     2.   EXERCISE OF WARRANT.

          This Warrant may be exercised by the Warrant Holder, in whole or in 
part, at any time and from time to time by either of the following methods:

          (a)  The Warrant Holder may surrender this Warrant, together with 
the form of subscription at the end hereof duly executed by Warrant Holder 
("SUBSCRIPTION NOTICE"), at the offices of the Company or any transfer agent 
for the Common Stock; or

          (b)  The Warrant Holder may also exercise this Warrant, in whole or 
in part, in a "cashless" or "net-issue" exercise by delivering to the offices 
of the Company or any transfer agent for the Common Stock this Warrant, 
together with a Subscription Notice specifying the number of Warrant Shares 
to be delivered to such Warrant Holder ("DELIVERABLE SHARES") and the number 
of Warrant Shares with respect to which this Warrant is being surrendered in 
payment of the aggregate Purchase Price for the Deliverable Shares 
("SURRENDERED SHARES"); provided that the Purchase Price multiplied by the 
number of Deliverable Shares shall not exceed the value of the Surrendered 
Shares; and provided further that the sum of the number of Deliverable Shares 
and the number of Surrendered Shares so specified shall not exceed the 
aggregate number of Warrant Shares represented by this Warrant.  For the 
purposes of this provision, each Warrant Share as to which this Warrant is 
surrendered will be attributed a value equal to the fair market value (as 
defined below) of the Warrant Share minus the Purchase Price of the Warrant 
Share.

                                     2


     In the event that the Warrant is not exercised in full, the number of 
Warrant Shares shall be reduced by the number of such Warrant Shares for 
which this Warrant is exercised and/or surrendered, and the Company, at its 
expense, shall within three (3) Trading Days (as defined below) issue and 
deliver or upon the order of Warrant Holder a new Warrant of like tenor in 
the name of Warrant Holder or as Warrant Holder (upon payment by Warrant 
Holder of any applicable transfer taxes) may request, reflecting such 
adjusted Warrant Shares.

     3.   DELIVERY OF STOCK CERTIFICATES.

          (a)  Subject to the terms and conditions of this Warrant, as soon 
as practicable after the exercise of this Warrant in full or in part, and in 
any event within three (3) Trading Days thereafter, the Company shall 
transmit the certificates (together with any other stock or other securities 
or property to which Warrant Holder is entitled upon exercise) by messenger 
or overnight delivery service to reach the address designated by such holder 
within three (3) Trading Days after the receipt of the Subscription Notice 
("T+3").  If such certificates are not received by the Warrant Holder within 
T+3, then the Warrant Holder will be entitled to revoke and withdraw its 
exercise of its Warrant at any time prior to its receipt of those 
certificates.

     In lieu of delivering physical certificates representing the Warrant 
Shares deliverable upon exercise of Warrants, provided the Company's transfer 
agent is participating in the Depository Trust Company ("DTC") Fast Automated 
Securities Transfer ("FAST") program, upon request of the Warrant Holder, the 
Company shall use its best efforts to cause its transfer agent to 
electronically transmit the Warrant Shares issuable upon exercise to the 
Warrant Holder, by crediting the account of Warrant Holder's prime broker 
with DTC through its Deposit Withdrawal Agent Commission ("DWAC") system.  
The time periods for delivery described above shall apply to the electronic 
transmittals through the DWAC system.  The parties agree to coordinate with 
DTC to accomplish this objective.  The exchange pursuant to Section 3 shall 
be deemed to have been made immediately prior to the close of business on the 
date of the Subscription Notice.  The person or persons entitled to receive 
the Warrant Shares issuable upon such exercise shall be treated for all 
purposes as the record holder or holders of such Common Shares at the close 
of business on the date of the Subscription Notice.

