the foregoing and subject to applicable law, upon the occurrence of a default by
the Borrower or any guarantor involving bankruptcy, insolvency, receivership

warranties made herein shall survive the execution of this Amendment.

         COUNTERPARTS. This Amendment may be signed in any number of
counterparts, each of which shall be considered an original, but when taken
together shall constitute one document.

         AUTHORIZATION. The Borrower represents and warrants that the execution
delivery and performance of this Amendment and the documents referenced herein
are within the authority of the Borrower and have been duly authorized by all
necessary action.

         TRANSFERABLE RECORD. The agreement and note, as amended, is a

Warrant Shares is issued upon exercise of this Warrant shall for all purposes be
deemed to have become the holder of record of such Warrant Shares on the date on
which the Warrant was surrendered and payment of the Exercise Price and any
applicable taxes was made, irrespective of the date of delivery of such
certificate, except that, if the date of such surrender and payment is a date
when the stock transfer books of the Company are closed, such person shall be
deemed to have become the holder of such Warrant Shares at the close of business
on the next succeeding date on which the stock transfer books are open.

         (b) The Company shall, upon request of the Holder, use its best efforts
to deliver Warrant Shares hereunder electronically through the facilities of The
Depository Trust Corporation or another established clearing corporation
performing similar functions.

         (c) For purposes of this agreement, "TRADING DAY" means: (i) any day on
which the Common Stock is listed and traded on the American Stock Exchange
("AMEX"), or (ii) if the Common Stock is not then listed and traded on AMEX,
then a day on which trading occurs on any of the New York Stock Exchange or any
market which is a part of the Nasdaq Stock Market (each, an "ELIGIBLE MARKET")
(or any successor thereto), or (iii) if trading ceases to occur on an Eligible
Market (or any successor thereto), any day other than Saturday, Sunday or other
day on which commercial banks in New York City are authorized or required by law
to remain closed.

         (c) In addition to any other rights available to a Holder, if the
Company fails to deliver to the Holder a certificate representing Warrant Shares
by the third (3rd) Trading Day after the date on which delivery of such
certificate is required by this Warrant, and if after such third (3rd) Trading
Day the Holder purchases (in an open market transaction or otherwise) shares of
Common Stock to deliver in satisfaction of a bona fide sale by the Holder of the
Warrant Shares that the Holder anticipated receiving from the Company (a
"BUY-IN"), then the Company shall, within three (3) Trading Days after the
Holder's request and in the Holder's discretion, either: (i) pay cash to the
Holder in an amount equal to the closing price of the Common Stock, as listed on
the OTC Bulletin Board or any national exchange on which the Common Stock is
then listed (the "Closing Price"), on the date of such purchase by the Holder
(plus brokerage commissions, if any) for the shares of Common Stock so purchased
less the Exercise Price (the "BUY-IN PRICE"), at which point the Company's
obligation to deliver such certificate (and to issue such Common Stock) shall
terminate, or (ii) promptly honor its obligation to deliver to the Holder a
certificate or certificates representing such Common Stock and pay cash to the
Holder in an amount equal to the excess (if any) of the Buy-In Price over the
product of: (A) such number of shares of Common Stock, times (B) the Closing
Price on the date of the event giving rise to the Company's obligation to
deliver such certificate.

         (d) The Company's obligations to issue and deliver Warrant Shares in
accordance with the terms hereof are absolute and unconditional upon
satisfaction by the Holder of the conditions to exercise this Warrant set forth
in sub-section (a) above, irrespective of any action or inaction by the Holder
to enforce the same, any waiver or consent with respect to any provision hereof,

                                       2

<PAGE>

the recovery of any judgment against any person or any action to enforce the
same, or any setoff, counterclaim, recoupment, limitation or termination, or any
breach or alleged breach by the Holder or any other person of any obligation to
the Company (other than the Holder's obligations with respect to the exercise
hereof in accordance with sub-section (a) above) or any violation or alleged
violation of law by the Holder or any other person, and irrespective of any
other circumstance which might otherwise limit such obligation of the Company to
the Holder in connection with the issuance of Warrant Shares. Nothing herein
shall limit a Holder's right to pursue any other remedies available to it
hereunder, at law or in equity including, without limitation, a decree of
specific performance and/or injunctive relief with respect to the Company's
failure to timely deliver certificates representing shares of Common Stock upon
exercise of the Warrant as required pursuant to the terms hereof.

SECTION 2. PAYMENT OF EXERCISE PRICE.

