Ladies and Gentlemen:

Halozyme Therapeutics, Inc., a Delaware corporation (the “Company” or “you”), has advised BofA Securities, Inc. (together with its designated affiliates, “BofA Securities” and the “Lead Arranger”) and Bank of America, N.A. (“Bank of America” and the “Initial Lender”, together with BofA Securities, “BofA”; the Initial Lender and the Lead Arranger are collectively referred to herein as the “Commitment Parties”, “we” or “us”) that it (directly or through one or more of its wholly owned subsidiaries) intends to acquire (the “Acquisition”) Antares Pharma, Inc., a Delaware corporation (“Atlas”), pursuant to the Agreement and Plan of Merger among the Company, Atlas Merger Sub, Inc. and Atlas, dated as of April 12, 2022 (the “Transaction Agreement”) and to consummate the other Transactions (as defined below). Each capitalized term used but not defined herein shall have the meaning assigned to it in the Summary of Terms and Conditions attached hereto as Exhibit B (the “Term Sheet”) or in the Existing Credit Agreement (as defined below), as applicable.

In connection with the consummation of the Acquisition and the incurrence of the Term Loan Facility (as defined below), you have advised us that you intend to either (i) amend that certain Credit Agreement dated as of December 23, 2021, by and among the Company, Halozyme, Inc., a California corporation, each lender from time to time party thereto, and Bank of America, N.A., as administrative agent, a swing line lender and an L/C issuer (the “Existing Credit Agreement” and the revolving credit facility thereunder, the “Existing Revolving Credit Facility”) to make the changes described on Exhibit A hereto (the “Amendment”) or (ii) terminate the commitments under the Existing Revolving Credit Facility and repay all outstanding obligations thereunder and obtain a new $75.0 million revolving credit facility with terms consistent with the Existing Credit Agreement as modified as described in Exhibit A hereto (the “Revolving Credit Facility”). Each Initial Lender that is a lender under the Existing Credit Agreement hereby agrees to consent to the Amendment. Upon the request of the Company, the Lead Arranger agrees to use its commercially reasonable efforts to assist the Company with

obtaining the consents of the lenders under the Existing Credit Agreement to the Amendment. The Company’s receipt of written consents to the Amendment from each of the Lenders under the Existing Credit Agreement shall be referred to herein as the “Amendment Event”.

You have further advised us that you intend to finance the Acquisition and the costs and expenses related to the Transactions (as hereinafter defined) with (1) a new senior secured term loan credit facility in the aggregate amount of $375.0 million (the “Term Loan Facility” and together with the either the Existing Revolving Credit Facility, as amended by the Amendment, or the Revolving Credit Facility, as applicable, the “Facilities”) and (2) cash on hand.

The solicitation of consents to the Amendment; the Acquisition; the entering into and initial funding of the Facilities (as applicable); the repayment, prepayment, repurchase, redemption, defeasance or discharge (and release of any liens related thereto) or arrangements reasonably satisfactory to the Lead Arranger (other than in respect of letters of credit that are either rolled into or back-stopped by letter(s) of credit issued under the Facilities or cash collateralized by the Borrower or its subsidiaries or contingent obligations not then due and payable) and termination of all commitments thereunder (and termination and release of all related security interests) on or prior to the Closing Date of all indebtedness under (i) the Credit Agreement, dated November 1, 2021, by and among Atlas, as borrower, the lenders party thereto and Wells Fargo Bank, National Association, as administrative agent and (ii) if the Amendment Event does not occur on or prior to the Closing Date, the Existing Revolving Credit Facility (collectively, the “Refinancing”); the payment of fees and expenses in connection therewith; and all related transactions are hereinafter collectively referred to as the “Transactions”.

In connection with the foregoing, Bank of America is pleased to advise you of its commitment to provide (a) 100.0% of the aggregate principal amount of the Term Loan Facility and (b) in the event the Amendment Event does not occur on or prior to the Closing Date, 100.0% of the aggregate principal amount of commitments under the Revolving Credit Facility, in each case, upon the terms and subject to the conditions set forth or referred to in this Commitment Letter and the Term Sheet.

It is agreed that (i) the Lead Arranger will act as the sole lead arranger and sole bookrunner for the Facilities and (ii) Bank of America will act as administrative agent and collateral agent for the Facilities, and each of them will, in such capacities, perform the duties and exercise the authority customarily performed and exercised by it in such roles. You and the Commitment Parties further agree that no other titles will be awarded, and no other compensation will be paid (other than as expressly contemplated by this Commitment Letter and the Fee Letter referred to below) in connection with the Facilities unless you and the Lead Arranger shall so agree.

