**Fiscal 1998 net sales, loss from operations and net loss were impacted by
adoption of the American Institute of Certified Public Accountants' Statement
of Position 97-2 (SOP 97-2), tightening of certain of the Company's credit
practices, non-recurring expense items and a non-recurring charge resulting
from a portion of the price paid by the Company to Integrated Telephony
Products, Inc. for its ESP product line having been attributed to in-process
research and development. Without these items, net sales in fiscal 1998 would
have been $107.8 million. Income from Operations would have been $2.6 million,
and net income would have been $2.4 million, or $0.08 per share.

***Fiscal 1997 income from operations and net income were impacted by charges
totaling approximately $1.8 million and $1.3 million, respectively, or $0.04 per
share, resulting from a non-recurring litigation settlement. Without this
charge, net income for fiscal 1997 would have been $0.43 per share.

****Fiscal 1995 income from operations and net income were impacted by a
non-recurring charge totaling approximately $10.5 million, or $0.32 per share,
associated with a significant portion of the purchase price of VoicePlex
Corporation having been attributed to in-process research and development.
Without this charge, earnings for fiscal 1995 would have been $0.40 per share.

                         REPORT OF INDEPENDENT AUDITORS

Stockholders and Board of Directors
InterVoice, Inc.

We have audited the accompanying consolidated balance sheets of InterVoice, Inc.
and subsidiaries as of February 28, 1999 and 1998 and the related consolidated
statements of operations, changes in stockholders' equity and cash flows for
each of the three years in the period ended February 28, 1999. Our audits also
included the financial statement schedule listed in the index at item 14(a).
These financial statements and schedule are the responsibility of the Company's
management. Our responsibility is to express an opinion on these financial
statements and schedule based on our audits.

We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.

In our opinion, the consolidated financial statements referred to above present
fairly, in all material respects, the consolidated financial position of
InterVoice, Inc. and subsidiaries at February 28, 1999 and 1998, and the
consolidated results of their operations and their cash flows for each of the
three years in the period ended February 28, 1999, in conformity with generally
accepted accounting principles. Also, in our opinion, the related financial
statement schedule, when considered in relation to the basic financial
statements taken as a whole, presents fairly in all material respects the
information set forth therein.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

NOTE A - DESCRIPTION OF BUSINESS

InterVoice, Inc. (together with its subsidiaries, collectively referred to as
"InterVoice" or the "Company") develops, sells and services call automation
systems. The Company's historical emphasis has been on interactive voice
response ("IVR") systems, which allow individuals a self help facility using
their telephones, personal computers, credit card terminals or voices to access
and/or provide information to computer data bases utilized by businesses. More
recently, the Company has focused on systems for telecommunications network
operators which provide a variety of automated services such as processing
collect and credit card calls, and advanced calling features such as prepaid
calling cards, voice and text messaging, one number personal numbering plans
and voice dialing. In the last year, the Company has increased its emphasis on
customer relationship management systems which provide companies automated
customer service, telemarketing capabilities and the ability to generate sales
without human interaction, (i.e., v-commerce and e-commerce). The Company's
products include software development tools designed to support a number of
diverse product applications and to simplify system customization. The Company
sells its products directly to end-users and through more than 130 domestic and
international distributors.

NOTE B - SIGNIFICANT ACCOUNTING POLICIES

PRINCIPLES OF CONSOLIDATION: The consolidated financial statements include the
accounts of InterVoice and its subsidiaries. All significant intercompany
transactions and accounts have been eliminated in consolidation.

USE OF ESTIMATES: The preparation of financial statements in conformity with
generally accepted accounting principles requires management to make certain
estimates and assumptions that affect the amounts reported in the financial
statements and accompanying notes. Actual results could differ from those
estimates.

CASH AND CASH EQUIVALENTS: Cash equivalents include investments in highly
liquid securities with a maturity of three months or less at the time of
acquisition. The carrying amount of these securities approximates fair market
value.

INVENTORIES: Inventories, primarily system components, are valued at the lower
of cost or market with cost determined on a first-in, first-out basis. Amounts
presented are net of inventory obsolescence reserves totaling $1,204,526 and
$1,360,000 at February 28, 1999 and 1998, respectively.

