                                    PART I
 
ITEM 1. BUSINESS
 
  NOVA Corporation, a Georgia corporation (the "Company"), is an integrated
provider of transaction processing services, related software application
products and value-added services primarily to small- to medium-sized
merchants. The Company provides transaction processing support for all major
credit and charge cards, including VISA, MasterCard, American Express,
Discover, Diner's Club and JCB, and also provides access to debit card
processing and check verification services. The Company believes it is the
nation's largest transaction processor focused primarily on small- to medium-
sized merchants, and that it was the fifth largest bankcard processor in the
United States at December 31, 1997, after giving pro forma effect to the
recent transactions completed since January 1997 discussed below. On a pro
forma basis giving effect to the recent transactions discussed below, the
aggregate dollar volume of VISA and MasterCard credit card transactions
processed by the Company in 1997 would have been over $24.0 billion.
 
  The Company 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, the Company has developed several software
applications that can be delivered to its customers and updated via the
Company's proprietary telecommunications network (the "NOVA Network"). The
NOVA Network was developed in conjunction with WorldCom, Inc. ("WorldCom") and
is the principal conduit through which the Company provides its services. The
capabilities of the NOVA Network result in rapid response time and its
substantial bandwidth facilitates the delivery of sophisticated value-added
services. The Company's ability to effectively employ technology, together
with the capabilities of the NOVA Network, allow the Company to respond
quickly and effectively to the changing and diverse needs of its merchant
customers.
 
  The Company was incorporated in Georgia in December 1995 in connection with
an alliance between the Company and First Union Corporation ("First Union")
(the "First Union Alliance"). NOVA Information Systems, Inc., a wholly-owned
subsidiary and predecessor to the Company ("NOVA Information Systems"), was
incorporated in Georgia in February 1991. Unless the context otherwise
requires, references in this Annual Report on Form 10-K to "NOVA" and the
"Company" refer to NOVA Corporation and its subsidiaries.
 
  This Annual Report on Form 10-K contains "forward-looking statements" within
the meaning of Section 27A of the Securities Act of 1933, as amended (the
"Securities Act"), which represent the Company's expectations or beliefs,
including, but not limited to, statements concerning transaction volume and
the impact of acquisitions, joint ventures and alliances. When used in this
report, the words "may," "could," "should," "would," "believe," "anticipate,"
"estimate," "expect," "intend," "plan" and similar expressions are intended to
identify forward-looking statements. These statements by their nature involve
substantial risks and uncertainties, certain of which are beyond the Company's
control. The Company cautions that various factors, including the factors
described in the Company's filings with the Securities and Exchange Commission
(the "Commission"), as well as general economic conditions and industry trends
could cause actual results or outcomes to differ materially from those
expressed in any forward-looking statements of the Company. Any forward-
looking statement speaks only as of the date of this report, and the Company
undertakes no obligation to update any forward-looking statement or statements
to reflect events or circumstances after the date on which such statement is
made or to reflect the occurrence of an unanticipated event. New factors
emerge from time to time, and it is not possible for the Company to predict
all of such factors. Further, the Company 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.
 
RECENT TRANSACTIONS
 
  The Company consummated three significant transactions in 1997 and a fourth
in January 1998, which in the aggregate would have added approximately $10.9
billion of transaction processing volume to the Company's network if the
transactions had been consummated at the beginning of 1997. The transactions
collectively
 
                                       2
<PAGE>
 
represent increases of 91.4% over fiscal 1996 transaction processing volume of
$11.9 billion. The aggregate maximum consideration paid or to be paid by the
Company in connection with these four transactions is approximately $140.1
million. The Company also consummated 16 community bank transactions in 1997,
for an aggregate purchase price of approximately $10.0 million and which, in
the aggregate, represent approximately $774.0 million of transaction
processing volume.
 
  KeyBank Joint Venture. On January 21, 1998, the Company consummated a
transaction (the "KeyBank Joint Venture") with KeyBank National Association
("KeyBank") pursuant to which the Company and KeyBank formed Key Merchant
Services, LLC, a Delaware limited liability company ("Key Merchant Services")
jointly owned and operated by Key Payment Services, Inc., a wholly owned
subsidiary of KeyBank, and the Company. In connection with the KeyBank Joint
Venture, KeyBank, Key Payment Services and POS Sales and Services, Inc., a
wholly owned subsidiary of KeyBank, contributed substantially all of their
then existing bankcard payment processing contracts (representing
approximately $5.1 billion in annualized credit and debit card volume) to Key
Merchant Services. The Company purchased a 51% interest in Key Merchant
Services from KeyBank and POS Sales and Services.
 
  Key Merchant Services has an initial operating term expiring in January 2005
with automatic three-year extensions unless either Key Payment Services or the
Company, as the sole members of Key Merchant Services, gives notice of
termination at least 12 months prior to a scheduled expiration date. Although
certain authority is reserved exclusively in a Management Committee, a
Manager, who is a designated employee of the Company, has the power and
authority to make decisions and take actions on behalf of Key Merchant
Services in connection with its day-to-day operation and management in the
ordinary course of business. The Management Committee is comprised of five
persons, with two members selected by Key Payment Services and three members
selected by the Company. The Company also will provide to Key Merchant
Services transaction processing and other services for which the Company will
receive compensation. Key Merchant Services will market transaction processing
services with its own employees throughout the United States. Further, KeyBank
will market and promote, on an exclusive basis, transaction processing
services on behalf of Key Merchant Services through KeyBank's bank branch
locations. KeyBank and its affiliate banks also agreed to provide certain
other services, including clearing and settlement services, to Key Merchant
Services for which KeyBank will receive compensation.
 
  Upon termination or expiration of the KeyBank Joint Venture, either KeyBank
or the Company, depending on the circumstances of such termination or
expiration, may elect to purchase the other party's interest in Key Merchant
Services at "fair market value" determined pursuant to the terms of the
KeyBank Joint Venture.
 
  In connection with the formation of Key Merchant Services, the Company has
undertaken the conversion of merchant processing to the Company's operating
platform. In addition to the Company's normal conversion related expenses, the
Company expects to accrue a non-recurring charge of approximately $1.3
million, net of tax ($0.04 per share assuming dilution and prior to giving
effect to this offering), in the first quarter of 1998 principally to account
for early termination of a contract for merchant processing with a third party
processor.
 
  MBNA Portfolio. On December 30, 1997, the Company consummated a transaction
with MBNA America Bank, N.A. ("MBNA") pursuant to which the Company purchased
substantially all of MBNA's merchant portfolio. In connection with the MBNA
transaction, MBNA has agreed to cooperate with the Company in marketing the
Company's merchant transaction processing services and to refer exclusively to
the Company all merchants, trade associations, financial institutions,
independent sales organizations ("ISOs") and other organizations that request
or evidence an interest in merchant transaction processing services. The
Company, among other things, is required to pay to MBNA a fee for each
merchant that enters into a merchant transaction processing contract with the
Company as a result of any such referral. In conjunction with the MBNA
transaction, the Company agreed to pay to MBNA a percentage of the portfolio's
net revenues. The Company's marketing agreement with MBNA has an initial term
of ten years (i.e., through December 31, 2007) subject to automatic two year
extensions unless either party gives notice of termination at least 75 days
prior to an expiration date. The Company estimates that the MBNA portfolio
will add approximately $1.0 billion in annualized credit and debit card
transaction processing volume.
 
 
                                       3
<PAGE>
 
  Firstar Joint Venture. Effective on October 31, 1997, the Company
consummated a transaction (the "Firstar Joint Venture") with Firstar Bank
U.S.A., N.A. ("Firstar") and Firstar Milwaukee, each of which are subsidiaries
of Firstar Corporation, pursuant to which the Company and Firstar jointly own
and operate Elan Merchant Services, LLC ("Elan Merchant Services"), a newly
formed limited liability company. In connection with the Firstar Joint
Venture, Firstar, Firstar Milwaukee and the other banking affiliates of
Firstar contributed substantially all of their then existing bankcard payment
processing contracts (representing approximately $3.0 billion in annualized
credit and debit card volume) to Elan Merchant Services in return for a 49%
equity interest in Elan Merchant Services, and the Company purchased a 51%
interest in Elan Merchant Services.
 
  Elan Merchant Services has an initial term expiring on August 31, 2008, with
automatic one-year extensions unless either Firstar or the Company, as the
sole members of Elan Merchant Services, gives notice of termination at least
six months prior to a scheduled expiration date. Although certain powers are
reserved exclusively in a Management Committee, the Company, as Manager of
Elan Merchant Services, has the power and authority to make decisions and take
actions on behalf of Elan Merchant Services 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 the Company. Elan Merchant Services pays the Company an annual fee
for its managerial services. The Company also provides to Elan Merchant
Services transaction processing and other services for which the Company
receives compensation. Firstar will market and promote, on an exclusive basis,
transaction processing services on behalf of Elan Merchant Services directly
and through a network of over 850 correspondent financial institutions. Elan
Merchant Services, among other things, is required to pay to Firstar a fee for
each merchant that enters into a merchant transaction processing contract with
Elan Merchant Services as a result of any such referral, including a fixed
percentage of sales volume the referred merchant processes through the
Company. Firstar and its affiliate banks also agreed to provide certain other
services, including clearing and settlement services, to Elan Merchant
Services for which Firstar receives compensation.
 
  Upon termination or expiration of the Firstar Joint Venture, either Firstar
or the Company, depending on the circumstances of such termination or
expiration, may elect to purchase the other party's interest in Elan Merchant
Services at the "fair market value" determined through negotiations between
the parties at the time of termination. If Firstar and the Company are unable
to mutually agree upon the "fair market value," an independent appraiser shall
make such determination.
 
  Crestar Portfolio. On May 29, 1997, the Company consummated a transaction
with Crestar Bank pursuant to which the Company purchased substantially all of
Crestar Bank's merchant portfolio. Crestar Bank has agreed that for an initial
term expiring May 1, 2002 (subject to automatic two-year extensions unless
either party gives notice of termination at least 180 days prior to an
expiration date), Crestar Bank will cooperate with the Company in marketing
the Company's merchant transaction processing services and refer exclusively
to the Company all merchants, financial institutions, ISOs and other
organizations that request or evidence an interest in merchant transaction
processing services. The Company, among other things, is required to pay to
Crestar Bank a fee for each such referral, including a fixed percentage of
sales volume the referred merchant processes through the Company.
 
  The Company estimates that the Crestar portfolio will add approximately $1.8
billion in annualized credit and debit card transaction processing volume.
Crestar Bank's 500 branch locations will offer the Company's transaction
processing services, thereby expanding the Company's distribution network.
 
  The Company expects each of these transactions to provide significant
strategic and financial benefits, including: (i) enhanced distribution
channels to facilitate growth of the Company's processed transaction volume
and number of merchant locations served; (ii) further geographic
diversification of the Company's merchant portfolio into additional regions of
the United States; and (iii) economies of scale from substantial increases in
transaction processing volume once the merchant accounts and other services
are fully integrated into the Company's operating platform.

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 the efficiencies derived from economies of scale,
are causing 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 five years ended December 31, 1996, charge volume of VISA and MasterCard
credit cards grew at a compounded annual growth rate of approximately 18.7%.
The growth in charge volume and the increase in the acceptance of credit cards
are expected to continue as consumers expand their use of such cards as an
alternative to cash and checks. VISA and MasterCard charge volume is projected
to exceed $1.0 trillion by the year 2000 (The Nilson Report--September 1996).
 
 
  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. According to industry sources,
approximately 87% of the dollar volume of credit card transactions was
processed electronically or by voice automation in 1995, up from approximately
77% in 1990. 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 merchants.
 
  At present, many large transaction processors continue to provide customer
service and applications via legacy systems that are difficult and costly to
alter or otherwise customize. Accordingly, transaction processors that
continue to utilize these systems for customer service and applications 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 more expensive and less flexible
legacy systems, advances in less costly, scalable and networked computer
systems, including distributed client/server architecture and relational
database management systems, afford transaction processors greatly improved
flexibility and responsiveness in providing customer service and applications.
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.
 
  Advances in personal computer ("PC") and POS terminal technology have
increasingly allowed access to a greater array and level of sophisticated
services at the POS and contributed to the demand for such services. In
addition, more sophisticated uses of integrated cash registers and networked
systems at the merchant site create further demand for comparably advanced and
sophisticated products and services accessible at the POS. These trends have
created the 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 primarily focus 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, small- to medium-sized
merchants historically have not been offered the same level of services as
large merchants and have incurred relatively higher per-transaction costs. The
growth in card
 
                                       5
<PAGE>
 
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.
 
  Transaction processing services are marketed and sold to the small- to
medium-sized merchant market segment primarily by community and regional banks
and ISOs that 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, the small- to medium-sized merchant market segment historically
has been characterized by basic transaction processing without the
availability of the more sophisticated processing, information-based services
or customer service 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 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 evolving demands, and are increasingly exiting the transaction
processing business or otherwise seeking alliance partners to provide
transaction processing for their customers. Despite this ongoing
consolidation, the industry remains fragmented with respect to the number of
entities providing merchant services. Industry sources indicate that in 1997,
although the ten largest bankcard processors accounted for approximately 85%
of the total charge volume processed and the largest accounted for
approximately 38% of the total volume, there were 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 THE COMPANY
 
  Authorization Services. The Company provides electronic transaction
authorization services for all major credit and charge cards. Authorization
generally involves approving a cardholder's purchase at the POS after
verifying that the card is not 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 dollar amount of the purchase.
After capturing the data, the POS terminal transmits the authorization request
via the NOVA Network to the Company's switching center, where the data is
routed to the appropriate credit card association for authorization. The
transaction is approved or declined by the credit card association, and the
response is transmitted back to the Company'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 the
Company. This redundancy maximizes accurate transaction reconciliation with
each merchant and protects 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 the Company has programmed into the
merchant's POS terminal, and transmits this information to the Company where
it is organized into two files. One file is transmitted to either Vital
Processing Services L.L.C. (formerly Total System Services, Inc.) ("Vital
Processing Services") or Mellon Bank, N.A. ("Mellon Bank") for merchant
accounting as described below. The other file is maintained by the Company in
its database to allow the Company to run its proprietary fraud detection
software program against each of the day's transactions processed via the NOVA
Network. This information also allows the Company to provide merchants with
information services such as specialized management reports and to assist in
its other customer service operations. Merchants can access this archived
information through customer service representatives or through applications
such as NOVA ACS and NOVA Perks which allow the merchant direct access to the
Company's database through a PC.
 
 
                                       6
<PAGE>
 
  Settlement, Accounting and Clearing Services. Merchant accounting services
are performed on the Company's behalf by Vital Processing Services and Mellon
Bank, with each of the Company's merchant customers assigned to one of these
processors. No less often than once each day, the Company forwards to Vital
Processing Services and Mellon Bank, respectively, transaction data regarding
the Company's merchant customers. Vital Processing Services and Mellon Bank
reorganize and accumulate this data on a merchant-by-merchant and card issuer-
by-card issuer basis and forward this data to the credit card associations for
ultimate payment. On a monthly basis, Vital Processing Services and Mellon
Bank send statements to the Company's merchant customers for whom they provide
settlement and accounting services, detailing the previous month's transaction
activity.
 
  Through each of Regions Bank, Bank of the West, Mellon Bank, Firstar,
KeyBank and First Union National Bank ("FUNB"), a subsidiary of First Union,
which serve as member clearing banks for the Company, the Company is
registered with the VISA and MasterCard credit card associations as a
certified processor and member service provider. The Company'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, the Company 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, the Company assists the merchant in investigating and
resolving the dispute. These billing disputes include, among others: (i)
nonreceipt of merchandise or services; (ii) unauthorized use of a credit card;
and (iii) general disputes between a customer and a merchant as to the quality
of the goods purchased or the services rendered by that merchant. The Company
provides a sophisticated chargeback control system for its merchants that
includes actively prescreening disputes and the use of proprietary software
programs to automate chargeback controls. These chargeback control systems are
designed to reduce the time and expense that the Company and merchants spend
on cardholder requests for chargebacks. In the event a billing dispute between
a cardholder and a merchant is not resolved in favor of the merchant, the
transaction is "charged back" to the merchant and that amount is credited or
otherwise refunded to the cardholder. If the Company or its clearing banks are
unable to collect such amounts from the merchant's account, and if the
merchant refuses or is unable due to bankruptcy or other reasons to reimburse
the Company for the chargeback, the Company bears the loss for the amount of
the refund paid to the cardholder.
 
  Customer Service and Support. The Company provides its merchant customers
with a variety of customer services and support. These services include
leasing, renting or selling POS terminals, downloading software application
products and services to POS terminals, maintaining POS terminals, and
customizing software for merchant applications. In addition, the Company
maintains a 24-hours-a-day, seven-days-a-week helpline staffed by full-time
customer service representatives.
 
TECHNOLOGY
 
  One of the Company's principal strategies is to maximize the benefits of
available technologies to deliver transaction processing and related software
application products and services on a cost-effective basis. Accordingly, the
Company regularly uses and adapts 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 the Company's service capabilities.
 
  The Company exercises significant control over the development and
enhancement of the combination of hardware, software and network services that
comprise the Company's transaction processing and information delivery system.
This provides the Company with greater control over the functionality,
quality, reliability, cost and efficiency of its transaction processing
services and related software application products and services.

  The NOVA Network. The NOVA Network, developed in conjunction with WorldCom,
is the Company's proprietary telecommunications network and the principal
conduit through which the Company provides its services. The design of the
NOVA Network provides efficient switching capabilities, resulting in rapid
response time for transaction authorizations. Fiber optic communications are
employed throughout the NOVA Network, providing the substantial bandwidth
capable of supporting sophisticated value-added services. In working with
WorldCom, the Company was able to design a network specifically tailored to
the services the Company desired to provide, the equipment the Company
intended to use in providing 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. Pursuant to
its agreement with the Company, WorldCom provides long-distance and local
telecommunication access, as well as technical support, to the Company in
connection with the NOVA Network. This agreement expires February 28, 1999,
subject to earlier termination by the Company if WorldCom fails to meet
certain agreed-upon performance objectives.
 
  The NOVA Network is the result of combining WorldCom's Common Channel
Signaling Specification Number Seven, commonly referred to as an "SS7"
switching system, with the use of advanced Integrated Services Digital Network
("ISDN") and Non-Facilities Associated Signaling ("NFAS") features. SS7 is a
high-speed call-switching technology utilized in telecommunications networks
and originally intended only for carrier-to-carrier use, such as a regional
phone company switching long-distance calls to WorldCom for transmission, as
opposed to use by end-users such as the Company and its merchants. With the
use of ISDN technology, however, end-users such as the Company can utilize an
SS7 switching system without sacrificing any of the enhanced performance
attributes derived from SS7 technology. Although significant hardware and
software obstacles currently are inherent to end-user utilization of an SS7
switching system, the Company developed a proprietary ISDN interface enabling
it effectively to employ SS7 technology as part of the NOVA Network. Further,
the NFAS features of the NOVA Network allow for a greater portability of the
NOVA Network to long-distance and local telecommunications access providers
other than WorldCom, which would reduce the Company's historical dependence on
WorldCom. The Company has developed and tested a network interface with AT&T
and management believes that, if necessary or convenient, the Company could
utilize the telecommunications access of AT&T 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 the Company'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 WorldCom system,
enhances the Company's ability to provide a high level of reliability in its
network service. Through an agreement with Electronic Data Systems
Corporation, the Company 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.
 
  Software Development for POS Terminals and PCs. The Company is continuously
developing new software applications for POS terminals and PCs in an effort to
improve existing and create additional product and service offerings. This
software development capability is critical to the Company's ability to
respond flexibly to changing customer needs and improving technologies. Most
of the POS terminals utilized by the Company's merchant customers have been
programmed by the Company with specific applications. By programming POS
terminals, the Company 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. Distribution of software application products designed for use
through POS terminals generally is accomplished by downloading such
applications over the NOVA Network, enabling a merchant to utilize the
Company's products and services quickly and inexpensively.
 
 
                                       8

  As the use of PCs by merchants grows, and as merchants continue to move
toward fully-integrated cash registers and payment systems, the Company
continues its efforts to extend its POS terminal software application product
and service offerings to PCs. For instance, NOVA ACS, NOVA Perks, PC Transact
It, and NOVA Shadow Pay are PC-based applications, and the Company intends to
expand the number of its products and services available for PC use or that
otherwise allow the POS terminal to interface with a PC. 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, the Company expects
such use to increase. Further, the terms of the First Union Alliance provide
that, when feasible, the Company will assist First Union in developing new
products or services relating to transaction processing or in otherwise
supporting new business ventures. The Company and First Union are actively
pursuing initiatives relating to transaction processing via the Internet and
procurement and purchasing cards, and management believes that these and other
efforts may result in the development of additional software application
products and value-added services.
 
  The Company actively encourages third party software developers to write
applications to the Company's specifications and network protocols. These
applications, once certified by the Company, allow integration of the
Company'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 the Company as
they frequently market their business management software in connection with
the Company's services. For example, Squirrel Restaurant Products
("Squirrel"), one of the leading VARs, provides software applications to
accommodate the specialized business management needs of the restaurant
industry. Squirrel, in cooperation with the Company, has modified its software
to allow full integration of the Company's transaction processing services. In
this way, VARs such as Squirrel indirectly perform a marketing function for
the Company since their software is often offered on a fully- integrated basis
with the Company's transaction processing services, creating additional
opportunities for the Company to reach small- to medium-sized merchants. The
Company has certified in excess of 30 third party software developers,
including IC Verify, Aluim Payment Groups, Southern DataCom, Inc., Datacap,
Inc. and Smokey Mountain Systems.
 
  Use of Networked Systems for Customer Service. The information access and
retrieval capabilities of networked systems, where real-time information is
available to any of the Company's customer service representatives, allow the
Company to provide a level of customer service and support to small- to
medium-sized merchants previously available only to much larger merchants. For
example, any of the Company'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. The Company also
recently implemented an on-line, informational database that provides the
Company's customer services representatives user-friendly access to an array
of additional information relative to the Company's services, products and
systems, which often allows the Company to more quickly and effectively
resolve customer service inquiries. In addition to their customer service
capabilities, the Company's networked systems are highly automated and require
minimal staffing, which allows the Company to contain costs and achieve
greater operating efficiencies.
 
  Year 2000 Updates. The Company must address Year 2000 compliance for POS
merchant activity, internal operating systems and suppliers and vendors. In
June 1997, the Company was certified by VISA U.S.A. and Mastercard
International as capable of processing transactions for cards issued with
expiration dates of 2000 and beyond. All of the Company's customers have been
upgraded with compliant transaction processing software, and the Company's
network and switch can accommodate the Year 2000.
 
  The Company has developed a plan to ensure all internal systems are
compliant with the Year 2000. These efforts are under way and are scheduled to
be completed by year end 1998. The Company's significant outside vendors and
suppliers also are scheduled to be Year 2000 compliant by year end 1998.
However, while the Company believes its planning efforts are adequate to
address its Year 2000 concerns, there can be no guarantee that the systems of
other companies on which the Company's systems and operations rely will be
properly converted on a timely basis and will not have a material effect on
the Company. It is assumed that should any vendor not be compliant by January
1, 1999, the Company will have sufficient time to engage an alternative
 
                                       9
<PAGE>
 
vendor which is compliant. The cost of Year 2000 initiatives has not been and
is not expected to be material to the Company's results of operations or
financial position.
 
SOFTWARE APPLICATION PRODUCTS AND VALUE-ADDED SERVICES
 
  In addition to card transaction processing, the Company offers related
software application products and value- added services to its merchant
customers. These products and services are designed to run on existing POS
terminals and DOS- and Windows-based PCs. Offering a broad range of products
and services historically unavailable to small- to medium-sized merchants is
an integral part of the Company's strategy of focusing on these merchants and
differentiating itself among the banks and ISOs serving this market segment.
Management believes that the quality and reliability of its products and
services enhance the Company's ability to attract and retain merchant
customers.
 
  The Company currently offers a variety of software application products and
value-added services, including the following core products and services that
are basic to the Company's network:
 
  Encompass. Encompass is the latest generation of the Company's user
interface. The Company presently provides Encompass to all new merchant
customers, and generally charges a one-time fee to upgrade existing merchants
to Encompass. In addition to the Company's core transaction processing
services, Encompass enables merchants to access the Company's software
application products and value-added services, including those described
below. 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, Encompass allows the merchant to add features and
capability as its business needs evolve. Generally available since July 1994,
Encompass is a POS terminal application currently used by over 60,000
merchants.
 
  NOVA Shadow Pay. NOVA Shadow Pay, introduced by the Company in February
1996, 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. Typically, merchants accepting cards
for payment key-in or input transaction data at their cash register and then
key-in certain redundant transaction data to their POS terminal for
authorization and processing. This redundant keying of data increases both the
probability of human error as well as the amount of time it takes a merchant
to process a transaction. 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 the redundant keying of transaction data
associated therewith. 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. The
Company charges a one-time license fee for access to NOVA Shadow Pay. NOVA
Shadow Pay currently is used by approximately 1,000 merchants.
 
  Mass Transact and PC Transact It. Mass Transact is a mainframe-to-mainframe
transaction processing application that the Company developed specifically for
businesses utilizing mainframe technology and processing large numbers of
credit card transactions on a batch basis. A merchant using 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 the Company 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 Mass Transact. Available since September 1994,
Mass Transact currently is used by approximately 300 of the Company's
merchants. PC Transact It is a similar application that allows PCs, rather
than mainframes, to process transactions on a batch basis. Available since
October 1994, PC Transact It currently is used by approximately 3,500 of the
Company's merchants. Merchants who subscribe to Mass
 
                                      10
<PAGE>
 
Transact or PC Transact It pay a one-time license fee and a percentage of the
dollar 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 PC-based lodging solution for small
hotels and motels and tracks check-in and check-out data by portfolio.
NOVALodge, the Company's most recent product release, 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. Over 4,000 merchants currently use
one of these applications.
 
  Gratuit. Gratuit is a transaction processing application designed
specifically for use by restaurants. Gratuit tracks server data and includes
"tip" capability and enhanced reporting capabilities. Similar to Encompass,
Gratuit software integrates a time clock into the software as well as a
frequent diner program. Gratuit currently is used by over 6,000 NOVA
merchants.
 
  In addition to the Company's core products and services, the Company offers
the following value-added software applications and services:
 
  NOVA ACS. NOVA ACS (Automated Customer Service) is a PC-based system that
allows the Company's bank alliance and ISO partners access to the Company's
databases in order to track and compile the transaction processing activity of
their respective merchant customers. NOVA ACS also is utilized by the
Company's merchant customers to access the Company'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 2.5, 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. Available since 1991, NOVA ACS currently is used by approximately 300 of
the Company's bank alliance and ISO partners.
 
  SCAN Check Verification Services. Through an agreement with Deluxe Payment
Protection Systems, Inc. ("DPPS"), doing business as SCAN, the Company offers
check verification services to its customers. Specifically, the Company can
provide its customers with direct access via the NOVA Network to the SCAN
database managed by DPPS. The SCAN database is composed of information
relating to checks returned to subscribers of the SCAN database for
insufficient funds. This access allows merchants to compare the information
included in the database against any check presented to the merchant for
payment. This service is accessible to the merchant through the merchant's POS
terminal and was introduced in May 1995, with significant telemarketing of
SCAN to existing Company merchants commencing in January 1996. Merchants pay
per-transaction fees for access to such service. The service currently is used
by approximately 1,000 merchants.
 
  In March 1997, the Company entered into an additional agreement with DPPS
pursuant to which DPPS agreed to refer to the Company prospective merchants
for credit, charge and debit card processing.
 
  Cellular Digital Packet Data. The use of Cellular Digital Packet Data
("CDPD"), marketed under the name "Traverse," allows the Company to process
transactions utilizing cellular airwaves, as opposed to traditional phone
lines, enabling wireless transaction authorization and processing. The Company
currently has agreements with AT&T Wireless Services, GTE and Bell Atlantic
NYNEX Mobile to provide cellular transmission services. CDPD 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, CDPD will allow merchants that have relied on
paper-based processing, where the ability to check if a card is stolen or
credit limits exceeded is
 
                                      11
<PAGE>
 
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. Through an agreement with Harbinger Corporation, the Company
offers Internet services to merchant customers. NOVA WEBWAY is software
designed to allow small- to medium-sized 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. The Company has several merchants testing this
product and began a marketing campaign in March 1998.
 
  Internet Processing. The Company is actively pursuing development
initiatives relating to transaction processing services on the Internet and
other forms of electronic commerce. The Company is exploring with First Union
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, the Company has entered into an agreement with
CyberCash Inc. pursuant to which CyberCash will provide to the Company
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. The Company, however, is
active in the development process and management believes that the Internet
may, ultimately, become another distribution channel for the Company'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 the Company for transaction
processing services can still utilize NOVA Perks. NOVA Perks has not yet
achieved significant market usage although it is an attractive product to
prospective customers.
 
CUSTOMER BASE
 
  The Company'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 the Company insofar as those banks accept credit
card cash advance transactions. While the Company's merchants vary
significantly in size, a typical merchant customer generates approximately
$140,000 in annual charge volume. Although the Company focuses on small- to
medium-sized merchants, the Company 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, 1997 and 1996, no merchant customer accounted for more than
2.5% of the Company's revenues. At December 31, 1997, the Company provided
transaction processing services to approximately 152,000 merchant locations
nationwide.
 
  The Company enters into direct contractual relationships with its merchants,
which reduce the financial risks to the Company in the event any of the
Company's bank alliance partners no longer desire to utilize the Company's
services. In contrast to the Company'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.

MARKETING
 
  To reach its target market segment in a cost-effective manner and to further
its market penetration, the Company markets its services through three
principal channels: (i) bank alliances, including joint ventures, through
which the Company offers its services to merchants in cooperation with
community and regional banks, allowing the Company to capitalize on the
presence of those banks in particular geographic markets; (ii) partnering with
ISOs that market and sell the Company's services to merchants, typically in
areas where the Company does not have bank alliances; and (iii) direct sales
on behalf of and as a supplement to the bank alliance and ISO partnering
channels. In addition, the Company engages in marketing efforts that include
marketing agreements with various trade and other associations and marketing
through VARs that integrate the Company's transaction processing services with
specialized business management software. The KeyBank Joint Venture, the
Firstar Joint Venture, the Crestar transaction, the MBNA transaction and the
First Union Alliance are the Company's most significant examples of marketing
through bank alliances, and enhanced significantly the Company'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. The Company's principal marketing efforts are directed at
forming bank alliances. During 1997 and January 1998, the Company entered into
bank alliances in connection with the KeyBank Joint Venture, the Firstar Joint
Venture, the Crestar transaction and the MBNA transaction. Through its
relationships with its bank alliance partners, the Company offers its services
to merchants in cooperation with community and regional banks, allowing the
Company to capitalize on the presence of those banks in particular geographic
markets. The Company's bank alliances consist of four types of relationships:
(i) relationships created as a result of the Company's purchase of a bank's
merchant portfolio, pursuant to which the Company provides transaction
processing services on a co-branded basis with such bank ("Acquisition
Alliances"); (ii) relationships created through a joint venture (generally in
the form of a limited liability company) owned jointly by the Company and a
bank, pursuant to which the Company provides transaction processing services
to the joint venture and the bank provides marketing and referral services to
the joint venture ("Joint Venture Alliances"); (iii) agent bank relationships
where the bank purchases the Company's services and markets and resells those
services directly to merchants ("Agent Bank Alliances"); and (iv) bank
referral relationships where the bank refers to the Company merchants who
desire or otherwise inquire about transaction processing services ("Bank
Referral Alliances").
 
  Acquisition Alliances and Joint Venture Alliances are an integral part of
the Company's overall acquisition strategy pursuant to which the Company
offers banks the opportunity to transfer management and operational
responsibility for their merchant portfolios to the Company (either directly
or through the joint venture), while continuing to offer transaction
processing services on a co-branded basis in cooperation with the Company.
Because an Acquisition Alliance or a Joint Venture Alliance may involve the
Company (or the joint venture) maintaining transaction processing salespersons
on-site at the bank branch to service existing merchant customers and to
market and sell the Company's processing services to new merchant customers,
the Company can often effect a nondisruptive transition of services from the
merchants' perspective. To ease further this transition process and to assist
its Acquisition Alliance and Joint Venture Alliance partners, the Company has
created an intensive training program whereby the Company's personnel train
and educate its Acquisition Alliance and Joint Venture Alliance partners in
all aspects of the Company's transaction processing services, software
application products and value-added services. Additionally, the Company
utilizes its internal sales force to market transaction processing services on
behalf of the Acquisition Alliances and Joint Venture Alliances. 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.
 