         The Holder shall pay the Exercise Price in immediately available funds;
PROVIDED, HOWEVER, that if at any time there is no effective registration
statement registering the issuance of the Warrant Shares or no current
prospectus available for, the resale of the Warrant Shares by the Holder, the
Holder may satisfy its obligation to pay the Exercise Price through a "cashless
exercise," in which event the Company shall issue to the Holder the number of
Warrant Shares determined as follows:

                  X = Y [(A-B)/A]
where:
                  X = the number of Warrant Shares to be issued to the Holder.

                  Y = the number of Warrant Shares with respect to which this
                  Warrant is being exercised.

                  A = the arithmetic average of the Closing Prices for the five
                  Trading Days immediately prior to (but not including) the
                  Exercise Date.

                  B = the Exercise Price.

SECTION 3. ADJUSTMENT OF EXERCISE PRICE. The Exercise Price and number of
Warrant Shares issuable upon exercise of this Warrant are subject to adjustment
from time to time as set forth in this Section 3.

         (a) STOCK DIVIDENDS AND SPLITS. If the Company, at any time while this
Warrant is outstanding: (i) pays a stock dividend on its Common Stock or
otherwise makes a distribution on any class of capital stock that is payable in
shares of Common Stock, (ii) subdivides outstanding shares of Common Stock into
a larger number of shares, or (iii) combines outstanding shares of Common Stock
into a smaller number of shares, then in each such case the Exercise Price shall
be multiplied by a fraction of which the numerator shall be the number of shares
of Common Stock outstanding immediately before such event and of which the
denominator shall be the number of shares of Common Stock outstanding
immediately after such event. Any adjustment made pursuant to clause (i) of this
paragraph shall become effective immediately after the record date for the

                                       3

<PAGE>

determination of stockholders entitled to receive such dividend or distribution,
and any adjustment pursuant to clause (ii) or (iii) of this paragraph shall
become effective immediately after the effective date of such subdivision or
combination.

         (b) FUNDAMENTAL TRANSACTIONS. If, at any time while this Warrant is
outstanding: (i) the Company effects any merger or consolidation of the Company
with or into another person and the Company is not the surviving party, (ii) the
Company effects any sale of all or substantially all of its assets in one or a
series of related transactions, (iii) any tender offer or exchange offer
(whether by the Company or another person) is completed pursuant to which
holders of Common Stock are permitted to tender or exchange their shares for
other securities, cash or property, or (iv) the Company effects any
reclassification of the Common Stock or any compulsory share exchange pursuant
to which the Common Stock is effectively converted into or exchanged for other
securities, cash or property (other than as a result of a subdivision or
combination of shares of Common Stock covered by Section 3(a) above) (in any
such case, a "FUNDAMENTAL TRANSACTION"), then the Holder shall have the right
thereafter to receive, upon exercise of this Warrant, the same amount and kind
of securities, cash or property as it would have been entitled to receive upon
the occurrence of such Fundamental Transaction if it had been, immediately prior
to such Fundamental Transaction, the holder of the number of Warrant Shares then
issuable upon exercise in full of this Warrant (the "ALTERNATE CONSIDERATION").
The aggregate Exercise Price for this Warrant will not be affected by any such
Fundamental Transaction, but the Company shall apportion such aggregate Exercise
Price among the Alternate Consideration in a reasonable manner reflecting the
relative value of any different components of the Alternate Consideration. If
holders of Common Stock are given any choice as to the securities, cash or
property to be received in a Fundamental Transaction, then the Holder shall be
given the same choice as to the Alternate Consideration it receives upon any
exercise of this Warrant following such Fundamental Transaction. In the event of
a Fundamental Transaction, the Company shall or shall cause the successor or
purchasing person, as the case may be, to execute with the Holder a written
agreement providing that:

                  (i)    this Warrant shall thereafter entitle the Holder to
                         purchase the Alternate Consideration in accordance with
                         this Section 3(b),

                  (ii)   in the case of any such successor or purchasing person,
                         upon such consolidation, merger, statutory exchange,
                         combination, sale or conveyance such successor or
                         purchasing person shall be jointly and severally liable
                         with the Company for the performance of all of the
                         Company's obligations under this Warrant and the
                         Placement Agency Agreement, and

                  (iii)  if registration or qualification is required under the
                         Exchange Act or applicable state law for the public
                         resale by the Holder of shares of stock and other
                         securities so issuable upon exercise of this Warrant,
                         all rights applicable to registration of the Common
                         Stock issuable upon exercise of this Warrant shall
                         apply to the Alternate Consideration.

