          ------------------
P.M., New York time, on the Expiration Date, Holder may exercise this Warrant,
on any Business Day, for all or any part of the number of shares of Common Stock
purchasable hereunder.

          In order to exercise this Warrant, in whole or in part, Holder shall
deliver to Company at its principal office at 8000 Regency Parkway, Cary, North
Carolina 27511 or at the office or agency designated by Company pursuant to
Section 12, (i) a written notice of Holder's election to exercise this Warrant,
which notice shall specify the number of shares of Common Stock to be purchased,
(ii) payment of the Warrant Price and (iii) this Warrant.  Such notice shall be
substantially in the form of the subscription form appearing at the end of this
Warrant as Exhibit A, duly executed by Holder or its agent or attorney.  Upon
           ---------
receipt thereof, Company shall, as promptly as practicable, and in any event
within ten (10) Business Days thereafter, execute or cause to be executed and
deliver or cause to be delivered to Holder a certificate or certificates
representing the aggregate number of full shares of Common Stock issuable upon
such exercise, together with cash in lieu of any fraction of a share, as
hereinafter provided.  The stock certificate or certificates so delivered shall
be, to the extent possible, in such denomination or denominations as such Holder
shall request in the notice and shall be registered in the name of Holder or,
subject to Section 9, such other name as shall be designated in the notice.
This Warrant shall be deemed to have been exercised and such certificate or
certificates shall be deemed to have been issued, and Holder or any other Person
so designated to be named therein shall be deemed to have become a holder of
record of such shares for all purposes, as of the date the notice, together with
the cash or check or checks and this Warrant, is received by Company as
described above and all taxes required to be paid by Holder, if any, pursuant to
Section 2.2 prior to the issuance of such shares have been paid.  If this
Warrant shall have been exercised in part, Company shall, at the time of
delivery of the certificate or certificates representing Warrant Stock, deliver
to Holder a new Warrant evidencing the rights of Holder to purchase the
unpurchased shares of Common Stock called for by this Warrant, which new Warrant
shall in all other respects be identical with this Warrant, or, at the request
of Holder, appropriate notation may be made on this Warrant and the same
returned to Holder.  Notwithstanding any provision herein to the contrary,
Company shall not be required to register shares in the name of any Person who
acquired this Warrant (or part hereof) or any Warrant Stock otherwise than in
accordance with this Warrant.

          Payment of the Warrant Price shall be made at the option of the Holder
by (i) wire transfer to an account designated by Company, (ii) certified or
official bank check, and/or (iii) by the Holder's surrender to Company of that
number of shares of Warrant Stock (or the right to receive such number of
shares) or shares of Common Stock having an aggregate Current Market Price equal
to or greater than the Current Warrant Price for all shares then being purchased
(including those being surrendered), or (iv) any

                                       4
<PAGE>

combination thereof, duly endorsed by or accompanied by appropriate instruments
of transfer duly executed by Holder or by Holder's attorney duly authorized in
writing.

     2.2. Payment of Taxes.  All shares of Common Stock issuable upon the
          ----------------
exercise of this Warrant pursuant to the terms hereof shall be validly issued,
fully paid and nonassessable and without any preemptive rights.  Company shall
pay all expenses in connection with, and all taxes and other governmental
charges that may be imposed with respect to, the issue or delivery thereof,
unless such tax or charge is imposed by law upon Holder, in which case such
taxes or charges shall be paid by Holder.  Holder or its transferee shall pay
any transfer tax due and payable in respect of a transfer of this Warrant or the
Warrant Stock to a party other than Holder.

     2.3. Fractional Shares.  Company shall not be required to issue a
          -----------------
fractional share of Common Stock upon exercise of any Warrant.  As to any
fraction of a share which the Holder of one or more Warrants, the rights under
which are exercised in the same transaction, would otherwise be entitled to
purchase upon such exercise, Company shall pay a cash adjustment in respect of
such final fraction in an amount equal to the same fraction of (x) the Current
Market Price per share of Common Stock on the date of exercise, so long as there
continues to be a public market for the Common Stock, or (y) in the event there
is no public market for the Common Stock, the fair market value thereof as
reasonably determined by the Board of Directors of Company.

