INTRODUCTION

                This Rule 13e-3 Transaction Statement (the "Statement") relates
        to the exercise by Ligand Pharmaceuticals Incorporated, a Delaware
        corporation ("Ligand"), of the option (the "Stock Purchase Option")
        granted to it under the Amended and Restated Certificate of
        Incorporation (the "ALRT Certificate") of Allergan Ligand Retinoid
        Therapeutics, Inc., a Delaware corporation ("ALRT" or the "Issuer"), to
        purchase all of the issued and outstanding shares of Callable Common
        Stock, par value $0.001 per share, of ALRT (the "Transaction").
        Notwithstanding the filing of this Statement, Ligand does not admit that
        the Transaction is subject to Rule 13e-3 of the Securities Exchange Act
        of 1934, as amended.

ITEM 1. ISSUER AND CLASS OF SECURITY SUBJECT TO THE TRANSACTION.

        (a)     ALRT is the issuer of the equity security which is the subject
                of the Transaction. The address of ALRT's principal executive
                offices is 2525 Dupont Drive, Irvine, California 92612.

        (b)     The exact title of the equity security which is the subject of
                this filing is the Callable Common Stock, par value $0.001 per
                share, of ALRT (the "Callable Common Stock"). The number of
                shares of Callable Common Stock outstanding as of November 10,
                1997, the most recent practicable date, was 3,250,000 shares.
                The approximate number of holders of record of the Callable
                Common Stock was approximately 1056 as of that date.

        (c)     The principal market on which the Callable Common Stock is being
                traded is the Nasdaq National Market. From its issuance on June
                3, 1995 until June 3, 1997, the Callable Common Stock was not
                traded separately, but was traded as part of units (the
                "Units"), each Unit consisting of one share of Callable Common
                Stock and two Warrants, each Warrant to purchase one share of
                Ligand Common Stock. The Units traded under the symbol "ALRIZ."
                The following chart sets forth the range of high and low sale
                prices for the Units on the Nasdaq National Market for each
                quarterly period from September 30, 1995 until November 14,
                1997:

</TABLE>

        (d)     To the best of Ligand's knowledge after making a reasonable
                inquiry, ALRT has not paid any dividends on the Callable Common
                Stock during the past two years. Section 4.4(c) of the ALRT
                Certificate provides that ALRT cannot declare or pay dividends
                to the holders of Callable Common Stock without the affirmative
                vote of the holders of a majority of the issued and outstanding
                shares of the Special Common Stock of ALRT.

        (e)     All outstanding shares of the Callable Common Stock were
                initially issued on June 3 ,1995 in connection with a registered
                offering under the Securities Act of 1933 (the "Offering"). Upon
                completion of the Offering on June 3, 1995, 3,250,000 Units were
                issued at an offering price of $10.00 per Unit. The Offering
                raised net proceeds of $26.8 million for ALRT. Since the
                Offering, there has been no underwritten public offerings of the
                Callable Common Stock for cash registered under the Securities
                Act of 1933 or exempt from registration thereunder pursuant to
                Regulation A.

        (f)     None.

                        Purchase Agreement") whereby, if Ligand exercises the
                        Stock Purchase Option, Allergan has the right to acquire
                        certain assets from ALRT (the "Asset Purchase Option").
                        On September 24, 1997, Ligand and Allergan announced
                        that they had exercised their respective option to
                        purchase the Callable Common Stock and certain assets of
                        ALRT. Ligand's notice of exercise of the Stock Purchase
                        Option included stock purchase option exercise price of
                        $21.97 per share of outstanding Callable Common Stock,
                        the original exercise price designated for the exercise
                        of the Stock Purchase Option at any time prior to June
                        3, 1998. Allergan's notice of exercise of its Asset
                        Purchase Option included an aggregate asset purchase
                        price of $8.9 million (the "Asset Purchase Option
                        Exercise Price"), the original exercise price designated
                        for the exercise of the Asset Purchase Option at any
                        time prior to June 3, 1998 under the governing Asset
                        Purchase Agreement. The Asset Purchase Option Exercise
                        Price will be paid in cash to ALRT concurrently with the
                        payment to holders of ALRT Callable Common Stock of the
                        Stock Purchase Option Exercise Price and may be used to
                        pay a portion of such Stock Purchase Option Exercise
                        Price.

                             Ligand and Allergan also agreed to restructure the
                        terms and conditions relating to research, development,
                        commercialization and sublicense rights for the ALRT
                        compounds in the period following the closing of the
                        exercise of Ligand's Stock Purchase Option and
                        Allergan's Asset Purchase Option. Prior to the
                        restructuring and following the exercise of the Stock
                        Purchase Option and Asset Purchase Option, Ligand and
                        Allergan would have had equal, co-exclusive development,
                        commercialization and sublicense rights in the compounds
                        and assets developed by ALRT and a 50% interest in
                        ALRT's liabilities. Under the restructured arrangement,
                        however, Ligand will receive exclusive, worldwide
                        development, commercialization and sublicense rights to
                        Oral and Topical Panretin (ALRT1057) (currently in
                        pivotal Phase III clinical trials), ALRT1550 (currently
                        in Phase I/IIa clinical trials for oncology
                        applications) and ALRT268 and ALRT324 (two advanced
                        preclinical Retinoid X Receptor ("RXR") selective
                        compounds); Allergan will receive exclusive, worldwide
                        development, commercialization and sublicense rights to
                        ALRT4310, a Retinoic Acid Receptor ("RAR") antagonist
                        being developed for topical application against
                        mucocutaneous toxicity associated with currently
                        marketed retinoids as well as for psoriasis. Allergan
                        will also receive ALRT326 and ALRT4204 (two advanced
                        preclinical RXR selective compounds). In addition,
                        Ligand and Allergan have participated in a lottery for
                        each of the approximately 2,000 retinoid compounds
                        existing in the ALRT compound library as of the closing
                        date (the "Lottery"), with each party to acquire
                        exclusive, worldwide development, commercialization and
                        sublicense rights to the compounds which they select.
                        Ligand and Allergan will each pay the other a royalty
                        based on net sales of products developed from (i) the
                        compounds selected by each in the Lottery and (ii) the
                        other ALRT compounds to which each acquires exclusive
                        rights. Ligand will also pay to Allergan a royalty based
                        on Ligand's net sales of Targretin for uses other than
                        oncology and dermatology indications; in the event that
                        Ligand licenses commercialization rights to Targretin to
                        a third party, Ligand will pay to Allergan a percentage
                        of royalties payable to Ligand with respect to sales of
                        Targretin other than in oncology and dermatology
                        indications. Under the restructured arrangement, on the
                        closing of the exercise of the Stock Purchase Option 
                        and the Asset Purchase Option, Ligand will pay to 
                        Allergan a non-refundable cash payment in the amount of
                        $4.5 million.

