     2. Option to Distribute Products.

     2.1 Distribution Options. Reva hereby grants to BSC an exclusive right with respect to each Jurisdiction on an exclusive basis (in each case, an “Option”), exercisable in each case in BSC’s sole discretion at any time during the Option Period, to sell, market and distribute Products in such Jurisdiction. BSC may exercise the Option with respect to any Jurisdiction by delivering written notice (each an “Option Exercise Notice”) to Reva at any time during the Option Period. Notwithstanding the foregoing, from and after such time, if any, that BSC first sells, markets or distributes any Directly Competitive Resorbable Stent Product in any Jurisdiction, then each Option shall become an option to obtain nonexclusive rights in such Jurisdiction solely with respect to the applicable Corresponding Stent Product and all exclusive arrangements in such Jurisdiction shall become nonexclusive in such Jurisdiction solely with respect to such Corresponding Stent Product.

     2.2 Exclusive Distribution Right. Reva hereby agrees that at all times prior to the expiration or termination of the Option Period, it will not market, sell or distribute any Product in any Jurisdiction or enter into any agreement or take any other action (including but not limited to, (i) granting any third party the right, or otherwise permitting any third party, to sell, market or distribute any Product in any Jurisdiction, (ii) entering into any distribution agreement with any third party in respect of any Product, and (iii) transferring or licensing to any third party any proprietary rights or other intellectual property) that would prevent or hinder BSC from exercising any Option; provided, however, that notwithstanding anything to the contrary in this Section 2, if BSC sells, markets or distributes any Directly Competitive Resorbable Stent

Product in any Jurisdiction, then Reva shall be entitled to market, sell and distribute the applicable Corresponding Stent Product in such Jurisdiction, or grant other parties the right to do so, in each case on a non-exclusive basis. Notwithstanding anything to the contrary herein, if (x) Reva receives Product Approval in respect of any Jurisdiction, or any country or territory within a Jurisdiction (in the case of the European Union), outside of the United States (each a “Foreign Jurisdiction”) with respect to any Product prior to the submission by Reva to the FDA of an application for Product Approval in the United States with respect to such Product, and (y) BSC does not deliver to Reva an Option Exercise Notice with respect to such Product and such Foreign Jurisdiction prior to the ninetieth (90th) day following receipt by BSC of a written inquiry from Reva (which written inquiry may not be delivered to BSC until after such time as Reva has obtained Product Approval in respect of such Product and such Foreign Jurisdiction) inquiring whether BSC intends to exercise the Option with respect to such Product and such Foreign Jurisdiction or BSC delivers an Option Exercise Notice with respect to such Product and such Foreign Jurisdiction but BSC and Reva are unable to agree upon the terms of a definitive distribution agreement prior to the expiration of the Negotiation Period, then Reva may sell, market and distribute such Product in such Foreign Jurisdiction directly or through any third party that is not a Direct Competitor, provided, however, that any and all distribution, reseller or similar agreement(s) entered into between Reva and any such third party shall be terminable, without cost or penalty to BSC, on no more than ninety (90) days’ written notice.

     2.3 Negotiation of Agreement.

          (a) If BSC exercises any Option(s), negotiations will begin as soon as reasonably practicable thereafter and the parties shall negotiate in good faith to enter into a mutually acceptable definitive distribution agreement with respect to such Option(s), which shall be prepared by BSC in a form reasonably acceptable to Reva, with customary terms and provisions, including without limitation, customary provisions relating to indemnification and representations and warranties covering, among other things, ownership, manufacturing, regulatory approvals, product quality, no liabilities, infringement and Intellectual Property coverage. In addition to such customary provisions, such definitive distribution agreement shall also include provisions that (i) Reva shall be obligated to meet all legal and regulatory requirements, as well as BSC quality standards, with respect to the design, development, and manufacturing of all Products and will contain all quality control provisions from BSC’s then current standard supplier quality agreement, (ii) the transfer price for Products shall be equal to fifty percent (50%) of BSC’s average selling price for such Products, (iii) the term of such distribution agreement shall not be less than five (5) years, (iv) BSC shall not be required to make any payments, other than payments of the aforementioned transfer price for Products, with respect to the sale, marketing or distribution of Products, (v) BSC shall be the exclusive distributor of the Products at all times during the term of such distribution agreement so long as BSC does not commence the selling, marketing or distributing of any Directly Competitive Resorbable Stent Product, with any such distribution agreement becoming non-exclusive with respect to (x) any Jurisdiction and (y) the applicable Corresponding Stent Product, at such time as BSC first sells, markets or distributes any Directly Competitive Resorbable Stent Product in such Jurisdiction, and (vi) BSC shall have sole discretion over all marketing and sales decisions relating to the Products.

          (b) If BSC and Reva are unable to agree upon the terms of a definitive distribution agreement through good faith negotiations with respect to any Option within ninety (90) days of BSC’s exercise of such Option (the “Negotiation Period”), or if BSC delivers at any time written notice to Reva that it elects not to exercise any Option, then Reva shall be permitted to sell, market and distribute Products in the Jurisdiction pertaining to any such Option itself or offer the right to sell, market and distribute Products in the Jurisdiction pertaining to any such Option to a third party, provided that, in the case of any such offer made to any such third party, the terms of such offer, and of any definitive agreement establishing such third party’s right to sell, market and distribute Products, shall not be materially more favorable than the most favorable terms offered by Reva to BSC at any time after the date of this Agreement and prior to the end of the Negotiation Period regarding BSC’s right to sell, market and distribute Products in the Jurisdiction pertaining to any such Option.

     2.4 Due Diligence. During any negotiation period for a distribution agreement contemplated by this Section 2, subject to the parties entering into a confidentiality agreement in form and substance reasonably acceptable to Reva, BSC shall be provided the opportunity to perform reasonable financial, legal, business and other due diligence regarding the Products. BSC shall not be required to enter into any distribution agreement with respect to any Option under any circumstances where it is not satisfied, in its sole discretion, with the results of such due diligence review. Reva shall provide BSC with reasonable cooperation in such due diligence review, including, allowing BSC access to its books, records, facilities and personnel.

3. Term and Termination.

     3.4 Effect of Termination. The parties acknowledge that upon termination of this Agreement as permitted under, and in accordance with the terms of this Section 3, no party shall have the right to recover any claim with respect to any losses suffered by such party in connection with such termination, except to the extent that such losses arise out of or are related to a breach of the agreements or covenants hereunder of another party hereto prior to or contemporaneous with such termination.

     3.5 Termination for Insolvency. This Agreement shall terminate without notice (a) upon the institution by or against BSC of insolvency, receivership or bankruptcy proceedings
