3.6 Payment Terms.

(a) Manner of Payment. All payments to be made by Retrophin under this Article 3 will be made in U.S. dollars by wire transfer to such bank account as Asklepion may designate.

(b) Records and Audits. Retrophin shall keep, and shall cause each of its Affiliates and licensees, to keep adequate books and records of accounting for the purpose of calculating all Contingent Payments and Royalties payable to Asklepion under Sections 3.4 and 3.5. For the seven (7) years next following the end of the calendar year to which each shall pertain, such books and records of accounting (including those of Retrophin’s Affiliates and licensees) shall be kept at each of their principal place of business and shall be open for inspection at reasonable times and upon reasonable notice by an independent certified accountant selected by Asklepion, and which is reasonably acceptable to Retrophin, for the sole purpose of inspecting the Contingent Payments and Royalties due to Asklepion under this Agreement. In no event shall such inspections be conducted hereunder more frequently than once every twelve (12) months. Such accountant must have executed and delivered to Retrophin and its Affiliates or licensees, a confidentiality agreement as reasonably requested by Retrophin, which shall include provisions limiting such accountant’s disclosure to Asklepion to only the results and basis for such results of such inspection. The results of such inspection, if any, shall be binding on both Parties. Any underpayments shall be paid by Retrophin within thirty (30) days of notification of the results of such inspection. Any overpayments shall be fully creditable against amounts payable in subsequent payment periods. Asklepion shall pay for such

***Confidential Treatment Requested

inspections, except that in the event there is any upward adjustment in aggregate Contingent Payments and/or Royalties payable for any calendar year shown by such inspection of more than […***…] of the amount paid, Retrophin shall reimburse Asklepion for any reasonable out-of-pocket costs of such accountant.

(c) Reports and Royalty and Contingent Payments. For as long as Contingent Payments or Royalties are due under Sections 3.4 or 3.5, Retrophin shall furnish to Asklepion a written report (each, a “Report”) for each calendar quarter, showing the amount of Net Sales of Products and Net Revenues in respect of Products and, as applicable, any Contingent Payment or Royalty due for such calendar quarter under Sections 3.4 or 3.5. Reports shall be provided within thirty (30) days of the end of the quarter for Net Sales and Net Revenues generated by Retrophin and its Affiliates, and within forty-five (45) days of the end of the quarter for Net Sales and Net Revenues generated by licensees. Royalty for each calendar quarter shall be due at the same time as such written Report for the calendar quarter. The Report shall include, at a minimum, the following information for the calendar quarter, each listed by Product and region: (i) the number of units of Products sold by Retrophin and its Affiliates and licensees on which Contingent Payments or Royalties are owed to Asklepion hereunder; (ii) the gross amount received for such sales; (iii) deductions taken from Net Sales as specified in the definition thereof; (iv) Net Sales and (v) Net Revenues. All Reports shall be treated as Confidential Information of Retrophin.

(d) Disputed Reports. Each Report shall be final, binding and conclusive, unless Seller or its designee notifies Buyer in writing of any disagreement therewith (an “Objection Notice”) within thirty (30) after its receipt thereof, specifying (a) those items as to which there is disagreement and (b) a reasonably detailed description of the basis, nature, dollar amount and extent of the dispute or disagreement. If Seller delivers an Objection Notice within such period, then for a period of twenty (20) business days from the date of delivery of the Objection Notice, Buyer shall afford Seller and its agents or other representatives with reasonable access during normal business hours to the books and records of Buyer and its licensees so as to enable its review of the Report and the information contained therein. Buyer and Seller shall attempt in good faith to resolve such dispute, and any resolution by them as to any disputed amounts shall be final, binding and conclusive. If Buyer and Seller are unable to resolve all disputes reflected in the Objection Notice within twenty (20) business days after the date of delivery of the Objection Notice (or such longer period as Buyer and Seller may mutually agree upon), then Buyer and Seller shall request Ernst & Young (the “Independent Accounting Firm”) to resolve any remaining disagreements. Buyer and Seller shall use their commercially reasonable efforts to cause the Independent Accounting Firm to make its determination within thirty (30) days of accepting its selection. The determination by the Independent Accounting Firm shall be final, binding and conclusive on Buyer and Seller and shall not be appealable. Buyer and Seller shall deliver to the Independent Accounting Firm all work papers and back-up materials relating to the unresolved disputes requested by the Independent Accounting Firm to the extent available to Buyer, Seller and their respective agents or other representatives. Buyer and Seller shall be afforded the opportunity to present to the Independent Accounting Firm any material related to the unresolved disputes and to discuss the issues with the Independent Accounting Firm; provided, however, that no such presentation or discussion shall occur without the presence of agents or other representatives of the Buyer and Seller. The determination of the Independent Accounting Firm shall be limited to the disagreements submitted to the Independent

