         WARRANT AGREEMENT, dated as of __________ __, 1997, by and among
DISCAS, INC., a Delaware corporation (the "Company"), AMERICAN STOCK TRANSFER &
TRUST COMPANY, as warrant agent (hereinafter called the "Warrant Agent"), and
ROAN CAPITAL PARTNERS L.P., the representative (the "Representative") of the
several Underwriters (the "Underwriters").

         WHEREAS, the Company proposes to issue and sell, through an initial
public offering by the Underwriters pursuant to an Underwriting Agreement dated
__________ __, 1997, an aggregate of up to 920,000 shares of common stock,
$.0001 par value per share (the "Common Stock"), and up to 920,000 Common Stock
Purchase Warrants (the "Warrants") of the Company; and in connection with such
offering the Company has agreed to issue to the Representative or its designees
an option to purchase 80,000 shares of Common Stock and 80,000 Warrants (the
"Representative's Warrant") and the Company will issue an additional 800,000
Warrants upon the automatic conversion of 800,000 currently existing and
outstanding warrants upon closing of the initial public offering of the
Warrants and the Common Stock;

         WHEREAS, each Warrant will entitle the holder to purchase one share of
Common Stock;

         WHEREAS, the Company desires the Warrant Agent to act on behalf of the
Company, and the Warrant Agent is willing to so act in connection with the
issuance, registration, transfer, exchange and exercise of the Warrants;

         NOW, THEREFORE, in consideration of the premises and the mutual
agreements herein set forth, the parties hereto agree as follows:

         Section 1. Appointment of Warrant Agent. The Company hereby appoints
the Warrant Agent to act as Warrant Agent for the Company in accordance with
the instructions hereinafter set forth in this Agreement, and the Warrant Agent
hereby accepts such appointment.

         Section 2. Form of Warrant. The text of the Warrants and of the form
of election to purchase Common Stock to be printed on the reverse thereof shall
be substantially as set forth in Exhibit A attached hereto. Each Warrant shall
entitle the registered holder thereof to purchase one share of Common Stock at
a purchase price 

                                       1


of $5.00, at any time commencing thirteen (13) months from the effective date
of the prospectus of the public offering (__________ __, 1997) ("Effective
Date") until 5:00 p.m. Eastern time, on __________ __, 2002. The warrant
exercise price and the number of shares of Common Stock issuable upon exercise
of the Warrants are subject to adjustment upon the occurrence of certain
events, all as hereinafter provided. The Warrants shall be executed on behalf
of the Company by the manual or facsimile signature of the present or any
future President or Vice President of the Company, and attested to by the
manual or facsimile signature of the present or any future Secretary or
Assistant Secretary of the Company.

         Warrants shall be dated as of the issuance by the Warrant Agent either
upon initial issuance or upon transfer or exchange.

         In the event the aforesaid expiration dates of the Warrants fall on a
Saturday or Sunday, or on a legal holiday on which the New York Stock Exchange
is closed, then the Warrants shall expire at 5:00 p.m. Eastern time on the next
succeeding business day.

         Section 3. Countersignature and Registration. The Warrant Agent shall
maintain books for the transfer and registration of the Warrants. Upon the
initial issuance of the Warrants, the Warrant Agent shall issue and register
the Warrants in the names of the respective holders thereof. The Warrants shall
be countersigned manually or by facsimile by the Warrant Agent (or by any
successor to the Warrant Agent then acting as warrant agent under this
Agreement) and shall not be valid for any purpose unless so countersigned. The
Warrants may, however, be so countersigned by the Warrant Agent (or by its
successor as Warrant Agent) and be delivered by the Warrant Agent,
notwithstanding that the persons whose manual or facsimile signatures appear
thereon as proper officers of the Company shall have ceased to be such officers
at the time of such countersignature or delivery.

