2.1 below (the "Exercise Price"), up to that number of Shares (defined below), subject to adjustment as herein
provided (such total number of Shares that may be purchased hereunder being referred to herein as the "Warrant
Shares"). This Warrant is offered to the Holder pursuant to a Loan Agreement by and between the Holder and the Company,
dated __________________ (the "Loan Agreement") in which the Company agreed to issue this Warrant to the Holder.
Capitalized terms not defined herein shall have the meanings ascribed to them in the Loan Agreement.


 


1. Definitions. As

1.1. "Company"

which shall succeed to, by merger, consolidation or similar arrangement of the Company's and assume the obligations of
NanoFlex Power Corporation hereunder.


 


1.2. "Other
Securities" refers to any stock (other than the Shares) and other securities of the Company or any other person
(corporate or otherwise) that the Holder at any time shall be entitled to receive, or shall have received, on the exercise of
this Warrant, in lieu of or in addition to Shares, or which at any time shall be issuable or shall have been issued in
exchange for or in replacement of Shares.


 




    	 	1	 



     


    

 


1.3. "Shares"
means (a) the Company's Common Stock, as authorized on the date of this Warrant and (b) if the class of securities described
in (a) shall cease to be issued and outstanding, securities of the same class issued in exchange for or in respect of the
securities described in (a) pursuant to a plan of merger, consolidation, recapitalization or reorganization, the sale of
substantially all of the Company's assets or a similar transaction.


 


2. Exercise
of Warrant.


 


2.1. Exercise
Price. The Warrant may be exercised, subject to the adjustments in Section 5 hereof, at the initial exercise price of
$.50 per Share (the "Exercise Price").


 


2.2. Exercise
Period. The Warrant may be exercised (the "Exercise Period") at any time from the date of grant to and
including the fifth anniversary of the Issuance Date (the "Expiration Date").


 


2.3.
Shares. The number of shares that the Holder is entitled to purchase under this warrant shall be                      shares.


 


2.4. Exercise
in Full. Subject to the limitations stated above, this Warrant may be exercised in full at the option of the Holder by
surrender of this Warrant, with the form of subscription at the end hereof duly executed by the Holder, to the Company at its
principal office in the United States, accompanied by payment, in cash or by certified or official bank check payable to the
order of the Company, in the amount obtained by multiplying the number of Shares for which this Warrant may be exercised by
the Exercise Price.


 


2.5. Partial
Exercise. This Warrant may be exercised in part by surrender of this Warrant in the manner and at the place provided in
subsection 2.4 along with payment in the amount determined by multiplying (a) the number of Shares designated by the holder
in the subscription at the end hereof by (b) the Exercise Price. On any such partial exercise, the Company at its expense
will forthwith issue and deliver to or upon the order of the Holder a new Warrant or Warrants of like tenor, in the name of
the Holder or as the Holder (upon payment by the Holder of any applicable transfer taxes) may request, calling in the
aggregate on the face or faces thereof for the number of Shares for which such Warrant or Warrants may still be
exercised.


 


2.6. Cashless
Exercise. If at any time this Warrant is exercised following the one year anniversary of the date of issuance of this
Warrant, but before the Expiration Date and on the Trading Day immediately preceding the Holder's delivery of an Exercise
Notice in respect of such exercise, a registration statement (as defined covering the Warrant Shares that are the subject of
the Exercise Notice (the "Unavailable Warrant Shares") is not available for the resale of such Unavailable Warrant
Shares, the Holder of this Warrant may also exercise this Warrant as to any or all of such Unavailable Warrant Shares and, in
lieu of making the cash payment otherwise contemplated to be made to the Company upon such exercise in payment of the
aggregate Exercise Price, elect instead to receive upon such exercise a reduced number of shares of Common Stock (the
"Net Number") determined according to the following formula (a "Cashless Exercise"):


  


	 	Net Number = 	(A x B) - (A x
    C)
	 	 	              B


 




    	 	2	 



     


    

 


For
purposes of the foregoing formula:


 


A=
the total number of shares with respect to which this Warrant is then being exercised in a Cashless Exercise.


