Re: Transition to Part-Time Employee

Dear Mr. Stuart:

This letter agreement (“Agreement”) sets forth the terms of your change in status from your current role as a full-time employee of Questcor Pharmaceuticals, Inc. (the “Company”) to a new role as a part-time employee of the Company for a six month transition period:

1. Transition Date. Your last day as the Company’s Senior Vice President and Chief Financial Officer, the Company’s Principal Accounting Officer and its Assistant Secretary, will be the earlier to occur of the following two dates: (i) the date upon which a new Chief Financial Officer begins his or her employment with the Company; or (ii) December 31, 2008 (the “Transition Date”). The Company will immediately initiate a search for a new Chief Financial Officer and may publicly announce this search. Until the Transition Date, you shall continue to use your best efforts to perform your currently assigned duties and responsibilities. During your continued employment in your current capacity through the Transition Date, you will receive your regular base salary payments and continued benefits coverage in which you are currently enrolled. Of course, you must continue to comply with all of the Company’s policies and procedures during your continued employment.

2. Post-Transition Date. On the Transition Date, you will continue to be an employee of the Company under the terms set forth in this Agreement, but you will no longer be an officer of the Company. Within five (5) business days of the Transition Date, you will use your best efforts to execute and deliver to the Company a “sub-certification” to support the certifications contemplated by Section 302 of the Sarbanes-Oxley Act of 2002. You agree to work a normal part-time work week and your compensation will be a gross amount of $17,333.33 per month ($8,666.67 gross semi-monthly) less all applicable payroll deductions and withholdings. The Company will also reimburse you, in accordance with its standard practices, for any expenses incurred in the performance of your post-Transition Date duties and responsibilities. The term of your post-Transition Date employment will be for a period (the “Transition Period”) commencing on the Transition Date and ending on the “Transition Ending Date” which shall be the date that is (a) six months after the Transition Date, (b) a later date determined by mutual agreement evidenced by an amendment to this Agreement or (c) if you become employed by any employer as described in Paragraph 8 before the six month anniversary of the Transition Date, the day before your employment with that other employer starts. A description of your duties and responsibilities during the Transition Period is set forth on Schedule 1. All duties and responsibilities assigned during the Transition Period may be conducted from your home office in San Diego, California.

SCHEDULE 1

3. Continued Vesting. As a result of your continuous service as an employee, all your stock options to purchase the Company’s Common Stock shall continue to vest until the Transition Ending Date. After the Transition Ending Date, in accordance with the your stock option agreements (the “Option Agreements”) and the stock option plans under which your options were granted (the “Option Plans”), you will have ninety (90) days to exercise your vested stock options, subject to certain exceptions as set forth in the Option Agreements and Option Plans. Upon the Transition Ending Date, all of your unvested stock options will terminate immediately.

4. Other Benefits. Until the Transition Ending Date, you will continue to be eligible to participate in the Company’s various benefit plans to which you are currently enrolled including medical, dental and vision insurance, as well as life, accidental death and disability insurance. You will receive 7 days of paid vacation during the Transition Period, in lieu of continuing to accrue vacation at your current rate, and will receive regular paid holidays. Until the Transition Ending Date, you will also continue to be eligible to participate in the Company’s 401(k) Plan, Section 529 College Savings Program and Employee Stock Purchase Plan.

5. Accrued Salary and Vacation. On the Transition Ending Date, the Company will pay you for all accrued salary and all accrued and unused vacation earned through the Transition Ending Date, subject to standard payroll deductions and withholdings. The Company will also pay you for any approved expenses incurred but not yet paid as of the Transition Ending Date. You are entitled to these payments by law.

6. Transition Ending Date Benefits. If you: (a) timely sign and date this Agreement, (b) allow it to become effective and fully perform under its terms, (c) sign and date the Transition Ending Date Release attached hereto as Exhibit A on or within 21 days after the Transition Ending Date, and (d) allow the Transition Ending Date Release to become effective and do not revoke it; then after your Transition Ending Date, the Company will pay you (i) $26,000, and (ii) $20,000 for each full month remaining from the Transition Ending Date until the 6 month anniversary of the Transition Date (collectively, the “Transition Ending Date Benefits”).

7. Proprietary Information and Inventions. You agree that the Proprietary Information and Inventions Agreement between you and the Company (the “Proprietary Information Agreement” shall remain in full force and effect following the date of this Agreement and the Transition Ending Date in accordance with its terms.

8. Other Work Activities. You have no duty to mitigate any compensation you receive from this Agreement. Throughout the Transition Period, you may engage in employment, consulting, or other work relationships in addition to your work for the Company, provided that such other employment, consulting, or work relationships do not interfere with your continuing obligations to the Company or otherwise create a conflict of interest with the Company. The Company will make reasonable arrangements to enable you to perform your work for the Company at such times and in such a manner so that it will not interfere with other activities in which you may engage. Notwithstanding the foregoing, in the event you are employed by a third party for more than an average of 20 hours per week, you agree to notify the Company. If this re-employment occurs, then your Transition Ending Date shall be the day before that employment starts. In order to protect the trade secrets and confidential and proprietary information of the Company, you agree that, during the Transition Period, you will notify the Company, in writing, before you obtain competitive employment, perform competitive work for any business entity, or engage in any other work activity that is or may be competitive with the Company, and you will

obtain the Company’s written consent before engaging in any such competitive activity. If you engage in such competitive activity without the Company’s prior written consent, or otherwise breach this Agreement or the Proprietary Information Agreement, then, in addition to any other remedies, the Company’s obligation to pay your salary will cease, and the Company will have the right to set your Transition Ending Date as of the date you first engaged in competitive activity and void your right to the Transition Ending Date Benefits described in Paragraph 6.

