  The following summary is qualified in its entirety by the more detailed
information, including information set forth in "Risk Factors" and the
Consolidated Financial Statements and Notes thereto, appearing elsewhere in
this Prospectus. This Prospectus contains forward-looking statements which
involve risks and uncertainties. The Company's actual results may differ
materially from those results discussed in these forward-looking statements and
from the results historically experienced. Factors that might cause such a
difference include, but are not limited to, those discussed in "Risk Factors."
    
                                  THE COMPANY
   
  Software AG Systems, Inc. is an enterprise solutions company that provides
robust software products and related professional services to large
organizations with complex computing requirements. The Company's products are
used to build and enhance mission-critical applications that require
reliability, scaleability and security, such as customer billing systems,
financial accounting systems and inventory management systems. To complement
its products, the Company has a comprehensive professional services offering,
including consulting, software integration, systems implementation and large
project management services. The Company has over 24 years of experience in
addressing the needs of organizations with complex enterprise level computing
environments.     
   
  The Company provides enterprise development software products and related
professional services used by organizations to develop new mission-critical
applications and enterprise enablement software products and related
professional services used to extend existing applications to new technologies.
The Company's enterprise development products include ADABAS, a high-
performance database management system designed to operate with a variety of
data types and computer platforms, and NATURAL, a 4GL programming language that
enables the development of applications that are portable, scaleable and
interoperable across multiple computing platforms. The Company also provides
software products and professional services that enable organizations to extend
existing mission-critical applications to the Internet and intranets and to
create new applications. Products in this area include ENTIRE, a family of
middleware products that facilitates the communication between application
components across heterogeneous computing environments; SourcePoint, an
automated data warehouse management product; iXpress, a Web application
assembly and deployment platform; and EntireX DCOM, a product that uses
Microsoft's ActiveX technology to bridge applications written in a variety of
programming languages. The Company's professional services that complement its
products include application development and enhancement, application
reengineering, application porting and rightsizing, Web integration and data
warehouse design and implementation.     
   
  The Company has a rapidly growing Year 2000 Program which offers a new,
internally developed software product, INSIGHT 2000 Tool Kit, as well as
project management and consulting services to assist customers in the
resolution of their year 2000 problem. The Company believes that there are over
one billion lines of NATURAL code in the United States alone, most of which are
candidates for year 2000 analysis, remediation and testing. To address this
opportunity, the Company has hired 78 new consultants in the first nine months
of 1997 and has opened three Millenium Centers for code analysis, remediation
and testing.     
   
  The Company's strategy is to further leverage its current leadership position
in building enterprise applications and data access solutions for large
organizations by extending its product and professional service offerings into
the Web integration, data warehouse, middleware and year 2000 markets. Key
elements of this strategy include enhancing and extending product offerings
through acquisitions of complementary products or technologies; internal
product development and licensing additional products; leveraging the Company's
current base of over 1,500 customers; expanding the Company's professional
service offerings; and selling additional products and professional services
through the Company's distribution channels.     
 
  On March 31, 1997, the senior management of the Company and Thayer Equity
Investors III, L.P. ("Thayer") acquired approximately 89% of the outstanding
Common Stock of the Company (the
 
                                       4
<PAGE>
 
"Recapitalization"). Prior to the Recapitalization, the Company was a wholly
owned subsidiary of Software AG, a large German software company ("SAG"), and
the Company's management was constrained in its ability to develop new
products, license third-party software, retain capital for expansion and make
acquisitions of companies, products or technologies. Management has undertaken
several strategic initiatives since the Recapitalization to increase revenue
growth and profitability including building a product development organization,
developing a product and professional services offering that addresses the year
2000 problem and acquiring R. D. Nickel and Associates Incorporated ("R.D.
Nickel"), a software company with a family of application development products.
The Company believes that, as an independent entity, it will continue to have
significant opportunities to enhance growth.
   
  Immediately prior to the Recapitalization, the Company renegotiated its
licensing agreement with SAG (as renegotiated, the "Cooperation Agreement") to
provide the Company the exclusive and perpetual right to license and service in
North America, South America, Japan and Israel (collectively, the "Territory")
both existing and future products developed or acquired by SAG.     
   
  The Company sells and markets its software products and professional services
through direct and indirect channels. In North America, the Company sells and
markets its products through a direct channel that includes over 120 people in
19 offices. The Company sells its products in over 20 additional countries
through six exclusive distributorships in South America, Japan and Israel. In
addition, the Company has access to the distribution channels of SAG in over 50
countries outside the Territory for the Company's products (other than those
licensed from SAG). The Company recently implemented a reorganization of its
sales force into three groups that focus separately on selling Enterprise
License Agreements ("ELAs"), professional services and the Year 2000 Program.
The Company believes that this reorganization and the resulting productivity
improvements in its sales force have contributed to its revenue growth since
the Recapitalization.     
   
  The Company has over 1,500 customers, consisting primarily of major
corporations, government agencies and educational institutions. The Company's
customers include Morgan Stanley, Dean Witter, Discover & Co., Delta Air Lines,
Inc., Sprint Corporation, Federal Express Corp., Nissan Motor Co., LTD., Cable
and Wireless, PLC, Banorte Bank (Mexico), State of California, State of New
Jersey, Federal Bureau of Investigation, Brown University and the University of
Texas. Most of the Company's customers have been long term users of its
products and services. For the twelve months ended September 30, 1997,
approximately 96% of the Company's customers who were eligible renewed at least
one of their maintenance agreements.

                                 RISK FACTORS
 
  This Prospectus contains forward-looking statements which involve risks and
uncertainties. The Company's actual results could differ materially from those
anticipated in these forward-looking statements and from the results
historically experienced as a result of certain factors, including those in
the following risk factors and elsewhere in this Prospectus. In addition to
the other information contained in this Prospectus, the following risk factors
should be considered carefully in evaluating the Company and its business
before purchasing shares of the Common Stock offered hereby.
 
POTENTIAL FLUCTUATIONS IN QUARTERLY PERFORMANCE
   
  The Company has experienced significant quarterly and other fluctuations in
revenues and results of operations and expects these fluctuations to continue
in the future. The Company believes that these fluctuations have been
primarily attributable to the budgeting and purchasing practices of its
customers, and, to a lesser extent, the Company's sales commission practices,
which are based partly on annual quotas, and other factors. The Company's
revenues and results of operations may also be affected by seasonal trends
which have resulted in higher revenues in the Company's third and fourth
quarters and lower revenues in its first and second quarters. The Company's
professional services fees tend to fluctuate due to the completion or
commencement of significant projects, the number of working days in a quarter
and the Company's ability to attract, retain and efficiently utilize
professional services personnel. The Company's future revenues and operating
results may fluctuate as a result of these and other factors, including the
demand for the Company's products and services, the timing and cost of new
product and service introductions and product enhancements by the Company or
its competitors, changes in the mix of products and services sold by the
Company and in the mix of sales by distribution channels, commencement or
conclusion of significant service contracts, timing of any acquisitions and
associated costs, the size, timing and terms of customer orders, including
delays in significant orders, changes in pricing policies by the Company or
its competitors, the timing of collection of accounts receivable, changes in
foreign currency exchange rates, competitive conditions in the industry and
general economic conditions.     
   
  The Company's expense levels are based, in part, on its expectation of
future revenues, and expense levels are, to a large extent, fixed in the short
term. The Company may be unable to adjust spending in a timely manner to
compensate for any unexpected revenue shortfall. If revenue levels are below
expectations for any reason, the Company's results of operations are likely to
be materially and adversely affected. The Company's net income may be
disproportionately affected by a reduction in revenue because a large portion
of the Company's expenses cannot be easily reduced. In addition, the Company
intends to increase its operating expenses by expanding its software product
development staff, increasing its professional services and sales and
marketing operations, expanding its distribution channels and hiring personnel
in other operating areas. The Company expects to experience a significant time
lag between the date professional services, sales and technical personnel are
hired and the date such personnel become fully productive. The timing of such
expansion and the rate at which new technical, professional services and sales
personnel become productive as well as the timing of the introduction and the
productivity of new distribution channels could cause material fluctuations in
quarterly results of operations. Furthermore, to the extent such increased
operating expenses precede or are not subsequently followed by increased
revenues, the Company's business, financial condition and results of
operations could be materially and adversely affected.     
   
  Due to all of the foregoing factors, it is likely that in some future
periods the Company's revenues or results of operations will be below the
expectations of securities analysts or investors, in which case the market
price of the Common Stock would likely be materially and adversely affected.
See "Management's Discussion and Analysis of Financial Conditions and Results
of Operations--Quarterly Results of Operations."     
 
RELATIONSHIP WITH SAG
   
  The Company has the exclusive and perpetual right to license and service in
North America, South America, Japan and Israel both existing and future
products developed or acquired by SAG and, historically,     
 
                                       7
<PAGE>
 
   
substantially all of the Company's revenues have been derived from the
licensing and servicing of products developed or acquired by SAG. As a result,
a materially adverse change in the financial condition, or a change in
control, of SAG could have a material adverse effect on the business,
financial condition and results of operations of the Company. In the past, SAG
has reported operating losses. In addition, the failure of SAG to develop new
products or enhancements to existing products in a timely manner, to provide
ongoing technical support for its products or to adequately protect its
proprietary rights could have a material adverse effect on the business,
financial condition and results of operations of the Company. In the past, the
Company has experienced delays in receiving products from SAG in a timely
manner. The Cooperation Agreement requires SAG to ensure that its products are
year 2000 compliant in accordance with a specific timetable and any failure by
SAG to adhere to that timetable also could have a material adverse effect on
the Company's business, financial condition and results of operations. In 1995
and 1996, the Company's aggregate royalty payments to SAG were $23.9 million
and $26.1 million, respectively. To the extent that the Company's aggregate
royalty payments to SAG fall below $21.0 million in any calendar year through
the year 2000, the Company generally is required to pay the differential to
SAG, and any such payment could have a material adverse effect on the
Company's business, financial condition and results of operations.     
   
  SAG has the exclusive and perpetual right to license and service in all
territories other than North America, South America, Japan and Israel both
existing and future products developed or acquired by the Company. As a
result, the Company is dependent on SAG for the distribution of these products
outside of North America, South America, Japan and Israel. Any failure by SAG
to distribute such products in a timely and effective manner could have a
material adverse effect on the Company's business, financial condition and
results of operations. See "Company Background."     
 
TECHNOLOGICAL CHANGE; DEPENDENCE ON NEW PRODUCTS AND PRODUCT ENHANCEMENTS
   
  The Company operates in a rapidly changing technological environment in
which it must keep pace with new technologies and competitive forces in order
to be successful. The Company's success will depend in part on its ability to
acquire and/or develop product enhancements and new products that keep pace
with continuing changes in technology and evolving customer preferences. There
can be no assurance that the Company will be successful in acquiring and/or
developing product enhancements or new products to adequately address changing
technologies, that it can introduce such products or enhancements on a timely
basis or that any such products or enhancements will be successful in the
marketplace. The Company's failure to acquire and/or develop technological
improvements or to adapt its products to technological change may have a
material adverse effect on the Company's business, financial condition and
results of operations.     
 
DEPENDENCE ON THE YEAR 2000 MARKET
   
  The Company believes that its future growth depends, in part, on increased
demand for the Company's products and professional services relating to the
resolution of the year 2000 problem. The Company had no revenues from its Year
2000 Program in 1996. For the nine months ended September 30, 1997, the
Company had revenues of $3.7 million from its Year 2000 Program. Although the
Company believes that the market for products and professional services
relating to the year 2000 problem will grow as the year 2000 approaches, there
can be no assurance that this market will develop to the extent anticipated by
the Company. Significant expenses for sales and marketing may be required to
educate potential clients of the year 2000 problem and the need for products
and professional services addressing the problem. There can be no assurance
that potential clients will understand or acknowledge the problem. In
addition, affected organizations may not be willing or able to allocate the
resources, financial or otherwise, to address the problem in a timely manner.
Many organizations may attempt to resolve the problem internally rather than
by contracting with outside firms such as the Company and value added
integrators to which the Company may license its software products. Due to
these and other factors, development of the market for the Company's year 2000
products and professional services is uncertain and unpredictable. In
addition, the Company anticipates that demand for products and professional
services that address the year 2000 problem will decline, perhaps rapidly,
following the year 2000.     
 
                                       8
<PAGE>
 
If the market for year 2000 products and professional services fails to grow,
or grows more slowly than anticipated, the Company's business, financial
condition and results of operations could be materially adversely affected. In
addition, competition for personnel qualified to perform professional services
relating to the year 2000 problem is intense, and there can be no assurance
that the Company will be able to retain its employees who provide such
professional services or be able to attract and retain such personnel in the
future.
 
RELIANCE ON ACQUISITIONS
   
  The Company believes that its future growth will depend, in part, on its
ability to successfully identify, acquire and then develop promising
technologies and products. In addition, the Company intends to build its
product development staff in part through acquisitions. On September 30, 1997,
the Company acquired R.D. Nickel. The integration of R.D. Nickel or any other
future acquisitions into the Company's existing business could result in
certain unanticipated difficulties that could require a disproportionate
amount of management's attention and the Company's resources. Furthermore,
there can be no assurance that the anticipated benefits of acquiring R.D.
Nickel or any other future acquisition will be realized. The Company has
limited experience in completing acquisitions and integrating acquired
technologies or products into its operations. The Company may compete for
future acquisition opportunities with other companies that have significantly
greater financial and management resources. While the Company is continually
searching for acquisition opportunities, the Company is not currently a party
to any agreements, understandings or negotiations with respect to any material
acquisition, and there can be no assurance that the Company will be successful
in identifying, acquiring and developing products and technology. Acquisitions
could also have adverse short-term effects on the Company's operating results,
and could result in dilutive issuances of equity securities and the incurrence
of debt and contingent liabilities. In addition, many business acquisitions
must be accounted for as purchases and, because most software-related
acquisitions involve the purchase of significant intangible assets, these
acquisitions typically result in substantial amortization charges and may also
involve charges for acquired research and development projects, which could
have a material adverse effect on the Company's operating results. The Company
has incurred significant charges of this nature in connection with its
acquisition of R.D. Nickel. See "Company Background."     
 
MANAGEMENT OF PROFESSIONAL SERVICES GROWTH
   
  The Company recently has experienced a period of growth in its professional
services business, with revenues from such business increasing from $27.0
million for the nine months ended September 30, 1996 to $31.0 million for the
nine months ended September 30, 1997. The Company's ability to staff and
effectively manage any future growth in this business will require it to
continue to improve its operational, financial and management controls and
reporting systems and procedures, and to hire, train, motivate and manage its
professional services employees. There can be no assurance that the Company
will be able to manage these challenges in an efficient or timely manner. If
management of the Company is unable to manage growth effectively, the
Company's business, financial condition and results of operations could be
materially adversely affected.     
 
DEPENDENCE ON CUSTOMER BASE
   
  Most of the Company's sales are made to its existing customers. Customers
typically pay a one-time licensing fee for use of the Company's products and
generally pay an annual charge for maintenance services which include software
updates and technical support. There can be no assurance that customers will
continue to purchase the Company's products and services, that the Company's
historic maintenance renewal rates will continue, or that the Company will be
able to maintain its current pricing levels for products and maintenance
services. Customers' decisions not to renew their maintenance agreements or to
renew them on different terms could have a material adverse effect on the
Company's business, financial condition and results of operations.     
 
RELIANCE ON MAINFRAME COMPUTING ENVIRONMENT
 
  The majority of the Company's products are purchased by customers using IBM
and IBM-compatible mainframe computing platforms. Worldwide, an increasing
proportion of computing functions are being
 
                                       9
<PAGE>
 
performed on alternative computing platforms, including mid-range computers
and client/server networks. A significant shift in the way the Company's
customers use computing platforms may have a material adverse effect on the
Company's business, financial condition and results of operations. In
addition, although the Company believes that any migration away from mainframe
computing platforms is subsiding as a result of more cost effective mainframe
technology and other factors, any further significant reduction in the role of
mainframe or other legacy systems could have a material adverse effect on the
Company's business, financial condition and results of operations.
 
PROPRIETARY TECHNOLOGY
   
  The Company's success is dependent to a significant extent on its ability to
protect its proprietary rights. The Company has no patents and depends upon a
combination of trade secret, copyright and trademark laws, license agreements,
nondisclosure, assignment of invention and other contractual provisions, and
various security measures to protect its proprietary rights. The Company is
also dependent on SAG and other third parties that license products to the
Company to protect their respective proprietary rights in such products. There
can be no assurance that the legal protections afforded to, or the precautions
taken by, the Company or its third-party licensors will be adequate to prevent
misappropriation of their respective proprietary rights. In addition, these
protections do not prevent independent third-party development of functionally
equivalent or superior technologies, products or professional services. Any
infringement or misappropriation of the Company's proprietary rights, or those
of its third-party licensors, could have a material adverse effect on the
Company's business, financial condition and results of operations.     
   
  In the future, litigation may be necessary to enforce and protect the
Company's trade secrets, copyrights and other intellectual property or
proprietary rights. The Company may also be subject to litigation to defend
against claimed infringement of, or to determine the scope and validity of,
the intellectual property or proprietary rights of others. In the event of
litigation involving the use of technology by the Company, the Company could
be required to expend significant resources to develop non-infringing
technology or to obtain licenses to technology involved in litigation. There
can be no assurance that the Company would be successful in such development
or that any such licenses would be available on commercially reasonable terms,
if at all. Although the Company is not aware that its products, trademarks or
other proprietary rights infringe upon the proprietary rights of third
parties, there can be no assurance that third parties will not assert
infringement claims against the Company and that such claims will not have a
material adverse effect on the Company's business, financial condition and
results of operations. Any litigation involving the use of technology by the
Company could result in substantial cost to the Company and divert
management's attention from the Company's operations, either of which could
have a material adverse effect on the Company's business, financial condition
and results of operations. Adverse determinations in such litigation could
result in the loss of the Company's proprietary rights, subject the Company to
significant liabilities, require the Company to seek licenses from third
parties or prevent the Company from selling its products, any one of which
could have a material adverse effect on the Company's business, financial
condition and results of operations. See "Business--Proprietary Rights."     
 
DEPENDENCE ON THIRD-PARTY TECHNOLOGY
   
  The Company's products are currently designed, and may in the future be
designed, to work on or in conjunction with certain third-party hardware
and/or software products. If any of these current or future third- party
vendors were to discontinue making their products available to the Company or
to licensees of the Company's products or to increase materially the cost to
the Company or its licensees to acquire, license or purchase such third-party
vendor's products, or if a material problem were to arise in connection with
the ability of the Company's products to properly use or operate with third-
party hardware and/or software products, the Company's products would have to
be redesigned by the Company, or the licensor of the product to the Company,
to function with or on alternative third-party products. There can be no
assurance that an alternative source of suitable technology would be available
or that the Company, or the licensor of the product to the Company, would be
able to develop an alternative product on a timely basis or at a reasonable
cost. The failure of the Company to license, acquire or develop alternative
technologies or products     
 
                                      10
<PAGE>
 
on a timely basis and at a reasonable cost could have a material adverse
effect on the Company's business, financial condition and results of
operations.
 
COMPETITION
   
  The markets for the Company's software products and professional services
are highly competitive and characterized by continual change and improvement
in technology. The Company provides products and professional services to
several markets within the computer industry and encounters competitors within
each such market. Many of the Company's competitors have significantly greater
financial, marketing and other competitive resources than the Company. The
Company's principal competitors currently include IBM Corporation ("IBM"),
Oracle Corporation ("Oracle"), Microsoft Corporation ("Microsoft"), Informix
Corporation ("Informix"), PLATINUM Technology, Inc. ("PLATINUM"), Sybase, Inc.
("Sybase"), VIASOFT, Inc. ("Viasoft"), Sterling Software, Inc. ("Sterling
Software"), Visigenic Software, Inc. ("Visigenic"), SAS Institute, Inc.
("SAS"), Formal Systems, Inc. ("Formal Systems"), BDM International, Inc.
("BDM") and Electronic Data Systems Corporation ("EDS"). Few of the Company's
competitors compete in all of the same markets as the Company. In certain
markets in which the Company competes, such as the year 2000 market, there are
no significant barriers to entry. Current and potential competitors may
introduce new and better products, make strategic acquisitions, or establish
cooperative relationships among themselves or with third parties, thereby
increasing the ability of their products to address the needs of the Company's
current and prospective customers. There can be no assurance that the Company
will be able to compete successfully against current and future competitors,
and its failure to do so would have a material adverse effect upon the
Company's business, financial condition and results of operations. In
addition, no assurance can be given that the Company will not be required to
make substantial additional investments in connection with its research,
development, marketing, sales and customer service efforts in order to meet
any competitive threat, or that such required investments will not have a
material adverse effect on operating margins. Increased competition could
result in reduction in market share, pressure for price reductions and related
reductions in gross margins, any of which could materially adversely affect
the Company's business, financial condition and results of operations. See
"Business--Competition."     
 
RISK ASSOCIATED WITH INTERNATIONAL SALES AND OPERATIONS
   
  The Company holds the exclusive and perpetual right to license SAG products
in North America, South America, Japan and Israel. In South America, Japan and
Israel, the Company has entered into exclusive distributorship arrangements
with local firms. The Company's distributorships in South America, Japan and
Israel have been in place for 25, 21 and 19 years, respectively, and
collectively accounted for 11.3% and 11.2% of the Company's total revenues in
1996 and the first nine months of 1997, respectively. There can be no
assurance that such distributors will continue to perform as they have
historically and that they will not offer products that compete with the
Company's products. Additionally, the distributorships generally may be
terminated by either party at any time upon compliance with applicable notice
provisions. In the event that any of the distributorships were terminated or
expired, there can be no assurance that the Company could find an adequate
replacement, and such a termination or expiration could have a material
adverse effect on the Company's business, financial condition and results of
operations. The Company is currently renegotiating its distributorship
arrangements in Japan and South America.     
   
  Sales of products and the provision of services to customers outside the
United States accounted for 15.2% and 17.8% of the Company's total revenues in
1996 and the first nine months of 1997, respectively. The Company anticipates
that revenues from international sales and services will continue to account
for a material portion of its total revenues in the foreseeable future. As a
result, the Company may be subject to certain risks associated with
international operations, including risks associated with foreign currency
exchange rate fluctuations and risks associated with the application and
imposition of protective legislation and regulations relating to import or
export (including export of high technology products) or otherwise resulting
from foreign policy or the variability of foreign economic conditions. To
date, the Company has not engaged in any hedging transactions to mitigate its
risks relating to exchange rate fluctuations. Additional risks associated with
international operations include costs of localizing products for foreign
countries, lack of acceptance of localized products in foreign countries,
difficulties in enforcing intellectual property, proprietary     
 
                                      11
<PAGE>
 
and contract rights, the burdens of complying with a wide variety of foreign
laws, potentially adverse tax consequences, tariffs, quotas and other
barriers, and potential difficulties in collecting accounts receivable. There
can be no assurance that these and other factors will not have a material
adverse effect on the Company's business, financial condition and results of
operations.
 
RISK OF SOFTWARE DEFECTS
 
  Software products as complex as those offered by the Company frequently
contain errors or defects, especially when first introduced or when new
versions or enhancements are released. Despite product testing, new products
may contain defects or software errors and, as a result, the Company may
experience delayed or lost revenues during the period required to correct any
defects or errors. Any such defects or errors could result in adverse customer
reactions, negative publicity regarding the Company and its products, harm to
the Company's reputation, or loss of or delay in market acceptance, or could
require expensive product changes, any of which could have a material adverse
effect upon the Company's business, financial condition and results of
operations. The Company's Cooperation Agreement with SAG provides for only
limited warranties by SAG with respect to the software products licensed by it
to the Company and, therefore, the Company may be primarily liable to its
customers for defects in SAG-supplied software.
 
POTENTIAL FOR CONTRACT LIABILITY
   
  The Company markets its products and professional services to customers for
developing, building, deploying, maintaining and managing mission-critical
computer software applications and for addressing the year 2000 problem. The
Company's license and other agreements with its customers typically contain
provisions designed to limit the Company's exposure to potential liability
claims relating to the Company's products or professional services. Despite
this precaution, there can be no assurance that the limitations of liability
set forth in the Company's agreements would be enforceable or would otherwise
protect the Company from liability for damages. Although the Company has not
experienced any material liability claims to date, the sale and support of the
Company's products and professional services may entail the risk of such
claims, which could be substantial in light of the use of such products in
mission-critical applications. A material liability claim against the Company,
regardless of its outcome, could result in substantial cost to the Company and
divert management's attention from the Company's operations. Therefore, any
material liability claim could have a material adverse effect on the Company's
business, financial condition and results of operations.     
 
DEPENDENCE ON STATE, LOCAL AND OTHER GOVERNMENT CONTRACTS
   
  The Company derived 23.5% of its total revenues in 1996 and 27.6% of its
total revenues for the first nine months of 1997 from selling its products and
professional services directly or indirectly to state and local government
agencies. In addition, the Company derived 8.9% of its total revenues in 1996
and 9.7% of its total revenues for the first nine months of 1997 from selling
its products and professional services directly or indirectly to federal
government agencies. Any failure to obtain a contract award, or a delay on the
part of a government agency in making the award or in ordering products and
professional services under an awarded contract, could have a material adverse
effect on the Company's business, financial condition and results of
operations. Other risks generally involved in government sales include the
larger discounts (and thus lower margins) typically involved in government
sales, the dependence of the Company on the ability of a prime contractor, if
any, to obtain the award and perform the contract, the unpredictability of
funding for various government programs, the ability of the government agency
to unilaterally terminate the contract, and the dependence on the
creditworthiness of any prime contractor (some of which are relatively small
organizations without substantial funds). The Company anticipates that state,
local and other government sales will continue to represent a significant but
fluctuating portion of its revenues in the future.     
 
FIXED PRICE CONTRACTS
   
  Revenues from fixed price contracts represented approximately 8.0% and 10.3%
of the Company's total revenues for 1996 and the first nine months of 1997,
respectively. In making proposals for fixed price contracts, the Company
relies on its estimated costs for completing the project. These estimates
reflect, among     
 
                                      12
<PAGE>
 
other factors, judgments as to the efficiencies of the Company's technology
and services as applied to the project. Any increased or unexpected costs or
unanticipated delays in connection with the performance of fixed price
contracts could have a material adverse effect on the Company's business,
financial condition and results of operations. In the past, the Company has
suffered material losses on fixed price contracts.
 
DEPENDENCE ON KEY PERSONNEL; NEED TO HIRE ADDITIONAL PERSONNEL
 
  The Company's future performance depends to a significant degree upon the
continued service of the key members of its management, as well as marketing,
sales, consulting and product development personnel, and its ability to
attract and retain new management and other personnel. The loss of any one or
more of the Company's key personnel could have a material adverse effect on
the Company's business, financial condition and results of operations. Company
employees are employed at-will and the Company has no fixed-term employment
agreements with any of its employees.
   
  While historically the Company primarily has relied on SAG for product
development, the Company believes its future success will also depend in part
upon its ability to develop its own technologies and products and,
consequently, upon its ability to attract and retain highly skilled technical
and product development personnel. Competition for such personnel is intense,
and there can be no assurance that the Company will be able to retain its key
employees or that it will be successful in attracting, integrating and
retaining new personnel in the future. Failure to attract, integrate and
retain such personnel could have a material adverse effect on the Company's
business, financial condition and results of operations. In addition, at
September 30, 1997, the Company had 106 independent contractors working as
technical consultants primarily in connection with the Company's professional
service offerings. Competition for such contractors is intense and the failure
to continue to attract and hire such contractors when they are needed could
have a material adverse effect on the Company's business, financial condition
and results of operations.     
 
CONTROL BY OFFICERS, DIRECTORS AND THAYER
   
  Upon completion of this offering, the Company's officers and directors, and
their affiliates, in the aggregate, will have voting control over
approximately 73% of the Company's outstanding Common Stock. In particular,
Thayer and its affiliates will have voting control over approximately 60% of
the Company's outstanding Common Stock. As a result, these stockholders will
be able to control all matters requiring stockholder approval, including the
election of directors and approval of significant corporate transactions. The
voting power of Thayer and the Company's officers and directors under certain
circumstances could have the effect of preventing or delaying a change in
control of the Company. See "Principal and Selling Stockholders."     
 
ANTI-TAKEOVER EFFECT OF CERTAIN PROVISIONS
   
  The Company's Second Amended and Restated Certificate of Incorporation and
Second Amended and Restated Bylaws contain certain provisions that may have
the effect of discouraging a third party from making an acquisition proposal
for the Company. Such provisions could limit the price that investors might be
willing to pay in the future for shares of the Company's Common Stock. For
example, the Board of Directors is authorized to issue, without stockholder
approval, up to 25,000,000 shares of preferred stock, $.01 par value, of the
Company (the "Preferred Stock") with voting, conversion and other rights and
preferences that may be superior to the Common Stock and that could adversely
affect the voting power or other rights of the holders of Common Stock. The
issuance of Preferred Stock or of rights to purchase Preferred Stock could be
used to discourage an unsolicited acquisition proposal. Other provisions
impose various procedural and other requirements that could make it more
difficult for shareholders to effect certain corporate actions. In addition,
the Company's Board of Directors is divided into three classes, the members of
each of which will serve for a staggered three-year term, which may make it
more difficult for a third party to gain control of the Company's Board of
Directors. Certain provisions of the Cooperation Agreement with SAG may also
have the effect of discouraging a third party from making an acquisition
proposal for the Company. See "Company Background" and "Description of Capital
Stock--Certain Provisions of Delaware Law, the Certificate of Incorporation
and the Bylaws."     
 
                                      13
<PAGE>
 
NO PRIOR MARKET FOR COMMON STOCK AND POSSIBLE VOLATILITY OF COMMON STOCK PRICE
 
  Prior to this offering, there has been no public market for the Common
Stock, and there can be no assurance that an active trading market will
develop following this offering. The initial public offering price will be
determined through negotiations among the Company and the Underwriters and may
not be indicative of the market price of the Common Stock after the completion
of this offering. See "Underwriting" for factors to be considered in
determining the initial public offering price. The market price for the Common
Stock after this offering may be volatile and may be affected by a number of
factors, including the announcement of new products, product enhancements or
services by the Company or its competitors, quarterly variations in the
Company's or its competitors' results of operations, changes in earnings
estimates or recommendations by securities analysts, developments in the
Company's industry, general market conditions and other factors, including
factors unrelated to the operating performance of the Company or its
competitors. In addition, stock prices for many companies in the technology
sector have experienced wide fluctuations that often have been unrelated to
the operating performance of such companies. Such factors and fluctuations, as
well as general economic, political and market conditions, such as recessions,
may materially adversely affect the market price of the Company's Common
Stock.
 
