                                       2

<Page>

                  2.2 EXERCISE PROCEDURE. To exercise this Warrant, the
Warrantholder shall deliver to the Company at its address set forth in SECTION
10.5: (a) payment of the aggregate Exercise Price in the manner provided in
SECTION 2.3 (as computed by multiplying (A) the Exercise Price as of such date
by (B) the number of shares of Common Stock for which the Warrantholder is
exercising this Warrant at such time); (b) a completed and properly executed
Notice of Exercise in substantially the form attached hereto as ANNEX I; and (c)
this Warrant. Upon receipt of the aggregate Exercise Price and the required
deliverables pursuant to the preceding sentence, the Company shall, within five
(5) Business Days thereafter, subject to receipt of any required regulatory
approvals (including expiration of any required waiting period), deliver to the
Warrantholder duly executed certificate(s) representing the aggregate number of
shares of Common Stock issuable upon such exercise, together with cash in lieu
of any fraction of a Warrant Share as provided in SECTION 2.8. Such stock
certificate(s) shall be in such denominations and registered in the name(s) set
forth in the Notice of Exercise. If this Warrant shall have been exercised in
part, the Company shall deliver to the Warrantholder a new warrant evidencing
the rights of the Warrantholder to purchase the remaining Warrant Shares
issuable (which shall in all other respects be identical to this Warrant).

                  2.3 PAYMENT OF EXERCISE PRICE. The Exercise Price may be
payable hereunder by the delivery by certified check or by wire transfer of
immediately available funds to the account of the Company of an amount equal to
the Exercise Price. The Warrantholder may elect to exercise the Warrant in a
cashless exercise in lieu of payment of an amount equal to the Exercise Price,
pursuant to which the Warrantholder will receive that number of shares of Common
Stock equal to the quotient obtained by dividing (A-B)(C) by A where:

                  (A) = the Fair Market Value of one share of Common Stock on
                  the date that the Warrantholder delivers the Notice of
                  Exercise;

                  (B) = the Exercise Price for one share of Common Stock under
                  this Warrant (as adjusted to the date of such calculation);
                  and

                  (C) = the number of Warrant Shares issuable upon exercise of
                  this Warrant or, if only a portion of the Warrant is being
                  exercised, the number of Warrant Shares to be acquired as set
                  forth in the Notice of Exercise (at the date of such
                  calculation).

If the above calculation results in a negative number, then no Warrant Shares
shall be issued or issuable upon exercise of this Warrant.

                  2.4 WARRANT SHARES. If Revenue achieved during the Warrant
Period is $7,000,000 or greater, then the number of Warrant Shares shall be Two
Hundred and Fifty Thousand (250,000). If Revenue achieved during the Warrant
Period is less than $7,000,000, then the number of Warrant Shares shall be zero.
In the case of the number of Warrant Shares equals zero, then this Warrant shall
not be exercisable for any shares of Common Stock and this Warrant shall be of
no further force and effect. "REVENUE" shall be determined in accordance with
the procedures and methods set forth in Annex II attached hereto.

                  2.5 EXERCISE UPON CERTAIN CONDITIONS. The Warrantholder may
immediately exercise this Warrant and the number of Warrant Shares shall be
equal to Two Hundred and Fifty Thousand (250,000) upon the Company's (i) sale or
disposal of all or substantially all of the Acquired Assets (as defined in the
Asset Purchase Agreement); or (ii) consummation of any Capital Event..

                  2.6 RESTRICTIONS. (a) The Company shall not be required to
issue any shares of Common Stock under this Warrant if the issuance of such
shares would constitute a violation by the Company of any provision of any law,
rule or regulation of (i) any governmental authority, including without
limitation, compliance with the registration or qualification requirement of
applicable federal and

                                       3

<Page>

state securities laws or (ii) any applicable self governing organization or
stock exchange, including without limitation, the rules, regulations or listing
requirements of The Nasdaq Stock Market or the SWX Swiss Exchange. If at any
time the Company shall determine, based upon the advice of securities counsel,
that the registration, qualification or listing of any shares subject to this
Warrant under any applicable state or federal law or other applicable rules or
regulations (including those of Nasdaq or the SWX Swiss Exchange) is necessary
as a condition of, or in connection with, the issuance of shares, the Company
shall not be required to issue any shares of Common Stock under this Warrant
unless the Company has received evidence reasonably satisfactory to it that (A)
in connection with the Securities Act, a registration statement under the
Securities Act is in effect with respect to such shares or the holder of this
Warrant may acquire such shares pursuant to an exemption from registration under
the Securities Act, and (B) in connection with the SWX Swiss Exchange, such
shares have been properly listed on the SWX Exchange.

