         2. METHOD OF EXERCISE PAYMENT; ISSUANCE OF NEW WARRANT; TRANSFER AND
EXCHANGE.

         (a) TIME OF EXERCISE. The purchase rights represented by this Warrant
may be exercised in whole or in part at any time and from time to time during
the Term.

         (b) METHOD OF EXERCISE. The Holder hereof may exercise this Warrant, in
whole or in part, by the surrender of this Warrant (with the exercise form
attached hereto duly executed) at the principal office of the Issuer, together
with the payment to the Issuer of an amount of consideration therefor equal to
the Warrant Price in effect on the date of such exercise multiplied by the
number of shares of Warrant Stock with respect to which this Warrant is then
being exercised, payable at such Holder's election (i) by certified or official
bank check or by wire transfer to an account designated by the Issuer, (ii)
commencing one (1) year after the Original Issue Date, by "cashless exercise" by
surrender to the Issuer for cancellation of a portion of this Warrant
representing that number of unissued shares of Warrant Stock which is equal to
the quotient obtained by dividing (A) the product obtained by multiplying the
Warrant Price by the number of shares of Warrant Stock being purchased upon such
exercise by (B) the Per Share Market Value as of the date of such exercise, or
(iii) commencing one (1) year after the Original Issue Date, by a combination of
the foregoing methods of payment selected by the Holder of this Warrant. In any
case where the consideration payable upon such exercise is being paid in whole
or in part pursuant to the provisions of clause (ii) of this subsection (b),
such exercise shall be accompanied by written notice from the Holder of this
Warrant specifying the manner of payment thereof and containing a calculation
showing the number of shares of Warrant Stock with respect to which rights are
being surrendered thereunder and the net number of shares to be issued after
giving effect to such surrender.

         (c) ISSUANCE OF STOCK CERTIFICATES. In the event of any exercise of the
rights represented by this Warrant in accordance with and subject to the terms
and conditions hereof, (i) certificates for the shares of Warrant Stock so
purchased shall be dated the date of such exercise (if the deliveries required
to be made by the Holder pursuant to Section 2(b) are received by the Issuer
prior to 6:00 p.m. pacific time on the exercise date) and delivered to the
Holder hereof within a reasonable time, not exceeding three (3) Trading Days
after such exercise, and the Holder hereof shall be deemed for all purposes to
be the Holder of the shares of Warrant Stock so purchased as of the date of such
exercise, and (ii) unless this Warrant has expired, a new Warrant representing
the number of shares of Warrant Stock, if any, with respect to which this
Warrant shall not then have been exercised (less any amount thereof which shall
have been canceled in payment or partial payment of the Warrant Price as
hereinabove provided) shall also be issued to the Holder hereof at the Issuer's
expense within such time.

         (d) TRANSFERABILITY OF WARRANT. Subject to Section 2(e) and subject to
the provisions of the Purchase Agreement, this Warrant may be transferred by a
Holder without the consent of the Issuer. If transferred pursuant to this
paragraph and subject to the provisions of subsection (e) of this Section 2,
this Warrant may be transferred on the books of the Issuer by the Holder hereof
in person or by duly authorized attorney, upon surrender of this Warrant at the
principal office of the Issuer, properly endorsed (by the Holder executing an
assignment in the form attached hereto) and upon payment of any necessary
transfer tax or other governmental charge imposed upon such transfer. This
Warrant is exchangeable at the principal office of the Issuer for Warrants for
the purchase of the same aggregate number of shares of Warrant Stock, each new

                                      -2-
<PAGE>

Warrant to represent the right to purchase such number of shares of Warrant
Stock as the Holder hereof shall designate at the time of such exchange. All
Warrants issued on transfers or exchanges shall be dated the Original Issue Date
and shall be identical with this Warrant except as to the number of shares of
Warrant Stock issuable pursuant hereto.

         (e) COMPLIANCE WITH SECURITIES LAWS.

                  (i) The Holder of this Warrant, by acceptance hereof,
         acknowledges that this Warrant or the shares of Warrant Stock to be
         issued upon exercise hereof are being acquired solely for the Holder's
         own account and not as a nominee for any other party, and for
         investment, and that the Holder will not offer, sell or otherwise
         dispose of this Warrant or any shares of Warrant Stock to be issued
         upon exercise hereof except pursuant to an effective registration
         statement, or an exemption from registration, under the Securities Act
         and any applicable state securities laws.