PROPERTY AND EQUIPMENT: Property and Equipment is stated on the basis of cost.
Depreciation is provided by the straight-line method over each asset's
estimated useful life. The range of useful lives by major category are:
buildings: 5 to 40 years; computer equipment: 3 to 5 years; furniture, fixtures
and other: 5 years; and service equipment: 3 years. Depreciation expense
totaled $9,260,774, $8,573,956 and $4,124,289 in fiscal 1999, 1998 and 1997,
respectively. The large increase in depreciation expense in fiscal 1998 versus
the prior fiscal year is associated with the purchase and implementation of a
new Oracle based, enterprise-wide management information system. This year 2000
compliant system is expected to support the Company's future growth.

INTANGIBLE ASSETS: Intangible assets, which include patent licenses, purchased
software and license fees for technologies, such as text to speech and speech
recognition, are being amortized by the straight-line method based on the
Company's assessment of each asset's useful life. Useful lives range from five
to twelve years. Amortization expense for these items totaled $1,751,863,
$1,136,641 and $822,087 in fiscal 1999, 1998 and 1997, respectively. The
increase in amortization expense in fiscal 1999 versus prior fiscal years is
associated with the start of amortization of the assets purchased from
Integrated Telephony products, Inc. and Dronen Consulting, Incorporated (see
Note C).

Costs of internally developed software products and substantial enhancements to
existing software products are expensed until technological feasibility is
established, at which time any additional costs would be capitalized in
accordance with Statement of Financial Accounting Standards (SFAS) No. 86.
Technological feasibility of a computer software product is established when
the Company has completed all planning designing, coding, and testing
activities that are necessary to establish that the product can be produced to
meet its design specifications



                                       10

<PAGE>   11


including functions, features, and technical performance requirements. No costs
have been capitalized to date for internally developed software products and
enhancements as the Company's current process for developing software is
essentially completed concurrently with the establishment of technological
feasibility. The Company capitalizes purchased software upon acquisition when
such software is technologically feasible or if it has an alternative future
use, such as use of the software in different products, resale of the purchased
software, or use of the software internally.

IMPAIRMENT OF ASSETS: The Company records impairment losses on long-lived
assets used in operations when events and circumstances indicate that the
assets might be impaired and the undiscounted cash flows estimated to be
generated by those assets are less than the carrying amounts of those assets.

REVENUE RECOGNITION: The Company recognizes revenue at the time of shipment for
sales of systems which do not require customization to be performed by the
Company. Subsequent to December 1, 1997, revenue for systems which require
customization to be performed by the Company are recognized by the contract
method of accounting, using percentage of completion for larger, more complex
systems (generally over a $500,000 sales price). Progress toward completion is
measured using work hours or days incurred as a percentage of total estimated
hours or days for each contract. Unbilled receivables accrued under percentage
of completion contracts amounted to $5.8 million and $0 at February 28, 1999
and 1998, respectively. The completed contract method is used for smaller
systems. Prior to December 1, 1997, the Company recognized revenue on systems
requiring customization to be performed by the Company at the date of shipment
or at the point after shipment when the remaining obligations of the Company
became insignificant. The change in accounting was required by the American
Institute of Certified Public Accountant's Statement of Position 97-2 which was
required to be applied prospectively for transactions entered into after the
Company's December 1, 1997 date of adoption. No restatement of prior periods or
cumulative effect adjustment was permitted.

The Company recognizes revenue from services at the time the service is
performed or over the period of the contract for maintenance/support.

INCOME TAXES: Deferred income taxes are recognized using the liability method
and reflect the tax impact of temporary differences between the amounts of
assets and liabilities for financial reporting purposes and such amounts as
measured by tax laws and regulations.

RECLASSIFICATIONS: Certain prior year balances have been reclassified to
conform to current year presentation.

NOTE C - INTANGIBLE ASSETS

On September 15, 1998, the Company purchased a computer telephony software
suite from Dronen Consulting, Incorporated for $3,533,723 in cash and 75,000
shares of the Company's stock valued at $1,518,750. The transaction was
accounted for as an asset purchase. The full purchase price of $5,052,473 is
being amortized over the software suite's estimated useful life of five years.

