    a.           Holder
hereby agrees that during the Restriction Period, the Holder will not sell,
transfer or otherwise dispose of any shares of Common Stock or any options,
warrants or other rights to purchase shares of Common Stock or any other
security of the Company which Holder owns or has a right to acquire as of

of the Company in connection with merger, consolidation or similar transaction
involving the Company.  Holder further agrees that the Company is

Company held by Holder in violation of this Agreement.  The Company
agrees not to allow to occur any transaction inconsistent with this
Agreement.

    

    b.           Any

    b.           This
Agreement shall be governed by and construed in accordance with the laws of the
State of New York without regard to principles of conflicts of laws.  Any
action brought by either party against the other concerning the transactions
contemplated by this Agreement shall be brought only in the state courts of New
York or in the federal courts located in the state of New York.  The
parties to this Agreement hereby irrevocably waive any objection to jurisdiction
and venue of any action instituted hereunder and shall not assert any defense
based on lack of jurisdiction or venue or based upon forum non
conveniens.  The
parties executing this Agreement and other agreements referred to herein or
delivered in connection
herewith agree to submit to the in personam jurisdiction of such courts and
hereby irrevocably waive trial by jury.  The prevailing party shall
be entitled to recover from the other party its reasonable attorney's fees and
costs.  In the event that any provision of this Agreement or any other
agreement delivered in connection herewith is invalid or unenforceable under any
applicable statute or rule of law, then such provision shall be deemed
inoperative to the extent that it may conflict therewith and shall be
deemed modified to conform with such statute or rule of law.  Any such
provision which may prove invalid or unenforceable under any law shall not
affect the validity or enforceability of any other provision of any
agreement.  Notices hereunder shall be given in the same manner as set
forth in the Subscription Agreement.  Each party hereby irrevocably waives
personal service of process and consents to process being served in any suit,
action or proceeding in connection with this Agreement or any other Transaction
Document by mailing a copy thereof via registered or certified mail or overnight
delivery (with evidence of delivery) to such party at the address in effect for
notices to it under this Agreement and agrees that such service shall constitute
good and sufficient service of process and notice thereof.  Nothing
contained herein shall be deemed to limit in any way any right to serve process
in any other manner permitted by law.  Holder irrevocably appoints the
Company its true and lawful agent for service of process upon whom all processes
of law and notices may be served and given in the manner described above; and
such service and notice shall be deemed valid personal service and notice upon
Holder with the same force and validity as if served upon Holder.

    

    c.           The
restrictions on transfer described in this Agreement are in addition to and
cumulative with any other restrictions on transfer otherwise agreed to by the
Holder or to which the Holder is subject to by applicable law.

Agreement shall be binding upon Holder, its legal representatives, successors
and assigns.

Agreement may be signed and delivered by facsimile, electronically and such
facsimile or electronically signed and delivered Agreement shall be
enforceable.

    

    f.           The
Company agrees not to take any action or allow any act to be taken which would
be inconsistent with this Agreement.

    

    g.           The
Holder acknowledges that this Lockup Agreement is being entered into for the
benefit of the Subscribers identified in the Subscription Agreement may be
enforced by the Subscribers and may not be amended without the consent of the
Subscribers (in the manner described in the Subscription Agreement), which may
be withheld for any reason.

Delaware corporation (the “Company”), the signatories
hereto who are subscribers (“Prior Subscribers”) under
certain Subscription Agreements and additional transaction agreements with the
Company dated January 22, 2010 and March 4, 2010 (“Subscription Agreements”) and as
amended pursuant to the Joinder Agreement dated March 4, 2010 and the
subscribers to the Third Closing (as defined below) (each a “Third Closing Subscriber” and
collectively the “Third Closing
Subscribers”) (collectively Prior Subscribers and Third Closing
Subscribers are “Subscribers”).

    

    WHEREAS, on January 25, 2010
(the “First Closing”)
and March 4, 2010 (the “Second
Closing”), the Company consummated private placements of its
convertible notes and warrants with Subscribers pursuant to Transaction

Agreement for total consideration of $825,000.  

    

    WHEREAS, the Company is
contemplating raising an additional $250,000 (the “Purchase Price”) by issuing
its convertible notes and warrants in a third closing (“Third Closing”) to the Third
Closing Subscribers, with terms similar to the notes and warrants issued in the
First Closing and Second Closing.

