee, based on a percentage of the then outstanding principal balance, equal to 3% if the prepayment occurs prior to February 19, 2017, 2% if the prepayment occurs prior to February 19, 2018, or 1% if the prepayment occurs thereafter. In addition, the Company is required to make an end of term payment of 4.5% of the sum of (i) term loan advances, plus (ii) 50% of the aggregate unfunded term loan commitments.

The Loan Agreement was amended in December 2017 (as further amended, “Loan Agreement”) to provide for an additional three-month interest only period ending on March 1, 2018, at which time the outstanding loan balance would continue to be paid in equal monthly installments of principal and interest. Pursuant to the Loan Agreement, the end of term payment was increased by $30,500.

The Loan Agreement was further amended in March 2018 to provide for an additionaltwo-month interest only period ending on June 1, 2018, at which time the outstanding loan balance would continue to be paid in equal monthly installments of principal and interest. Pursuant to the Loan Agreement, a facility fee of $25,000 was paid upon execution and the end of term payment was increased by $25,000.

The Loan Agreement was again amended in July 2018 to provide for an additional three-month interest only period ending on October 1, 2018, at which time the outstanding loan balance would continue to be paid in equal monthly installments of principal and interest. Pursuant to the Loan Agreement, a facility fee of $25,000 was paid upon execution and the end of term payment was increased by $25,000.

The Loan Agreement includes customary affirmative and restrictive covenants, and also includes customary events of default, including payment defaults, breaches of covenants following any applicable cure period, a material impairment in the perfection or priority of the Lender’s security interest or in the value of the collateral, and a material impairment of the prospect of repayment of the loans. Upon the occurrence of an event of default and following any applicable cure periods, a default interest rate of an additional 4% may be applied to the outstanding loan balances, and the Lender may declare all outstanding obligations immediately due and payable and take such other actions as set forth in the Loan Agreement.

F-17

Under the Loan Agreement, the Company grants the Lender the right to participate in and/or designate one or more of its affiliates to participate in any subsequent financing in an amount up to $1.0 million on the same terms, conditions and pricing afforded to other participating in such subsequent financing.

In connection with the Loan Agreement, the Company issued warrants to the Lender, which are exercisable for 26,087 shares of Series C redeemable convertible preferred stock at a per share exercise price of $11.50 (the “Warrants”). The Warrants will terminate, if not earlier exercised, on February 18, 2026. The fair value of the warrants was recorded as a redeemable convertible preferred stock warrant liability upon issuance. The fair value of the warrants on the date of issuance of $0.3 million was determined using the Black-Scholes option-pricing model. The fair value of the warrants was recorded as a debt discount upon issuance and will be amortized to interest expense over the term of the loan based on the effective interest method.

As of June 30, 2019, there were unaccreted debt discounts and issuance costs of $0.1 million, which were recorded as a direct deduction from note payable on the accompanying balance sheets.

COMMITMENTS AND CONTINGENCIES

Operating Leases

In August 2016, the Company entered into a five-year lease for office space in Boulder, Colorado that expires on October 31, 2021 (the “Boulder Lease”) subject to the Company’s option to renew the Boulder Lease for two additional terms of three years each. Pursuant to the Boulder Lease, the Company leased 3,038 square feet of space in a multi-suite building. Rent payments under the Boulder Lease included base rent of $4,430 per month during the first year of the Boulder Lease with an annual increase of 3.5%, and additional monthly fees to cover the Company’s share of certain facility expenses, including utilities, property taxes, insurance and maintenance, which were $2,160 per month during the first year of the Boulder Lease.

The Company recognized aright-of-use asset and corresponding lease liability on January 1, 2019, by calculating the present value of lease payments, discounted at 12.0%, the Company’s estimated incremental borrowing rate, over the 2.8 years expected remaining term. As the Company’s lease does not provide an implicit rate, the Company estimated the incremental borrowing rate based on industry peers. Industry peers consist of several public companies in the biotechnology industry with comparable characteristics, including clinical trials progress

and therapeutic indications. Amortization of the operating leaseright-of-use asset for the Boulder Lease amounted to $17,000 and $33,000 for the three and six months ended June 30, 2019, respectively, and was included in operating expense. As of June 30, 2019, the remaining lease term was 2.3 years.

The terms of the Boulder Lease provide for rental payments on a monthly basis on a graduated scale. The Company recognizes rent expense on astraight-line basis over the lease period. Lease expense for the three and six months ended June 30, 2019 and 2018 was $0.1 million.

NOTE 8.

REDEEMABLE CONVERTIBLE PREFERRED STOCK

As of June 30, 2019 and December 31, 2018, the Company had authorized 4,446,228 and 4,182,943 shares of redeemable convertible preferred stock, par value of $0.0001, of which 1,162,505 are designated Series A redeemable convertible preferred stock (“Preferred Stock A”), 882,216 are designated Series B redeemable convertible preferred stock (“Preferred Stock B”), 869,565 are designated Series C redeemable convertible preferred stock (“Preferred Stock C”) and 1,531,942 are designatedSeries C-1 redeemable convertible preferred stock (“Preferred StockC-1”)

In connection with the issuance of the Preferred Stock A, B, C andC-1 (the “Preferred Stock”), the Company incurred approximately $0.5 million of issuance costs. The unaccreted discount as of June 30, 2019 and December 31, 2018 amounted to approximately $0.1 million.

The rights, preferences and privileges of the Preferred Stock are as follows:

Dividends

F-19

In May 2019, the Company amended dividend rights that have accrued through May 31, 2019 whereby the accrued dividends payable to the holders of the Company’s outstanding preferred stock will settle with shares of the Company’s common stock in lieu of cash. Dividends will not continue to accrue after May 31, 2019.

Accrued dividends at June 30, 2019 amounted to $6.0 million ($5.13 per share), $3.3 million ($4.02 per share), $3.1 million ($4.15 per share), and $2.0 million ($2.22 per share) on Preferred Stock A, B, C andC-1, respectively. Accrued dividends at December 31, 2018 amounted to $5.7 million ($4.90 per share), $3.1 million ($3.68 per share), $2.9 million ($3.86 per share), and $1.7 million ($1.92 per share) on Preferred Stock A, B, C andC-1, respectively. Accrued dividends are included as a component of redeemable convertible preferred stock in the accompanying balance sheets.

Liquidation Preference

Preferred Stock carries certain liquidation rights upon the liquidation, dissolution, or winding up of the Company, whether voluntary or involuntary (including a change in control), whereas before any distribution or payment shall be made to the holders of any common stock, the holders of the Preferred Stock shall be entitled to be paid an amount equal to the original purchase price plus any accrued but unpaid dividends out of the assets of the Company legally available for distribution for each share. If the assets of the Company available for distribution upon liquidation are not sufficient to pay the preferred stock preference amount, the assets will be distributed ratably among the holders of the Preferred Stock in proportion to the full amount of the preference amount such holder is otherwise entitled to receive.

Any proceeds remaining after the distribution of the preference amount shall be distributed pro rata to the holders of the Preferred Stock (onas-if-converted to Common Stock basis) and the holders of Common Stock.

Preferred Stock may be converted into common stock at the initial conversion ratio of 1:1, which ratio shall be altered in accordance with stock dividends, splits, combinations and other similar events, including the sale of additional shares of common or preferred stock at an effective price per common share lower than the conversion price then in effect. Each share of the Preferred Stock will automatically convert into shares of common stock, at the applicable conversion ratio of each series of redeemable convertible preferred stock then in effect, upon (i) a qualified public offering with net proceeds of not less than $30 million and a price of not less than $57.50 per share, subject to appropriate adjustment for any stock dividend, stock split, combination or other similar recapitalization, or (ii) the date specified by written consent or agreement of the holders of at leasttwo-thirds of the then outstanding shares of Preferred Stock voting together as a single class on anas-if-converted to Common Stock basis.

Redemption

At any time after July 16, 2021, the holders of the Company’s Preferred Stock will have the right to require the Company to redeem all or a portion of their shares for cash at a redemption price equal to the greater of: (i) the purchase price of such shares plus all accrued and unpaid dividends thereon, or the (ii) fair market value of the shares.

Voting Rights

The holders of Preferred Stock are entitled to vote, together with the holders of common stock, on all matters submitted to stockholders for a vote. Holders of Preferred Stock have the right to vote the number of shares equal to the number of shares of common stock into which such Preferred Stock could convert on the record date for determination of stockholders entitled to vote. The holders of the majority of Preferred Stock, voting separately as a single class, are entitled to elect two directors of the Company.

Report of Independent Registered Public Accounting Firm

To the Shareholders and the Board of Directors of Brickell Biotech, Inc.

Opinion on the Financial Statements

We have audited the accompanying balance sheets of Brickell Biotech, Inc. (the Company) as of December 31, 2018 and 2017, the related statements of operations, redeemable convertible preferred stock and stockholders’ deficit and cash flows for the years then ended, and the related notes (collectively referred to as the “financial statements”). In our opinion, the financial statements present fairly, in all material respects, the financial position of the Company at December 31, 2018 and 2017, and the results of its operations and its cash flows for the years then ended, in conformity with U.S. generally accepted accounting principles.

The Company’s Ability to Continue as a Going Concern

The accompanying financial statements have been prepared assuming that the Company will continue as a going concern. As discussed in Note 1 to the financial statements, the Company has suffered recurring losses from operations and has stated that substantial doubt exists about the Company’s ability to continue as a going concern. Management’s evaluation of the events and conditions and management’s plans regarding these matters are also described in Note 1. The financial statements do not include any adjustments that might result from the outcome of this uncertainty.

Basis for Opinion

These financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on the Company’s financial statements based on our audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (PCAOB) and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement, whether due to error or fraud. The Company is not required to have, nor were we engaged to perform, an audit of its internal control over financial reporting. As part of our audits we are required to obtain an understanding of internal control over financial reporting but not for the purpose of expressing an opinion on the effectiveness of the Company’s internal control over financial reporting. Accordingly, we express no such opinion.

Our audits included performing procedures to assess the risks of material misstatement of the financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statements. We believe that our audits provide a reasonable basis for our opinion.

NOTES TO FINANCIAL STATEMENTS

NOTE 1.

