                                           Company's Common Stock until April
                                           20, 1999, at an exercise price of
                                           $3.17 per share of Common Stock,

                                           Exchange Warrants are redeemable, in
                                           whole but not in part, for $.25 per
                                           Exchange Warrant, at the option of

                                           supplemental agreement, modify the
                                           exercise price from time to time
                                           without obtaining the consent of any
                                           of the holders of the Exchange
                                           Warrants.

Public Warrants . . . . . . . . . . . .    The Public Warrants were issued by
                                           the Company in its initial public
                                           offering (the "IPO") on April 20,
                                           1993. As of February 25, 1998, there
                                           were 1,450,000 Public Warrants
                                           outstanding held by 52 record
                                           holders. Each Public Warrant
                                           entitles the holder to purchase 2.1
                                           shares of the Company's Common Stock
                                           at any time prior to April 20, 1998,
                                           at an exercise price equal to $3.17
                                           per share of Common Stock, subject
                                           to certain adjustments. The exercise
                                           price and the number of shares
                                           purchasable upon exercise of the
                                           Public Warrants are adjusted, among
                                           other reasons, if the Company issues
                                           shares of Common Stock below the
                                           current exercise price of the Public
                                           Warrants.  The Public Warrants are
                                           redeemable, in whole but not in
                                           part, for $.25 per Public Warrant,
                                           at the option of the Company, upon
                                           30 days' written notice and with the
                                           prior written consent of the
                                           representative of the underwriters
                                           of the IPO.

Exchange under the symbol "ISIW."  The following table sets forth, for the
period indicated, the high and low bid quotations for the Public Warrants on
the Nasdaq Small Cap Market.  Trading prices for the Public Warrants on the

for the Nasdaq Small Cap Market.  These over-the-counter market quotations
reflect inter-dealer prices, without retail mark-up, mark- down or commission
and may not represent actual transactions.  The trading market in the Public
Warrants may at times be relatively illiquid due to low volume.

         On February 23, 1998, the last reported sales price for the Public
Warrants as reported on the Nasdaq Small Cap Market was $0.313.


                              PURPOSE OF THE OFFER

         The purpose of the Company's offer to exchange the Public Warrants for
the Exchange Warrants is to provide the holders of the outstanding Public
Warrants with a longer opportunity to profit from the exercise of the warrant.
The Exchange Warrants extend the exercise date to April 20, 1999 from April 20,
1998, as provided in the Public Warrants.  Accordingly, the holders of the
Exchange Warrants will have a longer opportunity to exercise their warrant
rights.

         An additional purpose of the Company's offer to exchange the Public
Warrants for the Exchange Warrants is also to modify the terms providing for
the adjustment of the exercise price and the number of shares purchasable upon
exercise of the warrants.  The Public Warrants provide that the exercise price
and the number of shares





                                       4
<PAGE>   7
purchasable upon exercise is to be adjusted whenever the Company issues Common
Stock at a price less than the current exercise price of the Public Warrants.
The Exchange Warrants contain an identical provision effective only through
April 20, 1998.  Thereafter, no such adjustments will be made.  This
modification may reduce the number of times that the exercise price and the
number of shares purchasable will be adjusted.

         Further, the Exchange Warrants permit the Company and the Transfer
Agent to modify the exercise price from time to time without obtaining the
consent of any of the holders of the Exchange Warrants.

          To the extent that any Public Warrants are exchanged by the Company
at the option of the holders thereof, such Public Warrants will be retired.

         THE BOARD OF DIRECTORS OF THE COMPANY HAS APPROVED THE MAKING OF THE
OFFER BUT IS NOT MAKING ANY RECOMMENDATION TO HOLDERS OF PUBLIC WARRANTS AS TO
WHETHER OR NOT TO TENDER PUBLIC WARRANTS.  EACH HOLDER OF PUBLIC WARRANTS MUST
MAKE HIS OR HER OWN DECISION WHETHER OR NOT TO TENDER PUBLIC WARRANTS, AND, IF
SO, HOW MAY PUBLIC WARRANTS TO TENDER.


                                   THE OFFER

TERMS OF THE OFFER; NUMBER OF PUBLIC WARRANTS

         The Company hereby offers, upon the terms and conditions set forth
herein and in the related Letter of Transmittal, to issue Exchange Warrants for
Public Warrants at the Exchange Ratio. On February 25, 1998, there were
1,450,000 Public Warrants outstanding. The Offer is not conditioned upon any
minimum number of Public Warrants being tendered.

         THE OFFER WILL EXPIRE AT 12:00 MIDNIGHT, NEW YORK CITY TIME, ON THE
EXPIRATION DATE. See "Expiration and Extension of Tender Period; Termination;
Amendment."

         Holders of Public Warrants who wish to exchange Public Warrants for
Exchange Warrants and who validly tender certificates for Public Warrants to
the Company or validly tender Public Warrants by complying with the book-entry
transfer procedures described below and, in each case, who furnish the Letter
of Transmittal and any other required documents to the Transfer Agent, will
have certificates for Exchange Warrants mailed to them by the Transfer Agent,
promptly after tender is accepted by the Company. Subject to the terms and
conditions of the Offer, properly tendered Public Warrants will be accepted on
or promptly after the Expiration Date. Subject to the applicable rules of the
Commission, the Company, however, reserves the right to delay acceptance of
tendered warrants upon the occurrence of any of the conditions set forth below
under the caption "Certain Conditions of the Offer."

         This Offering Circular and the related Letter of Transmittal will be
mailed to record holders of Public Warrants and will be furnished to brokers,
banks and similar persons whose names, or the names of whose nominees, appear
on the list of holders of Public Warrants or, if applicable, who are listed as
participants in a clearing agency's position listing for subsequent transmittal
to beneficial owners of Public Warrants.

EFFECT OF THE OFFER ON THE MARKET FOR THE PUBLIC WARRANTS; STOCK EXCHANGE
LISTING; REGISTRATION UNDER THE EXCHANGE ACT.

         The Public Warrants are currently listed on the Nasdaq Small Cap
market and the Boston Stock Exchange.  The expiration date for the Public
Warrants is April 20, 1998.  Thereafter, no trading market for the Public
Warrants will exist, regardless of whether the Public Warrants are exchanged.





                                       5
<PAGE>   8
LISTING OF THE EXCHANGE WARRANTS

         In general, persons other than affiliates of the Company whose tender
of Public Warrants is accepted will receive unrestricted and freely
transferrable Exchange Warrants.  Although the Company intends to apply for
listing on the Nasdaq Small Cap Market, there can be no assurance that the
Exchange Warrants will be admitted for trading on the Nasdaq Small Cap Market
or that even if initially listed, the Nasdaq Small Cap Market will not delist
the Exchange Warrants in the future if the Exchange Warrants do not meet its
listing requirements.  If the Exchange Warrants not listed for trading on the
Nasdaq Small Cap Market, they would trade on the NASDAQ "bulletin board."  Such
trading would adversely affect the market value and liquidity of the Exchange
Warrants.

EXPIRATION AND EXTENSION OF TENDER PERIOD; TERMINATION; AMENDMENT

         The Offer will expire at 12:00 midnight, New York City time, on the
Expiration Date.  The Company expressly reserves the right, in its sole
discretion, to terminate the Offer and not accept for exchange any Public
Warrants not theretofore accepted for exchange or, subject to applicable law,
to postpone the exchange of Public Warrants upon the occurrence of any of the
conditions specified in this Offering Circular by making a public announcement
of such termination. Applicable federal securities regulations require that the
Company permit Public Warrants tendered pursuant to the Offer to be withdrawn
(i) at any time during the period the Offer remains open and (ii) if not yet
accepted for exchange, after the expiration of 40 business days from
commencement of the Offer. Such regulations require that the Company return the
Public Warrants tendered promptly after termination or withdrawal of a tender
offer.

CERTAIN CONDITIONS OF THE OFFER

         Notwithstanding any other provisions of the Offer, the Company will
not be required to issue Exchange Warrants in respect of any properly tendered
Public Warrants not accepted and may terminate the Offer (by timely public
announcement communicated, unless otherwise required by applicable law or
regulation, by making a release to the Dow Jones News Service) and, subject to
compliance with the applicable rules of the Commission, delay the acceptance of
the tendered warrants if any of the following events shall have occurred (or
shall have been determined by the Company to have occurred) and which in the
Company's sole judgment in any such case makes it inadvisable to proceed with
the Offer:

                 (a)      Any action or proceeding, order, decree or injunction
         shall have been taken or threatened, instituted or pending, or any
         statute, rule, regulation, judgment, order, stay, decree or injunction
         shall have been sought, promulgated, enacted, entered, enforced or
         deemed applicable to the Offer or the Company taken as a whole, by or
         before any court or  governmental, regulatory or administrative
         authority or agency or tribunal, which (i) challenges the making of
         the Offer, the acquisition of the Public Warrants or issuance of the
         Exchange Warrants pursuant to the Offer or might directly or
         indirectly prohibit, prevent, restrict or delay consummation of the
         Offer, or (ii) materially adversely affects the business, operations,
         condition (financial or otherwise), results of operations, prospects,
         assets, liabilities, working capital or reserves of  the Company taken
         as a whole, or otherwise materially impairs in any way the
         contemplated future conduct of the business of the Company taken as a
         whole.

                 (b)      There shall have occurred (i) the declaration of any
         banking moratorium or suspension of payments in respect of banks in
         the United States, (ii) any general suspension of trading in, or
         limitation on prices for, securities on any national securities
         exchange or in the over-the-counter market, (iii) the commencement of
         a war, armed hostilities or any other national or international crisis
         directly or indirectly involving the United States, (iv) any
         limitation (whether or not mandatory) by any government or
         governmental, regulatory or administrative agency or authority on, or
         any event which in the Company's sole judgment might adversely affect,
         the extension of credit by banks or other lending institutions in the
         United States, or (v) in the case of any of the foregoing existing at
         the time of the commencement of the Offer, a material acceleration or
         worsening thereof.





                                       6
<PAGE>   9
                 (c)      There shall have occurred any event that has
         resulted, or may in the sole judgment of the Company result, in an
         actual or threatened change in the business, operations, condition
         (financial or otherwise), results of operations, prospects, assets,
         liabilities, working capital or reserves of the Company.

         The foregoing conditions are for the sole benefit of the Company and
may be asserted by the Company in its sole discretion regardless of the
circumstances (including any action or inaction by the Company) giving rise to
any such conditions, or may be waived by the Company, in its sole discretion,
in whole or in part at any time.

HOW TO TENDER

         A HOLDER OF PUBLIC WARRANTS MAY TENDER PUBLIC WARRANTS BY (a) PROPERLY
COMPETING AND SIGNING THE LETTER OF TRANSMITTAL OR A FACSIMILE THEREOF (ALL
REFERENCES IN THIS OFFERING CIRCULAR TO THE LETTER OF TRANSMITTAL SHALL BE
DEEMED TO INCLUDE A FACSIMILE THEREOF) AND DELIVERING THE SAME, TOGETHER WITH
THE CERTIFICATES REPRESENTING THE PUBLIC WARRANTS BEING TENDERED (OR A
CONFIRMATION OF A BOOK-ENTRY TRANSFER OF SUCH PUBLIC WARRANTS INTO THE TRANSFER
AGENT'S ACCOUNT AT THE DEPOSITARY TRUST COMPANY), TO THE TRANSFER AGENT ON OR
PRIOR TO THE EXPIRATION DATE, OR (b) REQUESTING A BROKER, DEALER, BANK, TRUST
COMPANY OR OTHER NOMINEE TO EFFECT THE TRANSACTION FOR SUCH HOLDER OF PUBLIC
WARRANTS PRIOR TO THE EXPIRATION DATE.

         If tendered warrants are registered in the name of the signer of the
Letter of Transmittal and the Exchange Warrants to be issued in exchange
therefor are to be issued in the name of the registered holder and delivered to
the address appearing on the Company's transfer books, the signature of such
signer need not be guaranteed. If Exchange Warrants are to be issued in the
name of a person other than the registered holder of the Public Warrants, the
tendered certificates must be endorsed or accompanied by stock powers or
written instruments of transfer in form satisfactory to the Company and duly
executed by the registered owner, and the signature on the endorsement or stock
power must be guaranteed by a bank, broker, dealer, credit union, savings
association or other entity that is a member in good standing of a recognized
Medallion Program approved by The Securities Transfer Association, Inc. (any of
the foregoing hereinafter referred to as an "Eligible Institution"). If the
Exchange Warrants are to be delivered to an address other than that of the
registered holder appearing on the Company's transfer books, the signature in
the Letter of Transmittal must be guaranteed by an Eligible Institution.

         The Transfer Agent will establish an account with respect to the
Public Warrants at The Depository Trust Company (the "Book-Entry Facility")
shortly after the date of this Offering Circular, and any financial institution
which is a participant in the Book-Entry Facility may make book-entry delivery
of the warrants by causing the Book-Entry Facility to transfer such warrants
into the Transfer Agent's account in accordance with the Book-Entry Facility's
procedure for such transfer.  Although delivery of warrants may be effected
through book-entry transfer into the Transfer Agent's account at the Book-Entry
Facility, the Letter of Transmittal, with any required signature guarantees and
any other required documents, must in any case be transmitted to and received
by the Transfer Agent on or prior to the Expiration Date at its address set
forth on the last page of this Offering Circular, or the guaranteed delivery
procedure described below must be complied with.  Delivery of documents to the
Book-Entry Facility does not constitute delivery to the Transfer Agent. All
references in this Offering Circular to deposit or delivery of warrants shall
be deemed to include the Book-Entry Facility's book-entry delivery method.

         THE METHOD OF DELIVERY OF PUBLIC WARRANTS AND ALL OTHER DOCUMENTS,
INCLUDING DELIVERY THROUGH THE BOOK-ENTRY FACILITY, IS AT THE ELECTION AND RISK
OF THE WARRANT HOLDER. IF SENT BY MAIL, IT IS RECOMMENDED THAT REGISTERED MAIL,
RETURN RECEIPT REQUESTED, BE USED, AND PROPER INSURANCE BE OBTAINED.