***Confidential Treatment Requested

Accounting Firm. Upon resolution by the Independent Accounting Firm to its satisfaction of all such disputed matters, the Independent Accounting Firm shall cause to be prepared and shall deliver to Buyer and Seller a final Report setting forth the Net Sales and Net Revenues for the Products in respect of the calendar quarter at issue in the disputed Reported, and the date of such delivery by the Independent Accounting Firm shall be deemed the date on which the Report and the Net Sales and Net Revenues for the Products in respect of the calendar quarter at issue in the disputed Reported shall become final, binding and conclusive. The fees and expenses of the Independent Accounting Firm shall be borne equally by Seller and Buyer.

(e) Marketing and Sale of Cholic Acid Product. From and after the Closing Date, Buyer shall, and shall cause its Affiliates and its and its Affiliates’ successors and assigns to:

(i) keep complete, true and accurate books and records of all Net Sales and Net Revenues and deliver to Seller or its Affiliates, successors or assigns, the U.S. Commercialization Plan on an annual basis;

(ii) use Commercially Reasonable Efforts to commercialize, including development to support commercialization as commercially reasonable, the Cholic Acid Product in the United States in a manner consistent with the U.S. Commercialization Plan and in the rest of the world;

(iii) if, at any time, Buyer, its Affiliates, or any of their respective successors or assigns shall (A) consolidate with or merge with or merge into any other Person, or (B) sell, assign, convey, transfer, license, sublicense, lease or sublease all or any portion of the Assets, give a written notice to Asklepion or its designee (or their respective successors or assigns) setting forth the name and address of any such Person with which Buyer, its Affiliates or their respective successors or assigns engaged in such transaction described in clauses (A) and/or (B), together with the name, telephone number, facsimile number and email address of an individual contact at such Person and will provide a copy of such notice to such Person; provided, however, that if any such Person with which Buyer, its Affiliates or any of their respective successors or permitted assigns engages in a transaction contemplated by clauses (A) and/or (B) owns, holds or commercializes a […***…], then the assignment of this Agreement in connection with or pursuant to such transaction shall be permitted if, following the approval of Seller or its successors or permitted assigns (which approval shall not be unreasonably withheld), such Person shall affirmatively undertake to continue to use Commercially Reasonable Efforts with respect to the Cholic Acid Product […***…] owned, held or commercialized by such Person in an amount reasonably sufficient to compensate Seller or its successors or permitted assigns for […***…].

(iv) promptly furnish to Seller written notice of (A) the termination of any material contract with respect to the Cholic Acid Product, including, but not limited to, any Material Supplier Contract or Initial Distributor Agreement, that could have a material adverse effect on the business, financial condition or results of operation of the Buyer, taken as a whole,

***Confidential Treatment Requested

or (B) any material breach by any party to any Material Supplier Agreement or Initial Distributor Agreement;

(v) comply with all Applicable Laws with respect to the marketing, promotion and commercialization of the Cholic Acid Product, except where the failure to comply would not have a material adverse effect on the business, financial condition or results of operation of the Buyer, taken as a whole;

(vi) Retrophin shall perform its obligations under this Agreement and shall conduct its business in compliance with Applicable Law where the failure to comply would not have a material adverse effect on the business, financial condition or results of operation of the Buyer, taken as a whole. Without limiting the generality of the foregoing: (a) Retrophin shall ensure that all of its employees and consultants comply with Applicable Law, and shall implement and maintain policies and procedures to ensure such compliance, including maintaining a corporate compliance program that will include compliance monitoring focused on specific risk areas, including off-label promotion, fraud and abuse, and false claims, for the purpose of assessing whether Retrophin’s policies and procedures are being followed; and (b) Retrophin shall, and shall ensure that all of its employees and consultants, comply the Anti-Corruption Laws;

(vii) for the Competition Period not, directly or indirectly, (A) manufacture, produce, market, commercialize or supply any Competitive Product, without the prior written consent of Seller, or (B) acquire, own an interest in, manage, operate, join, control, lend money or render financial or other assistance to or participate in or be connected with, as an officer, employee, partner, stockholder, consultant or otherwise, any Person that competes in manufacturing, producing, marketing or supplying any Competitive Product; provided, that the provisions of this Section 3.6(e)(vii) shall not apply to […***…].

