                                     - 5 -
<PAGE>

by the "Year 2000 Problem" (that is, the risk that computer applications used by
Borrower or any of its respective Related Entities or its respective suppliers
and vendors may be unable to recognize and perform properly date-sensitive
functions involving certain dates prior to and after December 31, 1999); (ii)
developed a plan and a timetable for addressing the Year 2000 Problem on a
timely basis; and (iii) to date, implemented that plan in accordance with that
timetable. Borrower reasonably believes that all computer applications
(including those of their suppliers and vendors) that are material to the
business and operations of Borrower or any of its Related Entities 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 to
the extent that a failure to do so could not reasonably be expected to have a
material adverse effect on the business, operations, creditworthiness or
financial status of Borrower or any of its Related Entities.

maintained, or to which contributions have been made, by Borrower which is

deficiency" (as such term is defined in Section 302 of ERISA) as of the last day
of the most recent fiscal year of such plan ended prior to the date hereof, or
would have had such an accumulated funding deficiency on such day if such year
were the first year of such plan to which such Part 3 applied; and no material
liability to the Pension Benefit Guaranty Corporation has been incurred with
respect to any such plan by Borrower.

          j. SURVIVAL OF REPRESENTATIONS AND WARRANTIES. Borrower understands
and agrees that Bank, without independent investigation, is relying upon the
above representations and warranties in extending advances to Borrower under the
Loan. Borrower further agrees that the foregoing representations and warranties
shall be continuing in nature and shall remain in full force and effect until
such time as the Loan shall be paid in full, or until this Agreement shall be
terminated in the manner provided herein, whichever is the last to occur.

     6. AFFIRMATIVE COVENANTS. Borrower will:

          a. EXISTENCE AND COMPLIANCE. Maintain its existence, good standing and
qualification to do business where required, and preserve and keep in force all
licenses, permits, and franchises necessary for the proper conduct of its
business, and comply with all laws, regulations and governmental requirements
including, without limitation, Environmental Laws applicable to it or to any of
its property, business operations and transactions.

          b. TAXES. Duly pay and discharge all taxes, assessments, and
governmental charges upon Borrower or against Borrower's property before the

FOR VALUE RECEIVED, the undersigned Borrower unconditionally promises to pay to
the order of Bank, its successors and assigns, without setoff, at its offices
indicated at the beginning of this Note, or at such other place as may be
designated by Bank, the principal amount of TWENTY FIVE MILLION AND NO/100
DOLLARS ($25,000,000.00), or so much thereof as may be advanced from time to
time, in immediately available funds, together with interest computed daily on
the outstanding principal balance hereunder, at an annual interest rate, and in
accordance with the payment schedule, indicated below.

1.   AMENDED AND RESTATED NOTE. This Amended and Restated Revolving Promissory
     Note ("Note") is given in renewal of that that certain Promissory Note,
     dated July 28, 1997 and executed by Borrower to and in favor or Barnett
     Bank, N.A., in the original principal amount of TEN MILLION AND NO/100
     DOLLARS ($10,000,000.00) (the "Original Note"). It is the intention of
     Borrower and Bank that this Note shall not extinguish the Original Note;
     however, the indebtedness represented by the Original Note will be paid in
     accordance with the terms and conditions provided herein. This Note is also
     given to enlarge the outstanding principal balance of the Original Note to
     TWENTY FIVE MILLION AND NO/100 DOLLARS ($25,000,000.00) and to amend and
     restate certain other provisions of the Original Note.

2.   RATE. The outstanding principal balance of this Note shall bear interest at
     a fixed interest rate per annum equal to the Fixed Adjusted LIBOR Rate (as
     defined below), plus seventy-five (75) basis points (0.75%) (the "Fixed
     Rate"). The Fixed Adjusted LIBOR Rate shall be fixed at the beginning of
     each Interest Period (as defined below). Each Interest Period shall begin
     on the first (1st) Business Day (as defined below) of each calendar month.