         TO PREVENT BACKUP FEDERAL INCOME TAX WITHHOLDING, A WARRANT HOLDER
MUST PROVIDE THE TRANSFER AGENT WITH HIS OR HER CORRECT TAXPAYER IDENTIFICATION
NUMBER AND CERTIFY WHETHER SUCH WARRANT HOLDER IS SUBJECT TO BACKUP WITHHOLDING
OF FEDERAL INCOME TAX BY COMPLETING THE SUBSTITUTE FORM W-9 INCLUDED IN THE
LETTER OF TRANSMITTAL. CERTAIN WARRANT HOLDERS (INCLUDING, AMONG OTHERS, ALL
CORPORATIONS AND CERTAIN FOREIGN INDIVIDUALS) ARE NOT SUBJECT TO THESE BACKUP
WITHHOLDING AND REPORTING





                                       7
<PAGE>   10
REQUIREMENTS. IN ORDER FOR A FOREIGN INDIVIDUAL TO QUALIFY AS AN EXEMPT
RECIPIENT, THE WARRANT HOLDER  MUST SUBMIT A FORM W-8, SIGNED UNDER PENALTIES
OF PERJURY, ATTESTING TO THAT INDIVIDUAL'S EXEMPT STATUS. SEE "CERTAIN FEDERAL
INCOME TAX CONSEQUENCES--OWNERSHIP AND DISPOSITION OF THE EXCHANGE WARRANTS AND
PUBLIC WARRANTS--BACK-UP WITHHOLDING."

         If a warrant holder desires to tender Public Warrants pursuant to the
Offer and such warrant holder's certificates for such warrants are not
immediately available or time will not permit all of the above documents to
reach the Transfer Agent prior to the Expiration Date, or such warrant holder
cannot complete the procedure for book-entry transfer on a timely basis, such
tender may be effected if the following conditions are satisfied:

                 (a)      such tenders are made by or through an Eligible
         Institution;

                 (b)      a properly completed and duly executed Notice of
         Guaranteed Delivery, in substantially the form provided by the
         Company, is received by the Transfer Agent as provided below on or
         prior to the Expiration Date; and

                 (c)      the certificates for all tendered warrants, in proper
         form for transfer (or confirmation of book-entry transfer of such
         warrants into the Transfer Agent's account at the Book-Entry Facility
         as described above), together with a properly completed and duly
         executed Letter of Transmittal and all other  documents required by
         the Letter of Transmittal are received by the Transfer Agent within
         three New York Stock Exchange, Inc. trading days after the date of
         execution of such Notice of Guaranteed Delivery.

         The Notice of Guaranteed Delivery may be delivered by hand or
transmitted by facsimile transmission or mail to the Transfer Agent and must
include a guarantee by an Eligible Institution in the form set forth in such
Notice of Guaranteed Delivery.

         A tender will be deemed to have been received as of the date when the
tendering warrant holder's duly signed Letter of Transmittal accompanied by
certificates (or a timely confirmation received of a book-entry transfer of
such warrants into the Transfer Agent's account at the Book-Entry Facility) or
a Notice of Guaranteed Delivery from an Eligible Institution is received by the
Transfer Agent. Issuances of Exchange Warrants in exchange for Public Warrants
tendered pursuant to a Notice of Guaranteed Delivery by an Eligible Institution
will be made only against deposit of the Letter of Transmittal (and any other
required documents) and the tendered certificates (or a timely confirmation
received of a book-entry transfer of such warrants into the Transfer Agent's
account at the Book-Entry Facility) with the Transfer Agent.

         Any whole number of Public Warrants may be tendered. Tendering warrant
holders may tender less than all of the Public Warrants represented by the
certificates they hold provided they appropriately indicate this fact on the
Letter of Transmittal accompanying the tendered Public Warrant certificates.
Tenders of fractional warrants will not be accepted.

         With respect to tenders of Public Warrants, the Company reserves full
discretion to determine whether the documentation is complete and generally to
determine all questions as to tenders, including the date of receipt of a
tender, the propriety of execution of any document, and other questions as to
the validity, form, eligibility or acceptability of any tender. The Company
reserves the right to reject any tender not in proper form or otherwise not
valid or the acceptance for exchange of which may, in the opinion of the
Company's counsel, be unlawful or to waive any irregularities or conditions,
and the Company's interpretation of the terms and conditions of the Offer
(including the instructions on the Letter of Transmittal) will be final. The
Company shall not be obligated to give notice of any defects or irregularities
in tenders and shall not incur any liability for failure to give any such
notice. Public Warrants shall not be deemed to have been duly or validly
tendered unless and until all defects and irregularities have been cured or
waived. Certificates for all improperly tendered warrants, as well as balance
certificates representing warrants in excess of those tendered for exchange,
will be returned (unless irregularities and





                                       8
<PAGE>   11
defects are timely cured or waived), without cost to the tendering warrant
holder (or, in the case of warrants delivered by book-entry transfer within the
Book-Entry Facility, will be credited to the account maintained within the
Book-Entry Facility by the participant who delivered such warrants), promptly
after the Expiration Date.

TERMS AND CONDITIONS OF THE LETTER OF TRANSMITTAL

         The Letter of Transmittal contains, among other things, certain terms
and conditions, which are summarized below and are part of the Offer.

         Public Warrants tendered in exchange for Exchange Warrants (or a
timely confirmation of a book-entry transfer of such warrants into the Transfer
Agent's account at the Book-Entry Facility) must be received by the Transfer
Agent, with the Letter of Transmittal and any other required documents by 12:00
midnight, New York City time, on or prior to the Expiration Date, or within the
time periods set forth above in "How to Tender" pursuant to a Notice of
Guaranteed Delivery from an Eligible Institution. The party tendering the
warrants for exchange (the "Holder") sells, assigns and transfers the Public
Warrants to the Transfer Agent and irrevocably constitutes and appoints the
Transfer Agent as the Holder's agent and attorney-in-fact to cause the warrants
to be transferred and exchanged. The Holder warrants that it has full power and
authority to tender, exchange, sell, assign and transfer the Public Warrants
and to acquire the Exchange Warrants issuable upon the exchange of such
tendered warrants, that the Company will acquire good and unencumbered title to
the tendered warrants, free and clear of all liens, restrictions, charges and
encumbrances, and that the Public Warrants tendered for exchange are not
subject to any adverse claims when accepted by the Company. The Holder also
warrants that it will, upon request, execute and deliver any additional
documents deemed by the Company to be necessary or desirable to complete the
exchange, sale, assignment and transfer of the tendered warrants.  All
authority conferred or agreed to be conferred in the Letter of Transmittal by
the Holder will survive the death or incapacity of the Holder and any
obligation of the Holder shall be binding upon the heirs, personal
representatives, successors and assigns of such Holder.

         Signature(s) on the Letter of Transmittal will be required to be
guaranteed and endorsement(s) on the certificates being tendered will be
required as set forth above in "How to Tender."  All questions as to the
validity, form, eligibility (including time of receipt) and acceptability of
any tender will be determined by the Company, in its sole discretion, and such
determination will be final and binding. Unless waived by the Company,
irregularities and defects must be cured by the Expiration Date. The Company
will pay all stock transfer taxes applicable to the transfer and exchange of
Public Warrants tendered unless warrants are transferred to a third party.

WITHDRAWAL RIGHTS

         All tenders may be withdrawn (i) at any time prior to the Expiration
Date or (ii) if not yet accepted for exchange, after April 23, 1998.   To be
effective, a notice of withdrawal must be timely received by the Transfer Agent
at the address set forth below under "Transfer Agent" and on the back cover of
this Offering Circular. Any notice of withdrawal must specify the person named
in the Letter of Transmittal as having tendered the number of Public Warrants
to be withdrawn and the name of the registered holder of such warrants.  If the
Public Warrants have been physically delivered to the Transfer Agent, the
tendering warrant holder must also submit the serial number shown on the
particular certificate(s) to be withdrawn. If the Public Warrants have been
delivered pursuant to the book-entry procedures set forth above under "How to
Tender," any notice of withdrawal must specify the name and number of the
participant's account at the Book-Entry Facility to be credited with the
withdrawn warrants. The Transfer Agent will return the properly withdrawn
Public Warrants as soon as practicable following receipt of notice of
withdrawal. All questions as to the validity, including time of receipt, of
notices of withdrawals will be determined by the Company, and such
determination will be final and binding on all parties.

ACCEPTANCE OF TENDERS

         Subject to the terms and conditions of the Offer, Public Warrants
tendered (either physically or through book-entry delivery as described in "How
to Tender") with a properly executed Letter of Transmittal and all other





                                       9
<PAGE>   12
required documentation, and not withdrawn, will be accepted on or promptly
after the Expiration Date. Subject to such terms and conditions, delivery of
certificates of Exchange Warrants to be issued in exchange for properly
tendered Public Warrants will be made by the Transfer Agent promptly after
acceptance of the tendered warrants. Subject to the applicable rules of the
Commission, the Company, however, reserves the right to delay acceptance of
tendered warrants upon the occurrence of any of the conditions set forth above
under the caption "Certain Conditions of the Offer."

         The tender of warrants pursuant to any one of the procedures set forth
in "How to Tender" will constitute an agreement between the tendering warrant
holder and the Company upon the terms and subject to the conditions of the
Offer.

SOLICITATION OF TENDERS; EXPENSES

         The Company will not make any payments to brokers, dealers or other
persons for soliciting or recommending acceptances of the Offer.  The Company
will, however, pay brokerage houses and other custodians, nominees and
fiduciaries the reasonable out-of-pocket expenses incurred by them in
forwarding copies of this Offering Circular and related documents to the
beneficial owners of the Public Warrants and in handling or forwarding tenders
for their customers.

         No person has been authorized to give any information or to make any
representations in connection with the Offer other than those contained in this
Offering Circular. If given or made, such information or representations should
not be relied upon as having been authorized by the Company. Neither the
delivery of this Offering Circular nor any exchange made hereunder shall, under
any circumstances, create any implication that there has been no change in the
affairs of the Company since the respective dates as of which information is
given herein. This Offering Circular does not constitute an offer to exchange,
or a solicitation of an offer to exchange, any securities other than the
securities covered by the Offering Circular by the Company or any other person,
nor does it constitute an offer to exchange or a solicitation of an offer to
exchange such securities by the Company, or any such other person in any
jurisdiction in which or to any person to whom it is unlawful to make any such
offer or solicitation. In any jurisdiction the laws of which require the offer
to be made by a licensed broker or dealer, the offer is being made on behalf of
the Company by one or more registered brokers or dealers licensed under the
laws of such jurisdiction.


                    CERTAIN FEDERAL INCOME TAX CONSEQUENCES

         In the opinion of the Company, the following discussion accurately
sets forth the material federal income tax consequences of (i) the exchange of
Public Warrants for Exchange Warrants pursuant to the Offer, and (ii) the
ownership and disposition of Exchange Warrants.  The Company has concluded that
the exchange of Public Warrants for Exchange Warrants pursuant to the Offer
qualifies as a tax-free reorganization within the meaning of Section
368(a)(1)(E) of the Internal Revenue Code of 1986, as amended (the "Code").
The opinion of the Company is not binding on the Internal Revenue Service (the
"Service") or the courts.  There can be no assurances that the Service will
take a similar view as to any of the tax consequences described below. The
Company has not sought, nor does it intend to seek, a ruling from the Service
that its position as reflected in the following discussion will be accepted by
the Service.

         The following discussion is a summary of certain federal income tax
consequences relevant to (i) the exchange of Public Warrants for Exchange
Warrants pursuant to the Offer, and (ii) the ownership and disposition of
Exchange Warrants, but does not purport to be a complete analysis of all the
potential tax effects thereof. The discussion is based upon the Code,
Regulations, and Service rulings and judicial decisions now in effect, all of
which are subject to change at any time by legislative, judicial or
administrative action. No information is provided herein with respect to estate
and gift, state, local or foreign tax consequences. This information is
directed to offerees who will hold the Exchange Warrants as "capital assets"
within the meaning of Section 1221 of the Code. In addition, this discussion
does not address the tax consequences to certain holders as to whom special
rules apply (including





                                       10
<PAGE>   13
life insurance companies, tax-exempt organizations, banks and dealers in
securities, individuals who are not citizens or residents of the Untied States,
and foreign corporations). Each offeree should consult his or her own tax
advisor concerning the tax consequences to him of the exchange of Public
Warrants for Exchange Warrants pursuant to the Offer, and of the ownership and
disposition of Exchange Warrants.

EXCHANGE OF PUBLIC WARRANTS FOR EXCHANGE WARRANTS

         Tax Consequences of the Exchange to the Tendering Warrant Holder. The
exchange of Public Warrants for Exchange Warrants pursuant to the Offer will
qualify as a recapitalization, and therefore, a reorganization within the
meaning of Section 368(a)(1)(E) of the Code. Consequently, a tendering warrant
holder will not recognize gain or loss on the exchange of Public Warrants for
Exchange Warrants.

         Tax Consequences of the Exchange to the Company. No gain or loss will
be recognized to the Company upon its receipt of Public Warrants in exchange
for Exchange Warrants pursuant to the Offer.

         Treatment of Exchange Warrants. A warrant holder's initial tax basis
for the Exchange Warrants received pursuant to the Offer will be equal to the
basis of the Public Warrants surrendered in exchange therefor.  The holding
period of the Exchange Warrants will include the holding period during which
the Public Warrants surrendered in exchange therefor were held by the warrant
holder, provided that the Public Warrants were held as capital assets on the
date of the exchange.

OWNERSHIP AND DISPOSITION OF THE EXCHANGE WARRANTS

         Disposition of Exchange Warrants. Generally, any sale or other
disposition of the Exchange Warrants will be a taxable event and will result in
capital gain or loss if the Exchange Warrants are held as a capital asset at
the time of the sale or other disposition. The amount of such gain or loss will
generally be the difference between the adjusted basis of the Exchange Warrants
on the date of the sale or other disposition and the cash and fair market value
of the property received. Such gain or loss will be long-term gain or loss if
the Exchange Warrants are held for more than eighteen months.

         Exercise of Exchange Warrants. In general, no gain or loss will be
recognized for federal income tax purposes on exercise of the Exchange
Warrants.  In general, the tax basis for shares of Common Stock received on
conversion will be equal to the tax basis of the Exchange Warrants surrendered
therefor, increased by the amount paid to exercise such warrants.  The holding
period of the shares of Common Stock begins upon acquisition of the Common
Stock.