The Parties agree that the covenant set forth in Section 3.6(e)(vii) is reasonable with respect to duration and scope and necessary to protect the legitimate interests of Seller and its Affiliates, and that any violation thereof would cause irreparable injuries. Therefore, Buyer, on behalf of itself and its Affiliates and their respective successors and assigns, acknowledges and agrees that, in the event of a violation by Buyer or its Affiliates of any of the restrictions contained in Section 3.6(e)(vii), Seller or its Affiliates or their respective successor or assigns shall be entitled to obtain from any court of competent jurisdiction temporary, preliminary and permanent injunctive relief, in addition to any other rights Seller or its Affiliates or their respective successor or assigns may be entitled. In addition, if the final judgment of any such court declares that any term or provision of Section 3.6(e)(vii) is invalid or unenforceable, the Parties agree that the court making the determination of invalidity or unenforceability shall have the power to reduce the scope, duration, or area of the term or provision, to delete specific words or phrases, or to replace any invalid or unenforceable term or provision with a term or provision that is valid and enforceable and that comes closest to expressing the intention of the invalid or unenforceable term or provision, and Section 3.6(e)(vii) shall be enforceable as so modified.

(f) Taxes. Retrophin may withhold from payments due to Asklepion amounts for payment of any withholding tax that is required by law to be paid to any taxing authority with

***Confidential Treatment Requested

respect to such payments. Retrophin will give proper evidence from time to time as to the payment of any such tax.

(g) Late Charge. If Retrophin fails to make any payment under this Agreement or any Ancillary Agreement timely when due, Retrophin shall pay to Asklepion, in addition to any other sum due Asklepion under this Agreement or any Ancillary Agreement, a late charge equal to […***…] of such past due payment, compounding monthly (the “Late Charge”), which Late Charge is a reasonable estimate of the losses that may be sustained by Asklepion due to the failure of Retrophin to make timely payments. The Late Charge shall be due whether or not Asklepion declares a breach of this Agreement or otherwise demands immediate payment of the sums due under this Article 3. The right to impose the Late Charge shall not constitute a grace period or provide any right of Retrophin to make a payment other than on its due date. It is hereby expressly agreed that such Late Charge is to compensate Asklepion for costs incurred in connection with the administration of such late payment, and does not constitute a penalty. The Late Charge is in addition to, and not in any way in limitation of, any other money due by Retrophin under this Agreement or any Ancillary Agreement by reason of such late payment or otherwise.

3.7 Cholic Acid Product Inventory Payment.

(a) No more than five (5) days after the Closing Date, Retrophin will pay to Asklepion an amount in cash by wire transfer of immediately available funds equal to the cost (the “Pre-Closing Inventory Cost”) of the Cholic Acid Product Inventory, determined based upon a physical inventory of the Cholic Acid Product Inventory completed no earlier than three Business Days prior to the Closing Date.

(b) Within three Business Days after the Closing Date (the “Physical Inventory Date”), Retrophin shall be permitted to conduct a physical inventory of the Cholic Acid Product Inventory or to request from Asklepion its work paper or other supporting documentation with respect to the cost (the “Closing Inventory Cost”) of the Cholic Acid Product Inventory as of the Closing Date, and shall deliver to Asklepion a notice (the “Inventory Notice”) setting forth the Closing Inventory Cost, including the supporting detail thereof based on the physical inventory or work papers and supporting documentation, within five days after the Physical Inventory Date; provided that, if Retrophin shall not deliver an Inventory Notice to Asklepion on or prior to the Physical Inventory Date, then Buyer shall be deemed to have accepted Pre-Closing Inventory Cost and the Cholic Acid Product Inventory and cost thereof shall be determined to be final and binding on Retrophin and Asklepion.

