Item 5.        Other Events

On November 9, 1999, the Company entered into a $45 million bank credit
facility.  The credit facility includes a credit enhancement of a tax-exempt
bond offering, which was completed on November 10, 1999, and a revolving loan
facility.  The related credit and reimbursement agreement is among the Company,
Sanwa Bank California as agents for the lenders and Keybank National Association
as the bond letter of credit issuing bank.  Other lenders include Imperial Bank,
General Bank and First Bank of California.

A total of $26.5 million of tax-exempt bonds were sold to finance the
construction of the Company's new mixed waste processing facility located in
Richland, Washington.  The bonds were sold pursuant to a loan agreement between
the Company and the Port of Benton Economic Development Corporation.  The bank
credit facility provides a letter of credit enhancement of these bonds.  The
initial term of the letter of credit is five years.  The tax-exempt bonds have
an expected maturity of 15 years.  Tax-exempt interest on the bonds is based on
a weekly floating interest rate, 3.90% as of February 16, 2000.  The bond letter
of credit fee is based on a grid that fluctuates with the changes in the net
funded debt to EBITDA ratio.  The letter of credit fee was 2.75% as of the
closing and for the first six months of the facility.

The revolving loan facility provides the Company with up to $18 million of
working capital.  The revolving facility is for a term of five years with
reductions in the maximum available to $16.5 million after 12/31/00 and $15.0
million after 12/31/01.  This loan facility bears interest based on the same
grid as the bond letter of credit, currently the prime interest rate plus .75%
(9.50%).

The credit facility is secured by all of the company's assets, including
intellectual property, that are not secured by specific equipment loans and
leases outstanding at the closing of the credit facility.  Borrowings under the
facility are subject to certain financial covenants, initially including
maintenance of a maximum net funded debt to EBITDA ratio of 3.5:1.0; a minimum
debt service ratio of 1.5 to 1.0; a minimum current ratio of 1.1 to 1.0; and a
minimum tangible net worth as defined in the agreements.  The Company was in
compliance with these covenants at the closing date.

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

                (1)  On the terms and subject to the conditions set forth
     herein, the Bond L/C Issuing Bank shall issue the Bond Letter of Credit for
     the account of the Company in support of the Bonds and the Company's
     obligations under the Loan Agreement. The Bond Letter of Credit shall: (1)

     respective sole discretion, that the termination date may be so extended,
     the Agent shall give written notice to the Company not less than 180 days

on the last Business Day of each such month in the amount set forth in an
interest billing for such Loans delivered by the Agent to the Company (which
delivery may be telephonic and later confirmed in writing). Interest accruing on
LIBOR Loans shall be payable, in arrears, on the last day of the applicable
Interest Period therefor, or in the case of LIBOR Loans with Interest Periods
ending later than three months from the date funded, at the end of each three

               (1)   Base Rate and LIBOR Options. All Loans shall either be Base
                     ---------------------------
     Rate Loans bearing interest calculated at the Base Rate plus the Base Rate
     Spread or LIBOR Loans bearing interest, during any Interest Period, at
     LIBOR for such Interest Period plus the LIBOR Spread; provided, however,
     that (i) if the Company shall fail to elect to have a Loan funded as a
     LIBOR Loan, such Loan shall be a Base Rate Loan; (ii) no Loan may be funded
     as a LIBOR Loan so long as a Potential Default or Event of Default has
     occurred and is continuing; and (iii) at the election of the Agent, upon
     the occurrence of a Potential Default or an Event of Default, all LIBOR
     Loans then outstanding shall immediately be converted to Base Rate Loans.

               (2)   Funding of Loans. Subject to the other terms and conditions
                     ----------------
     of this Agreement, the Company may elect from time to time to have Loans
     funded by giving the Agent irrevocable notice of such election no later
     than: (i) in the case of a Base Rate Loan, 10:00 a.m. (Los Angeles time) on
     the requested funding date, and (ii) in the case of a LIBOR Loan, 10:00
     a.m. (Los Angeles time) on the third Eurodollar Business Day preceding the
     proposed funding date. The principal amount of each LIBOR Loan shall be in
     the minimum amount of $1,000,000.00 and whole multiples of $100,000.00 in
     excess thereof. The Company may elect from time to time to convert Loans
     outstanding: (i) as LIBOR Loans to Base Rate Loans by giving the Agent
     irrevocable notice of such election no later than 10:00 a.m. (Los Angeles
     time) on the last day of the Interest Period for such LIBOR Loan, and (ii)
     as Base Rate Loans to LIBOR Loans by giving the Agent irrevocable notice of
     such election no later than 10:00 a.m. (Los Angeles time) on the third
     Eurodollar Business Day preceding the proposed conversion date; provided,
     that, no more than six (6) Interest Periods may be in effect at any one
     time. Any conversion of LIBOR Loans may only be made on the last day of the
     applicable Interest Period. No Base Rate Loan may be converted into a LIBOR
     Loan if an Event of Default or Potential Default has occurred and is
     continuing at the requested conversion date. All or any part of outstanding
     Loans may be converted as provided herein, provided that partial
     conversions shall be in an amount not less than the amount required
     pursuant to the second sentence of this subparagraph (2).

               (3)   Continuation of LIBOR Loans. The Company may elect from
                     ---------------------------
     time to time to have any LIBOR Loan continued as such upon the expiration
     of the Interest Period applicable thereto by giving the Agent irrevocable
     notice of such election no later than 10:00 a.m. (Los Angeles time) on the
     third Eurodollar Business Day preceding the last day of such Interest
     Period; provided, however, that no LIBOR Loan may be continued as such when
     any Event of Default or Potential Default has occurred and is continuing,
     but shall be automatically converted to a Base Rate Loan on the last day of
     the Interest Period applicable thereto. The Agent shall notify the Company
     promptly that such automatic conversion will occur. If the Company shall
     fail to give notice of its election to continue a LIBOR Loan as such as
     provided above, the Company shall be deemed to have elected to convert the
     affected LIBOR Loan to a Base Rate Loan on the last day of the applicable
     Interest Period.

               (4)  Revolving Loan Requests.
                    -----------------------

<PAGE>

                    (i)  Each request for the funding, continuation or
          conversion of a Revolving Loan shall be evidenced by the timely
          delivery by the Company to the Agent of a duly executed Loan Request
          (which delivery may be by facsimile transmission).

                    (ii) Upon receipt of a Loan Request for the funding of a new
          Revolving Loan or upon the date of any Standard L/C Drawing with
          respect to a Standard Letter of Credit which, in accordance with this
          Agreement, is to be reimbursed from the proceeds of a Revolving Loan,
          the Agent shall notify each Lender of such Lender's Percentage Share
          thereof no later than 11:00 a.m. (Los Angeles time) on the date such
          Loan Request is received by the Agent or such Standard L/C Drawing
          made (said notice by the Agent to the Lenders to be given
          telephonically and confirmed by facsimile transmission). Each Lender
          shall make its Percentage Share of the proposed Revolving Loan
          available to the Agent, in same-day funds, on the funding date at the
          Contact Office of the Agent, at such account as the Agent shall
          designate no later than 12:00 noon (Los Angeles time). The failure of
          any Lender to advance its Percentage Share of a proposed Revolving
          Loan shall not relieve any other Lender of its obligation hereunder to
          advance its Percentage Share thereof, but no Lender shall be
          responsible for the failure of any other Lender to make any such
          advance. Nothing contained herein shall in any manner or to any extent
          be deemed to constitute a waiver by the Company of any rights, powers
          and remedies which it may have against any Lender for failure of such
          Lender to fund its Percentage Share of Revolving Loans as required by
          the Loan Documents.

               (5)  Purchases by Lenders of Interests in Interim Bond Loans.
                    -------------------------------------------------------

                    (i)  Each Lender shall pay to the Bond L/C Issuing Bank a
          purchase price for each Interim Bond Loan to be purchased by such
          Lender in accordance with Paragraph 2(c) equal to such Lender's
                                    --------------
          Percentage Share of the principal amount of such Interim Bond Loan.
          Such payment shall be made on the dates described and in accordance
          with the other provisions of this Paragraph 4(b)(5).
                                            -----------------

                    (ii)  If the Agent shall receive notice from the Bond L/C
          Issuing Bank or from the Company no later than 10:00 a.m. (Los Angeles
          time) on a Business Day that Interim Bond Loans shall be made on such
          day, then the Agent shall notify each Lender of such Lender's
          Percentage Share thereof no later than 11:00 a.m. (Los Angeles time)
          on such day (said notice by the Agent to the Lenders to be given
          telephonically and confirmed by facsimile transmission), and each
          Lender shall make its Percentage Share of the Interim Bond Loans
          available to the Bond L/C Issuing Bank, in same-day funds, on such
          Business Day, at such account as the Bond L/C Issuing Bank shall
          designate no later than 12:00 noon (Los Angeles time).  If the Agent
          shall receive notice from the Bond L/C Issuing Bank or from the
          Company after 11:00 a.m. (Los Angeles time) on a Business Day that
          Interim Bond Loans shall be made on such day or as soon as possible
          thereafter, then the Agent promptly shall notify each Lender of such
          Lender's

                                       8
<PAGE>

          Percentage Share thereof, and each Lender shall make its Percentage
          Share of the proposed Interim Bond Loan available to the Bond L/C
          Issuing, Bank in same-day funds, at such account as the Bond L/C
          Issuing Bank shall designate no later than 12:00 noon (Los Angeles
          time) on the next succeeding Business Day. Promptly upon receipt of
          such funds, the Bond L/C Issuing Bank shall notify the Agent of the
          amount received from each Lender.

                    (iii)  The failure of any Lender to advance its Percentage
          Share of an Interim Bond Loan shall not relieve any other Lender of
          its obligation hereunder to advance its Percentage Share thereof, but
          no Lender shall be responsible for the failure of any other Lender to
          make any such advance. Nothing contained herein shall in any manner or
          to any extent be deemed to constitute a waiver by the Company of any
          rights, powers and remedies which it may have against any Lender for
          failure of such Lender to fund its Percentage Share of Interim Bond
          Loans as required by the Loan Documents.

               4(c)  Illegality. Notwithstanding any other provisions herein, if
                     ----------
any law, regulation, treaty or directive or any change therein or in the
interpretation or application thereof, shall make it unlawful for any Lender to
make or maintain LIBOR Loans as contemplated by this Agreement: (1) the
commitment of such Lender hereunder to make or to continue LIBOR Loans or to
convert Base Rate Loans to LIBOR Loans shall forthwith be canceled and (2) such
Lender's Percentage Share of Revolving Loans then outstanding as LIBOR Loans, if
any, shall be converted automatically to Base Rate Loans at the end of their
respective Interest Periods or within such earlier period as may be required by
law. In the event of a conversion of any such Loan prior to the end of its
applicable Interest Period the Company hereby agrees promptly to pay any Lender
affected thereby, upon demand, the amounts required pursuant to Paragraph 4(d)
                                                                --------------
below, it being agreed and understood that such conversion shall constitute a
prepayment for all purposes hereof. The provisions hereof shall survive the
termination of this Agreement and payment of the outstanding Loans and all other
amounts payable hereunder.

               4(d)  Requirements of Law; Increased Costs. In the event that any
                     ------------------------------------
applicable law, order, regulation, treaty or directive issued by any central
bank or other governmental authority, agency or instrumentality or in the
governmental or judicial interpretation or application thereof, or compliance by
any Lender with any request or directive (whether or not having the force of
law) issued by any central bank or other governmental authority, agency or
instrumentality:

                     (1)  Does or shall subject any Lender to any tax of any
     kind whatsoever with respect to this Agreement or any Loans made hereunder,
     or change the basis of taxation of payments to such Lender of principal,
     fee, interest or any other amount payable hereunder (except for change in
     the rate of tax on the overall net income of such Lender);

                     (2)  Does or shall impose, modify or hold applicable any
     reserve, capital requirement, special deposit, compulsory [revolving] loan
     or similar requirements against assets held by, or deposits or other
     liabilities in or for the account of, advances or revolving loans by, or
     other credit extended by, or any other acquisition

                                       9
<PAGE>

     of funds by, any office of such Lender which are not otherwise included in
     the determination of interest payable on the Obligations on account of
     Loans; or

                     (3)  Does or shall impose on such Lender any other
condition;

and the result of any of the foregoing is to increase the cost to such Lender of
making, renewing or maintaining any Loan or to reduce any amount receivable in
respect thereof or the rate of return on the capital of such Lender or any
corporation controlling such Lender, then, in any such case, the Company shall
promptly pay to the Agent for the account of such Lender, upon receipt of the
notice described in the next sentence, any additional amounts necessary to
compensate such Lender for such additional cost or reduced amounts receivable or
rate of return as determined by such Lender with respect to this Agreement or
Loans made hereunder.  If a Lender becomes entitled to claim any additional
amounts pursuant to this Paragraph 4(d), it shall promptly notify the Agent
                         --------------
(with a copy to the Company) of the event by reason of which it has become so
entitled.  A certificate as to any additional amounts payable pursuant to the
foregoing sentence containing the calculation thereof in reasonable detail
submitted to the Company shall be conclusive in the absence of manifest error.
The provisions hereof shall survive the termination of this Agreement and
payment of the outstanding Loans and all other amounts payable hereunder.

               4(e)  Funding.  Each Lender shall be entitled to fund all or any
                     -------
portion of its Loans in any manner it may determine in its sole discretion,
including, without limitation, in the Grand Cayman inter-bank market, the London
inter-bank market and within the United States.

               4(f)  Prepayments
                     -----------

                     (1)  The Company may prepay Loans (other than LIBOR Loans)
     hereunder in whole or in part at any time, it being acknowledged and agreed
     that LIBOR Loans may not be voluntarily prepaid prior to the last day of
     their applicable Interest Periods.

