style="line-height:120%;text-align:left;text-indent:48px;font-size:11pt;"><font style="font-family:inherit;font-size:11pt;">As previously reported, Ligand Pharmaceuticals Incorporated (&#8220;Ligand&#8221;) entered into a &#8220;General&#8221; Contingent Value Rights Agreement dated January 27, 2010 (as amended on January 26, 2011) and a &#8220;TR Beta&#8221; Contingent Value Rights Agreement dated January 27, 2010, in connection with its acquisition of Metabasis Therapeutics, Inc., a Delaware corporation (&#8220;Metabasis&#8221;).  These two Agreements (the &#8220;Original Agreements&#8221;) entitle the holders of the applicable contingent value rights (&#8220;CVRs&#8221;) to, in general, receive 50% of the cash value of the proceeds from a license or sale of certain Metabasis drug development programs including, for the &#8220;General&#8221; CVRs, the FPBase inhibitor and DGAT-1 programs and others, and, for the &#8220;TR Beta&#8221; CVRs, the TR Beta program.</font></div><div style="line-height:120%;text-align:left;text-indent:48px;font-size:11pt;"><font style="font-family:inherit;font-size:11pt;"><br></font></div><div style="line-height:120%;text-align:left;text-indent:48px;font-size:11pt;"><font style="font-family:inherit;font-size:11pt;">On May 20, 2014, Ligand entered into an Amendment of &#8220;General&#8221; Contingent Value Rights Agreement and an Amendment of &#8220;TR Beta&#8221; Contingent Value Rights Agreement, each with David F. Hale, as Stockholders&#8217; Representative, and Computershare Inc. (as successor to Mellon Investor Services LLC), as Rights Agent.  The purpose of the two Amendments (the &#8220;Amendments&#8221;) was to appropriately define the effect on the CVRs of a particular contemplated transaction (the &#8220;Transaction&#8221;) among Viking Therapeutics, Inc., a Delaware corporation (&#8220;Viking&#8221;) and Ligand/Metabasis, which had not been contemplated at the time of the Original Agreements</font><font style="font-family:inherit;font-size:11pt;color:#000033;">.</font></div><div style="line-height:120%;text-align:left;text-indent:48px;font-size:11pt;"><font style="font-family:inherit;font-size:11pt;"><br></font></div><div style="line-height:120%;text-align:left;text-indent:48px;font-size:11pt;"><font style="font-family:inherit;font-size:11pt;color:#000033;">In the Transaction, Ligand/Metabasis would grant licenses to Viking under the FBPase inhibitor program, the DGAT-1 program and the TR Beta program (the &#8220;Licenses&#8221;).  Under the Licenses, Ligand/Metabasis would have the potential to receive milestone payments and royalties in cash.  In addition, as further consideration for the Licenses, Viking would pay Ligand/Metabasis upfront fees in the form of shares of stock of Viking at the time of the closing of an initial public offering or a significant private financing by Viking.  Because Ligand/Metabasis&#8217; right to receive such shares is conditional upon and calculated at the time of such a closing, these rights to receive Viking equity as partial consideration for the Licenses are referred to as the &#8220;Contingent Stock Rights&#8221; or &#8220;CSRs.&#8221;  As part of the Transaction, Viking would also obtain other assets, including licenses under two Ligand programs which have no connection with the Original Agreements.</font></div><div style="line-height:120%;text-align:left;text-indent:48px;font-size:11pt;"><font style="font-family:inherit;font-size:11pt;"><br></font></div><div style="line-height:120%;text-align:left;text-indent:48px;font-size:11pt;"><font style="font-family:inherit;font-size:11pt;color:#000033;">In the event the Transaction is entered into and Viking thereafter closes an initial public offering or a significant private financing, Ligand would be obligated to pay the holders of the &#8220;General&#8221; CVRs at least $2,250,000 in cash, less any out-of-pocket costs and expenses reasonably incurred by Ligand/Metabasis in connection with the licensing event, and Ligand would be obligated to pay the holders of the &#8220;TR Beta&#8221; CVRs at least $1,250,000 in cash, less any out-of-pocket costs and expenses reasonably incurred by Ligand/Metabasis in connection with the licensing event.&#160;&#160;&#160;&#160;</font></div><div style="line-height:120%;text-align:left;text-indent:48px;font-size:11pt;"><font style="font-family:inherit;font-size:11pt;"><br></font></div><div style="line-height:120%;text-align:left;text-indent:48px;font-size:11pt;"><font style="font-family:inherit;font-size:11pt;color:#000033;">The Amendment of &#8220;General&#8221; Contingent Value Rights Agreement contains a provision amending the &#8220;Proceeds&#8221; participation percentage under the &#8220;General&#8221; CVRs in a limited way, with the effect of increasing by $350,000 the total amount payable to the holders of the &#8220;General&#8221; CVRs in the event of a CSRs payout as compared to the total amount which in the absence of such provision would have been payable to the holders of the &#8220;General&#8221; CVRs in the event of a CSRs payout.  