 STATEMENT OF
AGREEMENT 
  
 In consideration of the premises and the mutual
covenants and agreements set forth herein, and for other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the Parties, intending to be legally bound, agree as follows: 

 1. Agreements of Lender. 
  
 (a) Ownership. The Lender represents and warrants that, as of the date hereof, (i) the Lender is the
sole legal and beneficial owner of the entire amount of the debt outstanding under the Construction Loan Agreement (the “Debt”) and all related claims, rights, powers and causes of action arising out of or in connection with
or otherwise relating to such Debt (the “Claims”), in each case free and clear of all claims, liens and encumbrances and (ii) the Lender has full power and authority to vote on and consent to such matters concerning such Debt
and Claims and to exchange, assign and transfer such Debt and Claims. 
  
 (b) Agreement to Forbear. The Lender agrees that until this Agreement has been terminated in accordance with Section 3, it shall not, with respect to any of the Pending Defaults (i) take any action or
otherwise pursue any right or remedy under (A) the Construction Loan Agreement or (B) any of the Loan Documents, or (ii) initiate, or have initiated on its behalf, any litigation or proceeding of any kind with respect to the Debt or Claims other
than to enforce this Agreement. 
  
 (c)
Agreement to Defer Missed Principal Payments. Lender hereby agrees that the payments of principal that would otherwise have been due and payable on April 1, 2005, July 1, 2005, and October 1, 2005, under the Construction Loan Agreement shall
be deferred until, and shall be due and payable on, January 1, 2006. 
  
 2. Agreements of the Borrower and the Borrower Affiliates. The Borrower and the Borrower Affiliates hereby agree: 
  
 (a) that the Construction Loan Agreement (as amended to date as described in the preamble to this Agreement) and the Loan Documents remain
in full force and effect and that the Borrower and the Borrower Affiliates have no defense, offset or counterclaim against the Lender that would prevent the Lender from enforcing the Construction Loan Agreement or any Loan Document in accordance
with its terms; 
  
 (b) that upon execution of
this Agreement, at Lender’s option, TieTek shall execute a promissory note for the interest payment that was due on April 1, 2005 in the form attached hereto as Exhibit A-1 and on July 1, 2005 and October 1, 2005, at Lender’s option,
TieTek shall execute a promissory note for each interest payment due on that date in the forms attached hereto on Exhibit A-2 and A-3, respectively;

exchange for a combination of securities deemed fair by the investment advisor and acceptable to other investment groups; 
  
 (d) to select special counsel and select, by no later than May 25, 2005, an investment banker to determine the feasibility of refinancing,
with another lender, the Construction Loan, and/or to determine the feasibility of Borrower and the Borrower Affiliates obtaining, a bridge loan, a working capital loan or a permanent loan, and if it is feasible to do so, to determine the terms and
conditions under which each type of loan may be obtained. It is the Borrower’s and the Borrower Affiliates’ intent that the investment banker selected by the Borrower and the Borrower Affiliates shall be one that is experienced in matters
such as obtaining financing for manufacturing facilities, financing for bridge and working capital loans and refinancing of loans such as the Construction Loan; 

 (e) to solicit accredited investors, from a group of large shareholders, (generally that

achieve stabilization of its manufacturing processes;

alternative refinancing of the Construction Loan; 
  
 (g) to obtain a commitment for additional financing on or before July 30, 2005; 
  
 (h) on or before May 25, 2005, the Borrower and the Borrower Affiliates shall engage the services of one or more consultants for the

with a completion date of July 1, 2005, with the Consultant and the Company providing interim comments with respect to such matters and timely development of a strategic plan to effect the foregoing; 
  
 (i) to provide weekly, beginning May 13, 2005, Lender the
same or substantially similar information that Borrower and the Borrower Affiliates provide to the members of its Board of Directors and to its management including without limitation, specific performance reports or measurements, financial plans
and budgets, and any other information reasonably requested by Lender. Such reports shall be substantially in the form of the reports and items set forth on Exhibit B attached hereto and made a part hereof and discussed in a weekly conference call
with Lender’s representative as Borrower works to achieve its operating goals; 
  
 (j) to have certain members, as determined by Lender, of Borrower’s and the Borrower Affiliates’ management and/or board
members, to meet with Lender, but not more than frequently than once a month, to discuss and review Borrower’s and the Borrower Affiliates’ business affairs and plans provided, however, that in the event Lender has questions or concerns
regarding the status of Borrower and the Borrower Affiliates, the Lender may request a conference call with Borrower and the Borrower Affiliates which shall occur within 48 hours of such request; and