                     (2)  The Company shall pay in connection with any
     prepayment hereunder all interest accrued but unpaid on Loans to which such
     prepayment is applied, and all prepayment premiums, if any, on LIBOR Loans
     to which such prepayment is applied, concurrently with payment to the Agent
     of any principal amounts.

               4(g)  Prepayment Premium.  In addition to all other payment
                     ------------------
obligations hereunder, in the event:  (1) any  Loan which is outstanding as a
LIBOR Loan is prepaid prior to the last day of the applicable Interest Period or
(2) the Company shall fail to continue or to make a conversion to a LIBOR Loan
after the Company has given notice thereof as provided in Paragraph 4(b) above,
                                                          --------------
then the Company shall immediately pay to the Lenders holding the Loans prepaid
or not made, continued or converted, through the Agent, an additional premium
sum compensating each Lender for losses, costs and expenses incurred by such
Lender in connection with such prepayment or such failure to borrow, continue or
convert. The Company acknowledges that such losses, costs and expenses are
difficult to quantify and that, in the case of the prepayment of or failure to
continue or convert to a LIBOR Loan, the following formula

                                       10
<PAGE>

represent a fair and reasonable estimate of such losses, costs and expenses:

                                                 Days remaining in
                                                 Interest Period if
                    LIBOR Rate for               prepaid, or in the
                    Interest Period              case of failure to convert
                    when prepaid or,             or to continue the proposed
                    in the case                  Interest Period

                    notice thereof by the
                    Agent plus LIBOR Spread



For purposes of calculating the current LIBOR for the days remaining in the
Interest Period for both the increment being prepaid or not converted or
continued said current LIBOR shall be an interest rate interpolated between
LIBOR quoted for standard calender periods for subsequent months maturities in
accordance with normal conventions. A certificate as to any additional amounts
payable pursuant to the foregoing sentence containing the calculation thereof
in reasonable detail submitted by a Lender to the Company shall be conclusive
in the absence of manifest error. The provisions hereof shall survive the
termination of this Agreement and the payment of all other Obligations.

          5.  Requirements of Law; Increased Costs pertaining to the Bond Letter
              ------------------------------------------------------------------
of Credit and Standard Letters of Credit. In the event that any applicable
- ----------------------------------------
law, order, regulation, treaty or directive issued by any central bank or other
Governmental Authority, agency or instrumentality or in the governmental or
judicial interpretation or application thereof, or compliance by the Bond L/C
Issuing Bank, the Standard L/C Issuing Bank or any Lender with any request or
directive (whether or not having the force of law) issued by any central bank or
other Governmental Authority, agency or instrumentality:

                    (1)  Does or shall subject the Bond L/C Issuing Bank, the
     Standard L/C Issuing Bank or any Lender to any tax of any kind whatsoever
     with respect to this Agreement, the Bond Letter of Credit, Bond Loan
     Documents, Standard Letters of Credit, Standard Loan Documents or the
     transactions contemplated hereby or thereby, or change the basis of
     taxation of payments to the Bond L/C Issuing Bank, the Standard L/C Issuing
     Bank or such Lender of principal, fee, interest or any other amount payable
     hereunder (except for change in the rate of tax on the overall net income
     of the Bond L/C Issuing Bank, the Standard L/C Issuing Bank or such
     Lender);

                    (2)  Does or shall impose, modify or hold applicable any
     reserve, capital requirement, special deposit, compulsory or similar
     requirements against assets held by, or deposits or other liabilities in or
     for the account of, advances or revolving loans by, or other credit
     extended by, or any other acquisition of funds by, any

     office of the Bond L/C Issuing Bank, the Standard L/C Issuing Bank or such
     Lender which are not otherwise included in the determination of interest
     payable on the Bond L/C Obligations or the Standard L/C Obligations; or

                    (3)  Does or shall impose on the Bond L/C Issuing Bank, the
     Standard L/C Issuing Bank or such Lender any other condition;

and the result of any of the foregoing is to increase the cost to the Bond L/C
Issuing Bank, the Standard L/C Issuing Bank or such Lender of issuing, renewing,
maintaining, supporting or participating in the Bond Letter of Credit, any
Standard Letter of Credit or to reduce any amount receivable in respect thereof
or the rate of return on the capital of the Bond L/C Issuing Bank, the Standard
L/C Issuing Bank or such Lender or any corporation controlling the Bond L/C
Issuing Bank, the Standard L/C Issuing Bank or such Lender, then, in any such
case, the Company shall promptly pay to the Bond L/C Issuing Bank, the Standard
L/C Issuing Bank or such Lender, upon its written demand made through the Agent,
any additional amounts necessary to compensate the Bond L/C Issuing Bank, the
Standard L/C Issuing Bank or such Lender for such additional cost or reduced
amounts receivable or rate of return as determined by the Bond L/C Issuing Bank,
the Standard L/C Issuing Bank or such Lender. If the Bond L/C Issuing Bank, the
Standard L/C Issuing Bank or a Lender becomes entitled to claim any additional
amounts pursuant to this Paragraph 5, it shall promptly notify the Company
                         -----------
through the Agent of the event by reason of which it has become so entitled. A
certificate as to any additional amounts payable pursuant to the foregoing
sentence containing the calculation thereof in reasonable detail submitted by
the Bond L/C Issuing Bank, the Standard L/C Issuing Bank or the Lender to the
Company through the Agent shall be conclusive in the absence of manifest error.
The provisions hereof shall survive the termination of this Agreement and
payment of the unrepaid Bond L/C Drawings, Standard L/C Obligations and all
other Bond L/C Obligations and Standard L/C Obligations.

                    -----------------
the Loans, the Bond L/C Drawings and Standard L/C Drawings shall be evidenced by
a notation on the books and records of the Agent and each Lender. The Agent
shall deliver a monthly statement of account to the Company and each Lender
setting forth the unpaid balance of Loans outstanding hereunder. Such statement
shall (absent clerical error) be deemed conclusively correct and accepted by the
Company and the Lenders unless any of such Persons notifies the Agent to the
contrary within ten (10) Business Days following delivery of such statement.
Upon any advance, conversion or prepayment with respect to any Loan, each Lender
is hereby authorized to record the date and amount of each such advance and
conversion made by such Lender, or the date and amount of each such payment or
prepayment of principal of Loan made by such Company, the applicable Interest
Period and interest rate with respect thereto, on its books (or by any analogous
method any Lender may elect consistent with its customary practices) and any
such recordation shall constitute prima facie evidence of the accuracy of the
                                  ----- -----
information so recorded absent manifest error. The failure of the Agent or any
Lender to make any such notation shall not affect in any manner or to any extent
the Company's Obligations hereunder.

               6(b)  Nature and Place of Payments. All payments made on account
                     ----------------------------
of the Obligations shall be made by the Company to the Agent for the account of
the Bond L/C Issuing Bank, the Standard L/C Issuing Bank, the Lenders or the
Agent, as applicable, without setoff or counterclaim, in lawful money of the
United States of America in immediately available same day funds, free and clear
of and without deduction for any taxes, fees or other charges of any nature
whatsoever imposed by any taxing authority and must be received by the Agent by
10:00 a.m. (Los Angeles time) on the day of payment, it being expressly agreed
and understood that if a payment is received after 10:00 a.m. (Los Angeles time)
by the Agent, such payment will be considered to have been made by the Company
on the next succeeding Business Day and interest thereon shall be payable by the
Company at the then applicable rate during such extension. All payments on
account of the Obligations shall be made to the Agent through its Contact
Office. If any payment required to be made by the Company hereunder becomes due
and payable on a day other than a Business Day, the due date thereof shall be
extended to the next succeeding Business Day and interest thereon shall be
payable at the then applicable rate during such extension. The Agent is hereby
irrevocably authorized by the Company, upon prior notice to the Company (which
notice may be telephonic), to debit the general operating account of the
Company, if any, maintained with the Agent for the full amount of monthly and
periodic interest billings, fees and other Obligations payable hereunder;
provided, however, that the failure of the Agent to so debit such account shall
not in any manner or to any extent affect the obligation of the Company to pay
such Obligations as provided herein and in the other Loan Documents.

               6(c)  Default Interest.  Notwithstanding anything to the contrary
                     ----------------
contained herein, on any date that there shall have occurred and be continuing
an Event of Default, any and all Obligations outstanding shall bear interest at
a per annum rate equal to two percent (2%) in excess of the highest rate
applicable to Loans under this Agreement.

               6(d)  Computations. All computations of interest and fees payable
                     ------------

the actual number of days elapsed.

     submitted to the Agent for its prior written approval on a form acceptable
     to the Agent or the Construction Manager, accompanied, by a copy of the
     contract to which such change order relates.

                    (4)  Acknowledge that the Agent and the Construction Manager
     may require up to ten (10) days after receiving information and
     confirmations to respond to change orders, and the Company consents to such
     delays and agrees to cooperate diligently with the Agent in the gathering
     of the information required. In addition, the Company acknowledges and
     agrees that neither the Agent nor the Construction Manager is under any
     duty to review, advise or inform the Company of, and the Agent's or
     Construction Manager's approval or disapproval shall not constitute a
     warranty or representation about, the quality or suitability of the plans
     or any modification, amendment or supplement thereto.

                    (5)  During the construction period, permit the Agent and

     contractors to require

                                       29

     the foregoing inspection rights, except where such rights have been waived
     by the Agent in writing.

                      (6)  Acknowledge that neither the Agent nor the
     Construction Manager is under any duty to supervise or to inspect the work
     of construction, the labor performed therefor, the materials used therein
     or any books and records. The Company agrees that any inspections by the
     Agent and Construction Manager are for the sole purpose of preserving the
     Agent's rights hereunder and that the Company is not entitled to rely upon
     the same with respect to materials, workmanship, compliance with the
     approved plans or otherwise. The Company intends and agrees to conduct its
     own investigations and inspections of the construction, the labor performed
     and materials supplied to determine that the quality of the Project and all
     other requirements of the construction are being performed in a manner
     satisfactory to the Company. The Company agrees to immediately notify the
     Agent and the Construction Manager, in writing, should the same be in any
     manner unsatisfactory. A failure to inspect the construction of the
     Project, any part thereof or any books and records relating thereto, shall
     not constitute a waiver of any of the Agent's rights hereunder. Inspection
     not followed by notice of default shall not constitute a waiver of any
     default then existing; nor shall it constitute an acknowledgement that
     there has been or will be compliance with the plans approved by the Agent,
     Independent Engineer or Construction Manager or that the construction is
     free from defective materials or workmanship.

                      (7)  Promptly discharge or cause to be discharged any
     mechanics' or materialmen's liens or claims of lien filed or otherwise
     asserted against the Project or any funds due any contractor and any
     proceedings for the enforcement thereof and shall promptly discharge or
     cause to be discharged any stop notices received by the Agent, the Issuer,
     or the Trustee; provided, however, that so long as no proceedings shall
     have been commenced for the enforcement of such claims or liens, the
     Company shall have the right to contest in good faith and with reasonable
     diligence the validity of any such liens or claims. In the case of stop
     notices, the Company shall have the right to contest, in good faith and
     with reasonable diligence, the validity of any stop notice, provided that
     the Company shall immediately file with the Agent, Construction Manager and
     the Trustee a bond in the form and amount required by law in order to
     release such stop notice. Neither the Agent nor the Construction Manager
     shall have any obligation to consent to any further disbursements until all
     stop notices have been fully released, bonded or discharged.

document or conversation reasonably believed by it to be genuine and correct and
to have been signed, sent or made by the proper Person or Persons and upon
advice and statements of legal counsel (including, without limitation, counsel
to the Company), independent accountants and other experts selected by the

purposes. As to the Lenders: (1) each of the Agent, the Co-Agent, the Bond L/C
Issuing Bank and the Standard L/C Issuing Bank shall be fully justified in
failing or refusing to take any action under the Loan Documents unless it shall
first receive such advice or concurrence of the Required Lenders or all of the

Co-Agent, the Bond L/C Issuing Bank nor the Standard L/C Issuing Bank shall be
deemed to have knowledge or notice of the occurrence of any Potential Default or
Event of Default hereunder unless such Person has received notice from a Lender
or the Company referring to the Loan Documents, describing such Potential
Default or Event of Default and stating that such notice is a "notice of
default." In the event that the Agent, the Co-Agent, the Bond L/C Issuing Bank
or the Standard L/C Issuing Bank receives such a notice, such Person shall give
notice thereof to the Lenders. The Agent

                                       38

Issuing Bank or the Standard L/C Issuing Bank hereinafter taken, including any
review of the affairs of the Company, shall be deemed to constitute any
representation or warranty by the Agent, the Co-Agent, the Bond L/C Issuing
Bank, or the Standard L/C Issuing Bank to any Lender. Each Lender represents to
the Agent, the Co-Agent, the Bond L/C Issuing Bank and the Standard L/C Issuing
Bank that it has, independently and without reliance upon the Agent, the Co-
Agent, the Bond L/C Issuing Bank, the Standard L/C Issuing Bank or any other
Lender, and based on such documents and information as it has deemed
appropriate, made its own appraisal of and investigation into the business,
operations, property, financial and other condition and creditworthiness of the
Company and made its own decision to enter into this Agreement. Each Lender also
represents that it will, independently and without reliance upon the Agent, the
Co-Agent, the Bond L/C Issuing Bank, the Standard L/C Issuing Bank or any other
Lender, and based on such documents and information as it shall deem appropriate
at the time, continue to make its own credit analysis, appraisals and decisions
in taking or not taking action under this Agreement, and to make such
investigation as it deems necessary to inform itself as to the business,
operations, property, financial and other condition and creditworthiness of the
Company. Except for notices, reports and other documents expressly required to
be furnished to the Lenders by the Agent, the Co-Agent, the Bond L/C Issuing
Bank, or the Standard L/C Issuing Bank hereunder, neither the Agent, the Bond
L/C Issuing Bank or the Standard L/C Issuing Bank shall have any duty or

creditworthiness of the Company which may come into the possession of the Agent,
the Co-Agent, the Bond L/C Issuing Bank, the Standard L/C Issuing Bank or any of
their respective officers, directors, employees, agents, attorneys-in-fact or
affiliates.

