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 5. Management's Discussion
and Analysis of Financial Condition and Results of Operations" contained herein,
for a more complete discussion of certain risk factors.


                                     PART I

ITEM 1.   BUSINESS

  NOVA Corporation is a provider of integrated transaction processing services,
related software application products and value-added services primarily to
small- to medium-sized merchants.  NOVA provides transaction processing support
for all major credit, charge and debit cards, including VISA, MasterCard,
American Express, Discover, Diner's Club, and JCB, as well as check verification
services.  On a pro forma basis giving effect to the recent transactions
discussed below, the aggregate dollar volume of VISA and MasterCard transactions
NOVA processed in 1998 would have exceeded $48 billion on an annualized basis.

  NOVA provides merchants with a broad range of transaction processing services,
including authorizing card transactions at the point-of-sale ("POS"), capturing
and transmitting transaction data, effecting the settlement of payments, and
assisting merchants in resolving billing disputes with their customers.  In
addition, NOVA has developed several software applications that can be delivered
to its customers and updated for enhancements via NOVA's proprietary
telecommunications network (the "NOVA Network").  The NOVA Network, initially
developed by NOVA in conjunction with MCI WorldCom, Inc. ("MCI WorldCom"), is
the principal conduit through which NOVA provides its services. By combining its
ability to employ technology effectively with the capabilities of the NOVA
Network, NOVA is able to respond quickly and efficiently to the ever changing
and diverse needs of its merchant customers.

                                       3

  NOVA was incorporated in Georgia in December 1995 in connection with an
alliance (the "First Union Alliance") between NOVA and First Union Corporation
("First Union"). NOVA Information Systems, Inc. ("NOVA Information
Systems"), a wholly-owned subsidiary and predecessor to NOVA, was incorporated
in Georgia in February 1991. On September 24, 1998, NOVA acquired PMT Services,
Inc. ("PMT") in a merger transaction, whereby PMT became a wholly-owned
subsidiary of NOVA.  Unless the context otherwise requires, references in this
Annual Report on Form 10-K to "NOVA" or "the Company" refer to NOVA
Corporation and its subsidiaries.

Significant Transactions, Alliances and Marketing Arrangements

   PMT Merger. Effective September 24, 1998, NOVA acquired PMT in a merger
transaction (the "PMT Merger"). PMT is an independent sales organization ("ISO")
that markets and services electronic credit card authorization and payment
systems to merchants located throughout the United States. PMT experienced
significant growth by utilizing operating and growth strategies focused on
expanding its customer base of small- to medium-sized merchants through merchant
portfolio purchases, trade and other association affiliations, telemarketing
efforts, subsidiary sales force acquisitions.

   At the effective time of the PMT Merger, each outstanding share of PMT common
stock was converted into and exchanged for .715 shares of NOVA common stock.
Additionally, each outstanding option or warrant to purchase shares of PMT
common stock, whether or not then exercisable, became fully vested at the
effective time of the PMT Merger.  Each of these options and warrants was
converted automatically into an option or warrant to purchase shares of NOVA
common stock based on the exchange ratio of .715. As a result of the PMT Merger,
NOVA issued approximately 37,651,000 shares of NOVA common stock and reserved
approximately 2,300,000 shares of NOVA common stock for issuance upon the
exercise of options and warrants converted in the PMT Merger.

   NOVA accounted for the PMT Merger as a pooling of interests, and accordingly
restated financial statements to include the historical financial information of
the combined operations for NOVA and PMT for all periods presented.  NOVA and
PMT determined the terms of the PMT Merger, including the consideration payable
by NOVA, through arms-length negotiations.

   In connection with the PMT Merger, NOVA shareholders approved an amendment to
NOVA's Articles of Incorporation that increased the number of shares of NOVA
common stock authorized from 50,000,000 to 200,000,000.  The shareholders also
approved an amendment to NOVA's 1996 Employees Stock Incentive Plan (the "1996
Employees Plan"), which increased the number of shares of NOVA common stock
issuable pursuant to the 1996 Employees Plan from 2,000,000 to 6,000,000.

   KMS Joint Venture. In January 1998, NOVA purchased from KeyBank a 51%
interest in Key Merchant Services, a Delaware limited liability company ("KMS").
Pursuant to this agreement, NOVA provides transaction processing services to the
merchant customers of KMS and is responsible for its operation and management.
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 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.

   KMS has an initial operating term expiring in January 2005, with automatic
three-year extensions unless either KeyBank or NOVA gives notice of termination
at least 12 months prior to the scheduled

                                       4
<PAGE>
 
expiration date. KMS is governed by a management committee comprised of three
members designated by NOVA and two members designated by KeyBank. In addition,
NOVA's designee, who serves as manager of KMS, has the power and authority to
make decisions and take actions in connection with the day-to-day operation of
KMS in the ordinary course of business. KeyBank markets, promotes and refers
NOVA's services through its bank branch network to merchants who express an
interest in bankcard processing services. Additionally KMS has a dedicated sales
force comprised of approximately sixty people to solicit directly new merchant
business on behalf of KMS. Upon termination or expiration of KMS, either KeyBank
or NOVA, depending on the circumstances, may elect to purchase the other party's
interest in KMS at ''fair market value'' determined pursuant to the terms of the
KMS operating agreement.

   MBNA Portfolio Purchase.  On December 30, 1997, NOVA purchased substantially
all of the merchant portfolio of MBNA America Bank, N.A. ("MBNA").  In
connection with the transaction, MBNA agreed to cooperate with NOVA in marketing
NOVA's merchant transaction processing services and to refer exclusively to NOVA
all merchants, trade associations, financial institutions, ISOs and other
organizations that request or evidence an interest in merchant transaction
processing services.  NOVA, among other things, is required to pay to MBNA a fee
for each merchant that enters into a merchant transaction processing contract
with NOVA as a result of a referral from MBNA. NOVA is also required to pay to
MBNA a percentage of the portfolio's net revenues.

   NOVA's marketing agreement with MBNA has an initial term expiring December
31, 2007 subject to automatic two-year extensions unless either party gives
notice of termination at least seventy-five days prior to an expiration date.
The MBNA portfolio added approximately $1.0 billion in annualized credit and
debit card transaction processing volume during 1998.

   Elan Merchant Services.   Effective October 31, 1997, NOVA purchased from
Firstar Bank U.S.A., N.A. ("Firstar") a 51% interest in Elan Merchant Services,
LLC ("Elan"). During 1998, Elan contributed processed volume of approximately
$3.3 billion to NOVA's operating platform.

   Elan has an initial term expiring on August 31, 2008, with automatic one-year
extensions unless either Firstar or NOVA, as the sole members of Elan, gives
notice of termination at least six months prior to a scheduled expiration date.
Although certain powers are reserved exclusively in a management committee,
NOVA, as manager of Elan, has the power and authority to make decisions and take
actions on behalf of Elan in connection with its day-to-day operation and
management in the ordinary course of business. The management committee is
comprised of four persons, with two members selected by each of Firstar and
NOVA. Elan pays NOVA an annual fee for its managerial services. NOVA also
provides Elan with transaction processing and other services for which NOVA
receives compensation. Firstar markets and promotes, on an exclusive basis,
transaction processing services on behalf of Elan directly and through a network
of over 850 correspondent financial institutions. Elan, among other things, is
required to pay to Firstar a fee for each merchant that enters into a merchant
transaction processing contract with Elan as a result of any such referral,
including a fixed percentage of sales volume the referred merchant processes
through NOVA. Firstar and its affiliate banks also agreed to provide certain
other services, including clearing and settlement services to Elan for which
Firstar receives compensation. Upon termination or expiration of the Elan joint
venture, either Firstar or NOVA, depending on the circumstances of such
termination or expiration, may elect to purchase the other party's interest in
at the "fair market value" determined through negotiations between the parties
at the time of termination. If Firstar and NOVA are unable to mutually agree
upon the "fair market value," an independent appraiser shall make such
determination.


   CoreStates Portfolio. Pursuant to an agreement dated October 8, 1998, NOVA's,
wholly-owned subsidiary, NOVA Information Systems acquired the merchant
processing portfolio of First Union National Bank of Delaware ("FUBD"),
successor by merger to CoreStates Bank of Delaware, N.A. ("CoreStates"). FUBD is
a wholly-owned subsidiary of First Union. The purchase included all right,
title, and interest in and assumption of certain liabilities of CoreStates'
merchant processing portfolio. The purchase price, payable over a two-year
period, is contingent upon the portfolio achieving certain minimum performance
levels. An initial, non-refundable payment

                                       5
<PAGE>
 
of $25.0 million was made at the time of the purchase, and additional payments
may be made subject to achievement of the performance requirements. The total
purchase price will not exceed $71.0 million.

Industry Overview

   The transaction processing industry provides merchants with credit, charge
and debit card and other payment processing services, as well as related
information services. This industry has grown rapidly in recent years as a
result of wider merchant acceptance and increased consumer use of such cards and
advances in transaction processing and telecommunications technology. These
factors, together with efficiencies derived from economies of scale, have
resulted in the consolidation of transaction processing providers and the
availability of more sophisticated products and services to all market segments.

   Increased Growth in Card Use.   The proliferation in the uses and types of
credit, charge and debit cards, rapid technological advances in transaction
processing, and financial incentives offered by credit card associations and
issuers have contributed greatly to wider merchant acceptance and increased
consumer use of such cards. For example, industry sources indicate that for the
year ended December 31, 1997, charge volume of VISA and MasterCard and other
credit cards grew at an annual growth rate of approximately 9%, to $1.071
trillion.  Such sources project that the charge volume of general purpose cards
will increase an estimated 27.7%, or $296.6 billion by the year 2000, and will
exceed $2.0 trillion by 2005.  Industry sources also anticipate further
increases in credit and charge card acceptances as the number of general purpose
cardholders increases to an expected 160 million.  In 1997, the expanded use of
debit cards as an alternative to cash and checks at the point of sale increased
63% over 1996, to $119.1 billion. Industry sources anticipate that consumers
increased usage of debit cards will eclipse the growth of credit cards in future
years. In 1997, 79% of transactions processed were with credit cards. Industry
sources further predict that by the year 2000 transactions processed with credit
cards will decrease to 64% as a result increasing debit card use. (The Nilson
Report--October 1998).

   Technology.   Rapid technological advances in transaction processing,
particularly the transition from paper-based to electronic processing, have
contributed greatly to wider merchant acceptance and increased consumer use of
such cards. Electronic processing provides greater convenience to merchants and
consumers, reduces fees charged to merchants, and facilitates faster and more
accurate settlement of payments. Increased card acceptance and usage, coupled
with technological advances in electronic processing, have created an
opportunity for service providers to offer a variety of sophisticated processing
and information services to a broader base of merchants.