SHARES ELIGIBLE FOR FUTURE SALE
   
  Upon completion of this offering, the Company will have outstanding
28,937,500 shares of Common Stock. Of these shares, the 7,700,000 shares
offered hereby will be freely tradable without restriction in the public
market. An additional 2,750,000 shares will be eligible for sale beginning 90
days after the date of this Prospectus (all of which will be subject to 180-
day lock-up agreements between certain shareholders and the Representatives of
the Underwriters), and 18,487,500 shares will be eligible for sale beginning
March 31, 1998 (all of which will be subject to 180-day lock-up agreements).
BancAmerica Robertson Stephens may, in its sole discretion and at any time
without notice, release all or any portion of the securities subject to the
lockup agreements. In addition, the Company intends to file registration
statements on Form S-8 under the Securities Act of 1933, as amended (the
"Securities Act"), as soon as practicable after consummation of this offering,
in order to register all shares of Common Stock issuable or reserved for
issuance under the Stock Option Plan. Sales of substantial amounts of Common
Stock or the availability of such shares for sale could adversely affect
prevailing market prices of the Common Stock. See "Shares Eligible for Future
Sale" and "Underwriting."     
 
DILUTIVE EFFECT OF THE OFFERING
   
  Purchasers of Common Stock in this offering will experience immediate and
significant dilution of approximately $11.01 in the net tangible book value
per share of the Common Stock so purchased, based on an assumed initial public
offering price of $13.00 per share. This will result in the existing
stockholders of the Company realizing an immediate accretion in the net
tangible book value of their investment. See "Dilution."     
 
DIVIDENDS
 
  The Company does not anticipate paying any cash dividends on its Common
Stock in the foreseeable future. See "Dividend Policy."
 
                                      14

                              COMPANY BACKGROUND
 
  In February 1981, the Company was incorporated as a Delaware corporation and
established as a holding company for Software AG Americas, Inc. Since 1973,
Software AG Americas, Inc. has primarily licensed and serviced SAG products in
the United States and other countries through a series of licensing agreements
with SAG. In June 1981, the Company sold approximately 30% of its outstanding
common stock in an initial public offering. In 1988, SAG purchased all of the
outstanding stock of the Company, thereby acquiring control of the Company.
   
  On March 31, 1997, the Company consummated the Recapitalization, pursuant to
which the senior management of the Company and Thayer acquired approximately
89% of the outstanding Common Stock of the Company. See "Certain Relationships
and Transactions." The Company believes that the Recapitalization provides
several significant benefits to the Company, such as access to growth and
development capital, equity ownership incentives for management and other key
employees, and the opportunity and ability to pursue acquisitions and internal
product development.     
   
  Immediately prior to the Recapitalization, the Company and SAG entered into
the Cooperation Agreement which generally (i) provides the Company the
exclusive and perpetual right to license and service in North America, South
America, Japan and Israel (the "Territory") both existing and future products
developed or acquired by SAG and (ii) provides SAG the exclusive and perpetual
right to license and service outside the Territory both existing and future
products developed or acquired by the Company. Each of the Company and SAG
must pay the other 24% of the net revenues derived from such licenses. This
24% royalty rate is fixed for 20 years. Except under certain circumstances,
the Company's minimum annual royalty payment to SAG through the year 2000 must
equal at least $21 million. In 1994, 1995 and 1996, the Company's aggregate
royalty payments to SAG were approximately $29.0 million, $23.9 million and
$26.1 million, respectively. See "Certain Relationships and Transactions." The
Company anticipates that the Cooperation Agreement and SAG's equity interest
in the Company will promote close collaboration between the Company and SAG.
See "Principal and Selling Stockholders."     
 
  The Cooperation Agreement contains certain safeguards to ensure that the
Company and SAG are able to continue to exercise their respective rights to
license and service each other's products in their respective territories.
These safeguards include rights of first refusal with respect to transfers of
proprietary rights to third parties and restrictions on SAG from competing
against the Company in the Territory and on the Company from competing against
SAG outside the Territory. The Cooperation Agreement also prohibits either
party from consummating a change of control unless such party's successor
agrees to be bound by the terms of the Cooperation Agreement with respect to
all existing products of such party and future products that are materially
derived therefrom. In addition, SAG is precluded from consummating a change of
control unless its successor agrees to continue supporting the research and
development of SAG's then existing and planned products for two years
following the change in control. The Company is precluded from consummating a
change in control in which certain specified entities would be its successor
unless such entities agree to pay the Company's minimum annual royalty
payments to SAG until the later of December 31, 2000 or two years following
the change in control.
   
  On September 30, 1997, the Company acquired R.D. Nickel, a software company
that develops, licenses and supports a family of application development
products, including CONSTRUCT and CONSTRUCT Spectrum. Additionally, R.D.
Nickel has served as the exclusive distributor of the Company's products in
Canada since 1973. In the year ended November 30, 1996 and for the ten months
ended September 30, 1997, R.D. Nickel had revenues of US$13.6 million and
US$12.6 million, respectively. The Company purchased R.D. Nickel for Cdn$14.0
million (approximately US$10.1 million), consisting of a Cdn$7.0 million
promissory note and Cdn$7.0 million in cash. The Company is required to repay
the promissory note with proceeds from this offering. Upon consummation of
this offering, the Company will owe an additional payment of Cdn$500,000
(approximately US$360,000) in connection with the acquisition, which also will
be paid with proceeds from this offering. In connection with this acquisition,
in the quarter ended September 30, 1997, the Company recorded approximately
US$4.9 million of goodwill, which will be amortized on a straight-line basis
over 10 years, and took a one-time charge of approximately US$6.1 million
associated with the purchase of incomplete or in-process research and
development.

                                USE OF PROCEEDS
 
  The net proceeds to the Company from the sale of the 4,600,000 shares of
Common Stock offered by the Company hereby are estimated to be approximately
$54.5 million, assuming an initial public offering price of $13.00 per share
and after deducting the underwriting discounts and commissions and estimated
offering expenses payable by the Company. The Company will not receive any
proceeds from the sale of Common Stock by the Selling Stockholders.
   
  The principal purposes of this offering are to increase the Company's equity
capital, to establish a public market for the Company's Common Stock, to
provide enhanced equity incentives to attract and retain key employees, to
increase the Company's visibility in its markets, to facilitate future access
to public capital markets and to obtain additional working capital. The
Company will use a portion of the net proceeds to repay a promissory note
issued by the Company in connection with the acquisition of R.D. Nickel. This
note bears simple interest at a rate of 9% per annum and will have an
outstanding balance of principal and accrued interest at November 15, 1997 of
approximately Cdn$7.1 million (US$5.1 million). It has a stated maturity date
of September 30, 1999, but requires prepayment upon consummation of this
offering. In accordance with the terms of the acquisition of R.D. Nickel, upon
consummation of this offering, the Company will owe an additional payment of
Cdn$500,000 (approximately US$360,000), which will be paid from the net
proceeds of this offering. See "Company Background."     
   
  The remainder of the net proceeds of this offering will be used for working
capital and other general corporate purposes, including financing product
development and augmenting the Company's professional services business. A
portion of the net proceeds may also be used to fund acquisitions of
complementary businesses, products or technologies. The Company is not
currently a party to any agreements, understandings or negotiations with
respect to any material acquisitions. Pending such uses, the Company intends
to invest the net proceeds in short-term, interest bearing, investment grade
securities.     
 
                                DIVIDEND POLICY
   
  In 1995 and 1996, while a wholly owned subsidiary of SAG, the Company paid
aggregate cash dividends to SAG of $1.7 million and $9.0 million,
respectively. The Company does not anticipate paying any cash dividends on its
Common Stock in the foreseeable future. Certain of the Company's lines of
credit have the effect of restricting the ability of the Company to pay cash
dividends. See "Management's Discussion and Analysis of Financial Condition
and Results of Operations--Liquidity and Capital Resources" and Note 6 of
Notes to Consolidated Financial Statements.

  The following table sets forth as of September 30, 1997 the capitalization
and short term debt of the Company on an actual basis and on an as adjusted
basis to give effect to the sale by the Company of the 4,600,000 shares of
Common Stock offered by it hereby at an assumed initial public offering price
of $13.00 per share and the application of the net proceeds therefrom. See
"Use of Proceeds." This table should be read in conjunction with "Management's

                                   DILUTION
   
  The net tangible book value of the Company as of September 30, 1997 was $3.0
million, or $0.12 per share of outstanding Common Stock. Net tangible book
value per share is equal to the Company's total tangible assets less total
liabilities, divided by the total number of shares of Common Stock
outstanding. After giving effect to the sale of the 4,600,000 shares of Common
Stock offered by the Company hereby at an assumed initial public offering
price of $13.00 per share and the receipt of the estimated net proceeds
therefrom, the adjusted net tangible book value of the Company as of September
30, 1997 would have been $57.5 million, or $1.99 per share. This represents an
immediate increase in net tangible book value of $1.87 per share to existing
stockholders and an immediate dilution of $11.01 per share to investors
purchasing shares of Common Stock in this offering. The following table
illustrates this per share dilution:

(1) Sales by the Selling Stockholders in this offering will cause the number
    of shares of Common Stock held by existing stockholders to be reduced to
    21,237,500 shares, or 73.4% of the total number of shares of Common Stock
    to be outstanding after this offering (20,660,000 shares, or 68.7%, if the
    Underwriters' over-allotment option is exercised in full), and will
    increase the number of shares of Common Stock held by the new investors to
    7,700,000 shares, or 26.6% of the total number of shares of Common Stock
    to be outstanding immediately after this offering (8,855,000 shares, or
    29.4%, if the Underwriters' over-allotment option is exercised in full).
    See "Principal and Selling Stockholders."     
   
  The calculation of net tangible book value per share and the other
computations above assume no exercise of outstanding options under the Stock
Option Plan. As of October 15, 1997, 4,947,525 shares of Common Stock were
issuable upon exercise of outstanding stock options at a weighted average
exercise price of $4.90 per share. To the extent the outstanding options are
exercised, or additional stock options are granted and exercised at a price
per share below the initial public offering price in the future, there will be
further dilution to new investors. See "Management--Stock Option Plan."

                     MANAGEMENT'S DISCUSSION AND ANALYSIS
               OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS
 
  The following discussion contains forward-looking statements which involve
risks and uncertainties. The Company's actual results may differ significantly
from the results discussed in the forward-looking statements. Factors that
might cause such a difference include, but are not limited to, those discussed
in "Risk Factors."
 
OVERVIEW
 
  The Company is an enterprise solutions company that provides robust software
products and related professional services to large organizations with complex
computing requirements. The Company's revenues are primarily derived from
license fees for the use of software products, fees for maintenance related to
those products and fees for professional services. Since 1973, the Company has
primarily licensed and serviced SAG products in the United States and other
countries through a series of licensing agreements with SAG. In 1981, the
Company sold approximately 30% of its outstanding Common Stock in an initial
public offering. In 1988, SAG purchased all of the outstanding Common Stock of
the Company, thereby acquiring control of the Company.
 
  On March 31, 1997, the Company consummated the Recapitalization, pursuant to
which the senior management of the Company and Thayer acquired approximately
89% of the outstanding Common Stock of the Company. The Company believes the
Recapitalization provides several significant benefits to the Company such as
access to growth and development capital, equity ownership incentives for
management and other key employees, and the opportunity and ability to pursue
acquisitions and internal product development. See "Company Background" and
"Certain Relationships and Transactions."
 
  Prior to the Recapitalization, the Company's management team was constrained
by SAG in its ability to develop new products, license third-party software,
retain capital for expansion and make acquisitions of companies, products or
technologies. The Company's relatively low software product development
expenditures resulted, in part, from these constraints. Management has
undertaken several strategic initiatives since the Recapitalization to
increase revenue growth and profitability, including building a product
development organization, developing a product and professional services
offering that addresses the year 2000 problem and acquiring R.D. Nickel.
 
  Software license fees are generated through the licensing of enterprise
development and enterprise enablement products. Enterprise development
products include ADABAS, a high-performance data management system, and
NATURAL, a 4GL programming language. Enterprise enablement software products
include ENTIRE, a family of middleware products; INSIGHT 2000 Tool Kit, a
software product that addresses the year 2000 problem; and a number of Company
and third-party products which address the data warehouse and Web enablement
markets. The Company recognizes license fee revenues in accordance with
Statement of Position 91-1, "Software Revenue Recognition" issued by the
American Institute of Certified Public Accountants. Software license fee
revenues are recognized upon shipment of the software if the software is not
subject to customer acceptance or significant post-delivery obligations. If
the license is subject to customer acceptance or significant post-delivery
obligations, the recognition of license fees is deferred until customer
acceptance or the significant post-delivery obligations have been met.
 
  The Company also provides maintenance and support services to its customers.
Such maintenance services are typically provided in accordance with annual
agreements, with maintenance fees charged as a percentage of current software
license fees. Maintenance fees are recognized ratably over the term of the
agreement.
   
  Software license and maintenance fees are derived from both direct and
indirect channels. In North America, a direct sales and support structure is
utilized through the Company's wholly     
 
                                      21

owned subsidiaries. In the remainder of the Territory, exclusive distributors
sell the Company's products and provide maintenance support and pay the
Company a royalty on the revenues derived therefrom. The Company has
historically derived the majority of its revenues from sales within the United
States. Sales outside of the United States represented 13.9%, 16.2% and 17.8%
of the Company's total revenues in 1995, 1996 and the nine months ended
September 30, 1997, respectively.     
 
  The Company also generates revenues through the provision of professional
services associated with the implementation and deployment of the Company's
enterprise development and enterprise enablement products and through
educational services. The Company recognizes revenue from professional
services as such services are performed. The Company's professional services
offerings include consulting, software integration, system implementation,
large project management and year 2000 analysis and remediation. These
services are delivered on either a time and materials basis or a fixed price
basis. The Company is currently moving away from fixed price professional
services contracts. However, year 2000 business will continue to be conducted
using primarily fixed price contracts based on the number of lines of code
analyzed or remediated, as opposed to a specific and defined set of
deliverables as is the case in traditional fixed price contracts.
   
  The Company offers its products and professional services to certain
customers under Enterprise License Agreements ("ELAs"). ELAs are typically
long term contracts of three to five years which include the provision of
software products, professional services and maintenance support. Revenues
from software licenses sold as part of an ELA are recognized as revenue when
such products are shipped and revenue from professional services and
maintenance support are recognized as provided. As of September 30, 1997, 106
of the Company's customers had entered into ELAs with the Company.

NINE MONTHS ENDED SEPTEMBER 30, 1997 AND 1996     
 
 Revenues
   
  Total Revenues. The Company's revenues are currently derived from fees from
licensing the Company's software products, fees for providing maintenance to
customers which have licensed the Company's software products and fees from
professional services. The Company's total revenues were $124.3 million and
$110.5 million for the nine months ended September 30, 1997 and 1996,
respectively, representing an increase of 12.5%.     
   
  Software License Fees. The Company's software license fees are derived
primarily from the licensing of the Company's enterprise development and
enterprise enablement products. Software license fees were $40.1 million and
$31.8 million for the nine months ended September 30, 1997 and 1996,
respectively, representing an increase of 26.1%. This increase was primarily
attributable to the reorganization of the direct sales force at the beginning
of 1997 into three groups, with one group focused on software products,
another on professional services and a third on the Year 2000 Program. As a
result of this reorganization, the Company has experienced increased
acceptance of ELAs by its customer base. For the nine months ended September
30, 1997, the Company has entered into 30 new ELAs, compared to 14 new ELAs
for the nine months ended September 30, 1996.     
   
  Maintenance Fees. The Company's maintenance fees are derived primarily from
providing technical support to customers which have licensed the Company's
enterprise development and enterprise enablement products. Maintenance is
available in various levels of support and priced as a percentage of the
software license fees. The most commonly contracted level is priced at 18% of
the applicable license fee at the time of renewal. Software customers are not
required to renew their maintenance agreements and renewals can be expected
only if the customer continues to use the licensed product. Maintenance fees
were $53.3 million and $51.8 million for the nine months ended September 30,
1997 and 1996, respectively, representing an increase of 2.9%. This increase
was due primarily to the effect of price increases, combined with an increase
in the maintenance base from the sale of new software licenses.     
   
  Professional Services Fees. The Company's professional services fees are
derived primarily from work performed by the Company on behalf of customers
who have licensed the Company's software products. Professional services fees
were $31.0 million and $27.0 million for the nine months ended September 30,
1997 and 1996, respectively, representing an increase of 14.8%. This increase
was primarily attributable to the Company's Year 2000 Program, which began in
1997 and contributed $3.7 million of professional services fees in the nine
months ended September 30, 1997.     
 
 Cost of Revenues
   
  Software License. Software license costs consist primarily of royalties paid
to third parties. Software license costs were $12.6 million and $8.5 million
for the nine months ended September 30, 1997 and 1996, respectively,
representing 31.5% and 26.9% of software license fees for each respective
period. The increase in dollar amount was due primarily to an increase in
sales volume. The percentage increase was primarily due to a shift in product
mix since royalty rates on third-party products vary from 24% to 40%.     
   
  Maintenance. Maintenance costs consist of royalties paid to third parties,
the costs of providing customer support and the distribution costs of new
releases. Maintenance costs were $20.8 million and $19.3 million for the nine
months ended September 30, 1997 and 1996, respectively, representing 39.1% and
37.2% of maintenance fees for each respective period. This increase was
primarily attributable to the addition of staff to support new enterprise
enablement products.     
 
                                      24
<PAGE>
 
   
  Professional Services. Professional services costs consist of labor and
related overhead costs for the people performing the services. Such costs
include costs for project management, quality control, proposal writing and
project review. Professional services costs were $27.2 million and $25.9
million for the nine months ended September 30, 1997 and 1996, respectively,
representing 87.7% and 95.8% of professional services fees for each respective
period. The improvement in margin was primarily attributable to improved
performance on fixed price contracts combined with improved utilization of
resources. Both of these improvements were derived from process changes
initiated in late 1995 that included enhanced infrastructure and tools for
project management, improved estimating and bidding processes and expanded
quality control procedures.     
 
 Operating Expenses
   
  Software Product Development. Software product development expenses include
all labor and overhead costs related to the development of software products
owned by the Company. Software product development costs were $0.6 million and
$1.4 million for the nine months ended September 30, 1997 and 1996,
respectively, representing 1.4% and 4.3% of software license fees for each
respective period. This decrease was the result of a sale, with transfer of
the applicable software product development costs, of one of the Company's
products in 1996 to a third party. Prior to the Recapitalization, the
Company's ability to invest in software product development was constrained.
The Company expects software product development expenses to increase in the
future as a percentage of software license fees.     
   
  Sales and Marketing. Sales and marketing expenses consist primarily of
employee salaries, benefits, commissions, and associated overhead costs, and
the cost of marketing programs, direct mailings, public relations, trade
shows, seminars, advertising and related communications. Sales and marketing
expenses were $27.9 million and $31.1 million for the nine months ended
September 30, 1997 and 1996, respectively, representing 22.4% and 28.2% of
total revenues for each respective period. This decrease was primarily
attributable to reductions in the direct sales force and related support
personnel, combined with reductions in marketing staff and programs. These
reductions were begun in 1995 and substantially implemented by June 1997. The
program reduced the number of direct sales, direct sales support and marketing
personnel from 252 at December 31, 1994 to 124 at September 30, 1997.     
   
  Administrative and General. Administrative and general expenses include
employee salaries and benefits for administration, executive, finance, legal,
human resources, data center, distribution and internal systems personnel and
associated overhead costs, as well as bad debt expenses and accounting and
legal expenses. Administrative and general expenses were $26.7 million and
$23.5 million for the nine months ended September 30, 1997 and 1996,
respectively, representing 21.5% and 21.2% of total revenues for each
respective period. The increased dollar amount was the result of increases in
personnel related expenses and infrastructure required to support an
independent company.     
   
  Write-off of Acquired In-Process Research and Development Costs. The write-
off of acquired in-process research and development costs was attributable to
certain of the products acquired in the acquisition of R. D. Nickel. See Note
4 of the Unaudited Condensed Consolidated Financial Statements.     
 
 
 Other
   
  Other Income and Expense, Net.  Other income and expense, net consists
primarily of interest earned on cash, cash equivalents, short term investments
and long term customer contracts carried by the Company, and miscellaneous
income, offset in part by interest expense associated with equipment
financing. Interest and investment income and expense, net was $2.4 million
and $2.2 million for the nine months ended September 30, 1997 and 1996,
respectively.     
   
  Income Tax Provision (Benefit). Income tax provision (benefit) was $4.5
million and $1.1 million for the nine months ended September 30, 1997 and
1996, respectively, resulting in effective tax rates of 41.6% (exclusive of
the write-off of acquired in-process research and development costs), and
37.4%, respectively. This increase in rate was primarily attributable to the
non-deductible expenses incurred as a result of the Recapitalization.

YEARS ENDED DECEMBER 31, 1996 AND 1995
 
 Revenues
 
  Total Revenues. The Company's total revenues were $156.8 million and $152.6
million in 1996 and 1995, respectively, representing an increase of 2.8%.
 
  Software License Fees. Software license fees were $52.2 million in 1996 and
$52.1 million in 1995, or 33.3% and 34.1% of total revenues for each
respective period.
 
  Maintenance Fees. Maintenance fees were $69.7 million in 1996 and $65.3
million in 1995, representing an increase of 6.7%. This increase was due
primarily to the effect of price increases combined with an increase in the
maintenance base from the sale of additional software licenses.
 
  Professional Services Fees. Professional services fees were $35.0 million in
1996 and $35.2 million in 1995, or 22.3% and 23.1% of total revenues for each
respective period. This minimal decline from 1995 to 1996 was the result of
actions taken in the latter part of 1995 to temporarily curb growth in the
professional services operation so that the Company could build a stronger
infrastructure and control process to support the rapid growth anticipated
from the Year 2000 Program. These actions were largely accomplished and
accounted for in the first half of 1996.
 
 Cost of Revenues
 
  Software License. Software license costs were $14.1 million in 1996 and
$15.2 million in 1995, representing 27.1% and 29.3% of software license fees
for each respective period. This decrease was primarily attributable to lower
third-party royalty rates associated with a slight shift in product mix.
   
  Maintenance. Maintenance costs were $25.9 million in 1996 and $23.5 million
in 1995, representing 37.1% and 36.0% of maintenance fees for each respective
period. The increase from 1995 to 1996 was primarily attributable to royalties
related to additional maintenance fees combined with a change in product mix.
    
  Professional Services. Professional services costs were $33.0 million in
1996 and $32.6 million in 1995, representing 94.3% and 92.6% of professional
services fees in each respective period. This increase was primarily
attributable to an increase in spending for infrastructure to support the
anticipated growth in the Year 2000 Program, partially offset by improved
margins on new projects.
 
 Operating Expenses
 
  Software Product Development. Software product development expenses were
$1.4 million in 1996 and $0.9 million in 1995, representing 2.6% and 1.7% of
software license fees, respectively. This increase was primarily attributable
to the employment of additional staff to develop and enhance the Company's
products.
 
  Sales and Marketing. Sales and marketing expenses were $48.7 million in 1996
and $52.5 million in 1995, representing 31.0% and 34.4% of total revenues,
respectively. This decrease in expenses was primarily attributable to
reductions made in 1995 to the direct sales force and to the direct support
personnel. As discussed previously, these reductions commenced in 1995 and
were substantially implemented by June 1997. The net effect of this reduction
during 1996 was to reduce the direct selling and support personnel from 131 at
December 31, 1995, to 98 at December 31, 1996, a net reduction of 25%.
   
  Administrative and General. Administrative and general expenses were $28.5
million in 1996 and $24.6 million in 1995, representing 18.2% and 16.2% of
total revenues, respectively. This increase was primarily attributable to
investments in computer equipment necessary to support anticipated growth of
the Year 2000 Program and severance payments made to the Company's former
chief executive officer.     
 
 Other
 
  Other Income and Expense, Net.  Other income and expense, net was $5.2
million in 1996 and $2.4 million in 1995. The difference was attributable to
interest received on $30.0 million in loans made to SAG in three stages over
1995 and 1996, combined with income received for the sale of the rights to one
of the Company's products. The loans were retired in March 1997 prior to the
Recapitalization.
 
                                      26
<PAGE>
 
  Income Tax Provision. Income tax provision was $4.3 million and $2.3 million
in 1996 and 1995, respectively, resulting in effective tax rates of 40.9% and
41.0%, respectively.
 
YEARS ENDED DECEMBER 31, 1995 AND 1994
 
 Revenues
 
  Total Revenues. The Company's total revenues were $152.6 million and $147.3
million in 1995 and 1994, respectively, representing an increase of 3.6%.
 
  Software License Fees. Software license fees were $52.1 million in 1995 and
$51.8 million in 1994, or 34.1% and 35.2% of total revenues for each
respective period.
 
  Maintenance Fees. Maintenance fees were $65.3 million in 1995 and $65.9
million in 1994, or 42.8% and 44.7% of total revenues for each respective
period. This decrease was primarily attributable to the transfer in 1994 of
the rights to license SAG products in Southeast Asia from the Company to SAG.
These rights accounted for 1994 maintenance revenue of $3.0 million. Adjusting
1994 for the impact of the loss of this territory and these rights in 1995,
maintenance revenues would have grown 3.8% from $62.9 million in 1994 to $65.3
million in 1995. The increase was due primarily to the effect of price
increases, combined with an increase in the maintenance base from the sale of
new software licenses.
 
  Professional Services Fees. Professional services fees were $35.2 million in
1995 and $29.6 million in 1994, representing an increase of 18.9%. This growth
was the result of an increased level of business in the customer base, aided
significantly by the award to the Company of several large contracts.
 
 Costs of Revenues
 
  Software Licenses. Software license costs were $15.2 million in 1995 and
$13.5 million in 1994, representing 29.3% and 26.1% of software license fees
for each respective period. This increase was primarily attributable to an
increase in third-party royalty rates associated with a shift in product mix.
   
  Maintenance. Maintenance costs were $23.5 million in 1995 and $29.8 million
in 1994, representing 36.0% and 45.3% of maintenance fees for each respective
period. This decrease from 1994 to 1995 was primarily attributable to
personnel cost reductions made as a result of the transfer of the Southeast
Asian territory to SAG, combined with a significant reduction in customer
support and product release personnel. This planned reduction was combined
with changes in support processes designed to improve productivity and
customer service.     
   
  Professional Services. Professional services costs were $32.6 million in
1995 and $26.5 million in 1994, representing 92.6% and 89.6% of professional
services fees in each respective period. This increase was primarily
attributable to losses on certain fixed price contracts. As a result, the
Company temporarily slowed the growth in professional services in order to
improve its infrastructure and control processes.     
 
 Operating Expenses
 
  Software Product Development. Software product development expenses were
$0.9 million in 1995 and $0.9 million in 1994, representing 1.7% of software
license fees in both years.
 
  Sales and Marketing. Sales and marketing expenses were $52.5 million in 1995
and $50.4 million in 1994, representing 34.4% and 34.2% of total revenues,
respectively. The increase in expenses was attributable to higher commissions
resulting from the growth in software licenses and professional services fees.
   
  Administrative and General. Administrative and general expenses were $24.6
million in 1995 and $25.2 million in 1994, representing 16.2% and 17.1% of
total revenues for each respective period.

 Other
 
   Other Income and Expense, Net. Other income and expense, net was $2.4
million in 1995 and $1.9 million in 1994.
 
  Income Tax Provision. Income tax provision was $2.3 million and $1.4 million
for 1995 and 1994, respectively, resulting in effective tax rates of 41.0% and
50.2%, respectively.

(1)The write-off of acquired in-process research and development costs for the
   quarter ended September 30, 1997 relates to the Company's acquisition of
   R.D. Nickel. Before deducting the nonrecurring write-off for this period,
   income from operations as a percentage of total revenues was 10.8% and net
   income as a percentage of total revenues was 6.0%.     
   
  As a result of the Recapitalization on March 31, 1997, the Company is no
longer a wholly owned subsidiary of SAG. Management has undertaken several
strategic initiatives since the Recapitalization to increase revenue growth
and profitability including building a product development organization,
developing a product and professional services offering that addresses the
year 2000 problem and acquiring R.D. Nickel. The revenue and profit
improvements from the first quarter to the second and third quarters may be
partially attributable to these changes, but there can be no assurance that
this trend will continue in future quarters. Due in part to these initiatives,
the Company expects that product development costs as a percentage of software
license fees will increase and that administrative and general expenses as a
percentage of total revenues will decrease.     
   
  The Company's results of operations have historically fluctuated on a
quarterly basis and are expected to be subject to quarterly fluctuations in
the future. The Company's software license fees have tended to increase
through each successive quarter of the year, with software license fees in the
first quarter of a year being lower than those in the immediately preceding
fourth quarter. Third quarter results have been favorably affected by
increased end of the year spending by the Company's government customers.
Fourth quarter results benefit from those customers who operate on a calendar
year basis, combined with the Company's sales compensation plans which include
incentives for achieving annual targets. In addition, due to the
reorganization of the sales force and the increase in the number of ELAs, the
Company's historic trend of third and fourth quarter revenues that are
significantly larger than previous first and second quarter revenues may not
continue. The Company typically does not have a material backlog of unfilled
orders, and revenues in any quarter are substantially dependent on orders
booked in that quarter.     
   
  Maintenance fees generally have not fluctuated on a quarterly basis to the
same degree as software license fees due to the large percentage of
maintenance fees generated from renewals of annual maintenance contracts which
are recognized ratably over the contract period.     
 
  Revenues from professional services are influenced by the number of
personnel providing such services, the utilization rates of such personnel and
the number of billable days in a quarter. Other factors being equal,
 
                                      29

a quarter ending December 31 will generally reflect lower professional
services fees than other quarters due to the relatively large number of
holidays falling in that quarter. In addition, the completion or commencement
of significant professional services projects may affect the revenues from
professional services in a particular quarter.
          
  Software license costs have varied from period to period and can be expected
to fluctuate in the future primarily due to shifts in product mix since
royalty rates on third party products vary from 24% to 40%.     
   
  Historically, sales and marketing expenses have varied from quarter to
quarter in absolute dollar terms and as a percentage of revenues, as a result
of the size and timing of marketing programs. A significant portion of
marketing program costs are variable in nature and subject to management
discretion as to their timing and amount.     
   
