required to be filed by Section 13 or 15(d) of the Securities Exchange Act of

incorporated by reference in Part III of this Form 10-K or any amendment to this
Form 10-K.

  As of March 29, 1999, the aggregate market value of the common stock of NOVA
held by non-affiliates of the Registrant was approximately $1,516,636,817 based
upon the closing price of $25.750 per share on the New York Stock Exchange on
such date. Non-affiliate ownership is calculated by excluding all shares that
may be deemed to be beneficially owned by executive officers, directors and
other control persons, without conceding that all such persons are "affiliates"
for purposes of the federal securities laws. As of March 29, 1999, there were
72,819,789 shares of the Registrant's common stock outstanding.

Forward-looking Statements
  In addition to historical information, this Annual Report on Form 10-K
contains "forward-looking statements" within the meaning of Section 27A of the
Securities Act of 1933 (the "Securities Act"), as amended, and Section 21E of
the Securities and Exchange Act of 1934, as amended (the "Exchange Act"). When
used in this report, the words "may," "could," "should," "would," "believe,"
"anticipate," "estimate," "expect," "intend," "plan" and similar expressions or
statements regarding future periods are intended to identify forward-looking
statements. All forward-looking statements are inherently uncertain as they are
based on various expectations and assumptions concerning future events, which by
their nature involve substantial risks and uncertainties beyond NOVA
Corporation's control. Forward-looking statements may also be made in NOVA's
other reports filed under the Exchange Act, press releases, and other documents;
as well as by NOVA management in oral statements. NOVA undertakes no obligation
to update or revise any forward-looking statements for events or circumstances
after the date on which such statement is made. New factors emerge from time to
time, and it is not possible for NOVA to predict all of such factors. Further,
NOVA cannot assess the impact of each such factor on its business or the extent
to which any factor, or combination of factors, may cause actual results to
differ materially from those contained in any forward-looking statements.

NOVA's forward-looking statements are based upon numerous assumptions, including
assumptions relating to:

 .  Continued growth in the level in transaction volume;
 .  The impact of acquisitions (including without limitation the acquisition of
   PMT Services, Inc.), portfolio purchases, joint ventures and other alliances;
 .  Consolidation activity in the banking and transaction processing industries;
 .  Pricing strategies and market concentration considerations;
 .  Strategies relating to new technologies and product development;
 .  Changes in credit card association rules, laws, regulations, or other
   industry standards;
 .  General economic conditions and industry trends; and
 .  The impact of NOVA's Year 2000 compliance efforts as well as those of NOVA's
   vendors, supplies and customers

Readers are cautioned not to place undue reliance on these forward-looking
statements, which reflect management's opinion as of the date of this report.
NOVA refers readers to the information set forth under the caption "Item 1.
Business--Certain Risks Associated with the Business of the Company" included in
this Annual Report on Form 10-K, as well as "Item 7. Management's Discussion and
Analysis of Financial Condition and Results of Operations" contained herein, for
a more complete discussion of certain risk factors.

</TABLE>

  The Company has never paid cash dividends on its Common Stock.  The Board of
Directors' policy is to retain any available earnings for use in the operation
and expansion of the Company's business.  Therefore, no payment of cash
dividends is likely in the foreseeable future.  The Company's loan agreement
restricts the payment of dividends.  See Note 8 of the accompanying Consolidated
Financial Statements.     


RECENT SALES OF UNREGISTERED SECURITIES

  In January 1998, NOVA granted Kessler Financial Services, L.P. ("Kessler")
warrants to purchase 50,000 shares of common stock of NOVA (the "Kessler
Warrants"). The Kessler Warrants were granted as consideration for Kessler
providing to NOVA certain marketing and referral services pursuant to a
marketing agreement. The transaction was effected in reliance upon the exemption
from registration set forth in Section 4(2) of the Securities Act.

ITEM 7.  MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND
         RESULTS OF OPERATION

          MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION
                           AND RESULTS OF OPERATIONS

OVERVIEW

    
  Since the incorporation of NOVA's predecessor, NOVA Information Systems, in
February 1991, NOVA Corporation has grown in dollar volume processed to become
one of the five largest integrated transaction processor in the United States,
leading to significant increases in revenues and improved operating
efficiencies. This growth has been fueled by NOVA's marketing programs and
through a series of strategic merchant portfolio purchases and acquisitions,
joint venture agreements, and long-term banking alliances that provide a channel
for merchant portfolio purchases, as well as long-term exclusive marketing
arrangements.      

  NOVA's portfolio purchases, joint venture investments, and marketing alliances
provide significant strategic and financial benefits including: (1) enhanced
distribution channels to facilitate growth in transaction volume, (2) expansion
of the number of merchant locations served, (3) further geographic
diversification of NOVA's portfolio, and (4) economies of scale derived from
substantial increases in transaction processing volume.

  The PMT Merger enables NOVA to integrate two unique sales channels, while
leveraging NOVA's existing in-house technologies of NOVA. Following the PMT
Merger, NOVA has continued to focus on the processing sector comprised primarily
of small- to medium-sized merchants, who historically have been overlooked and
could benefit from the advantages of value-added services usually offered only
to large merchants. The ISOs that operate as subsidiaries of PMT provide an
existing customer pipeline for processing over the NOVA Network and NOVA's
sophisticated client/server platforms. From its origin, NOVA has invested
significant capital to develop, expand and enhance an integrated technology
platform of hardware, software applications and network architecture to process
large volumes of transactions.

  Concurrent with the PMT Merger in the third quarter of 1998, NOVA recorded
transaction costs of $15.5 million. During the fourth quarter of 1998, as the
plans for the integration and consolidation of PMT were finalized, NOVA
recognized an additional $75.2 million as the cost of implementing these plans.
In December 1998, NOVA announced its plan to accelerate the conversion and
integration of PMT's customer base from existing third-party providers to the
NOVA Network.  Although this strategy will result in increased costs in 1999,
management believes it will benefit NOVA's long-term performance by improving
customer service and decreasing merchant attrition, and accelerating the
elimination of redundant selling, general and administrative functions of the
two companies. Management continues to examine and evaluate the operational
efficiencies which may result from the PMT Merger in order to leverage NOVA's
financial position and focus on its strengths in business lines, products and
services, as well as market share.

  In January 1998, NOVA and KeyBank completed a transaction pursuant to which
KeyBank contributed merchant contracts to KMS. Pursuant to this agreement, NOVA
provides transaction processing services to the merchant customers of KMS and is
responsible for its operation and management.  NOVA owns a 51% controlling
interest in KMS.  During 1998, KMS contributed processed volume in excess of
$5.3 billion to NOVA's operating platform. In addition to KMS's direct sales
force, KeyBank exclusively markets and promotes NOVA's transaction processing
services on behalf of KMS through KeyBank's bank branch locations.  In
connection with the formation of KMS, NOVA began the consolidation and
conversion of the existing merchant processing to NOVA's operating platforms.
Associated with this process and concurrent with consummating the transaction,
NOVA recognized a non-recurring charge of $2.0 million to account for the early
termination of a contract with a third party processor.
    
  In October 1997, NOVA consummated the Elan joint venture with Firstar whereby
Firstar contributed substantially all of its then existing merchant bankcard
processing portfolio to Elan. Pursuant to the Elan joint venture, NOVA provides
transaction processing services to the merchant customers of Elan and is
responsible for its operation and management. NOVA owns a 51% controlling
interest in the Elan joint venture. During 1998, Elan contributed processed
volume in excess of $3.0 billion to NOVA's operating platforms. Firstar markets
and promotes, on an exclusive basis, the merchant transaction processing
services of NOVA on behalf of Elan through a network of correspondent financial
institutions.

  Integral to NOVA's significant revenue expansion has been the selective
purchases of merchant processing portfolios.  Most notable in 1998 was the
October 1998 purchase of the merchant processing portfolio of FUBD, successor by
merger to CoreStates Bank.