  The Company compensates its bank alliance partners through varying means.
Acquisition Alliance partners typically are compensated by the Company
remitting to them a residual for each transaction processed by the Company for
merchants attributable to the alliance. The Company compensates its Bank
Referral Alliance partners typically by paying them a one-time referral fee.
Agent Bank Alliance partners are not directly compensated by the Company;
rather, they derive revenue by reselling the Company's services to merchants
at a
 
                                      13
<PAGE>
 
price determined by the Agent Bank. The Company is assisted in 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
the Company. The Company's agreement with Kessler is scheduled to expire June
30, 2001, subject to renewal for two additional years unless either the
Company or Kessler gives notice of termination prior to the expiration of the
initial term.
 
  The Company also employs a direct sales force that markets the services of
the Company on behalf of the Company's alliance, ISO and joint venture
partners.
 
  ISO Partnering. With the acquisition of the merchant portfolio of the Bank
of Boulder in December 1994, which included 24 marketing agreements with ISOs,
the Company made its first significant entry into the ISO marketing channel.
ISOs are entities that market the Company'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 the
Company's products and services on a non-exclusive basis. An ISO that desires
to refer a merchant customer to the Company will procure the merchant's
application and submit it to the Company on the merchant's behalf. Thereafter,
if the application is approved, the ISO will sell or lease POS terminals and
related hardware and software to such merchant. The Company compensates ISOs
by paying them a residual for each transaction processed by the Company for
merchants referred to the Company by the ISO. The ISO's determination of
whether to refer a particular merchant to the Company depends on a variety of
factors, including the terms of the residual offered by the Company and the
industry in which the merchant conducts its business. As of March 19, 1998,
the Company had 40 marketing agreements with ISOs.
 
  Association Marketing. Through its association marketing program, the
Company 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
the Company, creating additional opportunities for the Company to reach small-
to medium-sized merchants. The Company currently has agreements with 160
associations. The Company expects that the MBNA transaction will expand the
Company's association marketing opportunities.
 
  Other Marketing Efforts. In addition to bank alliances, ISO partnering and
direct sales and telemarketing, the Company engages in other marketing efforts
that management believes complement and diversify further the Company's
overall marketing strategy:
 
  Marketing Through VARs. The Company'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 VARs. VARs
perform a marketing function for the Company since their software often is
offered on a fully-integrated basis with the Company's transaction processing
services, creating additional opportunities for the Company to reach small- to
medium-sized merchants.
 
  Procurement and Purchasing Cards. Corporate procurement and purchasing cards
are growing in popularity and flexibility of use, and the Company is exploring
opportunities intended to take advantage of this emergence. Procurement and
purchasing cards, although very similar in most respects to bank and charge
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 by such policy holders of medical supplies,
prescriptions and services from certain health care providers, all of whom
have agreed, in advance, to accept the insurance company's purchasing cards.
 
  The Company 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 the
Company has not experienced any significant conflict while pursuing its
overall sales strategy.
 
 
                                      14

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, the Company has pursued an active acquisition strategy,
including the formation of joint ventures and bank alliances, and has
consummated 90 transactions since its inception in 1991, consisting of 84
merchant portfolio purchases, three operating business acquisitions, two joint
ventures and the First Union Alliance. In 1996, the Company consummated 13
transactions, which added approximately $317.2 million in annualized
processing volume. Since January 1997 (through January 1998), the Company has
consummated 20 transactions, anticipated to add $11.7 billion in annualized
processing volume.
 
  The Company intends to continue to pursue purchases of merchant portfolios
and the formation of joint ventures and alliances with other financial
institutions as a principal component of its growth strategy in order to
facilitate growth, expand the Company'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. The
Company attempts to structure its acquisitions, joint ventures and alliances
both to increase its merchant base and to expand its distribution and
marketing capabilities. The Company accomplishes this objective principally by
entering into an exclusive marketing agreement with a bank that sells its
merchant portfolio to, or enters into a joint venture or alliance with, the
Company. The exclusive marketing agreement typically provides that the bank
will refer to the Company, on an exclusive basis and for a period of up to ten
years, any merchants that request or otherwise inquire about transaction
processing services. This agreement generally also provides that the bank will
not compete with the Company in the provision of transaction processing
services during the term of the agreement and, in some cases, for a period of
up to two years after expiration of the agreement. In addition, the Company or
the joint venture may continue to maintain on-site transaction processing
salespersons to service existing merchant customers and to market and sell the
Company's processing services to new merchant customers, often allowing the
Company to effect a nondisruptive transition of services from the merchants'
perspective. These purchases, joint ventures and alliances offer banks the
opportunity to transfer management and operational responsibility for their
merchant portfolios to the Company or the joint venture, while continuing to
offer transaction processing services on a co-branded basis in cooperation
with the Company. Banks are therefore able to view the purchase of their
merchant portfolio or the joint venture as a way to maintain a full-service
relationship with their merchant depositors.
 
  The Company continues to evaluate potential purchases of merchant
portfolios, joint ventures and alliances and to negotiate with several third
parties that may be seeking purchasers of their merchant portfolios, although
except as described in this Annual Report on Form 10-K, the Company 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 the Company, as the Company and each of First Union and Crestar Bank have
agreed that the Company generally may, at its option and subject to agreement
on price and other terms, purchase from First Union or Crestar Bank any
merchant portfolios purchased by First Union or Crestar Bank through whole-
bank or other acquisitions. See "--First Union Shareholders Agreement." In
November 1997, First Union announced that it had entered into an agreement to
acquire CoreStates Financial Corp ("CoreStates"), which has an estimated $3.0
billion merchant transaction processing portfolio. In the event this
acquisition is consummated, the Company will consider entering into
negotiations with First Union to acquire the CoreStates transaction processing
portfolio. There can be no assurance that First Union will complete its
acquisition of CoreStates or, if completed, that the Company could purchase
the CoreStates transaction processing portfolio on terms acceptable to the
Company, if at all. There can be no assurances as to the timing of such
transactions. Further, there can be no assurance that the First
 
                                      15

Union Alliance or the Crestar marketing relationship will provide any other
acquisition opportunities or that any such acquisition opportunities can be
completed on terms favorable to the Company, if at all.
 
RISK MANAGEMENT
 
  The Company views its risk management and fraud avoidance practices as
integral to its operations and overall success because of the Company's
potential liability for merchant fraud, chargebacks and other losses. Risk
management and fraud avoidance occur initially at the application stage, when
merchant applications are reviewed by the Company against certain criteria to
determine acceptance or denial. The criteria used by the Company to determine
whether to accept or deny applications, and the rate structure charged to a
particular merchant, include the credit history of the applicant, the industry
in which the applicant conducts its business and various other relevant
factors. In certain instances, guarantees may be required before an
application is approved.
 
  The Company's principal advantage in its risk management and fraud avoidance
capabilities is the ability to run its proprietary 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 the Company's overall program to control fraud and
manage risk and is an example of the Company's strategy of leveraging
available technologies, and the NOVA Network, to competitive advantage.
Specifically, the NOVA Network allows the Company to send a file comprised of
the day's transaction activity to its operations center in Knoxville,
Tennessee at or prior to the time it sends that information to Vital
Processing Services or Mellon Bank for merchant accounting. In Knoxville, the
Company runs its proprietary rule-based fraud detection software program
against each of the day's transactions processed on the NOVA Network,
resulting in a computer-generated identification of potentially fraudulent
activity. Once identified, the Company analyzes and reviews the suspect
transactions to resolve potential problems. This can be accomplished before
funds are transferred to the merchant in payment for such transactions. If the
Company needs more time to review a transaction or series of transactions,
however, the Company 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. The NOVA Network also
allows the Company to review certain types of transactions on a real time
basis, as they are processed. Consequently, the Company 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 the Company. Despite the
Company's risk management and fraud avoidance capabilities, the Company is
unable to identify all fraudulent transactions resulting in financial exposure
to the Company. Further, until the Company converts each newly acquired
merchant account to the Company's merchant accounting processors, the Company
is unable to apply fully its risk management and fraud avoidance practices to
such merchant accounts.
 
  In connection with portfolio purchases, the Company 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 the Company to the portfolio and identifying any high-
risk merchants contained in the portfolio. Upon completion of this review, the
Company determines whether the portfolio meets the Company's standards and
guidelines and is otherwise a suitable acquisition target. If the Company
decides to proceed with the proposed purchase, the Company will focus on the
high-risk merchants identified by its review and attempt to manage the risk
associated with such merchants. Typically, the Company 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 the Company for any liability associated with
such merchants. The experience accumulated by the Company during the course of
its purchases is constantly drawn upon to refine the Company's due diligence
procedures and practices, and management expects to continue to improve its
due diligence efforts. Nevertheless, there can be no assurance that the
Company's due diligence process will consistently identify all high-risk
merchants or that the Company will otherwise assess properly the risk
attributes of any purchased portfolio.

MERCHANT ACCOUNTING AND CLEARING BANK RELATIONSHIPS
 
  The Company relies upon third parties to provide merchant accounting and
clearing bank services to the Company and its merchant customers. In each of
these instances, the Company 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 functions are performed on the
Company's behalf by each of Vital Processing Services and Mellon Bank under
agreements expiring April 30, 1999 and June 30, 1999, respectively. The
Company currently is negotiating the terms of a new agreement with Vital
Processing Services.
 
  Clearing Bank Arrangements. The Company'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, the Company collects applicable merchant
discount and other fees from each merchant for transactions effected and
services provided during the preceding month. The Company, 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,
Mellon Bank, Firstar, KeyBank and FUNB, which serve as member clearing banks
for the Company, the Company is registered with VISA and MasterCard as a
certified processor and member service provider. While the Company's
registration as a certified processor and member service provider is necessary
in order for the Company 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.
 
  Regions Bank and Mellon Bank clear most of the Company's transactions while
Bank of the West clears only those transactions originating from merchants
acquired by the Company as part of the October 1993 purchase of the merchant
portfolio of Bank of the West. Pursuant to the First Union Alliance, FUNB, a
subsidiary of First Union, acts as the exclusive clearing and settlement bank,
subject to certain exceptions and conditions, for merchant customers of First
Union. While the Company's Depositary and Settlement Agreement with First
Union does contain certain conditions relative to the Company's ability to
transfer clearing and settlement functions for the merchant customers of First
Union away from First Union, the Company's agreements with its principal
member clearing banks generally provide that the merchant relationship is
controlled by the Company. Accordingly, the Company 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 the Company would be able to find a financial institution to
sponsor it on terms acceptable to the Company.
 
  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 the Company, which provide transaction processing services.
The new MSP rules implement a Processor Certification Program requiring the
Company and other TPPs to register as a TPP with MasterCard. The Company has
filed its registration as a "Type I" TPP. Type I TPPs must satisfy certain
criteria including requirements as to the number of merchant accounts
serviced, processing volume and concentration of risk. 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 Company believes that it meets
or exceeds all of the criteria to qualify as a Type I TPP. The failure by the
Company to qualify as a Type I TPP, or to maintain its status as a Type I TPP,
could have a material adverse effect on the business or operations of the
Company.

CUSTOMER SERVICE AND SUPPORT
 
  The Company is dedicated to providing reliable and effective customer
service and support to its merchant customers. The information access and
retrieval capabilities of networked systems, where real-time information is
available to any of the Company's customer service representatives, allow the
Company 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 the Company'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. The Company also has
implemented an on-line, informational database that provides the Company's
customer service representatives user-friendly access to an array of
additional information relative to the Company's services, products and
systems, which often allows the Company to more quickly and effectively
resolve customer service inquiries.
 
  The Company maintains a 24-hours-a-day, seven-days-a-week helpline at its
operations center in Knoxville, Tennessee. The Company 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.
The Company has developed comprehensive programs and procedures for training
its approximately 90 full-time customer service representatives to assist the
Company'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.
 
PROPRIETARY RIGHTS
 
  The Company 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 chargebacks. The Company
regards its proprietary software as protected by trade secret and copyright
laws of general applicability. The Company 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 the
Company's software or to otherwise obtain or use other information the Company
regards as proprietary. While the Company'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 the Company's success than other
factors such as the knowledge, ability and experience of the Company'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 the Company's software application
products infringe or may infringe the proprietary rights of such entities.
These third parties may seek damages from the Company as a result of such
alleged infringement, demand that the Company license certain proprietary
rights from them or otherwise demand that the Company 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 the
Company's financial condition and results of operations.
 
  The Company 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, the
Company 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 the Company will be able to do so on favorable terms or at all.
 
  The Company's trademarks include "NOVA," "NOVA Information Systems," "NOVA
ACS," "NOVA Remote ACS," "NOVA Time," "NOVA Clock," "NOVA Perks," "PC Transact
It" and "NOVA Shadow
 
                                      18
<PAGE>
 
Pay". To date, however, the Company only has sought to have "NOVA" and "NOVA
Perks" registered on the federal level. The Company's application to register
"NOVA" was refused and allowed to lapse without contesting the refusal.
 
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
the Company is highly competitive. The level of competitiveness has increased
significantly since the Company's inception and this trend is expected to
continue. The Company 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. The Company'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 the Company's competitors and potential competitors have greater financial,
technological, marketing and personnel resources than the Company, and there
can be no assurance that the Company 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 the Company's margins and may have a material adverse effect on the
Company's financial condition and results of operations.
 
  According to industry sources, the ten largest bankcard processors accounted
for approximately 85% of the total charge volume processed in 1997. The
largest bankcard processor accounted for approximately 38% of the total charge
volume processed in 1997, and the Company would have processed approximately
4.2% of the total charge volume for the same period after giving pro forma
effect to the transactions discussed in "--Recent Transactions."
 
  The Company believes that it has reached a sufficient size whereby economies
of scale allow it to offer competitive pricing. However, certain of the
Company's competitors may have lower costs which could potentially give them
an advantage. As a result of its experience in payment processing, the Company
has been able to develop operating efficiencies that the Company believes
allow it to competitively bid for new business. In addition, the Company 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. The Company 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.
 
  The Company faces increasing competition from other transaction processors
for available acquisition opportunities. In addition, community and regional
banks, which serve as a marketing channel for the Company's services and whose
transaction processing businesses have been the Company'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 the Company
or banks that have a relationship or alliance with one or more competitors of
the Company, thus potentially depriving the Company of distribution channels
and/or acquisition opportunities. The First Union Alliance and the Crestar
Alliance, however, may create additional acquisition opportunities for the
Company, as the Company and each of First Union and Crestar Bank have agreed
that the Company generally may, at its option and subject to agreement on
price and other terms, purchase from First Union or Crestar Bank any merchant
portfolios acquired by First Union or Crestar Bank through whole-bank or other
acquisitions. In November 1997, First Union announced that it had entered into
an agreement to acquire CoreStates, which has an estimated $3.0 billion
merchant transaction processing portfolio. In the event this acquisition is
consummated, the Company will consider entering into negotiations with First
Union to purchase the CoreStates transaction processing portfolio. There can
be no assurance that First Union will complete its acquisition of CoreStates
or, if
 
                                      19
<PAGE>
 
completed, that the Company could purchase the CoreStates transaction
processing portfolio on terms acceptable to the Company, if at all. There can
be no assurances as to the timing of such transactions. Further, there can be
no assurance that the First Union Alliance or the Crestar marketing
relationship will provide any other acquisition opportunities or that any such
acquisition opportunities can be completed on terms favorable to the Company,
if at all.
 
BANKING REGULATION
 
  As a result of First Union's ownership interest in the Company, the Company
has become subject to the Banking Laws. For example, the Company 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 KeyBank Joint Venture, the First Union Alliance and
the Firstar 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, the Company has agreed to notify,
and obtain approval from, First Union before the Company enters into any
business activities substantially different from the business activities the
Company currently conducts. Pursuant to the KeyBank Joint Venture and the
Firstar Joint Venture and to the extent required by the Banking Laws, the
Company may be required to take certain measures in the event either the
Company 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 the Company, 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,
the Company may not engage in the new business activity.
 
VISA AND MASTERCARD REGISTRATION TERMINATION
 
  The Company, along with all other nonbank transaction processors, 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. Through each of Regions Bank, Bank of the West, Mellon Bank,
Firstar, KeyBank and FUNB, which serve as member clearing banks for the
Company, the Company is registered with VISA and MasterCard as a certified
processor and member service provider. The Company's designation with VISA and
MasterCard as a certified processor and its status as a member service
provider are dependent upon the Company's continuing adherence to the
standards of the VISA and MasterCard credit card associations. These standards
are set by the respective member financial institutions of VISA and
MasterCard, some of which are competitors of the Company. In the event the
Company fails to comply with these standards, the Company's designation as a
certified processor or status as a member service provider could be suspended
or terminated. There can be no assurance that VISA and MasterCard will
maintain the Company's registrations or that the current VISA and MasterCard
rules allowing the Company and other nonbank transaction processors to market
and provide transaction processing services will remain in effect. The
termination of the Company's member service provider registrations or the
Company's status as a certified processor, or any changes in the VISA or
MasterCard rules that prevent the Company's registration or otherwise limit
the Company's ability to provide transaction processing and marketing services
for VISA or MasterCard, would have a material adverse effect on the Company's
financial condition and results of operations.
 
RISKS ASSOCIATED WITH ACQUISITION STRATEGY
 
  Increased Consolidation in the Marketplace. A material element of the
Company's growth strategy is the purchase of additional merchant portfolios
and acquisition of operating businesses and transaction processing assets in
order to facilitate growth, expand the Company's distribution channels and
create greater economies of scale. The Company faces significant competition
from other transaction processors for available acquisition,
 
                                      20
<PAGE>
 
joint venture and alliance opportunities. This competition has an impact on
the price and availability of acquisitions, joint ventures and alliances. In
addition, community and regional banks, whose transaction processing
businesses have been the Company's primary source of acquisition
opportunities, in recent years 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 the Company
or banks that have a relationship or alliance with one or more competitors of
the Company, thus potentially depriving the Company of acquisition
opportunities. There can be no assurance that the historical or current level
of acquisition opportunities will continue to exist, that the Company will be
able to acquire merchant portfolios, operating businesses and transaction
processing assets that satisfy the Company's criteria, or that any such
acquisition will be on terms favorable to the Company.
 
  Complexity of Risk Analysis of Acquisition Targets. In evaluating any
potential purchase of a merchant portfolio or joint venture, the Company
conducts a due diligence review of the related merchant portfolio. The review
process includes analyzing the composition of the merchant portfolio, applying
uniform standards and underwriting guidelines developed by the Company to the
merchant portfolio and attempting to identify high-risk merchants contained in
the merchant portfolio. Notwithstanding these due diligence efforts, however,
there can be no assurance that the Company will properly assess the risk
attributes associated with an acquired portfolio or otherwise identify high-
risk merchants. Incorrect risk assessments may result in excessive losses from
chargebacks or merchant fraud in connection with any acquired portfolio.
 
  Conversion of Purchased Portfolios. At the time of consummation of merchant
portfolio purchases or joint ventures, merchants in a purchased portfolio
typically are not operating on the NOVA Network and may not use the merchant
accounting processors used by the Company. Until the Company converts each
newly-purchased merchant to the NOVA Network and the Company's merchant
accounting processors, the Company has little, if any, control over the
performance of such other networks and processors and typically is unable to
apply fully its risk management and fraud avoidance practices to such
merchants. The Company also must continue to pay third parties for processing
services until the purchased portfolio is fully converted to the NOVA Network,
reducing the economic benefits to the Company during such time. Moreover, the
merchant customers that comprise a purchased portfolio may have been sold
transaction processing services by ISOs and financial institutions sponsored
by a principal member of the VISA and MasterCard credit card associations.
ISOs are independent agents that typically market and sell the full range of
transaction processing services to merchants, with such services primarily
being outsourced on a non-exclusive basis. Certain of these ISOs and financial
institutions may be unwilling to assist the Company in converting the
merchants to the NOVA Network and the Company's merchant accounting processors
and, in some cases, may solicit these merchants on behalf of a competing
processor. Further, the conversion of merchants may require that merchants
learn new operating procedures and could result in problems, causing merchants
to seek verbal authorization of credit and debit card transactions. As a
condition to conversion, merchants also may seek to negotiate lower fees.
 
  As a result of the recent purchases of merchant portfolios undertaken by the
Company, the magnitude, scope, timing, duration and expense of the conversion
of the KeyBank Joint Venture, the Firstar Joint Venture and the MBNA portfolio
will, in the aggregate, be greater than any conversion previously undertaken
by the Company, and there can be no assurance that the Company can
successfully complete these conversions in a timely manner, either
concurrently or in series. Failure to complete these conversions in accordance
with management plans could have a material adverse effect on the Company's
financial condition and results of operations. Further, the terms of the
KeyBank Joint Venture provide that if the Company does not complete
substantially the conversion of the KeyBank merchant portfolio by March 31,
1999, KeyBank may terminate the KeyBank Joint Venture, which could have a
material adverse effect on the Company's financial condition and results of
operations.
 
  The Company's acquisition strategy and the resulting growth will require
that the Company continue to attract and retain qualified personnel, while
concurrently expanding its managerial and operational infrastructure. There
can be no assurance that the Company will be able to hire and retain qualified
personnel or that the
 
                                      21
<PAGE>
 
Company will be able to expand successfully its infrastructure as appropriate
to accommodate future acquisitions or growth. The Company's acquisitions may
involve the hiring by the Company of certain management and sales personnel
affiliated with the acquired portfolio, and the failure to integrate
successfully such personnel into the Company's operations and business culture
may adversely affect the conversion process. As a result of any of these
factors and considerations, the Company may not realize the expected economic
benefits associated with its acquisitions, which may have a material adverse
effect on the Company's financial condition and results of operations.
 
  In connection with the formation of Key Merchant Services, the Company has
undertaken the conversion of merchant processing to the Company's operating
platform. In addition to the Company's normal conversion related expenses, the
Company expects to accrue a non-recurring charge of approximately $1.3
million, net of tax ($0.04 per share assuming dilution and prior to giving
effect to this offering), in the first quarter of 1998 principally to account
for early termination of a contract for merchant processing with a third party
processor.
 
  There can be no assurance that future acquisitions will not have an adverse
effect upon the Company's operating results, particularly in the fiscal
quarters immediately following the completion of such transactions, while the
operations of the acquired entities are converted and integrated into the
Company's operations. The Company's acquisition strategy will require
substantial capital resources, and is likely to result in the Company
incurring additional indebtedness. There can be no assurance that financing
for future acquisitions will be available or will be obtained on terms
favorable to the Company.
 
RISKS ASSOCIATED WITH JOINT VENTURE ALLIANCES
 
  The recently consummated joint venture alliances with each of Firstar and
KeyBank (collectively, the "Joint Ventures") present certain risks to the
Company in addition to the risks normally associated with portfolio
acquisitions which have been, and continue to be, a material element of the
Company's growth strategy. Because each of the Joint Ventures involved the
creation of a newly-formed limited liability company jointly-owned, managed
and serviced by the Company and Firstar or KeyBank, as the case may be,
continued cooperation with each of Firstar and KeyBank is important to the
success of the Joint Ventures. There can be no assurance that the Company's
relationships with each of Firstar and KeyBank will continue to be cooperative
and, accordingly, there can be no assurance that the Company will realize the
anticipated economic benefits from the Joint Ventures. Further, in the event
of a change in control of Firstar or KeyBank, there can be no assurance that
the resulting entity will support the Joint Ventures in the same manner and to
the same degree as its predecessor. The management and provision of processing
services to each of Elan Merchant Services and Key Merchant Services imposes
increased administrative, managerial and technological demands on the
Company's infrastructure and related systems, and there can be no assurance
that the Company will meet successfully such material demands and
requirements.
 
 
                                      22
<PAGE>
 
  Each of the Joint Ventures has been formed for a definitive term (subject in
each case to renewal provisions), but is subject to earlier termination by the
Company or Firstar or KeyBank, as the case may be, under a variety of
circumstances. In the event of earlier termination, or upon termination of
either of the Joint Ventures upon expiration of its term in the absence of
renewal, the then-current assets and merchant portfolio of such Joint Venture
are subject to "repurchase rights" by either the Company or Firstar or
KeyBank, as the case may be, depending on the circumstances of termination.
For example, each of the Joint Ventures imposes upon the Company certain
standards with respect to the performance of its processing services. In the
event such standards are breached by the Company, Firstar or KeyBank, as the
case may be, would have the right to purchase the Company's interest in Elan
Merchant Services or Key Merchant Services, respectively. Any such purchase
would likely result in a significant decrease in the number of merchant
locations served, and the aggregate sales volume processed, by the Company,
which may have a material adverse effect on the Company's financial condition
and results of operations. Further, in valuing the Joint Ventures, and
establishing a purchase price in connection therewith, the Company assumes the
continuance of the Joint Venture for a minimum term. Earlier termination may
result in the Company not realizing the anticipated economic and marketing
benefits from the Joint Venture, which may have a material adverse effect on
the Company's financial condition and results of operations.
 
FIRST UNION SHAREHOLDERS AGREEMENT
 
  Concurrently with the consummation of the First Union Alliance, the Company,
its shareholders and First Union entered into a Shareholders Agreement that
sets forth, among other things, agreements regarding the composition of the
Company's Board of Directors, the transferability of the Company's capital
stock and the Company's future business activities. In particular, the
Shareholders Agreement provides that the Company may, at its option, purchase
from First Union any merchant portfolios acquired by First Union through
whole-bank or other acquisitions. To facilitate First Union's compliance with
the banking laws, and to allow First Union to obtain any required consents or
approvals, the Company also has agreed to notify First Union before it enters
into, or acquires any company which is engaged in, business activities
substantially different from the business activities the Company currently
conducts. See "--Banking and Territorial Restrictions." If First Union is
unable to obtain such consents or approvals, the Company may not engage in the
new business activity or proceed with the contemplated acquisition.
Accordingly, the Company may be limited in its ability to seek or take
advantage of certain business opportunities or relationships which differ
substantially from the business activities the Company currently conducts.
Nevertheless, management believes that the synergies and other significant
benefits derived from the First Union Alliance offset the potential
limitations imposed by the banking laws.
 
MERCHANT ATTRITION
 
  The Company experiences attrition of its merchant base in the ordinary
course of business due to several factors, including business closures, losses
to competitors and conversion-related losses. In addition, substantially all
of the Company's contracts with its merchants may be terminated by either
party upon prior notice of 30 days or less. Increased merchant attrition may
have a material adverse effect on the Company's financial condition and
results of operations. There can be no assurance that the Company will not
experience higher rates of attrition in the future, particularly in connection
with acquired merchant portfolios.
 
DEPENDENCE ON MERCHANT ACCOUNTING RELATIONSHIPS
 
  The Company outsources certain merchant accounting services to Vital
Processing Services and Mellon Bank. 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. The failure of Vital Processing Services
and Mellon Bank to continue to perform these services efficiently and
effectively may adversely affect the Company's relationships with its merchant
customers and may result in the termination by merchants of their agreements
with the Company. The agreement with Vital Processing Services expires April
30, 1999, and the agreement with Mellon Bank expires June 30, 1999. The
Company currently is
 
                                      23
<PAGE>
 
negotiating a new agreement with Vital Processing Services. Termination of
either agreement would require the Company either to seek alternative
outsourcing arrangements or to make significant capital expenditures to
develop internal systems to provide these merchant accounting services.
Although management believes that in the event of termination of either or
both of these agreements the Company could locate alternative outsourcing
arrangements or develop internal systems, there can be no assurance that such
arrangements will be available on terms as favorable to the Company as the
existing contracts or that the Company could develop internal systems on a
timely or cost effective basis. Accordingly, termination of either agreement
could have a material adverse effect on the Company's financial condition and
results of operations.
 
ANNOUNCED INTERCHANGE RATE INCREASES
 
  Each of VISA and MasterCard has announced increases in interchange rates
effective in April 1998. The increase in rates of approximately 5% is the
largest single increase for either association since 1991. The announced
change affects all transaction processing industry competitors. While the
Company intends to reflect the entire amount of the increase in its pricing to
merchants, there can be no assurance that merchants will assume the entire
impact of the announced change or that transaction processing volumes and
merchant attrition will not be adversely affected by the change.
 
CHARGEBACK RISK
 
  When a billing dispute between a cardholder and a merchant is not resolved
in favor of the merchant, the transaction is "charged back" to the merchant
and that amount is credited to the cardholder. These billing disputes include,
among others: (i) nonreceipt of merchandise or services; (ii) unauthorized use
of a credit card; and (iii) general disputes between a customer and a merchant
as to the quality of the goods purchased or the services rendered by that
merchant. Some of the Company's merchant customers, including certain
merchants that generate high transaction processing volume, require full or
partial payment from debit and credit cardholders for products or services to
be delivered or rendered in the future. If the Company or its clearing banks
are unable to collect chargeback amounts from a merchant's account, and if the
merchant refuses or is unable due to bankruptcy or other reasons to reimburse
the Company for the chargeback, the Company bears the loss for the amount of
the refund paid to the cardholder. The Company attempts to reduce its exposure
to such losses by performing periodic credit reviews on its merchant customers
and adjusting the Company's rates based, in part, on the merchant's credit
risk, business or industry. There can be no assurance that the Company will
not experience significant losses from chargebacks in the future. Increases in
chargebacks not paid by merchants may have a material adverse effect on the
Company's financial condition and results of operations.
 
MERCHANT FRAUD
 
  The Company bears the risk of losses caused by fraudulent credit card
transactions initiated by its merchant customers. Examples of merchant fraud
include inputting false sales transactions or false credits. The Company
monitors merchant transactions against a series of standards it has developed
to detect merchant fraud. Notwithstanding these measures, however, there can
be no assurance that the Company will not experience significant amounts of
merchant fraud in the future, which may have a material adverse effect on the
Company's financial condition and results of operations.
 
TELECOMMUNICATIONS SERVICES PROVIDED BY WORLDCOM, INC.
 
  The Company has developed a proprietary telecommunications network, the NOVA
Network, and maintains an operating relationship with WorldCom. Pursuant to
its agreement with the Company, WorldCom provides long-distance and local
telecommunications access, as well as technical support, to the Company in
connection with the NOVA Network. This agreement expires February 28, 1999,
subject to earlier termination by the Company if WorldCom fails to meet
certain agreed-upon performance objectives. If the WorldCom agreement is
terminated or not renewed, the Company would be required to utilize the long-
distance and local telecommunications access of another long-distance
provider, which may increase the Company's expenses for network services,
resulting in a material adverse effect on the financial condition and results
of operations of the Company.
 
                                      24

CERTAIN STATE TAX ISSUES
 
  Transaction processing companies like the Company may be subject to state
taxation of certain portions of their fees charged to merchants for their
services. Application of this tax is an emerging issue in the industry and the
states have not yet adopted uniform guidelines implementing these regulations.
If the Company is required to pay such taxes and is unable to pass this tax
expense through to its merchant customers, the financial condition and results
of operations of the Company could be adversely affected.
 
DEVELOPMENT AND MARKET ACCEPTANCE OF NEW PRODUCTS
 
  Because the transaction processing industry and the software application
products and value-added services of the type offered by the Company have been
characterized by rapidly changing technology and the development of new
products and services, management believes that the future success of the
Company will depend, in part, on the Company's ability to continue to improve
its products and services and to offer its merchant customers new products and
services. There can be no assurance that the Company will continue to develop
successful new products and services or that the Company's newly-developed
products and services will perform satisfactorily or be widely accepted in the
marketplace.
 
FLUCTUATION IN QUARTERLY OPERATING RESULTS
 
  The Company has experienced and expects to continue to experience
significant seasonality in its business. The Company typically realizes 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. Quarterly results also are affected
by the timing of purchases of merchant portfolios and joint ventures and the
timing and magnitude of expenses for merchant portfolio conversions.
Fluctuations in operating results may result in volatility in the price of the
Common Stock.
 
DEPENDENCE ON KEY MANAGEMENT
 
  The development of the Company's business and its operations has been
materially dependent upon the active participation of its executive officers
and other key employees. The loss of one or more of the Company's executive
officers or other key employees may have a material adverse effect on the
Company's financial condition and results of operations.
 
SIGNIFICANT INTANGIBLE ASSETS
 
  A substantial portion of the Company's 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 such merchant portfolios or
business operations which would not be recovered from future cash flows, the
fair value and, as a result, the carrying value of the related intangible
asset will be reduced. Additionally, changes in accounting policies or rules
that affect the way in which such intangible assets are reflected in the
Company's financial statements, or the way in which they are treated for tax
purposes, could have a material adverse effect on the Company's financial
condition.
 
BANKING AND TERRITORIAL RESTRICTIONS
 
  To facilitate First Union's compliance with applicable banking laws,
regulations and orders (collectively, the "Banking Laws"), and to allow First
Union to obtain any required consents or approvals, the Company has agreed to
notify, and obtain approval from, First Union before the Company enters into
any business activities substantially different from the business activities
the Company currently conducts. See "First Union Shareholders Agreement."
Pursuant to the KeyBank Joint Venture and the Firstar Joint Venture and to the
extent required by the Banking Laws, the Company may be required to take
certain measures in the event either the Company 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 the Company, 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, the Company may not
 
                                      25
<PAGE>
 
engage in the new business activity (such restrictions, including the
restrictions relating to First Union, being collectively referred to herein as
the "Banking Restrictions").
 