    

    WHEREAS, each of the Third

foregoing closings.

    

    For good

undersigned consent to the Third Closing and to the amendment of all Schedules,

Third Closing Subscribers in connection therewith (the “Third Closing Date”), upon
satisfaction of all conditions to Closing set forth in the Transaction Documents
and in this Agreement.  The amount of the Purchase Price and all
documents to be delivered hereunder will be deposited and held with the Escrow

    6.           All
the representations, warranties and undertakings made by the Subscribers
contained in the Transaction Documents as of the First Closing and Second
Closing dates are hereby made by the Third Closing Subscribers as of the Third

made and given on the Third Closing Date.

    

    7.           The
Third Closing Subscribers will execute a Subscription Agreement, this Agreement
and the Escrow Agreement, and deliver the signatures to the Escrow Agent to be

    16.         The

    18.         Subject
to the modifications and amendments provided herein, the Transaction
Documents shall remain in full force and effect, including but not limited to
the accrual of interest and liquidated damages, if any.  Except as
expressly set forth herein, this Agreement shall not be deemed to be a
waiver, amendment or modification of any provisions of the Transaction
Documents or of any right, power or remedy of the Subscribers, or
constitute a waiver of any provision of the Transaction Documents (except
to the extent herein set forth), or any other document, instrument and/or
agreement executed or delivered in connection therewith, in each case whether
arising before or after the date hereof or as a result of performance hereunder
or thereunder.  Except as set forth herein, the Subscribers
reserve all rights, remedies, powers, or privileges available under
the Transaction Documents, at law or
otherwise.  This Agreement shall not constitute a novation or
satisfaction and accord of the Transaction Documents or any other document,
instrument and/or agreement executed or delivered in connection
therewith.

    
      
         

      

      
         

        
          

        

      

      
         

      

    

    

    19.         The
obligations of each Subscriber hereunder are several and not joint with the
obligations of any other Subscribers hereunder, and no Subscriber shall be
responsible in any way for the performance of the obligations of any other
Subscriber hereunder.  Nothing contained herein or in any other
agreement or document delivered at any closing, and no action taken by any
Subscriber pursuant hereto, shall be deemed to constitute the Subscribers as a
partnership, an association, a joint venture or any other kind of entity, or
create a presumption that the Subscribers are in any way acting in concert with
respect to such obligations or the transactions contemplated by this
Agreement.  Each Subscriber shall be entitled to protect and enforce
its rights, including without limitation the rights arising out of this
Agreement, and it shall not be necessary for any other Subscriber to be joined
as an additional party in any proceeding for such purpose, except as otherwise
agreed by the Subscribers.

    

    20.         This
Agreement shall inure to the benefit of and be binding upon the successors and
permitted assigns of each of the parties; provided, however, that no
party may assign this Agreement or the obligations and rights of such party
hereunder without the prior written consent of the other parties hereto, except
as same is permitted under the Transaction Documents.

    

    21.         This
Agreement constitutes the entire agreement among the parties regarding the
subject matter herein, and supersedes all prior and contemporaneous agreements
and understandings of the parties in connection herewith.  No changes,
modifications, terminations or waivers of any of the provisions hereof shall be
binding unless in writing and signed by all of the parties
thereto.

    

    22.         All
questions concerning the construction, validity, enforcement and interpretation
of this Agreement shall be determined pursuant to the governing law provisions
of the Transaction Documents.

    

    23.         The
language used in this Agreement will be deemed to be the language chosen by the
parties to express their mutual intent, and no rules of strict construction will
be applied against any party.

    

    24.           Each
of the undersigned states that he has read the foregoing Agreement and
understands and agrees to it.

    

    25.           This
Agreement may be executed in two or more counterparts, all of which when taken
together shall be considered one and the same agreement and shall become
effective when counterparts have been signed by each party and delivered to any
other party, it being understood that all parties need not sign the same
counterpart.  In the event that any signature is delivered by
facsimile transmission or electronically, such signature shall create a valid
and binding obligation of the party executing (or on whose behalf such signature
is executed) with the same with the same force and effect as if such facsimile
signature were an original thereof.
