Rhythm shall pay such invoice as soon as reasonably practicable so as to assure that Manufacturer has received cleared funds prior to making the payment of such VAT. Upon determination of the actual amount of such VAT due and payable, Manufacturer shall promptly (i) pay such amount to the applicable taxing authority; (ii) provide documentation reasonably acceptable to Rhythm with respect to both the actual amount of such VAT and Manufacturer’s payment thereof; and (iii) refund to Rhythm the excess amount (if any) previously paid by Rhythm pursuant to the first two sentences of this Section 8.2(a) over such actual amount of such VAT paid by Manufacturer, or, if such actual amount of such VAT paid by Manufacturer exceeds such amounts previously paid by Rhythm, invoice Rhythm for the amount of such deficiency (any such invoice shall be due thirty (30) days after receipt of such invoice and reasonable supporting documentation by Rhythm).

8.3                               Payments. Rhythm will make all payments pursuant to this Agreement by check or wire transfer to a bank account designated in writing by Manufacturer. All payments under this Agreement will be made in Euros.

8.4                               Financial Records. Manufacturer will keep accurate records of all Services performed and invoice calculations, and, upon the request of Rhythm, will permit Rhythm or its duly authorized agents to examine such records during normal business hours for the purpose of verifying the correctness of all such calculations.

8.5                               Taxes. Duty, sales, use or excise taxes imposed by any governmental entity that apply to the provision of Services will be borne by Rhythm (other than taxes based upon the income of Manufacturer).

9.                                      Intellectual Property Rights.

9.1                               Rhythm Technology. All rights to and interests in Rhythm Technology will remain solely in Rhythm and no right or interest therein is transferred or granted to Manufacturer under this Agreement. Manufacturer acknowledges and agrees that it does not acquire a license or any

11

other right to Rhythm Technology except for the limited purpose of carrying out its duties and obligations under this Agreement and that such limited, non-exclusive, license will expire upon the completion of such duties and obligations or the termination or expiration of this Agreement, whichever is the first to occur.

9.2                               Manufacturer Technology. All rights to and interests in Manufacturer Technology will remain solely in Manufacturer and, except as otherwise set forth in this Agreement, no right or interest therein is transferred or granted to Rhythm under this Agreement. Manufacturer hereby grants to Rhythm a non-exclusive, perpetual, irrevocable, royalty-free, transferable and sublicensable license to Rhythm and its Affiliates to use and modify Manufacturer Technology to develop, Manufacture, have Manufactured, distribute, offer for sale, sell, and otherwise dispose of Product.

9.3                               Improvements. Manufacturer agrees (a) to promptly disclose to Rhythm all patentable Improvements, and (b) that all Improvements will be the sole and exclusive property of Rhythm, and are hereby assigned to Rhythm (or its designee), and (c) that any such assignment to Rhythm (or its designee) shall be made without additional compensation to Manufacturer. Manufacturer will take such steps as Rhythm may reasonably request (at Rhythm’s expense) to vest in Rhythm (or its designee) ownership of the Improvements.

9.4                               Patent Filings. Rhythm will have the exclusive right and option, but not the obligation, to prepare, file, prosecute, maintain and defend, at its sole expense, any patents that claim or cover the Improvements.

9.5                               Technology Transfer. If Rhythm elects to Manufacture Product, or to have Product Manufactured by a third party, then Manufacturer will provide to Rhythm or its designee, all Manufacturing information, including, without limitation, documentation, technical assistance, materials and cooperation by appropriate employees of Manufacturer as Rhythm or its designee may reasonably require in order to Manufacture Product. Rhythm will compensate Manufacturer for such assistance at the hourly-rate(s) set forth in the applicable Work Order, or such other reasonable rate(s) as the parties may agree in writing.

10.                               Confidentiality.

10.1                        Confidential Information. During the Term and continuing thereafter, each party will keep confidential and not disclose to others or use for any purpose other than as necessary to fulfill its obligations or in the reasonable exercise of rights granted to it under this Agreement, all “Confidential Information”. As used in this Agreement, “Confidential Information” means any scientific, technical, trade or business information which is given by one party or its Affiliates or their respective employees or representatives to the other, either under a Confidentiality Agreement entered into by the parties in anticipation of this Agreement or under this Agreement, and which is treated by the disclosing party as confidential or proprietary or a trade secret, or is which is developed by one party for the other under the terms of this Agreement. Confidential Information of Manufacturer includes, but is not limited to, Manufacturer Technology. Confidential Information of Rhythm includes, but is not limited to, Rhythm Technology and Improvements. The restrictions of this Section 10.1 will not apply to any portion of the Confidential Information which (a) is known to the recipient at the time of disclosure and is not subject to another confidentiality obligation to the discloser or its Affiliates, as reasonably documented by recipient’s written records; (b) later becomes public knowledge through no fault of the recipient; (c) is received from a third party having the lawful right to disclose the information; or (d) is independently developed by or on behalf of recipient without use of or reliance upon discloser’s Confidential Information.

