(b) Upon making any payment to an Indemnified Person in respect of any Losses, the Indemnifying Person will, to the extent of such payment, be subrogated to all rights of the Indemnified Person (and its Affiliates) against any third party in respect of the Losses to which such payment relates.

WHEREAS, Licensor and Licensee (each a “Party” and, collectively, the “Parties”) have entered into that certain Asset Purchase Agreement dated September _____, 2008 (the “Asset Purchase Agreement”), pursuant to which, among other things, Licensee has agreed to acquire, and Licensor has agreed to sell, the Licensor’s urokinase business franchise;

WHEREAS, the assets to be transferred include Labeled Inventory of the Products (each, as defined in the Asset Purchase Agreement); and

NOW, THEREFORE, in consideration of entering into the Asset Purchase Agreement and the mutual agreements and undertakings contained herein and for other good and valuable consideration (the receipt and sufficiency of which is hereby acknowledged), the Parties agree as follows.

1. DEFINITIONS:

Capitalized terms used in this Agreement and not otherwise defined herein shall have the respective meanings assigned to them in the Asset Purchase Agreement. For purposes of this Agreement, the following words and phrases shall have the following meanings:

1.1 “Licensed Marks” shall mean those trademarks identified on Schedule 1 attached hereto.

-1-

2. GRANT

2.1 During the term of this Agreement, and subject to the terms and conditions hereof and of the Asset Purchase Agreement, the Licensor hereby grants to the Licensee, in the Territory, an exclusive, fully paid-up, non-transferable and non-assignable license, without the right to sublicense other than as provided herein (“Inventory Trademark License”), to use the Licensed Marks solely in connection with the promotion, marketing and sale of the Labeled Inventory in the Territory.

2.2 Notwithstanding anything else in this Agreement to the contrary, absent Licensor’s express prior written consent, Licensee’s use of the Licensed Marks shall cease at the end of the earlier of (i) the completion of the sale of all Labeled Inventory by Licensee, and (ii) the date upon which the expiration date for all Labeled Inventory has expired, at which time the Inventory Trademark License shall automatically terminate without further action by either Party and Licensee shall cease all use of the Licensed Marks, except for commercially reasonable ancillary use to the extent required for regulatory purposes relating to the Labeled Inventory for a period of up to 24 months after the termination of this Agreement and except for any fair use of the Licensed Marks as defined by the relevant trademark laws.

2.3 Deleted.

2.4 Without the prior written consent of Licensor, Licensee shall have no power or right to, and shall not, sell, assign, sublicense or otherwise transfer the Inventory Trademark License to any Person, including by operation of law, except for (i) sublicensing, with Licensor’s prior written consent (which consent the Licensor shall not unreasonably withhold or delay), within Licensee’s trade channels solely for the purposes of selling and marketing the Labeled Inventory, and (ii) to any permitted assignee of Licensee’s rights and obligations under the Asset Purchase Agreement to the extent permitted therein. It is hereby understood and agreed that use of the Licensed marks by distributors, wholesalers and resellers of Licensee in connection with the promotion and sale of the Labeled Inventory is not considered to constitute a sublicense and is specifically consented to by Licensor.

3.3 Deleted.

3.4 Licensee shall not use the Licensed Marks other than as permitted hereunder and, in particular, shall not incorporate Licensor’s name or the Licensed Marks in Licensee’s corporate or business name in any manner whatsoever. In using the Licensed Marks, Licensee will in no way represent that it has any rights, title or interest in the Licensed Marks other than those expressly granted under the terms of this Agreement, and Licensee shall not represent itself as an “authorized representative of,” or indicate in any other way any affiliation with, Licensor other than the relationship created pursuant hereto or the Asset Purchase Agreement.

3.7 Licensee agrees not to knowingly adopt or use any trade name or trademark which is confusingly similar or likely to cause confusion with the Licensed Marks. Furthermore, Licensee agrees not to knowingly seek registration of any of the Licensed Marks or any trade name or trademark confusingly similar thereto.

4. QUALITY CONTROL

4.1 Licensee shall use the Licensed Marks only with respect to the promotion, marketing and sale of the Labeled Inventory as provided herein, and shall not affix any Licensed Marks to any products other than Products, or use any Licensed Marks in connection with any service (other than as necessary to market and sell Products).

4.2 All Products promoted, marketed and sold by Licensee under the Licensed Marks have been made by Licensor and thus are of the same quality as the Products sold by Licensor under the Licensed Marks immediately prior to the Closing Date, and Licensee shall otherwise use the Licensed Marks in a manner consistent with Licensor’s use, immediately prior to the Closing Date, of the Licensed Marks in connection with the Products. At Licensor’s request, and upon reasonable notice Licensee shall provide to Licensor representative samples of Licensee’s use of the Licensed Marks.

4.3 In using the Licensed Marks as permitted hereunder in connection with the promotion, marketing and sale of the Labeled Inventory, Licensee shall duly include all notices and legends with respect to the Licensed Marks as may be required by applicable federal, state or local trademark laws or which may be reasonably requested by Licensor in writing.

14. CONSTRUCTION

The language in all parts of this Agreement shall be construed, in all cases, according to its fair meaning. The Parties acknowledge that each Party and its counsel have reviewed and revised this Agreement and that any rule of construction to the effect that any ambiguities are to be resolved against the drafting Party shall not be employed in the interpretation of this Agreement. Words in the singular shall be deemed to include the plural and vice versa and words of one gender shall be deemed to include the other gender as the context requires. The terms “hereof,” “herein,” and “herewith” and words of similar import shall, unless otherwise stated, be construed to refer to this Agreement as a whole and not to any particular provision of this Agreement. Article, Section and Schedule references are to the Articles, Sections and Schedules to this Agreement unless otherwise specified. Unless otherwise stated, all references to any agreement shall be deemed to include the exhibits, schedules and annexes to such agreement.

This Agreement and the provisions of any other agreement specifically referenced herein constitute the entire understanding between the parties concerning the subject matter hereof and supersede all written or oral prior agreements or understandings with respect thereto. No waiver or modification of any terms of this Agreement shall be valid unless in writing and signed by an authorized representative of both parties. The failure of either Party to enforce any condition or part of this Agreement at any time shall not be construed as a waiver of that condition or part, nor shall it forfeit any rights to future enforcement thereof.

16. SEVERABILITY

In the event that any provision of this Agreement is judicially determined to be void or unenforceable, such provision shall be construed to be separable from the other provisions of this Agreement which shall retain full force and effect. Upon severance of a provision herein the parties shall cooperate to replace such provision as permitted by law so as to replicate the intention of the parties in entering into this Agreement.
