ARTICLE I

THE MERGER

Section 1.1 The Merger.

(a) Upon the terms and subject to the conditions set forth in this Agreement, and in accordance with the DGCL, at the Effective Time (as defined below) Merger Sub shall be merged with and into the Company. As a result of the Merger, the separate corporate existence of Merger Sub shall cease, and the Company shall continue as the surviving corporation of the Merger (the “Surviving Corporation”). The Merger shall have the effects set forth in the applicable provisions of the DGCL. Without limiting the generality of the foregoing, at the Effective Time, all of the property, rights, privileges, immunities, powers and franchises of the Company and Merger Sub shall vest in the Surviving Corporation, and all of the debts, expenses, liabilities and duties of the Company and Merger Sub shall become the debts, expenses, liabilities and duties of the Surviving Corporation.

In addition, at the Effective Time, the bylaws of the Company shall be amended and restated in their entirety to read identically to the bylaws of Merger Sub as in effect immediately prior to the Effective Time, except that the name of the Surviving Corporation as used therein shall be “ContraVir Research, Inc.” and, as so amended, shall be the bylaws of the Surviving Corporation until thereafter changed or amended as provided therein or by applicable law.

(c) The parties shall take all actions necessary so that the directors of Merger Sub immediately prior to the Effective Time shall, from and after the Effective Time, be the directors of the Surviving Corporation, each to hold office in accordance with the certificate of incorporation and bylaws of the Surviving Corporation until their respective successors shall have been duly elected or appointed and qualified, or until their earlier death, resignation or removal in accordance with the certificate of incorporation and bylaws of the Surviving Corporation. The officers of the Company immediately prior to the Effective Time shall, from and after the Effective Time, be the officers of the Surviving Corporation, each to hold office in accordance with the certificate of incorporation and bylaws of the Surviving Corporation until their respective successors shall have been duly elected or appointed and qualified, or until their earlier death, resignation or removal in accordance with the certificate of incorporation and bylaws of the Surviving Corporation.

(d) After the Effective Time, if the Surviving Corporation shall determine or shall be advised that any deeds, bills of sale, instruments of conveyance, assignments, assurances or any other actions or things are necessary or desirable to vest, perfect or confirm of record or otherwise in the Surviving Corporation its right, title or interest in, to or under any of the rights, properties or assets of either of the Company or Merger Sub acquired or to be acquired by the Surviving Corporation as a result of, or in connection with, the Merger or otherwise to carry out this Agreement, then the officers and directors of the Surviving Corporation shall be authorized to execute and deliver, in the name and on behalf of either the Company or Merger Sub, all such deeds, bills of sale, instruments of conveyance, assignments and assurances and to take and do, in the name and on behalf of each of such corporations or otherwise, all such other actions and things as may be necessary or desirable to vest, perfect or confirm any and all right, title or interest in, to and under such rights, properties or assets in the Surviving Corporation or otherwise to carry out this Agreement.

1.2 Closing and Effective Time. The closing of the Merger (the “Closing”) will take place at 10:00 a.m., local time, on the fifth (5th) Business Day following the satisfaction or waiver of all of the conditions set forth in Article 5 (other than those conditions that by their nature are to be satisfied at the Closing, but subject to the fulfillment or waiver of those conditions at the Closing), at the offices of Sichenzia Ross Friedman Ference LLP, 61 Broadway, 32^nd Floor, New York, New York 10006, unless another time, date or place is agreed to in writing by the parties hereto. The date on which the Closing actually occurs is referred to herein as the “Closing Date”. At the Closing, the Company shall cause an appropriate certificate of merger or other appropriate documents (the “Certificate of Merger”) to be executed, acknowledged and filed with the Secretary of State of the State of Delaware as provided in Section 251 of the DGCL and shall take all such reasonable further actions and make all other filings or recordings required under the DGCL. The Merger shall become effective at the time the Certificate of Merger shall have been duly filed with the Secretary of State of the State of Delaware or such other date and time as is agreed upon by the parties and specified in the Certificate of Merger, such date and time hereinafter referred to as the “Effective Time”.