                  (ii) Except as provided in paragraph (iii) below, this Warrant
         and all certificates representing shares of Warrant Stock issued upon
         exercise hereof shall be stamped or imprinted with a legend in
         substantially the following form:

                  THIS WARRANT AND THE SHARES OF COMMON STOCK ISSUABLE UPON
                  EXERCISE HEREOF HAVE NOT BEEN REGISTERED UNDER THE SECURITIES
                  ACT OF 1933, AS AMENDED (THE "SECURITIES ACT") OR ANY STATE
                  SECURITIES LAWS AND MAY NOT BE SOLD, TRANSFERRED OR OTHERWISE
                  DISPOSED OF UNLESS REGISTERED UNDER THE SECURITIES ACT AND
                  UNDER APPLICABLE STATE SECURITIES LAWS OR TELENETICS
                  CORPORATION SHALL HAVE RECEIVED AN OPINION OF ITS COUNSEL THAT
                  REGISTRATION OF SUCH SECURITIES UNDER THE SECURITIES ACT AND
                  UNDER THE PROVISIONS OF APPLICABLE STATE SECURITIES LAWS IS
                  NOT REQUIRED.

                  (iii) The restrictions imposed by this subsection (e) upon the
         transfer of this Warrant or the shares of Warrant Stock to be purchased
         upon exercise hereof shall terminate (A) when such securities shall
         have been resold pursuant to an effective registration statement under
         the Securities Act, (B) upon the Issuer's receipt of an opinion of
         counsel, in form and substance reasonably satisfactory to the Issuer,
         addressed to the Issuer to the effect that such restrictions are no
         longer required to ensure compliance with the Securities Act and state
         securities laws or (C) upon the Issuer's receipt of other evidence
         reasonably satisfactory to the Issuer that such registration and
         qualification under the Securities Act and state securities laws are
         not required. Whenever such restrictions shall cease and terminate as
         to any such securities, the Holder thereof shall be entitled to receive
         from the Issuer (or its transfer agent and registrar), without expense
         (other than applicable transfer taxes, if any), new Warrants (or, in
         the case of shares of Warrant Stock, new stock certificates) of like
         tenor not bearing the applicable legend required by paragraph (ii)
         above relating to the Securities Act and state securities laws.

                                      -3-
<PAGE>

         (f) CONTINUING RIGHTS OF HOLDER. The Issuer will, at the time of or at
any time after each exercise of this Warrant, upon the request of the Holder
hereof, acknowledge in writing the extent, if any, of its continuing obligation
to afford to such Holder all rights to which such Holder shall continue to be
entitled after such exercise in accordance with the terms of this Warrant,
PROVIDED that if any such Holder shall fail to make any such request, the
failure shall not affect the continuing obligation of the Issuer to afford such
rights to such Holder.

         3. STOCK FULLY PAID; RESERVATION AND LISTING OF SHARES; COVENANTS.

         (a) STOCK FULLY PAID. The Issuer represents, warrants, covenants and
agrees that, subject to Shareholder Approval (as defined in the Purchase
Agreement), all shares of Warrant Stock which may be issued upon the exercise of
this Warrant or otherwise hereunder will, upon issuance, be duly authorized,
validly issued, fully paid and non-assessable and free from all taxes, liens and
charges created by or through Issuer. The Issuer further covenants and agrees
that during the period within which this Warrant may be exercised, the Issuer
will at all times have authorized and reserved for the purpose of the issue upon
exercise of this Warrant a sufficient number of shares of Common Stock to
provide for the exercise of this Warrant.

         (b) RESERVATION. If any shares of Common Stock required to be reserved
for issuance upon exercise of this Warrant or as otherwise provided hereunder
require registration or qualification with any governmental authority under any
federal or state law before such shares may be so issued, the Issuer will in
good faith use its best efforts as expeditiously as possible at its expense to
cause such shares to be duly registered or qualified. If the Issuer shall list
any shares of Common Stock on any securities exchange or market it will, at its
expense, list thereon, maintain and increase when necessary such listing, of,
all shares of Warrant Stock from time to time issued upon exercise of this
Warrant or as otherwise provided hereunder, and, to the extent permissible under
the applicable securities exchange rules, all unissued shares of Warrant Stock
which are at any time issuable hereunder, so long as any shares of Common Stock
shall be so listed. The Issuer will also so list on each securities exchange or
market, and will maintain such listing of, any other securities which the Holder
of this Warrant shall be entitled to receive upon the exercise of this Warrant
if at the time any securities of the same class shall be listed on such
securities exchange or market by the Issuer.