                                    ---------------
indemnify each of the Agent, the Co-Agent, the Bond L/C Issuing Bank, and the
Standard L/C Issuing Bank acting in their respective capacities as such (to the
extent not reimbursed by the Company and without limiting the obligation of the
Company to do so), ratably according to the respective amounts of their
Percentage Shares, from and against any and all liabilities, obligations,
losses, damages, penalties, actions, judgments, suits, costs, expenses or
disbursements of any kind whatsoever which may at any time (including without
limitation at any time following the payment of the Bond L/C Obligations) be
imposed on, incurred by or asserted against the Agent, the Co-Agent, the Bond
L/C Issuing Bank or the Standard L/C Issuing Bank in any way relating to or
arising out of the Loan Documents or any documents contemplated by or referred
to herein or the transactions contemplated hereby or any action taken or omitted
by the Agent, the Co-Agent, the Bond L/C Issuing Bank or the Standard L/C
Issuing Bank under or in connection with any of the

foregoing; provided that no Lender shall be liable for the payment of any
portion of such liabilities, obligations, losses, damages, penalties, actions,
judgments, suits, costs, expenses or disbursements resulting from the Agent's,
the Co-Agent's, the Bond L/C Issuing Bank's, or the Standard L/C Issuing Bank's
gross negligence or willful misconduct. The agreements in this subsection shall
survive the payment of the Obligations.

                           14(h)    Individual Capacity.  Each of the Agent,
                                    -------------------
the Bond L/C Issuing Bank, the Standard L/C Issuing Bank and their respective
affiliates may make revolving loans to, accept deposits from and generally
engage in any kind of business with the Company as though the Agent were not the
Agent hereunder, the Bond L/C Issuing Bank were not the Bond L/C Issuing Bank
hereunder, and the Standard L/C Issuing Bank were not the Standard L/C Issuing
Bank hereunder. With respect to such revolving loans made or renewed by them,
each of the Agent, the Bond L/C Issuing Bank, and the Standard L/C Issuing Bank
shall have the same rights and powers under the Loan Documents as any Lender and
may exercise the same as though it were not the Agent, the Co-Agent, the Bond
L/C Issuing Bank, or the Standard L/C Issuing Bank and the terms "Lender" and
"Lenders" shall include the Agent, the Co-Agent, the Bond L/C Issuing Bank and

                                    ---------------------------
Co-Agent may resign as Agent or Co-Agent under the Loan Documents upon sixty
(60) days' notice to the Lenders and agrees that it will so resign in the event
it ceases to hold any Percentage Share of the Obligations. The Agent Co-Agent
may be removed from such capacity in the event the Lenders (other than the Agent
or Co-Agent, as the case may be) shall determine in their reasonable business
judgment that the Agent or Co-Agent has consistently failed to perform the
obligations of the Agent or Co-Agent hereunder. If the Agent or Co-Agent shall
resign or be removed as provided herein, then the Lenders (other than the Agent
or the Co-Agent, as the case may be) shall appoint from among the Lenders a
successor agent or, if such Lenders are unable to agree on the appointment of a
successor agent, the Agent or Co-Agent, as the case may be, shall appoint a
successor agent for the Lenders (which successor agent shall, in either case and
assuming that there does not exist a Potential Default or Event of Default, be
reasonably acceptable to the Company), whereupon such successor agent shall
succeed to the rights, powers and duties of the Agent or Co-Agent, and the term
"Agent" or "Co-Agent" shall mean such successor agent effective upon its
appointment, and the former Agent's or Co-Agent's rights, powers and duties as
Agent or Co-Agent shall be terminated, without any other or further act or deed
on the part of such former Agent or Co-Agent or any of the parties to this
Agreement or any of the Loan Documents or successors thereto. After any retiring
Agent's or Co-Agent's resignation hereunder as Agent or Co-Agent, the provisions
of this Paragraph 14 shall inure to its benefit as to any actions taken or
        ------------
omitted to be taken by it while it was Agent under the Loan Documents.

                           14(j)    Actions by Bond L/C Issuing Bank.  Promptly
                                    --------------------------------
upon receipt or delivery, the Bond L/C Issuing Bank agrees to deliver to the
Agent all material notices, communications and other documents received or
delivered by the Bond L/C Issuing Bank pursuant to the Indenture in its capacity
as the "Bank" as defined therein. Except in respect of the Bond Letter of Credit
or as otherwise deemed necessary by the Bond L/C Issuing Bank (and not
disadvantageous to the Agent and the Lenders), the Bond L/C Issuing Bank agrees
not to grant any consents, to give any notices or to take any other actions
under the Indenture in its

                                       40
<PAGE>

capacity as the "Bank" as defined therein without the prior consent of the
Agent. The Bond L/C Issuing Bank hereby authorizes the Agent to act on behalf of
the Bond L/C Issuing Bank in giving consents and notices on behalf of the Bond
L/C Issuing Bank under the Bond Documents and further authorizes the Trustee and
Issuer to rely on such consents and notices as if they were given by the Bond
L/C Issuing Bank.

         Subsidiary from its obligations under its Guaranty or release any
         collateral at any time held for the Obligations, (7) release all or

         the Agent from releasing any Lien on Collateral that is transferred in
         accordance with the terms of this Agreement or from reconveying any
         Lien conveyed pursuant to the United States Assignment of Claims Act)

asserted against any such Person in any way relating to or arising out of this
Agreement or any document contemplated by or referred to herein, or the
transactions contemplated hereby, or any action taken or omitted by any such
Person under or in connection with any of the foregoing, including with respect
to any investigation, litigation or proceeding (including any insolvency

or the issuance, renewal or modification of the Bond Letter of Credit or any
Standard Letter of Credit or the making of any Loan or the use of the proceeds
of any Bond L/C Drawing, any Standard Letter of Credit or Loan whether or not
any Indemnified Person is a party thereto (all the foregoing, collectively, the
"Indemnified Liabilities"); provided, however, that the Company shall have no
obligation hereunder to any Indemnified Person with respect to Indemnified
Liabilities resulting from the gross negligence or willful misconduct of such
Indemnified Person. The agreements in this Paragraph 15(l) shall survive payment

of all other Bond L/C Obligations.

                           15(m)    Marshalling; Payments Set Aside. Neither the
                                    -------------------------------
Agent nor the Lenders shall be under any obligation to marshal any assets in
favor of the Company or any other Person or against or in payment of any or all
of the Obligations. To the extent that the Company makes a payment or payments
to the Agent or the Lenders (through the Agent), or the Agent on behalf of the
Lenders enforces their Liens or exercise their rights of set-off, and such
payment or payments or the proceeds of such enforcement or set-off or any part
thereof are subsequently invalidated, declared to be fraudulent or preferential,
set aside or required (including pursuant to any settlement entered into by the
Agent in its discretion) to be repaid to a trustee, receiver or any other party
in connection with any insolvency proceeding, or otherwise, then (1) to the
extent of such recovery the obligation or part thereof originally intended to be
satisfied shall be revived and continued in full force and effect as if such
payment had not been made or such enforcement or set-off had not occurred, and
(2) each Lender severally agrees to pay to the Agent upon demand its ratable
share of the total amount so recovered from or repaid by the Agent.

Documents, if an Event of Default exists, each Lender is authorized at any time
and from time to time, without prior notice to the Company (but only with prior
written notice to and the written consent of the Agent at any time at which the
Obligations are secured by any interest in real property), any such notice being
waived by the Company to the fullest extent permitted by law, to set off and
apply any and all deposits (general or special, time or demand, provisional or
final) at any time held by, and other indebtedness at any time owing to, such
Lender to or for the credit or the account of the Company against any and all
Bond L/C Obligations owing to such Lender, now or hereafter existing,
irrespective of whether or not the Agent or such Lender shall have made demand
under this Agreement or any Loan Document and although such Obligations may be
contingent or unmatured. Each Lender agrees promptly to notify the Company and
the Agent after any such set-off and application made by such Lender; provided,
however, that the failure to give such notice shall not affect the validity of
such set-off and application.

and the other Loan Documents are made and entered into for the sole protection
and legal benefit of the Company, the Lenders, the Bond L/C Issuing Bank, the
Standard L/C Issuing Bank and the Agent, and their permitted successors and
assigns, and no other Person shall be a direct or indirect legal beneficiary of,
or have any direct or indirect cause of action or claim in connection with, this
Agreement or any of the other Loan Documents. Neither the Agent, the Bond L/C
Issuing Bank, the Standard L/C Issuing Bank nor any Lender shall have any
obligation to any Person not a party to this Agreement or other Loan Documents
other than, in the case of the Bond L/C Issuing Bank, to the Trustee or other
beneficiary under the Bond Letter of Credit or, in the case of the Standard L/C
Issuing Bank, to the beneficiary of the relevant Letter of Credit.

                           15(q)   Assignments and Participations.
                                   ------------------------------

                           (1) The Agent may and any Lender, with the consent of
         the Agent may, in the ordinary course of its business and in accordance
         with applicable law, at any time assign to one or more Eligible
         Assignees all or any part of its rights and obligations under the Loan
         Documents. Such assignment shall be in such form as may be agreed to by
         the parties thereto. The consent of the Company, which shall not be
         unreasonably withheld, shall be required prior to an assignment
         becoming effective with respect to an Eligible Assignee which is not a
         Lender or any Affiliate thereof; provided, however, that if a Potential
         Default or Event of Default has occurred and is continuing, the consent
         of the Company shall not be required. Each such assignment with respect
         to an Eligible Assignee which is not a Lender or any Affiliate thereof,
         shall (unless each of the Company and the Agent otherwise consents) be
         in an amount not less than the lesser of (i) $5,000,000 (treating an
         assignment to any fund that invests in bank loans and an assignment to
         any other fund that invests in bank loans and is managed by the same
         investment advisor of such fund or by an affiliate of such investment
         advisor as a single assignment for purposes of the minimum amount) or
         (ii) the remaining amount of the assigning Lender's Revolving Loans.

                           (2) Upon (i) delivery to the Agent of an assignment,
         together with any consents required by Paragraph 15(q)(1) and (ii)
                                                ------------------
         except in the case of an assignment by a Lender to an assignee that is
         already a Lender or an Affiliate of such assigning Lender, payment of a
         $3,000 fee to the Agent for processing such assignment (unless such fee
         is waived by the Agent), such assignment shall become effective on the
         effective date specified in such assignment. The assignment shall
         constitute a representation by the Eligible Assignee to the effect that
         none of the consideration used to make the purchase of the Revolving
         Loans under the applicable assignment agreement constitutes "plan
         assets" as defined under ERISA and that the rights and interests of the
         Eligible Assignee in and under the Loan Documents will not be "plan
         assets" under ERISA or, if composed of "plan assets" will not result in
         a "prohibited transaction" or Reportable Event. On and after the
         effective date of such assignment, such Eligible Assignee shall for all
         purposes be a Lender party to this Agreement and any other Loan
         Document executed by or on behalf of the Lenders and shall have all the
         rights and obligations of a Lender under the

                                       45
<PAGE>

         Loan Documents, to the same extent as if it were an original party
         hereto, and no further consent or action by the Company, the Lenders or
         the Agent shall be required to release the transferor Lender with
         respect to the percentage of the Revolving Loans assigned to such
         Eligible Assignee. Upon the consummation of any assignment to an
         Eligible Assignee pursuant to this Paragraph 15(q), the transferor
                                            ---------------
         Lender, the Agent and the Company shall, if the transferor Lender or
         the Eligible Assignee desires that its Revolving Loans be evidenced by
         notes, make appropriate arrangements so that new notes or, as
         appropriate, replacement notes are issued to such transferor Lender and
         new notes or, as appropriate, replacement notes, are issued to such
         Eligible Assignee, in each case in principal amounts reflecting their
         respective Revolving Loans, as adjusted pursuant to such assignment.

                  (3) Any Lender may, in the ordinary course of its business and
         in accordance with applicable law, at any time sell to one or more
         banks or other entities ("Participants") participating interests in any
         portion of the Revolving Loans of such Lender, any note held by such
         Lender, or any other interest of such Lender under the Loan Documents;
         provided that, so long as no Potential Default or Event of Default has
         occurred hereunder, any Lender selling a participation (other than to
         an Affiliate) shall give prior written notice to the Company of such
         sale. In the event of any such sale by a Lender of participating
         interests to a Participant, such Lender's obligations under the Loan
         Documents shall remain unchanged, such Lender shall remain solely
         responsible to the other parties hereto for the performance of such
         obligations, such Lender shall remain the owner of its Revolving Loans
         and the holder of any note issued to it in evidence thereof for all
         purposes under the Loan Documents, all amounts payable by the Company
         under this Agreement shall be determined as if such Lender had not sold
         such participating interests, and the Company and the Agent shall
         continue to deal solely and directly with such Lender in connection
         with such Lender's rights and obligations under the Loan Documents.
         Each Lender shall retain the sole right to approve, without the consent
         of any Participant, any amendment, modification or waiver of any
         provision of the Loan Documents other than any amendment, modification
         or waiver with respect to any Revolving Loan in which such Participant
         has an interest which forgives principal, interest, fees or any
         Obligations or reduces the interest rate or fees payable with respect
         to any such Revolving Loans, extends the Revolving Loan Maturity Date,
         postpones any date fixed for any regularly-scheduled payment of
         principal of or interest on any Loan in which such Participant has an
         interest, or any regularly-scheduled payment of fees on any such
         Revolving Loan or releases all or substantially all of the Collateral.
         except upon final payment in full of all Obligations secured thereby.
         The Company agrees that each Participant shall be deemed to have the
         rights of setoff provided in this Agreement in respect of its
         participating interest in amounts owing under the Loan Documents to the
         same extent as if the amount of its participating interest were owing
         directly to it as a Lender under the Loan Documents, provided that each
         Lender shall retain the right of setoff provided in this Agreement with
         respect to the amount of participating interests sold to each
         Participant. The Lenders agree to share with each Participant, and each
         Participant, by exercising the right of setoff provided in this
         Agreement, agrees to share with each Lender, any amount received
         pursuant to the exercise of its right of setoff, such amounts to be
         shared in accordance with this Agreement as if each Participant were a
         Lender.

