This agreement shall commence May 1, 2009 and continue for a term of two (2) years.

2. HEMACARE'S COMPENSATION. For Services rendered on or after May 1, 2009 pursuant to this Agreement, Hospital shall pay HemaCare in accordance with the revised Fee Schedule, Attachment “I,” attached hereto and made part hereof by this reference. At the end of the initial twelve (12) months of this contract term, the parties agree to meet and confer regarding the fees for services rendered during the remainder of the term. Any modifications to the Fee Schedule shall take effect only upon mutual written agreement of both parties and shall apply to services rendered on or after the date of such mutual written agreement.

3. GENERAL. If provisions of this Amendment and the Agreement conflict, the provisions of this Amendment shall prevail. Except as specifically amended herein, all terms and conditions of the Agreement shall remain in full force and effect.

4. LIMITED EXCLUSIVITY. Section V, paragraph E of the Agreement shall be amended and is replaced in its entirety as follows:

1

It is agreed and acknowledged by the parties that, as an independent contractor, HemaCare retains the right to contract with and provide services to entities and individuals other than Hospital and its patients, and nothing in this Agreement be interpreted as limiting or restricting in any way HemaCare's right to do so. Hospital agrees that HemaCare will be the sole outside provider of the described Blood Donor Center and Community Mobile Blood Drive Program during the term of this Agreement and Hospital agrees not to contract with any other third party to conduct the Services contemplated by this Agreement, unless HemaCare is unable to meet and/or perform its obligations under this Agreement or as otherwise provided herein. Nothing in the foregoing sentence shall prohibit Hospital from purchasing blood products from any vendor at any time. Upon mutual written agreement of both parties HemaCare may open complimentary Donor Centers for benefit of the Hospital.

5. NON-SOLICITATION. Section VIII, paragraph C of the Agreement shall be amended and is replaced in its entirety as follows:

HemaCare and Hospital mutually agree not to solicit each other's employees, except upon written permission. The prohibition period for non-solicitation will extend for twenty-four (24) months post-HemaCare or Hospital employment and for twenty-four (24) months after the termination off this agreement. The penalty for breach will be an amount equal to the employee's annual compensation prior to termination of services with the aggrieved party. Nothing in the foregoing covenant shall restrict either party from entering into employment discussions with an employee of the other party who initiates such discussions.

6. ASSIGNMENT. Section VIII, paragraph F of the Agreement shall be amended and is replaced in its entirety as follows:

Neither party may assign this Agreement, nor the rights and obligations therein, to a third party without the express written consent of the other party; however, either party may assign this Agreement, and its rights and obligations therein, to any individual or entity that purchases all or substantially all of either party's assets or stock, or any entity that succeeds to a merger between either party and another entity or entities, or to any entity controlled by either party, or to any entity controlling either party, or any entity under common control with either party.

7. LIMITATION OF LIABILITY. Section VIII, paragraph K, shall be added and incorporated to the Agreement as follows:

The parties acknowledge and agree that both Hospital and HemaCare shall only be entitled to reasonably foreseeable direct damages, if any, which arise from (i) any indemnification provision under this Agreement, as amended, (ii) any beach of any provision under this Agreement, as amended, and (iii) any breach under Section VIII, paragraph C of the Agreement, as amended, which relates to the non-solicitation of employees and the penalty associated therewith. Except for direct damages as provided in the preceding sentence, to the maximum extent permitted by law, it is the intent of the parties that neither Hospital nor HemaCare shall be responsible for any incidental, consequential, indirect, special, punitive or exemplary damages of any kind, including damages for lost goodwill, lost profits, lost business or other indirect damages based on contract, negligence, tort (including strict liability) or other legal theory, as a result of a breach of any warranty or any other term of this Agreement, and regardless of whether a party was advised or had reason to know of the possibility of such damages in advance.