Notwithstanding the foregoing, you shall have the right (in consultation with the Lead Arranger), at any time on or prior to the 15th business day following the date of this Commitment Letter, to appoint one additional joint lead arranger and joint bookrunner or confer other titles with respect to the Facilities in a manner and with economics determined by you and reasonably acceptable to the Lead Arranger (the “Additional Agent”); provided that the aggregate economics payable to such Additional Agent in respect of the Facilities shall not exceed twenty percent (20%) of the total economics which would otherwise be payable to the Initial Lender pursuant to the Fee Letter (exclusive of any fees payable to the administrative agent in its capacity as such) (it being understood that (i) the commitment of the Initial Lender hereunder will be reduced dollar-for-dollar by the amount of the commitments of such Additional Agent (or its relevant affiliate) (each, an “Additional Initial Lender”) under each Facility, upon the execution of customary joinder documentation reasonably satisfactory to the Lead Arranger and (ii) the commitments assumed by such Additional Initial Lender for each Facility will be in proportion to the economics allocated to such Additional Agent and ratable across all Facilities. Each party hereto agrees to

execute such joinder agreements, amendments, amendments and restatements and other documents with respect to this Commitment Letter and the Fee Letter as are required to give effect to this paragraph.

The Initial Lender reserves the right, prior to or after the execution of definitive documentation for any Facility, to syndicate all or a portion of its commitments in respect of such Facility hereunder to one or more financial institutions identified by the Lead Arranger in consultation with you and reasonably acceptable to the Lead Arranger and you (such consent not to be unreasonably withheld or delayed), that will become parties to such definitive documentation pursuant to a syndication to be managed by the Lead Arranger (the Initial Lender and other the financial institutions becoming parties to such definitive documentation being collectively referred to as the “Lenders”). You agree until the date that is the earlier of (i) 60 days after the Closing Date and (ii) the date on which a Successful Syndication (as defined in the Fee Letter) is achieved (such earlier date referred to in clauses (i) and (ii), the “Syndication Date”) actively to assist, and to use commercially reasonable efforts (consistent with the terms of the Transaction Agreement) to cause Atlas to assist, the Lead Arranger in completing an orderly Successful Syndication of each Facility. In that regard, you agree promptly to prepare and provide to the Lead Arranger such information with respect to the Company and its subsidiaries, and to use commercially reasonable efforts (consistent with the terms of the Transaction Agreement) to cause Atlas promptly to prepare and provide to the Lead Arranger such information with respect to Atlas and its subsidiaries, in each case including financial information, as the Lead Arranger may reasonably request in connection with the arrangement and syndication of each Facility; provided that the only financial statements that you or Atlas shall be required to deliver are those financial statements described in paragraph 3 of Exhibit C attached hereto. Your assistance shall also include (a) your using commercially reasonable efforts to ensure that the syndication efforts benefit from your existing lending and investment banking relationships, (b) direct contact between appropriate senior management of the Company and the proposed Lenders, (c) your assistance, and your using commercially reasonable efforts (consistent with the terms of the Transaction Agreement) to cause Atlas to assist, in the preparation of a confidential information memorandum and other marketing materials to be used in connection with the syndication of each Facility (collectively, “Information Materials”) and (d) the hosting, with the Lead Arranger, of a single lender meeting and a reasonable number of conference calls with prospective Lenders at times to be mutually agreed. In addition, to facilitate an orderly Successful Syndication of each Facility, you agree that, until the later of the Closing Date and the completion of a Successful Syndication of each Facility you and your subsidiaries will not (and you will use commercially reasonable efforts (consistent with the terms of the Transaction Agreement) to cause Atlas and its subsidiaries not to) issue, sell, offer, place or arrange any debt securities or commercial bank or other credit facilities of the Company, Atlas or their respective subsidiaries that could reasonably be expected to materially and adversely impair the primary syndication of such Facility, other than (i) the Facilities, (ii) any debt facilities of the Company arranged by the Lead Arranger and (iii) any debt permitted to be incurred by the Transaction Agreement, in each case without the written consent of the Lead Arranger (not to be unreasonably withheld or delayed). Without limiting your obligations to assist with the syndication efforts as set forth herein and notwithstanding anything to the contrary contained in this Commitment Letter, the Term Sheet, the Fee Letter or the definitive documentation for the Facilities and the Amendment, the Initial Lender agrees that neither the commencement of any syndication nor the completion of a Successful Syndication nor the obtaining of ratings nor your compliance with this paragraph in any other manner shall constitute a condition to the funding under any Facility and the effectiveness of the Amendment on the Closing Date.

