        hereto.” 

       

      2. The

        new
        Section 4.13(a):

       

      “(a) Subject
        to the terms under this Section 4.13, from the date hereof until the date

        the Debentures are no longer outstanding, upon any issuance by the Company
        or
        any of its Subsidiaries of Common Stock or Common Stock Equivalents (a

        each

        Subsequent Financing equal to the lesser of (i) 100% of the Subsequent Financing
        or (ii) the aggregate principal amount of Debentures (the “Participation

      4. The
        undersigned hereby acknowledge that sales and issuances by the Company of
        the

        Section
        4.4 of the Purchase Agreement with respect to the issuance of the New Debentures
        and the New Warrants.

       

      5. Except
        as
        specifically amended by this Amendment, the terms and conditions of the Purchase
        Agreement shall remain unchanged and in full force and effect. This Amendment
        shall become effective when executed and delivered by the Company and the
        Original Purchasers. This Amendment does not constitute a waiver of any rights
        that the Original Purchasers have to approve any offering of securities.
        This
        Amendment shall not be effective as to any New Debentures or New Purchasers
        unless the Original Purchasers shall have consented in writing to the terms
        and
        conditions of such offering at the time any such offering is made.

       

      6. This
        Amendment may be executed in one or more counterparts, each of which shall
        constitute an original, and all of which together shall constitute one and
        the
        same instrument. This Amendment may be executed and delivered by facsimile
        and
        the parties hereto agree that such facsimile execution and delivery shall
        have
        the same force and effect as delivery of an original document with original
        signatures, and that each party hereto may use such facsimile signatures
        as
        evidence of the execution and delivery of this Amendment by all parties hereto
        to the same extent that an original signature could be used.

accordance with the terms of the Notes (as defined below).

         C. Each Buyer wishes to purchase, and the Company wishes to sell, upon
the terms and conditions stated in this Agreement, (i) that aggregate principal

that:

                                       -2-

<PAGE>

              (a) NO PUBLIC SALE OR DISTRIBUTION. Such Buyer is (i) acquiring
the Notes and the Warrants and (ii) upon conversion of the Notes and exercise of
the Warrants will acquire the Conversion Shares issuable upon conversion of the
Notes and the Warrant Shares issuable upon exercise of the Warrants, for its own
account and not with a view towards, or for resale in connection with, the
public sale or distribution thereof, except pursuant to sales registered or
exempted under the 1933 Act; PROVIDED, HOWEVER, that by making the
representations herein, such Buyer does not agree to hold any of the Securities
for any minimum or other specific term and reserves the right to dispose of the
Securities at any time in accordance with or pursuant to a registration
statement or an exemption under the 1933 Act. Such Buyer is acquiring the
Securities hereunder in the ordinary course of its business. Such Buyer does not
presently have any agreement or understanding, directly or indirectly, with any
Person (as defined herein) to distribute any of the Securities.

              (b) ACCREDITED INVESTOR STATUS. Such Buyer is an "accredited
investor" as that term is defined in Rule 501(a) of Regulation D.

              (c) RELIANCE ON EXEMPTIONS. Such Buyer understands that the
Securities are being offered and sold to it in reliance on specific exemptions
from the registration requirements of United States federal and state securities
laws and that the Company is relying in part upon the truth and accuracy of, and
such Buyer's compliance with, the representations, warranties, agreements,
acknowledgments and understandings of such Buyer set forth herein in order to
determine the availability of such exemptions and the eligibility of such Buyer
to acquire the Securities.

              (d) INFORMATION. Such Buyer and its advisors, if any, have been
furnished with all materials relating to the business, finances and operations
of the Company and materials relating to the offer and sale of the Securities
which have been requested by such Buyer. Such Buyer and its advisors, if any,
have been afforded the opportunity to ask questions of the Company. Neither such
inquiries nor any other due diligence investigations conducted by such Buyer or
its advisors, if any, or its representatives shall modify, amend or affect such
Buyer's right to rely on the Company's representations and warranties contained
herein. Such Buyer understands that its investment in the Securities involves a
high degree of risk. Such Buyer has sought such accounting, legal and tax advice
as it has considered necessary to make an informed investment decision with
respect to its acquisition of the Securities.

              (e) NO GOVERNMENTAL REVIEW. Such Buyer understands that no United
States federal or state agency or any other government or governmental agency
has passed on or made any recommendation or endorsement of the Securities or the
fairness or suitability of the investment in the Securities nor have such
authorities passed upon or endorsed the merits of the offering of the
Securities.

              (f) TRANSFER OR RESALE. Such Buyer understands that except as
provided in the Registration Rights Agreement: (i) the Securities have not been
and are not being registered under the 1933 Act or any state securities laws,
and may not be offered for sale, sold, assigned or transferred unless (A)
subsequently registered thereunder, (B) such Buyer shall have delivered to the
Company an opinion of counsel, in a generally acceptable form, to the effect
that such Securities to be sold, assigned or transferred may be sold, assigned
or transferred pursuant to an exemption from such registration, or (C) such

                                      -3-

<PAGE>

Buyer provides the Company with reasonable assurance that such Securities can be
sold, assigned or transferred pursuant to Rule 144 or Rule 144A promulgated
under the 1933 Act, as amended, (or a successor rule thereto) (collectively,
"RULE 144"); (ii) any sale of the Securities made in reliance on Rule 144 may be
made only in accordance with the terms of Rule 144 and further, if Rule 144 is
not applicable, any resale of the Securities under circumstances in which the
seller (or the Person (as defined in Section 3(s)) through whom the sale is
made) may be deemed to be an underwriter (as that term is defined in the 1933
Act) may require compliance with some other exemption under the 1933 Act or the
rules and regulations of the SEC thereunder; and (iii) neither the Company nor
any other Person is under any obligation to register the Securities under the
1933 Act or any state securities laws or to comply with the terms and conditions
of any exemption thereunder. The Securities may be pledged in connection with a
bona fide margin account or other loan or financing arrangement secured by the
Securities and such pledge of Securities shall not be deemed to be a transfer,
sale or assignment of the Securities hereunder, and no Buyer effecting a pledge
of Securities shall be required to provide the Company with any notice thereof
or otherwise make any delivery to the Company pursuant to this Agreement or any
other Transaction Document (as defined in Section 3(b)), including, without
limitation, this Section 2(f).

              (g) LEGENDS. Such Buyer understands that the certificates or other
instruments representing the Notes and the Warrants and, until such time as the
resale of the Conversion Shares and the Warrant Shares have been registered
under the 1933 Act as contemplated by the Registration Rights Agreement, the
stock certificates representing the Conversion Shares and the Warrant Shares,
except as set forth below, shall bear any legend as required by the "blue sky"
laws of any state and a restrictive legend in substantially the following form
(and a stop-transfer order may be placed against transfer of such stock
certificates):

                  [NEITHER THE ISSUANCE AND SALE OF THE SECURITIES REPRESENTED
                  BY THIS CERTIFICATE NOR THE SECURITIES INTO WHICH THESE
                  SECURITIES ARE [CONVERTIBLE] [EXERCISABLE] HAVE BEEN][THE
                  SECURITIES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN]
                  REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED, OR
                  APPLICABLE STATE SECURITIES LAWS. THE SECURITIES MAY NOT BE
                  OFFERED FOR SALE, SOLD, TRANSFERRED OR ASSIGNED (I) IN THE
                  ABSENCE OF (A) AN EFFECTIVE REGISTRATION STATEMENT FOR THE
                  SECURITIES UNDER THE SECURITIES ACT OF 1933, AS AMENDED, OR
                  (B) AN OPINION OF COUNSEL, IN A GENERALLY ACCEPTABLE FORM,
                  THAT REGISTRATION IS NOT REQUIRED UNDER SAID ACT OR (II)
                  UNLESS SOLD PURSUANT TO RULE 144 OR RULE 144A UNDER SAID ACT.
                  NOTWITHSTANDING THE FOREGOING, THE SECURITIES MAY BE PLEDGED
                  IN CONNECTION WITH A BONA FIDE MARGIN ACCOUNT OR OTHER LOAN OR
                  FINANCING ARRANGEMENT SECURED BY THE SECURITIES.

                                      -4-

<PAGE>

The legend set forth above shall be removed and the Company shall issue a
certificate without such legend to the holder of the Securities upon which it is
stamped or issue to such holder by electronic delivery at the applicable balance
account at DTC (as defined below), unless otherwise required by state securities
laws, (i) such Securities as are registered for resale under the 1933 Act, (ii)
in connection with a sale, assignment or other transfer of such Securities, in
the event that such holder provides the Company with an opinion of counsel, in a
generally acceptable form, to the effect that such sale, assignment or transfer
of the Securities may be made without registration under the applicable
requirements of the 1933 Act, or (iii) in the event that such holder provides
the Company with an opinion of counsel, in a generally acceptable form, to the
effect that the Securities can be sold, assigned or transferred pursuant to Rule
144 or Rule 144A.

              (h) VALIDITY; ENFORCEMENT. This Agreement and the Registration
Rights Agreement have been duly and validly authorized, executed and delivered
on behalf of such Buyer and shall constitute the legal, valid and binding
obligations of such Buyer enforceable against such Buyer in accordance with
their respective terms, except as such enforceability may be limited by general
principles of equity or to applicable bankruptcy, insolvency, reorganization,
moratorium, liquidation and other similar laws relating to, or affecting
generally, the enforcement of applicable creditors' rights and remedies.

              (i) NO CONFLICTS. The execution, delivery and performance by such
Buyer of this Agreement and the Registration Rights Agreement, and the
consummation by such Buyer of the transactions contemplated hereby and thereby
will not (i) result in a violation of the organizational documents of such Buyer
or (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, indenture or instrument to which such Buyer is a party, or (iii)
result in a violation of any law, rule, regulation, order, judgment or decree
(including federal and state securities laws) applicable to such Buyer, except
in the case of clauses (ii) and (iii) above, for such conflicts, defaults,
rights or violations which would not, individually or in the aggregate,
reasonably be expected to have a material adverse effect on the ability of such
Buyer to perform its obligations hereunder.

