                    FIRST WAVE MARINE, INC. AND SUBSIDIARIES
              NOTES TO UNAUDITED CONSOLIDATED FINANCIAL STATEMENTS
                      (In thousands, except per share data)


Note 1   In the opinion of management the accompanying unaudited consolidated
         financial statements reflect all adjustments necessary to present
         fairly the financial position of First Wave Marine, Inc. ("First Wave"
         or the "Company") as of June 30, 1998, and the results of operations
         for the three and six month periods ended June 30, 1998 and 1997 and
         cash flows for the six month periods ended June 30, 1998 and 1997. All
         such adjustments are of a normal recurring nature. These interim
         financial statements should be read in conjunction with the audited
         financial statements and related notes included in the Company's Annual
         Report on Form 10-K for the year ended December 31, 1997.

Note 2   The consolidated financial statements include the accounts of First
         Wave and its wholly-owned subsidiaries. All material intercompany
         transactions are eliminated in consolidation.

Note 3   The results of operations for the six month period ended June 30,
         1998 are not necessarily indicative of the results to be expected for
         the entire year.

Note 4   11% Senior Notes Offering - On February 2, 1998, the Company
         completed a registered offering of $90,000 aggregate principal amount
         of senior notes. The senior notes bear interest at the rate of 11% per
         annum; principal is due at maturity in February 2008. The senior notes
         are fully and unconditionally guaranteed, jointly and severally, by all
         of the Company's direct and indirect subsidiaries. Each subsidiary
         guarantor is 100% owned by the Company.

         The Company is subject to restrictive covenants under the related trust
         indenture. The indenture contains covenants that, among other things,
         limit the ability of the Company and its subsidiaries to incur
         additional indebtedness, make certain investments, create some types of
         liens, enter into certain transactions with affiliates, sell assets,
         enter into some types of mergers and consolidations, allow subsidiaries
         to create certain dividend and other payment restrictions, enter into
         sale and leaseback transactions, and issue or sell capital stock of
         subsidiaries.

         Separate financial statements and other disclosures concerning the
         subsidiary guarantors are not presented because management has
         determined such financial statements and other disclosures are not
         material to investors. The combined


                                       4

<PAGE>   7

         condensed income statement information for the Company's subsidiary
         guarantors is the same as the Company's. The combined condensed balance
         sheet information of the Company's subsidiary guarantors is as follows:

Note 5   Acquisitions - On February 2, 1998, the Company completed the
         acquisition of all of the outstanding capital stock of John Bludworth
         Marine, a company that owns and operates shipyard facilities in
         Pasadena, Texas and Galveston, Texas. The Company paid $15,000 in cash
         and issued a promissory note in the amount of $4,000. The Company used
         a portion of the proceeds from its $90,000 senior notes offering
         (discussed above) to fund the cash portion of the acquisition. The
         promissory note was adjustable upward or downward based upon
         outstanding debt and a final calculation of earnings before interest,
         taxes, depreciation and amortization of the acquired company. The final
         calculation of the applicable outstanding debt of John Bludworth Marine
         resulted in an increase to the purchase price of approximately $5,157.
         The final calculation of EBITDA resulted in an increase to the purchase
         price of approximately $1,480. The promissory note bore interest at
         8.5% per annum and was payable on or before July 31, 1998.

         On May 27, 1998, $5,157 of the promissory note was paid. The balance of
         the note, approximately $5,500 was paid on July 30, 1998.

         The acquisition has been accounted for as a purchase and the results of
         John Bludworth Marine have been included in the accompanying
         consolidated financial statements since the date of the acquisition.
         The allocation of the purchase price resulted in intangibles, primarily
         goodwill, of approximately $14,081 which is being amortized on a
         straight-line basis over a forty year period.

         On May 15, 1998, the Company completed the acquisition of certain
         assets of the Barge Building Division of Galveston Shipbuilding Company
         ("BBD - GSC"). The Company acquired the fixed assets, including land, a
         contract to build four tank barges and up to five barge covers, and the
         name "Galveston Shipbuilding Company" for $5,500, subject to a final
         purchase price adjustment based upon the performance of the business.
         The acquisition has been accounted for as a purchase and the results of
         BBD - GSC have been included in the accompanying consolidated financial
         statements since the date of the acquisition.

         The following unaudited pro forma consolidated results of operations
         have been prepared as if John Bludworth Marine and BBD-GSC had been
         acquired as of January 1 of fiscal 1998 and 1997. This pro forma
         information is not necessarily indicative of the results of operations
         that would have occurred had the acquisitions been made on those dates
         or of results which may occur in the future.

Note 6   Shareholder Line of Credit - In February 1998, the board of directors
         of the Company approved a maximum $1,000 line of credit available to
         three employee director shareholders of the Company. The line of credit
         allows borrowings of up to $600 to one of the shareholders and up to
         $200 to each of the other two shareholders. Any borrowings under the
         line of credit will bear an interest rate of 6% per annum with interest
         payable annually and principal to be amortized over a ten year period
         through the pro rata reduction of the line of credit commencing March
         2001.

Note 7   Cash and Cash Equivalents - The Company maintains cash and cash
         equivalents with various financial institutions. At times, the balances
         in these accounts could exceed the FDIC insured balance limit of $100
         per bank.

         At June 30, 1998, the Company had $13,555 invested in a money market
         fund. The fund seeks to pay income monthly and to maintain a constant
         value of $1 per share. The fund invests in high quality money market
         instruments which consist primarily of U.S. Treasury obligations,
         obligations issued or guaranteed by U.S. agencies or instrumentalities,
         mortgage-backed securities, commercial paper, bank obligations and
         deposit notes.

Note 8   Investments Available-for-Sale - Included in investments
         available-for-sale at June 30, 1998 is an investment in a mutual fund
         which invests in another portfolio that invests primarily in "loan
         interest" - portions of senior, floating-rate loans made by U.S. banks
         and other financial institutions to large corporate customers. The fund
         seeks to achieve a high level of current income while minimizing
         fluctuations in net asset values. The carrying value and estimated fair
         value of the investment at June 30, 1998 were substantially the same.

Note 9   Investments Held-to-Maturity - As a result of the 11% Senior Notes
         offering, the Company was required to deposit funds into a trust
         account to pay the first and second semi-annual interest payments on
         the notes. As a result, two securities were purchased with maturity
         dates as near as possible to the interest payment dates. A Fannie Mae
         Discount Note with a maturity date of July 27, 1998 was purchased for
         approximately $4,824 to cover the August 1, 1998 interest payment. A
         U.S. Treasury Bill with a maturity date of January 7, 1999 was
         purchased for approximately $4,718 to cover the February 1, 1999
         interest payment. At maturity, the value of both securities will
         approximate the amount of the semi-annual interest payment, which is
         $4,950. The approximate fair value of the above two securities at June
         30, 1998 was $9,748.

         Also included in "Investments held-to-maturity" are a certificate of
         deposit with a financial institution in the amount of $1,000 with a
         maturity date of February 4, 1999, and another certificate of deposit
         with another financial institution in the amount of $250 with a
         maturity date of February 3, 1999. The balances of both certificates of
         deposit exceed the FDIC insured balance limit of $100 per bank.

Note 10  Line of Credit - On June 9, 1998, the Company entered into a credit
         agreement to obtain a $10,000 revolving line of credit facility with a
         financial institution. The facility is collateralized by accounts
         receivable. Borrowings on the line of credit bear interest at the Wall
         Street Journal Prime Rate plus one-half percent. There were no
         borrowings outstanding on the line of credit at June 30, 1998.

ITEM 2.  MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND 
         RESULTS OF OPERATIONS

         All statements other than statements of historical fact contained in
         this Form 10-Q, including statements in this "Management's Discussion
         and Analysis of Financial Condition and Results of Operations"
         concerning results of operations, results from proposed shipyard
         acquisitions, future expansion plans and other matters are
         forward-looking statements. Forward-looking statements in this Form
         10-Q generally are accompanied by words such as "anticipate,"
         "believe," estimate" or "expect" or similar statements. Although the
         Company believes that the expectations reflected in such
         forward-looking statements are reasonable, no assurance can be given
         that such expectations will prove correct. Factors that could cause the
         Company's results to differ materially from the results discussed in
         such forward-looking statements include risks such as the dependence on
         the oil and gas industry, difficulties related to managing growth in
         operations, dependence on significant customers, competition, the risks
         associated with contractual pricing, the success of the recent
         expansion into the offshore drilling rig segment, and labor, operating,
         regulatory and other risks in the shipbuilding industry as well as
         risks relating to the capital expenditure budgets of the Company's
         customers in the offshore support vessel, offshore barge and inland
         marine industries. All forward-looking statements in this Form 10-Q are
         expressly qualified in their entirety by the cautionary statements in
         this paragraph.

         The following discussion of the Company's financial condition, results
         of operations, liquidity and capital resources should be read in
         conjunction with the Company's Consolidated Financial Statements and
         the Notes to the Consolidated Financial Statements included elsewhere
         in this report.

         GENERAL

         The Company's business is primarily derived from providing repair and
         upgrade services to inland and offshore marine vessels, including
         barges, boats, drilling rigs and ships. To a lesser extent the Company
         engages in new construction of such inland and offshore marine vessels.
         The Company believes the demand for repair and upgrade services is
         significantly more stable than the demand for new construction. While
         trends in oil and natural gas prices can affect the demand for offshore
         support vessels and drilling rigs, the Company anticipates its demand
         will remain strong for repair activity even with a short-term downturn
         in oil and gas prices. While any prolonged depression in oil and
         natural gas prices could have an adverse effect on the Company's
         results of operations if a significant number of offshore support
         vessels and drilling rigs were taken out of active service in the Gulf
         of Mexico, the declines in oil and gas prices in 1998 have not affected
         the Company's operations to date.


                                       8

         The Company currently operates three shipyards in the Houston, Texas
         area (Brady Island, Greens Bayou and Pasadena) and three in the
         Galveston, Texas area (East Pelican Island, West Pelican Island and
         Galveston Island). The Company acquired the Pasadena and West Pelican
         Island shipyards on February 2, 1998, and the Galveston Island shipyard
         on May 15, 1998. The Company currently employs approximately 1,000
         production workers at its six shipyards.

         The Company also provides related environmental services, including
         cleaning, degassing and wastewater treatment. Although this business
         comprises a small percentage of the Company's total revenues, it
         generates high margins and enhances the Company's strategy to be the
         only one-stop source of all shipyard services for all segments of the
         offshore and inland marine markets in Texas.

         RECENT DEVELOPMENTS

         On May 15, 1998, the Company acquired its Galveston Island shipyard
         with its completion of the acquisition of certain assets of the Barge
         Building Division of Galveston Shipbuilding Company ("BBD - GSC"). The
         Company acquired the fixed assets, including land, a contract to build
         four tank barges and up to five barge covers, and the name "Galveston
         Shipbuilding Company" for $5.5 million, subject to a final purchase
         price adjustment based upon the performance of the business. The
         acquisition has been accounted for as a purchase and the results of BBD
         - GSC have been included in the accompanying consolidated financial
         statements since the date of acquisition.

         Simultaneously with closing the senior notes offering, the Company
         completed the acquisition of all of the outstanding shares of John
         Bludworth Marine, Inc. ("John Bludworth Marine"). The John Bludworth
         Marine acquisition provided the Company with the Pasadena facility near
         Houston, Texas and the West Pelican Island facility in Galveston,
         Texas. The Company paid $15.0 million in cash and issued a promissory
         note in the amount of $4.0 million. The promissory note was adjustable
         upward or downward based upon outstanding debt and a final calculation
         of earnings before interest, taxes, depreciation and amortization
         ("EBITDA") of the acquired company. The final calculation of the
         applicable outstanding debt of John Bludworth Marine resulted in an
         increase to the purchase price of approximately $5.2 million. The final
         calculation of EBITDA resulted in an increase to the purchase price of
         approximately $1.5 million. The promissory note as adjusted for
         outstanding debt and EBITDA bore interest at 8.5% per annum and was
         payable on or before July 31, 1998. On May 27, 1998, the Company paid
         approximately $5.2 million of the promissory note. The Company made the
         final payment on the balance of the note, approximately $5.5 million,
         on July 30, 1998.

         RESULTS OF OPERATIONS

         Comparison of the three months ended June 30, 1998 to the three months
         ended June 30, 1997.

         Revenues increased 167% to $21.3 million in the 1998 period, compared
         with $8.0 million in the 1997 period, primarily due to five additional
         shipyards in operation during the 1998 period as compared to only one
         shipyard in operation during the 1997 period. The Greens Bayou facility
         began operations in the third quarter of 1997. The East Pelican Island
         facility, a start-up, began generating revenues in the first quarter of
         1998. As discussed above, the Pasadena and West Pelican Island
         facilities were acquired on February 2, 1998. The Galveston Island
         facility was acquired on May 15, 1998 as a result of the BBD-GSC
         acquisition. Only the results of operation of BBD-GSC subsequent to the
         date of acquisition are included in the results of operations of the
         Company for the three month period ended June 30, 1998.

         Cost of revenues rose 226% to $13.7 million in the 1998 period from
         $4.2 million in the 1997 period, primarily due to the additional
         shipyards in operation during the 1998 period.

         Gross profit increased 101% to $7.6 million in the 1998 period from
         $3.8 million in the 1997 period due to the additional shipyards in
         operation during the 1998 period. The gross profit margin decreased to
         36% in the 1998 period from 47% in the 1997 period, primarily due to
         the start-up nature of the East Pelican Island shipyard, and the
         decrease in higher margin environmental services revenue as a
         percentage of total revenue.

         General and administrative expenses increased 276% to $3.7 million in
         the 1998 period from $1.0 million in the 1997 period. General and
         administrative expenses as a percentage of revenues for the 1998 period
         represented 17% of total revenues, as compared to 12% for the 1997
         period. The increase in general and administrative expenses as a
         percentage of revenues is primarily due to the full staffing and
         certain overhead expenses incurred at the start-up of the Company's
         East Pelican Island operations in advance of revenue generation.

         Net interest expense rose to $2.3 million in the 1998 period from
         $424,000 in the 1997 period due to three months of interest expense on
         the $90 million 11% Senior Notes reflected in the 1998 period.

         The elimination of minority interest in the 1998 period from
         approximately $237,000 in the 1997 period is due to all minority
         shareholders of this subsidiary exchanging their shares for shares in
         First Wave effective December 31, 1997. As a result, First Wave has
         owned 100% of the common stock of all of its subsidiaries for the
         entire 1998 period. 


                                       10

<PAGE>   13

         The decrease in income tax expense from approximately $871,000 in the
         1997 period to $646,000 in the 1998 period is directly attributable to
         the decrease in income before income taxes and extraordinary item.

         The decrease in net earnings from the 1997 period to the 1998 period is
         due primarily to the following: the additional interest expense related
         to the $90 million senior notes, and the increase in general and
         administrative expenses related to the start-up of the Company's East
         Pelican Island shipyard during the 1998 period.

         Comparison of the six months ended June 30, 1998 to the six months
         ended June 30, 1997.

         Revenues increased 119% to $37.1 million in the 1998 period, compared
         with $16.9 million in the 1997 period, primarily due to five additional
         shipyards in operation during the 1998 period as compared to only one
         shipyard in operation during the 1997 period. The Greens Bayou facility
         began operations in the third quarter of 1997. The East Pelican Island
         facility, a start-up, began generating revenues in the first quarter of
         1998. As discussed above, the Pasadena and West Pelican Island
         facilities were acquired on February 2, 1998 as a result of the John
         Bludworth Marine acquisition. The Galveston Island facility was
         acquired on May 15, 1998 as a result of the BBD-GSC acquisition. Only
         the results of operation of John Bludworth Marine and BBD-GSC
         subsequent to the date of acquisition are included in the results of
         operations of the Company for the six month period ended June 30, 1998.

         Cost of revenues rose 152% to $23.9 million in the 1998 period from
         $9.5 million in the 1997 period, primarily due to the additional
         shipyards in operation during the 1998 period.

         Gross profit increased 77% to $13.2 million in the 1998 period from
         $7.4 million in the 1997 period due to the additional shipyards in
         operation during the 1998 period. The gross profit margin decreased to
         36% in the 1998 period from 44% in the 1997 period, primarily due to
         the expenses incurred as a result of the start-up nature of the East
         Pelican Island shipyard, and the decrease in higher margin
         environmental services revenue as a percentage of total revenue.

         General and administrative expenses increased 165% to $7.4 million in
         the 1998 period from $2.8 million in the 1997 period. General and
         administrative expenses as a percentage of revenues for the 1998 period
         represented 20% of total revenues, as compared to 17% for the 1997
         period. The increase in general and administrative expenses as a
         percentage of revenues is primarily due to the full staffing and
         certain overhead expenses incurred at the start-up operations in
         advance of revenue generation.


                                       11

<PAGE>   14

         Net interest expense rose to $4.1 million in the 1998 period from
         $842,000 in the 1997 period due to five months of interest expense on
         the $90 million 11% Senior Notes reflected in the 1998 period.

         The elimination of minority interest in the 1998 period from
         approximately $403,000 in the 1997 period is due to all minority
         shareholders of this subsidiary exchanging their shares for shares in
         First Wave effective December 31, 1997. As a result, First Wave has
         owned 100% of the common stock of all of its subsidiaries for the
         entire 1998 period.

         The decrease in income tax expense from approximately $1.4 million in
         the 1997 period to $729,000 in the 1998 period is directly attributable
         to the decrease in income before income taxes and the extraordinary
         item.

         The extraordinary item reflected in the 1998 period of approximately
         $933,000 relates to approximately $1.5 million in loss on
         extinguishment of debt, net of income tax benefit of approximately
         $559,000.

         The decrease in net earnings from the 1997 period to the 1998 period is
         due primarily to the following: the loss on the extinguishment of debt,
         the additional interest expense related to the $90 million senior
         notes, and the increase in general and administrative expenses incurred
         in connection with the start-up of the East Pelican Island shipyard
         during the 1998 period.

         INFLATION AND CHANGING PRICES

         The Company does not believe that general price inflation has had a
         significant impact on the Company's results of operations during the
         periods presented. To the extent that the effects of inflation are not
         offset by improvements in manufacturing and purchasing efficiency and
         labor productivity, the Company generally has been able to take such
         effects into account in pricing its contracts with customers. There can
         be no assurance, however, that inflation will not have a material
         effect on the Company's business in the future.

         LIQUIDITY AND CAPITAL RESOURCES

         The Company's ongoing liquidity requirements arise primarily from its
         need to service debt, fund working capital, acquire additional shipyard
         facilities and make capital improvements to its facilities. Prior to
         the Company's senior notes offering discussed below, bank financing and
         internally generated funds provided funding for these activities.

         The Company completed its $90 million 11% Senior Notes offering on
         February 2, 1998. Simultaneous with the senior notes offering, the
         Company used $15.0 million of the net proceeds of the offering to
         complete the John Bludworth Marine 

                                       12

         acquisition. As a provision of the senior notes offering, the Company
         was required to deposit sufficient funds in a trust account to cover
         the first two semi-annual interest payments on the senior notes. The
         expenses incurred by the Company in connection with the senior notes
         offering were approximately $4.4 million. Subsequent to the senior
         notes offering and the John Bludworth Marine acquisition, approximately
         $25.2 million was used to repay indebtedness of the Company. On May 15,
         1998, $5.5 million of the net proceeds of the offering was used to
         complete the BBD-GSC acquisition.

         Excluding the acquisition of the Pasadena facility, the West Pelican
         Island facility and the Galveston Island facility, the Company has used
         approximately $11.6 million of proceeds from the senior notes offering
         on capital expenditures during the six month period ended June 30,
         1998. The Company has budgeted $20 to $22 million of capital
         expenditures for the remainder of 1998.

         During the current quarter of 1998, the Company used a portion of the
         remaining net proceeds of the offering discussed above as follows: $5.5
         million was used to complete the BBD- GSC acquisition and $5.2 million
         was used to paydown the promissory note to the former owner of John
         Bludworth Marine. On July 30, 1998, $5.5 million was used to pay the
         balance of the note to the former owner of John Bludworth Marine.

         Under its indenture entered into in connection with the senior notes
         offering, the Company is permitted to borrow up to the greater of $20
         million or 85% of its accounts receivable. On June 9, 1998, the Company
         obtained a $10.0 million revolving line of credit collateralized by
         accounts receivable. Additionally, the Company has $4.0 million in
         borrowing capacity under another revolving line of credit. There were
         no borrowings outstanding on any of the lines of credit at June 30,
         1998.

         Net cash provided by operating activities for the six month periods
         ended June 30, 1998 and 1997 was $3.2 million and $1.9 million,
         respectively.

         Net cash used in investing activities was $43.9 million and $300,000
         for the six month periods ended June 30, 1998 and 1997, respectively.
         During the 1998 period, cash used in investing activities was for the
         completion of the John Bludworth Marine and BBD-GSC acquisitions,
         capital improvements and the purchase of investments.

         Net cash provided by (used in) financing activities was $57.6 million
         and ($1.3) million for the six month periods ended June 30, 1998 and
         1997, respectively. Cash provided by financing activities resulted from
         the completion of the $90 million 11% Senior Notes offering during the
         period. Cash generated from the 11% Senior Notes offering was used to
         prepay indebtedness of the Company and pay the remainder of the
         financing costs related to the 11% Senior Notes offering.


                                       13

         Management believes that with the remaining proceeds from the 11%
         Senior Notes offering, cash generated from operations, and, if
         necessary, borrowings under the Company's lines of credit, the Company
         will have sufficient resources available to meet its anticipated
         requirements for capital expenditures and working capital needs through
         the remainder of fiscal year 1998.

         YEAR 2000 COMPUTER ISSUE

         Many computer systems in use today were designed and developed using
         two digits, rather than four, to specify the year. As a result, such
         systems will recognize the year 2000 as "00". This could cause many
         computer applications to fail completely or to create erroneous results
         unless corrective measures are taken.

         The Company currently believes that with recent upgrades made to its
         existing software, the Year 2000 problem will not pose significant
         operations problems for the Company's computer systems. The Company has
         initiated discussions with its significant suppliers, large customers,
         financial institutions and utilities to assure that those parties have
         appropriate plans to remediate Year 2000 issues.

Restricted Subsidiary or that is accounted for by the equity method of
accounting shall be included only to the extent of the amount of dividends or
distributions paid in cash to the specified Person as to which Consolidated Net
Income is being calculated, (ii) the Net Income of any Restricted Subsidiary
shall be excluded to the extent that the declaration or payment of dividends or
similar distributions by such Restricted Subsidiary

distributions, unless such dividends or other distributions may be declared and

payment, but only to the extent of any cash received by such Person upon
issuance of such preferred equity, less (x) all write-ups (other than write-ups

                                    THE NOTES

SECTION 2.1.    FORM AND DATING.

         (a) General Form of Notes. The Notes and the Trustee's certificate of
authentication shall be substantially in the form of Exhibit A hereto, which
Exhibit is part of this Indenture. The Notes may have notations, legends or
endorsements required by law, stock exchange rule or usage. Each Note shall be
dated the date of its authentication. The Notes shall be issued only in
registered form without coupons and only in minimum denominations of $1,000 and
integral multiples thereof. The terms and provisions contained in the Notes
shall constitute, and are hereby expressly made, a part of this Indenture and
the Company and the Trustee, by their execution and delivery of this Indenture,
expressly agree to such terms and provisions and to be bound thereby. The Notes
shall be issued initially in the form of a permanent, global note in definitive,
fully registered form, without coupons, substantially in the form of Exhibit A
hereto (including the text and schedule called for by footnotes 1 and 2 thereto)
(the "Global Note"). Upon issuance, such Global Note shall be duly executed by
the Company and authenticated by the Trustee as hereinafter provided and
deposited with the Trustee as custodian for the Depositary. Any Certificated
Note that may be issued pursuant to Section 2.06(a) hereof, shall be issued in
the form of a note in definitive, fully registered form, without coupons,
substantially in the form set forth in Exhibit A hereto (excluding the text and
schedule 


                                       17


<PAGE>   25

called for by footnotes 1 and 2 thereto). Upon issuance, any such Certificated
Note shall be duly executed by the Company and authenticated by the Trustee as
hereinafter provided.

         (b) Form of Global Notes. Each Global Note (i) shall represent such
portion of the outstanding Notes as shall be specified therein, (ii) shall
provide that it shall represent the aggregate amount of outstanding Notes from
time to time endorsed thereon and that the aggregate amount of outstanding Notes
represented thereby may from time to time be reduced or increased, as
appropriate, to reflect exchanges and redemptions, (iii) shall be registered in
the name of the Depositary or its nominee, duly executed by the Company and
authenticated by the Trustee as provided herein, for credit to the respective
accounts of the Holders (or such accounts as they may direct) at the Depositary,
(iv) shall be delivered by the Trustee or its Agent to the Depositary or a Note
Custodian pursuant to the Depositary's instructions and (v) shall bear a legend
substantially to the following effect:

         "Unless this certificate is presented by an authorized representative
of The Depository Trust Company, a New York corporation ("DTC"), New York, New
York, to the Company or its agent for registration of transfer, exchange or
payment, and any certificate issued is registered in the name of Cede & Co. or
such other name as is required by an authorized representative of DTC (and any
payment hereon is made to Cede & Co. or to such other entity as is requested by
an authorized representative of DTC), ANY TRANSFER, PLEDGE OR OTHER USE HEREOF
FOR VALUE OR OTHERWISE BY OR TO ANY PERSON IS WRONGFUL inasmuch as the
registered owner hereof, Cede & Co., has an interest herein."

Members of, or participants in, the Depositary ("DTC Participants") shall have
no rights under this Indenture with respect to any Global Note held on their
behalf by the Depositary, and the Depositary may be treated by the Company, the
Trustee, and any agent of the Company or the Trustee as the absolute owner of
such Global Note for all purposes whatsoever. Notwithstanding the foregoing,
nothing herein shall prevent the Company, the Trustee, or any agent of the
Company or the Trustee from giving effect to any written certification, proxy or
other authorization furnished to the Depositary or impair, as between the
Depositary and its agent members, the operation of customary practices governing
the exercise of the rights of a Holder of any Note.

         Whenever, as a result of an optional redemption of Notes by the
Company, a Change of Control Offer, an Asset Sale Offer or an exchange pursuant
to the second sentence of Section 2.06(a) hereof, a Global Note is redeemed,
repurchased or exchanged in part, such Global Note shall be surrendered by the
Holder thereof to the Trustee who shall cause an adjustment to be made to
Schedule A thereof so that the principal amount of such Global Note will be
equal to the portion of such Global Note not redeemed, repurchased or exchanged
and shall thereafter return such Global Note to such Holder, provided that any
such Global Note shall be in a principal amount of $1,000 or an integral
multiple thereof.

         (c) Form of Certificated Notes. Certificated Notes may be produced in
any manner determined by the Officers of the Company executing such Notes, as
evidenced by their 


                                       18
<PAGE>   26

execution of such Notes. The Trustee must register Certificated Notes so issued
in the name of, and cause the same to be delivered to, such Person (or its
nominee). Except as provided in Section 2.6, any Person having a beneficial
interest in the Global Note may not exchange such beneficial interest for fully
Certificated Notes in duly registered form.

         (d) Provisions Applicable to Forms of Notes. The Notes may also have
such additional provisions, omissions, variations or substitutions as are not
inconsistent with the provisions of this Indenture, and may have such letters,
numbers or other marks of identification and such legends or endorsements placed
thereon as may be required to comply with this Indenture, any Applicable Law or
with any rules made pursuant thereto or with the rules of any securities
exchange or governmental agency or as may be determined consistently herewith by
the Officers of the Company executing such Notes, as conclusively evidenced by
their execution of such Notes. All Notes shall be otherwise substantially
identical except as provided herein.

         Subject to the provisions of this Article 2, a registered Holder of a
beneficial interest in a Global Note may grant proxies and otherwise authorize
any Person to take any action that a Holder is entitled to take under this
Indenture or the Notes.

SECTION 2.2.    EXECUTION AND AUTHENTICATION.

         An Officer of the Company shall sign the Notes for the Company by
manual or facsimile signature. The Company's seal may be reproduced on the Notes
and may be in facsimile form.

         If an Officer of the Company whose signature is on a Note no longer
holds that office at the time a Note is authenticated, the Note shall
nevertheless be valid.

         A Note shall not be valid or obligatory for any purpose or entitled to
the benefits of this Indenture until authenticated by the manual signature of
the Trustee or its authenticating agent. The signature shall be conclusive
evidence that the Note has been authenticated under this Indenture.

         The Trustee shall, upon the delivery to the Trustee of a written order
of the Company signed by two Officers, from time to time, authenticate Notes for
original issue up to an aggregate principal amount of $90,000,000. The aggregate
principal amount of Notes outstanding at any time may not exceed such amount
except as provided in Section 2.7 hereof.

         The Trustee may appoint an authenticating agent to authenticate Notes.
An authenticating agent may authenticate Notes whenever the Trustee may do so.
Each reference in this Indenture to authentication by the Trustee includes
authentication by such agent. An authenticating agent has the same rights as an
Agent to deal with the Company or an Affiliate of the Company.

<PAGE>   27

SECTION 2.3.    TRUSTEE, REGISTRAR AND PAYING AGENT.

         The Company shall maintain an office or agency where Notes may be
presented for registration of transfer or for exchange ("Registrar") and an
office or agency where Notes may be presented for payment ("Paying Agent"). The
Registrar shall keep a register ("Register") of the Notes and of their transfer
and exchange. The Company may also from time to time appoint one or more
co-registrars and one or more additional paying agents. The term "Registrar"
includes any co-registrar and the term "Paying Agent" includes any additional
paying agent. The Company may change any Paying Agent or Registrar upon notice
to the Holders. The Company shall notify the Trustee in writing of the name and
address of any Agent not a party to this Indenture. If the Company fails to
appoint or maintain another entity as Registrar or Paying Agent, the Trustee
shall act, subject to the last paragraph of this Section 2.3, as such. The
Company or any of its Subsidiaries may act as Paying Agent or Registrar;
provided, however, that none of the Company, its Subsidiaries or the Affiliates
of the foregoing shall act (i) as Paying Agent in connection with any
redemption, offer to purchase, discharge or defeasance, as otherwise specified
in this Indenture, and (ii) as Paying Agent or Registrar if a Default or Event
of Default has occurred and is continuing.

