Forward-looking statements convey our current expectations or forecasts of future events. All statements in this prospectus, including those made by the management of the Company, other than statements of historical fact, are forward-looking statements. Examples of forward-looking statements include statements regarding: the Company’s future financial results, operating results, and projected costs; market acceptance of and demand for dermaPACE and our product candidates; management’s plans and objectives for future operations; industry trends; regulatory actions that could adversely affect the price of or demand for our approved products; our intellectual property portfolio; our business, marketing and manufacturing capacity and strategy; estimates regarding our capital requirements, the anticipated timing of the need for additional funds, and our expectations regarding future capital-raising transactions, including through investments by strategic partners for market opportunities, which may include strategic partnerships or licensing agreements, or raising capital through the conversion of outstanding warrants or issuances of securities; product liability claims; economic conditions that could adversely affect the level of demand for our products; timing of clinical studies and eventual U.S. Food and Drug Administration (“FDA”) approval of our products; financial markets; the competitive environment; and our plans to remediate our material weaknesses in our disclosure controls and procedures and our internal control over financial reporting.

Any or all of our forward-looking statements in this prospectus may turn out to be inaccurate. We have based these forward-looking statements largely on our current expectations and projections about future events and financial trends that we believe may affect our financial condition, results of operations, business strategy and financial needs. They may be affected by inaccurate assumptions we might make or by known or unknown risks and uncertainties, including the risks, uncertainties and assumptions described in the section titled “Risk Factors” in this prospectus or any prospectus supplement, and under a similar heading in any other annual, periodic or current report we file with the SEC. In light of these risks, uncertainties and assumptions, the forward-looking events and circumstances discussed in this prospectus may not occur as contemplated, and actual results could differ materially from those anticipated or implied by the forward-looking statements.

We qualify all of the forward-looking statements in this prospectus by these cautionary statements.

You should not unduly rely on these forward-looking statements, which speak only as of the date of this prospectus. Unless required by law, we undertake no obligation to publicly update or revise any forward-looking statements to reflect new information or future events or otherwise. You should read carefully the factors described in the “Risk Factors” section of this prospectus or any prospectus supplement, and under a similar heading in any other annual, periodic or current report we file with the SEC, to better understand the risks and uncertainties inherent in our business and underlying any forward-looking statements.

This prospectus covers the resale from time to time by the selling stockholders of up to 1,929,282,686 shares of our Common Stock. Once the registration statement of which this prospectus is a part is declared effective, shares of Common Stock issued upon the exercise of Warrants or the conversion of Notes will be available for resale in the public market. If the selling stockholders sell significant amounts of our Common Stock following the effectiveness of the registration statement of which this prospectus is a part, the market price of our Common Stock could decline. Further, the perception of these sales could impair our ability to raise additional capital through the sale of our equity securities.

We will not receive any proceeds from the sale of our Common Stock by the selling stockholders in this offering. The selling stockholders will receive all proceeds from the sale of such shares. Consequently, none of the proceeds from such sale by the selling stockholders will be available to us for our use. See “Use of Proceeds.”

All net proceeds from the sale of the shares of Common Stock covered by this prospectus will go to the selling stockholders. We will receive none of the proceeds from the sale of the shares of Common Stock covered by this prospectus by the selling stockholders. We may receive proceeds upon the exercise of outstanding Warrants for shares of Common Stock covered by this prospectus if the Warrants are exercised for cash. If all of such Warrants are exercised for cash in full at their current exercise prices, the proceeds would be approximately $90.5 million. We intend to use the net proceeds of any such Warrant exercises, if any, for working capital purposes. We can make no assurances that any of the Warrants will be exercised, or if exercised, that they will be exercised for cash, the quantity which will be exercised or the period in which they will be exercised.

The shares being sold pursuant to this prospectus were sold by the Company to the selling stockholders as described below.