     As used herein, the following terms shall have the respective meanings set
     forth below:

          a. "BUSINESS DAY" means a banking day which shall be a day on which
     Bank is open for the transaction of domestic and foreign exchange business
     in both Fort Lauderdale, Florida and Charlotte, North Carolina and on which
     the London Interbank Market is open for the transaction of foreign exchange
     business, excluding any national holidays, and any performance which would
     otherwise be required on a day other than a banking day shall be timely
     performed in such instance, if performed on the next succeeding banking
     day.

          b. "FIXED ADJUSTED LIBOR RATE" means a rate per annum equal to the sum
     of (a) the quotient of (i) the LIBOR Rate (as hereinafter defined), divided
     by (ii) the remainder of 1.00 minus the LIBOR Reserve Requirement (as
     hereinafter defined), plus (b) the net assessment rate (expressed as a
     percentage rounded to the next highest .01 of 1%) which is in effect on
     such day [under the regulations of the Federal Deposit Insurance
     Corporation ("FDIC") or its successor] for determining the assessments paid
     by Bank to the FDIC for insuring time deposits made in dollars at Bank's
     principal offices in Tampa, Florida. The computation of the Fixed Adjusted
     LIBOR Rate shall include adjustments in respect of impositions 

<PAGE>

     or assessments on Bank for FDIC insurance or other insurance or other fees,
     reserves, assessments and surcharges which occur for insuring time deposits
     or because of the sale of a related deposit.


          c. "INTEREST PERIOD" means the time period during which the Fixed Rate
     (as such term is defined in the first paragraph of this Section 2) shall
     apply, which time period shall be a thirty (30) day period and shall begin
     on the first (1st) Business Day of each calendar month. 

          d. "LIBOR RATE" means the rate of interest per annum equal to the
     interest settlement rate for U.S. Dollars as published by the British
     Bankers Association as of 11:00 a.m. London time two (2) Business Days
     before the first day of the Interest Period and for a period comparable to
     the applicable Interest Period. 

          e. "LIBOR RESERVE REQUIREMENT" means on any day, that percentage
     (expressed as a decimal fraction) which is in effect on such date, as
     provided by the Federal Reserve System for determining the maximum reserve
     requirements generally applicable to financial institutions regulated by
     the Federal Reserve Board (including, without limitation, basic
     supplemental, marginal and emergency reserves) under Regulation D with
     respect to "Eurocurrency liabilities" as currently defined by Regulation D,
     or under any similar or successor regulation with respect to Eurocurrency
     liabilities or Eurocurrency funding (or other category of liabilities which
     includes deposits by reference to which the interest rate is determined or
     any category or extensions of credit which includes loans by a non-United
     States office of Bank to United States residents). Each determination by
     Bank of the LIBOR Reserve Requirement, shall, in the absence of manifest
     error, be conclusive and binding. 

Notwithstanding any provision of this Note, Bank does not intend to charge and
Borrower shall not be required to pay any amount of interest or other charges in
excess of the maximum permitted by the applicable law of the State of Florida;
if any higher rate ceiling is lawful, then that higher rate ceiling shall apply.
Any payment in excess of such maximum shall be refunded to Borrower or credited
against principal, at the option of Bank.

3.   ACCRUAL METHOD. Unless otherwise indicated, interest at the Rate set forth
     above will be calculated by the 365/360 day method (a daily amount of
     interest is computed for a hypothetical year of 360 days; that amount is
     multiplied by the actual number of days for which any principal is
     outstanding hereunder).

4.   RATE CHANGE DATE. Any Rate based on a fluctuating index or base rate will
     change, unless otherwise provided, each time and as of the date that the
     index or base rate changes. In the event any index is discontinued, Bank
     shall substitute an index determined by Bank to be comparable, in its sole
     discretion. 

5.   PAYMENT SCHEDULE. All payments received hereunder shall be applied first to
     the payment of any expense or charges payable hereunder or under any other
     loan documents executed in connection with this Note, then to interest due
     and payable, with the balance applied to principal, or in such other order
     as Bank shall determine at its option.

     SINGLE PRINCIPAL PAYMENT. Principal shall be paid in full in a single
     payment on November 30, 2001. Interest thereon shall be paid monthly,
     commencing on January 28, 1999, and continuing on the same day of each
     successive month thereafter, with a final payment of all unpaid interest at
     the stated maturity of this Note.

6.   REVOLVING FEATURE. Borrower may borrow, repay and reborrow hereunder at any
     time, up to a maximum aggregate amount outstanding at any one time equal to
     the principal amount of this Note, provided that Borrower is not in default
     under any provision of this Note, any other Loan Documents executed in
     connection with this Note, or any other note or other loan documents now or
     hereafter executed in connection with any other obligation of Borrower to
     Bank, and provided that the borrowings hereunder do not exceed any
     borrowing base or other limitation on borrowings by Borrower and are in
     accordance with the terms of the Loan Documents. Bank shall incur no
     liability for its refusal to advance funds based upon its determination
     that any conditions of such further advances have not been met. Bank
     records of the amounts borrowed from time to time shall be conclusive proof
     thereof.

7.   AUTOMATIC PAYMENT. Borrower has elected to authorize Bank to effect payment
     of sums due under this Note by means of debiting Borrower's account number
     2835559595. This authorization shall not affect the obligation of Borrower
     to pay such sums when due, without notice, if there are insufficient funds
     in such account to make such payment in full on the due date thereof, or if
     Bank fails to debit the account.

     obligations of any Obligors or be construed as a waiver by Bank of, or
     otherwise affect, any of Bank's rights under this Note, under any
     indorsement or guaranty of this Note or under any of the Loan Documents;
     and (c) agree to pay, on demand, all costs and expenses of collection or

     untrue or materially misleading; (f) the failure of any Obligor to timely
     deliver such financial statements, including tax returns, other statements

13.  REMEDIES UPON DEFAULT. Whenever there is a default under this Note (a) the
     entire balance outstanding hereunder and all other obligations of any
     Obligor to Bank (however acquired or evidenced) shall, at the option of
     Bank, become immediately due and payable and any obligation of Bank to
     permit further borrowing under this Note shall immediately cease and
     terminate, and/or (b) to the extent permitted by law, the Rate of interest
     on the unpaid principal shall be increased at Bank's discretion up to the
     maximum rate allowed by law, or if none, 25% per annum (the "Default
     Rate"). The provisions herein for a Default Rate shall not be deemed to
     extend the time for any payment hereunder or to constitute a "grace period"


                                     - 3 -
<PAGE>

     giving Obligors a right to cure any default. At Bank's option, any accrued
     and unpaid interest, fees or charges may, for purposes of computing and
     accruing interest on a daily basis after the due date of the Note or any
     installment thereof, be deemed to be a part of the principal balance, and
     interest shall accrue on a daily compounded basis after such date at the
     Default Rate provided in this Note until the entire outstanding balance of
     principal and interest is paid in full. Upon a default under this Note,
     Bank is hereby authorized at any time, at its option and without notice or
     demand, to set off and charge against any deposit accounts of any Obligor
     (as well as any money, instruments, securities, documents, chattel paper,
     credits, claims, demands, income and any other property, rights and
     interests of any Obligor), which at any time shall come into the possession
     or custody or under the control of Bank or any of its agents, affiliates or
     correspondents, any and all obligations due hereunder. Additionally, Bank
     shall have all rights and remedies available under each of the Loan
     Documents, as well as all rights and remedies available at law or in
     equity. Any judgment rendered on this Note shall bear interest at the
     highest rate of interest permitted pursuant to Chapter 687, Florida
     Statutes. 

14.  NON-WAIVER. The failure at any time of Bank to exercise any of its options
     or any other rights hereunder shall not constitute a waiver thereof, nor
     shall it be a bar to the exercise of any of its options or rights at a
     later date. All rights and remedies of Bank shall be cumulative and may be
     pursued singly, successively or together, at the option of Bank. The
     acceptance by Bank of any partial payment shall not constitute a waiver of
     any default or of any of Bank's rights under this Note. No waiver of any of
     its rights hereunder, and no modification or amendment of this Note, shall
     be deemed to be made by Bank unless the same shall be in writing, duly
     signed on behalf of Bank; each such waiver shall apply only with respect to
     the specific instance involved, and shall in no way impair the rights of
     Bank or the obligations of Obligors to Bank in any other respect at any
     other time. 