1.3 Conversion of Securities. At the Effective Time, by virtue of the Merger and without any action on the part of Buyer, Merger Sub, the Company or the holders of any of the following securities:

(a) Conversion of Company Common Stock. Each share of Company Common Stock (a “Share” or collectively, the “Shares”) issued and outstanding immediately prior to the Effective Time, other than Shares to be cancelled in accordance with Section 1.3(b) and other than Dissenting Shares (as defined below), shall be converted into the right to receive the Milestone Payments pursuant to Section 1.5.

(b) Cancellation of Treasury Stock and Buyer-Owned Stock. All Shares that are held in the treasury of the Company or owned of record by any of the Subsidiaries of the Company, and all Shares owned of record by Buyer, Merger Sub or any of their respective wholly-owned Subsidiaries shall be cancelled and shall cease to exist, with no payment being made with respect thereto.

(c) Merger Sub Common Stock. Each share of common stock, par value $0.0001 per share, of Merger Sub issued and outstanding immediately prior to the Effective Time shall be converted into and become one newly and validly issued, fully paid and nonassessable share of common stock of the Surviving Corporation.

The Milestone Payments, if any, to be paid following the conversion of Shares pursuant to Section 1.3(a) are referred to herein as the “Merger Consideration”. At the Effective Time, all of the Shares shall cease to be outstanding, shall be cancelled and shall cease to exist, and each certificate (a “Certificate”) formerly representing any of the Shares (other than Shares to be cancelled in accordance with Section 1.3(b) and other than Dissenting Shares) shall thereafter represent only the right to receive the Merger Consideration, in each case without interest, subject to compliance with the procedures for surrender of such Shares as set forth in Section 1.4(b). Notwithstanding anything in this Agreement to the contrary, if, from the date of this Agreement until the Effective Time, the outstanding shares of Company Common Stock or the securities convertible into or exercisable for shares of Company Common Stock shall have been changed into a different number of shares or a different class by reason of any reclassification, stock split (including a reverse stock split), recapitalization, split-up, combination, exchange of shares, readjustment, or other similar transaction, or a stock dividend or stock distribution thereon shall be declared with a record date within said period, the Merger Consideration and any other similarly dependent items, as the case may be, shall be appropriately adjusted to provide the holders of Shares the same economic effect as contemplated by this Agreement prior to such event.

1.4 Payments at Closing; Surrender of Certificates.

(a) Closing Statement. On or prior to the third business day prior to the Closing Date, Company shall prepare and deliver to Buyer the Closing Statement.

(b) Payments. At or immediately following the Effective Time, Buyer shall deposit or pay, or shall cause to be deposited or paid, the following amounts in immediately available funds: (i) an amount in cash equal to the unpaid Transaction Expenses to be paid according to the instructions in the Closing Statement and (ii) $200,000 to be deposited with the Company to fund an animal study in combination with CPI-431-32 in an animal model reasonably acceptable to the Company.

(b) Certificates. As promptly as practicable after the Effective Time, Buyer shall mail to each holder of record of a Certificate whose Shares were converted into the right to receive the Merger Consideration at the Effective Time pursuant to this Agreement: (i) a letter of transmittal, which shall specify that delivery shall be effected, and risk of loss and title to the Certificates shall pass, only upon delivery of the Certificates to Buyer, and shall otherwise be in such form and have such other provisions as Buyer may reasonably specify and as reasonably approved by the Company prior to the Effective Time, and (ii) instructions for effecting the surrender of the Certificates in exchange for the right to receive the Merger Consideration. Upon surrender of Certificates for cancellation to Buyer or to such agent or agents as may be appointed by Buyer, and upon delivery of a letter of transmittal, duly executed and in proper form, with respect to such Certificates, and such other documents as may reasonably be required by Buyer, the holder of such Certificates shall be entitled to receive in exchange therefor the Merger Consideration into which each Share formerly represented by such Certificates was converted pursuant to Section 1.3(a), and the Certificates so surrendered shall forthwith be cancelled. In the event of a transfer of ownership of Company Common Stock that is not registered in the transfer records of the Company, payment of the Merger Consideration may be made to a Person other than the Person in whose name the Certificate so surrendered is registered, if such Certificate shall be properly endorsed or shall otherwise be in proper form for transfer and the Person requesting such payment shall pay any transfer and other similar Taxes required by reason of the payment of the Merger Consideration to a Person other than the registered holder of the Certificate so surrendered or shall establish to the satisfaction of Buyer that such Taxes either have been paid or are not required to be paid.