              (j) RESIDENCY. Such Buyer is a resident of that jurisdiction
specified below its address on the Schedule of Buyers.

         3. REPRESENTATIONS AND WARRANTIES OF THE COMPANY.

              The Company represents and warrants to each of the Buyers that:

              (a) ORGANIZATION AND QUALIFICATION. Each of the Company and its
"SUBSIDIARIES" (which for purposes of this Agreement means any entity in which
the Company, directly or indirectly, owns any of the capital stock or holds an
equity or similar interest) are entities duly organized and validly existing in
good standing under the laws of the jurisdiction in which they are formed, and
have the requisite power and authorization to own their properties and to carry
on their business as now being conducted. Each of the Company and its
Subsidiaries is duly qualified as a foreign entity to do business and is in good
standing in every jurisdiction in which its ownership of property or the nature
of the business conducted by it makes such qualification necessary, except to
the extent that the failure to be so qualified or be in good standing would not
have a Material Adverse Effect. As used in this Agreement, "MATERIAL ADVERSE
EFFECT" means any material adverse effect on the business, properties, assets,

                                      -5-

operations, results of operations, condition (financial or otherwise) or
prospects of the Company and its Subsidiaries, taken as a whole, or on the
transactions contemplated hereby and the other Transaction Documents or by the
agreements and instruments to be entered into in connection herewith or
therewith, or on the authority or ability of the Company to perform its
obligations under the Transaction Documents. The Company has no Subsidiaries
except as set forth on SCHEDULE 3(a).

              (b) AUTHORIZATION; ENFORCEMENT; VALIDITY. The Company has the
requisite power and authority to enter into and perform its obligations under
this Agreement, the Notes, the Registration Rights Agreement, the Security
Documents, the Irrevocable Transfer Agent Instructions (as defined in Section
5(b) below), the Warrants, and each of the other agreements entered into by the
parties hereto in connection with the transactions contemplated by this
Agreement (collectively, the "TRANSACTION DOCUMENTS") and, to issue the
Securities in accordance with the terms hereof and thereof. The execution and
delivery of the Transaction Documents by the Company and the consummation by the
Company of the transactions contemplated hereby and thereby, including, without
limitation, the issuance of the Notes and the Warrants, the reservation for
issuance and the issuance of the Conversion Shares issuable upon conversion of
the Notes and the reservation for issuance and issuance of Warrant Shares
issuable upon exercise of the Warrants have been duly authorized by the
Company's Board of Directors and no further consent, or authorization is
required by the Company, its Board of Directors or its stockholders. This
Agreement and the other Transaction Documents of even date herewith have been
duly executed and delivered by the Company, and constitute the legal, valid and
binding obligations of the Company, enforceable against the Company in
accordance with their respective terms, except as such enforceability may be
limited by general principles of equity or applicable bankruptcy, insolvency,
reorganization, moratorium, liquidation or similar laws relating to, or
affecting generally, the enforcement of applicable creditors' rights and
remedies.

              (c) ISSUANCE OF SECURITIES. The issuance of the Notes and the
Warrants are duly authorized and are free from all taxes, liens and charges with
respect to the issue thereof. As of the Closing, a number of shares of Common
Stock shall have been duly authorized and reserved for issuance which equals at
least 130% of the sum of the maximum number of shares of Common Stock issuable
(i) upon conversion of the Notes and (ii) upon exercise of the Warrants. Upon
conversion in accordance with the Notes or exercise in accordance with the
Warrants, as the case may be, the Conversion Shares and the Warrant Shares,
respectively, will be validly issued, fully paid and nonassessable and free from
all preemptive or similar rights, taxes, liens and charges with respect to the
issue thereof, with the holders being entitled to all rights accorded to a
holder of Common Stock. The offer and issuance by the Company of the Securities
is exempt from registration under the 1933 Act.

              (d) 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 (including, without limitation, the
issuance of the Notes and the Warrants, and the reservation for issuance and
issuance of the Conversion Shares and the Warrant Shares) will not (i) result in
a violation of the Articles of Incorporation (as defined in Section 3(r)) of the
Company or any of its Subsidiaries, any capital stock of the Company or Bylaws
(as defined in Section 3(r)) of the Company or any of its Subsidiaries, (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

                                      -6-

<PAGE>

termination, amendment, acceleration or cancellation of, any agreement,
indenture or instrument to which the Company or any of its Subsidiaries is a
party, or (iii) result in a violation of any law, rule, regulation, order,
judgment or decree (including federal and state securities laws and regulations
and the rules and regulations of the OTC Bulletin Board (the "PRINCIPAL
MARKET")) 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 the case of clauses (ii) and (iii) above, for such
conflicts, defaults, rights or violations which would not, individually or in
the aggregate, reasonably be expected to have a Material Adverse Effect.

              (e) CONSENTS. Neither the Company nor any of its Subsidiaries is
required to obtain any consent, authorization or order of, or make any filing or
registration with, any court, governmental agency or any regulatory or
self-regulatory agency or any other Person in order for it to execute, deliver
or perform any of its obligations under or contemplated by the Transaction
Documents, in each case in accordance with the terms hereof or thereof. All
consents, authorizations, orders, filings and registrations which the Company is
required to obtain pursuant to the preceding sentence have been obtained or
effected on or prior to the Closing Date, and the Company and its Subsidiaries
are unaware of any facts or circumstances which might prevent the Company from
obtaining or effecting any of the registration, application or filings pursuant
to the preceding sentence. The Company is not in violation of the listing
requirements of the Principal Market and has no knowledge of any facts which
would reasonably lead to delisting or suspension of the Common Stock in the
foreseeable future.

              (f) ACKNOWLEDGMENT REGARDING BUYER'S PURCHASE OF SECURITIES. The
Company acknowledges and agrees that each Buyer is acting solely in the capacity
of arm's length purchaser with respect to the Transaction Documents and the
transactions contemplated hereby and thereby and that no Buyer is (i) an officer
or director of the Company, (ii) to the Company's knowledge, an "affiliate" of
the Company (as defined in Rule 144) or (iii) to the knowledge of the Company, a
"beneficial owner" of more than 10% of the shares of Common Stock (as defined
for purposes of Rule 13d-3 of the Securities Exchange Act of 1934, as amended
(the "1934 ACT")). The Company further acknowledges that no Buyer is acting as a
financial advisor or fiduciary of the Company (or in any similar capacity) with
respect to the Transaction Documents and the transactions contemplated hereby
and thereby, and any advice given by a Buyer or any of its representatives or
agents in connection with the Transaction Documents and the transactions
contemplated hereby and thereby is merely incidental to such Buyer's purchase of
the Securities. The Company further represents to each Buyer that the Company's
decision to enter into the Transaction Documents has been based solely on the
independent evaluation by the Company and its representatives.

              (g) NO GENERAL SOLICITATION; PLACEMENT AGENT'S FEES. 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) in connection with the offer or sale of the
Securities. The Company shall be responsible for the payment of any placement
agent's fees, financial advisory fees, or brokers' commissions (other than for
persons engaged by any Buyer or its investment advisor) relating to or arising
out of the transactions contemplated hereby. The Company shall pay, and hold
each Buyer harmless against, any liability, loss or expense (including, without
limitation, attorney's fees and out-of-pocket expenses) arising in connection
with any such claim. The Company acknowledges that it has engaged Montgomery &
Co., LLC, as placement agent (the "PLACEMENT AGENT") in connection with the sale
of the Securities. Other than the Placement Agent, the Company has not engaged
any placement agent or other agent in connection with the sale of the
Securities.

<PAGE>

              (h) NO INTEGRATED OFFERING. None of the Company, its Subsidiaries,
any of their affiliates, and any Person acting on 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 require registration of the
issuance of any of the Securities under the 1933 Act or cause this offering of
the Securities to be integrated with prior offerings by the Company for purposes
of the 1933 Act or any applicable stockholder approval provisions, including,
without limitation, under the rules and regulations of any exchange or automated
quotation system on which any of the securities of the Company are listed or
designated. None of the Company, its Subsidiaries, their affiliates and any
Person acting on their behalf will take any action or steps referred to in the
preceding sentence that would require registration of the issuance of any of the
Securities under the 1933 Act or cause the offering of the Securities to be
integrated with other offerings.

              (i) DILUTIVE EFFECT. The Company understands and acknowledges that
the number of Conversion Shares issuable upon conversion of the Notes and the
Warrant Shares issuable upon exercise of the Warrants will increase in certain
circumstances. The Company further acknowledges that its obligation to issue
Conversion Shares upon conversion of the Notes in accordance with this Agreement
and the Notes and its obligation to issue the Warrant Shares upon exercise of
the Warrants in accordance with this Agreement and the Warrants, in each case,
is absolute and unconditional regardless of the dilutive effect that such
issuance may have on the ownership interests of other stockholders of the
Company.

              (j) APPLICATION OF TAKEOVER PROTECTIONS; RIGHTS AGREEMENT. The
Company and its board of directors have taken all necessary action, if any, in
order to render inapplicable any control share acquisition, business
combination, poison pill (including any distribution under a rights agreement)
or other similar anti-takeover provision under the Articles of Incorporation or
the laws of the jurisdiction of its formation which is or could become
applicable to any Buyer as a result of the transactions contemplated by this
Agreement, including, without limitation, the Company's issuance of the
Securities and any Buyer's ownership of the Securities. The Company has not
adopted a stockholder rights plan or similar arrangement relating to
accumulations of beneficial ownership of Common Stock or a change in control of
the Company.