         (c) COVENANTS. The Issuer shall not by any action including, without
limitation, amending the Articles of Incorporation or the by-laws of the Issuer,
or through any reorganization, transfer of assets, consolidation, merger,
dissolution, issue or sale of securities or any other 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 actions as may be necessary or appropriate to protect
the rights of the Holder hereof against dilution (to the extent specifically
provided herein) or impairment. Without limiting the generality of the
foregoing, the Issuer will (i) not permit the par value, if any, of its Common
Stock to exceed the then effective Warrant Price, (ii) not amend or modify any
provision of the Articles of Incorporation or by-laws of the Issuer in any
manner that would adversely affect in any way the powers, preferences or
relative participating, optional or other special rights of the Common Stock or
which would adversely affect the rights of the Holders of the Warrants, provided
that the Company shall not be prohibited from amending its Articles to increase

                                      -4-
<PAGE>

its authorized capital stock, (iii) take all such action as may be reasonably
necessary in order that the Issuer may validly and legally issue fully paid and
nonassessable shares of Common Stock, free and clear of any liens, claims,
encumbrances and restrictions (other than as provided herein) upon the exercise
of this Warrant, and (iv) use its best efforts to obtain all such
authorizations, exemptions or consents from any public regulatory body having
jurisdiction thereof as may be reasonably necessary to enable the Issuer to
perform its obligations under this Warrant.

         (d) LOSS, THEFT, DESTRUCTION OF WARRANTS. Upon receipt of evidence
satisfactory to the Issuer of the ownership of and the loss, theft, destruction
or mutilation of any Warrant and, in the case of any such loss, theft or
destruction, upon receipt of indemnity or security satisfactory to the Issuer
or, in the case of any such mutilation, upon surrender and cancellation of such
Warrant, the Issuer will make and deliver, in lieu of such lost, stolen,
destroyed or mutilated Warrant, a new Warrant of like tenor and representing the
right to purchase the same number of shares of Common Stock.

         (e) REGISTRATION RIGHTS. The Warrant Stock of the Issuer is entitled to
the benefits and subject to the terms of the Registration Rights Agreement dated
the date hereof between the Issuer and the Holder and shall carry standard
piggy-back registration rights on any registration statement filed by the Issuer
under the Securities Act other than on Form S-4 or Form S-8 (each as promulgated
under the Securities Act) or their then equivalents relating to equity
securities to be issued solely in connection with any acquisition of any entity
or business or equity securities issuable in connection with stock option or
other employee benefit plans.

         4. ADJUSTMENT OF WARRANT PRICE AND WARRANT SHARE NUMBER. The number of
shares of Common Stock for which this Warrant is exercisable, and the price at
which such shares may be purchased upon exercise of this Warrant, shall be
subject to adjustment from time to time as set forth in this Section 4. The
Issuer shall give the Holder notice of any event described below which requires
an adjustment pursuant to this Section 4 in accordance with Section 5.

         (a) RECAPITALIZATION, REORGANIZATION, RECLASSIFICATION, CONSOLIDATION,
MERGER OR SALE.

                  (i) In case the Issuer after the Original Issue Date shall do
         any of the following (each, a "TRIGGERING EVENT"): (a) consolidate with
         or merge into any other Person and the Issuer shall not be the
         continuing or surviving corporation of such consolidation or merger, or
         (b) permit any other Person to consolidate with or merge into the
         Issuer and the Issuer shall be the continuing or surviving Person but,
         in connection with such consolidation or merger, any Capital Stock of
         the Issuer shall be changed into or exchanged for Securities of any
         other Person or cash or any other property, or (c) transfer all or
         substantially all of its properties or assets to any other Person, or
         (d) effect a capital reorganization or reclassification of its Capital
         Stock, then, and in the case of each such Triggering Event, proper
         provision shall be made so that, upon the basis and the terms and in
         the manner provided in this Warrant, the Holder of this Warrant shall
         be entitled (x) upon the exercise hereof at any time after the
         consummation of such Triggering Event, to the extent this Warrant is
         not exercised prior to such Triggering Event, to receive at the Warrant
         Price in effect at the time immediately prior to the consummation of
         such Triggering Event in lieu of the Common Stock issuable upon such

                                      -5-
<PAGE>

         exercise of this Warrant prior to such Triggering Event, the
         Securities, cash and property to which such Holder would have been
         entitled upon the consummation of such Triggering Event if such Holder
         had exercised the rights represented by this Warrant immediately prior
         thereto, subject to adjustments (subsequent to such corporate action)
         as nearly equivalent as possible to the adjustments provided for
         elsewhere in this Section 4 or (y) to sell this Warrant (or, at such
         Holder's election, a portion hereof) concurrently with the Triggering
         Event to the Person continuing after or surviving such Triggering
         Event, or to the Issuer (if Issuer is the continuing or surviving
         Person) at a sales price equal to the amount of cash, property and/or
         Securities to which a holder of the number of shares of Common Stock
         which would otherwise have been delivered upon the exercise of this
         Warrant would have been entitled upon the effective date or closing of
         any such Triggering Event (the "EVENT CONSIDERATION"), less the amount
         or portion of such Event Consideration having a fair value equal to the
         aggregate Warrant Price applicable to this Warrant or the portion
         hereof so sold.

