P.M., New York City time, on the Expiration Date, Holder may exercise this
Warrant, on any Business Day, in increments of 10,000 shares of Common Stock
purchasable hereunder.

         In order to exercise this Warrant, in whole or in part, Holder shall
deliver to the Company at its principal office at 410 Park Avenue, Suite 830 New
York, New York 10022, or at the office or agency designated by the 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 in cash or by wire transfer or
cashier's check drawn on a United States bank 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 of the items referred to in clauses (i), (ii) and (iii)
above, the 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 Holder shall request in the
notice
<PAGE>   5
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 the 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, the Company shall, at the time of delivery of the certificate
or certificates representing Warrant Shares, 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, the Company shall not be
required to register shares in the name of any Person who acquired this Warrant
(or part hereof) or any Warrant Shares otherwise than in accordance with this
Warrant.

         2.2 Payment of Taxes and Charges. 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. The
Company shall pay all expenses in connection with, and all taxes and other
governmental charges (excluding income and related taxes) 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. The Company shall not be required, however, to pay any tax or other
charge imposed in connection with any transfer involved in the issue of any
certificate for shares of Common Stock issuable upon exercise of this Warrant in
any name other than that of Holder, 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 satisfaction of the
Company that no such tax or other charge is due.

         2.3 Fractional Shares. The 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 Holder would otherwise be entitled to purchase upon
such exercise, the Company shall pay a cash adjustment in respect of such final
fraction in an amount equal to the same fraction of the Market Price per share
of Common Stock as of the Initial Funding Date.

         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 with respect to such shares to all
rights to which it would have been entitled as Holder under Sections 9, 10 and
14 of this Warrant. The Company will, at the time of exercise of this Warrant,
in whole or in part, upon the request of Holder, acknowledge in writing, in form
reasonably satisfactory to Holder, its continuing obligation to afford Holder
all such rights; provided, however, that if Holder shall fail to make any such
request, such failure shall not affect the continuing obligation of the Company
to afford to Holder all such rights.

3.       TRANSFER, DIVISION AND COMBINATION

         3.1 Transfer. Subject to compliance with the Securities Purchase
Agreement and this Section 3.1 and Section 9 herein, transfer of this Warrant
and all rights hereunder, in whole or in part, shall be registered on the books
of the Company to be maintained for such purpose, upon surrender of this Warrant
at the principal office of the Company referred to in Section 2.1 or the office
or agency designated by the 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 and funds sufficient to pay any
transfer taxes payable upon the making of such transfer. Upon such surrender
and, if required, such payment, the 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. 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 3.1 and 9, this
Warrant may be divided or combined with other Warrants upon presentation hereof
at the aforesaid office or agency of the 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, the 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. The Company shall prepare, issue and deliver at its own
expense (other than transfer taxes) the new Warrant or Warrants under this
Section 3.

         3.4 Maintenance of Books. The 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. The Company shall give 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 the
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,
<PAGE>   7
                  (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 multi-plied 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.

         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 Holder shall be entitled to receive such dividend or distribution as if
Holder had exercised this Warrant. 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 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:
<PAGE>   8
                  (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. 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 the Company 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
         stock-holders 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 of
         such record and any such adjustment previously made in respect thereof
         shall be rescinded and annulled.

                  (d) Challenge to Good Faith Determination. Whenever the Board
         of Directors of the Company shall be required to make a determination
         in good faith of the fair value of any item under this Section 4, such
         determination may be challenged in good faith by the Holder, and any
         dispute shall be resolved by an investment banking firm of recognized
         national standing selected by the Company and reasonably acceptable to
         the Holder.

         4.4 Reorganization, Reclassification, Merger, Consolidation or
Disposition of Assets. In case the Company shall reorganize its capital,
reclassify its capital stock, consolidate or merge with or into another Person
(where the Company is not the survivor or where there is a change in or
distribution with respect to the Common Stock of the Company), or sell, convey,
transfer or otherwise dispose of all or substantially all its property, assets
or business to another Person, or effectuate a transaction or series of related
transactions in which more than 50% of the voting power of the Company is
disposed of (each, a "Fundamental Corporate Change") and, pursuant to the terms
of such Fundamental Corporate Change, shares of common stock of the successor or
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 the Company, then Holder shall have the right
thereafter to receive, upon exercise of the Warrant, such number of shares of
common stock of the successor or acquiring corporation or of the Company, if it
is the surviving corporation, and Other Property as is receivable upon or as a
result of such Fundamental Corporate Change by a holder of the number of shares
of Common Stock for which this Warrant is exercisable immediately prior to such
Fundamental Corporate Change. In case of any such Fundamental Corporate Change,
the successor or acquiring corporation (if other than the Company) 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 the
Company and all the obligations and liabilities hereunder, subject to such
modifications as may be deemed appropriate
<PAGE>   9
(as determined by resolution of the Board of Directors of the 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 Fundamental Corporate Change.

