                                                                       EXHIBIT B

            Void after 5:00 p.m. New York Time, on [________, ______]
         Warrant to Purchase __________ Shares of Common Stock or such
            additional shares as this Warrant may entitle the holder
               to purchase pursuant to provisions of this Warrant.


                        WARRANT TO PURCHASE COMMON STOCK

                                       OF

                       3-DIMENSIONAL PHARMACEUTICALS, INC.



          This is to Certify That, FOR VALUE RECEIVED, __________ or assigns
("Holder"), is entitled to purchase, subject to the provisions of this Warrant,
from 3-Dimensional Pharmaceuticals, Inc., a Delaware corporation (the
"Company"), _______ fully paid, validly issued and nonassessable shares of
Common Stock, par value $.001 per share, of the Company ("Common Stock") at a
price of $____ per share during the Exercise Period (as defined below). The
number of shares of Common Stock to be received upon the exercise of this
Warrant and the price to be paid for each share of Common Stock may be adjusted
from time to time as hereinafter set forth. The shares of Common Stock
deliverable upon such exercise, and as adjusted from time to time, are
hereinafter sometimes referred to as "Warrant Shares" and the exercise price of
a share of Common Stock in effect at any time and as adjusted from time to time
is hereinafter sometimes referred to as the "Exercise Price". This Warrant is
being issued in connection with the issuance by the Company of Warrants to
purchase shares of Common Stock and promissory notes in the aggregate principal
amount of up to $______________ (the "Notes"), pursuant to a Loan Agreement
dated as of _________________ (the "Agreement").


    a.    EXERCISE OF WARRANT.

          i.        This Warrant may be exercised in whole or in part at any
               time or from time to time on or after _____, _____ until 5 p.m.
               New York City Time on _____, _____ (the "Exercise Period");
               provided, however, that if such day is a day on which banking
               institutions in the State of New York are authorized by law to
               close, then on the next succeeding day which shall not be such a
               day. This Warrant may be exercised by presentation and surrender
               hereof to the Company at its principal office, or at the office
               of its stock transfer agent, if any, with the Purchase Form
               annexed hereto duly executed and accompanied by payment of the
               Exercise Price for the number of Warrant Shares specified in such
               form. As soon as practicable after each such exercise of the
               warrants, but not later than seven (7) days from the date of such
               exercise, the Company shall issue and deliver to the Holder a
               certificate or certificate for the Warrant Shares issuable upon
               such exercise, registered in the name of the
<PAGE>

               Holder or its designee. If this Warrant should be exercised in
               part only, the Company shall, upon surrender of this Warrant for
               cancellation, execute and deliver a new Warrant evidencing the
               rights of the Holder thereof to purchase the balance of the
               Warrant Shares purchasable thereunder. Upon receipt by the
               Company of this Warrant at its office, or by the stock transfer
               agent of the Company at its office, in proper form for exercise,
               the Holder shall be deemed to be the holder of record of the
               shares of Common Stock issuable upon such exercise,
               notwithstanding that the stock transfer books of the Company
               shall then be closed or that certificates representing such
               shares of Common Stock shall not then be physically delivered to
               the Holder.

