par value $.005 per share (the "Common Stock") by the Purchaser.

      The parties hereto agree as follows:

                                   ARTICLE I

                  PURCHASE AND SALE OF COMMON STOCK AND WARRANT

            Section 1.1 Purchase and Sale of Common Stock and Warrant.

            (a) Upon the following terms and conditions, the Company shall issue
and sell to the Purchaser, and the Purchaser shall purchase from the Company, an
aggregate of ____________ shares of Common Stock (the "Shares") at a price per
share of $1.80 (the "Per Share Purchase Price") for an aggregate purchase price
of $____________ (the "Purchase Price"). The Company and the Purchaser are
executing and delivering this Agreement in accordance with and in reliance upon
the exemption from securities registration afforded by Section 4(2) of the U.S.
Securities Act of 1933, as amended, and the rules and regulations promulgated
thereunder (the "Securities Act"), including Regulation D ("Regulation D"),
and/or upon such other exemption from the registration requirements of the
Securities Act as may be available with respect to any or all of the investments
to be made hereunder.

            (b) Upon the following terms and conditions and for no additional
consideration, the Purchaser shall be issued a warrant, in substantially the
form attached hereto as Exhibit A (the "Warrant"), to purchase the number of
shares of Common Stock equal to ___________ percent (___%) of the Shares. The
Warrant shall expire five (5) years from the Closing Date and shall have an
exercise price per share equal to the Warrant Price (as defined in the Warrant).
Any shares of Common Stock issuable to the Purchaser upon exercise of the
Warrant (and such shares when issued) are herein referred to as the "Warrant
Shares." The Shares, the Warrant and the Warrant Shares are sometimes
collectively referred to herein as the "Securities."

            Section 1.2 Purchase Price and Closing. In consideration of and in
express reliance upon the representations, warranties, covenants, terms and
conditions of this Agreement, the Company agrees to issue and sell to the
Purchaser and, in consideration of and in express reliance upon the

the Purchaser agrees to purchase the Shares and the Warrant. The closing of the

(the "Closing") at such time and on such date as the Purchaser and the Company
may agree upon (the "Closing Date"), provided, that all of the conditions set
forth in Article IV hereof and applicable to the Closing shall have been
fulfilled or waived in accordance herewith. The Company shall deliver or cause
to be delivered to the Purchaser (i) a certificate registered in the name of the

                                   ARTICLE II

                         REPRESENTATIONS AND WARRANTIES

            Section 2.1 Representations and Warranties of the Company. The
Company hereby represents and warrants to the Purchaser as follows, as of the
date hereof and the Closing Date, except as set forth in the Commission
Documents (as defined in section 2.1(f) hereof) with respect to each subsection
below or on the Schedule of Exceptions attached hereto with each numbered
Schedule corresponding to the section number herein:

            (a) Organization, Good Standing and Power. The Company is a
corporation duly incorporated, validly existing and in good standing under the
laws of the State of New York and has the requisite corporate power to own,
lease and operate its properties and assets and to conduct its business as it is
now being conducted. The Company does not have any Subsidiaries (as defined in
Section 2.1(g)) or own securities of any kind in any other entity except as set
forth on Schedule 2.1(g) hereto. The Company and each such Subsidiary (as
defined in Section 2.1(g)) is duly qualified to do business as a foreign
corporation and is in good standing in every jurisdiction in which the nature of
the business conducted or property owned by it makes such qualification
necessary except for any jurisdiction(s) (alone or in the aggregate) in which
the failure to be so qualified will not have a Material Adverse Effect. For the
purposes of this Agreement, "Material Adverse Effect" means any effect on the
business, results of operations, prospects, assets or condition (financial or
otherwise) of the Company that is material and adverse to the Company and its
Subsidiaries, taken as a whole, and/or any condition, circumstance, or situation
that would prohibit or otherwise materially interfere with the ability of the
Company from entering into and performing any of its obligations under the
Transaction Documents (as defined below) in any material respect.

            (b) Authorization; Enforcement. The Company has the requisite
corporate power and authority to enter into and perform this Agreement, the
Warrant and that certain Registration Rights Agreement by and between the
Company and the Purchaser, dated as of the date hereof, substantially in the
form of Exhibit B attached hereto (the "Registration Rights Agreement" and,
together with this Agreement and the Warrant, the "Transaction Documents") and
to issue and sell the Securities in accordance with the terms hereof and to
complete the transactions contemplated by the Transaction Documents. The
execution, delivery and performance of the Transaction Documents by the Company
and the consummation by it of the transactions contemplated thereby have been
duly and validly authorized by all necessary corporate action, and, except as
set forth on Schedule 2.1(b), no further consent or authorization of the
Company, its Board of Directors or stockholders is required. When executed and
delivered by the Company, each of the Transaction Documents shall constitute a
valid and binding obligation of the Company enforceable against the Company in
accordance with its terms, except as such enforceability may be limited by
applicable bankruptcy, reorganization, moratorium, liquidation, conservatorship,
receivership or similar laws relating to, or affecting generally the enforcement
of, creditors' rights and remedies or by other equitable principles of general
application.

                                       2

            (c) Capitalization. The authorized capital stock of the Company as
of the date hereof is set forth on Schedule 2.1(c) hereto. All of the
outstanding shares of the Common Stock and any other outstanding security of the
Company have been duly and validly authorized and validly issued, fully paid and
nonassessable and were issued in accordance with the registration or
qualification provisions of the Securities Act, or pursuant to valid exemptions
therefrom. Except as set forth in this Agreement and as set forth on Schedule
2.1(c) hereto, no shares of Common Stock or any other security of the Company
are entitled to preemptive rights, registration rights, rights of first refusal
or similar rights and there are no outstanding options, warrants, scrip, rights
to subscribe to, call or commitments of any character whatsoever relating to, or
securities or rights convertible into, any shares of capital stock of the
Company. Furthermore, except as set forth in this Agreement and as set forth on
Schedule 2.1(c) hereto, there are no contracts, commitments, understandings, or
arrangements by which the Company is or may become bound to issue additional
shares of the capital stock of the Company or options, securities or rights
convertible into shares of capital stock of the Company. Except for customary
transfer restrictions contained in agreements entered into by the Company in
order to sell restricted securities or as provided on Schedule 2.1(c) hereto,
the Company is not a party to or bound by any agreement or understanding
granting registration or anti-dilution rights to any person with respect to any
of its equity or debt securities. Except as set forth on Schedule 2.1(c), the
Company is not a party to, and it has no knowledge of, any agreement or
understanding restricting the voting or transfer of any shares of the capital
stock of the Company. Except as disclosed on Schedule 2.1(c), (i) there are no
outstanding debt securities, or other form of material debt of the Company or
any of its Subsidiaries, (ii) there are no contracts, commitments,
understandings, agreements or arrangements under which the Company or any of its
Subsidiaries is required to register the sale of any of their securities under
the Securities Act, (iii) there are no outstanding securities of the Company or
any of its Subsidiaries which contain any redemption or similar provisions, and
there are no contracts, commitments, understandings, agreements or arrangements
by which the Company or any of its Subsidiaries is or may become bound to redeem
a security of the Company or any of its Subsidiaries, (iv) there are no
securities or instruments containing anti-dilution or similar provisions that
will be triggered by the issuance of the Securities, (v) the Company does not
have any stock appreciation rights or "phantom stock" plans or agreements, or
any similar plan or agreement and (vi) as of the date of this Agreement, except
as set forth in filings made with the Commission, to the Company's and each of

Persons beneficially owns (as determined pursuant to Rule 13d-3 promulgated
under the Exchange Act) or has the right to acquire by agreement with or by
obligation binding upon the Company, beneficial ownership of in excess of 5% of
the Common Stock. Any Person with any right to purchase securities of the
Company that would be triggered as a result of the transactions contemplated
hereby or by any of the other Transaction Documents has waived such rights or
the time for the exercise of such rights has passed, except where failure of the
Company to receive such waiver would not have a Material Adverse Effect. Except
as set forth on Schedule 2.1(c), there are no options, warrants or other
outstanding securities of the Company (including, without limitation, any equity
securities issued pursuant to any Company Plan) the vesting of which will be
accelerated by the transactions contemplated hereby or by any of the other
Transaction Documents. Except as set forth in Schedule 2.1(c), none of the
transactions contemplated by this Agreement or by any of the other Transaction
Documents shall cause, directly or indirectly, the acceleration of vesting of
any options issued pursuant the Company's stock option plans.

<PAGE>

            (d) Issuance of Securities. The Shares and the Warrant to be issued

paid and nonassessable and free and clear of all liens, encumbrances and rights
of refusal of any kind and the holders shall be entitled to all rights accorded
to a holder of Common Stock.

            (e) No Conflicts. The execution, delivery and performance of the
Transaction Documents by the Company and the consummation by the Company of the
transactions contemplated hereby and thereby do not and will not (i) violate any
provision of the Company's Certificate of Incorporation (the "Certificate") or
Bylaws (the "Bylaws"), each as amended to date, or any Subsidiary's comparable
charter documents, (ii) conflict with, or constitute a default (or an event
which with notice or lapse of time or both would become a default) under, or
give to others any rights of termination, amendment, acceleration or
cancellation of, any agreement, mortgage, deed of trust, indenture, note, bond,
license, lease agreement, instrument or obligation to which the Company or any
of its Subsidiaries is a party or by which the Company or any of its
Subsidiaries' respective properties or assets are bound, or (iii) result in a
violation of any federal, state, local or foreign statute, rule, regulation,
order, judgment or decree (including federal and state securities laws and
regulations) applicable to the Company or any of its Subsidiaries or by which
any property or asset of the Company or any of its Subsidiaries is bound or
affected, except, in all cases, other than violations pursuant to clauses (i) or
(iii) (with respect to federal and state securities laws) above, except, for
such conflicts, defaults, terminations, amendments, acceleration, cancellations

            (f) Commission Documents, Financial Statements. The Common Stock of
the Company is registered pursuant to Section 12(b) or 12(g) of the Securities

forms, statements and other documents required to be filed by it with the
Securities and Exchange Commission (the "Commission") pursuant to the reporting
requirements of the Exchange Act, including pursuant to Sections 13, 14 or 15(d)
thereof (all of the foregoing and all exhibits included therein and financial

complied in all material respects with the requirements of the Exchange Act and
the rules and regulations of the Commission promulgated thereunder, and the Form
10-Q and Form 10-K at the time of their respective filings did not contain any
untrue statement of a material fact or omit to state a material fact required to
be stated therein or necessary in order to make the statements therein, in light
of the circumstances under which they were made, not misleading. As of their
respective dates, the financial statements of the Company included in the
Commission Documents were complete and correct in all material respects and
complied with applicable accounting requirements and the published rules and
regulations of the Commission or other applicable rules and regulations with
respect thereto. Such financial statements have been prepared in accordance with
accounting principles generally accepted in the United States ("GAAP") applied
on a consistent basis during the periods involved (except (i) as may be
otherwise indicated in such financial statements or the Notes thereto or (ii) in
the case of unaudited interim statements, to the extent they may not include
footnotes or may be condensed or summary statements), and fairly present in all
material respects the financial position of the Company and its Subsidiaries as
of the dates thereof and the results of operations and cash flows for the
periods then ended (subject, in the case of unaudited statements, to normal
year-end audit adjustments).

            (g) Subsidiaries. Schedule 2.1(g) hereto sets forth each Subsidiary

majority of the securities or other ownership interest having ordinary voting
power (absolutely or contingently) for the election of directors or other
persons performing similar functions are at the time owned directly or
indirectly by the Company and/or any of its other Subsidiaries. All of the
outstanding shares of capital stock of each Subsidiary have been duly authorized
and validly issued, and are fully paid and nonassessable. There are no
outstanding preemptive, conversion or other rights, options, warrants or
agreements granted or issued by or binding upon any Subsidiary for the purchase
or acquisition of any shares of capital stock of any Subsidiary or any other
securities convertible into, exchangeable for or evidencing the rights to
subscribe for any shares of such capital stock. Neither the Company nor any
Subsidiary is subject to any obligation (contingent or otherwise) to repurchase
or otherwise acquire or retire any shares of the capital stock of any Subsidiary
or any convertible securities, rights, warrants or options of the type described
in the preceding sentence except as set forth on Schedule 2.1(g) hereto. Neither
the Company nor any Subsidiary is party to, nor has any knowledge of, any
agreement restricting the voting or transfer of any shares of the capital stock
of any Subsidiary.

            (h) No Material Adverse Change. Since June 30, 2005, the Company has
not experienced or suffered any Material Adverse Effect, except as disclosed on
Schedule 2.1(h) hereto.

                                       5
<PAGE>

            (i) No Undisclosed Liabilities. Except as disclosed on Schedule
2.1(i) hereto, since June 30, 2005, neither the Company nor any of its
Subsidiaries has incurred any liabilities, obligations, claims or losses
(whether liquidated or unliquidated, secured or unsecured, absolute, accrued,
contingent or otherwise) other than those incurred in the ordinary course of the
Company's or its Subsidiaries respective businesses or which, individually or in
the aggregate, are not reasonably likely to have a Material Adverse Effect.
Since June 30, 2005, none of the Company or any of its Subsidiaries has
participated in any transaction material to the condition of the Company which
is outside of the ordinary course of its business.