You agree, at the request of the Lead Arranger, to assist, and to use commercially reasonable efforts (consistent with the terms of the Transaction Agreement) to cause Atlas to assist, in the preparation of an additional version of the Information Materials to be used by prospective Lenders’ public-side employees and representatives who do not wish to receive material non-public information (within the meaning of United States Federal securities laws) with respect to the Company, Atlas, their

respective subsidiaries and any securities of any of the foregoing (“MNPI”) and who may be engaged in investment and other market related activities with respect to the Company, Atlas, their respective subsidiaries or any securities of any of the foregoing. It is understood that, in connection with your assistance described above, you will provide customary authorization letters (and you will use commercially reasonable efforts consistent with the terms of the Transaction Agreement, to have Atlas provide such letters) to the Lead Arranger authorizing the distribution of the Information Materials to prospective Lenders and, in the case of any distribution of any Information Materials to “public-siders”, containing a representation that such Information Materials do not contain MNPI and a customary “10b-5” representation. You agree that the following documents may be distributed to both “private-siders” and “public-siders” unless you advise the Lead Arranger in writing (including by email) within a reasonable time prior to their intended distribution that such materials should only be distributed to “private-siders” and provided that you shall have been given a reasonable opportunity to review such documents: (a) the Term Sheet, (b) administrative materials prepared by any Lead Arranger for prospective Lenders (such as lender meeting invitations, lender allocations and funding and closing memoranda), (c) notifications of changes in the terms of the Facilities and the Amendment, and (d) drafts of the definitive documentation for the Facilities and Amendment. If you advise us that any of the foregoing should be distributed only to “private-siders”, then “public-siders” will not receive such materials without further discussions with you.

You hereby represent and covenant that (a) all written information, other than the Projections (as defined below) and information of a general economic or industry nature, that has been or will be made available to either the Initial Lender or Lead Arranger by or on behalf of you in connection with the Transactions (the “Information”) is or, when furnished, will be, in each case when taken as a whole and in light of the circumstances when furnished, correct in all material respects at the time furnished and does not or will not at the time furnished contain any untrue statement of a material fact or omit to state a material fact necessary in order to make the statements contained therein, taken as a whole, not materially misleading in light of the circumstances under which such statements are made and (b) the projections, financial estimates, forecasts and other forward-looking information that have been or will be made available to either the Initial Lender or Lead Arranger by or on behalf of you in connection with the Transactions (the “Projections”) have been or will be prepared in good faith based upon assumptions believed by you to be reasonable at the time made and at the time the Projections are so made available (it being understood that the Projections, by their nature, are inherently uncertain and no assurances are being given that the results reflected in the Projections will be achieved); provided that, with respect to any Information or Projections prepared by or relating to Atlas or its subsidiaries, the foregoing representations are made only to the best of your knowledge. You agree that if at any time until the later of the Syndication Date and the Closing Date you become aware that the representations in the immediately preceding sentence would not be true in any material respect if the Information and Projections were being furnished, and such representations were being made, at such time, then you will (and with respect to Atlas, use your commercially reasonable efforts to cause Atlas to) promptly supplement the Information and the Projections so that such representations or warranties would be true in all material respects under those circumstances. You understand that in connection with the syndication of the Facilities and the Amendment we will use and rely on the Information without independent verification thereof. Notwithstanding the foregoing, it is understood that the Initial Lender’s commitments hereunder are not subject to or conditioned upon the accuracy of the representations set forth in this paragraph, and notwithstanding anything to the contrary contained in this Commitment Letter, the Term Sheet, the Fee Letter or the definitive documentation for the Facilities, the accuracy of such representations shall not constitute a condition to the funding under any Facility or the effectiveness of the Amendment on the Closing Date.

