     2. BUYER'S REPRESENTATIONS AND WARRANTIES.

          Each Buyer represents and warrants with respect to only itself that:

          (a) No Public Sale or Distribution. Such Buyer is acquiring the
Debentures and the Warrants for its own account and not with a view towards, or
for resale in connection with, the public sale or distribution thereof in a
manner that would violate the 1933 Act, 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 to distribute any of the Securities.

          (b) 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 Companies are 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) 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.

          (e) Transfer or Resale. Such Buyer understands that except as provided

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 Companies 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 Buyer
provides the Companies with reasonable assurance that such Securities can be
sold, assigned or transferred pursuant to Rule 144 or Rule 144A promulgated
under the 1933 Act (or, in each case, a successor rule thereto); provided,
however, that 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 Companies with any notice thereof or
otherwise make any delivery to the Companies pursuant to this Agreement or any
other Transaction Document (as defined in Section 3(b)), including, without

instruments representing the Debentures and, until removed in accordance with
the Registration Rights Agreement, the certificates representing the Warrants
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):

     THE SECURITIES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN
     REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED, OR APPLICABLE

          As an inducement to the Buyers to enter into this Agreement and to
consummate the transactions contemplated hereby, each of the Companies jointly
and severally represents and warrants to each of the Buyers that each and all of
the following representations and warranties (as modified by the disclosure
schedules delivered to the Buyers contemporaneously with the execution and
delivery of this Agreement (the "Schedules")) are true and correct as of the
date of this Agreement. The Schedules shall be arranged by the Companies in
paragraphs corresponding to the sections and subsections contained in this
Section 3.

                                       4
<PAGE>

          (a) Organization and Qualification. Parent and its "Subsidiaries"
(which for purposes of this Agreement means any entity in which Parent, directly
or indirectly, owns capital stock or holds an equity or similar interest,
including the Companies) 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 Parent 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,
operations, results of operations, condition (financial or otherwise) or
prospects of Parent and its Subsidiaries, taken as whole, or on the transactions
contemplated hereby and by the other Transaction Documents, or on the authority
or ability of each of the Companies to perform its obligations under the
Transaction Documents. Parent has no Subsidiaries, except as set forth on
Schedule 3(a).

          (b) Authorization; Enforcement; Validity. Each of the Companies has
the requisite power and authority to enter into and perform its obligations
under this Agreement, the Debentures, the Warrants, the Registration Rights
Agreement, the Irrevocable Transfer Agent Instructions (as defined in Section
5(b)), the Security Documents, 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 Companies have been duly authorized
by each of the Companies' respective Board of Directors and the consummation by
the Companies of the transactions contemplated hereby and thereby, including,
without limitation, the issuance of the Debentures by the Companies and the
issuance of the Warrants by Parent, have been duly authorized by the Companies'
Boards of Directors and Parent's Board of Directors, as applicable, and (other
than the filing with the SEC of a Form D and one or more Registration Statements
in accordance with the requirements of the Registration Rights Agreement and
other than filings with "Blue Sky" authorities as required therein) no further
filing, consent, or authorization is required by any 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 each of
the Companies, and constitute the legal, valid and binding obligations of each
of the Companies, enforceable against the Companies 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 Debentures and the Warrants are duly
authorized and, upon issuance in accordance with the terms hereof, shall be
validly issued and free from all taxes, liens and charges with respect to the
issue thereof. As of the Closing Date, Parent shall have duly authorized and
reserved for issuance a number of shares of Common Stock which equals 110% of

                                       5
<PAGE>

the number of Warrant Shares. Parent shall, so long as any of the Warrants are
outstanding, take all action necessary to reserve and keep available out of its
authorized and unissued Common Stock, solely for the purpose of effecting the
exercise of the Warrants, at least 110% of the number of shares of Common Stock
issuable upon exercise of the Warrants. Upon exercise in accordance with the
Warrants, the Warrant Shares will be validly issued, fully paid and
nonassessable and free from all 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. Assuming the truth and accuracy of, and each Buyer's
compliance with, the representations, warranties, agreements, acknowledgments
and understandings of each Buyer set forth in this Agreement (including but not
limited to Section 2(c)), the issuance by the Companies of the Debentures and
the issuance by Parent of the Warrants is exempt from registration under the
1933 Act.