                  (4) The Company authorizes each Lender to disclose to any
         Participant or Eligible Assignee or any other Person acquiring an
         interest in the Loan Documents by operation of law and any prospective
         Participant or Eligible Assignee any and all information in such
         Lender's possession concerning the creditworthiness of the Company,
         including without limitation any information contained in any reports;
         provided that each Transferee and prospective Participant or Eligible
         Assignee agrees to be bound by this Paragraph 15.

                  (5) Notwithstanding any other provision in this Agreement, any
         Lender may at any time create a security interest in, or pledge, all or
         any portion of its rights under and interest in this Agreement in favor
         of the Federal Reserve Bank in accordance with Regulation A of the FRB
         or U.S. Treasury Regulation 31 CFR ss.203.14, and such Federal Reserve
         Bank may enforce such pledge or security interest in any manner
         permitted under applicable law.

                       15(r)    Confidentiality. The Agent and each Lender
                                ---------------
agrees to hold any confidential information which it may receive from the
Company pursuant to this Agreement in confidence, except for disclosure (i) to
its Affiliates and to other Lenders and their respective Affiliates, (ii) to
legal counsel, accountants, and other professional advisors to such Lender or to
a Transferee or proposed Transferee agreeing to be bound hereby, (iii) to
regulatory officials, (iv) to any Person as required by law, regulation, or
legal process, (v) to any Person in connection with any legal proceeding to
which such Lender is a party, provided that if practicable to do so, the Company
shall be given reasonable advance notice thereof, (vi) to such Lender's direct
or indirect contractual counterparties in swap agreements or to legal counsel,
accountants and other professional advisors to such counterparties.

                       15(s)    Statutory Notice. The Agent and each Lender

is obligated by this Security Agreement to do and to exercise such rights and
powers as Debtor might exercise with respect to the Collateral.

            7(b)  The Agent may execute in its own name or in the name of Debtor

            7(c)  The Agent may file photostatic or other copies of financing

            7(d)  Debtor hereby irrevocably appoints the Agent as its attorney-
in-fact to exercise such rights and powers, including without limitation, to
collect by legal proceedings or otherwise and endorse, receive and receipt for
all dividends, interest, payments, proceeds and other sums and property now or
hereafter payable on or on account of the Collateral.

            7(e)  Enter into any extension, reorganization, deposit, merger,

     8.  Collection of Collateral Payments.
         ---------------------------------

            8(a)  Debtor shall, at its sole cost and expense, endeavor to obtain
payment, when due and payable, of all sums due or to become due with respect to
any Collateral ("Collateral Payments" or a "Collateral Payment"), including,
without limitation, the taking of such action with respect thereto as the Agent
or any Secured Party may reasonably request, or, in the absence of such request,
as Debtor may reasonably deem advisable; provided, however, that Debtor shall
not, without the prior written consent of the Agent and the Secured Parties,
grant or agree to any rebate, refund, compromise or extension with respect to
any Collateral Payment or accept any prepayment on account thereof.  Upon the
request of the Agent at the direction of all the Secured Parties, Debtor will
notify and direct any party who is or might become obligated to make any
Collateral Payment, to make payment thereof to such accounts as the Agent may
direct in writing and to execute all instruments and take all action required by
the Agent to ensure the rights of the Agent for the benefit of the Secured
Parties in any Collateral subject to the Federal Assignment of Claims Act of
1940, as amended.

                                       7
<PAGE>

            8(b)  Upon the request of the Agent, which request will be made only
following the occurrence of an Event of Default, Debtor will, forthwith upon
receipt, transmit and deliver to the Agent, in the form received, all cash,
checks, drafts and other instruments for the payment of money (properly endorsed
where required so that such items may be collected by the Agent) which may be
received by Debtor at any time as payment on account of any Collateral Payment
and if such request shall be made, until delivery to the Agent, such items will
be held in trust for the Agent and the Secured Parties and will not be
commingled by Debtor with any of its other funds or property.  Thereafter, the
Agent is hereby authorized and empowered to endorse the name of Debtor on any
check, draft or other instrument for the payment of money received by the Agent
on account of any Collateral Payment if the Agent believes such endorsement is
necessary or desirable for purposes of collection.

            8(c)  Debtor will indemnify and save harmless the Agent from and
against all reasonable liabilities and expenses on account of any adverse claim
asserted against the Agent relating to any moneys received by the Agent on
account of any Collateral Payment and such obligation of Debtor shall continue
in effect after and notwithstanding the discharge of Debtor Obligations and the
release of the security interest granted in Paragraph 2 above.

     9.  Power of Attorney.
         -----------------

            9(a)  Debtor hereby grants to the Agent for the benefit of the
Secured Parties an exclusive, irrevocable power of attorney, with full power and
authority in the place and stead of Debtor to take all such action permitted
under Paragraph 7. Debtor agrees to reimburse the Agent upon demand for any
costs and expenses, including, without limitation, attorneys' fees, the Agent
may incur while acting as Debtor's attorney-in-fact hereunder, all of which
costs and expenses are included in the Obligations secured hereby. It is further
agreed and understood between the parties hereto that such care as the Agent
gives to the safekeeping of its own property of like kind shall constitute
reasonable care of the Collateral when in the Agent's possession; provided,
however, that the Agent shall not be required to make any presentment, demand or
protest, or give any notice and need not take any action to preserve any rights
against any prior party or any other person in connection with the Obligations
or with respect to the Collateral.


            9(b)  Debtor hereby grants to the Secured Parties a present,
irrevocable, paid-up royalty-free world wide and non-exclusive license under all
Intellectual Property Collateral owned by Debtor or licensed to Debtor with the
right to sublicense (both on the date hereof and in the future) to make, have
made, reproduce, have reproduced, prepare derivative works of, perform, or
display (publicly or otherwise) or otherwise use, sell, lease or distribute any
products or processes, except Intellectual Property Collateral as to which the
Secured Parties have a perfected security interest that permits exercise of the
remedies set forth herein upon an Event of Default. The Secured Parties shall
have the right to sublicense (with the right of any sublicensee to grant further
sublicenses) or unconditionally assign such license without Debtor's

                                       8
<PAGE>

consent, limited only in the case of licenses to Debtor of intellectual property
owned by unaffiliated third parties to the extent permitted in the applicable
license. Such license may be subject to the payment of royalties by Debtor to
third parties.

     10.  Remedies.  Upon the occurrence of an Event of Default, the Agent may,
          --------
without notice to or demand on Debtor and in addition to all rights and remedies
available to the Agent and the Secured Parties with respect to the Obligations,
at law, in equity or otherwise, do any one or more of the following:

            10(a)  Foreclose or otherwise enforce the Agent's security interest
in any manner permitted by law or provided for in this Security Agreement.

            10(b)  Sell, lease or otherwise dispose of any Collateral at one or
more public or private sales at the Agent's place of business or any other place
or places, including, without limitation, any broker's board or securities
exchange, whether or not such Collateral is present at the place of sale, for
cash or credit or future delivery, on such terms and in such manner as the Agent
may determine.

            10(c)  Recover from Debtor all costs and expenses, including,
without limitation, reasonable attorneys' fees (including the allocated cost of
internal counsel), incurred or paid by the Agent or any Secured Party in
exercising any right, power or remedy provided by this Security Agreement.

            10(d)  Require Debtor to assemble the Collateral and make it
available to the Agent at a place to be designated by the Agent.

            10(e)  Enter onto property where any Collateral is located and take
possession thereof with or without judicial process.

            10(f)  Prior to the disposition of the Collateral, store, process,
repair or recondition it or otherwise prepare it for disposition in any manner
and to the extent the Agent deems appropriate and in connection with such
preparation and disposition, without charge, use any trademark, tradename,
copyright, patent or technical process used by Debtor.

Debtor shall be given five (5) Business Days' prior notice of the time and place
of any public sale or of the time after which any private sale or other intended
disposition of Collateral is to be made, which notice Debtor hereby agrees shall
be deemed reasonable notice thereof.  Upon any sale or other disposition
pursuant to this Security Agreement, the Agent shall have the right to deliver,
assign and transfer to the purchaser thereof the Collateral or portion thereof
so sold or disposed of.  Each purchaser at any such sale or other disposition
(including the Agent) shall hold the Collateral free from any claim or right of
whatever kind, including any equity or right of redemption of Debtor and Debtor
specifically waives (to the extent permitted by law) all rights of redemption,
stay or appraisal which it has or may have under any rule of law or statute now
existing or hereafter adopted.

liability to such Debtor, any Secured Party or any third party for failure to

and to exercise such rights and powers as such Debtor might exercise with
respect to the Collateral.

               7(b)  The Agent may execute in its own name or in the name of

to obtain payment, when due and payable, of all sums due or to become due with
respect to any Collateral ("Collateral Payments" or a "Collateral Payment"),
including, without limitation, the taking of such action with respect thereto as
the Agent or any Secured Party may reasonably request, or, in the absence of

that such Debtor shall not, without the prior written consent of the Agent and
the Secured Parties, grant or agree to any rebate, refund, compromise or
extension with respect to any Collateral Payment

                                       7
<PAGE>

or accept any prepayment on account thereof. Upon the request of the Agent at
the direction of all the Secured Parties, such Debtor will notify and direct any
party who is or might become obligated to make any Collateral Payment, to make
payment thereof to such accounts as the Agent may direct in writing and to
execute all instruments and take all action required by the Agent to ensure the
rights of the Agent for the benefit of the Secured Parties in any Collateral
subject to the Federal Assignment of Claims Act of 1940, as amended.

               8(b)  Upon the request of the Agent, which request will be made
only following the occurrence of an Event of Default, each Debtor will,
forthwith upon receipt, transmit and deliver to the Agent, in the form received,
all cash, checks, drafts and other instruments for the payment of money
(properly endorsed where required so that such items may be collected by the
Agent) which may be received by such Debtor at any time as payment on account of
any Collateral Payment and if such request shall be made, until delivery to the
Agent, such items will be held in trust for the Agent and the Secured Parties
and will not be commingled by such Debtor with any of its other funds or
property. Thereafter, the Agent is hereby authorized and empowered to endorse
the name of such Debtor on any check, draft or other instrument for the payment
of money received by the Agent on account of any Collateral Payment if the Agent
believes such endorsement is necessary or desirable for purposes of collection.

               8(c)  Each Debtor will indemnify and save harmless the Agent from

claim asserted against the Agent relating to any moneys received by the Agent on

the Secured Parties an exclusive, irrevocable power of attorney, with full power
and authority in the place and stead of such Debtor to take all such action
permitted under Paragraph 7. Each Debtor agrees to reimburse the Agent upon
demand for any costs and expenses, including, without limitation, attorneys'
fees, the Agent may incur while acting as such Debtor's attorney-in-fact
hereunder, all of which costs and expenses are included in the Obligations
secured hereby. It is further agreed and understood between the parties hereto
that such care as the Agent gives to the safekeeping of its own property of like
kind shall constitute reasonable care of the Collateral when in the Agent's
possession; provided, however, that the Agent shall not be required to make any
presentment, demand or protest, or give any notice and need not take any action
to preserve any rights against any prior party or any other person in connection
with the Obligations or with respect to the Collateral.

               9(b)  Each Debtor hereby grants to the Secured Parties a present,
irrevocable, paid-up royalty-free world wide and non-exclusive license under all

with the right to sublicense (both on the date hereof and in the future) to
make, have made, reproduce, have reproduced, prepare derivative works of,
perform, or display (publicly or otherwise) or otherwise use, sell, lease or
distribute any products or processes, except Intellectual Property Collateral as
to which the Secured Parties have a perfected security interest that permits
exercise of the remedies set forth herein upon an Event of Default.  The Secured
Parties shall have the right to sublicense (with the right of any sublicensee to
grant further sublicenses) or unconditionally assign such license without such
Debtor's consent, limited only in the case of licenses to such Debtor of
intellectual property owned by unaffiliated third parties to the extent
permitted in the applicable license.  Such license may be subject to the payment
of royalties by such Debtor to third parties.

     10.  Remedies.  Upon the occurrence of an Event of Default, the Agent may,

exchange, whether or not such Collateral is present at the place of sale, for
cash or credit or future delivery, on such terms and in such manner as the Agent
may determine.

               10(c) Recover from any Debtor all costs and expenses, including,
without limitation, reasonable attorneys' fees (including the allocated cost of
internal counsel), incurred or paid by the Agent or any Secured Party in
exercising any right, power or remedy provided by this Security Agreement.

               10(d) Require each Debtor to assemble the Collateral and make it

take possession thereof with or without judicial process.

               10(f) Prior to the disposition of the Collateral, store,

manner and to the extent the Agent deems appropriate and in connection with such
preparation and disposition, without charge, use any trademark, tradename,

hereby agrees shall be deemed reasonable notice thereof.  Upon any sale or other
disposition pursuant to this Security Agreement, the Agent shall have the right
to deliver, assign and transfer to the purchaser thereof the Collateral or

                              CONTINUING GUARANTY

          THIS CONTINUING GUARANTY (the "Guaranty") is made and dated as of the
1st day of November, 1999, by ATG RICHLAND CORPORATION, a Washington
corporation; ATG NUCLEAR SERVICES LLC, a Delaware limited liability company; and
ATG CATALYTICS LLC, a Delaware limited liability company (collectively, the
"Guarantors" and each a "Guarantor") for the benefit of SANWA BANK CALIFORNIA,
as agent (in such capacity, the "Agent") for the Bond L/C Issuing Bank, the
Standard L/C Issuing Bank and the Lenders under the Credit Agreement referred to
below.  [Capitalized terms used but not otherwise defined herein shall have the
meanings assigned to such terms in the Credit Agreement referred to below.]