The Lead Arranger will, in consultation with you, manage all aspects of the syndication of the Facilities, including decisions as to the selection of institutions to be approached and when they will be approached, when their commitments will be accepted, which institutions will participate, the allocations of the commitments among the Lenders, the allocation of any title or role to any Lender and the amount and distribution of fees among the Lenders; it being understood and agreed that we will not syndicate to those persons identified in writing to the Lead Arranger on or prior to our execution of this Commitment Letter and, with respect to persons who are competitors of you or your subsidiaries or Atlas or its subsidiaries, identified in writing from time to time after the date of this Commitment Letter and, in each case, their affiliates (other than bona fide debt fund affiliates of competitors) to the extent such affiliates are identified in writing or are otherwise clearly identifiable on the basis of name (but, in each case, without retroactive effect) (collectively, the “Disqualified Lenders”). Notwithstanding the Lead Arranger’s right to syndicate the Facilities (but subject to the seventh paragraph of this Commitment Letter), the Initial Lender shall not be relieved or released from its commitment hereunder prior to the funding thereof on the Closing Date in connection with any syndication, assignment or participation of any Facility (and unless you otherwise agree in writing, the Initial Lender and Lead Arranger shall at all times retain exclusive control over all its rights and obligations with respect to such Facility and its commitments in respect thereof, including all rights with respect to consents, modifications, supplements, waivers and amendments of this Commitment Letter and the definitive documentation with respect to such Facility).

As consideration for the Initial Lender’s commitment hereunder and our agreements to perform the services described herein, you agree to pay to us the fees as set forth in the fee letter dated the date hereof and delivered herewith (the “Fee Letter”).

The commitments of the Initial Lender and the agreements of the Initial Lender and the Lead Arranger hereunder in respect of each Facility and the Amendment are subject only to satisfaction or waiver of the following conditions (collectively, the “Funding Conditions”): (a) the execution and delivery by the Borrower and the Guarantors of definitive documentation for such Facility and the Amendment consistent with this Commitment Letter, the Term Sheet and the Fee Letter and subject to the Documentation Provision and (b) the satisfaction or waiver of the other conditions expressly set forth in Exhibit C attached hereto. It is understood that there are no conditions (implied or otherwise) to the commitments hereunder (including compliance with the terms of this Commitment Letter, the Term Sheet, the Fee Letter, the definitive documentation for the Facilities or otherwise) other than the Funding Conditions (and upon satisfaction or waiver of the Funding Conditions, the initial funding duly requested by any Borrower under any Facility to be made on or after the date on which the Effective Time occurs shall occur (the date of such funding, the “Closing Date”)).

Notwithstanding anything in this Commitment Letter, the Term Sheet, the Fee Letter, the definitive documentation for the Facilities or any other letter agreement or undertaking concerning the financing of the Transactions to the contrary, (a) the only representations the accuracy of which shall be a condition to availability of the Facilities and the effectiveness of the Amendment on the Closing Date shall be (i) such representations made by Atlas in the Transaction Agreement as are material to the interests of the Lenders, but only to the extent that you (or your affiliates) have the right under the Transaction Agreement to terminate your obligations under the Transaction Agreement or not to consummate the Acquisition as a result of such representations in the Transaction Agreement being inaccurate (the “Transaction Agreement Representations”) and (ii) the Specified Representations (as defined below) and (b) the terms of the definitive documentation for each Facility shall be in a form such that such Facility is available on the Closing Date if the Funding Conditions are satisfied or waived (it being understood that (I) with respect to any Collateral of the Company and its subsidiaries (other than Atlas and its subsidiaries), to the extent any such Collateral (other than to the extent that a lien on such Collateral may be perfected by (i) the filing of a financing statement under the Uniform Commercial Code

or (ii) the delivery of stock certificates of any material U.S. subsidiary of the Company or any Guarantor (other than Atlas or any subsidiary of Atlas) which are required to be pledged under the Term Sheet) is not or cannot be provided or perfected on the Closing Date after your use of commercially reasonable efforts to do so (consistent with the Transaction Agreement) and (II) with respect to any Collateral of Atlas or any of its subsidiaries, in the case of each of (I) and (II), the provision or perfection of a security interest in such Collateral shall not constitute a condition precedent to the availability of the Facilities and the making of the initial loans and other extensions of credit thereunder on the Closing Date, but shall be required to be provided and perfected within 90 days after the Closing Date (subject to extensions granted by the applicable Administrative Agent, in its reasonable discretion)). For purposes hereof, (x) “Specified Representations” means the representations and warranties of the Borrower and each of the Guarantors set forth in the applicable Term Sheet with respect to (A) their legal existence and power, authorization, due execution and delivery, in each case as they relate to the entering into and performance of the definitive documentation for such Facility by the Borrower and the Guarantors; (B) the enforceability with respect to the Borrower and Guarantors of the definitive documentation for such Facility (subject to customary enforceability exceptions); (C) noncontravention by the definitive documentation for such Facility with respect to the organizational documents of the Borrower and the Guarantors; (D) Federal Reserve margin regulations; (E) Investment Company Act status of the Borrower and the Guarantors; (F) OFAC, FCPA and other applicable sanctions, anti-corruption, anti-money laundering laws; (G) the creation, validity and perfection of the security interests in the Collateral (subject in all respects to customary permitted liens and the limitations set forth above in this paragraph), (H) the PATRIOT Act, and (I) solvency as of the Satisfaction Date of the Company and its subsidiaries (including Atlas and its subsidiaries) on a consolidated basis (with solvency to be defined in a manner consistent with the form of solvency certificate attached as Exhibit D) (the “Solvency Specified Representation”). The provisions of this paragraph are referred to as the “Documentation Provision”.