 


B=
the Market Price on the Trading Day immediately preceding the date of the Exercise Notice.


 


C=
the Exercise Price then in effect for the applicable Warrant Shares at the time of such exercise.


 


There
cannot be a Cashless Exercise unless "B" exceeds "C."


 


For
the purpose of this Warrant, the term "Trading Day" means (x) if the Common Stock is not listed on the NYSE Euronext
or NYSE AMEX but sale prices of the Common Stock are reported on Nasdaq Global Market, Nasdaq Global Select Market, Nasdaq Capital
Market or another automated quotation system, a day on which trading is reported on the principal automated quotation system on
which sales of the Common Stock are reported, (y) if the Common Stock is listed on the NYSE Euronext or NYSE AMEX, a day on which
there is trading on such stock exchange, or (z) if the foregoing provisions are inapplicable, a day on which quotations are reported
by National Quotation Bureau Incorporated.


 


3.
Delivery of Share Certificates on Exercise.


 


3.1.
As soon as practicable after the exercise of this Warrant in full or in part, the Company, at its expense (including the
payment by it of any applicable issue taxes) will cause to be issued in the name of and delivered to the Holder, or as the
Holder (upon payment by the Holder of any applicable transfer taxes) may direct, a certificate or certificates for the number
of fully paid and non-assessable Shares (or Other Securities) to which the Holder shall be entitled on such exercise, plus,
in lieu of any fractional share to which the Holder would otherwise be entitled, cash equal to such fraction multiplied by
the then current market value of one full share, together with any other stock or other securities and property (including
cash, where applicable) to which the Holder is entitled upon such exercise pursuant to Section 2 or otherwise.


 


4.
Covenants as to Shares.


 


4.1. Issuance
of Shares upon Exercise. All Shares that may be issued upon the exercise of the rights represented by this Warrant will,
upon issuance, be validly issued, fully paid and non-assessable and free from all taxes, liens and charges with respect to
the issue thereof. The Company will at all times have authorized and reserved, free from preemptive rights, a sufficient
number of its Shares to provide for the exercise of the rights represented by this Warrant.


 


4.2 Restrictions
on Transfer. Holder represents to the company that it is acquiring the Warrants for its own investment account and
without a view to the subsequent public distribution of the Warrants or Shares otherwise than pursuant to an effective
registration statement under the Securities Act.


 




    	 	3	 



     


    

 


Each
Warrant and each certificate for Shares issued to the Holder and any subsequent holder that have not been sold to the public pursuant
to an effective registration statement under the Securities Act or as to which the restrictions on transfer have not been removed
as hereinafter provided, shall bear a restrictive legend reciting that the same have not been registered pursuant to the Securities
Act and may not be transferred in the absence of an effective registration statement under the Securities Act, the holder thereof
shall give written notice to the Company of its intention to effect such transfer. Each such notice shall describe the manner
of the proposed transfer and shall be accompanied by an opinion of counsel experienced in federal securities laws matters and
reasonably acceptable to the company and its counsel to the effect that the proposed transfer may be effected without registration
under the Securities Act, whereupon, the holder of such Registrable Common Stock shall be entitled to transfer such securities
in accordance with the terms of its notice and such opinion. Restrictions imposed under this Section 4 upon the transferability
of the Warrants or of Shares shall cease when:


 


(a) a
registration statement covering such Shares becomes effective under the Securities Act, or


 


(b) the
Company receives from the holder thereof an opinion of counsel experienced in federal securities laws matters, which counsel shall
be reasonably acceptable to the Company, that such restrictions are no longer required in order to insure compliance with the
Securities Act.