ITEM 4. TERMS OF THE TRANSACTION.

        (a)     The material terms of the Transaction are as follows:

                        This Statement relates to Ligand's exercise of the Stock
                Purchase Option granted to it under the ALRT Certificate to
                purchase all of the outstanding shares of Callable Common Stock.
                ALRT is an off balance sheet entity formed by Ligand and
                Allergan to discover, develop and commercialize pharmaceutical
                products based on retinoids.

                        In May 1995, ALRT and Ligand commenced a registered
                offering under the Securities Act of 1933 (the "Offering"),
                which was completed on June 3, 1995, of 3,250,000 units (the
                "Units"). Each Unit consisted of one share of Callable Common
                Stock and two Warrants (the "Warrants"), each such Warrant
                exercisable for one share of Ligand Common Stock. The Units that
                were issued in connection with the Offering traded on the Nasdaq
                National Market until June 3, 1997, at which time the Callable
                Common Stock and the Warrants were separately listed on the
                Nasdaq National Market.

                        The Offering raised net proceeds for ALRT of $26.8
                million. At the completion of the Offering, Ligand contributed
                $17.5 million in cash and the Warrants in exchange for (i) the
                Stock Purchase Option and (ii) a right to acquire all rights to
                the Panretin(TM)(ALRT1057) product currently under development
                by ALRT. At the same time, Allergan contributed $50.0 million in
                cash to ALRT in exchange for (i) the right to acquire one-half
                of all of ALRT's technologies and other assets in the event
                Ligand exercises the Stock Purchase Option, (ii) an option,
                similar to the Stock Purchase Option to acquire all of the
                Callable Common Stock if Ligand decides not to exercise the
                Stock Purchase Option and (iii) a right similar to Ligand's to
                acquire all rights to the Panretin(TM)(ALRT1057) product under
                development by ALRT.

                        Ligand exercised the Stock Purchase Option granted to it
                under the ALRT Certificate on September 24, 1997 by providing
                written notice of its exercise (the "Stock Purchase Option
                Exercise Notice") to ALRT, the holders of the outstanding shares
                of Special Common Stock of ALRT and the holders of outstanding
                shares of Callable Common Stock. The exercise price of the Stock
                Purchase Option is


<PAGE>   11
                $21.97 per share of outstanding Callable Common Stock, for an
                aggregate exercise price of $71,402,500.00 (the "Stock Purchase
                Option Exercise Price"). The Stock Purchase Option Exercise
                Price was based on Section 5.2 of the ALRT Certificate which
                provides that if the Stock Purchase Option is exercised on or
                before June 3, 1998, the exercise price is $21.97 per share of
                Callable Common Stock, and if it is exercised thereafter, the
                exercise price increases over time in accordance with a schedule
                set forth in such Section. The Stock Purchase Option Exercise
                Notice specifies that 35 percent of the Stock Purchase Option
                Exercise Price shall be paid in cash and the remaining 65
                percent of the Stock Purchase Option Exercise Price shall be
                paid in shares of Ligand Common Stock. The Stock Purchase Option
                Exercise Notice also specifies that notwithstanding the
                foregoing and in accordance with the terms of Article V of the
                ALRT Certificate, Ligand reserves a right at any time prior to
                the closing of the Stock Purchase Option, to make payment of a
                greater amount of the Stock Purchase Option Exercise Price in
                cash than set forth in the Stock Purchase Option Exercise
                Notice. Should Ligand exercise the latter right, it would notify
                stockholders by issuing a press release. The shares of Ligand
                Common Stock will be valued based on the average of the closing
                prices for such stock for the 20 trading days immediately
                preceding the day prior to the Stock Purchase Option Closing
                Date. The date on which all of the issued and outstanding shares
                of Callable Common Stock will be purchased (the "Stock Purchase
                Option Closing Date") is set for November 3, 1997, or such later
                date as the registration statement filed by Ligand conveying the
                issuance of the shares of Ligand Common Stock to be issued in
                partial consideration of the Stock Purchase Option is declared
                effective. 

                        In accordance with the terms of the ALRT Certificate,
                the holders of the Callable Common Stock are obligated to sell
                such shares to Ligand. These stockholders have absolutely no
                investment discretion in connection with Ligand's purchase of
                such outstanding shares of Callable Common Stock. Title to the
                Callable Common Stock will automatically vest in Ligand on the
                Stock Purchase Option Closing Date. The holders of the Callable
                Common Stock may obtain payment of their pro rata portion of the
                Stock Purchase Option Exercise Price from ChaseMellon
                Shareholder Services, L.L.C. (the "Payment Agent") on or within
                5 days after the Stock Purchase Option Closing Date upon
                surrender of their certificates representing their shares of the
                Callable Common Stock. Upon receipt of certificates from the
                holders of the Callable Common Stock, the Payment Agent shall
                pay such holders by mail to their respective addresses set forth
                in ALRT's records or at the addresses otherwise provided by such
                record holders or, if no such addresses are set forth in ALRT's
                records or not otherwise provided, to such record holders at the
                address of ALRT.

