HPPI and its Subsidiaries are in compliance with all U.S. federal, state, local and foreign laws and regulations relating to employment and employment practices, terms and conditions of employment and wages and hours.

HPPI and the Subsidiaries maintain a system of internal accounting controls sufficient to provide reasonable assurance that: (i) transactions are executed in accordance with management’s general or specific authorizations, (ii) transactions are recorded as necessary to permit preparation of financial statements in conformity with GAAP and to maintain asset accountability, (iii) access to assets is permitted only in accordance with management’s general or specific authorization, and (iv) the recorded accountability for assets is compared with the existing assets at reasonable intervals and appropriate action is taken with respect to any differences. HPPI and the Subsidiaries have established disclosure controls and procedures (as defined in Exchange Act Rules 13a-15(e) and 15d-15(e)) for HPPI and the Subsidiaries and designed such disclosure controls and procedures to ensure that information required to be disclosed by HPPI in the reports it files or submits under the Exchange Act is recorded, processed, summarized and reported, within the time periods specified in the Commission’s rules and forms. HPPI’s certifying officers have evaluated the effectiveness of the disclosure controls and procedures of HPPI and the Subsidiaries as of the end of the period covered by the most recently filed periodic report under the Exchange Act (such date, the “Evaluation Date”). HPPI presented in its most recently filed periodic report under the Exchange Act the conclusions of the certifying officers about the effectiveness of the disclosure controls and procedures based on their evaluations as of the Evaluation Date. Since the Evaluation Date, there have been no changes in the internal control over financial reporting (as such term is defined in the Exchange Act) of HPPI and its Subsidiaries that have materially affected, or are reasonably likely to materially affect, the internal control over financial reporting of HPPI or its Subsidiaries.

(s) Certain Fees. No brokerage or finder’s fees or commissions are or will be payable by HPPI or any Subsidiary to any broker, financial advisor or consultant, finder, placement agent, investment banker, bank or other Person with respect to the transactions contemplated by the Transaction Documents.

HPPI has not, since August 12, 2013, received notice from any Trading Market on which the Common Stock is or has been listed or quoted to the effect that HPPI is not in compliance with the listing or maintenance requirements of such Trading Market. HPPI is, and has no reason to believe that it will not in the foreseeable future continue to be, in compliance with all such listing and maintenance requirements. The Common Stock is currently eligible for electronic transfer through the Depository Trust Company or another established clearing corporation and HPPI is current in payment of the fees to the Depository Trust Company (or such other established clearing corporation) in connection with such electronic transfer.

(x) Application of Takeover Protections. HPPI and the Board of Directors have taken all necessary action, if any, in order to render inapplicable any control share acquisition, business combination, poison pill (including any distribution under a rights agreement) or other similar anti-takeover provision under HPPI’s amended and restated certificate of incorporation (or similar charter documents) or the laws of the State of Delaware that is or could become applicable to Mayne Pharma as a result of Mayne Pharma and HPPI fulfilling their obligations or exercising their rights under the Transaction Documents, including without limitation as a result of HPPI’s issuance of the Securities and Mayne Pharma’s ownership of the Securities.

(y) Disclosure. All of the disclosures furnished by or on behalf of HPPI to Mayne Pharma regarding HPPI and HPPI’s Subsidiaries, their respective businesses and the transactions contemplated hereby, including the Disclosure Schedules, and all of the representations and warranties of HPPI contained herein, are true and correct and do not contain any untrue statement of a material fact or omit to state any material fact necessary in order to make the statements made therein, in light of the circumstances under which they were made, not misleading. The press releases disseminated by HPPI during the twelve months preceding the

date of this Agreement taken as a whole do not contain any untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary in order to make the statements therein, in light of the circumstances under which they were made and when made, not misleading. HPPI acknowledges and agrees that Mayne Pharma does not make or has not made any representations or warranties with respect to the transactions contemplated by the Transaction Documents other than those specifically set forth in Section 3.2 hereof.

(z) No Integrated Offering. Assuming the accuracy of Mayne Pharma’s representations and warranties set forth in Section 3.2 hereof, neither HPPI, nor any of its Affiliates, nor any Person acting on its or their behalf has, directly or indirectly, made any offers or sales of any security or solicited any offers to buy any security, under circumstances that would cause this offering of the Purchased Securities to be integrated with prior offerings by HPPI for purposes of the Securities Act which would require the registration of any such securities under the Securities Act.