  The Company's quarterly operating results may continue to fluctuate due to
numerous factors, including the demand for the Company's products and
services, the timing and cost of new product and service introductions and
product enhancements by the Company or its competitors, changes in the mix of
products and services sold by the Company and in the mix of sales by
distribution channels, commencement or conclusion of significant service
contracts, timing of any acquisitions and associated costs, the size, timing
and terms of customer orders, including delays in significant orders, changes
in pricing policies by the Company or its competitors, the timing of
collection of accounts receivable, changes in foreign currency exchange rates,
competitive conditions in the industry and general economic conditions. The
Company's expenses are generally fixed and do not vary significantly in the
short term with revenues. As a result, operating and net income in a given
quarter may be disproportionately affected by a reduction in revenues. See
"Risk Factors--Potential Fluctuations in Quarterly Performance."     
 
LIQUIDITY AND CAPITAL RESOURCES
   
  Since 1988, when the Company became a wholly owned subsidiary of SAG, the
Company has financed its operations principally through cash flow from
operating activities. In order to meet its short term cash needs and to pay
dividends to SAG, in 1992 the Company began to periodically sell long term
customer receivable contracts. Sales of long term customer receivable
contracts increased in subsequent years in order to meet SAG's directives and
in connection with the Recapitalization. Since the Recapitalization, the
Company has sold $27.9 million of long term customer receivable contracts,
primarily to fund the repayment of certain obligations incurred in connection
with the Recapitalization and to fund the acquisition of R.D. Nickel. The
Company does not expect to sell additional long term customer receivable
contracts in the foreseeable future.     
   
  Investing activities used net cash of $3.1 million, $23.8 million, $4.3
million and $27.1 million during 1994, 1995, 1996 and the nine months ended
September 30, 1997, respectively, primarily to fund capital expenditures
needed to support expansion of the Company's business, to provide loans to SAG
and as consideration for the Cooperation Agreement. Financing activities used
net cash of $4.5 million, $4.8 million, $9.0 million and $2.2 million during
1994, 1995, 1996 and the nine months ended September 30, 1997, respectively,
primarily for the repayment of long term obligations, the payment of
dividends, and the repurchase of Common Stock.     
   
  The Company has no long term debt, and as of September 30, 1997 had
approximately $18.3 million in cash and investments. The Company has two
accounts receivable lines of credit. Under these lines, the Company may sell
long term receivable contracts. These transactions are treated as sales by the
Company as the economic interest in the contract is transferred to the buyer.
The Company's accounts receivable days sales outstanding at September 30, 1997
was 60.     
   
  The Company's international distributors report and pay in U.S. dollars. In
addition, royalties reported and paid by the Company to SAG under the
Cooperation Agreement are in U.S. dollars. The Company's Mexican operations
commenced in 1996 and represented less than 3% of total revenues in 1996. The

Company, therefore, has not to date engaged in foreign currency hedging
transactions. In the event of significant growth in international operations,
the Company may enter into hedging transactions.
 
  The Company traditionally leases all major equipment, and has no investment
in inventory or facilities other than leasehold improvements.
 
  The Company believes that the proceeds from the sale of the Common Stock
offered hereby, together with its existing cash balances, funds generated from
operations and available accounts receivable lines of credit will be
sufficient to finance the Company's operations for at least the next twelve
months. Although operating activities may provide cash in certain periods, to
the extent the Company grows in the future, its operating and investing
activities may use such cash. There can be no assurances that any necessary
additional financing will be available to the Company on commercially
reasonable terms.

INDUSTRY BACKGROUND
   
  Worldwide, large business and governmental organizations rely on large-scale
computer applications to help manage their businesses. These applications,
many of which are mission-critical, contain the core knowledge and processes
that support the major operations of these organizations. Examples of such
applications include customer billing systems, financial accounting systems
and inventory management systems.     
 
  Mainframes are the predominant computing platform for running mission-
critical applications because they provide the high levels of reliability,
scaleability, security, manageability and control required by such
applications. Recently, with the proliferation of intranets, the growth of the
Internet and the decreasing cost of operating mainframe systems, mainframes
have gained increased importance as servers capable of managing and providing
widespread access to corporate data. Large organizations are also seeking to
leverage investments in existing systems by integrating their mainframe
systems with distributed computing environments. International Data
Corporation estimated that worldwide software revenue for the mainframe
segment exceeded $26 billion in 1996.
 
                                      32
<PAGE>
 
  Organizations must continually build, modify and maintain their information
systems in order to respond to competitive pressures, regulatory changes and
technological advances. For example, many organizations have initiated
significant modifications of their information systems to address the
increasing demands of management for more information for decision making and
the needs of customers and suppliers for greater access to information.
Organizations are constantly updating their information systems to exploit
advances in database management, communication and software technologies and
to maximize the return on their investments in existing systems. In addition,
the size and complexity of the year 2000 problem, a problem expected in the
year 2000 when applications with two-digit entries in the date code field will
need to accept four-digit entries to distinguish twenty-first century dates
from twentieth century dates, has created significant demand for technology
and professional services that address that problem.
   
  The need to continually adapt information systems is placing increased
demands on organizations. Already suffering from a shortage of qualified
technical professionals, information technology ("IT") organizations are
required to work more productively, to distribute information to users more
quickly and to preserve the investments that have already been made in
computing assets. The Company estimates that there are over one billion lines
of NATURAL code in the United States alone. IT organizations are seeking to
integrate new technologies into their mainframe systems to avoid the downtime,
expense and risks involved in replacing these systems and the applications
running on these systems. In many cases, IT organizations lack the resources
and expertise required to cost-effectively implement and maintain distributed
computing systems. The inability of these organizations to fully utilize
available technology, together with the limited functionality of many existing
processes and tools, has increased demand for integrated software development
products and professional services.     
 
  As a result, organizations are increasingly seeking to achieve the
reliability, scaleability and interoperability of legacy systems while
leveraging the speed, cost effectiveness and flexibility of new technologies.
The Company believes that organizations are meeting this challenge by working
with vendors that: (i) provide enterprise level performance; (ii) enhance and
extend existing computing investments; and (iii) provide a comprehensive
solution of products, professional services and support.
 
THE COMPANY'S SOLUTIONS
 
  Over its 24 year history, the Company has developed significant expertise in
addressing the needs of large, complex computing environments at the
enterprise level. The Company's solutions enable its customers to leverage
their investments in existing information systems and personnel, and to
enhance and expand these systems to meet the changing needs of the enterprise.
The Company believes its solutions provide the following benefits:
   
  Provide Enterprise Level Performance. The Company's solutions consist of
software products and related professional services that are used for the
development and enhancement of mission-critical enterprise applications. The
Company's products are used to build, maintain and extend business
applications that require reliability, scaleability and security, and
constitute the core technology behind mission-critical systems, such as those
used for customer billing, financial accounting and inventory management.     
 
  Enhance and Extend Existing Computing Investments. The Company's application
development and enablement products and related professional services allow
its customers to preserve their investments in mainframe systems by updating
and evolving their systems to meet changing business processes and needs.
 
     Enable New Enterprise Applications. The Company's products and
  professional services enable its customers to implement new enterprise
  applications that require access to existing corporate data wherever it
  resides. For example, the Company's software products and professional
  services expertise in building data warehousing applications allow IT
  organizations to create data warehouses that enable managers and knowledge
  workers to access and analyze corporate data previously unavailable to them
  for improved decision making.
 
 
                                      33
<PAGE>
 
    Extend Mission-Critical Applications to Distributed Computing
  Environments. The Company's solutions allow its customers to extend their
  mission-critical applications to distributed computing environments.
  Organizations can use the Company's products and professional services to
  connect their network-based architectures, including Internet and intranet-
  based systems, to their mainframe applications, providing improved access
  to corporate data. In this manner, existing applications need not be
  rewritten in order to extend them to the network or the Web, and the
  security, extensibility and scaleability of mainframe environments can be
  extended.
 
    Provide Solutions to the Year 2000 Problem. The Company's year 2000
  product, INSIGHT 2000 Tool Kit, and professional services assist its
  customers in resolving their year 2000 problem. Organizations can use the
  Company's year 2000 product and professional services to analyze the amount
  of remediation needed and to develop and implement a remediation and
  testing plan. In this manner, existing applications need not be abandoned
  or replaced upon the arrival of the year 2000.
 
  Provide a Comprehensive Solution of Products, Professional Services and
Support. The Company's solutions represent a comprehensive offering of
products, professional services and support from a single vendor. While many
"point" products exist in the form of connectivity tools, programming
languages and data management products, most are limited in their ability to
support the enterprise computing environment. The Company's extensive
experience in enterprise software and related professional services enables it
to address customers' mission-critical computing needs.
 
THE COMPANY'S STRATEGY
   
  The Company's strategy is to further leverage its current leadership
position in building enterprise applications and data access solutions for
large organizations by extending its product and professional services
offerings into the Web integration, data warehouse, middleware and year 2000
markets. Key elements of the Company's strategy include the following:     
   
  Enhance and Extend Product Offerings. The Company believes that a
substantial opportunity exists to provide software products and professional
services that assist organizations in building, modifying and maintaining
mainframe systems. To pursue this opportunity, the Company intends to enhance
its existing product offerings with added features and functionality. The
Company also intends to broaden its product offerings through internal product
development, additional licensed products from third parties and acquisitions.
In furtherance of this strategy, the Company recently acquired R.D. Nickel, a
software company with the CONSTRUCT family of application development products
which are used in conjunction with NATURAL. In addition, pursuant to the
Cooperation Agreement, the Company has an exclusive and perpetual right to
license in North America, South America, Japan and Israel (the "Territory")
any new products developed or acquired by SAG. The Company expects to continue
to benefit from SAG's product development efforts, which in 1996 totaled
approximately $56 million. See "Company Background."     
   
  Leverage Customer Base. Most of the Company's customers are large,
sophisticated organizations with complex information systems in dispersed,
heterogeneous computing environments. Over 1,500 customers in North America,
South America, Japan and Israel have licensed the Company's products or
purchased the Company's professional services since January 1996. Typically,
the IT budget of a customer of the Company substantially exceeds the annual
amount that customer spends with the Company. The Company believes it can
expand its share of its customers' IT budgets through increased and improved
product and professional services offerings.     
   
  Expand Professional Services Offerings. The Company believes that, due to
the strategic nature of its products, customers require the Company to provide
comprehensive professional services and support. The Company's strategy is to
expand its key professional services offerings, which are centered around
application development, data warehousing, Web integration and the year 2000
problem. The Company expects to hire additional consultants and to develop new
professional services offerings to meet its customers' evolving service needs.
The Company intends to expand its efforts to cross sell its professional
services to its product customers.     
 
                                      34
<PAGE>
 
   
  Leverage Distribution Channels. The Company directly and indirectly sells its
products in over 20 countries throughout the Territory through exclusive
distributors. Through the Cooperation Agreement with SAG, the Company has
access to SAG's distribution channels for the Company's products (other than
those licensed from SAG) in over 50 additional countries outside the Territory.
The Company intends to leverage this distribution channel by developing and
acquiring additional products for distribution by SAG.     
 
PRODUCTS AND SERVICES
 
  The following diagram depicts how the Company provides enterprise solutions
for its customers. The Company works at the highest level of IT organizations
to evaluate the overall needs of the enterprise and develop solutions that use
its products and professional services to effectively build, extend and enable
complex computing environments. Typically, the Company's solutions focus either
on building and deploying new mission-critical applications or enhancing and
extending existing business-critical applications through building data
warehouses and integrating with the Internet and intranets. The Company's
products and professional services allow its customers to leverage their
investments in existing information systems and personnel and to enhance and
expand these systems to meet the changing needs of their organizations.

SOFTWARE PRODUCT DEVELOPMENT
 
   Prior to the Recapitalization, the Company was a wholly owned subsidiary of
SAG and the Company's research and development efforts were directed by SAG.
The Company's software product development expenses were $0.9 million, $0.9
million and $1.4 million in 1994, 1995 and 1996, respectively.
   
   Since the Recapitalization, the Company has begun building its internal
product development group, which currently consists of 17 people, including 11
people added as a result of the acquisition of R.D. Nickel. The first product
resulting from the Company's recent internal product development efforts is
INSIGHT 2000 Tool Kit, which was released in September 1997. The Company
intends to continue expanding its product development group through additional
acquisitions and internal hiring.     
 
                                      38
<PAGE>
 
   
  Since the Cooperation Agreement provides the Company with an exclusive and
perpetual right to license in the Territory products developed by SAG, the
Company also expects to continue to benefit from SAG's product development
efforts. In 1996, SAG's product development costs were approximately $56
million. In September 1997, SAG released EntireX DCOM, the first product
resulting from SAG's strategic relationship with Microsoft.     
 
PRODUCT MAINTENANCE AND CUSTOMER SUPPORT
   
  The Company offers a wide range of product maintenance and customer support
services. The Company believes that its future success is dependent in part on
its ability to provide high levels of customer service in order to cultivate
advocacy by the Company's installed customer base. For the twelve months ended
September 30, 1997, approximately 96% of the Company's customers who were
eligible renewed at least one of their maintenance agreements. As of September
30, 1997, the Company had 119 employees devoted to its maintenance and
customer support services.     
 
  Customers may choose from three levels of service and support offerings:
basic, extended and custom, which are differentiated by service deliverables
and access to support persons. Some of these customer support services
include:
 
  .  Support during product proof-of-concept/trial
  .  Technical support 24 hours a day, seven days a week
  .  Customized support offerings
  .  Onsite installation and implementation
  .  Remote analysis
  .  Automated customer assistance and Web-based electronic services
 
CUSTOMERS AND MARKETS
   
  Over 1,500 customers in North America, South America, Japan and Israel have
licensed the Company's products or purchased the Company's professional
services since January 1996. These customers consist primarily of major
corporations, government agencies and educational institutions.     
 
  The following examples are representative of how customers use the Company's
products and professional services to build and enable enterprise level,
mission-critical applications for large organizations.
   
  Utility Business Services, Incorporated ("UBS"). An information service
bureau for water and wastewater companies, UBS needed to develop a new
customer information system to handle approximately 600,000 customer accounts
for 15 clients in New Jersey and New York. UBS decided to use the Company's
ADABAS, NATURAL and CONSTRUCT products and related services to develop a
system of enhanced services and applications that could be sold as an
independent software package to UBS's water utility clients handling their own
billing and information tracking. According to UBS, six of its programmers
developed the entire system in less than two years at a cost of approximately
$420,000 and the system resulted in savings of approximately $1.7 million
compared to projected COBOL development costs.     
   
  Federal Aviation Administration ("FAA"). In 1994, the FAA decided to migrate
its 400 mainframe COBOL financial and accounting modules to a client/server
windows architecture. To facilitate conversion of the online portion of the
system, the FAA used the Company's NATURAL Lightstorm product to create new
client/server components and the ADABAS product to manage data running in
Microsoft's Windows and Windows NT environments. According to the FAA, the new
system supports 1.7 million financial transactions each month, is utilized to
pay vendors an average of $27 million a day and is used daily by approximately
2,000 employees worldwide to process departmental accounting information.     
 
  City of New York. The City of New York was using an integrated, COBOL-based
system to process various business and commercial compliance activities, such
as license processing, inspections, cash management and consumer services. In
order to keep up with the changing operational requirements of a diverse user
community, the City of New York decided to switch to a new system using the
Company's
 
                                      39
<PAGE>
 
ADABAS and NATURAL products. According to the City of New York, the new system
produced a 60% decrease in license processing time and resulted in a 40%
increase in revenue collections.
 
  Pepsi-Cola General Bottlers Inc. ("PCGB"). In 1990, PCGB, then one of the
largest of Pepsi-Cola's bottlers, found that its systems were unable to handle
the company's volume of transactions. PCGB decided to replace its existing
systems with a system designed to centralize and support business processes in
a single set of programs and files. PCGB chose the Company's ADABAS product
and, in the process, developed its own enterprise methodology called Open
Batch Architecture which uses the Company's NATURAL, CONSTRUCT and ADABAS
products to streamline code development. According to PCGB, its new system for
domestic operations processes approximately 40 million commands daily.
   
  Vincent Metal Goods ("Vincent"). As a result of a merger in 1995, Vincent, a
large stainless steel and aluminum distributor, needed to consolidate and
convert its two existing computing systems into a single system for use by
Vincent's sales, warehouse and clerical employees located in 49 sites
throughout the United States. Vincent used the Company's professional services
offerings to develop, program and test new applications and selected a
mainframe system running on the Company's ADABAS and NATURAL products.
According to Vincent, its consolidated computer system is year 2000-ready and
was successfully completed three months ahead of schedule, within budget and
with minimal disruption to business functions and end-users.     
   
  The following is a representative list of some of the Company's customers
that produced revenues of at least $500,000 for the Company since January 1,
1996.

accounted for more than 10% of the Company's total revenues.     
 
SALES AND MARKETING
   
  The Company sells and markets its products through both direct and indirect
channels. Recently, the Company reorganized its sales organization into three
groups which focus separately on sales of ELAs, professional services and the
Year 2000 Program. The reorganization of the sales force has resulted in
significantly increased productivity per salesperson.     
 
                                      40
<PAGE>
 
   
  In North America, the Company sells and markets its products through a
direct channel that included over 120 people in 19 offices as of September 30,
1997. The Company sells its products in over 20 additional countries through
six exclusive distributorships in South America, Japan and Israel. In
addition, the Company has access to SAG's distribution channels for the
Company's products (other than those licensed from SAG) in over 50 countries
outside North America, South America, Japan and Israel. As of September 30,
1997, in North America, the Company directly sold its professional services
through 29 people. In addition, as of September 30, 1997, the Company had nine
people in the United States focused on selling its Year 2000 Program.     
   
  As of September 30, 1997, the Company's corporate marketing organization
supported the Company's sales and professional services channels through the
efforts of 35 professionals with expertise in product marketing, marketing
communications, database marketing, inside sales and strategic development.
The Company also has strategic marketing relationships with certain vendors of
computing products and services, including IBM, Microsoft, Digital Equipment
Corporation, Andersen Consulting and BDM.     
 
COMPETITION
 
  The markets for the Company's software products and professional services
are highly competitive and characterized by continual change and improvement
in technology. The Company provides products and professional services to
several markets within the computer industry and encounters a variety of
competitors within each such market. Many of the Company's competitors have
significantly greater financial, marketing and other competitive resources
than the Company. In addition, in certain markets in which the Company
competes, such as the year 2000 market, there are no significant barriers to
entry. Few of the Company's competitors compete in all of the same markets as
the Company.
 
  In the enterprise development markets, the Company's competitors with
respect to enterprise and departmental database management products include
IBM, Oracle, Informix, Sybase and Microsoft. In addition, the Company's 4GL
applications programming language, NATURAL, competes with offerings from both
large and small companies, including Oracle, Microsoft, IBM and Sterling
Software. In the enterprise enablement markets, the Company's products compete
in both the component/object and the message oriented segments of the
middleware market, where its competitors include IBM, Microsoft, and
Visigenic. The Company's competitors in the data warehousing segment of the
enablement markets include IBM, SAS, and PLATINUM and database vendors such as
Oracle, Sybase and Informix. In the market for year 2000 products and
professional services, the Company's competitors include Formal Systems,
Viasoft, BDM and EDS.
 
  The principal competitive factors affecting the markets for the Company's
product and professional services offerings include: (1) product
functionality, performance, reliability and ease of use, (2) quality of
technical support, training and consulting services, (3) responsiveness to
customer needs, (4) reputation, experience and financial stability and (5)
cost of ownership, including initial price and deployment costs as well as
ongoing maintenance costs. Due to the continued increase in new product
licenses and professional services revenues, the Company believes that it has
competed effectively in each of these areas. Nevertheless, current and
potential competitors may introduce new and better products, make strategic
acquisitions, or establish cooperative relationships among themselves or with
third parties, thereby increasing the ability of their products to address the
needs of the Company's current and prospective customers. There can be no
assurance that the Company will be able to compete successfully against
current and future competitors, and the failure to do so would have a material
adverse effect upon the Company's business, financial condition and results of
operations. See "Risk Factors--Competition."
 
PROPRIETARY RIGHTS
 
  The products sold by the Company consist of products developed by SAG (e.g.,
ADABAS, NATURAL and ENTIRE), products owned by other third parties which are
distributed by the Company (e.g.,
 
  
                                      41
<PAGE>
 
   
ESPERANT and iXpress) and products developed or acquired by the Company (i.e.,
INSIGHT 2000 Tool Kit, CONSTRUCT, CONSTRUCT Spectrum and CONSTRUCT Spectrum
SDK). For all of these products, the Company, if not the developer, is
contractually obligated to provide appropriate security measures to protect
the proprietary materials of SAG and other third parties against
misappropriation and illegal copying.     
   
  The Company treats all of the products that it distributes as proprietary
trade secrets and confidential information. It relies primarily upon a
combination of trade secret, copyright and trademark laws, its license
agreements with customers, and its internal security systems, confidentiality
procedures and employee agreements to maintain the security of its products.
The Company typically provides its products to users under nonexclusive,
nontransferable perpetual licenses which generally permit use of the licensed
software solely for internal operations on designated computers at specific
sites. Under certain circumstances, the Company makes available the source
code for its products under an escrow arrangement which restricts access to
and use of the source code. Although the Company takes steps to protect its
trade secrets and other proprietary rights, there can be no assurance that
misappropriation will not occur. In addition, the laws of some foreign
countries do not protect proprietary rights to the same extent as the laws of
the United States.     
 
  The Company seeks to protect its software, documentation and other written
materials under copyright law, and to assert trademark rights in its product
names. The Company has not sought to protect its products under patent laws,
though SAG and some third parties have patented, in the United States, Japan
and/or the European Union, certain of the products which the Company
distributes.
   
  Although the Company is not aware of any claims that its products,
trademarks or other proprietary rights infringe on the proprietary rights of
third parties, there can be no assurance that third parties will not assert
infringement claims against the Company in the future with respect to current
and future products or that any such assertion may not require the Company to
enter into royalty arrangements or result in costly litigation. See "Risk
Factors--Proprietary Technology."     
 
EMPLOYEES
   
  As of September 30, 1997, the Company employed 826 people, with 372 in
professional services and consulting, 124 in sales and marketing, 175 in
customer support, 14 in research and development and 141 in general and
administrative. As of September 30, 1997, the Company also utilized
approximately 106 individuals under independent contracts. None of the
Company's employees is represented by a labor union, and the Company has never
experienced any work stoppage. The Company considers its relations with its
employees to be good. The Company's success will depend in part on its
continued ability to attract and retain highly qualified personnel in a
competitive market for experienced software developers, professional services
staff and sales and marketing personnel. See "Risk Factors--Dependence on Key
Personnel; Need to Hire Additional Personnel."

  The Company's executive offices, principal marketing and data center
facility are located in approximately 170,000 square feet of space in a three

litigation arising in the ordinary course of business. As of the date of this

investment firm, from June 1993 to June 1995. From March 1989 until June 1993,
Dr. Stern served as Chief Executive Officer and Chairman of the Board of
Northern Telecom Limited. Dr. Stern currently serves as a director of The Dow
Chemical Company, The LTV Corporation and Whirlpool Corporation.     
 
  The Company's Second Amended and Restated Bylaws (the "Bylaws") provide for
the Company's Board of Directors to be comprised of six directors, and permit
the Board of Directors from time to time to increase or decrease the number of
directors. Pursuant to the terms of the Company's Second Amended and Restated
Certificate of Incorporation (the "Certificate of Incorporation"), upon the
consummation of this offering the directors will be divided into three
classes. One class will hold office initially for a term expiring at the
annual

meeting of the stockholders to be held in 1998, a second class will hold
office initially for a term expiring at the annual meeting of stockholders to
be held in 1999 and a third class will hold office initially for a term
expiring at the annual meeting of stockholders to be held in 2000. Each
director will hold office for the term to which he is elected and until his
successor is duly elected and qualified or until his earlier death,
resignation or removal. Mr. Gillis and Dr. Dauber will have terms expiring in
1998, Dr. Koenigs and Mr. Lucente will have terms expiring in 1999, and Mr.
Rickertsen and Dr. Stern will have terms expiring in 2000. At each annual
meeting of the stockholders of the Company, the successors to the class of
directors whose terms expire at such meeting will be elected to hold office
for a term expiring at the third succeeding annual meeting of stockholders
after their election.     
 
  Executive officers of the Company are elected by the Board of Directors on
an annual basis and serve until the first meeting of the Board of Directors
following the next annual meeting of stockholders following their election and
until their successors have been duly elected and qualified or until their
earlier death, resignation or removal. There are no family relationships among
any of the executive officers or directors of the Company.
 
COMMITTEES OF THE BOARD OF DIRECTORS
 
  In April 1997, the Board of Directors established an Audit Committee and a
Compensation Committee. The Audit Committee makes recommendations concerning
the engagement of independent public accountants, reviews with the Company's
independent public accountants the plans and results of the audit engagement,
approves professional services provided by the Company's independent public
accountants and reviews any recommendations made by the Company's auditors
regarding the Company's accounting methods and the adequacy of the Company's
internal accounting controls. The current members of the Audit Committee are
Messrs. Lucente and Rickertsen and Dr. Stern. The Compensation Committee
establishes general guidelines regarding the compensation of the officers and
executives of the Company and its subsidiaries, and determines the
compensation of the executive officers of the Company. The Compensation
Committee also administers the Stock Option Plan. The current members of the
Compensation Committee are Mr. Rickertsen and Drs. Stern and Dauber. The Audit
Committee and the Compensation Committee are comprised solely of directors who
are not officers or employees of the Company or any of its subsidiaries
("Independent Directors").
 
DIRECTOR COMPENSATION
 
  The Company's directors were not compensated during 1996 for any services
provided as directors and did not receive during such fiscal year any benefits
or other forms of compensation, cash or otherwise, from the Company for their
service as directors. The Company has no present plans to pay such benefits or
compensation to directors. The Company intends to reimburse directors for
certain out-of-pocket expenses incurred in connection with attendance at Board
of Directors and committee meetings.
   
  Each of Dr. Dauber and Mr. Lucente has received grants of nonstatutory stock
options under the Stock Option Plan to purchase 54,450 shares of Common Stock
at an exercise price equal to $1.47 per share. The options vest in equal
annual installments over a period of four years, commencing March 31, 1998.
The options become exercisable in full upon a change in control of the
Company. See "--Stock Option Plan."

  Messrs. Gillis, McCreery, Brigden, Daly, Gorley and Hill have received
grants of nonstatutory stock options under the Stock Option Plan to purchase
aggregate amounts of 2,472,800 and 1,017,289 shares of Common Stock at an
exercise price per share equal to $1.47 and $12.00, respectively. The options
granted to Messrs. Gillis and McCreery vest in equal annual installments over
a period of three years, and the options granted to Messrs. Brigden, Daly,
Gorley and Hill vest in equal annual installments over a period of four years.
The options become exercisable in full upon a change in control of the Company
and may be partially accelerated in connection with the executive officer's
termination of employment with the Company. See "--Stock Option Plan." Messrs.
Gillis, McCreery, Brigden, Daly, Gorley and Hill have also received grants of
nonstatutory stock options under the Stock Option Plan to purchase an
aggregate of 618,200 shares of Common Stock at an exercise price per share
equal to $9.60, which options are fully vested.     
 
STOCK OPTION PLAN
   
  In connection with the Recapitalization, which was consummated on March 31,
1997, the Company authorized the granting of stock options to purchase an
aggregate of 3,300,000 shares of Common Stock at an exercise price equal to
$1.47, the per share purchase price of the Recapitalization. On April 29,
1997, the Company adopted the Software AG Systems, Inc. 1997 Stock Option Plan
(the "Stock Option Plan"). The Stock Option Plan is intended to assist the
Company and its affiliates in attracting and retaining employees, directors,
consultants and advisors (collectively, the "Eligible Individuals") and to
promote the identification of their interests with those of the stockholders
of the Company. The Stock Option Plan permits a maximum of 6,875,000 shares of
Common Stock to be issued to Eligible Individuals pursuant to grants of stock
options. Unless sooner terminated by the Company's Board of Directors, the
Stock Option Plan will terminate on April 11, 2007. Options granted under the
Stock Option Plan may be either "incentive stock options" within the meaning
of Section 422 of the Internal Revenue Code of 1986, as amended (the "Code"),
or nonstatutory stock options. No option granted under the Stock Option Plan
is exerciseable after the tenth anniversary of the option's date of grant. The
Company has granted to Eligible Individuals nonstatutory stock options to
acquire an aggregate of 4,947,525 shares of Common Stock at a weighted average
exercise price of $4.90 per share.     
 
401(K) PLAN
   
  Software Americas provides a 401(k) plan (the "401(k) Plan") giving eligible
employees, including executive officers, the opportunity to accrue additional
income and to save for retirement on a before-tax basis. The 401(k) Plan is
qualified as a 401(k) plan under the Code. Software Americas employees are
generally eligible to participate in the plan after six months of full-time
employment. The 401(k) Plan provides that each participant may contribute up
to 15% of the participant's annual pre-tax compensation, but not more than the
annual maximum prescribed by law. The 401(k) Plan provides for Software
Americas to make matching contributions equal to 100% of pre-tax contributions
up to 5% of the participant's compensation for the payroll period or other
period over which contributions are made, as further limited by law. The
401(k) Plan also permits Software Americas to make discretionary employer
contributions, which if made, are allocated in proportion to the compensation
of each employee to the total compensation for the year of all employees. The
401(k) Plan does not allow contributions to exceed 6% of compensation.
Earnings under the 401(k) Plan accumulate tax free until distributed.     
 
DEFERRED COMPENSATION AGREEMENTS
 
  Software Americas has entered into deferred compensation agreements with
Messrs. Gillis, McCreery and Daly (the "Deferred Compensation Agreements").
Pursuant to these agreements, each of Messrs. Gillis, McCreery and Daly
annually receives a credit of $41,838, $46,000 and $24,000, respectively, to
his deferred compensation account plus an additional credit to such account
equal to 53%, 100% and 120%, respectively, of his bonus for such year. The
deferred compensation accounts earn interest at an annual rate of 6%. Under
the Deferred Compensation Agreements, no additional credits, other than
interest, will be made to any of the deferred compensation accounts after
December 31, 1998. The deferred compensation accounts of Messrs. McCreery and
Daly are fully vested. Mr. Gillis' deferred compensation account is currently
40% vested and will vest in full as of December 31, 1998. Except under certain
circumstances, upon termination of employment, each of Messrs. Gillis,
McCreery and Daly is entitled to receive from Software Americas payments
totaling the vested portion of his deferred compensation account.