          ii.       At any time during the Exercise Period, the Holder may, at
               its option, exchange this Warrant, in whole or in part (a
               "Warrant Exchange") into the number of Warrant Shares determined
               in accordance with this Section (a)(2), by surrendering this
               Warrant at the principal office of the Company or at the office
               of its stock transfer agent, accompanied by a notice stating such
               Holder's intent to effect such exchange, the number of Warrant
               Shares to be exchanged and the date on which the Holder requests
               that such Warrant Exchange occur (the "Notice of Exchange"). The
               Warrant Exchange shall take place on the date specified in the
               Notice of Exchange or, if later, the date the Notice of Exchange
               is received by the Company (the "Exchange Date"). Certificates
               for the shares issuable upon such Warrant Exchange and, if
               applicable, a new warrant of like tenor evidencing the balance of
               the shares remaining subject to this Warrant, shall be issued as
               of the Exchange Date and delivered to the Holder within seven (7)
               days following the Exchange Date. In connection with any Warrant
               Exchange, this Warrant shall represent the right to subscribe for
               and acquire the number of Warrant Shares (rounded to the next
               highest integer) equal to (i) the number of Warrant Shares
               specified by the Holder in its Notice of Exchange (the "Total
               Number") less (ii) the number of Warrant Shares equal to the
               quotient obtained by dividing (A) the product of the Total Number
               and the existing Exercise Price by (B) the Fair Market Value.
               "Fair Market Value" shall mean: (1) if the Common Stock is listed
               on a National Securities Exchange or admitted to unlisted trading
               privileges on such exchange or listed for trading on the NASDAQ
               system, the average of the last reported sale prices of the
               Common Stock on such exchange or system for the twenty (20)
               business days ending on the last business day prior to the date
               for which the determination is being made; or (2) if the Common
               Stock is not so listed or admitted to unlisted trading
               privileges, the average of the means of the last reported bid and
               asked prices reported by the National Quotation Bureau, Inc. for
               the twenty (20) business days ending on the last business day
               prior to the date for which the determination is being made; or
               (3) if the Common Stock is not so listed or admitted to unlisted
               trading privileges and bid and asked prices are not so reported,
               an amount, not less than book value thereof as at the
<PAGE>

               end of the most recent fiscal year of the Company ending prior to
               the Exchange Date, determined in such reasonable manner as may be
               prescribed by the Board of Directors of the Company.

   b.          RESERVATION OF SHARES. The Company shall at all times reserve for
          issuance and/or delivery upon exercise of this Warrant such number of
          shares of its Common Stock as shall be required for issuance and
          delivery upon exercise of the Warrants.

   c.          FRACTIONAL SHARES. No fractional shares or script representing
          fractional shares shall be issued upon the exercise of this Warrant.
          With respect to any fraction of a share called for upon any exercise
          hereof, the Company shall pay to the Holder an amount in cash equal to
          such fraction multiplied by the Fair Market Value of a share.

   d.          EXCHANGE, TRANSFER, ASSIGNMENT OR LOSS OF WARRANT.

               (1)        This Warrant is exchangeable, without expense, at the
                    option of the Holder, upon presentation and surrender hereof
                    to the Company or at the office of its stock transfer agent,
                    if any, for other warrants of different denominations
                    entitling the holder thereof to purchase in the aggregate
                    the same number of shares of Common Stock purchasable
                    hereunder. Subject to the restrictions set forth in
                    subparagraph (ii) below, upon surrender of this Warrant to
                    the Company at its principal office or at the office of its
                    stock transfer agent, if any, with the Assignment Form
                    annexed hereto duly executed and funds sufficient to pay any
                    transfer tax, the Company shall, without charge, execute and
                    deliver a new Warrant in the name of the assignee named in
                    such instrument of assignment and this Warrant shall
                    promptly be canceled. This Warrant may be divided or
                    combined with other warrants which carry the same rights
                    upon presentation hereof at the principal office of the
                    Company or at the office of its stock transfer agent, if
                    any, together with a written notice specifying the names and
                    denominations in which new Warrants are to be issued and
                    signed by the Holder hereof. The term "Warrant" as used
                    herein includes any Warrants into which this Warrant may be
                    divided or exchanged. Upon receipt by the Company of
                    evidence satisfactory to it of the loss, theft, destruction
                    or mutilation of this Warrant, and (in the case of loss,
                    theft or destruction) of reasonably satisfactory
                    indemnification, and upon surrender and cancellation of this
                    Warrant, if mutilated, the Company will execute and deliver
                    a new Warrant of like tenor and date. Any such new Warrant
                    executed and delivered shall constitute an additional
                    contractual obligation on the part of the Company, whether
                    or not this Warrant so lost, stolen, destroyed, or mutilated
                    shall be at any time enforceable by
<PAGE>

                    anyone.