ORGANIZATION AND NATURE OF OPERATIONS

Brickell Biotech, Inc. (the “Company”) was incorporated in the state of Delaware and commenced activities on September 17, 2009. The Company is aclinical-stage pharmaceutical company focused on the development of innovative and differentiated therapeutics for the treatment of skin diseases. Its current pipeline consists of new molecular entities targeting the treatment of the following indications: hyperhidrosis, allergic contact dermatitis, androgenic alopecia, cutaneoust-cell lymphoma and psoriasis. The Company’s lead product candidate, sofpironium bromide, for the topical treatment of axillary hyperhidrosis (underarm sweating beyond what is needed for normal body temperature regulation), demonstrated positive results in a confirmatory Phase 2b study in the fourth quarter of 2017. Based upon these results, along with the completion of the Company’send-of-Phase 2 meeting with the U.S. Food and Drug Administration (“FDA”) in the first quarter of 2018, the Company expects to initiate its pivotal Phase 3 clinical trials in the U.S. and Canada in the first half of 2019. The Company is headquartered in Boulder, Colorado.

Liquidity and Capital Resources

The accompanying financial statements have been prepared assuming that the Company will continue as a going concern, which contemplates the realization of assets and the settlement of liabilities and commitments in the normal course of business. The financial statements do not reflect any adjustments relating to the recoverability and reclassification of assets and liabilities that might be necessary if the Company is unable to continue as a going concern. The Company has incurred significant operating losses and has an accumulated deficit as a result of ongoing efforts to develop product candidates, including conducting preclinical and clinical trials and providing general and administrative support for these operations. For the year ended December 31, 2018, the Company had a net loss of $9.2 million and net cash provided by operating activities of $4.0 million. As of December 31, 2018, the Company had cash and cash equivalents of $8.1 million and an accumulated deficit of $71.6 million.

The Company expects to continue to incur additional substantial losses in the foreseeable future as a result of the Company’s research and development activities. The Company plans to finance operations through equity or debt financing arrangements, and/orthird-party collaboration funding. Additional funding will be required in the future to maintain its present and proposed research activities. There can be no assurance that additional equity or debt financing will be available on acceptable terms, if at all. If the Company is unable to raise additional funding to meet its working capital needs in the future, it will be forced to delay or reduce the scope of its research programs and/or limit or cease its operations. These factors raise substantial doubt about the Company’s ability to continue as a going concern for a period of twelve months subsequent to the issuance of these financial statements.

NOTE 2.

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Basis of Presentation

The accompanying financial statements are presented in U.S. dollars and have been prepared in accordance with accounting principles generally accepted in the United States of America (“US GAAP”).

Use of Estimates in the Preparation of Financial Statements

The preparation of financial statements, in conformity with US GAAP, requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and

F-27

liabilities as of the balance sheet dates and the reported amounts of revenues and expenses for the periods presented. On an ongoing basis, management evaluates its estimates, including those related to revenue recognition, accrued research and development expenses, intangible assets, other long-lived assets, redeemable convertible preferred stock, warrants, stock-based compensation, and the valuation of deferred tax assets. The Company bases its estimates on its historical experience and also on assumptions that it believes are reasonable; however, actual results could significantly differ from those estimates.

Risks and Uncertainties

The Company expects to incur substantial operating losses for the next several years and will need to obtain additional financing in order to complete clinical studies and launch and commercialize any product candidates for which it receives regulatory approval. There can be no assurance that such financing will be available or will be at terms acceptable by the Company.

Cash and Cash Equivalents

The Company considers all highly liquid debt instruments with an original maturity of three months or less from date of purchase to be cash equivalents. Cash equivalents, which are stated at cost, consist primarily of amounts held inshort-term money market accounts with highly rated financial institutions.

Concentrations of Credit Risk

Financial instruments that potentially subject the Company to concentrations of credit risk consist principally of cash and cash equivalents. The Company maintains cash balances in several accounts with one financial institution which, from time to time, are in excess of federally insured limits.

Property and Equipment

Property and equipment is stated at cost, less accumulated depreciation. Expenditures for major betterments and additions are charged to the asset accounts, while replacements, maintenance and repairs, which do not improve or extend the lives of the respective assets, are charged to expense as incurred. Depreciation is computed using thestraight-line method over the estimated useful lives of the assets, generally between three and five years. Depreciation expense amounted to approximately $49,000 and $48,000 for the years ended December 31, 2018 and 2017, respectively. Accumulated depreciation amounted to approximately $146,000 and $97,000 as of December 31, 2018 and 2017, respectively.

Impairment ofLong-Lived Assets

The Company assesses changes in the performance of its product candidates in relation to its expectations, and industry, economic and regulatory conditions and makes assumptions regarding estimated future cash flows in evaluating the value of its property and equipment, andin-process research and development (“IPR&D”).

F-28

The Company periodically evaluateslong-lived assets for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. If the sum of the expected future undiscounted cash flows is less than the carrying amount of the asset, an impairment loss is recognized to the extent the carrying amount of the impaired asset exceeds its fair value.

IPR&D represents the fair value assigned to incomplete research projects that the Company acquires in business acquisitions, which, at the time of acquisition, have not reached technological feasibility. Amounts capitalized and accounted for as indefinite-lived intangible assets are subject to impairment testing until completion or abandonment of the project. The Company tests IPR&D for impairment at least annually, or more frequently, if impairment indicators exist, by first assessing qualitative factors to determine whether it is more likely than not that the fair value of the IPR&D intangible asset is less than its carrying amount. If the Company concludes it is more likely than not that the fair value is less than the carrying amount, a quantitative test that compares the fair value of the IPR&D intangible asset with its carrying value is performed. If the Company discontinues or abandons a program related to IPR&D and determines that there are no other indicators of value, the Company will impair the entire amount of the related intangible asset. There were no impairments of IPR&D during the years ended December 31, 2018 and 2017.

Fair Value Measurements

The hierarchy is summarized in the three broad levels listed below.

Level 1—quoted prices in active markets for identical assets and liabilities

Level 2—other significant observable inputs (including quoted prices for similar assets and liabilities, interest rates, credit risk, etc.)

Level 3—significant unobservable inputs (including the Company’s own assumptions in determining the fair value of assets and liabilities)

Fair Value of Financial Instruments

The following methods and assumptions were used by the Company in estimating the fair values of each class of financial instrument disclosed herein:

F-30

The fair value of the outstanding convertible preferred stock warrants was remeasured as of December 31, 2018 using the Black-Scholes option-pricing model with the following assumptions: contractual term of 7.1 years, expected volatility of 30.0%, risk-free rate of 2.59%, and expected dividend yield of 0%.

Fair Value of Redeemable Convertible Preferred Stock. The fair value of the shares of the convertible preferred stock underlying the preferred stock warrants has historically been determined by a third-party valuation firm. Because there has been no public market for the Company’s convertible preferred stock, the third-party valuation firm has determined fair value of the convertible preferred stock at each balance sheet date by considering a number of objective and subjective factors, including valuation of comparable companies, sales of convertible preferred stock to unrelated third parties, operating and financial performance, the lack of liquidity of capital stock, and general and industry specific economic outlook, among other factors.

Remaining Term. The Company derived the expected term based on the time from the balance sheet date until the preferred stock warrant’s expiration date.

Risk-Free Interest Rate. The risk-free interest rate is based on U.S. Treasuryzero-coupon issues with remaining terms similar to the expected term of the warrants.

The following table sets forth a summary of the changes in the fair value of the Company’s Level 3 financial instruments as follows (in thousands):


	Redeemable Convertible Preferred Stock Warrant Liability			Contingent Consideration Liabilities
Fair value as of December 31, 2016	$	360		$	193
Change in fair value		126			(45	)

Fair value as of December 31, 2017		486			148
Change in fair value		(244	)		(3	)

Fair value as of December 31, 2018	$	242		$	145

F-31

Redeemable Convertible Preferred Stock

Redeemable convertible preferred stock is classified as a mezzanine instrument outside of the Company’s capital accounts. Accretion of redeemable convertible preferred stock includes the greater of an adjustment to fair market value or the accrual of dividends on and accretion of issuance costs of the Company’s redeemable convertible preferred stock. The carrying values of the redeemable convertible preferred stock are increased by periodic accretion to their respective redemption values, using the effective interest method, from the date of issuance to the earliest date the holders can demand redemption. These increases are recorded as charges against additionalpaid-in capital balance until the additionalpaid-in capital balance is reduced to zero. At that time, additional accretion adjustments are recorded as additions to accumulated deficit.

Preferred stock issuance costs represent costs related to the Company issuing redeemable convertible preferred stock. These amounts are included as a reduction of redeemable convertible preferred stock and are amortized over the estimated redemption period. Amortization of preferred stock issuance costs amounted to approximately $40,000 and $28,000 for the years ended December 31, 2018 and 2017, respectively.

Redeemable Convertible Preferred Stock Warrants

Revenue Recognition

Effective January 1, 2018, the Company adopted Accounting Standards Update (“ASU”)2018-18, Collaborative Arrangements: Clarifying the Interaction Between Topic 808 and Topic 606 (“Topic 808” or “ASU2018-18”) using the retrospective method and ASU2014-09, Revenue from Contracts with Customers (Topic 606) (“Topic 606” or “ASU2014-09”) using the modified retrospective method which consisted of applying and recognizing the cumulative effect of Topic 606 at the date of initial application. Topic 606 supersedes the revenue recognition requirements in Accounting Standards Codification (“ASC”) Topic 605, Revenue Recognition (“Topic 605”), including most industry-specific revenue recognition guidance throughout the Industry Topics of the ASC. All periods prior to the adoption date of Topic 606 have not been restated to reflect the impact of the adoption of Topic 606, but continue to be accounted for and presented under Topic 605.

To date, the Company’s drug candidates have not been approved for sale by the FDA and the Company has not generated or recognized any revenue from the sale of products.

F-32

Collaboration arrangement subsequent to adoption of Topic 606

The Company evaluates collaboration arrangements to determine whether units of account within the collaboration arrangement exhibit the characteristics of a vendor and customer relationship. The Company determined that the licenses transferred to Kaken in exchange for the upfront fees were representative of this type of a relationship. If a license to our intellectual property is determined to be distinct from the other performance obligations identified in the arrangement, the Company recognizes revenues fromnon-refundable, upfront fees allocated to the license when the license is transferred to the licensee and the licensee is able to use and benefit from the license. For licenses that are bundled with other performance obligations, the Company utilizes judgment to assess the nature of the combined performance obligation to determine whether the combined performance obligation is satisfied over time or at a point in time and, if over time, the appropriate method of measuring progress for purposes of recognizing revenue. The Company evaluates the measure of progress each reporting period and, if necessary, adjust the measure of performance and related revenue recognition on a prospective basis.

