In consideration of the representations, warranties and covenants herein contained, the Parties agree as follows.

ARTICLE I

1.1                                 Purchase and Sale of Assets.

(a)                                  Upon and subject to the terms and conditions of this Agreement, the Buyer shall purchase from the Seller, and the Seller shall sell, transfer, convey, assign and deliver to the Buyer, at the Closing, for the consideration specified below in this Article I, all right, title and interest in, to and under the Acquired Assets.

(b)                                 Notwithstanding the provisions of Section 1.1(a) or any other provision of this Agreement to the contrary, the Acquired Assets shall not include the Excluded Assets.

1.2                                 Assumption of Liabilities.

(a)                                  Upon and subject to the terms and conditions of this Agreement, the Buyer shall assume and become responsible for, from and after the Closing, the Assumed Liabilities.

(b)                                 Notwithstanding the terms of Section 1.2(a) or any other provision of this Agreement to the contrary, the Buyer shall not assume or become responsible for, and the Seller shall remain liable for, the Retained Liabilities.

1.3                                 Purchase Price.  The Purchase Price to be paid by the Buyer for the Acquired Assets shall be as follows:

(a)                                  On the Closing Date, the Buyer shall pay the Seller, by wire transfer of immediately available funds to an account designated by the Seller, $2,500,000 (the “Closing Date Payment”).

(b)                                 The Seller shall also be entitled to receive contingent milestone payments in the manner and on the terms and conditions set forth in Section 1.4.

1.4                                 Contingent Milestone Payments.  The Seller shall be entitled to receive additional consideration from the Buyer if any of the following conditions are satisfied:

(a)                                  The Buyer shall pay the Seller, by wire transfer of immediately available funds to an account designated by the Seller, $2,000,000 within 10 days following the completion and satisfaction of the Capabilities Build Milestone.  Notwithstanding the foregoing, in the event the entire Capabilities Build Milestone has not been satisfied on or before the second (2nd) anniversary of the Closing Date, the Buyer shall pay the Seller, by wire transfer of immediately available funds to an account designated by the Seller within 10 days following the second (2nd) anniversary of the Closing Date, (i) $[**] in the event Submilestone A of the Capabilities Build Milestone has been satisfied on or before such date or (ii) $[**] if both Submilestone A and Submilestone B of the Capabilities Build Milestone have been satisfied on or before such date; provided, however, that no such payment shall be due under clauses (i) or (ii) in the event the Primary Member’s employment with the Buyer has been terminated by the Buyer for Cause or has been terminated by the Primary Member without Good Reason (as each of  such terms is defined in the Employment Agreement of even date herewith by and between the Buyer and the Primary Member) on or before the second (2nd) anniversary of the Closing Date.

(b)                                 Provided that the M-Enoxaparin Milestone is reached within 15 years after the date of this Agreement, the Buyer shall issue to the Seller, within 90 days following the completion and satisfaction of the M-Enoxaparin Milestone, that number of shares of Buyer Common Stock (rounded to the nearest whole share) equal to $[**] divided by the Closing Value (the “Preliminary M-Enoxaparin Shares”); provided however that in the event the Issuance Value multiplied by the number of such Preliminary M-Enoxaparin Shares shall exceed $[**], then the number of shares of Buyer Common Stock to be issued to the Seller upon achievement of the M-Enoxaparin Milestone shall be reduced to such number of shares of Buyer Common Stock (rounded to the nearest whole share) equal to $[**] divided by the Issuance Value.

(c)                                  Provided that the Second Generic Product Milestone is reached within 15 years after the date of this Agreement, the Buyer shall issue to the Seller, within 90 days following the completion and satisfaction of the Second Generic Product Milestone, that number of shares of Buyer Common Stock (rounded to the nearest whole share) equal to $[**] divided by the Closing Value (the “Preliminary Second Generic Shares”); provided however that in the event the Issuance Value multiplied by the number of such Preliminary Second Generic Shares shall exceed $[**], then the number of shares of Buyer Common Stock to be issued to the Seller upon achievement of the Second Generic Product Milestone shall be reduced to such number of shares of Buyer Common Stock (rounded to the nearest whole share) equal to $[**] divided by the Issuance Value.

(d)                                 The Seller and the Primary Member agree and acknowledge that the Buyer may make from time to time such business decisions as it deems appropriate in the conduct of its business, including actions that may have an impact on the achievement of any Milestone, and the Seller and the Primary Member will have no right to claim any lost milestone consideration or other damages as a result of such decisions so long as the actions were not taken by the Buyer in bad faith or for the principal purpose of frustrating the provisions of this Section.  For the avoidance of doubt, the termination of the employment of the Primary Member with the Buyer for any reason (with or without Cause) shall not affect the achievement of the M-Enoxaparin Milestone or the Second Generic Product Milestone; viz., to the extent either of the Milestones are achieved then the Seller will receive the consideration set forth in this Section 1.4(b) and/or 1.4(c), respectively, regardless of whether the Primary Member is an employee of the Buyer at the time such Milestone is achieved.