 


5. Adjustment
of Exercise Price and Number of Warrant Shares.


 


5.1. Reorganization,
Consolidation or Merger. If at any time or from time to time, the Company shall (a) effect a plan of merger,
consolidation, recapitalization or reorganization or similar transaction with a corporation (the "Acquiror")
whereby the shareholders of the Company will exchange their shares of the Company for the shares of the parent corporation of
the Acquiror, or (b) transfer all or substantially all of its properties or assets to any other person, under any plan or
arrangement contemplating the dissolution of the Company (which along with any transactions set forth in (a) hereof shall be
an "Extraordinary Transaction"), then, in each such case, the holder of this Warrant, on the exercise hereof as
provided in Section 2 at any time after the completion of any Extraordinary Transaction shall receive, such Shares or Other
Securities and property (including cash) to which such holder would have been entitled in any Extraordinary Transaction as if
such holder had so exercised this Warrant, immediately prior thereto, if the holder exercises the Warrant as set forth
above.


 


Upon
any Extraordinary Transaction, this Warrant shall continue in full force and effect and the terms hereof shall be applicable to
the securities, Shares and Other Securities and property receivable on the exercise of this Warrant after the consummation of
reorganization, consolidation or merger or the effective date of dissolution following any such transfer, as the case may be,
any Extraordinary Transaction and shall be binding upon the party or parties to the Extraordinary Transaction and their successors,
including, in the case of any such transfer, the person acquiring all or substantially all of the properties or assets of the
Company, whether or not such person shall have expressly assumed the terms of this Warrant as provided in Section 7.


 


5.2. Subdivisions,
Combinations, Stock Dividends and other Issuances. If the Company shall, at any time while this Warrant is
outstanding, (i) pay a stock dividend or otherwise make a distribution or distributions on any equity securities (including
instruments or securities convertible into or exchangeable for such equity securities) in shares of Common Stock, (ii)
subdivide outstanding shares of Common Stock into a larger number of shares, or (iii) combine outstanding Common Stock into a
smaller number of shares, then the Exercise Price shall be multiplied by a fraction, the numerator of which shall be the
number of shares of Common Stock outstanding before such event and the denominator of which shall be the number of shares of
Common Stock outstanding after such event. Any adjustment made pursuant to this Section 5 shall become effective immediately
after the record date for the determination of stockholders entitled to receive such dividend or distribution and shall
become effective immediately after the effective date in the case of a subdivision or combination.


 






    	 	4	 



     


    

 


5.3. Other
Distributions. If at any time after the date hereof the Company distributes to holders of its Common Stock, other than as
part of its dissolution, liquidation or the winding up of its affairs, any shares of its capital stock, any evidence
of indebtedness or any of its assets (other than Common Stock), then the number of Warrant Shares for which this Warrant is
exercisable shall be increased to equal: (i) the number of Warrant Shares for which this Warrant is exercisable immediately
prior to such event, (ii) multiplied by a fraction, (A) the numerator of which shall be the Fair Market Value (as defined
below) per share of Common Stock on the record date for the dividend or distribution, and (B) the denominator of which shall
be the Fair Market Value price per share of Common Stock on the record date for the dividend or distribution minus the amount
allocable to one share of Common Stock of the value (as jointly determined in good faith by the Board of Directors of the
Company and the Holder) of any and all such evidences of indebtedness, shares of capital stock, other securities or property,
so distributed. For purposes of this Warrant, "Fair Market Value" shall equal the average closing trading price of
the Common Stock on the Principal Market for the five (5) Trading Days preceding the date of determination or, if the Common
Stock is not listed or admitted to trading on any Principal Market, and the average price cannot be determined as
contemplated above, the Fair Market Value of the Common Stock shall be as reasonably determined in good faith by the
Company's Board of Directors and the Holder. If the Fair Market Value of the Common Stock cannot be determined by the
Company's Board of Directors and the Holder after five (5) business days, such determination shall be made by a third party
appraisal firm mutually agreeable by the Board of Directors and the Holder, at the expense of the Company (the
"Independent Appraiser"). The fair market value as determined by the Independent Appraiser shall be final. The
Exercise Price shall be reduced to equal: (i) the Exercise Price in effect immediately before the occurrence of any event
(ii) multiplied by a fraction, (A) the numerator of which is the number of Warrant Shares for which this Warrant is
exercisable immediately before the adjustment, and (B) the denominator of which is the number of Warrant Shares for which
this Warrant is exercisable immediately after the adjustment.