               (2)        This Warrant and the shares of Common Stock issuable
                    upon exercise hereof have not been registered under the
                    Securities Act of 1933, as amended, or state securities laws
                    by reason of an exemption therefrom. The shares of Common
                    Stock issuable upon exercise of this Warrant are not
                    transferable except as provided in the Agreement and the
                    Stockholders' Agreement dated as of ____________, as amended
                    from time to time ("Stockholders' Agreement"). Shares of
                    Common Stock issuable upon exercise of this Warrant will
                    bear an appropriate legend to this effect. The restrictions
                    contained herein shall be binding on any transferee of the
                    Common Stock issuable upon exercise of this Warrant and the
                    Company may require any such transferee to execute an
                    instrument agreeing in writing to be bound by these
                    restrictions as a condition to transfer.

   e.          RIGHTS OF THE HOLDER. The Holder shall not, by virtue hereof, be
          entitled to any rights of a shareholder in the Company, either at law
          or equity, and the rights of the Holder are limited to those expressed
          in the Warrant and are not enforceable against the Company except to
          the extent set forth herein.

   f.          ANTI-DILUTION PROVISIONS. The Exercise Price in effect at any
          time and the number and kind of securities purchasable upon the
          exercise of the Warrants shall be subject to adjustment from time to
          time upon the happening of certain events as follows:

          i.   In case the Company shall (i) declare a dividend or make a
          distribution on its outstanding shares of Common Stock in shares of
          Common Stock, (ii) subdivide or reclassify its outstanding shares of
          Common Stock into a greater number of shares, or (iii) combine or
          reclassify its outstanding shares of Common Stock into a smaller
          number of shares, the Exercise Price in effect at the time of the
          record date for such dividend or distribution or of the effective date
          of such subdivision, combination or reclassification shall be adjusted
          so that it shall equal the price determined by multiplying the
          Exercise Price by a fraction, the denominator of which shall be the
          number of shares of Common Stock outstanding after giving effect to
          such action, and the numerator of which shall be the number of shares
          of Common Stock outstanding immediately prior to such action. Such
          adjustment shall be made successively whenever any event listed above
          shall occur.

ii.            In case the Company shall fix a record date for the issuance of
          rights or warrants to all holders of its Common Stock entitling them
          to subscribe for or purchase shares of Common Stock (or securities
          convertible into Common Stock) at a price (the "Subscription Price")
          (or
<PAGE>

          having a conversion price per share) less than the Exercise Price on
          the record date mentioned below, the Exercise Price shall be adjusted
          so that the same shall equal the price determined by multiplying the
          Exercise Price in effect immediately prior to the date of issuance by
          a fraction, the numerator of which shall be the sum of the number of
          shares outstanding on the record date mentioned below and the number
          of additional shares of Common Stock which the aggregate offering
          price of the total number of shares of Common Stock so offered (or the
          aggregate conversion price of the convertible securities so offered)
          would purchase at the Exercise Price in effect immediately prior to
          the date of such issuance, and the denominator of which shall be the
          sum of the number of shares of Common Stock outstanding on the record
          date mentioned below and the number of additional shares of Common
          Stock offered for subscription or purchase (or into which the
          convertible securities so offered are convertible). Such adjustment
          shall be made successively whenever such rights or warrants are issued
          and shall become effective immediately after the record date for the
          determination of shareholders entitled to receive such rights or
          warrants; and to the extent that shares of Common Stock are not
          delivered (or securities convertible into Common Stock are not
          delivered) after the expiration of such rights or warrants the
          Exercise Price shall be readjusted to the Exercise Price which would
          then be in effect had the adjustments made upon the issuance of such
          rights or warrants been made upon the basis of delivery of only the
          number of shares of Common Stock (or securities convertible into
          Common Stock) actually delivered.