  The CoreStates portfolio added geographical diversity and strength to NOVA's
merchant customer base through the portfolio's approximate $3.1 billion in
annual processing volume.

  On December 31, 1997, NOVA purchased substantially all of MBNA's merchant
portfolio. MBNA also agreed to market the merchant processing services of NOVA
through an exclusive referral arrangement for all merchants, trade associations,
financial institutions, ISOs, and other organizations that express to MBNA an
interest in merchant processing services. The MBNA portfolio contributed
approximately $1.1 billion in annualized credit and debit card processing volume
in 1998.

  Prior to the PMT Merger and since fiscal 1997, PMT completed three significant
merger transactions with ISOs: Superior Bankcard Service, Inc. ("Superior") in
July 1998, MBN National, Inc. ("MBN") in May 1998, and Bancard, Inc. ("BCI") in
October 1997. PMT previously accounted for each of these acquisitions as a
pooling of interests transaction. Accordingly, all years presented have been
restated to reflect the operations of each entity. 


<PAGE>
 
Revenues recognized during 1998 for the Superior, MBN and BCI operations were
$31.7 million, $15.3 million and $76.9 million, respectively.

  Historically, NOVA has achieved savings through economies of scale and
operating efficiencies derived from the conversion and integration of its
purchased portfolios.  The costs of these conversion activities are expensed as
incurred. As a result of the PMT Merger, the magnitude, scope, timing, duration
and expense of conversion and consolidation will, in the aggregate, be
significant. Failure to complete the conversion and consolidation in accordance
with management plans could have a material adverse effect on NOVA's financial
condition and results of operations.

COMPONENTS OF REVENUES AND EXPENSES

                                   REVENUES
                                        
  NOVA derives revenues principally from electronic processing of credit, charge
and debit card transactions that are authorized and captured through the NOVA
Network and through third-party networks prior to conversion.  Typically
merchants are charged for these processing services at a bundled rate that is a
percentage of the dollar amount of each transaction and, in some instances,
additional fees per transaction.  These charges, referred to as "merchant
discount", are negotiated with each merchant and, in the aggregate, represent in
excess of 90% of NOVA's revenues.  Certain merchant customers are charged a flat
fee per transaction, while others may also be charged miscellaneous fees,
including fees for handling chargebacks, monthly minimums, equipment rentals,
sales or leasing, and other miscellaneous services.   Revenues are reported net
of amounts paid to ISOs, agent banks and merchant associations under revenue
sharing agreements pursuant to which such parties receive payments based
primarily on processing volume for particular groups of merchants.

EXPENSES

  Cost of service includes costs directly attributable to the furnishing of
transaction processing and other services to NOVA's merchant customers.  The
most significant components of cost of service include interchange and
assessment fees, which are charged by the credit card associations for clearing
services, advertising and other expenses.  Interchange and assessment fees are
billed primarily as a percent of dollar volume processed and, to a  lesser
extent, as a per-transaction fee. Cost of service also includes charges paid to
third parties for POS network service (for merchant customers acquired but not
yet converted to the NOVA Network), merchant accounting and settlement fees,
cost of equipment leased, rented or sold, NOVA Network costs and other direct
operating expenses.

  Conversion costs include expenses incurred to convert acquired portfolios from
existing processing platforms to the NOVA Network and operating systems. Such
costs are expensed as incurred and these costs include expenses related to
reprogramming POS terminals at merchant locations, duplicate costs to process
transactions prior to conversion, unfavorable contract payments for transaction
authorizations, and independent contractor fees.

  Selling, general and administrative expenses include salaries and wages,
commissions, employee benefits, travel and entertainment, telecommunications,
and other costs of the operations and marketing centers, subsidiary offices, and
corporate headquarters.  Depreciation and amortization costs are related to
NOVA's capital expenditures, merchant portfolio purchases and business
acquisitions.

YEAR ENDED DECEMBER 31, 1998, COMPARED WITH YEAR ENDED DECEMBER 31, 1997

                                   REVENUES
                                        
     NOVA's revenue increased $464.8 million, or 68.3%, to $1.1 billion for the
year ended December 31, 1998, compared with $680.9 million for the same period
in 1997. This revenue growth is primarily attributable to a 61.7% increase in
merchant sales processing volume to $47.5 billion from $29.4 billion in 1997. Of
the total increase, approximately $8.1 billion in volume and $195.8 million in
revenues are attributable to the Elan and KMS joint ventures. Other purchases,
in the aggregate, contributed approximately $4.7 billion in volume and $109.2
million in revenues over 1997 levels. The pass-through of higher interchange
rates from the credit card associations in the form of higher discount rates
accounts for approximately $40.0 million of the increased revenues. The
remaining increase is primarily due to internal growth and bank marketing
relationships.

COST OF SERVICE

     Cost of service increased $366.2 million, or 70.5%, to $885.6 million for
the year ended December 31, 1998, from $519.4 million for the same period in
1997. The increase resulted from additional interchange and assessment fees and
other operating costs associated with the higher merchant sales volume
processed. Incremental increases were also recognized for interchange expenses
as a result of credit card association rate increases. Cost of service as


                                      29
<PAGE>
 
a percentage of revenue increased to 77.3% from 76.3% because a substantial
portion of the volume from recent portfolio purchases and joint venture
transactions has not been converted to the NOVA Network and therefore is being
processed by third party vendors at a higher cost.

CONVERSION COSTS
    
     Conversion costs increased $7.4 million over 1997 levels to $10.0 million
in 1998. This increase relates to the increased conversion efforts in 1998 as
compared to 1997, including the conversions the KMS and Elan joint ventures, and
the MBNA and CoreStates merchant portfolios. Conversion activity for 1999 is
expected to exceed 1998 levels due to the magnitude of the conversion of PMT's
portfolios.     

SELLING, GENERAL AND ADMINISTRATIVE EXPENSES

     Selling, general and administrative expenses were $120.2 million in 1998,
an increase of $44.1 million, or 58.0%, over 1997 expenditures of $76.0 million.
Included in this expense classification are approximately $14.2 million in
unusual charges recorded in the fourth quarter associated with the PMT Merger.
Such charges primarily result from changes in management estimates pertaining to
collectibility of accounts receivable ($6.2 million), merchant credit and fraud
loss reserves ($4.7 million), and state sales and use tax reserves ($2.0
million), particularly in light of the possible effects that consolidation
activities may have.

     After consideration of these charges, other selling, general and
administrative expense's increased 39.3%. These increases are attributable to
(i) the costs paid to sellers for operating and managing merchant portfolios
during transition and conversion of the portfolios to the NOVA Network and (ii)
an expanded sales force associated with marketing arrangements entered into, in
each case, in conjunction with recent portfolio purchases and joint venture
transactions. In addition, during the third and fourth quarters of 1998, NOVA
incurred additional personnel and facilities costs in anticipation of beginning
the transition of all operational functions for the PMT merchant portfolios
beginning in October 1998. Many of these costs are duplicative of costs incurred
in connection with existing PMT operations that will be eliminated as part of
the integration of PMT onto the NOVA Network.

     Selling, general and administrative expenses as a percentage of revenue
decreased in 1998 to 10.5% from 11.2% in 1997.  Adjusted for the unusual costs
included in 1998, these expenses represented 9.2% of revenues, illustrating the
significant economies of scale resulting from NOVA's growth.

DEPRECIATION AND AMORTIZATION

     Depreciation and amortization expenses increased 90.0% to $44.8 million in
1998 compared to $23.6 million in 1997 due primarily to amortization expenses
associated with recent portfolio purchases and investments in joint ventures.

MERGER AND CONSOLIDATION EXPENSES

     As a result of the PMT Merger and other acquisitions completed by PMT
during 1998, NOVA recorded a $90.7 million charge in 1998. This charge was
primarily related to direct transaction costs, charges associated with the
consolidation and closure of PMT's corporate headquarters and certain operating
subsidiaries, contract termination costs related to unfavorable third party
processing contracts, and the decision to exit certain of PMT's sales
distribution channels.