SEVERANCE AGREEMENTS
   
  Mr. Gillis has entered into a memorandum of understanding with the Company
with respect to the termination of his employment as President and Chief
Executive Officer of the Company. Under this agreement, the Company is
required to pay Mr. Gillis a severance benefit equal to twelve months of his
then-current salary plus annual bonus ($460,000 minimum payment), and, for a
period not to exceed twelve months, to continue to make available his health
and other fringe benefits if (i) the Company terminates his employment other
than for cause or (ii) he resigns within ninety days of a substantial change
in his title or a substantial reduction in his compensation and benefits or
job responsibilities.     
   
  Each of Messrs. McCreery, Brigden and Daly has entered into a memorandum of
understanding with Software Americas with respect to the termination of his
employment on terms and conditions substantially similar to Mr. Gillis'
memorandum of understanding with the Company, provided, however, that (i) the
severance benefit due each such executive officer upon termination under his
respective memorandum of understanding is equal to twelve months of his then-
current salary plus a pro-rated bonus payment and (ii) no severance or other
benefits are due under these agreements if the executive officer resigns
within ninety days of a substantial reduction in his compensation and benefits
related to a company wide reduction or a substantial reduction in his job
responsibilities that is deemed to be in the best business interests of
Software Americas.     
   
  Pursuant to the terms of a Shareholders Agreement dated as of April 1, 1997,
each of Messrs. Gillis, McCreery, Brigden, Daly and Gorley has agreed that (i)
prior to the fifth anniversary of the termination of his employment with the
Company, he will not influence any employee to leave the Company and (ii)
prior to the third anniversary of the termination of his employment with the
Company (unless such termination is by the Company without cause), he will not
directly or indirectly compete with the Company by soliciting any of its
customers, clients or suppliers. Mr. Hill has agreed to similar restrictions
pursuant to a subscription agreement between Mr. Hill and the Company dated as
of August 22, 1997, as amended.     
 
COMPENSATION COMMITTEE INTERLOCKS AND INSIDER PARTICIPATION
   
  Prior to April 1997, the Company did not have a Compensation Committee or
other committee of the Board of Directors performing an equivalent function,
and the compensation of the Company's executive officers was determined by the
Company's Board of Directors. Since April 29, 1997, the Compensation Committee
of the Company's Board of Directors has been comprised of Mr. Rickertsen and
Drs. Stern and Dauber, each of whom is an Independent Director. Mr. Rickertsen
and Dr. Stern are members of TC Equity Partners, LLC, which is the sole
general partner of Thayer, a stockholder of the Company.

                    CERTAIN RELATIONSHIPS AND TRANSACTIONS
   
  At the closing of the Recapitalization, the senior management of the Company
and Thayer acquired approximately 89% of the outstanding voting equity of the
Company pursuant to an agreement among the Company, SAG, Thayer and the
following officers of the Company: Daniel F. Gillis, Harry K. McCreery, Gary
Hayes, James H. Daly, Derek M. Brigden and Thomas E. Gorley (collectively,
such individuals are referred to as the "Managers"). Prior to the
Recapitalization, SAG owned all of the Company's 27,500,000 outstanding shares
of Common Stock. In connection with the Recapitalization, the Company (i)
repurchased 24,750,000 shares of Common Stock from SAG for an aggregate
purchase price of 57,000,000 Deutsche Marks ($33.9 million) and (ii) issued
and sold 20,678,350 shares of Common Stock to Thayer and an aggregate of
771,650 shares of Common Stock to the Managers for an aggregate purchase price
of $31,526,820, or $1.47 per share. Of the Common Stock purchased by the
Managers, Messrs. Gillis and McCreery each purchased 204,050 shares and
Messrs. Hayes, Daly, Brigden and Gorley purchased 84,975, 108,625, 67,925 and
102,025 shares, respectively. After the Recapitalization, SAG retained
2,750,000 shares of Common Stock, representing approximately 11% of the
outstanding Common Stock. Dr. Erwin Koenigs, the Chairman of the Board and
Chief Executive Officer of SAG, is currently a director of the Company. As a
result of the Recapitalization, Thayer and the Managers respectively owned
85.4% and 3.2% of the outstanding Common Stock. Dr. Stern and Mr. Rickertsen,
directors of the Company, are members of TC Equity Partners, LLC, which is the
sole general partner of Thayer. In addition, Mr. Gillis is currently, and was
at the time of the Recapitalization, a director of the Company.     
   
  In connection with the Recapitalization, on March 31, 1997, Software
Americas borrowed $5,000,000 from Thayer under a short term note agreement for
working capital requirements. This note accrued interest at a simple rate
equal to 10% per annum and was repaid on April 11, 1997. In addition, Software
Americas paid to TC Management LLC ("TC Management") a financial advisory fee
of $840,000 in consideration for investment banking and advisory services
provided by TC Management in connection with the Recapitalization, and
reimbursed TC Management for its out-of-pocket expenses in connection with the
Recapitalization. On April 1, 1997, Software Americas also agreed to pay on a
quarterly basis an annual fee of $300,000 to TC Management for management and
consulting services to be provided by TC Management to Software Americas in
connection with the operation and conduct of Software Americas' business.
Through September 30, 1997, Software Americas has paid $150,000 of such fees.
TC Management is the managing agent of and provides management services to
Thayer. Dr. Stern and Mr. Rickertsen, directors of the Company, are members of
TC Management. In connection with the Recapitalization, Software Americas also
paid a one-time advisory fee of $250,000 to MLC Group, Inc., a wholly owned
operating subsidiary of MLC Holdings, Inc. Mr. Rickertsen, a director of the
Company, is a director of MLC Holdings, Inc.     
   
  Prior to the Recapitalization, the Company licensed and serviced SAG
products pursuant to a license agreement entered into by SAG and Software
Americas on January 1, 1995 (the "License Agreement"). The License Agreement
gave Software Americas the exclusive rights to license and service SAG
products in North America, South America, Japan and Israel, and gave SAG the
exclusive rights to license and service Software Americas products in all
other areas. Immediately prior to the Recapitalization, Software Americas and
SAG entered into a Cooperation Agreement dated March 31, 1997, which
terminated and superseded the License Agreement. The Cooperation Agreement
generally provides (i) Software Americas the exclusive and perpetual right to
license and service in North America, South America, Japan and Israel (the
"Territory") both existing and future products developed or acquired by SAG
and (ii) SAG the exclusive and perpetual right to license and service outside
the Territory both existing and future products developed or acquired by
Software Americas. Each of Software Americas and SAG must pay the other 24% of
the net revenues derived from such licenses. Except in certain circumstances,
Software Americas' minimum annual royalty payment to SAG through the year 2000
must at least equal $21 million. This 24% royalty rate is fixed for 20 years.
In 1994, 1995, 1996 and the first nine months of 1997, Software Americas'
royalty payments to SAG were approximately $29.0 million, $23.9 million, $26.1
million and $19.8 million, respectively. In the same periods,     
 
                                      50
<PAGE>
 
   
SAG's royalty payments to Software Americas were approximately $0.0, $0.3
million, $0.3 million and $0.5 million, respectively. As consideration for the
Cooperation Agreement, Software Americas paid SAG 38,000,000 Deutsche Marks
(approximately $22.6 million) on March 31, 1997. See "Company Background."
       
  On December 5, 1993, Software Americas and SAG entered into a Products and
Research & Development Operations Transfer Agreement (the "R&D Agreement")
which required Software Americas to provide certain services relating to
certain SAG employees who utilized Software Americas facilities. In connection
with the Recapitalization, on March 31, 1997, Software Americas entered into
an Administrative Services Agreement (the "ASA") with SAG, terminating the R&D
Agreement and requiring that Software Americas provide services similar to
those required under the R&D Agreement. SAG is required under the ASA to
reimburse Software Americas for its costs incurred in connection with the ASA
and to pay Software Americas $500,000 per year during the years 1997, 1998 and
1999 for the use of certain machinery leased by Software Americas. In 1994,
1995, 1996 and the first nine months of 1997, payments to Software Americas
under the R&D Agreement and the ASA were approximately $7.5 million, $8.8
million, $15.9 million and $8.7 million, respectively.     
   
  From 1988 until the Recapitalization, the Company was a wholly owned
subsidiary of SAG. Accordingly, during that period, there were a variety of
intercompany transactions, including loans and dividends, between the Company
and SAG. In 1994, 1995 and 1996, the Company paid aggregate dividends to SAG
of $0.6 million, $1.7 million and $9.0 million, respectively. Except as
described above, all of these transactions that were material terminated in
connection with the Recapitalization. See "Dividend Policy" and Note 6 of the
Notes to the Consolidated Financial Statements.     
   
  On August 22, 1997, the Company entered into a subscription agreement with
Timothy L. Hill, the Company's Vice President--Marketing, pursuant to which
the Company issued and sold to Mr. Hill 137,500 shares of Common Stock for an
aggregate purchase price of $202,095. Pursuant to the subscription agreement,
the Company has the right to repurchase Mr. Hill's shares at $1.47 per share
if Mr. Hill's employment with the Company is terminated for cause or if Mr.
Hill voluntarily terminates his employment prior to August 17, 1999. The
Company's repurchase right terminates in the event of a change of control of
the Company. In addition, the Company has issued options to purchase an
aggregate of 94,325 shares of Common Stock at an exercise price of $1.47 to
the members of Thayer's Advisory Board.     
   
  The Company and Thayer have entered into a registration rights agreement for
the benefit of all holders as of September 26, 1997 of "restricted securities"
of the Company within the meaning of Rule 144 of the Commission, and certain
transferees of such holders. Pursuant to this agreement, a majority-in-
interest of such holders has the right to require the Company to register
their restricted securities for resale under the Securities Act on up to five
occasions (only one of which may be on Form S-1) and such holders have been
granted certain "piggy-back" registration rights with regard to certain
securities offerings initiated by the Company. The Company has agreed to pay
certain expenses in connection with such registrations.     
   
  Messrs. Gillis, McCreery, Daly and Gorley borrowed $250,000, $250,000,
$182,605 and $75,000, respectively, from Software Americas under individual
promissiory notes, each of which is dated March 24, 1997, and Messrs. McCreery
and Daly borrowed $363,000 and $120,740, respectively, from Software Americas
under individual promissory notes, each of which is dated August 9, 1996. Each
of the promissory notes accrues interest at the rate of 6% per annum and is
due and payable upon termination of its maker's employment with Software
Americas.

                         DESCRIPTION OF CAPITAL STOCK
 
  The authorized capital stock of the Company consists of 75,000,000 shares of
Common Stock, $.01 par value per share, and 25,000,000 shares of preferred
stock, $.01 par value per share (the "Preferred Stock").
 
  The following summary of certain provisions of the Common Stock and
Preferred Stock does not purport to be complete and is subject to, and
qualified in its entirety by, the provisions of applicable law and by the
Company's Certificate of Incorporation, a copy of which is filed as an exhibit
to the Registration Statement of which this Prospectus is a part.
 
COMMON STOCK
   
  As of October 15, 1997, there were 24,337,500 shares of Common Stock
outstanding held of record by 18 stockholders. Based on the number of shares
outstanding as of that date and giving effect to the issuance of the 4,600,000
shares of Common Stock being offered by the Company hereby, there will be
28,937,500 shares of Common Stock outstanding upon the consummation of this
offering.     
   
  Holders of Common Stock are entitled to one vote per share on all matters to
be voted on by stockholders. There are no cumulative voting rights. All
outstanding shares of Common Stock are, and all shares of Common Stock issued
and sold in this offering will be, duly authorized, validly issued, fully paid
and nonassessable. Subject to such preferential rights as may be granted by
the Board of Directors in connection with the issuance of Preferred Stock,
distributions may be paid to the holders of Common Stock when, as and if
declared by the Board of Directors out of funds legally available therefore.
The Company does not intend to pay cash dividends on its Common Stock in the
foreseeable future. See "Dividend Policy." Holders of Common Stock have no
preemptive or other rights to subscribe for additional shares of Common Stock,
redemption rights or conversion rights. Upon liquidation, dissolution or
winding up of the Company, the holders of the Common Stock are entitled to
share ratably in all assets of the Company that are legally available for
distribution after payment of all debts and other liabilities and subject to
any prior rights of holders of Preferred Stock, if any, then outstanding.     
 
PREFERRED STOCK
 
  The Board of Directors has authority to issue 25,000,000 shares of Preferred
Stock in one or more series and to fix the relative rights, preferences,
privileges, qualifications, limitations and restrictions thereof, including
dividend rights, dividend rates, conversion rights, voting rights, terms of
redemption, redemption prices, liquidation preferences and the number of
shares constituting any series or the designation of such series, without
further vote or action by the stockholders. The Board of Directors could,
without the approval of the stockholders, issue Preferred Stock having voting
or conversion rights that could adversely affect the voting power of the
holders of Common Stock, and the issuance of Preferred Stock could be used,
under certain circumstances, to render more difficult or discourage a hostile
takeover of the Company. The Company has no present plans to issue any shares
of Preferred Stock.
 
LIMITATION ON LIABILITY AND INDEMNIFICATION OF DIRECTORS
 
  The Company has adopted provisions in its Certificate of Incorporation
limiting the liability of directors of the Company for monetary damages. The
effect of this provision in the Certificate of Incorporation is to eliminate
the rights of the Company and its stockholders (through stockholders'
derivative suits on behalf of the Company) to recover monetary damages against
a director for breach of the fiduciary duty of care as a director (including
breaches resulting from negligent or grossly negligent behavior) except in
certain limited situations. This provision does not limit or eliminate the
rights of the Company or any stockholder to seek nonmonetary relief such as an
injunction or rescission in the event of a breach of a director's duty of
care. The provisions of the Certificate of Incorporation described above apply
to an officer of the Company only if
 
                                      54
<PAGE>
 
he or she is a director of the Company and is acting in his or her capacity as
director, and do not apply to officers of the Company who are not directors.
These provisions will not alter the liability of directors under federal
securities laws.
 
  The Company's Certificate of Incorporation and Bylaws contain provisions
indemnifying the directors and officers of the Company to the fullest extent
permitted by the Delaware General Corporate Law ("DGCL"). The Company believes
that these provisions will assist the Company in attracting and retaining
qualified individuals to serve as directors and officers.
 
CERTAIN PROVISIONS OF DELAWARE LAW, THE CERTIFICATE OF INCORPORATION AND THE
BYLAWS
   
  The Company is subject to the provisions of Section 203 of the DGCL. Subject
to certain exceptions, Section 203 prohibits a Delaware corporation from
engaging in a "business combination" with an "interested stockholder" for a
period of three years after the date of the transaction in which the person
became an interested stockholder, unless the interested stockholder attained
such status with the approval of the Board of Directors, the business
combination is approved in a prescribed manner or certain other conditions are
satisfied. A "business combination" includes, among other transactions,
mergers, asset sales and other transactions resulting in a financial benefit
to the interested stockholder. Subject to certain exceptions, an "interested
stockholder" is a person who, together with affiliates and associates, owns,
or within three years did own, 15% or more of the corporation's voting stock.
    
  The Company's Certificate of Incorporation and Bylaws contain certain
provisions that could make more difficult the acquisition of the Company by
means of a tender offer, a proxy contest or otherwise. These provisions are
intended to discourage certain types of coercive takeover practices and
inadequate takeover bids and to encourage persons seeking to acquire control
of the Company to negotiate first with the Board of Directors. The Company
believes that the benefits of these provisions outweigh the potential
disadvantages of discouraging such proposals because, among other things,
negotiation of such proposals might result in an improvement of their terms.
   
  Classified Board of Directors. The Certificate of Incorporation provides
that, upon consummation of an underwritten public offering of the Company's
Common Stock, the Board of Directors will be divided into three classes of
directors, each class constituting approximately one-third of the total number
of directors and the classes serving staggered three-year terms. The
classification of directors will have the effect of making it more difficult
for stockholders to change the composition of the Board of Directors. The
Company believes, however, that the longer time required to elect a majority
of a classified Board of Directors will help to ensure continuity and
stability of the Company's management and policies. The classification
provisions could also have the effect of discouraging a third party from
accumulating large blocks of the Company's Common Stock or attempting to
obtain control of the Company, even though such an attempt might be beneficial
to the Company and its stockholders. Accordingly, stockholders could be
deprived of certain opportunities to sell their shares of Common Stock at a
higher market price than might otherwise be the case. See "Management--
Executive Officers and Directors."     
   
  Number of Directors; Removal; Filling Vacancies. The Certificate of
Incorporation provides that the number of directors will be fixed by, or
determined pursuant to, the Bylaws. The Bylaws provide that the Board of
Directors shall consist of six directors and that the Board of Directors may
increase or decrease the number of directors. The Bylaws also provide that,
after consummation of an underwritten public offering of the Company's Common
Stock, the number of directors shall not be increased by 50% or more in any
12-month period without the approval of at least two-thirds of the directors
then in office. The Certificate of Incorporation provides that any vacancies
will be filled only by the affirmative vote of a majority of the remaining
directors then in office, even if less than a quorum. Accordingly, the Board
of Directors could temporarily prevent any stockholder from enlarging the
Board of Directors and filling the new directorships with such stockholder's
own nominees. The Certificate of Incorporation also provides that directors
(or the entire Board) may be removed from office by the stockholders for cause
by the vote of the holders of at least a majority of the Common Stock.     
 
 
                                      55
<PAGE>
 
   
  No Stockholder Action by Written Consent; Special Stockholder Meetings. The
Certificate of Incorporation provides that, after the consummation of an
underwritten public offering of the Company's Common Stock, stockholder action
can be taken only at an annual or special meeting of stockholders and can not
be taken by written consent in lieu of a meeting. The Bylaws provide that
special meetings of the stockholders may be called only by the Chairman of the
Board of Directors, a majority of the Board of Directors or the Chief
Executive Officer of the Company. These provisions may have the effect of
delaying consideration of a stockholder proposal until the next annual
stockholder meeting. These provisions may also discourage another person or
entity from making a tender offer for the Company's Common Stock.     
 
  Advance Notice Provisions for Stockholder Nominations and Stockholder
Proposals. The Bylaws establish an advance notice procedure for stockholders
to make nominations of candidates for election as directors or to bring other
business before an annual meeting of stockholders of the Company (the
"Stockholder Notice Procedure"). The Stockholder Notice Procedure provides
that (i) only persons who are nominated by, or at the direction of, the Board
of Directors, or by a stockholder who has given timely written notice
containing specified information to the Secretary of the Company prior to the
meeting at which directors are to be elected, will be eligible for election as
directors of the Company and (ii) at an annual meeting only such business may
be conducted as has been brought before the meeting by, or at the direction
of, the Board of Directors, or by a stockholder who has given timely written
notice to the Secretary of the Company of such stockholder's intention to
bring such business before the meeting. Except for stockholder proposals
submitted in accordance with the federal proxy rules as to which the
requirements specified therein shall control, notice of stockholder
nominations or business to be conducted at a meeting must be received by the
Company not less than 60 days nor more than 90 days prior to the date of the
annual meeting if the notice is to be submitted at an annual meeting, or not
later than 10 days following the day on which notice of the date of a special
meeting was given if the notice is to be submitted at a special meeting.
 
  The purpose of requiring stockholders to give the Company advance notice of
nominations and other business is to afford the Board of Directors a
meaningful opportunity to consider the qualifications of the proposed nominees
or the advisability of the other proposed business and, to the extent deemed
necessary or desirable by the Board of Directors, to inform stockholders and
make recommendations about such qualifications or business, as well as to
provide a more orderly procedure for conducting meetings of stockholders.
Although the Bylaws do not give the Board of Directors any power to disapprove
stockholder nominations for the election of directors or proposals for action,
they may have the effect of precluding a contest for the election of directors
or the consideration of stockholder proposals if the proper procedures are not
followed and of discouraging or deterring a third party from conducting a
solicitation of proxies to elect its own slate of directors or to approve its
own proposal without regard to whether consideration of such nominees or
proposals might be harmful or beneficial to the Company and its stockholders.
   
  Amendment of Certificate of Incorporation and Bylaws. The Certificate of
Incorporation provides that, after consummation of an underwritten public
offering of the Company's Common Stock, the provisions therein relating to the
staggered Board of Directors, the availability of action by written consent by
stockholders, removal of directors and filling of vacancies on the Board of
Directors may be amended, altered, changed or repealed only by the affirmative
vote of the holders of at least two-thirds of the voting power of all the
shares of capital stock then entitled to vote, voting as a single class. The
Certificate of Incorporation also provides that the Bylaws may be adopted,
amended, altered, changed or repealed by the affirmative vote of the majority
of the members of the Board of Directors. After consummation of an
underwritten public offering of the Company's Common Stock, any action taken
by the stockholders with respect to adopting, amending, altering, changing or
repealing any Bylaw may be taken only by the affirmative vote of the holders
of at least two-thirds of the voting power of all of the shares of capital
stock then entitled to vote generally in the election of directors, voting as
a single class.     
 
TRANSFER AGENT AND REGISTRAR
   
  The Transfer Agent and Registrar for the Company's Common Stock is Bank of
New York.

                        SHARES ELIGIBLE FOR FUTURE SALE
 
  Prior to this offering, there has been no market for the Common Stock of the
Company. Future sales of substantial amounts of Common Stock in the public
market, or the perception that such sales might occur, could adversely affect
the market price of the Common Stock and could impair the ability of the
Company to raise equity capital in the future.
   
  Upon completion of this offering, the Company will have 28,937,500
outstanding shares of Common Stock (assuming no exercise of the Underwriters'
over-allotment option). Of these shares, the 7,700,000 shares of Common Stock
sold in this offering will be freely tradable without restriction or further
registration under the Securities Act, except for any shares purchased by
"affiliates" of the Company, as that term is defined under the Securities Act
and the regulations promulgated thereunder (an "Affiliate"). The remaining
21,237,500 shares of Common Stock (the "Restricted Shares") held by existing
stockholders were sold by the Company in reliance on exemptions from the
registration requirements of the Securities Act and are "restricted
securities" within the meaning of Rule 144.     
   
  Notwithstanding possible earlier eligibility for sale under the provisions
of Rules 144, 144(k) or 701 promulgated under the Securities Act, of the
Restricted Shares, 2,750,000 shares will be eligible for sale beginning 90
days after the date of this Prospectus (all of which will be subject to 180-
day lock-up agreements between certain shareholders and the Representatives of
the Underwriters), and 18,487,500 additional shares will be eligible for sale
beginning March 31, 1998 (all of which will be subject to 180-day lock-up
agreements).     
   
  All of the holders of Restricted Shares have agreed with the Representatives
that, until 180 days from the effective date of the Registration Statement of
which this Prospectus is a part, subject to certain limited exceptions, they
will not, directly or indirectly, sell, offer, contract to sell, pledge, grant
any option to purchase or otherwise dispose of any shares of Common Stock or
any securities convertible into, or exchangeable for, or any rights to
purchase or acquire, shares of Common Stock, owned directly by such holders or
with respect to which they have the power of disposition, without the prior
written consent of BancAmerica Robertson Stephens. BancAmerica Robertson
Stephens may, in its sole discretion and at any time without notice, release
all or any portion of the securities subject to the lockup agreements.     
   
  In general, under Rule 144 as currently in effect, beginning 90 days after
the date of this Prospectus, any holder of Restricted Shares, including an
Affiliate of the Company, as to which at least one year has elapsed since the
later of the date of the acquisition of such Restricted Shares from the
Company or an Affiliate, would be entitled within any three-month period to
sell a number of shares that does not exceed the greater of 1% of the then
outstanding shares of Common Stock (289,375 shares immediately following the
closing of this offering) or the average weekly trading volume of the Common
Stock during the four calendar weeks preceding the date on which notice of the
sale is filed with the Commission. Sales under Rule 144 are also subject to
certain manner of sale provisions, notice requirements and the availability of
current public information about the Company. Affiliates of the Company must
comply with the restrictions and requirements of Rule 144 (except for the one-
year holding period requirement) in order to sell shares of Common Stock which
are not "restricted securities" (such as shares acquired by Affiliates in this
offering).     
 
  Further, under Rule 144(k) a person who holds restricted shares as to which
at least two years have elapsed since the later of their acquisition from the
Company or an Affiliate, and who is not deemed to have been an Affiliate of
the Company at any time during the three months preceding a sale, is entitled
to sell such shares under Rule 144 without regard to volume limitations,
manner of sale provisions, notice requirements or availability of current
public information concerning the Company.
   
  Rule 701 permits resales of shares in reliance upon Rule 144 but without
compliance with certain restrictions, including the holding period
requirement, of Rule 144. Any employee, officer or director of or consultant
to the Company who purchased his or her shares pursuant to a written
compensatory plan or contract may be entitled to rely on the resale provisions
of Rule 701. Rule 701 permits affiliates to sell their Rule 701 shares under
Rule 144 without complying with the holding period requirements of Rule 144.
Rule     
 
                                      57
<PAGE>
 
   
701 further provides that non-affiliates may sell such shares in reliance on
Rule 144 without having to comply with the holding period, public information,
volume limitation or notice provisions of Rule 144. In both cases, a holder of
Rule 701 shares is required to wait until 90 days after the date of this
Prospectus before selling such shares.     
   
  As of October 15, 1997, options to purchase 4,947,525 shares were
outstanding under the Stock Option Plan, and an additional 1,927,475 shares
were reserved for issuance under the Stock Option Plan. The Company intends to
file a registration statement on Form S-8 under the Securities Act covering
the shares issuable and reserved for issuance under the Stock Option Plan.
Such registration statement is expected to be filed and become effective as
soon as practicable after consummation of this offering. After the effective
date of such registration statement, shares of Common Stock issued under the
Stock Option Plan will be immediately eligible for sale in the public market,
subject in certain cases to the lock-up restrictions described above and to
Rule 144 volume limitations applicable to Affiliates.     
   
  All holders of Restricted Shares have been granted certain rights to have
their shares of Common Stock registered for sale under the Securities Act. See
"Certain Relationships and Transactions."

  The Company has been advised by the Representatives that the Underwriters
propose to offer the shares of Common Stock to the public at the initial
public offering price set forth on the cover page of this Prospectus and to
certain dealers at such price less a concession of not more than $    per
share, of which $   per share may be reallowed to other dealers. After the
initial public offering, the public offering price, concession and reallowance
to dealers may be reduced by the Representatives.
   
  The Company and the Selling Stockholders have granted to the Underwriters an
option, exercisable during the 30-day period after the date of this
Prospectus, to purchase an aggregate of up to an additional 1,155,000 shares
of Common Stock at the same price per share as the Company and the Selling
Stockholders receive for the 7,700,000 shares that the Underwriters have
agreed to purchase. To the extent that the Underwriters exercise such option,
each of the Underwriters will have a firm commitment to purchase approximately
the same percentage of such additional shares that the number of shares of
Common Stock to be purchased by it shown in the above table represents as a
percentage of the 7,700,000 shares offered hereby. If purchased, such
additional shares will be sold by the Underwriters on the same terms as those
on which the 7,700,000 shares are being sold. The Company and the Selling
Stockholders subject to such over-allotment option will be obligated, pursuant
to the option, to sell shares to the Underwriters to the extent the option is
exercised. The Underwriters may exercise such option only to cover over-
allotments made in connection with the sale of shares of Common Stock offered
hereby.     
   
  The Underwriting Agreement contains covenants of indemnity among the
Underwriters, the Company and the Selling Stockholders against certain civil
liabilities, including liabilities under the Securities Act and liability
arising from breaches of representations and warranties contained in the
Underwriting Agreement or the inaccuracy of certain information set forth
herein that was provided by the Underwriters.     
   
  All current executive officers, directors and stockholders of the Company
will have agreed with the Representatives that, until 180 days from the
effective date of the Registration Statement of which this Prospectus is a
part, subject to certain limited exceptions, they will not, directly or
indirectly, offer, sell, contract to sell, grant any option to purchase,
pledge, or otherwise dispose of or transfer, any shares of Common Stock, or
any securities convertible into or exchangeable for, or any rights to purchase
or acquire, shares of Common Stock, now owned or hereafter acquired by such
holders or with respect to which they have or hereafter acquire the power of
disposition, without the prior written consent of BancAmerica Robertson
Stephens. BancAmerica

Robertson Stephens may, in its sole discretion and without notice, release all
or any portion of the securities subject to the lock-up agreements. In
addition, the Company has agreed that, until 180 days from the date of this
Prospectus, the Company will not, without the prior written consent of
BancAmerica Robertson Stephens, subject to certain exceptions, sell or
otherwise dispose of any shares of Common Stock, any options or warrants to
purchase any shares of Common Stock or any securities convertible into,
exercisable for or exchangeable for shares of Common Stock other than the
Company's sale of shares in this offering, the issuance of Common Stock upon
the exercise of outstanding options, or the Company's grant of options and
issuance of stock under the Stock Option Plan. See "Shares Eligible for Future
Sale."     
 
  The Representatives have advised the Company and the Selling Stockholders
that the Underwriters do not intend to confirm sales to accounts over which
they exercise discretionary authority.
 
  Certain persons participating in this offering may overallot or effect
transactions which stabilize, maintain or otherwise affect the market price of
the Common Stock at levels above those which might otherwise prevail in the
open market, including by entering stabilizing bids, effecting syndicate
covering transactions or imposing penalty bids. A stabilizing bid means the
placing of any bid or effecting of any purchase for the purpose of pegging,
fixing or maintaining the price of the Common Stock. A syndicate covering
transaction means the placing of any bid on behalf of the underwriting
syndicate or the effecting of any purchase to reduce a short position created
in connection with this offering. A penalty bid means an arrangement that
permits the Underwriters to reclaim a selling concession from a syndicate
member in connection with this offering when shares of Common Stock sold by
the syndicate member are purchased in syndicate covering transactions. Such
transactions may be effected, where permitted, on the NYSE or otherwise. Such
stabilizing, if commenced, may be discontinued at any time.
 
  The Underwriters have reserved for sale, at the initial public offering
price, up to 5% of the shares of Common Stock offered hereby for employees of
the Company and certain individuals who have expressed an interest in
purchasing shares of Common Stock in this offering. The number of shares
available for sale to the general public will be reduced to the extent such
persons purchase such reserved shares. Any reserved shares not so purchased
will be offered by the Underwriters to the general public on the same basis as
other shares offered hereby.
 
  Prior to this offering, there has been no public market for the Common Stock
of the Company. Consequently, the initial public offering price for the Common
Stock will be determined through negotiations among the Company and the
Representatives. The material factors to be considered in such negotiations
will be prevailing market and economic conditions, certain financial
information of the Company for recent periods, the market valuations of other
companies engaged in activities similar to those of the Company, estimates of
the business potential and prospects of the Company, the present state of the
Company's business operations, the Company's management and other factors
deemed relevant. The estimated initial public offering price range set forth
on the cover of this preliminary prospectus is subject to change as a result
of market conditions and other factors. There can be no assurance that an
active or orderly trading market will develop for the Common Stock or that the
Common Stock will trade in the public market subsequent to this offering at or
above the initial trading price. See "Risk Factors--No Prior Market for Common
Stock and Possible Volatility of Common Stock Price".