You agree (a) to indemnify and hold harmless the Initial Lender and Lead Arranger and each of their affiliates, and each of the respective officers, directors, employees, members, partners, trustees, advisors, agents and controlling persons of the foregoing and their respective successors and assigns (each, an “indemnified person”), from and against any and all losses, claims, damages and liabilities, and expenses reasonably related thereto, to which any such indemnified person may become subject arising out of or in connection with this Commitment Letter, the Term Sheet, the Fee Letter, the Facilities and the actual or proposed use of the proceeds thereof or any claim, litigation, investigation or proceeding relating to any of the foregoing, regardless of whether any indemnified person is a party thereto (and regardless of whether such matter is initiated by you or by any other person) (any of the foregoing, a “Proceeding”), and to reimburse each indemnified person upon demand for any reasonable and documented out-of-pocket legal or other out-of-pocket expenses incurred in connection with investigating or defending any Proceeding (it being agreed that, notwithstanding the foregoing, you shall not be responsible for the reimbursement of fees, charges and disbursements of more than one firm of counsel for all the indemnified persons and, if deemed reasonably necessary by us, one firm of regulatory counsel and/or one firm of local counsel in each appropriate jurisdiction, in each case for all indemnified persons, except where any indemnified person reasonably believes that an actual or perceived conflict of interest exists affecting such indemnified person and informs you of such conflict, in which case you shall also be responsible for the reimbursement of fees, charges and disbursements of one firm of counsel (and, if deemed reasonably necessary by such indemnified person, one firm of regulatory and/or one firm of local counsel in each appropriate jurisdiction) for such indemnified person); provided that the foregoing indemnity will not, as to any indemnified person, apply to losses, claims, damages, liabilities or related expenses (i) to the extent they are determined by a final, non-appealable judgment of a court of competent jurisdiction to have resulted from the willful misconduct or gross negligence of such indemnified person or any Related Person thereof (as defined below) or a material breach of the agreements set forth herein of such indemnified person or any of its Related Persons or (ii) to the extent resulting from any Proceeding

that does not involve an act or omission of you or any of your affiliates and that is brought by an indemnified person against any other indemnified person, other than claims against the Initial Lender or Lead Arranger in its capacity in fulfilling its role as an agent or arranger or any other similar role under the Facilities; and (b) to reimburse the Initial Lender, the Lead Arranger and each of their affiliates upon demand for all reasonable and documented out-of-pocket expenses (including reasonable fees, charges and disbursements of one firm of outside counsel (and, if deemed reasonably necessary by us, one firm of regulatory counsel and/or one firm of local counsel in each appropriate jurisdiction)) incurred in connection with the Facilities and any related documentation (including this Commitment Letter, the Term Sheet, the Fee Letter and the definitive documentation for the Facilities) or the amendment, modification or waiver of any thereof. No indemnified person shall be liable for any damages arising from the use of Information or other materials obtained through electronic, telecommunications or other information transmission systems, except to the extent any such damages are found by a final, non-appealable judgment of a court of competent jurisdiction to arise from the gross negligence or willful misconduct of such indemnified person or any of its Related Persons. For purposes hereof, a “Related Person” of an indemnified person means (a) any controlling person, controlled affiliate or subsidiary of such indemnified person, (b) the respective directors, officers or employees of such indemnified person or any of its subsidiaries, controlled affiliates or controlling persons, and (c) the respective agents and advisors of such indemnified person or any of its subsidiaries, controlled affiliates or controlling persons (with respect to this clause (c), in each case acting at the direction of such indemnified person or such subsidiaries, controlled affiliates or controlling persons). You acknowledge that the Commitment Parties may receive a benefit, including, without limitation, a discount, credit or other accommodation, from any such counsel based on the fees such counsel may receive on account of their relationship with us, including without limitation, fees paid pursuant hereto. If any amount previously paid to an indemnified person pursuant to this paragraph is subsequently determined to be ineligible for indemnification as a result of a final, non-appealable judgment of a court of competent jurisdiction, such indemnified person shall promptly reimburse such amount to you.