     Direct merger transaction costs are primarily for investment banking
commissions, professional fees, and regulatory filing expenses.

     The primary costs associated with the consolidation and closure of
facilities include employee and executive severance, estimated unrecoverable
future lease obligations on vacated facilities, and the write-down of capital
assets to their net realizable value. The consolidation and closure actions
result from the elimination of overlapping functions, primarily customer
service, accounting, and administrative areas. The total number of employees
terminated was approximately 275, with 210 having received severance packages as
of December 31, 1998. The remaining employees will leave NOVA during the first
quarter of 1999. NOVA began the process of moving PMT's

                                      30
<PAGE>
 
operations located in Nashville, Tennessee to other locations in December 1998,
and expects the process to be completed in the first quarter of 1999, at which
time the premises in Nashville will be completely vacated.

     Consistent with past practice, management developed a plan in 1998 to
convert the front-end and back-end transaction processing of PMT's merchants to
the NOVA Network. As a result of this action, NOVA negotiated the termination of
certain long-term processing contracts between PMT and third-party processors
which resulted in early termination fees. The majority of these terminations
were finalized and paid in 1998. NOVA expects to complete the negotiation and
payment of the remaining contracts during the first half of 1999.

     Capital asset write-downs are substantially attributable to the computer
software and equipment, including PMT's management information and financial
reporting systems which were abandoned in December 1998. Additional assets
written down include telephone systems, and office furniture and equipment that
will not be redeployed for use at another NOVA facility.

     In 1998 management formulated plans to exit unique distribution channels
based upon the type of merchant business generated through these channels.
Specifically, servicing and maintaining the type of merchant generated through
these channels is not compatible with NOVA's operating philosophy and not
strategically aligned with NOVA's plan of business. The charge related to
exiting this distribution channel includes a contract termination fee and the
write-down of certain related intangible assets resulting from an analysis of
discounted future cash flows generated from the subject merchants.

     The majority of these costs were paid in the fourth quarter of 1998 and the
Company expects the plans associated with the remaining costs to be
substantially complete during the first half of 1999. Details of merger related
charges, including charges relating to the PMT merger are as follows:

OPERATING LOSS

     NOVA's consolidated operating loss for 1998 was $5.6 million, as compared
to operating income of $57.4 million during 1997. The loss in 1998 includes non-
recurring merger and consolidation charges of $90.7 million and $14.2 million in
unusual selling, general and administrative costs. The 1997 operating income
included a $1.9 million merger related charge incurred by PMT. Absent the merger
and consolidation charges and unusual costs, operating income would have been
$99.3 million in 1998 compared to $59.2 million in 1997, an increase of $40.1
million, or 67.7%, due to the factors noted above.

INTEREST INCOME AND EXPENSE

     Interest income increased 4.8% to $6.6 million in 1998, compared to $6.3
million in 1997. NOVA had higher average cash balances during 1998 due to a
public offering of common stock in April 1998 that yielded net proceeds of
$142.6 million.

     Interest expense increased 36.4% to $6.0 million in 1998, compared to $4.4
million in 1997, due to higher average debt obligations outstanding in 1998.
Average borrowings increased due to draws against NOVA's bank credit facility in
late 1997 and early 1998 to fund the Elan and KMS investments and the MBNA
portfolio purchase. In addition, NOVA recorded deferred purchase obligations in
January 1998 related to the KMS investment. Although all bank borrowings were
repaid during the second quarter using a portion of the offering proceeds, NOVA
continued to incur interest expense throughout the year related to the deferred
purchase obligation.

MINORITY INTEREST IN INCOME OF SUBSIDIARIES
    
     Minority interest in income of subsidiaries increased to $10.1 million in
1998 from $776,000 in 1997. This increase reflects the ten-month incremental
inclusion of Elan and approximately eleven months incremental inclusion of KMS.
     
INCOME TAXES

     NOVA's effective tax rate for 1998 was approximately 15.6%, compared with
an effective income tax rate of 35.2% for 1997. The decrease in the effective
rate primarily reflects the impact of the non-deductible portion of the merger
costs incurred in connection with the PMT Merger. Excluding the effect of the
non-deductible charges and the effect of Subchapter S corporation income which
is not subject to income tax, the effective tax rate for 1998 would be 40.4%.
The increase from the 1997 comparable rate of 38.2% is due to an increase in
state tax rates.

NET LOSS

     A net loss of $12.8 million, or $0.18 per share, in 1998 compares to net
income in 1997 of $37.9 million, or $0.58 per share.  Excluding both years'
merger related charges and the unusual selling, general and administrative
charges recognized during 1998, net income for 1998 of $57.9 million represented
an increase of approximately 45.5% over net income of $39.8 million in 1997 due
to the factors noted above.

YEAR ENDED DECEMBER 31, 1997 COMPARED WITH YEAR ENDED DECEMBER 31, 1996

REVENUES
    
     Revenues increased $160.5 million, or 30.8%, to $680.9 million for the year
ended December 31, 1997, compared to $520.4 million for the year ended December
31, 1996.  The increase resulted from a 29.7% growth in merchant sales volume
processed to $29.4 billion in 1997, compared to $22.7 billion in 1996.  Of these
increases, $1.5 billion in sales volume processed and $34.0 million in revenues
is attributable to the Elan joint venture and the Crestar portfolio purchase.
Other individually insignificant portfolio purchases, in the aggregate,
contributed approximately $3.7 billion in volume and $84.2 million in revenues
over 1997 levels. The remaining increase is primarily due to internal growth and
bank marketing relationships.

COST OF SERVICE

     Cost of service increased $119.3 million, or 29.8%, to $519.4 million for
the year ended December 31, 1997, from $400.1 million for the same period in
1996. Additional interchange and assessment fees and other direct operating
costs associated with the incremental increase in volume processed contributed
to the increase in expenses. Cost of service as a percentage of revenues
decreased slightly from 76.9% to 76.3%, reflecting cost efficiencies arising
from proportionately lower payments to third-party networks. This trend reflects
the substantial completion during 1996 of the conversion of the First Union
portfolio purchased in 1995, resulting in fewer merchant customers utilizing
external service providers during 1997 as compared to 1996.

CONVERSION COSTS

     Conversion costs decreased 59.4% to $2.6 million for 1997 compared with
$6.4 million for 1996. The decrease resulted primarily from the substantial
completion of the conversion of the First Union merchant portfolio in 1996.

SELLING, GENERAL AND ADMINISTRATIVE EXPENSES

     Selling, general and administrative expenses increased 11.7% to $76.0
million for the year ended 1997, compared with $68.1 million for the year ended
1996. Higher expenses in 1997 resulted from increased personnel support in
NOVA's primary operations center due to transaction volume growth. This growth
also accounts for the decrease in expenses as a percentage of revenue to 11.2%
in 1997 as compared to 13.1% in 1996.

DEPRECIATION AND AMORTIZATION

     Depreciation and amortization expenses increased 57.4% to $23.6 million in
1997 compared to $15.0 million in 1996. The principal component of this increase
was the incremental addition of amortization expense from merchant portfolio
purchases. Other factors contributing to this increase were significant capital
investments in the technology infrastructure to expand transaction processing
capacity.

INTEREST INCOME AND EXPENSE
    
     Interest income increased 85.3% to $6.3 million for fiscal year 1997,
compared with interest income of $3.4 million for fiscal year 1996. During 1996,
NOVA made three public offerings of stock and generated $206.3 million in net
proceeds. The offerings, which occurred primarily during the second and third
quarters of 1996, resulted in substantially higher average cash balances during
fiscal 1997, generating greater interest income.     

     Interest expense decreased 17.0% to $4.4 million in 1997 compared to $5.3
million in 1996. The favorable trend in interest expense is attributable to
using a portion of the 1996 offering proceeds to reduce outstanding debt.

INCOME TAXES

     NOVA's effective tax rate for 1997 was approximately 35.2%, compared with
an effective income tax rate of 36.3% for 1996. The decrease from the 1996
effective rate primarily reflects the impact of pooling transactions in 1997
with Subchapter S Corporations that are not subject to income tax.

