        Parties hereto in the drilling of an initial exploratory well at the location set out
        herein on the Prospect for the exploration and production of oil and gas according to the
        terms and conditions of this Agreement;

        

        
                NOW,
        THEREFORE, in consideration of the foregoing recitals and premises and of the mutual
        covenants, agreements and obligations herein contained, the Parties hereto do hereby agree
        as follows:

        

        ARTICLE I: 
        CONTRACT AREA

        

        
                The
        area subject to this Agreement shall encompass all of the area, whether owned now or
        acquired in the future by any of the Parties, located within the geographic boundaries of
        the area depicted and outlined by a heavy line on Exhibit “B” (the
        “Contract Area”) and, except as otherwise provided for herein, all operations
        conducted on the Contract Area shall be governed by the terms and provisions contained in
        the May 1, 2005 Joint Operating Agreement to be amended to reflect the Contract Area and
        ratified contemporaneously herewith, the (“JOA”) or (“Operating
        Agreement”). Helis has been designated as Operator with Houston, et al as
        Non-Operators. The Operating Agreement shall be a covenant running with the land and all
        working interest owners participating in any aspect of the operations for drilling,
        completing or producing of any well on the Prospect shall be a party to the Operating
        Agreement. In the event of any conflict between the terms of this Agreement and those
        contained in the Operating Agreement, the terms and provisions of this Agreement shall at
        all times and in all events prevail, control and govern between the Parties hereto, with
        the non-conflicting terms and provisions of the Operating Agreement continuing in full
        force and effect. The presence of a term governing conduct in the Operating Agreement and
        the absence of a term governing the same conduct in this Agreement shall not constitute a
        conflict between the agreements.

        
        

        

        ARTICLE
        II:  AREA OF MUTUAL INTEREST (“AMI”)

        

        
                The
        Parties hereto establish the area encompassing all of the lands located within the
        geographic boundaries of the area depicted and outlined on the attached Exhibit
        “B”, as an AMI and, and unless sooner terminated by mutual agreement of the
        parties hereto, this designated AMI shall remain in full force and effect for so long as
        any of the Lease remain or are continued in force, whether by production, extension,
        renewal, or otherwise, plus one year.

        

        
                Any
        Party acquiring any leasehold interest or a contractual right to earn a leasehold interest
        within the AMI during the term above stated shall furnish the other Parties actual copies
        of the lease, leases, or documents used in acquiring said interest, documentation of the
        actual consideration paid or to be paid for said interest, and any other document pertinent
        to the other Parties evaluating the acquiring Party’s interest. The non-acquiring
        Parties shall have thirty (30) days or forty-eight (48) hours in the case where a well is
        in the process of being drilled, tested or completed by one or more of the Parties within
        the AMI, following receipt of such notice in which to elect, as to their respective
        proportionate after Production Casing Point share, as set forth and outlined in Article V
        hereof, to participate in the acquired interest. Such election shall be by written response
        to the acquiring Party accompanied by a check covering its share of the acquisition costs.
        Failure of a Party to reply within the above-specified period of time shall constitute an
        election not to participate in such acquisition.

        

        
                Any
        interest offered under this provision shall be offered without any additional burdens and
        at the same net revenue interest as acquired by the offering Party, except that, any
        interest acquired in the AMI by any Party shall be subject to the HE&D Burden, as
        hereinafter defined, and the acquiring Party of any interest in the AMI shall promptly
        assign to Houston Energy, L.P, or its designee, such HE&D Burden, if it does not
        already burden the interest acquired.

        

        ARTICLE III: 
        HE&D Burden

        

        
                In
        addition to the royalty burden the interests of the Parties are subject to a proportionate
        overriding royalty interest and back-in after payout, the (“HE&D Burden”)
        in favor of HE&D Offshore, L.P. as described in this Article III. As used herein below,
        “HE&D” shall refer to HE&D Offshore, L.P. or its designees, and
        “Leasehold Interest” and “Lease” or “Leases” shall
        refer to the Leases. The additional burdens are described as follows:

        2

        
        

        

        
                HE&D
        and its assigns are entitled to the right to or have heretofore been provided an assignment
        of a proportionate 5.333% overriding royalty interest applicable to the Leases. The
        overriding royalty interest shall be a burden on all proceeds received from the sale of all
        liquid or gaseous hydrocarbon substances produced, saved and marketed from or attributable
        to the Leasehold Interest. Said overriding royalty interest shall be proportionately
        reduced to the Party’s interest acquired and further reduced in the event the
        interest shall cover and include less than the full and complete fee interest in and to all
        oil, gas and hydrocarbons in, on and under the lands covered by the Lease, or should the
        leasehold rights, titles and interest in the Lease fail or terminate, in whole or in part
        for whatever reason, and shall be computed and paid at the same time and in the same manner
        as royalties are computed and paid to the Lessor under the terms of said Lease, except as
        hereinafter provided; and

