(ii) For all Product sold in Territory Zone 2, Buyer shall make payments to Sellers’ Representative on aggregate Net Sales of the Product equal [***] of the first [***] in aggregate annual Net Sales generated by the Product plus [***] of aggregate annual Net Sales of the Product between [***] and [***] plus [***] of aggregate annual Net Sales of the Product in excess of [***].

(i) In the event that the Development Costs incurred after the Closing and prior to the expiration of the Earn-Out Period exceed [***], then Buyer may offset such excess amount of Development Costs against any and all Earn-Out Payments that would otherwise become payable thereafter.

(ii) If Buyer reasonably determines that it cannot develop or commercialize the Product without infringing, misappropriating or otherwise violating the Intellectual Property of any Third Party, then on a calendar quarter-by-calendar quarter basis, Buyer may offset up to [***] of any amounts due to any Third Party in consideration for a grant of rights to such Intellectual Property in such calendar quarter against any and all Earn-Out Payments otherwise due to Sellers in such calendar quarter; provided that the Earn-Out Payment due in any calendar quarter may not be reduced pursuant to this Section 2.3(c)(ii) by more than [***] of the amount otherwise due to Sellers in such calendar quarter, but Buyer may carry forward any such amounts that Buyer would otherwise be permitted to offset against Earn-Out Payments but for the foregoing [***] floor and apply such deductions against Earn-Out Payments due to Sellers in subsequent calendar quarters until fully offset.

(iii) In the event Buyer grants a sublicense of its rights to the Product, cash payments associated with the grant of such a sublicense, including any closing payments and milestone payments, will be added to Net Sales in the calendar quarter in which such payments are received by Buyer; provided, however, that if Buyer enters into a sub-licensing agreement with [***], or with [***], Buyer will directly pay to Sellers Representative [***] of such cash payments when they are received and such amounts will not be counted as Net Sales.

(d) Determination of Earn-Out Revenues. The Buyer and Company shall, within 60 days after the conclusion of each calendar quarter (ending December 31, March 31, June 30, and September 30) during the Earn-Out Period, send to Sellers’ Representative a report

setting forth the determination of the Net Sales accrued through the end of the preceding quarter and cumulatively during the entire Earn-Out Period. Within 60 days after the end of each calendar quarter during the Earn-Out Period, Buyer will submit a written report to Sellers’ Representative setting forth for such quarter the quantity of Products sold by Buyer or any of its Affiliates to unaffiliated third Persons, the aggregate Net Sales thereof and the Earn-Out payable with respect thereto. Buyer will keep books of account and other records in sufficient detail so that the amount of the Earn-Out to be paid to Sellers’ Representative hereunder can be properly ascertained. At the request of Sellers’ Representative, Buyer will permit, and will cause its Affiliates to permit, a certified public accountant or attorney or other representative selected by Sellers to have access to such books and records as may be necessary to determine the correctness of any report or Earn-Out under this Section 2.3(b). Any such examination will be made during reasonable business hours at the place of business of Buyer in the United States and will be at Sellers’ sole expense, subject to Section 2.3(f) below.

(e) Challenges to Quarterly Reports. If Sellers’ Representative does not send to Buyer a notice challenging a quarterly report within 45 days from the receipt of such quarterly report, Sellers shall be deemed to have accepted such determination and such determination shall be deemed binding and final (other than with respect to any underpayment by Buyer identified by the certified public accountant, attorney or other representative of Sellers in the course of the examination of the applicable books and records of Buyer pursuant to Section 2.3(d) above). If a notice is delivered to Buyer by Sellers’ Representative pursuant to which it challenges a quarterly report (such challenge including the request for additional information or the right to access books and records of Buyer) within 45 days after the date Sellers’ Representative receives the quarterly report, the dispute resolution procedures set forth in Section 2.3(e) shall govern. Seller agrees to keep confidential and not disclose, divulge, or use for any purpose (other than for purposes of the Earn-Out Payments as contemplated herein) any confidential information obtained from Buyer pursuant to the terms of this Section 2.3.

(f) Dispute Resolution. If Sellers’ Representative timely delivers a challenge to a quarterly report, then during the 30 days following delivery of the challenge notice, Buyer and Sellers’ Representative shall use reasonable good faith efforts to reach agreement on the disputed items or amounts in order to determine the Earn-Out Payment or other amount. If, during such period, the Parties are unable to reach agreement, they shall promptly thereafter cause a firm of independent public accountants with regional or national standing, such firm having no material relationship to Buyer or Sellers and reasonably acceptable to Buyer and Sellers’ Representative (the “Accounting Referee”), promptly to review this Agreement and the disputed items or amounts for the purpose of calculating the Earn-Out Payment or other amount in question. In making such calculation, the Accounting Referee shall consider only those items or amounts to which Sellers have disagreed, shall be bound by the terms and provisions of this Agreement, and shall not ascribe a value to any disputed item or amount higher or lower, as the case may be, than the highest or lowest value ascribed by Buyer or Sellers’ Representative in their submissions to the Accounting Referee. For purposes of assisting the Accounting Referee in making such calculation, each of Sellers’ Representative and Buyer shall submit a proposed determination of the applicable items or amounts in dispute. The Accounting Referee shall deliver to Buyer and Sellers’ Representative, as promptly as practicable, a report setting forth such calculation. Such report shall be final and binding upon the Parties. The cost of such review

and report shall be borne by the Parties in proportion to the final adjustment determination made by the Accounting Referee relative the amount challenged by the Sellers.

