   Two of the 50%-owned joint operations account for inventories using the
last-in, first-out (LIFO) method while the other joint operations follow FIFO.
Such LIFO inventories are carried at $54.4 million and $42.7 million at July 31,
1996 and January 31, 1996 and the excess of replacement cost over the LIFO value
at both of those dates was approximately $24.3 million. The determination of
inventory under the LIFO method can be made only at the end of the year when
ending quantities and costs are known. As of July 31, 1996, approximately $1.5
million of LIFO income, net to the Company's interest, generated by these two
joint operations has been deferred since management cannot currently estimate
their year-end inventory quantities and costs with certainty.

   The Company's investment in the joint operations and its percentage interest
in their assets and liabilities as of July 31, 1996 and January 31, 1996 are set
forth below:

   In general, the Company's unincorporated joint operations are structured so
that the participants advance and withdraw funds equally, and policy decisions
require the unanimous consent of the participants. The Company makes advances to
the joint operations, primarily for the purchase of inventory and for operating
costs, and receives periodic distributions from the joint operations, primarily
from the sales proceeds of export shipments. During the period from February 1,
1996 through July 10, 1996, the Company's advances to joint operations exceeded
distributions by $12.3 million. From July 11, 1996 through September 13, 1996,
the Company did not make advances to the joint operations on the basis of its
liquidity position and management's belief that inventory levels were excessive.
During that period a proportion of advances made to the joint operations equal
to the Company's interest was paid by one of the other joint venture partners,
and the Company's share of distributions otherwise receivable were retained by
the same partner. The Company's proportion of net advances made to the joint
ventures from July 11, 1996, through July 31, 1996, totalled $2.3 million and
have been included in the accompanying financial statements as an accounts
payable. As of September 13, 1996, distributions receivable by the Company
exceeded the Company's proportion of advances made by approximately $3.6 million
and a distribution in that amount was made to the Company.

NOTE 4: ASSET SALES

   In July, 1995, the Company sold a 65 acre tract of real estate in Houston to
an unrelated third party for $5.23 million. The consideration included $1.03
million in cash and a $4.2 million promissory note bearing interest at a bank's
prime rate. The note is payable in 66 monthly installments with the first six
payments of interest only, the next 59 payments of $61,000 of principal and
interest and a final payment of the remaining balance in January, 2001 (which
payment would approximate $2.0 million at current interest rates). The gain on
sale of $1.6 million is being accounted for using the installment method of
accounting and, accordingly, an initial $0.3 million gain on sale was recorded
during the quarter ended July 31, 1995 and $1.3 million of the gain was
deferred. The note receivable, net of the deferred gain, is included in other
assets in the accompanying balance sheet.

NOTE 5: ASSET WRITE-DOWNS AND OTHER CHARGES

   The Company reviews its long-lived assets for impairment whenever events or
changes in circumstances indicate that the carrying value of an asset may not be
recoverable. In August, 1996, management concluded that the operational and
other problems currently experienced at its new Coolidge plant resulted in the
cost of the plant exceeding the revised estimate of future undiscounted cash
flows. Based on this conclusion, the carrying value of the plant was reduced to
its estimated fair value based on revised future discounted cash flows. As a
result, the Company recognized a charge of approximately $9.3 million related to
the plant's carrying cost during the quarter ended July 31, 1996.

   The Company also recorded a charge to operations of approximately $1.4
million in the second quarter of fiscal 1997 for the accrual of costs associated
with the termination of its development of industrial waste processing and
recovery technologies conducted through its indirect wholly-owned subsidiary,
Proler Environmental Services, Inc. ("PESI"). The Company has concluded that the
capital requirements
                                        6

                                     (UNAUDITED)

for the continued development of this technology exceeds the Company's financial
capability and has deferred all discretionary expenditures on this project. The
suspension of research and development activities attributable to this operation
is expected to be completed by October 31, 1996. Research and development
expenses of PESI for the three and six months ended July 31, 1996 and 1995, were
$266,000 and $215,000, and $535,000 and $442,000, respectively. The PESI
operation had no revenues for these same periods.

NOTE 6: INCOME TAXES

   The provision for income taxes for the three and six months ended July 31,
1996 and 1995 is for the Company's share of income taxes attributable to its
corporate joint operations. For the three and six months ended July 31, 1995,
the provision for federal income taxes otherwise payable by the Company was
eliminated by the utilization of net operating loss carryforwards.

NOTE 7: BANK CREDIT FACILITIES

   In September, 1996, the Company amended its credit facilities to provide for
a $28 million revolving line of credit and a $5.7 million letter of credit
facility to maintain and renew existing letters of credit. The agreement is
collateralized by substantially all of the Company's assets, including its
rights to cash distributions from certain joint operations. As of July 31, 1996,
$25.9 million in borrowings were outstanding on the revolving line of credit and
$5.7 million of letters of credit were outstanding.

   The $28 million line of credit terminates on January 31, 1997, and the $5.7
million letter of credit facility terminates on October 31, 1997. Amounts
available under the line of credit are computed in accordance with a borrowing
base formula and are generally limited by values assigned to accounts receivable
and inventory. A commitment fee of 1/4 percent per annum is charged on the $33.7
million commitment of the bank. Borrowings under the revolving line of credit
bear interest at either the bank's prime rate plus one percent or a
Eurodollar-based rate, at the Company's option.

   Under the terms of the credit agreement, the Company must maintain, among
other things, a minimum net worth, a specified ratio of current assets to
current liabilities and specified levels of earnings before interest, taxes,
depreciation and amortization as computed in accordance with the agreements. In
addition, the Company is limited as to incurring additional indebtedness,
limited to incurring capital expenditures in excess of certain amounts, and
prohibited from paying cash dividends.

   The joint operations have recently experienced lower prices and demand from
foreign steel mills and higher levels of inventory purchases, resulting in the
accumulation of excess inventories and increased financing requirements by the
Company. As of September 13, 1996, outstanding bank borrowings totalled $21.8
million, down from a high on June 10, 1996 of $28 million.

NOTE 8: CONTINGENCIES

   Certain materials resulting from the Company's operations must be handled
consistent with federal and state environmental laws and regulations. Compliance
with such laws and regulations were an area of concern to the Company as
questions were being raised as to whether automobile shredder residue, ("ASR" or
"fluff") contains excessive concentrations of certain heavy metals,
polychlorinated biphenyls ("PCBs") and other contaminants. A 1988 United States
Environmental Protection Agency ("EPA") study released in 1990 concerning
potential contamination in ASR indicated that the potential risk depends on the
constituent make up of the fluff and the management practices at the sites where
the fluff is generated. Pending further study, the EPA recognized that shredding
operations that are well managed and conducted in an environmentally sound
manner provide valuable environmental benefits. The Company has successfully
implemented source control programs to identify and to reduce the sources of
lead and certain other heavy metals in ASR. To date, tests of ASR generated by
the Company and its joint operations indicate that levels of PCBs, lead,
cadmium, and other contaminants are generally within acceptable levels under EPA
and state procedures. The Company continues to evaluate additional methods of
further reducing contaminants in ASR. As with any business that produces
significant amounts of industrial wastes, the Company could face substantial
additional costs if past or present disposal practices would no longer be deemed
acceptable by Federal or state regulatory agencies, although it does not
currently expect this result. The Company could also be required to clean-up
sites now or formerly used in its operations.

   As reported earlier, the EPA contacted MRI Corporation, an indirect
wholly-owned subsidiary of the Company, in August 1989 regarding testing for
possible contamination at a site in Tampa, Florida previously operated by MRI.
The EPA took split soil and groundwater samples from the site for analysis. The
Company learned that in late 1990, an EPA consultant issued a report
recommending that further consideration be given to possibly ranking this site
using the EPA's hazardous ranking package. Based on that recommendation, the EPA
took additional samples at the site in 1992. The EPA visited the site in April,
1996 to observe site conditions. In June, 1996 MRI received a General Notice
Letter and Request for Information from the EPA advising MRI that it may be a
responsible party with respect to any required clean-up at the site and
requesting certain information about the site. On June 17, 1996 the EPA proposed
listing the property as a Superfund site. The EPA has informed MRI verbally that
MRI will receive a letter to participate with other potentially responsible
parties in an appropriate response. The financial effect of the EPA action on
the Company is uncertain at this time but could be material depending on the
ultimate outcome of the EPA's ongoing assessment of the property and any
remedial action required. Because the EPA's assessment of the property is
ongoing and no remedy has been proposed, the Company is unable at this time to
estimate a range of loss, if any, resulting from this matter, and no estimate
has been included for it in the financial statements.

   Hugo Neu-Proler Company ("HNP"), a 50% owned joint operation of the Company,
and the City of Los Angeles finalized a renewal of HNP's lease at its Terminal
Island location. The new lease provides for a thirty year term commencing August
30, 1994, the expiration date of the original lease. The lease has been executed
by HNP and approved by the City of Los Angeles subject to the expiration on
September 21, 1996 of the comment period on the Environmental Impact Report
issued in connection with the lease. In December, 1992, HNP signed a Memorandum
of Understanding with the Port of Los Angeles related to the lease renewal and
in fiscal 1994 and 1995 provided letters of credit totaling $9.78

million ($4.89 million each from the Company and HNP's other owner) to secure
HNP's remediation obligations under the original lease. In connection with the
lease renewal, HNP will be responsible for remediating certain environmental
conditions on the property caused by HNP, the extent and cost of which are
uncertain. Currently, HNP estimates that it will incur capital expenditures of a
minimum of $4.0 million to $5.0 million in connection with environmental control
facilities at the Terminal Island location over the next three to four years.
HNP has also accrued approximately $0.9 million to cover the costs of
anticipated remediation at this site.

   On April 17, 1996, a Los Angeles Grand Jury subpoena was issued by the
Antitrust Division of the United States Department of Justice ("DOJ") requiring
the production of certain documents and information principally concerning the
purchase and pricing of scrap metal by HNP and others in the Southern California
market. HNP is cooperating with the DOJ, and HNP and its joint venture partners
have responded to the subpoena. One HNP employee has testified before the grand
jury and the Company expects that others may be called. The ongoing
investigation appears to be in its preliminary stage.

   The Company is engaged in ongoing proceedings and communications with
regulatory authorities concerning environmental matters, and ongoing litigation
regarding non-environmental matters. An adverse outcome in these legal
proceedings, or any significant additional expenditures that may be required in
order for the Company or its joint operations to operate in accordance with
environmental laws and regulations, or to clean up sites now or formerly used by
them, could affect the Company's financial position.

NOTE 9: PER SHARE INFORMATION

     Per share calculations are based on the average number of common shares
outstanding during the period. The per share calculations do not include the
common equivalent shares attributable to the assumed exercise of outstanding
stock options since the effect was not significant for the periods presented.