        

        
                HE&D
        is entitled to an assignment proportionately from each Participant of a 10% working
        interest after Prospect Payout in and to the Leasehold Interest acquired by the
        Participants herein. “Prospect Payout” as used herein shall be defined as that
        point in time when each Participant in the acquisition and development of the Lease or
        Leasehold Interest has recouped from its share of the total value of production from the
        Lease (after deduction of production taxes, excise taxes, lessor’s royalty, existing
        lease burdens and HE&D’s overriding royalty) its share of the cost of drilling,
        testing, completing, equipping and operating all wells, the costs of all platforms,
        production facilities, pipelines, flowlines and other equipment necessary to produce the
        same, any bonus, rentals or other payments made to appropriate parties for the rights to
        such lease and production, less any proceeds received for the sale of interest pursuant to
        this agreement; and

        

        
                In
        addition to the royalty burden and the HE&D Burden as set forth above, Block 82 is
        burdened by a one percent (1%) overriding royalty interest in favor of Dominion Exploration
        & Production, Inc., (“Dominion”) pursuant to that certain Letter Agreement
        dated April 19, 2007 between Helis and Dominion. The Dominion override shall be treated in
        the same manner as the override payable to HE&D.

        

        ARTICLE IV: 
        ASSUMPTION OF OBLIGATIONS AND ASSIGNMENT OF INTEREST

        

        
                By
        execution of this Agreement, Ridgewood shall assume its ACP proportionate share of the
        rights and obligations contained in the Leases, and shall pay its ACP proportionate share
        of the sunk acquisition cost and maintenance of the leases for Blocks 79 and 82
        proportionately to the selling Parties. Ridgewood shall pay the amount of $44,008.36
        ($1,100,209 X 4%) to Houston and $275,052.25 ($1,100,209 X 25%) to Helis. Such payments
        shall be made upon execution of this Agreement by wire transfer of immediately available
        funds. Thereafter, not later than 15 days from receiving said payment from Ridgewood or
        after receipt of the assignment from Dominion, Houston and Helis shall assign or cause to
        be assigned to Ridgewood an undivided 29% interest in and to the Leases. The proportionate
        net revenue applicable to the Leasehold Interest after consideration of the burdens in
        Block 79 is 78% and the proportionate net revenue applicable to the Leasehold Interest
        after consideration of the burdens in Block 82 is 77%. The same proportionate net revenue
        shall apply to the Ridgewood interest after payout. Such assigned interest shall be subject
        to its proportionate share of existing Lease burdens (inclusive of the HE&D Burden and
        the Dominion orri). The assignment shall be made without any warranties or representations,
        express or implied, except that the assignors shall warrant title to the leasehold
        interests assigned by, through and under them, but not otherwise. Helis currently has the
        responsibilities for lease maintenance as Operator of the Leases and shall continue for the
        benefit of all the Parties.

                    Subject
                    to permitting and rig availability, Helis, as Operator, shall use commercially

                    Exhibit “C”, the “Initial Test Well”.

                

        

        

        	2. 	

                    The
                    Parties agree to bear and pay their proportionate share as set forth below of
                    all the cost, risk, expense and liability of any nature whatsoever incurred in
                    the drilling, testing, logging, coring and evaluating the Initial Test Well
                    (including plugging and abandonment costs, if a dry hole), subject to the AFE

                    Production Casing Point is
                    defined herein as that point when the Initial Test Well has been drilled to
                    Contract Depth and all logging, testing and evaluations have been conducted,
                    and such information has been provided to the participating parties and the
                    Operator recommends either that production casing be set for a completion
                    attempt or that the well be plugged and abandoned, and through plugging and
                    abandonment, if no completion attempt shall be made.

                    After
                    Prospect Payout, as hereinabove defined, HE&D, or its designee, shall be
                    entitled to receive from each participating Party a proportionate 10% back-in
                    working interest.

                

        

        

        	
                3. 	
                    If the
                    well provided for herein should fail to reach Contract Depth due to mechanical
                    difficulties or because the well encounters excessive water flow, loss of
                    circulation, excessive pressure, cavities, caprock, salt or salt dome material,
                    heaving shale, or other practically impenetrable conditions which would, in the
                    opinion of a prudent operator, render further drilling impracticable, then the
                    Parties may, at their election, commence, or cause to be commenced, actual
                    drilling of a substitute well at approximately the same location within sixty
                    (60) days after abandonment of said well. The substitute well shall be
                    considered and treated for all purposes hereof as though the same were the well
                    for which it is a substitute.

