                          SECURITIES PURCHASE AGREEMENT

         This SECURITIES PURCHASE AGREEMENT (the "AGREEMENT"), dated as of
October 4, 2004, is made by and among NGAS Resources, Inc., a corporation
organized under the laws of British Columbia, Canada (the "COMPANY"), the
purchaser (the "PURCHASER") set forth on the execution pages hereof (each, an
"EXECUTION PAGE" and collectively the "EXECUTION PAGES").

                                   BACKGROUND

         A. The Company and the Purchaser are executing and delivering this
Agreement in reliance upon the exemption from securities registration afforded
by the provisions of Regulation D ("REGULATION D"), as promulgated by the United
States Securities and Exchange Commission (the "SEC") under the Securities Act
of 1933, as amended (the "SECURITIES ACT").

         B. Upon the terms and conditions stated in this Agreement, the Company
desires to issue and sell to the Purchaser, and the Purchaser desires to
purchase, units (the "UNITS"), each Unit consisting of (i) a convertible
promissory note, in the form attached hereto as Exhibit A (the "NOTES"), in the
principal face amount of $1,000.00, which Notes shall be initially convertible
into approximately 166.667 shares of the Company's common stock, no par value
per share (the "COMMON STOCK"), per $1,000.00 of principal face amount of Notes
(as may be adjusted from time to time), and (ii) a warrant, in the form attached
hereto as Exhibit B (the "WARRANTS"), to acquire initially approximately 72.131
shares of Common Stock. The shares of Common Stock issuable upon conversion of
or otherwise pursuant to the Notes are referred to herein as the "CONVERSION
SHARES" and the shares of Common Stock issuable upon exercise of or otherwise
pursuant to the Warrants are referred to herein as the "WARRANT SHARES." The
Notes, the Warrants, the Conversion Shares and the Warrant Shares are
collectively referenced herein as the "SECURITIES" and each of them may
individually be referred to herein as a "SECURITY."

         C. Contemporaneously with the execution and delivery of this Agreement,
the parties hereto are executing and delivering a Registration Rights Agreement,
in the form attached hereto as Exhibit C (the "REGISTRATION RIGHTS AGREEMENT"),
pursuant to which the Company has agreed to provide certain registration rights
under the Securities Act and the rules and regulations promulgated thereunder,
and applicable state securities laws. This Agreement, the Notes, the Warrants
and the Registration Rights Agreement are collectively referred to herein as the
"TRANSACTION DOCUMENTS."

         NOW, THEREFORE, in consideration of the premises and mutual covenants
contained herein and other good and valuable consideration, the receipt and
sufficiency of which are hereby acknowledged, the Company and the Purchaser,
intending to be legally bound, hereby agree as follows:

Execution Page, for a purchase price (the "PURCHASE PRICE") per Unit equal to
One Thousand Dollars ($1,000.00). The aggregate amount of Units to be issued and
sold by the Company to the Purchaser pursuant to this Agreement shall not exceed
Six Million Two Hundred and Fifty Thousand Dollars ($6,100,000.00).

2.       PURCHASER'S REPRESENTATIONS AND WARRANTIES.

         The Purchaser represents and warrants to the Company as follows:

         (a) Purchase for Own Account, Etc. The Purchaser is purchasing the
Securities for such Purchaser's own account for investment purposes only and not
with a present view towards the public sale or distribution thereof, except
pursuant to sales that are exempt from the registration requirements of the
Securities Act and/or sales registered under the Securities Act. Such Purchaser
understands that such Purchaser must bear the economic risk of this investment
indefinitely, unless the Securities are registered pursuant to the Securities
Act and any applicable state securities or blue sky laws or an exemption from
such registration is available, and that the Company has no present intention of
registering the resale of any such Securities other than as contemplated by the
Registration Rights Agreement. Notwithstanding anything in this Section 2(a) to
the contrary, by making the representations herein, such Purchaser does not
agree to hold 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 from the registration
requirements under the Securities Act.

         (b) Accredited Investor Status. The Purchaser is an "Accredited
Investor" as that term is defined in Rule 501(a) of Regulation D.

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

         (d) Information. The Purchaser and its counsel, if any, have been
furnished 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 specifically requested by such Purchaser or its counsel. Neither such
inquiries nor any other investigation conducted by such Purchaser or its counsel
or any of its representatives shall modify, amend or affect such Purchaser's
right to rely on the Company's representations and warranties contained in
Section 3 below. The Purchaser understands that such Purchaser's investment in
the Securities involves a high degree of risk.

         (e) Governmental Review. The Purchaser understands that no United
States federal or state agency or any other government or governmental agency
has passed upon or made any recommendation or endorsement of the Securities.

         (f) Authorization; Enforcement. This Agreement and the Registration
Rights Agreement have been duly and validly authorized, executed and delivered
on behalf of the Purchaser and are valid and binding agreements of such
Purchaser enforceable against such Purchaser in accordance with their respective
terms.

         (g) Residency. The Purchaser is a resident of the jurisdiction set
forth under such Purchaser's name on the Execution Page hereto executed by such
Purchaser.

         (h) Transactions in the Company's Common Stock. The Purchaser has not
effected any purchases or sales of the Company's Common Stock during the five
trading days (as hereinafter defined) prior to the date hereof. For purposes of
this subsection (h), the term "trading day" means any day on which the SmallCap
Market is open for trading.

         The Purchaser's representations and warranties made in this Article 2
are made solely for the purpose of permitting the Company to make a
determination that the offer and sale of the Securities pursuant to this
Agreement comply with applicable U.S. federal and state securities laws and not
for any other purpose. Accordingly, the Company may not rely on such
representations and warranties for any other purpose. No Purchaser has made or
hereby makes any other representations or warranties, express or implied, to the
Company in connection with the transactions contemplated hereby.

3.       REPRESENTATIONS AND WARRANTIES OF THE COMPANY.

         Except as set forth on a Disclosure Schedule executed and delivered by
the Company to the Purchaser dated the date hereof (the "DISCLOSURE SCHEDULE"),
the Company represents and warrants to the Purchaser as follows:

         (a) Organization and Qualification. The Company and each of its direct
and indirect subsidiaries (collectively, the "SUBSIDIARIES") is a corporation
duly organized and existing in good standing under the laws of the jurisdiction
in which it is incorporated or organized, and has the requisite corporate power
to own its properties and to carry on its business as now being conducted. The
Company and each of its Subsidiaries is duly qualified as a foreign corporation
to do business and is in good standing in every jurisdiction in which the nature
of the business conducted by it makes such qualification necessary and where the
failure so to qualify or be in good standing would have a Material Adverse
Effect. For purposes of this Agreement, "MATERIAL ADVERSE EFFECT" means any
effect which, individually or in the aggregate with all other effects,
reasonably would be expected to be materially adverse to (i) the Securities,
(ii) the ability of the Company to perform its obligations under this Agreement
or the other Transaction Documents or (iii) the business, operations,
properties, prospects, financial condition or results of operations of the
Company and its Subsidiaries, taken as a whole.

         (b) Authorization; Enforcement. (i) The Company has the requisite
corporate power and authority to enter into and perform its obligations under
this Agreement and the other Transaction Documents, to issue and sell the Units
in accordance with the terms hereof, to issue the Conversion Shares upon
conversion of the Notes in accordance with the terms thereof and to issue the
Warrant Shares upon exercise of the Warrants in accordance with the terms
thereof; (ii) the execution, delivery and performance of this Agreement and the
other Transaction Documents by the Company and the consummation by it of the
transactions contemplated hereby and thereby (including, without limitation, the
issuance of the Units and the issuance and reservation for issuance of the
Conversion Shares and Warrant Shares) have been duly authorized by the Company's
Board of Directors and no further consent or authorization of the Company, its
Board of Directors, or any committee of the Board of Directors is required, and
(iii) this Agreement constitutes, and, upon execution and delivery by the
Company of the other Transaction Documents, such Transaction Documents will
constitute, valid and binding obligations of the Company enforceable against the
Company in accordance with their respective terms. Neither the execution,
delivery or performance by the Company of its obligations under this Agreement
or the other Transaction Documents, nor the consummation by it of the
transactions contemplated hereby or thereby (including, without limitation, the
issuance of the Units or the issuance or reservation for issuance of the
Conversion Shares or Warrant Shares) requires any consent or authorization of
the Company's stockholders (including, without limitation, any consent under
Rule 4350(i) of the National Association of Securities Dealers, Inc.).

         (c) Capitalization. The capitalization of the Company as of the date
hereof, including the authorized capital stock, the number of shares issued and
outstanding, the number of shares issuable and reserved for issuance pursuant to
the Company's stock option plans, the number of shares issuable and reserved for
issuance pursuant to securities (other than the Notes and the Warrants)
exercisable or exchangeable for, or convertible into, any shares of capital
stock and the number of shares to be reserved for issuance upon conversion of
the Notes and exercise of the Warrants is set forth in Section 3(c) of the
Disclosure Schedule. All of such outstanding shares of capital stock have been,
or upon issuance in accordance with the terms of any such exercisable,
exchangeable or convertible securities will be, validly issued, fully paid and
non-assessable. No shares of capital stock of the Company (including the
Conversion Shares and the Warrant Shares) are subject to preemptive rights or
any other similar rights of the stockholders of the Company or any liens or
encumbrances. Except for the Securities and as set forth in Section 3(c) of the
Disclosure Schedule, (i) there are no outstanding options, warrants, scrip,
rights to subscribe to, calls or commitments of any character whatsoever
relating to, or securities or rights convertible into or exercisable or
exchangeable for, any shares of capital stock of the Company or any of its
Subsidiaries, or contracts, commitments, understandings or arrangements by which
the Company or any of its Subsidiaries is or may become bound to issue
additional shares of capital stock of the Company or any of its Subsidiaries,
nor are any such issuances, contracts, commitments, understandings or
arrangements contemplated, (ii) there are no contracts, commitments,
understandings or arrangements under which the Company or any of its
Subsidiaries is obligated to register the sale of any of its or their securities
under the Securities Act (except the Registration Rights Agreement); (iii) there
are no outstanding securities or instruments of the Company or any of its
Subsidiaries which contain any redemption or similar provisions, and there are
no contracts, commitments, understandings or arrangements by which the Company
or any of its Subsidiaries is or may become bound to redeem or otherwise acquire
any security of the Company or

                                       3
<PAGE>

any of its Subsidiaries; and (iv) the Company does not have any shareholder
rights plan, "poison pill" or other anti-takeover plans or similar arrangements.
Section 3(c) of the Disclosure Schedule sets forth all of the securities or
instruments issued by the Company or any of its Subsidiaries that contain
anti-dilution or similar provisions, and, except as and to the extent set forth
thereon, the sale and issuance of the Securities will not trigger any
anti-dilution adjustments to any such securities or instruments. The Company has
furnished to the Purchaser true and correct copies of the Company's
organizational documents ("ORGANIZATIONAL DOCUMENTS") as in effect on the date
hereof and all other instruments and agreements governing securities convertible
into or exercisable or exchangeable for capital stock of the Company, all of
which instruments and agreements are set forth in Section 3(c) of the Disclosure
Schedule. 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 any such Subsidiary.

         (d) Issuance of Securities. The Units are duly authorized and, upon
issuance in accordance with the terms of this Agreement, (i) will be validly
issued, fully paid and non-assessable and free from all taxes, liens, claims and
encumbrances, (ii) will not be subject to preemptive rights, rights of first
refusal or other similar rights of stockholders of the Company or any other
person and (iii) will not impose personal liability on the holder thereof. The
Conversion Shares and Warrant Shares are duly authorized and reserved for
issuance, and, upon conversion of the Notes and exercise of the Warrants in
accordance with the terms thereof, (I) will be validly issued, fully paid and
non-assessable, and free from all taxes, liens, claims and encumbrances, (II)
will not be subject to preemptive rights, rights of first refusal or other
similar rights of stockholders of the Company or any other person and (III) will
not impose personal liability upon the holder thereof.

         (e) No Conflicts. The execution, delivery and performance of this
Agreement and the other 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 Units and the issuance and
reservation for issuance of the Conversion Shares and Warrant Shares) will not
(i) result in a violation of the Organizational Documents, (ii) conflict with,
or constitute a default (or an event that with notice or lapse of time or both
would become a default) under, or give to others any rights of termination,
amendment (including, without limitation, the triggering of any anti-dilution
provisions), 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 United States federal and state securities laws, rules and
regulations and rules and regulations of any self-regulatory organizations to
which either the Company or its securities are subject) 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, with respect to
clauses (ii) and (iii), for such conflicts, defaults, terminations, amendments,
accelerations, cancellations and violations that would not, individually or in
the aggregate, have a Material Adverse Effect).

(f) Compliance. The Company is not in violation of the Organizational Documents,
and no Subsidiary is in violation of its organizational documents. Neither the
Company nor any of its Subsidiaries is in default (and no event has occurred
that with notice or lapse of time or both would put the Company or any of its
Subsidiaries in default) under, nor has there occurred any event giving others
(with notice or lapse of time or both) any rights of termination, amendment,
acceleration or cancellation of, any agreement, indenture or instrument to which
the Company or any of its Subsidiaries is a party (including, without
limitation, the Contracts (as defined in Section 3(g) below)), except for actual
or possible violations, defaults or rights that would not, individually or in
the aggregate, have a Material Adverse Effect. The businesses of the Company and
its Subsidiaries are not being conducted, and shall not be conducted so long as
the Purchaser owns any of the Securities, in violation of any law, ordinance or
regulation of any governmental entity, except for possible violations the
sanctions for which either individually or in the aggregate have not had and
would not have a Material Adverse Effect. Neither the Company, nor any of its
Subsidiaries, nor any director, officer, agent, employee or other person acting
on behalf of the Company or any Subsidiary has, in the course of his actions
for, or on behalf of, the Company or any Subsidiary, used any corporate funds
for any unlawful contribution, gift, entertainment or other unlawful expenses
relating to political activity, made any direct or indirect unlawful payment to
any foreign or domestic government official or employee from corporate funds,
violated or is in violation of any provision of the U.S. Foreign Corrupt
Practices Act of 1977, or made any bribe, rebate, payoff, influence payment,
kickback or other unlawful payment to any foreign or domestic government
official or employee. The Company and its Subsidiaries possess all certificates,
authorizations and permits issued by the appropriate federal, state, provincial
or foreign regulatory authorities that are material to the conduct of its
business, and neither the Company nor any of its Subsidiaries has received any
notice of

                                       4
<PAGE>

proceeding relating to the revocation or modification of any such certificate,
authorization or permit. Except (i) as may be required under the Securities Act
in connection with the performance of the Company's obligations under the
Registration Rights Agreement, (ii) for the filing of a Form D with the SEC,
(iii) as may be required for compliance with applicable state securities or
"blue sky" laws, or (iv) as otherwise set forth in Section 3(f) of the
Disclosure Schedule, the Company is not required to obtain any consent,
approval, authorization or order of, or make any filing or registration with,
any court or governmental agency or any regulatory or self-regulatory agency or
other third party in order for it to execute, deliver or perform any of its
obligations under this Agreement or any of the other Transaction Documents.