 iii.          In case the Company shall hereafter distribute to the holders of
          its Common Stock evidences of its indebtedness or assets (excluding
          cash dividends or distributions and dividends or distributions
          referred to in Subsection (1) above) or subscription rights or
          warrants (excluding those referred to in Subsection (2) above), then
          in each such case the Exercise Price in effect thereafter shall be
          determined by multiplying the Exercise Price in effect immediately
          prior thereto by a fraction, the numerator of which shall be the total
          number of shares of Common Stock outstanding multiplied by the Fair
          Market Value per share of Common Stock, less the fair market value (as
          determined by the Company's Board of Directors) of said assets or
          evidences of indebtedness so distributed or of such rights or
          warrants, and the denominator of which shall be the total number of
          shares of Common Stock outstanding multiplied by the Fair Market Value
          per share of Common Stock. Such adjustment shall be made successively
          whenever such a record date is fixed. Such adjustment shall be made
          whenever any such distribution is made and shall become effective
          immediately after the record date for the determination of
          shareholders entitled to receive such distribution.
<PAGE>

  iv.          Whenever the Exercise Price payable upon exercise of each Warrant
          is adjusted pursuant to Subsections (1), (2) or (3) above, the number
          of Shares purchasable upon exercise of this Warrant shall
          simultaneously be adjusted by multiplying the number of Shares
          initially issuable upon exercise of this Warrant by the Exercise Price
          in effect on the date hereof and dividing the product so obtained by
          the Exercise Price, as adjusted.

   v.          No adjustment in the Exercise Price shall be required unless such
          adjustment would require an increase or decrease of at least 5% in
          such price; provided, however, that any adjustments which by reason of
          this Subsection (5) are not required to be made shall be carried
          forward and taken into account in any subsequent adjustment required
          to be made hereunder. All calculations under this Section (f) shall be
          made to the nearest cent or to the nearest one-hundredth of a share,
          as the case may be. Anything in this Section (f) to the contrary
          notwithstanding, the Company shall be entitled, but shall not be
          required, to make such changes in the Exercise Price, in addition to
          those required by this Section (f), as it shall determine, in its sole
          discretion, to be advisable in order that any dividend or distribution
          in shares of Common Stock, or any subdivision, reclassification or
          combination of Common Stock, hereafter made by the Company shall not
          result in any Federal Income tax liability to the holders of Common
          Stock or securities convertible into Common Stock (including
          Warrants).

  vi.          Whenever the Exercise Price is adjusted, as herein provided, the
          Company shall promptly but no later than 10 days after any request for
          such an adjustment by the Holder, cause a notice setting forth the
          adjusted Exercise Price and adjusted number of Shares issuable upon
          exercise of each Warrant, and, if requested, information describing
          the transactions giving rise to such adjustments, to be mailed to the
          Holders at their last addresses appearing in the Warrant Register, and
          shall cause a certified copy thereof to be mailed to its transfer
          agent, if any. The Company may retain a firm of independent certified
          public accountants selected by the Board of Directors (who may be the
          regular accountants employed by the Company) to make any computation
          required by this Section (f), and a certificate signed by such firm
          shall be conclusive evidence of the correctness of such adjustment.


 vii.          In the event that at any time, as a result of an adjustment made
          pursuant to Subsection (1) above, the Holder of this Warrant
          thereafter shall become entitled to receive any shares of the Company,
          other than Common Stock, thereafter the number of such other shares so
          receivable upon exercise of this Warrant shall be subject to
          adjustment from time to time in a manner and on terms as nearly
          equivalent as practicable to the
<PAGE>

               provisions with respect to the Common Stock contained in
               Subsections (1) to (6), inclusive above.

     viii.         Irrespective of any adjustments in the Exercise Price or the
               number or kind of shares purchasable upon exercise of this
               Warrant, Warrants theretofore or thereafter issued may continue
               to express the same price and number and kind of shares as are
               stated in the similar Warrants initially issuable pursuant to the
               Agreement.