2.14                           Legal Compliance.  The Seller is currently conducting, and has at all times since its formation conducted, the Acquired Business in compliance with each applicable law (including rules and regulations thereunder) of any federal, state, local or foreign government, or any Governmental Entity.  The Seller has not received any notice or communication from any Governmental Entity alleging noncompliance with any applicable law, rule or regulation related to the Acquired Business or Acquired Assets.  The Seller has not received any proceeds under the Small Business Technology Transfer grant listed in Section 2.10(xiii) of the Disclosure Schedule (the “Grant”). Until the Seller draws funding under the Grant, the Seller is not deemed to have accepted the Grant award and therefore has no obligations under the Grant terms and conditions.

10

2.15                           Permits.  Section 2.15 of the Disclosure Schedule sets forth a list of all Permits issued to or held by the Seller relating to the Acquired Business or Acquired Assets.  Such listed Permits are the only Permits that are required for the Seller to conduct the Acquired Business and Acquired Assets as presently conducted.  Each such Permit is in full force and effect; the Seller is in compliance with the terms of each such Permit; and, to the knowledge of the Seller, no suspension or cancellation of such Permit is threatened and there is no basis for believing that such Permit will not be renewable upon expiration.  Each such Permit is assignable by the Seller to the Buyer without the consent or approval of any party (other than consents or approvals listed in Section 2.15 of the Disclosure Schedule) and will continue in full force and effect immediately following the Closing.

2.16                           Certain Business Relationships With Affiliates.  Except as set forth in Section 2.16 of the Disclosure Schedule, no Affiliate of the Seller (a) owns any property or right, tangible or intangible, which is used in the Acquired Business or with the Acquired Assets, (b) has any claim or cause of action against the Seller with respect to the Acquired Business or Acquired Assets, or (c) owes any money to, or is owed any money by, the Seller with respect to the Acquired Business.  Section 2.16 of the Disclosure Schedule describes any transactions or relationships between the Seller and any Affiliate thereof which occurred or have existed since the beginning of the time period covered by the Financial Statements.

2.17                           Brokers’ Fees.  The Seller has no liability or obligation to pay any fees or commissions to any broker, finder or agent with respect to the transactions contemplated by this Agreement.

2.18                           Disclosure.  No representation or warranty by the Seller and the Primary Member contained in this Agreement, and no statement contained in the Disclosure Schedule or any other document, certificate or other instrument delivered or to be delivered by or on behalf of the Seller pursuant to this Agreement, contains or will contain any untrue statement of a material fact or omits or will omit to state any material fact necessary, in light of the circumstances under which it was or will be made, in order to make the statements herein or therein not misleading.

(a)                                  any breach of any representation or warranty of the Seller or the Primary Member contained in this Agreement, any Ancillary Agreement or any other agreement or instrument furnished by the Seller or the Primary Member to the Buyer pursuant to this Agreement;

(b)                                 any failure to perform any covenant or agreement of the Seller or the Primary Member contained in this Agreement, any Ancillary Agreement or any agreement or instrument furnished by the Seller or the Primary Member to the Buyer pursuant to this Agreement; or

(c)                                  any Retained Liabilities.

6.2                                 Indemnification by the Buyer.  The Buyer shall indemnify the Seller and the Primary Member in respect of, and hold them harmless against, any and all Damages incurred or suffered by the Seller or the Primary Member resulting from, relating to or constituting:

(a)                                  any breach of any representation or warranty of the Buyer contained in this Agreement, any Ancillary Agreement or any other agreement or instrument furnished by the Buyer to the Seller or the Primary Member pursuant to this Agreement;

(b)                                 any failure to perform any covenant or agreement of the Buyer contained in this Agreement, any Ancillary Agreement or any other agreement or instrument furnished by the Buyer to the Seller or the Primary Member pursuant to this Agreement;

14

(c)                                  any Assumed Liabilities; or

(d)                                 any Sales Taxes to which Seller may be obligated as a result of Buyer’s failure to pay such Sales Taxes pursuant to Section 5.3(b).