     2.4. Continued Validity.  A holder of shares of Common Stock issued upon
          ------------------
the exercise of this Warrant, in whole or in part (other than a holder who
acquires such shares after the same have been publicly sold pursuant to a
Registration Statement under the Securities Act or sold pursuant to Rule 144
thereunder), shall continue to be entitled to all rights, and subject to all
obligations, to which it would have been entitled or obligated, as applicable,
as Holder under Sections 9, 10 and 15 of this Warrant.  Company will, at the
time of each exercise of this Warrant, in whole or in part, upon the request of
the holder of the shares of Common Stock issued upon such exercise hereof,
acknowledge in writing, in form reasonably satisfactory to such holder, its
continuing obligation to afford to such holder all such rights; provided,
                                                                --------
however, that if such holder shall fail to make any such request, such failure
-------
shall not affect the continuing obligation of Company to afford to such holder
all such rights.

3. TRANSFER, DIVISION AND COMBINATION
   ----------------------------------

     3.1. Transfer.  Subject to compliance with Section 9, transfer of this
          --------
Warrant and all rights hereunder, in whole or in part, shall be registered on
the books of Company to be maintained for such purpose, upon surrender of this
Warrant at the principal office of Company referred to in Section 2.1 or the
office or agency designated by Company pursuant to Section 12, together with a
written assignment of this Warrant substantially in the form of Exhibit B hereto
                                                                ---------
duly executed by Holder or its agent or attorney.  Upon such surrender, Company
shall, subject to Section 9, execute and deliver a new Warrant or Warrants in
the name of the assignee or assignees and in the denomination 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
<PAGE>

A Warrant, if properly assigned in compliance with Section 9, may be exercised
by a new Holder for the purchase of shares of Common Stock without having a new
Warrant issued.

     3.2. Division and Combination.  Subject to Section 9, this Warrant may be
          ------------------------
divided or combined with other Warrants upon presentation hereof at the
aforesaid office or agency of Company, together with a written notice specifying
the names and denominations in which new Warrants are to be issued, signed by
Holder or its agent or attorney.  Subject to compliance with Section 3.1 and
with Section 9, as to any transfer which may be involved in such division or
combination, Company shall execute and deliver a new Warrant or Warrants in
exchange for the Warrant or Warrants to be divided or combined in accordance
with such notice.

     3.3. Expenses.  Company shall prepare, issue and deliver at its own expense
          --------
the new Warrant or Warrants to be delivered under this Section 3.

     3.4. Maintenance of Books.  Company agrees to maintain, at its aforesaid
          --------------------
office or agency, books for the registration and the registration of transfer of
the Warrants.

4. ADJUSTMENTS
   -----------

          The number of shares of Common Stock for which this Warrant is
exercisable, or 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.  Company shall give each Holder notice of any event described
below which requires an adjustment pursuant to this Section 4 at the time of
such event.

     4.1. Stock Dividends, Subdivisions and Combinations.  If at any time
          ----------------------------------------------
Company shall:

          (a)  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,

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

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

then (i) 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 (ii) the Current Warrant Price
shall be adjusted to equal (A) the Current Warrant Price multiplied by the
number of shares of Common Stock for which this Warrant is

                                       6
<PAGE>

exercisable immediately prior to the adjustment divided by (B) the number of
shares for which this Warrant is exercisable immediately after such adjustment.

     4.2. Certain Other Distributions.  If at any time the Company 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:

          (a)  cash,

          (b)  any evidences of its indebtedness, any shares of its stock or any
other securities or property of any nature whatsoever (other than cash,
Convertible Securities or Additional Shares of Common Stock), or

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

then (i) 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 by a fraction (A) the numerator of which shall be the Current Market
Price per share of Common Stock at the date of taking such record and (B) the
denominator of which shall be such Current Market Price per share of Common
Stock 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 Company) of any and all such evidences of indebtedness, shares
of stock, other securities or property or warrants or other subscription or
purchase rights so distributable, and (ii) the Current Warrant Price shall be
adjusted to equal (A) the Current Warrant Price 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 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 Company to the holders of
its Common Stock of such shares of such other class of stock within the meaning
of this Section 4.2 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 4.1.

     4.3. 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
Current Warrant Price provided for in this Section 4:

                                       7
<PAGE>

          (a)  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 Common Stock, as provided for in Section 4.1) 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 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.

