                          To Purchase Common Stock of

             3-DIMENSIONAL PHARMACEUTICALS, INC.  (the "Company")

                   DATE OF INITIAL ISSUANCE:  June 12, 1997

     THIS CERTIFIES THAT for value received, TRANSAMERICA BUSINESS CREDIT

value, of the Company (the "Common Stock"), at the Warrant Price, payable as
provided herein.  The exercise of this Warrant shall be subject to the
provisions, limitation and restrictions herein contained, and may be exercised
in whole or in part.

<PAGE>

  Warrant Shares - shall mean shares of Common Stock purchased or purchasable by
  --------------
the Holder of this Warrant upon the exercise hereof.

SECTION 2.  EXERCISE OF WARRANT.

     (i)    Procedure for Exercise of Warrant. To exercise this Warrant in whole
or in part (but not as to any fractional share of Common Stock), the Holder
shall deliver to the Company at its office referred to in Section 12 hereof at
any time and from time to time during the Term of this Warrant: (i) the Notice
of Exercise in the form attached hereto, (ii) cash, certified or official bank
check payable to the order of the Company, wire transfer of funds to the
Company's account, or evidence of any indebtedness of the Company to the Holder
(or any combination of any of the foregoing) in the amount of the Warrant Price
for each share being purchased, and (iii) this Warrant. Notwithstanding any
provisions herein to the contrary, if the Current Market Price (as defined in
Section 5) is greater than the Warrant Price (at the date of calculation, as set
forth below), in lieu of exercising this Warrant as hereinabove permitted, the
Holder may elect to receive shares of Common Stock equal to the value (as
determined below) of this Warrant (or the portion thereof being canceled) by
surrender of this Warrant at the office of the Company referred to in Section 12
hereof, together with the Notice of Exercise, in which event the Company shall
issue to the Holder that number of shares of Common Stock computed using the
following formula:


                               CS=WCS x (CMP-WP)
                                  --------------
                                      CMP

Where

  CS    equals the number of shares of Common Stock to be issued to the Holder

  WCS   equals the number of shares of Common Stock purchasable under the
        Warrant or, if only a portion of the Warrant is being exercised,
        the portion of the Warrant being exercised (at the date of such
        calculation)

  CMP   equal the Current Market Price (at the date of such calculation)

  WP    equals the Warrant Price (as adjusted to the date of such calculation)


In the event of any exercise of the rights represented by this Warrant, a
certificate or certificates for the shares of Common Stock so purchased,
registered in the name of the Holder or such other name or names as may be
designated by the Holder, shall be delivered to the Holder hereof within a
reasonable time, not exceeding fifteen (15) days, after the rights represented
by this Warrant shall have been so exercised; and, unless this Warrant has
expired, a new Warrant representing the number of shares (except a remaining
fractional share), if any, with respect to which this Warrant shall not then
have been exercised shall also be issued to the Holder hereof within such time.
The person in whose name any certificate for shares of Common Stock is issued
upon exercise of this Warrant shall for all purposes be deemed to have become
the holder of record of such shares on the date on which the Warrant was
surrendered and payment of the Warrant Price and any applicable taxes was made,
irrespective of the date of delivery of such certificate, except that, if the
date of such surrender and payment is a date when the stock transfer books of
the Company are closed, such person shall be deemed to have become the holder of
such shares at the close of business on the next succeeding date on which the
stock transfer books are open.

  2.2  Transfer Restriction Legend.  Each certificate for Warrant Shares shall
bear the following legend (and any additional legend required by (i) any
applicable state securities laws and (ii)
<PAGE>

any securities exchange upon which such Warrant Shares may, at the time of such
exercise, be listed) on the face thereof unless at the time of exercise such
Warrant Shares shall be registered under the Securities Act:

     "The share represented by this certificate have not been registered under
     the Securities Act of 1933, as amended, or any state securities laws and
     may not be sold or transferred in the absence of such registration or an
     exemption therefrom under said Act and any applicable state securities
     laws."

Any certificate issued at any time in exchange or substitution for any
certificate bearing such legend (except a new certificate issued upon completion
of a public distribution under a registration statement of the securities
represented thereby) shall also bear such legend unless, in the opinion of
counsel for the holder thereof (which counsel shall be reasonably satisfactory
to counsel for the Company) the securities represented thereby are not, at such
time, required by law to bear such legend.

