            1.2 Fair Market Value. For purposes hereof, the "Fair Market Value"

writing its continuing obligation to afford to such holder any rights to which

            1.4 Trustee for Warrant Holders. In the event that a bank or trust
company shall have been appointed as trustee for the holders of the Warrant
pursuant to Subsection 3.2, such bank or trust company shall have all the powers
and duties of a warrant agent (as hereinafter described) and shall accept, in
its own name for the account of the Company or such successor person as may be
entitled thereto, all amounts otherwise payable to the Company or such
successor, as the case may be, on exercise of this Warrant pursuant to this
Section 1.

         2. Procedure for Exercise.

            2.1 Delivery of Stock Certificates, Etc., on Exercise. The Company
agrees that the shares of Common Stock purchased upon exercise of this Warrant
shall be deemed to be issued to the Holder as the record owner of such shares as
of the close of business on the date on which this Warrant shall have been
surrendered and payment made for such shares in accordance herewith. As soon as
practicable after the exercise of this Warrant in full or in part, and in any
event within three (3) business days thereafter, the Company at its expense
(including the payment by it of any applicable issue taxes) will cause to be
issued in the name of and delivered to the Holder, or as such Holder (upon
payment by such Holder of any applicable transfer taxes) may direct in
compliance with applicable securities laws, a certificate or certificates for
the number of duly and validly issued, fully paid and nonassessable shares of
Common Stock (or Other Securities) to which such Holder shall be entitled on
such exercise, plus, in lieu of any fractional share to which such holder would
otherwise be entitled, cash equal to such fraction multiplied by the then Fair
Market Value of one full share, together with any other stock or other
securities and property (including cash, where applicable) to which such Holder
is entitled upon such exercise pursuant to Section 1 or otherwise.

            2.2 Exercise. Payment may be made either (i) in cash or by certified
or official bank check payable to the order of the Company equal to the
applicable aggregate Exercise Price, (ii) by delivery of the Warrant, or shares
of Common Stock and/or Common Stock receivable upon exercise of the Warrant in
accordance with Section (b) below, or (iii) by a combination of any of the
foregoing methods, for the number of Common Shares specified in such Exercise
Notice (as such exercise number shall be adjusted to reflect any adjustment in
the total number of shares of Common Stock issuable to the Holder per the terms
of this Warrant) and the Holder shall thereupon be entitled to receive the
number of duly authorized, validly issued, fully-paid and non-assessable shares
of Common Stock (or Other Securities) determined as provided herein.
Notwithstanding any provisions herein to the contrary, if the Fair Market Value
of one share of Common Stock is greater than the Exercise Price (at the date of
calculation as set forth below), in lieu of exercising this Warrant for cash,
the Holder may elect to receive shares equal to the value (as determined below)
of this Warrant (or the portion thereof being exercised) by surrender of this
Warrant at the principal office of the Company together with the properly
endorsed Exercise Notice in which event the Company shall issue to the Holder a
number of shares of Common Stock computed using the following formula:

         X=Y            (A-B)
                       ---------
                          A



                                       3
<PAGE>

         Where X = the number of shares of Common Stock to be issued to the
                   Holder

         Y = the number of shares of Common Stock purchasable
             under the Warrant or, if only a portion of the
             Warrant is being exercised, the portion of the
             Warrant being exercised (at the date of such
             calculation)

         A = the Fair Market  Value of one share of the  Company's
             Common Stock (at the date of such calculation)

         B = Exercise Price (as adjusted to the date of such
             calculation)

         3. Effect of Reorganization, Etc.; Adjustment of Exercise Price.

            3.1 Reorganization, Consolidation, Merger, Etc. In case at any time
or from time to time, the Company shall (a) effect a reorganization, (b)
consolidate with or merge into any other person, or (c) transfer all or
substantially all of its properties or assets to any other person under any plan
or arrangement contemplating the dissolution of the Company, then, in each such
case, as a condition to the consummation of such a transaction, proper and
adequate provision shall be made by the Company whereby the Holder of this
Warrant, on the exercise hereof as provided in Section 1 at any time after the
consummation of such reorganization, consolidation or merger or the effective
date of such dissolution, as the case may be, shall receive, in lieu of the
Common Stock (or Other Securities) issuable on such exercise prior to such
consummation or such effective date, the stock and other securities and property
(including cash) to which such Holder would have been entitled upon such
consummation or in connection with such dissolution, as the case may be, if such
Holder had so exercised this Warrant, immediately prior thereto, all subject to
further adjustment thereafter as provided in Section 4.