NET INCOME

     Net income increased to $37.9 million, or $0.58 per share, in 1997 from net
income of $19.1 million, or $0.32 per share, in 1996, due to the factors
discussed above.

LIQUIDITY AND CAPITAL RESOURCES

     NOVA's primary uses of its capital resources include the purchase of
merchant portfolios, investments in joint ventures, capital expenditures and
working capital requirements. 

                                       33
<PAGE>
 
     
     NOVA produces significant cash flow from operating activities, amounting to
$37.8 million in 1998, $42.2 million in 1997, and $42.2 million in 1996.  Cash
flow is generated primarily from operating earnings, after considering the
effect of depreciation and amortization and, for 1998, the non-cash portion of
the merger and consolidation charges.  These cash flows are significantly
impacted by increases in trade receivables, primarily in 1998 and 1997, directly
attributable to the increases in processing volume and revenues.  During 1998,
deferred tax assets resulting from merger related timing differences also had a
significant unfavorable affect on cash flows from operating activities.
Investing activities utilized a net $108.0 million cash in 1998, compared to
$182.1 million in 1997, and $52.9 million in 1996. Significant 1998 investments
include $91.1 million for portfolio purchases, $46.4 million in enhancing and
improving the technology platforms and operating centers, and $27.9 million to
fund equipment leases. The nature of these uses is consistent with historical
uses.     

    
     Net cash provided by financing activities was $94.4 million, $15.9 million,
and $157.5 million for the years ended December 31, 1998, 1997, and 1996,
respectively. NOVA's financing sources during 1998 relate primarily to a stock
offering completed in April 1998, which provided $142.6 million, net of
expenses, and bank borrowings totaling $21.8 million.  Subsequent to the public
offering, NOVA used $53.1 million of the net proceeds to repay amounts
outstanding under its bank credit facilities.  Net cash provided in 1997
consists primarily of proceeds received from short-term and long-term debt
obligations, offset for cash outlays for the issuance of a note receivable of
$8.8 million.     

    
     NOVA has available a credit facility of $80.0 million which is expandable
to $100.0 million. At December 31, 1998, no borrowings were outstanding under
this facility. See Note 8 to the Consolidated Financial Statements. In
connection with the PMT Merger and other acquisitions closed in 1998 and 1999,
NOVA obtained a waiver of certain covenants under the credit facility, which is
effective for all applicable periods.     

    
     NOVA typically has relatively low working capital requirements because
merchant discount fees charged are collected in an average of 20 days, while
normal vendor payables are paid in 30 days or longer.  In addition, acquisition
activity may cause variations in working capital due to conversion period
operating costs and the transition in the payment of expenses and the collection
of receivables from the former processor to NOVA.  Because of the seasonality of
NOVA's business, capital requirements may be greater in certain months.     

     NOVA anticipates that it will incur approximately $25.0 million in capital
expenditures during 1999 for upgrading and expanding existing facilities and the
expansion and enhancement of its information systems.  Such investments are
generally attributable to the closure and consolidation of the PMT operations
and the migration of the PMT merchants to the NOVA Network.  Since electronic
transaction processing is virtually all technology based, NOVA expects to
continue the trend in capital investments in its technology infrastructure and
solutions for the foreseeable future.  However, there can be no assurances that
NOVA will not incur higher capital expenditures in 1999 and 2000 to support the
business.

     NOVA believes its existing cash and cash equivalents, cash generated from
operations, and available credit facilities are sufficient to fund future
merchant portfolio purchases, capital investment needs, and working capital
requirements for the foreseeable future.

YEAR 2000 COMPLIANCE

     The Year 2000 Issue is the result of date sensitive computer software
programs being written using two digits rather than four digits to define the
applicable year. Consequently, unless corrected, computer software programs will
be unable to read and accurately process date information on or after the year
2000. NOVA has critical reliance on technology systems, telecommunications
systems, facilities infrastructure and embedded systems, such as heating and
ventilation systems, in conducting its business. NOVA also has business
relationships with third party providers, such as telecommunication vendors,
financial institutions, and data processors, who are highly reliant on
information technology and other systems to conduct their business.

     Due to the significance of technology systems and other support systems, in
1997 NOVA launched its Year 2000 compliance efforts with a comprehensive
evaluation of its critical systems, applications, computing platforms, and
merchant terminals to ensure potential risks are identified and non-compliant
information systems upgraded or

                                       34
<PAGE>
 
replaced. The initial phase of the project was the identification of all
technology systems and determining which were at risk. After completion of this
phase, steps were taken to remediate and test those systems initially determined
to be non-compliant.

     In June 1997, VISA U.S.A. and Mastercard International certified NOVA as
capable of processing transactions for cards issued with expiration dates of
2000 and beyond. Also completed in 1997 was the validation and correction of
merchant terminals for Year 2000 functionality. In 1998, NOVA substantially
completed the review and correction of its identified systems. As an added
measure of validation, an independent review and evaluation was initiated for
the following: building infrastructure, client/server platforms, NOVA Network,
software applications, principal and strategic vendors' products or services,
and telecommunication platforms and equipment. NOVA believes that its Year 2000
project is on schedule and expects completion by mid 1999.

     Through 1998, NOVA has replaced or upgraded personal computers,
client/server applications, and certain computer software programs to be Year
2000 compliant. The nature of NOVA's business requires continuous development of
its technologies and systems, extensively utilizing internal resources in this
effort. Accordingly, it is difficult to determine with certainty the costs that
have been incurred to date, and costs expected to be incurred in the future to
support the Year 2000 effort.

     Despite NOVA's efforts, there cannot be absolute assurance that NOVA will
be completely successful in eliminating all business and operations risk. The
risks associated with the Year 2000 Issue include the possibility of a failure
of the information and non-information technology systems. System malfunction or
failure could result in incomplete or inaccurate transaction processing.
Additionally, NOVA may be adversely affected by a system malfunction or failure
of third parties that hold a business, financial or operational relationship
with NOVA; such as processing banks, telecommunication providers, and utilities.
If these third parties fail to adequately address Year 2000 issues, NOVA could
experience a negative impact on its business operations, such as business
interruption or shutdown. The consequences of interruption could cause NOVA to
suffer a material adverse impact on its financial condition and results of
operations.

     NOVA has begun to develop contingency and recovery plans as a precautionary
measure targeted at ensuring the continuation and continuity of critical
business functions before and after December 31, 1999.   NOVA will continue to
identify aspects of its business and that of its third-party providers and take
necessary corrective action, primarily the expedient replacement of any critical
vendor who does not provide proof of compliance.  The contingency efforts
described above are expected to minimize the business risk connected to the Year
2000 Issue.

ITEM 7A.  QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

     Interest Rates: NOVA is exposed to changes in interest rates due to
variable rate debt facilities. Based on the Company's debt profile at December
31, 1998, and 1997, a 1% increase in market interest rates would increase
interest expense and decrease income before income taxes by $744,000, and
$200,000, respectively. These amounts were determined by calculating the effect
of the hypothetical interest rate on our debt.

                        REPORT OF INDEPENDENT AUDITORS
                                        

The Board of Directors and Shareholders

     We have audited the accompanying consolidated balance sheets of NOVA
Corporation (and subsidiaries) as of December 31, 1998 and 1997, and the related
consolidated statements of operations, shareholders' equity, and cash flows for
each of the three years in the period ended December 31, 1998. Our audits also
included the financial statements schedule listed in the Index at Item 14(a).
These financial statements are the responsibility of the Company's management.
Our responsibility is to express an opinion on these financial statements based
on our audits. We did not audit the 1997 and 1996 financial statements or
schedule of PMT Services, Inc. ("PMT"), a wholly-owned subsidiary, and certain
of its subsidiaries which statements and schedule reflect total assets of 48%
and 40% as of December 31, 1997 and 1996, respectively, and total revenues of
45% and 43% for the years ended December 31, 1997 and 1996, respectively. Those
statements and schedule were audited by other auditors whose report has been
furnished to us, and our opinion, insofar as it relates to the 1997 and 1996
data included for PMT, is based solely on the report of the other auditors.