                  (b) If the Warrantholder has not paid in full (in the manner
and in accordance with the terms of the Asset Purchase Agreement or as otherwise
agreed by the Company and the Warrantholder), any amounts owed to the Company
pursuant to Section 8 of the Asset Purchase Agreement and the Warrantholder
elects to exercise this Warrant during the pendency of any such outstanding
deficiency, then the aggregate Exercise Price in effect immediately prior to
such time will be increased (solely for purposes of this paragraph 2.6(b)) by
the deficient amount owed to the Company by the Warrantholder. Notwithstanding
the foregoing, and except as otherwise set forth in Section 8(b)(v) of the Asset
Purchase Agreement, if any such deficiency has not been finally resolved, paid
or settled at the conclusion of the Exercise Period, then the Warrantholder may
not exercise this Warrant and the Company shall not be required to issue any
shares of Common Stock under this Warrant. Neither the exercise of nor the
failure to exercise this right will constitute an election of remedies or limit
the Company in any manner in the enforcement of any other remedies that may be
available to the Company.

                  2.7 PAYMENT OF TAXES. The Company shall pay all stamp taxes
and other similar charges with respect to the issue or delivery of Common Stock
hereunder. The Company shall not be required to pay any transfer tax or other
similar charge imposed in connection with the issue of any stock certificate in
any name other than that of the Warrantholder, and in such case the Company
shall not be required to issue or deliver any stock certificate until such tax
or other charge has been paid or it has been established to the reasonable
satisfaction of the Company that no such tax or other charge is due.

                  2.8 FRACTIONAL SHARES. The Company shall not be required to
issue any fractional shares of Common Stock upon exercise of this Warrant. In
lieu of any fractional share to which the Warrantholder would otherwise be
entitled upon exercise of this Warrant, the Company shall make a cash payment in
an amount equal to the product of (a) the Fair Market Value per share of Common
Stock on the date of exercise MULTIPLIED by (b) the fraction of a share.

III. ADJUSTMENTS

                  3.1 INTRODUCTION. The number of Warrant Shares and the
Exercise Price of this Warrant shall be subject to adjustment from time to time
as set forth in this ARTICLE III. The Company shall give the Warrantholder
notice of any event described below which requires an adjustment pursuant to
this ARTICLE III.

                  3.2 ADJUSTMENT OF EXERCISE PRICE AND WARRANT SHARES FOR STOCK
DIVIDENDS, SUBDIVISIONS AND COMBINATIONS. If at any time during the Exercise
Period the Company shall: (a) declare a dividend payable in, or other
distribution to all holders of Outstanding shares of Common Stock of, Common
Stock; (b) subdivide or split its Outstanding shares of Common Stock into a
larger number of shares of Common Stock; or (c) combine or reclassify its
Outstanding shares of Common Stock into a smaller number of shares of Common
Stock, then: (i) the number of Warrant Shares for which this Warrant is
exercisable upon the occurrence of any such event shall be adjusted to equal the

                                       4

<Page>

product of (A) the number of such Warrant Shares without giving effect to such
event MULTIPLIED by (B) a fraction, the numerator of which is the number of
Outstanding shares of Common Stock after giving effect to such event and the
denominator of which is the number of Outstanding shares of Common Stock without
giving effect to such event; and (ii) the Exercise Price shall be adjusted to
equal the product of (A) the Exercise Price without giving effect to such
adjustment MULTIPLIED by (B) a fraction, the numerator of which is the number of
Warrant Shares without giving effect to such event and the denominator of which
is the number of Warrant Shares after giving effect to such event.

                  3.3 ADJUSTMENT OF EXERCISE PRICE AND WARRANT SHARES UPON
CERTAIN DISTRIBUTIONS. If, at any time during the Exercise Period, the Company
shall distribute to all holders of shares of Common Stock cash, evidences of
indebtedness of the Company or another issuer, securities of the Company or
another issuer, or other assets or rights or warrants to subscribe for or
purchase securities of the Company, in each case excluding distributions that
result in adjustment pursuant to SECTION 3.2 (the "DISTRIBUTED ITEMS"), then the
Exercise Price shall be adjusted according to the following formula:

<Table>
<S>              <C>
Exercise Price = Exercise Price x (Fair Market Value of a Warrant Share - FMV of Distributed Items)
                 ----------------------------------------------------------------------------------
                                   Fair Market Value of a Warrant Share
</Table>