                                   RECITALS

          A.  Pursuant to that certain Credit and Reimbursement Agreement dated
as of November 1, 1999 (as the same may be amended, extended or replaced  from
time to time, the "Credit Agreement," and with capitalized terms not otherwise
defined herein used with the meanings given such terms in the Credit Agreement)
by and among ATG Inc., a California corporation (the "Company"), the Agent for
the Bond L/C Issuing Bank, the Standard L/C Issuing Bank and the Lenders under
the Credit Agreement, the Bond L/C Issuing Bank, the Standard L/C Issuing Bank
and the Lenders from time to time party thereto, the Lenders have agreed to
extend credit to the Company on the terms and subject to the conditions set
forth in the Credit Agreement.

          B.  Pursuant to the Credit Agreement and as a condition precedent to
the obligation of the Lenders to extend credit thereunder, each Guarantor is
required to execute and deliver this Guaranty to the Agent for the benefit of
the Bond L/C Issuing Bank, the Standard L/C Issuing Bank and the Lenders
(collectively, the "Secured Parties").

          NOW, THEREFORE, in consideration of the above Recitals and for other
good and valuable consideration, the receipt and adequacy of which are hereby
acknowledged, each Guarantor hereby agrees as follows:

                                   AGREEMENT

          1.  Each Guarantor, jointly and severally, hereby irrevocably and
unconditionally guarantees the payment when due, upon maturity, acceleration or
otherwise, of the Obligations, whether heretofore, now, or hereafter made,
incurred or created, whether voluntary or involuntary and however arising,
absolute or contingent, liquidated or unliquidated, determined or undetermined,
whether or not such Obligations are from time to time reduced, or extinguished
and thereafter increased or incurred, whether the Company may be liable
individually or jointly with others, whether or not recovery upon such
Obligations may be or hereafter become barred by any statute of limitations, and
whether or not such Obligations may be or hereafter become otherwise invalid or
unenforceable[; provided, however, that each
<PAGE>

Guarantor shall be liable under this Guaranty for the maximum amount of such
liability that can be hereby incurred without rendering this Guaranty, as it
relates to such Guarantor, voidable under applicable law relating to fraudulent
obligations, fraudulent conveyance, or fraudulent transfer, and not for any
greater amount]. This is a continuing guaranty relating to any and all
Obligations including those arising under successive transactions which shall
either continue the Obligations or from time to time renew the same after such
have been satisfied.

          2.  Each Guarantor, jointly and severally, irrevocably and
unconditionally guarantees the payment of the Obligations whether or not due or
payable by the Company upon: (a) the dissolution, insolvency or business failure
of, or any assignment for benefit of creditors by, or commencement of any
bankruptcy, reorganization, arrangement, moratorium or other debtor relief
proceedings by or against, the Company or any Guarantor, or (b) the appointment
of a receiver for, or the attachment, restraint of or making or levying of any
order of court or legal process affecting, the property of the Company or any
Guarantor, and unconditionally promises to pay such Obligations to the Agent for
the benefit of the Secured Parties, or order, on demand, in lawful money of the
United States.

          3.  The liability of each Guarantor hereunder is exclusive and
independent of any security for or other guaranty of the Obligations, whether
executed by any Guarantor or by any other party, and the liability of each
Guarantor hereunder is not affected or impaired by (a) any direction of
application of payment by the Company or by any other party, or (b) any other
guaranty, undertaking or maximum liability of any Guarantor or of any other
party as to the Obligations, or (c) any payment on or in reduction of any such
other guaranty or undertaking, or (d) any revocation or release of any
obligations of any other guarantor of the Obligations, or (e) any dissolution,
termination or increase, decrease or change in personnel of any Guarantor, or
(f) any payment made to the Secured Parties or the Agent on the Obligations
which any of such Persons repay to the Company pursuant to court order in any
bankruptcy, reorganization, arrangement, moratorium or other debtor relief
proceeding, and each Guarantor waives any right to the deferral or modification
of such Guarantor's obligations hereunder by reason of any such proceeding.

          4.  (a)  The obligations of each Guarantor hereunder are independent
of the Obligations of the Company, and a separate action or actions may be
brought and prosecuted against any Guarantor whether or not action is brought
against the Company and whether or not the Company be joined in any such action
or actions.  Each Guarantor waives, to the fullest extent permitted by law, the
benefit of any statute of limitations affecting its liability hereunder or the
enforcement thereof.  Any payment by the Company or other circumstance which
operates to toll any statute of limitations as to the Company shall operate to
toll the statute of limitations as to each Guarantor.

              (b)  All payments made by any Guarantor under this Guaranty shall
be made without set-off or counterclaim and free and clear of and without
deductions for any present or future taxes, fees, withholdings or conditions of
any nature ("Taxes"). Each Guarantor shall pay any such Taxes, including Taxes
on any amounts so paid, and will promptly furnish each Lender with copies of any
tax receipts or such other evidence of payment as the Secured

                                       2
<PAGE>

Parties or the Agent may require. Each Guarantor shall not be liable for such
taxes (including income taxes or franchise taxes) as are imposed on or measured
by each Lender's net income by the jurisdiction (or any political subdivision
thereof) under the laws of which such Lender is organized or maintains a lending
office.

          5.  Each Guarantor authorizes the Secured Parties and the Agent
(whether or not after termination of this Guaranty), without notice or demand
(except as shall be required by applicable statute and cannot be waived), and
without affecting or impairing its liability hereunder, from time to time to (a)
renew, compromise, extend, increase, accelerate or otherwise change the time for
payment of, or otherwise change the terms of, the Obligations or any part
thereof, including increase or decrease of the rate of interest thereon; (b)
take and hold security for the payment of this Guaranty or the Obligations and
exchange, enforce, waive and release any such security; (c) apply such security
and direct the order or manner of sale thereof as the Secured Parties and the
Agent in their discretion may determine; and (d) release or substitute any one
or more endorsers, guarantors, the Company or other obligors.  The Secured
Parties and the Agent may without notice to or the further consent of the
Company or any Guarantor assign this Guaranty in whole or in part to any person
acquiring an interest in the Obligations.

          6.  It is not necessary for the Secured Parties or the Agent to
inquire into the capacity or power of the Company or the officers acting or
purporting to act on its behalf, and Obligations made or created in reliance
upon the professed exercise of such powers shall be guaranteed hereunder.

          7.  Each Guarantor waives any right to require the Secured Parties or
the Agent to: (a) proceed against the Company or any other party; (b) proceed
against or exhaust any security held from the Company; or (c) pursue any other
remedy in the Secured Parties' power whatsoever.  Each Guarantor waives any
personal defense based on or arising out of any personal defense of the Company
other than payment in full of the Obligations, including, without limitation,
any defense based on or arising out of the disability of the Company, or the
invalidity or unenforceability of the Obligations or any part thereof from any
cause, or the cessation from any cause of the liability of the Company other
than payment in full of the Obligations.  The Secured Parties and the Agent may,
at their election, foreclose on any security held for the Obligations by one or
more judicial or nonjudicial sales, or exercise any other right or remedy the
Secured Parties and the Agent may have against the Company, or any security,
without affecting or impairing in any way the liability of any Guarantor
hereunder except to the extent the Obligations have been paid.  Each Guarantor
waives any defense arising out of any such election, even though such election
operates to impair or extinguish any right of reimbursement or subrogation or
other right or remedy of such Guarantor against the Company or any security.
Each Guarantor hereby waives any claim or other rights which such Guarantor may
now have or may hereafter acquire against the Company or any other guarantor of
all or any of the Obligations that arise from the existence or performance of
such Guarantor's obligations under this Guaranty or any other of the Loan
Documents (as such claims and rights being referred to as the "Guarantor's
Conditional Rights"), including, without limitation, any right of subrogation,
reimbursement, exoneration, contribution, or indemnification, or any right to
participate in any claim or remedy which the Secured Parties or the Agent have
against the Company or any

                                       3
<PAGE>

collateral which the Secured Parties and the Agent now have or hereafter acquire
for the Obligations, whether or not such claim, remedy or right arises in equity
or under contract, statute or common law, by any payment made hereunder or
otherwise, including, without limitation, the right to take or receive from the
Company, directly or indirectly, in cash or other property or setoff or in any
other manner, payment or security on account of such claim or other rights. If,
notwithstanding the foregoing provisions, any amount shall be paid to any
Guarantor on account of Guarantor's Conditional Rights and either (a) such
amount is paid to such Guarantor at any time when the Obligations shall not have
been paid or performed in full, or (b) regardless of when such amount is paid to
such Guarantor any payment made by the Company to the Secured Parties or the
Agent is at any time determined to be a preferential payment, then such amount
paid to such Guarantor shall be deemed to be held in trust for the benefit of
the Secured Parties or the Agent and shall forthwith be paid to the Secured
Parties or the Agent to be credited and applied upon the Obligations, whether
matured or unmatured, in such order and manner as the Secured Parties or the
Agent shall determine. To the extent that any of the provisions of this
Paragraph shall not be enforceable, each Guarantor agrees that until such time
as the Obligations have been paid and performed in full and the period of time
has expired during which any payment made by the Company or such Guarantor to
the Secured Parties or the Agent may be determined to be a preferential payment,
Guarantor's Conditional Rights to the extent not validly waived shall be
subordinate to the Secured Parties' or the Agent's right to full payment and
performance of the Obligations and Guarantor shall not seek to enforce
Guarantor's Conditional Rights during such period. Each Guarantor waives all
presentments, demands for performance, protests and notices, including, without
limitation, notices of nonperformance, notices of protest, notices of dishonor,
notices of acceptance of this Guaranty, and notices of the existence, creation
or incurring of new or additional Obligations. Each Guarantor assumes all
responsibility for being and keeping itself informed of the Company's financial
condition and assets, and of all other circumstances bearing upon the risk of
nonpayment of the Obligations and the nature, scope and extent of the risks
which such Guarantor assumes and incurs hereunder, and agrees that neither the
Secured Parties nor the Agent shall have any duty to advise such Guarantor of
information known to any of them regarding such circumstances or risks. The
Agent hereby agrees to use reasonable efforts to give a copy to each Guarantor
of any formal written notice to the Company of the occurrence of an Event of
Default under the Credit Agreement; provided, however, that the failure of the
Agent to provide any such notice shall not in any manner or to any extent affect
the obligations of any Guarantor hereunder.

          8.  In addition to the Obligations, each Guarantor agrees to pay
reasonable attorneys' fees (including the allocated costs of internal counsel)
and all other costs and expenses incurred by the Secured Parties and the Agent
in enforcing this Guaranty in any action or proceeding arising out of, or
relating to, this Guaranty.  This Guaranty and the liability and obligations of
each Guarantor hereunder are binding upon such Guarantor and its successors and
assigns, and this Guaranty inures to the benefit of and is enforceable by the
Secured Parties and the Agent and their successors, transferees, and assigns.

          9.  Each Guarantor hereby represents and warrants to the Agent and the
Secured Parties as follows:

                                       4
<PAGE>

               (a)  Such Guarantor: (1) is duly organized, validly existing and
in good standing as a corporation or limited liability company under the laws of
the State of its incorporation or formation and is qualified to do business in
each jurisdiction where its ownership of property or conduct of business
requires such qualification and where failure to qualify would have a material
adverse effect on such Guarantor or its property and/or business or on the
ability of such Guarantor to pay or perform the Obligations, (2) has the
corporate or other power and authority and the legal right to own and operate
its property and to conduct business in the manner in which it does and proposes
so to do, and (3) is in compliance with all Requirements of Law and Contractual
Obligations, the failure to comply with which could have a material adverse
effect on the business, operations, assets or financial or other condition of
such Guarantor or such Guarantor and its consolidated Subsidiaries taken as a
whole.

               (b)  Such Guarantor has the corporate or other power and
authority and the legal right to execute, deliver and perform this Guaranty and
has taken all necessary corporate action to authorize the execution, delivery
and performance of this Guaranty. This Guaranty has been duly executed and
delivered on behalf of such Guarantor and constitutes the legal, valid and
binding obligation of such Guarantor enforceable against such Guarantor in
accordance with its terms, subject to the effect of applicable bankruptcy and
other similar laws affecting the rights of creditors generally and the effect of
equitable principles whether applied in an action at law or a suit in equity.

               (c)  The execution, delivery and performance of this Guaranty
will not violate any Requirement of Law or any Contractual Obligation of such
Guarantor or create or result in the creation of any Lien on any assets of such
Guarantor.

               (d)  No consent, approval, authorization of, or registration,
declaration or filing with any Person is required on the part of such Guarantor
in connection with the execution and delivery of this Guaranty or the
performance of or compliance with the terms, provisions and conditions hereof.

          10.  No right or power of the Secured Parties or the Agent hereunder
shall be deemed to have been waived by any act or conduct on the part of such
Persons, or by any neglect to exercise such right or power, or by any delay in
so doing; and every right or power shall continue in full force and effect until
specifically waived or released by an instrument in writing executed by the
Secured Parties and the Agent.

          11.  Each Guarantor agrees to execute any and all further documents,
instruments and agreements as the Agent from time to time reasonably requests to
evidence such Guarantor's obligations hereunder.

