                          COMMON STOCK PURCHASE WARRANT

Warrant No. 1                                                     100,000 shares

                       Original Issue Date: March 16, 1999

     THIS CERTIFIES THAT, FOR VALUE RECEIVED, SOVCAP EQUITY PARTNERS, LTD. or
its assigns (the "Holder") is entitled to purchase, on the terms and conditions
hereinafter set forth, at any time or from time to time from the date hereof
until 5:00 p.m., Eastern Time, on the fifth (5th) anniversary of the Original
Issue Date set forth above, or if such date is not a day on which the Company is
open for business, then the next succeeding day on which the Company is open for
business (such date is the "Expiration Date"), but not thereafter, up to ONE
HUNDRED THOUSAND (100,000) shares of the Common Stock, par value $.01 (the
"Common Stock"), of COMPOSITECH LTD., a Delaware corporation (the "Company"), at
a price of $.____ {110% of Closing Bid Price on Original Issue Date} per share
(the "Exercise Price"), such number of shares and Exercise Price being subject
to adjustment upon the occurrence of the contingencies set forth in this
Warrant. Each share of Common Stock as to which this Warrant is exercisable is a
"Warrant Share" and all such shares are collectively referred to as the "Warrant
Shares."

     Section 1. Exercise of Warrant; Conversion of Warrant.

     (a) This Warrant may, at the option of the Holder, be exercised in whole or
in part from time to time by delivery to the Company at its office at 120
Ricefield Lane, Hauppauge, New York 11788, Attention: President, or to any
transfer agent for the Common Stock, on or before 5:00 p.m., Eastern Time, on
the Expiration Date, (i) a written notice of such registered Holder's election
to exercise this Warrant (the "Exercise Notice"), which notice may be in the
form of the Notice of Exercise attached hereto, properly executed and completed
by the registered Holder or an authorized officer thereof, (ii) a check payable
to the order of the Company, in an amount equal to the product of the Exercise
Price multiplied by the number of Warrant Shares specified in the Exercise
Notice, and (iii) this Warrant (the items specified in (i), (ii), and (iii) are
collectively the "Exercise Materials").

     (b) Upon timely receipt of the Exercise Materials, the Company shall, as
promptly as practicable, and in any event within five (5) business days after
its receipt of the Exercise Materials, execute or cause to be executed and
delivered to Holder a certificate or certificates representing the number of
Warrant Shares specified in the Exercise Notice, together with cash in lieu of
any fraction of a share, and, (x) if the Warrant is exercised in full, a copy of
this Warrant marked "Exercised," or (y) if the Warrant is partially exercised, a
copy of this Warrant marked "Partially Exercised" together with a new Warrant on
the same terms for the unexercised balance of the Warrant Shares, or (z) if the
Warrant is converted, a copy of this Warrant marked "Converted." The stock
certificate or certificates shall be registered in the name of the registered



                                      -1-
<PAGE>


Holder of this Warrant or such other name or names as shall be designated in the
Exercise Notice or Conversion Notice. The date on which the Warrant shall be
deemed to have been exercised or converted (the "Effective Date"), and the date
the person in whose name any certificate evidencing the Common Stock issued upon
the exercise or conversion hereof is issued shall be deemed to have become the
holder of record of such shares, shall be the date the Corporation receives the
Exercise Materials, irrespective of the date of delivery of a certificate or
certificates evidencing the Common Stock issued upon the exercise or conversion
hereof, except that, if the date on which the Exercise Materials are received by
the Company is a date on which the stock transfer books of the Company are
closed, the Effective Date shall be the date the Company receives the Exercise
Materials, and the date such person shall be deemed to have become the holder of
the Common Stock issued upon the exercise or conversion hereof shall be the next
succeeding date on which the stock transfer books are open. All shares of Common
Stock issued upon the exercise or conversion of this Warrant will, upon
issuance, be fully paid and nonassessable and free from all taxes, liens, and
charges with respect thereto.