SECTION 3.  COVENANTS AS TO COMMON STOCK.  The Company covenants and agrees that
all shares of Common Stock that may be issued upon the exercise of the rights
represented by this Warrant will, upon issuance, be validly issued, fully paid
and nonassessable, and free from all taxes, liens and charges with respect to
the issue thereof.  The Company further covenants and agrees that it will pay
when due and payable any and all federal and state taxes which may be payable in
respect of the issue of this Warrant or any Common Stock or certificates
therefor issuable upon the exercise of this Warrant.  The Company further
covenants and agrees that the Company will at all times have authorized and
reserved, free from preemptive rights, a sufficient number of shares of Common
Stock to provide for the exercise of the rights represented by this Warrant.
The Company further covenants and agrees that if any shares of capital stock to
be reserved for the purpose of the issuance of shares upon the exercise of this
Warrant require registration with or approval of any governmental authority
under any federal or state law before such shares may be validly issued or
delivered upon exercise, then the Company will in good faith and as
expeditiously as possible endeavor to secure such registration or approval, as
the case may be.  If and so long as the Common Stock issuable upon the exercise
of this Warrant is listed on any national securities exchange, the Company will,
if permitted by the rules of such exchange, list and keep listed on such
exchange, upon the official notice of issuance, all shares of such Common Stock
issuable upon exercise of this Warrant.

SECTION 4.  ADJUSTMENT OF NUMBER OF SHARES.  Upon each adjustment of the Warrant
Price as provided in Section 5, the Holder shall thereafter be entitled to
purchase, at the Warrant Price resulting from such adjustment, the number of
shares (calculated to the nearest tenth of a share) obtained by multiplying the
Warrant Price in effect immediately prior to such adjustment by the number of
shares purchasable pursuant hereto immediately prior to such adjustment and
dividing the product thereof by the Warrant Price resulting from such
adjustment.

SECTION 5.  ADJUSTMENT OF WARRANT PRICE.  The Warrant Price shall be subject to
adjustment from time to time as follows:

      (i) If, at any time during the Term of this Warrant, the number of shares
of Common Stock outstanding is increased by a stock dividend payable in shares
of Common Stock or by a subdivision or split-up of shares of Common Stock, then,
following the record date fixed for the determination of holder of Common Stock
entitled to receive such stock dividend, subdivision or split-up, the Warrant
Price shall be appropriately decreased so that the number of shares of Common
Stock issuable upon the exercise hereof shall be increased in proportion to such
increase in outstanding shares.
<PAGE>

      (ii) If, at any time during the Term of this Warrant, the number of shares
of Common Stock outstanding is decreased by a combination of the outstanding
shares of Common Stock, then, following the record date for such combination,
the Warrant Price shall appropriately increase so that the number of shares of
Common Stock issuable upon the exercise hereof shall be decreased in proportion
to such decrease in outstanding shares.

      (iii)  In case, at any time during the Term of this Warrant, the Company
shall declare a cash dividend upon its Common Stock payable otherwise than out
of earnings or earned surplus or shall distribute to holder of its Common Stock
shares of its capital stock (other than Common Stock), stock or other securities
of other persons, evidences of indebtedness issued by the Company or other
persons, assets (excluding cash dividends and distributions) or options or
rights (excluding options to purchase and rights to subscribe for Common Stock
or other securities of the Company convertible into or exchangeable for Common
Stock), then, in each such case, immediately following the record date fixed for
the determination of the holders of Common Stock entitled to receive such
dividend or distribution, the Warrant Price in effect thereafter shall be
determined by multiplying the Warrant Price in effect immediately prior to such
record date by a fraction of which the numerator shall be an amount equal to the
difference of (x) the Current Market Price of one share of Common Stock minus
(y) the fair market value (as determined by the Board of Directors of the
Company, whose determination shall be conclusive) of the stock, securities,
evidences of indebtedness, assets, options or rights so distributed in respect
of one share of Common Stock, and of which the denominator shall be such Current
Market Price.

      (iv) All calculations under this Section 5 shall be made to the nearest
cent or to the nearest one-tenth (1/10) of a share, as the case may be.

      (v) For the purpose of any computation pursuant to this Section 5, the
Current Market Price at any date of one share of Common Stock shall be deemed to
be the average of the daily closing prices for the 15 consecutive business days
ending no more than 5 business days before the day in question (as adjusted for
any stock dividend, split, combination or reclassification that took effect
during such 15 business day period). The closing price for each day shall be the
last reported bid and asked priced regular way, in either case on the principal
national securities exchange on which the Common Stock is listed or admitted to
trading or as reported by Nasdaq (or if the Common Stock is not at the time
listed or admitted for trading on any such exchange or if prices of the Common
Stock are not reported by Nasdaq then such price shall be equal to the average
of the last reported bid and asked prices on such day as reported by The
National Quotation Bureau Incorporated or any similar reputable quotation and
reporting service, if such quotation is not reported by the National Quotation
Bureau Incorporated); provided, however, that if the Common Stock is not traded
in such manner that the quotations referred to in this clause (v) are available
for the period required hereunder, the Current Market Price shall be determined
in good faith by the Board of Directors of the Company or, if such determination
cannot be made, by a nationally recognized independent investment banking firm
selected by the Board of Directors of the Company (or if such selection cannot
be made, by a nationally recognized independent investment banking firm selected
by the American Arbitration Association in accordance with its rules).

