ITEM 1.           BUSINESS

GENERAL

Intelligent Systems Corporation, a Georgia corporation (the "Company" or
"Intelligent Systems"), has operated either in corporate or partnership form
since 1973 and its securities have been publicly traded since 1981. The Company
operated as a master limited partnership from 1986 to 1991, when it was merged
into the present corporation (the "Merger"). The Company's executive offices are
located at 4355 Shackleford Road, Norcross, Georgia 30093. The Company's
telephone number is (770) 381-2900.

The Company's operations are involved in two industry segments (which are
defined by the product or service provided rather than the market served):
technology related products and services, and health care services. The
Company's principal majority-owned and controlled operating subsidiaries in the
technology sector include InterQuad Services (training/education for software
products), ChemFree Corporation (bio-remediating parts washers for automotive
and industrial applications), Intelligent Enclosures (mini-environment systems
for ultraclean manufacturing) and HumanSoft LLC (health and human services
software for public health agencies). In the health care services segment, the
Company's operations involve the PsyCare America subsidiary (psychiatric
treatment programs for the Christian community). The Company's operating
subsidiaries are relatively small in size and subject to greater fluctuation in
revenue and profitability than larger, more established businesses would be.

The Company's main focus is to create and manage growing companies through
flexible partnership arrangements. The Company actively explores opportunities,
principally in the technology area, to develop partnerships with promising
domestic companies or to start new businesses. Depending upon the needs of the
partner company, the Company may be the sole, majority or minority owner of the
business and will undertake a variety of roles which often include day-to-day
management of operations, board of director participation, financing, market
planning, strategic contract negotiations, personnel and administrative
functions, etc. Partner companies in which the Company owns less than a majority
interest or in which the Company is not considered the controlling shareholder
are not consolidated in the Company's results of operations, rather they are
accounted for by the equity method. However, the Company may be actively engaged
in managing strategic and operational issues with these companies and devotes
significant resources to the development of the business. In some instances, the
Company may acquire a majority ownership at some future point or the business
may become a stand-alone public company or be sold to another entity. A more
detailed description of some of the Company's affiliated partner companies is
provided on page 7 of this report.

The Company operates the Shared Resource Technology Center, a small business
incubator, at its corporate facility. The Center permits the Company to reduce
its overhead expense by subleasing excess capacity to small businesses that
benefit from flexible, shared resources. At the same time, the Company has
day-to-day contact with emerging companies that may become partnership
companies, either as majority-owned subsidiaries or minority-owned affiliates.
For instance, ChemFree Corporation was started as an incubator company.

The Company expects to continue its regular practice of discussing with
interested parties possible sales, acquisitions or business combinations
involving its operations or related businesses. However, these discussions may
not result in any completed transactions.

For ease of comprehension, the business discussion which follows contains
information on products, markets, competitors, research and development and
manufacturing for various of the Company's operating subsidiaries, organized by
industry sector and by company. For further information concerning the Company's
domestic and foreign operations, see Notes 13 and 14 in the accompanying Notes
to the Consolidated Financial Statements.

INDUSTRY SEGMENT: TECHNOLOGY RELATED PRODUCTS AND SERVICES

HUMANSOFT LLC - HumanSoft LLC (formerly named Public Health Software Systems)
specializes in the design, manufacture and sale of a comprehensive array of
software programs which permit public health agencies to capture, analyze and
manage client information. Within the past 12 months, the Company acquired two
former competitors, QS, Inc. and JK, Inc., to position itself as a leading
provider of information systems software and services for health and human
services organization nationwide. The operations of all companies are
consolidated under the HumanSoft umbrella. HumanSoft products include modules
such as maternal and child health, cancer screening, HIV testing, scheduling,
etc. The acquisition of JK, Inc. in January 1998 expands the HumanSoft offering
to include vital records information systems and health statistics coding and
data collection. The products run on multiple platforms including DOS, Windows,
UNIX, AS/400 and others. Typically, HumanSoft provides some customization and
training services as well as ongoing technical support and, in some cases, data
collection and coding.

HumanSoft customers are local, state and federal public health agencies
nationwide as well as other government agencies, hospitals and clinics.
Installations range from single-site clinics to city-wide and state-wide systems
employing networks of computers. The customer base covers more than 40 states.
HumanSoft sells primarily in response to competitive bids solicited by city,
county and state agencies. The process can take several months and awards are
made on the basis of a number of factors including software features, pricing,
and financial strength. Marketing activities include trade shows and industry
conferences.

HumanSoft competes against a number of other software companies, some of which
are larger and which may have access to greater resources than does HumanSoft.
However, HumanSoft believes it is competitive based on product features, ease of
use and extensive industry experience and contacts in the public health market.
The company continues to add new functionality to its ACCLAIM product and to
develop new versions of its vital records software.

CHEMFREE CORPORATION - ChemFree Corporation (ChemFree) designs, manufactures and
markets the SmartWashertm parts washer which uses an advanced bio-remediation
system to clean automotive and machine parts without using hazardous,
solvent-based chemicals. The SmartWasher consists of a molded plastic tub and
sink with faucet and brush, recirculating pump, heater, electronic control
panel, filter, microorganisms and an aqueous based degreasing solution. Unlike
traditional solvent based systems, there are no regulated, hazardous products
used or produced in the process and the SmartWasher system is completely
self-cleaning. ChemFree sells replacement fluid and filters to its customers
after the parts washer sale.

ChemFree's markets include the automotive, transportation, industrial and
military markets. In the automotive aftermarket sector, customers include
companies with fleets of vehicles to maintain; automobile manufacturers such as
Chrysler, GM and BMW with extensive service networks; and individual and chains
of auto repair shops and auto parts suppliers. Numerous public transport systems
use the SmartWasher in maintenance facilities. The industrial market includes
customers with machinery that requires routine maintenance, such as in the
textile industry. Military applications include vehicle service depots in all
branches of the military. ChemFree entered international markets in 1997 in
England and Korea.

ChemFree's sales activities include both company representatives who sell direct
to high volume customers and several distribution channels: automotive
aftermarket distributors (e.g. NAPA), environment/pollution control equipment
distributors, automobile manufacturers dealer equipment and service
organizations (e.g. GM, Chrysler and BMW) and industrial product distributors.
International markets are served by distributors serving specific countries. The
Company also sells in competitive bid situations, such as military procurements,
and under a GSA schedule to government agencies. Marketing activities include
trade show participation, public and press relations, advertisements in trade
publications, and evaluation programs.

ChemFree competes with larger, established companies using solvent-based systems
which require special handling and hauling of regulated material, other small
companies using non-hazardous systems, and with hazardous waste hauling firms.
Although smaller than the established solvent-based firms, ChemFree believes it
is competitive based on product features, positive environmental impact,
improved health and safety features, elimination of regulatory compliance, and
price.

Research and development at ChemFree is directed toward product extensions,
enhancements of the base unit, fluid and filter and adaptations for specialized
applications. ChemFree subcontracts the manufacturing of major sub-assemblies
built to its specifications to various vendors and performs final assembly and
testing at its own facility. There are multiple sources available for
subassemblies.

INTERQUAD SERVICES - InterQuad Services, with two locations in the London,
England area, provides technical training and skills development programs for
popular microcomputer software and network products. Some of the most popular
offerings are courses for networking products from Novell Inc. and Microsoft
Corporation. InterQuad also provides some consulting services related to
information systems for business.

Current and prospective technical users of personal computers in the UK comprise
the market for education/training activities conducted by InterQuad Services.
Typically, customers choose training programs based on the software and network
products that they have installed or plan to install at their company premises.
InterQuad Services uses extensive advertising, telemarketing and direct mail to
stimulate demand for its products and services.

InterQuad Services competes with a number of similar-sized training/education
companies. It competes on the basis of quality of training staff, comprehensive
and up-to-date course offerings, price and accessibility of training facilities.
With relatively high fixed costs for training staff and facilities,
profitability depends upon the right mix of customers and courses to optimize
the infrastructure.

INTELLIGENT ENCLOSURES - Intelligent Enclosures (iE) is a small subsidiary which
designs, manufactures and markets mini-environments which provide critical
cleanliness, temperature and humidity control in ultra-clean manufacturing
applications such as semiconductor fabrication. Typically, iE's systems surround
robotics tools, providing environmental control at the process tool while
maintaining operator and maintenance access.

The primary market for iE's mini-environment systems is semiconductor
manufacturers. iE has systems installed at sites such as Motorola, Intel, AT&T,
Siemens, IBM and Kodak. Mini-environments are typically used inside traditional
clean-rooms and are installed either in new manufacturing facilities or to
retrofit existing ones.

Mini-environments are typically sold through robotics tool manufacturers,
systems integrators or architectural and engineering firms that incorporate the
iE enclosure as part of a complete manufacturing equipment/process offering. The
sales cycle is usually long and delivery dates may be re-scheduled due to
changes in other vendors' timetables. Typically, iE systems involve considerable
customization and are delivered within two to four months of order placement.

iE competes against traditional clean-room companies and other enclosure
manufacturers that provide a variety of custom and standard products. Certain of
its competitors are larger and more established and may have access to greater
resources than does the company. iE competes based on technical expertise in
air-handling, proprietary product design and superior product features.
Materials are available from a number of sources and iE is not dependent on any
single vendor.

GENERAL - Service for the Company's products varies by product line and is
available in the markets served by the Company either directly by Company
personnel or through its distributors and dealers. The Company provides
warranties of varying length for its products and services and, in some cases,
sells annual technical support programs. The Company's subsidiaries in the
technology segment sell to many customers in numerous markets and would not
experience a material adverse effect if the business of a single customer is
lost.

Intelligent Systems regularly reviews potential hardware and software companies
and products for possible acquisition and/or license. Management expects to
continue this practice.


INDUSTRY SEGMENT: HEALTH CARE SERVICES

PsyCare is an established provider of specialty treatment programs for
individuals with psychiatric and psychological disorders, including depression
and substance abuse. The programs are conducted under PsyCare's Rapha trademark
and are directed toward individuals who prefer a treatment approach that
integrates the patient's physical and psychological needs with their Christian
beliefs. PsyCare provides a continuum of care, including in-patient hospital
programs, partial day programs and intensive group out-patient programs. PsyCare
presently has 14 program sites, including both adult and adolescent in multiple
states.

Hospitals in mid to large size metropolitan areas contract with PsyCare to
conduct a Rapha treatment program in their hospital. PsyCare provides medical
and program directors as well as therapists and maintains control over all
aspects of the treatment, while the hospital provides the physical facility,
administrative services, billing and nursing staff.


                        INTELLIGENT SYSTEMS CORPORATION

                                      -5-
<PAGE>   6
The market for PsyCare's treatment programs includes adults and adolescents
suffering from illnesses such as depression, addiction and behavioral disorders.
The program's integrated approach appeals particularly to individuals affiliated
with churches and other organizations with a Christian basis. Hospitals that
contract with PsyCare to offer the Rapha program do so because it addresses a
segment of the population not typically being served by the hospital.

In the health care services business, the number of patients tends to decline
during the summer months and prior to holidays. In addition, there are a number
of fundamental changes taking place in the industry. In the past few years, the
average length of stay for in-hospital treatment has declined by almost 65
percent. At the same time, managed care payors are exerting pressure to lower
reimbursement rates paid to treatment providers. Furthermore, managed care is
also placing increased emphasis on drug-based treatment programs, with little or
no hospital stay, rather than behavioral modification programs such as those
offered by PsyCare. With the focus of many hospitals on expense reduction,
PsyCare is continually challenged to maintain its margins. The impact of these
trends means that PsyCare must treat many more patients for shorter periods of
stay while keeping strict control over expenses. Although the company opened
programs at new hospitals in 1997, the total number of inpatient programs
declined in 1997 compared to 1996 because of intense pressure by service
providers to restrict hospital stay for mental health treatment, which makes the
Rapha programs less attractive to hospitals. Given these trends, PsyCare has
been reducing overhead and costs and exploring alternatives such as expanding
outpatient programs. However, at this point it is uncertain whether this
strategy will provide a sustainable, profitable business model. In 1996,
approximately 37 percent of Company consolidated revenue was derived from
programs associated with one chain of psychiatric hospitals. This percentage
declined to 13.5 percent in 1997 as the number of programs at the hospital chain
decreased.

Working in local communities and with national associations, PsyCare has
developed an extensive network of Christian churches and organizations by
helping pastors meet the needs of their church members through educational,
outreach and counseling programs. This network will often suggest the Rapha
Treatment program when it has church members in need of professional help since
members feel comfortable that the care is likely to be consistent with their
beliefs. PsyCare also reaches its market through radio broadcast, special
events, conventions, print media, and word-of-mouth referrals from satisfied
patients.

