                          (a)        Purchase and Sale. Upon the terms and subject to the conditions of this Agreement, on the Closing Date, Seller shall sell, transfer, assign and convey to Purchaser, and Purchaser shall purchase, acquire and accept from Seller, free and clear of all Adverse Claims (other than Permitted Adverse Claims or Adverse Claims arising through Purchaser), all of Seller’s right, title and interest in and to the Purchased Receivables.

                          (b)        Purchase Price. The purchase price for the Purchased Receivables shall be $6,000,000 (the “Purchase Price”), less Purchaser’s out-of-pocket fees, costs and expenses (including legal fees) and other amounts (the “Purchaser’s Expenses”), payable by Purchaser to Seller on the Closing Date as required by Section 8.3 hereof.

            Section 2.2        No Purchase or Sale of Excluded Assets. Except for the Purchased Receivables and as otherwise set forth in this Agreement, Seller shall retain all of its right, title and interest in and to the Product, and all rights to the Product and rights under the Product Agreement and any Additional License Agreements are excluded from the sale, transfer, assignment and conveyance to Purchaser under this Agreement.

6

            Section 2.3        No Obligations Transferred. Notwithstanding anything to the contrary contained in this Agreement, (a) the sale, transfer, assignment and conveyance to Purchaser of the Purchased Receivables pursuant to this Agreement shall not in any way subject Purchaser to, or transfer, affect or modify, any obligation or liability of Seller under any Product Agreement and (b) Purchaser expressly does not assume or agree to become responsible for any obligation or liability of Seller under any Product Agreement or otherwise.

            Section 2.4        Sale. It is the intention of the parties hereto that the sale, transfer, assignment and conveyance contemplated by this Agreement shall constitute a sale of the Purchased Receivables from Seller to Purchaser and not a financing transaction, borrowing or loan; and accordingly, Seller and Purchaser will treat the sale, transfer, assignment and conveyance of the Purchased Receivables as sales of “accounts” for accounting purposes, and Seller hereby authorizes Purchaser or its designee, from and after the Closing Date, to execute, record and file such financing statements (and continuation statements with respect to such financing statements when applicable) naming Seller as the seller/debtor and Purchaser as the purchaser/secured party of the Purchased Receivables as may be necessary to perfect such sale in accordance with the UCC and the Code, as applicable. If, notwithstanding the intent of the parties hereto in this regard, the sale, transfer, assignment and conveyance contemplated hereby is held not to be a sale, this Agreement shall constitute a security agreement and Seller does hereby grant to Purchaser a security interest and hypothec in and to the Purchased Receivables, whether now owned or hereafter acquired or arising, and wherever located, and any proceeds, to secure payment to Purchaser of amounts equal to the Purchased Receivables as they are paid under the Product Agreements, and Seller does hereby authorize Purchaser to file such financing statements (and continuation statements with respect to such financing statements when applicable) as may be necessary to perfect its security interest. Seller waives, to the maximum extent permitted by law, any right to contest or otherwise assert that this Agreement is other than a true, complete, absolute and irrevocable sale by Seller to Purchaser of the Purchased Receivables under applicable Law, which waiver shall be enforceable, to the maximum extent permitted by law, against Seller in any bankruptcy or insolvency proceeding relating to Seller. The sale, transfer, assignment and conveyance of the Purchased Receivables shall be reflected on Seller’s financial statements and other records as a sale of assets to Purchaser. Seller agrees that in any consolidated financial statements of Seller it shall indicate that the Purchased Receivables are the assets of Purchaser.

            Section 2.5        Nonassignable Assets. Nothing in this Agreement nor the consummation of the transactions contemplated hereby shall be construed as an attempt or agreement to assign any asset included in the Purchased Receivables, including any Contract, approval, authorization or other right, which by its terms or by Law is nonassignable without the consent of a third party or is cancelable by a third party in the event of an assignment (“Nonassignable Assets”) unless and until such consent shall have been obtained or to the extent any such assignment restriction is removed or expires by its term. Seller shall use its commercially reasonable efforts to cooperate with Purchaser in endeavoring to obtain such consents promptly. In the event consents to the assignment thereof cannot be obtained, such Nonassignable Assets shall be held by Seller in trust for Purchaser and the covenants and obligations thereunder shall be performed by Seller in Purchaser’s name and all benefits and obligations existing thereunder shall be for Purchaser’s account. Seller shall take such actions as Purchaser may reasonably request so as to provide Purchaser with the benefits of the Nonassignable Assets and to effect collection of money or other consideration that becomes due and payable under the Nonassignable Assets, and Seller shall promptly pay over to Purchases all money or other consideration received by it in respect of all Nonassignable Assets.