The 2020 Private Placement Warrants have an exercise price of $0.25 per share and a three-year term. The closing of the 2020 Private Placement occurred on August 6, 2020. The exercise price of the 2020 Private Placement Warrants is subject to adjustment, including if we list our shares of Common Stock on The Nasdaq Capital Market and the exercise price of the 2020 Private Placement Warrants exceeds the Post-Listing Threshold Price (as defined in the 2020 Private Placement Warrants) for the five trading days preceding such listing. We have granted the purchasers indemnification rights with respect to its representations, warranties, covenants and agreements under the 2020 Purchase Agreement.

In connection with the 2020 Purchase Agreement and the HealthTronics Agreement, we agreed to file a registration statement with the SEC no later than sixty (60) days following the closing of the transactions and will maintain the effectiveness of such registration statement until the date upon which the securities acquired pursuant to the 2020 Purchase Agreement and the HealthTronics Agreement cease to be Registerable Securities (as defined in each agreement). The failure on the part of us to satisfy certain deadlines related to registration may subject us to payment of certain monetary penalties.

On June 5, 2020, we entered into a securities purchase agreement with LGH Investments, LLC (“LGH”), pursuant to which we issued to LGH a promissory note in the original principal amount of $1,210,000, LGH Warrants to purchase 1,000,000 shares of Common Stock, and 200,000 restricted shares of Common Stock. The LGH Warrants had an initial exercise price of $0.35 per share and have a term of five years. The exercise price of the LGH Warrants is subject to adjustment, including if we issue or sell shares of Common Stock or Common Stock Equivalents (as defined in the LGH Warrants) for an effective consideration price less than the exercise price of the LGH Warrants. The number of shares subject to the LGH Warrants and the exercise price of the LGH Warrants were subsequently adjusted in accordance with these anti-dilution adjustment terms, resulting in the LGH Warrants being exercisable for 35,000,000 shares of Common Stock at an exercise price of $0.01 per share. As of December 21, 2022,January 31, 2023, LGH Warrants exercisable for 8,600,000 shares of Common Stock remain outstanding. The LGH Warrants may be exercised on a cashless basis if there is no effective registration statement registering the resale of the shares underlying the LGH Warrants at any time after the earlier of the six-month anniversary of the date of the securities purchase agreement and the completion of the then-applicable holding period required by Rule 144 of the Securities Act.

On August 5, 2022, we entered into a Securities Purchase Agreement (the “August 2022 Purchase Agreement”), with the purchasers identified on the signature pages thereto (the “August 2022 Purchasers”) for our sale in a private placement of (i) the Notes in an aggregate principal amount of approximately $16.1 million, consisting of $12.2 million in newly raised capital and $3.8 million in rolled forward accrued expenses and fees, (ii) First Warrants to purchase an additional 404,839,841 shares of Common Stock with an exercise price of $0.067 per share and (iii) Second Warrants to purchase an additional 404,839,841 shares of Common Stock with an exercise price of $0.04 per share. The Notes will be convertible and the Warrants exercisable at such time as our authorized and unissued shares of Common Stock are at a number sufficient to permit the exercise or conversion of all outstanding securities exercisable for, or convertible into, Common Stock. The exercise price of the Warrants is subject to adjustment, including if we issue or sell shares of Common Stock or Share Equivalents (as defined in the Warrants) for an effective consideration price less than the exercise price of the Warrants or if we list our shares of Common Stock on The Nasdaq Capital Market and the average volume weighted average price of such Common Stock for the five trading days preceding such listing is less than $0.04 per share; provided, however, that the exercise price of the Warrants shall never be less than $0.01 per share. The Warrants have a five-year term. The closing of this private placement occurred on August 5, 2022. We received total proceeds of approximately $14.4 million.

The table set forth below lists the selling stockholders and other information regarding the beneficial ownership (as determined under Section 13(d) of the Exchange Act, and the rules and regulations thereunder) of the shares of Common Stock held by each of the selling stockholders as of December 20, 2022.January 31, 2023. The Notes and the Warrants are subject to certain beneficial ownership limitations, which provide that a holder of such securities will not have the right to exercise any portion thereof if such holder, together with its affiliates and any other persons acting as a group together, would beneficially own in excess of 4.99% or 9.99%, as applicable, of the number of shares of Common Stock outstanding immediately after giving effect to such exercise, provided that such holder may increase or decrease such limitation up to a maximum of 9.99% of the number of shares of Common Stock outstanding. In the case of the Warrants, such limitation may only be increased or decreased upon at least 61 days’ prior notice to us.