        (b)     Not applicable.

ITEM 5. PLANS OR PROPOSALS OF THE ISSUER OR AFFILIATE.

                Following Ligand's purchase of all of the outstanding Callable
        Common Stock, ALRT will be a wholly-owned subsidiary of Ligand. Ligand
        anticipates de-listing ALRT from the Nasdaq National Market and
        suspending its reporting requirements with the Securities and Exchange
        Commission by filing a Form 15. Ligand also intends to replace ALRT's
        officers and Board of Directors with Ligand employees.


                Ligand and Allergan also agreed to restructure the terms and
        conditions relating to research, development, commercialization and
        sublicense rights for the ALRT compounds in the period following the
        closing of the exercise of Ligand's Stock Purchase Option and
        Allergen's Asset Purchase Option. Prior to the restructuring and
        following the exercise of the Stock Purchase Option and Asset Purchase
        Option, Ligand and Allergan would have had equal, co-exclusive
        development, commercialization and sublicense rights in the compounds
        and assets developed by ALRT and a 50% interest in ALRT's liabilities.
        Under the restructured arrangement, however, Ligand will receive
        exclusive, worldwide development, commercialization and sublicense
        rights to Oral and Topical Panretin (ALRT1057) (currently in pivotal
        Phase III clinical trials), ALRT1550 (currently in Phase I/IIa clinical
        trials for oncology applications) and ALRT268 and ALRT324 (two advanced
        preclinical RXR selective compounds); Allergan will receive exclusive,
        worldwide development, commercialization and sublicense rights to
        ALRT4310, an RAR antagonist being developed for topical application
        against mucocutaneous toxicity associated with currently marketed
        retinoids as well as for psoriasis. Allergan will also receive ALRT326
        and ALRT4204 (two advanced preclinical RXR selective compounds). In
        addition, Ligand and Allergan have participated in the Lottery for each
        of the approximately 2,000 retinoid compounds existing in the ALRT
        compound library as of the closing date, with each party to acquire
        exclusive, worldwide development, commercialization and sublicense
        rights to the compounds which they select. Ligand and Allergan will
        each pay the other a royalty based on net sales of products developed
        from (i) the compounds selected by each in the Lottery and (ii) the
        other ALRT compounds to which each acquires exclusive rights. Following
        commercialization of Targretin, Ligand will also pay to Allergan a
        royalty based on Ligand's net sales of Targretin for uses other than
        oncology and dermatology indications; in the event that Ligand licenses
        commercialization rights to Targretin to a third party, Ligand will pay
        to Allergan a percentage of royalties payable to Ligand with respect to
        sales of Targretin other than in oncology and dermatology indications.
        Under the restructured arrangement, on the closing of the exercise of 
        the Stock Purchase Option and the Asset Purchase Option, Ligand will 
        pay to Allergan a non-refundable cash payment in the amount of $4.5 
        million.


ITEM 6. SOURCE AND AMOUNT OF FUNDS OR OTHER CONSIDERATION.

        (a)     The total consideration for the purchase by Ligand of all of the
                issued and outstanding Callable Common Stock is $71,402,500.00.
                The source of this consideration will be shares of Ligand Common
                Stock (65%) and cash payments (35%) from Ligand. The Company
                may use the Asset Purchase Option Exercise Price to pay a 
                portion of the cash payments. The outstanding portions of such 
                cash payment shall be made with the Company's existing cash and
                cash equivalents.

        (b)     The following is an itemized statement of the expenses which are
                expected to be incurred by Ligand in connection with the
                Transaction:

                      Filing Fees:           $30,000.00

                      Legal Fees:           $100,000.00

                      Accounting Fees:       $25,000.00

                      Printing Costs:        $30,000.00

                      Miscellaneous:         $35,000.00

                             Total:         $220,000.00

                ALRT will not be responsible for paying any of such expenses
        associated with the Transaction.

        (c)     Not applicable.

        (d)     Not applicable.


ITEM 7. PURPOSE(S), ALTERNATIVES, REASONS AND EFFECTS.

        (a)     The purpose of the Transaction is to acquire the rights to all
                products and product candidates developed or under development
                by ALRT pursuant to the Development Agreement dated June 3, 1995
                between Ligand, ALRT and Allergan. Concurrently with the closing
                of the Transaction, Allergan will acquire rights to certain
                assets of ALRT. Ligand believes that it is in the best interests
                of Ligand and Ligand's stockholders to exercise the Stock
                Purchase Option at this time. Ligand believed that based upon
                ALRT's accelerated product development and spending rate and
                pursuant to the terms of the ALRT Certificate, the Stock
                Purchase Option would have been triggered by late 1997 to early
                1998. Thus, rather than having the option triggered
                automatically, Ligand believed that it was in the best interest
                of its stockholders to exercise the Stock Purchase Option and
                restructure the utilization of the ALRT assets so that Ligand
                could focus upon and accelerate its research, development and
                commercialization efforts on specific ALRT asset and compounds.

