This Employment Agreement (this “Agreement”) is entered into as of August 29, 2006 (the “Effective Date”), by and between Teragenix Corporation, a Florida corporation (the “Company”), and Joseph Mauro (“Executive”) (together, the “Parties”).

INTRODUCTION

WHEREAS, the shareholders of the Company and HemaCare Corporation, a California corporation (“HemaCare”) are entering into that certain Stock Purchase Agreement of even date herewith (the “Stock Purchase Agreement”);

WHEREAS, it is a condition to the consummation of the transactions contemplated by the Stock Purchase Agreement that the Company and Executive enter into this Agreement; and

WHEREAS, the Company desires to employ Executive as of the Effective Date and Executive desires to accept employment with the Company on the terms and conditions set forth below.

NOW, THEREFORE, in consideration of the foregoing recital and the respective covenants and agreements of the Parties contained in this document, the Company and Executive agree as follows:

1. Employment.

(a) Title; Duties. During the Term, Executive will serve as Division President of the Company, and will report directly to HemaCare’s President and Chief Executive Officer (“CEO”). Executive shall have such duties consistent with that of a President that may from time to time be designated or assigned to Executive pursuant to the directives of HemaCare’s President and CEO. Executive shall perform faithfully the duties assigned to him to the best of his ability.

(b) Other Activities. During the Term, Executive shall devote his entire productive business time and attention to his duties on the Company’s behalf except for sick leave, vacations and approved leaves of absence; provided, however, that nothing in this Agreement shall prohibit Executive from (i) serving as a director of any entity or business enterprise which is not in direct competition with the business of the Company or any present or future affiliate of the Company and which does not create a real or perceived conflict of interest, (ii) otherwise participating in educational, welfare, social, religious and civic organizations or (iii) making any investments (other than “passive investments,” as defined below) in the securities of any entity or business enterprise which is not in direct competition with the business of the Company or any present or future affiliate of the Company and which does not create a real or perceived conflict of interest; provided, that Executive obtains the prior approval of the CEO with respect to any position described in clause (i) of this Section 1(b) and any investment (other than any “passive investments”) described in clause (iii) of this Section 1(b), which approval shall not be unreasonably withheld, delayed or conditioned. An investment shall be

considered a “passive investment” to the extent that such securities (x) are actively traded on a United States national securities exchange, on the NASDAQ National Market System or Small Cap Market System, on the OTC Bulletin Board, or on any foreign securities exchange, and (y) represent, at the time such investment is made, less than five percent (5%) of the aggregate voting power of such entity or business enterprise.

2. Employment Term. Subject to Section 9, Executive’s employment hereunder shall be for a term of thirty-six (36) months commencing on the Effective Date and expiring at the close of business on the day prior to the thirty-six (36) month anniversary of the Effective Date (the “Term”). This Agreement shall automatically renew for successive one (1) year periods following the initial Term and any extensions thereof, if applicable, unless either party provides written notice to the other party not less than ninety (90) days prior to the end of the then-existing Term, that such party does not desire the Term to automatically renew, in which event this Agreement shall terminate as of the last day of the then-existing Term.

3. Place of Employment. Executive’s services shall be performed at the Company’s principal executive offices located at 5440 NW 33rd Avenue, Suite 108, Ft. Lauderdale, Florida 33309 or such other place as the Company and Executive shall mutually agree.

4. Salary. For all services rendered by Executive hereunder and all covenants and conditions undertaken by him pursuant to this Agreement, the Company shall pay, and Executive shall accept, as full compensation, the amounts set forth in this Section 4.

a. Base Salary. For all services to be rendered by Executive pursuant to this Agreement, the Company agrees to pay Executive a base salary (the “Base Salary”) of One Hundred and Seventy-Five Thousand Dollars ($175,000.00) on an annualized basis. The Base Salary shall be paid in accordance with the Company’s regular payroll practices. All amounts payable shall be reduced by standard withholding and other authorized deductions. The Company, in its sole discretion, may increase (but not decrease) the Base Salary from time to time, provided, however, that commencing January 1, 2008, the Base Salary shall increase at a minimum level of 3% per annum during each year of the Term.

b. Bonus. Executive shall be eligible for a bonus of up to 20% of the Base Salary (the “Bonus”), starting in calendar year 2007, upon the achievement of specific goals and objectives, as determined in the sole discretion of HemaCare’s President and Chief Executive Officer. The Bonus structure will put 100% of Executive’s Bonus potential at risk each year. Executive must be employed by the Company at the time of payment to be eligible to receive any Bonus.

c. Car Allowance. During the Term, Executive shall receive a car allowance equal to $1,250 per month.

d. Life Insurance. The Company agrees to pay a whole life insurance policy for the Employee with a face amount equal to one times Executive’s salary.

e. Deductions. The Company shall deduct from the compensation described in Sections 4(a) and 4(b) any federal, state or local withholding taxes, social security

contributions and any other amounts which may be required to be deducted or withheld by the Company pursuant to any federal, state or local laws, rules or regulations.

f. Disability Adjustment. Any compensation otherwise payable to Executive pursuant to Sections 4(a) and 4(b) in respect of any period during which Executive is Disabled (as defined in Section 9(d)) shall be reduced by any amounts payable to Executive for loss of earnings or the like under any insurance plan or policy sponsored by the Company.