(g) Timing and Manner of Contingent Payments. Buyer shall pay to Sellers’ Representative the Earn-Out Payments generated from the quarterly Net Sales reflected in the quarterly report within 60 days after the end of the applicable calendar quarter. Payment shall be paid by wire transfer of immediately available funds to Sellers’ Representative pursuant to written wire transfer instructions delivered to Buyer by Sellers’ Representative from time to time.

(h) Assignment of Earn-Out Payments. The right of each Seller to the Earn-Out Payments may not be sold, transferred or otherwise assigned by such Seller without the consent of Buyer, which consent shall not be unreasonably withheld, conditioned or delayed. Notwithstanding the foregoing, NPC may assign its right to the Earn-Out Payments to its secured lender(s) from time to time with or without the consent of Buyer; provided that any such secured lender has complied with Section 2.4(b) below.

(i) For all purposes, including Tax purposes, the Earn-Out Payments shall be treated as additional purchase price paid by the Buyer to the Sellers for the Shares (except (i) the right of any Seller to the Earn-Out Payments has been assigned pursuant to Section 2.3(h) or (ii) to the extent a portion of each Earn-Out Payment is treated as imputed interest for Tax purposes), and the parties will file all Tax Returns consistent with such treatment.

Section 2.4. Withholding. Buyer shall be entitled to deduct and withhold from any amounts otherwise payable pursuant to this Agreement to Sellers such amounts as are required to be withheld with respect to the making of such payment under the Code, and the rules and regulations promulgated thereunder, or any other provision of applicable Tax Laws; provided that (a) the Buyer shall give at least five (5) Business Days prior written notice to, and shall consult with, the applicable Seller if it believes that any amount is required to be deducted and withheld under current applicable Tax Law with respect to the Purchase Price and (b) as a condition to providing consent to any assignment of the right of any Seller to the Earn-Out Payments pursuant to Section 2.3(h) (including any assignment by NPC to its secured lender(s)), Buyer may require Seller to provide Tax certifications from the proposed assignee that eliminates any potential deductions and withholdings that the Buyer or other applicable withholding agent may believe it is required to make under applicable Tax Law. To the extent that amounts are so withheld and paid over to the appropriate Governmental Entity, such withheld amounts shall be treated for all purposes of this Agreement as having been paid to the Person in respect of which such deduction and withholding was made.

ARTICLE IV
COVENANTS

Section 4.1. Publicity. No Seller shall issue a press release or make any other public announcement concerning the transactions contemplated by this Agreement or with respect to the Product or the development or commercialization thereof, in each case, without the prior written consent of the Buyer, except as such release or announcement, upon the advice of outside counsel, may be required by Law, in which case the Seller required to make the release or announcement shall allow the Company and the Buyer reasonable time to comment on such release or announcement in advance of such issuance. Nothing herein will restrict Buyer from issuing a press release or making any public announcement concerning the transactions contemplated by this Agreement or relating to the Product.

Section 4.2. Further Assurances. On and after the Closing Date, the Sellers, the Company, and the Buyer shall each cooperate and use all of their respective commercially reasonable efforts to take or cause to be taken all appropriate actions and do, or cause to be done, all things necessary or appropriate to consummate and make effective the transactions contemplated hereby, including the execution of any additional documents or instruments of any kind, the transfer of assets or property, the obtaining of consents which may be reasonably necessary or appropriate to carry out any of the provisions hereof and the taking of all such other actions as such Party may reasonably be requested to take by the other Party hereto from time to time, consistent with the terms of this Agreement and the other agreements, instruments and documents contemplated hereby, in order to effectuate the provisions and purposes hereof and thereof and the transactions contemplated hereby and thereby. For the avoidance of doubt, this Section 4.2 shall be deemed to require the Company and Sellers to use commercially reasonable efforts to assist by in providing any notice to the FDA or any other Governmental Entity that Buyer determines to be necessary or advisable following the Closing Date to effect the transactions contemplated by this Agreement.

Section 4.3. Confidentiality.

(a) All information received by or behalf a Party prior to the Closing that is proprietary to another Party shall be held as “Confidential Information,” as defined in, and pursuant to the terms of, the Confidentiality Agreement, subject to the limitations and exceptions set forth therein. Following the Closing Date, the terms of this Agreement will control and govern all Confidential Information of the Parties.

(b) Each Party shall each keep confidential, and shall use reasonable efforts to cause its respective Affiliates, officers, directors, employees, advisors and auditors to keep confidential, all Confidential Information of any other Party or any of its Affiliates; provided, that a Party may disclose Confidential Information of another Party to the extent required by applicable Law. After the Closing, all Confidential Information relating to the Company, the Business and the Product shall be deemed to be the Confidential Information of Buyer.

(c) Nothing herein shall be deemed to restrict or prevent NPC from disclosing the terms of this document and the transaction in general to NPC’s secured creditor, now or hereafter existing.