         (g) SEC Documents, Financial Statements. Since December 31, 1998, the
Company has timely filed (within applicable extension periods) all reports,
schedules, forms, statements and other documents required to be filed by it with
the SEC pursuant to the reporting requirements of the Securities Exchange Act of
1934, as amended (the "EXCHANGE Act") (all of the foregoing filed prior to the
date hereof and all exhibits included therein and financial statements and
schedules thereto and documents incorporated by reference therein, the "SEC
DOCUMENTS"). The Company has delivered to the Purchaser true and complete copies
of the SEC Documents. As of their respective dates, the SEC Documents complied
in all material respects with the requirements of the Exchange Act or the
Securities Act, as the case may be, 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 light of
the circumstances under which they were made, not misleading. None of the
statements made in any such SEC Documents is, or has been, required to be
amended or updated under applicable law (except for such statements as have been
amended or updated in subsequent filings made prior to the date hereof). 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
applicable with respect thereto. Such financial statements have been prepared in
accordance with U.S. generally accepted accounting principles ("GAAP"),
consistently applied, during the periods involved (except as may be otherwise
indicated in such financial statements or the notes thereto or, in the case of
unaudited interim statements, to the extent they may not include footnotes or
may be condensed or summary statements) and fairly present in all material
respects the consolidated financial position of the Company and its consolidated
Subsidiaries as of the dates thereof and the consolidated results of their
operations and cash flows for the periods then ended (subject, in the case of
unaudited statements, to normal, immaterial year-end audit adjustments). Except
as set forth in the financial statements of the Company included in the Select
SEC Documents (as defined below), the Company has no liabilities, contingent or
otherwise, other than (i) liabilities incurred in the ordinary course of
business subsequent to the date of such financial statements and (ii)
obligations under contracts and commitments incurred in the ordinary course of
business and not required under GAAP to be reflected in such financial
statements, which liabilities and obligations referred to in clauses (i) and
(ii), individually or in the aggregate, are not material to the financial
condition or operating results of the Company. To the extent required by the
rules and regulations of the SEC applicable thereto, the Select SEC Documents
contain a complete and accurate list of all material undischarged written or
oral contracts, agreements, leases or other instruments to which the Company or
any Subsidiary is a party or by which the Company or any Subsidiary is bound or
to which any of the properties or assets of the Company or any Subsidiary is
subject (each, a "CONTRACT"). Except as set forth in the Select SEC Documents,
none of the Company, its Subsidiaries or, to the best knowledge of the Company,
any of the other parties thereto is in breach or violation of any Contract,
which breach or violation would have a Material Adverse Effect. For purposes of
this Agreement, "SELECT SEC DOCUMENTS" means the Company's (A) Proxy Statement
for its 2004 Annual Meeting, (B) Annual Report on Form 10-K for the fiscal year
ended December 31, 2003 (the "2003 ANNUAL REPORT"), (C) Quarterly Reports on
Form 10-Q for the fiscal quarters ended March 31, 2004 and June 30, 2004, and
(D) Current Reports on Form 8-K filed since December 31, 2003.

         (h) Internal Accounting Controls. The Company and each of its
Subsidiaries maintains a system of internal accounting controls sufficient to
provide reasonable assurance that (i) transactions are executed in accordance
with management's general or specific authorizations, (ii) transactions are
recorded as necessary to permit preparation of financial statements in
conformity with GAAP and to maintain asset accountability, (iii) access to
assets is permitted only in accordance with management's general or specific
authorization, and (iv) the recorded accountability for assets is compared with
the existing assets at reasonable intervals and appropriate action is taken with
respect to any differences. The Company has established disclosure controls and
procedures (as defined in Exchange Act Rules 13a-14 and 15d-14) for the Company
and designed such disclosures controls and procedures to ensure that material
information relating to the Company, including its Subsidiaries, is made known
to

                                       5
<PAGE>

the certifying officers by others within those entities, particularly during the
period in which the Company's Annual Report on Form 10-K or Quarterly Report on
Form 10-Q, as the case may be, is being prepared. The Company's certifying
officers have evaluated the effectiveness of the Company's controls and
procedures as of the date of the end of the period covered by the 2003 Annual
Report and the Company's most recently filed Quarterly Report on Form 10-Q (each
such date, an "EVALUATION DATE"). The Company presented in the 2003 Annual
Report and its most recently filed Quarterly Report on Form 10-Q the conclusions
of the certifying officers about the effectiveness of the disclosure controls
and procedures based on their evaluations as of the respective Evaluation Date.
Since the Evaluation Date for the 2003 Annual Report, there have been no
significant changes in the Company's internal controls (as such term is defined
in Item 307(b) of Regulation S-K under the Exchange Act) or, to the Company's
knowledge, in other factors that could significantly affect the Company's
internal controls.

         (i) Absence of Certain Changes. Except as set forth in the Select SEC
Documents, since December 31, 2003, there has been no material adverse change
and no material adverse development in the business, properties, operations,
prospects, financial condition or results of operations of the Company and its
Subsidiaries, taken as a whole. The Company has not taken any steps, and does
not currently expect to take any steps, to seek protection pursuant to any
bankruptcy or receivership law, nor does the Company or any of its Subsidiaries
have any knowledge or reason to believe that its creditors intend to initiate
involuntary bankruptcy proceedings with respect to the Company or any of its
Subsidiaries.

         (j) Transactions With Affiliates. Except as set forth in the Select SEC
Documents, none of the officers, directors, or employees of the Company or any
of its Subsidiaries is presently a party to any transaction with the Company or
any of its Subsidiaries (other than for ordinary course services solely in their
capacity as officers, directors or employees), including any contract, agreement
or other arrangement providing for the furnishing of services to or by,
providing for rental of real or personal property to or from, or otherwise
requiring payments to or from any such officer, director or employee or any
corporation, partnership, trust or other entity in which any such officer,
director, or employee has an ownership interest of five percent or more or is an
officer, director, trustee or partner.

         (k) Absence of Litigation. Except as disclosed in the Select SEC
Documents, there is no action, suit, proceeding, inquiry or investigation before
or by any court, public board, government agency, self-regulatory organization
or body (including, without limitation, the SEC) pending or, to the knowledge of
the Company or any of its Subsidiaries, threatened against or affecting the
Company, any of its Subsidiaries, or any of their respective directors or
officers in their capacities as such. There are no facts which, if known by a
potential claimant or governmental authority, could give rise to a claim or
proceeding which, if asserted or conducted with results unfavorable to the
Company or any of its Subsidiaries, could reasonably be expected to have a
Material Adverse Effect. The SEC has not issued any stop order or other order
suspending the effectiveness of any registration statement filed by the Company
or any Subsidiary under the Securities Act or the Exchange Act.

(l) Intellectual Property. Each of the Company and its Subsidiaries owns or is
duly licensed (and, in such event, has the unfettered right to grant
sublicenses) to use all patents, patent applications, trademarks, trademark
applications, trade names, service marks, copyrights, copyright applications,
licenses, permits, inventions, discoveries, processes, scientific, technical,
engineering and marketing data, object and source codes, know-how (including
trade secrets and other unpatented and/or unpatentable proprietary or
confidential information, systems or procedures) and other similar rights and
proprietary knowledge (collectively, "INTANGIBLES") necessary for the conduct of
its business as now being conducted and as presently contemplated to be
conducted in the future. Section 3(l) of the Disclosure Schedule sets forth a
list of all Intangibles owned and/or used by the Company in its business. To the
knowledge of the Company and its Subsidiaries, neither the Company nor any
Subsidiary of the Company infringes or is in conflict with any right of any
other person with respect to any third party Intangibles. Neither the Company
nor any of its Subsidiaries has received written notice of any pending conflict
with or infringement upon such third party Intangibles. Neither the Company nor
any of its Subsidiaries has entered into any consent agreement, indemnification
agreement, forbearance to sue or settlement agreement with respect to the
validity of the Company's or its Subsidiaries' ownership of or right to use its
Intangibles and there is no reasonable basis for any such claim to be
successful. The Intangibles are valid and enforceable and no registration
relating thereto has lapsed, expired or been abandoned or canceled or is the
subject of cancellation or other adversarial proceedings, and all applications
therefor are pending and in good standing. The Company and its Subsidiaries have
complied, in all material respects, with their respective contractual
obligations relating to the protection of the Intangibles used

                                       6
<PAGE>

pursuant to licenses. No person is infringing on or violating the Intangibles
owned or used by the Company or its Subsidiaries.

         (m) Title. The Company and its Subsidiaries have good and marketable
title in fee simple to all real property and good and merchantable title to all
personal property owned by them that 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 materially interfere with the use made and proposed to be made of such
property by the Company and its Subsidiaries. Any real property and facilities
held under lease by the Company and its Subsidiaries are held by them under
valid, subsisting and enforceable leases with such exceptions as are not
material and do not materially interfere with the use made and proposed to be
made of such property and buildings by the Company and its Subsidiaries.

         (n) Tax Status. Except as set forth in the Select SEC Documents, the
Company and each of its Subsidiaries has made or filed all foreign, U.S.
federal, state, provincial and local income and all other tax returns, reports
and declarations required by any jurisdiction to which it is subject (unless and
only to the extent that the Company and each of its Subsidiaries has set aside
on its books provisions reasonably adequate for the payment of all unpaid and
unreported taxes) and 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 has set aside on its books provisions 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. The Company has not executed a
waiver with respect to any statute of limitations relating to the assessment or
collection of any foreign, federal, state, provincial or local tax. None of the
Company's tax returns is presently being audited by any taxing authority.

         (o) Key Employees. Each of the Company's directors and officers and any
Key Employee (as defined below) is currently serving the Company in the capacity
disclosed in the Select SEC Documents. No Key Employee 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 Key Employee does not subject the
Company or any of its Subsidiaries to any material liability with respect to any
of the foregoing matters. No Key Employee has, to the knowledge of the Company
and its Subsidiaries, any intention to terminate or limit his employment with,
or services to, the Company or any of its Subsidiaries, nor is any such Key
Employee subject to any constraints which would cause such employee to be unable
to devote his full time and attention to such employment or services. For
purposes of this Agreement, "KEY EMPLOYEE" means the persons listed in Section
3(o) of the Disclosure Schedule and any individual who assumes or performs any
of the duties of a Key Employee.

         (p) Employee Relations. (i) Neither the Company nor any of its
Subsidiaries is involved in any material union labor dispute nor, to the
knowledge of the Company or any of its Subsidiaries, is any such dispute
threatened. The Company and its Subsidiaries believe that their relations with
their employees are good; (ii) no executive officer (as defined in Rule 501(f)
of the Securities Act) has notified the Company that such officer intends to
leave the Company or otherwise terminate such officer's employment with the
Company; and (iii) the Company and its Subsidiaries are in compliance with all
federal, state, local and foreign laws and regulations respecting employment and
employment practices, terms and conditions of employment and wages and hours,
except where failure to be in compliance would not, either individually or in
the aggregate, result in a Material Adverse Effect.

         (q) Insurance. The Company and each of its Subsidiaries has in force
fire, casualty, product liability and other insurance policies, with extended
coverage, sufficient in amount to allow it to replace any of its material
properties or assets which might be damaged or destroyed or sufficient to cover
liabilities to which the Company may reasonably become subject, and such types
and amounts of other insurance with respect to its business and properties, on
both a per occurrence and an aggregate basis, as are customarily carried by
persons engaged in the same or similar business as the Company. No default or
event has occurred that could give rise to a default under any such policy.

         (r) Environmental Matters. There is no environmental litigation or
other environmental proceeding pending or, to the knowledge of the Company or
any of its Subsidiaries, threatened by any governmental regulatory authority or
others with respect to the current or any former business of the Company or any
of its Subsidiaries or

                                       7
<PAGE>

any partnership or joint venture currently or at any time affiliated with the
Company or any of its Subsidiaries. No state of facts exists as to environmental
matters or Hazardous Substances (as defined below) that involves the reasonable
likelihood of a material capital expenditure by the Company or any of its
Subsidiaries that may otherwise have a Material Adverse Effect. No Hazardous
Substances have been treated, stored or disposed of, or otherwise deposited, in
or on the properties owned or leased by the Company or any of its Subsidiaries
or by any partnership or joint venture currently or at any time affiliated with
the Company or any of its Subsidiaries in violation of any applicable
environmental laws. The environmental compliance programs of the Company and
each of its Subsidiaries comply in all respects with all environmental laws,
whether foreign, federal, state, provincial or local, currently in effect. For
purposes of this Agreement, "HAZARDOUS SUBSTANCES" means any substance, waste,
contaminant, pollutant or material that has been determined by any governmental
authority to be capable of posing a risk of injury to health, safety, property
or the environment.

         (s) Solvency. Based on the financial condition of the Company as of the
Closing Date, (i) the Company's fair saleable value of its assets exceeds the
amount that will be required to be paid on or in respect of the Company's
existing debts and other liabilities (including known contingent liabilities) as
they mature; (ii) the Company's assets do not constitute unreasonably small
capital to carry on its business for the current fiscal year as now conducted
and as proposed to be conducted including its capital needs taking into account
the particular capital requirements of the business conducted by the Company,
and projected capital requirements and capital availability thereof; and (iii)
the current cash flow of the Company, together with the proceeds the Company
would receive, were it to liquidate all of its assets, after taking into account
all anticipated uses of the cash, would be sufficient to pay all amounts on or
in respect of its debt when such amounts are required to be paid. The Company
does not intend 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).

         (t) Listing. The Common Stock is currently listed for trading on the
Nasdaq SmallCap Market (the "SMALLCAP MARKET"). The Company is not in violation
of the listing requirements of the SmallCap Market, does not reasonably
anticipate that the Common Stock will be delisted by the SmallCap Market for the
foreseeable future, and has not received any notice regarding the possible
delisting of the Common Stock from the SmallCap Market. The Company has secured
the listing of the Conversion Shares and Warrant Shares on the SmallCap Market
and on each other national securities exchange, automated quotation system or
over-the-counter market upon which shares of Common Stock are currently listed
(subject to official notice of issuance).

         (u) Form S-3 Eligibility. The Company is eligible to register the
resale of its Common Stock on a registration statement on Form S-3 under the
Securities Act. There exist no facts or circumstances that would prohibit or
delay the preparation and filing of a registration statement on Form S-3 with
respect to the Registrable Securities (as defined in the Registration Rights
Agreement). The Company has no basis to believe that its past or present
independent public auditors will withhold their consent to the inclusion, or
incorporation by reference, of their audit opinion concerning the Company's
financial statements which are included in the Registration Statement required
to be filed pursuant to the Registration Rights Agreement.

         (v) Anti-Takeover Provisions. 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 its Organizational Documents or the laws of the jurisdiction of its
organization which is or could become applicable to the Purchaser as a result of
the transactions contemplated by this Agreement, including, without limitation,
the Company's issuance of the Securities or any other securities pursuant to the
terms of this Agreement and any and all Purchaser's ownership of the Securities
or any such other securities.