         The Company hereby appoints Bank One, N.A., at its Corporate Trust
Office, as the Trustee hereunder and Bank One, N.A., hereby accepts such
appointment. The Trustee shall have the powers and authority granted to and
conferred upon it in the Notes and hereby and such further powers and authority
to act on behalf of the Company as may be mutually agreed upon by the Company
and the Trustee, and the Trustee shall keep a copy of this Indenture available
for inspection during normal business hours at its Corporate Trust Office.

         The Company initially appoints DTC to act as Depositary with respect to
the Global Notes.

         The Company initially appoints the Trustee to act as the Registrar and
Paying Agent and to act as Note Custodian with respect to the Global Notes.

         All of the terms and provisions with respect to such powers and
authority contained in the Notes are subject to and governed by the terms and
provisions hereof.

         The Trustee may resign as Registrar or Paying Agent upon 30 days prior
written notice to the Company.

SECTION 2.4.    PAYING AGENT TO HOLD MONEY IN TRUST.

         The Company shall require each Paying Agent other than the Trustee to
agree in writing that the Paying Agent will hold in trust for the benefit of the
Holders and the Trustee all money held by the Paying Agent for the payment of
principal of, premium, if any, and interest on the Notes, and shall notify the
Trustee of any default by the Company in making any such payment. While any such
default continues, the Trustee may require a Paying Agent to 


                                       20
<PAGE>   28

pay all money held by it to the Trustee. The Company at any time may require a
Paying Agent to pay all money held by it to the Trustee. Upon payment of all
such money over to the Trustee, the Paying Agent (if other than the Company or a
Subsidiary) shall have no further liability for the money. If the Company or a
Subsidiary acts as Paying Agent, it shall segregate and hold in a separate trust
fund for the benefit of the Holders all money held by it as Paying Agent. Upon
any bankruptcy or reorganization proceedings relating to the Company, the
Trustee shall serve as Paying Agent for the Notes.

SECTION 2.5.    HOLDER LISTS.

         The Trustee shall preserve in as current a form as is reasonably
practicable to it the most recent list available to it of the names and
addresses of all Holders and shall otherwise strictly comply with TIA Section
312(a). If the Trustee is not the Registrar, the Company shall furnish to the
Trustee at least ten Business Days before each Interest Payment Date and at such
other times as the Trustee may request in writing, a list in such form and as of
such date as the Trustee may require of the names and addresses of the Holders
of Notes and the Company shall otherwise strictly comply with TIA Section 
312(a).

SECTION 2.6.    TRANSFER AND EXCHANGE.

         (a) The Global Note shall be exchanged by the Company for one or more
Certificated Notes if (a) the Depositary (i) has notified the Company that it is
unwilling or unable to continue as, or ceases to be, a clearing agency
registered under Section 17A of the Exchange Act and (ii) a successor to the
Depositary registered as a clearing agency under Section 17A of the Exchange Act
is not able to be appointed by the Company within 90 calendar days or (b) the
Depositary is at any time unwilling or unable to continue as Depositary and a
successor to the Depositary is not able to be appointed by the Company within 90
calendar days. If an Event of Default occurs and is continuing, the Company
shall, at the request of the Holder thereof, exchange all or part of the Global
Note for one or more Certificated Notes; provided that the principal amount of
each of such Certificated Notes and such Global Note, after such exchange, shall
be $1,000 or an integral multiple thereof. In addition, the Holder of a
beneficial interest in the Global Note may at any time exchange such interest
for a Certificated Note in a principal amount of $1,000 or an integral multiple
thereof. Whenever a Global Note is exchanged as a whole for one or more
Certificated Notes, such Global Note shall be surrendered by the Holder thereof
to the Trustee for cancellation. Whenever a Global Note is exchanged in part for
one or more Certificated Notes pursuant to this Section 2.06(a), it shall be
surrendered by the Holder thereof to the Trustee and the Trustee shall make the
appropriate notations thereon pursuant to Section 2.1(b) hereof. All
Certificated Notes issued in exchange for a Global Note or any portion thereof
shall be registered in such names, and delivered, as the Depositary shall
instruct the Trustee.

         (b) A Holder may transfer a Note only upon the surrender of such Note
for registration of transfer. No such transfer shall be effected until, and the
transferee shall succeed to the rights of a Holder only upon, final acceptance
and registration of the transfer in the 


                                       21
<PAGE>   29

Register by the Registrar. When Notes are presented to the Registrar with a
request to register the transfer of, or to exchange, such Notes, the Registrar
shall register the transfer or make such exchange as requested if its
requirements for such transactions and any applicable requirements hereunder are
satisfied. To permit registrations of transfers and exchanges, the Company shall
execute and the Trustee shall authenticate Certificated Notes at the Registrar's
request.

         (c) The Company shall not be required to make and the Registrar need
not register transfers or exchanges of Certificated Notes (i) selected for
redemption (except, in the case of Certificated Notes to be redeemed in part,
the portion thereof not to be redeemed) and (ii) for a period of 15 calendar
days before a selection of Notes to be redeemed.

         (d) No service charge shall be made for any registration of transfer or
exchange of Notes, but the Company may require payment by Holders of a sum
sufficient to cover any tax or other governmental charge that may be imposed in
connection with any registration of transfer of Notes.

         (e) All Notes issued upon any registration of transfer or exchange
pursuant to the terms of this Indenture will evidence the same debt and will be
entitled to the same benefits under this Indenture as the Notes surrendered for
such registration of transfer or exchange.

         (f) Any Holder of a Global Note shall, by acceptance of such Global
Note, agree that transfers of beneficial interests in such Global Note may be
effected only through a book entry system maintained by such Holder (or its
agent), and that ownership of a beneficial interest in the Notes represented
thereby shall be required to be reflected in book entry form. Transfers of a
Global Note shall be limited to transfers in whole and not in part, to the
Depositary, its successors, and their respective nominees. Interests of
beneficial owners in a Global Note shall be transferred in accordance with the
rules and procedures of the Depositary (or its successors).

SECTION 2.7.    REPLACEMENT NOTES.

         If any mutilated Note is surrendered to the Trustee, or the Company and
the Trustee receive evidence to their satisfaction of the destruction, loss or
theft of any Note, the Company shall, upon the written request of the Holder
thereof, issue and the Trustee, upon the written order of the Company signed by
two Officers of the Company, shall authenticate a replacement Note if the
Trustee's requirements are met. If required by the Trustee or the Company, an
indemnity bond must be supplied by such Holder that is sufficient in the
judgment of the Trustee and the Company to protect the Company, the Trustee, any
Agent and any authenticating agent from any loss that any of them may suffer if
a Note is replaced. The Company may charge for its expenses in replacing a Note.



                                       22
<PAGE>   30

         Every replacement Note is an additional obligation of the Company and
shall be entitled to all of the benefits of this Indenture equally and
proportionately with all other Notes duly issued hereunder.

         The provisions of this Section 2.7 are exclusive and shall preclude (to
the extent lawful) all other rights and remedies with respect to the replacement
or payment of mutilated, destroyed, lost or stolen Notes.

SECTION 2.8.    OUTSTANDING NOTES.

         The Notes outstanding at any time are all the Notes authenticated by
the Trustee except for those canceled by it (or its agent), those delivered to
it (or its agent) for cancellation, those reductions in the interest in a Global
Note effected by the Trustee in accordance with the provisions hereof, and those
described in this Section as not outstanding. Except as set forth in Section 2.9
hereof, a Note does not cease to be outstanding because the Company or an
Affiliate of the Company holds the Note.

         If a Note is replaced pursuant to Section 2.7 hereof, it ceases to be
outstanding unless the Trustee receives proof satisfactory to it that the
replaced Note (other than a mutilated Note surrendered for replacement) is held
by a bona fide purchaser (as such term is defined in Section 8-302 of the
Uniform Commercial Code as in effect in the State of New York).

         If the principal amount of any Note is considered paid under Section
4.1 hereof, it ceases to be outstanding and interest on it ceases to accrue.

         If the Paying Agent (other than the Company, a Subsidiary or an
Affiliate of any thereof) holds, on a redemption date or maturity date, money
sufficient to pay Notes payable on that date, then on and after that date such
Notes shall be deemed to be no longer outstanding and shall cease to accrue
interest.

SECTION 2.9.    TREASURY NOTES.

         In determining whether the Holders of the required principal amount of
Notes have concurred in any direction, waiver or consent, Notes owned by the
Company, or by any Person directly or indirectly controlling or controlled by or
under direct or indirect common control with the Company, shall be considered as
though not outstanding, except that for the purposes of determining whether the
Trustee shall be protected in relying on any such direction, waiver or consent,
only Notes that a Responsible Officer of the Trustee has actual knowledge are so
owned shall be so disregarded.

SECTION 2.10.     TEMPORARY NOTES.

         Until definitive Notes are ready for delivery, the Company may prepare
and the Trustee shall authenticate temporary Notes upon a written order of the
Company signed by two 


                                       23
<PAGE>   31

Officers of the Company. Temporary Notes shall be substantially in the form of
definitive Notes but may have variations that the Company considers appropriate
for temporary Notes and as shall be reasonably acceptable to the Trustee.
Without unreasonable delay, the Company shall prepare and the Trustee shall
authenticate definitive Notes in exchange for temporary Notes.

         Until such exchange, Holders of temporary Notes shall be entitled to
all of the benefits of this Indenture.

SECTION 2.11.     CANCELLATION.

         The Company at any time may deliver Notes to the Trustee or its Agent
for cancellation. The Registrar and Paying Agent shall forward to the Trustee
any Notes surrendered to them for registration of transfer, exchange or payment.
The Trustee (or its Agent) and no one else shall cancel all Notes surrendered
for registration of transfer, exchange, payment, replacement or cancellation and
shall destroy canceled Notes (subject to the record retention requirement of the
Exchange Act). Certification of the destruction of all canceled Notes shall be
delivered to the Company from time to time. The Company may not issue new Notes
to replace Notes that it has paid or that have been delivered to the Trustee (or
its Agent) for cancellation. If the Company acquires any of the Notes, such
acquisition shall not operate as a redemption or satisfaction of the
indebtedness represented by such Notes unless and until the same are surrendered
to the Trustee (or its Agent) for cancellation pursuant to this Section 2.11.

SECTION 2.12.     DEFAULTED INTEREST.

         If the Company defaults in a payment of interest on the Notes, it shall
pay the defaulted interest in any lawful manner plus, to the extent lawful,
interest payable on the defaulted interest, to the Persons who are Holders on a
subsequent special record date, in each case at the rate provided in the Notes
and in Section 4.1 hereof. The Company shall notify the Trustee in writing of
the amount of defaulted interest proposed to be paid on each Note and the date
of the proposed payment. The Company shall fix or cause to be fixed each such
special record date and payment date, provided that no such special record date
shall be less than 10 days prior to the related payment date for such defaulted
interest. At least 15 days before the special record date, the Company (or, upon
the written request of the Company, the Trustee in the name and at the expense
of the Company) shall mail or cause to be mailed to Holders a notice that states
the special record date, the related payment date and the amount of such
defaulted interest to be paid.

SECTION 2.13.     PERSONS DEEMED OWNERS.

         Prior to due presentment for the registration of a transfer of any
Note, the Trustee, any Agent, the Company and any agent of the foregoing shall
deem and treat the Person in whose name any Note is registered as the absolute
owner of such Note for all purposes (including the purpose of receiving payment
of principal of and interest on such Notes; provided 


                                       24
<PAGE>   32

that defaulted interest shall be paid as set forth in Section 2.12), and none of
the Trustee, any Agent, the Company or any agent of the foregoing shall be
affected by notice to the contrary.

SECTION 2.14.     CUSIP NUMBERS

         Pursuant to a recommendation promulgated by the Committee on Uniform
Security Identification Procedures, the Company will print CUSIP numbers on the
Notes, and the Trustee may use CUSIP numbers in notices of redemption and
purchase as a convenience to Holders; provided, however, that any such notices
may state that no representation is made as to the correctness of such numbers
as printed on the Notes and that reliance may be placed only on the other
identification numbers printed on the Notes, and any such redemption or purchase
shall not be affected by any defect or omission in such numbers.


                                    ARTICLE 3

                            REDEMPTION AND PREPAYMENT

SECTION 3.1.    NOTICES TO TRUSTEE.

         If the Company elects to redeem Notes pursuant to the optional
redemption provisions of Section 3.7 hereof, it shall furnish to the Trustee, at
least 30 days but not more than 60 days before a redemption date (unless a
shorter period is acceptable to the Trustee), an Officers' Certificate setting
forth (i) the clause of Section 3.7 pursuant to which the redemption shall
occur, (ii) the redemption date, (iii) the principal amount of Notes to be
redeemed, (iv) the redemption price and accrued and unpaid interest and (v)
whether it requests the Trustee to give notice of such redemption. Any such
notice may be canceled at any time prior to the mailing of notice of such
redemption to any Holder and shall thereby be void and of no effect.

SECTION 3.2.    SELECTION OF NOTES TO BE REDEEMED.

         If less than all of the Notes are to be redeemed at any time, the
Trustee shall select the Notes to be redeemed among the Holders of the Notes in
compliance with the requirements of the principal national securities exchange,
if any, on which the Notes are listed, or, if the Notes are not so listed, on a
pro rata basis, by lot or by such other method as the Trustee shall deem fair
and appropriate; provided that no Notes of $1,000 principal amount or less shall
be redeemed in part. In the event of partial redemption by lot, the particular
Notes to be redeemed shall be selected, unless otherwise provided herein, not
less than 30 nor more than 60 days prior to the redemption date by the Trustee
from the outstanding Notes not previously called for redemption.

         The Trustee shall promptly notify the Company in writing of the Notes
selected for redemption and, in the case of any Note selected for partial
redemption, the principal amount thereof to be redeemed. Notes and portions of

whole multiples of $1,000; except that if all of the Notes of a Holder are to be
redeemed, the entire outstanding amount of Notes held by such Holder, even if
not a multiple of $1,000, shall be redeemed. Except as provided in the preceding
sentence, provisions of this Indenture that apply to Notes called for redemption
also apply to portions of Notes called for redemption.

SECTION 3.3.    NOTICE OF REDEMPTION.

         At least 30 days but not more than 60 days before a redemption date,
the Company shall mail or cause to be mailed, by first class mail, a notice of
redemption to each Holder whose Notes are to be redeemed at such Holder's
registered address.

         The notice shall identify the Notes to be redeemed and shall state:

         (a) the redemption date;

         (b) the redemption price and accrued and unpaid interest;

         (c) if any Note is being redeemed in part, the portion of the principal
amount of such Note to be redeemed and that, after the redemption date upon
surrender of such Note, a new Note or Notes in principal amount equal to the
unredeemed portion shall be issued upon cancellation of the original Note;

         (d) the name and address of the Paying Agent;

         (e) that Notes called for redemption must be surrendered to the Paying
Agent to collect the redemption price;

         (f) that, unless the Company defaults in making such redemption
payment, interest on Notes called for redemption ceases to accrue on and after
the redemption date and the only remaining right of the Holders of such Notes is
to receive payment of the redemption price upon surrender to the Paying Agent of
the Notes redeemed;

         (g) the paragraph of the Notes and/or Section of this Indenture
pursuant to which the Notes called for redemption are being redeemed; and

         (h) that no representation is made as to the correctness or accuracy of
the CUSIP number, if any, listed in such notice or printed on the Notes.

         At the Company's request, the Trustee shall give the notice of
redemption in the Company's name and at its expense; provided, however, that the
Company shall have delivered to the Trustee, at least 40 days prior to the
redemption date (unless a shorter period is acceptable to the Trustee), an
Officers' Certificate requesting that the Trustee give such notice and setting
forth the information to be stated in such notice as provided in the preceding
paragraph.

SECTION 3.4.    EFFECT OF NOTICE OF REDEMPTION.

         Unless otherwise stated therein, once notice of redemption is mailed in
accordance with Section 3.3 hereof, Notes called for redemption become
irrevocably due and payable on the redemption date at the redemption price.

SECTION 3.5.    DEPOSIT OF REDEMPTION PRICE.

         On or prior to the redemption date, the Company shall deposit with the
Paying Agent (other than the Company or any of its Subsidiaries) money
sufficient in same day funds to pay the redemption price of and accrued interest
on all Notes to be redeemed on that date. The Paying Agent shall promptly return
to the Company any money deposited with the Paying Agent by the Company in
excess of the amounts necessary to pay the redemption price of, and accrued
interest on, all Notes to be redeemed. If the money is deposited on the
redemption date, such deposit shall be made by 10:00 a.m. New York City time.

         If the Company complies with the provisions of the preceding paragraph,
on and after the redemption date, interest shall cease to accrue on the Notes or
the portions of Notes called for redemption whether or not such Notes are
presented for payment, and the only remaining right of the Holders of such Notes
shall be to receive payment of the redemption price upon surrender to the Paying
Agent of the Notes redeemed. If a Note is redeemed on or after an interest
record date but on or prior to the related interest payment date, then any
accrued and unpaid interest shall be paid to the Person in whose name such Note
was registered at the close of business on such record date. If any Note called
for redemption shall not be so paid upon surrender for redemption because of the
failure of the Company to comply with the preceding paragraph, interest shall be
paid on the unpaid principal from the redemption date until such principal is
paid and to the extent lawful, on any interest not paid on such unpaid
principal, in each case at the rate provided in the Notes and in Section 4.1
hereof.

SECTION 3.6.    NOTES REDEEMED IN PART.

         Upon surrender of a Note that is redeemed in part, the Company shall
issue and, upon the Company's written request, the Trustee shall authenticate
for the Holder at the expense of the Company a new Note equal in principal
amount to the unredeemed portion of the Note surrendered.

provided, further, that notice of such redemption shall have been given not
later than 30 days, and such redemption shall occur not later than 90 days,

change in the location of any such other office or agency.

(ii) such as for which reserve or other appropriate provision, if any, as shall
be required to be in conformity with GAAP, has been made therefor, or (iii)
where the failure to effect such payment is not adverse in any material respect
to the Holders of the Notes.

SECTION 4.6.    STAY, EXTENSION AND USURY LAWS.

         The Company and each Subsidiary Guarantor covenants (to the extent that
it may lawfully do so) that it shall not at any time insist upon, plead, or in

                  (ii) the Company would, at the time of such Restricted Payment
         and after giving pro forma effect thereto as if such Restricted Payment
         had been made at the beginning of the applicable fiscal quarter, have
         been permitted to Incur at least $1.00 of additional Indebtedness
         pursuant to the Consolidated Interest Coverage Ratio test set forth in
         Section 4.9(a); and

                  (iii) such Restricted Payment, together with the aggregate

         cash proceeds received by the Company as capital contributions to the
         Company (other than from a Subsidiary of the Company) after the Closing
         Date, plus (4) if any Restricted Investment that was made after the
         Closing Date is sold for cash, to the extent such amount is not
         included in the Consolidated Net Income of the Company, the lesser of
         (A) the Net Proceeds from such sale to the extent received by the
         Company or any Restricted Subsidiary, and (B) the initial amount of
         such Restricted Investment, plus (5) in the event an Unrestricted
         Subsidiary is redesignated as a Restricted Subsidiary, an amount equal
         to the lesser of (A) the book value of such Unrestricted Subsidiary,
         and (B) the Fair Market Value of such Unrestricted Subsidiary.

         (b) The foregoing provisions of this Section 4.7 shall not prohibit the
following Restricted Payments:



                                       32
<PAGE>   40

                  (i) the payment of any dividend or other distribution within
         60 days after the date of declaration thereof, if at said date of
         declaration such payment would have complied with the provisions of
         this Indenture;

                  (ii) the redemption, repurchase, retirement or other

         substantially concurrent sale (other than to a Subsidiary of the
         Company) of other Equity Interests of the Company (other than
         Disqualified Stock); provided that the amount of any such net cash
         proceeds that are utilized for any such redemption, repurchase,
         retirement or other acquisition shall be excluded from clause (iii) of
         the preceding subsection 4.7(a) (both for purposes of determining the
         aggregate amount of Restricted Payments made and for purposes of
         determining the aggregate amount of Restricted Payments permitted);

                  (iii) the payment, purchase, redemption, defeasance or other
         acquisition or retirement for value of Subordinated Indebtedness with
         the net cash proceeds from a substantially concurrent Incurrence of
         Permitted Refinancing Indebtedness or the substantially concurrent sale
         (other than to a Subsidiary of the Company) of Equity Interests of the
         Company (other than Disqualified Stock); provided that the amount of
         any such net cash proceeds that are utilized for any such payment,
         purchase, redemption, defeasance or other acquisition or retirement
         shall be excluded from clause (iii) of the preceding subsection 4.7(a)
         (both for purposes of determining the aggregate amount of Restricted
         Payments made and for purposes of determining the aggregate amount of
         Restricted Payments permitted);

                  (iv) any Restricted Investment made with the net cash proceeds
         from a substantially concurrent sale (other than to a Subsidiary of the
         Company) of Equity Interests of the Company (other than Disqualified
         Stock); and

                  (v) so long as no Default or Event of Default is continuing,
         any Restricted Investment which, together with all other Restricted
         Investments outstanding made pursuant to this clause (v) does not
         exceed $3 million.

         Except to the extent specifically noted above, Restricted Payments made
pursuant to this Section 4.7(b) shall be included in calculating the amount of
Restricted Payments made after the Closing Date.

         (c) The Board of Directors of the Company may designate any Restricted
Subsidiary to be an Unrestricted Subsidiary if (i) such designation would not
cause a Default or Event of Default, (ii) at the time of and after giving effect
to such designation, the Company could incur $1.00 of additional Indebtedness
pursuant to the Consolidated Interest Coverage Ratio test set forth in Section
4.9(a), and (iii) each of the other requirements of the definition of the term
"Unrestricted Subsidiary" are satisfied. For purposes of making such
determination, 


                                       33
<PAGE>   41

all outstanding Investments by the Company and its Restricted Subsidiaries
(except to the extent repaid in cash) in the Subsidiary so designated will be
deemed to be Restricted Payments at the time of such designation and will reduce
the amount available for Restricted Payments under the first paragraph of this
covenant. All such outstanding Investments will be deemed to constitute
Restricted Payments in an amount equal to the greater of (i) the net book value
of such Investments at the time of such designation and (ii) the Fair Market
Value of such Investments at the time of such designation. Such designation will
only be permitted if such Restricted Payment would be permitted at such time and
if such Restricted Subsidiary otherwise meets the definition of an Unrestricted
Subsidiary. Upon being so designated as an Unrestricted Subsidiary, any
Subsidiary Guarantee that was previously executed by such Unrestricted
Subsidiary shall be deemed terminated.

         (d) The amount of all Restricted Payments not made in cash shall be the
Fair Market Value (which, if it exceeds $1 million, shall be determined by, and
set forth in, a resolution of the Board of Directors of the Company and
described in an Officers' Certificate delivered to the Trustee) on the date of
the Restricted Payment of the asset(s) proposed to be transferred by the Company
or any Restricted Subsidiary, as the case may be, pursuant to the Restricted
Payment. Not later than the date of making any Restricted Payment, the Company
shall deliver to the Trustee an Officers' Certificate stating that such
Restricted Payments during such quarter were permitted and setting forth the
basis upon which the calculations required by this Section 4.7 were computed,
which calculations may be based upon the Company's latest available financial
statements.

SECTION 4.8. LIMITATION ON DIVIDEND AND OTHER PAYMENT RESTRICTIONS AFFECTING
RESTRICTED SUBSIDIARIES.

         The Company will not, and will not permit any of its Restricted
Subsidiaries to, directly or indirectly, create or otherwise cause or suffer to
exist or become effective any consensual encumbrance or restriction on the
ability of any Restricted Subsidiary to (i)(a) pay dividends or make any other
distributions to the Company or any of its Restricted Subsidiaries on its
Capital Stock or with respect to any other interest or participation in, or
measured by, its profits or (b) pay any Indebtedness owed to the Company or any

any of its Restricted Subsidiaries, (iii) transfer any of its properties to the
Company or any of its Restricted Subsidiaries, (iv) grant any Liens in favor of

renewals or refinancings thereof, except for such encumbrances or restrictions
existing under or by reason of (A) Existing Indebtedness, (B) the Bank Credit
Agreement, (C) applicable law, (D) any instrument governing Indebtedness or
Capital Stock of a Person acquired by the Company or any of its Restricted
Subsidiaries as in effect at the time of such acquisition (except to the extent
such Indebtedness was Incurred in connection with or in contemplation of such
acquisition), which encumbrance or restriction is not applicable to any Person,
or the properties of any Person, other than the Person, or the property of the
Person, so acquired, provided that in the case of Indebtedness, such
Indebtedness was permitted by the terms of this Indenture to be Incurred, (E)
customary non-assignment provisions in leases, licenses, sales agreements or
other contracts 


                                       34

(but excluding contracts related to the extension of credit) entered into in the
ordinary course of business and consistent with past practices, (F) restrictions
imposed pursuant to a binding agreement for the sale or disposition of all or
substantially all of the Equity Interests or assets of any Restricted
Subsidiary, provided such restrictions apply solely to the Equity Interests or
assets being sold, (G) restrictions imposed by Permitted Liens on the transfer
of the assets that are subject to such Liens, and (H) Permitted Refinancing
Indebtedness Incurred to refinance Existing Indebtedness or Indebtedness of the
type described in clause (D) above, provided that the restrictions contained in
the agreements governing such Permitted Refinancing Indebtedness are no more
restrictive, as a whole, than those contained in the agreements governing the
Indebtedness being refinanced.

SECTION 4.9.    LIMITATION ON INDEBTEDNESS.

         (a) The Company will not, and will not permit any of its Restricted
Subsidiaries to, directly or indirectly, Incur any Indebtedness (including
Acquired Indebtedness), except for Permitted Indebtedness, unless (i) at the
time of such event and after giving effect thereto on a pro forma basis the
Company's Consolidated Interest Coverage Ratio for the four full fiscal quarters
immediately preceding such event, taken as one period, would have been at least
equal to (A) 2.0 to 1.0 for the first two years after the Closing Date and (B)
2.25 to 1.0 thereafter and (ii) no Default or Event of Default shall have
occurred and be continuing at the time such additional Indebtedness is Incurred
or would occur as a consequence of the Incurrence of such additional
Indebtedness.

         (b) "Permitted Indebtedness" means any and all of the following:

                  (i) Indebtedness of the Company and its Restricted
         Subsidiaries pursuant to the Bank Credit Agreement (including all
         Guarantees thereof) in an aggregate amount not to exceed the greater of
         (A) $20 million or (B) 85% of Eligible Receivables, less the aggregate
         amount of all payments thereon which are applied to permanently reduce
         the outstanding amount of or the commitments with respect to such
         Indebtedness;

                  (ii) Indebtedness represented by the Notes, this Indenture,
         the Subsidiary Guarantees and the Pledge Agreement;

                  (iii) intercompany Indebtedness between or among the Company
         and any of its Restricted Subsidiaries; provided that (A) if the
         Company is an obligor on such Indebtedness, such Indebtedness is
         expressly subordinate to the payment in full of all Obligations with
         respect to the Notes and (B) any subsequent issuance or transfer of
         Equity Interests that results in any such Indebtedness being held by a
         Person other than the Company or a Restricted Subsidiary of the
         Company, or any sale or other transfer of any such Indebtedness to a
         Person that is not either the Company or a Restricted Subsidiary of the
         Company, shall be 


                                       35
<PAGE>   43

         deemed to constitute a new Incurrence of such Indebtedness by the
         Company or such Restricted Subsidiary, as the case may be;

                  (iv) Permitted Refinancing Indebtedness Incurred in exchange
         for, or the net proceeds of which are used to extend, refinance, renew,
         replace, defease or refund, (A) Indebtedness (other than Permitted
         Indebtedness) that was Incurred in compliance with this Indenture, (B)
         Indebtedness referred to in clause (b) (ii) of this Section, or (C)
         Existing Indebtedness;

                  (v) Indebtedness of a Restricted Subsidiary of the Company
         constituting a Guarantee of Indebtedness of the Company or a Restricted
         Subsidiary which Indebtedness was Incurred pursuant to this Section
         4.9(b) or the Consolidated Interest Coverage Ratio test set forth in
         Section 4.9(a);

                  (vi) Hedging Obligations of the following types: (A) Interest
         Rate Hedges the notional principal amount of which does not exceed the
         principal amount of the Indebtedness to which such Interest Rate Hedge
         relates, and (B) Currency Hedges that do not increase the outstanding
         loss potential or liabilities other than as a result of fluctuations in
         foreign currency exchange rates;

                  (vii) Indebtedness (in addition to Indebtedness permitted by
         any other clause of this Section 4.9(b)) in an aggregate principal
         amount at any time outstanding not to exceed $5 million; and

                  (viii) Existing Indebtedness.

         (c) For purposes of determining compliance with this Section 4.9, (i)
in the event that an item of Indebtedness meets the criteria of more than one of
the types of Indebtedness described herein, the Company, in its sole discretion,
will classify such item of Indebtedness and only be required to include the
amount and type of such Indebtedness in one of the above clauses and (ii) an
item of Indebtedness may be divided and classified in more than one of the types
of Indebtedness described herein.

SECTION 4.10.     LIMITATION ON ASSET SALES.