              (k) SEC DOCUMENTS; FINANCIAL STATEMENTS. Except as disclosed in
SCHEDULE 3(k), during the two (2) years prior to the date hereof, the Company

1934 Act (all of the foregoing filed prior to the date hereof and all exhibits
included therein and financial statements, notes and schedules thereto and
documents incorporated by reference therein being hereinafter referred to as the
"SEC DOCUMENTS"). The Company has delivered to the Buyers or their respective
representatives true, correct and complete copies of the SEC Documents not
available on the EDGAR system. As of their respective dates or as a result of
subsequent amendment or modification prior to the date hereof, the SEC Documents
complied in all material respects with the requirements of the 1934 Act and the
rules and regulations of the SEC promulgated thereunder applicable to the SEC

                                      -8-

<PAGE>

Documents, and none of the SEC Documents, as amended or modified, at the time
they were filed with the SEC or as a result of subsequent amendment or
modification prior to the date hereof, contained any untrue statement of a
material fact or omitted to state a material fact required to be stated therein
or necessary in order to make the statements therein, in the 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 SEC Documents
complied as to form in all material respects with applicable accounting
requirements and the published rules and regulations of the SEC with respect
thereto. Such financial statements have been prepared in accordance with
generally accepted accounting principles, consistently applied, 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 exclude footnotes or may be condensed or
summary statements) and fairly present in all material respects the financial
position of the Company as of the dates thereof and the results of its
operations and cash flows for the periods then ended (subject, in the case of
unaudited statements, to normal year-end audit adjustments). No other
information provided by or on behalf of the Company to the Buyers which is not
included in the SEC Documents, including, without limitation, information
referred to in Section 2(d) of this Agreement, contains any untrue statement of
a material fact or omits to state any material fact necessary in order to make
the statements therein, in the light of the circumstance under which they are or
were made, not misleading.

              (l) ABSENCE OF CERTAIN CHANGES. Except as disclosed in SCHEDULE
3(l), since December 31, 2006, there has been no material adverse change and no
material adverse development in the business, properties, operations, condition

individually or in the aggregate, in excess of $100,000 outside of the ordinary
course of business or (iii) had capital expenditures, individually or in the

protection pursuant to any bankruptcy law nor does the Company have any
knowledge or reason to believe that its creditors intend to initiate involuntary

reasonably lead a creditor to do so. The Company is not as of the date hereof
after elimination of the debt owing to the Buyers, and after giving effect to
the transactions contemplated hereby to occur at the Closing, will not be
Insolvent (as defined below). For purposes of this Section 3(l), "INSOLVENT"
means with respect to any Person, (i) the present fair saleable value of such
Person's assets is less than the amount required to pay such Person's total
Indebtedness (as defined in Section 3(s)), (ii) such Person is unable to pay its
debts and liabilities, subordinated, contingent or otherwise, as such debts and
liabilities become absolute and matured, (iii) the Company intends to incur or
believes that it will incur debts that would be beyond its ability to pay as
such debts mature or (iv) such Person has unreasonably small capital with which
to conduct the business in which it is engaged as such business is now conducted
and is proposed to be conducted.

              (m) NO UNDISCLOSED EVENTS, LIABILITIES, DEVELOPMENTS OR
CIRCUMSTANCES. Except as contemplated by this Agreement or the Transaction
Documents, no event, liability, development or circumstance has occurred or
currently exists with respect to the Company, its Subsidiaries or their
respective business, properties, prospects, operations or financial condition,
that would be required to be disclosed by the Company under applicable
securities laws on a registration statement on Form SB-2 filed with the SEC
relating to an issuance and sale by the Company of its Common Stock and which
has not been publicly announced.

ordinance, rule or regulation applicable to the Company or its Subsidiaries, and
neither the Company nor any of its Subsidiaries will conduct its business in

not, individually or in the aggregate, have a Material Adverse Effect. Without
limiting the generality of the foregoing, the Company is not in violation of any
of the rules, regulations or requirements of the Principal Market and has no
knowledge of any facts or circumstances which would reasonably lead to delisting
or suspension of the Common Stock by the Principal Market in the foreseeable

businesses, except where the failure to possess such certificates,
authorizations or permits would not have, individually or in the aggregate, a
Material Adverse Effect, and neither the Company nor any such Subsidiary has
received any notice of proceedings relating to the revocation or modification of
any such certificate, authorization or permit.

              (o) FOREIGN CORRUPT PRACTICES. Neither the Company, nor any of its

outstanding Indebtedness (as defined below), (ii) is a party to any contract,

other party(ies) to such contract, agreement or instrument would result in a
Material Adverse Effect, (iii) is in violation of any term of or in default
under any contract, agreement or instrument relating to any Indebtedness, except
where such violations and defaults would not result, individually or in the

agreement or instrument relating to any Indebtedness, the performance of which,
in the judgment of the Company's officers, has or is expected to have a Material

"INDEBTEDNESS" of any Person means, without duplication (A) all indebtedness for
borrowed money, (B) all obligations issued, undertaken or assumed as the
deferred purchase price of property or services (other than trade payables

indebtedness created or arising under any conditional sale or other title

which the holder of such Indebtedness has an existing right, contingent or
otherwise, to be secured by) any mortgage, lien, pledge, charge, security
interest or other encumbrance upon or in any property or assets (including
accounts and contract rights) owned by any Person, even though the Person which
owns such assets or property has not assumed or become liable for the payment of
such indebtedness, and (H) all Contingent Obligations in respect of indebtedness
or obligations of others of the kinds referred to in clauses (A) through (G)
above; (y) "CONTINGENT OBLIGATION" means, as to any Person, any direct or
indirect liability, contingent or otherwise, of that Person with respect to any

primary purpose or intent of the Person incurring such liability, or the primary
effect thereof, is to provide assurance to the obligee of such liability that
such liability will be paid or discharged, or that any agreements relating
thereto will be complied with, or that the holders of such liability will be
protected (in whole or in part) against loss with respect thereto; and (z)
"PERSON" means an individual, a limited liability company, a partnership, a
joint venture, a corporation, a trust, an unincorporated organization and a

the knowledge of the Company, threatened against or affecting the Company or any
of its Subsidiaries, the Common Stock or the capital stock of any of the
Company's Subsidiaries or any of the Company's or its Subsidiaries' officers or
directors in their capacities as such, except as set forth in SCHEDULE 3(t) or

              (u) INSURANCE. The Company and each of its Subsidiaries are
insured by insurers of recognized financial responsibility against such losses
and risks and in such amounts as management of the Company believes to be
prudent and customary in the businesses in which the Company and its
Subsidiaries are engaged. Neither the Company nor any such Subsidiary has been
refused any insurance coverage sought or applied for and neither the Company nor
any such Subsidiary has any reason to believe that it will not be able to renew
its existing insurance coverage as and when such coverage expires or to obtain
similar coverage from similar insurers as may be necessary to continue its
business at a cost that would not have a Material Adverse Effect.

              (v) EMPLOYEE RELATIONS. (i) Neither the Company nor any of its
Subsidiaries is a party to any collective bargaining agreement or employs any
member of a union. The Company and its Subsidiaries believe that their relations
with their employees are good. No executive officer of the Company or any of its
Subsidiaries has notified the Company or any such Subsidiary that such officer
intends to leave or otherwise terminate such officer's employment with the
Company or any such Subsidiary. No executive officer of the Company or any of
its Subsidiaries, to the knowledge of the Company, is, or is now expected to be,
in violation of any material term of any employment contract, confidentiality,
disclosure or proprietary information agreement, non-competition agreement, or
any other contract or agreement or any restrictive covenant, and the continued
employment of each such executive officer does not subject the Company or any of
its Subsidiaries to any liability with respect to any of the foregoing matters.

                   (ii) The Company and its Subsidiaries are in compliance with
all applicable federal, state, local and foreign laws and regulations respecting
labor, employment and employment practices and benefits, terms and conditions of
employment and wages and hours, except where failure to be in compliance would
not, either individually or in the aggregate, reasonably be expected to result
in a Material Adverse Effect.

              (w) TITLE. Except as set forth on SCHEDULE 3(w), the Company and
its Subsidiaries have good and marketable title in fee simple to all real
property and good and marketable title to all personal property owned by them
which is material to the business of the Company and its Subsidiaries, in each
case free and clear of all liens, encumbrances and defects except such as do not
materially affect the value of such property and do not interfere with the use
made and proposed to be made of such property by the Company and any of its
Subsidiaries. Any real property, buildings and facilities held under lease by
the Company and any of its Subsidiaries are held by them under valid, subsisting
and enforceable leases with such exceptions as are not material and do not
interfere with the use made and proposed to be made of such property, buildings
and facilities by the Company and its Subsidiaries.

own or possess adequate rights or licenses to use all trademarks, trade names,
service marks, service mark registrations, service names, patents, patent
rights, copyrights, inventions, licenses, approvals, governmental
authorizations, trade secrets and other intellectual property rights
("INTELLECTUAL PROPERTY Rights") necessary to conduct their respective
businesses as now conducted. Except as set forth in SCHEDULE 3(x), none of the
Intellectual Property Rights of the Company or any Subsidiary have expired or
terminated, or are expected to expire or terminate, within three years from the
date of this Agreement. The Company does not have any knowledge of any
infringement by the Company or its Subsidiaries of Intellectual Property Rights
of others. There is no claim, action or proceeding being made or brought, or to
the knowledge of the Company, being threatened, against the Company or its
Subsidiaries regarding its Intellectual Property Rights. The Company is unaware
of any facts or circumstances which would be reasonably expected to give rise to
any of the foregoing infringements or claims, actions or proceedings. The
Company and its Subsidiaries have taken reasonable security measures to protect
the secrecy, confidentiality and value of all of their intellectual properties.

              (y) ENVIRONMENTAL LAWS. The Company and its Subsidiaries (i) are
in compliance with any and all applicable Environmental Laws (as hereinafter
defined), (ii) have received all permits, licenses or other approvals required
of them under applicable Environmental Laws to conduct their respective
businesses and (iii) are in compliance with all terms and conditions of any such
permit, license or approval where, in each of the foregoing clauses (i), (ii)
and (iii), the failure to so comply could be reasonably expected to have,
individually or in the aggregate, a Material Adverse Effect. The term
"ENVIRONMENTAL LAWS" means all federal, state, local or foreign laws relating to
pollution or protection of human health or the environment (including, without
limitation, ambient air, surface water, groundwater, land surface or subsurface
strata), including, without limitation, laws relating to emissions, discharges,
releases or threatened releases of chemicals, pollutants, contaminants, or toxic
or hazardous substances or wastes (collectively, "HAZARDOUS MATERIALS") into the
environment, or otherwise relating to the manufacture, processing, distribution,
use, treatment, storage, disposal, transport or handling of Hazardous Materials,
as well as all authorizations, codes, decrees, demands or demand letters,
injunctions, judgments, licenses, notices or notice letters, orders, permits,
plans or regulations issued, entered, promulgated or approved thereunder.