         (w) Acknowledgment Regarding the Purchaser's Purchase of the
Securities. The Company acknowledges and agrees that the Purchaser is acting
solely in the capacity of arm's length purchaser with respect to this Agreement
and the other Transaction Documents and the transactions contemplated hereby and
thereby, and that no Purchaser is (i) an officer or director of the Company,
(ii) an "affiliate" of the Company (as defined in Rule 144) or (iii) a
"beneficial owner" of more than 5% of the Common Stock (as defined for purposes
of Rule 13d-3 of the Exchange Act). The Company further acknowledges that no
Purchaser is acting as a financial advisor or fiduciary of the Company (or in
any similar capacity) with respect to this Agreement or the other Transaction
Documents and the transactions contemplated hereby and thereby, and any advice
given by the Purchaser or any of its representatives or agents in connection
with this Agreement or the other Transaction Documents and the

                                       8
<PAGE>

transactions contemplated hereby and thereby is merely incidental to such
Purchaser's purchase of the Securities. The Company further represents to the
Purchaser that the Company's decision to enter into this Agreement and the other
Transaction Documents has been based solely on the independent evaluation by the
Company and its representatives.

         (x) No General Solicitation or Integrated Offering. Neither the Company
nor any distributor participating on the Company's behalf in the transactions
contemplated hereby (if any) nor any person acting for the Company, or any such
distributor, has conducted any "general solicitation" (as such term is defined
in Regulation D) with respect to any of the Securities being offered hereby.
Neither the Company nor any of its affiliates, nor any person acting on its or
their behalf, has directly or indirectly made any offers or sales of any
security or solicited any offers to buy any security under circumstances that
would require registration of the Securities being offered hereby under the
Securities Act or cause this offering of Securities to be integrated with any
prior offering of securities of the Company for purposes of the Securities Act,
which result of such integration would require registration under the Securities
Act, or any applicable stockholder approval provisions.

         (y) No Brokers. The Company has taken no action that would give rise to
any claim by any person for brokerage commissions, finder's fees or similar
payments by the Purchaser relating to this Agreement or the transactions
contemplated hereby.

         (z) Acknowledgment Regarding Securities. The number of Conversion
Shares issuable upon conversion of the Notes and the number of Warrant Shares
issuable upon exercise of the Warrants may increase in certain circumstances.
The Company's directors and executive officers have studied and fully understand
the nature of the Securities being sold hereunder. The Company acknowledges that
its obligation to issue Conversion Shares upon conversion of the Notes in
accordance with the terms thereof and the Warrant Shares upon the exercise of
the Warrants in accordance with the terms thereof is absolute and unconditional,
regardless of the dilution that such issuance may have on the ownership
interests of other stockholders and the availability of remedies provided for in
any of the Transaction Documents relating to a failure or refusal to issue
Conversion Shares or Warrant Shares. Taking the foregoing into account, the
Company's Board of Directors has determined in its good faith business judgment
that the issuance of the Units hereunder and the consummation of the other
transactions contemplated hereby are in the best interests of the Company and
its stockholders.

         (aa) Disclosure. All information relating to or concerning the Company
and/or any of its Subsidiaries set forth in this Agreement or provided to the
Purchaser pursuant to Section 2(d) hereof or otherwise in connection with the
transactions contemplated hereby is true and correct in all material respects
and the Company has not omitted to state any material fact necessary in order to
make the statements made herein or therein, in light of the circumstances under
which they were made, not misleading. No event or circumstance has occurred or
exists with respect to the Company or its Subsidiaries or their respective
businesses, properties, prospects, operations or financial conditions, which has
not been publicly disclosed but, under applicable law, rule or regulation, would
be required to be disclosed by the Company in a registration statement filed on
the date hereof by the Company under the Securities Act with respect to a
primary issuance of the Company's securities.

4.       COVENANTS.

         (a) Best Efforts. The parties shall use their respective best efforts
timely to satisfy each of the conditions described in Sections 6 and 7 of this
Agreement.

         (b) Form D; Blue Sky Laws. The Company shall file with the SEC a Form D
with respect to the Securities as required under Regulation D and provide a copy
thereof to the Purchaser promptly after such filing. The Company shall, on or
before the Closing Date, take such action as the Company shall reasonably
determine is necessary to qualify the Securities for sale to the Purchaser
pursuant to this Agreement under applicable securities or "blue sky" laws of the
states of the United States or obtain exemption therefrom, and shall provide
evidence of any such action so taken to the Purchaser on or prior to the Closing
Date. Within two days after the Closing Date, the Company shall file a Form 8-K
with the SEC concerning this Agreement and the transactions contemplated hereby,
which Form 8-K shall attach this Agreement and its Exhibits as exhibits to such
Form 8-K (the "8-K FILING"). From and after the 8-K Filing, the Company hereby
acknowledges that no Purchaser shall be in possession of any material nonpublic
information received from the Company, any of its Subsidiaries or any of its
respective officers, directors,

                                       9
<PAGE>

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 the
Purchaser with any material nonpublic information regarding the Company or any
of its Subsidiaries from and after the 8-K Filing without the express written
consent of such Purchaser; provided, however, that if the Purchaser exercises
its rights under Section 4(m) hereof it shall be deemed to have given such
express written consent. 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 other Transaction Documents, the Purchaser 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 Purchaser shall have any liability to the
Company, its Subsidiaries or any of its or their respective officers, directors,
employees, shareholders or agents for any such disclosure. Subject to the
foregoing, neither the Company nor the Purchaser 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 the Purchaser, 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) the Purchaser shall be
consulted by the Company in connection with any such press release or other
public disclosure prior to its release).

         (c) Reporting Status. So long as any Purchaser (or any of its
respective affiliates) beneficially owns any of the Securities, the Company
shall timely file all reports required to be filed with the SEC pursuant to the
Exchange Act, and the Company shall not terminate its status as an issuer
required to file reports under the Exchange Act even if the Exchange Act or the
rules and regulations thereunder would permit such termination. In addition, the
Company shall take all actions necessary to meet the "registrant eligibility"
requirements set forth in the general instructions to Form S-3 or any successor
form thereto, to continue to be eligible to register the resale of its Common
Stock on a registration statement on Form S-3 under the Securities Act.

         (d) Participation Right. Subject to the terms and conditions specified
in this Section 4(d), for a period beginning 180 days from the date hereof and
ending the day following the second anniversary of the date hereof, the
Purchaser shall have a right to participate in any issuance by the Company of
(i) equity or equity-linked securities, or (ii) debt which is convertible into
equity or in which there is an equity component ("ADDITIONAL SECURITIES") on the
same terms and conditions as offered by the Company to the other purchasers of
such Additional Securities. Each time the Company proposes to offer any
Additional Securities, the Company shall make an offering of such Additional
Securities to the Purchaser in accordance with the following provisions:

                  (i) The Company shall deliver a notice (the "NOTICE") to the
Purchaser, at least ten business days prior to the date on which it proposes to
offer such Additional Securities, stating (A) its bona fide intention to offer
such Additional Securities, (B) the number of such Additional Securities to be
offered, (C) the price and terms, if any, upon which it proposes to offer such
Additional Securities, and (D) the anticipated closing date of the sale of such
Additional Securities.

                  (ii) The Purchaser shall have the right, exercisable by
delivering written notice to such effect to the Company within five business
days after the Purchaser's receipt of the Notice, to purchase, at the price and
on the terms specified in the Notice, up to that portion of such Additional
Securities which equals the proportion that the number of Conversion Shares and
Warrant Shares that such Purchaser then owns or has the right to acquire (upon
conversion of the Notes and exercise of the Warrants) bears to the total number
of shares of Common Stock then outstanding (assuming full conversion, exercise
or exchange of all convertible, exercisable or exchangeable securities then
outstanding).

                  (iii) If all Additional Securities which the Purchaser is
entitled to purchase pursuant to this Section 4(d) are not purchased as provided
herein, the Company may, during the 75-day period following the expiration of
the 5 business day period (and, if necessary, such additional 5-day period)
provided in clause (ii), offer the remaining unsubscribed portion of such
Additional Securities to any person at a price not less than, and upon terms no
more favorable to the offeree than, as specified in the Notice. If the Company
does not consummate the sale of such Additional Securities within such period,
the right provided hereunder shall be deemed to be revived and such Additional
Securities shall not be offered or sold unless first reoffered to the Purchaser
in accordance herewith.

                                       10
<PAGE>

                  (iv) Notwithstanding the foregoing, the participation rights
granted in this Section 4(d) shall not be applicable to: (A) the issuance of
shares of Common Stock upon the exercise or conversion of the Company's options,
warrants or convertible securities outstanding as of the date hereof and
disclosed in Section 3(c) of the Disclosure Schedule in accordance with the
terms of such options, warrants or other securities as in effect on the date
hereof; (B) the grant of options to purchase Common Stock, with exercise prices
not less than the market price of the Common Stock on the date of grant, or the
grant of restricted shares of Common Stock, in each case which are issued to
employees, officers, directors or consultants of the Company for the primary
purpose of soliciting or retaining their employment or service pursuant to an
equity compensation plan approved by the Company's Board of Directors, and the
issuance of shares of Common Stock upon the exercise of any such options; (C)
the issuance of securities pursuant to a bona fide underwritten public offering;
(D) the issuance of the Notes and the Warrants pursuant hereto, the Conversion
Shares upon conversion of the Notes and the Warrant Shares upon exercise of the
Warrants; (E) the issuance of securities in a bona fide business acquisition;
(F) the issuance of securities in connection with a strategic business
partnership with an oil and gas company, the primary purpose of which, in the
reasonable judgment of the Company's Board of Directors, is not to raise
additional capital; or (G) the issuance of securities in a financing transaction
which, in the written opinion of counsel to the Company based upon published
Nasdaq Staff Interpretations, would require shareholder approval under Nasdaq
Marketplace Rule 4350(i)(1)(D)(ii) if the participation rights granted in this
Section 4(d) were otherwise available to and exercised by the Purchaser.

         (e) Use of Proceeds. The Company shall use the proceeds from the sale
and issuance of the Units for general corporate purposes and working capital.
Such proceeds shall not be used to (i) pay dividends; (ii) pay for any increase
in executive compensation or make any loan or other advance to any officer,
employee, shareholder, director or other affiliate of the Company, without the
express approval of the Board of Directors acting in accordance with past
practice; (iii) purchase debt or equity securities of any entity (including
redeeming the Company's own securities), except for (A) evidences of
indebtedness issued or fully guaranteed by the United States of America and
having a maturity of not more than one year from the date of acquisition, (B)
certificates of deposit, notes, acceptances and repurchase agreements having a
maturity of not more than one year from the date of acquisition issued by a bank
organized in the United States having capital, surplus and undivided profits of
at least $500,000,000, (C) the highest-rated commercial paper having a maturity
of not more than one year from the date of acquisition, and (D) "Money Market"
fund shares, or money market accounts fully insured by the Federal Deposit
Insurance Corporation and sponsored by banks and other financial institutions,
provided that the investments consist principally of the types of investments
described in clauses (A), (B), or (C) above; or (iv) make any investment not
directly related to the current business of the Company.

         (f) Financial Information. So long as the Purchaser (or any of its
respective affiliates) beneficially owns any Securities, the Company shall send
(via electronic transmission or otherwise) the following reports to such
Purchaser: (i) within ten days after the filing with the SEC, a copy of its
Annual Report on Form 10-K, its Quarterly Reports on Form 10-Q, its proxy
statements and any Current Reports on Form 8-K; and (ii) within one day after
release, copies of all press releases issued by the Company or any of its
Subsidiaries.

         (g) Reservation of Shares. The Company currently has authorized and
reserved for the purpose of issuance 2,000,000 shares of Common Stock to provide
for the full conversion of the Notes and issuance of the Conversion Shares in
connection therewith, the full exercise of the Warrants and the issuance of the
Warrant Shares in connection therewith and as otherwise required by the Notes,
the Warrants and the Registration Rights Agreement (collectively, the "ISSUANCE
OBLIGATIONS"). In the event such number of shares becomes insufficient to
satisfy the Issuance Obligations, the Company shall take all necessary action to
authorize and reserve such additional shares of Common Stock necessary to
satisfy the Issuance Obligations.

         (h) Listing. So long as the Purchaser (or any of its respective
affiliates) beneficially owns any Securities, the Company shall maintain the
listing of all Conversion Shares and Warrant Shares from time to time issuable
upon conversion of the Notes and exercise of the Warrants on each national
securities exchange, automated quotation system or electronic bulletin board on
which shares of Common Stock are currently listed. The Company shall use its
best efforts to continue the listing and trading of its Common Stock on the
SmallCap Market or on the Nasdaq National Market (the "NATIONAL MARKET"), the
New York Stock Exchange (the "NYSE") or the American Stock Exchange (the "AMEX")
and shall comply in all respects with the reporting, filing and other
obligations under the bylaws or rules of the National Association of Securities
Dealers, Inc. (the "NASD"), such exchanges, or such electronic system, as
applicable. The Company shall promptly provide to the Purchaser copies of any
notices it

                                       11
<PAGE>

receives regarding the continued eligibility of the Common Stock for trading on
any securities exchange or automated quotation system on which securities of the
same class or series issued by the Company are then listed or quoted, if any.

         (i) Corporate Existence. So long as the Purchaser (or any of its
respective affiliates) beneficially owns any Securities, the Company shall
maintain its corporate existence, and in the event of a merger, consolidation or
sale of all or substantially all of the Company's assets, the Company shall
ensure that the surviving or successor entity in such transaction (i) assumes
the Company's obligations under this Agreement and the other Transaction
Documents and the agreements and instruments entered into in connection herewith
and therewith regardless of whether or not the Company would have had a
sufficient number of shares of Common Stock authorized and available for
issuance in order to effect the conversion of all the Notes and exercise in full
of all Warrants outstanding as of the date of such transaction and (ii) except
in the event of a merger, consolidation of the Company into any other
corporation, or the sale or conveyance of all or substantially all of the assets
of the Company where the consideration consists solely of cash, the surviving or
successor entity is a publicly traded corporation whose common stock is listed
for trading on the SmallCap Market, the National Market, the NYSE or the AMEX.

         (j) No Integrated Offerings. The Company shall not make any offers or
sales of any security (other than the Securities) under circumstances that would
require registration of the Securities being offered or sold hereunder under the
Securities Act or cause this offering of the Securities to be integrated with
any other offering of securities by the Company for purposes of any stockholder
approval provision applicable to the Company or its securities.

         (k) Legal Compliance. The Company shall conduct its business and the
business of its Subsidiaries in compliance with all laws, ordinances or
regulations of governmental entities applicable to such businesses, except where
the failure to do so would not have a Material Adverse Effect.