12

Information will not be deemed to be part of the “public domain” by reason solely that it is known to only a few of those people to whom it might be of commercial interest, and a combination of two (2) or more portions of the Confidential Information shall not be deemed to be generally available to the public by reason solely of each separate portion being so available.

10.2                        Permitted Disclosure. A party may disclose Confidential Information of the other party to (a) its Affiliates, and to its and their directors, employees, consultants, and agents in each case who have a specific need to know such Confidential Information and who are bound by a like obligation of confidentiality and restriction on use and (b) the extent such disclosure is required to comply with Applicable Law, the rules of any stock exchange or listing entity, or to defend or prosecute litigation; provided, however, that the recipient provides prior written notice of such disclosure to the discloser and takes reasonable and lawful actions to avoid or minimize the degree of such disclosure, including upon the discloser’s request, seeking confidential treatment of such Confidential Information. Moreover, Rhythm may disclose Confidential Information of Manufacturer relating to the Development and/or Manufacture of Product to entities with whom Rhythm has (or may have) a marketing and/or development collaboration or to bona fide actual or prospective underwriters, investors, lenders or other financing sources or to potential acquirors of the business to which this Agreement relates, and who in each case have a specific need to know such Confidential Information and who are bound by a like obligation of confidentiality and restrictions on use,

10.3                        Return of Confidential Information. This Agreement does not constitute the conveyance of ownership with respect to or a license to any Confidential Information, except as otherwise provided in this Agreement. Upon the expiration or termination of this Agreement for any reason, each party agrees, except as otherwise provided in this Agreement, to return to the other party all documentation or other tangible evidence or embodiment of Confidential Information belonging to the other party and not to use such Confidential Information, unless otherwise agreed. Notwithstanding the foregoing, one archival copy may be maintained by the recipient and kept confidential and segregated from the recipient’s regular files.

10.4                        Public Statements. Manufacturer will not make any public statements or releases concerning this Agreement or the transactions contemplated by this Agreement, or use Rhythm’s name in any form of advertising, promotion or publicity, without obtaining the prior written consent of Rhythm.

11.2                        Rhythm Representations and Warranties. Rhythm represents and warrants to Manufacturer that:

(a) it has the full power and right to enter into this Agreement and that there are no outstanding agreements, assignments, licenses, encumbrances or rights held by other parties, private or public, that are inconsistent with the provisions of this Agreement; and

(b) the execution and delivery of this Agreement by Rhythm has been authorized by all requisite corporate action and this Agreement is and will remain a valid and binding obligation of Rhythm, enforceable in accordance with its terms, subject to laws of general application relating to bankruptcy, insolvency and the relief of debtors.

14

EXCEPT AS EXPRESSLY SET FORTH IN THIS AGREEMENT, NEITHER PARTY MAKES ANY REPRESENTATIONS OR EXTENDS ANY WARRANTIES OF ANY KIND, EITHER EXPRESS OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, OR NON-INFRINGEMENT.

12.                               Indemnification.

12.1                        Indemnification by Manufacturer. Manufacturer agrees to indemnify, defend and hold harmless Rhythm, its Affiliates and its and their respective officers, directors, employees, subcontractors, and agents (collectively, the “Rhythm Indemnitees”) against any and all losses, damages, liabilities or expenses (including reasonable attorneys fees and other costs of defense) (collectively, “Losses”) in connection with any and all actions, suits, claims or demands that may be brought or instituted against any Rhythm Indemnitee by any third party alleging the infringement of third-party rights by Rhythm’s use, in supplying the Products, of any process, method, Specification or information process or method, other than one supplied to Manufacturer by Rhythm.

