($____________________) with interest on the aforesaid amount as set forth herein, which Debenture shall be payable as follows:

 

1.       Interest.

 

(A)       Interest

(B)       The
Company may prepay any portion of the principal amount of this Debenture at any time, from time to time, in whole or in part,

any financing statement filed by Payee in connection with any security interest granted under this Debenture if Payee reasonably

shall at all times have a perfected security interest in the Microreactor that shall be prior to any other interests therein.
Company shall do all acts and things, shall execute and file all instruments (including security agreements, UCC financing statements,
continuation statements, etc.) requested by Payee to establish, maintain and continue the perfected security interest of Payee
in the Microreactor, and shall promptly on demand pay all costs and expenses of (i) filing and recording, including the costs
of any searches deemed necessary by Payee from time to time to establish and determine the validity and the continuing priority
of the security interest of Payee, and (ii) all other claims and charges that in the reasonable opinion of Payee might prejudice,
imperil or otherwise affect the Microreactor or security interest therein of Payee. Company agrees that a carbon, photographic
or other reproduction of a security agreement or financing statement shall be sufficient as a financing statement. Payee is hereby
irrevocably appointed Company’s attorney-in-fact to take any of the foregoing actions requested of Company by Payee if Company
should fail to take such actions, which appointment shall be deemed coupled with an interest.

and with such deductibles as are satisfactory to Payee. All contracts and policies shall include provisions for the protection
of Payee notwithstanding any act or neglect of or breach or default by Company, shall provide for payment of insurance proceeds
to Payee, shall provide that they may not be modified, terminated or canceled unless Payee is given at least thirty (30) days’

granted, bargained, encumbered, pledged, assigned, or otherwise transferred, other than replacements consented to by Payee, without
in each instance indefeasibly paying in full in cash all sums due Payee hereunder and all other obligations having been satisfied.
A sale, conveyance, mortgage, grant, bargain, encumbrance, pledge, assignment, or transfer within the meaning of this Section
shall be deemed to include, but not limited to, (i) an installment sales agreement wherein Company agrees to sell the Microreactor
or any part thereof for a price to be paid in installments; or (ii) an agreement by Company leasing all or any part of the Microreactor.

 

(E)       The
Company, as a condition to getting paid from the escrow account, shall deliver to Payee a notarized affidavit signed by it and
FutureChemistry in the form of that attached to the escrow agreement executed contemporaneously herewith stating that amounts

4.       Conversion.

 

(A)       Prior
to the Maturity Date, the Payee may elect to convert all (but not part only) of the principal of this Debenture and any accrued
and unpaid interest into restricted shares of the Company’s Common Stock (the “Shares”), at the
conversion price of six (6) cents per share (the “Conversion Price”).

 

(i.)       If
the Payee elects to convert the principal and accrued and unpaid interest of this Debenture, the Payee shall provide written notice
to the Payor in the form attached hereto as Exhibit A (the “Conversion Notice”). If the
Payee does not provide written notice of its intention to convert the unpaid principal and any accrued and unpaid interest due,
Payor shall pay the amount due on the Maturity Date as required hereby.

 

    	 	A-3	 

    	 		 

    

 

(ii.)       If
this Debenture is converted pursuant to Paragraph (A) of this Article 4 of this Debenture, the Company shall cause its transfer
agent to deliver the Shares to the Payee within five (5) business days after the date upon which the Payor receives a Conversion
Notice (such fifth (5th) business day, the “Conversion Share Due Date”); provided, however, that a Conversion
Notice delivered after 11:00 o’clock a.m. on any business day shall be deemed to be delivered on the next following business
day.

 

(iii.)       To
effect conversions hereunder, the Payee shall be required to physically surrender this Debenture to the Company.

 

(iv.)       If
in the case of any Conversion Notice, the certificate or certificates representing the Shares are not delivered to or as directed
by the Payee by the date required hereby, the Payee shall be entitled to elect by written notice to the Company at any time on
or before its receipt of such certificate or certificates, to rescind such Conversion Notice, in which event the Company shall
promptly return to the Payee any original Debenture delivered to the Company, if applicable, and the Payee shall promptly return
to the Company the Common Stock certificates representing the principal amount of this Debenture unsuccessfully tendered for conversion
to the Company.

 

(B)       All
shares of Common Stock shall be validly issued, fully paid, and non-assessable. Company shall pay all expenses in connection with,
and all taxes that may be charged with respect to, Company’s issuance or delivery of such shares. The Payor shall pay any
and all stock transfer fees and the cost of any legal opinions needed. No fractions of shares or scrip representing fractions
of shares will be issued upon conversion, but the number of shares issued shall be rounded up to the nearest whole share, based
upon the total number of shares of Common Stock to be issued to the Payee. The date upon which a Conversion Notice is received
by the Payor shall be deemed to be the date upon which the Payee has delivered the Conversion Notice duly executed, to the Payor;
provided, however, that a Conversion Notice delivered after 11:00 o’clock a.m. on any business day shall be deemed to be
delivered on the next following business day. Upon receipt of the Shares for the full conversion and/or payment of this Debenture,
the Payee shall deliver this Debenture to the Payor marked “cancelled.”

 

(C)       If
the Company at any time after the date hereof subdivides (by any stock split, stock dividend, recapitalization or otherwise) its
outstanding shares of Common Stock into a greater number of shares, the Conversion Price prior to such subdivision will be proportionately
reduced and the number of Shares of Common Stock that the Holder may convert hereunder shall be proportionately increased, and
if the Company at any time combines (by reverse stock split or otherwise) its outstanding shares of Common Stock into a smaller
number of shares, the Conversion Price prior to such combination will be proportionately increased and the number of shares of
Common Stock that the Holder may convert hereunder shall be proportionately decreased.

 

(D)       Any
capital reorganization, reclassification, consolidation, merger or sale of all or substantially all of the Company’s assets
to another person which is effected in such a way that holders of Common Stock are entitled to receive (either directly or upon
subsequent liquidation) stock, securities or assets with respect to or in exchange for Common Stock is referred to herein as an
“Organic Change.” Prior to the consummation of any Organic Change, the Company will make appropriate
provisions to ensure that such Payee will thereafter have the right to acquire and receive, in lieu of or in addition to the shares
of Common Stock that immediately prior thereto are acquirable and receivable upon conversion of this Debenture, such shares of
stock, securities or assets as such holder would have received in connection with such Organic Change if such Holder had converted
this Debenture immediately prior to such Organic Change.

 

    	 	A-4	 

    	 		 

    

 

(E)       Whenever
the Conversion Price is adjusted pursuant to any provision of this Debenture, the Company shall promptly deliver to Payee a notice
setting forth the Conversion Price after such adjustment and setting forth a brief statement of the facts requiring such adjustment.

 

5.       Representations

Payee expressly agrees:

conflict with, or constitute a default (or an event that with notice or lapse of time or both would become a default) under, result
in the creation of any lien upon any of the properties or assets of the Company or any subsidiary, or give to others any rights
of termination, amendment, acceleration or cancellation (with or without notice, lapse of time or both) of, any material agreement,
credit facility, debt or other material instrument (evidencing a Company or subsidiary debt or otherwise) or other material understanding
to which the Company or any subsidiary is a party or by which any property or asset of the Company or any subsidiary is bound
or affected, or (iii) conflict with or result in a violation of any law, rule, regulation, order, judgment, injunction, decree

(c)Duly

5.Miscellaneous.

(b)This
Agreement may be executed in two or more counterparts and by facsimile signature or otherwise, and each of such counterparts shall
be deemed an original and all of such counterparts together shall constitute one and the same agreement.

 

(c)If
any provision of this Agreement is prohibited by law or otherwise determined to be invalid or unenforceable by a court of competent
jurisdiction, the provision that would otherwise be prohibited, invalid or unenforceable shall be deemed amended to apply to the
broadest extent that it would be valid and enforceable, and the invalidity or unenforceability of such provision shall not affect
the validity of the remaining provisions of this Agreement so long as this Agreement as so modified continues to express, without
material change, the original intentions of the parties as to the subject matter hereof and the prohibited nature, invalidity
or unenforceability of the provision(s) in question does not substantially impair the respective expectations or reciprocal obligations
of the parties or the practical realization of the benefits that would otherwise be conferred upon the parties. The parties will
endeavor in good faith negotiations to replace the prohibited, invalid or unenforceable provision(s) with a valid provision(s),
the effect of which comes as close as possible to that of the prohibited, invalid or unenforceable provision(s).

 

(d)This
Agreement shall be governed by and construed and enforced in accordance with the laws of the State of Texas (without giving effect
to any conflicts or choice of law provisions thereof).