            (j) No Undisclosed Events or Circumstances. Since June 30, 2005,
except as disclosed on Schedule 2.1(j) hereto, no event or circumstance exists
with respect to the Company or its Subsidiaries or their respective businesses,
properties, operations or financial condition, which, under applicable law, rule
or regulation, requires public disclosure or announcement by the Company but
which has not been so publicly announced or disclosed.

            (k) Indebtedness. The Commission Documents or Schedule 2.1(k) hereto
sets forth as of the date hereof all outstanding secured and unsecured
Indebtedness of the Company or any Subsidiary, or for which the Company or any
Subsidiary has commitments. For the purposes of this Agreement, "Indebtedness"
shall mean (a) any liabilities for borrowed money or amounts owed in excess of
$300,000 (other than trade accounts payable incurred in the ordinary course of
business), (b) all guaranties, endorsements and other contingent obligations in
respect of liabilities for borrowed money of others in excess of $100,000,
whether or not the same are or should be reflected in the Company's balance
sheet (or the notes thereto), except guaranties by endorsement of negotiable
instruments for deposit or collection or similar transactions in the ordinary
course of business; and (c) the present value of any lease payments in excess of
$25,000 due under leases required to be capitalized in accordance with GAAP.
Neither the Company nor any Subsidiary is in default with respect to any
Indebtedness.

            (l) Title to Assets. Each of the Company and the Subsidiaries has
good and valid title to all of its real and personal property reflected in the
Commission Documents, free and clear of any mortgages, pledges, charges, liens,
security interests or other encumbrances, except for those indicated on Schedule
2.1(l) hereto or such that, individually or in the aggregate, do not cause a
Material Adverse Effect. All such leases of the Company and each of its
Subsidiaries are valid and subsisting and in full force and effect.

            (m) Actions Pending. There is no action, suit, claim, investigation,
arbitration, alternate dispute resolution proceeding or other proceeding pending
or, to the knowledge of the Company, threatened against the Company or any
Subsidiary which questions the validity of this Agreement or any of the other
Transaction Documents or any of the transactions contemplated hereby or thereby
or any action taken or to be taken pursuant hereto or thereto. Except as set
forth on Schedule 2.1(m) hereto, there is no action, suit, claim, investigation,
arbitration, alternate dispute resolution proceeding or other proceeding pending
or, to the knowledge of the Company, threatened against or involving the
Company, any Subsidiary or any of their respective properties or assets, which
individually or in the aggregate, could reasonably be expected to have a
Material Adverse Effect. There are no outstanding orders, judgments,
injunctions, awards or decrees of any court, arbitrator or governmental or
regulatory body against the Company or any Subsidiary or any officers or
directors of the Company or any Subsidiary in their capacities as such, which
individually or in the aggregate, could reasonably be expected to have a
Material Adverse Effect.

                                       6
<PAGE>

            (n) Compliance with Law. The business of the Company and the
Subsidiaries has been and is presently being conducted in accordance with all
applicable federal, state and local governmental laws, rules, regulations and
ordinances, except as set forth on Schedule 2.1(n) hereto or such that,
individually or in the aggregate, the noncompliance therewith could not
reasonably be expected to have a Material Adverse Effect. The Company and each
of its Subsidiaries have all franchises, permits, licenses, consents and other
governmental or regulatory authorizations and approvals necessary for the
conduct of its business as now being conducted by it unless the failure to
possess such franchises, permits, licenses, consents and other governmental or
regulatory authorizations and approvals, individually or in the aggregate, could
not reasonably be expected to have a Material Adverse Effect.

            (o) Taxes. Except as set forth on Schedule 2.1(o) hereto, the
Company and each of the Subsidiaries has accurately prepared and filed all
federal, state and other tax returns required by law to be filed by it, has paid
all taxes shown to be due and all additional assessments, and adequate
provisions have been and are reflected in the financial statements of the
Company and the Subsidiaries for all current taxes and other charges to which
the Company or any Subsidiary is subject and which are not currently due and
payable. Except as disclosed on Schedule 2.1(o) hereto, none of the federal
income tax returns of the Company or any Subsidiary has been audited by the
Internal Revenue Service. The Company has no knowledge of any additional
assessments, adjustments or contingent tax liability (whether federal or state)
of any nature whatsoever, whether pending or threatened against the Company or
any Subsidiary for any period, nor of any basis for any such assessment,
adjustment or contingency.

            (p) Certain Fees. Except as set forth on Schedule 2.1(p) hereto, the
Company has not employed any broker or finder or incurred any liability for any
brokerage or investment banking fees, commissions, finders' structuring fees,
financial advisory fees or other similar fees in connection with the Transaction
Documents.

            (q) Disclosure. Neither this Agreement or the Schedules hereto nor
any other documents, certificates or instruments furnished to the Purchasers by
or on behalf of the Company or any Subsidiary in connection with the
transactions contemplated by this Agreement contains any untrue statement of a
material fact or omits to state a material fact necessary in order to make the
statements made herein or therein, in the light of the circumstances under which
they were made herein or therein, not misleading.

            (r) Operation of Business. Except as set forth on Schedule 2.1(r)
hereto, the Company and each of the Subsidiaries owns or possesses the rights to
use all patents, trademarks, domain names (whether or not registered) and any

            (s) Environmental Compliance. Except as disclosed on Schedule 2.1(s)
hereto, the Company and each of its Subsidiaries have obtained all material
approvals, authorization, certificates, consents, licenses, orders and permits
or other similar authorizations of all governmental authorities, or from any
other person, that are required under any Environmental Laws. "Environmental
Laws" shall mean all applicable laws relating to the protection of the
environment including, without limitation, all requirements pertaining to
reporting, licensing, permitting, controlling, investigating or remediating
emissions, discharges, releases or threatened releases of hazardous substances,
chemical substances, pollutants, contaminants or toxic substances, materials or
wastes, whether solid, liquid or gaseous in nature, into the air, surface water,
groundwater or land, or relating to the manufacture, processing, distribution,
use, treatment, storage, disposal, transport or handling of hazardous
substances, chemical substances, pollutants, contaminants or toxic substances,
material or wastes, whether solid, liquid or gaseous in nature. Except as set
forth on Schedule 2.1(s) hereto, the Company has all necessary governmental
approvals required under all Environmental Laws and used in its business or in
the business of any of its Subsidiaries, except for such instances as would not
individually or in the aggregate have a Material Adverse Effect. The Company and
each of its Subsidiaries are also in compliance with all other limitations,
restrictions, conditions, standards, requirements, schedules and timetables
required or imposed under all Environmental Laws. Except for such instances as
would not individually or in the aggregate have a Material Adverse Effect, there
are no past or present events, conditions, circumstances, incidents, actions or
omissions relating to or in any way affecting the Company or its Subsidiaries
that violate or would be reasonably likely to violate any Environmental Law
after the Closing or that would be reasonably likely to give rise to any
environmental liability, or otherwise form the basis of any claim, action,
demand, suit, proceeding, hearing, study or investigation (i) under any
Environmental Law or (ii) based on or related to the manufacture, processing,
distribution, use, treatment, storage (including, without limitation,
underground storage tanks), disposal, transport or handling, or the emission,
discharge, release or threatened release of any hazardous substance.

            (t) Books and Records; Internal Accounting Controls. The records and
documents of the Company and its Subsidiaries accurately reflect in all material
respects the information relating to the business of the Company and its
Subsidiaries, the location and collection of their assets, and the nature of all
transactions giving rise to the obligations or accounts receivable of the
Company or any Subsidiary. The Company and each of its Subsidiaries maintain a
system of internal accounting controls sufficient to provide reasonable
assurance that (i) transactions are executed in accordance with management's
general or specific authorizations, (ii) transactions are recorded as necessary
to permit preparation of financial statements in conformity with GAAP and to
maintain asset accountability, (iii) access to assets is permitted only in
accordance with management's general or specific authorization, (iv) the
recorded accountability for assets is compared with the existing assets at
reasonable intervals and appropriate actions are taken with respect to any
differences and (v) accounts, notes and other receivables and inventory are
recorded accurately, and proper and adequate procedures are implemented to
effect the collection thereof on a current and timely basis. Except as set forth
on Schedule 2.1(t) hereto, there are no significant deficiencies or material
weaknesses in the design or operation of internal controls over financial
reporting that would reasonably be expected to adversely affect the Company's
ability to record, process, summarize and report financial information, and
there is no fraud, whether or not material, that involves management or, to the
knowledge of the Company, other employees who have a significant role in the
Company's internal controls and the Company has provided to the Purchaser copies
of any written materials relating to the foregoing.

            (u) Material Agreements. Except for the Transaction Documents (with
respect to clause (i) of this Section 2.1(u) only) or as would not be reasonably
likely to have a Material Adverse Effect, (i) the Company and each of its
Subsidiaries have performed all obligations required to be performed by them to
date under any written or oral contract, instrument, agreement, commitment,
obligation, plan or arrangement, filed or required to be filed with the
Commission (the "Material Agreements"), (ii) neither the Company nor any of its

customers or suppliers on the one hand, and (b) on the other hand, any officer,
employee, consultant or director of the Company, or any of its Subsidiaries, or
any person owning any capital stock of the Company or any Subsidiary or any
member of the immediate family of such officer, employee, consultant, director
or stockholder or any corporation or other entity controlled by such officer,
employee, consultant, director or stockholder, or a member of the immediate
family of such officer, employee, consultant, director or stockholder which, in
each case, is required to be disclosed in the Commission Documents or in the
Company's most recently filed definitive proxy statement on Schedule 14A, that

all applicable federal and state securities laws in connection with the offer,
issuance and sale of the Securities hereunder. Neither the Company nor anyone
acting on its behalf, directly or indirectly, has or will sell, offer to sell or
solicit offers to buy any of the Securities or similar securities to, or solicit
offers with respect thereto from, or enter into any negotiations relating
thereto with, any person, or has taken or will take any action so as to bring
the issuance and sale of any of the Securities under the registration provisions
of the Securities Act and applicable state securities laws, and neither the
Company nor any of its affiliates, nor any person acting on its or their behalf,
has engaged in any form of general solicitation or general advertising (within
the meaning of Regulation D under the Securities Act) in connection with the
offer or sale of any of the Securities.

            (x) Governmental Approvals. Except as set forth on Schedule 2.1(x)
hereto, and except for the filing of any notice prior or subsequent to the
Closing that may be required under applicable state and/or federal securities
laws (which if required, shall be filed on a timely basis), no authorization,
consent, approval, license, exemption of, filing or registration with any court
or governmental department, commission, board, bureau, agency or
instrumentality, domestic or foreign, is or will be necessary for, or in
connection with, the execution or delivery of the Securities, or for the
performance by the Company of its obligations under the Transaction Documents.

Subsidiary has any collective bargaining arrangements or agreements covering any

individually or in the aggregate, would be reasonably likely to have a Material
Adverse Effect, has terminated or, to the knowledge of the Company, has any

Material Adverse Effect, (i) neither the Company nor any of its Subsidiaries is

            (aa) ERISA. No liability to the Pension Benefit Guaranty Corporation
has been incurred with respect to any Plan by the Company or any of its
Subsidiaries which is or would be materially adverse to the Company and its
Subsidiaries. The execution and delivery of this Agreement and the issuance and
sale of the Securities will not involve any transaction which is subject to the
prohibitions of Section 406 of the Employee Retirement Income Security Act of
1974, as amended ("ERISA") or in connection with which a tax could be imposed
pursuant to Section 4975 of the Internal Revenue Code of 1986, as amended. As

            (bb) Independent Nature of Purchaser. The Company acknowledges that
the obligations of the Purchaser under the Transaction Documents are several and
not joint with the obligations of any third party purchaser of the Company's
securities, and the Purchaser shall not be responsible in any way for the
performance of the obligations of any third party purchaser of the Company's
securities. The Company acknowledges that the decision of the Purchaser to
purchase Securities pursuant to the Transaction Documents has been made by the
Purchaser independently of any third party purchaser of the Company's
securities. The Company acknowledges that nothing contained herein or in any
other Transaction Document or any agreement of any such third party purchaser,
and no action taken by the Purchaser pursuant to any of the Transaction
Documents or any such third party purchaser pursuant thereto, shall be deemed to
constitute the Purchaser and any third party purchaser of the Company's
securities as a partnership, an association, a joint venture or any other kind
of entity or group, or create a presumption that the Purchaser and any such
third party purchaser of the Company's securities are in any way acting in
concert or as a group with respect to any matters. To the extent that any such
third party purchasers purchase the same or similar securities as the Purchaser
hereunder or on the same or similar terms and conditions or pursuant to the same
or similar documents, all such matters are solely in the control of the Company,
not the action or decision of the Purchaser, and would be solely for the
convenience of the Company.