         (a) The Company will not, and will not permit any of its Restricted
Subsidiaries to, engage in an Asset Sale unless (i) the Company or such
Restricted Subsidiary, as the case may be, receives consideration at the time of
such Asset Sale at least equal to the Fair Market Value (which, if it exceeds $1
million, shall be determined by, and set forth in, a resolution of the Board of
Directors of the Company and described in an Officers' Certificate of the
Company delivered to the Trustee) of the assets (including, if appropriate,
Equity Interests) disposed of or issued, as appropriate, and (ii) at least 75%
of the consideration therefor received by the Company or such Restricted
Subsidiary is in the form of cash or Cash Equivalents. For purposes of this
Section (and not for purposes of any other provision of this 


                                       36
<PAGE>   44

Indenture), the term "cash" shall be deemed to include (i) any notes or other
obligations received by the Company or such Restricted Subsidiary as
consideration as part of such Asset Sale that are immediately converted by the
Company or such Restricted Subsidiary into actual cash (to the extent of the
actual cash so received), and (ii) any liabilities of the Company or such
Restricted Subsidiary (as shown on the most recent balance sheet of the Company
or such Restricted Subsidiary) that (A) are assumed by the transferee of the
assets which are the subject of such Asset Sale as consideration therefor in a
transaction the result of which is that the Company and all of its Subsidiaries
are released from all liability for such assumed liability, (B) are not by their
terms subordinated in right of payment to the Notes, (C) are not owed to the
Company or any Subsidiary of the Company, and (D) constitute short-term
liabilities (as determined in accordance with GAAP).

         (b) Within 180 days after the receipt of any Net Proceeds from an Asset
Sale, the Company may apply, directly or indirectly, such Net Proceeds (a) to
permanently reduce Indebtedness under the Bank Credit Agreement (and to
correspondingly reduce commitments with respect thereto) or (b) to invest in
properties and assets that will be used in the Shipyard Business of the Company
and its Restricted Subsidiaries. Pending the final application of any such Net
Proceeds, the Company may temporarily invest such Net Proceeds in any manner
that is not prohibited by this Indenture (including, without limitation, to the
reduction of Indebtedness under the Bank Credit Agreement). Any Net Proceeds
from Asset Sales that are not applied or invested as provided in the first
sentence of this Section 4.10(b) will be deemed to constitute "Excess Proceeds."
When the aggregate amount of Excess Proceeds exceeds $5 million, the Company
will be required to make an offer to all Holders of Notes and, if the Company is
required to do so under the terms of any other senior Indebtedness, to the
holders of such other senior Indebtedness (an "Asset Sale Offer") to purchase
Notes and principal of such other senior Indebtedness, on a pro rata basis,
having an aggregate principal amount equal to the Excess Proceeds, at an offer
price in cash equal to, in the case of the Notes, 100% of the principal amount
thereof, plus accrued and unpaid interest thereon to the date of purchase, and,
in the case of all other senior Indebtedness, 100% of the principal amount
thereof, plus accrued and unpaid interest, or premium, if any, thereon to the
date of purchase, in accordance with the procedures set forth in this Indenture.
To the extent that the aggregate principal amount of Notes tendered pursuant to
an Asset Sale Offer is less than the Excess Proceeds, the Company may use any
remaining Excess Proceeds for general corporate purposes. If the aggregate
principal amount of Notes and such other senior Indebtedness surrendered by
holders thereof exceeds the amount of Excess Proceeds, the Trustee shall select
the Notes to be purchased in compliance with the requirements of the principal
national securities exchange, if any, on which the Notes are listed or, if the
Notes are not so listed, on a pro rata basis with such other senior Indebtedness
based on the outstanding principal amounts thereof (with such adjustments as may
be deemed appropriate by the Company so that only Notes with denominations of
$1,000 or integral multiples thereof shall be purchased). Upon completion of
such offer to purchase, the amount of Excess Proceeds shall be reset at zero.

         (c) The Company will not, and will not permit any of its Restricted
Subsidiaries to, transfer, convey, sell, lease or otherwise dispose of any
Capital Stock of any  


                                       37
<PAGE>   45
Restricted Subsidiary of the Company to any Person (other than the Company or a
Wholly Owned Restricted Subsidiary of the Company), unless (i) such transfer,
conveyance, sale, lease or other disposition is of all of the Capital Stock of
such Restricted Subsidiary owned by the Company and its Restricted Subsidiaries
or is otherwise permitted under Section 4.13 and (ii) such transaction is
conducted in accordance with clauses (a) and (b) above.

         (d) The Company will comply with the requirements of Rule 14e-1 under
the Exchange Act and any other securities laws and regulations thereunder to the
extent such laws and regulations are applicable in connection with the
repurchase of Notes using Excess Proceeds.

SECTION 4.11.     LIMITATION ON TRANSACTIONS WITH AFFILIATES.

         The Company will not, and will not permit any of its Restricted
Subsidiaries to, make any payment to, or sell, lease, transfer or otherwise
dispose of any of its properties or assets to, or purchase any property or
assets from, or enter into or make or amend any contract, agreement,
understanding, loan, advance or guarantee with, or for the benefit of, any
Affiliate of the Company (other than the Company or a Restricted Subsidiary), in
one transaction or a series of transactions (each of the foregoing an "Affiliate
Transaction"), unless (i) such Affiliate Transaction is on terms that are no
less favorable to the Company or the relevant Restricted Subsidiary than those
that would have been obtained in a comparable transaction with an unrelated
Person and (ii) the Company delivers to the Trustee (a) with respect to any
Affiliate Transaction or series of related Affiliate Transactions after the
Closing Date involving aggregate consideration in excess of $500,000, an
Officer's Certificate certifying that such Affiliate Transaction complies with
clause (i) above, (b) with respect to any Affiliate Transaction or series of
related Affiliate Transactions after the Closing Date involving an aggregate
consideration in excess of $2 million, a resolution described in an Officers'
Certificate, certifying that such Affiliate Transaction complies with clause (i)
above and such Affiliate Transaction has been approved by a majority of the
disinterested members of the Board of Directors of the Company and (c) with
respect to any Affiliate Transaction or series of related Affiliate Transactions
after the Closing Date involving aggregate consideration in excess of $5
million, an opinion as to the fairness to the Company of such Affiliate
Transaction from a financial point of view issued by an accounting, appraisal or
investment banking firm of recognized national standing; provided that the
following types of transactions shall not constitute Affiliate Transactions: (1)
any transaction with an officer or director of the Company or any Restricted
Subsidiary in connection with such individual's compensation (including
directors' fees), employee benefits, severance arrangements or indemnification
(to the extent consistent with applicable law and the charter and bylaws of the
Company or such Restricted Subsidiary), in each case entered into by the Company
or any of its Restricted Subsidiaries in the ordinary course of business, (2)
transactions between or among the Company and its Restricted Subsidiaries, (3)
Restricted Payments that are permitted by the provisions of Section 4.7; (4)
sales of Capital Stock of the Company made at prevailing market rates; and (5)
loans to officers, directors and employees of the Company and its Restricted
Subsidiaries made in the ordinary course of business in an aggregate amount not
to exceed $1 million at any one time outstanding.

SECTION 4.12.     LIMITATION ON LIENS.

         The Company will not, and will not permit any of its Restricted
Subsidiaries to, directly or indirectly, create, incur, affirm, assume or suffer
to exist any Lien of any kind on any property now owned or hereafter acquired,
or any income or profits therefrom or assign or convey any right to receive
income therefrom, unless (i) in the case of Liens securing obligations
subordinate to the Notes, the Notes are secured by a valid, perfected Lien on
such property that is senior in priority to such Liens, (ii) in the case of
Liens securing obligations subordinate to a Subsidiary Guarantee, such
Subsidiary Guarantee is secured by a valid, perfected Lien on such property that
is senior in priority to such Liens, and (iii) in all other cases, the Notes
(and, if such Lien secures obligations of a Restricted Subsidiary, a Subsidiary
Guarantee of such Restricted Subsidiary) are equally and ratably secured;
provided, however, that the foregoing shall not prohibit or restrict Permitted
Liens.

SECTION 4.13. LIMITATION ON ISSUANCE AND SALE OF CAPITAL STOCK OF RESTRICTED
SUBSIDIARIES.

         The Company will not, and will not permit any Restricted Subsidiary to
(i) sell, assign, transfer, convey or otherwise dispose of, any Equity Interests
of any Restricted Subsidiary, other than to the Company or a Wholly Owned
Restricted Subsidiary, (ii) permit any Restricted Subsidiary to issue any Equity
Interests (including, without limitation, pursuant to any merger, consolidation,
recapitalization or similar transaction) other than to the Company or a Wholly
Owned Restricted Subsidiary or (iii) permit any Person other than the Company or
a Wholly Owned Restricted Subsidiary to own any Equity Interests of any
Restricted Subsidiary, except for (A) a sale to a Person of all of the Equity
Interests of a Restricted Subsidiary, which sale was made by the Company or a
Restricted Subsidiary subject to, and in compliance with, Section 4.10, (B) the
issuance and subsequent ownership of directors' qualifying shares, and (C) the
Equity Interests of a Restricted Subsidiary owned by a Person at the time such
Restricted Subsidiary became a Restricted Subsidiary or acquired by such Person
in connection with the formation of the Restricted Subsidiary, provided that the
Equity Interests owned by such Person do not exceed 20% of the total Equity
Interests of such Restricted Subsidiary.

SECTION 4.14.     OFFER TO REPURCHASE UPON CHANGE OF CONTROL.

         (a) Upon the occurrence of a Change of Control, the Company will be
required to make an offer (a "Change of Control Offer") to repurchase all or any
part (equal to $1,000 or an integral multiple thereof) of each Holder's Notes,
at an offer price in cash equal to 101% of the aggregate principal amount
thereof, plus accrued and unpaid interest thereon, to the date of repurchase
(the "Change of Control Payment").

         (b) Notice of a Change of Control Offer shall be mailed by the Company,
with a copy to the Trustee, or, at the Company's option, by the Trustee (at the
Company's expense) not more than 20 calendar days after the Change of Control to

the Register. In such notice, the Company shall 


                                       39
<PAGE>   47

describe the transaction that constitutes the Change of Control and offer to
repurchase Notes pursuant to the procedures required by this Section 4.14 and
described in such notice. The notice shall contain all instructions and
materials necessary to enable Holders to tender Notes pursuant to the Change of
Control Offer. In addition, the notice shall state: (1) that the Change of
Control Offer is being made pursuant to this Section 4.14 and that all Notes (or
portions thereof) properly tendered will be accepted for payment; (2) the Change
of Control Payment and the purchase date, which shall be no sooner than 30 nor
later than 60 days from the date on which the Company notifies the Holders of
the occurrence of the Change of Control (the "Change of Control Payment Date");
(3) that any Note (or portion thereof) not properly tendered will continue to
accrue interest; (4) that, unless the Company defaults in the payment of the
Change of Control Payment, all Notes (or portions thereof) accepted for payment
pursuant to the Change of Control Offer shall cease to accrue interest after the
Change of Control Payment Date; and (5) the procedures that Holders of Notes
must follow in order to tender their Notes (or portions thereof) for payment and
the procedures that Holders of Notes must follow in order to withdraw an

tendered pursuant to the Change of Control Offer, (ii) deposit with the Trustee
an amount equal to the Change of Control Payment in respect of all Notes or
portions thereof so tendered and (iii) deliver or cause to be delivered to the
Trustee the Notes so accepted together with an Officers' Certificate stating the
aggregate principal amount of Notes or portions thereof being purchased by the
Company. The Trustee will promptly mail to each Holder of Notes so tendered the
Change of Control Payment for such Notes, and the Trustee will promptly
authenticate and mail (or cause to be transferred by book entry) to each Holder
a new Note equal in principal amount to any unpurchased portion of the Notes
surrendered, if any; provided that each such new Note will be in a principal
amount of $1,000 or an integral multiple thereof. The Company will publicly
announce the results of the Change of Control Offer on or as soon as practicable
after the Change of Control Payment Date. Unless the Company defaults in the
payment for any Notes properly tendered pursuant to the Change of Control Offer,
any Notes accepted for payment pursuant to the Change of Control Offer shall
cease to accrue interest after the Change of Control Payment Date.

         (d) The Company will not be required to make a Change of Control Offer
upon a Change of Control if a third party makes the Change of Control Offer in
the manner, at the times and otherwise in compliance with the requirements set
forth in this Section 4.14 applicable to a Change of Control Offer made by the
Company and purchases all Notes validly tendered and not withdrawn under such
Change of Control Offer.

         The Company will not, and will not permit any of its Restricted
Subsidiaries to, enter into any sale and leaseback transaction; provided that
the Company or any Restricted Subsidiary may enter into a sale and leaseback
transaction if (a) the Company could have (i) Incurred Indebtedness in an amount
equal to the Attributable Debt relating to such sale and leaseback transaction
pursuant to either (1) the Consolidated Interest Coverage Ratio test set forth

other existence of each of its Subsidiaries, in accordance with their respective
organizational documents (as the same may be amended from time to time), and

Company and its Subsidiaries; provided, however, that the Company shall not be
required to preserve any such right, license or franchise of itself or any of
its Subsidiaries, or the corporate, partnership or other existence of any of its
Subsidiaries, if the Board of Directors shall determine that the preservation
thereof is no longer desirable in the conduct of the business of the Company and
its Subsidiaries, taken as a whole, and that the loss thereof is not adverse in
any material respect to the Holders of the Notes.

SECTION 4.18.     PLEDGE ACCOUNT

         The Company shall, on the date hereof, enter into the Pledge Agreement,
and pursuant thereto, shall purchase and pledge to the Trustee, for the benefit
of the Holders of the Notes, the Pledged Securities, in such amount as will be
sufficient upon receipt of scheduled interest and principal payments of such
securities, in the opinion of a nationally recognized firm of independent public
accountants selected by the Company (to be delivered promptly after the Closing
Date), to provide for payment in full when due of the first two scheduled
interest payments on the Notes. If for any reason the Pledged Securities,
together with the other funds in the Pledge Account, shall not, in the opinion
of such independent public accounting firm, be sufficient to provide for payment
of such first two interest payments, the Company shall immediately pledge to the
Trustee pursuant to the Pledge Agreement additional Pledged Securities or other
funds in such amounts as shall be sufficient, in the opinion of such 

                                       41

firm with regard thereto.

         and (c) above and (i) below) and such failure continues for 30 calendar
         days after receipt by the Company of a notice of default specifying
         such Default;

                  (e) a default under any mortgage, indenture or instrument
         under which there may be issued or by which there may be secured or
         evidenced any Indebtedness for money borrowed by the Company or any of
         its Restricted Subsidiaries (or the payment of which is Guaranteed by
         the Company or any of its Restricted Subsidiaries), whether such
         Indebtedness or Guarantee now exists or is created after the date of
         this Indenture, which default (i) is caused by a failure to pay
         principal of or premium, if any, or interest on such Indebtedness
         following the expiration of the grace period provided in such
         Indebtedness on the date of such default (a "Payment Default") or (ii)
         results in the acceleration of such Indebtedness (including any
         obligation to redeem or repurchase such Indebtedness) prior to its
         express maturity and, in each case, the principal amount of any such
         Indebtedness, together with the principal amount of any other such
         Indebtedness under which there has been a Payment Default or the
         maturity of which has been so accelerated, aggregates $1 million or
         more;

                  (f) failure by the Company or any of its Restricted
         Subsidiaries to pay final non-appealable judgments rendered against the
         Company or any of its Restricted Subsidiaries aggregating in excess of
         $1 million, which judgments are not paid, discharge or stayed for a
         period of 60 calendar days after such judgments become final and
         non-appealable;

                  (g) the Company or any Restricted Subsidiary of the Company
         pursuant to or within the meaning of any Bankruptcy Law: (i) commences
         a voluntary case or proceeding, (ii) consents to the entry of an order
         for relief against it in an involuntary case or proceeding, (iii)
         consents to the appointment of a Custodian of it or for all or
         substantially all of its property, (iv) makes a general assignment for
         the benefit of its creditors, or (v) admits in writing its inability to
         pay its debts generally as they become due;

                  (h) a court of competent jurisdiction enters an order or
         decree under any Bankruptcy Law that: (i) is for relief against the
         Company or any Restricted Subsidiary of the Company in an involuntary
         case or proceeding, (ii) appoints a Custodian of the 


                                       44

<PAGE>   52

         Company or any Restricted Subsidiary of the Company or for all or
         substantially all of its respective properties, (iii) orders the
         liquidation of the Company or any Restricted Subsidiary of the Company,
         (iv) adjudicates the Company or any Restricted Subsidiary of the
         Company as bankrupt or insolvent, or (v) ratifies an accord or
         composition in bankruptcy between the Company or a Restricted
         Subsidiary and the respective creditors thereof; and in each case the
         order or decree remains unstayed and in effect for 60 calendar days;

                  (i) breach by the Company of any representation or warranty
         set forth in the Pledge Agreement, or default by the Company in the
         performance of any covenant set forth in the Pledge Agreement and the
         expiration of any cure period set forth therein, or repudiation by the
         Company of any of its obligations under the Pledge Agreement or the
         unenforceability of the Pledge Agreement against the Company for any
         reason (other than as permitted pursuant to the terms thereof), which
         in any one of the foregoing cases or in the aggregate results in a
         material impairment of the rights intended to be afforded thereby; or

                  (j) any Guarantee of the Notes shall be held in a judicial
         proceeding to be unenforceable or invalid or shall cease for any reason
         to be in full force and effect, or any Restricted Subsidiary, or any
         Person acting on behalf of any Restricted Subsidiary, shall deny or
         disaffirm its obligations under its Guarantee of any Notes.

         A Default under clause (d) above is not an Event of Default until the
Trustee notifies the Company, or the Holders of at least 25% in aggregate
principal amount of the Notes at the time outstanding notify the Company and the
Trustee, of the Default and the Company does not cure such Default within the
time period specified in clause (d) above after receipt of such notice. Such
notice must be in writing and specify the Default, demand that it be remedied
and state that the notice is a "Notice of Default."

SECTION 6.2.    ACCELERATION.

         If any Event of Default (other than an Event of Default described in
clauses (g) and (h) of Section 6.1 hereof) occurs and is continuing, then the
Trustee or the Holders of at least 25% in aggregate principal amount of the then
outstanding Notes by written notice to the Company (and to the Trustee, if given
by the Holders) may declare the unpaid principal of, and any accrued interest
on, all the Notes to be due and payable immediately. If any Event of Default
specified in clauses (g) or (h) of Section 6.1 hereof occurs, all outstanding
principal and interest on the Notes shall be immediately due and payable without
any declaration or other act on the part of the Trustee or any Holder. The
Holders of a majority in aggregate principal amount of the Notes then
outstanding, by written notice to the Trustee and to the Company, may rescind an
acceleration (except an acceleration due to a default in payment of the
principal of, premium or interest on any of the Notes) if the rescission would
not conflict with any judgment or decree and if all existing Events of Default
(except nonpayment of principal, premium or interest that have become due solely
because of the acceleration) have been cured or waived.

                                       45


<PAGE>   53

         In the case of any Event of Default occurring by reason of any willful
action (or inaction) taken (or not taken) by or on behalf of the Company or a
Restricted Subsidiary with the intention of avoiding payment of the premium that
the Company would have had to pay if the Company then had elected to redeem the
Notes pursuant to Section 3.7(a), an equivalent premium shall also become and be
immediately due and payable to the extent permitted by law upon the acceleration
of the Notes. If an Event of Default occurs prior to February 1, 2003 by reason
of any willful action (or inaction) taken (or not taken) by or on behalf of the
Company or a Restricted Subsidiary with the intention of avoiding the
prohibition on redemption of the Notes prior to such date, then the premium
specified in Section 3.7(b) shall also become immediately due and payable to the
extent permitted by law upon the acceleration of the Notes.

SECTION 6.3.    OTHER REMEDIES.

         Subject to Section 6.2, if an Event of Default occurs and is
continuing, the Trustee may pursue any available remedy by proceeding at law or
in equity to collect any payment due on the Notes or to enforce the performance
of any provision of the Notes or this Indenture.

         The Trustee may maintain a proceeding even if it does not possess any
of the Notes or does not produce any of them in the proceeding. A delay or
omission by the Trustee or any Holder of a Note in exercising any right or
remedy accruing upon an Event of Default shall not impair the right or remedy or
constitute a waiver of or acquiescence in the Event of Default. All remedies are
cumulative to the extent permitted by law.

SECTION 6.4.    WAIVER OF PAST DEFAULTS.

         Subject to Section 9.2, Holders of a majority in aggregate principal
amount of the then outstanding Notes by notice to the Trustee may, on behalf of
the Holders of all of the Notes, waive an existing Default or Event of Default
and its consequences hereunder except a continuing Default or Event of Default
in the payment of the principal of, premium or interest on the Notes. Upon any
such waiver, such Default shall cease to exist, and any Event of Default arising
therefrom shall be deemed to have been cured for every purpose of this
Indenture; but no such waiver shall extend to any subsequent or other Default or
impair any right consequent thereon.

SECTION 6.5.    CONTROL BY MAJORITY.

         The Holders of a majority in aggregate principal amount of the Notes
then outstanding may direct the time, method and place of conducting any
proceeding for any remedy available to the Trustee or exercising any trust or
power conferred on it. However, the Trustee may refuse to follow any direction
that conflicts with law or this Indenture or that the Trustee determines may be
unduly prejudicial to the rights of another Holder or that involves the Trustee
in personal liability. The Trustee may take any other action deemed proper by
the Trustee that is not inconsistent with such direction.

                                       46

<PAGE>   54

SECTION 6.6.    Limitation on Suits.

         Subject to the provisions of Section 6.7 hereof, no Holder of a Note
may pursue any remedy with respect to this Indenture or the Notes (including
without limitation the institution of any proceeding, judicial or otherwise,
with respect to the Notes or this Indenture or for the appointment of a receiver
or trustee for the Company and/or any of its Subsidiaries) unless:

                  (a) the Holder has given to the Trustee written notice of a 
         continuing Event of Default;

                  (b) the Holders of at least 25% in aggregate principal amount
         of the Notes then outstanding have made a written request to the
         Trustee to pursue the remedy;

                  (c) such Holders have offered to provide to the Trustee
         indemnity reasonably satisfactory to the Trustee against any loss,
         liability or expense;

                  (d) the Trustee has not complied with the request within 60
         calendar days after receipt of the request and the offer of indemnity;
         and

                  (e) during such 60-day period, the Holders of a majority in
         aggregate principal amount of the Notes then outstanding have not given
         the Trustee a direction which, in the opinion of the Trustee, is
         inconsistent with the request.

         A Holder of a Note may not use this Indenture to prejudice the rights
of another Holder of a Note or to obtain a preference or priority over another
Holder of a Note.

SECTION 6.7.    RIGHTS OF HOLDERS OF NOTES TO RECEIVE PAYMENT.

         Notwithstanding any other provision of this Indenture, the right of any
Holder of a Note to receive payment of principal of, and premium, if any, and
interest on, the Note, on or after the respective due dates expressed in the
Note (including in connection with an offer to purchase), or to bring suit for
the enforcement of any such payment on or after such respective dates, shall not
be impaired or affected without the consent of such Holder.

SECTION 6.8.    COLLECTION SUIT BY TRUSTEE.

         If an Event of Default specified in Section 6.1(a) or (b) occurs and is
continuing, the Trustee is authorized to recover judgment in its own name and as
trustee of an express trust against the Company for principal of, and premium,
if any, and interest on, the Notes and interest on overdue principal and, to the
extent lawful, interest, and such further amount as shall be sufficient to cover
the costs and expenses of collection, including the reasonable compensation,
expenses, disbursements and advances of the Trustee, its agents and counsel.

                                       47

<PAGE>   55

SECTION 6.9.    TRUSTEE MAY FILE PROOFS OF CLAIM.

         The Trustee is authorized to file such proofs of claim and other papers
or documents as may be necessary or advisable in order to have the claims of the
Trustee (including any claim for the reasonable compensation, expenses,
disbursements and advances of the Trustee, its agents and counsel) and the
Holders of the Notes allowed in any judicial proceedings relative to the Company
(or any other obligor upon the Notes), its creditors or its property and shall
be entitled and empowered to collect, receive and distribute any money or other
property payable or deliverable on any such claims and any custodian in any such
judicial proceeding is hereby authorized by each Holder to make such payments to
the Trustee, and in the event that the Trustee shall consent to the making of
such payments directly to the Holders, to pay to the Trustee any amount due to
it for the reasonable compensation, expenses, disbursements and advances of the
Trustee, its agents and counsel, and any other amounts due the Trustee under
Section 7.7 hereof. To the extent that the payment of any such reasonable
compensation, expenses, disbursements and advances of the Trustee, its agents
and counsel, and any other amounts due the Trustee under Section 7.7 hereof out
of the estate in any such proceeding, shall be denied for any reason, payment of
the same shall be secured by a Lien on, and shall be paid out of, any and all
distributions, dividends, money, securities and other properties that the
Holders may be entitled to receive in such proceeding whether in liquidation or
under any plan of reorganization or arrangement or otherwise. Nothing herein
contained shall be deemed to authorize the Trustee to authorize or consent to or
accept or adopt on behalf of any Holder any plan of reorganization, arrangement,
adjustment or composition affecting the Notes or the rights of any Holder, or to
authorize the Trustee to vote in respect of the claim of any Holder in any such
proceeding.

SECTION 6.10.     PRIORITIES.

         If the Trustee collects any money pursuant to this Article 6, it shall
pay out the money in the following order:

         First: to the Trustee for amounts due under Section 7.7 hereof,
including payment of all compensation, expense and liabilities incurred, and all
advances made, by the Trustee and the costs and expenses of collection;

         Second: to Holders of Notes for amounts due and unpaid on the Notes for
principal, premium, if any, and interest ratably, without preference or priority
of any kind, according to the amounts due and payable on the Notes for
principal, premium, if any, and interest, respectively; and

         Third: the remainder to the Company or to such party as a court of
competent jurisdiction shall direct.

         The Trustee may fix a record date and payment date for any payment to
Holders of Notes pursuant to this Section 6.10. At least 15 calendar days before
such record date, the 

                                       48

<PAGE>   56

Company shall mail to each Holder and the Trustee a notice that states the
record date, the payment date and the amount to be paid.

SECTION 6.11.      UNDERTAKING FOR COSTS.

         In any suit for the enforcement of any right or remedy under this
Indenture or in any suit against the Trustee for any action taken or omitted by
it as a Trustee, each party to this Indenture agrees, and each Holder by its
acceptance of its Notes shall be deemed to have agreed, that any court in its
discretion may require the filing by any party litigant in the suit of an
undertaking to pay the costs of the suit, and the court in its discretion may
assess reasonable costs, including reasonable attorneys' fees, against any party
litigant in the suit, having due regard to the merits and good faith of the
claims or defenses made by the party litigant. This Section does not apply to a
suit by the Trustee, a suit by a Holder of a Note pursuant to Section 6.7
hereof, or a suit by Holders of more than 10% in principal amount of the then
outstanding Notes.


                                    ARTICLE 7

                                     TRUSTEE

SECTION 7.1.    DUTIES OF TRUSTEE.

         (a) If an Event of Default has occurred and is continuing, the Trustee
shall exercise such of the rights and powers vested in it by this Indenture, and
use the same degree of care and skill in its exercise, as a prudent Person would
exercise or use under the circumstances in the conduct of its own affairs.

         (b) Except during the continuance of an Event of Default:

            (i) the Trustee shall not be liable hereunder except for such duties
of the Trustee which shall be determined solely by the express provisions of
this Indenture and the Trustee need perform only those duties that are
specifically set forth in this Indenture and no others, and no implied covenants
or obligations shall be read into this Indenture against the Trustee; and

            (ii) in the absence of bad faith on its part, the Trustee may 
conclusively rely, as to the truth of the statements and the correctness of the
opinions expressed therein, upon certificates or opinions furnished to the
Trustee and conforming to the requirements of this Indenture. However, the
Trustee shall examine the certificates and opinions to determine whether or not
such documents conform to the requirements of this Indenture.

         (c) The Trustee may not be relieved from liabilities for its own
negligent action, its own negligent failure to act, or its own willful
misconduct, except that:


                                       49

<PAGE>   57

            (i) this paragraph does not limit the effect of paragraph (b) of 
this Section;

            (ii) the Trustee shall not be liable for any error of judgment made
in good faith by a Responsible Officer, unless it is proved that the Trustee was
negligent in ascertaining the pertinent facts; and

            (iii) the Trustee shall not be liable with respect to any action it 
takes or omits to take in good faith in accordance with a direction received by
it pursuant to Section 6.5 hereof.

         (d) Whether or not therein expressly so provided, every provision of
this Inden ture that in any way relates to the Trustee is subject to paragraphs
(a), (b), and (c) of this Section 7.1.

         (e) No provision of this Indenture shall require the Trustee to expend
or risk its own funds or incur any liability whatsoever in the performance of
any of its duties hereunder or in the exercise of any of its rights or powers
hereunder. The Trustee shall be under no obligation to exercise any of its
rights and powers under this Indenture at the request of any Holders, unless
such Holder shall have offered to the Trustee security and indemnity
satisfactory to it in its sole subjective discretion (which discretion shall be
exercised in good faith) against any loss, liability or expense.

         (f) The Trustee shall not be liable for interest on any money received
by it except as the Trustee may agree in writing with the Company. Money held in
trust by the Trustee need not be segregated from other funds except to the
extent required by law.

         (g) Every provision of this Indenture relating to the conduct or
affecting the liability of or affording protection to the Trustee shall be
subject to the provision of this Section 7.1 and to the provisions of the TIA.

SECTION 7.2.    RIGHTS OF TRUSTEE.

         (a) Subject to Section 7.1, the Trustee may conclusively rely upon any
document believed by it to be genuine and to have been signed or presented by
the proper Person. The Trustee need not investigate any fact or matter stated in
the document.