Unless otherwise indicated, we believe, based on information supplied by the following persons, that the persons named in the table below have sole voting and investment power with respect to all shares of Common Stock that they beneficially own. The registration of the offered shares does not mean that any or all of the selling stockholders will offer or sell any of the shares of Common Stock.

We are registering the resale of shares of Common Stock issuable to the selling stockholders from time to time after the date of this prospectus upon the exercise of Warrants or conversion of Notes. See “Selling Stockholders” for additional information. We will not receive any proceeds from the resale of shares of Common Stock by selling stockholders in this offering. We may receive proceeds upon the exercise of outstanding Warrants for shares of Common Stock covered by this prospectus if the Warrants are exercised for cash. See “Use of Proceeds.”

The selling stockholders may sell all or a portion of the shares of Common Stock held by them and offered hereby from time to time directly or through one or more underwriters, broker-dealers or agents. If the shares of Common Stock are sold through underwriters or broker-dealers, the selling stockholders will be responsible for underwriting discounts or commissions or agent’s commissions. The shares of Common Stock may be sold in one or more transactions at fixed prices, at prevailing market prices at the time of the sale, at varying prices determined at the time of sale or at negotiated prices. These sales may be effected in transactions, which may involve crosses or block transactions, pursuant to one or more of the following methods:

The selling stockholders may also sell shares of Common Stock under Rule 144 promulgated under the Securities Act, if available, rather than under this prospectus. In addition, the selling stockholders may transfer the shares of Common Stock by other means not described in this prospectus. If the selling stockholders effect such transactions by selling shares of Common Stock to or through underwriters, broker-dealers or agents, such underwriters, broker-dealers or agents may receive commissions in the form of discounts, concessions or commissions from the selling stockholders or commissions from purchasers of the shares of Common Stock for whom they may act as agent or to whom they may sell as principal (which discounts, concessions or commissions as to particular underwriters, broker-dealers or agents may be in excess of those customary in the types of transactions involved). In connection with sales of the shares of Common Stock or otherwise, the selling stockholders may enter into hedging transactions with broker-dealers, which may in turn engage in short sales of the shares of Common Stock in the course of hedging in positions they assume. The selling stockholders may also sell shares of Common Stock short and deliver shares of Common Stock covered by this prospectus to close out short positions and to return borrowed shares in connection with such short sales. The selling stockholders may also loan or pledge shares of Common Stock to broker-dealers that in turn may sell such shares.

To the extent required by the Securities Act and the rules and regulations thereunder, the selling stockholders and any broker-dealer participating in the distribution of the shares of Common Stock may be deemed to be “underwriters” within the meaning of the Securities Act, and any commission paid, or any discounts or concessions allowed to, any such broker-dealer may be deemed to be underwriting commissions or discounts under the Securities Act. At the time a particular offering of the shares of Common Stock is made, a prospectus supplement, if required, will be distributed, which will set forth the aggregate amount of shares of Common Stock being offered and the terms of the offering, including the name or names of any broker-dealers or agents, any discounts, commissions and other terms constituting compensation from the selling stockholders and any discounts, commissions or concessions allowed or re-allowed or paid to broker-dealers. Each selling stockholder has informed us that it does not have any written or oral agreement or understanding, directly or indirectly, with any person to distribute the shares of Common Stock in violation of any applicable securities laws.

Under the securities laws of some states, the shares of Common Stock may be sold in such states only through registered or licensed brokers or dealers. In addition, in some states the shares of Common Stock may not be sold unless such shares have been registered or qualified for sale in such state or an exemption from registration or qualification is available and is complied with.