         Section 4. Transfers and Exchanges. The Warrant Agent shall transfer,
from time to time, any outstanding Warrants upon the books to be maintained by
the Warrant Agent for that purpose, upon surrender thereof for transfer
properly endorsed or accompanied by appropriate instructions for transfer. Upon
any such transfer, a new Warrant shall be issued to the transferee and the
surrendered Warrant shall be cancelled by the Warrant Agent. Warrants so
cancelled shall be delivered by the Warrant Agent to the Company

                                       2


from time to time upon request. Warrants may be exchanged at the option of the
holder thereof, when surrendered at the office of the Warrant Agent, for
another Warrant, or other Warrants of different denominations of like tenor and
representing in the aggregate the right to purchase a like number of shares of
Common Stock.

         Section 5. Exercise of Warrants; Payment of Warrant Solicitation Fee.
Subject to the provisions of this Agreement, each registered holder of Warrants
shall have the right, which may be exercised commencing at the opening of the
business on ___________ __, 1998, to purchase from the Company (and the Company
shall issue and sell to such registered holder of Warrants) the number of fully
paid and non-assessable shares of Common Stock specified in such Warrants upon
surrender of such Warrants to the Company at the office of the Warrant Agent,
with the form of election to purchase on the reverse thereof duly filled in and
signed, and upon payment to the Company of the warrant price, determined in
accordance with the provisions of Sections 9 and 10 of this Agreement, for the
number of shares of Common Stock in respect of which such Warrants are then
exercised. Payment of such warrant price shall be made in cash or by certified
check or bank draft to the order of the Company. Subject to Section 6, upon
such surrender of Warrants and payment of the warrant price, the Company shall
issue and cause to be delivered with all reasonable dispatch to or upon the
written order of the registered holder of such Warrants and in such name or
names as such registered holder may designate, a certificate or certificates
for the number of full shares of Common Stock so purchased upon the exercise of
such Warrants. Such certificate or certificates shall be deemed to have been
issued and any person so designated to be named therein shall be deemed to have
become a holder of record of such shares of Common Stock as of the date of the
surrender of such Warrants and payment of the warrant price as aforesaid. The
rights of purchase represented by the Warrants shall be exercisable, at the
election of the registered holders thereof, either as an entirety or from time
to time for a portion of the shares specified therein and, in the event that
any Warrant is exercised in respect of less than all of the shares of Common
Stock specified therein at any time prior to the date of expiration of the
Warrants, a new Warrant or Warrants will be issued to the registered holder for
the remaining number of shares of Common Stock specified in the Warrant so
surrendered, and the Warrant Agent is hereby irrevocably authorized to
countersign and to deliver the required new Warrants pursuant to the provisions
of this Section and of Section 3 of this Agreement and the Company,

                                       3


whenever requested by the Warrant Agent, will supply the Warrant Agent with
Warrants duly executed on behalf of the Company for such purpose. Anything in
the foregoing to the contrary notwithstanding, no Warrant will be exercisable
unless at the time of exercise the Company has filed with the Securities and
Exchange Commission a registration statement under the Securities Act of 1933
(the "Act") covering the shares of Common Stock issuable upon exercise of such
Warrant and such registration statement shall have been declared effective,
such shares have been so registered or qualified or deemed to be exempt under
the securities laws of the state of residence of the holder of such Warrant.
The Company shall use its best efforts to have all shares so registered or
qualified on or before the date on which the Warrants become exercisable.

            (a) If at the time of exercise of any Warrant after __________ __,
1998 (i) the market price of the Company's Common Stock is equal to or greater
than the then exercise price of the Warrant, (ii) the exercise of the Warrant
is solicited by the Underwriter at such time as it is a member of the National
Association of Securities Dealers, Inc. ("NASD"), (iii) the Warrant is not held
in a discretionary account, (iv) disclosure of the compensation arrangement is
made in documents provided to the

                                       4


holders of the Warrants, (v) the Underwriter is designated in writing as the
soliciting broker and (vi) the solicitation of the exercise of the Warrant is
not in violation of Regulation M (as such rule or any successor rule may be in
effect as of such time of exercise) promulgated under the Securities Exchange
Act of 1934, then the Underwriter soliciting such Warrant shall be entitled to
receive from the Company upon exercise of each of the Warrants so exercised a
fee of seven percent (7%) of the aggregate price of the Warrants so exercised
(the "Exercise Fee"). The procedures for payment of the warrant solicitation
fee are set forth in Section 5(b) below.