          (d) No Conflicts. The execution, delivery and performance of the
Transaction Documents by the Companies and the consummation by the Companies of
the transactions contemplated hereby and thereby (including, without limitation,
the issuance of the Debentures and the Warrants) will not (i) result in a
violation of each Company's Articles of Incorporation or each Company's Bylaws
(each as defined in Section 3(r)) or the governing documents of any of Parent's
Subsidiaries or the terms of any capital stock of Parent or any of its
Subsidiaries; (ii) conflict with, or constitute a breach or default (or an event
which with notice or lapse of time or both, would become a breach or default)
under, or give to others any rights of termination, amendment, acceleration or
cancellation of, any agreement, indenture or instrument to which Parent or any
of its Subsidiaries is a party, except for conflicts, breaches, defaults or
rights under the "right of first refusal" provisions of warrants disclosed on
Schedule 3(r) which would not have a Material Adverse Effect; or (iii) result in
a violation of any law, rule, regulation, order, judgment or decree (including
federal and state securities laws and the rules and regulations of the OTC
Bulletin Board (the "Principal Market")) applicable to Parent or any of its
Subsidiaries or by which any property or asset of Parent or any of its
Subsidiaries is bound or affected.

          (e) Consents. No Company 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 (other than (v) the filing with the SEC of a
Form D or one or more Registration Statements in accordance with the
requirements of the Registration Rights Agreement, (w) filings with "Blue Sky"
authorities as required thereby, (x) filings required by the Security Documents,
(y) consents under the "right of first refusal" provisions of warrants disclosed
on Schedule 3(r) which would not have a Material Adverse Effect, and (z) as set
forth on Schedule 3(e)). Except for (i) outstanding comments from the SEC with
respect to Parent's Form 10-K for the fiscal year ended December 31, 2006 and
Forms 10-Q for the quarters ended June 30, 2007 and September 30, 2007 to which
the Company is currently responding, (ii) the pending declaration of
effectiveness of a post-effective amendment to an existing registration
statement that will not be declared effective until the Company clears the
aforesaid SEC comments, and (iii) consents under the "right of first refusal"
provisions of warrants disclosed on Schedule 3(r) which would not have a
Material Adverse Effect, no consents, authorizations, orders, filings and

                                       6
<PAGE>

registrations which the Companies are required to obtain pursuant to the
preceding sentence have not been obtained or effected on or prior to the Closing
Date, and each Company is unaware of any facts or circumstances which might
prevent any of the Companies from obtaining or effecting any of the
registration, application or filings pursuant to the preceding sentence. Parent
is not in violation of the listing requirements of the OTC Bulletin Board (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. Each of
the Companies acknowledges and agrees that each Buyer is acting solely in the
capacity of an 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 any Company, (ii) an "affiliate" of any Company (as
defined in Rule 144) or (iii) to the knowledge of the Companies, 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")). Each of the Companies further acknowledges that no Buyer is acting as a
financial advisor or fiduciary of any 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. Each of the Companies further represents to each Buyer that each
Company's decisions to enter into the Transaction Documents have been based
solely on the independent evaluation by the Companies and their respective
representatives.

          (g) No General Solicitation; Placement Agent's Fees. None of the
Companies, nor any of their 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. Parent shall be responsible for the payment of any placement agent's
fees, financial advisory fees, or brokers' commissions (other than for Persons
engaged by the Buyers or their investment advisors) relating to or arising out
of the transactions contemplated hereby. Parent 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. No Company has engaged any placement agent or other agent in connection
with the sale of the Securities.

          (h) No Integrated Offering. None of the Companies, any of their
affiliates, or 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 any of the
Securities under the 1933 Act or cause this offering of the Securities to be
integrated with prior offerings by any of the Companies 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 Parent or any other Company
are listed or designated. None of the Companies, their affiliates or any Person
acting on their behalf will take any action or steps referred to in the
preceding sentence that would require registration of any of the Securities
under the 1933 Act or cause the offering of the Securities to be integrated with
other offerings. Except for the pending post-effective amendment to an existing
registration statement, none of the Companies has a registration statement
pending before the SEC or currently under the SEC's review.

                                       7
<PAGE>

          (i) U.S. Real Property Holding Corporation. None of the Companies is,
nor has it 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
Companies will so certify upon the request of any Buyer.

