            2. EXERCISE OF WARRANT

            2.1 Manner of Exercise

            From and after April 30, 2000 and until 5:00 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 the Company at its principal office at 150 East 58th Street, Suite
3400, New York, New York 10155, 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) to the extent such exercise is not being effected
through a Cashless Exercise, payment of the Warrant Price in cash or 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 five 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 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

                                      -4-

<PAGE>

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 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, 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 Stock otherwise than in accordance with this
Warrant.

            Simultaneously with the exercise of this Warrant, payment in full of
the Warrant Price may be made, at the option of the Holder, (i) by payment of
the Warrant Price in cash or by wire transfer or cashier's check drawn on a
United States bank, (ii) without payment of the Warrant Price by surrender of
certificate(s) evidencing the Warrants (the "WARRANT CERTIFICATE") in exchange
for a number of shares equal to the product of (l) the number of shares for
which such Warrant is exercisable with payment of the Warrant Price as of the
date of exercise and (2) the Cashless Exercise Ratio or (iii) by any combination
of (i) and (ii). For purposes of this Agreement, the "CASHLESS EXERCISE RATIO"
shall equal a fraction, the numerator of which is the excess of the Current
Market Price on the date of exercise over the Current Warrant Price as of the
date of exercise and the denominator of which is the Current Market Price on the
date of exercise. An exercise of a Warrant in accordance with the clause (ii) in
the first sentence of this paragraph is herein called a "CASHLESS EXERCISE."
Upon surrender of a Warrant Certificate representing more than one Warrant in
connection with the Holder's option to elect a Cashless Exercise, the number of
shares deliverable upon a Cashless Exercise shall be equal to the Cashless
Exercise Ratio multiplied by the product of (a) the number of Warrants that the
Holder specifies is to be exercised pursuant to a Cashless Exercise and (b) the
number of shares for which such Warrant is then exercisable (without giving
effect to the Cashless Exercise option). All provisions of this Agreement shall
be applicable with respect to an exercise of a Warrant Certificate pursuant to a
Cashless Exercise for less than the full number of Warrants represented thereby.

            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, freely tradable and without any preemptive rights. The 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. 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

                                      -5-

<PAGE>

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
Closing 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 Section 9, 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 finds 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 canceled. 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 the
Company, together with a written notice specifying the names and denominations
in which new Warrants are to be

                                      -6-

<PAGE>

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 Warrants 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;

            (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 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

                                      -7-

<PAGE>

            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 the 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:

            (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 stockholders thereof, legally abandon
its plan to pay or deliver such dividend, distribution, subscription or purchase
rights, then thereafter no adjustment shall be required by reason of the taking
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

                                      -8-

<PAGE>

the Holder, and any dispute shall be resolved by an investment banking firm of
recognized national standing selected by the Company and acceptable to 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 corporation (where the
Company is not the surviving corporation or where there is a change in or
distribution with respect to the Common Stock of the Company), or sell, transfer
or otherwise dispose of all or substantially all its property, assets or
business to another corporation and, pursuant to the terms of such
reorganization, reclassification, merger, consolidation or disposition of
assets, 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, the 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 receivable upon or as a result of such reorganization,
reclassification, 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 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 (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 still similarly apply to successive reorganizations,
reclassifications, mergers, consolidations or disposition of assets.

            4.5 Other Action Affecting Common Stock

            In case at any time or from time to time the Company shall take any
action in respect of its Common Stock, other than any action described in this
Section 4, which would have a materially adverse effect upon the rights of
Holder, the number of shares of Common Stock 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

                                      -9-

<PAGE>

            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

the chief financial officer of the Company setting forth, in reasonable detail,

such adjustment or change. The Company shall promptly cause a signed copy of

The Company shall keep at its office or agency designated pursuant to Section 12

            5.2 Notice of Corporate Action

            If at any time:

property, or to receive any other right; or

            (b) there shall be any capital reorganization of the Company, any

            (c) there shall be a voluntary or involuntary dissolution,

winding up, and (ii) in the case of any such reorganization, reclassification,
merger, consolidation, sale, transfer, disposition, dissolution, liquidation or
winding up, at least 30 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

            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 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 (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 the 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 the Company to perform
its obligations under this Warrant.