            3.2 Dissolution. In the event of any dissolution of the Company
following the transfer of all or substantially all of its properties or assets,
the Company, concurrently with any distributions made to holders of its Common
Stock, shall at its expense deliver or cause to be delivered to the Holder the
stock and other securities and property (including cash, where applicable)
receivable by the Holder of the Warrant pursuant to Section 3.1, or, if the
Holder shall so instruct the Company, to a bank or trust company specified by
the Holder and having its principal office in New York, NY as trustee for the
Holder of the Warrant (the "Trustee").

            3.3 Continuation of Terms. Upon any reorganization, consolidation,
merger or transfer (and any dissolution following any transfer) referred to in
this Section 3, this Warrant shall continue in full force and effect and the
terms hereof shall be applicable to the shares of stock and other securities and
property receivable on the exercise of this Warrant after the consummation of
such reorganization, consolidation or merger or the effective date of
dissolution following any such transfer, as the case may be, and shall be
binding upon the issuer of any such stock or other securities, including, in the
case of any such transfer, the person acquiring all or substantially all of the
properties or assets of the Company, whether or not such person shall have
expressly assumed the terms of this Warrant as provided in Section 4. In the
event this Warrant does not continue in full force and effect after the
consummation of the transactions described in this Section 3, then the Company's
securities and property (including cash, where applicable) receivable by the
Holders of the Warrant will be delivered to Holder or the Trustee as
contemplated by Section 3.2.

         4. Extraordinary Events Regarding Common Stock. In the event that the
Company shall (a) issue additional shares of the Common Stock as a dividend or
other distribution on outstanding Common Stock, (b) subdivide its outstanding
shares of Common Stock, or (c) combine its outstanding shares of the Common
Stock into a smaller number of shares of the Common Stock, then, in each such
event, the Exercise Price shall, simultaneously with the happening of such
event, be adjusted by multiplying the then Exercise Price by a fraction, the
numerator of which shall be the number of shares of Common Stock outstanding
immediately prior to such event and the denominator of which shall be the number
of shares of Common Stock outstanding immediately after such event, and the
product so obtained shall thereafter be the Exercise Price then in effect. The
Exercise Price, as so adjusted, shall be readjusted in the same manner upon the
happening of any successive event or events described herein in this Section 4.
The number of shares of Common Stock that the holder of this Warrant shall
thereafter, on the exercise hereof as provided in Section 1, be entitled to
receive shall be increased to a number determined by multiplying the number of
shares of Common Stock that would otherwise (but for the provisions of this
Section 4) be issuable on such exercise by a fraction of which (a) the numerator
is the Exercise Price that would otherwise (but for the provisions of this
Section 4) be in effect, and (b) the denominator is the Exercise Price in effect
on the date of such exercise.

         5. Certificate as to Adjustments. In each case of any adjustment or
readjustment in the shares of Common Stock (or Other Securities) issuable on the
exercise of the Warrant, the Company at its expense will promptly cause its
Chief Financial Officer or other appropriate designee to compute such adjustment
or readjustment in accordance with the terms of the Warrant and prepare a
certificate setting forth such adjustment or readjustment and showing in detail
the facts upon which such adjustment or readjustment is based, including a
statement of (a) the consideration received or receivable by the Company for any
additional shares of Common Stock (or Other Securities) issued or sold or deemed
to have been issued or sold, (b) the number of shares of Common Stock (or Other
Securities) outstanding or deemed to be outstanding, and (c) the Exercise Price
and the number of shares of Common Stock to be received upon exercise of this
Warrant, in effect immediately prior to such adjustment or readjustment and as
adjusted or readjusted as provided in this Warrant. The Company will forthwith
mail a copy of each such certificate to the holder of the Warrant and any
Warrant agent of the Company (appointed pursuant to Section 11 hereof).