                         INDEPENDENT AUDITORS' REPORT
 
Board of Directors
Software AG Systems, Inc.:
 
  We have audited the accompanying consolidated balance sheets of Software AG
Systems, Inc. and subsidiaries as of December 31, 1995 and 1996, and the
related consolidated statements of operations, stockholder's equity, and cash
flows for each of the years in the three-year period ended December 31, 1996.
These consolidated financial statements are the responsibility of the
Company's management. Our responsibility is to express an opinion on these
consolidated 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 financial position of Software
AG Systems, Inc. and subsidiaries as of December 31, 1995 and 1996, and the
results of their operations and their cash flows for each of the years in the
three-year period ended December 31, 1996, in conformity with generally
accepted accounting principles.

                       DECEMBER 31, 1994, 1995 AND 1996
 
(1) DESCRIPTION OF OPERATIONS AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
 Reporting Entity and Principles of Consolidation
 
  Software AG Systems, Inc. and subsidiaries (the "Company") is a wholly owned
subsidiary of Software AG, a German corporation ("SAG"). Subsequent to year-
end 1996, the Company was recapitalized. See note 14.
 
  The consolidated financial statements include the accounts of Software AG
Systems, Inc. and its wholly owned subsidiaries, including Software AG
Americas, Inc. (formerly Software AG of North America, Inc.).
 
  All inter-company balances and transactions between the Company and its
wholly owned subsidiaries have been eliminated.
 
 Description of Operations
   
  The Company provides software products and professional services utilized by
organizations to build and enhance enterprise-level applications. The
Company's products are used for mission-critical applications that require
reliability, scaleability and security, such as customer billing systems,
financial accounting systems, and inventory management. The Company's business
is focused on database management and applications development products. The
Company markets and sells its software products and services, as well as
third-party products, through direct and indirect channels in North America,
South America, Japan and Israel.     
 
 Revenue Recognition
 
  The Company recognizes revenue in accordance with the provisions of the
American Institute of Certified Public Accountants Statement of Position No.
91-1, Software Revenue Recognition.
 
  Product license revenues are recognized when there is an executed license
agreement, the software and authorization code have been delivered,
collectibility from the customer is probable, and there are no significant
remaining obligations to the customer.
 
  Maintenance revenues, which include unspecified when-and-if deliverable
software upgrades, user documentation, and technical support for software
products, are deferred and recognized on a straight-line basis over the term
of the maintenance agreement, generally one year.
 
  Customer training revenues and revenues from time and material type
professional consulting and custom application contracts are recognized as the
services are provided and the work is performed. Revenues from long-term fixed
price professional consulting and custom application contracts are accounted
for under the percentage of completion method. When estimates of costs, on
long-term fixed price contracts, indicate a loss, such a loss is provided for
currently.
 
  Sales of enterprise license agreements, which generally bundle a combination
of products, technical services, and professional consulting services, are
accounted for according to their component parts using the criteria described
above.
 
 Property, Equipment and Leasehold Improvements
 
  Property, equipment and leasehold improvements are recorded at cost.
Depreciation of property and equipment is provided on a straight-line basis
over the estimated useful asset lives, generally 31.5 years for property and
three to five years for equipment. Leasehold improvements are amortized on a
straight-line basis over the lesser of the respective lease term or estimated
useful asset lives.

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(CONTINUED)
 
                       DECEMBER 31, 1994, 1995 AND 1996
   
 Income Taxes     
 
  The Company uses the asset and liability method to account for income taxes.
Under the asset and liability method, deferred income taxes are recognized for
the future tax consequences attributable to future years for differences
between the financial statement carrying amounts and the tax bases of existing
assets and liabilities. Deferred tax assets and liabilities are measured using
enacted tax rates expected to apply to taxable income in the years in which
those temporary differences are expected to be recovered or settled. The
effect on deferred taxes of a change in tax rates is recognized in income in
the period that includes the enactment date.
 
 Use of Estimates
 
  The preparation of consolidated 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
consolidated financial statements and the reported amounts of revenues and
expenses during the reporting period. Actual results could differ from those
estimates.
 
 Cash Equivalents
 
  The Company considers all highly liquid instruments with a maturity of three
months or less at time of purchase to be cash equivalents. Cash equivalents
consist of commercial paper and overnight repurchase agreements.
 
 Net Income per Share
 
  Net income per share is computed using the weighted average number of common
and common equivalent shares outstanding during the period. Pursuant to the
Securities and Exchange Commission Staff Accounting Bulletins and staff
policy, such computations include all common and common equivalent shares
issued within the 12 months preceding the Company's initial public offering as
if they were outstanding for all periods presented. See note 14.
 
(2) CONCENTRATIONS OF CREDIT RISK AND FAIR VALUES OF FINANCIAL INSTRUMENTS
 
 Concentrations of Credit Risk
 
  Financial instruments that potentially subject the Company to credit risk
include accounts receivable and cash. Management believes that credit risk
related to the Company's accounts receivable is limited due to a large number
of customers in differing industries and geographic areas. The Company does
not require collateral for accounts receivable. Historically, the Company has
not experienced significant losses on accounts receivable except in isolated
situations. The Company maintains depository relationships with several banks.
At times, the Company's cash deposits may exceed federally insured limits.
Periodically, the Company invests excess cash in low risk, highly liquid
repurchase agreements and other instruments through high credit quality
financial institutions. The Company has not experienced any losses in its
depository accounts or short-term investments and management believes that the
Company is not exposed to any significant credit risks.
 
 Fair Value of Financial Instruments
 
  The carrying amounts of cash, accounts receivable, notes receivable from
SAG, accounts payable, payable to SAG, and amounts included in other current
assets and current liabilities that meet the definition of a financial
instrument, approximate fair value because of the short-term nature of these
amounts.

  In 1995 and 1996, the Company sold installment accounts receivable relating
to certain enterprise license agreements and other long-term contracts to
unrelated financing companies, receiving net proceeds of $28,852,000 and
$28,448,000, respectively. The installment accounts receivable sold include
those relating to product and license fees, technical services, and
professional consulting services. Under the terms of the agreements with the
financing companies, the Company continues to service the receivables sold,
including invoicing and collection, and makes payments to the financing
companies under pre-determined amortization schedules based on the scheduled
invoicing dates of the receivables sold. The amortization schedules provide
rates of return to the financing companies ranging from 8.5% to 8.9%.
 
  The agreements allow for substitution of contracts for early terminations
and require the Company to repurchase contracts that cease to meet eligibility
requirements, such as those contracts that become 90 days past due. At
December 31, 1995 and 1996, the Company remained contingently liable under the
recourse provisions for $26,468,000 and $44,801,000, respectively. The
Company's allowance for doubtful accounts is maintained at a level that
management believes is sufficient to cover potential losses under the recourse
provisions on receivables sold.
 
  Under the terms of the agreements, the Company is required to maintain
specified amounts of net worth and cash availability, and a debt to equity
ratio that does not exceed a specified amount. If the Company fails to
maintain these specified amounts, the financing companies may assume the
servicing rights on receivables sold.
 
 Unbilled Services
 
  Unbilled services relate primarily to long-term professional consulting
services and custom application contracts accounted for using the percentage

  Depreciation and amortization for 1994, 1995, and 1996, was $3,829,000,
$3,733,000, and $3,473,000, respectively.
 
(5) SALE OF CUSTOMER SUPPORT FACILITY
 
  In 1996, the Company recorded a sale-leaseback transaction for its customer
support facility. In connection with the sale, the Company realized a gain of
$2,830,000, which is being recognized on a straight-line basis over the term
of the related operating lease.
 
(6) TRANSACTIONS WITH RELATED PARTY
 
 Royalties
   
  In 1994, the Company licensed and serviced SAG products under a pre-existing
license agreement pursuant to which the Company was required to make payments
to SAG based on a specified percentage of the net sales amount for licenses
of, and technical services on, SAG's products. Effective January 1, 1995, the
Company and SAG entered into a new license agreement whereby the Company was
required to pay royalties of 24% of such net sales amounts. For 1994, 1995 and
1996, royalty expense related to SAG's products was $29,026,000, $23,887,000
and $26,058,000, respectively.     
 
  Under the license agreement, SAG pays royalties to the Company on sales of
the Company's products under the same terms. For 1995 and 1996, royalty
revenues related to the Company's products were $295,000 and $294,000,
respectively.
   
  As more fully described in note 14, prior to the Recapitalization, the
Company and SAG entered into a Cooperation Agreement on March 31, 1997.     
 
 Cost Reimbursements
   
  As an accommodation to SAG, the Company houses certain of SAG's product
development and quality assurance personnel. SAG reimburses the Company for
the costs incurred related to such product development and quality assurance
activities. All intellectual property resulting from this work is the sole
property of SAG. The reimbursements from SAG are netted against costs incurred
and included in software product development costs in the statement of
operations. Reimbursements for 1994, 1995, and 1996, were $7,518,000,
$8,767,000, and $15,931,000, respectively.

                       DECEMBER 31, 1994, 1995 AND 1996
 
 
 Notes Receivable/Payable
 
  In 1995, the Company loaned $20,000,000 to SAG, which originally was
scheduled to be repaid in 2000. In 1996, the Company loaned an additional
$10,000,000 to SAG, which originally was scheduled to be repaid in 2001.
Interest at 6.5% and 7%, respectively, is payable quarterly on the 1995 and
1996 loans. Interest earned for 1995 and 1996 was $280,000 and $1,590,000,
respectively.
 
  The payable to SAG of $17,132,000 and $33,317,000 at December 31, 1995 and
1996, respectively, includes royalties due under the license agreement on
sales of both product licenses and technical services, as well as net amounts
due on other transactions between the Company and SAG. These amounts are non-
interest bearing.
 
  In March, 1997, the Company and SAG agreed to offset the entire balance of
the notes receivable from SAG as of December 31, 1996 against the payable to
SAG.
 
  In 1995, SAG loaned $2,500,000 to the Company, which was repaid during the
year. Interest expense on this note was $119,000, computed at 8%.
 
 Dividends
 
  In 1994, 1995, and 1996, the Company paid dividends of $600,000, $1,700,000
and $9,000,000, respectively, to SAG, which at the time owned 100% of the
outstanding common stock of the Company.

</TABLE>
 
  In assessing the realization of deferred tax assets, management considers
whether it is more likely than not that some portion or all of the deferred
tax assets will not be realized. The ultimate realization of deferred tax
assets is dependent upon the generation of future taxable income during the
periods in which those temporary differences become deductible. Based upon the
level of historical taxable income and projections for future taxable income
over the periods for which the deferred tax assets are deductible, management
believes that it is more likely than not that the Company will realize the
benefits of these deductible differences. The amount of the deferred tax asset
considered realizable, however, could be reduced in the near term if estimates
of future taxable income are reduced.
 
(8) RETIREMENT PLANS
   
  The Company has a retirement plan covering substantially all of its
employees. This plan meets the requirements of Section 401(k) of the Internal
Revenue Code. The Company matches employee contributions and may make
additional contributions based on the Company's profitability. For 1994, 1995,
and 1996, the Company's matching (and total) contributions were $1,967,000,
$1,789,000, and $1,854,000, respectively.

(8) RETIREMENT PLANS--(CONTINUED)
 
  The Company also has entered into deferred compensation agreements with
certain key executives. Under these agreements, the executives are credited
with annual pre-determined amounts and amounts based on bonuses received, and
earn interest on the deferred amounts. Total deferrals, which are included in
accrued payroll and employee benefits, were $3,038,000 and $1,504,000, at
December 31, 1995 and 1996, respectively, net of loans of $0 and $558,000,
respectively. The expense for these agreements was $653,000 and $1,218,000,
for 1995 and 1996, respectively. To assist in the funding of these agreements
the Company has purchased corporate-owned life insurance on certain of these
executives. The cash surrender value of these policies, which is included in
other assets, was $1,067,000 and $668,000, at December 31, 1995 and 1996,
respectively.
 
(9) OPERATING LEASE COMMITMENTS
 
  The Company leases office space and equipment under operating lease

  Facility rent expense for 1994, 1995, and 1996, was $5,942,000, $6,105,000,
and $7,002,000, respectively. Rent expense includes the current year effect of
determinable scheduled rent increases and initial rent abatement periods
contained in certain of the Company's facility lease agreements.
 
  Equipment lease expense for 1994, 1995, and 1996, was $706,000, $l,532,000,
and $1,678,000, respectively.
 
  The Company's operating lease agreement for its customer support facility
requires the Company to maintain minimum amounts of net worth and retained
earnings. If the minimum amounts are not maintained, the Company will be
required to post a $500,000 irrevocable letter of credit for each $2,000,000
shortfall, to be applied by the lessor in the event of default under the
lease.
 
(10) CONTINGENCIES
 
  The Company is involved in various claims and legal proceedings of a nature
considered normal to its business, primarily relating to product and contract
performance issues, and employee termination matters. While it is not feasible
to predict or determine the final outcome of these proceedings, management
does not believe that they will have a material adverse effect on the
Company's financial position or results of operations.

Share," which is effective for all interim and annual periods ending after
December 15, 1997. This statement replaces "primary" and "fully diluted"
earnings per share ("EPS") with "basic" and "diluted" EPS on the face of the
statement of operation.     
 
  In June 1997, the FASB issued SFAS No. 130, "Reporting Comprehensive
Income," which is effective for the year ending December 31, 1998. This
statement established standards for the reporting and display of comprehensive
income and its components in the financial statements. Earlier application of
this standard is permitted. However, upon its adoption the Company will be
required to reclassify previously reported annual and interim financial
statements.
 
  The Company does not expect that the adoption of these new accounting
standards will have a material effect on the Company's financial position or
results of operation.

  On March 31, 1997, the Company consummated a Recapitalization Agreement
under which the Company repurchased from its parent 24,750,000 shares of
common stock and sold 21,450,000 shares of common stock to an unrelated entity
and certain of the Company's senior managers.

                       DECEMBER 31, 1994, 1995 AND 1996
   
(14) SUBSEQUENT EVENTS--(CONTINUED)     
   
  Prior to the consummation of the Recapitalization Agreement, the Company
entered into a perpetual (unless otherwise terminated by the written agreement
of the parties) Cooperation Agreement with SAG that terminated and superseded
the license agreement dated January 1, 1995. As consideration for the
Cooperation Agreement, the Company paid SAG approximately $22,600,000. Under the
Cooperation Agreement, each of the Company and SAG are required to pay the other
royalties of 24% of net revenues from sales of licenses of, and technical
services on, each other's products for the initial 20 years of the perpetual
term of the agreement. For calendar years 1997 through 2000, the Company will be
required to pay SAG minimum annual royalties of $21,000,000, provided that SAG's
worldwide product and technical services revenues for each of those years are at
least equal to SAG's 1996 worldwide revenues. In the event of a decrease in
SAG's worldwide revenues, the minimum annual royalty requirement will be reduced
proportionately.     
   
  In connection with the Recapitalization Agreement, which was consummated on
March 31, 1997, the Company authorized the granting of stock options to
acquire an aggregate of 3,300,000 shares of common stock at an exercise price
of $1.47, of which options to acquire an aggregate of 3,059,650 shares have
been granted. This exercise price represents the amount per share that Thayer
and management paid to acquire approximately an 89% interest in the Company on
March 31, 1997 pursuant to the Recapitalization Agreement. The Company adopted
the Software AG Systems, Inc. 1997 Stock Option Plan (the "Plan") on April 29,
1997. On August 8, 1997, 749,650 and 106,975 options were granted with
exercise prices of $9.60 and $1.47 per share, respectively, under the Plan. On
September 23, 1997, 1,031,250 options were granted with an exercise price of
$12.00 per share, under the Plan.     
          
  On September 30, 1997, the Company acquired 100% of the issued and
outstanding shares of the common stock of R.D. Nickel and Associates, Inc.
("Nickel"). The transaction was accounted for using the purchase method of
accounting for a business combination. The aggregate purchase price of
Cdn$14,000,000 (US$10,130,000) was funded through a cash payment of
Cdn$7,000,000 (US$5,065,000) and a note payable of Cdn$7,000,000
(US$5,065,000).     
   
  Nickel is a software company that has a family of application development
products and that has been the exclusive distributor of SAG's products in
Canada since 1973.     
   
  In connection with the transaction, the Company recorded a $6,051,000 non-
recurring charge against earnings for in-process research and development
costs. The remaining excess purchase price of $4,864,000 represents goodwill,
and has been recorded as other intangible assets. The related amortization
period for the goodwill is ten years.     
   
  In September, 1997, the Company's Board of Directors authorized management
of the Company to file a Registration Statement with the Securities and
Exchange Commission permitting the Company to sell shares of its common stock
to the public. The Company's Board of Directors also approved a 275-for-1
stock split to be effected prior to the closing of the initial public offering
of the Company's common stock. Common share and per share data in these
consolidated financial statements have been retroactively adjusted to reflect
the stock split. Additionally, the Company's Certificate of Incorporation was
amended and restated to authorize an additional 20,000,000 shares of $.01 par
value common stock and an additional 11,250,000 shares of $.01 par value
preferred stock, for a total of 75,000,000 authorized shares of common stock
and 25,000,000 authorized shares of $.01 par value preferred stock. The
Company had previously authorized 13,750,000 shares of $.01 par value
preferred stock on March 14, 1997.

        NOTES TO UNAUDITED CONDENSED CONSOLIDATED FINANCIAL STATEMENTS
 
(1) BASIS OF PRESENTATION
   
  In the opinion of management, the accompanying unaudited condensed
consolidated financial statements reflect all adjustments, consisting of only
normal recurring accruals, necessary for a fair presentation of the financial
position of Software AG Systems, Inc. and subsidiaries (the "Company") as of
September 30, 1997, and the results of its operations for the nine months
ended September 30, 1996, and the three-month period ended March 31, 1997 and
the six month period ended September 30, 1997. These condensed consolidated
financial statements are unaudited and do not include all related footnote
disclosures. The September 30, 1997 condensed consolidated balance sheet
reflects the Recapitalization of the Company (see note 2), and is not
comparative to the financial positions of prior periods. The interim unaudited
condensed financial statements should be read in conjunction with the audited
financial statements.     
   
  The Company's results of operations for the nine months ended September 30,
1996 and the three month period ended March 31, 1997, respectively, are based
on operations which occurred prior to the acquisition of the Company by Thayer
Equity Investors III, L.P. ("Thayer") and certain members of the Company's
management and are not comparative with the results of operations for the six
month period ended September 30, 1997. The results of operations for the three
month period ended March 31, 1997 and the six month period ended September 30,
1997 are not necessarily indicative of the results of operations to be
expected in the future.     
 
(2) RECAPITALIZATION OF THE COMPANY
   
  On March 31, 1997, the Company consummated a Recapitalization Agreement
under which the Company repurchased from its former parent, Software AG, a
German corporation ("SAG"), 24,750,000 shares of common stock and sold
21,450,000 shares of common stock to Thayer and certain of the Company's
managers. As a result of this change in control, the acquisition by Thayer and
such managers was accounted for as a purchase business combination, and as
such the fair value of the Company's assets and liabilities was recorded as of
April 1, 1997.     
   
  Prior to the consummation of the Recapitalization Agreement, the Company
entered into a perpetual (unless otherwise terminated by the written agreement
of the parties) Cooperation Agreement with SAG that terminated and superseded
the license agreement dated January 1, 1995. As consideration for the
Cooperation Agreement, the Company paid SAG approximately $22,600,000. Under
the Cooperation Agreement, each of the Company and SAG are required to pay the
other royalties of 24% of net revenues from sales of licenses of, and
technical services on, each other's products for the initial 20 years of the
perpetual term of the agreement. For calendar years 1997 through 2000, the
Company will be required to pay SAG minimum annual royalties of $21,000,000,
provided that SAG's worldwide product and technical services revenues for each
of those years are at least equal to SAG's 1996 worldwide revenues. In the
event of a decrease in SAG's worldwide revenues, the minimum annual royalty
requirement will be reduced proportionately.     
   
  Pursuant to the Recapitalization Agreement, Thayer and certain of the
Company's managers acquired approximately an 89% interest in the Company for
approximately $31.5 million. The determination of fair value allocated to the
identifiable assets and liabilities of the Company has been estimated by
management based on the nature of the assets and liabilities acquired, and
general economic factors. Based on this preliminary allocation, the fair value
of the Company's Cooperation Agreement has been estimated at approximately
$23,500,000, based on an independent appraisal. The fair value of the
Company's remaining assets and liabilities has been presumed to be equal to
the book value as of the date of the acquisition. Based on preliminary
allocation of the purchase price to the net assets and liabilities, an excess
of purchase price over net assets acquired (goodwill) of approximately
$6,401,000 was recorded. Such goodwill is being amortized on a straight-line
basis over 10 years. In the opinion of management of the Company, the final
allocation of the purchase price will not be materially different from the
preliminary purchase price allocation.

  NOTES TO UNAUDITED CONDENSED CONSOLIDATED FINANCIAL STATEMENTS--(CONTINUED)
 
 
(3) STOCK OPTION PLAN
          
  In connection with the Recapitalization Agreement, which was consummated on
March 31, 1997, the Company authorized the granting of stock options to
acquire an aggregate of 3,300,000 shares of common stock at an exercise price
of $1.47, of which options to acquire an aggregate of 3,059,650 shares have
been granted. This exercise price represents the amount per share that Thayer
and management paid to acquire approximately an 89% interest in the Company on
March 31, 1997 pursuant to the Recapitalization Agreement. The Company adopted
the Software AG Systems, Inc. 1997 Stock Option Plan (the "Plan") on April 29,
1997. On August 8, 1997, 749,650 and 106,975 options were granted with
exercise prices of $9.60 and $1.47 per share, respectively, under the Plan. On
September 23, 1997, 1,031,250 options were granted with an exercise price of
$12.00 per share, under the Plan.     
   
(4) ACQUISITION     
   
  On September 30, 1997, the Company acquired 100% of the issued and
outstanding shares of the common stock of R.D. Nickel and Associates, Inc.
("Nickel"). The transaction was accounted for using the purchase method of
accounting for a business combination. The aggregate purchase price of
Cdn$14,000,000 (US$10,130,000) was funded through a cash payment of
Cdn$7,000,000 (US$5,065,000) and a note payable of Cdn$7,000,000
(US$5,065,000).     
   
  Nickel is a software company that has a family of application development
products and that has been the exclusive distributor of SAG's products in
Canada since 1973.     
   
  In connection with the transaction, the Company recorded a $6,051,000 non-
recurring charge against earnings for in-process research and development
costs. The remaining excess purchase price of $4,864,000 represents goodwill,
and has been recorded as other intangible assets. The related amortization
period for the goodwill is ten years.     
   
  At September 30, 1997, the net assets acquired have been reported in the
Company's unaudited condensed consolidated financial statements.     
   
  The Nickel acquisition was not determined to be significant to the
operations or balance sheet of the Company; accordingly, the pro forma
financial information has not been presented.     
   
(5) SUBSEQUENT EVENTS     
          
  In September, 1997, the Company's Board of Directors authorized management
of the Company to file a Registration Statement with the Securities and
Exchange Commission permitting the Company to sell shares of its common stock
to the public. The Company's Board of Directors also approved a 275-for-1
stock split to be effected prior to the closing of the initial public offering
of the Company's Common Stock. Common share and per share data in these
condensed consolidated financial statements have been retroactively adjusted
to reflect the stock split. Additionally, the Company's Certificate of
Incorporation was amended and restated to authorize an additional 20,000,000
shares of $.01 par value Common Stock and an additional 11,250,000 shares of
$.01 par value preferred stock, for a total of 75,000,000 authorized shares of
common stock and 25,000,000 authorized shares of $.01 par value preferred
stock. The Company had previously authorized 13,750,000 shares of $.01 par
value preferred stock on March 14, 1997.

       Total........................................................ $1,100,000
                                                                     ==========
</TABLE>    
  --------
   
  The Company intends to pay all expenses of registration, issuance and
distribution, excluding underwriters' discounts and commissions, with respect
to the shares being sold by the Selling Stockholders. In addition, the Company
expects to pay approximately $100,000 to obtain further director and officer
liability insurance coverage in connection with this offering.     
 
ITEM 14. INDEMNIFICATION OF DIRECTORS AND OFFICERS.
   
  Section 145 of the Delaware General Corporation Law sets forth conditions
and limitations governing the indemnification of officers and directors of the
Company and certain other persons. The Company has adopted provisions in its
Second Amended and Restated Certificate of Incorporation and Second Amended
and Restated Bylaws which provide for indemnification of its officers and
directors to the maximum extent permitted under the Delaware General
Corporation Law.     
   
  As authorized by the Delaware General Corporation Law, the Company's Second
Amended and Restated Certificate of Incorporation limits the liability of
directors of the Company for monetary damages. The effect of this provision is
to eliminate the rights of the Company and its stockholders (through
stockholders' derivative suits on behalf of the Company) to recover monetary
damages against a director for breach of the fiduciary duty of care as a
director (including breaches resulting from negligent or grossly negligent
behavior) except in certain limited situations. This provision does not limit
or eliminate the rights of the Company or any stockholder to seek non-monetary
relief such as an injunction or rescission in the event of breach of a
director's duty of care. These provisions will not alter the liability of
directors under federal securities laws.     
 
  The Company has purchased an insurance policy which purports to insure the
officers and directors of the Company against certain liabilities incurred by
them in the discharge of their functions as such officers and directors except
for liabilities resulting from their own malfeasance.
   
  Under the terms of the Underwriting Agreement, the Underwriters have agreed
to indemnify, under certain conditions, the Company, its directors, certain of
its officers and persons who control the Company within the meaning of the
Securities Act against certain civil liabilities and liabilities arising from
breaches of representations and warranties contained in the Underwriting
Agreement or the inaccuracy of certain information set forth herein that was
provided by the Underwriters.     
 
ITEM 15. RECENT SALES OF UNREGISTERED SECURITIES.
   
  Prior to February 25, 1997, the Company was an indirect wholly owned
subsidiary of Software AG ("SAG"), and on February 25, 1997, the Company

and SAG became the owner of the one outstanding share of the Company's common
stock, par value $1.00 per share.     
   
  On March 31, 1997, the senior management of the Company and Thayer Equity
Investors III, L.P. ("Thayer") acquired approximately 89% of the then
outstanding Common Stock of the Company (the "Recapitalization") pursuant to
an agreement among the Company, SAG, Thayer and the following officers of the
Company: Daniel F. Gillis, Harry K. McCreery, Gary Hayes, James H. Daly, Derek
M. Brigden and Thomas E. Gorley (collectively, such individuals are referred
to as the "Managers"). In connection therewith, (i) 24,750,000 shares of
Common Stock were repurchased by the Company from SAG for an aggregate
purchase price of 57,000,000 Deutsche Marks ($33.9 million), (ii) 20,678,350
shares of Common Stock were issued and sold to Thayer for an aggregate
purchase price of $30,392,662.86 and (iii) an aggregate of 771,650 shares of
Common Stock were issued and sold to the Managers for an aggregate purchase
price of $1,134,157.14. In addition, on August 22, 1997 the Company entered
into a subscription agreement with Timothy L. Hill, the Company's Vice
President--Marketing, pursuant to which the Company issued and sold to Mr.
Hill 137,500 shares of Common Stock for an aggregate purchase price of
$202,095. The Company has also granted options to purchase an aggregate of
4,947,525 shares of Common Stock at a weighted average exercise price equal to
$4.90 per share. All such options and shares of Common Stock were issued in
private placements exempt from registration under Section 4(2) of the
Securities Act of 1933, as amended (the "Securities Act"), or Rule 701
thereunder. All such shares reflect a 275-for-1 stock split with respect to
the Common Stock to be effected as a dividend prior to the effective date of
the Registration Statement. No underwriters were involved in the sales or
issuances of the securities described above.

  An index to exhibits appears on page E-1.
 
ITEM 17. UNDERTAKINGS.
 
  The undersigned registrant hereby undertakes to provide to the Underwriters
at the closing specified in the Underwriting Agreement certificates in such
denominations and registered in such names as required by the Underwriters to
permit prompt delivery to each purchaser.
   
  Insofar as indemnification for liabilities arising under the Securities Act
may be permitted to directors, officers and controlling persons of the
registrant pursuant to the foregoing provisions, or otherwise, the registrant
has been advised that in the opinion of the Securities and Exchange Commission
such indemnification is against public policy as expressed in the Securities
Act and is, therefore, unenforceable. In the event that a claim for
indemnification against such liabilities (other than the payment by the
registrant of expenses incurred or paid by a director, officer or controlling
person of the registrant in the successful defense of any action, suit or
proceeding) is asserted by such director, officer or controlling person in
connection with the securities being registered, the registrant will, unless
in the opinion of its counsel the matter has been settled by controlling
precedent, submit to a court of appropriate jurisdiction the question of
whether such indemnification by it is against public policy as expressed in
the Securities Act and will be governed by the final adjudication of such
issue.     
 
  The undersigned registrant hereby undertakes that:
    (1) For purposes of determining any liability under the Securities Act,
  the information omitted from the form of prospectus filed as part of this
  Registration Statement in reliance upon Rule 430A and contained in a form
  of prospectus filed by the registrant pursuant to Rule 424(b)(1) or (4) or
  479(h) under the Securities Act shall be deemed to be part of this
  registration statement as of the time it was declared effective.
    (2) For the purpose of determining any liability under the Securities
  Act, each post-effective amendment that contains a form of prospectus shall
  be deemed to be a new registration statement relating to the securities
  offered therein, and the offering of such securities at that time shall be
  deemed to be the initial bona fide offering thereof.

with all statutes and regulations applicable to the conduct of its business. The
Company and each Subsidiary has filed all reports required by statute,
regulation or other requirement to be filed with any Governmental Entity, except
where the failure to so file would not have a Material Adverse Effect on the
Company, and such reports were prepared in all material respects in accordance
with the applicable statutes, regulations and instructions in existence as of
the date of filing of such reports. Neither the Company nor any Subsidiary has
received notification from any Governmental Entity (i) asserting a violation of
any, statute, regulation or other requirement or (ii) restricting or in any way
limiting its operations. Neither the Company nor any Subsidiary is subject to
any regulatory or supervisory order, agreement, directive, memorandum of
understanding, commitment or similar requirements and none of them has received
any communication requesting that it enter into any of the foregoing.