You agree that (i) in no event shall the Lead Arranger, its affiliates and their respective officers, directors, employees, advisors, and agents (each, and including, without limitation, the Lead Arranger, an “Arranger-Related Person”) or you (or any of your subsidiaries or affiliates) have any Liabilities, on any theory of liability, for any special, indirect, consequential or punitive damages arising out of, in connection with, or as a result of, this Commitment Letter, the Fee Letter or any other agreement or instrument contemplated hereby and (ii) no Arranger-Related Person shall have any Liabilities arising from, or be responsible for, the use by others of Information or other materials (including, without limitation, any personal data) obtained through electronic, telecommunications or other information transmission systems, including an electronic platform or otherwise via the internet (except to the extent such damages have resulted from the willful misconduct or gross negligence of any Arranger-Related Person or any of its Related Persons or a material breach by such Arranger-Related Person or any of its Related Persons of the terms of this Commitment Letter, the Fee Letter or any other agreement or instrument contemplated hereby); provided that, nothing in this paragraph shall relieve you of any obligation you may have to indemnify an indemnified person, as and to the extent provided in the immediately preceding paragraph, against any special, indirect, consequential or punitive damages asserted against such indemnified person by a third party. You agree, to the extent permitted by applicable law, to not assert any claims against any Arranger-Related Person with respect to any of the foregoing. As used herein, the term “Liabilities” shall mean any losses, claims (including intraparty claims), demands, damages or liabilities of any kind.

You will not, without the prior written consent of the applicable indemnified person (which shall not be unreasonably withheld or delayed), settle, compromise, consent to the entry of any judgment in or otherwise seek to terminate any Proceeding in respect of which indemnification may be

sought hereunder (whether or not any indemnified person is a party thereto) unless such settlement, compromise, consent or termination (i) includes an unconditional release of such indemnified person from all liability or claims that are the subject matter of such Proceeding and (ii) does not include a statement as to, or an admission of, fault, culpability, or a failure to act by or on behalf of such indemnified person. You will not be liable for any settlement, compromise, consent or termination of any pending or threatened Proceeding effected without your prior written consent (which shall not be unreasonably withheld); provided that the foregoing indemnity will apply to any such settlement, compromise, consent or termination in the event that you were offered the ability to assume the defense of the action that was the subject matter of such settlement, compromise, consent or termination and elected not to assume such defense; and provided, further, that if a Proceeding is settled, compromised, consented to or terminated with your prior written consent or if there is a final judgment in any such Proceeding, you agree to indemnify and hold harmless each indemnified person to the extent and in the manner set forth above.

This Commitment Letter shall not be assignable by you without the prior written consent of the Initial Lender and the Lead Arranger (and any purported assignment without such consent shall be null and void), is intended to be solely for the benefit of the parties hereto and the indemnified persons and is not intended to confer any benefits upon, create any rights in favor of or be enforceable by or at the request of any person other than the parties hereto and the indemnified persons. Except as provided in the seventh paragraph of this Commitment Letter, the Initial Lender may not assign all or any portion of their respective commitments in respect of any Facility hereunder (and any purported assignment without such consent shall be null and void). Any and all obligations of, and services to be provided by, the Initial Lender or Lead Arranger hereunder may be performed, and any and all rights of the Initial Lender or Lead Arranger hereunder may be exercised, by or through its affiliates; provided that the Initial Lender or Lead Arranger shall not be relieved of any of its obligations hereunder in the event any such affiliate shall fail to perform such obligation in accordance with the terms hereof.

This Commitment Letter may not be amended or waived except by an instrument in writing signed by you and us. This Commitment Letter may be executed in any number of counterparts, each of which shall be an original and all of which, when taken together, shall constitute one agreement. Delivery of an executed counterpart of a signature page of this Commitment Letter by facsimile or other electronic transmission shall be effective as delivery of a manually executed counterpart hereof.