         Backup Withholding. Under the backup withholding provisions of the
Code and applicable Regulations, a holder of Exchange Warrants may be subject
to back-up withholding at a rate of thirty-one percent (31%) with respect to
dividends or interest paid, original issue discount accrued with respect to, or
proceeds received from a sale, exchange or redemption of, Exchange Warrants.
The payor will be required to deduct and withhold a tax if (i) the payee fails
to furnish a taxpayer identification number ("TIN") to the payor or establish
an exemption from backup withholding, (ii) the Service notifies the payor that
the TIN furnished by the payee is incorrect, (iii) there has been a notified
payee under reporting with respect to interest, dividends or original issue
discount described in Section 3406(c) of the Code, or (iv) there has been a
failure of the payee to certify under the penalty of perjury that the payee is
not subject to withholding under Section 3406(a)(1)(C) of the Code. Backup
withholding will not be required if such holder (a) is a corporation or comes
within certain other exempt categories and when required demonstrates this fact
or (b) provides a taxpayer identification number, certifies as to no loss of
exemption from backup withholding, and otherwise complies with applicable
requirements of the backup withholding rules.

               DESCRIPTION OF EXCHANGE WARRANTS, PUBLIC WARRANTS
                                AND COMMON STOCK

THE PUBLIC WARRANTS

         The Public Warrants were issued by the Company in the IPO on April 20,
1993. The following is a brief summary of certain provisions of the Public
Warrants, but such summary does not purport to be complete and is qualified in
all respects by reference to the actual text of the Warrant Agreement (the
"Public Warrant Agreement"), dated as of April 20, 1993, by and among the
Company, the Transfer Agent and Thomas James Associates, Inc., as
representative of the underwriters in the IPO (the "Representative").  A copy
of the Public Warrant Agreement has been filed as Exhibit 99.9 to the Schedule
13E-4. See "Available Information."

         Exercise Price and Terms.  As of February 23, 1998, there were
1,450,000 Public Warrants outstanding held by 52 record holders.  Each Public
Warrant entitles the holder to purchase 2.1 shares of the Company's Common
Stock at any time prior to April 20, 1998, at an exercise price equal to $3.17
per share of Common Stock, subject to adjustment in accordance with the
anti-dilution and other provisions referred to below.  The holder of any Public
Warrant may exercise such Public Warrant by surrendering the certificate
representing the Public Warrant to the Transfer Agent, with the subscription
form on the reverse side of such certificate properly completed and executed,
together with payment of the exercise price.  The Public Warrants may be
exercised at any time in whole or in part at the applicable exercise price
until expiration of the Public Warrants on April 20, 1998.

         The Public Warrants are subject to redemption, in whole but not in
part, at $.25 per Public Warrant on 30 days' written notice with the
Representative's prior written consent.  The Company shall promptly announce
any redemption by publication in The Wall Street Journal at the time of the
mailing of the redemption notice to the holders.  In the event the Company
exercises the right to redeem the Public Warrants, such Public Warrants will be
exercisable until the close of business on the date for redemption fixed in
such notice.  If any Public Warrant called for redemption is not exercised by
such time, it will cease to be exercisable and the holder will be entitled only
to the redemption price.

         The exercise price of the Public Warrant bears no relation to any
objective criteria of value and should in no event be regarded as an indication
of any future market price of the Common Stock.

         Adjustments.   The exercise price and the number of shares of Common
Stock purchasable upon the exercise of the Public Warrants are subject to
adjustment upon the occurrence of certain events, including stock dividends,
stock splits, combinations or reclassifications of the Common Stock, or sale by
the Company of shares of its Common Stock at a price below the then applicable
exercise price of the Public Warrants.  Additionally, an adjustment would be
made in the case of a reclassification or exchange of Common Stock,
consolidation or merger of the Company with or into another corporation or sale
of all or substantially all of the assets of the Company in order to enable
holders of Public Warrants to acquire the kind and number of shares of stock or
other securities or property receivable in such event by a holder of the number
of shares of Common Stock that might otherwise have been purchased upon the
exercise of the Public Warrants.  No adjustments will be made until the number
of shares issued by the Company exceeds 5% of the number of Common Stock and
certain convertible securities of the Company outstanding following the
consummation of the IPO, and thereafter no adjustments will be made until the
cumulative adjustments in the exercise price per share amount to $.05 or more.
No adjustment to the exercise price of the shares subject to the Public
Warrants will be made for dividends (other than stock dividends), if any, paid
on the Common Stock or for securities issued pursuant to the Company's Stock
Option Plan or other employee benefit plans of the Company.

         Transfer, Exchange and Exercise.  The Public Warrants are in
registered form and may be presented to the Transfer Agent for transfer,
exchange or exercise at any time on or prior to their expiration date, April
20, 1998, at which time the Public Warrants become wholly void and of no value.
A holder of Public Warrants may also sell





                                       12
<PAGE>   15
the Public Warrants instead of exercising them.  There can be no assurance,
however, that the market for the Public Warrants will continue.

         Each such holder of Public Warrants will be entitled to exchange his
or her Public Warrants for Exchange Warrants, in accordance with and subject to
the terms of the Offer.

         To the Company's knowledge, there have been no transactions involving
the Public Warrants effected during the past 40 business days by the Company,
any executive officer or director of the Company or any other person in
control, directly or indirectly, of the Company.  None of the officers,
directors or affiliates of the Company holds any of the Public Warrants.

THE EXCHANGE WARRANTS

         The following is a brief summary of certain provisions of the Exchange
Warrants, but such summary does not purport to be complete and is qualified in
all respects by reference to the actual text of the Warrant Agreement (the
"Exchange Warrant Agreement"), dated as of February 25, 1998, between the
Company and the Transfer Agent.  A copy of the Exchange Warrant Agreement has
been filed as Exhibit 99.10 to the Schedule 13E-4. See "Available Information."

         Exercise Price and Terms.  Each Exchange Warrant entitles the holder
to purchase 2.1 shares of the Company's Common Stock at any time prior to April
20, 1998, at an exercise price equal to $3.17 per share of Common Stock,
subject to adjustment in accordance with the anti-dilution and other provisions
referred to below.  The holder of any Exchange Warrant may exercise such
Exchange Warrant by surrendering the certificate representing the Exchange
Warrant to the Transfer Agent, with the subscription form on the reverse side
of such certificate properly completed and executed, together with payment of
the exercise price.  The Exchange Warrants may be exercised at any time in
whole or in part at the applicable exercise price until expiration of the
Exchange Warrants on April 20, 1999.

         The Exchange Warrants are subject to redemption, in whole but not in
part, at $.25 per Exchange Warrant on 30 days' written notice.  The Company
shall promptly announce any redemption by publication in The Wall Street
Journal at the time of the mailing of the redemption notice to the holders.  In
the event the Company exercises the right to redeem the Exchange Warrants, such
Exchange Warrants will be exercisable until the close of business on the date
for redemption fixed in such notice.  If any Exchange Warrant called for
redemption is not exercised by such time, it will cease to be exercisable and
the holder will be entitled only to the redemption price.

         The exercise price of the Exchange Warrant bears no relation to any
objective criteria of value and should in no event be regarded as an indication
of any future market price of the Common Stock.

         Adjustments.   The exercise price and the number of shares of Common
Stock purchasable upon the exercise of the Exchange Warrants are subject to
adjustment upon the occurrence of certain events, including stock dividends,
stock splits, combinations or reclassifications of the Common Stock.  Until
April 20, 1998, adjustments will also be made if the Company sells shares of
its Common Stock at a price below the exercise price of the Exchange Warrants.
Thereafter, no further adjustments will be made as a result of stock sales (if
any) at less than the exercise price of the Exchange Warrants.  An adjustment
would be made in the case of a reclassification or exchange of Common Stock,
consolidation or merger of the Company with or into another corporation or sale
of all or substantially all of the assets of the Company in order to enable
holders of Exchange Warrants to acquire the kind and number of shares of stock
or other securities or property receivable in such event by a holder of the
number of shares of Common Stock that might otherwise have been purchased upon
the exercise of the Exchange Warrants.  No adjustments will be made until the
number of shares issued by the Company exceeds 5% of the number of shares
outstanding as of the date of the Exchange Warrant Agreement, and thereafter no
adjustments will be made until the cumulative adjustments in the exercise price
per share amount to $.05 or more.  No adjustment to the exercise price of the
shares subject to the Exchange Warrants will be made for dividends (other than
stock dividends), if any, paid





                                       13
<PAGE>   16
on the Common Stock or for securities issued pursuant to the Company's Stock
Option Plan or other employee benefit plans of the Company.

         Modification of the Exercise Price.  The Transfer Agent and the
Company may, by amendment or supplemental agreement, modify the exercise price
from time to time without obtaining the consent of any of the holders of the
Exchange Warrants.

         Transfer, Exchange and Exercise.  The Exchange Warrants are in
registered form and may be presented to the Transfer Agent for transfer,
exchange or exercise at any time on or prior to their expiration date, April
20, 1998, at which time the Exchange Warrants become wholly void and of no
value.  If a market for the Exchange Warrants develops, the holder of Exchange
Warrants may also sell the Exchange Warrants instead of exercising them.  There
can be no assurance, however, that the market for the Exchange Warrants will
develop or continue.

COMMON STOCK

         Holders of Common Stock are entitled to one vote for each share held
on all matters submitted to a vote of stockholders. There is no cumulative
voting with respect to the election of Directors, with the result that the
holders of more than 50% of the shares voted in the election of Directors can
elect all of the Directors. Holders of Common Stock are entitled to receive
ratably such dividends, if any, as may be declared by the Board of Directors of
the Company out of funds legally available therefor. Upon the liquidation,
dissolution or winding up of the Company, the holders of Common Stock are
entitled to receive ratably the net assets of the Company after payment of all
debts and liabilities and liquidation preferences of outstanding shares of
Preferred Stock. Holders of Common Stock have no preemptive, subscription,
redemption or conversion rights.

         Facsimile copies of the Letter of Transmittal will be accepted.  The
Letter of Transmittal, warrant certificates and other required documents should
be sent or delivered by each warrant holder or his or her broker, dealer,
commercial bank, trust company or other nominees to the Transfer Agent at the

Ladies and Gentlemen:

   Pursuant to the terms and subject to the conditions of the Offer (as
described below) of Integrated Security Systems, Inc., a Delaware corporation
(the "Company"), to holders of the Company's Redeemable Common Stock Purchase
Warrants (the "Public Warrants"), as set forth in the Offering Circular dated
February 26, 1998 (the "Offering Circular") and this Letter of Transmittal
(which, together with the Offering Circular, constitute the "Offer"), receipt
of which are hereby acknowledged, the signer of this Letter of Transmittal (the
"Holder") hereby accepts the Offer and tenders the Public Warrants listed on
this Letter of Transmittal in exchange for one warrant (the "Exchange Warrant")
to purchase 2.1 shares of the Company's common stock, par value $.01 per share
(the "Common Stock"), until April 20, 1999, at an exercise price of $3.17 per
share of Common Stock, for each Public Warrant tendered and accepted. No
fractional Exchange Warrants will be issued.

   Accordingly, subject to, and effective upon, acceptance for exchange of the
Public Warrants tendered herewith in accordance with the terms and conditions
of the Offer, the Holder hereby sells, assigns and transfers to the Company all
right, title and interest in and to all of the Public Warrants that are being
tendered for exchange hereby and hereby irrevocably constitutes and appoints
the Transfer Agent the true and lawful agent and attorney-in-fact of the Holder
with respect to such warrants, with full power of substitution (such power of
attorney being deemed to be an irrevocable power coupled with an interest), to
(i) deliver certificates for Public Warrants tendered hereby or transfer
ownership of such warrants on the account books maintained by the Book-Entry
Facility together, in either such case, with the accompanying evidences of
transfer and authority, to the Company upon the receipt by the Transfer Agent,
as the Holder's agent, of the consideration therefor pursuant to the Offer,
(ii) present such warrants for registration and transfer on the books of the
Company and (iii) receive all benefits and otherwise exercise all rights of
beneficial ownership of such warrants.

   THE HOLDER HEREBY REPRESENTS AND WARRANTS THAT THE HOLDER HAS FULL POWER AND
AUTHORITY TO TENDER, EXCHANGE, SELL, ASSIGN AND TRANSFER THE PUBLIC WARRANTS
TENDERED HEREBY AND TO ACQUIRE THE EXCHANGE WARRANTS ISSUABLE UPON THE EXCHANGE
OF SUCH TENDERED WARRANTS, THAT THE COMPANY WILL ACQUIRE GOOD AND UNENCUMBERED
TITLE TO SUCH TENDERED WARRANTS, FREE AND CLEAR OF ALL LIENS, RESTRICTIONS,
CHARGES AND ENCUMBRANCES, AND THAT THE PUBLIC WARRANTS TENDERED HEREBY ARE NOT
SUBJECT TO ANY ADVERSE CLAIM WHEN THE SAME ARE ACCEPTED BY THE COMPANY.  THE
HOLDER WILL, UPON REQUEST, EXECUTE AND DELIVER ANY ADDITIONAL DOCUMENTS DEEMED
BY THE COMPANY OR THE TRANSFER AGENT TO BE NECESSARY OR DESIRABLE TO COMPLETE
THE EXCHANGE, SALE, ASSIGNMENT AND TRANSFER OF THE PUBLIC WARRANTS TENDERED
HEREBY.

   All authority herein conferred or agreed to be conferred in this Letter of
Transmittal shall survive the death or incapacity of the Holder and any
obligation of the Holder hereunder shall be binding upon the heirs, personal
representatives, successors and assigns of the Holder.  Except as stated in the
Offering Circular, this tender is irrevocable.

   A tender of warrants pursuant to the procedures described in the Offering
Circular and in the instructions hereto will constitute the Holder's acceptance
of the terms and conditions of the Offer and a binding agreement between the
tendering warrant holder and the Company upon the terms and subject to the
conditions of the Offer.  The Holder recognizes that, under certain
circumstances set forth in the Offering Circular, the Company may not be
required to accept any of the Public Warrants tendered for exchange hereby.
Unless otherwise indicated in the box entitled "Special Issuance Instructions,"
the Holder hereby directs that the certificates for the Exchange Warrants
and/or any certificates for any Public Warrants not exchanged be issued in the
name of the Holder.  The Holder understands that holders who tender Public
Warrants by book-entry transfer ("Book-Entry Warrant Holders") may request that
any Public Warrants not exchanged will be returned by crediting the account
maintained by the Book-Entry Facility, by making an appropriate entry under
"Special Issuance Instructions."  Unless otherwise indicated in the box

                                  INSTRUCTIONS

             FORMING PART OF THE TERMS AND CONDITIONS OF THE OFFER.

