</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">Dear Mr.&nbsp;Halladay:
</DIV>


<DIV align="left" style="font-size: 10pt; margin-top: 6pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;This letter (this &#147;Amendment&#148;) amends that certain Change-in-Control Agreement (the &#147;Original
Agreement&#148;) entered into by and between you and Questcor Pharmaceuticals, Inc., a California
corporation (&#147;Questcor&#148;) in connection with your commencement of employment at Questcor. Unless
otherwise modified by this Amendment, the Original Agreement remains in full force and effect.
</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;This Amendment, once fully executed and delivered by Questcor and you, entitles you to receive
the benefits set forth in this Amendment in the event of certain Changes in Control (as defined in
The Questcor Pharmaceuticals Incorporated 1992 Stock Option Plan (the &#147;1992 Plan) or the 2006
Equity Incentive Award Plan (the &#147;2006 Plan&#148;). You shall receive no benefits under this Amendment
unless there has been a Change in Control.
</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;1.&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; <U>Cash Severance</U>. In the event that a Change in Control occurs, and your employment
with the Company is terminated as a result of an Involuntary Termination (as defined below) at any
time within the twelve (12)&nbsp;month period commencing on the date of such Change in Control, you will
receive severance compensation equal to the sum of (i)&nbsp;an amount equal to the product of your
minimum annual base salary in effect as of the date of termination multiplied by the number one
(1), plus (ii)&nbsp;an amount equal to the product of your target bonus as established by the Board of
Directors or its Compensation Committee for the year during which the termination takes place
multiplied by the number one (1) (the &#147;Severance Payment&#148;). If payment is due to you as a result
of you terminating your employment for Good Reason, then the Severance Payment shall be paid as
follows: (1)&nbsp;if, on the date you terminate your employment for Good Reason, the Company is a
reporting company under the Securities Exchange Act of 1934 (the &#147;Exchange Act&#148;), then you will be
entitled to receive such payment in a single lump sum on the first business day that occurs at the
end of the period commencing on the date of termination and ending six months after the last day of
the calendar month in which the date of termination occurs (e.g., if you terminate your employment
on March&nbsp;15, 2007, the Company will pay the amount specified herein on the first business day
immediately following September&nbsp;30, 2007); (2)&nbsp;however, if the Company is not a reporting company
under the Exchange Act at the time you terminate your employment for Good Reason, you shall be
entitled to receive such payment in a single lump sum on the fifth business day following your
termination of employment. If paid upon a Change in Control, the Severance Payment shall be in
lieu of, and not in addition to, the payment of any cash severance payments that you may otherwise
be entitled to under your Offer Letter.
