 For the Purchase

 of 
 HQ SUSTAINABLE MARITIME INDUSTRIES, INC. 
 (A Delaware Corporation) 
  

	1.	Purchase Option. 

 THIS CERTIFIES THAT, in
consideration of $100.00 duly paid by or on behalf of                      (“Holder”) and other like holders, as registered owner of
this Purchase Option, to HQ Sustainable Maritime Industries, Inc. (“Company”), Holder is entitled, at any time or from time to time at or after             , 2008
(“Commencement Date”), and at or before 5:00 p.m., Eastern Time,             , 2012 (“Expiration Date”), but not thereafter, to subscribe for, purchase and
receive, in whole or in part, up to four hundred and fifty thousand (450,000) shares of Common Stock of the Company, $.001 par value (“Common Stock”). This agreement is being issued to the Holder in connection with an offering of
Common Stock to be conducted through the underwriters, of which Roth Capital Partners, LLC (“Roth Capital”) is the lead underwriter, that has been registered by the Company for sale to the public pursuant to the Registration Statement on
Form S-1 (No.333-145598) (“Registration Statement”), which was declared effective on             , 2006 (“Effective Date”). The shares of Common Stock that may be
issued hereunder are sometimes referred to herein as the “Securities.” The Holder can purchase, upon exercise of the Purchase Option, in whole or in part for the Securities. If the Expiration Date is a day on which banking institutions are
authorized by law to close, then this Purchase Option may be exercised on the next succeeding day that is not such a day in accordance with the terms herein. This Purchase Option is initially exercisable at
$             per share of Common Stock; provided, however, that upon the occurrence of any of the events specified in Section 6 hereof, the rights granted by this Purchase
Option, including the exercise price and the number of shares of Common Stock to be received upon such exercise, shall be adjusted as therein specified. The term “Exercise Price” shall mean the initial exercise price or the adjusted
exercise price, depending on the context of a share of Common Stock. 








	2.	Exercise. 

 2.1 Exercise Form. In order to
exercise this Purchase Option, the exercise form attached hereto must be duly executed and completed and delivered to the Company, together with this Purchase Option and payment of the Exercise Price in cash or by certified check or official bank
check for the Securities being purchased. If the subscription rights represented hereby shall not be exercised at or before 5:00 p.m., Eastern time, on the Expiration Date, this Purchase Option shall become and be void without further force or
effect, and all rights represented hereby shall cease and expire. 
 2.2 Legend. Each certificate for Securities purchased under this
Purchase Option shall bear a legend as follows (or a substantially similar legend) unless such Securities have been registered under the Securities Act of 1933, as amended: 
 “The securities represented by this certificate have not been registered under the Securities Act of 1933, as amended (“Act”) or applicable
state law. The securities may not be offered for sale, sold or otherwise transferred except pursuant to an effective registration statement under the Act, or pursuant to an exemption from registration under the Act and applicable state law.”

 2.3 Conversion Right. 
 2.3.1 Determination of Amount. In lieu of the payment of the Exercise Price in the manner required by Section 2.1, the Holder shall have the right (but not the obligation) to convert any exercisable but unexercised portion of
this Purchase Option into Common Stock (“Conversion Right”) as provided in this Section 2 below. 
 2.3.2 Common Stock.
Upon exercise of the Conversion Right, the Company shall deliver to the Holder (without payment by the Holder of any of the Exercise Price in cash) that number of shares of Common Stock equal to the quotient obtained by dividing (x) the
“Stock Value” (as defined below), at the close of trading on the next to last trading day immediately preceding the exercise of the Conversion Right, of the portion of the Purchase Option being converted by (y) the Market Price at
that same time. The “Stock Value” of the portion of the Purchase Option being converted shall equal the remainder derived from subtracting (a) the Exercise Price multiplied by the number of shares of Common Stock underlying that
portion of the Purchase Option being converted from (b) the Market Price of the Common Stock multiplied by the number of shares of Common Stock underlying that portion of the Purchase Option being converted. As used in this Section 2.3.2,
the term “Market Price” at any date shall be deemed to be the average of the last reported sale price of the Common Stock for the three consecutive trading days ending on such date, as officially reported by the principal securities
exchange on which the Common Stock is listed or admitted to trading, or, if the Common Stock is not listed 

  

 2 








 
or admitted to trading on any national securities exchange or if any such exchange on which the Common Stock is listed is not its principal trading market,
the last reported sale price for the three consecutive trading days ending on such date as furnished by the NASD through the Nasdaq National Market or SmallCap Market, or, if applicable, the American Stock Exchange, or a regional exchange, or if the
Common Stock is not listed or admitted to trading on any of the foregoing markets, or similar organization, as determined in good faith by resolution of the Board of Directors of the Company, based on the best information available to it.