     The term Trading Day means (x) if the Common Stock is listed on the New 
York Stock Exchange or the American Stock Exchange, a day on which there is 
trading on such stock exchange, (y) if the Common Stock is not listed on 
either of such stock exchanges but sale prices of the Common Stock are 
reported on an automated quotation system, a day on which trading is reported 
on the principal automated quotation system on which sales of the Common 
Stock are reported, or (z) if the foregoing provisions are inapplicable, a 
day on which quotations are reported by National Quotation Bureau 
Incorporated.

          (b)  This Warrant may not be exercised as to fractional shares of 
Common Stock.  In the event that the exercise of this Warrant, in full or in 
part, would result in the issuance of any fractional share of Common Stock, 
then in such event the Warrant Holder shall be entitled to cash equal to the 
fair market value of such fractional share.  For purposes of this Warrant, 
"fair market value" shall equal the Closing Bid Price on the Approved Market 
which is the principal trading exchange or market for the Common Stock (the 
"Principal Market") on the date of determination or, if the Common Stock is 
not listed or admitted to trading on any 

                                     3


Approved Market, the average of the closing bid and asked prices on the 
over-the-counter market as furnished by any New York Stock Exchange member 
firm reasonably selected from time to time by the Company for that purpose 
and reasonably acceptable to the Warrant Holder, or, if the Common Stock is 
not listed or admitted to trading on any Approved Market or traded 
over-the-counter and the average price cannot be determined a contemplated 
above, the fair market value of the Common Stock shall be as reasonably 
determined in good faith by the Company's Board of Directors with the 
concurrence of the Warrant Holder.

     4.   (A)  REPRESENTATIONS AND COVENANTS OF THE COMPANY.

          (a)  The Company shall comply with its obligations under the 
Registration Rights Agreement with respect to the Warrant Shares, including, 
without limitation, the Company's obligation to have filed and declared and 
maintained effective a registration statement registering the Warrant Shares 
under the Securities Act of 1933, as amended (the "ACT").

          (b)  The Company shall take all necessary action and proceedings as 
may be required and permitted by applicable law, rule and regulation, 
including, without limitation, the notification of the Principal Market, for 
the legal and valid issuance of this Warrant and the Warrant Shares to the 
Warrant Holder under this Warrant.

          (c)  From the date hereof through the last date on which this 
Warrant is exercisable, the Company shall take all steps necessary to insure 
that the Common Stock remains listed on the Principal Market.

          (d)  The Warrant Shares, when issued in accordance with the terms 
hereof, will be duly authorized and, when paid for or issued in accordance 
with the terms hereof, shall be validly issued, fully paid and 
non-assessable.  The Company has authorized and reserved for issuance to 
Warrant Holder the requisite number of shares of Common Stock to be issued 
pursuant to this Warrant.

          (e)  The Company shall at all times reserve and keep available, 
solely for issuance and delivery as Warrant Shares hereunder the number of 
shares specified in Section 3.10 of the Purchase Agreement.

          (f)  With a view to making available to the Warrant Holder the 
benefits of Rule 144 promulgated under the Act and any other rule or 
regulation of the Securities and Exchange Commission ("SEC") that may at any 
time permit Warrant Holder to sell securities of the Company to the public 
without registration, the Company agrees to use its best efforts to:

               (i)   make and keep public information available, as those 
terms are understood and defined in Rule 144, at all times;

               (ii)  file with the SEC in a timely manner all reports and 
other documents required of the Company under the Act and the Securities 
Exchange Act of 1934, as amended (the "Exchange Act"); and

                                     4


               (iii) furnish to any Warrant Holder forthwith upon request a 
written statement by the Company that it has complied with the reporting 
requirements of Rule 144 and of the Act and the Exchange Act, a copy of the 
most recent annual or quarterly report of the Company, and such other reports 
and documents so filed by the Company as may be reasonably requested to 
permit any such Warrant Holder to take advantage of any rule or regulation of 
the SEC permitting the selling of any such securities without registration.

          (B)  REPRESENTATIONS AND COVENANTS OF THE PURCHASER.