 PROMISSORY NOTE 
  

					
	 $407,944.45
	 	 Dallas, Texas
	 	 April 1, 2005

  
 FOR VALUE RECEIVED,
the undersigned, TIETEK, INC., a Delaware corporation (herein called “Maker”), hereby promises to pay to the order of OPUS 5949 LLC, a Texas limited liability company (herein sometimes called “Payee”), the principal
sum of Four Hundred Seven Thousand Nine Hundred Forty-four and 45/100 Dollars ($407,944.45), or so much thereof from time to time outstanding as shall be advanced, with interest on the unpaid balance thereof from date hereof until maturity at the
rate or rates hereinafter provided, both principal and interest payable as hereinafter provided in lawful money of the United States of America at the offices of Payee at 5949 Sherry Lane, Suite 1900, Dallas, Texas 75225, or at such other place
within Dallas County, Texas, as from time to time may be designated by the holder of this Note. 
  
 As herein provided the unpaid Principal Amount of this Note (or portions thereof) from time to time outstanding shall bear interest prior to maturity at
the Applicable Rate, provided that in no event shall the Applicable Rate exceed the Maximum Rate. Notwithstanding the foregoing, if at any time the Applicable Rate exceeds the Maximum Rate, the rate of interest payable under this Note shall be
limited to the Maximum Rate, but any subsequent reductions in the Applicable Rate shall not reduce the Applicable Rate below the Maximum Rate until the total amount of interest accrued on this Note equals the total amount of interest which would
have accrued at the Applicable Rate if the Applicable Rate had at all times been in effect. 
  
 As used in this Note, the following terms shall have the meanings indicated opposite them: 
  
 “Applicable Rate.” The Prime Rate (as hereinafter defined) plus 700 basis points. It being understood and agreed that the
Applicable Rate shall increase or decrease, as the case may be, from time to time as of the effective date of each change in the Prime Rate. 
  
 “Default Rate.” The Default Rate shall be the Maximum Rate. 
  
 “Loan.” The $407,944.45 loan to be made to Maker by Payee and evidenced hereby. 

 
 “Maturity Date.” January 1, 2006

  
 “Maximum Rate.” The maximum
interest rate permitted under applicable law, it being understood that, if applicable law provides for a ceiling under Chapter 301, Subchapter A of the Texas Credit Title (as may be amended from time to time), such ceiling shall be the
“weekly” ceiling. 
  
 “Prime
Rate.” The annual rate of interest identified as the “prime rate” in the “Money Rate” column published in The Wall Street Journal. If the published prime rate is expressed on the applicable date as a range, the
Prime Rate for purposes of this Note will be the average between the high and law of that range. If The Wall Street Journal ceases to publish a prime rate, Lender may refer to another similar source to identify the prime rate on corporate
loans at large United States money center commercial banks and apply that rate. 

 “Principal Amount.” That portion of the Loan evidenced hereby as is from
time to time outstanding. 
  
 Maker shall have the right to prepay
this Note, in whole or in part, without premium or penalty upon written notice thereof given to Payee at least fifteen (15) days prior to the date to be fixed therein for prepayment, and upon the payment of all accrued interest on the amount prepaid
(and any interest which has accrued at the Default Rate, if applicable, and other sums that may be payable hereunder) to the date so fixed. 
  
 The Principal Amount and accrued interest shall be due and payable on the Maturity Date. 
  
 Notwithstanding anything to the contrary contained in this Note, at the option of the holder of this Note and upon notice to
the Maker at any time after the occurrence of a default hereunder, from and after such notice and during the continuance of such default, the unpaid principal of this Note from time to time outstanding and all past due installments of interest
shall, to the extent permitted by applicable law, bear interest at the Default Rate, provided that in no event shall such interest rate be more than the Maximum Rate. 
  
 All interest accruing under this Note shall be calculated on the basis of a 360-day year applied to the actual number of
days in each month. The Maker shall make each payment which it owes hereunder not later than twelve o’clock, noon, Dallas, Texas, time, on the date such payment becomes due and payable (or the date any voluntary prepayment is made), in
immediately available funds. Any payment received by the Payee after such time will be deemed to have been made on the next following business day. As used herein, the term “business day” shall mean a day on which commercial banks are open
for business with the public in Dallas, Texas. 
  
 This Note has
been executed and delivered as a payment in kind with respect to the interest payment that is otherwise due and payable on April 1, 2005 pursuant to the terms of that certain promissory note dated February 5, 2004 in the original principal amount of
$14,000,000 (the “Original Loan”) and executed by TieTek, LLC and its affiliates North American Technologies Group, Inc. and TieTek Technologies, Inc. as Maker in favor of Payee and is secured by that certain Deed of Trust, Security
Agreement and Patent Security Agreement, each dated February 2, 2004, and executed in connection with the Original Loan. 
  
