 <P STYLE="margin-top:0pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman"><B>Item&nbsp;1.01 Entry into a Material Definitive Agreement. </B></P>
<P STYLE="margin-top:6pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">On August&nbsp;18, 2014, Ligand Pharmaceuticals Incorporated (the &#147;Company&#148;) issued $245.0 million in aggregate principal amount of
its 0.75% Convertible Senior Notes due 2019 (the &#147;Notes&#148;) in a private offering to qualified institutional buyers pursuant to Rule 144A under the Securities Act of 1933, as amended (the &#147;Securities Act&#148;). The aggregate principal
amount of the Notes sold reflects the exercise in full by the initial purchasers of the Notes (the &#147;Initial Purchasers&#148;) of their option to purchase up to an additional $20.0 million in aggregate principal amount of the Notes. The Notes
were issued pursuant to an Indenture, dated as of August&nbsp;18, 2014 (the &#147;Indenture&#148;) between the Company and Wilmington Trust, National Association, as trustee. The Indenture includes customary terms and covenants, including certain
events of default after which the Notes may be due and payable immediately. </P> <P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">The Notes are the Company&#146;s unsecured senior
obligations. The Notes bear interest semi-annually at a rate of 0.75%&nbsp;per year, payable on February&nbsp;15 and August&nbsp;15 of each year. The Notes will mature on August&nbsp;15, 2019, unless earlier repurchased or converted in accordance
with their terms prior to such date. Prior to May&nbsp;15, 2019, the Notes will be convertible at the option of the holders only upon satisfaction of certain conditions and during certain periods. From and after May&nbsp;15, 2019, the notes will be
convertible without regard to those conditions at any time until the close of business on the second scheduled trading day immediately preceding the maturity date. Upon conversion, an amount up to the principal amount of the notes will be paid in
cash and, if applicable, any amount above the principal amount will be paid in common stock or cash at the Company&#146;s option. Holders of the Notes will have the right to require the Company to repurchase all or some of their Notes at 100% of
their principal amount, plus any accrued and unpaid interest, upon the occurrence of certain events. The conversion rate for the Notes will initially be 13.3251 shares per $1,000 principal amount, which is equivalent to an initial conversion price
of approximately $75.05 per share of common stock, and is subject to adjustment under the terms of the Notes. The initial conversion price of the Notes represents a premium of approximately 35.0% to the $55.59 per share closing price of the
Company&#146;s common stock on August&nbsp;12, 2014. </P> <P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">In connection with the pricing of the Notes on August&nbsp;12, 2014, the Company
entered into privately negotiated convertible note hedge transactions (together, the &#147;Base Convertible Note Hedge Transactions&#148;) with each of Bank of America, N.A. and Deutsche Bank AG, London Branch (together, the &#147;Option
Counterparties&#148;). In addition, on August&nbsp;14, 2014, the Company entered into additional convertible note hedge transactions (the &#147;Additional Convertible Note Hedge Transactions,&#148; and, together with the Base Convertible Note Hedge
Transactions, the &#147;Convertible Note Hedge Transactions&#148;) with each of the Option Counterparties. The Convertible Note Hedge Transactions cover, subject to customary anti-dilution adjustments substantially similar to those applicable to the
Notes, the number of shares of the Company&#146;s common stock underlying the Notes, as described below. On August&nbsp;12, 2014 and August&nbsp;14, 2014, the Company also entered into separate, privately negotiated warrant transactions (the
&#147;Base Warrant Transactions&#148; and the &#147;Additional Warrant Transactions,&#148; respectively, and together, the &#147;Warrant Transactions&#148;) with each of the Option Counterparties initially relating to the number of shares of the
Company&#146;s common stock underlying the Convertible Note Hedge Transactions, subject to customary anti-dilution adjustments. </P> <P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">The
Convertible Note Hedge Transactions are expected generally to reduce the potential dilution and/or offset the cash payments the Company is required to make in excess of the principal amount upon conversion of the Notes in the event that the market
price of the Company&#146;s common stock is greater than the strike price of the Convertible Note Hedge Transactions, which initially corresponds to the initial conversion price of the Notes. The Warrant Transactions could separately have a dilutive
effect if the market price of the Company&#146;s common stock exceeds the strike price of the Warrant Transactions. The strike price of the Warrant Transactions will initially be approximately $125.08 per share of the Company&#146;s common stock and
is subject to certain adjustments under the terms of the Warrant Transactions. The Convertible Note Hedge Transactions and the Warrant Transactions are separate transactions, in each case, entered into by the Company with the Option Counterparties,
and are not part of the terms of the Notes and will not affect any holder&#146;s rights under the Notes. Holders of the Notes will not have any rights with respect to the Convertible Note Hedge Transactions or the Warrant Transactions. </P>
<P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">The net proceeds from the sale of the Notes, including net proceeds from the exercise in full by the Initial Purchasers of their option to
purchase up to an additional $20.0 million in aggregate principal amount of the Notes, were approximately $239.1 million, after deducting the Initial Purchasers&#146; discounts and commissions and the