 


5.4 Reclassification,
etc. If at any time after the date hereof there shall be a reorganization or reclassification of the securities as to
which purchase rights under this Warrant exist into the same or a different number of securities of any other class or
classes, then the Holder shall thereafter be entitled to receive upon exercise of this Warrant, during the period specified
herein and upon payment of the Exercise Price then in effect, the number of shares or other securities or property resulting
from such reorganization or reclassification, which would have been received by the Holder for the shares of stock subject to
this Warrant had this Warrant at such time been exercised.


 


6.
Voluntary Adjustment by the Company. The Company may at its option, at any time during the term of this Warrant, reduce
but not increase the then current Exercise Price to any amount and for any period of time deemed appropriate by the Board of Directors
of the Company.


 


7.
Notices of Record Date, etc.


 


In
the event of:


 


7.1.
any taking by the Company 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, or any right to subscribe for, purchase or otherwise acquire any
shares of stock of any class or any other securities or property, or to receive any other right, or


 






    	 	5	 



     


    

 


7.2. any
merger, consolidation or capital reorganization of the Company, any reclassification or recapitalization of the capital stock
of the Company any other person, or


 


7.3. any
voluntary or involuntary dissolution, liquidation or winding-up of the Company, then and in each such event the Company will
mail or cause to be mailed to the Holder a notice specifying (a) the date on which any such record is to be taken for the
purpose of such dividend, distribution or right, and stating the amount and character of such dividend, distribution or
right, and (b) the date on which any such reorganization, reclassification, recapitalization, transfer, consolidation,
merger, dissolution, liquidation or winding-up is to take place, and the time, if any is to be fixed, as of which the holders
of record of Shares (or Other Securities) shall be entitled to exchange their Shares (or Other Securities) for securities or
other property deliverable on such reorganization, reclassification, recapitalization, transfer, consolidation, merger,
dissolution, liquidation or winding-up. Such notice shall be mailed at least 10 days prior to the date specified in such
notice on which any such action is to be taken.


 


8.
Transfers.


 


8.1. The Warrant and the Warrant Shares are not
transferable, in whole or in part, without
compliance with the Securities Act of 1933, as amended (the "Securities Act"), and any applicable state securities
laws.


 


8.2. Subject
to subsection 8.1, this Warrant, or any portion hereof, may be transferred by the Holder's execution and delivery of the form
of assignment attached hereto along with this Warrant. Any transferee shall be required, as a condition to the assignment, to
deliver all such documentation as the Company deems appropriate. However, until such assignment and such other documentation
are presented to the Company at its principal offices in the United States, the Company shall be entitled to treat the
registered holder hereof as the absolute owner hereof for all purposes.


 


8.3. Upon
a transfer of this Warrant in accordance with this Section 8, the Company, at its expense, will issue and deliver to or on
the order of the Holder a new Warrant or Warrants of like tenor, in the name of the Holder or as the Holder (on payment by
the Holder of any applicable transfer taxes) may direct, calling in the aggregate on the face or faces thereof for the Shares
called for on the face or faces of the Warrant or Warrants so surrendered. If this Warrant is divided into more than one
Warrant, or if there is more than one Holder thereof, all references herein to "this Warrant" shall be deemed to
apply to the several Warrants, and all references to "the Holder" shall be deemed to apply to the several Holders,
except in either case to the extent that the context indicates otherwise.


 


9.
Replacement of Warrants.


 


9.1. On
receipt of evidence reasonably satisfactory to the Company of the loss, theft, destruction or mutilation of any Warrant and,
in the case of any such loss, theft or destruction of any Warrant, on delivery of an indemnity agreement or security
reasonably satisfactory in form and amount to the Company or, in the case of any such mutilation, on surrender and
cancellation of such Warrant, the Company at its expense will execute and deliver, in lieu thereof, a new Warrant of like
tenor.