7

            Section 2.6        Power of Attorney. As of and from the Closing Date, Seller on behalf of itself and its Affiliates hereby irrevocably constitutes and appoints Purchaser, to the extent permitted by applicable Law and the terms of the Nonassignable Assets, with full power of substitution, as Seller’s true and lawful attorney-in-fact with full irrevocable power and authority in the place and stead of Seller and in the name of Seller or in its own name, from time to time in Purchaser’s discretion, to take any and all appropriate action and to execute and deliver any and all documents and instruments which may be necessary or desirable to accomplish the purposes of this Agreement and the Bill of Sale and, without limiting the generality of the foregoing, to the extent that Seller has the right under applicable Law and any applicable Contract, Seller hereby grants to Purchaser the power and right, on behalf of Seller, to the extent Seller has the legal power or right to do such act for its own benefit without notice to or assent by Seller, and at any time, to do the following: (a) pay or discharge any taxes, liens, security interests, or other encumbrances or other Adverse Claims levied or placed on or threatened against the Purchased Receivables (other than Adverse Claims arising through Purchaser); (b) communicate in its own name with any party to any Contract with regard to the assignment of the right, title and interest of Seller in and under the Purchased Receivables and other matters relating thereto; (c) execute, in connection with the transfer of title, any endorsements, assignments or other instruments of conveyance or transfer with respect to the Purchased Receivables, (d) to perform all the obligations and receive all the benefits of Seller under the Nonassignable Assets, and (e) defend, exercise or enforce any of Seller’s rights under the Product Agreements in any manner reasonably necessary or advisable to protect Purchaser’s rights under this Agreement and appoint Purchaser their attorneys-in-fact to act in their name on their behalf.

If reasonably requested by Purchaser, Seller shall execute a stand-alone power of attorney consistent with the terms of this Section 2.6 to enable Purchaser to present such power of attorney to other parties without disclosing this Agreement.

            Section 2.7        No Guarantee of Purchased Receivables. Seller makes no guarantee to Purchaser that Net Sales of the Product will equal any minimum amount or that Royalty Payments or Purchased Receivables will equal any minimum amount.

                          (a)        Administration.

ARTICLE VII

INDEMNIFICATION

            Section 7.1        Obligation of Parties to Indemnify.

                          (a)        Indemnification by Seller. Subject to the limitations set forth in this Article VII, Seller shall indemnify, defend and hold harmless, Purchaser, its Affiliates and their respective employees, officers, directors and agents (each, a “Purchaser Indemnified Party”) against any and all losses, liabilities, expenses (including reasonable attorneys’ fees and expenses in connection with any third party action, suit or proceeding) and damages (collectively, “Losses”) incurred by any of them, to the extent arising or resulting from any of the following:

                          (i)        any breach of any representation or warranty made by Seller in this Agreement or any other Transaction Document delivered to Purchaser in connection herewith;

                          (ii)       any breach of any covenant of Seller contained in this Agreement or any other Transaction Document delivered to Purchaser in connection herewith; and

                          (iii)      any obligations of Seller in accordance with Section 2.3 hereof.

21

                          (b)        Indemnification by Purchaser. Subject to the limitations set forth in this Article VII, Purchaser shall indemnify Seller, its Affiliates and their respective employees, officers, directors and agents (each a “Seller Indemnified Party”) against any and all Losses incurred by any of them, to the extent arising or resulting from any of the following:

                          (i)        any breach of any representation or warranty made by Purchaser in this Agreement or any other Transaction Document delivered to Seller in connection herewith; and

                          (ii)       any breach of any covenant of Purchaser contained in this Agreement or any other Transaction Document delivered to Seller in connection herewith.

            Section 7.2        Procedures Relating to Indemnification for Third Party Claims.

