    COMMON
STOCK PURCHASE WARRANT

    


    To
Purchase 703,455 Shares of Common Stock of

     

    SRKP
20, Inc.

     

    THIS
COMMON STOCK PURCHASE WARRANT CERTIFIES that, for value received, [WARRANT
HOLDER] (the “Holder”), is
entitled, upon the terms and subject to the limitations on exercise and the
conditions hereinafter set forth, at any time on or after the date hereof (the
“Initial Exercise
Date”) and on or prior to the close of business on the earlier of (i) the
tenth anniversary of the Initial Exercise Date or (ii) five years from the date
the Company (as defined below) consummates a merger or other business
combination with an operating business or any other event pursuant to which the
Company ceases to be a “shell company,” as defined by Rule 12b-2 under the
Securities Exchange Act of 1934 and a “blank check company,” as defined by Rule
419 of the Securities Act (the “Termination Date”)
but not thereafter, to subscribe for and purchase from SRKP 20, Inc., a Delaware
corporation (the “Company”), up to
703,455 shares (the
“Warrant
Shares”) of the Company’s common stock, par value $.0001 per share (the
“Common
Stock”).  The purchase price of one share of Common Stock (the
“Exercise
Price”) under this Warrant shall be $0.0001, subject to adjustment
hereunder.  The Exercise Price and the number of Warrant Shares for
which the Warrant is exercisable shall be subject to adjustment as provided
herein.

    


    1.      Title to
Warrant.  At any time after the Repurchase Period (as defined
in Section 4 herein), prior to the Termination Date and subject to compliance
with applicable laws and Section 8 of this Warrant, this Warrant and all rights
hereunder are transferable, in whole or in part, at the office or agency of the
Company by the Holder in person or by duly authorized attorney, upon surrender
of this Warrant together with the Assignment Form annexed hereto properly
endorsed.  The transferee shall sign an investment letter in form and
substance reasonably satisfactory to the Company.


    
      
         


      

      
         


        
          

        

      

      
         


      

    

     

    2.      Authorization of
Shares.  The Company covenants that all Warrant Shares which
may be issued upon the exercise of the purchase rights represented by this
Warrant will, upon exercise of the purchase rights represented by this Warrant,
be duly authorized, validly issued, fully paid and nonassessable and free from
all taxes, liens and charges in respect of the issue thereof (other than taxes
in respect of any transfer occurring contemporaneously with such
issue).

     

    3.      Exercise
of Warrant.

     

    (a)           Except
as provided in Section 5 herein, exercise of the purchase rights represented by
this Warrant may be made at any time or times on or after the Initial Exercise
Date and on or before the Termination Date by the surrender of this Warrant and
the Notice of Exercise Form annexed hereto duly executed, at the office of the
Company (or such other office or agency of the Company as it may designate by
notice in writing to the registered Holder at the address of such Holder
appearing on the books of the Company).  Upon payment of the Exercise
Price of the shares thereby purchased by wire transfer or cashier’s check drawn
on a United States bank, the Holder shall be entitled to receive a certificate
for the number of Warrant Shares so purchased.  Certificates for
Warrant Shares purchased hereunder shall be delivered to the Holder within five
(5) business days after the date on which this Warrant shall have been exercised
as aforesaid. This Warrant shall be deemed to have been exercised and such
certificate or certificates shall be deemed to have been issued, and Holder or
any other person so designated to be named therein shall be deemed to have
become a holder of record of such Warrant Shares for all purposes, as of the
date the Warrant has been exercised by payment to the Company of the Exercise
Price and all taxes required to be paid by the Holder, if any, pursuant to
Section 6 prior to the issuance of such shares, have been paid.  If
the Company fails to deliver to the Holder a certificate or certificates
representing the Warrant Shares pursuant to this Section 3(a) by the fifth
business day after the date of exercise, then the Holder will have the right to
rescind such exercise by written notice to the Company.