 2.3.3 Mechanics of Conversion. The Conversion Right may be exercised by the Holder on any business day on or after the Commencement
Date and not later than the Expiration Date by delivering the Purchase Option with a duly executed exercise form attached hereto with the conversion right section completed to the Company, exercising the Conversion Right and specifying the total
number of shares of Common Stock that the Holder will purchase pursuant to such Conversion Right. 
  

	3.	Transfer. 

 3.1 General Restrictions. The
registered Holder of this Purchase Option, by its acceptance hereof, agrees that it will not sell, transfer, assign, pledge or hypothecate this Purchase Option prior to the Commencement Date to anyone other than (i) an officer or partner of
such Holder, (ii) an officer of either Ladenburg Thalmann & Co. Inc. or Roth Capital Partners (“Underwriter”) or an officer or partner of any Selected Dealer or member of the underwriting syndicate in connection with the
Company’s public offering with respect to which this Purchase Option has been issued, or (iii) any Selected Dealer or member of the underwriting syndicate, or engage in any hedging, short sale, derivative, put, or call transaction that
would result in the effective economic disposition of this Purchase Option or the underlying securities prior to the Commencement Date. On and after the Commencement Date, transfers to others may be made subject to compliance with or exemptions from
applicable securities laws. In order to make any permitted assignment, the Holder must deliver to the Company the assignment form attached hereto duly executed and completed, together with the Purchase Option and payment of all transfer taxes, if
any, payable in connection therewith. The Company shall immediately transfer this Purchase Option on the books of the Company and shall execute and deliver a new Purchase Option or Purchase Options of like tenor to the appropriate assignee(s)
expressly evidencing the right to purchase the aggregate number of shares of Common Stock purchasable hereunder or such portion of such number as shall be contemplated by any such assignment. 
 3.2 Restrictions Imposed by the Act. This Purchase Option and the Securities underlying this Purchase Option shall not be transferred unless and
until (i) the Company has received the opinion of counsel for the Holder that this Purchase Option or the Securities, as the case may be, may be transferred pursuant to an exemption from registration under the Act and applicable state law, the
availability of which is established to the reasonable satisfaction of the Company (the Company hereby agreeing that an opinion of Graubard Miller in form and substance reasonably satisfactory to the Company or its counsel shall be deemed
satisfactory evidence of the availability of an exemption), or (ii) a registration statement relating to such Purchase Option or Securities, as the case may be, has been filed by the Company and declared effective by the Securities and Exchange
Commission and compliance with applicable state law.

	4.	New Purchase Options to be Issued. 

 4.1 Partial
Exercise or Transfer. Subject to the restrictions in Section 3 hereof, this Purchase Option may be exercised or assigned in whole or in part. In the event of the exercise or assignment hereof in part only, upon surrender of this Purchase
Option for cancellation, together with the duly executed exercise or assignment form and funds sufficient to pay any Exercise Price and/or transfer tax, the Company shall cause to be delivered to the Holder without charge a new Purchase Option of
like tenor to this Purchase Option in the name of the Holder evidencing the right of the Holder to purchase the aggregate number of shares of Common Stock purchasable hereunder as to which this Purchase Option has not been exercised or assigned.

 4.2 Lost Certificate. Upon receipt by the Company of evidence satisfactory to it of the loss, theft, destruction or mutilation of
this Purchase Option and of reasonably satisfactory indemnification, the Company shall execute and deliver a new Purchase Option of like tenor and date. Any such new Purchase Option executed and delivered as a result of such loss, theft, mutilation
or destruction shall constitute a substitute contractual obligation on the part of the Company. 
  

