                         SECURITIES PURCHASE AGREEMENT


    This Agreement, dated effective October 2, 2001, is between NORTH AMERICAN
TECHNOLOGIES GROUP, INC., a Delaware corporation (the "Company"), and AVALANCHE
RESOURCES, LTD., a Texas limited partnership (the "Purchaser").


    1.  Sale and Purchase of Common Stock.

        (a) Consideration for Issuance.

            (i) Subject to the terms and conditions of this Agreement, the
Company agrees to issue and sell to Purchaser the Required Number (defined
below) of shares of the Company's common stock, and in exchange for the issuance
to Purchaser of the Required Number of such shares Purchaser agrees to pay the
Company the amount of $500,000.00 (the "Cash Consideration") and to transfer and
assign to the Company 235,294 shares of the common stock of Universal Display
Corporation, a Pennsylvania corporation ("Universal Display") and Warrant
#PP2000-62 (the "Warrant") issued by Universal Display for the purchase of
235,294 shares of the common stock of Universal Display upon the terms and
conditions of the Warrant. The shares of Universal Display common stock to be
transferred and assigned to the Company are referred to in this Agreement as the
"Universal Display Shares." The Universal Display Shares and the Warrant are
referred to collectively in this Agreement as the "Universal Display
Securities." The Required Number of shares of the Company's common stock to be
issued to Purchaser pursuant to this Agreement are referred to in this Agreement
as the "Purchased Shares." The term "Common Stock" means the shares of common
stock of the Company of the par value of $.001 each.

            (ii) The Cash Consideration shall be payable as provided in
Paragraph 6(a). The Universal Display Securities shall be transferred and
assigned to the Company at the Closing (as defined below).

            (iii) The Required Number shall be determined immediately prior to
the issuance of the Purchased Shares from the following formula:

             X = .55 (Outstanding Shares) - 1,000,000
                 ____________________________________
                                 .45

    where:

        "X" equals the Required Number; and
<PAGE>

        "Outstanding Shares" equals: (A) the number of shares of Common Stock
outstanding immediately prior to the issuance of the Purchased Shares; plus (B)
the number of additional shares of Common Stock which would be outstanding if
all shares of capital stock (including all accrued dividends thereon)
convertible or exchangeable into shares of Common Stock and outstanding
immediately prior to the issuance of the Purchased Shares were converted or
exchanged into shares of Common Stock immediately prior to the issuance of the
Purchased Shares; plus (C) the number of additional shares of Common Stock which
would be outstanding if all notes (including all accrued interest thereon)
convertible into shares of Common Stock and outstanding immediately prior to the
issuance of the Purchased Shares were converted into shares of Common Stock
immediately prior to the issuance of the Purchased Shares; plus (D) the number
of additional shares of Common Stock which would be outstanding if all options,
warrants or any other rights to acquire shares of Common Stock and outstanding
immediately prior to the issuance of the Purchased Shares were exercised
immediately prior to the issuance of the Purchased Shares, whether or not such
rights are then exercisable pursuant to the terms of such rights.  For purposes
of computing the Required Number, the number of Outstanding Shares shall be
computed in each instance specified above on the basis that all shares of Common
Stock issuable pursuant to the conversion, exchange, or exercise rights
specified above were issued and outstanding immediately prior to the issuance of
the Purchased Shares.  The parties agree that the Required Number is
approximately 22,000,000. The term "Convertible Notes" means all notes
convertible into shares of Common Stock.  The term "Options" means all
Convertible Notes and all options, warrants or any other rights to acquire
shares of Common Stock.

        (b) Issuance.  The Company agrees to issue the Purchased Shares to
Purchaser within ten days after the Company completes the Required Transactions
(defined below), but in any event not later than January 31, 2002.  The Company
shall be deemed to have issued the Purchased Shares to Purchaser upon the
Company's delivery of instructions to its transfer agent to issue a certificate
to Purchaser for the Purchased Shares provided such certificate is issued to
Purchaser not later than February 28, 2002.  The date the Company delivers such
instructions to the transfer agent after the Company's completion of the
Required Transactions is referred to in this Agreement as the "Issuance Date."

    2.  Loan. At the Closing, Purchaser agrees to loan the principal amount of
$500,000.00 to the Company, which loan (the "Loan") shall be repayable by the
Company pursuant to the terms of the promissory note in the form of that
attached hereto as Exhibit A (the "Note"). The Company agrees to execute the
Note at the Closing.

    3.  Additional Terms of Purchase/Sale.

        (a) Security Documents.  The Company's payment of the Note and the
Company's obligation to issue the Purchased Shares after the Closing shall be
secured by a lien and security interest in all assets of the Company owned at
the Closing or acquired after the Closing pursuant to the Security Agreement in
the form of that attached hereto as Exhibit B (the "Security Agreement").  The
Company shall execute the Security Agreement at the Closing.
<PAGE>

        (b) Proxy.  At the Closing the Company shall deliver or cause to be
delivered to Purchaser a proxy executed by each person listed on the attached
Exhibit C with respect to the shares of voting securities of the Company owned
by such person as set forth on Exhibit C.  Each proxy shall be in the form of
that attached hereto as Exhibit D.

        (c) Directors. At the Closing, the Company shall have taken all action
required under applicable law, its articles of incorporation and bylaws (the
"Governance Documents") and any agreement to which the Company or its assets are
bound (the "Applicable Agreements") to increase the number of directors of the
Company to eleven and to enable Purchaser to elect designees of Purchaser as six
of the eleven directors (the "Purchaser's Designees") at the Closing and
continuing thereafter from time to time until the issuance of the Purchased
Shares.

directors to approve and authorize the Required Transactions or to not block or
oppose the approval and authorization of the Required Transactions by the other
directors.

    7.  Restrictions on Purchased Shares.

        (a) Restricted Securities.  Upon issuance the Purchased Shares will be
"restricted securities" as that term is defined under Rule 144 of the Securities
Act of 1933, as amended (the "Securities Act"), and, accordingly, may not be
offered for sale or sold or otherwise transferred in a transaction which would
constitute a sale thereof within the meaning of the Securities Act unless: (i)
such security has been registered for sale under the Securities Act and
registered or qualified under applicable state securities laws relating to the
offer and sale of securities; or (ii) exemptions from the registration
requirements of the Securities Act and the registration or qualification
requirements of all such state securities laws are available and the
<PAGE>

Company shall have received an opinion of counsel that the proposed sale or
other disposition of such securities may be effected without registration under
the Securities Act and would not result in any violation of any applicable state
securities laws relating to the registration or qualification of securities for
sale, such counsel and such opinion to be satisfactory to the Company. As
restricted securities, the Purchased Shares will be subject to significant
restrictions upon resale.

        (b) Private Placement.  The parties agree that the Purchased Shares
subject to this Agreement are offered (the "Offering") by the Company as a
private placement transaction pursuant to Section 4(2) of the Securities Act.

    8.  Representations and Warranties of Purchaser. Purchaser represents and
warrants to the Company as follows:

        (a) Organization and Standing of Purchaser. Purchaser is a duly
organized and validly existing limited partnership in good standing under the
laws of Texas with adequate power and authority to conduct the business in which
it is now engaged and has the corporate power and authority to enter into this
Agreement and each of the Exhibits attached hereto, and is duly qualified and
licensed to do business as a foreign limited partnership in such other states or
jurisdictions as is necessary to enable it to carry on its business, except
where failure to do so would not have a material adverse effect on its business.

        (b) Power and Authority.  The execution and delivery of this Agreement
and any Exhibit attached hereto and the transactions contemplated thereby have
been duly authorized by the partners of Purchaser and will not constitute or
result in a breach or default under, or conflict with, any order, ruling or
regulation of any court or other tribunal or of any governmental commission or
agency, or any agreement or other undertaking, to which Purchaser is a party or
by which Purchaser is bound, and, if Purchaser is not an individual, will not
violate any provision of the partnership agreement of Purchaser.  The signatures
on this Agreement and Exhibit E attached hereto are genuine, and the signatory
has been duly authorized to execute the same.  No other act or proceeding on the
part of Purchaser or any partner therein is necessary to authorize this
Agreement or the consummation of the transactions contemplated thereby. When
duly executed and delivered by the parties hereto, this Agreement will
constitute a valid and legally binding obligation of Purchaser enforceable
against it in accordance with its terms, except as such enforceability may be
limited by (i) bankruptcy, insolvency, moratorium, reorganization or other
similar laws and legal and equitable principles limiting or affecting the rights
of creditors generally; and/or (ii) general principles of equity, regardless of
whether considered in a proceeding in equity or at law.

        (c) Accredited Investor.  Purchaser has such knowledge and experience
in business and financial matters such that such Partner is capable of
evaluating the merits and risks of purchasing the Purchased Shares.  Purchaser
is an "accredited investor" as that term is defined in Rule 501 of Regulation D
of the Securities Act and satisfies the suitability standards identified in this
Agreement.
<PAGE>

        (d) Loss of Investment.  Purchaser's overall commitment to investments
which are not readily marketable is not disproportionate to its net worth and
its investment in the Company will not cause such overall commitment to become
excessive.  Purchaser can afford to bear the loss of its entire investment in
the Company and has adequate means of providing for its current needs and has no
need for liquidity in his investment in the Company.