   At present, many large transaction processors continue to provide customer
service and applications via legacy systems that often are difficult and costly
to alter, enhance, or customize. Accordingly, transaction processors that
continue to utilize these systems for customer service and applications may find
it difficult to meet the increasing demands of small- to medium-sized merchants
for more sophisticated products and services tailored to their diverse and
changing needs. In contrast to less flexible legacy systems, transaction
processors utilizing less costly, scalable and networked computer systems,
(including distributed client/server architecture and relational database
management systems solutions), enjoy greatly improved flexibility and
responsiveness in providing customer service and applications to its customer
base. In addition, the use of fiber optic cables and advanced switching
technology in telecommunications networks and competition among long-distance
carriers further enhance the ability of processors to provide faster and more
reliable service at lower per-transaction costs than previously possible.

   As a result of advances in personal computer and POS terminal technologies,
transaction processors can provide merchants with expanded access to a greater
array of sophisticated services at the POS, resulting in increased demand for
such services. In addition, merchant use of increasingly sophisticated
integrated cash registers and networked systems has created further demand for
comparably advanced and sophisticated products and services accessible at the
POS. These trends have created opportunity for transaction processors to
leverage technologies by developing business management and other software
application products and services.

   Segmentation of Merchants and Service Providers.   The transaction processing
industry is characterized by a small number of large transaction processors that
focus primarily on servicing large merchants and by many smaller transaction
processors that provide a limited range of services to small- to medium-sized
merchants. Large merchants (i.e., those with multiple locations and high volumes
of card transactions) typically demand and receive the full range of transaction
processing services as well as customized information services at low per-
transaction costs. By contrast, transaction processors historically have not
offered small- to medium-sized merchants the same level of services as large
merchants or relatively low per-transaction costs offered to larger merchants.
The growth in card transactions and the transition from paper-based to
electronic transaction processing have, however, caused small- to medium-sized
merchants increasingly to demand sophisticated transaction processing and
information services similar to those provided to large merchants.

   Community and regional banks and ISOs are the primary groups that market and
sell transaction processing services to small- to medium-sized merchants.
Typically, these banks and ISOs outsource all or a portion of the transaction
processing services they offer. It is difficult, however, for banks and ISOs to
customize transaction processing services for the small- to medium-sized
merchant on a cost-effective basis or to provide sophisticated value-added
services. Accordingly, services to small- to medium-sized merchants historically
have been characterized by basic transaction processing services without the
availability of the more sophisticated processing, information-based services,
or customer support offered to large merchants.

   Consolidation.   The transaction processing industry has undergone rapid
consolidation over the last several years. The costs to convert from paper-based
to electronic processing, merchant requirements for improving their customer
service, and the demands for additional customer applications have made it
difficult for community and regional banks and ISOs to remain competitive. Many
of these processors are unwilling or unable to invest the capital required to
meet evolving market demands, and are increasingly exiting the transaction
processing business, or otherwise seeking alliance partners to provide
transaction processing to their customers. Despite this ongoing consolidation,
the industry remains fragmented. Management believes that although the ten
largest bankcard processors account for a significant portion of the total
charge volume processed there are several hundred additional registered service
providers marketing and selling transaction processing services to merchants.
Management believes that these factors will result in continuing industry
consolidation opportunities over the next several years.

Merchant Services Provided by NOVA

   Authorization Services.   NOVA provides electronic transaction authorization
services for all major credit and charge cards and debit cards. Authorization
generally involves approving a cardholder's purchase at the POS after verifying
that the card has not been reported lost or stolen and that the purchase amount
is within the cardholder's credit or account limit. The electronic authorization
process for a credit card transaction begins when the merchant "swipes" the card
through its POS terminal and enters the amount of the purchase. After capturing
the data, the POS terminal transmits the authorization request via the NOVA
Network to NOVA's switching center, where the data is routed to the appropriate
credit card association for authorization. The credit card association then
approves or declines the transaction and the response is transmitted back to
NOVA's switching center, where it is routed to the appropriate merchant.

   Data Capture and Reporting Services.   At the time of authorization, data
relating to the transaction, such as the purchase price and card number, is
recorded electronically both at the merchant's POS terminal and by NOVA. This
data replication maximizes NOVA's ability to reconcile transaction data with
each merchant and to protect against potential loss of data. On a periodic basis
throughout the day, the merchant aggregates and organizes this transaction data,
using a software application that NOVA has programmed into the merchant's POS
terminal, and transmits this information to NOVA where it is organized into
various files. These files are transmitted to either primarily Vital Processing
Services L.L.C. ("Vital"), Mellon Bank ("Mellon"), or First Data Resources
("FDR") (collectively "merchant accounting vendors"), for merchant accounting as
described below. NOVA maintains a file in its database from which NOVA runs
"Witness," its proprietary fraud detection software program against each of the
day's transactions processed via the NOVA Network. NOVA also

                                       7
<PAGE>
 
utilizes this information to provide merchants with information services such as
specialized management reports and to facilitate its other customer service
operations. Merchants can access this archived information through NOVA's
customer service representatives or through applications such as NOVA ACS and
NOVA Perks, which allow the merchant direct access to NOVA's database through a
personal computer.

   Settlement, Accounting and Clearing Services. NOVA assigns each of its
merchant customers to a merchant accounting vendor which perform merchant
accounting services on NOVA's behalf. At least once each day, NOVA forwards to
the merchant accounting vendors transaction data regarding its merchant
customers. The merchant accounting vendors reorganize and accumulate the data on
a merchant-by-merchant and card issuer-by-card issuer basis and forward the data
to the credit card associations for ultimate payment. On a monthly basis, each
merchant accounting vendor send statements to NOVA's merchant customers for whom
they provide settlement and accounting services, detailing the previous month's
transaction activity.

   NOVA is registered with VISA and MasterCard as a certified processor and
member service provider.  Regions Bank, Bank of the West, Imperial Bank, First
National Bank of Omaha ("FNBO"), Zions Bank, Firstar, KeyBank and First Union
National Bank ("FUNB") a subsidiary of First Union, serve as the primary member
clearing banks for NOVA. NOVA's clearing banks receive payment for merchant
transactions from the credit card associations (net of fees payable to the
credit card associations and card issuing banks), from which the clearing banks
remit payment to the merchant for the gross amount of the merchant's
transactions. Once each month, NOVA collects applicable merchant discount and
other fees from each merchant for transactions effected and services provided
during the preceding month.

   Chargeback Services.   In the event of a billing dispute between a cardholder
and a merchant, NOVA assists the merchant in investigating and resolving the
dispute. These billing disputes include, among others: (i) non-receipt of
merchandise or services; (ii) unauthorized use of a credit card; and (iii)
quality of the goods purchased or the services rendered. NOVA provides a
sophisticated chargeback control system for its merchants, utilizes proprietary
software programs to actively prescreen disputes and  automated chargeback
controls. These chargeback control systems enable NOVA to reduce the time and
expense spent on cardholder requests for chargebacks. In the event a billing
dispute between a cardholder and a merchant is resolved in favor of the
cardholder, the transaction is "charged back" to the merchant and that amount
is credited or otherwise refunded to the cardholder. If NOVA or its clearing
banks are unable to collect such amounts from the merchant's account, and if the
merchant refuses or is unable to reimburse NOVA for the chargeback, NOVA bears
the loss for the amount of the refund paid to the cardholder.

   Customer Service and Support.   NOVA provides its merchant customers with a
variety of customer services and support. These services include the provision
of POS terminals (on sale or lease basis), software application downloads for
POS terminals, POS terminal maintenance and customized software for merchant
development. In addition, NOVA maintains a 24-hours-a-day, seven-days-a-week
helpline staffed by full-time customer service representatives.

Technology

   One of NOVA's principal strategies is to utilize available technologies to
deliver transaction processing and related software application products and
services on a cost-effective basis. To effect this strategy, NOVA regularly
adapts and uses technologies developed for applications outside the transaction
processing industry. In particular, technologies developed for networked PCs and
the telecommunications market have been important to the NOVA Network and NOVA's
service capabilities.

   NOVA exercises significant control over the development and enhancement of
the combination of hardware, software and network services that comprise its
transaction processing and information delivery system. This provides NOVA with
greater control over the functionality, quality, reliability, cost and
efficiency of its transaction processing services and related software
application products and services.

                                       8

   The NOVA Network.   The NOVA Network, initially developed in conjunction with
MCI WorldCom, is NOVA's proprietary telecommunications network and the principal
conduit through which NOVA provides services  to merchants. The NOVA Network's
design provides efficient switching capabilities, resulting in rapid response
time for transaction authorizations. The NOVA Network employs high speed
switching and routing communications, supplying substantial bandwidth capable of
supporting sophisticated value-added services. In working with MCI WorldCom,
NOVA designed a network specifically tailored to the services NOVA desired to
provide, the equipment needed to furnish those services and the functionality
those services were designed to achieve. As customer needs change and as
technology improves, management believes that it will be able to adapt and
customize the NOVA Network as necessary to achieve the functionality it desires.
Currently, both MCI WorldCom and AT&T Corp. provide long-distance service as
well as technical support for the NOVA Network. NOVA's long distance service and
support agreement with MCI WorldCom expires in July 2001. The agreement is
subject to earlier termination by NOVA if MCI WorldCom fails to meet certain
agreed-upon performance objectives. Local access is provided by a subsidiary of
MCI WorldCom and by BellSouth Corporation

   The NOVA Network utilizes Integrated Services Digital Network ("ISDN") and
its associated Non-Facilities Associated Signaling ("NFAS") features. The NFAS
features of the NOVA Network facilitate portability of the NOVA Network to long-
distance and local telecommunications access. This enhanced portability enables
NOVA to utilize alternate long-distance providers, and, therefore, to demand
competitive tariffs. NOVA has developed and tested a network interface with
other long-distance providers and management believes that, if necessary or
convenient, NOVA could utilize the telecommunications access of other providers
in connection with the NOVA Network. Management believes that transferring the
NOVA Network to AT&T, or another telecommunications access provider, can be
accomplished without sacrificing any significant performance or operational
attributes of the NOVA Network, although such a transfer may increase NOVA's
expenses for network services.

   The reliability of the NOVA Network is enhanced by the backup service
provided by AT&T. The existence and maintenance of this backup system, which is
designed so no single element is shared with the principal MCI WorldCom system,
enhances NOVA's ability to provide a high level of reliability in its network
service. Through an agreement with Electronic Data Systems Corporation, NOVA
maintains a voice authorization backup system. This backup system allows
merchants to receive voice authorization of transactions in the event of a POS
terminal malfunction, network outage or other similar circumstances.