PsyCare's competitors include individual and group practices, private
hospital-affiliated treatment programs, and other independent treatment programs
with a religious component. With the advent of managed care and the restrictions
on in-hospital treatment, PsyCare also competes with outpatient programs and
drug-based therapies. PsyCare believes it is one of the top Christian programs
in the country but fundamental changes in the industry brought about by managed
care are affecting the success of PsyCare and other similar programs. Unlike
many of its competitors, PsyCare does not own hospitals or clinics but rather
contracts with other facilities to provide the Rapha program in their hospital.
This strategy reduces PsyCare's fixed costs but makes it somewhat dependent upon
decisions made by the hospital over which PsyCare has little control. For
instance, a change in a hospital's management or priorities may result in
cancellation of a contract and require PsyCare to relocate to another hospital.
Among PsyCare's strengths is the strong programmatic basis for its treatment
that ensures that treatment received in each location is of consistent content
and quality and not dependent on the characteristics of a particular therapist.
Another key factor is PsyCare's strong network of Christian organizations that
support the program's focus.

PATENTS, TRADEMARKS AND TRADE SECRETS

The Company has several patents (both issued and pending) covering certain
aspects of its products and processes. It may be possible for competitors to
duplicate certain aspects of the Company's products and processes even though
the Company regards such aspects as proprietary. The Company has registered with
the US Patent and Trademark Office and various foreign jurisdictions numerous
trademarks and service marks for its products. The Company believes that an
active trademark and copyright protection program is important in developing and
maintaining brand recognition and protecting its intellectual property. The
Company markets its products under trademarks and service marks such as Rapha,
iEAir, ACCLAIM, SmartWasher, OzzyJuice and others.

PERSONNEL

As of February 28, 1998, the Company had 249 full-time equivalent employees. The
Company's employees are not represented by a labor union and the Company has not
had any work stoppages or strikes. The Company believes that its employee
relations are good.

AFFILIATED PARTNER COMPANIES

From time to time, Intelligent Systems evaluates products or companies that it
believes are involved in promising technologies or markets with good growth
potential. From time to time, it has acquired or invested in such products,
product rights or companies and expects to continue to do so as a regular part
of its strategy. The Company holds investment positions in various growth stage
companies, most of which are in technology-related fields and privately held.
Some examples of the Company's involvement are as follows:

- -        A significant equity position in PaySys International, Inc. (PaySys), a
         leading software company involved in payment processing software
         systems. Although the Company owns 58 percent of the currently issued
         and outstanding shares of PaySys common stock, it does not consolidate
         the results of operations of PaySys because the Company's majority
         ownership is temporary. PaySys filed a registration statement on Form
         S-1 in the fall of 1997 related to an initial public offering of its
         common stock but the registration is not yet effective. If the
         registration becomes effective or PaySys sells equity in a private
         sale, the Company's ownership would likely decrease to below 50
         percent.

- -        A 34 percent equity position in Visibility, Inc., a privately held
         software company involved in engineer-to-order software for large
         customers selling and managing complex products.

- -        A 3.4 percent equity position in IQ Software Corporation (IQ), a
         software company in which the Company has been involved since 1987,
         which completed its initial public offering in 1992.

- -        A 23.5 percent equity position in Paragon Interface, a privately held
         company involved in data mapping and translation software targeted
         initially for the insurance industry.

- -        A 35 percent equity position in Risk Laboratories, a privately held
         software company involved in risk management software for corporate
         risk departments.


ITEM 2.           PROPERTIES

At December 31, 1997, to house its manufacturing, sales, service and
administration operations, the Company had leases covering approximately 147,525
square feet in two facilities in Atlanta, GA; 6,101 square feet in Greenville,
SC; 7,000 square feet in Denver, CO; and 14,506 square feet in the London,
England area. The Company believes that its leased facilities are adequate for
its existing and foreseeable business operations. A portion of the headquarters
facility is subleased to businesses in the small business incubator.


ITEM 3.           LEGAL PROCEEDINGS

The Company is a party to a small number of legal matters arising in the
ordinary course of its business. It is management's opinion that none of these
matters will have a material adverse impact on the Company's consolidated
financial position or results of operations.


ITEM 4.           SUBMISSION OF MATTERS TO A VOTE OF SECURITY HOLDERS

No matter was submitted by the Company to a vote of its shareholders during the
fiscal quarter ended December 31, 1997.

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

Effective July 1, 1997, the Company acquired QS, Inc. ("QS") and has included
the results of QS in the consolidated operating results since that date. In
December 1995, the Company sold its Intelligent Systems Japan ("ISJ") subsidiary
and in September 1996 sold the assets of a small health care subsidiary. Results
of operations of these businesses are not included in the consolidated results
of operations after the respective sale dates. A significant amount of the
variance in operating results between 1995 and 1996 can be attributed to the
sale of ISJ in 1995.

RESULTS OF OPERATIONS

Net sales are derived from two major areas: technology-related products and
services and health care services. Principal operating subsidiaries in the
technology segment include InterQuad Services (software training programs),
ChemFree Corporation (bio-remediating parts washers), Intelligent Enclosures
(mini-environment systems for ultraclean manufacturing) and HumanSoft LLC, which
includes QS operations (health and human services software for public health
agencies). The operating subsidiary in the health care segment is PsyCare
America (specialty psychiatric treatment programs).

SALES - Net sales in 1997 were $21,160,000 compared to $23,678,000 in 1996.
Although each of the technology sector companies experienced revenue increases
ranging from 11 percent to almost 100 percent, the 11 percent decline overall is
attributed to a decrease of more than 45 percent in revenue derived from the
PsyCare operations. PsyCare had fewer inpatient programs in 1997 than in 1996
and the contract reimbursement rates were lower in 1997 than in 1996. In the
technology sector, the companies sold a greater volume of products and services
in 1997 than in 1996. The Company also benefited from the acquisition of QS part
way through 1997.

Net sales in 1996 were $23,678,000 compared to $28,240,000 in 1995. The 16
percent decline year-to-year is principally related to the disposition of
certain businesses during 1996 and 1995. Revenue from the ongoing companies was
essentially flat year-to-year with a net increase in revenue from the technology
companies and a slight decline in PsyCare revenue. Revenue increases in the
technology sector were led by InterQuad and HumanSoft based on a greater volume
of services and products sold, offset in part by a decline in revenue at the
ChemFree subsidiary due in large part to stock balancing and a product upgrade
program which offset current revenue. The slight decline year-to-year in health
care service revenue reflects a fourth quarter reduction in the number of
inpatient programs.

Health care services represent 29 percent, 55 percent and 50 percent of revenue
in 1997, 1996 and 1995, respectively. The sharp decline in the contribution of
the health care services is due to fewer inpatient programs at the PsyCare
subsidiary as well as the sale in September 1996 of another health care
subsidiary. Revenue derived from international sales was 33 percent in 1997,
compared to 25 percent in 1996 and 32 percent in 1995. The increase in 1997 was
due to higher sales volume at the InterQuad subsidiary, the first international
sales of ChemFree products in the UK and Korea and the decrease in PsyCare's
revenues, which are all domestic. The year-to-year decline in 1996 is due to the
sale of ISJ in 1995.

COST OF SALES - Cost of sales in 1997 was 62 percent of revenue compared to 54
percent of revenue in 1996. Cost of sales differs for each of the Company's
subsidiaries, ranging in 1997 from 50 to 70 percent of revenue. The overall
increase in cost of sales as a percentage of revenue relates primarily to higher
cost of services at the InterQuad subsidiary due to increased use of higher paid
consultants to conduct training classes for part of the year as a result of a
shortage of qualified employees. In addition, PsyCare experienced lower average
rates on contract reimbursement for inpatient programs.

Cost of sales in 1996 was 54 percent of revenue compared to 52 percent in 1995.
The change is principally related to the fact that ISJ's cost for software
products was significantly lower than the cost for products and services
provided by the remaining subsidiaries, thus contributing to a lower overall
cost of sales in 1995. After eliminating the effect of ISJ, for the remaining
operations, there was a decline in cost of sales as a percent of revenue in the
health care service segment due to operating efficiencies and lower personnel
costs and a slight increase in cost of sales for the technology companies
reflecting price pressure due to competition.

OPERATING EXPENSES - In 1997, marketing and general and administrative expenses
declined by approximately 17 percent and 4 percent, respectively, compared to
1996 on an 11 percent decline in revenue. PsyCare reduced its marketing expenses
significantly in line with lower revenue levels, while increases at certain
technology subsidiaries were tied to generating and supporting higher sales
volumes. General and administrative expenses declined in absolute values
year-to-year but increased 


                        INTELLIGENT SYSTEMS CORPORATION

                                      -9-
<PAGE>   10
slightly as a percentage of revenue in 1997 compared to 1996. The acquisition of
QS increased overhead expenses in the second half of the year. Research and
development expense in 1997 was $1.5 million in 1997 compared to $286,000 in
1996. The difference is due principally to a non-recurring charge of $953,000
booked in the third quarter of 1997 related to the allocation of a portion of
the QS purchase price to in-process research and development. The remaining
increase is due to more spending on new product development at the HumanSoft
operation.

Expenses for marketing, general and administrative and research and development
activities were lower by $3,228,000 in 1996 than in 1995. These expenses
declined by 20 percent year-to-year on a 16 percent decline in revenue. After
eliminating the expense and revenue of ISJ, expenses at the comparable remaining
subsidiaries represented 55 percent of revenue in 1996, a significant
improvement compared to 70 percent of revenue in 1995. The improvement in the
expense to revenue ratio results from improved operating efficiency at the
PsyCare operation through consolidation of functions and programs, as well as
controlling expenses while growing revenues at the other subsidiaries, except
for ChemFree. At ChemFree, expenses increased to provide the infrastructure to
support the existing installed base of products, to expand the marketing and
sales efforts to develop new channels of distribution and target markets, and to
add new product enhancements. In 1996, PsyCare incurred a non-recurring expense
of $250,000 in the second quarter to buy out a long-term contract and amend a
license agreement.

INTEREST INCOME - Net interest income in 1997 was $350,000, 30 percent lower
than in 1996. The decrease relates to higher interest expense in 1997 as well as
a reduction in interest bearing notes receivable. Net interest income in 1996
increased by $73,000 over 1995 due in part to lower interest expense in 1996
because the Company repaid its outstanding bank debt in 1996.

INVESTMENT INCOME - In 1997, the Company recorded a net loss of $2,585,000 on
investments compared to investment income of $5,844,000 in 1996. In 1997, the
principal components of this category include a gain of $1.9 million on the sale
of PaySys stock (see Note 3), a gain of $469,000 on the sale of an investment in
Astra Communications, a gain of $217,000 on the sale of OrCAD stock (see Note
3), a $3.0 million write-off of a note receivable from DayStar Digital, Inc.
(see Note 5) and $2.3 million in net losses in the equity of investments
accounted for by the equity method. In 1996, the Company recorded gains of $6.6
million on aggregate sales of 315,000 shares of common stock of IQ Software
Corporation (IQ) from time to time during the year. The Company also recorded a
gain, net of taxes, of $337,000 on the sale of 104,484 shares of OrCAD, Inc.
common stock in OrCAD's initial public offering (see Note 3). In the fourth
quarter of 1996, the Company recorded a charge of $1.0 million to reduce the
carrying value of its minority equity investment in DayStar. In 1995, the
Company recorded a gain of $818,000 on the sale of a portion of its holdings in
IQ and a gain of $1.3 million on the exchange of the Company's equity interest
in ISJ for OrCAD, Inc. common stock. In addition, in 1995 the Company recorded a
loss of $203,000 related to its equity in the losses of PaySys.

OTHER INCOME - Other income/expense in 1997 and 1996 consists mainly of several
miscellaneous, non-recurring sources of income and expense. In 1995, the Company
recognized income from marketing and consulting agreements related to the sale
of a subsidiary in 1991. The agreements terminated in 1995 and thus no related
income was recorded in later years.

TAXES - Taxes payable in 1997 relate to the operations of QS. The Company used
net loss carryforwards to offset taxable income in 1996. Income taxes in 1995
are related to the income of ISJ prior to its sale in December 1995 as well as a
partial reversal of a tax refund at a subsidiary upon completion of final tax
returns for a prior period.

COMMON SHARES - The Company has repurchased its common shares in each of the
last three years under a stock repurchase program. The repurchases resulted in
5,104,467, 5,126,767 and 5,312,867 shares outstanding at December 31, 1997, 1996
and 1995, respectively.