NOTE 10:    SUBSEQUENT EVENT

     On September 15, 1996, the Company and Schnitzer Steel Industries, Inc.
entered into a definitive agreement for the acquisition of the Company by
Schnitzer through a cash tender offer and cash merger. See "Management's

FORWARD LOOKING STATEMENTS

   The statements contained in this report, in addition to historical
information, are forward looking statements based on the Company's current
expectations, and actual results may vary materially. The Company's business and
financial results are subject to various risks and uncertainties, including the
cyclical nature of the scrap processing business, the fact that the Company
exercises limited control over its joint operations, competitive factors such as
the availability and cost of raw scrap for inventory, fluctuations in sales
prices and demand for the products of the Company and the joint operations, the
ability to reduce excess inventories at the joint operations, the Company's
ability to correct operational problems at its Coolidge facility as projected,
the resolution of environmental issues including the MRI Tampa site and the
other risks and uncertainties discussed herein and in the Company's Annual
Report on Form 10-K. These forward looking statements are provided as a
framework for the Company's discussion of its business and management's analysis
of the Company's financial condition and results of operations. The Company does
not intend to provide updated information other than in the context of its
Quarterly Reports on Form 10-Q.

GENERAL

   The Company is primarily engaged, through its subsidiaries and its joint
operations, in buying, processing, recycling and selling ferrous and other scrap
metals. While the Company sells products from its consolidated operations
primarily to domestic markets, the joint operations primarily export scrap to
foreign markets. The Company's and its joint operations' current business is
characterized by cyclical fluctuations in profitability depending upon the
availability and price of raw scrap and the demand and prices for processed
scrap by the domestic and foreign iron and steel industries and the non-ferrous
metals industries.

   In general, the Company's unincorporated joint operations are structured so
that the participants advance and withdraw funds equally, and policy decisions
require the unanimous consent of the participants. The Company makes advances to
the joint operations, primarily for the purchase of inventory and for operating
costs, and receives periodic distributions from the joint operations, primarily
from the sales proceeds of export shipments. During the six months ended July
31, 1996, the Company's advances to joint operations exceeded distributions by
$12.3 million.

   During the past four years the Company has sold its domestic scrap
operations, certain joint venture operations, real estate holdings and other
non-operating assets. With the divestitures of the domestic scrap operations,
the Company's principal scrap processing business is conducted through its joint
operations, with the Company's remaining revenues derived from the three plants
owned by Proler Recycling, Inc. ("Proler Recycling"), a wholly-owned indirect
subsidiary of the Company.

                     CONDITION AND RESULTS OF OPERATIONS (CONT.)

   As reported earlier, the Company retained two investment firms to assist in
evaluating a broad range of strategic alternatives including sales, public or
private offerings of debt or equity securities, mergers, spin-offs, joint
ventures and acquisitions. On September 15, 1996 the Company and Schnitzer Steel
Industries, Inc. ("Schnitzer") entered into a definitive agreement for the
acquisition of Proler by Schnitzer through a cash tender offer and cash merger.
The agreement calls for Schnitzer, through a subsidiary, to commence a cash
tender offer for all of the outstanding shares of the Company within five days
of the agreement at a cash price of $7.50 per share. Upon completion of the
tender offer, the Company will become a wholly owned subsidiary of Schnitzer
through a cash merger at the same price per share. The tender offer will be
conditioned on at least a majority of the Company's outstanding shares, on a
fully diluted basis, being validly tendered and not withdrawn prior to
expiration of the offer. The expiration date of the offer will be twenty
business days following the commencement of the offer, unless the offer is
extended. The tender offer and merger are subject to expiration or termination
of the applicable waiting period under the Hart-Scott-Rodino Antitrust
Improvements Act of 1976 and other customary conditions. The Company filed a
Current Report on Form 8-K with respect to this transaction on September 16,
1996.

LIQUIDITY, FINANCING AND CAPITAL RESOURCES

   The Company's liquidity position continues to be its principal concern. The
joint ventures have continued to experience lower sales, thereby causing a
continued build up of inventory. The result has been increasing capital
requirements at the joint ventures that have strained the Company's financial
resources.

   The Company currently meets its working capital requirements from
distributions from the joint operations and borrowings under the credit facility
described below. Based on the terms of the Company's credit agreement, the $25.9
million of bank debt outstanding as of July 31, 1996 is classified as a current
liability in the Company's financial statements. As of July 31, 1996, the
Company had negative working capital of $27.5 million, as compared to $3.5
million of positive working capital reported as of January 31, 1996. Between the
same periods, the Company's share of combined working capital in the joint
ventures increased by $14.1 million, from $25.9 million to $40.0 million.

   As noted above, the Company makes advances to the joint operations and
receives periodic distributions, primarily from the sales proceeds of export
shipments. The joint operations also purchase inventory to maintain sources of
supply, even in periods of lower demand and lower sales prices. Given these
factors and the cyclical nature of the scrap markets, the Company's liquidity
can be adversely affected if lower sales, coupled with continued inventory
purchases, result in accumulation of excess inventories at the joint operations.
During the period from October, 1995 through December, 1995 and again in March,
1996 and continuing to date, the joint ventures have experienced lower prices
and demand from foreign steel mills and higher levels of inventory purchases,
resulting in the accumulation of excess inventories and increased financing
requirements. Currently, approximately 38% of these inventories are subject to
outstanding sales orders. During the period from July 11, 1996 through September
13, 1996, the Company did not make advances to the joint operations on the basis
of its liquidity position and management's belief that inventory levels were
excessive. During that period a proportion of advances made to the joint
operations equal to the Company's interest was paid by one of

the other joint venture partners, and the Company's share of distributions
otherwise receivable was retained by the same partner. See Note 3 to the
financial statements.

   The Company is financing its share of increased inventory purchases primarily
through increased borrowings under its bank credit facilities. The level of debt
is reduced as the proceeds of export sales are received. Due to the volume of
sales activity and inventory levels, the Company's bank debt has fluctuated in
recent months and the Company expects that its outstanding borrowings will
continue to fluctuate as current joint venture export sales orders are completed
and new sales are made and collected. As of July 31, 1996, borrowings of $25.9
million were outstanding under the revolving line of credit and $5.7 million of
letters of credit were outstanding under the letter of credit facility,
including $4.89 million issued in connection with a lease at a joint operation's
Los Angeles facility. In February, 1996, the Company paid the revolving line of
credit down to $0.7 million from the $9.7 million outstanding at January 31,
1996, primarily from distributions of sales proceeds of export shipments.
Beginning in March, 1996 and continuing to date, the Company has made
significant advances to the joint operations, primarily for inventory purchases,
and has funded operating losses from the consolidated operations. As of
September 13, 1996, outstanding borrowings on the revolving line of credit
totalled $21.8 million, down from a high on June 10, 1996 of $28 million, the
current commitment level of the revolver.

   As more fully described in Note 7 to the financial statements, the Company's
credit agreement with the bank, as amended, provides for a $28 million revolving
line of credit and a $5.7 million letter of credit facility. The $28 million
line of credit terminates on January 31, 1997, and the $5.7 million letter of
credit facility terminates on October 31, 1997. The agreements are
collateralized by substantially all of the Company's assets, including its
rights to distributions from certain joint operations. The revolving line of
credit is subject to a borrowing base of eligible receivables and inventory.
Management believes that the amounts available under its credit facilities,
together with distributions from the joint operations, should be sufficient to
meet its current working capital and short-term inventory financing
requirements, provided that inventories at the joint operations can be reduced
by additional sales and/or reduced levels of inventory purchases. However, those
requirements could increase if inventory accumulations at the joint ventures
continue. The Company's ability to borrow against assets of the joint operations
may be limited by the Company's inability to grant a direct security interest in
those assets to the bank and by certain limitations on the Company's ability to
pledge its interests in the joint operations.

   Contributing to the Company's liquidity problems are continued losses at
Proler Recycling's new plant in Coolidge, Arizona. The Company has completed a
reassessment of these operations and concluded that the plant could become
marginally profitable if certain continuing operational and other problems can
be resolved. However, based on current projections it is not anticipated that
the plant will reach profitability status until January, 1997.

   The Company has also determined that the cost of continued development of
gasification technology by Proler Environmental Services, Inc. ("PESI") is not
within the Company's means and has deferred all discretionary expenditures on
this project. The Company is currently seeking investors, partners and/or
acquirers for the gasification project.

   The Company is engaged in ongoing proceedings and communications with
regulatory authorities concerning environmental matters, and ongoing litigation
regarding non-environmental matters. An adverse outcome in these legal
proceedings, or any significant additional expenditures that may be required in
order for the Company or its joint operations to operate in accordance with
environmental laws and regulations, or to clean up sites now or formerly used by
them, could affect the Company's financial position. See Note 8 to the financial
statements.

      Consolidated net sales and cost of sales increased 21% and 39%,
respectively, during the quarter ended July 31, 1996 as compared to the prior
year's second quarter. Sales and cost of sales for the six months ended July 31,
1996 also had significant increases as compared to the prior period. Such
increases are primarily from the new copper recovery and specialty chemical
operations. Cost of sales exceeded the sales from these activities primarily due
to continuing operational problems. Losses attributable to these operations were
approximately $1.1 million and $1.7 million for the three and six month periods
ending July 31, 1996. Precipitation iron sales volumes declined 7% and 9% for
the three and six month periods as compared to the prior year periods; however,
gross margins increased approximately 11% and 14% for the three and six month
periods as compared to the prior year periods due mainly to lower unit
production costs resulting from the consolidation of those activities into one
location.

      Joint operations results decreased from net earnings of $2.3 million and
$4.1 million in the second quarter and first half of fiscal 1996, respectively,
to losses of $0.1 million and $0.3 million for the same periods in fiscal 1997.
As reported earlier, the Company completed the sales of the joint venture
interests in HPI and HPNJ in October, 1995. The Company's share of earnings
related to the sold joint ventures were not significant in fiscal 1996.
Excluding the results from the sold joint venture interests, the following table
highlights the more significant per ton operating information for the joint
operations.

      Gross profit margins declined 56% for the quarter ending July 31, 1996,
compared to the same period in 1995. The decline is primarily attributable to a
1% decrease in total sales volumes, combined with a 7% decrease in the overall
average sales price. The decrease in overall sales price is a result of a 7%
decline in the average ferrous sales price in the second quarter partially
offset by a 5% increase in the average nonferrous sales price. Gross profit
margins for the six month period ending July 31, 1996 as compared to the prior
year period were similarly lower due to reduced non-ferrous sales volumes and
lower ferrous sales prices, partially offset by increased ferrous sales volumes.