  In connection with a December 1995 transaction between the Company and First
Union, the Crestar Alliance, the Firstar Joint Venture, and the KeyBank Joint
Venture, the Company agreed that it would not, without the prior consent of
the affected entity, enter into certain marketing or, in certain instances,
acquisition agreements with third parties located in specified areas where any
of First Union, Crestar Bank, Firstar or KeyBank maintain a significant
banking presence (such restrictions being collectively referred to herein as
the "Territorial Restrictions"). The effect of the Banking Restrictions and
the Territorial Restrictions is to limit in certain respects the Company's
ability to directly seek or take advantage of certain business or marketing
opportunities other than through a venture with the Company's regional bank
partners. The agreements generally do not prohibit the Company from pursuing
transactions indirectly through the respective alliance or joint venture.
 
CERTAIN ANTI-TAKEOVER PROVISIONS
 
  The Company's Articles of Incorporation authorize the Company to issue up to
5,000,000 shares of Preferred Stock with such designations, powers,
preferences and rights as may be fixed by the Board of Directors, without any
further vote or action by the shareholders. The issuance of Preferred Stock
could have the effect of delaying, deferring or preventing a change in control
of the Company.
 
POSSIBLE VOLATILITY OF STOCK PRICE
 
  Since the Company's initial public offering in May 1996, there has been and
may continue to be significant volatility in the market for the Common Stock,
and there can be no assurance that an active market for the Common Stock can
be sustained. See "Price Range of Common Stock." Factors such as changes in
quarterly operating results, the gain or loss of significant contracts, the
entry of new competitors into the Company's markets, changes in management,
announcements of technological innovations or new products by the Company or
its competitors, and general events and circumstances beyond the Company's
control could have a significant impact on the future market prices of the
Common Stock and the relative volatility of such market prices.
 
EMPLOYEES
 
  At March 19, 1998, the Company had 614 full-time employees, of which 227
were in sales and marketing, 293 were in operations and 94 were corporate and
general administrative employees. Of these employees, 212 were based in
Atlanta, Georgia at the Company's principal executive offices, 221 were based
in Knoxville, Tennessee at the Company's operations center, seven were based
in Arvada, Colorado, and ten were based in Jacksonville, Florida in connection
with the First Union Alliance. The Company's 227 sales and marketing employees
include 164 salespersons located throughout the United States, of whom 53 were
based at branches of banks with which the Company has formed Acquisition
Alliances. None of the Company's employees are represented by a collective
bargaining agreement nor has the Company ever experienced any work stoppage.
Management believes that the Company's relationship with its employees is
good.
 
ITEM 2. PROPERTIES
 
  The Company'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. The Company relocated its
principal executive offices in October 1996 to allow for the Company's
continued growth. In connection with this relocation, the Company transferred
certain of its operational functions, including the conversion management
functions, from Knoxville, Tennessee and Boulder, Colorado to Atlanta. The
Company's operations center is located in Knoxville, Tennessee and consists of
approximately 26,000 square feet. This facility is leased pursuant to a
sublease agreement scheduled to expire September 1, 2003. The Company leases
an additional 9,000 square feet adjacent to the operations center which houses
files and deployment and programming functions. Certain of the Company's
operations are conducted in facilities located in Jacksonville, Florida and
Arvada, Colorado consisting of approximately 9,360 and 3,040 square feet of
space, respectively. The Jacksonville space is being leased pursuant to an
agreement scheduled to expire in 1998. The
 
                                      26
<PAGE>
 
Arvada space is leased on a month to month basis. Certain of the Company's
employees also occupy other office facilities at various locations under
leases and various other agreements, which require aggregate payments that are
not material.
 
  In March 1998, NOVA Services Limited Partnership, a wholly-owned subsidiary
of the Company, purchased a 112,000 square-foot building in Knoxville,
Tennessee for $2.7 million. Prior to the Company's purchase of the property,
the facility was a retail shopping center. The Company intends to relocate its
current Knoxville operations center, as well as files, to approximately 84,000
square feet of space in the newly acquired facility. The remaining 28,000
square feet will be reserved for future expansion or sub-lease to third
parties. The conversion of the new facility into office space and the
relocation to the new facility are scheduled to be completed in the third
quarter of 1998. The deployment and programming functions will be relocated
from the adjacent facilities to the former operations center facility, and the
adjacent facilities will be reserved for future expansion or sub-lease to
third parties.
 
ITEM 3. LEGAL PROCEEDINGS
 
  The Company 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 the Company.
 
ITEM 4. SUBMISSION OF MATTERS TO A VOTE OF SECURITY HOLDERS
 
  No matter was submitted to a vote of the Company's shareholders during the
fourth quarter of the fiscal year ended December 31, 1997.

  RECENT SALES OF UNREGISTERED SECURITIES.
 
  On July 21, 1995, in connection with the acquisition of the bankcard

  In accordance with General Instruction G(3) of the Form 10-K, the
information relating to the directors of the Company, including directors who
are executive officers of the Company, is set forth under the caption

K and General Instruction G(3) of Form 10-K, information relating to the
executive officers of the Company 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 Securities Exchange Act of 1934:
Section 16(a) of the Securities Exchange Act of 1934, as amended, and
regulations of the Commission thereunder require the Company's directors and
executive officers and any persons who own more than 10% of the Company's
Common Stock, as well as certain affiliates of such persons, to file reports

Common Stock. Directors, executive officers and persons owning more than 10%
of the Company's Common Stock are required by Securities and Exchange
Commission regulations to furnish the Company with copies of all Section 16(a)
reports they file. Based solely on its review of the copies of such reports
received by it and representations that no other reports were required of
those persons, the Company believes that during fiscal 1997, all filing
requirements applicable to its directors and executive officers were complied
with in a timely manner except that Dr. James E. Carnes filed a late Form 3.

executive officers and their affiliates who own more than 10% of the Company's
Common Stock.

                                          ----------                     
Borrowing the Agent shall pay over such funds to the Borrower on the requested
Borrowing date.  All Borrowings shall be pro rata among the Lenders in
accordance with their respective Commitments.

     SECTION 3.4  Funding Reliance.  Unless the Agent shall have been notified
                  ----------------                                            
by telephone, confirmed in writing, by any Lender by 3:00 P.M., San Francisco
time, on the day prior to a Borrowing that such Lender will not make available
the amount which would constitute its Percentage of such Borrowing on the date
specified therefor, the Agent may assume, subject to the satisfactory
fulfillment by the Borrower of the conditions precedent set forth in Section 13,
                                                                     ----------
that such Lender has made such amount available to the Agent and, in reliance
upon such assumption, shall make available to the Borrower a corresponding
amount. If and to the extent that such Lender shall not have made such amount
available to the Agent, such Lender and the Borrower severally agree to repay
the Agent forthwith on demand such corresponding amount together with interest
thereon, for each day from the date the Agent made such amount available to the
Borrower to the date such amount is repaid to the Agent, at the interest rate
applicable at the time to Loans comprising such Borrowing.

     SECTION 3.5  Conversion and Continuation of Loans.  The Borrower may, by
                  ------------------------------------                       
delivery to the Agent of a Continuation/ Conversion Notice (herein called a
"Continuation/Conversion Notice") in the form of Exhibit C attached hereto with
                                                 ---------                     
appropriate insertions, before 10:00 A.M., San Francisco time, three Business

(a) convert Eurodollar Loans into Base Rate Loans, (b) convert Base Rate Loans
into Eurodollar Loans, and (c) continue any Eurodollar Loan into a subsequent
Interest Period of the same duration or of any other duration permitted
hereunder, subject to the following:

          (i)  the Interest Period applicable to any 

                                      -23-
<PAGE>
 
     Eurodollar Loan resulting from a conversion shall be specified by the
     Borrower in the Continuation/ Conversion Notice delivered pursuant to this
     Section; provided, however, that if no such Interest Period shall be
              --------  ------- 
     specified, the Borrower shall be deemed to have selected an Interest Period
     of one month's duration. If the Borrower shall not have given timely notice
     to continue any Loan into a subsequent Interest Period and shall not
     otherwise have given notice to convert such Loan, such Loan unless repaid
     pursuant to the terms hereof shall automatically be converted into a Base
     Rate Loan;

          (ii)  if less than all Loans at the time outstanding shall be
     converted or continued, such conversion or continuation shall be made pro
     rata among the Lenders, as applicable, in accordance with the respective
     principal amounts of Loans of such Type (and have the same Interest Period)
     held by such Lenders immediately prior to such conversion or continuation;

          (iii)  in the case of a conversion or continuation of less than all
     Loans, the aggregate principal amount of such Loans converted or continued
     shall be not less than $100,000 or any larger integral multiple of $50,000;

          (iv)  if any Eurodollar Loan is converted at a time other than the
     last day of an Interest Period applicable thereto, the Borrower shall at
     the time of conversion pay any loss or expense (including, without
     limitation, breakage losses and expenses) associated therewith pursuant to
     Section 7.5;
     ----------- 

          (v)  any portion of a Loan maturing or required to be repaid in less
     than one month may not be converted into, or continued as, a Eurodollar
     Loan; and

          (vi)  any portion of a Eurodollar Loan required to be paid on any
     principal payment date occurring in less than one month after the end of
     the then-current Interest Period applicable to such Loan shall be
     automatically converted at the end of such Interest Period into a Base Rate
     Loan.

Notwithstanding the foregoing, so long as any Default shall exist, no Loans
shall be converted into Eurodollar Loans or continued as Eurodollar Loans into a
subsequent Interest Period.

                  -----------------------------------                        
pursuant to Section 6.3, the aggregate principal amount of Revolving Loans shall
            -----------                                                         
be payable (and the Borrower agrees to pay such aggregate outstanding principal
amount of Revolving Loans) in eight consecutive equal principal installments on
each Quarterly Payment Date commencing on December 31, 2000, and to and
including the Revolving Termination Date, each such installment to be equal to
1/8th of the amount by which on the Revolving Conversion Date, the aggregate
principal amount of Revolving Loans plus the LC Amount exceeds $50,000,000 (the
principal of the Revolving Loans equal to the amount of such excess being herein
called the "Converted Revolving Loans"), except that the installment on the
Revolving Termination Date shall be in the aggregate unpaid principal amount of
all Revolving Loans outstanding on such date.  The Revolving Loans of each
Lender shall be evidenced by a Revolving Note, respectively, payable to the
order of such Lender in the principal amount of the Revolving Loan Commitment of
such Lender (or, if less, in the aggregate unpaid principal amount of all of
such Lender's Revolving Loans hereunder outstanding on the Revolving Termination
Date).

     SECTION 3.8  Recordkeeping.  Each Lender shall record in its records, or at

its option on the schedule attached to its relevant Note, the date and amount of
each Loan made by such Lender, each repayment or conversion thereof, and in the
case of each Eurodollar Loan the dates on which each Interest Period for such
Loan shall begin and end. The information so recorded shall be rebuttable
presumptive evidence of the accuracy thereof. The failure to so record any such
information or any error in so recording any such information shall not,
however, limit or otherwise affect the obligations of the Borrower hereunder or
under any Note to repay the principal amount of the Loans together with all
interest accruing thereon.

                       SECTION 4.  THE LETTERS OF CREDIT

     SECTION 4.1  Request for Issuance of Letters of Credit.  (a) The Borrower
                  -----------------------------------------                   
shall give the Agent and the Issuing Lender at least five Business Days' prior
written notice of a request for issuance of each Letter of Credit, each such
request to be accompanied by an application substantially in the form of Exhibit
                                                                         -------
D (an "LC Application") duly executed by the Borrower and in all respects in
- -                                                                           
form and substance satisfactory to the Agent and the Issuing Lender, together
with such other documentation as the Agent or the Issuing Lender may request in
support thereof.  The Agent shall promptly notify each Lender of the Borrower's
request that such Letter of Credit be issued.

     (b) It is hereby agreed that, notwithstanding the execution by Borrower of
any printed form letter of credit application (the "Application") used by the
Issuing Lender from time to time in connection with the issuance of Letters of
Credit hereunder, this Agreement, and not any such Application shall govern (i)
the time and amount of payment of principal and interest, fees and commissions,
and any other charges, reimbursements or adjustments, (ii) standards of conduct
and liability, (iii) the occurrence of defaults and acceleration of
indebtedness, (iv) notices and communications, and (v) "Collateral" (as defined
in the Application) and any rights with respect to any such Collateral; and
otherwise in the case of any conflict or inconsistency whatsoever between this
Agreement and any such Standby Credit Agreement, this Agreement shall control in
all respects.

     SECTION 4.2  Expiration and other Terms.  Each Letter of Credit shall
                  --------------------------                              
expire on or before the date which is the earlier of one year following the
issuance of such Letter of Credit or thirty days prior to the Revolving
Termination Date unless the Borrower shall have pledged cash collateral to the
Agent therefore in an amount, and pursuant to documentation reasonably
satisfactory to each Lender, the Issuing Lender and the Agent.

     SECTION 4.3  Participation.  Concurrently with the issuance of each
                  -------------                                 
Letter of Credit, the Issuing Lender shall be deemed to have sold and
transferred to each other Lender, and each Lender shall be deemed irrevocably
and unconditionally to have automatically purchased and received from the
Issuing Lender, without recourse or warranty, an undivided interest and
participation, to the extent of such other Lender's Percentage, in such Letter
of Credit and the Borrower's related LC Obligations and any security therefor.

                                      -26-
<PAGE>
 
     SECTION 4.4  Notification of Demand for Payment.  The Issuing Lender shall
                  ----------------------------------                           
promptly notify the Agent (who shall in turn promptly notify the Borrower and
each Lender) of the amount of each demand for payment under a Letter of Credit
and of the date on which such payment is to be made.

     SECTION 4.5  Funding by Issuing Lender.  With respect to each demand for
                  -------------------------                                  
payment pursuant to a Letter of Credit, the Issuing Lender shall, promptly
following its receipt thereof, examine all documents purporting to represent
such demand to ascertain that the same appear on their face to be in conformity
with the terms and conditions of such Letter of Credit.  If the Issuing Lender
determines that a demand for payment under a Letter of Credit conforms to the
terms and conditions of such Letter of Credit, then the Issuing Lender shall
make payment to the Beneficiary in accordance with the terms of such Letter of
Credit.

     SECTION 4.6  Funding By Lenders.  If the Issuing Lender makes any payment
                  ------------------                                          
under any Letter of Credit and the Borrower has not reimbursed the Issuing
Lender in full for such payment on the date on which payment is made under a
Letter of Credit, or if any reimbursement received by the Issuing Lender from
the Borrower is or must be returned or rescinded upon or during any bankruptcy
or reorganization of the Borrower or otherwise, each Lender, promptly upon
notice, shall make available to the Agent, for the account of the Issuing Lender
in Dollars and in same day funds, such Lender's Percentage of the amount of such
payment.  If and to the extent any Lender shall not have made such amount
available to the Agent on any such date, such Lender agrees to pay interest on
such amount to the Agent for the account of the Issuing Lender forthwith on
demand for each day from and including the date on which such payment was to be
made to but excluding the date such amount is made available to the Agent for
the account of the Issuing Lender.  Such interest shall be determined at a rate
per annum equal to the Federal Funds Rate from time to time in effect, based
upon a year of 360 days.  Any Lender's failure to make available to the Agent
its Percentage of any payment under a Letter of Credit shall not relieve any
other Lender of its obligation to make available to the Agent its Percentage of
such payment on the date such payment is to be made, but no Lender shall be
responsible for the failure of any other Lender to make available to the Agent
such other Lender's Percentage of any such payment.

     SECTION 4.7  Non-Conforming Demand For Payment.  If, after examination of a
                  ---------------------------------                             
demand for payment under a Letter of Credit, the Issuing Lender shall have
determined that such demand does not conform to the terms and conditions of such
Letter of Credit, 

                                      -27-
<PAGE>
 
then the Issuing Lender shall, as soon as reasonably practicable, give notice to
the related Beneficiary and to the Borrower to the effect that demand was not in
accordance with the terms and conditions of such Letter of Credit, stating the
reasons therefor and that the relevant document is being held at the disposal of
the Beneficiary or is being returned to the Beneficiary, as the Issuing Lender
may elect. The Beneficiary may attempt to correct any such non-conforming demand
for payment under such Letter of Credit if, and to the extent that, the
Beneficiary is entitled (without regard to the provisions of this sentence) and
able to do so.

     SECTION 4.8  Return of Funds Related to Non-Conforming Demand.  If the
                  ------------------------------------------------         
Issuing Lender does not disburse funds to the Beneficiary for any reason after
having received such funds from any Lender pursuant to Section 4.6, the Issuing
                                                       -----------             
Lender shall return such funds to such Lender on the next following Business Day
together with interest on such funds from and including the date on which the
Issuing Lender received such funds to but excluding the day on which the Issuing
Lender so returns such funds at the Federal Funds Rate for each such day, based
upon a year of 360 days.

     SECTION 4.9  Return of Letter of Credit.  With respect to each Letter of
                  --------------------------                                 
Credit, the Issuing Lender shall have the right, provided the Issuing Lender is
not then in default under such Letter of Credit by reason of its having
wrongfully failed to honor a demand for payment previously made by Beneficiary
under such Letter of Credit, to require the Beneficiary to surrender such Letter
of Credit to the Issuing Lender on the stated expiration date.  The Borrower
agrees, if necessary, to use its best efforts (which shall not include the
incurrence of costs outside the ordinary course of business) to cause the
Beneficiary to surrender such Letter of Credit.

     SECTION 4.10  Reimbursement Agreement of the Borrower.  The Borrower hereby
                   ---------------------------------------                      
unconditionally and irrevocably agrees to reimburse the Issuing Lender,
immediately upon demand, for each payment made by the Issuing Lender under a
Letter of Credit honoring a demand for payment made by the Beneficiary
thereunder, with interest on the amount so paid by the Issuing Lender from and
including the date paid by the Issuing Lender to but not including the date the
Issuing Lender is reimbursed therefor, at a rate per annum equal to the
Alternate Base Rate from time to time in effect (but not less than the Alternate
Base Rate in effect on the date of such payment by the Issuing Lender) plus 1.0%
per annum. Interest shall be computed for the actual number of days elapsed on
the basis of a year consisting of 360 days. Upon receipt of each payment under
this Section 4.10, the Issuing 
     ------------                          

                                      -28-

Lender shall promptly pay to each Lender which previously made the entire
payment required under Section 4.6, in Dollars and in the kind of funds
                       ----------- 
received, an amount equal to such Lender's Percentage of such received payment.

     SECTION 4.11  Obligation to Reimburse for or Participate in Letter of
                   -------------------------------------------------------
Credit Payments.  The Borrower's obligation to reimburse the Issuing Lender for
- ---------------                                                                
payments made by the Issuing Lender under any  Letter of Credit honoring a
demand for payment by the Beneficiary thereunder, and each Lender's obligation
to participate in and make available to the Issuing Lender its Percentage of
such payments in accordance with this Agreement, shall be irrevocable, absolute
and unconditional under any and all circumstances including, without limitation,
any of the following circumstances:

          (a)  any lack of legality, validity, regularity or enforceability of
     this Agreement, any Letter of Credit or any other Related Document;

          (b)  the existence of any claim, setoff, defense or other right which
     the Borrower may have or have had at any time against any Beneficiary, the
     Agent, the Issuing Lender, any other Lender, any transferee of any Letter
     of Credit (or any Person for whom any such transferee may be acting) or any
     other Person, whether in connection with this Agreement, any Letter of
     Credit, the transactions contemplated herein or any unrelated transactions
     (including any underlying transaction between the Borrower and the
     Beneficiary of any Letter of Credit);

          (c)  any draft, certificate or any other document presented under any
     Letter of Credit proving to be forged, fraudulent, invalid or insufficient
     in any respect or any statement therein being untrue or inaccurate in any
     respect;

          (d)  the surrender or impairment of any security for the performance
     or observance of any of the terms of any of the Related Documents;

          (e)  payment by the Issuing Lender under any Letter of Credit against
     presentation of a draft or certificate or other document that does not
     comply with the terms of such Letter of Credit unless such payment by the
     Issuing Lender constituted gross negligence or willful misconduct of the
     Issuing Lender; or

                                      -29-
<PAGE>
 
          (f)  the occurrence of any Default or Event of Default;

     provided, however, that the Borrower shall not be obligated to reimburse
     --------  ------- 
     the Issuing Lender for, and no Lender shall be obligated to participate in,
     any wrongful payment made by the Issuing Lender under any Letter of Credit
     as a result of acts or omissions constituting gross negligence or willful
     misconduct on the part of the Issuing Lender or any of its officers,
     employees or agents.

     SECTION 4.12  Mandatory Payment to Agent of LC Obligations.  The Borrower
                   --------------------------------------------

the Agent in a separate collateral account, bearing interest for the account of
the Borrower, as security for the LC Obligations and other Liabilities) plus the
then aggregate accrued amount of unpaid fees arising under Section 5.7(c).

     Lender for the period (including any portion thereof when any of its
     Commitments are suspended by reason of the Borrower's inability to satisfy
     any condition of Section 13) commencing on the Effective Date and

     "Commitment Fee") at a rate per annum equal to the Applicable Commitment
     Fee Rate on such Lender's Percentage of the average daily unused portion of
     Revolving Loan Commitments (such unused portion at any time being equal to
     the amount of the Revolving Loan Commitment minus the aggregate principal
     amount of Revolving Loans then outstanding minus the then LC Amount).  Such
     Commitment Fees shall be payable by the Borrower in arrears on each
     Quarterly Payment Date, commencing with the first such day following the
     Effective Date, and on the Revolving Termination Date.

          (b)  The Borrower agrees to pay to Agent all fees set forth in that
     certain fee letter dated as of October 27, 1997 herewith between the
     Borrower and Agent.

          (c)  The Borrower agrees to pay (i) to the Agent for the account of
     each Lender a Commitment Fee for each Letter of Credit (the "LC Commitment
     Fee"), from the date of issuance thereof to the earlier to occur of the
     expiration or termination thereof or the date of payment by the Agent
     thereunder, at a rate per annum equal to the Applicable LC Fee Rate
     (provided that if any Default or Event of Default exists, such fee shall be
     at a rate equal to 2.0% per annum above the rate otherwise in effect),
     times the aggregate outstanding amount of each such Letter of Credit, such
     fee to be payable in arrears on the Quarterly Payment Date (or at such
     other times as the Agent shall request, for any period prior to such date
     or time for which such Commitment Fee shall not have been theretofore paid)
     and (ii) to the Issuing Lender an acceptance commission (the "Acceptance
     Commission") for each Letter of Credit at a rate equal to 0.075% times the
     aggregate face amount of each such Letter of Credit, such fee to be payable
     upon issuance of the respective Letter of Credit and from time to time on
     demand the normal issuance, presentation, amendment and other processing
     fees, and other standard costs and charges, of the Issuing Bank relating to
     Letters of Credit as from time to time in effect.

          (d)  Concurrent with the execution and delivery of this Agreement, the
     Borrower agrees to pay directly to the Agent for the account of the Lenders
     prorata according to their respective Percentages, a Facility Fee equal to
     0.10% of the Aggregate Commitment.

All such fees shall be computed for the actual number of days elapsed on the
basis of a 360-day year without regard to any Default or Event of Default.

Subsidiary shall sell, assign, lease, transfer, contribute, convey or otherwise
dispose of (any of the foregoing being a "Disposition") any of its assets, other
than a disposition made in accordance with Section 11.4, the Borrower shall
                                           ------------

$50,000,000.

     (b)  Each repayment of the Revolving Loans pursuant to Section 6.3 shall

automatically reduce the Revolving Loan Commitments by a like amount.

     (c)  Each reduction of the Revolving Loan Commitments shall be prorata
among the Lenders according to their respective Percentages.

     SECTION 6.5  Making of Payments.  Except as otherwise provided, all
                  ------------------

sole account of, the Agent.

     SECTION 6.6  Application of Payments.  Subject to Sections 6.2 and 6.3, so
                  -----------------------              ------------     ---    
long as no Default shall exist or result therefrom, any payment (including any
prepayment) of principal or interest shall be applied to such Revolving Loans as
the Borrower shall direct in a notice to the Agent (or, absent such a notice, as
the Agent shall determine in its discretion).

     SECTION 6.7  Due Date Extension.  If any payment provided for hereunder
                  ------------------                                        
falls due on a Saturday, Sunday or other day which is not a Business Day, then
such due date shall be extended to the next following Business Day (except as
provided in the last sentence of Section 5.4), and additional interest shall
                                 -----------                                
accrue and be payable for the period of such extension.

     SECTION 6.8  Sharing of Payments.  (a) If any Lender shall obtain any
                  -------------------                                     
payment or other recovery (whether voluntary, involuntary, by application of
offset or otherwise) on account of any Loan or LC Obligation (other than
pursuant to the terms of Section 7) in excess of its pro rata share (based on
                         ---------                                           
its Percentage) of payments and other recoveries obtained by all Lenders of
Loans or LC Obligations on account of principal of and interest on Loans or
reimbursement or fees with respect to LC Obligations then held by them, such
Lender shall purchase from the other Lenders such participation in the Loans and
LC Obligations held by them as shall be necessary to cause such purchasing
Lender to share the excess payment or other recovery ratably with each of them;
provided, however, that if all or any portion of the excess payment or other
- --------  -------                                                           
recovery is thereafter recovered from such purchasing Lender, the purchase shall
be rescinded and each Lender which has sold a participation to the 

                                      -35-
<PAGE>
 
purchasing Lender shall repay to the purchasing Lender the purchase price to the
ratable extent of such recovery together with an amount equal to such selling
Lender's ratable share (according to the proportion of (i) the amount of such
selling Lender's required repayment to the purchasing Lender to (ii) the total
amount so recovered from the purchasing Lender) of any interest or other amount
paid or payable by the purchasing Lender in respect of the total amount so
recovered.

     (b)  The Borrower agrees that any Lender so purchasing a participation from
another Lender pursuant to Section 6.8(a) may, to the fullest extent permitted
                           --------------                                     
by law, exercise all its rights of payment (including pursuant to Section 6.9)
                                                                  ----------- 
with respect to such participation as fully as if such Lender were the direct
creditor of the Borrower in the amount of such participation.  If under any
applicable bankruptcy, insolvency or other similar law, any Lender receives a
secured claim in lieu of a setoff to which this Section applies, such Lender
shall, to the extent practicable, exercise its rights in respect to such secured
claim in a manner consistent with the rights of the Lenders entitled under this
Section to share in the benefits of any recovery of such secured claim.

     SECTION 6.9  Setoff.  Each Lender shall, upon the occurrence of any Event
                  ------                                                      
of Default described in Section 14.1.1 or Section 14.1.3 or, with the consent of
                        --------------    --------------                        
the Required Lenders, upon the occurrence of any other Event of Default, have
the right to appropriate and apply to the payment of the Liabilities owing to it
(whether or not then due), and (as security for such Liabilities) the Borrower
hereby grants to each Lender a continuing security interest in, any and all
balances, credits, deposits, accounts or moneys of the Borrower then or
thereafter maintained with such Lender.  Any such appropriation and application
shall be subject to the provisions of Section 6.8.  Each Lender agrees promptly
                                      -----------                              
to notify the Borrower and the Agent after any such setoff and application made
by such Lender; provided, however, that the failure to give such notice shall
                --------  -------                                            
not affect the validity of such setoff and application.  The rights of each
Lender under this Section are in addition to other rights and remedies
(including other rights of setoff under applicable law or otherwise) which such
Lender may have.

     SECTION 6.10  Unconditional Payment.  The Borrower is and shall be
                   ---------------------                               
obligated to pay principal, interest and any and all other amounts which become
payable hereunder or under the other Related Documents (hereinafter referred to
as "Payments") without abatement, postponement, diminution or deduction, and
free and clear of, and without deduction for, any and all present and future
taxes, levies, imposts, duties, fees, charges, deductions 

                                      -36-
<PAGE>
 
or withholdings of any nature (hereinafter referred to as "Deductions"). In the
event that the laws of the United States or of any state in the United States
require withholding of any Deductions from Payments to be delivered to any
Lender (other than the Agent), then the Agent shall withhold from portions of
the Payments delivered by the Agent to any such Lender the sums required by law
to be so withheld, and Borrower agrees to pay the full amount of all Payments to
the Agent.

     Notwithstanding the foregoing, in the event the Agent is also a Lender
hereunder and in the event that Borrower is required to withhold Deductions from
Payments made to Agent on account of Agent's monetary participation as Lender in
the Loans, as opposed to its role as Agent, then Borrower shall withhold such
Deductions from Payments owing to Agent for its own account.  In the event that
Agent is organized under the laws of a jurisdiction other than the U.S., prior
to the due date of any payments under the Loans or LC Obligations, Agent shall
deliver to the Borrower, on or about the first scheduled payment date in each
calendar year, a United States Internal Revenue Service Form 4224 or Form 1001,
as may be applicable (or any successor form), appropriately completed.


                      SECTION 7.  CHANGES IN CIRCUMSTANCES

     SECTION 7.1  Increased Costs.  If (a) Regulation D of the Board of
                  ---------------                                      
Governors of the Federal Reserve System, or (b) after the date hereof, the
adoption of any applicable law, rule or regulation, or any change therein, or
any change in the interpretation or administration thereof by any governmental
authority, central bank or comparable agency charged with the interpretation or
administration thereof, or compliance by any Lender (or any Lending Office of
such Lender) with any request or directive (whether or not having the force of
law) or any such authority, central bank or comparable agency,

          (i)  shall subject any Lender (or any Lending Office of such Lender)
     to any tax, duty or other charge with respect to its Eurodollar Loans, its
     Loans or its LC Obligations or its obligation to make Eurodollar Loans, or
     issues Letters of Credit or shall change the basis of taxation of payments
     to any Lender of the principal of or interest on its Eurodollar Loans or
     any other amounts due under this Agreement in respect of its Eurodollar
     Loans or its obligation to make Eurodollar Loans or its LC Obligations
     (except for changes in the rate of Tax, other than Taxes covered by Section
                                                                         -------

     on the overall gross or net income of such Lender or its Lending Office);
     or

          (ii)  shall impose, modify or deem applicable any reserve (including,
     without limitation, any reserve imposed by the Board of Governors of the
     Federal Reserve System, but excluding any reserve included in the
     determination of interest rates pursuant to Section 5 or in the definition
                                                 ---------
     of Eurodollar Rate (Reserve Adjusted)), special deposit or similar
     requirement against assets of, deposits with or for the account of, or
     credit extended by, any Lender (or any Lending Office of such Lender); or

          (iii)  shall impose on any Lender (or its Lending Office) any other
     condition affecting its Eurodollar Loans or its LC Obligations;

and the result of any of the foregoing is to increase the cost to (or in the
case of Regulation D referred to above, to impose a cost on) such Lender (or any
Lending Office of such Lender) of making or maintaining any Eurodollar Loan, or
any Letter of Credit or participation therein or to reduce the amount of any sum
received or receivable by such Lender (or the Lending Office or such Lender)
under this Agreement or under its Loans with respect thereto, then within thirty
days after demand by such Lender (which demand shall be accompanied by a
statement setting forth the basis of such demand), the Borrower shall pay
directly to such Lender such additional amount or amounts as will compensate
such Lender for such increased cost or such reduction.

     SECTION 7.2  Change in Rate of Return.  If any change in, or the
                  ------------------------                           
introduction, adoption, effectiveness, interpretation, reinterpretation or
phase-in of, any law or regulation, directive, guideline, decision or request
(whether or not having the force of law) of any court, central bank, regulator
or other governmental authority having jurisdiction over any Lender affects or
would affect the amount of capital required or expected to be maintained by such
Lender or any person controlling such Lender, and such Lender reasonably
determines that the rate of return on its or such controlling person's capital
as a consequence of its Commitments, the Loans or the Letters of Credit made by
such Lender (or any participating interest therein held by such Lender) is
reduced to a level below that which such Lender or such controlling person could
have achieved but for the occurrence of any such circumstance, then, in any such
case the Borrower shall, within thirty days after demand by such Lender to the
Borrower of a written request therefor, pay directly to such Lender additional
amounts sufficient to compensate such Lender or such controlling person

                                      -38-
<PAGE>
 
for such reduction in rate of return. A statement of such Lender as to any such
additional amount or amounts (including calculations thereof in reasonable
detail) shall, in the absence of manifest error, be conclusive and binding on
the Borrower. In determining such amount, such Lender may use any method of
averaging and attribution that it shall deem reasonably applicable. Each Lender
shall notify the Borrower of any event of which it has knowledge, occurring
after the date hereof, which will entitle such Lender to compensation pursuant
to this Section 7.2.
        ----------- 

     SECTION 7.3  Basis for Determining Interest Rate Inadequate or Unfair.  If
                  --------------------------------------------------------     
with respect to any Interest Period:

          (a)  the Agent determines that deposits in Dollars (in the applicable
     amounts) are not being offered to BofA in the relevant market for such
     Interest Period, or the Agent otherwise determines (which determination
     shall be binding and conclusive on all parties) that by reason of
     circumstances affecting the interbank eurodollar market adequate and
     reasonable means do not exist for ascertaining the applicable Eurodollar
     Rate; or

          (b)  any Lender advises the Agent that the Eurodollar Rate (Reserve
     Adjusted) as determined by the Agent, will not adequately and fairly
     reflect the cost to such Lender of maintaining or funding such Loans for
     such Interest Period, or that the making or funding of Eurodollar Loans has
     become impracticable as a result of an event occurring after the date of
     this Agreement which in the opinion of such Lender materially changes such
     Loans,

then, so long as such circumstances shall continue:  (i) the Agent shall
promptly notify the other parties thereof, (ii) no Lender shall be under any
obligation to make or convert into Eurodollar Loans so affected, and (iii) on
the last day of the then current Interest Period for Loans of the Type so
affected, such Loans shall, unless then repaid in full, automatically  convert
to Base Rate Loans.  If conditions subsequently change so that the foregoing
conditions no longer exist, the Agent in the case of clause (A) or such Lender
in the case of clause (B) will promptly notify the Borrower and the Lenders
thereof, and upon the receipt of such notice, the obligations of all Lenders to
make or continue Eurodollar Loans shall be reinstated.