g.             OFFICER'S CERTIFICATE. Whenever the Exercise Price shall be
     adjusted as required by the provisions of the foregoing Section, the
     Company shall forthwith file in the custody of its Secretary or an
     Assistant Secretary at its principal office and with its stock transfer
     agent, if any, an officer's certificate showing the adjusted Exercise Price
     determined as herein provided, setting forth in reasonable detail the facts
     requiring such adjustment, including a statement of the number of
     additional shares of Common Stock, if any, and such other facts as shall be
     necessary to show the reason for and the manner of computing such
     adjustment. Each such officer's certificate shall be made available at all
     reasonable times for inspection by the holder or any holder of a Warrant
     executed and delivered pursuant to Section (a) and the Company shall,
     forthwith after each such adjustment, mail a copy by certified mail of such
     certificate to the Holder or any such holder.

h.             NOTICES TO WARRANT HOLDERS. So long as this Warrant shall be
     outstanding, (i) if the Company shall pay any dividend or make any
     distribution upon the Common Stock or (ii) if the Company shall offer to
     the holders of Common Stock for subscription or purchase by them any share
     of any class or any other rights or (iii) if any capital reorganization of
     the Company, reclassification of the capital stock of the Company,
     consolidation or merger of the Company with or into another corporation,
     sale, lease or transfer of all or substantially all of the property and
     assets of the Company to another corporation, or voluntary or involuntary
     dissolution, liquidation or winding up of the Company shall be effected,
     then in any such case, the Company shall cause to be mailed by certified
     mail to the Holder, at least fifteen days prior to the date specified in
     (x) or (y) below, as the case may be, a notice containing a brief
     description of the proposed action and stating the date on which (x) a
     record is to be taken for the purpose of such dividend, distribution or
     rights, or (y) such reclassification, reorganization, consolidation,
     merger, conveyance, lease, dissolution, liquidation or winding up is to
     take place and the date, if any is to be fixed, as of which the holders of
     Common Stock or other securities shall receive cash or other property
     deliverable upon such reclassification, reorganization, consolidation,
     merger, conveyance, dissolution, liquidation or winding up.

i.             RECLASSIFICATION, REORGANIZATION OR MERGER. In case of any
     reclassification, capital reorganization or other change of outstanding
     shares of Common Stock of the Company, or in case of any consolidation or
     merger of
<PAGE>

     the Company with or into another corporation (other than a merger with a
     subsidiary in which merger the Company is the continuing corporation and
     which does not result in any reclassification, capital reorganization or
     other change of outstanding shares of Common Stock of the class issuable
     upon exercise of this Warrant) or in case of any sale, lease or conveyance
     to another corporation of the property of the Company as an entirety, the
     Company shall, as a condition precedent to such transaction, cause
     effective provisions to be made so that the Holder shall have the right
     thereafter by exercising this Warrant at any time prior to the expiration
     of the Warrant, to purchase the kind and amount of shares of stock and
     other securities and property receivable upon such reclassification,
     capital reorganization and other change, consolidation, merger, sale or
     conveyance by a holder of the number of shares of Common Stock which might
     have been purchased upon exercise of this Warrant immediately prior to such
     reclassification, change, consolidation, merger, sale or conveyance. Any
     such provision shall include provision for adjustments which shall be as
     nearly equivalent as may be practicable to the adjustments provided for in
     this Warrant. The foregoing provisions of this Section (i) shall similarly
     apply to successive reclassifications, capital reorganizations and changes
     of shares of Common Stock and to successive consolidations, mergers, sales
     or conveyances. In the event that in connection with any such capital
     reorganization or reclassification, consolidation, merger, sale or
     conveyance, additional shares of Common Stock shall be issued in exchange,
     conversion, substitution or payment, in whole or in part, for a security of
     the Company other than Common Stock, any such issue shall be treated as an
     issue of Common Stock covered by the provisions of Subsection (1) of
     Section (f) hereof.

j.        REGISTRATION UNDER THE SECURITIES ACT OF 1933. Pursuant to the
     Stockholders' Agreement, the Warrant Shares are deemed to be Registrable
     Securities for purposes of Section 6 of the Stockholders' Agreement which
     grants certain registration rights to Holders (as defined in the
     Stockholders' Agreement) of Registrable Securities.