     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 and the report of other auditors
provide a reasonable basis for our opinion.

     In our opinion, based on our audits and the report of other auditors, the
consolidated financial statements referred to above present fairly, in all
material respects, the consolidated financial position of NOVA Corporation and
subsidiaries at December 31, 1998 and 1997, and the consolidated results of
operations and their cash flows for each of the three years in the period ended
December 31, 1998, in conformity with generally accepted accounting principles.
Also, in our opinion, based on our audits and the report of the other auditors,
the related financial statement schedule, when considered in relation to the
basic consolidated financial statements taken as a whole, presents fairly in all
material respects the information set forth therein.

To the Board of Directors
and Shareholders of PMT Services, Inc.

    
In our opinion, the consolidated balance sheet and the related consolidated
statements of income, of changes in shareholders' equity and of cash flows (not
presented separately herein) present fairly, in all material respects, the
financial position of PMT Services, Inc. and its subsidiaries at July 31, 1997
and 1996, and the results of their operations and their cash flows for the years
then ended in conformity with generally accepted accounting principles. These
financial statements are the responsibility of the Company's management; our
responsibility is to express an opinion on these financial statements based on
our audits. We conducted our audits of these statements in accordance with
generally accepted auditing standards which require that we plan and perform the
audit to obtain reasonable assurance about whether the financial statements are
free of material misstatement. An audit includes examining, on a test basis,
evidence supporting the amounts and disclosures in the financial statements,
assessing the accounting principles used and significant estimates made by
management, and evaluating the overall financial statement presentation. We
believe that our audits provide a reasonable basis for the opinion expressed
above.

                               NOVA CORPORATION
                  NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

                                    NOTE 1

                  SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

  DESCRIPTION OF BUSINESS AND ORGANIZATION.   NOVA Corporation (the "Company" or
"NOVA") is a provider of integrated electronic transaction processing services,
related software application products and value-added services primarily to
small-to-medium-sized merchants. The Company provides merchants with transaction
processing support for all major credit and charge cards, including VISA,
MasterCard, American Express, Discover, Diners Club and JCB, and also provides
access to debit card processing and check verification services. NOVA provides
merchants a broad range of transaction processing services, including
authorizing card transactions at the point-of-sale ("POS"), capturing and
transmitting transaction data, payment settlement, and assisting in resolving
billing disputes with customers.

  PRINCIPLES OF CONSOLIDATION.   The consolidated financial statements include
the accounts of NOVA Corporation and its majority-owned subsidiaries. All
significant intercompany transactions have been eliminated.

  COMBINED FINANCIAL RESULTS.   On September 24, 1998, NOVA completed a merger
transaction with PMT Services, Inc. ("PMT"), pursuant to which PMT became a
wholly-owned subsidiary of NOVA. In addition to the PMT merger, PMT completed
various mergers prior to the merger with NOVA. These mergers were intended to
qualify as tax-free reorganizations and were accounted for as poolings of
interests. Accordingly, the consolidated historical financial statements for all
periods presented combined the financial results of NOVA and PMT. Although prior
to the merger PMT reported on the fiscal year ended July 31 basis, PMT changed
their year end to October 31 in 1998. Conforming PMT to a calendar year fiscal
year was not practicable for 1998 due to the timing and cost associated with
establishing and auditing the beginning of year balances as of January 1, 1998.
Beginning in 1999, PMT's fiscal year will be changed to conform to a calendar
year.

  The NOVA balance sheet as of December 31, 1998, has been combined with the PMT
balance sheet as of October 31, 1998. The NOVA balance sheet as of December 31,
1997, has been combined with the PMT balance sheet as of July 31, 1997. The NOVA
statement of operations and cash flows for the year ended December 31, 1998, has
been combined with the PMT statement of  operations and cash flows for the
twelve months ended October 31, 1998. The NOVA statements of operations and cash
flows for the years ended December 31, 1997 and 1996, have been combined with
the PMT statements of operations and cash flows for the fiscal years ended July
31, 1997 and 1996. The results of operations of PMT for the period August 1,
1997 through October 31, 1997, of $7.6 million have been reported as an increase
to shareholders equity for the year ended December 31, 1998. Revenues for this
interim period were $101.1 million and expenses, including income taxes, were
$93.5 million.

  There were no transactions between NOVA and PMT prior to the combination, and
immaterial adjustments were recorded to conform PMT's accounting policies.
Certain reclassifications were made to the PMT financial statements to conform
to NOVA's presentations.

  USE OF ESTIMATES IN THE PREPARATION OF FINANCIAL STATEMENTS.  In preparing
financial statements in conformity with generally accepted accounting
principles, management is required to make estimates and assumptions that affect
the reported amounts of assets and liabilities and the disclosure of contingent
assets and liabilities at the date of the financial statements and revenues and
expenses during the reporting period. Actual results could differ from those
estimates.

  REVENUE AND COST OF SERVICE RECOGNITION.   Revenues derived principally from
the electronic processing of transactions (principally merchant discount) are
recognized, net of revenue sharing amounts, at the time the merchants'
transactions are processed. Directly related cost of service are also recognized
at the time of processing and include interchange fees paid to the credit card
issuing bank, VISA and MasterCard assessments, telecommunications expenses, and
merchant accounting processing fees.

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)
                                        
  When the Company purchases merchant portfolios, it typically enters into
revenue sharing agreements with the sellers. The revenue sharing amounts are
determined primarily on sales volume processed for a particular group of
merchants. The revenue sharing agreements generally have an initial term of at
least three years with renewal provisions. Revenue is shown in the accompanying
statements of operations net of revenue sharing amounts of $35.3 million, $16.3
million, and $15.3 million for the years ended December 31, 1998, 1997, and
1996, respectively.

  Additional revenue sources include the sale, lease and rental of POS
processing equipment. Revenues related to direct financing leases are recognized
over the term of the lease using the effective interest method. Equipment sales
revenues are recorded when the equipment is shipped. Rental income is recognized
as earned.

  CONVERSION COSTS.   The cost of converting purchased merchant portfolios from
the seller's processing platform and telecommunications network to the NOVA
Network is expensed as incurred.

  CASH AND CASH EQUIVALENTS.   For purposes of the consolidated statements of
cash flows, NOVA considers all highly liquid debt instruments with original
maturities of three months or less to be cash equivalents.

  RESTRICTED CASH.   Restricted cash represents funds held-on-deposit with
certain processing banks pursuant to agreements to cover potential merchant
losses, and funds held by lending institutions pursuant to loan agreements to
provide additional collateral. These amounts are classified as "Other Non-
current Assets" for financial statement purposes, and total $8.2 million and
$9.3 million at December 31, 1998 and 1997, respectively.

  INVESTMENTS.   The investments held at December 31, 1997, consist of United
States Government Treasury Notes that have a term of less than one year. These
investments are classified as held-to-maturity in accordance with Statement of
Financial Accounting Standards No.115, "Accounting for Certain Debt and Equity
Securities" ("SFAS 115"), and are carried at amortized cost as determined by
specific identification. The fair value of these investments was $49.2 million
at December 31, 1997. The Company held no investments at December 31, 1998.

  ACCOUNTS RECEIVABLE.   Accounts receivable are primarily comprised of amounts
due from the Company's clearing and settlement banks and represent the discount
earned, after related interchange fees on transactions processed during the
month ending on the balance sheet date. Such balances are received from the
clearing and settlement banks approximately twenty days following the end of
each month.

  The Company's merchant customers have liability for charges disputed by
cardholders. However, in the case of merchant insolvency, bankruptcy or other
nonpayment, the Company may be liable for any of such charges disputed by
cardholders. The Company believes that the diversification of its merchant
portfolio among industries and geographic regions reduces its risk of loss.
Based on its historical loss experience, the Company has established reserves
for estimated credit losses on transactions processed.