          12.  This Guaranty shall be deemed to be made under and shall be
governed by the laws of the State of California.

          13.  If any of the provisions of this Guaranty shall contravene or be
held invalid under the laws of any jurisdiction, this Guaranty shall be
construed as if not containing

                                       5
<PAGE>

those provisions and the rights and obligations of the parties hereto shall be
construed and enforced accordingly.

          14.  Neither this Guaranty nor any provision hereof may be amended,
modified, waived, discharged, or terminated except by an instrument in writing
duly signed by or on behalf of the Secured Parties.

          15.  The rights, powers and remedies of the Secured Parties or the
Agent hereunder are cumulative and not exclusive of any other right, power, or
remedy which Lender or the Agent would otherwise have.

          16.  All notices, requests, demands, directions, and other
communications provided for hereunder must be in writing and must be personally
delivered, sent by overnight courier or mailed to each Guarantor at the address
set forth on the signature page of this Guaranty or at any other address as may
be designated by such Guarantor in a written notice sent to the Agent in
accordance with the Credit Agreement.  Any notice, request, demand, direction,
or other communication given by mail will be deemed effective on the third
calendar day after deposited in the United States mails with first class postage
prepaid, on the next business day after deposited with a reputable overnight
courier, or when delivered if given by personal delivery.

Oakland, CA 94612

     RE:  Port of Benton Economic Development Corporation Solid Waste Revenue
          Bonds, 1999 (ATG Inc. Project)

Ladies and Gentlemen:

     This firm has acted as counsel for ATG Inc., a California corporation, and
its subsidiaries, ATG Richland Corporation, a Washington Corporation, ATG
Catalytics LLC, a Delaware limited liability company, and ATG Nuclear Services
LLC, a Delaware limited liability company (each a "Transaction Party") with
respect to issuance by the Port of Benton Economic Development Corporation ("the
"Issuer") of its Solid Waste Revenue Bonds, 1999 (ATG Inc. Project) (the
"Bonds") and the negotiation and execution of the Loan Documents, Bond Documents
and the Bond Loan Documents (collectively the "Documents") as said Documents are
defined in the Credit and Reimbursement Agreement, dated as of November 1, 1999,
by and among ATG Inc., Sanwa Bank California as Agent, KeyBank National
Association as Bond L/C Issuing Bank, First Bank of California, General Bank,
and the Lenders from time to time that are party thereto. We have examined
executed copies of the Documents.

     We have also examined other documents and certificates of representatives
of the Transaction Parties as we have deemed necessary as a basis for the
opinions expressed herein.
<PAGE>

     We have assumed the genuineness of all signatures and documents submitted
to us as originals, that all copies submitted to us conform to the originals,
the legal capacity of all natural persons. As to documents executed by entities
other than the Transaction Parties, we have assumed that each such entity had
the power to enter into and perform its obligations under such documents, and
that such documents have been duly authorized, executed and delivered by, and
are binding upon and enforceable against, such entities.

     This opinion is rendered pursuant to the provisions of Section 9 (a) (1)
(xii) of the Credit and Reimbursement Agreement.

     Based on the above comments, we are of the following opinion with respect
to the Transaction Parties:

     1.   ATG Inc. is a corporation duly incorporated, validly existing and in
good standing under the laws of the State of California. ATG Richland
Corporation is a corporation duly incorporated, validly existing and in good
standing under the laws of the State of Washington. ATG Nuclear Services LLC is
a limited liability company duly formed, validly existing and in good standing
under the laws of the State of Delaware. ATG Catalytics LLC is a limited
liability company duly formed, validly existing and in good standing under the
laws of the State of Delaware.

     2.   Each Transaction Party is duly qualified, in good standing, and
authorized to do business in each jurisdiction where the failure to qualify
would have a material adverse affect on its business.

     3.   Each Transaction Party has the requisite power and authority to
execute and deliver, and to perform and observe the provisions of, each Document
to which such Transaction Party is party and related documents thereto.
<PAGE>

     4.   The execution, delivery and performance of each Document to which each
Transaction Party is party and related documents thereto have been duly
authorized by all requisite corporate or other action of such Transaction Party
and constitute legal, valid and binding obligations of such Transaction Party,
enforceable against such Transaction Party in accordance with their respective
terms, except as such enforceability may be limited by bankruptcy, insolvency,
reorganization, moratorium and other similar laws of general applicability
relating to or affecting the enforcement of creditors' rights and subject to the
qualification that general equitable principles may limit the availability of
equitable remedies, including without limitation, the remedy of specific
performance.

     5.  Each Document and related documents thereto have been duly executed and
delivered by each Transaction Party party thereto.

     6.   To the best of our knowledge, based on due inquiry, neither the
execution, delivery, or performance of any Document or the other documents
contemplated thereby nor the consummation of the transactions contemplated
thereby will (i) conflict with, or result in a violation or breach of the terms,
conditions, or provisions of, or constitute a default under any material
agreement, indenture or other instrument provided to us by a Transaction Party
under which any Transaction Party is bound or (ii) violate or conflict with any
material judgment, decree, order, statute, rule or regulation of any court or
any public, governmental or regulatory agency or body having jurisdiction over
any Transaction Party.

     7.   Neither the execution, delivery, or performance of any Document or the
other documents contemplated thereby nor the consummation of the transactions
contemplated thereby will conflict with, or result in a violation or breach of
the terms, conditions, or provisions of, or constitute a default under the
certificate or articles of incorporation, limited liability company agreement,
operating agreement or bylaws (as applicable) of any Transaction Party.

     8.   No authorization, consent, approval, permit or license of, or filing
with, any governmental or public body or authority, any lender or lessor or any
other person or
<PAGE>

entity is required to authorize, or is required in connection with, the
execution, delivery, and performance by any Transaction Party of any Documents
or the documents contemplated thereby.

     9.   Except as set forth in Exhibit E of the Credit and Reimbursement
Agreement, there are no suits, claims or disputes pending or threatened against
or affecting any Transaction Party or any of its subsidiaries, if any, the
adverse determination of which individually or in the aggregate might have a
material adverse effect on the financial condition or operations of such
Transaction Party or impair its ability to perform its obligations under any
Document to which it is party. As to those actions described in Exhibit E of the
Credit and Reimbursement Agreement, which actions are actively contested by ATG
Inc., we are advised that the amount of claimed compensatory damages asserted
against ATG Inc. is within the limits of the comprehensive general liability
insurance policy of the party which has accepted ATG Inc.'s tender of defense
and from which ATG Inc. shall seek indemnification for any costs, damages and
liability which it may incur in connection with said actions. To the extent
damages exceed or are not covered by insurance or are not recoverable by ATG
Inc. from any other party, ATG Inc. has consulted with its respective counsel in
each such action and has determined that its potential exposure does not

                       EXHIBIT E -- MATERIAL LITIGATION


     The consolidated case listed below arises from an incident occurring in
March, 1997, wherein a piece of ordnance exploded on the premises of a scrap
metal dealer in Fontana, CA. An employee of the scrap metal dealer died and four
others claim personal injuries as a result of the explosion. In 1992, ATG Inc.
had entered into a contract with the U.S. Army to "surface clear" expended
ordnance from a firing range at Ft. Irwin, CA. It subcontracted with another
party to perform the work. Although the scrap dealer had purchased expended
ordnance and scrap metal from other military facilities, the scrap dealer
indicated the scrap metal was acquired from Ft. Irwin. The allegations assert
that the subcontractor failed to properly certify the ordnance cleared from the
Ft. Irwin firing range as free of hazardous and explosive material prior to the
sale of such ordnance to the scrap dealer. The consolidated claims include
personal injury and wrongful death actions, business-related damages by the
scrap dealer, the cost of cleaning up the accident scene, and reimbursement of
workers compensation benefits paid on behalf of the workers.

     ATG Inc. vigorously disputes the allegations and has successfully tendered
the defense of the matter to the subcontractor. It will be seeking full
indemnification from the subcontractor for any and all costs, damages and
liability it may incur in these actions. The subcontractor has advised the
company that the claims for compensatory damages are within the policy limits of
its insurance coverage applicable to these claims. While some of the claims also
seek exemplary damages against ATG Inc., the Company believes there will be no
adverse material affect to the Company or its subsidiaries as a result of the
litigation which is still in discovery.

            INSURANCE AND MITIGATING FACTORS TO ENVIRONMENTAL RISK

1.   The Company carries Nuclear Insurance for up to $5MM, $2MM, $50MM for any
     accident occurring on site in its three primary locations (Washington,
     California, and Tennessee). Coverage while material is in transport if
     $15MM. The deductible is $10,000 per incident in either case.  The risk of
     spillage is minimal because waste is primarily solid or sludge material
     which is contained in double walled, sealed metal containers that meet
     federal standards.

2.   The Company carries General Liability Policy for any effects arising from
     pollution with a limitation of $15MM per occurrence and a deductible of
     $10,000 per loss.  The Company carries an excess liability policy for $5MM
     over and above its general liability.  Buildings which house material
     handling equipment are constructed to meet federal safety standards.
     Construction requirements vary depending on material being handled. (i.e.
     LLRW or LLMW)

3.   The Company carries $4.7MM of general property insurance to cover its own
     equipment.

4.   The Company also seeks indemnification under all of its contracts from the
     generator of the waste as well as from licensed haulers.

5.   Federal law stipulates that environmental nuclear waste liability, relating
     to storing waste is the generators responsibility and not the handler.
     Thus, ATG bears no additional liability after disposal.

6.   The Company's facilities are subject to frequent and routine inspections by
     numerous regulatory agencies.  The Company has never received a fine for
     safety or license violations. The Company has on-going self-administered
     employee health, safety, training, and environmental monitoring programs in
     addition to outside inspections.

7.   Licensing and permits to operate these types of disposal sites and
     processing are comprehensive taking from 2-5 years to obtain.  There are
     very few participants in the industry given the difficulty of obtaining,
     permits, licenses, and insurance.

8.   At each operating facility, Richland, WA, Oak Ridge, TN, and Columbia, SC,
     the company is required to provide financial assurance to the state that,
     in the event the company in unable to meet its obligations, the state will
     have recourse to clean up any environmental issues at the site.  These
     financial assurances can take the form of letters of credits, bonds, or
     insurance policies.  The company is required to maintain the financial
     assurance as a condition of its ongoing permit, i.e. no assurance, no
     permit, no business.  The company words with the state regulatory agency
     that holds jurisdiction to determine the level of financial assurance that
     is required.  Ultimately, the state regulatory agency must be satisfied
     that sufficient coverage is provided.  The company currently has the
     following financial assurance coverages in place:

          Oak Ridge, TN           $4.8 million  Insurance policy (AIG)
          Richland, WA             3.0 million  Insurance policy (ECS)
          Columbia, SC              .3 million  Insurance policy (ECS)
          Richland mixed waste     1.8 million  Insurance policy (ECS)

The Richland mixed waste policy must be delivered to the state 60 days ahead of
receipt of waste.  It is expected to be finalized shortly.

                             BOND PLEDGE AGREEMENT

          This Bond Pledge Agreement ("Agreement" or "Bond Pledge Agreement")
dated as of November 1, 1999 by and among ATG INC. (the "Company"), SANWA BANK
CALIFORNIA, as Agent (the "Agent") for Lenders (the "Lenders"), including
without limitation KEYBANK NATIONAL ASSOCIATION, under that certain Credit and
Reimbursement Agreement dated as of November 1, 1999 with the Company (as
amended, modified or waived, the "Reimbursement Agreement"), and BNY Western
Trust Company (as "Trustee" under the Indenture described below and herein in
its capacity as "Custodian" under said Indenture) is made and entered into with
reference to the following:

     A.   Pursuant to that certain Trust Indenture ("Indenture") dated as of
November 1, 1999 by and between Port of Benton Economic Development Corporation
(the "Issuer") and the Trustee, the Issuer is issuing its $26,500,000 Solid
Waste Revenue Bonds, 1999 (ATG Inc. Project) (the "Bonds").

     B.   Pursuant to the Indenture, Bonds tendered for purchase at the option
of a bondholder under the Indenture and purchased with funds drawn on the Letter
of Credit (as defined therein) issued by KEYBANK NATIONAL ASSOCIATION (the
"Bank") issued in accordance with the Reimbursement Agreement, which Bonds are
not remarketed by the Remarketing Agent ("Remarketing Agent") as more
particularly described in the Indenture, become Bank Bonds (as defined in the
Indenture).

     C.   Pursuant to the Reimbursement Agreement and the other Loan Documents
(as defined therein), the Company is obligated (among other matters) to
reimburse the Bank for all funds drawn under the Letter of Credit to purchase
Bonds tendered pursuant to a Purchase Demand (as defined in the Indenture) under
the Indenture which funds are not reimbursed to the Bank immediately following
such drawing with remarketing proceeds received by the Remarketing Agent under
the Indenture.

     NOW, THEREFORE, in consideration of the foregoing and for other valuable
consideration, the receipt and sufficiency of which is hereby acknowledged, the
parties hereto agree as follows:

     1.   Defined Terms.  Unless otherwise defined herein, the terms used in
          -------------
this Agreement shall have the meaning set forth in the Indenture.

     2.   Pledge.  As collateral security for the prompt and complete payment
          ------
when due of all of the obligations arising under the Reimbursement Agreement and
to further implement and secure the Bank, the Company hereby pledges and grants
to the Agent a security interest in and to all Bank Bonds and all right, title
and interest of the Company in and to the following:

          (a)  Any amounts remaining in any fund, established under and pursuant
     to the Indenture ("Remaining Funds"), after payment in full of (i) the
                                           ------
     principal of, premium, if any, and interest on the Bonds (or provision for
     payment thereof as provided in the
<PAGE>

     Indenture) and (ii) the fees, charges and expenses of the Trustee and the
     Remarketing Agent as provided in the Indenture);

          (b)  All proceeds of the Remaining Funds;

          (c)  Any and all Bank Bonds that are not purchased in lieu of
redemption.