        (e) Special Suitability.  Purchaser satisfies any special suitability
or other applicable requirements applicable to residents or domiciliaries of
Texas.

        (f) Investment Intent.

            (i) Purchaser has been advised that this Offering has not been
registered with, or reviewed by, the Securities and Exchange Commission ("SEC")
because this Offering is intended to be a non-public offering pursuant to
Section 4(2) and Rule 506 of Regulation D of the Securities Act.  Purchaser
represents that the Purchased Shares are being purchased for Purchaser's own
account and not on behalf of any other person, for investment purposes only and
not with a view towards distribution or resale to others.  Purchaser agrees that
Purchaser will not attempt to sell, transfer, assign, pledge or otherwise
dispose of all or any portion of the Purchased Shares unless the Purchased
Shares to be disposed of are registered under the Securities Act or unless in
the opinion of counsel an exemption from such registration is available, such
counsel and such opinion to be satisfactory to the Company.  Purchaser
understands that the Purchased Shares have not been registered under the
Securities Act by reason of a claimed exemption under the provisions of the
Securities Act which depends, in part, upon Purchaser's investment intention;
and

            (ii) the Purchased Shares and any certificates issued in replacement
therefor shall bear the following legend, in addition to any other legend
required by law or otherwise:

     "THE SECURITIES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN REGISTERED
     UNDER THE SECURITIES ACT OF 1933, AS AMENDED.  THE SECURITIES REPRESENTED
     BY THIS CERTIFICATE HAVE BEEN TAKEN BY THE REGISTERED OWNER FOR INVESTMENT,
     AND WITHOUT A VIEW TO RESALE OR DISTRIBUTION THEREOF, AND MAY NOT BE
     TRANSFERRED OR DISPOSED OF WITHOUT AN OPINION OF COUNSEL SATISFACTORY TO
     THE ISSUER THAT SUCH TRANSFER OR DISPOSITION DOES NOT VIOLATE THE
     SECURITIES ACT OF 1933, AS AMENDED, OR THE RULES AND REGULATIONS
     THEREUNDER."

        (g) State Securities Laws.  Purchaser understands that no securities
administrator of any state has made any finding or determination relating to the
fairness of this investment and that no securities administrator of any state
has recommended or endorsed, or will recommend or endorse, the offering of the
Purchased Shares.
<PAGE>

        (h) No General Solicitation.  Purchaser acknowledges that no general
solicitation or general advertising (including communications published in any
newspaper, magazine or other broadcast) has been received by it and that no
public solicitation or advertisement with respect to the offering of the
Purchased Shares has been made to it.

        (i) Advice of Tax and Legal Advisors. Purchaser has relied solely upon
the advice of its own tax and legal advisors with respect to the tax and other
legal aspects of this investment.

        (j) Access to Information. Purchaser has had access to all material and
relevant information concerning the Company, its management, financial
condition, capitalization, market information, properties and prospects
necessary to enable Purchaser to make an informed investment decision with
respect to its investment in the Purchased Shares. Purchaser has carefully read
and reviewed, and is familiar with and understands the contents thereof and
hereof, including, without limitation, the risk factors described in this
Agreement. Purchaser acknowledges that it has had the opportunity to ask
questions of and receive answers from, and to obtain additional information
from, representatives of the Company concerning the terms and conditions of the
acquisition of the Purchased Shares and the present and proposed business and
financial condition of the Company, and has had all such questions answered to
its satisfaction and has been supplied all information requested.

        (k) SEC Reports.  Purchaser acknowledges that it has been advised of
the availability of and has carefully reviewed a copy of the Company's Annual
Report on Form 10-KSB for the year ended December 31, 2000 and its Quarterly
Report on Form 10-QSB for the three months ended June 30, 2001 (collectively,
the "SEC Reports").

        (l) Universal Display Securities.  Purchaser owns the Universal
Display Securities free from any setoff, claim, restriction, lien, security
interest or encumbrance; that the Universal Display Securities are freely
transferable, Purchaser has been advised that the Universal Display Registration
Statement on Form S-3 filed with the SEC on May 14, 2001 has been declared
effective, and Purchaser has received no notice from Universal Display or
otherwise that sales may not be made thereunder, whether as a result of a black-
out, lock-up or otherwise.

    9.  Understanding of Investment Risks. An investment in the Purchased Shares
should not be made by a purchaser who cannot afford the loss of the entire
consideration paid for the Purchased Shares. Purchaser acknowledges that the
Purchased Shares offered hereby have not been approved or disapproved by the
SEC, or any state securities commissions, nor has the SEC or any state
securities commission passed upon the adequacy or accuracy of this Agreement or
any exhibit hereto. Prior to making an investment in the Purchased Shares,
Purchaser has fully considered, among other things, the business risks discussed
in the Company's SEC Reports.

    10. Representations and Warranties of the Company. The Company hereby
represents and warrants to Purchaser as follows:
<PAGE>

        (a) Organization and Standing of the Company.  The Company is a duly
organized and validly existing corporation in good standing under the laws of
Delaware with adequate power and authority to conduct the business in which it
is now engaged and has the corporate power and authority to enter into this
Agreement and perform its obligations under this Agreement, subject, however, to
Paragraph 11.  The Company is duly qualified and licensed to do business as a
foreign corporation in such other states or jurisdictions as is necessary to
enable it to carry on its business, except where failure to do so would not have
a material adverse effect on its business.

        (b) Corporate Power and Authority.  The execution and delivery of this
Agreement and each of the Exhibits attached hereto and the transactions
contemplated thereby have been duly authorized by the Board of Directors of the
Company.  Subject to Paragraph 7, no other corporate act or proceeding on the
part of the Company is  necessary to authorize this Agreement or the
consummation of the transactions contemplated thereby. When duly executed and
delivered by the parties hereto, this Agreement will constitute a valid and
legally binding obligation of the Company enforceable against it in accordance
with its terms, except as such enforceability may be limited by (i) bankruptcy,
insolvency, moratorium, reorganization or other similar laws and legal and
equitable principles limiting or affecting the rights of creditors generally;
and/or (ii) general principles of equity, regardless of whether considered in a
proceeding in equity or at law.

        (c) Issuance of Securities.  Upon their issuance and for the
consideration set forth in and in accordance with the terms of this Agreement,
the Purchased Shares shall be duly and validly issued, fully paid and
nonassessable.

        (d) SEC Reports; Absence of Certain Events.  The Company has timely
filed all reports required to be filed with the SEC pursuant to the Securities
Act or the Securities Exchange Act of 1934, as amended (the "Exchange Act"), and
the rules promulgated thereunder, and has previously advised Purchaser of the
availability of true and complete copies of such SEC Reports.  Such SEC Reports,
as of their respective dates, complied in all materials respects with the
applicable requirements of the Securities Act and the Exchange Act, as the case
may be, and none of such SEC Reports contained any untrue statement of a
material fact or omitted to state a material fact required to be stated therein
or necessary to make the statements therein, in light of the circumstances under
which they were made, not misleading.  Except as set forth in the SEC Reports,
there has not been any fact, event, circumstance or change affecting or relating
to the Company which has had or is reasonably likely to have, individually or in
the aggregate, a material adverse effect on the Company; provided, however, that
a material adverse effect shall not include any adverse effect following the
date of this Agreement which is solely attributable to (i) the announcement or
pendency of the transactions contemplated by this Agreement or (ii) changes in
national economic conditions or industry conditions generally.

        (e) Attached hereto as Schedule 10(e) is a list of the number of
outstanding shares of capital stock of the Company and the debt issued by the
Company which is convertible into shares of capital stock of the Company,
including in each instance the dividends that would
<PAGE>

be in arrears, and unpaid interest that would have accrued, as of December 31,
2001 if the Company did not pay any dividends or interest between the date of
this Agreement and December 31, 2001.

    11. Required Actions. The parties recognize that the Company has not
obtained (but must obtain not later than January 31, 2002) the approvals,
consents, agreements and other actions as may be required for the Company to
effect the Required Transactions pursuant to Paragraph 5.

    12. IMPORTANT CONSIDERATIONS: SUITABILITY STANDARDS - WHO SHOULD INVEST.

        (a) INVESTMENT IN THE COMMON STOCK INVOLVES A HIGH DEGREE OF RISK AND
IS SUITABLE ONLY FOR PERSONS OF SUBSTANTIAL FINANCIAL RESOURCES WHO HAVE NO NEED
FOR LIQUIDITY IN THEIR INVESTMENT.  A substantial number of state securities
commissions have established investor suitability standards for the marketing
within their respective jurisdictions of restricted securities. Some have also
established minimum dollar levels for purchases in their states.  The reasons
for these standards appear to be, among others, the relative lack of liquidity
of securities of such programs as compared with other securities investments.
Investment in the Purchased Shares involves a high degree of risk and is
suitable only for persons of substantial financial means who have no need for
liquidity in their investments.