            (cc) Anti-takeover Device. Neither the Company nor any of its
Subsidiaries has any outstanding shareholder rights plan or "poison pill" or any
similar arrangement. There are no provisions of any anti-takeover or business
combination statute applicable to the Company, the Certificate of Incorporation
and the Bylaws which would preclude the issuance and sale of the Securities, the
reservation for issuance of the Warrant Shares and the consummation of the other
transactions contemplated by this Agreement or any of the other Transaction
Documents.

            (dd) No Integrated Offering. Neither the Company, nor any of its
affiliates, nor any person acting on its or their behalf, has directly or
indirectly made any offers or sales of any security or solicited any offers to
buy any security under circumstances that would cause the offering of the
Securities pursuant to this Agreement to be integrated with prior offerings by
the Company for purposes of the Securities Act which would prevent the Company
from selling the Securities pursuant to Regulation D and Rule 506 thereof under
the Securities Act, or any applicable exchange-related stockholder approval
provisions, nor will the Company or any of its affiliates or subsidiaries take
any action or steps that would cause the offering of the Securities to be
integrated with other offerings if such other offering, if integrated, would
cause the offer and sale of the Securities not to be exempt from registration
pursuant to Regulation D and Rule 506 thereof under the Securities Act. The
Company does not have any registration statement pending before the Commission
or currently under the Commission's review and except as set forth on Schedule
2.1(dd) hereto, since November 1, 2005, the Company has not offered or sold any
of its equity securities or debt securities convertible into shares of Common
Stock.

            (ee) Sarbanes-Oxley Act(ff) . The Company is in compliance with the
applicable provisions of the Sarbanes-Oxley Act of 2002 (the "Sarbanes-Oxley
Act"), and the rules and regulations promulgated thereunder, that are effective
and for which compliance by the Company is required as of the date hereof and
intends to comply with other applicable provisions of the Sarbanes-Oxley Act,
and the rules and regulations promulgated thereunder, upon the effectiveness of
such provisions or the date by which compliance therewith by the Company is
required.

            (gg) Delisting Notification. Since November 9, 2005, the Company has
not received notice (written or oral) from the Nasdaq Capital Market to the
effect that the Company is not in compliance with the listing or maintenance
requirements of such market and the Company has no reason to believe that it
will be delisted in the foreseeable future.

            (hh) Investment Company Act Status. The Company is not, and as a
result of and immediately upon the Closing will not be, an "investment company"
or a company "controlled" by an "investment company," within the meaning of the
Investment Company Act of 1940, as amended.

            Section 2.2 Representations and Warranties of the Purchasers. The
Purchaser hereby represents and warrants to the Company as follows as of the
date hereof and as of the Closing Date:

corporation duly incorporated, validly existing and in good standing under the
laws of the jurisdiction of its organization.

            (b) Authorization and Power. The Purchaser has the requisite power
and authority to enter into and perform the Transaction Documents and to
purchase the Securities being sold to it hereunder. The execution, delivery and
performance of the Transaction Documents by the Purchaser and the consummation
by it of the transactions contemplated hereby have been duly authorized by all
necessary corporate action, and no further consent or authorization of the
Purchaser or its Board of Directors or stockholders is required. When executed
and delivered by the Purchaser, the other Transaction Documents shall constitute
valid and binding obligations of the Purchaser enforceable against the Purchaser
in accordance with their terms, except as such enforceability may be limited by
applicable bankruptcy, insolvency, reorganization, moratorium, liquidation,
conservatorship, receivership or similar laws relating to, or affecting
generally the enforcement of, creditor's rights and remedies or by other
equitable principles of general application.

            (c) No Conflict. The execution, delivery and performance of the
Transaction Documents by the Purchaser and the consummation by the Purchaser of
the transactions contemplated thereby and hereby do not and will not (i) violate
any provision of the Purchaser's charter or organizational documents, (ii)
conflict with, or constitute a default (or an event which with notice or lapse
of time or both would become a default) under, or give to others any rights of
termination, amendment, acceleration or cancellation of, any agreement,
mortgage, deed of trust, indenture, note, bond, license, lease agreement,
instrument or obligation to which the Purchaser is a party or by which the
Purchaser's properties or assets are bound, or (iii) result in a violation of
any federal, state, local or foreign statute, rule, regulation, order, judgment
or decree (including federal and state securities laws and regulations)
applicable to the Purchaser or by which any property or asset of the Purchaser
are bound or affected, except, in all cases, other than violations pursuant to
clauses (i) or (iii) (with respect to federal and state securities laws) above,
for such conflicts, defaults, terminations, amendments, accelerations,
cancellations and violations as would not, individually or in the aggregate,
materially and adversely affect the Purchaser's ability to perform its
obligations under the Transaction Documents.

            (d) Acquisition for Investment. The Purchaser is purchasing the
Shares and Warrant and will purchase the Warrant Shares solely for its own
account for the purpose of investment and not with a view to or for sale in
connection with distribution. The Purchaser does not have a present intention to
sell any of the Shares, the Warrant or Warrant Shares, nor a present arrangement
(whether or not legally binding) or intention to effect any distribution of any
of the Shares, the Warrant or the Warrant Shares to or through any person or
entity; provided, however, that by making the representations herein, the
Purchaser does not agree to hold the Shares, the Warrant or the Warrant Shares
for any minimum or other specific term and reserves the right to dispose of the
Shares, the Warrant or the Warrant Shares at any time in accordance with Federal
and state securities laws applicable to such disposition. The Purchaser
acknowledges that it (i) has such knowledge and experience in financial and
business matters such that the Purchaser is capable of evaluating the merits and
risks of the Purchaser's investment in the Company, (ii) is able to bear the
financial risks associated with an investment in the Securities, (iii) has been
given full access to such records of the Company and the Subsidiaries and to the
officers of the Company and the Subsidiaries as it has deemed necessary or
appropriate to conduct its due diligence investigation and (iv) has reviewed or
has had the opportunity to review the Commission Documents and any other filings
made by the Company with the Commission which are available to the public by
accessing the Commission's website at http://www.sec.gov, including the risk
factors set forth in the Commission Documents.

            (e) Rule 144. The Purchaser understands that the Securities must be
held indefinitely unless such Securities are registered under the Securities Act
or an exemption from registration is available. The Purchaser acknowledges that
it is familiar with Rule 144 of the rules and regulations of the Commission, as
amended, promulgated pursuant to the Securities Act ("Rule 144"), and that the
Purchaser has been advised that Rule 144 permits resales only under certain
circumstances. The Purchaser understands that to the extent that Rule 144 is not
available, the Purchaser will be unable to sell any Securities without either
registration under the Securities Act or the existence of another exemption from
such registration requirement.

      t 12 (f) General. The purchaser understands that the Securities are being
offered and sold in reliance on a transactional exemption from the registration
requirements of federal and state securities laws and the Company is relying
upon the truth and accuracy of the representations, warranties, agreements,
acknowledgments and understandings of the Purchaser set forth herein in order to
determine the applicability of such exemptions and the suitability of the
Purchaser to acquire the Securities. The Purchaser understands that no United
States federal or state agency or any government or governmental agency has
passed upon or made any recommendation or endorsement of the Securities.

            (g) No General Solicitation. The Purchaser acknowledges that the
Securities were not offered to the Purchaser by means of any advertisement,
article, notice or other communication published in any newspaper, magazine, or
similar media, or broadcast over television or radio, or any seminar or meeting
to which the Purchaser was invited by any of the foregoing means of
communications.

                                       14
<PAGE>

            (h) Accredited Investor. The Purchaser is an "accredited investor"
(as defined in Rule 501 of Regulation D), and the Purchaser has such experience
in business and financial matters that it is capable of evaluating the merits
and risks of an investment in the Securities. The Purchaser is not required to
be registered as a broker-dealer under Section 15 of the Exchange Act and the
Purchaser is not a broker-dealer. The Purchaser acknowledges that an investment
in the Securities is speculative and involves a high degree of risk. The
Purchaser has completed or caused to be completed the Stock Certificate and
Warrant Questionnaire and the Registration Statement/Suitability Questionnaire
attached hereto as Exhibit C and Exhibit D, respectively. The Purchaser
understands that the Company is relying upon the truth and accuracy of such
information set forth in the Registration Statement/Suitability Questionnaire to
determine the suitability of the Purchaser to acquire the Securities.

            (i) Certain Fees. The Purchaser has not employed any broker or
finder or incurred any liability for any brokerage or investment banking fees,
commissions, finders' structuring fees, financial advisory fees or other similar
fees in connection with the Transaction Documents.

            (j) Independent Investment. The Purchaser has not agreed to act with
any third party purchaser of the Company's securities for the purpose of
acquiring, holding, voting or disposing of the Securities purchased hereunder
for purposes of Section 13(d) under the Exchange Act, and the Purchaser is
acting independently with respect to its investment in the Securities.

            (k) Prohibited Transactions. During the thirty (30) days preceding
the date hereof, neither the Purchaser nor any affiliate of the Purchaser,
foreign or domestic, has, directly or indirectly, effected or agreed to effect
any Short Sale (as defined below), whether or not against the box, established
any "put equivalent position" (as defined in Rule 16a-1(h) under the 1934 Act)
with respect to the Common Stock, borrowed or pre-borrowed any shares of Common
Stock, or granted any other right (including, without limitation, any put or
call option) with respect to the Common Stock or with respect to any security
that includes, relates to or derived any significant part of its value from the
Common Stock or otherwise sought to hedge its position in the Securities (each,
a "Prohibited Transaction"). Prior to the earliest to occur of (i) the
termination of this Agreement, (ii) the effective date of the Registration
Statement (as defined in the Registration Rights Agreement) or (iii) the
Effectiveness Date (as defined in the Registration Rights Agreement), the
Purchaser shall not, and shall cause its affiliates not to, engage, directly or
indirectly, in (a) a Prohibited Transaction nor (b) any sale, assignment,
pledge, hypothecation, put, call, or other transfer of any of the shares of
Common Stock, the Warrant or other securities of the Company acquired hereunder.
For purposes hereof, "Short Sale" shall mean all "short sales" as defined in
Rule 200 of Regulation SHO under the Exchange Act.

            Section 3.3 Inspection Rights. The Company shall permit, during
normal business hours and upon reasonable request and reasonable notice, the
Purchaser or any employees, agents or representatives thereof, so long as the
Purchaser shall be obligated hereunder to purchase the Shares or shall
beneficially own any Shares or Warrant Shares, which in the aggregate, represent
more than two percent (2%) of the total combined voting power of all voting
securities of the Company then outstanding, for purposes reasonably related to
the Purchaser's interests as a stockholder to examine and make reasonable copies
of the records and books of account of, and visit and inspect the properties,
assets, operations and business of the Company and any Subsidiary, and to
discuss the affairs, finances and accounts of the Company and any Subsidiary
with any of its officers, consultants, directors, and key employees.

            Section 3.4 Compliance with Laws. The Company shall comply, and
cause each Subsidiary to comply, with all applicable laws, rules, regulations
and orders, noncompliance with which would be reasonably likely to have a
Material Adverse Effect.

            Section 3.5 Keeping of Records and Books of Account. The Company
shall keep and cause each Subsidiary to keep adequate records and books of
account, in which complete entries will be made in accordance with GAAP
consistently applied, reflecting all financial transactions of the Company and

            (a) Quarterly Reports filed with the Commission on Form 10-Q;

            (b) Annual Reports filed with the Commission on Form 10-K; and

            (c) Copies of all notices, information and proxy statements in

            Section 3.7 Other Agreements. The Company shall not enter into any
agreement in which the terms of such agreement would restrict or impair the
right or ability of the Company or any Subsidiary to perform its obligations
under any Transaction Document.

            Section 3.8 Use of Proceeds. The net proceeds from the sale of the
Shares will be used by the Company for working capital and general corporate
purposes and not to redeem any Common Stock or securities convertible,
exercisable or exchangeable into Common Stock or to settle any outstanding
litigation.

            Section 3.9 Reporting Status; Form S-3 Eligibility. So long as the
Purchaser beneficially owns any of the Securities, the Company shall timely file
all reports required to be filed with the Commission pursuant to the Exchange
Act, and the Company shall not terminate its status as an issuer required to
file reports under the Exchange Act even if the Exchange Act or the rules and
regulations thereunder would permit such termination. Subject to the terms of
the Transaction Documents, the Company further covenants that it will take such
further action as the Purchaser may reasonably request, all to the extent
required from time to time to enable the Purchaser to sell the Securities
without registration under the Securities Act within the limitation of the
exemptions provided by Rule 144 promulgated under the Securities Act. Upon the
request of the Purchaser, the Company shall deliver to the Purchaser a written
certification of a duly authorized officer as to whether it has complied with
such requirements. The Company currently meets, and will use its best efforts to
take all necessary action to continue to meet, the "registrant eligibility"
requirements set forth in the general instructions to Form S-3 applicable to
"resale" registrations on Form S-3 during the Effectiveness Period (as defined
in the Registration Rights Agreement).