         (l) Information. So long as the Purchaser (or any of its respective
affiliates) beneficially owns any Securities, the Company shall furnish to such
Purchaser:

                  (i) concurrently with the filing with the SEC of its annual
reports on Form 10-K, a certificate of the President, a Vice President or a
senior financial officer of the Company stating that, based upon such
examination or investigation and review of this Agreement as in the opinion of
the signer is necessary to enable the signer to express an informed opinion with
respect thereto, neither the Company nor any of its Subsidiaries is or has
during such period been in default in the performance or observance of any of
the terms, covenants or conditions hereof, or, if the Company or any of its
Subsidiaries shall be or shall have been in default, specifying all such
defaults, and the nature and period of existence thereof, and what action the
Company or such Subsidiary has taken, is taking or proposes to take with respect
thereto; and

                  (ii) the information the Company must deliver to any holder or
to any prospective transferee of Securities in order to permit the sale or other
transfer of such Securities pursuant to Rule 144A of the SEC or any similar rule
then in effect.

The Company shall keep at its principal executive office a true copy of this
Agreement (as at the time in effect), and cause the same to be available for
inspection at such office during normal business hours by any holder of
Securities or any prospective transferee of Securities designated by a holder
thereof.

         (m) Inspection of Properties and Books. So long as the Purchaser (or
any of its respective affiliates) beneficially owns any Securities, such
Purchaser and its representatives and agents (collectively, the "INSPECTORS")
shall have the right, at such Purchaser's expense, to visit and inspect any of
the properties of the Company and of its Subsidiaries, to examine the books of
account and records of the Company and of its Subsidiaries, to make or be
provided with copies and extracts therefrom, to discuss the affairs, finances
and accounts of the Company and of its Subsidiaries with, and to be advised as
to the same by, its and their officers, employees and independent public
accountants (and by this provision the Company authorizes such accountants to
discuss such affairs, finances and accounts, whether or not a representative of
the Company is present) all at such reasonable times and intervals and to such
reasonable extent as the Purchaser may desire; provided, however, that each
Inspector shall hold in confidence and shall not make any disclosure (except to
such Purchaser) of any such information which the

                                       12
<PAGE>

Company determines in good faith to be confidential, and of which determination
the Inspectors are so notified, unless (i) the disclosure of such information is
necessary to avoid or correct a misstatement or omission in any Registration
Statement filed pursuant to the Registration Rights Agreement, (ii) the release
of such information is ordered pursuant to a subpoena or other order from a
court or government body of competent jurisdiction, or (iii) such information
has been made generally available to the public other than by disclosure in
violation of this or any other agreement. The Purchaser agrees that it shall,
upon learning that disclosure of such information is sought in or by a court or
governmental body of competent jurisdiction or through other means, give prompt
notice to the Company and allow the Company, at its expense, to undertake
appropriate action to prevent disclosure of, or to obtain a protective order
for, the information deemed confidential.

         (n) Shareholders Rights Plan. No claim shall be made or enforced by the
Company or any other person that the Purchaser is an "Acquiring Person" under
any shareholders rights plan or similar plan or arrangement in effect or
hereafter adopted by the Company, or that the Purchaser could be deemed to
trigger the provisions of any such plan or arrangement, by virtue of receiving
Securities under this Agreement or any other Transaction Documents or under any
other agreement between the Company and the Purchaser.

         (o) Pledge of Securities. The Company acknowledges and agrees that the
Securities may be pledged by the Purchaser in connection with a bona fide margin
agreement or other loan or financing arrangement that is secured by the
Securities. The pledge of Securities shall not be deemed to be a transfer, sale
or assignment of the Securities hereunder, and no Purchaser 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. The Company shall 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 the Purchaser.

         (p) Variable Securities. So long as the Purchaser (or any of its
respective affiliates) beneficially owns any Securities, the Company shall not,
without first obtaining the written approval of the holders of a majority of the
aggregate principal face amount of the Notes then outstanding (which approval
may be given or withheld by such holders in their sole and absolute discretion),
issue or sell any rights, warrants or options to subscribe for or purchase
Common Stock, or any other securities directly or indirectly convertible into or
exchangeable or exercisable for Common Stock, at an effective conversion,
exchange or exercise price that 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.

         (q) Expenses. At the Closing, the Company shall pay to BayStar Capital
II, LP ("BAYSTAR") reimbursement for the out-of-pocket expenses reasonably
incurred by BayStar, its affiliates and its or their advisors in connection with
the negotiation, preparation, execution and delivery of this Agreement and the
other Transaction Documents and the consummation of the transactions
contemplated hereby and thereby, including, without limitation, BayStar's and
its affiliates' and advisors' reasonable due diligence and attorneys' fees and
expenses (the "EXPENSES"); provided, however, that the aggregate amount of the
Expenses payable to BayStar shall not exceed $25,000 (the "EXPENSE CAP") unless
prior approval is obtained from the Company. The Expenses shall be paid at the
Closing by delivery by the Company of a Company check or wire transfer to
BayStar of immediately available funds or, at the discretion of BayStar, by
deduction by BayStar of such balance of the Expenses from the Purchase Price
payable by BayStar hereunder. In addition, from time to time thereafter, upon

in each case to the extent reasonably incurred by BayStar, its affiliates or its
or their advisors in connection with the negotiation, preparation, execution and
delivery of this Agreement and the other Transaction Documents and the
consummation of the transactions contemplated hereby and thereby.

5.       SECURITIES TRANSFER MATTERS.

         (a) Conversion and Exercise. Upon conversion of the Notes or exercise
of the Warrants by any person, (i) if the DTC Transfer Conditions (as defined
below) are satisfied, the Company shall cause its transfer agent to
electronically transmit all Conversion Shares and Warrant Shares by crediting
the account of such person or its nominee with the Depository Trust Company
("DTC") through its Deposit Withdrawal Agent Commission system; or (ii) if the
DTC Transfer Conditions are not satisfied, the Company shall issue and deliver,
or instruct its transfer agent to issue and deliver, certificates (subject to
the legend and other applicable provisions hereof), registered in the name of
such person its nominee, physical certificates representing the Conversion
Shares and Warrant Shares, as applicable. Even if the DTC Transfer Conditions
are satisfied, any person effecting a conversion
5
<PAGE>

of Notes or exercising Warrants may instruct the Company to deliver to such
person or its nominee physical certificates representing the Conversion Shares
and Warrant Shares, as applicable, in lieu of delivering such shares by way of
DTC Transfer. For purposes of this Agreement, "DTC TRANSFER CONDITIONS" means
that (A) the Company's transfer agent is participating in the DTC Fast Automated
Securities Transfer program and (B) the certificates for the Conversion Shares
or Warrant Shares required to be delivered do not bear a legend and the person
effecting such conversion or exercise is not then required to return such
certificate for the placement of a legend thereon.

         (b) Transfer or Resale. The Purchaser understands that (i) except as
provided in the Registration Rights Agreement, the sale or resale of the
Securities have not been and are not being registered under the Securities Act
or any state securities laws, and the Securities may not be transferred unless
(A) the transfer is made pursuant to and as set forth in an effective
registration statement under the Securities Act covering the Securities; or (B)
such Purchaser shall have delivered to the Company an opinion of counsel (which
opinion shall be in form, substance and scope customary for opinions of counsel
in comparable transactions) to the effect that the Securities to be sold or
transferred may be sold or transferred pursuant to an exemption from such
registration; or (C) sold under and in compliance with Rule 144; or (D) sold or
transferred to an affiliate of such Purchaser that is an Accredited Investor and
agrees to sell or otherwise transfer the Securities only in accordance with the
provisions of this Section 5(b); and (ii) neither the Company nor any other
person is under any obligation to register such Securities under the Securities
Act or any state securities laws (other than pursuant to the terms of the
Registration Rights Agreement). Notwithstanding the foregoing or anything else
contained herein to the contrary, the Securities may be pledged as collateral in
connection with a bona fide margin account or other lending arrangement,
provided such pledge is consistent with applicable laws, rules and regulations.

         (c) Legends. The Purchaser understands that the Notes and the Warrants
and, until such time as the Conversion Shares and Warrant Shares have been
registered under the Securities Act (including registration pursuant to Rule 416
thereunder) as contemplated by the Registration Rights Agreement or otherwise
may be sold by such Purchaser under Rule 144, the certificates for the
Conversion Shares and Warrant Shares may bear a restrictive legend in
substantially the following form:

                  The securities represented by this certificate have not been
                  registered under the Securities Act of 1933, as amended, or
                  the securities laws of any state of the United States or in
                  any other jurisdiction. The securities represented hereby may
                  not be offered, sold or transferred in the absence of an
                  effective registration statement for the securities under
                  applicable securities laws unless offered, sold or transferred
                  pursuant to an available exemption from the registration
                  requirements of those laws.

         The Company shall, immediately prior to a registration statement
covering the Securities (including, without limitation, the Registration
Statement contemplated by the Registration Rights Agreement) being declared
effective, deliver to its transfer agent an opinion letter of counsel, opining
that at any time such registration statement is effective, the transfer agent
shall issue, in connection with the issuance of the Conversion Shares and
Warrant Shares, certificates representing such Conversion Shares and Warrant
Shares without the restrictive legend above, provided such Conversion Shares and
Warrant Shares are to be sold pursuant to the prospectus contained in such
registration statement. Upon receipt of such opinion, the Company shall cause
the transfer agent to confirm, for the benefit of the holders, that no further
opinion of counsel is required at the time of transfer in order to issue such
shares without such restrictive legend.

         The legend set forth above shall be removed and the Company shall issue
a certificate without such legend to the holder of any Security upon which it is
stamped, if, unless otherwise required by state securities laws, (i) the sale of
such Security is registered under the Securities Act (including registration
pursuant to Rule 416 thereunder); (ii) such holder provides the Company with an
opinion of counsel, in form, substance and scope customary for opinions of
counsel in comparable transactions, to the effect that a public sale or transfer
of such Security may be made without registration under the Securities Act; or
(iii) such holder provides the Company with reasonable assurances that such
Security can be sold under Rule 144. In the event the above legend is removed
from any Security and thereafter the effectiveness of a registration statement
covering such Security is suspended or the Company determines that a supplement
or amendment thereto is required by applicable securities laws, then upon
reasonable advance written notice to the Purchaser the Company may require that
the above legend be placed on any

                                       14
<PAGE>

such Security that cannot then be sold pursuant to an effective registration
statement or under Rule 144 and the Purchaser shall cooperate in the replacement
of such legend. Such legend shall thereafter be removed when such Security may
again be sold pursuant to an effective registration statement or under Rule 144.

         (d) Transfer Agent Instructions. Upon compliance by the Purchaser with
the provisions of this Section 5 with respect to the transfer of any Securities,
the Company shall permit the transfer of such Securities and, in the case of the
transfer of Conversion Shares or Warrant Shares, promptly instruct its transfer
agent to issue one or more certificates (or effect a DTC Transfer) in such name
and in such denominations as specified by such Purchaser. The Company shall not
give any instructions to its transfer agent with respect to the Securities,
other than any permissible or required instructions provided in this Section 5,
and the Securities shall otherwise be freely transferable on the books and
records of the Company as and to the extent provided in this Agreement.

<PAGE>

         (h) Third Party Beneficiaries. This Agreement is intended for the
benefit of the parties hereto and their respective permitted successors and

by, any other person.

         (i) Survival. The representations and warranties of the Company and the
agreements and covenants set forth in Sections 3, 4, 5 and 8 hereof shall
survive the Closing notwithstanding any due diligence investigation conducted by
or on behalf of the Purchaser. Moreover, none of the representations and
warranties made by the Company herein shall act as a waiver of any rights or
remedies the Purchaser may have under applicable U.S. federal or state
securities laws.

         (j) Publicity. The Company and the Purchaser shall have the right to
approve before issuance any press releases, SEC or, to the extent applicable,
NASD filings, 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 the Purchaser, to make any press release or SEC
or, to the extent applicable, NASD filings with respect to such transactions as
is required by applicable law and regulations (although the Purchaser shall be
consulted by the Company in connection with any such press release and filing
prior to its release and shall be provided with a copy thereof and must provide
specific consent to the use of their name in connection therewith).

         (k) 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
the 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.

         (l) Indemnification. In consideration of the Purchaser's execution and
delivery of this Agreement and the other Transaction Documents and purchase of
the Securities hereunder, and in addition to all of the Company's other
obligations under this Agreement and the other Transaction Documents, from and
after the Closing, the Company shall defend, protect, indemnify and hold
harmless the Purchaser 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 (i)
any misrepresentation or breach of any representation or warranty made by the
Company in this Agreement, any other Transaction Document or any other
certificate, instrument or document contemplated hereby or thereby, (ii) any
breach of any covenant, agreement or obligation of the Company contained in this
Agreement, any other Transaction Document or any other certificate, instrument
or document contemplated hereby or thereby or (iii) 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 (A) the execution, delivery, performance or enforcement
of this Agreement, any other Transaction Document or any other certificate,
instrument or document contemplated hereby or thereby, (B) any transaction
financed or to be financed in whole or in part, directly or indirectly, with the
proceeds of the issuance and sale of the Securities, (C) any disclosure made by
the Purchaser pursuant to Section 4(b) or 4(m) hereof, or (D) the status of the
Purchaser or holder of the Securities as an investor in the Company. 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 8(l)
shall be the same as those set forth in Section 6(c) of the Registration Rights
Agreement.

         (m) Payment Set Aside. To the extent that the Company makes a payment
or payments to the Purchaser hereunder or pursuant to any of the other
Transaction Documents or the Purchaser enforces or exercises its 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, 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

                                       18
<PAGE>

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.

         (n) Joint Participation in Drafting. Each party to this Agreement has
participated in the negotiation and drafting of this Agreement and the other
Transaction Documents. As such, the language used herein and therein shall be
deemed to be the language chosen by the parties hereto to express their mutual
intent, and no rule of strict construction will be applied against any party to
this Agreement.

         (o) Remedies. No provision of this Agreement or any other Transaction
Document providing for any remedy to the Purchaser shall limit any other remedy
which would otherwise be available to such Purchaser at law, in equity or
otherwise. Nothing in this Agreement or any other Transaction Document shall
limit any rights the Purchaser may have under any applicable federal or state
securities laws with respect to the investment contemplated hereby. The Company
acknowledges that a breach by it of its obligations hereunder will cause
irreparable harm to the Purchaser by vitiating the intent and purpose of the
transactions contemplated hereby. Accordingly, the Company acknowledges that the
remedy at law for a breach of its obligations hereunder (including, but not
limited to, its obligations pursuant to Section 5 hereof) will be inadequate and
agrees, in the event of a breach or threatened breach by the Company of the
provisions of this Agreement (including, but not limited to, its obligations
pursuant to Section 5 hereof), that the Purchaser shall be entitled, in addition
to all other available remedies, to an injunction restraining any breach and
requiring immediate issuance and transfer of the Securities, without the
necessity of showing economic loss and without any bond or other security being
required.

