                        MELITA INTERNATIONAL CORPORATION
                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
                      (IN THOUSANDS EXCEPT PER SHARE DATA)
                                   (UNAUDITED)


1.  Basis of Presentation

The unaudited consolidated financial statements presented herein have been
prepared in accordance with generally accepted accounting principles applicable
to interim financial statements. Accordingly, they do not include all of the
information and notes required by generally accepted accounting principles for
complete financial statements. In the opinion of the Company's management, these
consolidated financial statements contain all adjustments (which comprise only
normal and recurring accruals) necessary to present fairly the financial
position as of March 31, 1998, the results of operations and changes in cash
flows for the three months ended March 31, 1998 and 1997. The interim results
for the three months ended March 31, 1998 are not necessarily indicative of the
results to be expected for the full year. These statements should be read in
conjunction with the Company's combined financial statements for the fiscal year
ended December 31, 1997, as filed in its annual report on form 10-K.

2.  Principles of Consolidation

The accompanying financial statements include the accounts of the Company and
its wholly-owned subsidiaries. All significant inter-company balances and
transactions have been eliminated in consolidation.

3.  Completion of Initial Public Offering and Combination

On June 4, 1997, the Company completed its initial public offering ("IPO") of
common stock. The Company sold 4,025 shares of common stock, including the
underwriters' over-allotment of 525 shares, for $40,250 less issuance costs of
$4,148. Concurrently with the IPO, the Company issued 3,143 shares in connection
with the combination of Melita International, Melita Europe Limited and
Inventions, Inc.

4.    Inventories

Inventories are stated at the lower of first-in, first-out (FIFO) cost or market
and consist of the following at:

5.  Earnings Per Share

Earnings per share are computed using the weighted-average number of common
stock and dilutive common stock equivalents ("CSE") shares from stock options
(using the treasury stock method) outstanding during each period. Also included
are (1) common stock and CSE's issued at a price below the initial public
offering price during the 12 month period prior to June 4, 1997, and (2) CSE's
in an amount necessary to pay the stockholder distributions.

6.  Income Taxes

In connection with the IPO the Company converted from an "S" corporation to a
"C" corporation and, accordingly, is subject to federal and state income taxes.
Upon the conversion, the Company recognized a one-time benefit by recording the
asset related to the future reduction of income tax payments due to timing
differences between the recognition of income for financial statements and
income tax regulations. Pro forma income tax provisions reflect the Company's
anticipated effective annual tax rate of 38.0% for 1997.

7.  Earnings Per Share

During the first quarter of 1997, the Financial Accounting Standards Board
("FASB") issued Statement of Financial Accounting Standards No. 128, "Earnings
Per Share" ("SFAS No. 128"). This standard is effective for fiscal years ending
after December 15, 1997. The prior years' earnings per share have been
retroactively restated in accordance with this statement.

8.    Revenue Recognition

In October, 1997 the American Institute of Certified Public Accountants issued
SOP 97-2, Software Revenue Recognition. The Company believes that its revenue
recognition practices are consistent with those required by SOP 97-2.

9.    Other Comprehensive Income

In June, 1997 the FASB issued SFAS No. 130, "Reporting Comprehensive Income".
SFAS No. 130 establishes standards for the disclosure of all components of
comprehensive income. Comprehensive income is defined as the change in equity of
a business enterprise during a period from transactions and other events and
circumstances from non-owner sources. The Company adopted SFAS No. 130 in 1998.
The changes in the components of other comprehensive income are reported as
follows (in thousands):

10.   Recently Issued Accounting Standards

In June, 1997 the FASB issued SFAS No. 131, "Disclosures About Segments of an
Enterprise and Related Information". SFAS No. 131 requires certain financial and
supplementary information to be disclosed on an annual and interim basis for
each reportable segment of an enterprise. SFAS No. 131 is effective for fiscal
years beginning after December 15, 1997 and is not required in interim financial
statements in the initial year of application.



ITEM 2.   Management's Discussion and Analysis of Financial Condition and 
          Results of Operations

Results of Operations

Three Months Ended March 31, 1998 and 1997

Total revenues of $20.4 million in the first quarter of 1998 increased 38.9% as
compared to the same period in 1997. Product revenue increased $4.5 million or
44.4% to $14.8 million for the first quarter of 1998 as compared to the first
quarter of 1997. Service revenue increased $1.2 million or 26.1% to $5.6 million
in the first quarter as compared to the same quarter in 1997. The growth in
product revenues was due to continued increasing demand for the Company's
products, increased marketing and sales efforts, and the further penetration
into the telemarketing arena. Service revenues increased during the quarter due
to the continued expansion of the Company's installed customer base and the
increased volume of installations during the period.