   An advantage of the NOVA Network is its resiliency and routing capabilities.
After a POS transaction reaches the NOVA Network via either MCI WorldCom or
AT&T, it is immediately converted to ("TCP/IP") protocol.  Once converted, the
transaction is switched and routed through the NOVA Network via the optimal
path. Unlike some transaction processing companies that employ a front-end
processor switch and a back end switch, NOVA's proprietary TCP/IP routing
network provides a competitive advantage in the transaction processing industry.
The NOVA Network is TCP/IP based, which positions NOVA to explore Internet
commerce opportunities.  As the Internet is a large, public TCP/IP network,
processing Internet originated transactions is a logical extension of NOVA's
core competency.  NOVA maintains a fully redundant, three-tier meshed network
utilizing 3COM Corporation switches and routers. In addition, NOVA uses Open
Shortest Path First ("OSPF") routing protocol to ensure the optimal path is
always utilized between the modems on the network front-end and the NOVA host.
OSPF also ensures  speedy network rerouting in the event of hardware failure.

   Software Development for POS Terminals and PCs.   NOVA continuously develops
new software applications for POS terminals and PCs in an effort to improve
existing and create additional product and service offerings. NOVA's software
development capability is critical to its ability to respond flexibly to
changing customer needs and improving technologies. NOVA has programmed most of
the POS terminals utilized by its merchant customers with specific applications.
By programming POS terminals, NOVA can avoid the limitations of the preexisting
applications programmed into POS terminals, which are designed for broad
applicability to a wide range of users, and can provide its merchant customers
with specifically tailored applications at an increased level of functionality.

                                       9
<PAGE>
 
Since NOVA generally distributes such software application products  by
downloading such applications over the NOVA Network,  merchants are able to
utilize NOVA's products and services quickly and inexpensively.

   As NOVA's merchants are increasing their use of PCs and fully-integrated cash
registers and payment systems, NOVA is extending its POS terminal software
application product and service offerings to PCs and expanding the number of its
products and services available for PC use or that otherwise allow the POS
terminal to interface with a PC. For instance, NOVA ACS, NOVA-Perks, PC
Transact_It, and NOVA Shadow Pay are PC-based applications.  While merchant use
of such products and services currently is limited, and there can be no
assurance that such products and services will be widely accepted, NOVA expects
such use to increase. NOVA and First Union are actively pursuing with KeyBank
and other third parties initiatives relating to transaction processing via the
Internet and procurement and purchasing cards.  Management believes that these
and other efforts may result in the development of additional software
application products and value-added services.

   NOVA actively encourages third party software developers to write
applications to NOVA's specifications and network protocols. These applications,
once certified by NOVA, allow integration of NOVA's transaction processing
services with the business management software created by such developers for
use at the merchant's POS. These developers often function as value-added
resellers ("VARs") for NOVA as they frequently market their business
management software in connection with NOVA's services. For example, NOVA
recently developed NOVA TransPort,  which consists of client and server software
that encrypts transactions via the Internet.  NOVA makes this software available
to VAR's to integrate into their applications. GO Software, Inc., one of the
first VAR's to integrate this software into their application line, has several
products capable of sending encrypted transactions via the Internet directly to
NOVA for processing.  Merchants enjoy dedicated, leased-line performance at
Internet connection costs for transaction processing.  In this way, VARs such as
GO Software, Inc. indirectly perform a marketing function for NOVA since they
often offer their software  on a fully-integrated basis with NOVA's transaction
processing services, creating additional opportunities to reach small- to
medium-sized merchants. NOVA has certified in excess of 100 third party software
developers, including Aluim Payment Groups, Atomic Software, Southern DataCom,
Inc., Datacap, Inc., Tellen Software Inc., and UniPay.

   Use of Networked Systems for Customer Service.   As a result of the
information access and retrieval capabilities of networked systems, which
provide real-time information to any of NOVA's customer service representatives,
NOVA can provide a level of customer service and support to small- to medium-
sized merchants historically available only to much larger merchants. For
example, any of NOVA's customer service representatives may access, on a real-
time basis, all of the relevant information pertaining to any particular
merchant that may call and ask for assistance. NOVA also recently implemented an
on-line, informational database that provides NOVA's customer service
representatives user-friendly access to an array of additional information
relative to NOVA's services, products and systems, which often allows NOVA to
more quickly and effectively resolve customer service inquiries. Additionally,
the NOVA Network is highly automated and requires minimal staffing, which allows
NOVA to contain costs and achieve greater operating efficiencies.



Software Application Products and Value-Added Services

   In addition to card transaction processing, NOVA offers related software
application products and value-added services to its merchant customers. NOVA
designed these products and services  to run on existing POS terminals and DOS-
and Windows-based PCs. An integral part of NOVA's strategy is the offering of a
broad range of products and services historically unavailable to small- to
medium-sized merchants.  By  focusing on these merchants, NOVA seeks to
differentiate itself among the banks and ISOs serving this portion of the
market. Management believes that the quality and reliability of its products and
services enhance NOVA's ability to attract and retain merchant customers.

   NOVA currently offers a variety of software application products and value-
added services, including the following core products and services that are
basic to the NOVA Network:

                                       10
<PAGE>
 
   NOVA ENCOMPASS. NOVA Encompass is the latest generation of NOVA's user
interface. NOVA presently provides NOVA Encompass to all new merchant customers,
and generally charges a one-time fee to upgrade existing merchants to NOVA
Encompass. In addition to NOVA's core transaction processing services, NOVA
Encompass enables merchants to access NOVA's software application products and
value-added services, including those described below. NOVA Encompass also
allows the merchant to access other business management applications, including
customized end-of-day processing (allowing, for instance, the performance by the
merchant of daily audit functions) and other review and reporting features
(e.g., summary report generation). Designed as a flexible "modular" system, NOVA
Encompass allows the merchant to add features and capability as its business
needs evolve.


   NOVA SHADOW PAY.   NOVA Shadow Pay addresses the increasing use by merchants
of integrated and modem-enabled cash registers and PCs. NOVA Shadow Pay
eliminates the necessity of a traditional, stand-alone POS terminal. NOVA Shadow
Pay is a PC application that allows the merchant's modem-enabled cash register
or PC to capture the transaction data that is keyed or otherwise input into the
cash register or PC, and transmits such data for authorization and processing,
eliminating both the need for a stand-alone POS terminal and redundant keying of
transaction data. In addition, NOVA Shadow Pay provides the merchant access to
certain review and reporting features allowing, for instance, the merchant to
more easily reconcile transaction activity for any given period with the data
captured and stored by the merchant's cash register or PC. NOVA charges a one-
time license fee for access to NOVA Shadow Pay.

   NOVA MASS TRANSACT and PC TRANSACT_IT.   NOVA Mass Transact is a mainframe-
to-mainframe transaction processing application that NOVA developed specifically
for businesses utilizing mainframe technology and processing large numbers of
credit card transactions on a batch basis. A merchant using NOVA Mass Transact
(typically one that accepts a large number of credit card transactions by
telephone or mail) assembles a batch file of transactions and the merchant's
mainframe transmits that information to NOVA for processing. Insurance companies
and magazine publishers, each of which process large numbers of transactions for
recurring payments such as insurance premiums and subscription renewals,
respectively, are examples of the type of merchant customers who currently
utilize NOVA Mass Transact. PC Transact_It is a similar application that allows
PCs, rather than mainframes, to process transactions on a batch basis. Merchants
who subscribe to NOVA Mass Transact or PC Transact_It pay a one-time license fee
and a percentage of the amount of each transaction processed.

   INNRESPONSE AND NOVALODGE.   InnResponse and NOVALodge are transaction
processing applications designed to address the special needs of the hospitality
industry. InnResponse is a lodging solution for small hotels and motels and
tracks check-in and check-out data by portfolio. NOVALodge is a PC-based
application for larger hospitality facilities and accommodates multiple
terminals at a front desk as well as multiple on-site locations such as
restaurants, gift shops or golf facilities. Enhanced reporting provides totals
and allows sorting by terminal or location.

   NOVA Gratuit.   NOVA Gratuit is a transaction processing application designed
specifically for use by restaurants. NOVA Gratuit tracks server data and
includes "tip" capability and enhanced reporting capabilities. Similar to NOVA
Encompass, NOVA Gratuit software integrates a time clock into the software as
well as a frequent diner program.

   In addition to NOVA's core products and services, NOVA offers the following
value-added software applications and services:

   NOVA ACS.   NOVA ACS (Automated Customer Service) is a PC-based system that
allows NOVA's bank alliance and ISO partners access to NOVA's databases in order
to track and compile the transaction processing activity of their respective
merchant customers. Merchants also utilize NOVA to access NOVA's databases to
track and compile information regarding their own transaction activity. Through
such access and related information retrieval capabilities, NOVA ACS expands
greatly the banks', ISOs' and merchants' ability to design and obtain customized
informational reports and, in the case of banks and ISOs, to perform for their
merchant customers a variety of customer service related activities. NOVA ACS,
which was introduced in 1997, incorporates retrieval and chargeback information
as well as on-line statements. These enhancements give the ISO, bank or merchant
the opportunity to retrieve information on-line.

                                       11

   Cellular Digital Packet Data. Cellular Digital Packet Data, marketed under
the name "TRAVERSE," uses cellular airwaves, as opposed to traditional phone
lines, enabling wireless transaction authorization and processing. NOVA
currently has agreements with AT&T Wireless Services, GTE Corporation and Bell
Atlantic NYNEX Mobile to provide cellular transmission services. TRAVERSE
enables transaction authorization and processing in environments where
traditional phone lines are unavailable, inconvenient and/or prohibitively
expensive, affording merchants increased flexibility, mobility and security in
processing card transactions. Further, TRAVERSE allows merchants that have
relied on paper-based processing, where the ability to check if a card is stolen
or credit limits exceeded is generally unavailable or inconvenient, to convert
to electronic processing. In so doing, such merchants can also avoid the higher
rates imposed by each of VISA and MasterCard for paper-based transactions.

   NOVA WEBWAY. NOVA offers Internet services to merchant customers through an
agreement with Harbinger Corporation. NOVA WEBWAY is software designed to allow
merchants the opportunity to build a functional commerce-ready web-site complete
with up to a 99 page catalog. Using a wizard interface, NOVA WEBWAY prompts a
customer to describe its business, load product descriptions, pricing and
pictures and includes secure on-line ordering and encrypted credit card payment
capabilities. NOVA WEBWAY is a total web page solution at an attractive price
point specifically designed for small business. NOVA has several merchants using
this product.