     

    (b)           If
this Warrant shall have been exercised in part, the Company shall, at the time
of delivery of the certificate or certificates representing Warrant Shares,
deliver to Holder a new Warrant evidencing the rights of Holder to purchase the
unpurchased Warrant Shares called for by this Warrant, which new Warrant shall
in all other respects be identical with this Warrant.

    (c)              This
Warrant may also be exercised, in whole or in part, at any time prior to the
Termination Date, by means of a “cashless exercise” in which the Holder shall be
entitled to receive a certificate for the number of Warrant Shares equal to the
quotient obtained by dividing [(A-B) (X)] by (A), where:

     

    
      	
               
      

            	
              (A)
      = the closing bid price on the trading day preceding the date of such
      election;

            


    

    


    
      	
               
      

            	
              (B)
      = the Exercise Price of the Warrants, as adjusted;
  and

            


    

    


    
      	
                
      

            	
               
      (X) = the number of Warrant Shares issuable upon exercise of the Warrants
      in accordance
      with the terms of 

                         
      this Warrant.

            


    

    


    4.      Repurchase Option.
For a period of one year from the date of this Agreement (the “Repurchase
Period”), the Company shall have an irrevocable, exclusive option, but not the
obligation, to repurchase all or any portion of this Warrant (the "Repurchase
Option").  The Repurchase Option shall be exercisable at a price equal to
the purchase price as set forth in that certain Warrant Purchase Agreement,
dated November 3,
2010 by and between the Company and the HOLDER (the "Repurchase
Price"). The Repurchase Option shall be exercisable by the Company, at any time,
by delivering written notice (the “Repurchase Notice”) to the Purchaser of its
election to exercise its Repurchase Option. The Repurchase Notice shall provide
(i) that the Company is exercising its Repurchase Option in connection with this
Agreement; (ii) whether the Company is repurchasing all of or a portion of, the
Warrant (the Repurchased Warrant”) and (iii) the aggregate Repurchase Price to
be paid for the Repurchased Warrant.  The Repurchase Notice shall be
accompanied by a check made out in the name of the Purchaser, or other
immediately available funds, for an amount equal to the Repurchase Price. Upon
delivery of the Repurchase Notice and the Repurchase Price, the Warrant so
repurchased and all rights and interests therein or relating thereto shall be
deemed canceled and the Company shall have the right to retain and transfer to
its own name the Repurchased Warrant. The Repurchase Option set forth in this
Section may be assigned by the Company in whole or in part in its sole
discretion. If at any time during the Repurchase Period, the Company consummates
(a) a merger or other business combination with an operating business or (b) a
transaction pursuant to which the Company ceases to be a “shell company,” as
defined by Rule 12b-2 under the Securities Exchange Act of 1934, as amended and
a “blank check company” as defined by Rule 419 of the Securities Act of 1933, as
amended, the Repurchase Option shall terminate thereupon.

     

    5.      No Fractional Shares or
Scrip.  No fractional shares or scrip representing fractional
shares shall be issued upon the exercise of this Warrant.  As to any
fraction of a share which Holder would otherwise be entitled to purchase upon
such exercise, the Company shall pay a cash adjustment in respect of such final
fraction in an amount equal to such fraction multiplied by the Exercise
Price.

     

    6.      Charges, Taxes and
Expenses.  Issuance of certificates for Warrant Shares shall be
made without charge to the Holder for any issue or transfer tax or other
incidental expense in respect of the issuance of such certificate, all of which
taxes and expenses shall be paid by the Company, and such certificates shall be
issued in the name of the Holder or in such name or names as may be directed by
the Holder; provided, however, that in the event certificates for Warrant Shares
are to be issued in a name other than the name of the Holder, this Warrant when
surrendered for exercise shall be accompanied by the Assignment Form attached
hereto duly executed by the Holder; and the Company may require, as a condition
thereto, the payment of a sum sufficient to reimburse it for any transfer tax
incidental thereto.

    7.      Closing of
Books.  The Company will not close its stockholder books or
records in any manner which prevents the timely exercise of this Warrant,
pursuant to the terms hereof.