 Payee and Maker intend in the execution of this Note and all other instruments now or hereafter securing this Note to contract in strict compliance with
applicable usury law. In furtherance thereof, Payee and Maker stipulate and agree that none of the terms and provisions contained in this Note, or in any other instrument executed in connection herewith, shall ever be construed to create a contract
to pay for the use, forbearance or detention of money, interest at a rate in excess of the Maximum Rate; neither Maker nor any guarantors, endorsers or other parties now or hereafter becoming liable for payment of this Note shall ever be obligated
or required to pay interest on this Note at a rate in excess of the Maximum Rate that may be lawfully charged under applicable law, and the provisions of this paragraph shall control over all other provisions of this Note and any other instruments
now or hereafter executed in connection herewith which may be in apparent conflict herewith. Payee, including each holder of this Note, expressly disavows any intention to charge or collect excessive unearned interest or finance charges in the event
the maturity of this Note is accelerated. If the maturity of this Note shall be accelerated for any reason or if the Principal Amount is paid prior to the end of the term of this Note, and as a result thereof the interest received for the actual
period of existence of the Loan exceeds the amount of interest that would have accrued at the Maximum Rate, the Payee or other 

 
holder of this Note shall, at its option, either refund to Maker the amount of such excess or credit the amount of such excess against the Principal Amount
and thereby shall render inapplicable any and all penalties of any kind provided by applicable law as a result of such excess interest. In the event that Payee or any other holder of this Note shall contract for, charge or receive any amounts and/or
any other thing of value which are determined to constitute interest which would increase the effective interest rate on this Note to a rate in excess of that permitted to be charged by applicable law, all such sums determined to constitute interest
in excess of the amount of interest at the lawful rate shall, upon such determination, at the option of the Payee or other holder of this Note, be either immediately returned to Maker or credited against the Principal Amount, in which event any and
all penalties of any kind under applicable law as a result of such excess interest shall be inapplicable. By execution of this Note, Maker acknowledges that it believes the Loan evidenced by this Note to be non-usurious and agrees that if, at any
time, Maker should have reason to believe that the Loan is in fact usurious, it will give the Payee or other holder of this Note notice of such condition and Maker agrees that the Payee or other holder shall have ninety (90) days in which to make
appropriate refund or other adjustment in order to correct such condition if in fact such exists. The term “applicable law” as used in this Note shall mean the laws of the state of Texas or the laws of the United States, whichever laws
allow the greater rate of interest, as such laws now exist or may be changed or amended or come into effect in the future. 
  
 Should the indebtedness represented by this Note or any part thereof be collected at law or in equity or through any bankruptcy, receivership, probate or
other court proceedings or if this Note is placed in the hands of attorneys for collection after default, Maker and all endorsers, guarantors and sureties of this Note jointly and severally agree to pay to the Payee or other holder of this Note in
addition to the principal and interest due and payable hereon reasonable attorneys’ and collection fees. 
  
 Maker and all endorsers, guarantors and sureties of this Note and all other persons obligated or to become obligated on this Note severally waive
presentment for payment, demand, notice of demand and of dishonor and nonpayment of this Note, notice of intention to accelerate the maturity of this Note, protest and notice of protest, diligence in collecting, and the bringing of suit against any
other party, and agree to all renewals, extensions, modifications, partial payments, releases or substitutions of security, in whole or in part, with or without notice, before or after maturity. 
  
 THIS NOTE AND THE PARTIES’ RIGHTS AND OBLIGATIONS HEREUNDER SHALL IN ALL
RESPECTS BE GOVERNED BY, AND CONSTRUED AND ENFORCED IN ACCORDANCE WITH, THE LAWS OF THE STATE OF TEXAS (WITHOUT GIVING EFFECT TO TEXAS’ PRINCIPLES OF CONFLICTS OF LAW) AND THE LAWS OF THE UNITED STATES APPLICABLE TO TRANSACTIONS IN SUCH STATE.
MAKER HEREBY IRREVOCABLY SUBMITS TO THE NON-EXCLUSIVE JURISDICTION OF ANY TEXAS OR FEDERAL COURT SITTING IN DALLAS, TEXAS OVER ANY SUIT, ACTION OR PROCEEDING ARISING OUT OF OR RELATING TO THIS NOTE AND MAKER HEREBY AGREES AND CONSENTS THAT, IN

 FOR VALUE RECEIVED,
the undersigned, TIETEK, INC., a Delaware corporation (herein called “Maker”), hereby promises to pay to the order of OPUS 5949 LLC, a Texas limited liability company (herein sometimes called “Payee”), the principal
sum of $                    
($                    ), or so much thereof from time to time outstanding as shall be advanced, with interest on the unpaid balance thereof
from date hereof until maturity at the rate or rates hereinafter provided, both principal and interest payable as hereinafter provided in lawful money of the United States of America at the offices of Payee at 5949 Sherry Lane, Suite 1900, Dallas,
Texas 75225, or at such other place within Dallas County, Texas, as from time to time may be designated by the holder of this Note. 
  