	5.	Registration Rights. 

 5.1 Demand
Registration. 
 5.1.1 Grant of Right. The Company, upon written demand (“Initial Demand Notice”) of the Holder(s) of at
least 51% of the Purchase Options and/or the underlying shares of Common Stock (“Majority Holders”), agrees to register on one occasion, all of the Securities underlying such Purchase Options (collectively the “Registrable
Securities”). On such occasion, the Company will file a registration statement covering the Registrable Securities within sixty (60) days after receipt of the Initial Demand Notice and use its reasonable best efforts to have the
registration statement declared effective promptly thereafter. If the Company fails to comply with the provisions of this Section 5.1.1, the Company shall, in addition to any other equitable or other relief available to the Holder(s), be liable
for any and all incidental, special and consequential damages sustained by the Holder(s). The demand for registration may be made at any time during a period of four years beginning one year from the Effective Date; provided that the Registrable
Securities are not already covered by an effective registration statement. The Company covenants and agrees to give written notice of its receipt of any Initial Demand Notice by any Holder(s) to all other registered Holders of the Purchase Options
and/or the Registrable Securities within ten days from the date of the receipt of any such Initial Demand Notice. 
 5.1.2 Terms. The
Company shall bear all fees and expenses attendant to registering the Registrable Securities, but the Holders shall pay any and all underwriting and brokerage commissions discounts and fees, the expenses of any legal counsel selected by the Holders
to represent them in connection with the sale of the Registrable Securities. The 

  

 4 








 
Company agrees to use its reasonable best efforts to cause the filing required herein to become effective promptly and to qualify or register the Registrable
Securities in such States as are reasonably requested by the Holder(s); provided, however, that in no event shall the Company be required to register the Registrable Securities in a State in which such registration would cause (i) the Company
to be obligated to register or license to do business in such State or submit to general service of process in such State, or (ii) the principal stockholders of the Company to be obligated to escrow their shares of capital stock of the Company.
The Company shall cause any registration statement filed pursuant to the demand right granted under Section 5.1.1 to remain effective for a period of at least twelve consecutive months from the date that the Holders of the Registrable
Securities covered by such registration statement are first given the opportunity to sell all of such securities. 
 5.2
“Piggy-Back” Registration. 
 5.2.1 Grant of Right. In addition to the demand right of registration, the Holders of
the Purchase Options shall have the right for a period of five (5) years commencing one year from the Effective Date, to include the Registrable Securities as part of any other registration of securities filed by the Company (other than in
connection with a transaction contemplated by Rule 145(a) promulgated under the Act or pursuant to Form S-8 or any equivalent form); provided, however, that if, in the determination of the Company’s managing underwriter or underwriters, if any,
for such offering, the inclusion of the Registrable Securities, when added to the securities being registered by the Company or the selling stockholder(s), will exceed the maximum amount of the Company’s securities which can be marketed
(i) at a price reasonably related to their then current market value, or (ii) without adversely affecting the entire offering, the Company shall not be obligated to register such Registrable Securities. 
 5.2.2 Terms. The Company shall bear all fees and expenses attendant to registering the Registrable Securities, but the Holders shall pay any and
all underwriting and brokerage commissions, discounts and fees and the expenses of any legal counsel and other experts selected by the Holders to represent them in connection with the sale of the Registrable Securities. In the event of such a
proposed registration, the Company shall furnish the then Holders of outstanding Registrable Securities with not less than ten (10) days written notice prior to the proposed date of filing of such registration statement. Such notice to the
Holders shall continue to be given for each registration statement filed by the Company until such time as the Holder has sold all of the Registrable Securities. The holders of the Registrable Securities shall exercise the “piggy-back”
rights provided for herein by giving written notice, within ten (10) days of the receipt of the Company’s notice of its intention to file a registration statement. 
 5.3 General Terms. 
 5.3.1
Indemnification. The Company shall indemnify the Holder(s) of the Registrable Securities to be sold pursuant to any registration statement hereunder and each person, if any, who controls such Holders within the meaning of Section 15 of
the Act or Section 20(a) of the Securities Exchange Act of 1934, as amended (“Exchange Act”), against all loss, claim, damage, expense or liability (including all reasonable attorneys’ fees and other expenses 

  