         (b) Before the Trustee acts or refrains from acting, it may consult
with counsel and require an Officers' Certificate or an Opinion of Counsel or
both. The Trustee shall not be liable for any action it takes or omits to take
in good faith in reliance on such Officers' Certificate or Opinion of Counsel.

         (c) The Trustee may act through its attorneys and agents and shall not
be responsible for the misconduct or negligence of any agent appointed with due
care.

                                       50

<PAGE>   58

         (d) The Trustee shall not be liable for any action it takes or omits to
take in good faith that it believes in its sole subjective discretion (which
discretion shall be exercised in good faith) to be authorized or within the
rights or powers conferred upon it by this Indenture.

         (e) The permissive right of the Trustee to act hereunder shall not be
construed as a duty.

         (f) Unless otherwise specifically provided in this Indenture, any
demand, request, direction or notice from the Company shall be sufficient if
signed by an Officer of the Company.

         (g) The Trustee shall be under no obligation to exercise any of the
rights or powers vested in it by this Indenture at the request or direction of
any of the Holders unless such Holders shall have offered to the Trustee
security or indemnity satisfactory to the Trustee in its sole subjective
discretion (which discretion shall be exercised in good faith) against the
costs, expenses and liabilities that might be incurred by it in compliance with
such request or direction.

         (h) The Trustee shall not be required to take notice or deemed to have
notice of any Event of Default hereunder, except failure by the Company to make
any of the payments to the Trustee pursuant to Section 6.1(a) or Section 6.1(b)
hereof, unless the Trustee shall be specifically notified in writing of such
Event of Default by the Company or by one or more of the Holders.

SECTION 7.3.    INDIVIDUAL RIGHTS OF TRUSTEE.

         The Trustee in its individual or any other capacity may become the
owner or pledgee of Notes and may otherwise deal with the Company or any
Affiliate of the Company with the same rights it would have if it were not
Trustee. However, in the event that the Trustee acquires any conflicting
interest (as such term is defined in TIA Section 310(b)), it must eliminate such
conflict within 90 days, apply to the SEC for permission to continue as trustee
(to the extent permitted under TIA Section 310(b)) or resign. Any Agent may do
the same with like rights and duties. The Trustee is also subject to Sections
7.10 and 7.11 hereof.

SECTION 7.4.    TRUSTEE'S DISCLAIMER.

         The Trustee shall not be responsible for and makes no representation as
to the validity or adequacy of this Indenture or the Notes, it shall not be
accountable for the Company's use of the proceeds from the Notes or any money
paid to the Company or upon the Company's direction under any provision of this
Indenture, it shall not be responsible for the use or application of any money
received by any Paying Agent other than the Trustee, and it shall not be
responsible for any statement or recital herein or any statement in the Notes or
any other document in connection with the sale of the Notes or pursuant to this
Indenture other than its certificate of authentication.

                                       51


<PAGE>   59

SECTION 7.5.    NOTICE OF DEFAULTS.

         If a Default or Event of Default occurs and is continuing and if it is
actually known to the Trustee, the Trustee shall mail to Holders of Notes a
notice of the Default or Event of Default within 90 days after such event
occurs. Except in the case of a Default or Event of Default under Section 6.1(a)
or (b), the Trustee may withhold such notice if it determines that withholding
the notice is in the interests of the Holders of the Notes.

SECTION 7.6.    REPORTS BY TRUSTEE TO HOLDERS OF THE NOTES.

         Within 60 days after each May 15 beginning with the May 15 following
the date of this Indenture, and for so long as Notes remain outstanding, the
Trustee shall mail to the Holders of the Notes a brief report dated as of such
reporting date that complies with TIA Section 313(a) (but if no event described
in TIA Section 313(a) has occurred within the twelve months preceding the
reporting date, no report need be transmitted). The Trustee also shall comply
with TIA Section  313(b)(2). The Trustee shall also transmit by mail all
reports as required by TIA Section 313(c).

         A copy of each report at the time of its mailing to the Holders of
Notes shall be mailed to the Company and filed with the SEC and each stock
exchange, if any, on which the Notes are listed in accordance with and to the
extent required by TIA Section 313(d). The Company shall promptly notify the
Trustee if the Notes become listed on any stock exchange or automatic quotation
system.

SECTION 7.7.    COMPENSATION AND INDEMNITY.

         The Company shall pay to the Trustee from time to time reasonable
compensation as shall be agreed upon between the Company and the Trustee for its
acceptance of this Indenture and services hereunder, including extraordinary
services such as default administration. The Trustee's compensation shall not be
limited by any law on compensation of a trustee of an express trust. The Company
shall reimburse the Trustee promptly upon request for all reasonable
disbursements, advances and expenses incurred or made by it in addition to the
compensation for its services. Such expenses shall include the reasonable
compensation, disbursements and expenses of the Trustee's agents and counsel.

         The Company shall indemnify the Trustee against any and all losses,
liabilities or expenses incurred by it arising out of or in connection with the
acceptance or administration of its duties under this Indenture, including the
costs and expenses of enforcing this Indenture against the Company (including
this Section 7.7) and defending itself against any claim (whether asserted by
the Company or any Holder or any other Person) or liability in connection with
the exercise or performance of any of its powers or duties hereunder, except to
the extent any such loss, liability or expense may be attributable to its
negligence or bad faith. The Trustee shall promptly notify the Company of any
claim for which it may seek indemnity. The Company shall defend the claim and
the Trustee shall cooperate in the defense. The Trustee may have 


                                       52

<PAGE>   60

separate counsel and the Company shall pay the reasonable fees and expenses of
such counsel; provided that the Company will not be required to pay such fees
and expenses if it assumes the Trustee's defense with counsel acceptable to and
approved by the Trustee (such approval not to be unreasonably withheld) and
there is no conflict of interest between the Company and the Trustee in
connection with such defense. The Company need not pay for any settlement made
without its written consent, which consent shall not be unreasonably withheld.
The Company need not reimburse the Trustee for any expense or indemnity against
any liability or loss of the Trustee to the extent such expense, liability or
loss is attributable to the negligence, bad faith or willful misconduct of the
Trustee.

         The obligations of the Company under this Section 7.7 shall survive the
satisfaction and discharge of this Indenture.

         To secure the Company's payment obligations in this Section, the
Trustee shall have a Lien prior to the Notes on all money or property held or
collected by the Trustee, except that held in trust to pay principal and
interest on particular Notes. Such Lien shall survive the satisfaction and
discharge of this Indenture.

         When the Trustee incurs expenses or renders services after an Event of
Default specified in Section 6.1(g) or (h) hereof occurs, the expenses and the
compensation for the services (including the fees and expenses of its agents and
counsel) are intended to constitute expenses of administration under any
Bankruptcy Law.

         The Trustee shall comply with the provisions of TIA Section 313(b)(2).

SECTION 7.8.    REPLACEMENT OF TRUSTEE.

         A resignation or removal of the Trustee and appointment of a successor
Trustee shall become effective only upon the successor Trustee's acceptance of
appointment as provided in this Section.

         The Trustee may resign in writing upon 60 days notice and be discharged
from the trust hereby created by so notifying the Company in writing. The
Holders of Notes of a majority in principal amount of the then outstanding Notes
may remove the Trustee by so notifying the Trustee and the Company in writing
and may appoint a successor trustee with the consent of the Company. The Company
may remove the Trustee if:

                  (a) the Trustee fails to comply with Section 7.10 hereof;

                  (b) the Trustee is adjudged a bankrupt or an insolvent or an
         order for relief is entered with respect to the Trustee under any
         Bankruptcy Law;

                  (c) a receiver, Custodian or public officer takes charge of 
         the Trustee or its property; or

                  (d) the Trustee becomes incapable of acting.

         If the Trustee resigns or is removed or if a vacancy exists in the
office of Trustee for any reason, the Company shall promptly appoint or request
the Trustee to appoint a successor Trustee. Within one year after the successor
Trustee takes office, the Holders of a majority in principal amount of the then
outstanding Notes may appoint a successor Trustee to replace the successor
Trustee appointed by the Company.

         If a successor Trustee does not take office within 60 days after the
retiring Trustee resigns or is removed, the retiring Trustee, the Company, or
the Holders of Notes of at least 10% in principal amount of the then outstanding
Notes may petition any court of competent jurisdiction for the appointment of a
successor Trustee.

been a Holder of a Note for at least six months, fails to comply with Section
7.10, such Holder of a Note may petition any court of competent jurisdiction for
the removal of the Trustee and the appointment of a successor Trustee.

         A successor Trustee shall deliver a written acceptance of its
appointment to the retiring Trustee and to the Company. Thereupon, the
resignation or removal of the retiring Trustee shall become effective, and the
successor Trustee shall have all the rights, powers and duties of the Trustee
under this Indenture. The successor Trustee shall mail a notice of its
succession to Holders of the Notes. The retiring Trustee shall promptly transfer
all property held by it as Trustee to the successor Trustee, provided all sums
owing to the Trustee hereunder have been paid and subject to the Lien provided
for in Section 7.7 hereof. Notwithstanding replacement of the Trustee pursuant
to this Section 7.8, the Company's obligations under Section 7.7 hereof shall
continue for the benefit of the retiring Trustee.

SECTION 7.9.    SUCCESSOR TRUSTEE BY MERGER, ETC.

         If the Trustee consolidates, merges or converts into, or transfers all
or substantially all of its corporate trust business to, another corporation,
the successor corporation without any further act shall be the successor
Trustee.

SECTION 7.10.     ELIGIBILITY; DISQUALIFICATION.

         There shall at all times be a Trustee hereunder that is a corporation
organized and doing business under the laws of the United States of America or
of any state thereof that is authorized under such laws to exercise corporate
trustee power, that is subject to supervision or examination by federal or state

                            DEFEASANCE AND DISCHARGE

SECTION 8.1.    OPTION TO EFFECT LEGAL DEFEASANCE OR COVENANT DEFEASANCE.

         The Company may, at the option of its Board of Directors evidenced by a
resolution set forth in an Officers' Certificate, at any time, elect to have
either Section 8.2 or 8.3 hereof be applied to all outstanding Notes upon
compliance with the conditions set forth below in this Article 8.

SECTION 8.2.    LEGAL DEFEASANCE.

         Upon the Company's exercise under Section 8.1 hereof of the option
applicable to this Section 8.2, the Company shall, subject to the satisfaction
of the conditions set forth in Section 8.4 hereof, be deemed to have been
discharged from its obligations with respect to all outstanding Notes and all
obligations of the Restricted Subsidiaries under the Subsidiary Guarantees on
the date the conditions set forth below are satisfied (hereinafter, "Legal
Defeasance"). For this purpose, Legal Defeasance means that the Company shall be
deemed to have paid and discharged the entire Indebtedness represented by the
outstanding Notes, which shall thereafter be deemed to be "outstanding" only for
the purposes of Section 8.6 hereof and the other Sections of this Indenture
referred to in (a) and (b) below, and to have satisfied all its other
obligations under such Notes and this Indenture (and the Trustee, on demand of
and at the expense of the Company, shall execute proper instruments
acknowledging the same), except for the following provisions which shall survive
until otherwise terminated or discharged pursuant to this Indenture: (a) the
rights of Holders of outstanding Notes to receive solely from the trust fund
described in Section 8.4 hereof, and as more fully set forth in such Section,
payments in respect of the principal of and premium, if any, and interest on
such Notes when such payments are due, (b) the Company's obligations with
respect to such Notes under Sections 2.3, 2.4, 2.6, 2.7, 2.10 and 4.2 hereof,
(c) the rights, powers, trusts, duties and immunities of the Trustee hereunder
and the Company's obligations in connection therewith and (d) Sections 3.1

8, the Company may exercise its option under this Section 8.2 notwithstanding
the prior exercise of its option under Section 8.3 hereof.

SECTION 8.3.    COVENANT DEFEASANCE.

         Upon the Company's exercise under Section 8.1 hereof of the option
applicable to this Section 8.3, and subject to the satisfaction of the
conditions set forth in Section 8.4 hereof, the Company and the Subsidiary
Guarantors shall be released from their obligations under the covenants
contained in Sections 4.3, 4.4, 4.5, 4.7, 4.8, 4.9, 4.10, 4.11, 4.12, 4.13,
4.14, 4.15, 4.16, 4.17, 4.18, 5.1 and 5.2 and Articles 10 and 11 with respect to
the outstanding Notes on and after the date the conditions set forth below are
satisfied (hereinafter, "Covenant Defeasance"), and the Notes shall thereafter
be deemed not "outstanding" for the purposes of any direction, waiver, consent
or declaration or act of Holders (and the consequences of any thereof) in
connection with such covenants, but shall continue to be deemed "outstanding"
for all other purposes hereunder (it being understood that such Notes shall not
be deemed outstanding for accounting purposes). For this purpose, Covenant
Defeasance means that, with respect to the outstanding Notes, the Company may
omit to comply with and shall have no liability in respect of any term,
condition or limitation set forth in any such covenant, whether directly or
indirectly, by reason of any reference elsewhere herein to any such covenant or
by reason of any reference in any such covenant to any other provision herein or
in any other document and such omission to comply shall not constitute a Default
or an Event of Default under Section 6.1 hereof, but, except as specified above,
the remainder of this Indenture and such Notes shall be unaffected thereby. In
addition, upon the Company's exercise under Section 8.1 hereof of the option
applicable to this Section 8.3 hereof, subject to the satisfaction of the
conditions set forth in Section 8.4 hereof, Sections 6.1(e), 6.1(f), 6.1(i) and
6.1(j) hereof shall not constitute Events of Default.

SECTION 8.4.    CONDITIONS TO LEGAL OR COVENANT DEFEASANCE.

         The following shall be the conditions to application of either Section
8.2 or Section 8.3 to the outstanding Notes:

         (a) The Company must irrevocably deposit, or caused to be deposited,
with the Trustee (or another trustee satisfying the requirements of this
Indenture), in trust for such purpose, specifically pledged as security for the
benefit of the Holders of the Notes, (1) cash in U.S. dollars in an amount, (2)
non-callable Government Securities which through the payment of principal and
interest in accordance with their terms will provide money in an amount, or (3)
a combination thereof, in such amounts, as will be sufficient, without
reinvestment (and without other assets, including without limitation, the
Pledged Securities and other assets held pursuant to the Pledge Agreement), in
the opinion of a nationally recognized firm of independent public accountants
expressed in a written certification thereof delivered to the Trustee, to pay
the principal of and premium, if any, and interest on the outstanding Notes on
the stated maturity or on the applicable redemption date, as the case may be,
together with all other amounts payable by the Company under this Indenture.

         (b) In the case of an election under Section 8.2, the Company shall
have delivered to the Trustee an Opinion of Counsel in the United States
reasonably acceptable to the 

                                       56

<PAGE>   64

Trustee confirming that (i) the Company has received from, or there has been
published by, the Internal Revenue Service a ruling or (ii) since the date
hereof, there has been a change in the applicable federal income tax law, in
either case to the effect that, and based thereon such Opinion of Counsel shall
confirm that, the Holders of the outstanding Notes will not recognize income,
gain or loss for federal income tax purposes as a result of such Legal
Defeasance and will be subject to federal income tax on the same amounts, in the
same manner and at the same times as would have been the case if such Legal
Defeasance had not occurred.

         (c) In the case of an election under Section 8.3, the Company shall
have delivered to the Trustee an Opinion of Counsel in the United States
reasonably acceptable to the Trustee confirming that the Holders of the
outstanding Notes will not recognize income, gain or loss for federal income tax
purposes as a result of such Covenant Defeasance and will be subject to federal
income tax on the same amounts, in the same manner and at the same times as
would have been the case if such Covenant Defeasance had not occurred.

         (d) No Default or Event of Default shall have occurred and be
continuing on the date of such deposit or insofar as Sections 6.1(g) and (h) are
concerned, at any time in the period ending on the 91st day after the date of
deposit (it being understood that this condition shall not be deemed satisfied
until the expiration of such period).

         (e) Such Legal Defeasance or Covenant Defeasance will not result in a
breach or violation of, or constitute a default under any material agreement or
instrument to which the Company or any of its Subsidiaries is a party or by
which the Company or any of its Subsidiaries is bound.

         (f) The Company shall have delivered to the Trustee an Officers'
Certificate stating that the deposit was not made by the Company with the intent
of preferring the Holders of Notes over the other creditors of the Company with
the intent of defeating, hindering, delaying or defrauding creditors of the
Company or others.

         (g) The Company shall have delivered to the Trustee an Officers'
Certificate and an Opinion of Counsel, each stating that all conditions
precedent provided for relating to either the Legal Defeasance under Section 8.2
or the Covenant Defeasance under Section 8.3, as the case may be, have been
complied with as contemplated by this Section 8.4.

SECTION 8.5.      DISCHARGE.

         This Indenture will be discharged and will cease to be of further
effect (except as to surviving rights of registration of transfer or exchange of
Notes) as to all outstanding Notes ("Discharge") when (i) either (a) all such
Notes theretofore authenticated and delivered (except lost, stolen or destroyed
Notes that have been replaced or paid and Notes for whose payment money has
theretofore been deposited in trust with the Trustee and thereafter repaid to
the Company or discharged from such trust) have been delivered to the Trustee
for cancellation; or (b) all such Notes not theretofore delivered to the Trustee
for cancellation have become due and 


                                       57

<PAGE>   65

payable, will become due and payable by their terms within one year, or are to
be called for redemption within one year under arrangements satisfactory to the
Trustee for the giving of notice of redemption, and in each case the Company has
irrevocably deposited or caused to be deposited with the Trustee, as trust funds
solely for the benefit of the Holders for that purpose, funds in an amount of
money in U.S. dollars sufficient to pay and discharge the entire indebtedness on
the Notes not theretofore delivered to the Trustee for cancellation, for the
principal amount, premium, if any, and accrued and unpaid interest to the date
of such deposit together with irrevocable instructions from the Company
directing the Trustee to apply such funds to the payment thereof; (ii) the
Company has paid all other sums payable by it under this Indenture; and (iii)
the Company has delivered irrevocable instructions to the Trustee to apply the
deposited money toward the payment of the Notes at maturity, as the case may be.
In addition, the Company must deliver an Officers' Certificate and an Opinion of
Counsel stating that all conditions precedent under this Indenture to
satisfaction and discharge have been complied with.

SECTION 8.6. DEPOSITED MONEY AND GOVERNMENT SECURITIES TO BE HELD IN TRUST; 
OTHER MISCELLANEOUS PROVISIONS.

         Subject to Section 8.7 hereof, all money and Government Securities
(including the proceeds thereof) deposited with the Trustee (or other qualifying
trustee, collectively for purposes of this Section 8.6, the "Trustee") pursuant
to Section 8.4 or 8.5 hereof in respect of the outstanding Notes shall be held
in trust and applied by the Trustee, in accordance with the provisions of such
Notes and this Indenture, to the payment, either directly or through any Paying
Agent (including the Company or any of its Subsidiaries or Affiliates acting as
Paying Agent) as the Trustee may determine, to the Holders of such Notes of all
sums due and to become due thereon in respect of principal, premium, if any, and
interest, but such money need not be segregated from other funds except to the
extent required by law.

         The Company shall pay and indemnify the Trustee against any tax, fee or
other charge imposed on or assessed against the cash or Government Securities
deposited pursuant to this Section 8.6 or the principal and interest received in
respect thereof other than any such tax, fee or other charge which by law is for
the account of the Holders of the outstanding Notes.

         Anything in this Article 8 to the contrary notwithstanding, the Trustee
shall deliver or pay to the Company from time to time upon the request of the
Company any money or Government Securities held by it as provided in this
Section 8.6 which, in the opinion of a nationally recognized firm of independent
public accountants expressed in a written certification thereof delivered to the
Trustee (which may be the opinion delivered under Section 8.4 hereof), are in
excess of the amount thereof that would then be required to be deposited to
effect an equivalent Legal Defeasance, Covenant Defeasance or Discharge.

<PAGE>   66

SECTION 8.7.    REPAYMENT TO COMPANY.

         Any money deposited with the Trustee or any Paying Agent, or then held
by the Company or any of its Subsidiaries or Affiliates, in trust for the
payment of the principal of, premium, if any, or interest on any Note and
remaining unclaimed for one year after such principal, premium, if any, or
interest has become due and payable shall be paid to the Company on its request
or (if then held by the Company or any of its Subsidiaries or Affiliates) shall
be discharged from such trust; and the Holder of such Note shall thereafter, as
an unsecured general creditor, look only to the Company for payment thereof, and
all liability of the Trustee or such Paying Agent with respect to such trust
money, and all liability of the Company or any of its Subsidiaries or Affiliates
as trustee thereof, shall thereupon cease.

SECTION 8.8.    REINSTATEMENT.

         If the Trustee or Paying Agent is unable to apply any U.S. dollars or
Government Securities in accordance with Section 8.2, 8.3 or 8.5 hereof, as the
case may be, by reason of any order or judgment of any court or governmental
authority enjoining, restraining or otherwise prohibiting such application, then
the Company's obligations under this Indenture and the Notes shall be revived
and reinstated as though no deposit had occurred pursuant to Section 8.2, 8.3 or
8.5 hereof until such time as the Trustee or Paying Agent is permitted to apply
all such assets in accordance with Section 8.2, 8.3 or 8.5 hereof, as the case
may be; provided, however, that, if the Company makes any payment of principal
of, premium, if any, or interest on any Note following the reinstatement of its
obligations, the Company shall be subrogated to the rights of the Holders of
such Notes to receive such payment from the money held by the Trustee or Paying
Agent.

                        AMENDMENT, SUPPLEMENT AND WAIVER

SECTION 9.1.    WITHOUT CONSENT OF HOLDERS OF NOTES.

         Notwithstanding Section 9.2 of this Indenture, the Company, the
Subsidiary Guarantors and the Trustee may amend or supplement this Indenture,
the Notes or the Pledge Agreement without the consent of any Holder:

         (a) to cure any ambiguity, defect or inconsistency;

         (b) to provide for uncertificated Notes in addition to or in place of
certificated Notes;

         (c) to provide for the assumption of the Company's obligations to the
Holders of Notes in the case of a merger or consolidation pursuant to Article 5
hereof;


                                       59


<PAGE>   67

         (d) to make any change that would provide any additional rights or
benefits to the Holders of the Notes or that does not adversely affect the legal
rights hereunder of any such Holder;

         (e) to add a Subsidiary Guarantor pursuant to the provisions set forth
in this Indenture; or

         (f) to comply with requirements of the SEC in order to effect or
maintain the qualification of this Indenture under the TIA as then in effect.

         Upon the request of the Company and the Subsidiary Guarantors,
accompanied by a Board Resolution of the Company and each Subsidiary Guarantor
authorizing the execution of any such amended or supplemental Indenture, and
upon receipt by the Trustee of the documents described in Section 7.2 hereof,
the Trustee shall join with the Company and the Subsidiary Guarantors in the
execution of any amended or supplemental Indenture authorized or permitted by
the terms of this Indenture and to make any further appropriate agreements and
stipulations that may be therein contained. After an amendment or supplement
under this Section 9.1 becomes effective, the Company shall mail to the Holders
of Notes a notice briefly describing the amendment or supplement. Any failure of
the Company to mail such notice, or any defect therein, shall not, however, in
any way impair or affect the validity of any such amended or supplemental
Indenture.

SECTION 9.2.    WITH CONSENT OF HOLDERS OF NOTES.

         Except as provided below in this Section 9.2, this Indenture, the Notes
or the Pledge Agreement may be amended or supplemented with the consent of the
Holders of at least a majority in principal amount of the Notes then outstanding
(including, without limitation, consents obtained in connection with a purchase
of, or tender offer or exchange offer for, Notes), and, subject to Sections 6.4
and 6.7, any existing Default or Event of Default (other than a Default or Event
of Default in the payment of principal of, premium, if any, or interest on, the
Notes, except a payment default resulting from an acceleration that has been
rescinded) or compliance with any provision of this Indenture or the Notes may
be waived with the consent of the Holders of a majority in principal amount of
the then outstanding Notes (including consents obtained in connection with a
purchase of, or tender offer or exchange offer for, Notes).

         Upon the request of the Company and the Subsidiary Guarantors,
accompanied by a Board Resolution of the Company and each Subsidiary Guarantor
authorizing the execution of any such amended or supplemental Indenture, and
upon the filing with the Trustee of evidence satisfactory to the Trustee of the
consent of the Holders of Notes as aforesaid, and upon receipt by the Trustee of
the documents described in Section 7.2 hereof, the Trustee shall join with the
Company and the Subsidiary Guarantors in the execution of such amended or
supplemental Indenture and to make any further appropriate agreements and
stipulations that may be therein contained, but the Trustee shall not be
obligated to enter into such amended or supplemental 

                                       60

<PAGE>   68

Indenture that adversely affects its own rights, duties, liabilities or
immunities under this Indenture or otherwise.

         It shall not be necessary for the consent of the Holders of Notes under
this Section 9.2 to approve the particular form of any proposed amendment or
waiver, but it shall be sufficient if such consent approves the substance
thereof.

         After an amendment, supplement or waiver under this Section 9.2 becomes
effective, the Company shall mail to the Holders of Notes a notice briefly
describing the amendment, supplement or waiver. Any failure of the Company to
mail such notice, or any defect therein, shall not, however, in any way impair
or affect the validity of any such amended or supplemental Indenture or waiver.
Subject to Sections 6.4 and 6.7 hereof, the Holders of a majority in principal
amount of the Notes then outstanding may waive compliance in a particular
instance by the Company with any provision of this Indenture, the Notes or the
Pledge Agreement. However, without the consent of each Holder affected, an
amendment or waiver may not (with respect to any Notes held by a non-consenting
Holder):

         (a) reduce the principal amount of Notes whose Holders must consent to
an amendment, supplement or waiver;

         (b) reduce the principal of or change the fixed maturity of any Note or
alter the provisions with respect to the redemption of the Notes (other than the
provisions relating to Section 4.14);

         (c) reduce the rate of or change the time for payment of interest on
any Note;

         (d) waive a Default or Event of Default in the payment of principal of,
premium, if any, or interest on the Notes (except a rescission of acceleration
of the Notes by the Holders of at least a majority in aggregate principal amount
of the Notes and a waiver of the payment default that resulted from such
acceleration);

         (e) make any Note payable in money other than that stated in the Notes;

         (f) make any change in the provisions of this Indenture relating to
waivers of past Defaults or the rights of Holders of Notes to receive payments
of principal of, premium, if any, or interest on the Notes;

         (g) waive a redemption payment with respect to any Note (other than a
payment required by Section 4.14);

         (h) release any Collateral from the Lien created by the Pledge
Agreement, except in accordance with the terms thereof, or amend the terms
thereof relating to the release of Collateral;

                                       61


<PAGE>   69

         (i) release any Subsidiary Guarantor from its Subsidiary Guarantee
except as permitted hereunder;

         (j) make any change in the provisions of this Indenture requiring any
Guarantee hereof or in the provisions of any such Guarantees; or

         (k) make any change in the foregoing amendment and waiver provisions.

SECTION 9.3.    COMPLIANCE WITH TRUST INDENTURE ACT.

         Every amendment or supplement to this Indenture or the Notes shall be
set forth in an amended or supplemental Indenture that complies with the TIA as
then in effect.

SECTION 9.4.    REVOCATION AND EFFECT OF CONSENTS.

         Until an amendment, supplement or waiver becomes effective, a consent
to it by a Holder of a Note is a continuing consent by the Holder of a Note and
every subsequent Holder of a Note or portion of a Note that evidences the same
debt as the consenting Holder's Note, even if notation of the consent is not
made on any Note. However, any such Holder of a Note or subsequent Holder of a
Note may revoke the consent as to its Note if the Trustee receives written
notice of revocation before the date the waiver, supplement or amendment has
been approved by the requisite Holders. An amendment, supplement or waiver
becomes effective when approved by the requisite Holders and executed by the
Trustee (or, if otherwise provided in such waiver, supplement or amendment, in
accordance with its terms) and thereafter binds every Holder.

         The Company may, but shall not be obligated to, fix a record date for
the purpose of determining the Holders entitled to consent to any amendment,
supplement or waiver. If a record date is fixed, then notwithstanding the last
sentence of the immediately preceding paragraph, those Persons who were Holders
at such record date (or their duly designated proxies), and only those Persons,
shall be entitled to consent to such amendment or waiver or revoke any consent
previously given, whether or not such Persons continue to be Holders after such
record date. No consent shall be valid or effective for more than 90 days after
such record date except to the extent that the requisite number of consents to
the amendment, supplement or waiver have been obtained within such 90-day period
or as set forth in the next paragraph of this Section 9.4.

         After an amendment, supplement or waiver becomes effective, it shall
bind every Holder, unless it makes a change described in any of clauses (a)
through (k) of Section 9.2, in which case, the amendment, supplement or waiver
shall bind only each Holder of a Note who has consented to it and every
subsequent Holder of a Note or portion of a Note that evidences the same
indebtedness as the consenting Holder's Note.

<PAGE>   70

SECTION 9.5.    NOTATION ON OR EXCHANGE OF NOTES.

         The Trustee may place an appropriate notation about an amendment,
supplement or waiver on any Note thereafter authenticated. The Company in
exchange for all Notes may issue, and the Trustee shall authenticate, new Notes
that reflect the amendment, supplement or waiver.

         Failure to make the appropriate notation or issue a new Note shall not
affect the validity and effect of such amendment, supplement or waiver.

SECTION 9.6.    TRUSTEE TO SIGN AMENDMENTS, ETC.

         The Trustee shall sign any amended or supplemental Indenture authorized
pursuant to this Article 9 if the amendment or supplement does not adversely
affect the rights, duties, liabilities or immunities of the Trustee. In
executing any amended or supplemental indenture, the Trustee shall be entitled
to receive and (subject to Section 7.1) shall be fully protected in relying
upon, an Officers' Certificate and an Opinion of Counsel stating that the
execution of such amended or supplemental indenture is authorized or permitted
by this Indenture.