        (b)     As Ligand is exercising certain previously granted rights, no
                other options were considered. ALRT's Board of Directors had
                previously approved a research and development plan for the year
                ending December 31, 1997 which represented an acceleration in
                spending on ALRT's retinoid programs. ALRT had previously
                announced that it anticipated the acceleration in spending could
                result in the use of substantially all of the funds available
                for research and development remaining in ALRT in late 1997 or
                early 1998. Such an acceleration in spending would have resulted
                in the triggering of the Stock Purchase Option under the terms
                of the ALRT Certificate in late 1997 or early 1998.

                Ligand and Allergan together were granted an option (the
                "ALRT1057 Option") to acquire all of ALRT's right, title and
                interest in the ALRT assets related to Panretin (ALRT1057) (the
                "ALRT1057 Assets"). The ALRT1057 Option was exercisable from
                June 3, 1997 through the earlier of June 3, 2000 or 90 days
                following receipt of regulatory approval in certain major
                markets. Before June 3, 1998, the exercise price for the
                ALRT1057 Option was $21.4 million (the "ALRT1057 Purchase
                Price"). In order to exercise the ALRT1057 Option, both Allergan
                and Ligand would have had to decide it was in the best interest
                of their respective stockholders to exercise the ALRT1057
                Option. Ligand determined such an exercise would not be in its
                stockholders best interests since the ALRT1057 Purchase Price
                could not have been used by ALRT to further develop any other
                ALRT compounds. The Stock Purchase Option would be triggered in
                late 1997 or early 1998 regardless of the exercise of the
                ALRT1057 Option.

        (c)     The Transaction is structured pursuant to the terms of the
                previously granted Stock Purchase Option as set forth in the
                ALRT Certificate. This Transaction is being undertaken at this
                time because based on the current levels of product development
                expenditures, ALRT has announced that it could use substantially
                all of the funds available for research and development in late
                1997 or early 1998, which would require Ligand to exercise the
                Stock Purchase Option within a certain period of time or provide
                operating funds to ALRT, or Ligand would lose rights to products
                being developed by ALRT. Pursuant to the terms of the ALRT
                Certificate, unless Ligand exercised its rights under the Stock
                Purchase Option, Ligand would lose all rights to all ALRT
                compounds and other assets. Allergan would then have the ability
                to acquire an exclusive interest in such compounds and other
                assets by exercising the Stock Purchase Option. Upon exercise of
                the Stock Purchase Option by Allergan, the Development Agreement
                would terminate, and Ligand would have no further rights to ALRT
                products and product candidates under such agreement.

        (d)     The Transaction will cause ALRT to become a wholly-owned
                subsidiary of Ligand. ALRT will be de-listed from the Nasdaq
                National Market and will have its public reporting obligations
                suspended. The federal tax consequences to ALRT are that
                utilization of ALRT's losses and other tax carryovers may be
                limited under Section 382 of the Internal Revenue Code of 1986,
                as amended (the "Code").

                Following the Transaction, Ligand will own 100% of the Callable
                Common Stock. As a result, Ligand will indirectly own all of the
                assets of ALRT. Accordingly, Ligand will report 100% of the net
                book value and net earnings of ALRT. There will be no
                significant federal tax consequences to Ligand as a result of
                the exercise of the Stock Purchase Option. Concurrently with the
                closing of the Transaction, Allergan will acquire an undivided
                one-half interest in the assets of ALRT.

                Under the Transaction, the holders of Callable Common Stock will
                be required to dispose of all their outstanding shares of
                Callable Common Stock for consideration equal to each holder's
                pro rata share of the Stock Purchase Option Exercise Price
                identified in Item 4(a) above.

                The following is a discussion of the U.S. federal income tax
                consequences to the holders of Callable Common Stock resulting
                from the exercise of the Stock Purchase Option by Ligand and the
                issuance of shares of Ligand Common Stock and cash for the
                shares of Callable Common Stock pursuant to the Stock Purchase
                Option. This discussion does not deal with all aspects of
                federal taxation that may be relevant to a particular holder of
                Callable Common Stock, or to certain types of holders
                (including, for example, insurance companies, tax-exempt
                organizations, financial institutions or broker-dealers, foreign
                corporations and persons who are not citizens or residents of
                the United States) subject to special treatment under the U.S.
                federal income tax laws. This discussion also does not deal with
                the effects of state, local or foreign income taxation. The
                statements in this discussion are based on current provisions of
                the Internal Revenue Code of 1986, as amended (the "Code"),
                existing, temporary, and currently proposed Treasury
                regulations, existing administrative interpretations and
                judicial decisions. Future legislative, judicial, or
                administrative changes could significantly change such
                authorities either prospectively or retroactively. Neither
                Ligand nor ALRT has requested a ruling from the Internal Revenue
                Service (the "Service") in connection with the Transaction.

                IN VIEW OF THE INDIVIDUAL NATURE OF TAX CONSEQUENCES, HOLDERS OF
                CALLABLE COMMON STOCK ARE URGED TO CONSULT WITH THEIR OWN TAX
                ADVISORS REGARDING THE SPECIFIC TAX CONSEQUENCES TO THEM OF THE
                TRANSACTION, INCLUDING THE APPLICABILITY OF UNITED


<PAGE>   13
                STATES FEDERAL, STATE, LOCAL AND FOREIGN TAX LAWS.

                Holders of Callable Common Stock will recognize a capital gain
                or loss due to the Transaction equal to the difference between
                (a) the amount realized on the Transaction, which will generally
                be equal to the value of the Ligand Common Stock plus any cash
                received and (b) their basis in the Callable Common Stock
                surrendered.

                The gain or loss recognized should be mid-term if the Callable
                Common Stock has been held for more than one year at the time of
                the Transaction and long-term if the Callable Common Stock has
                been held for more than 18 months at the time of the
                Transaction. The Internal Revenue Service ("IRS") may assert,
                however, that the holding period of the Callable Common Stock
                does not begin until such date as the Stock Purchase Option is
                exercised and that capital gain or loss upon exercise of the
                Stock Purchase Option is therefore short-term. Limitations may
                apply to deduction of capital loss.

