   &lt;div align="justify" style="font-size: 10pt; margin-top: 10pt"&gt;&lt;b&gt;3. Acquisition of Gloucester Pharmaceuticals, Inc.&lt;/b&gt;
   &lt;/div&gt;
   &lt;div align="justify" style="font-size: 10pt; margin-top: 10pt"&gt;On January&amp;#160;15, 2010, the Company acquired all of the outstanding common stock and stock options of
   Gloucester in a transaction accounted for under the acquisition method of accounting for business
   combinations, ASC No.&amp;#160;805, &amp;#8220;Business Combinations,&amp;#8221; or ASC 805. Under the acquisition method of
   accounting, the assets acquired and liabilities assumed of Gloucester were recorded as of the
   acquisition date, at their respective fair values, and consolidated with those of the Company. The
   reported consolidated
   financial condition and results of operations of the Company after completion of the acquisition
   reflect these fair values. Gloucester&amp;#8217;s results of operations are included in the Company&amp;#8217;s
   consolidated financial statements from the date of acquisition. Gloucester&amp;#8217;s results of operations
   prior to the acquisition were determined to be immaterial to the Company; therefore, proforma
   financial statements are not required to be presented.

   &lt;/b&gt;
   &lt;/div&gt;
   &lt;div align="justify" style="font-size: 10pt; margin-top: 10pt"&gt;The Company paid $338.9&amp;#160;million in cash before milestone payments and may make additional
   future payments of $300.0&amp;#160;million in contingent regulatory milestone payments. Prior to the
   acquisition, Gloucester was a privately held biopharmaceutical company that acquired clinical-stage
   oncology drug candidates with the goal of advancing them through regulatory approval and
   commercialization. The Company acquired Gloucester to enhance its portfolio of therapies for
   patients with life-threatening illnesses worldwide.
   &lt;/div&gt;
   &lt;div align="justify" style="font-size: 10pt; margin-top: 10pt"&gt;The purchase price allocation resulted in the following amounts being allocated to the assets
   acquired and liabilities assumed at the acquisition date based upon their respective fair values

   &lt;div align="justify" style="font-size: 10pt; margin-top: 10pt"&gt;Asset categories acquired in the Gloucester acquisition included working capital, inventory, fixed
   assets, developed product right assets and in-process research and development, or IPR&amp;#038;D, product
   right assets. Fair values of working capital and fixed assets were determined to approximate book
   values while the fair value of inventory was determined to be greater than book value.
   &lt;/div&gt;
   &lt;div align="justify" style="font-size: 10pt; margin-top: 10pt"&gt;The fair value of developed product right assets was based on expected cash flows from developed
   product right sales of ISTODAX&lt;sup style="font-size: 85%; vertical-align: text-top"&gt;&amp;#174;&lt;/sup&gt; (romidepsin), a novel histone deacetylase (HDAC)
   inhibitor, which was approved for marketing in the United States in November&amp;#160;2009 by the FDA for
   the treatment of cutaneous T-cell lymphoma, or CTCL, in patients who have received at least one
   prior systemic therapy. Prior to the acquisition, Gloucester was also conducting a registration
   trial in peripheral T-cell lymphoma, or PTCL, in the United States with an anticipated supplemental
   New Drug Application filing in 2010 for this indication. Fair values were derived using
   probability-weighted cash flows. The U.S. CTCL developed product right asset is being amortized
   over its economic useful life of ten years. The compassionate use right asset is being amortized
   evenly over the asset&amp;#8217;s economic useful life of 1.5&amp;#160;years.
   &lt;/div&gt;
   &lt;div align="justify" style="font-size: 10pt; margin-top: 10pt"&gt;The fair value of IPR&amp;#038;D product right assets was based on expected cash flows from sales of
   ISTODAX&lt;sup style="font-size: 85%; vertical-align: text-top"&gt;&amp;#174;&lt;/sup&gt; (romidepsin)&amp;#160;for the treatment of PTCL, which had not yet achieved regulatory
   approval for marketing and has no future alternative use. The $349.0&amp;#160;million estimated fair value
   of IPR&amp;#038;D product rights was derived using probability-weighted cash flows. The fair value was
   based on expected cash flows from the treatment of PTCL in the United States and PTCL in the
   European Union, or E.U., based on key assumptions such as estimates of sales and operating profits
   related to the programs considering their stages of development; the time and resources needed to
   complete the regulatory approval process for the products and the life of the potential
   commercialized products and associated risks, including the inherent difficulties and uncertainties
   in obtaining regulatory approvals.