5. Expenses. The Company shall from time to time pay or reimburse Executive for the reasonable and necessary expenses incurred by Executive in connection with the performance of his duties hereunder if (a) such expenses have been previously approved by the Company or reimbursement is otherwise appropriate in accordance with the Company’s established policies and (b) the Company receives such verification thereof as the Company may require in order to qualify such expenses as deductible business expenses.

6. Other Benefits. In addition to his compensation provided by the foregoing, so long as Executive is employed by the Company, Executive shall be entitled to all of the benefits available (a) generally to Company employees pursuant to Company programs, and/or (b) to senior level executives at the Company, including, by way of illustration, personal leave, paid holidays, sick leave, profit-sharing, retirement, disability, dental, vision, group sickness, accident or health insurance programs or equity incentive plans of the Company which may now or hereafter be in effect, or in any other or additional such programs which may be established by the Company, as and to the extent any such programs are or may from time to time be in effect, as determined by the Company. The Company shall implement and maintain a health and medical plan as soon as is reasonably practical after the execution of this Agreement and maintain such plan throughout the Term. The Company shall have the right to amend, reduce or completely terminate any or all such plans by duly authorized action respecting all employees covered by such plans as a group.

7. Vacations and Holidays. During each calendar year, Executive shall accrue compensated personal time off (“PTO”) at the rate of twenty-nine (29) days per year. If Executive’s earned but unused PTO reaches forty-eight (48) days, Executive will not continue to accrue additional PTO time until he uses sufficient PTO to fall below this maximum amount. Thereafter, Executive shall start earning PTO benefits again until the forty-eight (48) day maximum is again reached. Any accrued but unused PTO time will be paid to Executive on a pro rata basis at termination of employment for any reason. Executive shall not be compensated for holidays (other than as part of the PTO system).

8. Other Activities. Executive shall, during the term of his employment by the Company, devote all of his working time and efforts to the business and affairs of the Company and its subsidiaries and to the diligent and faithful performance of the duties assigned to him pursuant to this Agreement.

9. Termination. The Company may terminate Executive’s employment for any reason or no reason, with or without Cause (as defined below), with the consequences described in Section 10 of this Agreement. Executive may terminate his employment with Good Reason (as defined below) by giving the Company thirty (30) days’ advance written notice. Upon

termination of Executive’s employment with the Company, Executive’s rights under any applicable benefit plans shall be determined under the provisions of those plans.

a. Death. Executive’s employment shall terminate immediately in the event of his death.

b. Cause. Subject to Executive’s failure to cure a breach in the manner and time described below, the Company may terminate Executive’s employment for Cause immediately. As used in this Agreement, the term “for Cause” shall be limited to a termination for the following acts by Executive: (i) misappropriation or embezzlement of the funds or property of the Company or any subsidiary, falsification of any Company or subsidiary documents or records or any unauthorized attempt by the Executive to take any business or business opportunities of the Company or any subsidiary for his or her own personal gain; (ii) Executive’s failure or inability to perform any material duties contemplated by this Agreement for a period of thirty (30) days, except in the event that the Executive is determined to have a Disability (as defined in Section 9(d)) or in the event of Executive’s death; (iii) grossly negligent, reckless or willful misconduct or insubordination in connection with Executive’s performance of his duties; (iv) any material breach by Executive of any agreement (including this Agreement or the Confidentiality Agreement (as defined in Section 11)) between Executive and the Company; (v) Executive’s conviction (including any plea of guilty or nolo contendere) of any felony, any misdemeanor involving dishonesty or fraud, or any other criminal act that impairs or could impair Executive’s ability to perform his or her duties; (vi) the Executive’s material violation of Company policies, including, without limitation, policies on prohibition of unlawful harassment or (vii) any illegal drug or illegal substance abuse, illegal drug or illegal substance addiction, or chronic addiction to alcohol on the part of Executive, other than any use of medication prescribed by a doctor. The determination of Cause shall be made by HemaCare’s President and Chief Executive Officer in her reasonable discretion. Anything herein to the contrary notwithstanding, as to any termination based upon clause (iii) above, the Company shall give the Executive written notice prior to terminating this Agreement of the Executive’s employment, setting forth a general description of the grounds for termination and the conduct required to cure such grounds for termination. The Executive shall have thirty (30) days from the receipt of such notice within which to cure any such grounds for termination to the satisfaction of the Company, which shall be determined by the Company in its reasonable discretion.

c. Termination by Executive for “Good Reason”. Subject to the provisions outlined below, at any time after the date Executive commences employment under this Agreement, upon thirty (30) days’ advance written notice to the Company of his intent to terminate the Agreement, Executive shall have the right to terminate his employment under this Agreement for “Good Reason”.