     3.   Release of Pledge.  The Agent agrees and acknowledges that the lien
          -----------------
of this Agreement and security interest created hereunder in any Bank Bonds from
time to time encumbered by the lien hereof shall be released effective
immediately and automatically, and without any joinder, consent or action by or
notice to the Agent, the Bank or the Company of any kind upon receipt by the
Trustee (or Remarketing Agent) of remarketing proceeds with respect to such Bank
Bonds in an amount sufficient to and which proceeds the Trustee (or Remarketing
Agent) is required to remit to the Bank to reimburse the Bank in full under the
Indenture for any drawing on the Letter of Credit to pay the purchase price for
such Bank Bonds.

     4.   No Transfer by Trustee or Transfer Agent.  The Trustee shall not
          ----------------------------------------
pledge, hypothecate, transfer or release possession of any Pledged Bond (nor
direct any re-registration of any Pledged Bond on the records of any book entry
depository system authorized under the Indenture) other than in accordance with
the Indenture and this Agreement.

     5.   Remedies.  If any Event of Default shall occur under the Reimbursement
          --------
Agreement, the Agent shall have the right to foreclose the lien of the security
interest created hereby in any manner consistent with the Uniform Commercial
Code of the State of California ("UCC") by public or private sale and following
the exercise of any such remedy have the right to demand any Bank Bonds so
acquired to be registered (free and clear of any and all claim or interest of
the Company) in the name of the Agent, a nominee of the Agent or a purchaser at
any such UCC sale.

     6.   Application of Proceeds.  The Agent shall, in the event of exercise
          -----------------------
of its rights and remedies hereunder, apply any proceeds received from the sale
of Bank Bonds first to the payment of reasonable costs and expenses incurred by
the Agent in connection with the exercise of such remedies (including reasonable
attorneys' fees and expenses); second to the reimbursement of the Bank and the
other Lenders in full for any and all amounts due to the Bank and the other
Lenders under the Reimbursement Agreement; and then to the extent of funds
remaining to the Trustee for deposit, application and/or disposition pursuant to
the Indenture.

     7.   Power of Attorney.  Subject in all events to the provisions of the
          -----------------
Bonds and the Indenture, the Company hereby irrevocably assigns to and appoints
the Agent as its true and lawful attorney-in-fact, coupled with an interest, (i)
to demand and receive proceeds from remarketing of any Bonds to the extent the
Bank or any of the Lenders has not been paid in full for all amounts as may from
time to time be due under the Reimbursement Agreement, (ii) to sign and endorse
without joinder or consent of Company any instrument or document evidencing the
Bank's right to receive such proceeds, and (iii) to do all things and acts
necessary to carry out the intent of this Agreement; provided, however, that the
Agent may not exercise any rights under such power of attorney except after the
occurrence of an Event of Default under the Reimbursement Agreement.
<PAGE>

     8.   Further Assurances.  The Company agrees that at any time and from
          ------------------
time to time upon the written request of the Agent, the Company will execute and
deliver such further documents and do such further acts and things as the Agent
may reasonably request in order to effect the purposes of this Agreement.

     9.   Severability.  Any provision of this Agreement which is prohibited or
          ------------
unenforceable in any jurisdiction shall, as to such jurisdiction, be ineffective
to the extent of such prohibition or unenforceability without invalidating the
remaining provisions hereof, and any such prohibition or unenforceability in any
jurisdiction shall not invalidate or render unenforceable such provision in any
other jurisdiction.

     10.  No Waivers; Cumulative Remedies.  The Agent shall not by any act,
          -------------------------------
delay, omission, course of dealing or otherwise be deemed to have waived any of
its rights or remedies hereunder, and no waiver or claim of waiver shall be
valid unless in writing, signed by the Agent and then only to the extent therein
set forth. A waiver by the Agent of any right or remedy hereunder on any one
occasion shall not be construed as a bar to any right or remedy which the Bank
would otherwise have on any future occasion. No failure to exercise, nor any
delay in exercising on the part of the Agent, any right, power or privilege
hereunder, shall operate as a waiver thereof, nor shall any single or partial
exercise of any right, power or privilege hereunder preclude any other or
further exercise thereof or the exercise of any other right, power or privilege.
The rights and remedies herein provided are cumulative and may be exercised
singly or concurrently, and are not exclusive of any other rights or remedies
provided at law or in equity.

     11.  Governing Law.  This Agreement shall be governed by, and be
          -------------
construed and interpreted in accordance with, the laws of the State of
California.

     12.  Successors and Assigns.  This Agreement shall be binding upon the
          ----------------------
Company and the Agent and shall inure to the benefit of and be enforceable by
the parties hereto and their respective successors and assigns; provided that
this Agreement may not be assigned by the Company without the prior written
consent of the Bank.

     13.  Attorneys' Fees.  The prevailing party in any dispute resulting in
          ---------------
arbitration, litigation or other proceedings by or among the parties shall be
entitled to its costs and expenses for such proceedings including reasonable
attorneys' fees.

     14.  Counterparts; Facsimile Transmission.  This Agreement may be executed
          ------------------------------------
in counterpart, including facsimile copies, and together shall be effective as
an original of this Agreement. This Agreement, including the signature page
hereof, shall be effective as an original.

     15.  Control.  The Company agrees and the Trustee acknowledges that the
          -------
Agent shall at all times have control (as such term is defined in Section 8106
of the California Uniform Commercial Code) of the Bank Bonds and that,
accordingly, the Bonds at all times shall be (i) if certificated, either
endorsed to or registered in the name of the Agent or its nominee or (ii) if
held by a securities intermediary, either be subject to an agreement of such
securities intermediary to
<PAGE>

comply with entitlement orders of the Agent without further consent of the
Company or be registered in the name of the Agent or its nominee as the
entitlement holder.

if any, in the Bond Fund, to pay in full all of the principal and Purchase Price
of and premium, if any, and interest on the Bonds as the same shall come due,
whether at maturity, earlier redemption, acceleration or optional or mandatory
tender pursuant to the Indenture. All payments of principal and Purchase Price

costs of issuing the Bonds in excess of the amount of Bond proceeds deposited in

assumed Weekly Interest Rate Period of 47 days (the "prepaid interest reserve").
Pursuant to the Indenture, such Loan Payment shall be deposited in the Principal
and Interest Account of the Bond Fund and used by the Trustee to reimburse the
Bank for draws on the Letter of Credit made to pay interest on the Bonds.

notice thereof to the Corporation. Not later than ten (10) days following each
Interest Payment Date, the Corporation shall make a Loan Payment to the Trustee
for deposit into the Principal and Interest Account in the amount necessary to
restore the balance in the Principal and Interest Account (after any payment
from the Principal and Interest Account to reimburse the Bank on the immediately
preceding Interest Payment Date) to an amount equal to the prepaid interest
reserve. Notwithstanding the foregoing provisions of this Section 3.03(c), the
Corporation's obligation to fund the prepaid interest reserve shall be deemed to
be satisfied to the extent that capitalized interest is transferred by the

all money delivered by the Corporation to the Trustee pursuant to this Section
3.03 is so delivered.

<PAGE>

without violating the covenants contained in this section, consolidate with or
merge into another entity, or permit one or more other entities to consolidate
with or merge into it, or sell or otherwise transfer to another entity all or
substantially all of its assets and thereafter dissolve, provided that the
surviving, resulting or transferee entity, as the case may be, (i) qualifies to
do business in the State, (ii) assumes and agrees in writing to pay and perform
all of the obligations of the Corporation hereunder, (iii) has a net worth
computed according to generally accepted accounting principles that is at least
equal to the net worth of the Corporation at such time, and (iv) furnishes to
the Trustee and the Bank an opinion of Bond Counsel to the effect that such
consolidation or merger will not cause interest on the Bonds to be included in
gross income of the Owners for federal income tax purposes, and

     (b)  Maintain its qualification to do business in the State, except as
otherwise permitted hereunder.

     Section 7.02  Assignment by Corporation.  The interest of the Corporation
     ------------  -------------------------
in this Agreement may be assigned by the Corporation subject, however, to each
of the following conditions:

     (a)  No assignment shall relieve the Corporation from primary liability for
any of its obligations hereunder, and in the event of any such assignment the
Corporation shall continue to remain primarily liable for the payments specified
in Article III and for performance and observance of the other agreements on its
part provided herein to be performed and observed by it to the same extent as
though no assignment had been granted, unless the Corporation shall have
delivered to the Issuer, the Trustee and the Bank an opinion of Bond Counsel in
form and substance reasonably satisfactory to the Issuer, the Trustee and the
Bank to the effect that such a release from such liability is not prohibited by
the Act and will not adversely affect the exclusion of interest on the Bonds
from gross income of the Owners for federal income tax purposes.

     (b)  Any assignment by the Corporation shall (unless the Corporation is
released from primary liability under this Agreement pursuant to the provisions
of paragraph (a) of this Section 7.02) retain for the Corporation such rights
and interests as will permit it to perform its obligations under this Agreement,
and any assignee of the Corporation shall assume the obligations of the
Corporation hereunder to the extent of the interest assigned; and under such
circumstances such assignee shall agree in writing with the Issuer to operate
the Project or portion thereof assigned as an "industrial development facility"
within the meaning of the Act and as "solid waste disposal facilities" within
the meaning of Section 142(a)(6) of the Code.

     (c)  The Corporation shall, within 30 days after delivery thereof, furnish
or cause to be furnished to the Issuer, the Trustee and the Bank a true and
complete copy of each such assignment together with an instrument of assumption
of obligation.

     The foregoing restrictions shall not apply to any assignment of this
Agreement in connection with any consolidation, merger or transfer of assets
permitted by Section 7.01.

     Section 7.03  Operation of Project.
     ------------  --------------------

                                      -11-
<PAGE>

     (a)  The Corporation shall use the Project only in furtherance of the
lawful corporate purposes of the Corporation and only as an "industrial
development facility" as defined in the Act and as "solid waste disposal
facilities" as contemplated by Section 142(a)(6) of the Code. Except as
disclosed in the Official Statement or any opinion or written disclosure
delivered in connection herewith or the Reimbursement Agreement, the Corporation
has complied with and shall use its best efforts to continue to comply with all
legal requirements relating to the Project and the operation, repair and
maintenance of the Project, including (i) the attainment of any rezoning or
variances, building, development and other permits and approvals, and licenses
and other entitlements for use, and (ii) securing the issuance of any
certificates of occupancy or other certificates or franchises, and will provide
the Issuer with satisfactory evidence of such compliance.

     (b)  The Corporation shall make no material alteration or change in use of
the Project without the prior written consent of the Issuer and the Bank, except
any material alteration that (i) is expressly contemplated by and subject to the
conditions specified in this Agreement, (ii) is required by law or ordinance, or
(iii) that does not constitute or result in an event of default under the
Reimbursement Agreement and does not otherwise impair the ability of the
Corporation to perform its obligations hereunder; provided, however, that in no
event shall the Corporation make any material alteration or change in use of the
Project that would change the character of the Project as "industrial
development facilities" within the meaning of the Act and as "solid waste
disposal facilities" within the meaning of Section 142(a)(6) of the Code unless
there shall have been filed with the Issuer and the Trustee both the written
consent of the Bank and the written approving opinion of Bond Counsel to the
effect that such change will not cause interest on any Bond to be included in
gross income of the Owners for federal income tax purposes.

     (c)  The Corporation agrees that it shall execute and deliver to the
Issuer, from time to time, such additional documents and shall provide such
additional information as the Issuer may reasonably require to be informed of
the Corporation's status and affairs.

     Section 7.04   Compliance with Laws.  With respect to the Property and
     ------------   ---------------------
any additions, alterations and improvements thereto, the Corporation covenants
and agrees to comply at all times with all applicable requirements of federal
and State laws and with all applicable lawful requirements of any agency, board,
or commission created under the laws of the State or of any other duly
constituted public authority; provided, however, that the Corporation shall be
deemed in compliance with this section so long as it is contesting in good faith
any such requirement by appropriate legal proceedings.

     Section 7.05   Taxes and Other Governmental Charges. The Corporation
     ------------   ------------------------------------

covenants and agrees to pay all taxes and assessments or other municipal or
governmental charges, if any, lawfully levied or assessed upon or with respect
to the Property, or upon any part thereof or upon any revenues therefrom, when
the same shall become due; provided, however, that the Corporation shall be
deemed in compliance with this section so long as it is contesting in good faith
any such tax, assessment or other governmental charge.

     Section 7.06   Notice of Default.  The Corporation covenants and agrees to
     ------------   -----------------
notify the Issuer and the Trustee immediately upon the occurrence of (a) any
event described in Section

                                      -12-
<PAGE>

8.01(a); and (b) any event described in Section 8.01(b) or 8.01(c) without
regard to any cure periods mentioned therein which, with the giving of notice or
the passage of time or both, might constitute an Event of Default hereunder, and
shall state in such notice the measures it intends to take with respect thereto,
if any.