                  For purposes of this SECTION 3.3, the term "FMV OF DISTRIBUTED
ITEMS" shall mean the fair market value of the Distributed Items to which the
holder of one share of Common Stock would be entitled to receive in such
distribution, as determined by the Board of Directors in good faith exercising
its fiduciary duties. Upon the occurrence of an adjustment of the Exercise Price
pursuant to this SECTION 3.3, the number of Warrant Shares shall be adjusted
according to the following formula:

      Warrant Shares = Warrant Shares x Exercise Price (without adjustment)
                       ----------------------------------------------------
                          Exercise Price (giving effect to adjustment)

                  3.4 WHEN ADJUSTMENTS ARE TO BE MADE. Adjustments pursuant to
this ARTICLE III shall be made whenever and as often as any event necessitating
an adjustment shall occur, except that any such adjustment may be postponed
until the earlier of: (a) three (3) years following the date of such event; or
(b) the date of exercise of this Warrant, if such adjustment either by itself or
together with other such adjustments not previously made would add or subtract
less than one percent (1%) of the number of Warrant Shares for which this
Warrant is exercisable immediately prior to the making of such adjustment. Any
such postponed adjustment shall be carried forward and made on the earliest of:
(x) the date of exercise of this Warrant; (y) the date on which such postponed
adjustment, together with any other required but unmade adjustments, would
result in an adjustment of sufficient magnitude to be required to be made
pursuant to this SECTION 3.4; or (z) three (3) years following the date of the
event necessitating the adjustment. For the purpose of this SECTION 3.4, an
event necessitating an adjustment shall be deemed to have occurred at the close
of business on the date of its occurrence.

IV. NOTICES TO THE WARRANTHOLDER

                  4.1 NOTICE OF CAPITAL EVENT. If, at any time during the

the Company: (a) setting forth, in reasonable detail, the circumstances
surrounding the Capital Event; (b) the time, if any such time is to be fixed, as

securities or property for which the warrant of the Successor (as defined in

SECTION 5.1 upon the transferability of this Warrant and the Warrant Shares
shall terminate: (a) when and so long as this Warrant or such Warrant Shares

of counsel reasonably satisfactory to it that this Warrant or such Warrant
Shares may be transferred without registration thereof under the Securities Act;
PROVIDED, HOWEVER, that if the Warrant or the Warrant Shares have been held
(both legally and beneficially) by the Warrantholder for at least one (1) year
and are proposed to be sold in compliance with Rule 144 under the Securities
Act, no such opinion of counsel shall be required. Whenever the legend
requirements imposed by SECTION 5.1 shall terminate as to this Warrant or any
Warrant Shares, the holder of this Warrant or such Warrant Shares shall be
entitled to receive from the Company, at the Company's expense, a new warrant or
a new stock certificate representing such Warrant Shares, as the case may be,
not bearing the restrictive legend described in SECTION 5.1.

acceptance hereof, represents to the Company that this Warrant and any Warrant
Shares purchased upon exercise of this Warrant are being acquired solely for the
Warrantholder's own account and not as a nominee for any other party, and for
investment, and that the Warrantholder will not offer, sell or otherwise dispose
of this Warrant or any such Warrant Shares except under circumstances that will
not result in a violation of the Securities Act or any applicable state
securities laws. Upon exercise of all or part of this Warrant, the Warrantholder
shall, if requested by the Company, confirm in writing, in a form reasonably
satisfactory to counsel of the Company, the foregoing representations and other
representations regarding the Warrantholder's status as an accredited or
sophisticated investor (as defined under Rules 501(a) and 506(b)(ii),

requested by the Company.

taxes payable upon the making of such transfer and, if required, an opinion of
counsel reasonably acceptable to counsel of the Company in its professional
determination concerning the compliance of such transfer with the Securities Act
and applicable state securities laws. Upon receipt of such items, the Company
shall execute and deliver a new warrant or warrants in the name of the assignee
or assignees and in the denomination(s) specified in such instrument of
assignment, and shall issue to the assignor a new warrant evidencing the portion
of this Warrant not so assigned, and this Warrant shall promptly be cancelled.

                  5.5 MAINTENANCE OF TRANSFER BOOKS. The Company agrees to
maintain, at the principal office of the Company at the address set forth in
SECTION 10.5, books or records for the registration and the registration of

Upon the consummation of any Capital Event, the successor or acquiring Person
(the "SUCCESSOR") to or in such Capital Event shall issue to the Warrantholder a
new warrant of the Successor which shall include all material terms of this
Warrant, including without limitation the provisions of Section 2.4 regarding
vesting and exercise, except that such warrant shall provide for the purchase
(upon satisfaction of the relevant vesting criteria under Section 2.4), at the
Exercise Price per share, instead of the number of shares of Common Stock
issuable hereunder, of the kind and amount of shares of common stock or other
securities or cash or other property of the Successor that would be received by
a holder of such number of shares of Common Stock in such Capital Event.