               The Purchaser shall not resell this Warrant or the Warrant 
Shares, unless such resale is pursuant to an effective registration statement 
under the Act or pursuant to an applicable exemption from such registration 
requirements.

     5.   ADJUSTMENT OF PURCHASE PRICE AND NUMBER OF SHARES.  The number of 
and kind of securities purchasable upon exercise of this Warrant and the 
Purchase Price shall be subject to adjustment from time to time as follows:

          (a)  SUBDIVISIONS, COMBINATIONS AND OTHER ISSUANCES.  If the 
Company shall at any time after the date hereof but prior to the expiration 
of this Warrant subdivide its outstanding securities as to which purchase 
rights under this Warrant exist, by split-up, spin-off, or otherwise, or 
combine its outstanding securities as to which purchase rights under this 
Warrant exist, the number of Warrant Shares as to which this Warrant is 
exercisable as of the date of such subdivision, split-up, spin-off or 
combination shall forthwith be proportionately increased in the case of a 
subdivision, or proportionately decreased in the case of a combination. 
Appropriate proportional adjustments (decrease in the case of subdivision, 
increase in the case of combination) shall also be made to the Purchase Price 
payable per share, so that the aggregate Purchase Price payable for the total 
number of Warrant Shares purchasable under this Warrant as of such date shall 
remain the same as it would have been before such subdivision or combination.

          (b)  STOCK DIVIDEND.  If at any time after the date hereof the 
Company declares a dividend or other distribution on Common Stock payable in 
Common Stock or other securities or rights convertible into or exchangeable 
for Common Stock ("COMMON STOCK EQUIVALENTS") without payment of any 
consideration by holders of Common Stock for the additional shares of Common 
Stock or the Common Stock Equivalents (including the additional shares of 
Common Stock issuable upon exercise or conversion thereof), then the number 
of shares of Common Stock for which this Warrant may be exercised shall be 
increased as of the record date (or the date of such dividend distribution if 
no record date is set) for determining which holders of Common Stock shall be 
entitled to receive such dividends, in proportion to the increase in the 
number of outstanding shares (and shares of Common Stock issuable upon 
conversion of all such securities convertible into Common Stock) of Common 
Stock as a result of such dividend, and the Purchase Price shall be 
proportionately reduced so that the aggregate Purchase Price for all the 
Warrant Shares issuable hereunder immediately after the record date (or on 
the date of such distribution, if applicable), for such dividend shall equal 
the aggregate Purchase Price so payable immediately before such record date 
(or on the date of such distribution, if applicable).

                                     5


          (c)  OTHER DISTRIBUTIONS.  If at any time after the date hereof the 
Company distributes to holders of its Common Stock, other than as part of its 
dissolution, liquidation or the winding up of its affairs, any shares of its 
capital stock, any evidence of indebtedness or any of its assets (other than 
Common Stock), then the number of Warrant Shares for which this Warrant is 
exercisable shall be increased to equal: (i) the number of Warrant Shares for 
which this Warrant is exercisable immediately prior to such event, (ii) 
multiplied by a fraction, (A) the numerator of which shall be the fair market 
value per share of Common Stock on the record date for the dividend or 
distribution, and (B) the denominator of which shall be the fair market value 
per share of Common Stock on the record date for the dividend or distribution 
minus the amount allocable to one share of Common Stock of the value (as 
determined in good faith by the Board of Directors of the Company) of any and 
all such evidences of indebtedness, shares of capital stock, other securities 
or property, so distributed.  If the value of the distribution exceeds 10% of 
the value of the outstanding Common Stock, at the request of Warrant Holders 
holding an aggregate of at least 50,000 Warrants, the valuation described in 
the preceding sentence shall be determined, at the Company's expense, by a 
nationally recognized investment banking firm or other nationally recognized 
financial advisor retained by the Company with the approval of the Warrant 
Holder.  The Purchase Price shall be reduced to equal: (i) the Purchase Price 
in effect immediately before the occurrence of any event (ii) multiplied by a 
fraction, (A) the numerator of which is the number of Warrant Shares for 
which this Warrant is exercisable immediately before the adjustment, and (B) 
the denominator of which is the number of Warrant Shares for which this 
Warrant is exercisable immediately after the adjustment.