      General and administrative expenses increased 26% and 28% for the three
and six months periods ended July 31, 1996 compared to the same periods in 1995
primarily due to higher personnel and marketing expenses attributable to the
Company's gasification project and the copper recovery unit, plus higher banking
charges.

      Research and development expenses for the three and six months ended July
31, 1996 increased 13% and 16%, respectively, compared to the same periods in
1995 due mainly to accelerated research activities at PESI. The focus of PESI
during fiscal 1997 had been directed towards the conceptual demonstration of
gasification and vitrification of Proler's Syngas Process. In July, 1996, the
Company decided to suspend further development and is proceeding to wind down
these operations. See Note 5 to the financial statements.

      As discussed more fully in Note 5 to the financial statements, the Company
recorded asset write-downs and other charges of $10.7 million in the second
quarter of fiscal 1997.

      Interest income increased for the three and six months ended July 31, 1996
compared to the same periods of 1995 due to income from a note receivable from a
property sale consummated in July, 1995, partially offset by lower investable
cash balances. Interest expense increased for the three and six months ended
July 31, 1996 compared to the same periods of fiscal 1996 due to an increase in
outstanding bank borrowings.

      Other expense, net (which includes real estate costs of $202,000 and
$418,000 for the three and six months ended July 31, 1996, respectively, and
costs of $198,000 and $366,000 for the comparable 1995 periods) decreased 84%
for the three months ended July 31, 1996 and increased 30% for the six months
ended July 31, 1996 compared to the same periods in 1995 primarily due to parts
and equipment sales variances between the periods.

threatened to be made a party to any threatened, pending or completed action,
suit or proceeding whether civil, criminal, administrative or investigative
(other than an action by or in the right of the corporation) by reason of the
fact that he is or was a director, officer, employee or agent of the
corporation, or is or was serving at the request of the corporation, or is or
was serving at the request of the corporation as a director, officer, employee
or agent of another corporation, partnership, joint venture, trust or other
enterprise, against expenses (including attorneys' fees), judgments, fines and
amounts paid in settlement actually and reasonably incurred by him in connection
with such action, suit or proceeding if he acted in good faith and in a manner
he reasonably believed to be in or not opposed to the best interests of the
corporation, and, with respect to any criminal action or proceeding, had no
reasonable cause to believe his conduct was unlawful. The termination of any
action, suit or proceeding by judgment, order, settlement, conviction, or upon a
plea of NOLO CONTENDERS or its equivalent, shall not, of itself, create a
presumption that the person did not act in good faith and in a manner which he
reasonably believed to be in or not opposed to be the best interests of the
corporation, and, with respect to any criminal action or proceeding, had
reasonable cause to believe that his conduct was unlawful.

                                      9

      The corporation shall indemnify each of its directors in their capacity as
directors or officers of the corporation, and may indemnify any other person,
who was or is a party or is threatened to be made a party to any threatened,
pending or completed action or suit by or in the right of the corporation to
procure a judgment in its favor by reason of the fact that he is or was a
director, officer, employee or agent of the corporation, or is or was serving at
the request of the corporation as a director, officer, employee or agent of
another corporation, partnership, joint venture, trust or other enterprise
against expenses (including attorneys' fees) actually and reasonably incurred by
him in connection with the defense or settlement of such action or suit if he
acted in good faith and in a manner he reasonably believed to be in or not
opposed to the best interests of the corporation and except that no
indemnification shall be made in respect of any claim, issue or matter as to
which such person have been adjudged to be liable to the corporation unless and
only to the extent that the Court of Chancery of the court in which such action
or suit was brought shall determine upon application that, despite the
adjudication of liability but in view of all the circumstances of the case, such
person is fairly and reasonably entitled to indemnity for such expenses which
the Court of Chancery or such other court shall deem proper.

      Any indemnification under this section (unless ordered by a court) shall
be made by the corporation only upon a determination that indemnification of the
director, officer, employee or agent is proper because he has met the applicable
standard of conduct set forth above. Such determination shall be made as
follows: by the board of directors by a majority vote of directors who are not
parties to such action, suit or proceeding, even though such directors do not
constitute a quorum; or if such a quorum is not obtainable, or even if
obtainable a quorum of disinterested directors so directs, by independent legal
counsel in a written opinion, or by the stockholders.

      Expenses incurred by an officer or director in defending a civil or
criminal action, suit or proceeding may be paid by the corporation in advance of
the final disposition of such action, suit or proceeding as authorized by the
board of directors upon receipt of an undertaking by or on behalf of such
director or officer to repay such amount if it shall ultimately be determined
that he is not entitled to be indemnified by the corporation as authorized in
this section. Such expenses incurred by other employees and agents may be so
paid upon such terms and conditions, if any, as the board of directors deems
appropriate.

      The indemnification and advance of expenses provided by this section shall
be a contract right and shall not be deemed exclusive of any other rights to
which those seeking indemnification or the advancement of expenses may be
entitled under the laws of the State of Delaware, under any agreement, including
any agreement to which the corporation is a party, vote of stockholders or

interest due by the Borrower on all outstanding Eurodollar Rate Advances on the

Period from (B) the rate obtained by dividing such Eurodollar Rate referred to

Percentage of the Bank for such Interest Period. Such additional interest shall
be determined by the Bank as incurred and shall be payable upon demand therefor
by the Bank to the Borrower. Each determination by the Bank of additional
interest due under this Section shall be PRIMA FACIE evidence thereof for all
purposes in the absence of manifest error.

limitation, any fundings of Existing Letters of Credit for which the Bank is not
reimbursed (whether by application of the proceeds of Advances under SECTION
2.20(C) or otherwise) immediately by the Borrower for the account of which such
Existing Letter of Credit was issued (whether at stated maturity, by
acceleration or otherwise) shall bear interest from the date on which such
amount is due until such amount is paid in full at a rate per annum equal at all
times to the Prime Rate plus four percent (4%) per annum but in no event to
exceed the Highest Lawful Rate (the "DEFAULT RATE") and shall be payable upon
demand.

               (f) The Borrower shall, at the time of making each payment of
principal and/or interest hereunder and under the Note, specify to the Bank the
Advances or other sums payable by the Borrower hereunder or under the Note to
which such payment is to be applied and in the event that the Borrower fails to
so specify, the Bank may apply such payment to the Borrower's Obligations as it
may elect in its sole discretion.

               Section 2.06. INTEREST PERIODS. (a) At the time the Borrower
gives any Borrowing Request or Notice of Conversion in respect of the making of,
or conversion into, a Eurodollar Rate Advance, the Borrower shall have the right
to elect, by giving the Bank on the dates and at the times specified in SECTION
2.03 or SECTION 2.04, as the case may be, notice of the interest period (each an
"INTEREST PERIOD") applicable to such Eurodollar Rate Advance, which Interest
Period shall be either a one, two or three month period; PROVIDED, that:

                                      -20-

               (i) the initial Interest Period for any Eurodollar Rate Advance
        shall commence on the date of such Eurodollar Rate Advance (including
        the date of any conversion thereto or continuance thereof pursuant to
        SECTION 2.04); each Interest Period occurring thereafter in respect of
        such Eurodollar Rate Advance shall commence on the day following the
        expiration date of the immediately preceding Interest Period;

               (ii) if any Interest Period relating to a Eurodollar Rate Advance
        begins on a day for which there is no numerically corresponding day in
        the calendar month at the end of such Interest Period, such Interest
        Period shall end on the last Business Day of such calendar month;

               (iii) if any Interest Period would otherwise expire on a day
        which is not a Business Day, such Interest Period shall expire on the
        next succeeding Business Day; PROVIDED, that if there are no more
        Business Days in that month, the Interest Period shall expire on the
        preceding Business Day; and

               (iv) no Interest Period for Advances shall extend beyond the
        Maturity Date.

               (b) If, upon the expiration of any Interest Period applicable to
a Eurodollar Rate Advance, the Borrower has failed to elect a new Interest
Period to be applicable to such Advance as provided above, the Borrower shall be
deemed to have elected to convert such Advance into a Prime Rate Advance
effective as of the day following the expiration date of such current Interest
Period.

               Section 2.07. INTEREST RATE NOT ASCERTAINABLE. In the event that
the Bank shall determine (which determination shall, absent manifest error, be
final, conclusive and binding upon all parties) that on any date for determining
the Eurodollar Rate for any Interest Period, by reason of any changes arising
after the date of this Agreement affecting the eurodollar interbank market or
the Bank's position in such market, adequate and fair means do not exist for
ascertaining the applicable interest rate on the basis provided for in the
definition of Eurodollar Rate, then, and in any such event, the Bank shall
forthwith give notice to the Borrower of such determination. Until the Bank
notifies the Borrower that the circumstances giving rise to the suspension
described herein no longer exist, the obligations of the Bank to make Eurodollar
Rate Advances shall be suspended.

               Section 2.08. PRINCIPAL PAYMENTS OF ADVANCES. The unpaid
principal balance of the Advances, together with all accrued and unpaid interest
thereon, shall be due and payable on the Maturity Date, subject to the mandatory
prepayments required pursuant to SECTION 2.17.

               Section 2.09. COMPUTATIONS; PAYMENTS ON NON-BUSINESS DAYS. (a)
All payments by the Borrower of principal and interest hereunder, under the Note
and the other Loan

                                      -21-

Documents shall be made in U.S. Dollars to the Bank at its office at 712 Main
Street, Houston, Texas in immediately available funds not later than 12:00 noon
(Houston, Texas time) on the date when due.

               (b) Interest on the Prime Rate Advances shall be computed by the
Bank on the actual number of days elapsed over a year of 365 days, unless such
computation would cause the interest contracted for, charged or received to
exceed the Highest Lawful Rate, in which event, interest shall be computed for
the actual number of days elapsed over a year of 365 or 366 days, as the case
may be. Determination by the Bank of an interest rate hereunder shall be PRIMA
FACIE evidence of its accuracy.

               (c) Whenever any payment hereunder (other than payments of
interest on Eurodollar Rate Advances) shall be stated to be due on a day other
than a Business Day, such payment shall be made on the next succeeding Business
Day and such extension of time shall in such case be included in the computation
of payment of interest, the Commitment Fee, the L/C Fees and all other amounts
due under the Loan Documents, as the case may be.

               Section 2.10. SET-OFF, COUNTERCLAIMS AND TAXES. All payments of
principal, interest, expenses, reimbursements, compensation and any other amount
from time to time due hereunder, under the Note or any other Loan Document shall
be made by the Borrower without set-off or counterclaim and shall be made free
and clear of and without deduction for any present or future tax, levy, impost
or any other charge, if any, of any nature whatsoever now or hereafter imposed
by any taxing authority upon the Borrower. If the making of such payments by the
Borrower is prohibited by law unless such a tax, levy, impost or other charge is
deducted or withheld therefrom, the Borrower shall pay to the Bank, on the date
of each such payment, such additional amounts as may be necessary in order that
the net amounts received by the Bank after such deduction or withholding shall
equal the amounts which would have been received if such deduction or
withholding were not required; PROVIDED, HOWEVER, that all amounts payable under
this Agreement which constitute interest under applicable law shall not exceed
an amount which would result in the payment of interest at a rate in excess of
the Highest Lawful Rate.