ACCOUNTING CHANGES - In October 1995, the Financial Accounting Standards Board
issued Statement No. 123, "Accounting for Stock-Based Compensation". The
Statement requires companies to estimate the value of all stock-based
compensation using a recognized pricing model. Companies have the option of
recognizing this value as an expense or disclosing its pro forma effects on net
income. The Company adopted the disclosure requirements of this statement and
has chosen to continue to apply the accounting provision of Accounting Principle
Board Opinion No. 25. As a result, the adoption of this new standard did not
have an effect on the Company's financial position or results of operations.

Effective January 1996, 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," which established accounting standards for


                        INTELLIGENT SYSTEMS CORPORATION

                                      -10-
<PAGE>   11
the impairment of long-lived assets, certain identifiable intangibles and
goodwill related to those assets to be held and used, as well as for long-lived
assets and certain identifiable intangibles to be disposed of. The adoption of
this standard did not have a material effect on the Company's financial
position.

Effective December 31, 1997, the Company adopted SFAS No. 128, "Earnings Per
Share", which changes the method of computing earnings per share. The new
standard requires presentation of "basic earnings per share" and "diluted
earnings per share", as defined. Basic and diluted earnings per share amounts
pursuant to SFAS No. 128 do not differ from reported earnings per share amounts
under existing accounting rules.

In October 1997, the AICPA issued Statement of Position 97-2, "Software Revenue
Recognition". SOP 97-2 clarifies and changes some software recognition practices
and supersedes the existing guidance of SOP 91-1. SOP 97-2 must be adopted
effective January 1, 1998. The Company's management does not believe adopting
SOP 97-2 will have a material impact on the Company's financial position or
results of operations.

LIQUIDITY AND CAPITAL RESOURCES

In 1997, the principal sources of liquidity were $2.0 million from the sale of
PaySys shares (see Note 3), $1.7 million from the sale of investments in OrCAD
and Astra Communications, advances totaling approximately $700,000 under bank
lines of credit, advances under short-term notes totaling $778,000, the maturity
of certificates of deposit totaling $1.1 million and approximately $1.0 million
generated from operations. The principal uses of funds were $870,000 to fund the
acquisition of QS, Inc. (see Note 2), $4.6 million to acquire a 34 percent
equity position in Visibility, Inc. (a privately held software company), $1.7
million to increase the Company's long-term investments in several small,
privately-held technology companies, $1.2 million in net advances under loans to
companies in which the Company holds long-term investments and $1.2 million to
acquire property and equipment mainly related to new facilities at the InterQuad
subsidiary. Notes payable and long-term debt at December 31, 1997 are comprised
of $700,000 in bank debt, $1.5 million in notes payable to the sellers of QS,
and $778,000 in notes related to two acquisitions of long-term investments.

In 1996, the principal sources of liquidity were $7,193,000 from the proceeds of
various sales of IQ stock, $1,069,000 from the proceeds of the sale of OrCAD
common stock and repayment of a note receivable of $400,000. The principal uses
of funds were to increase the Company's long-term investments as a minority
investor in several promising, privately-held companies, to repay $1,488,000 of
bank debt, to repurchase 236,100 shares of the Company's common stock during the
year for $619,000, to purchase approximately $1.4 million in fixed assets
(mainly computers and related equipment), to purchase certificates of deposit
totaling $1,056,000, and to fund working capital requirements of domestic
operations.

In October 1997, PaySys filed a registration statement on Form S-1 with respect
to a proposed initial public offering of its common stock, in which the Company
had anticipated selling some of its PaySys stock to provide additional
liquidity. As of the date hereof, the registration has not become effective.
Although the Company believes that PaySys will be successful in raising capital
in 1998 either through a public offering or private sale, there can be no
assurance as to the timing or amount of capital raised or to what extent the
Company would participate in the sale of PaySys stock. Consequently, subsequent
to the year-end, the Company arranged for an additional bank loan of up to
$1,000,000 secured by the Company's holdings in PaySys common stock which the
Company believes will be adequate to fund its operations and commitments in the
foreseeable future. The Company will not make new investments while the bank
loan is outstanding without the bank's permission. The Company believes it could
enter into a private sale of some portion of its PaySys holdings, at a
significant gain, if it desired to do so prior to an effective public offering
of PaySys common stock.

The Company believes it has adequate access to capital through bank borrowings
or sale of assets to support current operations and plans. As explained in Note
1 to the Consolidated Financial Statements, a substantial deterioration in the
financial condition of any of the companies in which the Company has significant
long-term investments could have an adverse effect on the Company.

                    REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS


TO THE STOCKHOLDERS OF INTELLIGENT SYSTEMS CORPORATION:

We have audited the accompanying consolidated balance sheets of Intelligent
Systems Corporation (a Georgia corporation) and its subsidiary companies and
operating partnerships as of December 31, 1997 and 1996, and the related
consolidated statements of operations, changes in stockholders' equity, and cash
flows for each of the three years in the period ended December 31, 1997. These
financial statements and the schedule referred to below are the responsibility
of the Company's management. Our responsibility is to express an opinion on
these financial statements and schedule based on our audits. We did not audit
the financial statements of InterQuad Services Limited, a majority-owned
subsidiary, which statements reflect total assets and total revenues of 18.9
percent and 31.2 percent, respectively, in 1997 and of 9.4 percent and 25.1
percent, respectively, in 1996 of the consolidated totals. We did not audit the
financial statements of PaySys International, Inc., an investment which is
reflected in the accompanying financial statements using the equity method of
accounting. The investment in PaySys International, Inc. represents 0 percent of
total assets in 1997 and 6.9 percent of total assets in 1996, and the equity in
its 1997 net loss and its 1996 net income represents, respectively, 40 percent
of consolidated net loss for 1997 and 1.1 percent of consolidated net income for
1996. The statements of InterQuad Services Limited and PaySys International,
Inc. were audited by other auditors whose reports have been furnished to us and
our opinion, insofar as it relates to the amounts included for InterQuad
Services Limited and PaySys International, Inc., is based solely on the reports
of the other auditors.

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

In our opinion, based on our audit and the reports of the other auditors, the
financial statements referred to above present fairly, in all material respects,
the financial position of Intelligent Systems Corporation and its subsidiary
companies and operating partnerships as of December 31, 1997 and 1996, and the
results of their operations and their cash flows for each of the three years in
the period ended December 31, 1997 in conformity with generally accepted
accounting principles.

Our audits were made for the purpose of forming an opinion on the basic
financial statements taken as a whole. The supplemental schedule II in Item
14(a)(2) is presented for purposes of complying with the Securities and Exchange
Commission's rules and is not part of the basic financial statements. This
schedule has been subjected to the auditing procedures applied in the audit of
the basic financial statements and, in our opinion, fairly states in all
material respects the financial data required to be set forth therein in
relation to the basic financial statements taken as a whole.

NOTE 1


ORGANIZATION AND SUMMARY OF
SIGNIFICANT ACCOUNTING POLICIES

Organization - Intelligent Systems Corporation, a Georgia corporation (the
"Corporation" or the "Company"), was formed in November 1991 to acquire through
merger the business, net assets and operations of Intelligent Systems Master,
L.P.

Nature of Operations - The Company is involved in creating and managing
businesses through flexible partnership arrangements. Consolidated partnership
companies (in which the Company has the majority ownership and control) are
principally engaged in two industries: technology related products and services
and health care services (as defined more specifically in Note 14). The
Company's affiliate partnership companies (in which the Company has a minority
ownership or non-controlling stake) are mainly involved in the technology
industry.

Use of Estimates - The preparation of financial statements in conformity with
generally accepted accounting principles requires management to make estimates
and assumptions that affect the reported amounts of assets and liabilities and
disclosure of contingent assets and liabilities at the date of the financial
statements and the reported amounts of revenues and expenses during the
reporting period. Actual results could differ from those estimates.

Consolidation - The financial statements include the accounts of Intelligent
Systems Corporation and its majority owned and controlled U.S. and non-U.S.
subsidiary companies after elimination of material intercompany accounts and
transactions.

Investments - Investments in entities in which the Company has a 20 to 50
percent ownership interest or where majority ownership is temporary are
accounted for by the equity method. Investments of less than 20 percent in
non-marketable equity securities are accounted for at the lower of cost or
market. Marketable securities are accounted for in accordance with Statement of
Financial Accounting Standards No. 115, "Accounting for Certain Investments in
Debt and Equity Securities" (SFAS No. 115). The aggregate fair value of the
Company's available-for-sale securities, which consist primarily of 157,801
shares of IQ Software Corporation (IQ) common stock as of December 31, 1997 and
1996 and 104,484 shares of common stock of OrCAD, Inc. (OrCAD) as of December
31, 1996, totaled $1,288,000 and $4,818,000, at December 31, 1997 and 1996,
respectively. Such amounts include unrealized holding gains of $836,000 and
$3,804,000, as of December 31, 1997 and 1996, respectively, which are reflected
as a separate component of stockholders' equity. In 1997, the Company recorded a
gain of $217,000 and cash proceeds of $948,000 from the sale of 104,484 shares
of common stock of OrCAD as well as a gain of $1,865,000 and cash proceeds of
$2.0 million on the sale of 50,537 shares of common stock of PaySys
International, Inc. (Note 3). In 1996, the Company recorded gains of $6,628,000
and cash proceeds of $7,193,000 on sales of 315,000 shares of IQ common stock as
well as a gain of $337,000 and cash proceeds of $1,069,000 on the sale of
104,484 shares of common stock of OrCAD. The gains on the transactions are
calculated based on the average cost basis of the securities. The Company's
short-term investments are classified as trading securities under SFAS No. 115.
The impact on the December 31, 1997 and 1996 financial statements of applying
SFAS No. 115 to the trading securities was immaterial. Approximately $6.6
million of the Company's long-term investments at December 31, 1997 are
concentrated in IQ and Visibility, Inc. (see Note 4). A deterioration in the
financial condition of either of these companies could have an adverse effect on
the Company's financial condition.

Translation of Foreign Currencies - The Company considers that local currencies
are the functional currencies for foreign operations. Assets and liabilities are
translated to U.S. dollars at year-end exchange rates. Income and expense items
are translated at average rates of exchange prevailing during the year.
Translation adjustments are accumulated as a separate component of stockholders'
equity. Gains and losses which result from foreign currency transactions are
included in earnings.

Inventories - Inventories are stated at the lower of average cost or market.
Cost includes labor, materials and production overhead. Market is defined as net
realizable value.

Property and Equipment - Property and equipment are carried at cost. For
financial reporting purposes, depreciation is provided using the 150 percent
declining balance method over the estimated lives of the assets, as follows:

<TABLE>

CLASSIFICATION                       USEFUL LIFE IN YEARS

 Leasehold improvements                       1-7
- --------------------------------------------------------------
</TABLE>

Accumulated depreciation and amortization was $4,386,000 and $3,162,000 at
December 31, 1997 and 1996, respectively.

Intangibles - Intangibles are carried at cost net of related amortization. The
excess of costs over underlying net assets of businesses acquired is generally
amortized over periods of three to five years using the straight-line method.
Accumulated amortization of intangibles totaled $1.8 million and $1.2 million at
December 31, 1997 and 1996, respectively. The Company follows a policy of
writing off the asset and accumulated amortization for fully amortized
intangibles. The Company periodically reviews the values

assigned to intangible assets to determine whether they have been permanently
impaired. Relative to goodwill, the Company uses an estimate of the undiscounted
cash flows of the applicable entity over the remaining life of the goodwill in
measuring whether the goodwill is recoverable. Based on this analysis, the
Company wrote off $367,000 of goodwill related to Carisys, Inc. in 1995. This
write-off is reflected in general and administrative expense in the accompanying
statements of operations. In 1997, 1996 and 1995, the Company recorded
intangible amortization expense of approximately $604,000, $332,000 and
$773,000, respectively. In 1997, the Company expensed $953,000 of purchased
research and development related to the acquisition of QS, Inc. as more fully
discussed in Note 2. This expense is included in research and development
expense on the accompanying statements of operations.

The Company conforms to the requirements of SFAS No. 86, "Accounting for the
Costs of Computer Software to be Sold, Leased or Otherwise Marketed", which
requires capitalization of costs incurred in developing new software once
technological feasibility, as defined, has been reached. Costs of maintaining
existing software and research and development are expensed as incurred. The
Company did not capitalize any software development costs during the years ended
December 31, 1997, 1996 and 1995.

Accrued Expenses and Other Current Liabilities - Accrued expenses and other
liabilities at December 31, 1997 and 1996 consist of the following:

- ---------------------------------------------------------------
</TABLE>

Warranty Costs - Estimated costs associated with product warranties are accrued
as an expense in the period the related sales are recognized.