            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

            From and after the Closing 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 terms of such Warrant, shall be duly and
validly issued and fully paid and nonassessable and not subject to preemptive
rights.

                                      -11-

<PAGE>

            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 nonassessable 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, 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 record of such holders, the Company will in
each 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 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. Holder, by acceptance of this Warrant, agrees to be bound by
the provisions of this Section 9.

            9.1 Restrictive Legend

            (a) Holder, by accepting this Warrant and any Warrant Stock agrees
that this Warrant and the Warrant Stock issuable upon exercise hereof may not be
assigned or otherwise transferred unless and until (i) the Company has received
an opinion of counsel for Holder 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.

            Each certificate for Warrant Stock issuable hereunder shall bear a
legend as follows until such securities have been sold pursuant to an effective
registration statement under the Securities Act:

            "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

                                      -12-

<PAGE>

            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 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 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(a), and the Warrant issued upon such Transfer
shall bear the restrictive legend set forth in Section 9.1(b), unless in the
opinion of such counsel such legend is not required in order to ensure
compliance with the Securities Act. 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(a) that such opinion is reasonably satisfactory.

            9.3 Required Registration

            Pursuant to the terms and conditions set forth in Registration
Rights Agreement, the Company shall prepare and file with the Commission not
later than the 75th day after the Closing Date, a Registration Statement
relating to the offer and sale 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 under the Securities Act as promptly as
practicable but no later than April 30, 2000.

                                      -13-

            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 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) (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 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(a).

            9.5 Listing on Securities Exchange

            If the Company shall list any shares of Common Stock on any
securities exchange or quotation system, 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 reasonably satisfactory to it (it being
understood that the written agreement of the Holder shall be

                                      -14-

<PAGE>

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.

            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 costs and expenses including, without
limitation, 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 be in writing

<PAGE>

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,

            14.4 Remedies

            Holder in addition to being entitled to exercise all rights granted
by law, including recovery of damages, will be entitled to specific performance
of its rights under Section 9 of this Warrant. The 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.

            14.5 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 and be binding upon
the successors of the Company and the successors and assigns of Holder. The
provisions of this Warrant are intended to be for the benefit of all Holders
from time to time of this Warrant and, with respect to Section 9 hereof, holders
of Warrant Stock, and shall be enforceable by any such Holder or holder of
Warrant Stock.

            14.6 Amendment

            This Warrant and all other Warrants may be modified or amended or
the provisions hereof waived with the written consent of the Company and 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,

prohibition or invalidity, without invalidating the remainder of such provision
or the remaining provisions of this Warrant.

            14.8 Headings

            (h) takes any action affecting the number of Outstanding Capital
Shares, other than an action described in any of the foregoing Sections 6.1(a)
through 6.1(g) hereof, inclusive, which in the opinion of the Holder, determined
in good faith, would have a material adverse effect upon the rights of the
Holder at the time of any conversion of Preferred Stock or its reasonably likely
to result in a decrease in the Market Price.