      (vi) Whenever the Warrant Price shall be adjusted as provided in Section
5, the Company shall prepare a statement showing the facts requiring such
adjustment and the Warrant Price that shall be in effect after such adjustment.
The Company shall cause a copy of such statement to be sent by mail, first class
postage prepaid, to each Holder of this Warrant at its, his or her address
appearing on the Company's records. Where appropriate, such copy may be given in
advance and may be included as part of the notice required to be mailed under
the provisions of subsection (viii) of this Section 5.

      (vii) Adjustments made pursuant to clauses (i), (ii) and (iii) above shall
be made on the date such divided, subdivision, split-up, combination or
distribution, as the case may be, is made, and shall
<PAGE>

become effective at the opening of business on the business day next following
the record date for the determination of stockholders entitled to such dividend,
subdivision, split-up, combination or distribution.

      (viii) In the event the Company shall propose to take any action of the
types described in clauses (i), (ii), or (iii) of this Section 5, the Company
shall forward, at the same time and in the same manner, to the Holder of this
Warrant such notice, if any , which the Company shall give to the holders of
capital stock of the Company.

      (ix) In any case in which the provisions of this Section 5 shall require
that an adjustment shall become effective immediately after a record date for an
event, the Company may defer until the occurrence of such event issuing to the
Holder of all or any part of this Warrant which is exercised after such record
date and before the occurrence of such event the additional shares of capital
stock issuable upon such exercise by reason of the adjustment required by such
event over and above the shares of capital stock issuable upon such exercise
before giving effect to such adjustment exercise; provided, however, that the
Company shall deliver to such Holder a due bull or other appropriate instrument
evidencing such Holder's right to receive such additional shares upon the
occurrence of the event requiring such adjustment.

SECTION 6.  OWNERSHIP.

     6.1    Ownership of This Warrant. The Company may deem and treat the person
in whose name this Warrant is registered as the holder and owner hereof
(notwithstanding any notations of ownership or writing hereon made by anyone
other than the Company) for all purposes and shall not be affected by any notice
to the contrary until presentation of this Warrant for registration of transfer
as provided in this Section 6.

     6.2    Transfer and Replacement.  (i)  Subject to the restrictions provided
herein, this Warrant and all rights hereunder are transferable in whole or in
part upon the books of the Company by the Holder hereof in person or by duly
authorized attorney, and a new Warrant or Warrants, of the same tenor as this
Warrant but registered in the name of the transferee or transferees (and in the
name of the Holder, if a partial transfer is effected) shall be made and
delivered by the Company upon surrender of this Warrant duly endorsed, at the
office of the Company referred to in Section 12 hereof. Upon receipt by the
Company of evidence reasonably satisfactory to it of the loss, theft or
destruction, and, in such case, of indemnity or security reasonably satisfactory
to it, and upon surrender of this Warrant if mutilated, the Company will make
and deliver a new Warrant of like tenor, in lieu of this Warrant; provided that
if the Holder hereof is an instrumentality of a state or local government or an
institutional holder or a nominee for such an instrumentality or institutional
holder an irrevocable agreement of indemnity by such Holder shall be sufficient
for all purposes of this Section 6, and no evidence of loss or theft or
destruction shall be necessary. This Warrant shall be promptly canceled by the
Company upon the surrender hereof if connection with any transfer or
replacement. Except as otherwise provided above, in the case of the loss, theft
or destruction of a Warrant, the Company shall pay all expenses, taxes and other
charges payable in connection with any transfer or replacement of this Warrant,
other than stock transfer taxes (if any) payable in connection with a transfer
of this Warrant, which shall be payable by the Holder.

      (ii) The transferability of this Warrant and the Warrant Shares are
subject to the following restrictions:

           (a) Registration Restrictions. This Warrant and the Warrant Shares
               -------------------------
have not been registered under the Securities Act by reason of their issuance in
a transaction exempt from the registration requirements of the Securities Act
pursuant to the exemption provided in Section 4(2) thereof,
<PAGE>

and have not been registered under state securities laws by reason or their
issuance in a transaction exempt from such registration requirements. This
Warrant and the Warrant Shares may not be offered for sale, sold, transferred or
otherwise disposed of unless registered under the Securities Act and applicable
state securities laws or exempted from registration. The Company shall be
entitled to give stop transfer instructions to the transfer agent with respect
to the Warrant and the Warrant Shares in order to enforce the foregoing
restriction. The restrictions contained herein shall be binding on any
transferee of this Warrant and the Company may require any such transferee to
execute an instrument agreeing in writing to be so bound by these restrictions
as a condition to transfer.