There can be no assurance that any selling stockholder will sell any or all of the shares of Common Stock registered pursuant to the registration statement, of which this prospectus forms a part.

The selling stockholders and any other person participating in such distribution will be subject to applicable provisions of the Exchange Act, and the rules and regulations thereunder, including, without limitation, to the extent applicable, Regulation M of the Exchange Act, which may limit the timing of purchases and sales of any of the shares of Common Stock by the selling stockholders and any other participating person. To the extent applicable, Regulation M may also restrict the ability of any person engaged in the distribution of the shares of Common Stock to engage in market-making activities with respect to the shares of Common Stock. All of the foregoing may affect the marketability of the shares of Common Stock and the ability of any person or entity to engage in market-making activities with respect to the shares of Common Stock.

Once sold under the registration statement, of which this prospectus forms a part, the shares of Common Stock will be freely tradable in the hands of persons other than our affiliates.

The following description of our Common Stock, together with the additional information we include in any applicable prospectus supplements, summarizes the material terms and provisions of our Common Stock that the selling stockholders may offer under this prospectus. It may not contain all the information that is important to you. For the complete terms of our Common Stock, please refer to our Articles of Incorporation, as amended (the “Articles of Incorporation”), and our Bylaws (the “Bylaws”), which are incorporated by reference into the registration statement which includes this prospectus. The Nevada Revised Statutes (the “NRS”) may also affect the terms of our Common Stock. If we so indicate in a prospectus supplement, the terms of any security offered under that prospectus supplement may differ from the terms we describe below.

Our Articles of Incorporation provide for one class of Common Stock. In addition, our Articles of Incorporation authorize shares of undesignated preferred stock, the rights, preferences and privileges of which may be designated from time to time by our board of directors.

As of September 30, 2022, we had 548,737,651 outstanding shares of Common Stock, held by 205 stockholders of record. As of September 30, 2022, there were (i) outstanding warrants (excluding the Warrants issued in November 2022) for the purchase of an aggregate of 1,006,491,000 shares of Common Stock with a weighted average exercise price of $0.08 per share, (ii) outstanding options for the purchase of an aggregate of 21,246,085 shares of Common Stock with a weighted average exercise price of $0.16 per share, and (iii) outstanding convertible promissory notes (excluding the Notes issued in November 2022) convertible into an aggregate of approximately 483,588,000 shares of Common Stock. In addition, as of September 30, 2022, 3,240,615 shares of our Common Stock were available for issuance pursuant to the Amended and Restated 2006 Stock Incentive Plan.

Each holder of shares of our Common Stock is entitled to one vote per share on all matters submitted to a vote of our Common Stockholders. Cumulative voting in the election of directors is not allowed, which means that the holders of more than 50% of the outstanding shares can elect all the directors if they choose to do so and, in such event, the holders of the remaining shares will not be able to elect any directors. The affirmative vote of a plurality of the shares of Common Stock voted at a stockholders meeting where a quorum is present is required to elect directors and to take other corporate actions. Our Articles of Incorporation do not provide for a classified board of directors; all directors of the Company are elected annually.

Subject to provisions of the NRS and to any future rights which may be granted to the holders of any series of our preferred stock, holders of our Common Stock are entitled to receive ratably such dividends, if any, as may be declared by our board of directors out of legally available funds. However, the current policy of our board of directors is to retain earnings, if any, for the operation and expansion of the Company.

Upon liquidation, dissolution or winding-up, the holders of our Common Stock are entitled to share ratably in all of our assets which are legally available for distribution, after payment of or provision for all liabilities and the liquidation preference of any outstanding preferred stock.

The holders of our Common Stock do not have any preemptive, conversion or redemption rights by virtue of their ownership of our Common Stock.

The following is a brief summary of material provisions of the Class E Warrants related to the shares of Common Stock offered for resale and issuable upon the exercise of the Class E Warrants.

The following is a brief summary of material provisions of the 2022 Warrants related to the shares of Common Stock offered for resale and issuable upon the exercise of the 2022 Warrants.