               Section 2.11. THE BORROWER UNCONDITIONALLY LIABLE. (a) Subject to
the provisions of SECTIONS 9.11, 2.01(E) and 2.02, the Borrower and JVOI shall
(to the extent set forth herein) be unconditionally liable to the Bank for the
principal amount of any and all Advances made to it under the Note, and all
Existing L/C Obligations with respect to Existing Letters of Credit issued for
their respective accounts, interest due thereon, the L/C Fees relating thereto,
the Commitment Fee, and all other amounts due to the Bank from the Borrower or
JVOI, as the case may be hereunder or under any other agreement or security
document executed in connection herewith, and shall make prompt and punctual
payment when due of such amounts.

                                      -22-

               (b) Notwithstanding anything herein contained, JVOI shall be
primarily and principally liable for all amounts owed in respect of the JVOI
Letter of Credit. The Borrower, by its execution hereof, does hereby absolutely
and unconditionally, jointly and severally with all other Guarantors, guaranty
the Obligations of JVOI with respect to the JVOI Letter of Credit and agrees
that, it shall pay same according to their terms. The Borrower does hereby
incorporate into this Section all of the terms, conditions, waivers and
agreements set forth in ARTICLE III hereof and agrees that same shall govern
this guaranty of JVOI's obligations in respect of the JVOI Letter of Credit.

               Section 2.12. CHANGE IN LEGALITY. (a) Notwithstanding anything to
the contrary herein contained, if any change in any law or regulation or in the
interpretation thereof by any governmental authority charged with the
administration or interpretation thereof shall make it unlawful for the Bank or
its Eurodollar Lending Office to make or maintain any Eurodollar Rate Advance or
to give effect to its obligations as contemplated hereby with respect to
Eurodollar Rate Advances, then, by prompt written notice to the Borrower, the
Bank may:

               (i) declare that Eurodollar Rate Advances will not thereafter be
        made by the Bank hereunder, whereupon the Borrower shall be prohibited
        from requesting Eurodollar Rate Advances from the Bank hereunder unless
        such declaration is subsequently withdrawn; and

               (ii) in the event that the maintenance of any Eurodollar Rate
        Advance(s) shall have been made unlawful, require that all outstanding
        Eurodollar Rate Advance(s) made by the Bank be converted to Prime Rate
        Advances, in which event (A) all such Eurodollar Rate Advances shall be
        automatically converted to Prime Rate Advances as of the effective date
        of such notice as provided in paragraph (b) below and (B) all payments
        and prepayments of principal which would otherwise have been applied to
        repay the converted Eurodollar Rate Advances shall instead be applied to
        repay the Prime Rate Advances resulting from the conversion of such
        Eurodollar Rate Advances.

               (b) For purposes of this Section, a notice to the Borrower by the
Bank pursuant to paragraph (a) above shall be effective on the date of receipt
thereof by the Borrower.

               Section 2.13. RESERVE REQUIREMENTS; CHANGE IN CIRCUMSTANCES. (a)
It is understood that the cost to the Bank of making or maintaining any Advance
or Existing Letter of Credit may fluctuate as a result of the applicability of,
or changes in, reserve requirements imposed by the Board. The Borrower agrees to
pay to the Bank from time to time, as provided in paragraph (d) below, such
amounts as shall be necessary to compensate the Bank, prospectively from the
date of demand, for the portion of the cost of making or maintaining any Advance
or Existing Letter of Credit resulting from any such reserve requirements to the
extent set forth in this Section.

                                      -23-

               (b) Notwithstanding any other provision herein, if after the date
of this Agreement, the introduction of any applicable law or regulation or any
change in applicable law or regulation or in the interpretation or
administration thereof by any governmental authority charged with the
interpretation or administration thereof, or compliance by the Bank with any
applicable guideline or request from any central bank or governmental authority
(whether or not having the force of law) (i) shall change the basis of taxation
of payments to the Bank of the principal of or interest on any Advance made by
the Bank, any Existing L/C Obligations, any L/C Obligations or any other fees or
amounts payable hereunder (other than (x) taxes imposed on the overall net
income of the Bank or its applicable lending office by any jurisdiction or by
any political subdivision or taxing authority therein (or any tax which is
enacted or adopted by any such jurisdiction, political subdivision or taxing
authority as a direct substitute for any such taxes) or (y) any tax, assessment
or other governmental charge that would not have been imposed but for the
failure of the Bank to comply with any certification, information, documentation
or other reporting requirement), (ii) shall impose, modify or deem applicable
any reserve, special deposit or similar requirement against assets of, deposits
with or for the account of, or credit extended by, the Bank (without duplication
of any amounts paid pursuant to SECTION 2.05(D)), or (iii) shall impose on the
Bank any other condition affecting this Agreement or any Advance made by the
Bank, and the result of any of the foregoing shall be to increase the cost to
the Bank of maintaining the Commitment or of making or maintaining any Advance
or issuing or maintaining any Existing Letter of Credit or to reduce the amount
of any sum received or receivable by the Bank hereunder (whether of principal,
interest or otherwise) in respect thereof by an amount deemed in good faith by
the Bank to be material, then the Borrower shall pay to the Bank such additional
amount or amounts as will compensate the Bank for such increase or reduction
relating to any Commitment, Advance, or Existing Letter of Credit upon demand by
the Bank. Notwithstanding the foregoing, in no event shall the Bank be permitted
to receive any compensation hereunder constituting interest in excess of the
Highest Lawful Rate.

               (c) If the Bank shall have determined in good faith that any law,
rule, regulation or guideline adopted pursuant to or arising out of the July
1988 Report of the Basle Committee on Banking Regulations and Supervisory
Practices entitled "International Convergence of Capital Measurement and Capital
Standards" or that the adoption of any applicable law, rule, regulation or
guideline regarding capital adequacy, or any change in any of the foregoing or
in the interpretation or administration thereof by any central bank or other
governmental authority charged with the interpretation or administration
thereof, or compliance by the Bank with any request or directive regarding
capital adequacy (whether or not having the force of law) of any such central
bank or governmental authority, affects or would affect the amount of capital
required or expected to be maintained by the Bank or any corporation controlling
the Bank and that the amount of such capital is increased by or based upon the
existence of the Commitment hereunder and other commitments of this type, then
the Borrower shall from time to time pay to the Bank upon demand additional
amounts sufficient to compensate the Bank or such corporation in the light of
such circumstances, to the extent that

                                      -24-

the Bank reasonably determines such increase in capital to be allocable to the
existence of the Commitment hereunder.

               (d) If while any Existing Letter of Credit is outstanding, any
law, executive order or regulation is enforced, adopted or interpreted by any
central bank or other governmental authority so as to affect the Borrower's
obligations or the compensation to the Bank in respect of the Existing Letters
of Credit or the cost to the Bank of establishing or maintaining the Existing
Letters of Credit, then the Borrower shall from time to time upon demand,
reimburse or indemnify the Bank with respect thereto so that the Bank shall be
in the same position as if there had been no such enforcement, adoption or
interpretation. Notwithstanding the foregoing, in no event shall the Bank be
permitted to receive any compensation hereunder constituting interest in excess
of the Highest Lawful Rate.

               (e) The Bank will notify the Borrower of any event occurring
after the date of this Agreement which will entitle the Bank to compensation
pursuant to this SECTION 2.13. A certificate of the Bank setting forth in
reasonable detail (i) such amount or amounts as shall be necessary to compensate
the Bank as specified in paragraph (a), (b), (c) or (d) above as the case may
be, and (ii) the calculation of such amount or amounts shall be simultaneously
delivered to the Borrower owing such amount or amounts and shall be PRIMA FACIE
evidence of its accuracy. The Borrower shall pay to the Bank the amount shown as
due on any such certificate within ten (10) days after its receipt of the same.
The failure of the Bank to demand increased compensation with respect to any
Interest Period shall not constitute a waiver of the right to demand
compensation thereafter.

               Section 2.14. EURODOLLAR ADVANCE PREPAYMENT AND DEFAULT
PENALTIES. Subject to SECTION 9.11, the Borrower shall indemnify the Bank
against any reasonable loss or expense which it may actually sustain or incur as
a consequence of (a) an Advance of, or a conversion from or into, Eurodollar
Rate Advances that does not occur on the date specified therefor in a Borrowing
Request or Notice of Conversion (except by reason of SECTION 2.12) or (b) any
payment, prepayment or conversion of a Eurodollar Rate Advance required by any
other provision of this Agreement or otherwise made on a date other than the
last day of the applicable Interest Period (except for any conversion under
SECTION 2.12). Such loss or expense shall include an amount equal to the excess
determined by the Bank of (i) its actual cost of obtaining the funds for the
Advance being paid, prepaid or converted or not borrowed (based on the
Eurodollar Rate) for the period from the date of such payment, prepayment or
conversion or failure to borrow to the last day of the Interest Period for such
Advance (or, in the case of a failure to borrow, the Interest Period for the
Advance which would have commenced on the date of such failure to borrow) OVER
(ii) the amount of interest (as reasonably determined by the Bank) that would be
realized in reemploying the funds so paid, prepaid or converted or not borrowed
for such period or Interest Period, as the case may be. The Bank will notify the
Borrower of any loss or expense which will entitle the Bank to compensation
pursuant to this

                                      -25-

Section, as promptly as possible after it becomes aware thereof, but failure to
so notify shall not affect the Borrower's liability therefor. A certificate of
the Bank setting forth any amount which it is entitled to receive pursuant to
this Section shall be delivered to the Borrower and shall be PRIMA FACIE
evidence of its accuracy. The Borrower shall pay to the Bank the amount shown as
due on any certificate within ten (10) days after its receipt of the same.
Without prejudice to the survival of any other obligations of the Borrower
hereunder, the obligations of the Borrower under this Section shall survive the
termination of this Agreement and the assignment of any of the Note.

               Section 2.15. USE OF PROCEEDS OF ADVANCES. The Borrower will use
the proceeds of all Advances made hereunder for working capital and to refinance
existing debt owed the Bank.

               Section 2.16. VOLUNTARY PREPAYMENTS. Upon at least three (3)
Business Days' prior written notice, the Borrower shall have the right to
voluntarily prepay Advances in whole or in part from time to time on the
following terms and conditions: (a) no Eurodollar Rate Advance may be prepaid
prior to the last day of its Interest Period unless, simultaneously therewith,
the Borrower pays to the Bank all sums necessary to compensate the Bank for all
costs and expenses resulting from such prepayment, as reasonably determined by
the Bank, described in SECTIONS 2.05(D), 2.13, and 2.14 hereof and (b) each
prepayment pursuant to this Section shall be applied first, to the payment of
accrued and unpaid interest, and then, to the outstanding principal of such
Advances as shall be designated by the Borrower.