            SECTION 6.2 EXERCISE OF CONVERSION PRIVILEGE

            (a) Conversion of the Series E Preferred Stock may be exercised, in
whole or in part, by the Holder by telecopying an executed and completed
Conversion Notice to the Corporation. Each date on which a Conversion Notice is
telecopied to the Corporation in accordance with the provisions of this Section
6.2 shall constitute a Conversion Date. The Corporation shall convert the
Preferred Stock and issue the Common Stock Issued at Conversion, and all voting
and other rights associated with the beneficial ownership of the Common Stock
issued at Conversion shall vest with the Holder, effective as of the conversion
Date at the time specified in the Conversion Notice. The Conversion Notice also
shall state the name or names (with addresses) of the Persons who are to become
the holders of the Common Stock Issued at Conversion in connection with such
conversion. The Holder shall deliver the shares of Series E Preferred Stock to
the Corporation by express courier with 30 days following the date on which the
telecopied Conversion Notice has been transmitted to the Corporation. Upon
surrender for conversion, the Preferred Stock shall be accompanied by a proper
assignment thereof to the Corporation or be endorsed in blank. As promptly as
practicable after the receipt of the Conversion Notice as aforesaid, but in any
event not more than five Business Days after the Corporation's receipt of such
Conversion Notice, the Corporation shall (i) issue the Common Stock issued at
Conversion in accordance with the provisions of this Article 6, and (ii) cause
to be mailed for delivery by overnight courier to the Holder (x) a certificate
or certificate(s) representing the number of Common Shares to which the Holder
is entitled by virtue of such

                                      -9-

<PAGE>

conversion, (y) cash, as provided in Section 6.3, in respect of any fraction of
a Common Share issuable upon such conversion and (z) if the Corporation chooses
to pay accrued and unpaid dividends in cash, cash in the amount of accrued and
unpaid dividends as of the Conversion Date. Such conversion shall be deemed to
have been effected at the time at which the Conversion Notice indicates so long
as the Series E Preferred Stock shall have been surrendered as aforesaid at such
time, and at such time the rights of the Holder of the Series E Preferred Stock,
as such, shall cease and the Person or Persons in whose name or names the Common
Stock Issued at Conversion shall be issuable shall be deemed to have become the
holder or holders of record of the Common Shares represented thereby and all
voting and other rights associated with the beneficial ownership of such Common
Shares shall at such time vest with such Person or Persons. The Conversion
Notice shall constitute a contract between the Holder and the Corporation,
whereby the Holder shall be deemed to subscribe for the number of Common Shares
which it will be entitled to receive upon such conversion and, in payment and
satisfaction of such subscription (and for any cash adjustment to which it is
entitled pursuant to Section 6.3), to surrender the Series E Preferred Stock and
to release the Corporation from all liability thereon. No cash payment
aggregating less than $1.00 shall be required to be given unless specifically
requested by the Holder.

            (b) If, at any time (i) the Corporation challenges, disputes or
denies the rights of the Holder thereof to effect the conversion of the Series E
Preferred Stock into Common Shares or otherwise dishonors or rejects any
Conversion Notice delivered in accordance with this Section 6.2 or (ii) any
third party commences any lawsuit or proceeding or otherwise asserts any claim
before any court or public or governmental authority which seeks to challenge,
deny, enjoin, limit, modify, delay or dispute the right of the Holder hereof to
effect the conversion of the Series E Preferred Stock into Common Shares (a
"BLOCKAGE CLAIM"), and such Blockage Claim shall remain in effect and not be
resolved for a period of more than 90 days, then the Holder shall have the
right, by written notice to the Corporation, to require the Corporation to
promptly redeem the Series E Preferred Stock for cash at a redemption price
equal to 105% of the Stated Value thereof together with all accrued and unpaid
dividends thereon (the "MANDATORY PURCHASE AMOUNT"). Under any of the
circumstances set forth above, the Corporation shall be responsible for the
payment of all costs and expenses of the Holder, including reasonable legal fees
and expenses, as and when incurred in disputing any such action or pursuing its
rights hereunder (in addition to any other rights of the Holder).

            (c) The Holder shall be entitled to exercise its conversion
privilege notwithstanding the commencement of any case under 11 U.S.C. Section
101 et seq. (the "BANKRUPTCY CODE"). In the event the Corporation is a debtor
under the Bankruptcy Code, the Corporation hereby waives to the fullest extent
permitted any rights to relief it may have under 11 U.S.C. Section 362 in
respect of the Holder's conversion privilege. The Corporation hereby waives to
the fullest extent permitted any rights to relief it may have under 11 U.S.C.
Section 362 in respect of the conversion of the Series E Preferred Stock. The
Corporation agrees, without cost or expense to the Holder, to take or consent to
any and all action necessary to effectuate relief under 11 U.S.C. Section 362.