          (d)  MERGER, ETC.  If at any time after the date hereof there shall 
be a merger or consolidation of the Company with or into or a transfer of all 
or substantially all of the assets of the Company to another entity, then the 
Warrant Holder shall be entitled to receive upon or after such transfer, 
merger or consolidation becoming effective, and upon payment of the Purchase 
Price then in effect, the number of shares or other securities or property of 
the Company or of the successor corporation resulting from such merger or 
consolidation, which would have been received by Warrant Holder for the 
shares of stock subject to this Warrant had this Warrant been exercised just 
prior to such transfer, merger or consolidation becoming effective or to the 
applicable record date thereof, as the case may be.  The Company will not 
merge or consolidate with or into any other corporation, or sell or otherwise 
transfer its property, assets and business substantially as an entirety to 
another corporation, unless the corporation resulting from such merger or 
consolidation (if not the Company), or such transferee corporation, as the 
case may be, shall expressly assume, by supplemental agreement, the due and 
punctual performance and observance of each and every covenant and condition 
of this Warrant to be performed and observed by the Company, as adjusted to 
preserve the economic benefits receivable by the Warrant Holder upon exercise.

          (e)  In addition to the foregoing, if the holders of shares of 
Common Stock receive any non-publicly traded securities or other property or 
cash as part or all of the consideration for such reorganization, 
consolidation, merger or sale, then such distribution shall be treated to the 
extent thereof as a distribution under Section 7(a) above and such Section 
shall also apply to such distribution.  To the extent that, pursuant to the 
foregoing adjustments, (i) the Warrants become exercisable into securities of 
an issuer with a greater number of outstanding shares of common stock than 
the Company and (ii) on the date of the relevant merger agreement or the date 
on which the terms of the restructuring are set, the fair market value of a 
share of 

                                     6


Common Stock is less than the Purchase Price, then the adjustments set forth 
in Section 5(f) herein shall also be applied as if the additional shares were 
issued after the effective date of the merger or reorganization.

          (f)  RECLASSIFICATION, ETC.  If at any time after the date hereof 
there shall be a reorganization or reclassification of the securities as to 
which purchase rights under this Warrant exist into the same or a different 
number of securities of any other class or classes, then the Warrant Holder 
shall thereafter be entitled to receive upon exercise of this Warrant, during 
the period specified herein and upon payment of the Purchase Price then in 
effect, the number of shares or other securities or property resulting from 
such reorganization or reclassification, which would have been received by 
the Warrant Holder for the shares of stock subject to this Warrant had this 
Warrant at such time been exercised.

          (g)  PURCHASE PRICE ADJUSTMENT.  In the event that within twelve 
(12) months of the Closing Date the Company issues or sells any Common Stock 
or securities which are convertible into or exchangeable for its Common Stock 
or any convertible securities, or any warrants or other rights to subscribe 
for or to purchase or any options for the purchase of its Common Stock or any 
such convertible securities (other than shares or options issued or which may 
be issued pursuant to the Company's current employee or director option plans 
or stock purchase plans, as amended consistent with the practice in the 
high-technology sector, at prices consistent with past practice, or shares 
issued upon exercise of options, warrants or rights outstanding on the date 
of the Agreement and listed in Section 2(c) of the Company's Disclosure 
Schedule or shares issued in a Matridigm Transaction) at an effective 
purchase price per share which is less than the greater of the Purchase Price 
then in effect or the fair market value (as defined in Section 3(b) above) of 
the Common Stock on the trading day next preceding such issue or sale, then 
in each such case, the Purchase Price in effect immediately prior to such 
issue or sale shall be reduced effective concurrently with such issue or sale 
to an amount determined by multiplying the Purchase Price then in effect by a 
fraction, (x) the numerator of which shall be the sum of (1) the number of 
shares of Common Stock outstanding immediately prior to such issue or sale, 
plus (2) the number of shares of Common Stock which the aggregate 
consideration received by the Company for such additional shares would 
purchase at such fair market value or, Purchase Price as the case may be, 
then in effect; and (y) the denominator of which shall be the number of 
shares of Common Stock of the Company outstanding immediately after such 
issue or sale.