          (j) Application of Takeover Protections; Rights Agreement. Each of the
Companies and its respective board of directors has 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 each Company's 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, each Company's issuance of the
Debentures, Parent's issuance of the Warrants and any Buyer's ownership of the
Securities. Parent 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 Parent.

          (k) SEC Documents; Financial Statements. Parent has filed all reports,
schedules, forms, statements and other documents required to be filed by it with
the SEC pursuant to the reporting requirements of the 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"). As of
their respective dates, 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 Documents, and none of the SEC
Documents, at the time they were filed with the SEC, 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 Parent 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 Parent 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).

          (l) Absence of Certain Changes. Except as disclosed in Schedule 3(l)
or in Parent's Quarterly Report on Form 10-Q for the period ended September 30,
2007, since September 30, 2007, there has been no material adverse change and no
material adverse development in the business, assets, properties, operations,
condition (financial or otherwise), results of operations or prospects of Parent
or its Subsidiaries. Except as disclosed in Schedule 3(l), since September 30,
2007, Parent has not (i) declared or paid any dividends, (ii) sold any assets or
(iii) had capital expenditures, individually or in the aggregate, in excess of
$100,000. None of the Companies has taken any steps to seek protection pursuant
to any bankruptcy law nor does any of the Companies have any knowledge or reason

                                       8
<PAGE>

to believe that its creditors intend to initiate involuntary bankruptcy
proceedings or any actual knowledge of any fact which would reasonably lead a
creditor to do so. None of the Companies intends to incur debts beyond its
ability to pay such debts as they mature (taking into account the timing and
amounts of cash to be payable on or in respect of its debt). None of the
Companies has any knowledge of any facts or circumstances which lead it to
believe that it will file for reorganization or liquidation under the bankruptcy
or reorganization laws of any jurisdiction within one year from the Closing
Date. No Company is, as of the date hereof, and after giving effect to the
transactions contemplated hereby to occur at the Closing, will be Insolvent (as
defined below). For purposes of this Section 3(l), "Insolvent" means, with
respect to each Company (i) the present fair saleable value of such Company's
assets is less than the amount required to pay such Company's total Indebtedness
(as defined in Section 3(s)), as applicable, (ii) such Company is unable to pay
its debts and liabilities, subordinated, contingent or otherwise, as such debts
and liabilities become absolute and matured, (iii) such 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 Company 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 for the transaction contemplated by the Transaction Documents, no event,
liability, development or circumstance has occurred or exists, or is
contemplated to occur with respect to any of the Companies or their respective
business, properties, prospects, operations or financial condition, that would
be required to be disclosed by Parent under applicable securities laws on a
registration statement on Form S-1 filed with the SEC relating to an issuance
and sale by Parent of its Common Stock and which has not been publicly
announced.

          (n) Conduct of Business; Regulatory Permits. Except for the failure of
Parent to hold its 2007 annual meeting within the time prescribed by its
Articles of Incorporation and By-Laws as a consequence of outstanding comments
from the SEC, none of the Companies is in violation of any term of or in default
under its Articles of Incorporation or Bylaws or other governing documents. None
of the Companies is in violation of any judgment, decree or order or any
statute, ordinance, rule or regulation applicable to the Companies. Without
limiting the generality of the foregoing, Parent 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 that would reasonably lead to delisting
or suspension of the Common Stock by the Principal Market in the foreseeable
future. During the one (1) year period prior to the date hereof, (i) the Common
Stock has been designated for quotation on the Principal Market, (ii) trading in
the Common Stock has not been suspended by the SEC or the Principal Market and
(iii) Parent has received no communication, written or oral, from the SEC or the
Principal Market regarding the suspension or delisting of the Common Stock from
the Principal Market. Each of the Companies possesses all certificates,
authorizations and permits issued by the appropriate regulatory authorities
necessary to conduct their respective businesses, and none of the Companies has
received any notice of proceedings relating to the revocation or modification of
any such certificate, authorization or permit.

          (o) Foreign Corrupt Practices. None of the Companies, nor any
director, officer, agent, employee or other Person acting on behalf of any of

<PAGE>

addition, the term "Indebtedness" includes all Indebtedness of others secured by

Subsidiaries or any of Parent's or its Subsidiaries' officers or directors which

Documents or any of the transactions contemplated hereby or thereby or any
action taken or to be taken pursuant hereto or thereto.