         6. Reservation of Stock, Etc., Issuable on Exercise of Warrant. The
Company will at all times reserve and keep available, solely for issuance and
delivery on the exercise of the Warrant, shares of Common Stock (or Other
Securities) from time to time issuable on the exercise of the Warrant.

         7. Assignment; Exchange of Warrant. Subject to compliance with
applicable securities laws, this Warrant, and the rights evidenced hereby, may
be transferred by any registered holder hereof (a "Transferor") in whole or in
part. On the surrender for exchange of this Warrant, with the Transferor's
endorsement in the form of Exhibit B attached hereto (the "Transferor
Endorsement Form") and together with evidence reasonably satisfactory to the
Company demonstrating compliance with applicable securities laws, which shall
include, without limitation, the provision of a legal opinion from the
Transferor's counsel (at the Company's expense) that such transfer is exempt
from the registration requirements of applicable securities laws, and with
payment by the Transferor of any applicable transfer taxes) will issue and
deliver to or on the order of the Transferor thereof a new Warrant of like
tenor, in the name of the Transferor and/or the transferee(s) specified in such
Transferor Endorsement Form (each a "Transferee"), calling in the aggregate on
the face or faces thereof for the number of shares of Common Stock called for on
the face or faces of the Warrant so surrendered by the Transferor.



                                       5
<PAGE>

         8. Replacement of Warrant. On receipt of evidence reasonably
satisfactory to the Company of the loss, theft, destruction or mutilation of
this Warrant and, in the case of any such loss, theft or destruction of this
Warrant, on delivery of an indemnity agreement or security reasonably
satisfactory in form and amount to the Company or, in the case of any such
mutilation, on surrender and cancellation of this Warrant, the Company at its
expense will execute and deliver, in lieu thereof, a new Warrant of like tenor.

         9. Registration Rights. The Holder of this Warrant has been granted
certain registration rights by the Company. These registration rights are set
forth in a Registration Rights Agreement entered into by the Company and
Purchaser dated as of even date of this Warrant.

         10. Maximum Exercise. The Holder shall not be entitled to exercise this
Warrant on an exercise date, in connection with that number of shares of Common
Stock which would be in excess of the sum of (i) the number of shares of Common
Stock beneficially owned by the Holder and its affiliates on an exercise date,
and (ii) the number of shares of Common Stock issuable upon the exercise of this
Warrant with respect to which the determination of this proviso is being made on
an exercise date, which would result in beneficial ownership by the Holder and
its affiliates of more than 4.99% of the outstanding shares of Common Stock of
the Company on such date. For the purposes of the proviso to the immediately
preceding sentence, beneficial ownership shall be determined in accordance with
Section 13(d) of the Securities Exchange Act of 1934, as amended, and Regulation
13d-3 thereunder. Notwithstanding the foregoing, the restriction described in
this paragraph may be revoked upon 75 days prior notice from the Holder to the
Company and is automatically null and void upon an Event of Default under the
Note.

         11. Warrant Agent. The Company may, by written notice to the each
Holder of the Warrant, appoint an agent for the purpose of issuing Common Stock
(or Other Securities) on the exercise of this Warrant pursuant to Section 1,
exchanging this Warrant pursuant to Section 7, and replacing this Warrant
pursuant to Section 8, or any of the foregoing, and thereafter any such
issuance, exchange or replacement, as the case may be, shall be made at such
office by such agent.

         12. Transfer on the Company's Books. Until this Warrant is transferred
on the books of the Company, the Company may treat the registered holder hereof
as the absolute owner hereof for all purposes, notwithstanding any notice to the
contrary.