F-33

2018, the Company does not have a deferred revenue or deferred sublicensing costs balance related to the upfront fee on the balance sheet.

In May 2018, the Company entered into an amendment to the Collaboration Agreement (as further amended, “Collaboration Agreement”), pursuant to which, the Company received an upfrontnon-refundable fee of $15.6 million (the “Collaboration R&D Payment”), which was initially recorded as deferred revenue, to provide the Company with research and development funds to conduct certain clinical trials. These clinical trials have a benefit to Kaken and have the characteristics of a vendor and customer relationship. The Company has accounted for these under the provisions of Topic 606. This Collaboration R&D Payment will be initially recognized using an input method over the average estimated performance period of 1.45 years in proportion to the cost incurred. Upon receipt of the Collaboration R&D Payment, on May 31, 2018, a milestone payment originally due upon the first commercial sale in Japan was removed from the Collaboration Agreement and all future royalties to the Company under the Collaboration Agreement were reduced 150 basis points.

Consequently, during the year ended December 31, 2018, the Company recognized revenue of $5.9 million related to the Collaboration R&D Payment. As of December 31, 2018, the Company has a deferred revenue balance related to the Collaboration R&D Payment of $9.7 million, of which $8.1 million, is recorded in deferred revenue, current portion on the accompanying balance sheets.

Milestones

At the inception of each arrangement that includes milestone payments (variable consideration), the Company evaluates whether the milestones are considered probable of being reached and estimates the amount to be included in the transaction price using the most likely amount method. If it is probable that a significant revenue reversal would not occur, the associated milestone value is included in the transaction price. Milestone payments that are not within our or our collaboration partner’s control, such as regulatory approvals, are generally not considered probable of being achieved until those approvals are received. The transaction price is then allocated to each performance obligation on a relative stand-alone selling price basis, for which the Company recognizes revenue as or when the performance obligations under the contract are satisfied. At the end of each subsequent reporting period, the Companyre-evaluates the probability of achievement of such milestones and any related constraint, and if necessary, adjust the Company’s estimate of the overall transaction price. Any such adjustments are recorded on a cumulativecatch-up basis, which would affect license, collaboration or other revenues and earnings in the period of adjustment.

“Third Milestone”). In March 2018, Kaken triggered the Third Milestone and paid the Company $5.0 million (the “Third Milestone Payment”). Upon receipt of thenon-refundable Third Milestone Payment, the ROFN Agreement was amended (the “Amended ROFN Agreement”) to grant an additional option to exercise upon completion of a Subsequent Clinical Trial (first clinical trial after the Initial POC) for the Company’s other product candidates. The Company has determined that the ROFN Agreement is not a material right and has not allocated transaction price to this provision. As of December 31, 2018, Kaken has not exercised the Amended ROFN Agreement. In March 2018, the Company recognized collaboration revenue related to the Collaboration Agreement of $5.0 million in connection with the Third Milestone. Additionally, the Company recognized sublicensing costs of $1.0 million, which are included in general and administrative expenses.

Royalties

Revenue recognition prior to adoption of Topic 606

Prior to the adoption of Topic 606, the Company was initially recorded the $11.0 million upfront fee as deferred revenue. This upfront fee, along with the corresponding sublicensing fees, was initially recognized over the estimated period during which the research and development plan would be conducted. Consequently, during the years ended December 31, 2017 and 2016, the Company recognized revenue of $2.6 million and $2.9 million, respectively. As of December 31, 2017 and 2016, the Company has a deferred revenue balance related to the upfront fee of $3.4 million and $6.0 million, respectively, of which $1.7 million and $2.9 million, respectively, is recorded in deferred revenue, current portion on the accompanying balance sheets.

Additionally, during the years ended December 31, 2017 and 2016, the Company recognized sublicensing costs of $0.5 million and $0.6 million, respectively, which are included in general and administrative expenses in the accompanying statements of operations. As of December 31, 2017 and 2016, the Company has $0.7 million and $1.2 million, respectively, in deferred sublicensing costs related to the upfront fee, of which $0.3 million and $0.6 million, respectively, is recorded in deferred sublicensing costs, current portion on the accompanying balance sheets.

Contingent Consideration

Contingent consideration represents future amounts the Company may be required to pay in conjunction with business combinations. The ultimate amount of future payments is based on specified future criteria, such as the achievement of certain future development and regulatory milestones. The Company estimates the fair value of the contingent consideration related to the achievement of future development and regulatory milestones by assigning an achievement probability to each potential milestone and discounting the associated cash payment to its present value using a risk-adjusted rate of return. The Company evaluates its estimates of the fair value of contingent consideration on a periodic basis. Any changes in the fair value of contingent consideration are recorded in the accompanying statements of operations as general and administrative expenses. The total estimated fair value of contingent consideration was approximately $145,000 and $148,000 at December 31, 2018 and 2017, respectively.

F-35

Research and Development

Research and development costs are charged to expense when incurred and consist of costs incurred for independent and collaborative research and development activities. The major components of research and development costs include formulation development, clinical studies, clinical manufacturing costs, salaries and employee benefits, toxicology studies, allocations of various overhead and occupancy costs, and licensing fees and milestone payments incurred under license agreements. Research costs typically consist of applied research, preclinical, and toxicology work. Pharmaceutical manufacturing development costs consist of product formulation, chemical analysis, and the transfer andscale-up of manufacturing at contract manufacturers.

Accrued Research and Development Expenses

The Company records accruals for estimated costs of research, preclinical and clinical studies, and manufacturing development, which are a significant component of research and development expenses. A substantial portion of the Company’s ongoing research and development activities is conducted by third-party service providers, including CROs. The Company’s contracts with CROs generally include pass-through fees such as regulatory expenses, investigator fees, travel costs and other miscellaneous costs, including shipping and printing fees. The financial terms of these contracts are subject to negotiations, which vary from contract to contract and may result in payment flows that do not match the periods over which materials or services are provided to the Company under such contracts. The Company accrues the costs incurred under agreements with these third parties based on actual work completed in accordance with the respective agreements. In the event the Company makes advance payments, the payments are recorded as a prepaid asset and recognized as the services are performed. The Company determines the estimated costs through discussions with internal personnel and external service providers as to the progress or stage of completion of the services and the agreed-upon fees to be paid for such services.

The Company makes significant judgments and estimates in determining the accrual balance in each reporting period. As actual costs become known, the Company adjusts its accruals. Although the Company does not expect its estimates to be materially different from amounts actually incurred, the Company understands the status and timing of services performed relative to the actual status and timing of services performed may vary and could result in the Company reporting amounts that are too high or too low in any particular period. The Company’s accrual is dependent, in part, upon the receipt of timely and accurate reporting from CROs and other third-party vendors. To date, there have been no material differences from the Company’s accrued estimated expenses to the actual clinical trial expenses. However, variations in the assumptions used to estimate accruals including, but not limited to the number of patients enrolled, the rate of patient enrollment, and the actual services performed may vary from the Company’s estimates, resulting in adjustments to, clinical trial expense in future periods. Changes in these estimates that result in material changes to the Company’s accruals could materially affect its financial condition and results of operations.

Prepaid expenses and other current assets includes prepaid research and development costs of $95,000 and $12,000 as of December 31, 2018 and 2017, respectively.

Stock-Based Compensation

Stock options granted to employees andnon-employees under the Company’s stock option plan are accounted for by using a fair value based method.Stock-based payments to employees, including grants of employee stock options, are measured based on their fair values at the date of grant, net of forfeitures, and are recorded on a straight-line basis over the requisite employee service period. The fair value ofstock-based payments tonon-employees is estimated at each reporting period, net of forfeitures, until a measurement date is reached, and recorded over the service period on a straight-line basis.

F-36

Net Loss per Common Share

Basic and diluted net loss per common share is computed by dividing net loss attributable to common stockholders by the weighted average number of common shares outstanding. When the effects are notanti-dilutive, diluted earnings per share is computed by dividing the Company’s net earnings by the weighted average number of common shares outstanding and the impact of all dilutive potential common shares.

The following table sets forth the potential common shares excluded from the calculation of net loss per common share, because their inclusion would beanti-dilutive:


	2018		2017
Redeemable convertible preferred stock (as converted into common stock)		3,639,905		3,639,905
Options to purchase common stock		1,090,045		826,225
Warrants to purchase common stock		160,365		160,365
Warrants to purchase redeemable convertible preferred stock (as converted into common stock)		26,087		26,087

		4,916,402		4,652,582

Income Taxes

The Company accounts for income taxes under the liability method, whereby deferred tax assets and liabilities are provided for the future tax consequences attributable to temporary differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases. Deferred tax assets and liabilities are measured using enacted rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled.

Deferred tax assets, net of a valuation allowance, are recorded when management believes it is more likely than not that the tax benefits will be realized. Realization of the deferred tax assets is dependent upon generating sufficient taxable income in the future. The amount of deferred tax asset considered realizable could change in the near term if estimates of future taxable income are modified. The Company assesses its tax positions and determines whether it has any material unrecognized liabilities for uncertain tax positions expected to be taken in a tax return for open tax years (generally a period of three years from the later of each return’s due date or the date filed) that remain subject to examination by the Company’s major tax jurisdictions. Generally, the Company is no longer subject to income tax examinations by major taxing authorities for years before 2014.

The Company assesses its tax positions and determines whether it has any material unrecognized liabilities for uncertain tax positions. The Company records these liabilities to the extent it deems them more likely than not to be incurred. Interest and penalties related to uncertain tax positions, if any, would be classified as a component of income tax expense. The Company believes that it does not have any significant uncertain tax positions requiring recognition or measurement in the accompanying financial statements.

Segment Data

The Company manages its operations as a single segment for the purposes of assessing performance and making operating decisions. The Company’s singular focus is identifying, developing and commercializing innovative and differentiated therapeutics for the treatment of skin diseases. No revenue from sales of product has been generated since inception, and all tangible assets are held in the United States.

