   &lt;/div&gt;
   &lt;div align="justify" style="font-size: 10pt; margin-top: 10pt"&gt;&lt;b&gt;&lt;i&gt;Novartis Pharma AG: &lt;/i&gt;&lt;/b&gt;The Company entered into an agreement with Novartis in which the Company
   granted to Novartis an exclusive worldwide license (excluding Canada) to develop and market
   FOCALIN&lt;sup style="font-size: 85%; vertical-align: text-top"&gt;&amp;#174;&lt;/sup&gt; (d-methylphenidate, or d -MPH) and FOCALIN XR&lt;sup style="font-size: 85%; vertical-align: text-top"&gt;&amp;#174;&lt;/sup&gt;, the long-acting drug
   formulation for attention deficit disorder, or ADD, and attention deficit hyperactivity disorder,
   or ADHD. The Company also granted Novartis rights to all of its related intellectual property and
   patents, including formulations of the currently marketed RITALIN LA&lt;sup style="font-size: 85%; vertical-align: text-top"&gt;&amp;#174;&lt;/sup&gt;. Under the
   agreement, the Company is entitled to receive up to $100.0&amp;#160;million in upfront and regulatory
   achievement milestone payments. To date, the Company has received upfront and regulatory
   achievement milestone payments totaling $55.0&amp;#160;million. The Company also sells FOCALIN&lt;sup style="font-size: 85%; vertical-align: text-top"&gt;&amp;#174;&lt;/sup&gt;
   to Novartis and currently receives royalties of between 35% and 30% on sales of all of Novartis&amp;#8217;
   FOCALIN XR&lt;sup style="font-size: 85%; vertical-align: text-top"&gt;&amp;#174; &lt;/sup&gt;and RITALIN&lt;sup style="font-size: 85%; vertical-align: text-top"&gt;&amp;#174;&lt;/sup&gt; family of ADHD-related products.
   &lt;/div&gt;
   &lt;div align="justify" style="font-size: 10pt; margin-top: 10pt"&gt;The agreement will continue until the later of (i)&amp;#160;the tenth anniversary of the first commercial
   launch on a country-by-country basis or (ii)&amp;#160;when the last applicable patent expires with respect
   to that country. At the expiration date, the Company shall grant Novartis a perpetual,
   non-exclusive, royalty-free license to make, have made, use, import and sell d-MPH and
   Ritalin&lt;sup style="font-size: 85%; vertical-align: text-top"&gt;&amp;#174;&lt;/sup&gt; under its technology.
   &lt;/div&gt;
   &lt;div align="justify" style="font-size: 10pt; margin-top: 10pt"&gt;Prior to its expiration as described above, the agreement may be terminated by:

   &lt;div align="justify" style="font-size: 10pt; margin-top: 10pt"&gt;If the agreement is terminated by the Company then all licenses granted to Novartis under the
   agreement will terminate and Novartis will also grant the Company a non-exclusive license to

   &lt;div align="justify" style="font-size: 10pt; margin-top: 10pt"&gt;If the agreement is terminated by Novartis then all licenses granted to Novartis under the

   &lt;/div&gt;
   &lt;div align="justify" style="font-size: 10pt; margin-top: 10pt"&gt;If the agreement is terminated by Novartis because of a material breach by the Company, then
   Novartis can make a claim for damages against the Company and the Company shall grant Novartis a
   perpetual, non-exclusive, royalty-free license to make, have made, use, import and sell d-MPH and
   Ritalin&lt;sup style="font-size: 85%; vertical-align: text-top"&gt;&amp;#174;&lt;/sup&gt; under the Company&amp;#8217;s technology.