              (z) SUBSIDIARY RIGHTS. Except as set forth in SCHEDULE 3(z), the
Company or one of its Subsidiaries has the unrestricted right to vote, and
(subject to limitations imposed by applicable law) to receive dividends and
distributions on, all capital securities of its Subsidiaries as owned by the
Company or such Subsidiary.

              (aa) INVESTMENT COMPANY STATUS. The Company is not, and upon
consummation of the sale of the Securities will not be, an "investment company,"
a company controlled by an "investment company" or an "affiliated person" of, or
"promoter" or "principal underwriter" for, an "investment company" as such terms
are defined in the Investment Company Act of 1940, as amended.

              (bb) TAX STATUS. The Company and each of its Subsidiaries (i) has
made or filed all foreign, federal and state income and all other tax returns,
reports and declarations required by any jurisdiction to which it is subject,
(ii) has paid all taxes and other governmental assessments and charges that are
material in amount, shown or determined to be due on such returns, reports and
declarations, except those being contested in good faith and (iii) has set aside
on its books provision reasonably adequate for the payment of all taxes for
periods subsequent to the periods to which such returns, reports or declarations
apply. There are no unpaid taxes in any material amount claimed to be due by the
taxing authority of any jurisdiction, and the officers of the Company know of no
basis for any such claim.

              (cc) INTERNAL ACCOUNTING AND DISCLOSURE CONTROLS. 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 generally accepted accounting principles and to
maintain asset and liability accountability, (iii) access to assets or
incurrence of liabilities is permitted only in accordance with management's
general or specific authorization and (iv) the recorded accountability for
assets and liabilities is compared with the existing assets and liabilities at
reasonable intervals and appropriate action is taken with respect to any
difference. The Company maintains disclosure controls and procedures (as such
term is defined in Rule 13a-14 under the 1934 Act) that are effective in
ensuring that information required to be disclosed by the Company in the reports
that it files or submits under the 1934 Act is recorded, processed, summarized
and reported, within the time periods specified in the rules and forms of the
SEC, including, without limitation, controls and procedures designed to ensure
that information required to be disclosed by the Company in the reports that it
files or submits under the 1934 Act is accumulated and communicated to the
Company's management, including its principal executive officer or officers and
its principal financial officer or officers, as appropriate, to allow timely
decisions regarding required disclosure.

              (dd) OFF BALANCE SHEET ARRANGEMENTS. There is no transaction,
arrangement, or other relationship between the Company and an unconsolidated or
other off balance sheet entity that is required to be disclosed by the Company
in its SEC Documents and is not so disclosed or that otherwise would be
reasonably likely to have a Material Adverse Effect.

              (ee) RANKING OF NOTES. Except as set forth on SCHEDULE 3(ee), no
Indebtedness of the Company is senior to or ranks PARI PASSU with the Notes in
right of payment, whether with respect of payment of redemptions, interest,
damages or upon liquidation or dissolution or otherwise.

              (ff) FORM SB-2 ELIGIBILITY. The Company is eligible to register
the Conversion Shares and the Warrant Shares for resale by the Buyers using Form
SB-2 promulgated under the 1933 Act, subject to the limitations of Rule 415 of
the 1933 Act.

              (gg) TRANSFER TAXES. On the Closing Date, all stock transfer or
other taxes (other than income or similar taxes) which are required to be paid
in connection with the sale and transfer of the Securities to be sold to each
Buyer hereunder will be, or will have been, fully paid or provided for by the
Company, and all applicable laws imposing such taxes will be or will have been
complied with, except where the failure to comply would not reasonably be
expected to have a Material Adverse Effect.

              (hh) MANIPULATION OF PRICE. The Company has not, and to its
knowledge no one acting on its behalf has, (i) taken, directly or indirectly,
any action designed to cause or to result in the stabilization or manipulation
of the price of any security of the Company to facilitate the sale or resale of
any of the Securities, (ii) other than the Placement Agent, sold, bid for,
purchased, or paid any compensation for soliciting purchases of, any of the
Securities, or (iii) other than the Placement Agent, paid or agreed to pay to
any person any compensation for soliciting another to purchase any other
securities of the Company.

              (ii) ACKNOWLEDGEMENT REGARDING BUYERS' TRADING ACTIVITY. Except
pursuant to Section 4(r) hereto, it is understood and acknowledged by the
Company (i) that none of the Buyers have been asked to agree, nor has any Buyer
agreed, to desist from purchasing or selling, long and/or short, securities of
the Company, or "derivative" securities based on securities issued by the
Company or to hold the Securities for any specified term (except as to the SEC
position that short sales "against the box" prior to the effective date of a
registration statement may not be covered with shares registered under such
registration statement); (ii) that any Buyer, and counter parties in
"derivative" transactions to which any such Buyer is a party, directly or
indirectly, presently may have a "short" position in the Common Stock, and (iii)
that each Buyer shall not be deemed by the Company to have any affiliation with
or control over any arm's length counter-party in any "derivative" transaction.
The Company further understands and acknowledges that (a) one or more Buyers may
engage in hedging and/or trading activities at various times during the period
that the Securities are outstanding, including, without limitation, during the
periods that the value of the Conversion Shares and the Warrant Shares
deliverable with respect to Securities are being determined and (b) such hedging
and/or trading activities, if any, can reduce the value of the existing
stockholders' equity interest in the Company both at and after the time the
hedging and/or trading activities are being conducted. The Company acknowledges
that such aforementioned hedging and/or trading activities do not constitute a
breach of this Agreement, the Notes, the Warrants or any of the documents
executed in connection herewith.

              (jj) U.S. REAL PROPERTY HOLDING CORPORATION. The Company is not,
nor has ever been, a U.S. real property holding corporation within the meaning
of Section 897 of the Internal Revenue Code of 1986, as amended, and the Company
shall so certify upon any Buyer's request.

              (kk) NO ADDITIONAL AGREEMENTS. The Company does not have any
agreement or understanding with any Buyer with respect to the transactions
contemplated by the Transaction Documents other than as specified in the
Transaction Documents.

              (ll) BANK HOLDING COMPANY ACT. Neither the Company nor any of its
Subsidiaries or affiliates is subject to the Bank Holding Company Act of 1956,
as amended (the "BHCA") and to regulation by the Board of Governors of the
Federal Reserve System (the "Federal Reserve"). Neither the Company nor any of
its Subsidiaries or affiliates owns or controls, directly or indirectly, five
percent or more of the outstanding shares of any class of voting securities or
twenty-five percent or more of the total equity of a bank or any entity that is
subject to the BHCA and to regulation by the Federal Reserve. Neither the
Company nor any of its Subsidiaries or affiliates exercises a controlling
influence over the management or policies of a bank or any entity that is
subject to the BHCA and to regulation by the Federal Reserve.

              (mm) DISCLOSURE. The Company confirms that neither it, nor to the
Company's knowledge, any other Person acting on its behalf has provided any of
the Buyers or their agents or counsel with any information that constitutes or
could reasonably be expected to constitute material, nonpublic information. The
Company understands and confirms that each of the Buyers will rely on the
foregoing representations in effecting transactions in securities of the
Company. All disclosure provided by the Company, its Subsidiaries, its officers
or directors, its agents or its counsel to the Buyers regarding the Company, its
business and the transactions contemplated hereby, including the Schedules to
this Agreement, is true and correct and does not contain any untrue statement of
a material fact or omit to state any material fact necessary in order to make
the statements made therein, in the light of the circumstances under which they
were made, not misleading. Each press release issued by the Company during the
twelve (12) months preceding the date of this Agreement did not at the time of
release 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 the light of the circumstances under which they are made,
not misleading. No event or circumstance has occurred or information exists with
respect to the Company or any of its Subsidiaries or its or their business,
properties, prospects, operations or financial conditions, 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, except
where the failure to make any such filing or report would not have a Material
Adverse Effect.

         4. COVENANTS.

              (a) BEST EFFORTS. Each party shall use its best efforts timely to
satisfy each of the conditions to be satisfied by it as provided in Sections 6
and 7 of this Agreement.

              (b) FORM D AND BLUE SKY. The Company agrees to file a Form D with
respect to the Securities as required under Regulation D and to provide a copy
thereof to each Buyer reasonably promptly after such filing. The Company shall,
reasonably promptly (and in no event later than 15 days) after the Closing Date,
take such action as the Company shall reasonably determine is necessary (taking
into account The National Securities Markets Improvement Act of 1996, as
amended), in order to obtain an exemption for or to qualify the Securities for
sale to the Buyers at the Closing pursuant to this Agreement under applicable
securities or "Blue Sky" laws of the states of the United States (or to obtain
an exemption from such qualification), and shall provide evidence of any such
action so taken to the Buyers reasonably promptly after such filing. The Company
shall make all filings and reports relating to the offer and sale of the
Securities required under applicable securities or "Blue Sky" laws of the states
of the United States following the Closing Date. The Company shall have no
obligations with respect to the securities laws of any jurisdiction outside of
the United States, regardless of the foreign residence of such Buyer.

              (c) REPORTING STATUS. Until the date on which the Investors (as
defined in the Registration Rights Agreement) shall have sold all the Conversion
Shares and Warrant Shares and none of the Notes or Warrants is outstanding (the
"REPORTING PERIOD"), the Company shall file all reports required to be filed
with the SEC pursuant to the 1934 Act, and the Company shall not terminate its
status as an issuer required to file reports under the 1934 Act even if the 1934
Act or the rules and regulations thereunder would otherwise permit such
termination.