         (p) Knowledge. As used in this Agreement, the term "knowledge" of any
person or entity shall mean and include (i) actual knowledge and (ii) that
knowledge which a reasonably prudent business person could have obtained in the
management of his or her business affairs after making due inquiry and
exercising due diligence which a prudent business person should have made or
exercised, as applicable, with respect thereto.

or if later amended or supplemented, then as so amended or supplemented. This
Note is being issued by the Borrower pursuant to that certain Securities
Purchase Agreement, dated as of the date hereof, between the Borrower and the
signatory thereto (the "SECURITIES PURCHASE AGREEMENT"). The Note, the
Securities Purchase Agreement, the Warrants issued pursuant to the Securities
Purchase Agreement (the "WARRANTS") and the Registration Rights Agreement, dated
as of the date hereof, between the Borrower and the initial Holder of the Notes
(the "REGISTRATION RIGHTS AGREEMENT") are collectively referred to herein as the
"TRANSACTION DOCUMENTS." All capitalized terms used but not otherwise defined
herein shall have the respective meanings assigned to such terms in the
Securities Purchase Agreement.

                                    ARTICLE I
                        PAYMENT OF PRINCIPAL AND INTEREST

         A. Payment of Interest. Interest shall accrue on the unpaid principal
balance hereof from the Issuance Date until the same is paid, whether at
maturity, or upon prepayment, repayment, conversion or otherwise. Interest shall
be calculated based on a 365 day year and shall be payable quarterly in arrears
on March 31, June 30, September 30, and December 31 of each year (each, an
"INTEREST PAYMENT DATE"), commencing on December 31, 2004. Payment of each
installment of interest due hereunder shall be made in cash.

         B. Payment of Principal. The principal amount hereof, together with all
accrued and unpaid interest thereon, shall be due and payable on the Scheduled
Maturity Date. Payment of principal and accrued interest on the Scheduled
Maturity Date shall be made, at the Borrower's election but subject to the
Payment Limitations and the limitations set forth in Article VIII, (i) in cash,
(ii) in such number of duly authorized, validly issued, fully paid and
non-assessable shares of Common Stock determined by dividing the aggregate
amount due on the Scheduled Maturity Date by the lesser of (a) the Closing Sales
Price of the Common Stock on the Scheduled Maturity Date or (b) 90% of the
average Closing Sales Price of the Common Stock over the 20 trading day period
ending on the day immediately prior to the Scheduled Maturity Date, or (iii) in
any combination of cash and shares of Common Stock with an aggregate value equal
to the principal and interest then due. In the event that the Borrower is
prohibited from issuing shares of Common Stock in connection with the payment
pursuant to this Paragraph B as a result of the

<PAGE>

operation of the Payment Limitations or the limitations set forth in Article
VIII, the Borrower shall be required to pay in cash any amounts due hereunder as
to which it is so prohibited.

         C. Prepayment. Except as and to the extent otherwise provided herein,
no amounts of principal or interest due hereunder may be prepaid by the Borrower
without the prior written consent of the Holder.

         D. Manner of Payments. Subject to the Payment Limitations, in the event
that the Borrower elects to repay this Note on the Scheduled Maturity Date in
shares of Common Stock, the Borrower shall give written notice to the Holder at
least five business days in advance of the Scheduled Maturity Date. All cash
payments of principal and interest shall be made in, and all references herein
to monetary denominations shall refer to, lawful money of the United States of
America. All payments shall be made at such address as the Holder shall have
given or shall hereafter give to the Borrower by written notice made in
accordance with the provisions of this Note. If any cash payment to be made
hereunder shall be due on a day other than a business day, such payment shall be
made on the next succeeding business day and such extension of time shall be
included in computing interest in connection with such payment. If any payment
due hereunder is not made when due, the Holder shall thereafter be entitled to
interest on the unpaid amount at a per annum rate equal to the lower of eighteen
percent (18%) and the highest interest rate permitted by applicable law until
such amount is paid in full.

         E. Payment Limitations. Notwithstanding any other provision of this
Article I, (i) on the Scheduled Maturity Date, the Borrower shall be required to
make the same election as to payment method for this Note as it makes for all
other Notes then outstanding; (ii) in no event shall the Borrower repay this
Note on the Scheduled Maturity Date in shares of Common Stock to the extent that
such number of shares of Common Stock, when added to the aggregate number of
shares of Common Stock previously issued upon conversions of the Notes or
previously issued or issuable upon exercise of the Warrants, would exceed an
aggregate of 3,000,487 shares of Common Stock; and (iii) in order to repay this
Note on the Scheduled Maturity Date in shares of Common Stock, the shares of
Common Stock to be issued on the Scheduled Maturity Date, must be registered
under the Securities Act for resale by the holders and listed or traded on any
of the New York Stock Exchange, the American Stock Exchange, the Nasdaq National
Market or the Nasdaq SmallCap Market (or the successor to any of them) (the
limitations set forth in clauses (i), (ii), (iii), (iv) and (v) being referred
to herein as the "PAYMENT LIMITATIONS").

                                   ARTICLE II
                                   CONVERSION

         A. Conversion at the Option of the Holder. Subject to the limitations
on conversions contained in Article VIII, the Holder may, at any time and from
time to time, convert (an "OPTIONAL CONVERSION") all or any portion of the
unpaid principal amount hereof and any accrued interest thereon into a number of
fully paid and non-assessable shares of Common Stock as is equal to the quotient
obtained by dividing (x) the amount of principal and interest being so converted
by (y) the Conversion Price then in effect.

         B. Mechanics of Conversion. In order to effect an Optional Conversion,
the Holder shall: (x) fax (or otherwise deliver) a copy of the fully executed
Notice of Conversion to the Borrower (Attention: Secretary) and (y) surrender or
cause to be surrendered this Note, duly endorsed, along with a copy of the
Notice of Conversion as soon as practicable thereafter to the Borrower. Upon
receipt by the Borrower of a facsimile copy of a Notice of Conversion from the
Holder, the Borrower shall promptly send, via facsimile, a confirmation to the
Holder stating that the Notice of Conversion has been received, the date upon
which the Borrower expects to deliver the Common Stock issuable upon such
conversion and the name and telephone number of a contact person at the Borrower
regarding the conversion. The Borrower shall not be obligated to issue shares of
Common Stock upon a conversion unless this Note is delivered to the Borrower as
provided above, or the Holder notifies the Borrower that this Note has been
lost, stolen or destroyed and delivers the documentation to the Borrower
required by Article X.B hereof.

                  (i) Delivery of Common Stock Upon Conversion. Upon the
surrender of this Note accompanied by a Notice of Conversion, the Borrower
(itself, or through its transfer agent) shall, no later than the later of (a)
the second business day following the Conversion Date and (b) the business day
following the date of such surrender (or, in the case of lost, stolen or
destroyed certificates, after provision of indemnity pursuant to Article X.B)
(the "DELIVERY PERIOD"), issue and deliver (i.e., deposit with a nationally
recognized overnight courier

                                       2
<PAGE>
service postage prepaid) to the Holder or its nominee (x) that number of shares
of Common Stock issuable upon conversion of that portion of this Note being
converted and (y) a new Note representing the principal balance of this Note not
being converted, if any. Notwithstanding the foregoing, if the Borrower's
transfer agent is participating in the Depository Trust Company ("DTC") Fast
Automated Securities Transfer program, and so long as the certificates therefor
do not bear a legend (pursuant to the terms of the Securities Purchase
Agreement) and the holder thereof is not then required to return such
certificate for the placement of a legend thereon (pursuant to the terms of the
Securities Purchase Agreement), the Borrower shall cause its transfer agent to
promptly electronically transmit the Common Stock issuable upon conversion to
the Holder by crediting the account of the Holder or its nominee with DTC
through its Deposit Withdrawal Agent Commission system ("DTC TRANSFER"). If the
aforementioned conditions to a DTC Transfer are not satisfied, the Borrower
shall deliver as provided above to the Holder physical certificates representing
the Common Stock issuable upon conversion. Further, the Holder may instruct the
Borrower to deliver to the Holder physical certificates representing the Common
Stock issuable upon conversion in lieu of delivering such shares by way of DTC
Transfer.

                  (ii) Taxes. The Borrower shall pay any and all taxes that may
be imposed upon it with respect to the issuance and delivery of the shares of
Common Stock upon the conversion of this Note.

                  (iii) No Fractional Shares. If any conversion of this Note
would result in the issuance of a fractional share of Common Stock (aggregating
the entire amount of principal and interest being converted pursuant to a given
Notice of Conversion), such fractional share shall be payable in cash based upon
the Closing Sales Price of the Common Stock at such time, and the number of
shares of Common Stock issuable upon conversion of this Note shall be the next
lower whole number of shares. If the Borrower elects not to, or is unable to,
make such a cash payment, the holder shall be entitled to receive, in lieu of
the final fraction of a share, one whole share of Common Stock.

                  (iv) Conversion Disputes. In the case of any dispute with
respect to a conversion, the Borrower shall promptly issue such number of shares
of Common Stock as are not disputed in accordance with subparagraph (i) above.
If such dispute involves the calculation of the Conversion Price, and such
dispute is not promptly resolved by discussion between the Holders and the
Borrower, the Borrower shall submit the disputed calculations to an independent
outside accountant (which accountant shall be subject to the reasonable approval
of the Majority Holders) via facsimile within three business days of receipt of
the Notice of Conversion. The accountant shall promptly audit the calculations
and notify the Borrower and the Holders of the results no later than three
business days from the date it receives the disputed calculations. The
accountant's calculation shall be deemed conclusive, absent manifest error, and
the party whose proposed calculation is further from the calculation determined
by the accountant shall bear all of the accountant's expenses (which, if the
disputing Holders are the non-prevailing party, shall be allocated pro rata
among such disputing Holders). The Borrower shall then issue the appropriate
number of shares of Common Stock in accordance with subparagraph (i) above.

                  (v) Payment of Accrued Amounts. Upon conversion of any unpaid
principal amount of this Note, all accrued interest on such amount through and
including the Conversion Date shall be paid on the Conversion Date in accordance
with one of the permitted payment methods set forth in Article I.A above.

         C. Mandatory Conversion into Common Stock. Subject to the limitations
on conversion contained in Article VIII, if at any time following the second
anniversary of the Issuance Date all of the Required Conditions are satisfied,
then, at the option of the Borrower exercisable by the delivery of written
notice to the Holders, delivered no more than ten days and no less than three
days prior to the Conversion Date stated in such notice, convert all, but not
less than all, of the Notes into a number of fully paid and non-assessable
shares of Common Stock determined in accordance with the formula set forth in
Paragraph A of this Article II (a "MANDATORY CONVERSION"). Thereafter, the
Borrower and the Holder shall follow the applicable conversion procedures set
forth in Article II.B (including the requirement that the Holder deliver the
Notes being converted to the Borrower); provided, however, the Holder shall not
be required to deliver a Notice of Conversion to the Borrower in order for the
Borrower to effect a Mandatory Conversion. In the event that the Borrower is
prohibited from issuing shares of Common Stock upon a Mandatory Conversion
pursuant to this Article II.C as a result of the operation of the limitations
set forth in Article VIII, the Borrower shall pay to each Holder an amount of
cash equal to the Closing Sales Price of the Common

                                       3
<PAGE>

Stock on the Conversion Date multiplied by the number of shares of Common Stock
that the Borrower is prohibited from issuing to such Holder as a result of the
operation of the limitations set forth in Article VIII.

                                   ARTICLE III
                      RESERVATION OF SHARES OF COMMON STOCK

         A. Reserved Amount. On or prior to the Issuance Date, the Borrower
shall reserve 2,000,000 shares of its authorized but unissued shares of Common
Stock for issuance upon conversion of the Notes pursuant to Article II, and,
thereafter, the number of authorized but unissued shares of Common Stock so
reserved (the "RESERVED AMOUNT") shall at all times be sufficient to provide for
the full conversion of all of the Notes outstanding at the then current
Conversion Price thereof (without giving effect to the limitations contained in
Article VIII). The Reserved Amount shall be allocated among the Holders as
provided in Article X.C.

         B. Increases to Reserved Amount. If the Reserved Amount for any three
consecutive trading days (the last of such three trading days being the
"AUTHORIZATION TRIGGER DATE") shall be less than one hundred percent (100%) of
the number of shares of Common Stock issuable upon full conversion of all then
outstanding Notes (without giving effect to the limitations contained in Article
VIII), the Borrower shall immediately notify the Holders of such occurrence and
shall take immediate action (including, if necessary, seeking stockholder
approval to authorize the issuance of additional shares of Common Stock) to
increase the Reserved Amount to one hundred percent (100%) of the number of
shares of Common Stock then issuable upon full conversion of all then
outstanding Notes at the then current Conversion Price (without giving effect to
the limitations contained in Article VIII). In the event the Borrower fails to
so increase the Reserved Amount within 90 days after an Authorization Trigger
Date, the Holder shall thereafter have the option, exercisable in whole or in
part at any time and from time to time, by delivery of a Default Notice to the
Borrower, to require the Borrower to prepay in cash, for an amount equal to the
Default Amount (as defined in Article V.B), that portion of the unpaid principal
amount hereof and accrued interest thereon such that, after giving effect to
such prepayment, the then unissued portion of the Holder's Reserved Amount is at
least equal to one hundred percent (100%) of the total number of shares of
Common Stock issuable upon conversion of this Note by the Holder. If the
Borrower fails to prepay any portion of this Note as required hereby within five
business days after its receipt of such Default Notice, then the Holder shall be
entitled to the remedies provided in Article V.C.

                                   ARTICLE IV
                         FAILURE TO SATISFY CONVERSIONS

         A. Conversion Defaults. If, at any time, (i) the Holder submits a
Notice of Conversion and the Borrower fails for any reason (other than because
such issuance would exceed the Holder's allocated portion of the Reserved
Amount, for which failures the holders shall have the remedies set forth in
Article III) to deliver, on or prior to the fifth business day following the
expiration of the Delivery Period for such conversion, such number of freely
tradable shares of Common Stock to which the Holder is entitled upon such
conversion, or (ii) the Borrower provides written notice to the Holders (or
makes a public announcement via press release) at any time of its intention not
to issue freely tradable shares of Common Stock upon exercise by the Holders of
their conversion rights in accordance with the terms of the Notes (other than
because such issuance would exceed a Holder's allocated portion of the Reserved
Amount) (each of (i) and (ii) being a "CONVERSION DEFAULT"), then the Holder may
elect, at any time and from time to time prior to the Default Cure Date for such
Conversion Default, by delivery of a Default Notice to the Borrower, to have all
or any portion of the unpaid principal amount hereof and accrued interest
thereto prepaid by the Borrower in cash, for an amount per share equal to the
Default Amount (as defined in Article V.B). If the Borrower fails to prepay any
portion of this Note as required hereby within five business days after its
receipt of such Default Notice, then the Holder shall be entitled to the
remedies provided in Article V.C.