12.2                        Indemnification by Rhythm. Rhythm agrees to indemnify, defend and hold harmless Manufacturer, its Affiliates and its and their respective officers, directors, employees, subcontractors, and agents (collectively, the “Manufacturer Indemnitees”) against any and all Losses in connection with any and all actions, suits, claims or demands that may be brought or instituted against any Manufacturer Indemnitee by any third party to the extent they arise out of or relate to the use of the Product (except to the extent that such Losses are within the scope of the indemnification obligation of Manufacturer under Section 12.1),

12.3                        Indemnification Procedures. Each party shall notify the other party within thirty (30) days of receipt of any claims made for which the other party might be liable under Section 12.1 or 12.2, as the case may be. Subject to Section 12.4, the indemnifying party will have the sole right to defend, negotiate, and settle such claims. The indemnified party will be entitled to participate in the defense of such matter and to employ counsel at its expense to assist in such defense; provided, however, that the indemnifying party will have final decision-making authority regarding all aspects of the defense of any claim. The party seeking indemnification will provide the indemnifying party with such information and assistance as the indemnifying party may reasonably request, at the expense of the indemnifying party. The parties understand that no insurance deductible will be credited against losses for which a party is responsible under this Section 12.

12.4                        Settlement. Neither party will be responsible or bound by any settlement of any claim or suit made without its prior written consent; provided, however, that the indemnified party will not unreasonably withhold or delay such consent. If a settlement contains an absolute waiver of liability for the indemnified party, and each party has acted in compliance with the requirements of Section 12.3, then the indemnified party’s consent will be deemed given. Notwithstanding the foregoing, Manufacturer will not agree to settle any claim on such terms or conditions as would impair Rhythm’s ability or right to Manufacture, market, sell or otherwise use Product, or as would impair Manufacturer’s ability, right or obligation to perform its obligations under this Agreement.

15

12.5                        Limitation of Liability.

(a)                                 NEITHER PARTY WILL BE LIABLE TO THE OTHER UNDER ANY LEGAL THEORY (WHETHER TORT, CONTRACT OR OTHERWISE) FOR SPECIAL, INDIRECT, INCIDENTAL, CONSEQUENTIAL OR PUNITIVE DAMAGES ARISING OUT OF OR RELATED TO THIS AGREEMENT OR THE EXERCISE OF ITS RIGHTS HEREUNDER, INCLUDING LOST PROFITS ARISING FROM OR RELATING TO ANY BREACH OF THIS AGREEMENT, HOWEVER CAUSED, EVEN IF THE PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES, EXCEPT AS A RESULT OF A BREACH OF THE CONFIDENTIALITY AND NON-USE OBLIGATIONS IN SECTION 10. NOTHING IN THIS SECTION 12.5 IS INTENDED TO LIMIT OR RESTRICT THE INDEMNIFICATION RIGHTS OR OBLIGATIONS OF EITHER PARTY.

The term of this Agreement may be extended by Rhythm continuously for additional two (2) year periods upon written notice to Manufacturer at least thirty (30) days prior to the expiration of the then current term.

14.2                        Termination by Rhythm. Rhythm will have the right, in its sole discretion, to terminate this Agreement or any Work Order (a) upon sixty (60) days prior written notice to Manufacturer, or (b) immediately upon written notice if (i) in Rhythm’s reasonable judgment, Manufacturer is or will be unable to perform the Services in accordance with the agreed upon timeframe and/or budget set forth in the applicable Work Order, or (ii) Manufacturer fails to obtain or maintain any material governmental licenses or approvals required in connection with the Services.

In the case of a force majeure event relating solely to a pending Work Order, the right to terminate will be limited to such Work Order.

17

14.4                        Effect of Termination. Manufacturer will, upon receipt of a termination notice from Rhythm, promptly cease performance of the applicable Services and will take all reasonable steps to mitigate the out-of-pocket expenses incurred in connection therewith. In particular, Manufacturer will use all commercially reasonable efforts to:

(a)                                 immediately cancel, to the greatest extent possible, any third party obligations;

(b)                                 promptly inform Rhythm of any irrevocable commitments made in connection with any pending Work Order(s) prior to termination;

(c)                                  to the greatest extent possible promptly return to the vendor for a refund all unused, unopened materials in Manufacturer’s possession that are related to any pending Work Order; provided, that Rhythm will have the option, but not the obligation, to take possession of any such materials;

(d)                                 promptly inform Rhythm of the cost of any remaining unused, unreturnable materials ordered pursuant to any pending Work Order(s) according to minimum order quantity of Manufacturer’s suppliers, and either deliver such materials to Rhythm (or its designee) or properly dispose of them, as instructed by Rhythm; and

(e)                                  perform only those services and activities mutually agreed upon by Rhythm and Manufacturer as being necessary or advisable in connection with the close-out of any pending Work Order(s).

14.5                        Return of Materials/Confidential Information. Upon the expiration or termination of this Agreement, each party will promptly return all Confidential Information of the other party that it has received pursuant to this Agreement as required by Section 10.3 and otherwise comply with the obligations set forth in Section 10.3. Manufacturer will also promptly return at Rhythm’s expense all Rhythm Materials, Rhythm Equipment, retained samples, data, reports and other property, information and know-how in recorded form that was provided by Rhythm, or developed in the performance of the Services, that are owned by or licensed to Rhythm.