        (b) The Company requires, as a general investor suitability standard,
that Purchaser and the general partner of Purchaser represent in writing: (a) it
is acquiring the Purchased Shares for investment and not with a view to resale
or distribution; (b) it can bear the economic risk of losing its entire
investment; (c) its overall commitment to investments which are not readily
marketable is not disproportionate to its net worth, and an investment in the
Purchased Shares will not cause such overall commitment to become excessive; (d)
it has adequate means of providing for its current needs and has no need for
liquidity in this investment in the Purchased Shares; (e) it has evaluated all
the risks of investment in the Company; and (f) it has such knowledge and
experience in financial and business matters as to be capable of evaluating the
merits and risks of investing in the Company or is relying on its own purchaser
representative, in making an investment decision.

        (c) The suitability standards referred to above represent minimum
suitability requirements for prospective purchasers and the satisfaction of such
standards by a prospective purchaser does not necessarily mean that the
Purchased Shares is a suitable investment for such purchaser. The Company may,
in circumstances it deems appropriate, modify such requirements. The Company may
also reject subscriptions for whatever reasons, in its sole discretion, it deems
appropriate.

        (d) THE EXECUTION AND DELIVERY OF THIS AGREEMENT BY THE COMPANY DOES
NOT CONSTITUTE A DETERMINATION BY THE COMPANY THAT AN INVESTMENT IN THE COMMON
STOCK IS SUITABLE FOR A PROSPECTIVE
<PAGE>

PURCHASER. THE FINAL DETERMINATION OF THE SUITABILITY OF INVESTMENT IN THE
COMMON STOCK MUST BE MADE BY PURCHASER AND ITS ADVISERS.

    13. Additional Investment Considerations.

        (a) IN MAKING AN INVESTMENT DECISION, PURCHASER MUST RELY ON ITS OWN
EXAMINATION OF THE COMPANY AND THE TERMS OF THE OFFERING, INCLUDING THE MERITS
AND RISKS INVOLVED.  THE PURCHASED SHARES HAVE NOT BEEN RECOMMENDED BY ANY
FEDERAL OR STATE SECURITIES COMMISSION OR REGULATORY AUTHORITY.  ANY
REPRESENTATION TO THE CONTRARY IS A CRIMINAL OFFENSE.

        (b) THE SECURITIES ARE SUBJECT TO RESTRICTIONS ON TRANSFERABILITY AND
RESALE AND MAY NOT BE TRANSFERRED OR RESOLD EXCEPT AS PERMITTED UNDER THE
SECURITIES ACT AND THE APPLICABLE STATE SECURITIES LAWS, PURSUANT TO
REGISTRATION OR EXEMPTION THEREFROM.  THE PURCHASER AND EACH OF THE SHAREHOLDERS
SHOULD BE AWARE THAT IT MAY BE REQUIRED TO BEAR THE FINANCIAL RISKS OF THIS
INVESTMENT FOR AN INDEFINITE PERIOD OF TIME.

    14. Post-Closing Funding/Investments.

        (a) Ventures.  For a period of at least one year after the Closing,
the chief executive officer of Purchaser's general partner shall serve as an
executive officer of the Company responsible for the Company's sale or other
disposition of the Universal Display Securities, including any securities
acquired through the exercise of the Warrant, and finding suitable investments
for a venture subsidiary to be created by the Company.  The Company's Board of
Directors will may form an investment committee to approve, price and oversee
any transaction of the venture subsidiary.  The committee will consist of five
members, three members to be designated by Purchaser's Designees and two members
to be designated by directors who are not Purchaser's Designees, and the
subsidiary's investments will be funded with debt or another non-equity type of
funding source.

        (b) Additional Funds. The parties recognize that the Company will need
additional working capital to fund its operations.  After the Closing Purchaser
will attempt to locate additional sources of capital to provide not less than $2
million of additional working capital as needed by the Company.  The working
capital may be provided as cash or third-party debt or a combination of cash or
third-party debt and may be provided by Purchaser or its affiliates directly or
by third parties.  However, Purchaser will have no liability to the Company if
such third-party sources are not located or if Purchaser or its affiliates do
not provide the additional working capital directly.

    15. Registration Rights. The Company agrees as follows:
<PAGE>

        (a) Certain Additional Defined Terms. For the purpose of this Paragraph
15, the following definitions shall apply:

            (i) "Exchange Act" shall mean the Securities Exchange Act of 1934.

            (ii) "Registration Statement" shall mean the Registration Statement
of the Company filed with the SEC pursuant to the provisions of Paragraph 15(b)
of this Agreement which covers the resale of Purchased Shares on an appropriate
form then permitted by the SEC to be used for such registration and the sales
contemplated to be made thereby under the Securities Act, or any similar rule
that may be adopted by the SEC, and all amendments and supplements to such
Registration Statement, including any pre- and post- effective amendments
thereto, in each case including the prospectus contained therein, all exhibits
thereto and all materials incorporated by reference therein.

            (iii) "Restricted Stock" shall mean the Purchased Shares and any
additional shares of Common Stock or other equity securities of the Company
issued or issuable after the date hereof in respect of any such securities by
way of a stock dividend or stock split, in connection with a combination,
exchange, reorganization, recapitalization or reclassification of Company's
securities, or pursuant to a merger, division, consolidation or other similar
business transaction or combination involving the Company; provided that as to
any particular shares of Restricted Stock, such securities shall cease to
constitute Restricted Stock (A) when a registration statement with respect to
the sale of such securities shall have become effective under the Securities Act
and such securities shall have been disposed of thereunder, or (B) when and to
the extent such securities are permitted to be distributed pursuant to Rule 144
(or any successor provision to such Rule) under the Securities Act or are
otherwise freely transferable to the public without further registration under
the Securities Act.

        (b) Piggyback Registration Rights.

            (i) The Company shall advise Purchaser by written notice prior to
the filing of a Registration Statement under the Securities Act (excluding
registration on Forms S-8, S-4, 10 or any successor forms thereto), covering
securities of the Company to be offered and sold by any holder of securities of
the Company, and shall, upon the request of Purchaser given within five (5)
business days of the notice given by the Company, include in any such
Registration Statement such information as may be required to permit a public
offering of the Restricted Stock purchased hereby. Purchaser shall furnish such
information as may be reasonably requested by the Company in order to include
such Restricted Stock in the Registration Statement. Notwithstanding the
foregoing, the Company may withdraw any registration statement referred to in
this Paragraph 15(b) without thereby incurring liability to the holders of the
Restricted Stock.

            (ii) Notwithstanding anything to the contrary contained herein, the
Company's obligation in this Paragraph 15(b) shall extend only to the inclusion
of the Restricted Stock in a Registration Statement filed under the Securities
Act.  The Company shall have no obligation to assure the terms and conditions of
distribution, to obtain a commitment from an
<PAGE>

underwriter relative to the sale of the Restricted Stock or to otherwise assume
any responsibility for the manner, price or terms of the distribution of the
Restricted Stock. Furthermore, the Company shall not be restricted in any manner
from including within the Registration Statement or the distribution, issuance
or resale of any of its or any other securities.

            (iii)  Notwithstanding anything to the contrary contained herein, if
the offer of shares on a Registration Statement on which the Purchaser proposes
to register Restricted Stock is an underwritten registration and the managing

the period in which all shares of Restricted Stock covered thereby shall have
been sold or two (2) years from the effective date of the first Registration
Statement filed by the Company with the SEC pursuant to this Agreement;

            (viii) if the Purchased Shares are listed on any securities exchange

each selling stockholder whose Shares are covered by such registration
statement, or by such persons other than the Company (except to the extent the
Company may be a seller) as they may agree.

        (e) Obligations of Purchaser.

            (i) In connection with each registration hereunder, Purchaser,
should it elect to participate in resales under such registration, will furnish
to the Company in writing such information with respect to Purchaser and the
securities held by Purchaser, and the proposed distribution by it as shall be
reasonably requested by the Company in order to assure compliance with federal
and applicable state securities laws, as a condition precedent to including
Purchaser's Restricted Stock in the Registration Statement. Purchaser also shall
promptly notify the Company of any changes in such information included in the
Registration Statement or prospectus as a result of which there is an untrue
statement of material fact or an omission to state any material fact required or
necessary to be stated therein in order to make the statements contained therein
not misleading in light of the circumstances then existing.

            (ii) In connection with each registration pursuant to this
Agreement, Purchaser agrees that it will not effect sales of any Restricted
Stock until notified by the Company of the effectiveness of the Registration
Statement, and thereafter will suspend such sales after receipt of telegraphic
or written notice from the Company to suspend sales to permit the Company to
correct or update a Registration Statement or prospectus. At the end of any
period during which the Company is obligated to keep a Registration Statement
current, Purchaser shall discontinue sales of Restricted Stock pursuant to such
Registration Statement upon receipt of notice from the Company of its intention
to remove from registration the Restricted Stock covered by such Registration
Statement which remain unsold, and Purchaser shall notify the Company of the
number of shares registered which remain unsold immediately upon receipt of such
notice from the Company.