          (u) Insurance. Each of the Companies is insured by insurers of
recognized financial responsibility against such losses and risks and in such
amounts as management of the Companies believes to be prudent and customary in
the businesses in which the Companies are engaged. None of the Companies has
been refused any insurance coverage sought or applied for and none of the
Companies 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. None of the Companies is a party to any
collective bargaining agreement or employs any member of a union. Each of the

the knowledge of the Companies, 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. Each of the Companies are in
compliance with all federal, state, local and foreign laws and regulations
respecting labor, employment and employment practices and benefits, terms and

real property and good and marketable title to all personal property owned by
them which is material to the business of such Company, in each case free and

and enforceable leases.

          (x) Intellectual Property Rights. Each of the Companies owns or
possesses 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

businesses as now conducted. No Company's Intellectual Property Rights have
expired or terminated, or are expected to expire or terminate, within three
years from the date of this Agreement. None of the Companies has any knowledge

others. There is no claim, action or proceeding being made or brought, or to the
knowledge of each of the Companies, being threatened, against any of the
Companies regarding its Intellectual Property Rights. Each of the Companies is
unaware of any facts or circumstances which might give rise to any of the
foregoing infringements or claims, actions or proceedings. Each of the Companies

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

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

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

no basis for any such claim.

system of internal accounting controls sufficient to provide reasonable

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)

existing assets and liabilities at reasonable intervals and appropriate action

and procedures (as such term is defined in Rule 13a-15 under the 1934 Act) that
are effective in ensuring that information required to be disclosed by Parent 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 Parent in the
reports that it files or submits under the 1934 Act is accumulated and
communicated to Parent'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. Except as disclosed by the
Company in filings with the SEC, during the twelve months prior to the date
hereof, none of the Companies have received any notice or correspondence from
any accountant relating to any potential material weakness in any part of the
system of internal accounting controls of any of the Companies.

arrangement, or other relationship between any of the Companies and an
unconsolidated or other off balance sheet entity that is required to be
disclosed by Parent in its 1934 Act filings and is not so disclosed or that
otherwise would be reasonably likely to have a Material Adverse Effect.

          (ee) Ranking of Debentures. No Indebtedness of any of the Companies

whether with respect to payment of redemptions, interest, damages or upon
liquidation or dissolution or otherwise.

          (ff) Transfer Taxes. On the Closing Date, all stock transfer or other

Companies, and all laws imposing such taxes will be or will have been complied

               (i) Neither any of the Companies, nor any officer, director or

to cause or to result in the stabilization or manipulation of the price of any
security of Parent to facilitate the sale or resale of any of the Securities,
(ii) sold, bid for, purchased, or paid any compensation for soliciting purchases
of, any of the Securities (except for customary placement fees payable in
connection with this transaction), or (iii) paid or agreed to pay to any Person

          (hh) Creation, Perfection, and Priority of Liens. The Security
Documents are effective to create in favor of the Buyers, for the benefit of the
Buyers, a legal, valid, binding, and enforceable security interest and Lien (as
defined below), and a first priority security interest and Lien with respect to
the Senior Debentures and a second priority interest and Lien with respect to
the Junior Debenture (to the extent that the Debentures obligates each Company

a legal, valid, binding, and enforceable security interest and Lien in such
Collateral may be created under applicable law, and the State of Registration

<PAGE>

          (ii) Disclosure. Each of the Companies confirms that neither it nor
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 which will continue to
constitute material, nonpublic information on the 90th day following the
Closing. Each of the Companies understands and confirms that each of the Buyers
will rely on the foregoing representations in effecting transactions in
securities of the Companies. All disclosure provided to the Buyers regarding
each of the Companies, its business and the transactions contemplated hereby,
including the Schedules to this Agreement, furnished by or on behalf of each
Company 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 Parent 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 Parent 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 Parent but which has not been so publicly announced or disclosed.

          (jj) No Disagreements with Accountants and Lawyers. There are no
disagreements of any kind presently existing, or reasonably anticipated by any
of the Companies to arise, between any of the Companies and the accountants and
lawyers formerly or presently employed by any of the Companies which could
affect the ability of any of the Companies to perform any of its obligations
under any of the Transaction Documents, and each of the Companies is current
with respect to any fees owed to its accountants and lawyers.