     Section 7.07   Tax-Exempt Status of the Bonds.
     ------------   ------------------------------

     (a)  It is the parties' intention and agreement that, pursuant to Section
103 of the Code, the interest paid on the Bonds shall be excluded from gross
income of the recipients of such interest for federal income tax purposes. In
order to confirm and carry out such intention, the Corporation covenants and
agrees (1) to provide such certificates, opinions of Bond Counsel and other
evidence as may be necessary or requested by the Issuer to establish the
exemption of the Bonds under Section 103 of the Code and the absence of
arbitrage expectation under Section 148 and related sections of the Code; (2)
acting alone or with the Trustee or the Issuer, to file such information and
statements with the Internal Revenue Service as may be required to establish or
preserve such exemption or as may be required by Section 103 or related sections
of the Code; (3) to comply on behalf of the Issuer with the arbitrage rebate
requirement to the extent applicable to the Bonds, including the requirement to
calculate and pay to the United States, at the sole expense of the Corporation,
all arbitrage rebate amounts in the manner and at the times required by Section
148 of the Code; and (4) if required to prevent a loss of the exclusion from
gross income for federal income tax purposes of interest on the Bonds because of
any failure to meet arbitrage rebate requirements applicable to those Bonds
under Section 148 of the Code, to pay on behalf of the Issuer the penalty and
interest thereon as provided in Subsection 148(f)(7)(C) of the Code. The
Corporation further covenants and agrees that it will not (a) take any action,
(b) fail to take any action or (c) make any use of the Property or the proceeds
of the Bonds, which would cause the interest on the Bonds to be or become
includable in the gross income of the Owners thereof (other than substantial
users of the Property) for federal income tax purposes. Without limiting the
generality of the foregoing, the Corporation further covenants and agrees that
it will take such action or actions, including, without limitation, consenting
and agreeing to amendments to this Agreement or any of the other documents as
may be necessary, in the opinion of Bond Counsel, so that the Corporation and
all subsequent owners of the Property comply fully and continuously with the
Code, as applicable to the Bonds from time to time, and all applicable rules,
rulings, policies, procedures, regulations or other official statements
promulgated or proposed by the Department of the Treasury or the Internal
Revenue Service pertaining to exempt facility bonds issued to finance "solid
waste disposal facilities" (as defined in the Code), including, without
limitation, the Treasury Regulations.

     (b)  The Corporation reasonably expects that the Project will be used as a
solid waste disposal facility for the entire term of the Bonds, and will take
(or cause to be taken) all action necessary to ensure that the Project is used
exclusively as a "solid waste disposal facility" within the meaning of Section
142(a)(6) of the Code so long as any Bonds are Outstanding.

     (c)  The Project shall be located wholly within the boundaries of the Port
of Benton, Benton County, Washington.

                                      -13-
<PAGE>

     (d)  The Corporation shall not permit the Project to be used or the
proceeds of the Bonds to be invested in such a manner as to cause the Bonds to
be considered guaranteed (in whole or in part) by the United States (or by an
agency or instrumentality) within the meaning of Section 149(b) of the Code.

     (e)  The Corporation shall be the only principal user of the Project within
the meaning of Section 144(a)(4) of the Code, unless the Corporation provides
the Owners with an opinion of Bond Counsel satisfactory to the Owners to the
effect that the addition of one or more principal users (such users, together
with the Corporation, shall be referred to herein as "Users") shall not (i)
cause the Project to lose its status as an "industrial development facility"
under the Act or a "solid waste disposal facility" under Section 142(a)(6) of
the Code, or (ii) cause the interest on the Bonds to be included in gross income
for federal income tax purposes.

     Section 7.08   Indemnification.
     ------------   ---------------

     (a)  The Corporation covenants and agrees, at its expense, to pay and to
indemnify and hold the Issuer and the Trustee and their commissioners, officers,
agents and employees harmless of, from and against any and all claims, damages,
demands, expenses, liabilities and taxes of any character or nature whatsoever
relating to the Loan, the Bonds or the Project, including, but not limited to,
claims for loss or damage to any property or injury to or death of any person,
asserted by or on behalf of any person and arising out of, resulting from, or in
any way connected with the Property, or the conditions, occupancy, use,
possession, conduct or management of or any work done in or about the Property
or from the planning, design, construction, improvement and refinancing of the
Property, or any part thereof; or any untrue statement or alleged untrue
statement of any material fact or the omission or alleged omission to state a
material fact necessary to make the statements made in any statement,
information or material furnished by the Corporation to the Issuer or the
Remarketing Agent including, but not limited to, any information for use in any
official statement used by the Issuer or the Remarketing Agent in connection
with the sale of the Bonds, not misleading; provided that this covenant shall be
subject to the provisions of Section 7.08(c).

     (b)  The Corporation further covenants and agrees, at its expense, to pay
and to indemnify and hold the Issuer and the Trustee and their commissioners,
officers, agents and employees harmless of, from and against all costs,
reasonable counsel fees, expenses and liabilities incurred in any action or
proceeding brought by reason of any claim or demand described in Section
7.08(a). In the event that any action or proceeding is brought against the
Issuer or the Trustee or their commissioners, officers or employees by reason of
any such claim or demand, the Corporation, upon notice from the Issuer or the
Trustee, as applicable, covenants and agrees to resist and defend such action or
proceeding on behalf of the Issuer or the Trustee or their commissioners,
officers or employees; provided that this covenant shall be subject to the
provisions of Section 7.08(c).

     (c)  The Corporation shall not be obligated to indemnify the Issuer or the
Trustee or their commissioners, officers, agents or employees in the
circumstances described in Sections 7.08(a) and (b) against liability for
damages arising out of bodily injury to persons or damage to property caused by
its or their negligence or willful and malicious acts.

                                      -14-
<PAGE>

     (d)  The Corporation covenants and agrees, at its expense, to pay and to
indemnify and hold the Trustee harmless of, from and against all costs,
reasonable counsel fees, expenses and liabilities incurred without negligence or
willful misconduct by the Trustee and arising out of or in connection with its
acting as trustee and bond registrar under the Indenture.

     (e)  The provisions of this Section 7.08 are subject to the provisions of
Section 3.08(a) and shall, to the extent permitted by law, survive termination
of this Agreement.

     Section 7.09   Corporation's Performance Under Indenture. The Corporation
     ------------   -----------------------------------------
shall, for the benefit of the Owners of the Bonds, the Bank and the Trustee, do
and perform all acts and things that are to be done or performed by it, either
directly on its own behalf or on behalf of the Issuer, under the terms of the
Indenture, all of which terms are incorporated herein by this reference. Upon
request from the Trustee, the Corporation shall provide to the Trustee copies of
its most recent financial statements for distribution to Bondowners who have
requested the same.

     Section 7.10   Compliance with Secondary Disclosure Requirements of the
     ------------   --------------------------------------------------------
Securities and Exchange Commission. If the interest rate on any of the Bonds is
- ----------------------------------
converted to a Term Interest Rate Period of one year or more, the Corporation
shall, on or prior to the commencement of such Term Interest Rate Period, enter
into a binding agreement or undertaking (the "Undertaking") with the Issuer, the
Trustee (acting in a separate capacity and under a separate agreement as
dissemination agent) or another dissemination agent, the Remarketing Agent and
the Owners of those Bonds, that complies with Rule 15c2-12(b)(5)(i), promulgated
by the Securities and Exchange Commission under the Securities Exchange Act of
1934, as amended, in effect on the date of such binding agreement. Failure of
the Corporation or the dissemination agent to comply with this Section 7.10 or
the Undertaking shall not be considered an Event of Default hereunder or under
the Indenture; however the Trustee, acting as dissemination agent, may (and, at
the request of the Owners of at least a majority in aggregate principal amount
of the Bonds Outstanding, accompanied by indemnity satisfactory to it, shall) or
any Owner may, take such actions as may be necessary and appropriate, including
seeking specific performance by court order, to cause the Corporation or
dissemination agent to comply with its obligations under this Section 7.10 or
the Undertaking.

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

under any other provision of Article III or Section 7.08 of this Agreement

Corporation by the Issuer or the Trustee;

                                      -15-
<PAGE>

     (b)  Any other material failure on the part of the Corporation to perform
or observe any of the other duties, provisions or obligations required of it
pursuant to this Agreement (other than those set forth in Section 7.10), if such
failure shall have continued for a period of 30 days after written notice
thereof has been delivered to the Corporation by the Issuer or the Trustee,
unless the Issuer or the Trustee, as applicable, has determined that the
Corporation is then taking steps reasonably calculated to cure such failure and
the Trustee has received an opinion of Bond Counsel that such noncompliance will
not result in a Determination of Taxability; and/or

     (c)  The occurrence of any Event of Default under the Indenture; and/or

     (d)  Receipt of written notice from the Bank of the occurrence of an event
of default under the Reimbursement Agreement.

Default any one or more of the following steps may, with the prior written
consent of the Bank, and shall, at the written direction of the Bank (so long as
the Letter of Credit is in effect and the Bank has not failed to honor a
conforming draw thereunder), be taken, except that the Issuer shall have the
right to take steps under paragraph (a) below, if the Issuer has received an
opinion of Bond Counsel that the Event of Default will result in a Determination
of Taxability, and under paragraphs (b) and (c) below, without the consent of,
but with notice to, the Bank:

     (a)  The Issuer, by written notice to the Corporation and the Trustee, may
declare the entire principal balance of the Loan (if not then due and payable)
to be due and payable immediately, and upon any such declaration the principal
of the Loan shall become and be immediately due and payable, together with all
interest accrued thereon to the date of such acceleration, anything in this
Agreement to the contrary notwithstanding. It is understood and agreed that an
acceleration of the Bonds shall constitute an acceleration of the Loan without
further action by the Issuer or the Trustee;

     (b)  The Issuer shall be entitled by law or in equity to compel specific
performance by the Corporation of its obligations under this Agreement, it being
recognized that the beneficiaries of the Corporation's obligations hereunder

inspect, examine and make copies of the books and records and any and all

agreement contained herein, or for the enforcement of any other appropriate
legal or equitable remedy, as the Issuer may deem most effectual to protect and
enforce any of its rights or interests hereunder;

                                      -16-
<PAGE>

     (f)  The Issuer may institute and prosecute any proceeding at law or in
equity to abate, prevent or enjoin any violation or attempted violation of any
of the provisions hereof, or to recover monetary damages caused by such
violation or attempted violation.

     Section 8.03   No Remedy Exclusive.  No remedy conferred upon or reserved
     ------------   -------------------
to the Issuer or the Trustee by this Agreement is intended to be exclusive of
any other available remedy or remedies, but each and every such remedy shall be
cumulative and shall be in addition to every other remedy given under this
Agreement or now or hereafter existing at law or in equity or by statute, and
the Issuer or the Trustee shall be free to pursue, at the same time, each and
every remedy, at law or in equity, which it may have under this Agreement, or
otherwise.

     Section 8.04   No Implied Waiver.  No delay or omission to exercise any
     ------------   -----------------
right or power accruing upon any Event of Default shall impair any such right or
power or shall be construed to be a waiver thereof, but any such right and power
may be exercised from time to time and as often as may be deemed expedient. For
the Issuer or the Trustee to exercise any remedy, it shall not be necessary to
give any notice, other than such notice as may be expressly required herein.

     Section 8.05   Agreement to Pay Attorneys' Fees and Expenses.  If an
     ------------   ---------------------------------------------
Event of Default arises under any of the provisions of this Agreement and the
Issuer or the Trustee should employ attorneys or incur other expenses for the
collection of Loan Payments or other amounts due under this Agreement or the
enforcement of performance or observance of any obligation or agreement on the
part of the Corporation contained in this Agreement or any other Loan Document,
on demand therefor, the Corporation shall pay or reimburse the Issuer and/or the
Trustee for the reasonable fees of such attorneys and such other expenses so
incurred.

                         Assignment of Issuer's Rights
                         -----------------------------

     To secure the payment of the Bonds in accordance with their terms the
Issuer hereby assigns to the Trustee, for the benefit of the Bondowners, without
recourse, all of its rights, title and interest in this Agreement, except for
(a) its rights and interests described in Sections 3.06, 7.06, 7.07, 7.08(a),
(b) and (c) and 8.02 (except the right to accelerate payment of the Loan

                                      -20-
<PAGE>

pursuant to Section 8.02(a)) and 9.01 (the "Concurrent Rights"), which rights
and interests are held concurrently by both the Issuer and the Trustee, and (b)
its rights and interests described in Sections 3.07, 7.01, 7.02, 7.03 and 9.03
and the right to accelerate payment of the Loan pursuant to Section 8.02(a),
which rights and interests shall not be assigned ("Issuer Reserved Rights").
The Issuer's duties hereunder are not assigned.  By such assignment, the Trustee
shall succeed to all the rights and privileges of the Issuer hereunder to the
extent of such assignment.  ALL REFERENCES TO THE ISSUER HEREIN SHALL BE TREATED
AS REFERENCES TO THE TRUSTEE, ACTING AS ASSIGNEE AND DELEGATEE OF THE ISSUER TO
THE EXTENT THAT THE RIGHTS OF THE ISSUER HAVE BEEN ASSIGNED TO THE TRUSTEE,
EXCEPT THAT THOSE REFERENCES CONTAINED IN THE CONCURRENT RIGHTS SECTIONS SHALL
BE TREATED AS REFERRING TO BOTH THE TRUSTEE AND THE ISSUER, OR EITHER OF THEM,
AND THOSE REFERENCES CONTAINED IN THE ISSUER RESERVED RIGHTS SECTIONS SHALL BE
TREATED AS REFERRING TO THE ISSUER ONLY.

     To the extent any right hereunder is held concurrently, each of the Issuer
and the Trustee acting alone, and without the necessity of prior notice to or
consent by the other, may exercise any such Concurrent Right, but exercise of a
Concurrent Right by either the Issuer or the Trustee shall be fully and
completely binding only as among it, the Owners and the Corporation and shall
have no effect upon the other's right to act, or not to act, in connection with
any such right.  In the event of a conflict between the Issuer and the Trustee
with respect to the exercise of any Concurrent Right, the Trustee shall have the
right to direct any proceedings with respect to that right as long as any Bonds
remain outstanding.

     The Corporation hereby consents to the assignment of rights set forth in
this Article X and agrees to faithfully render the performance of all of its
duties and obligations hereunder to the Trustee except for (a) the Concurrent
Rights, which shall be rendered to both the Trustee and the Issuer, and (b) the
Issuer Reserved Rights, which shall be rendered only to the Issuer.

     When all principal of and premium, if any, and interest due on the Bonds
and all amounts owed to the Trustee under the Indenture are fully paid, the
Trustee shall release and assign to the Issuer any remaining interest it has in
this Agreement.
