STOCK PURCHASE AGREEMENT

This Agreement (the “Agreement”) is made and entered into as of January 8, 2007 by and among Blue Acquisition Corp., a Delaware corporation (“Buyer”), SkyePharma Holding, Inc. (“Seller”), a Delaware corporation and a wholly owned subsidiary of SkyePharma PLC, a company incorporated under the laws of England and Wales (“Parent”), and SkyePharma, Inc., a California corporation and wholly owned subsidiary of Seller (the “Company”).

Recitals

Seller is the direct owner of all issued and outstanding shares of capital stock of the Company (the “Shares”). Buyer desires to purchase, and Seller desires to sell, the Shares for the consideration set forth below, on the terms and subject to the conditions set forth in this Agreement.

In order to induce Buyer to enter into this Agreement and consummate the transactions contemplated hereunder, concurrently herewith, Parent has executed and delivered to Buyer a Parent Guaranty Agreement in the form attached hereto as Exhibit A (the “Parent Guaranty”).

In order to induce Seller to enter into this Agreement and consummate the transactions contemplated hereunder, concurrently herewith, Buyer has delivered the Commitment Letters (defined below) naming Seller as a third party beneficiary thereto.

NOW, THEREFORE, in consideration of the premises, and the mutual representations, warranties, covenants and agreements set forth in this Agreement, and for other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, and intending to be legally bound, Buyer, Seller and the Company hereby agree as follows:

ARTICLE I

PURCHASE AND SALE OF THE SHARES

1.1. Purchase of the Shares from Seller. Upon the terms and subject to the conditions set forth in this Agreement, at the Closing, Seller shall sell, transfer, convey, assign and deliver to Buyer, and Buyer shall purchase, acquire and accept from Seller, all of the Shares, free and clear of all Encumbrances. At the Closing, Seller shall deliver to Buyer certificates evidencing all of the Shares duly endorsed in blank or with stock powers duly executed by Seller. Buyer acknowledges and agrees that in acquiring the Shares, Buyer is not acquiring any rights, title or interest in, to and under (i) the names “SkyePharma USA, Inc.,” “SkyePharma, Inc.,” “SkyePharma,” “SkyePharma USA,” “Skye, Inc.” “Skye,” “Skye USA,” variations and derivatives thereof and any other logos or trademarks, trade names or service marks of the Company (collectively, the “Names”) and (ii) the Excluded Assets (as defined below) of the Company that, pursuant to Section 5.11, are to be transferred from the Company to Seller and/or Affiliates of Seller (other than the Company) prior to the Closing.

1.2. Further Assurances. At any time and from time to time after the Closing, at Buyer’s request and without further consideration, Seller shall (and shall cause each of its Affiliates and each of its Affiliates’ respective directors, officers and employees to) promptly

EXECUTION COPY

execute and deliver such instruments of sale, transfer, conveyance, assignment and confirmation, and take all such other action as Buyer may reasonably request, to transfer, convey and assign to Buyer, and to confirm Buyer’s title to, all of the Shares, to put Buyer (through the ownership of the Shares) in effective operating control of the assets, properties and business of the Company, to assist Buyer in exercising all rights with respect thereto, and otherwise to carry out the purpose and intent of this Agreement.

1.3. Purchase Price. The Base Purchase Price to be paid by Buyer to Seller shall be twenty million dollars ($20,000,000), subject to adjustment pursuant to Section 1.5. The Base Purchase Price shall be payable in the manner described in Section 1.4.

1.4. Payment of Base Purchase Price. At the Closing, Buyer shall (a) pay to Seller the Base Purchase Price, minus the Escrow Amount, in cash, by wire transfer of immediately available funds to an account designated by Seller, and (b) deliver to the Escrow Agent the Escrow Amount for deposit into the Escrow Fund, such amount and fund to be held in accordance with the provisions of Sections 1.5 and 5.15 and Article VIII of this Agreement and the Escrow Agreement.