               Section 2.17. MANDATORY PREPAYMENTS. (a) If any Borrowing Base
Certificate shall disclose the existence of a Borrowing Base Deficiency, the
Borrower, on the day that the delivery of such Borrowing Base Certificate is
required by SECTION 6.01(F), shall prepay a principal amount of outstanding
Advances equal to such Borrowing Base Deficiency.

               (b) If, on any day, the market valuation of the Inventory of the
Borrower, its Subsidiaries and the Joint Ventures included in the Borrowing
Base, based on the American Metals Market Composite Valuation or such other
source of value acceptable to the Bank, is less than or equal to ninety percent
(90%) of the market valuation of such Inventory as disclosed in the most recent
Borrowing Base Certificate required to be delivered pursuant to SECTION 6.01(F),
the Borrowing Base shall be recalculated by the Borrower as of such date using
such market valuations as of such date and, if such recalculation results in a
Borrowing Base Deficiency, the Borrower, on the third business day following the
date of such recalculation shall deliver a new Borrowing Base Certificate and,
as required by SECTION 6.01(F), shall prepay a principal amount of outstanding
Advances equal to such Borrowing Base Deficiency.

                                      -26-

               (c) Upon its receipt of any Excess Sales Proceeds, the Borrower
will remit payments in the amount of such Excess Sales Proceeds to the Bank as a
prepayment of the principal then owing on the Advances.

               (d) All sums collected in Borrower's lockbox shall be applied
daily as a prepayment of principal then owing on the Advances.

               Section 2.18. REDUCTION OF THE COMMITMENT. (a) The Borrower shall
have the right, upon at least three (3) Business Days' notice to the Bank, to
terminate in whole or reduce in part the Unutilized Commitment; PROVIDED, that
each partial reduction shall be in the aggregate amount of $250,000.00 and an
integral multiple of $250,000.00 in excess thereof.

               (b) The Commitment shall be permanently reduced by the amount of
all principal prepaid under SECTION 2.17(C) above, except for such prepayments
of Excess Sales Proceeds constituting Joint Venture distributions.

               (c) The Commitment shall be reduced automatically without further
action by any Person by the amount of all or any portion of an Existing Letter
of Credit which prior to the Termination Date either (i) expires and is not
replaced or (ii) is funded and reimbursed by the Borrower other than with the
proceeds of an Advance.

               (d) On the Maturity Date the Commitment shall be zero; PROVIDED,
HOWEVER, if any one or more Existing Letters of Credit outstanding on the
Maturity Date have a later expiration date, then the Commitment shall reduce to
a level equal to the sum of the undrawn face amount of each of the then
outstanding Existing Letters of Credit (reducing by the amount of any expiring
Existing Letter of Credit as it expires or is funded and reimbursed by the
Borrower) and shall, in any event, terminate in its entirety on the Extended
Termination Date.

               Section 2.19. FEES. (a) The Borrower agrees to pay to the Bank a
commitment fee (the "COMMITMENT FEE") for the period from and including the date
hereof to but not including the Maturity Date, computed at a rate equal to
one-quarter of one percent (1/4%) per annum (based on a 360 day year) on the
total Commitment. Such Commitment Fee shall be due and payable in arrears on the
last Business Day of each calendar quarter and on the Termination Date.

               (b) The Borrower shall pay to the Bank a letter of credit
commission with respect to each Existing Letter of Credit payable in advance and
computed for the period from the Effective Date or date of such payment to the
date upon which the next such payment is due hereunder at the rate of one
percent (1%) per annum (which shall be calculated on the basis of one-quarter of
one percent (1/4%) for each 90 day period or any part thereof) of the aggregate
amount available to be drawn under such Existing Letter of Credit on the date on
which such

                                      -27-

fee is calculated or the then minimum letter of credit insurance fee charged by
the Bank, whichever is greater; PROVIDED, HOWEVER, with respect to each Existing
Letter of Credit, the amount of such commission payable to the Bank shall be
paid at this rate from and after the Effective Date but shall be reduced by the
amount of the commissions already paid to the Bank with respect to such Existing
Letter of Credit with respect to any period from and after the Effective Date,
if any. Such commissions shall be payable in advance on the last day of each
calendar quarter and shall be nonrefundable.

               (c) The Borrower will pay to the Bank an administrative fee of
$100,000.00 on the Effective Date.

               The provisions of this SECTION 2.19(C) do not create and shall
not be construed to create any obligation on the part of the Bank to extend the
Maturity Date.

               (d) In addition to the foregoing fees and commissions, the
Borrower shall pay or reimburse the Bank for such normal and customary costs and
expenses as are incurred or charged by the Bank in issuing, effecting payment
under, amending or otherwise administering any Existing Letter of Credit.

               Section 2.20.  EXISTING LETTERS OF CREDIT.

               (a) The Bank shall not be required to issue any new letters of
credit (except for any of same that constitute renewals or replacements for the
letters of credit listed on EXHIBIT 1.01B, and are therefor "Existing Letters of
Credit").

               (b) In respect of any Existing Letters of Credit, if any,
outstanding on the Termination Date, assuming no Default or Event of Default has
occurred, the Borrower may, at its option, provide to the Bank collateral in the
form of cash or a certificate of deposit issued by the Bank in the amount of
such Existing Letters of Credit and any expenses reasonably anticipated by the
Bank in connection therewith, whereupon, when all such Existing Letters of
Credit are so secured, the Bank shall release its Liens on all other collateral
hereunder or under any of the Loan Documents. In no event shall any Existing
Letters of Credit be outstanding beyond the Extended Termination Date. The
Borrower shall remain liable in respect of the Existing Letters of Credit on
terms consistent with the terms hereof, but for all other purposes of this
Agreement and the other Loan Documents, the Obligations will be deemed paid in
full and not outstanding and the Commitment and the L/C Limit shall be deemed
terminated.

               (c) The Borrower agrees to reimburse the Bank on each date on
which the Bank notifies the Borrower of the date and amount of a draft presented
under any Existing Letter of Credit paid by the Bank for the amount of (i) such
draft so paid and (ii) any taxes, fees, charges or other costs or expenses
incurred by the Bank in connection with such payment. Upon

                                      -28-

the presentment of any draft for honor under any Existing Letter of Credit by
the beneficiary thereof which the Bank determines is in compliance with the
condition for payment thereunder, the Bank shall promptly notify the Borrower.
In the event the Bank makes any payment pursuant to a draft presented under an
Existing Letter of Credit, the Borrower shall immediately, upon demand, pay said
amount to the Bank in cash plus any interest due thereon from the date when due
at the Default Rate as provided in SECTION 2.05(E).

               (d) The Borrower's obligations under this Section shall be
absolute and unconditional under any and all circumstances and irrespective of
any set-off, counterclaim or defense to payment which the Borrower may have or
have had against the Bank or any beneficiary of an Existing Letter of Credit.
The Borrower also agrees with the Bank that the Bank shall not be responsible
for, and the Borrower's reimbursement obligations under SECTION 2.20(C) above
shall not be affected by, among other things, the validity or genuineness of
documents or of any endorsements thereon, even through such documents shall in
fact prove to be invalid, fraudulent or forged, or any dispute between or among
the Borrower and any beneficiary of any Existing Letter of Credit or any other
party to which such Existing Letter of Credit may be transferred or any claims
whatsoever of the Borrower against any beneficiary of such Existing Letter of
Credit or any such transferee. The Bank shall not be liable for any error,
omission, interruption or delay in transmission, dispatch or delivery of any
message or advice, however transmitted, in connection with any Existing Letter
of Credit, except for errors or omissions caused by the Bank's gross negligence
or willful misconduct. The Borrower agrees that any action taken or omitted by
the Bank under or in connection with any Existing Letter of Credit or the
related drafts or documents, if done in the absence of gross negligence or
willful misconduct and in accordance with the standards of care specified in the
Uniform Customs and, to the extent not inconsistent therewith, the Uniform
Commercial Code of the State of Texas, shall be binding on the Borrower and
shall not result in any liability of the Bank to the Borrower.

               (e) The responsibility of the Bank to the Borrower in connection
with any draft presented for payment under any Existing Letter of Credit shall,
in addition to any payment obligation expressly provided for in such Existing
Letter of Credit be limited to determining that the documents (including each
draft) delivered under such Existing Letter of Credit in connection with such
presentment are in conformity with such Existing Letter of Credit.

               (f) To the extent that any provision of any Application,
certificate, document or other papers related to any Existing Letter of Credit
is inconsistent with the provisions of this Agreement, the provisions of this
Agreement shall control and no such Application, certificate, document or other
paper shall give the Bank or the Borrower any greater rights than the Bank or
the Borrower would otherwise have under this Agreement.

                                      -29-

               Section 2.21. RATIFICATION. Each Credit Party hereby confirms and
ratifies the terms of the Security Documents to which it is a party and the
creation of the Liens thereunder to secure the Obligations of the Borrower to
the Bank and hereby regrants the security interests and Liens of same to secure
the Obligations as more fully set forth therein and further agrees and
acknowledges (a) that the Liens of the Security Documents to which it is a party
extend to and expressly secure the Obligations of the Borrower under this
Agreement, the Note and the other Loan Documents and (b) that the Security
Documents to which it is a party and the Liens created thereunder are valid and
subsisting and shall remain enforceable against such Credit Party in accordance
with their terms and shall not be reduced or limited or impaired by the

                                   ARTICLE III
                                    GUARANTY

               Section 3.01. GUARANTY. (a) In consideration of, and in order to
induce the Bank to make Advances and continue Existing Letters of Credit
hereunder, each Guarantor hereby absolutely, unconditionally and irrevocably,
jointly and severally guarantees the punctual payment and performance when due,
whether at stated maturity, by acceleration or otherwise, of all obligations and
covenants of the Borrower and, in respect of the JVOI Letter of Credit, the
obligations of JVOI, now or hereafter existing under this Agreement, the Note
and/or any of the other Loan Documents to which the Borrower or JVOI, as
applicable, is a party whether for principal, interest (including interest
accruing or becoming owing both prior to and subsequent to the commencement of
any proceeding against or with respect to the Borrower under any chapter of the
Bankruptcy Code of the United States (11 U.S.C. ss. 101 ET SEQ.) or any other
Debtor Relief Law, fees, commissions, expenses (including reasonable counsel
fees and expenses) or otherwise, and all reasonable costs and expenses, if any,
incurred by the Bank in connection with enforcing any rights under this Guaranty
(all such obligations being the "GUARANTEED OBLIGATIONS"); provided that the
Guaranteed Obligations of each Guarantor under this Guaranty shall not exceed an
amount that is $1.00 less than that amount that would render such Guarantor's
obligation under this Guaranty subject to avoidance under Section 548 of the U.
S. Bankruptcy Code or any comparable provisions of any applicable state or
foreign law. This Guaranty is an absolute, unconditional, present and continuing
guaranty of payment and not of collectibility and is in no way conditioned upon
any attempt to collect from the Borrower or any other action, occurrence or
circumstance whatsoever. Nothing herein is intended to provide that the Borrower
shall be liable as a Guarantor for any Obligations for which the Borrower is
primarily liable, but the Borrower shall be liable as a Guarantor for any
Obligations for which the Borrower is not primarily liable.

