                          ROHR, INC.  AND SUBSIDIARIES
         NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS  -  (UNAUDITED)

    The consolidated balance sheet as of May 1, 1994, and statements of
    operations for the three month and nine month periods ended May 1, 1994 and
    May 2, 1993, and cash flows for the nine month periods ended May 1, 1994,
    and May 2, 1993, reflect all adjustments (consisting only of normal
    recurring adjustments) which are, in the opinion of management, necessary
    for a fair presentation of the results of operations for the interim
    periods.  Financial results for interim periods are not necessarily
    indicative of results to be expected for the full year.

    Certain information and footnote disclosures normally included in financial
    statements prepared in accordance with generally accepted accounting
    principles have been condensed or omitted.  These consolidated financial
    statements should be read in conjunction with the financial statements
    included in the July 31, 1993 Form 10-K.

    CONTINGENCIES

    In June 1987, the U.S. District Court of Los Angeles, in U.S. et al, vs.
    Stringfellow, granted partial summary judgment against the Company and 14
    other defendants on the issue of liability under the Comprehensive
    Environmental Response, Compensation and Liability Act ("CERCLA").  This
    suit alleges that the defendants are jointly and severally liable for all
    damage in connection with the Stringfellow hazardous waste disposal site in
    Riverside County, California.  In June 1989, a federal jury and a special
    master appointed by the federal court found the State of California also
    liable for the cleanup costs.  On November 30, 1993, the special master
    released his "Findings of Fact, Conclusions of Law and Reporting
    Recommendations of the Special Master Regarding the State Share Fact Finding
    Hearing".  In it, he allocated liability between the State of California and
    other parties.  As this hearing did not involve the valuation of future
    tasks and responsibilities, the order did not specify dollar amounts of
    liability.  The order, phrased in percentages of liability, recommended
    allocating liability on the CERCLA claims as follows:  65% to the State of
    California and 10% to the Stringfellow entities, leaving 25% to the
    generator/counterclaimants (including the Company) and other users of the
    site (or a maximum of up to 28% depending on the allocation of any
    Stringfellow entity orphan share).  On the state law claims, the special
    master recommended a 95% share for the State of California, and 5% for the
    Stringfellow entities, leaving 0% for the generator/counterclaimants.  This
    special master's finding is subject to a final decision and appeal.  The
    Company and the other generators of wastes disposed at the Stringfellow
    site,

                                  Page 5 of 17
<PAGE>
 
    which include numerous companies with assets and equity significantly
    greater than the Company, are jointly and severally liable for the share of
    cleanup costs for which the generators, as a group, may ultimately be found
    to be responsible.  Notwithstanding, this CERCLA liability is sometimes
    allocated among hazardous waste generators who used a waste disposal site
    based on the volume of hazardous waste they disposed at the site.  The
    Company is the second largest generator of wastes by volume disposed at the
    site, although it and certain other generators have argued the final
    allocation of cleanup costs among generators should not be determined solely
    by volume.  The largest volume generator of wastes disposed at the
    Stringfellow site has indicated it is significantly dependent on insurance
    to fund its share of any cleanup costs, and that it is in litigation with
    certain of its insurers.

    The Company has claims against its comprehensive general liability insurers
    for reimbursement of its cleanup costs at the site.  These claims are the
    subject of separate litigation, although the insurers nevertheless are
    paying substantially all of the Company's costs of defense in the CERCLA and
    State actions against the generators of wastes disposed at the site.
    Certain of these insurance policies have pollution exclusion clauses which
    are being argued as a defense and the insurers are alleging various other
    defenses to coverage.  The Company has entered settlements with some of the
    insurance carriers and is engaged in settlement discussions with certain
    others.

    The Company intends to continue to vigorously defend itself in the
    Stringfellow matter and believes, based upon currently available
    information, that the ultimate resolution will not have a material adverse
    effect on the financial position, liquidity, or results of operations of the
    Company.

    The Company is also involved in several other proceedings and investigations
    related to environmental protection matters.  It is difficult to estimate
    the ultimate level of environmental expenditures that will be required in
    connection with these matters due to a number of uncertainties, including
    the complexity of the related laws and their interpretation, alternative
    cleanup technologies and methods, insurance and other recoveries, and in
    some cases, the extent and uncertainties of the Company's involvement.
    However, the Company has heard of preliminary estimates of cleanup costs for
    the Rio Bravo, Chatham Brothers and Casmalia waste disposal sites as
    approximately $7 million, $30 million and $70 million, respectively, and the
    Company's share (based on estimated, respective volumes of discharges into
    such sites by all generators, all of which cannot now be known with
    certainty) could approximate $0.5 million for the Rio Bravo site, $0 for the
    Chatham Brothers site (based on the Company's belief that it never used that
    site), and $1.8 million for the Casmalia site.  The Company does not yet
    know

                                  Page 6 of 17
<PAGE>
 
    about the ability of all of the other waste generators using the Casmalia
    and Rio Bravo sites to fund their allocable share, and the Company could be
    found jointly or severally liable with all waste generators using such
    sites.  The Company has made claims against its insurance carriers for
    certain of these items, and has received claims acknowledgment letters
    reserving the rights of such carriers.  The insurers have alleged or may
    allege various defenses to coverage, although no litigation has been
    commenced.  Based upon presently available information, the Company believes
    that capital expenditures and costs of remedial actions in relation to these
    other matters will not have a material adverse effect on the financial
    position or results of operations of the Company.

    In 1990, the Division of Enforcement of the Securities and Exchange
    Commission (the "SEC") began conducting an informal inquiry regarding
    various Company production programs, program and contract estimates at
    completion and related accounting practices.  Following the filing of a
    registration statement with the SEC, the Company received on August 17,
    1993, and shortly thereafter responded to, a request for documents from the
    SEC Division of Enforcement concerning its decision to change its accounting
    practices relating to long-term programs and contracts, and its previous
    practice of capitalizing pre-certification and certain general and
    administrative costs.  The Company has received no further comments from the
    SEC Division of Enforcement since that date.

    The Company is involved as plaintiff or defendant in various other legal and
    regulatory actions and inquiries incident to its business, none of which are
    believed by management to have a material adverse effect on the financial
    position or results of operations of the Company.

    EMPLOYEE BENEFIT PLANS AND UNUSUAL ITEMS

    The Company reduced the actuarially assumed discount rate for pension plan
    valuation to 7.5% for fiscal year 1994 from the 8.5% used for fiscal year
    1993 in order to reflect prevailing interest rates.  This increased the
    Company's accrued pension benefit obligation.  This change, along with
    increased early retirements and market performance of trust assets,
    increased the reported underfunded status of the plan by $66.6 million to a
    total of $124.1 million as of May 1, 1994.  This $66.6 million increase
    resulted in the recognition of such amount as additional pension liability
    along with a $42 million reduction to shareholders' equity, net of the
    related tax benefits.

    Operating income was reduced by unusual items aggregating $7.9 million,
    representing the write-off of unamortized pension past service costs related
    to the downsizing of employment

                                  Page 7 of 17
<PAGE>
 
    levels in line with current business conditions, net of a gain on the sale
    of the Auburn, Washington facility, which was closed during the prior fiscal
    year.

    SUBSEQUENT EVENTS

    On May 19, 1994, subsequent to the close of the third quarter, the Company
    completed its public offering of $100 million of 11.625% Senior Notes due
    May 15, 2003 and the concurrent public offering of $50 million of 7.75%
    Convertible Subordinated Notes due May 15, 2004. On June 9, 1994, the
    Company was notified that Salomon Brothers Inc, the underwriter for the
    offerings, had elected to exercise its over-allotment option to purchase an
    additional $7.5 million of Convertible Subordinated Notes.

    Approximately $64 million of the net proceeds from these offerings was used
    to repay all amounts outstanding under the Company's revolving credit
    agreement. The remaining proceeds will be used for general corporate
    purposes.

    Both series of notes are general unsecured obligations of the Company paying
    interest semi-annually commencing November, 1994 and do not have sinking
    fund requirements.  The Convertible Subordinated Notes are convertible at
    the option of the holder at any time prior to maturity into shares of the
    Company's common stock at a conversion price of $10.35 per share.

    Effective upon the issue date of the new Notes, the Company amended the
    revolving credit agreement extending the credit commitment through April,
    1997.  The revised commitment is initially for $110 million and steps down
    by $10 million every six months beginning October 1995 until it reaches $80
    million.  This credit facility matures in April 1997.  This amendment, as
    well as amendments to other of the Company's principal financing agreements,
    revised the existing financial covenant levels and removed the requirement
    that the Company issue $100 million of subordinated debt on or prior to
    August 1, 1994.

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

    RESULTS OF OPERATIONS

    Presented below is management's analysis of operating results for the three
    month and nine month periods ended May 1, 1994 and May 2, 1993.  Also
    presented are material developments in the Company's liquidity and capital
    resources since July 31, 1993.  These discussions should be read in
    conjunction with the financial statements and management's discussion and
    analysis thereof included in the Company's July 31, 1993 Form 10K.

                                  Page 8 of 17

    First Nine Months Fiscal 1994 Compared to First Nine Months Fiscal 1993

    Total sales for the first nine months of fiscal year 1994 were $715.9
    million, down $206.9 million or 22.4% from the first nine months of fiscal
    year 1993.  Commercial sales during the first nine months of fiscal year
    1994 were down compared to the same period of fiscal year 1993 due primarily
    to reductions in deliveries.  Government sales for the comparative period
    declined due primarily to a reduction in the delivery rate on the Titan
    program.  Commercial sales aggregated 87% and government sales 13% of the
    Company's total sales in the first nine months of fiscal year 1994, very
    similar to the prior year.

    Operating income for the first nine months of fiscal year 1994 was $38.3
    million.  Operating income was reduced by unusual items aggregating $7.9
    million, representing the write-off of unamortized pension past service
    costs related to the downsizing of employment levels in line with current
    business conditions, net of a gain on the sale of the Auburn, Washington
    facility, which was closed during the prior fiscal year.  Operating income
    before the unusual items was $46.2 million for the first nine months of
    fiscal year 1994 compared to an operating loss of $14.4 million for the same
    period of fiscal year 1993.  A significant contributor to improved operating
    income was reduced general and administrative expenses which declined $13.0
    million from $33.7 million for the first nine months of fiscal 1993 to $20.7
    million in the first nine months of fiscal 1994.  The decline was primarily
    the result of downsizing and other ongoing cost cutting efforts.  Fiscal
    1994 results  are being adversely impacted by a reduction in sales volume on
    several programs.  Fiscal 1993 results were impacted by losses on tooling
    and design efforts, and cost problems related to certain programs including
    the V2500.  In addition, fiscal 1993 results were negatively impacted by a
    $25.0 million net provision for asset and liability valuations and
    litigation uncertainties.  During and shortly following the third quarter of
    fiscal 1994, several of these litigation uncertainties were settled with the
    U.S. Air Force and U.S. Government at amounts in line with provisions
    previously established.

    Net interest expense was $34.7 million for the first nine months of fiscal
    year 1994 compared to $35.4 million for the same period last year.  While
    total debt has declined, interest rates paid by the Company have increased
    primarily due to the replacement of certain variable rate financings with
    long-term fixed rate financings.

    Net income for the first nine months of fiscal year 1994 was a positive $5.0
    million or 28 cents per share compared to a loss of $30.7 million or $1.72
    per share (before the cumulative effect of the accounting change described
    below) for the same period last year.  The net impact of the unusual items
    described above was to reduce net income for the nine months of fiscal 1994
    by

                                  Page 9 of 17
<PAGE>
 
    $4.8 million or 27 cents per share.  The increase in federal income tax
    rates resulting from the Omnibus Budget Reconciliation Act, implemented in
    August 1993, increased net income by $2.8 million and earnings per share or
    16 cents.  Excluding unusual items and the positive impact of the tax act,
    earnings would have been 39 cents per share for the nine months of fiscal
    1994.

    The first nine months of fiscal year 1993 were also impacted by a loss of
    $223.9 million, net of taxes, or $12.52 per share, due to the cumulative
    effect for the changes in the application of accounting principles through
    July 31, 1992, adopted on a retroactive basis in the third quarter of fiscal
    year 1993.

    Third Quarter of Fiscal 1994 Compared to Third Quarter of Fiscal 1993

    Total sales during the third quarter of fiscal 1994 were $231.1 million
    compared to $296.8 million in the third quarter of the fiscal year 1993.
    Commercial sales during the third quarter of fiscal 1994 were down compared
    to the same period of fiscal 1993 due primarily to reduction in deliveries.
    Government sales for the comparable period declined due primarily to a
    reduction in the delivery rate on the Titan program.  Commercial sales
    aggregated 84% and government sales 16% of the Company's total sales in the
    third quarter of fiscal year 1994.

    Operating income for the third quarter of fiscal 1994, excluding the impact
    of unusual items described in the previous section, was $14.5 million,
    representing an operating margin of 6.3 percent.  Including unusual items of
    $7.9 million, operating income was $6.6 million for the third quarter.
    Operating income was impacted by the factors discussed in the previous
    section.

    Additional Items

    In fiscal 1993, the IRS issued a Revenue Agent's Report challenging the
    Company's adoption in 1984 of the Completed Contract Method of Accounting
    ("CCMA"), the Company's tax deduction for funding liabilities related to a
    Voluntary Employee Benefit Association ("VEBA") and certain other matters.
    During the third quarter of fiscal 1994, the IRS conceded that the Company
    was entitled to use CCMA.  The Company is negotiating a resolution of the
    remaining adjustment issues with the IRS.  The Company believes that the
    resolution of these remaining issues will not have a material adverse effect
    on the Company and its financial position.

    Government (military and space) sales accounted for approximately 13% of the
    Company's total sales for the nine months ended May 1, 1994 and for the
    fiscal year ended July 31, 1993.  The

                                 Page 10 of 17
<PAGE>
 
    Company expects that the percentage of Company revenues attributable to
    government sales will decline in future years.  The production rate for the
    Titan rocket motor casing program, which accounted for 5.9% of revenues in
    fiscal 1993, is expected to decline substantially in response to market
    demand.  In addition, another company's alternative technology casing
    approach may allow it to become a leading competitor in the market for this
    product in the future.  The Company's military sales are primarily
    associated with older programs which are being phased out of production.

    Following the end of the third quarter, the Company reached an agreement
    with International Aero Engines on the V2500 program for Airbus A319, A320,
    A321 aircraft under which the Company will continue to manufacture key
    program components and provide total system support.  Retention of this
    program under mutually agreeable contractual terms was a key objective of
    the Company.

    LIQUIDITY AND CAPITAL RESOURCES

    For the first nine months of fiscal year 1994, net cash provided by
    operating activities totaled $56.0 million compared to $45.5 million during
    the first nine months of fiscal year 1993.  Net cash provided by operations
    for the three months ended May 1, 1994 totaled $11.0 million.  During the
    three months ended May 2, 1993, net cash provided by operating activities
    totaled $81.1 million due to several large receipts for tooling, engineering
    changes and similar non-recurring expenses, as well as the receipt of
    certain amounts that had been deferred pending aircraft certification.  Net
    cash provided by operations is subject to significant variations from period
    to period.

    The Company's total debt at May 1, 1994 aggregated $482.1 million, a
    decrease of $49.5 million from $531.6 million on July 31, 1993.  This
    reduction was primarily the result of a scheduled repayment of the medium
    term note for $35 million in October, 1993 and the annual scheduled
    principal payment of $12.5 million in January, 1994 on its 9.35% Senior
    Notes due 2000.  At May 1, 1994, the Company had $50 million of borrowings
    under its committed revolving credit agreement, the same amount borrowed at
    July 31, 1993.  Total financings, which include balance sheet indebtedness
    and off-balance sheet financings, aggregated $572.6 million at May 1, 1994,
    down $71.3 million from July 31, 1993.  In addition to the decline in debt
    reported on the balance sheet, this decrease reflects a temporary reduction
    to the receivables financing program as discussed below.

                                 Page 11 of 17
<PAGE>
 
    The Company is a party to a $60.0 million accounts receivable facility under
    which it sells receivables from specified customers on an on-going basis.
    Due to the slow down in the aerospace industry, the amount of outstanding
    receivables from these customers has fallen below levels which existed at
    the start of the facility.  As a result, the Company has elected to deposit
    cash collateral from time to time as required to support the facility and
    has withdrawn such cash when it is no longer required to be deposited.  At
    May 1, 1994 the Company had $19.2 million of cash collateral on deposit.

    The Company is also a party to certain equipment leases and has granted the
    lessors a security interest in selected customer receivables to secure $10
    million of obligations.  If the parties who lease this equipment to the
    Company do not assign approximately one-half of their beneficial interests
    in the leased equipment to other parties by January 1995, the equipment
    lessors may require the Company to prepay up to $10 million of its equipment
    lease obligations.

    In order to enhance liquidity and improve its financial flexibility, the
    Company adopted a financing plan with the objective of increasing long-term
    financing and extending the Company's revolving credit agreement.  On May
    19, 1994, subsequent to the close of the third quarter, the Company
    completed its public offering of $100 million of 11.625% Senior Notes due
    May 15, 2003 and the concurrent public offering of $50 million of 7.75%
    Convertible Subordinated Notes due May 15, 2004. On June 9, 1994, the
    Company was notified that Salomon Brothers Inc, the underwriter for the
    offerings, had elected to exercise its over-allotment option to purchase an
    additional $7.5 million of Convertible Subordinated Notes.

    Approximately $64 million of the net proceeds from these offerings was used
    to repay all amounts outstanding under the Company's revolving credit
    agreement. The remaining net proceeds will be used for general corporate
    purposes.

    Both series of notes are general unsecured obligations of the Company paying
    interest semi-annually commencing November, 1994 and do not have sinking
    fund requirements.  The Convertible Subordinated Notes are convertible at
    the option of the holder at any time prior to maturity into shares of the
    Company's common stock at a conversion price of $10.35 per share.

    Effective upon the issue date of the new Notes, the Company amended the
    revolving credit agreement extending the credit commitment through April,
    1997.  The revised commitment is initially for $110 million and steps down
    by $10 million every six months beginning October 1995 until it reaches $80
    million.  This credit facility matures in April 1997.  This amendment, as
    well as amendments to other of the Company's principal financing agreements,
    revised the existing financial covenant levels and removed the requirement
    that the Company issue $100 million of subordinated debt on or prior to
    August 1, 1994.

    During the third quarter, the Company renewed a letter of credit securing
    its obligations to the State of California in connection with its self-
    insured workers' compensation program.  A second letter of credit, which
    supports $16.5 million of industrial development bonds, will expire in July,
    1994.  In connection with this pending expiration, the Company will
    repurchase the bonds from the existing holders and is preparing to re-market
    the bonds to new holders.

    The Company has been negotiating the sale of several non-core assets which
    are not material to its business. In March 1994, the Company completed the
    sale of its Auburn, Washington plant which had been closed in fiscal year
    1993. In addition, on June 13, 1994, subsequent to the end of the fiscal
    quarter, the Company completed the sale of its corporate jet product line.
    The Company is continuing to negotiate the sale of its business for the
    overhaul and repair of nacelle and thrust reverser components. The corporate
    jet product line and the overhaul and repair business generated
    approximately $25 million and $10 million, respectively, of revenues in the
    fiscal year ended July 31, 1993.

    As previously announced, the Company reduced the actuarially assumed
    discount rate used to calculate the accrued benefit obligation for its
    pension plans from 8-1/2% used in the prior year to 7-1/2%.  This reduction
    was made to reflect prevailing interest rates.  This change, along with
    increased early retirements and market performance of trust assets,
    increased the reported underfunded status of the plans by $66.6 million to a
    total of $124.1 million as of May 1, 1994.  This $66.6 million increase
    resulted in the recognition of such amount as additional pension liability
    along with a $42 million reduction to shareholders' equity, net of the
    related tax benefits.

    The Company's net inventory decreased to $385.8 million at May 1, 1994 from
    $439.7 million at July 31, 1993.  Production inventory declined as a result
    of the claims settlement on the U.S. Air Force contracts, a slowdown in
    delivery schedules and the efforts of management to control inventory levels
    through shorter lead and cycle times and just-in-time contracts with
    suppliers.  Excess-over-average inventory declined reflecting the increased
    maturity of newer programs.  These reductions were partially offset by an
    increase in pre-production inventory, primarily in the MD-90, A340, PW4000
    and V2500 programs.  Customer progress payments and advances declined
    primarily as a result of the claims settlement on the U.S. Air Force
    contracts.

    Capital expenditures for property, plant and equipment totaled $3.7 million
    for the first nine months of fiscal year 1994, down from $22.9 million in
    the first nine months of fiscal year 1993.  Capital expenditures in the
    first nine months of fiscal year 1993 were higher due in large part to
    expenditures for new office and manufacturing facilities.  In addition, the
    Company has substantially curtailed its previously planned capital
    expenditures for the balance of fiscal year 1994 in line with other cost
    cutting efforts and anticipates such expenditures will not exceed an average
    of $20 million per year over the subsequent four years.  Given its
    substantial recent 

                                 Page 13 of 17
<PAGE>

    investments, the Company believes that the amount it plans to spend on
    capital expenditures over the next several years will be sufficient to meet
    the Company's production requirements.

    The Company's firm backlog, which includes the sales price of all
    undelivered units covered by customers' orders for which the Company has
    production authorization, was approximately $1.3 billion at May 1, 1994
    compared to $1.4 billion at July 31, 1993.  Approximately $0.2 billion of
    the $1.3 billion backlog is expected to be delivered in the remainder of
    fiscal year 1994.  (Sales during any period include certain sales which were
    not part of backlog at the end of the prior period.)  Customer orders in
    firm backlog are subject to rescheduling and/or termination for customer
    convenience; however, in certain cases the Company is entitled to an
    adjustment in contract amounts.  The Company has an additional $2.6 billion
    in anticipated backlog, which represents the sales price of units which the
    Company expects  that its customers will order under existing contracts and
    the Company will deliver within seven years.

[Name and Address of Purchaser]


Gentlemen:

     The undersigned, Rohr, Inc., (together with its predecessor, Rohr
Industries, Inc. and its successors, the "Company"), a Delaware corporation,
hereby agrees with you as follows:

     1.   AUTHORIZATION OF ISSUE OF NOTES.  Rohr Industries, Inc., predecessor
to the Company, has authorized the issuance of its senior promissory notes (the
"Notes") in the aggregate principal amount of One Hundred Million Dollars
($100,000,000) dated the date of issue thereof, to mature on January 29, 2000,
bearing interest on the unpaid balance thereof from the date thereof until the
principal thereof shall have become due and payable at the rate of nine and
thirty-five one-hundredths percent (9.35%) per annum and on overdue payments at
the rate specified therein, which senior promissory notes have been amended
pursuant to the First Amendment and, as amended, are substantially in the form
of Exhibit A attached hereto.  The term "Notes" as used herein shall include
each such senior promissory note delivered pursuant to any provision of this
Agreement and each such senior promissory note delivered in substitution or
exchange for any other Note pursuant to any such provision.


     2.   PURCHASE AND SALE OF NOTES.  The Company sold to you and, subject to
the terms and conditions herein set forth, you purchased from the Company the
aggregate principal amount of Notes set forth opposite your name in the
Purchaser Schedule attached hereto at one hundred percent (100%) of such
aggregate principal amount.  The Company delivered to you, at the offices of
Hebb & Gitlin, a Professional Corporation, at One State Street, Hartford,
Connecticut, one or more Notes registered in your name, evidencing the aggregate
principal amount of Notes purchased by you and in the denomination or
denominations specified with respect to you in the Purchaser Schedule, against
payment of the purchase price thereof by transfer of immediately available funds
as directed by the Company in writing on the date of closing, February 2, 1990
(the "Closing" or the "Closing Date").  Concurrently with the execution and
delivery of this Agreement, the Company is entered into other Note Agreements
(the "Other Note Agreements") substantially identical with this Agreement
(except as to the identity of the purchaser and the principal amount of Notes to
be purchased) with the other purchasers (the "Other Purchasers") named in the
Purchaser Schedule.  The sale to you and the sales to the Other Purchasers were
separate and several sales.

                                      A-6

     4.   PREPAYMENTS.

     4A.  REQUIRED PREPAYMENTS.  Until the Notes shall be paid in full, the
Company shall apply to the prepayment of the Notes, without premium, the sum of
Twelve Million Five Hundred Thousand Dollars ($12,500,000) on January 29 in each
of the years beginning on January 29, 1993, and ending on January 29, 1999,
inclusive, and such principal amounts of the Notes, together with interest
thereon to the prepayment dates, shall become due on such prepayment dates.  The
remaining Twelve Million Five Hundred Thousand Dollars ($12,500,000) in
principal amount of the Notes, together with interest accrued thereon, shall
become due on the maturity date of the Notes.

     4B.  OPTIONAL PREPAYMENT WITH YIELD-MAINTENANCE PREMIUM.  The Notes shall
be subject to prepayment, in whole at any time or from time to time in part (in
multiples of $5,000,000), at the option of the Company, at one hundred percent
(100%) of the principal amount so prepaid plus interest thereon to the
prepayment date and the Yield-Maintenance Premium, if any, with respect to the
principal amount so prepaid.  Any prepayment made by the Company pursuant to
this paragraph 4B shall be applied first to the principal of the Notes due on
the maturity date thereof and second to the prepayments required by this
paragraph 4 in the inverse order of their scheduled due dates.

     4C.  NOTICE OF OPTIONAL PREPAYMENT.  The Company shall give the holder of
each Note irrevocable written notice of any prepayment to be made pursuant to
paragraph 4 hereof not less than ten (10) Business Days prior to the prepayment
date, specifying such prepayment date and the principal amount of the Notes, and
of the Notes held by such holder, to be prepaid on such date and stating that
such prepayment is to be made pursuant to paragraph 4 hereof.  Notice of
prepayment having been given as aforesaid, the principal amount of the Notes
specified in such notice, together with interest thereon to the prepayment date
and together with the premium, if any, herein provided, shall become due and
payable on such prepayment date.

     4D.  PARTIAL PREPAYMENTS PRO RATA.  Upon any prepayment of the Notes, the
principal amount so prepaid shall be allocated to all Notes at the time
outstanding in proportion to the respective outstanding principal amount thereof
(including, for the purpose of this paragraph only, all Notes prepaid or
otherwise retired or purchased or otherwise acquired by the Company or any
Subsidiary or Affiliate).

     4E.  RIGHT TO PUT.

     (i) GRANTING OF PUT.  The Company hereby gives and grants to each holder of
Notes the option, right and privilege (such option, right and privilege herein
collectively referred to as the "Right to Put") to require the Company, upon or
after the occurrence of any Designated Event, to purchase from such holder on
the terms and conditions hereinafter set forth, and the Company agrees so to
purchase from such holder, for an amount equal to the Agreed Put Consideration,
all, but not less than all, of the Notes held by such holder.

     (ii) EXERCISE OF PUT.  Within ten (10) Business Days after the occurrence
of any Designated Event, the Company shall give each holder of Notes written
notice thereof describing such Designated Event, and the facts and circumstances
surrounding the occurrence thereof, in reasonable detail.  At any time prior to
ninety (90) days after any holder of Notes shall receive

                                      A-8
<PAGE>
 
such notice, such holder may exercise its Right to Put by delivering to the
Company a notice of sale (a "Notice of Sale") substantially in the form of
Exhibit F hereto.  If a holder of Notes shall deliver a Notice of Sale, the
Company shall purchase the Notes then held by such holder on the date specified
in such notice (which shall be not less than fifteen (15) days after delivery of
such Notice of Sale), and such holder shall sell such Notes to the Company
without recourse, representation or warranty (other than as to such holder's
full right, title and interest to such Notes free of any adverse claim therein),
at a price, payable in immediately available funds by wire transfer to the
account specified pursuant to paragraph 11 hereof or to such other account as
may be specified in such notice, equal to the Agreed Put Consideration.  Each
holder of Notes shall have the rights specified in this paragraph 4 with
respect to each Designated Event which shall occur, regardless of any act or
omission to act with respect to any previous Designated Event.

     4F.  RETIREMENT OF NOTES.  The Company shall not, and shall not permit any
of the Subsidiaries or Affiliates to, prepay or otherwise retire in whole or in
part prior to their stated final maturity (other than by prepayment pursuant to
paragraph 4A or paragraph 4B or upon acceleration of such final maturity
pursuant to paragraph 7A), or purchase or otherwise acquire, directly or
indirectly (other than pursuant to paragraph 4E, paragraph 4G or paragraph 5H
hereof), Notes held by any holder unless the Company or such Subsidiary or
Affiliate shall have offered to prepay or otherwise retire or purchase or
otherwise acquire, as the case may be, the same proportion of the aggregate
principal amount of Notes held by each other holder of Notes at the time
outstanding upon the same terms and conditions.  Any Notes so prepaid or
otherwise retired or purchased or otherwise acquired by the Company or any of
the Subsidiaries or Affiliates shall not be deemed to be outstanding for any
purpose under this Agreement except as provided in paragraph 4D hereof.

     4G.  TENDER OF NOTES IN PAYMENT OF WARRANT EXERCISE PRICE.  The Warrant
Agreement will provide that the purchase price for the Warrants issuable
thereunder may be paid, in whole or in part, by a tender of Notes.  The Company
shall be deemed to have reacquired a principal amount of Notes equal to the
aggregate principal amount of Notes tendered in payment of the Warrant exercise
price, and such Notes so deemed to have been reacquired shall not be considered
outstanding for any purposes of this Agreement.  In the event that less than the
entire outstanding principal amount of a Note is tendered in payment of the
Warrant exercise price, the Company shall issue and deliver to the holder
thereof a new Note equal in principal amount to the outstanding principal amount
of the Note so tendered less the portion thereof applied to the Warrant exercise
price.

     5.   AFFIRMATIVE COVENANTS.  The Company covenants that on and after the
Closing Date, and so long as any Notes are outstanding, it shall comply with the
following:

     5A.  PAYMENT OF TAXES AND CLAIMS.  The Company will, and will cause each
Subsidiary to, pay before they become delinquent,

          (i)  all taxes, assessments and governmental charges or levies imposed
     upon it or its Property, and

                                      A-9
<PAGE>
 
          (ii)  all claims or demands of materialmen, mechanics, carriers,
     warehousemen, landlords and other like Persons that, if unpaid, will more
     likely than not result in the creation of a Lien upon its Property,

provided that items of the foregoing description need not be paid while being
contested in good faith and in an appropriate manner.

     5B.  MAINTENANCE OF PROPERTIES AND CORPORATE EXISTENCE.  The Company will,
and will cause each Subsidiary to,

          (i) PROPERTY -- maintain its Property in good condition and make all
     necessary renewals, replacements, additions, betterments and improvements
     thereto;

          (ii)  INSURANCE --

               (a)  maintain, with financially sound and reputable insurers,
          insurance (or maintain self-insurance, including without limitation,
          insurance with subsidiaries, if that shall be reasonable in the
          circumstances) with respect to its Property and business against such
          casualties and contingencies, of such types (including, without
          limitation, loss or damage, public liability, business interruption,
          larceny, embezzlement or other criminal misappropriation) and in such
          amounts as is reasonably appropriate for the risks associated with the
          business of the Company and the Subsidiaries; and

               (b) at your request, deliver to you for examination, as soon as
          practicable, policies or certificates of insurance or self-insurance
          or certificates of insurance brokers evidencing compliance with the
          provisions of this clause (ii);

          (iii)  FINANCIAL RECORDS -- keep true books of records and accounts in
     which full and correct entries shall be made of all its business
     transactions so that the financial statements required by paragraph 5D
     hereof may be prepared in accordance with generally accepted accounting
     principles;

          (iv) CORPORATE EXISTENCE AND RIGHTS -- maintain, preserve and renew
     the Company's existence as a corporation organized under the laws of a
     state of the United States of America; and

          (v) COMPLIANCE WITH LAW -- not be in violation of any law, ordinance
     or governmental rule or regulation to which it is subject (including,
     without limitation, laws, ordinances, rules or regulations relating to
     environmental matters) and not fail to obtain any license, permit,
     franchise or other governmental authorization necessary to the ownership of
     its Properties or to the conduct of its business, which violation or
     failure to obtain will, more likely than not, materially adversely affect
     the business or financial condition of the Company and the Subsidiaries,
     taken as a whole, or the ability of the Company to perform its obligations
     set forth in this Agreement and in the Notes.

                                      A-10
<PAGE>
 
     5C.  PAYMENT OF NOTES AND MAINTENANCE OF OFFICE.  The Company will
punctually pay, or cause to be paid, the principal and interest (and premium, if
any) to become due in respect of the Notes according to the terms thereof and
shall maintain an office at the address of the Company set forth in paragraph
11 hereof where notices, presentations and demands in respect of this Agreement
or the Notes may be made upon it.  Such office shall be maintained at such
address until such time as the Company shall notify the holders of the Notes of
any change of location of such office.

     5D.  FINANCIAL REPORTING AND NOTICES.

     (i) FINANCIAL REPORTING.  The Company will deliver to each holder of Notes
in duplicate:

          (a)  as soon as practicable and in any event within sixty (60) days
     after the end of each quarterly period (other than the last quarterly
     period) in each fiscal year, consolidated statements of income and cash
     flows of the Company and the Subsidiaries for such period and for the
     period from the beginning of the current fiscal year to the end of such
     quarterly period, and a consolidated balance sheet of the Company and the
     Subsidiaries as at the end of such quarterly period, setting forth in each
     case in comparative form figures for the corresponding period in the
     preceding fiscal year, accompanied by additional financial statements
     containing the same information prepared in accordance with generally
     accepted accounting principles as then in effect if the accounting
     principles applied by the Company in the preparation of the financial
     statements first described in this clause (a) differ in any material
     respect from generally accepted accounting principles as then in effect, in
     both cases in reasonable detail and certified by an authorized financial
     officer of the Company, subject to changes resulting from year-end
     adjustments; provided, however, that so long as the accounting principles
     applied by the Company in the preparation of the financial statements first
     described in this clause (a) do not differ in any material respect from
     generally accepted accounting principles as then in effect, delivery
     pursuant to clause (c) below of copies of the Quarterly Report on Form 10-Q
     of the Company for such quarterly period filed with the Securities and
     Exchange Commission shall be deemed to satisfy the requirements of this
     clause (a) (provided that such Form 10-Q is accompanied by any other
     financial information incorporated by reference in such Form 10-Q, and
     provided further, that the Company provide to each holder who so requests
     in writing any document incorporated by reference in such Form 10-Q);

          (b)  as soon as practicable and in any event within ninety (90) days
     after the end of each fiscal year, consolidating and consolidated
     statements of income and cash flows of the Company and the Subsidiaries for
     such year, and consolidating and consolidated balance sheets of the Company
     and the Subsidiaries as at the end of such year, setting forth in each case
     in comparative form corresponding figures from the preceding annual audit,
     accompanied by additional financial statements containing the same
     information prepared in accordance with generally accepted accounting
     principles as then in effect if the accounting principles applied by the
     Company in the preparation of the financial statement first described in
     this clause (b) differ in any material respect from generally accepted
     accounting principles as then in effect, in both cases all in reasonable
     detail and satisfactory in scope to the Required Holders and, as to the
     consolidated statements

                                      A-11
<PAGE>
 
     prepared under generally accepted accounting principles as then in effect,
     certified to the Company by independent public accountants of recognized
     standing selected by the Company whose certificate shall be in scope and
     substance satisfactory to the Required Holders in their reasonable
     judgment, and, as to the consolidating statements and financial statements
     not certified by such independent public accountants, certified by an
     authorized financial officer of the Company; provided, however, that so
     long as the accounting principles applied by the Company in the preparation
     of the financial statements first described in this clause (b) do not
     differ in any material respect from generally accepted accounting
     principles as then in effect, delivery pursuant to clause (c) below of
     copies of the Annual Report on Form 10-K of the Company for such fiscal
     year filed with the Securities and Exchange Commission shall be deemed to
     satisfy the requirements of this clause (b) (provided that such Form 10-K
     is accompanied by any other financial information incorporated by reference
     in such Form 10-K, and provided further, that the Company provide to each
     holder who so requests in writing any document incorporated by reference in
     such Form 10-K);

          (c)  promptly upon transmission thereof, copies of all such financial
     statements, proxy statements, notices and reports that it sends to its
     public stockholders and copies of all registration statements (without
     exhibits) and all reports that it files with the Securities and Exchange
     Commission (or any governmental body or agency succeeding to the functions
     of the Securities and Exchange Commission); and

          (d)  copies of all agreements governing and instruments evidencing
     Debt (other than Debt of a type described in subsection (vi) of the
     definition of Debt) of the Company or any Consolidated Subsidiary
     containing any Financial Covenant, and all agreements amending, modifying
     or supplementing any such agreement or instrument affecting, adding or
     deleting any Financial Covenant, in each case, entered into on or after the
     First Amendment Date;

          (e) all certificates and notices delivered or required to be delivered
     to the holders of any other Debt of the Company or any Consolidated
     Subsidiary on or after the First Amendment Date, in each case, in
     connection with the compliance by the Company or any Consolidated
     Subsidiary with any Financial Covenant; and

          (f) with reasonable promptness, such other financial data as such
     holder of Notes may reasonably request.

     (ii) DEFAULT NOTICES.  The Company also covenants that immediately upon any
Senior Officer of the Company obtaining knowledge of an Event of Default or
Default, it will deliver to each holder of Notes an Officer's Certificate
specifying the nature and period of existence thereof and what action the
Company proposes to take with respect thereto.

     5E.  INSPECTION OF PROPERTY.  The Company will permit any Person designated
in writing by any holder of Notes, at such holder's expense, to visit and
inspect any of the Properties of the Company and the Subsidiaries, to examine
the corporate books and financial records of the Company and the Subsidiaries
and make copies thereof or extracts therefrom, all at such reasonable times and
as often as such holder may reasonably request.  In addition, so long as (i) a
Default or an Event of Default shall have occurred and be continuing, (ii) in
the

                                      A-12
<PAGE>
 
reasonable judgment of any holder of Notes, a material adverse change shall have
occurred with respect to the business or financial condition of the Company and
the Subsidiaries taken as a whole, or (iii) any holder shall have a reasonable
basis for questioning the validity of any line item in any financial statement
of the Company or the validity of such financial statement as a whole, the
Company will permit any Person designated in writing by any holder to discuss
the affairs, finances and accounts of any of such corporations with the
principal officers of the Company and its independent public accountants, all at
such reasonable times and as often as such holder may reasonably request.