      1.       GUARANTEE OF SIGNATURES.  Except as otherwise provided below,
signatures on this Letter of Transmittal must be guaranteed by a bank, broker,
dealer, credit union, savings association or other entity that is a member in
good standing of a recognized Medallion Program approved by The Securities
Transfer Association, Inc. (an "Eligible Institution"), unless the Public
Warrants tendered hereby are tendered (i) by the registered holder (which term,
for purposes of this document, shall include any participant in the Book-Entry
Facility whose name appears on a security position listing as the owner of the
Public Warrants) of such Public Warrants who has completed neither the box
labeled "Special Issuance Instructions" nor the box labeled "Special Delivery
Instructions" herein or (ii) for the account of an Eligible Institution.  See
Instruction 5.  If the certificates representing the tendered Public Warrants
are registered in the name of a person other than the signer of this Letter of
Transmittal, or if payment is to be made or delivered to, or certificates
evidencing the unexchanged Public Warrants are to be issued or returned to, a
person other than the registered owner, then the certificates representing the
tendered Public Warrants must be endorsed or accompanied by duly executed stock
powers, in either case signed exactly as the name or names of the registered
owner or owners appear on such certificates or stock powers guaranteed by an
Eligible Institution as provided herein.  See Instruction 5.

      2.       DELIVERY OF LETTER OF TRANSMITTAL AND CERTIFICATES.  In order to
participate in the Offer and receive Exchange Warrants, a warrant holder must
properly complete and duly execute (with signatures guaranteed if required by
Instructions 1 or 5) the Letter of Transmittal (or a facsimile thereof) and
mail or deliver it, together with the certificate(s) representing the Public
Warrants to be tendered for exchange (or the Transfer Agent must receive a
timely confirmation of a book-entry transfer into the Transfer Agent's account
at the Book-Entry Facility) and any other required documents, to the Transfer
Agent.  The Transfer Agent must receive the foregoing documents and instruments
on or prior to the Expiration Date.  Delivery of documents to the Book-Entry
Facility does not constitute delivery to the Transfer Agent.

      If a warrant holder desires to tender Public Warrants pursuant to the
Offer and such warrant holder's certificate(s) for such warrants are not
immediately available, or if the procedure for book-entry transfer cannot be
completed on a timely basis, or such warrant holder cannot deliver the
certificate(s) and all other required documents to the Transfer Agent prior to
the Expiration Date, such warrants may be tendered if all of the following
guaranteed delivery procedures are complied with: (i) such tenders are made by
or through an Eligible Institution; (ii) a properly completed and duly executed
Notice of Guaranteed Delivery, in substantially the form provided by the
Company, is received by the Transfer Agent on or prior to the Expiration Date,
and (iii) the certificates for all tendered warrants, in proper form for
transfer (or confirmation of book-entry transfer of such warrants into the
Transfer Agent's account at the Book-Entry Facility as described in the
Offering Circular), together with a properly completed and duly executed Letter
of Transmittal and all other documents required by this Letter of Transmittal,
are received by the Transfer Agent within three New York Stock Exchange, Inc.
trading days after the date of execution of such Notice of Guaranteed Delivery,
all as provided under the caption "The Offer--How to Tender" in the Offering
Circular.

      All questions as to the validity, form, eligibility (including time of
receipt) and acceptability of Public Warrants tendered will be determined by
the Company, in its sole discretion, and such determinations will be final and
binding. The Company reserves the right to reject any and all tenders
determined by it not to be in proper form or otherwise not valid or the
acceptance for exchange of which may, in the opinion of the Company's counsel,
be unlawful.  The Company's interpretation of the terms and conditions of the
Offer (including the Letter of Transmittal and Instructions thereto) will also
be final and binding.  The Company and the Transfer Agent are not under any
duty to give notification of any irregularities or defects and shall not incur
any liability for failure to give any such notification.  Tenders will not be
deemed to have been made until such irregularities or defects have been cured
or waived.  Any tender (including the Letter of Transmittal and warrant
certificates) that is not properly completed and executed, and as to which
irregularities or defects are not cured or waived, will be returned by the





                                      6
<PAGE>   7
Transfer Agent to the tendering warrant holder promptly after the Expiration
Date (or, in the case of warrants delivered by book-entry transfer within the
Book-Entry Facility, the tendered warrants will be credited to the account
maintained within the Book-Entry Facility by the participant and the Book-Entry
Facility which delivered such warrants).

      THE METHOD OF DELIVERY OF THIS LETTER OF TRANSMITTAL, THE CERTIFICATES
FOR PUBLIC WARRANTS AND ALL OTHER REQUIRED DOCUMENTS, INCLUDING DELIVERY
THROUGH THE BOOK-ENTRY FACILITY, IS AT THE ELECTION AND RISK OF THE TENDERING
WARRANT HOLDER AND, EXCEPT AS OTHERWISE PROVIDED IN THIS INSTRUCTION 2, THE
DELIVERY WILL BE DEEMED MADE ONLY WHEN ACTUALLY RECEIVED BY THE TRANSFER AGENT.
IF DELIVERY IS BY MAIL, REGISTERED MAIL, WITH RETURN RECEIPT REQUESTED,
PROPERLY INSURED, IS RECOMMENDED.

      No alternative, conditional or contingent tenders will be accepted.  All
tendering warrant holders, by execution of this Letter of Transmittal or
facsimile thereof, waive any rights to receive any notice of the acceptance of
their tender.

      3.       INADEQUATE SPACE.  If the space provided herein is inadequate,
the certificate numbers and the number of warrants should be listed on a
separate signed schedule attached hereto.

      4.       PARTIAL TENDERS (NOT APPLICABLE TO BOOK-ENTRY WARRANT HOLDERS).
If fewer than all the warrants evidenced by any certificate submitted are to be
tendered, the number of warrants that are to be tendered should be stated in
the box entitled "Number of Warrants Tendered."  New certificate(s) for the
remainder of the warrants which are evidenced by old certificate(s) will be
sent to the registered holder of the certificate(s) tendered, unless otherwise
provided by checking the appropriate box on the Letter of Transmittal, as soon
as practicable after the tender has been accepted.  All warrants represented by
certificates listed are deemed to have been tendered unless otherwise
indicated.

      5.       SIGNATURES ON LETTER OF TRANSMITTAL, STOCK POWERS AND
ENDORSEMENTS.  If this Letter of Transmittal is signed by the registered holder
of the certificate(s) tendered hereby, the signature must correspond exactly
with the name as written on the face of the certificate(s) without alteration,
enlargement or any change whatsoever.

      If the Public Warrants tendered hereby are owned of record by two or more
joint owners, all such owners must sign this Letter of Transmittal.

      If any tendered Public Warrants are registered in different names on
several certificates, it will be necessary to complete, sign and submit as many
separate Letters of Transmittal as there are different registrations of
certificates.

      When this Letter of Transmittal is signed by the registered holder(s) of
the certificate(s) listed and transmitted hereby, no endorsement of
certificates or separate stock powers are required.  If, however, any
certificates for Exchange Warrants or any certificates for Public Warrants not
tendered are to be issued to a person other than the registered holder, then
endorsement of certificates transmitted hereby or separate stock powers are
required.  Signatures on any such certificate(s) or stock powers must be
guaranteed by an Eligible Institution. If this Letter of Transmittal is signed
by a person other than the registered holder of the certificate(s) listed, such
certificate(s) must be endorsed or accompanied by appropriate stock powers, in
either case signed exactly as the name or names of the registered holder or
holders appear on the certificate(s).  Signatures on such certificate(s) or
stock powers must be guaranteed by an Eligible Institution.

      If this Letter of Transmittal or any certificate(s) or stock powers are
signed by trustees, executors, administrators, guardians, attorneys-in-fact,
officers of corporations or others acting in a fiduciary or representative
capacity, such persons should so indicate when signing, and proper evidence
satisfactory to the Company of their





                                      7
<PAGE>   8
authority so to act must be submitted.  Signatures on any such certificate(s)
or stock powers must be guaranteed by an Eligible Institution.

      6.       DELIVERY OF EXCHANGE WARRANTS.  Delivery of Exchange Warrants
will be made promptly after the Expiration Date for all Public Warrants
properly tendered and accepted for exchange by the Company.  The Exchange
Warrants will be issued in the name of the registered holder(s) of the Public
Warrants and mailed to him or her, unless otherwise provided in the appropriate
box on this Letter of Transmittal.  In the case of tenders by Notice of
Guaranteed Delivery, Exchange Warrants will not be delivered until the Letter
of Transmittal, the certificate(s) representing tendered warrants relating to
such Notice of Guaranteed Delivery (or a timely confirmation of a book-entry
transfer of such warrants into the Transfer Agent's account at the Book-Entry
Facility) and all other required documents have been received by the Transfer
Agent.

      7.       STOCK TRANSFER TAXES.  The Company will pay all stock transfer
taxes, if any, applicable to the exchange of warrants tendered and accepted
pursuant to the Offer.  If, however, issuance of Exchange Warrants is to be
made to, or (in circumstances permitted hereby) if warrants not tendered are to
be registered in the name of any person other than the registered holder, or if
tendered certificates are registered in the name of any person other than the
person(s) signing this Letter of Transmittal, the amount of any stock transfer
taxes (whether imposed on the registered holder or such person) payable on
account of the transfer must be paid to the Company or the Transfer Agent (or
the transferee must establish to the satisfaction of the Company the such taxes
have been paid or need not be paid) before the Exchange Warrants will be
issued.

      EXCEPT AS PROVIDED IN THIS INSTRUCTION 7, IT WILL NOT BE NECESSARY FOR
TRANSFER TAX STAMPS TO BE AFFIXED TO THE CERTIFICATES LISTED IN THIS LETTER OF
TRANSMITTAL.

      8.       WAIVER OF CONDITIONS.  Subject to limitations set forth in the
Offering Circular, the conditions of the Offer may be waived by the Company, in
whole or in part, at any time or from time to time, in the Company's sole
discretion in the case of any Public Warrants tendered.

      9.       LOST, DESTROYED OR STOLEN CERTIFICATES.  If the certificate(s)
has (have) been lost, stolen or destroyed, check the box on the front of this
Letter of Transmittal and send the Letter of Transmittal to the Transfer Agent.
In such event, the Transfer Agent will forward an Affidavit of Loss and Bond of
Indemnity, which will require you to pay an insurance premium and a service
charge.  You are urged to properly complete and return documents immediately.

      10.      REQUESTS FOR ADDITIONAL COPIES.  Questions and requests for
additional copies of the Offering Circular and this Letter of Transmittal may
be directed to the Company at the address and telephone numbers set forth on
the last page of the Offering Circular.

      11.      SUBSTITUTE FORM W-9.  Each tendering warrant holder is required
to provide the Transfer Agent with a correct Taxpayer Identification Number
("TIN"), generally the warrant holder's social security or federal employer
identification number, on Substitute Form W-9 enclosed herewith.  If a warrant
holder fails to provide a TIN to the Transfer Agent, such warrant holder may be
subject to a $50 penalty imposed by the Internal Revenue Service.  The
"Certificate of Awaiting Taxpayer Identification Number" should be completed if
the tendering warrant holder has not been issued a TIN and has applied for a
number or intends to apply for a number in the near future.  If such
certificate is completed and the Transfer Agent is not provided with a TIN
within 60 days, the Transfer Agent will withhold 31% of all payments of cash
thereafter until a TIN is provided to the Transfer Agent.  The warrant holder
is required to give the Transfer Agent the social security number or employer
identification number of the record owner of the Public Warrants or of the last
transferee appearing on the stock powers attached to, or endorsed on, the
Public Warrants.  If the Public Warrants are in more than one name or is not in
the name of the actual owner, consult the enclosed Guidelines for Certification
of Taxpayer Identification Number on Substitute Form W-9 for additional
guidance on which number to report.

      IMPORTANT: THIS LETTER OF TRANSMITTAL OR A FACSIMILE COPY HEREOF
(TOGETHER WITH PUBLIC WARRANT CERTIFICATES OR CONFIRMATION OF BOOK-ENTRY
TRANSFER AND ALL OTHER REQUIRED DOCUMENTS) OR THE NOTICE OF GUARANTEED DELIVERY
MUST BE RECEIVED BY THE TRANSFER AGENT ON OR PRIOR TO THE EXPIRATION DATE.

                           IMPORTANT TAX INFORMATION

      Certain warrant holders (including, among others, all corporations and
certain foreign individuals) are not subject to backup withholding.  In order
for a foreign individual to qualify as an exempt recipient, that warrant holder
must submit a Form W-8, signed under penalties of perjury, attesting to that
individual's exempt status. A Form W-8 can be obtained from the Transfer Agent.
See the enclosed Guidelines for Certification of Taxpayer Identification Number
on Substitute Form W-9 for additional instructions.

      Backup withholding is not an additional tax.  Rather, the tax liability
of persons subject to backup withholding will be reduced by the amount of tax
withheld. If withholding results in an overpayment of taxes, a refund may be
obtained from the Internal Revenue Service.

[LETTERHEAD OF INTEGRATED SECURITY SYSTEMS, INC.]

February 26, 1998

Dear Warrant Holder:

Integrated Security Systems, Inc. is offering you the opportunity to exchange,
on a tax-free basis, warrants (the "Exchange Warrants") to purchase 2.1 shares
of the Company's common stock, par value $.01 per share (the "Common Stock"),
until April 20, 1999, at an exercise price of $3.17 per share of Common Stock
for the Company's currently outstanding Redeemable Common Stock Purchase
Warrants (the "Public Warrants").  The Public Warrants expire on April 20,
1998.

This Offer is for all of the Company's outstanding Public Warrants. Each
Exchange Warrant entitles the holder to purchase 2.1 shares of the Company's
Common Stock until April 20, 1999, at an exercise price of $3.17 per share of
Common Stock, subject to certain adjustments. The Exchange Warrants are
redeemable for $.25 per Exchange Warrant, at the option of the Company, upon 30
days' written notice. You may tender all or any portion of your Common Stock.