        (f) Information Blackout, Holdbacks and Lock-Ups.

            (i) At any time when a Registration Statement effected pursuant to
Paragraph 15(b) relating to Restricted Stock is effective, upon written notice
from the Company to Purchaser that the Company has determined in good faith that
the sale of Restricted Stock
<PAGE>

pursuant to the Registration Statement would require disclosure of non-public
material information, Purchaser shall suspend sales of Restricted Stock pursuant
to such Registration Statement until such time as the Company notifies Purchaser
that such material information has been disclosed to the public or has ceased to
be material or that sales pursuant to such Registration Statement may otherwise
be resumed.

            (ii) Notwithstanding any other provision of this Agreement,
Purchaser shall not effect any public sale or distribution (including sales
pursuant to Rule 144), if and when available, of equity securities of the
Company, or any securities convertible into or exchangeable or exercisable for
such securities, during the thirty (30) days prior to the commencement of any
primary offering to be undertaken by the Company of shares of its unissued
common stock (the "Primary Offering"), which may also include other securities,
and ending 120 days after completion of any such Primary Offering, unless the
Company, in the case of a non-underwritten Primary Offering, or the managing
underwriter, in the case of an underwritten Primary Offering, otherwise agree.

        (g) Indemnification.

            (i) The Company agrees to indemnify, to the extent permitted by law,
Purchaser, its partners and each Person who controls Purchaser (within the
meaning of the Securities Act) against all losses, claims, damages, liabilities
and expenses caused by any untrue statement of material fact contained in any
Registration Statement, prospectus or preliminary prospectus or any amendment
thereof or supplement thereto or any omission of a material fact required to be
stated therein or necessary to make the statements therein not misleading,
except insofar as the same are caused by or contained in any information
furnished to the Company by or on behalf of Purchaser for use therein or by
Purchaser's failure to deliver a copy of the Registration Statement or
prospectus or any amendments or supplements thereto after the Company has
furnished Purchaser with a sufficient number of copies of the same.

            (ii) In connection with any Registration Statement in which
Purchaser is participating, Purchaser shall furnish to the Company in writing
such information and affidavits as the Company reasonably requests for use in
connection with any such Registration Statement or prospectus and, to the extent
permitted by law, shall indemnify the Company, its directors and officers and
each Person who controls the Company (within the meaning of the Securities Act)
against any losses, claims, damages, liabilities and expenses resulting from:
(i) any untrue or alleged untrue statement of material fact contained in the
Registration Statement, prospectus or preliminary prospectus or any amendment
thereof or supplement thereto or any omission or alleged omission of a material
fact required to be stated therein or necessary to make the statements therein
not misleading, (but only to the extent that such untrue statement or omission
is contained in any information or affidavit so furnished by Purchaser); or (ii)
any disposition of the Restricted Stock in a manner that fails to comply with
the permitted methods of distribution identified within the Registration
Statement.

            (iii) Any person entitled to indemnification hereunder shall (i)
give prompt written notice to the indemnifying party of any claim with respect
to which it seeks
<PAGE>

indemnification (provided that the failure to give prompt notice shall not
impair any Person's right to indemnification hereunder to the extent such
failure has not prejudiced the indemnifying party) and (ii) unless in such
indemnified party's reasonable judgment a conflict of interest between such
indemnified and indemnifying parties may exist with respect to such claim,
permit such indemnifying party to assume the defense of such claim with counsel
reasonably satisfactory to the indemnified party. If such defense is assumed,
the indemnifying party shall not be subject to any liability for any settlement
made by the indemnified party without its consent (but such consent shall not be
unreasonably withheld). An indemnifying party who is not entitled to, or elects
not to, assume the defense of a claim shall not be obligated to pay the fees and
expenses of more than one counsel for all parties indemnified by such
indemnifying party with respect to such claim, unless in the reasonable judgment
of any indemnified party a conflict of interest may exist between such
indemnified party and any other of such indemnified parties with respect to such
claim.

            (iv) The indemnification provided for under this Agreement shall
remain in full force and effect regardless of any investigation made by or on
behalf of the indemnified party or any officer, director or controlling Person
of such indemnified party and shall survive the transfer of securities.  The
Company also agrees to make such provisions, as are reasonably requested by any
indemnified party, for contribution to such party in the event the Company's
indemnification is unavailable for any reason.

general intangibles in collateral, at the time and in the form requested by
secured party; and (iv) deliver upon request to secured party shipping and
delivery receipts evidencing the shipment of goods and invoices evidencing the
receipt of, and the payment for, inventory in collateral.

        (g) Additional Documents.  Debtor shall sign any papers furnished by
secured party and take any other actions which are necessary in the judgment of
secured party to obtain, maintain and perfect this security interest.

        (h) Parties Liable.  Debtor will preserve the liability of all
obligors on any collateral, will preserve the priority of all security therefor,
and upon secured party's request will deliver to secured party the original
certificates of title on all motor vehicles securing the collateral.  Secured
party shall have no duty to preserve such liability or security, but may do so
at the expense of debtor, without waiving debtor's default.

        (i) Modification. Without the written consent of secured party, debtor
shall not agree to any modification of any of the terms of any accounts,
contracts, chattel paper, general intangibles or instruments in collateral.

        (j) Debtor Notification.  At any time following a default hereunder or
under the note secured party may notify persons obligated on any collateral to
make payments directly to secured party and secured party may take control of
all proceeds of any collateral. Until secured party elects to exercise such
rights, debtor, as agent of secured party, shall collect and enforce all
payments owed on collateral.
<PAGE>

        (k) Receipts/Rejected Goods. Upon secured party's demand following a
default hereunder or under the note, debtor will deposit, upon receipt and in
the form received, with any necessary indorsement, all payments received as
proceeds of collateral, in a special bank account in a bank of secured party's
choice over which secured party alone shall have power of withdrawal.  The funds
in said account shall secure the obligation.  Secured party is authorized to
make any indorsement in debtor's name and behalf. Pending such deposit, debtor
shall not mingle any such payments with any of debtor's other funds or property,
but will hold them separate and upon an express trust for secured party.
Secured party may from time to time apply the whole or any part of the funds in
the special account against the obligation.

        (l) Records.  Debtor at all times will maintain accurate books and
records covering the collateral. Debtor immediately will mark all books and
records with an entry showing the assignment of all accounts in collateral to
secured party and secured party is hereby given the right to audit the books and
records of debtor relating to collateral at any time and from time to time.

        (m) Disposition.  If disposition of any collateral gives rise to an
account, chattel paper or instrument, debtor immediately shall notify secured
party, and upon request of secured party shall assign or indorse the same to
secured party.  No collateral may be sold, leased, manufactured, processed or
otherwise disposed of by debtor in any manner without the prior written consent
of secured party, except inventory sold, leased, manufactured, processed or
consumed in the ordinary course of business.

        (n) Accounts.  Each account in collateral will represent the valid and
legally enforceable obligation of third parties.

        (o) Location.  Debtor shall give secured party written notice of each
office of debtor in which records of debtor pertaining to accounts in collateral
are kept, and of any change of any such location. If no such notice is given,
all records of debtor pertaining to accounts and all inventory are and shall be
kept at debtor's address shown above.

        (p) Changes.  Debtor will notify secured party immediately of any
material change in the collateral, of a change in any manner warranted or
represented by debtor in this agreement or furnished to secured party, and of
any event of default.

        (q) Use/Removal.  Debtor will not use the collateral illegally or
permit the collateral to be affixed to real or personal property without the
written consent of secured party.  Debtor will keep all collateral at debtor's
address shown above.

        (r) Possession.  If the collateral is chattel paper, documents,
instruments or investment securities or other instruments, secured party may
deliver a copy of this agreement to the broker or seller thereof, or any person
in possession thereof, and such delivery shall constitute notice to such person
of secured party's security interest therein and shall constitute debtor s
instruction to such person to deliver to secured party certificates or other
evidence of the same as soon as available.  Debtor will deliver all investment
securities and other instruments, documents
<PAGE>

and chattel paper which are part of the collateral and in debtor's possession to
the secured party immediately, or if hereafter acquired, immediately following
acquisition, appropriately indorsed to secured party's order or with appropriate
executed powers. Debtor waives presentment, demand, notice of dishonor, protest,
and all other notices with respect thereof.

        (s) Chattel Paper.  Debtor has perfected or will perfect a security
interest by means satisfactory to secured party in goods covered by chattel
paper in collateral.

        (t) Intentionally left blank.

        (u) Change of Name. Without the written consent of secured party, debtor
shall not change its name or the state of its incorporation.

        (v) Power of Attorney. Debtor appoints secured party debtor's
attorney-in-fact with full power in debtor's name and behalf to do every act
which debtor is obligated to do or may be required to do hereunder; however,
nothing in this paragraph shall be construed to obligate secured party to take
any action hereunder.