          (b)  Fractional Interests. In computing adjustments under this Section
               --------------------
4, fractional interests in Common Stock shall be taken into account to the
nearest 1/10th of a share.

          (c)  When Adjustment Not Required. If Company shall take a record of
               ----------------------------
the holders of its Common Stock for the purpose of entitling them to receive a
dividend or distribution and shall, thereafter and before the distribution to
stockholders thereof, legally abandon its plan to pay or deliver such dividend
or distribution, then thereafter no adjustment shall be required by reason of
the taking of such record and any such adjustment previously made in respect
thereof shall be rescinded and annulled.

          (d)  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 Holder exercises this Warrant, any Additional
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 Holder by Company to be issued to
Holder upon and to the extent that the event actually takes place, upon payment
of the then 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 Company and
escrowed property returned.

     4.4. Reorganization, Reclassification, Merger, Consolidation or Disposition
          ----------------------------------------------------------------------
of Assets.  In case Company shall reorganize its capital, reclassify its capital
---------
stock, consolidate or merge with or into another corporation or other business
entity (where Company is not the surviving corporation or where there is a
change in or distribution with respect to the Common Stock of Company), or sell,
transfer or otherwise dispose of all or substantially all its property, assets
or business to another corporation or other business entity and, pursuant to the
terms of such reorganization, reclassification, merger, consolidation or
disposition of assets, shares of common stock of the successor or

                                       8
<PAGE>

acquiring corporation, or any cash, shares of stock or other securities or
property of any nature whatsoever (including warrants or other subscription or
purchase rights) in addition to or in lieu of common stock of the successor or
acquiring corporation ("Other Property"), are to be received by or distributed
                        --------------
to the holders of Common Stock of Company, then each Holder shall have the right
thereafter to receive, upon exercise of such Warrant, the number of shares of
common stock of the successor or acquiring corporation or of Company, if it is
the surviving corporation, and Other Property receivable upon or as a result of
such reorganization, reclassification, merger, consolidation or disposition of
assets by a holder of the number of shares of Common Stock for which this
Warrant is exercisable immediately prior to such event. In case of any such
reorganization, reclassification, merger, consolidation or disposition of
assets, the successor or acquiring corporation (if other than Company) or other
business entity shall expressly assume the due and punctual observance and
performance of each and every covenant and condition of this Warrant to be
performed and observed by Company and all the obligations and liabilities
hereunder, subject to such modifications as may be deemed appropriate (as
determined by resolution of the Board of Directors of Company) in order to
provide for adjustments of shares of Common Stock for which this Warrant is
exercisable which shall be as nearly equivalent as practicable to the
adjustments provided for in this Section 4. For purposes of this Section 4.4,
"common stock of the successor or acquiring corporation" shall include stock of
such corporation of any class which is not preferred as to dividends or assets
over any other class of stock of such corporation and which is not subject to
redemption and shall also include any evidences of indebtedness, shares of stock
or other securities which are convertible into or exchangeable for any such
stock, either immediately or upon the arrival of a specified date or the
happening of a specified event and any warrants or other rights to subscribe for
or purchase any such stock. The foregoing provisions of this Section 4.4 shall
similarly apply to successive reorganizations, reclassifications, mergers,
consolidations or disposition of assets.

     5.2. Notice of Corporate Action.  If at any time
          --------------------------

          (a)  Company shall take a record of the holders of its Common Stock
for the purpose of entitling them to receive a dividend (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
Company) or other distribution, or any right to subscribe for or purchase any
evidences of its indebtedness, any shares of stock of any class or any other
securities or property, or to receive any other right, or

          (b)  there shall be any capital reorganization of Company, any
reclassification or recapitalization of the capital stock of Company or any
consolidation or merger of Company with, or any sale, transfer or other
disposition of all or substantially all the property, assets or business of
Company to, another corporation, or