                  6.2 SUCCESSIVE CAPITAL EVENTS. The provisions of this

the Company to perform its obligations under this Warrant (including, without
limitation, making all necessary filings with such Governmental Authorities);

amendments to its certificate of incorporation) to ensure that the Company has
authorized a sufficient number of authorized but unissued shares of its common
stock to provide for the issuance of the Warrant Shares; (c) reserve from such

Warrantholder and each holder of Warrant Shares in supplying such information as

                                    ANNEX II

                                 ---------------

                            DETERMINATION OF REVENUE

         This Annex II contains the criteria used to determine "Revenue" for
purposes of Section 2.4 of the Warrant issued by e-centives, Inc., a Delaware
corporation (the "COMPANY"), in favor of BrightStreet.com, Inc., a Delaware
corporation (the "WARRANTHOLDER"), to which this Annex II is attached. Any
capitalized term not defined in this Annex II shall have the meaning assigned to
the term in the Warrant. Notwithstanding anything herein to the contrary, the
Company agrees to operate the Business in good faith and will take no action
specifically designed to circumvent the Revenues Test and Product Performance
Test.

I. REVENUES TEST

         A. The term "BUSINESS" as used in this Annex II means the business and
assets of the Warrantholder acquired pursuant to the Asset Purchase Agreement.
Except as specifically provided in this Annex II, the Business shall not include
any other business or assets of any other business entity owned or acquired by
Company during the Warrant Period, unless otherwise agreed in writing by the
Company and the Warrantholder.

         B. For purposes of this Annex II, revenue ("REVENUE") of the Business
for the Warrant Period shall be determined in the following manner. All
determinations of Revenue shall be made in accordance with GAAP, applied in a
manner consistent with the financial statements of the Company, and shall be net
of any actual returns or actual bad debt expense.

                           1. The Company shall determine the revenues from the
licensing or sale of any of the products or functionality included in the
Business acquired from the Warrantholder (the "ACQUIRED
PRODUCTS/FUNCTIONALITY"), and offered by the Company on a stand-alone basis. All
of these amounts shall be included in "Revenue."

                           2. In the case of Acquired Products/Functionality
offered by the Company as incorporated into or in conjunction with other
products or services of the Company such that the revenues solely attributable
to the Acquired Products/Functionality cannot readily be determined by the
Company ("COMBINED PRODUCTS/FUNCTIONALITY"), the Company shall make a reasonable
allocation of the revenues realized from the licensing or sale of Combined
Products/Functionality between the Acquired Products/Functionality and other
products or services of the Company based upon the respective functions
performed by each, their fair market value and/or other appropriate method
applicable to a particular product or functionality, in each case acting in good
faith and consistently with other similar allocations made by the Company
hereunder or for other purposes. "Revenue" shall include the portion of the net
revenues from the licensing or sale of Combined Products/Functionality so
allocated to the Acquired Products/Functionality.

                           3. In the case of each contract entered into within
the Warrant Period, where the Company has a legal right to receive revenue from
the licensing or sale of Acquired Products/Functionality or Combined
Products/Functionality after the Warrant Period, but where such right is not
considered revenue for the Warrant Period under applicable GAAP revenue
recognition principles ("UNREALIZED CONTRACTS"), the Company shall determine the
applicable revenues (under paragraph 1 or 2 above, as applicable) which it is
legally entitled to receive under such Unrealized Contracts without further
action on the part of the customer (such as the exercise of any options to
purchase products beyond those legally committed to in the contract). The
Company shall then (i) apply a reasonable discount to such revenues to reflect
the fact that they will be received after the end of the applicable period,
which discount shall be based on the Company's cost of funds

                                       13

<Page>

at such time (or, if not determinable, the cost of funds for similarly situated
companies as reasonably determined by the Company's financial adviser), (ii)
reduce such revenues by a probability factor that reflects any applicable
uncertainties regarding the Company's ability to perform the Unrealized Contract
and become entitled to the revenues and (iii) reduce such revenues by a
probability factor that reflects any applicable uncertainties or externalities
regarding the ability of a customer who is a party to such Unrealized Contract
to perform the Unrealized Contract and entitle the Company to realize revenues,
it being understood that all of the foregoing reductions shall be multiplicative
in application, and not additive. The resulting amount (the "CONTRACT VALUE")
for each Unrealized Contract shall be included in "Revenue."