        (w) Waivers.  Debtor waives notice of the creation, advance, increase,
existence, extension or renewal of, and of any indulgence with respect to, the
obligation; waives presentment, demand, notice of dishonor, and protest; waives
notice of the amount of the obligation outstanding at any time, notice of any
change in financial condition of any person liable for the obligation or any
part thereof, and all other notices respecting the obligation; and agrees that
maturity of the obligation and any part thereof may be accelerated, extended or
renewed one or more times by secured party in its discretion, without notice to
debtor.

        (x) Other Parties/Collateral.  No renewal or extension of or any other
indulgence with respect to the obligation or any part thereof, no release of any
security, no release of any person (including any maker, indorser, guarantor or
surety) liable on the obligation, no delay in enforcement of payment, and no
delay or omission or lack of diligence or care in exercising any right or power
with respect to the obligation or any security therefor or guaranty thereof or
under this agreement shall in any manner impair or affect the rights of secured
party under the law, hereunder, or under any other agreement pertaining to the
collateral. Secured party need not file suit or assert a claim for personal
judgment against any person for any part of the obligation or seek to realize
upon any other security for the obligation before foreclosing upon the
collateral for the purpose of paying the obligation.  Debtor waives any right to
the benefit of or to require or control application of any other security or
proceeds thereof, and agrees that secured party shall have no duty or obligation
to debtor to apply to the obligation any such other security or proceeds
thereof.

    8.  Rights and Powers of Secured Party.

        (a) General.  Secured party before or after default and without
liability to debtor may: obtain from any person information regarding debtor or
debtor's business, which information any such person also may furnish without
liability to debtor; require debtor to give
<PAGE>

possession or control of any collateral to secured party; indorse as debtor's
agent any instruments, documents or chattel paper in collateral or representing
proceeds of collateral; contact account debtors directly to verify information
furnished by debtor; release collateral in its possession to any debtor,
temporarily or otherwise; reject as unsatisfactory any property hereafter
offered by debtor as collateral; set standards from time to time to govern what
may be used as after acquired collateral, designate, from time to time, a
certain percent of the collateral as the loan value and require debtor to
maintain the obligation at or below such figure; take control of funds generated
by the collateral and use same to reduce any part of the obligation. Secured
party shall not be liable for failure to collect any account or instrument, or
for any act or omission on the part of the secured party, its officers, agents
or employees, except willful misconduct. The foregoing rights and powers of
secured party will be in addition to, and not a limitation upon, any rights and
powers of secured party given by law, elsewhere in this agreement, or otherwise.

        (b) Convertible Securities.  Secured party may present for conversion
any instrument or investment security in collateral which is convertible into
any other instrument or investment or a combination thereof and cash, but
secured party shall not have any duty to present for conversion any instrument
in collateral unless it shall have received from debtor detailed written
instructions to that effect at a time reasonably far in advance of the final
conversion date to make such conversion possible.

    9.  Default.

        (a) Events of Default. The following are events of default hereunder:

            (i) default in the timely payment or the performance of any part of
the obligation or in performance or observance of the terms and conditions
herein;

            (ii) any warranty, representation or statement made or furnished to
secured party herein, heretofore, or hereafter proves to have been false in any
material respect when made or furnished;

            (iii) acceleration of the maturity of debt of debtor to any other
person;

            (iv) substantial change in any fact warranted or represented in this
agreement or in any other agreement between debtor and secured party or in any
statement, schedule, or other writing furnished in connection therewith;

            (v) loss, theft, destruction or encumbrance or sale or transfer of
any collateral in violation hereof, or substantial damage to any collateral;

            (vi) dissolution, merger or consolidation, termination of existence,
insolvency or business failure of debtor; commencement of proceedings for the
appointment of a receiver for any property of debtor, or commission of an act of
bankruptcy by debtor; commencement of any proceeding under any bankruptcy or
insolvency law by or against debtor (or any corporate action shall be taken to
effect same), or any partnership of which debtor is a
<PAGE>

partner or by or against any person liable upon the obligation or any part
thereof, or liable upon collateral;

            (vii) levy on, seizure or attachment of any property of debtor; or

            (viii) a judgment against debtor becomes final.

        (b) Remedies.  When an event of default occurs, and at any time
thereafter, secured party without notice or demand may declare the obligation in
whole or in part immediately due and may enforce payment of the same and
exercise any rights under the UCC, rights and remedies of secured party under
this agreement, or otherwise.  Secured party may require debtor to assemble the
collateral and make it available to secured party at a place which is reasonably
convenient to both parties.  Unless the collateral is perishable or threatens to
decline speedily in value or is of a type customarily sold on a recognized
market, secured party will give debtor reasonable notice of the time and place
of any public sale thereof or of the time after which any private sale or other
intended disposition thereof is to be made.  Expenses of retaking, holding,
preparing for sale, selling, leasing or the like shall include secured party's
reasonable attorney's fees.  Secured party shall be entitled to immediate
possession of all books and records evidencing any accounts or general
intangibles or pertaining to chattel paper covered by this agreement and shall
have the authority to enter upon any premises upon which any of the same, or any
collateral, may be situated and to remove the same therefrom without liability.
Secured party may surrender any insurance policies in collateral and receive the
unearned premium thereon.  Debtor shall be entitled to any surplus and shall be
liable to secured party for any deficiency.  The proceeds of any disposition
after default available to satisfy the obligation shall be applied to the
obligation in such order and in such manner as secured party in its discretion
shall decide.  If, in the opinion of secured party, there is any question that a
public sale or distribution of any collateral will violate any state or federal
securities law, secured party (i) may offer and sell securities privately to
purchasers who will agree to take them for investment purposes and not with a
view to distribution and who will agree to imposition of restrictive legends on
the certificates representing the security, or (ii) may sell such securities in
an intrastate offering under Section 3(a)(11) of the Securities Act of 1933, and
any sale so made in good faith by secured party shall be deemed to be
"commercially reasonable."

    10. General.

        (a) Parties Bound.  Secured party's rights hereunder shall inure to
the benefit of its successors and assigns, and in the event of any assignment or
transfer of any of the obligation or the collateral, secured party thereafter
shall be fully discharged from any responsibility with respect to the collateral
so assigned or transferred, but secured party shall retain all rights and powers
hereby given with respect to any of the obligation or collateral not so assigned
or transferred.  All representations, warranties and agreements of debtor if
more than one are joint and several, and all shall be binding upon the personal
representatives, heirs, successors and assigns of debtor.
<PAGE>

        (b) Waiver. No delay of secured party in exercising any power or right
shall operate as a waiver thereof; nor shall any single or partial exercise of
any power or right preclude other or further exercise thereof or the exercise of
any other power or right.  No waiver by secured party of any right hereunder or
of any default by debtor shall be binding upon secured party unless in writing,
and no failure by secured party to exercise any power or right hereunder or
waiver of any default by debtor shall operate as a waiver of any other or
further exercise of such right or power or of any further default.

        (c) Agreement Continuing. This agreement shall constitute a continuing
agreement, applying to all future as well as existing transactions, whether or
not of the character contemplated at the date of this agreement, and if all
transactions between secured party and debtor shall be closed at any time shall
be equally applicable to any new transactions thereafter. Provisions of this
agreement, unless by their terms exclusive, shall be in addition to other
agreements between the parties.

        (d) Definitions.  Unless the context indicates otherwise, definitions
in the UCC apply to words and phrases in this agreement; if UCC definitions
conflict, Chapter 9 definitions apply.

        (e) Notice. Notice shall be deemed reasonable if mailed postage prepaid
at least 5 days before the related action (or if the UCC elsewhere specifies a
longer period, such longer period) to the address of debtor given above.

        (f) Interest. No agreement relating to the obligation shall be construed
to be a contract for or to authorize charging or receiving, or require the
payment or permit the collection of, interest at a rate or in an amount above
that authorized by law. Interest payable under any agreement above that
authorized by law shall be reduced automatically to the highest amount permitted
by law. This provision shall override and supersede all other provisions of any
agreement relating to the obligation.

        (g) Modifications. No provision hereof shall be modified or limited
except by a written agreement expressly referring hereto and to the provisions
so modified or limited and signed by the debtor and secured party, nor by course
of conduct, usage of trade, or by the law merchant.

        (h) Severability.  The unenforceability of any provision of this
agreement shall not affect the enforceability or validity of any other
provision.

        (i) Gender and Number.  Where appropriate, the use of one gender shall
be construed to include the others or any of them, and the singular number shall
be construed to include the plural, and vice versa.

        (j) Applicable Law. This agreement shall be construed according to the
laws of Texas.

        (k) Financing Statement.  A carbon, photographic or other reproduction
of this agreement or any financing statement covering the collateral shall be
sufficient as a financing statement.

option may pay any such costs and expenses, discharge encumbrances on
collateral, and pay for insurance of collateral and such payment shall be a part
of the obligation. Debtor agrees to reimburse secured party on demand for any
reasonable costs so incurred.

        (f) Information/Inspection. Debtor shall (i) furnish secured party upon
request any financial statements of debtor or reports to debtor by accountants

to inspect and copy, or furnish secured party with copies of, all records

on any collateral, will preserve the priority of all security therefor, and upon
secured party's request will deliver to secured party the original certificates

contracts, chattel paper, general intangibles or instruments in collateral.