(c) Asklepion shall have five days to review any Inventory Notice and to notify Retrophin in writing of any objections thereto. Within three days after Retrophin’s receipt of objections (if any) to the Inventory Notice from Asklepion, Retrophin shall notify Asklepion in writing if it accepts or rejects all or any portion of such objections; provided that, if Retrophin shall not deliver any response to the Seller in writing on or prior to the expiration of such 5-day period, then Retrophin shall be deemed to have accepted Asklepion’s objections to the Inventory Notice and Asklepion’s determination of the Closing Inventory Cost, which shall be determined to be final and binding on Retrophin and Asklepion. If Buyer does not accept all of Asklepion’s objections to the Inventory Notice, then Retrophin and Asklepion shall attempt to resolve any objections in good faith for a period of ten days. If the Parties shall be unable to resolve any

***Confidential Treatment Requested

objections to the Inventory Notice or the determination of the Closing Inventory Cost, then either Retrophin or Asklepion shall be permitted, at its sole cost or expense, to submit any remaining objections to the Independent Accounting Firm for resolution within ten days after engagement. The Independent Accounting Firm shall issue a written statement as to its resolutions of any outstanding objections to the Inventory Notice or the determination of the Closing Inventory Cost, which determination and the Inventory Notice shall be determined to be final and binding on Retrophin and Asklepion. The Independent Accounting Firm shall consider only those items and amounts that were set forth in the written notices of Retrophin and Asklepion and that remain unresolved. In resolving any Item of dispute, the Independent Accounting Firm may not assign a value to any item greater than the greatest value for such item claimed by either Party or less than the smallest value for such item claimed by either Party.

(d) If, following the final determination of the Closing Inventory Cost pursuant to this Section 3.7, the Closing Inventory Cost exceeds the Pre-Closing Inventory Cost, then Asklepion shall pay Retrophin by check or wire transfer of immediately available funds to an account designated by Retrophin in writing an amount equal to such excess within three (3) Business Days after date on which the Closing Inventory Cost is determined to be final. If, however, the Pre-Closing Inventory Cost exceeds the Closing Inventory Cost, then Retrophin shall pay Asklepion an amount equal to such excess within three (3) Business Days after date on which the Closing Inventory Cost is determined to be final.

During the Competition Period, the Seller and its Affiliates shall not, without the prior written consent of Buyer, directly or indirectly, not, (A) manufacture, produce, market, commercialize or supply any Competitive Product, or (B) acquire, own an interest in, manage, operate, join, control, lend money or render financial or other assistance to or participate in or be connected with, as an officer, employee, partner, stockholder, consultant or

otherwise, any Person that competes in manufacturing, producing, marketing or supplying any Competitive Product. The Parties hereto agree that the covenant set forth in this Section 6.3 is reasonable with respect to its duration and scope and necessary to protect the legitimate interests of Buyer, and that any violation thereof would cause irreparable injuries. Therefore, Seller, on behalf of itself and its Affiliates, acknowledges and agrees that, in the event of a violation by Seller or its Affiliates of any of the restrictions contained in this Section 6.3, Buyer shall be entitled to obtain from any court of competent jurisdiction temporary, preliminary and permanent injunctive relief, in addition to any other rights Buyer may be entitled.

In the event that such supplemented or amended Seller’s Disclosure Schedule reflects any event, condition or circumstance occurring or arising that is not otherwise prohibited pursuant to Sections 7.1 or 7.2 and which does not have a Material Adverse Effect on the Assets, then prior to the Closing, the specified representations and warranties made by Seller will be deemed automatically modified to reflect such event as of the date that such event occurs or arises. The delivery of any such supplemented or amended Seller’s Disclosure Schedule pursuant to this Section 6.4 will be deemed to have cured any misrepresentation or breach of warranty that otherwise might have existed hereunder by reason of such event, condition or circumstance and Buyer will not be entitled to terminate this Agreement nor will any Indemnitee of Buyer have any claim to indemnification or reimbursement for any such event.

6.5 Cooperation with Financials.

Between the Effective Date and the Closing Date, Seller will keep Buyer reasonably informed of the status and occurrence of material negotiations with respect to any Material Supplier Contract or any amendment thereto, as well as material drafts or material changes in the drafts of any Material Supplier Contract or any amendment thereto.