              (d) USE OF PROCEEDS. The Company will use the proceeds from the
sale of the Securities as set forth on Schedule 4(d).

              (e) FINANCIAL INFORMATION. The Company agrees to send the
following to each Investor (as defined in the Registration Rights Agreement)
during the Reporting Period (i) unless the following are filed with the SEC
through EDGAR and are available to the public through the EDGAR system, within
one (1) Business Day after the filing thereof with the SEC, a copy of its Annual
Reports on Form 10-K or 10-KSB, any Quarterly Report on Form 10-Q or 10-QSB, any
Current Reports on Form 8-K and any registration statements (other than on Form
S-8) or amendments filed pursuant to the 1933 Act, (ii) on the same day as the
release thereof, facsimile or e-mailed copies of all press releases issued by
the Company or any of its Subsidiaries, and (iii) copies of any notices and
other information made available or given to the stockholders of the Company
generally, contemporaneously with the making available or giving thereof to the
stockholders. As used herein, "BUSINESS DAY" means any day other than Saturday,
Sunday or other day on which commercial banks in The City of New York are
authorized or required by law to remain closed.

              (f) LISTING. The Company shall promptly secure the listing of all
of the Registrable Securities (as defined in the Registration Rights Agreement)
upon the Principal Market and each national securities exchange and automated
quotation system, if any, upon which the Common Stock is then listed (subject to
official notice of issuance) and shall thereafter maintain such listing of all
Registrable Securities from time to time issuable under the terms of the
Transaction Documents. The Company shall maintain the Common Stock's
authorization for quotation on the Principal Market. Neither the Company nor any
of its Subsidiaries shall take any action which would be reasonably expected to
result in the delisting or suspension of the Common Stock on the Principal
Market. The Company shall pay all fees and expenses in connection with
satisfying its obligations under this Section 4(f).

              (g) FEES. The Company shall reimburse each Buyer or its
designee(s) (in addition to any other expense amounts paid to any Buyer prior to
the date of this Agreement) for all reasonable costs and expenses incurred in
connection with the transactions contemplated by the Transaction Documents
(including all reasonable legal fees and disbursements in connection therewith,
documentation and implementation of the transactions contemplated by the
Transaction Documents and due diligence in connection therewith), which amount
shall be withheld by such Buyer from its Purchase Price at the Closing. The
Company shall be responsible for the payment of any placement agent's fees,
financial advisory fees, or broker's commissions (other than for Persons engaged
by any Buyer) relating to or arising out of the transactions contemplated
hereby, including, without limitation, any fees or commissions payable to the
Placement Agent. The Company shall pay, and hold each Buyer harmless against,
any liability, loss or expense (including, without limitation, reasonable
attorney's fees and out-of-pocket expenses) arising in connection with any claim
relating to any such payment, other than for Persons engaged by any Buyer.
Except as otherwise set forth in the Transaction Documents, each party to this
Agreement shall bear its own expenses in connection with the sale of the
Securities to the Buyers.

              (h) PLEDGE OF SECURITIES. The Company acknowledges and agrees that
the Securities may be pledged by an Investor (as defined in the Registration
Rights Agreement) in connection with a bona fide margin agreement or other loan
or financing arrangement that is secured by the Securities. The pledge of
Securities shall not be deemed to be a transfer, sale or assignment of the
Securities hereunder, and no Investor effecting a pledge of Securities shall be
required to provide the Company with any notice thereof or otherwise make any
delivery to the Company pursuant to this Agreement or any other Transaction
Document, including, without limitation, Section 2(f) hereof; provided that an
Investor and its pledgee shall be required to comply with the provisions of
Section 2(f) hereof in order to effect a sale, transfer or assignment of
Securities to such pledgee. The Company hereby agrees to execute and deliver
such documentation as a pledgee of the Securities may reasonably request in
connection with a pledge of the Securities to such pledgee by an Investor.

              (i) DISCLOSURE OF TRANSACTIONS AND OTHER MATERIAL INFORMATION. On
or before 8:30 a.m., New York City time, on the first Business Day following the
date of this Agreement, the Company shall issue a press release and file a
Current Report on Form 8-K describing the terms of the transactions contemplated
by the Transaction Documents in the form required by the 1934 Act and attaching
the material Transaction Documents (including, without limitation, this
Agreement, the form of the Notes, the form of Warrant, and the form of the
Registration Rights Agreement), as exhibits to such filing (including all
attachments, the "8-K FILING"). From and after the filing of the 8-K Filing with
the SEC, no Buyer shall be in possession of any material, nonpublic information
received from the Company, any of its Subsidiaries or any of their respective
officers, directors, employees or agents, that is not disclosed in the 8-K
Filing. The Company shall not, and shall cause each of its Subsidiaries and its
and each of their respective officers, directors, employees and agents, not to,
provide any Buyer with any material, nonpublic information regarding the Company
or any of its Subsidiaries from and after the filing of the 8-K Filing with the
SEC without the express written consent of such Buyer. If a Buyer has, or
believes it has, received any such material, nonpublic information regarding the
Company or any of its Subsidiaries, it shall promptly provide the Company with
written notice thereof. The Company shall, within five (5) Trading Days of
receipt of such notice, make public disclosure of such material, nonpublic
information. In the event of a breach of the foregoing covenant by the Company,
any of its Subsidiaries, or any of its or their respective officers, directors,
employees and agents, in addition to any other remedy provided herein or in the
Transaction Documents, a Buyer shall have the right to make a public disclosure,
in the form of a press release, public advertisement or otherwise, of such
material, nonpublic information without the prior approval by the Company, its
Subsidiaries, or any of its or their respective officers, directors, employees
or agents. No Buyer shall have any liability to the Company, its Subsidiaries,
or any of its or their respective officers, directors, employees, stockholders
or agents for any such disclosure, except where, as a result of the willful
misconduct or gross negligence of such Buyer, any such disclosure contains an
untrue statement of a material fact or omits 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. Subject
to the foregoing, neither the Company, its Subsidiaries nor any Buyer shall
issue any press releases or any other public statements with respect to the
transactions contemplated hereby; provided, however, that the Company shall be
entitled, without the prior approval of any Buyer, to make any press release or
other public disclosure with respect to such transactions (i) in substantial
conformity with the 8-K Filing and contemporaneously therewith and (ii) as is
required by applicable law and regulations (provided that in the case of clause
(i) each Buyer shall be consulted by the Company in connection with any such
press release or other public disclosure prior to its release). Without the
prior written consent of any applicable Buyer, and except as contemplated by the
prior subsection (i) or as required by applicable law or regulation, neither the
Company nor any of its Subsidiaries or affiliates shall disclose the name of
such Buyer in any filing, announcement, release or otherwise.

              (j) RESTRICTION ON REDEMPTION AND CASH DIVIDENDS. So long as any
Notes are outstanding, the Company shall not, directly or indirectly, redeem, or
declare or pay any cash dividend or distribution on, the Common Stock without
the prior express written consent of the holders of Notes representing not less
than a majority of the aggregate principal amount of the then outstanding Notes.

              (k) ADDITIONAL NOTES; VARIABLE SECURITIES; DILUTIVE ISSUANCES. So
long as any Buyer beneficially owns any Securities, the Company will not issue
any Notes other than to the Buyers as contemplated hereby and the Company shall
not issue any other securities that would cause a breach or default under the
Notes. For so long as any Notes or Warrants remain outstanding, the Company
shall not, in any manner, issue or sell any rights, warrants or options to
subscribe for or purchase Common Stock or directly or indirectly convertible
into or exchangeable or exercisable for Common Stock at a price which varies or
may vary with the market price of the Common Stock, including by way of one or
more reset(s) to any fixed price unless the conversion, exchange or exercise
price of any such security cannot be less than the then applicable Conversion
Price (as defined in the Notes) with respect to the Common Stock into which any
Note is convertible or the then applicable Exercise Price (as defined in the
Warrants) with respect to the Common Stock into which any Warrant is
exercisable. For so long as any Notes or Warrants remain outstanding, the
Company shall not, in any manner, enter into or affect any Dilutive Issuance (as
defined in the Notes) if the effect of such Dilutive Issuance is to cause the
Company to be required to issue upon conversion of any Note or exercise of any
Warrant any shares of Common Stock in excess of that number of shares of Common
Stock which the Company may issue upon conversion of the Notes and exercise of
the Warrants without breaching the Company's obligations under the rules or
regulations of the Principal Market or any applicable Eligible Market (as
defined in the Registration Rights Agreement).

              (l) CORPORATE EXISTENCE. So long as any Buyer beneficially owns
any Securities, the Company shall not be party to any Fundamental Transaction
(as defined in the Notes) unless the Company is in compliance with the
applicable provisions governing Fundamental Transactions set forth in the Notes
and the Warrants.

              (m) RESERVATION OF SHARES. So long as any Buyer owns any
Securities, the Company shall take all action necessary to at all times have
authorized, and reserved for the purpose of issuance, no less than 130% of the
sum of the number of shares of Common Stock issuable (i) upon conversion of the
Notes, and (ii) upon exercise of the Warrants then outstanding (without taking
into account any limitations on the conversion of the Notes or exercise of the
Warrants set forth in the Notes and Warrants, respectively).

              (n) CONDUCT OF BUSINESS. The business of the Company and its
Subsidiaries shall not be conducted in violation of any applicable law,
ordinance or regulation of any governmental entity, except where such violations
would not result, either individually or in the aggregate, in a Material Adverse
Effect.

              (o) ADDITIONAL ISSUANCES OF SECURITIES.

                   (i) For purposes of this Section 4(o), the following

                        (1) "CONVERTIBLE SECURITIES" means any stock or
         securities (other than Options) convertible into or exercisable or
         exchangeable for shares of Common Stock.

                        (2) "OPTIONS" means any rights, warrants or options to
         subscribe for or purchase shares of Common Stock or Convertible
         Securities.

                        (3) "COMMON STOCK EQUIVALENTS" means, collectively,
         Options and Convertible Securities.