(aa) Solvency. Based on the consolidated financial condition of HPPI as of the Closing Date, and after giving effect to HPPI’s receipt of the Purchase Price as contemplated hereby: (i) the fair saleable value of HPPI’s assets exceeds the amount that will be required to be paid on or in respect of HPPI’s existing debts and other liabilities (including known contingent liabilities) as they mature, (ii) HPPI’s assets do not constitute unreasonably small capital to carry on its business as now conducted and as proposed to be conducted including its capital needs taking into account the particular capital requirements of the business conducted by HPPI, consolidated and projected capital requirements and capital availability thereof, and (iii) the current cash flow of HPPI, together with the proceeds HPPI would receive, were it to liquidate all of its assets, after taking into account all anticipated uses of the cash, would be sufficient to pay all amounts on or in respect of its liabilities when such amounts are required to be paid. HPPI does not intend to incur debts beyond its ability to pay such debts as they mature (taking into account the timing and amounts of cash to be payable on or in respect of its debt). HPPI has no knowledge of any facts or circumstances which lead it to believe that it will file for reorganization or liquidation under the bankruptcy or reorganization laws of any jurisdiction within one year from the Closing Date. Schedule 3.1(aa) sets forth as of the Signing Date all outstanding secured and unsecured Indebtedness of HPPI or any Subsidiary, or for which HPPI or any Subsidiary has commitments.

5.2 Certain Notifications Until Closing.

ARTICLE VI

ADDITIONAL AGREEMENTS

6.1 Transfer Restrictions.

(a) Mayne Pharma acknowledges and agrees that the Securities may only be disposed of in compliance with state and federal securities laws. In connection with any transfer of the Securities other than pursuant to an effective registration statement or Rule 144 or to HPPI or to an Affiliate of Mayne Pharma, HPPI may require the transferor thereof to provide to HPPI an opinion of counsel selected by the transferor and reasonably acceptable to HPPI, the form and substance of which opinion shall be reasonably satisfactory to HPPI, to the effect that such transfer does not require registration of the Securities which are transferred by the transferor under the Securities Act. As a condition of any such transfer, any such transferee shall agree in writing to be bound by the terms of this Agreement and shall have the rights and obligations of Mayne Pharma under this Agreement.

(b) Mayne Pharma agrees to the imprinting, so long as is required by this Section 6.1, of a legend on any of the Securities in the following form:

THIS SECURITY HAS NOT BEEN REGISTERED WITH THE SECURITIES AND EXCHANGE COMMISSION OR THE SECURITIES COMMISSION OF ANY STATE IN RELIANCE UPON AN EXEMPTION FROM REGISTRATION UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE “SECURITIES ACT”), AND, ACCORDINGLY, MAY NOT BE OFFERED OR SOLD EXCEPT PURSUANT TO AN EFFECTIVE REGISTRATION STATEMENT UNDER THE SECURITIES ACT OR

PURSUANT TO AN AVAILABLE EXEMPTION FROM, OR IN A TRANSACTION NOT SUBJECT TO, THE REGISTRATION REQUIREMENTS OF THE SECURITIES ACT AND IN ACCORDANCE WITH APPLICABLE STATE SECURITIES LAWS AS EVIDENCED BY A LEGAL OPINION OF COUNSEL TO THE TRANSFEROR TO SUCH EFFECT, THE SUBSTANCE OF WHICH SHALL BE REASONABLY ACCEPTABLE TO THE COMPANY.

(c) Certificates evidencing the Shares and the Warrant Shares shall not be required to contain any legend (including the legend set forth in Section 6.1(b) hereof): (i) while a registration statement covering the resale of such security is effective under the Securities Act or (ii) following or in connection with any sale of the Shares or the Warrant Shares pursuant to Rule 144. HPPI shall cause (at HPPI’s cost) its counsel to issue a legal opinion to the Transfer Agent promptly after the occurrence of either of the foregoing if required by the Transfer Agent to effect the removal of the legend hereunder. Certificates for the Shares and the Warrant Shares subject to legend removal hereunder shall upon Mayne Pharma’s request be transmitted by the Transfer Agent to Mayne Pharma by crediting the account of Mayne Pharma’s prime broker with the Depository Trust Company system as directed by Mayne Pharma.

(d) Mayne Pharma agrees with HPPI that Mayne Pharma will sell the Securities pursuant to either the registration requirements of the Securities Act, including any applicable prospectus delivery requirements, or an exemption therefrom, and that if any of the Securities are sold pursuant to a registration statement, they will be sold in compliance with the plan of distribution set forth therein, and acknowledges that the removal of the restrictive legend from certificates representing the Shares and the Warrant Shares as set forth in this Section 6.1 is predicated upon HPPI’s reliance upon this understanding.

