Exhibit 10.37

EMPLOYMENT AGREEMENT

ThisEMPLOYMENT AGREEMENT(the "Agreement") is entered into as of December 10, 2003 by and between
Specialty Laboratories, Inc., a California corporation (the "Company"), and Maryam Sadri ("Executive"), and is effective upon execution by the Executive and approval by the Compensation
Committee of the Company's Board of Directors (the "Compensation Committee").

1.Duties and Responsibilities.

A.    Executive
shall serve as the Company's Vice-President, Laboratory Operations or such other title or position as may be designated from time to time by the
Board of Directors.

B.    Executive
agrees to devote his/her full time and attention to the Company, to use his/her best efforts to advance the business and welfare of the Company, to render
his/her services under this Agreement fully, faithfully, diligently, competently and to the best of his/her ability, and not to engage in any other employment activities to the extent such other
employment interferes with the Company's business or the performance of the Executive's duties hereunder.

C.    Executive
shall be based at the Company's office located in Santa Monica, California (which the Company may move to Valencia, California), but Executive may be required
to travel to other geographic locations in connection with the performance of his/her Executive duties.

2.Period of Employment.

Executive's
employment with the Company shall be governed by the provisions of this Agreement for the period commencing December 10, 2003 and continuing until this Agreement
terminates pursuant to written notification by either the Company or Executive, which notification may occur at any time for
any reason or no reason. The period during which the Executive provides services to the Company pursuant to this Agreement shall be referenced in this Agreement as the "Employment Period."

3.Cash Compensation.

A.    Executive's
base salary shall be payable in accordance with the Company's standard payroll schedule ("Base Salary"). Executive's compensation shall be subject to periodic
review by the Company, and may be increased or decreased in the Company's discretion with approval of the Compensation Committee.

B.    For
each fiscal year during the Employment Period, Executive shall be eligible for an incentive bonus in the Company's sole discretion ("Incentive Bonus"). For each full
fiscal year of employment during the Employment Period, Executive shall be eligible for an Incentive Bonus, targeted at twenty percent (20%) of his/her annual base salary. The Incentive Bonus amount
will be based on a number of factors, including but not limited to: (1) the financial performance of the Company as determined and measured by the Company's Board of Directors, and
(2) Executive's achievement of management targets and goals as set by the Company. The Incentive Bonus amount is intended to reward contribution to the Company's performance over an entire
fiscal year, and to encourage continuing contribution, and consequently will be paid only if Executive is employed and in good standing at the time of bonus payments, which generally occurs within
ninety (90) days after the close of the Company's fiscal year. Determination of the amount of Incentive Bonus, or whether any Incentive Bonus shall be paid, will be made in the Company's sole
discretion.

C.    The
Company shall deduct and withhold from the compensation payable to Executive hereunder, including the Incentive Bonus (if any), any and all applicable Federal, state
and local income and employment withholding taxes and any other amounts required or authorized by Executive to be deducted or withheld by the Company under applicable statutes, regulations, ordinances
or orders governing or requiring the withholding or deduction of amounts otherwise payable as compensation or wages to employees.

4.Equity Participation.

Pursuant
to the Company's 2000 Stock Incentive Plan, Executive may have previously been granted a specific number of options to purchase shares of the Company's common stock (the
"Options"), with certain vesting schedules and exercise prices, and except as specifically detailed herein, such grants remain in effect and are not affected by this Agreement.

5.Expense Reimbursement.

In
addition to the compensation specified in Section 3, Executive shall be entitled, in accordance with the Company's reimbursement policies in effect from time to time, to
receive reimbursement from the Company for reasonable business expenses incurred by Executive in the performance of his/her duties hereunder, provided Executive furnishes the Company with vouchers,
receipts and other details of such expenses in the form required by the Company sufficient to substantiate a deduction for such business expenses under all applicable rules and regulations of Federal
and state taxing authorities.

6.Fringe Benefits.

A.    Executive

all group term life insurance plans, group health plans, accidental death and dismemberment plans and short-term disability programs and other Executive perquisites which are made
available to the Company's Executives and for which Executive qualifies. The Company's Employee Handbook, copies of which Executive acknowledges were provided to Executive by Company, set forth
further information concerning these benefits.

B.    Executive
shall earn vacation time during the Employment Period at the rate of three (3) weeks per year. Vacation shall accrue and be taken pursuant to the
Company's vacation benefit policy set forth in the Company's Employee/Team Member Handbook, up to a maximum accrual of 160 hours, or four (4) weeks, of unused vacation time. Once this
maximum accrual is reached, the accrual will stop until Executive reduces the vacation balance by taking vacation time.

7.Severance Pay for Exercise of the At-Will Clause.

A.    Notwithstanding
any of the provisions of this Agreement, Executive's employment with the Company is "at will", which means that it is not for a specific term and may be
terminated by either the Company or Executive at any time, for any reason or no reason, without advance notice. Similarly the Company may change the terms and conditions of Executive's employment at
any time, for any reason, without advance notice.

B.    Should
the Company terminate Executive's employment for Cause (as defined in Section 9 below), or should Executive voluntarily resign (other than a resignation for
Good Reason (as defined in Section 8 below)), the Company shall have no obligation to Executive under this Agreement other than for accrued but unpaid salary and vacation time as of the date of
termination.