Revenue Recognition - Revenue is derived from sales of software licenses,
technology-related products and services and health care services. The Company
recognizes revenue when products are shipped or, in the case of service
providers, when the services are rendered. Revenue recognition practices for
software are in accordance with Statement of Position 91-1, "Software Revenue
Recognition". The Company generally recognizes software license revenue upon
delivery of the software and related documentation when there are no significant
remaining obligations. The Company accrues the costs of insignificant
obligations remaining when software license revenue is recognized. Service fees
received from the sale of software maintenance and support contracts provide
customers access to technical support and minor upgrades to licensed revenues
and are recognized as services are provided over the life of such contracts. The
Company provides for estimated sales returns in the period in which the sales
are recorded.

Cost of Sales - Cost of sales includes direct material, direct labor and
production overhead for product companies and direct cost of services rendered
for service companies.

Accounting Changes - Effective December 31, 1997, the Company adopted SFAS No.
128, "Earnings Per Share", which changes the method of computing earnings per
share. The new standard requires presentation of "basic earnings per share" and
"diluted earnings per share", as defined. Basic and diluted earnings per share
amounts pursuant to SFAS No. 128 do not differ from reported earnings per share
amounts under existing accounting rules.

In October 1995, the Financial Accounting Standards Board issued Statement No.
123, "Accounting for Stock-Based Compensation". The Statement requires companies
to estimate the value of all stock-based compensation using a recognized pricing
model. Companies have the option of recognizing this value as an expense or
disclosing its pro forma effects on net income. The Company has adopted the
disclosure requirements of this statement and has chosen to continue to apply
the accounting provision of Accounting Principle Board Opinion No. 25. As a
result, the adoption of this new standard did not have an effect on the
Company's financial position or results of operations. See Note 11.

Effective January 1996, 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," which established accounting standards for
the impairment of long-lived assets, certain identifiable intangibles and
goodwill related to those assets to be held and used, as well as for long-lived
assets and certain identifiable intangibles to be disposed of. The adoption of
this standard did not have a material effect on the Company's financial
position.

In June 1997, the Financial Accounting Standards Board issued Statement No. 130,
"Reporting Comprehensive Income". The Statement requires companies to report
comprehensive income and its components in its financial statements.
Comprehensive income is the total of net income and all other nonowner changes
in equity in a period. The Company will adopt the disclosure requirements of
this statement in March 1998.

In June 1997, the Financial Accounting Standards Board issued Statement No. 131,
"Disclosures about Segments of an Enterprise and Related Information". The
Statement requires a management approach to be used when reporting business
segments. Reportable segments are based on products and services, geography,
legal structure or management structure. The Company will adopt the disclosure
requirements of this statement in March 1998.

<PAGE>   24
In October 1997, the AICPA issued Statement of Position 97-2, "Software Revenue
Recognition". SOP 97-2 clarifies and changes some software recognition practices
and supersedes the existing guidance of SOP 91-1. SOP 97-2 must be adopted
effective January 1, 1998. The Company's management does not believe adopting
SOP 97-2 will have a material impact on the Company's financial position or
results of operations.


NOTE 2

ACQUISITIONS

Carisys, Inc. - Effective February 8, 1995, the Company acquired a controlling
interest in Carisys, a start-up engaged in the manufacture and sale of carrier
tape products. The Company had previously held a minority ownership position in
Carisys. The Company paid $100,000 in cash for its equity interest and exercised
an existing warrant for no additional consideration. The acquisition was
accounted for as a purchase. Since the date of acquisition, the Company has
consolidated the results of operations of Carisys without recording a minority
interest, since there are no other contributing investors. The Company wrote off
$367,000 of goodwill related to Carisys in the fourth quarter of 1995 and the
business wound down its operations in early 1996 due to unexpected losses and
market changes.

QS, Inc. - Effective July 1, 1997, the Company acquired all of the outstanding
common stock of QS, Inc. (QS), a company engaged in providing software products
and services to the public health market. The Company paid $2.0 million in cash
and issued a promissory note for $1.5 million due in three equal annual
installments beginning July 1, 1998 and bearing interest at 8.5 percent per
annum, payable quarterly. The promissory note is guaranteed by an executive
officer of the Company. The acquisition was accounted for as a purchase. The
Company expensed $953,000 of purchased research and development projects that
had not reached technological feasibility and that did not have an alternative
future use. Since the acquisition date, the Company has consolidated the results
of operations of QS.


NOTE 3

SALE OF ASSETS

PaySys International, Inc. - On March 31, 1997, the Company sold 50,537 (252,685
post-split) shares of common stock of PaySys International, Inc. ("PaySys") in a
private transaction. The Company received $2.0 million in cash for the stock and
recorded a gain of $1,864,000 on the sale. The Company retains 4,135,330
post-split shares of common stock of PaySys as of December 31, 1997. 

Intelligent Systems Japan, K. K. - Effective December 2, 1995, the Company sold
all its ownership interest in Intelligent Systems Japan (ISJ), a subsidiary
company, to OrCAD, Inc. The Company exchanged its interest in ISJ for 208,968
shares of common stock of OrCAD. The Company recorded a gain of $1.3 million in
the quarter ended December 31, 1995 on the exchange transaction. On March 1,
1996, OrCAD completed its initial public offering. The Company sold one-half of
its OrCAD stock (104,484 shares) in the initial public offering and recognized a
gain, net of tax, of $337,000 in the first quarter of 1996. The Company sold its
remaining 104,484 shares of common stock of OrCAD in the second quarter of 1997,
recognizing a gain of $217,000 on the sale.


NOTE 4

INVESTMENTS IN AFFILIATES

At December 31, 1997, the Company owned a 58 percent interest in PaySys. Since
it is the majority owner only temporarily, the Company is not considered the
controlling shareholder in 1997 and therefore, the investment is classified as
an affiliate and accounted for by the equity method of accounting. The Company's
pro rata share of PaySys losses was $7.9 million in 1997. However, in accordance
with the equity method of accounting, the Company only recorded $3.0 million,
reducing the Company's investment of $3.0 million to zero. The Company has no
obligation or intent to provide additional funding to PaySys. No dividends were
received from the affiliate during 1997 and 1996.

The table below contains the summarized financial information of PaySys.

ACCOUNTS AND NOTES RECEIVABLE AND OTHER COMMITMENTS

At December 31, 1997 and 1996, the Company's allowance for doubtful accounts and
sales returns amounted to $207,000 and $372,000, respectively.

Provisions for doubtful accounts and sales returns were $46,000, $312,000 and
$446,000 for the years ended December 31, 1997, 1996 and 1995, respectively.

The Company holds minority ownership positions in Paragon Interface, Inc. (data
mapping software) and Risk Laboratories, Inc. (risk management software). As
part of these transactions, the Company entered into loan agreements with terms
of two to three years and interest rates ranging from 2 to 5 percent over prime.
The Company provided advances under these commitments (which amount to
approximately $368,000 and $150,000 at December 31, 1997 and 1996, respectively)
and has no commitment for additional funding under the terms of the agreements.
At December 31, 1997, the Company owns 23.5 percent and 35 percent of the equity
in Paragon and Risk, respectively, and accounts for these investments by the
equity method.

In April 1995, the Company entered into a Pledge Agreement with IQ Software
Corporation (IQ) pursuant to which the Company pledged 240,163 shares of IQ
stock held by the Company as collateral for a loan of $1.8 million from IQ to
DayStar Digital Inc. In 1996, IQ released 85,259 shares of stock held as
collateral that was then sold by the Company. In 1997, the Company repaid the
$1.8 million debt of DayStar to IQ and IQ released the balance of 154,904 shares
to the Company. The Company subsequently wrote off $3.0 million related to
uncollectability of the note from DayStar when DayStar ceased operations in
October 1997.

A reconciliation between the Company's effective tax rate and the U.S. statutory
rate is not provided since only state income and foreign taxes are provided.

At December 31, 1997, the Company's domestic subsidiaries had net operating loss
carryforwards totaling $19.0 million. The net operating loss carryforwards, if
unused as offsets to future taxable income, will expire beginning in 2005 and


                        INTELLIGENT SYSTEMS CORPORATION

                                      F-10
<PAGE>   26
continuing through 2012. The utilization of these carry-forwards may be limited
in some cases to taxable income of the particular subsidiary and also may be
subject to annual limitation under the Internal Revenue Code in connection with
a greater than 50 percent change in ownership as defined under Section 382.

The Company accounts for income taxes using Statement of Financial Accounting
Standard 109, "Accounting for Income Taxes". The Company has a deferred tax
benefit of approximately $10.0 million and $8.6 million at December 31, 1997 and
1996, respectively. As the Company's ability to realize the deferred tax asset
is uncertain, the amount is offset in both 1997 and 1996 by a valuation
allowance of an equal amount. The deferred tax benefit at December 31, 1997 and
1996 relates primarily to net operating loss carryforwards.

Income taxes paid during 1997, 1996 and 1995 amounted to $16,000, $3,000 and $0,
respectively.

NOTE 11

STOCK OPTION PLAN

The Company instituted the 1991 Incentive Stock Plan (the "Plan") in December
1991, which was amended in 1997 to increase the number of shares authorized
under the Plan to 925,000. The Plan provides shares of common stock that may be
sold to officers and key employees. Stock options are granted at fair market
value on the date of grant. As of December 31, 1997, 655,000 options are fully
vested and exercisable at a weighted average price per share of $1.75. Of the
unvested options, 5,000 vest in 1998 and 5,000 vest in 1999. All options expire
ten years from their respective dates of grant. At December 31, 1997, the
weighted average remaining contractual life of the outstanding options is 6.8
years and there are 655,000 options exercisable with option prices ranging from
$0.875 to $2.94 and with a weighted average price per share of $1.75. Stock

The Company accounts for the Plan under the provisions of APB No. 25. The
following pro forma information is based on estimating the fair value of grants
under the Plan based upon the provisions of SFAS No. 123. The fair value of each
option granted in 1995 and 1996 has been estimated as of the date of grant using
the Black-Scholes option pricing model with the following weighted average
assumptions: risk free interest rate of 6.3 percent, expected life of the option
of 6

years, expected dividend yield rate of 0 percent, and expected volatility of 63
percent. Under these assumptions, the weighted average fair value of options
granted in 1996 was $1.54. There were no awards under the Plan in 1997. The fair
value of the grants would be amortized over the vesting period for the options.
Accordingly, the Company's pro forma net income (loss) and net income (loss) per
common share assuming compensation cost was determined under SFAS No. 123 would
have been the following:

Because SFAS No. 123 method of accounting has not been applied to grants and
awards prior to January 1, 1995, the resulting pro forma compensation cost may
not be representative of that expected in future years.


NOTE 12

STOCKHOLDERS' EQUITY

The Corporation has authorized 20,000,000 shares of Common Stock, $.01 par value
per share, and 2,000,000 shares of Series A Preferred Stock, $.10 par value per
share. No shares of Preferred Stock have been issued; however, the Company
adopted a Rights Agreement on November 25, 1997, which provides that, under
certain circumstances, shareholders may redeem the Rights to purchase shares of
Preferred Stock. The Rights have certain anti-takeover effects. The Board of
Directors has authorized stock repurchases at various times in the past. The
Company repurchased and retired 47,300 and 236,100 shares of common stock in the
years ended December 31, 1997 and 1996, respectively.


NOTE 13

FOREIGN SALES
AND OPERATIONS

Aggregate export and foreign sales from continuing operations were approximately
$7.0 million, $5.9 million and $9.0 million for the years ended December 31,
1997, 1996 and 1995, respectively. Export and foreign sales were made
principally in the United Kingdom and the Far East. Sales in these geographic
areas are as follows:

For the years ended December 31, 1997, 1996 and 1995, income (loss) before
provision for income taxes derived from foreign subsidiaries approximated
$(930,000), $43,000 and $130,000, respectively.

As of December 31, 1997 and 1996, foreign subsidiaries had assets of $3.6
million and $2.3 million, respectively, and total liabilities of $4.0 million
and $2.3 million, respectively.

Foreign subsidiaries are located in England and there are no currency exchange
restrictions that would affect the Company's financial position or results of
operations.

The accounting for translation of non-US currency amounts is discussed in Note
1.


NOTE 14

INDUSTRY SEGMENTS

The Company's operating divisions are principally involved in two industry
segments: health care services and technology related products and services.
Operations in health care services involve mental health and substance abuse
treatment programs and, through August 1996, locum tenens service (placement of
physicians in temporary positions). The Company derived 13.5 percent, 37 percent
and 27 percent of its consolidated revenue in 1997, 1996 and 1995, respectively,
from a national chain of hospitals in which the Company conducts some of its
treatment programs. In the fourth quarter of 1996 and during 1997, several
programs located in the chain's hospitals were closed. The Company has in the
past and is likely in the future to contract with other hospitals or chains to
conduct its programs. Operations in technology related products and services
include design, development and marketing of microcomputer software; educational
training programs for PC users; design, manufacture and sales of
mini-environments for semiconductor manufacturing; and manufacture and sales of
bio-remediating parts washers.