                  (ii) Notwithstanding anything contained in this Warrant to the
         contrary, the Issuer will not effect any Triggering Event unless, prior
         to the consummation thereof, each Person (other than the Issuer) which
         may be required to deliver any Securities, cash or property upon the
         exercise of this Warrant as provided herein shall assume, by written
         instrument delivered to, and reasonably satisfactory to, the Holder of
         this Warrant, (A) the obligations of the Issuer under this Warrant (and
         if the Issuer shall survive the consummation of such Triggering Event,
         such assumption shall be in addition to, and shall not release the
         Issuer from, any continuing obligations of the Issuer under this
         Warrant) and (B) the obligation to deliver to such Holder such shares
         of Securities, cash or property as, in accordance with the foregoing
         provisions of this subsection (a), such Holder shall be entitled to
         receive, and such Person shall have similarly delivered to such Holder
         an opinion of counsel for such Person, which counsel shall be
         reasonably satisfactory to such Holder, stating that this Warrant shall
         thereafter continue in full force and effect and the terms hereof
         (including, without limitation, all of the provisions of this
         subsection (a)) shall be applicable to the Securities, cash or property
         which such Person may be required to deliver upon any exercise of this
         Warrant or the exercise of any rights pursuant hereto.

                  (iii) If with respect to any Triggering Event, the Holder of
         this Warrant has exercised its right as provided in clause (y) of
         subparagraph (i) of this subsection (a) to sell this Warrant or a
         portion thereof, the Issuer agrees that as a condition to the
         consummation of any such Triggering Event the Issuer shall secure such
         right of Holder to sell this Warrant to the Person continuing after or
         surviving such Triggering Event and the Issuer shall not effect any
         such Triggering Event unless upon or prior to the consummation thereof
         the amounts of cash, property and/or Securities required under such
         clause (y) are delivered to the Holder of this Warrant. The obligation
         of the Issuer to secure such right of the Holder to sell this Warrant
         shall be subject to such Holder's cooperation with the Issuer,
         including, without limitation, the giving of customary representations
         and warranties to the purchaser in connection with any such sale. Prior
         notice of any Triggering Event shall be given to the Holder of this
         Warrant in accordance with Section 13 hereof.

                                      -6-
<PAGE>

         (b) STOCK DIVIDENDS, SUBDIVISIONS AND COMBINATIONS. If at any time the
Issuer shall:

                  (i) take a record of the holders of its Common Stock for the
         purpose of entitling them to receive a dividend payable in, or other
         distribution of, Additional Shares of Common Stock,

                  (ii) subdivide its outstanding shares of Common Stock into a
         larger number of shares of Common Stock, or

                  (iii) combine its outstanding shares of Common Stock into a
         smaller number of shares of Common Stock,

then (1) the number of shares of Common Stock for which this Warrant is
exercisable immediately after the occurrence of any such event shall be adjusted
to equal the number of shares of Common Stock which a record holder of the same
number of shares of Common Stock for which this Warrant is exercisable
immediately prior to the occurrence of such event would own or be entitled to
receive after the happening of such event, and (2) the Warrant Price then in
effect shall be adjusted to equal (A) the Warrant Price then in effect
multiplied by the number of shares of Common Stock for which this Warrant is
exercisable immediately prior to the adjustment divided by (B) the number of
shares of Common Stock for which this Warrant is exercisable immediately after
such adjustment.

         (c) CERTAIN OTHER DISTRIBUTIONS. If at any time the Issuer shall take a
record of the holders of its Common Stock for the purpose of entitling them to
receive any dividend or other distribution of:

                  (i) cash (other than a cash dividend payable out of earnings
         or earned surplus legally available for the payment of dividends under
         the laws of the jurisdiction of incorporation of the Issuer),

                  (ii) any evidences of its indebtedness, any shares of stock of
         any class or any other securities or property of any nature whatsoever
         (other than cash, Common Stock Equivalents or Additional Shares of
         Common Stock), or