                                      -10-

<PAGE>

            SECTION 6.3 FRACTIONAL SHARES

            No fractional Common Shares or scrip representing fractional Common
Shares shall be issued upon conversion of the Series E Preferred Stock. Instead
of any fractional Common Shares which otherwise would be issuable upon
conversion of the Series E Preferred Stock, the Corporation shall pay a cash
adjustment in respect of such fraction in an amount equal to the same fraction.

            SECTION 6.4 ADJUSTMENTS TO CONVERSION PRICE

            Except with respect to issuances of Capital Shares in connection
with an acquisition or merger where the Board of Directors of the Corporation
determines in good faith that such Capital Shares are not being issued for
consideration lower than the Current Market Price in effect immediately prior to
such issuances, for so long as any shares of the Series E Preferred Stock are
outstanding, if the Corporation issues and sells pursuant to an exemption from
registration under the Securities Act (A) Common Shares at a purchase price on
the date of issuance thereof that is lower than the Conversion Price, (B)
warrants or options with an exercise price on the date of issuance thereof that
is lower than the Conversion Price for the Holder on such date, except for
warrants or options issued pursuant to employee benefit plans consistent with
those presently in effect, employee stock option agreements or stock incentive
agreements of the Corporation, or (C) convertible, exchangeable or exercisable
securities with a right to exchange at lower than the Current Market Price on
the date of issuance or conversion, as applicable, of such convertible,
exchangeable or exercisable securities, except for stock option agreements or
stock incentive agreements, then on any date on which the Conversion Price shall
be determined, the Conversion Price shall be reduced by an amount equal to the
amount by which the purchase price, exercise price or exchange price, as
applicable, is lower than the Conversion Price or Current Market Price, as
applicable, multiplied by a fraction the denominator of which is $2,500,000 and
the numerator of which is the sum of (A) the aggregate number of (i) Common
Shares, in the case of (A) above, (ii) Common Shares into which the warrants or
options are exchangeable into, in the case of (B) above, or (iii) equity
securities into which the convertible or exchangeable securities are exercisable
into, in the case of (C) above, multiplied by (B) the Conversion Price, in each
case, with a maximum adjustment equal to the applicable discount triggering such
adjustment pursuant to this Section 6.4.

            SECTION 6.5 OPTIONAL REDEMPTION

            (a) At any time on or before April 30, 2000 (the "APRIL 30, 2000
REDEMPTION DATE") the Corporation, upon notice delivered to the Holder as
provided in Section 6.6, may redeem the Series E Preferred Stock for a
redemption price of $2,800,000, together with all unpaid dividends thereon
through April 30, 2000, whether or not accrued, in each case in cash (the
"SECTION 6.5(A) OPTIONAL REDEMPTION PRICE").

            (b) At any time after the April 30, 2000 Redemption Date until the
Mandatory Conversion Date, the Corporation, upon notice delivered to the Holder
as provided in Section 6.6, may redeem, in cash, the Series E Preferred Stock
(but only with respect to such shares as to which the Holder has not theretofore
furnished a Conversion Notice in compliance with Section 6.2), at the Stated
Value thereof (the "SECTION 6.5(B) OPTIONAL REDEMPTION PRICE"), together

                                      -11-

<PAGE>

with all accrued an unpaid dividends thereon to the date of redemption (the
SECTION 6.5(B) REDEMPTION DATE" and, together with the April 30, 2000 Redemption
Date, the "REDEMPTION DATE").

            (c) The Section 6.5(a) Redemption Price and the Section 6.5(b)
Redemption Price, as applicable, as referred to herein as the "OPTIONAL
REDEMPTION PRICE." Except as set forth in this Section 6.5, the Corporation
shall not have the right to redeem the Series E Preferred Stock.