     SECTION 7.4  Changes in Law Rendering Certain Loans Unlawful.  In the event
                  -----------------------------------------------               
that any change in (including the 

                                      -39-

adoption of any new) applicable laws or regulations, or any change in the
interpretation of applicable laws or regulations by any governmental or other
regulatory body charged with the administration thereof, should make it unlawful
for a Lender or the Lending Office of such Lender ("Affected Lender") to make,
maintain or fund a Type of Eurodollar Loans, then (a) the Affected Lender shall
promptly notify each of the other parties hereto, (b) the obligation of all
Lenders to make or convert into the Type of Eurodollar Loans made unlawful for
the Affected Lender shall, upon the effectiveness of such event, be suspended
for the duration of such unlawfulness, and (c) on the last day of the current
Interest Period for Eurodollar Loans (or, in any event, if the Affected Lender
so requests, on such earlier date as may be required by the relevant law,
regulation or interpretation), the Eurodollar Loans shall, unless then repaid in
full, automatically convert to Base Rate Loans. If conditions subsequently
change so that the foregoing conditions no longer exist, such Lender will
promptly notify the Borrower and the other Lenders thereof, and upon the receipt
of such notice, the obligations of all Lenders to make or continue Eurodollar
Loans shall be reinstated.

     SECTION 7.5  Funding Losses.  The Borrower hereby agrees that upon written
                  --------------                                               
demand by any Lender with a copy to Agent (which demand shall be accompanied by
a statement setting forth the basis for the calculations of the amount being
claimed) the Borrower will indemnify such Lender against any net loss or expense
which such Lender may sustain or incur (including, without limitation, any net
loss or expense incurred by reason of the liquidation or reemployment of
deposits or other funds acquired by such Lender to fund or maintain Eurodollar
Loans, but not including lost profits), as reasonably determined by such Lender,
as a result of (a) any payment or prepayment or conversion of any Eurodollar
Loan of such Lender on a date other than the last day of an Interest Period for
such Loan, or (b) any failure of the Borrower to borrow or convert any Loans on
a date specified therefor in a Borrowing Request or Continuation/Conversion
request pursuant to this Agreement.  For this purpose, all notices to the Agent
pursuant to this Agreement shall be deemed to be irrevocable.

     SECTION 7.6  Right of Lenders to Fund Through Other Offices.  Each Lender
                  ----------------------------------------------

such Lender and the obligation of the Borrower to repay such Loan shall

such Loan, for the account of such branch or

Notwithstanding any provision of this Agreement to the contrary, each Lender
shall be entitled to fund and maintain its funding of all or any part of its
Loans in any manner it sees fit, it being understood, however, that for the
purposes of this Agreement all determinations hereunder shall be made as if such
Lender had actually funded and maintained each Eurodollar Loan during each
Interest Period for such Loan through the purchase of deposits having a maturity
corresponding to such Interest Period and bearing an interest rate equal to the
Eurodollar Rate, as the case may be, for such Interest Period.

     SECTION 7.8  Avoidance of Additional Cost.  If at any time the Borrower is
                  ----------------------------

efforts to transfer its rights and obligations hereunder to another Lending
Office of such Affected Lender, and to take such other steps as may be
available, so that the payment under Section 7.1 or 7.2 would no longer be
                                     -----------    ---

of 30 days the efforts referred to in clause (i) have not been made or have not

been successful, then, on request by the Borrower, such Affected Lender shall
pursuant to Section 16.1 make all reasonable efforts to transfer at par (or less
            ------------                                                        
than par if concurrently with such transfer the Borrower shall fully reimburse
such Affected Lender for any loss to such Affected Lender arising from such
transfer at less than par), its rights and obligations hereunder to another
lender or financial institution (which shall, in any event, be an Eligible
Assignee) satisfactory to the Borrower and the Agent, such transfer to be
pursuant to documentation satisfactory to the Borrower and the Agent.
Notwithstanding the foregoing, no Affected Lender shall be required under this

law or regulations or with such Affected Lenders's internal policies, (b) in the
judgment of such Affected Lender, would be disadvantageous to such Affected
Lender.  The Borrower shall use its reasonable efforts to cooperate with any
efforts by an Affected Lender to take action pursuant to this Section 7.8.

herein, nor shall the Agent have or be deemed to have any fiduciary relationship
with any Lender, and no implied covenants, functions, responsibilities, duties,
obligations or liabilities shall be read into this Agreement or any other Loan
Document or otherwise exist against the Agent.  Without limiting the generality
of the foregoing sentence, the use of the term "agent" in this Agreement with
reference to the Agent is not intended to connote any fiduciary or other implied
(or express) obligations arising under agency doctrine of any applicable law.
Instead, such term is used merely as a matter of market custom, and is intended
to create or reflect only an administrative relationship between independent
contracting parties.

     (b) The Issuing Lender shall act on behalf of the Lenders with respect to
any Letters of Credit Issued by it and the documents associated therewith until
such time and except for so long as the Agent may agree at the request of the
Required Lenders to act for such Issuing Lender with respect thereto; provided,
                                                                      -------- 
however, that the Issuing Lender shall have all the benefits and immunities (i)
- -------                                                                        
provided to the Agent in this Section 15 with respect to any acts taken or
omissions suffered by the Issuing Lender in connection with Letters of Credit
Issued by it or proposed to be Issued by it and the application and agreements
for letters of credit pertaining to the Letters of Credit as fully as if the
term "Agent," as used 

                                      -70-
<PAGE>
 
in this Section 15, included the Issuing Lender with respect to such acts or
omissions, and (ii) as additionally provided in this agreement with respect to
the Issuing Lender.

     SECTION 15.2  Delegation of Duties.  The Agent may execute any of its
                   --------------------                                   
duties under this Agreement or any other Loan Document by or through agents,
employees or attorneys-in-fact and shall be entitled to advice of counsel
concerning all matters pertaining to such duties. The Agent shall not be
responsible for the negligence or misconduct of any agent or attorney-in-fact
that it selects with reasonable care.

     SECTION 15.3  Liability of Agent.  None of the Agent-Related Persons shall
                   ------------------                                          
(i) be liable for any action taken or omitted to be taken by any of them under
or in connection with this Agreement or any other Loan Document or the
transactions contemplated hereby (except for its own gross negligence or willful
misconduct), or (ii) be responsible in any manner to any of the Lenders for any
recital, statement, representation or warranty made by the Borrower or any
Subsidiary or Affiliate of the Borrower, or any officer thereof, contained in
this Agreement or in any other Loan Document, or in any certificate, report,
statement or other document referred to or provided for in, or received by the
Agent under or in connection with, this Agreement or any other Loan Document, or
the validity, effectiveness, genuineness, enforceability or sufficiency of this
Agreement or any other Loan Document, or for any failure of the Borrower or any
other party to any Loan Document to perform its obligations hereunder or
thereunder.  No Agent-Related Person  shall be under any obligation to any
Lender to ascertain or to inquire as to the observance or performance of any of
the agreements contained in, or conditions of, this Agreement or any other Loan
Document, or to inspect the properties, books or records of the Borrower or any
of the Borrower's Subsidiaries or Affiliates.

     SECTION 15.4  Reliance by Agent.  (a)  The Agent shall be entitled to rely,
                   -----------------                                            
and shall be fully protected in relying, upon any writing, resolution, notice,
consent, certificate, affidavit, letter, telegram, facsimile, telex or telephone
message, statement or other document or conversation believed by it to be
genuine and correct and to have been signed, sent or made by the proper Person
or Persons, and upon advice and statements of legal counsel (including counsel
to the Borrower), independent accountants and other experts selected by the
Agent. The Agent shall be fully justified in failing or refusing to take any
action under this Agreement or any other Loan Document unless it shall first
receive such advice or concurrence of the Required Lenders as it deems
appropriate and, if it so requests, it shall first be indemnified to its
satisfaction by the Lenders against any and all liability and expense which may
be incurred by it by reason of taking or continuing to take any such action.
The Agent shall in all cases be fully protected in acting, or in refraining from
acting, under this Agreement or any other Loan Document in accordance with a
request or consent of the Required Lenders and such request and any action taken
or failure to act pursuant thereto shall be binding upon all of the Lenders.

          (b) For purposes of determining compliance with the conditions
specified in Section 13, each Lender that has executed this Agreement shall be
deemed to have consented to, approved or accepted or to be satisfied with, each
document or other matter either sent by the Agent to such Lender for consent,
approval, acceptance or satisfaction, or required thereunder to be consented to
or approved by or acceptable or satisfactory to the Lender.

     SECTION 15.5  Notice of Default.  The Agent shall not be deemed to have
                   -----------------                                        
knowledge or notice of the occurrence of any Default or Event of Default, except
with respect to defaults in the payment of principal, interest and fees required
to be paid to the Agent for the account of the Lenders, unless the Agent shall
have received written notice from a Lender or the Borrower referring to this
Agreement, describing such Default or Event of Default and stating that such
notice is a "notice of default".  The Agent will notify the Lenders of its
receipt of any such notice.  The Agent shall take such action with respect to
such Default or Event of Default as may be requested by the Required Lenders in
accordance with Section 14.2; provided, however, that unless and until the Agent
                              --------  -------                                 
has received any such request, the Agent may (but shall not be obligated to)
take such action, or refrain from taking such action, with respect to such
Default or Event of Default as it shall deem advisable or in the best interest
of the Lenders.

     SECTION 15.6  Credit Decision.  Each Lender acknowledges that none of the
                   ---------------                                            
Agent-Related Persons has made any representation or warranty to it, and that no
act by the Agent hereinafter taken, including any review of the affairs of any
or all of the Credit Parties, shall be deemed to constitute any representation
or 

                                      -72-
<PAGE>
 
warranty by any Agent-Related Person to any Lender.  Each Lender represents
to the Agent that it has, independently and without reliance upon any Agent-
Related Person and based on such documents and information as it has deemed
appropriate, made its own appraisal of and investigation into the business,
prospects, operations, property, financial and other condition and credit
worthiness of any or all of the Credit Parties, and all applicable bank
regulatory laws relating to the transactions contemplated hereby, and made its
own decision to enter into this Agreement and to extend credit to any or all of
the Credit Parties hereunder.  Each Lender also represents that it will,
independently and without reliance upon any Agent-Related Person and based on
such documents and information as it shall deem appropriate at the time,
continue to make its own credit analysis, appraisals and decisions in taking or
not taking action under this Agreement and the other Loan Documents, and to make
such investigations as it deems necessary to inform itself as to the business,
prospects, operations, property, financial and other condition and credit
worthiness of any or all of the Credit Parties.  Except for notices, reports and
other documents expressly herein required to be furnished to the Lenders by the
Agent, the Agent shall not have any duty or responsibility to provide any Lender
with any credit or other information concerning the business, prospects,
operations, property, financial and other condition or credit worthiness of any
or all of the Credit Parties which may come into the possession of the Agent-
Related Persons.

     SECTION 15.7  Indemnification of Agent.  Whether or not the transactions
                   ------------------------                                  
contemplated hereby are consummated, the Lenders shall indemnify upon demand the
Agent-Related Persons (to the extent not reimbursed by or on behalf of the
Borrower and without limiting the obligation of the Borrower to do so), pro
rata, from and against any and all Indemnified Liabilities; provided, however,
                                                            --------  ------- 
that no Lender shall be liable for the payment to the Agent-Related Persons of
any portion of such Indemnified Liabilities resulting solely from such Person's
gross negligence or willful misconduct. Without limitation of the foregoing,
each Lender shall reimburse the Agent upon demand for its ratable share of any
costs or out-of-pocket expenses (including Attorney Costs) incurred by the Agent
in connection with the preparation, execution, delivery, administration,
modification, amendment or enforcement (whether through negotiations, legal
proceedings or otherwise) of, or legal advice in respect of rights or
responsibilities under, this Agreement, any other Loan Document, or any document
contemplated by or referred to herein, to the extent that the Agent is not
reimbursed for such expenses by or on behalf of the Borrower. The undertaking in
this Section shall survive the payment of all Liabilities hereunder and the
resignation or replacement of the Agent.

     SECTION 15.8  Agent in Individual Capacity.  BofA and its Affiliates may
                   ----------------------------                              
make loans to, issue letters of credit for the 

                                      -73-
<PAGE>
 
account of, accept deposits from, acquire equity interests in and generally
engage in any kind of banking, trust, financial advisory, underwriting or other
business with the Borrower and its Subsidiaries and Affiliates as though BofA
were not the Agent hereunder and without notice to or consent of the Lenders.
The Lenders acknowledge that, pursuant to such activities, BofA or its
Affiliates may receive information regarding the Borrower or its Affiliates
(including information that may be subject to confidentiality obligations in
favor of the Borrower or such Affiliates) and acknowledge that the Agent shall
be under no obligation to provide such information to them. With respect to its
Loans, BofA shall have the same rights and powers under this Agreement as any
other Lender and may exercise the same as though it were not the Agent, and the
terms "Lender" and "Lenders" include BofA in its individual capacity.

     SECTION 15.9  Successor Agent.  The Agent may, and at the request of the
                   ---------------                                           
Required Lenders shall, resign as Agent upon 30 days' notice to the Lenders.  If
the Agent resigns under this Agreement, the Required Lenders shall appoint from
among the Lenders a successor agent for the Lenders [which successor agent shall
be approved by the Borrower (such approval not to be unreasonably withheld)].
If no successor agent is appointed prior to the effective date of the
resignation of the Agent, the Agent may appoint, after consulting with the
Lenders and the Borrower, a successor agent from among the Lenders.  Upon the
acceptance of its appointment as successor agent hereunder, such successor agent
shall succeed to all the rights, powers and duties of the retiring Agent and the
term "Agent" shall mean such successor agent and the retiring Agent's
appointment, powers and duties as Agent shall be terminated. After any retiring
Agent's resignation hereunder as Agent, the provisions of this Section 15 and
Sections 17.3 and 17.4 shall inure to its benefit as to any actions taken or
omitted to be taken by it while it was Agent under this Agreement. If no
successor agent has accepted appointment as Agent by the date which is 30 days
following a retiring Agent's notice of resignation, the retiring Agent's
resignation shall nevertheless thereupon become effective and the Lenders shall
perform all of the duties of the Agent hereunder until such time, if any, as the
Required Lenders appoint a successor agent as provided for above.
Notwithstanding the foregoing, however, BofA may not be removed as the Agent at
the request of the Required Lenders unless BofA shall also simultaneously be
replaced as "Issuing Lender" hereunder pursuant to documentation in form and
substance reasonably satisfactory to BofA.

     SECTION 15.10  Withholding Tax.  (a) If any Lender is a "foreign
                    ---------------                                  
corporation, partnership or trust" within the meaning of the Code and such
Lender claims exemption from, or a reduction of, U.S. withholding tax under
Sections 1441 or 1442 of the Code, such Lender agrees with and in favor of the
Agent, to deliver to the Agent:

                                      -74-
<PAGE>
 
               (i)  if such Lender claims an exemption from, or a reduction of,
     withholding tax under a United States tax treaty, two properly completed
     and executed copies of IRS Form 1001 before the payment of any interest or
     fees in the first calendar year and before the payment of any interest or
     fees in each third succeeding calendar year during which interest or fees
     may be paid under this Agreement;

               (ii)  if such Lender claims that interest or fees paid under this
     Agreement is exempt from United States withholding tax because it is
     effectively connected with a United States trade or business of such
     Lender, two properly completed and executed copies of IRS Form 4224 before
     the payment of any interest or fees is due in the first taxable year of
     such Lender and in each succeeding taxable year of such Lender during which
     interest or fees may be paid under this Agreement; and

               (iii) such other form or forms as may be required under the Code
     or other laws of the United States as a condition to exemption from, or
     reduction of, United States withholding tax.

          Such Lender agrees to promptly notify the Agent of any change in
circumstances which would modify or render invalid any claimed exemption or
reduction.

          (b) If any Lender claims exemption from, or reduction of, withholding
tax under a United States tax treaty by providing IRS Form 1001 and such Lender
sells, assigns, grants a participation in, or otherwise transfers all or part of
the Liabilities of the Borrower owing to such Lender, such Lender agrees to
notify the Agent of the percentage amount in which it is no longer the
beneficial owner of Liabilities of the Borrower owing to such Lender. To the
extent of such percentage amount, the Agent will treat such Lender's IRS Form
1001 as no longer valid.

          (c) If any Lender claiming exemption from United States withholding
tax by filing IRS Form 4224 with the Agent sells, assigns, grants a
participation in, or otherwise transfers all or part of the Liabilities of the
Borrower owing to such Lender, such Lender agrees to undertake sole
responsibility for complying with the withholding tax requirements imposed by
Sections 1441 and 1442 of the Code.

          (d) If any Lender is entitled to a reduction in the applicable
withholding tax, the Agent may withhold from any interest payment to such Lender
an amount equivalent to the applicable withholding tax after taking into account
such reduction.  However, if the forms or other documentation required by
subsection (a) of this Section are not delivered to the Agent, then the Agent
may withhold from any interest payment to such 

                                      -75-
<PAGE>
 
Lender not providing such forms or other documentation an amount equivalent to
the applicable withholding tax imposed by Sections 1441 and 1442 of the Code,
without reduction.

          (e) If the IRS or any other governmental authority of the United
States or other jurisdiction asserts a claim that the Agent did not properly
withhold tax from amounts paid to or for the account of any Lender (because the
appropriate form was not delivered or was not properly executed, or because such
Lender failed to notify the Agent of a change in circumstances which rendered
the exemption from, or reduction of, withholding tax ineffective, or for any
other reason) such Lender shall indemnify the Agent fully for all amounts paid,
directly or indirectly, by the Agent as tax or otherwise, including penalties
and interest, and including any taxes imposed by any jurisdiction on the amounts
payable to the Agent under this Section, together with all costs and expenses
(including Attorney Costs).  The obligation of the Lenders under this subsection
shall survive the payment of all Liabilities and the resignation or replacement
of the Agent.


                  SECTION 16.  ASSIGNMENTS AND PARTICIPATIONS

     SECTION 16.1  Assignments.  (a) With the prior written consent of the Agent
                   -----------                                                  
and the Borrower (not to be unreasonably withheld), each Lender shall have the
right at any time to assign, to any Eligible Assignee, all, or any ratable part
of all, of such Lender's rights and obligations under the Loan Documents
including its rights in respect of Loans, Notes, Letters of Credit and LC
Obligations and its obligations in respect of Commitments to make Loans or
participate in Letters of Credit.  Any such assignment shall be pursuant to an
assignment agreement, substantially in the form of Exhibit K (an "Assignment
                                                   ---------                
Agreement"), duly executed by such Lender and the Eligible Assignee, and
acknowledged by the Agent.  Although its failure to do so will not affect any of
the rights or obligations provided for therein or herein, the Borrower agrees to
duly acknowledge any Assignment Agreement executed by any assigning Lender
promptly after its receipt of the same.  No assignment by the Issuing Lender
shall relieve it from its obligations in respect of the Letters of Credit, it
being understood that any assignment by the Issuing Lender as to Letters of
Credit shall be deemed to automatically constitute an assignment by the Issuing
Lender and the purchase by the Eligible Assignee of a participating interest in
such Letters of Credit.

     (b)  Each assignment, if to a Person other than a Lender, shall be in an
amount equal to or in excess of $5,000,000.  In the case of any such assignment,
upon the execution and delivery of such Assignment Agreement by such Lender and
the Borrower to the Agent, the payment by the assignor and/or Eligible Assignee
of a processing and recording fee of $3,000 to the Agent and the 

                                      -76-
<PAGE>
 
making of any payment by the Eligible Assignee required by the assigning Lender,
this Agreement shall be deemed to be amended to the extent, and only to the
extent, necessary to reflect the addition of such Eligible Assignee, and the
Eligible Assignee shall for all purposes be a Lender party hereto and shall
have, to the extent of such assignment, the same rights and obligations as a
Lender hereunder, including the right to approve or disapprove actions which, in
accordance with the terms hereof, require the approval of the Lenders or the
Required Lenders, as the case may be, and the obligations to make Loans and to
participate in Letters of Credit.

     (c)  Upon the consummation of any assignment, the assigning Lender shall be
relieved from its obligations hereunder to the extent of the obligations so
assigned (except, (i) obligations of the Issuing Lender in respect of the
Letters of Credit issued by it, and (ii) to the extent, if any, that the
Borrower, any other Lender or the Agent has rights against such assigning Lender
as a result of any default by such Lender under this Agreement) and appropriate
arrangements shall be made so that, if required, replacement Notes are issued to
such assigning Lender and new Notes or, as appropriate, replacement Notes are
issued to the Eligible Assignee, in each case in principal amounts reflecting
their outstanding Loans as adjusted pursuant to such Assignment Agreement.
Promptly following the consummation of each assignment, the Agent shall furnish
to the Borrower, the Issuing Lender and each Lender revised Schedule 1.1A,
                                                            ------------- 
revised to reflect such assignment.

     (d)  Notwithstanding Sections 16.1(a) and (b), at any time an Event of
                          ----------------     ---                         
Default shall exist, consent of the Borrower shall not be required in connection
with any assignment by a Lender pursuant to Section 16.
                                            ---------- 

     SECTION 16.2  Participations.  Each Lender may grant participations in all
                   --------------                                              
or any part of its Loans, Notes, Letters of Credit and LC Obligations to any
commercial bank, insurance company or other financial institution.  A
participant shall not have any rights under this Agreement or any other document
delivered in connection herewith (the participant's rights against such Lender
in respect of such participation to be those set forth in the agreement executed
by such Lender in favor of the participant relating thereto, which agreement
with respect to such participation shall not restrict such Lender's ability to
make any modification, amendment or waiver to this Agreement without the consent
of the participant except that the consent of such participant may be required
in connection with matters requiring the consent of all of the Lenders under
Section 17.1).  All amounts payable by the Borrower under this Agreement shall
- ------------                                                                  
be determined as if the Lender had not sold such participation.  In the event of
any such sale by a Lender of participating interests to a participant, such
Lender's obligations under this Agreement 

                                      -77-
<PAGE>
 
shall remain unchanged, such Lender shall remain solely responsible for the
performance thereof, such Lender shall remain the holder of any obligation for
all purposes under this Agreement, and the Borrower and the Agent shall continue
to deal solely and directly with such Lender in connection with such Lender's
rights and obligations under this Agreement.

     SECTION 16.3  Disclosure of Information.  The Borrower authorizes each
                   -------------------------                               
Lender to disclose to any participant, assignee or Eligible Assignee (each, a
"Transferee") and any prospective Transferee any and all financial and other
information in such Lender's possession concerning the Borrower and its
Subsidiaries which has been delivered to such Lender by the Borrower in
connection with such Lender's credit evaluation of the Borrower prior to
entering into this Agreement or which has been delivered to such Lender by the
Borrower pursuant to this Agreement; provided that such Lender shall promptly
                                     --------                                
notify the Borrower of such disclosure.

     SECTION 16.4  Foreign Transferees.  If, pursuant to this Section 16, any
                   -------------------                        ----------     
interest in this Agreement or any Loan, Letter of Credit, Note or LC Obligation
is transferred to any Transferee which is organized under the laws of any
jurisdiction other than the United States or any state thereof, the transferor
Lender shall cause such Transferee (other than any participant), and may cause
any participant, concurrently with the effectiveness of such transfer, (a) to
represent to the transferor Lender (for the benefit of the transferor Lender,
the Agent, and the Borrower) that under applicable law and treaties no Taxes
will be required to be withheld by the Agent, the Borrower or the transferor
Lender with respect to any payments to be made to such Transferee in respect of
the Loans, Notes or Letters of Credit, (b) to furnish to the transferor Lender,
the Agent and the Borrower either U.S. Internal Revenue Service Form 4224 or
U.S. Internal Revenue Service Form 1001 (wherein such transfer claims
entitlement to complete exemption from U.S. federal withholding tax on all
interest payments hereunder), and (c) to agree (for the benefit of the
transferor Lender, the Agent and the Borrower) to provide the transferor Lender,
the Agent and the Borrower a new Form 4224 or Form 1001 upon the obsolescence of
any previously delivered form and comparable statements in accordance with
applicable U.S. laws and regulations and amendments duly executed and completed
by such Transferee, and to comply from time to time with all applicable U.S.
laws and regulations with regard to such withholding tax exemption.

                          SECTION 17.  MISCELLANEOUS

     SECTION 17.1  Waivers and Amendments.  The provisions of any of the Loan
                   ----------------------                                    
Documents may from time to time be amended, modified or waived, if such
amendment, modification or waiver is in writing and consented to by the Borrower
and the Required Lenders; provided, that no such amendment, modification or

     action be taken by all Lenders or by the Required Lenders, shall be
     effective without the consent of each Lender;

preservation of the Collateral.

or any Event of Default, the Agent may exercise from time to time any rights and
remedies available to it under the Uniform Commercial Code as in effect from
time to time in New York  or otherwise available to it, including, without
limitation, sale, assignment, or other disposal of the Collateral in exchange
for cash or credit.  If any notification of intended disposition of any of the
Collateral is required by law, such notification, if sent by certified mail,
shall be deemed reasonably and properly given if mailed at least ten (10) days
before such disposition, postage prepaid, addressed to the Pledgor at the
address of the Pledgor shown below, or at any other addresses of the Pledgor
appearing on the records of the Agent.  Any proceeds of

No rights and remedies of the Agent expressed hereunder are intended to be
exclusive of any other right or remedy, but every such right or remedy shall be
cumulative and shall be in addition to all other rights and remedies herein
conferred, or conferred upon the Agent under any other agreement or instrument
relating to any of the Liabilities or security therefor or now or hereafter
existing at law or in equity or by statute. No delay on the part of the Agent in
the exercise of any right or remedy shall operate as a waiver thereof, and no
single or partial exercise by the Agent of any right or remedy shall preclude
other or further exercise thereof or the exercise of any other right or remedy.
No action of the Agent permitted hereunder shall impair or affect the rights of
the Agent in and to the Collateral.

any Event of Default:

          (a)  The Pledgor agrees that in any sale of any of the Collateral the
     Agent is authorized to comply with any limitation or restriction in
     connection with such sale as counsel may advise the Agent is necessary in
     order to avoid any violation of applicable law (including, without
     limitation, compliance with such procedures as may restrict the number of
     prospective bidders and purchasers, require that such prospective bidders
     and purchasers have certain qualifications, and restrict such prospective
     bidders and purchasers to persons who will represent and agree that they
     are purchasing for their own account for investment and not with a view to
     the distribution or resale of such Collateral), or in order to obtain any
     required approval of the sale or of the purchaser by any governmental
     regulatory authority or official, and the Pledgor further agrees that such
     compliance shall not result in such sale being considered or deemed not to
     have been made in a commercially reasonable manner, nor shall the Agent be
     liable nor accountable to the Pledgor for any discount allowed by reason of
     the fact that such Collateral is sold in compliance with any such
     limitation or restriction.

          (b) If the Agent decides to exercise its right to sell all or any of
     the Pledged Shares or other Collateral, upon written request, the Pledgor
     shall furnish or cause to be furnished to the Agent all such information
     available to it as the Agent may reasonably request in order to qualify
     such Pledged Shares or other Collateral as exempt securities, or the sale
     or resale of 
                                     E-11
<PAGE>
 
     such Pledged Shares or other Collateral as exempt transactions, under
     federal and state securities laws. The Pledgor agrees to allow, and to
     cause the Issuer to allow, the Agent and any underwriter access at
     reasonable times and places to the books, records and premises of the
     Pledgor and the Issuer. The Pledgor further agrees to assist, and cause the
     Issuer to assist, the Agent, any underwriter, any agent of any thereof, and
     any counsel, accountant or other expert for any thereof, in inspection,
     evaluation, and any other "due diligence" action of or with respect to any
     such books, records and premises; and the Pledgor further agrees to use its
     reasonable best efforts to cause any independent public accountant for the
     Issuer to furnish a letter to the Agent and underwriters in customary form
     and covering matters of the type customarily covered by letters of
     accountants for issuers to underwriters.

any of its directors, officers, agents or employees shall be liable for any
action taken or omitted to be taken by it hereunder or in connection herewith
including actions taken or omitted to be taken as a result of its negligence,
except for its or their own gross negligence or willful misconduct or for
violation of law as determined by a court of competent jurisdiction or in
connection with litigation between Pledgor and the Agent unless otherwise
determined or agreed to in such litigation. The Pledgor hereby agrees to pay on
demand all reasonable expenses of the Agent (including the fees and out-of-
pocket expenses of counsel to the Agent and of local counsel, if any, who may be
retained by counsel to the Agent) incurred by the Agent in connection with the
enforcement of this Pledge Agreement (including, without limitation, reasonable
costs and expenses incurred by any agent employed by the Agent) and agrees to
indemnify and hold the Agent (and any such agent employed by the Agent) harmless
from and against any and all liabilities, losses, damages, costs and expenses of
any kind (including, without limitation, the reasonable fees and disbursements
of counsel for the Agent) which may be incurred by the Agent (or such agent
employed by the Agent) hereunder or in connection herewith (including without
limitation, any liability arising by reason of the negligence of the Agent),
provided, that the Agent, or such agent employed by the Agent, as the case may

be, shall not have the right to be indemnified hereunder for its own gross
negligence or willful misconduct or for violation of this Pledge Agreement or
law as determined by a court of competent jurisdiction or in connection with

          The Pledgor agrees that its pledge hereunder shall (notwithstanding,
without limitation, that at any time or from time to time all Liabilities may
have been paid in full) terminate only when all Liabilities (including, without
limitation, any extensions or renewals of any thereof), but excluding contingent
liabilities which expressly survive the termination of the Credit Agreement or
the other Related Documents and all interest thereon and all reasonable expenses
(including, without limitation, attorneys' fees and legal expenses) paid or
incurred by the Agent or the holder or the holders of the Notes in endeavoring

Pledgor shall designate, such of the Collateral (if any) as shall not have been
sold or otherwise applied by the Agent pursuant to the terms hereof and shall
still be held by it hereunder, together with appropriate instruments of
reassignment and release. Any such reassignment shall be without recourse upon,

                               W I T N E S E T H:
                               - - - - - - - - - 

          WHEREAS, NOVA Information Systems, Inc., a Georgia corporation (the
"Borrower"), has entered into a Credit Agreement, dated as of October 27, 1997
(as amended or otherwise modified from time to time, the "Credit Agreement")
with the lenders who are or may become party to the Credit Agreement (together
with their respective successors and assigns, the "Lenders"), the Issuing Lender
and the Agent, pursuant to which the Lenders and the Issuing Lender have agreed
to make Loans to and issue or participate in the issuance of Letters of Credit

          WHEREAS, the undersigned will benefit from the making of Loans and the
issuance of the Letters of Credit pursuant to the Credit Agreement and is
willing to guaranty the Liabilities (as defined below) as hereinafter set forth;

          NOW, THEREFORE, for good and valuable consideration, the receipt and
sufficiency of which are hereby acknowledged, the undersigned hereby, as primary
obligor and not merely as surety, guarantees the full and prompt payment when
due, whether at stated maturity, by required prepayment, declaration, demand,
acceleration or otherwise (including amounts that would become due but for the
operation of the automatic stay under section 362(a) of the Bankruptcy Code (11
U.S.C. (S) 362(a)), and at all times thereafter, of all obligations (monetary or
otherwise) of the Borrower to each of the Lenders, the Issuing Lender and the
Agent, howsoever created, arising or evidenced, whether direct or indirect,
absolute or contingent, now or hereafter existing, or due or to become due,
including (without limitation) all obligations which arise out of or in
connection with the Credit Agreement or any Related Document, in each case as
the same may be amended, modified, extended or renewed from time to time (all
such obligations being herein collectively called the "Liabilities"), and the
undersigned further agrees to pay all reasonable expenses (including reasonable
                                      F-1
<PAGE>
 
attorneys' fees and legal expenses) paid or incurred by the Lenders, the Issuing
Lender and the Agent in endeavoring to collect the Liabilities, or any part
thereof, and in enforcing this Guaranty; provided, however, that the liability
                                         --------  -------  
of the undersigned hereunder shall be limited to the maximum amount of the
Liabilities which the undersigned may guaranty without violating any fraudulent
conveyance or fraudulent transfer law (plus all costs and expenses paid or
incurred by the Agent, the Lenders or the Issuing Lender in enforcing this
Guaranty against the undersigned).