          (c)  there shall be a voluntary or involuntary dissolution,
liquidation or winding up of Company;

then, in any one or more of such cases, Company shall give to Holder (i) at
least ten (10) days' prior written notice of the date on which a record date
shall be selected for such dividend, distribution or right or for determining
rights to vote in respect of any such reorganization, reclassification, merger,
consolidation, sale, transfer, disposition, dissolution, liquidation or winding
up, and (ii) in the case of any such reorganization, reclassification, merger,
consolidation, sale, transfer, disposition, dissolution, liquidation or winding
up, at least ten (10) days' prior written notice of the date when the same shall
take place.  Such notice in accordance with the foregoing clause also shall
specify (A) the date on which any such record is to be taken for the purpose of
such dividend, distribution or right, the date on which the holders of Common
Stock shall be entitled to any such dividend, distribution or right, and the
amount and character thereof, and (B) the date on which any such reorganization,
reclassification, merger, consolidation, sale, transfer, disposition,
dissolution, liquidation or winding up is to take place and 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 reorganization, reclassification, merger,
consolidation, sale, transfer, disposition, dissolution, liquidation or winding
up.  Each such written notice shall be sufficiently given if addressed to Holder
at the last address of Holder appearing on the books of Company and delivered in
accordance with Section 15.2.

6.  NO IMPAIRMENT
    -------------

          Company shall not by any action, including, without limitation,
amending 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

                                       10
<PAGE>

in the taking of all such actions as may be necessary or appropriate to protect
the rights of Holder against impairment. Without limiting the generality of the
foregoing, Company will (a) not increase the par value of any shares of Common
Stock receivable upon the exercise of this Warrant above the amount payable
therefor upon such exercise immediately prior to such increase in par value, (b)
take all such action as may be necessary or appropriate in order that Company
may validly and legally issue fully paid and nonassessable shares of Common
Stock upon the exercise of this Warrant, and (c) use its best efforts to obtain
all such authorizations, exemptions or consents from any public regulatory body
having jurisdiction thereof as may be necessary to enable Company to perform its
obligations under this Warrant.

          Upon the reasonable request of Holder, Company will at any time during
the period this Warrant is outstanding acknowledge in writing, in form
reasonably satisfactory to Holder, the continuing validity of this Warrant and
the obligations of Company hereunder.

7.  RESERVATION AND AUTHORIZATION OF COMMON STOCK; REGISTRATION WITH OR APPROVAL
    ----------------------------------------------------------------------------
OF ANY GOVERNMENTAL AUTHORITY
-----------------------------

          From and after the Closing Date, Company shall at all times reserve
and keep available for issue upon the exercise of Warrants such number of its
authorized but unissued shares of Common Stock as will be sufficient to permit
the exercise in full of all outstanding Warrants.  All shares of Common Stock
which shall be so issuable, when issued upon exercise of any Warrant and payment
therefor in accordance with the terms of such Warrant, shall be duly and validly
issued and fully paid and nonassessable, and not subject to preemptive rights.

          Before taking any action which would cause an adjustment reducing the
Current Warrant Price below the then par value, if any, of the shares of Common
Stock issuable upon exercise of the Warrants, Company shall take any corporate
action which may be necessary in order that Company may validly and legally
issue fully paid and non-assessable shares of such Common Stock at such adjusted
Current Warrant Price.

          Before taking any action which would result in an adjustment in the
number of shares of Common Stock for which this Warrant is exercisable or in the
Current Warrant Price, Company shall obtain all such authorizations or
exemptions thereof, or consents thereto, as may be necessary from any public
regulatory body or bodies having jurisdiction thereof.

          If any shares of Common Stock required to be reserved for issuance
upon exercise of Warrants require registration or qualification with any
governmental authority or other governmental approval or filing under any
federal or state law (otherwise than as provided in Section 9) before such
shares may be so issued, Company will in good faith and as expeditiously as
possible and at its expense endeavor to cause such shares to be duly registered.

8.  TAKING OF RECORD; STOCK AND WARRANT TRANSFER BOOKS
    --------------------------------------------------

          In the case of all dividends or other distributions by Company to the
holders of its Common Stock with respect to which any provision of Section 4
refers to the taking of a record of such holders, Company will in each such case
take such a record and will take such record as of the close of business on a
Business Day.  Company will not at any time, except upon dissolution,
liquidation or winding up of Company, close its stock transfer books or Warrant
transfer books so as to result in preventing or delaying the exercise or
transfer of any Warrant.