  FINANCING LEASES.   The Company provides direct financing leases and sales-
type leases to its customers. The significant difference between the two types
of leases is dealer profit recognized in a sales-type lease. At inception of a
POS equipment lease, the Company records an investment in direct financing
leases which is equal to the total of future lease rentals and the estimated
residual value of the leased equipment less unearned income. The unearned income
is the difference between the cost of the equipment and the total of future
lease rentals plus the estimated residual value of the leased equipment.
Residual value is based on the estimated proceeds from the sale or lease of the
asset at the end of the lease term. Amortization of unearned income is recorded
using the effective interest method. The investment in financing leases is
reduced by an allowance for rental payments that are expected to be
uncollectible.

  INVENTORY. Inventory, which consists of electronic POS equipment held for sale
or rental to merchants, is stated at the lower of cost or market. Cost is
determined using the first-in, first-out method.

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)
                                        
  PROPERTY AND EQUIPMENT.  Property and equipment is stated at cost less
accumulated depreciation. Depreciation is calculated using the straight-line
method for financial reporting purposes and primarily accelerated methods for
tax purposes. For financial reporting purposes, equipment is depreciated over
three to seven years and buildings are depreciated over thirty years. Leasehold
improvements and property acquired under capital leases are amortized over the
useful life of the asset or the lease term, whichever is shorter. Direct costs
associated with the development of software for internal use are capitalized and
depreciated over the useful life of the software, up to seven years. Maintenance
and repairs are charged to expense as incurred. Expenditures for renewals and
improvements that extend the useful life are added to the property and equipment
accounts. The Company rents POS equipment to merchants under operating leases.
The rented equipment is capitalized and depreciated over three years.

  FINANCIAL INSTRUMENTS.  The Company's financial instruments at December 31,
1998 and 1997 consist primarily of cash and cash equivalents and loans payable
to financial and lending institutions. Due to the short maturities of the cash
and cash equivalents, carrying amounts approximate the respective fair values.
The loans payable are variable rate instruments at terms the Company believes
would be available if similar financing were obtained from another third party.
As such, their carrying amounts also approximate their fair value.

  Financial instruments that potentially subject the Company to significant
concentrations of credit risk consist principally of trade accounts receivable
and cash investments. Concentrations of credit risk with respect to trade
accounts receivable are limited, due to the large number of entities comprising
the customer base and the ongoing credit evaluations conducted to monitor the
status of a customer's financial condition. Cash investments are held by
numerous financial institutions and present minimal risk to the Company.

  INTANGIBLES.  The excess cost of businesses acquired is amortized on the
straight-line basis over thirty years. Accumulated amortization at December 31,
1998 and 1997, was $2.6 million and $2.1 million, respectively. Amortization
expense was approximately $573,000, $500,000 and $496,000 for the years ended
December 31, 1998, 1997 and 1996, respectively.

  Amortization of merchant portfolios is provided on a straight-line basis over
a ten-year life, based on the Company's estimates of future merchant sales
volumes. Accumulated amortization of portfolios was $63.1 million and $31.9
million at December 31, 1998 and 1997, respectively. Amortization expense was
approximately $ 30.0 million, $14.0 million, and $8.4 million for the years
ended December 31, 1998, 1997, and 1996, respectively.

  Management periodically evaluates intangibles for indications of impairment
based on the operating results of the related business or merchant portfolio
purchased. If this evaluation indicates that the intangible asset will not be
recoverable, as determined based on the undiscounted cash flows over the
remaining life of the asset, the carrying value and remaining amortization
period of the related intangible asset will be adjusted to reflect fair value.

  INCOME TAXES.  The Company accounts for income taxes pursuant to the
provisions of Statement of Financial Accounting Standards No. 109, "Accounting
for Income Taxes" ("SFAS 109"). Under this method, deferred tax assets and
liabilities are recorded to reflect the future tax consequences attributable to
the effects of differences between the carrying amounts of existing assets and
liabilities for financial reporting and their respective amounts used for income
tax purposes.

  SETTLEMENT OBLIGATIONS.  Settlement obligations result from timing differences
in the Company's settlement processes with merchants.

  STOCK COMPENSATION.  NOVA has elected under the provisions of Statement of
Financial Accounting Standards No. 123, "Accounting for Stock-Based
Compensation" ("SFAS 123") to continue to use the intrinsic-value method of
accounting for employee stock-based compensation in accordance with Accounting
Principles Board Opinion Number 25, "Accounting for Stock Issued to Employees"
("APB 25"). Refer to Note 12 regarding pro forma net income (loss) and earnings
per share information.

  EARNINGS PER SHARE.  Basic earnings per common share is computed using the
weighted average number of common shares outstanding during the period. Diluted
earnings per common share is computed using the weighted average number of
common shares outstanding during the period and reflects any dilutive effects of
options, warrants and convertible securities outstanding during the period.

  RECENT PRONOUNCEMENTS.  In June 1998, the Financial Accounting Standards Board
issued Statement No. 133, "Accounting for Derivative Instruments and Hedging
Activities," which is required to be adopted in years beginning after June 15,
1999. Because of the Company's minimal use of derivatives, management does not
anticipate that the adoption of the new Statement will have a significant effect
on earnings or the financial position of the Company.

  PRESENTATION.  Certain 1997 and 1996 amounts have been reclassified to conform
to the 1998 presentation.

                             BUSINESS COMBINATIONS

PMT SERVICES, INC. MERGER

  In September 1998, NOVA completed the acquisition of PMT Services, Inc.,  in a
merger transaction by exchanging 37,651,000 shares of its common stock for all
of the outstanding common stock of PMT. Each share of PMT was exchanged for
0.715 of one share of NOVA common stock. In addition, outstanding PMT options
and warrants were converted at the same exchange factor of NOVA common stock.
See Note 12.

  The combined results reflect reclassifications to conform financial

OTHER BUSINESS COMBINATIONS

     As previously stated, PMT completed various business combinations in the
year ended October 31, 1998, and the two years ended July 31, 1997, by issuing
common stock in exchange for all of the outstanding common stock of the
companies acquired. These transactions were accounted for as pooling of
interests. The consolidated accompanying financial statements have been prepared

     MHA had a calendar year end. In order to conform MHA's year end to PMT's
fiscal year end, results of operations for MHA for the six-month period ended
June 30, 1996, have been excluded from the consolidated statement of operations
for the year ended July 31, 1996. Accordingly, an adjustment has been made in
1996 to retained earnings for the exclusion of the net loss of $356,914 for such
six-month period. MHA's results of operations for this six-month period include
revenues of $10.7 million, expenses of $11.0 million and net loss before
provision for income taxes of $279,053.     

     Fairway, RPS, Krueger, Bancard, MBN and Superior were Subchapter S
Corporations for income tax purposes; therefore, these entities did not pay U.S.
federal income taxes. These entities will be included in the Company's U.S.
federal income tax return effective from the date of each merger.
    
     In addition to these transactions, PMT completed six separate operating
business combinations during the year ended October 31, 1998, and the year ended
July 31, 1997, with six unrelated entities. PMT issued an aggregate of 3,577,914
shares of common stock, on a converted basis, in exchange for all the
outstanding stock of the six entities. On an individual basis these
transactions, which were accounted for as poolings of interests, were not
considered material for retroactive restatement of the consolidated financial
statements. Retroactive restatement would have increased total assets by 1% as
of December 31, 1997. Retroactive restatement would have increased revenue by 4%
and 5%, and net income by 4% and 8%, during 1997 and 1996, respectively.

MERCHANT PORTFOLIOS

     NOVA purchases various merchant portfolios, whereby servicing rights for
electronic authorization and payment processing to specific merchants under
contract to processing banks are acquired. The Company's operating results
reflect each of these purchases from the effective dates of the transactions.
During 1998 there was one significant portfolio purchase and several
individually insignificant purchases.