            Section 3.10 Disclosure of Transaction. The Company shall issue a
press release describing the material terms of the transactions contemplated
hereby (the "Press Release") as soon as practicable after the Closing Date but
in no event later than one hour after the Closing; provided, however, that if
the Closing occurs after 4:00 P.M. Eastern Time on any Trading Day, the Company
shall issue the Press Release no later than 9:00 A.M. Eastern Time on the first
Trading Day following the Closing Date. The Company shall also file with the
Commission a Current Report on Form 8-K (the "Form 8-K") describing the material
terms of the transactions contemplated hereby (and attaching as exhibits thereto
this Agreement, the Registration Rights Agreement, the form of Warrant and the
Press Release) as soon as practicable following the Closing Date but in no event
more than two (2) Trading Days following the Closing Date, which Press Release
and Form 8-K shall be subject to prior review and comment by the Purchaser.
"Trading Day" means any day during which the Nasdaq Capital Market (or other
principal exchange on which the Common Stock is traded) shall be open for
trading.

            Section 3.11 Disclosure of Material Information. The Company
covenants and agrees that neither it nor any other person acting on its behalf
has provided or will provide the Purchaser or any of its agents or counsel with
any information that the Company believes constitutes material non-public
information, unless prior thereto the Purchaser shall have executed a written
agreement regarding the confidentiality and use of such information. The Company
understands and confirms that the Purchaser shall be relying on the foregoing
representations in effecting transactions in securities of the Company.

            Section 3.12 Form D. The Company agrees to file a Form D with
respect to the Securities as required by Rule 506 under Regulation D and to

            Section 3.13 No Integrated Offerings. The Company shall not make any
offers or sales of any security (other than the Securities being offered or sold
hereunder) under circumstances that would require registration of the Securities
being offered or sold hereunder under the Securities Act.

            Section 3.14 Pledge of Securities. The Company acknowledges and
agrees that the Securities may be pledged by the Purchaser in connection with a
bona fide margin agreement or other loan or financing arrangement that is
secured by the Common Stock. The pledge of Common Stock shall not be deemed to
be a transfer, sale or assignment of the Common Stock hereunder, and the
Purchaser shall not be required to provide the Company with any notice of such
pledge or otherwise make any delivery to the Company pursuant to this Agreement
or any other Transaction Document; provided that the Purchaser and its pledgee
shall be required to comply with the provisions of Article V hereof in order to
effect a sale, transfer or assignment of Common Stock to such pledgee. At the
Purchaser's expense, the Company hereby agrees to execute and deliver such
documentation as a pledgee of the Common Stock may reasonably request in
connection with a pledge of the Common Stock to such pledgee by the Purchaser.

            Section 3.15 Confidentiality. Each party agrees that it will not
disclose and it will cause its officers, directors, employees, representatives,
agents, and advisers not to disclose, any Confidential Information (as
hereinafter defined) with respect to the other party furnished, at any time or
in any manner, provided that (i) any disclosure of such information may be made
to which the Company and Purchaser consent in writing; and (ii) such information
may be disclosed if so required by law or regulatory authority. "Confidential
Information" means information or knowledge obtained in any due diligence or
other investigation relating to the negotiation and execution of this Agreement,
information relating to the terms of the transactions contemplated hereby and
any information identified as confidential in writing from one party to the
other; provided, however, that Confidential Information shall not include
information or knowledge that (a) becomes generally available to the public
absent any breach of this Section 3.15, (b) was available on a non-confidential
basis to a party prior to its disclosure pursuant to this Agreement, or (c)
becomes available on a non-confidential basis from a third party who is not
bound to keep such information confidential.

            Section 3.16 Best Efforts. Each of the parties hereto shall use its
best efforts to satisfy each of the conditions to be satisfied by it as provided
in Sections 4.1 and 4.2 of this Agreement.

                               CERTIFICATE LEGEND

            Section 5.1 Legend. Each certificate representing the Securities
shall be stamped or otherwise imprinted with a legend substantially in the
following form (in addition to any legend required by applicable state
securities or "blue sky" laws):

         THE SECURITIES REPRESENTED BY THIS CERTIFICATE (THE "SECURITIES") HAVE
         NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE
         "SECURITIES ACT") OR ANY STATE SECURITIES LAWS AND MAY NOT BE SOLD,
         TRANSFERRED OR OTHERWISE DISPOSED OF UNLESS REGISTERED UNDER THE
         SECURITIES ACT AND UNDER APPLICABLE STATE SECURITIES LAWS OR NUTRITION
         21, INC. SHALL HAVE RECEIVED AN OPINION OF COUNSEL REASONABLY
         SATISFACTORY TO NUTRITION 21, INC. THAT REGISTRATION OF SUCH SECURITIES
         UNDER THE SECURITIES ACT AND UNDER THE PROVISIONS OF APPLICABLE STATE
         SECURITIES LAWS IS NOT REQUIRED.

                                       21
<PAGE>

         The Company agrees, upon the Purchaser's reasonable request, to reissue
certificates representing any of the Shares or Warrant Shares, without the
legend set forth above (i) while a registration statement (including the
Registration Statement to be filed pursuant to the Registration Rights
Agreement) providing for the resale of such Securities is effective under the
Securities Act, (ii) following any sale of such Securities pursuant to Rule 144
(assuming the transferor is not an affiliate of the Company), (iii) if such
Securities are eligible for sale under Rule 144(k) (to the extent that the
Purchaser provides a certification or legal opinion to the Company to that
effect), or (iv) if such legend is not required under applicable requirements of
the Securities Act (including controlling judicial interpretations and
pronouncements issued by the Commission). Following the effective date of the
Registration Statement (as defined in the Registration Rights Agreement) or at
such earlier time as a legend is no longer required for the Registrable
Securities (as defined in the Registration Rights Agreement), the Company will,
promptly following the delivery by the Purchaser to the Company or the Company's
transfer agent of a legended certificate representing such Securities, deliver
or cause to be delivered to the Purchaser a certificate representing such
Securities that is free from all restrictive legends. The restrictions on
transfer contained in this Section 5.1 shall be in addition to, and not by way
of limitation of, any other restrictions on transfer contained in any other
section of this Agreement. Whenever a certificate representing the Shares or
Warrant Shares is required to be issued to the Purchaser without a legend, in
lieu of delivering physical certificates representing the Shares or Warrant
Shares, provided the Company's transfer agent is participating in the Depository
Trust Company ("DTC") Fast Automated Securities Transfer program, the Company
shall cause its transfer agent to electronically transmit the Shares or Warrant
Shares to the Purchaser by crediting the account of the Purchaser's Prime Broker
with DTC through its Deposit Withdrawal Agent Commission ("DWAC") system (to the
extent not inconsistent with any provisions of this Agreement).

                                   ARTICLE VI

                                 INDEMNIFICATION

            Section 6.1 General Indemnity. The Company agrees to indemnify and
hold harmless the Purchaser (and its respective directors, officers, agents,
managers, partners, members, shareholders, affiliates, successors and assigns)
from and against any and all losses, liabilities, deficiencies, costs, damages
and expenses (including, without limitation, reasonable attorneys' fees, charges
and disbursements) incurred by the Purchaser and its directors, officers,
agents, managers, partners, members, shareholders, affiliates, successors and
assigns as a result of any inaccuracy in or breach of any of the
representations, warranties or covenants made by the Company herein. The
Purchaser agrees to indemnify and hold harmless the Company and its directors,
officers, affiliates, agents, successors and assigns from and against any and
all losses, liabilities, deficiencies, costs, damages and expenses (including,
without limitation, reasonable attorneys' fees, charges and disbursements)
incurred by the Company and its directors, officers, affiliates, agents,
successors and assigns as a direct result of any inaccuracy in or breach of the
representations, warranties or covenants made by the Purchaser herein. The
maximum aggregate liability of the Purchaser pursuant to its indemnification
obligations under this Article VI shall not exceed the Purchase Price paid by
the Purchaser.

            Section 6.2 Indemnification Procedure. Any party entitled to
indemnification under this Article VI (an "indemnified party") will give written
notice to the indemnifying party of any matters giving rise to a claim for
indemnification; provided, that the failure of any indemnified party to give
notice as provided herein shall not relieve the indemnifying party of its
obligations under this Article VI except to the extent that the indemnifying
party is actually prejudiced by such failure to give notice. In case any such
action, proceeding or claim is brought against an indemnified party in respect
of which indemnification is sought hereunder, the indemnifying party shall be
entitled to participate in and, unless in the reasonable judgment of the
indemnifying party a conflict of interest between it and the indemnified party
exists with respect to such action, proceeding or claim (in which case the
indemnifying party shall be responsible for the reasonable fees and expenses of
one separate counsel for the indemnified parties), to assume the defense thereof
with counsel reasonably satisfactory to the indemnified party. In the event that

                                       22
<PAGE>

the indemnifying party advises an indemnified party that it will not contest
such a claim for indemnification hereunder, or fails, within thirty (30) days of
receipt of any indemnification notice to notify, in writing, such person of its
election to defend, settle or compromise, at its sole cost and expense, any
action, proceeding or claim (or discontinues its defense at any time after it
commences such defense), then the indemnified party may, at its option, defend,
settle or otherwise compromise or pay such action or claim. In any event, unless
and until the indemnifying party elects in writing to assume and does so assume
the defense of any such claim, proceeding or action, the indemnified party's
reasonable costs and expenses arising out of the defense, settlement or
compromise of any such action, claim or proceeding shall be losses subject to
indemnification hereunder. The indemnified party shall cooperate fully with the
indemnifying party in connection with any negotiation or defense of any such
action or claim by the indemnifying party and shall furnish to the indemnifying
party all information reasonably available to the indemnified party which
relates to such action or claim. The indemnifying party shall keep the
indemnified party fully apprised at all times as to the status of the defense or
any settlement negotiations with respect thereto. If the indemnifying party
elects to defend any such action or claim, then the indemnified party shall be
entitled to participate in such defense with counsel of its choice at its sole
cost and expense. The indemnifying party shall not be liable for any settlement
of any action, claim or proceeding effected without its prior written consent
which consent shall not be unreasonably withheld. Notwithstanding anything in
this Article VI to the contrary, the indemnifying party shall not, without the
indemnified party's prior written consent, settle or compromise any claim or
consent to entry of any judgment in respect thereof which imposes any future
obligation on the indemnified party or which does not include, as an
unconditional term thereof, the giving by the claimant or the plaintiff to the
indemnified party of a release from all liability in respect of such claim. The
indemnification required by this Article VI shall be made by periodic payments
of the amount thereof during the course of investigation or defense, as and when
bills are received or expense, loss, damage or liability is incurred, so long as
the indemnified party irrevocably agrees to refund such moneys if it is
ultimately determined by a court of competent jurisdiction that such party was
not entitled to indemnification. The indemnity agreements contained herein shall
be in addition to (a) any cause of action or similar rights of the indemnified
party against the indemnifying party or others, and (b) any liabilities the
indemnifying party may be subject to pursuant to the law.

                                  ARTICLE VII

                                  MISCELLANEOUS

            Section 7.1 Fees and Expenses. Each party shall pay the fees and
expenses of its advisors, counsel, accountants and other experts, if any, and
all other expenses, incurred by such party incident to the negotiation,
preparation, execution, delivery and performance of this Agreement. The Company
and the Purchaser hereby agree that the prevailing party in any suit, action or
proceeding arising out of or relating to this Agreement or the other Transaction
Documents, shall be entitled to reimbursement for reasonable legal fees from the
non-prevailing party.

                                       23

            Section 7.2 Specific Performance; Consent to Jurisdiction; Venue.

            (a) The Company and the Purchaser acknowledge and agree that
irreparable damage would occur in the event that any of the provisions of this
Agreement or the other Transaction Documents are not performed in accordance
with their specific terms or are otherwise breached. It is accordingly agreed
that the parties shall be entitled to an injunction or injunctions to prevent or
cure breaches of the provisions of this Agreement or the other Transaction
Documents and to enforce specifically the terms and provisions hereof or
thereof, this being in addition to any other remedy to which any of them may be
entitled by law or equity.

            (b) The parties agree that venue for any dispute arising under this
Agreement will lie exclusively in the state or federal courts located in New
York County, New York, and the parties irrevocably waive any right to raise
forum non conveniens or any other argument that New York is not the proper
venue. The parties irrevocably consent to personal jurisdiction in the state and
federal courts of the state of New York. The Company and the Purchaser consent
to process being served in any such suit, action or proceeding by mailing a copy
thereof 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 in this Section 7.2 shall affect
or limit any right to serve process in any other manner permitted by law. The
parties hereby waive all rights to a trial by jury.