   &lt;div align="justify" style="font-size: 10pt; margin-top: 10pt"&gt;The U.S. PTCL IPR&amp;#038;D product right asset was assigned a value of $287.0&amp;#160;million based on related
   future net cash flows estimated using a risk-adjusted discount rate of 14.5% and an anticipated
   regulatory approval date in mid-2011 with market exclusivity rights expected to continue through
   2017. The E.U. PTCL IPR&amp;#038;D product right asset was assigned a value of $62.0&amp;#160;million based on
   future net cash flows using a risk-adjusted discount rate of 14.5% and an anticipated regulatory
   approval date in mid-2015 with market exclusivity rights expected to continue through 2021.
   &lt;/div&gt;
   &lt;div align="justify" style="font-size: 10pt; margin-top: 10pt"&gt;The excess of purchase price over the fair value amounts assigned to the assets acquired and
   liabilities assumed represents the goodwill amount resulting from the acquisition. The Company
   does not expect any portion of this goodwill to be deductible for tax purposes. The goodwill
   attributable to the Company&amp;#8217;s acquisition of Gloucester has been recorded as a noncurrent asset in
   its Consolidated Balance Sheets and is not amortized, but is subject to review for impairment in
   accordance with ASC 350, &amp;#8220;Goodwill and Other Intangible Assets.&amp;#8221;
   &lt;/div&gt;
   &lt;div align="justify" style="font-size: 10pt; margin-top: 10pt"&gt;The Company accounts for contingent consideration in accordance with applicable guidance provided
   within the business combination rules of ASC 805. As part of the Company&amp;#8217;s consideration for the
   Gloucester acquisition, it is contractually obligated to pay certain consideration resulting from
   the outcome of future events. The Company updates its assumptions each reporting period based on
   new developments and records such amounts at fair value until such consideration is satisfied.
   &lt;/div&gt;
   &lt;div align="justify" style="font-size: 10pt; margin-top: 10pt"&gt;The Gloucester acquisition included two contingent considerations which would obligate the Company
   to make a $180.0&amp;#160;million cash milestone payment to the former Gloucester shareholders upon the
   marketing approval for the U.S. PTCL IPR&amp;#038;D product right asset and a $120.0&amp;#160;million cash milestone
   payment upon the marketing approval for the E.U. PTCL IPR&amp;#038;D product right asset.
   &lt;/div&gt;
   &lt;div align="justify" style="font-size: 10pt; margin-top: 10pt"&gt;The initial fair value of contingent considerations was $230.2&amp;#160;million, consisting of $156.7
   million based on the $180.0&amp;#160;million milestone payment upon U.S. PTCL approval and $73.5&amp;#160;million
   based on the $120.0&amp;#160;million milestone payment upon E.U. PTCL approval. The Company determined the
   fair value of these obligations to pay additional milestone payments upon approvals based on a
   probability-weighted income approach. This fair value measurement is based on significant input
   not observable in the market and thus represents a Level 3 measurement within the fair value
   hierarchy. The resulting probability-weighted cash flows were discounted using a Baa rated debt
   yield of 6.15&amp;#160;percent, which the Company believes is appropriate and representative of a market
   participant assumption. The range of estimated milestone payments is from no payment if both
   product indications fail to gain market approval to $300.0&amp;#160;million if both product indications gain
   market approval. The Company classified the contingent considerations as liabilities, which were
   measured at fair value as of the acquisition date. Fair value is based on the future milestone
   payments adjusted for the probability of each payment and the time until each payment is expected
   to be made.
   &lt;/div&gt;
   &lt;div align="justify" style="font-size: 10pt; margin-top: 10pt"&gt;Subsequent to the acquisition date, the Company has measured the contingent consideration
   arrangement at fair value each period with changes in fair value recognized in operating earnings.
   Changes pertaining to facts and circumstances that existed as of the acquisition date will be
   recognized as adjustments to goodwill. Changes in fair values reflect new information about the
   IPR&amp;#038;D assets and the passage of time. In the absence of new information, changes in fair value
   will only reflect the passage of time as development work towards the achievement of the milestones
   progresses and will be accrued based on an accretion schedule. At September&amp;#160;30, 2010, the balance
   of the contingent consideration was $246.9&amp;#160;million, of which $167.8&amp;#160;million is included in other
   current liabilities and $79.1&amp;#160;million included in other non-current liabilities.