                  (iii) any warrants or other rights to subscribe for or
         purchase any evidences of its indebtedness, any shares of stock of any
         class or any other securities or property of any nature whatsoever
         (other than cash, Common Stock Equivalents or Additional Shares of
         Common Stock),

then (1) the number of shares of Common Stock for which this Warrant is
exercisable shall be adjusted to equal the product of the number of shares of
Common Stock for which this Warrant is exercisable immediately prior to such
adjustment multiplied by a fraction (A) the numerator of which shall be the Per
Share Market Value of Common Stock at the date of taking such record and (B) the
denominator of which shall be such Per Share Market Value minus the amount
allocable to one share of Common Stock of any such cash so distributable and of
the fair value (as determined in good faith by the Board of Directors of the
Issuer and supported by an opinion from an investment banking firm of recognized
national standing acceptable to the Holder) of any and all such evidences of

                                      -7-
<PAGE>

indebtedness, shares of stock, other securities or property or warrants or other
subscription or purchase rights so distributable, and (2) the Warrant Price then
in effect shall be adjusted to equal (A) the Warrant Price then in effect
multiplied by the number of shares of Common Stock for which this Warrant is
exercisable immediately prior to the adjustment divided by (B) the number of
shares of Common Stock for which this Warrant is exercisable immediately after
such adjustment. A reclassification of the Common Stock (other than a change in
par value, or from par value to no par value or from no par value to par value)
into shares of Common Stock and shares of any other class of stock shall be
deemed a distribution by the Issuer to the holders of its Common Stock of such
shares of such other class of stock within the meaning of this Section 4(c) and,
if the outstanding shares of Common Stock shall be changed into a larger or
smaller number of shares of Common Stock as a part of such reclassification,
such change shall be deemed a subdivision or combination, as the case may be, of
the outstanding shares of Common Stock within the meaning of Section 4(b).

         (d) ISSUANCE OF ADDITIONAL SHARES OF COMMON STOCK.

                  (i) In the event the Issuer, shall, at any time, from time to
time, issue or sell any shares of Common Stock to a third party other than the
Holder of this Warrant or the Other Holders (as defined in the Purchase
Agreement) for a consideration per share less than the Warrant Price then in
effect for the Warrant immediately prior to the time of such issue or sale,
then, forthwith upon such issue or sale, the Warrant Price then in effect for
the Warrants shall be reduced to a price equal to the consideration per share
paid for such Common Stock and the number of shares of Common Stock for which
this Warrant is exercisable shall be increased by the product of the number of
shares of Common Stock for which this Warrant is exercisable immediately prior
to such issuance or sale multiplied by the Dilution Percentage. "Dilution
Percentage" shall mean the percentage by which the Warrant Price then in effect
is reduced pursuant to this Section 4(d).

                  (ii) If the Issuer, at any time while this Warrant is
outstanding, shall issue any Additional Shares of Common Stock to the Holder of
this Warrant (otherwise than as provided in the foregoing subsections (a)
through (c) of this Section 4), at a price per share less than the Warrant Price
then in effect or without consideration, then the Warrant Price upon each such
issuance shall be adjusted to that price determined by multiplying the Warrant
Price then in effect by a fraction:

                           (A) the numerator of which shall be equal to the sum
                  of (x) the number of shares of Common Stock outstanding
                  immediately prior to the issuance of such Additional Shares of
                  Common Stock PLUS (y) the number of shares of Common Stock
                  which the aggregate consideration for the total number of such
                  Additional Shares of Common Stock so issued would purchase at
                  a price per share equal to the greater of the Per Share Market
                  Value then in effect and the Warrant Price then in effect, and

                           (B) the denominator of which shall be equal to the

                  (iii) The provisions of paragraph (ii) of Section 4(d) shall
not apply to any issuance of Additional Shares of Common Stock for which an
adjustment is provided under Section 4(a) through 4(c). No adjustment of the
number of shares of Common Stock for which this Warrant shall be exercisable
shall be made under paragraph (ii) of Section 4(d) upon the issuance of any
Additional Shares of Common Stock which are issued pursuant to the exercise of
any Common Stock Equivalents, if any such adjustment shall previously have been
made upon the issuance of such Common Stock Equivalents (or upon the issuance of
any warrant or other rights therefor) pursuant to Section 4(f).

         (e) INTENTIONALLY OMITTED.