The purpose of the Company's offer to exchange the Public Warrants for the
Exchange Warrants is to (i) provide the holders of the outstanding Public
Warrants with a longer opportunity to profit from the exercise of the warrants,
(ii) modify the terms providing for the adjustment of the exercise price and
the number of shares purchasable upon exercise of the warrants to permit such
adjustments only upon the occurrence of stock splits, stock dividends,
recapitalizations or similar events, and (iii) permit the Company and the
Transfer Agent to modify the exercise price from time to time without obtaining
the consent of any of the holders of the Exchange Warrants.

The Company has concluded that the exchange qualifies as a tax-free
reorganization under the Internal Revenue Code of 1986. There are additional
tax issues which may affect tendering stockholders which are discussed fully in
the Offering Circular and as a result, offerees should consult their own tax
advisor concerning all tax consequences.

The Offer is being made to all the holders of the Public Warrants.  The Offer
will expire at midnight, New York City time, on April 17, 1998.

The Board of Directors of the Company has approved the making of the Offer but
is not making any recommendation to stockholders as to whether or not to tender
the Public Warrants. Each holder of Public Warrants must make his or her own
decision whether or not to tender his or her Public Warrants and, if so, how
many warrants to tender.

The Offer is explained in detail in the enclosed Offering Circular and Letter
of Transmittal. If you decide to tender all or part of your warrants, the
instructions on how to do this are contained in the enclosed materials.
Questions and requests for assistance with respect to the mechanics of the
Offer may be directed to the Company, at (972) 444-8280.

Sincerely,



Gerald K. Beckmann
President and
Chief Executive Officer

         INTEGRATED SECURITY SYSTEMS, INC. ANNOUNCES EXCHANGE OFFER:
                    EXCHANGE WARRANTS FOR PUBLIC WARRANTS

         IRVING, TEXAS (February 26, 1998) - Integrated Security Systems, Inc.
(Nasdaq: IZZI) announced today that it has commenced an offer to exchange new
Redeemable Common Stock Purchase Warrants (the "Exchange Warrants") in return
for the Company's currently outstanding Redeemable Common Stock Purchase
Warrants (the "Public Warrants"). Each Public Warrant accepted in the offer
will be exchanged for one Exchange Warrant.

         The offer is expected to qualify as a tax-free reorganization under
the Internal Revenue Code of 1986. The offer commences today and will expire at
midnight, New York City time, on April 17, 1998.

         Each Exchange Warrant to be issued in the offer entitles the holder to
purchase 2.1 shares of the Company's Common Stock until April 20, 1999, at an
exercise price of $3.17 per share of Common Stock, subject to certain
adjustments.  The Exchange Warrants are redeemable for $.25 per Exchange
Warrant, at the option of the Company, upon 30 days' written notice.

         The purpose of the Company's offer to exchange the Public Warrants for
the Exchange Warrants is to (i) provide the holders of the outstanding Public
Warrants with a longer opportunity to profit from the exercise of the warrants,
(ii) modify the terms providing for the adjustment of the exercise price and
the number of shares purchasable upon exercise of the warrants, and (iii)
permit the Company and the Transfer Agent to modify the exercise price from
time to time without obtaining the consent of any of the holders of the
Exchange Warrants.

         The exchange offer will be subject to various terms and conditions
described in offering materials to be distributed to warrant holders later this
week.

         The Board of Directors of the Company has approved the offer but is
not making any recommendation to warrant holders as to whether to tender Public
Warrants.  Each warrant holder should decide whether to tender warrants, and if
so, how many.

         Requests for further information about the offer may be directed to
the Company at (972) 444-8280.

         Headquartered in Irving, Texas, the Company is a developer,
manufacturer and national supplier of total security solutions for the
industrial and commercial marketplaces. The Company is also a leading supplier
of automatic gates and lane changers to the U.S. road and bridge industry. The

Warrant, the date of this Agreement.

         (e)     "Purchase Price" shall mean the price to be paid for each

to all Warrantholders, the Company shall have the right to extend the Warrant
Expiration Date.


         SECTION 2.       Warrants and Issuance of Warrant Certificates.

         (a)     Each Warrant shall initially entitle the Registered Holder of
the Warrant Certificate representing such Warrant to purchase 2.1 shares of

         (b)     Upon execution of this Agreement and thereafter, Warrant
Certificates representing the number of Warrants exchanged pursuant to the
Exchange Offer shall be executed by the Company and delivered to the Warrant
Agent.  Upon written order of the Company signed by its President or Chairman

Certificates shall be countersigned, issued and delivered by the Warrant Agent
to the holders of IPO Warrants that have exchanged such IPO Warrants pursuant
to the Exchange Offer.

         (c)     From time to time, up to the Warrant Expiration Date, the
Transfer Agent shall countersign and deliver stock certificates in required

of Warrants in accordance with this Agreement.

         (d)     From time to time, up to the Warrant Expiration Date, the
Warrant Agent shall countersign and deliver Warrant Certificates in required
whole number denominations to the persons entitled thereto in connection with
any transfer or exchange permitted under this Agreement; provided that no
Warrant Certificates shall be issued except (i) those initially issued
hereunder, (ii) those issued upon the exercise of fewer than all Warrants
represented by any Warrant Certificate, to evidence any unexercised Warrants
held by the exercising Registered Holder, (iii) those issued upon any transfer
or exchange pursuant to Section 6; (iv) those issued in replacement of lost,
stolen, destroyed or mutilated Warrant Certificates pursuant to Section 7; and
(v) at the option of the Company, in such form as may be approved by its Board
of Directors, to reflect any adjustment or change in the Purchase Price, the
number of shares of Common Stock purchasable upon exercise of the Warrants or
the Redemption Price therefor made pursuant to Section 9 or Section 10 hereof.


         SECTION 3.       Form and Execution of Warrant Certificates.

         (a)     The Warrant Certificates shall be substantially in the form
annexed hereto as Exhibit A and may have such letters, numbers or other marks
of identification or designation and such legends, summaries or endorsements
printed, lithographed or engraved thereon as the Company may deem appropriate
and as are not inconsistent with the provisions of this Agreement or as may be
required to comply with any law or with any rule or regulation made pursuant
thereto or with any rule or regulation of any stock exchange on which the
Warrants may be listed, or to conform to usage.  The Warrant Certificates shall
be dated the date of issuance thereof (whether upon initial issuance, transfer,
exchange or in lieu of mutilated, lost, stolen, or destroyed Warrant
Certificates) and issued in registered form.  Warrants shall be numbered
serially with the letter W on the Warrants.

         (b)     Warrant Certificates shall be executed on behalf of the
Company by its Chairman of the Board, President or any Vice President and by
its Secretary or an Assistant Secretary, by manual signatures or by facsimile
signatures printed thereon, and shall have imprinted thereon a facsimile of the
Company's seal.  Warrant Certificates shall be manually countersigned by the
Warrant Agent and shall not be valid for any purpose unless so countersigned.
In case any officer of the Company who shall have signed any of the Warrant
Certificates shall cease to be such officer of the Company before the date of
issuance of the Warrant Certificates or before countersignature by the Warrant
Agent and issue and delivery





                                       3
<PAGE>   4
thereof, such Warrant Certificates may nevertheless be countersigned by the
Warrant Agent, issued and delivered with the same force and effect as though
the person who signed such Warrant Certificates had not ceased to be such
officer of the Company.  After countersignature by the Warrant Agent, Warrant
Certificates shall be delivered by the Warrant Agent to the Registered Holder
without further action by the Company.


         SECTION 4.       Exercise.  Each Warrant may be exercised by the
Registered Holder thereof at any time on or after the date hereof, but not
after the Warrant Expiration Date, upon the terms and subject to the conditions
set forth herein and in the applicable Warrant Certificate.  A Warrant shall be
deemed to have been exercised immediately prior to the close of business on the
Exercise Date and the person entitled to receive the securities deliverable
upon such exercise shall be treated for all purposes as the holder upon
exercise thereof as of the close of business on the Exercise Date.  As soon as
practicable on or after the Exercise Date the Warrant Agent shall deposit the
proceeds received from the exercise of a Warrant and shall notify the Company
in writing of the exercise of the Warrants.  Promptly following, and in any
event within five days after the date of such notice from the Warrant Agent,
the Warrant Agent, on behalf of the Company, shall cause to be issued and
delivered by the Transfer Agent, to the person or persons entitled to receive
the same, a certificate or certificates for the securities deliverable upon
such exercise (plus a Warrant Certificate for any remaining unexercised
Warrants of the Registered Holder), unless prior to the date of issuance of
such certificates the Company shall instruct the Warrant Agent to refrain from
causing such issuance of certificates pending clearance of checks received in
payment of the Purchase Price pursuant to such Warrants.  Upon the exercise of
any Warrant and clearance of the funds received, the Warrant Agent shall
promptly remit the payment received for the Warrant to the Company or as the
Company may direct in writing.


         SECTION 5.       Reservation of Shares; Listing; Payment of Taxes;
Etc.

         (a)     The Company covenants that it will at all times reserve and
keep available out of its authorized Common Stock, solely for the purpose of
issue upon exercise of Warrants, such number of shares of Common Stock as shall
then be issuable upon the exercise of all outstanding Warrants.  The Company
covenants that all shares of Common Stock which shall be issuable upon exercise
of the Warrants shall, at the time of delivery, be duly and validly issued,
fully paid, nonassessable and free from all taxes, liens and charges with
respect to the issue thereof (other than those which the Company shall promptly
pay or discharge) and that upon issuance such shares shall be listed on each
national securities exchange, if any, on which the other shares of outstanding
Common Stock of the Company are then listed.

         (b)     The Company covenants that if any securities to be reserved
for the purpose of exercise of Warrants hereunder require registration with, or
approval of, any governmental authority under any federal securities law before
such securities may be validly issued or delivered upon such exercise, then the
Company will in good faith and as expeditiously as reasonably possible,
endeavor to secure such registration or approval.  The Company will use
reasonable efforts to obtain appropriate approvals or registrations under state
"blue sky" securities laws with respect to any such securities.  However,
Warrants may not be exercised





                                       4
<PAGE>   5
by, or shares of Common Stock issued to, any Registered Holder in any state in
which such exercise would be unlawful.

         (c)     The Company shall pay all documentary, stamp or similar taxes
and other governmental charges that may be imposed upon the Company with
respect to the issuance of Warrants, or the issuance or delivery of any shares
upon exercise of the Warrants; provided, however, that if the shares of Common
Stock are to be delivered in a name other than the name of the Registered
Holder of the Warrant Certificate representing any Warrant being exercised,
then no such delivery shall be made unless the person requesting the same has
paid to the Warrant Agent the amount of transfer taxes or charge incident
thereto, if any.

         (d)     The Warrant Agent is hereby irrevocably authorized to
requisition the Company's Transfer Agent from time to time for certificates
representing shares of Common Stock required upon exercise of the Warrants, and
the Company will authorize the Transfer Agent to comply with all such proper
requisitions.  The Company will file with the Warrant Agent a statement setting
forth the name and address of the Transfer Agent of the Company for shares of
Common Stock issuable upon exercise of the Warrants, unless the Warrant Agent
and the Transfer Agent are the same entity.


         SECTION 6.       Exchange and Registration of Transfer.

         (a)     Warrant Certificates may be exchanged for other Warrant
Certificates representing an equal aggregate number of Warrants, of the same
class or may be transferred in whole or in part.  Warrant Certificates to be
exchanged shall be surrendered to the Warrant Agent at its Corporate Office,
and upon satisfaction of the terms and provisions hereof, the Company shall
execute and the Warrant Agent shall countersign, issue and deliver in exchange
therefor the Warrant Certificate or Certificates which the Registered Holder
making the exchange shall be entitled to receive.

         (b)     The Warrant Agent shall keep at its Corporate Office books in
which, subject to such reasonable regulations as it may prescribe, it shall
register Warrant Certificates and the transfer thereof in accordance with its
regular practice.  Upon due presentment for registration of transfer of any
Warrant Certificate at such Corporate Office, the Company shall execute and the
Warrant Agent shall issue and deliver to the transferee or transferees a new
Warrant Certificate or Certificates representing an equal aggregate number of
Warrants of the same class.

         (c)     With respect to all Warrant Certificates presented for
registration or transfer, or for exchange or exercise, the subscription form on
the reverse thereof shall be duly endorsed, or be accompanied by a written
instrument or instruments of transfer and subscription, in form satisfactory to
the Company and the Warrant Agent, duly executed by the Registered Holder or
his attorney-in-fact duly authorized in writing.

         (d)     A service charge may be imposed by the Warrant Agent for any
exchange or registration of transfer of Warrant Certificates.  In addition, the
Company may require payment by such holder of a sum sufficient to cover any tax
or other governmental charge that may be imposed in connection therewith.





                                       5
<PAGE>   6
         (e)     All Warrant Certificates surrendered for exercise or for
exchange in case of mutilated Warrant Certificates shall be promptly canceled
by the Warrant Agent and thereafter retained by the Warrant Agent until
termination of this Agreement or resignation as Warrant Agent, or disposed of
or destroyed, at the direction of the Company.

         (f)     Prior to due presentment for registration of transfer thereof,
the Company and the Warrant Agent may deem and treat the Registered Holder of
any Warrant Certificate as the absolute owner thereof and of each Warrant
represented thereby (notwithstanding any notations of ownership or writing
thereon made by anyone other than a duly authorized officer of the Company or
the Warrant Agent) for all purposes and shall not be affected by any notice to
the contrary.


         SECTION 7.       Loss or Mutilation. Upon receipt by the Company and
the Warrant Agent of evidence satisfactory to them of the ownership of and
loss, theft, destruction or mutilation of any Warrant Certificate and (in case
of loss, theft or destruction) of indemnity satisfactory to them, and (in the
case of mutilation) upon surrender and cancellation thereof, the Company shall
execute and the Warrant Agent shall (in the absence of notice to the Company
and/or Warrant Agent that the Warrant Certificate has been acquired by a bona
fide purchaser) countersign and deliver to the Registered Holder in lieu
thereof a new Warrant Certificate of like tenor representing an equal aggregate
number of Warrants.  Applicants for a substitute Warrant Certificate shall
comply with such other reasonable regulations and pay such other reasonable
charges as the Warrant Agent may prescribe.


         SECTION 8.       Redemption.

         (a)     Commencing as of the date of this Agreement, on not less than
thirty (30) days' prior written notice, the Warrants may be redeemed by the
Company, at the option of the Company, at a redemption price of $0.25 per
Warrant.  All Warrants must be redeemed if any of the Warrants are redeemed.