14.6                        Inventories. Upon expiration or termination of this Agreement or a pending Work Order, Rhythm (a) shall purchase from Manufacturer any existing inventories of Product ordered under this Agreement that conforms to the Specifications and is Manufactured in accordance with cGMP (if applicable) and the Manufacturing Process, at the price for such Product set forth in the applicable Work Order, and (b) shall purchase any such Product in process held by Manufacturer as of the date of the termination, at a price to be mutually agreed (it being understood that such price will reflect, on a pro rata basis, work performed and non-cancelable out-of-pocket expenses actually incurred by Manufacturer with respect to the Manufacture of such in-process Product). Following any such purchase, if so directed by Rhythm in writing, Manufacturer shall dispose of such material at Rhythm’s cost.

14.7                        Payment Reconciliation. Within thirty (30) days after the close-out of a Work Order, Manufacturer will provide to Rhythm a written itemized statement of all work performed by it in connection with the terminated Work Order, an itemized breakdown of the costs associated with that work (including any outstanding costs for purchases under Section 14.6 or for Rhythm Equipment, and any irrevocable commitments made by Manufacturer in connection with any pending Work Order(s) prior to termination), and a final invoice for that Work Order. If Rhythm

18

has pre-paid to Manufacturer more than the amount in a final invoice then Manufacturer agrees to promptly refund that money to Rhythm, or to credit the excess payment toward another existing or future Work Order, at the election of Rhythm.

14.8                        Survival. Expiration or termination of this Agreement for any reason will not relieve either party of any obligation accruing prior to such expiration or termination. Further, the provisions of Sections 1, 2.3, 4 (except for the first two sentences of Section 4.1 and the first sentence of Section 4.3), 5.2(c), 5.2(d), 5.4 through 5.7, 6, 9, 10, 12, 13, 14.4 through 14.8 and 15, and the provisions of any applicable Quality Agreement, will survive any termination or expiration of this Agreement.

15.                               Miscellaneous.

15.1                        Independent Contractor. All Services will be rendered by Manufacturer as an independent contractor for federal, state and local income tax purposes and for all other purposes. Manufacturer will not in any way represent itself to be a partner or joint venturer of or with Rhythm. This Agreement does not create an employer-employee relationship between Rhythm on the one hand and Manufacturer or any employee, subcontractors, Affiliate of Manufacturer, or any Manufacturer personnel on the other. Manufacturer is acting under this Agreement as an independent contractor with full power and authority to determine the means, manner and method of performance of Manufacturer’s duties. Manufacturer shall be responsible for and shall withhold and/or pay any and all applicable federal, state or local taxes, payroll taxes, workers’ compensation contributions, unemployment insurance contributions, or other payroll deductions from the compensation of Manufacturer’s employees and other Manufacturer personnel. Manufacturer understands and agrees that it is solely responsible for such matters and that it will indemnify Rhythm and hold Rhythm harmless from all claims and demands in connection with such matters.

15.2                        Force Majeure. Except as otherwise expressly set forth in this Agreement, neither party will have breached this Agreement for failure or delay in fulfilling or performing any term of this Agreement when such failure or delay is caused by or results from causes beyond the reasonable control of the affected party, including, without limitation, fire, floods, embargoes, shortages, epidemics, quarantines, war, acts of war (whether war be declared or not), insurrections, riots, civil commotion, strikes, acts of God or acts, omissions, or delays in acting, by any governmental authority (“force majeure”). The party affected by any event of force majeure will promptly notify the other party, explaining the nature, details and expected duration of the force majeure event. Such party will also notify the other party from time to time as to when the affected party reasonably expects to resume performance in whole or in part of its obligations under this Agreement, and to notify the other party of the cessation of any such event. A party affected by an event of force majeure will use its reasonable efforts to remedy, remove, or mitigate such event and the effects of it with all reasonable dispatch. If a party anticipates that an event of force majeure may occur, such party will notify the other party of the nature, details and expected duration of the force majeure event. Upon termination of the event of force majeure, the performance of any suspended obligation or duty will promptly recommence.

15.3                        Notices. All notices must be in writing and sent to the address for the recipient set forth in this Agreement below or in a subsequent notice as the recipient may specify in writing under this procedure. All notices must be given (a) by personal delivery, with receipt acknowledged, or (b) by first class, prepaid certified or registered mail, return receipt requested, or (c) by prepaid international express delivery service. Notices will be effective upon receipt or at a later date stated in the notice.