          1.  The undersigned agrees that, in the event of the occurrence of an
Event of Default pursuant to Section 14.1.3 of the Credit Agreement, and if any
such event shall occur at a time when any of the Liabilities may not then be due
and payable, the undersigned will pay to the Agent for the benefit of the
Lenders and the Issuing Lender forthwith the full amount which would be payable
hereunder by the undersigned if all Liabilities were then due and payable.

          2.  To secure all obligations of the undersigned hereunder, the Agent
for the benefit of the Lenders and the Issuing Lender shall have a lien upon and
security interest in (and may, without demand or notice of any kind, at any time
and from time to time when any amount shall be due and payable by the
undersigned hereunder, appropriate and apply toward the payment of such amount,
in such order of application as the Agent may elect) any and all balances,
credits, deposits (general or specific, time or demand, provisional or final),
accounts or moneys of or in the name of the undersigned now or hereafter
maintained with the Agent, any Lender or the Issuing Lender and any and all
property of every kind or description of or in the name of the undersigned now
or hereafter, for any reason or purpose whatsoever, in the possession or control
of, or in transit to, the Agent, any Lender or the Issuing Lender or any agent
or bailee for the Agent, any Lender or the Issuing Lender.

          3.  This Guaranty shall in all respects be a continuing, absolute and
unconditional guaranty, and shall remain in full force and effect
(notwithstanding, without limitation, the dissolution of the undersigned or that
at any time or from time to time all Liabilities may have been paid in full),
subject to discontinuance as to the undersigned only upon actual receipt by the
Agent of written notice from the undersigned, or any person duly authorized and
acting on behalf of the undersigned, of the discontinuance hereof as to the
undersigned; provided, however, that no such notice of discontinuance shall
             --------  -------                                             
affect or impair any of the agreements and obligations of the undersigned
hereunder with respect to any and all Liabilities existing prior to the time of
actual receipt of such notice by the Agent, any and all Liabilities 

                                      F-2
<PAGE>
 
created or acquired thereafter pursuant to any previous commitments created or
acquired thereafter pursuant to any previous commitments made by the Agent, the
Lenders or the Issuing Lender, any and all extensions or renewals of any of the
foregoing, any and all interest on any of the foregoing, and any and all
expenses paid or incurred by the Agent, any Lender or the Issuing Lender in
endeavoring to collect any of the foregoing and in enforcing this Guaranty
against the undersigned; and all of the agreements and obligations of the
undersigned under this Guaranty shall, notwithstanding any such notice of
discontinuance, remain fully in effect until all such Liabilities (other than
Liabilities which expressly survive the payment in full of the Loans and LC
Obligations and the termination of the Commitments but including any extensions
or renewals of any thereof) and all such interest and expenses shall have been
paid in full and all Commitments have terminated.

          4.  The undersigned further agrees that, if at any time all or any
part of any payment theretofore applied by the Agent to any of the Liabilities
is or must be rescinded or returned by the Agent, the Lenders or the Issuing
Lender for any reason whatsoever (including, without limitation, the insolvency,
bankruptcy or reorganization of the Borrower or the undersigned), such
Liabilities shall, for the purposes of this Guaranty, to the extent that such
payment is or must be rescinded or returned, be deemed to have continued in
existence, notwithstanding such application by the Agent, and this Guaranty
shall continue to be effective or be reinstated, as the case may be, as to such
Liabilities, all as though such application by the Agent had not been made.

          5.  The undersigned agrees that the Agent, any Lender or the Issuing
Lender may, from time to time, whether before or after any discontinuance of
this Guaranty, at its sole discretion and without notice to the undersigned,
take any or all of the following actions without affecting the obligations of
the undersigned hereunder:

          (a)  Retain or obtain a security interest in any property to secure
     any of the Liabilities or any obligation hereunder;

          (b)  Retain or obtain the primary or secondary obligation of any
     obligor or obligors, in addition to the undersigned with respect to any of
     the Liabilities;

          (c)  Extend or renew for one or more periods (whether or not longer
     than the original period), or alter or exchange, any of the Liabilities, or
     release or compromise any obligation of the 

                                      F-3
<PAGE>
 
     undersigned hereunder or any obligation of any nature of the undersigned
     with respect to any of the Liabilities;

          (d)  Release its security interest in, or surrender, release or permit
     any substitution or exchange for, all or any part of any property securing
     any of the Liabilities or any obligation hereunder, or extend or renew for
     one or more periods (whether or not longer than the original period) or
     release, compromise, alter or exchange any obligations of any nature of any
     obligor with respect to any such property; and

          (e)  Resort to the undersigned for payment of any of the Liabilities,
     whether or not the Agent (i) shall have resorted to any property securing
     any of the Liabilities or any obligation hereunder or (ii) shall have
     proceeded against any other obligor primarily or secondarily obligated with
     respect to any of the Liabilities (all of the actions referred to in
     preceding clauses (i) and (ii) being hereby expressly waived by the
               -----------     ----                                     
     undersigned).

          6.  Any amounts received by the Agent from whatsoever source on
account of the Liabilities may be applied in whole or in part by the Agent
against, all or any part of the Liabilities in such order as the Agent shall
elect.

          7.  No payment made by or for the account of the undersigned pursuant
to this Guaranty shall entitle the undersigned by subrogation or otherwise to
any payment by the Borrower or from or out of any property of the Borrower and
the undersigned shall not exercise any right or remedy against the Borrower or
any property of the Borrower by reason of any performance by the undersigned of
this Guaranty.  The undersigned expressly waives, to the fullest extent
permitted by law, all claims or rights of the undersigned against the Borrower,
arising out of any payment by the undersigned under this Guaranty, whether
arising by way of any subrogation, contribution, reimbursement or otherwise and
agrees that, to the extent that any such rights may not be waived under
applicable law, it will contribute such rights to the Borrower as a capital
contribution concurrently with the arising of such rights.

          8.  The undersigned hereby expressly waives:

                                      F-4
<PAGE>
 
          (a)  Notice of the acceptance by the Agent, any Lender or the Issuing
     Lender of this Guaranty;

          (b)  Notice of the existence or creation or non-payment of all or any
     of the Liabilities;

          (c)  Presentment, demand, notice of dishonor, protest and all other
     notices whatsoever; and

          (d)  All diligence in collection or protection of or realization upon
     the Liabilities or any thereof, any obligation hereunder, or any security
     for or guaranty of any of the foregoing.

          9.  The creation or existence from time to time of additional
Liabilities to the Agent, the Lenders or the Issuing Lender or any of them is
hereby authorized, without notice to the undersigned, and shall in no way affect
or impair the rights of the Agent, the Lenders or the Issuing Lender or the
obligations of the undersigned under this Guaranty of such additional
Liabilities.

          10.  Subject to the provisions of Section 16 of the Credit Agreement,
the Agent, any Lender and the Issuing Lender may, from time to time, whether
before or after any discontinuance of this Guaranty, without notice to the
undersigned, assign or transfer any or all of the Liabilities or any interest
therein; and, notwithstanding any such assignment or transfer or any subsequent
assignment or transfer thereof, such Liabilities shall be and remain Liabilities
for the purposes of this Guaranty, and each and every immediate and successive
assignee or transferee of any of the Liabilities or of any interest therein
shall, to the extent of the interest of such assignee or transferee in the
Liabilities, be entitled to the benefits of this Guaranty to the same extent as
if such assignee or transferee were a Lender; provided, however, that unless
                                              --------  -------             
such Lender shall otherwise consent in writing, the Lender shall have an
unimpaired right prior and superior to that of any such assignee or transferee,
to enforce this Guaranty, for its benefit, as to those of the Liabilities which
it has not assigned or transferred.

          11.  The undersigned hereby warrants to the Agent, the Lenders and the
Issuing Lender that the undersigned now has and will continue to have
independent means of obtaining information concerning the affairs, financial
condition and business of the Borrower.  The Agent, the Lenders and the Issuing
Lender shall not have any duty or responsibility to provide the undersigned with
any credit or other information concerning the affairs, financial condition or
business of the Borrower which may come into the Agent's, any such Lender's or
the Issuing Lender's possession.

                                      F-5

          12.  The undersigned hereby warrants and agrees that:

          (a)  The undersigned is a corporation duly existing and in good
     standing under the laws of the State of Georgia and the undersigned is duly
     qualified and in good standing and authorized to do business in each

          (b)  The undersigned has full power and authority to execute and
     deliver this Guaranty;

          (c)  The execution, delivery and performance by the undersigned of

     contravene or conflict with any provision of law or of the organizational
     documents of the undersigned or of any agreement binding upon the
     undersigned;

          (d)  This Guaranty is the legal, valid and binding obligation of the
     undersigned enforceable against the undersigned in accordance with its
     terms, except as enforceability may be limited by bankruptcy or other laws
     relating to or affecting creditors' rights generally or by equitable
     principles; and

          (e)  This Guaranty will directly or indirectly benefit the
     undersigned.

          (f)  The representations and warranties set forth in Section 9 which
                                                               ---------      
     relate to the undersigned are true and correct in all material respects.

          13.  No delay on the part of the Agent, any Lender or the Issuing
Lender in the exercise of any right or remedy shall operate as a waiver thereof,
and no single or partial exercise by the Agent, any Lender or the Issuing Lender
of any right or remedy shall preclude other or further exercise thereof or the
exercise of any other right or remedy; nor shall any modification or waiver of
any of the provisions of this Guaranty be binding upon the Agent, the Lenders
and the Issuing Lender except as expressly set forth in a writing duly signed
and delivered on behalf of the Agent for the benefit of the Lenders and the
Issuing Lender.  No action of the Agent, any Lender or the Issuing Lender
permitted hereunder shall

<PAGE>
 
in any way affect or impair the rights of the Agent, any Lender or the Issuing
Lender or the obligations of the undersigned under this Guaranty. For the
purposes of this Guaranty, Liabilities shall include all obligations of the
Borrower to the Agent, any Lender or the Issuing Lender, notwithstanding any
right or power of the Borrower or anyone else to assert any claim or defense as

or defense shall affect or impair the obligations of the undersigned hereunder.
The undersigned agrees that the obligations of the undersigned under this
Guaranty shall be absolute and unconditional irrespective of any circumstance
whatsoever which might constitute a legal or equitable discharge or defense of

conditions to the effectiveness of this Guaranty.

delivered to the Agent and (b) the Agent has been authorized to enforce this
Guaranty on behalf of itself and each of the Lenders and the Issuing Lender.

GUARANTY SHALL BE PROHIBITED BY OR INVALID UNDER SUCH LAW, SUCH PROVISION SHALL
BE INEFFECTIVE TO THE EXTENT OF SUCH PROHIBITION OR INVALIDITY, WITHOUT

                          FORM OF SUBSIDIARY GUARANTY


          THIS GUARANTY, dated as of October 27, 1997 (herein called this
"Guaranty"), is executed by the undersigned in favor of Bank of America National
Trust and Savings Association, as agent for the Lenders and the Issuing Lender
under the Credit Agreement referred to below (in such capacity, together with
any successor thereto in such capacity, called the "Agent").  Unless otherwise
defined herein, capitalized terms used herein have the meanings provided in said
Credit Agreement.

                               W I T N E S E T H:
                               - - - - - - - - - 

          WHEREAS, NOVA Information Systems, Inc., a Georgia corporation (the
"Borrower"), has entered into a Credit Agreement, dated as of October 27, 1997
(as amended or otherwise modified from time to time, the "Credit Agreement")
with the lenders who are or may become party to the Credit Agreement (together
with their respective successors and assigns, the "Lenders"), the Issuing Lender
and the Agent, pursuant to which the Lenders and the Issuing Lender have agreed
to make Loans to and issue or participate in the issuance of Letters of Credit
for the account of the Borrower; and

          WHEREAS, the undersigned will benefit from the making of Loans and the
issuance of the Letters of Credit pursuant to the Credit Agreement and is
willing to guaranty the Liabilities (as defined below) as hereinafter set forth;

          NOW, THEREFORE, for good and valuable consideration, the receipt and
sufficiency of which are hereby acknowledged, the undersigned hereby, as primary
obligor and not merely as surety, guarantees the full and prompt payment when
due, whether at stated maturity, by required prepayment, declaration, demand,
acceleration or otherwise (including amounts that would become due but for the
operation of the automatic stay under section 362(a) of the Bankruptcy Code (11
U.S.C. (S) 362(a)), and at all times thereafter, of all obligations (monetary or
otherwise) of the Borrower to each of the Lenders, the Issuing Lender and the
Agent, howsoever created, arising or evidenced, whether direct or indirect,
absolute or contingent, now or hereafter existing, or due or to become due,
including (without limitation) all obligations which arise out of or in
connection with the Credit Agreement or any Related Document, in each case as
the same may be amended, modified, extended or renewed from time to time (all
such obligations being herein collectively called the "Liabilities"), and the
undersigned further agrees to pay all reasonable expenses (including reasonable
                                      G-1
<PAGE>
 
attorneys' fees and legal expenses) paid or incurred by the Lenders, the Issuing
Lender and the Agent in endeavoring to collect the Liabilities, or any part
thereof, and in enforcing this Guaranty; provided, however, that the liability
                                         --------  -------
of the undersigned hereunder shall be limited to the maximum amount of the
Liabilities which the undersigned may guaranty without violating any fraudulent
conveyance or fraudulent transfer law (plus all costs and expenses paid or
incurred by the Agent, the Lenders or the Issuing Lender in enforcing this
Guaranty against the undersigned).

          1.  The undersigned agrees that, in the event of the occurrence of an
Event of Default pursuant to Section 14.1.3 of the Credit Agreement, and if any
such event shall occur at a time when any of the Liabilities may not then be due
and payable, the undersigned will pay to the Agent for the benefit of the
Lenders and the Issuing Lender forthwith the full amount which would be payable
hereunder by the undersigned if all Liabilities were then due and payable.

          2.  To secure all obligations of the undersigned hereunder, the Agent
for the benefit of the Lenders and the Issuing Lender shall have a lien upon and
security interest in (and may, without demand or notice of any kind, at any time
and from time to time when any amount shall be due and payable by the
undersigned hereunder, appropriate and apply toward the payment of such amount,
in such order of application as the Agent may elect) any and all balances,
credits, deposits (general or specific, time or demand, provisional or final),
accounts or moneys of or in the name of the undersigned now or hereafter
maintained with the Agent, any Lender or the Issuing Lender and any and all
property of every kind or description of or in the name of the undersigned now
or hereafter, for any reason or purpose whatsoever, in the possession or control
of, or in transit to, the Agent, any Lender or the Issuing Lender or any agent
or bailee for the Agent, any Lender or the Issuing Lender.

          3.  This Guaranty shall in all respects be a continuing, absolute and
unconditional guaranty, and shall remain in full force and effect
(notwithstanding, without limitation, the dissolution of the undersigned or that
at any time or from time to time all Liabilities may have been paid in full),
subject to discontinuance as to the undersigned only upon actual receipt by the
Agent of written notice from the undersigned, or any person duly authorized and
acting on behalf of the undersigned, of the discontinuance hereof as to the
undersigned; provided, however, that no such notice of discontinuance shall
             --------  -------                                             
affect or impair any of the agreements and obligations of the undersigned
hereunder with respect to any and all Liabilities existing prior to the time of
actual receipt of such notice by the Agent, any and all Liabilities created or
acquired thereafter pursuant to any previous commitments 

                                      G-2
<PAGE>
 
made by the Agent, the Lenders or the Issuing Lender, any and all extensions or
renewals of any of the foregoing, any and all interest on any of the foregoing,
and any and all expenses paid or incurred by the Agent, any Lender or the
Issuing Lender in endeavoring to collect any of the foregoing and in enforcing
this Guaranty against the undersigned; and all of the agreements and obligations
of the undersigned under this Guaranty shall, notwithstanding any such notice of
discontinuance, remain fully in effect until all such Liabilities (other than
Liabilities which expressly survive the payment in full of the Loans and LC
Obligations and the termination of the Commitments but including any extensions
or renewals of any thereof) and all such interest and expenses shall have been
paid in full and all Commitments have terminated.

          4.  The undersigned further agrees that, if at any time all or any
part of any payment theretofore applied by the Agent to any of the Liabilities
is or must be rescinded or returned by the Agent, the Lenders or the Issuing
Lender for any reason whatsoever (including, without limitation, the insolvency,
bankruptcy or reorganization of the Borrower or the undersigned), such
Liabilities shall, for the purposes of this Guaranty, to the extent that such
payment is or must be rescinded or returned, be deemed to have continued in
existence, notwithstanding such application by the Agent, and this Guaranty
shall continue to be effective or be reinstated, as the case may be, as to such
Liabilities, all as though such application by the Agent had not been made.

          5.  The undersigned agrees that the Agent, any Lender or the Issuing
Lender may, from time to time, whether before or after any discontinuance of
this Guaranty, at its sole discretion and without notice to the undersigned,
take any or all of the following actions without affecting the obligations of
the undersigned hereunder:

          (a)  Retain or obtain a security interest in any property to secure
     any of the Liabilities or any obligation hereunder;

          (b)  Retain or obtain the primary or secondary obligation of any
     obligor or obligors, in addition to the undersigned with respect to any of
     the Liabilities;

          (c)  Extend or renew for one or more periods (whether or not longer
     than the original period), or alter or exchange, any of the Liabilities, or
     release or compromise any obligation of the undersigned hereunder or any
     obligation of any 

                                      G-3
<PAGE>
 
     nature of the undersigned with respect to any of the Liabilities;

          (d)  Release its security interest in, or surrender, release or permit
     any substitution or exchange for, all or any part of any property securing
     any of the Liabilities or any obligation hereunder, or extend or renew for
     one or more periods (whether or not longer than the original period) or
     release, compromise, alter or exchange any obligations of any nature of any
     obligor with respect to any such property; and

          (e)  Resort to the undersigned for payment of any of the Liabilities,
     whether or not the Agent (i) shall have resorted to any property securing
     any of the Liabilities or any obligation hereunder or (ii) shall have
     proceeded against any other obligor primarily or secondarily obligated with
     respect to any of the Liabilities (all of the actions referred to in
     preceding clauses (i) and (ii) being hereby expressly waived by the
               -----------     ----                                     
     undersigned).

          6.  Any amounts received by the Agent from whatsoever source on
account of the Liabilities may be applied in whole or in part by the Agent
against, all or any part of the Liabilities in such order as the Agent shall
elect.

          7.  No payment made by or for the account of the undersigned pursuant
to this Guaranty shall entitle the undersigned by subrogation or otherwise to
any payment by the Borrower or from or out of any property of the Borrower and
the undersigned shall not exercise any right or remedy against the Borrower or
any property of the Borrower by reason of any performance by the undersigned of
this Guaranty.  The undersigned expressly waives, to the fullest extent
permitted by law, all claims or rights of the undersigned against the Borrower,
arising out of any payment by the undersigned under this Guaranty, whether
arising by way of any subrogation, contribution, reimbursement or otherwise and
agrees that, to the extent that any such rights may not be waived under
applicable law, it will contribute such rights to the Borrower as a capital
contribution concurrently with the arising of such rights.

          8.  The undersigned hereby expressly waives:

          (a)  Notice of the acceptance by the Agent, any Lender or the Issuing
     Lender of this Guaranty;

                                      G-4
<PAGE>
 
          (b)  Notice of the existence or creation or non-payment of all or any
     of the Liabilities;

          (c)  Presentment, demand, notice of dishonor, protest and all other
     notices whatsoever; and

          (d)  All diligence in collection or protection of or realization upon
     the Liabilities or any thereof, any obligation hereunder, or any security
     for or guaranty of any of the foregoing.

          9.   The creation or existence from time to time of additional
Liabilities to the Agent, the Lenders or the Issuing Lender or any of them is
hereby authorized, without notice to the undersigned, and shall in no way affect
or impair the rights of the Agent, the Lenders or the Issuing Lender or the
obligations of the undersigned under this Guaranty of such additional
Liabilities.

          10.  Subject to the provisions of Section 16 of the Credit Agreement,
the Agent, any Lender and the Issuing Lender may, from time to time, whether
before or after any discontinuance of this Guaranty, without notice to the
undersigned, assign or transfer any or all of the Liabilities or any interest
therein; and, notwithstanding any such assignment or transfer or any subsequent
assignment or transfer thereof, such Liabilities shall be and remain Liabilities
for the purposes of this Guaranty, and each and every immediate and successive
assignee or transferee of any of the Liabilities or of any interest therein
shall, to the extent of the interest of such assignee or transferee in the
Liabilities, be entitled to the benefits of this Guaranty to the same extent as
if such assignee or transferee were a Lender; provided, however, that unless
                                              --------  -------             
such Lender shall otherwise consent in writing, the Lender shall have an
unimpaired right prior and superior to that of any such assignee or transferee,
to enforce this Guaranty, for its benefit, as to those of the Liabilities which
it has not assigned or transferred.

          11.  The undersigned hereby warrants to the Agent, the Lenders and the
Issuing Lender that the undersigned now has and will continue to have
independent means of obtaining information concerning the affairs, financial
condition and business of the Borrower.  The Agent, the Lenders and the Issuing
Lender shall not have any duty or responsibility to provide the undersigned with
any credit or other information concerning the affairs, financial condition or
business of the Borrower which may come into the Agent's, any such Lender's or
the Issuing Lender's possession.

          12.  The undersigned hereby warrants and agrees that:

     standing under the laws of the State of Georgia and the undersigned is duly
     qualified and in good standing and authorized to do business in each

          (b)  The undersigned has full power and authority to execute and
     deliver this Guaranty;

          (c)  The execution, delivery and performance by the undersigned of
     this Guaranty are within the undersigned's powers, have been duly
     authorized by all necessary action, have received all necessary
     governmental approval (if any shall be required), and do not and will not
     contravene or conflict with any provision of law or of the organizational
     documents of the undersigned or of any agreement binding upon the
     undersigned;

          (d)  This Guaranty is the legal, valid and binding obligation of the
     undersigned enforceable against the undersigned in accordance with its

     relating to or affecting creditors' rights generally or by equitable
     principles; and

          (e)  This Guaranty will directly or indirectly benefit the
     undersigned.

          13.  No delay on the part of the Agent, any Lender or the Issuing
Lender in the exercise of any right or remedy shall operate as a waiver thereof,
and no single or partial exercise by the Agent, any Lender or the Issuing Lender
of any right or remedy shall preclude other or further exercise thereof or the
exercise of any other right or remedy; nor shall any modification or waiver of
any of the provisions of this Guaranty be binding upon the Agent, the Lenders
and the Issuing Lender except as expressly set forth in a writing duly signed
and delivered on behalf of the Agent for the benefit of the Lenders and the
Issuing Lender.  No action of the Agent, any Lender or the Issuing Lender
permitted hereunder shall in any way affect or impair the rights of the Agent,
any Lender or the Issuing Lender or the obligations of the undersigned under
this Guaranty.  For the purposes of this Guaranty, Liabilities shall include all
obligations of the Borrower to the Agent, any Lender or the Issuing Lender,
notwithstanding any right or power of the Borrower or anyone else to assert any
claim or defense as to the 
                                      G-6
<PAGE>
 
invalidity or unenforceability of any such obligation, and no such claim or
defense shall affect or impair the obligations of the undersigned hereunder. The
undersigned agrees that the obligations of the undersigned under this Guaranty
shall be absolute and unconditional irrespective of any circumstance whatsoever
which might constitute a legal or equitable discharge or defense of the
undersigned. The undersigned hereby acknowledges that there are no conditions to
the effectiveness of this Guaranty.

          14.  Pursuant to the Credit Agreement, (a) this Guaranty has been
delivered to the Agent and (b) the Agent has been authorized to enforce this
Guaranty on behalf of itself and each of the Lenders and the Issuing Lender.

          15.  This Guaranty shall be binding upon the undersigned, and upon any

BE CONSTRUED IN ACCORDANCE WITH AND GOVERNED BY THE INTERNAL LAWS OF THE STATE
OF NEW YORK  WITHOUT GIVING EFFECT TO ITS PRINCIPLES OF CHOICE OF LAW.  WHEREVER
POSSIBLE EACH PROVISION OF THIS GUARANTY SHALL BE INTERPRETED IN SUCH MANNER AS

June 10, 1997

Mr. Rick Pylant
Vice President
Network Services Division
Mellon Bank, N.A.
1070 One Mellon Bank Center
Pittsburgh, PA 15258-0001

Dear Rick:

     This letter will constitute an amendment to the Agreement ("Agreement")
dated June 3, 1992 among NOVA Information Systems, Inc. ("NOVA"), Inter-Banc,
Inc. and Mellon Bank, N.A. ("Mellon").

The Agreement is hereby amended as follows:

     1. Fees.  In order to induce NOVA to continue presenting transactions to
        -----
Mellon under the Agreement, Mellon has agreed to lower its fees.  The fees under
the Agreement are set forth on a Fee Letter dated June 3, 1992 ("Fee Letter"),
which was amended by a Fee Letter amendment dated December 10, 1992 ("Fee Letter
Amendment").  Therefore, the Fee Letter as amended by Schedule 1 of the Fee
Letter Amendment ("Schedule 1") is hereby amended as set forth on Exhibit A,
Fees.  Exhibit A will replace and supersede the Fee Letter and Schedule 1.
Exhibit A is effective as of March 1, 1997.  With respect to all services to be
provided by Mellon "at cost," Mellon will provide to NOVA adequate documentation
regarding Mellon's actual costs.

     2.  Billing Disputes.  Section 6 of the Agreement is amended by adding the
         -----------------
following new Subsection (d):

    (d) The parties will work diligently to resolve billing disputes within 30
    days of the date of Mellon's invoice. Neither party may invoice or collect
    from the other party any charges attributable to transactions or events
    occurring more than 30 days prior to the date such party is first notified
    in writing of a misbilled item.

     3.  Rights of Termination. Section 14(a)(iv) shall be deleted in it
         --------------------- 
entirety and shall be replaced with the addition of Sections 15(f) and 15(g)
to Section 15 Term; Termination.
   ----------------------------

    Section 15(f). This Agreement may be terminated by Mellon upon 60 days prior
    written notice in the event NOVA experiences a "Change of Control". NOVA
    must provide Mellon with written notification of "Change of Control" within
    thirty (30) days of the occurrence of any of the following events.

    "Change of Control" shall mean (a) any Person or group of Persons within (as
    used in Sections 13 and 14 of the Securities Exchange Act of 1934 (the
    "Exchange Act"), and the rules and regulations thereunder) shall have become
    the beneficial owner (as defined in Rules 13d-3 and 13d-5 promulgated by the
    Securities and Exchange Commission under the Exchange Act) of 20% or more of
    NOVA's outstanding voting stock, or (b) a change in the board of directors
    of NOVA shall have occurred which results in a majority of directors not
    being "Continuing Directors". For purposes of this provision, "Continuing
    Directors" are members of NOVA's board of directors who (a) were directors
    as of the date of this Amendment, (b) have been directors for at least two
    years or (c) were nominated or elected with the affirmative vote of a
    majority of the Continuing Directors on the board.

    Section 15(g). This Agreement may be terminated by NOVA upon 60 days prior
    written notice in the event of the current shareholders of Mellon (or its
    parent corporation) shall cease to hold at least 20% of all the issued and
    outstanding shares of capital stock of Mellon (or its parent corporation),
    or there shall occur any sale, acquisition, merger, exchange or similar
    transaction involving the assets of the Network Services Division of Mellon
    to where they are owned or controlled by a party other than Mellon.

     4. Agreement. All provisions of the Agreement not mentioned above will
        ----------
remain in full force and effect. The Agreement consists of: A) the Consent
Letter and the Fee Letter, both dated June 3, 1992, and B) all amendments to the
Agreement (except Amendment No. 2 dated April 28, 1994 which has been superseded
by a separate agreement between the parties), including the following:

      i)   Amendment No. 1 dated December 9, 1992.
     ii)   Amendment to the Fee Letter dated December 10, 1992.
    iii)   Letter Agreement dated November 2, 1994.

     5. Notice of Termination. NOVA also hereby nullifies the notice of
        ----------------------
termination of the Agreement to you from Edward Grzedzinski dated January 24,
1997. Further, the parties agree that, notwithstanding anything contained in
the Agreement to the contrary, the current term of the Agreement shall expire
on June 30, 1998. Provided, however, the Agreement shall automatically renew
for additional successive one-year terms unless either party provides notice of
intent not to renew at least 120 days prior to the expiration of the then
current term. If Mellon and NOVA agree to enter into an agreement regarding
terminal driving services, the term of the Agreement may be negotiated by the
parties.

If this letter accurately reflects our agreement regarding the amendment to the
Agreement, please sign the enclosed copy in the space provided and return it to
us by June 16, 1997.

     We look forward to working with you and to continuing a mutually beneficial
relationship in the future.

                                     Very truly yours,

                                     /s/ Pamela A. Joseph

                                     Pamela A. Joseph
                                     Senior Vice President and
                                     Chief Information Officer



Accepted and agreed to this 11th day of June, 1997.

          ---------                                                 

                               R E C I T A L S:
                               --------------- 

     WHEREAS, KeyBank seeks to form an alliance with a company providing Bank
Card Processing services to maximize efficiencies and create economies of scale;

     WHEREAS, NOVA is a company engaged in the business of providing Bank Card
Processing services, including the business of providing Bank Card Processing
services to commercial establishments that accept Credit Card and Debit Card
products;

     WHEREAS, KeyBank Sub and NOVA desire to become members of a limited
liability company to provide Bank Card Processing services for Merchants,
including New Merchants;

     NOW, THEREFORE, in consideration of these premises and the mutual covenants
set forth herein, the parties hereby agree as follows:


                                   ARTICLE I

                    REPRESENTATIONS AND WARRANTIES OF NOVA

     NOVA Corp and NOVA jointly and severally represent and warrant to KeyBank
as follows:

     1.01  Each of NOVA Corp and NOVA is a corporation duly organized, validly
existing and in good standing under the laws of the State of Georgia and has due
authority to conduct business in all states where it conducts business, except
where the failure to have such authority has not and will not have a Material
Adverse Effect.

     1.02  The execution and delivery of this Agreement and the consummation of
the transactions herein contemplated do not conflict in any material respect
with, or constitute a material breach or Default under, the organizational
documents of NOVA Corp or NOVA or under the terms and conditions of any Contract
to which NOVA Corp or NOVA is a party.
<PAGE>
 
     1.03  The NOVA Corp Financial Statements fairly present the financial
condition of NOVA Corp and its subsidiaries as of their respective dates, and
the results of operations of NOVA Corp and its subsidiaries for the periods
indicated, in accordance with GAAP applied on a consistent basis throughout the

disclosed by NOVA Corp in financial statements prepared in accordance with GAAP
applied on a basis consistent throughout the periods involved other than (i)

Financial Statements, and (iii) Liabilities, ordinary in nature and amount,
incurred since September 30, 1997 in the ordinary course of business.  To the

1997, there has been no Material Adverse Effect on NOVA Corp or any of its

amended, as the case may be, and (ii) did not at the time they were filed
contain any untrue statement of a material fact or omit to state a material fact
required to be stated therein or necessary in order to make the statements
therein, in the light of the circumstances under which they were made, not
misleading.

     1.05  Neither NOVA Corp nor NOVA has received notice from any Regulatory
Authority indicating that such Regulatory Authority would oppose or not grant or
issue its Consent, if required, with respect to the transactions contemplated by
this Agreement and the other Operative Documents.

     1.06  Except as set forth on Schedule 1.06(a), no action of, or filing 
                                  ----------------
with, or Consent of, any Regulatory Authority is required by NOVA Corp or NOVA
to authorize, or is otherwise required in connection with, the execution and

have been obtained. Except as disclosed on Schedule 1.06(b), no filing with, or 
                                           ---------------- 
Consent of, any third party is required by virtue of the execution of this
Agreement or any other Operative Document by NOVA Corp or NOVA, or the
consummation of the transactions contemplated herein by NOVA Corp or NOVA, to
avoid the violation or breach of, or Default under, the terms of any Law,
Permit, Order or Contract to which NOVA Corp or NOVA or any of their
subsidiaries is a party or to which any of their respective Assets is subject.
Neither NOVA Corp nor NOVA has received notice from any third party indicating
that such third party would oppose or not grant or issue its Consent, if

                                      -2-
<PAGE>
 
required, with respect to the transactions contemplated by this Agreement and
the other Operative Documents.

