the Transferred Equipment.

         1.7. CONSEQUENCES OF FAILURE TO CLOSE. Failure to consummate any of the
transactions provided for in this Agreement on the dates and at the place
determined pursuant to this Article 1 will not result in the termination of this
Agreement and will not relieve any party of any obligation under this Agreement.

                                    ARTICLE 2

                      REPRESENTATIONS AND WARRANTIES OF WWT

         In order to induce CES to enter into and perform this Agreement, WWT
hereby represents and warrants to CES, as of the date hereof and as of each of
the First, Second and Third Closing Dates, as follows:

cancel (a) any provision of the Articles of Incorporation or Bylaws of WWT or
the charter documents of any Subsidiary of WWT, as currently in effect, (b) in

any permit used in or necessary for the conduct of WWT's or any Subsidiary's
business. The consummation by WWT of the sale of the Transferred Equipment and
Transferred IP will not require the consent, approval or authorization of, or
declaration, filing or registration with, any third party.

part of CES necessary for the authorization, execution, delivery and performance
of this Agreement and the CES Ancillary Agreements, the consummation of the
purchase of the Transferred Equipment and Transferred IP, and the performance of

         3.3. NO VIOLATION OF EXISTING AGREEMENTS; THIRD PARTY CONSENTS AND
APPROVALS. Neither the execution and delivery of this Agreement nor any CES
Ancillary Agreement, nor the consummation of the transactions contemplated
hereby or thereby, will conflict with, or (with or without notice or lapse of
time, or both) result in a termination, breach, impairment or violation of (a)
any provision of the Articles of Incorporation or Bylaws of CES or the charter

respect, any material instrument or contract to which CES or any Subsidiary of

with, any third party.

         3.4. WWT DISCLOSURE. Except for the representations and warranties
expressly made by WWT in this Agreement, CES agrees and acknowledges that WWT
has not made any representations or warranties concerning the Transferred
Equipment or Transferred IP, WWT, or any of its assets, liabilities, financial
condition, business or operations, or any other matter.

         3.5. DISCLAIMER. EXCEPT AS OTHERWISE EXPRESSLY PROVIDED IN THIS
AGREEMENT, THE TRANSFERRED EQUIPMENT AND TRANSFERRED IP ARE BEING SOLD TO CES
"AS IS" AND WWT EXPRESSLY DISCLAIMS ALL REPRESENTATIONS AND WARRANTIES, EXPRESS
AND IMPLIED, INCLUDING, WITHOUT LIMITATION, THOSE OF PERFORMANCE,
NONINFRINGEMENT, MERCHANTABILITY AND SUITABILITY AND FITNESS FOR ANY PARTICULAR
PURPOSE OR USE. WITHOUT LIMITING THE GENERALITY OF THE FOREGOING, AND BY WAY OF
EXAMPLE AND NOT LIMITATION, CES ACKNOWLEDGES THAT THE AUTOCLAVE DRIVE SYSTEM
INCLUDED IN THE TRANSFERRED EQUIPMENT REQUIRES A RE-BUILD, AND THAT SIGNIFICANT
EXPENDITURES ARE REQUIRED WITH RESPECT TO ELECTRICAL AND CONTROL SYSTEMS (ALL OF
WHICH EXPENDITURES SHALL BE CES'S SOLE RESPONSIBILITY). ADDITIONALLY, WWT GIVES
NO ASSURANCE AS TO THE ACCURACY OR COMPLETENESS OF ANY OF THE INFORMATION
CONTAINED IN THE AUTOCLAVE RE-ENGINEERING REPORT PACKAGE OR THE AUTOCLAVE
OPERATING/BIOMASS DATA PACKAGE.

                                    ARTICLE 4

                                    COVENANTS

         4.1. CERTAIN FILINGS; REASONABLE EFFORTS. Subject to the terms and
conditions herein provided, each of the parties hereto agrees to use
commercially reasonable efforts to take or cause to be taken all action and to
do or cause to be done all things reasonably necessary, proper or advisable
under applicable laws and regulations to consummate and make effective the
transactions contemplated by this Agreement, including executing any additional
instruments necessary to consummate the transactions contemplated hereby. WWT
shall deliver a Bill of Sale to CES at each of the First and Third Closings,
documenting the transfer of the Transferred Equipment and the Transferred IP,
respectively

         4.2. EQUIPMENT REMOVAL. The parties acknowledge that the dismantling of
the Transferred Equipment from the Facility will need to be completed and that
accordingly, CES will not be in physical possession of the Transferred Equipment
until following the First Closing. In this regard, the parties agree as follows:

                  (a) Following the First Closing, WWT will complete the
dismantling of the Transferred Equipment. WWT's obligations with respect to the
Transferred Equipment shall be limited to dismantling and loading the
Transferred Equipment onto a vehicle supplied by or on behalf of CES. CES shall
bear all costs in connection with transporting the Transferred Equipment.

                  (b) Title to the Transferred Equipment (and accordingly, risk
of loss) will transfer to CES as of the First Closing, despite the fact that
some of the Transferred Equipment may remain at the Facility for a period of
time following the First Closing.

         4.3. TERMINATION OF R & D. Effective as of the First Closing, WWT will
suspend, and, effective as the Third Closing, will terminate, any and all
research and development, whether being conducted by WWT or any third party
contracted by WWT, on (i) the PSC Process (U.S. Patent 6,306,248), or any
generally similar MSW autoclaving process, (ii) the conversion or applications
of the cellulose feedstock produced by the PSC Process (U.S. Patent 6,308,248),
or any generally similar autoclaving process; and (iii) any other intellectual
property being applied for by or on behalf of WWT (including patents, patents
pending, patent applications, copyrights, trademarks, etc.) relating to the PSC
Process itself, or any generally similar MSW autoclaving process; provided,
however, that nothing in this Section 4.3 or in any other provision of this
Agreement shall prohibit WWT from licensing or otherwise acquiring in the future
any autoclaving technology, including any MSW autoclaving process that is
similar to the PSC process. Nothing in this Agreement will affect or otherwise
limit WWT's rights with respect to any other research and development
activities, including, by way of example and not limitation, research activities
surrounding WWT's patent application on the formation of mixed alcohols from
syngas prepared from the gasification of biomass. In the event that the Third
Closing does not occur by June 15, 2008, WWT's obligations under this Section
4.3 shall terminate.

                                       6
<PAGE>

         4.4. PRESS RELEASE. Within four Business Days of the First Closing, WWT
will issue a press release announcing that it has entered into an agreement with
CES to sell to CES any and all interests WWT has in the PSC Process and the
cellulose biomass produced by the PSC Process. WWT will provide a draft of the
press release to CES for its review and shall include CES's reasonable comments
to the extent reasonably acceptable to WWT and its counsel from a securities law
perspective.

                                    ARTICLE 5

                                   TERMINATION

         5.1. TERMINATION EVENTS. This Agreement may, by notice given prior to
or at any Closing, be terminated with respect to the transactions contemplated
by such Closing:

                  (a) by either CES or WWT if a material breach of any provision
of this Agreement has been committed by the other party and such breach has not
been waived;

                  (b) by mutual consent of WWT and CES; or

                  (c) by either WWT or CES if such Closing has not occurred
(other than through the failure of any party seeking to terminate this Agreement
to comply fully with its obligations under this Agreement) on or before (i) the
date hereof, with respect to the First Closing; May 1, 2008, with respect to the
Second Closing; or June 15, 2008 with respect to the Third Closing, or such
later dates as the parties may agree upon.

         5.2. EFFECT OF TERMINATION. Each party's right of termination under
Section 5.1 is in addition to any other rights it may have under this Agreement
or otherwise, and the exercise of a right of termination will not be an election
of remedies. If this Agreement is terminated pursuant to Section 5.1 with
respect to any Closing, all further obligations of the parties under this
Agreement with respect to the Closing or Closings that have been so terminated
will terminate, except that the obligations in Article 6 will survive; provided,
however, that if this Agreement is terminated by a party because of the breach
of this Agreement by the other party (including, by way of example and not
limitation, the failure of CES to notify WWT of the Second Closing and to
deliver the Second Closing Payment on or before May 1, 2008, and the failure of
CES to notify WWT of the Third Closing and to deliver the Third Closing Payment
on or before June 15, 2008) or because one or more of the conditions to the
terminating party's obligations under this Agreement is not satisfied as a
result of the other party's failure to comply with its obligations under this
Agreement, the terminating party's right to pursue all legal remedies will

shall forever expire if written notice of such claim or legal action (along with
a detailed written notice of the alleged facts underlying such claim or action)
is not given to the other party before the end of such 12-month period. All of
the covenants and obligations of the parties contained in this Agreement or any
certificate or document delivered in accordance with the terms of this Agreement

such covenants or obligations is waived in writing by the party or parties
entitled to such performance or (ii) if not fully performed or fulfilled, until
the expiration of the relevant statute of limitations.

         6.2. POST-CLOSING INDEMNIFICATION PROVISIONS FOR BENEFIT OF CES.
Provided that CES makes a written claim for indemnification pursuant to this
Section before the expiration of the applicable time period set forth in Section
6.1, WWT shall indemnify CES, its Subsidiaries, and their respective officers,
directors and representatives (collectively, the "CES Indemnitees") from and
against, hold each of them harmless from, and reimburse each of them for, the
entirety of any Adverse Consequences which such CES Indemnitees actually suffer
through and after the date of the claim for indemnification directly resulting
from, arising out of, relating to, or caused by any breach by WWT of any of its
representations, warranties, covenants or obligations contained in this
Agreement or any certificate or document delivered in accordance with the terms
of this Agreement, or any schedule hereto or thereto.

         6.3. INDEMNIFICATION LIMITS. With respect to any and all claims for
which either party is entitled to indemnification under this Agreement, each
party shall be entitled to indemnification for the aggregate amount of all
Losses it actually incurs from the first dollar. Under no circumstances shall
either party's total liability for claims for indemnification under this
Agreement or breach of any representations or warranties exceed $500,000.
Notwithstanding the foregoing, the limitations with respect to Losses sustained
by WWT as a result of the breach by CES of its obligation to cause the Second
and/or the Third Closing to occur within the required timeframes shall be

obligations contained in this Agreement or any certificate or document delivered
in accordance with the terms of the Agreement, or any schedule hereto or
thereto.

                  (a) If any third party shall notify any party (the
"Indemnified Party") with respect to any matter (a "Third Party Claim") which
may give rise to a claim for indemnification against any other party (the
"Indemnifying Party") under this Article 6, then the Indemnified Party shall
promptly notify each Indemnifying Party thereof in writing; provided, however,
that no delay on the part of the Indemnified Party in notifying any Indemnifying
Party shall relieve the Indemnifying Party from any obligation hereunder unless
the Indemnifying Party is materially prejudiced thereby.

                  (b) Any Indemnifying Party will have the right to defend the
Indemnified Party against the Third Party Claim with counsel of its choice
reasonably satisfactory to the Indemnified Party so long as the Indemnifying
Party notifies the Indemnified Party in writing, within fifteen (15) days after
the Indemnified Party has given written notice of the Third Party Claim, that
the Indemnifying Party will indemnify the Indemnified Party from and against the
entirety of any Adverse Consequences that the Indemnified Party may suffer
directly resulting from, arising out of, relating to or caused by the Third
Party Claim.

                  (c) So long as the Indemnifying Party is conducting the
defense of the Third Party Claim in accordance with Section 6.5(b) above, (A)
the Indemnified Party may retain separate co-counsel at its sole cost and
expense and participate in the defense of the Third Party Claim, (B) the
Indemnified Party will not consent to the entry of any judgment or enter into
any settlement with respect to the Third Party Claim without the prior written
consent of the Indemnifying Party (not to be withheld unreasonably), and (C) the
Indemnifying Party will not consent to the entry of any judgment or enter into
any settlement with respect to the Third Party Claim without the prior written
consent of the Indemnified Party (not to be withheld unreasonably).