6.3                                 Indemnification Claims.

(a)                                  An Indemnified Party shall give written notification to the Indemnifying Party of the commencement of any Third Party Action.  Such notification shall be given within 20 days after receipt by the Indemnified Party of notice of such Third Party Action, and shall describe in reasonable detail (to the extent known by the Indemnified Party) the facts constituting the basis for such Third Party Action and the amount of the claimed damages; provided, however, that no delay or failure on the part of the Indemnified Party in so notifying the Indemnifying Party shall relieve the Indemnifying Party of any liability or obligation hereunder except to the extent of any damage or liability caused by or arising out of such failure.  Within 20 days after delivery of such notification, the Indemnifying Party may, upon written notice thereof to the Indemnified Party, assume control of the defense of such Third Party Action with counsel reasonably satisfactory to the Indemnified Party; provided that (i) the Indemnifying Party may only assume control of such defense if it acknowledges in writing to the Indemnified Party that any damages, fines, costs or other liabilities that may be assessed against the Indemnified Party in connection with such Third Party Action constitute Damages for which the Indemnified Party shall be indemnified pursuant to this Article VI and (ii) the Indemnifying Party may not assume control of the defense of Third Party Action involving criminal liability or in which equitable relief is sought against the Indemnified Party.  If the Indemnifying Party does not, or is not permitted under the terms hereof to, so assume control of the defense of a Third Party Action, the Indemnified Party shall control such defense.  The Non-controlling Party may participate in such defense at its own expense.  The Controlling Party shall keep the Non-controlling Party advised of the status of such Third Party Action and the defense thereof and shall consider in good faith recommendations made by the Non-controlling Party with respect thereto.  The Non-controlling Party shall furnish the Controlling Party with such information as it may have with respect to such Third Party Action (including copies of any summons, complaint or other pleading which may have been served on such party and any written claim, demand, invoice, billing or other document evidencing or asserting the same) and shall otherwise cooperate with and assist the Controlling Party in the defense of such Third Party Action.  The fees and expenses of counsel to the Indemnified Party with respect to a Third Party Action shall be considered Damages for purposes of this Agreement if (i) the Indemnified Party controls the defense of such Third Party Action pursuant to the terms of this Section 6.3(a) or (ii) the Indemnifying Party assumes control of such defense and the Indemnified Party reasonably concludes that the Indemnifying Party and the Indemnified Party have conflicting interests or different defenses available with respect to such Third Party Action.  The Indemnifying Party shall not agree to any settlement of, or the entry of any judgment arising from, any Third Party Action without the prior written consent of the Indemnified Party, which shall not be unreasonably withheld, conditioned or delayed; provided that the consent of the Indemnified Party shall not be required if the Indemnifying Party agrees in writing to pay any amounts payable pursuant to such settlement or judgment and such settlement or judgment includes a complete release of the Indemnified Party from further liability and has no other adverse effect on the Indemnified Party.  The Indemnified Party shall not agree to any settlement of, or the entry of any judgment arising from, any such Third Party Action without the prior written consent of the Indemnifying Party, which shall not be unreasonably withheld, conditioned or delayed.

(b)                                 In order to seek indemnification under this Article VI, an Indemnified Party shall deliver a Claim Notice to the Indemnifying Party.

15

(c)                                  Within 20 days after delivery of a Claim Notice, the Indemnifying Party shall deliver to the Indemnified Party a Response, in which the Indemnifying Party shall (i) agree that the Indemnified Party is entitled to receive all of the Claimed Amount (in which case the Response shall be accompanied by a payment by the Indemnifying Party to the Indemnified Party of the Claimed Amount, by check or by wire transfer), (ii) agree that the Indemnified Party is entitled to receive the Agreed Amount (in which case the Response shall be accompanied by a payment by the Indemnifying Party to the Indemnified Party of the Agreed Amount, by check or by wire transfer) or (iii) dispute that the Indemnified Party is entitled to receive any of the Claimed Amount.

(d)                                 During the 30-day period following the delivery of a Response that reflects a Dispute, the Indemnifying Party and the Indemnified Party shall use good faith efforts to resolve the Dispute.  If the Dispute is not resolved within such 30-day period, such Dispute shall be resolved in a state or federal court sitting in the Commonwealth of Massachusetts, in accordance with Section 9.12.