                          (a)        Notice of Third Party Claim. In order for a party (an “Indemnified Party”) to be entitled to any indemnification under this Article VII in respect of Losses arising out of or involving a claim or demand made by any Person other than Purchaser or Seller against a Purchaser Indemnified Party or a Seller Indemnified Party, as applicable (a “Third Party Claim”), the Indemnified Party must notify the party from whom indemnification is sought under this Article VII (the “Indemnifying Party”) promptly in writing (including in such notice a brief description of the Third Party Claim, including damages sought or estimated, to the extent actually known or reasonably capable of estimation by the Indemnified Party); provided, however, that the failure to promptly provide such notice shall not affect the indemnification provided under this Article VII except to the extent that the Indemnifying Party has been actually prejudiced as a result of such failure. Thereafter, the Indemnified Party shall deliver to the Indemnifying Party, promptly after the Indemnified Party’s receipt thereof, copies of all documents (including court papers) received by the Indemnified Party relating to the Third Party Claim.

                          (b)        Defense of Third Party Claims. The Indemnifying Party shall be entitled to participate in the defense of the Third Party Claim and, if it so chooses, to assume the defense thereof, at its own expense, with counsel selected by the Indemnifying Party (so long as such counsel is not reasonably objected to by the Indemnified Party) if: (i) the Indemnifying Party makes reasonably adequate provision to satisfy the Indemnified Party of the Indemnifying Party’s ability to defend, satisfy and discharge such Third-Party Claim; (ii) no material defense exists for the Indemnified Party which is not available to the Indemnifying Party; and (iii) if the named parties to such Third Party Claim (including impleaded parties) include both the Indemnifying Party and the Indemnified Party, representation of both parties by the same counsel would not be appropriate due to actual material differing interests between them (as determined by the Indemnified Party in its reasonable discretion) (collectively, the “Defense Conditions”). If the Indemnifying Party elects to assume the defense of any Third Party Claim, the Indemnifying Party shall not be liable to the Indemnified Party for legal expenses subsequently incurred by the Indemnified Party in connection with the defense thereof; provided, however, that if any of the Defense Conditions cease to be satisfied for any reason, the Indemnified Party may assume its own defense, and the Indemnifying Party will be liable for all reasonable costs or expenses paid or incurred in connection therewith, and the Indemnified Party shall have the right to compromise or settle such Third Party Claim with the consent of the Indemnifying Party (which consent shall not be unreasonably withheld or delayed) and, if settled with such consent, or if there is a final judgment against the Indemnified Party, the Indemnifying Party agrees to indemnify the Indemnified Party from and against any loss or liability by reason of such settlement or judgment. In the event the Indemnifying Party has assumed control of the defense of the Third Party Claim, the Indemnifying Party shall permit the Indemnified Party to participate in, but not control, the defense of any such action or suit through counsel chosen by the Indemnified Party; provided that such counsel is not reasonably objected to by the Indemnifying Party and the fees and expenses of such counsel shall be borne by the Indemnified Party. The Indemnifying Party shall be liable for the fees and expenses of counsel employed by the Indemnified Party in the defense of a Third Party Claim for any period during which the Indemnifying Party has not assumed the defense thereof (other than during the period prior to the time the Indemnified Party shall have notified the Indemnifying Party of such Third Party Claim).

22

                          (c)        Cooperation. The parties hereto shall cooperate in the defense or prosecution of any Third Party Claim, with such cooperation to include (i) the retention of and the provision to the Indemnifying Party of records and information that are reasonably relevant to such Third Party Claim and (ii) the making available of employees on a mutually convenient basis for providing additional information and explanation of any material provided hereunder. If the Indemnifying Party shall have assumed the defense of a Third Party Claim, the Indemnified Party shall agree to any settlement, compromise or discharge of such Third Party Claim that the Indemnifying Party may recommend and that by its terms obligates the Indemnifying Party to pay the full amount of the liability (if any) in connection with such Third Party Claim and which (i) does not include a statement as to or admission of, fault, culpability or a failure to act by or on behalf of any such Indemnified Party, (ii) includes an unconditional release of such Indemnified Party from all liability on claims that are the subject matter of such Third Party Claim and (iii) does not provide for injunctive relief or other relief relating to such Indemnified Party other than monetary damages.

            Section 7.3        Procedures Relating to Indemnification for Other Claims. In order for an Indemnified Party to be entitled to any indemnification under this Article VII in respect of Losses that do not arise out of or involve a Third Party Claim, the Indemnified Party must notify the Indemnifying Party promptly in writing (including in such notice a brief description of the claim for indemnification and the Loss, including damages sought or estimated, to the extent actually known or reasonably capable of estimation by the Indemnified Party); provided, however, that the failure to promptly provide such notice shall not affect the indemnification provided under this Article VII except to the extent that the Indemnifying Party has been actually prejudiced as a result of such failure.