     5F.  COVENANT TO SECURE NOTE EQUALLY.  The Company covenants that, if it or
any Subsidiary shall create or assume any Lien upon any of its Property, whether
now owned or hereafter acquired, other than Liens permitted by the provisions of
paragraph 6A hereof or any similar provision incorporated herein by reference
(unless prior written consent to the creation or assumption thereof shall have
been obtained pursuant to paragraph 11C hereof), it will make or cause to be
made effective provision whereby the Notes will be secured by such Lien equally
and ratably with any and all other Debt thereby secured so long as any such
other Debt shall be so secured.

     5G.  ERISA COMPLIANCE.  Neither the Company nor any Subsidiary will cause
any Plan maintained or participated in by it to engage in any "prohibited
transaction," as such term is defined in Section 4975 of the IRC.

     5H.  INVOLUNTARY PREPAYMENT.

          (i) Upon the occurrence of any Prepayment Event, the Company shall
     make an offer to the holders of Notes to repurchase the Notes as set forth
     in this paragraph 5H.  Immediately upon the occurrence of the Prepayment
     Event but in any event within five (5) Business Days thereafter, the
     Company shall give each holder of the Notes substantially simultaneous
     written notice thereof describing such Prepayment Event in reasonable
     detail including, without limitation, a description of the issue of Debt
     giving rise to such Prepayment Event, the facts and circumstances
     surrounding the occurrence thereof, the manner of the prepayment,
     redemption  or defeasance of such other Debt in connection therewith and
     the manner specified in this paragraph 5H of accepting or rejecting such
     offer by the holder.  Such notice shall also contain the Company's offer
     (the "Prepayment Offer") to purchase from each such holder of Notes a
     principal amount of the Notes held by such holder equal to its Noteholder
     Share of the Ratable Prepayment Amount at a purchase price equal to the
     Agreed Put Consideration.

          (ii) A holder of Notes may accept the Prepayment Offer, in whole or in
     part, through a written acceptance (the "Noteholder Acceptance") delivered
     to the Company within forty-five (45) days of such holder's receipt of the
     Prepayment Offer (the "Offer Period").  Promptly after (and, in any event,
     within two (2) Business Days of) its receipt of any Noteholder Acceptance,
     the Company shall give substantially simultaneous written notice thereof to
     all other holders of Notes.

          (iii)  If such holder shall accept the offer, the Company shall
     purchase that portion (the "Prepayment Portion"), expressed as a
     percentage, of the principal amount of Notes held by such holder specified
     in its Noteholder Acceptance, provided that the

                                      A-13
<PAGE>
 
     principal amount of Notes the Company is required to purchase shall not
     exceed such holder's Noteholder Share of the Ratable Prepayment Amount.
     Such purchase shall be made on the fifteenth (15th) day after the
     expiration of the Offer Period or, if later, the first day on which any
     holder of any other issue of Debt would receive a prepayment in respect of
     such Prepayment Event but in no event later than sixty (60) days after the
     expiration of the Offer Period.  On the date of purchase, such holder shall
     sell the Prepayment Portion of such Notes to the Company without recourse,
     representation or warranty (other than as to such holder's full right,
     title and interest to the Prepayment Portion of such Notes free of any
     adverse claim created by such holder therein), at a price, payable in
     immediately available funds by wire transfer to the account specified
     pursuant to paragraph 11 hereof or to such other account as may be
     specified in such notice, equal to the Agreed Put Consideration.

          (iv) Upon any partial prepayment of a Note pursuant to this paragraph
     5H, such Note may, at the option of the holder thereof, be:

               (a) surrendered to the Company, in which case the Company shall
          promptly execute and issue to the holder thereof a new Note in a
          principal amount equal to the principal amount remaining unpaid on the
          surrendered Note after giving effect to such prepayment; or

               (b) made available to the Company for notation thereon of the
          portion of the principal so prepaid.

     In case the entire principal amount of any Note is prepaid, such Note shall
     be surrendered to the Company for cancellation and shall not be reissued,
     and no Note shall be issued in lieu of the prepaid principal amount of any
     Note.

          (v) If the occurrence of any Prepayment Event causes the Company or
     any Subsidiary to defease, repay, repurchase or have a reduction in the
     available commitment under any issue of Debt prior to the time that any
     Notes would be repurchased hereunder, then simultaneously with such
     defeasance, repayment, repurchase or reduction in respect of such other
     Debt, the Company shall pay to each holder an amount equal to its
     Noteholder Share of the Ratable Prepayment Amount at a purchase price equal
     to the Agreed Put Consideration, which payment shall satisfy all
     obligations of the Company to the holders in respect of clauses (i) through
     (iii), inclusive, of this paragraph 5H.  At the time of the making of such
     payment, the Company shall notify the holder of such payment in writing,
     which notice shall state that such payment is being made pursuant to this
     paragraph 5H(v), shall contain a description of the issue of Debt giving
     rise to such Prepayment Event, the facts and circumstances surrounding the
     occurrence thereof and the manner of the prepayment, redemption or
     defeasance of such other Debt in connection therewith (unless such
     information shall have been contained in a previously delivered notice
     pursuant to paragraph 5H(i) with respect to such Prepayment Event) and
     describe the procedure detailed in this paragraph 5H(v) pursuant to which a
     holder may elect to rescind such payment.

          In the event that a holder of Notes receiving a payment pursuant to
     this paragraph 5H(v) elects to rescind the prepayment arising from such
     Prepayment Event

                                      A-14
<PAGE>
 
     with respect to all Notes or any portion of the Notes held by such holder,
     such holder shall deliver to the Company, within forty-five (45) days of
     such holder's receipt of the notice specified in this paragraph 5H(v),
     written notice of such recision, and shall contemporaneously pay to the
     Company in immediately available funds an amount equal to the amount so
     paid such holder pursuant to this paragraph 5H(v) or, in the case of a
     recision with respect to only a portion of the prepayment made to such
     holder, an amount equal to that portion of such prepayment which such
     holder wishes to rescind.

          (vi) Each holder of Notes shall have the rights specified in this
     paragraph 5H with respect to each Prepayment Event which shall occur,
     regardless of any act or omission to act with respect to any previous
     Prepayment Event.  In the event that the Prepayment Event is also a
     Designated Event subject to paragraph 4 of this Agreement, the Company
     shall comply with the provisions of clause (v) of this paragraph 5H with
     respect to the matters contained therein; in all other respect such
     Designated Event will be treated as a Designated Event and not as a
     Prepayment Event, and the Company will be required to comply with paragraph
     4E in connection therewith.  In the event that the Prepayment Event would
     also be an event which results in an Event of Default, this paragraph 5H
     shall not be deemed to in any respects limit the rights and remedies of the
     holders under paragraph 7.

          (vii)  Prepayments made pursuant to this paragraph 5H shall be applied
     ratably to the obligations of the Company to make required prepayments in
     respect of the Notes pursuant to paragraph 4A hereof and to pay the
     remaining principal amount thereof at maturity.

     6.   NEGATIVE COVENANTS.  The Company covenants that on and after the
Closing Date, and so long as any Notes are outstanding, it shall comply with the
following:

     6A.  LIMITATIONS ON LIENS.

          (i) NEGATIVE PLEDGE.  The Company will not, and will not permit any
     Subsidiary to, create, assume, or suffer to exist any Lien upon any of the
     Property of the Company or any Subsidiary, whether now owned or hereafter
     acquired, except:

               (a) Liens securing Debt and other obligations in an aggregate
          principal amount at any time not exceeding ten percent (10%) of
          Consolidated Tangible Net Worth at such time, provided, however, that
          neither the Company nor any Subsidiary shall create, assume or
          otherwise incur any Lien upon any of its respective Properties unless
          the Company is in compliance with paragraph 6R of this Agreement;

               (b) Liens arising out of transactions contemplated by the terms
          of the Trade Receivables Agreement;

               (c) Purchase Money Mortgages if, after giving effect thereto and
          to any concurrent transactions:

                                      A-15
<PAGE>
 
                    (I) each such Purchase Money Mortgage secures an amount not
               exceeding one hundred percent (100%) of the cost of the
               particular Property to which it relates (or, in the case of a
               Lien existing on any Property of any corporation at the time it
               becomes a Subsidiary, the Fair Market Value of such Property at
               such time);

                    (II) such Purchase Money Mortgage encumbers only Property
               (A) purchased after the Closing Date and (B) acquired with the
               proceeds of the Debt secured thereby; and

                    (III)  such Property was acquired in the ordinary course of
               business of the corporation acquiring such Property,

          provided, however, that neither the Company nor any Subsidiary shall
          create, assume or otherwise incur any Purchase Money Mortgage unless
          the Company is in compliance with paragraph 6R of this Agreement;

               (d) Liens incurred in connection with Lease Transactions to the
          extent that such Liens encumber Property covered by such Lease
          Transactions; provided, however, that neither the Company nor any
          Subsidiary shall create, assume or otherwise incur any such Liens
          unless the Company is in compliance with paragraph 6R of this
          Agreement, and provided further that, immediately after giving effect
          to the investment of the Company or the Subsidiary in such Lease
          Transaction, the aggregate amount of the investments then outstanding
          of the Company and the Subsidiaries in all Lease Transactions does not
          exceed Fifty Million Dollars ($50,000,000), it being agreed that for
          the purpose of such calculation the amount of each investment shall be
          determined on a Net After-Tax Cash Basis;

               (e) Liens upon San Marcos Bonds, and the proceeds thereof, which
          have been repurchased upon tender by the holders thereof in accordance
          with the terms of the indenture governing such San Marcos Bonds,
          until, but only until, the trustee with respect to such San Marcos
          Bonds has received the purchase price therefor upon the remarketing
          thereof and the issuer of the letter of credit that was drawn in
          connection with such tender has been reimbursed for such amounts
          drawn; provided, however, that the Company shall actively seek to
          remarket such bonds pursuant to the provisions of the IDB Financing of
          the Company's San Marcos, Texas facility or, to the extent necessary
          in connection with any termination of any outstanding letter of credit
          relating to such facility, to modify the structure of such IDB
          Financing to the extent necessary to permit a long-term reissuance of
          the repurchased San Marcos Bonds; and

               (f) unless, at the time of incurrence thereof, a Default or an
          Event of Default shall occur or be continuing, Liens incurred in
          connection with the deposit of cash collateral to secure reimbursement
          obligations of the Company relating to the San Marcos Bonds, but only
          in connection with the extension of an outstanding letter of credit
          relating to such facility and only in an amount of cash collateral not
          exceeding the maximum amount which may be drawn under such

                                      A-16
<PAGE>
 
          letter of credit; provided, however, that the Company shall actively
          seek to obtain a replacement letter of credit that does not require
          cash collateralization (and thus relieves the Company of any
          requirement to deposit cash collateral or to secure such reimbursement
          obligations);

     it being understood that each such Lien may be allocated by the Company to
     any one of the preceding categories in which it may, by the terms of such
     category, be included.

          (ii) FINANCING STATEMENTS.  The Company will not, and will not permit
     any Subsidiary to, sign or file a financing statement under the Uniform
     Commercial Code of any jurisdiction that names the Company or such
     Subsidiary as debtor, or sign any security agreement authorizing any
     secured party thereunder to file any such financing statement, except, in
     any such case, a financing statement filed or to be filed to perfect or
     protect a Lien that the Company or such Subsidiary is entitled to create,
     assume or incur, or permit to exist, under the foregoing provisions of this
     paragraph 6 or to evidence for informational purposes a lessor's interest
     in Property leased to the Company or any such Subsidiary.

     6B.  LIMITATIONS ON LEASES.

          (i) LIMITATIONS ON LEASES.  The Company will not, and will not permit
     any Subsidiary to, at any time be or become liable at any time as lessee
     under any lease (other than a lease giving rise to a Capitalized Lease
     Obligation) having an original (or then unexpired) term of one year or more
     if:

               (a) the aggregate Net Rentals payable in any period of twelve
          (12) consecutive calendar months following such time under such lease
          and all other such leases under which the Company or a Subsidiary is
          lessee, minus

               (b) all amounts of a similar nature due from sub-lessees under
          such leases that are reasonably expected to be collected during the
          same period,

     would exceed ten percent (10%) of Consolidated Tangible Net Worth at such
     time.

          (ii) SUBSIDIARY.  Any corporation that becomes a Subsidiary after the
     Closing Date shall be deemed to have become liable as lessee, at the time
     it becomes a Subsidiary, under all leases (under which it is liable as
     lessee) of such corporation existing immediately after it becomes a
     Subsidiary.

     6C.  LIMITATIONS ON INDEBTEDNESS.  The Company will not, and will not
permit any Subsidiary to, create, issue, assume or guarantee any Debt (other
than Intercompany Debt) except that:

          (i)  on or prior to April 26, 1997:

               (a) the Company may incur Debt under the Credit Agreement or an
          Acceptable Replacement Credit Facility;

                                      A-17
<PAGE>
 
               (b) the Company may incur the 1994 Senior Debt and the 1994
          Subordinated Debt;

               (c) the Company and the Subsidiaries may incur unsecured Debt, in
          an aggregate principal amount not to exceed $10,000,000 at any time
          outstanding; provided, however, that no more than $5,000,000 of such
          amount may be Debt of Subsidiaries;

               (d) the Subsidiaries may incur Debt under revolving credit
          facilities so long as the aggregate amount of all such Debt
          outstanding at any time shall not exceed $5,000,000;

               (e) the Company and the Subsidiaries may incur Debt described in
          clause (vi) of the definition of "Debt" contained in paragraph 10B;

               (f) Debt incurred in connection with the resale or remarketing of
          San Marcos Bonds, but only to the extent that:

                    (I) San Marcos Bonds in an aggregate principal amount of
               Sixteen Million Five Hundred Thousand Dollars ($16,500,000) were
               issued and outstanding and held and owned by Persons other than
               the Company, any Subsidiary or any Affiliate on May 10, 1994; and

                    (II) the San Marcos Bonds to be resold or remarketed were
               repurchased by the Company upon tender by the holders thereof
               after May 10, 1994 in accordance with the terms of the indenture
               governing the San Marcos Bonds;

          and

               (g) replacement unsecured San Marcos Bonds, in an aggregate
          principal amount not exceeding Sixteen Million Five Hundred Thousand
          Dollars ($16,500,000), if, and only if, Sixteen Million Five Hundred
          Thousand Dollars ($16,500,000) in aggregate amount of San Marcos Bonds
          were redeemed in full as a result of the failure of the bank which has
          issued any letter of credit relating to the San Marcos Bonds to extend
          or renew such outstanding letter of credit (for the avoidance of
          doubt, the aggregate principal amount of San Marcos Bonds and
          replacement San Marcos Bonds, whether outstanding on the date hereof
          or thereafter issued pursuant to clause (f) or clause (g) of this
          paragraph 6C(i), shall not exceed Sixteen Million Five Hundred
          Thousand Dollars ($16,500,000) at any time);

     in each case, so long as after the incurrence thereof, and after giving
     effect thereto, no Default or Event of Default (including any Default or
     Event of Default arising out of any breach of paragraph 6L hereof) shall
     have occurred or be continuing; and

                                      A-18
<PAGE>
 
          (ii) on or after April 27, 1997, and at any time during any period set
     forth in the tables below, the Company or any Subsidiary may incur Debt if,
     immediately after giving effect to such incurrence of Debt:

               (a) Consolidated Senior Debt would not exceed the percentage
          applicable to such period of the sum of Consolidated Total Debt plus
          Consolidated Tangible Net Worth, all as set forth in the table
          immediately below:

               If such time occurs during the period:    Percentage:

     thereto, no Default or Event of Default (including any Default or Event of
     Default arising out of any breach of paragraph 6L or paragraph 6R hereof)
     shall have occurred or be continuing.

     6D.  LIMITATIONS ON MERGERS AND SALES OF ASSETS.  The Company will not, and
will not permit any Subsidiary to (whether in a single transaction or a series
of transactions), consolidate with, merge into or transfer substantially all of
its Property (whether now owned or hereafter acquired) to any other Person, or
permit any other Person to consolidate with, merge into, or transfer
substantially all of its Property to, the Company, except that any Subsidiary
may merge or consolidate with or into, or transfer substantially all of its
Property to, or acquire substantially all of the Property of, any other Person
and the Company may merge or consolidate with or into, or acquire substantially
all of the Property of, any other Person, if:

          (i) in the case of any merger or consolidation involving the Company,
     the corporation that results from such merger or consolidation is organized
     under the laws of the United States of America or any jurisdiction thereof

     this Agreement to be performed or observed by the Company, all in an
     agreement or instrument satisfactory in form and substance to the Required
     Holders;

          (ii) immediately after the consummation of the transaction, and after
     giving effect thereto, the Company, the corporation that results from any
     such merger or consolidation with the Company or the Person that acquires
     such Property from the Company, and in each case, its Subsidiaries shall be
     engaged principally in the businesses of either or both of manufacturing
     and distributing aerospace products or technically related products and of
     providing services related to such products;

          Dividend if, prior to and immediately after giving effect to such
          Permitted Preferred Dividend, no Default or Event of Default shall
          exist.

     6M.  INCORPORATION OF NEGATIVE COVENANTS.

          (i) During all such times as both the Credit Agreement shall remain in
     force, and either any Debt shall be outstanding thereunder or the lenders
     party thereto shall have any obligation to lend or make advances
     thereunder:

               (a) the provisions of paragraph 6A (except for clauses (i)(e) and
          (i)(f) thereof, to the extent provided in paragraph 6M(i)(c) below)
          and paragraph 6B of this Agreement shall be of no force and effect;

                                      A-22
<PAGE>
 
               (b) the provisions of Sections 5.02(b), 5.02(c), 5.02(d),
          5.02(e), 5.02(g), 5.02(h) and 5.02(i) of the Credit Agreement, as in
          effect on the Third Amendment Date (after giving effect to the Seventh
          Amendment to the Credit Agreement), but without amendment, supplement
          or modification (except as set forth in paragraph 6M(ii) hereof), and
          together with all relevant definitions pertaining thereto, shall be
          incorporated herein by reference, mutatis mutandis;

               (c) the Company shall not, nor shall it permit any Subsidiary to,
          create, assume or suffer to exist any Lien securing any Debt existing
          on the date hereof or incurred thereafter in connection with any IDB
          Financing, except for such Liens as are expressly permitted by the
          provisions of clause (e) or clause (f) of paragraph 6A(i) hereof;

     provided, however, that at all times during which either the Credit
     Agreement shall be of no force or effect, or there shall be no Debt
     outstanding thereunder and no obligation on the part of the lenders thereto
     to lend or make any advance thereunder, the provisions of paragraph 6A and
     paragraph 6B of this Agreement shall be in full force and effect.

          (ii)  If at any time:

               (a) after the Third Amendment Date, the Credit Agreement is
          amended, supplemented or modified to provide Financial Covenants in
          addition to, or which are more restrictive of the Company or the
          Consolidated Subsidiaries than, the provisions of the Credit
          Agreement, as in effect on the Third Amendment Date (after giving
          effect to the Seventh Amendment to the Credit Agreement dated as of
          such date);

               (b) after the First Amendment Date, the Company enters into any
          other agreement governing, or executes any other instrument
          evidencing, any Debt (or any commitment to lend), other than Debt or
          commitments solely among the Company and/or one or more Consolidated
          Subsidiaries; or

               (c) after the First Amendment Date, the Company enters into any
          amendment, supplement or modification of any agreement governing, or
          any instrument evidencing, any Debt (or any commitment to lend), other
          than Debt or commitments solely among the Company and/or one or more
          Consolidated Subsidiaries;

     then, and in each such case, each Financial Covenant set forth in such
     amendment, supplement, modification or other agreement or instrument shall
     be incorporated by reference herein for the remaining term of such
     agreement or instrument, but only to the extent that such covenant is more
     restrictive of the Company or the Consolidated Subsidiaries than the
     corresponding provision of this Agreement.

          (iii)  In the event that any Financial Covenant contained in any other
     agreement governing, or instrument evidencing, any Debt (or commitment to
     lend), which Financial Covenant has been or is incorporated into this
     Agreement pursuant to the provisions of paragraph 6M(ii) hereof, is
     amended, supplemented or modified to make such Financial

                                      A-23
<PAGE>
 
     Covenant less restrictive of the Company or the Consolidated Subsidiaries
     than the incorporated Financial Covenant, the more restrictive incorporated
     Financial Covenant shall continue to be incorporated herein for the
     remaining term of such agreement or instrument notwithstanding such
     amendment, supplement or modification.  Notwithstanding the foregoing
     sentence, if the provisions of such incorporated Financial Covenant were
     expressed when incorporated to be more restrictive on a temporary basis, or
     more restrictive only for a prescribed period, such more restrictive
     provision shall be incorporated herein only on such temporary basis or only
     for such prescribed period, as the case may be.

          (iv) No Financial Covenant incorporated herein by virtue of paragraph
     6M(ii) or paragraph 6M(iii) hereof shall supersede, replace, amend,
     supplement or modify any other provision of this Agreement, including any
     covenant contained herein which addresses a subject matter similar to that
     of such incorporated Financial Covenant.

     6N.  MAINTENANCE OF SENIOR STATUS.  The Company will not take any action at
any time to amend, modify or supplement any subordination provision (or any
definition of any defined term as used in any such provision) in the Existing
Subordinated Notes, the 1994 Subordinated Notes or any indenture governing the
provisions of any thereof, or otherwise take any action which would result in
any of the Existing Subordinated Notes or 1994 Subordinated Notes not being
junior or subordinated in right of payment to the Notes to the same extent such
Existing Subordinated Notes or 1994 Subordinated Notes, as the case may be, are
subordinated to the Notes on the Third Amendment Date (after giving effect to
the issuance of the 1994 Subordinated Notes).  The Company shall not take any
action which would result in the Notes not constituting, or not being fully
entitled to the benefits of, "Senior Indebtedness" and "Designated Senior
Indebtedness" as defined in the indenture governing the 1994 Subordinated Notes.

     6O.  CERTAIN AMENDMENTS.   The Company shall not, nor shall it permit any
Consolidated Subsidiary to, consent to any amendment, modification, supplement
or waiver of:

          (i) any of the provisions of any of Sections 3.02, 3.03, 3.04 or 3.05
     of the Credit Agreement, as in effect on the Third Amendment Date (after
     giving effect to the Seventh Amendment to the Credit Agreement), or any
     other provision referred to therein or any defined term as used therein,
     other than a waiver by the banks party thereto of any condition set forth
     therein; or

          (ii) any other provision of the Credit Agreement or, prior to April
     25, 1997, any Acceptable Replacement Credit Facility, to the extent that
     such amendment, modification, supplement or waiver would have the effect
     of:

               (a) reducing the amount or availability of credit thereunder,
          changing the timing of or reducing the commitments of the lenders
          thereunder to lend or make credits available pursuant thereto;

               (b) making more restrictive upon the Company any condition
          precedent to the funding of the credits available thereunder;

                                      A-24
<PAGE>
 
               (c) requiring the Company or any Subsidiary to grant any lender
          thereunder any Lien securing the obligations thereunder; or

               (d)  requiring the Company or any Subsidiary to maintain any
          deposit accounts in any minimum amount, compensating balances, cash
          management or clearing house relationship or similar arrangements,
          with the lenders thereunder;

in each case, without the prior written consent of the Required Holders.

     6P.  SALES OF ASSETS.  The Company will not, and will not permit any

lease, transfer or otherwise dispose of any Property (except for sales of
inventory and of obsolete or surplus Property in the ordinary course of
business, sales of accounts receivable, the issuance of director's qualifying
shares and sales, leases, transfers or other dispositions of Property to the
Company or a Consolidated Subsidiary (collectively, "Excepted Property"));
provided, however, that the foregoing restrictions shall not apply to the sale,
lease, transfer or other disposition of any such Property to any Person if all
of the following conditions are met:

          (i) the book value of all such Property then being sold, leased,
     transferred or otherwise disposed of, together with the book value of all
     other Property (other than Excepted Property) sold, leased, transferred or
     otherwise disposed of by the Company and the Consolidated Subsidiaries
     since the First Amendment Date shall not, in the aggregate, exceed ten
     percent (10%) of Consolidated Tangible Assets, determined as of the end of
     the then most recently ended fiscal quarter of the Company;

          (ii) in the case of the sale, lease, transfer or other disposition of
     a Consolidated Subsidiary (whether by disposition of any capital stock of
     such Consolidated Subsidiary, the Property thereof or otherwise) or a line
     or segment of business of the Company or a Consolidated Subsidiary, in
     either case, substantially as an entirety (except with respect to the sale,
     lease, transfer or other disposition of capital stock of a Consolidated
     Subsidiary), the sum of:

               (A) that portion, expressed as a percentage, of Gross Operating
          Income attributable to or contributed by all Property of a type
          described in this paragraph 6P(ii) and then being sold, leased,
          transferred or otherwise disposed of, for the period of eight (8) full
          consecutive fiscal quarters most recently ended on or prior to the
          date of such sale, lease, transfer or other disposition; plus

               (B) with respect to each other sale, lease, transfer or other
          disposition of Property of a type described in this paragraph 6P(ii)
          occurring during the period beginning on the later of the First
          Amendment Date and the beginning of the eight full (8) fiscal quarters
          of the Company most recently ended prior to the consummation of the
          transaction referred to in clause (A) above, and ending on the date of
          the transaction referred to in clause (A) above, that portion,
          expressed as a percentage, of Gross Operating Income attributable to
          or contributed by such Property described in this clause (B) for the
          period of eight (8) full consecutive fiscal quarters most recently
          ended on or prior to the date of such sale, lease, transfer or other
          disposition thereof;

                                      A-25
<PAGE>
 
     shall not exceed ten percent (10%);

          (iii)  in the good faith opinion of the board of directors of the
     Company (or a committee of such board to whom such matter has been properly
     delegated), the sale, lease, transfer or other disposition is for Fair
     Market Value and is in the best interests of the Company; and

          (iv) immediately after the consummation of such sale, lease, transfer
     or other disposition, and after giving effect thereto, no Default or Event
     of Default would exist.

Sales and other dispositions of accounts receivable shall be subject to
paragraph 6Q of this Agreement.  Sales of all or any portion of the capital
stock of a Consolidated Subsidiary shall, for purposes of determining the book
value thereof in clause (i) above, be deemed to be the sale of all or such
portion of the book value of the assets of the Consolidated Subsidiary which
shall have issued such capital stock.  Sales of all or a portion of the capital
stock of any Consolidated Subsidiary shall, for purposes of determining its
contribution to Gross Operating Income in clause (ii) above, be deemed to have
contributed all or such portion of that proportion of Gross Operating Income
attributable to the Consolidated Subsidiary which shall have issued such capital
stock.  As used in this paragraph 6P, the term `lease' shall mean an original
lease, as lessor, by the Company or any Consolidated Subsidiary, and the
continuance, extension or renewal of any existing lease shall not be treated as
a lease pursuant to, or restricted by, this paragraph 6P.

     6Q.  SALE OF RECEIVABLES.  The Company covenants that it will not, and will
not permit any Consolidated Subsidiary to, sell with recourse or otherwise sell
for less than the face value thereof, any of its notes or accounts receivable,
except pursuant to the Trade Receivables Agreement; provided, however, that the
Company and any Consolidated Subsidiary may sell for book value the accounts
receivable owing from any Person (i) that has commenced a voluntary case under
the Bankruptcy Law of the United States or any proceedings under the Bankruptcy
Law of any other jurisdiction, or (ii) against whom any such case or proceedings
have been commenced and have remained undismissed for a period of at least sixty
(60) days.

     6R.  LIMITATION ON CERTAIN OBLIGATIONS.  The Company will not at any time
permit the sum of (w) obligations secured by Liens allocated by the Company to

Worth at such time.

     7.   EVENTS OF DEFAULT.

     7A.  ACCELERATION.  If any of the following events shall occur and be
continuing for any reason whatsoever (and whether such occurrence shall be
voluntary or involuntary or come about or be effected by operation of law or
otherwise):

                                      A-26
<PAGE>
 
          (i)  the Company defaults in the payment of any principal of or
     premium on any Note when the same shall become due, either by the terms
     thereof or otherwise as herein provided; or

          (ii)  the Company defaults in the payment of any interest on any Note
     for more than ten (10) days after the date due; or

          (iii)  the Company or any Subsidiary defaults in any payment of
     principal of or interest on any obligation for money borrowed (or any
     Capitalized Lease Obligation, any obligation under a conditional sale or
     other title retention agreement, any obligation issued or assumed as full
     or partial payment for Property whether or not secured by a Purchase Money
     Mortgage or any obligation under notes payable or drafts accepted
     representing extensions of credit) beyond any period of grace provided with
     respect thereto, or the Company or any Subsidiary fails to perform or
     observe any other agreement, term or condition contained in any agreement
     under which any such obligation is created (or if any other event
     thereunder or under any such agreement shall occur and be continuing) and
     the effect of such failure or other event is to cause, or to permit the
     holder or holders of such obligation (or a trustee on behalf of such holder
     or holders) to cause, such obligation to become due prior to any originally
     stated maturity, or to be repurchased by the Company or any Subsidiary,
     provided that the aggregate amount of all obligations as to which such a
     payment default shall occur and be continuing or such a failure or other
     event causing or permitting acceleration shall occur and be continuing
     exceeds Fifteen Million Dollars ($15,000,000), and provided, further, that
     obligations for the deferred purchase price of goods or services
     (including, without limitation, Capitalized Lease Obligations and Purchase
     Money Mortgages) shall be excluded from the operation of this clause (iii)
     so long as such obligations are being contested in good faith by
     appropriate proceedings and adequate reserves have been established

such holder the entire principal of and interest accrued on such Notes and the

     any moneys due on or pursuant to the Notes or this Agreement;

          (b)  all arrears of interest upon all the Notes and all other sums
     payable under the Notes and under this Agreement (except any principal of,
     or interest or Yield-Maintenance Premium on, the Notes that shall have

     this paragraph 7.B) shall have been duly paid; and

          (c)  each and every other Default and Event of Default shall have been
     waived pursuant to paragraph 11.C hereof or otherwise made good or cured.

to such holder in respect thereof under applicable law, either by suit in equity
or by action at law, or both, whether for specific performance of any covenant
or other agreement contained in this Agreement or in aid of the exercise of any
power granted in this Agreement.  No remedy conferred in this Agreement upon the
holder of any Note is intended to be exclusive of any other remedy, and each and
every such remedy shall be cumulative and shall be in addition to every other
remedy conferred herein or now or hereafter existing at law or in equity or by
statute or otherwise.

          (iii)  has all necessary licenses, certificates and permits to own and
     operate its Properties and to carry on its business as now conducted and as
     presently proposed to be conducted, except where the failure to have any

     failures, would not be likely to have a material and adverse effect on the
     business or financial condition of the Company and the Subsidiaries, taken
     as a whole, or the ability of the Company to perform its obligations set
     forth in this Agreement and in the Notes, and

          (iv)  has duly qualified or has been duly licensed, and is authorized
     to do business and is in good standing as a foreign corporation, except
     where the failure to be so qualified, licensed and authorized in any

against the Company or any of the Subsidiaries, or any Properties or rights of
the Company or any of the Subsidiaries, by or before any court, arbitrator or
administrative or governmental body that would be more likely than not to have a

perform its obligations set forth in this Agreement and in the Notes.

     8E.  OUTSTANDING DEBT.  Neither the Company nor any of the Subsidiaries has

issuance or sale of the Notes to the provisions of section 5 of the Securities
Act or to the provisions of any securities or Blue Sky law of any applicable
jurisdiction.

     8K.  REGULATION G, ETC.  Neither the Company nor any Subsidiary owns or has
any present intention of acquiring any "margin stock" as defined in Regulation G
(12 CFR Part 207) of the Board of Governors of the Federal Reserve System
("margin stock").  The proceeds of sale of the Notes will be used for general
corporate purposes.  None of such proceeds will be used, directly or indirectly,
for the purpose, whether immediate, incidental or ultimate, of purchasing or
carrying any margin stock or for the purpose of maintaining, reducing or
retiring any indebtedness that was originally incurred to purchase or carry any
stock that is currently a margin stock or for any other purpose that might
constitute this transaction a "purpose credit" within the meaning of such
Regulation G.  Neither the Company nor any agent acting on its behalf has taken

certificate or statement furnished to you by or on behalf of the Company in
connection herewith contains any untrue statement of a material fact or omits to
state a material fact necessary in order to make the statements contained herein

would, in the aggregate with all other such facts, be more likely than not to
have a material and adverse effect on the business or financial condition of the
Company and the Subsidiaries, taken as a whole, or the ability of the Company to
perform its obligations set forth in this Agreement and in the Notes and that
has not been set forth in this Agreement or in the other documents, certificates

effect on the business or financial condition of the Company and the

the Note so exchanged or transferred, so that neither gain nor loss of interest
shall result from any such transfer or exchange.  Upon receipt of written notice
from the holder of any Note of the loss, theft, destruction or mutilation of
such Note and, in the case of any such loss, theft or destruction, upon receipt
of such holder's unsecured indemnity agreement, or in the case of any such
mutilation, upon surrender and cancellation of such Note, the Company will make

used in the preparation of such financial statements hereafter occasioned by the
promulgation of rules and regulations by or required by the Financial Accounting
Standards Board, the Cost Accounting Standards Board or the Securities and
Exchange Commission (or successors thereto or agencies with similar functions)
result in a material change in the accounting principles used to prepare the
financial statements contained in the Company's Annual Reports on Form 10-K or
Quarterly Reports on Form 10-Q, the Company and the holders of Notes agree, upon
notification of such change by the Company to the holders of Notes or by a
holder of Notes to the Company, to enter into negotiations in order to amend
paragraph 6 and the Financial Covenants incorporated by reference herein, as
applicable, so as to equitably reflect such change with the desired result that

     3G.  CLOSING EXPENSES.  The Company shall have paid at the closing the
statement for fees and disbursements of the special counsel for the Purchasers
presented at the closing.

     4.   PREPAYMENTS.  The Notes shall be subject to prepayment with respect to
the required prepayments specified in paragraph 4A hereof, prepayment with
respect to the optional prepayments permitted by paragraph 4B hereof, repurchase
by the Company at the option of each holder as specified in paragraph 4E,
paragraph 4G hereof and paragraph 5I hereof.

     4A.  REQUIRED PREPAYMENTS.  Until the Notes shall be paid in full, the
Company shall apply to the prepayment of the Notes, without premium, the sum of
Eight Million Eight Hundred Fifty Thousand Dollars ($8,850,000) on December 15
in each of the years 1996 to 2001, inclusive, and such principal amounts of the
Notes, together with interest thereon to the prepayment dates, shall become due
on such prepayment dates.  The remaining Eight Million Nine Hundred Thousand
Dollars ($8,900,000) in principal amount of the Notes, together with interest
accrued thereon, shall become due on the maturity date of the Notes.

     4B.  OPTIONAL PREPAYMENT WITH YIELD-MAINTENANCE AMOUNT.  The Notes shall be
subject to prepayment, in whole at any time or from time to time in part (in
multiples of $5,000,000), at the option of the Company, at one hundred percent
(100%) of the principal amount so prepaid plus interest thereon to the
prepayment date and the Yield-Maintenance Amount, if any, with respect to each
Note.  Any partial prepayment of the Notes pursuant to this paragraph 4B shall
be applied in satisfaction of required payments of principal in inverse order of
their scheduled due dates.

     4C.  NOTICE OF OPTIONAL PREPAYMENT.  The Company shall give the holder of
each Note irrevocable written notice of any prepayment pursuant to paragraph 4B
hereof not less than 30, nor more than 60, days prior to the prepayment date,
specifying such prepayment date and the principal amount of the Notes, and of
the Notes held by such holder, to be prepaid on such date and stating that such
prepayment is to be made pursuant to paragraph 4B of this Agreement.  Notice of
prepayment having been given as aforesaid, the principal amount of the Notes
specified in such notice, together with interest thereon to the prepayment date
and together with the Yield-Maintenance Amount, if any, with respect thereto,
shall become due and payable on such prepayment date.  The Company shall, on or
before the day on which it gives written notice of any prepayment pursuant to
paragraph 4B hereof, give telephonic notice of the principal amount of the Notes
to be prepaid and the prepayment date to each Significant Holder which shall
have designated a recipient of such notices in the Purchaser Schedule attached

together with supporting calculations in reasonable detail.

     4D.  PARTIAL PAYMENTS PRO RATA.  Upon any partial prepayment of the Notes
pursuant to paragraph 4A or paragraph 4B of this Agreement, the principal amount
so prepaid shall be allocated to all Notes at the time outstanding (including,
for the purpose of this paragraph 4D only, all Notes prepaid or otherwise
retired or purchased or otherwise acquired by the Company or any of the
Subsidiaries or Affiliates other than by prepayment pursuant to paragraph 4A,
paragraph 4B or paragraph 5I) in proportion to the respective outstanding
principal amounts thereof.

                                      A-8
<PAGE>
 
     4E.  RIGHT TO PUT.

          (I) GRANTING OF PUT.  The Company hereby gives and grants to each
     holder of Notes the option, right and privilege (such option, right and
     privilege herein collectively referred to as the "Right to Put") to require
     the Company, upon or after the occurrence of any Designated Event, to
     purchase from such holder on the terms and conditions hereinafter set
     forth, and the Company agrees so to purchase from such holder, for an
     amount equal to the Agreed Put Consideration, all, but not less than all,
     of the Notes held by such holder.

          (II) EXERCISE OF PUT.  Within ten (10) Business Days after the
     occurrence of any Designated Event, the Company shall give each holder of
     Notes substantially simultaneous written notice thereof describing such
     Designated Event, and the facts and circumstances surrounding the
     occurrence thereof, in reasonable detail.  At any time prior to ninety (90)
     days after any holder of Notes shall receive such notice, such holder may
     exercise its Right to Put by delivering to the Company a notice of sale (a
     "Notice of Sale") substantially in the form of Exhibit E hereto.  If a
     holder of Notes shall deliver a Notice of Sale, the Company shall purchase
     the Notes then held by such holder on the date specified in such notice
     (which shall be not less than fifteen (15) days after delivery of such
     Notice of Sale), and such holder shall sell such Notes to the Company
     without recourse, representation or warranty (other than as to such
     holder's full right, title and interest to such Notes free of any adverse
     claim therein), at a price, payable in immediately available funds by wire
     transfer to the account specified pursuant to paragraph 11A hereof or to
     such other account as may be specified in such notice, equal to the Agreed
     Put Consideration.  Promptly after (and, in any event, within two (2)
     Business Days of) its receipt of any Notice of Sale, the Company shall give
     substantially simultaneous written notice thereof to all other holders of
     Notes.  Each holder of Notes shall have the rights specified in this
     paragraph 4E with respect to each Designated Event which shall occur,
     regardless of any act or omission to act with respect to any previous
     Designated Event.