                    All
                    participating Parties or their duly authorized representatives shall be allowed
                    free access to the derrick floor at their sole risk and expense and to any and
                    all information, geological or otherwise, pertaining to the drilling of any
                    well, substitute well and/or additional well. Prior to running any logging
                    device, coring or taking any formation test or other similar type test, Helis
                    shall first give all Parties notice in sufficient time to allow their
                    representative to be present to witness such test. Helis agrees to furnish each
                    Party all information associated with the drilling of the well and its
                    operations thereof according to each Party’s well information
                    sheet.

        FORCE MAJEURE

        

        
                No
        Party hereto shall be liable to any other Party, its subsidiaries or affiliates or any
        person, firm, or corporation in privity with such other Party, its subsidiaries or
        affiliates, for any delays or damage or any failure to act hereunder (except for the
        payment of monies due) that may be occasioned or caused by reason of any laws, rules,
        regulations or orders promulgated by any federal, state or local governmental agency or any
        court of law or by the rules, regulations or orders of any public body or official
        purporting to exercise authority or control respecting the activities and operations
        contemplated herein, or due, occasioned or caused, directly or indirectly, by strikes,
        action of the elements, acts of God, weather or water conditions, inability to obtain fuel,
        equipment or other critical materials, means or supplies, or any other cause beyond the
        reasonable control of the non-performing Party (excluding financial distress or inability
        to pay debts when due). In the event of the occurrence of any of the foregoing, the
        obligations of the non-performing Party shall be suspended during the continuance of any
        such event or condition, and the time permitted for performance under this Agreement shall
        be extended for a period of time equal to the period of such suspension. Whenever a
        Party’s obligations or right is suspended under this Article, such Party shall
        immediately notify the other Parties, give written explanation for the cause of Force
        Majeure relied on and exercise reasonable best efforts to cure the cause of the Force
        Majeure relied on and to resume performance.

        

        ARTICLE VII: 
        MARKETING

        

        
                The
        Parties intend to make arrangements with the Operator (Helis) for the equal and ratable
        marketing of their share of the production from the Lease, however, if any Party fails to
        take in kind or dispose of its share of the oil, condensate or gas, then at the request of
        such Party, Helis will market that Party’s share of production from the Contract Area
        ratably with their own production in a manner maintaining as near as practicable a zero gas
        imbalance at the end of each production month. Helis may either (a) purchase oil,
        condensate or gas at Helis’ posted price or, in the absence of a posted price, in no
        event less than the price prevailing in the area for oil or gas of the same kind, gravity
        and quality, or (b) sell such oil, condensate or gas to others under the same terms and
        conditions as Helis is selling its own share of production (including any applicable taxes,
        fees and costs deducted by the purchaser or transporter or paid to third parties for
        marketing arrangements and consultation), provided that if the production is sold to an
        affiliate of Helis the price received shall not be less than the price prevailing in the
        area for oil or gas of the same kind, gravity and quality. All contracts of sale by Helis
        of any Party’s share of oil, condensate or gas shall be only for such reasonable
        periods of time as are consistent with the minimum needs of the industry under the
        circumstances, but in no event shall any contract be for a period in excess of one (1)
        year. Proceeds of all sales made by Helis pursuant to this Section shall be paid to the
        Parties entitled thereto. At the request of any Party, Helis shall disburse on behalf of
        such Party all burdens common to the Parties.

                    1.      
                    Dispute Resolution. Any controversy, claim or other proceeding arising out
                    of or relating to this Agreement, the validity, interpretation or the
                    enforcement of this Agreement or because of an alleged dispute, breach,
                    default, or misrepresentation in connection with this Agreement or the
                    transactions contemplated hereby shall be settled by arbitration in accordance
                    with the provisions set forth in the Exhibit “G” of the Operating
                    Agreement. Each Party to this Agreement waives any and all claims for treble,
                    punitive or exemplary damages arising out of or relating to this
                    Agreement.

                

        

        

        	 	
                    
                    2.     
                    Further Assurances. The Parties hereto shall, from time to time and upon
                    reasonable request, execute, acknowledge, and deliver, or cause to be executed,
                    acknowledged, and delivered, such instruments, and take such other action, as
                    may be necessary or advisable, to carry out their respective obligations under
                    this Agreement.

