(vi) ########*.

(vii) ########*.

(c) If, pursuant to Section 1.2(a), the number of shares of Retrophin Common Stock a Seller would be entitled to receive results in receipt of fractional shares, the aggregate number of shares of Retrophin Common Stock the Seller is entitled to purchase will be rounded up to the nearest whole number.

(d) If, at any time that Purchaser Shares are issuable to the Sellers hereunder, (i) adequate current public information with respect to Buyer is not available (as determined by Rule 144(c), promulgated under the Securities Act, or any successor rule thereto) and does not become so available within thirty days after the date such Purchaser Shares first become issuable, or (ii) Buyer is not then subject to the reporting requirements of section 13 or 15(d) of the Exchange Act, Buyer shall, instead of issuing such Purchaser Shares, issue to each Seller one half (1/2) of the number of Purchaser Shares required to be issued under this Agreement and pay each Seller, in cash, the other one half (1/2) of the dollar amount that would otherwise be issued in Purchaser Shares. By way of an example, if on the date that issuance of Purchaser Shares is due under Section 1(a)(iii) hereof, either of the conditions set forth in the first sentence of this Section 1(a)(d) is met, then (1) Buyer shall issue to each Seller his, her or its Pro Rata Share of a number of shares of Retrophin Common Stock determined by dividing ########* by ########* and (2) Buyer shall pay the Sellers cash in the amount of ########* according to each Seller’s Pro Rata Share.

Buyer shall provide prompt written notice to each Seller of any such adjustment, including the total number, class, and kind of shares issuable and showing in reasonable detail the facts on which that adjustment is based. All adjustments under this Section 1.2(e) shall be made cumulatively and successively whenever an event requiring any such adjustment occurs.

(f) Notwithstanding anything to the contrary herein, in the event of any Sale or Asset Transfer of Buyer following the Closing Date (any such transaction a “Change in Control”), payment of the Closing Cash Consideration and Post-Closing Cash Consideration, to the extent not already paid to the Sellers, the issuances of Retrophin Common Stock issuable pursuant to ########*, to the extent not already issued hereunder, and the payment of any cash consideration required under Section 1(a)(i) and Section 1(a)(ii), after giving effect to the adjustments required by Section 1(d) and to the extent not already paid (collectively the “Time-based Payments”), shall be accelerated and shall be due and payable or issuable, as the case may be, to the Sellers as of immediately prior to the effective date of such Change in Control. For the purposes of this Section 1.2(f), “Sale” shall mean (A) any consolidation or merger of Buyer with or into any other corporation or other entity or person (other than the Company), or any other corporate reorganization, other than any such consolidation, merger or reorganization in which the stockholders of Buyer immediately prior to such consolidation, merger or reorganization, continue to hold at least a majority of the voting power of the surviving entity in substantially the same proportions (or, if the surviving entity is a wholly owned subsidiary, its parent) immediately after such consolidation, merger or reorganization; and “Asset Transfer” shall mean the sale, lease, exclusive license or other disposition (except pursuant to this agreement) of all or substantially all of the Assets of the Company as of the Closing Date, unless the acquirer of such assets expressly undertakes to perform the obligations of the Buyer hereunder. Notwithstanding anything to the contrary herein, in no event shall any Sale or Asset Transfer in which Xxxxxx Xxxxxxx serves as principal executive officer of the acquiring or surviving entity immediately after the consummation thereof constitute a Change of Control.

(ii) The aggregate Adverse Consequences for which the Buyer Indemnitees shall be entitled to seek and obtain indemnification pursuant to Section 8.1 shall not exceed the amount that is ########* (other than with respect to claims for any breach or inaccuracy of any representation or warranty that is fraudulent).

____________________

* ######## = Material omitted pursuant to a request for Confidential Treatment and submitted separately to the Commission on the date of submission of this Current Report on Form 8-K.