     (c) If the Company shall fail to issue to Holder within five (5) business
days following the Effective Date a certificate for the number of shares of
Common Stock to which such holder is entitled upon such holder's exercise or
conversion of this Warrant, in addition to all other available remedies which
such holder may pursue hereunder and the Series 1 Bridge Note Purchase and
Security Agreement between the Company and the initial holder of the Warrant
(the "Securities Purchase Agreement") including indemnification pursuant to
Section 7.18 thereof (all of which shall be cumulative), the Company shall pay
additional damages to such holder on each day after the Effective Date, an
amount equal to 1.0% of the product of (A) the number of Warrant Shares not
issued to Holder and to which Holder is entitled multiplied by (B) the Closing
Bid Price of the Common Stock on the Effective Date. Such damages shall be
computed daily and are due and payable daily. Additionally, notwithstanding
anything in this Section 1 to the contrary, Holder may withdraw an Exercise
Notice at any time prior to Holder's receipt of certificates evidencing the
Warrant Shares if Holder has otherwise complied with the requirements of this
Section 1.

     Section 2. Adjustments to Warrant Shares. The number of Warrant Shares
issuable upon the exercise hereof shall be subject to adjustment as follows:

          (a) In the event the Company is a party to a consolidation, share
     exchange, or merger, or the sale of all or substantially all of the assets
     of the Company to, any person, or in the case of any consolidation or
     merger of another corporation into the Company in which the Company is the
     surviving corporation, and in which there is a reclassification or change
     of the shares of Common Stock of the Company, this Warrant shall after such
     consolidation, share exchange, merger, or sale be exercisable for the kind
     and number of securities or amount and kind of property of the Company or
     the corporation or other entity resulting from such share exchange, merger,
     or consolidation, or to which such sale shall be made, as the case may be
     (the "Successor Company"), to which a holder of the number of shares of
     Common Stock deliverable upon the exercise (immediately prior to the time
     of such consolidation, share exchange, merger, or sale) of this Warrant
     would have been entitled upon such consolidation, share exchange, merger,
     or sale; and in any such case appropriate adjustments shall be made in the
     application of the provisions set forth herein with respect to the rights
     and interests of the registered Holder of this Warrant, such that the
     provisions set forth herein shall thereafter correspondingly be made
     applicable, as nearly as may reasonably be, in relation to the number and
     kind of securities or the type and amount of property thereafter
     deliverable upon the exercise of this Warrant. The above provisions shall
     similarly apply to successive consolidations, share



                                      -2-
<PAGE>


     exchanges, mergers, and sales. Any adjustment required by this Section 2
     (a) because of a consolidation, share exchange, merger, or sale shall be
     set forth in an undertaking delivered to the registered Holder of this
     Warrant and executed by the Successor Company which provides that the
     Holder of this Warrant shall have the right to exercise this Warrant for
     the kind and number of securities or amount and kind of property of the
     Successor Company or to which the holder of a number of shares of Common
     Stock deliverable upon exercise (immediately prior to the time of such
     consolidation, share exchange, merger, or sale) of this Warrant would have
     been entitled upon such consolidation, share exchange, merger, or sale.
     Such undertaking shall also provide for future adjustments to the number of
     Warrant Shares and the Exercise Price in accordance with the provisions set
     forth in Section 2 hereof.

          (b) In the event the Company should at any time, or from time to time
     after the Original Issue Date, fix a record date for the effectuation of a
     stock split or subdivision of the outstanding shares of Common Stock or the
     determination of holders of Common Stock entitled to receive a dividend or
     other distribution payable in additional shares of Common Stock, or
     securities or rights convertible into, or entitling the holder thereof to
     receive directly or indirectly, additional shares of Common Stock
     (hereinafter referred to as "Common Stock Equivalents") without payment of
     any consideration by such holder for the additional shares of Common Stock
     or the Common Stock Equivalents (including the additional shares of Common
     Stock issuable upon exercise or exercise thereof), then, as of such record
     date (or the date of such dividend, distribution, split, or subdivision if
     no record date is fixed), the number of Warrant Shares issuable upon the
     exercise hereof shall be proportionately increased and the Exercise Price
     shall be appropriately decreased by the same proportion as the increase in
     the number of outstanding Common Stock Equivalents of the Company resulting
     from the dividend, distribution, split, or subdivision. Notwithstanding the
     preceding sentence, no adjustment shall be made to decrease the Exercise
     Price below $.01 per Share.