                

        

        

        	 	
                    
                    3.     
                    Assignment of Agreement. No Party shall assign this Agreement or any of
                    its rights or obligations under this Agreement without obtaining the prior
                    written consent of the other Parties, which consent shall not be unreasonably
                    withheld.

                

        

        

        	 	
                    
                    4.     
                    Compliance with Laws and Regulations. This Agreement, and all operations
                    conducted by the Parties pursuant to this Agreement, are expressly subject to
                    and shall comply with all laws, orders, rules, and regulations of any federal,
                    state, or local governmental authority having jurisdiction. No Party shall
                    suffer forfeiture or be liable in damages for failure to comply with any of the
                    provisions of this Agreement if such compliance is prevented or if such failure
                    results from compliance with any applicable law, order, rule, or
                    regulation.

                

        

        

        	 	
                    
                    5.     
                    Applicable Law. THE PROVISIONS OF THIS AGREEMENT AND THE RELATIONSHIP OF
                    THE PARTIES SHALL BE GOVERNED AND INTERPRETED ACCORDING TO THE LAWS OF THE
                    STATE OF LOUISIANA WITHOUT GIVING EFFECT TO PRINCIPLES OF CONFLICTS OF
                    LAWS.

                

        

        

        	 	
                    
                    6.     
                    Severance of Invalid Provisions. In case of a conflict between the
                    provisions of this Agreement and the provisions of any applicable laws or
                    regulations, the provisions of the laws or regulations shall govern over the
                    provisions of this Agreement. If, for any reason and for so long as, any clause
                    or provision of this Agreement is held by a court of competent jurisdiction to
                    be illegal, invalid, unenforceable, or unconscionable under any present or
                    future law (or interpretation thereof), the remainder of this Agreement shall
                    not be affected by such illegality or invalidity. Any such invalid provision
                    shall be deemed severed from this Agreement as if this Agreement had been
                    executed with the invalid provision eliminated. The surviving provisions of
                    this Agreement shall remain in full force and effect unless the removal of the
                    invalid provision destroys the legitimate purposes of this Agreement, in which
                    event this Agreement shall be null and void. The Parties shall negotiate in
                    good faith for any required modifications to this Agreement.

                    7.     
                    Construction and Interpretation. The interpretation and construction of
                    the terms of this Agreement will be governed by the following
                    conventions:

                

        

        

        	
                (i) 	
                  	
                
                Headings for Convenience: All captions, numbering sequences, paragraph headings,
                and punctuation used in this Agreement are inserted for convenience only and shall
                in no way define, limit, or describe the scope or intent of this Agreement or any
                part thereof.
 

        

        

        	
                (ii) 	
                  	
                
                Gender and Number: The use of pronouns in whatever gender or number shall be deemed
                to be a proper reference to the Parties to this Agreement though the Parties may be
                business entities or groups thereof. Any necessary grammatical changes required to
                make the provisions of this Agreement refer to the correct gender or number shall
                in all instances be assumed as though each case was fully expressed.
 

        

        

        	
                (iii) 	
                  	
                
                Independent Representation: Each Party has had the benefit of independent legal
                representation with respect to this Agreement. This Agreement, though drawn by one
                Party, shall be construed fairly and reasonably and not more strictly against one
                Party than the other.
 

        

        

        	
                (iv) 	
                  	
                    Integrated
                    Agreement: This Agreement, and the Exhibits attached and incorporated herein,
                    contain the entire agreement of the Parties with respect to the subject matter
                    of this contract. There are no representations, warranties, or promises; oral
                    or written, express or implied, between the Parties other than those included
                    in this Agreement and the Exhibits hereto. Each of the Parties acknowledges
                    that the other Party has made no promise, representation, or warranty that is
                    not expressly stated or incorporated in this Agreement or the Exhibits hereto.
                    This Agreement shall not be modified or changed (nor any provision of this
                    Agreement waived) except by a written amendment signed by all Parties. This
                    Agreement is the entire agreement as to all of the performances to be rendered
                    under it, and breach of any provision shall constitute a breach of the entire
                    Agreement. A waiver of any breach or failure to enforce any of the terms or
                    conditions of this Agreement shall not in any way affect, limit, or waive a
                    Party’s rights under this Agreement at any time to enforce strict
                    compliance thereafter with every term or condition of this
                    Agreement.

                    8.     
                    Binding Effect: The terms and provisions of this Agreement shall inure
                    to the benefit of, and shall be binding upon, the Parties, their respective
                    successors and permitted assigns. The Parties agree to execute such other
                    instruments as may be necessary to carry out or make effective the terms and
                    provisions of this Agreement.