     4F.  RETIREMENT OF NOTES.  The Company shall not, and shall not permit any
of the Subsidiaries or Affiliates to, prepay or otherwise retire in whole or in
part prior to their stated final maturity (other than by prepayment pursuant to
paragraph 4A or paragraph 4B or upon acceleration of such final maturity
pursuant to paragraph 7A), or purchase or otherwise acquire, directly or
indirectly (other than pursuant to paragraph 4E hereof, paragraph 4G or
paragraph 5I hereof), Notes held by any holder unless the Company or such
Subsidiary or Affiliate shall have offered to prepay or otherwise retire or
purchase or otherwise acquire, as the case may be, the same proportion of the
aggregate principal amount of Notes held by each other holder of Notes at the
time outstanding upon the same terms and conditions.  Any Notes so prepaid or
otherwise retired or purchased or otherwise acquired by the Company or any of
the Subsidiaries or Affiliates shall not be deemed to be outstanding for any
purpose under this Agreement except as provided in paragraph 4D hereof.

     4G.  TENDER OF NOTES IN PAYMENT OF WARRANT EXERCISE PRICE.  The Warrant
Agreement will provide that the purchase price for the Warrants issuable
thereunder may be paid, in whole or in part, by a tender of Notes.  The Company
shall be deemed to have reacquired a principal amount of Notes equal to the
aggregate principal amount of Notes tendered in payment of the

                                      A-9
<PAGE>
 
Warrant exercise price, and such Notes so deemed to have been reacquired shall
not be considered outstanding for any purposes of this Agreement.  In the event
that less than the entire outstanding principal amount of a Note is tendered in
payment of the Warrant exercise price, the Company shall issue and deliver to
the holder thereof a new Note equal in principal amount to the outstanding
principal amount of the Note so tendered less the portion thereof applied to the
Warrant exercise price.

     5.   AFFIRMATIVE COVENANTS.

     5A.  PAYMENT OF TAXES AND CLAIMS.  The Company will, and will cause each
Subsidiary to, pay before they become delinquent,

          (i) all taxes, assessments and governmental charges or levies imposed
     upon it or its Property, and

          (ii) all claims or demands of materialmen, mechanics, carriers,
     warehousemen, landlords and other like Persons that, if unpaid, will more
     likely than not result in the creation of a Lien upon its Property,

provided that items of the foregoing description need not be paid while being
contested in good faith and in an appropriate manner.

     5B.  MAINTENANCE OF PROPERTIES AND CORPORATE EXISTENCE; OTHER MATTERS.  The
Company will, and will cause each Subsidiary to,

          (I) PROPERTY -- maintain its Property in good condition and make all
     necessary renewals, replacements, additions, betterments and improvements
     thereto;

          (II)  INSURANCE --

               (a) maintain, with financially sound and reputable insurers,
          insurance (or maintain self-insurance, including without limitation,
          insurance with subsidiaries, if that shall be reasonable in the
          circumstances) with respect to its Property and business against such
          casualties and contingencies, of such types (including, without
          limitation, loss or damage, public liability, business interruption,
          larceny, embezzlement or other criminal misappropriation) and in such
          amounts as is reasonably appropriate for the risks associated with the
          business of the Company and the Subsidiaries; and

               (b) at the request of any Significant Holder, deliver to such
          Significant Holder for examination, as soon as practicable, policies
          or certificates of insurance or self-insurance or certificates of
          insurance brokers evidencing compliance with the provisions of this
          clause (ii);

          (III)  FINANCIAL RECORDS -- keep true books of records and accounts in
     which full and correct entries shall be made of all its business
     transactions so that the financial statements required by paragraph 5D
     hereof may be prepared in accordance with generally accepted accounting
     principles as in effect at the time of such preparation;

                                     A-10
<PAGE>
 
          (IV) CORPORATE EXISTENCE AND RIGHTS -- maintain, preserve and renew
     the Company's existence as a corporation organized under the laws of a
     state of the United States of America;

          (V) COMPLIANCE WITH LAW -- not be in violation of any law, ordinance
     or governmental rule or regulation to which it is subject (including,
     without limitation, laws, ordinances, rules or regulations relating to
     environmental matters) and not fail to obtain any license, permit,
     franchise or other governmental authorization necessary to the ownership of
     its Properties or to the conduct of its business, which violation or
     failure to obtain will, more likely than not, materially adversely affect
     the business or financial condition of the Company and the Subsidiaries,
     taken as a whole, or the ability of the Company to perform its obligations
     set forth in this Agreement and in the Notes;

          (VI) OFFERING OF NOTES -- take no action (and will allow no agent
     acting on its behalf to take any action) that would subject the issuance or
     sale of the Notes to the provisions of section 5 of the Securities Act or
     to the registration or qualification provisions of any securities or Blue
     Sky law of any applicable jurisdiction; and

          (VII)  USE OF PROCEEDS -- use the proceeds of sale of the Notes to
     repay Debt of the Company, to reduce the amount of receivables sold
     pursuant to the Trade Receivables Agreement and for general corporate
     purposes.  None of such proceeds will be used, directly or indirectly, for
     the purpose, whether immediate, incidental or ultimate, of purchasing or
     carrying any "margin stock" as defined in Regulation G (12 CFR Part 207) of
     the Board of Governors of the Federal Reserve System (herein called "margin
     stock") or for the purpose of maintaining, reducing or retiring any Debt
     which was originally incurred to purchase or carry any stock that is
     currently a margin stock or for any other purpose which might constitute
     this transaction a "purpose credit" within the meaning of such Regulation
     G.  Neither the Company nor any agent acting on its behalf has taken or
     will take any action which might cause this Agreement or the Notes to
     violate Regulation G, Regulation T, Regulation U, Regulation X or any other
     regulation of the Board of Governors of the Federal Reserve System or to
     violate the Exchange Act, in each case as was in effect on the Closing
     Date, as is now in effect or as the same may hereafter be in effect.

     5C.  PAYMENT OF NOTES AND MAINTENANCE OF OFFICE.  The Company will
punctually pay, or cause to be paid, the principal and interest (and Yield-
Maintenance Amount, if any) to become due in respect of the Notes according to
the terms thereof and shall maintain an office at the address of the Company set
forth in paragraph 11K hereof where notices, presentations and demands in
respect of this Agreement or the Notes may be made upon it.  Such office shall
be maintained at such address until such time as the Company shall notify in
writing the holders of the Notes of any change of location of such office.

     5D.  FINANCIAL STATEMENTS.  The Company covenants that it will deliver to
each Significant Holder in quadruplicate:

     after the end of each quarterly period (other than the last quarterly
     period) in each fiscal year, consolidated statements of income and cash
     flows of the Company and the Subsidiaries

                                     A-11
<PAGE>
 
     for such period and for the period from the beginning of the current fiscal
     year to the end of such quarterly period, and a consolidated balance sheet
     of the Company and the Subsidiaries as at the end of such quarterly period,
     setting forth in each case in comparative form figures for the
     corresponding period in the preceding fiscal year, accompanied by
     additional financial statements containing the same information prepared in
     accordance with generally accepted accounting principles as then in effect
     if the accounting principles applied by the Company in the preparation of
     the financial statements first described in this clause (i) differ in any
     material respect from generally accepted accounting principles as then in
     effect, in both cases in reasonable detail and satisfactory in form to the
     Required Holders and certified by an authorized financial officer of the
     Company, subject to changes resulting from year-end adjustments, provided,
     however, that so long as the accounting principles applied by the Company
     in the preparation of the financial statements first described in this
     clause (i) do not differ in any material respect from generally accepted
     accounting principles as then in effect, delivery pursuant to clause (iii)
     below of copies of the Quarterly Report on Form 10-Q of the Company for
     such quarterly period filed with the Securities and Exchange Commission
     shall be deemed to satisfy the requirements of this clause (i) (provided
     that such Form 10-Q is accompanied by any other financial information
     incorporated by reference in such Form 10-Q, and provided further, that the
     Company provide to each holder of Notes who so requests in writing any
     document incorporated by reference in such Form 10-Q);

     corresponding consolidated figures from the preceding annual audit,
     accompanied by additional financial statements containing the same
     information prepared in accordance with generally accepted accounting
     principles as then in effect if the accounting principles applied by the
     Company in the preparation of the financial statement first described in
     this clause (ii) differ in any material respect from generally accepted
     accounting principles as then in effect, in both cases all in reasonable
     detail and satisfactory in form to the Required Holders and, as to the
     consolidated statements prepared in accordance with generally accepted
     accounting principles as then in effect, reported on by independent public
     accountants of recognized national standing selected by the Company whose
     report shall be without limitation as to the scope of the audit and
     satisfactory in form and substance to the Required Holders and, as to the
     consolidating statements and financial statements not certified by such
     independent public accountants, certified by an authorized financial
     officer of the Company, provided, however, that so long as the accounting
     principles applied by the Company in the preparation of the financial
     statements first described in this clause (ii) do not differ in any
     material respect from generally accepted accounting principles as then in
     effect, delivery pursuant to clause (iii) below of copies of the Annual
     Report on Form 10-K of the Company for such fiscal year filed with the
     Securities and Exchange Commission shall be deemed to satisfy the
     requirements of this clause (ii) (provided that such Form 10-K is
     accompanied by any other financial information incorporated by reference in
     such Form 10-K, and provided further, that the Company provide to each
     holder of Notes who so requests in writing any document incorporated by
     reference in such Form 10-K);

                                     A-12
<PAGE>
 
          (iii) promptly upon transmission thereof, copies of all such financial
     statements, proxy statements, notices and reports as it shall send to its
     public stockholders and copies of all registration statements (without
     exhibits) and all reports which it files with the Securities and Exchange
     Commission (or any governmental body or agency succeeding to the functions
     of the Securities and Exchange Commission);

          (iv) a copy of each other report submitted to the Company or any
     Subsidiary by independent accountants in connection with any annual,
     interim or special audit made by them of the books of the Company or any
     Subsidiary (to be provided to each Significant Holder at such time, if any,
     as the contents of or analysis contained within any such report is (or
     becomes likely to be) incorporated into a Form 10-Q or a Form 10-K filing
     to be made by the Company with the Securities and Exchange Commission);

          (v) copies of all agreements governing and instruments evidencing Debt
     (other than Debt of a type described in subsection (vi) of the definition
     of Debt) of the Company or any Consolidated Subsidiary containing any
     Financial Covenant, and all agreements amending, modifying or supplementing
     any such agreement or instrument affecting, adding or deleting any
     Financial Covenant, in each case, entered into on or after the First
     Amendment Date;

          (vi) all certificates and notices delivered or required to be
     delivered to the holders of any other Debt of the Company or any
     Consolidated Subsidiary on or after the First Amendment Date, in each case,
     in connection with the compliance by the Company or any Consolidated
     Subsidiary with any Financial Covenant; and

          (vii)  with reasonable promptness, such other financial data as such
     Significant Holder may reasonably request.

     Together with each delivery of financial statements required by clauses (i)
and (ii) above, the Company will deliver to each Significant Holder an Officer's
Certificate (a) demonstrating (with computations in reasonable detail, where
appropriate) compliance by the Company and the Subsidiaries with the provisions
of paragraph 6A through paragraph 6M hereof and paragraph 5I, (b) demonstrating
a reconciliation in reasonable detail of the differences between financial
statements prepared in accordance with generally accepted accounting principles
as then in effect and any other similar financial statements provided
contemporaneously therewith prepared other than in accordance with generally
accepted accounting principles, (c) stating that there exists no Event of
Default or Default, or, if any Event of Default or Default exists, specifying
the nature and period of existence thereof and what action the Company proposes
to take with respect thereto, and (d) stating whether or not there has been any
material change in the self-insurance requirements of the Company.

     Together with each delivery of financial statements required by clause (ii)
above, the Company will deliver to each Significant Holder a certificate of such
accountants stating that, in making the audit necessary for their report on such
financial statements, they have obtained no knowledge of any Event of Default or
Default, or, if they have obtained knowledge of any Event of Default or Default,
specifying the nature and period of existence thereof.  Such accountants,
however, shall not be liable to anyone by reason of their failure to obtain
knowledge of any Event

                                     A-13
<PAGE>
 
of Default or Default which would not be disclosed in the course of an audit
conducted in accordance with generally accepted auditing standards.

     5E.  DEFAULT NOTICES.  The Company covenants that immediately after any
Responsible Officer obtains knowledge of an Event of Default or Default, it will
deliver to each Significant Holder an Officer's Certificate specifying the
nature and period of existence thereof and what action the Company proposes to
take with respect thereto.

     5F.  INFORMATION REQUIRED BY RULE 144A.  The Company covenants that it
will, upon the request of any Significant Holder, provide such holder, and any
qualified institutional buyer designated by such holder, such financial and
other information as such Significant Holder may reasonably determine to be
necessary in order to permit compliance with the information requirements of
Rule 144A under the Securities Act in connection with the resale of Notes,
except at such times as the Company is subject to the reporting requirements of
sections 13 or 15(d) of the Exchange Act.  For the purpose of this paragraph 5F,
the term "qualified institutional buyer" shall have the meaning specified in
Rule 144A under the Securities Act.

     5G.  INSPECTION OF PROPERTY.  The Company will permit any Person designated
in writing by any Significant Holder, at such Significant Holder's expense (or
if an Event of Default or a Default shall exist, at the expense of the Company),
to visit and inspect any of the Properties of the Company and the Subsidiaries,
to examine the corporate books and financial records of the Company and the
Subsidiaries and make copies thereof or extracts therefrom, all at such
reasonable times and as often as such Significant Holder may reasonably request.
In addition, so long as (i) a Default or an Event of Default shall have occurred
and be continuing, (ii) in the reasonable judgment of any Significant Holder, a
material adverse change shall have occurred with respect to the business or
financial condition of the Company and the Subsidiaries taken as a whole, or
(iii) any Significant Holder shall have a reasonable basis for questioning the
validity of any line item in any financial statement of the Company or the
validity of such financial statement as a whole, the Company will permit any
Person designated in writing by any Significant Holder to discuss the affairs,
finances and accounts of any of such corporations with the principal officers of
the Company and its independent public accountants, all at such reasonable times
and as often as such Significant Holder may reasonably request.

     5H.  COVENANT TO SECURE NOTE EQUALLY.  The Company covenants that, if it or
any Subsidiary shall create or assume any Lien upon any of its Property, whether
now owned or hereafter acquired, other than Liens permitted by the provisions of
paragraph 6A hereof or any similar provision incorporated herein by reference
(unless prior written consent to the creation or assumption thereof shall have
been obtained pursuant to paragraph 11C hereof), it will make or cause to be
made effective provision whereby the Notes will be secured by such Lien equally
and ratably with any and all other Debt thereby secured so long as any such
other Debt shall be so secured.

                                     A-14

     5I.  INVOLUNTARY PREPAYMENT.

          (i) Upon the occurrence of any Prepayment Event, the Company shall
     make an offer to the holders of Notes to repurchase the Notes as set forth
     in this paragraph 5I.  Immediately upon the occurrence of the Prepayment
     Event but in any event within five (5) Business Days thereafter, the
     Company shall give each holder of the Notes substantially simultaneous
     written notice thereof describing such Prepayment Event in reasonable
     detail including, without limitation, a description of the issue of Debt
     giving rise to such Prepayment Event, the facts and circumstances
     surrounding the occurrence thereof, the manner of the prepayment,
     redemption or defeasance of such other Debt in connection therewith and the
     manner specified in this paragraph 5I of accepting or rejecting such offer
     by the holder.  Such notice shall also contain the Company's offer (the
     "Prepayment Offer") to purchase from each such holder of Notes a principal
     amount of the Notes held by such holder equal to its Noteholder Share of
     the Ratable Prepayment Amount at a purchase price equal to the Agreed Put
     Consideration.

          (ii) A holder of Notes may accept the Prepayment Offer, in whole or in
     part, through a written acceptance (the "Noteholder Acceptance") delivered
     to the Company within forty-five (45) days of such holder's receipt of the
     Prepayment Offer (the "Offer Period").  Promptly after (and, in any event,
     within two (2) Business Days of) its receipt of any Noteholder Acceptance,
     the Company shall give substantially simultaneous written notice thereof to
     all other holders of Notes.

          (iii)  If such holder shall accept the offer, the Company shall
     purchase that portion (the "Prepayment Portion"), expressed as a
     percentage, of the principal amount of Notes held by such holder specified
     in its Noteholder Acceptance, provided that the principal amount of Notes
     the Company is required to purchase shall not exceed such holder's
     Noteholder Share of the Ratable Prepayment Amount.  Such purchase shall be
     made on the fifteenth (15th) day after the expiration of the Offer Period
     or, if later, the first day on which any holder of any other issue of Debt
     would receive a prepayment in respect of such Prepayment Event but in no
     event later than sixty (60) days after the expiration of the Offer Period.
     On the date of purchase, such holder shall sell the Prepayment Portion of
     such Notes to the Company without recourse, representation or warranty
     (other than as to such holder's full right, title and interest to the
     Prepayment Portion of such Notes free of any adverse claim created by such
     holder therein), at a price, payable in immediately available funds by wire
     transfer to the account specified pursuant to paragraph 11.A hereof or to
     such other account as may be specified in such notice, equal to the Agreed
     Put Consideration.

          (iv) Upon any partial prepayment of a Note pursuant to this paragraph
     5I, such Note may, at the option of the holder thereof, be:

               (a) surrendered to the Company, in which case the Company shall
          promptly execute and issue to the holder thereof a new Note in a
          principal amount equal to the principal amount remaining unpaid on the
          surrendered Note after giving effect to such prepayment; or

                                     A-15
<PAGE>
 
               (b) made available to the Company for notation thereon of the
          portion of the principal so prepaid.

     In case the entire principal amount of any Note is prepaid, such Note shall
     be surrendered to the Company for cancellation and shall not be reissued,
     and no Note shall be issued in lieu of the prepaid principal amount of any
     Note.

          (v) If the occurrence of any Prepayment Event causes the Company or
     any Subsidiary to defease, prepay, repurchase or have a reduction in the
     available commitment under any issue of Debt prior to the time that any
     Notes would be repurchased hereunder, then simultaneously with such
     defeasance, prepayment, repurchase or reduction in respect of such other
     Debt, the Company shall pay to each holder an amount equal to its
     Noteholder Share of the Ratable Prepayment Amount at a purchase price equal
     to the Agreed Put Consideration, which payment shall satisfy all
     obligations of the Company to the holders in respect of clauses (i) through
     (iii), inclusive, of this paragraph 5I.  At the time of the making of such
     payment, the Company shall notify the holder of such payment in writing,
     which notice shall state that such payment is being made pursuant to this
     paragraph 5I(v), shall contain a description of the issue of Debt giving
     rise to such Prepayment Event, the facts and circumstances surrounding the
     occurrence thereof and the manner of the prepayment, redemption or
     defeasance of such other Debt in connection therewith (unless such
     information shall have been contained in a previously delivered notice
     pursuant to paragraph 5I(i) with respect to such Prepayment Event) and
     describe the procedure detailed in this paragraph 5I(v) pursuant to which a
     holder may elect to rescind such payment.

          In the event that a holder of Notes receiving a payment pursuant to
     this paragraph 5I(v) elects to rescind the prepayment arising from such
     Prepayment Event with respect to all Notes or any portion of the Notes held
     by such holder, such holder shall deliver to the Company, within forty-five
     (45) days of such holder's receipt of the notice specified in this
     paragraph 5I(v), written notice of such recision, and shall
     contemporaneously pay to the Company in immediately available funds an
     amount equal to the amount so paid such holder pursuant to this paragraph
     5I(v) or, in the case of a recision with respect to only a portion of the
     prepayment made to such holder, an amount equal to that portion of such
     prepayment which such holder wishes to rescind.

          (vi) Each holder of Notes shall have the rights specified in this
     paragraph 5I with respect to each Prepayment Event which shall occur,
     regardless of any act or omission to act with respect to any previous
     Prepayment Event.  In the event that the Prepayment Event is also a
     Designated Event subject to paragraph 4 of this Agreement, the Company
     shall comply with the provisions of clause (v) of this paragraph 5I with
     respect to the matters contained therein; in all other respect such
     Designated Event will be treated as a Designated Event and not as a
     Prepayment Event, and the Company will be required to comply with paragraph
     4E in connection therewith.  In the event that the Prepayment Event would
     also be an event which results in an Event of Default, this paragraph 5I
     shall not be deemed to in any respects limit the rights and remedies of the
     holders under paragraph 7.

                                     A-16
<PAGE>
 
          (vii) Prepayments made pursuant to this paragraph 5I shall be applied
     ratably to the obligations of the Company to make required prepayments in
     respect of the Notes pursuant to paragraph 4A hereof and to pay the
     remaining principal amount thereof at maturity.

     6.   NEGATIVE COVENANTS.

     6A.  LIMITATIONS ON LIENS.

          (I) NEGATIVE PLEDGE.  The Company will not, and will not permit any
     Subsidiary to, create, assume, or suffer to exist any Lien upon any of the
     Property of the Company or any Subsidiary, whether now owned or hereafter
     acquired, except:

               (a) Liens securing Debt and other obligations in an aggregate
          principal amount at any time not exceeding ten percent (10%) of
          Consolidated Tangible Net Worth at such time, provided, however, that
          neither the Company nor any Subsidiary shall create, assume or
          otherwise incur any Lien upon any of its respective Properties unless
          the Company is in compliance with paragraph 6L of this Agreement;

               (b) Liens arising out of transactions contemplated by the terms
          of the Trade Receivables Agreement;

               (c) Purchase Money Mortgages if, after giving effect thereto and
          to any concurrent transactions:

                    (I) each such Purchase Money Mortgage secures an amount not
               exceeding one hundred percent (100%) of the cost of the
               particular Property to which it relates (or, in the case of a
               Lien existing on any Property of any corporation at the time it
               becomes a Subsidiary, the Fair Market Value of such Property at
               such time);

                    (II) such Purchase Money Mortgage encumbers only Property
               (A) purchased after the Closing Date and (B) acquired with the
               proceeds of the Debt secured thereby; and

                    (III)  such Property was acquired in the ordinary course of
               business of the corporation acquiring such Property,

          provided, however, that neither the Company nor any Subsidiary shall
          create, assume or otherwise incur any Purchase Money Mortgage unless
          the Company is in compliance with paragraph 6L of this Agreement;

               (d) Liens incurred in connection with Lease Transactions to the
          extent that such Liens encumber Property covered by such Lease
          Transactions; provided, however, that neither the Company nor any
          Subsidiary shall create, assume or otherwise incur any such Liens
          unless the Company is in compliance with paragraph 6L of this
          Agreement, and provided further that, immediately after

                                     A-17
<PAGE>
 
          giving effect to the investment of the Company or the Subsidiary in
          such Lease Transaction, the aggregate amount of the investments then
          outstanding of the Company and the Subsidiaries in all Lease
          Transactions does not exceed Fifty Million Dollars ($50,000,000), it
          being agreed that for the purpose of such calculation the amount of
          each investment shall be determined on a Net After-Tax Cash Basis;

               (e) Liens upon San Marcos Bonds, and the proceeds thereof, which
          have been repurchased upon tender by the holders thereof in accordance
          with the terms of the indenture governing such San Marcos Bonds,
          until, but only until, the trustee with respect to such San Marcos
          Bonds has received the purchase price therefor upon the remarketing
          thereof and the issuer of the letter of credit that was drawn in
          connection with such tender has been reimbursed for such amounts
          drawn; provided, however, that the Company shall actively seek to
          remarket such bonds pursuant to the provisions of the IDB Financing of
          the Company's San Marcos, Texas facility or, to the extent necessary
          in connection with any termination of any outstanding letter of credit
          relating to such facility, to modify the structure of such IDB
          Financing to the extent necessary to permit a long-term reissuance of
          the repurchased San Marcos Bonds; and

               (f) unless, at the time of incurrence thereof, a Default or an
          Event of Default shall occur or be continuing, Liens incurred in
          connection with the deposit of cash collateral to secure reimbursement
          obligations of the Company relating to the San Marcos Bonds, but only
          in connection with the extension of an outstanding letter of credit
          relating to such facility and only in an amount of cash collateral not
          exceeding the maximum amount which may be drawn under such letter of
          credit; provided, however, that the Company shall actively seek to
          obtain a replacement letter of credit that does not require cash
          collateralization (and thus relieves the Company of any requirement to
          deposit cash collateral or to secure such reimbursement obligations);

     it being understood that each such Lien may be allocated by the Company to
     any one of the preceding categories in which it may, by the terms of such
     category, be included.

          (II) FINANCING STATEMENTS.  The Company will not, and will not permit
     any Subsidiary to, sign or file a financing statement under the Uniform
     Commercial Code of any jurisdiction that names the Company or such
     Subsidiary as debtor, or sign any security agreement authorizing any
     secured party thereunder to file any such financing statement, except, in
     any such case, a financing statement filed or to be filed to perfect or
     protect a Lien that the Company or such Subsidiary is entitled to create,
     assume or incur, or permit to exist, under the foregoing provisions of this
     paragraph 6.A or to evidence for informational purposes a lessor's interest
     in Property leased to the Company or any such Subsidiary.

     6B.  LIMITATIONS ON LEASES.

          (I) LIMITATIONS ON LEASES.  The Company will not, and will not permit
     any Subsidiary to, at any time be or become liable at any time as lessee
     under any lease (other than a lease giving rise to a Capitalized Lease
     Obligation) having an original (or then unexpired) term of one year or more
     if:

               (a) the aggregate Net Rentals payable in any period of twelve
          (12) consecutive calendar months following such time under such lease
          and all other such leases under which the Company or a Subsidiary is
          lessee, minus

               (b) all amounts of a similar nature due from sub-lessees under
          such leases that are reasonably expected to be collected during the

     time.

          (II) SUBSIDIARY.  Any corporation that becomes a Subsidiary after the
     Closing Date shall be deemed to have become liable as lessee, at the time
     it becomes a Subsidiary, under all leases (under which it is liable as
     lessee) of such corporation existing immediately after it becomes a
     Subsidiary.

     6C.  LIMITATIONS ON INDEBTEDNESS.  The Company will not, and will not
permit any Subsidiary to, create, issue, assume or guarantee any Debt (other
than Intercompany Debt) except that:

          an aggregate principal amount not to exceed $10,000,000 at any time
          outstanding; provided, however, that no more than $5,000,000 of such
          amount may be Debt of Subsidiaries;

               (d) the Subsidiaries may incur Debt under revolving credit
          facilities so long as the aggregate amount of all such Debt
          outstanding at any time shall not exceed $5,000,000;

               (e) the Company and the Subsidiaries may incur Debt described in

               Sixteen Million Five Hundred Thousand Dollars ($16,500,000) were
               issued and outstanding and held and owned by Persons other than
               the Company, any Subsidiary or any Affiliate on May 10, 1994; and

                    (II) the San Marcos Bonds to be resold or remarketed were

          principal amount not exceeding Sixteen Million Five Hundred Thousand
          Dollars ($16,500,000), if, and only if, Sixteen Million Five Hundred
          Thousand Dollars ($16,500,000) in aggregate amount of San Marcos Bonds
          were redeemed in full as a result of the failure of the bank which has
          issued any letter of credit relating to the San Marcos Bonds to extend
          or renew such outstanding letter of credit (for the avoidance of
          doubt, the aggregate principal amount of San Marcos Bonds and
          replacement San Marcos Bonds, whether outstanding on the date hereof
          or thereafter issued pursuant to clause (f) or clause (g) of this

     in each case, so long as after the incurrence thereof, and after giving
     effect thereto, no Default or Event of Default (including any Default or
     Event of Default arising out of any breach of paragraph 6R hereof) shall
     have occurred or be continuing; and

          (ii) on or after April 27, 1997, and at any time during any period set

               (a) Consolidated Senior Debt would not exceed the percentage
          applicable to such period of the sum of Consolidated Total Debt plus
          Consolidated Tangible Net Worth, all as set forth in the table
          immediately below:

permit any Subsidiary to, sell or transfer any Property to, or purchase or

     6M.  INCORPORATION OF NEGATIVE COVENANTS.

          (i) During all such times as both the Credit Agreement shall remain in
     force, and either any Debt shall be outstanding thereunder or the lenders
     party thereto shall have any obligation to lend or make advances
     thereunder:

               (a) the provisions of paragraph 6A (except for clauses (i)(e) and
          (i)(f) thereof, to the extent provided in paragraph 6M(i)(c) below)
          and paragraph 6B of this Agreement shall be of no force and effect;

               (b) the provisions of Sections 5.02(b), 5.02(c), 5.02(d),
          5.02(e), 5.02(g), 5.02(h) and 5.02(i) of the Credit Agreement, as in
          effect on the Third Amendment Date (after giving effect to the Seventh
          Amendment to the Credit Agreement), but without amendment, supplement
          or modification (except as set forth in paragraph 6M(ii) hereof), and
          together with all relevant definitions pertaining thereto, shall be
          incorporated herein by reference, mutatis mutandis;

               (c) the Company shall not, nor shall it permit any Subsidiary to,
          create, assume or suffer to exist any Lien securing any Debt existing
          on the date hereof or incurred thereafter in connection with any IDB
          Financing, except for such Liens as are expressly permitted by the
          provisions of clause (e) or clause (f) of paragraph 6A(i) hereof;

     provided, however, that at all times during which either the Credit
     Agreement shall be of no force or effect, or there shall be no Debt
     outstanding thereunder and no obligation on the part of the lenders thereto
     to lend or make any advance thereunder, the provisions of paragraph 6A and
     paragraph 6B of this Agreement shall be in full force and effect.

          (ii)  If at any time:

               (a) after the Third Amendment Date, the Credit Agreement is
          amended, supplemented or modified to provide Financial Covenants in
          addition to, or which are more restrictive of the Company or the
          Consolidated Subsidiaries than, the provisions of the Credit
          Agreement, as in effect on the Third Amendment Date

                                     A-24
<PAGE>
 
          (after giving effect to the Seventh Amendment to the Credit Agreement
          dated as of such date);

               (b) after the First Amendment Date, the Company enters into any
          other agreement governing, or executes any other instrument
          evidencing, any Debt (or any commitment to lend), other than Debt or
          commitments solely among the Company and/or one or more Consolidated
          Subsidiaries; or

               (c) after the First Amendment Date, the Company enters into any
          amendment, supplement or modification of any agreement governing, or
          any instrument evidencing, any Debt (or any commitment to lend), other
          than Debt or commitments solely among the Company and/or one or more
          Consolidated Subsidiaries;

     then, and in each such case, each Financial Covenant set forth in such
     amendment, supplement, modification or other agreement or instrument shall
     be incorporated by reference herein for the remaining term of such
     agreement or instrument, but only to the extent that such covenant is more
     restrictive of the Company or the Consolidated Subsidiaries than the
     corresponding provision of this Agreement.

          (iii)  In the event that any Financial Covenant contained in any other
     agreement governing, or instrument evidencing, any Debt (or commitment to
     lend), which Financial Covenant has been or is incorporated into this
     Agreement pursuant to the provisions of paragraph 6M(ii) hereof, is
     amended, supplemented or modified to make such Financial Covenant less
     restrictive of the Company or the Consolidated Subsidiaries than the
     incorporated Financial Covenant, the more restrictive incorporated
     Financial Covenant shall continue to be incorporated herein for the
     remaining term of such agreement or instrument notwithstanding such
     amendment, supplement or modification.  Notwithstanding the foregoing
     sentence, if the provisions of such incorporated Financial Covenant were
     expressed when incorporated to be more restrictive on a temporary basis, or
     more restrictive only for a prescribed period, such more restrictive
     provision shall be incorporated herein only on such temporary basis or only
     for such prescribed period, as the case may be.

          (iv) No Financial Covenant incorporated herein by virtue of paragraph
     6M(ii) or paragraph 6M(iii) hereof shall supersede, replace, amend,
     supplement or modify any other provision of this Agreement, including any
     covenant contained herein which addresses a subject matter similar to that
     of such incorporated Financial Covenant.

     6N.  MAINTENANCE OF SENIOR STATUS.  The Company will not take any action at
any time to amend, modify or supplement any subordination provision (or any
definition of any defined term as used in any such provision) in the Existing
Subordinated Notes, the 1994 Subordinated Notes or any indenture governing the
provisions of any thereof, or otherwise take any action which would result in
any of the Existing Subordinated Notes or 1994 Subordinated Notes not being
junior or subordinated in right of payment to the Notes to the same extent such
Existing Subordinated Notes or 1994 Subordinated Notes, as the case may be, are
subordinated to the Notes on the Third Amendment Date (after giving effect to
the issuance of the 1994 Subordinated Notes).  The Company shall not take any
action which would result in the Notes not constituting,

                                     A-25
<PAGE>
 
or not being fully entitled to the benefits of, "Senior Indebtedness" and
"Designated Senior Indebtedness" as defined in the indenture governing the 1994
Subordinated Notes.

     6O.  CERTAIN AMENDMENTS.  The Company shall not, nor shall it permit any
Consolidated Subsidiary to, consent to any amendment, modification, supplement
or waiver of:

          (i) any of the provisions of any of Sections 3.02, 3.03, 3.04 or 3.05
     of the Credit Agreement, as in effect on the Third Amendment Date (after
     giving effect to the Seventh Amendment to the Credit Agreement), or any
     other provision referred to therein or any defined term as used therein,
     other than a waiver by the banks party thereto of any condition set forth
     therein; or

          (ii) any other provision of the Credit Agreement or, prior to April
     25, 1997, any Acceptable Replacement Credit Facility, to the extent that
     such amendment, modification, supplement or waiver would have the effect
     of:

               (a) reducing the amount or availability of credit thereunder,
          changing the timing of or reducing the commitments of the lenders
          thereunder to lend or make credits available pursuant thereto;

               (b) making more restrictive upon the Company any condition
          precedent to the funding of the credits available thereunder;

               (c) requiring the Company or any Subsidiary to grant any lender
          thereunder any Lien securing the obligations thereunder; or

               (d)  requiring the Company or any Subsidiary to maintain any
          deposit accounts in any minimum amount, compensating balances, cash

of the following conditions are met:

          (i) the book value of all such Property then being sold, leased,
     transferred or otherwise disposed of, together with the book value of all
     other Property (other than Excepted Property) sold, leased, transferred or
     otherwise disposed of by the Company and the Consolidated Subsidiaries
     since the First Amendment Date shall not, in the aggregate, exceed ten
     percent (10%) of Consolidated Tangible Assets, determined as of the end of
     the then most recently ended fiscal quarter of the Company;

                                     A-26
<PAGE>
 
          (ii) in the case of the sale, lease, transfer or other disposition of
     a Consolidated Subsidiary (whether by disposition of any capital stock of
     such Consolidated Subsidiary, the Property thereof or otherwise) or a line
     or segment of business of the Company or a Consolidated Subsidiary, in
     either case, substantially as an entirety (except with respect to the sale,
     lease, transfer or other disposition of capital stock of a Consolidated
     Subsidiary), the sum of:

               (A) that portion, expressed as a percentage, of Gross Operating
          Income attributable to or contributed by all Property of a type

          transferred or otherwise disposed of, for the period of eight (8) full
          consecutive fiscal quarters most recently ended on or prior to the
          date of such sale, lease, transfer or other disposition; plus

               (B) with respect to each other sale, lease, transfer or other
          disposition of Property of a type described in this paragraph 6P(ii)

          Amendment Date and the beginning of the eight full (8) fiscal quarters
          of the Company most recently ended prior to the consummation of the
          transaction referred to in clause (A) above, and ending on the date of
          the transaction referred to in clause (A) above, that portion,
          expressed as a percentage, of Gross Operating Income attributable to
          or contributed by such Property described in this clause (B) for the

          disposition thereof;

     shall not exceed ten percent (10%);

          (iii)  in the good faith opinion of the board of directors of the
     Company (or a committee of such board to whom such matter has been properly
     delegated), the sale, lease, transfer or other disposition is for Fair
     Market Value and is in the best interests of the Company; and

          (iv) immediately after the consummation of such sale, lease, transfer
     or other disposition, and after giving effect thereto, no Default or Event
     of Default would exist.

Sales and other dispositions of accounts receivable shall be subject to
paragraph 6Q of this Agreement.  Sales of all or any portion of the capital
stock of a Consolidated Subsidiary shall, for purposes of determining the book
value thereof in clause (i) above, be deemed to be the sale of all or such
portion of the book value of the assets of the Consolidated Subsidiary which
shall have issued such capital stock.  Sales of all or a portion of the capital
stock of any Consolidated Subsidiary shall, for purposes of determining its
contribution to Gross Operating Income in clause (ii) above, be deemed to have
contributed all or such portion of that proportion of Gross Operating Income
attributable to the Consolidated Subsidiary which shall have issued such capital
stock.  As used in this paragraph 6P, the term `lease' shall mean an original
lease, as lessor, by the Company or any Consolidated Subsidiary, and the
continuance, extension or renewal of any existing lease shall not be treated as
a lease pursuant to, or restricted by, this paragraph 6P.

Company and any Consolidated Subsidiary may sell for book value the accounts
receivable owing from any Person (i) that has commenced a voluntary case under

          (i) the name of each of the Subsidiaries, its jurisdiction of
     incorporation and the percentage of its Voting Stock owned by the Company
     and each other Subsidiary, and

          (ii) the name of each of the Company's joint ventures and the nature
     thereof.

     Each of the Company and the Subsidiaries has good and marketable title to
all of the shares it purports to own of the stock of each Subsidiary, free and
clear in each case of any Lien.  All such shares have been duly issued and are
fully paid and nonassessable.

     8B.  CORPORATE ORGANIZATION AND AUTHORITY.  The Company

          (i) is a corporation duly organized, validly existing and in good
     standing under the laws of its jurisdiction of incorporation,

          (ii) has all requisite legal and corporate power and authority to own
     and operate its Properties and to carry on its business as now conducted
     and as presently proposed to be conducted,

          (iii)  has all necessary licenses, certificates and permits to own and
     operate its Properties and to carry on its business as now conducted and as
     presently proposed to be conducted, except where the failure to have any
     such licenses, certificates and permits, together with all other such
     failures, would not be likely to have a material and adverse effect on the
     business or financial condition of the Company and the Subsidiaries, taken
     as a whole, or the ability of the Company to perform its obligations set
     forth in this Agreement and in the Notes, and

          (iv) has duly qualified or has been duly licensed, and is authorized
     to do business and is in good standing as a foreign corporation, except
     where the failure to be so qualified, licensed and authorized in any

     of the Company and the Subsidiaries, taken as a whole, or the ability of
     the Company to perform its obligations set forth in this Agreement and in
     the Notes.

