SEC Reports, the Company has not, in the two years preceding the date hereof,
received notice (written or oral) from any Trading Market to the effect that the
Company is not in compliance with the listing or maintenance requirements
thereof. The Company is, and has no reason to believe that it will not in the
foreseeable future continue to be, in compliance with the listing and
maintenance requirements for continued listing of the Common Stock on the OTC
Bulletin Board. The issuance and sale of the Securities under the Transaction
Documents does not contravene the rules and regulations of the Trading Market on
which the Common Stock is currently listed or quoted or any other Trading Market
with whom the Company may be in formal discussions regarding the listing of the
Common Stock, and no approval of the shareholders of the Company thereunder is
required for the Company to issue and deliver to the Purchasers the maximum
number of Securities contemplated by Transaction Documents.

agreement or understanding with any Purchaser with respect to the transactions
contemplated by the Transaction Documents other than as specified in the
Transaction Documents.

            (x) Disclosure. The Company confirms that neither it nor any Person
acting on its behalf has provided any of the Purchasers or their agents or
counsel with any information that the Company believes constitutes material,
non-public information. The Company understands and confirms that the Purchasers
will rely on the foregoing representations and covenants in effecting
transactions in securities of the Company. All disclosure provided to the
Purchasers regarding the Company, its business and the transactions contemplated
hereby, furnished by or on behalf of the Company (including the Company's
representations and warranties set forth in this Agreement) are true and correct
and do not contain any untrue statement of a material fact or omit to state any
material fact necessary in order to make the statements made therein, in light
of the circumstances under which they were made, not misleading.

hereby, for itself and for no other Purchaser, represents and warrants to the

and performance by such Purchaser of the transactions contemplated by this
Agreement has been duly authorized by all necessary corporate or, if such
Purchaser is not a corporation, such partnership, limited liability company or
other applicable like action, on the part of such Purchaser. Each of this
Agreement and the Registration Rights Agreement has been duly executed by such
Purchaser, and when delivered by such Purchaser in accordance with terms hereof,
will constitute the valid and legally binding obligation of such Purchaser,
enforceable against it in accordance with its terms.

            (b) Investment Intent. Such Purchaser is acquiring the Securities as
principal for its own account for investment purposes only and not with a view
to or for distributing or reselling such Securities or any part thereof, without
prejudice, however, to such Purchaser's right at all times to sell or otherwise
dispose of all or any part of such Securities in compliance with applicable
federal and state securities laws. Subject to the immediately preceding
sentence, nothing contained herein shall be deemed a representation or warranty
by such Purchaser to hold the Securities for any period of time. Such Purchaser
is acquiring the Securities hereunder in the ordinary course of its business.
Such Purchaser does not have any agreement or understanding, directly or
indirectly, with any Person to distribute any of the Securities.

            (c) Purchaser Status. At the time such Purchaser was offered the
Securities, it was, and at the date hereof and as of the Closing Date it is, and
on each date on which it exercises the Warrants it will be, an "accredited
investor" as defined in Rule 501(a) under the Securities Act. Such Purchaser is
not a registered broker-dealer under Section 15 of the Exchange Act.

            (d) General Solicitation. Such Purchaser is not purchasing the
Securities as a result of any advertisement, article, notice or other
communication regarding the Securities published in any newspaper, magazine or
similar media or broadcast over television or radio or presented at any seminar
or any other general solicitation or general advertisement.

            (e) Access to Information. Such Purchaser acknowledges that it has
reviewed the Disclosure Materials and has been afforded (i) the opportunity to
ask such questions as it has deemed necessary of, and to receive answers from,
representatives of the Company concerning the terms and conditions of the
offering of the Shares and the merits and risks of investing in the Securities;
(ii) access to information about the Company and its respective financial
condition, results of operations, business, properties, management and prospects
sufficient to enable it to evaluate its investment; and (iii) the opportunity to
obtain such additional information that the Company possesses or can acquire
without unreasonable effort or expense that is necessary to make an informed
investment decision with respect to the investment. Neither such inquiries nor
any other investigation conducted by or on behalf of such Purchaser or its
representatives or counsel shall modify, amend or affect such Purchaser's right
to rely on the truth, accuracy and completeness of the Disclosure Materials and
the Company's representations and warranties contained in the Transaction
Documents.