            Section 7.4        Exclusive Remedy. Other than for claims for equitable relief, including the seeking of specific performance in accordance with Section 8.12, the parties hereto acknowledge and agree that, from and after the Closing Date, this Article VII (including Section 7.4) shall provide such parties’ sole and exclusive remedy with respect to any matter or claim arising out of, relating to, or in connection with, this Agreement and the transactions contemplated hereby, except that any such claim or matter based upon common law fraud shall not be subject to or limited by this Article VII and each of Purchaser and Seller accordingly preserves all remedies available with respect to any such claim or matter based thereon under applicable Law.

23

            Section 7.5        Survival. Subject to the limitations and other provisions of this Agreement, the representations and warranties contained herein shall survive the Closing and shall remain in full force and effect until the date that is twenty months from the Closing Date. None of the covenants or other agreements contained in this Agreement shall survive the Closing Date other than those which by their terms contemplate performance after the Closing Date, and each such surviving covenant and agreement shall survive the Closing until fully performed, or if earlier, the date upon which all of the Product Agreements have been terminated. Notwithstanding the foregoing, any claims asserted in good faith with reasonable specificity (to the extent known at such time) and in writing by notice from the non-breaching party to the breaching party prior to the expiration date of the applicable survival period shall not thereafter be barred by the expiration of such survival period and such claims shall survive until finally resolved.

            Section 7.6        Limitations on Damages.

                          (a)        Seller shall not be liable to any Purchaser Indemnified Party until the aggregate amount of all Losses suffered by Purchaser Indemnified Parties exceeds 1% of the Purchase Price (the “Threshold”) in which event the Seller shall be required to pay or be liable for all Losses to the first dollar, regardless of the Threshold; provided, however, that the Threshold shall not apply to Seller’s obligations hereunder to transfer the Purchased Receivables to Purchaser; provided, further, that nothing in this Section 7.6(a) shall be construed as a prohibition against Purchaser’s right to seek specific performance under Section 8.12.

                          (b)        The aggregate amount of all Losses for which Seller shall be liable pursuant to this Agreement shall not exceed an amount equal to the Purchase Price plus an annual rate of return of 12% (compounded monthly), less the amount of all payments received by Purchaser hereunder, including indemnification payments, and any Royalty Payments actually received by Purchaser (as so calculated, the “Cap”); provided, however, that the Cap shall not apply to Seller’s obligations hereunder to transfer the Purchased Receivables to Purchaser.

                          (c)        Payments by Seller in respect of any Loss shall be limited to the amount of any liability or damage that remains after deducting therefrom any insurance proceeds and any indemnity, contribution or other similar payment received or reasonably expected to be received by the Purchaser Indemnified Party in respect of any such claim. The Purchaser Indemnified Party shall use its commercially reasonable efforts to recover under insurance policies or indemnity, contribution or other similar agreements for any Losses prior to seeking indemnification under this Agreement.

                          (d)        Notwithstanding anything contained in this Agreement to the contrary, “material” and “Seller Material Adverse Effect” or similar materiality type qualifications contained in the representations and warranties set forth in this Agreement shall be ignored and not given any effect for purposes of calculating the amount of any Losses, but not the determination of whether there has been a breach, which determination shall give full effect to all “material”, “Seller Material Adverse Effect” and similar materiality type qualifications.

24

                          (e)        All indemnification payments made under this Agreement shall be treated by the parties as an adjustment to the Purchase Price for Tax purposes, unless otherwise required by Law.

                          (f)        Notwithstanding anything to the contrary in this Agreement, whether based upon a claim or action of contract, warranty, negligence or tort, or otherwise arising out of this Agreement, in no event shall either party hereto be liable for any consequential, exemplary or punitive damages unless such damages are payable to a third party in connection with a Third Party Claim or are based upon common law fraud.

                          (a)        This Agreement may be amended, modified or supplemented, or any provision hereof waived, only in a writing signed by Seller and Purchaser.

                          (b)        No failure or delay on the part of either party hereto in exercising any right, power or remedy hereunder shall operate as a waiver thereof, nor shall any single or partial exercise of any such right, power or remedy preclude any other or further exercise thereof or the exercise of any other right, power or remedy. No course of dealing between the parties hereto shall be effective to amend, modify, supplement or waive any provision of this Agreement.