                   (ii) From the date hereof until the date that is twelve (12)
months from the Closing Date (the "TRIGGER DATE"), the Company will not, (i)
directly or indirectly, offer, sell, grant any option to purchase, or otherwise
dispose of (or announce any offer, sale, grant or any option to purchase or
other disposition of) any of its or its Subsidiaries' debt, equity or equity
equivalent securities, including without limitation any debt, preferred stock or
other instrument or security that is, at any time during its life and under any
circumstances, convertible into or exchangeable or exercisable for shares of
Common Stock or Common Stock Equivalents (any such offer, sale, grant,
disposition or announcement being referred to as a "SUBSEQUENT PLACEMENT"),
other than to one or more of the Buyers provided the Company provides each of
the Buyers a right to participate in such Subsequent Placement pro rata based on
the aggregate principal amount of Notes purchased hereunder and does not give
any other Person the right to participate in such Subsequent Placement or (ii)
be party to any solicitations, negotiations or discussions with regard to the
foregoing.

                   (iii) Until the date that is two (2) years from the Closing
Date, the Company will not, directly or indirectly, effect any Subsequent
Placement unless the Company shall have first complied with this Section
4(o)(iii).

                        (1) The Company shall deliver to each Buyer written
         notice (the "OFFER NOTICE") of any proposed or intended issuance or
         sale or exchange (the "OFFER") of the securities being offered (the
         "OFFERED SECURITIES") in a Subsequent Placement, which Offer Notice
         shall (w) identify and describe the Offered Securities, (x) describe
         the price and other terms upon which they are to be issued, sold or
         exchanged, and the number or amount of the Offered Securities to be
         issued, sold or exchanged, (y) identify the persons or entities (if
         known) to which or with which the Offered Securities are to be offered,
         issued, sold or exchanged and (z) offer to issue and sell to or
         exchange with such Buyers all of the Offered Securities, allocated
         among such Buyers (a) based on such Buyer's pro rata portion of the
         aggregate principal amount of Notes purchased hereunder (the "BASIC
         AMOUNT"), and (b) with respect to each Buyer that elects to purchase
         its Basic Amount, any additional portion of the Offered Securities
         attributable to the Basic Amounts of other Buyers as such Buyer shall
         indicate it will purchase or acquire should the other Buyers subscribe
         for less than their Basic Amounts (the "UNDERSUBSCRIPTION AMOUNT").

                                      -21-

<PAGE>

                        (2) To accept an Offer, in whole or in part, such Buyer
         must deliver a written notice to the Company prior to the end of the
         tenth (10th) Business Day after such Buyer's receipt of the Offer
         Notice (the "OFFER PERIOD"), setting forth the portion of such Buyer's
         Basic Amount that such Buyer elects to purchase and, if such Buyer
         shall elect to purchase all of its Basic Amount, the Undersubscription
         Amount, if any, that such Buyer elects to purchase (in either case, the
         "NOTICE OF Acceptance"). If the Basic Amounts subscribed for by all
         Buyers are less than the total of all of the Basic Amounts, then each
         Buyer who has set forth an Undersubscription Amount in its Notice of
         Acceptance shall be entitled to purchase, in addition to the Basic
         Amounts subscribed for, the Undersubscription Amount it has subscribed
         for; PROVIDED, HOWEVER, that if the Undersubscription Amounts
         subscribed for exceed the difference between the total of all the Basic
         Amounts and the Basic Amounts subscribed for (the "AVAILABLE
         UNDERSUBSCRIPTION AMOUNT"), each Buyer who has subscribed for any
         Undersubscription Amount shall be entitled to purchase only that
         portion of the Available Undersubscription Amount as the Basic Amount
         of such Buyer bears to the total Basic Amounts of all Buyers that have
         subscribed for Undersubscription Amounts, subject to rounding by the
         Company to the extent it deems reasonably necessary.

                        (3) The Company shall have ten (10) Business Days from
         the expiration of the Offer Period above to offer, issue, sell or
         exchange all or any part of such Offered Securities as to which a
         Notice of Acceptance has not been given by the Buyers (the "REFUSED
         SECURITIES"), but only to the offerees described in the Offer Notice
         (if so described therein) and only upon terms and conditions
         (including, without limitation, unit prices and interest rates) that
         are not more favorable to the acquiring person or persons or less
         favorable to the Company than those set forth in the Offer Notice.

                        (4) In the event the Company shall propose to sell less
         than all the Refused Securities (any such sale to be in the manner and
         on the terms specified in Section 4(o)(iii)(3) above), then each Buyer
         may, at its sole option and in its sole discretion, reduce the number
         or amount of the Offered Securities specified in its Notice of
         Acceptance to an amount that shall be not less than the number or
         amount of the Offered Securities that such Buyer elected to purchase
         pursuant to Section 4(o)(iii)(2) above multiplied by a fraction, (i)
         the numerator of which shall be the number or amount of Offered
         Securities the Company actually proposes to issue, sell or exchange
         (including Offered Securities to be issued or sold to Buyers pursuant
         to Section 4(o)(iii)(3) above prior to such reduction) and (ii) the
         denominator of which shall be the original amount of the Offered
         Securities. In the event that any Buyer so elects to reduce the number
         or amount of Offered Securities specified in its Notice of Acceptance,
         the Company may not issue, sell or exchange more than the reduced
         number or amount of the Offered Securities unless and until such
         securities have again been offered to the Buyers in accordance with
         Section 4(o)(iii)(1) above.

<PAGE>

                        (5) Upon the closing of the issuance, sale or exchange
         of all or less than all of the Refused Securities, the Buyers shall
         acquire from the Company, and the Company shall issue to the Buyers,
         the number or amount of Offered Securities specified in the Notices of
         Acceptance, as reduced pursuant to Section 4(o)(iii)(3) above if the
         Buyers have so elected, upon the terms and conditions specified in the
         Offer. The purchase by the Buyers of any Offered Securities is subject
         in all cases to the preparation, execution and delivery by the Company
         and the Buyers of a purchase agreement relating to such Offered
         Securities reasonably satisfactory in form and substance to the Buyers
         and their respective counsel.

                        (6) Any Offered Securities not acquired by the Buyers or
         other persons in accordance with Section 4(o)(iii)(3) above may not be
         issued, sold or exchanged until they are again offered to the Buyers
         under the procedures specified in this Agreement.

                   (iv) The restrictions contained in subsections (ii) and (iii)
of this Section 4(o) shall not apply in connection with the issuance of any
Excluded Securities (as defined in the Notes).

              (p) ADDITIONAL REGISTRATION STATEMENTS. Except as permitted in the
Registration Rights Agreement, until the Trigger Date, the Company will not file
a registration statement (other than on Form S-8) under the 1933 Act relating to
securities that are not the Securities or were not issued to any Buyer or
Placement Agent pursuant to this Agreement, the Securities Purchase Agreement
dated as of July 30, 2007, as amended by the Amended and Restated Amendment and
Exchange Agreements dated as of January 22, 2007 (as amended, the "EXISTING
PURCHASE AGREEMENT"), or agreements related hereto or thereto, without the prior
written consent of the Buyers. Notwithstanding anything to the contrary in this
Agreement or the Transaction Documents, the Company may file such supplements,
amendments or other filings as may be deemed reasonably necessary or appropriate
by the Company to maintain the effectiveness of its outstanding registration
statements on Form SB-2.

              (q) COLLATERAL AGENT.

                   (i) Each Buyer hereby (a) appoints Castlerigg Master
Investments Ltd. as the collateral agent hereunder and under the other Security
Documents (in such capacity, the "COLLATERAL AGENT"), and (b) authorizes the
Collateral Agent (and its officers, directors, employees and agents) to take
such action on such Buyer's behalf in accordance with the terms hereof and
thereof. The Collateral Agent shall not have, by reason hereof or any of the
other Security Documents, a fiduciary relationship in respect of any Buyer.
Neither the Collateral Agent nor any of its officers, directors, employees and
agents shall have any liability to any Buyer for any action taken or omitted to
be taken in connection hereof or any other Security Document except to the
extent caused by its own gross negligence or willful misconduct, and each Buyer
agrees to defend, protect, indemnify and hold harmless the Collateral Agent and
all of its officers, directors, employees and agents (collectively, the
"INDEMNITEES") from and against any losses, damages, liabilities, obligations,
penalties, actions, judgments, suits, fees, costs and expenses (including,
without limitation, reasonable attorneys' fees, costs and expenses) incurred by
such Indemnitee ("INDEMNITY COSTS"), arising from or in connection with the
performance by such Indemnitee of the duties and obligations of Collateral Agent

                                      -23-

<PAGE>

pursuant hereto or any of the Security Documents; provided, that, (i) the
liability of any Buyer pursuant to this Section 4(q) shall be several and not
joint with any other Buyer, and shall not exceed in the aggregate its pro rata
percentage of such Indemnity Costs (based on the percentage of Securities that
such Buyer shall acquire at the Closing as a percentage of all Securities sold
at the Closing) and (ii) no Buyer shall be obligated under this Section 4 (q)
for any indirect or consequential Indemnity Costs.

                   (ii) The Collateral Agent shall be entitled to rely upon any
written notices, statements, certificates, orders or other documents or any
telephone message believed by it reasonably and in good faith to be genuine and
correct and to have been signed, sent or made by the proper Person, and with
respect to all matters pertaining to this Agreement or any of the other
Transaction Documents and its duties hereunder or thereunder, upon advice of
counsel selected by it.

                   (iii) The Collateral Agent may resign from the performance of
all its functions and duties hereunder and under the Notes and the Security
Documents at any time by giving at least ten (10) Business Days prior written
notice to the Company and each holder of the Notes. Such resignation shall take
effect upon the acceptance by a successor Collateral Agent of appointment as
provided below. Upon any such notice of resignation, the holders of a majority
of the outstanding principal under the Notes shall appoint a successor
Collateral Agent. Upon the acceptance of the appointment as Collateral Agent,
such successor Collateral Agent shall succeed to and become vested with all the
rights, powers, privileges and duties of the retiring Collateral Agent, and the
retiring Collateral Agent shall be discharged from its duties and obligations
under this Agreement, the Notes and the other Security Documents. After any
Collateral Agent's resignation hereunder, the provisions of this Section 4(q)
shall inure to its benefit. If a successor Collateral Agent shall not have been
so appointed within said ten (10) Business Day period, the retiring Collateral
Agent shall then appoint a successor Collateral Agent who shall serve until such
time, if any, as the holders of a majority of the outstanding principal under
the Notes appoint a successor Collateral Agent as provided above.