         (b)     If the Company shall desire to exercise its right to so redeem
the Warrants, it shall request the Warrant Agent to mail a notice of redemption
to each of the Registered Holders of the Warrants to be redeemed, first class,
postage prepaid, not later than the thirtieth day before the date fixed for
redemption, at their last address as shall appear on the records of the Warrant
Agent.  Any notice mailed in the manner provided herein shall be conclusively
presumed to have been duly given whether or not the Registered Holder receives
such notice.

         (c)     The notice of redemption shall specify (i) the redemption
price, (ii) the date fixed for redemption, (iii) the place where the Warrant
Certificates shall be delivered, (iv) the redemption price to be paid and (v)
that the right to exercise the Warrant shall terminate at 5:00 p.m. (New York
City time) on the close of business on the date for redemption fixed in the
notice.  The date fixed for the redemption of the Warrants that have been
called for redemption shall be the Redemption Date.  No failure to mail such
notice nor any defect therein or in the mailing thereof shall affect the
validity of the proceedings for such redemption except as to a holder (a) to
whom notice was not mailed or (b) whose notice was





                                       6
<PAGE>   7
defective.  An affidavit of the Warrant Agent or of the Secretary or an
Assistant Secretary of the Company that notice of redemption has been mailed
shall, in the absence of fraud, be prima facie evidence of the facts stated
therein.

         (d)     Any right to exercise a Warrant that has been called for
redemption shall terminate at 5:00 p.m. (New York City time) on the close of
business on the date for redemption fixed in the notice.  On and after the
Redemption Date, Holders of the redeemed Warrants shall have no further rights
except to receive, upon surrender of the redeemed Warrant, the Redemption
Price.

         (e)     From and after the date specified for redemption, the Company
shall, at the place specified in the notice of redemption, upon presentation
and surrender to the Company by or on behalf of the Registered Holder thereof
of one or more Warrants to be redeemed, deliver or cause to be delivered to or
upon the written order of such Holder a sum in cash equal to the redemption
price of each such Warrant.  From and after the date fixed for redemption and
upon the deposit or setting aside by the Company of a sum sufficient to redeem
all the Warrants called for redemption, such Warrants shall expire and become
void and all rights hereunder and under the Warrant Certificates, except the
right to receive payment of the redemption price, shall cease.


         SECTION 9.       Adjustment of Exercise Price and Number of Shares of
Common Stock or Warrants on or Before April 20, 1998.  On or before April 20,
1998, the provisions of this Section 9 shall apply:

         (a)     Subject to the exceptions referred to in Section 9(g) below,
in the event the Company shall, at any time or from time to time prior to or on
April 20, 1998, (i) sell any shares of Common Stock for a consideration per
share less than the then current Purchase Price, (ii) issue any shares of
Common Stock as a stock dividend to the holders of Common Stock, or (iii)
subdivide or combine the outstanding shares of Common Stock into a greater or
lesser number of shares (any such sale, issuance, subdivision or combination
being herein called a "Prior Change of Shares"), then, and thereafter upon each
further Prior Change of Shares, the applicable Purchase Price in effect
immediately prior to such Prior Change of Shares shall be changed to a price
(including any applicable fraction of a cent) determined by multiplying the
Purchase Price in effect immediately prior thereto by a fraction, the numerator
of which shall be the sum of (a) the total number of shares of Common Stock
outstanding immediately prior to such Prior Change of Shares and (b) the number
of shares of Common Stock which the aggregate consideration received by the
Company upon such sale, issuance, subdivision or combination could have
purchased at the then current Purchase Price, and the denominator of which
shall be the total number of shares of Common Stock outstanding immediately
after such Prior Change of Shares.

         Upon each adjustment of the applicable Purchase Price pursuant to this
Section 9, the total number of shares of Common Stock purchasable upon the
exercise of each Warrant shall (subject to the provisions contained in Section
9(b) hereof) be such number of shares (calculated to the nearest tenth)
purchasable at the applicable Purchase Price immediately prior to such
adjustment multiplied by a fraction, the numerator of which shall be the
applicable Purchase Price in effect immediately prior to such adjustment and
the





                                       7
<PAGE>   8
denominator of which shall be the applicable Purchase Price in effect
immediately after such adjustment.

         (b)     The Company may elect, upon any adjustment of the applicable
Purchase Price pursuant to this Section 9, to adjust the number of Warrants
outstanding, in lieu of adjusting the number of shares of Common Stock
purchasable upon the exercise of each Warrant as hereinabove provided, so that
each Warrant outstanding after such adjustment shall represent the right to
purchase one share of Common Stock.  Each Warrant held of record prior to such
adjustment of the number of Warrants shall become that number of Warrants
(calculated to the nearest tenth) determined by multiplying the number one by a
fraction, the numerator or which shall be the applicable Purchase Price in
effect immediately prior to such adjustment and the denominator of which shall
be the applicable Purchase Price in effect immediately after such adjustment.
Upon each such adjustment of the number of Warrants, the Redemption Price in
effect immediately prior to such adjustment also shall be adjusted by
multiplying such Redemption Price by a fraction, the numerator of which shall
be the Purchase Price in effect immediately after such adjustment and the
denominator of which shall be the Purchase Price in effect immediately prior to
such adjustment.  Upon each adjustment of the number of Warrants pursuant to
this Section 9, the Company shall, as promptly as practicable, cause to be
distributed to each Registered Holder of Warrant Certificates on the date of
such adjustment Warrant Certificates evidencing, subject to Section 11 hereof,
the number of additional Warrants, if any, to which such Holder shall be
entitled as a result of such adjustment or, at the option of the Company, cause
to be distributed to such Holder in substitution and replacement for the
Warrant Certificates held by him prior to the date of adjustment (and upon
surrender thereof, if required by the Company) new Warrant Certificates
evidencing the number of Warrants to which such Holder shall be entitled after
such adjustment.

         (c)     In case of any reclassification, capital reorganization or
other change of outstanding shares of Common Stock, or in case of any
consolidation or merger of the Company with or 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, capital
reorganization or other change of outstanding shares of Common Stock), or in
case of any sale or conveyance to another corporation of the property of the
Company as, or substantially as, an entirety (other than a sale/leaseback,
mortgage or other financing transaction), the Company shall cause effective
provision to be made so that each holder of a Warrant then outstanding shall
have the right thereafter, by exercising such Warrant, to purchase the kind and
number of shares of stock or other securities or property (including cash)
receivable upon such reclassification, capital reorganization, or other change,
consolidation, merger, sale or conveyance by a holder of the number of shares
of Common Stock that might have been purchased upon exercise of such Warrant,
immediately prior to such reclassification, capital reorganization or other
change, consolidation, merger, sale or conveyance.  Any such provision shall
include provision for adjustments that shall be as nearly equivalent as may be
practicable to the adjustments provided for in this Section 9. The foregoing
provisions shall similarly apply to successive reclassifications, capital
reorganizations and other changes of outstanding shares of Common Stock and to
successive consolidations, mergers, sales or conveyances.

         (d)     Irrespective of any adjustments or changes in the Purchase
Price or the number of shares of Common Stock purchasable upon exercise of the
Warrants, the Warrant Certificates theretofore and thereafter issued shall,
unless the Company shall exercise its option to issue new Warrant Certificates
pursuant to Section 2(d) hereof, continue to express the applicable Purchase
Price per share, the number of shares purchasable thereunder and the Redemption
Price therefor as the Purchase Price per share, and the number of shares
purchasable thereunder and the Redemption Price therefor were expressed in the
Warrant Certificates when the same were originally issued.

         (e)     After each adjustment of the Purchase Price pursuant to this
Section 9, the Company will promptly prepare a certificate signed by the
Chairman or President, and by the Treasurer of an Assistant Treasurer or the
Secretary or an Assistant Secretary, of the Company setting forth: (i) the
applicable Purchase Price as so adjusted, (ii) the number of shares of Common
Stock purchasable upon exercise of each Warrant after such adjustment, and, if
the Company shall have elected to adjust the number of Warrants to which the
registered holder of each Warrant shall then be entitled, and the adjustment in
Redemption Price resulting therefrom and (iii) a brief statement of the facts
accounting for such adjustment.  The Company will promptly file such
certificate with the Warrant Agent and cause a brief summary thereof to be sent
by ordinary first class mail to each Registered Holder of Warrants at his last
address as it shall appear on the registry books of the Warrant Agent.  No
failure to mail such notice nor any defect therein or in the mailing thereof
shall affect the validity thereof except as to the holder to whom the Company
failed to mail such notice, or except as to the holder whose notice was
defective.  The affidavit of an officer of the Warrant Agent or the Secretary
or an Assistant Secretary of the Company that such notice has been mailed
shall, in the absence of fraud, be prima facie evidence of the facts stated
therein.

         (f)     For purposes of Section 9(a) and 9(b) hereof, the following
provisions (i) through (vi) shall also be applicable:

                 (i)      The number of shares of Common Stock outstanding at
         any given time shall include shares of Common Stock owned or held by
         or for the account of the Company, and the sale or issuance of such
         treasury shares or the distribution of any such treasury shares shall
         not be considered a Prior Change of Shares for purposes of said
         sections.

                 (ii)     No adjustment of the Purchase Price shall be made
         unless such adjustment would require an increase or decrease of at
         least $.05 in such price; provided that any adjustments which by
         reason of this clause (ii) are not required to be made shall be
         carried forward and shall be made at the time of and together with the
         next subsequent adjustment which, together with any adjustment(s) so
         carried forward, shall require an increase or decrease of at least
         $.05 in the Purchase Price then in effect hereunder.

                 (iii)    In case of (1) the sale by the Company solely for
         cash of any rights or warrants to subscribe for or purchase, or any
         options for the purchase of, Common Stock or any securities
         convertible into or exchangeable for Common Stock without the payment
         of any further consideration other than cash, if any (such convertible
         or

         exchangeable securities being herein called "Convertible Securities"),
         or (2) the issuance by the Company, without the receipt by the Company
         of any consideration therefor, of any rights or warrants to subscribe
         for or purchase, or any options for the purchase of, Common stock or
         Convertible Securities, in each case, if (and only if) the
         consideration payable to the Company upon the exercise of such rights,
         warrants or options shall consist solely of cash, whether or not such
         rights, warrants or options, or the right to convert or exchange such
         Convertible Securities, are immediately exercisable, and the price per
         share for which Common Stock is issuable upon the exercise of such
         rights, warrants or options or upon the conversion or exchange of such
         Convertible Securities (determined by dividing (x) the minimum
         aggregate consideration payable to the Company upon the exercise of
         such rights, warrants or options, plus the consideration received by
         the Company for the issuance or sale of such rights, warrants or
         options, plus, in the case of such Convertible Securities, the minimum
         aggregate amount of additional consideration, if any, other than such
         Convertible Securities, payable upon the conversion or exchange
         thereof, by (y) the total maximum number of shares of Common Stock
         issuable upon the exercise of such rights, warrants or options or upon
         the conversion or exchange of such Convertible Securities issuable
         upon the exercise of such rights, warrants or options) is less than
         the then Purchase Price immediately prior to the date of the sale of
         such Convertible Securities, then the total maximum number of shares
         of Common Stock issuable upon the conversion or exchange of such
         Convertible Securities (as of the date of the sale of such Convertible
         Securities) shall be deemed to be outstanding shares of Common Stock
         for purposes of Sections 9(a) and 9(b) hereof and shall be deemed to
         have been sold for cash in an amount equal to such price per share.

                 (iv)     In case of the sale by the Company solely for cash of
         any Convertible Securities, whether or not the right of conversion or
         exchange thereunder is immediately exercisable, and the price per
         share for which Common Stock is issuable upon the conversion or
         exchange of such Convertible Securities (determined by dividing the
         total amount of consideration received by the Company for the sale of
         such Convertible Securities, plus the minimum aggregate amount of
         additional consideration, if any, other than such Convertible
         Securities, payable upon the conversion or exchange thereof, by (y)
         the total maximum number of shares of Common Stock issuable the
         conversion or exchange of such Convertible Securities) is less than
         the then Purchase Price immediately prior to the date of the issuance
         or sale of such Convertible Securities; then the total maximum number
         of shares of Common Stock issuable upon the exercise of such
         Convertible Securities (as of the date of the issuance or sale of such
         Convertible Securities) shall be deemed to be outstanding shares of
         Common Stock for purposes of Sections 9(a) and 9(b) hereof and shall
         be deemed to have been sold for cash in an amount equal to such price
         per share.

                 (v)      If the exercise or purchase price provided for in any
         right, warrant or option referred to in (iii) above, or the rate at
         which any Convertible Securities referred to in (iii) or (iv) above
         are convertible into or exchangeable for Common Stock, shall change at
         any time (other than under or by reason of provisions designed to
         protect against dilution), the Purchase Price then in effect hereunder
         shall forthwith be readjusted to such Purchase Price as would have
         been obtained (1) had the adjustments made upon the issuance or sale
         of such rights, warrants, options or





                                       10
<PAGE>   11
         Convertible Securities been made upon the basis of the issuance of
         only the number of shares of Common Stock theretofore actually
         delivered (and the total consideration received therefor) upon the
         exercise of such rights, warrants or options or upon the conversion or
         exchange of such Convertible Securities, (2) had adjustments been made
         on the basis of the Purchase Price as adjusted under clause (1) for
         all transactions (which would have affected such adjusted Purchase
         Price) made after the issuance or sale of such rights, warrants,
         options or Convertible Securities, and (3) had any such rights,
         warrants, options or Convertible Securities then still outstanding
         been originally issued or sold at the time of such change.  On the
         expiration of any such right, warrant or option or the termination of
         any such right to convert or exchange any such Convertible Securities,
         the Purchase Price then in effect hereunder shall forthwith be
         readjusted to such Purchase Price as would have been obtained (a) had
         the adjustments made upon the issuance or sale of such rights,
         warrants, options or Convertible Securities been made upon the basis
         of the issuance of only the number of shares of Common Stock
         theretofore actually delivered (and the total consideration received
         therefor) upon the exercise of such rights, warrants or options or
         upon the conversion or exchange of such Convertible Securities and (b)
         had adjustments been made on the basis of the Purchase Price as
         adjusted under clause (a) for all transactions (which would have
         affected such adjusted Purchase Price) made after the issuance or sale
         of such rights, warrants, options or Convertible Securities.

