Item 2.  Acquisition or Disposition of Assets.
         -------------------------------------

     On July 28, 1999, Advanstar Communications Inc. (the "Company"), a wholly-
     owned subsidiary of Advanstar, Inc., completed its acquisition of certain
     assets of Larkin-Pluznick-Larkin, LLC, and LPL/Style Group, LLC, each a
     limited liability company organized under the laws of Delaware
     (collectively, "Larkin").  Larkin, headquartered in Newton,
     Massachusetts, is a producer, promoter and provider of trade shows for
     the fashion industry.  The Company intends to integrate the acquired
     businesses of Larkin with the Company's existing operations.

     The aggregate purchase price for the transaction was approximately
     $133.0 million in cash.  The source of the funds used in this acquisition
     was the Company's existing credit facility, (as amended concurrently with
     the acquisition to provide additional borrowing capacity to finance the
     acquisition) and this acquisition will be accounted for using the
     purchase method of accounting.  The purchase price and terms for the
     transaction were determined in arms-length negotiations.

     This Current Report on Form 8-K contains forward-looking statements made
     pursuant to the safe harbor provisions of the Private Securities Litigation
     Reform Act of 1995. Investors are cautioned not to place undue reliance on
     these forward-looking statements, including statements about plans and

                       REPORT OF INDEPENDENT ACCOUNTANTS



To the Board of Directors of
Larkin-Pluznick-Larkin, Inc.:

In our opinion, the accompanying balance sheet and the related statements of
earnings and comprehensive income, changes in owners' net investment, and cash
flows present fairly, in all material respects, the financial position of The
Tradeshow Business of Larkin-Pluznick-Larkin, Inc. (the "Business") at February
28, 1999, and the results of its operations and its cash flows for the year then
ended, in conformity with generally accepted accounting principles.  These
financial statements are the responsibility of the Business's management; our
responsibility is to express an opinion on these financial statements based on
our audit.  We conducted our audit of these statements in accordance with
generally accepted auditing standards which require that we plan and perform the
audit to obtain reasonable assurance about whether the financial statements are
free of material misstatement.  An audit includes examining, on a test basis,
evidence supporting the amounts and disclosures in the financial statements,
assessing the accounting principles used and significant estimates made by
management, and evaluating the overall financial statement presentation.  We
believe that our audit provides a reasonable basis for the opinion expressed
above.

These financial statements reflect The Tradeshow Business of Larkin-Pluznick-
Larkin, Inc., which is a component of Larkin-Pluznick-Larkin, Inc. (see Footnote
A).  As disclosed in Footnote I, on May 27, 1999, Larkin-Pluznick-Larkin, Inc.
signed a letter of intent to sell substantially all of the assets of the
Business.

                           THE TRADESHOW BUSINESS OF
                         LARKIN-PLUZNICK-LARKIN, INC.

                         NOTES TO FINANCIAL STATEMENTS

A. Nature of Business:
   ------------------

   The Tradeshow Business of Larkin-Pluznick-Larkin, Inc. (the "Business") is a
   producer of various trade shows and a related publication that pertain to the
   women's clothing, children's clothing and fabric industries.  These events
   take place in the United States.  The Business has been carved out from its
   parent, Larkin-Pluznick-Larkin, Inc. (the "Company").  The Company's
   consolidated financial statements include the Business, two additional
   publications ("School Band and Orchestra" and "Musical Merchandise Review")
   and three wholly-owned subsidiaries (EasySoft, Clearlink and TSNN).  These
   financial statements of  the Business reflect the financial position, results
   of operations and cash flows of the tradeshow business and its related
   publication (Accent).


B. Summary of Accounting Policies:
   ------------------------------

   A summary of significant accounting policies applied in the preparation of
   the accompanying financial statements follows:

     Basis of Presentation

     The financial statements do not include the assets, liabilities, owners'
     net investment, results of operations and cash flows applicable to two
     publications ("School Band and Orchestra" and "Musical Merchandise Review")
     that are being retained by the current owners.  In addition, the financial
     statements do not include the Company's three wholly-owned subsidiaries.

     The statement of operations does not include certain costs and expenses
     allocated to the two publications and the three wholly-owned subsidiaries
     being retained by the current owners.  These costs and expenses have been
     allocated based on management's estimates of the cost of services provided
     to the publications by the Company.  Such costs include production costs
     and general and administrative expenses.  Such allocations are based on
     either a direct pass through or a percentage of total costs for the
     services provided based on factors such as headcount, square footage and
     sales.  Management believes that these allocations are based on assumptions
     that are reasonable under the circumstances.  However, these allocations
     and estimates are not necessarily indicative of the costs and expenses
     which would have resulted if the publications had been operated as a
     separate entity.

     The Company's three wholly-owned subsidiaries are operated as separate,
     independent entities of The Tradeshow Business of Larkin-Pluznick-Larkin,
     Inc. and the two publications.  Accordingly, the Company's costs and
     expenses were not shared with the three subsidiaries and did not require
     allocations in the preparation of the financial statements of the Business.
     The financial statements of the Business are derived from the historic
     books and records of the Company.

     The Company and the Business have no external borrowings.  An allocation
     has been made of the interest expense incurred in connection with the stock
     redemption described in Note H based on the relative sales of the Business
     compared to the sales of the Company.  The Business's

                           THE TRADESHOW BUSINESS OF
                         LARKIN-PLUZNICK-LARKIN, INC.

                   NOTES TO FINANCIAL STATEMENTS, CONTINUED

     balance sheet included 100% of the activity related to the owners' stock
     redemption and dividend distributions and accruals. The owners' net
     investment has been reduced by the net assets of the two publications and
     the three wholly-owned subsidiaries of the Company that are being retained
     by the current owners.

     Cash and Cash Equivalents

     For the purposes of the statement of cash flows, the Business considers all
     highly liquid debt instruments purchased with a maturity of three months or
     less at time of purchase to be cash equivalents.

     Available-for-Sale Securities

     Investments are stated at fair value as reported by the investment
     custodians.  All investments are designated as available-for-sale in
     accordance with the provisions of Statement of Financial Accounting
     Standards No. 115, "Accounting for Certain Investments in Debt and Equity
     Securities," and, as such, unrealized gains and losses are reported as a
     separate component of comprehensive income and realized gains and losses
     are included in the statement of earnings.

     The Business may experience fluctuations in the realized and unrealized
     gains and losses on investments from one year to the next due to trends in
     interest rates.

     Risk and Uncertainties

     The Business maintains its cash in bank deposit accounts which, at times,
     may exceed federally insured limits.  Also, certain cash and available-for-
     sale investment amounts are held in an institutional account managed by a
     large money management firm.  The Business believes it is not exposed to
     any significant credit risk on cash and cash equivalents or available-for-
     sale investments.

     Use of Estimates

     The preparation of financial statements in conformity with generally
     accepted accounting principles requires management to make estimates and
     assumptions that affect the reported amounts of assets and contingent
     liabilities at the date of the financial statements and the reported
     amounts of revenues and expenses during the reporting periods.  Actual
     results could differ from those estimates.

     Prepaid Expenses

     Prepaid expenses consist primarily of direct costs relating to future shows
     including deposits, marketing, insurance and postage.

                   NOTES TO FINANCIAL STATEMENTS, CONTINUED

     Property and Equipment

     Property and equipment are stated at cost.  Upon retirement or disposition,
     the cost of the assets disposed of and the related accumulated depreciation
     are removed from the accounts and any resulting gain or loss is included in
     the determination of net earnings.

     Depreciation

     Depreciation is computed over the estimated useful lives using a
     combination of straight-line and accelerated methods.  The estimated useful
     lives of property and equipment are as follows:

                                                  Years
                                                  ------

       Data processing and printing equipment       5 - 7
       Capitalized software                         5
       Office furniture and equipment               5 - 7
       Leasehold improvements                    31.5 - 39

     Intangible Assets

     Intangible assets consist principally of goodwill and trademarks and are
     amortized on a straight-line basis over periods of 4 to 10 years.

     Impairment of Long-Lived Assets

     The Business reserves for the impairment of long-lived and certain
     identifiable intangibles whenever events or changes in circumstances
     indicate that the carrying amount of an asset may not be recoverable.  All
     impairment losses would be recognized when estimated future cash flows
     expected to result from the use of the asset and its eventual disposition
     is less than its carrying amount.  The Business has not identified any such
     impairment losses.

     Revenue Recognition and Deferred Income

     The Business recognizes show revenue upon completion of a show and
     recognizes publication income when the issue is mailed.  Deferred income
     principally represents advance payments received, net of discounts, for
     booth space in trade shows to be held in the next fiscal year.

     Comprehensive Income

     In 1999, the Business adopted Statement of Financial Accounting Standards
     No. 130 ("SFAS 130"), "Reporting Comprehensive Income."  This statement
     established rules for reporting comprehensive income and its components.
     Comprehensive income consists of net income and unrealized appreciation
     (depreciation) on available-for-sale securities and is presented in the
     consolidated statements of earnings and comprehensive income.  The adoption
     of SFAS No. 130 had no impact on net earnings or owners' net investment.

     Recent Accounting Pronouncements

     In June 1997, the Financial Accounting Standards Board issued SFAS No. 131,
     "Disclosures about Segments of an Enterprise and Related Information."
     This statement establishes standards for the way companies report
     information about operating segments in annual financial statements.  It
     also establishes standards for related disclosures about products and
     services, geographic areas and major customers.  The Business has
     determined that it does not have any separately reportable business
     segments as of February 28, 1999.

     In March 1998, the American Institute of Certified Public Accountants
     issued Statement of Position ("SOP") No. 98-1, "Software for Internal Use,"
     which provides guidance on accounting for the cost of computer software
     developed or obtained for internal use.  SOP No. 98-1 is effective for
     financial statements for fiscal years beginning after December 15, 1998.
     The Business does not expect that the adoption of SOP No. 98-1 will have a
     material impact on its financial statements.

     In June 1998, the Financial Accounting Standards Board issued Statement No.
     133 ("SFAS 133"), "Accounting for Derivative Instruments and Hedging
     Activities," which requires that all derivative instruments be recorded on
     the balance sheet at their fair value.  Changes in the fair value of
     derivatives are recorded each period in current earnings or other
     comprehensive income, depending on whether a derivative is designated as
     part of a hedge transaction.  Management of the Business does not expect a
     material impact on its results of operations or financial position
     resulting from the adoption of SFAS 133 because the Business currently does
     not hold derivative instruments.


C.  Available-for-Sale Securities:
    -----------------------------

    The Business accounts for its short-term investments in accordance with the
    provisions of Statement of Financial Accounting Standards No. 115 ("SFAS
    115"), "Accounting for Certain Investments in Debt and Equity Securities."
    At February 28, 1999, the cost of available-for-sale securities, which
    principally consist of municipal bonds and equities, was $2,335,024.  The
    maturities of available-for-sale securities held at February 28, 1999, are
    approximately $177,000 within one year, $372,000 from one to five years,
    $400,000 from five to ten years, and $1,125,000 greater than ten years. All
    available-for-sale investments are classified as current assets consistent
    with their use.

D.  Intangible Assets:
    -----------------

    On January 17, 1996 the Company, on behalf of the Business, acquired the
    trademark, "TAG, the accessory and garment leather show" ("TAG"), denoting a
    trade show sponsored by Leather Industries of America, Inc.  The purchase
    price for TAG consists of $10,000 in cash plus a percentage of gross
    deposits and fees.

    Capitalized costs for the TAG purchase at February 28, 1999 include the
    following:


     Trademark                                      $10,000
     Less accumulated amortization                   (6,666)
                                                    -------

     Net intangible asset                           $ 3,334
                                                    =======

    On July 30, 1998 the Company, on behalf of the Business, acquired the assets
    of Style Industrie ("Style") for $1,400,000. Additionally, the asset
    purchase agreement provided for the Company to pay the following amounts to
    the former owner of Style: (i) one-third of revenue from the September 1998
    show, (ii) $150,000 if the September 1998 show revenue exceeded $1,500,000,
    (iii) one-third of revenue from the February 1999 show, and (iv) $150,000 if
    the February 1999 show revenue exceeded $1,500,000. In total, the Company
    made additional payments of $1,586,442 related to the purchase of Style.
    Therefore, the total purchase price for Style was $2,986,442 which was
    allocated primarily to goodwill, as well as to a covenant not to compete and
    intellectual property.


E.  Federal and State Income Taxes:
    ------------------------------

    The Business is not a separate taxable entity for federal, state or local
    income tax purposes and its taxable income is included in the consolidated
    Larkin-Pluznick-Larkin, Inc. tax returns. The Business accounts for income
    taxes under the separate return method in accordance with Statement of
    Financial Accounting Standards No. 109 ("SFAS 109"), "Accounting for Income
    Taxes."

    Pursuant to an election under Subchapter S of the Internal Revenue Code, net
    earnings pass through to the Company's stockholders for federal tax
    purposes. The financial statements of the Business are prepared as if the
    Business is also a Subchapter S. Accordingly, no provisions have been made
    for federal income taxes in the financial statements of the Business. For
    state income tax purposes, the Company is taxed at the corporate level in
    California and New York City and at the corporate and individual levels in
    Massachusetts and New York State. This Business has prepared its provision
    using the same assumptions for state income tax purposes.

    The provision for income taxes is determined in accordance with the
    provisions of SFAS 109, which requires recognition of deferred tax
    liabilities and assets for the expected future tax consequences of events
    that have been included in the financial statements or tax returns. Under
    this method, deferred tax liabilities and assets are determined based on the
    difference between the financial statement and tax bases of assets and
    liabilities using enacted tax rates in effect from the year in which the
    differences are expected to reverse.

F.  Commitments and Contingency:
    ---------------------------

    The Company, on behalf of the Business, has contracted to lease a convention
    center on dates specified for future shows. The future liability at February
    28, 1999, for these leases through October 1999, was $1,308,020, of which
    $687,084 was on deposit as of February 28, 1999. Lease payments are payable
    regardless of whether or not the convention space is used during the lease
    period. Rent expense related to the convention center was $1,773,360 for the
    year ended February 28, 1999.

    The Company, on behalf of the Business, leases office space in Newton,
    Massachusetts, New York City, and Los Angeles. These leases expire on
    various dates through December 2002. Rent expense for office space,
    including lease escalation expenses, was $709,363 for the year ended
    February 28, 1999.

    Total minimum rental payments and lease commitments, including convention
    space, are as follows:

                             Convention         Office

G.  Employee Benefit Plans:
    ----------------------

    The Company maintains a 401(k) Profit Sharing and Savings Plan (the "Plan"),
    which is a defined contribution plan with a 401(k) provision. Employees of
    the Business participate in the Company's Plan. The Plan is a voluntary
    program in which employees who meet certain requirements can contribute up
    to 15% of their gross annual salary subject to certain IRS limitations. The
    Business will match 25% of the first 8% of its employee contributions. In
    addition, the Business, at its option, may make a discretionary
    contribution. The Business did make discretionary contributions for its
    employees of approximately $102,000 in 1999, and total pension expense under
    the Plan was approximately $147,000 in 1999 for the Business.

H.  Stock Redemption:
    ----------------

    On March 1, 1998, the Company redeemed 13,608 shares of non-voting common
    stock from three of the seven shareholders of the Company. This transaction
    leaves the remaining number of shares outstanding at 14,392, which are owned
    equally by the seven shareholders. In return for the redeemed shares, the
    Company issued five-year notes totaling $4,858,056 and bearing interest of
    7% per year to the three shareholders. The notes require interest to be paid
    each year beginning in February 1999 and the principal to be paid in
    February 2003, however, principal payments can be made at any time during
    the five year period without a penalty. During 1999, the Company made
    principal and interest payments to the three shareholders in the amounts of
    $1,271,873 and $305,549, respectively, leaving a remaining balance of
    $3,586,183. This amount is presented as payable to owners on the balance
    sheet of the Business. In order to partially fund these payments, three
    other shareholders of the Company loaned money to the Company. This amount
    of $622,466 has been included in the payable to related parties on the
    balance sheet of the Business.


I.  Subsequent Events:
    -----------------

    On May 27, 1999, the Company signed a letter of intent to sell substantially
    all of the assets of the Business to Advanstar, Inc. for $140 million.

                         UNAUDITED PRO FORMA COMBINED
                             FINANCIAL INFORMATION

     The unaudited pro forma combined balance sheet as of June 30, 1999 includes
the historical accounts of Advanstar at June 30, 1999 and Larkin at May 31, 1999
and gives effect to the Larkin acquisition as if it had occurred on June 30,
1999. The unaudited pro forma combined statement of operations for the year
ended December 31, 1998 includes the historical operations of Advanstar and
gives effect to the Larkin acquisition as if it had occurred on January 1, 1998.
The unaudited pro forma combined statement of operations for the six months
ended June 30, 1999 includes the historical operations of Advanstar and gives
effect to the Larkin acquisition as if it had occurred on January 1, 1999.

     The unaudited pro forma combined financial information has been prepared by
the management of Advanstar and has been derived from the historical statements
of operations and balance sheets of Advanstar and Larkin. We have accounted for
the Larkin acquisition under the purchase method of accounting.

     On July 28, 1999 we acquired the trade show business and certain other
assets from Larkin-Pluznick-Larkin, Inc., for cash consideration of
approximately $127.0 million and two promissory notes in the aggregate of
approximately $6.0 million..

     The unaudited pro forma combined financial information is not designed to
represent and does not represent what Advanstar's results of operations actually
would have been had the aforementioned transaction been completed as of the
dates indicated, or to project Advanstar's results of operations for any future
period. The Pro Forma Adjustments are based on available historical financial
information and should be read in conjunction with the financial statements and
accompanying notes thereto.

     When you read the unaudited combined pro forma balance sheet as of June 30,
1999 presented in the table below, please consider the following about the pro
forma adjustments:

     .  Cash and cash equivalents, available for sale securities and property,
        plant & equipment represent the elimination of Larkin's historical
        balances which were excluded from the assets acquired;

     .  goodwill and other intangible assets  represent the preliminary
        allocation of the aggregate purchase price of the Larkin acquisition
        as follows (in millions):

        Historical net book value of net assets acquired         $    650
                                                                 --------
        Excess purchase prices over net liabilities assumed
          (allocated to goodwill and intangible assets            132,350
        Aggregate purchase price                                 $133,000
                                                                 ========

        The excess purchase price over net liabilities assumed is partially
        offset by the elimination of Larkin's historical goodwill and other
        intangible assets.

        Goodwill and intangible assets will be amortized on a straight line
        basis over 23 years.  After giving effect to the pro forma adjustments,
        at June 30, 1999, goodwill represented 79.3% of total pro forma assets;

     .  accounts payable, payable to related parties and income taxes payable
        represent the elimination of Larkin's historical balances which were
        excluded from the liabilities assumed;

     .  long-term debt represents incremental borrowings to finance the Larkin
        acquisition;

     .  common stock, retained earnings and accumulated other comprehensive
        income represent  the elimination of the historical capital accounts
        and accumulated earnings of Larkin.

     When you read the unaudited combined pro forma statement of operations data
for the year ended  December 31, 1998 presented in the table below, please
consider that the results of operations of Larkin represent the results for the
12 months ended February 28, 1999.

     When you read the table below for the year ended December 31, 1998, you
should consider the following pro forma adjustments:

     .  gross profit represents the elimination of $0.3 million of show
        contractor costs in connection with the Larkin acquisition.  These
        costs will be eliminated as a result of the acquisition.

     .  general and administrative expenses represent the elimination of
        (1)$6.0 million of shareholder payments to certain shareholders of
        Larkin-Pluznik-Larkin, Inc., that will not recur following our
        acquisition of Larkin, (2) $0.9 million of other non-recurring costs
        related to our acquisition of Larkin;

     .  depreciation and amortization represent the incremental amortization
        of goodwill arising from the Larkin acquisition; we are amortizing
        this goodwill on a straight line basis over 23 years;

     .  interest income (expense), net represents incremental interest expense
        on borrowing under our credit facility to finance the Larkin
        acquisition as if it had been completed on January 1, 1998.

     When reading the other financial data presented in the table below, you
should also consider the following:

     .  we define EBITDA as operating income plus amortization and
        depreciation;

     .  our calculation of EBITDA may not be comparable to other companies'
        calculations;

     .  EBITDA does not represent, and should not be considered, an
        alternative to net income or cash flow from operations; and

     .  EBITDA does not take into account our working capital requirements,
        debt service requirements and other commitments and does not
        necessarily indicate amounts that may be available to us for
        discretionary uses.

We have included this data in the table below because we believe that EBITDA
provides useful information regarding our ability to service and/or incur
indebtedness. Our lenders have indicated that the amount of indebtedness we will
be permitted to incur will be based, in part, on our EBITDA.

     When you read the unaudited combined pro forma statement of operations for
the six month period ended June 30, 1999 presented in the table below, please
consider that Larkin's results of operations represent results of operations for
the six months ended May 31, 1999. The three months period ended February 28,
1999 included in the six month period ended May 31, 1999 are also included in
the unaudited pro forma combined statement of operations for the year ended
December 31, 1998.

     When you read the table below for the six month period ended June 30, 1999,
you should consider the following about the pro forma adjustments:

     .  gross profit represents the elimination of $0.2 million of show
        contractor costs in connection with the Larkin acquisition. These
        costs will be eliminated as a result of the acquisition;

     .  general and administrative expenses represent the elimination of (1)
        $4.4 million of shareholder payments to certain shareholders of Larkin-
        Pluznik-Larkin, Inc., that will not recur following our acquisition of
        Larkin, (2) $0.7 million of other non-recurring costs related to our
        acquisition of Larkin;

     .  depreciation and amortization represent the incremental amortization of
        goodwill arising from the Larkin acquisition; we are amortizing this
        goodwill on a straight line basis over 23 years;

     .  interest income (expense), net represents incremental interest expense
        on borrowing under our credit facility to finance the Larkin
        acquisition as if it had been completed on January 1, 1999.

     When reading the other financial data presented in the table below, you
should also consider the following:

     .  we define EBITDA as operating income plus amortization and depreciation;

     .  our calculation of EBITDA may not be comparable to other companies'
        calculations;

     .  EBITDA does not represent, and should not be considered, an alternative

     .  EBITDA does not take into account our working capital requirements, debt

          assume no liabilities or obligations relating to the Events, the
          Publication, the Ancillary Products, the Business, the Assets, Seller
          or the Owners.  Without limitation of the foregoing, Buyer shall
          assume no liability or obligation for (i) Taxes (as hereinafter
          defined) of Seller and the Owners for any period, or imposed in
          connection with the Events, the Publication, the Ancillary Products,
          the Business or the Assets for any periods ending prior to the Closing
          Date, (ii) any liability of any of the foregoing persons for the
          unpaid Taxes of any person under Treasury Regulation Section 1.1502-6
          (or any similar provision of state, local or foreign law) or as a
          transferee or successor, by contract or otherwise, and (iii) except as
          provided in Section 9.3, any Taxes imposed upon Seller or any of the
          Owners in connection with the transactions set forth in this Agreement
          (the liabilities referred to in (i), (ii) and (iii) above are referred
          to herein collectively as "Tax Liabilities").  All such liabilities
          and obligations (including, without limitation, indebtedness, Tax
          Liabilities, accounts payable, obligations to employees, contractual
          obligations and all Litigation, whether or not listed on Schedule
                                                                   --------
          4.5), fixed or contingent, known or unknown, which were incurred by
          ---
          Seller or the Owners or arose from the operation of the Business prior
          to the Closing Date (as hereinafter defined) are and remain the
          liabilities and obligations of Seller or the Owners, as the case may
          be.  Seller and the Owners hereby covenant to discharge in full in a
          due and timely manner all such liabilities and obligations; provided
          that nothing contained herein shall prevent Seller from contesting any
          such liabilities or obligations in good faith.  Notwithstanding the
          foregoing, except to the extent that any such liability or obligation
          represents a Tax Liability, Buyer shall assume the following
          liabilities and obligations of Seller at the Closing (collectively,
          the "Assumed Liabilities"):

                                      -5-
<PAGE>

          (i)   the obligation for Seller's performance after the Closing Date
                under the Assumed Contracts;

          (ii)  accounts payable, due to unaffiliated third parties, incurred by
                Seller in the ordinary course prior to the Closing Date, in
                respect to Future Events, Future Publications and/or Future
                Ancillary Products;

          (iii) the Closing Liabilities (as hereinafter defined); and

          (iv)  any and all obligations and liabilities incurred by Buyer
                relating to the ownership of the Assets or the operation of the
                Business by Buyer from and after the Closing Date.

     (b)  Notwithstanding anything to the contrary contained in Section 1.3(a),
          neither this Agreement nor any other agreement referenced herein shall
          constitute an assignment of any contract or right or benefit arising
          thereunder if such assignment would constitute a breach or otherwise
          adversely affect the rights of Buyer thereunder.  In the event that
          Seller does not obtain any required consent or waiver for the transfer
          of any Assumed Contract to Buyer prior to Closing, Seller shall
          continue to use reasonable efforts to obtain such consent or waiver.
          Seller shall keep such Assumed Contract in effect for the benefit of
          Buyer until such consent or waiver is obtained at no additional
          expense to Seller or any of the Owners.

                               PAYMENT TO SELLER

2.1  Consideration for the Assets.  Subject to the terms and conditions of this
     ----------------------------
     Agreement, in consideration of the sale, assignment, transfer and delivery
     of the Assets to Buyer, for the services to be rendered to Buyer pursuant
     to the Consulting Agreements (as hereinafter defined) and for the covenants
     of Seller and the Owners contained in Article IX, Buyer shall pay to
     Seller, on behalf of the Seller and the Owners, the aggregate amount of (x)
     if the Closing occurs on or before July 30, 1999, One Hundred Thirty-Three
     Million Dollars ($133,000,000), (y) if the Closing occurs after July 30,
     1999 but before August 8, 1999, One Hundred Thirty-One Million Three
     Hundred Fifty Thousand Dollars ($131,350,000) and (z) if the Closing occurs
     on or after August 8, 1999, One Hundred Thirty-One Million Dollars
     ($131,000,000), in any case as adjusted by Section 2.2 (the "Purchase
     Price"); provided, however, that if the failure of the Closing to occur has
              --------  -------
     been caused by or resulted from a breach by Buyer of any of its
     representations, warranties or agreements contained in this Agreement, the
     Purchase Price shall equal One Hundred Thirty-Three Million Dollars
     ($133,000,000) as adjusted by Section 2.2.  The Purchase Price shall be
     paid as follows: (a) the applicable amount set forth in the immediately
     preceding sentence less $6,000,000 (the "Closing Payment") shall be paid at
     the Closing to Seller by wire transfer of immediately available funds to
     the account designated on Schedule 2.1(a); and (b) the remaining $6,000,000
                               ---------------
     shall be payable in two installments, one of $2,000,000

                                      -6-
<PAGE>

     payable on the first anniversary of the Closing Date and one of $4,000,000
     payable on the second anniversary of the Closing Date, which installments
     shall be represented by promissory notes (the "Notes") of Buyer in the
     aggregate principal amount of $6,000,000 in the forms of Exhibit A-1 and A-
     2, to be reduced by Buyer to set-off sums owed by Seller to Buyer under the
     indemnification provisions of Article VIII of the Agreement. At the
     Closing, Buyer and Seller shall also execute and deliver an Escrow
     Agreement (as hereinafter defined) establishing an escrow account at The
     Chase Manhattan Bank (the "Escrow Agent"). Buyer shall also cause to be
     delivered to the Seller, on behalf of Seller and the Owners, an irrevocable
     standby letter of credit from The Chase Manhattan Bank in substantially the
     form of Exhibit A-3 hereof (the "Letter of Credit") providing for a draw-
     down only in the event of a default by Buyer under the Notes, with any
     draw-down payment to be made by wire transfer of immediately available
     funds in accordance with the terms of the Letter of Credit either directly
     to Seller or to an escrow account created by the Escrow Agreement.

2.2  Adjustment to the Purchase Price.
     --------------------------------

     (a)  Attached hereto as Schedule 2.2 is a preliminary statement (the
                             ------------
          "Preliminary Closing Statement") of the amounts of certain Assets and
          Assumed Liabilities of Seller as of the date hereof.  The Preliminary
          Closing Statement includes only the following items: (i) prepaid
          expenses of the Business, (ii) accounts receivable of the Business
          described in Section 1.1(u) that were generated on or after April 28,

          (iii) deferred revenue, accounts payable and other current liabilities
          (including, without limitation, customer credits, accrued vacation and
          sick pay of Seller's employees) of the Business (the "Closing
          Liabilities").  The Closing Liabilities shall not include any Tax
          Liabilities.  Two business days prior to the Closing Date, Seller
          shall provide Buyer with an updated Preliminary Closing Statement (the
          "Updated Closing Statement") which, in Seller's best judgment,
          estimates the amounts of the Closing Assets and the Closing
          Liabilities as of the Closing Date.

     (b)  The "prepaid expenses" included in the Closing Assets (i) shall be
          direct expenses incurred and paid by Seller prior to the Closing Date
          to unaffiliated third parties which inure to the benefit of Buyer from
          and after the Closing Date, including, without limitation, expenses in
          respect to Future Events, Future Publications and/or Future Ancillary
          Products; (ii) shall not include any management fees, salaries, other
          employee compensation or benefits, internal allocations, general
          office expenses or other overheads of the Business, whether incurred
          and/or paid by Seller; and (iii) shall include only those direct
          expenses which have been incurred and paid by Seller in the ordinary
          course of business consistent with Seller's past practice in operating
          the Business.  The accounts receivable included in the Closing Assets
          shall include only those which arose in the ordinary course of
          business.

     (c)  The "deferred revenue" included in the Closing Liabilities (i) shall
          consist of all exhibitor deposits, cancellation and forfeiture
          amounts, contractor commissions

                                      -7-
<PAGE>

          (if any), show and conference registration fees, sponsorship fees,
          advertising revenue, subscription revenue, prepayments and other
          miscellaneous revenue received by Seller as of the effective date of
          such statement in respect to Future Events, Future Publications or
          Future Ancillary Products, (ii) shall include only deferred revenue
          which has been received by Seller in the ordinary course of business
          consistent with Seller's past practice in operating the Business and
          (iii) shall be recorded at fulfillment cost in the case of unfulfilled
          paid subscriptions to the Publication. The "accounts payable" included
          in the Closing Liabilities shall include all unpaid expenses of Seller
          of any nature which are related to Seller's Events, Seller's
          Publications, Seller's Ancillary Products or otherwise related to the
          operation of the Business prior to the effective date of such
          statement. The "other current liabilities" included in the Closing
          Liabilities shall include all outstanding customer credits, accrued
          vacation, sick pay and other current liabilities of the Business as of
          the effective date of such statement.

     (d)  For purposes of this Agreement, the "Preliminary Adjustment" shall be
          the positive or negative, as applicable, amount by which the Closing
          Assets exceed the Closing Liabilities as set forth in the Updated
          Closing Statement.  In the event that the Preliminary Adjustment is a
          positive amount, then the Purchase Price (and, correspondingly, the
          Closing Payment) shall be increased by the amount of the Preliminary
          Adjustment.  In the event that the Preliminary Adjustment is a
          negative amount, then the Purchase Price (and, correspondingly, the
          Closing Payment) shall be decreased by the amount of the Preliminary
          Adjustment.

     (e)  As soon as reasonably practicable after the Closing Date but not later
          than seventy-five (75) days following the Closing Date, Buyer and
          Seller shall jointly establish a definitive statement of Closing
          Assets and Closing Liabilities as of the Closing Date (the "Final
          Closing Statement").  The Final Closing Statement (i) shall include
          only the Closing Assets and the Closing Liabilities, (ii) shall be
          prepared on a basis consistent with and shall follow the format of the
          Preliminary Closing Statement and the Updated Closing Statement, and
          (iii) shall further update the Updated Closing Statement by reflecting
          any changes to the Updated Closing Statement which are necessary as a
          result of disbursements or receipts which were made or received too
          late to be reflected in the Updated Closing Statement, computational
          or other errors which may have been made in preparing the Updated
          Closing Statement, or for any other reason consistent with this
          Agreement.  For purposes of this Agreement, the "Final Adjustment"
          shall be the amount by which the Closing Assets exceed the Closing
          Liabilities as set forth in the Final Closing Statement.

     (f)  In the event that the parties are unable to resolve any dispute
          regarding the preparation of the Final Closing Statement within
          seventy-five (75) days following the Closing Date hereof (or such
          longer period as the parties may hereafter agree), the parties shall
          submit all matters that remain in dispute to Deloitte & Touche, LLP
          or, if such firm is unavailable for any reason, another nationally
          recognized firm of independent public accountants (which firm shall

                                 -8-
<PAGE>

          not be the auditor for any party and shall otherwise be selected by
          mutual agreement of the parties), for accounting arbitration.  The
          parties shall use all reasonable efforts to cause such firm to render
          a decision resolving the matters submitted to it and, thereby,
          establish the amount of the Final Adjustment within thirty (30) days
          following submission.  Judgment may be entered upon the determination
          of such firm in any court having jurisdiction over the party against
          which such determination is to be enforced.  The fees and expenses of
          such firm shall be paid by the party whose calculation of the Final
          Adjustment is further (in dollar amount) from the calculation of the
          Final Adjustment by the firm.  Absent fraud or manifest error, the
          determination of such firm as to the Final Adjustment shall be final.

     (g)  If the Final Adjustment is a greater amount than the Preliminary
          Adjustment, Buyer shall, within ten (10) business days after the date
          of such determination, pay to Seller the amount of such difference by
          wire transfer in immediately available funds.  If Buyer fails to make
          such payment within such ten (10) business day period, (i) such
          payment shall accrue interest from and after such date at the prime
          rate as published in The Wall Street Journal plus two percent (2%) and
          (ii) Buyer shall pay all of Seller's costs of collection (including
          reasonable attorney fees).  If the Final Adjustment is a lesser amount
          than the Preliminary Adjustment, Seller shall, within ten (10)
          business days after the date of such determination, pay to Buyer the
          amount of such difference by wire transfer in immediately available
          funds.  If Seller fails to make such payment within such ten (10)
          business day period, Buyer shall be entitled to set-off the amount of
          such payment against the Notes in accordance with the terms thereof.

2.3  Allocation of the Purchase Price.  The parties acknowledge and agree that
     --------------------------------
     the Purchase Price shall be allocated for all purposes (including, without
     limitation, Tax reporting purposes) as indicated on Schedule 2.3 hereto.
                                                         ------------
     The parties each agree to file IRS Form 8594 and all Tax returns in a
     manner consistent with such allocation and shall use their reasonable best
     efforts to sustain such allocation in any subsequent Tax audit or Tax
     dispute.  Seller and each Owner acknowledge and agree that the
     consideration allocated to the covenants contained in Section 9.10 and the
     Consulting Agreements is not an adequate measure of the damages which would
     be sustained by Buyer as a result of a breach by Seller and/or each Owner
     of their obligations under such covenants and/or agreements, and that such
     allocated consideration shall not under any circumstances be admissible as
     evidence of damages or for any other purpose in any legal or equitable
     proceeding brought by Buyer to enforce such obligations or obtain damages
     in respect of a breach thereof.

     settlement (i) does not require an admission of liability or wrong doing on
     the part of the indemnified party, (ii) does not limit conduct of
     indemnified party's business or impose a future obligation on the
     indemnified party to do or refrain from doing anything and (iii) does not

9.7  Excluded Trademarks. Upon the terms and subject to the conditions set forth

     in this Section 9.7, Seller hereby grants to Buyer a worldwide,
     nonexclusive and nontransferable right and license to use (but not to
     sublicense) the Excluded Trademarks for the three-year period commencing on
     the Closing Date in connection with Buyer's operation of the Business after
     the Closing Date. Buyer's use of the Excluded Trademarks shall be in
     accordance with Seller's reasonable policies and practices regarding
     trademark use as established from time to time by Seller; provided, that
                                                               --------
     Buyer shall be entitled to use the Excluded Trademarks in the manner as
     Seller uses the Excluded Trademarks in the conduct of the Business as the
     same is conducted by Seller on the date of this Agreement; and provided,
                                                                    --------
     further, that Buyer shall not indicate or otherwise suggest, in connection
     -------
     with such use, that Seller owns or operates the Business after the Closing
     Date. Buyer agrees and acknowledges that the Excluded Trademarks, together
     with the goodwill symbolized thereby, is the sole and exclusive property of
     Seller, and that its usage by Buyer shall inure to the benefit of Seller.

                                      -31-

9.8  Bulk Sales Laws.  Buyer hereby waives compliance by Seller with the
     ---------------
     provisions of any bulk sales, bulk transfer or similar laws, and Seller and
     the Owners agree to indemnify and hold Buyer harmless against any and all
     losses, costs, damages, charges or expenses of any nature (including
     reasonable attorney's fees) resulting from Seller's non-compliance with
     such laws, except to the extent that any liability arising as a result of
     such non-compliance relates to any of the Assumed Liabilities.

9.9  Confidential Information.  Seller and the Owners shall ensure that neither
     ------------------------
     Seller nor any Owner shall disclose to any person or entity or use for any
     purpose any trade secrets or confidential or proprietary documents,
     processes, strategic or marketing plans, other strategic or marketing
     information, databases, attendee lists, exhibitor lists, advertiser lists,
     subscriber lists or financial or other information relating to the Business
     and/or the Assets.

9.10 Non-Competition.  Each of Seller and each of the Owners, severally and not
     ---------------
     jointly, agrees that, during the period (the "Restrictive Period") of five
     years from and after the Closing Date, he, she or it will not, without the
     prior written consent of Buyer, directly or indirectly, individually or
     jointly with others, in whole or in part, own, sponsor, organize, promote,
     operate, produce, manage, control, advise, consult with, render services
     for or otherwise be associated, affiliated or involved with any organizing,
     promoting, producing or managing any exhibition or conference, or
     marketing, selling, producing or distributing any publication or ancillary
     business-to-business marketing product or service (collectively, a
     "Competing Business") anywhere in the United States, Canada and Mexico (the
     "Restricted Territory") which (a) is marketed to, promoted to, sold to or
     otherwise involved, exclusively or non-exclusively, with the fashion and/or
     apparel industry; (b) is directed toward an exhibitor or attendee base
     substantially the same as the exhibitor or attendee base of Events
     conducted by Seller prior to the Closing; (c) is directed toward an
     advertiser or circulation base substantially the same as the advertiser or
     circulation base of the Publication published by Seller prior to the
     Closing; and/or (d) otherwise competes with any of the Future Events,
     Future Publications or Future Ancillary Products as operated by Buyer
     during the Restrictive Period consistent with Seller's operation prior to
     the Closing Date. Each of Seller and each of the Owners acknowledges and
     agrees that (a) many of the exhibitors and attendees who participate in the
     Events do or could solicit sales and/or operate throughout the Restricted
     Territory and therefore any such event held anywhere in the Restricted
     Territory would be a Competing Business and (b) that many of the
     advertisers who advertise in the Publication do or could advertise and/or
     operate throughout the Restricted Territory and that therefore any such
     publication circulated anywhere in the Restricted Territory would be a
     Competing Business. Each of Seller and each of the Owners further
     acknowledges and agrees that the duration, scope and geographical limit of
     the foregoing covenant is reasonable and necessary to protect the
     legitimate interest of the Business and Buyer. Notwithstanding the
     foregoing, at no time shall Seller or any of the Owners be prohibited from
     owning not more than one percent of the outstanding securities of any
     publicly traded entity; provided, that such ownership does not involve the
     rendering of any services or otherwise violate any aspect (other than the
     ownership aspect) of the foregoing covenant. Buyer

                                      -32-
<PAGE>

     acknowledges and agrees that the businesses as conducted by Seller on the
     date of this Agreement in connection with the Excluded Publications, AES
     Internet LLC and Easy Soft, Inc. are not Competing Businesses.

9.11 Non-Retention.  Each of Seller and each of the Owners, severally and
     -------------
     not jointly, agrees that, during the Restricted Period, he, she or it will
     not, without the prior written consent of Buyer, directly or indirectly,
     individually or jointly with others, solicit for employment, employ as an
     employee or retain as an independent contractor any of the Employees or any
     other person who is then or was at any time during the prior twelve months
     employed by Buyer in connection with the Business.

9.12 Damages and Equitable Relief.
     ----------------------------

     (a)  Each of Seller and each of the Owners, severally and not jointly,
          acknowledges and agrees that any breach of Sections 9.9, 9.10 and/or
          9.11 by such party will cause the Business and Buyer irreparable
          injury and damage.  Each of Seller and each of the Owners, therefore,
          severally and not jointly, expressly agrees that Buyer shall be
          entitled to injunctive and/or other equitable relief to prevent an
          anticipatory or continuing breach and to secure enforcement of any
          part of Sections 9.9, 9.10 and/or 9.11.  Nothing herein shall be
          construed as a waiver by Buyer of any right it may now have or
          hereafter acquire to monetary damages by reason of any injury to its
          property, business or reputation or otherwise arising out of any such
          breach or any otherwise wrongful act or omission by Seller and/or any
          of the Owners.

     (b)  While the restrictions and covenants set forth in Sections 9.9, 9.10
          and 9.11 are considered by the parties to be reasonable in all the
          circumstances, it is recognized that restrictions and covenants of the
          nature in question may fail for technical reasons unforeseen, and
          accordingly it is hereby agreed and declared that if any of such
          restrictions or covenants shall be adjudged to be void as going beyond
          what is reasonable in all the circumstances for the protection of the
          interests of Buyer but would be valid if part of the wording thereof
          were deleted or modified, the time period thereof reduced, the range
          of activities reduced in scope, the geographic area covered thereby
          reduced and/or any other modification made, the said restriction or
          covenant shall apply with such modifications as may be necessary to
          make it valid and effective. In case any one or more of the provisions
          of this Agreement should be found to be invalid, illegal or
          unenforceable in any respect, the validity, legality and enforceable
          nature of the remaining provisions contained herein shall not in any
          way be affected or impaired thereby.

ADVANSTAR TO ACQUIRE THE LARKIN GROUP AND ALIGN WITH MAGIC SHOWS
- ----------------------------------------------------------------
- --Adds international Fashion Boutique Shows, Style Industrie shows,
- -------------------------------------------------------------------
International Fashion Kids Shows, International Fashion Fabric Exhibitions, and
- -------------------------------------------------------------------------------
Accent magazine
- ---------------

CLEVELAND, OHIO -- July 12, 1999 -- Advanstar Communication, Inc. and its
subsidiary MAGIC International, producers of the world's largest fashion and
apparel trade show, today announced that Advanstar has signed a definitive
agreement to acquire the Larkin Group headquartered in Newton, Mass.  The
transaction will bring the Larkin Group's 16 trade shows serving the fashion and
fabric/textile industries and one magazine serving the accessory industry into
the Advanstar family of business and professional trade shows, publications,
conferences and marketing services serving 18 targeted industry sectors.

"This acquisition continues our strategy to add quality marketing communication
opportunities for our customers in our targeted industry sectors. The Larkin
Group's highly-regarded fashion and apparel shows complement our world-renowned
MAGIC events, strengthen our leading presence in the fashion and apparel market,
and expand our reach into other fashion-related markets including accessories,
fabrics and textiles," said Bob Krakoff, Chairman & CEO of Advanstar.

The Larkin Group trade shows held in New York City at the Jacob K. Javits Center
consist of five International Fashion Boutique Shows focusing on moderate price
point women's apparel,

                                      -2-

accessories, footwear and jewelry markets; five Style Industrie shows focusing
on the upscale, ready-to-wear designer clothing market, four Intentional Fashion
Kids Shows focusing on children's apparel, footwear and accessories; and two
International Fashion Fabric Exhibitions focusing on fabrics and textiles for
the apparel industry. The trade shows will become part of Advanstar's Fashion,
Apparel & Beauty Group directed by Joe Loggia, President of MAGIC International
and General Manager of Advanstar's Fashion, Apparel & Beauty Group.

"The International Fashion Boutique Shows and Style Industrie shows provide us
the platform, the right venue, location, and dates, to build a women's trade
show marketing solution much like MAGIC has evolved into for the men's apparel
market. New York is a key center for women's fashion, and I look forward to
using MAGIC's skills and resources in the New York events to enhance their value
to customers," said Loggia.

"It is very exciting when you realize that Advanstar now caters to retailers and
buyers in virtually all segments and price points in the fashion and apparel
industry. Collectively, the MAGIC and Larkin Group events will service more than
14,000 exhibitors showcasing their product lines to more than 278,000 attendees.
This is a powerful and unmatched reach," added Loggia.

The Larkin Group has been owned and managed by Larkin family members since it
was founded in 1945 by Harold and Alan Larkin. It operates from locations in
Massachusetts, New York and California.

"It was so important for us to find the right buyer, which we determined was
Advanstar, owner of MAGIC. We have a proud history, exceptional employees and
valuable customers, and I am confident the shows and magazine will flourish
under their experienced and creative leadership," said A.J. Larkin speaking on
behalf of the Larkin family.

     each Revolving Credit Lender shall be deemed to be utilized for all
     purposes of this Agreement in an amount equal to such Lender's Revolving
     Credit Commitment Percentage of the then undrawn face amount of such Letter
     of Credit.  Each Revolving Credit Lender (other than the Issuing Lender)
     agrees that, upon the issuance of any Letter of Credit hereunder, it shall
     automatically acquire a participation in the Issuing Lender's liability

     Credit Commitment Percentage of such liability, and each Revolving Credit
     Lender (other than the Issuing Lender) thereby shall absolutely,
     unconditionally and irrevocably assume, as primary obligor and not as
     surety, and shall be unconditionally obligated to the Issuing Lender to pay
     and discharge when due, its Revolving Credit Commitment Percentage of the
     Issuing Lender's liability under such Letter of Credit.

          (c)  Upon receipt from the beneficiary of any Letter of Credit of any
     demand for payment under such Letter of Credit, the Issuing Lender shall

     amount to be paid by the Issuing Lender as a result of such demand and the

     beneficiary in respect of such demand.  Notwithstanding the identity of the
     account party of any Letter of Credit, the Borrower hereby unconditionally
     agrees to pay and reimburse the Administrative Agent for account of the
     Issuing Lender for the amount of each demand for payment under such Letter
     of
<PAGE>

                                                                              23

     of Credit at or prior to the date on which payment is to be made by the
     Issuing Lender to the beneficiary thereunder, without presentment, demand,
     protest or other formalities of any kind.

          (d)  Forthwith upon its receipt of a notice referred to in paragraph
     (c) of this Section 2.03, the Borrower shall advise the Administrative
     Agent whether or not the Borrower intends to borrow hereunder to finance
     its obligation to reimburse the Issuing Lender for the amount of the
     related demand for payment and, if it does, submit a notice of such
     borrowing as provided in Section 4.05 hereof.

          (e)  Each Revolving Credit Lender (other than the Issuing Lender)
     shall pay to the Administrative Agent for account of the Issuing Lender at
     the Principal Office in Dollars and in immediately available funds, the
     amount of such Lender's Revolving Credit Commitment Percentage of any
     payment under a Letter of Credit upon notice by the Issuing Lender (through
     the Administrative Agent) to such Revolving Credit Lender requesting such
     payment and specifying such amount.  Each such Revolving Credit Lender's
     obligation to make such payment to the Administrative Agent for account of
     the Issuing Lender under this paragraph (e), and the Issuing Lender's right
     to receive the same, shall be absolute and unconditional and shall not be
     affected by any circumstance whatsoever, including, without limitation, the
     failure of any other Revolving Credit Lender to make its payment under this
     paragraph (e), the financial condition of the Borrower (or any other
     account party), the existence of any Default or the termination of the
     Revolving Credit Commitments.  Each such payment to the Issuing Lender
     shall be made without any offset, abatement, withholding or reduction
     whatsoever.  If any Revolving Credit Lender shall default in its obligation
     to make any such payment to the Administrative Agent for account of the
     Issuing Lender, for so long as such default shall continue the
     Administrative Agent may at the request of the Issuing Lender withhold from
     any payments received by the Administrative Agent under this Agreement or
     any Note for account of such Revolving Credit Lender the amount so in
     default and, to the extent so withheld, pay the same to the Issuing Lender
     in satisfaction of such defaulted obligation.

          (f)  Upon the making of each payment by a Revolving Credit Lender to
     the Issuing Lender pursuant to paragraph (e) above in respect of any Letter
     of Credit, such Lender shall, automatically and without any further action
     on the part of the Administrative Agent, the Issuing Lender or such Lender,
     acquire (i) a participation in an amount equal to such payment in the
     Reimbursement Obligation owing to the Issuing Lender by the Borrower
     hereunder and under the Letter of Credit Documents relating to such Letter
     of Credit and (ii) a participation in a percentage equal to such Lender's
     Revolving Credit Commitment Percentage in any interest or other amounts
     payable by the Borrower hereunder and under such Letter of Credit Documents
     in respect of such Reimbursement Obligation (other than the commissions,
     charges, costs and expenses payable to the Issuing Lender pursuant to
     paragraph (g) of this Section 2.03).  Upon receipt by the Issuing Lender
     from or for account of the Borrower of any payment in respect of any
     Reimbursement Obligation or any such interest or other amount (including by
     way of setoff or application of proceeds of any collateral security) the
     Issuing Lender shall promptly pay to the Administrative Agent for account
     of each Revolving Credit Lender entitled thereto, such Revolving Credit
     Lender's Revolving Credit Commitment Percentage of such payment, each such
     payment by the Issuing Lender to be made in the same money and funds in
     which received by the Issuing Lender.  In the event any payment received by
     the Issuing Lender and so paid to the Revolving Credit Lenders hereunder is
     rescinded or must otherwise be returned by the Issuing Lender, each
     Revolving Credit Lender shall, upon the request of the Issuing Lender
     (through the Administrative Agent), repay to the Issuing Lender (through
     the Administrative Agent) the amount of such
<PAGE>

                                                                              24

     of Credit and drawings and other transactions relating thereto.

          (h)  Promptly following the end of each calendar quarter, the Issuing
     Lender shall deliver (through the Administrative Agent) to each Revolving
     Credit Lender and the Borrower a notice describing the aggregate amount of
     all Letters of Credit outstanding at the end of such quarter.  Upon the
     request of any Revolving Credit Lender from time to time, the Issuing
     Lender shall deliver any other information reasonably requested by such
     Lender with respect to each Letter of Credit then outstanding.

          (i)  The issuance by the Issuing Lender of each Letter of Credit
     shall, in addition to the conditions precedent set forth in Section 7
     hereof, be subject to the conditions precedent that (i) such Letter of
     Credit shall be in such form, contain such terms and support such
     transactions as shall be satisfactory to the Issuing Lender consistent with
     its then current practices and procedures with respect to letters of credit
     of the same type and (ii) the Borrower shall have executed and delivered
     such applications, agreements and other instruments relating to such Letter
     of Credit as the Issuing Lender shall have reasonably requested consistent
     with its then current practices and procedures with respect to letters of
     credit of the same type, provided that in the event of any conflict between
                              --------
     any such application, agreement or other instrument and the provisions of
     this Agreement or any Security Document, the provisions of this Agreement
     and the Security Documents shall control.

          (j)  To the extent that any Lender shall fail to pay any amount
     required to be paid pursuant to paragraph (e) or (f) of this Section 2.03
     on the due date therefor, such Lender shall pay interest to the Issuing
     Lender (through the Administrative Agent) on such amount from and including
     such due date to but excluding the date such payment is made at a rate per
     annum equal to the Federal

     Funds Rate, provided that if such Lender shall fail to make such payment to
                 --------
     the Issuing Lender within three Business Days of such due date, then,
     retroactively to the due date, such Lender shall be obligated to pay
     interest on such amount at the Post-Default Rate.

          (k)  The issuance by the Issuing Lender of any modification or
     supplement to any Letter of Credit hereunder shall be subject to the same
     conditions applicable under this Section 2.03 to the issuance of new
     Letters of Credit, and no such modification or supplement shall be issued
     hereunder unless either (i) the respective Letter of Credit affected
     thereby would have complied with such conditions had it originally been
     issued hereunder in such modified or supplemented form or (ii) each
     Revolving Credit Lender shall have consented thereto.

The Borrower hereby indemnifies and holds harmless each Revolving Credit Lender
and the Administrative Agent from and against any and all claims and damages,
losses, liabilities, costs or expenses that such Lender or the Administrative
Agent may incur (or that may be claimed against such Lender or the
Administrative Agent by any Person whatsoever) by reason of or in connection
with the execution and delivery or transfer of or payment or refusal to pay by
the Issuing Lender under any Letter of Credit; provided that the Borrower shall
                                               --------
not be required to indemnify any Lender or the Administrative Agent for any
claims, damages, losses, liabilities, costs or expenses to the extent, but only
to the extent, caused by (x) the willful misconduct or gross negligence of the
Issuing Lender in determining whether a request presented under any Letter of
Credit complied with the terms of such Letter of Credit or (y) in the case of
the Issuing Lender, such Lender's failure to pay under any Letter of Credit
after the presentation to it of a request strictly complying with the terms and
conditions of such Letter of Credit unless it is prohibited from doing so by an
injunction or other order of any court.  Nothing in this Section 2.03 is
intended to limit the other obligations of the Borrower, any Lender or the
Administrative Agent under this Agreement.

          2.4  Changes of Revolving Credit Commitments.  The Borrower shall have
               ---------------------------------------
the right at any time or from time to time (i)  so long as no Revolving Credit
Loans or Letter of Credit Liabilities are outstanding, to terminate the
Revolving Credit Commitments and (ii) to reduce the aggregate unused amount of
the Revolving Credit Commitments (for which purpose use of the Revolving Credit
Commitments shall be deemed to include the aggregate amount of Letter of Credit
Liabilities); provided that (x) the Borrower shall give notice of each such
              --------
termination or reduction as provided in Section 4.05 hereof and (y) each partial
reduction shall be in an aggregate amount at least equal to $5,000,000 (or a
larger multiple of $1,000,000).  The Revolving Credit Commitments once
terminated or reduced may not be reinstated.

          2.5  Commitment Fee.  The Borrower shall pay to the Administrative
               --------------
Agent for the account of each Lender a commitment fee on the daily average
unused amount of such Lender's Revolving Credit Commitment (for which purpose
the aggregate amount of any Letter of Credit Liabilities shall be deemed to be a

pro rata (based on the Revolving Credit Commitments) use of each Lender's
- --- ----
Revolving Credit Commitment) for the period from and including the
Amendment/Restatement Effective Date to but not including the earlier of the
date such Revolving Credit Commitment is terminated and the Revolving Credit
Commitment Termination Date, at a rate per annum equal to (a)  1/2 of 1%, at any
time when the Applicable Margin in respect of Eurodollar Loans that are
Revolving Credit Loans is 1.75% or higher or (b) 3/8 of 1%, at any other time.
Accrued commitment fees shall be payable on each Quarterly Date and on the
earlier of the date the relevant Commitments are terminated and the Revolving
Credit Commitment Termination Date.

          2.6  Lending Offices.  The Loans of each Type made by each Lender
               ---------------
shall be made and maintained at such Lender's Applicable Lending Office for
Loans of such Type.

                                                                              26

          2.7  Several Obligations; Remedies Independent.  The failure of any
               -----------------------------------------
Lender to make any Loan to be made by it on the date specified therefor shall
not relieve any other Lender of its obligation to make its Loan on such date,
but neither any Lender nor the Administrative Agent shall be responsible for the
failure of any other Lender to make a Loan to be made by such other Lender, and
(except as otherwise provided in Section 4.06 hereof) no Lender shall have any
obligation to the Administrative Agent or any other Lender for the failure by
such Lender to make any Loan required to be made by such Lender.  The amounts
payable by the Borrower at any time hereunder and under any Notes to each Lender
shall be a separate and independent debt and each Lender shall be entitled to
protect and enforce its rights arising out of this Agreement and any Notes, and
it shall not be necessary for any other Lender or the Administrative Agent to
consent to, or be joined as an additional party in, any proceedings for such
purposes.

          2.8  Evidence of Loans; Notes.
               ------------------------

          (a)  The Borrower agrees that, upon the request to the Administrative
Agent by any Revolving Credit Lender made on or prior to the
Amendment/Restatement Effective Date or in connection with any assignment
pursuant to Section 12.06 hereof, in order to evidence such Lender's Revolving
Credit Loans, the Borrower will execute and deliver to such Lender a single
promissory note of the Borrower substantially in the form of Exhibit A-1 hereto,
dated the Amendment/Restatement Effective Date, payable to such Lender in a
principal amount equal to the amount of its Revolving Credit Commitment as
originally in effect and otherwise duly completed.

          (b)  The Borrower agrees that, upon the request to the Administrative
Agent by any Tranche A Lender made in connection with any assignment pursuant to
Section 12.06 hereof, in order to evidence such Lender's Tranche A Term Loans,
the Borrower will execute and deliver to such Lender a single promissory note of
the Borrower substantially in the form of Exhibit A-2 hereto, dated the
Amendment/Restatement Effective Date, payable to such Lender in a principal
amount equal to the amount of its Tranche A Term Loan and otherwise duly
completed.

          (c)  The Borrower agrees that, upon the request to the Administrative
Agent by any Tranche B Lender made  in connection with any assignment pursuant

note of the Borrower substantially in the form of Exhibit A-3 hereto, dated the
Amendment/Restatement Effective Date, payable to such Lender in a principal
amount equal to the amount of its Tranche B Term Loan and otherwise duly
completed.

          (d)  The Borrower agrees that, upon the request to the Administrative
Agent by any Tranche C Lender made on or prior to the Amendment/Restatement
Effective Date or in connection with any assignment pursuant to Section 12.06
hereof, in order to evidence such Lender's Tranche C Term Loans, the Borrower
will execute and deliver to such Lender a single promissory note of the Borrower
substantially in the form of Exhibit A-4 hereto, dated the Amendment/Restatement
Effective Date, payable to such Lender in a principal amount equal to the amount
of its Tranche C Term Loan Commitment or Tranche C Term Loan, as the case may
be, and otherwise duly completed.

          (e)  Each Lender shall maintain in accordance with its usual practice
an account or accounts evidencing indebtedness of the Borrower to such Lender
resulting from each Loan of each Class made by such Lender from time to time,
including the amounts of principal and interest payable and paid to such Lender
from time to time under this Agreement.  The Administrative Agent shall record
in the Register, with separate subaccounts therein for each Lender, (i) the
amount of each Loan of each Class made hereunder, the Type thereof, and, in the
case of Eurodollar Loans, each Interest Period applicable thereto, (ii) the
amount of any principal or interest due and payable or to become due and payable
from the Borrower to each Lender hereunder and (iii) both the amount of any
payment received by the

                                                                              27

Administrative Agent hereunder from the Borrower and each Lender's share
thereof, if any. The entries made in the Register and the accounts of each
Lender maintained pursuant to this Section 2.08(e) shall, to the extent
permitted by applicable law, be prima facie evidence of the existence and
                                ----- -----
amounts of the obligations of the Borrower therein recorded; provided, however,
                                                             --------
that the failure of any Lender or the Administrative Agent to maintain the
Register or any such account, or any error therein, shall not in any manner
affect the obligation of the Borrower to repay (with applicable interest) any
Loan of any Class made to the Borrower by such Lender in accordance with the
terms of this Agreement.

          (f)  No Lender shall be entitled to have its Notes substituted or
exchanged for any reason, or subdivided for promissory notes of lesser
denominations, except in connection with a permitted assignment of all or any
portion of such Lender's relevant Commitment, Loans and Notes pursuant to
Section 12.06 hereof and except as provided in clause (g) below (and, if
requested by any Lender, the Borrower agrees to so exchange any Note).

          (g)  Notwithstanding the foregoing, any Lender that is not a U.S.
Person and is not a "bank" within the meaning of Section 881(c)(3)(A) of the
Code and that has made a written request to the Borrower (through the
Administrative Agent) for a promissory note and any direct or indirect assignee
of such Lender (such Lender and any such assignee, a "Qualified Foreign Lender")
                                                      ------------------------
shall receive a promissory note in registered form to evidence its Loans (i.e.
containing the optional registered note language as indicated in Exhibit A-1, A-
2, A-3 or A-4 hereto, as the case may be) (herein, a "Registered Note"), dated
                                                      ---------------
the Amendment/Restatement Effective Date, payable to such Lender or registered
assigns and otherwise duly completed.  Once issued, Registered Notes (i) shall
be deemed to and shall be "Notes" and "Tranche A Term Notes," "Tranche B Term
Notes," "Tranche C Term Notes" or "Revolving Credit Notes," as the case may be,
for all purposes under this Agreement, the Security Documents and the other Loan
Documents, (ii) may not be exchanged for Revolving Credit Notes, Tranche A Term
Notes, Tranche B Term Notes or Tranche C Term Notes, notwithstanding anything to
the contrary in this Agreement, and (iii) shall at all times thereafter be
Registered Notes, including, without limitation, following any transfer or
assignment thereof.

          (h)  Each Lender that is a "Lender" under the Existing Credit
Agreement shall return to the Borrower for cancellation any notes held by it
thereunder promptly after the Amendment/Restatement Effective Date.

          2.9  Optional Prepayments and Conversions or Continuations of Loans.
               --------------------------------------------------------------
Subject to Section 4.04 hereof, the Borrower shall have the right to prepay
Loans, or to Convert Loans of one Type into Loans of another Type or Continue
Loans of one Type as Loans of the same Type, at any time or from time to time,

provided that:  (a) the Borrower shall give the Administrative Agent notice of
- --------
each such prepayment, Conversion or Continuation as provided in Section 4.05
hereof (and, upon the date specified in any such notice of prepayment, the
amount to be prepaid shall become due and payable hereunder); (b) Eurodollar
Loans may be prepaid or Converted only on the last day of an Interest Period for
such Loans; (c) prepayments of the Term Loans shall be applied ratably to the
Tranche A Term Loans, the Tranche B Term Loans and the Tranche C Term Loans and,
in the case of each such Class, to the installments of the Term Loans in direct
order of their scheduled maturities; and (d) any Conversion or Continuation of
Eurodollar Loans shall be subject to the provisions of Section 2.01(e) hereof.
Notwithstanding the foregoing, and without limiting the rights and remedies of
the Lenders under Section 10 hereof, in the event that any Event of Default
shall have occurred and be continuing, the Administrative Agent may (and at the
request of the Majority Lenders shall) suspend the right of the Borrower to
Convert any Loan into a Eurodollar Loan, or to Continue any Loan as a Eurodollar
Loan, in which event all Loans shall be Converted (on the last day(s) of the
respective Interest Periods therefor) or Continued, as the case may be, as Base
Rate Loans.

          2.10  Mandatory Prepayments.
                ---------------------

          (a)  Casualty Events.  Upon the first anniversary of the receipt by
               ---------------
the Borrower or any of its Subsidiaries of the proceeds of insurance,
condemnation award or other compensation in respect of any Casualty Event
affecting any Property of the Borrower or any of its Subsidiaries (or upon such
earlier date as the Borrower or such Subsidiary, as the case may be, shall have
determined not to repair or replace the Property affected by such Casualty
Event), the Borrower shall prepay the Term Loans in an aggregate amount equal to
100% of the Net Available Proceeds of such Casualty Event not theretofore
applied to the repair or replacement of such Property, such prepayment and
reduction to be effected in each case in the manner and to the extent specified
in paragraph (f) of this Section 2.10.  Nothing in this paragraph (a) shall be
deemed to limit any obligation of the Borrower or any of its Subsidiaries
pursuant to any of the Security Documents to remit to a collateral or similar
account (including, without limitation, the Collateral Account) maintained by
the Administrative Agent pursuant to any of the Security Documents the proceeds
of insurance, condemnation award or other compensation received in respect of
any Casualty Event.

          (b)  Debt Issuance.  Upon any Debt Issuance, the Borrower shall prepay
               -------------
the Term Loans in an amount equal to 100% of the Net Available Proceeds thereof,
with such prepayment to be made on the date of receipt of any such Net Available
Proceeds.

          (c)  Equity Issuance.  Upon any Equity Issuance, the Borrower shall
               ---------------
prepay the Term Loans in an aggregate amount equal to 50% of the Net Available
Proceeds thereof, such prepayment to be effected in each case in the manner and
to the extent specified in paragraph (f) of this Section 2.10.

          (d)  Excess Cash Flow.  Not later than the 30 days after the receipt
               ----------------
by the Administrative Agent of the annual audited consolidated and consolidating
financial statements of the Company and its Subsidiaries in accordance with
Section 9.01(b) hereof (or, if such consolidated and consolidating financial
statements are not received by the last day on which they are required to be
delivered, not later than 30 days after the last day on which such financial
statements are required by said Section 9.01(b) to be so delivered) in respect
of each fiscal year of the Company ending on or after December 31, 1999, the
Borrower shall prepay the Term Loans in an aggregate amount equal to the excess
of (A) 50% of Excess Cash Flow for such fiscal year over (B) the aggregate
amount of prepayments of Term Loans made during such fiscal year pursuant to
Section 2.09 hereof, such prepayment to be effected in each case in the manner
and to the extent specified in paragraph (f) of this Section 2.10.

          (e)  Sale of Assets.  Without limiting the obligation of the Borrower
               --------------
to obtain the consent of the Majority Lenders pursuant to Section 9.05 hereof to
any Disposition not otherwise permitted hereunder, in the event that the Net
Available Proceeds of any Disposition (herein, the "Current Disposition"), and
                                                    -------------------
of all prior Dispositions as to which a prepayment has not yet been made under
this Section 2.10(e), but excluding the amount of any Reinvestable Proceeds (as
defined below), shall exceed $1,000,000 then, no later than five Business Days
after the occurrence of the Current Disposition, the Borrower will deliver to
the Lenders a statement, certified by a Responsible Officer of the Borrower, in

Net Available Proceeds of the Current Disposition and of all such prior
Dispositions and will prepay the Term Loans in an aggregate amount equal to 100%
of the Net Available Proceeds of the Current Disposition and such prior
Dispositions, but excluding the amount of any Reinvestable Proceeds, such
prepayment to be effected in each case in the manner and to the extent specified
in paragraph (f) of this Section 2.10.  In the event that the Borrower
determines that it plans to use a portion of the Net Available Proceeds of any
Disposition (the "Reinvestable Proceeds" of such Disposition) to repair or
                  ---------------------
replace any of its Properties, it may so use such portion within 270 days of
such Disposition; provided that (i) if it fails so to use such portion, such

portion shall cease to be Reinvestable Proceeds on such 270th day and shall be
deemed to be Net Available Proceeds of a Disposition that has occurred on such
day and (ii) if after giving effect to such determination

the then aggregate amount of Reinvestable Proceeds that have not been used to so
repair or replace Properties shall be in excess of $10,000,000, such aggregate
amount shall be promptly deposited in a cash collateral account established at
Chase to be held as collateral in favor of the Administrative Agent for the
benefit of the Lenders on terms reasonably satisfactory to the Administrative
Agent and shall remain on deposit in such cash collateral account until such
aggregate amount (or, with respect to any portion thereof, such portion) shall
be used to so repair or replace Properties or as provided in clause (i) of this
Section 2.10(e).

          (f)  Application.  Prepayments described in the above paragraphs of
               -----------
this Section 2.10 (each, a "Reduction") shall be effected as follows:  (i) the

Tranche A Amount (as defined below) of such Reduction shall be applied to the
prepayment of installments of the Tranche A Term Loans then outstanding pro rata

purposes of this Section 2.10(f), with respect to any Reduction, (A) "Tranche A

Amount and the Tranche C Amount, (B) "Tranche B Amount" shall mean the product
                                      ----------------
of the amount of such Reduction multiplied by a fraction the numerator of which
is the aggregate principal amount of the Tranche B Term Loans then outstanding

denominator of which is the aggregate principal amount of the Term Loans then
outstanding; provided that, so long as and to the extent that any Tranche A Term
             --------
Loans are outstanding, if any Tranche B Lender or Tranche C Lender so advises
the Administrative Agent on or before the date of such Reduction, such Lender's

pro rata portion of the Tranche B Amount or the Tranche C Amount, as the case
- --- ----
may be, for such Reduction shall be zero.

          3.1  Repayment of Loans.
               ------------------

          (a)  The Borrower hereby promises to pay to the Administrative Agent
for account of each Lender the entire outstanding principal amount of such
Lender's Revolving Credit Loans, and each Revolving Credit Loan shall mature, on
the Revolving Credit Commitment Termination Date.  In addition, if at any time
the aggregate principal amount of the Revolving Credit Loans, together with the
aggregate amount of all Letter of Credit Liabilities, shall exceed the Revolving
Credit Commitments, the Borrower shall, first, pay Revolving Credit Loans and,
second, provide cover for Letter of Credit Liabilities, in an aggregate amount
equal to such excess.  In the event that the Borrower shall be required pursuant
to this Section 3.01(a) to provide cover for Letter of Credit Liabilities, the
Borrower shall effect the same by paying to the Administrative Agent immediately
available funds in an amount equal to the required amount, which funds shall be
retained by the Administrative Agent in the Collateral Account (as provided
therein as collateral security in the first instance for the Letter of Credit
Liabilities) until such time as the Letters of Credit shall have been terminated
and all of the Letter of Credit Liabilities paid in full.

          (b)  The Borrower hereby promises to pay to the Administrative Agent
for account of the Tranche A Lenders the aggregate principal amount of the
Tranche A Term Loans in quarterly installments payable on the Tranche A
Principal Payment Dates as follows:

          3.2  Interest.  The Borrower hereby promises to pay to the
               --------
Administrative Agent for account of each Lender interest on the unpaid principal
amount of each Loan made by such Lender for the period from and including the
date of such Loan to but excluding the date such Loan shall be paid in full, at
the following rates per annum:

          (a)  during such periods as such Loan is a Base Rate Loan, the Base
     Rate (as in effect from time to time) plus the Applicable Margin and
                                           ----

          (b)  during such periods as such Loan is a Eurodollar Loan, for each
     Interest Period relating thereto, the Eurodollar Rate for such Loan for
     such Interest Period plus the Applicable Margin.
                          ----

Notwithstanding the foregoing, the Borrower hereby promises to pay to the
Administrative Agent for account of each Lender interest at the applicable Post-
Default Rate on any principal of any Loan made by such Lender, on any
Reimbursement Obligation held by such Lender and on any other amount payable by
the Borrower hereunder or under any Notes held by such Lender to or for account
of such Lender, that shall not be paid in full when due (whether at stated
maturity, by acceleration, by mandatory prepayment or otherwise), for the period
from and including the due date thereof to but excluding the date the same is
paid in full.  Accrued interest on each Loan shall be payable (i) in the case of
a Base Rate Loan, quarterly on the Quarterly Dates, (ii) in the case of a
Eurodollar Loan, on the last day of each Interest Period therefor and, if such
Interest Period is longer than three months, at three-month intervals following
the first day of such Interest Period, and (iii) in the case of any Eurodollar
Loan, upon the payment or prepayment thereof or the Conversion of such Loan to a
Loan of another Type (but only on the principal amount so paid, prepaid or
Converted), except that interest payable at the Post-Default Rate shall be
payable from time to time on demand.  Promptly after the determination of any
interest rate provided for herein or any change therein, the Administrative
Agent shall give notice thereof to the Lenders to which such interest is payable
and to the Borrower.

due date to be deemed to have been made on the next succeeding Business Day).

          (b)  Any Lender for whose account any such payment is to be made may
(but shall not be obligated to) debit the amount of any such payment that is not
made by such time as required hereunder to any ordinary deposit account of the
Borrower with such Lender (with notice to the Borrower and the Administrative
Agent), provided that such Lender's failure to give such notice shall not affect
        --------
the validity thereof.

          (c)  The Borrower shall, at the time of making each payment under this
Agreement or any Note for account of any Lender, specify to the Administrative
Agent (which shall so notify the intended recipient(s) thereof) the Loans,
Reimbursement Obligations or other amounts payable by the Borrower hereunder to
which such payment is to be applied (and in the event that the Borrower fails to
so specify, or if such payment is equal to the then aggregate amounts due and
owing hereunder, the Administrative

for account of such Lender's Applicable Lending Office for the Loan or other
obligation in respect of which such payment is made.

          (e)  If the due date of any payment under this Agreement or any Note
would otherwise fall on a day that is not a Business Day, such date shall be
extended to the next succeeding Business Day, and interest shall be payable for
any principal so extended for the period of such extension.

Payment to the Administrative Agent, the Administrative Agent may assume that

obligated to pay interest on the Required Payment as follows:

               (i)   if the Required Payment shall represent a payment to be
     made by the Borrower to the Lenders, the Borrower and the recipient(s)
     shall each be obligated retroactively to the Advance Date to pay interest
     in respect of the Required Payment at the Post-Default Rate (without
     duplication of the obligation of the Borrower under Section 3.02 hereof to
     pay interest on the Required Payment at the Post-Default Rate), it being
     understood that the return by the recipient(s) of the Required Payment to
     the Administrative Agent shall not limit such obligation of the Borrower
     under said Section 3.02 to pay interest at the Post-Default Rate in respect
     of the Required Payment and

     each be obligated retroactively to the Advance Date to pay interest in
     respect of the Required Payment pursuant to whichever of the rates
     specified in Section 3.02 hereof is applicable to the Type of such Loan, it
     being understood that the return by the Borrower of the Required Payment to
     the Administrative Agent shall not limit any claim the Borrower may have
     against the Payor in respect of such Required Payment.

          4.7  Sharing of Payments, Etc.
               -------------------------

          (a)  Each Obligor agrees that, in addition to (and without limitation
of) any right of set-off, banker's lien or counterclaim a Lender may otherwise
have, each Lender shall be entitled, at its option (to the fullest extent
permitted by law), to set off and apply any deposit (general or special, time or
demand, provisional or final), or other indebtedness, held by it for the credit
or account of such Obligor at any of its offices, in Dollars or in any other
currency, against any principal of or interest on any of such Lender's Loans,
Reimbursement Obligations or any other amount payable to such Lender hereunder,
that is not paid when due (regardless of whether such deposit or other
indebtedness are then due to such Obligor), in which case it shall promptly
notify such Obligor and the Administrative Agent thereof, provided that such
                                                          --------
Lender's failure to give such notice shall not affect the validity thereof.

          (b)  If any Lender shall obtain from any Obligor payment of any
principal of or interest on any Loan of any Class or Letter of Credit Liability
owing to it or payment of any other amount under this Agreement or any other
Loan Document through the exercise of any right of set-off, banker's lien or
counterclaim or similar right or otherwise (other than from the Administrative
Agent as provided herein), and, as a result of such payment, such Lender shall
have received a greater percentage of the principal of or interest on the Loans
of such Class or Letter of Credit Liabilities or such other amounts then due
hereunder or thereunder by such Obligor to such Lender than the percentage
received by any other Lender, it shall promptly purchase from such other Lenders
participations in (or, if and to the extent specified by such Lender, direct
interests in) the Loans of such Class or Letter of Credit Liabilities or such
other amounts, respectively, owing to such other Lenders (or in interest due
thereon, as the case may be) in such amounts, and make such other adjustments
from time to time as shall be equitable, to the end that all the Lenders shall
share the benefit of such excess payment (net of any expenses that may be
incurred by such Lender in obtaining or preserving such excess payment) pro rata
                                                                        --- ----
in accordance with the unpaid principal of and/or interest on the Loans of such
Class or Letter of Credit Liabilities or such other amounts, respectively, owing
to each of the Lenders.  To such end all the Lenders shall make appropriate
adjustments among themselves (by the resale of participations sold or otherwise)
if such payment is rescinded or must otherwise be restored.

                                                                              36

          (c)  Each Obligor agrees that any Lender so purchasing such a
participation (or direct interest) may exercise all rights of set-off, banker's
lien, counterclaim or similar rights with respect to such participation as fully
as if such Lender were a direct holder of Loans or other amounts (as the case
may be) owing to such Lender in the amount of such participation.

          (d)  Nothing contained herein shall require any Lender to exercise any
such right or shall affect the right of any Lender to exercise, and retain the
benefits of exercising, any such right with respect to any other indebtedness or
obligation of any Obligor.  If, under any applicable bankruptcy, insolvency or
other similar law, any Lender receives a secured claim in lieu of a set-off to
which this Section 4.07 applies, such Lender shall, to the extent practicable,
exercise its rights in respect of such secured claim in a manner consistent with
the rights of the Lenders entitled under this Section 4.07 to share in the
benefits of any recovery on such secured claim.

          5.1  Additional Costs.
               ----------------

          (a)  The Borrower shall pay directly to each Lender from time to time
such amounts as such Lender may determine to be necessary to compensate such
Lender for any costs that such Lender determines are attributable to its making
or maintaining of any Eurodollar Loans or its obligation to make any Eurodollar
Loans hereunder, or any reduction in any amount receivable by such Lender
hereunder in respect of any of such Loans or such obligation (such increases in
costs and reductions in amounts receivable being herein called "Additional
                                                                ----------
Costs"), resulting from any Regulatory Change that:
- -----

               (i)   shall subject any Lender (or its Applicable Lending Office
     for any of such Loans) to any tax, duty or other charge in respect of such
     Loans or its Notes or changes the basis of taxation of any amounts payable
     to such Lender under this Agreement or its Notes in respect of any of such
     Loans (excluding changes in the rate of tax on the overall net income of
     such Lender or of such Applicable Lending Office by the jurisdiction in
     which such Lender has its principal office or such Applicable Lending
     Office); or

               (ii)  imposes or modifies any reserve, special deposit or
     similar requirements (other than the Reserve Requirement utilized in the
     determination of the Eurodollar Rate for such Loan) relating to any
     extensions of credit or other assets of, or any deposits with or other
     liabilities of, such Lender (including, without limitation, any of such
     Loans or any deposits referred to in the definition of "Eurodollar Base
     Rate" in Section 1.01 hereof), or any commitment of such Lender (including,
     without limitation, the Revolving Credit Commitment of such Lender
     hereunder); or

               (iii) imposes any other condition affecting this Agreement or its
     Notes (or any of such extensions of credit or liabilities) or its Revolving
     Credit Commitment.

If any Lender requests compensation from the Borrower under this Section
5.01(a), the Borrower may, by notice to such Lender (with a copy to the
Administrative Agent), suspend the obligation of such Lender thereafter to make
or Continue Eurodollar Loans, or to Convert Base Rate Loans into Eurodollar
Loans, until the Regulatory Change giving rise to such request ceases to be in
effect (in which case the provisions of Section 5.04 hereof shall be
applicable), provided that such suspension shall not affect the right of such
             --------
Lender to receive the compensation so requested.

          (b)  Without limiting the effect of the foregoing provisions of this
Section 5.01 (but without duplication), the Borrower shall pay directly to each
Lender from time to time on request such amounts as such Lender may determine to
be necessary to compensate such Lender (or, without

                                                                              37

any costs that it determines are attributable to the maintenance by such Lender
(or any Applicable Lending Office or such bank holding company), pursuant to any
law or regulation or any interpretation, directive or request (whether or not
having the force of law and whether or not failure to comply therewith would be
unlawful) of any court or governmental or monetary authority (i) following any
Regulatory Change or (ii) implementing any risk-based capital guideline or other
requirement (whether or not having the force of law and whether or not the
failure to comply therewith would be unlawful) hereafter issued by any
government or governmental or supervisory authority implementing at the national
level the Basle Accord, of capital in respect of its Revolving Credit Commitment
or Loans (such compensation to include, without limitation, an amount equal to
any reduction of the rate of return on assets or equity of such Lender (or any
Applicable Lending Office or such bank holding company) to a level below that
which such Lender (or any Applicable Lending Office or such bank holding
company) could have achieved but for such law, regulation, interpretation,
directive or request).

          (c)  Each Lender shall notify the Borrower of any event occurring
after the date hereof entitling such Lender to compensation under paragraph (a)
or (b) of this Section 5.01 as promptly as practicable, but in any event within
45 days, after such Lender obtains actual knowledge thereof; provided that (i)
                                                             --------
if any Lender fails to give such notice within 45 days after it obtains actual
knowledge of such an event, such Lender shall, with respect to compensation
payable pursuant to this Section 5.01 in respect of any costs resulting from
such event, only be entitled to payment under this Section 5.01 for costs
incurred from and after the date 45 days prior to the date that such Lender does
give such notice and (ii) each Lender will designate a different Applicable
Lending Office for the Loans of such Lender affected by such event if such
designation will avoid the need for, or reduce the amount of, such compensation
and will not, in the sole opinion of such Lender, be disadvantageous to such
Lender, except that such Lender shall have no obligation to designate an
Applicable Lending Office located in the United States of America.  Each Lender
will furnish to the Borrower a certificate setting forth the basis and amount of
each request by such Lender for compensation under paragraph (a) or (b) of this
Section 5.01.  Determinations and allocations by any Lender for purposes of this
Section 5.01 of the effect of any Regulatory Change pursuant to paragraph (a) of
this Section 5.01, or of the effect of capital maintained pursuant to paragraph
(b) of this Section 5.01, on its costs or rate of return of maintaining Loans or
its obligation to make Loans, or on amounts receivable by it in respect of
Loans, and of the amounts required to compensate such Lender under this Section
5.01, shall be conclusive, provided that such determinations and allocations are
                           --------
made on a reasonable basis.

          5.2  Limitation on Types of Loans.  Anything herein to the contrary
               ----------------------------
notwithstanding, if, on or prior to the determination of any Eurodollar Base
Rate for any Interest Period:

          (a)  the Administrative Agent determines, which determination shall be
     conclusive, that quotations of interest rates for the relevant deposits
     referred to in the definition of "Eurodollar Base Rate" in Section 1.01
     hereof are not being provided in the relevant amounts or for the relevant
     maturities for purposes of determining rates of interest for Eurodollar
     Loans as provided herein; or

          (b)  if the related Loans are Revolving Credit Loans, the Majority
     Revolving Credit Lenders or, if the related Loans are Term Loans, the
     Majority Term Lenders determine, which determination shall be conclusive,
     and notify the Administrative Agent that the relevant rates of interest
     referred to in the definition of "Eurodollar Base Rate" in Section 1.01
     hereof upon the basis of which the rate of interest for Eurodollar Loans
     for such Interest Period is to be determined are not likely adequately to
     cover the cost to such Lenders of making or maintaining Eurodollar Loans
     for such Interest Period;
<PAGE>

                                                                              38

then the Administrative Agent shall give the Borrower and each Lender prompt
notice thereof and, so long as such condition remains in effect, the Lenders
shall be under no obligation to make additional Eurodollar Loans, to Continue
Eurodollar Loans or to Convert Base Rate Loans into Eurodollar Loans, and the
Borrower shall, on the last day(s) of the then current Interest Period(s) for
the outstanding Eurodollar Loans, either prepay such Loans or Convert such Loans
into Base Rate Loans in accordance with Section 2.09 hereof.

          5.3  Illegality.  Notwithstanding any other provision of this
               ----------
Agreement, in the event that it becomes unlawful for any Lender or its
Applicable Lending Office to honor its obligation to make or maintain Eurodollar
Loans hereunder (and, in the sole opinion of such Lender, the designation of a
different Applicable Lending Office would either not avoid such unlawfulness or
would be disadvantageous to such Lender), then such Lender shall promptly notify
the Borrower thereof (with a copy to the Administrative Agent) and such Lender's
obligation to make or Continue, or to Convert Loans of any other Type into,
Eurodollar Loans shall be suspended until such time as such Lender may again
make and maintain Eurodollar Loans (in which case the provisions of Section 5.04
hereof shall be applicable).

          5.4  Treatment of Affected Loans.  If the obligation of any Lender to
               ---------------------------
make Eurodollar Loans or to Continue, or to Convert Base Rate Loans into,
Eurodollar Loans shall be suspended pursuant to Section 5.01 or 5.03 hereof,
such Lender's Eurodollar Loans shall be automatically Converted into Base Rate
Loans on the last day(s) of the then current Interest Period(s) for Eurodollar
Loans (or, in the case of a Conversion resulting from a circumstance described
in Section 5.03 hereof, on such earlier date as such Lender may specify to the
Borrower with a copy to the Administrative Agent) and, unless and until such
Lender gives notice as provided below that the circumstances specified in
Section 5.01 or 5.03 hereof that gave rise to such Conversion no longer exist:

          (a)  to the extent that such Lender's Eurodollar Loans have been so
     Converted, all payments and prepayments of principal that would otherwise
     be applied to such Lender's Eurodollar Loans shall be applied instead to
     its Base Rate Loans; and

          (b)  all Loans that would otherwise be made or Continued by such
     Lender as Eurodollar Loans shall be made or Continued instead as Base Rate
     Loans, and all Base Rate Loans of such Lender that would otherwise be
     Converted into Eurodollar Loans shall remain as Base Rate Loans.

If such Lender gives notice to the Borrower with a copy to the Administrative
Agent that the circumstances specified in Section 5.01 or 5.03 hereof that gave
rise to the Conversion of such Lender's Eurodollar Loans pursuant to this
Section 5.04 no longer exist (which such Lender agrees to do promptly upon such
circumstances ceasing to exist) at a time when Eurodollar Loans of the same
Class made by other Lenders are outstanding, such Lender's Base Rate Loans of
such Class shall be automatically Converted, on the first day(s) of the next
succeeding Interest Period(s) for such outstanding Eurodollar Loans, to the
extent necessary so that, after giving effect thereto, all Base Rate and
Eurodollar Loans of such Class are allocated among the Lenders ratably (as to
principal amounts, Types and Interest Periods) in accordance with their
respective Commitments of such Class.

          5.5  Compensation.  The Borrower shall pay to the Administrative Agent
               ------------
for account of each Lender, upon the request of such Lender through the
Administrative Agent, such amount or amounts as shall be sufficient (in the
reasonable opinion of such Lender) to compensate it for any loss, cost or
expense that such Lender determines is attributable to:

          (a)  any payment, mandatory or optional prepayment or Conversion of a
     Eurodollar Loan made by such Lender for any reason (including, without
     limitation, the acceleration of the Loans
<PAGE>

                                                                              39

     pursuant to Section 10 hereof) on a date other than the last day of the
     Interest Period for such Loan; or

          (b)  any failure by the Borrower for any reason (including, without
     limitation, the failure of any of the conditions precedent specified in
     Section 7 hereof to be satisfied) to borrow a Eurodollar Loan from such
     Lender on the date for such borrowing specified in the relevant notice of
     borrowing given pursuant to Section 2.02 hereof.

Without limiting the effect of the preceding sentence, such compensation shall
include an amount equal to the excess, if any, of (i) the amount of interest
that otherwise would have accrued on the principal amount so paid, prepaid,
Converted or not borrowed for the period from the date of such payment,
prepayment, Conversion or failure to borrow to the last day of the then current
Interest Period for such Loan (or, in the case of a failure to borrow, the
Interest Period for such Loan that would have commenced on the date specified
for such borrowing) at the applicable rate of interest for such Loan provided
for herein over (ii) the amount of interest that otherwise would have accrued on
such principal amount at a rate per annum equal to the interest component of the
amount such Lender would have bid in the London interbank market for Dollar
deposits of leading banks in amounts comparable to such principal amount and
with maturities comparable to such period (as reasonably determined by such
Lender).

          5.6  Additional Costs in Respect of Letters of Credit.  Without
               ------------------------------------------------
limiting the obligations of the Borrower under Section 5.01 hereof (but without
duplication), if as a result of any Regulatory Change or any risk-based capital
guideline or other requirement hereafter issued by any government or
governmental or supervisory authority implementing at the national level the
Basle Accord there shall be imposed, modified or deemed applicable any tax,
reserve, special deposit, capital adequacy or similar requirement against or
with respect to or measured by reference to Letters of Credit issued or to be
issued hereunder and the result shall be to increase the cost to any Lender or
Lenders of issuing (or purchasing participations in) or maintaining its
obligation hereunder to issue (or purchase participations in) any Letter of
Credit hereunder or reduce any amount receivable by any Lender hereunder in
respect of any Letter of Credit (which increases in cost, or reductions in
amount receivable, shall be the result of such Lender's or Lenders' reasonable
allocation of the aggregate of such increases or reductions resulting from such
event), then, not later than five Business Days following demand by such Lender
or Lenders (through the Administrative Agent), the Borrower shall pay to the
Administrative Agent for account of such Lender or Lenders, from time to time as
specified by such Lender or Lenders (through the Administrative Agent), such
additional amounts as shall be sufficient to compensate such Lender or Lenders
(through the Administrative Agent) for such increased costs or reductions in
amount.  A statement as to such increased costs or reductions in amount incurred
by any such Lender or Lenders, submitted by such Lender or Lenders to the
Borrower shall be conclusive in the absence of manifest error as to the amount
thereof.

          5.7  U.S. Taxes.
               ----------

          (a)  The Borrower agrees to pay to each Lender that is not a U.S.
Person such additional amounts as are necessary in order that the net payment of
any amount due to such non-U.S. Person hereunder after deduction for or
withholding in respect of any U.S. Taxes imposed with respect to such payment
(or in lieu thereof, payment of such U.S. Taxes by such non-U.S. Person), will
not be less than the amount stated herein to be then due and payable, provided
                                                                      --------
that the foregoing obligation to pay such additional amounts shall not apply:

               (i)   to any payment to any Lender hereunder (other than to any
     Qualified Foreign Lender) unless such Lender is, on the
     Amendment/Restatement Effective Date (or on the date it becomes a Lender
     hereunder as provided in Section 12.06(b) hereof) and on the date of any
     change in the Applicable Lending Office of such Lender, either entitled to
     submit a Form 1001

     the Loans) or Form 4224 (relating to all interest to be received by such
     Lender hereunder in respect of the Loans),

     in respect of its Loan, unless such Qualified Foreign Lender (or, if such
     Qualified Foreign Lender is not the beneficial owner of such Loan, the
     beneficial owner thereof) is, on the Amendment/Restatement Effective Date

     in Section 12.06(b) hereof) and on the date of any change in the Applicable
     Lending Office of such Lender, entitled to submit a Form W-8, together with
     an annual certificate stating that such Qualified Foreign Lender (or
     beneficial owner, as the case may be) is not a "bank" within the meaning of
     Section 881(c)(3)(A) of the Code, and such Qualified Foreign Lender (or
     beneficial owner, as the case may be) shall promptly notify the Borrower if
     at any time, such Qualified Foreign Lender (or beneficial owner, as the
     case may be) determines that it is no longer in a position to provide such
     certificate to the Borrower (or any other form of certification adopted by
     the relevant taxing authorities of the United States of America for such
     purposes), or

               (iii)  to any U.S. Taxes imposed solely by reason of the failure
     by such non-U.S. Person (or, if such non-U.S. Person is not the beneficial
     owner of the relevant Loan, such beneficial owner) to comply with
     applicable certification, information, documentation or other reporting
     requirements concerning the nationality, residence, identity or connections
     with the United States of America of such non-U.S. Person (or beneficial
     owner, as the case may be) if such compliance is required by statute or

Agent or any Lender from which it is required by law to make any deduction or
withholding, and within 30 days after it is required by law to remit such
deduction or withholding to any relevant taxing or other authority, the Borrower
shall deliver to the Administrative Agent for delivery to such non-U.S. Person
evidence satisfactory to such Person of such deduction, withholding or payment

Administrative Agent and to the Borrower on the Amendment/Restatement Effective
Date (or on the date it becomes a Lender hereunder as provided in Section
12.06(b) hereof) and annually thereafter.

          5.8  Replacement of Lenders.  If any Lender requests compensation
               ----------------------
pursuant to Section 5.01, 5.06 or 5.07 hereof, or any Lender's obligation to
make or Continue, or to Convert Loans of any Type into, the other Type of Loan
shall be suspended pursuant to Section 5.01 or 5.03 hereof (any such Lender
requesting such compensation, or whose obligations are so suspended, being
herein called a "Requesting Lender"), the Borrower, upon three Business Days
                 -----------------
notice, may require that such Requesting Lender transfer all of its right, title
and interest under this Agreement and such Requesting Lender's Notes to any bank
or other financial institution (a "Proposed Lender") identified by the Borrower
                                   ---------------
that is satisfactory to the Administrative Agent and the Issuing Lender (i) if
such Proposed Lender agrees to assume all of the obligations of such Requesting
Lender hereunder, and to purchase all of such Requesting Lender's Loans
hereunder for consideration equal to the aggregate outstanding principal amount
of such Requesting Lender's Loans, together with interest thereon to the date of
such purchase, and satisfactory arrangements are made for payment to such
Requesting Lender of all other amounts payable hereunder to such Requesting
Lender on or prior to the date of such transfer (including any fees accrued
hereunder and any amounts that would be payable under Section 5.05 hereof as if
all of such Requesting Lender's Loans were being prepaid in full on such date)
and (ii) if such Requesting Lender has requested compensation pursuant to
Section 5.01, 5.06 or 5.07 hereof, such Proposed Lender's aggregate requested
compensation, if any, pursuant to said Section 5.01, 5.06 or 5.07 with respect
to such Requesting Lender's Loans is lower than that of the Requesting Lender.
Subject to the provisions of Section 12.06(b) hereof, such Proposed Lender shall
be a "Lender" for all purposes hereunder.  Without prejudice to the survival of
any other agreement of the Borrower hereunder the agreements of the Borrower
contained in Sections 5.01, 5.06, 5.07 and 12.03 hereof (without duplication of
any payments made to such Requesting Lender by the Borrower or the Proposed
Lender) shall survive for the benefit of such Requesting Lender under this
Section 5.08 with respect to the time prior to such replacement.

          Section 6.  Guarantee.
                      ---------

          6.1  The Guarantee.  The Guarantors hereby jointly and severally
               -------------
guarantee to each Lender and the Administrative Agent and their respective
successors and assigns the prompt payment in full when due (whether at stated
maturity, by acceleration or otherwise) of the principal of and interest on the
Loans made by the Lenders to, and any Notes held by each Lender of, the Borrower
and all other amounts from time to time owing to the Lenders or the
Administrative Agent by the Borrower under this Agreement and under any Notes
and by any Obligor under any of the other Loan Documents, and all obligations of
the Borrower or any of its Subsidiaries to any Lender in respect of any Interest
Rate Protection Agreement, in each case strictly in accordance with the terms
thereof (such obligations being herein collectively called the "Guaranteed
                                                                ----------
Obligations").  The Guarantors hereby further jointly and severally agree that
- -----------
if the Borrower shall fail to pay in full when due (whether at stated maturity,
by acceleration or otherwise) any of the Guaranteed Obligations, the Guarantors
will promptly pay the same, without any demand or notice whatsoever, and that in
the case of any extension of time of payment or renewal of any of the Guaranteed
Obligations, the same will be promptly paid in full when due (whether at
extended maturity, by acceleration or otherwise) in accordance with the terms of
such extension or renewal.

          6.2  Obligations Unconditional.  The obligations of the Guarantors
               -------------------------
under Section 6.01 hereof are absolute and unconditional, joint and several,
irrespective of the value, genuineness, validity, regularity or enforceability
of the obligations of the Borrower under this Agreement, any Notes or any other
agreement or instrument referred to herein or therein, or any substitution,
release or exchange of any other guarantee of or security for any of the
Guaranteed Obligations, and, to the fullest extent permitted by applicable law,
irrespective of any other circumstance whatsoever that might otherwise
constitute a legal or equitable discharge or defense of a surety or guarantor,
it being the intent of this Section 6.02 that the
<PAGE>

                                                                              42

obligations of the Guarantors hereunder shall be absolute and unconditional,
joint and several, under any and all circumstances. Without limiting the
generality of the foregoing, it is agreed that the occurrence of any one or more
of the following shall not alter or impair the liability of the Guarantors
hereunder which shall remain absolute and unconditional as described above:

               (i)    at any time or from time to time, without notice to the
     Guarantors, the time for any performance of or compliance with any of the
     Guaranteed Obligations shall be extended, or such performance or compliance
     shall be waived;

               (ii)   any of the acts mentioned in any of the provisions of this
     Agreement or any Notes or any other agreement or instrument referred to
     herein or therein shall be done or omitted;

               (iii)  the maturity of any of the Guaranteed Obligations shall
     be accelerated, or any of the Guaranteed Obligations shall be modified,
     supplemented or amended in any respect, or any right under this Agreement
     or any Notes or any other agreement or instrument referred to herein or
     therein shall be waived or any other guarantee of any of the Guaranteed
     Obligations or any security therefor shall be released or exchanged in
     whole or in part or otherwise dealt with; or

               (iv)   any lien or security interest granted to, or in favor of,
     the Administrative Agent or any Lender or Lenders as security for any of
     the Guaranteed Obligations shall fail to be perfected.

The Guarantors hereby expressly waive diligence, presentment, demand of payment,
protest and all notices whatsoever, and any requirement that the Administrative
Agent or any Lender exhaust any right, power or remedy or proceed against the
Borrower under this Agreement or any Notes or any other agreement or instrument
referred to herein or therein, or against any other Person under any other
guarantee of, or security for, any of the Guaranteed Obligations.  Anything
herein to the contrary notwithstanding, the maximum liability of each Subsidiary
Guarantor hereunder shall in no event exceed the amount which can be guaranteed
by such Subsidiary Guarantor under applicable federal and state laws relating to
the insolvency of debtors (after giving effect to the right of contribution
established in Section 6.08 hereof).

          6.3  Reinstatement.  The obligations of the Guarantors under this
               -------------
Section 6 shall be automatically reinstated if and to the extent that for any
reason any payment by or on behalf of the Borrower in respect of the Guaranteed
Obligations is rescinded or must be otherwise restored by any holder of any of
the Guaranteed Obligations, whether as a result of any proceedings in bankruptcy
or reorganization or otherwise and the Guarantors jointly and severally agree
that they will indemnify the Administrative Agent and each Lender on demand for
all reasonable costs and expenses (including, without limitation, fees of
counsel) incurred by the Administrative Agent or such Lender in connection with
such rescission or restoration, including any such costs and expenses incurred
in defending against any claim alleging that such payment constituted a
preference, fraudulent transfer or similar payment under any bankruptcy,
insolvency or similar law.

          6.4  Subrogation.  The Guarantors hereby jointly and severally agree
               -----------
that until the payment and satisfaction in full of all Guaranteed Obligations
and the expiration and termination of the Revolving Credit Commitments under
this Agreement they shall not exercise any right or remedy arising by reason of
any performance by them of their guarantee in Section 6.01 hereof, whether by
subrogation or otherwise, against the Borrower or any other guarantor of any of
the Guaranteed Obligations or any security for any of the Guaranteed
Obligations.

          6.5  Remedies.  The Guarantors jointly and severally agree that, as
               --------
between the Guarantors and the Lenders, the obligations of the Borrower under
this Agreement and any Notes may be declared to
<PAGE>

                                                                              43

be forthwith due and payable as provided in Section 10 hereof (and shall be
deemed to have become automatically due and payable in the circumstances
provided in said Section 10) for purposes of Section 6.01 hereof notwithstanding
any stay, injunction or other prohibition preventing such declaration (or such
obligations from becoming automatically due and payable) as against the Borrower
and that, in the event of such declaration (or such obligations being deemed to
have become automatically due and payable), such obligations (whether or not due
and payable by the Borrower) shall forthwith become due and payable by the
Guarantors for purposes of said Section 6.01.

          6.6  Instrument for the Payment of Money.  Each Guarantor hereby
               -----------------------------------
acknowledges that the guarantee in this Section 6 constitutes an instrument for
the payment of money, and consents and agrees that any Lender or the
Administrative Agent, at its sole option, in the event of a dispute by such
Guarantor in the payment of any moneys due hereunder, shall have the right to
bring motion-action under New York CPLR Section 3213.

          6.7  Continuing Guarantee.  The guarantee in this Section 6 is a
               --------------------
continuing guarantee, and shall apply to all Guaranteed Obligations whenever
arising.

          6.8  Rights of Contribution.  Each Subsidiary Guarantor hereby agrees
               ----------------------
that to the extent that a Subsidiary Guarantor shall have paid more than its
proportionate share of any payment made hereunder, such Subsidiary Guarantor
shall be entitled to seek and receive contribution from and against any other
Subsidiary Guarantor hereunder which has not paid its proportionate share of
such payment.  Each Subsidiary Guarantor's right of contribution shall be
subject to the terms and conditions of Section 6.04 hereof.  The provisions of
this Section 6.08 shall in no respect limit the obligations and liabilities of
any Subsidiary Guarantor to the Administrative Agent and the Lenders, and each
Subsidiary Guarantor shall remain liable to the Administrative Agent and the
Lenders for the full amount guaranteed by such Subsidiary Guarantor hereunder.

          6.9  General Limitation on Guarantee Obligations.  In any action or
               -------------------------------------------
proceeding involving any state corporate law, or any state or Federal
bankruptcy, insolvency, reorganization or other law affecting the rights of
creditors generally, if the obligations of any Subsidiary Guarantor under
Section 6.01 hereof would otherwise, taking into account the provisions of
Section 6.08 hereof, be held or determined to be void, invalid or unenforceable,
or subordinated to the claims of any other creditors, on account of the amount
of its liability under said Section 6.01, then, notwithstanding any other
provision hereof to the contrary, the amount of such liability shall, without
any further action by such Subsidiary Guarantor, any Lender, the Administrative
Agent or any other Person, be automatically limited and reduced to the highest
amount that is valid and enforceable and not subordinated to the claims of other
creditors as determined in such action or proceeding.

          6.10  Waiver.  Each Guarantor waives all rights and defenses arising
                ------
out of an election of remedies by any Lender or the Administrative Agent, even
though that election of remedies, such as a nonjudicial foreclosure with respect
to security for a Guaranteed Obligation, has destroyed such Guarantor's right of
subrogation and reimbursement against the Borrower by the operation of Section
580d of the California Code of Civil Procedure or otherwise.  The provisions of
this Section 6.10 shall apply to each of the Loan Documents as if fully set
forth therein.

Default or Event of Default.

          (b)  Acquisition Documents.  The Administrative Agent shall have

limitation, a copy of any debt, any instrument, security agreement or other

     performance of any of its obligations under any of Sections 9.01(f),

     Administrative Agent); or

          (e)  Any Relevant Party shall admit in writing its inability to, or be
     generally unable to, pay its debts as such debts become due; or

          (f)  Any Relevant Party shall (i) apply for or consent to the

     Bankruptcy Code or (vi) take any corporate or partnership action for the
     purpose of effecting any of the foregoing; or

          (g)  A proceeding or case shall be commenced, without the application
     or consent of the affected Relevant Party, in any court of competent
     jurisdiction, seeking (i) its reorganization, liquidation, dissolution,
     arrangement or winding-up, or the composition or readjustment of its debts,
     (ii) the appointment of a receiver, custodian, trustee, examiner,
     liquidator or the like of such Relevant Party or of all or any substantial

     Bankruptcy Code; or

          (h)  A final judgment or judgments for the payment of money of
     $5,000,000 or more in the aggregate (exclusive of judgment amounts fully
     covered by insurance where the insurer has admitted liability in respect of
     such judgment), shall be rendered by one or more courts, administrative
     tribunals or other bodies having jurisdiction against any Relevant Party
     and the same shall not be discharged (or provision shall not be made for
     such discharge), or a stay of execution thereof shall not be procured,
     within 30 days from the date of entry thereof and such Relevant Party shall
     not, within said period of 30 days, or such longer period during which
     execution of the same shall have been stayed, appeal therefrom and cause
     the execution thereof to be stayed during such appeal; or

          (i)  An event or condition specified in Section 9.01(e) hereof shall
     occur or exist with respect to any Plan or Multiemployer Plan and, as a
     result of such event or condition, together with all other such events or
     conditions, the Company or any ERISA Affiliate shall incur or in the
     opinion of the Majority Lenders shall be reasonably likely to incur a
     liability to a Plan, a Multiemployer Plan or the PBGC (or any combination
     of the foregoing) that, in the determination
<PAGE>

                                                                              68

     of the Majority Lenders, would (either individually or in the aggregate)
     have a Material Adverse Effect; or

          (j)  A reasonable basis shall exist for the assertion against the
     Company or any of its Subsidiaries, or any predecessor in interest of the
     Company or any of its Subsidiaries or Affiliates, of (or there shall have
     been asserted against the Company or any of its Subsidiaries) an
     Environmental Claim that, in the judgment of the Majority Lenders is
     reasonably likely to be determined adversely to the Company or any of its
     Subsidiaries, and the amount thereof (either individually or in the
     aggregate) is reasonably likely to have a Material Adverse Effect (insofar
     as such amount is payable by the Company or any of its Subsidiaries but
     after deducting any portion thereof that is reasonably expected to be paid
     by other creditworthy Persons jointly and severally liable therefor); or

          (k)  (i) prior to the initial registered public offering of the

     or control, directly or indirectly, more than 51% of the capital stock of
     the Company, (y) the Company shall cease to own or control directly or
     indirectly all of the capital stock of the Borrower or (z) a Specified
     Change of Control shall occur, or (ii) on and after the date of the initial
     registered public offering of the Company's common stock, (w) the H&F
     Affiliated Parties shall cease to own or control, directly or indirectly,
     more than 35% of the capital stock of the Company, (x) any Person or
     "group" (as such terms are used in Sections 13(d) and 14(d) of the
     Securities Exchange Act of 1934, as amended (the "Exchange Act")), other
                                                       ------------
     than the H&F Affiliated Parties, shall become, or obtain rights (whether by
     means of warrants, options or otherwise) to become, the "beneficial owner"
     (as defined in Rules 13(d)-3 and 13(d)-5 under the Exchange Act), directly
     or indirectly, of a percentage of the outstanding shares of common stock of
     the Company which is greater than the percentage of the outstanding shares
     of common stock of the Company beneficially owned by the H&F Affiliated
     Parties, (y) the Company shall cease to own or control directly or
     indirectly all of the capital stock of the Borrower or (z) a Specified
     Change of Control shall occur; or

          (l)  (i) The Liens created by the Security Documents on the capital
     stock of the Borrower and its Subsidiaries shall at any time not constitute
     a valid and perfected Lien in favor of the Administrative Agent, free and
     clear of all other Liens, or, (ii) except for expiration in accordance with
     its terms, any of the Security Documents shall for whatever reason be
     terminated or cease to be in full force and effect, or the enforceability
     thereof shall be contested by any Obligor, or (iii) Section 6 shall cease,
     for any reason, to be in full force and effect or any Guarantor shall so
     assert; or

THEREUPON:  (1) in the case of an Event of Default other than one referred to in
clause (f) or (g) of this Section 10 with respect to any Obligor, the
Administrative Agent may (and upon the request of the Majority Lenders shall),
by notice to the Borrower, terminate the Revolving Credit Commitments and/or
declare the principal amount then outstanding of, and the accrued interest on,
the Loans, the Reimbursement Obligations and all other amounts payable by the
Obligors hereunder and under any Notes (including, without limitation, any
amounts payable under Section 5.05 or 5.06 hereof) to be forthwith due and
payable, whereupon such amounts shall be immediately due and payable without
presentment, demand, protest or other formalities of any kind, all of which are
hereby expressly waived by each Obligor; and (2) in the case of the occurrence
of an Event of Default referred to in clause (f) or (g) of this Section 10 with
respect to any Obligor, the Revolving Credit Commitments shall automatically be
terminated and the principal amount then outstanding of, and the accrued
interest on, the Loans, the Reimbursement Obligations and all other amounts
payable by the Obligors hereunder and under any Notes (including, without
limitation, any amounts payable under Section 5.05 or 5.06 hereof) shall
automatically become
<PAGE>

                                                                              69

immediately due and payable without presentment, demand, protest or other
formalities of any kind, all of which are hereby expressly waived by each
Obligor.

          In addition, upon the occurrence and during the continuance of any
Event of Default (if the Administrative Agent has declared the principal amount
then outstanding of, and accrued interest on, the Revolving Credit Loans and all
other amounts payable by the Borrower hereunder and under any Notes to be due
and payable), the Borrower agrees that it shall, if requested by the
Administrative Agent or the Majority Revolving Credit Lenders through the
Administrative Agent (and, in the case of any Event of Default referred to in
clause (f) or (g) of this Section 10 with respect to the Borrower or the
Company, forthwith, without any demand or the taking of any other action by the
Administrative Agent or such Lenders) provide cover for the Letter of Credit
Liabilities by paying to the Administrative Agent immediately available funds in
an amount equal to the then aggregate undrawn face amount of all Letters of
Credit, which funds shall be held by the Administrative Agent in the Collateral
Account as collateral security in the first instance for the Letter of Credit
Liabilities and be subject to withdrawal only as therein provided.


          Section 11.  The Administrative Agent.
                       ------------------------

          11.1  Appointment, Powers and Immunities.  Each Lender hereby appoints
                ----------------------------------
and authorizes the Administrative Agent to act as its agent hereunder and under
the other Loan Documents with such powers as are specifically delegated to the
Administrative Agent by the terms of this Agreement and of the other Loan
Documents, together with such other powers as are reasonably incidental thereto.
The Administrative Agent (which term as used in this sentence and in Section
11.05 and the first sentence of Section 11.06 hereof shall include reference to
its affiliates and its own and its affiliates' officers, directors, employees
and agents):

          (a)  shall have no duties or responsibilities except those expressly
     set forth in this Agreement and in the other Loan Documents, and shall not
     by reason of this Agreement or any other Loan Document be a trustee for any
     Lender;

          (b)  shall not be responsible to the Lenders for any recitals,
     statements, representations or warranties contained in this Agreement or in
     any other Loan Document, or in any certificate or other document referred
     to or provided for in, or received by any of them under, this Agreement or
     any other Loan Document, or for the value, validity, effectiveness,
     genuineness, enforceability or sufficiency of this Agreement, any Note or
     any other Loan Document or any other document referred to or provided for
     herein or therein or for any failure by the Borrower or any other Person to
     perform any of its obligations hereunder or thereunder;

          (c)  shall not, except to the extent expressly instructed by the
     Majority Lenders with respect to collateral security under the Security
     Documents, be required to initiate or conduct any litigation or collection
     proceedings hereunder or under any other Loan Document; and

          (d)  shall not be responsible for any action taken or omitted to be
     taken by it hereunder or under any other Loan Document or under any other
     document or instrument referred to or provided for herein or therein or in
     connection herewith or therewith, except for its own gross negligence or
     willful misconduct.

The Administrative Agent may employ agents and attorneys-in-fact and shall not
be responsible for the negligence or misconduct of any such agents or attorneys-
in-fact selected by it in good faith.  The Administrative Agent may deem and
treat the payee (or Registered Holder, as the case may be) of a Note
<PAGE>

                                                                              70

as the holder thereof for all purposes hereof unless and until a notice of the
assignment or transfer thereof shall have been filed with the Administrative
Agent.

          11.2  Reliance by Administrative Agent.  The Administrative Agent
                --------------------------------
shall be entitled to rely upon any certification, notice or other communication
(including, without limitation, any thereof by telephone, telecopy, telegram or
cable) reasonably believed by it to be genuine and correct and to have been
signed or sent by or on behalf of the proper Person or Persons, and upon advice
and statements of legal counsel, independent accountants and other experts
selected by the Administrative Agent.  As to any matters not expressly provided
for by this Agreement or any other Loan Document, the Administrative Agent shall
in all cases be fully protected in acting, or in refraining from acting,
hereunder or thereunder in accordance with instructions given by the Majority
Lenders or, if provided herein, in accordance with the instructions given by the
Majority Revolving Credit Lenders, the Majority Term Lenders or all of the
Lenders as is required in such circumstance, and such instructions of such
Lenders and any action taken or failure to act pursuant thereto shall be binding
on all of the Lenders.

          11.3  Defaults.  The Administrative Agent shall not be deemed to have
                --------
knowledge or notice of the occurrence of a Default unless the Administrative
Agent has received notice from a Lender or the Borrower specifying such Default
and stating that such notice is a "Notice of Default".  In the event that the
Administrative Agent receives such a notice of the occurrence of a Default, the
Administrative Agent shall give prompt notice thereof to the Lenders.  The
Administrative Agent shall (subject to Section 11.07 hereof) take such action
with respect to such Default as shall be directed by the Majority Lenders or, if
provided herein, the Majority Revolving Credit Lenders or the Majority Term
Lenders, provided that, unless and until the Administrative Agent shall have
         --------
received such directions, the Administrative Agent may (but shall not be
obligated to) take such action, or refrain from taking such action, with respect
to such Default as it shall deem advisable in the best interest of the Lenders
except to the extent that this Agreement expressly requires that such action be
taken, or not be taken, only with the consent or upon the authorization of the
Majority Lenders, the Majority Revolving Credit Lenders, the Majority Term
Lenders or all of the Lenders.

          11.4  Rights as a Lender.  With respect to its Revolving Credit
                ------------------
Commitment and the Loans made by it, Chase (and any successor acting as
Administrative Agent) in its capacity as a Lender hereunder shall have the same
rights and powers hereunder as any other Lender and may exercise the same as
though it were not acting as the Administrative Agent, and the term "Lender" or
"Lenders" shall, unless the context otherwise indicates, include the
Administrative Agent in its individual capacity.  Chase (and any successor
acting as Administrative Agent) and its affiliates may (without having to
account therefor to any Lender) accept deposits from, lend money to, make
investments in and generally engage in any kind of banking, trust or other
business with the Obligors (and any of their Subsidiaries or Affiliates) as if
it were not acting as the Administrative Agent, and Chase (and any such
successor) and its affiliates may accept fees and other consideration from the
Obligors for services in connection with this Agreement or otherwise without
having to account for the same to the Lenders.

          11.5  Indemnification.  The Lenders agree to indemnify the
                ---------------
Administrative Agent (to the extent not reimbursed under Section 12.03 hereof,
but without limiting the obligations of the Borrower under said Section 12.03)
ratably in accordance with the aggregate principal amount of the Loans and
Reimbursement Obligations held by the Lenders (or, if no Loans or Reimbursement
Obligations are at the time outstanding, ratably in accordance with their
respective Commitments), for any and all liabilities, obligations, losses,
damages, penalties, actions, judgments, suits, costs, expenses or disbursements
of any kind and nature whatsoever that may be imposed on, incurred by or
asserted against the Administrative Agent (including by any Lender) arising out
of or by reason of any investigation in or in any way relating to or arising out
of this Agreement or any other Loan Document or any other documents contemplated
by or referred to herein or therein or the transactions contemplated hereby or
thereby (including, without
<PAGE>

                                                                              71

limitation, the costs and expenses that the Borrower is obligated to pay under
Section 12.03 hereof, but excluding, unless a Default has occurred and is
continuing, normal administrative costs and expenses incident to the performance
of its agency duties hereunder) or the enforcement of any of the terms hereof or
thereof or of any such other documents, provided that no Lender shall be liable
                                        --------
for any of the foregoing to the extent they arise from the gross negligence or
willful misconduct of the party to be indemnified.

          11.6  Non-Reliance on Administrative Agent and Other Lenders-.  Each
                -------------------------------------------------------
Lender agrees that it has, independently and without reliance on the
Administrative Agent or any other Lender, and based on such documents and
information as it has deemed appropriate, made its own credit analysis of the
Company and its Subsidiaries and decision to enter into this Agreement and that
it will, independently and without reliance upon the Administrative Agent or any
other Lender, and based on such documents and information as it shall deem
appropriate at the time, continue to make its own analysis and decisions in
taking or not taking action under this Agreement or under any other Loan
Document.  The Administrative Agent shall not be required to keep itself
informed as to the performance or observance by any Obligor of this Agreement or
any of the other Loan Documents or any other document referred to or provided
for herein or therein or to inspect the Properties or books of the Company or
any of its Subsidiaries.  Except for notices, reports and other documents and
information expressly required to be furnished to the Lenders by the
Administrative Agent hereunder or under the Security Documents, the
Administrative Agent shall not have any duty or responsibility to provide any
Lender with any credit or other information concerning the affairs, financial
condition or business of the Company or any of its Subsidiaries (or any of their
affiliates) that may come into the possession of the Administrative Agent or any
of its affiliates.

          11.7  Failure to Act.  Except for action expressly required of the
                --------------
Administrative Agent hereunder and under the other Loan Documents, the
Administrative Agent shall in all cases be fully justified in failing or
refusing to act hereunder and thereunder unless it shall receive further
assurances to its satisfaction from the Lenders of their indemnification
obligations under Section 11.05 hereof against any and all liability and expense
that may be incurred by it by reason of taking or continuing to take any such
action.

          11.8  Resignation or Removal of Administrative Agent.  Subject to the
                ----------------------------------------------
appointment and acceptance of a successor Administrative Agent as provided
below, the Administrative Agent may resign at any time by giving notice thereof
to the Lenders and the Borrower and the Company, and the Administrative Agent
may be removed at any time with or without cause by the Majority Lenders.  Upon
any such resignation or removal, the Majority Lenders shall have the right to
appoint a successor Administrative Agent.  If no successor Administrative Agent
shall have been so appointed by the Majority Lenders and shall have accepted
such appointment within 30 days after the retiring Administrative Agent's giving
of notice of resignation or the Majority Lenders' removal of the retiring
Administrative Agent, then the retiring Administrative Agent may, on behalf of
the Lenders, appoint a successor Administrative Agent, that shall be a bank that
has an office in New York, New York with a combined capital and surplus of at
least $500,000,000.  Upon the acceptance of any appointment as Administrative
Agent hereunder by a successor Administrative Agent, such successor
Administrative Agent shall thereupon succeed to and become vested with all the
rights, powers, privileges and duties of the retiring Administrative Agent, and
the retiring Administrative Agent shall be discharged from its duties and
obligations hereunder.  After any retiring Administrative Agent's resignation or
removal hereunder as Administrative Agent, the provisions of this Section 11
shall continue in effect for its benefit in respect of any actions taken or
omitted to be taken by it while it was acting as the Administrative Agent.

          11.9  Consents under Other Loan Documents.  Except as otherwise
                -----------------------------------
provided in Section 12.04 hereof with respect to this Agreement, the
Administrative Agent may, with the prior consent of the Majority Lenders (but
not otherwise), consent to any modification, supplement or waiver under any of
the Loan Documents, provided that, without the prior consent of each Lender, the
                    --------
Administrative Agent shall
<PAGE>

                                                                              72

not (except as provided herein, in the Security Documents or in the Assumption
Agreements) release any collateral or otherwise terminate any Lien under any
Security Document providing for collateral security, agree to additional
obligations being secured by such collateral security (unless the Lien for such
additional obligations shall be junior to the Lien in favor of the other
obligations secured by such Security Document, in which event the Administrative
Agent may consent to such junior Lien provided that it obtains the consent of
the Majority Lenders thereto), alter the relative priorities of the obligations
entitled to the benefits of the Liens created under the Security Documents,
except that no such consent shall be required, and the Administrative Agent is
hereby authorized, to release any Lien covering Property that is the subject of
either a disposition of Property permitted hereunder or a disposition to which
the Majority Lenders have consented.


          Section 12.  Miscellaneous.
                       -------------

          12.1  Waiver.  No failure on the part of the Administrative Agent or
                ------
any Lender to exercise and no delay in exercising, and no course of dealing with
respect to, any right, power or privilege under this Agreement or any Note shall
operate as a waiver thereof, nor shall any single or partial exercise of any
right, power or privilege under this Agreement or any Note preclude any other or
further exercise thereof or the exercise of any other right, power or privilege.
The remedies provided herein are cumulative and not exclusive of any remedies
provided by law.

          Each Obligor irrevocably waives, to the fullest extent permitted by
applicable law, any claim that any action or proceeding commenced by the
Administrative Agent or any Lender relating in any way to this Agreement should
be dismissed or stayed by reason, or pending the resolution, of any action or
proceeding commenced by any Obligor relating in any way to this Agreement
whether or not commenced earlier.  To the fullest extent permitted by applicable
law, the Obligors shall take all measures necessary for any such action or
proceeding commenced by the Administrative Agent or any Lender to proceed to
judgment prior to the entry of judgment in any such action or proceeding
commenced by any Obligor.

          12.2  Notices.  All notices, requests and other communications
                -------
provided for herein and under the Security Documents (including, without
limitation, any modifications of, or waivers, requests or consents under, this
Agreement) shall be given or made in writing (including, without limitation, by
telecopy) delivered to the intended recipient addressed as follows in the case
of the Obligors and the Administrative Agent and as set forth in an
administrative questionnaire delivered to the Administrative Agent in the case

other Loan Documents, and any Default or Event of Default waived shall be deemed
to be cured and not continuing; no such waiver shall extend to any subsequent or
other Default or Event of Default or impair any right consequent thereon.

          Anything in this Agreement to the contrary notwithstanding, no waiver
or modification of any provision of this Agreement that has the effect (either
immediately or at some later time) of enabling the Borrower to satisfy a
condition precedent to the making of a Revolving Credit Loan shall be effective
against the Revolving Credit Lenders for the purposes of the Revolving Credit
Commitments unless the Majority Revolving Credit Lenders shall have concurred
with such waiver or modification.

          12.5  Successors and Assigns.  This Agreement shall be binding upon
                ----------------------
and inure to the benefit of the parties hereto and their respective successors
and permitted assigns.

          12.6  Assignments and Participations.
                ------------------------------

          (a)  No Obligor may assign any of its rights or obligations hereunder
or under any Notes without the prior consent of all of the Lenders and the
Administrative Agent.

          (b)  Any Lender may, in the ordinary course of its business and in
accordance with applicable law, at any time and from time to time assign to any
Lender, any Affiliate thereof, an Approved Fund of any Lender or, with the prior
written consent of the Borrower and the Administrative Agent (which in each case
shall not be unreasonably withheld), to an additional bank or financial
institution or investment funds which invest in credit facilities (an
"Assignee") all or any part of its rights and obligations under this Agreement
 --------
and any Notes, including, without limitation, its Revolving Credit Commitment,
Loans, and, if such Lender is a Revolving Credit Lender, its Letter of Credit
Interest (pursuant to an Assignment and Acceptance, substantially in the form of
Exhibit E, executed by such Assignee, such assigning Lender (and, in the case of
an Assignee that is not then a Lender or an Affiliate thereof, by the Borrower
and the Administrative Agent) and delivered to the Administrative Agent for its
acceptance and recording in the Register;  provided that (unless the Borrower
                                           --------
and the Administrative Agent otherwise consent in writing)

               (i)   except to the extent the Borrower and the Administrative
     Agent shall otherwise consent, any such partial assignment (other than to
     another Lender) shall be in an amount at least equal to $5,000,000; and

               (ii)  each such assignment by a Lender of its Revolving Credit
     Loans, Revolving Credit Note, Revolving Credit Commitment or Letter of
     Credit Interest shall be made in such manner so that the same portion of
     its Revolving Credit Loans, Revolving Credit Note, Revolving Credit
     Commitment and Letter of Credit Interest is assigned to the respective
     assignee.

Upon such execution, delivery, acceptance and recording, from and after the
effective date determined pursuant to such Assignment and Acceptance, (x) the
Assignee thereunder shall be a party hereto and, to the extent provided in such
Assignment and Acceptance, have the rights and obligations of a Lender hereunder
with a Revolving Credit Commitment and, if applicable, Letter of Credit Interest
(or a portion thereof) and the Term Loans, as set forth therein, and (y) the
assigning Lender thereunder shall be released from its obligations under this
Agreement to the extent that such obligations shall have been expressly assumed
by the Assignee pursuant to such Assignment and Acceptance (and, in the case of
an Assignment and Acceptance covering all or the remaining portion of an
assigning Lender's rights and obligations under this Agreement, such assigning
Lender shall cease to be a party hereto but shall nevertheless continue to be
entitled to the benefits of Sections 5.01, 5.05, 5.06, 5.07 and 12.03).
Notwithstanding the foregoing, no Assignee, which as of the date of any
assignment to it pursuant to this Section 12.06(b) would be entitled
<PAGE>

                                                                              77

to receive any greater payment under Section 5.01 or 5.07 than the assigning
Lender would have been entitled to receive as of such date under such Sections
with respect to the rights assigned, shall be entitled to receive such payments
unless the Borrower has expressly consented in writing to waive the benefit of
this provision at the time of the assignment.

          (c)  A Lender may sell or agree to sell to one or more other Persons
(each a "Participant") a participation in all or any part of any Loans or Letter
         -----------
of Credit Interest held by it, or in its Revolving Credit Commitment, provided
                                                                      --------
that such Participant shall not have any rights or obligations under this
Agreement or any Note or any other Loan Document (the Participant's rights
against such Lender in respect of such participation to be those set forth in
the agreements executed by such Lender in favor of the Participant).  All
amounts payable by the Borrower to any Lender under Section 5 hereof in respect
of Loans, Letter of Credit Interest held by it, and its Revolving Credit
Commitment, shall be determined as if such Lender had not sold or agreed to sell
any participations in such Loans, Letter of Credit Interest and Commitments, and
as if such Lender were funding each of such Loan, Letter of Credit Interest and
Commitments in the same way that it is funding the portion of such Loan, Letter
of Credit Interest and Commitments in which no participations have been sold.
In no event shall a Lender that sells a participation agree with the Participant
to take or refrain from taking any action hereunder or under any other Loan
Document except that such Lender may agree with the Participant that it will
not, without the consent of the Participant, agree to (i) increase or extend the
term of such Lender's related Commitment or extend the amount or date of any
scheduled reduction of such Commitment pursuant to Section 2.04 hereof, (ii)
extend the date fixed for the payment of principal of or interest on the related
Loan or Loans, Reimbursement Obligations or any portion of any fee hereunder
payable to the Participant, (iii) reduce the amount of any such payment of
principal, (iv) reduce the rate at which interest is payable thereon, or any fee
hereunder payable to the Participant, to a level below the rate at which the
Participant is entitled to receive such interest or fee or (v) consent to any
modification, supplement or waiver hereof or of any of the other Loan Documents
to the extent that the same, under Section 11.09 or 12.04 hereof, requires the
consent of each Lender.

          (d)  In addition to the assignments and participations permitted under
the foregoing provisions of this Section 12.06, any Lender may (without notice
to the Borrower, the Administrative Agent or any other Lender and without
payment of any fee) (i) assign and pledge all or any portion of its Loans and
its Notes to any Federal Reserve Bank as collateral security pursuant to
Regulation A and any Operating Circular issued by such Federal Reserve Bank and
(ii) assign all or any portion of its rights under this Agreement and its Loans
and its Notes to an affiliate.  No such assignment shall release the assigning
Lender from its obligations hereunder.

          (e)  A Lender may furnish any information concerning the Borrower or
any of its Subsidiaries in the possession of such Lender from time to time to
assignees and participants (including prospective assignees and participants),
subject, however, to the provisions of Section 12.12(b) hereof.

          (f)  Anything in this Section 12.06 to the contrary notwithstanding,
no Lender may assign or participate any interest in any Loan or Reimbursement
Obligation held by it hereunder to the Borrower or any of its Affiliates or
Subsidiaries without the prior consent of each Lender.

          (g)  The Administrative Agent, on behalf of the Borrower, shall
maintain at its Principal Office a copy of each Assignment and Acceptance
delivered to it and a register (the "Register") for the recordation of the names
                                     --------
and addresses of the Lenders and the Revolving Credit Commitments of, and the
principal amount of the Loans owing to, and any Notes evidencing such Loans
owned by, each Lender from time to time.  Notwithstanding anything in this
Agreement to the contrary, the Borrower, the Administrative Agent and the
Lenders shall treat each Person whose name is recorded in the Register as the
owner of any Loan, any Notes and the Revolving Credit Commitments recorded
therein for all purposes of this Agreement.  The Register shall be available for
inspection by the Borrower or any Lender at any reasonable time and from time to
time upon reasonable prior notice.

                                                                              78

          (h)  Notwithstanding anything in this Agreement to the contrary, no
assignment under Section 12.06(b) of any rights or obligations under or in
respect of the Loans or any Notes evidencing such Loans shall be effective
unless and until the Administrative Agent shall have recorded the assignment
pursuant to Section 12.06(g).  Upon its receipt of an Assignment and Acceptance
executed by an assigning Lender and an Assignee (and, in the case of an Assignee
that is not then a Lender or an Affiliate thereof, by the Borrower and the
Administrative Agent), together (unless the Assignee is an Affiliate or Approved
Fund of the Assignor) with payment to the Administrative Agent of a registration
and processing fee of $3,500, the Administrative Agent shall (i) promptly accept
such Assignment and Acceptance and (ii) on the effective date determined
pursuant thereto record the information contained therein in the Register and
give prompt notice of such acceptance and recordation to the Lenders and the
Borrower.  On or prior to such effective date, the assigning Lender shall
surrender any outstanding Notes held by it all or a portion of which are being
assigned, and the Borrower, at its own expense, shall, upon the request to the
Administrative Agent by the assigning Lender or the Assignee, as applicable,
execute and deliver to the Administrative Agent (in exchange for the outstanding
Notes of the assigning Lender, if any) a new Revolving Credit Note, Tranche A
Term Note, Tranche B Term Note and/or Tranche C Term Note, as the case may be
(such new Note to be a new Registered Note in the case of an assignment by or to
a Qualified Foreign Lender), to the order of such Assignee in an amount equal to
(i) in the case of a Revolving Credit Note, the amount of such Assignee's
Revolving Credit Commitment, (ii) in the case of a Tranche A Term Note, the
amount of such Assignee's Tranche A Term Loans, (iii) in the case of a Tranche B
Term Note, the amount of such Assignee's Tranche B Term Loan and (iv) in the
case of a Tranche C Term Note, the amount of such Assignee's Tranche C Term
Loan, and, if the assigning Lender has retained a Revolving Credit Commitment or
Term Loan hereunder, a new Revolving Credit Note, Tranche A Term Note, Tranche B
Term Note and/or Tranche C Term Note, as the case may be, to the order of the
assigning Lender in an amount equal to (i) in the case of a Revolving Credit
Note, the lesser of (A) the amount of such Lender's Revolving Credit Commitment
and (B) the aggregate principal amount of all Revolving Credit Loans made by
such Lender, (ii) in the case of a Tranche A Term Note, the amount of such
Lender's Tranche A Term Loans, (iii) in the case of a Tranche B Term Note, the
amount of such Lender's Tranche B Term Loan and (iv) in the case of a Tranche C
Term Note, the amount of such Lender's Tranche C Term Loan, in each case with
respect to the relevant Loan or Revolving Credit Commitment after giving effect
to such Assignment and Acceptance.  Any such new Notes shall be dated the
Closing Date, and shall otherwise be in the form of any Note replaced thereby.
Any Notes surrendered by the assigning Lender shall be returned by the
Administrative Agent to the Borrower marked "cancelled".

          12.7  Survival.  The obligations of the Borrower under Sections 5.01,
                --------
5.05, 5.06, 5.07 and 12.03 hereof, the obligations of each Guarantor under
Section 6.03 hereof, and the obligations of the Lenders under Section 11.05
hereof, shall survive the repayment of the Loans and Reimbursement Obligations
and the termination of the Revolving Credit Commitments and, in the case of any
Lender that may assign any interest in its Revolving Credit Commitment, Loans or
Letter of Credit Interest hereunder, shall survive the making of such
assignment, notwithstanding that such assigning Lender may cease to be a
"Lender" hereunder.  In addition, each representation and warranty made, or
deemed to be made by a notice of any extension of credit (whether by means of a
Loan or a Letter of Credit) herein or pursuant hereto shall survive the making
of such representation and warranty, and no Lender shall be deemed to have
waived, by reason of making any extension of credit hereunder (whether by means
of a Loan or a Letter of Credit) any Default that may arise by reason of such
representation or warranty proving to have been false or misleading,
notwithstanding that such Lender or the Administrative Agent may have had notice
or knowledge or reason to believe that such representation or warranty was false
or misleading at the time such extension of credit was made.

State of New York.  Each Obligor hereby submits to the nonexclusive jurisdiction

the Supreme Court of the State of New York sitting in New York County (including
its Appellate Division), and of any other appellate court in the State of New
York, for the purposes of all legal proceedings arising out of or relating to
this Agreement or the transactions contemplated hereby.  Each Obligor hereby
irrevocably waives, to the fullest extent permitted by applicable law, any
objection that it may now or hereafter have to the laying of the venue of any
such proceeding brought in such a court and any claim that any such proceeding
brought in such a court has been brought in an inconvenient forum.

                 -------------------------------------------------
the Borrower and the Company acknowledges that from time to time financial
advisory, investment banking and other services may be offered or provided to
the Borrower, the Company or one or more of their Subsidiaries (in connection
with this Agreement or otherwise) by any Lender or by one or more Subsidiaries
or affiliates of such Lender and each of the Borrower and the Company hereby
authorizes each Lender to share any information delivered to such Lender by the
Borrower, the Company and their Subsidiaries pursuant to this Agreement, or in
connection with the decision of such Lender to enter into this Agreement, to any
such Subsidiary or affiliate, it being understood that any such Subsidiary or
affiliate receiving such information shall be bound by the provisions of
paragraph (b) below as if it were a Lender hereunder.  Such authorization shall
survive the repayment of the Loans and Reimbursement Obligations and the
termination of the Revolving Credit Commitments.

          (b)  Each Lender and the Administrative Agent agrees (on behalf of
itself and each of its affiliates, directors, officers, employees and
representatives) to use reasonable precautions to keep confidential, in
accordance with their customary procedures for handling confidential information

FOR IMMEDIATE RELEASE

                    ADVANSTAR COMPLETES LARKIN ACQUISITION

                        Company revises Financing Plans

BOSTON, MA, August 9, 1999 - Advanstar, Inc., a worldwide business information
company, today announced it has completed its previously announced planned
acquisition of the trade show assets of The Larkin Group. Separately, Advanstar
indicated that it does not currently intend to move forward with an initial
public offering.

The Larkin Group produces 16 trade shows in New York City which serve the
fashion and fabric/textiles industries. Advanstar, through its MAGIC
international subsidiary, also owns and produces the world's largest fashion and
apparel trade show, MAGIC, held twice annually in Las Vegas.

In regard to Advanstar's financing plans, Robert L. Krakoff, Advanstar's
Chairman and Chief Executive Officer commented, "Over the past three years we
have grown significantly and increased the size and shareholder value of
Advanstar. We believe this growth will continue. After consulting with our
majority stockholder, we have determined that current public market valuations
for companies in the business-to-business communications sector do not reflect
the valuation levels that we think are appropriate for Advanstar given our
progress to date and our plans for the future. We will monitor the capital
markets and may move forward with an initial public offering if we believe
public market valuation levels become more appropriate."

"Management and our equity investors are very pleased with the development of
Advanstar since May 1996. EBITDA has increased from slightly over $20 million to
now approaching $100 million on a pro forma basis. We look forward to continuing
this growth," said Krakoff.

As in the past, Advanstar expects to continue to fund its growth strategy from
operating cash flow, additional borrowings and additional equity from its
majority stockholder, Hellman & Friedman Capital Partners III, L.P., a San
Francisco based private equity firm.