     For the purposes of the foregoing adjustment, in the case of the 
issuance of any convertible securities, warrants, options or other rights to 
subscribe for or to purchase or exchange for, shares of Common Stock 
("CONVERTIBLE SECURITIES"), the maximum number of shares of Common Stock 
issuable upon exercise, exchange or conversion of such Convertible Securities 
shall be deemed to be outstanding, provided that no further adjustment shall 
be made upon the actual issuance of Common Stock upon exercise, exchange or 
conversion of such Convertible Securities.

     The number of shares which may be purchased hereunder shall be increased 
proportionately to any reduction in Purchase Price pursuant to this paragraph 
5(f), so that after such adjustments the aggregate Purchase Price payable 
hereunder for the increased number of shares shall be the same as the 
aggregate Purchase Price in effect just prior to such adjustments.

                                     7


     In the event of any such issuance for a consideration which is less than 
such fair market value and also less than the Purchase Price then in effect, 
than there shall be only one such adjustment by reason of such issuance, such 
adjustment to be that which results in the greatest reduction of the Purchase 
Price computed as aforesaid.

     6.   NO IMPAIRMENT.  The Company will not, by amendment of its 
Certificate of Incorporation or through any reorganization, transfer of 
assets, consolidation, merger, dissolution, issue or sale of securities or 
any other voluntary action, avoid or seek to avoid the observance or 
performance of any of the terms of this Warrant, but will at all times in 
good faith assist in the carrying out of all such terms and in the taking of 
all such action as may be necessary or appropriate in order to protect the 
rights of the Warrant Holder against impairment.  Without limiting the 
generality of the foregoing, the Company (a) will not increase the par value 
of any Warrant Shares above the amount payable therefor on such exercise, and 
(b) will take all such action as may be reasonably necessary or appropriate 
in order that the Company may validly and legally issue fully paid and 
nonassessable Warrant Shares on the exercise of this Warrant.

     7.   NOTICE OF ADJUSTMENTS.  Whenever the Purchase Price or number of 
Shares purchasable hereunder shall be adjusted pursuant to Section 5 hereof, 
the Company shall execute and deliver to the Warrant Holder a certificate 
setting forth, in reasonable detail, the event requiring the adjustment, the 
amount of the adjustment, the method by which such adjustment was calculated 
and the Purchase Price and number of shares purchasable hereunder after 
giving effect to such adjustment, and shall cause a copy of such certificate 
to be mailed (by first class mail, postage prepaid) to the Warrant Holder.

     8.   RIGHTS AS STOCKHOLDER.  Prior to exercise of this Warrant, the 
Warrant Holder shall not be entitled to any rights as a stockholder of the 
Company with respect to the Warrant Shares, including (without limitation) 
the right to vote such shares, receive dividends or other distributions 
thereon or be notified of stockholder meetings.  However, in the event of any 
taking by the Company of a record of the holders of any class of securities 
for the purpose of determining the holders thereof who are entitled to 
receive any dividend (other than a cash dividend) or other distribution, any 
right to subscribe for, purchase or otherwise acquire any shares of stock of 
any class or any other securities or property, or to receive any other right, 
the Company shall mail to each Warrant Holder, at least 10 Trading Days prior 
to the date specified therein, a notice specifying the date on which any such 
record is to be taken for the purpose of such dividend, distribution or 
right, and the amount and character of such dividend, distribution or right.