Each 2022 Warrant entitles the holder thereof to purchase beginning at such time as our authorized and unissued shares of Common Stock are at a number sufficient to permit the exercise or conversion of all outstanding securities exercisable for, or convertible into, Common Stock and until such 2022 Warrant’s expiration date shares of our Common Stock at a price of $0.067 per share for the First Warrants or $0.04 per share for the Second Warrants, subject to certain adjustments referred to below. The 2022 Warrants expire on August 5, 2027 or November 14, 2027. Each 2022 Warrant may be exercised at any time in whole or in part at the applicable exercise price until expiration of the 2022 Warrant. No fractional shares will be issued upon the exercise of the 2022 Warrants.

The exercise price and the number of shares of Common Stock purchasable upon the exercise of the 2022 Warrants are subject to adjustment upon the occurrence of certain events, including stock dividends, stock splits, combinations or reclassifications of the Common Stock. Additionally, an adjustment would be made in the case of a reclassification or exchange of Common Stock, consolidation or merger of our Company with or into another corporation (other than a consolidation or merger in which we are the surviving corporation) or sale of all or substantially all of our assets in order to enable holders of the 2022 Warrants to acquire the kind and number of shares of stock or other securities or property receivable in such event by a holder of the number of shares of Common Stock that might otherwise have been purchased upon the exercise of the 2022 Warrant. No adjustment to the number of shares and exercise price of the shares subject to the 2022 Warrants will be made for dividends (other than stock dividends), if any, paid on our Common Stock.

The exercise price of the 2022 Warrants is also subject to adjustment if we issue or sell shares of Common Stock or Share Equivalents (as defined in the 2022 Warrants) for an effective consideration price less than the exercise price of the 2022 Warrants or if the Company lists its shares of Common Stock on The Nasdaq Capital Market and the average volume weighted average price of such Common Stock for the five trading days preceding such listing is less than $0.04 per share; provided, however, that the exercise price of the Warrants shall never be less than $0.01 per share.

The 2022 Warrants may be presented to us for exchange or exercise at any time on or prior to their expiration date, at which time the 2022 Warrants become wholly void and of no value. The 2022 Warrants are transferable, in whole or in part, upon surrender of the 2022 Warrants at the principal office of the Company or its designated agent, together with a written assignment.

The 2022 Warrants do not confer upon holders any voting, dividend or other rights as stockholders of our Company.

The following is a brief summary of material provisions of the Notes related to the shares of Common Stock offered for resale and issuable upon the conversion of the Notes. The Notes contain customary events of default and covenants, including limitations on incurrences of indebtedness and liens.

We promised to pay each holder in cash and/or in shares of Common Stock, at a Conversion Price of $0.04, the Principal as may be advanced in Disbursements, and to pay Interest at a rate of 15% per annum on any outstanding Principal at the applicable Interest rate from the date of the Notes until the Notes are accelerated, converted, redeemed or otherwise.

The Notes mature on August 7, 2023 or November 14, 2023, at which time all Principal and accrued and unpaid Interest shall be payable in cash, shares of our Common Stock or a combination thereof at the holder’s discretion.

At such time as our authorized and unissued shares of Common Stock are at a number sufficient to permit the exercise or conversion of all outstanding securities exercisable for, or convertible into, Common Stock, any holder may convert any portion of the outstanding Principal and accrued and unpaid Interest into shares of our Common Stock at the then effective Conversion Price. If we list our shares of Common Stock on The Nasdaq Capital Market, then, upon the approval of the board of directors, all Principal and accrued and unpaid Interest under this Note shall automatically convert into Common Stock at the then effective Conversion Price.

At our option and upon 30 days’ notice to the holder, the Notes may be redeemed at any time at an amount equal to 125% of the outstanding Principal and accrued and unpaid Interest.