                

        

        

        	 	
                    
                    9.     
                    Relationship of the Parties: The rights and obligations of the Parties
                    hereunder shall be individual, separate, and several and not joint and
                    collective. It is expressly agreed that The Parties do not intend to create,
                    and it is not the purpose or intention of this Agreement to create, and this
                    Agreement shall never be construed as creating, a joint venture, mining
                    partnership, or other relationship whereby any Party will be liable for the
                    acts, either of omission or commission, of any other Party hereto. Each of the
                    Parties hereby elects to have the Secretary of the Treasury of the United
                    States, or his delegate, exclude all operations provided for in this agreement
                    from the application of any of the provisions of Subtitle A, Chapter 1,
                    Sub-chapter K of the Internal Revenue Code of 1986 as amended, and, further
                    each of such parties authorize the operator of the well hereunder to file with
                    the Internal Revenue Service such documents, statements and copies of this
                    agreement, as may be necessary or desirable to effect such exclusions of the
                    Internal Revenue Code of 1986, as amended.

                

        

        

        	 	
                    
                    10.   
                    Counterpart Execution: This Agreement may be executed by signing the
                    original or a counterpart thereof. If this Agreement is executed in
                    counterparts, all counterparts taken together shall have the same effect as if
                    all Parties had signed the same agreement, but no Party shall be bound to this
                    Agreement unless and until all Parties have executed a counterpart or the
                    original.

                

        

        

        
                    
        IN WITNESS WHEREOF, the Parties have executed or caused the Agreement to be executed as of
        the day and year first above written.

                          MANAGEMENT SERVICES AGREEMENT
                          -----------------------------

THIS MANAGEMENT SERVICES AGREEMENT (this "Agreement") dated as of the 14th day
of April, 2008, between ReEnergy Advisory Group LLC, having an address at 133
Darroch Road, Delmar, New York 12054 ("ReEnergy"), and World Waste Technologies,
Inc., having an address at 13500 Evening Creek Drive North, Suite 440, San
Diego, California 92128 ("WDWT").

                              W I T N E S S E T H :

For good and valuable consideration, the receipt and sufficiency of which is
hereby acknowledged, the parties hereby agree as follows:

1.    SCOPE OF SERVICES. WDWT and ReEnergy agree that ReEnergy will be
      responsible for implementing all of the activities relating to WDWT's
      biomass renewable energy business, which will include performing the
      services generally described on Exhibit A hereto. While the parties
      acknowledge that ReEnergy will continue its other activities during the
      term of this Agreement (subject to the provisions of Section 14 below), it
      is understood that ReEnergy's principals will commit at least an aggregate
      of approximately 250 hours per month to WDWT's business activities.
      ReEnergy will also provide such additional services for WDWT as are agreed
      to from time to time by the parties in writing.

2.    REPORTING. ReEnergy will report to, and take direction from, the CEO and
      Board of Directors of WDWT. ReEnergy will update the CEO and Board of
      Directors of WDWT on a periodic basis regarding ReEnergy's activities
      hereunder, and at any time upon request of the Board. Within 30 days after
      the date of this Agreement, ReEnergy will work with existing WDWT
      resources to develop and present a formal business plan for review and
      approval by WDWT's Board of Directors.

3.    FEES FOR SERVICES. So long as this Agreement is in effect, WDWT will pay
      ReEnergy a monthly retainer of $35,000 to be applied to the services of
      ReEnergy's principals (Larry Richardson, Tom Beck and Bill Ralston) under
      this Agreement for up to an aggregate of 250 hours each month. Payments
      for any partial month shall be appropriately pro rated. In the event said
      individuals provide more than an aggregate of 250 hours of services under
      this Agreement in any month, WDWT will pay ReEnergy for such excess hours
      at the rate of $150 per hour. In addition, WDWT will pay ReEnergy for any
      services provided by its senior advisors (Greg Leahey and Amy Welsh) under
      this Agreement at the rate of $130 per hour. Notwithstanding the
      foregoing, ReEnergy agrees that (i) no more than 40 hours per week will be
      charged to WDWT for any of ReEnergy's principals or senior advisors, and
      (ii) the total labor charges in any month for its principals and senior
      advisors will not exceed $60,000 (inclusive of the retainer payment)
      without WDWT's prior written approval.. WDWT will also reimburse ReEnergy
      for all reasonable out-of-pocket expenses incurred by ReEnergy in
      connection with the performance of its services (provided that any expense
      over $1,500, other than travel expenses, shall require WDWT's prior
      written approval). Upon request of WDWT, ReEnergy will provide appropriate
      supporting documentation for all reimbursable expenses.