The revenues and net income of the Company for the fiscal year ended July 31,
1992, and the total assets of the Company as of July 31, 1992, in each case
exceed ninety percent (90%) of

                                     A-32
<PAGE>
 
the consolidated revenues, consolidated net income, and consolidated assets of
the Company and the Subsidiaries for such period and at such time.

     8C.  FINANCIAL STATEMENTS.  The Company has furnished each Purchaser with
the following financial statements, identified by a principal financial officer
of the Company:

          (i) a consolidated balance sheet of the Company and its subsidiaries
     as at July 31 in each of the years 1990 to 1993, inclusive, and
     consolidated statements of income, stockholders' equity and cash flows of
     the Company and its subsidiaries for each such year, all reported on by
     Deloitte & Touche; and

     as at January 30, 1994 and January 31, 1993 and consolidated statements of
     income and cash flows for the three month period ended on each such date,
     prepared by the Company.

Such financial statements (including any related schedules and/or notes) are
true and correct in all material respects (subject, as to interim statements, to
changes resulting from audits and year-end adjustments), have been prepared in
accordance with generally accepted accounting principles as in effect at such
time and consistently followed throughout the periods involved (except as
otherwise noted therein) and show all liabilities, direct and contingent, of the
Company and its subsidiaries required to be shown in accordance with such
principles.  The balance sheets fairly present the condition of the Company and
its subsidiaries as at the dates thereof, and the statements of income,
stockholders' equity and cash flows fairly present the results of the operations
of the Company and its subsidiaries and their cash flows for the periods
indicated.  There has been no material adverse change in the business, condition
(financial or otherwise) or operations of the Company and the Subsidiaries taken
as a whole since July 31, 1993, except for charges in the third Fiscal Quarter
of Fiscal Year 1994 to shareholders' equity in connection with the increases in
the underfunded status of the Company's pension plans, and to income in
connection with the expensing of unamortized pension benefit past service costs,
each as described in the Company's Quarterly Report on Form 10-Q for Fiscal
Quarter ended January 30, 1994.

pending or, to the knowledge of the Company, threatened against the Company or
any of the Subsidiaries, or any properties or rights of the Company or any of
the Subsidiaries, by or before any court, arbitrator or administrative or
governmental body would result in any material adverse change in the business,
condition (financial or otherwise) or operations of the Company and the
Subsidiaries taken as a whole.

     8E.  OUTSTANDING DEBT.  Neither the Company nor any of the Subsidiaries has
outstanding any Debt except as permitted by paragraph 6C hereof.  There exists
no default under the provisions of any instrument evidencing such Debt or of any
agreement relating thereto.

reflected in the balance sheet as at January 30, 1994 referred to in paragraph
8C(ii) hereof (other than Properties disposed of in the ordinary course of

hereof.  All leases necessary in any material respect for the conduct of the
respective businesses of the Company and the Subsidiaries are valid and

reserves have been established in accordance with generally accepted accounting
principles.

          (I) RESTRICTIONS.  Neither the Company nor any of the Subsidiaries is
     a party to any contract or agreement or subject to any charter or bylaw
     restriction that would, in the aggregate with all other such contracts,

     any violation of, or result in the creation of any Lien upon any of the
     Properties of the Company or any of the Subsidiaries pursuant to, the
     charter or bylaws of the Company or any of the Subsidiaries, any award of
     any arbitrator or any agreement (including any agreement with
     stockholders), instrument, order, judgment, decree, statute, law, rule or
     regulation to which the Company or any of the Subsidiaries is subject.

          (III)  RESTRICTIONS ON DEBT.  Neither the Company nor any of the

the Notes will be used to repay Debt of the Company, to reduce the amount of
receivables sold pursuant to the Trade Receivables Agreement and for general
corporate purposes.  None of such proceeds will be used, directly or indirectly,
for the purpose, whether immediate, incidental or ultimate, of purchasing or
carrying any margin stock or for the purpose of maintaining, reducing or
retiring any Debt which was originally incurred to purchase or carry any stock
that is currently a margin stock or for any other purpose which might constitute
this transaction a "purpose credit" within the meaning of such Regulation G.
Neither the Company nor any agent acting on its behalf has taken or will take
any action which might cause this Agreement or the Notes to violate Regulation

ERISA Affiliate which is or would be materially adverse to the business,
condition (financial or otherwise) or operations of the Company and the
Subsidiaries taken as a whole.  Neither the Company, any Subsidiary nor any
ERISA Affiliate has incurred or presently expects to incur any withdrawal

Notes will be exempt from, or will not involve any transaction which is subject
to, the prohibitions of section 406 of ERISA and will not involve any
transaction in connection with which a penalty could be imposed under section
502(i) of ERISA or a tax could be imposed pursuant to section 4975 of the IRC.
The representation by the Company in the next preceding sentence is made in
reliance upon and subject to the accuracy of each Purchaser's representation in
paragraph 9B hereof.

     8M.  GOVERNMENTAL CONSENT.  Neither the nature of the Company or of any
Subsidiary, nor any of their respective businesses or Properties, nor any
relationship between the Company or any Subsidiary and any other Person, nor any
circumstance in connection with the offering, issuance, sale or delivery of the
Notes is such as to require any authorization, consent, approval, exemption or
other action by or notice to or filing with any court or administrative or
governmental body (other than routine filings after the Closing Date with either
or both of the Securities and Exchange Commission and state Blue Sky
authorities) in connection with the execution and delivery of this Agreement,

their respective properties and facilities have complied at all times and in all
respects with all federal, state, local and regional statutes, laws, ordinances
and judicial or administrative orders, judgments, rulings and regulations
relating to protection of the environment except, in any such case, where
failure to comply would not result in a material adverse effect on the business,
condition (financial or otherwise) or operations of the Company and the
Subsidiaries taken as a whole.

     8O.  DISCLOSURE.  Neither this Agreement nor any other document,
certificate or statement furnished to any Purchaser by or on behalf of the
Company in connection herewith contains any untrue statement of a material fact
or omits to state a material fact necessary in order to make the statements
contained herein and therein not misleading.  There is no fact peculiar to the
Company or any of the Subsidiaries that in the future (so far as the Company can
now foresee) would, in the aggregate with all other such facts, be more likely
than not to have a material and adverse effect on the business or financial
condition of the Company and the Subsidiaries, taken as a whole, or the ability
of the Company to perform its obligations set forth in this Agreement and in the
Notes and that has not been set forth in this Agreement or in the other

          (ii) has failed to obtain any license, certificate, permit, franchise
     or other governmental authorization necessary to the ownership of its
     Property or to the conduct of its business;

which violation or failure to obtain is more likely than not to have, in the
aggregate with all other such violations or failures, a material and adverse
effect on the business or financial condition of the Company and the
Subsidiaries, taken as a whole, or the ability of the Company to perform its
obligations set forth in this Agreement and in the Notes.

constitutes assets allocated to any separate account maintained by such
Purchaser in which any employee benefit plan, other than employee benefit plans

participates to the extent of ten percent (10%) or more.  For the purpose of
this paragraph 9B, the terms "separate account" and "employee benefit plan"

     "CALLED PRINCIPAL" shall mean, with respect to any Note, the principal of
such Note that is to be prepaid or purchased pursuant to paragraph 4B, paragraph
4.E or paragraph 5I hereof (any partial prepayment being applied in satisfaction
of required payments of principal in inverse order of their scheduled due dates)
or is declared to be immediately due and payable pursuant to paragraph 7A
hereof, as the context requires.

     "DISCOUNTED VALUE" shall mean, with respect to the Called Principal of any
Note, the amount obtained by discounting all Remaining Scheduled Payments with
respect to such Called Principal from their respective scheduled due dates to
the Settlement Date with respect to such Called Principal, in accordance with
accepted financial practice and at a discount factor (applied on the same
periodic basis as that on which interest on the Notes is payable) equal to the
Reinvestment Yield with respect to such Called Principal.

     "REINVESTMENT YIELD" shall mean, with respect to the Called Principal of
any Note, the yield to maturity implied by

               (i) the yields reported, as of 10:00 a.m. (New York City time) on
          the Business Day next preceding the Settlement Date with respect to
          such Called Principal, on the display designated as "Page 678" on the
          Telerate Service (or such other display as may replace Page 678 on the
          Telerate Service) for actively traded U.S. Treasury securities having
          a maturity equal to the Remaining Average Life of such Called
          Principal as of such Settlement Date, or if such yields shall not be
          reported as of such time or the yields reported as of such time shall
          not be ascertainable,

               (ii) the Treasury Constant Maturity Series yields reported, for
          the latest day for which such yields shall have been so reported as of
          the Business Day next preceding the Settlement Date with respect to
          such Called Principal, in Federal Reserve Statistical Release H.15
          (519) (or any comparable successor publication) for actively traded
          U.S. Treasury securities having a constant maturity equal to the
          Remaining Average Life of such Called Principal as of such Settlement
          Date.

                                     A-38
<PAGE>
 
     Such implied yield shall be determined, if necessary, by (a) converting
     U.S. Treasury bill quotations to bond-equivalent yields in accordance with
     accepted financial practice and (b) interpolating linearly between yields
     reported for various maturities.  Reinvestment Yield calculated as
     aforesaid shall be increased by twenty-five one-hundredths percent (0.25%)
     per annum in the case of any Settlement Date occurring after December 15,
     1998.

     Principal of any Note, the number of years (calculated to the nearest one-
     twelfth year) obtained by dividing

               (i)  such Called Principal into

               (ii) the sum of the products obtained by multiplying

                    (a) each Remaining Scheduled Payment of such Called
               Principal (but not of interest thereon) by

                    (b) the number of years (calculated to the nearest one-
               twelfth year) which will elapse between the Settlement Date with

          that the aggregate amount available need not exceed the Acceptable

               utilizing the Acceptable Availability to it under such credit
               facility at any time during the term of such credit facility or,
               prior to January 25, 1997, that were more onerous than those

accrue which were carried by the Note so exchanged or transferred, so that
neither gain nor loss of interest shall result from any such transfer or
exchange.  Upon receipt of written notice from the holder of any Note of the
loss, theft, destruction or mutilation of such Note and, in the case of any such
loss, theft or destruction, upon receipt of such holder's unsecured indemnity
agreement, or in the case of any such mutilation upon surrender and cancellation
of such Note, the Company will make and deliver a new Note, of like tenor, in
lieu of the lost, stolen, destroyed or mutilated Note.

used in the preparation of such financial statements hereafter occasioned by the
promulgation of rules and regulations by or required by the Financial Accounting
Standards Board, the Cost Accounting Standards Board or the Securities and
Exchange Commission (or successors thereto or agencies with similar functions)

the Company to the holders of Notes or by a holder of Notes to the Company, to
enter into negotiations in order to amend paragraph 6 and the Financial
Covenants incorporated by reference herein, as applicable, so as to equitably
reflect such change with the desired result that the criteria for evaluating the
Company's financial condition shall be the same after such change as if such
change had not been made.

agreements and understandings relating to the subject matter hereof.

transaction (the "Transaction Date") giving rise to the need to calculate the
Consolidated Fixed Charge Coverage Ratio (such four full fiscal quarter period
being referred to herein as the "Four Quarter Period") to (b) the aggregate
Consolidated Fixed Charges of such Person for such Four Quarter Period.  For
purposes of this definition, if the Transaction Date occurs prior to the first
anniversary of the Issue Date, EBITDA and Consolidated Fixed Charges shall be
calculated, in the case of the Company, after giving effect on a pro forma basis
as if the issuance of the Senior Notes and the application of the net proceeds
therefrom occurred on the first day of the Four Quarter Period.  In addition to
and without limitation of the foregoing, for purposes of this definition, EBITDA
and Consolidated Fixed Charges shall be calculated after giving effect on a pro
forma basis for the period of such calculation to (x) the incurrence or
retirement, as the case may be, of any Indebtedness (including Acquired
Indebtedness) of such Person or of any of its Subsidiaries during the period
commencing on the first day of the Four Quarter Period to and including the

incurrence of the Indebtedness giving rise to the need to make such calculation,
as if such incurrence or retirement, as the case may be, occurred on the first
day of the Reference Period and (y) the EBITDA attributable to any Person,
business, property or asset acquired or divested during the Reference Period
(provided that with respect to any such acquisition, only to the extent the
EBITDA of such Person is otherwise includible in the referent Person's

                                       4
<PAGE>
 
EBITDA) as if such transaction occurred on the first day of the Reference
Period.  Furthermore, in calculating "Consolidated Fixed Charges" for purposes
of determining the denominator (but not the numerator) of this "Consolidated
Fixed Charge Coverage Ratio," (i) interest on Indebtedness determined on a
fluctuating basis as of the Transaction Date and which will continue to be so
determined thereafter shall be deemed to have accrued at a fixed rate per annum
equal to the rate of interest on such Indebtedness in effect on the Transaction
Date; (ii) if interest on any Indebtedness actually incurred on the Transaction
Date may be optionally determined at an interest rate based upon a factor of a
prime or similar rate, a eurocurrency interbank offered rate or other rates,
then the interest rate in effect on the Transaction Date will be deemed to have
been in effect during the entire Reference Period; and (iii) notwithstanding the
foregoing, interest on Indebtedness determined on a fluctuating basis, to the
extent such interest is covered by Interest Rate Protection Agreements, shall be
deemed to accrue at the rate per annum resulting after giving effect to the
operation of such agreements.

period, the sum of, without duplication, the amounts for such period, taken as a

otherwise (except dividends payable in shares of Common Stock) paid, accrued or
scheduled to be paid or accrued during such period multiplied by (ii) a
fraction, the numerator of which is one and the denominator of which is one

amortization of original issue discount, the interest component of Capitalized
Lease Obligations, net cash costs under all Interest Rate Protection Agreements
(including amortization of fees), all capitalized interest, the interest portion
of any deferred payment obligations for such period and cash contributions to
any employee stock ownership plan to the extent such contributions are used by
such employee stock ownership plan to pay interest or fees to any Person (other
than the referent Person or one of its Wholly Owned Subsidiaries) in connection
with loans incurred by such employee stock ownership plan to purchase capital
stock of the referent Person, but net of any amortization of any debt issuance
costs.  If the Person for whom this calculation is being made or any of its
Subsidiaries directly or indirectly guarantees Indebtedness of a third person,
the calculation shall give effect to the incurrence of such guaranteed
Indebtedness as if such Person or Subsidiary of such Person had directly
incurred or otherwise assumed such guaranteed Indebtedness as of the first day
of the Reference period.

     "Consolidated Net Income" means, with respect to any Person for any period,
the consolidated net income (or deficit) of such Person and its Consolidated

period, on a consolidated basis, as determined in accordance with GAAP
consistently applied, provided that the net income of any other Person (other
than a Subsidiary) in which the referent Person or any Subsidiary of the
referent Person has a joint interest with a third party (which interest does not
cause the net income of such other Person to be consolidated into the net income
of the referent Person in accordance with GAAP) shall be included only to the
extent of the lesser of (a) such net income that has been actually received by
the referent Person or Wholly Owned Subsidiary of the referent Person in the
form of cash dividends or similar cash distributions (subject to, in the case of
a dividend or other distribution to a Wholly Owned Subsidiary of the referent
Person, the limitations set forth in clause (i)(1) of the next proviso hereof)
or (b) the net income of such other Person (which in no event shall be less than
zero); provided further, that there shall be excluded (i)(1) the net income (but
not loss) of any Subsidiary of the referent Person to the extent that the
declaration or payment of dividends or similar distributions by such Subsidiary
is not permitted by operation of the terms of its charter or any agreement,
instrument, judgment, decree, order, statute, rule or governmental regulation
applicable to such Subsidiary, (2) the net income of any Person acquired in a
pooling of interests transaction accrued prior to the date it became a
Subsidiary of the referent Person, and (3) all gains and losses resulting from
the cumulative effect of any accounting change pursuant to the application of
Accounting Principles Board Opinion No. 20, as amended, or any successor
thereto; (ii) any gain (but not loss), net of any related provisions for taxes,
realized upon the sale or other disposition (including, without limitation,
dispositions pursuant to Sale-Leaseback Financings) of any property or assets
which are not sold or otherwise disposed of in the ordinary course of business

any related provision for taxes on any such extraordinary gain; (v) any amounts
paid or accrued as dividends on Preferred Stock of such Person or Preferred
Stock of any Subsidiary of such Person; (vi) income or loss attributable to

or other write-ups subsequent to the Issue Date in the book value of any asset
owned by such Person or a Consolidated Subsidiary and (c) any amounts
attributable to the cost of treasury stock and the principal amount of any
promissory notes receivable from the sale of Capital Stock of such Person or of
any of its Subsidiaries.  Notwithstanding any of the foregoing, net deferred
income tax assets recorded in accordance with Statement of Financial Accounting
Standards No. 109, Accounting for Income Taxes ("SFAS 109"), shall be calculated
without regard to any valuation allowance with respect to such net deferred tax
asset recorded by the Company in accordance with SFAS 109.

                                The Senior Notes

SECTION 2.01   Form and Dating.
               --------------- 

     The Senior Notes and the Trustee's certificate of authentication relating
thereto shall be substantially in the form set forth in Exhibit A, which is part
of this Indenture, with such appropriate insertions, omissions, substitutions
and other variations as are required or permitted by this Indenture. The Senior
Notes may have notations, legends or endorsements required by law, stock
exchange rule or usage. The Company shall approve the form of the Senior Notes
and any notation, legend or endorsement on them. Each Senior Note shall be dated

     The terms and provisions contained in the Senior Notes shall constitute,
and are hereby expressly made, a part of this Indenture and, to the extent
applicable, 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.

                                       22
<PAGE>
 
SECTION 2.02  Execution and Authentication.
              ---------------------------- 

     Two Officers shall sign the Senior Notes for the Company by manual or
facsimile signature. The Company's seal shall be reproduced on the Senior Notes.

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

     A Senior Note shall not be valid until authenticated by the manual
signature of the Trustee. The signature shall be conclusive evidence that the
Senior Note has been authenticated under this Indenture.

     Upon a written order of the Company signed by an Officer of the Company,
the Trustee shall authenticate Senior Notes for original issue up to the
aggregate principal amount stated in paragraph 4 of the Senior Notes. The
aggregate principal amount of Senior Notes outstanding at any time may not
exceed that amount except as provided in Section 2.07.

     The Senior Notes shall be issuable only in registered form without coupons
and only in denominations of $1,000 or any integral multiple thereof.

     The Trustee may appoint an authenticating agent acceptable to the Company
to authenticate Senior Notes. An authenticating agent may authenticate Senior
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 right as an Agent to deal with the Company or
an Affiliate of the Company.

SECTION 2.03  Registrar and Paying Agent.
              -------------------------- 

     The Company shall maintain or cause to be maintained in the Borough of
Manhattan, New York, New York (the "New York Office"), and in such other
locations as it shall determine, an office or agency: (a) where securities may
be presented for registration of transfer or for exchange ("Registrar"); (b)
where Senior Notes may be presented for payment ("Paying Agent"); and (c) where
notices and demand to or upon the Company in respect of Senior Notes and this
Indenture may be served by the holders of Senior Notes. The Registrar shall keep
a register of the Senior Notes and of their transfer and exchange. The Company
may appoint one or more co-registrars and one or more additional paying agents.
The term "Paying Agent" includes any additional paying agent. The Company may
change any Paying Agent, Registrar or co-registrar without prior notice. The
Company shall notify the Trustee of the name and address of any Agent not a
party to this Indenture and shall enter into an appropriate agency agreement
with any Registrar, Paying Agent or co-registrar not a party to this Indenture.
The agreement shall implement the provisions of this Indenture that relate to
such Agent. The Company or any of its Subsidiaries may act as Paying Agent,
Registrar or co-registrar, except that for purposes of Articles 3 and 8 and
Sections 4.10 and 4.16, neither the Company nor any of its Subsidiaries shall
act as Paying Agent. If the Company fails to appoint or maintain

                                       23
<PAGE>
 
another entity as Registrar or Paying Agent, the Trustee shall act as such, and
the Trustee shall initially act as such. The Trustee shall cause the New York
Office to be maintained as long as it acts as Registrar or Paying Agent.

SECTION 2.04  Paying Agent To Hold Money in Trust.
              ----------------------------------- 

     The Company shall require each Paying Agent (other than the Trustee, who
hereby so agrees), to agree in writing that the Paying Agent will hold in trust
for the benefit of holders of Senior Notes or the Trustee all money held by the
Paying Agent for the payment of principal or interest on the Senior Notes, and
will notify the Trustee of any default by the Company in respect of making any
such payment. While any such default continues, the Trustee may require a Paying
Agent to 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
over to the Trustee, the Paying Agent (if other than the Company or a Subsidiary
of the Company) shall have no further liability for the money. If the Company or
a Subsidiary of the Company acts as Paying Agent, it shall segregate and hold in
a separate trust fund for the benefit of the holders of Senior Notes all money
held by it as Paying Agent.

SECTION 2.05  Holder Lists.
              ------------ 

     The Trustee shall preserve in as current a form as is reasonably
practicable the most recent list available to it of the names and addresses of
holders of Senior Notes. If the Trustee is not the Registrar, the Company shall
furnish to the Trustee at least seven 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 reasonably require of the names and
addresses of holders of Senior Notes.

SECTION 2.06  Transfer and Exchange.
              --------------------- 

     Where Senior Notes are presented to the Registrar or a co-registrar with a
request to register a transfer or to exchange them for an equal principal amount
of Senior Notes for other denominations, the Registrar shall register the
transfer or make the exchange if its requirements for such transactions are met.
To permit registrations of transfers and exchanges, the Company shall issue and
the Trustee shall authenticate Senior Notes at the Registrar's request. No
service charge shall be made for any registration of transfer or exchange
(except as otherwise expressly permitted herein), but the Company may require
payment of a sum sufficient to cover any transfer tax or similar governmental
charge payable upon exchanges pursuant to Sections 2.10, 3.06 or 9.05.

     The Company shall not be required (a) to issue, register the transfer of or
exchange Senior Notes during a period beginning at the opening of business 15
days before the day of any selection of Senior Notes for redemption under
Section 3.02 and ending at the close of business on the day of selection, or (b)
to register the transfer or exchange of any Senior Note so selected

                                       24
<PAGE>
 
for redemption in whole or in part, except the unredeemed portion of any Senior
Note being redeemed in part.

SECTION 2.07  Replacement Senior Notes.
              ------------------------ 

     If the holder of a Senior Note claims that the Senior Note has been lost,
destroyed or wrongfully taken, the Company shall issue and the Trustee shall
authenticate a replacement Senior Note if the Trustee's requirements are met. If
required by the Trustee or the Company as a condition of receiving a replacement
Senior Note, the holder of Senior Note must provide an indemnity bond
sufficient, in the judgment of both the Company and the Trustee, to fully
protect the Company, the Trustee, any Agent and any authenticating agent from
any loss which any of them may suffer if the Senior Note is replaced. The
Company and the Trustee may charge the relevant holder for their expenses in
replacing any Senior Note.

     Every replacement Senior Note is an additional obligation of the Company.

SECTION 2.08  Outstanding Senior Notes.
              ------------------------ 

     The Senior Notes outstanding at any time are all the Senior Notes properly
authenticated by the Trustee except for those cancelled by the Trustee, those
delivered to it for cancellation, and those described in this Section as not
outstanding.

     If a Senior Note is replaced pursuant to Section 2.07, it ceases to be
outstanding unless the Trustee receives proof satisfactory to it that the
replaced Senior Note is held by a bona fide purchaser.

     If Senior Notes are considered paid under Section 4.01, they cease to be
outstanding and interest on them ceases to accrue.

     A Senior Note does not cease to be outstanding because the Company or an
Affiliate of the Company holds the Senior Note.

SECTION 2.09  When Treasury Senior Notes Disregarded.
              -------------------------------------- 

     In determining whether the holders of the required principal amount of
Senior Notes have concurred in any direction, waiver or consent, Senior Notes
owned by the Company or an Affiliate of the Company shall be considered as
though they are 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 Senior Notes which the Trustee knows are so owned shall be so
disregarded.

                                       25
<PAGE>
 
SECTION 2.10  Temporary Senior Notes.
              ---------------------- 

     Until definitive Senior Notes are ready for delivery, the Company may
prepare and the Trustee shall authenticate temporary Senior Notes. Temporary
Senior Notes shall be substantially in the form of definitive Senior Notes but
may have variations that the Company considers appropriate for temporary Senior
Notes. If temporary Senior Notes are issued, the Company will cause definitive
Senior Notes to be prepared without unreasonable delay. After the preparation of
definitive Senior Notes, the temporary Senior Notes shall be exchangeable for
definitive Senior Notes upon surrender of the temporary Senior Notes at any
office or agency of the Company designated pursuant to Section 2.03 without
charge to the holder. Upon surrender for cancellation of any one or more
temporary Senior Notes the Company shall execute and the Trustee shall
authenticate and deliver in exchange therefor a like principal amount of
definitive Senior Notes of authorized denominations. Until so exchanged, the
temporary Senior Notes shall in all respects be entitled to the same benefits
under this Indenture as definitive Senior Notes.

SECTION 2.11  Cancellation.
              ------------ 

     The Company at any time may deliver Senior Notes to the Trustee for
cancellation. The Registrar and Paying Agent shall forward to the Trustee any
Senior Notes surrendered to them for registration of transfer, exchange or
payment. The Trustee and no one else shall cancel Senior Notes surrendered for
registration of transfer, exchange, payment, replacement or cancellation and
shall dispose of cancelled Senior Notes as the Company directs. The Company may
not issue new Senior Notes to replace Senior Notes that it has paid or that have
been delivered to the Trustee for cancellation.

SECTION 2.12  Defaulted Interest.
              ------------------ 

     If the Company fails to make a payment of interest on the Senior Notes, it
shall pay such defaulted interest plus, to the extent lawful, any interest
payable on the defaulted interest. It may pay such defaulted interest, plus any
such interest payable on it, to the persons who are holders of Senior Notes on a
subsequent special record date. The Company shall fix any such record date and
payment date. At least 15 days before any such record date, the Company shall
mail to holders of Senior Notes a notice that states the record date, payment
date and amount of such interest to be paid.

SECTION 2.13  CUSIP Number.
              ------------ 

     The Company in issuing the Senior Notes may use a "CUSIP" number, and if
so, such CUSIP number shall be included in notices of redemption or exchange as
a convenience to holders of Senior Notes; provided, however, that any such
notice may state that no representation is made as to the correctness or
accuracy of the CUSIP number printed in the notice or on the Senior Notes and
that reliance may be placed only on the other identification numbers printed

                                       26
<PAGE>
 
on the Senior Notes. The Company will promptly notify the Trustee of any change
in the CUSIP number.

     If the Company elects to redeem Senior Notes pursuant to the optional
redemption provisions of paragraph 5 of the Senior Notes, it shall notify the
Trustee of the redemption date and the principal amount of Senior Notes to be
redeemed. The redemption price shall be the amount determined pursuant to
paragraph 5 of the Senior Notes.

satisfactory to the Trustee).

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

     If less than all the Senior Notes are to be redeemed, the Trustee shall

that the Trustee considers fair and appropriate. The Trustee shall make the
selection not more than 75 days and not less than 30 days before the redemption
date from Senior Notes outstanding not previously called for redemption. The
Trustee may select for redemption a portion of the principal of Senior Note that
has a denomination larger than $1,000. Senior Notes and portions thereof will be
redeemed in the amount of $1,000 or integral multiples of $1,000. Provisions of
this Indenture that apply to Senior Notes called for redemption also apply to
portions of Senior Notes called for redemption. The Trustee will make the
selection of Senior Notes outstanding and not previously called for redemption.
The Trustee shall notify the Company promptly of the Senior Notes or portions of
Senior Notes to be called for redemption.

SECTION 3.03  Notice of Redemption.
              -------------------- 

     At least 30 days but not more than 60 days before a redemption date, the
Company shall mail a notice of redemption to each holder whose Senior Notes are
to be redeemed.

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

          (a) the redemption date;

          (b) the redemption price;

                                       27
<PAGE>
 
          (c) if any Senior Note is being redeemed in part, the portion of the
     principal amount of such Senior Note to be redeemed and that, after the
     redemption date, upon surrender of such Senior Note, a new Senior Note or
     Senior Notes in principal amount equal to the unredeemed portion will be
     issued;

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

          (e) that interest on Senior Notes called for redemption and for which
     funds have been set apart for payment, ceases to accrue on and after the
     redemption date (unless the Company defaults in the payment of the
     redemption price);

          (f) the paragraph of the Senior Notes pursuant to which the Senior
     Notes are being redeemed;

          (g) the aggregate principal amount of Senior Notes that are being
     redeemed;

          (h) the CUSIP number of the Senior Notes (provided that the disclaimer
     permitted by Section 2.13 may be made); and

          (i) the name and address of the Paying Agent.

     At the Company's request, the Trustee shall give notice of redemption in
the Company's name and at its expense.

SECTION 3.04   Effect of Notice of Redemption.
               ------------------------------ 

     Once notice of redemption is mailed, Senior Notes called for redemption
become due and payable on the redemption date at the price set forth in the
Senior Note.

SECTION 3.05   Deposit of Redemption Price.
               --------------------------- 

     On or before the redemption date, the Company shall deposit with the
Trustee or with the Paying Agent money in immediately available funds sufficient
to pay the redemption price of and accrued interest on all Senior Notes to be
redeemed on that date.  The Trustee or the Paying Agent shall return to the
Company any money not required for that purpose.

SECTION 3.06   Senior Notes Redeemed in Part.
               ----------------------------- 

     Upon surrender of a Senior Note that is redeemed in part, the Company shall

expense of the Company a new Senior Note equal in principal amount to the
unredeemed portion of the Senior Note surrendered.

     The Company shall pay the principal of and interest on the Senior Notes on

interest shall be considered paid on the date due if the Trustee or Paying Agent

register of the Senior Notes copies of the annual reports and of the
information, documents and other reports which the Company is required to file
with Commission pursuant to Section 13 or 15(d) of the Exchange Act or which the
Company would be required to file with the Commission if the Company then had a
class of securities registered under the Exchange Act.  In addition, the Company
shall cause its annual report to stockholders and any quarterly or other
financial reports furnished to its stockholders generally to be filed with the
Trustee, no later than the date such materials are mailed or made available to
the Company's stockholders, and thereafter mailed promptly to the holders of
Senior Notes at their addresses as set forth in the register of Senior Notes.

SECTION 4.03   Compliance Certificate.
               ---------------------- 

     The Company shall deliver to the Trustee, within 60 days after the end of
the first three fiscal quarters and within 120 days after the end of each fiscal
year of the Company, an Officers' Certificate stating that a review of the
activities of the Company and its Subsidiaries during the preceding fiscal
period has been made under the supervision of the signing Officers with a view
to determining whether the Company has fully performed its obligations under
this Indenture and further stating, as to each such Officer signing such
certificate, that to the best of his or her knowledge the Company has kept,
observed, performed and fulfilled each and every covenant contained in this
Indenture and is not in default in the performance or observance of any of the
terms and conditions hereof (or, if any Default or Event of Default shall have
occurred, describing all such Defaults or Events of Default of which he or she
may have

                                       29
<PAGE>
 
knowledge) and that to the best of his or her knowledge no event has occurred
and remains in existence by reason of which payments on account of the principal
of or interest on the Senior Notes are prohibited.

     The Company shall, so long as any of the Senior Notes are outstanding,
deliver to the Trustee, forthwith upon becoming aware of any Default, Event of
Default or default in the performance of any term or condition in this
Indenture, without regard to any period of grace or requirement of notice
provided hereunder, an Officers' Certificate specifying such Defaults, Event of
Default or default.

     So long as not contrary to the then current recommendations of the American
Institute of Certified Public Accountants, at the time the Officers' Certificate
described in the second preceding paragraph is filed with respect to any fiscal
year end of the Company, the Company also shall file with the Trustee a letter
or statement of the independent accountants who shall have certified the
financial statements of the Company for its preceding fiscal year in connection
with the annual report of the Company to its stockholders for such year to that
effect that, in making the examination necessary for certification of such
financial statements, nothing came to their attention that would lead them to
believe that the Company has violated any of the terms or conditions contained
in Sections 4.05, 4.06 and 4.09 of this Indenture, which Default remains uncured
at the date of such letter or statement or, if they shall have obtained
knowledge of any such uncured Default, specifying in such letter or statement
such Default or Defaults and the nature thereof, it being understood that such
accountants shall not be liable directly or indirectly for failure to obtain
knowledge of any such Default or Defaults and that their examination was not
directed primarily toward obtaining knowledge of such non compliance.

SECTION 4.04   Maintenance of Office or Agency.
               ------------------------------- 

     The Company shall maintain or cause to be maintained the office or agency
required under Section 2.03.  The Company shall give prompt written notice to
the Trustee of the location, and any change in the location, of such office or
agency not maintained by the Trustee.

     The Company may also from time to time designate one or more other offices
or agencies where the Senior Notes may be presented or surrendered for any or
all such purposes and may from time to time rescind such designation; provided,
however, that no such designation or rescission shall in any manner relieve the
Company of its obligation to maintain or cause to be maintained an office or
agency in the City of New York for such purpose.

SECTION 4.05   Limitation on Indebtedness.
               --------------------------

of the proposed incurrence thereof or shall occur as a result of such proposed
incurrence and (b) after giving effect to such proposed incurrence

                                       30
<PAGE>
 
the Company's Consolidated Fixed Charge Coverage Ratio would be greater than 2.0

SECTION 4.06   Limitation on Restricted Payments.
               ---------------------------------

Subsidiaries to, directly or indirectly, make any Restricted Payment unless, at
the time of such proposed Restricted Payment, and on a pro forma basis
immediately after giving effect thereto:

          A.  no Default or Event of Default has occurred and is continuing;

          B.  the aggregate amount expended for all Restricted Payments
     subsequent to the Issue Date would not exceed the sum of:

               (1) 50% of aggregate Consolidated Net Income of the  Company (or
          if such Consolidated Net Income is a loss, minus 100% of such loss)
          earned on a cumulative basis during the period  beginning on May 2,
          1994 and ending on the last date of the Company's fiscal quarter
          immediately preceding such proposed  Restricted Payment; plus

               (2) 100% of the aggregate Net Equity Proceeds received by the
          Company from any Person (other than from a Subsidiary of the Company)
          from the issuance and sale subsequent to the Issue Date of Qualified
          Capital Stock of the Company (excluding (a) any  Qualified Capital
          Stock of the Company paid as a dividend on any Capital Stock of the
          Company or of any of its Subsidiaries or as interest on any
          Indebtedness of the Company or of any of its  Subsidiaries, (b) the
          issuance of Qualified Capital Stock upon the conversion of, or in
          exchange for, any Capital Stock of the Company or of any of its
          Subsidiaries and (c) any Qualified Capital Stock of the Company with
          respect to which the purchase price thereof has been financed directly
          or indirectly using funds (i) borrowed from or advanced by the Company
          or any of its Subsidiaries, unless and until and to the extent such
          borrowing advanced is repaid or (ii)  contributed or guaranteed by the
          Company or by any of its  Subsidiaries (including, without limitation,
          in respect of any  employee stock ownership or benefit plan) unless
          and until such guarantee terminates; and

          C.  The Company would be able to incur $1.00 of additional
     Indebtedness (other than Permitted Indebtedness) under Section 4.05
     (assuming a market rate of interest with respect thereto).

     The foregoing provisions of this covenant will not prevent: (a) the
payment of any dividend within 60 days after the date of its declaration if at
such date of declaration the payment of such dividend would comply with the
provisions set forth above, provided that (i) such dividend will be deemed to
have been paid as of its date of declaration for the purposes of this

                                       31
<PAGE>
 
covenant and (ii) at the time of payment of such dividend no other Default or
Event of Default shall have occurred and be continuing or would result
therefrom, (b) if no Default or Event of Default shall have occurred and be
continuing or would occur as a consequence thereof, the purchase, redemption,
retirement or acquisition of any shares of Capital Stock of the Company or of

the shares or other assets being so distributed at the time of such distribution
over the consideration, if any, received therefor.

SECTION 4.10   Limitation on Sale of Assets.
               ---------------------------- 

     The Company will not, and will not permit any of its Subsidiaries to,
consummate any Asset Sale unless such Asset Sale is for at least Fair Market
Value and at least 80% of the consideration therefrom received by the Company or
such Subsidiary is in the form of cash or Cash Equivalents.

     Following any Asset Sale, an amount equal to the Net Cash Proceeds of such
Asset Sale shall be applied by the Company or such Subsidiary within 365 days of
the date of the Asset Sale, at its election, to either:  (a) the payment of Pari
Passu Indebtedness with an equal and concurrent reduction in the commitment
related to such Pari Passu Indebtedness, if applicable, provided any Net Cash
Proceeds which are applied on such pro rata basis to reduce Indebtedness under
the Revolving Credit Agreement shall result in a permanent reduction of the
borrowing availability thereunder; (b) make any Permitted Program Investment or
any other investment in capital assets usable in the Company's or its
Subsidiaries' lines of business or in an asset or business in the same line of
business as the Company; or (c) a combination of payment and investment
permitted by the foregoing clauses (a) and (b).  On the earlier of (A) the 366th
day after the date of an Asset Sale or (B) such date as the Board of Directors
of the Company or of such Subsidiary determines (as evidenced by a written
resolution of said Board of Directors) not to apply an amount equal to the Net
Cash Proceeds relating to such Asset Sale as set forth in the immediately
preceding sentence (each of (A) and (B), an "Asset Sale Offer Trigger Date"),
the Company or such Subsidiary shall be obligated to apply an amount equal to
aggregate amount of Net Cash Proceeds which have not been applied on or before
such Asset Sale Offer

                                       35
<PAGE>

immediately preceding sentence (each an "Asset Sale Offer Amount") to make an
offer to purchase for cash (the "Asset Sale Offer") from all holders of Senior
Notes on a pro rata basis that amount of Senior Notes equal to the Asset Sale
Offer Amount at a price equal to 100% of the principal amount of the Senior
Notes to be repurchased, plus accrued and unpaid interest thereon to the date of
repurchase.  Notwithstanding the foregoing, if an Asset Sale Offer Amount is
less than $10 million, the application of such Asset Sale Offer Amount to an
Asset Sale Offer may be deferred until such time as such Asset Sale Offer Amount
plus the aggregate amount of all Asset Sale Offer Amounts arising subsequent to
such Asset Sale Offer Trigger Date from all Asset Sales by the Company and its
Subsidiaries aggregates at least $10 million, at which time the Company or such
Subsidiary shall apply all Asset Sale Offer Amounts that have been so deferred
to make an Asset Sale Offer (the first date the aggregate of all such deferred
Asset Sale Offer Amounts is equal to $10 million or more shall be deemed to be
an "Asset Sale Offer Trigger Date").