1.5. Post-Closing Adjustments. The Base Purchase Price shall be subject to adjustment after the Closing Date as follows:

(a) Set forth in Column X of the spreadsheet attached in Schedule 1.5(a)(i) is a statement compiling certain asset and liability accounts of the Company as of November 24, 2006 (the “Target Net Assets Statement”). The Target Net Assets Statement was prepared on the same basis as the Most Recent Net Assets Statement, with the eliminations and adjustments set forth in Schedule 6.12 and the further eliminations set forth in Schedule 1.5(a)(ii). The Target Net Assets Statement includes a “net assets value” of the Company of $[**] (the “Net Assets Target”). No later than 5 p.m. Pacific Standard Time on the tenth (10^th) business day after the Closing Date, Seller shall deliver to Buyer a compilation of the same asset and liability accounts included in the Target Net Assets Statement, but prepared as of the Closing Date (the “Draft Closing Net Assets Statement”), which shall be prepared by Seller on the same basis as the Most Recent Net Assets Statement, applied on a basis consistent with the past accounting practices of the Company, with the eliminations and adjustment set forth in Schedule 6.12 and the further eliminations set forth in Schedule 1.5(a)(ii). Solely for the avoidance of doubt, neither the Draft Closing Net Assets Statement nor the Final Closing Net Assets Statement will reflect any writedown or fair value adjustment of assets or any provision for liabilities arising from the termination of the Endo Agreement.

(b) Buyer shall deliver to Seller, no later than 6 p.m. Pacific Standard Time on the Objection Deadline Date, either a notice indicating that Buyer accepts the Draft Closing Net Assets Statement or a statement in reasonable detail describing its objections (if any) to the Draft Closing Net Assets Statement and the grounds for such objections (an “Objection Statement”). If Buyer delivers to Seller a notice accepting the Draft Closing Net Assets Statement, or Buyer does not deliver a timely Objection Statement by 6 p.m. Pacific Standard Time on the Objection Deadline Date, then, effective as of either the date of delivery of such notice of acceptance or as of the close of business on the Objection Deadline Date, the Draft Closing Net Assets Statement shall be deemed to be the final compilation of the asset and liability accounts included in the Target Net Assets Statement, measured and calculated as of the Closing Date (the “Final Closing Net Assets Statement”). If Buyer timely objects to the Draft Closing Net Assets Statement, such objections shall be resolved as follows:

(i) Buyer and Seller shall seek in good faith to resolve such objections. Each Party shall provide the other Parties with reasonable access to its records, personnel and supporting documentation relating to the Draft Closing Net Assets Statements and the items giving rise to the Objection Statement until such time as the Final Closing Net Assets Statement is determined.

EXECUTION COPY

(ii) If Buyer and Seller do not reach a resolution of all objections set forth in Buyer’s Objection Statement within thirty (30) days after delivery of such Objection Statement, Buyer and Seller shall, within thirty (30) days following the expiration of such 30-day period, engage the Accountant, pursuant to an engagement agreement executed by Buyer, Seller and the Accountant, to resolve the Unresolved Objections.

(iii) Buyer and Seller shall jointly submit to the Accountant, within ten (10) days after the date of the engagement of the Accountant (as evidenced by the date of the engagement agreement), a copy of the Draft Closing Net Assets Statement, a copy of the Objection Statement, and a statement setting forth the resolution of any objections agreed to by Buyer and Seller. Each of Buyer and Seller shall submit to the Accountant (with a copy delivered to the other Party on the same day), within thirty (30) days after the date of the engagement of the Accountant, a memorandum (which may include supporting exhibits) setting forth their respective positions on the Unresolved Objections. Each of Buyer and Seller may (but shall not be required to) submit to the Accountant (with a copy delivered to the other Party on the same day), within forty five (45) days after the date of the engagement of the Accountant, a memorandum responding to the initial memorandum submitted to the Accountant by the other Party. Unless requested by the Accountant in writing, neither Party may present any additional information or arguments to the Accountant, either orally or in writing.

(iv) Within ninety (90) days after the date of its engagement hereunder, the Accountant shall determine whether the objections raised by Buyer are appropriate and shall issue a ruling which shall include a compilation of the accounts included (or required to be included) in the Draft Closing Net Assets Statement as adjusted pursuant to any resolutions to objections agreed upon by Buyer and Seller and pursuant to the Accountant’s resolution of the Unresolved Objections. Such statement shall be Final Closing Net Assets Statement.