           (b)  Notice of Transfer and Opinion of Counsel.  The Holder,
                -----------------------------------------
and any other holder of the Warrant by acceptance thereof, agrees that, prior to
any transfer of any Warrant, such holder will give written notice to the Company
of such holder's intention to effect such transfer and to comply in all other
respects with the provisions of this Section 6.2. Each such notice shall contain
(I) a statement setting such Warrant, and (II) unless waived by the Company, an
opinion of counsel for such holder (who may be the inside or staff counsel
employed by such holder), as tot he necessity or non-necessity for registration
under the Securities Act and applicable state securities laws in connection with
such transfer and stating the factual and statutory bases relied upon by
counsel. The following provisions shall then apply:

           (I)  If in the opinion of counsel for the Company the proposed
transfer of such Warrant may be effected without registration or qualification
under the Securities Act and any applicable state securities laws, then the
registration holder of such Warrant shall be entitled to transfer such Warrant
in accordance with the intended method of disposition specified in the statement
delivered by such holder to the Company.

           (II) In the opinion of counsel for the Company the proposed transfer
of such Warrant may not be effected without registration under the Securities
Act or registration or qualification under any applicable state securities laws,
the registered holder of such Warrant shall not be entitled to transfer such
Warrant until the requisite registration or qualification is effective.

SECTION 7.  Mergers, Consolidation, Sales.  In the case of any proposed
            -----------------------------
consolidation or merger of the Company with another entity, or the proposed sale
of all or substantially all of its assets to another person or entity, or any
proposed reorganization or reclassification of the capital stock of the Company
adequate provision shall be made whereby the Holder of this Warrant shall
thereafter have the right to receive upon the basis and upon the terms and
conditions specified herein, in lieu of the shares of the Common Stock of the
Company immediately theretofore purchasable hereunder, such shares of stock,
securities or assets as may (by virtue of such consolidation, merger, sale,
reorganization or reclassification) be issued or payable with respect to or in
exchange for the number of shares of such Common Stock purchasable hereunder
immediately before such consolidation, merger, sale, reorganization or
reclassification.  In any such case appropriate provision shall be made with
respect to the rights and interests of the Holder of this Warrant to the end
that the provisions hereof shall thereafter be applicable as nearly as may be,
in relation to any shares of stock, securities or assets thereafter deliverable
upon the exercise of this Warrant.

SECTION 8.  Notice of Dissolution or Liquidation.  In case of any distribution
            ------------------------------------
of the assets of the Company in dissolution or liquidation (except under
circumstances when the foregoing Section 7 shall be applicable), the Company
shall give notice thereof to the Holder hereof and shall make no distribution to
shareholders until the expiration of thirty (30) days from the date of mailing
of the aforesaid notice and, in any case, the Holder hereof may exercise this
Warrant within thirty (30) days from the date of the giving of such notice, and
all rights herein granted not so exercised within such thirty-day period shall
thereafter become null and void.
<PAGE>

SECTION 9.  Notice of Extraordinary Dividends.  If the Board of Directors of the
            ---------------------------------
Company shall declare any dividend or other distribution on its Common Stock
except out of earned surplus or by way of a stock dividend payable in shares of
its Common Stock, the Company shall mail notice thereof to the Holder hereof not
less than thirty (30) days prior to the record date fixed for determining
shareholders entitled to participate in such dividend or other distribution, and
the Holder hereof shall not participate in such dividend or other distribution
unless this Warrant is exercised prior to such record date.  The provisions of
this Section 9 shall not apply to distributions made in connection with
transactions covered by Section 7.

SECTION 10.  Fractional Shares.  Fractional shares shall not be issued upon the
             -----------------
exercise of this Warrant but in any case where the Holder would, except for the
provisions of this Section 10, be entitled under the terms hereof to receive a
fractional share upon the complete exercise of this Warrant, the Company shall,
upon the exercise of this Warrant for the largest number of whole shares then
called for, pay a sum in cash equal to the excess of the value of such
fractional share (determined in such reasonable manner as may be prescribed in
good faith by the Board of Directors of the Company) over the Warrant Price for
such fractional share.

SECTION 11.  Special Arrangements of the Company.  The Company covenants and
             -----------------------------------
agrees that during the Term of this Warrant, unless otherwise approved by the
Holder of this Warrant:

       11.1  Will Reserve Shares.  The Company will reserve and set apart

consolidation or acquisition of all or substantially all of the Company's
assets.