I.e., as a result of the Amendment of &#8220;General&#8221; Contingent Value Rights Agreement provision, in the event the Transaction is entered into and Viking thereafter closes an initial public offering or a significant private financing, Ligand would be obligated to pay the holders of the &#8220;General&#8221; CVRs at least $2,600,000 in cash, less any out-of-pocket costs and expenses reasonably incurred by Ligand/Metabasis in connection with the licensing event.</font><font style="font-family:inherit;font-size:11pt;">&#160;&#160;&#160;&#160;</font></div><div style="line-height:120%;text-align:left;text-indent:48px;font-size:11pt;"><font style="font-family:inherit;font-size:11pt;"><br></font></div><div style="line-height:120%;text-align:left;text-indent:48px;font-size:11pt;"><font style="font-family:inherit;font-size:11pt;">The Amendments further amend the Original Agreements by </font></div><div style="line-height:120%;text-align:left;padding-left:96px;font-size:11pt;"><font style="font-family:inherit;font-size:11pt;"><br></font></div><table cellpadding="0" cellspacing="0" style="font-family:Times New Roman; font-size:10pt;"><tr><td style="width:96px;"></td><td></td></tr><tr><td style="vertical-align:top"><div style="line-height:120%;font-size:11pt;padding-left:72px;"><font style="font-family:inherit;font-size:11pt;">&#8226;</font></div></td><td style="vertical-align:top;padding-left:36px;"><div style="line-height:120%;text-align:left;font-size:11pt;text-indent:-36px;"><font style="font-family:inherit;font-size:11pt;color:#000033;">anticipating that under the Transaction agreement </font><font style="font-family:inherit;font-size:11pt;">Ligand/Metabasis could receive shares of stock of Viking both under the CSRs (in respect of the Licenses) and also under similar </font></div></td></tr></table><br><div><div style="line-height:120%;text-align:left;font-size:8pt;"><font style="font-family:inherit;font-size:8pt;"><br></font></div></div><hr style="page-break-after:always"><a name="s4A23FB9EEA681934E09B211934F46C89"></a><div></div><br><div style="line-height:120%;padding-left:96px;text-align:left;"><font style="font-family:inherit;font-size:11pt;">conditional equity rights in respect of licenses of unrelated assets; establishing that the allocation to the CSRs of portions of such total number of shares will be in accordance with specified ratios;  and providing that the fairness of such proportions, if established in good faith, are conclusive and binding for CVR purposes.

Pursuant to Section 5.2(a) of the Agreement, this Amendment is effective upon the signatures only of Ligand Pharmaceuticals Incorporated, a Delaware corporation (authorized by a Board Resolution) and the Rights Agent, accompanied by the consent of the Stockholders&#8217; Representative.

Hale, as Stockholders&#8217; Representative (the &#8220;Stockholders&#8217; Representative&#8221;), and Computershare Inc., a Delaware corporation (successor to Mellon Investor Services LLC, a New Jersey limited liability company), as Rights Agent (the &#8220;Rights Agent&#8221;) and as initial TR Beta CVR Registrar.  Pursuant to Section 5.2(a) of the Agreement, this Amendment is effective upon the signatures only of Ligand Pharmaceuticals Incorporated, a Delaware corporation (authorized by a Board Resolution) and the Rights Agent, accompanied by the consent of the Stockholders&#8217; Representative.  Pursuant to Section 5.4 of the Agreement, every Holder shall be bound by this Amendment.  </font></div><div style="line-height:120%;padding-bottom:16px;text-align:justify;text-indent:48px;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;">Capitalized terms not otherwise defined in this Amendment shall have the meanings ascribed to them in the Agreement.  References herein to &#8220;Ligand&#8221; shall be understood to mean Ligand Pharmaceuticals Incorporated, a Delaware corporation, and its consolidated group (including without limitation Target), all together; unless the context requires &#8220;Ligand&#8221; to be understood to mean Ligand Pharmaceuticals Incorporated, a Delaware corporation, in which case the term shall be understood to mean Ligand Pharmaceuticals Incorporated, a Delaware corporation.</font></div><div style="line-height:120%;padding-bottom:16px;text-align:justify;text-indent:48px;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;">1. &#160;&#160;&#160;&#160;</font><font style="font-family:inherit;font-size:10pt;text-decoration:underline;">Transaction</font><font style="font-family:inherit;font-size:10pt;">.  