            (b) (1) Within five (5) days of the last day of each month
commencing with __________ __, 1998, the Warrant Agent will notify the
Representative of each Warrant Certificate which has been properly completed
for exercise by holders of Warrants during the last month. The Company and
Warrant Agent shall determine, in their sole and absolute discretion, whether a
Warrant Certificate has been properly completed. The Warrant Agent will provide
the Representative with such information, in connection with the exercise of
each Warrant, as the Representative shall reasonably request.

                (2) The Company hereby authorizes and instructs the Warrant
Agent to deliver to the soliciting Underwriter the Exercise Fee promptly after
receipt by the Warrant Agent from the Company of a check payable to the order
of the soliciting Underwriter in the amount of the Exercise Fee. In the event
that an Exercise Fee is paid to the Underwriter with respect to a Warrant which
the Company or the Warrant Agent determines is not properly completed for
exercise or in respect of which the Underwriter is not entitled to an Exercise
Fee, the soliciting Underwriter will return such Exercise Fee to the Warrant
Agent which shall forthwith return such fee to the Company.

         The Representative and the Company may at any time after __________
__, 1998, and during business hours, examine the records of the Warrant Agent,
including its ledger of original Warrant certificates returned to the Warrant
Agent upon exercise of Warrants. Notwithstanding any provision to the contrary,
the provisions of paragraph 5(a) and 5(b) may not be modified, amended or
deleted without the prior written consent of the Representative.

                                       5


         Section 6. Payment of Taxes. The Company will pay any documentary
stamp taxes attributable to the initial issuance of Common Stock issuable upon
the exercise of Warrants; provided, however, that the Company shall not be
required to pay any tax which may be payable in respect of any transfer
involved in the issuance or delivery of any certificates of shares of Common
Stock in a name other than that of the registered holder of Warrants in respect
of which such shares are issued, and in such case neither the Company nor the
Warrant Agent shall be required to issue or deliver any certificate for shares
of Common Stock or any Warrant until the person requesting the same has paid to
the Company the amount of such tax or has established to the Company's
satisfaction that such tax has been paid.

         Section 7. Mutilated or Missing Warrants. In case any of the Warrants
shall be mutilated, lost, stolen or destroyed, the Company may, in its
discretion, issue and the Warrant Agent shall countersign and deliver in
exchange and substitution for and upon cancellation of the mutilated Warrant,
or in lieu of and in substitution for the Warrant lost, stolen or destroyed, a
new Warrant of like tenor and representing an equivalent right or interest, but
only upon receipt of evidence satisfactory to the Company and the Warrant Agent
of such loss, theft or destruction and, in case of a lost, stolen or destroyed
Warrant, indemnity, if requested, also satisfactory to them. Applicants for
such substitute Warrants shall also comply with such other reasonable
regulations and pay such reasonable charges as the Company or the Warrant Agent
may prescribe.

         Section 8. Reservation of Common Stock. There have been reserved, and
the Company shall at all times keep reserved, out of the authorized and
unissued shares of Common Stock, a number of shares of Common Stock sufficient
to provide for the exercise of the rights of purchase represented by the
Warrants, and the transfer agent for the shares of Common Stock and every
subsequent transfer agent for any shares of the Company's Common Stock issuable
upon the exercise of any of the rights of purchase aforesaid are irrevocably
authorized and directed at all times to reserve such number of authorized and
unissued shares of Common Stock as shall be required for such purpose. The
Company agrees that all shares of Common Stock issued upon