                 (vi)     In case of the sale for cash of any shares of Common
         Stock, any Convertible Securities, any rights or warrants to subscribe
         for or purchase, or any options for the purchase of, Common Stock or
         Convertible Securities, the consideration received by the Company
         therefore shall be deemed to be the gross sales price therefor without
         deducting therefrom any expense paid or incurred by the Company or any
         underwriting discounts or commissions or concessions paid or allowed
         by the Company in connection therewith.  Notwithstanding anything
         contained herein to the contrary, no adjustment in the Purchase Price
         shall be made until the number of shares of Common Stock or
         Convertible Securities issued by the Company exceeds five percent (5%)
         of the number of shares of Common Stock outstanding as of the date of
         this Agreement.

         (g)     No adjustment to the Purchase Price of the Warrants or to the
number of shares of Common Stock purchasable upon the exercise of each Warrant
will be made pursuant to this Section 9, however,

                 (i)      upon the grant or exercise of any options or warrants
         outstanding on the date hereof or options which may hereafter be
         granted or exercised under any stock option plan of the Company as
         described in the Registration Statement; or

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

                 (iii)    upon the issuance or sale of Common Stock or
         Convertible Securities upon the exercise of any rights or warrants to
         subscribe for or purchase, or any options for the purchase of, Common
         Stock or Convertible Securities, whether or not such rights, warrants
         or options were outstanding on the date of the original sale of the
         IPO Warrants or issuance of the Warrants or were thereafter issued or
         sold; or





                                       11
<PAGE>   12
                 (iv)     upon the issuance or sale of Common Stock upon
         conversion or exchange of any Convertible Securities, whether or not
         any adjustment in the Purchase Price was made or required to be made
         upon the issuance or sale of such Convertible Securities and whether
         or not such Convertible Securities were outstanding on the date of the
         original sale of the IPO Warrants or the date of this Agreement or
         were thereafter issued or sold; or

                 (v)      upon any amendment to or change in the terms of any
         rights or warrants to subscribe for or purchase, or options for the
         purchase of, Common Stock or Convertible Securities or in the terms of
         any 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 (other than
         rights, warrants, options or Convertible Securities issued or sold
         after the close of business on the date of this Agreement (i) for
         which an adjustment in the Purchase Price then in effect was
         theretofore made or required to be made, upon the issuance or sale
         thereof, or (ii) for which such an adjustment would have been required
         had the exercise or purchase price of such rights, warrants or options
         at the time of the issuance or sale thereof or the rate of conversion
         or exchange of such Convertible Securities, at the time of the sale of
         such Convertible Securities, or the issuance or sale of rights or
         warrants to subscribe for or purchase, or options for the purchase of,
         such Convertible Securities, been the price or rate as changed, in
         which case the provisions of Section 9(f)(v) hereof shall be
         applicable if, but only if, the exercise or purchase price thereof, as
         changed, or the rate of conversion or exchange thereof, as changed,
         consists solely of cash or requires the payment of additional
         consideration, if any, consisting solely of cash and the Company did
         not receive any consideration other than cash, if any, in connection
         with such change).

         (h)     As used in this Section 9, the term "Common Stock" shall mean
and include the Company's Common Stock authorized on the date of the original
issue of the Units and shall also include any capital stock of any class of the
Company thereafter authorized which shall not be limited to a fixed sum or
percentage in respect of the rights of the holders thereof to participate in
dividends and in the distribution of assets upon the voluntary liquidation,
dissolution or winding up of the Company; provided, however, that the shares
issuable upon exercise of the Warrants shall include only shares of such class
designated in the Company's Certificate of Incorporation as Common Stock on the
date of the original issue of the Units or (i), in the case of any
reclassification, change, consolidation, merger, sale or conveyance of the
character referred to in Section 9(c) hereof, the stock securities or property
provided for in such section or (ii), in the case of any reclassification or
change in the outstanding shares of Common Stock issuable upon exercise of the
Warrants as a result of a subdivision or combination or consisting of a change
in par value, or from par value to no par value, or from no par value to par
value, such shares of Common Stock as so reclassified or changed.





                                       12

         (i)     Any determination as to whether an adjustment in the Purchase
Price in effect hereunder is required pursuant to this Section 9, or as to the
amount of any such adjustment, if required, shall be binding upon the holders
of the Warrants and the Company if made in good faith by the Board of Directors
of the Company.

         (j)     If and whenever the Company shall grant to the holders of
Common Stock, as such, rights or warrants to subscribe for or to purchase, or
any options for the purchase of, Common Stock or securities convertible into or
exchangeable for or carrying a right, warrant or option to purchase Common
Stock, the Company shall concurrently therewith grant to each of the then
Registered Holders of the Warrants all of such rights, warrants or options to
which each such holder would have been entitled if, on the date of
determination of stockholders entitled to the rights, warrants or options being
granted by the Company, such holder were the holder of record of the number of
whole shares of Common Stock then issuable upon exercise (assuming, for
purposes of this Section 9(j), that exercise of Warrants is permissible during
periods prior to the Initial Warrant Exercise Date) of his Warrants.  Such
grant by the Company to the holders of the Warrants shall be in lieu of any
adjustment which otherwise might be called for pursuant to this Section 9.

         SECTION 10.      Adjustment of Exercise Price and Number of Shares of
Common Stock or Warrants After April 20, 1998.  After April 20, 1998, the
provisions of Section 9 shall be inapplicable, and the provisions of this
Section 10 shall apply:

         (a)     In the event the Company shall, at any time or from time to
time after April 20, 1998, (i) issue any shares of Common Stock as a stock
dividend to the holders of Common Stock or (ii) subdivide or combine the
outstanding shares of Common Stock into a greater or lesser number of shares
(any such issuance, subdivision or combination being herein called a
"Subsequent Change of Shares"), then, and thereafter upon each further
Subsequent Change of Shares, the applicable Purchase Price in effect
immediately prior to such Subsequent Change of Shares shall be proportionately
adjusted.

         Upon each adjustment of the applicable Purchase Price pursuant to this
Section 10, the total number of shares of Common Stock purchasable upon the
exercise of each Warrant shall (subject to the provisions contained in Section
10(b) hereof) be such number of shares (calculated to the nearest tenth)
purchasable at the applicable Purchase Price immediately prior to such
adjustment multiplied by a fraction, the numerator of which shall be the
applicable Purchase Price in effect immediately prior to such adjustment and
the denominator of which shall be the applicable Purchase Price in effect
immediately after such adjustment.

         (b)     The Company may elect, upon any adjustment of the applicable
Purchase Price pursuant to this Section 10, to adjust the number of Warrants
outstanding, in lieu of adjusting the number of shares of Common Stock
purchasable upon the exercise of each Warrant as hereinabove provided, so that
each Warrant outstanding after such adjustment shall represent the right to
purchase one share of Common Stock.  Each Warrant held of record prior to such
adjustment of the number of Warrants shall become that number of Warrants
(calculated to the nearest tenth) determined by multiplying the number one by a
fraction, the numerator or which shall be the applicable Purchase Price in
effect immediately





                                       13
<PAGE>   14
prior to such adjustment and the denominator of which shall be the applicable
Purchase Price in effect immediately after such adjustment.  Upon each such
adjustment of the number of Warrants, the Redemption Price in effect
immediately prior to such adjustment also shall be adjusted by multiplying such
Redemption Price by a fraction, the numerator of which shall be the Purchase
Price in effect immediately after such adjustment and the denominator of which
shall be the Purchase Price in effect immediately prior to such adjustment.
Upon each adjustment of the number of Warrants pursuant to this Section 10, the
Company shall, as promptly as practicable, cause to be distributed to each
Registered Holder of Warrant Certificates on the date of such adjustment
Warrant Certificates evidencing, subject to Section 11 hereof, the number of
additional Warrants, if any, to which such Holder shall be entitled as a result
of such adjustment or, at the option of the Company, cause to be distributed to
such Holder in substitution and replacement for the Warrant Certificates held
by him prior to the date of adjustment (and upon surrender thereof, if required
by the Company) new Warrant Certificates evidencing the number of Warrants to
which such Holder shall be entitled after such adjustment.

         (c)     In case of any reclassification, capital reorganization or
other change of outstanding shares of Common Stock, or in case of any
consolidation or merger of the Company with or 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, capital
reorganization or other change of outstanding shares of Common Stock), or in
case of any sale or conveyance to another corporation of the property of the
Company as, or substantially as, an entirety (other than a sale/leaseback,
mortgage or other financing transaction), the Company shall cause effective
provision to be made so that each holder of a Warrant then outstanding shall
have the right thereafter, by exercising such Warrant, to purchase the kind and
number of shares of stock or other securities or property (including cash)
receivable upon such reclassification, capital reorganization, or other change,
consolidation, merger, sale or conveyance by a holder of the number of shares
of Common Stock that might have been purchased upon exercise of such Warrant,
immediately prior to such reclassification, capital reorganization or other
change, consolidation, merger, sale or conveyance.  Any such provision shall
include provision for adjustments that shall be as nearly equivalent as may be
practicable to the adjustments provided for in this Section 10. The foregoing
provisions shall similarly apply to successive reclassifications, capital
reorganizations and other changes of outstanding shares of Common Stock and to
successive consolidations, mergers, sales or conveyances.

         (d)     Irrespective of any adjustments or changes in the Purchase
Price or the number of shares of Common Stock purchasable upon exercise of the
Warrants, the Warrant Certificates theretofore and thereafter issued shall,
unless the Company shall exercise its option to issue new Warrant Certificates
pursuant to Section 2(d) hereof, continue to express the applicable Purchase
Price per share, the number of shares purchasable thereunder and the Redemption
Price therefor as the Purchase Price per share, and the number of shares
purchasable thereunder and the Redemption Price therefor were expressed in the
Warrant Certificates when the same were originally issued.





                                       14
<PAGE>   15
         (e)     After each adjustment of the Purchase Price pursuant to this
Section 10, the Company will promptly prepare a certificate signed by the
Chairman or President, and by the Treasurer of an Assistant Treasurer or the
Secretary or an Assistant Secretary, of the Company setting forth: (i) the
applicable Purchase Price as so adjusted, (ii) the number of shares of Common
Stock purchasable upon exercise of each Warrant after such adjustment, and, if
the Company shall have elected to adjust the number of Warrants to which the
registered holder of each Warrant shall then be entitled, and the adjustment in
Redemption Price resulting therefrom and (iii) a brief statement of the facts
accounting for such adjustment.  The Company will promptly file such
certificate with the Warrant Agent and cause a brief summary thereof to be sent
by ordinary first class mail to each Registered Holder of Warrants at his last
address as it shall appear on the registry books of the Warrant Agent.  No
failure to mail such notice nor any defect therein or in the mailing thereof
shall affect the validity thereof except as to the holder to whom the Company
failed to mail such notice, or except as to the holder whose notice was
defective.  The affidavit of an officer of the Warrant Agent or the Secretary
or an Assistant Secretary of the Company that such notice has been mailed
shall, in the absence of fraud, be prima facie evidence of the facts stated
therein.

         (f)     For purposes of Section 10(a) and 10(b) hereof, the following
provisions (i) through (vi) shall also be applicable:

                 (i)      The number of shares of Common Stock outstanding at
         any given time shall include shares of Common Stock owned or held by
         or for the account of the Company, and the sale or issuance of such
         treasury shares or the distribution of any such treasury shares shall
         not be considered a Subsequent Change of Shares for purposes of said
         sections.

                 (ii)     No adjustment of the Purchase Price shall be made
         unless such adjustment would require an increase or decrease of at
         least $.05 in such price; provided that any adjustments which by
         reason of Section 9(f)(ii) or this clause (ii) are not required to be
         made shall be carried forward and shall be made at the time of and
         together with the next subsequent adjustment which, together with any
         adjustment(s) so carried forward, shall require an increase or
         decrease of at least $.05 in the Purchase Price then in effect
         hereunder.

         (g)     As used in this Section 10, the term "Common Stock" shall mean
and include the Company's Common Stock authorized on the date of the original
issue of the Units and shall also include any capital stock of any class of the
Company thereafter authorized which shall not be limited to a fixed sum or
percentage in respect of the rights of the holders thereof to participate in
dividends and in the distribution of assets upon the voluntary liquidation,
dissolution or winding up of the Company; provided, however, that the shares
issuable upon exercise of the Warrants shall include only shares of such class
designated in the Company's Certificate of Incorporation as Common Stock on the
date of the original issue of the Units or (i), in the case of any
reclassification, change, consolidation, merger, sale or conveyance of the
character referred to in Section 10(c) hereof, the stock securities or property
provided for in such section or (ii), in the case of any reclassification or
change in the outstanding shares of Common Stock issuable upon exercise of the
Warrants as a result of a subdivision





                                       15

or combination or consisting of a change in par value, or from par value to no
par value, or from no par value to par value, such shares of Common Stock as so
reclassified or changed.

         (h)     Any determination as to whether an adjustment in the Purchase
Price in effect hereunder is required pursuant to this Section 10, or as to the
amount of any such adjustment, if required, shall be binding upon the holders
of the Warrants and the Company if made in good faith by the Board of Directors
of the Company.


         SECTION 11.      Fractional Warrants and Fractional Shares.  The
Company shall not be required to issue fractions of shares, upon exercise of
the Warrants or otherwise, or to distribute certificates that evidence
fractional shares.  With respect to any fraction of a share called for upon any
exercise hereof, the Company shall round such fraction downward to the nearest
whole share, without the payment of any further consideration.


         SECTION 12.      Warrantholders Not Deemed Stockholders.  No holder of
Warrants shall, as such, be entitled to vote or to receive dividends or be
deemed the holder of Common Stock that may at any time be issuable upon
exercise of such Warrants for any purpose whatsoever, nor shall anything
contained herein be construed to confer upon the holder of Warrants, as such,
any of the rights of a stockholder of the Company or any right to vote for the
election of directors or upon any matter submitted to stockholders at any
meeting thereof, or to give or withhold consent to any corporate action
(whether upon any recapitalization, issue or reclassification of stock, change
of par value or change of stock to no par value, consolidation, merger or
conveyance or otherwise), or to receive notice of meetings, or to receive
dividends or subscription rights, until such holder shall have exercised such
Warrants and been issued shares of Common Stock in accordance with the
provisions hereof.