The Company purchased the Enhanced Services Platform (ESP) product line and
certain other assets from Integrated Telephony Products, Inc. on February 26,
1998 in a transaction accounted for as a purchase. This purchase price of
$5,188,071 was comprised of $4,612,500 in cash, Company common stock valued at
$500,000 and other direct acquisition costs totaling $75,571. The allocation of
the purchase price among the identifiable tangible and intangible assets was
based on the fair market value of those assets using a risk adjusted income
approach. Based on appraised value, a portion of the purchase price was
allocated to two purchased research and development projects. The amount
allocated to the purchased research and development projects was expensed at
the time of acquisition as the Company determined that the purchased research
and development projects had not reached technological feasibility based on the
status of design and development activities that required further refinement
and testing. To determine the fair market value of the in-process research and
development projects, the Company used a risk adjusted income approach, in
which fair market value is a function of the future revenues expected to be
generated by an asset, net of all allocable expenses. In determining the amount
of the purchase price to allocate to the purchased research and development
projects, factors such as stage of completion and technological uncertainties
were considered by the Company in determining the present value of the future
benefits to be received. The development activities required to complete the
acquired in-process research and development



                                       11
<PAGE>   12


projects included additional coding, cross-platform porting and validation,
quality assurance procedures and beta testing. The estimated future cost of
completing these activities was expected to be approximately $1 million to be
incurred over the next 12 months. Revenue streams from the resulting products
are expected to begin in fiscal 2000 and were projected forward for five years
in the risk adjusted income analysis. This allocation resulted in a $1,155,000
charge, net of taxes, to the Company's operations in fiscal year 1998. The
remaining purchase price was allocated, based on appraisals, to software
($3,113,643), net tangible assets ($324,428), and deferred tax assets
($595,000).

In connection with the review of its portfolio of intangible assets during
fiscal 1998, the Company wrote off certain items as a result of re-examining
its human resource allocation, product development plans and infrastructure
requirements. Previously capitalized third party product development costs
totaling approximately $1.3 million were written off in line with the Company's
strategy to narrow its product development focus. Previously capitalized third
party development costs of approximately $1.5 million associated with
inefficient, stand alone system configuration software were written off as the
Company's new management information systems (see Note B) have enabled it to
develop and integrate system configuration capabilities which, previously, were
addressed by the stand alone system.

NOTE D - ACCOUNTS PAYABLE AND ACCRUED EXPENSES

Accounts payable and accrued expenses consist of the following at February 28:

NOTE E - REVOLVING CREDIT AGREEMENT

The Company has an unsecured revolving credit agreement with Bank of America in
the amount of $20,000,000 which expires November 18, 2001. At February 28, 1999
and 1998, the Company had borrowed $5,000,000 and $9,000,000, respectively,
under the agreement at an average annual interest rate of 5.8% and 8.5%,
respectively. Interest under the credit arrangement accrues at a variable rate
indexed to the prime rate or an adjusted LIBOR rate. The fair value of this
debt approximates its carrying value at February 28, 1999 and 1998.

RESTRICTED STOCK PLAN

During fiscal 1996, the Company adopted a Restricted Stock Plan under which an
aggregate of 1,000,000 shares may be issued. 184,570 shares have been allocated
to three senior executives to be earned based on the achievement of certain
targeted share prices and the continued service of each executive for a
two-year period after each target is met. The remaining shares are available
for annual grants to other key executives as a component of their annual
bonuses on the achievement of targeted annual earnings per share objectives and
the completion of an additional two years of service after the grant. Activity
related to restricted stock during fiscal 1999, 1998 and 1997 is as follows:

The weighted average share price for grants during fiscal year 1997 was $10.64
for the Senior Executive Plan and $14.72 for the Key Executive Plan. Shares
forfeited in fiscal 1998 and 1997 had been granted at a weighted average share
price of $11.17 and $10.90, respectively. There was no activity for this plan
during fiscal 1999. At February 28, 1999, approximately 857,086 shares are
reserved for future restricted stock grants.

OTHER STOCK AWARD PLAN DISCLOSURES

Because the Company has elected to continue to apply the provisions of APB 25
for expense recognition purposes, Statement of Financial Accounting Standards
No. 123, "Accounting for Stock-Based Compensation", ("FAS 123") requires
disclosure of pro forma information which provides the effects on Net income
and Net Income per share as if the Company had accounted for its employee stock
awards under fair value methods prescribed by FAS 123. The fair value of the
Company's employee stock awards was estimated using a Black-Scholes option
pricing model with the following weighted-average assumptions for fiscal 1999,
1998 and 1997, respectively: risk-free interest rates of 5.38%, 6.48% and
6.39%; stock price volatility factors of .75, .49 and .66; and expected option
lives of 3.52 years, 4.3 years and 4.1 years. The Company does not have a
history of paying dividends, and none have been assumed in estimating the fair
value of the options. The weighted-average fair value per share of options
granted in fiscal 1999, 1998 and 1997 was 3.26, 1.98 and 5.91, respectively.