(b) The limit set forth in Section 8.3(a)(ii) hereof, shall not apply to any breach by any of Seller of any of the Fundamental Representations or any Adverse Consequences arising out of or relating to fraud or willful misrepresentation, or willful breach. For the sole purpose of determining the amount of Adverse Consequences (and not for determining whether or not any breaches of representations or warranties have occurred), the representations and warranties of the Company and Sellers shall not be deemed qualified by any references to materiality, knowledge or material adverse effect.

(c) The indemnification obligations in Section 8.1(a), (b) and Section 8.2(a) and (b) shall terminate when the respective representation and warranty or covenant expires, as set forth in Article 6 above. With respect to any Claim Notice or Indemnity Notice delivered within the survival periods set forth in Article 6 above, the representations and warranties that are the subject of such indemnification claim shall survive with respect to such claim until such claim is finally resolved.

(d) Notwithstanding the foregoing, the total amount of the payments that Sellers can be required to make under or in connection with this Agreement (including all indemnification payments required to be made to Buyer and all expenses incurred by the Agent in accordance with Article 2) shall be limited in the aggregate to a maximum of ########*, and the Sellers’ cumulative liability shall in no event exceed such amount.

(e) Without limiting the foregoing, any indemnification payments required to be made by any Seller hereunder, other than indemnification payments with respect to Adverse Consequences arising out of any breach by the Company or Sellers of a Fundamental Representation, shall be made exclusively from the portion of the Purchase Price not yet paid to Sellers hereunder, pursuant to the set off provisions set forth in Section 8.5 and Buyer shall have no recourse against any Seller or any of Seller’s affiliates, or against any of the assets of the Sellers or any of the Seller’s affiliates, in connection with any indemnification claim or any other claim of any nature.

8.4. Method of Asserting Claims, etc.

Adverse Consequences shall include the respective damages from and against which the Buyer, the Company and their subsidiaries and affiliates and their respective officers, directors, shareholders, representatives, agents and attorneys (the “Buyer Indemnitees”) or the Sellers and his representatives, agents and attorneys (the “Sellers Indemnitees”), as the case may be, are indemnified as the context requires. The Person claiming indemnification hereunder, whether a Buyer Indemnitee or Sellers Indemnitee, is sometimes referred to as the “Indemnified Party” and the party against whom such claims are asserted hereunder is sometimes referred to as the “Indemnifying Party”. All claims for indemnification by an Indemnified Party under Section 8.1 or Section 8.2 hereof, as the case may be, shall be asserted and resolved as follows:

____________________

* ######## = Material omitted pursuant to a request for Confidential Treatment and submitted separately to the Commission on the date of submission of this Current Report on Form 8-K.

(a) If any claim or demand for which an Indemnifying Party would be liable for Adverse Consequence to an Indemnified Party hereunder is overtly asserted against or sought to be collected from such Indemnified Party by a third party (a “Third Party Claim”), such Indemnified Party shall with reasonable promptness (but in no event later than five days after the Third Party Claim is so asserted or sought against the Indemnified Party) notify in writing the Indemnifying Party of such Third Party Claim enclosing a copy of all papers served, if any, and specifying the nature of and specific basis for such Third Party Claim and the amount or the estimated amount thereof to the extent then feasible, which estimate shall not be conclusive of the final amount of such Third Party Claim (the “Claim Notice”). For this purpose the commencement of any audit or other investigation respecting Taxes shall constitute a Third Party Claim. Notwithstanding the foregoing, failure to so provide a Claim Notice as provided above shall not relieve the Indemnifying Party from its obligation to indemnify the Indemnified Party with respect to any such Third Party Claim except to the extent that a failure to so notify the Indemnifying Party in reasonably sufficient time prejudices the Indemnifying Party’s ability to defend against the Third Party Claim. The Indemnifying Party shall have thirty days from delivery of the Claim Notice (the “Notice Period”) to notify the Indemnified Party (i) whether or not the Indemnifying Party disputes the liability of the Indemnifying Party to the Indemnified Party hereunder with respect to such Third Party Claim and (ii) whether or not the Indemnifying Party desires, at the sole cost and expense of the Indemnifying Party, to defend the Indemnified Party against such Third Party Claim.