            SECTION 6.6 NOTICE OF REDEMPTION

            Notice of redemption pursuant to Section 6.5 shall be provided by
the Corporation to the Holder in writing (by registered mail or overnight
courier at the Holder's last address appearing in the Corporation's security
registry) not less than ten nor more than 15 days prior to the Redemption Date,
which notice shall specify the Redemption Date and refer to Section 6.5
(including a statement of the Current Market Price per Common Share) and this
Section 6.6.

            SECTION 6.7 SURRENDER OF PREFERRED STOCK.

            Upon any redemption of the Series E Preferred Stock pursuant to
Sections 6.5 and 6.6, the Holder shall either deliver the Series E Preferred
Stock by hand to the Corporation at its principal executive offices or surrender
the same to the Corporation at such address by express courier within 14 days
after the date that the Buyer receives payment therefore. Payment of the
Optional Redemption Price shall be made by the Corporation to the Holder by wire
transfer of immediately available funds to such account(s) as the Holder shall
specify to the Corporation. If payment of such Optional Redemption Price is not
made in full by the Redemption Date, the Holder shall again have the right to
convert the Series E Preferred Stock as provided in Article 6 hereof.

            SECTION 6.8 MANDATORY CONVERSION

            On the 42nd (forty second) calendar month anniversary of the Issue
Date (the "MANDATORY CONVERSION DATE"), the Corporation shall convert all Series
E Preferred Stock outstanding at the Conversion Price utilizing the Stated Value
(plus accrued and unpaid dividends) as the value of each share of Series E
Preferred Stock, into Common Stock which is registered for sale in open market
transactions on the Registration Statement (as defined in the Registration
Rights Agreement), which Registration Statement shall then be effective under
the Securities Act.

            SECTION 6.9 CERTAIN CONVERSION LIMITATIONS

            (a) Notwithstanding anything herein to the contrary, the Holder
shall not have the right, and the Corporation shall not have the obligation, to
convert all or any portion of the Series E Preferred Stock (and the Corporation
shall not have the right to pay dividends on the Series E Preferred Stock in
shares of Common Stock) if and to the extent that the issuance to the Holder of
shares of Common Stock upon such conversion (or payment of dividends) would
result in the Holder being deemed the "beneficial owner" of more than 5% of the
then Outstanding shares of Common Stock within the meaning of Section 13(d) of
the Securities

                                      -12-

<PAGE>

Exchange Act of 1934, as amended, and the rules promulgated thereunder. If any
court of competent jurisdiction shall determine that the foregoing limitation is
ineffective to prevent a Holder from being deemed the beneficial owner of more
than 5% of the then Outstanding shares of Common Stock, then the Corporation
shall redeem so many of such Holder's shares (the "REDEMPTION SHARES") of Series
E Preferred Stock as are necessary to cause such Holder to be deemed the
beneficial owner of not more than 5% of the then Outstanding shares of Common
Stock. Upon such determination by a court of competent jurisdiction, the
Redemption Shares shall immediately and without further action be deemed
returned to the status of authorized but unissued shares of Series E Preferred
Stock, and the Holder shall have no interest in or rights under such Redemption
Shares. Any and all dividends paid on or prior to the date of such determination
shall be deemed dividends paid on the remaining shares of Series E Preferred
Stock held by the Holder. Such redemption shall be for cash at a redemption
price equal to the sum of (i) 105% of the Stated Value of the Redemption Shares
and (ii) any accrued and unpaid dividends to the date of such redemption.