(v) The resolution by the Accountant of the Unresolved Objections shall be conclusive and binding upon Buyer and Seller. Buyer and Seller agree that the procedure set forth in this Section 1.5(b) for resolving disputes with respect to the Draft Closing Net Assets Statement shall be the sole and exclusive method for resolving any such disputes; provided that this provision shall not prohibit either Party from instituting litigation to enforce the procedures and deadlines set forth herein or to enforce rulings of the Accountant.

(vi) Buyer and Seller shall share equally the fees and expenses of the Accountant.

EXECUTION COPY

(c) Immediately following the Objection Deadline Date, if a timely Objection Statement is not delivered, or upon notification by Buyer to Seller that no objection to the Draft Closing Net Assets Statement will be made, or immediately upon final resolution of any dispute in connection with the determination of the Final Closing Net Assets Statement pursuant to this Section 1.5, the Adjusted Purchase Price shall be determined as follows:

(d) If the “net assets value” as shown on the Final Closing Net Assets Statement is more than [**] dollars ($[**]) less than “net assets value” as shown in the Target Net Assets Statement, the deficiency in excess of such $[**] amount shall be deducted from the Base Purchase Price to obtain the Adjusted Purchase Price, and shall be paid by Seller to Buyer from the following sources in the following manner and priority: first, by payment in cash to Buyer by the Escrow Agent from the Escrow Fund, to the extent funds are available in the Escrow Fund, and thereafter, by payment in cash to Buyer by Seller, from funds of Seller, to an account designated by Buyer, in each case by wire transfer of immediately available funds within two (2) business days after such determination.

(e) For purposes of implementing the provisions of Section 1.5 and Section 8.1(h), each Party shall have reasonable access, upon request, during normal business hours and with reasonable advance notice, to the books, records and personnel of the other Parties to the extent reasonably relevant to the determination either of the Draft Closing Net Assets Statement and the Final Closing Net Assets Statement and the resolution of any Objection Statement and Unresolved Objections (in the case of Section 1.5) or the Designated Amounts and the invoices submitted as relating thereto (in the case of Section 8.1(h)).

1.6. Escrow Account. The Escrow Amount shall be delivered to the Escrow Agent for deposit into a fund (the “Escrow Fund”) that shall be held by the Escrow Agent under the terms of the Escrow Agreement for the purpose of securing the indemnification obligations of Seller pursuant to Article VIII and Section 5.15, any adjustment to the Base Purchase Price pursuant to Section 1.5, and any reimbursement obligation of Parent or Seller with respect to payments under the Stay Incentive Agreements under Section 5.16. The Escrow Fund shall be held as a trust fund and shall not be subject to any lien, attachment, trustee process or any other judicial process of any creditor of any Party, and shall be held and disbursed solely for the purposes and in accordance with the terms of the Escrow Agreement.

1.7. Earn-Out. Following the Closing, the Company shall pay to Seller the amounts set forth in Schedule 1.7, minus any amounts determined to be due to Buyer pursuant to Section 1.5 or Section 5.16, or pursuant to Article VIII or Section 5.15 (only to the extent of the Cap set forth in Section 8.5), and not otherwise paid to Seller before any such amounts on Schedule 1.7 (if any) become payable pursuant to Schedule 1.7.

1.8. The Closing.

(a) The Closing shall take place at the offices of Wilmer Cutler Pickering Hale and Dorr LLP, 1117 California Avenue, Palo Alto, California commencing at 9:00 a.m. Pacific Standard Time on the date within two (2) business days after the satisfaction or waiver of all of the conditions to the obligations of the Parties to consummate the transactions contemplated hereby (excluding the delivery at the Closing of any of the documents set forth in Articles VI and VII), or such other date as may be mutually agreeable to the Parties. The transfer of the Shares by Seller to Buyer shall be deemed to occur at 9:00 a.m. Pacific Standard Time, on the Closing Date.