unless Executive shall have provided the Company with written notice of its alleged actions constituting Good Reason (which notice shall specify in reasonable detail the particulars of such Good Reason) and the Company has not cured any such alleged Good Reason within thirty (30) days of the Company’s receipt of such written notice.

d. Disability. The Company may terminate Executive’s employment for Disability by giving Executive three (3) days’ advance written notice. For all purposes under this Agreement, “Disability” shall mean that Executive, at the time such notice is given, has been unable to substantially perform his duties under this Agreement for a period of not less than three (3) consecutive months (or after four (4) months in the aggregate during a twelve-month period, whether consecutive or not) as the result of his incapacity due to physical or mental illness. A determination of Disability shall be made by the Board in consultation with a physician reasonably satisfactory to Executive (or his representative) and the Company, and Executive shall cooperate with the efforts to make such determination. Any such determination shall be conclusive and binding on the Parties for the purposes of this Agreement.

10. Termination Benefits. Upon the termination of Executive’s employment, Executive shall be entitled to receive:

a. Death or Disability. Executive shall be entitled to the following:

(i) Payment of any Base Salary accrued but unpaid as of the date of death or termination for Disability;

(iii) Reimbursement for any unpaid expenses incurred in accordance with Section 5; and

(iv) Payment of any and all earnouts, or other consideration amounts that the Company is obligated to pay pursuant to the Stock Purchase Agreement (but only if actually earned, and such amounts shall be paid on the date(s) provided in the Stock Purchase Agreement), and any bonuses earned as of the date of termination pursuant to Section 4(b) of this Agreement.

16. Integration.

17. Waiver. Failure or delay on the part of either Party hereto to enforce any right, power, or privilege hereunder shall not be deemed to constitute a waiver thereof. Additionally, a

waiver by either Party of a breach of any promise hereof by the other Party shall not operate as or be construed to constitute a waiver of any subsequent breach by such other Party.

19. Headings. The headings of the Sections contained in this Agreement are for reference purposes only and shall not in any way affect the meaning or interpretation of any provision of this Agreement.

20. Applicable Law. This Agreement shall be governed by and construed in accordance with the internal substantive laws, and not the choice of law rules, of the State of Florida.

21. Counterparts; Facsimile. This Agreement may be executed in one or more counterparts and via facsimile, none of which need contain the signature of more than one party hereto, and each of which shall be deemed to be an original, and all of which together shall constitute a single agreement.

22. Arbitration.

a. The Company and Executive agree that any dispute or controversy arising out of or relating to any interpretation, construction, performance, termination or breach of this Agreement or Executive’s employment with the Company or termination of such employment, will be settled by final and binding arbitration by a single arbitrator to be held in Los Angeles County, California, in accordance with the National Rules for the Resolution of Employment Disputes of the American Arbitration Association (“AAA Rules”) then in effect. Without limiting any other provision herein, this Section 22 shall survive the termination of Executive’s employment with the Company and will apply to any claim, dispute, or controversy that arises during or after the termination of Executive’s employment with the Company. Executive and the Company agree that the agreement to arbitrate under this Section 22 is subject to and enforceable under the provisions of the Federal Arbitration Act (the “FAA”), 9 U.S.C. § § I, et seq. The arbitrator selected shall have the authority to grant Executive or the Company or both all remedies otherwise available by law, including injunctions.

b. Notwithstanding anything to the contrary in the AAA Rules, the arbitration shall provide (i) for written discovery and depositions adequate to give the Parties access to documents and witnesses that are essential to the dispute and (ii) for a written decision by the arbitrator that includes the essential findings and conclusions upon which the decision is based. Consistent with applicable law, Executive and the Company shall each bear his or its own costs and attorneys’ fees incurred in conducting the arbitration and, except in such disputes where Executive asserts a claim under a state or federal statute prohibiting discrimination in

employment, a claim for wrongful termination in violation of public policy, or a claim involving enforcement of rights under any statute enacted for a public reason (the “Excepted Claims”), shall split equally the fees and administrative costs charged by the arbitrator and AAA. In disputes where Executive asserts an Excepted Claim against the Company, Executive shall be required to pay only the AAA filing fee to the extent such filing fee does not exceed the fee to file a complaint in state or federal court and the Company shall pay the balance of the arbitrator’s fees and administrative costs.

c. The decision of the arbitrator will be final, conclusive and binding on the Parties to the arbitration. The prevailing party in the arbitration, as determined by the arbitrator, shall be entitled to recover his or its reasonable attorneys’ fees and costs, including the costs or fees charged by the arbitrator and AAA. In disputes where Executive asserts an Excepted Claim, reasonable attorneys’ fees shall be awarded by the arbitrator based on the same standard as such fees would be awarded if the Excepted Claim had been asserted in state or federal court. Judgment may be entered on the arbitrator’s decision in any court having jurisdiction.

The parties hereby acknowledge that they have voluntarily negotiated the terms of this Agreement, including, without limitation, this Section 22, have consulted with counsel concerning such terms, and voluntarily agree to them.
