   &lt;/div&gt;
   &lt;div align="left" style="font-size: 10pt; margin-top: 6pt;  text-indent: 4%"&gt;On May&amp;#160;26, 2010, we entered into a Credit and Guaranty Agreement (the &amp;#8220;Credit Agreement&amp;#8221;) with
   Goldman Sachs Credit Partners L.P. and Goldman Sachs Bank USA, which provides for a single $30.0
   million senior secured term loan (the &amp;#8220;Senior Secured Term Loan&amp;#8221;). The Senior Secured Term Loan
   initially bears interest at an annual rate equal to the Base Rate, as defined in the Credit
   Agreement, plus 1.75%, or at our option, at an annual rate equal to LIBOR, plus 2.75% (3.17% as of
   June&amp;#160;30, 2010). The Senior Secured Term Loan, together with accrued interest, is due on December&amp;#160;1,
   2010.
   &lt;/div&gt;
   &lt;div align="left" style="font-size: 10pt; margin-top: 6pt;  text-indent: 4%"&gt;The Credit Agreement limits our ability, and the ability of certain subsidiaries, to: incur or
   guarantee indebtedness or certain liens or enter into negative pledges; pay dividends, repurchase
   stock or make certain other restricted payments or subsidiary distributions; enter into
   transactions with affiliates; consummate asset sales, acquisitions or mergers, sales and leasebacks
   or dispositions of subsidiary interests; prepay other indebtedness or
   make investments. In July 2010, we obtained a consent waiver from Goldman Sachs that will
   allow us to pay the outstanding principal amount of the 3.0% Notes due August 16, 2010.
   &lt;/div&gt;
   &lt;div align="left" style="font-size: 10pt; margin-top: 6pt;  text-indent: 4%"&gt;In connection with the Credit Agreement, we entered into a Pledge and Security Agreement that
   provides the lender a security interest in and continuing lien on certain of our assets until
   payment in full of the Senior Secured Term Loan. The Senior Secured Term Loan is guaranteed by
   certain of our subsidiaries that are presently guarantors of the 7.625% Senior Notes and the 8.375%
   Senior Notes (each as defined below).
   &lt;/div&gt;
   &lt;div align="left" style="font-size: 10pt; margin-top: 6pt;  text-indent: 4%"&gt;We expect that the Senior Secured Term Loan will be refinanced pursuant to the Commitment
   Letter (as defined in Note 20).

   &lt;div align="left" style="font-size: 10pt; margin-top: 6pt;  text-indent: 4%"&gt;On April&amp;#160;9, 2010, we issued $400.0&amp;#160;million aggregate principal amount of senior notes (the
   &amp;#8220;7.625% Senior Notes&amp;#8221;), at par, which bear a coupon interest rate of 7.625% and are due March&amp;#160;15,
   2020. Interest is payable in arrears semi-annually on each March&amp;#160;15 and September&amp;#160;15. The 7.625%
   Notes are guaranteed on a senior unsecured basis by certain of our subsidiaries, which are
   initially the same subsidiaries that guarantee our 8.375% Senior Notes (as defined below) and rank
   equally in right of payment with all of our existing and future unsecured and unsubordinated
   indebtedness and senior to our existing and future indebtedness that expressly provides for
   subordination to the 7.625% Senior Notes. The 7.625% Senior Notes are effectively junior in right
   of payment to our existing and future secured indebtedness, to the extent of the assets securing
   such indebtedness. The 7.625% Senior Notes were sold in accordance with Rule&amp;#160;144A and Regulation&amp;#160;S
   of the Securities Act and we are obligated (i)&amp;#160;to file a registration statement with the SEC that
   would enable the holders of the 7.625% Senior Notes to exchange them
   for publicly registered notes having substantially the same terms and (ii)&amp;#160;to complete such
   exchange offer within 365&amp;#160;days of April&amp;#160;9, 2010.
   &lt;/div&gt;
   &lt;div align="left" style="font-size: 10pt; margin-top: 6pt;  text-indent: 4%"&gt;We may redeem some or all of the 7.625% Senior Notes at any time prior to March&amp;#160;15, 2015 by
   paying a redemption price equal to the principal amount of the 7.625% Senior Notes, plus the
   Applicable Premium (as defined in the indenture as discussed below), plus accrued and unpaid
   interest, if any, to the redemption date. At any time prior to March&amp;#160;15, 2013, we may use the net
   cash proceeds of certain equity offerings of our capital stock to redeem up to 35% of the principal
   amount of the 7.625% Senior Notes at a redemption price equal to 107.625% of their principal amount
   plus accrued and unpaid interest, plus certain additional interest as specified in the indenture,
   if any, to the redemption date; provided that at least 65% of the aggregate principal amount of
   notes issued under the indenture remain outstanding immediately after such redemption and the
   redemption occurs within 90&amp;#160;days after the closing of such equity offering. At any time on or after
   March&amp;#160;15, 2015, we may redeem some or all of the 7.625% Senior Notes by paying a redemption price
   expressed as a percentage of the principal amount (103.813% if redeemed during the twelve-month
   period beginning on March&amp;#160;15, 2015, 102.542% if redeemed during the twelve-month period beginning
   on March&amp;#160;15, 2016, 101.271% if redeemed during the twelve-month period beginning on March&amp;#160;15, 2017
   and 100% if redeemed on or after March&amp;#160;15, 2018), plus accrued and unpaid interest, plus certain
   liquidated damages as specified in the indenture, if any, to the redemption date.