         If, in the case of any Fundamental Transaction, the Alternate
Consideration includes shares of stock, other securities, other property or
assets of a person other than the Company or any such successor or purchasing
person, as the case may be, in such Fundamental Transaction, then the Company

                                       4

<PAGE>

shall cause such written agreement to also be executed by such other person and
to contain such additional provisions to protect the interests of the Holder as
the Board of Directors of the Company shall reasonably consider necessary by
reason of the foregoing. At the Holder's request, any successor to the Company
or surviving entity in such Fundamental Transaction shall issue to the Holder a
new warrant consistent with the foregoing provisions and evidencing the Holder's
right to purchase the Alternate Consideration for the aggregate Exercise Price
upon exercise thereof. The Company shall cause the terms of any agreement
pursuant to which a Fundamental Transaction is effected to include terms
requiring any such successor or surviving entity to comply with the provisions
of this paragraph (c) and insuring that the Warrant (or any such replacement
security) will be similarly adjusted upon any subsequent transaction analogous
to a Fundamental Transaction. If any Fundamental Transaction constitutes or
results in a "Rule 13e-3 transaction" as defined in Rule 13e-3 under the
Exchange Act with respect to the Company in which the consideration issued
consists principally of cash or stock in a non-public company, the Company (or
any such successor or surviving entity) will, upon request of the Holder,
purchase the Warrant from the Holder for a purchase price, payable in cash
within five (5) Trading Days after such request (or, if later, on the effective
date of the Fundamental Transaction), equal to the Black-Scholes value of the
remaining unexercised portion of this Warrant on the date of such request.

         (c) ADJUSTMENTS FOR OTHER DISTRIBUTIONS. In the event the Company shall
declare a distribution payable in securities of other Persons, evidences of
indebtedness issued by the Company or other Persons, assets (excluding cash
dividends or distributions to the holders of Common Stock paid out of current or
retained earnings and declared by the Company's Board of Directors) or options
or rights not referred to in Sections 3(a) or (b), then, in each such case, upon
exercise of this Warrant within ninety (90) days of such distribution, the
Holder shall be entitled to a proportionate share of any such distribution as
though the Holder was the actual record holder of the number of Warrant Shares
as of the record date fixed for the determination of the holders of Common Stock
entitled to receive such distribution.

         (d) CALCULATIONS. All calculations under this Section 3 shall be made
to the nearest cent or rounded up to the nearest whole share, as applicable. The
number of shares of Common Stock outstanding at any given time shall not include
shares owned or held by or for the account of the Company, and the disposition
of any such shares shall be considered an issue or sale of Common Stock.

         (e) NOTICE OF ADJUSTMENTS. Upon the occurrence of each adjustment
pursuant to this Section 3, the Company at its expense will promptly compute
such adjustment in accordance with the terms of this Warrant and prepare a
certificate setting forth such adjustment, including a statement of the adjusted
Exercise Price and adjusted number or type of Warrant Shares or other securities
issuable upon exercise of this Warrant (as applicable), describing the
transactions giving rise to such adjustments and showing in detail the facts
upon which such adjustment is based. Upon written request, the Company will
promptly deliver a copy of each such certificate to the Holder and to the
Company's transfer agent.

                                       5

<PAGE>

SECTION 4. ADJUSTMENT OF WARRANT SHARES.

         Upon each adjustment of the Exercise Price as provided in Section 3,
the Holder shall thereafter be entitled to subscribe for and purchase, at the
Exercise Price resulting from such adjustment, the number of Warrant Shares
equal to the product of (i) the number of Warrant Shares existing prior to such
adjustment and (ii) the quotient obtained by dividing (A) the Exercise Price
existing prior to such adjustment by (B) the new Exercise Price resulting from
such adjustment. No fractional shares of capital stock of the Company shall be
issued as a result of any such adjustment, and any fractional shares resulting
from the computations pursuant to this paragraph shall be rounded up to the
nearest whole share.

SECTION 5. NO STOCKHOLDER RIGHTS.

         This Warrant shall not entitle the Holder hereof to any voting rights
or other rights as a stockholder of the Company.

SECTION 6. COVENANTS OF THE COMPANY

         (a) The Company shall at all times have authorized and reserved, or
shall authorize and reserve, a sufficient number of shares of its Common Stock
to provide for the exercise of the rights represented by this Warrant.