            Section 7.3 Entire Agreement; Amendment. This Agreement and the
Transaction Documents contain the entire understanding and agreement of the
parties with respect to the matters covered hereby and, except as specifically
set forth herein or in the other Transaction Documents, neither the Company nor
the Purchaser makes any representation, warranty, covenant or undertaking with
respect to such matters, and they supersede all prior understandings and
agreements with respect to said subject matter, all of which are merged herein.
Following the Closing, no provision of this Agreement may be waived or amended
other than by a written instrument signed by the Company and the Purchaser. Any
amendment or waiver effected in accordance with this Section 7.3 shall be
binding upon the Purchaser (and their permitted assigns) and the Company.

            Section 7.4 Notices. Any notice, demand, request, waiver or other
communication required or permitted to be given hereunder shall be in writing
and shall be effective (a) upon hand delivery by telecopy or facsimile
(evidenced by a successful transmission) at the address or number designated
below (if delivered on a business day during normal business hours where such
notice is to be received), or the first business day following such delivery (if
delivered other than on a business day during normal business hours where such
notice is to be received) or (b) on the second business day following the date
of mailing by express courier service, fully prepaid, addressed to such address,
or upon actual receipt of such mailing, whichever shall first occur. The

accordance with the provisions of this Section 7.4.

            Section 7.5 Waivers. No waiver by any party 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 other
provision, condition or requirement hereof, nor shall any delay or omission of

any such right accruing to it thereafter.

            Section 7.6 Headings. The article, section and subsection headings
in this Agreement are for convenience only and shall not constitute a part of
this Agreement for any other purpose and shall not be deemed to limit or affect
any of the provisions hereof.

            Section 7.7 Successors and Assigns. This Agreement shall be binding
upon and inure to the benefit of the parties and their successors and assigns.
After the Closing, the assignment by a party to this Agreement of any rights
hereunder shall not affect the obligations of such party under this Agreement.
Subject to Section 5.1 hereof, the Purchaser may assign the Securities and its
rights under this Agreement and the other Transaction Documents and any other
rights hereto and thereto without the consent of the Company so long as the
transferee is an "accredited investor" as defined in Regulation D under the
Securities Act and agrees to be bound by all of the provisions of this Agreement
and the other Transaction Documents.

            Section 7.8 No Third Party Beneficiaries. Except as expressly set
forth in Article VI hereof, this Agreement is intended for the benefit of the
parties hereto and their respective permitted successors and assigns and is not
for the benefit of, nor may any provision hereof be enforced by, any other
person.

            Section 7.9 Governing Law. This Agreement shall be governed by and
construed in accordance with the internal laws of the State of New York, without
giving effect to any of the conflicts of law principles which would result in
the application of the substantive law of another jurisdiction. This Agreement
shall not be interpreted or construed with any presumption against the party
causing this Agreement to be drafted.

            Section 7.10 Survival. The representations, warranties and covenants
of the Company and the Purchaser shall survive the execution and delivery hereof
and the Closing.

            Section 7.11 Counterparts. This Agreement may be executed in any
number of counterparts, all of which taken together shall constitute one and the
same instrument and shall become effective when counterparts have been signed by
each party and delivered to the other parties hereto, it being understood that
all parties need not sign the same counterpart. In the event that any signature
is delivered by facsimile transmission, such signature shall create a valid
binding obligation of the party executing (or on whose behalf such signature is
executed) the same with the same force and effect as if such facsimile signature
were the original thereof.

            Section 7.12 Publicity. The Company agrees that it will not
disclose, and will not include in any public announcement, the names of the
Purchaser without the consent of the Purchaser, which consent shall not be
unreasonably withheld or delayed, or unless and until such disclosure is
required by law, rule or applicable regulation, and then only to the extent of
such requirement.

            Section 7.13 Severability. The provisions of this Agreement are
severable and, in the event that any court of competent jurisdiction shall
determine that any one or more of the provisions or part of the provisions
contained in this Agreement shall, for any reason, be held to be invalid,
illegal or unenforceable in any respect, such invalidity, illegality or
unenforceability shall not affect any other provision or part of a provision of
this Agreement and this Agreement shall be reformed and construed as if such
invalid or illegal or unenforceable provision, or part of such provision, had
never been contained herein, so that such provisions would be valid, legal and
enforceable to the maximum extent possible.

                                       26
<PAGE>

            Section 7.14 Further Assurances. From and after the date of this
Agreement, upon the request of the Purchaser or the Company, the Company and the
Purchaser shall execute and deliver such instruments, documents and other
writings as may be reasonably necessary or desirable to confirm and carry out
and to effectuate fully the intent and purposes of this Agreement, the Warrant
and the Registration Rights Agreement.

            Section 7.15 Delivery of Securities. Notwithstanding anything
contained in this Agreement or any other Transaction Document to the contrary,
unless otherwise directed in writing by the Purchaser, all of the Purchaser's
securities purchased pursuant to this Agreement (and all securities which are
issuable to the Purchaser pursuant to the terms of this Agreement or any other
agreement or instrument entered into, or delivered, in connection with execution
of this Agreement or the consummation of the transaction contemplated hereby)
shall be registered in the name of the Purchaser, and the Company shall, and
shall cause its agents and representatives to, deliver all certificates
representing such securities to Goldman, Sachs & Co., One New York Plaza, New
York, New York 10004, Attention: Justin Freedland, and copies of all
certificates representing such securities shall be sent to the Purchaser in
accordance with Section 7.4 of this Agreement.

            Section 7.16 Independent Nature of the Purchaser. The Company
acknowledges that the obligations of the Purchaser under the Transaction
Documents are several and not joint with the obligations of any third party
purchaser of the Company's securities, and the Purchaser shall not be
responsible in any way for the performance of the obligations of any third party
purchaser of the Company's securities. The Company acknowledges that the
decision of the Purchaser to purchase Securities pursuant to the Transaction
Documents has been made by the Purchaser independently of any third party
purchaser of the Company's securities. Nothing contained herein or in any other
Transaction Document or any agreement of any such third party purchaser, and no
action taken by the Purchaser pursuant to any of the Transaction Documents or
any such third party purchaser pursuant thereto, shall be deemed to constitute
the Purchaser and any third party purchaser of the Company's securities as a
partnership, an association, a joint venture or any other kind of entity or
group, or create a presumption that the Purchaser and any such third party
purchaser of the Company's securities are in any way acting in concert or as a
group with respect to any matters. The Purchaser acknowledges that no third
party purchaser of the Company's securities has acted as agent for the Purchaser
in connection with making its investment hereunder and that no third party
purchaser of the Company's securities will be acting as agent of the Purchaser
in connection with monitoring its investment in the Securities or enforcing its
rights under the Transaction Documents. The Company acknowledges that the
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 third

                                       27
<PAGE>

party purchaser of the Company's securities to be joined as an additional party
in any proceeding for such purpose. To the extent that any such third party
purchasers purchase the same or similar securities as the Purchaser hereunder or
on the same or similar terms and conditions or pursuant to the same or similar
documents, all such matters are solely in the control of the Company, not the
action or decision of the Purchaser, and would be solely for the convenience of
the Company and not because it was required or requested to do so by the
Purchaser or any such third party purchaser. For clarification purposes only and
without implication that the contrary would otherwise be true, the transactions
contemplated by the Transaction Documents include only the transaction between
the Company and the Purchaser and do not include any other transaction between
the Company and any other third party purchaser of the Company's securities. The
Purchaser acknowledges that it has retained its own individual counsel with
respect to the transactions contemplated by the Transaction Documents.

                                 FORM OF OPINION

      1 The Company is a corporation duly incorporated, validly existing and in
good standing under the laws of the State of New York and has the requisite
corporate power to own, lease and operate its properties and assets, and to
carry on its business as presently conducted. The Company is duly qualified as a
foreign corporation to do business and is in good standing in every jurisdiction
in which the failure to so qualify would have a Material Adverse Effect.

      2 The Company has the requisite corporate power and authority to enter
into and perform its obligations under the Transaction Documents and to issue
the Shares and the Warrant. The execution, delivery and performance of each of
the Transaction Documents by the Company and the consummation by it of the
transactions contemplated thereby have been duly and validly authorized by all
necessary corporate action and no further consent or authorization of the
Company, its Board of Directors or its stockholders is required. Each of the
Transaction Documents have been duly executed and delivered and each of the
Transaction Documents constitutes a legal, valid and binding obligation of the
Company enforceable against the Company in accordance with its respective terms.
The Shares are not subject to any preemptive rights under the Certificate of
Incorporation or the Bylaws.

      3 The Shares and the Warrant have been duly authorized and, the Shares
when delivered against payment in full as provided in the Purchase Agreement,
will be validly issued, fully paid and nonassessable. The shares of Common Stock
issuable upon exercise of the Warrant have been duly authorized and reserved for
issuance, and when delivered against payment in full as provided in the Warrant,
will be validly issued, fully paid and nonassessable.

      4 The execution, delivery and performance of and compliance with the terms
of the Transaction Documents and the issuance of the Shares and the Warrant do
not (a) violate any provision of the Certificate of Incorporation or Bylaws, (b)
conflict with, or constitute a default (or an event which with notice or lapse
of time or both would become a default) under, or give to others any rights of
termination, amendment, acceleration or cancellation of, any material agreement,
mortgage, deed of trust, indenture, note, bond, license, lease agreement,
instrument or obligation to which the Company is a party and which is known to
us, (c) create or impose a lien, charge or encumbrance on any property of the
Company under any agreement or any commitment known to us to which the Company
is a party or by which the Company is bound or by which any of its respective
properties or assets are bound, or (d) result in a violation of any Federal,
state, local or foreign statute, rule, regulation, order, judgment, injunction
or decree (including Federal and state securities laws and regulations)
applicable to the Company or by which any property or asset of the Company is
bound or affected, except, in all cases other than violations pursuant to
clauses (a) and (d) above, for such conflicts, default, terminations,
amendments, acceleration, cancellations and violations as would not,
individually or in the aggregate, have a Material Adverse Effect.

<PAGE>

      5 No consent, approval or authorization of or designation, declaration or
filing with any governmental authority on the part of the Company is required
under Federal, state or local law, rule or regulation in connection with the
valid execution, delivery and performance of the Transaction Documents, or the
offer, sale or issuance of the Shares and the Warrant other than filings as may
be required by applicable Federal and state securities laws.

      6 To our knowledge, there is no action, suit, claim, investigation or
proceeding pending or threatened against the Company which questions the
validity of the Agreement or the transactions contemplated thereby or any action
taken or to be taken pursuant thereto. There is no action, suit, claim,
investigation or proceeding pending, or to our knowledge, threatened, against or
involving the Company or any of its properties or assets and which, if adversely
determined, is reasonably likely to result in a Material Adverse Effect. There
are no outstanding orders, judgments, injunctions, awards or decrees of any
court, arbitrator or governmental or regulatory body against the Company or any
officers or directors of the Company in their capacities as such.

      7 The offer, issuance and sale of the Shares and the Warrant are exempt
from the registration requirements of the Securities Act of 1933, as amended.

      8 The Company is not, and as a result of and immediately upon Closing will
not be, an "investment company" or a company "controlled" by an "investment
company," within the meaning of the Investment Company Act of 1940, as amended.EXHIBIT 4.5

            On or prior to the Filing Date the Company shall prepare and file
with the Commission a "resale" Registration Statement providing for the resale
of all Registrable Securities for an offering to be made on a continuous basis
pursuant to Rule 415. The Registration Statement shall be on Form S-3 (except if
the Company is not then eligible to register for resale the Registrable
Securities on Form S-3, in which case such registration shall be on another
appropriate form in accordance herewith and the Securities Act and the rules
promulgated thereunder). Such Registration Statement shall cover to the extent
allowable under the Securities Act and the rules promulgated thereunder
(including Rule 416), such indeterminate number of additional shares of Common
Stock resulting from stock splits, stock dividends or similar transactions with
respect to the Registrable Securities. The Company shall (i) not permit any
securities other than the Registrable Securities to be included in the

in the Registration Statement, at its option and solely for its convenience,
other similar securities issued by the Company (i.e. common stock previously
issued by the Company or common stock issued or issuable on exercise of warrants
previously issued by the Company) and (ii) use its best efforts to cause the
Registration Statement to be declared effective under the Securities Act as
promptly as possible after the filing thereof, but in any event prior to the
Effectiveness Date, and to keep such Registration Statement continuously
effective under the Securities Act until such date as is the earlier of (x) the

without any restriction pursuant to Rule 144(k) as determined by the counsel to
the Company pursuant to a written opinion letter, addressed to the Company's
transfer agent to such effect (the "Effectiveness Period"). The Company shall
request that the effective time of the Registration Statement be 4:00 p.m.
Eastern Time on the effective date. If at any time and for any reason, an
additional Registration Statement is required to be filed because at such time
the actual number of shares of Common Stock into which the Warrant is
exercisable exceeds the number of shares of Registrable Securities remaining
under the Registration Statement, the Company shall have twenty (20) Business
Days to file such additional Registration Statement, and the Company shall use
its best efforts to cause such additional Registration Statement to be declared
effective by the Commission as soon as possible, but in no event later than
sixty (60) days after filing.