<page>

      On the date hereof, and on the first day of each month hereafter during
      the term of this Agreement, WDWT will pay ReEnergy the monthly retainer
      described above. ReEnergy will submit monthly invoices to WDWT for any
      fees due for the services of its principals in excess of 250 hours in any
      month and the services of its senior advisors, setting forth the number of
      hours worked per week per individual (subject to the 40-hour per person
      per week limitation), and the reimbursable expenses incurred in such month
      (provided that in no event will the amount due on any invoice attributable
      to such fees exceed $25,000 in any month without WDWT's prior written
      approval). WDWT will pay each such invoice within 20 days of receipt
      thereof. If ReEnergy does not receive payment of the monthly retainer
      within 20 days after the first day of the month for which such payment is
      due, or for any invoice for the other amounts described above within 20
      days after WDWT's receipt thereof, the amount due will bear interest at
      the rate of 1.5% per month or the highest rate that may then be lawfully
      charged, whichever is less, from the date such payment was due.

4.    INDEPENDENT CONTRACTOR. ReEnergy is an independent contractor of WDWT.
      ReEnergy shall not be deemed to be an agent of WDWT, and shall not have
      the authority to enter into any agreements on behalf of WDWT. ReEnergy's
      services under this Agreement are solely for the benefit of WDWT, and
      nothing contained in this Agreement shall be deemed to create any duty on
      the part of ReEnergy to any other party.

5.    WORKS. (a) WORKS RETAINED AND LICENSED. ReEnergy represents that it has no
      inventions, processes, designs, algorithms, methods, techniques,
      discoveries, formulae, code or computer software which were made by it
      prior to its engagement with WDWT (collectively referred to as "Prior
      Works"), which belong to it and which relate to WDWT's current business,
      products or research and development. If in the course of its engagement
      with WDWT, ReEnergy incorporates into any WDWT product, process or machine
      a Prior Work owned by it or in which it has an interest, WDWT is hereby
      granted and shall have a nonexclusive, royalty-free, irrevocable,
      perpetual, worldwide license to make, have made, modify, revise, reverse
      decompile, use and sell such Prior Work as part of or in connection with
      such product, process or machine or for any other purpose of any kind or
      nature for which WDWT seeks to utilize such Prior Works.

(b)   WORK MADE FOR HIRE. All original inventions, production processes,
      products, processes, designs, algorithms, methods, techniques,
      discoveries, formulae, code or computer software, whether or not
      patentable or registrable under copyright, trademark or similar laws),
      which are or have been conceived, prepared, created, composed, developed,
      or reduced to practice, in whole or in part by ReEnergy and/or by other
      contributors at any time in connection with any and all work commissioned,
      conceived, prepared, created, composed, or developed by or for ReEnergy or
      within the scope of its engagement with WDWT (all of the foregoing,
      collectively, "Works") (i) was intended at all times prior to its creation
      to constitute, (ii) since its creation has constituted and (iii) shall in
      the future constitute, a "work made for hire" for WDWT and WDWT shall
      forever be deemed the exclusive owner thereof, and has and shall have any
      and all right, title, and interest of any kind or nature in and to the
      Works (the "Rights").

                                       2

(c)   ASSIGNMENT, FURTHER EXECUTION AND ASSISTANCE. Notwithstanding the
      foregoing, if for any reason the Works (or any portion thereof heretofore
      or hereafter created) is not deemed a "work made for hire" or if under any
      applicable law the fact that the Works is a "work made for hire" is not
      effective to place ownership of the Works and all rights therein in WDWT,
      in consideration of its engagement by WDWT and other good and valuable
      consideration, the receipt and adequacy of which is hereby acknowledged,
      ReEnergy hereby assigns and transfers to WDWT in perpetuity the Works and
      all Rights therein and in any other works now or hereafter created
      containing the Works, without reservation, condition or limitation, and no
      right of any kind, nature or description is reserved by ReEnergy. If WDWT
      shall desire to secure separate assignments of or for any of the
      foregoing, or if WDWT shall desire further documents that it deems
      reasonably necessary to protect any of the Rights in the Works in any and
      all countries, ReEnergy shall execute and shall cause any contributors
      engaged by ReEnergy to execute the same upon WDWT's request.