     1.07  Except as set forth in Schedule 1.07, there is no Litigation relating
                                  -------------                                 
to NOVA's Merchant Business (including Litigation conducted by or related to any
Payment Network) that is pending or, to the knowledge of NOVA, threatened
against NOVA Corp or NOVA that, if adversely determined, would have a Material
Adverse Effect on NOVA Corp or NOVA.  Schedule 1.07 indicates which of such

                                                                      --------

the conduct by NOVA of its Merchant Business, except where the failure to have
the Permits does not and will not have a Material Adverse Effect.


                                  ARTICLE II

                        REPRESENTATIONS AND WARRANTIES
                                  OF KEYBANK

     KeyBank represents and warrants to NOVA Corp and NOVA as follows:

     2.01  KeyBank is duly organized and validly existing as a national banking
association under the laws of the United States, and has due authority to
conduct the KeyBank Merchant Business in all states where it conducts the
KeyBank Merchant Business, except where the failure to have such authority has
not and will not have a Material Adverse Effect.  POSSI is duly organized,
validly existing, and in good standing as a corporation under the laws of the
State of Ohio and has due authority to conduct its business in all states where

not and will not have a Material Adverse Effect.

     2.02  The execution and delivery of this Agreement and the consummation of
the transactions herein contemplated do not conflict in any material respect
with, or constitute a material breach or Default under, the organizational
documents of KeyBank or POSSI or under the terms and conditions of any Contract
to which KeyBank or POSSI is a party.

     2.03  The terms of the Assigned Agent Bank Agreements, the Assigned Agent
Bank Merchant Agreements, the Assigned Third Party Agreements, and the Assigned
Merchant Agreements and the KeyBank Merchant Regulations comply in all material
respects with applicable Laws, Orders and Permits.  With respect to the KeyBank

                                      -3-
<PAGE>
 
Merchant Business generally, KeyBank and POSSI are not, and have not been, in
material violation of any applicable Law, Order or Permit.

     2.04  KeyBank is a principal member in good standing of the Credit Card
Associations. KeyBank and the KeyBank Merchant Business complies in all material
respects with all applicable rules, regulations and certification requirements
of the Credit Card Associations, including but not limited to applicable "Year
2000" certification requirements.  KeyBank has provided (or will provide prior
to Closing) NOVA with true, complete, and correct copies of all Contracts
between KeyBank and any of the Credit Card Associations.

     2.05  KeyBank has not received notice from any Regulatory Authority
indicating that such Regulatory Authority would oppose or not grant or issue its
Consent, if required, with respect to the transactions contemplated by this
Agreement and the other Operative Documents.

     2.06  Except as set forth on Schedule 2.06 and except with respect to the
                                  -------------                               
POSSI Assets, KeyBank is the owner of, and has good and valid title to, the
Contributed Assets, free and clear of all Liens.  Without limiting the
generality of the foregoing, no Person other than KeyBank has any right, title,
or interest in the Contributed Assets except for (i) Merchants with respect to
Merchant Agreements to which they are a party, (ii) Agent Banks with respect to
the Agent Bank Agreement to which they are a party and with respect to any Agent
Bank Merchant Agreement to which they are a party, (iii) any third parties with
respect to the Assigned Third Party Agreements to which they are a party, (iv)
POSSI with respect to the POSSI Assets and (v) Merchants with respect to the
POSSI Equipment Leases to which they are a party.  POSSI is the owner of, and
has good and valid title to, all of the POSSI Assets , other than POSSI Assets
disposed of by POSSI since September 30, 1997 in the ordinary course of
business.  All of the POSSI Assets will be assigned to the Company pursuant to
the Assignment and Assumption Agreements.

     2.07  The KeyBank Merchant Business Financial Statements fairly present the
financial condition of the KeyBank Merchant Business as of their respective
dates, and the results of its operations for the periods indicated, in
accordance with GAAP applied on a consistent basis throughout the periods
involved, subject, in the case of any interim financial statements, to normal
year-end adjustments, none of which are reasonably likely to be, either
individually or in the aggregate, material in amount, and, in the case of 1996
financial statements, for the realization of $1.56 million in gain from the sale
of assets to POSSI, which may not have been in accordance with GAAP.  The
KeyBank Merchant Business has no Liabilities required to be disclosed by KeyBank
in financial statements prepared in accordance with GAAP applied on a basis
consistent throughout the periods involved other than (i) Liabilities disclosed
in the KeyBank Merchant Business Financial Statements, (ii) Liabilities for
which KeyBank has made adequate reserves as reflected in the KeyBank Merchant
Business Financial Statements, and (iii) Liabilities, ordinary in nature and
amount, incurred since September 30, 1997 in the ordinary course of business.
To the Knowledge of KeyBank,  there is no basis for a material write-down in the
value of the Assets shown in the KeyBank Merchant Business Financial Statements.

                                      -4-
<PAGE>
 
Since September 30, 1997, there has been no Material Adverse Effect on the
KeyBank Merchant Business.

     2.08  The information relative to Merchants' (i) Credit Card sales volume
and (ii) Debit Card sales volume set forth on Schedule 2.08 is accurate and
                                              -------------                
complete in all material respects as of the date hereof and for the periods
indicated.

     2.09  Schedule 2.09 lists each of the Agent Bank Agreements now in effect,
           -------------                                                       
each of which shall be assigned to the Company pursuant to the Assignment and
Assumption Agreements. KeyBank has provided (or will provide prior to Closing)
NOVA with true, complete, and correct copies of all such Agent Bank Agreements.
KeyBank has also made available to NOVA lists of all Merchants, including Agent
Bank Merchants, and will provide NOVA with updated lists of such Merchants as of
the Closing Date.  The Merchant Agreements with all such Merchants shall be
assigned to the Company pursuant to the Assignment and Assumption Agreements.
Except as set forth on Schedule 2.09, the Agent Bank Agreements and the Agent
                       -------------                                         
Bank Merchant Agreements are freely assignable by KeyBank without the consent of
the applicable Agent Bank.  KeyBank has no reason to believe that the rate of
fraud, Credit Loss, bankruptcy or termination with respect to the Merchant
Agreements or the Agent Bank Agreements will exceed rates experienced in the
past (except as may result from changes in general economic conditions).
KeyBank has not received or given any notice of material Default or termination
under, and has not received an adverse comment from any Regulatory Authority in

the "Workflow System") owned, licensed, leased, internally developed or
otherwise used in connection with the KeyBank Merchant Business.

     2.25  The value of all slow moving or obsolete Equipment reflected in the
consolidated balance sheet of the KeyBank Merchant Business has been written

utilized by Merchants that are included in the Contributed Assets are not
excessive and are reasonable in the present circumstances of the KeyBank
Merchant Business.

     2.26  The POSSI Balance Sheet fairly presents the financial condition of
POSSI as of September 30, 1997 in accordance with GAAP applied on a consistent
basis, subject to normal year-end adjustments, none of which are reasonably
likely to be, either individually or in the aggregate, material in amount.

statements prepared on that basis other than (i) Liabilities disclosed in the
POSSI Balance Sheet, (ii) Liabilities for which POSSI has made adequate reserves
as reflected in the POSSI Balance Sheet, and (iii) Liabilities, ordinary in
nature and amount, incurred since September 30, 1997 in the ordinary course of
business.  To the Knowledge of POSSI,  there is no basis for a material write-
down in the value of the Assets shown in the POSSI Balance Sheet.  Since
September 30, 1997, there has been no Material Adverse Effect on POSSI.

     an election pursuant to Code Section 453(d) (the "Election Out of

     1998 ("Year 1"; the Merchant Business Gross Revenue attributable to Year 1*

     * For Year 1, the Merchant Business Gross Revenue will be annualized by
     multiplying the actual amount of such revenue by a fraction, the numerator
     of which is 365 and the denominator of which is the number of days during
     the period starting on the day immediately after the Closing Date and
     ending on December 31, 1998.

     On or before December 31, 1998, (i) if  the Estimated Year 1 Payment
     exceeds [*], NOVA shall pay the amount of the excess to KeyBank
     or (ii) if the Estimated Year 1 Payment is less than [*], KeyBank
     shall reimburse NOVA for the amount of the shortfall. On or before January
     31, 1999, the amount of the payment (the "Year 1 Payment") due to KeyBank
     based on the actual Year 1 Merchant Business Gross Revenue will be
     determined, and (x) if the Year 1 Payment exceeds the Estimated Year 1
     Payment, NOVA shall pay the amount of the excess to KeyBank or (y) if the
     Year 1 Payment is less than the Estimated Year 1 Payment, KeyBank shall
     reimburse NOVA the amount of the shortfall.

         (b) YEAR 2 PAYMENT. On January 1, 1999, NOVA shall make a preliminary

     estimate of the portion of the purchase price payable to KeyBank with

     calculated based on an estimate of the Merchant Business Gross Revenue
     attributable to the Company's Merchant Business during the year ended
     December 31, 1999 ("Year 2"; the Merchant Business Gross Revenue
     attributable to Year 2 being the "Year 2 Merchant Business Gross Revenue").

     calculated based on an estimate of the Merchant Business Gross Revenue
     attributable to the Company's Merchant Business during the year ended

     Payment") due to KeyBank based on the actual Year 3 Merchant Business Gross

     Gross Revenue, Year 2 Merchant Business Gross Revenue, and Year 3 Merchant
     Business Gross Revenue, as set forth in the following table:

         Date, any Company Employee is terminated as a "Result of Reduction in
         Staff," and not as as result of "Discharge for Cause" or "Voluntary

         Pay Plan, which is attached hereto as Exhibit 7.08(a)(vi), such Company

discontinuance of any of such Retained Third Party Agreements; provided that,
notwithstanding anything to the contrary herein or in any other Operative

responsibility for such Termination Fees exceed $4,000,000.  Any and all
Termination Fees in excess of $4,000,000 shall be the sole responsibility of,

Company.

     7.11  WORKING CAPITAL REQUIREMENTS.  Unless and until other financing can
be arranged (but in no event longer than six months after the Closing Date),
NOVA will lend to the Company and POSSI all funds necessary to meet their normal
working capital requirements.  The interest rate or rates charged by NOVA to the
Company and POSSI will, from time to time, be the same as the interest rate or
rates charged to NOVA under its principal credit facility for loans made to NOVA
at the same time or times as the loans are made by NOVA to the Company.  To the
extent permitted by NOVA's principal bank lender, the loans by NOVA to the
Company and POSSI will be unsecured.  At the Closing, the Company, POSSI and
NOVA will execute and deliver a credit agreement, containing commercially
reasonable terms, governing the loans by NOVA to the Company and POSSI (the
"Credit Agreement").

                               ARTICLE IX

                  SURVIVAL OF REPRESENTATIONS AND WARRANTIES;
                  -------------------------------------------
                                INDEMNIFICATION
                                ---------------

     9.01  SURVIVAL OF REPRESENTATIONS AND WARRANTIES.  The representations and
warranties made by KeyBank and NOVA in this Agreement shall survive until March
31, 1999; provided that, if one party gives the other parties written notice
identifying a breach of any such representation or warranty before March 31,
1999, the matter identified in the notice will survive until it is resolved in
accordance with the provisions hereof.

     9.02  KEYBANK'S OBLIGATION TO INDEMNIFY.  Subject to the limitations in
Sections 9.01 and 9.05, from and after the date hereof, KeyBank shall indemnify,
defend and hold harmless the NOVA Entities and the Company, and their respective
directors, officers, employees and Representatives, from and against any and all
actions, claims, losses, Credit Losses, Chargebacks, costs, Liabilities,
damages, deficiencies, diminution in value, and expenses (including reasonable
attorneys' fees and other costs of litigation) (collectively, "Claims")
resulting from or arising out of any misrepresentation, breach of, or inaccuracy
in, any of the representations or warranties made by KeyBank in this Agreement
or the breach by KeyBank of any of its obligations under this Agreement.

     9.03  NOVA CORP AND NOVA'S OBLIGATION TO INDEMNIFY.  Subject to the
limitations in Sections 9.01 and 9.05, from and after the date hereof, NOVA Corp
and NOVA shall jointly and severally indemnify, defend and hold harmless the Key
Entities and the Company, and their respective directors, officers, employees
and Representatives, from and against any and all Claims resulting from or
arising out of any misrepresentation, breach of, or inaccuracy in, any of the
representations or warranties made by NOVA Corp or NOVA in this Agreement or the
breach by NOVA Corp or NOVA of any of its obligations under this Agreement.

     9.04  PROCEDURE FOR THIRD-PARTY CLAIMS.  Promptly after a party to whom an
indemnification obligation is owed hereunder (an "Indemnified Party") receives
notice of the commencement of any action or proceeding (a "Proceeding") in
respect of which indemnification may be sought hereunder, the Indemnified Party
will notify the party that is obligated to indemnify hereunder (an "Indemnifying

                                      -24-
<PAGE>
 
Party"); but the omission so to notify the Indemnifying Party shall not relieve
the Indemnifying Party from any obligation hereunder unless, and only to the
extent that, such omission results in the Indemnifying Party's forfeiture of
substantive rights or defenses.  If any such Proceeding shall be brought against
the Indemnified Party, the Indemnifying Party shall, upon written notice given
within a reasonable period of time following the Indemnified Party's notice to
the Indemnifying Party of any such Proceeding, be entitled to assume the defense
thereof at its own expense with counsel chosen by the Indemnifying Party and
reasonably satisfactory to the Indemnified Party; provided that any Indemnified
Party may, at its own expense, retain separate counsel to participate in such
defense.  Notwithstanding the foregoing, the Indemnifying Party shall not,
without the prior written consent of the Indemnified Party, settle, compromise
or consent to the entry of any judgment in any pending or threatened Proceeding
unless the settlement, compromise or judgment entry includes an unconditional
release of the Indemnified Party hereunder from all liability arising out of
such Proceeding.

     9.05  DEDUCTIBLE; CAP.  Notwithstanding the foregoing, no party will be
required to indemnify any other parties for any Claims with respect to a breach
of the representations and warranties hereunder unless the aggregate amount of
such Claims to which such party is obligated to indemnify exceeds $250,000.
Once the aggregate amount of such Claims exceeds $250,000, the amount of
indemnification that the party is required to pay hereunder will be limited to
the excess of the aggregate amount of the Claims over $250,000; except that, no
such limitation will apply to Claims caused by the fraud of the party required
to pay the indemnification.  No party will be required to pay indemnification
hereunder in excess of [*].

     officers, employees, and Representatives to keep confidential and not
     disclose, any of the terms and conditions of this Agreement or any other
     Operative Document to any third party without the prior written consent of
     the other parties to this Agreement and the other Operative Documents.  In

     Agreement.

         (b) The obligations of the parties hereunder shall survive and be

     documentation relating to the Contributed Assets as are reasonably related
     to the KeyBank Merchant Business or the enforcement of the Company's rights
     with respect to the Contributed Assets.  In each case, however, the books
     and records relating to the Contributed Assets for the period prior to the
     Closing Date, wherever located, that are held by a party hereto or under
     the control of a party hereto (the "Inspected Party") shall be open for
     inspection by the other parties, and such other parties' authorized agents
     and representatives and regulators may, at such other parties' own expense,
     make such copies of any excerpts from such books, records and documents as
     it shall reasonably deem necessary; provided that any such inspection: (i)
     shall be conducted during normal business hours from time to time
     reasonably established by the Inspected Party; (ii) shall, if the Inspected
     Party so requests, be conducted in the presence of an officer or designated

     maintained by the Company or by KeyBank, as the case may be, for a period
     of seven (7) years after the termination of the Operating Agreement, unless
     the parties shall, applicable Law permitting, agree upon a shorter period;
     provided that, in the event, as of the end of such period, any taxable year
     of the Company, NOVA or KeyBank is still under examination or open for
     examination by any taxing authority and that party has given notice of that
     fact to the other party, such books and records shall be maintained (or,
     alternatively, delivered by the Inspected Party to the other party) until
     the date, determined reasonably and in good faith, specified for
     maintenance of such records in such notice.  Prior to the destruction of
     any books and records relating to the Contributed Assets, the party in
     possession of such books and records shall offer them to the other party
     hereto.


                               ARTICLE XI

                     MEDIATION AND ARBITRATION OF DISPUTES

     11.01  MEDIATION AND ARBITRATION.

         (a) In the event of any dispute, claim, question or disagreement
     arising out of or relating to this Agreement, other than a matter for which
     a party is entitled to seek specific performance or injunctive relief as
     expressly provided herein, the parties shall use reasonable efforts to
     settle such dispute, claim, question or disagreement. To this end, they
     shall consult and negotiate with each other, in good faith, and,

                                      -27-
<PAGE>
 
     recognizing their mutual interests, attempt to reach a just and equitable
     solution satisfactory to both parties.   If settlement is not reached
     within thirty (30) days after written notice of the dispute, claim,
     question or disagreement is first given by one party to the other parties,
     the Chief Executive Officers, Chief Financial Officers or other comparable
     executive officers of KeyBank and NOVA shall consult with each other in an
     effort to resolve the matter (provided that  in no event shall the officers
     designated by each party be Committee Members).

         (b) If the parties do not reach such a solution within a period of
     thirty (30) days after the matter is referred to the executive officers for
     resolution, then the parties agree first to endeavor in good faith to
     amicably settle their dispute by mediation in accordance with the CPR Model
     Procedure for Mediation of Business Disputes, promulgated by the Center for
     Public Resources, New York City.

         (c) If mediation is unsuccessful within a reasonable time after
     commencement of mediation, but not in any event more than sixty (60) days
     thereafter, the mediator shall so certify, and the dispute shall be
     submitted to binding arbitration conducted in accordance with the CPR Rules
     for Non-Administered Arbitration of Business Disputes.  Any controversy or
     dispute shall be arbitrated by a single arbitrator either mutually agreed
     upon by the parties or, absent agreement, appointed in accordance with the
     aforesaid CPR rules.  No mediator under subsection (b) above may serve as
     an arbitrator.  The arbitration shall be governed by the United States
     Arbitration Act, 9 USC (S)(S)1-16, and judgment upon the award may be
     entered by any court having jurisdiction thereof. The arbitrator shall have
     case management authority and shall resolve the controversy in a final
     award within 180 days from commencement of the arbitration action. All
     questions of arbitrability shall be resolved by the arbitrator appointed
     pursuant to this clause. The prevailing parties shall be entitled to
     receive an award of attorneys' fees incurred in connection with the
     arbitration and judicial proceedings related thereto. There shall be no
     appeal from the arbitral award, except for fraud committed by the
     arbitrator(s) in carrying out his duties under the aforesaid rules;
     otherwise the parties irrevocably waive their rights to judicial review of
     the claim or controversy.

         (d) Unless otherwise agreed by the parties, the situs for dispute
     resolution shall be Washington, D.C.

         (e) In the event that the Center for Public Resources no longer
     promulgates rules as set forth above, then the mediation or binding
     arbitration shall be administered under the rules of the American
     Arbitration Association or such other recognized rules for resolution of
     disputes as the parties may mutually agree.

     12.01  TERM.  This Agreement shall take effect on the date hereof and

     satisfy, and such other party is unwilling or unable to satisfy such
     conditions on or before June 30, 1998.

         (c) By either KeyBank or NOVA if the Closing has not occurred by June
     30, 1998.

Agreement pursuant to Section  12.02, this Agreement shall become void and have
no effect, except that the provisions of Articles IX, XI, and XIII, and Sections
10.01 and 10.02 shall survive any such termination.

     13.01  AMENDMENTS AND WAIVERS.  Except as otherwise expressly provided
herein, this Agreement shall not be amended, modified or waived in any fashion
except by an instrument in writing signed by the parties hereto.  Waiver by a
party of any breach of this Agreement by any other party shall not be effective
unless in writing, and no such waiver shall operate or be construed as the
waiver of the same or another breach on a subsequent occasion.

     13.02  NONASSIGNABILITY.  All terms and provisions of this Agreement shall
be binding upon and shall inure to the benefit of the parties hereto and their
respective successors and permitted assigns.  This Agreement may not be assigned
by any party without the prior written consent of the other parties; provided
that such consent shall not be required (a) for the assignment by any party of
its rights and privileges hereunder to a person or entity controlling,
controlled by or under common control with such party (it being understood that
no such assignment shall relieve the assigning party of its duties or
obligations hereunder), or (b) for the assignment and delegation by any party of

                       MERCHANT ASSET PURCHASE AGREEMENT

     THIS MERCHANT ASSET PURCHASE AGREEMENT (this "Agreement") is made and
entered into as of the 30th day of December 1997 by and between MBNA AMERICA
BANK, N.A., a national banking association ("MBNA") and NOVA INFORMATION
SYSTEMS, INC., a Georgia corporation ("NOVA").  For purposes of this Agreement,
capitalized terms used herein, unless otherwise defined herein, shall have the
meaning ascribed to such terms in the Definitional Supplement attached hereto as
Exhibit A (the "Definitional Supplement").

                            BACKGROUND AND PURPOSE:

     A.  MBNA is a party to certain Merchant Agreements with various Merchants,
who consist principally of retail and other providers of goods and services, and
is party to certain Affinity Agreements with various Affinity Associations
according to which agreements MBNA has agreed to provide certain services which
constitute MBNA's Merchant Business.

     B.  MBNA wishes to sell and transfer to NOVA all of its rights under the
Assigned Merchant Agreements , and MBNA wishes to sell and transfer to NOVA
certain other assets utilized in connection with the Merchant Business, and NOVA
is willing to accept such rights and assets and to assume the duties,
responsibilities and liabilities relating to certain rights under the Affinity
Agreements and under the Merchant Agreements with respect to its purchase of
the Merchant Business.  MBNA and NOVA are willing and able, additionally, to
undertake and perform certain other obligations pursuant to and in connection
with this Agreement, subject to the terms and conditions hereof.

     C.    MBNA and NOVA will enter into a Marketing Agreement pursuant to which
NOVA will make quarterly payments to MBNA based upon the volume of business
generated from the Merchant Business.  MBNA will  also be paid a referral fee
under the Marketing Agreement for each new Merchant directly or indirectly
introduced to NOVA by MBNA.  Additionally, as an integral part of the
transactions contemplated hereunder MBNA and NOVA will enter into a Non-
Competition Agreement.

                                 THE AGREEMENT

     NOW, THEREFORE, in consideration of the mutual agreements contained in this
Agreement and other good and valuable consideration, the receipt and sufficiency
of which hereby are acknowledged, MBNA and NOVA hereby agree, on the terms and
conditions herein set forth, as follows:


                                 ARTICLE  I

                    ASSETS SOLD; ASSUMPTION OF LIABILITIES

     1.1  SALE AND PURCHASE.  On  the terms and subject to the conditions set
forth in this Agreement, and effective as of December 31, 1997 (the "Effective
Date"), MBNA hereby sells, transfers and assigns to NOVA and NOVA hereby
purchases, assumes and accepts from MBNA, all right, title and interest of MBNA
in and to the following tangible and intangible assets and interests
(collectively, the "Assets Sold"):

           all rights and interests of MBNA under the Assigned Merchant
         Agreements arising on or after the Effective Date, and all  books,
         records and documents relating solely thereto (as further specified in
         Section 1.5 hereof); for greater clarity such list will include,
         without limitation, all Merchant Agreements with Affinity Merchants;
<PAGE>
 
           to the extent assignable by MBNA and/or as agreed by any Affinity
         Association, the rights relating to the provision of and marketing of
         Merchant Services under the Affinity Agreements arising on or after the
         Effective Date subject to the terms and conditions set forth in the
         Affinity Agreements (the "Assigned Affinity Rights", which are set
         forth  on Schedule 1.1(b)(i) attached hereto), and copies of the
                   ------------------                                    
         Affinity Agreements (as further specified in Section 1.5 hereof);

          to the extent such Affinity Rights are not assignable, MBNA will use
            commercially reasonable best efforts (consistent with maintaining a
            positive relationship between MBNA and the Affinity Association) to
            make sure that NOVA will have the ability to exercise, through MBNA
            or otherwise as may be agreed by the parties, the Affinity Rights
            relating to the Affinity Agreements, subject to the conditions and
            exceptions outlined in the Affinity Agreements (each Merchant,  (x)
            that is a party to an Assigned Merchant Agreement as set forth in
            Section 1.1(a) above, or (y) that is  related to an Affinity
            Association whose Assigned Affinity Rights are being transferred to
            NOVA as set forth in Section 1.1(b), or (z) that is related to an
            Affinity Association and Affinity Agreement as set forth in this
            Section 1.1(c),  being referred to herein collectively as an
            "Assigned Merchant".   The  Assigned Merchants who have aprocessed
            application as of November 30, 1997 are identified on Schedule
                                                                  --------
            1.1(c)).   Schedule 1.1(c) shall be updated during the Transition
            -------                                                          
            Period to show each Assigned Merchant as of the Effective Date.);

          an unlimited, perpetual, non-exclusive (provided that MBNA, its
            affiliates or subsidiaries,  shall not use for the benefit of
            others, or grant to others any right to use the Software, for
            Merchant Services), freely transferable and royalty free license to
            use the Software.  MBNA will provide the ancillary written
            materials, to the extent owned by MBNA, necessary for NOVA to
            construct an operating system to run the software which are set
            forth on Schedule 1.1(d)(i).  On the date mutually agreed by the
                     -------------------                                    
            parties as part of the conversion process, MBNA will provide a
            complete copy of the current source code version of the Software
            (and all  documentation in the possession of MBNA relating thereto)
            in the form or forms reasonably agreed to by the parties, which is
            compatible or can be made compatible with the computer system being
            used by NOVA and which, when compiled, will produce, along with the
            necessary third party licensed materials, the object code version of
            the software for use with the Merchant Business (the specifications
            of the Software are set forth on Schedule 1.1(d)(ii), "Software
                                             -------------------

     1.2  TRANSFER AND ASSUMPTION OF ASSETS SOLD AND ASSUMED LIABILITIES.  On
the Effective Date, NOVA shall assume all liability for the Assumed Liabilities
and agrees to pay, satisfy and discharge when due any obligation relating to
such Assumed Liabilities.  Assumption of the Assumed Liabilities by NOVA, and
the assignment, transfer and conveyance of the Assets Sold by MBNA, shall be
effected by written instrument in the form of Exhibit 1.2(a) attached hereto
                                              --------------                
(the "Assignment and Assumption Agreement").  In addition to the Assignment and
Assumption Agreement, the sale, conveyance, transfer, assignment and delivery of
the Assets Sold by MBNA to NOVA shall be effected by written instrument or
instruments in the form or forms attached hereto as Exhibit 1.2(b)  (the
                                                    --------------      
"Transfer Documents").

     1.3  LIABILITIES. Except as expressly assumed by NOVA in the Assignment and
Assumption Agreement, it is understood and agreed that NOVA shall not assume or
become liable for the payment of any debts, liabilities, losses, bank
indebtedness, mortgages, or other obligations of MBNA, any Assigned Merchant, or
any Affinity Association.  In addition, NOVA shall not assume or become liable
for Credit Losses, charge backs, accounts payable, Affinity Association
compensation, interchange, or other merchant transaction charges, whether the
same are known or unknown, now existing or hereafter arising, of whatever nature
or character, whether absolute or contingent, liquidated or disputed, to the
extent any liability arises from merchant transactions or other acts or
omissions relating to the Merchant Business prior to the Effective Date;
provided, however, that in no event shall the wording of this Section 1.3 be
deemed to alter or modify in any way the definition of "Assumed Liabilities" or
the liabilities being assumed by NOVA pursuant to such definition.

     1.4  CONSENT AND ASSIGNMENT.

         (a) MBNA, to the extent necessary and in cooperation with NOVA, from
     and after the Effective Date and during the Transition Period, shall use
     commercially reasonable efforts to assist NOVA in obtaining, at NOVA's
     expense, (i) the agreement of the Assigned Merchants and the Affinity
     Associations to the continuation of the Merchant Business with NOVA under
     the Assigned Merchant Agreements, the Affinity Agreements and/or the
     Assigned Affinity Rights, as contemplated by this Agreement, (ii) the
     consent of the Assigned Merchants, and the Affinity Associations, as
     appropriate, to NOVA's conversion of the Assigned Merchants to such
     clearing bank and merchant accounting system as NOVA may specify, and (iii)
     the consent of the Assigned Merchants, and the Affinity Associations, as
     appropriate, to NOVA's conversion of the Assigned Merchants to NOVA's
     network.  Any additional documentation, other than the Transfer Documents,
     to be executed by MBNA, which NOVA currently deems to be required to
     accomplish the goals set forth in this Section 1.4(a), has been provided by
     NOVA as Exhibit 1.4(a).
             -------------- 

         (b) Without limiting the generality of the foregoing, promptly
     following the Closing,  NOVA shall deliver to each of the Assigned
     Merchants a notice, in a form mutually agreed upon by NOVA and MBNA, of the
     assignment by MBNA, as of the Effective Date, of all rights in and to said
     Assigned Merchant Agreements and the Assigned Affinity Rights to NOVA.  The
     notice shall be on the letterhead of MBNA.  Such notice may inform each
     Assigned Merchant of NOVA's intention to convert the Assigned Merchant to
     NOVA's network, as well as to a clearing bank and merchant accounting
     system designated by NOVA.
<PAGE>
 
         1.5  BOOKS AND RECORDS.

         (a) As soon after the Closing Date as is practicable, and in no event
     later than the conclusion of the Transition Period, MBNA shall cause to be
     delivered to NOVA the "merchant file" for each of the Assigned Merchant
     Agreements, which shall contain, at a minimum, (i) the original, executed
     application or telemarketed faxed application for such Merchant, (ii) the
     credit bureau report relating to such application and (iii) the credit
     approval sign-off for such application and may contain other related
     materials, including but not limited to the original, true, correct and
     complete executed Merchant Agreement.  Prior to the Closing Date, MBNA will
     cause to be delivered to NOVA (I) either (i) the Affinity Agreement with
     respect to any Assigned Affinity Rights or a copy of the Affinity Agreement
     or a redacted version of the Affinity Agreement which contains all relevant
     clauses relating to the rights and liabilities of the provider of Merchant
     Services for the Affinity Merchants (such file will reference the exact
     number of pages being delivered in such file, so that NOVA may check as to
     completeness); and (II) the materials relating to the Merchant Business
     attached hereto as Schedule 6.6(a) and the other schedules attached to this
                        ---------------                                         
     Agreement.  In each case, however, the books and records relating to the
     Assets Sold for the period prior to the Closing Date, wherever located,
     that are held by a party hereto or under the control of a party hereto (the
     "Inspected Party") shall be open for inspection by the other party, and
     such other party's authorized agents and representatives and regulators
     may, at such other party's own expense, make such copies of any excerpts
     from such books, records and documents as it shall reasonably deem
     necessary; provided, however, that any such inspection: (a) shall be
     conducted upon at least three business days prior written notice, during
     normal business hours from time to time reasonably established by the
     Inspected Party, subject to the safety, security and operating procedures
     of the Inspected Party, including but not limited to the party conducting
     the inspection or any third party agent executing such confidentiality
     agreements as the Inspected Party may reasonably request; (b) shall, if the
     Inspected Party so requests, be conducted in the presence of an officer or
     designated representative of the Inspected Party; and (c) provided that
     nothing herein shall be deemed to grant to either the party conducting the
     inspection or any other third party the right to inspect or review any
     books, records or documents regarding such Inspected Party's general
     operations or results or books records or documents which do not
     specifically relate to the Merchant Business, and the Inspected Party may
     segregate or delete such information and other information deemed by it to
     be immaterial or irrelevant from such books, records and documents.  If the
     Operative Documents are terminated in accordance with Section 8.4 hereof,
     any copies or excerpts or work product shall be returned or destroyed at
     the request of the Inspected Party.

         (b) All books and records relating to the Assets Sold shall be
     maintained by NOVA, or MBNA, as the case may be, pursuant to their current
     document retention policies and procedures.   To the extent that a party
     has given notice of the fact that it would require documents to be kept for
     a longer period by the other party, to the extent feasible, as specified or
     allowed by such party's policies and procedures, such books and records
     shall be maintained (or, alternatively, delivered by the Inspected Party to
     the other party) until the date, determined reasonably and in good faith,
     specified for maintenance of such records in such notice.

"Closing") shall take place on December 30, 1997, or on such other date at such
other time and place as the parties shall agree in writing (the "Closing Date"),
to be effective as of the Effective Date, and shall take place through the
execution and exchange, via facsimile transmission, of this Agreement and the
Operative Documents.  The parties acknowledge and agree that upon mutual
exchange and receipt of signature pages via facsimile, and upon receipt by MBNA
of the wire transfer hereby contemplated, this Agreement and the Operative
Documents delivered in connection herewith shall be deemed effective, and the
transactions hereby contemplated shall be deemed consummated, notwithstanding
any parties failure or refusal to deliver original (i.e. non-facsimile)

                                 ARTICLE  III

                               TRANSITION PERIOD

     3.1  ORDERLY TRANSITION.  MBNA and NOVA covenant and agree to cooperate
with each other using their commercially reasonable efforts, to effect an
orderly transition of the Merchant Business during the Transition Period in
respect of the Assets Sold and the Assumed Liabilities, including, but not
limited to, fulfilling their respective obligations under Section 1.4 hereof.