        (j) Debtor Notification. At any time following a default hereunder or
under the note secured party may notify persons obligated on any collateral to
make payments directly to secured party and secured party may take control of
all proceeds of any collateral. Until secured party elects to exercise such
rights, debtor, as agent of secured party, shall collect and enforce all
payments owed on collateral.
<PAGE>

        (k) Receipts/Rejected Goods. Upon secured party's demand following a
default hereunder or under the note, debtor will deposit, upon receipt and in
the form received, with any necessary indorsement, all payments received as
proceeds of collateral, in a special bank account in a bank of secured party's
choice over which secured party alone shall have power of withdrawal. The funds
in said account shall secure the obligation. Secured party is authorized to make
any indorsement in debtor's name and behalf. Pending such deposit, debtor shall
not mingle any such payments with any of debtor's other funds or property, but
will hold them separate and upon an express trust for secured party. Secured
party may from time to time apply the whole or any part of the funds in the
special account against the obligation.

records covering the collateral. Debtor immediately will mark all books and
records with an entry showing the assignment of all accounts in collateral to
secured party and secured party is hereby given the right to audit the books and
records of debtor relating to collateral at any time and from time to time.

        (m) Disposition. If disposition of any collateral gives rise to an
account, chattel paper or instrument, debtor immediately shall notify secured
party, and upon request of secured party shall assign or indorse the same to
secured party. No collateral may be sold, leased, manufactured, processed or
otherwise disposed of by debtor in any manner without the prior written consent
of secured party, except inventory sold, leased, manufactured, processed or
consumed in the ordinary course of business.

        (n) Accounts. Each account in collateral will represent the valid and
legally enforceable obligation of third parties.

        (o) Location. Debtor shall give secured party written notice of each
office of debtor in which records of debtor pertaining to accounts in collateral
are kept, and of any change of any such location. If no such notice is given,
all records of debtor pertaining to accounts and all inventory are and shall be
kept at debtor's address shown above.

        (p) Changes. Debtor will notify secured party immediately of any
material change in the collateral, of a change in any manner warranted or
represented by debtor in this agreement or furnished to secured party, and of
any event of default.

        (q) Use/Removal. Debtor will not use the collateral illegally or permit
the collateral to be affixed to real or personal property without the written
consent of secured party. Debtor will keep all collateral at debtor's address
shown above.

        (r) Possession. If the collateral is chattel paper, documents,
instruments or investment securities or other instruments, secured party may
deliver a copy of this agreement to the broker or seller thereof, or any person
in possession thereof, and such delivery shall constitute notice to such person
of secured party's security interest therein and shall constitute debtor s
instruction to such person to deliver to secured party certificates or other
evidence of the same as
<PAGE>

soon as available. Debtor will deliver all investment securities and other
instruments, documents and chattel paper which are part of the collateral and in
debtor's possession to the secured party immediately, or if hereafter acquired,
immediately following acquisition, appropriately indorsed to secured party's
order or with appropriate executed powers. Debtor waives presentment, demand,
notice of dishonor, protest, and all other notices with respect thereof.

        (s) Chattel Paper. Debtor has perfected or will perfect a security
interest by means satisfactory to secured party in goods covered by chattel
paper in collateral.

        (t)  Intentionally left blank.

        (u) Change of Name. Without the written consent of secured party, debtor
shall not change its name or the state of its incorporation.

        (v) Power of Attorney. Debtor appoints secured party debtor's attorney-
in-fact with full power in debtor's name and behalf to do every act which debtor
is obligated to do or may be required to do hereunder; however, nothing in this
paragraph shall be construed to obligate secured party to take any action
hereunder.

        (w) Waivers.  Debtor waives notice of the creation, advance, increase,
existence, extension or renewal of, and of any indulgence with respect to, the
obligation; waives presentment, demand, notice of dishonor, and protest; waives
notice of the amount of the obligation outstanding at any time, notice of any
change in financial condition of any person liable for the obligation or any
part thereof, and all other notices respecting the obligation; and agrees that
maturity of the obligation and any part thereof may be accelerated, extended or
renewed one or more times by secured party in its discretion, without notice to
debtor.

        (x) Other Parties/Collateral.  No renewal or extension of or any other
indulgence with respect to the obligation or any part thereof, no release of any
security, no release of any person (including any maker, indorser, guarantor or
surety) liable on the obligation, no delay in enforcement of payment, and no
delay or omission or lack of diligence or care in exercising any right or power
with respect to the obligation or any security therefor or guaranty thereof or
under this agreement shall in any manner impair or affect the rights of secured
party under the law, hereunder, or under any other agreement pertaining to the
collateral. Secured party need not file suit or assert a claim for personal
judgment against any person for any part of the obligation or seek to realize
upon any other security for the obligation before foreclosing upon the
collateral for the purpose of paying the obligation.  Debtor waives any right to
the benefit of or to require or control application of any other security or
proceeds thereof, and agrees that secured party shall have no duty or obligation
to debtor to apply to the obligation any such other security or proceeds
thereof.

    8.  Rights and Powers of Secured Party.

        (a) General. Secured party before or after default and without liability
to debtor may: obtain from any person information regarding debtor or debtor's
business, which
<PAGE>

information any such person also may furnish without liability to debtor;
require debtor to give possession or control of any collateral to secured party;
indorse as debtor's agent any instruments, documents or chattel paper in
collateral or representing proceeds of collateral; contact account debtors
directly to verify information furnished by debtor; release collateral in its
possession to any debtor, temporarily or otherwise; reject as unsatisfactory any
property hereafter offered by debtor as collateral; set standards from time to
time to govern what may be used as after acquired collateral, designate, from
time to time, a certain percent of the collateral as the loan value and require
debtor to maintain the obligation at or below such figure; take control of funds
generated by the collateral and use same to reduce any part of the obligation.
Secured party shall not be liable for failure to collect any account or
instrument, or for any act or omission on the part of the secured party, its
officers, agents or employees, except willful misconduct. The foregoing rights
and powers of secured party will be in addition to, and not a limitation upon,
any rights and powers of secured party given by law, elsewhere in this
agreement, or otherwise.

        (b) Convertible Securities. Secured party may present for conversion any
instrument or investment security in collateral which is convertible into any
other instrument or investment or a combination thereof and cash, but secured
party shall not have any duty to present for conversion any instrument in
collateral unless it shall have received from debtor detailed written
instructions to that effect at a time reasonably far in advance of the final
conversion date to make such conversion possible.

    9.  Default.

        (a) Events of Default.  The following are events of default hereunder:

            (i) default in the timely payment or the performance of any part of
the obligation or in performance or observance of the terms and conditions
herein;

            (ii) any warranty, representation or statement made or furnished to
secured party herein, heretofore, or hereafter proves to have been false in any
material respect when made or furnished;

            (iii) acceleration of the maturity of debt of debtor to any other
person;

            (iv) substantial change in any fact warranted or represented in this
agreement or in any other agreement between debtor and secured party or in any
statement, schedule, or other writing furnished in connection therewith;

            (v) loss, theft, destruction or encumbrance or sale or transfer of
any collateral in violation hereof, or substantial damage to any collateral;

            (vi) dissolution, merger or consolidation, termination of existence,
insolvency or business failure of debtor; commencement of proceedings for the
appointment of a receiver for any property of debtor, or commission of an act of
bankruptcy by debtor; commencement of any proceeding under any bankruptcy or
insolvency law by or against debtor
<PAGE>

(or any corporate action shall be taken to effect same), or any partnership of
which debtor is a partner or by or against any person liable upon the obligation
or any part thereof, or liable upon collateral;

            (vii) levy on, seizure or attachment of any property of debtor; or

            (viii)  a judgment against debtor becomes final.

        (b) Remedies. When an event of default occurs, and at any time
thereafter, secured party without notice or demand may declare the obligation in
whole or in part immediately due and may enforce payment of the same and
exercise any rights under the UCC, rights and remedies of secured party under
this agreement, or otherwise. Secured party may require debtor to assemble the
collateral and make it available to secured party at a place which is reasonably
convenient to both parties. Unless the collateral is perishable or threatens to
decline speedily in value or is of a type customarily sold on a recognized
market, secured party will give debtor reasonable notice of the time and place
of any public sale thereof or of the time after which any private sale or other
intended disposition thereof is to be made. Expenses of retaking, holding,
preparing for sale, selling, leasing or the like shall include secured party's
reasonable attorney's fees. Secured party shall be entitled to immediate
possession of all books and records evidencing any accounts or general
intangibles or pertaining to chattel paper covered by this agreement and shall
have the authority to enter upon any premises upon which any of the same, or any
collateral, may be situated and to remove the same therefrom without liability.
Secured party may surrender any insurance policies in collateral and receive the
unearned premium thereon. Debtor shall be entitled to any surplus and shall be
liable to secured party for any deficiency. The proceeds of any disposition
after default available to satisfy the obligation shall be applied to the
obligation in such order and in such manner as secured party in its discretion
shall decide. If, in the opinion of secured party, there is any question that a
public sale or distribution of any collateral will violate any state or federal
securities law, secured party (i) may offer and sell securities privately to
purchasers who will agree to take them for investment purposes and not with a
view to distribution and who will agree to imposition of restrictive legends on
the certificates representing the security, or (ii) may sell such securities in
an intrastate offering under Section 3(a)(11) of the Securities Act of 1933, and
any sale so made in good faith by secured party shall be deemed to be
"commercially reasonable."