         (b) The Company shall (i) keep a registration statement relating to the
Warrant Shares or their resale continuously effective until the Expiration Date
(including such day), and (ii) have a sufficient number of authorized but
unissued and otherwise unreserved shares of Common Stock available to issue the
Warrant Shares pursuant to a registration statement upon exercise of the
Warrant.

SECTION 7. ASSIGNMENT, TRANSFER OF WARRANT.

         This Warrant may be assigned by the Holder by delivery of a completed
Form of Assignment attached as Exhibit B hereto. This Warrant and all rights
hereunder are transferable, in whole, or in part, at the agency or office of the
Company or at the office of any warrant agent appointed by the Company, by the
Holder hereof in person or by duly authorized attorney, upon surrender of this
Warrant properly endorsed. Each taker and holder of this Warrant, by taking or
holding the same, consents and agrees that this Warrant, when endorsed, in
blank, shall be deemed negotiable, and, when so endorsed the holder hereof may
be treated by the Company and all other persons dealing with this Warrant as the
absolute owner hereof for any purposes and as the person entitled to exercise
the rights represented by this Warrant, or to the transfer hereof on the books
of the Company, any notice to the contrary notwithstanding; but until each
transfer on such books, the Company may treat the registered holder hereof as
the owner hereof for all purposes.

SECTION 8. LOST, STOLEN, MUTILATED OR DESTROYED WARRANT.

         If this Warrant is lost, stolen, mutilated or destroyed, the Company
may, on such terms as to indemnity or otherwise as it may in its discretion
impose (which shall, in the case of a mutilated Warrant, include the surrender
thereof), issue a new Warrant of like denomination and tenor as the Warrant so
lost, stolen, mutilated or destroyed. Any such new Warrant shall constitute an
original contractual obligation of the Company, whether or not the allegedly
lost, stolen, mutilated or destroyed Warrant shall be at any time enforceable by
anyone.

SECTION 9. NOTICES.

         All notices, advices and communications to be given or otherwise made
to any party to this Agreement shall be deemed to be sufficient if contained in
a written instrument delivered in person or by facsimile transmission or duly
sent by first class registered or certified mail, return receipt requested,
postage prepaid, or by overnight courier, or by electronic mail, with a copy
thereof to be sent by mail (as aforesaid) within 24 hours of such electronic
mail, addressed to such party as provided in the [Subscription Agreement]
[Placement Agency Agreement] or to such other address as the party to whom
notice is to be given may have furnished to the other parties hereto in writing
in accordance herewith. Any such notice or communication shall be deemed to have
been delivered and received (i) in the case of personal delivery or delivery by
facsimile transmission, on the date of such delivery, (ii) in the case of
nationally-recognized overnight courier, on the next business day after the date
when sent and (ii) in the case of mailing, on the third business day following
that on which the piece of mail containing such communication is posted. As used

banking institutions in the State of New York are legally closed for business.

SECTION 11. BINDING EFFECT ON SUCCESSORS.

         Subject to the provisions hereof relating to Fundamental Transactions,
this Warrant shall be binding upon any corporation succeeding the Company by
merger, consolidation or acquisition of all or substantially all of the
Company's assets.

SECTION 12. DESCRIPTIVE HEADINGS AND GOVERNING LAW.

         (a) The description headings of the several sections and paragraphs of
this Warrant are inserted for convenience only and do not constitute a part of
this Warrant. This Warrant shall be construed and enforced in accordance with,
and the rights of the parties shall be governed by, the laws of the State of New
York (without giving effect to conflicts of law principles thereof).

         (b) The Company will not, by amendment of its governing documents or
through any reorganization, transfer of assets, consolidation, merger,
dissolution, issue or sale of securities or any other voluntary action, avoid or
seek to avoid the observance or performance of any of the terms of this Warrant,
but will at all times in good faith assist in the carrying out of all such terms
and in the taking of all such action as may be necessary or appropriate in order
to protect the rights of the Holder against impairment. Without limiting the

                                       7

<PAGE>

generality of the foregoing, the Company: (i) will not increase the par value of
any Warrant Shares above the amount payable therefor on such exercise, (ii) will
take all such action as may be reasonably necessary or appropriate in order that
the Company may validly and legally issue fully paid and nonassessable Warrant
Shares on the exercise of this Warrant, and (iii) will not close its shareholder
books or records in any manner which interferes with the timely exercise of this
Warrant.