 5 








 
reasonably incurred in investigating, preparing or defending against any claim whatsoever) to which any of them may become subject under the Act, the
Exchange Act or otherwise, arising from such registration statement but only to the same extent and with the same effect as the provisions pursuant to which the Company has agreed to indemnify the Underwriters contained in Section 5 of the
Underwriting Agreement between the Underwriters and the Company, dated the Effective Date (but not with respect to information furnished (or not furnished in the case of an omission) by the Holders). The Holder(s) of the Registrable Securities to be
sold pursuant to such registration statement, and their successors and assigns, shall severally, and not jointly, indemnify the Company, against all loss, claim, damage, expense or liability (including all reasonable attorneys’ fees and other
expenses reasonably incurred in investigating, preparing or defending against any claim whatsoever) to which they may become subject under the Act, the Exchange Act or otherwise, arising from information furnished (or not furnished in the case of an
omission or alleged omission) by or on behalf of such Holders, or their successors or assigns, in writing, for specific inclusion in such registration statement to the same extent and with the same effect as the provisions contained in
Section 5 of the Underwriting Agreement pursuant to which the Underwriters has agreed to indemnify the Company. 
 5.3.2 Exercise of
Purchase Option. Nothing contained in this Purchase Option shall be construed as requiring the Holder(s) to exercise their Purchase Options prior to or after the initial filing of any registration statement or the effectiveness thereof.

 5.3.3 Documents Delivered to Holders. Subject to the execution of appropriate confidentiality agreements, the Company shall deliver
promptly to each Holder participating in the offering requesting the correspondence and memoranda described below and to the managing underwriter copies of all correspondence between the Commission and the Company, its counsel or auditors and all
memoranda relating to discussions with the Commission or its staff with respect to the registration statement and permit each Holder and underwriter to do such investigation, upon reasonable advance notice, with respect to information contained in
or omitted from the registration statement as it deems reasonably necessary to comply with applicable securities laws or rules of the National Association of Securities Dealers, Inc. (“NASD”). Such investigation shall include access to
books, records and properties and opportunities to discuss the business of the Company with its officers and independent auditors, all to such reasonable extent and at such reasonable times as any such Holder shall reasonably request, provided that
all such persons sign a confidentiality agreement. 
 5.3.4 Documents to be Delivered by Holder(s). Each of the Holder(s)
participating in any of the foregoing offerings shall furnish to the Company a completed and executed questionnaire provided by the Company requesting information customarily sought of selling securityholders as a condition to the inclusion of such
Holder’s Registrable Securities in any registration statement.

	6.	Adjustments. 

 6.1 Adjustments to Exercise Price
and Number of Securities. The Exercise Price and the number of shares of Common Stock underlying the Purchase Option shall be subject to adjustment from time to time as hereinafter set forth: 
 6.1.1 Stock Dividends—Recapitalization, Reclassification, Split-Ups. If after the date hereof, and subject to the provisions of
Section 6.3 below, the number of outstanding shares of Common Stock is increased by a stock dividend payable in shares of Common Stock or by a split-up, recapitalization or reclassification of shares of Common Stock or other similar event,
then, on the effective date thereof, the number of shares of Common Stock issuable on exercise of the Purchase Option shall be increased in proportion to such increase in outstanding shares. For example, if the Company declares a two-for-one stock
dividend and at the time of such dividend the Purchase Option is for the purchase of 1,000 shares of Common Stock at $             per share, upon effectiveness of the dividend, the
Purchase Option will be adjusted (disregarding for purposes of this example that adjustments shall be rounded to the nearest cent, as provided in Section 6.1.3) to allow for the purchase of 2,000 shares at
$             per share. 
 6.1.2 Aggregation of Shares. If after
the date hereof, and subject to the provisions of Section 6.3, the number of outstanding shares of Common Stock is decreased by a consolidation, combination or reclassification of shares of Common Stock or other similar event, then, upon the
effective date thereof, the number of shares of Common Stock issuable on exercise of the Purchase Option shall be decreased in proportion to such decrease in outstanding shares. 
 6.1.3 Adjustments in Exercise Price. Whenever the number of shares of Common Stock purchasable upon the exercise of this Purchase Option is
adjusted, as provided in this Section 6.1, the Exercise Price shall be adjusted (to the nearest cent) by multiplying such Exercise Price immediately prior to such adjustment by a fraction (x) the numerator of which shall be the number of
shares of Common Stock purchasable upon the exercise of this Purchase Option immediately prior to such adjustment, and (y) the denominator of which shall be the number of shares of Common Stock so purchasable immediately thereafter. 