            (b) Unless the Corporation shall have obtained the approval of its
voting stockholders to such issuance in accordance with the rules of the Amex or
such other stock market with which the Corporation shall be required to comply,
but only to the extent required thereby, the Corporation shall not issue shares
of Common Stock (i) upon conversion of any shares of Series E Preferred Stock or
(ii) as a dividend on the Series E Preferred Stock, if such issuance of Common
Stock, when added to the number of shares of Common Stock previously issued by
the Corporation (i) upon conversion of shares of the Series E Preferred Stock,
(ii) upon exercise of the Warrants issued pursuant to the terms of the
Securities Purchase Agreement and (iii) in payment of dividends on the Series E
Preferred Stock, would equal or exceed 20% of the number of shares of the
Corporation's Common Stock which were issued and Outstanding on the Issue Date
(the "MAXIMUM ISSUANCE AMOUNT"). In the event that a properly executed
Conversion Notice is received by the Corporation which would require the
Corporation to issue shares of Common Stock equal to or in excess of the Maximum
Issuance Amount, the Corporation shall honor such conversion request by (i)
converting the number of shares of Series E Preferred Stock stated in the
Conversion Notice not in excess of the Maximum Issuance Amount and (ii)
redeeming the number of shares of Series E Preferred Stock stated in the
Conversion Notice equal to or in excess of the Maximum Issuance Amount in cash
at a price equal to 105% of the Stated Value of the shares of Series E Preferred
Stock to be so redeemed, together with all accrued and unpaid dividends thereon.
In the event that the Corporation shall elect to pay a dividend in shares of
Common Stock which would require the Corporation to issue shares of Common Stock
equal to or in excess of the Maximum Issuance Amount, the Corporation shall pay
(i) a dividend in shares of Common Stock equal to one less than an amount which
would result in the Corporation issuing shares equal to the Maximum Issuance
Amount and (ii) the balance of the dividend in cash.

                                   ARTICLE 7
                                 VOTING RIGHTS

            The Holders of the Series E Preferred Stock have no voting power,
except as otherwise provided by the General Corporation Law of the State of
Delaware ("DGCL"), in this Article 7, and in Article 8 below.

                                      -13-

<PAGE>

            Notwithstanding the above, the Corporation shall provide each Holder
of Series E Preferred Stock with prior notification of any meeting of the
shareholders (and copies of proxy materials and other information sent to
shareholders). In the event of any taking by the Corporation of a record of its
shareholders for the purpose of determining shareholders who are entitled to
receive payment of any dividend or other distribution, any right to subscribe
for, purchase or otherwise acquire (including by way of merger, consolidation or
recapitalization) any share of any class or any other securities or property, or
to receive any other right, or for the purpose of determining shareholders who
are entitled to vote in connection with any proposed liquidation, dissolution or
winding up of the Corporation, the Corporation shall mail a notice to each
Holder, at least 30 days prior to the consummation of the transaction or event,
whichever is earlier), of the date on which any such action is to be taken for
the purpose of such dividend, distribution, right or other event, and a brief
statement regarding, the amount and character of such dividend, distribution,
right or other event to the extent known at such time.

            To the extent that under the DGCL the vote of the Holders of the
Section E Preferred Stock, voting separately as a class or series as applicable,
is required to authorize a given action of the Corporation, the affirmative vote
or consent of the Holders of at least a majority of the outstanding shares of
Series E Preferred Stock represented at a duly held meeting at which a quorum is
present or by written consent of a majority of the outstanding shares of Series
E Preferred Stock (except as otherwise may be required under the DGCL) shall
constitute the approval of such action by the class. To the extent that under
the DGCL Holders of the Series E Preferred Stock are entitled to vote on a
matter with holders of Common Stock, voting together as one class, each share of
Series E Preferred Stock shall be entitled to a number of votes equal to the
number of shares of Common Stock into which it is then convertible using the
record date for the taking of such vote of shareholders as the date as of which
the Conversion Price is calculated. Holders of the Series E Preferred Stock
shall be entitled to notice of all shareholder meetings or written consents (and
copies of proxy materials and other information sent to shareholders) with
respect to which they would be entitled to vote, which notice would be provided
pursuant to the Corporation's bylaws and the DGCL.