               (b) Each Guarantor hereby, jointly and severally, agrees to pay
and to indemnify the Bank harmless from and against any damage, loss, cost or
expense (including

                                      -30-

reasonable attorneys' fees) that the Bank may incur or be subject to as a
consequence, direct or indirect, of (i) any breach by such Guarantor or any
other Credit Party of any warranty, covenant, term or condition in, or the
occurrence of any default under, this Guaranty, this Agreement or any other Loan
Document, together with all reasonable expenses resulting from the compromise or
defense of any claims or liabilities arising as a result of any such breach or
default and (ii) any legal action commenced to challenge the validity of this
Guaranty, this Agreement or any other Loan Document.

               Section 3.02. CONTINUING GUARANTY. Each Guarantor guarantees that
the Guaranteed Obligations will be paid strictly in accordance with the terms of
this Agreement, the Note and the other Loan Documents. Each Guarantor agrees
that the Guaranteed Obligations and Loan Documents may be extended or renewed,
and that it will remain bound upon this Guaranty notwithstanding any extension,
renewal or other alteration of any Guaranteed Obligations or Loan Documents. The
obligations of each Guarantor under this Guaranty shall be absolute,
unconditional and irrevocable, and shall be performed strictly in accordance
with the terms hereof under any circumstances whatsoever, including:

               (a) any extension, renewal, modification, settlement, compromise,
waiver or release in respect of any Guaranteed Obligations, including any
reduction or termination of all or a portion of the Commitment;

               (b) any extension, renewal, amendment, modification, rescission,
waiver or release in respect of any Loan Documents;

               (c) any release, exchange, substitution, non-perfection or
invalidity of, or failure to exercise rights or remedies with respect to, any
direct or indirect security for any Guaranteed Obligations, including the
release of any Guarantor or other Person liable on any Guaranteed Obligations;

               (d) any change in the corporate existence, structure or ownership
of the Borrower, any Guarantor, or any insolvency, bankruptcy, reorganization or
other similar proceeding affecting the Borrower, such Guarantor, any other
Guarantor or any of their respective assets;

               (e) the existence of any claim, defense, set-off or other rights
or remedies which such Guarantor at any time may have against the Borrower, or
the Borrower or such Guarantor may have at any time against the Bank, any other
Guarantor or any other Person, whether in connection with this Guaranty, the
Loan Documents, the transactions contemplated thereby or any other transaction;

                                      -31-

               (f) any invalidity or unenforceability for any reason of this
Agreement or other Loan Documents, or any provision of law purporting to
prohibit the payment or performance by the Borrower, such Guarantor or any other
Guarantor of the Guaranteed Obligations or Loan Documents, or of any other
obligation to the Bank; or

               (g) any other circumstances or happening whatsoever, whether or
not similar to any of the foregoing.

               Section 3.03. EFFECT OF DEBTOR RELIEF LAWS. If, after receipt of
any payment of, or proceeds of any security applied (or intended to be applied)
to the payment of all or any part of the Guaranteed Obligations, the Bank is for
any reason compelled to surrender or voluntarily surrenders, such payment or
proceeds to any Person (a) because such payment or application of proceeds is or
may be voided, invalidated, declared fraudulent, set aside, determined to be
void or voidable as a preference, fraudulent conveyance, fraudulent transfer,
impermissible set-off or a diversion of trust fund, or (b) for any other reason,
including (i) any judgment, decree or order of any court or administrative body
having jurisdiction over the Bank or any of its properties or (ii) any
settlement or compromise of any such claim effected by the Bank with any such
claimant (including the Borrower), then the Guaranteed Obligations or part
thereof intended to be satisfied shall be reinstated and continue, and this
Guaranty shall continue in full force as if such payment or proceeds have not
been received, notwithstanding any revocation thereof or the cancellation of the
Note or any other instrument evidencing any Guaranteed Obligations or otherwise;
and the Guarantors, jointly and severally, shall be liable to pay the Bank, and
hereby do indemnify the Bank and hold it harmless for the amount of such payment
or proceeds so surrendered and all expenses (including reasonable attorneys'
fees, court costs and expenses attributable thereto) incurred by the Bank in the
defense of any claim made against it that any payment or proceeds received by
the Bank in respect of all or part of the Guaranteed Obligations must be
surrendered. The provisions of this paragraph shall survive the termination of
this Guaranty, and any satisfaction and discharge of the Borrower by virtue of
any payment, court order or any federal or state law.

               Section 3.04. WAIVER OF SUBROGATION. Notwithstanding any payment
or payments made by any Guarantor hereunder, or any set-off or application by
the Bank of any security or of any credits or claims, no Guarantor will assert
or exercise any rights of the Bank or of such Guarantor against the Borrower or
any other Guarantor to recover the amount of any payment made by such Guarantor
to the Bank hereunder by way of subrogation, reimbursement, contribution,
indemnity, or otherwise arising by contract or operation of law, until such time
as the Obligations have been satisfied and the Bank shall have no Commitment. If
any amount shall nevertheless be paid to a Guarantor by the Borrower or another
Guarantor prior to payment in full of the Guaranteed Obligations, such amount
shall be held in trust for the benefit of the Bank and shall forthwith be paid
to the Bank to be credited and applied to the Guaranteed Obligations, whether
matured or unmatured.

                                      -32-

               Section 3.05. SUBORDINATION. Each Guarantor hereby subordinates
all indebtedness owing to it from the Borrower to all indebtedness of the
Borrower to the Bank, and agrees that it shall not accept any payment on the
same until payment in full of the obligations of the Borrower under this
Agreement, the Notes, the Existing Letters of Credit and all other Loan
Documents, and shall in no circumstance whatsoever attempt to set-off or reduce
any obligations hereunder because of such indebtedness. If any amount shall
nevertheless be paid to a Guarantor by the Borrower or another Guarantor prior
to payment in full of the Guaranteed Obligations, such amount shall be held in
trust for the benefit of the Bank and shall forthwith be paid to the Bank to be
credited and applied to the Guaranteed Obligations, whether matured or
unmatured.

               Section 3.06. WAIVER. Each Guarantor hereby waives promptness,
diligence, notice of acceptance and any other notice with respect to any of the
Guaranteed Obligations and this Guaranty and waives presentment, demand of
payment, notice of intent to accelerate, notice of dishonor or nonpayment and
any requirement that the Bank institute suit, collection proceedings or take any
other action to collect the Guaranteed Obligations, including any requirement
that the Bank protect, secure, perfect or insure any Lien against any property
subject thereto or exhaust any right or take any action against the Borrower or
any other Person or any collateral (it being the intention of the Bank and each
Guarantor that this Guaranty is to be a guaranty of payment and not of
collection). It shall not be necessary for the Bank, in order to enforce any
payment by any Guarantor hereunder, to institute suit or exhaust its rights and
remedies against the Borrower, any other Guarantor or any other Person,
including others liable to pay any Guaranteed Obligations, or to enforce its
rights against any security ever given to secure payment thereof. Each Guarantor
hereby expressly waives each and every right to which it may be entitled by
virtue of the suretyship laws of the State of Texas, including, without
limitation, any and all rights it may have pursuant to Rule 31, Texas Rules of
Civil Procedure, Section 17.001 of the Texas Civil Practice and Remedies Code
and Chapter 34 of the Texas Business and Commerce Code. Each Guarantor hereby
waives marshaling of assets and liabilities, notice by the Bank of any
indebtedness or liability to which the Bank applies or may apply any amounts
received by the Bank, and of the creation, advancement, increase, existence,
extension, renewal, rearrangement and/or modification of the Guaranteed
Obligations. Each Guarantor expressly waives, to the extent permitted by
applicable law, the benefit of any and all laws providing for exemption of
property from execution or for valuation and appraisal upon foreclosure.

               Section 3.07. FULL FORCE AND EFFECT. This Guaranty is a
continuing guaranty and shall remain in full force and effect until payment in
full of the Obligations of the Borrower under this Agreement, the Note and all
other Loan Documents and all other amounts payable under this Guaranty.

                                      -33-

performance by such Credit Party of each of the Loan Documents to which it is or

in such Credit Party's articles or certificate of incorporation or bylaws, or
contained in any material agreement, instrument or document to which it is a
party or by which it is bound, other than violations or breaches which would
not, individually or in the aggregate, result in a Material Adverse Effect or

Documents).

               Section 5.04. CONSENTS. No authorization, consent, approval,
permit, license, or exemption of or filing or registration with, any
governmental agency or any other Person which has not been obtained, was, is or

taken as a whole except as to those matters previously disclosed to the Bank as
of the date hereof.

               Section 5.06. LITIGATION; MATERIAL ADVERSE EFFECT. (a) Except as
set forth in EXHIBIT 5.06 hereto, there are no actions, suits or proceedings
pending or, to the best of the Borrower's knowledge, threatened or probable of

any property or rights of any Credit Party or any of its Subsidiaries before any
court or any governmental department, commission, board, bureau, agency or

Subsidiaries, as the case may be, has good record and defensible title in fee
simple to or valid leasehold interests in all its real properties and marketable
title to all its other property and assets except where the failure to so have
such title or interest would not reasonably be expected to have a Material

the Borrower and other tax returns and reports of each Credit Party and its
Subsidiaries required to be filed with the appropriate governmental agencies in

amount equal to the aggregate undrawn face amount of such Existing Letters of
Credit issued for its account. Amounts held in such cash collateral account
shall be applied by the Bank to the payment of drafts drawn under such Existing
Letters of Credit, and the unused portion thereof after all such Existing
Letters of Credit shall have expired or been fully drawn upon, if any, shall be
applied to repay other obligations of the Borrower hereunder and under the Note
and the other Loan Documents. After all such Existing Letters of Credit shall
have expired or been fully drawn upon, Existing L/C Obligations shall have been
satisfied and all other obligations of the Borrower hereunder and under the
Notes and the other Loan Documents shall have been paid in full, the balance, if
any, in such cash collateral account shall be returned to the Borrower that

any other Credit Party (any such notice being expressly waived by the Credit
Party) and to the fullest extent permitted by applicable law, to set-off and
apply any and all deposits (general or special, time or demand, provisional or
final) at any time held and other indebtedness at any time owing by the Bank or
any branch, subsidiary or Affiliate of the Bank to or for the credit or the
account of any Credit Party against any and all of the obligations of such
Credit Party, now or hereafter existing under this Agreement (including all
Existing L/C Obligations), the Note or the other Loan Documents to which each
such Credit Party is a party, irrespective of whether or not the Bank shall have
made any demand for satisfaction of such Obligations and although such
Obligations may be unmatured. The Bank agrees to notify the Borrower promptly
after any such set-off and application made by the Bank; PROVIDED, HOWEVER, that
the failure to give such notice shall not affect the validity of such set-off
and application. The rights of the Bank under this Section are in addition to
other rights and remedies (including other rights of set-off) which the Bank may
have hereunder or under any applicable law.