     In the event of the transfer of substantially all (but not all) of the
property and assets of the Company as an entirety to a Person in a transaction
permitted under Section 5.01, the successor corporation shall be deemed to have
sold the properties and assets of the Company not so transferred for purposes of
this covenant, and shall comply with the provisions of this covenant with
respect to such deemed sale as if it were an Asset Sale.

     Each Asset Sale Offer shall be mailed to the holders of the Senior Notes at
the addresses shown on the register of holders maintained by the Registrar with
a copy to the Trustee and the Paying Agent, within 10 days following the
applicable Asset Sale Offer Trigger Date, and shall comply with each of the
procedures for notice set forth below.  Each Asset Sale Offer shall remain open
until a specified date (the "Asset Sale Offer Termination Date") which is at
least 20 Business Days from the date such Asset Sale Offer is mailed.  During
the period specified in the Asset Sale Offer, holders of Senior Notes may elect
to tender their Senior Notes in whole or in part in integral multiples of $1,000
in exchange for cash.  Payment shall be made by the Company (or applicable
Subsidiary) in respect of Senior Notes properly tendered pursuant to this
Section on a specified Business Day (the "Asset Sale Offer Payment Date") which
shall be no earlier than three Business Days after the Asset Sale Offer
Termination Date and no later then 60 days after such applicable Asset Sale
Offer Trigger Date.  To the extent holders of Senior Notes properly tender
Senior Notes in an amount exceeding the Asset Sale Offer Amount, Senior Notes of
tendering holders will be repurchased on a pro rata basis (based on amounts
tendered).

     The notice, which shall govern the terms of the Asset Sale Offer, shall
include such disclosures as are required by law and shall state:

          (a) that the Asset Sale Offer is being made pursuant to this Section
     4.10;

     if any) for each Senior Note, the Asset Sale Offer Termination Date and the

                                       36
<PAGE>
 
          (c) that any Senior Note not tendered or accepted for payment will
     continue to accrue interest in accordance with the terms thereof;

          (d) that, unless the Company defaults on making the payment, any
     Senior Note accepted for payment pursuant to the Asset Sale Offer shall
     cease to accrue interest after the Asset Sale Offer Payment Date;

          (e) that holders electing to have Senior Notes purchased pursuant to
     an Asset Sale Offer will be required to surrender their Senior Notes to the
     Paying Agent at the address specified in the notice prior to 5:00 p.m., New
     York City time, on the Asset Sale Offer Termination Date and must complete
     any form letter of transmittal proposed by the Company and acceptable to
     the Trustee and the Paying Agent;

          (f) that holders of Senior Notes will be entitled to withdraw their
     election if the Paying Agent receives, not later than 5:00 p.m., New York
     City time, on the Asset Sale Offer Termination Date, a tested telex,
     facsimile transmission or letter setting forth the name of the holder, the
     principal amount of Senior Notes the holder delivered for purchase, the
     Senior Note certificate number (if any) and a statement that such holder is
     withdrawing his election to have such Senior Notes purchased;

          (g) that if Senior Notes in a principal amount in excess of the Asset
     Sale Offer Amount are tendered pursuant to the Asset Sale Offer, the
     Company shall purchase Senior Notes on a pro rata basis among the Senior
     Notes tendered (with such adjustments as may be deemed appropriate by the
     Company so that only Senior Notes in denominations of $1,000 or integral
     multiples of $1,000 shall be acquired);

          (h) that holders whose Senior Notes are purchased only in part will be
     issued new Senior Notes equal in principal amount to the unpurchased
     portion of the Senior Notes surrendered; and

          (i) the instructions that holders must follow in order to tender their
     Senior Notes.

     On the Asset Sale Offer Termination Date, the Company shall (i) accept for
payment Senior Notes or portions thereof tendered pursuant to the Asset Sale
Offer, (ii) deposit with the Paying Agent money sufficient to pay the purchase
price of all Senior Notes or portions thereof so tendered and accepted and (iii)
deliver to the Trustee the Senior Notes so accepted together with an Officers'
Certificate setting forth the Senior Notes or portions thereof tendered to and
accepted for payment by the Company.  On the Asset Sale Offer Payment Date, the
Paying Agent shall mail or deliver to the holders of Senior Notes so accepted
payment in an amount equal to the purchase price, and the Trustee shall promptly
authenticate and mail or deliver to such holders a new Senior Note equal in
principal amount to any unpurchased portion of the Senior Note surrendered.  Any
Senior Notes not so accepted shall be promptly mailed or delivered by the
Company to the holder thereof.

                                       37
<PAGE>
 
     If an offer is made to repurchase the Senior Notes pursuant to an Asset
Sale Offer, the Company will and will cause its Subsidiaries to comply with all
tender offer rules under state and Federal securities laws, including, but not
limited to, Section 14(e) under the Exchange Act and Rule 14e-1 thereunder, to
the extent applicable to such offer.  To the extent that the provisions of any
securities laws or regulations conflict with provisions of this Section 4.10,

shall not be deemed to have breached its obligations under this Section 4.10 by
virtue thereof.

     calculated as if the transaction (including the incurrence of any
     Indebtedness or Acquired Indebtedness) occurred on the first day of the
     Reference Period;

          (c) immediately before and after giving effect to such transaction and

     Subsidiary or such Person, as the case may be, could incur such
     Indebtedness (including Acquired Indebtedness) or create such Lien under
     this Indenture (giving effect to such Person being bound by all the terms
     of this Indenture).

<PAGE>
 
     interest is not fully cured prior to the expiration of the grace period
     provided in such Indebtedness on the date such interest payment was
     initially due), or any other payment obligation on any other Indebtedness
     (other than the Senior Notes) of the Company or of any Subsidiary of the

     incurred thereafter, having, individually or in the aggregate, an
     outstanding principal amount of $15,000,000 or more or (ii) any other

          (h) a court of competent jurisdiction enters a judgment, order or

SECTION 6.02   Acceleration.
               ------------ 

     If an Event of Default (other than an Event of Default specified in clauses
(g) and (h) of Section 6.01) occurs and is continuing, then and in every such
case the Trustee, by written notice to the Company, or the holders of at least
25% in aggregate principal amount of the then outstanding Senior Notes, by
written notice to the Company and the Trustee, may declare the unpaid principal
of and accrued interest on all the Senior Notes to be due and payable.  Upon
such declaration such principal amount, premium, if any, and accrued and unpaid
interest shall be immediately due and payable notwithstanding anything contained
in this Indenture or the Senior Notes to the contrary.  If an Event of Default
with respect to the Company specified in clauses (g) or (h) of Section 6.01
occurs, all unpaid principal of, and premium, if any, and accrued and unpaid
interest or, Senior Notes then outstanding shall automatically become and be
immediately due and payable without any declaration or other act on the part of
the Trustee or any holder of Senior Notes.

     The holders of a majority in principal amount of the then outstanding
Senior Notes by notice to the Trustee may rescind an acceleration and its
consequences if all existing Events of Default, other than the nonpayment of
principal and premium, if any, and interest on the Senior Notes which has become
due solely by virtue of such acceleration have been cured or waived and if the
rescission would not conflict with any judgment or decree of any court of
competent jurisdiction.  No such rescission shall affect any subsequent Default
or impair any right consequent thereto.

SECTION 6.03   Other Remedies.
               -------------- 

     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 the payment of
principal of or interest on the Senior Notes or to enforce the performance of
any provision of the Senior Notes or this Indenture.  The Trustee may maintain a
proceeding even if it does not possess any of the Senior Notes or does not
produce any of them in the proceeding.  A delay or omission by the Trustee or
any holder of a Senior 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 6.04   Waiver of Past Defaults.
               ----------------------- 

     The holders of a majority in aggregate principal amount of the Senior Notes
then outstanding may, on behalf of the holders of all the Senior Notes, waive an
existing Default or Event of Default and its consequences, except Default or
Event of Default in the payment of the principal of or interest on the Senior
Notes (other than nonpayment of principal of and premium,

                                       46
<PAGE>
 
if any, or interest on the Senior Notes which has become due solely by virtue of
an acceleration which has been duly rescinded, as provided above), or in respect
of a covenant or provision of this Indenture which cannot be modified or amended
without the consent of all holders of Senior Notes.  When a Default is waived,
it is cured and stops continuing.  No waiver shall extend to any subsequent or
other Default or impair any right consequent thereon.

SECTION 6.05   Control by Majority.
               ------------------- 

     The holders of a majority in principal amount of the then outstanding
Senior Notes 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, that the Trustee determines may be unduly
prejudicial to the rights of other holders of Senior Notes or that may involve
the Trustee in personal liability; provided that the Trustee may take any other
action the Trustee deems proper that is not inconsistent with such directions.

SECTION 6.06   Limitation on Suits.
               ------------------- 

     A holder of a Senior Note may not pursue any remedy with respect to this
Indenture or the Senior Notes unless:

          (a) the holder gives to the Trustee notice of a continuing Event of
     Default;

          (b) the holders of at least 25% in principal amount of the then
     outstanding Senior Notes make a request to the Trustee to pursue the
     remedy;

          (c) such holder or holders offer and, if requested, provide to the
     Trustee indemnity satisfactory to the Trustee against any loss, liability
     or expense;

          (d) the Trustee does not comply with the request within 60 days after
     receipt of the request and the offer and, if requested, the provision of
     indemnity; and

          (e) during such 60-day period the holders of a majority in principal
     amount of the then outstanding Senior Notes do not give the Trustee a
     direction inconsistent with the request.

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

SECTION 6.07   Rights of Holders To Receive Payment.
               ------------------------------------ 

     Notwithstanding any other provision of this Indenture, the right of any
holder of a Senior Note to receive payment of principal and interest on the
Senior Note, on or after the respective due dates expressed in the Senior Note,
or to bring suit for the enforcement of any such payment

                                       47
<PAGE>
 
on or after such respective dates, shall not be impaired or affected without the
consent of the holder of a Senior Note.

SECTION 6.08   Collection Suit by Trustee.
               -------------------------- 

     If an Event of Default specified in Section 6.01(a) or (b) occurs and is
continuing, the Trustee may recover judgment in its own name and as trustee of
an express trust against the Company for the whole amount of principal and
interest remaining unpaid on the Senior Notes and interest on overdue principal
and interest and such further amount as shall be sufficient to cover the costs
and, to the extent lawful, expenses of collection, including the reasonable
compensation, expenses, disbursements and advances of the Trustee, its agents
and counsel.

SECTION 6.09   Trustee May File Proofs of Claim.
               -------------------------------- 

     The Trustee may 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 and the
holders of Senior Notes allowed in any judicial proceedings relative to the
Company, its creditors or its property.  Nothing contained herein shall be
deemed to authorize the Trustee to authorize or consent to or accept or adopt on
behalf of any holder of a Senior Note any plan of reorganization, arrangement,
adjustment or composition affecting the Senior Notes or the rights of any holder
thereof, 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, it shall pay
out the money in the following order:

     First: to the Trustee for amounts due under Section 7.07, including payment
of all compensation, expenses and liabilities incurred, and all advances made,
by the Trustee, and the costs and expenses of collection;

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

     Third: to the Company.

     Except as otherwise provided in Section 2.12, the Trustee may fix a record
date and payment date for any payment to holders of Senior Notes.

                                       48
<PAGE>
 
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, a 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 pursuant to Section 6.07
or a suit by holders of more than 10% in principal amount of the then
outstanding Senior Notes.


                                   ARTICLE 7

                                  The Trustee

covenants and agrees to perform the same, as herein expressed.

SECTION 7.01   Duties of the 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 their exercise as a prudent person
would exercise or use under the circumstances in the conduct of his or her own
affairs.

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

          (i) The duties of the Trustee shall be determined solely by the
     express provisions of this Indenture and the Trustee need perform only

     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 they conform to the requirements of this Indenture.

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

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

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

     takes or omits to take in good faith in accordance with a direction

risk its own funds or incur any liability.  The Trustee may refuse to perform
any duty or exercise any right or power unless it receives indemnity
satisfactory to it 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 with the Company.  Money held in trust by the
Trustee need not be segregated from other funds except to the extent required by

to have been signed or presented by the proper person.  The Trustee need not
investigate any fact or matter stated in such a document.

SECTION 7.03   Individual Rights of the Trustee.
               -------------------------------- 

     The Trustee in its individual or any other capacity may become the owner or
pledgee of Senior Notes and may otherwise deal with the Company or an Affiliate
with the same rights it would have if it were not Trustee.  Any Agent may do the
same with like rights.  However, the Trustee is subject to Sections 7.10 and
7.11.

SECTION 7.04   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 Senior Notes, it shall not be
accountable for the Company's use of the proceeds from the Senior 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 Senior
Notes or any other document in connection with the sale of the Senior Notes or
pursuant to this Indenture other than its certificate of authentication.

SECTION 7.05   Notice of Defaults.
               ------------------ 

     If a Default or Event of Default occurs and is continuing and if it is
known to the Trustee, the Trustee shall mail to each holder of a Senior Note a
notice of the Default or Event of Default within 60 days after it occurs.  A
Default or an Event of Default shall not be considered known to the Trustee
unless it is a Default or Event of Default in the payment of principal or
interest when due under Section 6.01(a) or (b) or the Trustee shall have
received notice thereof, in accordance with this Indenture, from the Company or
from the holders of a majority in principal amount of the outstanding Senior
Notes.  Except in the case of a Default or Event of Default in payment of
principal or interest on any Senior Note, the Trustee may withhold the notice if
and so long as a committee of its Trust Officers in good faith determines that
withholding the notice is in the interest of the holders of Senior Notes.

SECTION 7.06   Reports by the Trustee to Holders.
               --------------------------------- 

     Within 60 days after the reporting date stated in Section 10.10, the
Trustee shall mail to holders of Senior Notes a brief report dated as of such
reporting date that complies with TIA (S) 313(a) (but if no event described in
TIA (S) 313(a) has occurred within twelve months preceding the reporting date,
no report need be transmitted).  The Trustee also shall comply with TIA (S)
313(b)(2).  The Trustee shall also transmit by mail all reports as required by
TIA (S) 313(c).

     A copy of each report at the time of its mailing to holders of Senior Notes
shall be filed with the Commission and each stock exchange, if any, on which the
Senior Notes are listed.  The Company shall notify the Trustee when the Senior
Notes are listed on any stock exchange.

                                       51

SECTION 7.07   Compensation and Indemnity.
               -------------------------- 

     The Company shall pay to the Trustee from time to time reasonable
compensation for its acceptance of this Indenture and its services hereunder.
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 may
include the reasonable compensation, disbursements and expenses of the Trustee's
agents and counsel.

     The Company shall indemnify the Trustee against any loss, liability or
expense incurred by it arising out of or in connection with the acceptance or
administration of its duties under this Indenture, except as set forth in the
next paragraph.  The Trustee shall notify the Company promptly of any claim for
which it may seek indemnity.  Failure by the Trustee to so notify the Company
shall not relieve the Company of its obligations hereunder.  The Company shall
defend the claim with counsel designated by the Company, who may be outside
counsel to the Company but shall in all events be reasonably satisfactory to the
Trustee, and the Trustee shall cooperate in the defense.  In addition, the
Trustee may retain one separate counsel and, if deemed advisable by such
counsel, local counsel, and the Company shall pay the reasonable fees and
expenses of such separate counsel and local counsel.  The indemnification herein
extends to any settlement, provided that the Company will not be liable for any
settlement made without its consent, provided, further, that such consent will
not be unreasonably withheld.

     The Company need not reimburse any expense or indemnify against any loss or
liability incurred by the Trustee through its own negligence or bad faith.

     To secure the Company's payment obligations in this Section 7.07, the
Trustee shall have a Lien prior to the Senior Notes on all money or property
held or collected by the Trustee, except that held in trust to pay principal and
interest on Senior Notes.  Such Liens 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 6.01(g) or (h) 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.

SECTION 7.08   Replacement of the 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 at any time and be discharged from the trust hereby
created by so notifying the Company.  The holders of a majority in principal
amount of the then outstanding

                                       52
<PAGE>
 
Senior Notes may remove the Trustee by so notifying the Trustee and the Company.
The Company may remove the Trustee if:

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

          (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 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 a successor
Trustee.  Within one year after the successor Trustee takes office, the holders
of a majority in principal amount of the then outstanding Senior 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 at least 10% in principal amount of the then outstanding Senior Notes
may petition any court of competent jurisdiction for the appointment of a
successor Trustee.

     If the Trustee after written request by any holder of a Senior Note who has
been a holder for at least six months fails to comply with Section 7.10, such
holder 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 Senior Notes.  The retiring Trustee shall promptly transfer all
property held by it as Trustee to the successor Trustee, provided that all sums
owing to the retiring Trustee hereunder have been paid and subject to the lien
provided for in Section 7.07.  Notwithstanding the replacement of the Trustee
pursuant to this Section 7.08, the Company's obligations under Section 7.07
shall continue for the benefit of the retiring Trustee.

SECTION 7.09   Successor Trustee by Merger, Etc.
               ---------------------------------

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

SECTION 7.10   Eligibility, Disqualification.
               ----------------------------- 

     This Indenture shall always have a Trustee who satisfies the requirements
of TIA (S) 310(a)(1).  The Trustee shall always have a combined capital and
surplus as stated in Section 10.10.  The Trustee is subject to TIA (S) 310(b)
regarding the disqualification of a trustee upon acquiring a conflicting
interest.

SECTION 7.11   Preferential Collection of Claims Against Company.
               ------------------------------------------------- 

     The Trustee shall comply with TIA (S) 311(a), excluding any creditor
relationship set forth in TIA (S) 311(b).  A Trustee who has resigned or been
removed shall be subject to TIA (S) 311(a) to the extent indicated therein.


                                   ARTICLE 8

                    Satisfaction and Discharge of Indenture

SECTION 8.01   Termination of Company's Obligations.
               ------------------------------------ 

     (i) This Indenture shall cease to be of further effect (except that the
Company's obligations under Section 7.07 and 8.03 shall survive) when all
outstanding Senior Notes theretofore authenticated and issued have been
delivered (other than destroyed, lost or stolen Senior Notes that have been
replaced or paid) to the Trustee for cancellation and the Company has paid all
sums payable hereunder.  In addition, the Company may terminate its obligations
under this Indenture (except the Company's obligations under Sections 7.07 and
8.03) if, under terms satisfactory to the Trustee: (a) the Senior Notes have
either become due and payable or are by their terms due and payable within one
year (or scheduled for redemption within one year); and (b) the Company
irrevocably deposits in trust with the Trustee money or United States Government
Obligations (defined below in this Section 8.01), or a combination thereof,
sufficient, without consideration of the reinvestment of interest in the opinion
of the chief financial officer of the Company expressed in a written certificate
delivered to the Trustee, to pay principal and interest on the Senior Notes to
maturity or upon redemption, as the case may be.  The Company may make the
deposit only during the one year period.

     However, the Company's obligations in Sections 2.03, 2.04, 2.05, 2.06,
2.07, 4.01, 4.04, 7.07, 7.08, 8.03 and 8.04 shall survive until the Senior Notes
are no longer outstanding.  Thereafter, only the Company's obligations in
Sections 7.07 and 8.03 shall survive.

     After a deposit made pursuant to this Section 8.01, the Trustee upon
request of the Company shall acknowledge in writing the discharge of the
Company's obligations under this Indenture except for those surviving
obligations specified above.

                                       54
<PAGE>
 
     In addition, the Company may elect to have either clause (ii) or clause
(iii) below be applied to the outstanding Senior Notes upon compliance with the
conditions set forth in clause (iv) below.

     (ii) Upon the Company's exercise under the last sentence of paragraph (i)
above of the option applicable to this paragraph (ii), the Company shall be
deemed to have been released and discharged from its obligations with respect to
the outstanding Senior Notes on the date the conditions set forth below are
satisfied ("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 Senior Notes, which shall thereafter be deemed to
be "outstanding" only for the purpose of the Sections of and matters under this
Indenture referred to in subclauses (A), (B), (C) and (D) of this clause (ii),
and to have satisfied all its other obligations under such Senior Notes and this
Indenture insofar as such Senior Notes are concerned (and the Trustee, at the
expense of the Company, shall execute proper instruments acknowledging the
same), except for the following, which shall survive until otherwise terminated
or discharged hereunder: (A) the rights of holders of outstanding Senior Notes
to receive solely from the trust fund described in clause (iv) below and as more
fully set forth in such clause, payments in respect of the principal of, and
premium, if any, and interest on such Senior Notes when such payments are due,
(B) the Company's obligations with respect to such Senior Notes when such
payments are due, (C) the Company's obligations with respect to such Senior
Notes under Sections 2.03, 2.05, 2.06, 2.07 and 4.04, and, with respect to the
Trustee, under Section 7.07, (D) the rights, powers, trusts, duties and
immunities of the Trustee hereunder and (E) this Section 8.01 and Sections 8.03
and 8.04.  Subject to compliance with this Section 8.01, the Company may
exercise its option under this clause (ii) notwithstanding the prior exercise of
its option under paragraph (iii) below with respect to the Senior Notes.

     (iii) Upon the Company's exercise under the last sentence of clause (i) of
the option applicable to this clause (iii), the Company shall be released and
discharged from its obligations under any covenant contained in Article 4
(except for Sections 4.01 and 4.04) and Article 5 with respect to the
outstanding Senior Notes on and after the date the conditions set forth below
are satisfied ("covenant defeasance"), and the Senior Notes shall thereafter be
deemed to be not "outstanding" for the purpose of any direction, waiver, consent
or declaration or act of holders of Senior Notes (and the consequences of any
thereof) in connection with such covenants, but shall continue to be deemed
"outstanding" for all other purposes hereunder.  For this purpose, such covenant
defeasance means that, with respect to the outstanding Senior 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 6.01 but, except as specified above, the
remainder of this Indenture (including without limitation obligations set forth
in Sections 8.03 and 8.04 hereof) and such Senior Notes shall be unaffected
thereby.

                                       55
<PAGE>
 
     (iv) The following shall be the conditions to the application of either
clause (ii) or (iii) above to the outstanding Senior Notes:

          (a) the Company has irrevocably deposited in trust with the Trustee
     or, at the option of the Trustee, with a trustee, satisfactory to the
     Trustee and the Company, under terms of an irrevocable trust agreement in
     form and substance satisfactory to the Trustee, cash in United States
     dollars, United States Government Obligations, or a combination thereof,
     sufficient, without consideration of the reinvestment of interest, in the
     opinion of the chief financial officer of the Company expressed in a
     written certificate delivered to the Trustee, to pay at maturity principal
     and interest on the Senior Notes; provided that (i) the trustee of the
     irrevocable trust shall have been irrevocably instructed to pay such money
     or the proceeds of such United States Government Obligations to the Trustee
     and (ii) the Trustee shall have been irrevocably instructed to apply such
     money or the proceeds of such United States Government Obligations to the
     payment of said principal and interest with respect to the Senior Notes;

          (b) in the case of an election under clause (ii) above, the Company
     shall have delivered to the Trustee an Opinion of Counsel from nationally
     recognized counsel reasonably acceptable to the Trustee stating that (x)
     the Company has received from, or there has been published by, the Internal
     Revenue Service a ruling or (y) since the date of this Indenture, there has
     been a change in the applicable federal income tax law, in either case to
     the effect that the holders of the outstanding Senior 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 amount and in the same manner and at the same time as would have been
     the case if such legal defeasance had not occurred;

          (c) in the case of an election under clause (iii) above, the Company
     shall have delivered to the Trustee an Opinion of Counsel from nationally
     recognized counsel reasonably acceptable to the Trustee (i) to the effect
     that the holders of the outstanding Senior 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 amount and
     in the same manner and at the same time as would have been the case if such
     covenant defeasance had not occurred or (ii) that the Company has received
     from, or there has been published by, the Internal Revenue Service a ruling
     to the foregoing effect.

          (d) no Default or Event of Default shall have occurred and be
     continuing on the date of such deposit;

          (e) such legal defeasance or covenant defeasance shall not result in a
     breach or violation of, or constitute a Default or Event of Default under
     any material agreement or instrument to which the Company or any of its
     subsidiaries is bound;

                                       56
<PAGE>
 
          (f) The Company shall deliver to the Trustee an Opinion of Counsel to
     the effect that after the 91st day following the deposit, the trust funds
     will not be subject to the effect of any applicable bankruptcy, insolvency,
     reorganization or similar laws affecting creditors' rights generally;

          (g) 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 over the other creditors of the Company
     with the intent of defeating, hindering, delaying or defrauding creditors
     of the Company or others; and

          (h) the Company has delivered to the Trustee an Officers' Certificate
     and an Opinion of Counsel stating that all conditions precedent provided
     for relating to the legal defeasance under clause (ii) above or the
     covenant defeasance under clause (iii) above, as the case may be, have been
     complied with.

     After such irrevocable deposit made pursuant to this Section 8.01 (and
satisfaction of the other conditions set forth herein), the Trustee upon request
shall acknowledge in writing the discharge of the Company's obligations under
this Indenture except for those surviving obligations specified above.

     As used herein, "United States Government Obligations" means obligations
for which the full faith and credit of the United States of America is pledged
and which are not callable at the issuer's option.

SECTION 8.02   Application of Trust Money.
               -------------------------- 

     The Trustee shall hold in trust money or United States Government
Obligations deposited with it pursuant to Section 8.01.  It shall apply the
deposited money and the money from United States Government Obligations through
the Paying Agent and in accordance with this Indenture to the payment of
principal and interest on the Senior Notes.

SECTION 8.03   Repayment to Company.
               -------------------- 

     The Trustee and the Paying Agent shall promptly pay to the Company upon
request any excess money or securities held by them at any time.

     The Trustee and the Paying Agent shall pay to the Company upon request any
money held by them for the payment of principal or interest that remains
unclaimed for two years after the date upon which such payment shall have become
due; provided, however, that the Company shall have first caused notice of such
payment to the Company to be mailed to each holder entitled thereto no less than
30 days prior to such payment.  After payment to the Company, holders entitled
to the money must look to the Company for payment as general creditors unless an
applicable abandoned property law designates another person and all liability of
the Trustee and such Paying Agent with respect to such money shall cease.

                                       57
<PAGE>
 
SECTION 8.04   Reinstatement.
               ------------- 

     If the Trustee or Paying Agent is unable to apply any money in accordance
with Section 8.02 by reason of any order or judgment of any court or
governmental authority enjoining, restraining or otherwise prohibiting such
application, the Company's obligations under this Indenture and the Senior Notes
shall be revived and reinstated as though no deposit had occurred pursuant to
Section 8.01 until such time as the Trustee or Paying Agent is permitted to
apply all such money in accordance with Section 8.02; provided, however, that if
the Company makes any payment of interest on or principal of any Senior Note
following the reinstatement of its obligations, the Company shall be subrogated
to the rights of the holders of such Senior Notes to receive such payment from
the money held by the Trustee or Paying Agent.


                                   ARTICLE 9

                                   Amendments

SECTION 9.01   Without the Consent of Holders.
               ------------------------------ 

     The Company and the Trustee may amend or modify this Indenture (including
the terms and conditions of the Senior Notes) without notice to or the consent
of any holder of Senior Notes for the purpose of:

          (a) adding to the covenants of the Company for the benefit of the
     holders of Senior Notes;

          (b) surrendering any right or power conferred upon the Company;

          (c) evidencing the successor of another corporation to the Company and
     the assumption of the Company thereunder and in the Senior Notes as
     permitted herein;

          (d) curing any ambiguity, or correcting or supplementing any defective
     provision contained herein or making any changes in any other provisions of
     this Indenture which the Company and the Trustee deem necessary or
     desirable and which, in either case, will not adversely affect the
     interests of the holders of Senior Notes.

SECTION 9.02   With the Consent of Holders.
               --------------------------- 

          Subject to Section 6.07, the Company and the Trustee may amend this
     Indenture or the Senior Notes with the written consent of the holders of
     not less than a majority in aggregate principal amount of the then
     outstanding Senior Notes.

                                       58
<PAGE>
 
          Subject to Sections 6.04 and 6.07, the holders of a majority in
     principal amount of the Senior Notes then outstanding may also waive
     compliance in a particular instance by the Company with any provision of
     this Indenture or the Senior Notes.

          However, without the consent of each holder of a Senior Note affected,
     an amendment or waiver under this Section may not:

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

          (b) reduce the rate of or extend the time for payment of, interest,
     including defaulted interest, on any Senior Note;

          (c) reduce the principal of or premium on or change the fixed maturity
     of any Senior Note or alter the redemption provisions with respect thereto;

          (d) make the principal of or premium, if any, or interest on, any
     Senior Note payable in money other than as provided for in this Indenture
     and the Senior Note;

          (e) waive a continuing default in the payment of the principal of or
     premium, if any, interest on, or redemption or repurchase payment with
     respect to, any Senior Note, including, without limitation, a continuing
     default to make payment when required upon a Change of Control or after an
     Asset Sale Offer Trigger Date;

          (f) after the Company's obligation to purchase the Senior Notes arises
     hereunder, to then amend, modify or change the obligation of the Company to
     make or consummate a Change of Control Offer in the event of a Change of
     Control or an Asset Sale Offer in the event of an Asset Sale Offer Trigger
     Date or waive any default in the performance thereof or modify any of the
     provisions or definitions with respect to any such offers; or

          (g) make any change in provisions relating to waivers of defaults, the
     abilities of holders of Senior Notes to enforce their rights hereunder or
     the provisions of clauses (a) through (g) of this Section 9.02.

     To secure a consent of the holders under this Section, it shall not be
necessary for such holders 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 or waiver under this Section becomes effective, the
Company shall mail to holders of Senior Notes a notice briefly describing the
amendment or waiver.

                                       59
<PAGE>
 
SECTION 9.03   Compliance with the Trust Indenture Act.
               --------------------------------------- 

     Every amendment to this Indenture or the Senior Notes shall be set forth in
a supplemental indenture that complies with the TIA as then in effect.

SECTION 9.04   Revocation and Effect of Consents.
               --------------------------------- 

     Until an amendment or waiver becomes effective, a consent to it by a holder
of a Senior Note is a continuing consent by the holder and every subsequent
holder of a Senior Note or portion of a Senior Note that evidences the same debt
as the consenting holder's Senior Note, even if notation of the consent is not
made on any Senior Note.  However, any such holder or subsequent holder may
revoke the consent as to his or her Senior Note or portion of a Senior Note if
the Trustee receives the notice of revocation before the date on which the
Trustee receives an Officers' Certificate certifying that the holders of the
requisite principal amount of Senior Notes have consented to the amendment or
waiver.

     The Company may, but shall not obligated to, fix a record date for the
purpose of determining the holders entitled to consent to any amendment or
waiver.  If a record date is fixed, then notwithstanding the provisions 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 to 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 unless consents from holders of the principal amount of Senior
Notes required hereunder for such amendment or waiver to be effective shall have
also been given and not revoked within such 90-day period.

     After an amendment or waiver becomes effective it shall bind every holder,
unless it is of the type described in any of clauses (a) through (g) of Section
9.02.  In such case, the amendment or waiver shall bind each holder of a Senior
Note who has consented to it.

SECTION 9.05   Notation on or Exchange of Senior Notes.
               --------------------------------------- 

     Senior Notes authenticated and delivered after the execution of any
supplemental indenture pursuant to this Article 9 may, and shall if required by
the Trustee, bear a notation in the form approved by the Trustee as to any
matter provided for in such supplemental indenture.  If the Company shall so
determine, new Senior Notes so modified as to conform, in the opinion of the
Company and the Trustee, to any such supplemental indenture may be prepared and
executed by the Company and authenticated and delivered by the Trustee in

                         11 5/8% SENIOR NOTE DUE 2003

     1.  INTEREST.  Rohr, Inc., a Delaware corporation (the "Company"), promises
to pay interest on the principal amount of this Senior Note at the rate per
annum shown above.  The Company will pay interest semiannually on May 15 and
November 15 of each year.  Interest on the Senior Notes will accrue from the
most recent date to which interest has been paid or, if no interest has been
paid, from May 19, 1994.  Interest will be computed on the basis of a 360-day
year of twelve 30-day months.

     2.  METHOD OF PAYMENT.  The Company will pay interest on the Senior Notes
(except defaulted interest) to the person in whose name each Senior Note is
registered at the close of business on the May 1 or November 1 immediately
preceding the relevant interest payment date even though Senior Notes are
cancelled after such record date and on or before the interest payment date.
Holders must surrender Senior Notes to a Paying Agent to collect principal
payments.  The Company will pay principal and interest in money of the United
States that at the time of payment is legal tender for payment of public and
private debts.  However, the Company may pay principal and interest by check
payable in such money, and may mail such check to the holder's registered
address.

     3.  PAYING AGENT AND REGISTRAR.  IBJ Schroder Bank & Trust Company, a New
York banking corporation (together with any successor trustee under the
Indenture referred to below, the "Trustee"), will act as Paying Agent and
Registrar.  The Company may change the Paying Agent, Registrar or co-registrar
without prior notice.  Subject to certain limitations in the Indenture, the
Company or any of its Subsidiaries may act in any such capacity.

     4.  INDENTURE.  The Company issued the Senior Notes under an  Indenture
dated as of May 15, 1994 (the "Indenture") between the Company and the Trustee.
The terms of the Senior Notes include those stated in the Indenture and those
made part of the Indenture by reference to the Trust Indenture Act of 1939 (15
U.S. Code (S)(S) 77aaa-77bbbb) as in effect on the date of the Indenture.  The
Senior Notes are subject to, and qualified by, all such terms, certain of which
are summarized hereon, and holders are referred to the Indenture and such Act
for a statement of such terms.  The Senior Notes are unsecured general
obligations of the Company limited to $100,000,000 in aggregate principal
amount.  Capitalized terms not defined below have the same meaning as is given
to them in the Indenture.

     5.  OPTIONAL REDEMPTION.  The Company may redeem the Senior Notes, in whole
or in part, prior to maturity at any time on or after May 15, 1999 at the
redemption prices (expressed in percentages of principal amount) set forth below
plus accrued interest to the date fixed for redemption, if redeemed during the
12-month period beginning on May 15 of each year starting with the year
indicated below.

</TABLE>

     6. NOTICE OF REDEMPTION. Notice of redemption will be mailed at least 30
days but not more than 60 days before the date fixed for redemption to each
holder of Senior Notes to be redeemed at his or her registered address. Senior
Notes in denominations larger than $1,000 may be redeemed in part but only in
whole multiples of $1,000. In the event of a redemption of less than all of the
Senior Notes, the Senior Notes will be chosen for redemption by the Trustee by
lot or pro rata or, if required, in compliance with the requirements of the
principal national securities exchange, if any, on which the Senior Notes are
listed. On and after the redemption date interest ceases to accrue on Senior
Notes or portions of them called for redemption (unless the Company defaults in
the payment of the redemption price). If this Senior Note is redeemed subsequent
to a record date with respect to any interest payment date specified above and
on or prior to such interest payment date, then any accrued interest will be
paid to the person in whose name this Senior Note is registered at the close of
business on such record date.

     7. CHANGE OF CONTROL. Upon a Change of Control, the Company shall make a
Change of Control Offer to purchase all outstanding securities at a price equal
to 101% of the aggregate principal amount of the Senior Notes, plus accrued and
unpaid interest to the date of purchase, such offer to be made as provided in
the Indenture. To accept the Change of Control Offer, the holder hereof must
comply with the terms thereof, including surrendering this Senior Note, with the
"Option of Holder to Elect Purchase" portion hereof completed, to the Company, a
depositary, if appointed by the Company, or a Paying Agent, at the address
specified in the notice of the Change of Control Offer mailed to holders as
provided in the Indenture, prior to termination of the Change of Control Offer.

     8. DENOMINATIONS, TRANSFER, EXCHANGE. The Senior Notes are in registered
form without coupons in denominations of $1,000 and integral multiples of
$1,000. The transfer of Senior Notes may be registered and Senior Notes may be
exchanged as provided in the Indenture. As a condition of transfer, the
Registrar 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 Registrar
need not exchange or register the transfer of any Senior Note or portion of a
Senior Note selected for redemption. Also, it need not exchange or register the
transfer of any Senior Notes for a period of 15 days before a selection of
Senior Notes to be redeemed.

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

                                      A-3
<PAGE>
 
     10. AMENDMENTS AND WAIVERS. Subject to certain exceptions, the Indenture or
the Senior Notes may be amended with the consent of the holders of at least a
majority in principal amount of the then outstanding Senior Notes and any
existing default may be waived with the consent of the holders of a majority in
principal amount of the then outstanding Senior Notes. Without the consent of
any holder, the Indenture or the Senior Notes may be amended to: add to the
covenants of the Company for the benefit of the holders; surrender any right or
power conferred upon the Company; evidence the succession of another person to
the Company and the assumption by such successor of the covenants and
obligations of the Company thereunder and in the Senior Notes as permitted in
the Indenture; and cure any ambiguity or correct or supplement any defective
provision herein or make any changes in any other provisions of the Indenture
which the Company and the Trustee deem necessary or desirable and which in
either case will not adversely affect the interest of the holders of the Senior
Notes.

     11. DEFAULTS AND REMEDIES. An Event of Default is: default for 30 days in
payment of interest on the Senior Notes; default in payment of principal of or
premium if any, on the Senior Notes; failure by the Company for 45 days after
notice to it to comply with any of its other agreements in the Indenture or the
Senior Notes (except that with respect to certain other covenants, such defaults
shall be Events of Default with such notice but without such passage of time);
certain defaults under and accelerations prior to maturity of certain
indebtedness; certain final judgments which remain undischarged; and certain
events of bankruptcy or insolvency. If an Event of Default occurs and is
continuing, the Trustee or the holders of at least 25% in principal amount of
the then outstanding Senior Notes may declare all the Senior Notes to be due and
payable immediately, except that in the case of an Event of Default arising from
certain events of bankruptcy or insolvency, all outstanding Senior Notes become
due and payable without further action or notice. Holders may not enforce the
Indenture or the Senior Notes except as provided in the Indenture. The Trustee
may require indemnity satisfactory to it before it enforces the Indenture or the
Senior Notes. Subject to certain limitations, holders of a majority in principal
amount of the then outstanding Senior Notes may direct the Trustee in its
exercise of any trust or power. The Trustee may withhold from holders notice of
any continuing default (except a default in payment of principal or interest) if
it determines that withholding notice is in their interests. The Company must
furnish quarterly compliance certificates to the Trustee.

