Except in any case where Executive’s attendance at legal proceedings is pursuant to subpoena or other legal process, written authorization by the Company’s Chief Executive Officer, Chief Financial Officer or Vice President Corporate

     (b) These additional separation benefits will become available only upon Executive’s execution of this Agreement and the expiration of the revocation period(s) set forth in Section 6 below (the “Effective Date”), and only if Executive has not revoked this Agreement pursuant to Section 6.

     (c) Executive further understands that the foregoing benefits are the only benefits she is entitled to receive from the Company for signing this Agreement, aside

		2		Initial:

from any retirement benefits to which Executive may be entitled under the Company’s 401(k) program.

     3. Personal Time-Off and Other Benefits. The Company agrees to compensate Executive for accrued, unused personal time-off earned through the Resignation Date (such amount to be paid with Executive’s last regular paycheck). Such payments shall be based on Executive’s final salary rate. Executive and the Company acknowledge and agree that, as of September 29, 2006, Executive had 166.27 accrued personal time-off hours. Executive expressly waives her right to any bonus payments under any of the Company’s bonus plans or programs or future stock option grants, except as otherwise determined by the Company’s Board of Directors. Executive acknowledges and agrees that upon her receipt of (a) the foregoing accrued personal time-off, (b) salary through the Resignation Date and (c) the other benefits described in Section 2 above, she will have received full payment and all monies that she earned or was otherwise entitled to during her employment by the Company, and that pursuant to Company policy she is entitled to no additional monies or benefits pursuant to her employment by the Company or as a result of her resignation.

     4. Mutual General Release.

          (a) Executive unconditionally, irrevocably and absolutely releases and discharges the Company and any parent and subsidiary corporations, divisions and affiliated corporations, partnerships or other affiliated entities of the Company, past and present, as well as any of their present and former employees, officers, directors, shareholders, consultants, insurers, representatives, lawyers, predecessors, agents, successors and assigns (collectively, “Released Parties”) and the Company hereby unconditionally, irrevocably and absolutely releases and discharges Executive from all claims related in any way to the transactions or occurrences between them to date, to the fullest extent permitted by law, including, but not limited to, Executive’s employment with the Company, the cessation of Executive’s employment, and all other losses, liabilities, claims, charges, demands and causes of action, known or unknown, suspected or unsuspected, arising directly or indirectly out of or in any way connected with Executive’s employment with the Company.

The parties hereto agree that this Agreement supersedes the Employment Arrangement, and that from the date hereof the Employment Arrangement will be null and void and of no further force or effect.

     (d) No provision of this Agreement may be modified or amended unless such modification or amendment is agreed to in writing and signed by duly authorized representatives of the parties hereto, which writing expressly states the intent of the parties to modify this Agreement.

     (e) This Agreement shall be construed as a whole in accordance with its fair meaning and in accordance with the laws of the State of California. The language in the Agreement shall not be construed for or against any particular party. The headings used herein are for reference only and shall not effect the construction of this Agreement.

     (f) Both Executive and the Company understand and agree that neither the payment of any sum of money nor the execution of this Agreement shall constitute or be construed as an admission of any liability whatsoever by either party.

     (g) The parties in good faith shall seek to amicably resolve any disputes arising out of or relating to this Agreement. If either party reasonably concludes that such a dispute will not be resolved despite such good faith efforts, following sixty (60) day prior written notice to the other party, such dispute shall be submitted to final, binding arbitration before JAMS. The arbitration shall be administered by JAMS pursuant to its Streamlined Arbitration Rules and Procedures, as modified below. The parties shall at all times and in good faith use reasonable efforts to resolve the dispute before an arbitration proceeding is instituted pursuant to this Agreement and shall, at all times after a dispute has been submitted to arbitration, continue to act in good faith and continue to use reasonable efforts to resolve the dispute. The arbitration shall take place in San Diego, California, before a sole mutually acceptable arbitrator, in accordance with the laws of the State of California for agreements made in and to be performed in that State and at the location designated by the arbitrator. The parties to the dispute may mutually agree to another location. If a party to a dispute fails to appear at any properly noticed arbitration proceeding, an award may be entered against such party notwithstanding such failure to appear. Judgment on the award may be entered in any court having jurisdiction. If the parties to the dispute are unable to agree on the choice for an arbitrator within ten (10) days after the matter has been submitted to arbitration, any party to the dispute may request JAMS to furnish to the parties a list of five (5) available arbitrators. After receipt of such list and an opportunity to consider the names, each party to the dispute may designate in writing to JAMS not more than two (2) names to be eliminated from the selection process. Failure of a party to the dispute to provide such designation in writing to JAMS within ten (10) days after such party’s receipt of the list of arbitrators from JAMS shall be deemed to be the party’s approval of all of the listed arbitrators. If more than one (1) name remains after such eliminations are timely made, the selection of the arbitrator shall be made by a lot from the remaining names. The expenses, wages and other compensation of any witnesses called before the arbitrator or any expert retained in connection with the arbitration shall be borne by the party to the

		7		Initial:

dispute calling the witnesses or retaining the expert, as applicable. The fee for the arbitration, the arbitrator’s fees and expenses, the cost of any hearing room, and the cost of a shorthand or similar reporter and the original transcript shall all be borne equally by the parties.