(c) Book-Entry Shares. Any holder of non-certificated Shares represented by book-entry (“Book-Entry Shares” and each individually a “Book-Entry Share”), in each case whose Shares were converted into the right to receive the Merger Consideration at the Effective Time pursuant to this Agreement, shall not be required to deliver a Certificate or an executed letter of transmittal to Buyer to receive the Merger Consideration that such holder is entitled to receive pursuant to this Agreement. In lieu thereof, each holder of record of one or more Book-Entry Shares whose Shares were converted into the right to receive the Merger Consideration at the Effective Time pursuant to this Agreement shall, upon receipt by Buyer of an “agent’s message” (or such other evidence, if any, of surrender as Buyer may reasonably request) be entitled to receive in exchange therefor the amount of cash into which each Share formerly represented by such Book-Entry Share was converted pursuant to Section 1.3(a). Payment of the Merger Consideration with respect to Book-Entry Shares shall only be made to the Person in whose name such Book-Entry Shares are registered.

(d) Rights Prior to Surrender. Until surrendered as contemplated by this Section 1.4, each Certificate and each Book-Entry Share shall be deemed at any time after the Effective Time to represent only the right to receive the Merger Consideration into which the Shares formerly represented by such Certificate or Book-Entry Share has been converted pursuant to Section 1.3(a). No interest shall be paid or accrue on any cash payable upon surrender of any Certificate or Book-Entry Share.

(e) Transfer Books; No Further Ownership Rights in Shares. As of the close of business on the date of the Effective Time, the stock transfer books of the Company shall be closed and thereafter there shall be no further registration of transfers of Shares on the records of the Company. The Merger Consideration paid in accordance with the terms of Section 1.3 and Section 1.4 upon conversion of any Shares shall be deemed to have been paid in full satisfaction of all rights pertaining to such Shares. From and after the Effective Time, the holders of Shares outstanding immediately prior to the Effective Time shall cease to have any rights with respect to such Shares except as otherwise provided for herein or by applicable law. If, after the Effective Time, Certificates are presented to the Surviving Corporation for any reason, they shall be cancelled and exchanged as provided in this Agreement.

(d) Termination of Fund; Abandoned Property; No Liability. Stockholders shall be entitled to look only to the Surviving Corporation (subject to abandoned property, escheat or other similar laws) as general creditors thereof with respect to the Merger Consideration payable upon due surrender of their Shares and compliance with the procedures set forth in Section 1.4(b) or Section 1.4(c), as applicable, without interest. Notwithstanding the foregoing, the Surviving Corporation shall not be liable to any Stockholder for Merger Consideration delivered to a public official pursuant to any applicable abandoned property, escheat or similar law.

(e) Lost, Stolen or Destroyed Certificates. In the event that any Certificate shall have been lost, stolen or destroyed, Buyer shall issue in exchange for such lost, stolen or destroyed Certificate, upon the making of an affidavit of that fact by the holder thereof, the Merger Consideration payable or deliverable in respect thereof pursuant to this Agreement; provided, however, that Buyer may, in its reasonable discretion and as a condition precedent to the payment of any such Merger Consideration, require the owner of such lost, stolen or destroyed Certificate to deliver a bond in such sum as Buyer may reasonably direct as indemnity against any claim that may be made against Buyer, Merger Sub or the Surviving Corporation with respect to the Certificate alleged to have been lost, stolen or destroyed.

1.5 Earnouts.

(a)            Milestone Payments. Subject to Section 1.5(d) and Buyer’s Right of Setoff pursuant to Article VII, upon the achievement by or on behalf of Buyer or the Surviving Corporation of the following events (each, a "Milestone Event"), Buyer shall pay to the Stockholders as specified in the Closing Statement the following additional amounts (each a "Milestone Payment"):

(b)            Adjustments to Merger Consideration.