RECENT ACCOUNTING PRONOUNCEMENTS

In November 2018, the Financial Accounting Standards Board (“FASB”) issued ASU2018-18. ASU2018-18 clarifies when certain transactions between collaborative arrangement participants should be accounted for under ASC 606 and incorporatesunit-of-account guidance consistent with ASC 606 to aid in this determination. ASU2018-18 is effective for public companies for annual and interim periods beginning after December 15, 2019, with early adoption permitted. ASU2018-18 should generally be applied retrospectively to the date of initial application of Topic 606. The Company adopted this standard as of January 1, 2018 in connection with its adoption of Topic 606.

As noted above, effective January 1, 2018, the Company adopted Topic 606. Since ASU2014-09 was issued, several additional ASUs have been issued and incorporated within Topic 606 to clarify various elements of the guidance. As part of its adoption efforts, the Company completed the assessment of its collaboration and license agreements under Topic 606. The Company adopted Topic 606 in the first quarter of 2018 using the modified retrospective method which consists of applying and recognizing the cumulative effect of Topic 606 at the date of initial application and providing certain additional disclosures as defined per Topic 606. On January 1, 2018, the Company recorded a cumulative adjustment to decrease deferred revenue, deferred sublicensing costs and accumulated deficit by approximately $2.7 million, to reflect the impact of the adoption of Topic 606.

Below is a summary of the affected line items on the balance sheets upon adoption of Topic 606 (in thousands):


Balance Sheet	Balance at December 31, 2017			Adjustments Due to Topic 606			Balance at January 1, 2018
Deferred sublicensing costs, current portion	$	(342	)	$	342		$	—
Deferred sublicensing costs, net of current portion		(342	)		342			—
Deferred revenue, current		1,709			(1,709	)		—
Deferred revenue, net of current portion		1,709			(1,709	)		—
Accumulated deficit	$	(59,936	)		2,734			(57,202	)

As a result of adopting Topic 606 on January 1, 2018 under the modified retrospective method, the Company did not revise the comparative financial statements for the prior years as if Topic 606 had been effective for those periods. Below is disclosure of what the affected line items on the statement of operations would have been in the year ended December 31, 2018 under Topic 605 (in thousands):


	Year Ended December 31, 2018
Statement of Operations	As Reported			Balances Without Adoption Topic 606			Effect of Change
Collaboration revenue	$	10,888			13,186			(2,298	)
General and administrative		(6,379	)		(6,724	)		345

In January 2017, the FASB issued ASU2017-01, “Business Combinations (Topic 805): Clarifying the Definition of a Business” (“ASU2017-01”), which clarifies the definition of a business with the objective of adding guidance to assist entities with evaluating whether transactions should be accounted for as acquisitions (or disposals) of assets or businesses. The amendments of ASU2017-01 are effective for fiscal years beginning after

F-38

December 15, 2017 and interim periods within those fiscal years for public companies and for annual periods beginning after December 15, 2018, and interim periods within annual periods beginning after December 15, 2019 for private companies. The Company adopted this standard as of January 1, 2018, and there was no material impact to the Company’s financial statements as a result of the adoption.

In August 2016, the FASB issued ASU2016-15, “Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments” (“ASU2016-15”), which will make eight targeted changes to how cash receipts and cash payments are presented and classified in the statement of cash flows. ASU2016-15 is effective for fiscal years beginning after December 15, 2017 for public companies and for annual periods beginning after December 15, 2018, and interim periods within annual periods beginning after December 15, 2019 for private companies. ASU2016-15 will require adoption on a retrospective basis. Early adoption is permitted. The Company adopted this standard as of January 1, 2018, and there was no material impact to the Company’s financial statements as a result of the adoption.

In February 2016, the FASB issued ASUNo. 2016-02, “Leases (Topic 842)” (“ASU2016-02”). ASU2016-02 is aimed at making leasing activities more transparent and comparable, and requires substantially all leases be recognized by lessees on their balance sheets as aright-of-use asset and corresponding lease liability, including leases currently accounted for as operating leases. This ASU is effective for fiscal years, and interim periods within those years, beginning after December 15, 2018 for public companies and for annual periods beginning after December 15, 2018, and interim periods within annual periods beginning after December 15, 2019 for private companies. Early adoption is permitted. The Company will adopt ASU2016-02 on January 1, 2019. The Company expects to recognize aright-of-use asset and a lease liability on its balance sheet for the discounted value of future lease payments from the adoption of this ASU. As of December 31, 2018, the Company had aggregate future minimum lease payments of approximately $0.3 million. The Company is currently evaluating the full impact that the adoption of this ASU will have on its financial statements and related disclosures.

INTANGIBLE ASSETS

In January 2015, the Company acquired certain assets and assumed certain liabilities associated with the rights to an IPR&D molecular compound in the Phase I stage of development,BBI-5000, for $100,000 plus up to an aggregate of $13.5 million in payments contingent upon achieving certain future development milestones. The Company intends to developBBI-5000 as a potentialonce-daily oral treatment for patients with moderate to severe atopic dermatitis.

In November 23, 2015, the Company secured the exclusive worldwide rights to a series of novel retinoic acid-related orphan nuclear receptor gamma (“RORy”) inhibitors from Orca Pharmaceuticals (“Orca”) and New York University (“NYU”), for an upfront payment of $105,000 plus up to an aggregate of $3.4 million in payments contingent upon achieving certain future development and sales milestones. The Company intends to developBBI-6000 as a potential topical treatment for patients with psoriasis.

F-39

The Company accounted for both transactions as business combinations. The asset purchase agreements meet the definition of a business pursuant to the guidance prescribed in ASC Topic 805, “Business Combinations”. Accordingly, forBBI-5000 andBBI-6000, the Company capitalized the $321,000 and $120,000 acquisition-date fair values of these intangible assets, respectively. As of all periods presented, these assets are considered to be indefinite-lived and will not be amortized, but will be tested for impairment on an annual basis, as well as between annual tests if changes in circumstances indicate a reduction in the fair value of the IPR&D projects below their respective carrying amounts. If and when development is complete, the associated assets would be deemed finite-lived and would then be amortized based on their respective estimated useful lives.

ForBBI-5000 andBBI-6000 the Company has estimated the fair value of the contingent consideration to be $221,000 and $15,000, respectively, as of the acquisition date by assigning an achievement probability to each potential milestone and discounting the associated cash payment to its present value using a risk-adjusted rate of return. The Company evaluates its estimates of the fair value of contingent consideration on a periodic basis. Any changes in the fair value of contingent consideration are recorded as general and administrative expense.

NOTE 6.

INCOME TAXES

During the years ended December 31, 2018 and 2017, the Company recorded no income tax benefits for the net operating losses incurred in each year, due to its uncertainty of realizing a benefit from those items.

A reconciliation of the U.S. federal statutory income tax rate to the Company’s effective income tax rate is as follows:


	2018			2017
Federal statutory income tax rate		21.00	%		34.00	%
State taxes, net of federal benefit		3.71			1.07
Research and development tax credits		8.77			6.15
Permanent differences and other		2.36			(2.14	)
Change in tax rate		1.80			(46.04	)
Change in deferred tax asset valuation allowance		(37.64	)		6.96

Effective income tax rate		0.00	%		0.00	%

At December 31, approximate deferred tax assets (liabilities) resulting from timing differences between financial and tax bases related to the following items:


	2018			2017
Net operating loss carryforwards	$	8,918,000		$	7,967,000
Stock-based compensation		520,000			393,000

	$	—		$	—

As of December 31, 2018, the Company had net operating loss carryforwards for federal income tax reporting purposes of approximately $36.5 million, which begin to expire in 2030, and state net operating loss carryforwards of $30.9 million, which begin to expire in 2030. As of December 31, 2018, the Company also had research and development tax credit carryforwards for federal income tax reporting purposes available of $3.2 million, which begin to expire in 2035.

F-40

On December 22, 2017, the U.S. Tax Cuts and Jobs Acts (“Tax Act”) was signed into law. The Tax Act significantly revised the U.S. corporate income tax regime by, among other changes, lowering the federal corporate tax rate from 34% to 21% effective January 1, 2018. Based on provisions of the Tax Act, the Company remeasured its deferred tax assets and liabilities to reflect the lower statutory tax rate. The Company has recorded a decrease related to deferred tax assets of $5.1 million. However, since the Company established a valuation allowance to offset its deferred tax assets, there is no impact to its effective tax rate, as any changes to deferred taxes would be offset by the valuation allowance.

The Company has evaluated the positive and negative evidence bearing upon its ability to realize the deferred tax assets. Management has considered the Company’s history of cumulative net losses incurred since inception and its lack of commercialization of any products or generation of any revenue from product sales since inception and has concluded that it is more likely than not that the Company will not realize the benefits of the deferred tax assets. Accordingly, a full valuation allowance has been established against the deferred tax assets as of December 31, 2018 and 2017. Management reevaluates the positive and negative evidence at each reporting period. The Company’s valuation allowance increased by approximately $3.5 million and decreased by approximately $0.8 million for the years ended December 31, 2018 and 2017, respectively.

NOTE 11.

STOCK-BASED COMPENSATION

The Company’s 2009 Equity Incentive Plan, as amended and restated (the “2009 Plan”), provides for the Company to sell or issue common stock or restricted common stock, or to grant incentive stock options or nonqualified stock options for the purchase of common stock, to employees, members of the Board of Directors and consultants of the Company. At December 31, 2018, the total shares authorized under the 2009 Plan were 2,872,986 shares. The Board of Directors or a designated Committee of the Board is responsible for the administration of the 2009 Plan and determines the term, exercise price, and vesting terms of each option. Under the terms of existing awards, all stock option grants expire ten years from grant date.

A summary of all stock option activity under the 2009 Plan is presented below:


Outstanding Options	Shares			Weighted Average Exercise Price		Total Intrinsic Value		Weighted Average Remaining Contractual Life (In Years)
Outstanding at December 31, 2017		1,354,166		$	3.91	$	2,511,589		7.74
Granted		775,967			5.68
Exercised		(10,833	)		4.20
Forfeited		(100,625	)		4.39

Outstanding at December 31, 2018		2,018,675			4.56		2,265,118		7.96

Options vested and exercisable at December 31, 2018		1,090,045		$	3.75	$	2,103,832		6.51

Options vested at December 31, 2018 and expected to vest		1,953,675		$	4.53	$	2,253,829		7.91

At December 31, 2018 and 2017, a total of 538,060 shares and 416 shares, respectively, were available for grant under the 2009 Plan. The total estimated grant date fair value of stock options vested during the years ended December 31, 2018 and 2017 was $0.8 million and $0.9 million, respectively. The total intrinsic value of options exercised during the years ended December 31, 2018 and 2017 amounted to $0.1 million.