              (r) STOCKHOLDER APPROVAL.

                   (i) If the Common Stock is listed on an Eligible Market (as
defined in the Registration Rights Agreement) other than the Principal Market
(the "NEW PRINCIPAL MARKET") and the issuance of the Conversion Shares and
Warrant Shares as contemplated under the Transaction Documents would exceed that
number of shares of Common Stock which the Company may issue without breaching
the Company's obligations under the rules or regulations of the New Principal
Market, then the Company shall obtain the approval of its stockholders as
required by the applicable rules of the New Principal Market for issuances of
the Conversion Shares and Warrant Shares in excess of such amount. At such time,
the Company shall provide each stockholder entitled to vote at a special or
annual meeting of stockholders of the Company (the "STOCKHOLDER MEETING"), which
shall be promptly called and held not later than 75 days after the earlier of
(i) the New Principal Market indication of and (ii) the Company becoming aware
of, any limitation imposed by the New Principal Market on the issuance of
Conversion Shares or Warrant Shares (the "STOCKHOLDER MEETING DEADLINE"), a
proxy statement, substantially in the form which has been previously reviewed by

                                      -24-

<PAGE>

the Buyers and Schulte Roth & Zabel LLP, at the expense of the Company,
soliciting each such stockholder's affirmative vote at the Stockholder Meeting
for approval of resolutions providing for the Company's issuance of all of the
Securities as described in the Transaction Documents in accordance with
applicable law and the rules and regulations of the New Principal Market and
such affirmative approval being referred to herein as the "STOCKHOLDER
APPROVAL"), and the Company shall use its reasonable best efforts to (i) solicit
its stockholders' approval of such resolutions and to (ii) cause the Board of
Directors of the Company to recommend to the stockholders that they approve such
resolutions. The Company shall be obligated to use its reasonable best efforts
to obtain the Stockholder Approval by the Stockholder Meeting Deadline. If,
despite the Company's reasonable best efforts the Stockholder Approval is not
obtained on or prior to the Stockholder Meeting Deadline, the Company shall
cause an additional Stockholder Meeting to be held every six (6) months
thereafter until such Stockholder Approval is obtained or the Notes and the
Warrants are no longer outstanding.

              (s) TRADING RESTRICTIONS. Neither the Buyer, nor any affiliate of
the Buyer that is controlled by the Buyer or is otherwise aware of this
restriction, may purchase, sell or enter into any put option, short position or
similar arrangement with respect to securities of the Company that violates
Current Securities Laws (as defined below) or otherwise trade in the securities
of the Company in violation of applicable Current Securities Laws. In addition,
during each Company Conversion Measuring Period (as defined in the Notes)
neither the Buyer, nor any affiliate of the Buyer that is controlled by the
Buyer or is otherwise aware of this restriction, may engage in a Restricted
Activity other than the sale of shares of Common Stock received upon a Company
Conversion, a Mandatory Conversion or an Optional Conversion (as such terms are
defined in the Notes), upon a conversion, amortization or redemption of Notes
pursuant to terms contained therein, upon exercise of any Warrants, or the
transfer of any Notes or Warrants as permitted by their terms. "RESTRICTED
ACTIVITY" means, (a) any Acquisition or Disposition, in open market transactions
of (i) any shares of Common Stock or (ii) any securities convertible into or
exchangeable for or derivative of shares of Common Stock and (b) any other
action taken intentionally for the purpose of manipulating the price of shares
of Common Stock. "ACQUISITION" means any direct or indirect voluntary
acquisition or purchase (other than by merger, consolidation, combination,
recapitalization or other reorganization, or by operation of law). "DISPOSITION"
means any direct or indirect voluntary sale, or monetization, including through
a subsidiary or by means of an equity offering by any such subsidiary, but shall
not include, any of the actions contemplated by Section 4(h) or any disposition
thereunder. "CURRENT SECURITIES LAWS" means the rules and regulations, as then
in effect, of the 1933 Act and the 1934 Act, in each case as are set forth in
currently disseminated interpretations by the SEC in writing, through rules,
regulations, releases, no-action letters or published telephone interpretations.

              (t) SECURITY. Within fifteen (15) days of the Closing Date, the
Company shall, and shall cause its Subsidiaries to, secure the Company's
liabilities and obligations under the Notes by granting to the Buyers a first
priority perfected security interest in all of the assets and properties of the
Company and its Subsidiaries, including (without limitation) the capital stock
and assets and properties of each of the Company's Subsidiaries, evidenced by a
Security Agreement and a Pledge Agreement in form and substance reasonably
satisfactory to the Buyers and the Company; PROVIDED, HOWEVER, that it is

                                      -25-

<PAGE>

understood that all of the assets and properties of the Company and its
Subsidiaries, including (without limitation) the capital stock and assets and
properties of each of the Company's Subsidiaries shall be subject to the first
priority security interest evidenced therein. Within fifteen (15) days of the
Closing Date, the Company shall cause each of its Subsidiaries to enter into a
Guarantee in form and substance reasonably satisfactory to the Buyers and the
Company, guaranteeing the Company's liabilities and obligations under the Notes.

              (u) CLOSING DOCUMENTS. On or prior to fourteen (14) calendar days
after the Closing Date, the Company agrees to deliver, or cause to be delivered,
to each Buyer and Schulte Roth & Zabel LLP executed copies of the Transaction
Documents, Securities and any other document required to be delivered by the
Company to any party pursuant to Section 7 hereof.

              (v) WAIVER OF CONFLICT WITH EXISTING PURCHASE AGREEMENT. To the
extent the Transaction Documents or any of the transactions contemplated thereby
result in a breach of, conflict with, or otherwise violate the Existing Purchase
Agreement or the notes, warrants or other agreements related thereto, each Buyer
hereby forever waives any such breach, conflict or violation.

         5. REGISTER; TRANSFER AGENT INSTRUCTIONS.

              (a) REGISTER. The Company shall maintain at its principal
executive offices (or such other office or agency of the Company as it may
designate by notice to each holder of Securities), a register for the Notes and
the Warrants in which the Company shall record the name and address of the
Person in whose name the Notes and the Warrants have been issued (including the
name and address of each transferee), the principal amount of Notes held by such
Person, the number of Conversion Shares issuable upon conversion of the Notes
and Warrant Shares issuable upon exercise of the Warrants held by such Person.
The Company shall keep the register open and available at all times during
business hours for inspection of any Buyer or its legal representatives.

              (b) TRANSFER AGENT INSTRUCTIONS. The Company shall issue
irrevocable instructions to its transfer agent, and any subsequent transfer
agent, to issue certificates or credit shares to the applicable balance accounts
at The Depository Trust Company ("DTC"), registered in the name of each Buyer or
its respective nominee(s), for the Conversion Shares and the Warrant Shares
issued at the Closing or upon conversion of the Notes or exercise of the
Warrants in such amounts as specified from time to time by each Buyer to the
Company upon conversion of the Notes or exercise of the Warrants in the form of
EXHIBIT F attached hereto (the "IRREVOCABLE TRANSFER AGENT INSTRUCTIONS"). The
Company warrants that no instruction other than the Irrevocable Transfer Agent
Instructions referred to in this Section 5(b), and stop transfer instructions to
give effect to Section 2(g) hereof, will be given by the Company to its transfer
agent, and that the Securities shall otherwise be freely transferable on the
books and records of the Company as and to the extent permitted by applicable
federal and state securities laws and as provided in this Agreement and the
other Transaction Documents. If a Buyer effects a sale, assignment or transfer
of the Securities in accordance with Section 2(f), the Company shall permit the
transfer and shall promptly instruct its transfer agent to issue one or more
certificates or credit shares to the applicable balance accounts at DTC in such
name and in such denominations as specified by such Buyer to effect such sale,
transfer or assignment. In the event that such sale, assignment or transfer
involves Conversion Shares or Warrant Shares sold, assigned or transferred

                                      -26-

<PAGE>

pursuant to an effective registration statement or pursuant to Rule 144, the
transfer agent shall issue such Securities to the Buyer, assignee or transferee,
as the case may be, without any restrictive legend. The Company acknowledges
that a breach by it of its obligations hereunder will cause irreparable harm to
a Buyer. Accordingly, the Company acknowledges that the remedy at law for a
breach of its obligations under this Section 5(b) will be inadequate and agrees,
in the event of a breach or threatened breach by the Company of the provisions
of this Section 5(b), that a Buyer shall be entitled, in addition to all other
available remedies, to an order and/or injunction restraining any breach and
requiring immediate issuance and transfer, without the necessity of showing
economic loss and without any bond or other security being required.

         6. CONDITIONS TO THE COMPANY'S OBLIGATION TO SELL.

              CLOSING DATE. The obligation of the Company hereunder to issue and
sell the Notes and the related Warrants to each Buyer at the Closing is subject

warranties that speak as of a specific date), and such Buyer shall have
performed, satisfied and complied in all material respects with the covenants,
agreements and conditions required by this Agreement to be performed, satisfied
or complied with by such Buyer at or prior to the Closing Date.

