In consideration of the mutual covenants and promises herein contained, and other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the parties do hereby agree as follows:

1.         Professional Services. BioBridges is engaged in the business of providing its professionals ("Professionals") to perform services for clients including those relating to pharmaceutical clinical trials and development.

Should any terms and conditions set forth in the Service Order conflict with the terms and conditions contained in this Agreement, the terms and conditions set forth in the Service Order will be understood to govern the agreement between the parties only if specifically stated as superseding a specific provision in the Agreement.

2.          Service Orders. During the term of this Agreement, BioBridges and Client will execute a Service Order for each project for which Client requires BioBridges Professionals (a "Project"). Upon execution of the applicable Service Order, Client will accept BioBridges Professionals to perform services for Client for the duration of time stated in said Service Order (the "Services"), subject to the terms and conditions of this Agreement. The parties agree that the terms and conditions of this Agreement shall apply to each such Service Order executed by the parties. Each Service Order shall set forth: (a) a description of the Services to be performed; (b) the term of the Service Order, (c) the location and timing of performance; and (d) any other terms and conditions applicable to the Services in question. No Service Order will be binding upon BioBridges or Client unless executed by both parties.

(a)        BioBridges shall provide certain Services for Client Projects on a time and materials basis as set forth in the applicable Service Order. Client agrees to pay BioBridges for Services at the rates stated in the applicable Service Order.

15.       Indemnification. Each party (the "Indemnifying Party") shall indemnify, defend and hold the other party, its affiliates, and their officers, directors, agents, employees, and independent contractors and their successors and assigns (each, an "Indemnified Party") harmless from and against any and all liability, obligation, damages, loss, award, fme, fee, charge, cost or expense of any kind, character or description (including reasonable legal fees) arising out of a claim, demand, suit, action or proceeding (each, a "Claim") brought by a third party against an Indemnified Party based upon or related to: (i) bodily injury or property damage caused by the gross negligence or willful misconduct of the Indemnifying Party; or (ii) the Indemnifying Party's material breach of this Agreement, except to the extent a Claim is the result of the gross negligence or willful misconduct of the Indemnified Party.

17.        Equitable Relief. Each party hereto agrees that because monetary damages will be inadequate in the event of its breach or threatened breach of its obligations of confidentiality and/or non-solicitation under Sections 10, 11or 12 of this Agreement, the other party hereto shall also be entitled to injunctive relief and/or specific performance with respect to any such breach.

Client will be free to use Deliverables for any and all legal purposes.

19.        Term and Termination.

Client may immediately terminate the Services of any BioBridges Professional, upon five (15) days written notice, with or without cause. No termination of this Agreement or any Service Order shall affect the obligation of Client to pay all amounts due to BioBridges for Services rendered and costs and expenses incurred through the date of termination of Services, as well as any termination fees if required pursuant to a Service Order. Upon termination of this Agreement for any reason, neither party shall have any further liability or obligation to the other party except for the payment of Services rendered, and reimbursement of costs and expenses incurred by BioBridges through the date of termination, and, if applicable, termination fees as may be required pursuant to a Service Order, except that the provisions of Sections 3, 4, 10, ll, 12, 15, 16, 17 18, 19, 20, and the Mutual NDA shall survive any termination of this Agreement.

22.        General Provisions.

If any provision in this Agreement shall be held to be excessively broad, it shall be construed by limiting it so as to be enforceable to the extent compatible with applicable law.