                To the extent that holders of Callable Common Stock have not
                provided appropriate taxpayer identification numbers on IRS Form
                W-9 or a substitute therefore, such stockholders may be subject
                to backup withholding by Ligand.

ITEM 8. FAIRNESS OF THE TRANSACTION.

        (a)     Ligand reasonably believes that the Transaction, including the
                Company's right to allocate payment of the Stock Purchase Option
                Exercise Price between cash and Ligand Common Stock, is fair to
                the holders of the Callable Common Stock. Ligand chose to
                allocate payment of the exercise price between cash and Ligand
                Common Stock so that it could make payment based upon a
                balancing of its capital needs at the time of exercise against
                certain other factors, such as dilution or other impact of any
                shares of Ligand Common Stock to be issued by Ligand as payment
                of the Stock Purchase Option Exercise Price. None of Ligand's
                directors dissented to the Transaction. William C. Shepherd, who
                was at the time a director of Ligand and a director and
                executive officer of Allergan, abstained from voting on the
                Transaction.

        (b)     The material factors upon which Ligand bases its belief stated
                in Item 8(a) are as follows:

                (1)     Ligand's Stock Purchase Option, including the Company's
                        right to allocate payment of the Stock Purchase Option
                        Exercise Price between cash and Ligand Common Stock, was
                        disclosed to the holders of Callable Common Stock at the
                        time the Callable Common Stock was offered to the public
                        pursuant to the registered Offering, and was described
                        in the prospectus distributed in connection with the
                        Offering. Ligand's Stock Purchase Option, including the
                        Company's right to allocate payment of the Stock
                        Purchase Option Exercise Price between cash and Ligand
                        Common Stock, also was set forth in the ALRT Certificate
                        which was publicly filed both with the Delaware
                        Secretary of State and the Commission prior to the
                        distribution of the Callable Common Stock. Further,
                        pursuant to the ALRT Certificate, the stock certificates
                        for the Callable Common Stock were legended to provide
                        notice to the holders thereof of the Stock Purchase
                        Option. Holders of the Callable Common Stock have also
                        been advised of the Stock Purchase Option in each Form
                        10-K and Form 10-Q filed since the Offering. As a
                        result, every holder of Callable Common Stock received
                        substantial notice as to the terms of the Stock Purchase
                        Option, including the Company's right to allocate
                        payment of the Stock Purchase Option Exercise Price
                        between cash and Ligand Common Stock, both prior to
                        making any investment decision with respect to the
                        Callable Common Stock and subsequently.

                (2)     The ALRT Certificate sets forth the terms of the Stock
                        Purchase Option. Ligand's exercise of the Stock Purchase
                        Option is consistent with the terms set forth in the
                        ALRT Certificate.

                (3)     In accordance with the ALRT Certificate, all holders of
                        Callable Common Stock, regardless of whether affiliated
                        or not, will receive the same consideration and method
                        of payment per share of Callable Common Stock from
                        Ligand.

                (4)     Under the terms of the ALRT Certificate, the holders of
                        the outstanding shares of Callable Common Stock are
                        obligated to deliver their shares to Ligand once Ligand
                        notifies such holders of its intention to exercise the
                        Stock Purchase Option and complies with the procedural
                        requirements set forth in the ALRT Certificate.

        (c)     The ALRT Certificate does not require any approval of the
                stockholders of ALRT for the exercise by Ligand of the Stock
                Purchase Option.

        (d)     After making reasonable inquiry, Ligand believes that the
                directors of ALRT have not retained an unaffiliated
                representative to act solely on behalf of any unaffiliated
                holder of Callable Common Stock.

        (e)     Under the ALRT Certificate, no action is required by either
                ALRT's directors or the holders of the Callable Common Stock to
                effect the Stock Purchase Option.

        (f)     Not applicable.

ITEM 9. REPORTS, OPINIONS, APPRAISALS AND CERTAIN NEGOTIATIONS.

        (a)     Neither Ligand nor, to the best of Ligand's knowledge after
                reasonable inquiry of management of ALRT, ALRT, has received any
                report, opinion (other than opinion of counsel) or appraisal
                from an outside party which is materially related to the
                Transaction.

        (b)     Not applicable.

        (c)     Not applicable.

ITEM 10. INTEREST IN SECURITIES OF THE ISSUER.

        (a)     As of September 22, 1997, no shares of Callable Common Stock
                were beneficially owned by Ligand, by any pension, profit
                sharing or similar plan of Ligand, by any executive officer or
                director of Ligand, or by any associate or majority owned
                subsidiary of Ligand or, to Ligand's knowledge after reasonable
                inquiry of management of ALRT, by ALRT, by any pension, profit
                sharing or similar plan of ALRT, by any executive officer or
                director of ALRT or by any associate or majority owned
                subsidiary of ALRT, except as set out in the following table:

ITEM 11. CONTRACTS, ARRANGEMENTS OR UNDERSTANDINGS WITH RESPECT TO THE ISSUER'S
SECURITIES.

                The ALRT Certificate sets forth the terms of the Transaction
        involving Ligand and ALRT. The ALRT Certificate provides Ligand with the
        Stock Purchase Option under which Ligand obtained the right to purchase
        all, but not less than all, of the issued and outstanding shares of
        Callable Common Stock. The basic terms of the Stock Purchase Option, as
        set forth in the ALRT Certificate, have been described in Items 1, 4 and
        6. See Items 1, 4 and 6 above.