</TABLE>

As required by FAS 123, only awards granted after fiscal 1995 have been
included in determining the amount of additional compensation expense for those
years. As such, the effects of applying FAS 123 on fiscal 1999, 1998 and 1997
results are not necessarily representative of the additional compensation
expense which will be included in future years' pro forma disclosures as more
than two years of awards will be considered.

PREFERRED SHARE PURCHASE RIGHTS

One Preferred Share Purchase Right is attached to each outstanding share of the
Company's common stock. The rights will become exercisable upon the earlier to
occur of ten days after the first public announcement that a person or group has
acquired beneficial ownership of 20 percent or more, or ten days after a person
or group announces a tender offer that would result in beneficial ownership of
20 percent or more of the Company's outstanding common stock, the rights become
exercisable and each right will entitle its holder to purchase one
eight-hundredth of a share of Series A Preferred Stock for $37.50, subject to
adjustment. If the Company is acquired in a business combination transaction
while the



                                       16

<PAGE>   17

rights are outstanding, each right will entitle its holder to purchase, for
$37.50, common shares of the acquiring company having a market value of $75. In
addition, if a person or group acquires beneficial ownership of 20 percent or
more of the Company's outstanding common stock, each right will entitle its
holder (other than such person or members of such group) to purchase, for
$37.50, a number of shares of the Company's common stock having a market value
of $75. Furthermore, at any time after a person or group acquires beneficial
ownership of 20 percent or more (but less than 50 percent) of the Company's
outstanding common stock, the Board of Directors may, at its option, exchange
part or all of the rights (other than rights held by the acquiring person or
group) for shares of the Company's common stock on a one-for-one basis. At any
time prior to the acquisition of such a 20 percent position, the Company can
redeem each right for $0.00125. The Board of Directors is also authorized to
reduce the 20 percent thresholds referred to above to not less than 10 percent.
The rights expire in the year 2001.


NOTE H - TREASURY STOCK

Pursuant to authorizations by the Company's Board of Directors, the Company
repurchased 294,000 and 2,700,800 shares of its common stock during fiscal 1999
and 1998, respectively, at an average price per share of $19.97 and $9.70,
respectively. All shares held in treasury were reissued as a part of the
two-for-one stock split paid in the form of a stock dividend which took place
on January 11, 1999.

NOTE I - NON-RECURRING EXPENSES

During fiscal 1998, the Company incurred non-recurring expenses of
approximately $6.8 million including the following: $1.0 million associated
with certain personnel matters, including the resignation of the Company's
former President and Chief Operating Officer, $1.0 million to provide for
potential inventory obsolescence, and $3.0 million to write off certain
intangible assets (see Note B). Additionally, the Company wrote off as
in-process research and development approximately $1.8 million of the purchase
price paid to Integrated Telephony Products, Inc. for its ESP product line (see
Note C).

The Company incurred a one-time charge of approximately $1.8 million in
connection with the settlement of certain litigation during fiscal 1997.

Options to purchase 633,098, 3,725,712, and 2,290,138 shares of common stock at
average exercise prices of $10.77, $7.10, and $10.90, respectively, were
outstanding at February 28, 1999, 1998, and 1997, respectively, but were not
included in the computations of diluted earnings (loss) per share because the
effect would have been anti-dilutive to the calculations. For 1999 and 1997,
the anti-dilution is due to options' exercise prices which were greater than
the average market prices of the common shares. For 1998, the anti-dilution is
due to the net loss for the year ended February 28, 1998.

NOTE K - OPERATING SEGMENT INFORMATION AND MAJOR CUSTOMERS

The Company has adopted Statement of Financial Accounting Standards (SFAS) No.
131, "Disclosures about Segments of an Enterprise and Related Information,"
which requires the reporting of certain financial information by operating
segment and geographic area. InterVoice is comprised of a single operating
segment which develops, sells and services call automation systems. The
Company's Chief Operating Decision Maker (CODM) assesses performance and
allocates resources on an enterprise-wide basis. Therefore, no separately
reportable operating segments exist.