          (c) In the event the Company should at any time or from time to time
     after the Original Issue Date, fix a record date for the effectuation of a
     reverse stock split, or a transaction having a similar effect on the number
     of outstanding shares of Common Stock of the Company, then, as of such
     record date (or the date of such reverse stock split or similar transaction
     if no record date is fixed), the number of Warrant Shares issuable upon the
     exercise hereof shall be proportionately decreased and the Exercise Price
     shall be appropriately increased by the same proportion as the decrease of
     the number of outstanding Common Stock Equivalents resulting from the
     reverse stock split or similar transaction.

          (d) In the event the Company should at any time or from time to time
     after the Original Issue Date, fix a record date for a reclassification of
     its Common Stock, then, as of such record date (or the date of the
     reclassification if no record date is set), this Warrant shall thereafter
     be convertible into such number and kind of securities as would have been
     issuable as the result of such reclassification to a holder of a number of
     shares of Common Stock equal to the number of Warrant Shares issuable upon
     exercise of this Warrant immediately prior to such reclassification, and
     the Exercise Price shall be unchanged.

          (e) The Company will not, by amendment of its Certificate of
     Incorporation or through reorganization, consolidation, merger,
     dissolution, issue, or sale of securities, sale of assets or any other
     voluntary action, void or seek to avoid the observance or performance of
     any of the terms of the Warrant, but will at all times in good faith assist
     in the carrying out of all such terms and in the taking of all such actions
     as may be necessary or appropriate in order to protect the rights of the
     Holder against dilution or other impairment. Without limiting the
     generality of



                                      -3-
<PAGE>


     the foregoing, the Company (x) will not create a par value of any share of
     stock receivable upon the exercise of the Warrant above the amount payable
     therefor upon such exercise, and (y) will take all such action as may be
     necessary or appropriate in order that the Company may validly and legally
     issue fully paid and non-assessable shares upon the exercise of the
     Warrant.

          (f) When any adjustment is required to be made in the number or kind
     of shares purchasable upon exercise of the Warrant, or in the Exercise
     Price, the Company shall promptly notify the Holder of such event and of
     the number of shares of Common Stock or other securities or property
     thereafter purchasable upon exercise of the Warrants and of the Exercise
     Price, together with the computation resulting in such adjustment.

          (g) The Company covenants and agrees that all Warrant Shares which may
     be issued will, upon issuance, be validly issued, fully paid, and
     non-assessable. 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 its Common Stock to provide for
     the exercise of the Warrant in full.

     Section 3. No Stockholder Rights. This Warrant shall not entitle the Holder
hereof to any voting rights or other rights as a stockholder of the Company.

     Section 4. Transfer of Securities.

     (a) This Warrant and the Warrant Shares and any shares of capital stock
received in respect thereof, whether by reason of a stock split or share
reclassification thereof, a stock dividend thereon, or otherwise, shall not be
transferable except upon compliance with the provisions of the Securities Act of
1933, as amended (the "Securities Act") and applicable state securities laws
with respect to the transfer of such securities. The Holder of this Warrant, by
acceptance of this Warrant, agrees to be bound by the provisions of Section 4
hereof and to indemnify and hold harmless the Company against any loss or
liability arising from the disposition of this Warrant or the Warrant Shares
issuable upon exercise hereof or any interest in either thereof in violation of
the provisions of this Warrant.

     (b) Each certificate for the Warrant Shares and any shares of capital stock
received in respect thereof, whether by reason of a stock split or share
reclassification thereof, a stock dividend thereon or otherwise, and each
certificate for any such securities issued to subsequent transferees of any such
certificate shall (unless otherwise permitted by the provisions hereof) be
stamped or otherwise imprinted with a legend in substantially the following
form:

     TRANSFERRED UNTIL (I) A REGISTRATION STATEMENT UNDER SUCH SECURITIES ACT

     OF COUNSEL ACCEPTABLE TO THE COMPANY TO THE EFFECT THAT REGISTRATION UNDER

benefit of any successors or assigns of the Company and of the holder or holders
hereof and of the Common Stock issued or issuable upon the exercise hereof.