 As herein provided the unpaid Principal Amount of this Note (or portions thereof) from time to time outstanding shall bear interest prior to maturity at
the Applicable Rate, provided that in no event shall the Applicable Rate exceed the Maximum Rate. Notwithstanding the foregoing, if at any time the Applicable Rate exceeds the Maximum Rate, the rate of interest payable under this Note shall be
limited to the Maximum Rate, but any subsequent reductions in the Applicable Rate shall not reduce the Applicable Rate below the Maximum Rate until the total amount of interest accrued on this Note equals the total amount of interest which would
have accrued at the Applicable Rate if the Applicable Rate had at all times been in effect. 
  
 As used in this Note, the following terms shall have the meanings indicated opposite them: 
  
 “Applicable Rate.” The Prime Rate (as hereinafter defined) plus 700 basis points. It being understood and agreed that the
Applicable Rate shall increase or decrease, as the case may be, from time to time as of the effective date of each change in the Prime Rate. 
  
 “Default Rate.” The Default Rate shall be the Maximum Rate. 
  
 *The principal amount of this Promissory Note shall be equal to the interest accrued on the Original Loan for the period from April 1,
2005 through June 30, 2005, which would otherwise be due and payable on July 1, 2005. The interest shall be calculated at the Applicable Rate (as defined in the Original Loan) for the period from April 1, 2005 to May 9, 2005, inclusive, and
thereafter shall be calculated at the Default Rate (as defined in the Original Loan). 
  
 “Loan.” The
$                     loan to be made to Maker by Payee and evidenced hereby. 
  
 “Maturity Date.” January 1, 2006 
  
 “Maximum Rate.” The maximum interest rate
permitted under applicable law, it being understood that, if applicable law provides for a ceiling under Chapter 301, Subchapter A of the Texas Credit Title (as may be amended from time to time), such ceiling shall be the “weekly” ceiling.

  
 “Prime Rate.” The annual rate
of interest identified as the “prime rate” in the “Money Rate” column published in The Wall Street Journal. If the published prime rate 

	 	 
is expressed on the applicable date as a range, the Prime Rate for purposes of this Note will be the average between the high and law of that range. If
The Wall Street Journal ceases to publish a prime rate, Lender may refer to another similar source to identify the prime rate on corporate loans at large United States money center commercial banks and apply that rate.

  
 “Principal
Amount.” That portion of the Loan evidenced hereby as is from time to time outstanding. 
  
 Maker shall have the right to prepay this Note, in whole or in part, without premium or penalty upon written notice thereof given to Payee at least
fifteen (15) days prior to the date to be fixed therein for prepayment, and upon the payment of all accrued interest on the amount prepaid (and any interest which has accrued at the Default Rate, if applicable, and other sums that may be payable
hereunder) to the date so fixed. 
  
 The Principal Amount and
accrued interest shall be due and payable on the Maturity Date. 
  
 Notwithstanding anything to the contrary contained in this Note, at the option of the holder of this Note and upon notice to the Maker at any time after the occurrence of a default hereunder, from and after such notice and during the
continuance of such default, the unpaid principal of this Note from time to time outstanding and all past due installments of interest shall, to the extent permitted by applicable law, bear interest at the Default Rate, provided that in no event
shall such interest rate be more than the Maximum Rate. 
  
 All
interest accruing under this Note shall be calculated on the basis of a 360-day year applied to the actual number of days in each month. The Maker shall make each payment which it owes hereunder not later than twelve o’clock, noon, Dallas,
Texas, time, on the date such payment becomes due and payable (or the date any voluntary prepayment is made), in immediately available funds. Any payment received by the Payee after such time will be deemed to have been made on the next following
business day. As used herein, the term “business day” shall mean a day on which commercial banks are open for business with the public in Dallas, Texas. 
  