                                    ARTICLE 8
                              PROTECTIVE PROVISIONS

            So long as shares of Series E Preferred Stock are outstanding, the
Corporation shall not, without first obtaining the approval (by vote or written
consent, as provided by the DGCL) of the Holders of at least a majority of the
then outstanding shares of Series E Preferred Stock:

            (a) alter or change the rights, preferences or privileges of the
Series E Preferred Stock;

            (b) create any new class or series of capital stock having a
preference over the Series E Preferred Stock as to distribution of assets upon
liquidation, dissolution or winding up of the Corporation ("SENIOR SECURITIES")
or alter or change the rights, preferences or privileges of any Senior
Securities so as to affect adversely the Series E Preferred Stock;

            (c) increase the authorized number of shares of Series E Preferred
Stock; or

                                      -14-

<PAGE>

            (d) do any act or thing not authorized or contemplated by this
Certificate of Designation which would result in taxation of the Holders of the
Series E Preferred Stock under Section 305 of the Internal Revenue Code of 1986,
as amended (or any comparable provision of the Internal Revenue Code as
hereafter from time to time amended).

            In the event Holders of least a majority of the then outstanding
shares of Series E Preferred Stock agree to allow the Corporation to alter or
change the rights, preferences or privileges of the shares of Series Preferred
Stock, pursuant to subsection (a) above, so as to affect the Series E Preferred
Stock, then the Corporation will deliver notice of such approved change to the
Holders of the Series Preferred Stock that did not agree to such alteration or
change (the "DISSENTING HOLDERS") and Dissenting Holders shall have the right
for a period of 30 days to convert pursuant to the terms of this Certificate of
Designation as in effect prior to such alteration or change or continue to hold
their shares of Series E Preferred Stock.

            Notwithstanding anything to the contrary herein, if at any time the
Corporation shall "spin-off" certain of its assets or businesses by
transferring, directly, or indirectly, such assets or businesses to a Subsidiary
of the Corporation ("SPINCO") and making a dividend (the "SPIN-OFF DIVIDEND") to
the Corporation's stockholders of the shares of capital stock of Spinco, then
prior to making the Spin-Off Dividend, the Corporation shall cause Spinco to
issue to each Holder that number of shares of preferred stock of Spinco with
substantially identical rights, preferences, privileges, powers, restrictions
and other terms as the Series E Preferred Stock equal to the number of shares of
Series E Preferred Shares held by such Holder immediately prior to the Spin-Off
Dividend.

                                   ARTICLE 9

and, in the case of any such loss, theft or destruction, upon receipt of
indemnity or security reasonably satisfactory to the Corporation, or, in the
case of such mutilitation, upon surrender and cancellation of the Series E
Preferred Stock, the Corporation shall make, issue and deliver, in lieu of such
lost, stolen, destroyed or mutilated shares of Series E Preferred Stock, new
shares of Series E Preferred Stock of like tenor. The Series E Preferred Stock
shall be held and owned upon the express condition that the provisions of this
Section 9.1 are exclusive with respect to the replacement of mutilated,
destroyed, lost or stolen shares of Series E Preferred Stock and shall preclude
any and all other rights and remedies notwithstanding any law or statute
existing or hereafter enacted to the contrary with respect to the replacement of
negotiable instruments or other securities without the surrender thereof.

            SECTION 9.2 WHO DEEMED ABSOLUTE OWNER

            The Corporation may deem the Person in whose name the Series E
Preferred Stock shall be registered upon the registry books of the Corporation
to be, and may treat it as, the absolute owner of the Series E Preferred Stock
for the purpose of receiving payment of dividends

                                      -15-

Stock and for all other purposes, and the Corporation shall not be affected by
any notice to the contrary. All such payments and such conversion shall be valid
and effectual to satisfy and discharge the liability upon the Series E Preferred
Stock to the extent of the sum or sums so paid or the conversion so made.

      SECTION 9.3 NOTICE OF CERTAIN EVENTS

      In the case of the occurrence of any event described in Sections 5(b), 6.5
or 6.6 of this Certificate of Designation, the Corporation shall cause to be

      The undersigned owner of this Series E Convertible Preferred Stock (the