At any time after a holder becomes aware of an Event of Default (as defined in the Notes), the holder may require us to redeem all or any portion of its Note by delivering written notice to us. Each portion of the Note subject to redemption shall be redeemed in cash at a price equal to Principal plus accrued and unpaid Interest calculated from the Event of Default at the default interest rate of 20% per annum (the “Event of Default Redemption Price”). In addition, we are obligated to pay aggregate liquidated damages of $250,000 pro-rata to the holders of the Notes, plus an amount in cash equal to 1% of the Event of Default Redemption Price for each 30-day period during which redemptions fail to be made, with a cap at 5%.

The Conversion Price of the Notes is subject to adjustment, including if we issue or sell shares of Common Stock for a price per share less than the Conversion Price of the Notes or if we list our shares of Common Stock on The Nasdaq Capital Market and the average volume weighted average price of such Common Stock for the five trading days preceding such listing is less than $0.04 per share; provided, however, that the Conversion Price shall never by less than $0.01.

In connection with the issuance of the Notes, on August 5, 2022 and November 14, 2022 we entered into security agreements in favor of each August 2022 Purchaser and each November 2022 Purchaser, respectively, to secure our obligations under the Notes.

Provisions in our Articles of Incorporation and Bylaws may discourage certain types of transactions involving an actual or potential change of control of our Company which might be beneficial to us or our security holders. In addition, Section 78.438 of the Nevada Revised Statutes prohibits a Nevada corporation with 200 or more stockholders of record from engaging in a business combination with an interested stockholder (generally defined as a person which together with its affiliates owns, or within the last two years has owned, 10% of our voting stock) unless the business combination is approved in a prescribed manner. Further, Nevada law contains provisions governing “acquisition of controlling interest” in Sections 78.378 through 78.3793 of the Nevada Revised Statutes. This law provides generally that any person or entity that acquires 20% or more of the outstanding voting shares of a publicly-held Nevada corporation in the secondary public or private market may be denied voting rights with respect to the acquired shares, unless a majority of the disinterested stockholders of the corporation elects to restore such voting rights in whole or in part. The Control Share Acquisition Act provides that a person or entity acquires “control shares” whenever it acquires shares that, but for the operation of the Control Share Acquisition Act, would bring its voting power within any of the following three ranges: 20 to 33-1/3%; 33-1/3% to 50%; or more than 50%. A “control share acquisition” is generally defined as the direct or indirect acquisition of either ownership or voting power associated with issued and outstanding control shares. The stockholders or board of directors of a corporation may elect to exempt the stock of the corporation from the provisions of the Control Share Acquisition Act through adoption of a provision to that effect in the articles of incorporation or bylaws of the corporation. Our articles of incorporation and bylaws do not exempt our Common Stock from the Control Share Acquisition Act. The Control Share Acquisition Act is applicable only to shares of “Issuing Corporations” as defined by the Nevada law. An Issuing Corporation is a Nevada corporation which (i) has 200 or more stockholders, with at least 100 of such stockholders being both stockholders of record and residents of Nevada, and (ii) does business in Nevada directly or through an affiliated corporation. At this time, we do not believe we have 100 stockholders of record that are residents of Nevada and we do not conduct business in Nevada directly. Therefore, the provisions of the Control Share Acquisition Act are believed not to apply to acquisition of our shares and will not until such time as these requirements have been met. At such time as they may apply, the provisions of the Control Share Acquisition Act may discourage companies or persons interested in acquiring a significant interest in or control of us, regardless of whether such acquisition may be in the interest of our stockholders. The existence of the foregoing provisions and other potential anti-takeover measures could limit the price that investors might be willing to pay in the future for shares of our Common Stock. They could also deter potential acquirers of our Company, thereby reducing the likelihood that you could receive a premium for your Common Stock in an acquisition.

As noted above, our Articles of Incorporation permit our board of directors to issue shares of any class or series of preferred stock in the future without stockholder approval and upon such terms as our board of directors may determine. The rights of the holders of Common Stock will be subject to, and may be adversely affected by, the rights of the holders of any class or series of preferred stock that may be issued in the future.

Our Bylaws generally provide that any board vacancy, including a vacancy resulting from an increase in the authorized number of directors, may be filled by a majority of the directors, even if less than a quorum.