SECTION 9.7.    PAYMENTS FOR CONSENT.

         The Company will not, and will not permit any of its Restricted
Subsidiaries to, directly or indirectly, pay or cause to be paid any
consideration, whether by way of interest, fee or otherwise, to any Holder of
any Notes for or as an inducement to any consent, waiver or amendment of any
terms or provisions of this Indenture, the Notes, the Pledge Agreement or the
Subsidiary Guarantees unless such consideration is offered to be paid or is paid
to all Holders of the Notes that so consent, waive or agree to amend in the time
frame set forth in solicitation documents relating to such consent, waiver or
agreement.


                                   ARTICLE 10

                              SUBSIDIARY GUARANTEES

SECTION 10.1.     GUARANTEES.

         Each Subsidiary Guarantor hereby, jointly and severally,
unconditionally and irrevocably guarantees, to each Holder and to the Trustee
and its successors and assigns the due and punctual payment of principal of,
premium, if any, and interest on the Notes and all other amounts due and payable
under this Indenture and the Notes by the Company whether at maturity, by
acceleration, redemption, repurchase or otherwise, including, without
limitation, interest on the overdue principal of, premium, if any, and interest
on the Notes, to the extent lawful, all in accordance with the terms hereof and
thereof.

         Each Subsidiary Guarantor waives presentation to, demand of, payment
from and protest to the Company of any of the obligations contained in the Notes
and this Indenture and also waives notice of protest for nonpayment, notice of
intent to accelerate and notice of acceleration. Each Subsidiary Guarantor
waives notice of any default under the Notes or the obligations guaranteed
hereby. The obligations of each Subsidiary Guarantor hereunder shall not be
affected by (a) the failure of any Holder or the Trustee to assert any claim or
demand or to enforce any right or remedy against the Company or any other Person
under this Indenture, the Notes or any other agreement or otherwise; (b) any
extension or renewal of any thereof; (c) any rescission, waiver, amendment or
modification of any of the terms or provisions of this Indenture, the Notes
or any other agreement; (d) the release of any security held by any Holder or
the Trustee for the obligations guaranteed hereby or any of them; (e) the
failure of any Holder or the Trustee to exercise any right or remedy against any
other guarantor of the obligations guaranteed hereby; or (f) any change in the
ownership of such Subsidiary Guarantor.

         Each Subsidiary Guarantor further agrees that its Subsidiary Guarantee
herein constitutes a guarantee of payment, performance and compliance when due
(and not a guarantee of collection) and waives any right to require that any
resort be had by any Holder or the Trustee to any security held for payment of
the obligations guaranteed hereby.

         Except as expressly set forth in Sections 8.2, 8.3, 10.3 and 10.7, the
obligations of each Subsidiary Guarantor hereunder shall not be subject to any
reduction, limitation, impairment or termination for any reason, including any
claim of waiver, release, surrender, alteration or compromise, and shall not be
subject to any defense of setoff, counterclaim, recoupment or termination
whatsoever or by reason of the invalidity, illegality or unenforceability of the
obligations guaranteed hereby or otherwise. Without limiting the generality of
the foregoing, the obligations of each Subsidiary Guarantor herein shall not be
discharged or impaired or otherwise affected by the failure of any Holder or the
Trustee to assert any claim or demand or to enforce any remedy under this
Indenture, the Notes or any other agreement, by any waiver or modification of
any thereof, by any default, failure or delay, willful or otherwise, in the
performance of the obligations guaranteed hereby, or by any other act or thing
or omission or delay to do any other act or thing which may or might in any
manner or to any extent vary the risk of such Subsidiary Guarantor or would
otherwise operate as a discharge of such Subsidiary Guarantor as a matter of law
or equity.

         Each Subsidiary Guarantor further agrees that its Subsidiary Guarantee
herein shall continue to be effective or be reinstated, as the case may be, if
at any time payment, or any part thereof, of principal of, premium, if any, or
interest on any obligation guaranteed hereby is rescinded or must otherwise be
restored by any Holder or the Trustee upon the bankruptcy or reorganization of
the Company or otherwise.

         In furtherance of the foregoing and not in limitation of any other
right which any Holder or the Trustee has at law or in equity against any
Subsidiary Guarantor by virtue hereof, upon the failure of the Company to pay
the principal of, premium, if any, or interest on any obligation guaranteed
hereby when and as the same shall become due, whether at maturity, by


                                       64

acceleration, by redemption or otherwise, or to perform or comply with any other
obligation guaranteed hereby, each Subsidiary Guarantor hereby promises to and
will, upon receipt of written demand by the Trustee, forthwith pay, or cause to
be paid, in cash, to the Holders or the Trustee an amount equal to the sum of
(i) the unpaid amount of such obligations, (ii) accrued and unpaid interest on
such obligations (but only to the extent not prohibited by law) and (iii) all
other monetary obligations of the Company to the Holders and the Trustee.

         Each Subsidiary Guarantor agrees that it shall not be entitled to any
right of subrogation in respect of any obligations guaranteed hereby until
payment in full of all such obligations. Each Subsidiary Guarantor further
agrees that, as between it, on the one hand, and the Holders and the Trustee, on
the other hand, (x) the maturity of the obligations guaranteed hereby may be
accelerated as provided in Article 6 for the purposes of such Subsidiary
Guarantor's Subsidiary Guarantee herein, notwithstanding any stay, injunction or
other prohibition preventing such acceleration in respect of the obligations
guaranteed hereby, and (y) in the event of any declaration of acceleration of
such obligations as provided in Article 6, such obligations (whether or not due
and payable) shall forthwith become due and payable by such Subsidiary Guarantor
for the purposes of this Section.

         Each Subsidiary Guarantor also agrees to pay any and all costs and
expenses (including reasonable attorneys' fees) incurred by the Trustee or any
Holder in enforcing any rights under this Section.

SECTION 10.2.     SUBSIDIARY GUARANTORS MAY CONSOLIDATE, ETC., ON CERTAIN TERMS.

         (a) Subject to paragraph (b) of this Section 10.2, no Restricted
Subsidiary may consolidate or merge with or into (whether or not such Restricted
Subsidiary is the surviving Person), or sell, assign, transfer, lease, convey or
otherwise dispose of all or substantially all of its properties or assets in one
or more related transactions, to another Person unless (i) the Person formed by
or surviving any such consolidation or merger (if other than such Restricted
Subsidiary) or the Person to which such sale, assignment, transfer, lease,
conveyance or other disposition shall have been made assumes all the obligations
of such Restricted Subsidiary under the Subsidiary Guarantee, pursuant to a
supplemental indenture in form satisfactory to the Trustee; (ii) immediately
after such transaction, no Default or Event of Default exists; (iii) the Company
and its Restricted Subsidiaries would, at the time of such transaction and after
giving pro forma effect thereto as if such transaction had occurred at the
beginning of the applicable fiscal quarter, be permitted to Incur at least $1.00
of additional Indebtedness pursuant to the Consolidated Interest Coverage Ratio
test set forth in Section 4.9(a); (iv) the Company shall have delivered to the
Trustee an Officers' Certificate and an Opinion of Counsel, each stating that
such consolidation, merger or transfer complies with the provisions of this
Indenture; and (v) such Restricted Subsidiary (if such Restricted Subsidiary is
the surviving Person) shall have delivered a written instrument in form
satisfactory to the Trustee confirming its Subsidiary Guarantee after giving
effect to such consolidation, merger or transfer. Notwithstanding the foregoing,
any Restricted Subsidiary may merge into, consolidate with or transfer all or
part of its properties or assets to the Company or one or more Restricted
Subsidiaries.

         (b) In the event of a sale, assignment, transfer, lease, conveyance or
other disposition of all of the Equity Interests in, or all or substantially all
of the assets of, a Restricted Subsidiary to any Person that is not the Company
or any of its Restricted Subsidiaries, whether by way of merger, consolidation
or otherwise, if (i) the Net Proceeds of such sale or other disposition are
applied in accordance with the provisions of Section 4.10, (ii) no Default or
Event of Default exists or would exist under this Indenture after giving effect
to such transaction, (iii) all obligations of such Restricted Subsidiary under
any other Indebtedness of the Company or any of its Restricted Subsidiaries
shall have been terminated (including, without limitation, all Guarantees of any
such Indebtedness), (iv) all Liens on assets of such Restricted Subsidiary that
secure any other Indebtedness of the Company or any of its Restricted
Subsidiaries shall have been terminated, and (v) all obligations of the Company
and its Restricted Subsidiaries under other Indebtedness of such Restricted
Subsidiary shall have been terminated (including, without limitation, all
Guarantees of such Indebtedness), then (A) in the case of such a sale or other
disposition, whether by way of merger, consolidation or otherwise, of all of the
Equity Interests in such former Restricted Subsidiary, such former Restricted
Subsidiary will be released and relieved of any obligations under its Subsidiary
Guarantee, or (B) in the case of a sale or other disposition of all or
substantially all of the assets of such Restricted Subsidiary, the Person
acquiring such assets will not be required to assume the obligations of such
Restricted Subsidiary under its Subsidiary Guarantee.

SECTION 10.3.     LIMITATION ON LIABILITY.

         Any term or provision of this Indenture to the contrary
notwithstanding, the maximum aggregate amount of the obligations guaranteed
hereunder by any Subsidiary Guarantor shall not exceed the maximum amount that
can be hereby guaranteed without rendering this Indenture, as it relates to such
Subsidiary Guarantor, voidable under applicable law relating to fraudulent
conveyance or fraudulent transfer or similar laws affecting the rights of
creditors generally. To effectuate the foregoing intention, the obligations of
each Subsidiary Guarantor shall be limited to the maximum amount as will, after
giving effect to all other contingent and fixed liabilities of such Subsidiary
Guarantor and after giving effect to any collections from, rights to receive
contributions from, or payments made by or on behalf of any other Subsidiary
Guarantor in respect of the obligations of such other Subsidiary Guarantor under
its Subsidiary Guarantee or pursuant to its contribution obligations hereunder,
result in the obligations of such Subsidiary Guarantor under its Subsidiary
Guarantee not constituting a fraudulent conveyance or fraudulent transfer under
any Applicable Law. Each Subsidiary Guarantor that makes a payment or
distribution under a Subsidiary Guarantee shall be entitled to a contribution
from each other Subsidiary Guarantor so long as the exercise of such right does
not impair the rights of the Holders under the Subsidiary Guarantees.

assigns of the Trustee and the Holders and, in the event of any transfer or
assignment of rights by any Holder or the Trustee, the rights and privileges
conferred upon that party in this Indenture and in the Notes shall automatically
extend to and be vested in such transferee or assignee, all subject to the terms
and conditions of this Indenture.

SECTION 10.5.     NO WAIVER.

         Neither a failure nor a delay on the part of either the Trustee or the
Holders in exercising any right, power or privilege under this Article 10 shall
operate as a waiver thereof, nor shall a single or partial exercise thereof
preclude any other or further exercise of any right, power or privilege. The
rights, remedies and benefits of the Trustee and the Holders herein expressly
specified are cumulative and not exclusive of any other rights, remedies or
benefits which either may have under this Article 10 at law, in equity, by
statute or otherwise.

SECTION 10.6.     MODIFICATION.

         No modification, amendment or waiver of any provision of this Article
10, nor the consent to any departure by any Subsidiary Guarantor therefrom,
shall in any event be effective unless the same shall be in writing and signed
by the Trustee, and then such waiver or consent shall be effective only in the
specific instance and for the purpose for which given. No notice to or demand on
any Subsidiary Guarantor in any case shall entitle such Subsidiary Guarantor to
any other or further notice or demand in the same, similar or other
circumstances.

Indenture, including, but not limited to the provisions of Section 10.2, such

SUBSIDIARIES.

after the Closing Date (including any Subsidiary that was previously an
Unrestricted Subsidiary and which becomes a Restricted Subsidiary) to promptly
execute and deliver to the Trustee a supplemental indenture pursuant to which
such Restricted Subsidiary shall become a Subsidiary Guarantor under this
Article 10 and shall guarantee the Notes pursuant to the terms hereof.

such supplemental indenture has been duly authorized, executed and delivered by
such Restricted Subsidiary and that, subject to the application of bankruptcy,
insolvency, moratorium, fraudulent conveyance or transfer and other similar laws
relating to creditors' rights generally and to the principles of equity, whether

security interest in the Collateral or for filing any instrument, document or
notice in any public office at any time or times.

such action or referring to prior Opinions of Counsel in which such details are
given and (B) based on relevant laws as in effect on the date of such Opinion of
Counsel, all financing statements and continuation statements have been executed

automatically released by operation of Section 9-306 of the Uniform Commercial
Code or other similar law, no Collateral shall be released from the Lien created
by the Pledge Agreement pursuant to the provisions of the Pledge Agreement,
other than to the Holders pursuant to the terms thereof, unless there shall have
been delivered to the Trustee the certificates, if any, required by Section
11.3(d) and Section 11.4.

provisions of the Pledge Agreement, and no release of Collateral in
contravention of this Section 11.3(c) shall be effective as against the Holders
of the Notes, except for the disbursement of all Available Funds (as defined in
the Pledge Agreement) to the Trustee pursuant to Section 6(b)(iii) of the Pledge
Agreement.

         (d) On or before each of the first two Interest Payment Dates, if the
conditions set forth in Sections 3.2(a) and 3.2(c) of the Pledge Agreement have
been satisfied, then the Pledge Agent under the Pledge Agreement may release
Collateral from the Liens created by this Indenture and the Pledge Agreement
and apply such funds as required by Section 4.1 of this Indenture. Any such
release of Collateral shall not be deemed to impair the security under this
Indenture in contravention of the provisions hereof. To the extent applicable,
the Company shall cause TIA Section 314(d) relating to the release of property
or securities from the Lien and security interest of the Pledge Agreement to be
complied with. Any certificate or opinion required by TIA Section 314(d) may be

selected or approved by the Trustee in the exercise of reasonable care.

of the Notes, take all actions it deems necessary or appropriate in order to (a)
enforce any of the terms of the Pledge Agreement and (b) collect and receive any

Agreement or this Indenture, and such suits and proceedings as the Trustee may
deem expedient to preserve or protect its interests and the interests of the
Holders of the Notes in the Collateral (including power to institute and
maintain suits or proceedings to restrain the enforcement of or compliance with

                         (Form of Reverse Side of Note)

                            11% Senior Notes due 2008


         Capitalized terms used herein but not defined shall have the meanings
assigned to them in the Indenture referred to below unless otherwise indicated.

         1. INTEREST. The Notes will be limited in aggregate principal amount to
$90 million (except as otherwise provided in Section 2.7 of the Indenture
referred to below) and will mature on February 1, 2008. The Company promises to
pay interest on the principal amount of this Note from the Closing Date until
maturity. The Company will pay interest semi-annually on February 1 and August 1
of each year, commencing August 1, 1998, or if any such day is not a Business
Day, on the next succeeding Business Day (each an "Interest Payment Date") to
Holders of record on the immediately preceding January 15 and July 15, as
appropriate (each, a "Record Date"). Interest on the Notes will accrue at the
rate of 11% per annum from the most recent date to which interest has been paid
or, if no interest has been paid, from the Closing Date. The Company shall pay
interest (including post-petition interest in any proceeding under any
Bankruptcy Law to the extent that such interest is an allowed claim enforceable
against the debtor under such Bankruptcy Law) on overdue principal and premium,
if any, from time to time on demand at the rate equal to 1% per annum in excess
of the rate then in effect; it shall pay interest (including post-petition
interest in any proceeding under any Bankruptcy Law) on overdue installments of
interest (without regard to any applicable grace periods) from time to time on
demand at the same rate to the extent lawful. Interest will be computed on the
basis of a 360-day year of twelve 30-day months.

         2. METHOD OF PAYMENT. The Company shall pay the principal of, and
premium, and interest on, the Notes on the dates and in the manner provided
herein and in the Indenture. Principal of, and premium, and interest on,
Certificated Notes will be payable, and Certificated Notes may be presented for
registration of transfer or exchange, at the office or agency of the Company
maintained for such purpose. Principal of, and premium, and interest on, Global
Notes will be payable by the Company through the Trustee to the Depositary by
wire transfer of immediately available funds. Holders of Certificated Notes will
be entitled to receive interest payments by wire transfer in immediately
available funds if appropriate wire transfer instructions have been received in
writing by the Trustee not less than 15 days prior to the applicable Interest
Payment Date. Such wire instructions, upon receipt by the Trustee, shall remain
in effect until revoked by such Holder. If wire instructions have not been
received by the Trustee with respect to any Holder of a Certificated Note,
payment of interest may be made by check in immediately available funds mailed
to such Holder at the address set forth upon the Register maintained by the
Registrar.

         3. PAYING AGENT AND REGISTRAR.  Initially, Bank One, N.A., the Trustee
under the Indenture, will act as Paying Agent and Registrar. The Company may
change any Paying Agent or Registrar without notice to any Holder. The Company
or any of its Subsidiaries may act in

                                      A-3

<PAGE>   88

any such capacity, except that none of the Company, its Subsidiaries or their
Affiliates shall act (i) as Paying Agent in connection with any redemption,
offer to purchase, discharge or defeasance, as otherwise specified in the
Indenture, and (ii) as Paying Agent or Registrar if a Default or Event of
Default has occurred and is continuing.

         4.       INDENTURE.

                  The Company issued the Notes under an Indenture dated as of
February 2, 1998 (as such may be amended, supplemented or restated from time to
time, the "Indenture") by and among the Company, the Initial Subsidiary
Guarantors named therein, and the Trustee. The terms of the Notes include those
stated in the Indenture and those made part of the Indenture by reference to the
Trust Indenture Act of 1939, as amended (15 U.S. Code Sections 77aaa-77bbbb).
The Notes are subject to all such terms, and Holders are referred to the
Indenture and such Act for a statement of such terms. The Notes are senior
obligations of the Company limited to $90 million in aggregate principal amount
(except as otherwise provided in Section 2.7 of the Indenture).

                  Each of the Initial Subsidiary Guarantors will Guarantee the
Notes, and the Indenture requires the Company to cause any other Person that
becomes a Restricted Subsidiary after the Closing Date to execute and deliver to
the Trustee a supplemental indenture pursuant to which such Restricted
Subsidiary will Guarantee the Notes. So long as no Default or Event of Default
exists or would be caused thereby, any Person that is no longer a Restricted
Subsidiary may, by execution and delivery to the Trustee of a supplemental
indenture satisfactory to the Trustee, be released from its Subsidiary Guarantee
and cease to Guarantee the Notes.

                  The Indenture contains certain covenants that, among other
things, limit the ability of the Company and its Restricted Subsidiaries to
incur additional Indebtedness, pay dividends or make other distributions,
repurchase any capital stock or Subordinated Indebtedness, make certain
investments, create certain liens, enter into certain transactions with
affiliates, sell assets, enter into certain mergers and consolidations, allow
Restricted Subsidiaries to create certain dividend and other payment
restrictions, enter into sale and leaseback transactions, and issue or sell
capital stock of Restricted Subsidiaries.

         5.       OPTIONAL REDEMPTION.

                  The Notes will not be redeemable at the Company's option prior
to February 1, 2003, except as provided below. Thereafter, the Notes will be
subject to redemption at the option of the Company, in whole or in part, upon
not less than 30 nor more than 60 days' notice to the Holders, at the redemption
prices (expressed as percentages of principal amount) set forth below plus
accrued and unpaid interest thereon to the applicable redemption date, if
redeemed during the twelve-month period beginning on February 1 of the years
indicated below:

         ----                                                        ----------
<S>                                                                  <C>

         2004...............................................         103.6667%
         2005...............................................         101.8333%
         2006 and thereafter................................         100.0000%
</TABLE>

                  Notwithstanding the foregoing, on and prior to February 1,
2001, the Company, at its option, may redeem, from time to time, up to 35% of
the aggregate principal amount of the Notes at a redemption price of 111% of the
principal amount thereof, plus accrued and unpaid interest thereon to the
redemption date with the net proceeds of a Public Equity Offering, as described
in Section 3.7 of the Indenture; provided that no less than 65% of the aggregate
principal amount of the Notes initially issued remains outstanding immediately
after giving effect to such redemption; and provided, further, that such notice
of redemption shall be given not later than 30 days, and such redemption shall
occur not later than 90 days, after the date of the closing of the transaction
giving rise to such Public Equity Offering. Unless the Company defaults in
making such redemption payment, on and after the redemption date, interest
ceases to accrue on the Notes or portions thereof called for redemption.

         6.       MANDATORY REDEMPTION.  Except as set forth in paragraph 7 
below, the Company shall not be required to make mandatory redemption payments
with respect to the Notes.

         7.       REPURCHASE AT OPTION OF HOLDER.

                  (a) Upon a Change of Control, the Company shall be required to
make an offer to Holders to repurchase all or any part (equal to $1,000 or an
integral multiple thereof) of each Holder's Notes at a purchase price equal to
101% of the aggregate principal amount thereof, plus accrued and unpaid interest
thereon to the date of purchase as provided in, and subject to the terms of, the
Indenture.

                  (b) If the Company or any Restricted Subsidiary consummates
any Asset Sale, the Company may be required, subject to the terms and conditions
of the Indenture, to utilize a certain portion of the proceeds received from
such Asset Sale to repurchase Notes at a purchase price equal to 100% of the
principal amount thereof, plus accrued and unpaid interest thereon to the date
of purchase.

         8. DENOMINATIONS, TRANSFER, EXCHANGE. The Notes are in registered form
without coupons in denominations of $1,000 and integral multiples of $1,000. The
transfer of Notes may be registered and Notes may be exchanged as provided in
the Indenture. The Registrar and the Trustee may require a Holder, among other
things, to furnish appropriate endorsements and transfer documents and the
Company may require a Holder to pay any taxes and fees required by law or
permitted by the Indenture. The Company need not exchange or register the
transfer of any Note or portion of a Note selected for redemption, except for
the unredeemed portion of any

                                       A-5

<PAGE>   90

Note being redeemed in part. Also, it need not exchange or register the transfer
of any Notes for a period of 15 days before a selection of Notes to be redeemed
or during the period between a Record Date and the corresponding Interest
Payment Date.

         9.       PERSONS DEEMED OWNERS.  The registered Holder of a Note may 
be treated as its owner for all purposes.

         10.      UNCLAIMED MONEY. If money for the payment of principal, 
premium, or interest remains unclaimed for one year, the Trustee and the Paying
Agent will pay the money back to the Company at its request. After that, all
liability of the Trustee and such Paying Agent with respect to such money shall
cease.

         11.      DEFEASANCE PRIOR TO REDEMPTION OR MATURITY. Subject to certain
conditions contained in the Indenture, the Company at any time may terminate
some or all of its obligations under the Notes and the Indenture if the Company
deposits with the Trustee money or Government Securities sufficient to pay the
principal of, premium, and interest on, the Notes to redemption or maturity, as
the case may be.

         12.      AMENDMENT, SUPPLEMENT AND WAIVER. Subject to certain 
exceptions, the Indenture or the Notes may be amended or supplemented with the
consent of the Holders of at least a majority in principal amount of the Notes
then outstanding, and any existing Default or Event or Default or compliance
with any provision of the Indenture or the Notes may be waived with the consent
of the Holders of a majority in principal amount of the then outstanding Notes.
Without the consent of any Holder of a Note, the Indenture or the Notes may be
amended or supplemented to cure any ambiguity, defect or inconsistency, to
provide for uncertificated Notes in addition to or in place of certificated
Notes, to provide for the assumption of the Company's obligations to Holders of
Notes in case of a merger or consolidation, to make any change that would
provide any additional rights or benefits to the Holders of the Notes or that
does not adversely affect the legal rights under the Indenture of any such
Holder, or to comply with the requirements of the SEC in order to effect or
maintain the qualification of the Indenture under the TIA as then in effect.

         13.      DEFAULTS AND REMEDIES.

                  Events of Default include: (i) default for 30 days in the
payment when due of any interest payable with respect to the Notes at any time
(provided that such 30-day grace period shall be inapplicable for the first two
scheduled interest payments due on the Notes); (ii) default in payment when due
(whether at maturity, upon redemption or repurchase, or otherwise) of the
principal of or premium, if any, on the Notes; (iii) failure by the Company or
any Restricted Subsidiary to comply with the provisions described under Articles
5, 10 or 11 or Sections 4.10 or 4.14 of the Indenture; (iv) failure by the
Company or any Restricted Subsidiary for 30 calendar days after notice from the
Trustee or Holders of at least 25% in aggregate principal amount of the Notes to
the Company and the Trustee to comply with any of its other agreements in the
Indenture, the Notes or the Pledge Agreement; (v) default under any mortgage,
indenture or instrument under which there may be issued or by which there may be
secured or evidenced


                                      A-6

any Indebtedness for money borrowed by the Company or any of its Restricted
Subsidiaries (or the payment of which is Guaranteed by the Company or any of its
Restricted Subsidiaries), whether such Indebtedness or Guarantee now exists or
is created after the date of the Indenture, which default (a) is caused by a
failure to pay principal of or premium, if any, or interest on such Indebtedness
following the expiration of the grace period provided in such Indebtedness on
the date of such default (a "Payment Default") or (b) results in the
acceleration of such Indebtedness (including any obligation to redeem or
repurchase such Indebtedness) prior to its express maturity and, in each case,
the principal amount of any such Indebtedness, together with the principal
amount of any other such Indebtedness under which there has been a Payment
Default or the maturity of which has been so accelerated, aggregates $1 million
or more; (vi) failure by the Company or any of its Restricted Subsidiaries to
pay final non-appealable judgments rendered against the Company or any of its
Restricted Subsidiaries aggregating in excess of $1 million, which judgments are
not paid, discharged or stayed for a period of 60 days after such judgments
become final and non-appealable; (vii) certain events of bankruptcy or
insolvency with respect to the Company or any Restricted Subsidiary; (viii)
certain events of breach, default, repudiation or unenforceability of the Pledge
Agreement; and (ix) any Guarantee of the Notes shall be held in a judicial
proceeding to be unenforceable or invalid or shall cease for any reason to be in
full force and effect, or any Restricted Subsidiary, or any Person acting on
behalf of any Restricted Subsidiary, shall deny or disaffirm its obligations
under its Guarantee of any Notes.

                  If an Event of Default occurs and is continuing, the Trustee
may pursue any available remedy by proceeding at law or in equity to collect any
payment due, or to enforce the performance of any provision, under the Notes or
the Indenture. The Trustee may refuse to enforce the Indenture or the Notes
unless it receives reasonable indemnity or security. Holders of Notes may not
enforce the Indenture or the Notes except as provided in the Indenture. Subject
to certain limitations, Holders of a majority in principal amount of the Notes
may direct the Trustee in its exercise of any trust or power. The Trustee may
withhold from Holders of the Notes notice of any continuing Default or Event of
Default (except under clauses (i) or (ii) above) if it determines that
withholding notice is in their interest.

         14. PLEDGE AGREEMENT. In order to secure the due and punctual payment
of the principal of, premium, and interest on the Notes and the payment and
performance of all other obligations of the Company to the Holders of the Notes
or the Trustee under the Indenture, the Company has granted a first priority
Lien on certain funds and Government Securities to the Trustee for the benefit
of the Holders, as more particularly described in the Pledge Agreement. If the
funds and Government Securities held in the Pledge Account exceed the amount
sufficient, in the opinion of a nationally recognized firm of independent public
accountants selected by the Company, to provide for payment in full of the first
two scheduled interest payments due on the Notes (or, in the event an interest
payment or interest payments have been made, an amount sufficient to provide for
payment in full of any interest payments remaining, up to and including the
second scheduled interest payment), if no Default or Event of Default is then
continuing, upon the satisfaction of certain conditions specified in the Pledge
Agreement, any such excess 

                                      A-7

<PAGE>   92
amount of funds and Government Securities shall be paid to the Company. Upon
such payment to the Company, the Lien of the Trustee thereon for the benefit of
the Holders shall be released.

         15. TRUSTEE'S DEALINGS WITH COMPANY. The Trustee, in its individual or
any other capacity, may make loans to, accept deposits from, and perform
services for the Company or its Affiliates, and may otherwise deal with the
Company or its Affiliates, as if it were not the Trustee, subject to the
provisions of TIA Section 310.

         16. NO RECOURSE AGAINST OTHERS. No past or present director, officer,
employee, incorporator, partner or stockholder of either of the Company or any
of its Subsidiaries, as such, shall have any liability for any obligations of
the Company or its Subsidiaries under any of the Notes, the Subsidiary
Guarantees or the Indenture or for any claim based on, in respect of or by
reason of such obligations or their creation. Each Holder by accepting a Note
waives and releases all such liability. This waiver and release are part of the
consideration for the issuance of the Notes.

         17. AUTHENTICATION.  This Note shall not be valid until authenticated 
by the manual signature of the Trustee or an authenticating agent.

         18. ABBREVIATIONS. Customary abbreviations may be used in the name of a
Holder or an assignee, such as: TEN COM (= tenants in common), TEN ENT (=
tenants by the entireties), JT TEN (= joint tenants with right of survivorship
and not as tenants in common), CUST (= Custodian), and U/G/M/A (= Uniform Gifts
to Minors Act).

         19. CUSIP NUMBERS. Pursuant to a recommendation promulgated by the
Committee on Uniform Security Identification Procedures, the Company has caused
CUSIP numbers to be printed on the Notes and the Trustee may use CUSIP numbers
in notices of redemption as a convenience to Holders. No representation is made
as to the accuracy of such numbers either as printed on the Notes or as
contained in any notice of redemption and reliance may be placed only on the
other identification numbers placed thereon.

         20. GOVERNING LAW.  THE INDENTURE AND THIS NOTE SHALL BE GOVERNED
BY, AND CONSTRUED AND ENFORCED IN ACCORDANCE WITH, THE INTERNAL
LAW OF THE STATE OF NEW YORK.