                                   ARTICLE IX

Communication to each of the other parties hereto. All Communications shall be
effective, in the case of written or telecopied communications, three days after
being deposited in the mail, or upon the date sent by telecopy or (in the case
of Communications which are not mailed or telecopied) when

                                      -60-

delivered and (if a Communication is sent by telecopy or delivered) receipt
thereof is confirmed, respectively, in each case addressed as aforesaid.
Notwithstanding the foregoing, all Borrowing Requests shall not be effective
until received by the Bank.

               Section 9.03. COSTS, EXPENSES AND TAXES. The Borrower agrees to
pay on demand all reasonable costs and expenses of the Bank in connection with
(a) the administration of the Loan Documents, the Letters of Credit and the
preparation, execution, delivery, filing, recording and administration of this
Agreement, the Advances, the Note, the Existing Letters of Credit and the other
Loan Documents and any other agreements or security documents delivered in
connection with or pursuant to any of the Loan Documents, including the
reasonable fees and out-of-pocket expenses of Andrews & Kurth L.L.P., counsel
for the Bank and any local counsel who may be retained by such counsel, and the
cost of any and all appraisals, surveys, environmental audits or studies subject
to the limitations of SECTION 6.01(L), title insurance policies and similar
items required hereby, (b) all reasonable costs and expenses, if any, incurred
by the Bank in connection with the enforcement of this Agreement and the other
Loan Documents and any other agreements or security documents executed in
connection with or pursuant to any of the Loan Documents, including the
reasonable fees and out-of-pocket expenses of counsel for the Bank and any local
counsel who may be retained by such counsel, and (c) the reasonable costs and
expenses in connection with the custody, preservation, use or operation of, or
the sale of, or collection from, or other realization upon the collateral
covered by any of the Loan Documents. The agreements of the Borrower contained
in this Section shall survive the termination of the Commitment and the payment
of all amounts owing by any Credit Party hereunder or under any of the other
Loan Documents.

               Section 9.04. BINDING EFFECT; SUCCESSORS AND ASSIGNS. This
Agreement shall be binding upon and inure to the benefit of the Credit Parties,
the Bank and their respective successors and assigns, except that no Credit
Party may assign or transfer its respective rights hereunder without the prior
written consent of the Bank.

               Section 9.05. INDEPENDENCE OF COVENANTS. All covenants contained
in the Loan Documents shall be given independent effect so that if a particular
action or condition is not permitted by any of such covenants, the fact that
such action or condition would be permitted by an exception to, or otherwise be
within the limitations of, another covenant shall not avoid the occurrence of a
Default or an Event of Default if such action is taken or condition exists.

               Section 9.06. SURVIVAL OF REPRESENTATIONS AND WARRANTIES. All
representations and warranties contained in this Agreement and the other Loan
Documents, or made in writing by any Credit Party in connection herewith or
therewith, shall survive the execution and delivery of this Agreement, the Note,
the Existing Letters of Credit and the other Loan Documents. Any investigation
by the Bank shall not diminish in any respect whatsoever its right to rely on
such representations and warranties.

                                      -61-

               Section 9.07. SEPARABILITY. Should any clause, sentence,
paragraph, subsection, Section or Article of this Agreement be judicially
declared to be invalid, unenforceable or void, such decision will not have the
effect of invalidating or voiding the remainder of this Agreement, and the
parties hereto agree that the part or parts of this Agreement so held to be
invalid, unenforceable or void will be deemed to have been stricken herefrom by
the parties hereto, and the remainder will have the same force and effectiveness
as if such stricken part or parts had never been included herein.

               Section 9.08. NO WAIVER; REMEDIES. No failure on the part of the
Bank to exercise, and any delay in exercising, any right hereunder shall operate
as a waiver thereof, nor shall any single or partial exercise of any right
hereunder preclude any other or further exercise thereof or the exercise of any
other right. The remedies provided in this Agreement and the Note are cumulative
and not exclusive of any remedies provided in any of the other Loan Documents or
by law.

               Section 9.09. COUNTERPARTS. This Agreement may be executed in any
number of counterparts and by different parties hereto in separate counterparts,
each of which when so executed shall be deemed to be an original, and all of
which taken together shall constitute one and the same agreement.

               Section 9.10. GOVERNING LAW. This Agreement, the Note, the
Existing Letters of Credit and, unless otherwise specified therein, all other
Loan Documents and all other documents executed in connection herewith or
therewith, shall be deemed to be contracts and agreements executed by Credit
Parties and the Bank under the laws of the State of Texas and of the United
States and for all purposes shall be construed in accordance with, and governed
by, the laws of the State of Texas and of the United States. Without limitation
of the foregoing, nothing in this Agreement, the Note or any other Loan
Documents shall be deemed to constitute a waiver of any rights which the Bank
may have under federal legislation relating to the rate of interest which the
Bank may contract for, take, receive, reserve or charge in respect of any
Advance or any of the Obligations. The Bank and the Borrower further agree that
insofar as the provisions of Article 1.04, Subtitle 1, Title 79, of the Revised
Civil Statutes of Texas, 1925, as amended, are applicable to the determination
of the Highest Lawful Rate with respect to the Obligations, the indicated
(weekly) rate ceiling computed from time to time pursuant to Section (a) of such
Article shall apply to the other Obligations; PROVIDED, HOWEVER, that to the
extent permitted by such Article, the Bank may from time to time by notice from
the Bank to the Borrower revise the election of such interest rate ceiling as
such ceiling affects the then current or future balances outstanding under the
Note. The provisions of Chapter 15 of Subtitle 3 of the said Title 79 do not
apply to this Agreement, the Note or any transactions contemplated by any Loan
Document.

                                      -62-

               Section 9.11. LIMITATION ON INTEREST. Each provision in this
Agreement, the Note, the Existing Letters of Credit and each other Loan Document
is expressly limited so that in no event whatsoever shall the amount paid, or
otherwise agreed to be paid, to the Bank for the use, forbearance or detention
of the money to be advanced under this Agreement, the Note or any other Loan
Document or otherwise (including any sums paid as required by any covenant or
obligation contained herein or in any other Loan Document which is for the use,
forbearance or detention of such money), exceed that amount of money which would
cause the effective rate of interest to exceed the Highest Lawful Rate, and all
amounts owed under this Agreement and each other Loan Document shall be held to
be subject to reduction to the effect that such amounts so paid or agreed to be
paid which are for the use, forbearance or detention of money under this
Agreement or such Loan Document shall in all events be less than that amount of
money which would cause the effective rate of interest to exceed the Highest
Lawful Rate. Anything in this Agreement, the Note, the Existing Letters of
Credit or any other Loan Document to the contrary notwithstanding, the Borrower
shall never be required to pay unearned interest on the Advances or any of the
other Obligations or ever be required to pay interest on the Advances or any of
the other Obligations at a rate in excess of the Highest Lawful Rate, or if the
holder of any of the Advances or any of the other Obligations shall receive any
unearned interest or shall receive monies that are deemed to constitute interest
which would increase the effective rate of interest payable by the Borrower
under this Agreement, the Note and the other Loan Documents to a rate in excess
of the Highest Lawful Rate, then (a) the amount of interest which would
otherwise be payable by the Borrower under this Agreement, the Note and other
Loan Documents shall be reduced to the amount allowed under applicable law and
(b) any unearned interest paid by the Borrower or any interest paid by the
Borrower in excess of the Highest Lawful Rate shall be in the first instance
credited on the principal of the applicable Note with the excess thereof, if
any, refunded to the Borrower. It is further agreed that, without limitation of
the foregoing, all calculations of the rate of interest contracted for, charged
or received by the Bank under the Note, this Agreement, the Existing Letters of
Credit or the other Loan Documents, are made for the purpose of determining
whether such rate exceeds the Highest Lawful Rate, and shall be made, to the
extent permitted by usury laws applicable to the Bank (now or hereafter
enacted), by amortizing, prorating, allocating and spreading in equal parts
during the period of the full stated term of the Obligations evidenced by the
Note all interest at any time contracted for, charged or received by the Bank in
connection therewith. If, at any time and from time to time, (x) the amount of
interest payable to the Bank on any date shall be computed at the Highest Lawful
Rate pursuant to this Section and (y) in respect of any subsequent interest
computation period the amount of interest otherwise payable to the Bank would be
less than the amount of interest payable to the Bank computed at the Highest
Lawful Rate, then to the extent permitted by applicable usury law, the amount of
interest payable to the Bank in respect of such subsequent interest computation
period shall continue to be computed at the Highest Lawful Rate until the total
amount of interest payable to the Bank shall equal the total amount of interest
which would have been payable to the Bank if the total amount of interest had
been computed without giving effect to this Section.