(c)            Notification and Payment by Buyer. Buyer shall promptly notify Stockholder Representative after the date a Milestone Event has been achieved, as determined by the majority of directors of the Buyer Board (the “Date of Achievement”). Within 30 days of notification by Buyer to Stockholder Representative of the realization of a Milestone, Buyer shall pay the corresponding Milestone Payment to the Stockholders according to the Closing Statement, in shares of Buyer Common Stock or in cash by wire transfer of immediately available funds, as applicable, and each as directed by the Stockholder Representative. Buyer shall consult with the Stockholder Representative prior to finalizing payment amounts to individual Stockholders.

(d)            Milestone Payments to Aurinia Pharmaceuticals Inc. The Milestone Payments to be made to the Stockholders shall be offset, in accordance with Section 1.5(d) of the Company Disclosure Schedule, by the milestone payments to be made by Buyer to Aurinia Pharmaceuticals, Inc. pursuant to Sections 4.1, 4.3 and 4.6 of that certain NICAMs Purchase and Sale Agreement, dated February 14, 2014, by and between Ciclofilin Pharmaceuticals Corp. and Aurinia Pharmaceuticals, Inc., as modified by that certain letter agreement, dated May 26, 2016.

1.6 Dissenting Shares. Notwithstanding anything in this Agreement to the contrary, Shares outstanding immediately prior to the Effective Time and held by a holder who is entitled to demand and has properly demanded appraisal for such Shares in accordance with, and who otherwise complies with, Section 262 of the DGCL (such Shares, “Dissenting Shares”) shall not be converted into the right to receive the Merger Consideration as provided in Section 1.3(a), and shall instead represent the right to receive only the payment provided by Section 262 of the DGCL. If any such holder fails to perfect or otherwise waives, withdraws or loses his right to appraisal under Section 262 of the DGCL or other applicable law, then such Dissenting Shares shall be deemed to be Shares that have been converted as of the Effective Time into, and to have become exchangeable solely for, the right to receive the Merger Consideration as provided in Section 1.3(a), without interest. The Company shall give Buyer (i) prompt notice of any written demands for appraisal, attempted withdrawals of such demands, and any other instruments served pursuant to applicable law that are received by the Company relating to the Stockholders’ rights of appraisal, and (ii) the opportunity to participate in and control all negotiations and proceedings with respect to demands for appraisal under the DGCL. The Company shall not, except with the prior written consent of Buyer, voluntarily make any payment with respect to any demands for appraisal, offer to settle or settle any such demands.

1.7 Withholding Rights. Buyer, Merger Sub and the Surviving Corporation, as the case may be, shall be entitled to deduct and withhold or cause to be deducted or withheld from any amount otherwise payable pursuant to this Agreement to any Person such amounts as Buyer, Merger Sub or the Surviving Corporation are required to deduct and withhold with respect to the making of such payment under the Internal Revenue Code of 1986, as amended (the “Code”) or any other provision of applicable law; provided, however, that before any such deduction or withholding is made, Buyer shall provide to the Stockholder Representative written notice of any applicable payor’s intention to make such deduction or withholding, which notice shall set forth, in reasonable detail, the authority, basis and method of calculation for such deduction or withholding, so as to provide the Stockholder Representative with a reasonable opportunity to obtain reduction of or relief from such deduction or withholding from the applicable Governmental Entity, and Buyer shall reasonably cooperate with the Stockholder Representative to obtain such reduction of or relief from such deduction or withholding. Buyer, Merger Sub and the Surviving Corporation, as applicable, shall timely remit to the appropriate Governmental Entity any and all amounts so deducted or withheld. To the extent that amounts are so withheld and remitted to the appropriate Governmental Entity by Buyer, Merger Sub or the Surviving Corporation or their respective Affiliates, such amounts shall be treated for all purposes of this Agreement as having been paid to the Person in respect of whom such deduction and withholding was made by Buyer, Merger Sub or the Surviving Corporation or their respective Affiliates.

(a) The representations and warranties of Company contained in this Agreement shall survive the Closing Date until the twenty-four (24) month anniversary of the Closing Date; provided, however, that (i) the representations and warranties made pursuant to Sections 2.1, 2.3, 2.4 and 2.15 ("Fundamental Representations") shall survive indefinitely, and (ii) the representations and warranties made pursuant to Sections 2.9, 2.10, 2.13 and 2.14 shall survive until the expiration of the relevant statute of limitations plus 60 days. If written notice of a claim has been given prior to the expiration of the applicable representations and warranties by a Buyer Indemnified Party to Company, then the relevant representations and warranties shall survive as to such claim, until such claim has been finally resolved.