Total stock-based compensation expense related to stock options granted under the 2009 Plan was allocated as follows:


	Year Ended December 31,
	2018		2017
Research and development	$	340	$	343
General and administrative		371		538

Total stock-based compensation expense	$	711	$	881

The Company uses the Black-Scholes option-pricing model to estimate the fair value of stock-based awards. The determination of the fair value of stock-based awards on the date of grant using an option-pricing model is affected by the value of the Company’s stock price, as well as assumptions regarding subjective variables. These variables include expected stock price volatility over the term of the awards, actual and projected employee stock option exercise behaviors, risk-free interest rate and expected dividends.

The Company estimates the “simplified method” in accordance with Staff Accounting Bulletin (“SAB”) No. 107, “Share-Based Payment”, and SAB No. 110, “Simplified Method for Plain Vanilla Share Options”, to develop the

F-46

expected term of stock option awards that qualify as “plain-vanilla” options. Under this approach, the expected term of the option grant is presumed to be the midpoint between the vesting date and the contractual end of the option grant. The expected term of all other stock options granted is based on the Company’s historical share option exercise experience, which approximates the midpoint between the vesting date and the contractual end of the option grant. The Company estimates volatility of the common stock by using the average share fluctuations of companies similar in size, operations, and life cycle. The risk-free interest rates used in the valuation model are based on U.S. Treasury issues with remaining terms similar to the expected term on the options. The Company does not anticipate paying any dividends in the foreseeable future and therefore used an expected dividend yield of zero.

Management has estimated the forfeiture rate at 7% based on past experience, forfeiture rates and the individuals receiving the options. The Company will monitor actual forfeiture experience and will periodically update forfeiture estimates based on actual experience. As of December 31, 2018, there was total unrecognized compensation expense of approximately $3.7 million, which is expected to be recognized over a period of approximately 3.96 years.

Stock Options Granted to Employees

During the years ended December 31, 2018 and 2017, the Company granted 731,967 stock options and 108,500 stock options, respectively, to employees andnon-employee directors to purchase shares of common stock with a weighted-average grant date fair value of $4.16 and $4.02 per share, respectively, and a weighted-average exercise price of $5.68 and $5.45 per share, respectively.

The assumptions used to calculate the fair value of stock options granted to employees andnon-employee directors under the 2009 Plan are as follows, presented on a weighted average basis:


	2018			2017
Expected term (in years)		6.1			6.1
Expected volatility		85.43	%		88.19	%
Risk free interest rate		2.77	%		2.16	%
Expected dividend yield		—	%		—	%

The stock-based compensation expense related to employee stock options was approximately $0.6 million for the years ended December 31, 2018 and 2017.

Stock Options Granted toNon-employees

During the years ended December 31, 2018 and 2017, the Company granted 44,000 stock options and 25,000 stock options, respectively, to persons other than employees andnon-employee members of the Company’s Board of Directors with a weighted-average exercise price of $5.68 and $5.34 per share, respectively.

The assumptions used to calculate the fair value of stock options granted tonon-employees under the 2009 Plan are as follows, presented on a weighted average basis:


	2018			2017
Expected term (in years)		9.96			9.85
Expected volatility		86.17	%		84.39	%
Risk free interest rate		2.69	%		2.35	%
Expected dividend yield		—	%		—	%

The stock-based compensation expense related tonon-employee stock options was approximately $0.1 million and $0.2 million for the years ended December 31, 2018 and 2017, respectively.

SUBSEQUENT EVENTS

Bridge Financing—Convertible Promissory Notes with Warrants

In March 2019, the Company initiated a convertible promissory notes offering pursuant to which the Company issued unsecured convertible promissory notes (the “Prom Notes”), bearing interest at 12.00% and maturing in one year and can be converted into shares of SeriesC-1 redeemable convertible preferred stock or the most senior preferred equity outstanding at the time of conversion at the option of the holder at a conversion price of $10.72 per share. In addition, the Prom Notes will automatically convert at maturity or if a qualified financing of at least $15.0 million occurs before maturity, such mandatory conversion price will equal 80% of the effective price per share paid in the qualified financing, but not to exceed $13.40 per share.

The Prom Notes also provide for the issuance of warrants at 50% coverage, which are exercisable into common stock for a term of five years at an exercise price of $14.74 or, upon the occurrence of a qualified financing, 10% premium to the effective price per share paid in the qualified financing.

From March to April 2019, the Company issued Prom Notes and warrants for gross proceeds of $3.6 million.

Evaluation Date

The Company has evaluated events that have occurred after the balance sheet date through April 30, 2019, which is when these financial statements were issued.

1.5Conversion of Shares.

(a) At the Effective Time, by virtue of the Merger and without any further action on the part of Parent, Merger Sub, the Company or any stockholder of the Company or Parent:

(ii) subject toSection 1.5(c), each share of Company Capital Stock outstanding immediately prior to the Effective Time (excluding shares to be canceled pursuant toSection 1.5(a)(i) and excluding Dissenting Shares) shall be automatically converted solely into the right to receive a number of shares of Parent Common Stock equal to the Exchange Ratio (the “Merger Consideration”).

(b) If any shares of Company Capital Stock outstanding immediately prior to the Effective Time are unvested or are subject to a repurchase option or a risk of forfeiture under any applicable restricted stock purchase agreement or other similar agreement with the Company, then the shares of Parent Common Stock issued in exchange for such shares of Company Capital Stock will to the same extent be unvested and subject to the same repurchase option or risk of forfeiture, and such shares of Parent Common Stock shall accordingly be marked with appropriate legends. The Company shall take all actions that may be necessary to ensure that, from and after the Effective Time, Parent is entitled to exercise any such repurchase option or other right set forth in any such restricted stock purchase agreement or other agreement in accordance with its terms.

(c) No fractional shares of Parent Common Stock shall be issued in connection with the Merger, and no certificates or scrip for any such fractional shares shall be issued. Any holder of Company Capital Stock who would otherwise be entitled to receive a fraction of a share of Parent Common Stock (after aggregating all fractional shares of Parent Common Stock issuable to such holder) shall, in lieu of such fraction of a share and upon surrender by such holder of a letter of transmittal in accordance withSection 1.7 and any accompanying documents as required therein, be paid in cash the dollar amount (rounded to the nearest whole cent), without interest, determined by multiplying such fraction by the Parent Closing Price.

(g) If, between the time of calculating the Exchange Ratio and the Effective Time, the outstanding shares of Company Capital Stock or Parent Common Stock shall have been changed into, or exchanged for, a different number of shares or a different class, by reason of any stock dividend, subdivision, reclassification, recapitalization, split (including the Reverse Split), combination or exchange of shares or other like change, the Exchange Ratio shall, to the extent necessary, be equitably adjusted to reflect such change to the extent necessary to provide the holders of Company Capital Stock, Parent Common Stock, Company Options and Company Warrants with the same economic effect as contemplated by this Agreement prior to such stock dividend, subdivision, reclassification, recapitalization, split (including the Reverse Split), combination or exchange of shares or other like change;provided, however, that nothing herein will be construed to permit the Company or Parent to take any action with respect to Company Capital Stock or Parent Common Stock, respectively, that is prohibited or not expressly permitted by the terms of this Agreement.

1.6Closing of the Company’s Transfer Books. At the Effective Time: (a) all shares of Company Capital Stock outstanding immediately prior to the Effective Time shall be treated in accordance withSection 1.5, and all holders of certificates representing shares of Company Capital Stock that were outstanding immediately prior to the Effective Time shall cease to have any rights as stockholders of the Company; and (b) the stock transfer books of the Company shall be closed with respect to all shares of Company Capital Stock outstanding immediately prior to the Effective Time. No further transfer of any such shares of Company Capital Stock shall be made on such stock transfer books after the Effective Time. If, after the Effective Time, a valid certificate previously representing any shares of Company Capital Stock outstanding immediately prior to the Effective Time (a “Company Stock Certificate”) is presented to the Exchange Agent or to the Surviving Corporation, such Company Stock Certificate shall be canceled and shall be exchanged as provided inSections 1.5 and1.7.

1.7Surrender of Certificates.

(a) On or prior to the Closing Date, Parent and the Company shall agree upon and select a reputable bank, transfer agent or trust company to act as exchange agent in the Merger (the “Exchange Agent”). At the Effective Time, Parent shall deposit with the Exchange Agent: (i) certificates or evidence of book-entry shares representing the Parent Common Stock issuable pursuant toSection 1.5 and (ii) cash sufficient to make payments in lieu of fractional shares in accordance withSection 1.5(c). The Parent Common Stock and cash amounts so deposited with the Exchange Agent, together with any dividends or distributions received by the Exchange Agent with respect to such shares, are referred to collectively as the “Exchange Fund.”

(b) Promptly after the Effective Time, the Parties shall cause the Exchange Agent to mail to the Persons who were record holders of shares of Company Capital Stock that were converted into the right to receive the Merger Consideration: (i) a letter of transmittal in customary form and containing such provisions as Parent may reasonably specify (including a provision confirming that delivery of Company Stock Certificates shall be effected, and risk of loss and title to Company Stock Certificates shall pass, only upon proper delivery of such Company Stock Certificates to the Exchange Agent); and (ii) instructions for effecting the surrender of Company Stock Certificates in exchange for shares of Parent Common Stock. Upon surrender of a Company Stock Certificate to the Exchange Agent for exchange, together with a duly executed letter of transmittal and such other documents as may be reasonably required by the Exchange Agent or Parent: (A) the holder of such Company Stock Certificate shall be entitled to receive in exchange therefor a certificate or certificates or book-entry shares representing the Merger Consideration (in a number of whole shares of Parent Common Stock) that such holder has the right to receive pursuant to the provisions ofSection 1.5 (and cash in lieu of any fractional share of Parent Common Stock pursuant to the provisions ofSection 1.5(c)); and (B) the Company Stock Certificate so surrendered shall be canceled. Until surrendered as contemplated by thisSection 1.7(b), each

A-9

Company Stock Certificate shall be deemed, from and after the Effective Time, to represent only the right to receive a certificate or certificates or book-entry shares of Parent Common Stock representing the Merger Consideration (and cash in lieu of any fractional share of Parent Common Stock). If any Company Stock Certificate shall have been lost, stolen or destroyed, Parent may, in its discretion and as a condition precedent to the delivery of any shares of Parent Common Stock, require the owner of such lost, stolen or destroyed Company Stock Certificate to provide an applicable affidavit with respect to such Company Stock Certificate and post a bond indemnifying Parent against any claim suffered by Parent related to the lost, stolen or destroyed Company Stock Certificate as Parent may reasonably request. In the event of a transfer of ownership of a Company Stock Certificate that is not registered in the transfer records of the Company, payment of the Merger Consideration may be made to a Person other than the Person in whose name such Company Stock Certificate so surrendered is registered if such Company Stock Certificate shall be properly endorsed or otherwise be in proper form for transfer and the Person requesting such payment shall pay any transfer or other Taxes required by reason of the transfer or establish to the reasonable satisfaction of Parent that such Taxes have been paid or are not applicable. The Merger Consideration and any dividends or other distributions as are payable pursuant toSection 1.7(c) shall be deemed to have been in full satisfaction of all rights pertaining to Company Capital Stock formerly represented by such Company Stock Certificates.