         B. Buy-In Cure. Unless the Borrower has notified the Holder in writing
prior to the delivery by the Holder of a Notice of Conversion that the Borrower
is unable to honor conversions, if (i) (a) the Borrower fails to promptly
deliver during the Delivery Period shares of Common Stock to the Holder upon a
conversion of all or any portion of this Note or (b) there shall occur a Legend
Removal Failure (as defined in Article V.A(iv) below) and (ii) thereafter, the
Holder purchases (in an open market transaction or otherwise) shares of Common
Stock to make delivery in satisfaction of a sale by the Holder of the unlegended
shares of Common Stock (the "SOLD SHARES")

                                       4
<PAGE>

which the Holder anticipated receiving upon such conversion (a "BUY-IN"), the
Borrower shall pay the Holder, in addition to any other remedies available to
the Holder, the amount by which (x) the Holder's total purchase price (including
brokerage commissions, if any) for the unlegended shares of Common Stock so
purchased exceeds (y) the net proceeds received by the Holder from the sale of
the Sold Shares. For example, if the Holder purchases unlegended shares of
Common Stock having a total purchase price of $11,000 to cover a Buy-In with
respect to shares of Common Stock it sold for $10,000, the Borrower will be
required to pay the Holder $1,000. The Holder shall provide the Borrower written
notification and supporting documentation indicating any amounts payable to the
Holder pursuant to this Article IV.B.

                                    ARTICLE V
                                EVENTS OF DEFAULT

         A. Events of Default. In the event (each of the events described in
clauses (i)-(ix) below after expiration of the applicable cure period (if any)
being an "EVENT OF DEFAULT"):

                  (i) the Borrower fails to pay in full an interest payment
within ten days after a scheduled Interest Payment Date, or fails to pay in full
the principal hereof, and/or the accrued and unpaid interest thereon, when due,
whether at maturity, upon acceleration or otherwise;

                  (ii) the Common Stock (including any of the shares of Common
Stock issuable upon conversion of this Note) is suspended from trading on any
of, or is not listed (and authorized) for trading on at least one of, the New
York Stock Exchange, the American Stock Exchange, the Nasdaq National Market or
the Nasdaq SmallCap Market for an aggregate of ten or more trading days in any
twelve month period;

                  (iii) the registration statement required to be filed by the
Borrower pursuant to Section 2(a) of the Registration Rights Agreement has not
been declared effective by the two hundred seventieth (270th) day following the
Issuance Date or such registration statement, after being declared effective,
cannot be utilized by the Holders for the resale of all of their Registrable
Securities (as defined in the Registration Rights Agreement) for an aggregate of
more than 60 days;

                  (iv) the Borrower fails to remove any restrictive legend on
any certificate or any shares of Common Stock issued to the Holder upon
conversion of this Note as and when required by the terms hereof and of the
Securities Purchase Agreement or the Registration Rights Agreement (a "LEGEND
REMOVAL FAILURE"), and any such failure continues uncured for ten business days
after the Borrower has been notified thereof in writing by the Holder;

                  (v) the Borrower provides written notice (or otherwise
indicates) to the Holder, or states by way of public announcement distributed
via a press release, at any time, of its intention not to issue, or otherwise
refuses to issue, shares of Common Stock to the Holder upon conversion in
accordance with the terms of this Note (other than because such issuance would
exceed the Holder's allocated portion of the Reserved Amount, for which failures
the Holder shall have the remedies set forth in Article III);

                  (vi) the Borrower or any subsidiary of the Borrower shall make
an assignment for the benefit of creditors, or apply for or consent to the
appointment of a receiver or trustee for it or for a substantial part of its
property or business, or such a receiver or trustee shall otherwise be
appointed;

                  (vii) bankruptcy, insolvency, reorganization or liquidation
proceedings or other proceedings for the relief of debtors shall be instituted
by or against the Borrower or any subsidiary of the Borrower and if instituted
against the Borrower or any subsidiary of the Borrower by a third party, shall
not be dismissed within 60 days of their initiation;

                  (viii)   the Borrower shall:

                           (a) sell, convey or dispose of all or substantially
all of its assets (the presentation of any such transaction for stockholder
approval being conclusive evidence that such transaction involves the sale of
all

                                       5
<PAGE>

or substantially all of the assets of the Borrower), unless the Holder has
approved such transaction pursuant to Article VII.B below;

                           (b) merge or consolidate with or into any person or
entity, which results in either (i) the holders of the voting securities of the
Borrower immediately prior to such transaction holding or having the right to
direct the voting of fifty percent (50%) or less of the total outstanding voting
securities of the Borrower or such other surviving or acquiring person or entity
immediately following such transaction or (ii) the members of the board of
directors or other governing body of the Borrower comprising fifty percent (50%)
or less of the members of the board of directors or other governing body of the
Borrower or such other surviving or acquiring person or entity immediately
following such transaction, unless the Holder has approved such transaction
pursuant to Article VII.B below;

                           (c) either (i) fail to pay, when due, or within any
applicable grace period, any payment with respect to any indebtedness of the
Borrower in excess of $250,000 due to any third party, other than payments
contested by the Borrower in good faith, or otherwise be in breach or violation
of any agreement for monies owed or owing in an amount in excess of $250,000
which breach or violation permits the other party thereto to declare a default
or otherwise accelerate amounts due thereunder, or (ii) suffer to exist any
other default or event of default under any agreement binding the Borrower which
default or event of default would or is likely to have a material adverse effect
on the business, operations, properties, prospects or financial condition of the
Borrower;

                           (d) have thirty-five percent (35%) or more of the
voting power of its capital stock owned beneficially by one person, entity or
"group" (as such term is used under Section 13(d) of the Securities Exchange Act
of 1934, as amended); or

                  (ix) except with respect to matters covered by subparagraph
(i) -- (viii) above, as to which such applicable subparagraphs shall apply, the
Borrower otherwise shall breach any material term hereunder or under the other
Transaction Documents, including, without limitation, the representations and
warranties contained therein (i.e., in the event of a material breach as of the
date such representation and warranty was made) and if such breach is curable,
shall fail to cure such breach within ten business days after the Borrower has
been notified thereof in writing by the Holder;

then, upon the occurrence of any such Event of Default, at the option of the
Holder, exercisable in whole or in part at any time and from time to time by
delivery of a written notice to such effect (a "DEFAULT NOTICE") to the Borrower
while such Event of Default continues, the Borrower shall prepay, in
satisfaction of its obligation to pay the outstanding principal amount of this
Note and accrued and unpaid interest thereon, an amount equal to the Default
Amount (as defined in Section V.B below); provided, however, that (a) in the
case of an Event of Default described in clauses (vi) and (vii) of this Article
V.A, the Borrower's prepayment obligation hereunder shall be automatic and shall
not require the delivery of a Default Notice by the Holder, and (b) in the case
of an Event of Default resulting from a Legend Removal Failure, the Borrower's
prepayment obligation hereunder shall only apply to that portion of the Note
affected by such Legend Removal Failure. Such Default Amount, together with all
other ancillary amounts payable hereunder, shall immediately become due and
payable, all without demand, presentment or notice, all of which are hereby
expressly waived, together with all costs, including, without limitation, legal
fees and expenses of collection, and the Holder shall be entitled to exercise
all other rights and remedies available at law or in equity. For the avoidance
of doubt, the occurrence of any event described in clauses (i), (ii), (iii),
(vi), (vii) and (viii) above shall immediately constitute an Event of Default
and there shall be no cure period. Upon the Borrower's receipt of any Default
Notice hereunder, the Borrower shall immediately (and in any event within one
business day following such receipt) deliver a written notice (a "DEFAULT
ANNOUNCEMENT") to all Holders of the Notes stating the date upon which the
Borrower received such Default Notice and the amount of the Notes covered
thereby. Following the delivery of a Default Announcement hereunder, at any time
and from time to time, the Holder may request (either orally or in writing)
information from the Borrower with respect to the instant default (including,
but not limited to, the aggregate principal amount outstanding of Notes covered
by Default Notices received by the Borrower) and the Borrower shall furnish
(either orally or in writing) as soon as practicable such requested information
to the Holder.

         B. Definition of Default Amount. The "DEFAULT AMOUNT" with respect to
this Note means an amount equal to the greater of:

                                       6
<PAGE>

                  (i)             V                  M
                           ---------------      x
                                 CP

         and      (ii)     V   X   R

                  where:

                  "V" means the aggregate principal amount outstanding of the
Notes required to be prepaid plus all accrued and unpaid interest thereon
through the date of payment of the Default Amount hereunder;

                  "CP" means the Conversion Price in effect on the date on which
the Borrower receives the Default Notice;

                  "M" means (i) with respect to all Events of Default other than
Events of Default described in subparagraph (a) or (b) of Article V.A(viii)
hereof, the highest Closing Sales Price of the Borrower's Common Stock during
the period beginning on the date on which the Borrower receives the Default
Notice and ending on the date immediately preceding the date of payment of the
Default Amount hereunder, and (ii) with respect to an Event of Default described
in subparagraph (a) or (b) of Article V.A(viii) hereof, the greater of (a) the
amount determined pursuant to clause (i) of this definition or (b) the fair
market value, as of the date on which the Borrower receives the Default Notice,
of the consideration payable to the holder of a share of Common Stock pursuant
to the transaction which triggers the Event of Default. For purposes of this
definition, "fair market value" shall be determined by the mutual agreement of
the Borrower and the Majority Holders, or if such agreement cannot be reached
within five business days prior to the date of the Event of Default, by an
investment banking firm selected by the Borrower and reasonably acceptable to
the Majority Holders, with the costs of such appraisal to be borne by the
Borrower; and

                  "R" means 115%.

         C. Failure to Pay Default Amounts. If the Borrower fails to pay the
Holder the Default Amount with respect to any Note within five business days
after its receipt of a Default Notice (the "PREPAYMENT DATE"), then the Holder
shall be entitled to interest on the Default Amount at a per annum rate equal to
the lower of twenty percent (20%) and the highest interest rate permitted by
applicable law from the date on which the Borrower receives the Default Notice
until the date of payment of the Default Amount hereunder. In the event the
Borrower is not able to prepay all of the outstanding Notes required to be
prepaid on the Prepayment Date (including for such purpose all Notes subject to
Default Notices delivered prior to the Prepayment Date), the Borrower shall
prepay the outstanding Notes from each Holder pro rata, based on the total
amounts due on the Notes at the time of prepayment and required to be prepaid on
the Prepayment Date relative to the total amounts due under the Notes on the
Prepayment Date.

                                   ARTICLE VI
                       ADJUSTMENTS TO THE CONVERSION PRICE

         The Conversion Price shall be subject to adjustment from time to time
as follows:

         A. Stock Splits, Stock Dividends, Etc. If, at any time on or after the
Issuance Date, the number of outstanding shares of Common Stock is increased by
a stock split, stock dividend, combination, reclassification or other similar
event, the Conversion Price shall be proportionately reduced, or if the number
of outstanding shares of Common Stock is decreased by a reverse stock split,
combination, reclassification or other similar event, the Conversion Price shall
be proportionately increased. In such event, the Borrower shall notify the
Borrower's transfer agent of such change on or before the effective date
thereof.

         B. Merger, Consolidation, Etc.  If, at any time after the Issuance
Date, there shall be (i) any reclassification or change of the outstanding
shares of Common Stock (other than a change in par value, or from par value to
no par value, or from no par value to par value, or as a result of a subdivision
or combination), (ii) any consolidation or merger of the Borrower with any other
entity (other than a merger in which the Borrower is the

                                       7
<PAGE>

surviving or continuing entity and its capital stock is unchanged), (iii) any
sale or transfer of all or substantially all of the assets of the Borrower or
(iv) any share exchange or other transaction pursuant to which all of the
outstanding shares of Common Stock are converted into other securities or
property (each of (i) - (iv) above being a "CORPORATE CHANGE"), then the Holder
shall thereafter have the right to receive upon conversion, in lieu of the
shares of Common Stock otherwise issuable, such shares of stock, securities
and/or other property as would have been issued or payable in such Corporate
Change with respect to or in exchange for the number of shares of Common Stock
which would have been issuable upon conversion had such Corporate Change not
taken place (without giving effect to the limitations contained in Article
VIII), and in any such case, appropriate provisions (in form and substance
reasonably satisfactory to the Majority Holders) shall be made with respect to
the rights and interests of the Holder hereunder to the end that the economic
value of this Note is in no way diminished by such Corporate Change and that the
provisions hereof (including, without limitation, in the case of any such
consolidation, merger or sale in which the successor entity or purchasing entity
is not the Borrower, an immediate adjustment of the Conversion Price so that the
Conversion Price immediately after the Corporate Change reflects the same
relative value as compared to the value of the surviving entity's common stock
that existed between the Conversion Price and the value of the Borrower's Common
Stock immediately prior to such Corporate Change) shall thereafter be
applicable, as nearly as may be practicable in relation to any shares of stock
or securities thereafter deliverable upon the conversion thereof. The Borrower
shall not effect any Corporate Change unless (i) each Holder has received
written notice of such transaction at least 45 days prior thereto, but in no
event later than 15 days prior to the record date for the determination of
stockholders entitled to vote with respect thereto, and (ii) the resulting
successor or acquiring entity (if not the Borrower) assumes by written
instrument (in form and substance reasonable satisfactory to the Holder) the
obligations under this Note (including, without limitation, the obligation to
make interest payments accrued but unpaid through the date of such
consolidation, merger or sale and accruing thereafter). The above provisions
shall apply regardless of whether or not there would have been a sufficient
number of shares of Common Stock authorized and available for issuance upon
conversion of this Note as of the date of such transaction, and shall similarly
apply to successive reclassifications, consolidations, mergers, sales, transfers
or share exchanges.

         C. Distributions. If, at any time after the Issuance Date, the Borrower
shall declare or make any distribution of its assets (or rights to acquire its
assets) to holders of Common Stock as a partial liquidating dividend, by way of
return of capital or otherwise (including any dividend or distribution to the
Borrower's stockholders in cash or shares (or rights to acquire shares) of
capital stock of a subsidiary (i.e., a spin-off)) (a "DISTRIBUTION"), then the
Holder shall be entitled, upon any conversion of this Note after the date of
record for determining stockholders entitled to such Distribution (or if no such
record is taken, the date on which such Distribution is declared or made), to
receive the amount of such assets which would have been payable to the Holder
with respect to the shares of Common Stock issuable upon such conversion
(without giving effect to the limitations contained in Article VIII) had the
Holder been the holder of such shares of Common Stock on the record date for the
determination of stockholders entitled to such Distribution (or if no such
record is taken, the date on which such Distribution is declared or made).