Section 4.4. Non-Competition and Non-Solicitation. Except in accordance with the terms and conditions of this Agreement and the other Transaction Documents and subject to applicable Law, for the duration of the Earn-Out Period, the Sellers shall not, and the Sellers shall cause their respective Affiliates not to, engage, on their own behalf or on behalf of any other Person, in any Competitive Activity. It is the understanding of the Parties that the scope of the covenants contained in this Section 4.4 both as to time and area covered, are reasonable and necessary to protect the rights of the Parties. It is the Parties’ intention that these covenants be enforced to the greatest extent (but to no greater extent) in time, area, and degree of participation as is permitted by applicable Law. In the event that any provision of this Section 4.4 is determined by any court of competent jurisdiction to be unenforceable by reason of its being extended over too great a time, too large a geographic area or too great a range of activities, such

provision will be deemed to be modified to permit its enforcement to the maximum extent permitted by applicable Law.

Section 4.5. Tax Matters.

(a) Transfer Taxes. All transfer, documentary, sales, use stamp, registration and other such Taxes, and any conveyance fees or recording charges (collectively, “Transfer Taxes”) incurred in connection with the transactions contemplated by this Agreement shall be paid one-half by the Sellers and one-half by the Buyer when due and payable.

(b) Filing of Returns. The Sellers shall, at their sole cost and expense, prepare all Tax Returns of the Company for any Tax period ending on or before the Closing Date. The Sellers shall submit drafts of such Tax Returns to Buyer for its review at least 30 days prior to the due date for the filing thereof (taking into account any permitted extensions). The Buyer shall have the right to review and comment on such Tax Returns and the Sellers shall make such changes thereto as are reasonably requested by the Buyer. Upon completion of Sellers and approval by Buyer of such Tax Returns, Buyer shall cause the Company to timely file such Tax Returns. The Sellers shall cause to be timely paid and shall be responsible for all Taxes due with respect to all such Tax Returns (taking into account any applicable extensions of time to file). Buyer shall prepare and file all Tax Returns of the Company for any Tax period ending after the Closing Date; provided, however, that not later than 30 days prior to the due date for filing of a Straddle Taxable Period Tax Return Buyer shall provide Sellers with a copy of drafts of such Tax Return and shall consider in good faith any comments from the Sellers on the portions of such Tax Return that relate to the Pre-Closing Taxable Period. In the case of a Straddle Taxable Period Tax Return, Sellers shall pay to Buyer the Sellers’ share of any Taxes due with respect to such Tax Return not later than seven days prior to the due date for filing such Tax Return.

(c) Amendments to Tax Returns. Except as required by Law, without the prior written consent of Sellers, which consent shall not be unreasonably withheld, conditioned or delayed, Buyer shall not make, change or rescind any Tax election, amend any Tax Return or take any position on any Tax Return, take any action, omit to take any action or enter into any other transaction that would have the effect of increasing the Tax liability or reducing any Tax asset of any of the Companies in respect of any Pre-Closing Taxable Period.

(d) Tax Claims. Sellers shall have the right to control, at their sole cost and expense, and Buyer shall have the right to participate in, at its sole cost and expense, any Tax Claim that relates to any Pre-Closing Taxable Period to the extent Sellers conduct the defense of such Tax Claims actively, diligently and in good faith. If Sellers elect not to control any such Tax Claims, then Buyer shall control such matter, provided, that (i) Sellers’ Representative shall have the right to participate in any such matter, (ii) Buyer shall keep Sellers’ Representative reasonably informed of the status of such matter (including providing Sellers’ Representative with copies of all written correspondence regarding such matter), and (iii) Sellers shall promptly reimburse the Buyer for any and all reasonable expenses incurred in connection with Buyer’s defense of such Tax Claims.. In the case of any Tax Claim for Taxes that applies to a Straddle Taxable Period and to the extent such Tax Claim would result in an indemnification obligation by the Sellers under this Agreement (A) each Party may participate in the Tax Claim; (B) such Tax Claim shall be controlled by that Party that would bear the burden of the greater portion of

the sum of the adjustment and any corresponding adjustments that may reasonably be anticipated for any Tax periods; and (C) each Party shall bear the appropriate portion of the expenses of such Tax Claim. Except as otherwise provided in Section 4.5(d), in the case of any audit, proceeding, adjustment or other claim made by any Governmental Entity for Taxes that applies to any Post-Closing Taxable Period and/or to the extent the Sellers have no indemnification obligation under this Agreement, Buyer shall have the right to control the conduct of such audit or proceeding in its sole discretion.

(e) Cooperation. Buyer, the Company, and Sellers will cooperate fully, as and to the extent reasonably requested by the other Party, in connection with any Tax matters relating to the Company (including by the provision of reasonably relevant records or information). The Party requesting such cooperation will pay the reasonable out-of-pocket expenses of the other Party.

(f) Straddle Taxable Period. For purposes of this Agreement, in the case of any Straddle Taxable Period, the amount of any Taxes of the Company not based upon or measured by income, activities, events, the level of any item, gain, receipts, proceeds, profits or other similar items for Tax periods (or the portion thereof) ending on or before the Closing Date will be deemed to be the amount of such Taxes for the entire Tax period multiplied by a fraction, the numerator of which is the number of days in the Tax period ending on the Closing Date and the denominator of which is the number of days in such Straddle Taxable Period. The amount of any other Taxes for a Straddle Taxable Period that relates to the Tax period (or the portion thereof) ending on or before the Closing Date will be determined based on an interim closing of the books as of the end of the day on the Closing Date, provided, however, that any item determined on an annual or periodic basis (such as a deduction for depreciation or real estate Taxes) shall be apportioned on a daily basis.