Total revenue by industry includes sales to unaffiliated customers. Intersegment
sales are not material. Operating profit is total revenue less operating
expenses. None of the general corporate overhead expense has been allocated to
the individual industry segments. Identifiable assets by industry are those
assets that are used in the Company's operations in each industry. Corporate
assets are principally cash, marketable securities, notes receivable and
investments.

NOTE 16

SUBSEQUENT EVENTS

Effective January 1, 1998, the Company acquired all the common stock of JK, Inc.
(JK), a company that provides software and services to the public health market.
The purchase price included $200,000 cash, a promissory note of $600,000 and 645
units of limited liability interest (approximately 14 percent) of the Company's
HumanSoft LLC subsidiary. The note is due in three equal annual installments
beginning January 1, 1999 and bears interest of 8.5 percent per annum payable
quarterly. The sellers may exchange a portion of the note for additional equity
of HumanSoft prior to January 1, 1999. Additional contingent payments of up to
$500,000 may be due the sellers based on attainment of performance criteria in
1998. The acquisition was accounted for as a purchase.

On February 17, 1998, the Company entered into a loan agreement with a
commercial bank providing for borrowings up to $1.0 million. The loan is secured
by 4,014,872 shares of PaySys common stock held by the Company and bears
interest at prime plus 3.5 percent per annum.

                                Auditors' Report
         to the Stockholders and directors of InterQuad Services Limited


We have audited the balance sheet at 31 December 1997 and the profit and loss
account for the year then ended of InterQuad Services Limited which have been
prepared under the historical cost convention and the company's accounting
policies.

Respective responsibilities of directors and auditors

This company's directors are responsible for the preparation of financial
statements. It is our responsibility to form an independent opinion, based on
our audit, on those statements and to report our opinion to you.

Basis of opinion

We conducted our audit in accordance with Auditing Standards issued by the
Auditing Practices Board. The results of our audit would not have been
materially different had the audit been conducted in accordance with U.S.
generally accepted auditing standards. An audit includes examination, on a test
basis, of evidence relevant to the amounts and disclosures in the financial
statements. It also includes an assessment of the significant estimates and
judgements made by the directors in the preparation of the financial statements,
and of whether the accounting policies are appropriate to the company's
circumstances, consistently applied and adequately disclosed.

We planned and performed our audit so as to obtain all the information and
explanations which we considered necessary in order to provide us with
sufficient evidence to give reasonable assurance that the financial statements
are free from material misstatement, whether caused by fraud or other
irregularity or error. In forming our opinion we also evaluated the overall
adequacy of the presentation of information in the financial statements.

Opinion

In our opinion, the financial statements referred to above present fairly, in
all material respects, the financial position of InterQuad Services Limited as
at 31 December 1997 and the results of its operations for the year then ended.
The financial statements conform with UK generally accepted accounting
principles.

In our opinion, the financial statements would not be materially different if
prepared under U.S. generally accepted accounting principles.

                         Report of Independent Auditors


Board of Directors
PaySys International, Inc.

We have audited the accompanying consolidated balance sheets of PaySys
International, Inc. and subsidiaries as of December 31, 1996 and 1997, and the
related consolidated statements of operations, shareholders' equity, and cash
flows for each of the three years in the period ended December 31, 1997. These
consolidated 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 consolidated financial statements referred to above present
fairly, in all material respects, the consolidated financial position of PaySys
International, Inc. and subsidiaries at December 31, 1996 and 1997 and the
consolidated results of their operations and their cash flows for each of the
three years in the period ended December 31, 1997, in conformity with generally
accepted accounting principles.

As discussed in Note 1 to the consolidated financial statements, effective
October 1, 1997 the Company adopted Statement of Position 97-2, "Software
Revenue Recognition", changing its method of recognizing revenue on software
transactions.

                   Notes to Consolidated Financial Statements


1. BUSINESS AND SIGNIFICANT ACCOUNTING POLICIES

BUSINESS

PaySys International, Inc. (the Company) was incorporated on January 27, 1981.
The Company develops, licenses and supports computer software for use by
financial institutions, retailers and third party processors to process credit
card transactions. The consolidated financial statements include the accounts of
the Company and its wholly-owned subsidiaries. All significant intercompany
balances, transactions, and profits and losses have been eliminated.

USE OF ESTIMATES

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

REVENUE RECOGNITION

Revenues are derived from sales of software licenses and related services.

Through September 30, 1997, the Company's revenue recognition policies were in
accordance with Statement of Position (SOP) 91-1, "Software Revenue
Recognition". Under the provisions of SOP 91-1, the Company generally recognized
software license revenue upon delivery of the software and related documentation
when there were no significant remaining obligations and collectibility was
assessed as probable. Service fees received from the sales of software
maintenance and support contracts and sales of other professional services were
recognized over the period the services were provided or as the services were
performed.

Adoption of the new revenue recognition policies of SOP 97-2, "Software Revenue
Recognition", is required for all transactions beginning January 1, 1998, but
earlier adoption is encouraged for periods not previously reported. Prior
periods reported under SOP 91-1 may not be restated.

1. SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)

REVENUE RECOGNITION (CONTINUED)

The Company elected to adopt the provisions of SOP 97-2 effective October 1,
1997. The most significant impact of adopting SOP 97-2 on the Company's revenue
recognition policies is later recognition of revenue on certain contracts than
under past practices. Under SOP 97-2, license and professional service fee
revenues from contracts which require significant production or modification are
recognized under contract accounting on a percentage of completion basis as
services are performed. For contracts which do not require significant
production or modification, fees are allocated to the various contract elements
based on the fair value of each element and are recognized as follows: software
license revenue upon delivery of the software and related documentation when
collectibility is assessed as probable; professional services revenue as the
services are performed; and postcontract customer support over the term of the
arrangement. Revenue related to research and development agreements is
recognized as services are performed over the related funding period for each
contract. Such revenue is included in license revenue.

CONCENTRATION OF CREDIT RISK AND SIGNIFICANT CUSTOMERS

The Company's revenues consist primarily of license and service revenues from
large companies in the United States, Canada, South America, Australia, New
Zealand, and South Africa. The Company does not obtain collateral against its
outstanding receivables. The Company maintains reserves for potential credit
losses for both billed and unbilled receivables. Bad debt expense was $121,000,
$133,000 and $680,000 during the years ended 1995, 1996 and 1997, respectively.
During 1997, one customer accounted for 19% of revenues; during 1996, one
customer accounted for 11% of revenues; during 1995, two customers accounted for
15% and 13% of revenues.

CASH AND CASH EQUIVALENTS

The Company considers all highly liquid investments with maturities of three
months or less when purchased to be cash equivalents. The Company maintains
deposits with a bank and invests its excess cash in overnight funds which bear
minimal risk.

1. SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)

FURNITURE AND EQUIPMENT

Furniture and equipment are carried at cost less accumulated depreciation.
Depreciation is computed using straight-line method over the estimated useful
lives (generally 3 to 5 years). Amortization of computer equipment under capital
lease is recorded over the term of the lease and is included in depreciation
expense. Expenditures for repairs and maintenance are charged to operations as
incurred.

COMPUTER SOFTWARE COSTS

The Company conforms with the requirements of Statement of Financial Accounting
Standards (SFAS) No. 86, "Accounting for the Costs of Computer Software to Be
Sold, Leased or Otherwise Marketed", which requires capitalization of costs
incurred in developing new software products once technological feasibility, as
defined, has been reached. Costs of maintaining existing software and research
and development are expensed as incurred. The Company capitalized software
development costs of $2,343,000, $1,132,000, and $210,000 during the years ended
1995, 1996, and 1997, respectively. The Company records amortization of software
development costs capitalized in an amount equal to the greater of the amount
computed using i) the ratio that current gross revenues for a product bear to
the total of current and anticipated revenues for that product or ii) the
straight-line method over the estimated useful life of the released product
(currently three years). Amortization of internally-developed software costs
totaled $3,247,000, $1,168,000 and $2,257,000 for the years ended December 31,
1995, 1996 and 1997, respectively. The higher amortization of capitalized
software costs for 1995 and 1997 is due to the write-off of $2.1 million and
$949,000, respectively, of capitalized software costs for projects deemed to
have no net realizable value.

INCOME TAXES

The Company follows the liability method of accounting for income taxes.
Deferred income taxes relate to the net tax effects of temporary differences
between the carrying amounts of assets and liabilities for financial reporting
purposes and the amounts used for income tax purposes.

STOCK-BASED COMPENSATION

In October 1995, the FASB issued SFAS No. 123, "Accounting for Stock-Based
Compensation", which provides an alternative to Accounting Principles Board
Opinion No. 25, "Accounting for Stock Issued to Employees" (APB 25), in
accounting for stock-based compensation issued to employees. As permitted by
SFAS No. 123, the Company continues to account for stock option grants in
accordance with APB 25 and has elected the pro forma disclosure alternative of
the effect of SFAS No. 123. Accordingly, adoption of the standard in 1996 did
not affect the Companies' results of operations.

POSTPONED STOCK OFFERING

In December 1997, the Company postponed for more than ninety days a planned
public offering of its common stock. Costs associated with the postponed
offering were expensed during 1997.

RECLASSIFICATION

Certain amounts reported in the 1995 and 1996 financial statements have been
reclassified to conform to the 1997 financial statement presentation.

3. FAIR VALUE OF FINANCIAL INSTRUMENTS

The Company considers its cash and cash equivalents, accounts receivable, line
of credit and long-term debt and capital lease obligations to be its only
significant financial instruments and believes that the carrying amounts of
these instruments approximates their fair value. The carrying amount of
long-term debt approximates fair value based on current interest rates available
to the Company for debt instruments with similar terms, degree of risk and
remaining maturities. The remaining financial instruments approximate fair value
based on the short-term nature of these instruments.

Income tax expense for the year ended December 31, 1997 relates to an increase
in the valuation allowance to reduce the net deferred tax asset balance to zero
and current foreign withholding taxes payable. No additional income tax expense
has been recorded for the year ended December 31, 1997 due to the Company's loss
for the period and the federal tax credit carryforward position from prior
periods.

At December 31, 1997, the Company had general business, foreign tax and AMT
credit carryforwards which expire in 1998 through 2012 available to offset
future federal income tax liabilities totalling approximately $1,900,000. In
addition, the Company has approximately $7,300,000 of net operating losses for
federal income tax purposes at

December 31, 1997, which may be carried forward through 2012. The tax benefits
of these credit carryforwards can be realized only through their application to
taxable income arising from future successful operations of the Company. These
credit and net operating loss carryforwards may be subject to certain
limitations under Section 382 in the event of an ownership change. Due to the
uncertainty of the Company's ability to fully realize the benefits of the credit
carryforwards, a valuation allowance has been recorded against net deferred tax
assets. When recognized, the tax benefit of those items will be applied to
reduce future income tax amounts.

The Company's foreign subsidiaries had cumulative losses of $4,477,000 at
December 31, 1997 which have been fully reserved by a valuation allowance.

7. SHAREHOLDERS' EQUITY

COMMON STOCK

In October 1997 the Company's Board of Directors approved a five-for-one stock
split effected as a stock dividend. Accordingly, all the share data has been
retroactively adjusted to reflect these changes.

Effective August 1, 1995, the Company issued 1,552,010 shares of common stock to
ISC for the cancellation of $900,000 in line of credit borrowings, $83,000 in
accrued interest and $259,000 in accounts payable to a subsidiary of ISC.

WARRANTS

Pursuant to a 1992 loan agreement between the Company and Sirrom Capital, L.P.
(Sirrom), Sirrom obtained warrants to purchase 150,000 shares of the Company's
common stock at an exercise price of $.002 per share. The warrants were
exercised in August of 1997.

WARRANTS (CONTINUED)

Pursuant to a loan agreement dated January 24, 1994 between the Company and ISC,
ISC received a warrant to purchase 277,605 shares of the Company's common stock
at $.002 per share in consideration for making the loan. The warrant was
exercised in August 1997.

In connection with a financing agreement entered into with Sirrom on September
26, 1997, the Company issued a warrant to purchase 37,660 shares of the
Company's common stock at an exercise price of $.002 per share which is fully
exercisable and outstanding at December 31, 1997. The warrants were valued at
approximately $300,000. If the debt remains outstanding for certain periods
during the term of the financing arrangement the Company will be required to
grant additional shares under the warrant.