     4. COVENANTS.

it as provided in Sections 6 and 7 of this Agreement.

          (b) Form D and Blue Sky. The Companies agree to file a Form D with
respect to the Securities as required under Regulation D and to provide a copy

determine is necessary 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 on or prior to the Closing
Date. Each of the Companies 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.

file reports under the 1934 Act even if the 1934 Act or the rules and
regulations thereunder would otherwise permit such termination.

in the Registration Rights Agreement) are listed upon a national securities
exchange or automated quotation system that provides for the listing of
securities, Parent shall promptly secure the listing of all of the Registrable

notice of issuance) and shall maintain such listing of all Registrable
Securities from time to time issuable under the terms of the Transaction
Documents. Parent shall maintain the Common Stock's authorization for quotation
on the Principal Market. Neither Parent 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. Parent shall pay all
fees and expenses in connection with satisfying its obligations under this
Section 4(f).

          (g) Fees. Parent shall pay the Buyers a transaction fee and shall
reimburse the Buyers or their designee(s) for reasonable and documented costs
and expenses incurred in connection with the transactions contemplated by the
Transaction Documents (including 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 amounts, shall be withheld by Buyers from the Purchase Price
at the Closing, in accordance with the Fee Letter. Parent shall be responsible
for the payment of, and shall pay, any placement agent's fees, financial
advisory fees, or broker's commissions relating to or arising out of the
transactions contemplated hereby, and shall 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.

          (h) Pledge of Securities. Each of the Companies 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 any Company with any notice thereof or otherwise make any
delivery to any Company pursuant to this Agreement or any other Transaction
Document, including, without limitation, Section 2(f) hereof unless required in
connection with the registration of the Securities or by applicable law. Each of
the Companies 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 5:00 p.m., New York City time, on the fourth (4th) Business Day following
the date of this Agreement, Parent shall 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 (and all
schedules to this Agreement), the form of Debenture, Warrant and the
Registration Rights Agreement) (including all attachments, the "8-K Filing").
Except as set forth in the Debentures, any material non-public information
provided by any Company to any Buyer in connection with this transaction that
continues to constitute material nonpublic information on the 90th day following
the Closing shall be disclosed by Parent in a Current Report on Form 8-K filed
on such date. From and after the filing of such Form 8-K with the SEC, Parent
represents and acknowledges that no Buyer shall be in possession of any
material, nonpublic information received from any of the Companies, or any of
their respective officers, directors, employees or agents, that is not disclosed
in such Form 8-K. Each of the Companies shall not, and shall cause each of their
respective officers, directors, employees and agents not to, provide any Buyer
with any material, nonpublic information regarding Parent or any of its
Subsidiaries from and after the filing of such Form 8-K with the SEC without the
express written consent of such Buyer; provided, however, that each of the
Companies may provide a Buyer with material nonpublic information to the extent
required under the Transaction Documents, and Parent represents and acknowledges
any and all such information shall no longer constitute material nonpublic
information on the 90th day after disclosure thereof. In the event of a breach
of the foregoing covenant by any of the Companies 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 may, but shall
not be obligated to, notify Parent of such breach and the material, nonpublic
information the receipt of which resulted in such breach. Within two Business
Days of receipt of such notice, Parent shall either (a) deliver a notice to such
Buyer certifying such material, non-public information has already been publicly
disclosed by Parent or (b) make a public disclosure, in the form of a press
release, public advertisement or otherwise, of such material, nonpublic
information. Subject to the foregoing, neither any of the Companies nor any

                                       18
<PAGE>

Buyer shall issue any press releases or any other public statements with respect
to the transactions contemplated hereby; provided, however, that Parent 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 Parent in connection with any such press
release or other public disclosure prior to its release). Without the prior
written consent of any applicable Buyer, none of the Companies shall disclose
the name of any Buyer or its affiliates in any filing, announcement, release or
otherwise unless required by law.

          (j) Additional Debentures or Indebtedness. So long as any Buyer
beneficially owns any Debentures, none of the Companies will issue any
Debentures or incur any additional Indebtedness (other than to the Buyers as
contemplated hereby and Permitted Indebtedness) and none of the Companies shall
issue any other securities that would cause a breach or default under the
Debentures. For purposes hereof, "Permitted Indebtedness" means Indebtedness
incurred in the ordinary course of business consistent with past practice in an
amount not in excess of $250,000 in a single instance or $500,000 in the
aggregate during any trailing three (3) month period.