(b) If the Indemnifying Party notifies the Indemnified Party within the Notice Period that the Indemnifying Party does not dispute its liability to the Indemnified Party and that the Indemnifying Party desires to defend the Indemnified Party with respect to the Third Party Claim pursuant to this Article 7, then the Indemnifying Party shall have the right to defend, at its sole cost and expense, such Third Party Claim by all appropriate proceedings, which proceedings shall be diligently prosecuted by the Indemnifying Party to a final conclusion or settled at the discretion of the Indemnifying Party (but only if the Indemnifying Party is liable hereunder to the Indemnified Party for the full amount of, and all obligations under, such settlement; otherwise, no such settlement shall be agreed to without the prior written consent of the Indemnified Party, which consent will not be unreasonably withheld). If the Indemnifying Party is liable hereunder to the Indemnified Party for the full amount of such Third Party Claim, the Indemnifying Party shall have full control of such defense and proceedings, including any compromise or settlement thereof; provided, however, that the Indemnified Party is hereby authorized, at the sole cost and expense of the Indemnifying Party (but only if the Indemnified Party is actually entitled to indemnification hereunder or if the Indemnifying Party assumes the defense with respect to the Third Party Claim as permitted hereunder), to file during the Notice Period any motion, answer or other pleadings which the Indemnified Party shall deem necessary or appropriate to protect its interests or those of the Indemnifying Party and not prejudicial to the Indemnifying Party (it being understood and agreed that if an Indemnified Party takes any such action which is prejudicial and conclusively causes a final adjudication which is adverse to the Indemnifying Party, the Indemnifying Party shall be relieved of its obligations hereunder with respect to such Third Party Claim); and provided further that if requested by the Indemnifying Party, the Indemnified Party agrees, at the sole cost and expense of the Indemnifying Party, to cooperate with the Indemnifying Party and its counsel in contesting any Third Party Claim which the Indemnifying Party elects to contest, or, if appropriate and related to the Third Party Claim in question, in making any counterclaim against the Person asserting the Third Party Claim, or any cross-complaint against any Person. The Indemnified Party may participate in, but not control (except if the Indemnifying Party is not allegedly liable hereunder to the Indemnified Party for the full amount of such Third Party Claim, in which case whichever of the Indemnifying Party or the Indemnified Party is allegedly liable for the largest amount of Adverse Consequence with respect to the Third Party Claim shall control), any defense or settlement of any Third Party Claim with respect to which the Indemnifying Party is participating pursuant to this Section 8.4(b), and except as provided in the preceding sentence, the Indemnified Party shall bear its own costs and expenses with respect to such participation.

(c) If the Indemnifying Party fails to notify the Indemnified Party within the Notice Period that the Indemnifying Party does not dispute its liability to the Indemnified Party and that the Indemnifying Party desires to defend the Indemnified Party pursuant to this Article 7, then the Indemnified Party shall have the right to defend, at the sole cost and expense of the Indemnifying Party, the Third Party Claim by all appropriate proceedings, which proceedings shall be promptly and vigorously prosecuted by the Indemnified Party to a final conclusion or settled. The Indemnified Party shall have full control of such defense and proceedings, including any compromise or settlement thereof; provided, however, that if requested by the Indemnified Party, the Indemnifying Party agrees, at the sole cost and expense of the Indemnifying Party, to cooperate with the Indemnified Party and its counsel in contesting any Third Party Claim which the Indemnified Party is contesting, or, if appropriate and related to the Third Party Claim in question, in making any counterclaim against the Person asserting the Third Party Claim, or any cross-complaint against any Person. Notwithstanding the foregoing provisions of this Section 8.4(c), if the Indemnifying Party has timely notified the Indemnified Party that the Indemnifying Party disputes its liability to the Indemnified Party and if such dispute is resolved in favor of the Indemnifying Party by final, non-appealable order of a court of competent jurisdiction, the Indemnifying Party shall not be required to bear the costs and expenses of the Indemnified Party’s defense pursuant to this Section 8.4(c) or of the Indemnifying Party’s participation therein at the Indemnified Party’s request and the Indemnified Party shall reimburse the Indemnifying Party in full for all costs and expenses of such litigation. The Indemnifying Party may participate in, but not control, any defense or settlement controlled by the Indemnified Party pursuant to this Section 8.4(c) (other than a dispute as to the Indemnifying Party’s liability to the Indemnified Party) and the Indemnifying Party shall bear its own costs and expenses with respect to such participation.