6.2 Integration. HPPI shall not sell, offer for sale or solicit offers to buy or otherwise negotiate in respect of any security (as defined in Section 2 of the Securities Act) that would be integrated with the offer or sale of any of the Securities in a manner that would require the registration under the Securities Act of the sale of any of the Securities or that would be integrated with the offer or sale of any of the Securities for purposes of the rules and regulations of any Trading Market such that it would require shareholder approval prior to the closing of such other transaction unless shareholder approval is obtained before the closing of such subsequent transaction.

6.3 Securities Laws Disclosure; Publicity. HPPI shall (a) by 9:30 a.m. (New York City time) on the Trading Day immediately following the Signing Date, issue a press release disclosing the material terms of the transactions contemplated hereby, and (b) file a Current Report on Form 8-K, including the Transaction Documents as exhibits thereto, with the Commission within the time required by the Exchange Act. HPPI and Mayne Pharma shall consult with each other in issuing any other press releases with respect to the transactions contemplated hereby, and neither HPPI nor Mayne Pharma shall issue any such press release nor otherwise make any such public statement without the prior consent of HPPI, with respect to any press release of Mayne Pharma, or without the prior consent of Mayne Pharma, with respect to any press release of HPPI, which consent shall not unreasonably be withheld or delayed, except if such disclosure is required by law or any Trading Market, in which case the disclosing party shall promptly provide the other party with prior notice of such public statement or communication.

6.4 Shareholder Rights Plan. No claim will be made or enforced by HPPI or, with the consent of HPPI, any other Person, that Mayne Pharma is an “acquiring person” under any control share acquisition, business combination, poison pill (including any distribution under a rights agreement) or similar anti-takeover plan or arrangement in effect or hereafter adopted by HPPI, or that Mayne Pharma could be deemed to trigger the provisions of any such plan or arrangement, by virtue of receiving any of the Securities under the Transaction Documents or under any other agreement between HPPI and Mayne Pharma.

6.5 Indemnification of Mayne Pharma, Etc. Subject to the provisions of this Section 6.5, HPPI will indemnify and hold Mayne Pharma and Mayne Pharma’s directors, officers, shareholders, members, partners, employees and agents (and any other Person with a functionally equivalent role of a Person holding such titles notwithstanding a lack of such title or any other title), each Person who controls (within the meaning of Section 15 of the Securities Act and Section 20 of the Exchange Act) Mayne Pharma, and the directors, officers, shareholders, agents, members, partners or employees (and any other Person with a functionally equivalent role of a Person holding such titles notwithstanding a lack of such title or any other title) of such controlling Persons (each, a “Mayne Pharma Party” and collectively, the “Mayne Pharma Parties”) harmless from and against any and all losses, liabilities, obligations, claims, contingencies, damages, costs and expenses, including all judgments, amounts paid in settlements, court costs and reasonable attorneys’ fees and costs of investigation that any Mayne Pharma Party may suffer or incur as a result of or relating to (a) any breach of any of the representations, warranties, covenants or agreements made by HPPI in this Agreement or in any other Transaction Document or (b) any Action instituted against the Mayne Pharma Parties in any capacity, or any of them or their respective Affiliates with respect to any of the transactions contemplated by the Transaction Documents (unless such Action is based upon a breach of such Mayne Pharma Party’s representations, warranties or covenants under the Transaction Documents or any violations by such Mayne Pharma Party of state or federal securities laws or any conduct by such Mayne Pharma Party which constitutes fraud, gross negligence, willful misconduct or malfeasance). If any Action shall be brought against any Mayne Pharma Party in respect of which indemnity may be sought pursuant to this Agreement, such Mayne Pharma Party shall promptly notify HPPI in writing, and HPPI shall have the right to assume the defense thereof with counsel of its own choosing reasonably acceptable to such Mayne Pharma Party. Any such Mayne Pharma Party shall have the right to employ separate counsel in any such Action and participate in the defense thereof, but the fees and expenses of such counsel shall be at the expense of such Mayne Pharma Party except to the extent that (i) the employment thereof has been specifically authorized by HPPI in writing, (ii) HPPI has failed after a reasonable period of time to assume such defense and to employ counsel or (iii) in such Action there is, in the reasonable opinion of counsel, a material conflict on any material issue between the position of HPPI and the position of such Mayne Pharma Party, in which case HPPI shall be responsible for the reasonable fees and expenses of no more than one such separate counsel of such Mayne Pharma Party. HPPI will not be liable to any Mayne Pharma Party under this Agreement (y) for any settlement by a Mayne Pharma Party effected without HPPI’s prior written consent, which shall not be unreasonably withheld or delayed; or (z) to the extent, but only to the extent that a loss, claim, damage or liability is attributable to any Mayne Pharma Party’s breach of any of the

representations, warranties, covenants or agreements made by such Mayne Pharma Party in this Agreement or in the other Transaction Documents. The indemnification required by this Section 6.5 shall be made by periodic payments of the amount thereof during the course of the investigation or defense, as and when bills are received or are incurred. The indemnity agreements contained herein shall be in addition to any cause of Action or similar right of any Mayne Pharma Party against HPPI or others and any liabilities HPPI may be subject to pursuant to law.