          (k) Corporate Existence. So long as any Buyer beneficially owns any
Securities, none of the Companies shall be party to any Fundamental Transaction
(as defined in the Debentures) unless each of the Companies is in compliance
with the applicable provisions governing Fundamental Transactions set forth in
the Debentures.

          (l) Incurrence of Liens. So long as any Debentures are outstanding,
none of the Companies shall directly or indirectly, allow or suffer to exist any
Lien, other than Permitted Liens (as defined in the Debentures), upon any
property or assets (including accounts and contract rights) owned by the
Companies.

          (m) Restriction on Redemption and Cash Dividends. So long as any
Debentures are outstanding, Parent 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 Debentures representing not
less than seventy percent (70%) of the aggregate principal amount of the
Debentures then outstanding (the "Required Holders").

          (n) Reservation of Shares. Parent shall take all action necessary to
at all times have authorized, and reserved for the purpose of issuance at least
110% of the number of shares of Common Stock issuable upon exercise of the
Warrants.

          (o) Conduct of Business. The business of the Companies shall not be
conducted in violation of any 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.

          (p) Additional Issuances of Securities.

               (i) For purposes of this Section 4(p), the following definitions
shall apply.

                                       19

                    (1) "Convertible Securities" means any stock or securities
          (other than Options) directly or indirectly 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) Except for a registration statement on Form S-8 for the
registration of a company stock compensation or benefit plan, from the date
hereof until 90 days following the Effective Date (as defined in the
Registration Rights Agreement), none of the Companies shall, directly or
indirectly, file any registration statement with the SEC other than the
Registration Statement (as defined in the Registration Rights Agreement).

               (iii) So long as the Debentures have not been fully repaid, none
of the Companies shall, 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 debt, equity or equity
equivalent securities, including without limitation any debt, preferred stock or
other instrument or security that may be, at any time during its life, and under
any circumstance, convertible into or exchangeable or exercisable for shares of
Common Stock or Common Stock Equivalents or debt securities (any such offer,
sale, grant, disposition or announcement being referred to as a "Subsequent
Placement") without the written consent of the Required Holders. In the event
the Required Holders do consent to the Subsequent Placement, the offering
Company shall first comply with this Section 4(p)(iii), as follows:

                    (1) Subject to the receipt by the offering Company from each
          Holder of a signed non-disclosure and confidentiality agreement which
          will, among other restrictions, preclude the Holder from trading in
          Parent stock until the information which is the subject of the Offer
          Notice is either made public or is no longer deemed to be material
          non-public information by such Company, such Company shall deliver to
          each holder of a Debenture (a "Holder") a 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 (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 Holders an
          amount equal to 50% of the Offered Securities, allocated among such
          Holders (a) based on such Holder's allocable pro rata portion of the
          aggregate principal amount of Debentures outstanding at the time of
          the Offer, and (b) with respect to each Holder that elects to purchase
          its pro rata portion of such Offered Securities, any additional
          portion of the Offered Securities attributable to the pro rata portion
          of other Holders as such Holder shall indicate it will purchase or
          acquire should the other Holders subscribe for less than their pro
          rata portions (the "Undersubscription Amount"). For purposes of this
          Agreement, a Holder's allocable pro rata portion of any Offered
          Securities shall be defined as the "Allocable Portion".

                                       20
<PAGE>

                    (2) To accept an Offer, in whole or in part, such Holder
          must deliver a written notice to such Company prior to the end of the
          fifth Business Day after such Holder's receipt of the Offer Notice
          (the "Offer Period"), setting forth the portion of such Holder's
          Allocable Portion that such Holder elects to purchase and, if such
          Holder shall elect to purchase all of its Allocable Portion, the
          Undersubscription Amount, if any, that such Holder elects to purchase
          (in either case, the "Notice of Acceptance"). If the Allocable
          Portions subscribed for by all Holders are less than the total of all
          of the Allocable Portions, then each Holder who has set forth an
          Undersubscription Amount in its Notice of Acceptance shall be entitled
          to purchase, in addition to the Allocable Portions 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 Allocable Portions and the
          Allocable Portions subscribed for (the "Available Undersubscription
          Amount"), each Holder who has subscribed for any Undersubscription
          Amount shall be entitled to purchase only that portion of the
          Available Undersubscription Amount as the Allocable Portion of such
          Holder bears to the total Allocable Portions of all Holders that have
          subscribed for Undersubscription Amounts, subject to rounding by
          Parent to the extent its deems reasonably necessary.