                                       6
<PAGE>

         13. Notices, Etc. All notices and other communications from the Company
to the Holder of this Warrant shall be mailed by first class registered or
certified mail, postage prepaid, at such address as may have been furnished to
the Company in writing by such Holder or, until any such Holder furnishes to the
Company an address, then to, and at the address of, the last Holder of this
Warrant who has so furnished an address to the Company.

         14. Voluntary Adjustment by the Company. The Company may at any time
during the term of this Warrant reduce the then current Exercise Price to any
amount and for any period of time deemed appropriate by the Board of Directors
of the Company.

         15. Miscellaneous. This Warrant and any term hereof may be changed,
waived, discharged or terminated only by an instrument in writing signed by the
party against which enforcement of such change, waiver, discharge or termination
is sought. This Warrant shall be governed by and construed in accordance with
the laws of State of New York without regard to principles of conflicts of laws.
Except as set forth below in this Section 15, any and all disputes,
controversies and claims that the Company may assert against the any Holder
arising out of or relating to this Warrant shall be determined exclusively by
arbitration (each such arbitration, an "Arbitration") in New York City before a
panel of three neutral arbitrators agreed to by the Purchaser and the Company
(collectively, the "Arbitrators") in accordance with and pursuant to the then
existing commercial arbitration rules of the American Arbitration Association.
The Company hereby irrevocably waives any right to assert such claims in any
other forum. The Arbitrators shall have the power in their discretion to award
specific performance or injunctive relief (but shall not have the power to
render any incidental, special or punitive damages) and reasonable attorneys'
fees and expenses to any party in any arbitration. The Arbitrators may not
change, modify or alter any express condition, term or provision of this Warrant
nor shall they have the power to render any award against any Holder that would
have such effect. Each Arbitration award shall be final and binding upon the
parties subject thereto and judgment may be entered thereon in any court of
competent jurisdiction. The service of any notice, process, motion or other
document in connection with an Arbitration or for the enforcement of any
Arbitration award may be made in the same manner as communications may be given
under Section 13 hereof. Notwithstanding the foregoing, the provisions of this
Section 15 nor any other provision contained in this Warrant shall limit in any
manner whatsoever any Holder's right to commence an action against or in
connection with the Company or its properties in any court of competent
jurisdiction or otherwise utilize judicial process in connection with or arising
out of any Holder's rights and remedies under this Warrant or otherwise (any
such action, a "Court Action"). Court Actions may be brought by any Holder in
any state or federal court of competent jurisdiction and the Company irrevocably
submits to the jurisdiction of such state and federal courts and irrevocably
waives any claim or defense of inconvenient forum or lack of personal
jurisdiction in such forum or right of removal or right to jury trial under any
applicable law or decision or otherwise. Service of any notice, process, motion
or other document in connection with a Court Action may be made in the same
manner as communications may be given under Section 13. In addition, any Holder
may serve process in any other manner permitted under applicable law. The
individuals executing this Warrant on behalf of the Company agree to waive trial
by jury. The prevailing party shall be entitled to recover from the other party
its reasonable attorney's fees and costs. In the event that any provision of
this Warrant is invalid or unenforceable under any applicable statute or rule of
law, then such provision shall be deemed inoperative to the extent that it may
conflict therewith and shall be deemed modified to conform with such statute or
rule of law. Any such provision which may prove invalid or unenforceable under
any law shall not affect the validity or enforceability of any other provision
of this Warrant. The headings in this Warrant are for purposes of reference
only, and shall not limit or otherwise affect any of the terms hereof. The
invalidity or unenforceability of any provision hereof shall in no way affect
the validity or enforceability of any other provision hereof. The Company
acknowledges that legal counsel participated in the preparation of this Warrant
and, therefore, stipulates that the rule of construction that ambiguities are to
be resolved against the drafting party shall not be applied in the
interpretation of this Warrant to favor any party against the other party.