         (f) ISSUANCE OF COMMON STOCK EQUIVALENTS. If at any time the Issuer
shall take a record of the Holders of its Common Stock for the purpose of
entitling them to receive a distribution of, or shall in any manner (whether
directly or by assumption in a merger in which the Issuer is the surviving
corporation) issue or sell, any Common Stock Equivalents, whether or not the
rights to exchange or convert thereunder are immediately exercisable, and the
price per share for which Common Stock is issuable upon such conversion or
exchange shall be less than the Warrant Price in effect immediately prior to the
time of such issue or sale, then the number of shares of Common Stock for which
this Warrant is exercisable and the Warrant Price then in effect shall be
adjusted as provided in Section 4(d) on the basis that the maximum number of
Additional Shares of Common Stock necessary to effect the conversion or exchange
of all such Common Stock Equivalents shall be deemed to have been issued and
outstanding and the Issuer shall have received all of the consideration payable
therefor, if any, as of the date of actual issuance of such Common Stock
Equivalents. No further adjustments of the number of shares of Common Stock for
which this Warrant is exercisable and the Warrant Price then in effect shall be
made upon the actual issue of such Common Stock upon conversion or exchange of
such Common Stock Equivalents.

         (g) SUPERSEDING ADJUSTMENT. If, at any time after any adjustment of the
number of shares of Common Stock for which this Warrant is exercisable and the
Warrant Price then in effect shall have been made pursuant to Section 4(f) as
the result of any issuance of warrants, other rights or Common Stock
Equivalents, and (i) such warrants or other rights, or the right of conversion
or exchange in such other Common Stock Equivalents, shall expire, and all or a
portion of such warrants or other rights, or the right of conversion or exchange
with respect to all or a portion of such other Common Stock Equivalents, as the
case may be shall not have been exercised, or (ii) the consideration per share
for which shares of Common Stock are issuable pursuant to such Common Stock
Equivalents, shall be increased solely by virtue of provisions therein contained
for an automatic increase in such consideration per share upon the occurrence of
a specified date or event, then for each outstanding Warrant such previous
adjustment shall be rescinded and annulled and the Additional Shares of Common
Stock which were deemed to have been issued by virtue of the computation made in
connection with the adjustment so rescinded and annulled shall no longer be
deemed to have been issued by virtue of such computation. Upon the occurrence of
an event set forth in this Section 4(g) above, there shall be a recomputation
made of the effect of such Common Stock Equivalents on the basis of: (i)
treating the number of Additional Shares of Common Stock or other property, if
any, theretofore actually issued or issuable pursuant to the previous exercise
of any such warrants or other rights or any such right of conversion or
exchange, as having been issued on the date or dates of any such exercise and

                                      -9-
<PAGE>

for the consideration actually received and receivable therefor, and (ii)
treating any such Common Stock Equivalents which then remain outstanding as
having been granted or issued immediately after the time of such increase of the
consideration per share for which shares of Common Stock or other property are
issuable under such Common Stock Equivalents; whereupon a new adjustment of the
number of shares of Common Stock for which this Warrant is exercisable and the
Warrant Price then in effect shall be made, which new adjustment shall supersede
the previous adjustment so rescinded and annulled.

         (h) PURCHASE OF COMMON STOCK BY THE ISSUER. If the Issuer at any time
while this Warrant is outstanding shall, directly or indirectly through a
Subsidiary or otherwise, purchase, redeem or otherwise acquire any shares of
Common Stock at a price per share greater than the Per Share Market Value, then
the Warrant Price upon each such purchase, redemption or acquisition shall be
adjusted to that price determined by multiplying such Warrant Price by a
fraction (i) the numerator of which shall be the number of shares of Common
Stock outstanding immediately prior to such purchase, redemption or acquisition
minus the number of shares of Common Stock which the aggregate consideration for
the total number of such shares of Common Stock so purchased, redeemed or
acquired would purchase at the Per Share Market Value; and (ii) the denominator
of which shall be the number of shares of Common Stock outstanding immediately
after such purchase, redemption or acquisition. For the purposes of this
subsection (h), the date as of which the Per Share Market Price shall be
computed shall be the earlier of (x) the date on which the Issuer shall enter
into a firm contract for the purchase, redemption or acquisition of such Common
Stock, or (y) the date of actual purchase, redemption or acquisition of such
Common Stock. For the purposes of this subsection (h), a purchase, redemption or
acquisition of a Common Stock Equivalent shall be deemed to be a purchase of the
underlying Common Stock, and the computation herein required shall be made on
the basis of the full exercise, conversion or exchange of such Common Stock
Equivalent on the date as of which such computation is required hereby to be
made, whether or not such Common Stock Equivalent is actually exercisable,
convertible or exchangeable on such date.