         4.5 Other Action Affecting Common Stock. (a) Except with respect to a
Permitted Dilutive Issuance and/or issuances and sales governed by Section
4.5(b) below (including such issuances described in the parenthetical contained
in clause (i)(B) of the first sentence of Section 4.5(b) hereof), if the Company
issues and sells pursuant to an exemption from registration under the Securities
Act (A) Common Shares at a purchase price that is lower than the Current Warrant
Price on the date of issuance of such Common Shares, (B) warrants or options
with an exercise price on the date of issuance thereof that is lower than the
Current Warrant Price for the Holder on such date, or (C) convertible,
exchangeable or exercisable securities with a right to convert or exchange at
lower than the Current Market Price on the date of issuance or conversion, as
applicable, of such convertible, exchangeable or exercisable securities, then
the price at which Common Shares may be purchased upon exercise of this Warrant
shall be reduced to equal the lowest of the Current Warrant Price then in effect
or any such purchase price, exercise price or exchange price, and the number of
shares of Common Stock for which this Warrant is exercisable pursuant to Section
1 shall be correspondingly adjusted. Notwithstanding the foregoing, if an
adjustment is made upon issuance of warrants, options or convertible,
exercisable or exchangeable securities pursuant to clause (B) or (C) above, no
further adjustment pursuant to clause (A) shall be made upon issuance of Common
Shares upon exercise, conversion or exchange thereof.

         (b) Notwithstanding anything to the contrary herein, if at any time,
other than pursuant to a Permitted Dilutive Issuance, the Company (i) (A) issues
to the holders of the Company's Series B Preferred Stock or Series C Preferred
Stock warrants or options to purchase Common Shares, or securities convertible
into or exchangeable for Common Shares, in any such case, at an exercise or
conversion price less than the Current Warrant Price then in effect, or (B)
issues and sells to such holders additional Common Shares (other than upon
exercise of previously issued options or warrants or conversion of previously
issued convertible securities (x) pursuant to the terms in effect on the date
hereof, or as such terms may be adjusted subsequent to the date hereof pursuant
to an Adjustment Event (as hereinafter defined), or (y) pursuant to an Issuance
Event of the type described in clause (i)(A) above pursuant to the terms in
effect at the time of such Issuance Event or as such terms may be adjusted
subsequent to the time of such Issuance Event pursuant to an Adjustment Event)
at a purchase price that is lower than the Current Warrant Price then in effect
(each, an "Issuance Event"), or (ii) adjusts the exercise price of warrants or
options, or the conversion price of convertible securities, previously issued to
the holders of the Company's Series B Preferred Stock or Series C Preferred
Stock to a price less than the Current
<PAGE>   10
Warrant Price then in effect (an "Adjustment Event"), then, from and after the
date of such Issuance Event or Adjustment Event, the Warrant shall be reduced to
equal the lowest of the Current Warrant Price then in effect or the exercise
price of the warrants or options, the conversion price of the convertible
securities or the purchase price of the Common Shares issued pursuant to such
Issuance Event or the exercise price of previously issued warrants or options or
previously issued convertible securities as adjusted pursuant to such Adjustment
Event, as the case may be, and the number of Common Shares for which this
Warrant is exercisable pursuant to Section 1 will be correspondingly adjusted;
provided, however, that no reduction of the Current Warrant Price shall be made
pursuant to this Section 4.5(b) as a result of the occurrence of any Issuance
Event or Adjustment Event unless the aggregate number of additional fully
diluted Common Shares resulting from such Issuance Event or Adjustment Event, as
the case may be, and any previous Issuance Events or Adjustment Events occurring
on or after the Funding Date (in each case calculated in accordance with the
next sentence) exceeds 5,000,000, subject to adjustment for any stock-split or
stock combination or reverse stock split occurring after the Funding Date (the
"Threshold Amount"). Shares counting toward the Threshold Amount shall consist
of: (i) in the case of an Issuance Event involving the issuance of options,
warrants or convertible securities, all Common Shares issuable upon exercise of
such options or warrants or upon conversion of such convertible securities; (ii)
in the case of an Issuance Event involving the issuance and sale of Common
Shares, all Common Shares issued and sold; and (iii) in the case of an
Adjustment Event, a number of Common Shares equal to the difference obtained by
subtracting (x) the number of Common Shares issuable upon exercise of the
options or warrants or upon conversion of the convertible securities subject to
such Adjustment Event, before giving effect to such Adjustment Event from (y)
the number of Common Shares issuable upon exercise of such options or warrants,
or conversion of such convertible securities, after giving effect to such
Adjustment Event. Upon reaching the Threshold Amount, the price at which Common
Shares may be purchased upon exercise of the Warrant shall be adjusted to equal
the lowest of: (A) the Current Warrant Price then in effect, (B) the price at
which any Common Shares were sold, or the exercise or conversion price of any
options, warrants or convertible securities issued, pursuant to any Issuance
Event or (C) the adjusted exercise or conversion price of any options, warrants
or convertible securities subject to any Adjustment Event, provided that for
purposes of making such determination, only the second 2,500,000 shares (the
"Determination Shares") counting toward the Threshold Amount shall be
considered, and provided, further, that, if the Determination Shares include any
Common Shares, options, warrants or convertible securities issued for nominal
consideration or for consideration consisting of an agreement to modify or
release certain claims or contractual rights or other similar agreement to which
no monetary valuation is assigned, then such Common Shares, options, warrants or
convertible securities (the "Excluded Shares") shall not be considered
Determination Shares for purposes of making such adjustment, but, the Company
shall, concurrently with such adjustment, issue and sell to the Holder, at a
price equal to the par value of such shares, a number of Common Shares equal to
the number of Common Shares for which this Warrant is exercisable immediately
prior to such adjustment multiplied by a fraction the numerator of which is the
number of Excluded Shares and the denominator of which is 2,500,000 (subject to
adjustment in each case for any stock-split or stock combination or reverse
stock split occurring after the Funding Date).