     

    8.      Transfer, Division and
Combination.

     

    (a)           Subject
to compliance with any applicable securities laws and the conditions set forth
in Sections 1 and 8(e) hereof, this Warrant and all rights hereunder are
transferable, in whole or in part, upon surrender of this Warrant at the
principal office of the Company, together with a written assignment of this
Warrant substantially in the form attached hereto duly executed by the Holder or
its agent or attorney and funds sufficient to pay any transfer taxes payable
upon the making of such transfer.  Upon such surrender and, if
required, such payment, the Company shall execute and deliver a new Warrant or
Warrants in the name of the assignee or assignees and in the denomination or
denominations specified in such instrument of assignment, and shall issue to the
assignor a new Warrant evidencing the portion of this Warrant not so assigned,
and this Warrant shall promptly be cancelled.  A Warrant, if properly
assigned, may be exercised by a new holder for the purchase of Warrant Shares
without having a new Warrant issued.

     

    (b)      
   This Warrant may be divided or combined with other Warrants
upon presentation hereof at the aforesaid office of the Company, together with a
written notice specifying the names and denominations in which new Warrants are
to be issued, signed by the Holder or its agent or attorney.  Subject
to compliance with Section 8(a), as to any transfer which may be involved in
such division or combination, the Company shall execute and deliver a new
Warrant or Warrants in exchange for the Warrant or Warrants to be divided or
combined in accordance with such notice.

     

    (c)           The
Company shall prepare, issue and deliver at its own expense (other than transfer
taxes) the new Warrant or Warrants under this Section 8.

     

    (d)           The
Company agrees to maintain, at its aforesaid office, books for the registration
and the registration of transfer of the Warrants.

     

    (e)           If,
at the time of the surrender of this Warrant in connection with any transfer of
this Warrant, the transfer of this Warrant shall not be registered pursuant to
an effective registration statement under the Securities Act and under
applicable state securities or blue sky laws, the Company may require, as a
condition of allowing such transfer, (i) that the Holder or transferee of this
Warrant, as the case may be, furnish to the Company a written opinion of counsel
reasonably acceptable to the Company (which opinion shall be in form, substance
and scope customary for opinions of counsel in comparable transactions) to the
effect that such transfer may be made without registration under the Securities
Act and under applicable state securities or blue sky laws and (ii) that the
holder or transferee execute and deliver to the Company an investment letter in
form and substance acceptable to the Company.

    9.   
No Rights as
Shareholder until Exercise.  This Warrant does not entitle the
Holder to any voting rights or other rights as a shareholder of the Company
prior to the exercise hereof.  Upon the surrender of this Warrant and
the payment of the aggregate Exercise Price, the Warrant Shares so purchased
shall be and be deemed to be issued to such Holder as the record owner of such
shares as of the close of business on the later of the date of such surrender or
payment.

     

    10. 
Loss, Theft,
Destruction or Mutilation of Warrant.  The Company covenants
that upon receipt by the Company of evidence reasonably satisfactory to it of
the loss, theft, destruction or mutilation of this Warrant or any stock
certificate relating to the Warrant Shares, and in case of loss, theft or
destruction, of indemnity or security reasonably satisfactory to it (which, in
the case of the Warrant, shall not include the posting of any bond), and upon
surrender and cancellation of such Warrant or stock certificate, if mutilated,
the Company will make and deliver a new Warrant or stock certificate of like
tenor and dated as of such cancellation, in lieu of such Warrant or stock
certificate.

     

    11.   Saturdays, Sundays,
Holidays, etc.  If the last or appointed day for the taking of
any action or the expiration of any right required or granted herein shall be a
Saturday, Sunday or a legal holiday, then such action may be taken or such right
may be exercised on the next succeeding day not a Saturday, Sunday or legal
holiday.