Section 4.6. No Additional Warranties or Representations; Due Diligence. Buyer, on behalf of itself and its affiliates, acknowledges and agrees that neither it nor any of its or their officers, directors, managers, employees, agents, attorneys, accountants, advisors or representatives (“Buyer Representatives”) has relied, and none of such Persons is relying upon any statement, warranty or representation (whether written or oral) not expressly set forth in this Agreement. Buyer, on behalf of itself and its affiliates, acknowledges that none of Sellers or any of their respective officers, directors, employees, partners members, managers, attorneys or agents, has made any representation or warranty, expressed or implied, as to the accuracy or completeness of any information regarding the Company or its business, properties or assets, which has been communicated, furnished or made available to Buyer or any Buyer Representatives, except as expressly set forth in this Agreement. None of the Sellers shall have, or be subject to, any liability to any Indemnified Party or other Person resulting from the distribution to Buyer or any Buyer Representatives, or any of Buyer’s or Buyer Representatives’ use of, any information, documents or materials made available to any of them in due diligence, including any information, documents or materials stored on computer disks or online or physical data rooms, provided during managements presentations, or in any other forms in expectation of the transactions contemplated by this Agreement, except as expressly set forth in this Agreement.

ARTICLE V
INDEMNIFICATION

Section 5.1. Survival. The representations and warranties contained in this Agreement and the certificates contemplated hereby shall survive the Closing for a period of 18 months and shall at that time expire, and no indemnification claim under this Article V (a “Claim”) for a breach of any representation or warranty may be brought after such 18-month period; provided, however, that if any Party provides written notice to the other Party of an indemnification claim under this Article V for a breach of a representation or warranty prior to the expiration of such 18-month period, then such claim shall survive until it is fully and finally resolved and any obligations with respect thereto are fully satisfied; and provided, further, that, notwithstanding anything herein to the contrary, (a) the Fundamental Representations and all corresponding claims for indemnification and claims for indemnification under Section 5.2(b) shall remain in full force and effect until the expiration of the applicable statute of limitations, and (b) all of the covenants and agreements contained in this Agreement that by their nature are required to be performed after the Closing shall survive the Closing until fully performed or fulfilled. Any Claim not submitted in writing (and which must contain in reasonable detail the legal and factual basis therefor) by the Person seeking indemnification pursuant to this Article V (the “Indemnified Party”) to the applicable Party from whom it is seeking indemnification (the “Indemnifying Party”) prior to the expiration of the applicable survival period shall be deemed to have been waived and shall be absolutely and forever barred and unenforceable.

Section 5.2. Indemnification of the Buyer Parties. From and after the Closing, the Sellers shall indemnify and hold harmless the Buyer, its Affiliates, and each of their respective officers, directors, shareholders, employees, agents, partners, managers, members, representatives, successors and permitted assigns (collectively, the “Buyer Parties”, but for the avoidance of doubt, in each case, excluding the Sellers) from and against, and shall pay to the Buyer Parties the amount of or reimburse them for, all losses, damages, Liabilities, fines, obligations, Taxes, costs and expenses (including reasonable attorney’s fees and expenses and all reasonable amounts paid in investigation or defense) (collectively, “Losses”) incurred by a Buyer Party that arises out of or results from:

(a) any breach of any of the representations or warranties of the Sellers set forth in this Agreement or in any of the other Transaction Documents, or contained in any certificate, instrument, or document delivered at the Closing by the Sellers or the Company pursuant to the Agreement or the other Transaction Documents;

(b) all Liabilities of the Company for any and all (i) Taxes with respect to any Pre- Closing Taxable Period and any Transfer Taxes for which the Sellers are liable pursuant to Section 4.5(a), (ii) Sellers’ Expenses or (iii) Indebtedness of the Company;

(c) all Liabilities arising as a result of, or relating to, activities conducted by or on behalf of the Company on or prior to the Closing, including any Liabilities arising out of or relating to (i) any discovery, research and development of the Product, (ii) execution, delivery or performance of this Agreement or (iii) any Legal Proceeding; or

(d) the failure of the Company (with respect to its pre-Closing obligations only) or of the Seller to perform any of its respective covenants or other agreements contained in this Agreement or in any of the other Transaction Documents.

The indemnification obligations of each Seller under this Article V shall be several and not joint, and, except in the case of intentional fraud or misrepresentation, no Seller shall have liability pursuant to this Article V in an aggregate amount in excess of such Seller’s pro rata portion of the Indemnity Cap (as hereinafter defined). Subject to the limitations set forth in this Section 5.2 and Section 5.4, in the event that a Buyer Party suffers, sustains or becomes subject to a Loss indemnifiable under this Section 5.2, and seeks to enforce its rights to indemnification hereunder, such Buyer Party shall proceed directly against each Seller for an amount equal to such Seller’s Pro Rata Share of such Buyer Loss; provided, that no Seller shall have any liability in an amount in excess of such Seller’s Pro Rata Share of such Buyer Loss.

Section 5.3. Indemnification of Sellers. From and after the Closing, the Buyer shall indemnify and hold harmless the Sellers from and against, and shall pay to the Sellers the amount of or reimburse them for, all Losses incurred by a Seller that arises out of or results from:

(a) any breach of any of the representations or warranties of the Buyer set forth in Section 3.2 of this Agreement or contained in any certificate, instrument or document delivered at the Closing by the Buyer, and

(b) the failure of the Buyer to perform any of its respective covenants or other agreements contained in this Agreement.