                  4. A computation of the Revenues for the Warrant Period will
be prepared by the Company in the form of a report in accordance with the
foregoing principles and delivered to the Warrantholder within forty-five (45)
days after completion of the Warrant Period.

                                                                       Exhibit B

                  (A) = the Fair Market Value of one share of Common Stock on
                  the date that the Warrantholder delivers the Notice of
                  Exercise;

                  (B) = the Exercise Price for one share of Common Stock under
                  this Warrant (as adjusted to the date of such calculation);
                  and

                  (C) = the number of Warrant Shares issuable upon exercise of
                  this Warrant or, if only a portion of the Warrant is being
                  exercised, the number of Warrant Shares to be acquired as set
                  forth in the Notice of Exercise (at the date of such
                  calculation).

If the above calculation results in a negative number, then no Warrant Shares
shall be issued or issuable upon exercise of this Warrant.

                  2.4 EXERCISE UPON CERTAIN CONDITIONS. The Warrantholder may
immediately exercise this Warrant and the number of Warrant Shares shall be
equal to Five Hundred Thousand (500,000) upon the Company's (i) sale or disposal
of all or substantially all of the Acquired Assets (as defined in the Asset
Purchase Agreement); or (ii) consummation of any Capital Event.

                  2.5 RESTRICTIONS. (a) The Company shall not be required to
issue any shares of Common Stock under this Warrant if the issuance of such
shares would constitute a violation by the Company of any provision of any law,
rule or regulation of (i) any governmental authority, including without
limitation, compliance with the registration or qualification requirement of
applicable federal and state securities laws or (ii) any applicable self
governing organization or stock exchange, including without limitation, the
rules, regulations or listing requirements of The Nasdaq Stock Market or the SWX
Swiss Exchange. If at any time the Company shall determine, based upon the
advice of securities counsel, that the registration, qualification or listing of
any shares subject to this Warrant under any applicable state or federal law or
other applicable rules or regulations (including those of Nasdaq or the SWX
Swiss Exchange) is necessary as a condition of, or in connection with, the
issuance of shares, the Company shall not be required to issue any shares of
Common Stock under this Warrant unless the Company has received evidence
reasonably satisfactory to it that (A) in connection with the Securities Act, a
registration statement under the Securities Act is in effect with respect to
such shares or the holder of this Warrant may acquire such shares pursuant to an
exemption from registration under the Securities Act, and (B) in connection with
the SWX Swiss Exchange, such shares have been properly listed on the SWX
Exchange.

                  (b) If the Warrantholder has not paid in full (in the manner
and in accordance with the terms of the Asset Purchase Agreement or as otherwise
agreed by the Company and the Warrantholder), any amounts owed to the Company
pursuant to Section 8 of the Asset Purchase Agreement and the Warrantholder
elects to exercise this Warrant during the pendency of any such outstanding
deficiency, then the aggregate Exercise Price in effect immediately prior to
such time will be increased (solely for purposes of this paragraph 2.5(b)) by
the deficient amount owed to the Company by the Warrantholder. Notwithstanding
the foregoing, and except as otherwise set forth in Section 8(b)(v) of the Asset
Purchase Agreement, if any such deficiency has not been finally resolved, paid
or settled at the conclusion of the Exercise Period, then the Warrantholder may
not exercise this Warrant and the Company shall not be required to issue any
shares of Common Stock under this Warrant. Neither the exercise of nor the
failure to exercise this right will constitute an election of remedies or limit
the Company in any manner in the enforcement of any other remedies that may be
available to the Company.

                  2.6 PAYMENT OF TAXES. The Company shall pay all stamp taxes
and other similar charges with respect to the issue or delivery of Common Stock
hereunder. The Company shall not be required to pay any transfer tax or other
similar charge imposed in connection with the issue of any stock certificate in
any name other than that of the Warrantholder, and in such case the Company
shall not be required to issue or deliver any stock certificate until such tax
or other charge has been paid or it has been established to the reasonable
satisfaction of the Company that no such tax or other charge is due.

                  2.7 FRACTIONAL SHARES. The Company shall not be required to
issue any fractional shares of Common Stock upon exercise of this Warrant. In
lieu of any fractional share to which the Warrantholder would otherwise be
entitled upon exercise of this Warrant, the Company shall make a cash payment in
an amount equal to the product of (a) the Fair Market Value per share of Common
Stock on the date of exercise MULTIPLIED by (b) the fraction of a share.

III. ADJUSTMENTS

                  3.1 INTRODUCTION. The number of Warrant Shares and the
Exercise Price of this Warrant shall be subject to adjustment from time to time
as set forth in this ARTICLE III. The Company shall give the Warrantholder
notice of any event described below which requires an adjustment pursuant to
this ARTICLE III.