9.  RESTRICTIONS ON TRANSFERABILITY
    -------------------------------

          The Warrants and the Warrant Stock shall not be transferred,
hypothecated or assigned before satisfaction of the conditions specified in this
Section 9, which conditions are intended to ensure compliance with the
provisions of the Securities Act with respect to the Transfer of any Warrant or
any Warrant Stock; provided, however, that any Holder may Transfer the Warrants
                   --------  -------
and/or any Warrant Stock to an "affiliate", as that term is defined for purposes
of Rule 145 of the Rules and Regulations of the Commission under the Securities
Act of 1933, as amended.  Holder, by acceptance of this Warrant, agrees to be
bound by the provisions of this Section 9.

                    "The shares represented by this certificate
          have not been registered under the Securities Act of
          1933, as amended, and are subject to the conditions
          specified in a certain Warrant dated ____________,
          2000, originally issued by [Level 8 Systems, Inc.]. No
          transfer of the shares represented by this certificate
          shall be valid or effective until such conditions have
          been fulfilled. A copy of the form of said Warrant is
          on file with the Secretary of [Parent]. The holder of
          this certificate, by acceptance of this certificate,
          agrees to be bound by the provisions of such Warrant."

          (a)  Except as otherwise provided in this Section 9, each Warrant
shall be stamped or otherwise imprinted with a legend in substantially the
following form:

                    "This Warrant and the securities represented
          hereby have not been registered under the Securities
          Act of 1933, as amended, and shall not be transferred
          in violation of such Act, the rules and regulations
          thereunder or the provisions of this Warrant."

     9.2. Notice of Proposed Transfers.  Prior to or promptly following any
          ----------------------------
Transfer of any Warrants or any shares of Restricted Common stock, the holder of
such Warrants or Restricted Common Stock shall give written notice (a "Transfer
                                                                       --------
Notice") to Company of such Transfer.  Each certificate, if any, evidencing such
------
shares of Restricted Common Stock issued upon such Transfer shall bear the
restrictive legend set forth in Section 9.1(a), and each Warrant issued upon
such Transfer shall bear the restrictive legend set forth in Section 9.1(b),
unless (a) such shares of Common Stock have been effectively registered under
the Securities Act or (b) in the opinion of counsel to such holder which is
reasonably acceptable to Company such legend is not required in order to ensure
compliance with the Securities Act.

     9.3. Termination of Restrictions.  Notwithstanding the foregoing provisions
          ---------------------------
of Section 9, the restrictions imposed by this Section upon the transferability
of the Warrants, the Warrant Stock and the Restricted Common Stock (or Common
Stock issuable upon the exercise of the Warrants) and the legend requirements of
Section 9.1 shall terminate as to any particular Warrant or share of Warrant
Stock or Restricted Common Stock (or Common Stock issuable upon the exercise of
the Warrants) (a) when and so long as such security shall have been effectively
registered under the Securities Act and disposed of pursuant thereto or (b) when
such shares may be sold pursuant to Rule 144 of the Securities Act or otherwise
transferred without registration thereof under the Securities Act and Company
shall have received an opinion of counsel reasonably satisfactory to it,
including an opinion of in-house counsel to the Holder, that such shares may be
transferred without registration thereof under the Securities Act.  Whenever the
restrictions imposed by Section 9 shall terminate as to this Warrant, as
hereinabove provided, the Holder hereof shall be entitled to receive from
Company, at the expense of Company, a new Warrant bearing the following legend
in place of the restrictive legend set forth hereon:

                    "THE RESTRICTIONS ON TRANSFERABILITY OF THE
          WITHIN WARRANT CONTAINED IN SECTION 9 HEREOF TERMINATED
          ON ________, 20__, AND ARE OF NO FURTHER FORCE AND
          EFFECT."

All Warrants issued upon registration of transfer, division or combination of,
or in substitution for, any Warrant or Warrants entitled to bear such legend
shall have a similar legend endorsed thereon.  Whenever the restrictions imposed
by this Section shall terminate as to any share of Restricted Common Stock, as
hereinabove provided, the holder thereof shall be entitled to receive from
Company, at Company's expense, a new certificate representing such Common Stock
not bearing the restrictive legend set forth in Section 9.1(a).

     9.4. Additional Listing.  The Company will, at its expense, list thereon,
          ------------------
maintain and, when necessary, increase such listing of, all shares of Common
Stock issued or, to the extent permissible under the applicable securities
exchange rules, issuable upon the exercise of this Warrant so long as any shares
of Common Stock shall be listed on NASDAQ or any national securities exchange
during the Exercise Period.