Section 5.4. Provisions Related to Indemnification of the Indemnified Parties.

(a) Neither Sellers nor Buyer shall be liable for any Losses under the indemnification obligations set forth in Section 5.2(a) or 5.3(a), as applicable, unless and until the aggregate amount of such Losses exceeds [***] (the “Basket”), and then such Person shall be entitled to be indemnified and held harmless for the full amount of such Losses, including the Losses equal to or less than the Basket, but only up to a maximum amount equal to [***] of the Closing Consideration (the “Indemnity Cap”); provided, however, that the Basket and the Indemnity Cap shall not apply to Losses resulting from (i) intentional fraud or misrepresentation, (ii) breaches of any Fundamental Representation or (iii) other claims for indemnification under Section 5.2(b)-(e); provided, further, that (i) the maximum aggregate liability of the Sellers for breaches of Fundamental Representations shall not exceed a maximum amount equal to the [***], and (ii) the maximum aggregate liability of the Sellers for claims for indemnification under Section 5.2(b)-(d) shall not exceed a maximum amount equal to the [***].

(b) For purposes of Section 5.2(a) and Section 5.3(a), in calculating the amount of any Loss with respect to any such breach or alleged breach, all qualifications in the applicable representation or warranty referencing the terms “material,” “materiality,” “Material Adverse Effect” or other terms of similar import or effect shall be disregarded.

(c) With respect to each Claim, the Indemnified Party shall use reasonable efforts to assert and prosecute and pursue diligently all claims under all applicable insurance policies or coverage, and any Losses that may be recovered by the Indemnified Party with

respect to such Claim shall be net of any insurance proceeds received or coverage obtained with respect thereto. To the extent that insurance proceeds are collected or coverage obtained after a Claim has been settled, the Indemnified Party shall restore the Indemnifying Party to the same economic position as would have existed had such insurance proceeds been collected or coverage been obtained prior to the settlement of such Claim. In addition, the Losses that may be recovered by an Indemnified Party shall be net of any Tax benefit realized in cash by, or that reduces cash Tax payments of, the Indemnified Party in the year of indemnification as a result of the Loss. In computing the amount of any such Tax benefit, the Indemnified Party shall be deemed to first utilize all available expenses, deductions, credits or other Tax attributes before utilizing any Tax attributes arising as a result of the Loss.

(d) Sellers shall not have any liability hereunder for Losses arising from or relating to any breach of representation or warranty if Buyer had Knowledge as of the Closing Date of the fact, circumstance, condition or event constituting such breach.

Section 5.5. Indemnification Procedures and Related Provisions.

(a) Upon the occurrence of any event that any Indemnified Party asserts to be the basis for a Claim against the Indemnifying Party, the Indemnified Party shall notify (such notice, a “Claim Notice”) the Indemnifying Party of the Claim after receiving notice or becoming aware of such Claim, describing the Claim in reasonable detail, with supporting documentation to provide the factual basis for such Claim (to the extent available) and the estimated amount reasonably necessary to satisfy such Claim; provided that the failure to so notify the Indemnifying Party shall not relieve the Indemnifying Party of its obligations hereunder except to the extent that (and only to the extent that) such failure shall have caused the damages for which the Indemnifying Party is obligated to be greater than such damages would have been had the Indemnified Party given the Indemnifying Party prompt notice hereunder. Whenever the Indemnified Party shall have given a Claim Notice to the Indemnifying Party, the Indemnifying Party may, within 30 days after receipt of such Claim Notice, notify the Indemnified Party that the Indemnifying Party disputes the Claim for indemnification set forth in the Claim Notice (a “Dispute Notice”), and if no Dispute Notice is given to the Indemnified Party within such 30 day period, the Claim shall be deemed final and binding for all purposes of this Article V.

(b) The Indemnified Party and the Indemnifying Party agree to make available to each other, their counsel and other representatives, all reasonably requested information and documents available to them which relate to a Claim in order to determine the existence and amount of Loss and resolve any disputes relating to same.

(c) The Indemnified Party and the Indemnifying Party shall cooperate in the defense of any third-party Action that the Indemnified Party asserts to be the basis for a Claim, with such cooperation to include (i) the retention and the provision to the Indemnified Party and Indemnifying Party of records and information that are reasonably relevant to such Action and (ii) reasonable access to employees on a mutually convenient basis for providing additional information and explanation of any material provided hereunder.

(d) The Indemnifying Party will make promptly, and in any event within ten days, any payment required to be made by it to the Indemnified Party under this Article V. Any claims for indemnification, whether or not disputed, shall be resolved pursuant to the provisions of this Agreement and those other Transaction Documents which are relevant to the claims.

(e) Notwithstanding anything contained in this Agreement to the contrary, neither Party shall be liable to the other Party or to any Indemnified Party under this Agreement for any Excluded Losses except (i) to the extent that an Indemnified Party pays such Losses or other items in connection with a third-party Action with respect to which the Indemnified Party is entitled to indemnification hereunder or (ii) in the case of intentional fraud or misrepresentation.

Section 5.6. Exclusive Remedy. Except in the case of intentional fraud or misrepresentation, and subject to Section 6.15, the remedies provided in this Article V shall be the sole and exclusive remedies of the Parties for all claims, Losses and disputes arising out of any matter set forth in or related to this Agreement or the subject matter hereof and will supersede and replace all other rights and remedies arising out of this Agreement that any of the Parties (or their Affiliates) may have at law or in equity.