   Internet Processing. NOVA is actively pursuing development initiatives
relating to transaction processing services on the Internet and other forms of
electronic commerce. NOVA is exploring with KeyBank and other third parties
several Internet-related opportunities, which include processing transactions
via the Internet, accepting merchant applications via the Internet and
developing, on behalf of merchants, ''home-pages'' on the Internet. In addition,
NOVA has entered into agreements with several companies which will provide to
NOVA encryption services (a security measure) for transactions processed via the
Internet. These Internet-related initiatives are still in formative stages and
security is the prevailing issue and concern. NOVA, however, is active in the
development process and management believes that the Internet may, ultimately,
become another distribution channel for NOVA's products and services.

   NOVA-PERKS.   NOVA Perks is a PC-based application that allows a subscribing
merchant to design and operate a customized frequent shopper program. This
program enables the merchant to promote sales and to track, store and retrieve
detailed information about its customers and all of their purchases regardless
of the method of payment. Merchants who do not use NOVA for transaction
processing services can still utilize NOVA-Perks.

Customer Base

   NOVA's merchant customer base consists primarily of small- to medium-sized
merchants, with a historic concentration in the restaurant, specialty retail,
furniture, automobile repair and lodging industries. In addition, banks also are
customers of NOVA insofar as those banks accept credit card cash advance
transactions. While NOVA's merchants vary significantly in size, a typical
merchant customer generates approximately $100,000 in annual charge volume.
Although NOVA focuses on small- to medium-sized merchants, NOVA also serves a
significant number of large merchants and has in place the technical,
operational and management infrastructure necessary to continue to serve large
merchants. For the years ended December 31, 1998, and 1997, no merchant customer
accounted for more than 2.5% of NOVA's revenues. At December 31, 1998, NOVA
provided transaction processing services to approximately 450,000 merchant
locations nationwide.

   NOVA enters into direct contractual relationships with its merchants, thereby
reducing NOVA's financial risks to NOVA in the event any of NOVA's bank alliance
partners no longer desire to utilize NOVA's services. In contrast to NOVA's
approach, the typical transaction processor/bank relationship involves a
processor negotiating with a bank to serve all of the bank's merchants, with the
bank maintaining direct control over each merchant relationship. Such a
structure exposes the processor to the risk that each of the merchant
relationships, and the revenues from those relationships, easily could be
jeopardized if, for example, the bank were to sell its merchant business
portfolio to an acquiror that provided its own transaction processing services.

                                       12

Marketing

   NOVA markets its services through three principal channels:

 .    bank alliances, including joint ventures, through which NOVA offers its
     services to merchants in cooperation with community and regional banks,
     allowing NOVA to capitalize on the presence of those banks in particular
     geographic markets;

 .    acquiring or partnering with ISOs that market and sell NOVA's services to
     merchants, typically in areas where NOVA does not have bank alliances; and

 .    direct sales on behalf of and as a supplement to the bank alliance and
     ISO partnering channels.

   In addition, NOVA engages in marketing efforts that include marketing
agreements with various trade and other associations and marketing through
value-added resellers that integrate NOVA's transaction processing services with
specialized business management software.  NOVA's investments in KMS and Elan
and its alliances and marketing relationships with Crestar Bank ("Crestar"),
MBNA and First Union are the most significant examples of marketing through bank
alliances.  Each of these relationships enhance significantly NOVA's ability to
further its market penetration and increase the size of its customer base
through the marketing assistance, support and exclusive merchant referrals
provided by the participating banks.

Bank Alliances

   NOVA's principal marketing efforts are directed at forming bank alliances.
During 1997 and 1998, NOVA entered into bank alliances with KeyBank, Firstar,
Crestar and MBNA in connection with joint venture or portfolio purchase
transactions with those banks. Through its relationships with its bank alliance
partners, NOVA offers its services to merchants in cooperation with community
and regional banks, allowing NOVA to capitalize on the presence of those banks
in particular geographic markets. NOVA's bank alliances consist of four types of
relationships:

 .    "Acquisition Alliances" consisting of relationships created as a result of
     NOVA's purchase of a bank's merchant portfolio, pursuant to which NOVA
     provides transaction processing services on a co-branded basis with such
     bank;

 .    "Joint Venture Alliances" consisting of relationships created through a
     joint venture, generally in the form of a limited liability company owned
     jointly by NOVA and a bank, pursuant to which NOVA provides transaction
     processing services and the bank provides marketing and referral services
     to the joint venture;

 .    "Agent Bank Alliances" consisting of agent bank relationships pursuant to
     which the bank purchases NOVA's services and markets and resells those
     services directly to merchants; and

 .    "Bank Referral Alliances"consisting of bank referral relationships where
     the bank refers to NOVA merchants who desire or otherwise inquire about
     transaction processing services.

   Pursuant to its Acquisition Alliances and Joint Venture Alliances, NOVA
offers banks the opportunity to transfer management and operational
responsibility for their merchant portfolios to NOVA either directly or through
the joint venture.  NOVA's Acquisition Alliance and Joint Venture Alliance
partners continue to offer transaction processing services on a co-branded basis
in cooperation with NOVA or the joint venture. In connection with Acquisition
Alliances and Joint Venture Alliances, NOVA or the joint venture may maintain
transaction processing salespersons on-site at the bank partner's branch
locations.  The salespersons service existing merchant customers and market and
sell NOVA's processing services to new merchant customers.  As a result of this
structure, NOVA can often effect a nondisruptive transition of services from the
merchants' perspective following the creation of the Acquisition or Joint
Venture Alliance.  To  facilitate this transition process and to assist its
Acquisition Alliance and 

                                       13
<PAGE>
 
Joint Venture Alliance partners, NOVA has created an intensive training program
whereby NOVA's personnel train and educate its Acquisition Alliance and Joint
Venture Alliance partners in all aspects of NOVA's transaction processing
services, software application products and value-added services.

   NOVA compensates its bank alliance partners through varying means. NOVA
typically compensates its Acquisition Alliance partners by remitting to them a
residual for each transaction that NOVA processes for merchants attributable to
the alliance.  NOVA compensates its Bank Referral Alliance partners typically by
paying them a one-time referral fee.  NOVA does not directly compensate its
Agent Bank Alliance partners as they derive revenue by reselling NOVA's services
to merchants at a price determined by the agent bank.

   NOVA has expanded its alliance efforts through a marketing agreement with
Kessler Financial Services L.P. ("Kessler"), an independent marketing
organization. Pursuant to this agreement, Kessler identifies potential alliance
or acquisition prospects for NOVA. NOVA's agreement with Kessler is scheduled to
expire June 30, 2001, subject to renewal for two additional years unless either
NOVA or Kessler gives notice of termination prior to the expiration of the
initial term.

   NOVA also employs a direct sales force that markets the services of NOVA on
behalf of NOVA's alliance, ISO and joint venture partners.  The internal sales
force includes a national account sales team that supports Acquisition Alliances
and Joint Venture Alliances in signing larger and more technologically
sophisticated merchants.

   ISO Partnering.  With the acquisition of the merchant portfolio of the Bank
of Boulder in December 1994, NOVA made its first significant entry into the ISO
marketing channel. NOVA significantly expanded its presence in this channel
through the PMT Merger. ISOs are entities that market NOVA's products in
conjunction with other products offered by the ISO, such as card readers and
related equipment. Generally, ISO partnering involves engaging an ISO to market
and sell NOVA's products and services on a non-exclusive basis. An ISO that
desires to refer a merchant customer to NOVA will procure the merchant's
application and submit it to NOVA on the merchant's behalf. Thereafter, if the
application is approved, the ISO will sell or lease point of sale terminals and
related hardware and software to such merchant. NOVA compensates ISOs by paying
them a residual for each transaction processed by NOVA for merchants referred to
NOVA by the ISO. The ISO's determination of whether to refer a particular
merchant to NOVA depends on a variety of factors, including the terms of the
residual offered by NOVA and the industry in which the merchant conducts its
business.

Association Marketing

   Through its association marketing program, NOVA negotiates and enters into
marketing agreements with various trade and other associations. Pursuant to
these relationships, associations endorse and promote to their membership the
transaction processing services provided by NOVA, creating additional
opportunities for NOVA to reach small- to medium-sized merchants. NOVA
currently has agreements with 300 associations. NOVA expects that its marketing
relationship with MBNA will expand NOVA's association marketing opportunities.

Other Marketing Efforts

   In addition to bank alliances, ISO partnering and direct sales and
telemarketing, NOVA engages in other marketing efforts that management believes
complement and diversify further NOVA's overall marketing strategy:

 .    Marketing Through Value-Added Resellers.  NOVA's marketing efforts are
     diversified further through the integration of its transaction processing
     services with the specialized business management software of a growing
     number of value-added resellers.  Value-added resellers perform a marketing
     function for NOVA since their software often is offered on a fully-
     integrated basis with NOVA's transaction processing 

                                       14
<PAGE>
 
     services, creating additional opportunities for NOVA to satisfy the
     particular needs of its merchant customers.

 .    Procurement and Purchasing Cards. Corporate procurement and purchasing
     cards are growing in popularity and flexibility of use, and NOVA is
     exploring opportunities intended to take advantage of this emergence.
     Although very similar in most respects to bank and charge cards,
     procurement and purchasing cards are tailored to a specific business and
     functionality. Purchasing cards may be used, for example, to replace the
     traditional use of paper-based purchase orders, confirmations and invoices
     with electronically authorized, processed and recorded transactions.
     Another illustrative use of a purchasing card is an insurance company that
     issues purchasing cards to its policy holders for the purchase of medical
     supplies, prescriptions and services from certain health care providers who
     have agreed in advance, to accept the insurance company's purchasing cards.

   NOVA periodically reviews its marketing efforts and distribution channels to
minimize channel conflict.  Although channel conflict among bank alliances,
ISO partnering and direct sales marketing may occur, to date NOVA has not
experienced any significant conflict while pursuing its overall sales strategy.

Acquisition Strategy

   The transaction processing industry has undergone rapid consolidation over
the last several years. The costs to convert from paper-based to electronic
processing, merchant requirements for improved customer service, and the demands
for additional customer applications have made it difficult for community and
regional banks and ISOs to remain competitive. Many of these providers are
unwilling or unable to invest the capital required to meet these demands, and
increasingly are exiting the transaction processing business or otherwise
seeking alliance partners to provide transaction processing for their customers.

   Since inception, NOVA has pursued an active acquisition strategy, including
the PMT Merger, the engaging in joint ventures and bank alliances.