            (f) Disclosure. Such Purchaser understands and confirms that the
Company will rely on the foregoing representations and covenants of such
Purchaser in evaluating whether or not registration is required under the
Securities Act for the offer, sale and issuance of the Securities to such
Purchaser as contemplated herein.

The Company acknowledges and agrees that each Purchaser does not make or has not
made any representations or warranties with respect to the transactions
contemplated hereby other than those specifically set forth in this Section 3.2.

                                  ARTICLE IV.
                         OTHER AGREEMENTS OF THE PARTIES

      4.1   (a) Securities may only be disposed of in compliance with state and
federal securities laws. In connection with any transfer of the Securities other
than pursuant to an effective registration statement, to the Company, to an
Affiliate of a Purchaser or in connection with a pledge as contemplated in
Section 4.1(b), the Company may require the transferor thereof to provide to the
Company an opinion of counsel selected by the transferor, the form and substance
of which opinion shall be reasonably satisfactory to the Company, to the effect
that such transfer does not require registration of such transferred Securities
under the Securities Act.

            (b) Certificates evidencing the Securities will contain the
following legend, so long as is required by this Section 4.1(b), with
appropriate inclusion or exclusion of bracketed text depending on whether the
legend is to be applied to a stock certificate or a Warrant:

            [NEITHER THESE SECURITIES NOR THE SECURITIES ISSUABLE UPON EXERCISE
            OF THESE SECURITIES HAVE BEEN REGISTERED] [THESE SECURITIES HAVE NOT
            BEEN REGISTERED]WITH THE SECURITIES AND EXCHANGE COMMISSION OR THE
            SECURITIES COMMISSION OF ANY STATE IN RELIANCE UPON AN EXEMPTION
            FROM REGISTRATION UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE
            "SECURITIES ACT"), AND, ACCORDINGLY, MAY NOT BE OFFERED OR SOLD
            EXCEPT PURSUANT TO AN EFFECTIVE REGISTRATION STATEMENT UNDER THE
            SECURITIES ACT OR PURSUANT TO AN AVAILABLE EXEMPTION FROM, OR IN A
            TRANSACTION NOT SUBJECT TO, THE REGISTRATION REQUIREMENTS OF THE
            SECURITIES ACT AND IN ACCORDANCE WITH APPLICABLE STATE SECURITIES
            LAWS AS EVIDENCED BY A LEGAL OPINION OF COUNSEL TO THE TRANSFEROR TO
            SUCH EFFECT, THE SUBSTANCE OF WHICH SHALL BE REASONABLY ACCEPTABLE
            TO THE COMPANY. [THESE SECURITIES AND THE SECURITIES ISSUABLE UPON
            EXERCISE OF THESE SECURITIES] [THESE SECURITIES] MAY BE PLEDGED IN
            CONNECTION WITH A BONA FIDE MARGIN ACCOUNT SECURED BY SUCH
            SECURITIES.

      4.2 Securities Laws Disclosure; Publicity. On the Closing Date, the
Company shall issue a press release reasonably acceptable to the Purchasers
disclosing the transactions contemplated hereby and file a Current Report on
Form 8-K disclosing the material terms of the transactions contemplated hereby.
In addition, the Company will make such other filings and notices in the manner
and time required by the Commission and the Trading Market on which the Common
Stock is listed. Notwithstanding the foregoing, the Company shall not publicly
disclose the name of any Purchaser, or include the name of any Purchaser in any
filing with the Commission (other than the Registration Statement and any
exhibits to filings made in respect of this transaction in accordance with
periodic filing requirements under the Exchange Act) or any regulatory agency or
Trading Market, without the prior written consent of such Purchaser, which shall
not be unreasonably withheld or delayed, except to the extent such disclosure is
required by law or Trading Market regulations, in which case the Company shall
provide the Purchasers with prior notice of such disclosure.