         21. SUCCESSOR CORPORATION. In the event a successor corporation assumes
all the obligations of the Company under the Notes and the Indenture, pursuant
to the terms thereof, the Company will be released from all such obligations.

         made, shall state that such investment is authorized to be made hereby
         and in particular satisfies the requirements of the preceding proviso
         and Section 2.4(e), shall contain the certification referred to in
         Section 2.4(b), if required, and shall be executed by an Officer of
         the Company.  All Government Securities shall be assigned to and held
         in the possession of, or, in the case of Government Securities
         maintained in book entry form with the Federal Reserve Bank,
         transferred to a book entry account in the name of, the Pledge Agent,
         for the benefit of the Trustee, with such guarantees as are customary,
         except that Government Securities maintained in book entry form with
         the Federal Reserve Bank shall be transferred to a book entry account
         in the name of the Pledge Agent at the Federal Reserve Bank that
         includes only Government Securities held by the Pledge Agent for its
         customers and segregated by separate recordation in the books and
         records of the Pledge Agent.  The Pledge Agent shall not be liable for
         losses on any investments made by it pursuant to and in compliance
         with such instructions.  In the absence of qualifying instructions
         from the Company that meet the requirements of this Section 2.4(a),
         the Pledge Agent shall have no obligation to invest funds held in the
         Pledge Account.

                 (b)      Security Interest in Investments.  No investment of
         funds in the Pledge Account shall be made unless the Company has
         certified to the Pledge Agent and the Trustee that, upon such
         investment, the Trustee will have a first priority perfected security
         interest in the applicable investment.  If a certificate as to a class
         of investments has been provided to the Pledge Agent, a certificate
         need not be issued with respect to individual investments in
         securities in that class if the certificate applicable to the class
         remains accurate with respect to such individual investments, which
         continued accuracy the Pledge Agent may conclusively assume.  On the
         Closing Date, and from time to time thereafter as required by Section
         11.2 of the Indenture and as required by the TIA, until the
         termination of this Agreement, the Trustee shall receive an Opinion of
         Counsel to the Company, dated each such date as applicable, which
         opinion shall meet the requirements of Section 314(b) of the TIA and
         shall comply with Section 11.2 of the Indenture.

                 (c)      Interest and Dividends.  All interest earned and
         dividends paid on funds invested in Government Securities shall be
         deposited in the Pledge Account as additional Collateral for the
         exclusive benefit of the Beneficiaries and, if not required to be
         disbursed in accordance with the terms hereof, shall be reinvested in
         accordance with the terms hereof at the Company's written instruction,
         and shall be available for disbursement to the Company upon
         satisfaction of the conditions set forth in Section 3.3.

                 (d)      Limitation on Pledge Agent's Responsibilities.  The
         Pledge Agent's sole responsibilities under this Section 2 shall be (A)
         to retain possession of certificated Government Securities (except,
         however, that the Pledge Agent may surrender possession to the issuer
         of any such Government Security for the purposes of effecting
         assignment, crediting interest, or reinvesting such security or
         reducing such security to cash) and to be the registered or designated
         owner of Government Securities which are not certificated, (B) to
         follow the Company's written instructions given in accordance with
         Section 2.4(a), (C) to invest and reinvest funds pursuant to this
         Section 2.4 and (D) to use reasonable efforts to reduce to cash such
         Government Securities as may be required to fund any disbursement or
         payment in accordance with Section 3.  In connection with clause (A)
         above, the Pledge Agent will maintain continuous possession in the
         State of New York of certificated Government Securities and cash
         included in the Collateral and will cause uncertificated Government
         Securities to be registered in the book-entry system of, and
         transferred to an account of the Pledge Agent or a sub-agent of the
         Pledge Agent at, the Federal Reserve Bank of New York or Dallas.
         Except as provided in Section 6, the Pledge Agent shall have no other
         responsibilities with respect to perfecting or maintaining the
         perfection of the Trustee's security interest in the Collateral and
         shall not be required to file any instrument, document or notice in
         any public office at any time or times.  In connection with clause (D)
         above and subject to the following sentence, the Pledge Agent shall
         not be required to reduce to cash any Government Securities to fund
         any disbursement or payment in accordance with Section 3 in the
         absence of written instructions signed by an Officer of the Company
         specifying the particular investment to liquidate.  If no such written
         instructions are received, the Pledge Agent may liquidate those
         Government Securities having the lowest interest rate per annum or if
         none such exist, those having the nearest maturity.

                 (e)      Manner of Investment.  Funds deposited in the Pledge
         Account shall initially be invested in accordance with the Initial
         Instructions (attached hereto as Exhibit B), which is in a manner such
         that there will be sufficient funds available without any further
         investment by the Company to cover all interest due on the outstanding
         Notes, as such interest becomes due, for each Interest Payment Date
         beginning on and including the Closing Date and through and including
         February 1, 1999, provided that such investments shall have such
         maturities and/or interest payment dates such that funds will be
         available with respect to each such Interest Payment Date no later
         than the time the Pledge Agent is required to disburse such funds to
         the Trustee pursuant to Section 3.1.  The Pledge Agent shall have no
         responsibility for determining whether funds held in the Pledge
         Account shall have been invested in such a manner so as to comply with
         the requirements of this subsection (e)

                 2.5      Substitution of Pledge Agent.  The Pledge Agent may
resign by giving no less than 20 Business Days prior written notice to the
Company and the Trustee.  Such resignation shall take effect upon the later to
occur of (i) delivery of all funds and Government Securities maintained by the
Pledge Agent hereunder and copies of all books, records, plans and other
documents in the Pledge Agent's possession relating to such funds or Government





                                       4
<PAGE>   5
Securities or this Agreement to a successor Pledge Agent mutually approved by
the Company and the Trustee (which approvals shall not be unreasonably withheld
or delayed) and (ii) the Company, the Trustee and such successor agent enter
into this Agreement or any written successor agreement no less favorable to the
interests of the holders of the Notes and the Trustee than this Agreement.  The
Pledge Agent shall thereafter be discharged of all obligations under this
Agreement and shall have no further duties, obligations or responsibilities in
connection herewith, except as set forth in Section 4.  If a successor pledge
agent has not been appointed or has not accepted such appointment within 20
Business Days after notice of resignation is given to the Company, the Pledge
Agent may apply to a court of competent jurisdiction for the appointment of a
successor pledge agent.

                 2.6      Pledge Account Statement.  At least 30 days prior to
each Interest Payment Date, the Pledge Agent shall deliver to the Company and
the Trustee a statement setting forth with reasonable particularity the balance
of funds then in the Pledge Account and the manner in which such funds are
invested.  The parties hereto irrevocably instruct the Pledge Agent that on the
first date upon which the balance in the Pledge Account (including the holdings
of all Government Securities) is reduced to zero, the Pledge Agent shall
deliver to the Company and to the Trustee a notice that the balance in the
Pledge Account has been reduced to zero.

                 3.       DISBURSEMENTS.

                 3.1      Payment Notice and Disbursement Request;
Disbursements.  The Trustee shall, at least five Business Days prior to an
Interest Payment Date, submit to the Pledge Agent a completed Payment Notice
and Disbursement Request substantially in the form of Exhibit A hereto.

                 The Pledge Agent's disbursement pursuant to any Payment Notice
and Disbursement Request shall be subject to the satisfaction of the applicable
conditions set forth in Section 3.2.  If such Payment Notice and Disbursement
Request is not rejected by the Pledge Agent, the Pledge Agent, as soon as
reasonably practicable on the Interest Payment Date, but in no event later than
12:00 Noon (New York City time) on the Interest Payment Date, shall disburse
the funds requested in such Payment Notice and Disbursement Request by wire or
book-entry transfer of immediately available funds to the account of the
Trustee for the benefit of the Beneficiaries.  The Pledge Agent shall notify
the Trustee as soon as reasonably possible (but not later than two Business
Days from the date of receipt of the Payment Notice and Disbursement Request)
if any Payment Notice and Disbursement Request is rejected and the reason(s)
therefor.  In the event such rejection is based upon nonsatisfaction of the
condition in Section 3.2(a) below, the Trustee shall thereupon resubmit the
Payment Notice and Disbursement Request with appropriate changes.

                 3.2      Conditions Precedent to Disbursement.  The Pledge
Agent's payment of any disbursement shall be made only if:  (a) the Trustee
shall have submitted, in accordance with the provisions of Section 3.1 herein,
a completed Payment Notice and Disbursement Request to the Pledge Agent
substantially in the form of Exhibit A with blanks appropriately filled in, (b)





                                       5
<PAGE>   6
the Company shall have complied with the requirements of Section 11.3 of the
Indenture, and (c) the Pledge Agent shall not have received any notice from the
Trustee that as a result of an Event of Default the indebtedness represented by
the Notes has been accelerated and has become due and payable (in which event
the Pledge Agent shall apply all Available Funds as required by Section 6(b)
(iii)).

                 3.3      Disbursements to Company.  If (i) a portion of the
Notes has been retired by the Company and submitted to the Trustee for
cancellation or the Company has deposited with the Trustee from funds otherwise
available to the Company cash sufficient to pay interest scheduled to be paid
on an Interest Payment Date, and as a result of such retirement or deposit, or
(ii) as a result of overfunding of the Pledge Account, interest or dividends
earned on Collateral, or realization of proceeds thereof in accordance with the
terms hereof, the funds or Pledged Securities held in the Pledge Account exceed
the amount sufficient, in the opinion of a nationally recognized firm of
independent public accountants selected by the Company, to provide for payment
in full of the first two scheduled interest payments due on the Notes (or, in
the event an interest payment or interest payments have been made, an amount
sufficient to provide for payment in full of any interest payments remaining,
up to and including the second scheduled interest payment), if no Default or
Event of Default is then continuing, upon the written request of the Company to
the Pledge Agent and the Trustee, any such excess amount of Collateral shall be
paid to the Company upon compliance with the release of collateral provisions
of the TIA and upon receipt by the Pledge Agent of a notice relating thereto
from the Trustee.

                 4.       PLEDGE AGENT.

                 The Pledge Agent's responsibility and liability under this
Agreement shall be limited as follows:  (i) the Pledge Agent does not
represent, warrant or guaranty to the holders of the Notes from time to time
the performance of the Company; (ii) the Pledge Agent shall have no
responsibility to the Company or the holders of the Notes or the Trustee from
time to time as a consequence of performance or non-performance by the Pledge
Agent hereunder, except for any gross negligence or willful misconduct of the
Pledge Agent; (iii) the Company shall remain solely responsible for all aspects
of the Company's business and conduct; and (iv) the Pledge Agent is not
obligated to supervise, inspect or inform the Company or any third party of any
matter referred to above.

                 No implied covenants or obligations shall be inferred from
this Agreement against the Pledge Agent, nor shall the Pledge Agent be bound by
the provisions of any agreement beyond the specific terms hereof.  Specifically
and without limiting the foregoing, the Pledge Agent shall in no event have any
liability in connection with its investment, reinvestment or liquidation, in
good faith and in accordance with the terms hereof, of any funds or Government
Securities held by it hereunder, including without limitation any liability for
any delay not resulting from gross negligence or willful misconduct in such
investment, reinvestment or liquidation, or for any loss of principal or income
incident to any such delay.





                                       6
<PAGE>   7
                 The Pledge Agent shall be entitled to rely upon any judicial
order or judgment, upon any written opinion of counsel or upon any
certification, instruction, notice, or other writing delivered to it by the
Company or the Trustee in compliance with the provisions of this Agreement
without being required to determine the authenticity or the correctness of any
fact stated therein or the propriety or validity of service thereof.  The
Pledge Agent may act in reliance upon any instrument comporting with the
provisions of this Agreement or signature believed by it to be genuine and may
assume that any person purporting to give notice or receipt or advice or make
any statement or execute any document in connection with the provisions hereof
has been duly authorized to do so.

                 At any time the Pledge Agent may request in writing an
instruction in writing from the Company, and may at its own option include in
such request the course of action it proposes to take and the date on which it
proposes to act, regarding any matter arising in connection with its duties and
obligations hereunder; provided, however, that the Pledge Agent shall state in
such request that it believes in good faith that such proposed course of action
is consistent with another identified provision of this Agreement.  The Pledge
Agent shall not be liable to the Company for acting without the Company's
consent in accordance with such a proposal on or after the date specified
therein if (i) the specified date is at least two (2) Business Days after the
Company receives the Pledge Agent's request for instructions and its proposed
course of action, and (ii) prior to so acting, the Pledge Agent has not
received the written instructions requested from the Company.

                 The Pledge Agent may act pursuant to the written advice of
counsel chosen by it with respect to any matter relating to this Agreement and
(subject to clause (ii) of the first paragraph of this Section 4) shall not be
liable for any action taken or omitted in accordance with such advice.

                 The Pledge Agent shall not be called upon to advise any party
as to selling or retaining, or taking or refraining from taking any action with
respect to, any securities or other property deposited hereunder.

                 In the event of any ambiguity in the provisions of this
Agreement with respect to any funds or property deposited hereunder, the Pledge
Agent shall be entitled to refuse to comply with any and all claims, demands or
instructions with respect to such funds or property, and the Pledge Agent shall
not be or become liable for its failure or refusal to comply with conflicting
claims, demands or instructions.  The Pledge Agent shall be entitled to refuse
to act until either any conflicting or adverse claims or demands shall have
been finally determined by a court of competent jurisdiction or settled by
agreement between the conflicting claimants as evidenced in a writing,
satisfactory to the Pledge Agent, or the Pledge Agent shall have received
security or an indemnity satisfactory to the Pledge Agent sufficient to save
the Pledge Agent harmless from and against any and all loss, liability or
expense which the Pledge Agent may incur by reason of its acting.  The Pledge
Agent may in addition elect in its sole option to commence an interpleader
action or seek other judicial relief or orders as the Pledge Agent may deem
necessary.





                                       7
<PAGE>   8
                 No provision of this Agreement shall require the Pledge Agent
to expend or risk its own funds or otherwise incur any financial liability in
the performance of any of its duties hereunder.

                 5.       INDEMNITY.  The Company shall indemnify, hold
harmless and defend the Pledge Agent and its directors, officers, agents,
employees and controlling persons, from and against any and all claims,
actions, obligations, liabilities and expenses, including defense costs,
investigative fees and costs, legal fees, and claims for damages, arising from
the Pledge Agent's performance or non-performance, or in connection with its
acceptance or appointment as Pledge Agent, under this Agreement, except to the
extent that such liability, expense or claim is solely and directly
attributable to the negligence or willful misconduct of any of the foregoing
persons.  The provisions of this Section 5 shall survive any termination,
satisfaction or discharge of this Agreement as well as the resignation or
removal of the Pledge Agent.

                 6.       GRANT OF SECURITY INTERESTS; INSTRUCTIONS TO PLEDGE 
AGENT.

                 (a)      The Company hereby irrevocably grants a first
         priority security interest in and lien on, and pledges, assigns, and
         sets over to the Trustee for the benefit of the Beneficiaries, all of
         the Company's right, title and interest in the Pledge Account, and all
         property now or hereafter placed or deposited in, or delivered to the
         Pledge Agent for placement or deposit in, the Pledge Account,
         including, without limitation, all funds held therein, all Government
         Securities held by (or otherwise maintained in the name of) the Pledge
         Agent pursuant to Section 2, and all proceeds thereof as well as all
         rights of the Company under this Agreement (collectively, the
         "Collateral"), in order to secure the due and punctual payment of the
         principal of, premium, and interest on the Notes when and as the same
         shall be due and payable on each Interest Payment Date, at maturity or
         by acceleration, and interest on the overdue principal of and interest
         (to the extent permitted by law), if any, on the Notes and the payment
         and performance of all other obligations of the Company to the Holders
         of the Notes or the Trustee under the Indenture and this Agreement
         with respect to the Notes, according to the terms hereunder or
         thereunder.  The Pledge Agent hereby acknowledges the Trustee's
         security interest and lien as set forth above.  The Company shall take
         all actions necessary on its part to insure the continuance of a first
         priority security interest in the Collateral in favor of the Trustee
         in order to secure all such obligations and indebtedness.

                 (b)      The Company and the Trustee hereby irrevocably
         instruct the Pledge Agent to, and the Pledge Agent shall:  (i) (A)
         maintain sole dominion and control over funds and Government
         Securities in the Pledge Account for the benefit of the Trustee to the
         extent specifically required herein, (B) maintain, or cause its agent
         within the State of New York to maintain, possession of all
         certificated Government Securities purchased hereunder that are
         physically possessed by the Pledge Agent in order for the Trustee to
         enjoy a continuous perfected first priority security interest therein
         under the law of the State of New York (the Company hereby agreeing
         that in the event any certificated





                                       8
<PAGE>   9
         Government Securities are in the possession of the Company or a third
         party, the Company shall use its best efforts to deliver all such
         certificates to the Pledge Agent), (C) take all steps specified by the
         Company pursuant to Section 6 to cause the Trustee to enjoy a
         continuous perfected first priority security interest under any
         applicable Federal and State of New York law in all Government
         Securities purchased hereunder that are not certificated and (D)
         maintain the Collateral free and clear of all Liens, security
         interests, safekeeping or other charges, demands and claims against
         the Pledge Agent of any nature now or hereafter existing in favor of
         anyone other than the Trustee; (ii) promptly notify the Trustee if the
         Pledge Agent receives written notice that any Person other than the
         Trustee has a Lien or security interest upon any portion of the
         Collateral; and (iii) in addition to disbursing amounts pledged
         pursuant to any Payment Notice and Disbursement Requests given to it
         by the Trustee pursuant to Section 3, upon receipt of written notice
         from the Trustee of the acceleration of the maturity of the Notes, and
         direction from the Trustee to disburse all Available Funds to the
         Trustee, as promptly as practicable, after following, if it so
         chooses, the procedures set forth in the fourth paragraph of Section
         4, disburse all funds held in the Pledge Account to the Trustee and
         transfer title to all Government Securities held by the Pledge Agent
         hereunder to the Trustee.  The Lien and security interest provided for
         by this Section 6 shall automatically terminate and cease as to, and
         shall not extend or apply to, and the Trustee shall have no security
         interest in or Lien on, any funds disbursed by the Pledge Agent to the
         Company pursuant to this Agreement to the extent not inconsistent with
         the terms hereof.  Notwithstanding any other provision contained in
         this Agreement, the Pledge Agent shall act solely as the Trustee's
         agent in connection with its duties under this Agreement.  The Pledge
         Agent shall not have any right to receive compensation from the
         Trustee and shall have no authority to obligate the Trustee or to
         compromise or pledge its security interest hereunder.  Accordingly,
         the Pledge Agent is hereby directed to cooperate with the Trustee in
         the exercise of its rights in the Collateral provided for herein.

                 (c)      Any money and Government Securities collected by the
         Trustee pursuant to Section 6(b) (iii) shall be applied as provided in
         Section 6.10 of the Indenture.

                 (d)      Upon demand, the Company will execute and deliver to
         the Trustee such instruments and documents as the Trustee may deem
         necessary or advisable to confirm or perfect the rights of the Trustee
         under this Agreement and the Trustee's interest in the Collateral.
         The Trustee shall be entitled to take all necessary action to preserve
         and protect the security interest created hereby as a lien and
         encumbrance upon the Collateral.

                 (e)      The Company hereby appoints the Trustee as its
         attorney-in-fact with full power of substitution to do any act which
         the Company is obligated hereto to do, and the Trustee may exercise
         such rights as the Company might exercise with respect to the
         Collateral and take any action in the Company's name to protect the
         Trustee's security interest hereunder.  In addition to the rights
         provided under Section 6(b)(iii) hereof, upon





                                       9
<PAGE>   10
         an Event of Default and for so long as such Event of Default
         continues, the Trustee may exercise in respect of the Collateral, in
         addition to other rights and remedies provided for herein or otherwise
         available to it, all the rights and remedies of a secured party under
         the Uniform Commercial Code or other applicable law, and the Trustee
         may also upon obtaining possession of the Collateral as set forth
         herein, without notice to the Company except as specified below, sell
         the Collateral or any part thereof in one or more parcels at public or
         private sale, at any exchange, broker's board or at any of the
         Trustee's offices or elsewhere, for cash, on credit or for future
         delivery, and upon such other terms as the Trustee may deem
         commercially reasonable.  The Company acknowledges and agrees that any
         such private sale may result in prices and other terms less favorable
         to the seller than if such sale were a public sale.  The Company
         agrees that, to the extent notice of sale shall be required by law, at
         least 10 days notice to the Company of the time and place of any
         public sale or the time after which any private sale is to be made
         shall constitute reasonable notification.  The Trustee shall not be
         obligated to make any sale regardless of notice of sale having been
         given.  The Trustee may adjourn any public or private sale from time
         to time by announcement at the time and place fixed therefor, and such
         sale may, without further notice, be made at the time and place to
         which it was so adjourned.

                 7.       TERMINATION.  Upon the earliest to occur of (i) the
         date upon which the balance of Available Funds shall have been reduced
         to zero, (ii) if no Default or Event of Default exists, the date upon
         which the Company shall have paid in full in accordance with the terms
         of the Indenture the first two scheduled interest payments due on the
         Notes, (iii) the payment in full of all obligations of the Company

Agreement unless otherwise defined herein.

         This letter constitutes a Payment Notice and Disbursement Request
under the Pledge Agreement.

         [CHOOSE ONE OF THE FOLLOWING, AS APPLICABLE:]

         [The undersigned hereby notifies you that a scheduled interest payment
in the amount of $___________ is due and payable on _____________, ____ and the
Company has not deposited with the Trustee from funds otherwise available to

Borrower to the Agent by means of a Letter of Credit Request Form describing
the transaction proposed to be supported thereby and specifying (a) the
requested date of issuance (which shall be a Business Day), (b) the face amount
of the Letter of Credit, (c) the expiration date of the Letter of Credit, (d)
the name and address of the beneficiary, and (e) the form of the draft and any

at the time of any drawing (such notice to set forth the exact wording of such
documents or to attach copies thereof).

         Section 2.7 Payments Constitute Advances. Each payment by the Issuing
Bank pursuant to a drawing under a Letter of Credit shall constitute and be
deemed an Advance to the Borrower and this Agreement as of the day and time
such payment is made by the Issuing Bank and in the amount of such payment.

         Section 2.8 Letter of Credit Fee. The Borrower shall pay to Agent for
the account of the Banks a letter of credit fee payable on the date each Letter
of Credit is issued in an amount equal to the greater of (a) one percent per
annum of the face amount of such Letter of Credit, for the period during which
such Letter of Credit will remain outstanding, based on a 360 day year and the
actual number of days elapsed or (b) $300.

         Section 2.9 Pro Rata Participations in Letters of Credit. By the
issuance of a Letter of Credit hereunder by a Bank and without further action
on the part of the Agent or the Banks, each Bank hereby agrees to purchase and
such Bank agrees to sell, an undivided participation (which participation shall
be nonrecourse to such Bank) in such Letter of Credit and each payment made
under such Letter of Credit equal to such Bank's pro rata (based on its
Commitment) share of such Letter of Credit and each payment made under such
Letter of Credit, effective upon the issuance of the Letter of Credit. Each
Bank hereby absolutely and unconditionally assumes, as primary obligor and not
as a surety, and agrees to pay and discharge, and to indemnify and hold the
issuing Bank harmless from liability in respect of such Bank's pro rata share
of any payment made under such Letter of Credit.

         Section 2.10 Obligations Absolute. The obligations of the Borrower
under this Agreement and the other Loan Documents (including without limitation
the obligation of the Borrower to reimburse the Issuing Bank for draws under
any Letter of Credit) shall be absolute, unconditional, and irrevocable, and
shall be performed strictly in accordance with the terms of this Agreement and
the other Loan Documents under all circumstances whatsoever, including without
limitation the following circumstances:

                  (a)      Any lack of validity or enforceability of any Letter
         of Credit or any other Loan Document;

                  (b)      Any amendment or waiver of or any consent to
         departure from any Loan Document;

                  (c) The existence of any claim, set-off, counterclaim,
         defense or other rights which the Borrower, any Obligated Party, or
         any other Person may have at any time against any beneficiary of any
         Letter of Credit, the Agent, any Bank, or any other Person, whether in
         connection with this Agreement or any other Loan Document or any
         unrelated transaction;

                  (d) Any statement, draft, or other document presented under
         any Letter of Credit appearing regular on its face but proving to be
         forged, fraudulent, invalid, or

                                     - 13 -

<PAGE>   19



         insufficient in any respect or any statement therein being untrue or
         inaccurate in any respect whatsoever; or

                  (e) Payment by the Issuing Bank under any Letter of Credit
         against presentation of a draft or other document which does not
         strictly comply with the terms of such Letter of Credit.

         Section 2.11 Limitation of Liability. The Borrower assumes all risks
of the acts or omissions of any beneficiary of any Letter of Credit with
respect to its use of such Letter of Credit. Neither the Agent nor any Bank nor
any of its respective officers or directors shall have any responsibility or
liability to the Borrower or any other Person for: (a) the failure of any draft
to bear any reference or adequate reference to any Letter of Credit, or the
failure of any documents to accompany any draft at negotiation, or the failure
of any Person to surrender or to take up any Letter of Credit or to send
documents apart from drafts as required by the terms of any Letter of Credit,
or the failure of any Person to note the amount of any instrument on any Letter
of Credit, each of which requirements, if contained in any Letter of Credit
itself, it is agreed may be waived by the Agent and the Banks, (b) errors,
omissions, interruptions, or delays in transmission or delivery of any
messages, (c) the validity, sufficiency, or genuineness of any draft or other
document, or any endorsement(s) thereon, even if any such draft, document or
endorsement should in fact prove to be in any and all respects invalid,
insufficient, fraudulent, or forged or any statement therein is untrue or
inaccurate in any respect, or (d) the payment by a Bank to the beneficiary of
any Letter of Credit against presentation of any draft or other document that
does not strictly comply with the terms of the Letter of Credit. The Borrower
shall have a claim against the Agent or any Bank, and the Agent and the Banks
shall be liable to the Borrower, to the extent, and solely to the extent, of
any direct, but not consequential, damages suffered by the Borrower which the
Borrower proves in a final nonappealable judgment were caused by (i) the
Agent's, the Issuing Bank's or a Bank's willful misconduct or gross negligence
in determining whether documents presented under any Letter of Credit complied
with the terms thereof or (ii) the Issuing Bank's willful failure to pay under
any Letter of Credit after presentation to it of documents strictly complying
with the terms and conditions of such Letter of Credit. The Issuing Bank may
accept documents that appear on their face to be in order, without
responsibility for further investigation, regardless of any notice or
information to the contrary.


                                  ARTICLE III

                Requests for Advances; Interest; Payments; Fees

         Section 3.1 Borrowing Procedure. The Borrower shall give the Agent
notice by means of an Advance Request Form of each requested Advance at least
one Business Day before the requested date of each Advance, specifying: (a) the
requested date of such Advance (which shall be a Business Day), and (b) the
amount of such Advance. The Agent at its option may accept telephonic requests
for Advances, provided that such acceptance shall not constitute a waiver of
the Agent's right to delivery of an Advance Request Form in connection with
subsequent Advances. Any telephonic request for an Advance by the Borrower
shall be promptly confirmed

                                     - 14 -

<PAGE>   20



by submission of the properly completed appropriate advance request form to the
Agent. Each Advance shall be in a minimum principal amount of $50,000 or an
integral multiple thereof. The Agent shall notify each Bank of the contents of
each such notice. Not later than 1:00 P.M. Houston, Texas time on the date
specified for each Advance hereunder, each Bank will make available to the
Agent at the Principal Office in immediately available funds, for the account
of the Borrower, the amount requested by the Agent from it, which shall not
exceed its pro rata share of the Total Commitment. After the Agent's receipt of
such funds and subject to the other terms and conditions of this Agreement, the
Agent will make each Advance available to the Borrower by depositing the same,
in immediately available funds, in an account of the Borrower (designated by
the Borrower) maintained with the Agent at the Principal Office. All notices
under this Section shall be irrevocable and shall be given not later than 11:00
A.M. Houston, Texas, time on the day which is not less than the number of
Business Days specified above for such notice.

         Section 3.2 Interest. The unpaid principal amount of the Advances
shall bear interest at a varying rate per annum equal from day to day to the
lesser of (a) the Maximum Rate, or (b) the Applicable Rate. If at any time the
Applicable Rate for any Advance shall exceed the Maximum Rate, thereby causing
the interest accruing on such Advance to be limited to the Maximum Rate, then
any subsequent reduction in the Applicable Rate for such Advance shall not
reduce the rate of interest on such Advance below the Maximum Rate until the
aggregate amount of interest accrued on such Advance equals the aggregate
amount of interest which would have accrued on such Advance if the Applicable
Rate had at all times been in effect. Accrued and unpaid interest on the
Advances shall be due and payable as follows:

                  (i)      on the first day of each calendar month, beginning 
June 1, 1998; and

                  (ii)     on the Termination Date.

Notwithstanding the foregoing, any outstanding principal of any Advance and (to
the fullest extent permitted by law) any other amount payable by the Borrower
under this Agreement or any other Loan Document that is not paid in full when
due (whether at stated maturity, by acceleration, or otherwise) shall bear
interest at the Default Rate for the period from and including the due date
thereof to but excluding the date the same is paid in full. Interest payable at
the Default Rate shall be payable from time to time on demand.

         Section 3.3 Unused Availability Commitment Fee. The Borrower agrees to
pay to the Agent for the account of each Bank (pro rata in accordance with the
Commitment of each Bank) an unused availability commitment fee on the daily
average unused amount of the Total Commitment for the period from and including
the date of this Agreement to and including the Termination Date, at the rate
of one-quarter of one percent per annum, based on a 360 day year and the actual
number of days elapsed. For purposes of calculating the commitment fee
hereunder, the Credit Commitment shall be deemed utilized by the amount of all
Advances plus the outstanding Letter of Credit Liabilities. The accrued unused
availability commitment fee shall be payable in arrears on the first day of
each calendar quarter beginning July 1, 1998, and on the Termination Date.