STOCK-BASED AWARDS TO EMPLOYEES

The Company has elected to follow APB 25 and related interpretations in
accounting for its stock-based awards to employees because, as discussed below,
the alternative fair value accounting provided for under SFAS No. 123 requires
use of option valuation models that were not developed for use in valuing
stock-based awards to employees. Under APB 25, no compensation expense is
recognized for stock-based awards with an exercise price equal to the fair value
of the underlying stock on the date of grant.

Proforma information regarding net income (loss) is required by SFAS No. 123,
which also requires that the information be determined as if the Company has
accounted for its stock-based awards to employees granted subsequent to December
31, 1994 under the fair value method prescribed by that statement. The fair
value for these awards were estimated at the date of grant using the minimum
value method with the following weighted-average assumptions for 1996 and 1997:
risk-free interest rate of 6%; dividend yields of 0%; and a weighted-average
expected life of the awards of 8 years, 8 years and 4 years, respectively. The
weighted average fair value of awards during 1995, 1996 and 1997 was $.26, $.26
and $.66 per share, respectively.

STOCK-BASED AWARDS TO EMPLOYEES (CONTINUED)

The option valuation models require the input of highly subjective assumptions.
Because the Company's stock-based awards to employees have characteristics
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 awards.

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

Because SFAS No. 123 is applicable only to awards subsequent to December 31,
1994, its pro forma effect will not be fully reflected until 1999.

The 1995 Stock Incentive Plan (the "1995 Plan") allows for the granting of
options for up to 1,088,750 shares of common stock to employees and directors.
Stock options granted under the Plan may be either incentive stock options or
nonqualified stock options. Incentive stock options may be granted with exercise
prices of no less than the fair market value. The options expire 10 years from
the date of grant. Options may be granted with different vesting terms but
generally provide for vesting equally over a four year period.

In October 1997, the Company adopted the 1997 Stock Incentive Plan (the "1997
Plan"). The 1997 Plan allows for the granting of options for up to 411,250
shares of common stock to employees, non-employee directors, consultants and
other vendors.

Options outstanding at $.80 per share totaled 827,250 of which 523,490 were
exercisable at December 31, 1997. The weighted average remaining contractual
life of options exercisable at $.80 per share was 8.0 years at September 30,
1997. Options exercisable at $3.10 per share totaled 230,835 of which 60,355

contractual life of options exercisable at $3.10 per share was 9.0 years at

In addition to the stock option plans described above, the Company has issued
warrants to purchase common stock to employees. During 1995, the Company issued
to each of two individuals warrants to purchase 52,675 shares of common stock at
an exercise price of $.60 per share. These warrants, which expire in December
2005, become exercisable equally over a two year and three year vesting period.
In April and June 1997, 35,000 shares of common stock were issued pursuant to
the partial exercise of one of these warrants and the remainder of the warrant
to purchase 17,675 shares of common stock was canceled in September, 1997.

Additionally, during 1996 the Company issued warrants to two employees to
purchase 1,104,110 shares of common stock exercisable at a price per share based
on $50,000,000 divided by the number of shares outstanding at the exercise date.
These warrants were exercisable upon achievement of certain milestones and
expire in February 2003. Effective August 5, 1997, the Company amended these
warrants. The amendment fixed the exercise price of the warrants at $4.80 per
share, and the warrants became fully exercisable as of the amendment date. In
addition, the amendment added provisions (i) restricting transfer of any shares
obtained from exercise of the warrants until the earlier of achievement of
certain milestones or February 2003 and (ii) withholding certain registration
rights until achievement of the milestones. As a result of amending the
warrants, the Company recorded compensation expense of $3,708,000 in 1997 for
the difference between the exercise price and estimated fair value per share at
the amendment date.

At December 31, 1997, a total of 3,105,695 shares of the Company's common stock
were reserved for the exercise of outstanding stock warrants and options.

                      REPRESENTATIONS AND WARRANTIES OF ISC


         In order to meet the requirements of the Shareholders, ISC hereby
represents and warrants, as of the date hereof and as of the Closing Date as

         V.1   Organization, Power and Authority of ISC.

<PAGE>   25
               (b) The execution, delivery and performance of this Agreement,
the Notes and the Escrow Agreement and the consummation of the transactions
contemplated hereby, have been duly and validly authorized by all necessary
action, corporate or otherwise, on the part of ISC. This Agreement, the Notes
and the Escrow Agreement constitute ISC's legal, valid, and binding obligations,
enforceable in accordance with their terms.

               (c) ISC has obtained all necessary consents, approvals,
authorizations or estoppels of any other Person or governmental or regulatory
authority required to be obtained to authorize and permit ISC to purchase all of
the Shares. The execution and delivery of this Agreement, the Notes and the
Escrow Agreement, and the consummation of the transactions contemplated herein
by ISC, and the performance of the covenants and agreements will not, with or
without the giving of notice or the lapse of time, or both, (i) violate or
conflict with any of the provisions of any Articles of Incorporation or Bylaws
of ISC; (ii) violate, conflict with or result in a material breach or default
under or cause termination of any material term or condition of any material
mortgage, indenture, contract, license, permit, instrument, trust document, or
other agreement, document or instrument to which ISC is a party or by which ISC
or any of its properties may be bound; or (iii) violate any Rule. ISC has the
right, power and capacity to execute, deliver and perform this Agreement, the
Notes and the Escrow Agreement and to consummate the transactions contemplated
hereby.

         5.2   Financial Statements. The financial statements contained in ISC's
Form 10-K for the period ending December 31, 1996, and its Form 10-Q for the
period ending March 31, 1997, (both of which are attached hereto) fairly present
the financial position of ISC as of the dates thereof and the results of its
operations for the respective periods thereof. Since March 31, 1997, there has
been no material adverse change in the financial condition of ISC or its
business, operations or assets.

                                   ARTICLE VI

                            COVENANTS OF THE PARTIES

         VI.1  Cooperation. Shareholders and ISC shall cooperate fully with each
other and their respective employees, legal counsel, accountants and other
representatives and advisers in 


                                       24
<PAGE>   26
connection with the steps required to be taken as part of their respective
obligations under this Agreement; and shall, at any time and from time to time
after the Closing, upon the reasonable request of the other, do, execute,
acknowledge and deliver, or will cause to be done, executed, acknowledged and
delivered, all such further acts, deeds, assignments, transfers, conveyances,

         VI.2  Records. Except as provided in the Employment Letter between
Francis Crowder and ISC dated April 14, 1997, Shareholders shall provide to QS,

QS Business.

         VI.3  Use of QS Name. The Shareholders shall cease to use the name "QS"
(or any variation thereof) for any business purpose, except as employees or
agents of QS or ISC, and for the benefit of QS, ISC or their Affiliates.

         VI.4  Expenses. Whether or not the expenses are incurred before or 
after the Closing, each of the expenses incurred by ISC, QS and Shareholders in
connection with the authorization, preparation, execution and performance of
this Agreement, including without limitation all fees, commissions, and expenses
of agents, representatives, counsel, accountants, brokers and finders, shall be
paid by the party that incurred such expenses. Without limiting the generality
of the foregoing, Shareholders shall be responsible for the payment of: any
fees, commissions or expenses of any broker or finder engaged by QS or
Shareholders and any expenses of QS.

         VI.5  Tax Matters.

               (a) Shareholders shall pay all Taxes arising from or relating to
the sale of the Shares to ISC.

               (b) ISC and QS shall file and control any returns required to be

               (c) Shareholders, on the one hand, and ISC, on the other hand,
agree to give prompt notice to each other of any 


                                       25
<PAGE>   27
proposed adjustment to Taxes for periods ending on or prior to the Closing Date.
Shareholders and ISC shall cooperate with each other in the conduct of any Tax
audit or other proceedings involving QS for such periods. In connection with any
such audit or other proceeding ISC, upon the Shareholders' request, shall
provide the Shareholders copies of all notices, correspondence, demands,
assessments and other documents generated in connection with such audit or other
proceeding, all of which information shall remain subject to Section 7.13
(Confidentiality) below. The Shareholders shall also have the right to discuss
the status of such audit or other proceeding with the ISC's representatives and,
with the prior written consent of ISC (not to be unreasonably withheld), with
the applicable taxing authorities involved. All of such activities by the
Shareholders shall be conducted in a manner so as not to adversely impact the
best interests of QS.

               (d) Shareholders on the one hand, and ISC, on the other hand,
agree to furnish or cause to be furnished to each other, upon request, as
promptly as practicable, such information and assistance (including access to
books and records) relating to QS as is reasonably necessary for the preparation
of any return, claim for refund or audit, and the prosecution or defense of any
claim, suit or proceeding relating to any proposed adjustment.

         VI.6  Survival of Warranties. The Warranties will not merge, but will
survive the Closing as follows:

               (a) the Warranties contained in Sections 3.2, 3.4, 4.6 and 4.13
hereof will survive the Closing indefinitely; and

               (b) all Warranties not identified in Section 6.6(a) above shall
survive the Closing for a period of three (3) years after the Closing Date.

         VI.7  Indemnification.

               (a) By the Shareholders. Shareholders jointly (except as provided
in subsection 6.7(b)(5) hereof) and severally shall indemnify, reimburse and
hold harmless ISC, its Affiliates and any successor or assigns (the "Indemnified
Persons") for any and all direct or indirect claims, losses, liabilities,
damages (including special and consequential damages), costs (including court
costs) and expenses (including all attorneys' and accountants' fees and
expenses) (hereinafter "a Loss" or "Losses"), as a result of or in connection
with (i) any breach, inaccuracy or untruth of any Warranty; or (ii) any breach
of or noncompliance by any Shareholder with any covenant or agreement of
Shareholder contained in this Agreement or in any other agreement or instrument
delivered in connection with this Agreement ; or (iii) any litigation, mediation
or arbitration involving QS, any Shareholder, or QS Business arising from
actions taken or facts existing before the Closing or arising out of or related
to the transactions contemplated by this Agreement; or (iv) any act or omission
of QS or any Shareholder constituting or causing non-compliance on or after the
date hereof with any requirement of applicable Rules, if such act or omission
occurred or arose prior to the Closing; or (v) any fees, commissions or expenses
of any broker or finder engaged by QS or Shareholders; or (vi) any Taxes for
which there was an insufficient accrual shown on the Financial Statements or
Interim Financial Statements.

               (b) Limitations.

               (1) Shareholders shall not be required to indemnify an
Indemnified Person with respect to any Loss unless the Loss, when aggregated
with all other Losses of all Indemnified Persons, exceeds $25,000 (the "Minimum
Aggregate Liability Amount"), at which time Losses may be asserted for any
amounts in excess of the Minimum Aggregate Liability Amount up to the Maximum
Liability Amount (defined below).

               (2) The maximum aggregate liability of the Shareholders for any
Loss shall be limited as follows (the "Maximum Liability Amount"):

               A.  The Maximum Liability Amount for any Loss arising out of or
resulting from a breach, inaccuracy or untruth of a Warranty contained in
Article III or Sections 4.1 and 4.13 shall be $1,500,000; and


                                       27
<PAGE>   29
               B.  The Maximum Liability Amount for any other Loss shall be
limited to $500,000.

               (3) Notwithstanding subsections 6.7(b)(1) and 6.7(b)(2) above,
the Minimum Aggregate Liability Amount and the Maximum Liability Amount shall
not apply to any Loss (A) which results from or arises out of fraud or
intentional misrepresentation or an intentional breach of Warranty on the part
of any Shareholder, (B) claimed with respect to Section 4.6, (C) which results
from or arises out of a breach of Section 6.8 or 6.9, or (D) described in
Section 6.7(a)(vi). For any Loss or Losses not subject to the Minimum Aggregate
Liability Amount or the Maximum Liability Amount, the Indemnified Persons shall
be entitled to indemnification regardless of the amount of the Loss.

               (4) Kevin Davidson shall be responsible for the first $250,000 of
any Loss arising out of Sections 4.13(h) or 4.13(i) hereof. Thereafter, the
Shareholders shall be jointly and severally liable under Section 6.7(a).

               (5) Each Shareholder severally, not jointly, shall indemnify,
reimburse and hold harmless the Indemnified Persons for any Loss as a result of,
or in connection with, any breach of, or noncompliance by, that Shareholder of
the agreements contained in Sections 6.8 or 6.9 hereof.

               (c) Notice of Claim. To seek indemnification hereunder, an
Indemnified Person shall notify each Shareholder of any claim for
indemnification, specifying in reasonable detail the nature of the Loss and the
amount or an estimate of the amount thereof.