(d) If any Indemnified Party should have a claim against any Indemnifying Party hereunder which does not involve a Third Party Claim, the Indemnified Party shall notify the Indemnifying Party of such claim by the Indemnified Party, specifying the nature of and specific basis for such claim and the amount of the estimated amount of such claim (the “Indemnity Notice”). If the Indemnifying Party does not notify the Indemnified Party within thirty days from delivery of the Indemnity Notice that the Indemnifying Party disputes such claim, the amount or estimated amount of such claim as specified by the Indemnified Party shall be conclusively deemed a liability of the Indemnifying Party. If the Indemnifying Party has timely disputed such claim, as provided above, such dispute shall be resolved by litigation in an appropriate court of competent jurisdiction or as the parties otherwise at such time agree.

8.5. Payment of Indemnity Claim; Set Off.

Any indemnity claims shall be paid in cash by the Buyer to or on behalf of any Seller Indemnitee. If any Buyer Indemnitee is entitled to indemnification as a result of a this Article 8, Buyer shall have the right to offset the amount of the Adverse Consequences or Third Party Claim against any future payment of the Purchaser Price yet to be paid to Sellers (but not those payments previously paid unless such Adverse Consequences arose out of any breach by the Company or Sellers of a Fundamental Representation) pursuant to Article 1, subject to the provisions of this Section 8.5. If, at any time that a payment is due to Sellers as a result of the achievement of any of the events set forth in Section 1(a), and any Buyer Indemnitee is entitled to indemnification as a result of a claim for which such Indemnitee would, if such claim is successful, be entitled to offset, but such claim has not yet been resolved, then, (i) Buyer shall pay the amount equal to the amount of such payment less the maximum amount of such unresolved claim for indemnification to Sellers. Upon final resolution of such claim for indemnification, to the extent applicable, Buyer shall promptly make the payments to Seller that are due, less the amount of indemnification due, pursuant to such final resolution.

8.6. Knowledge of Breach.

For purposes of this Article 8, Sellers shall not be deemed to have breached any representation or warranty if a prudent individual would be expected to discover or otherwise become aware of the breach of, or of any facts or circumstances constituting or resulting in a breach of, such representation or warranty in the course of conducting a reasonably comprehensive investigation of the documents and information posted at least ten (10) business days prior to the date of this Agreement, and remaining so posted as of the date of this Agreement, to the virtual data room hosted by the Company via Google Drive and utilized in providing due diligence information and materials to Buyer and its representatives in connection with the transactions contemplated hereby.

8.7. Adverse Consequences.

As used in this Agreement, the term “Adverse Consequences” shall mean liabilities, losses, claims, damages, actions, suits, proceedings, demands, assessments, adjustments, obligations, costs, deficiencies, penalties, fines, expenses and other judgments (at equity or in law) and damages whenever arising or incurred, including amounts paid in settlement and reasonable attorney’s fees, costs and expenses of investigations.

8.8. Exclusivity.

The right of each party hereto to assert indemnification claims and receive indemnification payments pursuant to this Section 8 shall be the sole and exclusive right and remedy exercisable by such party with respect to any breach by the other parties hereto of any representation or warranty. Nothing in this Section 8.8 shall limit or restrict the ability or right of any Party hereto to seek injunctive or other equitable relief for any breach or alleged breach of this agreement or any provision hereof.

8.9. No Implied Representations.

Purchaser and Sellers acknowledge that, except as expressly provided herein, neither party hereto, and none of the affiliates of any party hereto, has made or is making any representations or warranties whatsoever, implied or otherwise.