C.    If
the Company terminates Executive's employment other than for Cause, or if Executive resigns for Good Reason, the Company shall pay to Executive (in either a lump sum
or on a bi-weekly basis, at the sole discretion of the Company) severance pay in the amount equivalent to nine (9) months of Executive's Base Salary immediately preceding such
termination of Executive's employment,andCompany shall also make a lump sum payment to Executive of an amount equivalent to the payments necessary for
continuation of Executive's health benefits for nine (9) months under COBRA (such payments collectively "Severance Compensation"). Any election of coverage under COBRA will be at Executive's
sole discretion and expense. Executive must comply with the terms and conditions of COBRA to establish and maintain eligibility. In the event the provisions of this Section 7(C) are
implemented, upon the payment of the Severance Compensation and any accrued but unpaid salary and vacation time as of the date of termination have been paid to Executive, the

associated with, an entity or person that is engaged in a business or enterprise that directly competes with the Company. Consequently, if in any period during which the Executive is receiving
payments from the Company as a severance benefit, including but not limited to severance pay pursuant to Section 7, Executive shall, without prior written consent of the Company's Board of
Directors, directly or indirectly own, manage, operate, join, control or participate in the ownership, management, operation or control of, or be employed by, render service to or be connected in any

any company or other enterprise.

B.    During

benefit,including but not limited to severance pay pursuant to Section 7, Executive shall not encourage or solicit any of the Company's
employees to leave the Company's employ for any reason or interfere in any other manner with employment relationships at the time existing between the Company and its employees. In addition, Executive

in any other manner with any existing business relationship between the Company and any client or other third party.

C.    Executive
acknowledges that monetary damages may not be sufficient to compensate the Company for any economic loss which may be incurred by reason of his/her breach of
the foregoing restrictive covenants. Accordingly, in the event of any such breach, the Company shall, in addition to the termination of this Agreement and any remedies available to the Company at law,
be entitled to obtain equitable relief in the form of an injunction precluding Executive from continuing such breach.

signed by Executive and an authorized officer of the Company. Any and all prior agreements, understandings or representations relating to the Executive's employment with the Company are terminated and
cancelled in their entirety and are of no further force or effect.

provisions of this Agreement will be construed and interpreted under the laws of the State of California. If any provision of this Agreement as applied to any party or to any
circumstance should be adjudged by a court of competent jurisdiction to be void or unenforceable for any reason, the invalidity of that provision shall in no way affect (to the maximum extent
permissible by law) the application of such provision under circumstances different from those adjudicated by the court, the application of any other provision of this Agreement, or the enforceability
or invalidity of this Agreement as a whole. Should any provision of this Agreement become or be deemed invalid, illegal or unenforceable in any jurisdiction by reason of the scope, extent or duration

breach
hereunder or may pursue any other remedy by law or equity, whether or not stated in this Agreement.

19.Arbitration.

A.    Except
as provided for in Section 12(C), and to the fullest extent allowed by law, any controversy or claim arising out of or relating to Executive's employment
with the Company or anything set forth herein, shall be settled by final and binding arbitration, conducted in Los Angeles County, by an arbitrator selected in accordance with the procedure set forth
below. Possible disputes covered by the foregoing, include (without limitation) claims pursuant to Title VII of the Civil Rights Act, the California Fair Employment and Housing Act and comparable
statutes in other states if applicable, the Americans with Disabilities Act, the Age Discrimination in Employment Act, and any other statutes relating to an employee's relationship with his/her
employer. The Executive and the Company shall initially confer and attempt to reach agreement on the individual to be appointed as the arbitrator. If no agreement is reached, the Executive and the
Company shall request from the Judicial Arbitration and Mediation Services ("JAMS") a list of five (5) retired judges affiliated with JAMS. The Executive and the Company shall each alternately
strike names from such list until only one (1) name remains, and such person shall thereby be selected as the arbitrator. Except as otherwise provided for herein, such arbitration shall be
conducted in conformity with the procedures specified in the California Arbitration Act (Cal. C.C.P. §§ 1280et seq.). The
arbitrator shall allow the discovery authorized by California Code of Civil Procedure section 1283.05 or any other discovery required by law in arbitration proceedings. To the extent that
anything in this Agreement conflicts with the arbitration procedures required by applicable law, the arbitration procedures required by applicable law shall govern. The arbitrator shall issue a
written award that sets forth the essential findings and conclusions on which the award is based. The arbitrator shall have the authority to award any relief authorized by law in connection with the
asserted claims or disputes. The arbitrator's award shall be subject to correction, confirmation or vacation, as provided by any applicable law setting forth the standard of judicial review of
arbitration awards.

B.    The
Company shall bear the entire cost of (i) the arbitrator's fee, (ii) any other type of expense or cost that the Executive would not be required to bear
if the Executive were free to bring the dispute or claim in court and (iii) any other expense or cost that is unique to arbitration. The parties intend that this section describing arbitration
shall be valid, binding, enforceable and irrevocable and shall survive the termination of this Agreement. Any final decision of the arbitrator so chosen may be enforced by a court of competent
jurisdiction. The Executive acknowledges and agrees that he/she is waiving his/her right to a jury trial and agrees that the decision of the arbitrator shall be final and binding. Each party shall pay
its own costs and attorneys' fees, if any. However, if any party prevails on a statutory claim which affords the prevailing party attorneys' fees and costs, the Arbitrator may award reasonable fees
and costs to the prevailing party. Any dispute as to the reasonableness of any fee or cost shall be resolved by the Arbitrator.

Agreement may be executed in more than one counterpart, each of which shall be deemed an original, but all of which together shall constitute but one and the same instrument.