 <P STYLE="margin-top:0pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman">
estimated offering and expenses payable by the Company. The Company used approximately $36.5 million of the net proceeds to pay the cost of the Convertible Note Hedge Transactions, after taking
into account the proceeds to the Company of the Warrant Transactions, and approximately $37.8 million of the net proceeds to repurchase shares of the Company&#146;s common stock from purchasers of the Notes in privately negotiated transactions
concurrently with the offering. The Company expects to use the remainder of the net proceeds from the offering of the notes for additional share repurchases up to a total of $200.0 million inclusive of the repurchases concurrent with the convertible
transaction, which repurchases may be effected from time to time in open-market transactions, in negotiated transactions or pursuant to an accelerated share repurchase transaction or similar transaction, and for other general corporate purposes. The
Company may also use a portion of the net proceeds to acquire new businesses through one or more strategic transactions; however, the Company has no current commitments or obligations with respect to any acquisitions or strategic transactions. </P>

claim or any action, suit or proceeding arising therefrom, whether or not such Indemnified Party is a party thereto and whether or not such claim, action, suit or proceeding is initiated or brought by or on behalf of Counterparty. This indemnity

such assignment, to pay the assignee on any payment date, an amount greater than Dealer would have been required to pay in the absence of such assignment, (vi)&nbsp;no Event of Default, Potential Event of Default or Termination Event existing or
occurring as a result of such assignment and (vii)&nbsp;Counterparty causing the transferee to make such Payee Tax Representations and to provide such tax documentation as may be reasonably requested by Dealer to permit Dealer to determine that the

Expiration Date shall be the prevailing market value per Share determined by the Calculation Agent in a commercially reasonable manner. &#147;<B>Final Disruption Date</B>&#148; has the meaning provided in <U>Annex A</U> to this Confirmation.
Notwithstanding the foregoing and anything to the contrary in the Equity Definitions, if a Market Disruption Event occurs on any Expiration Date, the Calculation Agent, acting commercially reasonably, may determine that such Expiration Date is a

on transactions in the Shares on such Disrupted Day taking into account the nature and duration of such Market Disruption Event on such day. Any Scheduled Trading Day on which, as of the date hereof, the Exchange is scheduled to close prior to its
normal close of trading shall be deemed not to be a Scheduled Trading Day; if a closure of the Exchange prior to its normal close of trading on any Scheduled Trading Day is scheduled following the date hereof, but prior to the open of the regular
trading session of the Exchange on such day, then such Scheduled Trading Day shall be deemed to be a Disrupted Day in full. Section 6.6 of the Equity Definitions shall not apply to any Valuation Date occurring in respect of an Expiration

Trading Day determined in the manner described in the second preceding sentence as the Expiration Date for the remaining Warrants for such Component, and (ii) the VWAP Price for such Disrupted Day shall be determined by the Calculation Agent based
on transactions in the Shares on such Disrupted Day taking into account the nature and duration of such Market Disruption Event on such day. Any Scheduled Trading Day on which, as of the date hereof, the Exchange is scheduled to close prior to its
normal close of trading shall be deemed not to be a Scheduled Trading Day; if a closure of the Exchange prior to its normal close of trading on any Scheduled Trading Day is scheduled following the date hereof, but prior to the open of the regular
trading session of the Exchange on such day, then such Scheduled Trading Day shall be deemed to be a Disrupted Day in full. Section 6.6 of the Equity Definitions shall not apply to any Valuation Date occurring in respect of an Expiration