     

    12.   Adjustments of Exercise
Price and Number of Warrant Shares.  The number and kind of
securities purchasable upon the exercise of this Warrant and the Exercise Price
shall be subject to adjustment from time to time upon the happening of any of
the following.  In case the Company shall (i) pay a dividend in shares
of Common Stock or make a distribution in shares of Common Stock to holders of
its outstanding Common Stock, (ii) subdivide its outstanding shares of Common
Stock into a greater number of shares, (iii) combine its outstanding shares of
Common Stock into a smaller number of shares of Common Stock, or (iv) issue any
shares of its capital stock in a reclassification of the Common Stock, then in
each such case the number of Warrant Shares purchasable upon exercise of this
Warrant immediately prior thereto shall be adjusted so that the Holder shall be
entitled to receive the kind and number of Warrant Shares or other securities of
the Company which it would have owned or have been entitled to receive had such
Warrant been exercised in advance thereof.  Upon each such adjustment
of the kind and number of Warrant Shares or other securities of the Company
which are purchasable hereunder, the Holder shall thereafter be entitled to
purchase the number of Warrant Shares or other securities resulting from such
adjustment at an Exercise Price per Warrant Share or other security obtained by
multiplying the Exercise Price in effect immediately prior to such adjustment by
the number of Warrant Shares purchasable pursuant hereto immediately prior to
such adjustment and dividing by the number of Warrant Shares or other securities
of the Company resulting from such adjustment.  An adjustment made
pursuant to this paragraph shall become effective immediately after the
effective date of such event retroactive to the record date, if any, for such
event.

    13.        
   Reorganization,
Reclassification, Merger, Consolidation or Disposition of
Assets.  In case the Company shall reorganize its capital,
reclassify its capital stock, consolidate or merge with or into another
corporation (where the Company is not the surviving corporation or where there
is a change in or distribution with respect to the Common Stock of the Company),
or sell, transfer or otherwise dispose of all or substantially all its property,
assets or business to another corporation and, pursuant to the terms of such
reorganization, reclassification, merger, consolidation or disposition of
assets, shares of common stock of the successor or acquiring corporation, or any
cash, shares of stock or other securities or property of any nature whatsoever
(including warrants or other subscription or purchase rights) in addition to or
in lieu of common stock of the successor or acquiring corporation (“Other
Property”), are to be received by or distributed to the holders of Common Stock
of the Company, then the Holder shall have the right thereafter to receive, at
the option of the Holder, upon exercise of this Warrant, the number of shares of
Common Stock of the successor or acquiring corporation or of the Company, if it
is the surviving corporation, and Other Property receivable upon or as a result
of such reorganization, reclassification, merger, consolidation or disposition
of assets by a Holder of the number of shares of Common Stock for which this
Warrant is exercisable immediately prior to such event.  In case of
any such reorganization, reclassification, merger, consolidation or disposition
of assets, the successor or acquiring corporation (if other than the Company)
shall expressly assume the due and punctual observance and performance of each
and every covenant and condition of this Warrant to be performed and observed by
the Company and all the obligations and liabilities hereunder, subject to such
modifications as may be deemed appropriate (as determined in good faith by
resolution of the Board of Directors of the Company) in order to provide for
adjustments of Warrant Shares for which this Warrant is exercisable which shall
be as nearly equivalent as practicable to the adjustments provided for in this
Section 13.  For purposes of this Section 13, “common stock of the
successor or acquiring corporation” shall include stock of such corporation of
any class which is not preferred as to dividends or assets over any other class
of stock of such corporation and which is not subject to redemption and shall
also include any evidences of indebtedness, shares of stock or other securities
which are convertible into or exchangeable for any such stock, either
immediately or upon the arrival of a specified date or the happening of a
specified event and any warrants or other rights to subscribe for or purchase
any such stock.  The foregoing provisions of this Section 13 shall
similarly apply to successive reorganizations, reclassifications, mergers,
consolidations or disposition of assets.

     

    14.      
     Voluntary Adjustment by the
Company.  The Company may at any time during the term of this
Warrant reduce the then current Exercise Price to any amount and for any period
of time deemed appropriate by the Board of Directors of the
Company.