Section 5.7. Tax Treatment of Indemnity Payments. For all Tax purposes, the Parties agree to treat indemnity payments made pursuant to this Agreement as an adjustment to the consideration for the Shares to the extent permitted by applicable Tax Law.

Section 5.8. Certain Additional Limitations.

(a) Notwithstanding anything to the contrary in this Agreement, in calculating amounts payable to an Indemnified Party hereunder, the amount of any indemnified Loss shall be determined without duplication of any recovery by reason of the state of facts giving rise to such Claim constituting a breach of more than one representation, warranty, covenant or agreement.

(b) Notwithstanding anything to the contrary in this Agreement, no Indemnifying Party shall be liable for any Losses to the extent that the Losses suffered by the applicable Indemnified Party result from any improper or tortious act by the Indemnified Party or its Affiliates.

Section 5.9. Right to Setoff. Upon notice to the Sellers, Buyer shall have a claim and right of setoff as to any amount to which any Indemnified Party is entitled under this Article V against amounts otherwise payable to Sellers under any provision of this Agreement, including its payment of any portion of the Earn-Out. The exercise of such right of setoff by Buyer in good faith, whether or not ultimately determined to be justified, will not constitute a breach of Buyer’s obligation to pay the Earn-Out or any other amounts due under this Agreement. Neither the exercise of nor the failure to exercise such right of setoff will constitute an election of remedies or limit Buyer in any manner in the enforcement of any other remedies that may be available to it, including Buyer’s right to recover the amount by which any amount due to Buyer exceeds the Earn-Out. To the extent that liability for or the amount of indemnifiable Losses in respect of an Action or Claim against a Seller has not yet been finally determined in accordance with this

Agreement, Buyer shall be entitled to withhold payment of any portion of the Earn-Out otherwise due and payable to such Seller (up to the amount of indemnifiable Losses that Buyer in good faith reasonably determines are likely to be incurred upon the advice of counsel) and place such amounts in escrow with an escrow agent mutually acceptable to the Parties until such liability or the amount of indemnifiable Losses has been finally determined.

Section 5.10. Duty to Mitigate. Each of the Parties agrees that no Indemnified Party can recover Losses to the extent that such Losses could have been reasonably mitigated or avoided after such Indemnified Party became aware of any event or condition that could reasonably be expected to give rise to those Losses that are indemnifiable hereunder. In such event, all costs incurred by the Indemnified Parties in connection with any such mitigation efforts actually taken will be includable as Losses.

ARTICLE VI
ADDITIONAL OPERATIVE PROVISIONS

Section 6.1. Assignment; Binding Effect. This Agreement and the rights hereunder are not assignable by Sellers unless such assignment is consented to in writing by the Buyer, which consent shall not be unreasonably conditioned, delayed or withheld. This Agreement and all the provisions hereof shall be binding upon and shall inure to the benefit of the Parties hereto and their respective successors, heirs, and permitted assigns. For purposes of clarity, the Buyer shall be permitted, without the consent of the Sellers, (a) to assign its rights hereunder to any of its Affiliates or (b) to make a collateral assignment of its rights hereunder to its or its Affiliates’ lenders (or an agent thereof) for security purposes and such lenders (or agent thereof) may exercise remedies in connection therewith, subject only to such restrictions as arise by operation of the governing Law; provided, however, that no such assignment under (a) or (b) shall release, terminate or affect Buyer’s obligations or liability hereunder. For the avoidance of doubt, a change of control transaction (whether by merger, consolidation, reorganization, acquisition, sale or otherwise) of any direct or indirect parent company of Buyer shall not be deemed an “assignment” for purposes of this Section 6.1 or Section 6.2. Notwithstanding anything in this Section 6.1 or Section 6.2, Buyer shall provide Sellers’ Representative reasonable prior written notice of any assignment of this Agreement or the rights hereunder.

Section 6.2. Reversion Right. If Buyer assigns this Agreement or the License Agreement to, or otherwise sells or transfers the Business to, a Third Party (the “Acquiring Party”), then within 60 days after the closing of such foregoing assignment transaction (the “Confirmation Period”), the Acquiring Party shall provide to Sellers’ Representative written confirmation of the Acquiring Party’s intent to satisfy the requirements of Section 6.3 and to pay any Earn-Out due to Sellers under Section 2.3 (a “Confirmation Notice”). If the Acquiring Party does not provide Sellers’ Representative a Confirmation Notice, Sellers, through the Sellers’ Representative, may elect, by giving written notice to the Acquiring Party within 90 days following the end of the Confirmation Period, to have Acquiring Party assign to Sellers’ Representative, in exchange for [***], all of the Acquiring Party’s right, title and interest in the Business, including any Regulatory Approvals for the Product in the Territory and any Company Intellectual Property, which assignment shall occur as soon as practicable, as reasonably determined by Sellers. The Parties agree that, following the foregoing assignment and reversion of rights to the Product to Sellers’ Representative, the Acquiring Party and Buyer shall have no

further obligations to Sellers pursuant to Sections 2.3 and 6.3 (except, in the case of Buyer, with respect to any Earn-Out Payments already accrued and payable to Sellers prior to the consummation of the sale, transfer or assignment of rights from Buyer to the Acquiring Party described above).