Section 7.2 Indemnification. Subject to the terms and conditions of this Article VII: Stockholders, severally and not jointly (in accordance with the Closing Statement) (each, an “Indemnifying Party” and collectively, the “Indemnifying Parties”), shall indemnify and defend each of Buyer and its Affiliates (including the Company) and their respective Representatives (each, an “Indemnified Party” and collectively, the "Indemnified Parties") against, and shall hold each of them harmless from and against, and shall pay and reimburse each of them for, any and all Damages or amounts that are paid in settlement (collectively, the "Indemnification Liabilities") incurred or sustained by, or imposed upon, the Indemnified Parties based upon, arising out of, with respect to or by reason of:

(a) any inaccuracy in or breach of any of the representations or warranties of the Company contained in this Agreement or in any certificate or instrument delivered by or on behalf of the Company pursuant to this Agreement), as of the date such representation or warranty was made or as if such representation or warranty was made on and as of the Closing Date (except for representations and warranties that expressly relate to a specified date, the inaccuracy in or breach of which will be determined with reference to such specified date);

(b) any breach or non-fulfillment of any covenant, agreement or obligation to be performed by the Company pursuant to this Agreement;

(c) any claim made by any Stockholder relating to such Person's rights with respect to the Merger Consideration or Milestone Payments;

(d) any amounts paid to the holders of Dissenting Shares, including any interest required to be paid thereon, that are in excess of what such holders would have received hereunder had such holders not been holders of Dissenting Shares;

(e) Transaction Expenses to the extent not paid at closing from by Buyer pursuant to Section 1.4(b) or any Indebtedness outstanding at closing; or

(f) all Actions, claims or demands incident to any of the foregoing or initiated to enforce the indemnification provisions in this Agreement.

Section 7.3 Limitations on Indemnification.

(a) In no event shall Company or the Stockholders be liable for claims of Damages pursuant to Section 7.2 or otherwise in an amount in excess of 10% of the aggregate of any remaining Milestone Payments which may be paid subsequent to the time of such claim (the “Liability Cap”). Notwithstanding the foregoing, the Liability Cap shall not be applicable to Damages related to claims for breach of any Fundamental Representation.

(b) If an amount has been claimed by an Indemnified Party pursuant to Section 7.2 of this Agreement (whether or not finally determined to be owed by the Stockholders), Buyer may setoff (the “Right of Setoff”) such amounts claimed against subsequent Milestone Payments payable by Buyer after such claim (if required to be paid pursuant to Section 1.5(a)), on a dollar for dollar basis. In the event a claim for indemnification under this Article VII shall have been finally determined, the amount of the related Damages (after taking into account the limitations of Section 7.3(a)) shall be paid solely through the Right of Setoff to the extent not previously setoff. Once a claim is finally determined in accordance with this Agreement, if the Damages relating to such claim are determined to be less than the amount setoff against the Milestone Payment, Parent shall notify the Stockholder Representative. Thereafter, the Stockholder Representative shall prepare a payment allocation schedule showing the portion of such amount to be paid to each Stockholder and deliver such payment allocation schedule to Buyer. Within five (5) Business Days following Buyer’s receipt of such payment allocation schedule, Buyer shall pay, or cause to be paid, to each Stockholder the portion of such amount set forth opposite such Stockholder’s name on such payment allocation schedule in immediately available funds by check or by wire transfer to such bank account or accounts as may be specified on such payment allocation schedule. For avoidance of doubt, Buyer shall not be permitted under this Section 7.3(b) to seek a setoff for Damages against any Milestone Payments if such amounts have been previously paid to the Stockholders.