3.7.  Financial Statements; Books and Records

      (a)  The Financial Statements fairly present the financial position of the
Company as of the dates indicated and the results of operations, changes in
stockholders' equity and cash flows of the Company for the periods presented,
all in conformity with U.S. generally accepted accounting principles applied on
a consistent basis except as disclosed therein. The books and records of the

<PAGE>
 
                                     - 11 -

included in the Financial Statements dated as of December 31, 1996 (the "1996
Financial Statements") are valid and enforceable and, to the knowledge of
Seller, the Company and the Subsidiaries (collectively, the "Seller's
Knowledge"), collectible net of reserves. Such reserves have been established in
accordance with U.S. generally accepted accounting principles.

        (b)  Seller's Previously Disclosed consolidated balance sheet as of
December 31, 1996 and its related, Previously Disclosed consolidated statement
of income (including related notes, if any) for the year ended December 31,
1996, fairly present Seller's financial position as of the date indicated and
the results of operations of Seller for the period presented, all in conformity
with generally accepted accounting principles applied on a consistent basis
except as disclosed therein.

3.8.    Material Adverse Change

        The Company has not, on a consolidated basis, suffered any material
adverse change in its financial condition, results of operations, business or
prospects since December 31, 1996.

3.9.    Absence of Undisclosed Liabilities

        Except as disclosed in the 1996 Financial Statements, neither the
Company nor any Subsidiary has any Liability that is material to the Company on
a consolidated basis, or that, when combined with all similar Liabilities, would
be material to the Company on a consolidated basis; to the Seller's Knowledge,
no set of circumstances exist that are reasonably likely to give rise to any
such Liability.

3.10.   Properties

        The Company or a Subsidiary has good title, free and clear of all
Encumbrances, to all of the Properties which, individually or in the aggregate,
are material to the business of the Company and its Subsidiaries taken as a
whole, and which are reflected on the 1996 Financial Statements or acquired
after December 31, 1996, except (i) liens for taxes not yet due and payable for
which adequate reserves have been established on the books of the Company and

business of the Company and
<PAGE>
 
                                     - 12 -

its Subsidiaries taken as a whole (x) have been Previously Disclosed and (y) are
valid, in full force and effect and enforceable in accordance with their
respective terms.

3.11.  Permits

       Seller has Previously Disclosed a list and description of all material
Permits which are issued to, held or used by the Company or any Subsidiary, or
for which the Company or any Subsidiary has applied. There are no other required
Permits which are material to (i) the operation of the Company's or any
Subsidiary's business as now conducted or (ii) the ownership or use of any of
the Properties. All Permits Previously Disclosed by Seller are in good standing
and are valid and effective in accordance with their respective terms; such
Permits will continue in effect after the Closing. The Company and its
Subsidiaries are in material compliance with all Permits Previously Disclosed by
Seller, and no governmental proceedings or investigations are pending or, to the
Seller's Knowledge, threatened against Seller, the Company or any Subsidiary
relating to noncompliance with such Permits.


3.12.  Employment Benefit Plans

       Seller has Previously Disclosed true and complete copies of all qualified
pension or profit-sharing plans, any deferred compensation, consulting, bonus or
group insurance contract or any other incentive, welfare or employee benefit
plan or agreement maintained for the benefit of employees or former employees of
the Company or any Subsidiary (collectively, the "Plans"). No liability under
Title IV of the Employment Retirement Income Security Act of 1974, as amended
("ERISA") has been incurred by the Company or any of its Subsidiaries that has
not been satisfied in full, and no condition exists that presents a material
risk of the Company or any Subsidiary incurring any such liability. With respect
to each Plan that is subject to Title IV of ERISA, the present value of accrued
benefits under such Plan, based upon the actuarial assumptions used for funding
purposes in the most recent actuarial report prepared with respect to such Plan,
did not, as of the valuation date used in such report, exceed the current value
of such Plan's assets allocable to such accrued benefits, and no material
adverse change in the funded status of any such Plan has occurred since such
valuation date. Full payment has been made of all amounts that the Company or
any of its Subsidiaries is required to pay under section 412 of the
<PAGE>
 
                                     - 13 -

Code or under the terms of the Plans. To the Seller's Knowledge, each Plan that
is intended to be "qualified" within the meaning of section 401(a) of the Code
is so qualified and each Plan that is intended to satisfy the requirements of
section 125 or 501(c) (9) of the Code satisfies such requirements. Each of the
Plans has been operated and administered in all material respects in accordance
with its terms and applicable laws. There are no actions, suits, claims, or
actions pending, or, to the Seller's Knowledge, threatened or anticipated (other
than routine claims for benefits) against any Plan or any related trust or
against the Company or any of its Subsidiaries. None of the Plans is the subject
of an audit, investigation, or examination by the IRS, Pension Benefit Guaranty
Corporation, Department of Labor or any other Governmental Entity. None of the
Plans is a multiemployer plan within the meaning of section 3(37) of
ERISA.

3.13.  Certain Contracts

       Neither the Company nor any Subsidiary is a party to, or is bound by, (i)
any material contract or any other contract pursuant to which any party thereto
has an obligation or commitment of greater than $3,000,000, (ii) any agreement
restricting the nature or geographic scope of its business activities in any
material respect, other than the Cooperation Agreement (iii) any agreement,
indenture or other instrument relating to the borrowing of more than $1,000,000
by the Company or any Subsidiary or the guarantee by the Company or any
Subsidiary of any such obligation, (iv) any agreement, arrangement or commitment
relating to the employment of a consultant who was formerly a director or
executive officer or the employment, election, retention in office or severance
of any present or former director or officer, or (v) any agreement, contract or
other instrument relating to or involving any swap, hedge or other similar off-
balance sheet transaction. Neither the Company nor any Subsidiary is in default
under any material agreement, commitment, arrangement, lease, insurance policy
or other instrument whether written or oral, and there has not occurred any
event (including the execution, delivery and performance of this Agreement or
any of the Related Agreements) that, with the lapse of time or giving of notice
or both, would constitute such a default, except for such defaults which would
not, individually or in the aggregate, have a Material Adverse Effect on the
Company.

3.14.  Legal Proceedings

       There are no actions, suits or proceedings instituted, pending or, to the
Seller's Knowledge, threatened (or unasserted but considered probable of
assertion) against the Seller, Company or any Subsidiary or against any asset,
interest or right of Seller, the Company or any Subsidiary which could have a
Material Adverse Effect on the Company and, to the Seller's Knowledge, there are
no other such actions, suits or proceedings instituted, pending or threatened
(or unasserted but considered probable of assertion). To the Seller's
Knowledge, there are no instituted, pending or threatened actions, suits or
proceedings that present a claim to restrain or prohibit the transactions
contemplated in this Agreement or any of the Related Agreements or to impose any
material liability in connection therewith.

3.15.  Labor and Related Matters

       Neither the Company nor any Subsidiary is a party to, or is bound by, any
contract, agreement or understanding with any labor union, organization, group
or association, and none of them has engaged in any unfair labor practice. Since
January 1, 1995, neither the Company nor any Subsidiary has experienced any
attempt by organized labor or its representatives to make the Company or any
Subsidiary conform to demands of organized labor relating to employees of the
Company or any Subsidiary or enter into a binding agreement with organized labor
that would cover employees of the Company or any Subsidiary. There is no pending
or threatened charge of unfair labor practice or any other action, complaint or
investigation by or before any Governmental Entity brought by or on behalf of
any employee, prospective employee or former employee of the Company or any
Subsidiary. There is no labor strike or labor disturbance pending against the
Company or any Subsidiary; and neither the Company nor any Subsidiary has
experienced any organized work stoppage or other labor difficulty since January
1, 1995. Neither the Company nor any Subsidiary is a party to or affected by or
threatened with any dispute or controversy with any supplier, subcontractor, or
customer, the outcome of which could have a Material Adverse Effect on the
Company.

3.16.  Brokers and Finders

       None of Seller, the Company, the Subsidiaries or any of their respective
officers, directors or employees, has employed any broker, finder or financial
advisor or

liabilities incurred in the ordinary course of business subsequent to December

any basis for the assertion of any such Liabilities.

       (b) There is no pending or threatened (or unasserted but considered
probable of assertion) Environmental Claim against or otherwise involving the
Company or any Subsidiary or any of their officers, directors, businesses or
assets nor, to the Seller's Knowledge, does any valid basis for such a claim or
controversy exist.  There is no judgment, order, injunction, award or consent
decree outstanding against or affecting the Company or any Subsidiary which
arises from or relates to an Environmental Claim.

       (c) The Environmental Properties are free from any and all contamination
by Materials of Environmental Concern for which material remedial action is

receiving any notice, letter, citation, order, warning, complaint, inquiry,
claim or demand alleging or asserting that:  (a) the Company or any Subsidiary
has violated, or is about to violate, any Environmental Laws; (b) there has been
a release or there is a threat of a release of any Material of Environmental
Concern at, from or onto any of the Environmental Properties; (c) the Company or
any Subsidiary may be or is liable, in whole or in part, for the costs of
cleaning up, remediating, removing or responding to a release or threat of a
release of any Material of Environmental Concern at, from or onto any of the
Environmental Properties or, as a result of its operation of such Environmental
Properties, at, from or onto any other property wherever located; or (d) any of
the Environmental Properties are subject to a lien in favor of any Governmental
Entity for any Damages, under Environmental Laws, arising from costs incurred by
such Governmental Entity.

3.18.  Intellectual Property

       (a) Seller has Previously Disclosed (i) all of the Intellectual Property
that has been registered in, filed in or issued by the United States Patent and
Trademark Office or the United States Copyright Office or any similar office in
any country and (ii) all Intellectual Property that is not so registered, filed
or issued, but the use of which is material to the ability of the Company to
operate the business of the Company and the Subsidiaries, taken as a whole.  The
Company or a Subsidiary is the sole and exclusive owner of the entire right,
title and interest in and to the Intellectual Property; neither the Company nor
any Subsidiary has granted, nor does there exist by implication or operation of
law, any license or other right in respect thereof which does or which will,
subsequent to the Closing, permit or enable any Person other than the Company
and the Subsidiaries to use the Intellectual Property, except for software
licenses granted by the Company or a Subsidiary to a distributor or an end user
customer in the ordinary course of business.  None of the Intellectual Property
is subject to any outstanding order, decree, judgment, stipulation, settlement,
lien, charge, encumbrance or attachment.  There is no pending or, to the
Seller's Knowledge, threatened (or unasserted but considered probable of
assertion) Claim (A) asserting that any of the Intellectual Property, or that
the past, present or contemplated future conduct of the Company's or its
Subsidiaries' business, infringes or violates the intellectual property rights
of any third parties,
<PAGE>
 
                                     - 17 -



(B) asserting that any third parties have any rights to use any of the
Intellectual Property or (C) which could, if adversely determined against the
Company or any Subsidiary, adversely affect the Company's ability to use any of
the Intellectual Property upon consummation of the transactions contemplated
hereby or thereafter, and to the Seller's Knowledge, there is no basis for any
claim of the foregoing types. Neither Seller nor the Company nor any Subsidiary
has given any notice to any third parties asserting infringement by such third
parties of any of the Intellectual Property. Neither the Company nor any
Subsidiary is subject to any bars or other restrictions with respect to its
rights to utilize any of the Intellectual Property, and, to the Seller's
Knowledge, no bars or other restrictions on such rights will be created by the
consummation of the transactions contemplated herein.

       (b) Seller has Previously Disclosed a list of all Intellectual Property
owned by third parties and licensed to the Company or any Subsidiary (the
"Licensed Intellectual Property").  All of the Licensed Intellectual Property is
licensed pursuant to valid written agreements (the "License Agreements"),
enforceable in accordance with their terms, except as may be limited by
bankruptcy, insolvency, moratorium or other similar laws affecting or relating
to the enforcement of creditors' rights generally and by general principles of
equity.  There is no pending or, to the Seller's Knowledge, threatened claim
that the Company, any Subsidiary or any licensor is in breach of any of the
License Agreements and, to the Seller's Knowledge, no basis for any such claim
exists.  There is no pending or, to the Seller's Knowledge, threatened claim
against the Company, any Subsidiary or the licensor of any Licensed Intellectual
Property asserting that any of the Licensed Intellectual Property infringes or
conflicts with the rights of third parties, or that the present, past or
contemplated future conduct of the business of the Company and its Subsidiaries
infringes or violates the rights of third parties, and to the Seller's
Knowledge, no basis for any such claim exists.

3.19.  Insurance

       The Company and each Subsidiary currently maintains insurance in amounts
reasonably necessary for its operations.  Such policies (i) are valid and
enforceable in accordance with their terms with financially sound and reputable
insurance companies and are in full force and effect, (ii) are sufficient for
compliance with all requirements of law and all agreements to which the
<PAGE>
 
                                     - 18 -



Company or any Subsidiary is a party or is subject, and (iii) provide insurance
coverage of the Properties, operations and employees of the Company and its
Subsidiaries generally comparable in type and amount to that which is
customarily carried by other corporations engaged in similar businesses. Neither
the Company nor any Subsidiary has received any notice of a premium increase or
cancellation with respect to any of its insurance policies or bonds, and within
the last three years, neither the Company nor any Subsidiary has been refused
any insurance coverage sought or applied for. The Company and the Subsidiaries
have no reason to believe that existing insurance coverage cannot be renewed as
and when the same shall expire, upon terms and conditions as favorable as those
presently in effect, other than possible increases in premiums or unavailability
in coverage that have not resulted from any extraordinary loss experience of the
Company or any Subsidiary.


                                   ARTICLE 4.

principles.

       (b) Thayer has all requisite partnership power and authority to enter

effect which affect the enforcement of creditors' rights generally and by
general equity principles.

       (d) Neither the execution and delivery of this Agreement nor consummation
of the transactions contemplated hereby, nor compliance by Thayer with any of
the provisions hereof, shall (i) conflict with or result in a breach of Thayer's

other instrument or obligation, or (iii) violate any order, writ, injunction,
decree, statute, rule or regulation applicable to Thayer, except (in the 
case of clauses (ii) and (iii) above) for such violations, rights, breaches,
Encumbrances or defaults which, either individually or in the aggregate, will
not have a Material Adverse Effect on Thayer.

       (e) No consent, approval or authorization of, or declaration, notice,
filing or registration with, any
<PAGE>
 
                                     - 20 -



Governmental Entity or any other Person, is required to be made or obtained by

anti-takeover laws and (ii) filings required pursuant to the HSR Act.

4.3.  Brokers and Finders

4.4.  Access; Sophistication

       Seller has provided to each Buyer copies of the Financial Statements and
each Buyer has reviewed such documents.  Each Buyer acknowledges that all
documents, books and records requested by such Buyer pertaining to the Company
or the Shares have been made available for inspection by such Buyer and his, her
or its agents and representatives; that such Buyer and his, her or its agents
and representatives have had a reasonable opportunity to ask questions of and
receive answers from Seller, the Company or officers or employees acting on
behalf of the Company and Seller, concerning the terms and conditions of the
offering of the Shares and the business and prospects of the Company.  Each
Buyer is an "accredited investor," as such term is defined in Rule 501 under the
Securities Act.  Each Buyer and his, her or its respective agents and
representatives have such knowledge and experience in financial and business
matters as to enable them to utilize the information made available to them in
connection with the transactions contemplated hereby, to evaluate the merits and
risks of an investment in the Shares and to make an informed decision with
respect thereto, and such an evaluation and informed decision have been made.
The questionnaires Previously Disclosed to Seller relating to each of the
Managers are accurate and complete in all material respects.

4.5.  Investment Representation

       Each Buyer is acquiring the Shares to be received by such Buyer at the
Closing for such person's own account for investment only and not with a view to
<PAGE>
 
                                     - 21 -



making a distribution thereof within the meaning of the Securities Act. Each
Buyer agrees not to sell or transfer such Shares, except in accordance with the
terms of the legend set forth below. Each Buyer is aware that the Shares have
not been registered under the Securities Act or any state or other
jurisdiction's securities laws, and that the Shares must be held indefinitely
unless subsequently registered or an exemption from such registration is
available. Each Buyer acknowledges that investment in the Shares involves
substantial risks, including the risk of total loss of his, her or its
investment in the Shares. Each Buyer represents that he, she or it (i) is able
to hold the Shares for an indefinite period of time; (ii) has adequate means,
other than the Shares or funds invested therein, of providing for his, her or
its current and foreseeable needs; (iii) has no foreseeable need to sell or
otherwise dispose of any of the Shares; and (iv) has sufficient net worth to
sustain a loss of his, her or its entire investment in the Shares in the event
such loss should occur. Each Manager is a bona fide resident of Virginia,
Maryland, or the District of Columbia and has no present intention of changing
his or her residence. Each Buyer understands and agrees that the certificate or
certificates representing the Shares to be received by such Buyer will bear a
legend substantially to the effect set forth below and that a stop transfer
order may be placed with respect thereto.

       THE SHARES OF COMMON STOCK REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN
       REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED, OR ANY
       APPLICABLE SECURITIES LAW OF ANY JURISDICTION AND MAY NOT BE TRANSFERRED
       UNTIL (A) A REGISTRATION STATEMENT UNDER SUCH SECURITIES ACT AND SUCH
       APPLICABLE SECURITIES LAWS SHALL HAVE BECOME EFFECTIVE WITH REGARD
       THERETO OR (B) IN THE OPINION OF COUNSEL REASONABLY ACCEPTABLE TO THE
       COMPANY, REGISTRATION UNDER SUCH SECURITIES ACT AND SUCH APPLICABLE
       SECURITIES LAWS IS NOT REQUIRED IN CONNECTION WITH SUCH PROPOSED
       TRANSFER.

Notice at the price and on the terms specified in such notice, provided that (i)

6.1.  Indemnification by Seller

      Subject to the limitations set forth in Sections 6.4 and 6.5 hereof,
Seller hereby indemnifies and holds harmless Buyers and their respective
affiliates, directors, officers, employees and agents from and against any and
all Damages (other than consequential and punitive damages that do not result
from third party Claims) arising out of, based upon or with respect to:

           (i)    any breach of any representation or warranty made by Seller in
      this Agreement or the Related Agreements or any material misrepresentation
      in or omission from any certificate, schedule, exhibit or other document
      delivered to Buyers pursuant to this Agreement or the Related Agreements;
      or

           (ii)   any failure, on the part of the Company prior to the Closing
      and on the part of
<PAGE>
 
                                     - 28 -


      Seller at any time, to perform any material covenant, agreement or
      undertaking contained in this Agreement or the Related Agreements.

6.2.  Indemnification By Buyers

      Subject to the limitations set forth in Sections 6.4 and 6.5 hereof,
Buyers hereby jointly and severally indemnify and hold harmless Seller and each
of its affiliates, directors, officers, employees and agents from and against
any and all Damages (other than consequential and punitive damages that do not
result from third party Claims) arising out of, based upon or with respect to:

           (i)    any breach of any representation or warranty made by Buyers in
      this Agreement or the Related Agreements or any material misrepresentation
      in or omission from any certificate, schedule, exhibit or other document

      or

           (ii)   any failure of Buyers to perform any material covenant,

      Related Agreements.

6.3.  Indemnification Procedures

      (a)  Promptly after the occurrence of any event or the discovery of any
facts which could give rise to a right to indemnification under this Article 6,
the person who may be entitled to indemnification (the "Indemnified Person")
shall promptly give notice to the Party required to indemnify the Indemnified
Person (the "Indemnitor"), in writing, describing in reasonable detail the facts
and circumstances giving rise to the claim for indemnification, the Damages
suffered or incurred, including the amount of such Damages, if known, or as
estimated, and the provisions of this Agreement relating to such claim for
indemnification.  The failure of an Indemnified Person to give prompt notice in
the manner provided herein shall not relieve the Indemnitor of its obligations
under this Article 6, except to the extent that the Indemnitor is actually
prejudiced by such failure to give prompt notice.  Upon receipt of a notice of a
claim for indemnification, the Indemnitor shall promptly pay to the Indemnified
Person the amount of such Damages in accordance with and subject to the
provisions of this Article 6; provided, however, that no such payment shall
<PAGE>
 
                                     - 29 -

be due during any period in which the Indemnitor is contesting in good faith
either its obligation to make such indemnification or the amount of Damages
payable.

      (b)  If any Claim is instituted by a third party with respect to which an
Indemnified Person intends to, or may be entitled to, claim a right to
indemnification under this Article 6, the Indemnified Person shall promptly
notify the Indemnitor of such Claim.  The failure of an Indemnified Person to
give notice in the manner provided herein shall not relieve the Indemnitor of
its obligations under this Article 6, except to the extent that the Indemnitor
is actually prejudiced by such failure to give notice.  The Indemnitor shall
have the right to control, at its expense and through counsel of its choosing,
the defense of any such third party Claim, but may compromise or settle the same
only with the consent of the Indemnified Person, which consent shall not be
unreasonably withheld.  The Indemnified Person shall cooperate fully with the
Indemnitor and its counsel in the defense of any such third party Claim and
shall make available to the Indemnitor any books, records or other documents
within its control that are necessary or appropriate for such defense.  After
providing notice of its intent to exercise its right to control such defense,
the Indemnitor shall not be responsible for any legal or other expenses
subsequently incurred by the Indemnified Person in connection therewith;
provided, however, that an Indemnified Person shall have the right to control
its defense of any such third party Claim and retain its own counsel, with the
reasonable fees and expenses to be paid by the Indemnitor, if such Indemnitor
shall have consented to such retention of counsel or the Indemnified Party shall
have reasonably concluded that representation of such Indemnified Person by the
counsel retained by the Indemnitor would be inappropriate due to actual or
potential differing interests between such Indemnified Person and any other
party represented by such counsel in such proceeding.

      (c)  At no time may an Indemnitor assert as a defense to its obligation
to provide indemnification as set forth in this Article 6 that, prior to the
Closing, the Indemnified Person or any of its employees, agents or affiliates
had any knowledge of the matter to which the claim for indemnification relates,
or conducted any investigation relating thereto, and each Party hereby
irrevocably waives all such defenses.

6.4.  Limitations on Recoveries

      Notwithstanding anything to the contrary contained herein, no
indemnification claim under this Article 6 shall be (i) enforced against any
Indemnitor to the extent any insurance proceeds or other recoveries actually are
received by the Indemnified Person with respect to any Damages otherwise payable
by the Indemnitor or (ii) valid against an Indemnitor unless a written notice
pursuant to Section 6.3 of this Agreement (a "Claims Notice") has been delivered
to such Indemnitor with respect to such claim.

6.5.  Remedies for Damages

      The right to indemnification under this Article 6 constitutes an
Indemnified Person's sole remedy for damages with respect to the breach of any
representation or warranty contained in this Agreement.  In circumstances where
Seller is the Indemnitor, an Indemnified Person shall have the right to seek
indemnification under this Article either (i) directly from Seller or (ii)
indirectly from Seller by causing the Company to (x) pay such indemnification
claim and (y) make a corresponding deduction in the amount payable or to be paid
by the Company to Seller pursuant to the Cooperation Agreement. In circumstances
where the Seller is the Indemnitor, the Indemnified Person shall specify in its
Claims Notice the indemnification source from which the Indemnified Person
intends to recover.

8.1.  Termination

      This Agreement may be terminated and the transactions contemplated hereby
abandoned at any time prior to the Closing Date, only as follows:

      (a)  By the mutual consent in writing of Seller and Thayer;

      (b)  By Thayer in writing, if Seller or the Company has, or by Seller in
writing, if any Buyer has, in any material respect, breached (i) any covenant or
agreement contained herein or (ii) any representation or warranty contained
herein, and in either case if such breach has not been cured by the earlier of
15 business days after the date on which written notice of such breach is given
to the Party committing such breach or the Closing Date;

      (c)  By any party hereto in writing, if the Closing Date has not occurred
by the close of business on May 1, 1997, unless the failure of the Closing to
occur by such date shall be due to the failure of the Party seeking to terminate
this Agreement to perform or observe the covenants and agreements set forth
herein; or

      (d)  By Seller or Thayer in writing, if any Governmental Entity of
competent jurisdiction shall have issued a final non-appealable order enjoining
or otherwise prohibiting the transactions contemplated hereby.

8.2.  Effect of Termination

      In the event this Agreement is terminated pursuant to Section 8.1 hereof,
this Agreement shall become void and have no effect, provided, however, that
nothing herein shall relieve any Party from liability for the breach of any
representations or warranties or the breach of, or failure to perform, any
covenant made by it herein.

                                 MISCELLANEOUS

9.1.  Survival of Representations and Warranties

      The representations, warranties and covenants contained in this Agreement
shall survive the Closing and any and all investigations and inquiries by the
Parties made prior to the Closing Date in connection with this Agreement and the
transactions contemplated hereby.  The representations, warranties, covenants
and agreements of the Parties contained in this Agreement and the Related
Agreements shall not be affected by or diminished in any way by any
investigation (or failure to investigate) made at any time by or on behalf of
the Party for whose benefit such representations, warranties, covenants and
agreements were made.

9.2.  Amendment

      This Agreement may be amended or supplemented at any time by the mutual
agreement in writing of Seller, the Company and Thayer.  Seller and the Company
agree to approve, execute and deliver any amendment to this Agreement and any
additional plans and agreements requested by Thayer to modify the structure of,
or to substitute parties to, the transactions contemplated hereby; provided,
however, that no such change shall (i) alter or change the amount or kind of
consideration to be delivered to the Seller in connection with the transactions
contemplated hereby, or (ii) materially impede or delay the consummation of the
transactions contemplated by this Agreement.  Notwithstanding anything to the
contrary herein, Thayer shall have the right, at any time prior to the Closing,
to modify or amend Exhibit A hereto without the consent of any other party
hereto, provided that (x) Thayer shall provide notice of any such amendment or
modification to all the other parties hereto and (y) no such amendment or
modification shall increase the Equity Contribution of any Manager without such
Manager's consent.

9.3.  No Waiver of Rights

      No failure or delay on the part of any Party in the exercise of any power
or right hereunder shall operate as a waiver thereof.  No single or partial
exercise of any right or power hereunder shall operate as a waiver of such right
or of any other right or power.  The waiver by any Party of a breach of any
provision of this Agreement shall not operate or be construed as a waiver of any
other or

                                    - 35 -


subsequent breach hereunder. Except as otherwise expressly provided herein, all
rights and remedies existing under this Agreement are cumulative with, and not
exclusive of, any rights or remedies otherwise available.

       Each Party hereto shall bear and pay all costs and expenses incurred by
it in connection with the transactions contemplated in this Agreement, including
fees and expenses of its own financial consultants, accountants and counsel.

9.5.   Entire Agreement; Successors; Third Parties

       This Agreement and the Related Agreements contain the entire agreement
between the Parties with respect to the transactions contemplated hereunder and
thereunder and supersede all prior arrangements or understandings with respect
thereto, written or oral, other than documents referred to herein or therein.
The terms and conditions of this Agreement shall inure to the benefit of and be
binding upon the Parties hereto and their respective successors and permitted
assigns.  Except as specifically set forth herein or in any Related Agreement,
nothing in this Agreement or any Related Agreement, expressed or implied, is
intended to confer upon any party, other than the parties hereto and thereto,
and their respective successors and permitted assigns, any rights, remedies,
obligations or liabilities.

9.6.   No Assignment

       No Party hereto may assign any of its rights or obligations under this
Agreement to any other Person, except that Thayer may assign its rights and/or
obligations to an affiliate of Thayer.

       The captions contained in this Agreement are for reference purposes only
and are not part of any such agreement.

9.9.   Counterparts

court chosen in such manner for such action.

9.11.  Severability

       The provisions of this Agreement are severable, and the unenforceability
of any provision of this Agreement shall not affect the enforceability of the
remainder of this Agreement. The parties acknowledge that it is their intention
that if any provision of this Agreement is determined by a court to be invalid,
illegal or unenforceable as drafted, that provision should be construed in a
manner designed to effectuate the purpose of that provision to the greatest
extent possible under applicable law.

9.12.  Specific Performance

       The rights of the Parties under this Agreement and the Related Agreements
are unique and the failure of a Party to perform its obligations hereunder or

in equity, have the right to enforce their rights hereunder by actions for
specific performance to the extent permitted by law.

                                  ARTICLE II
                    PURCHASED SECURITIES AND PURCHASE PRICE

2.01     Purchase of Purchased Securities.

On the terms and subject to the conditions of this Agreement, the Buyer agrees
to purchase from the Seller, and the Seller agrees to sell and deliver to the
Buyer, on the Closing Date, all right, title, and interest of the Seller in and
to the Purchased Securities, being all of the issued and outstanding securities
in the capital of the Corporation as of the Closing Date.

2.02     Purchase Price.

The aggregate purchase price for the Purchased Securities (the "Purchase Price")
shall be $14,000,000.

2.03     Payment of Purchase Price.

On the Closing Date, against delivery by the Seller of certificates evidencing
the Purchased Securities duly endorsed for transfer and accompanied by
instruments of transfer in the manner contemplated by this Agreement, and upon
satisfaction of all other terms and conditions to be satisfied by the Seller and
the Principals hereunder, the Buyer shall pay the Purchase Price to the Seller.
The Purchase Price shall be paid by or on behalf of the Buyer as to $7,000,000
by wire transfer in same day available funds to the Seller on the Closing Date,
and the balance of the Purchase Price shall be paid upon the terms and
conditions of the Note which shall be delivered by the Buyer to the Seller on
the Closing Date.

2.04     Special Dividend and Special Share Redemption.

The Buyer acknowledges that, prior to the Closing Date:

         1.      the Corporation shall pay to the Seller the Special Dividend
                 in cash on its common shares;
         
         2.      the Special Share is redeemable prior to the Closing Date for
                 an amount equal to 75% of the dividend refund received
                 pursuant to subsection 129(1) of the Income Tax Act (Canada)
                 by the Corporation in respect of dividends paid by it prior to
                 the Closing Date as more particularly set forth in the terms
                 and conditions of the
<PAGE>
 
                                     --10--

           Special Share contained in the articles of the Corporation (the
           "Dividend Refund"); and

     3.    the Corporation shall redeem the Special Share prior to the Closing
           Date for $773,500 by payment in cash.