               (d) No Prejudice. Nothing herein shall prevent an Indemnified
Person from making a claim for a Loss hereunder notwithstanding its knowledge of
the Loss or possibility of the Loss on or prior to the Closing Date.

               (e) Other Rights. The indemnities granted hereunder are in
addition to and not in substitution for any other right or remedy an Indemnified
Person may now have or may subsequently take or hold, and may be enforced
without first recourse to such other right or remedy and without taking any
steps or proceedings in connection therewith, and notwithstanding any rule of
law or equity or statutory provision to the contrary.


                                       28
<PAGE>   30
               (f) Duty to Mitigate. The Indemnified Persons shall have the duty
to mitigate, to the extent reasonably practicable, any damages for which they
seek indemnification hereunder.

               (g) Setoff. ISC shall satisfy any indemnity right it may have
under Section 6.7(a) first by setoff against any amount payable by ISC to any
Shareholder under the Notes; provided, however, ISC shall have the right to seek
indemnification directly from the Shareholders if the Notes are insufficient to
satisfy ISC's indemnity right because ISC pays the Notes in full before May 30,
2000 or because ISC seeks indemnification for a Loss of the type described in
subsections 6.7(b)(3)(A)-(D) hereof.

         VI.8  Confidentiality.

               (a) Except as provided in the Employment Letter between Francis

three (3) years from the date hereof, and shall hold in trust and confidence all
Trade Secrets (as defined below) for as long as such information remains a trade
secret under applicable law, and shall not make any copies of, distribute or use

the completion of the transactions contemplated under this Agreement. Upon the
first request in writing from ISC, Shareholders shall return to ISC all

                   (1) "Confidential Information" means all information relating

reasonably extend from time to time, any part of or improvements to that
information, and any recommendation, test or report of QS, ISC or any Affiliate

form, translated from the original form, recompiled, made into a compilation,
wholly or partially copied, modified, updated or otherwise altered, or

formula, a pattern, a compilation, a program, a device, a method, a technique, a
drawing, a process, financial data, financial plans, product plans, or a list of
actual or potential customers or suppliers) which (i) derives economic value,

ascertainable by proper means by, other persons who can obtain economic value
from its disclosure or use, and (ii) is the subject of efforts that are
reasonable under the circumstances to maintain its secrecy.

                            STOCK PURCHASE AGREEMENT

                                     BETWEEN

                             OAK INVESTMENT PARTNERS

                                       AND

                         INTELLIGENT SYSTEMS CORPORATION

                                 DATED 3/31/97

<PAGE>   2
                            STOCK PURCHASE AGREEMENT

         This Stock Purchase Agreement (the "Agreement") is made March 31, 1997,
by and among Intelligent Systems Corporation, a Georgia corporation ("Seller"),
on the one hand, and Oak Investment Partners V, Limited Partnership and Oak V
Affiliates Fund, Limited Partnership, both Delaware limited partnerships
("Buyers"), on the other hand. Seller owns shares of common stock, $.01 par
value ("Common Stock"), of PaySys International, Inc., a Florida corporation
("PaySys"). Seller desires to sell a portion of the Common Stock to Buyers, and
Buyers desire to purchase such portion of the Common Stock. Therefore, in
consideration of the mutual covenants and conditions contained herein, the
parties do hereby agree as follows.

1.       Purchase and Sale of Common Stock.

         (a)      Sale and Purchase of Common Stock. Subject to the terms and
conditions set forth in this Agreement, Seller hereby sells to Buyers, and
Buyers hereby purchase from Seller, an aggregate of 50,537 shares of the Common
Stock (the "Shares").

         (b)      Purchase Price. Simultaneously with the execution and delivery
of this Agreement, Buyers shall pay Seller an aggregate of Two Million Dollars
($2,000,000), the purchase price of the Shares (approximately $39.575 per
Share).

         (c)      Delivery of Shares. Simultaneously with the execution and
delivery of this Agreement, Seller shall deliver to Buyers certificates
representing all of the Shares, in such separate denominations as Buyers shall
determine, endorsed in blank for transfer to Buyers or accompanied by a stock
transfer power executed in blank.

2.       Obligation to Transfer Additional Shares.

         (a)      If PaySys is a Public Company in One Year. If by the first
anniversary of this Agreement (the "First Anniversary") the Company has sold
shares of the Common Stock to the public pursuant to a registration statement
effective under the Securities Act of 1933 in a firm commitment underwritten
public offering, and if the Average Fair Market Value per Share on the First
Anniversary (as defined below) is less than $51.45 per Share (the "Target Market
Price"), then within 15 days after the First Anniversary Seller shall transfer
to Buyer" for no further consideration a number of shares of Common Stock (the
"Additional Public Shares") determined by dividing $2,600,000 by the Average
Fair Market Value per Share on the First Anniversary, subtracting 50,537 (the
number of Shares) from that number, and rounding up to the nearest whole number
of shares.

         For purpose of this subsection 2(a), "Average Fair Market Value per
Share on the First Anniversary" shall mean the average for the last 20 trading
days before the First Anniversary (or if such public sale was closed during such
20 trading-day-period, the average for the number of trading days immediately
following such public sale and 
<PAGE>   3
before the First Anniversary) of either (i) or (ii) below, whichever is
applicable:

         (i)      if the Common Stock is traded on a national securities
                  exchange, the closing sales price of a share of Common Stock,
                  regular way, on such exchange on each such trading day; or

         (ii)     if the Common Stock is not traded on any national securities
                  exchange, the average of the closing high bid and low-asked
                  prices of the Common Stock on the over-the-counter market on
                  each such trading day, or in the absence of closing bids on a
                  particular trading day, the closing bids on the next preceding
                  trading day on which there were bids.

Such transfer shall be accomplished by Seller delivering to Buyers certificates
representing the Additional Public Shares in such separate denominations as
Buyers shall determine, endorsed in blank for transfer to Buyers or accompanied
by stock transfer powers executed in blank.

         (b)      If PaySys is a Private Company in One Year. If by the First
Anniversary the Company has not sold shares of the Common Stock to the public
pursuant to a registration statement effective under the Securities Act of 1933
in a firm commitment underwritten public offering, then within 15 days after
the First Anniversary Seller shall transfer to Buyers for no further
consideration an aggregate of 18,377 shares of Common Stock (the "Additional
Private Shares"). Such transfer shall be accomplished by Seller delivering to
Buyers certificates representing the Additional Private Shares in such separate
denominations as Buyers shall determine, endorsed in blank for transfer to
Buyers or accompanied by stock transfer powers executed in blank.

         (c)      Adjustments Under Subsections (a) and (b).

                  (i)      If before the First Anniversary the outstanding
shares of Common Stock are changed into or exchanged for a different number or
kind of shares or other securities of PaySys by reason of a stock split, reverse
stock split, combination, stock dividend, recapitalization or reclassification,
the Target Market Price and the aggregate number and kind of Additional Public
Shares or Additional Private Shares shall be appropriately adjusted.

                  (ii)     For purposes of determining the number of Additional
Private Shares, if before the First Anniversary PaySys shall issue any options
or warrants exercisable for Common Stock or for any securities convertible into
Common Stock (other than any options or warrants already identified on Exhibit A
hereto), or shall issue any securities convertible into Common Stock, and the
aggregate price per share of Common Stock to be paid upon the exercise of such
options or warrants, or upon the conversion of such convertible securities (when
added to the price, if any, paid for such convertible securities and allocable
to the shares of Common Stock issuable upon conversion), is less than 


                                       2
<PAGE>   4
$39.575 per share (adjusted if appropriate in any of the events identified in
subsection (c)(i) above), the number of Additional Private Shares shall be
appropriately adjusted to account for the proportionate potential dilution to
the value of the Shares caused by the issuance of such options, warrants or
convertible securities.

         (d)      Restrictions on Transfer. In connection with the contingent
obligation of Seller to transfer either the Additional Public Shares or the
Additional Private Shares to Buyer, Seller agrees that it shall not sell,
transfer, pledge or otherwise encumber 25,000 shares of Common Stock (the
"Restricted Shares") for 13 months after the date hereof, and that a legend will
be affixed to the certificate(s) representing the Restricted Shares referencing
the restrictions contained in this subsection (d).

         (e)      Registration Rights; Further Assurances. Seller shall use its
best efforts to cause PaySys to grant registration rights to Buyers on the same
terms and conditions as any such rights heretofore or hereafter granted by
PaySys to Seller, and shall use its best efforts to provide that the Shares, any
Additional Public Shares and any Additional Private Shares be freely
transferable by Buyers promptly after the consummation of an initial public
offering by PaySys; provided, however, Seller shall not be required to do
anything under this subsection (e) that would, or reasonably could be expected
to, adversely impact PaySys' ability to raise additional funding in a public
offering or otherwise, or SelIer's ability to participate as a selling
shareholder in any such transaction, or otherwise adversely impact the existing
PaySys shareholders.

3.       Representations and Warranties of Seller. Seller hereby represents and

maintain and perfect the security interest hereunder and to enable Bank to
comply with any federal or state law in order to obtain or perfect Bank's
interest in the Collateral or to obtain proceeds of the Collateral.

   F. NOTICE OF CHANGES. Pledgor shall notify Bank immediately of (i) any
material change in the Collateral (ii) a change in Pledgor's residence or
location, (iii) a change in any matter warranted or represented by Pledgor in
this Agreement, or in any of the loan documents relating to the Obligation or
furnished to Bank pursuant to this Agreement, and (iv) the occurrence of an
Event of Default as defined herein.

   G. POSSESSION OF COLLATERAL. Pledgor shall deliver a copy of this Agreement
(or other notice acceptable to Bank) to any Broker, financial intermediary, or
any other person in possession of any of the Collateral or on whose books the
interest of Pledgor in the Collateral appears, and such delivery shall
constitute notice to such person of Bank's security interest in the Collateral
and shall constitute Pledgor's instruction to such person to note Bank's
security interest on their books and records, or deliver to Bank certificates or
other evidence of the Collateral promptly upon Bank's request. Pledgor shall
deliver all investment securities and other instruments and documents which are
a part of the Collateral and in Pledgor's possession to Bank immediately, or if
hereafter acquired, immediately following acquisition, in a form suitable for
transfer by delivery or accompanied by duly executed instruments of transfer or
assignment in blank with signatures appropriately guaranteed in form and
substance suitable to Bank.

   H. CHANGE OF NAME/STATUS. Pledgor shall not change its name, change its
corporate status, use any trade name or engage in any business not reasonably
related to its business as presently conducted.

   I. POWER OF ATTORNEY. Pledgor appoints Bank and any officer thereof as
Pledgor's attorney-in-fact with full power in Pledgor's name and on Pledgor's
behalf to do every act which Pledgor is obligated to do or may be required to do
hereunder; however, nothing in this paragraph shall be construed to obligate
Bank to take any action hereunder nor shall Bank be liable to Pledgor for
failure to take any action hereunder. This appointment shall be deemed a power
coupled with an interest and shall not be terminable as long as the Obligation
is outstanding and shall not terminate on the disability or incompetence of
Pledgor. Without limiting the generality of the foregoing, Bank shall have the
right and power to receive, indorse and collect all checks and other orders for
the payment of money made payable to Pledgor representing any dividend, interest
payment or other distribution payable in respect of the Collateral or any part
thereof.

   J. OTHER PARTIES AND OTHER COLLATERAL. No renewal or extensions of or any
other indulgence with respect to the Obligation or any part thereof, no
modification of the document(s) evidencing the Obligation, no release of any
security, no release of any person (including any maker, indorser, guarantor or
surety) liable on the Obligation, no delay in enforcement of payment, and no
delay or omission or lack of diligence or care in exercising any right or power
with respect to the Obligation or any security therefor or guaranty thereof or
under this Agreement shall in any manner impair or affect the rights of Bank
under any law, hereunder, or under any other agreement pertaining to the
Collateral Bank need not file suit or assert a claim for personal judgment
against any person for any part of the Obligation or set to realize upon any
other security for the Obligation, before foreclosing or otherwise realizing
upon the Collateral. Pledgor waives any right that can be waived to the benefit
of or to require or control application of any other security or proceeds
thereof, and agrees that Bank shall have no duty or obligation to Pledgor to
apply to the Obligation any such other security or proceeds thereof.

   K. WAIVERS BY PLEDGOR. Pledgor waives notice of the creation, advance,
increase, existence, extension or renewal of, and of any indulgence with respect
to, the Obligation; waives presentment, demand, notice of dishonor, and protest;
waives notice of the amount of the Obligation outstanding at any time, notice of
any change in financial condition of any person liable for the Obligation or any
part thereof, notice of any Event of Default, and all other 


                                       2-
<PAGE>   3
notices respecting the Obligation; and agrees that maturity of the Obligation
and any part thereof may be accelerated, extended or renewed one or more times
by Bank in its discretion, without notice to Pledgor. Pledgor waives any right
to require that any action be brought against any other person or to require
that resort be had to any other security or to any balance of any deposit
account. Pledgor further waives any right of subrogation or to enforce any right
of action against any other Pledgor until the Obligation is paid in full.