Additionally, our Bylaws provide that stockholders must provide timely notice in writing to bring business before an annual meeting of stockholders or to nominate candidates for election as directors at an annual meeting of stockholders. Notice for an annual meeting is timely if our Secretary receives the written notice not less than 50 days nor more than 75 days prior to the meeting; provided, however, that in the event less than 60 days notice or prior public disclosure of the date of the meeting is given or made to stockholders, notice by the stockholder to be timely must be so received not later than the close of business on the tenth day following the

The following table lists the costs and expenses payable by the Company in connection with the sale of the Common Stock covered by this prospectus. All amounts shown are estimates except for the SEC registration fee.

The Nevada General Corporation Law (“NGCL”) provides that a director or officer is not individually liable to the corporation or its stockholders or creditors for any damages as a result of any act or failure to act in his capacity as a director or officer unless (i) such act or omission constituted a breach of his or her fiduciary duties as a director or officer, and (ii) his or her breach of those duties involved intentional misconduct, fraud or a knowing violation of law. Under the NGCL, a corporation may indemnify directors and officers, as well as other employees and individuals, against any threatened, pending or completed action, suit or proceeding, except an action by or in the right of the corporation, by reason of the fact that he or she is or was a director, officer, employee or agent of the corporation so long as such person acted in good faith and in a manner which he or she reasonably believed to be in or not opposed to the best interests of the corporation, and, with respect to any criminal action or proceeding, had no reasonable cause to believe his or her conduct was unlawful. The termination of any action, suit or proceeding by judgment, order, settlement, conviction or upon a plea of nolo contendere or its equivalent, does not, of itself, create a presumption that the person did not act in good faith and in a manner which he or she reasonably believed to be in or not opposed to the best interests of the corporation, or that, with respect to any criminal action or proceeding, he or she had reasonable cause to believe that his or her conduct was unlawful.

The NGCL further provides that indemnification may not be made for any claim as to which such a person has been adjudged by a court of competent jurisdiction, after exhaustion of all appeals therefrom, to be liable to the corporation or for amounts paid in settlement to the corporation, unless and only to the extent that the court in which the action or suit was brought or other court of competent jurisdiction determines upon application that, in view of all the circumstances of the case, the person is fairly and reasonably entitled to indemnity for such expenses as the court deems proper. To the extent that a director, officer, employee or agent of a corporation has been successful on the merits or otherwise in defense of any action, suit or proceeding or in defense of any claim, issue or matter therein, the corporation must indemnify him or her against expenses, including attorney’s fees, actually and reasonably incurred in connection with the defense. The NGCL provides that this is not exclusive of other rights to which those seeking indemnification may be entitled under any bylaw, agreement, vote of stockholders, or disinterested directors or otherwise.

The Bylaws and contractual arrangements with certain of the Company’s directors and officers provide that the Company is required to indemnify its directors and officers to the fullest extent permitted by law. The Bylaws and these contractual arrangements also require the Company to advance expenses incurred by a director or officer in connection with the defense of any proceeding upon receipt of an undertaking by or on behalf of the director or officer to repay the amount if it is ultimately determined by a court of competent jurisdiction that he or she is not entitled to be indemnified by the Company. The Bylaws also permit the Company to purchase and maintain errors and omissions insurance on behalf of any director or officer for any liability arising out of his or her actions in a representative capacity. The Company does not presently maintain any such errors and omissions insurance for the benefit of its directors and officers.

Insofar as indemnification for liabilities arising under the Securities Act may be permitted to directors, officers or persons controlling the Company pursuant to the foregoing provisions, the Company has been informed that, in the opinion of the SEC, such indemnification is against public policy as expressed in the Securities Act and is therefore unenforceable. In the event that a claim for indemnification against such liabilities

In connection with each of the following unregistered sales and issuances of securities, except as otherwise provided below, the Company relied upon the exemption from registration provided by Section 4(a)(2) of the Securities Act of 1933, as amended, for transactions not involving a public offering based in part upon the representations provided by the purchasers.