   NOVA intends to continue to pursue purchases of merchant portfolios and the
formation of joint ventures and alliances with other financial institutions in
order to facilitate growth, expand NOVA's distribution channels and achieve
greater economies of scale. This strategy focuses on the merchant portfolios and
related assets of banks and ISOs that no longer desire or are unable to provide
efficient and cost-effective transaction processing services. NOVA attempts to
structure its acquisitions, joint ventures and alliances both to increase its
merchant base and to expand its distribution and marketing capabilities.

   NOVA continues to evaluate potential joint ventures and alliances and
purchases of merchant portfolios, and purchases of ISOs.  However except as
described in this Annual Report on Form 10-K, NOVA currently is not a party to
any agreements or understandings with respect to any such material purchases. In
addition, each of the First Union Alliance and the Crestar marketing
relationship may create additional purchase opportunities for NOVA, as NOVA and
each of First Union and Crestar have agreed that NOVA generally may, at its
option and subject to agreement on price and other terms, purchase from First
Union or Crestar any merchant portfolios purchased by First Union or Crestar
through whole-bank or other acquisitions. See ''--First Union Shareholders
Agreement.''  There can be no assurances as to the timing of such transactions.
There can be no assurance that the First Union Alliance or the Crestar marketing
relationship will provide future acquisition opportunities or that any such
acquisition opportunities can be completed on terms favorable to NOVA, if at
all.

Risk Management

   NOVA views its risk management and fraud avoidance practices as integral to
its operations and overall success because of NOVA's potential liability for
merchant fraud, charge-backs and other losses. Risk management and fraud
avoidance occur initially at the application stage when merchant applications
are reviewed against certain criteria to determine acceptance or denial. NOVA
utilizes various criteria to accept or deny applications and to determine the
rate structure charged, including a review of the applicant's credit history,
the industry in which the 

                                       15
<PAGE>
 
applicant conducts its business and various other relevant factors. In certain
instances, NOVA may require a guarantee or an escrow deposit as a condition to
approving an application or place a maximum volume limitation on transactions
processed.

   NOVA's principal advantage in its risk management and fraud avoidance
capabilities is the ability to run "Witness", its proprietary rule based fraud
detection software program against each transaction electronically processed on
the NOVA Network before funds are transferred to the merchant in payment for
such transaction. This ability is critical to NOVA's overall program to control
fraud and manage risk and is an example of NOVA's strategy of leveraging
available technologies, and the NOVA Network, to its competitive advantage.
Specifically, NOVA's Witness system consolidates files comprised of the day's
transaction activity, and transmits such information to its operations center in
Knoxville, Tennessee at or prior to the time it sends that information to the
merchant accounting vendors for merchant accounting. NOVA's Witness runs against
each of the day's transactions processed on the NOVA Network, resulting in a
computer-generated identification of potentially fraudulent activity. Once
identified, individuals analyze and review the suspect transactions to resolve
potential problems. This can be accomplished before funds are transferred to the
merchant in payment for such transactions. If NOVA needs more time to review a
transaction or series of transactions, however, NOVA can specify that the
batches containing the identified transactions be withheld from further
processing to allow additional time to attempt to verify the authenticity of
such transactions. Witness also allows NOVA to review certain types of
transactions on a real time basis. Consequently, NOVA has the ability to
intercept and review potentially fraudulent transactions and stop payment or
otherwise resolve them, as appropriate, prior to the time when financial
liability for such transactions has shifted to NOVA.

   Despite NOVA's risk management and fraud avoidance capabilities, NOVA is
unable to identify all fraudulent transactions resulting in financial exposure
to NOVA. Further, until NOVA converts each newly acquired merchant account to
NOVA's merchant accounting processors, NOVA is unable to apply fully its risk
management and fraud avoidance practices to such merchant accounts.

   In connection with portfolio purchases, NOVA reviews any merchant portfolio
that it proposes to purchase. The review process includes analyzing the
composition of the portfolio, applying uniform standards and underwriting
guidelines developed by NOVA to the portfolio and identifying any high-risk
merchants contained in the portfolio. Upon completion of this review, NOVA
determines whether the portfolio meets NOVA's standards and guidelines and is
otherwise a suitable acquisition target. If NOVA decides to proceed with the
proposed purchase, NOVA will focus on the high-risk merchants identified by its
review and attempt to manage the risk associated with such merchants. Typically,
NOVA will seek to exclude high-risk merchants from the portfolio purchase,
require the seller of the merchant portfolio to establish a reserve account or
require the seller of the merchant portfolio to indemnify NOVA for any liability
associated with such merchants. The experience accumulated by NOVA during the
course of its purchases is constantly drawn upon to refine NOVA's due diligence
procedures and practices, and management expects to continue to improve its due
diligence efforts.  Nevertheless, the Company can give no assurance that its due
diligence process will identify all high-risk merchants or that NOVA will
otherwise assess properly the risk attributes of any purchased portfolio.

Merchant Accounting and Clearing Bank Relationships

   NOVA relies upon third parties vendors to provide merchant accounting and
clearing bank services to NOVA and its merchant customers. In each of these
instances, NOVA has engaged multiple providers to safeguard against the loss of
services or quality of any one of these providers.

   Merchant Accounting.   Merchant accounting services consist of reorganizing
and accumulating daily transaction data on a merchant-by-merchant and card
issuer-by-card issuer basis, and forwarding this data to the credit card
associations for ultimate payment. These services are provided by our merchant 
accounting vendors. We are also currently developing internal systems to provide
our own merchant accounting services beginning in 1999.

                                       16
<PAGE>
 
   Clearing Bank Arrangements.   NOVA's clearing banks receive payment for
merchant transactions from credit card associations (net of fees payable to the
credit card associations and card issuing banks), from which the clearing banks
remit payment to the merchant for the gross amount of the merchant's
transactions. Once each month, NOVA collects applicable merchant discount and
other fees from each merchant for transactions effected and services provided
during the preceding month. NOVA, along with all other nonbank transaction
processors that process VISA and MasterCard transactions, must be sponsored by a
financial institution that is a principal member of the VISA and MasterCard
credit card associations in order to process these bankcard transactions.
Through each of Regions Bank, Bank of the West, Imperial Bank, FNBO, Zions
Bank, Firstar, KeyBank and FUNB, which serve as member clearing banks for NOVA,
NOVA is registered with VISA and MasterCard as a certified processor and member
service provider. While NOVA's registration as a certified processor and member
service provider is necessary in order for NOVA to process VISA and MasterCard
transactions, management believes that the revocation of such registrations is
unlikely and inconsistent to the objectives of both the credit card associations
and the clearing banks because of the adverse effect such action would have on
the continuity of credit card acceptance.

   NOVA's agreements with its principal member clearing banks generally provide
that the merchant relationship is controlled by NOVA. Accordingly, NOVA
generally is not obligated to continue to utilize the clearing services of these
banks, and may transfer the clearing functions to another principal member
clearing bank (i.e., any member of the VISA and MasterCard associations),
although there can be no assurance that NOVA would be able to find a financial
institution to sponsor it on terms acceptable to NOVA.

   Effective May 1, 1997, MasterCard approved changes to its Member Service
Provider ("MSP") rules to, among other things, differentiate between ISOs
which perform merchant and cardholder services and third party processors
("TPPs"), such as NOVA.  The new MSP rules implement a Processor Certification
Program requiring NOVA and other TPPs to register as a TPP with MasterCard. NOVA
is currently registrated as a "Type II" TPP. With the PMT Merger, NOVA now
believes it can satisfy certain criteria including requirements as to the number
of merchant accounts serviced, processing volume and concentration of risk for
"Type I" TPP registration and has initiated the registration process. All Type I
TPPs must undergo annual reviews by MasterCard, including a review of processing
performance, authorization host availability, authorization response time and
call referral merchant response. Type I TPPs also must be financially sound and
maintain adequate financial resources.   The benefits to participating as a Type
I TPP are representation in the certification group program, eligibility for
MasterCard's Annual Certification, monthly benchmarking reports accessibility,
operational support, and support in implementing performance improvement
programs.

Customer Service and Support

   NOVA is dedicated to providing reliable and effective customer service and
support to its merchant customers. The information access and retrieval
capabilities of the NOVA Network, where real-time information is available to
NOVA's customer service representatives, allow NOVA to provide a level of
customer service and support to small- to medium-sized merchants historically
available only to much larger merchants. For example, any of NOVA's customer
service representatives may access, on a real-time basis, all of the relevant
information pertaining to any particular merchant that may call and ask for
assistance. NOVA also has implemented an on-line, informational database that
provides NOVA's customer service representatives user-friendly access to an
array of additional information relative to NOVA's services, products and
systems, which often allows NOVA to more quickly and effectively resolve
customer service inquiries.

   NOVA maintains a 24-hours-a-day, seven-days-a-week helpline at its operations
center in Knoxville, Tennessee. NOVA measures the efficiency of its customer
service through certain quantitative data such as the number of rings prior to
operator pick-up, the number of abandoned calls, the number of calls per day and
the number of calls per customer service representative. NOVA has developed
comprehensive programs and procedures for training its approximately 250 full-
time customer service representatives to assist NOVA's merchant clients in a
timely and efficient manner with any problems, issues or concerns they may have.
Management is dedicated to providing outstanding customer service and support
and continually reviews its policies and procedures in an effort to improve
these services.

                                       17

Proprietary Rights

   NOVA has developed proprietary software for use in four principal areas: (i)
applications for POS terminals and PCs; (ii) transaction switching; (iii) the
NOVA Network; and (iv) customer service and charge-backs. NOVA regards its
proprietary software as protected by trade secret and copyright laws of general
applicability. NOVA attempts to safeguard its software through the protection
afforded by the above-referenced laws, employee and third-party non-disclosure
agreements, licensing agreements and other methods of protection. Despite these
precautions, it may be possible for unauthorized third parties to copy, obtain
or reverse engineer certain portions of NOVA's software or to otherwise obtain
or use other information NOVA regards as proprietary. While NOVA's competitive
position may be affected by its ability to protect its software and other
proprietary information, management believes that the protection afforded by
trade secret and copyright laws are less significant to NOVA's success than
other factors such as the knowledge, ability and experience of NOVA's personnel
and the continued pursuit and implementation of its operating strategies.

   As the number of software application products in the transaction processing
industry increases, and as the functionality of such products further overlaps,
third parties could assert that NOVA's software application products infringe or
may infringe the proprietary rights of such entities. These third parties may
seek damages from NOVA as a result of such alleged infringement, demand that
NOVA license certain proprietary rights from them or otherwise demand that NOVA
cease and desist from its use and/or license of the allegedly infringing
software. Although management is not currently aware of any alleged infringement
issues, any such action, if it were to occur, may result in protracted and
costly litigation or royalty arrangements or otherwise have a material adverse
effect on NOVA's financial condition and results of operations.