6.1.4 Replacement of Securities upon Reorganization, etc. In case of any reclassification or reorganization of the outstanding shares of Common
Stock other than a change covered by Section 6.1.1 hereof or which solely affects the par value of such shares of Common Stock, or in the case of any merger or consolidation of the Company with or into another corporation (other than a
consolidation or merger in which the Company is the continuing corporation and which does not result in any reclassification or reorganization of the outstanding shares of Common Stock), or in the case of any sale or conveyance to another
corporation or entity of the property of the Company as an entirety or substantially as an entirety in connection with which the Company is dissolved, the Holder of this Purchase Option shall have the right thereafter (until the expiration of the
right of exercise of this Purchase Option) to receive upon the exercise hereof, for the same aggregate Exercise Price payable hereunder immediately prior to such event, the kind and amount of shares of stock or other securities or property
(including 

  

 7 








 
cash) receivable upon such reclassification, reorganization, merger or consolidation, or upon a dissolution following any such sale or other transfer, by a
Holder of the number of shares of Common Stock of the Company obtainable upon exercise of this Purchase Option immediately prior to such event; and if any reclassification also results in a change in shares of Common Stock covered by
Section 6.1.1, then such adjustment shall be made pursuant to Sections 6.1.1, 6.1.3 and this Section 6.1.4. The provisions of this Section 6.1.4 shall similarly apply to successive reclassifications, reorganizations, mergers or
consolidations, sales or other transfers. 
 6.1.5 Changes in Form of Purchase Option. This form of Purchase Option need not be
changed because of any change pursuant to this Section, and Purchase Options issued after such change may state the same Exercise Price and the same number of shares of Common Stock as are stated in the Purchase Options initially issued pursuant to
this Agreement. The acceptance by any Holder of the issuance of new Purchase Options reflecting a required or permissive change shall not be deemed to waive any rights to a prior adjustment or the computation thereof. 
 6.2 Elimination of Fractional Interests. The Company shall not be required to issue certificates representing fractions of shares of Common Stock
upon the exercise or transfer of the Purchase Option, nor shall it be required to issue scrip or pay cash in lieu of any fractional interests, it being the intent of the parties that all fractional interests shall be eliminated by rounding any
fraction up or down to the nearest whole number of shares of Common Stock or other securities, properties or rights. 
 7. Reservation and Listing.
The Company shall at all times reserve and keep available out of its authorized shares of Common Stock, solely for the purpose of issuance upon exercise of the Purchase Options, such number of shares of Common Stock or other securities, properties
or rights as shall be issuable upon the exercise thereof. The Company covenants and agrees that, upon exercise of the Purchase Options and payment of the Exercise Price therefor, all shares of Common Stock and other securities issuable upon such
exercise shall be duly and validly issued, fully paid and non-assessable and not subject to preemptive rights of any stockholder. As long as the Purchase Options shall be outstanding, the Company shall use its reasonable best efforts to cause all
shares of Common Stock issuable upon exercise of the Purchase Options to be listed (subject to official notice of issuance) on all securities exchanges (or, if applicable on Nasdaq) on which the Common Stock are then listed and/or quoted.

  

	8.	Certain Notice Requirements. 

 8.1 Holder’s
Right to Receive Notice. Nothing herein shall be construed as conferring upon the Holders the right to vote or consent or to receive notice as a stockholder for the election of directors or any other matter, or as having any rights whatsoever as
a stockholder of the Company. If, however, at any time prior to the expiration of the Purchase Options and their exercise, any of the events described in Section 8.2 shall occur, then, in one or more of said events, the Company shall give
written notice of such event at least ten (10) days prior to the date fixed as a record date or the date of closing the transfer books for the determination of the stockholders entitled to such dividend, distribution, conversion or exchange of
securities or subscription rights, or entitled to vote on such proposed dissolution, liquidation, winding up or sale. Such notice shall specify such record date or the date of the closing of the transfer books, as the case may be. 
  

