neither party shall be required to settle a labor dispute against its own best
judgment); compliance with governmental laws, regulations, or orders requiring
unreasonable effort or expense; breakage or failure of machinery or apparatus;
or any other cause whether or not of the class or kind enumerated above,

of this Agreement shall prevail unless such Order Document or other written
agreement expressly modifies such terms.

     3.3 Acceptance of Orders. Except as otherwise provided for herein, only an
Order Document duly executed by NexCoal and accepted by ADA as provided in this
Article III shall constitute a firm commitment to purchase on the part of

upon receipt and shall notify ADA within ten (10) business days after receiving
an order if there is a discrepancy between the Order Documents and the shipment.
Failure to notify ADA within this period shall be deemed acceptance of the

performance of any of its obligations hereunder by Force Majeure and such party
gives written notice thereof to the other party within twenty (20) days of the
first day of such event specifying the matters constituting Force Majeure,
together with such evidence as it reasonably can give, then ADA will be excused
from the performance or punctual performance, as the case may be, as from the
date of such notice for so long as such Force Majeure continues.

                                   ARTICLE IV
                            PRICES AND PAYMENT TERMS

     4.1 Prices. The price to NexCoal for the Chemicals and Additives, Equipment
and Technical Engineering Services shall be as set forth on Schedules A and B,

                                       4
<PAGE>

an additional insured on such insurance policies. ADA shall be entitled to
reimbursement from NexCoal for all out-of-pocket cost of any insurance
specifically required to be purchased by it (in addition to its standard
coverages) under any Customer Contract. Any such additional endorsement shall be
indicated on the certificate(s) of insurance and a copy of such certificate(s)
shall be provided to NexCoal, or written notice shall be given by ADA to NexCoal
that it has been unable to add it as an additional insured, in order to allow
NexCoal to obtain appropriate coverage in its own name.

     5.2 Promoting Safe Use Practices. ADA shall use commercially reasonable
methods to inform and familiarize its employees, NexGen, customers, contractors
(including transporters) and others who may handle or use the Chemicals and
Additives of any potential hazards pertaining thereto. The foregoing shall not
limit, or be construed to limit, the obligations of ADA under Section 4.5
hereof.

this warranty, and ADA's sole liability, shall be the reperformance of the
Technical Engineering Services.

     6.4 ADA shall pass on any manufacturer's warranty on any Equipment to the

                                   ARTICLE VII
                                 INDEMNIFICATION

     Subject to the limitations set forth in Article VIII or in any other
provisions of this Agreement, each party shall defend, indemnify and hold
harmless the other party and its affiliates, customers, licensees, distributors,
directors, officers, employees and agents from and against any losses, damages,
liabilities, expenses, costs, claims, suits, demands, actions, causes of action,
proceedings, judgments, assessments, deficiencies and charges (including,
without limitation, reasonable attorney's fees and expenses (singly a "Loss" and
collectively, "Losses"), including third party claims, arising out of, on
account of or resulting from (a) the operation or conduct of such party's
business, (b) the willful misconduct or gross negligence of such party or its
directors, officers, employees or agents (other than the other party), and (c)
the breach of any representation, warranty or covenant of such party in this
Agreement.

     In addition to the indemnity provided elsewhere herein, or in the Operating
Agreement, ADA shall be solely responsible for, and shall indemnify, defend and
hold harmless NexCoal and any of its Affiliates (as such term is defined in the
Operating Agreement) from and against, any and all Loss based upon, arising out
of or in any manner related to (i) the manufacture, storage, use, handling, sale
or otherwise of the Chemicals and Additives or the Equipment, and (ii) the acts
or omissions of any of ADA's employees, agents or contractors performing or
involved with Technical Engineering Services.

                                  ARTICLE VIII
                             LIMITATION OF LIABILITY

IN NO EVENT SHALL ADA BE LIABLE TO NEXCOAL OR ANY THIRD PARTY FOR ANY SPECIAL,
CONSEQUENTIAL, INDIRECT OR INCIDENTAL DAMAGES, HOWEVER CAUSED, ON ANY THEORY OF
LIABILITY, WHETHER OR NOT ADA HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH
DAMAGES, ARISING IN ANY WAY OUT OF THIS AGREEMENT. IN NO EVENT SHALL THE
CUMULATIVE LIABILITY OF ADA EXCEED THE TOTAL AMOUNT ADA RECEIVED HEREUNDER.

The limitations of this Article VIII will apply even if ADA has been advised of
such possible damages. Some jurisdictions, states, or provinces do not allow the
exclusion or limitation of incidental or consequential damages, so the
limitation or exclusion included in this Agreement may not apply. All other
limitations under applicable law, including any statutes of limitations, shall
continue to apply. NexCoal acknowledges that ADA's pricing reflects this
allocation of risk, and the limitation of liability specified in this section
will apply regardless of whether any limited or exclusive remedy specified in
this Agreement fails of its essential purpose.

                            Chemicals, Equipment and
                 Technical Engineering Services Supply Agreement


                Chemicals and Additives and Equipment Terms List
                ------------------------------------------------

     o    Mercury control halogen additive - ADA will purchase this chemical at
          prevailing market rate (i.e., the best rate ADA can purchase it for
          commercially) and will sell it to NexCoal at 50% margin (ADA's
          standard margin). As an example, the current commercial market rate
          (as of September 30, 2006) for this chemical is approximately
          $2000/ton, so NexCoal's price would be $3000/ton, undelivered.

     o    Iron mineralizer additive - ADA's current published commercial rate
          for this chemical is $55/ton, undelivered. ADA will sell this additive
          to NexCoal at its current published commercial rate of $55/ton, plus
          delivery cost.

     o    Other chemicals or additives that may be required for coal treatment
          will be sold by ADA to NexCoal at ADA's cost, plus its standard
          commercial mark-up of 50%. In no event will ADA charge NexCoal a
          greater price than it charges unaffiliated third party purchasers.

     o    Equipment will be sold to NexCoal by ADA at ADA's cost, plus delivery,
          without mark-up.

Price changes will be provided to NexCoal in writing by ADA from time to time,
based on raw material prices charged to ADA by its suppliers. However, in no
event shall ADA impose cumulative annual price increases in any calendar year
that exceed the increase in the Consumer Price Index for All Urban Consumers,
U.S. City Average for all items (CPI-U), published by the United States Bureau
of Labor Statistics of the Department of Labor for the prior calendar year. At
NexCoal's request, ADA will supply NexCoal with copies of any invoices or
similar or related documents evidencing the raw material prices charged to ADA
by its suppliers.

     o    All Chemicals and Additives and Equipment will be sold FOB ADA or its
          designee. ADA will arrange for purchase and delivery to the location
          specified in an Order Document.

     o    Delivery and risk of loss will pass to NexCoal at ADA facility
          location (or that of its supplier). NexCoal will be responsible for
          transportation and insurance costs, which will be reimbursed to ADA,
          if not paid directly by NexCoal

     o    Delivery charges and insurance arranged for by ADA will be added to
          each order at ADA's cost, with no mark-up.

                                Orders Procedure
                                ----------------


The following procedures will apply to the submission and acceptance of Order
Documents:

1. NexCoal must submit a written Purchase Order (or similar document), signed by
an authorized NexCoal representative, specifying in detail the Chemicals and
Additives, Equipment and Technical Engineering Services requested to be supplied
by ADA. Each Purchase Order must provide specific information which shall
include at least the following, plus such other information as ADA may
reasonably request to allow it to fulfill the order:

     (i)  the Chemicals and Additives, Equipment and/or Technical Engineering
          Services requested,

     (ii) the quantities required,

     (iii) the time and place for delivery,

     (iv) the prices to be paid therefor; and

     (v)  any insurance and/or delivery arrangements requested to be provided by
          ADA.

2. Upon receipt of a Purchase Order, ADA shall review it and either (i) accept
it by signing it, returning a signed copy to NexCoal, or (ii) contact NexCoal
with suggested changes and/or issues to be resolved to satisfy ADA's concerns.

3. NexCoal and ADA shall discuss any required changes and resolve any issues
raised by ADA and/or NexCoal. NexCoal shall then resubmit the Purchase Order,
with revisions as necessary to address ADA's concerns. ADA shall then review it
and either (i) accept it by signing it, returning a signed copy to NexCoal, or
(ii) contact NexCoal with any further suggested changes and/or issues to be
resolved to satisfy ADA's concerns.

4. This process shall continue until ADA returns a signed Purchase Order to
NexCoal. Only upon ADA's written acceptance of a Purchase Order shall it become
a binding agreement upon ADA.