(c) From and after the Effective Time, the Right of Setoff shall be the sole and exclusive remedy with respect to any breach of any representation, warranty, covenant or agreement, of Company contained in, or any other claims based upon, arising out of, or otherwise in respect of, this Agreement. No current or former stockholder, director, officer, employee, agent, consultant, Affiliate or advisor of Company shall have any liability of any nature to an Indemnified Party with respect to any breach of any representation, warranty, covenant or agreement contained in, or any other claims based upon, arising out of, or otherwise in respect of, this Agreement.

(d) Without limiting the effect of any other limitation contained in this Article VII, the indemnification provided for in Section 7.2 shall not apply except to the extent that the aggregate Damages against which an Indemnified Party would otherwise be entitled to be indemnified under this Article VII exceeds $25,000 (the “Basket”), in which event the Indemnified Party shall, subject to the other limitations contained herein, be entitled to be indemnified only against the portion of such Damages in excess of the Basket; provided, however, the Basket shall not apply to any claims related to a breach of any Fundamental Representation.

(e) For purposes of computing the amount of any Damages incurred by an Indemnified Party under Section 7.2, there shall be deducted an amount equal to the amount of (i) any insurance proceeds actually received or reasonably expected to be received by the Indemnified Party or any of its Affiliates in connection with such Damages or any of the circumstances giving rise thereto (it being understood that the Indemnified Party and any of its Affiliates shall use commercially reasonable efforts to obtain such proceeds) and (ii) any Tax benefit realized by the Indemnified Party or any of its Affiliates in connection with such Damages.

(f) Nothing in this Section 7.3 shall limit, and neither the Liability Cap nor the Basket nor the limitations on the Right of Setoff set forth in Section 7.3(b) shall apply to, any remedy Buyer may have against any Person for actual fraud involving a knowing and intentional misrepresentation of a fact material to the transactions contemplated by this Agreement made with the intent of inducing any other party hereto to enter into this Agreement and upon which such other party has relied (as opposed to any fraud claim based on constructive knowledge, negligent misrepresentation or a similar theory) under applicable tort laws.

Section 7.4 Tax Treatment of Indemnity Payments. Any payments made to any party pursuant to this Article VII shall constitute a purchase price adjustment for Tax purposes and shall be treated as such by Buyer and Stockholders on their Tax Returns to the extent permitted by law.

Section 7.5 Notice of Claim; Third Party Claims.

(a) An Indemnified Party shall give the Indemnifying Party notice of any matter that an Indemnified Party has determined has given or could give rise to a right of indemnification under this Agreement, within five (5) Business Days of such determination, stating the amount of the Indemnification Liabilities, if known, and method of computation thereof, and containing a reference to the provisions of this Agreement in respect of which such right of indemnification is claimed or arises. Within ten (10) Business Days after receiving notice of a claim for indemnification, the Indemnifying Party shall, by written notice to the Indemnified Party, either concede or deny liability for the claim in whole or in part. Any payment shall be made in immediately available funds equal to the amount of such claim so payable. If the Indemnifying Party denies liability in whole or in part or advises that the matters set forth in the notice are, or will be, subject to contest or legal proceedings not yet finally resolved, then the Indemnifying Party shall make no payment (except for the amount of any conceded liability payable as set forth above) until the matter is resolved in accordance with this Agreement.