(c) No dividends or other distributions declared or made with respect to Parent Common Stock with a record date on or after the Effective Time shall be paid to the holder of any unsurrendered Company Stock Certificate with respect to the shares of Parent Common Stock that such holder has the right to receive in the Merger until such holder surrenders such Company Stock Certificate or provides an affidavit of loss or destruction in lieu thereof in accordance with thisSection 1.7 (at which time (or, if later, on the applicable payment date) such holder shall be entitled, subject to the effect of applicable abandoned property, escheat or similar Laws, to receive all such dividends and distributions, without interest).

(d) Any portion of the Exchange Fund that remains undistributed to holders of Company Stock Certificates as of the date that is one year after the Closing Date shall be delivered to Parent upon demand, and any holders of Company Stock Certificates who have not theretofore surrendered their Company Stock Certificates in accordance with thisSection 1.7 shall thereafter look only to Parent for satisfaction of their claims for Parent Common Stock, cash in lieu of fractional shares of Parent Common Stock and any dividends or distributions with respect to shares of Parent Common Stock.

(e) Each of the Exchange Agent, Parent and the Surviving Corporation shall be entitled to deduct and withhold from any consideration deliverable pursuant to this Agreement to any holder of any Company Stock Certificate such amounts as are required to be deducted or withheld from such consideration under the Code or under any other applicable Law. To the extent such amounts are so deducted or withheld, and remitted to the appropriate taxing authority, such amounts shall be treated for all purposes under this Agreement as having been paid to the Person to whom such amounts would otherwise have been paid.

(f) No party to this Agreement shall be liable to any holder of any Company Stock Certificate or to any other Person with respect to any shares of Parent Common Stock (or dividends or distributions with respect thereto) or for any cash amounts delivered to any public official pursuant to any applicable abandoned property Law, escheat Law or similar Law.

(g) All shares of Parent Common Stock issued pursuant to this Agreement shall bear a legend (and Parent will make a notation on its transfer books to such effect) prominently stamped or printed thereon or the substance of which will otherwise be reflected on the books and records of the transfer agent for Parent Common Stock with respect to book-entry shares, in each case reading substantially as follows:

“THE SECURITIES REPRESENTED HEREBY HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED, OR APPLICABLE STATE SECURITIES LAWS. THESE SECURITIES HAVE BEEN ACQUIRED FOR INVESTMENT PURPOSES

A-10

AND NOT WITH A VIEW TO RESALE IN CONNECTION WITH A DISTRIBUTION AND MAY NOT BE SOLD OR OTHERWISE TRANSFERRED EXCEPT PURSUANT TO AN EFFECTIVE REGISTRATION STATEMENT FOR SUCH SECURITIES UNDER THE SECURITIES ACT OF 1933, AS AMENDED, AND APPLICABLE STATE SECURITIES LAWS, OR AN EXEMPTION FROM REGISTRATION UNDER SUCH ACT.”

1.8Appraisal Rights.

(a) Notwithstanding any provision of this Agreement to the contrary, shares of Company Capital Stock that are outstanding immediately prior to the Effective Time and which are held by stockholders who have exercised and perfected appraisal rights for such shares of Company Capital Stock in accordance with the DGCL (collectively, the “Dissenting Shares”) shall not be converted into or represent the right to receive the Merger Consideration described inSection 1.5 attributable to such Dissenting Shares. Such stockholders shall be entitled to receive payment of the appraised value of such shares of Company Capital Stock held by them in accordance with the DGCL, unless and until such stockholders fail to perfect or effectively withdraw or otherwise lose their appraisal rights under the DGCL. All Dissenting Shares held by stockholders who shall have failed to perfect or shall have effectively withdrawn or lost their right to appraisal of such shares of Company Capital Stock under the DGCL (whether occurring before, at or after the Effective Time) shall thereupon be deemed to be converted into and to have become exchangeable for, as of the Effective Time, the right to receive the Merger Consideration, without interest, attributable to such Dissenting Shares upon their surrender in the manner provided inSections 1.5 and1.7.

(b) The Company shall give Parent prompt written notice of any demands by dissenting stockholders received by the Company, withdrawals of such demands and any other instruments served on the Company and any material correspondence received by the Company in connection with such demands. The Company shall not, except with Parent’s prior written consent, voluntarily make any payment with respect to, or settle or offer to settle, any such demands, or approve any withdrawal of any such demands or agree to do any of the foregoing.

1.9Calculation of Parent Net Cash and Company Net Working Capital. Within five Business Days prior to the date of the Parent’s Stockholder Meeting, (a) Parent shall deliver to the Company a net cash schedule (the “Net Cash Schedule”) setting forth Parent’s good faith estimate of its expected Parent Net Cash (the “Net Cash Calculation”) as prepared by Parent’s chief financial officer, together with the work papers andback-up materials used in preparing the Net Cash Schedule and (b) the Company shall deliver to Parent a net working capital schedule (the “Net Working Capital Schedule”) setting forth the Company’s good faith estimate of its expected Company Net Working Capital (the “Net Working Capital Calculation”) as prepared by the Company’s chief financial officer, together with the work papers andback-up materials used in preparing the Net Working Capital Schedule. The calculations and assumptions used in the Net Cash Schedule and the Net Working Capital Schedule shall be consistent with the presentation and methodologies used in preparing the Parent Net Cash and Company Net Working Capital calculation, as applicable, attached to this Agreement asExhibitI-1orExhibitI-2, which calculations have been prepared for illustrative purposes. Within two Business Days after Parent delivers the Net Cash Schedule to the Company and the Company delivers the Net Working Capital Schedule to Parent (the “Response Date”), the receiving party shall have the right to dispute any part of such Net Cash Schedule or Net Working Capital Schedule, as applicable, by delivering a written notice (the “Dispute Notice”) to that effect to the other party. Any Dispute Notice shall identify in reasonable detail the nature of any proposed revisions to the Net Cash Calculation or Net Working Capital Calculation, as applicable, and will be accompanied by reasonably detailed materials supporting the basis for such proposed revisions. If either party delivers a Dispute Notice on or prior to the Response Date as provided above, then the parties shall attempt to resolve the underlying dispute in good faith for a period of two Business Days (the “Dispute Resolution Period”). If the parties agree on the amount of any of the deviations from the Net Cash Schedule or Net Working Capital Schedule, as applicable, during the Dispute Resolution Period, the Parent Net Cash or Company Net Working Capital amount, as applicable, they agree upon shall be final. If the parties,

A-11

notwithstanding such good faith effort, fail to resolve such dispute within the Dispute Resolution Period, then the parties shall jointly engage an independent accountant of national standing to make a written determination of Parent Net Cash or Company Net Working Capital, as applicable, as promptly as practicable, and such independent accountant’s determination shall be final, absent manifest error or fraud.

1.10Further Action. If, at any time after the Effective Time, any further action is determined by the Surviving Corporation to be necessary or desirable to carry out the purposes of this Agreement or to vest the Surviving Corporation with full right, title and possession of and to all rights and property of the Company, then the officers and directors of the Surviving Corporation shall be fully authorized, and shall use their and its commercially reasonable efforts (in the name of the Company, in the name of Merger Sub, in the name of the Surviving Corporation and otherwise) to take such action.

1.11Withholding. The Parties and the Exchange Agent shall be entitled to deduct and withhold from the consideration otherwise payable pursuant to this Agreement to any holder of Company Capital Stock or any other Person such amounts as such Party or the Exchange Agent may be required to deduct and withhold under the Code or any other Law with respect to the making of such payment. To the extent that amounts are so deducted or withheld and paid to the appropriate Governmental Body, such deducted or withheld amounts shall be treated for all purposes of this Agreement as having been paid to the Person in respect of whom such deduction and withholding was made.

5.1Proxy Statement.

(a) As promptly as practicable after the date of this Agreement, the Parties shall prepare, and Parent shall cause to be filed with the SEC, the Proxy Statement. Parent covenants and agrees that the Proxy Statement, including any pro forma financial statements included therein (and the letter to stockholders, notice of meeting and form of proxy included therewith), will not, at the time that the Proxy Statement or any amendment or supplement thereto is filed with the SEC or is first mailed to the Parent stockholders contain any untrue statement of a material fact or omit to state any material fact required to be stated therein or necessary in order to make the statements made therein, in light of the circumstances under which they were made, not misleading.

(a) Promptly following the date hereof, the Company shall prepare and mail a notice (the “Stockholder Notice”) to every stockholder of the Company that did not execute the Company Stockholder Written Consent.