   &lt;div align="justify" style="font-size: 10pt; margin-top: 10pt"&gt;When generic versions of long-acting methylphenidate hydrochloride and dexmethylphenidate
   hydrochloride enter the market, the Company expects Novartis&amp;#8217; sales of Ritalin LA&lt;sup style="font-size: 85%; vertical-align: text-top"&gt;&amp;#174;&lt;/sup&gt; and
   Focalin XR&lt;sup style="font-size: 85%; vertical-align: text-top"&gt;&amp;#174;&lt;/sup&gt; products to decrease and therefore its royalties under this agreement to
   also decrease.
   &lt;/div&gt;
   &lt;div align="justify" style="font-size: 10pt; margin-top: 10pt"&gt;&lt;b&gt;&lt;i&gt;Array BioPharma Inc.: &lt;/i&gt;&lt;/b&gt;The Company has a research collaboration agreement with Array BioPharma
   Inc., or Array, focused on the discovery, development and commercialization of novel therapeutics
   in cancer and inflammation. As part of this agreement, the Company made an upfront payment in
   September&amp;#160;2007 to Array of $40.0&amp;#160;million, which was recorded as research and development expense,
   in return for an option to receive exclusive worldwide rights for compounds developed against two
   of the four research targets defined in the agreement, except for Array&amp;#8217;s limited U.S.
   co-promotional rights. In June&amp;#160;2009, the Company made an additional upfront payment of $4.5
   million to expand the research targets defined in the agreement, which was recorded as research and
   development expense. Array will be responsible for all discovery and clinical
   development through Phase I or Phase IIa and be entitled to receive, for each compound, potential
   milestone payments of approximately $200.0&amp;#160;million if certain discovery, development and regulatory
   milestones are achieved, and $300.0&amp;#160;million if certain commercial milestones are achieved as well
   as royalties on net sales.

   &lt;div align="justify" style="font-size: 10pt; margin-top: 10pt"&gt;The Company&amp;#8217;s option will terminate upon the earlier of either a termination of the agreement, the

   targets defined in the agreement, or September&amp;#160;21, 2012, unless the term is extended. The Company
   may unilaterally extend the option term for two additional one-year terms until September&amp;#160;21, 2014
   and the parties may mutually extend the term for two additional one-year terms until September&amp;#160;21,
   2016. Upon exercise of a Company option, the agreement will continue until the Company has
   satisfied all royalty payment obligations to Array. Upon the expiration of the agreement, Array
   will grant the Company a fully paid-up, royalty-free license to use certain intellectual property
   of Array to market and sell the compounds and products developed under the agreement. The

   &lt;div align="justify" style="font-size: 10pt; margin-top: 10pt"&gt;&lt;b&gt;&lt;i&gt;PTC Therapeutics, Inc.: &lt;/i&gt;&lt;/b&gt;In September&amp;#160;2007, the Company invested $20.0&amp;#160;million, of which $1.1
   million represented research and development expense, in Series&amp;#160;F-2 Convertible Preferred Stock of
   PTC Therapeutics, Inc., or PTC, and, in December&amp;#160;2009, the Company invested an additional $1.5
   million in Series&amp;#160;G Convertible Preferred Stock of PTC. In September&amp;#160;2007, the Company also entered
   into a separate research and option agreement whereby PTC would perform discovery research
   activities. Under the agreement, both parties could subsequently agree to advance research on
   certain discovery targets and enter into a separate pre-negotiated collaboration and license
   agreement which would replace the original research and option agreement.
   &lt;/div&gt;
   &lt;div align="justify" style="font-size: 10pt; margin-top: 10pt"&gt;On July&amp;#160;16, 2009, the Company and PTC agreed to advance research on one discovery target and
   entered into a pre-negotiated collaboration and license agreement under which PTC was eligible to
   receive quarterly research fees, as defined in the agreement, and was entitled to receive potential
   milestone payments of approximately $129.0&amp;#160;million if certain development, regulatory and
   sales-based milestones were achieved. The agreement also entitled PTC to receive tiered royalties
   on worldwide net sales. Under the agreement, the Company may transfer certain research and
   development activities from PTC to the Company and upon such transfer the Company will no longer
   fund such quarterly research fees to PTC.
   &lt;/div&gt;
   &lt;div align="justify" style="font-size: 10pt; margin-top: 10pt"&gt;The pre-negotiated collaboration and license agreement was terminated in August&amp;#160;2010 by the mutual
   agreement of the Company and PTC in accordance with the termination provisions in the agreement,
   ending the obligation of the Company to make payments under the agreement beyond any quarterly
   research fees already incurred.

   &lt;div align="justify" style="font-size: 10pt; margin-top: 10pt"&gt;The Company continues to hold investments in Series&amp;#160;F-2 Convertible Preferred Stock and Series&amp;#160;G