Ligand is contemplating a transaction (the &#8220;Transaction&#8221;) in which Ligand would cause Target to grant licenses of one or more drug candidates and/or technology and/or Intellectual Property from the TR Beta Program (the &#8220;Transaction TR Beta Program License&#8221;) to Viking Therapeutics, Inc., a Delaware corporation (&#8220;Viking&#8221;).  As part of the Transaction, Viking would also be capitalized with other assets, including without limitation licenses of one or more drug candidates and/or technology and/or Intellectual Property from Target&#8217;s FBPase Inhibitor Program and one or more drug candidates and/or technology and/or Intellectual Property from Target&#8217;s DGAT-1 Program.   Under the Transaction TR Beta Program License, Ligand and/or Target would have milestone payment and royalty rights.  In addition, as further consideration for the Transaction TR Beta Program License, Viking would give Ligand a contingent right to receive a calculated number and type of shares of stock of Viking (the &#8220;TR Beta Program Contingent Stock Right&#8221;).  In particular, </font></div><div style="line-height:120%;padding-bottom:16px;text-align:justify;text-indent:48px;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;">(a)&#160;&#160;&#160;&#160;Ligand shall have the right to receive such calculated number and type of shares if and when Viking closes the first private offering of Viking shares for which Ligand affirmatively elects to trigger the TR Beta Program Contingent Stock Right (provided that Viking has not previously closed an initial public offering of Viking shares) &#8211; this is referred to as the &#8220;Private Trigger&#8221;; and </font></div><div style="line-height:120%;padding-bottom:16px;text-align:justify;text-indent:48px;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;">(b)&#160;&#160;&#160;&#160;Ligand shall have the right to receive such calculated number and type of shares if and when Viking closes an initial public offering of Viking shares (provided that Ligand has not previously affirmatively elected to trigger the TR Beta Program Contingent Stock Right for a private offering of stock as contemplated in subsection 1(a) above) &#8211; this is referred to as the &#8220;Public Trigger.&#8221; </font></div><div style="line-height:120%;padding-bottom:16px;text-align:justify;text-indent:48px;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;">2.&#160;&#160;&#160;&#160;</font><font style="font-family:inherit;font-size:10pt;text-decoration:underline;">Public or Private Trigger Payout is Proceeds</font><font style="font-family:inherit;font-size:10pt;">.  </font></div><div style="line-height:120%;padding-bottom:16px;text-align:justify;text-indent:96px;font-size:11.5pt;"><font style="font-family:inherit;font-size:11.5pt;">(a)</font><font style="font-family:inherit;font-size:10pt;">&#160;&#160;&#160;&#160;If, as and when Ligand receives from Viking shares of stock of Viking in respect of the TR Beta Program Contingent Stock Right or receives from Viking other consideration in lieu of shares of stock of Viking in respect of the TR Beta Program Contingent Stock Right (e.g., if the Transaction agreement is amended to provide for such other consideration to be received in lieu), the shares so received (and the total fair market value of such other consideration received in lieu) shall be deemed Proceeds received by Ligand in connection with a TR Beta Licensing Event for a TR Beta Program.  </font></div><div style="line-height:120%;padding-bottom:16px;text-align:justify;text-indent:96px;font-size:11.5pt;"><font style="font-family:inherit;font-size:11.5pt;">(b)</font><font style="font-family:inherit;font-size:10pt;">&#160;&#160;&#160;&#160;For the purpose of calculating the TR Beta Licensing Payment Amounts/TR Beta CVR Payment Amounts associated with the Transaction agreement, it is acknowledged that the TR Beta Licensing Event associated with the Transaction agreement would occur before the sixth anniversary of the Effective Time; and that therefore such TR Beta Licensing Payment Amounts/TR Beta CVR Payment Amounts would be 50% of actual Proceeds received by Ligand before the Outside Date, less any out-of-pocket costs and expenses reasonably incurred by Ligand, </font></div><br><div></div><hr style="page-break-after:always"><a name="s9A287D6D2C3302659E331F7D996FEF16"></a><div><div style="line-height:120%;text-align:right;font-size:11.5pt;"><font style="font-family:inherit;font-size:11.5pt;"><br></font></div></div><br><div style="line-height:120%;padding-bottom:16px;text-align:justify;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;">or any of its subsidiaries or Affiliates, in connection with such TR Beta Licensing Event (including reasonable attorneys fees and brokers commissions).