         (c) Other than as specifically provided under this Section 4, if at any
time or from time to time the Company shall take any action in respect of its
Common Stock, which would have a
<PAGE>   11
materially adverse effect upon the rights of the Holder, the number of shares of
Common Stock for which this Warrant is exercisable and/or the purchase price
thereof shall be adjusted in such manner as may be equitable in the
circumstances, as determined in good faith by the Board of Directors of the
Company.

         4.6 Certain Limitations. Notwithstanding anything herein to the
contrary, the Company agrees not to enter into any transaction which, by reason
of any adjustment hereunder, would cause the Current Warrant Price to be less
than the par value per share of Common Stock.

5.       NOTICES TO HOLDER

         5.1 Notice of Adjustments. Whenever the number of shares of Common
Stock for which this Warrant is exercisable, or whenever the price at which a
share of such Common Stock may be purchased upon exercise of the Warrants, shall
be adjusted pursuant to this Warrant, the Company shall forthwith prepare a
certificate to be executed by the chief financial officer of the Company setting
forth, in reasonable detail, the event requiring the adjustment and the method
by which such adjustment was calculated (including a description of the basis on
which the Board of Directors of the Company determined the fair value of any
evidences of indebtedness, shares of stock, other securities or property or
warrants or other subscription or purchase rights), specifying the number of
shares of Common Stock for which this Warrant is exercisable and describing the
number and kind of any other shares of stock or Other Property for which this
warrant is exercisable, and any change in the purchase price or prices thereof,
after giving effect to such adjustment or change. The Company shall promptly
cause a signed copy of such certificate to be delivered to the Holder in
accordance with Section 14.2. The Company shall keep at its office or agency
designated pursuant to Section 12 copies of all such certificates and cause the
same to be available for inspection at said office during normal business hours
by the Holder or any prospective purchaser of a Warrant designated by the
Holder.