     (h) Notices and all other communications provided for in this Agreement shall be in writing and shall be deemed to have been duly given when delivered or mailed by U.S. Mail, return receipt requested, first-class or express postage prepaid, as follows:

EXHIBIT “A”

FORM OF CONSULTING AGREEMENT

     This Consulting Agreement (the “Agreement’) is entered into by and between Stratagene Corporation (the “Company”) and Ronni L. Sherman (the “Consultant”) effective as of October 13, 2006.

RECITALS

     WHEREAS, the Company and Consultant have entered into an Employment Separation Agreement and Mutual General Release of all claims (the “Separation Agreement”) dated October 6, 2006; and

     WHEREAS, in accordance with the Separation Agreement, both the Company and the Consultant believe that their mutual interests will be best served if the Company retains the services and expertise of the Consultant to provide consulting services to the Company as described herein.

AGREEMENT

     NOW, THEREFORE, in consideration of the mutual promises contained herein and for other good and valuable consideration, the adequacy of which is hereby acknowledged, the parties hereby agree as follows:

     1. Consultant Services. Consultant agrees, for the period October 13, 2006 until terminated pursuant to Section 8 hereof (the “Consulting Period”), to perform business advisory consulting services for the Company and its counsel and accountants (but not legal services), if and as requested and previously authorized by the Company’s Chief Executive Officer, Chief Financial Officer or Vice President Corporate Counsel. Consultant’s services shall be of an advisory nature and the Company shall not have any obligation to follow such advice. Consultant will be available and is obligated to provide services, as reasonably requested from time to time by the Company, so that the Company may obtain the full value of the retainer amounts stated in Section 2(b) of this Agreement.

     2. Compensation.

          (a) The Company shall pay Consultant at the rate of $250 per hour for any consulting services requested and provided pursuant to this Agreement. The Company agrees to increase this hourly rate to $350 solely for attendance at trials, depositions, arbitrations or other legal proceedings where Consultant’s presence as a witness or deponent was expressly requested and authorized by the Company; provided, however, that Consultant shall not be compensated for more than eight billable hours during any single calendar day for trial or deposition services.

          (b) The Company agrees that Consultant shall receive a $10,000 retainer payable in advance for each of the first four three-month periods after the date of this

		Exhibit A-1		Initial:

Agreement. Half of the amounts of the bills for services performed by Consultant will be credited first against any unused retainer amount and half of the amounts on the bills for services shall be paid by the Company by check or wire transfer (within ten (10) business days following receipt of invoices and descriptions therefor). At such point as the billings for such services rendered in any three-month period exceed $20,000 and the $10,000 retainer amount shall have been fully utilized, the Company will pay to Consultant by check or wire transfer any remaining amounts due for services rendered hereunder within ten (10) business days following receipt of invoices and descriptions therefor. In the event billings against the retainer for services requested and performed during any three-month period are less than $10,000, Consultant shall not be required to refund any unused retainer amounts to the Company. No further retainer amounts shall be required after the first twelve months of this Agreement. The retainer payments described herein are separate from, and in addition to, the payments described in Section 2(a)(iv) of the Separation Agreement.

     3. Independent Contractor. During the Consulting Period, Consultant will not be an employee of the Company, but will have the relationship of an independent contractor to the Company. As an independent contractor, Consultant shall have the sole responsibility and obligation to report his net earnings hereunder and otherwise as received as self-employment income on Consultant’s tax returns and to pay such taxes as are required by law. The parties agree that Consultant is an independent contractor and that, as such, the Company shall have no right, responsibility or obligation to withhold income or payroll taxes under the United States Insurance Contributions Act or under state unemployment, disability or other laws from amounts due to Consultant from the Company hereunder or to pay employer payroll taxes thereon under such laws or to withhold special or general funds, assessments, or taxes generally collected by employers for the use and benefit of employees.

     4. Cooperation. After the conclusion of the Consulting Period, Consultant agrees to cooperate fully with the Company and its counsel, accountants and investigators in its defense of, or other participation in, any administrative, judicial, or other proceeding arising from any charge, complaint, or other action which has been or may be filed relating to the period Consultant was engaged in consulting with the Company, on reasonable terms and with reasonable notice as shall be agreed by the parties.