                    (3) Such Company shall have fifteen 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 Holders (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, interest rates and
          transaction fees) that are not more favorable to the acquiring Person
          or Persons or less favorable to such Company than those set forth in
          the Offer Notice.

                    (4) In the event such 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(p)(iii)(3) above), then each
          Holder 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 Holder elected to purchase
          pursuant to Section 4(p)(iii)(2) above multiplied by a fraction, (i)
          the numerator of which shall be the number or amount of Offered
          Securities such Company actually proposes to issue, sell or exchange
          (including Offered Securities to be issued or sold to Holders pursuant
          to Section 4(p)(iii)(3) above prior to such reduction) and (ii) the
          denominator of which shall be the original number or amount of the
          Offered Securities. In the event that any Holder so elects to reduce
          the number or amount of Offered Securities specified in its Notice of
          Acceptance, such 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 Holders in accordance
          with Section 4(p)(iii)(1) above.

                                       21
<PAGE>

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

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

               (iv) The restrictions contained in subsections (ii) and (iii) of
this Section 4(p) shall not apply in connection with the issuance of any Common
Stock Equivalents issued pursuant to a employee benefit plan which has been
approved by the Board of Directors of Parent.

          (q) U.S. Real Property Holding Corporation. None of the Companies
shall become a U.S. real property holding corporation within the meaning of
Section 897 of the Internal Revenue Code of 1986, as amended.

     5. REGISTERS; TRANSFER AGENT INSTRUCTIONS.

          (a) Registers. The Companies shall maintain at their principal
executive offices (or such other office or agency of the Companies as they may
designate by notice to each holder of Securities), a register for the Debentures
in which each Company shall record the name and address of the Person in whose
name the Debentures have been issued (including the name and address of each
transferee) and the principal amount of Debentures held by such Person. Each of
the Companies shall keep the register open and available at all times during
business hours for reasonable advance notice inspection of any Buyer or its
legal representatives. Parent shall maintain at its principal executive offices
(or such other office or agency of Parent as it may designate by notice to each
holder of Securities), a register for the Warrants in which Parent shall record
the name and address of the Person in whose name the Warrants have been issued
(including the name and address of each transferee) and the number of Warrants
held by such Person. Parent shall keep the register open and available at all
times during business hours for reasonable advance notice inspection of any
Buyer or its legal representatives.

          (b) Maintenance of Registers. Notwithstanding anything to the contrary
contained herein, the Debentures are registered obligations and the right,
title, and interest of the Buyer and its assignees in and to such Debentures
shall be transferable only upon notation of such transfer in the Register. The
Debentures shall only evidence the Buyer's or its assignee's right, title and
interest in and to the related Debentures, and in no event is any such Debenture
to be considered a bearer instrument or obligation. This Section 5(b) shall be
construed so that the Debentures are at all times maintained in "registered
form" within the meaning of Sections 163(f), 871(h)(2) and 881(c)(2) of the
Internal Revenue Code of 1986, as amended, and any related Treasury Regulations
promulgated thereunder. The Company hereby appoints the Sandhurst Asset
Management, LLC to act as its agent for purposes of maintaining such notations
of transfer in the Register. The other Buyers hereby accept such appointment

                                       22
<PAGE>

          (c) Transfer Agent Instructions. Parent 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 Warrant Shares in such amounts as specified from
time to time by each Buyer to Parent in the form of Exhibit G attached hereto
(the "Irrevocable Transfer Agent Instructions"). Parent 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 Sections
2(e) and 2(f) hereof, will be given by Parent to its transfer agent with respect
to the Warrant Shares, and that the Warrant Shares shall otherwise be freely
transferable on the books and records of Parent, as applicable, and to the
extent provided in this Agreement and the other Transaction Documents. If a
Buyer effects a sale, assignment or transfer of Warrant Shares in accordance
with Sections 2(e) and 2(f), Parent 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 Warrant Shares sold,
assigned or transferred 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. Each Company acknowledges that a breach by it of its obligations
hereunder will cause irreparable harm to a Buyer. Accordingly, each 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 Parent or any Company of the provisions of this Section
5(b), that a Buyer shall be entitled, in addition to all other available
remedies, to seek 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 COMPANIES' OBLIGATIONS TO SELL.