         D. Convertible Securities and Purchase Rights. If, at any time after
the Issuance Date, the Borrower issues any securities or other instruments which
are convertible into or exercisable or exchangeable for Common Stock
("CONVERTIBLE SECURITIES") or options, warrants or other rights to purchase or
subscribe for Common Stock or Convertible Securities ("PURCHASE RIGHTS") pro
rata to the record holders of the Common Stock, whether or not such Convertible
Securities or Purchase Rights are immediately convertible, exercisable or
exchangeable, then the Holder shall be entitled, upon any conversion of this
Note after the date of record for determining stockholders entitled to receive
such Convertible Securities or Purchase Rights (or if no such record is taken,
the date on which such Convertible Securities or Purchase Rights are issued), to
receive the aggregate number of Convertible Securities or Purchase Rights which
the Holder would have received with respect to the shares of Common Stock
issuable upon such conversion (without giving effect to the limitations
contained in Article VIII) had the Holder been the holder of such shares of
Common Stock on the record date for the determination of stockholders entitled
to receive such Convertible Securities or Purchase Rights (or if no such record
is taken, the date on which such Convertible Securities or Purchase Rights were
issued). If the right to exercise or convert any such Convertible Securities or
Purchase Rights would expire in accordance with their terms prior to the
conversion of this Note, then the terms of such Convertible Securities or
Purchase Rights shall provide that such exercise or convertibility right shall
remain in effect until 30 days after the date the Holder receives such
Convertible Securities or Purchase Rights pursuant to the conversion hereof.

                                       8

         E.       Dilutive Issuances.

                  (i) Adjustment Upon Dilutive Issuance. If, at any time after
the Issuance Date, the Borrower issues or sells, or in accordance with
subparagraph (ii) of this Article VI.E is deemed to have issued or sold, any
shares of Common Stock for no consideration or for a consideration per share
less than the Conversion Price on the date of issuance or sale (or deemed
issuance or sale) (a "DILUTIVE ISSUANCE"), then effective immediately upon the
Dilutive Issuance, the Conversion Price shall be adjusted so as to equal an
amount determined by multiplying such Conversion Price by the following
fraction:

                                     N0 + N1
                                     -------
                                     N0 + N2

                  where:

                  N0 = the number of shares of Common Stock outstanding
immediately prior to the issuance, sale or deemed issuance or sale of such
additional shares of Common Stock in such Dilutive Issuance (without taking into
account any shares of Common Stock issuable upon conversion, exchange or
exercise of any Convertible Securities or Purchase Rights, including the Notes
and Warrants);

                  N1 = the number of shares of Common Stock which the aggregate
consideration, if any, received or receivable by the Borrower for the total
number of such additional shares of Common Stock so issued, sold or deemed
issued or sold in such Dilutive Issuance (which, in the case of a deemed
issuance or sale, shall be calculated in accordance with subparagraph (ii)
below) would purchase at the Conversion Price in effect immediately prior to
such Dilutive Issuance; and

                  N2 = the number of such additional shares of Common Stock so
issued, sold or deemed issued or sold in such Dilutive Issuance.

Notwithstanding the foregoing, no adjustment shall be made pursuant to this
Paragraph E if such adjustment would result in an increase in the Conversion
Price.

                  (ii) Effect on Conversion Price of Certain Events. For
purposes of determining the adjusted Conversion Price under subparagraph (i) of
this Article VI.E, the following will be applicable:

                           (a) Issuance of Purchase Rights. If the Borrower
issues or sells any Purchase Rights, whether or not immediately exercisable, and
the price per share for which Common Stock is issuable upon the exercise of such
Purchase Rights (and the price of any conversion of Convertible Securities, if
applicable) is less than the Conversion Price in effect on the date of issuance
or sale of such Purchase Rights, then the maximum total number of shares of
Common Stock issuable upon the exercise of all such Purchase Rights (assuming
full conversion, exercise or exchange of Convertible Securities, if applicable)
shall, as of the date of the issuance or sale of such Purchase Rights, be deemed
to be outstanding and to have been issued and sold by the Borrower for such
price per share. For purposes of the preceding sentence, the "price per share
for which Common Stock is issuable upon the exercise of such Purchase Rights"
shall be determined by dividing (A) the total amount, if any, received or
receivable by the Borrower as consideration for the issuance or sale of all such
Purchase Rights, plus the minimum aggregate amount of additional consideration,
if any, payable to the Borrower upon the exercise of all such Purchase Rights,
plus, in the case of Convertible Securities issuable upon the exercise of such
Purchase Rights, the minimum aggregate amount of additional consideration
payable upon the conversion, exercise or exchange thereof (determined in
accordance with the calculation method set forth in subparagraph (ii)(b) of this
Article VI.E) at the time such Convertible Securities first become convertible,
exercisable or exchangeable, by (B) the maximum total number of shares of Common
Stock issuable upon the exercise of all such Purchase Rights (assuming full
conversion, exercise or exchange of Convertible Securities, if applicable). No
further adjustment to the Conversion Price shall be made upon the actual
issuance of such Common Stock upon the exercise of such Purchase Rights or upon
the conversion, exercise or exchange of Convertible Securities issuable upon
exercise of such Purchase Rights.

                                       9
<PAGE>

                           (b) Issuance of Convertible Securities. If the
Borrower issues or sells any Convertible Securities, whether or not immediately
convertible, exercisable or exchangeable, and the price per share for which
Common Stock is issuable upon such conversion, exercise or exchange is less than
the Conversion Price in effect on the date of issuance or sale of such
Convertible Securities, then the maximum total number of shares of Common Stock
issuable upon the conversion, exercise or exchange of all such Convertible
Securities shall, as of the date of the issuance or sale of such Convertible
Securities, be deemed to be outstanding and to have been issued and sold by the
Borrower for such price per share. If the Convertible Securities so issued or
sold do not have a fluctuating conversion or exercise price or exchange ratio,
then for the purposes of the preceding sentence, the "price per share for which
Common Stock is issuable upon such conversion, exercise or exchange" shall be
determined by dividing (A) the total amount, if any, received or receivable by
the Borrower as consideration for the issuance or sale of all such Convertible
Securities, plus the minimum aggregate amount of additional consideration, if
any, payable to the Borrower upon the conversion, exercise or exchange thereof
(determined in accordance with the calculation method set forth in this
subparagraph (ii)(b) of this Article VI.E) at the time such Convertible
Securities first become convertible, exercisable or exchangeable, by (B) the
maximum total number of shares of Common Stock issuable upon the exercise,
conversion or exchange of all such Convertible Securities. If the Convertible
Securities so issued or sold have a fluctuating conversion or exercise price or
exchange ratio (a "VARIABLE RATE CONVERTIBLE SECURITY"), then for purposes of
the next preceding sentence, the "price per share for which Common Stock is
issuable upon such conversion, exercise or exchange" shall be deemed to be the
lowest price per share which would be applicable (assuming all holding period
and other conditions to any discounts contained in such Variable Rate
Convertible Security have been satisfied) if the conversion price of such
Variable Rate Convertible Security on the date of issuance or sale thereof was
seventy-five percent (75%) of the actual conversion price on such date (the
"ASSUMED VARIABLE MARKET PRICE"), and, further, if the conversion price of such
Variable Rate Convertible Security at any time or times thereafter is less than
or equal to the Assumed Variable Market Price last used for making any
adjustment under this Article VI.E with respect to any Variable Rate Convertible
Security, the Conversion Price in effect at such time shall be readjusted to
equal the Conversion Price which would have resulted if the Assumed Variable
Market Price at the time of issuance of the Variable Rate Convertible Security
had been seventy-five percent (75%) of the actual conversion price of such
Variable Rate Convertible Security existing at the time of the adjustment
required by this sentence. No further adjustment to the Conversion Price shall
be made upon the actual issuance of such Common Stock upon conversion, exercise
or exchange of such Convertible Securities.

                           (c) Change in Option Price or Conversion Rate. If
there is a change at any time in (A) the amount of additional consideration
payable to the Borrower upon the exercise of any Purchase Rights; (B) the amount
of additional consideration, if any, payable to the Borrower upon the
conversion, exercise or exchange of any Convertible Securities; or (C) the rate
at which any Convertible Securities are convertible into or exercisable or
exchangeable for Common Stock (in each such case, other than under or by reason
of provisions designed to protect against dilution and except when an adjustment
is made to a Variable Rate Security pursuant to Article VI.E(ii)(b)), the
Conversion Price in effect at the time of such change shall be readjusted to the
Conversion Price which would have been in effect at such time had such Purchase
Rights or Convertible Securities still outstanding provided for such changed
additional consideration or changed conversion, exercise or exchange rate, as
the case may be, at the time initially issued or sold.

                           (d) Calculation of Consideration Received. If any
Common Stock, Purchase Rights or Convertible Securities are issued or sold for
cash, the consideration received therefor will be the amount received by the
Borrower therefor. In case any Common Stock, Purchase Rights or Convertible
Securities are issued or sold for a consideration part or all of which shall be
other than cash, including in the case of a strategic or similar arrangement in
which the other entity will provide services to the Borrower, purchase services
from the Borrower or otherwise provide intangible consideration to the Borrower,
the amount of the consideration other than cash received by the Borrower
(including the net present value of the consideration expected by the Borrower
for the provided or purchased services) shall be the fair market value of such
consideration, except where such consideration consists of securities, in which
case the amount of consideration received by the Borrower will be the Closing
Sales Price thereof as of the date of receipt. In case any Common Stock,
Purchase Rights or Convertible Securities are issued in connection with any
merger or consolidation in which the Borrower is the surviving corporation, the
amount of consideration therefor will be deemed to be the fair market value of
such portion of the net assets and business of the non-surviving entity as is
attributable to such Common Stock, Purchase Rights or Convertible Securities, as
the case may be. Notwithstanding anything else herein to the contrary, if Common
Stock, Purchase Rights or Convertible Securities are issued or sold in
conjunction with each other as part of a single transaction or in a series of
related

                                       10
<PAGE>

transactions, the Holder may elect to determine the amount of consideration
deemed to be received by the Borrower therefor by deducting the fair value of
any type of securities (the "DISREGARDED SECURITIES") issued or sold in such
transaction or series of transactions. If the Holder makes an election pursuant
to the immediately preceding sentence, no adjustment to the Conversion Price
shall be made pursuant to this Article VI.E for the issuance of the Disregarded
Securities or upon any conversion, exercise or exchange thereof. For example, if
the Borrower were to issue convertible notes having a face value of $1,000,000
and warrants to purchase shares of Common Stock at an exercise price equal to
the market price of the Common Stock on the date of issuance of such warrants in
exchange for $1,000,000 of consideration, the fair value of the warrants would
be subtracted from the $1,000,000 of consideration received by the Borrower for
the purposes of determining whether the shares of Common Stock issuable upon
conversion of the convertible notes shall be deemed to be issued at a price per
share below the Conversion Price then in effect and, if so, for purposes of
determining any adjustment to the Conversion Price hereunder as a result of the
issuance of the convertible notes. The Borrower shall calculate, using standard
commercial valuation methods appropriate for valuing such assets, the fair
market value of any consideration other than cash or securities; provided,
however, that if the Holder does not agree to such fair market value calculation
within three business days after receipt thereof from the Borrower, then such
fair market value shall be determined in good faith by an investment banker or
other appropriate expert of national reputation selected by the Borrower and
reasonably acceptable to the Holder, with the costs of such appraisal to be
borne by the Borrower.

                           (e) Issuances Pursuant to Existing Securities. If the
Borrower issues (or becomes obligated to issue) shares of Common Stock pursuant
to any antidilution or similar adjustments (other than as a result of stock
splits, stock dividends and the like) contained in any Convertible Securities or
Purchase Rights outstanding as of the date hereof but not included in Section
3(c) of the Disclosure Schedule to the Securities Purchase Agreement, then all
shares of Common Stock so issued shall be deemed to have been issued for no
consideration. If the Borrower issues (or becomes obligated to issue) shares of
Common Stock pursuant to any antidilution or similar adjustments contained in
any Convertible Securities or Purchase Rights included in Section 3(c) of the
Disclosure Schedule to the Securities Purchase Agreement as a result of the
issuance of the Notes or Warrants and the number of shares that the Borrower
issues (or is obligated to issue) as a result of such initial issuance exceeds
the amount specified in Section 3(c) of the Disclosure Schedule to the
Securities Purchase Agreement, such excess shares shall be deemed to have been
issued for no consideration.

                  (iii) Limitation on Adjustments for Dilutive Issuances.
Notwithstanding the foregoing or any other provision of this Note to the
contrary, in no event shall the Conversion Price be adjusted as a result of a
Dilutive Issuance to the extent (but only to the extent) that such adjustment
would result in this Note, together with all other Notes (including any portions
of any Notes that have already been converted into Common Stock) and all
Warrants (including any Warrants that have already been exercised for Common
Stock), being convertible into and exercisable for more than an aggregate of
3,000,487 shares of Common Stock. In the event that any Dilutive Issuance would
result in an adjustment to the Conversion Price of the Notes and such adjustment
is limited by operation of this Paragraph E(iii), such adjustment shall be
allocated pro rata among the Notes then outstanding. In the event that any
Dilutive Issuance would result in an adjustment to both the Conversion Price of
the Notes and the Exercise Price of the Warrants and such adjustment is limited
by operation of this Paragraph E(iii), such adjustment shall first be made to
the Conversion Price of the Notes to the maximum extent possible within the
limitations of this Paragraph E(iii) (allocated pro rata in accordance with the
foregoing sentence), and only if such adjustment has been made in full shall any
adjustments be made to the Exercise Price of the Warrants (subject to any
similar limitations set forth therein).

         F. Exceptions to Adjustment of Conversion Price. Notwithstanding the
foregoing, no adjustment to the Conversion Price shall be made upon (i) the
issuance of Common Stock upon the exercise or conversion of any Convertible
Securities or Purchase Rights outstanding on the Issuance Date and disclosed in
Section 3(c) of the Disclosure Schedule to the Securities Purchase Agreement in
accordance with the terms of such Convertible Securities and Purchase Rights as
of such date; (ii) the grant of options to purchase Common Stock, with exercise
prices not less than the market price of the Common Stock on the date of grant,
or the grant of restricted shares of Common Stock, in each case which are issued
to employees, officers, directors or consultants of the Borrower for the primary
purpose of soliciting or retaining their employment or service pursuant to an
equity compensation plan approved by the Borrower's Board of Directors, and the
issuance of shares of Common Stock upon the exercise thereof; (iii) the issuance
of securities pursuant to a bona fide underwritten public offering; or (iv) the
issuance of shares of Common Stock upon conversion of the Notes or the exercise
of the Warrants; (v) the issuance of securities

                                       11
<PAGE>

in a bona fide business acquisition; or (vi) the issuance of securities in
connection with a strategic business partnership with an oil and gas company,
the primary purpose of which, in the reasonable judgment of the Borrower's Board
of Directors, is not to raise additional capital.

         G. Other Action Affecting Conversion Price. If, at any time after the
Issuance Date, the Borrower takes any action affecting the Common Stock that
would be covered by Article VI.A through E, but for the manner in which such
action is taken or structured, which would in any way diminish the value of the
Notes, then the Conversion Price shall be adjusted in such manner as the Board
of Directors of the Borrower shall in good faith determine to be equitable under
the circumstances.