                  3.2 ADJUSTMENT OF EXERCISE PRICE AND WARRANT SHARES FOR STOCK
DIVIDENDS, SUBDIVISIONS AND COMBINATIONS. If at any time during the Exercise
Period the Company shall: (a) declare a dividend payable in, or other
distribution to all holders of Outstanding shares of Common Stock of, Common
Stock; (b) subdivide or split its Outstanding shares of Common Stock into a
larger number of shares of Common Stock; or (c) combine or reclassify its
Outstanding shares of Common Stock into a smaller number of shares of Common
Stock, then: (i) the number of Warrant Shares for which this Warrant is
exercisable upon the occurrence of any such event shall be adjusted to equal the
product of (A) the number of such Warrant Shares without giving effect to such
event MULTIPLIED by (B) a fraction, the numerator of which is the number of
Outstanding shares of Common Stock after giving effect to such event and the
denominator of which is the number of Outstanding shares of Common Stock without
giving effect to such event; and (ii) the Exercise Price shall be adjusted to
equal the product of (A) the Exercise Price without giving effect to such
adjustment MULTIPLIED by (B) a fraction, the numerator of which is the number of
Warrant Shares without giving effect to such event and the denominator of which
is the number of Warrant Shares after giving effect to such event.

                  3.3 ADJUSTMENT OF EXERCISE PRICE AND WARRANT SHARES UPON
CERTAIN DISTRIBUTIONS. If, at any time during the Exercise Period, the Company
shall distribute to all holders of shares of Common Stock cash, evidences of
indebtedness of the Company or another issuer, securities of

                                       4

<Page>

the Company or another issuer, or other assets or rights or warrants to
subscribe for or purchase securities of the Company, in each case excluding
distributions that result in adjustment pursuant to SECTION 3.2 (the
"DISTRIBUTED ITEMS"), then the Exercise Price shall be adjusted according to the
following formula:

<Table>
<S>               <C>
Exercise Price =  Exercise Price x (Fair Market Value of a Warrant Share - FMV of Distributed Items)
                  ----------------------------------------------------------------------------------
                                       Fair Market Value of a Warrant Share
</Table>

                  For purposes of this SECTION 3.3, the term "FMV OF DISTRIBUTED
ITEMS" shall mean the fair market value of the Distributed Items to which the
holder of one share of Common Stock would be entitled to receive in such
distribution, as determined by the Board of Directors in good faith exercising
its fiduciary duties. Upon the occurrence of an adjustment of the Exercise Price
pursuant to this SECTION 3.3, the number of Warrant Shares shall be adjusted
according to the following formula:

     Warrant Shares =  Warrant Shares x Exercise Price (without adjustment)
                       ----------------------------------------------------
                           Exercise Price (giving effect to adjustment)

                  3.4 WHEN ADJUSTMENTS ARE TO BE MADE. Adjustments pursuant to
this ARTICLE III shall be made whenever and as often as any event necessitating
an adjustment shall occur, except that any such adjustment may be postponed
until the earlier of: (a) three (3) years following the date of such event; or
(b) the date of exercise of this Warrant, if such adjustment either by itself or
together with other such adjustments not previously made would add or subtract
less than one percent (1%) of the number of Warrant Shares for which this
Warrant is exercisable immediately prior to the making of such adjustment. Any
such postponed adjustment shall be carried forward and made on the earliest of:
(x) the date of exercise of this Warrant; (y) the date on which such postponed
adjustment, together with any other required but unmade adjustments, would
result in an adjustment of sufficient magnitude to be required to be made
pursuant to this SECTION 3.4; or (z) three (3) years following the date of the
event necessitating the adjustment. For the purpose of this SECTION 3.4, an
event necessitating an adjustment shall be deemed to have occurred at the close
of business on the date of its occurrence.

IV. NOTICES TO THE WARRANTHOLDER

                  4.1 NOTICE OF CAPITAL EVENT. If, at any time during the
Exercise Period, there shall be proposed a Capital Event, then the Company shall
promptly deliver to the Warrantholder a certificate executed by an officer of
the Company: (a) setting forth, in reasonable detail, the circumstances
surrounding the Capital Event; (b) the time, if any such time is to be fixed, as
of which the holders of Common Stock shall be entitled to exchange their shares
of Common Stock for securities or other property deliverable upon such Capital
Event; and (c) describing the number and kind of other shares of stock or other
securities or property for which the warrant of the Successor (as defined in
SECTION 6.1) issued to the Warrantholder in exchange for this Warrant upon such
Capital Event pursuant to SECTION 6.1 will be exercisable.