(e)                                  Notwithstanding the other provisions of this Section 6.3, if a third party asserts (other than by means of a lawsuit) that an Indemnified Party is liable to such third party for a monetary or other obligation which may constitute or result in Damages for which such Indemnified Party may be entitled to indemnification pursuant to this Article VI, and such Indemnified Party reasonably determines that it has a valid business reason to fulfill such obligation, then (i) such Indemnified Party shall be entitled to satisfy such obligation, with prior notice to and consent from the Indemnifying Party (provided that (A) such notice and/or consent shall not be required where commercially impracticable, (B) such consent shall not be unreasonably withheld, conditioned or delayed and (C) if such consent is not granted, then any additional damages incurred by Indemnified Party as a result of such failure to consent shall be considered Damages for purposes of this Agreement), (ii) such Indemnified Party may subsequently make a claim for indemnification in accordance with the provisions of this Article VI, and (iii) such Indemnified Party shall be reimbursed, in accordance with the provisions of this Article VI, for any such Damages for which it is entitled to indemnification pursuant to this Article VI (subject to the right of the Indemnifying Party to dispute the Indemnified Party’s entitlement to indemnification, or the amount for which it is entitled to indemnification, under the terms of this Article VI).

6.4                                 Survival of Representations and Warranties.  All representations and warranties that are covered by the indemnification agreements in Section 6.1(a) and Section 6.2(a) shall (a) survive the Closing and (b) shall expire on the date 24 months following the Closing Date, except that (i) the representations and warranties set forth in Sections 2.1, 2.2, 3.1 and 3.2 shall survive the Closing without limitation and (ii) the representations and warranties set forth in Section 2.7 shall survive until 30 days following expiration of all statutes of limitation applicable to the matters referred to therein.  If an Indemnified Party delivers to an Indemnifying Party, before expiration of a representation or warranty, either a Claim Notice based upon a breach of such representation or warranty, or an Expected Claim Notice based upon a breach of such representation or warranty, then the applicable representation or warranty shall survive until, but only for purposes of, the resolution of the matter covered by such notice.  If the legal proceeding or written claim with respect to which an Expected Claim Notice has been given is definitively withdrawn or resolved in favor of the Indemnified Party, the Indemnified Party shall promptly so notify the Indemnifying Party.  The rights to indemnification set forth in this Article VI shall not be affected by any investigation conducted by or on behalf of an Indemnified Party or any knowledge acquired (or capable of being acquired) by an Indemnified Party, whether before or after the date of this Agreement, with respect to the inaccuracy or noncompliance with any representation, warranty, covenant or obligation which is the subject of indemnification hereunder.

16

6.5                                 Limitations.

(a)          Notwithstanding anything to the contrary herein, the Seller and the Primary Member shall be liable for only (i) any single claim or related group of claims that exceeds $10,000  and (ii) that portion of the aggregate Damages under Section 6.1(a) for which they would otherwise be liable which exceeds $100,000; provided that the limitation set forth in this sentence shall not apply to a claim pursuant to Section 6.1(a) relating to a breach of the representations and warranties set forth in Sections 2.1, 2.3 or 2.7.  For purposes solely of this Article VI, all representations and warranties of the Seller in Article II (other than Sections 2.5 and 2.18) shall be construed as if the term “material” and any reference to “Seller Material Adverse Effect” (and variations thereof) were omitted from such representations and warranties.

(b)         Notwithstanding anything to the contrary herein, the Buyer shall be liable for only (i) any single claim or related group of claims that exceeds $10,000 and (ii) that portion of the aggregate Damages under Section 6.2(a) for which it would otherwise be liable which exceeds $100,000; provided that the limitation set forth in this sentence shall not apply to a claim pursuant to Section 6.2(a) relating to a breach of the representations and warranties set forth in Sections 3.1 or 3.2. For purposes solely of this Article VII, all representations and warranties of the Buyer in Article III shall be construed as if the term “material” were omitted from such representations and warranties.

(c)          The Buyer shall have the right to offset any Damages for which it is entitled to indemnification under this Agreement against any milestone consideration otherwise payable to the Seller under Section 1.4 of this Agreement.  However, the rights of the Buyer to offset such milestone consideration shall not be the exclusive means for the Buyer to enforce such rights.

(d)         Except with respect to claims based on fraud, after the Closing, the rights of the Indemnified Parties under this Article VI shall be the exclusive remedy of the Indemnified Parties with respect to claims resulting from or relating to any misrepresentation, breach of warranty or failure to perform any covenant or agreement contained in this Agreement by any Party hereto.

6.6                                 Treatment of Indemnity Payments.  Any payments made to an Indemnified Party pursuant to this Article VI shall be treated as an adjustment to the Purchase Price for tax purposes.