                As of the date of this filing, Ligand and Allergan each own 50
        percent of the issued and outstanding shares of Special Common Stock of
        ALRT. Section 4.4 of the ALRT Certificate provides that upon exercise of
        the Stock Purchase Option, the rights of the holders of Special Common
        Stock to, among other things, elect two directors of ALRT, approve
        certain extraordinary corporate transactions involving ALRT, and approve
        the transfer of any shares of Special Common Stock shall


<PAGE>   16
        terminate. As the Stock Purchase Option has now been exercised by
        Ligand, such rights of the holders of Special Common Stock described in
        the foregoing sentence have accordingly terminated.

                Section 4.5 of the ALRT Certificate provides that ALRT may, on
        and after the exercise of the Stock Purchase Option, redeem all of the
        outstanding shares of Special Common Stock by paying in cash $1.00 per
        share for each redeemed share (the "Redemption Price"). At least 15 days
        before the date of redemption, a written redemption notice shall be
        given to each holder of Special Common Stock by first-class mail,
        postage prepaid, at the holder's address as shown on ALRT's records,
        stating: (i) all of the shares of Special Common Stock to be redeemed,
        (ii) the date fixed for the redemption (the "Redemption Date"), (iii)
        the Redemption Price, and (iv) the place of payment of the Redemption
        Price. On or before the date fixed for redemption, each holder of shares
        of Special Common Stock to be redeemed shall surrender the certificates
        representing these shares to ALRT at the place designated for payment in
        the redemption notice and shall then be entitled to receive payment of

                         Report of Independent Auditors


The Board of Directors and Shareholders
Allergan Ligand Retinoid Therapeutics, Inc.

We have audited the accompanying balance sheets of Allergan Ligand Retinoid
Therapeutics, Inc. as of December 31, 1996 and 1995, the related statement of
operations for the period June 3, 1995 (date operations commenced) through
December 31, 1995 and the year ended December 31, 1996, and the statements of
stockholders' equity, and cash flows for the period December 16, 1994 (date of
incorporation) through December 31, 1995 and the year ended December 31, 1996.
These financial statements are the responsibility of the Company's management.
Our responsibility is to express an opinion on these financial statements based
on our audits.

We conducted our audits in accordance with generally accepted auditing
standards.  Those standards require that we plan and perform the audit to
obtain reasonable assurance about whether the financial statements are free of
material misstatement.  An audit includes examining, on a test basis, evidence
supporting the amounts and disclosures in the financial statements.  An audit
also includes assessing the accounting principles used and significant
estimates made by management, as well as evaluating the overall financial
statements presentation.  We believe that our audits provide a reasonable basis
for our opinion.

In our opinion, the financial statements referred to above present fairly, in
all material respects, the financial position of Allergan Ligand Retinoid
Therapeutics, Inc. at December 31, 1996 and 1995, and the results of its
operations for the period June 3, 1995 (date operations commenced) through
December 31, 1995 and the year ended December 31, 1996, and its cash flows for
the period December 16, 1994 (date of incorporation) through December 31, 1995
and the year ended December 31, 1996, in conformity with generally accepted
accounting principles.

                               December 31, 1996

1. ORGANIZATION AND BUSINESS OPERATIONS

BUSINESS

Allergan Ligand Retinoid Therapeutics, Inc. (the Company) was incorporated in
Delaware in 1994 and commenced operations on June 3, 1995 to continue the
efforts of the Allergan Ligand Joint Venture (Joint Venture), established by
Allergan, Inc. (Allergan) and Ligand Pharmaceuticals Incorporated (Ligand) in
June 1992, to discover, develop and commercialize drugs based on retinoids (the
Products).

On June 3, 1995, the Company and Ligand completed a public offering (the
Offering) of 3.25 million units, each unit consisting of one share of the
Company's callable common stock and two warrants, each to purchase one share of
Ligand common stock.  The Offering raised net proceeds for the Company of $26.8
million.  At the completion of the Offering, Ligand contributed $17.5 million
in cash, as well as warrants in exchange for (i) a right to acquire all of the
Callable Common Stock at specified future dates and amounts and (ii) a right to
acquire all rights to the Panretin (ALRT1057) products, jointly with Allergan,
currently under development by the Company.  At the same time, Allergan
contributed $50.0 million in cash to the Company in exchange for (i) the right
to acquire one-half of all technologies and other assets in the event Ligand
exercises its right to acquire all of the Callable Common Stock, (ii) a similar
right to acquire all of the Callable Common Stock if Ligand does not exercise
its right and (iii) a right to acquire all rights to the Panretin (ALRT1057)
products, jointly with Ligand.

         ALRT's Board of Directors recently approved a research and development
plan for the year ending December 31, 1997 which represents an acceleration in
spending on ALRT's retinoid programs.  The accelerated spending is the result
of more rapid discovery and development of a significantly larger library of
viable retinoid compounds than anticipated at the time of formation of ALRT.
ALRT anticipates the acceleration in spending could result in the use of
substantially all of the funds available for research and development remaining
in ALRT in late 1997 or early 1998.  Ligand and Allergan have certain purchase
options over the Callable Common Stock and the assets of ALRT which could be
triggered by the use of substantially all of ALRT's funds.  There can be no
assurance that Ligand or Allergan will exercise these options.

2. SIGNIFICANT ACCOUNTING POLICIES

USE OF ESTIMATES

The preparation of financial statements in conformity with generally accepted
accounting principles requires management to make estimates and assumptions
that affect the amounts reported in the accompanying financial statements.
Actual results could differ from those estimates.

                   Notes to Financial Statements (continued)


2. SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)

CONCENTRATIONS OF BUSINESS RISK

The Company conducts research and development for the purpose of identifying
and developing retinoid drugs for therapeutic uses and is subject to intense
competition and technological changes in the biotechnology industry.  The
Company is also dependent upon Allergan and Ligand who are primarily
responsible for research, development, marketing and manufacturing on behalf of
the Company.