     3.2  SERVICES DURING THE TRANSITION PERIOD.

         (a) During the Transition Period, MBNA shall perform, on behalf of and
     for the account of NOVA, at the same location(s) presently used to conduct
     the Merchant Business, all of the services (the "Transition Services", as
     are identified on Schedule 3.2 attached hereto).  Upon prior notice to MBNA
                       ------------                                             
     and with the prior consent of MBNA, which consent may not be unreasonably
     withheld, NOVA may make reasonable adjustments to the Transition Services
     which do not increase either MBNA's expenses or liabilities.
     Notwithstanding anything to the contrary herein, MBNA shall be under no
     obligation to increase the allocation or commitment levels of personnel or
     resources used in performing the Transition Services beyond current
     staffing and resource levels.

         (b) MBNA shall perform the Transition Services substantially in the
     same manner and with the same degree of care as performed in connection
     with the Merchant Business prior to the Closing Date.  Without limiting the
     generality of the foregoing, during the Transition Period, MBNA shall
     continue to provide credit to Assigned Merchants on the same business day
     deposits are made by Assigned Merchants for Draft deposits (provided such
     deposits are made prior to 2:00 p.m. closing; Draft deposits made after
     2:00 p.m. closing shall be considered to be made on the following business
     day) and on the day of receipt of ACH notice for Credit Card transactions
     processed electronically.  MBNA shall not be entitled to reimbursement for
     its cost of funds in providing credit for Draft deposits.

         (c) During the Transition Period, in performing services hereunder,
     MBNA shall be in material compliance with the rules and regulations of the
     Credit Card Associations and the EFT Networks, and MBNA shall not take, or
     fail to take, any actions with respect to the Merchant Business which would
     constitute a violation of such rules and regulations.  The parties hereto
     acknowledge that MBNA will not be updating or incurring any costs to modify
     its existing electronic financial transaction processing equipment,
     software or policies relating to the Merchant Business after the Effective
     Date and, accordingly, MBNA will be responsible for, and shall pay, as
     assessed by the Credit Card Associations and/or EFT Networks, any related
     fines, penalties, adverse differences in interchange rates, or other
     liabilities related to or arising from such omissions or other
     noncompliance and its performance hereunder, arising prior to the
     termination of the Transition Period.

     3.3  REVENUE DURING THE TRANSITION PERIOD.

         (a) In performing services during the Transition Period (and during any
     extensions thereto pursuant to Section 3.6 hereof) on behalf of and for the
     account of NOVA, MBNA shall, beginning on the Effective Date and continuing
     throughout the Transition Period, collect (and pay in accordance with
     Section 3.3(b) below), with respect to original sales transactions
     occurring on or after the Effective Date, (i) revenue generated by the
     Merchant Business, (ii) minus (A) interchange fees, assessments, Affinity
     Association compensation, payments, Credit Losses and rebates, and (B)
     MBNA's expenses incurred in connection with providing such services
     (provided, however, that in no event shall MBNA charge NOVA such expenses
     in excess of [*] per transaction processed) (iii) plus a credit to such
     expenses on behalf of NOVA of [*] per month during the Transition Period,
     not to exceed an aggregate total credit of [*] (and to the extent
     necessary, any amount remaining of the aggregate total of [*] shall be
     credited in the last month of the Transition Period) (collections, net of
     expenses, as modified by credits, is referred to collectively herein as
     "Revenue"). With respect to clause 3.3(a)(ii)(B), to the extent MBNA's
     actual expenses during the Transition Period are reduced to a level that
     would be less than the [*] per transaction cap as provided therein, MBNA
     shall give NOVA the benefit of any corresponding reduction.

         (b) In connection with the Transition Period, MBNA shall pay to NOVA
     monthly, by the last business day of each such month, the Revenue generated
     during the immediately preceding month (each a "Payment Date").   Revenue
     shall include all original sales transactions and all other revenue
     generated by the Merchant Business occurring on or after the Effective Date
     during the Transition Period.   MBNA's obligation to make a payment to NOVA
     on the Payment Dates shall continue until all Revenue generated during the
     Transition Period is paid to NOVA.

         (c) At the time of each payment by MBNA to NOVA pursuant to Section
     3.3(b) above, or as soon thereafter as is practicable, MBNA shall furnish
     to NOVA an invoice in the form attached as Schedule 3.3(c) identifying all
                                                ---------------                
     expenses that have been withdrawn from Revenue for MBNA's expenses, the
     required credits and the amount due to NOVA, and a certificate of an
     authorized financial officer of MBNA certifying the withdrawn expenses, the
     credits and the amount due to NOVA and showing the calculation thereof.

     3.4  EMPLOYEES.  MBNA shall use commercially reasonable efforts to provide
adequate and appropriately skilled staffing in connection with the operation of
the Merchant Business during the Transition Period.  It is acknowledged by the
parties that as NOVA is scheduled to assume servicing responsibilities for the
Merchant Services during the Transition Period, MBNA shall be entitled to
decrease its staffing commitments (provided that the failure by NOVA to assume
servicing responsibilities as scheduled is not attributable to MBNA).  NOVA will
not make any offer of employment to, or actively solicit any employees of MBNA
or its affiliates to take positions at NOVA, until the Transition Period
terminates.

      CLEARING BANK ARRANGEMENT.

         (a) In order to permit an orderly transition of the processing of
     Credit Card transactions during the Transition Period, MBNA shall continue
     to act as a clearing bank for NOVA with respect to Credit Card transactions
     processed under the Assigned Merchant Agreements, all in material
     accordance with the rules and regulations of the Credit Card Associations
     and the EFT Networks, such responsibility to terminate on or prior to the
     Transition Date.

         (b) NOVA shall at its own expense prepare, and after good-faith
     consultation with MBNA, MBNA shall execute reasonably drafted documents
     which are non recourse with respect to transactions occurring on or after
     the assignment of the clearing responsibilities, to evidence the transfer
     of the clearing bank responsibilities under the Assigned Merchant

                     [*] CONFIDENTIAL TREATMENT REQUESTED.

<PAGE>
 
     Agreements to the person designated by NOVA to effect such transfer.  In
     addition, MBNA shall render such other necessary assistance as NOVA may
     reasonably request, at NOVA's sole expense.  NOVA shall choose a clearing
     bank which in NOVA's reasonable judgment is not a competitor of MBNA's and
     can perform any required functions (a "Permitted Clearing Bank"), provided,
     however, that in any event, each of Bank of America, Firstar Bank, First
     Union, KeyCorp and Regions Bank (and their respective affiliates and
     subsidiaries) are and shall be deemed by the parties hereto to be Permitted
     Clearing Banks.  MBNA shall use commercially reasonable efforts to provide
     to NOVA all information necessary for such transfer (for example, a
     Merchant Master File Dump on disk in ASCII format).

     3.6  EXTENSION OF TRANSITION PERIOD.  If requested by NOVA in writing at
least fifteen (15) days prior to the Transition Date, MBNA shall continue to
provide any of the services described in this Article III as are requested by
NOVA beyond the Transition Date, on the same terms and conditions set forth
herein, for up to thirty days after the Transition Date, as specified in such
written notice.

     3.7  TAXES.  NOVA will be liable for any transfer (including sale and use)
taxes associated with the transfer of the Assets Sold.  All other Taxes will be
borne by the party to whom the taxing authority imposes ultimate liability.

                                 ARTICLE  IV

records which are retained or obtained by it pursuant to Section 1.5, and all
information learned or obtained about the Business or relating to the Merchant
Business, as confidential and will not disclose such information to third
parties except as required by law, as needed in connection with a lawsuit,
claim, litigation or other proceeding or in connection with tax or regulatory
matters and except to the extent that such information is already in the public
domain, or subsequently enters the public domain, other than as a result of the
breach of MBNA's obligations under this Section 4.1.  MBNA and its officers,
employees, agents and representatives shall not use the information described in
this Section 4.1 in any manner that might reasonably be anticipated to adversely
affect the Merchant Business or NOVA's relations with the Assigned Merchants or
with other persons or entities (except that if a partial repurchase under
Section 8.4 occurs or if a repurchase and termination of this Agreement under
Section 8.5 occurs, MBNA may use such information and treat it as it would in
the ordinary course of its business, as currently conducted).

     4.2  NOTICE OF BREACH OR POTENTIAL BREACH.  MBNA shall promptly notify NOVA
of any change, circumstance or event which may prevent MBNA from complying with
any of its obligations hereunder.

     4.3  FURTHER ASSURANCES.  On and after the Closing Date, MBNA shall (i)
give such further assurances to NOVA and execute, acknowledge and deliver all
such acknowledgments and other instruments and take such further action as NOVA
may reasonably request to effectuate the transactions contemplated by this
Agreement, including the transfer of the Assets Sold and the assumption by NOVA
of the Assumed Liabilities, and (ii) use commercially reasonable efforts to
assist NOVA in the orderly transition referred to in Article III.  All  expenses
incurred by MBNA in complying with NOVA's requests pursuant to this Section 4.3
shall be reimbursed to MBNA by NOVA.

     4.4  SCHEDULE UPDATES.  MBNA agrees to update the Schedules identified on
Schedule 4.4 attached hereto within 90 days of the expiration of the Transition
- ------------                                                                   
Period.
<PAGE>
 
     4.5  COLLECTIONS.  During the first 180 days following the Transition Date,
MBNA shall use commercially reasonable efforts to assist NOVA, at NOVA's
request, in processing amounts in respect of any charge-back or other Credit
Loss received or identified in connection with the Merchant Business and
relating to or arising out of any original sales transaction occurring on or
after the Effective Date.  NOVA shall reimburse MBNA and be responsible for all
costs and expenses relating to such collection efforts, including costs and
expenses of collection letters, litigation, arbitration proceedings and similar
actions.

     4.6  POST-TRANSITION PROCESSING.  MBNA covenants and agrees that:

         (a) MBNA shall, for the period beginning upon the expiration of the
     Transition Period, and continuing until the effective date of the
     expiration or termination of the Marketing Agreement (the "Post-Transition
     Period"), and unless otherwise agreed upon in writing by NOVA and MBNA,
     accept Drafts from all MBNA Merchants, and only such MBNA Merchants, whose
     Merchant Agreements permit Draft deposits, as well as from any Merchants
     (whose Merchant Agreements permit Draft deposits) which are referred by
     MBNA to NOVA pursuant to the Marketing Agreement.  Such Drafts shall be
     handled in accordance with NOVA's reasonable instructions, including using
     commercially reasonable efforts to ship each day's batches of Drafts at the
     end of the business day (or such other periodic delivery as may be agreed
     upon by the parties), via overnight courier delivery to the draft capture
     vendor designated by NOVA, the expense of such shipment to be paid by NOVA
     (collectively, the "Overnight Delivery Obligation").  Both parties
     acknowledge that MBNA will not be deemed in breach of this Agreement with
     respect to its Overnight Delivery Obligation to the extent that 90% or more
     (as measured by total volume over time) of the Drafts are sent to the draft
     capture vendor designated by NOVA within three business days of receipt by
     MBNA; and

         (b) MBNA, throughout the Post-Transition Period, shall use NOVA and a
     principal member designated by NOVA as the exclusive processor of Cash
     Advance Transactions made by MBNA; and

           MBNA shall receive no additional remuneration from NOVA, beyond the
         payments due MBNA under the Marketing Agreement, in connection with the
         performance of the services set forth in this Section 4.6.

     4.7  AFFINITY AGREEMENTS.  MBNA covenants and agrees that it shall not
amend any Affinity Agreement in any way that may alter NOVA's rights and
obligations, performance, related or otherwise, under the Affinity Agreements,
or that may increase or alter NOVA's liability or expense, other than upon
NOVA's prior written consent (which consent shall not be unreasonably withheld
or delayed).

     MBNA hereby makes the following representations and warranties to NOVA as
of the date hereof and as of the Effective Date:
<PAGE>
 
     6.1  ORGANIZATION.  MBNA is a national banking association duly chartered

connection with this Agreement or the transactions contemplated hereby.

                                 ARTICLE  VIII

                           COVENANTS OF THE PARTIES

     MBNA and NOVA hereby covenant and agree as follows:

     8.1  CREDIT CARD ASSOCIATION FILINGS.  NOVA shall file with the Credit Card
Associations and the EFT Networks any document or information that each such
Credit Card Association or EFT Network deems to be required or desirable to be
filed in order for the acquisition contemplated by this Agreement to be
completed, and MBNA shall cooperate with NOVA in that regard, at NOVA's sole
expense.

     8.2  EMPLOYEE BENEFITS PLANS.  To the extent that NOVA is in compliance
with Section 3.4 hereof, NOVA shall not adopt, assume or otherwise become
responsible for, either primarily or as a successor employer or otherwise, and
shall have no liability whatsoever with respect to, any "Controlled Group
Employee Benefit Plan" (i.e., any employee benefit plan (within the meaning of
ERISA (S)3(3)) or any other plan, policy, agreement or arrangement contributed
to or sponsored or maintained by, an MBNA Entity or any affiliate of an MBNA
Entity (an "MBNA Entity Affiliate"), or any such plan, policy, agreement or
arrangement for which an MBNA Entity or any MBNA Entity Affiliate could incur
liability. The preceding sentence applies to any liability with respect to a
Controlled Group Employee Benefit plan, regardless of whether such liability
involves Merchant Business Employees, and regardless of when or how such
liability arose. To the extent that NOVA, any successors or assigns thereto, and
any employees, officers, directors, agents, independent contractors and other
persons affiliated with the NOVA (the "Indemnitees") incur any liability
whatsoever with respect to any Controlled Group Employee Benefit Plan (whether
such liability be liability imposed under ERISA, the Code, or otherwise), the
MBNA Entities shall indemnify each such Indemnitee for all such liabilities
which result, and shall take any action reasonably requested by NOVA to prevent
the imposition of such liability. Notwithstanding any provision of this
Agreement to the contrary, the indemnification of the preceding sentence shall
survive the Closing and shall remain effective concurrent with the legal
limitations period applicable to such liability. Additionally, the MBNA Entities
agree not to assert that NOVA is a successor employer of any MBNA Entity or any
MBNA Entity Affiliate. In particular, NOVA shall not assume liability for any
group health continuation coverage or coverage rights under Section 4980B of the
Code or Part 6 of Title I of ERISA applicable to or arising with respect to any
group health plan sponsored and/or maintained by an MBNA Entity or any MBNA
Entity Affiliate at any time prior to or after the Closing Date. This provision
shall apply to any continuation coverage or coverage rights which arise due to
qualifying events which occur before, concurrently with or after Closing under
an MBNA Entity's group health plan or plans, and any continuation coverage or
coverage rights which result from an MBNA Entity's dissolution and/or trmination
of its group health plan or plans.

     8.3  APPLICATIONS; ANTITRUST NOTIFICATIONS.  MBNA and NOVA have filed with
the United States Federal Trade Commission ("FTC") and the United States
Department of Justice the notification and report form required for the
transactions contemplated hereby and any supplemental or additional information
which may reasonably be requested in connection therewith pursuant to the HSR
Act.  The filing fee incurred in connection with the HSR Act was paid fifty
percent (50%) by MBNA and fifty percent (50%) by NOVA, with NOVA paying the
$45,000 HSR Act filing fee (the "HSR Fee") on behalf of NOVA and MBNA, and MBNA
having reimbursed NOVA in the amount of $22,500.

     8.4  PORTFOLIO REPURCHASE.  During the term of the Non-Competition
Agreement or during the five year period following the Closing Date, whichever
is longer, in the event that (a) there occurs a Voluntary Bankruptcy Proceeding
or Involuntary Bankruptcy Proceeding with respect to NOVA (which is not
dismissed and continues unstayed or is in effect for a period of 60 consecutive
days), or (b) NOVA has merged with, or consolidated with (in circumstances where
NOVA is not the surviving entity, or NOVA's shareholders immediately prior to
such transaction hold less than 50% of the voting stock of the surviving entity
upon consummation of such transaction), or transferred all or substantially all
of its assets to an entity which at the time of consummation of such transaction
is both (i)  among the top ten issuers of credit cards in the United States of
America, as measured by managed credit card assets (or subsidiaries or
<PAGE>
 
affiliates  of such entities, or successors or assigns of such entities to the
extent such successors or assigns of such entities would as a result of such
succession or assignment, be among the top ten issuers of credit cards in the
United States of America, using as a benchmark for inclusion the managed credit
card assets for the tenth largest such entity, determined as set forth below),
as determined in the most current issue of The Nilson Report which sets forth
such information, or to the extent such report is no longer published, any other
similar publication, as reasonably agreed between the parties hereto; and (ii)
reasonably believed by MBNA to be national competitors in the affinity business,
MBNA shall have the option, exercisable at any time prior to the expiration of
thirty (30) days following receipt by MBNA of notice from NOVA of such event, of
terminating the Marketing Agreement and the Non-Competition Agreement and
repurchasing from NOVA all of the then existing Assets Sold, MBNA Merchants and
the rights and interests relating thereto (a "Portfolio Repurchase", with the
portfolio being repurchased referred to herein as the "Repurchased Portfolio").
The purchase price in connection with such Portfolio Repurchase shall be
determined by aggregating the Net Revenue attributable to the Assets Sold  and
the MBNA Merchants for the twelve month period preceding the Portfolio
Repurchase, and multiplying such amount by [*],  if such option is exercised
prior to December 31, 1998 and thereafter for the fair market value of the
assets to be repurchased.  The Portfolio Repurchase shall be consummated
pursuant to a purchase agreement, and such other transfer, assignment,
conveyance, documents, as well as pursuant to a reasonable and appropriate
transition and conversion plan, as the parties may mutually agree upon and as
are customary for transactions similar to the Portfolio Repurchase.   To
determine fair market value of the assets to be repurchased (with respect to
options exercised after December 31, 1998), MBNA and NOVA shall for a period of
fifteen days, negotiate in good faith in an effort to mutually agree on the fair
market value of the Repurchased Portfolio.   If such efforts fail to produce
agreement on a determination of the fair market value of the Repurchased
Portfolio, then the fair market value shall be determined by two appraisers, one
chosen by MBNA and one chosen by NOVA, both of whom must have reasonable
expertise in valuing merchant credit card portfolios.  If the two appraisal
values (each an "Appraisal") differ by ten per cent or less (such percentage
difference to be computed by subtracting the lesser of the Appraisal values from
the greater of the Appraisal values and dividing the difference by the greater
of the Appraisal values),  the  fair market value shall be equal to the average
of the two Appraisal values.  In the event that the two Appraisal Values vary by
more than ten percent, a third appraiser, who must have reasonable expertise in
valuing merchant credit card portfolios, shall be mutually agreed upon by the
first two appraisers, to conduct an independent appraisal and on the basis of
that independent appraisal, the third appraiser shall, in the exercise of his or
her professional judgment, determine which of the two Appraisals is the most
commercially reasonable, and that Appraisal shall be the fair market value of
the Repurchased Portfolio.

     8.5  SPECIFIED AFFINITY MERCHANT REPURCHASE.  To the extent that an
Affinity Association notifies MBNA or NOVA in writing (or otherwise, where both
parties have been notified by the Affinity Association in an unequivocal manner)
during the Transition Period that such Affinity Association will oppose the
orderly transition of the Merchant Business conducted by its Affinity Merchants
to NOVA and/or will attempt to hinder future marketing initiatives to its
members by NOVA (a "Dissenting Affinity Association") then no later than thirty
(30) days following the termination of the Transition Period, NOVA has the
option of terminating the Operative Documents with respect to such Affinity
Associations and Affinity Merchants and requiring MBNA to repurchase such
Affinity Merchants and all of NOVA's right, title and interest in any related
Affinity Rights (a "Partial Portfolio Repurchase").  The purchase price to be
paid by MBNA to NOVA in connection with such Partial Portfolio Repurchase shall
be determined by aggregating the Net Revenue for the twelve months immediately
preceding the Closing Date attributable to all such Affinity Merchants as
identified in the notification, and multiplying such amount by [*]. The
Partial Portfolio Repurchase shall be consummated pursuant to a purchase
agreement, and such other transfer, assignment, conveyance, documents, as well
as pursuant to a reasonable and appropriate transition and conversion plan, as
the parties may mutually agree upon and as are customary for transactions
similar to the Partial Portfolio Repurchase. The provisions of this Section 8.5
will not apply to any Dissenting Affinity Association as to which NOVA has
implemented an adverse price change with respect to its Affinity Merchants
during the Transition Period

                                  ARTICLE  IX

                                INDEMNIFICATION

     9.1  INDEMNIFICATION BY MBNA.  MBNA shall indemnify NOVA and hold NOVA
harmless from any liability, loss, diminution in value, cost, claim, or expense,
including reasonable attorney's and accountant's fees and expenses
(collectively, "NOVA Loss"), incurred by NOVA, its successors or assigns, and
their respective officers, employees, consultants and agents (collectively,
"NOVA Protected Parties"), that result from or arise out of (i) any material
breach or inaccuracy of any representation or warranty of MBNA set forth in this
Agreement, whether such breach or inaccuracy exists or is made as of the Closing
Date or Effective Date which has not been cured within thirty days of receipt of
written notice from NOVA; (ii) the material breach by MBNA of any of its
covenants or agreements contained in this Agreement which has not been cured
within thirty days of receipt of written notice from NOVA; (iii) any liability
or obligation, contingent or otherwise, of MBNA, other than the Assumed
Liabilities; and (iv) violations of law or governmental rules or regulations or
wrongdoing or negligence by MBNA in performing obligations under this Agreement.
A NOVA Protected Party should use commercially reasonable efforts to mitigate
any NOVA Loss hereunder.

     9.2  INDEMNIFICATION BY NOVA.  NOVA shall indemnify MBNA and hold MBNA
harmless from any liability, loss, diminution in value, cost, claim, or expense,
including reasonable attorney's and accountant's fees and expenses
(collectively, "MBNA Loss"), incurred by MBNA, its successors or assigns, and
their respective officers, employees, consultants and agents (collectively,
"MBNA Protected Parties"), that results from or arises out of (i) any material
breach or inaccuracy of any representation or warranty of NOVA set forth in this
Agreement, whether such breach or inaccuracy exists or is made as of the Closing
Date or Effective Date which has not been cured within thirty days of receipt of
written notice from MBNA; (ii) the material breach by NOVA of any of its
covenants or agreements contained in this Agreement which has not been cured
within thirty days of receipt of written notice from MBNA; (iii) any Assumed
Liability; or (iv) material violations of law or governmental rules or
regulations or wrongdoing or negligence by NOVA in performing obligations under
this Agreement.  An MBNA Protected Party should use commercially reasonable
efforts to mitigate any MBNA Loss hereunder.

     9.3  LOSS OR ASSERTED LIABILITY.   Promptly, but in no event later than
thirty (30) days after (a) becoming aware of circumstances that have resulted in
a NOVA Loss or MBNA Loss or potential NOVA Loss or MBNA Loss, whichever is
applicable ("Loss" or "Losses"), for which any party hereto (the "Indemnitee")
intends to seek indemnification under Section 9.1 or Section 9.2, or (b) receipt
by the Indemnitee of written notice of any demand, claim or circumstances which,
with or without the lapse of time, the giving of notice or both, would give rise
to a claim or the commencement (or threatened commencement) of any action,
proceeding or investigation (an "Asserted Liability") that may result in a Loss,
the Indemnitee shall give written notice thereof (the "Claims Notice") to the
other party obligated to provide indemnification pursuant to Section 9.1 or 9.2
(the "Indemnifying Party").  The Claims Notice shall describe the Loss or the
Asserted Liability in reasonable detail and shall indicate the amount
(estimated, if necessary) of the Loss that has been or may be suffered by the
Indemnitee.  The Claims Notice may be amended on one or more occasions with
respect to the amount of the Asserted Liability or the Loss at any time prior to
final resolution of the obligation relating to the Asserted Liability or the
Loss.  Failure of the Indemnitee to give notice pursuant to this Section 9.3
shall not relieve the Indemnifying Party of its obligations to indemnify under
this Article IX.
<PAGE>
 
     9.4   LIMITATIONS.

         (a) With respect to any particular Loss for which an Indemnifying Party
     indemnifies an Indemnitee hereunder, the liability of the Indemnifying
     Party shall be reduced by the amount of any insurance proceeds actually
     received by the Indemnitee as a result of such Loss; provided, however,
     that in no event shall this Section 9.4(a) be construed to require any
     Indemnitee to seek or maintain insurance of any kind.
         (b) Notwithstanding the terms of Section 9.3 hereof, the liability of
     the Indemnifying Party shall be reduced by the incremental amount of the
     Loss, if any, which was caused by the failure of the Indemnitee to give
     notice in the manner set forth in Section 9.3 above.

         (c) No party will be required to indemnify any other party for any Loss
     hereunder attributable to breaches of representations and warranties unless
     the aggregate amount of such Losses with respect to which such party is
     obligated to indemnify exceeds Two Hundred and Fifty Thousand Dollars
     ($250,000) (the "Threshold Amount").  Once the aggregate amount of Losses
     exceeds the Threshold Amount, the party shall be obligated to indemnify for
     all Losses in excess of the Threshold Amount, provided, however, that
     neither party hereto shall not be required to indemnify the other party,
     pursuant to Sections 9.1 or 9.2, as applicable,  for amounts in excess of
     [*].

     9.5   OPPORTUNITY TO CONTEST.  The Indemnifying Party may elect to
compromise or contest, at its own expense and by its own counsel, any Asserted
Liability.  If the Indemnifying Party elects to compromise or contest such
Asserted Liability, it shall within thirty (30) days (or sooner, if the nature
of the Asserted Liability so requires) of the date of the Indemnifying Party's
receipt of the Claims Notice notify the Indemnitee or Indemnitees of its intent
to do so by giving written notice thereof to the Indemnitee (the "Contest
Notice"), and the Indemnitee shall cooperate, at the expense of the Indemnifying
Party, in the compromise or contest of such Asserted Liability.  If the
Indemnifying Party elects not to compromise or contest the Asserted Liability
and fails to notify the Indemnitee of its election as herein provided or
contests its obligation to indemnify under this Agreement, the Indemnitee (upon
further notice to the Indemnifying Party) shall have the right to pay,
compromise or contest such Asserted Liability on behalf of and for the account
and risk of the Indemnifying Party, subject to the right of the Indemnifying
Party to assume the compromise or contest of such Asserted Liability at any time
before final settlement or determination thereof.  Anything in this Article IX
to the contrary notwithstanding, (i) the Indemnitee shall have the right, at its
own cost and expense and for its own account, to compromise or contest any
Asserted Liability, and (ii) the Indemnifying Party shall not, without the
Indemnitees' written consent, settle or compromise any Asserted Liability or
consent to entry of any judgment which does not include an unconditional release
of the Indemnitee from all liability in respect of such Asserted Liability.  In
any event, the Indemnitee and the Indemnifying Party may participate, at their
own expense, in the contest of such Asserted Liability.  If the Indemnifying
Party chooses to contest any Asserted Liability, the Indemnitee shall make
available to the Indemnifying Party any books, records or other documents within
its control that are necessary or appropriate for, shall make its officers and
employees available, on a basis reasonably consistent with their other duties,
in connection with, and shall otherwise cooperate with, such defense.

     9.6  INDEMNITY CLAIMS.

         (a) The representations, warranties, covenants and agreements contained
     herein shall not be extinguished by the Closing but shall survive the
     Closing, subject to the limitations set forth in Section 9.6(b) hereof with
     respect to the time periods within which claims for indemnity must be
     asserted.

         (b)  All claims for indemnification pursuant to this Agreement shall be
     asserted no later than eighteen months after the Transition Date.

     9.7  SUBROGATION.  The Indemnifying Party shall be subrogated to any claims
or rights of the Indemnitee as against other persons with respect to amounts
paid by the Indemnifying Party under this Article IX.  The Indemnitee shall
cooperate with the Indemnifying Party, at the Indemnifying Party's expense, in
the Indemnifying Party's assertion of such claims.


                                  ARTICLE  X

                     MEDIATION AND ARBITRATION OF DISPUTES

     10.1  DISPUTE RESOLUTION.

         (a) In the event of any dispute, claim, question or disagreement
     arising out of or relating to this Agreement or a matter for which a
     dispute resolution mechanism is specifically provided in this Agreement the
     parties shall use reasonable efforts to settle such dispute, claim,
     question or disagreement. To this effect, they shall consult and negotiate
     with each other, in good faith, and, recognizing their mutual interests,
     and attempt to reach a just and equitable solution satisfactory to both
     parties.

         (b) If the parties do not reach such a solution within a period of
     thirty (30) days, then the parties agree first to endeavor in good faith to
     amicably settle their dispute by mediation in accordance with the CPR Model
     Procedure for Mediation of Business Disputes, promulgated by the Center for
     Public Resources, New York City.

         (c) If mediation is unsuccessful within a reasonable time after
     commencement of proceedings as set forth above, but not less than thirty
     (30) days thereafter, the mediator shall so certify and the dispute shall
     be submitted to binding arbitration conducted in accordance with the CPR
     Rules for Non-Administered Arbitration of Business Disputes.  Any
     controversy or dispute shall be arbitrated by a single arbitrator either
     mutually agreed upon by the parties or, absent agreement, appointed in
     accordance with the aforesaid CPR rules.  No mediator under subsection (b),
     above, may serve as an arbitrator.  The arbitration shall be governed by
     the United States Arbitration Act, 9 USC 1-16, and judgment upon the award
     may be entered by any court having jurisdiction thereof.  The arbitrator
     shall have case management authority and shall resolve the controversy in a
     final award within 180 days from commencement of the arbitration action.
     All questions of arbitrability shall be resolved by the arbitrator
     appointed pursuant to this clause.  The prevailing party shall be entitled
     to receive an award of attorney's fees incurred in connection with the
     arbitration and judicial proceedings related thereto.  There shall be no
     appeal from the arbitral award, except for fraud committed by the
     arbitrator(s) in carrying out his duties under the aforesaid rules;
     otherwise the parties irrevocably waive their rights to judicial review of
     any claim or controversy arising out of or related to this Agreement.

         Unless otherwise agreed by MBNA and NOVA, the situs for dispute
            resolution shall be Washington, D.C.

         (e) In the event that the Center for Public Resources no longer
     promulgates rules as set forth above, then the mediation or binding
     arbitration shall be administered under the rules of the American
     Arbitration Association or such other recognized rules for resolution of
     disputes as MBNA and NOVA may mutually agree.

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

                                   OVERVIEW 

The Company's predecessor, NOVA Information Systems, Inc., was formed in
February 1991 to provide sophisticated and cost-effective transaction
processing and related services to predominantly small- to medium-sized
merchants by effectively employing the latest advances in transaction
processing and telecommunications technology.

Since inception, the Company has invested significant capital to develop an
integrated operating platform consisting of hardware, software and network
architecture to process large volumes of card transactions. In addition, the
Company continues to develop the marketing, customer support and managerial
expertise necessary to execute its business strategy. Through the fiscal year
ended February 28, 1995, the Company incurred losses, as the expenditures for
the development of this infrastructure and the cost to convert purchased
portfolios, combined with the cost of providing service, exceeded revenues from
its merchant portfolio. The Company's ongoing expansion of its customer base
resulted in the Company achieving profitability for the first time in the
10-month period ended December 31, 1995.

The Company has increased its customer base through a combination of its own
marketing programs and through a series of merchant portfolio purchases, joint
ventures and alliances that have produced significant additional revenue in
each year since formation. Since its inception in 1991, the Company has
consummated 90 transactions consisting of 84 merchant portfolio purchases,
three operating business acquisitions, two joint ventures and the First Union
Alliance. 

On January 21, 1998, the Company consummated a transaction (the "KeyBank
Joint Venture") with KeyBank National Association ("KeyBank") pursuant to which
the Company will provide transaction processing services to, and jointly own
and operate with KeyBank, a newly created limited liability company called Key
Merchant Services, LLC ("KMS"). The KeyBank Joint Venture, on the basis of
anticipated processed volume, is the largest transaction in the Company's
history as it is expected to add approximately $5.1 billion in annualized
credit and debit card volume to the Company's operating platform. KMS will
market transaction processing services with its own employees throughout the
U.S.A. Further, KeyBank will market and promote, on an exclusive basis,
transaction processing services on behalf of KMS through KeyBank's bank branch
locations. The Company owns a 51% interest in KMS.

On December 30, 1997, the Company consummated a transaction (the "MBNA
Alliance") with MBNA America Bank, N.A. ("MBNA") pursuant to which the Company
purchased substantially all of MBNA's merchant portfolio. MBNA also agreed to
cooperate with the Company in marketing the Company's merchant transaction
processing services and referring exclusively to the Company all merchants,
trade associations, financial institutions, independent sales organizations
("ISOs") and other organizations that request or evidence an interest in
merchant transaction processing services. The Company estimates that the MBNA
portfolio will add approximately $1.0 billion in annualized credit and debit
card transaction processing volume.