6.6 Use of Proceeds. HPPI shall use the net proceeds from the Purchase (a) to conduct the Basal Cell Carcinoma Nevus Syndrome clinical program for the Product, (b) to prepare the appropriate regulatory documents to progress an FDA new drug application for the Product, (c) to develop and progress the intellectual property strategy of HPPI, (d) to conduct any additional clinical programs recommended by the JDC and approved by the Board of Directors, and (e) for working capital purposes, and shall not use such proceeds: (i) for the satisfaction of any portion of the Company’s debt (other than payment of trade payables in the ordinary course of the Company’s business and prior practices), (ii) for the redemption of any Common Stock or Common Stock Equivalents, (iii) for the settlement of any outstanding litigation, or (iv) in violation of FCPA or OFAC regulations.

6.7 Reservation of Common Stock. From the Closing Date until the date on which the Warrant has been fully exercised, HPPI shall at all times have reserved for issuance, free of Liens, a sufficient number of shares of authorized and unissued Common Stock for the purpose of enabling HPPI to issue all of the Warrant Shares.

6.8 Listing of Common Stock. HPPI agrees, if HPPI applies to have the Common Stock traded on any Trading Market other than its current Trading Market, it will then include in such application all of the Shares and the Warrant Shares, and will take such other action as is necessary to cause all of the Shares and the Warrant Shares to be listed or quoted on such other Trading Market as promptly as possible. For so long as the Common Stock trades or is listed for quotation on a Trading Market, HPPI agrees to use its commercially reasonable efforts to maintain the eligibility of the Common Stock for electronic transfer through the Depository Trust Company or another established clearing corporation, including, without limitation, by timely payment of fees to the Depository Trust Company or such other established clearing corporation in connection with such electronic transfer.

6.9 Certain Transactions and Confidentiality. Mayne Pharma covenants that neither it, nor any Affiliate acting on its behalf or pursuant to any understanding with it will execute any purchases or sales of any of HPPI’s securities during the period commencing with the Signing Date and ending at such time that the transactions contemplated by this Agreement are first publicly announced pursuant to the initial press release as described in Section 6.3 hereof. Mayne Pharma covenants that until such time as the transactions contemplated by this Agreement are publicly disclosed by HPPI pursuant to the initial press release as described in Section 6.3 hereof, Mayne Pharma will maintain the confidentiality of the existence and terms of this transaction and the information included in the Transaction Documents and the Disclosure Schedules. Notwithstanding the foregoing, and notwithstanding anything contained in this Agreement to the contrary, HPPI expressly acknowledges and agrees that (i) Mayne Pharma makes no representation, warranty or covenant hereby that it will not engage in effecting

transactions in any securities of HPPI after the time that the transactions contemplated by this Agreement are first publicly announced pursuant to the initial press release as described in Section 6.3 hereof, (ii) Mayne Pharma shall not be restricted or prohibited from effecting any transactions in any securities of HPPI in accordance with applicable securities laws from and after the time that the transactions contemplated by this Agreement are first publicly announced pursuant to the initial press release as described in Section 6.3 hereof, and (iii) Mayne Pharma shall have no duty of confidentiality to HPPI or its Subsidiaries after the issuance of the initial press release as described in Section 6.3 hereof.

6.10 Acknowledgment of Dilution.

HPPI further acknowledges that its obligations under the Transaction Documents, including, without limitation, its obligation to issue the Shares and the Warrant Shares pursuant to the Transaction Documents, are unconditional and absolute and not subject to any right of set off, counterclaim, delay or reduction, regardless of the effect of any such dilution or any claim HPPI may have against Mayne Pharma and regardless of the dilutive effect that such issuance may have on the ownership of the other stockholders of HPPI.

6.11 Equity Incentive Plan. HPPI covenants and agrees that, without the prior written consent of Mayne Pharma, the shares authorized to be issued, granted or purchased under the EIP shall not exceed 32,583,475 shares of Common Stock.

7.6 Headings. The headings herein are for convenience only, do not constitute a part of this Agreement and shall not be deemed to limit or affect any of the provisions hereof.