         5.2 Notice of Corporate Action. If at any time

                  (a) the Company shall take a record of the holders of its
         Common Stock for the purpose of entitling them to receive a dividend 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 the Company,
         any reclassification or recapitalization of the capital stock of the
         Company or any consolidation or merger of the Company with, or any
         sale, transfer or other disposition of all or substantially all the
         property, assets or business of the Company to, another corporation, or

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

then, in any one or more of such cases, the Company shall give to Holder (i) at
least ten 10 business 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
<PAGE>   12
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) business
days' prior written notice of the date when the same shall take place. Such
notice in accordance with the foregoing clause also shall specify (i) 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 (ii) 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 the Company and
delivered in accordance with Section 14.2.

6.       NO IMPAIRMENT

                  (a) The 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 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, the
         Company will (i) 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, (ii) take all such action as may be necessary or
         appropriate in order that the Company may validly and legally issue
         fully paid and nonassessable shares of Common Stock upon the exercise
         of this Warrant, and (iii) 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 the Company
         to perform its obligations under this Warrant.

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

7.       RESERVATION AND AUTHORIZATION OF COMMON STOCK

                  (a) From and after the Funding Date, the 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
<PAGE>   13
         terms of such Warrant, shall be duly and validly issued and fully paid
         and nonassessable, and not subject to preemptive rights.

                  (b) 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, the
         Company shall take any corporate action which may be necessary in order
         that the Company may validly and legally issue fully paid and
         non-assessable shares of such Common Stock at such adjusted Current
         Warrant Price.

                  (c) 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, the 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.

8.       TAKING OF RECORD; STOCK AND WARRANT TRANSFER BOOKS

         In the case of all dividends or other distributions by the 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, the 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. The Company will not at any time, except upon dissolution,
liquidation or winding up of the 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 Shares 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 Shares. Holder, by acceptance of this Warrant, agrees to be bound by
the provisions of this Section 9.

         9.1 Restrictive Legend. The Holder by accepting this Warrant and any
Warrant Shares agrees that unless registered under the Securities Act of 1933,
as amended (the "Securities Act"), subsequent to the Funding Date and prior to
the exercise hereof, this Warrant and the Warrant Shares issuable upon exercise
hereof may not be assigned or otherwise transferred unless and until (i) the
Company has received an opinion of counsel for the Holder reasonably
satisfactory to the Company and its counsel that such securities may be sold
pursuant to an exemption from registration under the Securities Act or (ii) a
registration statement relating to such securities has been filed by the Company
and declared effective by the Commission.

                  (a) Each certificate for Warrant Shares issuable hereunder
         shall bear a legend as follows unless such securities have been sold
         pursuant to an effective registration statement under the Securities
         Act:
<PAGE>   14
                           "These securities have not been registered under the
                  Securities Act of 1933, as amended (the "Securities Act"), or
                  the securities laws of any state, and are being offered and
                  sold pursuant to an exemption from the registration
                  requirements of the Securities Act and such laws. These
                  securities may not be sold or transferred except pursuant to
                  an effective registration statement under the Securities Act
                  or pursuant to an available exemption from the registration
                  requirements of the Securities Act or such other laws."

                  (b) Except as otherwise provided in this Section 9, the
         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 MAY 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 any Transfer or attempted
Transfer of any Warrants or any shares of Restricted Common Stock, the Holder
shall give ten days, prior written notice (a "Transfer Notice") to the Company
and its counsel of Holder's intention to effect such Transfer, describing the
manner and circumstances of the proposed Transfer, and obtain from counsel to
Holder who shall be reasonably satisfactory to the Company, an opinion that the
proposed Transfer of such Warrants or such Restricted Common Stock may be
effected without registration under the Securities Act. After receipt of the
Transfer Notice and opinion, the Company shall, within five (5) business days
thereof, notify the Holder as to whether such opinion is reasonably satisfactory
and, if so, such holder shall thereupon be entitled to Transfer such Warrants or
such Restricted Common Stock, in accordance with the terms of the Transfer
Notice. 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(b), and the Warrant issued upon such Transfer shall bear the
restrictive legend set forth in Section 9.1(c), unless in the opinion of such
counsel such legend is not required in order to ensure compliance with the
Securities Act. The Holder shall not be entitled to Transfer such Warrants or
such Restricted Common Stock until receipt of notice from the Company under this
Section 9.2 that such opinion is reasonably satisfactory.