Section 6.3. Commercially Reasonable Efforts. After the Closing and until the end of the Earn-Out Period, subject to Section 6.2, Buyer shall use Commercially Reasonable Efforts to (i) receive approval by the FDA of the NDA for the Product, and (ii) otherwise develop and commercialize the Product. “Commercially Reasonable Efforts,” for purposes of this Section 6.3, means efforts and resources customarily used in the pharmaceutical business by a company of similar size with respect to the development and/or commercialization of a product of a market potential similar to the market potential of the Product with similar commercial and scientific potential at a similar stage in their lifecycle taking into consideration all relevant factors including their safety and efficacy, product profile (including the approved labeling and indication under the applicable NDA) the cost and timing to develop, the cost of and timing of clinical trials or comparative testing, the competitiveness of alternative formulations or products, as applicable, the anticipated or actual nature and extent of their market potential and exclusivity (including without limitation patent coverage and regulatory exclusivity), the likelihood, timing and cost of seeking and obtaining Regulatory Approval, and market potential and estimated profitability, including the amounts of marketing and promotional expenditures. Notwithstanding the foregoing, the Sellers acknowledge and agree that (a) the use of Commercially Reasonable Efforts by Buyer may result in ceasing development, manufacturing or commercialization activities with respect to the Product in any country in the Territory or in the Territory as a whole and (b) within the context of Commercially Reasonable Efforts, Buyer shall have discretion with respect to the timing and manner of all development, manufacturing and commercialization activities with respect to the Product and any and all expenditures by or on behalf of Buyer in connection therewith. Within 60 days following the Closing Date, Buyer shall provide to Seller’s Representative a written plan containing reasonable detail for the development of the Product through approval by the FDA of the NDA for the Product. Within 60 days following the end of each calendar quarter ending thereafter, Buyer shall provide Seller’s Representative a written update on progress toward completion of such development plan. In the event of any dispute arising under this Section 6.3, then the Parties shall first attempt in good faith to reach a mutually agreeable resolution with respect to the Buyer’s compliance with this Section 6.3; provided, that if the Parties are unable to reach a mutually agreeable resolution within 30 days after commencing such discussions, then either Buyer or Sellers’ Representative may, by written notice to the other Party, refer such matter to the Chief Executive Officers of Buyer and of the Sellers’ Representative for attempted resolution by good faith negotiation for a period of 30 days after such notice is received. If such Chief Executive Officers are unable to resolve such matter within such 30 day period, then each Party may, in its sole discretion, seek resolution in accordance with Article V and Section 6.5.

Section 6.4. Choice of Law. This Agreement and all claims arising from and relating to this Agreement and the transactions contemplated hereby shall be governed by and interpreted and enforced in accordance with the Laws of the State of Delaware, without regard to the conflicts of Laws rules thereof.

Section 6.5. Consent to Jurisdiction; Waiver of Jury Trial. The federal or state courts of the State of Delaware shall have exclusive jurisdiction to hear and decide any suit, action, proceeding or claim that may arise out of or in connection with this Agreement or the transactions contemplated hereby, and the Parties hereby consent to personal jurisdiction in those courts. Each of the Parties irrevocably waives its right to a jury trial in connection with any suit, action, proceeding or claim arising out of or relating to this Agreement or the transactions contemplated hereby.

All notices, requests, demands and other communications under this Agreement shall be in writing and shall be deemed to have been duly given (a) if delivered personally or actually received, as of the date received, (b) if delivered by a nationally recognized overnight delivery service, the next Business Day after being deposited with such delivery service for next Business Day delivery, or (c) if sent via facsimile, electronic mail in portable document format (pdf), or similar electronic transmission with a hard copy to follow and such form of address is specifically designated and permitted by a Party by listing such address (i.e., e-mail address or fax number) below, then as of the date received, to such Party at its address set forth below (or such other address as it may from time to time designate in writing to the other Parties hereto):

Section 6.9. Entire Agreement. This Agreement (including all of the exhibits and schedules hereto), the Confidentiality Agreement, the Transaction Documents, and the other specified reports, agreements, instruments and documents which are executed and delivered among the Parties hereto at or in connection with the Closing, shall constitute the entire agreement between the Parties hereto with respect to the subject matter hereof and supersede all prior agreements and understandings between the Parties with respect to such subject matter.

Section 6.10. Interpretation.

(a) When a reference is made to an Article, Section, Exhibit or a Schedule, such reference shall be deemed to refer to such Article, Section or Schedule of or to this Agreement unless otherwise indicated. Whenever the words “include,” “includes”, or “including” are used in this Agreement, they shall be deemed to be followed by the words “without limitation.” The phrase “ordinary course of business” shall include consistent with past practices of the Business without material deviation from the Company’s general past practices and experiences in the Business, including regarding the frequency and quantity of the matter in question where frequency or quantity is relevant to describing such practice. References to “dollars” or “$” are in U.S. dollars. The terms “hereof,” “herein,” “hereby,” “hereto” and derivative or similar words refer to this entire Agreement. The phrase “made available” means the referenced document (i) was physically or otherwise delivered (including, but not limited to, delivery via electronic media, such as a .pdf attachment to an email or a faxed document) to the Buyer or its agents at any time prior to the execution of this Agreement, or (ii) was posted and accessible to the Buyer and its agents in the electronic data room for this transaction no less than three Business Days prior to the date of this Agreement and remained so through the date of this Agreement.