      4.3 Non-Public Information. The Company covenants and agrees that neither
it nor any other Person acting on its behalf will provide any Purchaser or its
agents or counsel with any information that the Company believes constitutes
material non-public information, unless prior thereto such Purchaser shall have
executed a written agreement regarding the confidentiality and use of such
information. The Company understands and confirms that each Purchaser shall be
relying on the foregoing representations in effecting transactions in securities
of the Company.

                                   ARTICLE V.

manner, by such Person.

      5.4 Amendments; Waivers. No provision of this Agreement may be waived or
amended except in a written instrument signed, in the case of an amendment, by
the Company and each of the Purchasers or, in the case of a waiver, by the party
against whom enforcement of any such waiver is sought. No waiver of any default
with respect to any provision, condition or requirement of this Agreement shall
be deemed to be a continuing waiver in the future or a waiver of any subsequent
default or a waiver of any other provision, condition or requirement hereof, nor
shall any delay or omission of either party to exercise any right hereunder in
any manner impair the exercise of any such right.

      5.5 Construction. The headings herein are for convenience only, do not
constitute a part of this Agreement and shall not be deemed to limit or affect
any of the provisions hereof. The language used in this Agreement will be deemed
to be the language chosen by the parties to express their mutual intent, and no
rules of strict construction will be applied against any party. This Agreement
shall be construed as if drafted jointly by the parties, and no presumption or
burden of proof shall arise favoring or disfavoring any party by virtue of the
authorship of any provisions of this Agreement or any of the Transaction
Documents.

      5.6 Successors and Assigns. This Agreement shall be binding upon and inure
to the benefit of the parties and their successors and permitted assigns. The
Company may not assign this Agreement or any rights or obligations hereunder
without the prior written consent of the Purchasers. Any Purchaser may assign
any or all of its rights under this Agreement to any Person to whom such
Purchaser assigns or transfers any Securities, provided such transferee agrees

      5.7 No Third-Party Beneficiaries. This Agreement is intended for the
benefit of the parties hereto and their respective successors and permitted
assigns and is not for the benefit of, nor may any provision hereof be enforced
by, any other Person, except as otherwise set forth in Section 4.6.

      5.8 Governing Law. All questions concerning the construction, validity,
enforcement and interpretation of this Agreement shall be governed by and
construed and enforced in accordance with the internal laws of the State of New
York, without regard to the principles of conflicts of law thereof. Each party
agrees that all Proceedings concerning the interpretations, enforcement and
defense of the transactions contemplated by this Agreement and any other
Transaction Documents (whether brought against a party hereto or its respective
Affiliates, employees or agents) shall be commenced exclusively in the state and
federal courts sitting in the City of New York, Borough of Manhattan (the "New
York Courts"). Each party hereto hereby irrevocably submits to the exclusive
jurisdiction of the New York Courts 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 the any of the
Transaction Documents), and hereby irrevocably waives, and agrees not to assert
in any Proceeding, any claim that it is not personally subject to the
jurisdiction of any such New York Court, or that such Proceeding has been
commenced in an improper or inconvenient forum. Each party hereto hereby
irrevocably waives personal service of process and consents to process being
served in any such 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 Agreement 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 Agreement or the transactions contemplated hereby. If either party shall
commence a Proceeding to enforce any provisions of a Transaction Document, then
the prevailing party in such Proceeding shall be reimbursed by the other party
for its attorney's fees and other costs and expenses incurred with the
investigation, preparation and prosecution of such Proceeding.

      5.9 Survival. The representations, warranties, agreements and covenants
contained herein shall survive the Closing Date and the delivery of the
applicable Securities.