                                       6


exercise of the Warrants shall be, at the time of delivery of the certificates
of such shares, validly issued and outstanding, fully paid and nonassessable
and listed on any national securities exchange upon which the other shares of
Common Stock are then listed. So long as any unexpired Warrants remain
outstanding, the Company will file such post-effective amendments to the
registration statement (Form SB-2, Registration No. 333 - ______) (the
"Registration Statement") filed pursuant to the Act with respect to the
Warrants (or other appropriate registration statements or post-effective
amendment or supplements) as may be necessary to permit it to deliver to each
person exercising a Warrant, a prospectus meeting the requirements of Section
10(a)(3) of the Act and otherwise complying therewith, and will deliver such
prospectus to each such person. To the extent that during any period it is not
reasonably likely that the Warrants will be exercised, due to market price or
otherwise, the Company need not file such a post-effective amendment during
such period. The Company will keep a copy of this Agreement on file with the
transfer agent for the shares of Common Stock and with every subsequent
transfer agent for any shares of the Company's Common Stock issuable upon the
exercise of the rights of purchase represented by the Warrants. The Warrant
Agent is irrevocably authorized to requisition from time to time from such
transfer agent stock certificates required to honor outstanding Warrants. The
Company will supply such transfer agent with duly executed stock certificates
for that purpose. All Warrants surrendered in the exercise of the rights
thereby evidenced shall be cancelled by the Warrant Agent and shall thereafter
be delivered to the Company, and such cancelled Warrants shall constitute
sufficient evidence of the number of shares of Common Stock which have been
issued upon the exercise of such Warrants. Promptly after the date of
expiration of the Warrants, the Warrant Agent shall certify to the Company the
total aggregate amount of Warrants then outstanding, and thereafter no shares
of Common Stock shall be subject to reservation in respect of such Warrants
which shall have expired.

         Section 9. Warrant Price: Adjustments.

            (a) The warrant price at which Common Stock shall be purchasable
upon the exercise of the Warrants shall be $5.00 at any time from __________
__, 1998 until 5:00 Eastern time on __________ __, 2002 or after adjustment, as
provided in this Section, shall be such price as so adjusted (the "Warrant
Price").

            (b) The Warrant Price shall be subject to adjustment from time to
time as follows:

                                       7


                (i) In case the Company shall at any time after the date hereof
pay a dividend in shares of Common Stock or make a distribution in shares of
Common Stock, then upon such dividend or distribution the Warrant Price in
effect immediately prior to such dividend or distribution shall forthwith be
reduced to a price determined by dividing:

                    (A) an amount equal to the total number of shares of Common
Stock outstanding immediately prior to such dividend or distribution multiplied
by the Warrant Price in effect immediately prior to such dividend or
distribution, by

                    (B) the total number of shares of Common Stock outstanding
immediately after such issuance or sale.

         For the purposes of any computation to be made in accordance with the
provisions of this clause:

                (i) The following provisions shall be applicable: Common Stock
issuable by way of dividend or other distribution on any stock of the Company
shall be deemed to have been issued immediately after the opening of business
on the date following the date fixed for the determination of stockholders
entitled to receive such dividend or other distribution.

                (ii) In case the Company shall at any time subdivide or combine
the outstanding Common Stock, the Warrant Price shall forthwith be
proportionately decreased in the case of subdivision or increased in the case
of combination to the nearest one cent. Any such adjustment shall become
effective at the time such subdivision or combination shall become effective.

                (iii) Within a reasonable time after the close of each
quarterly fiscal period of the Company during which the Warrant Price has been
adjusted as herein provided, the Company shall:

                    (A) File with the Warrant Agent a certificate signed by the
President or Vice President of the Company and by the Treasurer or Assistant
Treasurer or the Secretary or an Assistant Secretary of the Company, showing in
detail the facts requiring all such adjustments occurring during such period
and the Warrant Price after each such adjustment; and

                                       8


                    (B) The Warrant Agent shall have no duty with respect to
any such certificate filed with it except to keep the same on file and
available for inspection by holders of Warrants during reasonable business
hours, and the Warrant Agent may conclusively rely upon the latest certificate
furnished to it hereunder. The Warrant Agent shall not at any time be under any
duty or responsibility to any holder of a Warrant to determine whether any
facts exist which may require any adjustment of the Warrant Price, or with
respect to the nature or extent of any adjustment of the Warrant Price when
made, or with respect to the method employed in making any such adjustment, or
with respect to the nature or extent of the property or securities deliverable
hereunder. In the absence of a certificate having been furnished, the Warrant
Agent may conclusively rely upon the provisions of the Warrants with respect to
the Common Stock deliverable upon the exercise of the Warrants and the
applicable Warrant Price thereof.