   Acceleron, for the joint development and commercialization of ACE-011, currently being studied for
   treatment of chemotherapy-induced anemia, metastatic bone disease and renal anemia. The
   collaboration combines both companies&amp;#8217; resources and commitment to developing products for the
   treatment of cancer and cancer-related bone loss. The agreement also includes an option for
   certain discovery stage programs. Under the terms of the agreement, the Company and Acceleron will
   jointly develop, manufacture and commercialize Acceleron&amp;#8217;s products for bone loss. The Company
   made an upfront payment to Acceleron in February&amp;#160;2008 of $50.0&amp;#160;million, which included a $5.0
   million equity investment in Acceleron, with the remainder recorded as research and development
   expense. In addition, in the event of an initial public offering of Acceleron, the Company will
   purchase a minimum of $7.0&amp;#160;million of Acceleron common stock.
   &lt;/div&gt;
   &lt;div align="justify" style="font-size: 10pt; margin-top: 10pt"&gt;Acceleron will retain responsibility for initial activities, including research and development,
   through the end of Phase IIa clinical trials, as well as manufacturing the clinical supplies for
   these studies. In turn, the Company will conduct the Phase IIb and Phase III clinical studies and
   will oversee the manufacture of Phase III and commercial supplies. Acceleron will pay a share of
   the development expenses and is eligible to receive development, regulatory approval and
   sales-based milestones of up to $510.0&amp;#160;million for the ACE-011 program and up to an additional
   $437.0&amp;#160;million for each of the three discovery stage programs. The companies will co-promote the
   products in North America. Acceleron will receive tiered royalties on worldwide net sales.

   &lt;div align="justify" style="font-size: 10pt; margin-top: 10pt"&gt;The agreement will continue until the Company has satisfied all royalty payment obligations to
   Acceleron and the Company has either exercised or forfeited all of its options under the agreement.
   Upon the Company&amp;#8217;s full satisfaction of its royalty payment obligations to Acceleron under the
   agreement, all licenses granted to the Company by Acceleron under the agreement will become fully

   Pharmion, the Company will pay $12.5&amp;#160;million for each approval of amrubicin in an initial
   indication by regulatory authorities in the United States and the E.U. to the former shareholders
   of Cabrellis. Upon approval of amrubicin for a second indication in the United States or the E.U.,
   the Company will pay an additional $10.0&amp;#160;million for each market to the former shareholders of
   Cabrellis. Under the terms of the license agreement for amrubicin, the Company is required to make
   milestone payments of $7.0&amp;#160;million and $1.0&amp;#160;million to DSP upon regulatory approval of amrubicin in
   the United States and upon receipt of the first approval in the E.U., respectively, and up to $17.5
   million upon achieving certain annual sales levels in the United
   States. Pursuant to the supply agreement for amrubicin, the Company is to pay DSP a semiannual supply price
   calculated as a percentage of net sales for a period of ten years. In September&amp;#160;2008, amrubicin
   was granted fast-track product designation by the FDA for the treatment of small cell lung cancer

   delivery of certain reports from GlobeImmune on the completed clinical trials with respect to each
   drug candidate program, as set forth in the initial development plan specified in the agreement.
   If the Company does not exercise its options with respect to any drug candidate program or future

   product-by-product, country-by-country basis, GlobeImmune will grant the
   Company an exclusive, fully paid-up, royalty-free, perpetual license to use certain intellectual
   property of GlobeImmune to market and sell the compounds and products developed under the

   &lt;div align="justify" style="font-size: 10pt; margin-top: 10pt"&gt;If the agreement is terminated by the Company at its sole discretion or by GlobeImmune for a
   material breach by the Company, then the Company&amp;#8217;s rights to the compounds and products developed
   under the agreement will revert to GlobeImmune. If the agreement is terminated by the Company for
   a material breach by GlobeImmune, then, among other things, the Company&amp;#8217;s royalty payment
   obligations under the agreement will be reduced by 50%, the Company&amp;#8217;s development milestone payment
   obligations under the agreement will be reduced by 50% or terminated entirely and the Company&amp;#8217;s
   sales milestone payment obligations under the agreement will be terminated entirely.