     

    15.      
     Notice of
Adjustment.  Whenever the number of Warrant Shares or number or
kind of securities or other property purchasable upon the exercise of this
Warrant or the Exercise Price is adjusted, as herein provided, the Company shall
give notice thereof to the Holder, which notice shall state the number of
Warrant Shares (and other securities or property) purchasable upon the exercise
of this Warrant and the Exercise Price of such Warrant Shares (and other
securities or property) after such adjustment, setting forth a brief statement
of the facts requiring such adjustment and setting forth the computation by
which such adjustment was made.

     

    16.       
    Notice of Corporate Action.  If at any
time:

     

    (a)           the
Company shall take a record of the holders of its Common Stock for the purpose
of entitling them to receive a dividend or other distribution, or any right to
subscribe for or purchase any evidences of its indebtedness, any shares of stock
of any class or any other securities or property, or to receive any other right,
or

     

    
      
         


      

      
        6

        
          

        

      

      
         


      

    


    (b)           there
shall be any capital reorganization of the Company, any reclassification or
recapitalization of the capital stock of the Company or any consolidation or
merger of the Company with, or any sale, transfer or other disposition of all or
substantially all the property, assets or business of the Company to, another
corporation or,

     

    (c)           there
shall be a voluntary or involuntary dissolution, liquidation or winding up of
the Company;

     

    then, in
any one or more of such cases (but not in such cases if the rights of the Holder
or holders of Common Stock will not be materially affected thereby, as for
example in the case of a merger to effect a change of domicile), the Company
shall give to Holder (i) at least 5 business days’ prior notice of the date on
which a record date shall be selected for such dividend, distribution or right
or for determining rights to vote in respect of any such reorganization,
reclassification, merger, consolidation, sale, transfer, disposition,
liquidation or winding up, and (ii) in the case of any such reorganization,
reclassification, merger, consolidation, sale, transfer, disposition,
dissolution, liquidation or winding up, at least 5 business days’ prior notice
of the date when the same shall take place.  Such notice in accordance
with the foregoing clause also shall specify (i) the date on which any such
record is to be taken for the purpose of such dividend, distribution or right,
the date on which the holders of Common Stock shall be entitled to any such
dividend, distribution or right, and the amount and character thereof, and (ii)
the date on which any such reorganization, reclassification, merger,
consolidation, sale, transfer, disposition, dissolution, liquidation or winding
up is to take place and the time, if any such time is to be fixed, as of which
the holders of Common Stock shall be entitled to exchange their Warrant Shares
for securities or other property deliverable upon such disposition, dissolution,
liquidation or winding up.  Each such written notice shall be
sufficiently given if addressed to Holder at the last address of Holder
appearing on the books of the Company and delivered in accordance with Section
18(d).

     

    17.  Authorized
Shares.  The Company covenants that during the period the
Warrant is outstanding, it will reserve from its authorized and unissued Common
Stock a sufficient number of shares to provide for the issuance of the Warrant
Shares upon the exercise of any purchase rights under this
Warrant.  The Company further covenants that its issuance of this
Warrant shall constitute full authority to its officers who are charged with the
duty of executing stock certificates to execute and issue the necessary
certificates for the Warrant Shares upon the exercise of the purchase rights
under this Warrant.  The Company will take all such reasonable action
as may be necessary to assure that such Warrant Shares may be issued as provided
herein without violation of any applicable law or regulation, or of any
requirements of the trading market upon which the Common Stock may be
listed.

    Except and to the extent as waived or
consented to by the Holder, the Company shall not by any action, including,
without limitation, amending its certificate of incorporation or through any
reorganization, transfer of assets, consolidation, merger, dissolution, issue or
sale of securities or any other voluntary action, avoid or seek to avoid the
observance or performance of any of the terms of this Warrant, but will at all
times in good faith assist in the carrying out of all such terms and in the
taking of all such actions as may be necessary or appropriate to protect the
rights of Holder as set forth in this Warrant against
impairment.  Without limiting the generality of the foregoing, the
Company will (a) not increase the par value of any Warrant Shares above the
amount payable therefor upon such exercise immediately prior to such increase in
par value, (b) take all such action as may be necessary or appropriate in order
that the Company may validly and legally issue fully paid and nonassessable
Warrant Shares upon the exercise of this Warrant, and (c) use commercially
reasonable efforts to obtain all such authorizations, exemptions or consents
from any public regulatory body having jurisdiction thereof as may be necessary
to enable the Company to perform its obligations under this
Warrant.