(b) If an Indemnified Party shall receive notice of any Action, audit, demand or assessment by a third party (each, a "Third Party Claim") against it or which may give rise to a claim for Indemnification Liabilities under this Article VII, within five (5) Business Days after receipt of such claim, the Indemnified Party shall give the Indemnifying Party notice of such Third Party Claim; provided, however, that the failure to provide such notice shall not release the Indemnifying Party from any of its obligations under this Article VII, except to the extent that the Indemnifying Party is materially prejudiced by such failure, and shall not relieve the Indemnifying Party from any other obligation or liability that it may have to any Indemnified Party otherwise than under this Article VII. If within ten (10) Business Days after receiving the notice of the Third Party Claim, the Indemnifying Party (i) gives written notice to the Indemnified Party stating that the Indemnifying Party disputes and intends to defend against such claim, liability or expense at the Indemnifying Party's own cost and expense and (ii) provides assurance reasonably acceptable to such Indemnified Party that such indemnification will be paid fully and promptly if required and such Indemnified Party will not incur cost or expense during the proceeding, then counsel for the defense shall be selected by the Indemnifying Party (subject to the consent of such Indemnified Party, which consent shall not be unreasonably withheld or delayed) and such Indemnifying Party shall not be required to make any payment to the Indemnified Party with respect to such claim, liability or expense as long as the Indemnifying Party is conducting a good faith and diligent defense at its own expense; provided, however, that the assumption of defense of any such matters by the Indemnifying Party shall relate solely to the claim, liability or expense that is subject or potentially subject to indemnification under this Article VII. If the Indemnifying Party assumes such defense in accordance with the preceding sentence, it shall have the right, with the consent of such Indemnified Party, which consent shall not be unreasonably withheld, conditioned or delayed, to settle all indemnifiable matters related to claims by third parties which are susceptible to being settled, provided the Indemnifying Party's obligation to indemnify such Indemnified Party therefor will be fully satisfied only by payment of money by the Indemnifying Party pursuant to a settlement which includes a complete release of such Indemnified Party. The Indemnifying Party shall keep such Indemnified Party reasonably apprised of the status of the claim, liability or expense and any resulting suit, proceeding or enforcement Action, shall furnish such Indemnified Party with all documents and information that such Indemnified Party shall reasonably request and shall consult with such Indemnified Party prior to acting on major matters, including settlement discussions. Notwithstanding anything herein stated, such Indemnified Party shall at all times have the right to fully participate in such defense at its own expense directly or through counsel; provided, however, if the named parties to the Action or proceeding include both the Indemnifying Party and the Indemnified Party and counsel for the Indemnified Party reasonably determines that representation of both parties by the same counsel would be inappropriate under applicable standards of professional conduct, then the reasonable expense of separate counsel for such Indemnified Party shall be paid by the Indemnifying Party, provided that such Indemnifying Party shall be obligated to pay for only one counsel for the Indemnified Party in any jurisdiction. If no such notice of intent to dispute and defend is given by the Indemnifying Party, or if such diligent good faith defense is not being or ceases to be conducted, such Indemnified Party may undertake the defense of (with counsel selected by such Indemnified Party), and shall have the right to compromise or settle such claim, liability or expense (exercising reasonable business judgment) with the consent of the Indemnifying Party. If such claim, liability or expense is one that by its nature cannot be defended solely by the Indemnifying Party, then such Indemnified Party shall make available all information and assistance that the Indemnifying Party may reasonably request and shall cooperate with the Indemnifying Party in such defense.

Section 7.6 Subrogation. To the extent that an Indemnified Party is entitled to and receives indemnification pursuant to this Article VII, the Indemnifying Party shall be entitled to exercise, and shall be subrogated (on a non-recourse basis and without any representation or warranty by the Indemnified Party) to, any rights and remedies (including rights of indemnity, rights of contribution and other rights of recovery) that the Indemnified Party or any of the Indemnified Party’s subsidiaries or other Affiliates may have against any other person with respect to any damages, circumstances or matter to which such indemnification is directly related. The Indemnified Party shall take such actions as the Indemnifying Party may reasonably request for the purpose of enabling the Indemnifying Party to perfect or exercise the right of subrogation of the Indemnifying Party under this Section 7.5. Any payment received in respect of such rights and remedies shall be distributed, first, to the Indemnifying Party in an amount equal to the aggregate payments made by the Indemnifying Party to the Indemnified Party in respect of such indemnification and, second, the balance, if any, to the Indemnified Party.

Section 7.7 Limitation on Damages. Notwithstanding anything to the contrary elsewhere in this Agreement or provided for under any applicable law, (a) no party nor the Stockholders’ Representative, nor any current or former Stockholder or director, officer, employee, consultant, affiliate or advisor of any of the foregoing, shall, in any event, be liable to any other person, either in contract, tort or otherwise, for any special, indirect, consequential, exemplary or punitive damages or any damages associated with any lost profits or lost opportunities of such other person (including loss of future revenue, income or profits, diminution of value or loss of business reputation) relating to the breach or alleged breach hereof, whether or not the possibility of such damages has been disclosed to the other party in advance or could have been reasonably foreseen by such other party; and (b) the Milestone Payment amounts payable by Buyer shall be considered direct damages, and not otherwise special, indirect, or consequential in nature.