CASH AND CASH EQUIVALENTS

Cash and cash equivalents consists of demand deposits and bank certificates of
deposit carried at cost which approximates fair value.

MARKETABLE SECURITIES

Marketable securities consist of United States Treasury Bills and debt
instruments of financial institutions and corporations with strong credit
ratings.  The Company determines the fair value of marketable securities based
upon quoted market values.  At December 31, 1996, the fair value of marketable
securities was $169,753 less than cost.  Such reduction in value was recorded
as a charge in stockholders' equity as the marketable securities are available
for sale.

CONCENTRATION OF CREDIT RISKS

The Company invests its excess cash in certificates of deposit and marketable
securities.  The Company has established guidelines with respect to
diversification and maturities designed to maintain safety and liquidity.

RESEARCH AND DEVELOPMENT EXPENSES

The Company contracts with Allergan and Ligand to conduct research, development
and initial clinical testing.  The costs of such work are expensed as incurred.

INCOME TAXES

The Company utilizes the liability method of accounting for income taxes.
Under the liability method, deferred taxes are determined based on the
differences between the financial statement and tax bases of assets and
liabilities using enacted tax rates.

2. SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)

NET LOSS PER CALLABLE COMMON SHARE

Net loss per callable common share is calculated by dividing the net loss by
the number of callable common shares outstanding, which was 3,250,000 at all
times during the period from commencement of operations following the closing
of the initial public offering on June 3, 1995 to December 31, 1996.

3. RELATIONSHIP WITH ALLERGAN AND LIGAND

research activities and development and commercialization of certain products.
In consideration for the License, the Company will pay to Allergan and Ligand a
royalty aggregating 3% of net sales of Products under the License during the
life of applicable patents or, in certain circumstances, for 10 years.

RESEARCH AND DEVELOPMENT AGREEMENT

using their own funds.  The Company is entitled to receive a royalty equal to
6% of net sales of any such independently developed products.  The Company also
has the right to reacquire any such product prior to the earlier of the
commencement of Phase III clinical trials for such product or the exercise or
expiration of the Stock Purchase Option, for an amount equal to costs incurred
by Allergan and/or Ligand plus interest at 25% per year.  Additionally, with
respect to any reacquired product, the Company will pay a royalty equal to 4%
of net sales to the developing party.

PANRETIN (ALRT1057) PURCHASE OPTION

The Company has granted Allergan and Ligand an option (the Panretin (ALRT1057)
Purchase Option) to acquire the Company's Panretin (ALRT1057) Products.  Unless
the Panretin (ALRT1057) Purchase Option has been terminated as to either

3. RELATIONSHIP WITH ALLERGAN AND LIGAND (CONTINUED)

The Company may not distribute or otherwise expend any proceeds received upon
the exercise of the Panretin (ALRT1057) Purchase Option until the earlier of
the exercise or expiration of the Stock Purchase Option.

4. STOCKHOLDERS' EQUITY

STOCK PURCHASE OPTION

The Company's Callable Common Stock is subject to a Stock Purchase Option
agreement pursuant to which Ligand and, in the event not exercised by Ligand,
Allergan may purchase all, but not less than all, of the Callable Common Stock
outstanding at specified prices, subject to adjustment.  The option becomes
exercisable on the earlier of (i) June 3, 1997 or (ii) the quarter in which the
Company's available funds, as defined, decline below $10 million and expires on
the earlier of (a) June 3, 2000 or (b) 90 days subsequent to such a decline in
cash.  The option is not exercisable prior to June 3, 1998 unless the available
funds are less than $60 million at the date of exercise.

The Stock Purchase Option exercise price is $21.97 per share prior to June 3,
1998 and increases in equal amounts on a quarterly basis to $28.56 per share on
March 3, 1999 and to $37.13 per share on March 3, 2000.  The exercise price may
be paid in cash, shares of Allergan or Ligand, or any combination thereof.

The Company may not, until the expiration of the Stock Purchase Option, pay any
dividends, issue additional shares of capital stock, borrow money in excess of
$1 million, merge, liquidate or sell all or substantially all of its assets.

WARRANTS

Each unit sold by the Company in its initial public offering includes two
warrants, each warrant giving the holder the right to purchase one share of
Ligand common stock at a price of $7.12 per share.  The warrants are
exercisable at any time from June 3, 1997 through June 2, 2000, subject to
certain acceleration provisions including the exercise or expiration of the
Stock Purchase Option.  The warrants will trade with the Company's Callable
Common Stock as units until they become exerciseable on June 3, 1997.  After
such date, the warrants will separate from the Company's common stock and
become independently tradable.

4. STOCKHOLDERS' EQUITY (CONTINUED)

SPECIAL STOCK

The Company has issued 200 shares of Special Stock to Allergan and Ligand. The
holders of shares of Special Stock are not entitled to vote, except: (i) as
required by law and (ii) to elect two directors of ALRT, voting as a separate
class. ALRT's Board of Directors consists of a total of five directors. When
entitled to vote, each holder of Special Stock has one vote for each share
standing in his or her name.

The holders of shares of Special Stock do not have the right to any profits of
ALRT as a result of the ownership of such shares. In the event of the
liquidation, dissolution or winding up of ALRT, holders of the Callable Common
Stock shall have a priority over the holders of the Special Stock with respect
to return of capital, and the holders of the shares of Special Stock shall not
otherwise be entitled to participate in any way in the profits or assets of 
ALRT.