      3.    Registration Procedures.

            In connection with the Company's registration obligations hereunder,
the Company shall:

            (a) Prepare and file with the Commission on or prior to the Filing
Date, a Registration Statement on Form S-3 (or if the Company is not then
eligible to register for resale the Registrable Securities on Form S-3 such
registration shall be on another appropriate form in accordance herewith and the
Securities Act and the rules promulgated thereunder) in accordance with the plan
of distribution as set forth on Exhibit A hereto and in accordance with
applicable law, and cause the Registration Statement to become effective and
remain effective as provided herein; provided, however, that not less than five
(5) Business Days prior to the filing of the Registration Statement or any
related Prospectus or any amendment or supplement thereto (including any
document that would be incorporated therein by reference), the Company shall (i)
furnish to the Holders, copies of all such documents proposed to be filed, which
documents (other than those incorporated by reference) will be subject to the
review of such Holders, and (ii) cause its officers and directors, counsel and
independent certified public accountants to respond to such inquiries as shall
be necessary, in the reasonable opinion of the Holders, to conduct a reasonable
review of the documents. The Company shall not file the Registration Statement
or any such Prospectus or any amendments or supplements thereto to which the
Holders of a majority of the Registrable Securities shall reasonably object in
writing within five (5) Business Days of their receipt thereof.

                                       4

            (b) (i) Prepare and file with the Commission such amendments,
including post-effective amendments, to the Registration Statement as may be

order to register for resale under the Securities Act all of the Registrable
Securities; (ii) cause the related Prospectus to be amended or supplemented by
any required Prospectus supplement, and as so supplemented or amended to be
filed pursuant to Rule 424 (or any similar provisions then in force) promulgated
under the Securities Act; (iii) respond as promptly as possible, but in no event
later than ten (10) Business Days, to any comments received from the Commission
with respect to the Registration Statement or any amendment thereto and to
provide the Holders, within such ten (10) Business Day period, true and complete
copies of all correspondence from and to the Commission relating to the
Registration Statement; (iv) file the final prospectus pursuant to Rule 424 of
the Securities Act no later than 9:00 a.m. Eastern Time on the Business Day
following the date the Registration Statement is declared effective by the
Commission; and (v) comply in all material respects with the provisions of the
Securities Act and the Exchange Act with respect to the disposition of all
Registrable Securities covered by the Registration Statement during the
Effectiveness Period in accordance with the intended methods of disposition by
the Holders thereof set forth in the Registration Statement as so amended or in
such Prospectus as so supplemented.

            (c) Notify the Holders of Registrable Securities as promptly as
possible (and, in the case of (i)(A) below, not less than three (3) Business
Days prior to such filing, and in the case of (iii) below, on the same day of
receipt by the Company of such notice from the Commission) and (if requested by
any such Person) confirm such notice in writing no later than one (1) Business
Day following the day (i)(A) when a Prospectus or any Prospectus supplement or
post-effective amendment to the Registration Statement is filed; (B) when the
Commission notifies the Company whether there will be a "review" of such
Registration Statement and whenever the Commission comments in writing on such
Registration Statement and (C) with respect to the Registration Statement or any
post-effective amendment, when the same has become effective; (ii) of any
request by the Commission or any other Federal or state governmental authority
for amendments or supplements to the Registration Statement or Prospectus or for
additional information; (iii) of the issuance by the Commission of any stop
order suspending the effectiveness of the Registration Statement covering any or
all of the Registrable Securities or the initiation or threatening of any
Proceedings for that purpose; (iv) if at any time any of the representations and
warranties of the Company contained in any agreement contemplated hereby ceases
to be true and correct in all material respects; (v) of the receipt by the
Company of any notification with respect to the suspension of the qualification
or exemption from qualification of any of the Registrable Securities for sale in
any jurisdiction, or the initiation or threatening of any Proceeding for such
purpose; and (vi) of the occurrence of any event that makes any statement made
in the Registration Statement or Prospectus or any document incorporated or
deemed to be incorporated therein by reference untrue in any material respect or
that requires any revisions to the Registration Statement, Prospectus or other
documents so that, in the case of the Registration Statement or the Prospectus,
as the case may be, it will not contain any untrue statement of a material fact
or omit to state any material fact required to be stated therein or necessary to
make the statements therein, in the light of the circumstances under which they
were made, not misleading.

                                       5
<PAGE>

            (d) Use its best efforts to avoid the issuance of, or, if issued,
obtain the withdrawal of, as promptly as possible, (i) any order suspending the
effectiveness of the Registration Statement or (ii) any suspension of the
qualification (or exemption from qualification) of any of the Registrable
Securities for sale in any jurisdiction.

            (e) If requested by the Holders of a majority in interest of the
Registrable Securities, (i) promptly incorporate in a Prospectus supplement or
post-effective amendment to the Registration Statement such information as the
Company reasonably agrees should be included therein and (ii) make all required
filings of such Prospectus supplement or such post-effective amendment as soon
as practicable after the Company has received notification of the matters to be
incorporated in such Prospectus supplement or post-effective amendment.

            (f) If requested by any Holder, furnish to such Holder, without
charge, at least one conformed copy of each Registration Statement and each
amendment thereto, including financial statements and schedules, all documents
incorporated or deemed to be incorporated therein by reference, and all exhibits
to the extent requested by such Person (including those previously furnished or
incorporated by reference) promptly after the filing of such documents with the
Commission.

            (g) If requested by any Holder, promptly deliver to each Holder,
without charge, as many copies of the Prospectus or Prospectuses (including each
form of prospectus) and each amendment or supplement thereto as such Persons may
reasonably request; and subject to the provisions of Sections 3(m) and 3(n), the
Company hereby consents to the use of such Prospectus and each amendment or
supplement thereto by each of the selling Holders in connection with the
offering and sale of the Registrable Securities covered by such Prospectus and
any amendment or supplement thereto.

            (h) If requested by any Holder, prior to any public offering of
Registrable Securities, use its best efforts to register or qualify or cooperate
with the selling Holders in connection with the registration or qualification
(or exemption from such registration or qualification) of such Registrable
Securities for offer and sale under the securities or Blue Sky laws of such
jurisdictions within the United States as any Holder requests in writing, to
keep each such registration or qualification (or exemption therefrom) effective
during the Effectiveness Period and to do any and all other acts or things
necessary or advisable to enable the disposition in such jurisdictions of the
Registrable Securities covered by a Registration Statement; provided, however,
that the Company shall not be required to qualify generally to do business in
any jurisdiction where it is not then so qualified or to take any action that
would subject it to general service of process in any such jurisdiction where it
is not then so subject or subject the Company to any material tax in any such
jurisdiction where it is not then so subject.

            (i) Cooperate with the Holders to facilitate the timely preparation
and delivery of certificates representing Registrable Securities to be sold
pursuant to a Registration Statement, which certificates, to the extent
permitted by the Purchase Agreement and applicable federal and state securities
laws, shall be free of all restrictive legends, and to enable such Registrable
Securities to be in such denominations and registered in such names as any
Holder may request in connection with any sale of Registrable Securities.

                                       6
<PAGE>

            (j) Upon the occurrence of any event contemplated by Section
3(c)(vi), as promptly as possible, prepare a supplement or amendment, including
a post-effective amendment, to the Registration Statement or a supplement to the
related Prospectus or any document incorporated or deemed to be incorporated
therein by reference, and file any other required document so that, as
thereafter delivered, neither the Registration Statement nor such Prospectus
will contain an untrue statement of a material fact or omit to state a material
fact required to be stated therein or necessary to make the statements therein,
in the light of the circumstances under which they were made, not misleading.

            (k) Use its best efforts to cause all Registrable Securities
relating to the Registration Statement to be listed on the Nasdaq Capital Market
or any other securities exchange, quotation system or market, if any, on which
similar securities issued by the Company are then listed or traded as and when
required pursuant to the Purchase Agreement.

            (l) Comply in all material respects with all applicable rules and
regulations of the Commission and make generally available to its security
holders all documents filed or required to be filed with the Commission.

            (m) The Company may require each selling Holder to furnish to the
Company information regarding such Holder and the distribution of such
Registrable Securities as is required by law to be disclosed in the Registration
Statement, Prospectus, or any amendment or supplement thereto, and the Company
may exclude from such registration the Registrable Securities of any such Holder
who unreasonably fails to furnish such information within a reasonable time
after receiving such request.

            If the Registration Statement refers to any Holder by name or
otherwise as the holder of any securities of the Company, then such Holder shall
have the right to require (if such reference to such Holder by name or otherwise
is not required by the Securities Act or any similar federal statute then in
force) the deletion of the reference to such Holder in any amendment or
supplement to the Registration Statement filed or prepared subsequent to the
time that such reference ceases to be required.

            Each Holder covenants and agrees that it will not sell any
Registrable Securities under the Registration Statement until the Company has
electronically filed the Prospectus as then amended or supplemented as
contemplated in Section 3(g) and notice from the Company that the Registration
Statement and any post-effective amendments thereto have become effective as
contemplated by Section 3(c).

            Each Holder agrees by its acquisition of such Registrable Securities
that, upon receipt of a notice from the Company of the occurrence of any event
of the kind described in Section 3(c)(ii), 3(c)(iii), 3(c)(iv), 3(c)(v),
3(c)(vi) or 3(n), such Holder will forthwith discontinue disposition of such
Registrable Securities under the Registration Statement until such Holder's
receipt of the copies of the supplemented Prospectus and/or amended Registration
Statement contemplated by Section 3(j), or until it is advised in writing (the
"Advice") by the Company that the use of the applicable Prospectus may be
resumed, and, in either case, has received copies of any additional or
supplemental filings that are incorporated or deemed to be incorporated by
reference in such Prospectus or Registration Statement.

is declared effective by the Commission, if (i) there is material non-public
information regarding the Company which the Company's Board of Directors (the
"Board") determines not to be in the Company's best interest to disclose and
which the Company is not otherwise required to disclose, (ii) there is a
significant business opportunity (including, but not limited to, the acquisition
or disposition of assets (other than in the ordinary course of business) or any
merger, consolidation, tender offer or other similar transaction) available to
the Company which the Board determines not to be in the Company's best interest
to disclose, or (iii) the Company is required to file a post-effective amendment
to the Registration Statement to incorporate the Company's quarterly and annual
reports and audited financial statements on Forms 10-Q and 10-K, then the
Company may (x) postpone or suspend filing of a registration statement for a
period not to exceed thirty (30) consecutive days or (y) postpone or suspend
effectiveness of a registration statement for a period not to exceed twenty (20)
consecutive days; provided that the Company may not postpone or suspend
effectiveness of a registration statement under this Section 3(n) for more than
forty-five (45) days in the aggregate during any three hundred sixty (360) day

permitted for consecutive twenty (20) day periods arising out of the same set of
facts, circumstances or transactions.

notwithstanding any termination of this Agreement, indemnify and hold harmless
each Holder, the officers, directors, managers, partners, members, shareholders,
agents, brokers, investment advisors and employees of each of them, each Person
who controls any such Holder (within the meaning of Section 15 of the Securities
Act or Section 20 of the Exchange Act) and the officers, directors, agents and
employees of each such controlling Person, to the fullest extent permitted by
applicable law, from and against any and all losses, claims, damages,
liabilities, costs (including, without limitation, costs of preparation and
attorneys' fees) and expenses (collectively, "Losses"), as incurred, arising out
of or relating to any violation of securities laws or untrue or alleged untrue
statement of a material fact contained in the Registration Statement, any
Prospectus or any form of prospectus or in any amendment or supplement thereto
or in any preliminary prospectus, or arising out of or relating to any omission
or alleged omission of a material fact required to be stated therein or
necessary to make the statements therein (in the case of any Prospectus or form
of prospectus or supplement thereto, in the light of the circumstances under
which they were made) not misleading, except to the extent, but only to the
extent, that such untrue statements or omissions are based solely upon
information regarding such Holder or such other Indemnified Party furnished in
writing to the Company by such Holder expressly for use therein. The Company
shall notify the Holders promptly of the institution, threat or assertion of any
Proceeding of which the Company is aware in connection with the transactions
contemplated by this Agreement.

            (b) Indemnification by Holders. Each Holder shall, severally and not
jointly, indemnify and hold harmless the Company, its directors, officers,
agents and employees, each Person who controls the Company (within the meaning
of Section 15 of the Securities Act and Section 20 of the Exchange Act), and the
directors, officers, agents and employees of such controlling Persons, to the

incurred, arising solely out of or based solely upon any untrue statement of a
material fact contained in the Registration Statement, any Prospectus, or any
form of prospectus, or arising solely out of or based solely upon any omission
of a material fact required to be stated therein or necessary to make the
statements therein (in the case of any Prospectus or form of prospectus or
supplement thereto, in the light of the circumstances under which they were
made) not misleading, to the extent, but only to the extent, that such untrue
statement or omission is contained in any information so furnished in writing by
such Holder or other Indemnifying Party to the Company specifically for
inclusion in the Registration Statement or such Prospectus. Notwithstanding
anything to the contrary contained herein, each Holder shall be liable under
this Section 5(b) for only that amount as does not exceed the net proceeds to
such Holder as a result of the sale of Registrable Securities pursuant to such
Registration Statement.