         (c) EACH PARTY AGREES THAT ALL LEGAL PROCEEDINGS CONCERNING THE
INTERPRETATIONS, ENFORCEMENT AND DEFENSE OF THE TRANSACTIONS CONTEMPLATED BY ANY
OF THE TRANSACTION DOCUMENTS (WHETHER BROUGHT AGAINST A PARTY HERETO OR ITS
RESPECTIVE AFFILIATES, DIRECTORS, OFFICERS, SHAREHOLDERS, EMPLOYEES OR AGENTS)
SHALL BE COMMENCED EXCLUSIVELY IN THE STATE AND FEDERAL COURTS SITTING IN THE
CITY OF NEW YORK, BOROUGH OF MANHATTAN. EACH PARTY HERETO HEREBY IRREVOCABLY
SUBMITS TO THE EXCLUSIVE JURISDICTION OF THE STATE AND FEDERAL COURTS SITTING IN
THE CITY OF NEW YORK, BOROUGH OF MANHATTAN FOR THE ADJUDICATION OF ANY DISPUTE
HEREUNDER OR IN CONNECTION HEREWITH OR WITH ANY TRANSACTION CONTEMPLATED HEREBY
OR DISCUSSED HEREIN (INCLUDING WITH RESPECT TO THE ENFORCEMENT OF ANY OF THIS
WARRANT), AND HEREBY IRREVOCABLY WAIVES, AND AGREES NOT TO ASSERT IN ANY SUIT,
ACTION OR PROCEEDING, ANY CLAIM THAT IT IS NOT PERSONALLY SUBJECT TO THE
JURISDICTION OF ANY SUCH COURT, THAT SUCH SUIT, ACTION OR PROCEEDING IS
IMPROPER. EACH PARTY HERETO HEREBY IRREVOCABLY WAIVES PERSONAL SERVICE OF
PROCESS AND CONSENTS TO PROCESS BEING SERVED IN ANY SUCH SUIT, ACTION OR
PROCEEDING BY MAILING A COPY THEREOF VIA REGISTERED OR CERTIFIED MAIL OR
OVERNIGHT DELIVERY (WITH EVIDENCE OF DELIVERY) TO SUCH PARTY AT THE ADDRESS IN
EFFECT FOR NOTICES TO IT UNDER THIS WARRANT AND AGREES THAT SUCH SERVICE SHALL
CONSTITUTE GOOD AND SUFFICIENT SERVICE OF PROCESS AND NOTICE THEREOF. NOTHING
CONTAINED HEREIN SHALL BE DEEMED TO LIMIT IN ANY WAY ANY RIGHT TO SERVE PROCESS
IN ANY MANNER PERMITTED BY LAW. EACH PARTY HERETO HEREBY IRREVOCABLY WAIVES, TO
THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, ANY AND ALL RIGHT TO TRIAL BY
JURY IN ANY LEGAL PROCEEDING ARISING OUT OF OR RELATING TO THIS WARRANT OR ANY
OF THE TRANSACTION DOCUMENTS OR THE TRANSACTIONS CONTEMPLATED HEREBY OR THEREBY.
IF EITHER PARTY SHALL COMMENCE AN ACTION OR PROCEEDING TO ENFORCE ANY PROVISIONS
OF THIS WARRANT OR ANY TRANSACTION DOCUMENT, THEN THE PREVAILING PARTY IN SUCH
ACTION OR PROCEEDING SHALL BE REIMBURSED BY THE OTHER PARTY FOR ITS REASONABLE
ATTORNEYS FEES AND OTHER REASONABLE COSTS AND EXPENSES INCURRED WITH THE
INVESTIGATION, PREPARATION AND PROSECUTION OF SUCH ACTION OR PROCEEDING.

SECTION 13. FRACTIONAL SHARES.

         No fractional shares shall be issued upon exercise of this Warrant. The
Company shall, in lieu of issuing any fractional share, pay the Holder entitled
to such fraction a sum in cash equal to such fraction multiplied by the then
effective Exercise Price.

SECTION 14. SEVERABILITY.

         In case any one or more of the provisions of this Warrant shall be
invalid or unenforceable in any respect, the validity and enforceability of the
remaining terms and provisions of this Warrant shall not in any way be affected
or impaired thereby and the parties will attempt in good faith to agree upon a
valid and enforceable provision which shall be a commercially reasonable
substitute therefor, and upon so agreeing, shall incorporate such substitute
provision in this Warrant.