(ii) Seller shall then deliver to Buyer certificates evidencing all of the Shares duly endorsed in blank or with stock powers duly executed by Seller; and

(iii) Buyer shall then pay the amount set forth in Section 1.4(a), in the manner prescribed therein.

1.9. Allocation of Payments.

If the Dispute is not resolved within such 30-day period, the Indemnifying Party and the Indemnified Party shall submit the Dispute to binding arbitration in accordance with the provisions of Section 8.3(e).

(a) Except as otherwise expressly set forth herein, Seller shall not be liable under this Article VIII unless and until the aggregate Losses for which Seller would otherwise be liable under this Article VIII exceed [**] dollars ($[**]) (the “Threshold Amount”) (at which point Seller shall become liable for all aggregate Losses subject to indemnification under this Article VIII, and not just amounts in excess of the Threshold Amount; provided that the limitation set forth in this sentence shall not apply to a claim pursuant to Section 8.1(a) relating to a breach of the representations and warranties set forth in Sections 2.1, 2.2 or 2.5 or Sections 3.1, 3.2, 3.3, 3.13, 3.23(g), or 3.30 or pursuant to Section 8.1(f) (as to which the Threshold Amount shall not apply), or to a claim pursuant to Section 8.1(d) with respect to matters disclosed in Schedule 8.1(d) (as to which the Threshold Amount shall be deemed to be [**] dollars ($[**])).

(b) Notwithstanding anything to the contrary herein, Buyer shall not be liable under this Article VIII unless and until the aggregate Losses for which Buyer would otherwise be liable under this Article VIII exceed the Threshold Amount (at which point Buyer shall become liable for all aggregate Losses subject to indemnification under this Article VIII, and not just amounts in excess of the Threshold Amount); provided that the limitation set forth in this sentence shall not apply to a claim pursuant to Section 8.1(a) relating to a breach of the representations and warranties set forth in Sections 4.1, 4.2, 4.3, 4.4 or 4.6 or a claim for payment of any amount due pursuant to Article I. For purposes solely of this Article VIII, all representations and warranties (if any) of Buyer in Article IV with materiality limitations, qualifications or baskets shall be construed without respect to any materiality limitation, materiality qualification or materiality basket, as if the term “material” and any reference to “Buyer Material Adverse Effect” (and variations thereof) were omitted from such representations and warranties.

(c) The Escrow Agreement is intended to secure the indemnification obligations of Seller under Article VIII and Section 5.15, the adjustment obligations of Seller under Section 1.5, and the obligations of Parent under the Parent Guaranty. However, the rights of Buyer under this Article VIII, Section 5.15, and Section 1.5 shall not be limited to the Escrow Fund nor shall the Escrow Agreement be the exclusive means for Buyer to enforce such rights; provided that, except as otherwise expressly permitted by this Agreement, Buyer shall not attempt to collect any Losses directly from Seller pursuant to this Article VIII or Section 5.15 unless no remaining portion of the Escrow Fund is held in escrow pursuant to the Escrow Agreement and no portion of the Earn-Out is available to satisfy such Losses; and provided further that, notwithstanding anything to the contrary herein, in no event shall the aggregate liability of Seller pursuant to this Article VIII and Section 5.15 (and the aggregate liability of Parent pursuant to the Parent Guaranty insofar as such guaranty relates to the liabilities of Seller pursuant to this Article VIII), taken together, exceed the Cap.

For the avoidance of doubt, nothing in this Section 8.5(d) is intended to limit the Partiers’ rights to recover purchase price adjustments pursuant to Section 1.5 or any rights of offset and set-off pursuant to Section 1.4 (b).

(e) Neither Seller nor any of its subsidiaries shall have any right of contribution against the Company with respect to any breach of or inaccuracy in any representation and warranty of the Company or any breach by the Company of any of its covenants or agreements.

(f) In the event that adjustment has been made pursuant to Section 1.5 for any item that also constitutes an indemnifiable Loss pursuant to this Article VIII arising out of a breach of Seller’s representations and warranties in Section 3.14 or Section 3.16, Buyer shall not be entitled to recover indemnification under this Article VIII for any amount that Buyer has theretofore recovered as an adjustment to the Base Purchase Price pursuant to Section 1.5.