         9.3 Required Registration. Pursuant to the terms and conditions set
forth in the Registration Rights Agreement, the Company shall prepare and file
with the Commission (X) no earlier than (i) seventy-five (75) days following the
Funding Date or (ii) the date on which the Holder shall have given written
notice to the Company that it has waived its right to exercise the Option (as
defined in the Securities Purchase Agreement), and (Y) no later than one hundred
twenty (120) days after May 15, 2000 (the "Benchmark Date"), a Registration
Statement relating to the offer and sale of all of the Common Stock issuable
upon exercise of the Warrants and shall use its best efforts to cause the
Commission to declare such Registration Statement effective
<PAGE>   15
under the Securities Act as promptly as practicable but not later than one
hundred ninety five (195) days after the Benchmark Date.

         9.4 Termination of Restrictions. Notwithstanding the foregoing
provisions of Section 9, the restrictions imposed by this Section upon the
transferability of the Warrants, the Warrant Shares and the Restricted Common
Stock and the legend requirements of Section 9.1 shall terminate as to any
particular Warrant or Warrant Shares or shares of Restricted Common Stock (i)
when and so long as such security shall have been effectively registered under
the Securities Act and disposed of pursuant thereto or (ii) when the Company
shall have received an opinion of counsel reasonably satisfactory to it and its
counsel 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 the Company upon written request of the Holder, at
the expense of the 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                  ,
                  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 the
Company, at the Company's expense, a new certificate representing such Common
Stock not bearing the restrictive legend set forth in Section 9.1(b).

         9.5 Listing on Securities Exchange. If the Company shall list any
shares of Common Stock on any securities exchange, it 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 so listed during any such Exercise Period.

10.      SUPPLYING INFORMATION

         The Company shall cooperate with Holder in supplying such information
as may be reasonably necessary for 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 the Company from Holder of evidence reasonably
satisfactory to it of the ownership of and the loss, theft, destruction or
mutilation of this Warrant and indemnity
<PAGE>   16
reasonably satisfactory to it (it being understood that the written agreement of
the Holder shall be sufficient indemnity), and in case of mutilation upon
surrender and cancellation hereof, the Company will execute and deliver in lieu
hereof a new Warrant of like tenor to Holder; provided, in the case of
mutilation, no indemnity shall be required if this Warrant in identifiable form
is surrendered to the Company for cancellation.

12.      OFFICE OF THE COMPANY

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

13.      LIMITATION OF LIABILITY

         No provision hereof, in the absence of affirmative action by Holder to
purchase shares of Common Stock, and no enumeration herein of the rights or
privileges of Holder hereof, shall give rise to any liability of Holder for the
purchase price of any Common Stock or as a stockholder of the Company, whether
such liability is asserted by the Company or by creditors of the Company, and
the holder shall have no rights as a shareholder of the Company arising from its
status as a Holder of the Warrants.

14.      MISCELLANEOUS

         14.1 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 the Company fails to make, when due, any payments provided for hereunder, or
fails to comply with any other provision of this Warrant, the Company shall pay
to Holder such amounts as shall be sufficient to cover any reasonable costs and
expenses including, but not limited to, reasonable attorneys' fees, including
those of appellate proceedings, incurred by Holder in collecting any amounts due
pursuant hereto or in otherwise enforcing any of its rights, powers or remedies
hereunder.

         14.2 Notice Generally. Except as may be otherwise provided herein, any
notice or other communication or delivery required or permitted hereunder shall

Holder from and against any liabilities, obligations, losses, damages,

and disbursements of any kind which may be imposed upon, incurred by or asserted
against Holder in any manner relating to or arising out of any failure by the
Company to perform or observe in any material respect any of its covenants,
agreements, undertakings or obligations set forth in this Warrant; provided,
however, that the Company will not be liable hereunder to the extent that any
liabilities, obligations, losses, damages, penalties, actions, judgments, suits,
claims, costs, attorneys' fees, expenses or disbursements are found in a final
non-appealable judgment by a court to have resulted from Holder's gross
negligence, bad faith or willful misconduct in its capacity as a stockholder or

         14.4 Remedies. Holder in addition to being entitled to exercise all
rights granted by law, including recovery of damages, will be entitled to

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.

         14.5 Successors and Assigns. Subject to the provisions of Sections 3.1

amended or the provisions hereof waived with the written consent of the Company
and the Holder.

         14.7 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.

         14.8 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.

         14.9 Governing Law. This Warrant shall be governed by the laws of the
State of Delaware, without regard to the provisions thereof relating to conflict
of laws.

               IN WITNESS WHEREOF, the Company has caused this Warrant to be
duly executed and its corporate seal to be impressed hereon.