         (i) OTHER PROVISIONS APPLICABLE TO ADJUSTMENTS UNDER THIS SECTION. The
following provisions shall be applicable to the making of adjustments of the
number of shares of Common Stock for which this Warrant is exercisable and the
Warrant Price then in effect provided for in this Section 4:

                  (i) COMPUTATION OF CONSIDERATION. To the extent that any
Additional Shares of Common Stock or any Common Stock Equivalents (or any
warrants or other rights therefor) shall be issued for cash consideration, the
consideration received by the Issuer therefor shall be the amount of the cash
received by the Issuer therefor, or, if such Additional Shares of Common Stock
or Common Stock Equivalents are offered by the Issuer for subscription, the
subscription price, or, if such Additional Shares of Common Stock or Common
Stock Equivalents are sold to underwriters or dealers for public offering
without a subscription offering, the initial public offering price (in any such
case subtracting any amounts paid or receivable for accrued interest or accrued
dividends and without taking into account any compensation, discounts or
expenses paid or incurred by the Issuer for and in the underwriting of, or
otherwise in connection with, the issuance thereof). To the extent that such
issuance shall be for a consideration other than cash, then, except as herein
otherwise expressly provided, the amount of such consideration shall be deemed
to be the fair value of such consideration at the time of such issuance as

                                      -10-
<PAGE>

determined in good faith by the Board of Directors of the Issuer. In case any
Additional Shares of Common Stock or any Common Stock Equivalents (or any
warrants or other rights therefor) shall be issued in connection with any merger
in which the Issuer issues any securities, the amount of consideration therefor
shall be deemed to be the fair value, as determined in good faith by the Board
of Directors of the Issuer, of such portion of the assets and business of the
nonsurviving corporation as such Board in good faith shall determine to be
attributable to such Additional Shares of Common Stock, Common Stock
Equivalents, or any warrants or other rights therefor, as the case may be. The
consideration for any Additional Shares of Common Stock issuable pursuant to any
warrants or other rights to subscribe for or purchase the same shall be the
consideration received by the Issuer for issuing such warrants or other rights
plus the additional consideration payable to the Issuer upon exercise of such
warrants or other rights. The consideration for any Additional Shares of Common
Stock issuable pursuant to the terms of any Common Stock Equivalents shall be
the consideration received by the Issuer for issuing warrants or other rights to
subscribe for or purchase such Common Stock Equivalents, plus the consideration
paid or payable to the Issuer in respect of the subscription for or purchase of
such Common Stock Equivalents, plus the additional consideration, if any,
payable to the Issuer upon the exercise of the right of conversion or exchange
in such Common Stock Equivalents. In case of the issuance at any time of any
Additional Shares of Common Stock or Common Stock Equivalents in payment or
satisfaction of any dividends upon any class of stock other than Common Stock,
the Issuer shall be deemed to have received for such Additional Shares of Common
Stock or Common Stock Equivalents a consideration equal to the amount of such
dividend so paid or satisfied.

                  (ii) WHEN ADJUSTMENTS TO BE MADE. The adjustments required by
this Section 4 shall be made whenever and as often as any specified event
requiring an adjustment shall occur, except that any adjustment of the number of
shares of Common Stock for which this Warrant is exercisable that would
otherwise be required may be postponed (except in the case of a subdivision or
combination of shares of the Common Stock, as provided for in Section 4(b)) up
to, but not beyond the date of exercise if such adjustment either by itself or
with other adjustments not previously made adds or subtracts less than one
percent (1%) of the shares of Common Stock for which this Warrant is exercisable
immediately prior to the making of such adjustment. Any adjustment representing
a change of less than such minimum amount (except as aforesaid) which is
postponed shall be carried forward and made as soon as such adjustment, together
with other adjustments required by this Section 4 and not previously made, would
result in a minimum adjustment or on the date of exercise. For the purpose of
any adjustment, any specified event shall be deemed to have occurred at the
close of business on the date of its occurrence.

                  (iii) FRACTIONAL INTERESTS. In computing adjustments under
this Section 4, fractional interests in Common Stock shall be taken into account
to the nearest one one-hundredth (1/100th) of a share.

                  (iv) WHEN ADJUSTMENT NOT REQUIRED. If the Issuer shall take a
record of the holders of its Common Stock for the purpose of entitling them to
receive a dividend or distribution or subscription or purchase rights and shall,
thereafter and before the distribution to stockholders thereof, legally abandon
its plan to pay or deliver such dividend, distribution, subscription or purchase
rights, then thereafter no adjustment shall be required by reason of the taking

                                      -11-
<PAGE>

of such record and any such adjustment previously made in respect thereof shall
be rescinded and annulled. In addition, no adjustment shall be required under
Section 4(d)(i) hereof in the event the Issuer issues or sells Additional Shares
in a transaction whose primary purpose is to establish a relationship with the
recipient thereof for strategic reasons and not to raise capital. Further,
anything herein to the contrary notwithstanding, the Issuer shall not be
required to make any adjustment of the number of shares of Common Stock issuable
upon exercise of this Warrant upon the grant or the exercise of, options or
warrants or rights to purchase stock under the Issuer's existing stock option
and stock purchase plans or upon the issuance to the Holder or the Other Holders
or their successors or assigns of replacement securities pursuant to Section
3.10(c) of the Purchase Agreement.