THIS COMMITMENT LETTER SHALL BE GOVERNED BY, AND CONSTRUED IN ACCORDANCE WITH, THE LAWS OF THE STATE OF NEW YORK; provided that (a) the accuracy of any Transaction Agreement Representations and whether as a result of a breach thereof you (or any of your affiliates) have the right under the Transaction Agreement to terminate your obligations under the Transaction Agreement or not to consummate the Acquisition as a result of such representations in the Transaction Agreement being inaccurate and (b) whether the Acquisition has been consummated in accordance with the Transaction Agreement, shall be governed by, and construed in accordance with the

With respect to any securities and/or financial instruments so held by any of us, any of our affiliates or any of our or their customers, all rights in respect of such securities and financial instruments, including any voting rights, will be exercised by the holder of the rights, in its sole discretion; other than as expressly set forth herein with respect to our consent to the Amendment.

BofA Securities and/or its affiliates have been retained as the buy-side financial advisor (in such capacity, the “Financial Advisor”) to the Company in connection with the Transaction. You agree to any such retention, and further agree not to assert any claim you might allege based on any actual or potential conflicts of interest that might be asserted to arise or result from, on the one hand, the engagement of the Financial Advisor or from BofA Securities’ and/or its affiliates’ arranging or providing or contemplating arranging or providing financing for a competing bidder and, on the other hand, our relationship with you as described and referred to herein.

The provisions contained herein relating to compensation, expense reimbursement, indemnification, governing law, submission to jurisdiction, waiver of breach of fiduciary duty or alleged breach of fiduciary duty, waiver of jury trial and confidentiality and in the Fee Letter shall remain in full force and effect notwithstanding the termination of this Commitment Letter or the commitment hereunder, and whether or not definitive documentation for any Facility shall be executed (except to the extent a similar provision relating to expense reimbursement and indemnification (covering the parties and matters covered by the analogous provisions of this Commitment Letter) is also in the definitive documentation for such Facility, in which case such provision in the definitive documentation for such Facility shall govern upon execution thereof). The provisions contained herein relating to syndication and information shall remain in full force and effect until the Syndication Date whether or not definitive documentation for any Facility shall be executed.

and the requirements of 31 C.F.R. §1010.230 (the “Beneficial Ownership Regulation”), it and the Lenders are required to obtain, verify and record information that identifies the Borrower and the Guarantors, which information includes the name and address and other information of the Borrower and the Guarantors that will allow the Initial Lender, Lead Arranger and Lenders to identify the Borrower and the Guarantors in accordance with the Patriot Act or the Beneficial Ownership Regulation.

Each of the parties hereto agrees that this Commitment Letter is a binding and enforceable agreement (subject to the effects of bankruptcy, insolvency, fraudulent transfer, fraudulent conveyance, reorganization and other similar laws relating to or affecting creditors’ rights generally and general principles of equity) with respect to the subject matter contained herein, including an agreement to fund or otherwise extend credit under the commitments hereunder subject only to satisfaction of the Funding Conditions and the good faith negotiation of the definitive documentation of the Facilities.

If the foregoing correctly sets forth our agreement, please indicate your acceptance of the terms hereof and of the Term Sheet and the Fee Letter by returning to us an executed counterpart hereof and of the Fee Letter, to the Lead Arranger, in each case not later than 11:59 p.m. New York City time, on April 17, 2022, failing which the Initial Lender’s commitments and the agreements of the Initial Lender and Lead Arranger hereunder will expire at such time. In the event the Closing Date does not occur on or before 11:59 p.m. (New York time), on the End Date (as defined in the Transaction Agreement as in effect on the date hereof), the Initial Lender’s commitments and the agreements of the Commitment Parties hereunder will automatically expire and terminate at such time, without any further action or notice and without any further obligation.

ANNEX I: Pricing

Interest Rates:

Interest will be payable on loans under the Term Loan Facility at the following rates per annum:

(a) in the case of Term SOFR loans, Term SOFR plus the Applicable Margin per annum, and

(b) in the case of Base Rate loans, the Base Rate plus the Applicable Margin per annum.

As used herein:

“Base Rate”means for any day a fluctuating rate per annum equal to the highest of (a) the Federal Funds Rate plus 1/2 of 1%, (b) the rate of interest in effect for such day as publicly announced from time to time by Bank of America as its “prime rate”, (c) the Secured Overnight Financing Rate published on such day by the SOFR Administrator on the Federal Reserve Bank of New York’s website (or any successor source) plus 1.00% and (d) 1.00%. The “prime rate” is a rate set by Bank of America based upon various factors including Bank of America’s costs and desired return, general economic conditions and other factors, and is used as a reference point for pricing some loans, which may be priced at, above, or below such announced rate. Any change in such prime rate announced by Bank of America shall take effect at the opening of business on the day specified in the public announcement of such change. If the Base Rate is being used as an alternate rate of interest hereof, then the Base Rate shall be the greater of clauses (a) and (b) above and shall be determined without reference to clause (c) above.