   &lt;div align="justify" style="font-size: 10pt; margin-top: 10pt"&gt;&lt;b&gt;Agios Pharmaceuticals, Inc.: &lt;/b&gt;On April&amp;#160;14, 2010, the Company entered into a discovery and
   development collaboration and license agreement with Agios Pharmaceuticals, Inc., or Agios, which
   focuses on cancer metabolism targets and the discovery, development and commercialization of
   associated therapeutics. As part of the agreement, the Company paid Agios a $121.2&amp;#160;million
   non-refundable, upfront payment, which was expensed by the Company as research and development in
   the second quarter of 2010. The Company also made an $8.8&amp;#160;million equity investment in Agios Series
   B Convertible Preferred Stock, representing approximately a 10.94% ownership interest in Agios and
   is included in other non-current assets in the Company&amp;#8217;s Consolidated Balance Sheet. The Company
   receives an initial period of exclusivity during which it has the option to develop any drugs
   resulting from the Agios cancer metabolism research platform and may extend this exclusivity period
   by providing Agios additional funding. The Company has an exclusive option to license any resulting
   clinical candidates developed during this period and will lead and fund global development and
   commercialization of certain licensed programs. With respect to each product in a program that the
   Company chooses to license, Agios could receive up to $120.0&amp;#160;million upon achievement of certain
   milestones plus royalties on sales, and Agios may also participate in the development and
   commercialization of certain products in the United States. Agios may also receive a one-time
   milestone payment of $25.0&amp;#160;million upon dosing of the final human subject in a Phase II study, such
   payment to be made only once with respect to only one program.
   &lt;/div&gt;
   &lt;div align="justify" style="font-size: 10pt; margin-top: 10pt"&gt;Unless the agreement is earlier terminated or the option term is extended, the Company&amp;#8217;s
   option will terminate on April&amp;#160;14, 2013. However, if certain development targets are not met, the
   Company may unilaterally extend the option term: (a)&amp;#160;for up to an additional one year without
   payment; (b)&amp;#160;subject to certain criteria and upon payment of certain predetermined amounts to
   Agios, for up to two additional years thereafter.
   &lt;/div&gt;
   &lt;div align="justify" style="font-size: 10pt; margin-top: 10pt"&gt;Following expiration of the option, the agreement will continue in place with respect to programs
   to which the Company has exercised its option or otherwise is granted rights to develop. The
   agreement may expire on a product-by-product and country-by-country basis as the Company satisfies
   its payment obligation with respect to each product in each country. Upon the expiration of the
   agreement with respect to a product in a country, all licenses granted by one party to the other
   party for such product in such country shall become fully paid-up, perpetual, sub licensable,
   irrevocable and royalty-free.

   &lt;/div&gt;
   &lt;div align="justify" style="font-size: 10pt; margin-top: 10pt"&gt;The party terminating under (i)&amp;#160;or (ii)(a) above has the right to terminate on a program-by-program
   basis leaving the agreement in effect with respect to remaining programs. If the agreement or any
   program is terminated by the Company for convenience or by Agios for a material breach or
   bankruptcy by the Company, then, among other things, depending on the type of program and
   territorial rights: (a)&amp;#160;certain licenses granted by the Company to Agios shall stay in place,
   subject to Agios&amp;#8217; payment of certain royalties to the Company: and (b)&amp;#160;Celgene will grant Agios a
   non-exclusive, perpetual, royalty-free license to certain technology developed in the conduct of
   the collaboration and used in the program (which license is exclusive with respect to certain
   limited collaboration technology). If the agreement or any program is terminated by the Company
   for a material breach or bankruptcy by Agios, then, among other things, all licenses granted by
   Celgene to Agios will terminate and: (i)&amp;#160;Celgene&amp;#8217;s license from Agios will continue in perpetuity
   and all payment obligations will be reduced or will terminate; (ii)&amp;#160;Celgene&amp;#8217;s license for certain
   programs will become exclusive worldwide: and (iii)&amp;#160;with regard to any program where the Company
   has exercised buy-in rights, Agios shall continue to pay certain royalties to Celgene.
   &lt;/div&gt;
   &lt;div align="justify" style="font-size: 10pt; margin-top: 10pt"&gt;The Company has determined that Agios is a variable interest entity; however, the Company is not
   the primary beneficiary of Agios. Although the Company would have the right to receive the benefits
   from the collaboration and license agreement and it is probable that this agreement incorporates
   the activities that most significantly impact the economic performance of Agios for up to six
   years, the Company does not have the power to direct the activities under the collaboration and
   license agreement as Agios has the decision-making authority for the Joint Steering Committee and
   Joint Research Committee until the Company exercises its option to license a product. The Company&amp;#8217;s
   interest in Agios is limited to its 10.94% equity ownership and it does not have any obligations or
   rights to the future losses or returns of Agios beyond this ownership. The collaboration agreement,
   including the upfront payment and series B convertible preferred stock investment, does not entitle
   the Company to participate in future returns beyond the 10.94% ownership and it does not obligate
   the Company to absorb future losses beyond the $8.8&amp;#160;million investment in Agios Series&amp;#160;B
   Convertible Preferred Stock. In addition, there are no other agreements other than the
   collaboration agreement that entitle the Company to receive returns beyond the 10.94% ownership or
   obligate the Company to absorb additional losses.