(d)   REPRESENTATIONS, WARRANTIES AND COVENANTS. ReEnergy represents and
      warrants that the Works have been, is and will be wholly original with
      ReEnergy and not copied in whole or in part from, or based on, any other
      work except that submitted to ReEnergy by WDWT as a basis for the Works,
      if any, or material in the public domain. ReEnergy further represents and
      warrants that the Works have not, does not and will not infringe upon the
      copyright or otherwise violate any Rights of any person, firm or
      corporation. ReEnergy hereby represents, warrants, and covenants that it
      does not have, shall not have or be deemed to have any lien, charge or
      other encumbrance upon any of the Works or Rights conveyed to WDWT herein
      or proceeds derived therefrom, and that no act of or omission by WDWT, nor
      any other act, omission or event of any kind, shall terminate or otherwise
      adversely affect WDWT's ownership of the Works or Rights. ReEnergy shall
      indemnify and hold WDWT, and its successors, licensees and assigns
      harmless from and against all damages, losses, costs and expenses
      (including reasonable outside attorneys' fees and costs) which WDWT, or
      any of its successors, licensees or assigns may suffer or incur by reason
      of the breach of any of ReEnergy's representations or warranties
      hereunder.

6.    RETURN OF WDWT PROPERTY. ReEnergy agrees that at the time its engagement
      by WDWT ends, it will deliver to WDWT (and will not keep in its
      possession, recreate or deliver to anyone else) any and all property of
      WDWT, and all Confidential Information (as defined in the NDA), received
      by ReEnergy pursuant to its engagement with WDWT or otherwise belonging to
      WDWT, its successors or assigns.

7.    SOLICITATION OF EMPLOYEES. ReEnergy agrees that during the term of this
      Agreement and for a period of twelve (12) months immediately following the
      termination of ReEnergy's relationship with WDWT for any reason, it shall
      not either directly or indirectly solicit, induce, recruit or encourage
      any of WDWT's employees to leave their employment, either for their own
      employment or engagement or for any other person or entity.

8.    REENERGY RESPONSIBLE FOR ITS AGENTS AND EMPLOYEES. ReEnergy shall select
      and shall have full and complete control of and responsibility for all
      agents, employees and subcontractors employed or used by ReEnergy and for
      the conduct of ReEnergy's independent business and none of said agents,
      employees or subcontractors shall be, or shall be deemed to be, the agent,
      employee or subcontractor of WDWT for any purpose whatsoever, and WDWT
      shall have no duty, liability or responsibility, of any kind, to or for
      the acts or omissions of ReEnergy or such agents, employees or
      subcontractors, or any of them.

                                       3

9.    REENERGY RESPONSIBLE FOR TAXES AND INDEMNIFICATION. Without limiting any
      of the foregoing, ReEnergy agrees to accept exclusive liability for the
      payment of taxes or contributions for unemployment insurance or old age
      pensions, annuities or social security payments, or other statutory
      employer obligations or contributions which are measured by the wages,
      salaries or other remuneration paid to ReEnergy or the employees of
      ReEnergy and to reimburse and indemnify WDWT for such taxes or
      contributions or penalties which WDWT may be compelled to pay. ReEnergy
      also agrees to comply with all valid administrative regulations respecting
      the assumption of liability for such taxes and contributions.

10.   ARBITRATION AND EQUITABLE RELIEF. (a) Arbitration. Except as provided in
      Section 10(b) below, it is agreed that any dispute or controversy arising
      out of or under or relating to this Agreement or any interpretation,
      construction, performance or breach thereof or otherwise arising out of or
      relating to this engagement or its termination shall be settled by
      arbitration to be held before a single arbitrator in accordance with the
      Arbitration Rules then in effect of the American Arbitration Association.
      The arbitrator may grant injunctions or other relief in such dispute or
      controversy. The decision of the arbitrator shall be final, conclusive and
      binding on the parties to the arbitration. Judgment may be entered on the
      arbitrator's decision in any court having jurisdiction. Unless otherwise
      provided by statute, WDWT and ReEnergy shall each pay one-half of the
      costs and expenses of such arbitration, and each shall separately pay its
      own counsel fees and expenses.

(b)   Equitable Remedies. ReEnergy agrees that it would be impossible or
      inadequate to measure and calculate WDWT's damages from any breach of the
      covenants set forth in Sections 5, 6, or 7 herein. Accordingly, ReEnergy
      agrees that if it breaches any of such Sections, WDWT will have available,
      in addition to any other right or remedy available, the right to obtain an
      injunction from a court of competent jurisdiction restraining such breach
      or threatened breach and to specific performance of any such provision of
      this Agreement. ReEnergy further agrees that no bond or other security
      shall be required in obtaining such equitable relief and ReEnergy hereby
      consents to the issuance of such injunction and to the ordering of
      specific performance.