     Effective November 4, 1998, the Company completed a transaction with First
Union Bank of Delaware, successor by merger to CoreStates Bank of Delaware, N.A.
("CoreStates"), whereby NOVA acquired all rights, title, and interest in and
assumed certain liabilities of the CoreStates merchant processing portfolio. The
remaining purchase price, payable over a two-year period, is contingent upon
achieving certain minimum performance levels over the next two years. An initial
non-refundable payment of $25.0 million was made at the time of the purchase.
Contingent payments of up to $46.0 million may be required based upon the
performance of the portfolio.

     Significant 1997 merchant portfolio purchases include the Crestar Bank
merchant portfolio effective May 29, 1997, and the MBNA America Bank, N.A.
merchant portfolio effective December 31, 1997. Purchase price consideration
paid approximated $21.7 million and $20.3 million, respectively.

JOINT VENTURES

     In addition to merchant portfolio purchases, the Company also entered into
joint venture agreements with certain financial institutions for the purpose of
expanding and strengthening its merchant processing base. On January 21, 1998,
NOVA consummated a transaction with KeyBank National Association ("KeyBank")
whereby the Company purchased a 51% membership interest in Key Merchant
Services, LLC ("KMS"). NOVA provides transaction processing and other services
to the merchant contracts KeyBank initially contributed to the venture. The
purchase price of the membership interest is payable over a three-year period.
The purchase price recorded was $51.0 million, of which $37.1 million was paid
as of December 31, 1998. The remaining amount due is included in long-term debt
at December 31, 1998. The maximum consideration payable is approximately $74.1
million.

     Effective October 31, 1997, the Company entered into a joint venture with
Firstar Bank, U.S.A., N.A. ("Firstar") whereby NOVA purchased a 51% interest in
the joint venture for $24.0 million. The Company performs the transaction
processing services for the joint venture's merchant contracts.

     The following summarizes the allocation of the aggregate purchase price to
the major categories of assets acquired and liabilities assumed resulting from
all portfolio purchases and joint venture investments made by the Company:

                       MERGER AND CONSOLIDATION CHARGES
                                            
     As a result of NOVA's merger with PMT and other mergers completed by PMT
during 1998, the Company recorded a $90.7 million charge in 1998. This charge
was primarily related to direct merger transaction costs, charges associated
with the consolidation and closure of PMT's corporate headquarters and certain
operating subsidiaries, contract termination costs related to unfavorable third-
party processing contracts, and the decision to exit certain of PMT's sales
distribution channels.     

     Direct merger transaction costs are primarily investment banking
commissions, professional fees, and regulatory filing expenses.

     The primary costs associated with consolidation and closure of facilities
include employee and executive severance, estimated unrecoverable future lease
obligations on vacated facilities, and the write-down of capital assets to their
net realizable value. The consolidation and closure actions result from the
elimination of overlapping functions, primarily customer service, accounting,
and administrative areas. The total number of employees terminated was
approximately 275, with 210 having received severance packages as of December
31, 1998. Of these employees certain executives' severance will be paid out over
two years. The remaining employees will leave the Company during the first
quarter of 1999. The Company began the process of moving PMT's operations from

                                       14
<PAGE>
 
Nashville, Tennessee to other locations in December 1998, and expects the
process to be completed in the first quarter of 1999, at which time the premises
in Nashville will be completely vacated.

     Consistent with past practice, management developed a plan in 1998 to
convert the front-end and back-end transaction processing of PMT's merchants to
the NOVA Network. As a result of this plan, in 1998 the Company negotiated the
termination of long-term processing contracts with third parties which resulted
in early termination fees. The majority of these terminations were finalized and
paid in 1998. The Company expects to complete the negotiation and payment of the
remaining contracts during the first half of 1999, and the estimated costs are
included in the remaining reserve balance at December 31, 1998.

Capital asset write-downs are substantially attributable to the computer
software and equipment, including PMT's management information and financial
reporting systems. Additional assets written down include telephone systems, and
office furniture and equipment that will not be redeployed for use at another
NOVA facility.

     In 1998 management formulated plans to exit unique distribution channels
based upon the type of merchant business generated through these channels.
Specifically, servicing and maintaining the type of merchant generated through
these channels is not compatible with NOVA's operating philosophy and not
strategically aligned with NOVA's plan of business. The charge related to
exiting this distribution channel includes a contract termination fee and the
write-down of certain related intangible assets resulting from an analysis of
discounted future cash flows generated from the subject merchants.

     The majority of these merger related costs were paid in the fourth quarter
of 1998 and the Company expects the plans associated with the remaining costs to
be substantially complete during the first half of 1999.

     Details of the merger related charges are as follows:

     In March 1997, PMT entered into a ten year lease agreement for a portion of
office space available in a building that served as its corporate headquarters.
PMT granted a mortgage loan to an independent developer and advanced funds for
the purchase and renovation of the building. The outstanding loan amount of
$13.8 million, bears interest at 5%, with principal and interest of $80,562 due
monthly in arrears. The loan principal was issued in various draws based upon
completion of certain stages of renovation. The outstanding balance is payable
in full in August 2007. The mortgage loan is secured by a first lien on the
property. An independent appraisal of the property determined its fair value for
the purpose of classifying the related leasing transaction in accordance with
Statement of Financial Accounting Standards No. 13, "Accounting for Leases." The
lease is classified as an operating lease, and the minimum lease commitment is
included in Note 11.

     In October 1997, the Company entered into an agreement with a bank for
aggregate loans of up to $80.0 million. The Company, at its option and subject
to the satisfaction of certain conditions, may increase the aggregate amount
available on the credit facility to $100.0 million. On September 30, 2000, all
outstanding borrowings in excess of $50.0 million automatically convert to term
loans due in eight equal quarterly installments commencing December 31, 2000,
and ending September 30, 2002. All outstanding borrowings under the then
remaining $50.0 million revolving loan commitment are due September 30, 2002.
There were no outstanding borrowings against this facility at December 31, 1998.

     The Company pays a quarterly commitment fee in arrears on the average daily
unused portion of the funds available for revolving loans and letters of credit.
This commitment fee ranges from .125% to .200% depending on certain financial
ratios. The Company also pays commitment fees for outstanding letters of credit.
Such fees range from .35% to .65% depending on certain financial ratios.
Interest on outstanding borrowings is charged using, at the Company's option,
either the bank's base rate, as defined, or the prevailing Eurodollar rate plus
a margin determined from certain financial ratios.

     Borrowings under the loan agreement are collateralized by substantially all
the assets of the Company. The loan agreement contains restrictive covenants
that include, among other items, maintenance of specified ratios of EBITDA
(earnings before interest, taxes, depreciation and amortization) to fixed
charges and funded debt and restrictions on the payment of dividends. In
connection with the PMT Merger and other acquisitions closed in 1998 and 1999,
the Company obtained a waiver of certain covenants under the Credit Agreement,
which is effective for all applicable periods.

     As a result of the PMT acquisition, the Company also has a $20.0 million
revolving line of credit available, which expired without renewal on January 31,
1999. There were no outstanding borrowings at December 31, 1998 or 1997.

  In assessing the likelihood of utilizing existing net deferred tax assets,
management considered its current operating environment, future ability to
generate sufficient taxable income, and the excess of its appreciated asset
values over the related tax basis. At this time, management believes it is more
likely than not that the deferred tax assets will be realized based on its
assessment of current financial condition.

  The Company has approximately $300,000 of federal and state net operating loss
carryforwards available to offset future taxable income of certain subsidiaries.
These cumulative net operating loss carryforwards expire in varying amounts
through fiscal 2013.  A valuation allowance has been established for certain of
these net operating losses as utilization by the applicable subsidiaries is not
reasonably assured.

  PREFERRED STOCK.  The Company is authorized to issue 5,000,000 shares of
Preferred Stock in one or more series with such designations, powers,
preferences, rights, qualifications, limitations and restrictions as may be
fixed by the Board of Directors.