                    (C) Notwithstanding anything contained herein to the
contrary, no adjustment of the Warrant Price shall be made if the amount of
such adjustment shall be less than $.05, but in such case any adjustment that
would otherwise be required then to be made shall be carried forward and shall
be made at the time and together with the next subsequent adjustment which,
together with any adjustment so carried forward, shall amount to not less than
$.05.

            (c) In the event that the number of outstanding shares of Common
Stock is increased by a stock dividend payable in Common Stock or by a
subdivision of the outstanding Common Stock, then, from and after the time at
which the adjusted Warrant Price becomes effective pursuant to Subsection (b)
of this Section by reason of such dividend or subdivision, the number of shares
of Common Stock issuable upon the exercise of each Warrant shall be increased
in proportion to such increase in outstanding shares. In the event that the
number of shares of Common Stock outstanding is decreased by a combination of
the outstanding Common Stock, then, from and after the time at which the
adjusted Warrant Price becomes effective pursuant to Subsection (b) of this
Section by reason of such combination, the number of shares of Common Stock
issuable upon the exercise of each Warrant shall be decreased in proportion to
such decrease in the outstanding shares of Common Stock.

            (d) In case of any reorganization or reclassification of the
outstanding Common Stock (other than a change in par value, or

                                       9


from par value to no par value, or as a result of a subdivision or
combination), or in case of any consolidation of the Company with, or merger of
the Company into, another corporation (other than a consolidation or merger in
which the Company is the continuing corporation and which does not result in
any reclassification of the outstanding Common Stock), or in case of any sale
or conveyance to another corporation of the property of the Company as an
entirety or substantially as an entirety, the holder of each Warrant then
outstanding shall thereafter have the right to purchase the kind and amount of
shares of Common Stock and/or other securities and property receivable upon
such reorganization, reclassification, consolidation, merger, sale or
conveyance by a holder of the number of shares of Common Stock which the holder
of such Warrant shall then be entitled to purchase; such adjustments shall
apply with respect to all such changes occurring between the date of this
Warrant Agreement and the date of exercise of such Warrant.

            (e) Subject to the provisions of this Section 9, in case the
Company shall, at any time prior to the exercise of the Warrants, make any
distribution of its assets to holders of its Common Stock as a liquidating or a
partial liquidating dividend, then the holder of Warrants who exercises his
Warrants after the record date for the determination of those holders of Common
Stock entitled to such distribution of assets as a liquidating or partial
liquidating dividend shall be entitled to receive for the Warrant Price per
Warrant, in addition to each share of Common Stock, the amount of such
distribution (or, at the option of the Company, a sum equal to the value of any
such assets at the time of such distribution as determined by the Board of
Directors of the Company in good faith), which would have been payable to such
holder had he been the holder of record of the Common Stock receivable upon
exercise of his Warrant on the record date for the determination of those
entitled to such distribution.

            (f) In case of the dissolution, liquidation or winding-up of the
Company, all rights under the Warrants shall terminate on a date fixed by the
Company, such date to be no earlier than ten (10) days prior to the
effectiveness of such dissolution, liquidation or winding-up and not later than
five (5) days prior to such effectiveness. Notice of such termination of
purchase rights shall be given to the last registered holder of the Warrants,
as the same shall appear on the books of the Company

                                      10


maintained by the Warrant Agent, by registered mail at least thirty (30) days
prior to such termination date.

            (g) In case the Company shall, at any time prior to the expiration
of the Warrants and prior to the exercise thereof, offer to the holders of its
Common Stock any rights to subscribe for additional shares of any class of the
Company, then the Company shall give written notice thereof to the last
registered holder thereof not less than thirty (30) days prior to the date on
which the books of the Company are closed or a record date is fixed for the
determination of the stockholders entitled to such subscription rights. Such
notice shall specify the date as to which the books shall be closed or record
date fixed with respect to such offer of subscription and the right of the
holder thereof to participate in such offer of subscription shall terminate if
the Warrant shall not be exercised on or before the date of such closing of the
books or such record date.