            (c) Conduct of Indemnification Proceedings. If any Proceeding shall
be brought or asserted against any Person entitled to indemnity hereunder (an
"Indemnified Party"), such Indemnified Party promptly shall notify the Person
from whom indemnity is sought (the "Indemnifying Party) in writing, and the
Indemnifying Party shall be entitled to assume the defense thereof, including
the employment of counsel reasonably satisfactory to the Indemnified Party and
the payment of all fees and expenses incurred in connection with defense
thereof; provided, that the failure of any Indemnified Party to give such notice
shall not relieve the Indemnifying Party of its obligations or liabilities
pursuant to this Agreement, except (and only) to the extent that it shall be
finally determined by a court of competent jurisdiction (which determination is
not subject to appeal or further review) that such failure shall have
proximately and materially adversely prejudiced the Indemnifying Party.

            An Indemnified Party shall have the right to employ separate counsel
in any such Proceeding and to participate in the defense thereof, but the fees
and expenses of such counsel shall be at the expense of such Indemnified Party
or Parties unless: (1) the Indemnifying Party has agreed in writing to pay such
fees and expenses; or (2) the Indemnifying Party shall have failed promptly to
assume the defense of such Proceeding and to employ counsel reasonably
satisfactory to such Indemnified Party in any such Proceeding; or (3) the named
parties to any such Proceeding (including any impleaded parties) include both
such Indemnified Party and the Indemnifying Party, and such parties shall have
been advised by counsel that a conflict of interest is likely to exist if the
same counsel were to represent such Indemnified Party and the Indemnifying Party
(in which case, if such Indemnified Party notifies the Indemnifying Party in
writing that it elects to employ one separate counsel at the expense of the
Indemnifying Party, the Indemnifying Party shall not have the right to assume
the defense thereof and the reasonable fees and expenses of such counsel shall
be at the expense of the Indemnifying Party). The Indemnifying Party shall not
be liable for any settlement of any such Proceeding effected without its written
consent, which consent shall not be unreasonably withheld or delayed. No
Indemnifying Party shall, without the prior written consent of the Indemnified
Party, effect any settlement of any pending or threatened Proceeding in respect
of which any Indemnified Party is a party and indemnity has been sought
hereunder, unless such settlement includes an unconditional release of such
Indemnified Party from all liability on claims that are the subject matter of
such Proceeding.

            All reasonable fees and expenses of the Indemnified Party (including
reasonable fees and expenses to the extent incurred in connection with
investigating or preparing to defend such Proceeding in a manner not
inconsistent with this Section) shall be paid to the Indemnified Party, as
incurred, within ten (10) Business Days of written notice thereof to the
Indemnifying Party (regardless of whether it is ultimately determined that an
Indemnified Party is not entitled to indemnification hereunder; provided, that
the Indemnified Party shall reimburse all such fees and expenses to the extent
it is finally judicially determined that such Indemnified Party is not entitled
to indemnification hereunder).

            (d) Contribution. If a claim for indemnification under Section 5(a)
or 5(b) is due but unavailable to an Indemnified Party because of a failure or
refusal of a governmental authority to enforce such indemnification in
accordance with its terms (by reason of public policy or otherwise), then each
Indemnifying Party, in lieu of indemnifying such Indemnified Party, shall
contribute to the amount paid or payable by such Indemnified Party as a result
of such Losses, in such proportion as is appropriate to reflect the relative
benefits received by the Indemnifying Party on the one hand and the Indemnified
Party on the other from the offering of the Common Stock and Warrant to the
Purchaser. If, but only if, the allocation provided by the foregoing sentence is
not permitted by applicable law, the allocation of contribution shall be made in
such proportion as is appropriate to reflect not only the relative benefits
referred to in the foregoing sentence but also the relative fault, as
applicable, of the Indemnifying Party and Indemnified Party in connection with
the actions, statements or omissions that resulted in such Losses as well as any
other relevant equitable considerations. The relative fault of such Indemnifying

                                       10
<PAGE>

Party and Indemnified Party shall be determined by reference to, among other
things, whether any action in question, including any untrue or alleged untrue
statement of a material fact or omission or alleged omission of a material fact,
has been taken or made by, or relates to information supplied by, such
Indemnifying Party or Indemnified Party, and the parties' relative intent,
knowledge, access to information and opportunity to correct or prevent such
action, statement or omission. The amount paid or payable by a party as a result
of any Losses shall be deemed to include, subject to the limitations set forth
in Section 5(c), any reasonable attorneys' or other reasonable fees or expenses
incurred by such party in connection with any Proceeding to the extent such
party would have been indemnified for such fees or expenses if the
indemnification provided for in this Section was available to such party in
accordance with its terms. In no event shall any selling Holder be required to
contribute an amount under this Section 5(d) in excess of the net proceeds
received by such Holder upon sale of such Holder's Registrable Securities
pursuant to the Registration Statement giving rise to such contribution
obligation.

            The parties hereto agree that it would not be just and equitable if
contribution pursuant to this Section 5(d) were determined by pro rata
allocation or by any other method of allocation that does not take into account
the equitable considerations referred to in the immediately preceding paragraph.
No Person guilty of fraudulent misrepresentation (within the meaning of Section
11(f) of the Securities Act) shall be entitled to contribution from any Person
who was not guilty of such fraudulent misrepresentation. The indemnity and
contribution agreements contained in this Section are in addition to any
liability that the Indemnifying Parties may have to the Indemnified Parties
pursuant to the law.

      6.    Rule 144.

            As long as any Holder owns any of the Warrant or Registrable
Securities, the Company covenants to timely file (or obtain extensions in
respect thereof and file within the applicable grace period) all reports
required to be filed by the Company after the date hereof pursuant to Section
13(a) or 15(d) of the Exchange Act and, upon the request of any Holder, to
promptly furnish such Holder with true and complete copies of all such filings.
As long as any Holder owns any of the Warrant or Registrable Securities, if the
Company is not required to file reports pursuant to Section 13(a) or 15(d) of
the Exchange Act, it will prepare and furnish to the Holders and make publicly
available in accordance with Rule 144(c) promulgated under the Securities Act
annual and quarterly financial statements, together with a discussion and
analysis of such financial statements in form and substance substantially
similar to those that would otherwise be required to be included in reports
required by Section 13(a) or 15(d) of the Exchange Act, as well as any other
information required thereby, in the time period that such filings would have
been required to have been made under the Exchange Act. The Company further
covenants that it will take such further action as any Holder may reasonably
request in writing, all to the extent required from time to time to enable such
Person to sell the Shares and the Warrant Shares without registration under the
Securities Act within the limitation of the exemptions provided by Rule 144
promulgated under the Securities Act, including providing any legal opinions
relating to such sale pursuant to Rule 144. Upon the request of any Holder, the
Company shall deliver to such Holder a written certification of a duly
authorized officer as to whether it has complied with such requirements.

                                       11

      7.    Miscellaneous.

            (a) Remedies. In the event of a breach by the Company or by a
Holder, of any of their obligations under this Agreement, such Holder or the
Company, as the case may be, in addition to being entitled to exercise all
rights granted by law and under this Agreement, including recovery of damages,
will be entitled to specific performance of its rights under this Agreement. The
Company and each Holder agree that monetary damages would not provide adequate
compensation for any losses incurred by reason of a breach by it of any of the
provisions of this Agreement and hereby further agrees that, in the event of any
action for specific performance in respect of such breach, it shall waive the
defense that a remedy at law would be adequate.

            (b) No Inconsistent Agreements. Neither the Company nor any of its
subsidiaries has, as of the date hereof entered into and currently in effect,
nor shall the Company or any of its subsidiaries, on or after the date of this
Agreement, enter into any agreement with respect to its securities that is
inconsistent with the rights granted to the Holders in this Agreement or
otherwise conflicts with the provisions hereof. Except as disclosed in Schedule
2.1(c) of the Purchase Agreement or the Commission Documents, neither the
Company nor any of its subsidiaries has previously entered into any agreement
currently in effect granting any registration rights with respect to any of its
securities to any Person. Without limiting the generality of the foregoing,
without the written consent of the Holders of a majority of the then outstanding
Registrable Securities, the Company shall not grant to any Person the right to
request the Company to register any securities of the Company, under the
Securities Act unless the rights so granted are subject in all respects to the
prior rights in full of the Holders set forth herein, and are not otherwise in
conflict with the provisions of this Agreement.

            (c) No Piggyback on Registrations. Neither the Company nor any of
its security holders (other than the Holders in such capacity pursuant hereto or
as disclosed on Schedule 2.1(c) of the Purchase Agreement or holders of
securities contemplated by Section 2 above) may include securities of the
Company in the Registration Statement. The Company shall not after the date
hereof enter into any agreement providing such right to any of its
securityholders, unless the right so granted is subject in all respects to the
prior rights in full of the Holders set forth herein, and is not otherwise in
conflict with the provisions of this Agreement.

            (d) Piggy-Back Registrations. If at any time when there is not an
effective Registration Statement covering (i) Shares or (ii) Warrant Shares the
Company shall determine to prepare and file with the Commission a registration
statement relating to an offering for its own account or the account of others
under the Securities Act of any of its equity securities, other than on Form S-4
or Form S-8 (each as promulgated under the Securities Act) or their then
equivalents relating to equity securities to be issued solely in connection with
any acquisition of any entity or business or equity securities issuable in
connection with stock option or other employee benefit plans, the Company shall
send to each Holder written notice of such determination and, if within thirty
(30) days after receipt of such notice, or within such shorter period of time as
may be specified by the Company in such written notice as may be necessary for
the Company to comply with its obligations with respect to the timing of the
filing of such registration statement, any such Holder shall so request in
writing (which request shall specify the Registrable Securities intended to be
disposed of by such Holder), the Company will cause the registration under the

                                       12
<PAGE>

Securities Act of all Registrable Securities which the Company has been so
requested to register by such Holder, to the extent requisite to permit the
disposition of the Registrable Securities so to be registered, provided that if
at any time after giving written notice of its intention to register any
securities and prior to the effective date of the registration statement filed
in connection with such registration, the Company shall determine for any reason
not to register or to delay registration of such securities, the Company may, at
its election, give written notice of such determination to such Holder and,
thereupon, (i) in the case of a determination not to register, shall be relieved
of its obligation under this Section 7(d) to register any Registrable Securities
in connection with such registration (but not from its obligation to pay
expenses in accordance with Section 4 hereof), and (ii) in the case of a
determination to delay registering, shall be permitted to delay registering any
Registrable Securities being registered pursuant to this Section 7(d) for the
same period as the delay in registering such other securities. The Company shall
include in such registration statement all or any part of such Registrable
Securities such Holder requests to be registered; provided, however, that the
Company shall not be required to register any Registrable Securities pursuant to
this Section 7(d) that are eligible for sale pursuant to Rule 144(k) of the
Securities Act. In the case of an underwritten public offering, if the managing
underwriter(s) or underwriter(s) should reasonably object to the inclusion of
the Registrable Securities in such registration statement, then if the Company
after consultation with the managing underwriter should reasonably determine
that the inclusion of such Registrable Securities would materially adversely
affect the offering contemplated in such registration statement, and based on
such determination recommends inclusion in such registration statement of fewer
or none of the Registrable Securities of the Holders, then (x) the number of
Registrable Securities of the Holders included in such registration statement
shall be reduced pro-rata among such Holders (based upon the number of
Registrable Securities requested to be included in the registration), if the
Company after consultation with the underwriter(s) recommends the inclusion of
fewer Registrable Securities, or (y) none of the Registrable Securities of the
Holders shall be included in such registration statement, if the Company after
consultation with the underwriter(s) recommends the inclusion of none of such
Registrable Securities; provided, however, that if securities are being offered
for the account of other persons or entities as well as the Company, such
reduction shall not represent a greater fraction of the number of Registrable
securities intended to be offered by the Holders than the fraction of similar
reductions imposed on such other persons or entities (other than the Company).