ARTICLE IX

CERTAIN POST-CLOSING AGREEMENTS

Seller agrees that from and after the Closing Date:

9.1. Proprietary Information.

(a) Seller shall (and shall cause each of its Affiliates to) hold in confidence and shall use its (and their) commercially reasonable efforts to have all officers, directors and personnel who continue after the Closing to be employed by Seller or any Affiliate of Seller to hold in confidence all knowledge and information of a secret or confidential nature with respect to the business of the Company and not to disclose, publish or make use of the same without the consent of Buyer, except as required by law (in which case Seller shall provide reasonable advance notice of such proposed disclosure and shall cooperate with Buyer and the Company, at their expense, in seeking an appropriate protective order or other confidentiality assurances) and except to the extent that such information shall have become public knowledge other than by breach of this Agreement by Seller.

(b) If (i) the employment of an officer, director or other employee of Seller or any Affiliate thereof, to whom secret or confidential knowledge or information concerning the business of the Company has been disclosed, is terminated and (ii) such individual is subject to an obligation to maintain such knowledge or information in confidence after such termination, Seller shall, upon request by Buyer, take all reasonable steps at their expense to enforce such confidentiality obligation in the event of an actual or threatened breach thereof. Any legal counsel retained by Seller in connection with any such enforcement or attempted enforcement shall be selected by Seller, but shall be subject to the approval of Buyer, which approval shall not be unreasonably withheld.

(c) Seller agrees that the remedy at law for any breach of this Section 9.1 would be inadequate and that Buyer shall be entitled to injunctive relief in addition to any other remedy it may have upon breach of any provision of this Section 9.1.

9.2. No Solicitation of Former Employees. Except as provided by law, for a period of [**] ([**]) years after the Closing Date, Seller shall not (and shall cause its subsidiaries and Affiliates not to) directly or indirectly solicit, induce or encourage any person who was an employee (other than secretarial and clerical staff) of either the Company on the date hereof or the Closing Date to terminate his employment with Buyer (or the Company, as the case may be) or to become an employee of Seller or any of its subsidiaries or Affiliates; provided, that nothing in this Section 9.2 shall be construed to prohibit Seller from placing advertisements in publications of general circulation that are not directly specifically at employees of Buyer or the Company.

9.3. Non-Competition Agreement.

(a) For a period of [**] ([**]) years after the Closing Date (the “Restricted Period”), neither Seller nor any of its subsidiaries or Affiliates shall (and Seller shall procure that Parent shall not), either directly or indirectly through any subsidiary or Affiliate, develop,

- 55 -

EXECUTION COPY

manufacture, market or sell, anywhere in the world (including anywhere in the United States or any country in North America, Japan or any country in Asia, Australia, New Zealand, England or any country in Europe), (i) any sustained-release bupivacaine-based product for use in pain management, or (ii) any sustained-release opioid-based product for use in pain management (other than the non-injectable sustained-release naproxen-hydrocodone combination products currently under development at the Company), or (iii) any sustained-release cytarabine-based product, or (iv) any sustained-release Biologics Product (as defined in Schedule 1.7). For purposes of this provision, “sustained-release” shall mean release such that the intended dosing or use is for more than twelve (12) hours. For a period of [**] ([**]) years after the Closing Date, Seller shall not, and shall procure that Parent and its Affiliates shall not, solicit any drug development business with respect to any of the substances listed in Column A of Schedule 9.3(a) from any of the entities named or otherwise identified opposite such substance in Column B thereof.

(b) Seller and Buyer agree that the market for the Company’s products is worldwide, that development cycles for products such as the Company’s products are lengthy, and that duration and geographic scope of the non-competition provision set forth in this Section 9.3 are reasonable. In the event that any court of competent jurisdiction determines that the duration or the geographic scope, or both, are unreasonable and that such provision is to that extent unenforceable, Seller and Buyer agree that the provision shall remain in full force and effect for the greatest time period and in the greatest area that would not render it unenforceable. Seller and Buyer intend that this non-competition provision shall be deemed to be a series of separate covenants, one for each and every county of each and every state of the United States of America and each and every country and political subdivision of each and every country outside the United States of America where this provision is intended to be effective. Seller agrees that damages are an inadequate remedy for any breach of this provision and that Buyer shall, whether or not it is pursuing any potential remedies at law, be entitled to equitable relief in the form of preliminary and permanent injunctions without bond or other security upon any actual or threatened breach of this non-competition provision.