    


    Before taking any action which would
result in an adjustment in the number of Warrant Shares for which this Warrant
is exercisable or in the Exercise Price, the Company shall obtain all such
authorizations or exemptions thereof, or consents thereto, as may be necessary
from any public regulatory body or bodies having jurisdiction
thereof.

    


    18.          Miscellaneous.

    


    (a)           Jurisdiction.  This
Warrant shall constitute a contract under the laws of Delaware, without regard
to its conflicts of laws principles or rules.

     

    (b)           Restrictions.  The
Holder acknowledges that the Warrant Shares acquired upon the exercise of this
Warrant, if not registered, will have restrictions upon resale imposed by state
and federal securities laws.

     

    (c)           Nonwaiver and
Expenses.  No course of dealing or any delay or failure to
exercise any right hereunder on the part of Holder shall operate as a waiver of
such right or otherwise prejudice Holder’s rights, powers or remedies,
notwithstanding all rights hereunder terminate on the Termination
Date.  If the Company willfully and knowingly fails to comply with any
provision of this Warrant, which results in any material damages to the Holder,
the Company shall pay to Holder such amounts as shall be sufficient to cover any
costs and expenses including, but not limited to, reasonable attorneys’ fees,
including those of appellate proceedings, incurred by Holder in collecting any
amounts due pursuant hereto or in otherwise enforcing any of its rights, powers
or remedies hereunder.

     

    (d)           Notices.  Any
notice, request or other document required or permitted to be given or delivered
pursuant to this Warrant shall be deemed to have been sufficiently given and
received for all purposes when delivered by hand or by telecopy that has been
confirmed as received by 5:00 P.M. on a business day, one (1) business day after
being sent by nationally recognized overnight courier or received by telecopy
after 5:00 P.M. on any day, or five (5) business days after being sent by
certified or registered mail, postage and charges prepaid, return receipt
requested, to the following addresses:

Holder:    At the Holder’s address in the Company’s Warrant
register.

    


    (e)           Limitation of
Liability.  No provision hereof, in the absence of any
affirmative action by Holder to exercise this Warrant or purchase Warrant
Shares, and no enumeration herein of the rights or privileges of Holder, shall
give rise to any liability of Holder for the purchase price of any Common Stock
or as a stockholder of the Company, whether such liability is asserted by the
Company or by creditors of the Company.

     

    (f)            Remedies.  Holder,
in addition to being entitled to exercise all rights granted by law, including
recovery of damages, will be entitled to specific performance of its rights
under this Warrant.  The Company agrees that monetary damages would
not be adequate compensation for any loss incurred by reason of a breach by it
of the provisions of this Warrant and hereby agrees to waive the defense in any
action for specific performance that a remedy at law would be
adequate.

     

    (g)           Successors and
Assigns.  Subject to applicable securities laws, this Warrant
and the rights and obligations evidenced hereby shall inure to the benefit of
and be binding upon the successors of the Company and the successors and
permitted assigns of Holder.  The provisions of this Warrant are
intended to be for the benefit of all Holders from time to time of this Warrant
and shall be enforceable by any such Holder or holder of Warrant
Shares.

     

    (h)           Amendment.  This
Warrant may be modified or amended or the provisions hereof waived with the
written consent of the Holder and the Company.

     

    (i)            Severability.  Wherever
possible, each provision of this Warrant shall be interpreted in such manner as
to be effective and valid under applicable law, but if any provision of this
Warrant shall be prohibited by or invalid under applicable law, such provision
shall be ineffective to the extent of such prohibition or invalidity, without
invalidating the remainder of such provisions or the remaining provisions of
this Warrant.

     

    (j)            Headings.  The
headings used in this Warrant are for the convenience of reference only and
shall not, for any purpose, be deemed a part of this Warrant.