                  4.2 NOTICE OF ADJUSTMENTS. Whenever an event necessitating an
adjustment to this Warrant pursuant to ARTICLE III occurs (regardless of whether
such adjustment may be postponed pursuant to SECTION 3.4), the Company shall
promptly deliver to the Warrantholder a certificate executed by an officer of
the Company: (a) setting forth, in reasonable detail, the event necessitating
such adjustment and the method by which such adjustment was calculated; and (b)
specifying the number of Warrant Shares and the Exercise Price, in each case
giving effect to the adjustment.

                  4.3 MAINTENANCE OF OFFICERS' CERTIFICATES. The Company shall
keep at its office located at the address set forth in SECTION 11.5 copies of
all officers' certificates provided to the Warrantholder pursuant to SECTIONS

                                       5

office during normal business hours by the Warrantholder or any prospective
purchaser of this Warrant designated by the Warrantholder.

V. RESTRICTIONS ON TRANSFER

                  5.1 RESTRICTIONS ON TRANSFER. The Warrantholder, by its
acceptance of this Warrant, agrees to be bound by the provisions of this ARTICLE
V and acknowledges and confirms that this Warrant and any Warrant Shares issued
upon exercise of all or part of this Warrant have not been registered under the
Securities Act or any applicable state securities laws, and may not be sold or
transferred except in compliance with and subject to the Securities Act and such
state securities laws. Unless and until this Warrant and such Warrant Shares
have been registered under the Securities Act and such state securities laws,
the Company may require, as a condition to effecting any sale or transfer of
this Warrant or such Warrant Shares on the books of the Company, an opinion of
counsel reasonably satisfactory to the Company to the effect that an exemption
from registration under the Securities Act and such state securities laws is
available for the proposed transfer or assignment or a certification reasonably
satisfactory to the counsel of the Company in its professional determination
from the transferee that it is an accredited investor as defined under the
Securities Act and regulations promulgated thereunder; PROVIDED, HOWEVER, that
if the Warrant Shares have been held (both legally and beneficially) by the
Warrantholder for at least one (1) year and are proposed to be sold in
compliance with Rule 144 under the Securities Act, no such opinion of counsel
shall be required. Any purported sale or transfer of this Warrant and/or such
Warrant Shares shall be null and void unless made in compliance with the
conditions set forth in this ARTICLE V. Except as provided in SECTION 5.3, (a)
this Warrant and any warrant of the Company issued in exchange or replacement
for this Warrant shall be stamped or otherwise imprinted with a legend in
substantially the form set forth on the cover of this Warrant; and (b) each
stock certificate for Warrant Shares issued upon the exercise of this Warrant
and each stock certificate issued upon the transfer of any such Warrant Shares
shall be stamped or otherwise imprinted with a legend substantially to the same
effect.

                  5.2 TERMINATION OF RESTRICTIONS. The restrictions imposed by
SECTION 5.1 upon the transferability of this Warrant and the Warrant Shares
shall terminate: (a) when and so long as this Warrant or such Warrant Shares
shall have been effectively registered under the Securities Act and transferred
in compliance therewith; or (b) when the Company shall have received an opinion
of counsel reasonably satisfactory to it that this Warrant or such Warrant
Shares may be transferred without registration thereof under the Securities Act;
PROVIDED, HOWEVER, that if the Warrant or the Warrant Shares have been held
(both legally and beneficially) by the Warrantholder for at least one (1) year
and are proposed to be sold in compliance with Rule 144 under the Securities
Act, no such opinion of counsel shall be required. Whenever the legend
requirements imposed by SECTION 5.1 shall terminate as to this Warrant or any
Warrant Shares, the holder of this Warrant or such Warrant Shares shall be
entitled to receive from the Company, at the Company's expense, a new warrant or
a new stock certificate representing such Warrant Shares, as the case may be,
not bearing the restrictive legend described in SECTION 5.1.

                  5.3 COMPLIANCE WITH SECURITIES LAWS. The Warrantholder, by
acceptance hereof, represents to the Company that this Warrant and any Warrant
Shares purchased upon exercise of this Warrant are being acquired solely for the
Warrantholder's own account and not as a nominee for any other party, and for
investment, and that the Warrantholder will not offer, sell or otherwise dispose
of this Warrant or any such Warrant Shares except under circumstances that will
not result in a violation of the Securities Act or any applicable state
securities laws. Upon exercise of all or part of this Warrant, the Warrantholder
shall, if requested by the Company, confirm in writing, in a form reasonably
satisfactory to counsel of the Company, the foregoing representations and other
representations regarding the Warrantholder's status as an accredited or
sophisticated investor (as defined under Rules 501(a) and

                                       6

<Page>

506(b)(2)(ii), respectively, of Regulation D under the Securities Act) as may be
reasonably requested by the Company.