7.7 Successors and Assigns. This Agreement shall be binding upon and inure to the benefit of the parties and their successors and permitted assigns.

7.9 Governing Law. Each of the Transaction Documents and any dispute arising thereunder shall be governed by and construed and enforced in accordance with the laws of the State of Delaware applicable to agreements made and to be performed wholly within such State, without regard to its conflict of law rules.

7.10 Arbitration of Claims.

7.11 Survival. The representations, warranties and covenants contained herein shall survive the Closing and the delivery of the Purchased Securities.

7.12 Execution. This Agreement may be executed in two or more counterparts, all of which when taken together shall be considered one and the same agreement and shall become effective when counterparts have been signed by each party and delivered to each other party, it being understood that the parties need not sign the same counterpart. In the event that any signature is delivered by facsimile transmission or by e-mail delivery of a “.pdf” format data file, such signature shall create a valid and binding obligation of the party executing (or on whose behalf such signature is executed) with the same force and effect as if such facsimile or “.pdf” signature page were an original thereof.

7.13 Severability. If any term, provision, covenant or restriction of this Agreement or any of the Transaction Documents is held by a court of competent jurisdiction to be invalid, illegal, void or unenforceable, the remainder of the terms, provisions, covenants and restrictions set forth herein shall remain in full force and effect and shall in no way be affected, impaired or invalidated, and the parties hereto shall use their commercially reasonable efforts to find and employ an alternative means to achieve the same or substantially the same result as that contemplated by such term, provision, covenant or restriction. It is hereby stipulated and declared to be the intention of the parties that they would have executed the remaining terms, provisions, covenants and restrictions without including any of such that may be hereafter declared invalid, illegal, void or unenforceable.

7.14 Rescission and Withdrawal Right. Notwithstanding anything to the contrary contained in (and without limiting any similar provisions of) any of the other Transaction Documents, whenever Mayne Pharma exercises a right, election, demand or option under a Transaction Document and HPPI does not timely perform its related obligations within the periods therein provided, then Mayne Pharma may rescind or withdraw, in its sole discretion from time to time upon written notice to HPPI, any relevant notice, demand or election in whole or in part without prejudice to its future Actions and rights; provided, however, that in the case of a rescission of an exercise of the Warrant or any part thereof, Mayne Pharma shall be required to return any shares of Common Stock subject to any such rescinded exercise notice concurrently with the return to Mayne Pharma of the aggregate exercise price paid to HPPI for such shares and the restoration of Mayne Pharma’s right to acquire such shares pursuant to the Warrant (including, issuance of a replacement warrant certificate evidencing such restored right).

7.15 Replacement of Securities. If any certificate or instrument evidencing any of the Securities is mutilated, lost, stolen or destroyed, HPPI shall issue or cause to be issued in exchange and substitution for and upon cancellation thereof (in the case of mutilation), or in lieu of and substitution therefor, a new certificate or instrument, but only upon receipt of evidence reasonably satisfactory to HPPI of such loss, theft or destruction. The applicant for a new certificate or instrument under such circumstances shall also pay any reasonable third-party costs (including customary indemnity) associated with the issuance of such replacement securities.

7.16 Remedies. In addition to being entitled to exercise all rights provided herein or granted by law, including recovery of damages, each of Mayne Pharma and HPPI will be entitled to specific performance under the Transaction Documents. The parties agree that monetary damages may not be adequate compensation for any loss incurred by reason of any breach of obligations contained in the Transaction Documents and hereby agree to waive and not to assert in any Action for specific performance of any such obligation the defense that a remedy at law would be adequate.

7.17 Payment Set Aside. To the extent that HPPI makes a payment or payments to Mayne Pharma pursuant to any Transaction Document or Mayne Pharma enforces or exercises its rights thereunder, and such payment or payments or the proceeds of such enforcement or exercise or any part thereof are subsequently invalidated, declared to be fraudulent or preferential, set aside, recovered from, disgorged by or are required to be refunded, repaid or otherwise restored to HPPI, a trustee, receiver or any other Person under any law (including, without limitation, any bankruptcy law, state or federal law, common law or equitable cause of Action), then to the extent of any such restoration the obligation or part thereof originally intended to be satisfied shall be revived and continued in full force and effect as if such payment had not been made or such enforcement or setoff had not occurred.

7.18 Saturdays, Sundays, Holidays, etc. If the last or appointed day for the taking of any action or the expiration of any right required or granted herein shall not be a Business Day, then such action may be taken or such right may be exercised on the next succeeding Business Day.

7.19 Construction. The parties agree that each of them and/or their respective counsel have reviewed and had an opportunity to revise the Transaction Documents and, therefore, the