      5.10 Execution. This Agreement may be executed in two or more
counterparts, all of which when taken together shall be considered one and the
same agreement and shall become effective when counterparts have been signed by
each party and delivered to the other party, it being understood that both
parties need not sign the same counterpart. In the event that any signature is
delivered by facsimile transmission, such signature shall create a valid and
binding obligation of the party executing (or on whose behalf such signature is
executed) with the same force and effect as if such facsimile signature page
were an original thereof.


                                      -15-
<PAGE>

      5.11 Severability. If any provision of this Agreement is held to be
invalid or unenforceable in any respect, the validity and enforceability of the
remaining terms and provisions of this Agreement shall not in any way be
affected or impaired thereby and the parties will attempt to agree upon a valid
and enforceable provision that is a reasonable substitute therefor, and upon so
agreeing, shall incorporate such substitute provision in this Agreement.

      5.12 Rescission and Withdrawal Right. Notwithstanding anything to the
contrary contained in (and without limiting any similar provisions of) the
Transaction Documents, whenever any Purchaser exercises a right, election,
demand or option under a Transaction Document and the Company does not timely
perform its related obligations within the periods therein provided, then such
Purchaser may rescind or withdraw, in its sole discretion from time to time upon
written notice to the Company, any relevant notice, demand or election in whole
or in part without prejudice to its future actions and rights.

      5.13 Replacement of Securities. If any certificate or instrument
evidencing any Securities is mutilated, lost, stolen or destroyed, the Company
shall issue or cause to be issued in exchange and substitution for and upon
cancellation thereof, or in lieu of and substitution therefor, a new certificate
or instrument, but only upon receipt of evidence reasonably satisfactory to the
Company of such loss, theft or destruction and customary and reasonable
indemnity, if requested. The applicants for a new certificate or instrument
under such circumstances shall also pay any reasonable third-party costs
associated with the issuance of such replacement Securities. If a replacement
certificate or instrument evidencing any Securities is requested due to a
mutilation thereof, the Company may require delivery of such mutilated
certificate or instrument as a condition precedent to any issuance of a
replacement.

      5.14 Remedies. In addition to being entitled to exercise all rights
provided herein or granted by law, including recovery of damages, each of the
Purchasers and the Company will be entitled to specific performance under the
Transaction Documents. The parties agree that monetary damages may not be
adequate compensation for any loss incurred by reason of any breach of
obligations described in the foregoing sentence and hereby agrees to waive in
any action for specific performance of any such obligation the defense that a
remedy at law would be adequate.

      5.15 Payment Set Aside. To the extent that the Company makes a payment or
payments to any Purchaser pursuant to any Transaction Document or a Purchaser
enforces or exercises its rights thereunder, and such payment or payments or the
proceeds of such enforcement or exercise or any part thereof are subsequently
invalidated, declared to be fraudulent or preferential, set aside, recovered
from, disgorged by or are required to be refunded, repaid or otherwise restored
to the Company, a trustee, receiver or any other person under any law
(including, without limitation, any bankruptcy law, state or federal law, common
law or equitable cause of action), then to the extent of any such restoration
the obligation or part thereof originally intended to be satisfied shall be
revived and continued in full force and effect as if such payment had not been
made or such enforcement or setoff had not occurred.

      5.16 Independent Nature of Purchasers' Obligations and Rights. The
obligations of each Purchaser under any Transaction Document are several and not
joint with the obligations of any other Purchaser, and no Purchaser shall be
responsible in any way for the performance of the obligations of any other
Purchaser under any Transaction Document. Nothing contained herein or in any
Transaction Document, and no action taken by any Purchaser pursuant thereto,
shall be deemed to constitute the Purchasers as a partnership, an association, a
joint venture or any other kind of entity, or create a presumption that the
Purchasers are in any way acting in concert or as a group with respect to such
obligations or the transactions contemplated by the Transaction Document. Each
Purchaser shall be entitled to independently protect and enforce its rights,
including without limitation the rights arising out of this Agreement or out of
the other Transaction Documents, and it shall not be necessary for any other
Purchaser to be joined as an additional party in any proceeding for such
purpose.