     12. TRUSTEE DEALINGS WITH THE COMPANY. The Trustee or any of its
Affiliates, in their individual or any other capacities, may make or continue
loans to or guaranteed by, 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 Trustee.

     13. NO RECOURSE AGAINST OTHERS. No director, officer, employee or
stockholder, as such, of the Company shall have any liability for any
obligations of the Company under the Senior Notes 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 Senior Note waives and releases all such
liability. The waiver and release are part of the consideration for the Senior
Notes.

                       The Convertible Subordinated Notes

SECTION 2.01   Form and Dating.
               --------------- 

     The Convertible Subordinated Notes and the Trustee's certificate of
authentication relating thereto shall be substantially in the form set forth in
Exhibit A, which is part of this

                                       13
<PAGE>
 
Indenture, with such appropriate insertions, omissions, substitutions and other
variations as are required or permitted by this Indenture. The Convertible
Subordinated Notes may have notations, legends or endorsements required by law,
stock exchange rule or usage. The Company shall approve the form of the
Convertible Subordinated Notes and any notation, legend or endorsement on them.
Each Convertible Subordinated Note shall be dated the date of its
authentication.

     The terms and provisions contained in the Convertible Subordinated Notes
shall constitute, and are hereby expressly made, a part of this Indenture and,
to the extent applicable, 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.

SECTION 2.02  Execution and Authentication.
              ---------------------------- 

     Two Officers shall sign the Convertible Subordinated Notes for the Company
by manual or facsimile signature. The Company's seal shall be reproduced on the
Convertible Subordinated Notes.

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

     A Convertible Subordinated Note shall not be valid until authenticated by
the manual signature of the Trustee. The signature shall be conclusive evidence
that the Convertible Subordinated Note has been authenticated under this
Indenture.

     Upon a written order of the Company signed by an Officer of the Company,
the Trustee shall authenticate Convertible Subordinated Notes for original issue
up to an aggregate principal amount of $50,000,000 (plus up to $7,500,000
aggregate principal amount of Convertible Subordinated Notes that may be sold by
the Company pursuant to the over-allotment option granted pursuant to the
Underwriting Agreement, dated as of May 12, 1994, between the Company and
Salomon Brothers Inc). The aggregate principal amount of Convertible
Subordinated Notes outstanding at any time may not exceed that amount except as
provided in Section 2.07.

     The Convertible Subordinated Notes shall be issuable only in registered
form without coupons and only in denominations of $1,000 or any integral
multiple thereof.

     The Trustee may appoint an authenticating agent acceptable to the Company
to authenticate Convertible Subordinated Notes. An authenticating agent may
authenticate Convertible Subordinated 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 same right as an Agent
to deal with the Company or an Affiliate of the Company.

                                       14

SECTION 2.03  Registrar and Paying Agent.
              -------------------------- 

     The Company shall maintain or cause to be maintained in the Borough of
Manhattan, New York, New York (the "New York Office"), and in such other
locations as it shall determine, an office or agency: (i) where securities may
be presented for registration of transfer or for exchange ("Registrar"); (ii)
where Convertible Subordinated Notes may be presented for payment ("Paying
Agent"); and (iii) where notices and demand to or upon the Company in respect of
Convertible Subordinated Notes and this Indenture may be served by the holders
of the Convertible Subordinated Notes. The Registrar shall keep a register of
the Convertible Subordinated Notes and of their transfer and exchange. The
Company may appoint one or more co-registrars and one or more additional paying
agents. The term "Paying Agent" includes any additional paying agent. The
Company may change any Paying Agent, Registrar or co-registrar without prior
notice. The Company shall notify the Trustee of the name and address of any
Agent not a party to this Indenture and shall enter into an appropriate agency
agreement with any Registrar, Paying Agent or co-registrar not a party to this
Indenture. The agreement shall implement the provisions of this Indenture that
relate to such Agent. The Company or any of its subsidiaries may act as Paying
Agent, Registrar or co-registrar, except that for purposes of Articles 3 and 8
and Sections 4.05 and 4.08, neither the Company nor any of its subsidiaries
shall act as Paying Agent. If the Company fails to appoint or maintain another
entity as Registrar or Paying Agent, the Trustee shall act as such, and the
Trustee shall initially act as such. The Trustee shall cause the New York Office
to be maintained as long as it acts as Registrar or Paying Agent.

SECTION 2.04  Paying Agent To Hold Money in Trust.
              ----------------------------------- 

     The Company shall require each Paying Agent (other than the Trustee, who
hereby so agrees), to agree in writing that the Paying Agent will hold in trust
for the benefit of holders of the Convertible Subordinated Notes or the Trustee
all money held by the Paying Agent for the payment of principal or interest on
the Convertible Subordinated Notes, and will notify the Trustee of any default
by the Company in respect of making any such payment. While any such default
continues, the Trustee may require a Paying Agent to 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 over to the Trustee, the Paying Agent
(if other than the Company or a subsidiary of the Company) shall have no further
liability for the money. If the Company or a subsidiary of the Company acts as
Paying Agent, it shall segregate and hold in a separate trust fund for the
benefit of the holders of the Convertible Subordinated Notes all money held by
it as Paying Agent.

SECTION 2.05  Holder Lists.
              ------------ 

     The Trustee shall preserve in as current a form as is reasonably
practicable the most recent list available to it of the names and addresses of
holders of Convertible Subordinated Notes. If the Trustee is not the Registrar,
the Company shall furnish to the Trustee at least seven days before each
interest payment date and at such other times as the Trustee may request

                                       15
<PAGE>
 
in writing a list in such form and as of such date as the Trustee may reasonably
require of the names and addresses of holders of Convertible Subordinated Notes.

SECTION 2.06  Transfer and Exchange.
              --------------------- 

     Where Convertible Subordinated Notes are presented to the Registrar or a 
co-registrar with a request to register a transfer or to exchange them for an
equal principal amount of Convertible Subordinated Notes for other
denominations, the Registrar shall register the transfer or make the exchange if
its requirements for such transactions are met. To permit registrations of
transfers and exchanges, the Company shall issue and the Trustee shall
authenticate Convertible Subordinated Notes at the Registrar's request. No
service charge shall be made for any registration of transfer or exchange
(except as otherwise expressly permitted herein), but the Company may require
payment of a sum sufficient to cover any transfer tax or similar governmental
charge payable upon exchanges pursuant to Sections 2.10, 3.06 or 9.05.

     The Company shall not be required (i) to issue, register the transfer of or
exchange Convertible Subordinated Notes during a period beginning at the opening
of business 15 days before the day of any selection of Convertible Subordinated
Notes for redemption under Section 3.02 and ending at the close of business on
the day of selection, or (ii) to register the transfer or exchange of any
Convertible Subordinated Note so selected for redemption in whole or in part,
except the unredeemed portion of any Convertible Subordinated Note being
redeemed in part.

SECTION 2.07  Replacement Convertible Subordinated Notes.
              ------------------------------------------ 

     If the holder of a Convertible Subordinated Note claims that the
Convertible Subordinated Note has been lost, destroyed or wrongfully taken, the
Company shall issue and the Trustee shall authenticate a replacement Convertible
Subordinated Note if the Trustee's requirements are met. If required by the
Trustee or the Company as a condition of receiving a replacement Convertible
Subordinated Note, the holder of a Convertible Subordinated Note must provide an
indemnity bond sufficient, in the judgment of both the Company and the Trustee,
to fully protect the Company, the Trustee, any Agent and any authenticating
agent from any loss which any of them may suffer if the Convertible Subordinated
Note is replaced. The Company and the Trustee may charge the relevant holder for
their expenses in replacing any Convertible Subordinated Note.

     Every replacement Convertible Subordinated Note is an additional obligation
of the Company.

SECTION 2.08  Outstanding Convertible Subordinated Notes.
              ------------------------------------------ 

     The Convertible Subordinated Notes outstanding at any time are all the
Convertible Subordinated Notes properly authenticated by the Trustee except for
those cancelled by the Trustee, those delivered to it for cancellation, and
those described in this Section as not outstanding.

                                       16
<PAGE>
 
     If a Convertible Subordinated Note is replaced pursuant to Section 2.07, it
ceases to be outstanding unless the Trustee receives proof satisfactory to it
that the replaced Convertible Subordinated Note is held by a bona fide
purchaser.

     If Convertible Subordinated Notes are considered paid under Section 4.01,
they cease to be outstanding and interest on them ceases to accrue.

     A Convertible Subordinated Note does not cease to be outstanding because
the Company or an Affiliate of the Company holds the Convertible Subordinated
Note.

SECTION 2.09  When Treasury Convertible Subordinated Notes Disregarded.
              -------------------------------------------------------- 

     In determining whether the holders of the required principal amount of
Convertible Subordinated Notes have concurred in any direction, waiver or
consent, Convertible Subordinated Notes owned by the Company or an Affiliate of
the Company shall be considered as though they are 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 Convertible Subordinated
Notes which the Trustee knows are so owned shall be so disregarded.

SECTION 2.10  Temporary Convertible Subordinated Notes.
              ---------------------------------------- 

     Until definitive Convertible Subordinated Notes are ready for delivery, the
Company may prepare and the Trustee shall authenticate temporary Convertible
Subordinated Notes. Temporary Convertible Subordinated Notes shall be
substantially in the form of definitive Convertible Subordinated Notes but may
have variations that the Company considers appropriate for temporary Convertible
Subordinated Notes. If temporary Convertible Subordinated Notes are issued, the
Company will cause definitive Convertible Subordinated Notes to be prepared
without unreasonable delay. After the preparation of definitive Convertible
Subordinated Notes, the temporary Convertible Subordinated Notes shall be
exchangeable for definitive Convertible Subordinated Notes upon surrender of the
temporary Convertible Subordinated Notes at any office or agency of the Company
designated pursuant to Section 2.03 without charge to the holder of the
Convertible Subordinated Note. Upon surrender for cancellation of any one or
more temporary Convertible Subordinated Notes the Company shall execute and the
Trustee shall authenticate and deliver in exchange therefor a like principal
amount of definitive Convertible Subordinated Notes of authorized denominations.
Until so exchanged, the temporary Convertible Subordinated Notes shall in all
respects be entitled to the same benefits under this Indenture as definitive
Convertible Subordinated Notes.

SECTION 2.11  Cancellation.
              ------------ 

     The Company at any time may deliver Convertible Subordinated Notes to the
Trustee for cancellation. The Registrar and Paying Agent shall forward to the
Trustee any Convertible Subordinated Notes surrendered to them for registration
of transfer, exchange or payment. The Trustee and no one else shall cancel
Convertible Subordinated Notes surrendered for registration

                                       17
<PAGE>
 
of transfer, exchange, payment, replacement or cancellation and shall dispose of
cancelled Convertible Subordinated Notes as the Company directs, provided that
the Trustee shall not be required to destroy such Convertible Subordinated
Notes. The Company may not issue new Convertible Subordinated Notes to replace
Convertible Subordinated Notes that it has paid or that have been delivered to
the Trustee for cancellation.

SECTION 2.12  Defaulted Interest.
              ------------------ 

     If the Company fails to make a payment of interest on the Convertible
Subordinated Notes, it shall pay such defaulted interest plus, to the extent
lawful, any interest payable on the defaulted interest. It may pay such
defaulted interest, plus any such interest payable on it, to the persons who are
holders of Convertible Subordinated Notes on a subsequent special record date.
The Company shall fix any such record date and payment date. At least 15 days
before any such record date, the Company shall mail to holders of the
Convertible Subordinated Notes a notice that states the record date, payment
date and amount of such interest to be paid.

SECTION 2.13  CUSIP Number.
              ------------ 

     The Company in issuing the Convertible Subordinated Notes may use a "CUSIP"
number, and if so, such CUSIP number shall be included in notices of redemption
or exchange as a convenience to holders of Convertible Subordinated Notes;
provided, however, that any such notice may state that no representation is made
as to the correctness or accuracy of the CUSIP number printed in the notice or
on the Convertible Subordinated Notes and that reliance may be placed only on
the other identification numbers printed on the Convertible Subordinated Notes.
The Company will promptly notify the Trustee of any change in the CUSIP number.

SECTION 3.01   Notices to Trustee.
               ------------------ 

     If the Company elects to redeem Convertible Subordinated Notes pursuant to
the optional redemption provisions of paragraph 5 of the Convertible
Subordinated Notes, it shall notify the Trustee of the redemption date and the
principal amount of Convertible Subordinated Notes to be redeemed. The
redemption price shall be the amount determined pursuant to paragraph 5 of the
Convertible Subordinated Notes.

     The Company shall give each notice provided for in this Section at least 50
days before the redemption date (unless a shorter notice period shall be
satisfactory to the Trustee).

SECTION 3.02  Selection of Convertible Subordinated Notes To Be Redeemed.
              ---------------------------------------------------------- 

     If less than all the Convertible Subordinated Notes are to be redeemed, the
Trustee shall select the Convertible Subordinated Notes to be redeemed by lot or
pro rata or by a method that complies with the requirements of any exchange on
which the Convertible Subordinated Notes are listed that the Trustee considers
fair and appropriate. The Trustee shall make the selection not more than 75 days
and not less than 30 days before the redemption date from Convertible
Subordinated Notes outstanding not previously called for redemption. The Trustee
may select for redemption portions of the principal of Convertible Subordinated
Notes that have a denomination larger than $1,000. Convertible Subordinated
Notes and portions thereof will be redeemed in the amount of $1,000 or integral
multiples of $1,000. Provisions of this Indenture that apply to Convertible
Subordinated Notes called for redemption also apply to portions of Convertible
Subordinated Notes called for redemption. The Trustee will make the selection of
Convertible Subordinated Notes outstanding and not previously called for
redemption. The Trustee shall notify the Company promptly of the Convertible
Subordinated Notes or portions of Convertible Subordinated Notes to be called
for redemption.

SECTION 3.03  Notice of Redemption.
              -------------------- 

     At least 30 days but not more than 60 days before a redemption date, the
Company shall mail a notice of redemption to each holder whose Convertible
Subordinated Notes are to be redeemed.

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

          (1) the redemption date;

          (2) the redemption price;

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

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

          (5) that interest on Convertible Subordinated Notes called for
     redemption and for which funds have been set apart for payment, ceases to
     accrue on and after the redemption date (unless the Company defaults in the
     payment of the redemption price);

                                       19
<PAGE>
 
          (6) the paragraph of the Convertible Subordinated Notes pursuant to

          (7) the aggregate principal amount of Convertible Subordinated Notes
     that are being redeemed;

     that the disclaimer permitted by Section 2.13 may be made);

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

          (10) that Convertible Subordinated Notes called for redemption may be
     converted at any time prior to the close of business on the redemption date
     and if not converted prior to the close of business on such date, the right
     of conversion will be lost.

     At the Company's request, the Trustee shall give notice of redemption in
the Company's name and at its expense.

SECTION 3.04   Effect of Notice of Redemption.
               ------------------------------ 

     Once notice of redemption is mailed, Convertible Subordinated Notes called
for redemption become due and payable on the redemption date at the price set
forth in the Convertible Subordinated Note.

SECTION 3.05   Deposit of Redemption Price.
               --------------------------- 

     On or before the redemption date, the Company shall deposit with the
Trustee or with the Paying Agent money in immediately available funds sufficient
to pay the redemption price of and accrued interest on all Convertible
Subordinated Notes to be redeemed on that date.  The Trustee or the Paying Agent
shall return to the Company any money not required for that purpose.

SECTION 3.06   Convertible Subordinated Notes Redeemed in Part.
               ----------------------------------------------- 

     Upon surrender of a Convertible Subordinated Note that is redeemed in part,

<PAGE>
 
SECTION 4.01   Payment of Convertible Subordinated Notes.
               ----------------------------------------- 

     The Company shall pay the principal of and interest on the Convertible
Subordinated Notes on the dates and in the manner provided in the Convertible
Subordinated Notes.  Principal and interest shall be considered paid on the date
due if the Trustee or Paying Agent (other than the Company or a subsidiary of
the Company) holds as of 1:00 P.M.  Eastern Time on that date immediately
available funds designated for and sufficient to pay all principal and interest
then due, provided, however, that money held by the Agent for the benefit of
holders of Senior Indebtedness pursuant to the provisions of Article 11 hereof
or the payment of which to the holders of the Convertible Subordinated Notes is
prohibited by Article 11 shall not be considered to be designated for the
payment of any principle of or interest on the Convertible Subordinated Notes
within the meaning of this Section 4.01.

     To the extent lawful, the Company shall pay interest (including post-
petition interest in any proceeding under any Bankruptcy Law) on (i) overdue
principal, at the rate borne by Convertible Subordinated Notes, compounded
semiannually; and (ii) overdue installments of interest (without regard to any
applicable grace period) at the same rate, compounded semiannually.

SECTION 4.02   Commission Reports.
               ------------------ 

     So long as any Convertible Subordinated Note is outstanding, the Company
shall file with the Commission and, within 15 days after it files them with the
Commission, file with the Trustee and thereafter mail promptly or cause the
Trustee to mail promptly to the holders of Convertible Subordinated Notes at
their addresses as set forth in the register of the Convertible Subordinated
Notes copies of the annual reports and of the information, documents and other
reports which the Company is required to file with the Commission pursuant to
Section 13 or 15(d) of the Exchange Act or which the Company would be required
to file with the Commission if the Company then had a class of securities
registered under the Exchange Act.  In addition, the Company shall cause its
annual report to stockholders and any quarterly or other financial reports
furnished to its stockholders generally to be filed with the Trustee, no later
than the date such materials are mailed or made available to the Company's
stockholders, and thereafter mailed promptly to the holders of Convertible
Subordinated Notes at their addresses as set forth in the register of
Convertible Subordinated Notes.

SECTION 4.03   Compliance Certificate.
               ---------------------- 

     The Company shall deliver to the Trustee, within 60 days after the end of
the first three fiscal quarters and within 120 days after the end of each fiscal
year of the Company, an Officers' Certificate stating that a review of the
activities of the Company and its subsidiaries during the preceding fiscal
period has been made under the supervision of the signing Officers with a view
to determining whether the Company has fully performed its obligations under
this Indenture and further stating, as to each such Officer signing such
certificate, that to the best of his or her knowledge the Company has kept,
observed, performed and fulfilled each and every

                                       21
<PAGE>
 
covenant contained in this Indenture and is not in default in the performance or
observance of any of the terms and conditions hereof (or, if any Default or
Event of Default shall have occurred, describing all such Defaults or Events of
Default of which he or she may have knowledge) and that to the best of his or
her knowledge no event has occurred and remains in existence by reason of which
payments on account of the principal of or interest on the Convertible
Subordinated Notes are prohibited.

     The Company shall, so long as any of the Convertible Subordinated Notes are
outstanding, deliver to the Trustee, forthwith upon becoming aware of any
Default, Event of Default or default in the performance of any term or condition
in this Indenture, without regard to any period of grace or requirement of
notice provided hereunder, an Officers' Certificate specifying such Default,
Event of Default or default.

SECTION 4.04   Maintenance of Office or Agency.
               ------------------------------- 

     The Company shall maintain or cause to be maintained the office or agency
required under Section 2.03.  The Company shall give prompt written notice to
the Trustee of the location, and any change in the location, of such office or
agency not maintained by the Trustee.

     The Company may also from time to time designate one or more other offices
or agencies where the Convertible Subordinated Notes may be presented or
surrendered for any or all such purposes and may from time to time rescind such
designation; provided, however, that no such designation or rescission shall in
any manner relieve the Company of its obligation to maintain or cause to be
maintained an office or agency in the City of New York for such purpose.

SECTION 4.05   Limitation on Sale of Assets.
               ---------------------------- 

     The Company will not, and will not permit any of its subsidiaries to,
consummate any Asset Sale unless such Asset Sale is for at least Fair Market
Value and at least 80% of the consideration therefrom received by the Company or
such subsidiary is in the form of cash or Cash Equivalents.

     Following any Asset Sale, an amount equal to the Net Cash Proceeds of such
Asset Sale shall be applied by the Company or such subsidiary within 365 days of
the date of the Asset Sale, at its election, to either: (a) the payment of
Senior Indebtedness; provided, however, any Net Cash Proceeds which are applied
to reduce Indebtedness under the Revolving Credit Agreement shall result in a
permanent reduction of the borrowing availability thereunder; (b) make any
Permitted Program Investment or any other investment in capital assets usable in
the Company's or its subsidiaries' lines of business or in an asset or business
in the same line of business as the Company; or (c) a combination of payment and
investment permitted by the foregoing clauses (a) and (b).  On the earlier of
(A) the 366th day after the date of an Asset Sale or (B) such date as the Board
of Directors of the Company or of such subsidiary determines (as

                                       22
<PAGE>
 
evidenced by a written resolution of said Board of Directors) not to apply an
amount equal to the Net Cash Proceeds relating to such Asset Sale as set forth
in the immediately preceding sentence (each of (A) and (B), an "Asset Sale Offer
Trigger Date"), the Company or such subsidiary shall be obligated to apply an
amount equal to aggregate amount of Net Cash Proceeds which have not been
applied on or before such Asset Sale Offer Trigger Date as permitted by the
foregoing clauses (a), (b) and (c) of the immediately preceding sentence (each
an "Asset Sale Offer Amount") to make an offer to purchase for cash (the "Asset
Sale Offer") from all holders of Convertible Subordinated Notes on a pro rata
basis that amount of Convertible Subordinated Notes equal to the Asset Sale
Offer Amount at a price equal to 100% of the principal amount of the Convertible
Subordinated Notes to be repurchased, plus accrued and unpaid interest thereon
to the date of repurchase.  Notwithstanding the foregoing, if an Asset Sale
Offer Amount is less than $10 million, the application of such Asset Sale Offer
Amount to an Asset Sale Offer may be deferred until such time as such Asset Sale
Offer Amount plus the aggregate amount of all Asset Sale Offer Amounts arising
subsequent to such Asset Sale Offer Trigger Date from all Asset Sales by the
Company and its subsidiaries aggregates at least $10 million, at which time the
Company or such subsidiary shall apply all Asset Sale Offer Amounts that have
been so deferred to make an Asset Sale Offer (the first date the aggregate of
all such deferred Asset Sale Offer Amounts is equal to $10 million or more shall
be deemed to be an "Asset Sale Offer Trigger Date").

     In the event of the transfer of substantially all (but not all) of the
property and assets of the Company as an entirety to a Person in a transaction
permitted under Section 5.01, the successor corporation shall be deemed to have
sold the properties and assets of the Company not so transferred for purposes of
this covenant, and shall comply with the provisions of this covenant with
respect to such deemed sale as if it were an Asset Sale.

     Each Asset Sale Offer shall be mailed to the holders of the Convertible
Subordinated Notes at the addresses shown on the register of holders maintained
by the Registrar with a copy to the Trustee and the Paying Agent, within 10 days
following the applicable Asset Sale Offer Trigger Date, and shall comply with
each of the procedures for notice set forth below.  Each Asset Sale Offer shall
remain open until a specified date (the "Asset Sale Offer Termination Date")
which is at least 20 business days from the date such Asset Sale Offer is
mailed.  During the period specified in the Asset Sale Offer, holders of
Convertible Subordinated Notes may elect to tender their Convertible
Subordinated Notes in whole or in part in integral multiples of $1,000 in
exchange for cash.  Payment shall be made by the Company (or applicable
subsidiary) in respect of Convertible Subordinated Notes properly tendered
pursuant to this Section on a specified business day (the "Asset Sale Offer
Payment Date") which shall be no earlier than three business days after the
Asset Sale Offer Termination Date and no later then 60 days after such
applicable Asset Sale Offer Trigger Date.  To the extent holders of Convertible
Subordinated Notes properly tender Convertible Subordinated Notes in an amount
exceeding the Asset Sale Offer Amount, Convertible Subordinated Notes of

     (a), (b) and (c) above) in the performance of, or breach of, any other
     covenant or warranty of the Company set forth in this Indenture or the
     Convertible Subordinated Notes and fails to remedy such default or breach

SECTION 6.02   Acceleration.
               ------------ 

     If an Event of Default (other than an Event of Default specified in clauses
(g) and (h) of Section 6.01) occurs and is continuing, then and in every such
case the Trustee, by written notice to the Company (with a copy to the Bank
Agent, each of the holders of the Company's 9.33% Senior Notes and its 9.35%
Senior Notes and any other Representatives of Designated Senior Indebtedness),
or the holders of at least 25% in aggregate principal amount of the then
outstanding Convertible Subordinated Notes, by written notice to the Company and
the Trustee (with a copy to the Bank Agent, each of the holders of the Company's
9.33% Senior Notes and its 9.35% Senior Notes and any other Representatives of
Designated Senior Indebtedness), may declare the unpaid principal of and accrued
interest on all the Convertible Subordinated Notes to be due and payable,
provided, however that failure to provide a copy of such notice to any party
other than the Company and the Trustee shall have no effect on any such
declaration.  Upon such declaration such principal amount, premium, if any, and
accrued and unpaid interest shall become immediately due and payable,
notwithstanding anything contained in this Indenture or the Convertible
Subordinated Notes to the contrary but subject to the provisions of Article 11
hereof; and provided further, that so long as any Designated Senior Indebtedness
is outstanding, any such declaration shall not be effective until the earlier of
(a) five business days after the delivery of such notice to the Company or (b)
the acceleration of any Designated Senior Indebtedness.  If any Event of Default
with respect to the Company specified in clauses (g) or (h) of Section 6.01
occurs, all unpaid principal of and premium, if any, and accrued and unpaid
interest on the Convertible Subordinated Notes then outstanding shall become
automatically due and payable subject to the provisions of Article 11 hereof,
without any declaration or other act on the part of the Trustee or any holder of
Convertible Subordinated Notes.

     The holders of a majority in principal amount of the then outstanding
Convertible Subordinated Notes by notice to the Trustee may rescind an
acceleration of the Convertible Subordinated Notes and its consequences if all
existing Events of Default (other than nonpayment of principal of or premium, if
any, and interest on the Convertible Subordinated Notes which has become due
solely by virtue of such acceleration) have been cured or waived and if the
rescission would not conflict with any judgment or decree of any court of
competent jurisdiction.  No such rescission shall affect any subsequent Default
or Event of Default or impair any right consequent thereto.

SECTION 6.03   Other Remedies.
               -------------- 

     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 the payment of
principal of or interest on the Convertible Subordinated Notes or to enforce the
performance of any provision of the Convertible Subordinated Notes or this
Indenture.  The Trustee may maintain a proceeding even if it does not possess
any of the Convertible Subordinated Notes or does not produce any of them in the
proceeding.  A delay or omission by the Trustee or any holder of a Convertible
Subordinated Note in exercising any right or remedy accruing upon an Event of
Default shall

                                       32
<PAGE>
 
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 6.04   Waiver of Past Defaults.
               ----------------------- 

     The holders of a majority in aggregate principal amount of the Convertible
Subordinated Notes then outstanding may, on behalf of the holders of all the
Convertible Subordinated Notes waive an existing Default or Event of Default and
its consequences, except a Default or Event of Default in the payment of the
principal of or interest on the Convertible Subordinated Notes (other than the
non-payment of principle of and premium, if any, and interest on the Convertible
Subordinated Notes which has become due solely by virtue of an acceleration
which has been duly rescinded as provided above), or in respect of a covenant or
provision of this Indenture which cannot be modified or amended without the
consent of all holders of convertible Subordinated Notes.  When a Default is
waived, it is cured and stops continuing.  No waiver shall extend to any
subsequent or other Default or impair any right consequent thereon.

SECTION 6.05   Control by Majority.
               ------------------- 

     The holders of a majority in principal amount of the then outstanding
Convertible Subordinated Notes 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, that the Trustee
determines may be unduly prejudicial to the rights of other holders of
Convertible Subordinated Notes or that may involve the Trustee in personal
liability; provided, that the Trustee may take any other action the Trustee
deems proper that is not inconsistent with such directions.

SECTION 6.06   Limitation on Suits.
               ------------------- 

A holder of a Convertible Subordinated Note may not pursue any remedy with
respect to this Indenture or the Convertible Subordinated Notes unless:

          (1) the holder gives to the Trustee notice of a continuing Event of
     Default;

          (2) the holders of at least 25% in principal amount of the then
     outstanding Convertible Subordinated Notes make a request to the Trustee to
     pursue the remedy;

          (3) such holder or holders offer and, if requested, provide to the
     Trustee indemnity satisfactory to the Trustee against any loss, liability
     or expense;

          (4) the Trustee does not comply with the request within 60 days after
     receipt of the request and the offer and, if requested, the provision of
     indemnity; and

                                       33
<PAGE>
 
          (5) during such 60-day period the holders of a majority in principal
     amount of the then outstanding Convertible Subordinated Notes do not give
     the Trustee a direction inconsistent with the request.

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

SECTION 6.07   Rights of Holders To Receive Payment.
               ------------------------------------ 

     Subject to the provisions of Article 11 hereof, notwithstanding any other

Subordinated Note to receive payment of principal and interest on the
Convertible Subordinated Note, on or after the respective due dates expressed in

impaired or affected without the consent of the holder of a Convertible
Subordinated Note.

SECTION 6.08   Collection Suit by Trustee.
               -------------------------- 

     If an Event of Default specified in Section 6.01(a) or (b) occurs and is
continuing, the Trustee may recover judgment in its own name and as trustee of
an express trust against the Company for the whole amount of principal and
interest remaining unpaid on the Convertible Subordinated Notes and interest on
overdue principal and interest and such further amount as shall be sufficient to
cover the costs and, to the extent lawful, expenses of collection, including the
reasonable compensation, expenses, disbursements and advances of the Trustee,
its agents and counsel.

SECTION 6.09   Trustee May File Proofs of Claim.
               -------------------------------- 

     The Trustee may 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 and the
holders of Convertible Subordinated Notes allowed in any judicial proceedings
relative to the Company, its creditors or its property.  Nothing contained
herein shall be deemed to authorize the Trustee to authorize or consent to or
accept or adopt on behalf of any holder of a Convertible Subordinated Note any
plan of reorganization, arrangement, adjustment or composition affecting the
Convertible Subordinated Notes or the rights of any holder thereof, or to
authorize the Trustee to vote in respect of the claim of any holder in any such
proceeding.

     If the Trustee collects any money pursuant to this Article, it shall pay

          First: to the Trustee for amounts due under Section 7.07, including

          Fourth: to the Company.

     Except as otherwise provided in Section 2.12, the Trustee may fix a record
date and payment date for any payment to holders of Convertible Subordinated
Notes.

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, a court in its discretion may require the filing by any party litigant
in the suit, other than the Trustee, 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 pursuant to Section 6.07 or a suit by holders of more than 10% in
principal amount of the then outstanding Convertible Subordinated Notes.


                                   ARTICLE 7

                                  The Trustee

conduct or affecting the liability of or affording protection to the Trustee
shall be subject to the provisions of this Article 7.

SECTION 7.01   Duties of the Trustee.
               --------------------- 

     (a) If an Event of Default known to the Trustee 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 their exercise

of his or her own affairs.

                                       35
<PAGE>
 
     (b) Except during the continuance of an Event of Default known to the
Trustee:

          (1) The duties of the Trustee 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

          (2) 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 they conform to the form required by this Indenture.

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

     Section;

     takes or omits to take in good faith in accordance with a direction
     received by it pursuant to Section 6.05.

risk its own funds or incur any liability in the performance of any of its

indemnity satisfactory to it 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 with the Company.  Money held in trust by the
Trustee need not be segregated from other funds except to the extent required by
law.

SECTION 7.02   Rights of the Trustee.
               --------------------- 

     (a) The Trustee may rely on and shall be protected in acting or refraining
from acting upon any resolution, Officers' Certificate, or any other
certificate, statement, instrument, opinion, report, notice, request, consent,
order, security or other document believed by it to be

                                       36
<PAGE>
 
genuine and to have been signed or presented by the proper person.  The Trustee
need not investigate any fact or matter contained therein.

     (b) Any request, direction, order or demand of the Company mentioned herein
shall be sufficiently evidenced by an Officers' Certificate (unless other
evidence in respect thereof is herein specifically prescribed).  In addition,
before the Trustee acts or refrains from acting, it may require an Officers'
Certificate, 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.  The Trustee may consult with counsel and the

security or indemnity against the costs, expenses and liabilities which might be
incurred therein or thereby.

     (h) The Trustee shall not be bound to make any investigation into the facts
or matters stated in any resolution, certificate, statement, instrument,
opinion, report, notice, request, consent, order, security or other document
unless requested in writing to do so by the holders of not less than a majority
in aggregate principal amount of the Convertible Subordinated Notes then
outstanding, provided that if the Trustee determines in its sole and absolute
discretion to make any such investigation, then it shall be entitled, upon
reasonable prior notice and during normal business hours, to examine the books
and records and the premises of the Company, personally or by agent or attorney,
and the reasonable expenses of every such examination shall be paid by the
Company or, if paid by the Trustee or any predecessor Trustee, shall be
reimbursed by the Company upon demand.

                                       37
<PAGE>
 
SECTION 7.03   Individual Rights of the Trustee.
               -------------------------------- 

The Trustee in its individual or any other capacity may become the owner or
pledgee of Convertible Subordinated Notes with the same rights it would have if
it were not the Trustee and may otherwise deal with the Company or an Affiliate
and receive, collect, hold and retain collections from the Company with the same
rights it would have if it were not Trustee.  Any Agent may do the same with
like rights.  However, the Trustee is subject to Sections 7.10 and 7.11.

SECTION 7.04   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 Convertible Subordinated
Notes.  It shall not be accountable for the Company's use of the proceeds from
the Convertible Subordinated 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 Convertible Subordinated Notes or any
other document in connection with the sale of the Convertible Subordinated Notes
or pursuant to this Indenture other than its certificate of authentication.

SECTION 7.05   Notice of Defaults.
               ------------------ 

     If a Default or Event of Default occurs and is continuing and if it is
known to the Trustee, the Trustee shall mail to each holder of a Convertible
Subordinated Note a notice of the Default or Event of Default within 45 days
after it occurs.  A Default or an Event of Default shall not be considered known
to the Trustee unless it is a Default or Event of Default in the payment of
principal or interest when due under Section 6.01(a) or (b) or the Trustee shall
have received notice thereof, in accordance with this Indenture, from the
Company or from the holders of a majority in principal amount of the outstanding
Convertible Subordinated Notes.  Except in the case of a Default or Event of
Default in payment of principal or interest on any Convertible Subordinated
Note, the Trustee may withhold the notice if and so long as a committee of its
Trust Officers in good faith determines that withholding the notice is in the
interest of the holders of the Convertible Subordinated Notes.

SECTION 7.06   Reports by the Trustee to Holders.
               --------------------------------- 

     Within 60 days after the reporting date stated in Section 10.10, the
Trustee shall mail to holders of Convertible Subordinated Notes a brief report
dated as of such reporting date that complies with TIA (S) 313(a) (but if no
event described in TIA (S) 313(a) has occurred within twelve months preceding
the reporting date, no report need be transmitted).  The Trustee also shall
comply with TIA (S) 313(b)(2).  The Trustee shall also transmit by mail all
reports as required by TIA (S) 313(c).

                                       38
<PAGE>
 
     A copy of each report at the time of its mailing to holders of Convertible
Subordinated Notes shall be filed, at the expense of the Company, by the Trustee
with the Commission and each stock exchange, if any, on which the Convertible
Subordinated Notes are listed.  The Company shall timely notify the Trustee when
the Convertible Subordinated Notes are listed on any stock exchange.

SECTION 7.07   Compensation and Indemnity.
               -------------------------- 

     The Company shall pay to the Trustee from time to time and the Trustee
shall be entitled to reasonable compensation for its acceptance of this
Indenture and its services hereunder.  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 or on behalf of it in
addition to the compensation for its services.  Such expenses may include the
reasonable compensation, disbursements and expenses of the Trustee's agents,
counsel and other Persons not regularly in its employ.

     The Company shall indemnify the Trustee against any loss, liability or
expense incurred by it arising out of or in connection with the acceptance or
administration of its duties under this Indenture and the trusts hereunder,
including the costs and expenses of defending itself against or investigating
any claim of liability in the premises, except as set forth in the next
paragraph.  The Trustee shall notify the Company promptly of any claim for which
it may seek indemnity.  Failure by the Trustee to so notify the Company shall
not relieve the Company of its obligations hereunder.  The Company shall defend
the claim with counsel designated by the Company, who may be outside counsel to
the Company but shall in all events be reasonably satisfactory to the Trustee,
and the Trustee shall cooperate in the defense.  In addition, the Trustee may
retain one separate counsel and, if deemed advisable by such counsel, local
counsel, and the Company shall pay the reasonable fees and expenses of such
separate counsel and local counsel.  The indemnification herein extends to any
settlement, provided that the Company will not be liable for any settlement made
without its consent, provided, further, that such consent will not be
unreasonably withheld.

     The Company need not reimburse any expense or indemnify against any loss or
liability incurred by the Trustee through its own negligence or bad faith.

     To secure the Company's payment obligations in this Section 7.07, the
Trustee shall have a Lien prior to the Convertible Subordinated Notes on all
money or property held or collected by the Trustee, except that held in trust to
pay principal and interest on Convertible Subordinated Notes.  Such Liens and
the Company's obligations under this Section 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 6.01(g) or (h) occurs, the expenses and the
compensation for the services (including

                                       39
<PAGE>
 
the fees and expenses of its agents and counsel) are intended to constitute
expenses of administration under any Bankruptcy Law.

SECTION 7.08   Replacement of the 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 at any time and be discharged from the trust hereby
created by so notifying the Company.  The holders of a majority in principal
amount of the then outstanding Convertible Subordinated Notes may remove the
Trustee by so notifying the Trustee and the Company in writing and may appoint a
successor Trustee.  The Company may remove the Trustee if:

          (1) the Trustee fails to comply with Section 7.10;

          (2) 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;

          (3) a Custodian or public officer takes charge of the Trustee or its
     property; or

          (4) 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 a successor
Trustee.  Within one year after the successor Trustee takes office, the holders
of a majority in principal amount of the then outstanding Convertible
Subordinated 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 at least 10% in principal amount of the then outstanding Convertible
Subordinated Notes may petition any court of competent jurisdiction for the
appointment of a successor Trustee.