         H. Notice of Adjustments. Upon the occurrence of each adjustment or
readjustment of the Conversion Price pursuant to this Article VI amounting to a
more than one percent (1%) change in such Conversion Price, or any change in the
number or type of stock, securities and/or other property issuable upon
conversion of the Notes, the Borrower, at its expense, shall promptly compute
such adjustment or readjustment or change and prepare and furnish to the Holder
a certificate setting forth such adjustment or readjustment or change and
showing in detail the facts upon which such adjustment or readjustment or change
is based. The Borrower shall, upon the written request at any time of the
Holder, furnish to the Holder a like certificate setting forth (i) such
adjustment or readjustment or change, (ii) the Conversion Price at the time in
effect and (iii) the number of shares of Common Stock and the amount, if any, of
other securities or property which at the time would be received upon conversion
of the Notes.

                                   ARTICLE VII
                    CONSENT RIGHTS; NOTICE OF CERTAIN ACTIONS

         A. Consent Rights. So long as any Notes are outstanding, the Borrower
shall not take any of the following corporate actions (whether by merger,
consolidation or otherwise) without first obtaining the approval (by vote or
written consent) of the Majority Holders:

                  (i)      alter or change the rights, preferences or privileges
of the Notes;

                  (ii)     issue any additional Notes;

                  (iii) redeem, repurchase or otherwise acquire, or declare or
pay any cash dividend or distribution on, any securities of the Borrower, except
pursuant to any equity compensation plan approved by the Borrower's Board of
Directors;

                  (iv) issue any debt securities or incur any indebtedness that
would have priority over the Notes upon liquidation of the Borrower (except for
borrowings under the Borrower's existing credit facility with KeyBank N.A. and
any renewal, refinancing or replacement of such facility not involving an
increase in the principal amount thereof, an increase in the interest rate due
thereon or a change in any other material term thereof), or redeem, repurchase,
prepay or otherwise acquire any outstanding debt securities or indebtedness of
the Borrower, except as expressly required by the terms of such securities or
indebtedness;

                  (v)      enter into any agreement, commitment, understanding
or other arrangement to take any of the foregoing actions; or

                  (vi)     cause or authorize any subsidiary of the Borrower to
engage in any of the foregoing actions.

Notwithstanding the foregoing, no change pursuant to this Article VII shall be
effective to the extent that, by its terms, it applies to less than all of the
Holders of the Notes then outstanding.

         B. Approval of Certain Transactions. In the event that the Borrower
desires to enter into any transaction that would result in (i) the sale,
conveyance or disposition of all or substantially all of its assets (the
presentation of any such transaction for stockholder approval being conclusive
evidence that such transaction

                                       12
<PAGE>

involves the sale of all or substantially all of the assets of the Borrower), or
(ii) the merger or consolidation of the Borrower with or into any person or
entity, which results in either (a) the holders of the voting securities of the
Borrower immediately prior to such transaction holding or having the right to
direct the voting of fifty percent (50%) or less of the total outstanding voting
securities of the Borrower or such other surviving or acquiring person or entity
immediately following such transaction or (b) the members of the board of
directors or other governing body of the Borrower comprising fifty percent (50%)
or less of the members of the board of directors or other governing body of the
Borrower or such other surviving or acquiring person or entity immediately
following such transaction, then the Borrower shall be permitted to seek the
approval of the Holder for such transaction in advance of its entering into such
transaction, and if the Holder so approves the transaction and the Borrower
enters into and consummates such transaction within 90 days following such
approval on terms no less favorable to the Borrower than those presented to the
Holder for purposes of obtaining such approval, then such transaction shall not
constitute an Event of Default under Section V.A(viii).

         C. Notice Rights. In addition to the foregoing consent rights, the
Borrower shall provide the Holder with prior notification of any meeting of the
stockholders (and copies of proxy materials and other information sent to
stockholders). If the Borrower takes a record of its stockholders for the
purpose of determining stockholders entitled to (i) receive payment of any
dividend or other distribution, any right to subscribe for, purchase or
otherwise acquire (including by way of merger, consolidation or
recapitalization) any share of any class or any other securities or property, or
to receive any other right, or (ii) to vote in connection with any proposed
sale, lease or conveyance of all or substantially all of the assets of the
Borrower, or any proposed merger, consolidation, liquidation, dissolution or
winding up of the Borrower, the Borrower shall mail a notice to the Holder, at
least 15 days prior to the record date specified therein (or 45 days prior to
the consummation of the transaction or event, whichever is earlier, but in no
event earlier than public announcement of such proposed transaction), of the
date on which any such record is to be taken for the purpose of such vote,
dividend, distribution, right or other event, and a brief statement regarding
the amount and character of such vote, dividend, distribution, right or other
event to the extent known at such time.

                                  ARTICLE VIII
          LIMITATIONS ON CERTAIN CONVERSIONS, REDEMPTIONS AND TRANSFERS

         In no event shall the Borrower issue Common Stock to the Holder in
connection with the repayment of this Note pursuant to Article I.B or Mandatory
Conversion of this Note pursuant to Article II.C, and in no event shall the
Holder have the right to effect an Optional Conversion of this Note into shares
of Common Stock or to dispose of this Note to the extent that such repayment,
conversion or right to effect such conversion or disposition would result in the
Holder and its affiliates together beneficially owning more than 4.99% of the
outstanding shares of Common Stock. For purposes of this Article VIII,
beneficial ownership shall be determined in accordance with Section 13(d) of the
Securities Exchange Act of 1934, as amended, and Regulation 13D-G thereunder.
The restriction contained in this Article VIII may not be altered, amended,
deleted or changed in any manner whatsoever unless the holders of a majority of
the outstanding shares of Common Stock and the Holder shall approve, in writing,
such alteration, amendment, deletion or change. In the event that the Borrower
is prohibited from issuing shares of Common Stock in connection with the
repayment of this Note pursuant to Article I.B as a result of the operation of
this Article VIII, the Borrower shall make such repayment in cash. In the event
that the Borrower is prohibited from issuing shares of Common Stock upon a
Mandatory Conversion pursuant to Article II.C as a result of the operation of
this Article VIII, the Borrower shall pay to the Holder an amount of cash equal
to the Closing Sales Price of the Common Stock on the Conversion Date multiplied
by the number of shares of Common Stock that the Borrower is prohibited from
issuing as a result of the operation of this Article VIII.

                                   ARTICLE IX
                               CERTAIN DEFINITIONS

         For purposes of this Note, in addition to the other terms defined
herein, the following terms shall have the following meanings:

         A. "BUSINESS DAY" means any day, other than a Saturday or Sunday or a
day on which banking institutions in the State of New York are authorized or
obligated by law, regulation or executive order to close.

                                       13
<PAGE>

         B. "CLOSING SALES PRICE" means, for any security as of any date, the
last sales price of such security on the principal trading market where such
security is listed or traded as reported by Bloomberg Financial Markets (or a
comparable reporting service of national reputation selected by the Borrower and
reasonably acceptable to the Majority Holders if Bloomberg Financial Markets is
not then reporting closing bid prices of such security) (in any case,
"BLOOMBERG"), or if the foregoing does not apply, the last reported sales price
of such security on a national exchange or in the over-the-counter market on the

Mandatory Conversion (as defined in Article II.C), that date specified in the
notice delivered to the Holders in the event that such Mandatory Conversion

                                  MISCELLANEOUS

         A. Failure or Indulgency Not Waiver. No failure or delay on the part of
any Holder in the exercise of any power, right or privilege hereunder shall
operate as a waiver thereof, nor shall any single or partial exercise of any
such power, right or privilege preclude other or further exercise thereof or of
any other right, power or privilege.

         B. Lost or Stolen Notes. Upon receipt by the Borrower of (i) evidence
of the loss, theft, destruction or mutilation of any Note and (ii) (y) in the
case of loss, theft or destruction, of indemnity (without any bond or other
security) reasonably satisfactory to the Borrower, or (z) in the case of
mutilation, the Note (surrendered for cancellation), the Borrower shall execute
and deliver a new Note of like tenor and date. However, the Borrower shall not
be obligated to reissue such lost, stolen, destroyed or mutilated Note if the
Holder contemporaneously requests the Borrower to convert such Note.

         C. Allocation of Reserved Amount. The initial Reserved Amount shall be
allocated pro rata among the Holders of the Notes based on the principal amount
of Notes issued to each Holder. Each increase to the Reserved Amount shall be
allocated pro rata among the Holders of the Notes based on the principal amount
of Notes held by each Holder at the time of the increase in the Reserved Amount.
In the event a Holder shall sell or otherwise transfer any of such Holder's
Notes, each transferee shall be allocated a pro rata portion of such
transferor's Reserved Amount. Any portion of the Reserved Amount which remains
allocated to any person or entity which does not hold any Notes shall be
allocated to the remaining Holders of the Notes, pro rata based on the principal
balance of Notes then held by such Holders.

         D. Quarterly Statements of Available Shares. For each calendar quarter
beginning in the quarter in which the initial registration statement required to
be filed pursuant to Section 2(a) of the Registration Rights Agreement is
declared effective and thereafter for so long as any Notes are outstanding, the
Borrower shall deliver (or cause its transfer agent to deliver) to the Holder a
written report notifying the Holder of any occurrence that prohibits the
Borrower from issuing Common Stock upon any conversion. The report shall also
specify (i) the total principal amount of Notes outstanding as of the end of
such quarter, (ii) the total number of shares of Common Stock issued upon all
conversions of Notes prior to the end of such quarter, (iii) the total number of
shares of Common Stock which are reserved for issuance upon conversion of the
Notes as of the end of such quarter and (iv) the total number of shares of
Common Stock which may thereafter be issued by the Borrower upon conversion of
the Notes before the Borrower would exceed the Reserved Amount. The Borrower (or
its transfer agent) shall use its best efforts to deliver the report for each
quarter to the Holder prior to the tenth day of the calendar month following the
quarter to which such report relates. In addition, the Borrower (or its transfer
agent) shall provide, as promptly as practicable following delivery to the
Borrower of a written request by the Holder, any of the information enumerated
in clauses (i) - (iv) of this Paragraph D as of the date of such request.

         E. Status as Stockholder. Upon submission of a Notice of Conversion by
the Holder, (i) the shares covered thereby (other than the shares, if any, which
cannot be issued because their issuance would exceed the Holder's allocated
portion of the Reserved Amount) shall be deemed converted into shares of Common
Stock and (ii) the Holder's rights as a holder of such converted Note shall
cease and terminate, excepting only the right to receive certificates for such
shares of Common Stock and to any remedies provided herein or otherwise
available at law or in equity to the Holder because of a failure by the Borrower
to comply with the terms of this Note. Notwithstanding the foregoing, if the
Holder has not received certificates for all shares of Common Stock prior to the
sixth business day after the expiration of the Delivery Period with respect to a
conversion of this Note for any reason, then (unless the Holder otherwise elects
to retain its status as a holder of Common Stock by so notifying the Borrower
within five business days after the expiration of such six business day period
after expiration of the Delivery Period) the Holder shall regain the rights of a
holder of this Note and the Borrower shall, as soon as practicable, return such
unconverted Note to the Holder. In all cases, the Holder shall retain all of its
rights and remedies for the Borrower's failure to convert this Note.

         F. Remedies Cumulative. The remedies provided in this Note shall be
cumulative and in addition to all other remedies available under this Note, at
law or in equity (including a decree of specific performance and/or other
injunctive relief), and nothing herein shall limit the Holder's right to pursue
actual damages for any failure by

                                       15
<PAGE>

the Borrower to comply with the terms of this Note. The Borrower acknowledges
that a breach by it of its obligations hereunder will cause irreparable harm to
the Holder and that the remedy at law for any such breach may be inadequate. The
Borrower therefore agrees, in the event of any such breach or threatened breach,
that the Holder shall be entitled, in addition to all other available remedies,
to an injunction restraining any breach, without the necessity of showing
economic loss and without any bond or other security being required.

         G. Waiver. Notwithstanding any provision in this Note to the contrary,
any provision contained herein and any right of the Holder granted hereunder may
be waived as to all Notes (and the Holders thereof) upon the written consent of
the Majority Holders, unless a higher percentage is required by applicable law,
in which case the written consent of the Holders of not less than such higher
percentage of Notes shall be required.

         H. Notices. Any notices required or permitted to be given under the
terms hereof shall be sent by certified or registered mail (return receipt
requested) or delivered personally, by responsible overnight carrier or by
confirmed facsimile, and shall be effective five days after being placed in the
mail, if mailed, or upon receipt or refusal of receipt, if delivered personally
or by responsible overnight carrier or confirmed facsimile, in each case
addressed to a party. The addresses for such communications are:

         I. Amendment Provision. This Note and any provision hereof may be
amended only by an instrument in writing signed by the Borrower and the Holder.

         J. Assignability. This Note shall be binding upon the Borrower and its
successors and assigns and shall inure to the benefit of the Holder and its
successors and assigns. Notwithstanding anything to the contrary contained in
this Note or the Transaction Documents, this Note may be pledged and all rights
of the Holder under this Note may be assigned to any affiliate or to any other
person or entity without the consent of the Borrower.

         K. Cost of Collection. If an Event of Default occurs hereunder, the
Borrower shall pay the Holder hereof costs of collection, including reasonable
attorneys' fees.

         L. Governing Law; Jurisdiction. This Note shall be governed by and
construed in accordance with the laws of the State of Delaware applicable to
contracts made and to be performed in the State of Delaware. The Borrower
irrevocably consents to the jurisdiction of the United States federal courts and
the state courts located in the County of New Castle, State of Delaware, in any
suit or proceeding based on or arising under this Note and irrevocably agrees
that all claims in respect of such suit or proceeding may be determined in such
courts. The Borrower irrevocably waives the defense of an inconvenient forum to
the maintenance of such suit or proceeding in such forum. The Borrower further
agrees that service of process upon the Borrower mailed by first class mail
shall be deemed in every respect effective service of process upon the Borrower
in any such suit or proceeding. Nothing herein shall affect the right of the
Holder to serve process in any other manner permitted by law. The Borrower
agrees that a final non-appealable judgment in any such suit or proceeding shall
be conclusive and may be enforced in other jurisdictions by suit on such
judgment or in any other lawful manner.

                                       16

         M. Denominations. At the request of the Holder, upon surrender of this
Note, the Borrower shall promptly issue new Notes in the aggregate outstanding
principal amount hereof, in the form hereof, in such denominations of at least
$25,000 as the Holder shall request.

         N. Certain Waivers. The Borrower and each endorser hereby waive
presentment, notice of nonpayment or dishonor, protest, notice of protest and
all other notices in connection with the delivery, acceptance, performance,
default or enforcement of payment of this Note, and hereby waive all notice or
right of approval of any extensions, renewals, modifications or forbearances
which may be allowed.

         O. Severability. If any provision of this Note shall be invalid or
unenforceable in any jurisdiction, such invalidity or unenforceability shall not
affect the validity or enforceability of the remainder of this Note or the
validity or enforceability of this Note in any other jurisdiction.

         P. Maximum Interest Rate. If the effective interest rate on this Note
would otherwise violate any applicable usury law, then the interest rate shall
be reduced to the maximum permissible rate and any payment received by the
Holder in excess of the maximum permissible rate shall be treated as a
prepayment of the principal of this Note.