(b) This Agreement was prepared jointly by the Parties hereto, each of which has respectively retained legal counsel, and no rule that ambiguities or other aspects hereof be construed against the drafter will have any application in its construction or interpretation.

Section 6.11. Waiver and Amendment. This Agreement may be amended or modified only by a written mutual agreement executed by duly authorized representatives of the respective

Parties (that is, only by a written mutual agreement executed and delivered by the Buyer, the Company and the Sellers respectively to the other Parties) and evidence of execution shall be delivered to each of the other Parties hereto. Any condition or performance due pursuant to the terms of this Agreement may be waived only by a written instrument specifically identifying the condition or performance which is waived, such waiver shall be executed by all Parties for whom such condition or performance would constitute any benefit, and such written waiver shall be delivered by such waiving Parties to all other Parties so as to effect notice of the same in accordance with the notice provisions of this Agreement. Any amendment, modification, or supplement to this Agreement affected in accordance with this section shall be binding on all Parties hereto, however, a waiver shall not require the consent of any Party for whom the waived condition or performance constitutes no benefit. No waiver or failure to insist upon strict compliance with any obligations, covenant, agreement or condition shall operate as a waiver of or estoppel with respect to any subsequent condition or performance due.

Section 6.12. Third-Party Beneficiaries. Except as otherwise specifically set forth in this Agreement, this Agreement is for the sole benefit of the Parties hereto and their permitted assigns, and nothing herein express or implied shall give or be construed to give to any Person, other than the Parties hereto, and such permitted assigns, any legal or equitable rights hereunder, except that the Buyer Parties are intended third party beneficiaries of Article VI.

Section 6.13. Severability. If any provision of this Agreement or the application of any such provision to any Person or circumstance shall be held invalid, illegal, or unenforceable in any respect by a court of competent jurisdiction, such invalidity, illegality or unenforceability shall not affect any other provision hereof or such provision to any other Person or circumstance or in any other jurisdiction.

Section 6.14. Counterparts; Facsimile Signatures. This Agreement may be executed in one or more counterpart signature pages, each of which will be deemed to be an original copy of this Agreement and all of which, when taken together, will be deemed to constitute one and the same agreement, which shall be binding upon all of the Parties hereto notwithstanding the fact that all Parties are not a signatory to the same counterpart. The exchange of copies of this Agreement and of signature pages by facsimile transmission, by electronic mail in “portable document format” (“.pdf”) form, or by any other electronic means intended to preserve the original graphic and pictorial appearance of a document, will have the same effect as physical delivery of the paper document bearing an original signature.

Section 6.15. Specific Performance. The Sellers acknowledge and agree that Buyer would be irreparably harmed if any of the provisions of this Agreement are not performed in accordance with their specific terms and that any material breach of this Agreement by any Seller or the Company could not be adequately compensated in all cases by monetary damages alone. Accordingly, the Sellers and the Company agree that, in addition to any other right or remedy to which Buyer may be entitled at law or in equity, Buyer shall be entitled to enforce any provision of this Agreement by a decree of specific performance and to obtain temporary, preliminary, and permanent injunctive relief to prevent breaches or threatened breaches, without posting any bond or giving any other undertaking.

Section 6.16. Non-Recourse. This Agreement may only be enforced against, and any Action based upon, arising out of, or related to this Agreement or the Transaction Documents, or the negotiation, execution or performance of this Agreement or the other Transaction Documents, may only be brought against the entities that are expressly named as Parties hereto and then only with respect to the specific obligations set forth in this Agreement or the Transaction Documents with respect to such Party. Except to the extent a named Party to this Agreement or the other Transaction Documents (and then only to the extent of the specific obligations undertaken by such named party in this Agreement or the other Transaction Documents and not otherwise), no past, present or future director, officer, employee, incorporator, manager, member, partner, stockholder, Affiliate, agent, attorney or other representative of any Party or of any Affiliate of any Party, or any of their successors or permitted assigns, shall have any liability for any obligations or liabilities of any Party under this Agreement or any other Transaction Documents or for any Action based on, in respect of or by reason of the transactions contemplated hereby or thereby. The provisions of this Section 6.16 are intended to be for the benefit of, and enforceable by, the directors, officers, employees, incorporators, managers, members, partners, stockholders, Affiliates, agents, attorneys or other representatives of the Parties hereto, and each such person shall be a third party beneficiary of this Section 6.16.

Section 6.17. Sellers’ Representative. By execution of this Agreement, the Sellers hereby irrevocably and unconditionally appoint Nephron Pharmaceuticals Corporation as the Sellers’ Representative of all Sellers, as the attorney-in-fact for and on behalf of each such Seller, and irrevocably agree that the taking by the Sellers’ Representative of any and all actions and the making of any decisions required or permitted to be taken by it or by a Seller under this Agreement or any Transaction Documents to which the Sellers are a party are hereby authorized and approved in all respects, including without limitation the exercise of the power to (i) receive from Buyer and disburse to Sellers any payments constituting any part of the Purchase Price and receive and disburse from and to any Party or any Third Party which may be contemplated to be made under the Transaction Documents, (ii) agree to, negotiate, enter into settlements and compromises of and comply with orders of courts with respect to any indemnification claims or disputes, (iii) resolve any indemnification claims or disputes, and (iv) take all actions necessary in the judgment of the Sellers’ Representative for the accomplishment of the other terms, conditions and limitations of this Agreement and the Transaction Documents.