                  5.4 TRANSFER PROCEDURE. Subject to compliance with the other
provisions of this ARTICLE V, transfer of this Warrant, in whole or in part,
shall occur upon surrender of this Warrant at the principal office of the
Company at the address set forth in SECTION 10.5, together with a duly executed
written assignment of this Warrant and funds sufficient to pay any transfer
taxes payable upon the making of such transfer and, if required, an opinion of
counsel reasonably acceptable to counsel of the Company in its professional
determination concerning the compliance of such transfer with the Securities Act
and applicable state securities laws. Upon receipt of such items, the Company
shall execute and deliver a new warrant or warrants in the name of the assignee
or assignees and in the denomination(s) specified in such instrument of
assignment, and shall issue to the assignor a new warrant evidencing the portion
of this Warrant not so assigned, and this Warrant shall promptly be cancelled.

                  5.5 MAINTENANCE OF TRANSFER BOOKS. The Company agrees to
maintain, at the principal office of the Company at the address set forth in
SECTION 10.5, books or records for the registration and the registration of
transfer of this Warrant or any warrant of the Company issued in exchange for
this Warrant.

VI. CAPITAL EVENT

                  6.1 ISSUANCE OF NEW WARRANT IN SUCCESSOR UPON CAPITAL EVENT.
Upon the consummation of any Capital Event, the successor or acquiring Person
(the "SUCCESSOR") to or in such Capital Event shall issue to the Warrantholder a
new warrant of the Successor which shall include all material terms of this
Warrant, including without limitation the provisions of Section 2.4 regarding
vesting and exercise, except that such warrant shall provide for the purchase
(upon satisfaction of the relevant vesting criteria under Section 2.4), at the
Exercise Price per share, instead of the number of shares of Common Stock
issuable hereunder, of the kind and amount of shares of common stock or other
securities or cash or other property of the Successor that would be received by
a holder of such number of shares of Common Stock in such Capital Event.

                  6.2 SUCCESSIVE CAPITAL EVENTS. The provisions of this
ARTICLE VI shall apply to successive Capital Events.

VII. NECESSARY ACTIONS

                  The Company will: (a) use its commercially reasonable efforts
to obtain all such authorizations, approvals, exemptions or consents from any
Governmental Authority having jurisdiction thereof as may be necessary to enable
the Company to perform its obligations under this Warrant (including, without
limitation, making all necessary filings with such Governmental Authorities);
(b) take all necessary steps (including, without limitation, making appropriate
amendments to its certificate of incorporation) to ensure that the Company has
authorized a sufficient number of authorized but unissued shares of its common
stock to provide for the issuance of the Warrant Shares; (c) reserve from such
authorized but unissued shares of common stock a sufficient number of shares to
provide for the issuance of the Warrant Shares upon the exercise of this
Warrant; and (d) take all actions as may be necessary or appropriate to ensure
that the Company may validly and legally issue fully paid and non-assessable
shares of Common Stock upon the exercise of this Warrant that are not subject to
any preemptive rights and are free from all taxes, liens, security interests,
charges, and other encumbrances with respect to the issuance thereof, other than
taxes in respect of any transfer occurring contemporaneously with such issuance.

Warrantholder and each holder of Warrant Shares in supplying such information as
may be reasonably necessary for such holders to complete and file any
information reporting forms presently or hereafter required by the Securities
Exchange Commission and any state securities agency as a condition to the
availability of an exemption under the Securities Act and any applicable state
securities law for the sale of this Warrant or any Warrant Shares.

                  8.2 INFORMATION. During the Exercise Period, the Company shall
provide to the Warrantholder copies of all reports, filings and financial

                  On receipt of evidence reasonably satisfactory to the Company
of the loss, theft, destruction or mutilation of this Warrant and (a) in the
case of loss, theft or destruction, on delivery of an indemnity agreement
reasonably satisfactory in form and substance to the Company; or (b) in the case
of mutilation, on surrender and cancellation of this Warrant, the Company at its
expense shall execute and deliver, in lieu of this Warrant, a new warrant of
like tenor and amount.

                  10.2 NONWAIVER. No course of dealing or any delay or failure

Warrant will be interpreted in such manner as to be effective and valid under

jurisdiction. In such event, this Warrant will be reformed, construed and
enforced in such jurisdiction as if such invalid, illegal or unenforceable
