Re: Offer of Employment

Dear Mr. Beers:

Questcor Pharmaceuticals, Inc. (the "Company") is pleased to offer you the
position of Vice President, Marketing, a corporate officer, on the terms
described below. Should you accept our offer of employment, your start date will
be September 15, 2003.

You will report to Charles J. Casamento, Chief Executive Officer. Your office
will be located at our facility in Union City, California. Of course, the
Company may change your reporting responsibilities, position, duties, and work
location from time to time, as it deems necessary.

Your base compensation will be $184,000 per annum ($7,666.66 semi-monthly) less
all amounts the Company is required to hold under applicable laws. Effective
January 1, 2004, you will be a participant in the annual management incentive
program for executives, which has been approved by the Compensation Committee.
Your incentive bonus will be based on the attainment of specific milestones
during each calendar year. The milestones will be communicated to you in writing
by Mr. Casamento following the start of your employment and will be updated
annually as part of the performance review process. Your maximum bonus
opportunity will be 33% of your base compensation earnings in the calendar year
to which it applies. The Company will provide you a relocation allowance of an
amount not to exceed $75,000, to cover all reasonable and customary expenses
associated with your relocation to the San Francisco Bay area. Those expenses
paid by you which affect your income tax liability will be "grossed-up"
accordingly. In addition, as soon as administratively practicable following the
start of your employment, the Company will provide you with a change of control
agreement commensurate with your position.

You will be eligible to participate in the Company's various benefit plans
including medical, dental and vision insurance, as well as life, accidental
death and disability insurance. You will receive 16 days of  paid vacation per
calendar year, in addition to 12 paid regular holidays and two paid floating
holidays. You will also be eligible to participate in the Company's 401(k) Plan,
Section 529 College Savings Program and Employee Stock Purchase Plan. The
eligibility requirements for these plans are explained in the Company's Employee
Handbook, and in the case of the Company's 401(k) Plan, in the 401(k) Plan's
summary plan description. A copy of the Employee Handbook and the
<PAGE>
401(k) Plan's summary plan description will be provided to you. Please read
them carefully. Of course, to the extent the provisions of the various plans
are inconsistent with the provisions of the Employee Handbook or summary plan
description, the plan provisions will control.

As you no doubt appreciate, as a Company employee, you will be expected to
abide by Company rules and regulations, acknowledge in writing that you have
read the Company's Employee Handbook, sign and comply with a Proprietary
Information and Inventions Agreement which prohibits unauthorized use or
disclosure of Company proprietary information and sign the Policy Against
Insider Trading.

The Company's management has in effect an employee stock option plan to
recognize the talent and skills our employees bring to the Company. Management
will recommend to the Board of Directors that, at the time you join the
Company, the Company grant to you an option under the stock option plan to
purchase 300,000 shares of the Common Stock of the Company at an exercise price
equal to 100% of the closing price of the Company's Common Stock on the date
prior to approval by the Board of Directors. One-eighth (1/8th) of these
options will vest after six (6) months of employment and thereafter the
remaining shares will vest at the rate of 1/48th of the total grant on each
monthly anniversary of your continued employment with the Company. The option
will be subject to the terms and conditions of the Company's stock option plan
and your stock option agreement.

The Company will review your performance in accordance with the Employee
Handbook, to assess your accomplishment of milestones and goals, which the
Company reasonably sets for you. The Company will consider whether and when you
should receive increases in your compensation and benefits as described therein
based on such accomplishments.

You may terminate your employment with the Company at any time and for any
reason whatsoever simply by notifying the Company. Likewise, the Company may
terminate your employment at any time and for any reason whatsoever, with or
without cause or advance notice. This at-will employment relationship cannot be
changed except in writing signed by the Chief Executive Officer or the Chief
Financial Officer.

Any and all disputes connected with, relating to or arising from your
employment with the Company will be settled by final and binding arbitration in
accordance with the rules of the American Arbitration Association as presently
in force. The only claims not covered by this Agreement are claims for benefits
under the unemployment insurance or workers' compensation laws. Any such
arbitration will take place in Alameda County, California. The parties hereby
incorporate into this agreement all of the arbitration provisions of Section
1283.05 of the California Code of Civil Procedure. The Company understands and
agrees that it will bear the costs of the arbitration filing and hearing fees
and the cost of the arbitrator. Each side will bear its own attorneys' fees,
and the arbitrator will not have authority to award attorneys' fees unless a
statutory section at issue in the dispute authorizes the award of attorneys'
fees to the prevailing party, in which case the arbitrator has authority to
make such award as permitted by the statute in question. The arbitration shall
be instead of any civil litigation; this means that you are waiving any right
to a jury trial, and that the arbitrator's

                                       2.
<PAGE>
decision shall be final and binding to the fullest extent permitted by law and
enforceable by any court having jurisdiction thereof. Judgment upon any award
rendered by the arbitrators may be entered in any court having jurisdiction.

The employment terms in this letter supersede any other agreements or promises
made to you by anyone, whether oral or written, express or implied. In the event
you accept this employment offer, the terms set forth in this letter will
comprise our final, complete and exclusive agreement with respect to the subject
matter of this letter. Thus, by accepting this employment offer and signing this
offer letter, you agree to be bound by its terms and conditions. As required
by law, the Company's offer is subject to satisfactory proof of your right to
work in the United States no later than three days after your employment begins.

Please sign and date this letter, and return it to me as soon as possible. This
offer terminates if it is not signed and delivered to me by September 2, 2003. A
facsimile copy will suffice for this purpose, so long as an original signature
is delivered when you commence employment. My confidential facsimile number is
(510) 400-0710.

We look forward to your favorable reply and to a productive and enjoyable work
relationship.

Sincerely,

/s/ Charles J. Casamento

Charles J. Casamento
Chairman, President and Chief Executive Officer

I hereby acknowledge that I have read the foregoing letter and agree to be
bound by all of its terms and conditions:
