“Operating Agreement”) delivered to the Obligor by the Senior Interest Holders,
the Obligor was obligated to pay to the Senior Interest Holders the Senior
Obligations.

C. The Obligor has granted a security interest in and to the Collateral to ***
and, as a condition to such grant, the Senior Interest Holders and *** entered

the Senior Interest Holders, are senior and prior to any liens or security
interests in the Collateral held by the Subordinated Lenders, and (2) the Senior
Obligations are senior and prior in right of payment to the Subordinated
Indebtedness to the extent and on the terms set forth in the Original Agreement.

D. Concurrent with the execution of this Amendment, the Obligor is issuing a
promissory note to Raser in the principal amount of $5,547,552 (the “Raser

Agreement, for and on behalf of itself and each of its successors and assigns,
desires to enter into this Amendment to (i) include Raser as a Subordinated
Lender for purposes of the Original Agreement and (ii) clarify their respective

--------------------------------------------------------------------------------

NOW THEREFORE, in consideration of the mutual covenants set out herein, the
sufficiency of which is acknowledged by all Parties, the undersigned hereby
agree as follows:

1. Section 2.6 of the Original Agreement is amended and restated in its entirety
as follows:

2.6 Acknowledgment of Liens; Agreement not to Further Subordinate. Subordinated
Lenders agree that they shall not obtain a Lien on any asset or Collateral to
secure all or any portion of the Subordinated Indebtedness unless concurrently
therewith, the parties hereby agree that all such Liens are and will be subject
to this Agreement. The Senior Interest Holders acknowledge and agree that ***
has been granted Liens by affiliates of Obligor upon all of the Collateral, and
the Senior Interest Holders and Raser hereby consent thereto. The subordination
of Liens and claims by Subordinated Lenders in favor of the Senior Interest
Holders shall not be deemed to subordinate the Liens or claims of the
Subordinated Lenders to the Liens or claims of any Person.

2. Section 2.7 of the Original Agreement is amended and restated in its entirety
as follows:

2.7 Priority of Subordinated Indebtedness Between Subordinated Lenders. Each of
the Subordinated Lenders hereby acknowledges and agrees that their respective
Subordinated Debt Documents and the Subordinated Indebtedness held by each of
them, their rights to payment and their rights in the Collateral shall be
treated pari passu as between each of them; provided, however, that, due to the
Obligor’s termination of that certain Agreement and Plan of Acquisition, dated
January 19, 2006, by and among Raser, Obligor and certain other parties (as
amended, the “Acquisition Agreement”) on June 16, 2006 (the “Termination Date”)

principal amount of the Subordinated Indebtedness held by Raser that was
outstanding on the Termination Date and that was incurred by the Obligor on or
after May 1, 2006, in the amount of $863,901.60 shall be deemed to be senior to
the Subordinated Indebtedness held by ***. Nothing in this Section 2.7 shall be
in any way interpreted to alter the rights of the Senior Interest Holders as set
forth herein.

3. The definition of “Subordinated Indebtedness” set forth on Schedule A to the
Original Agreement is amended and restated in its entirety as follows:

“Subordinated Indebtedness” means (i) all obligations and all other amounts
owing or due to the Subordinated Lenders under the Subordinated Debt Documents
and (ii) any future obligations and all other amounts owing or due to the
Subordinated Lenders as a result of monies or credit extended to the Obligor,
including principal, premium, interest, attorneys’ fees, costs, charges,
expenses, reimbursement obligations, and all other amounts payable thereunder or
in respect thereof (including, in each case, all amounts accruing on or after
the commencement of any Insolvency Proceeding relating to Obligor or any other
Person irrespective of whether a claim for all or any portion of such amounts is
allowable or allowed in any Insolvency Proceeding). Notwithstanding anything to
the contrary contained herein, the Subordinated Indebtedness may not exceed
$***, plus applicable interest, without first obtaining the Required Senior
Vote.

refinanced in whole or in part from time to time, and any other agreement
extending the maturity of, consolidating, otherwise restructuring (including
adding or deleting Subsidiaries or affiliates of Obligor or any other Persons as
parties thereto), renewing, replacing or refinancing all or any portion of the
indebtedness owed to the Subordinated Lenders.

5. The definition of “Subordinated Lenders” set forth on Schedule A to the
Original Agreement is amended and restated in its entirety as follows:
