                                  TENDER OFFER


         This Amendment No. 4 amends and supplements the Tender Offer Statement
on Schedule 14D-1, dated May 3, 1999, as amended by Amendment No. 1 dated May 5,
1999, Amendment No. 2 dated May 10, 1999, and Amendment No. 3 dated May 17, 1999
(collectively, the "Statement"), of InterVoice Acquisition Subsidiary III, Inc.,
a Nevada corporation (the "Purchaser") and a wholly owned subsidiary of
InterVoice, Inc., a Texas corporation ("Parent"), filed in connection with the
Purchaser's offer to purchase 9,158,155 shares of common stock, no par value
(the "Shares" or "Common Stock"), of Brite Voice Systems, Inc., a Kansas
corporation (the "Company"), as set forth in the Statement. All capitalized
terms not defined herein have the meanings given to them in the Offer to
Purchase dated May 3, 1999 (the "Offer to Purchase") filed as Exhibit (a)(1) to
the Statement, the Supplemental Letter dated May 10, 1999 filed as Exhibit
(a)(11) to the Statement, and the Supplemental Letter dated May 17, 1999 filed
as Exhibit (a)(12) to the Statement.

ITEM 4.  SOURCE AND AMOUNT OF FUNDS OR OTHER CONSIDERATION

         The response to Item 4 is hereby amended and supplemented as follows:

         "Parent and the Purchaser have entered into a credit agreement with
Bank of America National Trust and Savings Association ("Bank of America NT&SA")
and certain other financial institutions (the "Credit Agreement") pursuant to
which, subject to the terms and conditions thereof, Bank of America NT&SA will
provide the Purchaser financing in an aggregate amount of up to $150 million
(the "Facilities").

         The Facilities are guaranteed by Parent and each material existing and
future direct and indirect domestic subsidiary of InterVoice, excluding the
Purchaser; provided that the Company and its subsidiaries will not be required
to guarantee the financing until the consummation of the Merger.

         The Facilities consist of: (i) a $125 million tender facility which was
available to the Purchaser in order to fund the Offer and the Merger (the "Term
Loan Facility") and (ii) a $25 million revolving credit facility (the "Revolving
Credit Facility").

         The following is a summary of the principal terms of the Credit
Agreement. This summary is qualified in its entirety by reference to the Credit
Agreement, a copy of which has been filed as an exhibit to this Amendment No. 4.

         The Facilities will mature on August 29, 2003, and the Term Loan
Facility is subject to quarterly amortization with the first payment due on May
31, 2000. In addition, the Facilities are subject to certain mandatory
prepayments and commitment reductions tied to the sale of assets, the issuance
of debt, the issuance of equity and the generation of excess cash flow for a
fiscal year. Certain of these prepayment and commitment reduction requirements
are limited upon the satisfaction of certain financial ratios.

         The amounts borrowed pursuant to the Revolving Credit Facility and the
Term Loan Facility bear interest at a rate equal to either LIBOR plus the
applicable margin or the Alternate Base Rate (defined as the higher of (i) the
Bank of America NT&SA prime rate or (ii) the federal funds rate plus 0.50%) plus
the applicable margin. The applicable margin during the period from the closing
of the Facilities until receipt by the lenders of Parent's Form 10-Q for the
quarter ended November 30, 1999 will be 2.50% and 1.25% for LIBOR and Alternate
Base Rate loans, respectively. Thereafter, the applicable margin in each case
will be determined by reference to a ratio of Parent's funded debt to EBITDA (as
defined in the credit agreement) of not less than 1.75% and .50% for LIBOR and
Alternate Base Rate loans, respectively, and of not more than 2.50% and 1.25%
for LIBOR and Alternate Base Rate loans, respectively.

         The Credit Agreement contains certain representations and warranties,
certain negative and affirmative covenants, certain conditions and events of
default which are customarily required for similar financings. Such covenants
include, among others:

         o restrictions and limitations on liens and negative pledges;

         o limitations on mergers, consolidations and sales of assets;

         o limitations on incurrence of debt;

         o limitations on dividends, stock redemptions and the redemption and/or
           prepayment of other debt;

         o limitations on investments and acquisitions (other than the
           acquisition of the Company); and

         o limitations on capital expenditures.

         Key financial covenants based on Parent's consolidated financial
statements include minimum net worth, maximum leverage ratio and minimum fixed
charge coverage ratio.

         The financing requires a first priority perfected security interest in:

         o all of the capital stock of each of the material domestic
           subsidiaries of Parent (including, without limitation, the
           Purchaser), and 65% of the capital stock of each first tier foreign
           subsidiary of Parent, which capital stock shall not be subject to
           any other lien or encumbrance; and

        o  subject to permitted liens, all other present and future material
           assets and properties of Parent and its material domestic
           subsidiaries (including, without limitation, accounts receivable and
           proceeds, inventory, real property, machinery and equipment,
           contracts, trademarks, copyrights, patents, license rights and
           general intangibles), including, without limitation, the Company and
           its subsidiaries; provided that the Company and its subsidiaries
           shall not be required to pledge such assets and properties until
           completion of the Merger.

Without limiting the foregoing, but subject to the requirements of Regulation U
of the Federal Reserve Board, all capital stock of the Company owned by the
Purchaser or Parent shall be pledged as collateral for the financing.
Regulations of the Federal Reserve Board, including Regulation U, restrict the
extension or maintenance of credit for the purpose of buying or carrying margin
stock, including the Shares, if the credit is secured directly or indirectly by
margin stock. Such secured credit may not be extended or maintained in an amount
that exceeds the maximum loan value of all the direct and indirect collateral
securing the credit, including margin stock and other collateral. All financing
for the Offer and the Merger was structured so as to be in full compliance with
these regulations.

         In connection with the financing, the Purchaser has agreed to pay the
lenders certain fees, to reimburse the lenders for reasonable out-of-pocket fees
and expenses and to provide certain indemnities, as are customary for similar
financings.

         Parent anticipates that indebtedness incurred through borrowings under
the financing in connection with the Offer and the Merger will be repaid from a
variety of sources, which may include funds generated internally by Parent and
its subsidiaries and following the Merger, funds generated by the Company, bank
financing, and the public or private sale of debt or equity securities. No
decision has been made concerning the method Parent will employ to repay such
indebtedness. Such decision will be made based on Parent's review from time to
time of the advisability of particular actions, as well as on prevailing
interest rates and financial, market and other economic conditions and such
other factors as Parent may deem appropriate.

         Upon consummation of the Merger, the Purchaser will be merged into the
Company, which will then be obligated as the borrower under the Facilities."

ITEM 6.  INTEREST IN SECURITIES OF THE SUBJECT COMPANY.

         The response to Item 6 is hereby amended and supplemented as follows:

         At 12:00 midnight New York City time, on Tuesday, June 1, 1999, the
Offer expired. Based on information provided by the Depositary for the Offer,
Parent reported that as of the expiration of the Offer, 11,296,186
(approximately 92% of the outstanding Brite common stock) Shares were properly
tendered and not withdrawn pursuant to the Offer. The Purchaser has accepted for
payment, and has deposited with the Depositary cash in payment for, 9,158,155
Shares at the purchase price of $13.40 per Share in cash. As a result of the
consummation of the Offer, Purchaser will own approximately 75% of the
outstanding Shares.

ITEM 11. MATERIAL TO BE FILED AS EXHIBITS.

     The response to Item 11 is hereby amended and supplemented as follows:

(a)(14)  Press release dated June 2, 1999 announcing the expiration of the
         Offer.

                    INTERVOICE TENDER OFFER FOR BRITE SHARES
                              SUCCESSFULLY EXPIRES

DALLAS, TEXAS - JUNE 2, 1999 - InterVoice, Inc. announced today that it has
accepted for purchase 9,158,155 shares of common stock of Brite Voice Systems,
Inc. (Brite) tendered by Brite shareholders. More than eleven million shares
were tendered by Brite shareholders in response to InterVoice's tender offer to
purchase up to 9,158,155 shares, or approximately 75% of the outstanding shares
of Brite's stock. InterVoice currently anticipates that payment for the
9,158,155 Brite shares will occur promptly after proration of the tendered
shares. InterVoice will acquire the remaining 25% of the outstanding Brite
shares in a merger after the tender offer. Each Brite share will be exchanged
for share(s) of InterVoice valued at $13.40. The ratio of exchange will be
determined based on the average closing price of an InterVoice share for the
twenty-five trading days preceding the merger.

               INTERVOICE ANNOUNCES RESULTS OF BRITE TENDER OFFER

DALLAS, TEXAS - JUNE 9, 1999 - InterVoice, Inc. announced the final results of
the proration of its tender offer for 9,158,155 shares, or approximately 75% of
the outstanding common stock of Brite Voice Systems, Inc., at $13.40 per share.
As previously announced, the offer expired on June 1, 1999. The period for
receipt by the Depositary of shares tendered pursuant to notices of guaranteed
delivery expired on June 4, 1999. Based on the final count by the Depositary,
11,296,186 shares, or approximately 92% of the outstanding Brite common stock,
were tendered and not withdrawn prior to the expiration of the offer.
Accordingly, InterVoice will purchase from each tendering Brite stockholder
approximately 81.07% of all shares validly tendered, with adjustments to avoid
the purchase of fractional shares. Bank of America National Trust and Savings
association arranged and syndicated a $150 million credit facility to finance
the tender offer.

InterVoice will pay promptly for all purchased shares. Harris Trust Company of
New York is acting as InterVoice's agent in transmitting payment to tendering
stockholders. Brite stockholders whose shares are held in street name should
contact their brokers to verify receipt of payment for their shares accepted
for purchase in the tender offer. New certificates for all shares tendered and
not purchased by InterVoice will be returned promptly to tendering stockholders
or to an account maintained by their brokers at The Depository Trust Company.

InterVoice will acquire the remaining 25% of the outstanding Brite shares in a
merger whereby each Brite share will be exchanged for share(s) of InterVoice
valued at $13.40. The exchange ratio will be determined based on the average
closing price of an InterVoice share for 25 trading days preceding the merger.

and implemented by any Loan Party occur and such changes result in a change in
the method of the calculation of financial covenants under this Agreement, then
Parent, Borrower, Agent, and the Required Lenders agree to enter into
negotiations in order to amend such provisions of this Agreement so as to
equitably reflect such changes with the desired result that the criteria for
evaluating such covenants shall be the same after such changes as if such
changes had not been made. Until such time as such an amendment shall have been
executed and delivered by Parent, Borrower, Agent, and the Required Lenders, all
financial covenants, standards, and terms in this Agreement shall continue to be
calculated or construed as if such changes had not occurred.

     Section 2.1   Revolving Commitments. Subject to the terms and conditions of
this Agreement, each Lender severally agrees to make advances to Borrower from
time to time from and including the Closing Date to but excluding the Revolving
Maturity Date in an aggregate principal amount at any time outstanding up to but
not exceeding the amount of such Lender's Revolving Commitment as then in
effect; provided, however, (a) the Outstanding Revolving Credit applicable to a
Lender shall not at any time exceed such Lender's Revolving Commitment, and (b)
the Outstanding Revolving Credit of all of the Lenders shall not at any time
exceed the aggregate Revolving Commitments. Subject to the foregoing
limitations, and the other terms and provisions of this Agreement, Borrower may
borrow, prepay, and reborrow hereunder the amount of the Revolving Commitments
and may establish Base Rate Accounts and Libor Accounts thereunder and, until
the Revolving Maturity Date, Borrower may Continue Libor Accounts established
under the Revolving Loans or Convert Accounts established under the Revolving
Loans of one Type into Accounts of the other Type. Accounts of each Type under
the Revolving Loans made by each Lender shall be established and maintained at
such Lender's Applicable Lending Office for Revolving Loans of such Type.

     Section 2.2   Revolving Notes. The Revolving Loans made by a Lender shall
be evidenced by a single promissory note of Borrower, in substantially the form
of Exhibit A, payable to the order of such Lender, in the maximum principal
amount equal to such Lender's Revolving Commitment as originally in effect (or,
if greater, its Revolving Commitment as thereafter increased) and otherwise duly
completed.

     Section 2.3   Repayment of Revolving Loans. Borrower shall pay to Agent,
for the account of the Lenders, the prepayments of the Revolving Loans required
pursuant to Section 5.4(a) and the outstanding principal amount of all of the
Revolving Loans on the Revolving Maturity Date.

     Section 2.4   Use of Proceeds. Subject to the terms of this Agreement, the
proceeds of the Revolving Loans shall be used by Borrower (a) to make an advance
to Parent to repay its existing indebtedness due to NationsBank, N.A. under that
certain Amended and Restated Loan Agreement dated November 18, 1998, between
Parent and NationsBank, N.A., (b) to pay up to $10,000,000 of (i) the cash
portion of the consideration due in connection with the Brite Tender Offer and
the Brite

Merger and (ii) part of the fees and expenses incurred in connection with the
Brite Acquisition and the Brite Merger, and (c) otherwise for general corporate
purposes, including, without limitation, to finance working capital requirements
of Parent and its Subsidiaries, arising in the ordinary course of business, and
for payment of the Reimbursement Obligations; provided that notwithstanding any
other provision of this Agreement or any other Loan Document to the contrary,
the aggregate amount of all Loans made to Borrower on the Closing Date shall not
exceed the loan value (as determined by Agent and each Lender in its sole
discretion) of the Collateral securing the Loans on the Closing Date, including
the loan value of the Shares purchased and pledged to Agent on the Closing Date
(valued at fifty percent (50.0%) of market value), and all Loans made at any
time (including, without limitation, on the Closing Date) shall be made in
compliance with Regulation U.

     Section 2.5   Termination or Reduction of Revolving Commitments. Borrower
shall have the right to terminate fully or to reduce in part the unused portion
of the Revolving Commitments at any time and from time to time, provided that:
(a) Borrower shall not have the right to terminate or reduce in part any
unfunded portion of the Revolving Commitments that could or may be required to
be advanced by the Lenders to repay Reimbursement Obligations then outstanding;
(b) Borrower shall give Agent at least three (3) Business Days notice of each
such termination or reduction as provided in Section 5.3; and (c) each partial
reduction shall be in an aggregate amount at least equal to $5,000,000 or any
multiple $1,000,000 in excess thereof. The Revolving Commitments may not be
reinstated after they have been terminated or reduced.

     Section 2.6 Letters of Credit.

          (a)  Commitment to Issue. Borrower may utilize the Revolving
     Commitments by requesting that the Issuing Bank issue, and the Issuing
     Bank, subject to the terms and conditions of this Agreement, shall issue,
     standby or commercial documentary letters of credit for Borrower's account
     (such letters of credit being referred to herein as the "Letters of
     Credit", which may be for the account of any Loan Party); provided,
     however, (i) the aggregate amount of outstanding Letter of Credit
     Liabilities shall not at any time exceed $5,000,000, (ii) the Outstanding
     Revolving Credit shall not at any time exceed the maximum amount prescribed
     by Section 2.1, and (iii) the Outstanding Revolving Credit applicable to
     any Lender shall not at any time exceed the maximum amount for such Lender
     prescribed by Section 2.1. Upon the date of issue of a Letter of Credit,
     the Issuing Bank shall be deemed, without further action by any party
     hereto, to have sold to each Lender who holds a Revolving Commitment, and
     each such Lender shall be deemed, without further action by any party
     hereto, to have purchased from the Issuing Bank, a participation to the
     extent of such Lender's Commitment Percentage (calculated with respect to
     the Revolving Commitments) in such Letter of Credit and the related Letter
     of Credit Liabilities. Upon termination of the Revolving Commitments, any
     Letter of Credit then outstanding which has been fully cash collateralized
     to the satisfaction of Agent and the Issuing Bank shall no longer be
     considered a "Letter of Credit" covered by the terms of this Agreement and
     any participating interest heretofore granted by the Issuing Bank to the
     Lenders holding Revolving Commitments in such Letter of Credit shall be
     deemed terminated but the letter of credit fees payable hereunder shall
     continue to accrue to the Issuing Bank with respect to such Letter of
     Credit until the expiry thereof.



CREDIT AGREEMENT - Page 24

<PAGE>   31


          (b)  Letter of Credit Request Procedure. Borrower shall give Agent not
     less than three (3) Business Days prior notice (effective upon receipt)
     specifying the date of each Letter of Credit and the nature of the
     transactions to be supported thereby. Upon receipt of such notice Agent
     shall notify the Issuing Bank and each Lender who holds a Revolving
     Commitment of the contents thereof and of such Lender's Commitment
     Percentage of the amount of the proposed Letter of Credit. Each Letter of
     Credit (i) shall have an expiration date that does not extend beyond a date
     which is the lesser of (A) one (1) year from the date of issuance (or in
     the case of commercial documentary letters of credit ninety (90) days) or
     (B) thirty (30) days prior to the Revolving Maturity Date, (ii) shall be
     payable in Dollars, (iii) must support a transaction entered into or
     obligation arising in the ordinary course of business, (iv) must be
     satisfactory in form and substance to Agent and the Issuing Bank, and (v)
     shall be issued pursuant to such documentation as Agent and the Issuing
     Bank may require, including, without limitation, the Issuing Bank's
     standard form Letter of Credit Agreement; provided, that, in the event of
     any conflict between the terms of such agreement and the other Loan
     Documents, the terms of the other Loan Documents shall control.

          (c)  Letter of Credit Fees. Borrower will pay to Agent, for the
     account of each Lender holding a Revolving Commitment, a fee on such
     Lender's Commitment Percentage (calculated with respect to the Revolving
     Commitments only) of the daily average amount available for drawings under
     the Letters of Credit, such fee (i) to be paid in arrears on the first
     Quarterly Payment Date occurring after the date of the issuance of the
     first Letter of Credit and on each Quarterly Payment Date thereafter until
     the date of expiration or termination of all Letters of Credit and (ii) to
     be calculated at a rate per annum equal to the Libor Rate Margin applicable
     to the Revolving Loans on the basis of a year of 360 days and the actual
     number of days elapsed (including the first day but excluding the last
     day). After receiving any payment of any fees under this clause (c), Agent
     will promptly pay to each Lender that holds a Revolving Commitment the fees
     then due such Lender. Borrower will also pay to the Issuing Bank, for its
     account only, a fee on the daily average amount available to be drawn under
     all outstanding Letters of Credit, such fee (i) to be paid in arrears on
     the first Quarterly Payment Date occurring after the date of the issuance
     of the first Letter of Credit and on each Quarterly Payment Date thereafter
     until the date of expiration or termination of all Letters of Credit and
     (ii) to be calculated at a rate per annum equal to one-eighth of one
     percent (0.125%) on the basis of a year of 360 days and the actual number
     of days elapsed (including the first day but excluding the last day).
     Borrower will also pay to the Issuing Bank, for its account only, all
     customary fees for issuance, negotiation, amendment, or processing of the
     Letters of Credit.

          (d)  Funding of Drawings. Upon receipt from the beneficiary of any
     Letter of Credit of any demand for payment or other drawing under such
     Letter of Credit, the Issuing Bank shall so notify Agent and Agent shall so
     notify Borrower and each Lender that holds a Revolving Commitment as to the
     amount to be paid as a result of such demand or drawing and the respective
     payment date. Not later than 1:00 p.m. (Dallas, Texas time) on the
     applicable payment date if Borrower has not reimbursed the Issuing Bank for
     the amount paid as a result of such demand or drawing, each Lender will
     make available to Agent, at the Principal Office, in immediately available
     funds, an amount equal to such Lender's



CREDIT AGREEMENT - Page 25

<PAGE>   32


     Commitment Percentage (calculated based only on the Revolving Commitments)
     of the amount to be paid as a result of such demand or drawing which has
     not been reimbursed even if the conditions to a Loan under Article 8 have
     not been satisfied and Agent shall promptly pay such amounts to the Issuing
     Bank.

          (e)  Reimbursements. Borrower shall be irrevocably and unconditionally
     obligated to immediately reimburse the Issuing Bank (through Agent) for any
     amounts paid by the Issuing Bank upon any demand for payment or drawing
     under any Letter of Credit, without presentment, demand, protest, or other
     formalities of any kind. All payments on the Reimbursement Obligations
     shall be made to Agent not later than 1:00 p.m. (Dallas, Texas time) on the
     date of the corresponding payment under the Letter of Credit by the Issuing
     Bank; provided that Agent has provided notice to Borrower prior to 11:00
     a.m. (Dallas, Texas time) on such day that such payment is due. In the
     event such notice is received after 11:00 a.m. (Dallas, Texas time) on a
     Business Day, such payment shall be due not later than 1:00 p.m. (Dallas,
     Texas time) on the next succeeding Business Day. Subject to the other terms
     and conditions of this Agreement, such reimbursement may be made by
     Borrower requesting a Revolving Loan in accordance with Section 5.1, the
     proceeds of which shall be credited against Borrower's Reimbursement
     Obligations. Agent will pay to each Lender participating in a Letter of
     Credit such Lender's Commitment Percentage (calculated based only on the
     Revolving Commitments) of all amounts received from Borrower for
     application in payment, in whole or in part, to the Reimbursement
     Obligation in respect of any Letter of Credit, but only to the extent such
     Lender has made payment to Agent in respect of such Letter of Credit
     pursuant to clause (d) of this Section 2.6.

          (f)  Reimbursement Obligations Absolute. The Reimbursement Obligations
     of Borrower under this Agreement shall be absolute, unconditional, and
     irrevocable, and shall be performed strictly in accordance with the terms
     of the Loan Documents under all circumstances whatsoever and Borrower
     hereby waives any defense to the payment of the Reimbursement Obligations
     based on any circumstance whatsoever, including, without limitation, in
     either case, the following circumstances: (i) any lack of validity or
     enforceability of any Letter of Credit or any other Loan Document; (ii) the
     existence of any claim, set-off, counterclaim, defense, or other rights
     which any Loan Party or any other Person may have at any time against any
     beneficiary of any Letter of Credit, the Issuing Bank, Agent, any Lender,
     or any other Person, whether in connection with any Loan Document or any
     unrelated transaction; (iii) any statement, draft, or other documentation
     presented under any Letter of Credit proving to be forged, fraudulent,
     invalid, or insufficient in any respect or any statement therein being
     untrue or inaccurate in any respect whatsoever; (iv) payment by the Issuing
     Bank under any Letter of Credit against presentation of a draft or other
     document that does not comply with the terms of such Letter of Credit; or
     (v) any other circumstance whatsoever, whether or not similar to any of the
     foregoing.

          (g)  Assumption of Risk by Borrower. As among Borrower and the
     Lenders, Borrower assumes all risks of the acts and omissions of, or misuse
     of any of the Letters of Credit by, the respective beneficiaries of such
     Letters of Credit. In furtherance and not in



CREDIT AGREEMENT - Page 26

<PAGE>   33

     limitation of the foregoing, subject to the provisions of the applications
     for the issuance of Letters of Credit, the Lenders, the Issuing Bank, and
     Agent shall not be responsible for:

               (i)    the form, validity, sufficiency, accuracy, genuineness, or
          legal effect of any document submitted by any Person in connection
          with the application for and issuance of and presentation of drafts
          with respect to any of the Letters of Credit, even if it should prove
          to be in any or all respects invalid, insufficient, inaccurate,
          fraudulent, or forged;

               (ii)   the validity or sufficiency of any instrument transferring
          or assigning, or purporting to transfer or assign, any Letter of
          Credit or the rights or benefits thereunder or proceeds thereof, in
          whole or in part, which may prove to be invalid or ineffective for any
          reason;

               (iii)  the failure of the beneficiary of any Letter of Credit to
          comply duly with conditions required in order to draw upon such Letter
          of Credit;

               (iv)   errors, omissions, interruptions, or delays in
          transmission or delivery of any messages, by mail, cable, telegraph,
          telex, or otherwise, whether or not they be in cipher;

               (v)    errors in interpretation of technical terms;

               (vi)   any loss or delay in the transmission or otherwise of any
          document required in order to make a drawing under any Letter of
          Credit or of the proceeds thereof;

               (vii)  the misapplication by the beneficiary of any Letter of
          Credit of the proceeds of any drawing under such Letter of Credit; or

               (viii) any consequences arising from causes beyond the control of
          any Lender or the Issuing Bank, including, without limitation, any act
          of any Governmental Authority.

None of the foregoing shall affect, impair, or prevent the vesting of any of
the Lenders', the Issuing Bank's, or Agent's rights or powers under this
Section 2.6. Borrower shall have a claim against the Issuing Bank, and the
Issuing Bank shall be liable to Borrower, to the extent of any direct (but not
indirect, consequential, or punitive) damages suffered by Borrower which
Borrower proves in a final nonappealable judgment were caused by (A) the
Issuing Bank's willful misconduct or gross negligence in determining whether
documents presented under any Letter of Credit complied with the terms thereof
or (B) the Issuing Bank's willful failure to pay under any Letter of Credit
after presentation to it of documentation strictly complying with the terms and
conditions of such Letter of Credit. The Issuing Bank may accept documents that
appear on their face to be in order, without responsibility for further
investigation, regardless of any notice or information to the contrary.

Type established under the Term Loans made by each Lender shall be made and
maintained at such Lender's Applicable Lending Office for Accounts of such Type.
The amount of the Term Commitment shall be reduced on the Closing Date by the
amount of the Term Loans made on the Closing Date, and the remaining Term
Commitment shall terminate on the Brite Merger Date.

     Section 3.2   Term Notes. Each Term Loan made by a Lender shall be
evidenced by a single promissory note of Borrower in substantially the form of
Exhibit B, payable to the order of such Lender, in the maximum principal amount
equal to its Term Commitment and otherwise duly completed.

     Section 3.3   Repayment of Term Loans. Borrower shall pay to Agent for the
account of the Lenders who hold Term Loans the aggregate principal amount of the
Term Loans as follows:

          (a)  Fourteen (14) consecutive quarterly principal installments due

          (a)  during the period that such Loan or portion thereof is
     outstanding as a Base Rate Account, the Base Rate, plus the Base Rate
     Margin; and

If Borrower fails to deliver such certificate with respect to any Fiscal Quarter
which sets forth the Leverage Ratio within the period of time required by
Section 10.1(d): (y) the Base Rate Margin shall automatically be adjusted to one
and one-quarter (1.25%) per annum, and (z) the Libor Rate Margin (for Interest
Periods commencing after the applicable Adjustment Date) shall automatically be
adjusted to two and one-half percent (2.50%) per annum. The automatic
adjustments provided for in the preceding sentence shall remain in effect until
subsequently adjusted prospectively in accordance herewith upon delivery of the
required certificate.

     Section 4.3   Payment Dates. Accrued interest on the Loans shall be due and
payable as follows: (a) in the case of Loans outstanding as Base Rate Accounts,
on each Quarterly Payment Date and on the Maturity Date of such Loan; and (b) in
the case of Loans outstanding as Libor Accounts and with respect to each such
Account, on (i) the last day of the Interest Period with



CREDIT AGREEMENT - Page 30

respect thereto, (ii) in the case of an Interest Period greater than three
months, at three-month intervals after the first day of such Interest Period,
and (iii) on the Maturity Date of such Loan.

     Section 4.4   Default Interest. Notwithstanding anything to the contrary
contained in this Agreement, during the existence of an Event of Default,
Borrower will pay to Agent for the account of each Lender interest at the
applicable Default Rate on any principal of any Loan made by such Lender, any
Reimbursement Obligation, and (to the fullest extent permitted by law) any other
amount payable by Borrower under any Loan Document to or for the account of
Agent or such Lender.

     Section 4.5   Conversions and Continuations of Accounts. Subject to Section
5.2, Borrower shall have the right from time to time to Convert all or part of
any Base Rate Account in existence under a Loan into a Libor Account under the
same Loan or to continue Libor Accounts in existence under a Loan as Libor
Accounts under the same Loan, provided that: (a) Borrower shall give Agent
notice of each such Conversion or Continuation as provided in Section 5.3; (b)
subject to Section 6.3, a Libor Account may only be Converted on the last day of
the Interest Period therefor; and (c) except for Conversions into Base Rate
Accounts, no Conversions or Continuations shall be made without the consent of
Agent and the Required Lenders at any time during the existence of a Default.

     Section 4.6   Commitment Fee. Borrower agrees to pay to Agent for the
account of each Lender a commitment fee (determined according to the provisions
of Section 4.2) on the daily average unused amount of such Lender's Total
Commitment for the period from and including the Closing Date to and including
the Maturity Date, at a per annum rate equal to the Commitment Fee Rate,
provided that for purposes of calculating such fee the amount of outstanding
Letters of Credit shall constitute use of the Total Commitment. Accrued
Commitment Fees under this Section shall be payable in arrears on each Quarterly
Payment Date and on the Maturity Date.

     Section 4.7   Computations. Interest and fees payable by Borrower hereunder
and under the other Loan Documents shall be computed on the basis of a year of
360 days and the actual number of days elapsed (including the first day but
excluding the last day) in the period for which interest is payable unless such
calculation would result in a rate that exceeds the Maximum Rate, in which case
interest shall be calculated on the basis of a year of 365 or 366 days, as the
case may be. Notwithstanding anything to the contrary contained in this Section,
interest payable by Borrower hereunder and under the other Loan Documents with
respect to the Base Rate shall be computed on the basis of a year of 365 or 366
days, as the case may be, and the actual number of days elapsed (including the
first day but excluding the last day) in the period for which interest is
payable. Each determination of an interest rate by Agent shall be conclusive and
binding on Borrower and the Lenders in the absence of manifest error. Agent
will, at the request of Borrower or any Lender, deliver to Borrower or such
Lender, as the case may be, a statement showing the quotations used by Agent in
determining any interest rate and the resulting interest rate.

     Section 4.8   Agent Fee. Each of Parent and Borrower agrees to pay to Agent
on the Closing Date and on each anniversary thereof the administrative fee
described in the Agent's Letter.

     Notwithstanding the foregoing, Borrower may give an effective notice of
     borrowing of Revolving Loans as a Base Rate Account in accordance with
     Section 2.6(e) not later than 10:00 a.m. (Dallas, Texas time) on the
     Business Day of the proposed borrowing if the proceeds of such borrowing
     will be used to satisfy Reimbursement Obligations. Any notices of the type
     described in this Section which are received by Agent after the applicable
     time set forth above on a Business Day shall be deemed to be received and
     shall be effective on the next Business Day. Each such notice of
     termination or reduction shall specify the applicable Commitments to be
     affected and the amount of the Commitments to be terminated or reduced.
     Each such notice of borrowing, Conversion, Continuation, or prepayment
     shall be in the form of Exhibit G, appropriately completed by an authorized
     representative of Borrower, and shall specify (a) the Loans to be borrowed
     or prepaid or the Accounts to be Converted or Continued; (b) the amount
     (subject to Section 5.2) to be borrowed, Converted, Continued, or prepaid;
     (c) in the case of a Conversion, the Type of Account to result from such
     Conversion; (d) in the case of a borrowing, the Type of Account or Accounts
     to be applicable to such borrowing and the amounts thereof; (e) in the
     event a Libor Account is selected, the duration of the Interest Period
     therefor; and (f) the date of borrowing, Conversion, Continuation, or
     prepayment (which shall be a Business Day).

          (b)  Any notices by Borrower of the type described in this Section may
     be made orally or in writing and, if made orally, must be confirmed
     immediately in writing (which may be by telecopy, provided that such
     telecopy is promptly followed by delivery of an original signed notice) on
     the same Business Day on which such oral notice is given; provided that any
     such oral notice shall be deemed to be controlling and proper notice in the
     event of a discrepancy with or failure to receive a confirming written
     notice. Agent shall notify the Lenders of the contents of each such notice
     on the date of its receipt of the same or, if received after the applicable
     time set forth above on a Business Day, on the next Business Day. In the
     event Borrower fails to select the Type of Account applicable to a Loan, or
     the duration of any Interest Period for any Libor Account, within the time
     period and otherwise as provided in this Section, such Account (if
     outstanding as a Libor Account) will be automatically Converted into a Base
     Rate Account on the last day of the Interest Period for such Account or (if
     outstanding as a Base Rate Account) will remain as, or (if not then
     outstanding) will be made as, a Base Rate Account. Borrower may not borrow
     any

     Loans as a Libor Account, Convert any Base Rate Accounts into Libor
     Accounts, or Continue any Libor Account as a Libor Account if the
     Applicable Rate for such Libor Accounts would exceed the Maximum Rate.

     Section 5.4   Prepayments.

          (a)  Mandatory.

               (i)    Revolving Loans. If at any time the Outstanding Revolving
          Credit exceeds the aggregate Revolving Commitments, Borrower shall,
          within one (1) Business Day after the occurrence thereof, prepay the
          outstanding Revolving Loans by the amount of such excess.

               (ii)   Prepayments from Asset Dispositions. Immediately upon
          receipt by Parent or any of its Subsidiaries of the Net Proceeds of
          any Asset Disposition, Borrower shall make a prepayment in respect of
          the Obligations equal to the amount of such Net Proceeds as provided
          by Section 5.4(a)(vi) or if the Term Loans have been fully repaid,
          such prepayment shall be applied to the Revolving Loans and the
          Revolving Commitments shall be permanently reduced by a corresponding
          amount; provided, however, that if such Asset Disposition occurs in
          the ordinary course of business of such Person and if no Default is in
          existence, Borrower shall not be required to make such prepayment to
          the extent that the Net Proceeds from any such Asset Disposition are
          less than $1,000,000 and the Net Proceeds from all such Asset
          Dispositions during the term of this Agreement do not exceed
          $5,000,000 in the aggregate; provided, further, however, that if
          Parent's Leverage Ratio, as reported pursuant to the most recent
          Compliance Certificate delivered to Agent and the Lenders pursuant to
          Section 10.1(c), is less than or equal to 1.0 to 1.0, no such
          prepayment will be required if and to the extent that the Net Proceeds
          of any such Asset Disposition, other than a disposition of any line of
          business or operations of any Loan Party, are fully re-invested in
          productive assets (including, but not limited to, software licenses)
          used in the ordinary course of such Person's business within one
          hundred twenty (120) days of the receipt of such Net Proceeds.

               (iii)  Prepayments from Debt Offerings. In the event that Parent
          or any Subsidiary of Parent issues any debt Securities (including,
          without limitation, any subordinated debt Securities) (other than Debt
          permitted by Section 11.1) no later than the third Business Day
          following the date of receipt of the proceeds from such issuance,
          Borrower shall make a prepayment in respect of the Obligations equal
          to the amount of the Net Proceeds in prepayment of the Loans as
          provided in Section 5.4(a)(vi).

               (iv)   Prepayments from Equity Offerings. At any time Parent's
          Leverage Ratio as reported pursuant to the most recent Compliance
          Certificate delivered to Agent and the Lenders pursuant to Section
          10.1(c) is greater than 1.00 to 1.00, in the event that Parent or any
          Subsidiary of Parent issues Capital Stock in any public



CREDIT AGREEMENT - Page 34

<PAGE>   41


          offering or private placement or receives an additional capital
          contribution in respect of existing Capital Stock or other Securities
          (including, without limitation, debt Securities), other than such
          issuance or placement made exclusively in payment of, or funding for,
          a Permitted Acquisition, part of any employee or executive stock
          option plan, stock purchase plan, or restricted stock plan (or capital
          contribution in respect thereof) or issued in exchange for outstanding
          debt or equity securities, no later than the third Business Day
          following the date of receipt of the proceeds from such issuance,
          Borrower shall make a prepayment in respect of the Obligations equal
          to the Net Proceeds of such issuance, in prepayment of the Loans as
          provided in Section 5.4(a)(vi).

               (v)    Prepayments from Excess Cash Flow. Commencing with
          Parent's Fiscal Year ending February 28, 2000, and continuing each
          Fiscal Year ending thereafter, if Parent's Leverage Ratio calculated
          as of such Fiscal Year end for the preceding four Fiscal Quarters is
          greater than 1.00 to 1.00, Borrower shall, within one hundred twenty
          (120) days of such Fiscal Year end, make a prepayment of the Loans and
          other Obligations then outstanding in an amount equal to the lesser of
          (A) seventy-five percent (75.0%) of the remainder of Parent's Excess
          Cash Flow minus all prepayments made pursuant to this clause (v) prior
          to the date of such calculation or (B) an amount necessary to reduce
          Parent's Leverage Ratio as calculated above, but after giving effect
          to such prepayment, to 1.00 to 1.00, such prepayment to be applied as
          provided in Section 5.4(a)(vi).

               (vi)   Application of Proceeds of Prepayments. All prepayments of
          Term Loans pursuant to this Section 5.4(a) shall be accompanied by an
          appropriate notice of prepayment in accordance with Section 5.3 and
          shall be applied to the Term Loans in the inverse order of maturity of
          the remaining installments of principal of the Term Loans until the
          Term Loans are paid in full. Upon payment of the Term Loans in full,
          no further prepayment will be required pursuant to the terms of this
          Section 5.4(a), other than as provided in Section 5.4(a)(i) and
          Section 5.4(a)(ii).

          (b)  Optional. Subject to Section 5.2 and the provisions of this
     clause (b), Borrower may, at any time and from time to time without premium
     or penalty upon prior notice to Agent as specified in Section 5.3, prepay
     or repay any Loan in full or in part. Any optional prepayment of the Term
     Loans shall be accompanied with accrued interest on the amount prepaid to
     the date of prepayment. Any partial prepayments of the Term Loans shall be
     applied to installments due under the Term Loans, pro rata with respect to
     each remaining installment of principal. Loans outstanding as a Libor
     Account may be prepaid or repaid only on the last day of the Interest
     Period applicable thereto unless Borrower pays to Agent, for the account of
     the applicable Lenders, any amounts due under Section 6.5 as a result of
     such prepayment or repayment.

     Section 5.5   Method of Payment. Except as otherwise expressly provided
herein, all payments of principal, interest, and other amounts to be made by
Borrower or any other Loan Party under the Loan Documents shall be made to Agent
at the Principal Office for the account of each



CREDIT AGREEMENT - Page 35

<PAGE>   42

Lender's Applicable Lending Office in Dollars and in immediately available
funds, without set-off, deduction, or counterclaim, not later than 1:00 p.m.
(Dallas, Texas time) on the date on which such payment shall become due (each
such payment made after such time on such due date to be deemed to have been
made on the next succeeding Business Day). Borrower shall, at the time of making
each such payment, specify to Agent the sums payable under the Loan Documents to
which such payment is to be applied (and in the event that Borrower fails to so
specify, or if an Event of Default is in existence, Agent may apply such payment
to the Obligations in such order and manner as it may elect in its sole
discretion, subject to Section 5.6 and provided that when applying any such
amounts to any Loans, Loans outstanding as Base Rate Accounts shall be prepaid
in full prior to any application to Loans subject to Libor Accounts). Each
payment received by Agent under any Loan Document for the account of a Lender
shall be paid to such Lender by 3:00 p.m. (Dallas, Texas time) on the date the
payment is deemed made to Agent in immediately available funds, for the account
of such Lender's Applicable Lending Office. Whenever any payment under any Loan
Document shall be stated to be due on a day that is not a Business Day, such
payment may be made on the next succeeding Business Day, and such extension of
time shall in such case be included in the computation of the payment of
interest and commitment fee, as the case may be.

     Section 5.6   Pro Rata Treatment. Except to the extent otherwise provided
herein: (a) each Loan shall be made by the Lenders holding Commitments for such
Loan, each payment of commitment fees under Section 4.6 and letter of credit
fees under Section 2.6(c) shall be made for the account of the Lenders holding
Revolving Commitments and each termination or reduction of the Commitments shall
be applied to the Commitments of the Lenders holding the applicable Commitments,
pro rata according to their respective Commitment Percentages (calculated with
respect to the Commitments for the Loans in question only); (b) the making,
Conversion, and Continuation of Accounts of a particular Type (other than
Conversions provided for by Section 6.4) shall be made pro rata among the
Lenders holding Accounts of such Type according to their respective Commitment
Percentages (calculated with respect to the Commitments for the Loans in
question only); (c) each payment and prepayment of principal of or interest on
Loans or Reimbursement Obligations by Borrower shall be made to Agent for the
account of the Lenders holding such Loans or Reimbursement Obligations (or
participation interests therein) pro rata in accordance with the respective
unpaid principal amounts of such Loans or participation interests held by such
Lenders; provided that as long as no default in the payment of interest exists,
payments of interest made when Lenders are holding different types of Accounts
applicable to the same Loan as a result of the application of Section 6.4, shall
be made to the Lenders in accordance with the amount of interest owed to each;
and (d) the Lenders holding Revolving Commitments shall purchase from the
Issuing Bank participations in the Letters of Credit to the extent of their
respective Commitment Percentages (calculated only with respect to the Revolving
Commitments). All payments of the Term Loans shall be applied pro rata with
respect to each installment of principal. If at any time payment, in whole or in
part, of any amount distributed by Agent hereunder is rescinded or must
otherwise be restored or returned by Agent as a preference, fraudulent
conveyance, or otherwise under any bankruptcy, insolvency, or similar law, then
each Person receiving any portion of such amount agrees, upon demand, to return
the portion of such amount it has received to Agent.

     Section 5.7   Sharing of Payments. If a Lender shall obtain payment of any
principal of or interest on any of the Obligations due to such Lender hereunder
directly (and not through Agent)



CREDIT AGREEMENT - Page 36

<PAGE>   43

through the exercise of any right of set-off, banker's lien, counterclaim, or
similar right, or otherwise, it shall promptly purchase from the other Lenders
participations in the Obligations held by the other Lenders 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 payment pro rata in
accordance with the unpaid principal of and interest on the Obligations then due
to each of them. To such end, all of the Lenders shall make appropriate
adjustments among themselves (by the resale of participations sold or otherwise)
if all or any portion of such excess payment is thereafter rescinded or must
otherwise be restored. Borrower agrees, to the fullest extent it may effectively
do so under applicable law, that any Lender so purchasing a participation in the
Obligations held by the other Lenders 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 Obligations in
the amount of such participation. 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, liability, or obligation of Borrower.

     Section 5.8   Non-Receipt of Funds by Agent.

          (a)  Unless Agent shall have been notified by a Lender or Borrower
     (the "Payor") prior to the date on which such Lender is to make payment to
     Agent hereunder or Borrower is to make a payment to Agent, for the account
     of one or more of Agent or the Lenders, as the case may be (such payment
     being herein called the "Required Payment"), which notice shall be
     effective upon receipt, that the Payor does not intend to make the Required
     Payment to Agent, Agent may assume that the Required Payment has been made
     and may, in reliance upon such assumption (but shall not be required to),
     make the amount thereof available to the intended recipient on such date
     and, if the Payor has not in fact made the Required Payment to Agent, (i)
     the recipient of such payment shall, on demand, pay to Agent the amount
     made available to it together with interest thereon in respect of the
     period commencing on the date such amount was so made available by Agent
     until the date Agent recovers such amount at a rate per annum equal to the
     Federal Funds Rate for such period, and (ii) Agent shall be entitled to
     offset against any and all sums to be paid to such recipient, the amount
     calculated in accordance with the foregoing clause (a).

          (b)  The Commitments and other obligations of the Lenders under any
     Loan Document are several. The default by any Lender in making a Loan in
     accordance with its Commitment shall not relieve the other Lenders of their
     obligations under any Loan Document. In the event of any default by any
     Lender in making any Loan, each nondefaulting Lender shall be obligated to
     make its Loan but shall not be obligated to advance the amount which the
     defaulting Lender was required to advance hereunder. No Lender shall be
     responsible for any act or omission of any other Lender.

     Section 5.9   Participation Obligations Absolute; Failure to Fund
Participation. The obligations of a Lender holding a Revolving Commitment to
fund its participation in the Letters of Credit in accordance with the terms
hereof shall be absolute, unconditional, and irrevocable and shall be performed
strictly in accordance with the terms of the Loan Documents under all
circumstances whatsoever, including, without limitation, the following
circumstances: (a) any lack of validity of



CREDIT AGREEMENT - Page 37

<PAGE>   44

any Loan Document; (b) the occurrence of any Default; (c) the existence of any
claim, set-off, counterclaim, defense, or other right which such Lender, any
Loan Party, or any other Person may have; (d) the occurrence of any event that
has or could reasonably be expected to have a Material Adverse Effect on any
Loan Party; (e) the failure of any condition to a Loan under Article 8 to be
satisfied; (f) the fact that after giving effect to the funding of the
participation the Outstanding Revolving Credit may exceed the aggregate
Revolving Commitments; or (g) any other circumstance whatsoever, whether or not
similar to any of the foregoing. If a Lender fails to fund its participation in
a Letter of Credit as required hereby, such Lender shall, subject to the
foregoing proviso, remain obligated to pay to Agent the amount it failed to fund
on demand together with interest thereon in respect of the period commencing on
the date such amount should have been funded until the date the amount was
actually funded to Agent at a rate per annum equal to the Federal Funds Rate for
such period and Agent shall be entitled to offset against any and all sums to be
paid to such Lender hereunder the amount due Agent under this sentence.


                                    ARTICLE 6

                            Change in Circumstances

     Section 6.1   Increased Cost and Reduced Return.

          (a)  Increased Cost. If, after the Closing Date, any Regulatory Change
     or compliance by any Lender (or its Applicable Lending Office) with any
     request or directive (whether or not having the force of law) of any
     Governmental Authority, central bank, or comparable agency:

               (i)    shall subject such Lender (or its Applicable Lending
          Office) to any tax, duty, or other charge with respect to any Libor
          Accounts, its Notes, or its obligation to make Libor Accounts, or
          change the basis of taxation of any amounts payable to such Lender (or
          its Applicable Lending Office) under this Agreement or its Notes in
          respect of any Libor Accounts (other than franchise taxes or taxes
          imposed on or measured by the net income of such Lender by the
          jurisdiction in which such Lender is organized, has its principal
          office or such Applicable Lending Office, or is doing business);

               (ii)   shall impose, modify, or deem applicable any reserve,
          special deposit, assessment, or similar requirement (other than the
          Reserve Requirement utilized in the determination of the Adjusted
          Libor Rate) relating to any extensions of credit or other assets of,
          or any deposits with or other liabilities or commitments of, such
          Lender (or its Applicable Lending Office), including the Commitments
          of such Lender hereunder; or

               (iii)  shall impose on such Lender (or its Applicable Lending
          Office) or the London interbank market any other condition affecting
          this Agreement or its Notes or any of such extensions of credit or
          liabilities or commitments;



CREDIT AGREEMENT - Page 38

<PAGE>   45
     and the result of any of the foregoing is to increase the cost to such
     Lender (or its Applicable Lending Office) of making, Converting into,
     Continuing, or maintaining any Libor Accounts or to reduce any sum received
     or receivable by such Lender (or its Applicable Lending Office) under this
     Agreement or its Notes with respect to any Libor Accounts, then Borrower
     shall pay to such Lender on demand such amount or amounts as will
     compensate such Lender for such increased cost or reduction. If any Lender
     requests compensation by Borrower under this Section 6.1(a), Borrower may,
     by notice to such Lender (with a copy to Agent), suspend the obligation of
     such Lender to make or maintain Libor Accounts, or to Convert Base Rate
     Accounts into Libor Accounts, until the event or condition giving rise to
     such request ceases to be in effect (in which case the provisions of
     Section 6.4 shall be applicable); provided that such suspension shall not
     affect the right of such Lender to receive the compensation so requested.

          (b)  Capital Adequacy. If, after the date hereof, any Lender shall
     have determined that any Regulatory Change has or would have the effect of
     reducing the rate of return on the capital of such Lender or any
     corporation controlling such Lender as a consequence of such Lender's
     obligations hereunder to a level below that which such Lender or such
     corporation could have achieved but for such adoption, change, request, or
     directive (taking into consideration its policies with respect to capital
     adequacy) by an amount deemed by such Lender to be material, then from time
     to time upon demand, Borrower shall pay to such Lender such additional
     amount or amounts as will compensate such Lender for such reduction.

          (c)  Claims Under this Section 6.1. Each Lender shall promptly notify
     Borrower and Agent of any event of which it has knowledge, occurring after
     the date hereof, which will entitle such Lender to compensation pursuant to
     this Section 6.1 and will designate a different Applicable Lending Office
     if such designation will avoid the need for, or reduce the amount of, such
     compensation and will not, in the judgment of such Lender, be otherwise
     disadvantageous to it. Any Lender claiming compensation under this Section
     6.1 shall furnish to Borrower and Agent a statement setting forth the
     additional amount or amounts to be paid to it hereunder which shall be
     conclusive in the absence of manifest error. In determining such amount,
     such Lender may use any reasonable averaging and attribution methods.

     Section 6.2   Limitation on Libor Accounts. If on or prior to the first day
of any Interest Period for any Libor Account:

          (a)  Agent determines (which determination shall be conclusive) that
     by reason of circumstances affecting the relevant market, adequate and
     reasonable means do not exist for ascertaining the Libor Rate for such
     Interest Period; or

          (b)  the Required Lenders determine (which determination shall be
     conclusive) and notify Agent that the Adjusted Libor Rate will not
     adequately and fairly reflect the cost to the Lenders of funding Libor
     Accounts for such Interest Period;



CREDIT AGREEMENT - Page 39

<PAGE>   46


then Agent shall give Borrower prompt notice thereof specifying the amounts or
periods, and so long as such condition remains in effect, the Lenders shall be
under no obligation to make additional Libor Accounts, Continue Libor Accounts,
or to Convert Base Rate Accounts into Libor Accounts and Borrower shall, on the
last day(s) of the then current Interest Period(s) for the outstanding Libor
Accounts, either prepay such Libor Accounts or Convert such Libor Accounts into
Base Rate Accounts in accordance with the terms of this Agreement.

     Section 6.3   Illegality. Notwithstanding any other provision of this
Agreement, in the event that it becomes unlawful for any Lender or its
Applicable Lending Office to make, maintain, or fund Libor Accounts hereunder,
then such Lender shall promptly notify Borrower and Agent thereof and such
Lender's obligation to make or Continue Libor Accounts and to Convert Base Rate
Accounts into Libor Accounts shall be suspended until such time as such Lender
may again make, maintain, and fund Libor Accounts (in which case the provisions
of Section 6.4 shall be applicable).

     Section 6.4   Treatment of Affected Accounts. If the obligation of any
Lender to make a particular Libor Account or to Continue, or to Convert Base
Rate Accounts into, Libor Accounts shall be suspended pursuant to Section 6.1 or
Section 6.3 (Accounts of such Type being herein called "Affected Accounts"),
such Lender's Affected Accounts shall be automatically Converted into Base Rate
Accounts on the last day(s) of the then current Interest Period(s) for the
Affected Accounts (or, in the case of a Conversion required by Section 6.3, on
such earlier date as such Lender may specify to Borrower with a copy to Agent)
and, unless and until such Lender gives notice as provided below that the
circumstances specified in Section 6.1 or Section 6.3 that gave rise to such
Conversion no longer exist:

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

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

If such Lender gives notice to Borrower (with a copy to Agent) that the
circumstances specified in Section 6.1 or Section 6.3 that gave rise to the
Conversion of such Lender's Affected Accounts no longer exist (which such Lender
agrees to do promptly upon such circumstances ceasing to exist) at a time when
Libor Accounts made by other Lenders are outstanding, such Lender's Base Rate
Accounts shall be automatically Converted, on the first day(s) of the next
succeeding Interest Period(s) for such outstanding Libor Accounts, to the extent
necessary so that, after giving effect thereto, all Accounts held by the Lenders
holding Libor Accounts and by such Lender are held pro rata (as to principal
amounts, Types, and Interest Periods) in accordance with their respective
Commitment Percentages.

     Section 6.5   Compensation. Upon the request of any Lender, Borrower shall
pay to such Lender such amount or amounts as shall be sufficient (in the
reasonable opinion of such Lender) to



CREDIT AGREEMENT - Page 40

<PAGE>   47


compensate it for any loss, cost, or expense (including, without limitation,
loss of anticipated profits and any such amounts incurred in connection with
syndication of the Loans) incurred by it as a result of:

          (a)  any payment, prepayment, or Conversion by Borrower of a Libor
     Account for any reason (including, without limitation, the acceleration of
     the Loans pursuant to Section 13.2) on a date other than the last day of
     the Interest Period for such Libor Account; or

          (b)  any failure by Borrower for any reason (including, without
     limitation, the failure of any condition precedent specified in Article 8
     to be satisfied) to borrow, Convert, Continue, or prepay a Libor Account on
     the date for such borrowing, Conversion, Continuation, or prepayment
     specified in the relevant notice of borrowing, prepayment, Continuation, or
     Conversion under this Agreement.

Notwithstanding the foregoing provisions of this Section 6.5, if at any time the
mandatory prepayment of Term Loans pursuant to Section 5.4(a) would result in
Borrower incurring breakage costs under this Section 6.5 as a result of Libor
Accounts being prepaid other than on the last day of an Interest Period
applicable thereto (the "Affected Libor Accounts"), then Borrower may in its
sole discretion initially deposit a portion (up to 100%) of the amounts that
otherwise would have been paid in respect of the Affected Libor Accounts with
Agent (which deposit, after giving effect to interest to be earned on such
deposit prior to the last day of the relevant Interest Periods, must be equal in
amount to the amount of Affected Libor Accounts not immediately prepaid) to be
held as security for the obligations of Borrower hereunder pursuant to a cash
collateral agreement to be entered into in form and substance satisfactory to
Agent, with such cash collateral to be directly applied upon the first
occurrence (or occurrences) thereafter of the last day of an Interest Period
applicable to the Affected Libor Accounts (or such earlier date or dates as
shall be requested by Borrower), to repay an aggregate principal amount of such
Term Loans equal to the Affected Libor Accounts not initially repaid pursuant to
this sentence.

     Section 6.6   Taxes.

          (a)  Withholding Taxes. Except as otherwise provided in this
     Agreement, any and all payments by any Loan Party to or for the account of
     any Lender, Agent, Arranger, or the Issuing Bank hereunder or under any
     other Loan Document shall be made free and clear of and without deduction
     for any and all present or future taxes, duties, levies, imposts,
     deductions, charges, or withholdings, and all liabilities with respect
     thereto, excluding, in the case of each Lender, Agent, Arranger, or the
     Issuing Bank (as applicable), taxes imposed on or measured by its income,
     and franchise taxes imposed on it, by the jurisdiction under the laws of
     which such Lender (or its Applicable Lending Office), Agent, Arranger, or
     the Issuing Bank (as the case may be) is organized, located, or doing
     business or any political subdivision thereof (all such non-excluded taxes,
     duties, levies, imposts, deductions, charges, withholdings, and liabilities
     being hereinafter referred to as "Taxes"). If a Loan Party shall be
     required by law to deduct any Taxes from or in respect of any sum payable
     under any Loan Document to any Lender, Agent, Arranger, or the Issuing Bank
     (as applicable), (i) the



CREDIT AGREEMENT - Page 41

<PAGE>   48


     sum payable shall be increased as necessary so that after making all
     required deductions (including, without limitation, deductions applicable
     to additional sums payable under this Section 6.6) such Lender, Agent,
     Arranger, or the Issuing Bank (as applicable) receives an amount equal to
     the sum it would have received had no such deductions been made, (ii) the
     applicable Loan Party shall make such deductions, (iii) the applicable Loan
     Party shall pay the full amount deducted to the relevant taxing authority
     or other authority in accordance with applicable law, and (iv) the
     applicable Loan Party shall furnish to Agent the original or a certified
     copy of a receipt evidencing payment thereof.

          (b)  Stamp Taxes, Etc. In addition, Borrower agrees to pay any and all
     present or future stamp or documentary taxes and any other excise or
     property taxes or charges or similar levies which arise from any payment
     made under this Agreement or any other Loan Document or from the execution
     or delivery of, or otherwise with respect to, this Agreement or any other
     Loan Document ("Other Taxes").

          (c)  Tax Indemnification. BORROWER AGREES TO INDEMNIFY EACH LENDER,
     THE AGENT-RELATED PERSONS, AND THE ISSUING BANK FOR THE FULL AMOUNT OF
     TAXES AND OTHER TAXES (INCLUDING, WITHOUT LIMITATION, ANY TAXES OR OTHER
     TAXES IMPOSED OR ASSERTED BY ANY JURISDICTION ON AMOUNTS PAYABLE UNDER THIS
     SECTION 6.6) PAID BY SUCH LENDER, ANY AGENT-RELATED PERSON, OR THE ISSUING
     BANK (AS THE CASE MAY BE) AND ANY LIABILITY (INCLUDING, WITHOUT LIMITATION,
     PENALTIES, INTEREST, AND EXPENSES) ARISING THEREFROM OR WITH RESPECT
     THERETO, OTHER THAN PENALTIES, ADDITIONS TO TAX, INTEREST, AND EXPENSES
     ARISING AS A RESULT OF GROSS NEGLIGENCE OR WILLFUL MISCONDUCT ON THE PART
     OF SUCH LENDER OR AGENT-RELATED PERSON.

          (d)  Mitigation. If Borrower is required to pay additional amounts to
     or for the account of any Lender pursuant to this Article 6, then such
     Lender agrees to use commercially reasonable efforts (consistent with its
     internal policy and legal and regulatory restrictions) to change the
     jurisdiction of its Applicable Lending Office so as to eliminate or reduce
     any such additional payment which may thereafter accrue if such change, in
     the reasonable judgment of such Lender, is not otherwise disadvantageous to
     such Lender. To the extent Borrower pays sums pursuant to this Section 6.6
     and the applicable Lender, Agent, Arranger, or the Issuing Bank receives a
     refund of any or all of such sums, such refund shall be applied to reduce
     any amounts then due and owing under this Agreement or, to the extent that
     no amounts are due and owing under this Agreement at the time such refund
     is received, the party receiving such refund shall pay over such refunded
     sums to Borrower, provided that no Default is in existence at such time.

     Section 6.7   Withholding Tax Exemption. Each Lender organized under the
laws of a jurisdiction outside the U.S., on or prior to the date of its
execution and delivery of this Agreement in the case of each Lender listed on
the signature pages hereof and on or prior to the date on which it becomes a
Lender in the case of each other Lender, and from time to time thereafter if
requested in writing by Borrower or Agent (but only so long as such Lender
remains lawfully able to do so),



CREDIT AGREEMENT - Page 42

<PAGE>   49


shall provide Borrower and Agent with (a) if such Lender is a "bank" within the
meaning of Section 881(c)(3)(A) of the Code, (i) Internal Revenue Service Form
1001 or 4224, as appropriate, or any successor form prescribed by the Internal
Revenue Service, certifying that such Lender is entitled to benefits under an
income tax treaty to which the U.S. is a party which reduces to zero the rate of
withholding tax on payments of interest or certifying that the income receivable
pursuant to this Agreement is effectively connected with the conduct of a trade
or business in the U.S., (ii) Internal Revenue Service Form W-8 or W-9, as
appropriate, or any successor form prescribed by the Internal Revenue Service,
and (iii) any other form or certificate required by any taxing authority
(including, without limitation, any certificate required by Sections 871(h) and
881(c) of the Code), certifying that such Lender is entitled to a complete
exemption from tax on payments pursuant to any of the Loan Documents or (b) if
such Lender is not a "bank" within the meaning of Section 881(c)(3)(A) of the
Code, a Form W-8, or any subsequent versions thereof or successors thereto (and,
if such non-U.S. Lender delivers a Form W-8, a certificate (including, without
limitation, any certificate required by Sections 871(h) and 881(c) of the Code)
representing that such non-U.S. Lender is not a bank for purposes of Section
881(c) of the Code, is not a 10-percent shareholder (within the meaning of
Section 871(h)(3)(B) of the Code) of Borrower and is not a controlled foreign
corporation related to Borrower (within the meaning of Section 864(d)(4) of the
Code)), properly completed and duly executed by such non-U.S. Lender claiming
complete exemption from United States Federal withholding tax on payments of
interest by Borrower under this Agreement and the other Loan Documents. For any
period with respect to which a Lender has failed to provide Borrower and Agent
with the appropriate form pursuant to this Section and thereby to establish
complete exemption from U.S. withholding tax (unless such failure to establish
complete exemption from U.S. withholding tax is due to a change in treaty, law,
or regulation occurring subsequent to the date on which a form originally was
required to be provided), (A) the applicable Loan Party shall deduct all
required Taxes from any amounts payable to such Lender under any Loan Document,
(B) the applicable Loan Party shall pay the full amount allocated to the
relevant taxing authority or other authority in accordance with applicable law,
(C) the applicable Loan Party shall furnish to Agent the original or a certified
copy of a receipt evidencing payment thereof, and (D) such Lender shall not be
entitled to an indemnification or increases in the sum payable under Section 6.6
or Section 15.7 with respect to Taxes imposed by the U.S.; provided, however,
that should a Lender, which is otherwise exempt from or subject to a reduced
rate of withholding tax, become subject to Taxes because of its failure to
deliver a form required hereunder, Borrower shall take such steps as such Lender
shall reasonably request to assist such Lender to recover such Taxes.

     Section 6.8   Replacement of Lenders. If at any time a Lender becomes a
Gross Up Lender (as identified below), Borrower shall have the right to replace
such Lender with another Person; provided that (a) such new Person shall be an
Eligible Assignee and such new Person shall execute an Assignment and
Acceptance, (b) neither Agent nor any Lender shall have any obligation to
Borrower to find such other Person, (c) in the event of a replacement of a Gross
Up Lender, in order for Borrower to be entitled to replace such Lender, such
replacement must take place no later than ninety (90) days after the date the
Gross Up Lender shall notify Borrower and Agent of its desire to be paid any
sums pursuant to this Article 6, and (d) if Borrower replaces one Gross Up
Lender, it must replace all Gross Up Lenders or replace all Gross Up Lenders on
a pro rata basis. Each Lender agrees to its replacement at the option of
Borrower pursuant to this Section 6.8 and in accordance with Section 16.8;
provided that the successor Lender shall purchase without recourse such Lender's



CREDIT AGREEMENT - Page 43

<PAGE>   50

interest in the Obligations of Borrower to such Lender for cash in an aggregate
amount equal to the aggregate unpaid principal thereof, all unpaid interest
accrued thereon, all unpaid commitment fees accrued for the account of such
Lender hereunder or under any other Loan Document, and Borrower shall pay to the
Gross Up Lender any breakage costs incurred by the selling Lender because of the
prepayment of any Libor Accounts, all other fees (if any) applicable thereto,
and all other amounts (including, without limitation, any amounts under this
Article 6) then owing to such Lender hereunder or under any other Loan Document
and the Loan Parties shall execute a release addressed to such Lender releasing
such Lender from all claims arising in connection with the Loan Documents. Any
Lender who requests a payment pursuant to this Article 6 shall be deemed a
"Gross Up Lender".


                                    ARTICLE 7

                                    Security

     Section 7.1   Collateral. To secure the full and complete payment and
performance of the Obligations, Parent and Borrower shall, and shall cause each
of the Guarantors to, grant to Agent, for the benefit of Agent and the Lenders,
a perfected, first priority Lien (subject only to any Lien permitted under
Section 11.2 to the extent, if any, any such Lien would have a higher priority
by operation of law than the Liens in favor of Agent) on all of its right,
title, and interest in and to the following Property, whether now owned or
hereafter acquired, pursuant to the Security Documents:

          (a)  all Capital Stock of each Domestic Subsidiary (whether present or
     future, but (i) excluding the Capital Stock of InterVoice Communications
     International, Inc., Phone Star Corp., and VoicePlex Corporation, each of
     which are Wholly-Owned Domestic Subsidiaries and which Parent agrees to
     dissolve in accordance with applicable law within sixty (60) days of the
     Closing Date and (ii) to the extent required by the agreement of limited
     partnership of InterVoice Limited Partnership, excluding 25% of the
     partnership interest of such limited partnership), including, without
     limitation, the Shares owned by Parent or Borrower at any time, owned as of
     the Closing Date or thereafter acquired by Parent or any Subsidiary of
     Parent;

          (b)  the lesser of (i) 65% of the shares of each class of Capital

     and any Foreign Subsidiary, except as provided in Section 7.6) to Guarantee
     the payment and performance of the Obligations by executing and delivering
     to Agent an appropriate Guaranty; and

          (c)  cause each such Subsidiary (excluding any Immaterial Subsidiary
     and any Foreign Subsidiary, except as provided in Section 7.6) to execute
     and deliver to Agent an appropriate Security Agreement and such other
     Security Documents as Agent may request to grant Agent, for the benefit of
     Agent and the Lenders, a perfected, first priority Lien (except for

other appropriate Persons (as applicable) to, grant or cause to be granted to

in the case of any Foreign Subsidiaries directly owned by Parent or a Domestic
Subsidiary to an aggregate amount of sixty-five percent (65%) of the Capital
Stock of each such Foreign Subsidiary or, if an Event of Default exists, as
provided in Section 7.6, (y) in the case of Foreign Subsidiaries, other than
Foreign Subsidiaries directly owned by Parent or a Domestic Subsidiary, if an
Event of Default exists, as provided in Section 7.6). Each of Parent and
Borrower covenants that none of the Capital Stock to be pledged in accordance
with this Section 7.3 shall be subject to any transfer restriction,
shareholders' agreement, or other restriction except for such restrictions under
applicable securities laws and such restrictions, if any, as may be acceptable

shall be obligated to pledge more than 65% of each class of the issued and
outstanding Capital Stock of any Foreign Subsidiary that is a direct,

Foreign Subsidiary shall be obligated to execute a Guaranty guaranteeing payment
or performance of the Obligations, and (iii) no Foreign Subsidiary shall be
obligated to execute a Security Agreement or any other Security Document
securing payment or performance of the Obligations. In connection with and in

without limitation, stock certificates, stock powers, and financing statements)
as Agent may request in order for it to obtain and maintain the perfected, first
priority Liens to be granted in accordance with this Section 7.3.

Subsidiaries, contemporaneously with the acquisition of any fee real Property
to, execute, acknowledge, and deliver to Agent, for the benefit of Agent and the
Lenders, a Mortgage or an amendment or modification to a then existing Mortgage
covering all fee real Property acquired by such Loan Party subsequent to the
Closing Date, together with evidence satisfactory to Agent and its counsel,
including, without limitation, if requested by Agent, a commitment for a
mortgagee's policy of title insurance or a title opinion in favor of Agent, in
form and substance satisfactory to Agent, that the Mortgage creates a valid,
first priority Lien on the fee estate in favor of Agent, for the benefit of
Agent and the Lenders (except for Permitted Liens, if any), together with
appraisals and surveys if requested by Agent. Following the date of each such
acquisition of Property, if requested by Agent, Parent shall, and shall cause
each of its other Subsidiaries (other than Foreign Subsidiaries) with an
interest in such Properties to, (a) deliver or cause to be delivered to Agent, a
mortgagee's policy of title insurance insuring the Liens of the Mortgage
covering such fee real Property in an amount satisfactory to Agent on standard
form policies (except for Permitted Liens, if any) and (b) provide Agent with a
current environmental assessment of such Property in form and substance
satisfactory to Agent.

upon five (5) Business Days prior written request by Borrower, Agent shall
execute at Borrower's expense such documents as may be



CREDIT AGREEMENT - Page 46

<PAGE>   53


necessary to evidence the release by Agent of its Liens on such Collateral being
sold, transferred, or otherwise disposed of; provided, however, that (a) Agent
shall not be required to release any Lien on any Collateral if a Default is in
existence, (b) Agent shall not be required to execute any such document on terms
which, in Agent's opinion, would expose Agent to liability or create any
obligation not reimbursed by Borrower or entail any consequences other than the
release of such Lien without recourse or warranty, and (c) such release shall
not in any manner discharge, affect, or impair any of the Obligations or any of
Agent's Liens on any Collateral retained by any Loan Party, including, without
limitation, its Liens on the proceeds of any such sale, transfer, or other
disposition.

     Section 7.6   Collateral and Guaranties of Foreign Subsidiaries and
Immaterial Subsidiaries. Parent agrees that, notwithstanding anything to the
contrary contained in this Article 7 or elsewhere in this Agreement or in any

Days after) any written request therefor made by Agent or the Required Lenders
after and during the continuation of an Event of Default pursuant to Sections
13.1(a), (e), (f), and (i), and Section 13.1(c) with respect to failure to
comply with Article 12 Parent will, and will cause each of its Subsidiaries to,

     Subsidiary (whether present or future and whether direct or indirect) which

     without limitation, stock certificates, stock powers, financing statements,
     and other Security Documents) as Agent may request in connection with any

     may be unable to recognize and perform properly date- sensitive functions
     involving certain dates prior to and any date after December 31, 1999),
     (ii) developed a detailed plan and timeline for addressing the Year 2000
     Problem on a timely basis, and (iii) to date, implemented that plan in
     accordance with that timetable in all material respects. Parent and its
     Subsidiaries anticipate that all computer applications that are material to
     their respective businesses and operations will on a timely basis be able
     to perform properly date-sensitive functions for all dates before and after
     January 1, 2000 (that is, be "Year 2000 Compliant") except where any such
     non-performance could not reasonably be expected to have a Material Adverse
     Effect.

          (b)  Each of Parent and its Subsidiaries has made inquiry of its key
     suppliers, vendors, and customers as to whether such Persons will on a

     believes that all such Persons will be so compliant except where
     non-compliance could not reasonably be expected to result in a Material
     Adverse Effect. For purposes hereof, "key suppliers, vendors, and
     customers" refers to those suppliers, vendors, and customers of Parent or a
     Subsidiary of Parent the business failure of which would with reasonable
     probability be expected to have a Material Adverse Effect.

     selected by the applicable Person and having an A.M. Best Rating of "A-" or
     better and being in a financial size category of "VI" or larger, or by
     other companies reasonably acceptable to Agent. Each policy referred to in

     insured, as applicable, provide that it will not be canceled, amended, or
     reduced except after not less than thirty (30) days' prior written notice

     such Subsidiary) payable by any insurance company to be deposited promptly
     with Agent as security for the Obligations if a Default has then occurred
     and is continuing.

          (c)  If a Default shall have occurred and be continuing, Parent will,
     and will cause each Subsidiary of Parent, to cause all proceeds of

          (i)  Any Loan Party shall fail to pay when due any principal of or
     interest on any Debt (other than the Obligations) beyond the period of

     Section 13.2  Remedies. If any Event of Default shall occur and be
continuing, Agent may (and if directed by the Required Lenders, shall) do any
one or more of the following:

          (a)  Acceleration. By notice to Borrower, declare all outstanding
     principal of and accrued and unpaid interest on the Notes and all other
     amounts payable by Borrower under the Loan Documents immediately due and
     payable, and the same shall thereupon become immediately due and payable,
     without further notice, demand, presentment, notice of dishonor, notice of
     acceleration, notice of intent to accelerate, protest, or other formalities
     of any kind, all of which are hereby expressly waived by Borrower except as
     where required by the specific terms of this Agreement or the other Loan
     Documents;

          (b)  Termination of Commitments. Terminate the Commitments, including,
     without limitation, the obligation of the Issuing Bank to issue Letters of
     Credit, without notice to Borrower or any other Person;

          (c)  Judgment. Reduce any claim to judgment;

          (d)  Foreclosure. Foreclose or otherwise enforce any Lien granted to
     Agent, for the benefit of Agent and the Lenders to secure payment and
     performance of the Obligations in accordance with the terms of the Loan
     Documents; and

          (e)  Rights. Exercise any and all rights and remedies afforded by the
     laws of the State of Texas, or any other jurisdiction governing any of the
     Loan Documents, by equity, or otherwise;

provided, however, that, upon the occurrence of an Event of Default under
Section 13.1(e) or Section 13.1(f), the Commitments of all of the Lenders, and
the obligation of the Issuing Bank to issue Letters of Credit, shall
automatically terminate and the outstanding principal of and accrued and unpaid
interest on the Notes and all other amounts payable by Borrower or any other
Loan Party under the Loan Documents shall thereupon become immediately due and
payable without notice, demand, presentment, notice of dishonor, notice of
acceleration, notice of intent to accelerate, protest, or other formalities of
any kind, all of which are hereby expressly waived by Parent and Borrower.



CREDIT AGREEMENT - Page 77

<PAGE>   84


     Section 13.3  Cash Collateral. If an Event of Default shall have occurred
and be continuing, Parent and/or Borrower shall, if requested by Agent or the
Required Lenders, pledge to Agent as security for the Obligations, pursuant to
agreements in form and substance satisfactory to Agent, an amount in immediately
available funds equal to the then outstanding Letter of Credit Liabilities, such
funds to be held in a cash collateral account by Agent without any right of
withdrawal by Parent or Borrower. If such Event of Default is subsequently
cured, then the balance of such cash collateral account shall be released to
Parent and/or Borrower, as applicable.

     Section 13.4  Performance by Agent. Upon the occurrence of a Default, if
any Loan Party shall fail to perform any agreement in accordance with the terms
of the Loan Documents, Agent may, at the direction of the Required Lenders,
perform or attempt to perform such agreement on behalf of such Loan Party. In
such event, Parent and/or Borrower shall, at the request of Agent, promptly pay
any amount expended by Agent or the Lenders in connection with such performance
or attempted performance, to Agent at the Principal Office together with
interest thereon at the Default Rate applicable to Base Rate Accounts from and
including the date of such expenditure to but excluding the date such
expenditure is paid in full. Notwithstanding the foregoing, it is expressly
agreed that neither Agent, Arranger, nor any Lender shall have any liability or
responsibility for the performance of any obligation of any Loan Party under any
Loan Document.

     Section 13.5  Set-off. If an Event of Default shall have occurred and be
continuing, each Lender is hereby authorized at any time and from time to time,
without notice to Parent, Borrower, or any other Person (any such notice being
hereby expressly waived), to set-off and apply any and all deposits (general or
special, time or demand, provisional or final) at any time held and other
indebtedness at any time owing by such Lender to or for the credit or the
account of Parent, Borrower, or any other Loan Party against any and all of the
Obligations now or hereafter existing under any Loan Document, irrespective of
whether or not Agent or such Lender shall have made any demand under such Loan
Documents and although the Obligations may be unmatured. Each Lender agrees
promptly to notify Parent and Borrower (with a copy to Agent) after any such
set-off and application, provided that the failure to give such notice shall not
affect the validity of such set-off and application. The rights and remedies of
each Lender hereunder are in addition to other rights and remedies (including,
without limitation, other rights of set-off) which such Lender may have.

     Section 13.6  Continuance of Default. For purposes of all Loan Documents, a
Default shall be deemed to have continued and exist until Agent shall have
actually received evidence satisfactory to Agent that such Default shall have
been remedied.


                                   ARTICLE 14

                               Guaranty of Parent

     Section 14.1  Guaranty. Parent hereby irrevocably and unconditionally
Guarantees to Agent, for the benefit of Agent and the Lenders, the full and
prompt payment and performance of the Guaranteed Indebtedness (as defined below)
upon the terms set forth in this Article 14. As used in this Article 14, the
term "Guaranteed Indebtedness" means all of the Obligations, and shall include,
without limitation, any and all post-petition interest and expenses (including,
without



CREDIT AGREEMENT - Page 78

<PAGE>   85


limitation, attorneys' fees) whether or not allowed under any bankruptcy,
insolvency, or other similar law and all reasonable attorneys' fees and all
other costs and expenses incurred by Agent and the Lenders in connection with
the administration, enforcement, or collection of the Obligations pursuant to
this Article 14.

     Section 14.2  Contribution. Parent, together with each other Guarantor
under any Guaranty, if any, relating to this Credit Agreement (the "Related
Guaranties") which contain a contribution provision similar to that set forth in
this Section, agrees that it and all such other Guarantors (collectively, the
"Contributing Guarantors") together desire to allocate among themselves, in a
fair and equitable manner, their obligations arising under this Agreement and
the Related Guaranties. Accordingly, in the event any payment or distribution is
made by Parent under this Agreement or a Guarantor under a Related Guaranty (a
"Funding Guarantor") that exceeds its Fair Share (as defined below), that
Funding Guarantor shall be entitled to a contribution from each of the other
Contributing Guarantors in the amount of such other Contributing Guarantor's
Fair Share Shortfall (as defined below), with the result that all such
contributions will cause each Contributing Guarantor's Aggregate Payments (as
defined below) to equal its Fair Share; provided, however, that the obligations
to or from any Funding Guarantor as described in this Section shall be
subordinate to the obligation of Parent to pay the Guaranteed Indebtedness as
more fully set forth in Section 14.1. "Fair Share" means, with respect to a
Contributing Guarantor as of any date of determination, an amount equal to (a)
the ratio of (i) the Adjusted Maximum Amount (as defined below) with respect to
such Contributing Guarantor to (ii) the aggregate of the Adjusted Maximum
Amounts with respect to all Contributing Guarantors, multiplied by (b) the
aggregate amount paid or distributed on or before such date by all Funding
Guarantors under this Agreement and the Related Guaranties in respect of the
obligations Guaranteed. "Fair Share Shortfall" means, with respect to a
Contributing Guarantor as of any date of determination, the excess, if any, of
the Fair Share of such Contributing Guarantor over the Aggregate Payments of
such Contributing Guarantor. "Adjusted Maximum Amount" means, with respect to a
Contributing Guarantor as of any date of determination, the maximum aggregate
amount of the obligations of such Contributing Guarantor under this Agreement or
a Related Guaranty, in each case determined in accordance with the provisions
hereof and thereof; provided that, solely for purposes of calculating the
"Adjusted Maximum Amount" with respect to any Contributing Guarantor for
purposes of this Section, the assets or liabilities arising by virtue of any
rights to or obligations of contribution hereunder or under any similar
provision contained in a Related Guaranty shall not be considered as assets or
liabilities of such Contributing Guarantor. "Aggregate Payments" means, with
respect to a Contributing Guarantor as of any date of determination, the
aggregate amount of all payments and distributions made on or before such date
by such Contributing Guarantor in respect of this Agreement and the Related
Guaranties (including, without limitation, in respect of this Section or any
similar provision contained in a Related Guaranty). The amounts payable as
contributions hereunder and under similar provisions in the Related Guaranties
shall be determined as of the date on which the related payment or distribution
is made by the applicable Funding Guarantor. The allocation among Contributing
Guarantors of their obligations as set forth in this Section or any similar
provision contained in a Related Guaranty shall not be construed in any way to
limit the liability of any Contributing Guarantor hereunder or under a Related
Guaranty. Each Contributing Guarantor under a Related Guaranty is a third party
beneficiary to the contribution agreement set forth in this Section.

     Section 14.3  Guaranty of Performance. The Guaranty provided for in this
Article 14 shall be an absolute, continuing, irrevocable, and unconditional
guaranty of payment and performance, and not a guaranty of collection, and
Parent shall remain liable on its obligations hereunder until the payment and
performance in full of the Guaranteed Indebtedness. No set-off, counterclaim,
recoupment, reduction, or diminution of any obligation, or any defense of any
kind or nature (other than payment or performance) which Borrower may have
against Agent, any Lender, the Issuing Bank, or any other party, or which Parent
may have against Borrower, Agent, any Lender, the Issuing Bank, or any other
party, shall be available to, or shall be asserted by, Parent against Agent, any
Lender, or any subsequent holder of the Guaranteed Indebtedness or any part
thereof or against payment of the Guaranteed Indebtedness or any part thereof.

     Section 14.4  Rights Cumulative. If Parent becomes liable for any
indebtedness owing by Borrower to Agent or any Lender by endorsement or
otherwise, other than pursuant to the terms of this Article 14, such liability
shall not be in any manner impaired or affected thereby, and the rights of Agent
and the Lenders hereunder shall be cumulative of any and all other rights that
Agent and the Lenders may ever have against Parent. The exercise by Agent and
the Lenders of any right or remedy under this Article 14 or under any other
instrument, or at law or in equity, shall not preclude the concurrent or
subsequent exercise of any other right or remedy.

     Section 14.5  Payment Upon Event of Default; Subrogation. Upon the
occurrence of an Event of Default, whether for payment of any portion of the
Guaranteed Indebtedness or any other performance of the terms of this Agreement,
or otherwise when any portion of the Guaranteed Indebtedness becomes due,
whether by its terms, by acceleration, or otherwise, Parent shall promptly pay
the amount due thereon to Agent, for the benefit of Agent and the Lenders,
without notice or demand in lawful currency of the U.S., and it shall not be
necessary for Agent or any Lender, in order to enforce such payment by Parent,
first to institute suit or exhaust its remedies against Borrower or others
liable on such Guaranteed Indebtedness, or to enforce any rights against any
Collateral which shall ever have been given to secure such Guaranteed
Indebtedness. In the event such payment is made by Parent, then Parent shall be
subrogated to the rights then held by Agent and the Lenders with respect to the
Guaranteed Indebtedness to the extent to which the Guaranteed Indebtedness was
discharged by Parent and, in addition, upon payment by Parent of any sums to
Agent hereunder, all rights of Parent against Borrower, any other Guarantor or
any Collateral arising as a result therefrom by way of right of subrogation,
reimbursement, or otherwise shall in all respects be subordinate and junior in
right of payment to the prior indefeasible payment in full of the Guaranteed
Indebtedness and no such right or remedy of subrogation, reimbursement or
otherwise shall be exercised or otherwise entered unless and until the
Guaranteed Indebtedness has been indefeasibly paid in full.

     Section 14.6  No Effect of Stay in Bankruptcy. If acceleration of the time
for payment of any amount payable by Borrower under the Guaranteed Indebtedness
is stayed upon the insolvency, bankruptcy, or reorganization of Borrower, all
such amounts otherwise subject to acceleration under the terms of the Guaranteed
Indebtedness shall nonetheless be payable by Parent hereunder forthwith on
demand by Agent or any Lender.

     Section 14.7  Nonimpairment of Guaranty. Parent hereby agrees that its
obligations under this Article 14 shall not be released, discharged, diminished,
impaired, reduced, or affected for any



CREDIT AGREEMENT - Page 80

<PAGE>   87


reason or by the occurrence of any event, including, without limitation, one or
more of the following occurrences or events, whether or not with notice to or
the consent of Parent: (a) the taking or accepting of collateral as security for
any or all of the Guaranteed Indebtedness or the release, surrender, exchange,
or subordination of any collateral now or hereafter securing any or all of the
Guaranteed Indebtedness; (b) any partial release of the liability of Parent
hereunder, or the full or partial release of any other Guarantor of the
Guaranteed Indebtedness from liability for any or all of the Guaranteed
Indebtedness; (c) any disability of Borrower, or the dissolution, insolvency, or
bankruptcy of Borrower, Parent, or any other party at any time liable for the
payment of any or all of the Guaranteed Indebtedness; (d) any renewal,
extension, modification, waiver, amendment, or rearrangement of any or all of
the Guaranteed Indebtedness or any instrument, document, or agreement
evidencing, securing, or otherwise relating to any or all of the Guaranteed
Indebtedness; (e) any adjustment, indulgence, forbearance, waiver, or compromise
that may be granted or given by Agent or any Lender to Borrower, Parent, or any
other party ever liable for any or all of the Guaranteed Indebtedness; (f) any
neglect, delay, omission, failure, or refusal of Agent or any Lender to take or
prosecute any action for the collection of any of the Guaranteed Indebtedness or
to foreclose or take or prosecute any action in connection with any instrument,
document, or agreement evidencing, securing, or otherwise relating to any or all
of the Guaranteed Indebtedness; (g) the unenforceability or invalidity of any or
all of the Guaranteed Indebtedness or of any instrument, document, or agreement
evidencing, securing, or otherwise relating to any or all of the Guaranteed
Indebtedness; (h) any payment by Borrower or any other party to Agent or any
Lender is held to constitute a preference under applicable bankruptcy or
insolvency law or if for any other reason Agent or any Lender is required to
refund any payment or pay the amount thereof to someone else; (i) the settlement
or compromise of any of the Guaranteed Indebtedness; (j) the non-perfection of
any Lien securing any or all of the Guaranteed Indebtedness; (k) any impairment
of any Collateral securing any or all of the Guaranteed Indebtedness; (l) the
failure of Agent or any Lender to sell any Collateral securing any or all of the
Guaranteed Indebtedness in a commercially reasonable manner or as otherwise
required by law; (m) any change in the corporate existence, structure, or
ownership of Borrower; or (n) any other circumstance which might otherwise
constitute a defense available to, or discharge of, Borrower, Parent, or any
other party at any time liable for the payment of any or all of the Guaranteed
Indebtedness other than payment of the Guaranteed Indebtedness.

     Section 14.8  Additional representations and Warranties. In addition to the
representations and warranties contained in Article 9 of this Agreement, Parent
represents and warrants as follows:

          (a)  Borrower is a wholly-owned direct Subsidiary of Parent. The value
     of the consideration received and to be received by Parent as a result of
     Parent, Borrower, Agent, and the Lenders entering into this Agreement and
     Parent's executing and delivering this Agreement and Parent's liability
     under this Article 14 and the other Loan Documents to which it is a party
     is reasonably worth at least as much as the liability and obligation of
     Parent hereunder and thereunder, and this Agreement and such liability and
     obligation of Parent have benefitted and may reasonably be expected to
     benefit Parent directly or indirectly. Execution and delivery of this
     Agreement and the other Loan Documents to which Parent is a party is
     necessary or convenient to the conduct, promotion, and attainment of the
     business of Parent.



CREDIT AGREEMENT - Page 81

<PAGE>   88


          (b)  Parent has, independently and without reliance upon Agent or any
     Lender and based upon such documents and information as Parent has deemed
     appropriate, made its own analysis and decision to enter into the Loan
     Documents to which it is a party.

          (c)  Parent has adequate means to obtain from Borrower on a continuing
     basis information concerning the financial condition and assets of
     Borrower, and Parent is not relying upon Agent, the Lenders, or the Issuing
     Bank to provide (and neither Agent, any Lender, nor the Issuing Bank shall
     have any duty to provide) any such information to Parent either now or in
     the future.

     Section 14.9  Subordination.

          (a)  Parent hereby agrees that the Subordinated Indebtedness (as
     defined below) shall be subordinate and junior in right of payment to the
     prior indefeasible payment in full of all Guaranteed Indebtedness as herein
     provided. The Subordinated Indebtedness shall not be payable, and no
     payment of principal, interest, or other amounts on account thereof, and no
     property or Guarantee of any nature to secure or pay the Subordinated
     Indebtedness or any part thereof shall be made or given, directly or
     indirectly by or on behalf of any Debtor (as defined below) or received,
     accepted, retained, or applied by Guarantor unless and until the Guaranteed
     Indebtedness shall have been indefeasibly paid in full in cash; except that
     prior to the occurrence of an Event of Default, Parent shall have the right
     to receive payments on the Subordinated Indebtedness made in the ordinary
     course of business unless, and except to the extent that, the payment or
     receipt of such payments is prohibited or otherwise restricted by this
     Agreement or another Loan Document. During the existence of a Default, no
     payments of principal or interest may be made or given, directly or
     indirectly, by or on behalf of any Debtor or received, accepted, retained,
     or applied by Parent unless and until the Guaranteed Indebtedness shall
     have been indefeasibly paid in full in cash. If any sums shall be paid to
     Parent by any Debtor or any other Person on account of the Subordinated
     Indebtedness when such payment is not permitted hereunder, such sums shall
     be held in trust by Parent for the benefit of Agent (for the benefit of
     Agent and the Lenders) and shall forthwith be paid to Agent without
     affecting the liability of Parent under this Article 14 and may be applied
     by Agent against the Guaranteed Indebtedness in accordance with the terms
     of the Credit Agreement. Upon the request of Agent, Parent shall execute,
     deliver, and endorse to Agent such documentation as Agent may request to
     perfect, preserve, and enforce its rights hereunder. For purposes of this
     Section 14.9, the term "Subordinated Indebtedness" means all indebtedness,
     liabilities, and obligations of Borrower or any other party obligated at
     any time to pay any of the Guaranteed Indebtedness other than Parent
     (Borrower and such other obligated parties (including, without limitation,
     any Contributing Guarantors) are referred to herein as the "Debtors") to
     Parent, whether such indebtedness, liabilities, and obligations now exist
     or are hereafter incurred or arise, or are direct, indirect, contingent,
     primary, secondary, several, joint and several, or otherwise, and
     irrespective of whether such indebtedness, liabilities, or obligations are
     evidenced by a note, contract, open account, or otherwise, and irrespective
     of the Person or Persons in whose favor such indebtedness, obligations, or
     liabilities may, at their inception, have been, or may hereafter be
     created, or the manner in which they have been or may hereafter be acquired
     by Parent.



CREDIT AGREEMENT - Page 82

<PAGE>   89


          (b)  Parent agrees that any and all Liens (including, without
     limitation, any judgment liens), upon any Debtor's assets securing payment
     of any Subordinated Indebtedness shall be and remain inferior and
     subordinate to any and all Liens upon any Debtor's assets securing payment
     of the Guaranteed Indebtedness, or any part thereof, regardless of whether
     such Liens in favor of Parent, Agent, or any Lender presently exist or are
     hereafter created or attached. Without the prior written consent of Agent,
     until final repayment in full of all Guaranteed Indebtedness, Parent shall
     not (i) file suit against any Debtor or exercise or enforce any other
     creditor's right it may have against any Debtor, or (ii) foreclose,
     repossess, sequester, or otherwise take steps or institute any action or
     proceedings (judicial or otherwise, including, without limitation, the
     commencement of, or joinder in, any liquidation, bankruptcy, rearrangement,
     debtor's relief, or insolvency proceeding) to enforce any obligations of
     any Debtor to Parent or any Liens held by Parent on assets of any Debtor.

          (c)  In the event of any receivership, bankruptcy, reorganization,
     rearrangement, debtor's relief, or other insolvency proceeding involving
     any Debtor as debtor, Agent shall have the right to prove and vote any
     claim under the Subordinated Indebtedness and to receive directly from the
     receiver, trustee, or other court custodian all dividends, distributions,
     and payments made in respect of the Subordinated Indebtedness until the
     Guaranteed Indebtedness has been indefeasibly paid in full in cash. Agent
     may apply any such dividends, distributions, and payments against the
     Guaranteed Indebtedness in accordance with the terms of this Agreement.

          (d)  Parent agrees that all promissory notes, accounts receivable,
     ledgers, records, or any other evidence of Subordinated Indebtedness shall
     contain a specific written notice thereon that the indebtedness evidenced
     thereby is subordinated under the terms of this Article 14.

     Section 14.10 Tolling of Limitations. Any acknowledgment or new promise,
whether by payment of principal or interest or otherwise and whether by Borrower
or others (including, without limitation, any other Guarantor), with respect to
any of the Guaranteed Indebtedness shall, if the statute of limitations in favor
of Parent against Agent or any Lender shall have commenced to run, toll the
running of such statute of limitations and, if the period of such statute of
limitations shall have expired, prevent the operation of such statute of
limitations.

     Section 14.11 Waivers. Parent hereby waives promptness, diligence, notice
of any default under the Guaranteed Indebtedness, demand of payment, notice of
acceptance of the Guaranty contained in this Article 14, presentment, notice of
protest, notice of dishonor, notice of the incurring by Borrower of additional
indebtedness, and all other notices and demands with respect to the Guaranteed
Indebtedness and this Agreement.

                                   ARTICLE 15

                                      Agent

     Section 15.1  Appointment and Authorization; "Agent".

          (a)  Each Lender hereby irrevocably (subject to Section 15.9)
     appoints, designates, and authorizes Agent to take such action on its
     behalf under the provisions of this Agreement and each other Loan Document
     and to exercise such powers and perform such duties as are expressly
     delegated to it by the terms of this Agreement or any other Loan Document,
     together with such powers as are reasonably incidental thereto.
     Notwithstanding any provision to the contrary contained elsewhere in this
     Agreement or in any other Loan Document, Agent shall not have any duties or
     responsibilities, except those expressly set forth herein, nor shall Agent
     have or be deemed to have any fiduciary relationship with any Lender, and
     no implied covenants, functions, responsibilities, duties, obligations, or
     liabilities shall be read into this Agreement or any other Loan Document or
     otherwise exist against Agent. Without limiting the generality of the
     foregoing sentence, the use of the term "agent" in this Agreement with
     reference to Agent is not intended to connote any fiduciary or other
     implied (or express) obligations arising under agency doctrine of any
     applicable law. Instead, such term is used merely as a matter of market
     custom, and is intended to create or reflect only an administrative
     relationship between independent contracting parties.

          (b)  The Issuing Bank shall act on behalf of the Lenders with respect
     to any Letters of Credit issued by the Issuing Bank and the documents
     associated therewith until such time and except for so long as Agent may
     agree at the request of the Required Lenders to act for such Issuing Bank
     with respect thereto; provided, however, that the Issuing Bank shall have
     all of the benefits and immunities (i) provided to Agent in this Article 15
     with respect to any acts taken or omissions suffered by the Issuing Bank in
     connection with Letters of Credit issued by it or proposed to be issued by
     it and the Letters of Credit Agreements pertaining to the Letters of Credit
     as fully as if the term "Agent", as used in this Article 15, included the
     Issuing Bank with respect to such acts or omissions, and (ii) as
     additionally provided in this Agreement with respect to the Issuing Bank.

     Section 15.2  Delegation of Duties. Agent may execute any of its duties
under this Agreement or any other Loan Document by or through agents, employees,
or attorneys-in-fact and shall be entitled to advice of counsel concerning all
matters pertaining to such duties. Agent shall not be responsible for the
negligence or misconduct of any agent or attorney-in-fact that it selects with
reasonable care.

     Section 15.3  Liability of Agent. No Agent-Related Person shall (i) be
liable for any action taken or omitted to be taken by it under or in connection
with this Agreement or any other Loan Document or the transactions contemplated
hereby (except for such Person's own gross negligence or willful misconduct), or
(ii) be responsible in any manner to any of the Lenders for any recital,
statement, representation, or warranty made by Parent or any Subsidiary or
Affiliate of Parent, or any officer thereof, contained in this Agreement or in
any other Loan Document, or in any certificate,



CREDIT AGREEMENT - Page 84

<PAGE>   91


report, statement, or other document referred to or provided for in, or received
by Agent under or in connection with, this Agreement or any other Loan Document,
or the validity, effectiveness, genuineness, enforceability, or sufficiency of
this Agreement or any other Loan Document, or for any failure of Parent or any
Subsidiary or Affiliate of Parent party to any Loan Document to perform its
obligations hereunder or thereunder. No Agent-Related Person shall be under any
obligation to any Lender to ascertain or to inquire as to the observance or
performance of any of the agreements contained in, or conditions of, this
Agreement or any other Loan Document, or to inspect the properties, books, or
records of Parent or any of Parent's Subsidiaries or Affiliates.

     Section 15.4  Reliance By Agent.

          (a)  Agent shall be entitled to rely, and shall be fully protected in
     relying, upon any writing, resolution, notice, consent, certificate,
     affidavit, letter, telegram, facsimile, telex, or telephone message,
     statement, or other document or conversation believed by it to be genuine
     and correct and to have been signed, sent or made by the proper Person or
     Persons, and upon advice and statements of legal counsel (including,
     without limitation, counsel to Parent and its Subsidiaries), independent
     accountants, and other experts selected by Agent. Agent shall be fully
     justified in failing or refusing to take any action under this Agreement or
     any other Loan Document unless it shall first receive such advice or
     concurrence of the Required Lenders as it deems appropriate and, if Agent
     so requests, it shall first be indemnified to its satisfaction by the
     Lenders against any and all liability and expense which may be incurred by
     Agent by reason of taking or continuing to take any such action. Agent
     shall in all cases be fully protected in acting, or in refraining from
     acting, under this Agreement or any other Loan Document in accordance with
     a request or consent of the Required Lenders and such request and any
     action taken or failure to act pursuant thereto shall be binding upon all
     of the Lenders.

          (b)  For purposes of determining compliance with the conditions
     specified in Section 8.1 and Section 8.2, each Lender that has executed
     this Agreement shall be deemed to have consented to, approved or accepted,
     or to be satisfied with, each document or other matter either sent by Agent
     to such Lender for consent, approval, acceptance, or satisfaction, or
     required thereunder to be consented to or approved by or acceptable or
     satisfactory to the Lender.

     Section 15.5  Notice of Default. Agent shall not be deemed to have
knowledge or notice of the occurrence of any Default or Event of Default, except
with respect to defaults in the payment of principal, interest, and fees
required to be paid to Agent for the account of the Lenders, unless Agent shall
have received written notice from a Lender, Parent, or any Subsidiary of Parent
referring to this Agreement, describing such Default or Event of Default, and
stating that such notice is a "notice of default". Agent will notify the Lenders
of its receipt of any such notice. Agent shall take such action with respect to
such Default or Event of Default as may be requested by the Required Lenders in
accordance with Article 13; provided, however, that unless and until Agent has
received any such request, Agent may (but shall not be obligated to) take such
action, or refrain from taking such action, with respect to such Default or
Event of Default as it shall deem advisable or in the best interest of the
Lenders.



CREDIT AGREEMENT - Page 85

<PAGE>   92


     Section 15.6  Credit Decision. Each Lender acknowledges that none of the
Agent-Related Persons has made any representation or warranty to such Lender,
and that no act by Agent hereinafter taken, including, without limitation, any
review of the affairs of Parent and its Subsidiaries, shall be deemed to
constitute any representation or warranty by any Agent-Related Person to any
Lender. Each Lender represents to Agent that it has, independently and without
reliance upon any Agent-Related Person and based on such documents and
information as it has deemed appropriate, made its own appraisal of and
investigation into the business, prospects, operations, property, financial and
other condition, and creditworthiness of Parent and its Subsidiaries, and all
applicable bank regulatory laws relating to the transactions contemplated
hereby, and made its own decision to enter into this Agreement and to extend
credit to Borrower hereunder. Each Lender also represents that it will,
independently and without reliance upon any Agent-Related Person and based on
such documents and information as such Lender shall deem appropriate at the
time, continue to make its own credit analysis, appraisals, and decisions in
taking or not taking action under this Agreement and the other Loan Documents,
and to make such investigations as it deems necessary to inform itself as to the
business, prospects, operations, property, financial, and other condition and
creditworthiness of Parent and its Subsidiaries. Except for notices, reports,
and other documents expressly herein required to be furnished to the Lenders by
Agent, Agent shall not have any duty or responsibility to provide any Lender
with any credit or other information concerning the business, prospects,
operations, property, financial and other condition, or creditworthiness of
Parent or any of its Subsidiaries which may come into the possession of any of
the Agent-Related Persons. For purposes of determining compliance with Section
8.1, each Lender that has executed this Agreement shall be deemed to have
consented to, approved, or accepted or to be satisfied with, each document or
other matter either sent by Agent to such Lender for consent, approval,
acceptance, or satisfaction, or required thereunder to be consented to or
approved by or acceptable or satisfactory to such Lender.

     Section 15.7  Indemnification. THE LENDERS AGREE TO INDEMNIFY EACH
AGENT-RELATED PERSON (TO THE EXTENT NOT REIMBURSED UNDER SECTION 16.1 OR SECTION
16.2, BUT WITHOUT LIMITING THE OBLIGATIONS OF PARENT AND BORROWER UNDER SUCH
SECTIONS) RATABLY IN ACCORDANCE WITH THEIR RESPECTIVE COMMITMENT PERCENTAGES,
FOR ANY AND ALL LIABILITIES, OBLIGATIONS, LOSSES, DAMAGES, PENALTIES, ACTIONS,
JUDGMENTS, SUITS, COSTS, EXPENSES (INCLUDING, WITHOUT LIMITATION, REASONABLE
ATTORNEYS' FEES), OR DISBURSEMENTS OF ANY KIND AND NATURE WHATSOEVER THAT MAY BE
IMPOSED ON, INCURRED BY OR ASSERTED AGAINST ANY AGENT-RELATED PERSON (INCLUDING,
WITHOUT LIMITATION, BY ANY LENDER) IN ANY WAY RELATING TO OR ARISING OUT OF ANY
LOAN DOCUMENT OR THE TRANSACTIONS CONTEMPLATED THEREBY OR ANY ACTION TAKEN OR
OMITTED BY ANY AGENT- RELATED PERSON UNDER ANY LOAN DOCUMENT; PROVIDED THAT NO
LENDER SHALL BE LIABLE FOR ANY OF THE FOREGOING TO THE EXTENT THEY ARE FOUND IN
A FINAL, NON-APPEALABLE JUDGMENT RENDERED BY A COURT OF COMPETENT JURISDICTION
TO HAVE ARISEN FROM THE GROSS NEGLIGENCE OR WILLFUL MISCONDUCT OF, THE PERSON TO
BE INDEMNIFIED. WITHOUT LIMITING ANY PROVISION OF ANY LOAN DOCUMENT, IT IS THE
EXPRESS INTENTION OF THE PARTIES HERETO THAT EACH PERSON TO BE INDEMNIFIED UNDER
THIS SECTION SHALL BE INDEMNIFIED FROM AND HELD HARMLESS AGAINST ANY AND ALL



CREDIT AGREEMENT - Page 86

<PAGE>   93


LOSSES, LIABILITIES, CLAIMS, DAMAGES, PENALTIES, JUDGMENTS, DISBURSEMENTS,
COSTS, AND EXPENSES (INCLUDING, WITHOUT LIMITATION, ATTORNEYS' FEES) ARISING OUT
OF OR RESULTING FROM THE SOLE OR CONTRIBUTORY NEGLIGENCE OF SUCH PERSON. WITHOUT
LIMITATION OF THE FOREGOING, EACH LENDER AGREES TO REIMBURSE THE APPLICABLE
AGENT- RELATED PERSON PROMPTLY UPON DEMAND FOR ITS RATABLE SHARE (CALCULATED
BASED ON THE COMMITMENT PERCENTAGES) OF ANY COSTS OR EXPENSES PAYABLE BY PARENT
OR BORROWER UNDER SECTION 16.1 TO THE EXTENT THAT SUCH AGENT-RELATED PERSON IS
NOT PROMPTLY REIMBURSED FOR SUCH COSTS AND EXPENSES BY PARENT OR BORROWER. IN
THE CASE OF AN INVESTIGATION, LITIGATION, OR OTHER PROCEEDING TO WHICH THE
INDEMNITY IN THIS SECTION APPLIES, SUCH INDEMNITY SHALL BE EFFECTIVE WHETHER OR
NOT SUCH INVESTIGATION, LITIGATION OR PROCEEDING IS BROUGHT BY ANY LOAN PARTY,
ITS DIRECTORS, SHAREHOLDERS, OR CREDITORS OR ANY PARTY ENTITLED TO
INDEMNIFICATION HEREUNDER OR ANY OTHER PERSON AND WHETHER OR NOT THE
TRANSACTIONS CONTEMPLATED HEREBY ARE CONSUMMATED.

     Section 15.8  Agent in Individual Capacity. Bank of America and its
Affiliates may make loans to, issue letters of credit for the account of, accept
deposits from, acquire equity interests in, and generally engage in any kind of
banking, trust, financial advisory, underwriting, or other business with Parent
and its Subsidiaries and Affiliates as though Bank of America were not Agent or
the Issuing Bank hereunder and without notice to or consent of the Lenders. The
Lenders acknowledge that, pursuant to such activities, Bank of America or its
Affiliates may receive information regarding the Parent, its Subsidiaries, or
its Affiliates (including, without limitation, information that may be subject
to confidentiality obligations in favor of Parent or such Subsidiary or
Affiliate) and acknowledge that Agent shall be under no obligation to provide
such information to the Lenders. With respect to its Loans, Bank of America
shall have the same rights and powers under this Agreement as any other Lender
and may exercise the same as though it were not Agent or the Issuing Bank.

     Section 15.9  Successor Agent. Agent may resign as Agent upon thirty (30)
days prior notice to the Lenders. If Agent resigns under this Agreement, the
Required Lenders shall appoint from among the Lenders a successor agent for the
Lenders, which successor agent shall be approved by Parent. If no successor
agent is appointed prior to the effective date of the resignation of Agent,
Agent may appoint, after consulting with the Lenders and Parent, a successor
agent from among the Lenders. Upon the acceptance of its appointment as
successor agent hereunder, such successor agent shall succeed to all the rights,
powers, and duties of the retiring Agent and the term "Agent" shall mean such
successor agent, and the retiring Agent's appointment, powers, and duties as
Agent shall be terminated. After any retiring Agent's resignation hereunder as
Agent, the provisions of this Article 15 and Section 16.1 and Section 16.2 shall
inure to its benefit as to any actions taken or omitted to be taken by it while
it was Agent under this Agreement. If no successor agent has accepted
appointment as Agent by the date which is thirty (30) days following a retiring
Agent's notice of resignation, the retiring Agent's resignation shall
nevertheless thereupon become effective and the Lenders shall perform all of the
duties of Agent hereunder until such time, if any, as the Required Lenders
appoint a successor agent as provided for above. Notwithstanding the foregoing,



CREDIT AGREEMENT - Page 87

<PAGE>   94


if Agent is also acting as the Issuing Bank, simultaneously with appointment of
a successor agent as provided herein such successor agent shall assume all of
the duties and obligations of the retiring Agent as the Issuing Bank pursuant to
documentation in form and substance satisfactory to the retiring Agent.

     Section 15.10 Withholding Tax.

          (a)  If any Lender is a "foreign corporation, partnership or trust"
     within the meaning of the Code and such Lender claims exemption from, or a
     reduction of, U.S. withholding tax under Section 1441 or Section 1442 of
     the Code, such Lender agrees with and in favor of Agent, to deliver to
     Agent:

               (i)    if such Lender claims an exemption from, or a reduction
          of, withholding tax under a U.S. tax treaty, two properly completed
          and executed copies of IRS Form 1001 before the payment of any
          interest in the first calendar year and before the payment of any
          interest in each third succeeding calendar year during which interest
          may be paid under this Agreement;

               (ii)   if such Lender claims that interest paid under this
          Agreement is exempt from U.S. withholding tax because it is
          effectively connected with a U.S. trade or business of such Lender,
          two properly completed and executed copies of IRS Form 4224 before the
          payment of any interest is due in the first taxable year of such
          Lender and in each succeeding taxable year of such Lender during which
          interest may be paid under this Agreement; and

               (iii)  such other form or forms as may be required under the Code
          or other laws of the U.S. as a condition to exemption from, or
          reduction of, U.S. withholding tax.

     Such Lender agrees to promptly notify Agent of any change in circumstances
     which would modify or render invalid any claimed exemption or reduction.

          (b)  If any Lender claims exemption from, or reduction of, withholding
     tax under a U.S. tax treaty by providing IRS Form 1001 and such Lender
     sells, assigns, grants a participation in, or otherwise transfers all or
     part of the Obligations to another Lender, such assigning Lender agrees to
     notify Agent of the percentage amount in which it is no longer the
     beneficial owner of the Obligations. To the extent of such percentage
     amount, Agent will treat such assigning Lender's IRS Form 1001 as no longer
     valid.

          (c)  If any Lender claiming exemption from U.S. withholding tax by
     filing IRS Form 4224 with Agent sells, assigns, grants a participation in,
     or otherwise transfers all or part of the Obligations to another Lender,
     the assigning Lender agrees to undertake sole responsibility for complying
     with the withholding tax requirements imposed by Sections 1441 and 1442 of
     the Code.



CREDIT AGREEMENT - Page 88

          (d)  If any Lender is entitled to a reduction in the applicable
     withholding tax, Agent may withhold from any interest payment to such
     Lender an amount equivalent to the applicable withholding tax after taking
     into account such reduction. However, if the forms or other documentation
     required by Section 14.10(a) are not delivered to Agent, then Agent may
     withhold from any interest payment to such Lender not providing such forms
     or other documentation an amount equivalent to the applicable withholding
     tax imposed by Section 1441 and Section 1442 of the Code, without
     reduction.

          (e)  If the IRS or any other Governmental Authority of the U.S. or
     other jurisdiction asserts a claim that Agent did not properly withhold tax
     from amounts paid to or for the account of any Lender (because the
     appropriate form was not delivered or was not properly executed, or because
     such Lender failed to notify Agent of a change in circumstances which
     rendered the exemption from, or reduction of, withholding tax ineffective,
     or for any other reason) such Lender shall indemnify Agent fully for all
     amounts paid, directly or indirectly, by Agent as tax or otherwise,
     including, without limitation, penalties and interest and any taxes imposed
     by any jurisdiction on the amounts payable to Agent under this Section
     15.10, together with all costs and expenses (including, without limitation,
     attorney's fees and expenses). The obligation of the Lenders under this
     clause (e) shall survive the payment of the Obligations and the resignation
     or replacement of Agent.

SHAREHOLDERS, OR CREDITORS OR ANY PARTY ENTITLED TO INDEMNIFICATION HEREUNDER OR
ANY OTHER PERSON AND WHETHER OR NOT THE TRANSACTIONS CONTEMPLATED HEREBY ARE
CONSUMMATED.

     Section 16.3  Limitation of Liability. No Agent-Related Person, Lender, or
any Affiliate, officer, director, employee, attorney, or agent thereof shall
have any liability with respect to Parent or Borrower for and, by the execution
of the Loan Documents to which it is a party, each other Loan Party, hereby
waives, releases, and agrees not to sue any of them upon, any claim for, any
special, indirect, incidental, consequential, or punitive damages suffered or
incurred by any Loan Party in connection with, arising out of, or in any way
related to any of the Loan Documents, or any of the transactions contemplated by
any of the Loan Documents.

     Section 16.4  No Duty. All attorneys, accountants, appraisers, and other
professional Persons and consultants retained by any of Agent, Arranger, or any
Lender shall have the right to act exclusively in the interest of Agent,
Arranger, and the Lenders and shall have no duty of disclosure, duty of loyalty,
duty of care, or other duty or obligation of any type or nature whatsoever to
any Loan Party, any shareholders of any Loan Party, or any other Person.

     Section 16.5  No Fiduciary Relationship. The relationship between the Loan
Parties on the one hand and Agent, Arranger, and the Lenders on the other is
solely that of debtor and creditor, and neither any of Agent, Arranger, nor any
Lender has any fiduciary or other special relationship with any Loan Party, and
no term or condition of any of the Loan Documents shall be construed so as to
deem the relationship between the Loan Parties on the one hand and any of Agent,
Arranger, and each Lender on the other to be other than that of debtor and
creditor.

     Section 16.6  Equitable Relief. Each of Parent and Borrower recognizes that
in the event any Loan Party fails to pay, perform, observe, or discharge any or
all of the obligations under the Loan Documents, any remedy at law may prove to
be inadequate relief to Agent and the Lenders. Each of Parent and Borrower
therefore agrees that Agent and the Lenders, if Agent or the Required Lenders so
request, shall be entitled to temporary and permanent injunctive relief in any
such case without the necessity of proving actual damages.

     Section 16.7  No Waiver; Cumulative Remedies. No failure on the part of
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 any Loan Document
shall operate as a waiver thereof, nor shall any single or partial exercise of
any right, power, or privilege under any Loan Document preclude any other or
further exercise thereof or the exercise of any other right, power, or
privilege. The rights and remedies provided for in the Loan Documents are
cumulative and not exclusive of any rights and remedies provided by law.

     Section 16.8  Successors and Assigns.

          (a)  Binding Effect. This Agreement shall be binding upon and inure to
     the benefit of the parties hereto and their respective successors and
     assigns. Neither Parent nor



CREDIT AGREEMENT - Page 91

     Borrower may assign or transfer any of its rights or obligations hereunder
     or under any other Loan Document without the prior written consent of Agent
     and all of the Lenders.

          (b)  Assignment. Each Lender may assign to one or more Persons all or
     a portion of its rights and obligations under this Agreement (including,
     without limitation, all or a portion of its Loans, its Notes, and its
     Commitment); provided, however, that

               (i)    each such assignment shall be to an Eligible Assignee (as
          used herein, "Eligible Assignee" means (A) a Lender; (B) an Affiliate
          of a Lender or, with respect to any Lender that is a fund that invests
          in bank loans, any other fund that invests in bank loans and is
          managed by the same investment advisor as such Lender (herein a
          "Related Fund"); and (C) any other Person approved by Agent and,
          unless an Event of Default has occurred and is continuing at the time
          any assignment is effected in accordance with this Section 16.8,
          Parent and Borrower, such approval not to be unreasonably withheld,
          conditioned, or delayed by Parent or Borrower and such approval to be
          deemed given by Parent and Borrower if no objection is received by the
          assigning Lender and Agent from Parent or Borrower within five (5)
          Business Days after notice of such proposed assignment has been
          provided by the assigning Lender to Agent, Parent, and Borrower;
          provided, however, that neither Parent nor an Affiliate of Parent
          shall qualify as an Eligible Assignee);

               (ii)   any such assignment may be made by a Lender to an Eligible
          Assignee non-ratably with respect to the Loans and Commitments held by
          such assigning Lender;

               (iii)  except in the case of an assignment to another Lender or
          an assignment of all of a Lender's rights and obligations under this
          Agreement or an assignment by a Lender to one of its Related Funds,
          any such partial assignment shall be in an amount at least equal to
          $10,000,000 and any partial assignment to a Related Fund shall be in
          an amount at least equal to $2,000,000;

               (iv)   the parties to any such assignment shall execute and
          deliver to Agent for its acceptance an Assignment and Acceptance,
          together with any Note subject to such assignment and a processing fee
          of $3,500.

         Upon execution, delivery, and acceptance of such Assignment and
         Acceptance, the assignee thereunder shall be a party hereto and, to
         the extent of such assignment, have the obligations, rights, and
         benefits of a Lender hereunder and the assigning Lender shall, to the
         extent of such assignment, relinquish its rights and be released from
         its obligations under this Agreement. Upon the consummation of any
         assignment pursuant to this Section 16.8, the assignor, Agent, and
         Borrower shall upon return of the assignor's Notes, if any, make
         appropriate arrangements so that, if required, new Notes are issued to
         the assignor and the assignee. If the assignee is not incorporated
         under the laws of the U.S. or a state thereof, it shall deliver to
         Borrower and Agent certification as to exemption from deduction or
         withholding of Taxes in accordance with Section 15.10.



CREDIT AGREEMENT - Page 92

          (c)  Amendment of Schedule 1.1. Upon execution, delivery, and
     acceptance of an Assignment and Acceptance, Schedule 1.1 shall be deemed to
     be automatically amended to reflect the resulting Commitments of the
     Lenders after giving effect to such Assignment and Acceptance; provided
     that the Commitments of the Lenders not a party to such Assignment and
     Acceptance shall not be affected as a result of such amendment to Schedule
     1.1.

          (d)  Register. Agent shall maintain at the Principal Office a copy of
     each Assignment and Acceptance delivered to and accepted by it and a
     register for the recordation of the names and addresses of the Lenders and
     the Commitment of, and principal amount of the Loans owing to, each Lender
     from time to time (the "Register"). The entries in the Register shall be
     conclusive and binding for all purposes, absent manifest error, and
     Borrower, Agent, and the Lenders may treat each Person whose name is
     recorded in the Register as a Lender hereunder for all purposes of this
     Agreement. The Register shall be available for inspection by Borrower or
     any Lender at any reasonable time and from time to time upon reasonable
     prior notice. Upon its receipt of an Assignment and Acceptance executed by
     the parties thereto, together with any Note or Notes subject to such
     assignment and payment of the processing fee, Agent shall, if such
     Assignment and Acceptance has been completed, (i) accept such Assignment
     and Acceptance, (ii) record the information contained therein in the
     Register, and (iii) give prompt notice thereof to the parties thereto.

          (e)  Participations. Each Lender may sell participations to one or
     more Persons in all or a portion of its rights and obligations under this
     Agreement (including, without limitation, all or a portion of its
     Commitment and its Loans); provided, however, that (i) such Lender's
     obligations under this Agreement shall remain unchanged, (ii) such Lender
     shall remain solely responsible to the other parties hereto for the
     performance of such obligations, (iii) the participant shall be entitled to
     the benefit of the yield protection provisions contained in Article 6 (to
     the extent that the Lender selling such participation would have been
     entitled thereto) and the right of set-off contained in Section 13.5, and
     (iv) Parent and Borrower shall continue to deal solely and directly with
     such Lender in connection with such Lender's rights and obligations under
     this Agreement, and such Lender shall retain the sole right to enforce the
     obligations of Parent and Borrower relating to the Loans and to approve any
     amendment, modification, waiver, or consent of any provision of any Loan
     Document (other than amendments, modifications, waivers, or consents of the
     types relating to the Loan or Commitment participated in under Section
     16.11(a) and Section 16.11(b)).

          (f)  Pledge to Federal Reserve. Notwithstanding any other provision
     set forth in this Agreement, any Lender may at any time assign and pledge
     all or any portion of its Loans to any Federal Reserve Bank as collateral
     security pursuant to Regulation A of the Board of Governors of the Federal
     Reserve System (as the same may be amended, modified, or supplemented from
     time to time or any successor regulation therefor) and any Operating
     Circular issued by such Federal Reserve Bank. No such assignment shall
     release the assigning Lender from its obligations hereunder.



CREDIT AGREEMENT - Page 93

<PAGE>   100

          (g)  Delivery of Information. Any Lender may furnish any information
     concerning any Loan Party in the possession of such Lender from time to
     time to assignees and including, without limitation, prospective assignees
     and participants) subject to such Persons agreeing to being bound by the
     provisions of Section 16.20.

     Section 16.9  Survival. All representations and warranties made by any Loan
Party in any Loan Document or in any document, statement, or certificate
furnished in connection with any Loan Document shall survive the execution and
delivery of the Loan Documents and no investigation by Agent or any Lender or
any closing shall affect the representations and warranties or the right of
Agent and the Lenders to rely upon them. Without prejudice to the survival of
any other obligation of Parent or Borrower hereunder, the obligations under
Article 6, Section 15.5, Section 16.1, and Section 16.2 shall survive repayment
of the Notes and termination of the Commitments and the Letters of Credit.

     Section 16.10 Entire Agreement. THIS AGREEMENT, THE NOTES, AND THE OTHER
LOAN DOCUMENTS REFERRED TO HEREIN EMBODY THE FINAL, ENTIRE AGREEMENT AMONG THE
PARTIES HERETO AND SUPERSEDE ANY AND ALL PRIOR COMMITMENTS, AGREEMENTS,
REPRESENTATIONS, AND UNDERSTANDINGS, WHETHER WRITTEN OR ORAL, RELATING TO THE
SUBJECT MATTER HEREOF AND MAY NOT BE CONTRADICTED OR VARIED BY EVIDENCE OF
PRIOR, CONTEMPORANEOUS, OR SUBSEQUENT ORAL AGREEMENTS OR DISCUSSIONS OF THE
PARTIES HERETO. THERE ARE NO UNWRITTEN ORAL AGREEMENTS AMONG THE PARTIES HERETO.

     Section 16.11 Amendments and Waivers. Any provision of any Loan Document
may be amended or waived and any consent to any departure by any Loan Party
therefrom may be granted if, but only if, such amendment, waiver, or consent is
in writing and is signed by Parent, Borrower, and the Required Lenders (and, if
Article 15 or the rights or duties of Agent are affected thereby, by Agent);
provided that no such amendment, waiver, or consent applicable to:

          (a)  a Loan, Letter of Credit, or Commitment which has the effect of

               (i)    increasing such Commitment,

               (ii)   reducing the principal of or rate of interest on such Loan
          or any Reimbursement Obligation relating to such Letter of Credit or
          any fees or other amounts payable hereunder with respect to such Loan,
          Letter of Credit, or Commitment,

               (iii)  postponing any date fixed for the payment of any scheduled
          installment of principal of or interest on such Loan or any
          Reimbursement Obligation relating to such Letter of Credit or any fees
          or other amounts payable hereunder with respect to such Loan, Letter
          of Credit, or Commitment or changing any optional or mandatory
          prepayment provision applicable to such Loan or Letter of Credit, or



CREDIT AGREEMENT - Page 94

<PAGE>   101

               (iv)   postponing any date fixed for termination of such
          Commitment

     shall be effective unless also signed by each Lender holding (with respect
     to Letters of Credit either directly or through a participation under
     Section 2.6(a)) the Loan, Letter of Credit, or Commitment of the type being
     modified; and

          (b)  any change (including a waiver)

               (i)    in the definition of Required Lenders or the provisions of
          this Section 16.11,

               (ii)   in the conditions specified in Article 8,

               (iii)  which has the effect of releasing any Loan Party in a
          transaction which is not otherwise permitted hereby,

               (iv)   which releases all or substantially all of the Collateral,

               (v)    which releases the Guaranty of Parent, or

               (vi)   which releases all or substantially all of the Guaranties
          of the Guarantors, other than Parent,

     shall not be effective unless signed by all Lenders.

     Section 16.12 Maximum Interest Rate.

          (a)  No interest rate specified in any Loan Document (the "Contract
     Rate") shall at any time exceed the Maximum Rate. If at any time the
     Contract Rate for any Obligation shall exceed the Maximum Rate, thereby
     causing the interest accruing on such Obligation to be limited to the
     Maximum Rate, then any subsequent reduction in the Contract Rate for such
     Obligation shall not reduce the rate of interest on such Obligation below
     the Maximum Rate until the aggregate amount of interest accrued on such
     Obligation equals the aggregate amount of interest which would have accrued
     on such Obligation if the Contract Rate for such Obligation had at all
     times been in effect.

          (b)  No provision of any Loan Document shall require the payment or
     the collection of interest in excess of the Maximum Rate. If any excess of
     interest in such respect is hereby provided for, or shall be adjudicated to
     be so provided, in any Loan Document or otherwise in connection with this
     loan transaction, the provisions of this Section shall govern and prevail
     and neither Borrower nor the sureties, guarantors, successors, or assigns
     of Borrower shall be obligated to pay the excess amount of such interest or
     any other excess sum paid for the use, forbearance, or detention of sums
     loaned pursuant hereto. In the event any Lender ever receives, collects, or
     applies as interest any such sum, such amount which would be in excess of
     the Maximum Rate shall be applied as



CREDIT AGREEMENT - Page 95

<PAGE>   102


     a payment and reduction of the principal of the Obligations, and, if the
     principal of the Obligations has been paid in full, any remaining excess
     shall forthwith be paid to Borrower. In determining whether or not the
     interest paid or payable exceeds the Maximum Rate, Borrower and each Lender
     shall, to the extent permitted by applicable law, (a) characterize any
     non-principal payment as an expense, fee, or premium rather than as
     interest, (b) exclude voluntary prepayments and the effects thereof, and
     (c) amortize, prorate, allocate, and spread in equal or unequal parts the
     total amount of interest throughout the entire contemplated term of the
     Obligations so that interest for the entire term does not exceed the
     Maximum Rate.

     Section 16.13 Notices. All notices and other communications provided for
in any Loan Document to which any Loan Party is a party shall be given or made
in writing (except as otherwise permitted by Section 5.3) and telecopied, mailed
by certified mail return receipt requested, or delivered to the intended
recipient at the "Address for Notices" specified below its name on Schedule
16.13 or with respect to any Loan Party, at the "Address for Notices" specified
below Borrower's name on Schedule 16.13, or with respect to a Lender not a party
to this Agreement on the Closing Date, in its Assignment and Acceptance, or, as
to any party at such other address as shall be designated by such party in a
notice to each other party given in accordance with this Section. Except as
otherwise provided in any Loan Document, all such communications shall be deemed
to have been duly given when transmitted by telecopy, subject to telephone
confirmation of receipt, or when personally delivered or, in the case of a
mailed notice, three (3) Business Days after being duly deposited in the mails,
in each case given or addressed as aforesaid; provided, however, notices to
Agent pursuant to Section 2.6 or Section 5.3 shall not be effective until
received by Agent. Any agreement of Agent and the Lenders herein to receive
certain notices by telephone or telecopy is solely for the convenience and at
the request of Parent and Borrower. Agent, the Lenders, and the Issuing Bank
shall be entitled to rely on the authority of any Person purporting to be a
Person authorized by Parent or Borrower to give such notice and neither Agent,
any Lender, nor the Issuing Bank shall have any liability to Parent or Borrower
or any other Person on account of any action taken or not taken by Agent, any
Lender, or the Issuing Bank in reliance upon such telephonic or telecopy notice.
The obligation of Borrower to repay the Loans and pay the Reimbursement
Obligations shall not be affected in any way or to any extent by any failure of
Agent, any Lender, or the Issuing Bank to receive written confirmation of any
telephonic or telecopy notice or the receipt by Agent, any Lender, or the
Issuing Bank of a confirmation which is at variance with the terms understood by