     9.   LIMITATION ON EXERCISE.  Notwithstanding anything to the contrary 
contained herein, this Warrant may not be exercised by the Warrant Holder to 
the extent that, after giving effect to Warrant Shares to be issued pursuant 
to a Subscription Notice, the total number of shares of Common Stock deemed 
beneficially owned by such holder (other than by virtue of ownership of this 
Warrant, or ownership of other securities that have limitations on the 
holder's rights to convert or exercise similar to the limitations set forth 
herein), together with all shares of Common Stock deemed beneficially owned 
by the holder's "affiliates" (as defined in Rule 144 of the Act) that would 
be aggregated for purposes of determining whether a group under Section 13(d) 
of the Securities Exchange Act of 1934, as amended (the "EXCHANGE ACT") 
exists, would 

                                     8


exceed the Warrant Holder's Restricted Ownership Percentage specified on 
Schedule I to the Agreement; provided that (w) each Warrant Holder shall have 
the right at any time and from time to time to reduce its Restricted 
Ownership Percentage immediately upon notice to the Company or in the event 
of a Change in Control Transaction, (x) each Warrant Holder shall have the 
right at any time and from time to time to increase its Restricted Ownership 
Percentage or otherwise waive in whole or in part the restrictions of this 
Section 9 upon 61 days' prior notice to the Company or immediately in the 
event of a Change in Control Transaction, (y) each Warrant Holder can make 
subsequent adjustments pursuant to (w) or (x) any number of times from time 
to time (which adjustment shall be effective immediately if it results in a 
decrease in the Restricted Ownership Percentage or shall be effective upon 61 
days' prior written notice or immediately in the event of a Change in Control 
Transaction if it results in an increase in the Restricted Ownership 
Percentage) and (z) each Warrant Holder may eliminate or reinstate this 
limitation at any time and from time to time (which elimination will be 
effective upon 61 days' prior notice and which reinstatement will be 
effective immediately).  Without limiting the foregoing, in the event of a 
Change in Control Transaction, any holder may reinstate immediately (in whole 
or in part) the requirement that any increase in its Restricted Ownership 
Percentage be subject to 61 days' prior written notice, notwithstanding such 
Change in Control Transaction, without imposing such requirement on, or 
otherwise changing such holder's rights with respect to, any other Change in 
Control Transaction.  For this purpose, any material modification of the 
terms of a Change in Control Transaction will be deemed to create a new 
Change in Control Transaction.  The term "DEEMED BENEFICIALLY OWNED" as used 
in this Warrant shall exclude shares that might otherwise be deemed 
beneficially owned by reason of the convertibility of the Preferred Shares.  
A "CHANGE IN CONTROL TRANSACTION" will be deemed to have occurred upon the 
earlier of the announcement or consummation of a transaction or series of 
transactions (other than the Merger) involving (x) any consolidation or 
merger of the Company with or into any other corporation or other entity or 
person (whether or not the Company is the surviving corporation), or any 
other corporate reorganization or transaction or series of related 
transactions in which in excess of 50% of the Company's voting power is 
transferred through a merger, consolidation, tender offer or similar 
transaction, or (y) in excess of 50% of the Company's Board of Directors 
consists of directors not nominated by the prior Board of Directors of the 
Company, or (z) any person (as defined in Section 13(d) of the Exchange Act, 
together with its affiliates and associates (as such terms are defined in 
Rule 405 under the Act), beneficially owns or is deemed to beneficially own 
(as described in Rule 13d-3 under the Exchange Act without regard to the 
60-day exercise period) in excess of 50% of the Company's voting power.  The 
delivery of a Subscription Notice by the Warrant Holder shall be deemed a 
representation by such holder that it is in compliance with this paragraph.

     10.  REPLACEMENT OF WARRANT.  On receipt of evidence reasonably 
satisfactory to the Company of the loss, theft, destruction or mutilation of 
this Warrant and, in the case of any such loss, theft or destruction of this