     If the Trustee after written request by any holder of a Convertible
Subordinated Note who has been a holder for at least six months fails to comply
with Section 7.10, such holder 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

                                       40
<PAGE>
 
holders of Convertible Subordinated Notes.  The retiring Trustee shall promptly
transfer all property held by it as Trustee to the successor Trustee, provided
that all sums owing to the retiring Trustee hereunder have been paid and subject
to the lien provided for in Section 7.07.  Notwithstanding the replacement of
the Trustee pursuant to this Section 7.08, the Company's obligations under
Section 7.07 shall continue for the benefit of the retiring Trustee.

     Upon request of any such successor Trustee, the Company shall execute any
and all instruments for more fully and certainly vesting in and confirming to
such successor Trustee all such rights, powers and trusts referred to in the
preceding paragraph.

SECTION 7.09   Successor Trustee by Merger, etc.
               ---------------------------------

     If the Trustee consolidates with, merges or converts into, or transfers all
or substantially all of its corporate trust business to, another corporation or
national banking association, the resulting, surviving or transferee corporation
or national banking association without any further act shall be the successor
Trustee with the same effect as if the successor Trustee had been named as the
Trustee herein.

SECTION 7.10   Eligibility, Disqualification.
               ----------------------------- 

     This Indenture shall always have a Trustee who satisfies the requirements
of TIA (S) 310(a)(1).  The Trustee shall always have a combined capital and
surplus as stated in Section 10.10.  The Trustee is subject to TIA (S) 310(b)
regarding the disqualification of a trustee upon acquiring a conflicting
interest.

SECTION 7.11   Preferential Collection of Claims Against Company.
               ------------------------------------------------- 

     The Trustee shall comply with TIA (S) 311(a), excluding any creditor
relationship set forth in TIA (S) 311(b).  A Trustee who has resigned or been
removed shall be subject to TIA (S) 311(a) to the extent indicated therein.


                                   ARTICLE 8

                    Satisfaction and Discharge of Indenture

SECTION 8.01   Termination of Company's Obligations.
               ------------------------------------ 

     (i) This Indenture shall cease to be of further effect (except that the
Company's obligations under Section 7.07 and 8.03 shall survive) when all
outstanding Convertible Subordinated Notes theretofore authenticated and issued
have been delivered (other than destroyed, lost or stolen Convertible
Subordinated Notes that have been replaced or paid) to the Trustee for
cancellation and the Company has paid all sums payable hereunder.  In addition,
the Company may terminate its obligations under this Indenture (except the
Company's obligations

                                       41
<PAGE>
 
under Sections 7.07 and 8.03) if, under terms satisfactory to the Trustee: (a)
the Convertible Subordinated Notes have either become due and payable or are by
their terms due and payable within one year or scheduled for redemption within
one year; and (b) the Company irrevocably deposits in trust with the Trustee
money or United States Government Obligations (defined below in this Section
8.01), or a combination thereof, sufficient, without consideration of the
reinvestment of interest in the opinion of the chief financial officer of the
Company expressed in a written certificate delivered to the Trustee, to pay
principal and interest on the Convertible Subordinated Notes to maturity or upon
redemption, as the case may be.  The Company may make the deposit only if
Article 11 permits it.

     However, the Company's obligations in Sections 2.03, 2.04, 2.05, 2.06,
2.07, 4.01, 4.04, 7.07, 7.08, 8.03 and 8.04 shall survive until the Convertible
Subordinated Notes are no longer outstanding.  Thereafter, only the Company's
obligations in Sections 7.07 and 8.03 shall survive.

     After a deposit made pursuant to this Section 8.01, the Trustee upon
request of the Company shall acknowledge in writing the discharge of the
Company's obligations under this Indenture except for those surviving
obligations specified above.

     In addition, the Company may elect to have either clause (ii) or clause
(iii) below be applied to the outstanding Convertible Subordinated Notes upon
compliance with the conditions set forth in clause (iv) below.

     (ii) Upon the Company's exercise under the last sentence of paragraph (i)
above of the option applicable to this paragraph (ii), the Company shall be
deemed to have been released and discharged from its obligations with respect to
the outstanding Convertible Subordinated Notes on the date the conditions set
forth below are satisfied ("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 Convertible Subordinated
Notes, which shall thereafter be deemed to be "outstanding" only for the purpose
of the Sections of and matters under this Indenture referred to in subclauses
(A), (B), (C) and (D) of this clause (ii), and to have satisfied all its other
obligations under such Convertible Subordinated Notes and this Indenture insofar
as such Convertible Subordinated Notes are concerned (and the Trustee, at the
expense of the Company, shall execute proper instruments acknowledging the
same), except for the following, which shall survive until otherwise terminated
or discharged hereunder: (A) the rights of holders of outstanding Convertible
Subordinated Notes to receive solely from the trust fund described in clause
(iv) below and as more fully set forth in such clause, payments in respect of
the principal of premium, if any, and interest on such Convertible Subordinated
Notes when such payments are due, (B) the Company's obligations with respect to
such Convertible Subordinated Notes when such payments are due, (C) the
Company's obligations with respect to such Convertible Subordinated Notes under
Sections 2.03, 2.05, 2.06, 2.07 and 4.04, and, with respect to the Trustee,
under Section 7.07, (D) the rights, powers, trusts, duties and immunities of the
Trustee hereunder and (E) this Section 8.01 and Sections 8.03 and 8.04.  Subject
to compliance with this Section 8.01, the Company may exercise its option under
this

                                       42
<PAGE>
 
clause (ii) notwithstanding the prior exercise of its option under paragraph
(iii) below with respect to the Convertible Subordinated Notes.

     (iii) Upon the Company's exercise under the last sentence of clause (i) of
the option applicable to this clause (iii), the Company shall be released and
discharged from its obligations under any covenant contained in Article 4
(except for Sections 4.01 and 4.04) and Article 5 with respect to the
outstanding Convertible Subordinated Notes on and after the date the conditions
set forth below are satisfied ("covenant defeasance"), and the Convertible
Subordinated Notes shall thereafter be deemed to be not "outstanding" for the
purpose of any direction, waiver, consent or declaration or act of holders of
Convertible Subordinated Notes (and the consequences of any thereof) in
connection with such covenants, but shall continue to be deemed "outstanding"
for all other purposes hereunder.  For this purpose, such covenant defeasance
means that, with respect to the outstanding Convertible Subordinated 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 6.01 but, except as specified
above, the remainder of this Indenture (including without limitation obligations
set forth in Sections 8.03 and 8.04 hereof) and such Convertible Subordinated
Notes shall be unaffected thereby.

     (iv) The following shall be the conditions to the application of either
clause (ii) or (iii) above to the outstanding Convertible Subordinated Notes:

       (a) the Company has irrevocably deposited in trust with the Trustee or,
     at the option of the Trustee, with a trustee, satisfactory to the Trustee
     and the Company, under terms of an irrevocable trust agreement in form and
     substance satisfactory to the Trustee, cash in U.S.  dollars, United States
     Government Obligations, or a combination thereof, in such amounts as will
     be sufficient, in the opinion of the Chief Financial Officer of the Company
     expressed in a written certificate delivered to the Trustee, to pay the
     principal of, premium, if any, and interest on the outstanding Convertible
     Subordinated Notes on the stated maturity or on the applicable redemption
     date, as the case may be, of such principal or installment of principal of,
     premium, if any, or interest on the outstanding Convertible Subordinated
     Notes; provided that (i) the trustee of the irrevocable trust shall have
     been irrevocably instructed to pay such money or the proceeds of such
     United States Government Obligations to the Trustee, (ii) the Trustee shall
     have been irrevocably instructed to apply such money or the proceeds of
     such United States Government Obligations to the payment of said principal
     and interest with respect to the Convertible Subordinated Notes, and (iii)
     such deposit does not violate Article 11 hereto;

          (b) in the case of an election under clause (ii) above, the Company
     shall have delivered to the Trustee an Opinion of Counsel from nationally

     of this Indenture, there has been a change in the applicable federal income
     tax law, in either case to the effect that the holders of the outstanding
     Convertible Subordinated 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 amount and in the same manner
     and at the same time as would have been the case if such legal defeasance
     had not occurred;

          (c) in the case of an election under clause (iii) above, the Company
     shall have delivered to the Trustee an Opinion of Counsel from nationally
     recognized counsel reasonably acceptable to the Trustee (i) to the effect
     that the holders of the outstanding Convertible Subordinated 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 amount and in the same manner and at the same time as would have
     been the case if such covenant defeasance had not occurred or (ii) that the
     Company has received from, or there has been published by, the Internal
     Revenue Service a ruling to the foregoing effect;

          (d) no Default or Event of Default shall have occurred and be
     continuing on the date of such deposit;

          (e) such legal defeasance or covenant defeasance shall not result in a
     breach or violation of, or constitute a Default or Event of Default under,
     any material agreement or instrument (including any agreement or instrument
     governing or evidencing Designated Senior Indebtedness) to which the
     Company or any of its subsidiaries is bound;

          (f) The Company shall deliver to the Trustee an Opinion of Counsel to
     the effect that after the 91st day following the deposit, the trust funds
     will not be subject to the effect of any applicable bankruptcy, insolvency,
     reorganization or similar laws affecting creditors' rights generally;

          (g) 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 Convertible Subordinated Notes over the
     other creditors of the Company with the intent of defeating, hindering,
     delaying or defrauding creditors of the Company or others; and

          (h) the Company has delivered to the Trustee an Officers' Certificate
     and an Opinion of Counsel stating that all conditions precedent provided
     for relating to the legal defeasance under clause (ii) above or the
     covenant defeasance under clause (iii) above, as the case may be, have been
     complied with.

     After such irrevocable deposit made pursuant to this Section 8.01 (and
satisfaction of the other conditions set forth herein), the Trustee upon request
shall acknowledge in writing the

                                       44
<PAGE>
 
discharge of the Company's obligations under this Indenture except for those
surviving obligations specified above.

     As used herein, "United States Government Obligations" means obligations
for which the full faith and credit of the United States of America is pledged
and which are not callable at the issuer's option.

SECTION 8.02   Application of Trust Money.
               -------------------------- 

     The Trustee shall hold in trust money or United States Government
Obligations deposited with it pursuant to Section 8.01.  It shall apply the
deposited money and the money from United States Government Obligations through
the Paying Agent and in accordance with this Indenture to the payment of
principal and interest on the Convertible Subordinated Notes.  Money and
securities so held in trust are not subject to Article 11.

SECTION 8.03   Repayment to Company.
               -------------------- 

     The Trustee and the Paying Agent shall promptly pay to the Company upon
request any excess money or securities held by them at any time.

     The Trustee and the Paying Agent shall pay to the Company upon request any
money held by them for the payment of principal or interest that remains
unclaimed for two years after the date upon which such payment shall have become
due; provided, however, that the Company shall have first caused notice of such
payment to the Company to be mailed to each holder of a Convertible Subordinated
Note entitled thereto no less than 30 days prior to such payment.  After payment
to the Company, holders entitled to the money must look to the Company for
payment as general creditors unless an applicable abandoned property law
designates another person and all liability of the Trustee and such Paying Agent
with respect to such money shall cease.

SECTION 8.04   Reinstatement.
               ------------- 

     If the Trustee or Paying Agent is unable to apply any money in accordance
with Section 8.02 by reason of any order or judgment of any court or
governmental authority enjoining, restraining or otherwise prohibiting such
application, the Company's obligations under this Indenture and the Convertible
Subordinated Notes shall be revived and reinstated as though no deposit had
occurred pursuant to Section 8.01 until such time as the Trustee or Paying Agent
is permitted to apply all such money in accordance with Section 8.02; provided,
however, that if the Company makes any payment of interest on or principal of
any Convertible Subordinated Note following the reinstatement of its
obligations, the Company shall be subrogated to the rights of the holders of
such Convertible Subordinated Notes to receive such payment from the money held
by the Trustee or Paying Agent.

                                   Amendments

SECTION 9.01  Without the Consent of Holders.
              ------------------------------ 

          The Company and the Trustee may amend this Indenture or the
Convertible Subordinated Notes without notice to or the consent of any holder of
a Convertible Subordinated Note for the purposes of:

          (a) adding to the covenants of the Company for the benefit of the
     holders of Convertible Subordinated Notes;

          (b) surrendering any right or power herein conferred upon the Company;

          (c) providing for conversion rights of holders of Convertible
     Subordinated Notes in the event of consolidation, merger or sale of all or
     substantially all of the assets of the Company and to otherwise comply with
     Section 5.01;

          (d) evidencing the succession of another Person to the Company and the
     assumption by such successor of the covenants and obligations of the
     Company thereunder and in the Convertible Subordinated Notes as permitted
     herein;

          (e) reducing the Conversion Price, provided that such reduction will
     not adversely affect the interests of holders of Convertible Subordinated
     Notes in any material respect; or

          (f) curing any ambiguity or correcting or supplementing any defective
     provision contained in this Indenture, or making any other changes in the
     provisions of this Indenture which the Company and the Trustee may deem
     necessary or desirable and which will not adversely affect the interest of
     the holders of Convertible Subordinated Notes.

SECTION 9.02   With the Consent of Holders.
               --------------------------- 

     Subject to Section 6.07, the Company and the Trustee may amend this
Indenture or the Convertible Subordinated Notes with the written consent of the
holders of at least a majority in principal amount of the then outstanding
Convertible Subordinated Notes.

     Subject to Sections 6.04 and 6.07, the holders of a majority in principal
amount of the Convertible Subordinated Notes then outstanding may also waive
compliance in a particular instance by the Company with any provision of this
Indenture or the Convertible Subordinated Notes.

                                       46
<PAGE>
 
     However, without the consent of each holder of a Convertible Subordinated
Note affected, an amendment or waiver under this Section may not:

          (a) reduce the amount of Convertible Subordinated Notes whose holders
     must consent to an amendment or waiver;

          (b) reduce the rate of, or extend the time for payment of, interest,
     including defaulted interest, on any Convertible Subordinated Note;

          (c) reduce the principal of or premium on or change the fixed maturity
     of any Convertible Subordinated Note or alter redemption provisions with
     respect thereto;

          (d) make the principal of, or premium, if any, or interest on, any
     Convertible Subordinated Note payable in money other than as provided for
     herein and in the Convertible Subordinated Notes;

          (e) waive continuing default in the payment of the principal of or
     premium, if any, or interest on, redemption or repurchase payment with
     respect to, any Convertible Subordinated Notes, including without
     limitation a continuing failure to make payment when required upon a Change
     of Control or after an Asset Sale Offer Trigger Date;

          (f) after the Company's obligation to purchase the Convertible
     Subordinated Notes arises hereunder, to then amend, modify or change the
     obligation of the Company to make or consummate a Change of Control Offer
     in the event of a Change of Control or an Asset Sale Offer in the event of
     an Asset Sale Offer Trigger Date or waive any default in the performance
     thereof or modify any of the provisions or definitions with respect to such
     offers;

          (g) modify the provision contained herein relating to conversion of or
     subordination of the Convertible Subordinated Notes in a manner adverse to
     the holders thereof; or

          (h) make any change in provisions relating to waivers of defaults, the
     abilities of holders of Convertible Subordinated Notes to enforce their
     rights hereunder or the provisions of clauses (a) through (h) of this
     Section 9.02.

     To secure a consent of the holders of Convertible Subordinated Notes under
this Section, it shall not be necessary for such holders 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 or waiver under this Section becomes effective, the
Company shall mail to holders of Convertible Subordinated Notes a notice briefly
describing the amendment or waiver.

                                       47
<PAGE>
 
     The Company agrees that no amendment, supplement or waiver under this
Article 9 may make any change that adversely affects the rights under Article 11
of any holders of any Designated Senior Indebtedness unless the percentage of
holders necessary to amend or waive terms of such Designated Senior Indebtedness
consent to such change.

SECTION 9.03   Compliance with the Trust Indenture Act.
               --------------------------------------- 

     Every amendment to this Indenture or the Convertible Subordinated Notes
shall be set forth in a supplemental indenture that complies with the TIA as
then in effect.


SECTION 9.04   Revocation and Effect of Consents.
               --------------------------------- 

     Until an amendment or waiver becomes effective, a consent to it by a holder
of a Convertible Subordinated Note is a continuing consent by the holder and
every subsequent holder of a Convertible Subordinated Note or portion of a
Convertible Subordinated Note that evidences the same debt as the consenting
holder's Convertible Subordinated Note, even if notation of the consent is not
made on any Convertible Subordinated Note.  However, any such holder or
subsequent holder may revoke the consent as to his or her Convertible
Subordinated Note or portion of a Convertible Subordinated Note if the Trustee
receives the notice of revocation before the date on which the Trustee receives
an Officers' Certificate certifying that the holders of the requisite principal
amount of Convertible Subordinated Notes have consented to the amendment or
waiver.

     The Company may, but shall not obligated to, fix a record date for the
purpose of determining the holders of Convertible Subordinated Notes entitled to
consent to any amendment or waiver.  If a record date is fixed, then
notwithstanding the provisions of the immediately preceding paragraph, those
persons who were holders of Convertible Subordinated Notes at such record date
(or their duly designated proxies), and only those persons, shall be entitled to
consent to such amendment or waiver or to 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
unless consents from holders of the principal amount of Convertible Subordinated
Notes required hereunder for such amendment or waiver to be effective shall have
also been given and not revoked within such 90-day period.

     After an amendment or waiver becomes effective it shall bind every holder
of a Convertible Subordinated Note, unless it is of the type described in any of
clauses (1) through (9) of Section 9.02.  In such case, the amendment or waiver
shall bind each holder of a Convertible Subordinated Note who has consented to
it.

SECTION 9.05   Notation on or Exchange of Convertible Subordinated Notes.
               --------------------------------------------------------- 

     Convertible Subordinated Notes authenticated and delivered after the
execution of any supplemental indenture pursuant to this Article 9 may, and
shall if required by the Trustee, bear a notation in the form approved by the
Trustee as to any matter provided for in such

                                       48
<PAGE>
 
supplemental indenture.  If the Company shall so determine, new Convertible
Subordinated Notes so modified as to conform, in the opinion of the Company and
the Trustee, to any such supplemental indenture may be prepared and executed by
the Company and authenticated and delivered by the Trustee in exchange for
outstanding Convertible Subordinated Notes.

SECTION 9.06   Trustee Protected.
               ----------------- 

     The Trustee shall sign any amendment or supplemental indenture authorized
pursuant to this Article 9 if such amendment or supplemental indenture does not
adversely affect the rights, duties, liabilities or immunities of the Trustee.
If it does, the Trustee may, but need not, sign it.  In signing such amendment
or supplemental indenture, the Trustee shall be entitled to receive, and shall
be fully protected in relying upon, an Officers' Certificate and an Opinion of
Counsel as conclusive evidence that such amendment or supplemental indenture is
authorized or permitted by this Indenture, that it is not inconsistent herewith,
and that it will be valid and binding upon the Company in accordance with its
terms.

the courier, if sent by overnight air courier guaranteeing next day delivery.

shown on the register kept

                                       49

by the Registrar.  Failure to mail a notice or communication to a holder or any
defect in it shall not affect its sufficiency with respect to other holders.

     If a notice or communication is sent in the manner provided above within
the time prescribed, it is duly given, whether or not the addressee receives it.

     If the Company sends a notice or communication to holders of Convertible
Subordinated Notes, it shall send a copy to the Trustee and each Agent at the
same time.

     All other notices or communications shall be in writing.

     conditions precedent and covenants have been complied with.

SECTION 10.05  Statements Required in Certificate or Opinion.
               --------------------------------------------- 

Each certificate or opinion with respect to compliance with a condition or
covenant provided for in this Indenture (other than a certificate provided

          (1) a statement that the person making such certificate or opinion has
     read such covenant or condition;

<PAGE>
 
          (3) a statement that, in the opinion of such person, he or she has

     Any Officers' Certificate may be based, insofar as it relates to legal
matters, upon an Opinion of Counsel, unless such Officer knows that the opinion
with respect to the matters upon which his certificate may be based as aforesaid
is erroneous.  Any Opinion of Counsel may be based, insofar as it relates to
factual matters, upon certificates, statements or opinions of, or
representations by an officer or officers of the Company, or other persons or
firms deemed appropriate by such counsel, unless such counsel knows that the
certificates, statements or opinions or representations with respect to the
matters upon which his certificate, statement or opinion may be based as

     A "Legal Holiday" is a Saturday, a Sunday or a day on which banking
institutions in the City of New York are not required to be open, and a business

time to time shall have any liability for any obligations of the Company under
the Convertible Subordinated Notes or this Indenture or for any claim based on,
in respect of, or by reason of such obligations or their creation.  Each holder
by accepting a Convertible Subordinated Note waives and releases all such
liability.  This waiver and release are part of the consideration for

                                       51

SECTION 11.01  Agreement To Subordinate.
               ------------------------ 

     The Company agrees, and each holder by accepting a Convertible Subordinated
Note agrees, that the indebtedness evidenced by the Convertible Subordinated
Notes is subordinated and junior in right of payment, to the extent and in the

benefit of the holders of Senior Indebtedness from time to time.

SECTION 11.02  Liquidation; Dissolution; Bankruptcy.
               ------------------------------------ 

     Upon any distribution to creditors of the Company in a liquidation,
reorganization or dissolution of the Company (in each case whether total or
partial) or in a bankruptcy, reorganization, insolvency, receivership or similar
proceeding or upon assignment for the benefit of creditors relating to the
Company or its property, or a marshalling of assets or liabilities of the
Company (in each case whether voluntary or involuntary);

          (1) holders of Senior Indebtedness shall first be entitled to be paid
     all obligations owing thereon or in respect thereof in full in cash or Cash
     Equivalents before any payment or distribution may be made on or in respect
     of the Convertible Subordinated Notes, except to the extent that holders
     receive securities that are subordinated to Senior Indebtedness to at least
     the same extent as the Convertible Subordinated Notes (the "Other
     Subordinated Securities"); and

          (2) holders of Convertible Subordinated Notes (or the Trustee on their
     behalf) will be required to pay over their share of such distribution
     directly to any Representative of the holders of Senior Indebtedness for
     payment thereto or, if such holders have no Representative, directly to
     such holders of Senior Indebtedness, until such Senior Indebtedness is paid
     in full in cash or Cash Equivalents except to the extent that holders of
     Convertible Subordinated Notes receive Other Subordinated Securities.

     For purposes of this Article 11, a distribution may consist of cash,
securities or other property, by payment, transfer, set-off or otherwise.

SECTION 11.03  Default on Designated Senior Indebtedness.
               ----------------------------------------- 

     The Company may not make any direct or indirect payment on or in respect of
any obligations on the Convertible Subordinated Notes and may not acquire or
defease any Convertible Subordinated Notes from the Trustee or any holder of
Convertible Subordinated Notes for cash or property (other than Other
Subordinated Securities) if:

          (a) a default in the payment of any principal or other obligation in
     respect of Designated Senior Indebtedness occurs and is continuing beyond
     any applicable grace period; or

                                       54
<PAGE>
 
          (b) a default, other than a default referred to in clause (a) above,
     on any Designated Senior Indebtedness occurs and is continuing that then
     permits holders of such Designated Senior Indebtedness to accelerate its
     maturity and the Trustee receives a notice of the default from the Bank
     Agent or other Representative on behalf of Designated Senior Indebtedness
     requesting that payments in respect of the Convertible Subordinated Notes
     be prohibited.

     So long as payments on the Convertible Subordinated Notes are otherwise
permitted, then the Company may and shall resume payments on the Convertible
Subordinated Notes and may acquire them upon the earlier of:

          (x) the date upon which such default is cured or waived, or

          (y) in the case of a default and notice referred to in (b) above, 179
     days after such notice is received by the Trustee (the "Payment Blockage
     Period").

     Only one Payment Blockage Period may be commenced within any consecutive
365-day period with respect to the Convertible Subordinated Notes.

SECTION 11.04  Acceleration of Convertible Subordinated Notes.
               ---------------------------------------------- 

     If payment of the Convertible Subordinated Notes is accelerated because of
an Event of Default, the Company and the Trustee each shall promptly notify
holders of Senior Indebtedness of the acceleration.

SECTION 11.05  When Distributions Must Be Paid Over.
               ------------------------------------ 

     In the event that any payment or distribution of assets of the Company,
whether in cash, property or securities (other than Other Subordinated
Securities) shall be received by the Trustee on account of the principal or
interest on or other obligations in respect of the Convertible Subordinated
Notes at a time when the Trustee shall have received notice in accordance with
Section 11.11 that such payment is prohibited by Section 11.02 or 11.03, such
payment or distribution shall be segregated and held by the Trustee in trust for
the benefit of, and shall forthwith be paid over and delivered to any
Representative of the holders of Senior Indebtedness for payments thereto, or,
if such holders have no Representative, directly to such holders of Senior
Indebtedness (pro rata as to each of such holders on the basis of the respective
amounts of Senior Indebtedness held by them), as their respective interests may
appear, for application to the payment of all Senior Indebtedness remaining
unpaid to the extent necessary to pay all Senior Indebtedness in full in cash or
Cash Equivalents in accordance with its terms, after giving effect to any
concurrent payment or distribution to or for the holders of Senior Indebtedness.
Any distribution to the holders of the Senior Indebtedness or their
Representatives of assets other than cash or Cash Equivalents may be held by
such holders or Representatives as collateral securing the payment of such
Senior Indebtedness without any duty to liquidate or otherwise realize on such
assets or to apply such assets to any Senior Indebtedness.

                                       55
<PAGE>
 
     If a payment or distribution is made to holders of Convertible Subordinated
Notes that because of this Article 11 should not have been made to them, the
holders of Convertible Subordinated Notes who receive the payment or
distribution shall hold it segregated from other assets and hold it in trust for
holders of Senior Indebtedness and pay it over to them as their interests may
appear for application to the payment of all Senior Indebtedness remaining
unpaid to the extent necessary to pay all Senior Indebtedness in full in cash or
Cash Equivalents in accordance with its terms, after giving effect to any
concurrent payment or distribution to or for the holders of Senior Indebtedness.

SECTION 11.06  Notice by the Company.
               --------------------- 

     The Company shall promptly notify the Trustee and the Paying Agent of any
facts known to the Company that would cause a payment of principal of or
interest on the Convertible Subordinated Notes to violate this Article, but
failure to give such notice shall not affect the subordination of the
Convertible Subordinated Notes to the Senior Indebtedness provided in this
Article.  Nothing in this Article shall apply to claims of, or payments to, the
Trustee under or pursuant to Section 7.07.

SECTION 11.07  Subrogation.
               ----------- 

     After all Senior Indebtedness is paid in full in cash or Cash Equivalents
and all letters of credit under the Revolving Credit Agreement have expired or
been terminated or the reimbursement obligations of the Company in respect of
such letters of credit then outstanding have been fully secured by cash or Cash
Equivalents and until the Convertible Subordinated Notes are paid in full,
holders of Convertible Subordinated Notes shall be subrogated to the rights of
holders of Senior Indebtedness to receive distributions applicable to Senior
Indebtedness to the extent that distributions otherwise payable to the holders
of Convertible Subordinated Notes have been applied to the payment of Senior
Indebtedness.  A distribution made under this Article to holders of Senior
Indebtedness which otherwise would have been made to holders of Convertible
Subordinated Notes is not, as between the Company and such holders, a payment by
the Company on Senior Indebtedness.

SECTION 11.08  Relative Rights.
               --------------- 

     This Article defines the relative rights of holders of Convertible
Subordinated Notes and holders of Senior Indebtedness.  Nothing in this
Indenture shall:

          (1) impair, as between the Company and holders of Convertible
     Subordinated Notes, the obligation of the Company, which is absolute and
     unconditional, to pay principal of and interest on the Convertible
     Subordinated Notes in accordance with their terms;

                                       56
<PAGE>
 
          (2) affect the relative rights of holders of Convertible Subordinated
     Notes and creditors of the Company, other than their rights in relation to
     holders of Senior Indebtedness; or

          (3) prevent the Trustee or any holder of a Convertible Subordinated
     Note from exercising its available remedies upon a Default or Event of
     Default, subject to the rights of holders of Senior Indebtedness to receive
     payments and distributions otherwise payable to holders of Convertible
     Subordinated Notes.

     If the Company fails because of this Article to pay principal of or
interest on a Convertible Subordinated Note on the due date, the failure is
still a Default or Event of Default.

SECTION 11.09  Subordination May Not Be Impaired by the Company.
               ------------------------------------------------ 

     No right of any holder of Senior Indebtedness to enforce the subordination
of the indebtedness evidenced by the Convertible Subordinated Notes shall be
impaired by any act or failure to act by the Company or by its failure to comply
with this Indenture (regardless of any knowledge thereof that such holder may
have or otherwise be charged with), or by any act or failure to act by such
holder.

     If at any time any payment of any obligations with respect to any Senior
Indebtedness is rescinded or must otherwise be returned upon the insolvency,
bankruptcy, reorganization or liquidation of the Company or otherwise, the
provisions of this Article 11 shall continue to be effective or reinstated, as
the case may be, to the same extent as though such payment had not been made.

SECTION 11.10  Distribution of Notice to the Representative.
               -------------------------------------------- 

     Whenever a distribution is to be made or a notice given to holders of
Senior Indebtedness, the distribution may be made and the notice given to their
Representative, if any.  Whenever a distribution is to be made or notice is to
be given to holders of the Company's outstanding 9.33% Senior Notes or its 9.35%
Senior Notes, such distribution shall be made and such notice shall be given to
each holder of record of such notes at the address specified in the register of
holders of such notes maintained by the Company.

     Upon any payment or distribution of assets of the Company referred to in
this Article 11, the Trustee and the holders of Convertible Subordinated Notes
shall be entitled to rely conclusively upon any order or decree made by any
court of competent jurisdiction or upon any certificate of any Representative
(as to the Senior Indebtedness for which it is the Representative) or of any
liquidating trustee or agent or an Officers' Certificate (as to any Senior
Indebtedness for which there is no Representative) for the purpose of
ascertaining the persons entitled to participate in such distribution, the
holders of the Senior Indebtedness and other indebtedness

                                       57
<PAGE>
 
of the Company, the amount thereof or payable thereon, the amount or amounts
paid or distributed thereon and all other facts pertinent thereto or to this
Article 11.

SECTION 11.11  Rights of the Trustee and Paying Agent.
               -------------------------------------- 

     Notwithstanding any provision of this Article 11 or any other provision of
this Indenture, the Trustee and the Paying Agent shall not at any time be
charged with knowledge of the existence of any facts which would prohibit the
making of any payment or distribution to or by the trustee or a Paying Agent or
the taking of any other action (pursuant to this Article 11) by the Trustee or a
Paying Agent unless and until the Trustee or such Paying Agent, as the case may
be, shall have received at its office specified in Section 10.10 written notice
thereof from the Company, a Representative or a holder of Senior Indebtedness
entitled to give such notice and, prior to the receipt of any such written
notice, the Trustee and such paying Agent shall be entitled in all respects
conclusively to assume that no such fact exists.  The Trustee or the Paying
Agent may continue to make payments on the Convertible Subordinated Notes unless
it receives such a notice at least one business day prior to the date upon which
payment is due.

     The Trustee shall be entitled to rely in good faith on the delivery to it
of a written notice by a Person representing himself, herself or itself to be a
Representative on behalf of a holder of Senior Indebtedness to establish that
such notice has been given by a Representative or a holder of such Senior
Indebtedness.  Only the Company, a Representative or a holder of Senior
Indebtedness that has no Representative may give the notice.

     The Trustee in its individual or any other capacity may hold Senior
Indebtedness with the same rights it would have if it were not the Trustee.  Any
Agent may do the same with like rights.

SECTION 11.12  No Fiduciary Duty to Holders of Senior Indebtedness.
               --------------------------------------------------- 

     With respect to the holders of Senior Indebtedness, the Trustee undertakes
to perform or to observe only such of its covenants and obligations as are
specifically set forth in this Article 11, and no implied covenants or
obligations with respect to the holders of Senior Indebtedness shall be read
into this Indenture against the Trustee or the Paying Agent.  Neither the
Trustee nor the Paying Agent shall be deemed to owe any fiduciary duty to the
holders of such Senior Indebtedness, and the Trustee shall not be liable to any
holder of such Senior Indebtedness if it shall, in the absence of bad faith, pay
over or deliver to holders of Convertible Subordinated Notes, the Company or any
other person monies or assets to which any holder of such Senior Indebtedness
shall be entitled by virtue of this Article 11 or otherwise.

SECTION 11.13  Authorization to Effect Subordination.
               ------------------------------------- 

     Each holder of a Convertible Subordinated Note by its or his acceptance
thereof authorizes and expressly directs the Trustee on its or his behalf to
take such action as may be necessary or appropriate to effect the subordination
provisions contained in this Article 11, and

                                       58
<PAGE>
 
appoints the Trustee its or his attorney-in-fact for such purpose, including, in
the event of any liquidation, reorganization or dissolution of the Company,
whether in a bankruptcy, reorganization, insolvency, receivership or similar
proceeding or otherwise, the immediate filing of a claim for the unpaid balance
of its or his Convertible Subordinated Notes in the form required in such
proceeding, and to cause such claim to be approved.  If the Trustee does not
file a proper claim or proof of debt in the form required in such proceeding
prior to 30 days before the expiration of the time to file such claim or claims,
then the holders of any Senior Indebtedness or their Representatives are hereby
authorized to file an appropriate claim for and on behalf of the holders of the
Convertible Subordinated Notes.


                                   ARTICLE 12

                  Conversion of Convertible Subordinated Notes

SECTION 12.01  Conversion Privilege.
               -------------------- 

     Subject to and upon compliance with the provisions of this Article 12, the
holder of any Convertible Subordinated Note shall have the right, at its option,
at any time on or prior to the close of business on May 15, 2004 (or, if such
Note or portion thereof is called for redemption prior to May 15, 2004, then in
respect of such Convertible Subordinated Note or portion thereof, on or prior to
the close of business on the date fixed for redemption, unless the Company shall
default in payment due upon redemption thereof in which case such conversion
right will terminate at the close of business on the date such default is
cured), to convert the principal amount of any such Convertible Subordinated
Note, or any portion of such principal amount which is $1,000 or an integral
multiple thereof, into that number of fully paid and nonassessable whole shares
of Common Stock obtained by dividing the principal amount of the Convertible
Subordinated Note or portion thereof to be converted by the Conversion Price in
effect at such time and by surrender of the Convertible Subordinated Note so to
be converted in whole or in part, such surrender to be made in the manner
provided in Section 12.02.

SECTION 12.02  Manner of Exercise of Conversion Privilege.
               ------------------------------------------ 

     In order to exercise the conversion privilege, the holder of any
Convertible Subordinated Note to be converted in whole or in part shall
surrender such Convertible Subordinated Note, duly endorsed or assigned to the
Company or in blank, at any of the offices or agencies to be maintained for such
purpose by the Company pursuant to Section 4.04, accompanied by the funds, if
any, required by the last paragraph of this Section, and shall give irrevocable
written notice of conversion in the form provided on the Convertible
Subordinated Notes (or such other notice as is acceptable to the Company) to the
Company (a "Conversion Notice") at such office or agency that the holder elects
to convert such Convertible Subordinated Note or the portion thereof specified
in said notice.  Such Conversion Notice shall also state the name or names,
together with the address or addresses, in which the certificate or certificates
for shares of Common Stock which shall be issuable in such conversion shall be
issued.  Each Convertible

                                       59
<PAGE>
 
Subordinated Note surrendered for conversion shall, unless the shares issuable
on conversion are to be issued in the same name as the name in which such
Convertible Subordinated Note is registered, be accompanied by instruments of
transfer, in form satisfactory to the Company, duly executed by the holder or
his duly authorized attorney and in amount sufficient to pay any transfer or
similar tax.  As promptly as practicable after the surrender of such Convertible
Subordinated Note and the receipt of such Conversion Notice, instruments of
transfer and funds, if any, as aforesaid, the Company shall issue and shall
deliver at such office or agency to such holder, or on his written order, a
certificate or certificates for the number of full shares of Common Stock
issuable upon the conversion of such Convertible Subordinated Note or portion
thereof in accordance with the provisions of this Article 12 and a check or cash
in respect of any fractional interest in a share of Common Stock arising upon
such conversion, as provided in Section 12.03.  In case any Convertible
Subordinated Note of a denomination greater than $1,000 shall be surrendered for
partial conversion, the Company shall execute and the Trustee shall register or
cause to be registered and shall authenticate and deliver to or upon the order
of the holder of the Convertible Subordinated Note so surrendered at the expense
of the Company, a new Convertible Subordinated Note in authorized denominations
in an aggregate principal amount equal to the unconverted portion of the
surrendered Note.

     Each conversion shall be deemed to have been effected immediately prior to
the close of business on the date on which such Convertible Subordinated shall
have been surrendered and such Conversion Notice (and any applicable instruments
of transfer and any required funds) received by the Company as aforesaid, and
the Person or Persons in whose name or names any certificate or certificates for
shares of Common Stock shall be issuable upon such conversion shall be deemed to
have become the holder or holders of record of the shares represented thereby at
such time on such date and such conversion shall be at the Conversion Price in
effect at such time on such date, unless the stock transfer books of the Company
shall be closed on that date, in which event such Person or Persons shall be
deemed to have become such holder or holders of record at the close of business
on the next succeeding day on which such stock transfer books are open, but such
conversion shall be at the Conversion Price in effect on the date upon which
such Convertible Subordinated Note shall have been surrendered and such
Conversion Notice received by the Company.

     Any Convertible Subordinated Note or portion thereof surrendered for
conversion after the close of business on a Regular Record Date for payment of
interest and before the close of business on the next succeeding Interest
Payment Date (unless such Convertible Subordinated Note or portion thereof being
converted is called for redemption on a redemption date in that period) shall be
accompanied by payment, in funds acceptable to the Company, of an amount equal
to the interest thereon that is to be paid on such Interest Payment Date on the
principal amount being converted; provided, however, that no such payment need
be made if there shall exist at the time of conversion a default in the payment
of interest on the Convertible Subordinated Notes.  An amount equal to such
payment shall be paid by the Company on such Interest Payment Date to the holder
of such Convertible Subordinated Notes at the close of business on such Regular
Record Date; provided, however, that, if the Company shall default in the
payment of interest on such Interest Payment Date, such amount shall be paid to
the

                                       60
<PAGE>
 
Person who made such required payment.  Except as provided for above in this
Section, no payments or adjustments shall be made upon conversion on account of
accrued interest on the Convertible Subordinated Notes or for any dividends or
distributions on any shares of Common Stock delivered upon the conversion of
such Convertible Subordinated Notes as provided in this Article.