   NOVA currently licenses certain software from third parties to supplement its
internal software and technology development and to shorten time-to-market
software application product deliveries. For instance, NOVA licenses the
software for NOVA Time. Management believes that it will be necessary to
continue this practice in the future, although there can be no assurance that
NOVA will be able to do so on favorable terms or at all.

   NOVA's servicemarks include INNRESPONSE, INNSYNCHRA MASS TRANSACT, NOVA, NOVA
Information Systems, NOVA-PERKS, NOVA ACS, NOVA REMOTE ACS, NOVA CLOCK, NOVA
ENCOMPASS, NOVA GRATUIT, NOVALODGE, NOVA SHADOW PAY, NOVA TIME, NOVA TRANSPORT,
NOVA WEBWAY, ON-SET, PC TRANSACT_IT, POS CONTROL, TRAVERSE. To date, however, 
NOVA only has sought to have "NOVA," "NOVA-PERKS" AND ON-SET registered with the
U.S. Patent and Trademark Office ("PTO"). NOVA's application to register "NOVA"
was refused and allowed to lapse without contesting the refusal. NOVA-PERKS is 
registered with the PTO, and the application for ON-SET is currently pending.

Competition and Consolidation

   The market for providing credit, charge and debit card transaction processing
services to the small- to medium-sized merchant segment served by NOVA is highly
competitive. The level of competitiveness has increased significantly since
NOVA's inception and this trend is expected to continue. NOVA competes in this
market segment on the basis of price, the availability of related products and
services, the quality of customer service and support, and transaction
processing speed, quality and reliability. NOVA's principal competitors in this
market segment include other smaller vertically integrated processors, community
and regional banks and ISOs and, increasingly, the ten largest bankcard
processors. Several of NOVA's competitors and potential competitors have greater
financial, technological, marketing and personnel resources than NOVA, and there
can be no assurance that NOVA will continue to be able to compete successfully
with such entities. In addition, the competitive pricing pressures that would
result from any increase in competition would adversely affect NOVA's margins
and may have a material adverse effect on NOVA's financial condition and results
of operations.

   According to industry sources, the ten largest bankcard processors accounted
for approximately 69% of the total charge volume processed in 1997, the latest
year for which statistics are avilable. The largest bankcard processor accounted
for approximately 16% of the total charge volume processed in 1998.

                                       18
<PAGE>
 
   NOVA believes that it has reached a sufficient size whereby economies of
scale allow it to offer competitive pricing. However, certain of NOVA's
competitors may have lower costs which could potentially give them an advantage.
As a result of its experience in payment processing, NOVA has been able to
develop operating efficiencies that NOVA believes allow it to competitively bid
for new business. In addition, NOVA has continually made technological
improvements and is thus able to respond to the unique needs of merchants in
various industries. Management believes that the quality, speed and reliability
of the NOVA Network and the breadth, flexibility and user-friendliness of its
software application products and services constitute a competitive advantage.
NOVA intends to maintain its strategy of focusing on small- to medium-sized
merchants because management believes this market segment is somewhat less price
sensitive than larger accounts.

   NOVA faces increasing competition from other transaction processors for
available acquisition opportunities. In addition, community and regional banks,
which serve as a marketing channel for NOVA's services and whose transaction
processing businesses have been NOVA's primary source of acquisition
opportunities, have been undergoing extensive consolidation reflective of
underlying trends in the financial institutions industry and unrelated to their
transaction processing businesses. As a result, smaller banks that may have
sought to divest themselves of their transaction processing businesses may be
acquired by banks that compete with NOVA or banks that have a relationship or
alliance with one or more competitors of NOVA, thus potentially depriving NOVA
of distribution channels and/or acquisition opportunities.

Banking Regulation

   As a result of First Union's ownership interest in NOVA, NOVA has become
subject to certain banking laws, regulations and orders (collectively, the
"Banking Laws"). For example, NOVA is now subject to the supervision and
examination of the Office of the Comptroller of the Currency (the "OCC"), one
of the principal banking regulatory bodies (although management does not believe
it is likely that the OCC would ever exercise this supervisory and examination
authority). In addition, the OCC reviewed extensively the KMS joint venture, the
First Union Alliance and the Elan joint venture and the terms thereof, and the
OCC's written approval was required in order to consummate those transactions.
To facilitate First Union's compliance with the Banking Laws, and to allow First
Union to obtain any required consents or approvals, NOVA has agreed to notify,
and obtain approval from, First Union before NOVA enters into any business
activities substantially different from the business activities NOVA currently
conducts. Pursuant to the KMS joint venture and the Elan joint venture and to
the extent required by the Banking Laws, NOVA may be required to take certain
measures in the event either NOVA or the limited liability companies formed
pursuant to the transactions enters into or acquires any other entity which is
engaged in a business that is substantially different from the business
activities NOVA, or the limited liability companies, currently conduct. Such
measures may include applying for any required regulatory consents, or assisting
either KeyBank, Firstar, or the limited liability companies, as the case may be,
to prepare such applications. If the required consents and approvals are not
received, NOVA may not engage in the new business activity.

Employees

   At February 28, 1999, NOVA had 1,812 full-time employees, and 23 part-time
employees. None of NOVA's employees are represented by a collective bargaining
agreement nor has NOVA ever experienced any work stoppage. Management believes
that NOVA's relationship with its employees is good.

   In December 1998, NOVA accelerated its conversion and consolidation of the
operations of its PMT  and its subsidiaries into NOVA's operations.  As part of
this consolidation, NOVA is moving PMT's Nashville, Tennessee operations to
NOVA's existing facilities in Atlanta, Georgia and Knoxville, Tennessee.  NOVA
anticipates that the consolidation will result in a reduction in work force of
approximately 275 employees.

Certain Risks Associated with the Business of the Company

   In addition to the risks and other considerations discussed elsewhere in this
report, set forth below is a discussion of certain risk factors relating to the
Company's business and operations.  These risk factors are drafted in "Plain
English" format in accordance with Rule 421 of the Securities Act. Accordingly, 
references to "we" and "our" refer to NOVA and its subsidiaries.

Our Dependence upon VISA and MasterCard Registration and Financial Institution
Sponsors

   We must be sponsored by a financial institution that is a principal member of
the VISA and MasterCard credit card associations in order to process bankcard
transactions.  Our designation with VISA and MasterCard as a certified processor
and our status as a member service provider are dependent upon the sponsorship
of member clearing banks and our continuing adherence to the standards of the
VISA and MasterCard credit card associations.  The member financial institutions
of VISA and MasterCard set these standards.  Some of the member financial
institutions of VISA and MasterCard provide transaction processing services in
direct competition with our services.  In the event we fail to comply with these
standards, VISA or MasterCard could suspend or terminate our designation as a
certified processor or our status as a member service provider.  The termination
of our member service provider registration or our status as a certified
processor, or any changes in the VISA or MasterCard rules that prevent our
registration or otherwise limit our ability to provide transaction processing
and marketing services for VISA or MasterCard, would have a material adverse
effect on our business, financial condition and results of operations.  See
"Business--Merchant Accounting and Clearing Bank Relationships."

Risks Associated with Our Merger and Acquisition Strategy

Increased Consolidation in the Marketplace Has an Impact on Price and
Availability of Acquisition, Joint Venture and Alliance Opportunities

   Historically, our growth strategy has been materially dependent upon the
purchase of additional merchant portfolios and acquisition of operating
businesses and transaction processing assets. We face significant competition
from other transaction processors for available acquisition, joint venture and
alliance opportunities. This competition has an impact NOVA's ability to
consummate of acquisitions, joint ventures and alliances on acceptable terms. In
addition, in recent years community and regional banks, whose transaction
processing businesses have been our primary source of acquisition opportunities,
have undergone extensive consolidation unrelated to their transaction processing
businesses. As a result, our financial institution competitors or financial
institutions that have a relationship or alliance with one or more of our
competitors may acquire smaller banks that may have sought to divest themselves
of their transaction processing businesses. These acquisitions potentially
deprive us of acquisition opportunities. We cannot give any assurances that the
historical or current level of acquisition opportunities will continue to exist,
that we will be able to acquire merchant portfolios, operating businesses and
transaction processing assets that satisfy our criteria, or that any such
transaction will be on favorable terms.

We May Be Unable to Accurately Analyze Risks Associated with Purchased Merchant
Portfolios, Joint Ventures or Business Combinations

   When we evaluate a potential purchase of a merchant portfolio, joint venture
or business combination, we conduct a due diligence review of the related
merchant portfolio.  The review process includes analyzing the composition of
the merchant portfolio, applying our uniform standards and underwriting
guidelines to the merchant portfolio and attempting to identify high-risk
merchants included in the merchant portfolio.  Notwithstanding these due
diligence efforts, however, it is not possible to properly assess all of the
risk attributes associated with a purchased or otherwise acquired portfolio or
otherwise identify all of the high-risk merchants.  Incorrect risk assessments
of our purchased or otherwise acquired portfolios may result in excessive losses
from chargebacks or merchant fraud.  See "Business--Risk Management."

We May Experience Higher than Anticipated Costs and Expenses in the Event of
Delays in the Conversion of Merchant Portfolios to Our Network

   At the time of consummation of merchant portfolio purchases, business
combinations or joint ventures, merchants in a purchased portfolio typically are
not operating on the NOVA Network and may not use the same merchant accounting
processors that we use.  Until we convert each newly-purchased merchant to the
NOVA Network and our merchant accounting processors:

                                       20
<PAGE>
 
 .    we do not fully realize the anticipated cost savings and synergies from the
     portfolio purchase, business combination or joint venture;

 .    we have little, if any, control over the performance of the other networks
     and processors;

 .    we typically are not able to apply fully our risk management and fraud
     avoidance practices to these merchants; and

 .    we must continue to pay third parties for processing services, which
     reduces our economic benefits in the merchant portfolio.

   In certain circumstances, third party processors may claim an ownership
interest in certain of the purchased merchant relationships to which they are
party.  If those claims are successful, they could impede the conversion and,
correspondingly, reduce the cost savings and synergies anticipated to be gained
by virtue of the purchased or otherwise acquired portfolio.

   As a result of our acquisition of PMT, our purchase of the CoreStates
merchant portfolio the KMS joint venture, and other smaller acquisitions, the
magnitude, scope, timing, duration and expense of the conversion of the PMT,
CoreStates and KeyBank and other merchant portfolios will, in the aggregate, be
greater than any conversion that we have previously undertaken. Our failure to
complete these conversions in accordance with management plans could have a
material adverse effect on our financial condition and results of operations.
See "Business--Significant Joint Ventures, Alliances and Marketing
Arrangements."