“Term SOFR” means a forward-looking term rate for SOFR, if any, identified by the SOFR Administrator as reflecting term-based quotations of SOFR that has been selected or recommended by the Relevant Governmental Body, in each case as published on an information service as selected by the Administrative Agent from time to time in its reasonable discretion, plus the SOFR Adjustment. If the rate as so determined would be less than 0.00%, such rate shall be deemed to be 0.00% for purposes of this Agreement.

“Applicable Margin” shall mean a percentage per annum based on the applicable “Pricing Level” set forth in the below pricing grid (the “Pricing Grid”) and determined quarterly based on meeting a Consolidated Net Leverage Ratio.

B-I-1


		Applicable Margin
Pricing Level	Consolidated Net Leverage Ratio	SOFR Margin	Base Rate Margin
1	< 1.50:1.00	1.25%	0.25%
2	≥ 1.50:1.00 but < 2.50:1.00	1.50%	0.50%
3	≥ 2.50:1.00 but < 3.50:1.00	1.75%	0.75%
4	≥ 3.50:1.00 but < 4.00:1.00	2.00%	1.00%
5	≥ 4.00:1.00	2.25%	1.25%

		applicable interest period (or at the end of each three months, in the case of interest periods longer than three months) and upon prepayment, and on Base Rate loans quarterly and upon prepayment. The Borrower may select interest periods of one, three or six months for Term SOFR loans, subject to availability. Interest on Term SOFR loans shall be payable at the end of the selected interest period, but no less frequently than every three months, and on the Maturity Date.

Default Rate:		With respect to overdue principal, the applicable interest rate plus 2.00% per annum and, with respect to any other overdue amount, the interest rate applicable to Base Rate loans under the Facilities plus 2.00% per annum.

Additional Conditions Precedent³

The initial borrowings under each Facility shall be subject to the following conditions precedent:

The Acquisition shall have been consummated, or substantially concurrently with the funding under such Facility, on substantially the terms set forth in the Transaction Agreement without giving effect to any amendments, waivers or consents under the Transaction Agreement by the Company or its applicable subsidiary that (x) are materially adverse to the Lenders in their capacities as such (each, a “Materially Adverse Modification”) and (y) have not been approved by the Lead Arranger (such approval not to be unreasonably withheld, conditioned or delayed) (it being understood and agreed that any change to the definition of “Material Adverse Effect” in the Transaction Agreement shall be deemed to be materially adverse to the Lenders in their capacities as such).

EXHIBIT D: FORM OF SOLVENCY CERTIFICATE

Pursuant to the Credit Agreement⁴, the undersigned hereby certifies, solely in such undersigned’s capacity as [chief financial officer] of Halozyme Therapeutics, Inc. (the “Company”), and not individually, and without any personal liability, as follows:

After giving effect to the consummation of the Transaction, including the making of the Loans under the Credit Agreement on the Closing Date, and after giving effect to the application of the proceeds of such Loans, [she][he] is of the opinion that:

a. The fair value of the assets of the Company and its Subsidiaries, on a consolidated basis, exceeds, on a consolidated basis, their debts and liabilities, subordinated, contingent or otherwise;

b. The present fair saleable value of the property of the Company and its Subsidiaries, on a consolidated basis, is greater than the amount that will be required to pay the probable liability, on a consolidated basis, of their debts and other liabilities, subordinated, contingent or otherwise, as such debts and other liabilities become absolute and matured;

c. The Company and its Subsidiaries, on a consolidated basis, are able to pay their debts and liabilities, subordinated, contingent or otherwise, as such liabilities become absolute and matured; and

d. The Company and its Subsidiaries, on a consolidated basis, are not engaged in, and are not about to engage in, business for which they have unreasonably small capital.

For purposes of this Certificate, the amount of any contingent liability at any time shall be computed as the amount that would reasonably be expected to become an actual and matured liability. Capitalized terms used but not otherwise defined herein shall have the meanings assigned to them in the Credit Agreement.

The undersigned is familiar with the business and financial position of the Company and its Subsidiaries. In reaching the conclusions set forth in this Certificate, the undersigned has made such other investigations and inquiries as the undersigned has deemed appropriate, having taken into account the nature of the particular business anticipated to be conducted by the Company and its Subsidiaries after consummation of the transactions contemplated by the Commitment Letter.