The Buyer and Seller hereby acknowledge and agree that the Dividend Refund may
be subject to adjustment in the event that there shall be issued to the
Corporation a notice of assessment or reassessment pursuant to any taxing
statute, which assessment or reassessment is based upon a determination that the
Corporation was not entitled to the Dividend Refund or to some portion thereof.
Neither the Corporation nor the Buyer shall have any obligation to appeal such
assessment but the Principals and the Seller shall be able to contest such
assessment or reassessment at their own expense. In this event, the Dividend
Refund shall be deemed to be and to have always been the amount of the dividend
refund ultimately determined by the taxing authority. In the event that the
Redemption Amount is subsequently adjusted in accordance with the terms of the
Special Share as a result of an assessment or reassessment under a taxing
statute relating to the Dividend Refund, the Seller shall pay to the
Corporation, or the Corporation shall pay to the Seller, as the case may be,
within 30 days of the Corporation receiving notice from the taxation authority
of such adjustment such amount as shall be required to ensure that the Seller
has received and retained an amount equal to the Redemption Amount as so
adjusted. The Buyer shall have the right to set-off any obligations owing by the
Seller to the Corporation pursuant to this Section 2.04 against any amounts
owing by the Buyer to the Seller under the Note or otherwise under this
Agreement or any Ancillary Agreement, and the indemnities provided by the Seller
and the Principals to the Buyer under Article IX shall extend to and
specifically include any obligations of the Seller to the Corporation pursuant
to this Section 2.04.

2.05   Removal.

The Buyer acknowledges that Seller shall be entitled, on or prior to the Closing
Date, to remove the Excluded Assets from the Corporation and obtain full
ownership thereof.

2.06   AG Amalgamation.

The Seller and Principals acknowledge that the Buyer shall be entitled to
complete a short-form vertical amalgamation of the Buyer and the Corporation on
or forthwith following the Closing Date pursuant to the provisions of the OBCA
whereupon the RD Guarantee and RD Security Agreement shall terminate and the 
AG Security Agreement shall continue in full force and effect to secure the
obligations due under the Note and the Other Obligations.

2.07   Royalty Repayment.

The Buyer and the Guarantor acknowledge that the Subsidiary was credited in the
amount of $1,500,000 (the "Credit") by the Guarantor in respect of estimated
royalties due to the Corporation as a result of certain sales of the
Corporation's Owned Software Programs in jurisdictions outside of North America
up to the Closing Date (the "Foreign Royalties"). The
<PAGE>
 
                                     --11--

countries and the periods of time in respect of which such Credit has been
granted and the allocation of the Credit among them is set forth in 
Schedule "7". The Guarantor shall, after the Closing Date, use reasonable
commercial efforts to collect ("collect", "collection" and "collected" including
the exercise of rights of set-off in respect of, or the obtaining of other
equivalent compensation for) Foreign Royalties and, in doing so, shall use
currently available site audit procedures for license compliance customary in
the industry. The Guarantor shall provide the Seller with semi-annual reporting,
by March 31, 1998 and September 30, 1998, as to Foreign Royalties collected and
the efforts made by the Guarantor to do so. In the event that the actual amount
of Foreign Royalties due to the Corporation (determined in accordance with
current practice and based upon the royalties actually collected by the
Guarantor) in respect of the countries and the periods of time identified in
Schedule "7", exceeds the amount of the Credit, the Guarantor and the
Corporation shall pay such excess amount to the Seller within 30 days following
the final determination of the actual amount of such Foreign Royalties collected
by the Guarantor. In the event that the Guarantor collects Foreign Royalties
which relate to countries and/or periods of time other than those identified in
Schedule "7" due to the Corporation (determined in accordance with current
practice and based upon the royalties actually collected by the Guarantor), the
Guarantor shall pay such Foreign Royalties collected, that would have otherwise
been payable to the Corporation, to the Seller. Such payments shall be made in
full within 30 days following the collection by the Guarantor of such Foreign
Royalties. In the event that the Seller disagrees with the calculation by the
Corporation and/or the Guarantor of the amount of Foreign Royalties collected or
the amount due to the Seller hereunder (if any), the Seller may, at its own
expense, audit the records of the Guarantor and the Corporation relating to the
collection of Foreign Royalties and related records on reasonable notice and
during normal business hours. Any difference between the amount actually paid by
the Corporation and/or the Guarantor to the Seller hereunder and the amount
determined upon such audit to have been collected by the Guarantor and/or the
Corporation shall be payable by the Corporation and/or the Guarantor to the
Seller, or by the Seller to the Corporation and/or the Guarantor, as the case
may be. In the event that, as a result of such audit, the Corporation and/or the
Guarantor is required to pay to the Seller an amount in excess of 5% of the
amount previously paid by the Corporation and/or the Guarantor to the Seller
hereunder, the Corporation and/or the Guarantor shall reimburse the Seller for
the cost of such audit up to a maximum of $10,000. The payment and performance
by the Corporation of its obligations (if any) to pay such amount hereunder
shall be secured pursuant to the guarantees and security of the Guarantor, the
Buyer and the Corporation forming part of the Ancillary Documents. The
Corporation shall cease to have any obligation hereunder after November 30, 1998
provided that such final determination has been made as of September 30, 1998,
the reports required hereunder have been provided to the Seller, and any amounts
due to the Seller hereunder have been paid. The Seller shall thereafter have the
right, in consultation with the Guarantor, acting reasonably (and the Guarantor
having no obligation to assist the Seller) to directly pursue the collection of
unpaid Foreign Royalties, at its own cost and expense, until March 3 1, 1999 if
it determines, acting reasonably, that additional amounts may be payable.

3.27     Taxes and Filings.

The Corporation has filed or caused to be filed, within the times and within the

full, true and complete copies of such returns and reports for the past 3 fiscal
years have been provided to the Buyer. To their knowledge all federal,
provincial, local and foreign income, profits, franchise, sales, use, occupancy,
excise and other taxes and assessments (including interest and penalties)
payable by or due from the Corporation have been fully paid or are adequately
disclosed and fully provided for in the books and records and the Financial
Statements or the Interim Financial Statements (except as set forth in Section
3.23(b) above) as the case may be. The federal income tax liability of the
Corporation has been assessed for all fiscal years up to but excluding its
current fiscal year. No field audit of any tax return is currently in progress
nor has the Corporation been notified in writing that any tax returns previously
filed by it will be subject to reassessment. There are no outstanding agreements
or waivers extending the statutory period of limitation applicable to any tax
return of the Corporation, except in respect of the fiscal years 1991 through

development tax credit claim of the Predecessor Corporation for the fiscal year
ended November 30, 1995 and the prior years was reassessed (and details of such
reassessment have been provided to the Buyer) by Revenue Canada, Taxation and
that the corresponding Ontario and Alberta claims have not yet been assessed by
the Ontario and Alberta Ministries of Revenue and the amount of such claims may
be reduced upon such assessments. The Corporation records scientific research
and experimental development tax credits on its financial statements only when
and to the extent the same was applied against income taxes otherwise payable
and the future tax benefit to the Corporation regarding such claims is not
recorded on the Financial Statements or the Interim Financial Statements. The
Buyer agrees that neither the Seller nor the Principals shall have any liability
pursuant to this Section 3.27 in respect of assessments or potential
reassessments of federal or provincial scientific research and experimental
development tax credits claimed until the amount of such liability exceeds the
amount of the Corporation's scientific research and experimental development tax
credit carry-forward as at the date hereof.

      officer or employee of the Corporation the obligation of the Corporation
      to make such payment shall terminate and the amount otherwise payable to
      such employee shall be allocated among such other employees of the

<PAGE>
 
                                     --40--

the Principals or the Seller as a result of, in respect of, connected with or

                  any Ancillary Agreement.

9.04     Indemnification Proceedings.

(1)  Any Party seeking indemnification under this Article (the "indemnified
party") shall forthwith notify the Party against whom a Claim for
indemnification is sought hereunder (the "indemnifying party") in writing, which
notice shall specify, in reasonable detail, the nature and estimated amount of
the Claim provided that, in so doing, it may restrict or condition any
disclosure in the interest of preserving privileges of importance in any
foreseeable litigation. If a Claim by a third party is made against an
indemnified party, and if the indemnified party intends to seek indemnity with
respect thereto under this Article, the indemnified party shall promptly (and in
any case within 15 days of such Claim being made) notify the indemnifying party
of such with reasonable particulars. The indemnifying party shall have 30 days
after receipt of either such notice to undertake, conduct and control, through
counsel of its own choosing and at its expense, the settlement or defence
thereof, and the indemnified party shall co-operate with it in connection
therewith; except that with respect to settlements entered into by the
indemnifying party (i) the consent of the indemnified party shall be required if
the settlement provides for equitable relief against the indemnified party,
which consent shall not be unreasonably withheld or delayed; and (ii) the
indemnifying party shall obtain the release of the indemnified party. If the
indemnifying party undertakes, conducts and controls the settlement or defence
of such Claim (i) the indemnifying party shall permit the indemnified party to
participate in (subject to the indemnifying party's right to conduct and
control) such settlement or defence through counsel chosen by the indemnified
party, provided that the fees and expenses of such counsel shall be borne by the
indemnified party; and (ii) the indemnifying party shall promptly reimburse the
indemnified party for the full amount of any loss resulting from any Claim and
all related expenses (other than the fees and expenses of counsel as aforesaid)
incurred by the indemnified party upon the final settlement or adjudication of
such claims. The indemnified party shall not pay or settle any Claim so long as
the indemnifying party is reasonably contesting any such Claim in good faith on
a timely basis. Notwithstanding the two immediately preceding sentences, the
indemnified party shall have the right to pay or settle any such Claim, provided
that in such event it shall waive any right to indemnity therefor by the
indemnifying party.

(2)  With respect to third party Claims, if the indemnifying party does not
notify the indemnified party within 30 days after the receipt of the indemnified
party's notice of a Claim of indemnity hereunder that it elects to undertake the
defence thereof, the indemnified party shall have the right, but not the
obligation, to contest, settle or compromise the Claim in the exercise of its
reasonable judgement at the expense of the indemnifying party.
<PAGE>
 
                                     --41--

(3)      In the event of any Claim by a third party against an indemnified
party, the defence of which is being undertaken and controlled by the
indemnifying party, the indemnified party will use all reasonable efforts to
make available to the indemnifying party those employees whose assistance,
testimony or presence is necessary to assist the indemnifying party in
evaluating and in defending any such Claims; provided that the indemnifying
party shall be responsible for the expense associated with any employees made
available by the indemnified party to the indemnifying party hereunder, which
expense shall be equal to a reasonable amount to be mutually agreed upon per
person per hour or per day for each day or portion thereof that such employees
are assisting the indemnifying party and which expenses shall not exceed the
actual cost to the indemnified party associated with such employees.

(4)      With respect to third party Claims, the indemnified party shall make
available to the indemnifying party or its representatives on a timely basis all
documents, records and other materials in the possession of the indemnified
party, at the expense of the indemnifying party, reasonably required by the
indemnifying party for its use in defending any Claim and shall otherwise
co-operate on a timely basis with the indemnifying party in the defence of such
Claim.

(5)      With respect to any re-assessment for income, corporate sales, excise,
or other tax or other liability enforceable by Encumbrance against the property
of the indemnified party, the indemnifying party's right to so contest shall
only apply after the payment of such re-assessment or the provision of such
security, in each case as is necessary to avoid an Encumbrance being placed on
the property of the indemnified party, or the taking of such other steps as are
acceptable to the indemnified party, acting reasonably.

(6)      In the event that the indemnified party and indemnifying party do not
agree as to the amount of a Claim asserted hereunder with respect to a breach of
a representation or misrepresentation under this Agreement within a period of 30
days following notification of such Claim, and the amount of such Claim
(together with all other Claims in respect of which indemnification has been
sought), exceeds $100,000, either of the parties shall be entitled forthwith
thereafter to refer all of such Claims in dispute to arbitration before a single
arbitrator in Toronto, Ontario pursuant to the provisions of the Arbitration Act
(Ontario) which determination shall be final, conclusive and binding on the
parties with respect to the subject matter of such Claim. The party prevailing
in such proceeding shall be entitled to be reimbursed for all of its costs and
expenses incurred in connection therewith by the other party in addition to such
other relief as may be granted as a result of such proceeding.

9.05     Limitations.

Notwithstanding anything in this Article IX to the contrary:

(a)      Maximum Liability. The total liability of the Seller and the Principals
to the Buyer and the Guarantor for indemnification pursuant to this Article IX,
exclusive of Claims based on any breach of the representations and warranties
contained in Section 3.27, the covenants and agreements of the Seller contained
in this Agreement, or if attended by fraud or any knowing or willful breach
<PAGE>
 
                                     --42--

thereof, any other representations and warranties, shall not exceed $4,000,000;
but the liability of the Seller and the Principals to the Buyer for
indemnification for Claims based on tax matters under Section 3.27 and such
other excluded matters shall not be limited in amount. Notwithstanding the
foregoing, no Claims may be made until the aggregate of the Claims of the Buyer
and the Guarantor exceed $25,000, but in such event the entire amount of such
Claims may be sought.

(b)      Exclusive Remedy. The Parties hereto acknowledge and agree that this
Article IX is the exclusive remedy of the parties hereto for damages for breach
or misrepresentation of or under this Agreement. This provision is not intended
to preclude any proceeding by any Party against any other Party based on a cause
of action or right, including any statutory right, other than a cause of action
in contract for breach of a representation, warranty or agreement contained in
this Agreement provided that (i) such Claim involves an amount in excess of
$250,000; (ii) such Claim must be made within a period of two years following
the date hereof; and (iii) the aggregate liability of the Seller or the
Principals in respect of such Claim shall not exceed the $4,000,000 limitation
set forth in 9.05(a) after taking into account all Claims made for breaches of
representations as of the date of such Claim. In the event of any such Claim,
the Principals and the Seller shall have the benefit of (i) the provisions of
this Article IX in the event of Claims as to procedural matters based on third
party claims; and (ii) the arbitration provisions of Section 9.04(6).

                                    ARTICLE X

the Company.


3.  Administration
    --------------

       The Committee shall administer the Plan and shall have plenary authority,
in its discretion, to award Options to Eligible Individuals, subject to the
provisions of the Plan.  The Committee shall have plenary authority and
discretion, subject to the provisions of the Plan, to determine the terms (which

Eligible Individuals shall be granted Options, the time or times at which
Options are granted, the Option Price, the number of Shares subject to an
Option, whether an Option shall be an Incentive Stock Option or a Nonstatutory
Stock Option, any provisions relating to vesting, any circumstances in which
Options terminate or Shares may be repurchased by the Company, the period during
which Options may be exercised and any other restrictions on Options.  In making
these determinations, the Committee may take into account the nature of the
services rendered by the Optionees, their present and potential contributions to
the success of the Company and its Affiliates, and such other factors as the
Committee in its discretion shall deem relevant.  Subject to the provisions of
the Plan, the Committee shall have plenary authority to construe and interpret
the Plan and the Agreements, to prescribe, amend and rescind rules and
regulations relating to the Plan and to make all other determinations deemed

       5.2.  If an Option expires or terminates for any reason without having
been fully exercised, the unissued Shares which had been subject to such Option
shall become available for the grant of additional Options.


6.   Options
     -------

       6.1.  Options granted under the Plan shall be either Incentive Stock
Options or Nonstatutory Stock Options, as designated by the Committee.  Each
Option granted under the Plan shall be clearly identified either as an Incentive
Stock Option or a Nonstatutory Stock Option and shall be evidenced by an
Agreement that specifies the terms and conditions of the grant. Options granted
to Eligible Individuals shall be subject to the terms and conditions set forth
in this Article 6 and such other terms and conditions not inconsistent with this
Plan as the Committee may specify.  All Incentive Stock Options shall comply
with the provisions of the Code governing incentive stock options and with all
other applicable rules and regulations.

       6.2.  The Option Period for Options granted to Eligible Individuals shall
be determined by the Committee and specifically set forth in the Agreement,
provided, however, that an Option shall not be exercisable after ten years (five
years in the case of an Incentive Stock Option granted to a Ten-Percent
Stockholder) from its Date of Grant.


7.   Exercise of Options
     -------------------

       7.1.  An Option may, subject to the terms of the applicable Agreement
under which it is granted, be exercised in whole or in part by the delivery to
the Company of written notice of the exercise, in such form
<PAGE>
 
                                      -5-

as the Committee may prescribe, accompanied by full payment of the Option Price
for the Shares with respect to which the Option is exercised as provided in
Section 7.2 hereof.

       7.2.  Payment of the aggregate Option Price for the Shares with respect
to which an Option is being exercised shall be made in cash; provided, however,
that the Committee, in its sole discretion, may provide in an Agreement that
part or all of such payment may be made by the Optionee in one or more of the
following manners: (a) by delivery (including constructive delivery) to the
Company of Shares valued at Fair Market Value on Date of Exercise; (b) by
delivery on a form prescribed by the Committee of a properly executed exercise
notice and irrevocable instructions to a registered securities broker approved
by the Committee to sell Shares and promptly deliver cash to the Company; (c) by
delivery of a promissory note as provided in Section 7.3 hereof; or (d) by
surrender to the Company of an Option (or a portion thereof) that has become
exercisable and the receipt from the Company upon such surrender, without any
payment to the Company (other than required tax withholding amounts), of (x)
that number of Shares (equal to the highest whole number of Shares) having an
aggregate Fair Market Value as of the date of surrender equal to that number of
Shares subject to the Option (or portion thereof) being surrendered multiplied
by an amount equal to the excess of (i) the Fair Market Value on the date of
surrender over (ii) the Option Price, plus (y) an amount of cash equal to the
Fair Market Value of any fractional Share to which the Optionee would be
entitled but for the parenthetical in clause (x) above relating to whole number
of Shares.

       7.3.  To the extent provided in an Option Agreement and permitted by
applicable law, the Committee may accept as payment of the Option Price a
promissory note executed by the Optionee evidencing his or her obligation to
make future cash payment thereof; provided, however, that in no event may the
Committee accept a promissory note for an amount in excess of the difference
between the aggregate Option Price and the par value of the Shares.  Promissory
notes made pursuant to this Section 7.3 shall be payable upon such terms as may
be determined by the Committee, shall be secured by a pledge of the Shares
received upon exercise of the Option and shall bear interest at a rate fixed by
the Committee.

8.   Restrictions on Transfer
     ------------------------

       Except as set forth in an Agreement, Options shall not be transferable
other than by will or the laws of descent and distribution, and an Option may be
exercised during the Optionee's lifetime only by the Optionee or, in the event
of his or her legal disability, by his or her legal representative. The Shares
acquired pursuant to the Plan shall be subject to such restrictions and
agreements regarding sale, assignment, encumbrances, or other transfers or
dispositions thereof (i) as are in effect among the stockholders of the Company
at the time such Shares are acquired, (ii) as the Committee shall deem
appropriate and (iii) as are required by applicable law.


9.   Capital Adjustments
     -------------------

       In the event of any change in the outstanding Common Stock by reason of
any stock dividend, split-up (or reverse stock split), recapitalization,
reclassification, reorganization, reincorporation, combination or exchange of
shares, merger, consolidation, liquidation or similar change in corporate
structure, the Committee may, in its discretion, provide for a substitution for
or adjustment in (i) the number and class of Shares subject to outstanding
Options, (ii) the Option Price of outstanding Options, and (iii) the aggregate
number and class of Shares that may be issued under the Plan.


10.  Termination or Amendment
     ------------------------

       The Board may amend, alter, suspend or terminate the Plan in any respect
at any time; provided, however, that after the Plan has been approved by the
stockholders of the Company, no amendment, alteration, suspension or termination
of the Plan shall be made by the Board without approval of (i) the Company's
stockholders to the extent stockholder approval is required by applicable law or
regulations and (ii) each affected Optionee if such amendment, alteration,
suspension or termination would adversely affect his or her rights or
obligations under any Option granted prior to the date of such amendment,
alteration, suspension or termination.  No Option may be granted nor any Shares
issued under the Plan during any suspension or after termination of the Plan.

11.  Modification, Extension and Renewal of Options; Substituted Options
     -------------------------------------------------------------------

       11.1.  Subject to the terms and conditions of the Plan, the Committee may
modify, extend or renew the terms of any outstanding Options, or accept the
surrender of outstanding Options granted under the Plan or options and stock
appreciation rights granted under any other plan of the Company or an Affiliate
(to the extent not theretofore exercised) and authorize the granting of new
Options in substitution therefor (to the extent not theretofore exercised).  Any
such substituted Options may specify a lower exercise price than the surrendered
options and stock appreciation rights, a longer term than the surrendered
options and stock appreciation rights, or have any other provisions that are
authorized by the Plan.  Notwithstanding the foregoing, however, no modification
of an Option shall, without the consent of the Optionee, alter or impair any of
the Optionee's rights or obligations under such Option.

       11.2.  Anything contained herein to the contrary notwithstanding, Options
may, at the discretion of the Committee, be granted under the Plan in
substitution for stock appreciation rights and options to purchase shares of
capital stock of another corporation which is merged into, consolidated with, or
all or a substantial portion of the property or stock of which is acquired by,
the Company or one of its Affiliates.  The terms and conditions of the
substitute Options so granted may vary from the terms and conditions set forth
in this Plan to such extent as the Committee may deem appropriate in order to
conform, in whole or part, to the provisions of the options and stock
appreciation rights in substitution for which they are granted.


12.  Effectiveness of the Plan
     -------------------------

       The Plan and any amendment thereto shall be effective on the date on
which it is adopted by the Board, provided that any such adoption requiring
stockholder approval is subject to approval by vote of the stockholders of the
Company within 12 months after such adoption by the Board.  Options may be
granted prior to stockholder approval of the Plan, and the date on which any
such Option is granted shall be the Date of Grant for all purposes provided that
(a) each such Option shall be subject to stockholder approval of the Plan, (b)
no Option may be exercised prior to such
<PAGE>
 
                                      -8-

stockholder approval, and (c) any such Option shall be void ab initio if such
stockholder approval is not obtained.


13.  Withholding
     -----------

       The Company's obligation to deliver Shares or pay any amount pursuant to
the terms of any Option shall be subject to the satisfaction of applicable
federal, state and local tax withholding requirements.  To the extent provided
in the applicable Agreement and in accordance with rules prescribed by the
Committee, an Optionee may satisfy any such withholding tax obligation by any of
the following means or by a combination of such means: (i) tendering a cash
payment, (ii) authorizing the Company to withhold Shares otherwise issuable to
the Optionee, or (iii) delivering to the Company already owned and unencumbered
Shares.


14.  Term of the Plan
     ----------------

       Unless sooner terminated by the Board pursuant to Section 10, the Plan
shall terminate on April 11, 2007, and no Options may be granted after such
date.  The termination of the Plan shall not affect the validity of any Option
outstanding on the date of termination.


15.  Indemnification of Committee
     ----------------------------

       In addition to such other rights of indemnification as they may have as
Directors or as members of the Committee, the members of the Committee shall be
indemnified by the Company against the reasonable expenses, including attorneys'
fees, actually and reasonably incurred in connection with the defense of any
action, suit or proceeding, or in connection with any appeal therein, to which
they or any of them may be a party by reason of any action taken or failure to
act under or in connection with the Plan or any Option granted hereunder, and
against all amounts reasonably paid by them in settlement thereof or paid by
them in satisfaction of a judgment in any such action, suit or proceeding, if
such members acted in good faith and in a manner which they believed to be in,
and not opposed to, the best interests of the Company.

16.  General Provisions
     ------------------

       16.1.  The establishment of the Plan shall not confer upon any Eligible
Individual any legal or equitable right against the Company, any Affiliate or
the Committee, except as expressly provided in the Plan.

       16.2.  The Plan does not constitute inducement or consideration for the
employment or service of any Eligible Individual, nor is it a contract between
the Company or any Affiliate and any Eligible Individual. Participation in the
Plan shall not give an Eligible Individual any right to be retained in the
service of the Company or any Affiliate.

       16.3.  Neither the adoption of this Plan nor its submission to the
stockholders, shall be taken to impose any limitations on the powers of the
Company or its Affiliates to issue, grant, or assume options, warrants, rights,
or restricted stock, otherwise than under this Plan, or to adopt other stock
option or restricted stock plans or to impose any requirement of stockholder
approval upon the same.

       16.4.  The interests of any Eligible Individual under the Plan are not

       16.5.  The Plan shall be governed, construed and administered in

appropriate to reflect any restrictions on transfer. All certificates for Shares
issued pursuant to the Plan shall be subject to such stock transfer orders and
other restrictions as the Committee may deem advisable under the rules,
regulations and other requirements of the Securities and Exchange Commission,
any stock exchange or interdealer quotation system upon which the Common Stock
is then listed or quoted, and any applicable federal or state securities laws.

<PAGE>
 
                                     -10-

place a legend or legends on any such certificates to make appropriate reference
to such restrictions. The certificates for Shares acquired pursuant to an Option
may also include any legend which the Committee deems appropriate to reflect
restrictions contained in this Plan or in the applicable Agreement or to comply
with the Delaware General Corporation Law.

       16.7.  The Company shall not be required to issue any certificate or
certificates for Shares upon the exercise of Options, or record any person as a
holder of record of such Shares, without obtaining, to the complete satisfaction
of the Committee, the approval of all regulatory bodies deemed necessary by the
Committee, and without complying to the Committee's complete satisfaction, with
all rules and regulations, under federal, state or local law deemed applicable
by the Committee.

       Re:  Management Services
            -------------------


Gentlemen:

       This letter will confirm the agreement between TC Management L.L.C., a
Delaware limited liability company ("Thayer"), and Software AG Americas, Inc., a
Virginia corporation (the "Company"), pursuant to which Thayer will render to
the Company certain management and consulting services in connection with the
operation and conduct of the Company's business. Thayer shall commence providing
these services as of the date of this letter agreement (this "Agreement").
Thayer and the Company shall agree on the specific type and extent of services
to be provided pursuant to this Agreement.

       As consideration for the management and consulting services to be
provided to it by Thayer, the Company shall pay Thayer a quarterly fee of
$75,000 payable on the first business day of each calendar quarter, with the
first such payment to be made on the date hereof. Such fee shall be prorated for
any partial calendar quarter during which Thayer performs services hereunder.

       Thayer shall also be entitled to receive (or be reimbursed for) its
reasonable out-of-pocket expenses incurred in connection with its services
performed hereunder, upon submission of appropriate receipts and documentation
in support thereof.

       The doing of any act or the failure to do any act by Thayer or any of its
officers, directors, employees, partners, members or affiliates, or any person
who
<PAGE>
 
Software AG Americas, Inc.
Page 2



controls any of the foregoing, the effect of which may or does cause or result
in loss or damage to the Company or its affiliates, shall not subject Thayer, or
any of such persons or entities, to any liability to the Company, its affiliates
or any of their respective officers, directors, shareholders, employees or
affiliates, or to any other person whatsoever, except to the extent such loss or
damage is found in a final, non-appealable judgment by a court of competent
jurisdiction to have resulted from the willful misconduct of Thayer.

       In addition to its agreements and obligations under this Agreement, the
Company agrees to indemnify and hold harmless Thayer and its affiliates
(including its and their respective officers, directors, stockholders, partners,
members, employees, affiliates and agents) (each indemnitee is referred to
herein as an "Indemnified Person") from and against any and all claims,
liabilities, losses and damages (or actions in respect thereof), in any way
related to or arising out of the performance by such Indemnified Person of
services under this Agreement, and to reimburse each Indemnified Person for
reasonable legal and other expenses incurred by it in connection with or
relating to investigating, preparing to defend, or defending any actions, claims
or other proceedings (including any investigation or inquiry) arising in any
manner out of or in connection with such Indemnified Person's performance or
non-performance under this Agreement (whether or not such Indemnified Person is
a named party in such proceedings); provided, however, that the Company shall
                                    --------- -------                        
not be responsible under this paragraph for any claims, liabilities, losses,
damages or expenses to the extent that they are finally judicially determined to
result from actions taken by such Indemnified Person that constitute willful
misconduct.

       Thayer shall perform the services described herein until Thayer delivers
a written letter of resignation to the Company, which Thayer may do in its sole
discretion, at any time, and for any reason or no reason.

       This Agreement shall be binding upon and inure to the benefit of the
parties hereto, their legal representatives, successors and assigns. The
validity, interpretation, construction and performance of this Agreement shall
be governed by the laws of the

ACCEPTED AND AGREED TO:

    Executive Officer

<PAGE>
                                                                   EXHIBIT 10.11
 
                       DEFERRED COMPENSATION AGREEMENT 
                       -------------------------------

     THIS DEFERRED COMPENSATION AGREEMENT ("Agreement") is made and entered 
into as of the 1st day of July, 1995 (the "Effective Date"), by and between 
Software AG Americas, Inc., a Virginia corporation (the "Company"), and
Daniel Gillis, ("Executive").

     WITNESSETH:

     WHEREAS, Executive is currently employed by the Company in the capacity of
President & Chief Executive Officer, and has experience and knowledge of
considerable value to the Company; and

     WHEREAS, the Company wishes to offer an inducement to Executive to remain
in its employ by providing him with a supplemental compensation arrangement for
services which he has rendered or will render; and

     WHEREAS, Executive desires to continue in the employ of the Company in
order to earn certain deferred compensation benefits contingent on the
satisfaction of the provisions and conditions set forth herein; and

     WHEREAS, the Company agrees to make such contingent deferred compensation
benefits available to Executive; and

     WHEREAS, the Company and Executive desire to record in this Agreement the
terms and conditions for the earning and payment of such contingent deferred
compensation benefits.

     NOW, THEREFORE, in consideration of the foregoing premises, and of other
good and valuable consideration, the receipt and sufficiency of which are hereby
acknowledged, the Company and Executive hereby agree as follows:

     1. Scope of this Agreement. The Company hereby continues to employ
        -------- --------------                                        
Executive in the capacity of President & Chief Executive Officer, and Executive
hereby agrees to such continued employment. The parties acknowledge that this
Agreement does not generally include terms and conditions of the employment of
Executive by the Company but is intended only to address Executive's right to
certain deferred compensation benefits, as specified herein. The Company's
obligation to pay to Executive deferred compensation hereunder is independent
of, and unrelated to, any employment agreement or any other agreement, contract
or understandings which may exist between the Company and Executive, and any
amounts payable to Executive hereunder shall be in addition to, and not in
substitution for, any salary, bonus, other compensation, benefits or other
amounts otherwise paid or provided by the Company to Executive.
<PAGE>
 
     2. Deferred Compensation Account. The Company shall establish on its books
        -----------------------------                                          
a separate deferred compensation account (the "Account") which shall reflect the
amount of the Company's contingent liability to pay deferred compensation to
Executive in accordance with the terms of this Agreement. Amounts shall be
periodically credited to the Account as follows:

     (a) The balance of the Account shall initially be zero (0).