Our Acquisition Strategy Will Require Substantial Capital Resources and
Additional Indebtedness

   Our acquisition strategy will require substantial capital resources, and is
likely to result in the need for additional indebtedness.  We cannot give any
assurances that we will be able to obtain financing for future acquisitions on
favorable terms.

Risks Associated with Joint Venture Alliances

The Success of Our Joint Ventures Is Dependent Upon the Continued Cooperation of
Our Joint Venture Partners

   The Elan joint venture and the KMS joint venture involved the creation of a
newly-formed limited liability company that we jointly own, manage and service
with Firstar or KeyBank, as the case may be.  As a result, our continued
cooperation with each of Firstar and KeyBank is important to the success of the
joint ventures.  We cannot give any assurance that our relationship with either
Firstar or KeyBank will continue to be cooperative and, accordingly, there can
be no assurance that we will realize the anticipated economic benefits from the
joint ventures.  Further, the management and provision of processing services to
each of the joint ventures imposes increased administrative, managerial and
technological demands on our infrastructure and related systems, and there can
be no assurance that we will meet successfully such material demands and
requirements.  See "--Continued Consolidation in the Banking Industry May
Adversely Affect Our Marketing Channels."

Termination of Our Joint Ventures with Firstar and KeyBank Could Have an Adverse
Impact on Our Financial Condition and Results of Operations

   Our joint ventures with Firstar and KeyBank were formed for definitive terms
subject in each case to renewal provisions, but are subject to earlier
termination by us or Firstar or KeyBank under a variety of circumstances. In the
event of early termination, or upon termination of either joint venture upon
expiration of its term, the then-current assets and merchant portfolio of the
terminated joint venture are subject to "repurchase rights" by either us or
Firstar or KeyBank depending on the circumstances of termination.  For example,
each of the joint ventures imposes upon us certain standards with respect to the
performance of our processing services.  In the event we 

                                       21
<PAGE>
 
breach these standards and do not cure the breach, Firstar or KeyBank, as the
case may be, would have the right to purchase our interest in the respective
joint venture. If either Firstar or KeyBank purchases our interest in the
respective joint venture, we would experience a significant decrease in the
number of merchant locations that we serve and the aggregate sales volume that
we process. This type of decrease could have a material adverse effect on our
financial condition and results of operations. Further, when we evaluated the
joint ventures, and established a purchase price in connection with our
investment in the joint ventures, we assumed the continuance of each of the
joint ventures for a minimum term. We may not realize the anticipated economic
and marketing benefits from the joint ventures in the event one or both is
terminated early.

High Levels of Competition May Have a Material Adverse Effect on Our Business,
Financial Condition and Results of Operations

   The credit, charge and debit card transaction processing services business is
highly competitive.  The level of competition has increased significantly in
recent years and we expect this trend to continue.  Several of our competitors
and potential competitors have greater financial, technological, marketing and
personnel resources, and we are uncertain whether we will continue to be able to
compete successfully with such entities.  In addition, our profit margins could
decline because of competitive pricing pressures that may have a material
adverse effect on our business, financial condition and results of operations.

Continued Consolidation in the Banking Industry May Adversely Affect Our
Marketing Channels

   We market our services through several different marketing channels,
including through our joint ventures and alliances with banks.  In the event
that there is continued significant consolidation in the banking industry, banks
that market our services through joint ventures, alliance relationships, and
otherwise may be acquired by banks with which we compete or by banks that have a
relationship or alliance with one or more of our competitors, thus potentially
depriving is of a distribution channel.  For instance, each of Firstar and
Crestar Bank, with whom we have an alliance relationship, recently engaged in a
business combination transaction with a third party financial institution.
While we do not believe that these business combinations will have a material
adverse effect on our relationship with either Firstar or Crestar, we are not
certain that the resulting entities in such business combinations will support
our respective relationships in the same manner and to the same degree as their
predecessors.  See "Business--Significant Joint Ventures, Alliances and
Marketing Arrangements."

Increased Merchant Attrition May Have a Material Adverse Effect on Our Business,
Financial Condition and Results of Operations

   We experience attrition in our merchant base in the ordinary course of
business resulting from several factors, including business closures, losses to
competitors and conversion-related losses.  In addition, substantially all of
our contracts with merchants may be terminated by us or the merchant upon prior
notice of 30 days or less.  Increased merchant attrition may have a material
adverse effect on our financial condition and results of operations.  We cannot
give any assurances that we will not experience higher rates of merchant
attrition in the future, particularly in connection with purchased merchant
portfolios and the acquisition of PMT.

We Are Dependent on Our Merchant Accounting Relationships with Third Parties

   We outsource certain merchant accounting services to our merchant accounting
vendors. These services consist of reorganizing and accumulating daily
transaction data on a merchant-by-merchant and card issuer-by-card issuer basis,
and forwarding this data to the credit card associations for ultimate payment.
If our Merchant Accounting Vendors do not continue to perform these services
efficiently and effectively, our relationships with our merchant customers may
be adversely affected and merchants may terminate their processing agreements.
We currently are developing internal systems to provide our own merchant
accounting services, and began to pilot these systems with 20,000 merchants in
1999. However, if our Merchant Accounting Vendors terminate their agreements
with us prior to completion and implementation of our internal systems, we would
have to seek alternative outsourcing arrangements to provide these merchant
accounting services. We are not certain whether we could locate alternative
outsourcing arrangements on terms as favorable to us as the existing contracts.

                                       22
<PAGE>
 
Accordingly, termination of the agreement with any merchant accounting vendor
could have a material adverse effect on our business, financial condition and
results of operations.

Increases in Interchange Rates May Adversely Affect Our Profitability

   VISA and MasterCard have increased their respective interchange rates each
year.  Although we historically have reflected these increases in our pricing to
merchants, there can be no assurance that merchants will continue to assume the
entire impact of the future increases or that transaction processing volumes and
merchant attrition will not be adversely affected by the increases.

Increases in Chargebacks May Adversely Affect Our Profitability

   When a billing dispute between a cardholder and a merchant is resolved in
favor of the cardholder, the transaction is "charged back" to the merchant and
the amount of the transaction is credited to the cardholder.  Reasons for
billing disputes include, among others:

 .  nonreceipt of merchandise or services;

 .  unauthorized use of a credit card; and

 .  quality of the goods sold or the services rendered by that merchant.

   If we or our clearing banks are not able to collect chargeback amounts from a
merchant's account, or if the merchant refuses or is not able due to bankruptcy
or other reasons to reimburse us for the chargeback, we bear the loss for the
amount of the refund paid to the cardholder.  We attempt to reduce our exposure
to such losses by performing periodic credit reviews on our merchant customers
and adjusting rates based, in part, on the merchant's credit risk, business or
industry.  However, we cannot give any assurances that we will not experience
significant losses from chargebacks in the future.  Increases in chargebacks not
paid by merchants may have a material adverse effect on our business, financial
condition and results of operations.  See "Business--Risk Management."

We Bear the Risk of Fraud Committed by Our Merchant Customers

   We bear the risk of losses caused by fraudulent credit card transactions
initiated by our  merchant customers.  Examples of merchant fraud include
inputting false sales transactions or false credits.  We monitor merchant
transactions against a series of standards developed to detect merchant fraud.
Despite our efforts to detect merchant fraud, it is possible that we will
experience significant amounts of merchant fraud in the future, which may have a
material adverse effect on our business, financial condition and results of
operations.  See "Business--Risk Management" and "Business--Customer Base."

We Are Dependent Upon MCI WorldCom for Telecommunications Services

   Our proprietary telecommunications network, the NOVA Network, is a critical
component of our transaction processing services. MCI WorldCom provides to us
long-distance and local telecommunications access and technical support for the
NOVA Network.  This agreement expires July 1, 2001, although we have the right
to terminate the agreement earlier in the event of quality deficiencies in MCI
WorldCom's service.  If the agreement is terminated or not renewed, we would be
required to utilize the long-distance and local telecommunications access of
another long-distance provider, which may increase our expenses for network
services, resulting in a material adverse effect on our financial condition and
results of operations.  MCI WorldCom owns approximately 2.6% of the outstanding
common stock and has a representative on our Board of Directors. It is possible
that conflicts of interests between MCI WorldCom and NOVA will arise and that
such conflicts may not be resolved in a manner favorable to us.  See "Business--
Technology."

                                       23
<PAGE>
 
We May Become Subject to Certain State Taxes That Currently Are Not Passed
through to Our Merchants

   We, like other transaction processing companies, may be subject to state
taxation of certain portions of our fees charged to merchants for our services.
Application of this tax is an emerging issue in the transaction processing
industry and the states have not yet adopted uniform guidelines.  If we are
required to pay such taxes and are not able to pass this tax expense through to
our merchant customers, our financial condition and results of operations could
be adversely affected. 

We Must Continue to Update and Develop Technological Capabilities and New
Products in Order to Compete

   Because the transaction processing industry and the software application
products and value-added services of the type that we offer have been
characterized by rapidly changing technology and the development of new products
and services, we believe that our future success will depend, in part, on our
ability to continue to improve our products and services and to offer our
merchant customers new products and services.  We cannot give any assurances
that we will continue to develop successful new products and services or that
our newly-developed products and services will perform satisfactorily or be
widely accepted in the marketplace.  See "Business--Software Application
Products and Value Added Services."

We Experience Fluctuations in Our Quarterly Operating Results

   We have experienced and expect to continue to experience significant
seasonality in our business resulting in fluctuations in our quarterly operating
results.  We typically realize higher revenues in the third 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.  The timing
of purchases of merchant portfolios and joint ventures and the  timing and
magnitude of expenses for merchant portfolio conversions also affect our
quarterly results.  Fluctuations in operating results may result in volatility
in the price of our common stock.

Our Need to Retain the Services of Mr. Grzedzinski

   Our success depends largely on the efforts and skills of our executive
officers and key employees, particularly Edward Grzedzinski.  The loss of the
services of one or more of these persons could materially adversely affect our
business, financial condition and results of operations.  We have entered into
employment agreements with Mr. Grzedzinski and other members of management.



A Significant Portion of Our Assets Consists of Intangible Assets

   A substantial portion of our assets are intangible assets related to
purchased merchant portfolios or business operations. In the event of a material
decline in revenues generated from any of our purchased merchant portfolios or
business operations that reduces the fair value of the portfolio or operations,
we would be required to reduce the carrying value of the related intangible
asset. Additionally, changes in accounting policies or rules that affect the way
in which we reflect these intangible assets in our financial statements, or the
way in which we treat the assets for tax purposes, could have a material adverse
effect on our financial condition.