In addition, until the Stock Purchase Option is exercised or terminates
unexercised, ALRT cannot, without the affirmative vote of the holders of a
majority of the issued and outstanding shares of Special Stock, voting
separately and as a class: (i) issue any additional shares of capital stock
through a stock split, sale, reorganization or otherwise, (ii) alter, change or
amend the rights, powers, preferences and restrictions of the Special Stock,
(iii) alter or change the provisions of ALRT's Certificate of Incorporation
relating to ALRT's capital stock and the Stock Purchase Option, (iv) merge,
consolidate or reorganize ALRT with or into any other corporation, (v) sell,
liquidate or otherwise dispose of all or substantially all of the assets of
ALRT, (vi) borrow an aggregate of in excess of $1 million outstanding at any
one time, (vii) declare or pay dividends or make any other distributions to
stockholders or (viii) adopt, amend or repeal the Bylaws of ALRT.

5. INCOME TAXES

December 31, 1995 have been recognized as offsets to the deferred tax assets as
realization of such assets is uncertain.  Significant components of the
Company's deferred tax assets as of December 31, 1996 and 1995 are (in
thousands):

Allergan Ligand Retinoid Therapeutics, Inc.

Notes to Financial Statements

1.   Allergan Ligand Retinoid Therapeutics, Inc. (the Company) was incorporated
in Delaware in 1994 and commenced operations on June 3, 1995 to continue the
efforts of the Allergan Ligand Joint Venture (Joint Venture), established by
Allergan, Inc. (Allergan) and Ligand Pharmaceuticals Incorporated (Ligand) in
June 1992, to discover, develop and commercialize drugs based on retinoids.

On June 3, 1995, the Company and Ligand completed a public offering (the
Offering) of 3.25 million units (the Units), each Unit consisting of one share
of the Company's callable common stock (Callable Common Stock) and two warrants
(the Warrants), each to purchase one share of Ligand common stock. The Offering
raised net proceeds for the Company of $26.8 million. At the completion of the
Offering, Ligand contributed $17.5 million in cash, as well as warrants in
exchange for (i) a right to acquire all of the Callable Common Stock at
specified future dates and amounts (Stock Purchase Option) and (ii) a right to
acquire all rights to the Panretin (ALRT1057) product, jointly with Allergan,
currently under development by the Company. At the same time, Allergan
contributed $50.0 million in cash to the Company in exchange for (i) the right
to acquire one-half of technologies and other assets in the event Ligand
exercises its right to acquire all of the Callable Common Stock (Asset Purchase
Option), (ii) a similar right to acquire all of the Callable Common Stock if
Ligand does not exercise its right and (iii) a right to acquire all rights to
the Panretin (ALRT1057) product, jointly with Ligand.

On June 3, 1997, the Units separated and the Callable Common Stock and Warrants
currently trade separately.

ALRT's Board of Directors approved a research and development plan for the year
ending December 31, 1997 which represents an acceleration in spending on ALRT's
retinoid programs. The accelerated spending is the result of more rapid
discovery and development of a significantly larger library of viable retinoid
compounds than anticipated at the time of formation of ALRT. ALRT anticipates
the acceleration in spending could result in the use of substantially all of
the funds available for research and development remaining in ALRT in late 1997
or early 1998.

On September 24, 1997, Ligand and Allergan announced that they had exercised
their respective options to purchase the Callable Common Stock and certain
assets of ALRT. Ligand's notice of exercise of the Stock Purchase Option
included a stock purchase option exercise price of $21.97 per share of
outstanding Callable Common Stock (in the aggregate, "Stock Purchase Option
Exercise Price"), the original exercise price designated for the exercise of
the Stock Purchase Option at any time prior to June 3, 1998. Ligand has filed a
registration statement with the Securities and Exchange Commission registering
the issuance of up to $46,410,000 in Ligand Common Stock as partial payment of
the Stock Purchase Option Exercise Price. Ligand has reserved the right, at any
time prior to the closing of the exercise of the Stock Purchase Option, to make
payment of a greater amount of the Stock Purchase Option Exercise Price in cash
than set forth in its notice of exercise.

Allergan's notice of exercise of its Asset Purchase Option included an aggregate
asset purchase price of $8.9 million (Asset Purchase Option Exercise Price), the
original exercise price designated for the exercise of the Asset Purchase Option
at any time prior to June 3, 1998 under the governing asset purchase agreement.
The Asset Purchase Option Exercise Price will be paid in cash to ALRT
concurrently with the payment to holders of Callable Common Stock of the Stock
Purchase Option Exercise Price and may be used to pay a portion of such Stock
Purchase Option Exercise Price.

The record date for the purchase of the Callable Common Stock is October 14,
1997, and the scheduled closing date was November 3, 1997, pending an effective
registration statement.

2.   In the opinion of management, the accompanying unaudited financial
statements contain all adjustments (consisting only of normal recurring
accruals) necessary to present fairly the financial information contained
therein. These statements do not include all disclosures required by generally
accepted accounting principles. The results of operations for the quarter and
nine months ended September 30, 1997 are not necessarily indicative of the
results to be expected for the year ending December 31, 1997. Net loss per
callable common share is computed by dividing the net loss by the number of
callable common shares outstanding, which was 3,250,000 at all times during the
periods reported.

3.   The Company invests its excess cash in money market funds and debt
instruments of financial institutions and corporations with strong credit
ratings. The Company has established guidelines with respect to the
diversification and maturities in order to maintain safety and liquidity. The
Company considers all highly liquid investments with an original maturity of
three months or less to be cash equivalents. The Company's investments are
classified as available-for-sale and are carried at fair value, with unrealized
gains and losses reported as a separate component of stockholders' equity. The
investments are adjusted for amortization of premiums and discounts to maturity
and such amortization is included in interest income.