          (a) The obligations of the Companies hereunder to issue and sell the
Debentures and Warrants to each Buyer at the Closing is subject to the

Letter") set forth on Exhibit K attached hereto.

<PAGE>

               (viii) The representations and warranties of each Company shall
be true and correct as of the date when made and as of the Closing Date as
though made at that time (except for representations and warranties that speak
as of a specific date, which shall be true and correct as of such specific
date), and each Company shall have performed, satisfied and complied in all
respects with the covenants, agreements and conditions required by the

               (xi) Each of the Companies shall have obtained all governmental,

     8. TERMINATION.

          In the event that the Closing shall not have occurred with respect to
a Buyer on or before five Business Days from the date hereof due to any
Company's or such Buyer's failure to satisfy the conditions set forth in
Sections 6 and 7 above (and the nonbreaching party's failure to waive such
unsatisfied condition(s)), the nonbreaching party shall have the option to
terminate this Agreement with respect to such breaching party at the close of

provided, however, if this Agreement is terminated pursuant to this Section 8,
the Companies shall remain obligated to reimburse the non-breaching Buyers the

     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

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
irrevocably waives personal service of process and consents to process being
served in any such suit, action or proceeding by mailing a copy thereof to such
party at the address for such notices to it under this Agreement and agrees that
such service shall constitute good and sufficient service of process and notice
thereof. Nothing contained herein shall be deemed to limit in any way any right
to serve process in any manner permitted by law. EACH PARTY HEREBY IRREVOCABLY
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
THIS AGREEMENT OR ANY TRANSACTION CONTEMPLATED HEREBY.

          (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 each 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 Companies, 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, none of the Companies or 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
Companies and the Required Holders, 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 or Holders of Debentures, as the case may be. None of
the Companies has, 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, each of the Companies 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 Companies or otherwise.

waiver or other communication, (B) mechanically or electronically generated by
the sender's facsimile machine containing the time, date, recipient facsimile
number and an image of the first page of such transmission or (C) provided by an
overnight courier service shall be rebuttable evidence of personal service,
receipt by facsimile or receipt from an overnight courier service in accordance
with clauses (i), (ii) or (iii) above, respectively.

          (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 Debentures or Warrants. None of the Companies
shall assign this Agreement or any rights or obligations hereunder without the
prior written consent of the each of the Holders of the Debentures and Warrants,
including by way of a Fundamental Transaction (unless the Companies are in
compliance with the applicable provisions governing Fundamental Transactions set
forth in the Debentures). A Buyer may assign some or all of its rights hereunder
in connection with transfer of any of its Securities without the consent of the
Companies, in which event such assignee shall be deemed to be a Buyer hereunder
with respect to such assigned rights, and the Companies shall use their best
efforts to ensure that such transferee is registered as a Holder and that any
Liens on the Collateral shall be transferred to such Holder.

          (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 Companies 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 Companies' other obligations under the Transaction
Documents, each Company shall jointly and severally 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)

                                       29
<PAGE>

any misrepresentation or breach of any representation or warranty made by the
Companies 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 Companies 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 Companies) 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
indirectly, with the proceeds of the issuance of the Securities, (iii) any
disclosure made to such Buyer pursuant to Section 4(i), or (iv) the status of
such Buyer or holder of the Securities as an investor in the Companies pursuant
to the transactions contemplated by the Transaction Documents. To the extent
that the foregoing undertakings by the Companies may be unenforceable for any
reason, the Companies shall make the maximum contribution to the payment and
satisfaction of each of the Indemnified Liabilities which is permissible under
applicable law. The indemnification provided in this Section 9(k) shall not
apply to any Indemnified Liabilities which are the subject of the
indemnification provided for in Section 6 of the Registration Rights Agreement,
as well as shall not apply to those matters covered by the express exceptions to
indemnification provided by Section 6 of the Registration Rights Agreement.
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.

          (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, each of
the Companies 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. Each of the
Companies 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) Payment Set Aside. To the extent that the Companies 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 Companies, a

                                       30
<PAGE>

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.

          (o) 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 each of the
Companies acknowledges that 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.