Cost of product revenue, as a percentage of product revenue, decreased 5.3
percentage points for the first quarter of 1998 as compared to 1997. Product
cost as a percentage of product revenue decreased during the first quarter
principally due to the continuing engineering product cost reduction efforts and
an increase in the volume of shipments as compared to fixed costs. Cost of
service revenue increased 6.4 percentage points for the three months ended March
31, 1998 due to an increase in support service personnel and increases in
compensation.

Research and development cost was $2.3 million in the first quarter of fiscal
1998, a $914,000 increase over the first quarter of 1997. The overall cost
increase during the first quarter resulted primarily from the addition of
developers to support the Company's new product development efforts and the
subcontracting of certain feature development efforts during 1998.

Selling, general and administrative expenses were $6.8 million for the first
quarter of 1998 as compared to $5.1 million in the comparable 1997 period. This
increase was the result of an increase in sales commissions corresponding to the
increase in revenues, the additional staff required to support the larger sales
levels in 1998, and an increase in advertising and trade show activities.
Selling, general and administrative expenses decreased as a percentage of
revenue to 33.5% from 35.0% for the first quarter of fiscal 1998.

Income from operations was $3.7 million in the first quarter of 1998,
representing a 55.3% increase over income from operations of $2.4 million in the
first quarter of 1997. These increases were the result of the foregoing factors.

Other income (expense), net was a net income of $273,000 in the first quarter of
1998 compared to net expense of $51,000 in the first quarter of 1997. The
increase in other income reflects the earnings from the higher average cash and
short term investment balances in 1998 as compared to 1997.

<PAGE>   9




Income tax provisions have been recorded for the period subsequent to the IPO.
The Company prior to the IPO was not subject to federal or state income taxes.
As a result of its election to be treated as an "S" Corporation for income tax
purposes prior to the IPO, pro forma net income amounts include additional
provisions for income taxes determined by applying the Company's anticipated
statutory tax rate to income before income taxes, adjusted for permanent tax
differences. The Company's "S" Corporation status was terminated in conjunction
with the completion of its initial public offering in June 1997. Upon the
termination of its "S" Corporation election, the Company recorded certain
deferred tax assets in the amount of $1.5 million. The Company's pro forma
income tax rate was 36.0% in the first quarter of 1998 compared to 38.6% in the
first quarter of 1997, primarily due to the impact on operations of a foreign
sales corporation.

Pro forma net income increased to $2.5 million in the first quarter of 1998 from
$1.4 million in the first quarter of 1997, as a result of the operational, other
income and tax factors described above.

LIQUIDITY AND CAPITAL RESOURCES

In June 1997, the Company completed its IPO, in which the Company received net
proceeds of approximately $36.1 million after deducting underwriting discounts
and offering expenses. The Company applied a portion of the net proceeds to (1)
repay outstanding stockholder notes of $15.2 million, (2) payment of $245,000 in
accrued interest on the stockholder notes, and (3) pay undistributed "S"
Corporation earnings of $ 2.4 million. Prior to the IPO date, the Company made
payments of $375,000 to repay stockholder notes, and $3.6 million in
distributions to stockholders. The balance of the net proceeds of the offering
(approximately $18.3 million) will be utilized for general corporate purposes.
Such purposes may also include possible acquisitions of, or investments in,
businesses and technologies that are complementary to those of the Company. The
Company has no specific agreements, commitments or understandings with respect
to any such acquisitions or investments.

As of March 31, 1998, the Company had $28.9 million in cash, cash equivalents
and marketable securities, compared to $30.8 million as of December 31, 1997.
The Company's working capital was $34.0 million for the period ending March 31,
1998 as compared to $32.3 million for period ending December 31, 1997. Operating
activities used $715,000 during the first three months of fiscal 1998. Cash used
in investing activities totaled $213,000 million during the first three months
of fiscal 1998. Such investing activities consisted of purchases of property and
equipment and a decrease in short term interest bearing investments. The Company
anticipates that existing cash and cash equivalents will be adequate to meet its
cash requirements for the next twelve months.