10.  SUPPLYING INFORMATION
     ---------------------

          Company shall cooperate with each Holder of a Warrant and each holder
of Restricted Common Stock in supplying such information as may be reasonably
necessary for such holder to complete and file any information reporting forms
presently or hereafter required by the Commission as a condition to the
availability of an exemption from the Securities Act for the sale of any Warrant
or Restricted Common Stock.

11.  LOSS OR MUTILATION
     ------------------

          Upon receipt by Company from any Holder of evidence reasonably
satisfactory to it of the ownership of and the loss, theft, destruction or
mutilation of this Warrant and indemnity reasonably satisfactory to it, and in
case of mutilation upon surrender and cancellation hereof, Company will execute
and deliver in lieu hereof a new Warrant of like tenor to such Holder; provided,
                                                                       --------
in the case of mutilation, no indemnity shall be required if this Warrant in
identifiable form is surrendered to Company for cancellation.

12.  OFFICE OF COMPANY
     -----------------

          As long as any of the Warrants remain outstanding, Company shall
maintain an office or agency (which may be the principal executive offices of
Company) where the Warrants may be presented for exercise, registration of
transfer, division or combination as provided in this Warrant.

13.  FILINGS

pursuant to Section 12 of the Exchange Act, Company will file on or before the
required date all regular or periodic reports (pursuant to the Exchange Act)
required to be filed with the Commission pursuant to the Exchange Act and will
deliver to Holder promptly upon their becoming available (unless such reports
are available through the Commission's EDGAR system) one copy of each report,

each regular or periodic report (pursuant to the Exchange Act) and any

the Holder to any rights as a stockholder of Company, including, without
limitation, the right to vote, to receive dividends and other distributions or
to receive notice of or attend meetings of stockholders or any other proceedings
of Company unless and to the extent exercised for shares of Common Stock in
accordance with the terms hereof.  No provision hereof, in the absence of
affirmative action by Holder to exercise its rights to purchase shares of Common
Stock hereunder, and no enumeration herein of the rights or

                                       14
<PAGE>

privileges of Holder hereof, shall give rise to any liability of such Holder for
the purchase price of any Common Stock or as a stockholder of Company, whether
such liability is asserted by Company or by creditors of Company.

15. MISCELLANEOUS
    -------------

     15.1. Nonwaiver and Expenses.  No course of dealing or any delay or failure
           ----------------------
to exercise any right hereunder on the part of Holder shall operate as a waiver
of such right or otherwise prejudice Holder's rights, powers or remedies.  If
Company fails to make, when due, any payments provided for hereunder, or fails
to comply with any other provision of this Warrant, Company shall pay to Holder
such amounts as shall be sufficient to cover any costs and expenses including,

proceedings, incurred by Holder in collecting any amounts due pursuant hereto or
in otherwise enforcing any of its rights, powers or remedies hereunder.

     15.2. Notice Generally.  Any notice, demand, request, consent, approval,
           ----------------
declaration, delivery or other communication hereunder to be made pursuant to

being entitled to exercise all rights granted by law, including recovery of

<PAGE>

be entitled to specific performance of its rights under Section 9 of this
Warrant. Company agrees that monetary damages would not be adequate compensation
for any loss incurred by reason of a breach by it of the provisions of Section 9
of this Warrant and hereby agrees to waive the defense in any action for
specific performance that a remedy at law would be adequate.

     15.4. Successors and Assigns. Subject to the provisions of Sections 3.1 and
           ----------------------
9, this Warrant and the rights evidenced hereby shall inure to the benefit of

therein) without the prior written consent of the Holder thereof.

     15.6. Severability. Wherever possible, each provision of this Warrant shall
           ------------
be interpreted in such manner as to be effective and valid under applicable law,
but if any provision of this Warrant shall be prohibited by or invalid under
applicable law, such provision shall be ineffective to the extent of such
prohibition or invalidity, without invalidating the remainder of such provision
or the remaining provisions of this Warrant.

     15.7. Headings.  The headings used in this Warrant are for the convenience
           --------
of reference only and shall not, for any purpose, be deemed a part of this
Warrant.

     15.8. Governing Law.  This Warrant shall be governed by the laws of the
           -------------

of laws.