   &lt;/div&gt;
   &lt;div align="left" style="font-size: 10pt; margin-top: 6pt;  text-indent: 4%"&gt;If
   we experience a change of control (as defined in the indenture governing the 7.625% Senior Notes), we may be required to offer to purchase the 7.625%
   Senior Notes at a purchase price equal to 101% of the principal amount, plus accrued and unpaid
   interest, plus certain liquidated damages as specified in the indenture, if any, to but excluding
   the repurchase date.
   &lt;/div&gt;
   &lt;div align="left" style="font-size: 10pt; margin-top: 6pt;  text-indent: 4%"&gt;The indenture governing the 7.625% Senior Notes contains covenants that will limit our ability
   and the ability of our restricted subsidiaries to, among other things: incur additional debt; pay
   dividends or make other distributions, repurchase capital stock, repurchase subordinated debt and
   make certain investments; create liens; create restrictions on the payment of dividends and other
   amounts to us from restricted subsidiaries; sell assets or merge or consolidate with or into other
   companies; and engage in transactions with affiliates. If an event of default, as specified in the
   indenture governing the 7.625% Senior Notes, shall occur and be continuing, either the trustee or
   the holders of a specified percentage of the 7.625% Senior Notes may accelerate the maturity of all
   the 7.625% Senior Notes. As of June&amp;#160;30, 2010, we were in compliance with these covenants.
   &lt;/div&gt;
   &lt;div align="left" style="font-size: 10pt; margin-top: 6pt;  text-indent: 4%"&gt;We expect that the 7.625% Senior Notes will be refinanced pursuant to the Commitment Letter

   &lt;/div&gt;
   &lt;div align="left" style="font-size: 10pt; margin-top: 6pt;  text-indent: 4%"&gt;In June&amp;#160;2009, we issued $365.0&amp;#160;million aggregate principal amount of senior notes (the &amp;#8220;8.375%
   Senior Notes&amp;#8221;), which bear a coupon interest rate of 8.375% and are due June&amp;#160;15, 2016. The 8.375%
   Senior Notes were issued at a discounted price of 96.797%, resulting in an effective annual yield
   of 9.0%. Interest is payable in arrears semi-annually on each June&amp;#160;15 and December&amp;#160;15. The 8.375%
   Senior Notes are guaranteed on a senior unsecured basis by certain of our subsidiaries. If we
   experience a change of control, we may be required to offer to purchase the 8.375% Senior Notes at
   a purchase price equal to 101% of the principal amount, plus accrued and unpaid interest, plus
   liquidated damages, if any, to the redemption date. The indenture governing the 8.375% Senior Notes
   contains covenants that will limit our ability and the ability of our restricted subsidiaries to,
   among other things: incur
   additional debt; pay dividends or make other distributions; repurchase
   capital stock; repurchase subordinated debt and make certain investments; create liens; create
   restrictions on the payment of dividends and other amounts to us from restricted subsidiaries; sell
   assets or merge or consolidate with or into other companies; and engage in transactions with
   affiliates. As of June&amp;#160;30, 2010, we were in compliance with these covenants.
   &lt;/div&gt;
   &lt;div align="left" style="font-size: 10pt; margin-top: 6pt;  text-indent: 4%"&gt;The 8.375% Senior Notes were sold in accordance with Rule&amp;#160;144A of the Securities Act and
   Regulation&amp;#160;S of the Securities Act. On March&amp;#160;5, 2010, we filed a registration statement on Form
   S-4, which was declared effective on March&amp;#160;29, 2010. The registration statement registered the
   exchange of the 8.375% Senior Notes for publicly registered notes with substantially the same
   terms. The exchange offer for the 8.375% Senior Notes commenced on
   March&amp;#160;30, 2010 and expired on April&amp;#160;28, 2010. In May&amp;#160;2010, the 8.375% Senior Notes were
   exchanged for publicly registered notes with substantially the same terms.