The CODM monitors revenues based on customer markets, including Customer Premise
Equipment (CPE), Telecommunications (Telco) and geographic area. The CPE market
includes interactive voice response and customer relationship management systems
such as the Company's OneVoice and AgentConnect products. The Telco customer
market focuses on systems for telecommunications network operators and includes
the Company's InControl product. CPE and Telco revenues are shown exclusive of
system maintenance and software license fee revenues. The Company's net revenues
by customer market and geographic area were as follows (in thousands):

*Represent export sales from the United States

No customer accounted for 10% or more of the Company's sales during fiscal 1999
or 1998. One customer, Siemens AG, one of the Company's resellers, accounted
for 10.2% of the Company's sales during fiscal 1997.

NOTE L -  CONCENTRATIONS OF CREDIT RISK

The Company sells systems directly to end-users and distributors primarily in
the banking and financial, telecommunications, human resource, healthcare and
call center vertical markets. Credit is extended based on an evaluation of a
customer's financial condition and a deposit is generally required. The Company
has made a provision for credit losses in these financial statements, which
have been less than 1% of sales in the periods reported.

NOTE M - EMPLOYEE BENEFIT PLAN

The Company sponsors an employee savings plan which qualifies under section
401(k) of the Internal Revenue Code. All full time employees who have completed
three months of service are eligible to participate in the plan. The Company
matches 50% of employee contributions up to 6% of the employee's eligible
compensation. Company contributions totaled $798,000, $854,000, and $759,000 in
fiscal 1999, 1998 and 1997, respectively.

NOTE N - CONTINGENCIES

Commencing in fiscal 1997, Lucent Technologies ("Lucent") suggested in
correspondence to the Company that it should consider licensing certain Lucent
patents for a substantial payment. The Company has an opinion from its outside
legal counsel that the Company does not infringe the Lucent patents by reason of
non-infringement and/or invalidity. The Company has suggested to Lucent that
Lucent should consider licensing certain patents of the Company, and that a
mutual cross-license might be in the best interests of both parties. The parties
have discussed the possibility of negotiations for a mutually satisfactory
cross-license agreement which would resolve the matter. There is no assurance
that the Company will be able to negotiate a cross-license agreement based on
mutually satisfactory terms. Lucent has not threatened litigation against the
Company, and the Company and Lucent did not have any discussions or exchange any
correspondence concerning their respective patent portfolios during fiscal 1999.
In the event that litigation is instituted against the Company concerning the
Lucent patents, the Company intends to vigorously contest the claims and to
assert defenses of non-infringement and/or invalidity of the patents, together
with any other defenses and counterclaims, including any counterclaim for
infringement of its patents, the Company might have. As with any legal
proceeding, there is no guarantee that the Company will prevail in any
litigation asserted against the Company in connection with the Lucent patents.


NOTE O - SUBSEQUENT EVENT

On April 27, 1999, the Company signed a definitive merger agreement to acquire
all of the outstanding shares of Brite Voice Systems, Inc. (Brite). Pursuant to
the agreement, InterVoice will pay Brite shareholders $13.40 per Brite share,
or based on approximately 12.3 million shares of Brite common stock
outstanding, total consideration of approximately $164.4 million. Of this
total, approximately $122.7 million, or $10.00 per Brite share, will be in cash
and approximately $41.7 million, or $3.40 per Brite share, will be in shares of
InterVoice common stock. The merger will be accounted for as a purchase
business combination.

The transaction will be executed in two steps, the first being an all cash
tender offer at $13.40 per share for approximately 9.2 million shares of
Brite's common stock. The second step will consist of a merger in which shares
of Brite common stock not purchased in the cash tender offer will be exchanged
into shares of InterVoice common stock. The ratio of exchange will be
determined at the time of the merger based on the average closing price of an
InterVoice share for the preceding twenty-five trading days. This transaction
has been approved by the Boards of Directors of Brite and InterVoice. The cash
tender offer will close on June 1, 1999. The closing of the transaction is
subject to certain customary conditions as described in the merger agreement.

In connection with this transaction, InterVoice has received a commitment from
Bank of America to provide senior secured credit facilities amounting to $150
million, which will include a $125 million term loan facility and a $25 million
revolving credit agreement. The term loan agreement will be subject to scheduled
repayments, as defined, during 2000-2003. The revolving credit agreement will
expire upon the earlier of the termination of the term loan, or August 31, 2003.