     5. Proprietary/Privileged Information Clause. Consultant acknowledges that certain information, observations, and data obtained by her during the course of the term of this Agreement (including, without limitation, certain financial information, shareholder information, insurance information, business plans, marketing plans or proposals and/or customer lists and other customer information) are the sole property of the Company and constitute trade secrets of the Company. Consultant agrees to promptly return all files, customer lists, financial information, or other Company property without making copies thereof which are in Consultant’s possession or control; provided, however, that Executive shall retain any such materials to the extent reasonably necessary for her to provide the consulting services contemplated hereunder; and, provided, further, that Executive may retain any such materials that are publicly available or otherwise do not contain proprietary non-public information. Consultant further agrees that she will not disclose to any person or use any such privileged, confidential, or trade secret information, observations or data without the written consent of the Chief Executive Officer, Chief Financial Officer or Vice President Corporate Counsel of the Company, unless and to the extent that the aforementioned matters become generally known to and available for use by the public, other than as a result of Consultant’s acts or omissions to act,

		Exhibit A-2		Initial:

which acts or omissions were unauthorized and against the Company’s interest. Further, Consultant acknowledges that any unauthorized use of privileged, confidential or trade secret information will cause irreparable harm to the Company and will give rise to an immediate action by the Company for injunctive relief. If Consultant is served with a deposition subpoena or other legal process calling for the disclosure of such information, or if she is contacted by any third person requesting such information, she will immediately notify the Chief Executive Officer of the Company and will fully cooperate with the Company in minimizing the disclosure thereof.

     6. Remedies for Breach. In the event that Consultant willfully and materially breaches his obligations under this Agreement, in addition to whatever other rights the Company may have, Consultant shall forfeit his right to receive any further payments or benefits under this Agreement.

     7. Termination. This Agreement shall terminate on October 13, 2007 unless extended by mutual agreement of the parties.

     8. Non-Waiver of Breach. Either party may waive any breach of this Agreement by the other party, but no such waiver shall be deemed to have been given unless such waiver be in writing, signed by the waiving party and specifically designate the breach waived, nor shall any such waiver constitute a continuing waiver of similar or other breaches.

     9. Non-Assignment. Neither party may assign its obligations hereunder without the prior written consent of the other party.

     10. Miscellaneous Provisions.

     (a) Provisions of this Agreement are severable. If any provision is held to be invalid or unenforceable it shall not affect the validity or enforceability of any other provision.

     (b) Consultant acknowledges and agrees that she has read this Agreement carefully, understands all of its terms and agrees to those terms voluntarily.

     (c) This Agreement and the Separation Agreement represent the sole and entire agreements between the parties and, except as expressly stated herein, supersedes all prior agreements, negotiations and discussions between the Consultant and the Company with respect to the subject matters contained herein.

     (d) This Agreement shall be construed as a whole in accordance with its fair meaning and in accordance with the laws of the State of California. The language in the Agreement shall not be construed for or against any particular party. The headings used herein are for reference only and shall not affect the construction of this Agreement.

     (e) The parties agree that any and all disputes, controversies or claims arising out of or relating to this Agreement, or breach thereof, shall be submitted to final and binding arbitration. The arbitration shall take place in the State of California. Unless the parties mutually agree otherwise, the arbitration shall be conducted in the same manner provided under Section 16(g) of the Separation Agreement.

EXHIBIT “B”

AMENDMENT TO EMPLOYMENT SEPARATION AGREEMENT
AND MUTUAL GENERAL RELEASE OF ALL CLAIMS

     This Amendment to the Employment Separation Agreement and Mutual General Release of All Claims (“Amendment”) is made by Stratagene Corporation (the “Company”) and Ronni L. Sherman (“Executive”) and amends the Employment Separation Agreement and Mutual General Release of All Claims between those same parties (“Separation Agreement”) by extending the promises and mutual agreements of each and every paragraph and subparagraph except section 6 of the Separation Agreement through the Resignation Date.

     This Amendment also is intended to satisfy the Older Workers’ Benefit Protection Act, 29 U.S.C. Section 626(f). Accordingly, by signing this Amendment where indicated below, Executive acknowledges that (a) she has read and understands the terms of this Amendment, (b) she has been advised to consult an attorney at her own expense, if desired, and (c) she has considered such legal counsel as she deems necessary, such that she is signing this Amendment freely, knowingly and voluntarily. Executive acknowledges she will have twenty-one (21) days to consider whether or not to sign this Amendment (although she may elect not to use the full 21-day period at her option). After Executive signs this Amendment, she will promptly deliver it to the Company. Release of any Age Discrimination in Employment Act (ADEA) claims contained in this Amendment shall not become effective or enforceable until the eighth day after the Amendment is signed (“Amendment Effective Date”). The remaining provisions of this Amendment, except for release of any ADEA claims, will remain in effect notwithstanding any revocation. In other words, Executive may revoke her acceptance of this Amendment to the extent it releases any ADEA claims within seven (7) days after she signs it. Executive’s revocation must be in writing and received by the Company, on or before the seventh day after it is signed, to be effective. If Executive does not revoke her acceptance on or before that date, her acceptance of the release of her ADEA claims contained in this Amendment shall become binding and enforceable on the eighth day after it is signed.