                                     - 15 -

<PAGE>   21



         Section 3.4 Reduction or Termination of Commitments. The Borrower
shall have the right to terminate in whole or reduce in part the unused portion
of the Total Commitment upon at least three Business Days' prior notice (which
notice shall be irrevocable) to the Agent specifying the effective date
thereof, whether a termination or reduction is being made, and the amount of
any partial reduction, provided that each partial reduction shall be in the
amount of $1,000,000 or an integral multiple thereof and the Borrower shall
simultaneously prepay the amount by which the unpaid principal amount of the
respective Advances exceeds the Total Commitment (after giving effect to such
notice) plus accrued and unpaid interest on the principal amount so prepaid.
The Commitment may not be reinstated after it has been terminated or reduced.

         Section 3.5 Facility Fee.  On the date hereof, the Borrower shall
pay to Agent for the benefit of the Banks a facility fee of $50,000.

         Section 3.6 Administrative Fee.  The Borrower shall pay to Agent, 
solely for its own account, an annual administrative fee as separately agreed
between the Borrower and the Agent.


                                   ARTICLE IV

     Payments and Allocations of Advances; Yield Protection and Illegality

         Section 4.1 Method of Payment. All payments of principal, interest,
and other amounts to be made by the Borrower under this Agreement and the other
Loan Documents shall be made to the Agent at the Principal Office for the
account of each Bank's Applicable Lending Office in Dollars and in immediately
available funds, without setoff, deduction, or counterclaim, not later than
11:00 A.M., Houston, Texas time on the date on which such payment shall become
due (each such payment made after such time on such due date to be deemed to
have been made on the next succeeding Business Day). The Borrower shall, at the
time of making each such payment, specify to the Agent the sums payable by the
Borrower under this Agreement and the other Loan Documents to which such
payment is to be applied (and in the event that the Borrower fails to so
specify, or if an Event of Default has occurred and is continuing, the Agent
may apply such payment to the Obligations in such order and manner as it may
elect in its sole discretion, subject to Sections 4.3 and 4.4 hereof). Each
payment received by the Agent under this Agreement or any other Loan Document
for the account of a Bank shall be paid promptly to such Bank, in immediately
available funds, for the account of such Bank. Whenever any payment under this
Agreement or any other Loan Document shall be stated to be due on a day that is
not a Business Day, such payment may be made on the next succeeding Business
Day, and such extension of time shall in such case be included in the
computation of the payment of interest and commitment fee, as the case may be.

         Section 4.2 Voluntary Prepayment. The Borrower may, upon at least one
Business Day prior notice to the Agent, prepay the Advances in whole at any
time or from time to time in part without premium or penalty but with accrued
interest to the date of prepayment on the amount so prepaid, provided that each
partial prepayment shall be in a minimum principal amount of

                                     - 16 -

<PAGE>   22



$50,000 or an integral multiple thereof. All notices under this Section shall
be irrevocable and shall be given not later than 11:00 A.M. Houston, Texas,
time on the day specified above.

         Section 4.3 Mandatory Prepayments. If at any time the aggregate
outstanding principal amount of the Advances plus the Total Letter of Credit
Liabilities exceeds the Borrowing Base, the Borrower shall promptly prepay the
outstanding Advances by the amount of the excess plus accrued and unpaid
interest on the amount so prepaid. If no Advances are outstanding, the Borrower
shall immediately pledge to the Lender cash or cash equivalent investments in
an amount equal to the excess as security for the Obligations.

         Section 4.4 Pro Rata Treatment.  Except to the extent otherwise
provided herein: (a) each Advance shall be by the Banks, each payment of
commitment fee under Section 3.3 shall be made for the account of the Banks,
and each termination or reduction of the Total Commitment under Section 3.4
shall be applied to the respective Commitments of the Banks, pro rata according
to the respective unused Total Commitment; (b) the making, of Advances shall be
made pro rata among the Banks according to the amounts of their respective
Commitment; and (c) each payment and prepayment of principal of or interest on
Advances by the Borrower shall be made to the Agent for the account of the
Banks holding Advances pro rata in accordance with the respective unpaid
principal amounts of such Advances held by such Banks.

         Section 4.5 Non-Receipt of Funds by the Agent. Unless the Agent shall
have been notified by a Bank or the Borrower (the "Payor") prior to the date on
which such Bank is to make payment to the Agent of the proceeds of an Advance
to be made by it hereunder or the Borrower is to make a payment to the Agent
for the account of one or more of the Banks, as the case may be (such payment
being herein called the "Required Payment"), which notice shall be effective
upon receipt, that the Payor does not intend to make the Required Payment to
the Agent, the Agent may assume that the Required Payment has been made and
may, in reliance upon such assumption (but shall not be required to), make the
amount thereof available to the intended recipient on such date and, if the
Payor has not in fact made the Required Payment to the Agent, the recipient of
such payment shall, on demand, pay to the Agent the amount made available to it
together with interest thereon in respect of the period commencing on the date
such amount was so made available by the Agent until the date the Agent
recovers such amount at a rate per annum equal to the Federal Funds Rate for
such period.

         Section 4.6 Withholding Taxes. All payments by the Borrower of
principal of and interest on the Advances and of all fees and other amounts
payable under any Loan Document are payable without deduction for or on account
of any present or future taxes, duties or other charges levied or imposed by
the United States of America or by the government of any jurisdiction outside
the United States of America or by any political subdivision or taxing
authority of or in any of the foregoing through withholding or deduction with
respect to any such payments. If any such taxes, duties or other charges are so
levied or imposed, the Borrower will pay additional interest or will make
additional payments in such amounts so that every net payment of principal of
and interest on the Advances and of all other amounts payable by it under any
Loan Document, after withholding or deduction for or on account of any such
present or future taxes, duties or other charges, will not be less than the
amount provided for herein or therein, provided that the Borrower shall have no
obligation to pay such additional amounts to

                                     - 17 -

<PAGE>   23



any Bank to the extent that such taxes, duties, or other charges are levied or
imposed by reason of the failure of such Bank to comply with the provisions of
Section 4.7. The Borrower shall furnish promptly to the Agent for distribution
to each affected Bank, as the case may be, official receipts evidencing any
such withholding or reduction.

         Section 4.7 Withholding Tax Exemption. Each Bank that is not
incorporated under the laws of the United States of America or a state thereof
agrees that it will deliver to the Borrower and the Agent two duly completed
copies of United States Internal Revenue Service Form 1001 or 4224, certifying
in either case that such Bank is entitled to receive payments from the Borrower
under any Loan Document without deduction or withholding of any United States
federal income taxes. Each Bank that so delivers a Form 1001 or 4224 further
undertakes to deliver to Borrower and the Agent two additional copies of such
form (or a successor form) on or before the date such form expires or becomes
obsolete or after the occurrence of any event requiring a change in the most
recent form so delivered by it, and such amendments thereto or extensions or
renewals thereof as may be reasonably requested by the Borrower or the Agent,
in each case certifying that such Bank is entitled to receive payments from the
Borrower under any Loan Document without deduction or withholding of any United
States federal income taxes, unless an event (including without limitation any
change in treaty, law or regulation) has occurred prior to the date on which
any such delivery would otherwise be required which renders all such forms
inapplicable or which would prevent such Bank from duly completing and
delivering any such form with respect to it and such Bank advises the Borrower
and the Agent that it is not capable of receiving such payments without any
deduction or withholding of United States federal income tax.

         Section 4.8 Computation of Interest. Interest on the Advances and all
other amounts payable by the Borrower hereunder shall be computed on the basis
of a year of 360 days and the actual number of days elapsed (including the
first day but excluding the last day) unless such calculation would result in a
usurious rate, in which case interest shall be calculated on the basis of a
year of 365 or 366 days, as the case may be.

         Section 4.9 Additional Costs in Respect of Letters of Credit. If as a
result of any Regulatory Change there shall be imposed, modified, or deemed
applicable any tax, reserve, special deposit, or similar requirement against or
with respect to or measured by reference to Letters of Credit issued or to be
issued hereunder or the Issuing Bank's commitment to issue Letters of Credit
hereunder, and the result shall be to increase the cost to the Issuing Bank of
issuing or maintaining any Letter of Credit or its commitment to issue Letters
of Credit hereunder or reduce any amount receivable by the Issuing Bank
hereunder in respect of any Letter of Credit (which increase in cost, or
reduction in amount receivable, shall be the result of the Issuing Bank's
reasonable allocation of the aggregate of such increases or reductions
resulting from such event), then, upon demand by the Issuing Bank, the Borrower
agrees to pay the Issuing Bank such additional amounts as shall be sufficient
to compensate the Issuing Bank for such increased costs or reductions in
amount. A statement as to such increased costs or reductions in amount incurred
by the Issuing Bank, submitted by the Issuing Bank to the Borrower, shall be
conclusive as to the amount thereof, provided that the determination thereof is
made on a reasonable basis.

         Section 4.10 Capital Adequacy. If after the date hereof, any Bank
shall have determined that the adoption or implementation of any applicable
law, rule, or regulation regarding capital adequacy, or any change therein, or
any change in the interpretation or administration thereof by any central bank
or other Governmental Authority charged with the interpretation or
administration thereof, or compliance by such Bank (or its parent) with any
guideline, request, or directive regarding capital adequacy (whether or not
having the force of law) of any central bank or other Governmental Authority,
has or would have the effect of reducing the rate of return on such Bank's (or
its parent's) capital as a consequence of its obligations hereunder or the
transactions contemplated hereby to a level below that which such Bank (or its
parent) could have achieved but for such adoption, implementation, change or
compliance (taking into consideration such Bank's policies with respect to
capital adequacy) by an amount deemed by such Bank to be material, then from
time to time, within 60 days after demand by such Bank (with a copy to the
Agent), the Borrower shall pay to such Bank such additional amount or amounts
as will compensate such Bank (or its parent) for such reduction. A certificate
of such Bank claiming compensation under this Section and setting forth the
additional amount or amounts to be paid to it hereunder shall be conclusive,
provided that the determination thereof is made on a reasonable basis. In
determining such amount or amounts, such Bank may use any reasonable averaging
and attribution methods.

                                   ARTICLE V

                                    Security

         Section 5.1 Collateral. To secure full and complete payment and
performance of the Obligations, the Borrower shall execute and deliver or cause
to be executed and delivered the documents described below covering the
property and collateral described in this Section 5.1 (which, together with any
other property and collateral which may now or hereafter secure the Obligations
or any part thereof, is sometimes herein called the "Collateral"):

                  (a) The Borrower shall grant to the Agent for the benefit of
         the Banks a first priority, and perfected, security interest in all of
         its accounts, accounts receivable, money, chattel paper, documents,
         and instruments, whether now owned or hereafter acquired, and all
         products and proceeds thereof, pursuant to the Borrower Security
         Agreement.

                  (b) The Borrower shall execute and cause to be executed such
         further documents and instruments, including without limitation,
         Uniform Commercial Code financing statements, as the Agent, in its
         sole discretion, deems necessary or desirable to evidence and perfect
         its Liens and security interests in the Collateral.

                  (c) The Borrower shall cause each present and future
         Subsidiary, excluding Newpark Shipbuilding and Repair, Inc., to
         guaranty the Obligations and to grant to the Agent for the benefit of
         the Banks a first priority and perfected security interest in the
         accounts receivable of such Subsidiary pursuant to a Guarantor
         Security Agreement.

         Section 5.2 Setoff.  If an Event of Default shall have occurred and is
continuing, each Bank is hereby authorized at any time and from time to time,
without notice to the Borrower (any

                                     - 19 -

<PAGE>   25



such notice being hereby expressly waived by the Borrower), 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 such Bank
to or for the credit or the account of the Borrower against any and all of the
obligations of the Borrower now or hereafter existing under this Agreement,
such Bank's Note, or any other Loan Document, irrespective of whether or not
the Agent or such Bank shall have made any demand under this Agreement or any
of such Bank's Notes or such other Loan Document and although such obligations
may be unmatured. Each Bank agrees promptly to notify the Borrower (with a copy
to the Agent) after any such setoff and application, provided that the failure
to give such notice shall not affect the validity of such setoff and
application. The rights and remedies of each Bank hereunder are in addition to
other rights and remedies (including, without limitation, other rights of
setoff) which such Bank may have.

                                   ARTICLE VI

         by the laws of the State of Texas or any other jurisdiction, by any of
         the Loan Documents, by equity, or otherwise.

Provided, however, that upon the occurrence of an Event of Default under
Subsection (d) or (e) of Section 14.1, the Total Commitment of all of the Banks
shall automatically terminate, and the outstanding principal of and accrued and
unpaid interest on the Notes and all other obligations of the Borrower under
the Loan Documents shall thereupon become immediately due and payable without
notice, demand, presentment, notice of dishonor, notice of acceleration, notice
of intent to accelerate, protest, or other formalities of any kind, all of
which are hereby expressly waived by the Borrower.

         Section 11.3 Cash Collateral. If any Event of Default shall occur and
be continuing, the Borrower shall, if requested by the Agent, immediately
deposit with and pledge to the Agent on behalf of the Banks cash or cash
equivalent investments in an amount equal to the outstanding Letter of Credit
Liabilities as security for the Obligations.

         Section 11.4 Performance by the Agent. If the Borrower shall fail to
perform any covenant or agreement in accordance with the terms of the Loan
Documents, the Agent may, at the direction of Required Banks, perform or
attempt to perform such covenant or agreement on behalf of the Borrower. In
such event, the Borrower shall, at the request of the Agent, promptly pay any
amount expended by the Agent or the Banks in connection with such performance
or attempted performance to the Agent at the Principal Office, together with
interest thereon at the Default Rate from and including the date of such
expenditure to but excluding the date such expenditure is paid in full.
Notwithstanding the foregoing, it is expressly agreed that neither the Agent
nor any Bank shall have any liability or responsibility for the performance of
any obligation of the Borrower under this Agreement or any of the other Loan
Documents.

                                  ARTICLE XII

                                   The Agent

         Section 12.1 Appointment, Powers and Immunities. In order to expedite
the various transactions contemplated by this agreement, the Banks hereby
irrevocably appoint and authorize SWBT to act as their Agent hereunder and
under each of the other Loan Documents. SWBT consents to such appointment and
agrees to perform the duties of the Agent as specified herein. The Banks
authorize and direct the Agent to take such action in their name and on their
behalf under the terms and provisions of the Loan Documents and to exercise
such rights and powers thereunder as are specifically delegated to or required
of the Agent for the Banks, together with such rights and powers as are
reasonably incidental thereto. The Agent is hereby expressly authorized to act
as the Agent on behalf of itself and the other Banks:

                  (a) To receive on behalf of each of the Banks any payment of
         principal, interest, fees or other amounts paid pursuant to this
         Agreement and the Notes and to distribute to each Bank its pro rata
         share of all payments so received as provided in this Agreement;

                  (b) To receive all documents and items to be furnished under
         the Loan Documents;


                                     - 37 -

<PAGE>   43



                  (c) To act as nominee for and on behalf of the Banks in and 
         under the Loan Documents;

                  (d) To arrange for the means whereby the funds of the Banks
         are to be made available to the Borrower;

                  (e) To distribute to the Banks information, requests,
         notices, payments, prepayments, documents and other items received
         from the Borrower, the other Obligated Parties, and other Persons;

                  (f) To execute and deliver to the Borrower, the other
         Obligated Parties, and other Persons, all requests, demands,
         approvals, notices, and consents received from the Banks;

                  (g) To the extent permitted by the Loan Documents, to
         exercise on behalf of each Bank all rights and remedies of Banks upon
         the occurrence of any Event of Default;

                  (h) To accept, execute, and deliver the Security Agreement
         and any other security documents as the secured party; and

                  (i) To take such other actions as may be requested by
         Required Banks.

         Neither the Agent nor any of its Affiliates, officers, directors,
employees, attorneys, or agents shall be liable for any action taken or omitted
to be taken by any of them hereunder or otherwise in connection with this
Agreement or any of the other Loan Documents except for its or their own gross
negligence or willful misconduct. Without limiting the generality of the
preceding sentence, the Agent (i) may treat the payee of any Note as the holder
thereof until the Agent receives written notice of the assignment or transfer
thereof signed by such payee and in form satisfactory to the Agent; (ii) shall
have no duties or responsibilities except those expressly set forth in this
Agreement and the other Loan Documents, and shall not by reason of this
Agreement or any other Loan Document be a trustee or fiduciary for any Bank;
(iii) shall not be required to initiate any litigation or collection
proceedings hereunder or under any other Loan Document except to the extent
requested by Required Banks; (iv) shall not be responsible to the Banks for any
recitals, statements, representations or warranties contained in this Agreement
or any other Loan Document, or any certificate or other document referred to or
provided for in, or received by any of them under, this Agreement or any other
Loan Document, or for the value, validity, effectiveness, enforceability, or
sufficiency of this Agreement or any other Loan Document or any other document
referred to or provided for herein or therein or for any failure by any Person
to perform any of its obligations hereunder or thereunder; (v) may consult with
legal counsel (including counsel for the Borrower), independent public
accountants, and other experts selected by it and shall not be liable for any
action taken or omitted to be taken in good faith by it in accordance with the
advice of such counsel, accountants, or experts; and (vi) shall incur no
liability under or in respect of any Loan Document by acting upon any notice,
consent, certificate, or other instrument or writing believed by it to be
genuine and signed or sent by the proper party or parties. As to any matters
not expressly provided for by this Agreement, the Agent shall in all cases be
fully protected in acting, or in refraining from acting, hereunder in

                                     - 38 -

<PAGE>   44



accordance with instructions signed by Required Banks, and such instructions of
Required Banks and any action taken or failure to act pursuant thereto shall be
binding on all of the Banks; provided, however, that the Agent shall not be
required to take any action which exposes the Agent to personal liability or
which is contrary to this Agreement or any other Loan Document or applicable
law.

         Section 12.2 Rights of Agent as a Bank. With respect to its
Commitment, the Advances made by it and the Note issued to it, SWBT in its
capacity as a Bank hereunder shall have the same rights and powers hereunder as
any other Bank and may exercise the same as though it were not acting as the
Agent, and the term "Bank" or "Banks" shall, unless the context otherwise
indicates, include the Agent in its individual capacity. The Agent and its
Affiliates may (without having to account therefor to any Bank) accept deposits
from, lend money to, act as trustee under indentures of, provide merchant
banking services to, and generally engage in any kind of business with the
Borrower, any of its Subsidiaries, any other Obligated Party, and any other
Person who may do business with or own securities of the Borrower, any
Subsidiary, or any other Obligated Party, all as if it were not acting as the
Agent and without any duty to account therefor to the Banks.

         Section 12.3 Sharing of Payments, Etc. If any Bank shall obtain any
payment of any principal of or interest on any Advance made by it under this
Agreement or payment of any other obligation under the Loan Documents then owed
by the Borrower or any other Obligated Party to such Bank, whether voluntary,
involuntary, through the exercise of any right of setoff, banker's lien,
counterclaim or similar right, or otherwise, in excess of its pro rata share,
such Bank shall promptly purchase from the other Banks participations in the
Advances held by them hereunder in such amounts, and make such other
adjustments from time to time as shall be necessary to cause such purchasing
Bank to share the excess payment ratably with each of the other Banks in
accordance with its pro rata portion thereof. To such end, all of the Banks
shall make appropriate adjustments among themselves (by the resale of
participations sold or otherwise) if all or any portion of such excess payment
is thereafter rescinded or must otherwise be restored. The Borrower agrees, to
the fullest extent it may effectively do so under applicable law, that any Bank
so purchasing a participation in the Advances made by the other Banks may
exercise all rights of setoff, banker's lien, counterclaim, or similar rights
with respect to such participation as fully as if such Bank were a direct
holder of Advances to the Borrower in the amount of such participation. Nothing
contained herein shall require any Bank to exercise any such right or shall
affect the right of any Bank to exercise, and retain the benefits of
exercising, any such right with respect to any other indebtedness or obligation
of the Borrower.

         Section 12.4 INDEMNIFICATION. THE BANKS HEREBY AGREE TO INDEMNIFY THE
AGENT FROM AND HOLD THE AGENT HARMLESS AGAINST (TO THE EXTENT NOT REIMBURSED
UNDER SECTIONS 13.1 AND 13.2, BUT WITHOUT LIMITING THE OBLIGATIONS OF THE
BORROWER UNDER SECTIONS 13.1 AND 13.2), RATABLY IN ACCORDANCE WITH THEIR
RESPECTIVE COMMITMENTS, ANY AND ALL LIABILITIES, OBLIGATIONS, LOSSES, DAMAGES,
PENALTIES, ACTIONS, JUDGMENTS, DEFICIENCIES, SUITS, COSTS, EXPENSES (INCLUDING
ATTORNEYS' FEES), AND DISBURSEMENTS OF ANY KIND OR NATURE WHATSOEVER WHICH MAY
BE IMPOSED ON, INCURRED BY, OR ASSERTED AGAINST THE AGENT IN ANY

<PAGE>   45



WAY RELATING TO OR ARISING OUT OF ANY OF THE LOAN DOCUMENTS OR ANY ACTION TAKEN
OR OMITTED TO BE TAKEN BY THE AGENT UNDER OR IN RESPECT OF ANY OF THE LOAN
DOCUMENTS; PROVIDED, FURTHER, THAT NO BANK SHALL BE LIABLE FOR ANY PORTION OF
THE FOREGOING TO THE EXTENT CAUSED BY THE AGENT'S GROSS NEGLIGENCE OR WILLFUL
MISCONDUCT. WITHOUT LIMITATION OF THE FOREGOING, IT IS THE EXPRESS INTENTION OF
THE BANKS THAT THE AGENT SHALL BE INDEMNIFIED HEREUNDER FROM AND HELD HARMLESS
AGAINST ALL OF SUCH LIABILITIES, OBLIGATIONS, LOSSES, DAMAGES, PENALTIES,
ACTIONS, JUDGMENTS, DEFICIENCIES, SUITS, COSTS, EXPENSES (INCLUDING ATTORNEYS'
FEES), AND DISBURSEMENTS OF ANY KIND OR NATURE DIRECTLY OR INDIRECTLY ARISING
OUT OF OR RESULTING FROM THE SOLE OR CONTRIBUTORY NEGLIGENCE OF THE AGENT.
WITHOUT LIMITING ANY OTHER PROVISION OF THIS SECTION, EACH BANK AGREES TO
REIMBURSE THE AGENT PROMPTLY UPON DEMAND FOR ITS PRO RATA SHARE (CALCULATED ON
THE BASIS OF THE SUM OF THE BANKS' COMMITMENTS) OF ANY AND ALL OUT-OF-POCKET
EXPENSES (INCLUDING REASONABLE ATTORNEYS' FEES) INCURRED BY THE AGENT IN
CONNECTION WITH THE PREPARATION, EXECUTION, DELIVERY, ADMINISTRATION,
MODIFICATION, AMENDMENT OR ENFORCEMENT (WHETHER THROUGH NEGOTIATIONS, LEGAL
PROCEEDINGS, OR OTHERWISE) OF, OR LEGAL ADVICE IN RESPECT OF RIGHTS OR
RESPONSIBILITIES UNDER, THE LOAN DOCUMENTS, TO THE EXTENT THAT THE AGENT IS NOT
REIMBURSED FOR SUCH EXPENSES BY THE BORROWER.

         Section 12.5 Independent Credit Decisions. Each Bank agrees that it
has independently and without reliance on the Agent or any other Bank, and
based on such documents and information as it has deemed appropriate, made its
own credit analysis of the Borrower and decision to enter into this Agreement
and that it will, independently and without reliance upon the Agent or any
other Bank, and based upon such documents and information as it shall deem
appropriate at the time, continue to make its own analysis and decisions in
taking or not taking action under this Agreement or any of the other Loan
Documents. The Agent shall not be required to keep itself informed as to the
performance or observance by the Borrower or any Obligated Party of this
Agreement or any other Loan Document or to inspect the properties or books of
the Borrower or any Obligated Party. Except for notices, reports and other
documents and information expressly required to be furnished to the Banks by
the Agent hereunder or under the other Loan Documents, the Agent shall not have
any duty or responsibility to provide any Bank with any credit or other
financial information concerning the affairs, financial condition or business
of the Borrower or any Obligated Party (or any of their Affiliates) which may
come into the possession of the Agent or any of its Affiliates.

         Section 12.6 Several Commitments. The Commitments and other
obligations of the Banks under this Agreement are several. The default by any
Bank in making an Advance in accordance with its respective Commitment shall
not relieve the other Banks of their obligations under this Agreement. In the
event of any default by any Bank in making any Advance, each nondefaulting Bank
shall be obligated to make its Advance but shall not be obligated to advance
the amount which the defaulting Bank was required to advance hereunder. In no
event shall any Bank be required to advance an amount or amounts which shall in
the aggregate exceed such

                                     - 40 -

<PAGE>   46



Bank's respective Commitment. No Bank shall be responsible for any act or
omission of any other Bank.

         Section 12.7 Successor Agent. Subject to the appointment and
acceptance of a successor Agent as provided below, the Agent may resign at any
time by giving notice thereof to the Banks and the Borrower and the Agent may
be removed at any time with or without cause by Required Banks. Upon any such
resignation or removal, Required Banks will have the right to appoint a
successor Agent. If no successor Agent shall have been so appointed by Required
Banks and shall have accepted such appointment within 30 days after the
retiring Agent's giving of notice of resignation or the Required Banks' removal
of the retiring Agent, then the retiring Agent may, on behalf of the Banks,
appoint a successor Agent, which shall be a commercial bank organized under the
laws of the United States of America or any State thereof and having combined
capital and surplus of at least $100,000,000. Upon the acceptance of its
appointment as successor Agent, such successor Agent shall thereupon succeed to
and become vested with all rights, powers, privileges, immunities, and duties
of the resigning or removed Agent, and the resigning or removed Agent shall be
discharged from its duties and obligations under this Agreement and the other
Loan Documents. After any Agent's resignation or removal as Agent, the
provisions of this Article XII shall continue in effect for its benefit in
respect of any actions taken or omitted to be taken by it while it was the
Agent.

                                  ARTICLE XIII

                                 Miscellaneous

         Section 13.1 Expenses. The Borrower hereby agrees to pay on demand:
(a) all costs and expenses of the Agent and the Banks in connection with the
preparation, negotiation, execution, and delivery of this Agreement and the
other Loan Documents and any and all amendments, modifications, renewals,
extensions, and supplements thereof and thereto, including, without limitation,
the reasonable fees and expenses of legal counsel for the Agent and the Banks,
(b) all costs and expenses of the Agent and the Banks in connection with any
Default and the enforcement of this Agreement or any other Loan Document,

other similar taxes, assessments, or charges levied by any Governmental

this Agreement or any other Loan Document, including, without limitation, all
costs, expenses, and other charges incurred in connection with obtaining any
audit, or appraisal in respect of the Collateral; provided that, unless a
Default or Event of Default has occurred or is continuing, the Borrower shall
not be required to pay for more than one annual field audit of accounts
receivable.

         Section 13.2      INDEMNIFICATION.  THE BORROWER SHALL INDEMNIFY THE
AGENT AND EACH BANK AND EACH AFFILIATE THEREOF AND THEIR RESPECTIVE
OFFICERS, DIRECTORS, EMPLOYEES, ATTORNEYS, AND AGENTS FROM, AND HOLD

                                     - 41 -

EACH OF THEM HARMLESS AGAINST, ANY AND ALL LOSSES, LIABILITIES, CLAIMS,
DAMAGES, PENALTIES, JUDGMENTS, DISBURSEMENTS, COSTS, AND EXPENSES (INCLUDING
ATTORNEYS' FEES) TO WHICH ANY OF THEM MAY BECOME SUBJECT WHICH DIRECTLY OR
INDIRECTLY ARISE FROM OR RELATE TO (A) THE NEGOTIATION, EXECUTION, DELIVERY,
PERFORMANCE, ADMINISTRATION, OR ENFORCEMENT OF ANY OF THE LOAN DOCUMENTS, (B)
ANY OF THE TRANSACTIONS CONTEMPLATED BY THE LOAN DOCUMENTS, (C) ANY BREACH BY
THE BORROWER OF ANY REPRESENTATION, WARRANTY, COVENANT, OR OTHER AGREEMENT
CONTAINED IN ANY OF THE LOAN DOCUMENTS, (D) THE PRESENCE, RELEASE, THREATENED
RELEASE, DISPOSAL, REMOVAL, OR CLEANUP OF ANY HAZARDOUS MATERIAL LOCATED ON,
ABOUT, WITHIN, OR AFFECTING ANY OF THE PROPERTIES OR ASSETS OF THE BORROWER OR
ANY SUBSIDIARY, (E) THE USE OR PROPOSED USE OF ANY LETTER OF CREDIT, (F) ANY
AND ALL TAXES, LEVIES, DEDUCTIONS, AND CHARGES IMPOSED ON THE LENDER OR ANY OF
THE LENDER'S CORRESPONDENTS IN RESPECT OF ANY LETTER OF CREDIT, OR (G) ANY
INVESTIGATION, LITIGATION, OR OTHER PROCEEDING, INCLUDING, WITHOUT LIMITATION,
ANY THREATENED INVESTIGATION, LITIGATION, OR OTHER PROCEEDING RELATING TO ANY
OF THE FOREGOING. WITHOUT LIMITING ANY PROVISION OF THIS AGREEMENT OR OF ANY
OTHER LOAN DOCUMENT, IT IS THE EXPRESS INTENTION OF THE PARTIES HERETO THAT
EACH PERSON TO BE INDEMNIFIED UNDER THIS SECTION SHALL BE INDEMNIFIED FROM AND
HELD HARMLESS AGAINST ANY AND ALL LOSSES, LIABILITIES, CLAIMS, DAMAGES,
PENALTIES, JUDGMENTS, DISBURSEMENTS, COSTS, AND EXPENSES (INCLUDING ATTORNEYS'
FEES) ARISING OUT OF OR RESULTING FROM THE SOLE OR CONTRIBUTORY NEGLIGENCE OF
SUCH PERSON BUT NOT ARISING OUT OF OR RESULTING FROM THE GROSS NEGLIGENCE OR
WILLFUL MISCONDUCT OF SUCH PERSON.