(c) Notwithstanding the foregoing provisions: (i) nothing herein shall be construed to prevent or prohibit the acquisition of Parent as a whole by any unaffiliated acquiror or to subject the other operations of any such acquiror to the restrictions of this Section 9.3 (it being understood and agreed that the provisions of this Section 9.3 shall continue to apply to the operations of Seller and the entities that prior to the consummation of such an acquisition are Affiliates of Seller (including Parent and its Affiliates)); and (ii) in the event that Parent acquires a company whose assets and operations would violate the provisions of this Section 9.3, neither Parent nor Seller shall be deemed to be in violation of this Section 9.3 as long as Parent shall have divested, spun off or otherwise ceased to own or operate such assets and operations within one hundred eighty (180) days after the consummation of such acquisition.

9.4. Further Assurances. If at any time before the Closing or during the three (3) year period following the Closing any Omitted IP is discovered, Seller shall (and shall procure that Parent and its Affiliates shall), at Seller’s sole expense, (a) assign, transfer and deliver all right, title and interest held by Seller (or by Parent or any of its Affiliates) in, to and under such Omitted IP to the Company at the Closing or as soon as reasonably practicable after the Closing,

- 56 -

EXECUTION COPY

but in any case, within thirty (30) days after such Omitted IP is discovered, and (b) take such further action reasonably requested by the Company or Buyer in order to more fully vest and record title in and to such Omitted IP the name of the Company. Subject to Seller’s compliance with this Section 9.4, and provided that the omission of such Omitted IP is inadvertent, Buyer agrees and acknowledges that Buyer’s rights under this Section 9.4 shall be its sole and exclusive remedy for a breach of the representations and warranties set forth in Section 3.13(g), where such breach arises solely from the failure of the Company to own such Omitted IP as of the Closing. Effective upon (and subject to) the assignment to the Company of any Licensed-Back Omitted IP in accordance with this Section 9.4, the Company hereby grants to Seller and its Affiliates a non-exclusive, royalty-free, perpetual, irrevocable, worldwide license, with the right to sublicense, under any and all such Licensed-Back Omitted IP for use by Seller and its Affiliates subject to the provisions of Section 9.3.

1.1 Certain Definitions. Solely for purposes of this Schedule 1.7, the following terms shall have the meanings set forth below. All other capitalized terms used in this Schedule 1.7 (other than names and proper nouns) shall have the meanings ascribed to such terms in the Stock Purchase Agreement to which this Schedule 1.7 is attached.

(a) “Biologics Products” means a pharmaceutical composition having one or more of the following active ingredients: follicle stimulating hormone, Biosphere-encapsulated human growth hormone, interferon-alpha, erythropoietin, and granulocyte colony stimulating factor.

(b) “DepoBupivacaine” means a pharmaceutical composition having bupivacaine as an active ingredient encapsulated with the Company’s multivesicular liposomes technology to provide sustained release.

EXECUTION COPY

(e) “Major EU Country” means United Kingdom, France, Germany, Italy and Spain or any of them.

(f) “Marketing Authorization” means, with respect to a country, all approvals, licenses, registrations and regulatory authorizations required to market and sell a Product in such country as granted by the Relevant Regulatory Authority. For countries where the Relevant Regulatory Authority approval is required for pricing or reimbursement for Product prior to undertaking sales or marketing, “Marketing Authorization” shall not be deemed to occur until such pricing or reimbursement approval is obtained.

(g) “Net Sales” means total gross sales of each Product invoiced and actually collected by the Company, its Affiliates or any licensee of the Company (or a further sublicense of such licensee) to unaffiliated third parties, less the following amounts actually deducted or allowed: (i) transport, freight and insurance costs; (ii) sales and excise taxes and duties; (iii) normal and customary trade, quantity and cash discounts and rebates; (iv) refunds and chargebacks; (v) actual rebates and credits or allowances allowed to customers in respect thereof; and (vi) amounts repaid or credited for actually returned or recalled Products.