            (h) Any adjustment pursuant to the aforesaid provisions shall be
made on the basis of the number of shares of Common Stock which the holder
thereof would have been entitled to acquire by the exercise of the Warrant
immediately prior to the event giving rise to such adjustment.

            (i) Irrespective of any adjustments in the Warrant Price or the
number or kind of shares purchasable upon exercise of the Warrants, Warrants
previously 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 this Warrant Agreement.

            (j) The Company may retain a firm of independent public accountants
(who may be any such firm regularly employed by the Company) to make any
computation required under this Section, and any certificate setting forth such
computation signed by such firm shall be conclusive evidence of the correctness
of any computation made under this Section.

            (k) If at any time, as a result of an adjustment made pursuant to
paragraph (d) above, the holders of a Warrant or Warrants shall become entitled
to purchase any securities other than shares of Common Stock, thereafter the
number of such securities so purchasable upon exercise of each Warrant and the
Warrant Price for such shares shall be subject to adjustment from

                                      11


time to time in a manner and on terms as nearly equivalent as practicable to
the provisions with respect to the Common Stock contained in paragraphs (b) and
(c).

            (l) No adjustment to the Purchase Price of the Warrants or to the
number of shares of Common Stock purchasable upon the exercise of such Warrants
will be made, however under the following circumstances:

                (i) upon the grant or exercise of any of the options presently
outstanding (or options which may hereafter be granted and/or exercised) under
the Company's 1997 Stock Option Plan for officers, directors and/or employees,
consultants and similar situated parties of the Company; or

                (ii) upon the sale or exercise of the Warrants; or

                (iii) upon exercise of the Representative's Warrant as
otherwise described in the Company's Prospectus dated __________ __, 1997; or

                (iv) upon exercise or sale of the Warrants issuable upon
exercise of the Representative's Warrant; or

                (v) upon any amendment to or change in the term of any rights
or warrants to subscribe for or purchase, or options for the purchase of Common
Stock or convertible securities, including, but not limited to, any extension
of any expiration date of any such right, warrant or option, any change in any
exercise or purchase price provided for in any such right, warrant or option,
any extension of any date through which any convertible securities are
convertible into or exchangeable for Common Stock or any change in the rate at
which any convertible securities are convertible into or exchangeable for
Common Stock.

         Section 10. Fractional Interests. The Warrants may only be exercised
to purchase full shares of Common Stock and the Company shall not be required
to issue fractions of shares of Common Stock on the exercise of Warrants.
However, if a Warrantholder exercises all Warrants then owned of record by him
and such exercise would result in the issuance of a fractional share, the
Company will pay to such Warrantholder, in lieu of the issuance of any
fractional share otherwise issuable, an amount of cash based on the market

                                      12


value of the Common Stock of the Company on the last trading day prior to the
exercise date.

         Section 11. Notices to Warrantholders.

            (a) Upon any adjustment of the Warrant Price and the number of
shares of Common Stock issuable upon exercise of a Warrant, then and in each
such case, the Company shall give written notice thereof to the Warrant Agent,
which notice shall state the Warrant Price resulting from such adjustment and
the increase or decrease, if any, in the number of shares purchasable at such
price upon the exercise of a Warrant, setting forth in reasonable detail the
method of calculation and the facts upon which such calculation is based. The

period of thirty (30) days after such removal or after it has been notified in

successor Warrant Agent, whether appointed by the Company or by such a court,
shall be a bank or trust company, in good standing, incorporated under any

vested with the same powers, rights, duties and responsibility as if it had
been originally named as Warrant Agent without further act or deed and the
former Warrant Agent shall deliver and transfer to the successor Warrant Agent
all cancelled Warrants, records and property at the time held by it hereunder,
and execute and deliver any further assurance or conveyance necessary for the

resignation or removal of the Warrant Agent or the appointment of the successor
Warrant Agent, as the case may be.

         Section 17. Identity of Transfer Agent. Forthwith upon the appointment
of any transfer agent for the shares of Common Stock or of any subsequent