(d) Notwithstanding anything to the contrary contained in this Agreement, if at any time prior to the approval of Parent Stockholder Matters by the Required Parent Stockholder Vote:

(i) if Parent has received a written Acquisition Proposal (which Acquisition Proposal did not arise out of a material breach ofSection 4.4) from any Person that has not been withdrawn and after consultation with outside legal counsel, the Parent Board shall have determined, in good faith, that such Acquisition Proposal is a Superior Offer, (x) the Parent Board may make a Parent Board Adverse Recommendation Change or (y) Parent may terminate this Agreement pursuant to Section 9.1(h) to enter into a Permitted Alternative Agreement with respect to such Superior Offer, if and only if: (A) the Parent Board determines in good faith, after consultation with Parent’s outside legal counsel, that the failure to do so could be inconsistent with the fiduciary duties of the Parent Board to Parent’s stockholders under applicable Law; (B) Parent shall have given the Company prior written notice of its intention to consider making a Parent Board Adverse Recommendation Change or terminate this Agreement pursuant toSection 9.1(h) at least three Business Days prior to making any such Parent Board Adverse Recommendation Change or termination (a “Determination Notice”) (which notice shall not constitute a Parent Board Adverse Recommendation Change); and (C) (1) Parent shall have provided to the Company a summary of the material terms and conditions of the Acquisition Proposal in accordance withSection 4.4(b), (2) Parent shall have given the Company the three Business Days after the Determination Notice to propose revisions to the terms of this Agreement or make another proposal and shall have made its Representatives reasonably available to negotiate in good faith with the Company (to the extent the Company desires to negotiate) with respect to such proposed revisions or other proposal, if any, and (3) after considering the results of any such negotiations and giving effect to the

A-50

proposals made by the Company, if any, after consultation with outside legal counsel, the Parent Board shall have determined, in good faith, that such Acquisition Proposal is a Superior Offer and that the failure to make the Parent Board Adverse Recommendation Change or terminate this Agreement pursuant toSection 9.1(h) could be inconsistent with the fiduciary duties of the Parent Board to Parent’s stockholders under applicable Law. For the avoidance of doubt, the provisions of thisSection 5.3(d)(i) shall also apply to any material change to the facts and circumstances relating to such Acquisition Proposal and require a new Determination Notice, except that the references to three Business Days shall be deemed to be two Business Days.

(ii) other than in connection with an Acquisition Proposal, the Parent Board may make a Parent Board Adverse Recommendation Change in response to a Parent Change in Circumstance, if and only if: (A) the Parent Board determines in good faith, after consultation with Parent’s outside legal counsel, that the failure to do so could be inconsistent with the fiduciary duties of the Parent Board to Parent’s stockholders under applicable Law; (B) Parent shall have given the Company a Determination Notice at least three Business Days prior to making any such Parent Board Adverse Recommendation Change; and (C) (1) Parent shall have specified the Parent Change in Circumstance in reasonable detail, (2) Parent shall have given the Company the three Business Days after the Determination Notice to propose revisions to the terms of this Agreement or make another proposal, and shall have made its Representatives reasonably available to negotiate in good faith with the Company (to the extent the Company desires to do so) with respect to such proposed revisions or other proposal, if any, and (3) after considering the results of any such negotiations and giving effect to the proposals made by the Company, if any, after consultation with outside legal counsel, the Parent Board shall have determined, in good faith, that the failure to make the Parent Board Adverse Recommendation Change in response to such Parent Change in Circumstance could be inconsistent with the fiduciary duties of the Parent Board to Parent’s stockholders under applicable Law. For the avoidance of doubt, the provisions of thisSection 5.3(d)(ii) shall also apply to any material change to the facts and circumstances relating to such Parent Change in Circumstance and require a new Determination Notice, except that the references to three Business Days shall be deemed to be two Business Days.

(e) Nothing contained in this Agreement shall prohibit Parent or the Parent Board from (i) complying with Rules14d-9 and14e-2(a) promulgated under the Exchange Act, (ii) issuing a “stop, look and listen” communication or similar communication of the type contemplated by Section 14d-9(f) under the Exchange Act or (iii) otherwise making any disclosure to the Parent stockholders;provided however, that in the case of the foregoing clause (iii) the Parent Board determines in good faith, after consultation with its outside legal counsel, that failure to make such disclosure could be reasonably likely to be inconsistent with applicable Law, including its fiduciary duties under applicable Law.

5.4Regulatory Approvals.

(a) Each Party shall use reasonable best efforts to file or otherwise submit, as soon as practicable after the date of this Agreement, all applications, notices, reports, filings and other documents reasonably required to be filed by such Party with or otherwise submitted by such Party to any Governmental Body with respect to the Contemplated Transactions, and to submit promptly any additional information requested by any such Governmental Body.

(b) Without limiting the generality of the foregoing, each of Parent and the Company shall make any filings (“Merger Notification Filings”) required by any applicable Antitrust Laws. The parties hereto shall promptly supply one another with any information that may be required in order to make such filings or obtain such consents and approvals. Each party hereto shall (i) consult and cooperate with one another, and consider in good faith the views of one another, in connection with any analyses, appearances, presentations, memoranda, briefs, arguments, opinions and proposals made or submitted by or on behalf of any party hereto in connection

A-51

with proceedings under or relating to any Antitrust Law, (ii) coordinate with one another in preparing and exchanging such materials and (iii) promptly provide one another (and its counsel) with copies of all filings, presentations or submissions made by such party to any Governmental Body in connection with this Agreement. In addition, any party may, as it deems advisable and necessary, reasonably designate any confidential and competitively sensitive material provided to the other parties under thisSection 5.4 as “Outside Counsel Only” or redact information regarding valuation or negotiation strategy. Materials identified as “Outside Counsel Only” and the information contained therein shall be given only to the outside legal counsel of the recipient and will not be disclosed by such outside counsel to employees, officers, or directors of the recipient, unless express written permission is obtained in advance from the source of the materials.

(c) Each of Parent and the Company shall use its respective reasonable best efforts to resolve objections, if any, as may be asserted by any Governmental Body with respect to the Contemplated Transactions under any applicable Antitrust Laws, including responding promptly to and complying with any requests for information relating to this Agreement or the Merger Notification Filings from any Governmental Body charged with enforcing, applying, administering or investigating any Antitrust Laws.

(d) Notwithstanding anything to the contrary herein (i) Parent shall not have any obligation to litigate or contest any such Legal Proceeding or order resulting therefrom and (ii) Parent shall be under no obligation to make proposals, execute or carry out agreements or submit to orders providing for (A) the sale, license, divestiture, or other disposition or holding separate of any assets of Parent or the Company or any of their respective Affiliates, (B) the imposition of any limitation or restriction on the ability of Parent or any of its Affiliates to freely conduct their business or, following the Closing, the business of the Company, or (C) any limitation or regulation on the ability of Parent or any of its Affiliates to exercise full rights of ownership of the Company.

5.5Company Options; Company Warrants and Company Convertible Notes.

(a) At the Effective Time, each Company Option that is outstanding and unexercised immediately prior to the Effective Time under the Company Plan, whether or not vested, shall be converted into and become an option to purchase Parent Common Stock, and Parent shall assume the Company Plan and each such Company Option in accordance with the terms (as in effect as of the date of this Agreement) of the Company Plan and the terms of the stock option agreement by which such Company Option is evidenced (but with changes to such documents as Parent in good faith determines are appropriate to reflect the substitution of the Company Options by Parent to purchase shares of Parent Common Stock). All rights with respect to Company Common Stock under Company Options assumed by Parent shall thereupon be converted into rights with respect to Parent Common Stock. Accordingly, from and after the Effective Time: (i) each Company Option assumed by Parent may be exercised solely for shares of Parent Common Stock; (ii) the number of shares of Parent Common Stock subject to each Company Option assumed by Parent shall be determined by multiplying (A) the number of shares of Company Common Stock that were subject to such Company Option, as in effect immediately prior to the Effective Time, by (B) the Exchange Ratio, and rounding the resulting number down to the nearest whole number of shares of Parent Common Stock; (iii) the per share exercise price for the Parent Common Stock issuable upon exercise of each Company Option assumed by Parent shall be determined by dividing (A) the per share exercise price of Company Common Stock subject to such Company Option, as in effect immediately prior to the Effective Time, by (B) the Exchange Ratio and rounding the resulting exercise price up to the nearest whole cent; and (iv) any restriction on the exercise of any Company Option assumed by Parent shall continue in full force and effect and the term, exercisability, vesting schedule and other provisions of such Company Option shall otherwise remain unchanged;provided, however, that: (A) Parent may amend the terms of the Company Options and the Company Plan to reflect Parent’s substitution of the Company Options with options to purchase Parent Common Stock (such as by making any change in control or similar definition relate to Parent and having any provision that provides for the adjustment of Company Options upon the occurrence of certain corporate events relate to corporate events that relate to Parent and/or Parent Common Stock); and (B) the Parent Board or a committee thereof shall succeed to the authority and responsibility of the Company Board or any committee thereof with respect to each Company Option assumed by Parent.

A-52

(b) Parent shall file with the SEC, promptly after the Effective Time, a registration statement on FormS-8 (or any successor form), if available for use by Parent, relating to the shares of Parent Common Stock issuable with respect to Company Options assumed by Parent in accordance withSection 5.5(a).

(c) At the Effective Time, each Company Warrant that is outstanding and unexercised as of immediately prior to the Effective Time, if any, shall be converted into and become a warrant to purchase Parent Common Stock and Parent shall assume each such Company Warrant in accordance with its terms. All rights with respect to Company Capital Stock under Company Warrants assumed by Parent shall thereupon be converted into rights with respect to Parent Common Stock. Accordingly, from and after the Effective Time: (i) each Company Warrant assumed by Parent may be exercised solely for shares of Parent Common Stock; (ii) the number of shares of Parent Common Stock subject to each Company Warrant assumed by Parent shall be determined by multiplying (A) the number of shares of Company Common Stock, or the number of shares of Company Preferred Stock issuable upon exercise of the Company Warrant, as applicable, that were subject to such Company Warrant immediately prior to the Effective Time by (B) the Exchange Ratio and rounding the resulting number down to the nearest whole number of shares of Parent Common Stock; (iii) the per share exercise price for the Parent Common Stock issuable upon exercise of each Company Warrant assumed by Parent shall be determined by dividing the per share exercise price of Company Capital Stock subject to such Company Warrant, as in effect immediately prior to the Effective Time, by the Exchange Ratio and rounding the resulting exercise price up to the nearest whole cent; and (iv) any restriction on any Company Warrant assumed by Parent shall continue in full force and effect and the term and other provisions of such Company Warrant shall otherwise remain unchanged.

(d) Prior the Effective Time, the Company shall take all actions (including providing any required notices) that may be necessary to cause all of the outstanding Company Convertible Notes to be converted into shares of Company Capital Stock pursuant to the terms thereof.