9. Other Compensation or Benefits.

(a) General Compensation or Benefits. You acknowledge that, except as expressly provided in this Agreement or unless your Transition Ending Date is extended beyond the date that the Board of Directors authorizes payments of incentive compensation to other Questcor executives, you are not entitled to receive and will not receive from the Company any additional compensation or benefits, including but not limited to salary, bonuses, severance, or employee benefits either during your continued employment or after the Transition Ending Date. By way of example, but not limitation, you acknowledge and agree that you are not eligible for any bonus compensation for 2008, and upon the termination of your employment on the Transition Ending Date, you will not be entitled to receive any severance pay notwithstanding the terms of that certain Severance Agreement between you and the Company dated September 28, 2005, which agreement is hereby terminated and of no further force or effect, and you hereby waive any right to any compensation or benefits under that Agreement.

(b) Change in Control Compensation or Benefits.

(i) Change in Control Benefits Prior to the Reassignment Date. From the date of this Agreement up until and including your Transition Date, you shall be entitled to receive any Change in Control benefits to which you become entitled during such period pursuant to the terms of your Change in Control Agreement dated September 28, 2005 and amended February 13, 2007 (“Change in Control Agreement”); provided, however, that if any such compensation or benefits are provided to you, they shall be in lieu of the other benefits provided under this Agreement, including without limitation any of the compensation or benefits set forth in Sections 2, 3, 4, 5 and 6 herein.

(ii) Change in Control Benefits After the Reassignment Date. After the Transition Date, you shall not be entitled to receive any Change in Control severance benefits, regardless of whether the Company is subject to a Change in Control after the Transition Date (including any Change in Control that occurs during the Transition Period) under your Change in Control Agreement. The acceleration of the vesting of your stock options upon a Change in Control shall be governed by the Option Plans and your Option Agreements. You expressly agree that your Change in Control Agreement shall have no further force or effect after the Transition Date, and you hereby waive any right to any compensation or benefits under that Agreement after the Transition Date. For purposes of clarification, if there is a Change of Control after the Transition Period, all other terms of this Agreement will remain in full effect.

10. Return of Company Property. You agree to return to the Company, on the Transition Ending Date or earlier if requested by the Company, all Company documents (and all copies thereof) and other property of the Company in your possession or control. You agree that you will make a diligent and timely search to locate any such documents, property and information. In addition, if you have used any personally owned computer, server, or e-mail system to receive,

store, review, prepare or transmit any Company confidential or proprietary data, materials or information, then you agree to provide the Company, no later than the Transition Ending Date, with a computer-useable copy of all such information and then permanently delete and expunge such Company confidential or proprietary information from those systems without retaining any reproductions (in whole or in part); and you agree to provide the Company access to your system as requested to verify that the necessary copying and/or deletion is done. Your timely compliance with this Section 10 is a precondition to your eligibility for the Transition Ending Date Benefits.

11. Nonsolicitation. In order to protect the trade secrets and confidential and proprietary information of the Company, you agree that during your continued employment, and for one year following the Transition Ending Date, you will not, either directly or through others, solicit or attempt to solicit any employee, consultant, or independent contractor of the Company to terminate his or her relationship with the Company in order to become an employee, consultant or independent contractor to or for any other person or entity.

12. Nondisparagement. You agree not to disparage the Company or the Company’s officers, directors, employees, shareholders, parents, subsidiaries, affiliates, and agents, in any manner likely to be harmful to them or their business, business reputation or personal reputation and the Company agrees not to disparage you in any manner likely to be harmful to your business, business reputation or personal reputation; provided that the parties may respond accurately and fully to any question, inquiry or request for information when required by legal process.

13. Release.

(a) General Release.

It may not be modified except in a written agreement approved by the Board and signed by you and a duly authorized officer of the Company. Each

party has carefully read this Agreement, has been afforded the opportunity to be advised of its meaning and consequences by his or its respective attorneys, and signed the same of his or its own free will. Any ambiguity in this Agreement shall not be construed against either party as the drafter.

The parties agree that venue for any legal action relating to this Agreement will be Alameda County, California.

19. Severability; Waiver of Breach. If any provision of this Agreement is determined to be invalid or unenforceable, in whole or in part, this determination will not affect any other provision of this Agreement and the provision in question shall be deemed modified so as to be rendered enforceable in a manner consistent with the intent of the parties, insofar as possible under applicable law. Any waiver of a breach of this Agreement, or rights hereunder, shall be in writing and shall not be deemed to be a waiver of any successive breach or rights hereunder.

20. Counterparts. This Agreement may be executed in two counterparts, each of which will be deemed an original, all of which together constitutes one and the same instrument. Facsimile signatures are as effective as original signatures.