         Section 13.3 Limitation of Liability. None of the Agent, any Bank, or
any Affiliate, officer, director, employee, attorney, or agent thereof shall
have any liability with respect to, and the Borrower hereby waives, releases,
and agrees not to sue any of them upon, any claim for any special, indirect,
incidental, or consequential damages suffered or incurred by the Borrower in
connection with, arising out of, or in any way related to, this Agreement or
any of the other Loan Documents, or any of the transactions contemplated by
this Agreement or any of the other Loan Documents. The Borrower hereby waives,
releases, and agrees not to sue the Agent or any Bank or any of their
respective Affiliates, officers, directors, employees, attorneys, or agents for
punitive damages in respect of any claim in connection with, arising out of, or
in any way related to, this Agreement or any of the other Loan Documents, or
any of the transactions contemplated by this Agreement or any of the other Loan
Documents.

         Section 13.4 No Duty. All attorneys, accountants, appraisers, and
other professional Persons and consultants retained by the Agent and the Banks
shall have the right to act exclusively in the interest of the Agent and the
Banks and shall have no duty of disclosure, duty of loyalty, duty of care, or
other duty or obligation of any type or nature whatsoever to the Borrower or
any of the Borrower's shareholders or any other Person.

<PAGE>   48



         Section 13.5 No Fiduciary Relationship. The relationship between the
Borrower and each Bank is solely that of debtor and creditor, and neither the
Agent nor any Bank has any fiduciary or other special relationship with the
Borrower, and no term or condition of any of the Loan Documents shall be
construed so as to deem the relationship between the Borrower and any Bank to
be other than that of debtor and creditor.

         Section 13.6 Equitable Relief. The Borrower recognizes that in the
event the Borrower fails to pay, perform, observe, or discharge any or all of
the Obligations, any remedy at law may prove to be inadequate relief to the
Agent and the Banks. The Borrower therefore agrees that the Agent and the
Banks, if the Agent or the Banks so request, shall be entitled to temporary and
permanent injunctive relief in any such case without the necessity of proving
actual damages.

         Section 13.7 No Waiver; Cumulative Remedies. No failure on the part of
the Agent or any Bank to exercise and no delay in exercising, and no course of
dealing with respect to, any right, power, or privilege under this Agreement
shall operate as a waiver thereof, nor shall any single or partial exercise of
any right, power, or privilege under this Agreement preclude any other or
further exercise thereof or the exercise of any other right, power, or
privilege. The rights and remedies provided for in this Agreement and the other
Loan Documents are cumulative and not exclusive of any rights and remedies
provided by law.

         Section 13.8 Successors and Assigns.

                  (a) This Agreement shall be binding upon and inure to the
         benefit of the parties hereto and their respective successors and
         assigns. The Borrower may not assign or transfer any of its rights or
         obligations hereunder without the prior written consent of the Agent
         and all of the Banks. Any Bank may sell participations to one or more
         banks or other institutions in or to all or a portion of its rights
         and obligations under this Agreement and the other Loan Documents
         (including, without limitation, all or a portion of its Commitments
         and the Advances owing to it); provided, however, that (i) such Bank's
         obligations under this Agreement and the other Loan Documents
         (including, without limitation, its Commitment) shall remain
         unchanged, (ii) such Bank shall remain solely responsible to the
         Borrower for the performance of such obligations, (iii) such Bank
         shall remain the holder of its Note for all purposes of this
         Agreement, (iv) the Borrower shall continue to deal solely and
         directly with such Bank in connection with such Bank's rights and
         obligations under this Agreement and the other Loan Documents, and (v)
         such Bank shall not sell a participation that conveys to the
         participant the right to vote or give or withhold consents under this
         Agreement or any other Loan Document, other than the right to vote
         upon or consent to (A) any increase of such Bank's Commitment, (B) any
         reduction of the principal amount of, or interest to be paid on, the
         Advances of such Bank, (C) any reduction of any commitment fee or
         other amount payable to such Bank under any Loan Document, or (D) any
         postponement of any date for the payment of any amount payable in
         respect of the Advances of such Bank.

                  (b) The Borrower and each of the Banks agree that any Bank
         (the "Assigning Bank") may at any time assign to one or more Eligible
         Assignees all, or a proportionate part of all, of its rights and
         obligations under this Agreement and the other Loan

                                     - 43 -

<PAGE>   49



         Documents (including, without limitation, its Commitment and Advances)
         (each an "Assignee"); provided, however, that (i) each such assignment
         shall be of a consistent, and not a varying, percentage of all of the
         assigning Bank's rights and obligations under this Agreement and the
         other Loan Documents, (ii) except in the case of an assignment of all
         of a Bank's rights and obligations under this Agreement and the other
         Loan Documents, the amount of the Commitment of the assigning Bank
         being assigned pursuant to each assignment (determined as of the date
         of the Assignment Acceptance with respect to such assignment) shall in
         no event be less than $2,500,000, and (iii) the parties to each such
         assignment shall execute and deliver to the Agent for its acceptance
         and recording in the Register (as defined below), an Assignment and
         Acceptance, together with the Note subject to such assignment, and a
         processing and recordation fee of $3,500. Upon such execution,
         delivery, acceptance, and recording, from and after the effective date
         specified in each Assignment and Acceptance, which effective date
         shall be at least five Business Days after the execution thereof, or,
         if so specified in such Assignment and Acceptance, the date of
         acceptance thereof by the Agent, (x) the assignee thereunder shall be
         a party hereto as a "Bank" and, to the extent that rights and
         obligations hereunder have been assigned to it pursuant to such
         Assignment and Acceptance, have the rights and obligations of a Bank
         hereunder and under the Loan Documents and (y) the Bank that is an
         assignor thereunder shall, to the extent that rights and obligations
         hereunder have been assigned by it pursuant to such Assignment and
         Acceptance, relinquish its rights and be released from its obligations
         under this Agreement and the other Loan Documents (and, in the case of
         an Assignment and Acceptance covering all or the remaining portion of
         a Bank's rights and obligations under the Loan Documents, such Bank
         shall cease to be a party thereto).

                  (c) By executing and delivering an Assignment and Acceptance,
         the Bank that is an assignor thereunder and the assignee thereunder
         confirm to and agree with each other and the other parties hereto as
         follows: (i) other than as provided in such Assignment and Acceptance,
         such assigning Bank makes no representation or warranty and assumes no
         responsibility with respect to any statements, warranties, or
         representations made in or in connection with the Loan Documents or
         the execution, legality, validity, and enforceability, genuineness,
         sufficiency, or value of the Loan Documents or any other instrument or
         document furnished pursuant thereto; (ii) such assigning Bank makes no
         representation or warranty and assumes no responsibility with respect
         to the financial condition of the Borrower or any Obligated Party or
         the performance or observance by the Borrower or any Obligated Party
         of its obligations under the Loan Documents; (iii) such assignee
         confirms that it has received a copy of the other Loan Documents,
         together with copies of the financial statements referred to in
         Section 7.2 and such other documents and information as it has deemed
         appropriate to make its own credit analysis and decision to enter into
         such Assignment and Acceptance; (iv) such assignee will, independently
         and without reliance upon the Agent or such assignor and based on such
         documents and information as it shall deem appropriate at the time,
         continue to make its own credit decisions in taking or not taking
         action under this Agreement and the other Loan Documents; (v) such
         assignee confirms that it is an Eligible Assignee; (vi) such assignee
         appoints and authorizes the Agent to take such action as agent on its
         behalf and exercise such powers under the Loan Documents as are

         delegated to the Agent by the terms thereof, together with such powers
         as are reasonably incidental thereto; and (vii) such assignee agrees
         that it will perform in accordance with their terms all of the
         obligations which by the terms of the Loan Documents are required to
         be performed by it as a Bank.

                  (d) The Agent shall maintain at its Principal Office a copy
         of each Assignment and Acceptance delivered to and accepted by it and
         a register for the recordation of the names and addresses of the Banks
         and the Commitment of, and principal amount of the Advances owing to,
         each Bank from time to time (the "Register"). The entries in the
         Register shall be conclusive and binding for all purposes, absent
         manifest error, and the Borrower, the Agent, and the Banks may treat
         each Person whose name is recorded in the Register as a Bank hereunder
         for all purposes under the Loan Documents. The Register shall be
         available for inspection by the Borrower or any Bank at any reasonable
         time and from time to time upon reasonable prior notice.

                  (e) Upon its receipt of an Assignment and Acceptance executed
         by an assigning Bank and assignee representing that it is an Eligible
         Assignee, together with any Note subject to such assignment, the Agent
         shall, if such Assignment and Acceptance has been completed and is in
         substantially the form of Exhibit "E" hereto, (i) accept such
         Assignment and Acceptance, (ii) record the information contained
         therein in the Register, and (iii) give prompt written notice thereof
         to the Borrower. Within five Business Days after its receipt of such
         notice, the Borrower, at its expense, shall execute and deliver to the
         Agent in exchange for the surrendered Note or Notes, a new Note or
         Notes to the order of such Eligible Assignee in an amount equal to the
         Commitment assumed by it pursuant to such Assignment and Acceptance
         and, if the assigning Bank has retained a Commitment, a new Note or
         Notes to the order of the assigning Bank in an amount equal to the
         Commitment retained by it hereunder (each such promissory note shall
         constitute a "Note" for purposes of the Loan Documents). Such new
         Notes shall be in an aggregate principal amount of the surrendered
         Note or Notes, shall be dated the effective date of such Assignment
         and Acceptance, and shall otherwise be in substantially the form of
         Exhibit "A" hereto.

                  (f) Any Bank may, in connection with any assignment or
         participation or proposed assignment or participation pursuant to this
         Section, disclose to the assignee or participant or proposed assignee
         or participant, any information relating to the Borrower or its
         Subsidiaries furnished to such Bank by or on behalf of the Borrower or
         its Subsidiaries.

         Section 13.9 Survival. All representations and warranties made in this
Agreement or any other Loan Document or in any document, statement, or
certificate furnished in connection with this Agreement shall survive the
execution and delivery of this Agreement and the other Loan Documents, and no
investigation by the Agent or any Bank or any closing shall affect the
representations and warranties or the right of the Agent or any Bank to rely
upon them. Without prejudice to the survival of any other obligation of the
Borrower hereunder, the obligations of the Borrower under Article IV and
Sections 12.1 and 12.2 shall survive repayment of the Notes and termination of
the Commitments.

         Section 13.10 Amendments, Etc. No amendment or waiver of any provision
of this Agreement, the Notes, or any other Loan Document to which the Borrower
is a party, nor any consent to any departure by the Borrower therefrom, shall
in any event be effective unless the same shall be agreed or consented to by
Required Banks and the Borrower, and each such waiver or consent shall be
effective only in the specific instance and for the specific purpose for which
given; provided, that no amendment, waiver, or consent shall, unless in writing
and signed by all of the Banks and the Borrower, do any of the following: (a)
increase Commitments of the Banks or subject the Banks to any additional
obligations; (b) reduce the principal of, or interest on, the Notes or any fees
or other amounts payable hereunder; (c) postpone any date fixed for any payment
of principal of, or interest on, the Notes or any fees or other amounts payable
hereunder; (d) waive any of the conditions specified in Article III; (e) change
the percentage of the Commitments or of the aggregate unpaid principal amount
of the Notes or the number of Banks which shall be required for the Banks or
any of them to take any action under this Agreement; (f) change any provision
contained in this Section 13.10; or (g) release any Collateral. Notwithstanding
anything to the contrary contained in this Section, no amendment, waiver, or
consent shall be made with respect to Article XIII hereof without the prior
written consent of the Agent.

         Section 13.11 Maximum Interest Rate. No provision of this Agreement or
of any other Loan Document shall require the payment or the collection of
interest in excess of the maximum amount permitted by applicable law. If any
excess of interest in such respect is hereby provided for, or shall be
adjudicated to be so provided, in any Loan Document or otherwise in connection
with this loan transaction, the provisions of this Section shall govern and
prevail and neither the Borrower nor the sureties, guarantors, successors, or
assigns of the Borrower shall be obligated to pay the excess amount of such
interest or any other excess sum paid for the use, forbearance, or detention of
sums loaned pursuant hereto. In the event any Bank ever receives, collects, or
applies as interest any such sum, such amount which would be in excess of the
maximum amount permitted by applicable law shall be applied as a payment and
reduction of the principal of the indebtedness evidenced by the Notes; and, if
the principal of the Notes has been paid in full, any remaining excess shall
forthwith be paid to the Borrower. In determining whether or not the interest
paid or payable exceeds the Maximum Rate, the Borrower and each Bank shall, to
the extent permitted by applicable law, (a) characterize any non-principal
payment as an expense, fee, or premium rather than as interest, (b) exclude
voluntary prepayments and the effects thereof, and (c) amortize, prorate,
allocate, and spread in equal or unequal parts the total amount of interest
throughout the entire contemplated term of the indebtedness evidenced by the
Notes so that interest for the entire term does not exceed the Maximum Rate.

         Section 13.12 Notices. All notices and other communications provided
for in this Agreement and the other Loan Documents to which the Borrower is a
party shall be given or made by telex, telegraph, telecopy, cable, or in
writing and telexed, telecopied, telegraphed, cabled, mailed by certified mail
return receipt requested, or delivered to the intended recipient at the
"Address for Notices" specified below its name on the signature pages hereof;
or, as to any party at such other address as shall be designated by such party
in a notice to each other party given in accordance with this Section. Except
as otherwise provided in this Agreement, all such communications shall be
deemed to have been duly given when transmitted by telex or telecopy, subject
to telephone confirmation of receipt, or delivered to the telegraph or cable
office, subject

                                     - 46 -

to telephone confirmation of receipt, or when personally delivered or, in the
case of a mailed notice, when duly deposited in the mails, in each case given
or addressed as aforesaid; provided, however, notices to the Agent pursuant to
Article II shall not be effective until received by the Agent.

         Section 13.13 Governing Law; Venue; Service of Process. This Agreement
shall be governed by and construed in accordance with the laws of the State of
Texas and the applicable laws of the United States of America. This Agreement
has been entered into in Harris County, Texas, and it shall be performable for
all purposes in Harris County, Texas. Any action or proceeding against the
Borrower under or in connection with any of the Loan Documents may be brought
in any state or federal court in Harris County, Texas. The Borrower hereby
irrevocably (a) submits to the nonexclusive jurisdiction of such courts, and
(b) waives any objection it may now or hereafter have as to the venue of any
such action or proceeding brought in any such court or that any such court is
an inconvenient forum. The Borrower agrees that service of process upon it may
be made by certified or registered mail, return receipt requested, at its
address specified or determined in accordance with the provisions of Section
13.12. Nothing herein or in any of the other Loan Documents shall affect the
right of the Agent or any Bank to serve process in any other manner permitted
by law or shall limit the right of the Agent or any Bank to bring any action or
proceeding against the Borrower or with respect to any of its property in
courts in other jurisdictions. Any action or proceeding by the Borrower against
the Agent or any Bank shall be brought only in a court located in Harris
County, Texas.

         Section 13.14 Counterparts. This Agreement may be executed in one or
more counterparts, each of which shall be deemed an original, but all of which
together shall constitute one and the same instrument.

         Section 13.15 Severability. Any provision of this Agreement held by a
court of competent jurisdiction to be invalid or unenforceable shall not impair
or invalidate the remainder of this Agreement and the effect thereof shall be
confined to the provision held to be invalid or illegal.

         Section 13.16 Headings.  The headings, captions, and arrangements used 
in this Agreement are for convenience only and shall not affect the
interpretation of this Agreement.

         Section 13.17 Non-Application of Chapter 346 of Texas Finance Code.
The provisions of Chapter 346 of the Texas Finance Code (Vernon's Texas Code
Annotated) are specifically declared by the parties hereto not to be applicable
to this Agreement or any of the other Loan Documents or to the transactions
contemplated hereby.

         Section 13.18 Construction. The Borrower, the Agent, and each Bank
acknowledges that each of them has had the benefit of legal counsel of its own
choice and has been afforded an opportunity to review this Agreement and the
other Loan Documents with its legal counsel and that this Agreement and the
other Loan Documents shall be construed as if jointly drafted by the parties
hereto.

         Section 13.19 Independence of Covenants. All covenants hereunder shall
be given independent effect so that if a particular action or condition is not
permitted by any of such covenants, the fact that it would be permitted by an
exception to, or be otherwise within the limitations of, another covenant shall
not avoid the occurrence of a Default if such action is taken or such condition
exists.

         Section 13.20 WAIVER OF JURY TRIAL. TO THE FULLEST EXTENT PERMITTED BY
APPLICABLE LAW, EACH OF THE PARTIES HERETO HEREBY IRREVOCABLY AND EXPRESSLY
WAIVES ALL RIGHT TO A TRIAL BY JURY IN ANY ACTION, PROCEEDING, OR COUNTERCLAIM
(WHETHER BASED UPON CONTRACT, TORT, OR OTHERWISE) ARISING OUT OF OR RELATING TO
ANY OF THE LOAN DOCUMENTS OR THE TRANSACTIONS CONTEMPLATED THEREBY OR THE
ACTIONS OF THE AGENT OR ANY BANK IN THE NEGOTIATION, ADMINISTRATION, OR
ENFORCEMENT THEREOF.

         Section 13.21     ARBITRATION.

                  (a) ARBITRATION. NOTWITHSTANDING ANY PROVISION IN ANY LOAN
         DOCUMENT TO THE CONTRARY, UPON THE DEMAND OF ANY PARTY, ANY DISPUTE
         SHALL BE RESOLVED BY BINDING ARBITRATION (EXCEPT AS SET FORTH IN (E)
         BELOW) IN ACCORDANCE WITH THE TERMS OF THIS AGREEMENT. A "DISPUTE"
         SHALL MEAN ANY ACTION, DISPUTE, CLAIM OR CONTROVERSY OF ANY KIND,
         WHETHER IN CONTRACT OR TORT, STATUTORY OR COMMON LAW, LEGAL OR
         EQUITABLE, NOW EXISTING OR HEREAFTER ARISING UNDER OR IN CONNECTION
         WITH, OR IN ANY WAY PERTAINING TO, ANY OF THE LOAN DOCUMENTS, OR ANY
         PAST, PRESENT OR FUTURE EXTENSIONS OF CREDIT AND OTHER ACTIVITIES,
         TRANSACTIONS OR OBLIGATIONS OF ANY KIND RELATED DIRECTLY OR INDIRECTLY
         TO ANY OF THE LOAN DOCUMENTS, INCLUDING WITHOUT LIMITATION, ANY OF THE
         FOREGOING ARISING IN CONNECTION WITH THE EXERCISE OF ANY SELF-HELP,
         ANCILLARY OR OTHER REMEDIES PURSUANT TO ANY OF THE LOAN DOCUMENTS. ANY
         PARTY MAY BY SUMMARY PROCEEDINGS BRING AN ACTION IN COURT TO COMPEL
         ARBITRATION OF A DISPUTE. ANY PARTY WHO FAILS OR REFUSES TO SUBMIT TO
         ARBITRATION FOLLOWING A LAWFUL DEMAND BY ANY OTHER PARTY SHALL BEAR
         ALL COSTS AND EXPENSES INCURRED BY SUCH OTHER PARTY IN COMPELLING
         ARBITRATION OF ANY DISPUTE.

                  (b) GOVERNING RULES. ARBITRATION PROCEEDINGS SHALL BE
         ADMINISTERED BY THE AMERICAN ARBITRATION ASSOCIATION ("AAA") OR SUCH
         OTHER ADMINISTRATOR AS THE PARTIES SHALL MUTUALLY AGREE UPON IN
         ACCORDANCE WITH THE AAA COMMERCIAL ARBITRATION RULES. ALL DISPUTES
         SUBMITTED TO ARBITRATION SHALL BE RESOLVED IN ACCORDANCE WITH THE
         FEDERAL ARBITRATION ACT (TITLE 9 OF THE UNITED STATES CODE),
         NOTWITHSTANDING ANY CONFLICTING CHOICE OF LAW PROVISION IN ANY OF THE
         LOAN DOCUMENTS. THE ARBITRATION

                                     - 48 -

<PAGE>   54



         SHALL BE CONDUCTED AT A LOCATION IN TEXAS SELECTED BY THE AAA OR OTHER
         ADMINISTRATOR. IF THERE IS ANY INCONSISTENCY BETWEEN THE TERMS HEREOF
         AND ANY SUCH RULES, THE TERMS AND PROCEDURES SET FORTH HEREIN SHALL
         CONTROL. ALL STATUTES OF LIMITATION APPLICABLE TO ANY DISPUTE SHALL
         APPLY TO ANY ARBITRATION PROCEEDING. ALL DISCOVERY ACTIVITIES SHALL BE
         EXPRESSLY LIMITED TO MATTERS DIRECTLY RELEVANT TO THE DISPUTE BEING
         ARBITRATED. JUDGMENT UPON ANY AWARD RENDERED IN AN ARBITRATION MAY BE
         ENTERED IN ANY COURT HAVING JURISDICTION; PROVIDED HOWEVER, THAT
         NOTHING CONTAINED HEREIN SHALL BE DEEMED TO BE A WAIVER BY ANY PARTY
         THAT IS A BANK OF THE PROTECTIONS AFFORDED TO IT UNDER 12 U.S.C.
         SECTION 91 OR ANY SIMILAR APPLICABLE STATE LAW.

                  (c) NO WAIVER; PROVISIONAL REMEDIES, SELF-HELP AND
         FORECLOSURE. NO PROVISION HEREOF SHALL LIMIT THE RIGHT OF ANY PARTY TO
         EXERCISE SELF-HELP REMEDIES SUCH AS SETOFF, FORECLOSURE AGAINST OR
         SALE OF ANY REAL OR PERSONAL PROPERTY COLLATERAL OR SECURITY, OR TO
         OBTAIN PROVISIONAL OR ANCILLARY REMEDIES, INCLUDING WITHOUT LIMITATION
         INJUNCTIVE RELIEF, SEQUESTRATION, ATTACHMENT, GARNISHMENT OR THE
         APPOINTMENT OF A RECEIVER, FROM A COURT OF COMPETENT JURISDICTION
         BEFORE, AFTER OR DURING THE PENDENCY OF ANY ARBITRATION OR OTHER
         PROCEEDING. THE EXERCISE OF ANY SUCH REMEDY SHALL NOT WAIVE THE RIGHT
         OF ANY PARTY TO COMPEL ARBITRATION HEREUNDER.

                  (d) ARBITRATOR QUALIFICATIONS AND POWERS; AWARDS. ARBITRATORS
         MUST BE ACTIVE MEMBERS OF THE TEXAS STATE BAR WITH EXPERTISE IN THE
         SUBSTANTIVE LAWS APPLICABLE TO THE SUBJECT MATTER OF THE DISPUTE.
         ARBITRATORS ARE EMPOWERED TO RESOLVE DISPUTES BY SUMMARY RULINGS IN
         RESPONSE TO MOTIONS FILED PRIOR TO THE FINAL ARBITRATION HEARING.
         ARBITRATORS (I) SHALL RESOLVE ALL DISPUTES IN ACCORDANCE WITH THE
         SUBSTANTIVE LAW OF THE STATE OF TEXAS, (II) MAY GRANT ANY REMEDY OR
         RELIEF THAT A COURT OF THE STATE OF TEXAS COULD ORDER OR GRANT WITHIN
         THE SCOPE HEREOF AND SUCH ANCILLARY RELIEF AS IS NECESSARY TO MAKE
         EFFECTIVE ANY AWARD, AND (III) SHALL HAVE THE POWER TO AWARD RECOVERY
         OF ALL COSTS AND FEES, TO IMPOSE SANCTIONS AND TO TAKE SUCH OTHER
         ACTIONS AS THEY DEEM NECESSARY TO THE SAME EXTENT A JUDGE COULD
         PURSUANT TO THE FEDERAL RULES OF CIVIL PROCEDURE, THE TEXAS RULES OF
         CIVIL PROCEDURE OR OTHER APPLICABLE LAW. ANY DISPUTE IN WHICH THE
         AMOUNT IN CONTROVERSY IS $5,000,000 OR LESS SHALL BE DECIDED BY A
         SINGLE ARBITRATOR WHO SHALL NOT RENDER AN AWARD OF GREATER THAN
         $5,000,000 (INCLUDING DAMAGES, COSTS, FEES AND EXPENSES). BY
         SUBMISSION TO A SINGLE ARBITRATOR, EACH PARTY EXPRESSLY WAIVES ANY
         RIGHT OR CLAIM TO RECOVER MORE THAN $5,000,000. ANY DISPUTE IN WHICH
         THE AMOUNT IN

                                     - 49 -

<PAGE>   55



         CONTROVERSY EXCEEDS $5,000,000 SHALL BE DECIDED BY MAJORITY VOTE OF A
         PANEL OF THREE ARBITRATORS; PROVIDED HOWEVER, THAT ALL THREE
         ARBITRATORS MUST ACTIVELY PARTICIPATE IN ALL HEARINGS AND
         DELIBERATIONS.

                  (e) JUDICIAL REVIEW. NOTWITHSTANDING ANYTHING HEREIN TO THE
         CONTRARY, IN ANY ARBITRATION IN WHICH THE AMOUNT IN CONTROVERSY
         EXCEEDS $25,000,000, THE ARBITRATORS SHALL BE REQUIRED TO MAKE
         SPECIFIC, WRITTEN FINDINGS OF FACT AND CONCLUSIONS OF LAW. IN SUCH
         ARBITRATIONS (I) THE ARBITRATORS SHALL NOT HAVE THE POWER TO MAKE ANY
         AWARD WHICH IS NOT SUPPORTED BY SUBSTANTIAL EVIDENCE OR WHICH IS BASED
         ON LEGAL ERROR, (II) AN AWARD SHALL NOT BE BINDING UPON THE PARTIES
         UNLESS THE FINDINGS OF FACT ARE SUPPORTED BY SUBSTANTIAL EVIDENCE AND
         THE CONCLUSIONS OF LAW ARE NOT ERRONEOUS UNDER THE SUBSTANTIVE LAW OF
         THE STATE OF TEXAS, AND (III) THE PARTIES SHALL HAVE IN ADDITION TO
         THE GROUNDS REFERRED TO IN THE FEDERAL ARBITRATION ACT FOR VACATING,
         MODIFYING OR CORRECTING AN AWARD THE RIGHT TO JUDICIAL REVIEW OF (A)
         WHETHER THE FINDINGS OF FACT RENDERED BY THE ARBITRATORS ARE SUPPORTED
         BY SUBSTANTIAL EVIDENCE, AND (B) WHETHER THE CONCLUSIONS OF LAW ARE
         ERRONEOUS UNDER THE SUBSTANTIVE LAW OF THE STATE OF TEXAS. JUDGMENT
         CONFIRMING AN AWARD IN SUCH A PROCEEDING MAY BE ENTERED ONLY IF A
         COURT DETERMINES THE AWARD IS SUPPORTED BY SUBSTANTIAL EVIDENCE AND
         NOT BASED ON LEGAL ERROR UNDER THE SUBSTANTIVE LAW OF THE STATE OF
         TEXAS.

                  (f) MISCELLANEOUS. TO THE MAXIMUM EXTENT PRACTICABLE, THE
         AAA, THE ARBITRATORS AND THE PARTIES SHALL TAKE ALL ACTION REQUIRED TO
         CONCLUDE ANY ARBITRATION PROCEEDING WITHIN 180 DAYS OF THE FILING OF
         THE DISPUTE WITH THE AAA. NO ARBITRATOR OR OTHER PARTY TO AN
         ARBITRATION PROCEEDING MAY DISCLOSE THE EXISTENCE, CONTENT OR RESULTS
         THEREOF, EXCEPT FOR DISCLOSURES OF INFORMATION BY A PARTY REQUIRED IN
         THE ORDINARY COURSE OF ITS BUSINESS, BY APPLICABLE LAW OR REGULATION,
         OR TO THE EXTENT NECESSARY TO EXERCISE ANY JUDICIAL REVIEW RIGHTS SET
         FORTH HEREIN. IF MORE THAN ONE AGREEMENT FOR ARBITRATION BY OR BETWEEN
         THE PARTIES POTENTIALLY APPLIES TO A DISPUTE, THE ARBITRATION
         PROVISION MOST DIRECTLY RELATED TO THE LOAN DOCUMENTS OR THE SUBJECT
         MATTER OF THE DISPUTE SHALL CONTROL. THIS ARBITRATION PROVISION SHALL
         SURVIVE TERMINATION, AMENDMENT OR EXPIRATION OF ANY OF THE LOAN
         DOCUMENTS OR ANY RELATIONSHIP BETWEEN THE PARTIES.

         Section 13.22 NO ORAL AGREEMENTS.  THIS AGREEMENT, THE NOTES, AND
THE OTHER LOAN DOCUMENTS REFERRED TO HEREIN PRESENT THE FINAL

                                     - 50 -

AGREEMENT AMONG THE PARTIES HERETO AND MAY NOT BE CONTRADICTED OR
VARIED BY EVIDENCE OF PRIOR, CONTEMPORANEOUS, OR SUBSEQUENT ORAL
AGREEMENTS OF THE PARTIES HERETO.  THERE ARE NO UNWRITTEN ORAL
AGREEMENTS AMONG THE PARTIES HERETO.
