MPV AND BS ASSIGMENT AND CONVEYANCE AGREEMENT 

          THIS
AGREEMENT (this “Agreement”) is dated 22 February 2010 and is entered
into by and between Blue Sphere Corporation, a corporation organised under the
laws of Nevada (together with its affiliates, “BS”), and Carbon MPV
Limited, a limited company organised under the laws of Cyprus,
“MPV”).

          Whereas,
MPV has identified exclusive rights to perform carbon credit projects listed
in Annex A hereto (the “Annex A Potential Projects”); 

          Whereas,
BS desires to acquire the exclusive rights to such Annex A Potential Projects
and MPV accepts and agrees to such acquisition; 

          Now,
therefore, in consideration of the mutual premises and covenants contained
herein, and subject to the terms and conditions hereof, and intending to be
legally bound, the parties hereto agree as follows: 

1.     
Assignment and Conveyance of the Projects

	1.1 	
      On the terms and subject to the conditions of this
      Agreement, MPV hereby assigns and conveys all of its right, title and
      interest in to and under (i) the Annex A Potential Projects and (ii)
      projects to be arranged by MPV in the future, which MPV offers to BS
      (“Subsequent Projects” and, together with the Annex A Potential
      Projects, the “Projects” each singularly a “Project”).

	 	 
	1.2 	
      In exchange for such assignment and conveyance, the
      parties agree that MPV shall receive with respect to each Project to be
      implemented hereunder the percentage of the gross proceeds indicated on
      Annex A from carbon credits to be received in respect of such
      Project for the life thereof upon terms to be agreed between the
      partiesMPV will also receive 4% of the net profit relating to any other
      sources of energy or energy-related revenues from such Projects over and
      for the life of the Projects. For the avoidance of doubt, it is agreed and
      acknowledged that MPV is not required to invest any funds of its own at
      any time (together all fees paid to MPV, the “Fee”).

	 	 
	1.3 	
      The Fee is inclusive of all applicable Taxes.
      “Taxes” are defined as - all taxes applicable to the transaction
      contemplated hereunder or resulting therefrom, including, without
      derogating from the generality of the above, income taxes, profit taxes,
      withholding taxes and any other compulsory payment applicable under any
      applicable law. In addition, BS shall have the right to deduct or withhold
      from any fee to be paid, any such taxes, charges or levies, in respect of
      which such deduction or withholding is required to be made according to
      any applicable law or jurisdiction.

	 	 
	1.4 	
      BS understands that certain projects may require advance
      payments and the nature and amount of such payments will become known only
      as the rights to perform such Projects are
obtained.

2.     
Project Performance and Carbon Credit Registration 

          BS
agrees to conduct due diligence promptly on each Project offered to it and, once
a decision is made, in BS’s sole discretion, to develop a Project, to use its
reasonable endeavours to implement such Project diligently and in good faith and
register and receive their carbon credits as soon as practical. BS also agrees
to use internationally recognised specialists, engineers and consultants in the
performance of Projects who have a record of success in implementing similar
projects.

      necessary for the establishment and operation of their legal and
      commercial relationship.

	 	 
	3.2 	
      Each party agrees to execute, on request, all other
      documents and instruments as the other Party shall reasonably request, and

      Agreement.

of MPV and BS agrees that it will keep confidential and not disclose to (and
require its representatives or any parties it works with in connection with any
transaction to keep confidential and not disclose to) any other person any
information that it receives that is designated as confidential as well as
information derived therefrom (“Confidential Information”) unless
authorised to do so by the disclosing party or required to do so by law. Each of
MPV and BS further agrees to refrain from taking any action (and to cause its
representatives or any parties it works with in connection with any transaction
to refrain from taking any action) using the Confidential Information that will
have the effect or the potential effect of circumventing or pre-empting, to any
degree, the disclosing party’s full and unfettered use of and benefit from its
Confidential Information. The recipient shall only put any of such Confidential
Information to its own use after receiving proper, explicit and prior
authorization from the disclosing party, in writing, to do so. It is hereby
agreed that (i) the identity of any financier or investor providing finance for
any transaction contemplated hereby is Confidential Information and (ii) MPV
shall not make any use whatsoever of the contacts brought by BS, including its
clients, government officials, facilitators or any parties using these
connections unless it has BS’s consent thereto. 

MPV represents and warrants that it has no outstanding
agreement or obligation that is in conflict with any of the provisions of this
Agreement or the rendering of the Services, or that would preclude it from
complying with the provisions hereof and that it will not enter into any
agreement or undertake any obligation which will create such a conflict of
interests. Furthermore, MPR hereby expressly certifies and represents that in
performing the Services to BS it is not in breach of any obligation towards any
third party. 

5.      Entry
into Force and Term 

          Subject
to the following sentence, this Agreement shall enter into force from the date
hereof and will terminate on the earlier of (i) 25 years from the date on which
this Agreement enters into force or (ii) the Kyoto Protocol, as amended or
extended, terminates or (iii) 15 April 2010 unless MPV delivers by such time to
BS at least two signed Project agreements and two signed Project memoranda of
understanding.

Notwithstanding anything else to the contrary herein, either
party may terminate this Agreement by written notice to the other party, if the
other party materially breaches this Agreement and fails to cure such breach
within fourteen (14) calendar days of receiving written notice thereof. Any and
all rights to accrued benefits (including, but not limited to, the right to
receive gross proceeds from any and all Projects so assigned in accordance with
Section 1.2 above or obligations to be performed after such time shall survive
any termination hereof.

  matter hereof and supersedes all previous agreements and understandings, written
  or oral, between the parties or their affiliates or agents with respect to the
  subject matter hereof. The headings in this Agreement are for convenience of
  reference only, and shall not alter or affect the meaning of any provision. Each
  party acknowledges that it has not relied upon any representation of the other
  party, except for any representation made by such party under the express terms
  of this Agreement, in entering into and undertaking the obligations imposed by
  this Agreement. This Agreement shall be construed, interpreted and enforced in
  accordance with the substantive laws of Israel. The parties agree that any
  action brought to resolve any controversy arising under or relating to this

  Tel Aviv, Israel and any court which may hear appeals from those courts in
  relation to any disputes arising out of or in connection with this Agreement. No
  Party shall be liable under this Agreement, for consequential, indirect,
  special, or punitive damages. 

7.     
Transfer to Affiliates 

          BS
acknowledges that MPV may open another company and that, once opened and
registered, BS agrees that all of MPV’s rights, obligations, title and interest
in, to and under this Agreement may, in MPV’s sole discretion, be transferred
and conveyed to such company (which may not further assign such rights) provided
that: (i) such company is a wholly owned subsidiary of MPV and (ii) such
assignment will be pursuant to a duly executed assignment agreement between the
parties, which executed assignment agreement shall be provided to BS upon its
execution. 

8.      Severability

          Should
any part of this Agreement be rendered or declared invalid by a court or
arbitrator of competent jurisdiction, such invalidation of such part or portion
of this Agreement will not invalidate the remaining portions thereof and they
shall remain in full force and effect. It is further agreed that if part of this
Agreement is determined to be invalid, either party may open negotiations solely
with respect to a substitute for such part within two (2) weeks after such