    10. General.

        (a) Parties Bound.  Secured party's rights hereunder shall inure to the
benefit of its successors and assigns, and in the event of any assignment or
transfer of any of the obligation or the collateral, secured party thereafter
shall be fully discharged from any responsibility with respect to the collateral
so assigned or transferred, but secured party shall retain all rights and powers
hereby given with respect to any of the obligation or collateral not so assigned
or transferred.  All representations, warranties and agreements of debtor if
more than one are joint and several, and all shall be binding upon the personal
representatives, heirs, successors and assigns of debtor.
<PAGE>

        (b) Waiver. No delay of secured party in exercising any power or right
shall operate as a waiver thereof; nor shall any single or partial exercise of
any power or right preclude other or further exercise thereof or the exercise of
any other power or right. No waiver by secured party of any right hereunder or
of any default by debtor shall be binding upon secured party unless in writing,
and no failure by secured party to exercise any power or right hereunder or
waiver of any default by debtor shall operate as a waiver of any other or
further exercise of such right or power or of any further default.

        (c) Agreement Continuing.  This agreement shall constitute a continuing
agreement, applying to all future as well as existing transactions, whether or
not of the character contemplated at the date of this agreement, and if all
transactions between secured party and debtor shall be closed at any time shall
be equally applicable to any new transactions thereafter.  Provisions of this
agreement, unless by their terms exclusive, shall be in addition to other
agreements between the parties.

        (d) Definitions. Unless the context indicates otherwise, definitions in
the UCC apply to words and phrases in this agreement; if UCC definitions
conflict, Chapter 9 definitions apply.

        (e) Notice. Notice shall be deemed reasonable if mailed postage prepaid
at least 5 days before the related action (or if the UCC elsewhere specifies a
longer period, such longer period) to the address of debtor given above.

        (f) Interest. No agreement relating to the obligation shall be construed
to be a contract for or to authorize charging or receiving, or require the
payment or permit the collection of, interest at a rate or in an amount above
that authorized by law. Interest payable under any agreement above that
authorized by law shall be reduced automatically to the highest amount permitted
by law. This provision shall override and supersede all other provisions of any
agreement relating to the obligation.

        (g) Modifications. No provision hereof shall be modified or limited
except by a written agreement expressly referring hereto and to the provisions
so modified or limited and signed by the debtor and secured party, nor by course
of conduct, usage of trade, or by the law merchant.

        (h) Severability. The unenforceability of any provision of this
agreement shall not affect the enforceability or validity of any other
provision.

        (i) Gender and Number. Where appropriate, the use of one gender shall be
construed to include the others or any of them, and the singular number shall be
construed to include the plural, and vice versa.

        (j) Applicable Law. This agreement shall be construed according to the
laws of Texas.

        (k) Financing Statement. A carbon, photographic or other reproduction of
this agreement or any financing statement covering the collateral shall be
sufficient as a financing statement.

                          CERTIFICATE OF DESIGNATION

                     SERIES J CONVERTIBLE PREFERRED STOCK



     HENRY W. SULLIVAN and JOHN F. REILLY do hereby certify that they are the
Chief Executive Officer and Secretary, respectively, of NORTH AMERICAN
TECHNOLOGIES GROUP, INC., a Delaware corporation (hereinafter referred to as the
"Corporation"); that, pursuant to the Corporation's Certificate of Incorporation
and Section 151 of the Delaware General Corporation Law, the Board of Directors
of the Corporation adopted the following resolutions on _______________, 2001:

     WHEREAS, the Corporation has determined to designate a new Series J
Convertible Preferred Stock pursuant to the authority granted in its Certificate
of Incorporation and Section 151 of the Delaware General Corporation Law.

     NOW, THEREFORE, the Corporation's Series J Preferred shall have the rights
and preferences set forth below:

     SERIES J CONVERTIBLE PREFERRED STOCK.  There is hereby created a series of
preferred stock designated as Convertible Preferred Stock, Series J (the "Series
J Preferred"), which will consist of ________ shares.  The Series J Preferred
shall have the preferences, voting powers, relative, participating, optional or
other special rights and privileges, and the qualifications, limitations and
restrictions as provided below:

     1.  DIVIDENDS AND DISTRIBUTIONS.

         (a) Beginning on the date of the issuance of the Series J Preferred,
the holders of shares of Series J Preferred shall be entitled to receive annual
dividends at a rate of 5% per annum of the Stated Value (as defined below) when,
as and if declared by the Board of Directors and not otherwise. The Board of
Directors may only declare such dividends, if at all, when the Corporation shall
have earned a net profit (exclusive of any gains realized on its resale of
certain securities acquired by the Corporation in conjunction with a Securities
Purchase Agreement dated October 2, 2001) of at least $1,000,000 during the
prior fiscal year and such dividends may be declared, if at all, and paid only
to the extent of one-half of the amount of the Corporation's net profit for the
prior fiscal year, less any gain on the sale of the securities described in this
sentence. Dividends shall be non-cumulative and shall be prior and in preference
to any declaration or payment of any dividend or other distribution on the
Corporation's common stock, par value $0.001 per share ("Common Stock") to the
extent specified in Section 1(b). The
<PAGE>

dividends on the Series J Preferred, if declared, shall be payable within 45
days of declaration (each a "Dividend Date"), except that if any such date is a
Saturday, Sunday or legal holiday (a "Non-Business Day") then such dividend
shall be payable on the next day that is not a Saturday, Sunday or legal holiday
on which banks in the State of Delaware are permitted to be closed (a "Business
Day") to holders of record as they appear on the stock books of the Corporation
on the applicable record date, which shall be not more than 60 nor less than 10
days preceding the payment date for such dividends, as fixed by the Board of
Directors (the "Record Date"). The dividends on the Series J Preferred shall be
payable only when, as and if declared by the Board of Directors out of funds
legally available therefor. Dividends, if declared, shall be payable in cash,
provided, however, that at the option of the Corporation, dividends may be paid
upon conversion of the Series J Preferred Stock, as provided in Section 3
hereof, in cash or in such number of shares of the Corporation's Common Stock
equal to the aggregate amount of the accrued dividends divided by the Conversion
Price (as defined herein). No dividends shall accrue on the Series J Preferred
unless and except to the extent, if any, the dividends are declared. The amount
of dividends payable for any period that is shorter or longer than a full year
shall be computed on the basis of a 360-day year of twelve 30-day months.

         (b) In the event the Board of Directors wishes to declare and pay a
dividend to the holders of the Corporation's Common Stock, it shall, prior to
the declaration and payment of any such dividend, be required to (i) declare and
pay one year's annual dividend to the holders of the Series J Preferred, if it
has not already done so during the year in which the dividend on the Common
Stock is desired to be paid, and (ii) pay the full amount of all declared and
unpaid dividends on the Series J Preferred as of such date.

     2.  LIQUIDATION RIGHTS.  In the event of any liquidation, dissolution or
winding up of the Corporation, whether voluntary or involuntary, distributions
shall be made to the holders of Series J Preferred in respect of such Series J
Preferred, in the following manner:

         (a) SERIES J PREFERRED LIQUIDATION PREFERENCE.  The holders of the
Series J Preferred shall be entitled to be paid all amounts payable hereunder on
account of the liquidation of the Corporation, prior to the payment of any
amounts on account of the liquidation of the Corporation to the holders of any
other class or Series of preferred stock or common stock of the Corporation, out
of the assets of the Corporation available for distribution to holders of its
capital stock, a preferred distribution as set forth below.  The liquidation
preference payable to the holders of the Series J Preferred shall be equal to
the sum of (i) $1.00 per share (the "Stated Value"), as appropriately adjusted
to reflect any stock split, stock dividend, combination, recapitalization and
the like (collectively a "Recapitalization") of the Series J Preferred, plus
(ii) all declared but unpaid dividends (including any interest accrued thereon
calculated through the date of liquidation) (the sum of (i) and (ii) being
collectively referred to as the "Series J Liquidation Preference"). If, upon the
occurrence of a liquidation, dissolution or winding up, the assets and funds
thus distributed among the holders of the Series J Preferred shall be
insufficient to permit the payment to such holders of their full liquidation
preferences, then the entire assets and funds of the Corporation legally
available for distribution to the holders of capital stock shall be distributed,
pari passu, to the holders of the Series J Preferred.
<PAGE>

         (b) REMAINING ASSETS.  If assets are remaining after payment in full
of the Series J Liquidation Preference to all holders of the Series J Preferred,
then the holders of any other class or series of Preferred Stock, if any, shall
be entitled to their respective preferential amounts on liquidation, and
thereafter the holders of the Common Stock shall be entitled to share ratably in
all such remaining assets and surplus funds based on the number of shares of
Common Stock held by each.