In the event a Product is sold in combination with, or contains, one or more other active ingredients which are not the subject of this Agreement (as used in this definition of Net Sales, a “Combination”), then the gross amount invoiced for that product shall be calculated by multiplying the gross amount invoiced for such Combination by the fraction A/(A+B), where “A” is the gross amount invoiced for the Product sold separately and “B” is the gross amount invoiced for the other active ingredient(s) sold separately; provided, however, for the avoidance of doubt, in the case of DepoBupivacaine, a Product will not qualify as a “Combination” under this provision due to the use or inclusion of bupivacaine as another active ingredient in such product, regardless of the form or formulation that such bupivacaine may be included or otherwise found within DepoBupivacaine. In the event that the other active ingredient is not sold separately, then the gross amount invoiced for that product shall be calculated by multiplying the gross amount invoiced for the Combination by the fraction A/C, where “A” is the gross invoice amount for the Product, if sold separately, and “C” is the gross invoice amount for the Combination. In the event that no such separate sales are made, Net Sales for royalty determination shall be determined by the Parties in good faith.

(i) “Product” means DepoBupivacaine or any of the Biologics Products.

1.2 Diligence; Non-Circumvention; Periodic Reports.

(a) During the Restricted Period, Buyer will cause the Company to use good faith efforts toward the development and commercialization of DepoBupivacaine in the United States and a Major EU Market Country; provided, however, that in all decisions related to such development and commercialization efforts the Company may take into account the factors of safety and efficacy, risk profile, profitability, product profile, competitive landscape, difficulty in developing or manufacturing the Product, competitiveness of alternative products, the patent or other proprietary position of the Product and/or third party products, the regulatory structure involved and the potential, and current corporate goals and priorities; and provided further that the Company may cease or reduce such development and commercialization efforts and funding for any reason other than for the sole or primary purpose of depriving Seller of payments it would otherwise be entitled to received under this Schedule 1.7 if the Board of Directors of the Company, in the exercise of its good faith business judgment, determines that it is in the best interests of the Company and its stockholders to do so.

(b) [**] times each year until the end the Payment Period, as long as any of the DepoBupivacaine Milestone Payments remains unpaid and there is a reasonable expectation that such payment will become payable in the future, not later than the last day of the months of [**], Buyer shall cause the Company to furnish Seller with a report summarizing the development status of DepoBupivacaine and the Biologics Products.

(b) All payments under this Schedule 1.7 shall, for sales made in the United States, be made in U.S. dollars, and shall, for all other sales worldwide, be made in Euros, in each case via wire transfer of immediately available funds or check as directed by Seller from time to time. Payments shall be without deduction of exchange, collection, transfer or other charges. Conversion into U.S. dollars and Euros, as appropriate, shall be made at the exchange rate on the applicable payment date as reported in The Wall Street Journal (East Coast edition) for the immediately preceding business day. Seller shall be entitled to interest on all late payments. Such interest shall be calculated from the date such amount was due until the date such amount is actually paid, at the prime rate of interest reported in The Wall Street Journal (East Coast Edition) for the date such amount was due plus [**]%.

(c) The DepoBupivacaine Percentage Payments shall be made in consideration for the covenant not to compete set forth in Section 9.3(a)(i) and the Biologics Products Percentage Payments shall be made in consideration for the covenant not to compete set forth in Section 9.3(a)(iv).

(d) If after the expiration of the Restricted Period, Parent or any of its Affiliates engages in the development, manufacture, marketing or sale of any product within the scope of Section 9.3(a)(i), (ii) or (iii) anywhere in the world, the obligation to make payments under Section 1.7 and this Schedule 1.7 shall automatically and immediately cease. If after the expiration of the Restricted Period, Parent or any of its Affiliates engages in the development, manufacture, marketing or sale of any product within the scope of Section 9.3(a)(iv) anywhere in the world, and the Company is then selling or thereafter sells a Biologics Product, the obligation to make payments under Section 1.7 and this Schedule 1.7 shall automatically and immediately cease.