         SECTION 13.      Rights of Action.  All rights of action with respect
to this Agreement are vested in the respective Registered Holders of the
Warrants, and any Registered Holder of a Warrant, without consent of the
Warrant Agent or of the holder of any other Warrant, may, in his own behalf and
for his own benefit, enforce against the Company his right to exercise his
Warrants for the purchase of shares of Common Stock in the manner provided in
the Warrant Certificates and this Agreement.


         SECTION 14.      Agreement of Warrantholders.  Every holder of a
Warrant, by his acceptance thereof, consents and agrees with the Company, the
Warrant Agent and every other holder of a Warrant that:

         (a)     The Warrants are transferable only on the registry books of
the Warrant Agent by the Registered Holder thereof in person or by his attorney
duly authorized in writing and only if the Warrant Certificates representing
such Warrants are surrendered at the office of the Warrant Agent, duly endorsed
or accompanied by a proper instrument of transfer satisfactory to the Warrant
Agent and the Company in their sole discretion, together with payment of any
applicable transfer taxes; and





                                       16
<PAGE>   17
         (b)     The Company and the Warrant Agent may deem and treat the
person in whose name the Warrant Certificate is registered as the holder and as
the absolute, true and lawful owner of the Warrants represented thereby for all
purposes, and neither the Company nor the Warrant Agent shall be affected by
any notice or knowledge to the contrary, except as otherwise expressly provided
in Section 7 hereof.


         SECTION 15.      Cancellation of Warrant Certificates.  If the company
shall purchase or acquire any Warrant or Warrants, the Warrant Certificate or
Warrant Certificates evidencing the same shall thereupon be delivered to the
Warrant Agent and canceled by it and retired.  The Warrant Agent shall also
cancel Common Stock following exercise of any or all of the Warrants
represented thereby or delivered to it for transfer, split-up, combination or
exchange.


         SECTION 16.      Concerning the Warrant Agent.  The Warrant Agent acts
hereunder as agent and in a ministerial capacity for the Company, and its
duties shall be determined solely by the provisions hereof.  The Warrant Agent
shall not, by issuing and delivering Warrant Certificates or by any other act
hereunder be deemed to make many representations as to the validity, value or
authorization of the Warrant Certificates or the Warrants represented thereby
or of any securities or other property delivered upon exercise of any Warrant
or whether any stock issued upon exercise of any Warrant is fully paid and
nonassessable.

         The Warrant Agent shall not at any time be under any duty or
responsibility to any holder of Warrant Certificates to make or cause to be
made any adjustment of the Purchase Price or the Redemption Price provided in
this Agreement, or to determine whether any fact exists which may require any
such adjustments, or with respect to the nature or extent of any such
adjustment, when made, or with respect to the method employed in making the
same.  It shall not (i) be liable for any recital or statement of facts
contained herein or for any action taken, suffered or omitted by it in reliance
on any Warrant Certificates or other document of instrument believed by it in
good faith to be genuine and to have been signed or presented by the proper
party or parties, (ii) be responsible for any failure on the part of the
Company to comply with any of its covenants and obligations contained in this
Agreement or in any Warrant Certificate, or (iii) be liable for any act or
omission in connection with this Agreement except for its own negligence or
willful misconduct.

         The Warrant Agent may at any time consult with counsel satisfactory to
it (who may be counsel for the Company) and shall incur no liability or
responsibility for any action taken, suffered or omitted by it in good faith in
accordance with the opinion or advice of such counsel.

         Any notice, statement, instruction, request, direction, order or
demand of the Company shall be sufficiently evidenced by an instrument signed
by the Chairman of the Board, President, any Vice President, its Secretary, or
Assistant Secretary, (unless other evidence in respect thereof is herein
specifically prescribed).  The Warrant Agent shall not be liable for any action
taken, suffered or omitted by it in accordance with such notice, statement,
instruction, request, direction, order or demand believed by it to be genuine.





                                       17
<PAGE>   18
         The Company agrees to pay the Warrant Agent reasonable compensation
for its services hereunder and to reimburse it for its reasonable expenses
hereunder; it further agrees to indemnify the Warrant Agent and save it
harmless against any and all losses, expenses and liabilities, including
judgments, costs and counsel fees, for anything done or omitted by the Warrant
Agent in the execution of its duties and powers hereunder except losses,
expenses and liabilities arising as a result of the Warrant Agent's negligence
or willful misconduct.

         The Warrant Agent may resign its duties and be discharged from all
further duties and liabilities hereunder (except liabilities arising as a
result of the Warrant Agent's own negligence or wilful misconduct), after
giving 30 days' prior written notice to the Company.  At least 15 days prior to
the date such resignation is to become effective, the Warrant Agent shall cause
a copy of such notice of resignation to be mailed to the Registered Holder of
each Warrant Certificate at the Company's expense.  Upon such resignation, or
any inability of the Warrant Agent to act as such hereunder, the Company shall
appoint a new warrant agent in writing.  If the Company shall fail to make such
appointment within a period of 15 days after it has been notified in writing of
such resignation by the resigning Warrant Agent, then the Registered Holder of
any Warrant Certificate may apply to any court of competent jurisdiction for
the appointment of a new warrant agent.  Any new warrant agent, whether
appointed by the Company or by such a court shall be a bank or trust company
having a capital and surplus as shown by its last published report to its
stockholders, of not less than $10,000,000, or a stock transfer company.  After
acceptance in writing of such appointment by the new warrant agent is received
by the Company, such new warrant agent shall be vested with the same powers,
rights, duties and responsibilities as if it had been originally named herein
as the Warrant Agent, without any further assurance, conveyance, act or deed;
but if for any reason it shall be necessary or expedient to execute and deliver
any further assurance, conveyance, act or deed, the same shall be done at the
expense of the Company and shall be legally and validly executed and delivered
by the resigning Warrant Agent.  Not later than the effective date of any such
appointment the Company shall file notice thereof with the resigning Warrant
Agent and shall forthwith cause a copy of such notice to be mailed to the
Registered Holder of each Warrant Certificate.

         Any corporation into which the Warrant Agent or any new warrant agent
may be converted or merged or any corporation resulting from any consolidation
to which the Warrant Agent or any new warrant agent shall be a party or any
corporation succeeding to the trust business of the Warrant Agent shall be a
successor warrant agent under this Agreement without any further act, provided
that such corporation is eligible for appointment as successor to the Warrant
Agent under the provisions of the preceding paragraph.  Any such successor
warrant agent shall promptly cause notice of its succession as warrant agent to
be mailed to the Company and to the Registered Holder of each Warrant
Certificate.

         The Warrant Agent, its subsidiaries and affiliates, and any of its or
their officers or directors, may buy and hold or sell Warrants or other
securities of the Company and otherwise deal with the Company in the same
manner and to the same extent and with like effects as though it were not
Warrant Agent.  Nothing herein shall preclude the Warrant Agent from acting in
any other capacity for the Company or for any other legal entity.

         SECTION 17.      Modification of Agreement.  The Warrant Agent and the
Company may by supplemental agreement make any changes or corrections in this
Agreement (i) that they shall deem appropriate to cure any ambiguity or to
correct any defective or inconsistent provision or manifest mistake or error
herein contained; or (ii) that they may deem necessary or desirable and which
shall not adversely affect the interests of the holders of Warrant
Certificates; provided, however, that this Agreement shall not otherwise be
modified, supplemented or altered in any respect except with the consent in
writing of the Registered Holders of Warrant Certificates representing not less
than 50% of the Warrants then outstanding, and provided, further, that no
change in the number or nature of the securities purchasable upon the exercise
of any Warrant, or the Purchase Price therefor, or the acceleration of the
Warrant Expiration Date, shall be made without the consent in writing of the
Registered Holder of the Warrant Certificate representing such Warrant, other
than such changes as are specifically prescribed by this Agreement as
originally executed.

         Notwithstanding the preceding or anything else in this Agreement to
the contrary, the Warrant Agent and the Company may by amendment or
supplemental agreement from time to time modify the Purchase Price without the
obtaining the consent of any of the Registered Holders of the Warrants.


         SECTION 18.      Notices.  All notices, requests, consents and other
communications hereunder shall be in writing and shall be deemed to have been
made when delivered or mailed first class registered or certified mail, postage
prepaid as follows: if to the Registered Holder of a Warrant Certificate, at
the address of such holder as shown on the registry books maintained by the
Warrant Agent; if to the Company, at 8200 Springwood Drive, Suite 230, Irving,
Texas 75063, attention: President, or at such other address as may have been
furnished to the Warrant Agent in writing by the Company; and if to the Warrant
Agent, at 40 Wall Street, New York, New York 10005.


         SECTION 19.      Governing Law.  This Agreement shall be governed by
and construed in accordance with the laws of the State of Delaware, without
reference to principles of conflict of laws.


         SECTION 20.      Binding Effect.  This Agreement shall be binding upon
and inure to the benefit of the Company and, the Warrant Agent and their
respective successors and assigns, and the holders from time to time of Warrant
Certificates.  Nothing in this Agreement is intended or shall be construed to
confer upon any other person any right, remedy or claim, in equity or at law,
or to impose upon any other person any duty, liability or obligation.

         SECTION 21.      Termination.  This Agreement shall terminate at the
close of business on the Expiration Date of all the Warrants of such earlier
date upon which all Warrants have been exercised, except that the Warrant Agent
shall account to the Company for cash held by it and the provisions of Section
16 hereof shall survive such termination.

         SECTION 22.      Counterparts.  This Agreement may be executed in
several counterparts, which taken together shall constitute a single document.

                     [FORM OF FACE OF WARRANT CERTIFICATE]

                                                       Warrants
                                                       VOID AFTER April 20, 1999


                        WARRANT CERTIFICATE FOR PURCHASE
                                       OF
                                  COMMON STOCK
                                       OF
                       INTEGRATED SECURITY SYSTEMS, INC.


         This certifies that FOR VALUE RECEIVED ____________________________ or
registered assigns (the "Registered Holder") is the owner of the number of
Common Stock Purchase Warrants (the "Warrants") specified above.  Each Warrant
initially entitles the Registered Holder to purchase, subject to the terms and
conditions set forth in this Certificate and the Warrant Agreement (as
hereinafter defined), 2.1 fully paid and nonassessable shares of Common Stock,
$.01 par value, of Integrated Security Systems, Inc., a Delaware corporation
(the "Company") at any time prior to or on the Expiration Date (as hereinafter
defined), upon the presentation and surrender of this Warrant Certificate with
the Subscription Form on the reverse hereof duly executed, at the corporate
office of American Stock Transfer & Trust Company as Warrant Agent, or its
successor (the "Warrant Agent"), accompanied by payment of $3.17 per share (the
"Purchase Price") in lawful money of the United States of America in cash or by
official bank or certified check made payable to the Company.

         This Warrant Certificate and each Warrant represented hereby are
issued pursuant to and are subject in all respects to the terms and conditions
set forth in the Warrant Agreement (the "Warrant Agreement"), dated as of
February 26, 1998, by and between the Company and the Warrant Agent.

         In the event of certain contingencies provided for in the Warrant
Agreement, the Purchase Price or the number of shares of Common Stock subject
to purchase upon the exercise of each Warrant represented hereby are subject to
modification or adjustment.

         Each Warrant represented hereby is exercisable at the option of the
Registered Holder, but no fractional shares of Common Stock will be issued.  In
the case of the exercise of less than all the Warrants represented hereby, the
Company shall cancel this Warrant Certificate upon the surrender hereof and
shall execute and deliver a new Warrant Certificate or Warrant Certificates of
like tenor, which the Warrant Agent shall countersign, for the balance of such
Warrants.





                                       22
<PAGE>   23
         The term "Expiration Date" shall mean 5:00 p.m. (New York City time)
on April 20, 1999, or such earlier date as the Warrants shall be redeemed.  If
such date shall in the State of New York be a holiday or a day on which the
banks are authorized to close, then the Expiration Date shall be 5:00 p.m. (New
York City time) the next following day which in the State of New York is not a
holiday or a day in which banks are authorized to close.  The Company shall not
be obligated to deliver any securities pursuant to the exercise of this Warrant
unless a registration statement under the Securities Act of 1933, as amended,
with respect to such securities is effective.  The Company has covenanted and
agreed that it will file a registration statement and will use its best efforts
to cause the same to become effective and to keep such registration statement
current while any of the Warrants are outstanding.  This Warrant shall not be
exercisable by a Registered Holder in any state where such exercise would be
unlawful.

         This Warrant Certificate is exchangeable, upon the surrender hereof by
the Registered Holder at the corporate office of the Warrant Agent, for a new
Warrant Certificate or Warrant Certificates of like tenor representing an equal
aggregate number of Warrants, each of such new Warrant Certificates to
represent such number of Warrants as shall be designated by such Registered
Holder at the time of such surrender.  Upon due presentment together with any
tax or other governmental charge imposed in connection therewith, for
registration of transfer of this Warrant Certificate at such office, a new
Warrant Certificate or Warrant Certificates representing an equal aggregate
number of Warrants will be issued to the transferee in exchange therefor,
subject to the limitations provided in the Warrant Agreement.

         Prior to the exercise of any warrant represented hereby, the
Registered Holder shall not be entitled to any rights of a stockholder of the
Company, including, without limitation, the right to vote or to receive
dividends or other distributions, and shall not be entitled to receive any
notice of any proceedings of the Company, except as provided in the Warrant
Agreement.

         Commencing 90 days after the date of the Warrant Agreement, this
Warrant may be redeemed at the option of the Company at redemption price of
$.25 per Warrant.  Notice of redemption shall be given not later than the
thirtieth day before the date fixed for redemption, all as provided in the
Warrant Agreement.  On and after the date fixed for redemption, the Registered
Holder shall have no rights with respect to this Warrant except to receive the
$.25 per Warrant upon surrender of this Certificate.

         Prior to due presentment for registration of transfer hereof, the
Company and the Warrant Agent may deem and treat the Registered Holder as the
absolute owner hereof and of each Warrant represented hereby (notwithstanding
any notations of ownership or writing hereon made by anyone other than a duly
authorized officer of the Company or the Warrant Agent) for all purposes and
shall not be affected by any notice to the contrary.

         This Warrant Certificate shall be governed by and construed in
accordance with the laws of the State of Delaware.

         This Warrant Certificate is not valid unless countersigned by the
Warrant Agent.