         (c) VALUATION OF SECURITIES AND PROPERTY.  In the event the
Corporation proposes to distribute assets other than cash in connection with any
liquidation, dissolution or winding up of the Corporation, the value of the
assets to be distributed to the holders of shares of Series J Preferred shall be
determined in good faith by the Board of Directors.  Notwithstanding the
foregoing, any securities so distributed shall be valued as follows:

             (i) If the securities are traded on a national securities
     exchange or the NASDAQ National Market System ("NASDAQ/NMS") or actively
     traded over-the-counter (other than NASDAQ/NMS), the value of such
     securities shall be deemed to be the average of the security's closing
     prices on such exchange or NASDAQ/NMS over the thirty (30) calendar day
     period ending three (3) days prior to the distribution; and

             (ii) If there is no active public market, the value shall be the
     fair market value thereof as determined in good faith by the Board of
     Directors.

The method of valuation of securities subject to an investment letter or other
restrictions on free marketability shall be adjusted to make an appropriate
discount from the market value determined as above in clauses (i) or (ii) to
reflect the fair market value thereof as determined in good faith by the Board
of Directors.

     3.  CONVERSION.  The Series J Preferred is subject to conversion at the
times and on the terms set forth in this Section 3:

         (a)  RIGHT OF HOLDER TO CONVERT.

              (i) Election to Convert. Each share of Series J Preferred shall
initially be convertible, at the option of the holder thereof, at any time at
the principal office of the Corporation or any transfer agent for the Series J
Preferred, into one (1) fully paid and nonassessable share of Common Stock.
Upon such a conversion, the aggregate amount of any declared but unpaid
dividends (including any interest, if any, accrued thereon calculated as of the
date of conversion) on the Series J Preferred shall also be converted into
Common Stock at the Conversion Price.  The Conversion Price shall be equal to
the value of a share of Common Stock on the date of issuance of the Series J
Preferred, which value shall be calculated as follows:

              (A) If the Common Stock is traded on a national securities
     exchange or the NASDAQ National Market System ("NASDAQ/NMS") or actively
     traded over-the-counter (other than NASDAQ/NMS), the value of such
     securities shall be deemed to be the average of the security's closing
     prices on such exchange or NASDAQ/NMS or in
<PAGE>

     over-the-counter trading over the thirty (30) calendar day period ending
     three (3) days prior to the issuance date; and

              (B) If there is no active public market in the Common Stock, the
     value shall be the fair market value thereof as determined in good faith by
     the Board of Directors.

              (ii) Mechanics of Conversion. Before a holder of Series J
Preferred shall be entitled to convert the same into shares of Common Stock and
to receive certificates therefor, such holder shall surrender the certificate or
certificates therefor, duly endorsed, at the principal office of the Corporation
or of any transfer agent for the Series J Preferred, and shall give written
notice to the Corporation at such office that such holder elects to convert the
same. The Corporation shall, as soon as practicable after such delivery, issue
and deliver to such holder of the Series J Preferred, a certificate or
certificates for the number of shares of Common Stock to which such holder shall
be entitled as aforesaid. Such conversion shall be deemed to have been made
immediately prior to the close of business on the date of such surrender of the
shares of the Series J Preferred to be converted, and the holder or holders
entitled to receive the shares of Common Stock issuable upon such conversion
shall be treated for all purposes as the record holder or holders of such shares
of Common Stock on such date.

         (b)  ADJUSTMENTS.

              (i) Subdivisions, Combinations, or Consolidations of Common Stock.
In the event the outstanding shares of Common Stock shall be subdivided,
combined or consolidated, by stock split, reverse stock split, stock dividend,
combination or like event, into a greater or lesser number of shares of Common
Stock, the number of shares of Common Stock into which each share of Series J
Preferred may be converted and the Conversion Price in effect immediately prior
to such subdivision, combination, consolidation or stock dividend shall,
concurrently with the effectiveness of such subdivision, combination or
consolidation, be proportionately adjusted.

              (ii) Reclassifications.  In the case, at any time after the date
hereof, of any capital reorganization or any reclassification of the stock of
the Corporation (other than as a result of a stock dividend or subdivision,
split-up or combination of shares), or the consolidation or merger of the
Corporation with or into another person (other than a consolidation or merger in
which the Corporation is the continuing entity and which does not result in any
change in the Common Stock), the shares of the Series J Preferred shall, after
such reorganization, reclassification, consolidation or merger be convertible
into the kind and number of shares of stock or other securities or property of
the Corporation or otherwise to which such holder would have been entitled if
immediately prior to such reorganization, reclassification, consolidation or
merger such holder had converted its shares of the Series J Preferred Stock into
Common Stock.

              (iii)  Certificate as to Adjustments.  Upon the occurrence of each
adjustment or readjustment of the number of shares of Common Stock into which
each share of Series J Preferred may be converted and the Conversion Price
pursuant to this Section 3, the Corporation at its expense shall promptly
compute such adjustment or readjustment in accordance with the terms hereof and
furnish to each holder of the Series J Preferred so adjusted a certificate
<PAGE>

setting forth such adjustment or readjustment and showing in detail the facts
upon which such adjustment or readjustment is based.  The Corporation shall,
upon the written request at any time of any holder of a the Series J Preferred,
furnish or cause to be furnished to such holder a like certificate setting forth
(i) such adjustments and readjustments, (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 property which at the time would be received upon the conversion of the
Series J Preferred.

         (c) STATUS OF CONVERTED STOCK.  In case any shares of the Series J
Preferred shall be converted pursuant to Section 3 hereof, the shares so
converted shall, at the option of the Corporation, be canceled, and, if not
canceled, shall not be reissuable as shares of Series J Preferred but shall be
part of the authorized but unissued capital stock of the Corporation.

         (d) MISCELLANEOUS.  All calculations under this Section 3 shall be
made to the nearest cent or to the nearest whole share, as the case may be.

         (e) NO IMPAIRMENT.  The Corporation will not, through any
reorganization, recapitalization, transfer of assets, consolidation, merger,
dissolution, issue or sale of securities or any other voluntary action, avoid or
seek to avoid the observance or performance of any of the terms to be observed
or performed hereunder by the Corporation, but will at all times in good faith
assist in the carrying out of all the provisions of this Section 3 and in the
taking of all such action as may be necessary or appropriate in order to protect
the conversion rights of the holders of Series J Preferred against impairment.

         (f) RESERVATION OF STOCK ISSUABLE UPON CONVERSION.  The Corporation
shall at all times reserve and keep available out of its authorized but unissued
shares of Common Stock, solely for the purpose of effecting the conversion of
the shares of the Series J Preferred, such number of its shares of Common Stock
as shall from time to time be sufficient to effect the conversion of all
outstanding shares of the Series J Preferred.  If at any time the number of
authorized but unissued shares of Common Stock shall not be sufficient to effect
the conversion of all then outstanding shares of the Series J Preferred, the
Corporation will take such corporate action as may, in the opinion of its
counsel, be necessary to increase its authorized but unissued shares of Common
Stock to such number of shares as shall be sufficient for such purpose.

     4.  VOTING RIGHTS.  Except as otherwise required by law, the holders
of all of the Series J Preferred issued and outstanding, in the aggregate, shall
be entitled to the number of votes equal to the number of shares of Common Stock
into which shares of Series J Preferred are convertible on any record date, or,
if no such record date is established, at the date such vote is taken or any
written consent of stockholders is solicited, such votes to be counted together
with all other shares of stock of the Corporation having general voting power
and not separately as a class.  Fractional votes by the holders of the Series J
Preferred shall not, however, be permitted, and any fractional voting rights
shall (after aggregating all shares into which shares of Series J Preferred held
by each holder could be converted) be rounded to the nearest whole number.

     5. NOTICES OF RECORD DATE. In the event of any taking by the Corporation of
a record of the holders of any class of securities for the purpose of
determining the holders thereof who are entitled to receive any dividend or
other distribution, any right to subscribe for,
<PAGE>

purchase or otherwise acquire any shares of stock of any class or any other
securities or property, or to receive any other right, the Corporation shall
mail to each holder of the Series J Preferred, at least twenty (20) days prior
to the date specified therein, a notice specifying the date on which any such
record is to be taken for the purpose of such dividend, distribution or right,
and the amount and character of such dividend distribution or right.

     6. NOTICES. Any notice required by the provisions of the Certificate to be
given to the holders of the Series J Preferred shall be deemed given when
deposited in the United States mail, postage prepaid, and addressed to each
holder of record at his or her address appearing on the books of the
Corporation, or upon actual receipt when personally delivered or sent by
overnight or other courier delivery.

     7.  PROTECTIVE PROVISIONS.  So long as any shares of the Series J Preferred
are outstanding, the Corporation shall not, without first obtaining the approval
of the holders of at least a majority in interest of the Series J Preferred then
outstanding, voting as a separate class, take any action that:
