      2009
|         | Albany, New
      York 

For value
received, MTI MicroFuel Cells Inc., aDelaware corporation (the Company), promises to pay
to Counter Point Ventures Fund II, LP (the Holder), the principal sum of
$500,000. Interest shall accrue from the date of this Note on the unpaid
principal amount at a rate equal to 10.0% per annum, compounded annually.This Note
is one of a series of Secured Convertible Promissory Notes containing
substantially identical terms and conditions issued pursuant to that certain
Convertible Note and Warrant Purchase Agreement dated September 18, 2008, as
amended (the Purchase
Agreement). Such Notes are referred to
herein as the Notes, and the holders thereof are referred to herein as the
Holders.This Note
is subject to the following terms and conditions.

1.Maturity.Unless converted as provided in
Section 2 below, all unpaid principal and accrued interest under this Note shall
be due and payable upon demand by the Holder at any time on or after May 31,
2009 (the Maturity Date), except as otherwise provided hereunder. Notwithstanding
the foregoing, the entire unpaid principal sum of this Note, together with
accrued and unpaid interest thereon, shall become immediately due and payable
upon the insolvency of the Company, the commission of any act of bankruptcy by
the Company, the execution by the Company of a general assignment for the
benefit of creditors, the filing by or against the Company of a petition in
bankruptcy or any petition for relief under the federal bankruptcy act or the
continuation of such petition without dismissal for a period of 90 days or more,
or the appointment of a receiver or trustee to take possession of the property
or assets of the Company.

2.Conversion.

(a)Investment by the
Holder.

(i) The entire principal amount of and (at the Companys
option)accrued but unpaid interest on this Note will automatically convert into
shares of the Companys preferred stock (the Next Equity Preferred) issued and
sold in the Companys next equity financing in a single or a series of related
transactions yielding gross proceeds to the Company of at least $3,500,000
(including conversion, in whole or in part, of any Notes) (the Next EquityFinancing). The number of shares of
Next Equity Preferred to be issued upon such conversion shall be equal to the
quotient obtained by dividing (a) the entire principal amount of this Note plus
(if applicable) accrued but unpaid interest, by (b) the price per share of the
Next Equity Preferred, rounded down to the nearest whole share, and the issuance
of such shares upon such conversion shall be upon the terms and subject to the
conditions applicable to the Next Equity Financing.

-5-

---

(ii) If the Next Equity Financing does not occur on or before
the Maturity Date, all principal and (at
the Companys option) accrued interest
outstanding under all of the Notes shall be converted into equity securities of
the Company (Equity Securities) based upon a Company valuation and on
such terms to be agreed upon by the Company and the holders of a majority in interest of the Notes within
thirty (30) days following the Maturity Date, which valuation and terms shall be
negotiated in good faith by the Company and a majority in interest of the Notes
(a Negotiated Conversion). If the Company and holders of a majority in
interest of the Notes cannot agree upon the valuation and terms of a Negotiated
Conversion, and fail to consummate such Negotiated Conversion within thirty (30)
days following the Maturity Date, then all principal and accrued interest
outstanding under the Notes shall be due and payable upon demand by the Holders
at any time thereafter.

(iii) Notwithstanding the above, in the event a Change of
Control (as defined below) is consummated prior to the Next Equity Financing, a
Negotiated Conversion, or the repayment in full of all principal and accrued
interest under the Notes, then the Notes shall become immediately due and
payable in an amount equal to 125% of the principal amount of the Note(s) and
100% of the accrued interest outstanding thereon, payment of which shall be in
full satisfaction of the Note(s) and shall be made within thirty (30) days
following the consummation of such Change of Control.

(iv)The term Change of
Control shall mean the sale, conveyance or
other disposition of all or substantially all of the Companys property or
business or the Companys merger with or into or consolidation with any other
corporation, limited liability company or other entity (other than a wholly
owned subsidiary of the Company), provided that the term Change of Control
shall not include a merger of the Company effected exclusively for the purpose
of changing the domicile of the Company, to an equity financing in which the
Company is the surviving corporation, or to a transaction in which the
stockholders of the Company immediately prior to the transaction own 50% or more
of the voting power of the surviving corporation following the
transaction.

(b)Mechanics and Effect
of Conversion.Upon conversion of this Note pursuant to this Section 2, the
Holder shall surrender this Note, duly endorsed, at the principal offices of the
Company or any transfer agent of the Company. At its expense, the Company will,
as soon as practicable thereafter, issue and deliver to such Holder, at such
principal office, a certificate or certificates for the number of shares to
which such Holder is entitled upon such conversion, together with any other
securities and property to which the Holder is entitled upon such conversion
under the terms of this Note, including a check payable to the Holder for any
cash amounts payable as described herein. Upon conversion of this Note, the
Company will be forever released from all of its obligations and liabilities
under this Note with regard to that portion of the principal amount and accrued
interest being converted including without limitation the obligation to pay such
portion of the principal amount and accrued interest.

(c)Payment of
Interest.Upon conversion of the principal amount of this Note into the Companys
Next Equity Preferred or Equity Securities, as applicable, any interest accrued
on this Note that is not by reason of Section 2(a) hereof simultaneously
converted into Next Equity Preferred or Equity Securities, as applicable, shall
be immediately paid to the Holder.

3.Payment; Prepayment.All payments shall be made in lawful
money of theUnited States of America at such
place as the Holder hereof may from time to time designate in writing to the
Company. Payment shall be credited first to the accrued interest then due and
payable and the remainder applied to principal. Prepayment of this Note may be
made at any time without penalty.

Assigns.The terms and conditions of this Note shall inure to the benefit of and
be binding upon the respective successors and assigns of the parties.

transfer this Note without the prior written consent of the Company. Subject to
the preceding sentence, this Note may be transferred only upon surrender of the
original Note for registration of transfer, duly endorsed, or accompanied by a
duly executed written instrument of transfer in form satisfactory to the
Company. Thereupon, a new note for the appropriate principal amount and interest
will be issued to, and registered in the name of, the transferee. Interest and
principal are payable only to the registered holder of this Note.

and transactions pursuant hereto and the rights and obligations of the parties
hereto shall be governed, construed and interpreted in accordance with the laws
of the State of Delaware, without giving effect to principles of conflicts of
law.

Agreement) of even date herewith between the

| | --------- | ---------
| |           | A        

|Where: | X = | The number of
      shares of Warrant Stock to be issued to the Holder.                                            
|------ | --- | -------------------------------------------------------------------------------------------------------------------
|       |     |                                                                                                                    
|       | Y = | The number of
      shares of Warrant Stock purchasable under this Warrant (at the date of
      such calculation).
|       |     |                                                                                                                    
|       | A = | The fair market
      value of one share of Warrant Stock (at the date of such
      calculation).                 
|       |     |                                                                                                                    
|       | B = | The Purchase
      Price (as adjusted to the date of such calculation).                                            

(ii) For purposes of this Section 2(c), the fair market value
of Warrant Stock on the date of calculation shall mean with respect to each
share of Warrant Stock:

(A) if the exercise is in connection with an initial public
offering of the Companys Common Stock, and if the Companys Registration
Statement relating to such public offering has been declared effective by the
Securities and Exchange Commission, then the fair market value shall be the
product of (x) the initial Price to Public per share specified in the final
prospectus with respect to the offering and (y) the number of shares of Common
Stock into which each share of Warrant Stock is convertible at the date of
calculation;

-11-

---

(B)if (A) is not applicable, the fair market value of Warrant
Stock shall be at the highest price per share which the Company could obtain on
the date of calculation from a willing buyer (not a current employee or
director) for shares of Warrant Stock sold by the Company, from authorized but
unissued shares, as determined in good faith by the Board of Directors, unless
the Company is at such time subject to an acquisition as described in Section 6
below, in which case the fair market value of Warrant Stock shall be deemed to
be the value received by the holders of such stock pursuant to such acquisition.

(d)Delivery to
Holder.As soon as practicable after the exercise of this Warrant in whole or in
part, and in any event within ten (10) days thereafter, the Company at its
expense will cause to be issued in the name of, and delivered to, the Holder, or
as such Holder (upon payment by such Holder of any applicable transfer taxes)
may direct:

(i) a certificate or certificates for the number of shares of
Warrant Stock to which such Holder shall be entitled; and

(ii) in case such exercise is in part only, a new warrant or
warrants (dated the date hereof) of like tenor, calling in the aggregate on the
face or faces thereof for the number of shares of Warrant Stock equal (without
giving effect to any adjustment therein) to the number of such shares called for
on the face of this Warrant minus the number of such shares purchased by the
Holder upon such exercise as provided in Section 2(a) or 2(c) above.

3.Adjustments.

(a)Stock Splits and
Dividends.If outstanding shares of the Companys Common Stock shall be subdivided
into a greater number of shares or a dividend in Common Stock shall be paid in
respect of Common Stock, the Purchase Price in effect immediately prior to such
subdivision or at the record date of such dividend shall simultaneously with the
effectiveness of such subdivision or immediately after the record date of such
dividend be proportionately reduced. If outstanding shares of Common Stock shall
be combined into a smaller number of shares, the Purchase Price in effect
immediately prior to such combination shall, simultaneously with the
effectiveness of such combination, be proportionately increased. When any
adjustment is required to be made in the Purchase Price, the number of shares of
Warrant Stock purchasable upon the exercise of this Warrant shall be changed to
the number determined by dividing (i) an amount equal to the number of shares
issuable upon the exercise of this Warrant immediately prior to such adjustment,
multiplied by the Purchase Price in effect immediately prior to such adjustment;
by (ii) the Purchase Price in effect immediately after such adjustment.

(b)Reclassification,
Etc.In case there occurs any reclassification or change of the outstanding
securities of the Company or of any reorganization of the Company (or any other
corporation the stock or securities of which are at the time receivable upon the
exercise of this Warrant) or any similar corporate reorganization on or after
the date hereof,then and in each such case the Holder, upon the exercise hereof at any
time after the consummation of such reclassification, change,or reorganization shall be entitled
to receive, in lieu of the stock or other securities and property receivable
upon the exercise hereof prior to such consummation, the stock or other
securities or property to which such Holder would have been entitled upon such
consummation if such Holder had exercised this Warrant immediately prior
thereto, all subject to further adjustment pursuant to the provisions of this
Section 3; provided, however, that the operation of this Section 3(b) shall not
effect the termination of this Warrant upon a Change of Control (as defined in
Section 6 below) pursuant to Section 6 below.
