         1.47.    Exercise of Warrant.

                  1.47.1   Number of Shares Issuable upon Exercise. From and

                  (c)      Except as provided in clause (d) below, if the
         Company's Common Stock is not publicly traded, then as the Holder and

         liquidation, dissolution or winding up pursuant to the Company's
         charter, then all amounts to be payable per share to holders of the
         Common Stock pursuant to the charter in the event of such liquidation,
         dissolution or winding up, plus all other amounts to be payable per
         share in respect of the Common Stock in liquidation under the charter,
         assuming for the purposes of this clause (d) that all of the shares of
         Common Stock then issuable upon exercise of the Warrant are outstanding

                  1.347.3  Company Acknowledgment. The Company will, at the time
of the exercise of the Warrant, upon the request of the holder hereof
acknowledge in writing its continuing obligation to afford to such holder any
rights to which such holder shall continue to be entitled after such exercise in
accordance with the provisions of this Warrant. If the holder shall fail to make
any such request, such failure shall not affect the continuing obligation of the
Company to afford to such holder any such rights.

                  1.447.4  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.

         2.48.    Procedure for Exercise.

                  2.148.1  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.

<PAGE>

                  2.148.2  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

         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)

<PAGE>

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

                  3.149.1  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.

                  3.249.2  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").

                  3.349.3  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.

<PAGE>

                  4.50.    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.

                  5.51.    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).

                  6.52.    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.

<PAGE>

                  7.53.    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.

                  8.54.    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.

                  9.55.    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.

                  10.56.   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.

                  11.57.   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.

<PAGE>

                  12.58.   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.

                  13.59.   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.

<PAGE>

                  14.60.   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.