Agreements Limit Our Ability to Engage in Other Businesses and Impose
Territorial Restrictions

   In connection with the First Union Alliance, we agreed to notify and to
obtain approval from First Union before we enter into any business activities
substantially different from the business activities we currently conduct.
Likewise, our joint venture agreements with Firstar and KeyBank provide that, to
the extent required by applicable banking laws and regulations, we may be
required to take certain measures in the event we or the joint ventures enter
into or acquire any other entity which is engaged in a business that is
substantially different from our current 

                                       24
<PAGE>
 
business activities. These measures may include applying for any required
regulatory consents, or assisting either KeyBank, Firstar, or our joint ventures
in preparing the required applications. If the bank regulatory authorities do
not grant the required consents and approvals, we may not engage in the new
business activity.

   In connection with the First Union Alliance, our purchase of the merchant
portfolio of Crestar Bank and our joint ventures with Firstar and KeyBank, we
agreed that we will not, without the prior consent of the affected entity, enter
into certain marketing or, in certain instances, acquisition or purchase
agreements with third parties located in specified geographic areas where, as of
the date of such transactions, any of First Union, Crestar, Firstar or KeyBank
maintain a significant banking presence. The effect of these territorial
restrictions is to limit in certain respects our ability to directly seek or
take advantage of certain business or marketing opportunities other than through
a venture with our regional bank partners. The agreements generally do not
prohibit us from pursuing transactions indirectly through the respective
alliance or joint venture.

Our Articles of Incorporation May Inhibit a Takeover of NOVA

   Our Articles of Incorporation permit the Board of Directors to issue up to
5,000,000 shares of preferred stock with such designations, powers, preferences
and rights as it determines, without any further vote or action by our
shareholders.  The issuance of preferred stock could discourage bids for the
outstanding shares of common stock at a premium and have a material adverse
effect on the market price of the common stock.

   Three of Our Shareholders and Our Directors and Executive Officers Own or
Control a Significant Amount of Our Common Stock and Could, Therefore, Influence
Our Affairs

   As of March 29, 1999, Warburg, Pincus Investors L.P. and its affiliates
("Warburg"), First Union, MCI WorldCom and the executive officers and directors
of NOVA own beneficially an aggregate of 24.9% of NOVA's outstanding common
stock.  As a result of such stock ownership, these shareholders, if acting
together or in certain combinations, would be able to exert influence on matters
requiring approval by our shareholders, including the election of directors.

The Price of Our Common Stock Has Been Volatile and Could Continue to Fluctuate
Substantially

   Our common stock is traded on the New York Stock Exchange.  Since our initial
public offering in May 1996, there has been and may continue to be significant
volatility in the market for the common stock, based on a variety of factors,
including the following:

 .  future announcements concerning us or our competitors;

 .  changes in quarterly operating results;

 .  the gain or loss of significant contracts;

 .  the entry of new competitors into our markets;

 .  changes in management;

 .  announcements of technological innovations or new products by us or our
   competitors; and

 .  other events and circumstances some of which are beyond our control.

Future Sales of Our Common Stock Could Cause the Price of Our Shares to Decline

   Sales of a substantial number of shares of our common stock in the public
market could cause the price of the common stock to decline and could impair our
ability to raise equity capital. As of March 29, 1999, we have outstanding
approximately 72,819,789 shares of common stock. An additional 8,318,696
shares of common 

                                       25
<PAGE>
 
stock that may be issued in the future upon exercise of options granted and to
be granted under our stock option plans have been registered under the
Securities Act and therefore will be freely tradeable when issued, subject to
the volume and certain other conditions of Rule 144 promulgated under the
Securities Act in the case of shares to be sold by our affiliates. Options and
warrants for the purchase of approximately 6,559,769 shares of common stock
were outstanding as of March 29, 1999, of which, options and warrants for
2,758,699 shares were exercisable.

ITEM 2.   PROPERTIES

NOVA's principal executive offices are located in Atlanta, Georgia and consist 
of approximately 38,000 square feet that are leased pursuant to an agreement 
scheduled to expire November 30, 2001. All facilities are used primarily for 
administrative, sales and marketing, and operational functions. The following 
table describes the principal facilities being used in connection with NOVA's 
operations:

                               Approximate
Properties                     Square Footage        Lease/Own     Location

Sales Center                       29,000              Lease       Dunwoody, GA
Operations Center*                140,000              Own         Knoxville, TN
PMT Corporate Offices**           100,000              Lease       Nashville, TN

The Company also occupies other leased properties totaling approximately 90,000 
square feet in various locations to support sales and operations.

- ---------
  * The operations centers consist of 140,000 square feet in two primary
    buildings. The original 26,000 square foot facility is leased pursuant to a
    sublease agreement scheduled to expire September 1, 2003. NOVA expanded
    into its new 84,000 square foot operations center during the third quarter
    of 1998. This facility is part of the 112,000 square foot building that was
    purchased during 1998. The remaining 28,000 will be reserved for future
    expansion or sub-lease to third parties.

 ** The corporate offices were the headquarters of PMT prior to the PMT Merger.
    As part of the consolidation plans initiated in the fourth quarter of 1998,
    the facility will be vacated and sublease tenants sought under a term lease
    agreements.

NOVA believes that its facilities are suitable and adequate for its business 
needs for the foreseeable future.

ITEM 3.   LEGAL PROCEEDINGS

   NOVA has been involved from time to time in litigation in the normal course
of its business. While management is aware of and dealing with certain pending
or threatened litigation, management does not believe that such matters,
individually or in the aggregate, will have a material adverse effect on the
financial condition of NOVA.

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 the
fourth 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,
                                       27
<PAGE>
 
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.

Significant Developments

   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 ISO's 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 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 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 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.

                                       28
<PAGE>
 
The CoreStates portfolio added geographical diversity and strength to NOVA's
merchant customer base through the portfolio's approximately $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, ISO's, and other organizations that express to MBNA an
interest in merchant processing services. The MBNA portfolio contributed
approximately $1.1 billion in annualized credi t and debit card processing
volume in 1998.

Prior to the PMT Merger and since fiscal 1997, PMT completed three significant
merger transactions with ISO's: 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. 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 ISO's, 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 

                                       29
<PAGE>
 
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 joint venture and the KMS joint venture.
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 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 a percentage of
revenue increased to 77.3% from 76.3% because a substantial portion of the
volume from recent portfolio purchases and merger and acquisitions 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 of portfolios relating to the KMS
joint venture and the Elan joint venture, and the MBNA and CoreStates merchant
portfolios. Conversion activity for 1999 is expected to exceed 1998 levels due 
to the significance 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 of consolidation
activities.

After consideration of these charges, other selling, general and administrative
expenses 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 into the NOVA Network transition.

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


                                       31
<PAGE>
 
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. The remaining employees will leave NOVA during the first quarter of
1999. NOVA began the process of moving PMT's 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 merger and consolidation 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.

(1)  Represents reserve balances of $35.0 million at October 31, 1998, for PMT.
     Approximately $15.8 million of these reserves were paid as of February 19,
     1999.


Future cash outlays are anticipated to be completed by the end of 1999,
excluding certain lease commitments that will continue through August 2007 if
the Company is unable to sublease this space.

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.

<PAGE>
 
Minority Interest in Income of Subsidiaries

Minority interest in income of subsidiaries increased to $10.1 million in 1998
from $800,000 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 significant 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.

                                       34
<PAGE>
 
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 $206.1 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.

NOVA produces significant cash flow from operating activities, amounting to
$33.0 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

                                       35
<PAGE>
 
effect of depreciation and amortization and, for 1998, the non-cash portion of
the merger and consolidation charge.  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 $99.3 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 credit facilities of $80 million which are expandable to $100
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 waiver 
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.  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 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 

                                       36
<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 validation and correction of merchant
terminals for 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 an adverse material 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.

   Certain information required by Part III is omitted from this report but is
incorporated herein by reference to NOVA's definitive Proxy Statement for the
1999 Annual Meeting of Shareholders (the ''Proxy Statement''). Such Proxy
Statement will be filed with the Securities and Exchange Commission no later
than 120 days after December 31, 1998.


ITEM 10.   DIRECTORS AND EXECUTIVE OFFICERS OF THE REGISTRANT

   In accordance with General Instruction G(3) of the Form 10-K, the information
relating to the directors of NOVA, including directors who are executive
officers of NOVA, is set forth under the caption ''Proposal 1--Election of
Directors'' in the Proxy Statement and is incorporated herein by reference.
Pursuant to Instruction 3 of Item 401(b) of Regulation S-K and General
Instruction G(3) of Form 10-K, information relating to the executive officers of
NOVA is set forth under the caption ''Executive Officers of the Registrant'' in
Part I, Item 4(A) of this Report.

   Compliance with Section 16(a) of the Exchange Act: Section 16(a) of the
Exchange Act, and the regulations of the Commission thereunder require NOVA's
directors, officers and any persons who own more than 10% of NOVA's common
stock, as well as certain affiliates of such persons, to file reports with the

                        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, 1996. 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, present fairly in all
material respects the information set forth therein.

In our opinion, the accompanying consolidated balance sheet and the related 
consolidated statements of income, of changes in shareholders' equity and of 
cash flows 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

                                  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 income 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.

                                       1

                  NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
                                        

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 costs 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.

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.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS


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.

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.

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 statement

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 income 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 $10,743,645, expenses of $11,022,698 and net loss before provision 
of 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, the Company completed six separate operating
business combinations during the year ended October 31, 1998 and the year ended
July 31, 1997, with six unrelated entities. The Company issued an aggregate of
3,577,914 shares of NOVA common stock 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 PORTFOLIO PURCHASES AND JOINT VENTURES


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.
                                       8
<PAGE>
 
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 the PMT merger 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
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 merchants 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.

The Company's experience indicates a portion of the leases will terminate at
dates other than the end of the contractual period. Accordingly, the foregoing

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 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 waiver 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 components of the provision (benefit) for income taxes are as follows:

The Company has approximately $1.0 million of federal and state net operating
loss carryforwards and $.9 million of Alternative Minimum Tax ("AMT") credits
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 and AMT credits as utilization by the applicable
subsidiaries is not reasonably assured.

                                CAPITALIZATION

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 secondary 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 $142.5 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.

                              STOCK OPTION PLANS

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:

     ================================================================================
</TABLE>

The Black-Scholes option valuation model was developed for use in estimating the
fair value of traded options, which have no vesting restrictions and are fully
transferable.  In addition, option valuation models require the input 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 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 committe 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 stock in an
amount and per share price adjusted to reflect the exchange ratio of .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.

A summary of option activity follows (amounts in thousands, except per share

                             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 Stock. 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 1006.

                                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 $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

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.