         (k) FORM OF WARRANT AFTER ADJUSTMENTS. The form of this Warrant need
not be changed because of any adjustments in the Warrant Price or the number and
kind of Securities purchasable upon the exercise of this Warrant.

         (l) ESCROW OF WARRANT STOCK. If after any property becomes
distributable pursuant to this Section 4 by reason of the taking of any record
of the holders of Common Stock, but prior to the occurrence of the event for
which such record is taken, and the Holder exercises this Warrant, any shares of
Common Stock issuable upon exercise by reason of such adjustment shall be deemed
the last shares of Common Stock for which this Warrant is exercised
(notwithstanding any other provision to the contrary herein) and such shares or
other property shall be held in escrow for the Holder by the Issuer to be issued
to the Holder upon and to the extent that the event actually takes place, upon
payment of the current Warrant Price. Notwithstanding any other provision to the
contrary herein, if the event for which such record was taken fails to occur or
is rescinded, then such escrowed shares shall be cancelled by the Issuer and
escrowed property returned.

         5. NOTICE OF ADJUSTMENTS. Whenever the Warrant Price or Warrant Share
Number shall be adjusted pursuant to Section 4 hereof (for purposes of this
Section 5, each an "adjustment"), the Issuer shall cause its Chief Financial
Officer to prepare and execute 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 (including a description of the
basis on which the Board made any determination hereunder), and the Warrant
Price and Warrant Share Number after giving effect to such adjustment, and shall
cause copies of such certificate to be delivered to the Holder of this Warrant
promptly after each adjustment. Any dispute between the Issuer and the Holder of
this Warrant with respect to the matters set forth in such certificate may at
the option of the Holder of this Warrant be submitted to one of the national
accounting firms currently known as the "big five" selected by the Holder,
PROVIDED that the Issuer shall have ten (10) days after receipt of notice from
such Holder of its selection of such firm to object thereto, in which case such
Holder shall select another such firm and the Issuer shall have no such right of
objection. The firm selected by the Holder of this Warrant as provided in the
preceding sentence shall be instructed to deliver a written opinion as to such
matters to the Issuer and such Holder within thirty (30) days after submission
to it of such dispute. Such opinion shall be final and binding on the parties
hereto. The fees and expenses of such accounting firm shall be paid by the
Issuer.

                                      -12-
<PAGE>

         6. FRACTIONAL SHARES. No fractional shares of Warrant Stock will be
issued in connection with an exercise hereof, but in lieu of such fractional
shares, the Issuer shall make a cash payment therefor equal in amount to the
product of the applicable fraction multiplied by the Per Share Market Value then
in effect.

         7. OWNERSHIP CAP AND CERTAIN EXERCISE RESTRICTIONS.

         (a) Notwithstanding anything to the contrary set forth in this Warrant,
at no time may a holder of this Warrant exercise this Warrant if the number of
shares of Common Stock to be issued pursuant to such exercise would exceed, when
aggregated with all other shares of Common Stock owned by such holder at such
time, the number of shares of Common Stock which would result in such holder
owning more than 4.999% of all of the Common Stock outstanding at such time;
provided, however, that upon a holder of this Warrant providing the Issuer with
sixty (60) days notice (pursuant to Section 13 hereof) (the "Waiver Notice")
that such holder would like to waive this Section 7(a) with regard to any or all
shares of Common Stock issuable upon exercise of this Warrant, this Section 7(a)
will be of no force or effect with regard to all or a portion of the Warrant
referenced in the Waiver Notice.

         (b) The Holder may not exercise the Warrant hereunder to the extent
such exercise would result in the Holder beneficially owning (as determined in
accordance with Section 13(d) of the Exchange Act and the rules thereunder) in
excess of 9.999% of the then issued and outstanding shares of Common Stock,
including shares issuable upon exercise of the Warrant held by the Holder after
application of this Section.

two (2) Trading Days written notice thereof describing the matters upon which
action is to be taken). The Holder shall have the right to send two (2)
representatives selected by it to each meeting, who shall be permitted to
attend, but not vote at, such meeting and any adjournments thereof. This Warrant
entitles the Holder to receive copies of all financial and other information
distributed or required to be distributed to the holders of the Common Stock.