26

This Agreement, including the Exhibits and Schedules attached to this Agreement, sets forth the entire agreement and understanding between the parties hereto as to the subject matter hereof. All express or implied agreements, arrangements, representations and understandings as to the subject matter hereof, whether oral or written, heretofore made are superseded by this Agreement.

            Section 8.10      Governing Law. THIS AGREEMENT SHALL BE GOVERNED BY, AND SHALL BE CONSTRUED AND ENFORCED IN ACCORDANCE WITH, THE LAWS OF THE STATE OF NEW YORK WITHOUT REGARD TO CONFLICT OF LAWS PRINCIPLES THEREOF (OTHER THAN SECTIONS 5-1401 AND 5-1402 OF THE NEW YORK GENERAL OBLIGATIONS LAW).

            Section 8.11      Jurisdiction; Venue; Service Of Process; Waiver of Jury Trial. Each party hereto irrevocably submits to the exclusive jurisdiction of (a) the United States District Court for the Southern District of New York, and (b) the Supreme Court of the State of New York, New York County, for the purposes of any suit, action or other proceeding arising out of this Agreement or any transaction contemplated hereby. Each party hereto agrees to commence any action, suit or other proceeding relating hereto in the courts of United States District Court for the Southern District of New York or, if such suit, action or other proceeding may not be brought in such court for jurisdictional reasons, in the Supreme Court of the State of New York located in New York County. Each party hereto irrevocably and unconditionally waives any objection to the laying of venue of any action, suit or other proceeding arising out of this Agreement and the transactions contemplated hereby in (a) the United States District Court for the Southern District of New York, or (b) the Supreme Court of the State of New York, New York County, and hereby further irrevocably and unconditionally waives, and shall not assert by way of motion, defense, or otherwise, in any such suit, action or proceeding, any claim that it is not subject personally to the jurisdiction of the above-named courts, that its property is exempt or immune from attachment or execution, that the suit, action or proceeding is brought in an inconvenient forum, that the venue of the suit, action or proceeding is improper, or that this Agreement and the transactions contemplated hereby and thereby may not be enforced in or by any of the above-named courts. EACH OF SELLER AND PURCHASER HEREBY WAIVES, TO THE FULLEST EXTENT PERMITTED BY LAW, THE RIGHT TO TRIAL BY JURY IN ANY ACTION, PROCEEDING OR COUNTERCLAIM FILED BY EITHER PARTY, WHETHER IN CONTRACT, TORT OR OTHERWISE, RELATING DIRECTLY OR INDIRECTLY TO THIS AGREEMENT AND THE TRANSACTIONS CONTEMPLATED HEREIN.

27

            Section 8.12      Equitable Remedies. The parties agree that irreparable damage for which monetary damages, even if available, would not be an adequate remedy, would occur in the event that the parties hereto do not perform their respective obligations under the provisions of this Agreement in accordance with their specific terms or otherwise breach such provisions. It is accordingly agreed that the parties shall be entitled to seek an injunction or injunctions, specific performance and other equitable relief to prevent breaches of this Agreement and to enforce specifically the terms and provisions of this Agreement, including, without limitation, Seller’s obligation to enforce, and perform its obligations under, the Product Agreements. Each of the parties agrees that it will not oppose the granting of an injunction, specific performance and other equitable relief when expressly available pursuant to the terms of this Agreement on the basis that the other party has an adequate remedy at law or an award of specific performance is not an appropriate remedy for any reason at law or equity.

            Section 8.13      Severability. If any term or provision of this Agreement is held to be invalid, illegal or unenforceable by a court or other Governmental Entity of competent jurisdiction, such invalidity, illegality or unenforceability shall not affect any other term or provision of this Agreement, which shall remain in full force and effect, and the parties hereto shall replace such term or provision with a new term or provision permitted by applicable Law and having an economic effect as close as possible to the invalid, illegal or unenforceable term or provision. The holding of a term or provision to be invalid, illegal or unenforceable in a jurisdiction shall not have any effect on the application of the term or provision in any other jurisdiction.

            Section 8.14      Counterparts. This Agreement may be executed in any number of counterparts and by the parties hereto in separate counterparts, each of which when so executed shall be deemed to be an original and all of which taken together shall constitute one and the same agreement.