   &lt;/div&gt;
   &lt;div align="left" style="font-size: 10pt; margin-top: 6pt;  text-indent: 4%"&gt;We expect that the 8.375% Senior Notes will be refinanced pursuant to the Commitment Letter

   &lt;/div&gt;
   &lt;div align="left" style="font-size: 10pt; margin-top: 6pt;  text-indent: 4%"&gt;In November&amp;#160;2003, we issued $240.0&amp;#160;million aggregate principal amount of 3.0% Convertible
   Subordinated Notes due August&amp;#160;2010 (the &amp;#8220;3.0% Notes&amp;#8221;) and $240.0&amp;#160;million aggregate principal amount
   of 4.0% Convertible Subordinated Notes due 2013 (the &amp;#8220;4.0% Notes&amp;#8221;), which were issued as two series
   of notes under a single indenture. Interest on the 3.0% Notes is payable semi-annually on February
   16 and August&amp;#160;16 of each year. Interest on the 4.0% Notes is payable semi-annually on May&amp;#160;15 and
   November&amp;#160;15 of each year. We have the right to redeem the 4.0% Notes, in whole or in part, at their
   principal amount on or after May&amp;#160;20, 2011. The 3.0% Notes and 4.0% Notes are convertible into our
   common stock at an initial conversion rate of 31.6336 shares per $1,000 principal amount of notes,
   subject to adjustment. Upon conversion, we will have the right to satisfy the conversion
   obligations by delivery, at our option in shares of our common stock, in cash or in a combination
   thereof. It is our intent to settle the principal amount of the 3.0% Notes and 4.0% Notes in cash.
   In July&amp;#160;2010, pursuant to the indenture, we notified the trustee of our election to settle the
   principal amount of the 3.0% Notes in cash, and to settle the remainder of the conversion
   obligation in shares of our common stock. The 3.0% Notes and 4.0% Notes are subordinated unsecured
   obligations, ranking in right of payment behind our senior debt, if any. As of June&amp;#160;30, 2010, $48.9
   million aggregate principal amount of 3.0% Notes and $225.0&amp;#160;million aggregate principal amount of
   4.0% Notes were outstanding.
   &lt;/div&gt;
   &lt;div align="left" style="font-size: 10pt; margin-top: 6pt;  text-indent: 4%"&gt;During the six months ended June&amp;#160;30, 2009, we purchased an aggregate of $117.6&amp;#160;million
   principal amount of the 3.0% Notes and 4.0% Notes at a purchase price of $115.2&amp;#160;million. The
   carrying amount of the 3.0% Notes and 4.0% Notes purchased was $109.2&amp;#160;million and the estimated
   fair value of the Notes exclusive of the conversion feature was $101.8&amp;#160;million. The difference
   between the carrying amount and the estimated fair value was recognized as a gain of $7.4&amp;#160;million
   upon early extinguishment of debt. The difference between the estimated fair value of $101.8
   million and the purchase price of $115.2&amp;#160;million was $13.4&amp;#160;million and was charged to additional
   capital. A portion of the purchase price was attributable to accreted interest on the debt discount
   and deferred loan costs and is presented in the statement of cash flows for the six months ended
   June&amp;#160;30, 2009 as payments of accreted interest on long-term debt in cash flow from operating
   activities in continuing operations.
   &lt;/div&gt;
   &lt;div align="left" style="font-size: 10pt; margin-top: 6pt;  text-indent: 4%"&gt;In connection with the offering of the 3.0% Notes and the 4.0% Notes, we entered into
   convertible note hedge and written call option transactions with respect to our common stock (the
   &amp;#8220;Convertible Note Hedge&amp;#8221;). The Convertible Note Hedge consisted of our purchasing call options on
   12,653,440 shares of our common stock at a strike price of $31.61 and selling call options on the
   identical number of shares at $39.52. The number of shares covered by the Convertible Note Hedge is
   the same number of shares underlying the conversion of $200.0&amp;#160;million principal amount of the 3.0%
   Notes and $200.0&amp;#160;million principal amount of the 4.0% Notes. The Convertible Note Hedge is expected
   to reduce the potential dilution from conversion of the 3.0% Notes and the 4.0% Notes. The written
   call options offset, to some extent, the cost of the call options purchased. As a result of the
   cessation of Valeant&amp;#8217;s common dividend, the strike price on the purchased call options were
   adjusted during 2007, with the new strike prices becoming $34.61 and $35.36 for the 3.0% Notes and

   Notes, we also effected a proportionate partial termination of the Convertible Note Hedge, reducing
   the number of shares covered by the Convertible Note Hedge by 4,780,913 shares. As of June&amp;#160;30, 2010
   and December&amp;#160;31, 2009, the number of shares covered by the Convertible Note Hedge was 7,872,527,
   the same number of shares underlying the conversion of the remaining balance of $48.9&amp;#160;million
   principal amount of the 3.0% Notes and $200.0&amp;#160;million principal amount of the 4.0% Notes.