  On May 8, 1996, upon consummation of the Company's initial public offering,
the Series A, B and C Preferred Stock, totaling 28,571 shares, were converted
into 11,876,218 shares of common stock. In addition, the Company redeemed the
5,000 shares of Series D Preferred Stock outstanding for $5,000,000 on May 8,
1996. Cumulative dividends of $11,689,000 were paid to holders of Preferred
Stock concurrent upon the liquidation of all series of Preferred Stock.

  COMMON STOCK.   In connection with the PMT merger, NOVA amended its Articles
of Incorporation to increase the number of authorized shares of NOVA common
stock from 50,000,000 shares to 200,000,000 shares. The NOVA shareholders
approved the amendment at the special meeting of NOVA's shareholders held on
September 24,1998.
    
  On April 21, 1998, NOVA completed a public offering in which the Company sold
5,000,000 shares of common stock for a purchase price to the public of $30.00.
The net proceeds received from the sales of the shares on common  stock were
approximately $142.6 million after deducting underwriting discounts  and
commissions and estimated expenses. The Company used its net proceeds to repay
all amounts outstanding under its bank credit facility and to purchase various
merchant portfolios.

  The Company applies APB 25 and related interpretations in accounting for its
employee stock options. Under APB 25, if the exercise price of NOVA's employee
stock options equals the market price of the underlying stock on the date of
grant, no compensation expense is recognized. As discussed below, the
alternative fair value accounting provided for under SFAS 123 requires the use
of option valuation models that were not developed for use in valuing employee
stock options.

  Pro forma disclosures of net income (loss) and earnings per share pursuant to
SFAS 123, requires that the information be determined as if the Company has
accounted for its employee stock options granted subsequent to December 31,
1994, under the fair value method of that Statement. The fair value for these
options was estimated at the date of grant using a Black-Scholes option pricing
model with the following weighted-average assumptions:

of highly subjective assumptions, including the expected stock price volatility.
In management's opinion, the existing models do not necessarily provide a
reliable single measure of the fair value of its employee stock options because
the stock options have characteristics significantly different from those of
traded options, and changes in the subjective assumptions can materially affect
the fair value estimate.

  The pro forma amounts are indicated below:

  The pro forma amounts may not be representative of future disclosures since
the estimated fair value of stock options is amortized to expense over the
vesting period, and additional options may be granted in future years. The
Company sponsors seven stock option plans whereby the Company has reserved for
issuance upon exercise of stock options a maximum of 11,540,610 of NOVA common
stock, and 550,000 shares related to stock appreciation rights.

  The 1991 Employees Stock Option and Stock Appreciation Rights Plan ("1991
Plan"), the 1996 Employees Stock Incentive Plan ("1996 Employees Plan"), and the
NOVA Corporation 1996 Directors Stock Option Plan ("1996 Directors Plan") are
available to grant options. These plans are administered by a committee of the
Board of Directors that determines the number of shares to be granted and the
option price per share. Under these plans, the options expire no later than ten
years from the grant date.

  The 1991 Plan option awards may be exercised in 20% increments annually,
beginning on March 1 following the date of grant. No options or rights shall be
granted under the Plan after November 2, 2001. No appreciation rights have been
granted.

  Under the 1996 Directors Plan, options granted are exercisable in 25%
increments at the end of each of the four years subsequent to the date of grant,
and at a purchase price per share no less than the market value per share on the
grant date.

  The 1996 Employees Plan allows for the grants of incentive stock options, non-
qualified stock options, stock appreciation rights, and restricted stock awards.
On September 24, 1998, NOVA shareholders approved an amendment to increase the
number of shares issuable under the plan from 2,000,000 shares to 6,000,000
shares to facilitate future grants to all employees of NOVA after the PMT
Merger. Under the 1996 Employees Plan, options may be exercised in 25%
increments at the end of each of the four years subsequent to the grant date.
The administrative committee under the plan may amend or alter the vesting
schedule of the outstanding options. Incentive stock options cannot be granted
at a per share price less than the fair market value of the common stock on the
grant date.

  In connection with the PMT Merger, each outstanding option or warrant to
purchase PMT common stock became fully vested and was automatically converted
into an option or warrant to purchase the number of shares of NOVA common stock
in an amount and per share price adjusted to reflect the exchange ratio of
0.715. Each assumed option contains terms and provision similar to those terms,
conditions, and provisions contained in the original grant. The PMT plans are no
longer available for option grants. Approximately 2,300,000 million shares of
NOVA common stock have been reserved for issuance upon the exercise of such
options and warrants. Information contained in the tables presents the option
activity as if PMT shares had been converted from December 31, 1995.

                             PRO FORMA INFORMATION
                                            
  Pro forma earnings per common share is based on net income attributable to
holders of the Company's common stock (net income less dividends on Series D
Preferred Stock of $230,000 for the year ended December 31, 1996) and the
weighted-average number of common and common equivalent shares outstanding
during the period, assuming the conversion of Series A, B, and C Convertible
Preferred Stock into common sock. Pursuant to the requirements of the Securities
and Exchange Commission, common shares and common equivalent shares issued at
prices below the initial public offering price of $19.00 per share during the
ten months immediately preceding the date of the initial filing of the
Registration Statement have been included in the calculation of common shares
and common shares equivalents, using the treasury stock method, as if they were
outstanding for all periods presented. Weighted-average shares outstanding do
not include common stock equivalents which are anti-dilutive. All common shares
and per share data, except par value per share, have been retroactively adjusted
to reflect the 2.56-for-one stock split effected in the form of a stock dividend
of the Company's common stock, effective February 1996.

                                RELATED PARTIES

  The Company has entered into a multi-year agreement with a shareholder that
provides telecommunications service and support, primarily for the Company's
transaction processing network.  The amounts paid were approximately $ 7.0
million, $3.8 million and $2.5 million for the years ended December 31, 1998,
1997 and 1996, respectively.

  The Company paid another of its shareholders approximately $3.0 million, $3.3
million and $9.9 million in the years ended December 31, 1998, 1997 and 1996,
respectively, primarily for the utilization of the shareholder's labor force
during conversion and certain other transaction processing fees. Additionally,
the Company received approximately $1.5 million, $.9 million, and $1. 6 million
of interest income in the years ended December 31, 1998, 1997 and 1996,
respectively.

  As discussed in Note 3, the Company purchased the merchant processing
portfolio of CoreStates in November 1998. First Union, a shareholder of the
Company, acquired CoreStates prior to NOVA's acquisition of the Corestates
merchant processing portfolio.

                               RETIREMENT PLANS

  The Company maintains two non-qualified benefits plans, the NOVA Information
Systems, Inc. 401(k) and Profit Sharing Plan and the PMT Services, Inc. 401(k)
Retirement Plan ("the Plans"), which cover substantially all eligible employees
of the Company.  Participation eligibility is generally based upon completing
twelve consecutive months of employment and 1,000 hours or more of service.
Participants may elect to contribute up to 15% of their annual compensation,
subject to an annual limit of $10,000 in 1998.  Contributions can be made to
various available investment options.

  Under the NOVA Information Systems, Inc. 401(k) and Profit Sharing Plan, the
employer contribution is discretionary and may match a percentage of employees'
contributions. Under the PMT Services, Inc. 401(k) Retirement Plan, contribution
amounts were 50% of employee voluntary contributions, up to a maximum of 6% of
the employee's annual compensation. The Company may also elect to make an
additional contribution to the Plans on behalf of eligible employees. During the
years ended December 31, 1998, 1997, and 1996, Company contribution expenses for
the Plans were not significant.

  The Company has experienced, and expects to continue to experience,
significant seasonality in its business. The Company typically realizes higher
revenues in the fourth calendar quarter and lower revenues in the first calendar
quarter, reflecting increased transaction volumes during the summer months and a
significant decrease in transaction volume during the period immediately
following the holiday season. Quarterly results are also affected by the timing
of merchant portfolio purchases and the timing and magnitude of expenses for
merchant portfolio conversions. Therefore, the results reported in the table
above do not necessarily indicate the Company's normal seasonal trends.