 8 








 8.2 Events Requiring Notice. The Company shall be required to give the notice described in this
Section 8 upon one or more of the following events: (i) if the Company shall take a record of the holders of its shares of Common Stock for the purpose of entitling them to receive a dividend or distribution payable otherwise than in cash,
or a cash dividend or distribution payable otherwise than out of retained earnings, as indicated by the accounting treatment of such dividend or distribution on the books of the Company, or (ii) the Company shall offer to all the holders of its
Common Stock any additional shares of capital stock of the Company or securities convertible into or exchangeable for shares of capital stock of the Company, or any option, right or warrant to subscribe therefor, or (iii) a dissolution,
liquidation or winding up of the Company (other than in connection with a consolidation or merger) or a sale of all or substantially all of its property, assets and business shall be proposed. 
 8.3 Notice of Change in Exercise Price. The Company shall, promptly after an event requiring a change in the Exercise Price pursuant to
Section 6 hereof, send notice to the Holders of such event and change (“Price Notice”). The Price Notice shall describe the event causing the change and the method of calculating same and shall be certified as being true and accurate
by the Company’s President and Chief Financial Officer. 
 8.4 Transmittal of Notices. All notices, requests, consents and other
communications under this Purchase Option shall be in writing and shall be deemed to have been duly made on the date of delivery if delivered personally or sent by overnight courier, with acknowledgement of receipt to the party to which notice is
given, or on the fifth day after mailing if mailed to the party to whom notice is to be given, by registered or certified mail, return receipt requested, postage prepaid and properly addressed as follows: (i) if to the registered Holder of the
Purchase Option, to the address of such Holder as shown on the books of the Company, or (ii) if to the Company, to its principal executive office. 
  

	9.	Miscellaneous. 

 9.1 Amendments. The Company
and Roth Capital may from time to time supplement or amend this Purchase Option without the approval of any of the Holders in order to cure any ambiguity, to correct or supplement any provision contained herein which may be defective or inconsistent
with any other provisions herein, or to make any other provisions in regard to matters or questions arising hereunder which the Company and Roth Capital may deem necessary or desirable and which the Company and Roth Capital deem shall not adversely
affect the interest of the Holders. All other modifications or amendments shall require the written consent of the party against whom enforcement of the modification or amendment is sought. 
 9.2 Headings. The headings contained herein are for the sole purpose of convenience of reference, and shall not in any way limit or affect the
meaning or interpretation of any of the terms or provisions of this Purchase Option. 
  

 9 








 9.3 Entire Agreement. This Purchase Option (together with the other agreements and documents being
delivered pursuant to or in connection with this Purchase Option) constitutes the entire agreement of the parties hereto with respect to the subject matter hereof, and supersedes all prior agreements and understandings of the parties, oral and
written, with respect to the subject matter hereof. 
 9.4 Binding Effect. This Purchase Option shall inure solely to the benefit of
and shall be binding upon, the Holder and the Company and their respective successors, legal representatives and assigns, and no other person shall have or be construed to have any legal or equitable right, remedy or claim under or in respect of or
by virtue of this Purchase Option or any provisions herein contained. 
 9.5 Governing Law; Submission to Jurisdiction. This Purchase
Option shall be governed by and construed and enforced in accordance with the laws of the State of New York, without giving effect to conflict of laws. The Company hereby agrees that any action, proceeding or claim against it arising out of, or
relating in any way to this Purchase Option shall be brought and enforced in the courts of the State of New York or of the United States of America for the Southern District of New York, and irrevocably submits to such jurisdiction, which
jurisdiction shall be exclusive. The Company hereby waives any objection to such exclusive jurisdiction and that such courts represent an inconvenient forum. Any process or summons to be served upon the Company may be served by transmitting a copy
thereof by registered or certified mail, return receipt requested, postage prepaid, addressed to it at the address set forth in Section 8 hereof. Such mailing shall be deemed personal service and shall be legal and binding upon the Company in
any action, proceeding or claim. The Company and the Holder, by acceptance hereof, agree that the prevailing party(ies) in any such action shall be entitled to recover from the other party(ies) all of its reasonable attorneys’ fees and expenses
relating to such action or proceeding and/or incurred in connection with the preparation therefor. 
 9.6 Waiver, Etc. The failure of
the Company or the Holder to at any time enforce any of the provisions of this Purchase Option shall not be deemed or construed to be a waiver of any such provision, nor to in any way affect the validity of this Purchase Option or any provision
hereof or the right of the Company or any Holder to thereafter enforce each and every provision of this Purchase Option. No waiver of any breach, non-compliance or non-fulfillment of any of the provisions of this Purchase Option shall be effective
unless set forth in a written instrument executed by the party or parties against whom or which enforcement of such waiver is sought; and no waiver of any such breach, non-compliance or non-fulfillment shall be construed or deemed to be a waiver of
any other or subsequent breach, non-compliance or non-fulfillment.