SECTION 12.03  Cash Payments in Lieu of Fractional Shares.
               ------------------------------------------ 

     No fractional shares or scrip representing fractions of shares of Common
Stock shall be issued upon conversion of the Convertible Subordinated Notes.  If
more than one Convertible Subordinated Note shall be surrendered for conversion
at one time by the same holder, the number of full shares of Common Stock
issuable upon conversion thereof shall be computed on the basis of the aggregate
principal amount of the Convertible Subordinated Notes, or specified portions
thereof to be converted, so surrendered.  Instead of any fractional interest in
a share of Common Stock which would otherwise be deliverable upon the conversion
of any Convertible Subordinated Note or Convertible Subordinated Notes, the
Company shall pay to the holder of such Convertible Subordinated Note an amount
in cash (computed to the nearest cent) equal to the Daily Market Price thereof
at the close of business on the business day next preceding the day of
conversion multiplied by the fractional interest (expressed as a percentage)
that otherwise would have been deliverable to such holder upon such conversion
of the Convertible Subordinated Notes.

SECTION 12.04  Adjustment of Conversion Price.
               ------------------------------ 

     The Conversion Price shall be as specified in the form of Convertible
Subordinated Note set forth in Article 17 thereof subject to adjustment as
provided below.  The Conversion Price shall be adjusted from time to time by the
Company as follows:

          (a) In case the Company, after the date of this Indenture, shall (i)
     pay a dividend or make a distribution on its Common Stock in shares of
     Common Stock, (ii) subdivide its outstanding shares of Common Stock into a
     greater number of shares, (iii) combine its outstanding shares of Common
     Stock into a smaller number of shares, or (iv) issue by reclassification of
     its Common Stock any shares of Capital Stock of the Company, the Conversion
     Price in effect immediately prior to such action shall be adjusted so that
     the holder of any Convertible Subordinated Note thereafter surrendered for
     conversion shall be entitled to receive the number of shares of Common
     Stock or other Capital Stock of the Company that it would have owned or
     been entitled to receive immediately following such action had such
     Convertible Subordinated Note been converted immediately prior to the
     occurrence of such event.  An adjustment made pursuant to this subsection
     (a) shall become effective immediately after the record date, in the case
     of a dividend or distribution, or immediately after the effective date, in
     the case of a subdivision, combination or reclassification.  If, as a
     result of an adjustment made pursuant to this subsection (a), the holder of
     any Convertible Subordinated Note thereafter surrendered for conversion
     shall become entitled to receive shares of two or more classes of Capital

                                       61
<PAGE>
 
     Stock or shares of Common Stock and other Capital Stock of the Company, the
     Board of Directors (whose determination shall be conclusive and shall be
     described in a statement filed by the Company with the Trustee and with any
     Conversion Agent as soon as practicable) shall determine the allocation of
     the adjusted Conversion Price between or among shares of such classes of
     Capital Stock or shares of Common Stock and other Capital Stock.

          (b) In case the Company, after the date of this Indenture, shall issue
     rights, warrants or options to all holders of its outstanding shares of
     Common Stock entitling them to subscribe for or purchase shares of Common
     Stock (or securities convertible into Common Stock) at a price per share
     less than the current market price per share (as determined pursuant to
     subsection (h) of this Section 12.04) of the Common Stock, the Conversion
     Price in effect immediately prior thereto shall be adjusted so that it
     shall equal the price determined by multiplying the Conversion Price in
     effect immediately prior to the date of issuance of such rights, warrants
     or options by a fraction of which the numerator shall be the number of
     shares of Common Stock outstanding on the date of issuance of such rights,
     warrants or options (immediately prior to such issuance), plus the number
     of shares of Common Stock which the aggregate offering price of the total
     number of shares of Common Stock so offered for subscription or purchase
     (or the aggregate conversion price of the convertible securities so offered
     for subscription or purchase) would purchase at such current market price,
     and of which the denominator shall be the number of shares of Common Stock
     outstanding on the date of issuance of such rights, warrants or options
     (immediately prior to such issuance) plus the number of additional shares
     of Common Stock so offered for subscription or purchase (or into which the
     convertible securities so offered for subscription or purchase are
     convertible).  Such adjustment shall be made successively whenever any such
     rights, warrants or options are issued, and shall become effective
     immediately after the record date for the determination of stockholders
     entitled to receive such rights, warrants or options.  In determining
     whether any rights, warrants or options entitle the holders to subscribe
     for or purchase shares of Common Stock (or securities convertible into
     Common Stock) at less than such current market price, and in determining
     the aggregate offering price of such shares of Common Stock (or conversion
     price of such convertible securities), there shall be taken into account
     any consideration received by the Company for such rights, warrants or
     options (and for such convertible securities), the value of such
     consideration, if other than cash, to be determined by the Board of
     Directors (whose determination shall be conclusive and shall be described
     in a certificate filed with the Trustee and with any Conversion Agent by
     the Company as soon as practicable).  If at the end of the period during
     which such warrants, rights or options are exercisable not all such
     warrants, rights or options shall have been exercised, the adjusted
     Conversion Price shall be immediately readjusted to what it would have been
     based on the number of additional shares of Common Stock actually issued
     (or the number of shares of Common Stock issuable upon conversion of
     convertible securities actually issued).

                                       62
<PAGE>
 
          (c) In case the Company, after the date of this Indenture, shall
     distribute to all or substantially all holders of its outstanding Common
     Stock any shares of Capital Stock (other than Common Stock), evidences of
     its indebtedness or assets (including securities and cash, but excluding
     any cash dividend paid out of current or retained earnings of the Company
     and dividends or distributions payable in stock for which adjustment is
     required pursuant to subsection (a) of this Section 12.04) or rights,
     warrants or options to subscribe for or purchase securities of the Company
     (excluding those referred to in subsection (b) of this Section 12.04), then
     in each such case the Conversion Price shall be adjusted so that the same
     shall equal the price determined by multiplying the Conversion Price in
     effect immediately prior to the record date of such distribution by a
     fraction of which the numerator shall be the current market price per share
     (as determined pursuant to subsection (h) of this Section 12.04) of the
     Common Stock less the fair market value on such record date (as determined
     by the Board of Directors, whose determination shall be conclusive and
     shall be described in a certificate filed with the Trustee and with any
     Conversion Agent by the Company as soon as practicable) of the portion of
     the Capital Stock or the evidences of indebtedness or the assets so
     distributed to the holder of one share of Common Stock or of such
     subscription rights, warrants or options applicable to one share of Common
     Stock and of which the denominator shall be such current market price per
     share of Common Stock.  Such adjustment shall become effective immediately
     after the record date for the determination of stockholders entitled to
     receive such distribution.  In the event of a distribution to all or
     substantially all holders of Common Stock of rights to subscribe for
     additional shares of the Company's Capital Stock (other than those referred
     to in subsection (b) of this Section 12.04), the Company may, instead of
     making an adjustment in the Conversion Price, make proper provision so that
     each holder of a Convertible Subordinate Note who converts such Convertible
     Subordinated Note after the record date for such distribution and prior to
     the expiration or redemption of such rights shall be entitled to receive
     upon such conversion, in addition to shares of Common Stock, an appropriate
     number of such rights.  If at the end of the period during which warrants,
     rights or options described in this subsection (c) are exercisable not all
     such warrants, rights or options shall have been exercised, the adjusted
     Conversion Price shall be immediately readjusted to what it would have been
     based on the number of warrants, rights or options actually exercised.

          (d) Notwithstanding anything in subsection (b) or (c) of this Section
     12.04 to the contrary, with respect to any rights, warrants or options
     covered by subsection (b) or (c) of this Section 12.04, if such rights,
     warrants or options are only exercisable upon the occurrence of certain
     triggering events, then for purposes of this Section 12.04 such rights,
     warrants or options shall not be deemed issued or distributed, and any
     adjustment to the Conversion Price required by subsection (b) or (c) of
     this Section 12.04 shall not be made until such triggering events occur and
     such rights, warrants or options become exercisable.

          (e) In case the Company, after the date of this Indenture, shall issue
     to an Affiliate shares of its Common Stock (excluding those rights,
     warrants, options, shares

     of Capital Stock or evidences of its indebtedness or assets referred to in
     subsection (b) or (c) to this Section 12.04) at a net price per share less
     than the current market price per share (as determined pursuant to
     subsection (h) of this Section 12.04) on the date the Company fixes the
     offering price of such additional shares, the Conversion Price shall be
     reduced immediately thereafter so that it shall equal the price determined
     by multiplying such Conversion Price in effect immediately prior thereto by
     a fraction of which the numerator shall be the number of shares of Common
     Stock outstanding immediately prior to the issuance of such additional
     shares plus the number of shares of Common Stock which the aggregate
     offering price of the total number of shares of Common Stock so offered
     would purchase at the current market price and the denominator shall be the
     number of shares of Common Stock that would be outstanding immediately
     after the issuance of such additional shares.  Such adjustment shall be
     made successively whenever such an issuance is made.  This subsection (e)
     shall not apply to Common Stock issued to any Affiliate under a bona fide
     employee or director benefit plan or agreement adopted by the Company or
     any subsidiary thereof and approved by either the stockholders of the
     Company or a majority of the Company's outside directors.

          (f) In case the Company, after the date of this Indenture, shall, by
     dividend or otherwise, at any time distribute to all holders of its Common
     Stock cash (including any cash that is distributed as part of a
     distribution referred to in subsection (c) of this Section) in an aggregate
     amount that, together with (i) the aggregate amount of any other
     distributions to all holders of its Common Stock made exclusively in cash
     within the 12 months preceding the date fixed for determining the
     stockholders entitled to such distribution and in respect of which no
     Conversion Price adjustment pursuant to this subsection (f) has been made
     and (ii) the aggregate of any cash plus the fair market value (as
     determined by the Board of Directors, whose determination shall be
     conclusive and described in a Board Resolution), as of such date of
     determination, of consideration payable in respect of any tender offer by
     the Company or a subsidiary for all or any portion of the Common Stock
     consummated within 12 months preceding the date fixed for determining the
     stockholders entitled to such distribution and in respect of which no
     Conversion Price adjustment pursuant to subsection (g) of this Section has
     been made, exceeds 15% of the product of the current market price per share
     (determined as provided in subsection (h) of this Section) on the date
     fixed for the determination of stockholders entitled to receive such
     distribution times the number of shares of Common Stock outstanding on such
     date, the Conversion Price shall be reduced by multiplying such Conversion
     Price by a fraction of which the numerator shall be the current market
     price per share (determined as provided in subsection (h) of this Section)
     on the date fixed for such determination less the amount of cash so
     distributed at such time applicable to one share of Common Stock and the
     denominator shall be such current market price, such reduction to become
     effective immediately prior to the opening of business on the date after
     the date fixed for such determination.

          (g) In case a tender offer made by the Company or any subsidiary,
     after the date of this Indenture, for all or any portion of the Common
     Stock shall be consummated and

                                       64
<PAGE>
 
     such tender offer shall involve an aggregate consideration having a fair
     market value (as determined by the Board of Directors, whose determination
     shall be conclusive and described in a Board Resolution) as of the last
     time (the "Expiration Time") that tenders may be made pursuant to such
     tender offer (as it may be amended) that, together with (i) aggregate of
     the cash plus the fair market value (as determined by the Board of
     Directors, whose determination shall be conclusive and described in a Board
     Resolution), as of the consummation of such tender offer, of other
     consideration paid or payable in respect of any tender offer by the Company
     or a subsidiary for all or any portion of the Common Stock consummated
     within the 12 months preceding the consummation of such tender offer and in
     respect of which no Conversion Price adjustment pursuant to this subsection
     (g) has been made and  (ii) the aggregate amount of any distributions to
     all holders of Common Stock made exclusively in cash within the 12 months
     preceding the consummation of such tender offer and in respect of which no
     Conversion Price adjustment pursuant to subsection (f) of this Section has
     been made, exceeds 15% of the product of the current market price per share
     (determined as provided in subsection (h) of this Section) immediately
     prior to the Expiration Time times the number of shares of Common Stock
     outstanding (including any tendered shares) at the Expiration Time, the
     Conversion Price shall be reduced by multiplying the Conversion Price in
     effect immediately prior to the Expiration Time by a fraction of which the
     numerator shall be (i) the product of the current market price per share
     (determined as provided in subsection (h) of this Section) immediately
     prior to the Expiration Time times the number of shares of Common Stock
     outstanding (including any tendered shares) at the Expiration Time minus
     (ii) the fair market value (determined as aforesaid) of the aggregate
     consideration payable to stockholders upon consummation of such tender
     offer (the shares accepted for payment in the tender offer being referred
     to as the "Purchased Shares") and the denominator shall be the product of
     (x) such current market price per share times (y) such number of
     outstanding shares at the Expiration Time minus the number of Purchased
     Shares, such reduction to become effective immediately prior to the opening
     of business on the day following the Expiration Time; provided that if the
     number of Purchased Shares or the aggregate consideration payable therefor
     have not been finally determined by such opening of business, the
     adjustment required by this subsection (g) shall, pending such final
     determination, be made based upon the preliminary announced results of such
     tender offer, and, after such final determination shall have been made, the
     adjustment required by this subsection (g) shall be made based upon the
     number of Purchased Shares and the aggregate consideration payable therefor
     as so finally determined.

          (h) For the purpose of any computation under subsections (b) through
     (g) of this Section 12.04, the current market price per share of Common
     Stock on any date shall be deemed to be the average of the Daily Market
     Prices for the shorter of (i) 30 consecutive business days ending on the
     last full trading day on the exchange or market referred to in determining
     such Daily Market Prices prior to the Time of Determination or (ii) the
     period commencing on the date next succeeding the first public announcement
     of the

                                       65
<PAGE>
 
     issuance of such rights or warrants or such distribution through such last
     full trading day prior to the Time of Determination.

          (i) In any case in which this Section 12.04 shall require that an
     adjustment be made immediately following a record date or an effective
     date, the Company may elect to defer (but only until five business days
     following the filing by the Company with the Trustee and any Conversion
     Agent of the certificate required by subsection (k) of this Section 12.04)
     issuing to the holder of any Convertible Subordinated Note converted after
     such record date or effective date the shares of Common Stock issuable upon
     such conversion over and above the shares of Common Stock issuable upon
     such conversion on the basis of the Conversion Price prior to adjustment,
     and paying to such holder any amount of cash in lieu of a fractional share.

          (j) No adjustment in the Conversion Price shall be required to be made
     unless such adjustment would require an increase or decrease of at least 1%
     in such price; provided, however, that any adjustments which by reason of
     this subsection (j) are not required to be made shall be carried forward
     and taken into account in any subsequent adjustment.  All calculations
     under this Section 12.04 shall be made to the nearest cent or to the
     nearest 1/100th of a share, as the case may be.  No adjustment to the
     Conversion Price need be made if only the par value of the Common Stock is
     changed (including any change to no par value Common Stock).  To the extent
     that the Notes become convertible into cash, no adjustment need be made
     thereafter as to such cash and interest will not accrue on such cash.
     Anything in this Section 12.04 to the contrary notwithstanding, the Company
     shall be entitled to make such reduction in the Conversion Price, in
     addition to those required by this Section 12.04, as it in its discretion
     shall determine to be advisable in order that any stock dividend,
     subdivision of shares, distribution of rights to purchase stock or
     securities, or distribution of securities convertible into or exchangeable
     for stock hereafter made by the Company to its stockholders shall not be
     taxable to the recipients.

          (k) Whenever the Conversion Price is adjusted as herein provided, (i)
     the Company shall promptly file with the Trustee and any Conversion Agent
     other than the Trustee a certificate signed by the President, any Vice
     President or the Treasurer of the Company setting forth the Conversion
     Price after such adjustment and setting forth a brief statement of the
     facts requiring such adjustment and the manner of computing the same, which
     certificate shall be conclusive evidence of the correctness of such
     adjustment, and (ii) a notice stating that the Conversion Price has been
     adjusted and setting forth the adjusted Conversion Price shall forthwith be
     given by the Company to the holders of Convertible Subordinated Notes in
     the manner provided in Section 10.02.  The Company may correct any previous
     certificate and notice given pursuant to this subsection (k) by (i)
     promptly filing with the Trustee and any Conversion Agent other than the
     Trustee a new certificate in the form required by this subsection (k) and
     (ii) giving a new notice to the holders of Convertible Subordinated Notes
     in the form and manner required by this subsection (k).  Such new
     certificate and notice shall state that

                                       66
<PAGE>
 
     such certificate and notice are being provided to correct the previous
     certificate and notice.  Except as otherwise provided in Section 7.01,
     neither the Trustee nor any Conversion Agent shall be under any duty or
     responsibility with respect to the certificate required by this subsection
     (k) except to exhibit the same to any holder of Convertible Subordinated
     Notes who requests to inspect it.  The certificate required by this
     subsection (k) shall be filed at each office or agency maintained for the
     purposes of conversion of Notes pursuant to Section 2.03.

          (l) In the event that at any time, as a result of an adjustment made
     pursuant to subsection (a) of this Section 12.04, the holder of any
     Convertible Subordinated Note thereafter surrendered for conversion shall
     become entitled to receive any shares of the Company other than shares of
     Common Stock, thereafter the Conversion Price of such other shares so
     receivable upon conversion of any Note shall be subject to adjustment from
     time to time in a manner and on terms as nearly equivalent as practicable
     to the provisions with respect to Common Stock contained in this Article 12
     and the other provisions of this Article 12 applicable to Common Stock
     shall apply to such other shares.

SECTION 12.05  Notice to Holders Prior to Certain Corporate Actions.
               ---------------------------------------------------- 

     In case:

          (a) the Company shall take any action that would require an adjustment
     in the Conversion Price pursuant to Section 12.04(c); or

          (b) the Company shall authorize the granting to the holders of its
     Common Stock generally of rights, warrants or options to subscribe for or
     purchase any shares of stock of any class or of any other rights (other
     than employee or director stock options); or

          (c) there shall be any reorganization or reclassification of the
     Common Stock (other than a subdivision or combination of the outstanding
     Common Stock and other than a change in the par value of the Common Stock),
     or any consolidation or merger to which the Company is a party, or any
     conveyance, transfer, sale or lease of the Company's properties and assets
     as, or substantially as, an entirety; or

          (d) there shall be a voluntary or involuntary dissolution, liquidation
     or winding up of the Company;

then the Company shall cause to be filed with the Trustee and any Conversion
Agent, and shall cause to be given to the holders of Convertible Subordinated
Notes, in the manner provided in Section 10.02, as promptly as possible, but in
any event at least 10 days prior to the applicable date hereinafter specified, a
notice stating (i) the date on which a record is to be taken for the purpose of
such dividend, or distribution or rights or warrants, or, if a record is not to
be taken, the date as of which the holders of Common Stock of record to be
entitled to such distribution

                                       67
<PAGE>
 
or rights are to be determined, or (ii) the date on which such reorganization,
reclassification, consolidation, merger, conveyance, transfer, sale, lease,
dissolution, liquidation or winding up is expected to become effective or occur,
and, if applicable, the date as of which it is expected that holders of Common
Stock of record shall be entitled to exchange their shares of Common Stock for
securities, cash or other property deliverable upon such reorganization,
reclassification, consolidation, merger, conveyance, transfer, sale, lease,
liquidation or winding up.  Failure to give such notice or any defect therein
shall not affect the legality or validity of the proceedings described in
subsection (a), (b), (c) or (d) of this Section 12.05.

SECTION 12.06  Reservation of Shares of Common Stock.
               ------------------------------------- 

     The Company shall at all times reserve and keep available, free from
preemptive rights, out of the aggregate of its authorized but unissued shares of
Common Stock or its issued shares of Common Stock held in its treasury, or both,
for the purpose of effecting conversions of Convertible Subordinated Notes, the
full number of shares of Common Stock deliverable upon the conversion of all
outstanding Notes not theretofore converted.

     Before taking any action that would cause an adjustment reducing the
Conversion Price below the then par value (if any) of the shares of Common Stock
deliverable upon conversion of the Convertible Subordinated Notes, the Company
shall take any corporate action which may, in the opinion of its counsel, be
necessary in order that the Company may validly and legally issue fully paid and
nonassessable shares of Common Stock at such adjusted Conversion Price.

SECTION 12.07  Taxes upon Conversion.
               --------------------- 

     The Company shall pay any and all documentary, stamp or similar issue or
transfer taxes payable in respect of the issue or delivery of shares of Common
Stock on conversions of Notes pursuant hereto; provided, however, that the
Company shall not be required to pay any tax which may be payable in respect of
any transfer involved in the issue or delivery of shares of Common Stock in a
name other than that of the holder of the Convertible Subordinated Note or
Convertible Subordinated Notes to be converted and no such issue or delivery
shall be made unless and until the Person requesting such issue or delivery has
paid to the Company the amount of any such tax or has established to the
satisfaction of the Company that such tax has been paid.

SECTION 12.08  Covenants as to Common Stock.
               ---------------------------- 

     The Company covenants that all shares of Common Stock which may be
delivered upon conversions of Convertible Subordinated Notes will upon delivery
be duly and validly issued and fully paid and nonassessable, free of all Liens
and charges and not subject to any preemptive rights.

                                       68
<PAGE>
 
     The Company further covenants that, for so long as the Common Stock shall
be listed on the New York Stock Exchange or any other national securities
exchange, the Company will, if permitted by the rules of such exchange, list and
keep listed all Common Stock issuable upon conversion of the Convertible
Subordinated Notes.

SECTION 12.09  Consolidation or Merger or Sale of Assets.
               ----------------------------------------- 

     Notwithstanding any other provision herein to the contrary, in case of any
consolidation or merger to which the Company is a party (other than a merger or
consolidation which does not result in any reclassification, conversion,
exchange or cancellation of the outstanding shares of Common Stock of the
Company), or in case of any conveyance, transfer, sale or lease to another
corporation of the properties and assets of the Company as, or substantially as,
an entirety, the corporation formed by such consolidation, or the corporation
whose securities, cash or other property will immediately after the merger or
consolidation be owned, by virtue of the merger or consolidation, by the holders
of Common Stock of the Company immediately prior to the merger or the
corporation which shall have acquired such properties and assets of the Company,
as the case may be, shall promptly execute and deliver to the Trustee a
supplemental indenture providing that the holder of each Convertible
Subordinated Note then outstanding shall have the right thereafter to convert
such Note, during the period such Note is convertible as specified in this
Article 12, into the kind and amount of securities, cash or other property
receivable upon such consolidation, merger, conveyance, transfer, sale or lease
by a holder of the number of shares of Common Stock into which such Note might
have been converted immediately prior to such consolidation, merger, conveyance,
transfer, sale or lease, assuming such holder of Common Stock (i) is not a
Person with which the Company consolidated or into which the Company merged or
was merged or to which such conveyance, transfer, sale or lease was made or an
Affiliate of such Person and (ii) did not exercise statutory rights of election,
if any, as to the kind or amount of securities, cash or other property
receivable upon such consolidation, merger, conveyance, transfer, sale or lease
(provided that if the kind or amount of securities, cash or other property
receivable upon such consolidation, merger, conveyance, transfer, sale or lease
is not the same for each share of Common Stock in respect of which such rights
of election shall not have been exercised ("non-electing share"), then for the
purposes of this Section 12.09 the kind and amount of securities, cash or other
property receivable upon such consolidation, merger, conveyance, transfer, sale
or lease for each non-electing share shall be deemed to be the kind and amount
so receivable per share by the holders of a plurality of the non-electing
shares).  Such supplemental indenture shall provide for adjustments which, for
events subsequent to the effective date of such supplemental indenture, shall be
as nearly equivalent as may be practicable to the adjustments provided for in
this Article 12 in relation to any shares of stock or other securities or
property thereafter deliverable on the conversion of the Notes.

     The above provisions of this Section 12.09 shall similarly apply to
successive consolidations, mergers, conveyances, transfers, sales or leases.

                                       69
<PAGE>
 
     The Company shall give notice of the execution of such a supplemental
indenture to the holders of Convertible Subordinated Notes in the manner
provided in Section 10.02 within 30 days after the execution thereof; provided,
however, that such notice need not be given if such information has been
provided prospectively in the notice given pursuant to Section 12.05.  Failure
to give such notice, or any defects therein, shall not affect the legality or
validity of any such supplemental indenture or any transaction contemplated in
this Section 12.09.

SECTION 12.10  Disclaimer of Responsibility for Certain Matters.
               ------------------------------------------------ 

     Neither the Trustee nor any Conversion Agent shall at any time be under any
duty or responsibility to any holder of Convertible Subordinated Notes to
determine whether any facts exist which may require any adjustment of the
Conversion Price, or with respect to the nature or extent of any such adjustment
when made, or with respect to the method employed, or herein or in any
supplemental indenture provided to be employed, in making the same.  Neither the
Trustee nor any Conversion Agent shall be accountable with respect to the
listing or registration referred to in Section 12.08 or the validity or value
(or the kind or amount) of any shares of Common Stock, or of any securities,
cash or other property, which may at any time be issued or delivered upon the
conversion of any Note; and neither the Trustee nor any Conversion Agent makes
any representation with respect thereto.  Neither the Trustee nor any Conversion
Agent shall be responsible for any failure of the Company to issue, transfer or
deliver any shares of Common Stock or stock certificates or other securities or
property or to make any cash payment upon the surrender of any Note for the
purpose of conversion or, subject to the provisions of Section 7.01, to comply
with any of the covenants of the Company contained in this  Article 12.

SECTION 12.11  Cancellation of Converted Notes.
               ------------------------------- 

     All Notes delivered for conversion shall be delivered to the Trustee to be
cancelled by or at the direction of the Trustee, which shall dispose of the same
as provided in Section 2.11.

SECTION 12.12  Voluntary Reduction.
               ------------------- 

     The Company from time to time may reduce the Conversion Price by any amount
for any period of time if the period is at least 20 days or such longer period
as may be required by law and if the reduction is irrevocable during such
period.

                                       70

                 7 3/4% CONVERTIBLE SUBORDINATED NOTE DUE 2004

     1.   INTEREST.  Rohr, Inc., a Delaware corporation (the "Company"),
promises to pay interest on the principal amount of this Convertible
Subordinated Note at the rate per annum shown above.  The Company will pay
interest semiannually on May 15 and November 15 of each year.  Interest on the
Convertible Subordinated Notes will accrue from the most recent date to which
interest has been paid or, if no interest has been paid, from May 19, 1994.
Interest will be computed on the basis of a 360-day year of twelve 30-day
months.

     2.   METHOD OF PAYMENT.  The Company will pay interest on the Convertible
Subordinated Notes (except defaulted interest) to the person in whose name each
Convertible Subordinated Note is registered at the close of business on the May
1 or November 1 immediately preceding the relevant interest payment date (each a
"Regular Record Date") even though Convertible Subordinated Notes are cancelled
after the record date and on or before the interest payment date.  Holders must
surrender Convertible Subordinated Notes to a Paying Agent to collect principal
payments.  The Company will pay principal and interest in money of the United
States that at the time of payment is legal tender for payment of public and
private debts.  However, the Company may pay principal and interest by check
payable in such money, and may mail such check to the holder's registered
address.

     3.   PAYING AGENT AND REGISTRAR.  The Bank of New York, a New York State
banking corporation (together with any successor Trustee under the Indenture
referred to below, the "Trustee"), will act as Paying Agent and Registrar.  The
Company may change the Paying Agent, Registrar or co-registrar without prior
notice.  Subject to certain limitations in the Indenture, the Company or any of
its subsidiaries may act in any such capacity.

     4. INDENTURE. The Company issued the Convertible Subordinated Notes under
an Indenture dated as of May 15, 1994 (the "Indenture") between the Company and
the Trustee. The terms of the Convertible Subordinated Notes include those
stated in the Indenture and those made part of the Indenture by reference to the
Trust Indenture Act of 1939 (15 U.S. Code (S) (S) 77aaa-77bbbb) as in effect on
the date of the Indenture. The Convertible Subordinated Notes are subject to,
and qualified by, all such terms, certain of which are summarized hereon, and
holders are referred to the Indenture and such Act for a statement of such
terms. The Convertible Subordinated Notes are unsecured general obligations of
the Company limited to (except as otherwise provided in the Indenture) up to
$50,000,000 in aggregate principal amount, unless an election has been made as
set forth in Article 2 of the Indenture to increase such aggregate principal
amount by an amount not to exceed $7,500,000. Capitalized terms not defined
below have the same meaning as is given to them in the Indenture.

     5.   OPTIONAL REDEMPTION.  The Company may redeem the Convertible
Subordinated Notes, in whole or in part, prior to maturity at any time on or

of the principal amount), plus accrued and unpaid interest to the date fixed for

          2004...................................      100.000%
</TABLE>

     6. NOTICE OF REDEMPTION. Notice of redemption will be mailed at least 30
days but not more than 60 days before the date fixed for redemption to each
holder of Convertible Subordinated Notes to be redeemed at his or her registered
address. Convertible Subordinated Notes in denominations larger than $1,000 may
be redeemed in part but only in whole multiples of $1,000. In the event of a
redemption of less than all of the Convertible Subordinated Notes, the
Convertible Subordinated Notes will be chosen for redemption by the Trustee by
lot or pro rata or, if required, in compliance with the requirements of the
principal national securities exchange, if any, on which the Convertible
Subordinated Notes are listed. On and after the redemption date interest ceases
to accrue on Convertible Subordinated Notes or portions of them called for
redemption (unless the Company defaults in the payment of the redemption price).
If this Convertible Subordinated Note is redeemed subsequent to a record date
with respect to any interest payment date specified above and on or prior to
such interest payment date, then any accrued interest will be paid to the person
in whose name this Convertible Subordinated Note is registered at the close of
business on such record date.

     7. CHANGE OF CONTROL. Upon a Change of Control, the Company shall make a
Change of Control Offer to purchase all outstanding securities at a price equal
to 101% of the aggregate principal amount of the Convertible Subordinated Notes,
plus accrued and unpaid interest to the date of purchase, such offer to be made
as provided in the Indenture. To accept the Change of Control Offer, the holder
hereof must comply with the terms thereof, including surrendering this
Convertible Subordinated Note, with the "Option of Holder to Elect Purchase"
portion hereof completed, to the Company, a depositary, if appointed by the
Company, or a Paying Agent, at the address specified in the notice of the Change
of Control Offer mailed to holders as provided in the Indenture, prior to
termination of the Change of Control Offer.

                                      A-3
<PAGE>
 
     8. SUBORDINATION. To the extent set forth in Article 11 of the Indenture
the Convertible Subordinated Notes are subordinated to Senior Indebtedness.
Senior Indebtedness shall not include (a) any indebtedness of the Company to any
of its subsidiaries, (b) Capitalized Lease Obligations, (c) indebtedness or
other obligations in respect of the Pooling and Servicing Agreement, (d) the
Company's 9.25% Subordinated Debentures due 2017 and its 7% Convertible
Subordinated Debentures due 2012, and (e) with respect to an obligation relating
to the deferred purchase price of property or services, any advances, deposits,
partial or progress payments, payables, unpaid wages and related employee
obligations, trade accounts and accrued liabilities. To the extent provided in
the Indenture, Senior Indebtedness must be paid before the Convertible
Subordinated Notes may be paid. The Company agrees, and each holder by accepting
a Convertible Subordinated Note agrees, to the subordination and authorizes the
Trustee to give it effect.

     9. DENOMINATIONS, TRANSFER, EXCHANGE. The Convertible Subordinated Notes
are in registered form without coupons in denominations of $1,000 and integral
multiples of $1,000. The transfer of Convertible Subordinated Notes may be
registered and Convertible Subordinated Notes may be exchanged as provided in
the Indenture. As a condition of transfer, the Registrar 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 Registrar need not exchange or register the
transfer of any Convertible Subordinated Note or portion of a Convertible
Subordinated Note selected for redemption. Also, it need not exchange or
register the transfer of any Convertible Subordinated Note for a period of 15
days before a selection of Convertible Subordinated Notes to be redeemed.

     10. PERSONS DEEMED OWNERS. The registered holder of a Convertible
Subordinated Note may be treated as its owner for all purposes.

     11. AMENDMENTS AND WAIVERS. Subject to certain exceptions, the Indenture or
the Convertible Subordinated Notes may be amended with the consent of the
holders of at least a majority in principal amount of the then outstanding
Convertible Subordinated Notes and any existing default may be waived with the
consent of the holders of a majority in principal amount of the then outstanding
Convertible Subordinated Notes. Without the consent of any holder, the Indenture
or the Convertible Subordinated Notes may be amended to: add to the covenants of
the Company for the benefit of the holders of Convertible Subordinated Notes;
surrender any right or power conferred upon the Company; provide for conversion
rights of holders of Convertible Subordinated Notes in the event of
consolidation, merger or sale of all or substantially all of the assets of the
Company; evidence the succession of another person to the Company and the
assumption by such successor of the covenants and obligations of the Company
thereunder and in the Convertible Subordinated Notes as permitted by the
Indenture; reduce the Conversion Price, provided that such reduction will not
adversely affect the interest of holders of Convertible Subordinated Notes in
any material respect; cure any ambiguity or correct or supplement any defective
provision contained in the Indenture, or make any other change in the provisions
of the Indenture which the Company and the Trustee may deem

                                      A-4
<PAGE>
 
necessary or desirable and which will not adversely affect the interest of the
holders of Convertible Subordinated Notes.

     12. DEFAULTS AND REMEDIES. An Event of Default is: default for 30 days in
payment of interest on the Convertible Subordinated Notes; default in payment of
principal of or premium, if any, on the Convertible Subordinated Notes; failure
by the Company to comply with certain covenants of the Indenture upon the
receipt of written notice of such default as set forth in the Indenture; failure
by the Company for 60 days after notice to it to comply with any of its other
agreements in the Indenture or the Convertible Subordinated Notes; certain
defaults under and accelerations prior to maturity of certain indebtedness;
certain final judgments which remain undischarged; and certain events of
bankruptcy or insolvency. If an Event of Default occurs and is continuing, the
Trustee or the holders of at least 25% in principal amount of the then
outstanding Convertible Subordinated Notes may declare all the Convertible
Subordinated Notes to be due and payable immediately, except that in the case of
an Event of Default arising from certain events of bankruptcy or insolvency, all
outstanding Convertible Subordinated Notes become due and payable without
further action or notice. Holders may not enforce the Indenture or the
Convertible Subordinated Notes except as provided in the Indenture. The Trustee
may require an indemnity satisfactory to it before it enforces the Indenture or
the Convertible Subordinated Notes. Subject to certain limitations, holders of a
majority in principal amount of the then outstanding Convertible Subordinated
Notes may direct the Trustee in its exercise of any trust or power. The Trustee
may withhold from holders notice of any continuing default (except a default in
payment of principal or interest) if it determines that withholding notice is in
their interests. The Company must furnish quarterly compliance certificates to
the Trustee.

     13. TRUSTEE DEALINGS WITH THE COMPANY. The Trustee or any of its
Affiliates, in their individual or any other capacities, may make or continue
loans to or guaranteed by, 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 Trustee.

     14. NO RECOURSE AGAINST OTHERS. No director, officer, employee or
stockholder, as such, of the Company shall have any liability for any
obligations of the Company under the Convertible Subordinated Notes 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 Convertible
Subordinated Note waives and releases all such liability. The waiver and release
are part of the consideration for the Convertible Subordinated Notes.

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

     16. ABBREVIATIONS. Customary abbreviations may be used in the name of a
holder or an assignee, such as: TEN CO = 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.

     17. CONVERSIONS. Subject to and upon compliance with the provisions of the
Indenture, the registered holder of this Note has the right, at its option, at
any time or prior to the close of business on May 15, 2004 (or in case this
Convertible Subordinated Note or any portion hereof shall be called for
redemption prior to such date, then on or prior to the close of business on the
date fixed for redemption), to convert the principal amount hereof, or any
portion of such principal amount which is $1,000 or an integral multiple
thereof, into that number of fully paid and nonassessable whole shares of common
stock of the Company ("Common Stock") obtained by dividing the principal amount
of the Convertible Subordinated Note or portion thereof to be converted by the
conversion price of $10.35 per share, or the conversion price as adjusted from
time to time as provided in the Indenture, upon surrender of this Convertible
Subordinated Note to the Company at the office or agency maintained for such
purpose in New York, New York (and at such other offices or agencies designated
for such purpose by the Company), accompanied by written notice of conversion
duly executed and (if the shares of Common Stock to be issued on conversion are
to be issued in any name other than that of the registered holder of this
Convertible Subordinated Note) by instruments of transfer, in form satisfactory
to the Company, duly executed by the registered holder or its duly authorized
attorney and, in case such surrender shall be made during the period starting
after the close of business on the Regular Record Date immediately preceding any
Interest Payment Date through the close of business on such Interest Payment
Date (unless this Note or the portion thereof being converted is subject to
redemption on a redemption date in that period), also accompanied by payment in
funds acceptable to the Company of an amount equal to the interest otherwise
payable on such Interest Payment Date on the principal amount of this Note then
being converted. Subject to the aforesaid requirement for a payment in the event
of conversion after the close of business on a Regular Record Date immediately
preceding an Interest Payment Date, no payment or adjustment shall be made on
conversion for interest accrued hereon or for dividends on Common Stock
delivered on conversion. The right to convert this Note is subject to the
provisions of the Indenture relating to conversion rights in the case of certain
consolidations, mergers, or sales or transfers of substantially all the
Company's assets.

     The Company shall not issue fractional shares or scrip representing
fractions of shares of Common Stock upon any such conversion, but shall make an
adjustment therefor in cash on the basis of the then current market value of
such fractional interest as provided in the Indenture.

     The Company will furnish to any holder upon written request and without
charge a copy of the Indenture. Requests may be made to: General Counsel, Rohr,
Inc., 850 Lagoon Drive, Chula Vista, California 91910.

          (a) the Agent shall have received counterparts of this Sixth Amendment
     executed by the Borrower and the Majority Lenders or, as to any such
     Lender, advice satisfactory to the Agent that such Lender has executed
     counterparts of this Sixth Amendment,

          (b) the definition of "Consolidated Net Income Available for Fixed

A Notes, and each B Note outstanding on the date hereof, shall remain in full
force and effect and are hereby ratified and confirmed.

          (c) The execution, delivery and effectiveness of this Sixth Amendment

separate counterparts, each of which when so executed and delivered shall be
deemed to be an original and all of which taken together shall constitute but

    Note:

    The assumed conversion of the Company's convertible debentures were anti-
    dilutive or did not have a materially dilutive impact on earnings per share,
    hence only primary earnings per share is presented in the Company's
    Consolidated Financial Statements.