Effective October 31, 1997, the Company consummated a transaction (the
"Firstar Joint Venture") with Firstar Bank, U.S.A., N.A. ("Firstar") and
Firstar Bank Milwaukee, N.A., pursuant to which the Company will provide
payment processing services to, and jointly own and operate with Firstar, a
newly created limited liability company called Elan Merchant Services, LLC. In
connection with the Firstar Joint Venture, Firstar and each of the other
banking affiliates of Firstar contributed substantially all of their then
existing bankcard payment processing contracts (representing approximately $3.0
billion in annualized 
<PAGE>
 
credit and debit card volume) to Elan Merchant Services. Further, Firstar will
market and promote, on an exclusive basis, transaction processing services on
behalf of Elan Merchant Services directly and through a network of over 850
correspondent financial institutions. The Company owns a 51% interest in Elan
Merchant Services.

On May 29, 1997, the Company consummated the purchase of the Crestar Bank
merchant portfolio. The Company estimates that the Crestar portfolio will add
approximately $1.8 billion in annualized credit and debit card transaction
processing volume to the Company's network. In addition, NOVA and Crestar Bank
will market and promote, on an exclusive basis, the Company's transaction
processing services through Crestar Bank's approximately 500 branch bank
locations.

The Company expects each of these transactions to provide significant
strategic and financial benefits, including: (i) enhanced distribution channels
to facilitate growth of the Company's processed transaction volume and the
number of merchant locations served; (ii) further geographic diversification of
the Company's portfolio into additional regions of the United States; and (iii)
economies of scale from substantial increases in transaction processing volume
once merchant accounts and other services are fully integrated into the
Company's operating platform.

Historically, the Company 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 recent acquisition activity undertaken by the
Company, the magnitude, scope, timing, duration and expense of the conversion
of the KeyBank Joint Venture, the Firstar Joint Venture and the MBNA portfolio
purchase will, in the aggregate, be greater than any conversion previously
undertaken by the Company. Failure to complete these conversions in accordance
with management plans could have a material adverse effect on the Company's
financial condition and results of operations.

The Company changed its fiscal year end from the last day of February to
December 31, effective December 31, 1995. Accordingly, the following discussion
of results of operations includes a comparison of the year ended December 31,
1997, with the year ended December 31, 1996, and the year ended December 31,
1996, with the 10-month period ended December 31, 1995. 

                      COMPONENTS OF REVENUES AND EXPENSES

                                   Revenues

The Company derives revenues principally from processing credit, charge and
debit card transactions that are authorized and captured through the Company's
proprietary telecommunications network (the "NOVA Network") and through
third-party networks prior to conversion. The Company typically charges
merchants for these card 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 "discount
fees,'' are individually negotiated with each merchant and, in the aggregate,
represented approximately 92.4%, 94.6% and 93.7% of the Company's revenues for
the years ended December 31, 1997 and 1996 and the 10-month period ended
December 31, 1995, respectively. Certain of the Company's merchant customers
are charged a flat fee per transaction, while others are also charged
miscellaneous fees, including fees assessed by the Company for handling
chargebacks, monthly minimums, equipment leases, rentals and sales, and other
miscellaneous services. The Company's revenues are reported net of amounts paid
to ISOs and agent banks under revenue sharing agreements pursuant to which such
parties receive payments based primarily on processing volume for particular
groups of merchants. 
<PAGE>
 
                                   Expenses

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

Conversion costs include costs incurred to convert the acquired portfolios
to the NOVA Network and operating systems. 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, commissions and
benefits, travel and entertainment, telephone, and other operating costs of the
Company's operations and marketing centers and its corporate office.

Depreciation and amortization are related to the Company's capital
expenditures, merchant portfolio purchases and business acquisitions.
Depreciation of property and equipment is recognized on a straight-line basis
over periods of three to seven years for equipment and 30 years for buildings.
Merchant portfolio purchases result in the capitalization of merchant and
customer contract values, which are amortized over 10 years based upon the
Company's merchant attrition experience and projected revenue streams. Excess
cost of businesses acquired is amortized over 30 years. 

                             RESULTS OF OPERATIONS

The following table sets forth for the periods indicated the percentage of
revenues represented by certain items on the Company's consolidated statements

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

                                   Revenues

Revenues increased 26.3% to $335.6 million for the year ended December 31,
1997, compared with $265.8 million for the same period in 1996. The increase
resulted from a 25.6% increase in merchant sales volume processed to $15.0
billion for 1997, compared to $11.9 billion in 1996. Of these increases, $34.0
million in revenues and $1.5 billion in sales volume processed are attributable
to the Firstar Joint Venture and the Crestar portfolio purchase, with the
remainder resulting primarily from internal sales efforts and other bank
marketing relationships. 


                                Cost of Service

Cost of service increased 25.3% to $260.1 million for the year ended
December 31, 1997, compared with $207.6 million for the same period in 1996.
The increase resulted from additional interchange and assessment fees and other
operating costs associated with the higher volume of merchant sales. Cost of
service as a percentage of revenues declined from 78.1% to 77.5%, reflecting
continuing cost efficiencies. These cost efficiencies result from
proportionately lower payments to third-party networks as fewer company
merchants utilize third-party networks and merchant accounting processors, as
well as increased economies of scale.

                               Conversion Costs

Conversion costs decreased 59.4% to $2.6 million for the year ended December
31, 1997, compared with $6.4 million for the same period in 1996. The decrease
resulted primarily from the substantial completion of the conversion of the
First Union Corporation portfolio in 1996. 

                 Selling, General and Administrative Expenses

Selling, general and administrative expenses increased 3.0% to $34.0 million
for the year ended December 31, 1997, compared with $33.0 million for the same
period in 1996. Higher expenses in 1997 resulted from the addition of personnel
in the Company's operations center to support the increased merchant sales
volume processed. Additionally, sales and marketing expenses increased to
support the Company's growing number of merchants and bank marketing
relationships. Selling, general and administrative expenses declined to 10.1%
of revenues for the year ended December 31, 1997, compared with 12.4% for the
same period in 1996, reflecting operational efficiencies.
<PAGE>
 
                         Depreciation and Amortization

Depreciation and amortization increased 52.6% to $10.7 million for the year
ended December 31, 1997, compared with $7.0 million for the same period in
1996. This increase is attributable to increased depreciation from significant
investments in the Company's transaction processing network to expand capacity
and additional amortization from merchant portfolio purchases. 

                               Operating Income

For the foregoing reasons, operating income for the year ended December 31,
1997, increased 138.3% to $28.4 million compared with $11.9 million for the
same period in 1996. 

                        Interest Expense (Income) - Net

Net interest income increased to $721,000 for the year ended December 31, 1997,
compared with $126,000 for the same period in 1996. This increase relates to
lower average bank debt during 1997 than existed during 1996. The Company used
the net proceeds received from the initial public offering in May 1996 to reduce
the bank debt. Further, interest income was generated from the investment of the
remaining net proceeds of the offering and cash flow from operations.

                                 Income Taxes

Income tax expense was recorded at an effective tax rate of 38.6% in fiscal
1997. Income tax expense increased to $10.9 million for the year ended December
31, 1997, compared to $4.8 million for the same period in 1996. This increase
resulted from increased pre-tax income.

                                  Net Income

Net income increased $10.1 million to $17.4 million for the year ended
December 31, 1997, compared with net income of $7.3 million for the same period
in 1996, due to the factors discussed above. 

                   YEAR ENDED DECEMBER 31, 1996 COMPARED TO 
                    10-MONTH PERIOD ENDED DECEMBER 31, 1995

                                   Revenues

Revenues for the year ended December 31, 1996, increased 106.0% to $265.8
million compared with $129.0 million for the 10-month period ended December 31,
1995. The increase resulted primarily from a 99.6 %, or $5.9 billion, increase
in sales volume processed for the year to $11.9 billion from $6.0 billion in
1995.  First Union's merchant processing portfolio, which was acquired effective
December 1, 1995, accounts for increases of $106.7 million in revenues and $4.6
billion in sales volume processed. Due to the Company's change in fiscal year
end, effective as of December 31, 1995, the Company's revenues in 1996 included
a full 12 months, as compared to the prior year's 10- month fiscal year.
Additionally, the Company entered into 17 exclusive bank marketing agreements
in 1996.

                                Cost of Service

NOVA's cost of service increased 106.8% to $207.6 million for the year ended
December 31, 1996, from $100.4 million for the 10-month period ended December
31, 1995. As a percentage of revenues, cost of service increased to 78.1% for
the year ended December 31, 1996, from 77.8% for the 10-month period ended
December 31, 1995. These increases resulted from additional interchange and
assessment fees associated with the higher volume of merchant sales and from
authorization fees paid to third- party networks and merchant accounting
processors for merchants not yet converted to the NOVA Network. 
<PAGE>
 
                               Conversion Costs

Conversion costs increased 85.8% to $6.4 million for the year ended December
31, 1996, as compared with $3.4 million for the 10-month period ended December
31, 1995. The increase resulted primarily from the ongoing conversion of the
First Union portfolio, acquired in December 1995.

                 Selling, General and Administrative Expenses

Selling, general and administrative expenses increased 85.2% to $33.0
million in the year ended December 31, 1996 from $17.8 million for the 10-month
period ended December 31, 1995. Higher expenses in 1996 resulted from
additional staffing levels in the Company's operations center to support the
increased merchant sales volume processed, as well as a one-time cost involved
in consolidating three operational offices around the country to NOVA's
corporate headquarters and the Knoxville, Tennessee center. In addition, sales
and marketing expenses increased to support the Company's growing merchant and
bank alliance relationships. Selling, general and administrative expenses
decreased as a percent of revenues to 12.4% in 1996 from 13.8% in the prior
year, reflecting operating efficiencies. 

                         Depreciation and Amortization

Depreciation and amortization increased 50.6% to $7.0 million for the year ended
December 31, 1996, from $4.6 million for the 10-month period ended December 31,
1995. The increase was principally due to greater depreciation for POS
terminals, additional systems hardware and software purchases to enhance the
Company's transaction processing system, as well as operational equipment needed
to support NOVA's growth. To a lesser extent, this expense increased due to
additional amortization of certain intangible assets related to the merchant
portfolios purchases.

                               Operating Income

For the foregoing reasons, operating income increased 326.9%, or $9.1
million, to $11.9 million for the year ended December 31, 1996, compared to
$2.8 million for the 10-month period ended December 31, 1995. 

                        Interest Expense (Income) - Net

Net interest expense decreased $2.1 million for the year ended December 31,
1996, resulting in net interest income of $126,000, compared to net interest
expense of $2.0 million for the prior year. The decrease in interest expense
was due to reduced levels of bank debt and purchase note obligations resulting
from the use of net proceeds received from the Company's initial public
offering. The increase in interest income was generated from the investment of
the net proceeds received from the Company's initial public offering, as well
as cash generated from operating activities in 1996.

                                 Income Taxes

Income tax expense was recorded at an effective tax rate of 40% in 1996.
During the 10-month period ended December 31, 1995, a one-time tax benefit of
$5.0 million was included in the provision for income tax reflecting the
reversal of a deferred tax valuation allowance as a result of the Company's
improved profitability in 1995.

                                  Net Income

For the year ended December 31, 1996, net income increased $2.4 million, or
48.7%, to $7.3 million compared to $4.9 million for the 10-month period ended
December 31, 1995, due to the factors discussed above. Net income for 1995
included a one-time tax benefit of $5.0 million.

                        LIQUIDITY AND CAPITAL RESOURCES

The Company's primary uses of its capital resources include purchases of
merchant portfolios, capital expenditures and working capital. 

In October 1997, the Company obtained from a third party bank an $80 million
credit facility, the proceeds of which may be used for acquisitions (subject to
certain restrictions) and other corporate purposes. 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 million. As of
December 31, 1997, $32.8 million in borrowings were outstanding under this
facility.

Net cash provided by operating activities was $18.0 million for the year
ended December 31, 1997, as compared to $20.7 million for the year ended
December 31, 1996 and $4.9 million for the 10-month period ended December 31,
1995.

Net cash used in investing activities was $90.6 million for the year ended
December 31, 1997, as compared to $10.0 million for the year ended December 31,
1996 and $5.1 million for the 10-month period ended December 31, 1995. The
Company's investment expenditures primarily consist of merchant portfolio
purchases and investments in computer hardware and software necessary to
support the NOVA Network and the systems at the Company's operations center.
Other significant investment activities include facility expansions necessary
to accommodate the Company's growth. For the years ended December 31, 1997 and
1996, and the 10-month period ended December 31, 1995, the Company's capital
expenditures totaled approximately $15.2 million, $6.1 million and $1.6
million, respectively. For these same periods, merchant processing portfolio
purchases and joint venture investments totaled $75.4 million, $4.0 million and
$3.3 million, respectively.

Net cash provided by financing activities was $33.0 million and $28.9
million for the years ended December 31, 1997 and 1996, respectively. Net cash
provided in 1997 resulted from borrowings under the above credit agreement
which were used for investing activities. Net cash provided in 1996 resulted
primarily from the Company's initial public offering. The proceeds received
from this offering were used to reduce most of its then existing bank debt, to
redeem the 5,000 shares of Series D Preferred Stock for $5.0 million and to pay
all cumulative dividends of $11.7 million to holders of Preferred Stock
concurrent upon the liquidation of all series of Preferred Stock. 

The Company typically has relatively low working capital requirements because
discount fees charged to merchants are collected in an average of 15 days, while
normal payables are paid in 30 days or longer. In addition, increasing
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 the Company. Such
variations are particularly evident at December 31, 1997, in their effect on
trade receivables, which increased 119.1% over 1996, and accounts payable,
including accounts payable to affiliates, which, on a combined basis, increased
80.1% over 1996. Typically, the changes in these working capital accounts would
more closely follow changes in the level of processed volume, which from
December 1996 to December 1997 increased 69.9%. Because of the seasonality of
the Company's business, capital requirements may be greater in certain months.

The Company anticipates that it will incur approximately $20.0 million in
capital expenditures during 1998 for additional operations facilities and for
expansion of the Company's information systems. Such investments relate
directly to the recent portfolio purchases and joint venture investments
described above. The Company anticipates that it will incur substantially lower
capital expenditures in 1999. However, no assurances can be given that the
Company will not incur additional capital expenditures during 1998 and 1999.

The Company must address Year 2000 compliance for POS merchant activity,
internal operating systems and suppliers and vendors. In June of 1997, the
Company was certified by VISA U.S.A. and 
<PAGE>
 
Mastercard International as capable of processing transactions for cards issued
with expiration dates of 2000 and beyond. This means all of the Company's
customers have been upgraded with compliant software, and the Company's network
and switch can accommodate the Year 2000.

The Company has developed a plan to ensure all internal systems are
compliant with the Year 2000. These efforts are well under way and are
scheduled to be completed by year end 1998. Significant outside vendors and
suppliers are also scheduled to be Year 2000 compliant by year end 1998.
However, while the Company believes its planning efforts are adequate to
address its Year 2000 concerns, there can be no guarantee that the systems of
other companies on which the Company's systems and operations rely will be
properly converted on a timely basis and will not have a material effect on the
Company. It is assumed should any vendor not be compliant by January 1, 1999,
the Company will have sufficient time to switch their business to an entity
which is compliant. The cost of Year 2000 initiatives has not been and is not
expected to be material to the Company's results of operations or financial
position.

In February 1998, the Company filed a Registration Statement with the
Securities and Exchange Commission with respect to a proposed public offering
of 7,100,000 shares of Common Stock. Of the shares to be offered, 5,300,000
shares will be sold by the Company and 1,800,000 shares will be sold by certain
selling shareholders. The Company intends to use the proceeds from the offering
to retire indebtedness, to finance potential future acquisitions, to fund
capital expenditures and for general corporate purposes.

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

                  NOTES TO CONSOLIDATED FINANCIAL STATEMENTS 

                                    NOTE 1 

                  Summary of Significant Accounting Policies 

Description of Business and Organization . NOVA Corporation (the "Company'' or
"NOVA'') is an integrated provider of transaction processing services, related
software application products and value-added services primarily to small- to
medium-sized merchants. The Company provides 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. The Company 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. 

NOVA Corporation was incorporated in December 1995. NOVA Information Systems,
Inc., a wholly owned subsidiary and predecessor to the Company ("NOVA
Information Systems''), was incorporated in Georgia in February 1991. Effective
December 1, 1995, the then current shareholders of NOVA Information Systems
contributed to NOVA Corporation all of the shares of capital stock of NOVA
Information Systems owned by them, thereby causing NOVA Information Systems to
become a wholly owned subsidiary of NOVA Corporation .

On October 30, 1995, NOVA entered into an agreement with First Union
Corporation ("First Union") whereby First Union agreed to contribute its
transaction processing assets, including those acquired by First Union through
its acquisition of First Fidelity Bancorporation, to NOVA in exchange for
9,149,209 shares of NOVA's Common Stock. The transaction, which was consummated
on January 31, 1996, is reflected in the accompanying financial statements
since December 1, 1995, because, pursuant to the terms of the agreement,
revenues since December 1, 1995, derived from the First Union assets have
irrevocably accrued to the benefit of NOVA. The transfer of these nonmonetary
assets, primarily terminals at merchant locations, by First Union has been
accounted for at their historical cost of $2,411,000, because First Union is
deemed under the rules and regulations of the Securities and Exchange
Commission to be a promoter of NOVA. 

Principles of Consolidation . The consolidated financial statements include the
accounts of NOVA Corporation and its wholly owned subsidiaries as if NOVA
Corporation existed for all periods presented. Also included in the consolidated
financial statements are the accounts of Elan Merchant Services, LLC, a joint
venture owned 51% by the Company. The operating results from the joint venture
are included from the date the Company purchased its membership interest,
October 31, 1997. All significant intercompany accounts and transactions have
been eliminated in consolidation. The Company has made business and customer
base purchases and has accounted for them as purchase transactions, and,
accordingly, the results of the acquired businesses or customer bases are
included since the dates of purchase.

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.
<PAGE>
 
Revenue and Cost Recognition . Revenues derived from the electronic processing
of transactions (principally merchant discount) are recognized at the time the
merchants' transactions are processed. Related commissions and processing
charges are also recognized at that time.

When the Company purchases merchant portfolios, it generally enters into
revenue sharing agreements with sellers. The revenue sharing amounts are
determined primarily based 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 $8,153,000,
$6,455,000 and $5,446,000, for the years ended December 31, 1997 and 1996 and
the 10-month period ended December 31, 1995, respectively. 

Cost of service includes interchange fees paid to the credit card issuing-
bank, communications costs, VISA and MasterCard assessments, and merchant
accounting processing fees. These costs are recognized at the time the
merchants' transactions are processed and the related revenue is recorded. 

Rental Equipment . The Company rents POS equipment to merchants under month-to-
month agreements. The rented equipment is capitalized and depreciated over three
years. The cost of such equipment and accumulated depreciation at December 31,
1997, and December 31, 1996, included in property and equipment were as follows:

                                        December 31,
                                ---------------------------  
                                    1997            1996
                                ---------------------------
Cost of equipment               $ 6,715,000     $ 5,796,000
Less accumulated depreciation     4,490,000       2,939,000
                                -----------     -----------
                                $ 2,225,000     $ 2,857,000
                                ===========     ===========

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
Company's clearing and settlement banks approximately 15 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 minimizes its risk of loss.
Based on its historical loss experience, the Company has established reserves
for estimated credit losses on transactions processed. 

Stock Compensation . The Company accounts for its stock option plans in
accordance with Accounting Principles Board Opinion Number 25, "Accounting for
Stock Issued to Employees'' ("APB 25''). In accordance with APB 25, no
compensation expense has been recognized because the options had an exercise
price equal to the market value of Common Stock on the day of grant. Refer to
Note 10 regarding pro forma information provided pursuant to Financial
Accounting Standards Board (FASB) Statement No. 123, "Accounting for Stock-Based
Compensation."
<PAGE>
 
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.

Conversion Costs . The cost of converting purchased merchant portfolios from the
seller's processing platform and telecommunications network to the Company's
network is expensed as incurred.

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 30 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. The Company
capitalizes costs associated with the development of software for the Company's
internal use. Such costs are depreciated over the useful life of the software of
up to seven years.

Intangibles . The excess cost of businesses acquired is amortized on the
straight-line basis over 30 years. Accumulated amortization at December 31, 1997
and 1996 was $2,048,000 and $1,552,000, respectively.

Amortization of merchant and customer contracts (portfolios) is provided on
a straight-line basis over a 10-year life, based on the Company's estimates of
future merchant sales volumes. Accumulated amortization of portfolios was
$13,255,000 and $8,174,000 at December 31, 1997 and 1996, respectively. The
Company evaluates the reasonableness of the amortization period for its
portfolios by monitoring the merchant sales volume processed for those
merchants included in the portfolio at the purchase date. The Company will
adjust the amortization period of the portfolios if actual merchant sales
volumes indicate a different amortization period is more appropriate. 

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 related to the
intangible asset over the remaining life of the asset, the carrying value of
the related intangible asset will be reduced to fair value. 

The Company adopted Financial Accounting Standards Board Statement No. 121,
"Accounting for the Impairment of Long-Lived Assets and for Long- Lived Assets
to be Disposed Of'' ("SFAS 121") on January 1, 1996. The adoption of SFAS 121
did not have any effect on the financial statements. 

Income Taxes . The Company accounts for income taxes under the liability method.
Under the liability method, deferred income taxes are recorded to reflect the
net tax effects of temporary differences between the carrying amounts of assets
and liabilities for financial reporting and the amounts used for income tax
purposes.

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

Cash and Cash Equivalents . For purposes of the consolidated statements of cash
flows, the Company considers all highly liquid debt instruments with original
maturities of three months or less to be cash equivalents.
<PAGE>
 
Net Income per Share . In 1997, the Financial Accounting Standards Board issued
Statement No. 128, "Earnings per Share" ("SFAS 128"). SFAS 128 replaced the
calculation of primary and fully diluted earnings per share with basic and
diluted earnings per share. Unlike primary earnings per share, basic earnings
per share excludes any dilutive effects of options, warrants and convertible
securities. Diluted earnings per share is very similar to the previously
reported fully diluted earnings per share. All earnings per share amounts for
all periods have been presented, and, where appropriate, restated to conform to
the SFAS 128 requirements.

                                    NOTE 2

            Merchant Portfolio Purchases and Business Acquisitions 

During the years ended December 31, 1997 and 1996, and the 10-month period
ended December 31, 1995, the Company made purchases from various banks and
third parties, including investments in a joint venture, for an aggregate
purchase price of $75,660,000, $4,095,000 and $3,476,000, respectively. 

Significant 1997 transactions include purchases of the Crestar Bank
("Crestar") merchant portfolio effective May 29, 1997 and the MBNA America
Bank, N.A. ("MBNA") merchant portfolio effective December 31, 1997. The Company
also entered into a joint venture with Firstar Bank, U.S.A., N.A. ("Firstar")
effective October 31, 1997, whereby Firstar and each of the other banking
affiliates of Firstar contributed substantially all merchant portfolio
contracts to the joint venture. The Company owns 51% of the joint venture and
will perform the transaction processing services for the joint venture's
merchant contracts. Estimated annual processing volume for the Crestar, MBNA
and Firstar merchant contracts are $1.8 billion, $1.0 billion and $3.0 billion,
respectively. The Company's operating results reflect each of these purchases
from the effective dates of the transactions.

The following summarizes the allocation of the purchase price to the major
categories of assets acquired and liabilities assumed resulting from the
acquisitions:

                                 Income Taxes

Deferred income taxes reflect the net tax effects of temporary differences
between the carrying amounts of assets and liabilities for financial reporting
purposes and the amount used for income tax purposes. Significant components of
the Company's deferred tax liabilities and assets are as follows:

In the 10-month period ended December 31, 1995, there was a $5,206,000
change in the valuation allowance which resulted in a reduction of the excess
cost of business acquired of $228,000 as a result of deductible temporary
differences acquired in businesses combinations. The remainder of $4,978,000
was included in the provision for income taxes. In assessing the likelihood of
utilization of existing net deferred tax assets, management considered (a) its
current operating environment, (b) results of future operations to generate
sufficient taxable income and (c) the excess of its appreciated asset values
over the related tax basis and, accordingly, has determined that it is more
likely than not that the deferred tax assets will be realized.

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

                                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 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. 

Effective December 1, 1995, all outstanding warrants held by two principal
investors to purchase 1,177,600 shares of Common Stock at prices from $2.34 -
$8.20 per share were exchanged for 557,616 shares of the Company's Common Stock.
The fair value of the shares issued in exchange for the warrants was based upon
the value of the shares inherent in the First Union transaction, which
approximated market value. No compensation or distributions were recorded with
respect to the exchange.

In October 1997, the Company entered into an agreement with a bank for
aggregate loans of up to $80 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 million. On September 30, 2000, all
outstanding borrowings in excess of $50 million 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
million revolving loan commitment are due September 30, 2002.

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. At December 31,
1997, outstanding borrowings included $22.8 million at the bank's base rate of
8.5% and $10.0 million in Eurodollar-based loans at a weighted-average rate of
6.2%. Concurrent with entering the above credit agreement, the Company
cancelled its previous credit facility, which had available borrowings of $10.0
million. There were no borrowings outstanding under the previous facility at
the date of cancellation.

Borrowings under the loan agreement are collateralized by substantially all
the assets of the Company. The loan agreement contains restrictive covenants
which 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.

                              Stock Option Plans 

The Company has elected to follow Accounting Principles Board Opinion No.
25, "Accounting for Stock Issued to Employees" ("APB 25") and related
interpretations in accounting for its employee stock options because, as
discussed below, the alternative fair value accounting provided for under FASB
Statement No. 123, "Accounting for Stock-Based Compensation," requires use of
option valuation models that were not developed for use in valuing employee
stock options. Under APB 25, because the exercise price of the Company's
employee stock options equals the market price of the underlying stock on the
date of grant, no compensation expense is recognized.

Pro forma information regarding net income and earnings per share is
required by Statement 123, which also 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 for 1997: risk-free interest rate of 5.70%; a dividend yield of 0%;
volatility factors of the expected market price of the Company's Common Stock
of 0.544 and a weighted-average expected life of the option of seven years.

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

For purposes of pro forma disclosures, the estimated fair value of the
options is amortized to expense over the options' vesting period. The Company's
pro forma information follows:

                                                         1997           1996
                                                    ---------------------------
Pro forma net income                                $ 16,245,000    $ 6,824,000
Pro forma net income per share                              0.56           0.23
Pro forma net income per share - assuming dilution          0.54           0.23

The effect of applying Statement 123's fair value method to the Company's
stock-based awards granted in 1995 results in net income and earnings per share
that are not materially different from amounts reported because the Company
elected to use the minimum value method allowed under Statement 123 for
non-public companies. Because Statement 123 is applicable only to options
granted subsequent to December 31, 1994, its pro forma effect will not be fully
reflected until 1999.

A description and summary of the Company's stock option plans and activity
follows:

The Company has reserved 3,100,000 common shares related to options and
550,000 shares related to stock appreciation rights, pursuant to its 1991 stock
option and stock appreciation rights plan. The Plan is administered by a
committee of the Board of Directors, which determines the number of shares to
be granted and the option price per share. Each option expires 10 years from
the grant date. The options 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.

A summary of the Company's stock option activity under the 1991 Plan, and
related information, follows:

The Company has reserved 2,000,000 shares of Common Stock for issuance under
the 1996 Employees Stock Incentive Plan related to Incentive Stock Options,
Non-qualified Stock Options, stock appreciation rights and restricted stock
awards. The shares subject to options can be purchased, and rights exercised,
in 25% increments at the end of each of the four years subsequent to the date
of grant. The option price per share for Incentive Stock Options cannot be less
than the fair market value of the Common Stock on the date the option is
granted. Each option expires 10 years after the date of grant.

                             Pro Forma Information

Pro forma net income 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 and $489,000 for the year ended December 31, 1996
and the 10-month period ended December 31, 1995, respectively) and the
weighted-average number of common and common equivalent shares outstanding
during the respective periods, assuming the conversion of Series A, B and C
Convertible Preferred Stock into Common Stock. Dilutive common equivalents
consist of stock options (calculated using the treasury-stock method). Pursuant
to the requirements of the Securities and Exchange Commission, common shares
and common equivalent shares issued at prices below the public offering price
of $19.00 per share during the 10 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 share and per share data, except par value
per share, have been retroactively adjusted to reflect the 2.56-for-one stock
split effected in the form of a stock dividend of the Company's Common Stock,
effective February 1996.

                            Related Party Support 

The Company paid one of its shareholders $2,730,000, $1,817,000 and
$1,220,000 in the years ended December 31, 1997 and 1996 and the 10- month
period ended December 31, 1995, respectively, relating to the Company's
utilization of the shareholder's telecommunications network. 

The Company paid another of its shareholders $2,595,000, $9,532,000 and $943,000
in the years ended December 31, 1997 and 1996 and the 10- month period ended
December 31, 1995, respectively, relating to the Company's utilization of the
shareholder's labor force during conversion, as well as fees paid for certain
transaction processing expenses.

The Company received $850,000 and $1,154,000 of interest income from one of
its shareholders in the years ended December 31, 1997 and 1996, respectively.

                                Retirement Plan

The Company maintains the NOVA Information Systems, Inc. 401(k) and Profit
Sharing Plan (the "Plan''), which covers substantially all eligible employees
of the Company. Under the Plan, the Company may match a percentage of employee
contributions. The Company may also make a profit-sharing contribution to the
Plan on behalf of eligible employees. During the years ended December 31, 1997
and 1996 and the 10-month period ended December 31, 1995, contribution expenses
related to the Plan were not significant. 

                                    NOTE 15

                            Financial Instruments 

The Company's financial instruments at December 31, 1997 and 1996 consist
primarily of cash and cash equivalents and loans payable to a bank. 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 Company's customer base. In addition, the Company performs ongoing credit
evaluations of their customers' financial condition. The Company's cash and
cash equivalents at December 31, 1997, are primarily held at one financial
institution; however, the Company believes the credit risk is limited, due to
the credit standing of the financial institution. In addition, since the
amounts are invested in cash equivalents, there is limited market risk (such as
a reduction in the fair value of investment securities due to rising interest
rates).

The Company has experienced, and expects to continue to experience,
significant seasonality in its business. The Company typically realizes 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. 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.

                               Subsequent Event

Joint Venture") with KeyBank National Association ("KeyBank") pursuant to which
the Company will provide transaction processing services to, and jointly own
and operate with KeyBank, a newly created limited liability company called Key
Merchant Services, LLC ("KMS"). The purchase price of the Company's membership

                        REPORT OF INDEPENDENT AUDITORS 


       To the Board of Directors and Shareholders of NOVA Corporation: 

We have audited the accompanying consolidated balance sheets of NOVA
Corporation as of December 31, 1997 and 1996, and the related consolidated
statements of operations, shareholders' equity and cash flows for the years
ended December 31, 1997 and 1996, and the 10-month period ended December 31,
1995. 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 in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of
material misstatement. An audit includes examining, on a test basis, evidence
supporting the amounts and disclosures in the financial statements. An audit
also includes assessing the accounting principles used and significant
estimates made by management, as well as evaluating the overall financial
statement presentation. We believe that our audits provide a reasonable basis
for our opinion. 

In our opinion, the financial statements referred to above present fairly,
in all material respects, the consolidated financial position of NOVA
Corporation at December 31, 1997 and 1996 and the consolidated results of its
operations and its cash flows for the years ended December 31, 1997 and 1996
and the 10-month period ended December 31, 1995, in conformity with generally
accepted accounting principles.

                     REGARDING FORWARD-LOOKING STATEMENTS

This Annual Report contains certain "forward-looking statements" within the
meaning of Section 27A of the Securities Act of 1933, as amended, which
represent the Company's expectations or beliefs, including, but not limited to,
statements concerning existing and new products and services, technologies and
opportunities, return on investments in products, transaction volume, and the
impact of acquisitions, joint ventures and alliances. When used in the report,
the words "may," "could," "should," "would," "believe," "anticipate,"
"estimate," "expect," "intend," "plan" and similar expressions are intended to
identify forward-looking statements. These statements by their nature involve
substantial risks and uncertainties, certain of which are beyond the Company's
control. The Company cautions that various factors, including the factors
described in the Company's filings with the Securities and Exchange Commission,
as well as general economic conditions and industry trends could cause actual
results or outcomes to differ materially from those expressed in any
forward-looking statements of the Company. Any forward-looking statement speaks
only as of the date of this Annual Report, and the Company undertakes no
obligation to update any forward-looking statement or statements to reflect the
events or circumstances after the date on which such statement is made or to
reflect the occurrence of an unanticipated event. New factors emerge from time
to time, and it is not possible for the Company to predict all of such factors.
Further, the Company cannot assess the impact of each such factor on its
business or the extent to which any factor, or combination of factors, may
cause factor results to differ materially from those contained in any
forward-looking statements.