Board of Directors

Vical Incorporated

10390 Pacific Center Court

San Diego, California

Members of the Board of Directors:

We understand that Vical Incorporated, a Delaware corporation ( “Vical” or “Parent”), proposes to enter into an Agreement and Plan of Merger, expected to be dated as of June 2, 2019 (the “Merger Agreement”), by and among Vical, Victory Subsidiary, Inc., a Delaware corporation and wholly-owned subsidiary of Vical (“Merger Sub”), and Brickell Biotech, Inc., a Delaware corporation (“Brickell” or “Company”), which provides, among other things, for the merger of Merger Sub with and into Brickell (the “Merger”) with Brickell continuing as the surviving entity in the Merger as a wholly-owned subsidiary of Vical. As a result of the Merger, (i) each outstanding share of Company Capital Stock (as defined in the Merger Agreement), other than Excluded Shares (as defined below), shall be converted solely into the right to receive a number of shares of Vical’s common stock, par value $0.01 per share (“Vical Common Stock”), equal to the Exchange Ratio, (ii) all outstanding Company Options and Company Warrants (as such terms are defined in the Merger Agreement) shall, upon exercise or conversion, as the case may be, be converted into an option or warrant to purchase a number of shares of Vical Common Stock, at an exercise price, based upon the Exchange Ratio, and (iii) all outstanding Company Convertible Notes (as defined in the Merger Agreement) shall be converted into shares of Company Capital Stock prior to the Effective Time of the Merger (as defined in the Merger Agreement). As used herein, (a) the “Exchange Ratio” is the number of shares of Vical Common Stock to be received by holders of Company Outstanding Shares (as defined in the Merger Agreement) that is derived from the agreed relative percentage ownership of the combined company by holders of Company Outstanding Shares (referred to in the Merger Agreement as the “Company Allocation Fraction”) and Parent Outstanding Shares (as defined in the Merger Agreement; such percentage ownership is referred to in the Merger Agreement as the “Parent Allocation Fraction”) following the consummation of the Merger, which are, subject to certain adjustments set forth in the Merger Agreement (as to which adjustments we express no opinion), equal to 60% and 40%, respectively; and (b) “Excluded Shares” means (1) shares of Company Capital Stock that are held in treasury or by Brickell or Merger Sub immediately prior to the Effective Time and (2) any shares of Company Capital Stock held by a holder who is entitled to and properly demands appraisal rights in accordance with Section 262 of the Delaware General Corporation Law. The terms and conditions of the Merger are more fully set forth in the Merger Agreement and capitalized terms used but not defined herein shall have the meanings ascribed to such terms in the Merger Agreement.

The Board of Directors of Vical (in its capacity as such) has requested our opinion, as investment bankers, as to the fairness, from a financial point of view and as of the date hereof, of the Exchange Ratio to holders of Vical Common Stock.

In the course of performing our review and analyses for rendering the opinion set forth below, we have:

Without limiting the generality of the foregoing, with respect to the Projections, we have assumed, with your consent, and based upon discussions with the management of Vical that they have been reasonably prepared in good faith, that the Projections reflect the best currently available estimates and judgments of the management of Vical of the future results of operations and financial performance of Brickell. We express no view as to the Projections or the assumptions on which they are based and we assume no responsibility for the accuracy or completeness thereof.

In arriving at our opinion set forth below, we have made no analysis of, and express no opinion as to, the adequacy of the reserves of Vical or Brickell. In addition, we have not made any independent evaluations or appraisals of the assets or liabilities of Vical or Brickell or any of their respective subsidiaries, and we have not been furnished with any such evaluations or appraisals, nor have we evaluated the solvency of Vical, Brickell or any other entity under any state or federal law relating to bankruptcy, insolvency or similar matters. We have assumed that there has been no material change in the assets, financial condition, business or prospects of Vical or Brickell since the date of the most recent relevant financial information made available to us. Without limiting the generality of the foregoing, we have undertaken no independent analysis of any pending or threatened litigation, regulatory action, possible unasserted claims or other contingent liabilities to which Vical, Brickell or any of their respective affiliates is a party or may be subject, and, at your direction and with your consent, our

opinion makes no assumption concerning, and therefore does not consider, the possible assertion of claims, outcomes or damages arising out of any such matters. We have also assumed that neither Vical nor Brickell is party to any material pending transaction that has not been disclosed to us, including, without limitation, any financing, recapitalization, acquisition or merger, divestiture orspin-off, other than the Merger, the Concurrent Financing (as defined in the Merger Agreement), and transactions contemplated by the Note Purchase Agreement (as defined in the Merger Agreement). In addition, we have not conducted, nor have assumed any obligation to conduct, any physical inspection of the properties or facilities of Vical or Brickell. We have assumed, at your direction and with your consent, that the only material asset of Vical is the Parent Net Cash (as defined in the Merger Agreement), that no other assets of Vical, including, without limitation, any net operating losses of Vical, have any material value and that Vical does not, and does not intend to, engage in any activity that may result in the generation of any revenue. We have also been instructed by Vical, and have assumed, at your direction and with your consent, that (i) (a) Parent Net Cash at the closing of the Merger is expected to be $34.7 million but in no case less than $30 million, (b) if Parent Net Cash is between $34.2 million and $35.2 million at the closing of the Merger, then no adjustment will be made, and (c) outside of such range, Vical’s valuation will be adjusted on adollar-for-dollar basis; and (ii) (a) the Company Net Working Capital (as defined in the Merger Agreement) is expected to be between –$9,200,000 and –$10,200,000, and (b) outside of such range, Brickell’s valuation will be adjusted on adollar-for-dollar basis.

We have assumed that the representations and warranties of each party contained in the Merger Agreement and in all other related documents and instruments that are referred to therein are and will be true and correct as of the date or the dates made or deemed made, that each party thereto will fully and timely perform all of the covenants and agreements required to be performed by it under the Merger Agreement and any other agreement contemplated thereby, that the transactions contemplated by the Merger Agreement, including, without limitation, the Merger, will be consummated in accordance with the terms of the Merger Agreement without waiver, modification or amendment of any term, condition or agreement. We have assumed that the final form of the Merger Agreement will be in all material respects identical to the Draft Merger Agreement. We have, with your consent, further assumed that any adjustment to the Exchange Ratio pursuant to the terms of the Merger Agreement will not result in any adjustment to the Exchange Ratio that is material to our analysis. We have also assumed that any governmental, regulatory and other consents and approvals contemplated in connection with the Merger will be obtained and that, in the course of obtaining any of those consents and approvals, no restrictions will be imposed or waivers made that would have an adverse effect on Vical, Brickell or the contemplated benefits of the Merger.

Our opinion set forth below is necessarily based on economic, market, financial and other conditions as they exist, and on the information made available to us, as of the date of this letter. We have not considered any potential legislative or regulatory changes currently being considered by the United States Congress, the Securities and Exchange Commission (the “SEC”), or any other governmental or regulatory bodies, or any changes in accounting methods or generally accepted accounting principles that may be adopted by the SEC or the Financial Accounting Standards Board. It should be understood that, although subsequent developments may affect the conclusion reached in such opinion, we do not have any obligation to update, revise or reaffirm the opinion set forth below. Our opinion set forth below addresses solely the fairness, from a financial point of view and as of the date hereof, of the Exchange Ratio to the holders of Vical Common Stock and does not address any other terms in the Merger Agreement, or any other agreement contemplated by the Merger Agreement or relating to the Merger or any other aspect or implication of the Merger, including, without limitation, the form or structure of the Merger or the fairness of the Merger or the Exchange Ratio to any other securityholders or creditors or any other constituency of Vical. Our opinion set forth below does not address Vical’s underlying business decision to proceed with the Merger or the relative merits of the Merger compared to other alternatives

available to Vical. We express no opinion as to the prices or ranges of prices at which shares of securities of any person, including Vical or Brickell, will trade at any time, including following the announcement or consummation of the Merger. We have not been requested to opine as to, and our opinion does not in any manner address, the amount or nature of compensation to any of the officers, directors or employees of any party to the Merger, or any class of such persons, relative to the compensation to be paid to the holders of Vical Common Stock in connection with the Merger or with respect to the fairness of any such compensation.

It is understood that this letter and the opinion set forth below are provided to the Board of Directors of Vical (in its capacity as such) for its information in connection with its consideration of the Merger and may not be used for any other purpose or disclosed, referred to, or communicated (in whole or in part) to any third party for any purpose whatsoever without our prior written consent, except that a copy of this letter may be included in its entirety in any filing Vical or Brickell is required to make with the SEC in connection with the Merger if such inclusion is required by applicable law. The opinion set forth below does not constitute a recommendation to the Board of Directors of Vical or Brickell, or any stakeholder or stockholder of Vical or Brickell, as to how to vote on or to take any other action in connection with the Merger (including, without limitation, whether or not any holder of Vical Common Stock should enter into any voting, stockholders’ or affiliates’ agreement with respect to the Merger).

As part of our investment banking services, we are regularly engaged in the valuation of businesses and securities in connection with mergers and acquisitions, and for other purposes. We have acted as Vical’s financial advisor in connection with the Merger and will receive a fee for our services, a significant portion of which is contingent upon consummation of the Merger. In addition, Vical has agreed to reimburse our expenses and indemnify us for certain liabilities that may arise out of our engagement. We will also receive an additional fee for rendering the opinion set forth below which is not contingent upon consummation of the Merger. We or our affiliates may also seek to provide financial advisory, financing and other investment banking services to Vical and Brickell and/or certain of their respective affiliates in the future and expect to receive fees for the rendering of any such services. In the ordinary course of business, we and our clients may transact in the equity and debt securities of Vical and may at any time hold a long or short position in such securities.

The opinion set forth below was reviewed and approved by a fairness committee of MTS Securities, LLC.

Based upon and subject to the foregoing, it is our opinion that, as of the date hereof, the Exchange Ratio is fair, from a financial point of view, to holders of Vical Common Stock.

Very truly yours,

Each stock certificate that, immediately prior to the Effective Time, represented shares of Common Stock that were issued and outstanding immediately prior to the Effective Time shall, from and after the Effective Time, automatically and without the necessity of presenting the same for exchange, represent that number of whole shares of Common Stock after the Effective Time into which the shares formerly represented by such certificate have been reclassified (as well as the right to receive cash in lieu of fractional shares of Common Stock after the Effective Time); provided, however, that each person of record holding a certificate that represented shares of Common Stock that were issued and outstanding immediately prior to the Effective Time shall receive, upon surrender of such certificate, a new certificate evidencing and representing the number of whole shares of Common Stock after the Effective Time into which the shares of Common Stock formerly represented by such certificate shall have been reclassified.”