                   (vii) The representations and warranties of the Company shall

due to the Company's or such Buyer's failure to satisfy the conditions set forth

PROVIDED, HOWEVER, that if this Agreement is terminated pursuant to this Section

         9. MISCELLANEOUS.

              (a) GOVERNING LAW; JURISDICTION; JURY TRIAL. All questions
concerning the construction, validity, enforcement and interpretation of this
Agreement shall be governed by the internal laws of the State of New York,
without giving effect to any choice of law or conflict of law provision or rule
(whether of the State of New York or any other jurisdictions) that would cause
the application of the laws of any jurisdictions other than the State of New
York. Each party hereby irrevocably submits to the exclusive jurisdiction of the
state and federal courts sitting in The City of New York, Borough of Manhattan,
for the adjudication of any dispute hereunder or in connection herewith or with
any transaction contemplated hereby or discussed herein, and hereby irrevocably
waives, and agrees not to assert in any suit, action or proceeding, any claim
that it is not personally subject to the jurisdiction of any such court, that
such suit, action or proceeding is brought in an inconvenient forum or that the
venue of such suit, action or proceeding is improper. Each party hereby

WAIVES ANY RIGHT IT MAY HAVE, AND AGREES NOT TO REQUEST, A JURY TRIAL FOR THE
ADJUDICATION OF ANY DISPUTE HEREUNDER OR IN CONNECTION WITH OR ARISING OUT OF

              (b) COUNTERPARTS. This Agreement may be executed in two or more
identical counterparts, all of which shall be considered one and the same
agreement and shall become effective when counterparts have been signed by each
party and delivered to the other party; provided that a facsimile signature
shall be considered due execution and shall be binding upon the signatory
thereto with the same force and effect as if the signature were an original, not
a facsimile signature.

              (c) HEADINGS. The headings of this Agreement are for convenience
of reference and shall not form part of, or affect the interpretation of, this
Agreement.

              (d) SEVERABILITY. If any provision of this Agreement shall be
invalid or unenforceable in any jurisdiction, such invalidity or
unenforceability shall not affect the validity or enforceability of the
remainder of this Agreement in that jurisdiction or the validity or
enforceability of any provision of this Agreement in any other jurisdiction.

              (e) ENTIRE AGREEMENT; AMENDMENTS. This Agreement and the other
Transaction Documents supersede all other prior oral or written agreements
between the Buyers, the Company, their affiliates and Persons acting on their
behalf with respect to the matters discussed herein, and this Agreement, the
other Transaction Documents and the instruments referenced herein and therein
contain the entire understanding of the parties with respect to the matters
covered herein and therein and, except as specifically set forth herein or
therein, neither the Company nor any Buyer makes any representation, warranty,
covenant or undertaking with respect to such matters. No provision of this
Agreement may be amended other than by an instrument in writing signed by the
Company and the holders of at least a majority of the aggregate number of
Registrable Securities issued and issuable hereunder, and any amendment to this
Agreement made in conformity with the provisions of this Section 9(e) shall be
binding on all Buyers and holders of Securities, as applicable. No provision
hereof may be waived other than by an instrument in writing signed by the party
against whom enforcement is sought. No such amendment shall be effective to the
extent that it applies to less than all of the holders of the applicable
Securities then outstanding. No consideration shall be offered or paid to any
Person to amend or consent to a waiver or modification of any provision of any
of the Transaction Documents unless the same consideration also is offered to
all of the parties to the Transaction Documents, holders of Notes or holders of
the Warrants, as the case may be. The Company has not, directly or indirectly,
made any agreements with any Buyers relating to the terms or conditions of the
transactions contemplated by the Transaction Documents except as set forth in
the Transaction Documents. Without limiting the foregoing, the Company confirms
that, except as set forth in this Agreement, no Buyer has made any commitment or
promise or has any other obligation to provide any financing to the Company or
otherwise.

              (g) SUCCESSORS AND ASSIGNS. This Agreement shall be binding upon
and inure to the benefit of the parties and their respective successors and
assigns, including any purchasers of the Notes or the Warrants. The Company
shall not assign this Agreement or any rights or obligations hereunder without
the prior written consent of the holders of at least a majority of the aggregate
number of Registrable Securities issued and issuable hereunder, including by way
of a Fundamental Transaction (unless the Company is in compliance with the
applicable provisions governing Fundamental Transactions set forth in the Notes
and the Warrants). A Buyer may assign some or all of its rights hereunder
without the consent of the Company, in which event such assignee shall be deemed
to be a Buyer hereunder with respect to such assigned rights.

              (h) NO THIRD PARTY BENEFICIARIES. 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.

              (i) SURVIVAL. Unless this Agreement is terminated under Section 8,
the representations and warranties of the Company and the Buyers contained in
Sections 2 and 3 and the agreements and covenants set forth in Sections 4, 5 and
9 shall survive the Closing. Each Buyer shall be responsible only for its own
representations, warranties, agreements and covenants hereunder.

              (j) FURTHER ASSURANCES. Each party shall do and perform, or cause
to be done and performed, all such further acts and things, and shall execute
and deliver all such other agreements, certificates, instruments and documents,
as any other party may reasonably request in order to carry out the intent and
accomplish the purposes of this Agreement and the consummation of the
transactions contemplated hereby.

              (k) INDEMNIFICATION. In consideration of each Buyer's execution
and delivery of the Transaction Documents and acquiring the Securities
thereunder and in addition to all of the Company's other obligations under the
Transaction Documents, the Company shall defend, protect, indemnify and hold
harmless each Buyer and each other holder of the Securities and all of their
stockholders, partners, members, officers, directors, employees and direct or
indirect investors and any of the foregoing Persons' agents or other
representatives (including, without limitation, those retained in connection
with the transactions contemplated by this Agreement) (collectively, the
"INDEMNITEES") from and against any and all actions, causes of action, suits,
claims, losses, costs, penalties, fees, liabilities and damages, and expenses in
connection therewith (irrespective of whether any such Indemnitee is a party to
the action for which indemnification hereunder is sought), and including
reasonable attorneys' fees and disbursements (the "INDEMNIFIED LIABILITIES"),
incurred by any Indemnitee as a result of, or arising out of, or relating to (a)
any misrepresentation or breach of any representation or warranty made by the
Company in the Transaction Documents or any other certificate, instrument or
document contemplated hereby or thereby, (b) any breach of any covenant,
agreement or obligation of the Company contained in the Transaction Documents or
any other certificate, instrument or document contemplated hereby or thereby or
(c) any cause of action, suit or claim brought or made against such Indemnitee
by a third party (including for these purposes a derivative action brought on
behalf of the Company) and arising out of or resulting from (i) the execution,
delivery, performance or enforcement of the Transaction Documents or any other
certificate, instrument or document contemplated hereby or thereby, (ii) any
transaction financed or to be financed in whole or in part, directly or

                                      -32-

<PAGE>

indirectly, with the proceeds of the issuance of the Securities, (iii) any
disclosure made by such Buyer pursuant to Section 4(i), or (iv) the status of
such Buyer or holder of the Securities as an investor in the Company pursuant to
the transactions contemplated by the Transaction Documents. To the extent that
the foregoing undertaking by the Company may be unenforceable for any reason,
the Company shall make the maximum contribution to the payment and satisfaction
of each of the Indemnified Liabilities which is permissible under applicable
law. Except as otherwise set forth herein, the mechanics and procedures with
respect to the rights and obligations under this Section 9(k) shall be the same
as those set forth in Section 6 of the Registration Rights Agreement. This
Section 9(k) shall not apply to any Indemnified Liabilities to the extent that
such Indemnified Liabilities result from or relate to the willful misconduct or
gross negligence of any Buyer.

              (l) NO STRICT CONSTRUCTION. The language used in this Agreement
will be deemed to be the language chosen by the parties to express their mutual
intent, and no rules of strict construction will be applied against any party.

              (m) REMEDIES. Each Buyer and each holder of the Securities shall
have all rights and remedies set forth in the Transaction Documents and all
rights and remedies which such holders have been granted at any time under any
other agreement or contract and all of the rights which such holders have under
any law. Any Person having any rights under any provision of this Agreement
shall be entitled to enforce such rights specifically (without posting a bond or
other security), to recover damages by reason of any breach of any provision of
this Agreement and to exercise all other rights granted by law. Furthermore, the
Company recognizes that in the event that it fails to perform, observe, or
discharge any or all of its obligations under the Transaction Documents, any
remedy at law may prove to be inadequate relief to the Buyers. The Company
therefore agrees that the Buyers shall be entitled to seek temporary and
permanent injunctive relief in any such case without the necessity of proving
actual damages and without posting a bond or other security.

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

              (o) PAYMENT SET ASIDE. To the extent that the Company makes a
payment or payments to the Buyers hereunder or pursuant to any of the other
Transaction Documents or the Buyers enforce or exercise their rights hereunder
or thereunder, and such payment or payments or the proceeds of such enforcement
or exercise or any part thereof are subsequently invalidated, declared to be
fraudulent or preferential, set aside, recovered from, disgorged by or are
required to be refunded, repaid or otherwise restored to the Company, a trustee,
receiver or any other Person under any law (including, without limitation, any
bankruptcy law, foreign, state or federal law, common law or equitable cause of
action), then to the extent of any such restoration the obligation or part
thereof originally intended to be satisfied shall be revived and continued in
full force and effect as if such payment had not been made or such enforcement
or setoff had not occurred.

              (p) INDEPENDENT NATURE OF BUYERS' OBLIGATIONS AND RIGHTS. The
obligations of each Buyer under any Transaction Document are several and not
joint with the obligations of any other Buyer, and no Buyer shall be responsible
in any way for the performance of the obligations of any other Buyer under any
Transaction Document. Nothing contained herein or in any other Transaction
Document, and no action taken by any Buyer pursuant hereto or thereto, shall be
deemed to constitute the Buyers as a partnership, an association, a joint
venture or any other kind of entity, or create a presumption that the Buyers are
in any way acting in concert or as a group with respect to such obligations or
the transactions contemplated by the Transaction Documents and the Company
acknowledges that, to the Company's knowledge, the Buyers are not acting in
concert or as a group with respect to such obligations or the transactions
contemplated by the Transaction Documents. Each Buyer confirms that it has
independently participated in the negotiation of the transaction contemplated
hereby with the advice of its own counsel and advisors. Each Buyer shall be
entitled to independently protect and enforce its rights, including, without
limitation, the rights arising out of this Agreement or out of any other
Transaction Documents, and it shall not be necessary for any other Buyer to be
joined as an additional party in any proceeding for such purpose.