11.   STANDARD OF CARE. ReEnergy will perform services under this Agreement with
      the degree of skill and diligence normally practiced by consultants
      performing the same or similar services in the renewable energy and waste
      management industries. Except as specifically set forth in this Agreement,
      no warranty or guarantee, express or implied, is made with respect to the
      services to be provided by ReEnergy under this Agreement. Without limiting
      the foregoing, WDWT acknowledges that ReEnergy does not control the cost
      of labor, materials, equipment or services provided by third parties, and
      any estimates of operating or capital costs prepared by ReEnergy represent
      its best judgment and are not a guarantee of costs.

12.   REPERFORMANCE OF SERVICES; LIMITATION OF LIABILITY. If WDWT believes that
      the services provided by ReEnergy hereunder do not comply with the terms
      of this Agreement, WDWT will promptly notify ReEnergy in writing
      describing the manner in which ReEnergy's services are non-compliant. If
      the services do not meet the applicable standard of care, ReEnergy will
      promptly reperform the deficient services at no additional cost to WDWT.

                                       4

      If WDWT fails to provide ReEnergy with said notice and the opportunity to
      reperform said services, ReEnergy's total liability to WDWT will be
      limited to the costs ReEnergy would have incurred to reperform the
      services.

      The total aggregate liability of ReEnergy for any and all claims arising
      out of this Agreement, including attorneys' fees, and whether arising from
      breach of contract, negligence, indemnity claims, strict liability or
      otherwise, shall not exceed the fees paid to ReEnergy hereunder or
      $100,000, whichever is greater. Furthermore, in no event shall ReEnergy be
      liable to WDWT for any consequential, special, indirect or incidental loss
      or damages by reason of any breach hereunder or otherwise in connection
      with this Agreement.

13.   CONFIDENTIAL INFORMATION. The parties agree that the Mutual Non-Disclosure
      Agreement dated as of January 1, 2008 (the "NDA") executed by the parties
      shall apply to the services to be performed by ReEnergy under this
      Agreement.

14.   CONFLICTING EMPLOYMENT. ReEnergy agrees, on behalf of itself and its
      principals and advisors, that, during the term of its engagement with
      WDWT, neither it nor any of its principals or advisors will engage in any
      other employment, occupation, consulting or other business activity
      competitive with WDWT's current renewable energy business, nor will it or
      any of them engage in any other activities that conflict with it or their
      obligations under this Agreement.

15.   INDEMNITY. ReEnergy agrees to indemnify and hold WDWT harmless from and
      against any liability, including reasonable attorneys' fees, incurred by
      WDWT to the extent caused by ReEnergy's, or any of its employee's or
      subcontractor's, negligence or willful misconduct in connection with the
      performance of services under this Agreement. WDWT agrees to indemnify and
      hold ReEnergy harmless from and against any liability, including
      reasonable attorneys' fees, incurred by ReEnergy in connection with the
      performance of services under this Agreement to the extent caused by
      WDWT's negligence or willful misconduct.

16.   TERMINATION. This Agreement may be terminated by either party at any time
      upon 10 days written notice to the other party. This Agreement will
      terminate on May 31, 2008 unless prior to such date the parties agree to
      extend the term WDWT will pay ReEnergy for all services rendered up to the
      date of termination of this Agreement. In addition to the foregoing, if at
      any time either party defaults in its obligations hereunder, the
      non-defaulting party may, after giving 10 days written notice of its
      intent to do so, either suspend performance under this Agreement until
      said default is cured, or terminate this Agreement unless such default is
      cured within said 10 day period, and the taking of either of such actions
      shall not in any way impair the rights of the non-defaulting party with
      respect to such default.

17.   MISCELLANEOUS PROVISIONS.

      This Agreement is binding upon, and shall inure to the benefit of, WDWT
      and ReEnergy and their respective successors and assigns. Neither party
      may assign its rights or obligations under this Agreement without the
      prior written consent of the other party.

                                       5

      Notices and all other communications provided for in this Agreement shall
      be in writing, shall be deemed to have been given when received, and shall

      receipt, in each case addressed to WDWT, Attention: CEO, or to ReEnergy at

      time the party knew or should have known of the fact giving rise to its
      action.

      In the event that any of the provisions of this Agreement are held to be
      unenforceable or invalid by any court of competent jurisdiction, ReEnergy
      and WDWT shall negotiate an equitable adjustment to the provisions of this
      Agreement with a view toward effecting the purpose of this Agreement, and
      the validity and enforceability of the remaining provisions hereof shall
      not be affected thereby.

      This Agreement may be executed in multiple counterparts, each of which
      shall be deemed to be an original instrument, and all of which taken
      together shall be deemed to constitute one instrument.

IN WITNESS WHEREOF, the parties hereto have executed this Agreement as of the
date first above written.