17

(a)                                  The Buyer may, by written notice to the Seller, (i) delay the filing or effectiveness of any Registration Statement or (ii) suspend any Registration Statement after effectiveness and require that the Seller immediately cease sales of shares pursuant to the Registration Statement, in the event that (A) the Buyer files a registration statement (other than a registration statement on Form S-8 or its successor form) with the SEC for a public offering of its securities or (B) the Buyer is engaged in any activity or transaction or preparations or negotiations for any activity or transaction that the Buyer desires to keep confidential for business reasons, if the Buyer determines in good faith that the public disclosure requirements imposed on the Buyer under the Securities Act in connection with such Registration Statement would require disclosure of such activity, transaction, preparations or negotiations.  Notwithstanding anything to the contrary herein, the Buyer shall not exercise its rights under this Section 7.2(a) to suspend sales of Milestone Shares for a period in excess of 90 days consecutively or 180 days in any 365-day period.

(b)                                 If the Buyer delays or suspends any Registration Statement or requires the Seller to cease sales of shares pursuant to paragraph (a) above, the Buyer shall, as promptly as practicable following the termination of the circumstance which entitled the Buyer to do so (or at the end of such 90-day period, whichever first occurs), take such actions as may be necessary to file or reinstate the effectiveness of such Registration Statement and/or give written notice to the Seller authorizing it to resume sales pursuant to such Registration Statement.  If as a result thereof the prospectus included in such Registration Statement has been amended to comply with the requirements of the Securities Act, the Buyer shall enclose such revised prospectus with the notice to the Seller given pursuant to this paragraph (b), and the Seller shall make no offers or sales of shares pursuant to such Registration Statement other than by means of such revised prospectus.

7.3                                 Registration Procedures.

(a)                                  In connection with the filing by the Buyer of any Registration Statement, the Buyer shall furnish to the Seller a copy of the prospectus, including a preliminary prospectus, in conformity with the requirements of the Securities Act.

(b)                                 The Buyer shall use its best efforts to register or qualify the applicable Milestone Shares covered by such Registration Statement under the securities laws of each state of the United States; provided, however, that the Buyer shall not be required in connection with this paragraph (b) to qualify as a foreign corporation or execute a general consent to service of process in any jurisdiction.

(c)                                  The Buyer shall, as expeditiously as possible, notify the Seller, promptly after it shall receive notice thereof, of the time when such Registration Statement has become effective or a supplement to any prospectus forming a part of such Registration Statement has been filed.

(d)                                 The Buyer shall, as expeditiously as possible, cause all such Milestone Shares to be listed on each securities exchange or automated quotation system on which similar securities issued by the Buyer are then listed.

(e)                                  The Buyer shall promptly provide a transfer agent, registrar and CUSIP number for all such Milestone Shares not later than the effective date of such registration statement.

(f)                                    If the Buyer has delivered preliminary or final prospectuses to the Seller and after having done so the prospectus is amended or supplemented to comply with the requirements of the Securities Act, the

18

Buyer shall promptly notify the Seller and, if requested by the Buyer, the Seller shall immediately cease making offers or sales of shares under such Registration Statement and return all prospectuses to the Buyer.  The Buyer shall promptly provide the Seller with revised or supplemented prospectuses and, following receipt of the revised or supplemented prospectuses, the Seller shall be free to resume making offers and sales under such Registration Statement.

(g)                                 The Buyer shall, as expeditiously as possible following the effectiveness of such Registration Statement, notify the Seller of any request by the SEC for the amending or supplementing of such Registration Statement or prospectus.

7.4                                 Requirements of the Seller.  The Buyer shall not be required to include any Milestone Shares in any Registration Statement unless:

(a)                                  the Seller furnishes to the Buyer in writing such information regarding the Seller and the proposed sale of Milestone Shares by the Seller as the Buyer may reasonably request in writing in connection with such Registration Statement or as shall be required in connection therewith by the SEC or any state securities law authorities;

(ii)                                  to report to the Buyer sales made pursuant to such Registration Statement.

7.5                                 Indemnification.  The Buyer agrees to indemnify and hold harmless the Seller against any losses, claims, damages, expenses or liabilities to which the Seller may become subject by reason of (i) any untrue statement of a material fact contained in any Registration Statement, any preliminary prospectus or final prospectus contained in the Registration Statement, or any amendment or supplement to such Registration Statement, (ii) or any omission to state therein a fact required to be stated therein or necessary to make the statements therein not misleading, or (iii) any violation or alleged violation by the Buyer of the Securities Act, the Exchange Act, any state securities law or any rule or regulation promulgated under the Securities Act, the Exchange Act or any state securities law in connection with the Registration Statement or the offering contemplated thereby; except insofar as such losses, claims, damages, expenses or liabilities arise out of or are based upon information furnished to the Buyer by or on behalf of the Seller for use in such Registration Statement.  The Buyer shall have the right to assume the defense and settlement of any claim or suit for which the Buyer may be responsible for indemnification under this Section 7.5.

19