   L. WAIVER OF NOTICE FOR IMMEDIATE WRIT OF POSSESSION. Pledgor hereby
acknowledges that the indebtedness arises out of a 'commercial transaction" as
that term is defined in the O.C.G.A. Sec. 44-12-260(1) concerning foreclosure of
mortgages on personally, and agrees that if a default has occurred and is
continuing, Bank shall have the right to an immediate writ of possession without
notice of hearing, and Pledgor hereby knowingly and intelligently waives any and
all rights it may have to any notice and posting of a bond prior to seizure by
Bank, its transferees, assigns or successors in interest of the Collateral or
any portion thereof. The foregoing is intended by Pledgor as a "waiver" as that
term is defined in the O.C.G.A. Sec 44-14-260 (3) relating to foreclosure of
mortgages on personalty.

   M. ADDITIONAL PROVISIONS. If one or more Riders to this Agreement are
executed by Pledgor, the covenants and provisions of each such Rider shall be
incorporated by reference into this Agreement.

      RULE 144 RIDER: The Collateral is comprised in whole or in part of control
and/or restricted securities, which shall be subject to the additional terms and
provisions described on the Rule 144 Rider attached hereto and made a part
hereof for all purposes.

6.   MAINTENANCE OF COLLATERAL.

   A. MAINTENANCE OF COLLATERAL. At all times during the term of the Agreement,
Pledgor agrees to maintain as security for the Obligation Collateral of a type
described on Schedule I with an Adjusted Collateral Value (as determined herein)
in excess of the unpaid principal balance of the Obligation. The Adjusted
Collateral Value shall be determined by multiplying the Collateral Value As
defined in subparagraph B below) by the Margin Call Percentage shown on Schedule
I for the type of Collateral securing the Obligation.

      No advance requested by Pledgor shall be made to Pledgor if the sum of (i)
the outstanding principal balance of the Obligation plus (ii) the amount of the
advance requested, equals or exceeds the sum of the amounts determined by
multiplying the Collateral Value by the Original Advance Percentage for each
type of Collateral securing the Obligation.

   B. VALUE OF COLLATERAL. The "Collateral Value" of Collateral shall be
determined at any given time as follows:

     i. If stock, the Collateral Value shall be determined by multiplying (i)
the per share price of such stock at the most recent close of trading on a
trading exchange for such stock, times (ii) the number of shares of such stock
held by Bank as Collateral. In the event that stock held as Collateral is not
traded on an exchange, the Collateral Value of such stock shall be determined by
obtaining the quoted value of such stock from a reputable brokerage firm
selected by Bank. If no such quote is available, the value will be determined by
Bank in its sole discretion.

     ii. If a mutual fund, the Collateral Value shall be determined by
multiplying (i) the most recent per share asset value of such mutual fund
obtained from the Wall Street Journal, times (ii) the number of shares of such
mutual fund held by Bank as Collateral. In the event that such net asset value
is not available in the Wall Street Journal, the Collateral Value shall be the
value quoted to Bank by a reputable brokerage firm selected by Bank.

     iii. If corporate bonds, the Collateral Value shall be determined from the
most recent closing price for such bonds obtained from the Wall Street Journal.
If such closing price is not available in the Wall Street Journal, the
Collateral Value shall be the value quoted to Bank by a reputable brokerage firm
selected by Bank.

     iv. If government or agency obligations or bonds, the Collateral Value
shall be determined from the most recent closing bid price for such bonds
obtained from the Wall Street Journal. If such closing bid price is not
available in the Wall Street Journal, the Collateral Value shall be the value
quoted to Bank by a reputable brokerage firm selected by Bank.

     v. If other than stock, mutual funds, corporate bonds, or government or
agency obligations or bonds, the Collateral Value shall be determined by the
Bank in its sole discretion.

   C. BREACH OF COLLATERAL MAINTENANCE. Pledgor agrees that the failure to
maintain Collateral with an Adjusted Collateral Value as set forth above shall
constitute an Event of Default under this Agreement. In such event, the Pledgor
shall have two business days from the date Pledgor is notified by Bank (in
writing or orally) of such noncompliance, or such notice is otherwise delivered
to Pledgor, to either pledge additional Collateral satisfactory to Bank, in its
sole discretion, or reduce the unpaid principal balance of the Obligations such
that, in either case, the unpaid principal balance of the Obligation is less
than the sum of the amounts determined by multiplying the Collateral Value by
the Original Advance Percentage shown on Schedule I for each type of Collateral
securing the Obligation. Any reduction in unpaid principal of the Obligation
shall not affect or reduce any future principal payments due except to the
extent such reductions are applied in accordance with the documents evidencing
or securing the Obligation In the event Pledgor fails to comply with the terms
hereof, Bank may, without any further notice of any kind, exercise any of the
following rights and remedies, at Bank's option:

   i.  The rights and remedies set out in Section 8.B. of this Agreement,
including without limitation the right to accelerate the Obligation and
liquidate the Collateral.

   ii. Sell all or any part of the Collateral and apply the proceeds of such
sale to the Obligation to bring the Obligation back into compliance ( that is,
to reduce the unpaid principal of the Obligation such that the unpaid principal
of the Obligation is less than the sum of the amounts determined by multiplying
the Collateral Value by the Original Advance Percentage shown on Schedule I for
each type of Collateral securing the Obligation).

If an Event of Default exists hereunder and the Collateral is declining in value
or threatens to decline speedily in value, Bank shall have no obligation to
notify Pledgor of the failure to maintain Collateral with an Adjusted Collateral
Value as set forth in subparagraph A above or to provide Pledgor with an
opportunity to cure such noncompliance, and in such case Pledgor agrees that
Bank may immediately at Bank's sole option (i) declare amounts due under the
Obligation to be immediately due and payable, and/or (ii) sell all or any part
of the Collateral and apply the proceeds of such Collateral to the Obligation.

   D. SALE OR SUBSTITUTION OF COLLATERAL. If no Event of Default has occurred
under this Agreement or would result from such action, Pledgor may (i) sell,
trade, or withdraw any part of the Collateral; or (ii) substitute new Collateral
for existing Collateral, provided that, in either event, the new Collateral
shall be acceptable to Bank in its sole discretion and the unpaid principal
balance of the Obligation shall be less than the sum of the amounts determined
by multiplying the Collateral Value by the Original Advance Percentage for each
type of Collateral securing the Obligation.

7. RIGHTS AND POWERS OF BANK.

   A. GENERAL. Bank, before or after default, without liability to Pledgor may:
take control of proceeds, including stock received as dividends or by reason of
stock splits; release the Collateral in its possession to any Pledgor,
temporarily or otherwise; require additional Collateral; reject as
unsatisfactory any property hereafter offered by Pledgor as Collateral; take
control of funds generated by the Collateral, such as cash dividends, interest
and proceeds, and use same to reduce any part of the Obligation and exercise all
other rights which an owner of such Collateral may exercise, except the right to
vote or dispose of the Collateral before an Event of Default; and at any time
transfer any of the Collateral or evidence thereof into its own name or that of
its nominee. Bank shall not be liable for failure to collect any account or
instruments, or for any act or omission on the part of Bank, its officers,
agents or employees, except for its or their own willful misconduct or gross
negligence. The foregoing rights and powers of Bank will be in addition to, and
not a limitation upon, any rights and powers of Bank given by law, elsewhere in
this Agreement, or otherwise.

   B. CONVERTIBLE COLLATERAL. Bank may present for conversion any Collateral
which is convertible into any other instrument or investment security or a
combination thereof with cash, but Bank shall not have any duty to present for
conversion any Collateral unless it shall have received from Pledgor detailed
written instructions to that effect at a time reasonably far in advance of the
final conversion date to make such conversion possible.

8. DEFAULT.

   A. EVENT OF DEFAULT. An event of default ("Event of Defaults") shall occur
(a) if Pledgor or any other obligor on all or part of the Obligation shall fail
to timely and properly pay or observe, keep or perform any term, covenant,
agreement or condition in this Agreement or in any other agreement between
Pledgor and Bank of between Bank and any other obliger on the Obligation,
including but not limited to any other note or instrument, loan agreement,
security agreement, deed of trust, mortgage, promissory note, assignment or
other agreement or instrument concerning the Obligation; or (b) if Pledgor or
such other obliger shall fail to timely and properly pay or observe, keep or
perform any term, covenant, agreement or condition in any agreement between such
party and any affiliate or subsidiary of NationsBank Corporation.

   B. RIGHTS AND REMEDIES. If any Event of Default shall occur, then, in each
and every such case, Bank may without (a) presentment, demand, or protest, (b)
notice of default, dishonor, demand, non-payment, or protest, (c) notice of
intent to accelerate all or any part of the Obligation, (d) notice of
acceleration of all or any part of the Obligation, or (e) notice of any other
kind, all of which Pledgor hereby expressly waives (except for any notice
required under this Agreement, any other loan document or which may not be
waived under applicable law), at any time thereafter exercise and/or enforce any
of the following rights and remedies, at Bank's option:

      i. ACCELERATION. The Obligation shall, at Bank's option, become
immediately due and payable, and the obligation, if any, of Bank to permit
further borrowings under the Obligation shall at Bank's option immediately cease
and terminate.

      ii. LIQUIDATION OF COLLATERAL. Sell, or instruct any Agent or Broker to
sell, all or any part of the Collateral in a public or private sale, direct any
Agent or Broker to liquidate all or any part of any Account and deliver all
proceeds thereof to Bank, and apply all proceeds to the payment of any or all of
the Obligation in such order and manner as Bank shall, in its discretion,
choose.

      iii. UNIFORM COMMERCIAL CODE. All of the rights, powers and remedies of a
secured creditor under the Uniform Commercial Code ("UCC") as adopted in the
jurisdiction to which Bank is subject under this Agreement.

      iv. RIGHT OF SET OFF. Without notice or demand to Pledgor, set off and
apply against any and all of the Obligation any and all deposits (general or
special, time or demand, provisional or final) and any other indebtedness at any
time held or owing by Bank or by any of Bank's affiliates or correspondents to
or for the credit of the account of Pledgor or any guarantor or indorser of
Pledgor's Obligation.

Pledgor specifically understands and agrees that any sale by Bank of all or part
of the Collateral pursuant to the terms of this Agreement may be effected by
Bank at times and in manners which could result in the proceeds of such sale as
being significantly and materially less than might have been received if such
sale had occurred at different times or in different manners, and Pledgor hereby
releases Bank and its officers and representatives from and against any and all
obligations and liabilities arising out of or related to the timing or manner of
any such sale.

If, in the opinion of Bank, there is any question that a public sale or
distribution of any Collateral will violate any state or federal securities law,
Bank may offer and sell such Collateral in a transaction exempt from
registration under federal securities law, and any such sale made in good faith
by Bank shall be deemed "commercially reasonable."

9. GENERAL.

   A. PARTIES BOUND. Bank's rights hereunder shall inure to the benefit of its
successors and assigns, and in the event of any assignment or transfer of any of
the Obligation or the Collateral, Bank thereafter shall be fully discharged from
any responsibility with respect to the Collateral so assigned or transferred,
but Bank shall retain all rights and powers hereby given with respect to any of
the Obligation or the Collateral not so assigned or transferred. All
representation warranties and agreements of Pledgor if more than one are joint
and several and all shall be binding upon the person representatives, heirs,
successors and assigns of Pledgor.

   B. WAIVER. No delay of Bank in exercising any power or right shall operate as
a waiver thereof; nor shall any single or partial exercise of any power or right
preclude other or further exercise thereof or the exercise of any other power or
right. No waiver by Bank of any right hereunder or of any default by Pledgor
shall be binding upon Bank unless in writing, and no failure by Bank to exercise
any power or right hereunder or waiver of any default by Pledgor shall operate
as a waiver of any other or further exercise of such right or power or of any
further default. Each right power and remedy of Bank as provided for herein or
in any of the loan documents related to the Obligation, or which shall now or
hereafter exist at law or in equity or by statute or otherwise, shall be
cumulative and concurrent and shall be in addition to every other such right,
power or remedy. The exercise or beginning of the exercise by Bank of any one or
more of such rights, powers or remedies shall not preclude the simultaneous or
later exercise by Bank of any or all other such rights, powers or remedies.

agreement. If the Obligation consists of All Debt, this Agreement shall apply to