(e) Notwithstanding the foregoing, if during the Restricted Period the Company markets and sells a product as a substitute for DepoBupivacaine, the obligation to make DepoBupivacaine Percentage Payments under Section 1.7 and this Schedule 1.7 shall automatically and immediately cease and terminate and, in lieu thereof, the aggregate sales of such substitute product shall be counted toward the achievement of the thresholds for the DepoBupivacaine Milestone Payments.

(f) Until the end of the Payment Period, as long as there is a reasonable expectation that a payment pursuant to this Schedule 1.7 will become payable in the future, if the Company or any subsidiary or majority owner of the Company proposes to sell, assign or transfer substantially all rights to any of the Products to a third party, the Company shall, as a condition of such sale, assignment or transfer, require such third party to assume the obligations of the Company pursuant to this Schedule 1.7 with respect to such Product.

1.4 Records Retention. Commencing with the First Commercial Sale of a Product, Buyer shall keep, and shall require its relevant Affiliates to keep, and shall use commercially reasonable efforts to include terms in its licenses with licensees requiring its licensees to keep, complete and accurate records pertaining to the sale of Product for a period of three (3) calendar years after the year in which such sales occurred and in sufficient detail to permit Seller to confirm the accuracy of the Percentage Payments paid by Buyer pursuant to this Schedule 1.7.

1.5 Audits.

(a) At the request and expense of Seller, Buyer (and its Affiliates, if applicable) shall permit an independent, certified public accountant appointed by Seller and reasonably acceptable to Buyer, at reasonable times and upon reasonable written notice not more than once in each calendar year, to examine such records as may be necessary for the sole purpose of verifying the calculation and reporting of Net Sales and the correctness of any Percentage Payment or other payment made under this Schedule 1.7 for any period within the preceding [**] ([**]) calendar years. Said accountant shall not disclose to Seller or any other person any information, except that such accountant may disclose to Seller the fact of a deficiency, the lack of a deficiency or any overpayment, and the degree thereof, including the dollar amount. All results of any such examination shall be made available to Buyer.

(b) In the event that any audit reveals an overpayment or an underpayment in the amount of any payments that should have been paid by Buyer to Seller, then the overpayment or underpayment amount, as the case may be, shall be paid within thirty (30) days after receipt of the final audit report, plus interest thereon. Such interest shall be calculated in accordance with Section 1.3(b) of this Schedule 1.7. In addition, if the underpayment is in excess of [**] percent ([**]%) of the amount that actually should have been paid, then Buyer shall reimburse Seller for the reasonable cost of such audit. This Section 1.5(b) of this Schedule 1.7 sets forth the Parties’ sole and exclusive liability for any such overpayment or underpayment.

(c) Except in the case of circumstances which would have prevented an error or anomaly from being disclosed during an audit performed under this Section 1.5 of this Schedule 1.7 such as fraud, misrepresentation or other willful misconduct or gross negligence to provide accurate information, upon the expiration of three (3) years following the end of any calendar year, the calculation of Percentage Payments payable with respect to such year will be binding and conclusive upon each Party and Buyer will be released from any liability or accountability with respect to Percentage Payments for such calendar year.

1.6 Force Majeure. Other than with respect to obligations for the payment of money, neither Party shall be held liable or responsible to the other Party nor be deemed to be in default under, or in breach of any provision of, this Schedule 1.7 for failure or delay in fulfilling or performing any obligation of this Schedule 1.7 when such failure or delay is due to Force Majeure. In such event, Seller or Buyer, as the case may be, shall immediately notify the other Party, with written notice to follow, of such inability and of the period for which such inability is expected to continue. The Party giving such notice shall thereupon be excused from such of its obligations under this Schedule 1.7 as it is thereby disabled from performing for so long as it is so disabled. Upon termination of a Force Majeure event, the performance of any suspended obligation or duty shall promptly recommence. To the extent possible, each Party shall use reasonable efforts to minimize the duration of any Force Majeure.