            (e) Failure to File Registration Statement and Other Events. The
Company and the Purchaser agree that the Holders will suffer damages if the
Registration Statement is not filed on or prior to the Filing Date and not
declared effective by the Commission on or prior to the Effectiveness Date and
maintained in the manner contemplated herein during the Effectiveness Period or
if certain other events occur. The Company and the Holders further agree that it
would not be feasible to ascertain the extent of such damages with precision.
Accordingly, if (A) the Registration Statement is not filed on or prior to the
Filing Date, or (B) the Registration Statement is not declared effective by the
Commission on or prior to the Effectiveness Date (or in the event an additional

                                       13
<PAGE>

Registration Statement is filed because the actual number of shares of Common
Stock into which the Warrant is exercisable exceeds the number of shares of
Common Stock initially registered is not filed and declared effective with the
time periods set forth in Section 2), or (C) the Company fails to file with the
Commission a request for acceleration in accordance with Rule 461 promulgated
under the Securities Act within three (3) Business Days of the date that the
Company is notified (orally or in writing, whichever is earlier) by the
Commission that a Registration Statement will not be "reviewed," or not subject
to further review, or (D) the Registration Statement is filed with and declared
effective by the Commission but thereafter ceases to be effective as to all
Registrable Securities at any time prior to the expiration of the Effectiveness
Period, without being succeeded promptly by a subsequent Registration Statement
filed with and declared effective by the Commission in accordance with Section 2
hereof, or (E) the Company has breached Section 3(n), or (F) trading in the
Common Stock shall be suspended or if the Common Stock is delisted from the
Nasdaq Capital Market (or other principal exchange on which the Common Stock is
listed or traded) for any reason for more than three (3) Business Days in the
aggregate without subsequent listing on another exchange or the quotation of the
Common Stock on the OTC Bulletin Board (any such failure or breach being
referred to as an "Event," and for purposes of clauses (A) and (B) the date on
which such Event occurs, or for purposes of clause (C) the date on which such
three (3) Business Day period is exceeded, or for purposes of clause (D) after
more than fifteen (15) Business Days, or for purposes of clause (F) the date on
which such three (3) Business Day period is exceeded, being referred to as
"Event Date"), the Company shall pay an amount in cash as liquidated damages to
each Holder equal to one percent (1%) of the Holder's initial investment in the
Shares from the Event Date, less any number of Shares that have been sold by
such Holder, for each calendar month (prorated for shorter periods) until the
applicable Event is cured; provided, however, that in no event shall the amount
of liquidated damages payable at any time and from time to time to any Holder
pursuant to this Section 7(e) exceed an aggregate of eighteen percent (18%) of
the amount of the Holder's initial investment in the Shares. Notwithstanding
anything to the contrary in this paragraph (e), if (i) any of the Events
described in clauses (A), (B), (C), (D) or (F) shall have occurred, (II) on or
prior to the applicable Event Date, the Company shall have exercised its rights
under Section 3(n) hereof and (III) the postponement or suspension permitted
pursuant to such Section 3(n) shall remain effective as of such applicable Event
Date, then the applicable Event Date shall be deemed instead to occur on the
second Business Day following the termination of such postponement or
suspension. Liquidated damages payable by the Company pursuant to this Section
7(e) shall be payable on the first (1st) Business Day of each thirty (30) day
period following the Event Date. Notwithstanding anything to the contrary
contained herein, in no event shall any liquidated damages be payable with
respect to the Warrant or the Warrant Shares.

            (f) Amendments and Waivers. The provisions of this Agreement,
including the provisions of this sentence, may not be amended, modified or
supplemented, and waivers or consents to departures from the provisions hereof
may not be given, unless the same shall be in writing and signed by the Company
and the Holders of a majority of the Registrable Securities outstanding.

            (h) Successors and Assigns. This Agreement shall be binding upon and
inure to the benefit of the parties and their successors and permitted assigns
and shall inure to the benefit of each Holder and its successors and assigns.
The Company may not assign this Agreement or any of its rights or obligations
hereunder without the prior written consent of each Holder. The Purchaser may
assign its rights hereunder in the manner and to the Persons as permitted under
the Purchase Agreement.

            (i) Assignment of Registration Rights. The rights of each Holder
hereunder, including the right to have the Company register for resale
Registrable Securities in accordance with the terms of this Agreement, shall be
automatically assignable by each Holder to any Person of all or a portion of the
Shares or Registrable Securities if: (i) such Holder agrees in writing with the
transferee or assignee to assign such rights, and a copy of such agreement is
furnished to the Company within a reasonable time after such assignment, (ii)
the Company is, within a reasonable time after such transfer or assignment,
furnished with written notice of (a) the name and address of such transferee or
assignee, and (b) the securities with respect to which such registration rights
are being transferred or assigned, (iii) following such transfer or assignment
the further disposition of such securities by the transferee or assignees is
restricted under the Securities Act and applicable state securities laws, (iv)
at or before the time the Company receives the written notice contemplated by
clause (ii) of this Section, the transferee or assignee agrees in writing with
the Company to be bound by all of the provisions of this Agreement, and (v) such
transfer shall have been made in accordance with the applicable requirements of
the Purchase Agreement. The rights to assignment shall apply to the Holders (and
to subsequent) successors and assigns.

                                       15
<PAGE>

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

            (k) Governing Law; Jurisdiction. This Agreement shall be governed by
and construed in accordance with the internal laws of the State of New York,
without giving effect to any of the conflicts of law principles which would
result in the application of the substantive law of another jurisdiction. This
Agreement shall not be interpreted or construed with any presumption against the
party causing this Agreement to be drafted. The Company and the Holders agree
that venue for any dispute arising under this Agreement will lie exclusively in
the state or federal courts located in New York County, New York, and the
parties irrevocably waive any right to raise forum non conveniens or any other
argument that New York is not the proper venue. The Company and the Holders
irrevocably consent to personal jurisdiction in the state and federal courts of
the state of New York. The Company and the Holders consent to process being
served in any such suit, action or proceeding by mailing a copy thereof 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 in this Section 7(k) shall affect or limit any right to
serve process in any other manner permitted by law. The Company and the Holders
hereby agree that the prevailing party in any suit, action or proceeding arising
out of or relating to this Agreement or the Purchase Agreement, shall be
entitled to reimbursement for reasonable legal fees from the non-prevailing
party. The parties hereby waive all rights to a trial by jury.

            (l) Cumulative Remedies. The remedies provided herein are cumulative
and not exclusive of any remedies provided by law.

            (m) Severability. If any term, provision, covenant or restriction of
this Agreement is held to be invalid, illegal, void or unenforceable in any
respect, the remainder of the terms, provisions, covenants and restrictions set
forth herein shall remain in full force and effect and shall in no way be
affected, impaired or invalidated, and the parties hereto shall use their
reasonable efforts to find and employ an alternative means to achieve the same
or substantially the same result as that contemplated by such term, provision,
covenant or restriction. It is hereby stipulated and declared to be the
intention of the parties that they would have executed the remaining terms,
provisions, covenants and restrictions without including any of such that may be
hereafter declared invalid, illegal, void or unenforceable.

                                       16

            (n) Headings. 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.

            (o) Shares Held by the Company and its Affiliates. Whenever the
consent or approval of Holders of a specified percentage of Registrable
Securities is required hereunder, Registrable Securities held by the Company or
its Affiliates (other than any Holder or transferees or successors or assigns
thereof if such Holder is deemed to be an Affiliate solely by reason of its
holdings of such Registrable Securities) shall not be counted in determining
whether such consent or approval was given by the Holders of such required
percentage.

            (p) Independent Nature of the Purchaser. The Company acknowledges
that the obligations of the Purchaser under the Transaction Documents are
several and not joint with the obligations of any third party purchaser of the
Company's securities, and the Purchaser shall not be responsible in any way for
the performance of the obligations of any third party purchaser of the Company's
securities. The Company acknowledges that the decision of the Purchaser to
purchase Securities pursuant to the Transaction Documents has been made by the
Purchaser independently of any third party purchaser of the Company's
securities. Nothing contained herein or in any other Transaction Document or any
agreement of any such third party purchaser, and no action taken by the
Purchaser pursuant to any of the Transaction Documents or any such third party
purchaser pursuant thereto, shall be deemed to constitute the Purchaser and any
third party purchaser of the Company's securities as a partnership, an
association, a joint venture or any other kind of entity or group, or create a
presumption that the Purchaser and any such third party purchaser of the
Company's securities are in any way acting in concert or as a group with respect
to any matters. The Purchaser acknowledges that no third party purchaser of the
Company's securities has acted as agent for the Purchaser in connection with
making its investment hereunder and that no third party purchaser of the
Company's securities will be acting as agent of the Purchaser in connection with

                                       17
<PAGE>

monitoring its investment in the Securities or enforcing its rights under the
Transaction Documents. The Company acknowledges that the 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 third party
purchaser of the Company's securities to be joined as an additional party in any
proceeding for such purpose. To the extent that any such third party purchasers
purchase the same or similar securities as the Purchaser hereunder or on the
same or similar terms and conditions or pursuant to the same or similar
documents, all such matters are solely in the control of the Company, not the
action or decision of the Purchaser, and would be solely for the convenience of
the Company and not because it was required or requested to do so by the
Purchaser or any such third party purchaser. For clarification purposes only and
without implication that the contrary would otherwise be true, the transactions
contemplated by the Transaction Documents include only the transaction between
the Company and the Purchaser and do not include any other transaction between
the Company and any other third party purchaser of the Company's securities. The
Purchaser acknowledges that it has retained its own individual counsel with
respect to the transactions contemplated by the Transaction Documents.

                                    Exhibit A

                              Plan of Distribution

      The selling security holders and any of their pledgees, donees, assignees
and successors-in-interest may, from time to time, sell any or all of their
shares of common stock being offered under this prospectus on any stock
exchange, market or trading facility on which shares of our common stock are
traded or in private transactions. These sales may be at fixed or negotiated
prices. The selling security holders may use any one or more of the following
methods when disposing of shares:

      o     ordinary brokerage transactions and transactions in which the
            broker-dealer solicits purchasers;

      o     block trades in which the broker-dealer will attempt to sell the
            shares as agent but may position and resell a portion of the block
            as principal to facilitate the transaction;

      o     purchases by a broker-dealer as principal and resales by the
            broker-dealer for its account;

      o     an exchange distribution in accordance with the rules of the
            applicable exchange;

      o     privately negotiated transactions;

      o     to cover short sales made after the date that the registration
            statement of which this prospectus is a part is declared effective
            by the Commission;

      o     broker-dealers may agree with the selling security holders to sell a
            specified number of such shares at a stipulated price per share;

      o     a combination of any of these methods of sale; and

      o     any other method permitted pursuant to applicable law.

      The shares may also be sold under Rule 144 under the Securities Act of
1933, as amended ("Securities Act"), if available, rather than under this
prospectus. The selling security holders have the sole and absolute discretion
not to accept any purchase offer or make any sale of shares if they deem the
purchase price to be unsatisfactory at any particular time.

      The selling security holders may pledge their shares to their brokers
under the margin provisions of customer agreements. If a selling security holder
defaults on a margin loan, the broker may, from time to time, offer and sell the
pledged shares.

      Broker-dealers engaged by the selling security holders may arrange for
other broker-dealers to participate in sales. Broker-dealers may receive
commissions or discounts from the selling security holders (or, if any
broker-dealer acts as agent for the purchaser of shares, from the purchaser) in
amounts to be negotiated, which commissions as to a particular broker or dealer
may be in excess of customary commissions to the extent permitted by applicable
law.

      If sales of shares offered under this prospectus are made to
broker-dealers as principals, we would be required to file a post-effective
amendment to the registration statement of which this prospectus is a part. In
the post-effective amendment, we would be required to disclose the names of any
participating broker-dealers and the compensation arrangements relating to such
sales.

      The selling security holders and any broker-dealers or agents that are
involved in selling the shares offered under this prospectus may be deemed to be
"underwriters" within the meaning of the Securities Act in connection with these
sales. Commissions received by these broker-dealers or agents and any profit on
the resale of the shares purchased by them may be deemed to be underwriting
commissions or discounts under the Securities Act. Any broker-dealers or agents
that are deemed to be underwriters may not sell shares offered under this
prospectus unless and until we set forth the names of the underwriters and the
material details of their underwriting arrangements in a supplement to this
prospectus or, if required, in a replacement prospectus included in a
post-effective amendment to the registration statement of which this prospectus
is a part.

      The selling security holders and any other persons participating in the
sale or distribution of the shares offered under this prospectus will be subject
to applicable provisions of the Exchange Act, and the rules and regulations
under that act, including, to the extent applicable, Regulation M. These
provisions may restrict activities of, and limit the timing of purchases and
sales of any of the shares by, the selling security holders or any other person.
Furthermore, under Regulation M, to the extent applicable, persons engaged in a
distribution of securities may be prohibited from simultaneously engaging in
market making and other activities with respect to those securities for a
specified period of time prior to the commencement of such distributions,
subject to specified exceptions or exemptions. All of these limitations may
affect the marketability of the shares.

      If any of the shares of common stock offered for sale pursuant to this
prospectus are transferred other than pursuant to a sale under this prospectus,
then subsequent holders could not use this prospectus until a post-effective
amendment or prospectus supplement is filed, naming such holders. We offer no
assurance as to whether any of the selling security holders will sell all or any
portion of the shares offered under this prospectus.

      We have agreed to pay all fees and expenses we incur incident to the
registration of the shares being offered under this prospectus. However, each
selling security holder and purchaser is responsible for paying any discounts,
commissions and similar selling expenses they incur.

      We and the selling security holders have agreed to indemnify one another
against certain losses, damages and liabilities arising in connection with this
prospectus, including liabilities under the Securities Act.