 This Note has been executed and delivered as a payment in kind with respect to the interest payment that is otherwise due
and payable on April 1, 2005 pursuant to the terms of that certain promissory note dated February 5, 2004 in the original principal amount of $14,000,000 (the “Original Loan”) and executed by TieTek, LLC and its affiliates North American
Technologies Group, Inc. and TieTek Technologies, Inc. as Maker in favor of Payee and is secured by that certain Deed of Trust, Security Agreement and Patent Security Agreement, each dated February 2, 2004, and executed in connection with the
Original Loan. 
  
 Payee and Maker intend in the execution of this
Note and all other instruments now or hereafter securing this Note to contract in strict compliance with applicable usury law. In furtherance thereof, Payee and Maker stipulate and agree that none of the terms and provisions contained in this Note,
or in any other instrument executed in connection herewith, shall ever be construed to create a contract to pay for the use, forbearance or detention of money, interest at a rate in excess of the Maximum Rate; neither Maker nor any guarantors,
endorsers or other parties now or hereafter becoming liable for payment of this Note shall ever be obligated or required to pay interest on this Note at a rate in excess of the Maximum Rate that may be lawfully charged under applicable law, and the
provisions of this paragraph shall control over all other provisions of this Note and any other instruments now or hereafter executed in connection herewith which may be in apparent conflict herewith. Payee, including each holder of this Note,

 
expressly disavows any intention to charge or collect excessive unearned interest or finance charges in the event the maturity of this Note is accelerated.
If the maturity of this Note shall be accelerated for any reason or if the Principal Amount is paid prior to the end of the term of this Note, and as a result thereof the interest received for the actual period of existence of the Loan exceeds the
amount of interest that would have accrued at the Maximum Rate, the Payee or other holder of this Note shall, at its option, either refund to Maker the amount of such excess or credit the amount of such excess against the Principal Amount and
thereby shall render inapplicable any and all penalties of any kind provided by applicable law as a result of such excess interest. In the event that Payee or any other holder of this Note shall contract for, charge or receive any amounts and/or any
other thing of value which are determined to constitute interest which would increase the effective interest rate on this Note to a rate in excess of that permitted to be charged by applicable law, all such sums determined to constitute interest in
excess of the amount of interest at the lawful rate shall, upon such determination, at the option of the Payee or other holder of this Note, be either immediately returned to Maker or credited against the Principal Amount, in which event any and all
penalties of any kind under applicable law as a result of such excess interest shall be inapplicable. By execution of this Note, Maker acknowledges that it believes the Loan evidenced by this Note to be non-usurious and agrees that if, at any time,
Maker should have reason to believe that the Loan is in fact usurious, it will give the Payee or other holder of this Note notice of such condition and Maker agrees that the Payee or other holder shall have ninety (90) days in which to make
appropriate refund or other adjustment in order to correct such condition if in fact such exists. The term “applicable law” as used in this Note shall mean the laws of the state of Texas or the laws of the United States, whichever laws
allow the greater rate of interest, as such laws now exist or may be changed or amended or come into effect in the future. 
  
 Should the indebtedness represented by this Note or any part thereof be collected at law or in equity or through any bankruptcy, receivership, probate or
other court proceedings or if this Note is placed in the hands of attorneys for collection after default, Maker and all endorsers, guarantors and sureties of this Note jointly and severally agree to pay to the Payee or other holder of this Note in
addition to the principal and interest due and payable hereon reasonable attorneys’ and collection fees. 
  
 Maker and all endorsers, guarantors and sureties of this Note and all other persons obligated or to become obligated on this Note severally waive
presentment for payment, demand, notice of demand and of dishonor and nonpayment of this Note, notice of intention to accelerate the maturity of this Note, protest and notice of protest, diligence in collecting, and the bringing of suit against any
other party, and agree to all renewals, extensions, modifications, partial payments, releases or substitutions of security, in whole or in part, with or without notice, before or after maturity. 
  
 THIS NOTE AND THE PARTIES’ RIGHTS AND OBLIGATIONS HEREUNDER SHALL IN ALL
RESPECTS BE GOVERNED BY, AND CONSTRUED AND ENFORCED IN ACCORDANCE WITH, THE LAWS OF THE STATE OF TEXAS (WITHOUT GIVING EFFECT TO TEXAS’ PRINCIPLES OF CONFLICTS OF LAW) AND THE LAWS OF THE UNITED STATES APPLICABLE TO TRANSACTIONS IN SUCH STATE.
MAKER HEREBY IRREVOCABLY SUBMITS TO THE NON-EXCLUSIVE JURISDICTION OF ANY TEXAS OR FEDERAL COURT SITTING IN DALLAS, TEXAS OVER ANY SUIT, ACTION OR PROCEEDING ARISING OUT OF OR RELATING TO THIS NOTE AND MAKER HEREBY AGREES AND CONSENTS THAT, IN