                                      -63-

               Section 9.12. INDEMNIFICATION. (a) The Borrower and each other
Credit Party agrees to indemnify, defend and hold the Bank, as well as its
officers, employees, agents, directors, shareholders, counsels and Affiliates
(collectively, "INDEMNIFIED PERSONS") harmless from and against any and all
loss, liability, damage, judgment, claim, deficiency, penalty, fine, response
and remediation cost, stabilization cost, encapsulation cost, treatment, storage
or disposal cost, groundwater monitoring or environmental sampling cost or any
other reasonable cost or expense (including interest, penalties, reasonable
attorneys', experts' or consultants' fees, and disbursements in connection with
any investigative, administrative or judicial proceeding and amounts paid in
settlement) (collectively, "INDEMNIFIED LIABILITIES") incurred by or asserted
against any Indemnified Person arising out of, in any way connected with, or as
a result of (i) the execution and delivery of this Agreement and the other Loan
Documents, the performance by the parties hereto and thereto of their respective
obligations hereunder and thereunder (including the making of the Commitment of
the Bank) and consummation of the transactions contemplated hereby and thereby,
(ii) the actual or proposed use of the Existing Letters of Credit or the
proceeds of the Advances, (iii) any past, present or future violation by the
Borrower, any of its respective Subsidiaries, any operator who is not an
Indemnified Person of the Mortgaged Properties, or any other Person (other than
any Indemnified Person) of any requirement of law, including Environmental Laws,
with regard to the ownership, operation, use or occupancy of the Mortgaged
Properties occurring at any time prior to the repayment in full of the Advances
and the other Obligations, (iv) solely insofar as any of the following arises
out of any Mortgaged Property, the past, present or future treatment, storage,
disposal, generation, use, transport, movement, migration, presence, release,
spill or emission of any pollutants, contaminants, Hazardous Materials, or
hazardous or toxic substances or wastes into or onto soil, land, surface water,
ground water, watercourses, publicly-owned treatment works, drains, sewer
systems, wetlands or septic systems occurring at any time prior to the repayment
in full of the Advances and the other Obligations, (v) ownership by the Bank of
any real or personal property following rightful foreclosure under the Security
Documents, to the extent such losses, liabilities, damages, judgments, claims,
deficiencies or expenses arise out of or result from the presence or release of
any Hazardous Materials in, on or under such property during the period owned,
leased or operated by the Borrower or any of its respective Subsidiaries,
including, without limitation, losses, liabilities, damages, judgments, claims,
deficiencies or expenses which are imposed under Environmental Laws upon Persons
by virtue of their ownership, (vi) foreseeable consequential or punitive damages
incurred as a result of any matter or claim described above or (vii) any claim,
litigation, investigation or proceeding relating to any of the foregoing,
whether or not any Indemnified Person is a party thereto.

               (b) WITHOUT LIMITING ANY PROVISION OF THIS AGREEMENT OR ANY OF
THE OTHER LOAN DOCUMENTS BUT IN ALL EVENTS SUBJECT TO SUBPARAGRAPH (C) OF THIS
SECTION 9.12, IT IS THE EXPRESS INTENTION OF THE BORROWER AND THE OTHER CREDIT
PARTIES THAT EACH INDEMNIFIED PERSON SHALL BE INDEMNIFIED AND HELD HARMLESS
AGAINST ANY AND

                                      -64-

ALL LOSSES, LIABILITIES, CLAIMS, DEFICIENCIES, JUDGMENTS OR REASONABLE EXPENSES
ARISING OUT OF OR RESULTING FROM THE ORDINARY NEGLIGENCE (WHETHER SOLE OR
CONTRIBUTORY) OF SUCH INDEMNIFIED PERSON. THE OBLIGATIONS OF THE BORROWER AND
THE OTHER CREDIT PARTIES UNDER THIS SECTION 9.12 SHALL SURVIVE THE TERMINATION
OF THIS AGREEMENT AND THE COMMITMENT AND THE REPAYMENT OF THE OBLIGATIONS.

               (c) Notwithstanding any other provision of this Agreement or any
other Loan Document or any other document or instrument, in no event shall any
Credit Party be liable in any manner with respect to any or all Indemnified
Liabilities to the extent arising from any acts or omissions constituting gross
negligence or willful misconduct on the part of any Indemnified Person.

               (d) With respect to all Indemnified Liabilities relating to any
Mortgaged Property or any Hazardous Material or any Environmental Law,
notwithstanding any other provision of this Agreement or any other Loan Document
or any other document or instrument, no Credit Party shall be liable (x) for any
acts of any Indemnified Person or of any Person acting on behalf of or at the
direction of any Indemnified Person, or (y) in the event that any Indemnified
Person, or any Person acting on behalf of or at the direction of any Indemnified
Person, is judicially or administratively determined to be a Person having
management participation or otherwise exercising control within the meaning of
the Environmental Laws in effect on the date of this Agreement, for any omission
of any Indemnified Person or any omission of any Person acting on behalf of, or
at the direction of any Indemnified Person, or (z) for any act or omission of
any Person occurring from and after the date on which none of the Credit Parties
holds title to such Mortgaged Property; PROVIDED, HOWEVER, that this clause (z)
shall not release any Credit Party from any liability which it would otherwise
have under this subparagraph (d) for conditions arising prior to said date as to
which any Indemnified Liability is asserted subsequent to said date.

               Section 9.13. NOTICE AND DEFENSE OF CLAIMS. (a) The Credit
Parties shall give prompt notice to the Bank of:

               (i) their receipt of any correspondence, demand, notice, order,
        complaint, notice of violation, assessment, claim or request for
        information issued pursuant to or under color of any Environmental Laws
        or which refers to any Hazardous Materials from any federal, state or
        local governmental authority or from any private party or organization
        with respect to the Mortgaged Properties, any operator of the Mortgaged
        Properties or any Credit Party, which, in the reasonable good faith
        judgment of the Credit Parties, is likely to result in a Material
        Adverse Effect;

                                      -65-

               (ii) the institution of any claim, suit, action, investigation or
        administrative or judicial proceeding or action (formal or informal) of
        which the Credit Parties are aware, brought with regard to the
        condition, use, ownership, operation, occupancy or maintenance of the
        Mortgaged Properties under the Environmental Laws or relating to
        Hazardous Materials which claim, suit, action, investigation or
        administrative or judicial proceeding or action, in the reasonable good
        faith judgment of the Credit Parties, is likely to result in a Material
        Adverse Effect; and

               (iii) the discovery or detection, of which the Credit Parties are
        aware, by any Person, of Hazardous Materials on the Mortgaged Properties
        which, in the reasonable good faith judgment of the Credit Parties, is
        likely to result in a Material Adverse Effect.

               (b) The Credit Parties shall retain the exclusive right, at their
option, to compromise, settle or defend, at their expense and with their own
counsel, any Indemnified Liabilities; PROVIDED, HOWEVER, that the Credit Parties
shall provide the Bank with all such copies of documents and pleadings relating
to such Indemnified Liabilities as the Bank may reasonably request; PROVIDED,
FURTHER, that in the case of any action in which any Indemnified Person is a
named party thereto, such counsel retained by the Credit Parties shall be
reasonably acceptable to such Indemnified Person. In the case of any such action
in which an Indemnified Person is a named party thereto, the Credit Parties, at
the request of such Indemnified Person, shall keep such Indemnified Person
apprised of all matters relevant to such action and such Indemnified Person
shall have the full right, at its own expense, to participate, through counsel
or otherwise, in all meetings and proceedings with adverse parties or
governmental authorities (other than any confidential meetings unrelated to
claims against such Indemnified Person); PROVIDED, HOWEVER, that if any of the
Credit Parties give notice in writing to such Indemnified Person that the Credit
Parties do not intend, for whatever reason, to defend any such action, then such
Indemnified Person may prosecute its own defense or response with its own
counsel and the reasonable fees of such counsel shall be at the expense of the
Credit Parties for that portion of the action relating to any Indemnified
Liabilities if: (x) such Indemnified Person shall prosecute such defense or
response diligently and in an appropriate manner and (y) such Indemnified
Person, at the request of any of the Credit Parties, shall keep the Credit
Parties apprised of all matters relevant to such action; PROVIDED, FURTHER, that
in the event that such Indemnified Person does not consent to any settlement or
compromise proposed by the parties to such action and acceptable to the Credit
Parties, then the liability of the Credit Parties under SECTIONS 9.12 and 9.13
of this Agreement for any Indemnified Liabilities shall not exceed that
liability which the Credit Parties would have had if such Indemnified Person had
consented to such settlement or compromise.

               (c) Upon the occurrence of any of the events contemplated by
subsection (a) above relating to any Mortgaged Property, the Bank shall have
(but need not exercise) the right to retain, at its own expense, consultants and
specialists of the Bank's choice to assess the necessity for and appropriateness
of the investigation, removal, remediation, encapsulation or

                                      -66-

other treatment of any Hazardous Materials found on the Mortgaged Properties. If
the Bank reasonably determines that any such activities are necessary and
appropriate to prevent the occurrence of a Material Adverse Effect, it shall
deliver written notice to the Credit Parties of the basis of such determination,
describing such activities with reasonable specificity. Upon receipt of such
notice, and if such activities are required by law, the Credit Parties will
diligently, and in a reasonable manner, undertake and complete such activities
to the Bank's reasonable satisfaction, at the Credit Parties' sole expense.

               (d) The Indemnified Persons shall give prompt written notice to
the Credit Parties of any claim against the Indemnified Persons which might give
rise to a claim by the Indemnified Persons against the Credit Parties under
SECTION 9.12.

               Section 9.14. LIMITATION BY LAW. All rights, remedies and powers
provided in this Agreement and the other Loan Documents may be exercised only to
the extent that the exercise thereof does not violate any applicable provision
of law, and all the provisions of this Agreement and the other Loan Documents
are intended to be subject to all applicable mandatory provisions of law which
may be controlling and to be limited to the extent necessary so that they will
not render this Agreement or any other Loan Document invalid, unenforceable, in
whole or in part, or not entitled to be recorded, registered or filed under the
provisions of any applicable law.

                                                        Senior Vice President

                DESCRIPTION OF CERTAIN COMPENSATORY ARRANGEMENTS

1.   The Company has entered into an arrangement with David Juengel, the
     Company's Vice President-Treasurer, providing for severance payments equal
     to four months salary in the event that Mr. Juengel's employment is
     terminated as a result of a sale of all or part of the Company or otherwise
     without cause. Such severance payments are subject to mitigation by any
     compensation received by Mr. Juengel from other employment. The Company has
     also agreed to consider a bonus payment to Mr. Juengel not to exceed 30% of
     his annual salary in the event that Mr. Juengel assists in the consummation
     prior to January 31, 1997 of certain compensable events including a sale or
     merger of the Company or a sale of its joint venture interests. Any such
     bonus would be recommended in the discretion of the Company's President and
     Chief Executive Officer based on Mr. Juengel's performance and would be
     subject to approval by the Board of Directors.

2.   The Company has entered into a separation arrangement with Michael Loy, the
     Company's Vice President-Chief Financial Officer, providing for the
     termination of his employment by the Company effective October 31, 1996.
     Mr. Loy will be entitled to receive his salary through that date, plus
     severance payments equal to four months salary, accrued vacation and other
     employee benefits, the unvested portion of his outstanding award under the
     Company's 1993 Incentive Compensation Plan due January 31, 1997 and
     Company-paid health benefits through February 28, 1997. Mr. Loy would also
     be eligible for a bonus equal to four months salary in the event that prior
     to his termination Mr. Loy assists in effecting a sale of the Company's
     joint venture interests or all or a majority of the Company that occurs
     prior to January 31, 1997. In the event Mr. Loy voluntarily terminates his
     employment prior to October 31, 1996 he would remain entitled to the
     severance benefits described above but would no longer be eligible for a
     bonus.