15.  APPLICABLE LAW, VENUE AND JURISDICTION. This Note and the rights and
     obligations of Borrower and Bank shall be governed by and interpreted in
     accordance with the law of the State of Florida. In any litigation in
     connection with or to enforce this Note or any indorsement or guaranty of

                            NEGATIVE PLEDGE AGREEMENT

     THIS NEGATIVE PLEDGE AGREEMENT dated as of December 9, 1998, by and between
NATIONSBANK, N.A. ("Bank") whose mailing address is 390 North Orange Avenue, 7th
Floor, Orlando, Florida 32801 and BRITE VOICE SYSTEMS, INC., a Kansas
corporation ("Borrower"), whose address is 250 International Parkway, Suite 300,
Heathrow, Florida 32746.

                                   WITNESSETH:

     WHEREAS, Borrower desires to modify and increase the principal amount of an
existing loan from Bank to Borrower, dated as of even date herewith (together
with all extensions and renewals thereof hereafter referred to as the "Loan"),
in order to finance its working capital needs; and

     WHEREAS, Bank is willing to modify and increase the Loan provided Borrower
agrees not to encumber Borrower's real or personal property.

     NOW, THEREFORE, for and in consideration of the Loan made or to be made by
Bank to Borrower, and for other good and valuable consideration, the receipt and
sufficiency of which is hereby acknowledged by both Borrower and Bank, the
parties hereto do agree as follows:

     1. PROPERTY  Borrower hereby agrees that, for so long as any part of the
Loan remains outstanding, that it will not, without first obtaining the prior
written consent of Bank, create or permit any lien, encumbrance, charge, or
security interest of any kind to exist on:

          Any real or personal property now owned or hereinafter acquired by
          Borrower (the "Property"), nor will Borrower transfer, sell, assign or
          in any manner dispose of the Property or any interest therein (except
          for statutory liens incurred in the ordinary course 

<PAGE>

          of Borrower's business and easements, rights of way and similar rights
          granted in connection with the provision of utilities to the Property
          or in connection with any construction on the Property).

     2. RECORDING. Bank is hereby authorized and permitted to cause this
instrument, and notice hereof, to be recorded and filed at such times and at
such places as Bank, at its option, may elect.

     3. REPRESENTATIONS AND WARRANTIES OF BORROWER. Borrower represents and
warrants to Bank as follows:

          (i)  Borrower is a corporation duly organized and validly existing and
               in good standing under the laws of the State of Kansas and has
               all requisite power and authority to enter into this Agreement.

          (ii) The execution and delivery by Borrower of this Agreement and the
               performance of the respective obligations hereunder and
               thereunder have been duly authorized. This Agreement constitutes
               the legal valid and binding obligation of Borrower enforceable in
               accordance with their terms. The execution and delivery of this
               Agreement and the compliance with the provisions thereof will not
               conflict with or constitute a breach of, or default under, any of
               the provisions of any other agreement to which the Borrower is a
               party.

          (iii) The continued validity in all respects of the aforesaid
               representations and warranties shall be a condition precedent to
               Bank's obligation to fund the Loan. If any of the representations
               and warranties shall not be correct at the time the same is made
               or at the time a request for an advance under the Loan is made,
               Bank will be under no obligation to make any such advance under
               the Loan. 

     4. DEFAULT. Any failure by Borrower to comply with the terms of this
Agreement shall constitute an event of default under the documents evidencing
the Loan and the Borrower agrees that in such event Bank shall have the right in
addition to such other remedies as may be available to it, to injunctive relief
enjoining such breach of this Agreement and neither Borrower, its officers,
directors, employees, agents or representatives shall urge that such remedy is
not appropriate under the circumstances, it being expressly acknowledged by
Borrower that such action shall cause Bank irreparable damage for which legal
remedies are inadequate to protect Bank.

     5. TERMINATION. This Agreement shall remain in full force and effect until
the Loan described above shall have been paid in full, or until sooner
terminated by Bank.


                                       2

     IN WITNESS WHEREOF, the parties hereto have caused this Agreement to be

the, Florida Statutes, as amended, and other applicable laws and regulations;
and

     WHEREAS, Bank and Borrower have each been advised by, or have had the