     (b) Effective as of July 31, 1995 the Company shall credit the Account 
with the amount of Forty-One Thousand Eight Hundred Thirty-Eight Dollars
($41,838.00). Effective as of March 31, 1996 and on each March 31 occurring
thereafter during Executive's term of active employment with the Company, the
Company shall credit the Account with an additional Forty-One Thousand Eight
Hundred Thirty-Eight Dollars ($41,838.00.00). In the event that Executive's
employment with the Company is terminated as of a date other than April 1 due to
death, incurrence of Permanent Disability (as defined in Section 3(b)) or
retirement on or after attaining age sixty (60), the Account will be credited as
of the date of termination of employment by an amount determined by multiplying
Forty-One Thousand Eight Hundred Thirty-Eight ($41,838.00). by a fraction, the
numerator of which is the number of days elapsed between the most recent March 3
1 and the date of termination of employment (or, if earlier, the date on which
Executive attains age sixty (60)) and the denominator of which is 365. If
Executives employment with the Company is terminated for any other reason as of
a date other than April 1, no additional credit will be made to the Account. In
addition, if Executive performs services for the Company subsequent to the
attainment of age sixty (60), a final credit will be made to Executive's Account
under this Paragraph (b), computed under the methodology described above as if
Executive had terminated employment on his sixtieth (60th) birthday. No
subsequent adjustments will be made to Executive's Account under this Paragraph
(b) with respect to any continued employment beyond Executive's sixtieth (60th)
birthday.

     (c) Effective as of September 30, 1995 (adjusted by 50% for the half 
year of 1995 only) and on each September 30 occurring thereafter during
Executive's term of active employment with the Company, the Company shall credit
the Account with an amount equal to Executive's Adjusted Estimated Bonus. The
Adjusted Estimated Bonus as of each September 30 shall be equal to the product
of (i) fifty percent (50%) of the bonus which the Company estimates will be paid
to Executive with respect to the then-current calendar year, computed by the
Company after considering all relevant facts and circumstances including
specified management goals, multiplied by (ii) a factor of .53. In the event
that Executive's employment with the Company is terminated as of a date other
than October 1, due to death, incurrence of Permanent Disability (as defined in
Section 3(b)) or retirement on or after attaining age sixty (60), the Account
shall be credited as of the date of termination of employment by an amount equal
to the Adjusted Estimated Bonus, as defined above, multiplied by a fraction, the
numerator of which is the number of days elapsed between the most recent
September 30 and the date of termination of employment (or, if earlier, the date
on which Executive attains age 60) and the denominator of which is 365. If
Executive's employment with the Company is terminated for any other reason as of
a date other than October 1, no additional credit will be made to the Account.
In addition, if Executive performs services for the Company subsequent to the
attainment of age sixty (60), a final credit will be made to Executive's Account
under this Paragraph (c), computed
<PAGE>
 
under the methodology described above as if Executive had terminated employment
on his sixtieth (60) birthday. No subsequent adjustments will be made to
Executive's Account under this Paragraph (c) with respect to any continued
employment beyond Executive's sixtieth (60th) birthday.

     (d) Effective as of December 31, 1995, and on each December 31 (adjusted by
50% for the half year of 1995 only), occurring thereafter during the Executive's
term of active employment with the Company, the Company shall credit the Account
with an amount equal to the difference between (i) .53 times the bonus actually
paid to the Executive in respect of the then-current calendar year and (ii) the
amount of the Adjusted Estimated Bonus credited to the Account as of the
immediately preceding September 30 pursuant to the provisions of Paragraph (c)
above. In the event that Executive's employment with the Company is terminated
as of a date other than January 1 due to death, incurrence of Permanent
Disability (as defined in Section 3(b)) or retirement on or after attaining age
sixty (60), the Account will be credited as of the date of termination of
employment by an amount equal to the product of (i) the difference between .53
times Executive's actual bonus paid in respect of the then-current year less the
Adjusted Estimated Bonus credited to the Executive's Account as of the
immediately preceding September 30 pursuant to the provisions of Paragraph (c),
above, multiplied by (ii) a fraction, the numerator of which is the number of
days elapsed between the most recent December 31 and the date of termination of
employment (or, if earlier, the date on which Executive attains age sixty (60))
and the denominator of which is 365. If the Executive's employment is terminated
for any other reason as of a date other than January 1, no additional credit
will be made to the Account. In addition, if Executive performs services for the
Company subsequent to the attainment of age sixty (60), a final credit will be
made to Executive's Account under this Paragraph (d), computed under the
methodology described above as if Executive had terminated employment on his
sixtieth (60th) birthday. No subsequent adjustments will be made to Executive's
Account under this Paragraph (d) with respect to any continued employment beyond
Executive's sixtieth (60th) birthday.

     (e) The Account balance shall be credited as of September 30 and March 31
of each year during which the Account has a positive balance by an interest
factor equal to three percent 3% of the then-existing Account balance. As such,
the rate of return to be applied pursuant to this Paragraph (e) is six percent
(6%) per year, compounded semi-annually.

     3. Entitlement to Deferred Compensation Benefits.
        --------------------------------------------- 

     (a) In the event that Executive terminates employment for any reason 
other than Permanent Disability, death, termination for "cause", as defined
below, or a voluntary quit, Executive shall have the right, commencing on or
about the date of termination of employment, to receive Deferred Compensation
Benefits, as defined in Section 5, below. It is intended and expected that
Executive give at least sixty (60) days notice prior to the date upon which such
termination becomes effective. Executive's entitlement to receipt of benefits
pursuant to this Agreement shall be conditioned upon Executive's compliance with
all terms and provisions of this Agreement.
<PAGE>
 
     (b) If Executive shall become Permanently Disabled, he shall become
entitled, as of the date on which the Company determines that Executive is
Permanently Disabled, to receive Deferred Compensation Benefits in accordance
with Section 5 hereof. For purposes of this Agreement, the term "Permanently
Disabled" means unable, by reason of any physical or mental illness, injury or
incapacity of permanent or indefinite duration, to perform substantially full-
time services to the Company in the capacity and at the level theretofore
employed, except that Executive shall not be deemed to be Permanently Disabled
unless and until such illness, injury or incapacity has continued unabated for
at least six (6) consecutive months. Executive agrees, as a condition of his
receipt of benefits hereunder, to undergo such physical examinations and tests
as any physician selected by the Company may reasonably request to ascertain
whether he is Permanently Disabled.

     4. Vesting. Executive's rights to receive deferred compensation hereunder
        -------                                                               
shall be automatically forfeited except to the extent that he has become vested
in a designated percentage of the Account balance on or before the date of his
retirement or termination of employment in accordance with the following rules.
In the event that Executive's employment is terminated for "cause", as defined
below, or in the event Executive voluntarily quits his employment, Executive
will forfeit entitlement to any and all benefits hereunder. Subject to the
provisions of Section 10, below, the vesting schedule is as follows and is based
upon total continuous employment performed by the Executive from his initial
date of hire.

        A.  Termination due to the Permanent Disability of Executive - Vesting
            100%

        B.  Termination for any reason other than Permanent Disability, death,
            termination for "cause" or a voluntary quit, Vesting will be based
            on the number of full years of continuous employment from
            Executive's initial date of hire as follows:

<TABLE>
        <S>                           <C>
        Less than 1 Year                0% Vested

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

For purposes of this Agreement, "cause" means: 1) Misconduct or conduct by
Executive which is illegal, dishonest, or involves moral turpitude; 2) Conduct
which jeopardizes the Company's right or ability to operate its business; 3) The
breach or violation of any other signed agreements, i.e. Confidentiality
Agreements, etc.; or 4) The destruction of Company property or business.

     5. Payment of Deferred Compensation Benefits. Provided that the vesting
        -----------------------------------------                           
requirements specified in Section 4 above are (or become) satisfied in whole or
in part as of the date of Executive's termination of employment, the Executive

<PAGE>
 
Entitlement Date, Executive shall have the option (1) to direct the Company to
pay to him his Deferred Compensation Benefits as a lump-sum payment effective as
of the Entitlement Date; (2) to direct the Company to purchase and assign an
annuity to him, effective as of the Entitlement Date or (3) to direct the
Company to make specified payments to him in installments over a fifteen (15)
year period commencing on the Entitlement Date. This election as to the form of
Deferred Compensation Benefits shall be made by Executive in a written notice to
the Company signed by Executive ("Election Notice") no less than ninety (90)
days prior to the Entitlement Date. If Executive fails to make an election at
least ninety (90) days prior to the Entitlement Date, the Company shall pay the
Deferred Compensation Benefits in the form of a lump-sum distribution.

        The forms in which Deferred Compensation Benefits may be paid are
described in greater detail as follows:

        (a) If Executive elects to receive a lump-sum payment or if Executive
otherwise fails to file an Election Notice on a timely basis, the Company shall
pay to Executive, in immediately-available funds, no later than thirty (30) days
after Entitlement Date, an amount equal to the total Account Balance, determined
as of the Entitlement Date, plus interest thereon through the Entitlement Date,
at the rate set forth in Section 2 hereof ("Final Account Balance").

        (b) If Executive elects in a timely manner to have the Company
purchase an annuity contract and to transfer such annuity contract to Executive,
the Company shall, within thirty (30) days after the date of the Election
Notice, assign and transfer to Executive a fully-paid annuity policy pursuant to
which an insurance company or other financial institution will make annuity
payments directly to Executive on the same dates as specified in 
subparagraph (c) below.

        (c) If Executive elects in a timely manner to have the Company pay
Deferred Compensation directly to Executive in annual installments, the Company
shall compute the amount of each annual installment based on amortization, over
a fifteen (15) year period, of the Final Account Balance, with interest thereon
at six percent (6%) per year, compounded annually, with the first annual
installment payment to be paid within thirty (30) days of the Entitlement Date.

     6. Death of Executive.
        ------------------- 

        (a) If Executive should die while still in the employ of the Company,
the Company shall pay to the "Beneficiary" in lieu of any other payments
hereunder, a death benefit equal to the amount in the Executive's deferred
compensation account at the time of death ("Death Benefit"). The Death Benefit
shall be paid to the Beneficiary, in immediately-available funds, on the first
day of the second month commencing after the date of death of Executive. For
purposes of this Agreement, the "Beneficiary" of the Executive is the person or
persons whose name or names and address or addresses, are set forth on Exhibit A
attached hereto and in effect on the date of Executive's death. Executive
retains the right to change his Beneficiary at any time by providing the Company
with his written, signed notice advising the Company of the name or names and
address or addresses of the person or persons who shall be the Beneficiary
<PAGE>
 
after the date of such notice. Upon receipt of any such notice, the Company
shall cause Exhibit A attached hereto to be changed to reflect the name or names
and address or addresses of the new Beneficiary. In the event that Executive
fails to designate a beneficiary or in the event the designated beneficiary
fails to survive Executive, Executive's Beneficiary shall be deemed to be his
estate.

        (b) If Executive shall die after becoming entitled to receive Deferred
Compensation Benefits pursuant to Section 5 hereof but before all of the
Deferred Compensation Benefits have been paid to him, his Beneficiary shall not
receive any Death Benefit under Section 6(a), above, but shall become entitled
to receive all Deferred Compensation Benefits that were not paid to Executive
prior to his death.

     7.  No Employment Obligation. This Agreement does not, in any manner,
         ------------------------                                         
commit or obligate the Company to continue to employ Executive, nor does it
commit to obligate Executive to continue in the employ of the Company.
Accordingly, the Company shall have the right, at any time, to terminate its
employment of the Executive for any reason, subject to the provisions of any
employment agreement or other contract between the Company and Executive.

     8.  Unfunded Obligation. The rights of Executive and his Beneficiary
         -------------------                                             
to receive Deferred Compensation Benefits or a Death Benefit hereunder shall be
solely those of an unsecured creditor of the Company. Neither Executive nor his
Beneficiary shall have any right with respect to any insurance policy, annuity
contract or any other asset which may be acquired or held by the Company in
connection with the contingent liabilities assumed by the Company hereunder. Any
such insurance policy, annuity contract or other asset shall not be deemed to be
held under any trust for the benefit of Executive or his beneficiaries or to be
held in any way as collateral security for the fulfillment of the obligations of
the Company under this Agreement, but shall be, and remain, a general,
unpledged, unrestricted asset of the Company, which the Company may modify or
cancel at any time.

     9.  Nonassignability. Except to the extent that Executive may designate
         ----------------                                         
his Beneficiary pursuant to Section 6 hereof to receive payments hereunder after
the date of his death, neither the Beneficiary nor Executive shall have the
right to commute, sell, assign, pledge, hypothecate or otherwise transfer or
encumber the right to receive any payments hereunder, which payments and the
right thereto are expressly declared to be nonassignable and nontransferable.

     10.  Sale, Merger or Consolidation. In the event the Company receives
          -----------------------------                                   
an offer to sell substantially all of its operating assets to another entity or
in the event of a proposed merger, consolidation or other business transfer, the
Company shall diligently pursue an attempt to cause the succeeding or continuing
corporation or other organization to expressly assume all of the obligations and
liabilities of the Company under this Agreement. In the event that the Company
is not able to cause such an assumption of obligations under this Agreement,
this Agreement shall be terminated.
<PAGE>
 
          Upon termination, the Executive will be entitled to receive a lump-sum
distribution of the portion of his Account in which he has then attained vested
status under the schedule set forth in Section 4B, based upon his years of
continuous employment earned through the effective date of such merger,
consolidation or acquisition. Such payment shall be made within thirty (30) days
of the consummation of such merger, consolidation or acquisition.

     11.  Miscellaneous.
          ------------- 

     (a)  This Agreement shall be governed by, and interpreted in accordance
with, the laws of the Commonwealth of Virginia, without giving effect to the
principles of conflicts of laws.

include the plural and vice-versa, and words of any gender shall be deemed to

Company shall include not only employment of Executive by Software AG Americas,

     (f)  This Agreement is binding upon, and inures to the benefit of, the
parties hereto and their heirs, executors, personal and legal representatives,
successors and permitted assigns.

either (i) a meaningful Company-wide reduction in compensation and/or benefits,

alteration or revocation) in which Executive is then vested under the schedule
set

forth in Section 4.B. In addition, in the event of the adoption of any
modification, amendment, alteration or revocation which would otherwise reduce
or eliminate the amount of future additions to Executive's Account, Executive's
rights upon termination of employment to the balance of the Account in existence
on the date of the adoption of such modification, amendment, alteration or
revocation shall be based upon the vesting schedule set forth in Section 4.B
computed by reference to Executive's full period of employment through the date
of such termination of employment (including employment subsequent to the date
of the modification, amendment, alteration or revocation of this Agreement).

          IN WITNESS WHEREOF, the Company, by its duly-authorized officers, has

signed and sealed this Agreement, all as of the day and year first set forth
above.

                        DEFERRED COMPENSATION AGREEMENT
                        -------------------------------
                                        

     THIS DEFERRED COMPENSATION AGREEMENT ("Agreement") is made and entered into
as of the 1St day of January, 1993 (the "Effective Date"), by and between
Software AG Americas, Inc., a Virginia corporation (the "Company"), and James H.
Daly, ("Executive").

     WITNESSETH:

     WHEREAS, Executive is currently employed by the Company in the capacity of
Vice President, General Counsel and Vice President, International Operations,
and has experience and knowledge of considerable value to the Company; and

     WHEREAS, the Company wishes to offer an inducement to Executive to remain
in its employ by providing him with a supplemental compensation arrangement for
services which he has rendered or will render; and

     WHEREAS, Executive desires to continue in the employ of the Company in
order to earn certain deferred compensation benefits contingent on the
satisfaction of the provisions and conditions set forth herein; and

     WHEREAS, the Company agrees to make such contingent deferred compensation
benefits available to Executive; and

     WHEREAS, the Company and Executive desire to record in this Agreement the
terms and conditions for the earning and payment of such contingent deferred
compensation benefits.

     NOW, THEREFORE, in consideration of the foregoing premises, and of other
good and valuable consideration, the receipt and sufficiency of which are hereby
acknowledged, the Company and Executive hereby agree as follows:

     1.  Scope of this Agreement. The Company hereby continues to employ
         -----------------------                                        
Executive in the capacity of Vice President, General Counsel and Vice President,
International Operations, and Executive hereby agrees to such continued
employment. The parties acknowledge that this Agreement does not generally
include terms and conditions of the employment of Executive by the Company but
is intended only to address Executive's right to certain deferred compensation
benefits, as specified herein.  The Company's obligation to pay to Executive
deferred compensation hereunder is independent of, and unrelated to, any
employment agreement or any other agreement, contract or understandings which
may exist between the Company and Executive, and any amounts payable to
Executive hereunder shall be in addition to, and not in substitution for, any
salary, bonus, other compensation, benefits or other amounts otherwise paid or
provided by the Company to Executive.
<PAGE>
 
     2.    Deferred Compensation Account. The Company shall establish on its
           -----------------------------                                    
books a separate deferred compensation account (the "Account") which shall
reflect the amount of the Company's contingent liability to pay deferred
compensation to Executive in accordance with the terms of this Agreement.
Amounts shall be periodically credited to the Account as follows:

     (a)   The balance of the Account shall initially be zero (0).

     (b)   Effective as of March 31, 1993 the Company shall credit the Account
with the amount of Twenty Four Thousand Dollars ($24,000.00). Effective as of
March 31, 1992 and on each March 31 occurring thereafter during Executive's term
of active employment with the Company, the Company shall credit the Account with
an additional Twenty Four Thousand Dollars ($24,000.00).  In the event that
Executive's employment with the Company is terminated as of a date other than
April 1 due to death, incurrence of Permanent Disability (as defined in Section
3(b)) or retirement on or after attaining age sixty (60), the Account will be
credited as of the date of termination of employment by an amount determined by
multiplying Twenty Four Thousand Dollars ($24,000.00) by a fraction, the
numerator of which is the number of days elapsed between the most recent 
March 31 and the date of termination of employment (or, if earlier, the date on
which Executive attains age sixty (60)) and the denominator of which is 365. If
Executive's employment with the Company is terminated for any other reason as of
a date other than April 1, no additional credit will be made to the Account. In
addition, if Executive performs services for the Company subsequent to the
attainment of age sixty (60), a final credit will be made to Executive's Account
under this Paragraph (b), computed under the methodology described above as if
Executive had terminated employment on his sixtieth (60th) birthday. No
subsequent adjustments will be made to Executive's Account under this Paragraph
(b) with respect to any continued employment beyond Executive's sixtieth (60th)
birthday.

     (c)   Effective as of September 30, 1993 and on each September 30 occurring
thereafter during Executive's term of active employment with the Company, the
Company shall credit the Account with an amount equal to Executive's Adjusted
Estimated Bonus.  The Adjusted Estimated Bonus as of each September 30 shall be
equal to the product of (i) fifty percent (50%) of the bonus which the Company
estimates will be paid to Executive with respect to the then-current calendar
year, computed by the Company after considering all relevant facts and
circumstances including specified management goals, multiplied by (ii) a factor
of 1.20. In the event that Executive's employment with the Company is terminated
as of a date other than October 1, due to death, incurrence of Permanent
Disability (as defined in Section 3(b)) or retirement on or after attaining age
sixty (60), the Account shall be credited as of the date of termination of
employment by an amount equal to the Adjusted Estimated Bonus, as defined above,
multiplied by a fraction, the numerator of which is the number of days elapsed
between the most recent September 30 and the date of termination of employment
(or, if earlier, the date on which Executive attains age 60) and the denominator
of which is 365.  If Executive's employment with the Company is terminated for
any other reason as of a date other than October 1, no additional credit will be
made to the Account. In addition, if Executive performs services for the Company
subsequent to the attainment of age sixty (60), a final credit will be

 
<PAGE>
 
made to Executive's Account under this Paragraph (c), computed under the
methodology described above as if Executive had terminated employment on his
sixtieth (60) birthday. No subsequent adjustments will be made to Executive's
Account under this Paragraph (c) with respect to any continued employment beyond
Executive's sixtieth (60th) birthday.

     (d)   Effective as of December 31, 1993, and on each December 31,
occurring thereafter during the Executive's term of active employment with the
Company, the Company shall credit the Account with an amount equal to the
difference between (i) 1.20 times the bonus actually paid to the Executive in
respect of the then-current calendar year and (ii) the amount of the Adjusted
Estimated Bonus credited to the Account as of the immediately preceding
September 30 pursuant to the provisions of Paragraph (c) above. In the event
that Executive's employment with the Company is terminated as of a date other
than January 1 due to death, incurrence of Permanent Disability (as defined in
Section 3(b)) or retirement on or after attaining age sixty (60), the Account
will be credited as of the date of termination of employment by an amount equal
to the product of (i) the difference between 1.20 times Executive's actual bonus
paid in respect of the then-current year less the Adjusted Estimated Bonus
credited to the Executive's Account as of the immediately preceding September 30
pursuant to the provisions of Paragraph (c), above, multiplied by (ii) a
fraction, the numerator of which is the number of days elapsed between the most
recent December 31 and the date of termination of employment (or, if earlier,
the date on which Executive attains age sixty (60)) and the denominator of which
is 365. If the Executive's employment is terminated for any other reason as of a
date other than January 1, no additional credit will be made to the Account. In
addition, if Executive performs services for the Company subsequent to the
attainment of age sixty (60), a final credit will be made to Executive's Account
under this Paragraph (d), computed under the methodology described above as if
Executive had terminated employment on his sixtieth (60th) birthday. No
subsequent adjustments will be made to Executive's Account under this Paragraph
(d) with respect to any continued employment beyond Executive's sixtieth (60th)
birthday.

     (e)   The Account balance shall be credited as of September 30 and 
March 31 of each year during which the Account has a positive balance by an
interest factor equal to three percent 3% of the then-existing Account balance.
As such, the rate of return to be applied pursuant to this Paragraph (e) is six
percent (6%) per year, compounded semi-annually.

     3.    Entitlement to Deferred Compensation Benefits.
           --------------------------------------------- 

     (a)   In the event that Executive terminates employment for any reason
other than Permanent Disability, death, termination for "cause", as defined
below, or a voluntary quit, Executive shall have the right, commencing on or
about the date of termination of employment, to receive Deferred Compensation
Benefits, as defined in Section 5, below. It is intended and expected that
Executive give at least sixty (60) days notice prior to the date upon which such
termination becomes effective. Executive's entitlement to receipt of benefits
pursuant to this Agreement shall be conditioned upon Executive's compliance with
all terms and provisions of this Agreement.

<PAGE>
 
      (b)  If Executive shall become Permanently Disabled, he shall become
entitled, as of the date on which the Company determines that Executive is
Permanently Disabled, to receive Deferred Compensation Benefits in accordance
with Section 5 hereof. For purposes of this Agreement, the term "Permanently
Disabled" means unable, by reason of any physical or mental illness, injury or
incapacity of permanent or indefinite duration, to perform substantially full-
time services to the Company in the capacity and at the level theretofore
employed, except that Executive shall not be deemed to be Permanently Disabled
unless and until such illness, injury or incapacity has continued unabated for
at least six (6) consecutive months. Executive agrees, as a condition of his
receipt of benefits hereunder, to undergo such physical examinations and tests
as any physician selected by the Company may reasonably request to ascertain
whether he is Permanently Disabled.

     4.    Vesting. Executive's rights to receive deferred compensation
           -------                                                     
hereunder shall be automatically forfeited except to the extent that he has
become vested in a designated percentage of the Account balance on or before the
date of his retirement or termination of employment in accordance with the
following rules. In the event that Executive's employment is terminated for
"cause", as defined below, or in the event Executive voluntarily quits his
employment, Executive will forfeit entitlement to any and all benefits
hereunder. Subject to the provisions of Section 10, below, the vesting schedule
is as follows and is based upon total continuous employment performed by the
Executive from his initial date of hire.

        A.  Termination due to the Permanent Disability of Executive - Vesting
            100%

        B.  Termination for any reason other than Permanent Disability, death,
            termination for "cause" or a voluntary quit. Vesting will be based
            on the number of full years of continuous employment from
            Executive's initial date of hire as follows:
<TABLE> 
            <S>                                                    <C>

            ------------------------------------------------------------------
            4 Years                                                 80% Vested
            ------------------------------------------------------------------

            ------------------------------------------------------------------
</TABLE> 
For purposes of this Agreement, "cause" means: 1) Misconduct or conduct by
Executive which is illegal, dishonest, or involves moral turpitude; 2) Conduct
which jeopardizes the Company's right or ability to operate its business; 3) The
breach or violation of any other signed agreements, i.e. Confidentiality
Agreements, etc.; or 4) The destruction of Company property or business.

     5.    Payment of Deferred Compensation Benefits.  Provided that the vesting
           -----------------------------------------                            
requirements specified in Section 4 above are (or become) satisfied in whole or
in part as of the date of Executive's termination of employment, the Executive
shall, as of the termination of his employment (the "Entitlement Date"), become
entitled to receive from the Company payments of deferred compensation as set
forth below ("Deferred Compensation Benefits"). Prior to the


<PAGE>
 
Entitlement Date, Executive shall have the option (1) to direct the Company to
pay to him his Deferred Compensation Benefits as a lump-sum payment effective as
of the Entitlement Date; (2) to direct the Company to purchase and assign an
annuity to him, effective as of the Entitlement Date or (3) to direct the
Company to make specified payments to him in installments over a fifteen (15)
year period commencing on the Entitlement Date. This election as to the form of
Deferred Compensation Benefits shall be made by Executive in a written notice to
the Company signed by Executive ("Election Notice") no less than ninety (90)
days prior to the Entitlement Date. If Executive fails to make an election at
least ninety (90) days prior to the Entitlement Date, the Company shall pay the
Deferred Compensation Benefits in the form of a lump-sum distribution.

          The forms in which Deferred Compensation Benefits may be paid are
described in greater detail as follows:

          (a) If Executive elects to receive a lump-sum payment or if Executive
otherwise fails to file an Election Notice on a timely basis, the Company shall
pay to Executive, in immediately-available funds, no later than thirty (30) days
after Entitlement Date, an amount equal to the total Account Balance, determined
as of the Entitlement Date, plus interest thereon through the Entitlement Date,
at the rate set forth in Section 2 hereof ("Final Account Balance").

          (b) If Executive elects in a timely manner to have the Company
purchase an annuity contract and to transfer such annuity contract to Executive,
the Company shall, within thirty (30) days after the date of the Election
Notice, assign and transfer to Executive a fully-paid annuity policy pursuant to
which an insurance company or other financial institution will make annuity
payments directly to Executive on the same dates as specified in subparagraph
(c) below.

          (c) If Executive elects in a timely manner to have the Company pay
Deferred Compensation directly to Executive in annual installments, the Company
shall compute the amount of each annual installment based on amortization, over
a fifteen (15) year period, of the Final Account Balance, with interest thereon
at six percent (6%) per year, compounded annually, with the first annual
installment payment to be paid within thirty (30) days of the Entitlement Date.

     6.   Death of Executive.
          ------------------ 

          (a) If Executive should die while still in the employ of the Company,
the Company shall pay to the "Beneficiary" in lieu of any other payments
hereunder, a death benefit equal to the amount in the Executive's deferred
compensation account at the time of death ("Death Benefit"). The Death Benefit
shall be paid to the Beneficiary, in immediately-available funds, on the first
day of the second month commencing after the date of death of Executive. For
purposes of this Agreement, the "Beneficiary" of the Executive is the person or
persons whose name or names and address or addresses, are set forth on Exhibit A
attached hereto and in effect on the date of Executive's death. Executive
retains the right to change his Beneficiary at any time by providing the Company
with his written, signed notice advising the Company of the name or names and
address or addresses of the person or persons who shall be the Beneficiary

<PAGE>
 
after the date of such notice. Upon receipt of any such notice, the Company
shall cause Exhibit A attached hereto to be changed to reflect the name or names
and address or addresses of the new Beneficiary. In the event that Executive
fails to designate a beneficiary or in the event the designated beneficiary
fails to survive Executive, Executive's Beneficiary shall be deemed to be his
estate.

          (b) If Executive shall die after becoming entitled to receive Deferred
Compensation Benefits pursuant to Section 5 hereof but before all of the
Deferred Compensation Benefits have been paid to him, his Beneficiary shall not
receive any Death Benefit under Section 6(a), above, but shall become entitled
to receive all Deferred Compensation Benefits that were not paid to Executive
prior to his death.

          7.  No Employment Obligation. This Agreement does not, in any manner,
              ------------------------                                         
commit or obligate the Company to continue to employ Executive, nor does it
commit to obligate Executive to continue in the employ of the Company.
Accordingly, the Company shall have the right, at any time, to terminate its
employment of the Executive for any reason, subject to the provisions of any
employment agreement or other contract between the Company and Executive.

          8.  Unfunded Obligation.  The rights of Executive and his Beneficiary
              -------------------                                              
to receive Deferred Compensation Benefits or a Death Benefit hereunder shall be
solely those of an unsecured creditor of the Company. Neither Executive nor his
Beneficiary shall have any right with respect to any insurance policy, annuity
contract or any other asset which may be acquired or held by the Company in
connection with the contingent liabilities assumed by the Company hereunder. Any
such insurance policy, annuity contract or other asset shall not be deemed to be
held under any trust for the benefit of Executive or his beneficiaries or to be
held in any way as collateral security for the fulfillment of the obligations of
the Company under this Agreement, but shall be, and remain, a general,
unpledged, unrestricted asset of the Company, which the Company may modify or
cancel at any time.

          9.  Nonassignability. Except to the extent that Executive may
              ----------------                                         
designate his Beneficiary pursuant to Section 6 hereof to receive payments
hereunder after the date of his death, neither the Beneficiary nor Executive
shall have the right to commute, sell, assign, pledge, hypothecate or otherwise
transfer or encumber the right to receive any payments hereunder, which payments
and the right thereto are expressly declared to be nonassignable and
nontransferable.

          10. Sale, Merger or Consolidation. In the event the Company receives
              -----------------------------                                   
an offer to sell substantially all of its operating assets to another entity or
in the event of a proposed merger, consolidation or other business transfer, the
Company shall diligently pursue an attempt to cause the succeeding or continuing
corporation or other organization to expressly assume all of the obligations and
liabilities of the Company under this Agreement. In the event that the Company
is not able to cause such an assumption of obligations under this Agreement,
this Agreement shall be terminated.

<PAGE>
 
               Upon termination, the Executive will be entitled to receive a
lump-sum distribution of the portion of his Account in which he has then
attained vested status under the schedule set forth in Section 4B, based upon
his years of continuous employment earned through the effective date of such
merger, consolidation or acquisition. Such payment shall be made within thirty
(30) days of the consummation of such merger, consolidation or acquisition.

          11.  Miscellaneous.
               ------------- 

          (a)  This Agreement shall be governed by, and interpreted in
accordance with, the laws of the Commonwealth of Virginia, without giving effect
to the principles of conflicts of laws.

          (b)  Where text requires, words in the singular shall be deemed to
include the plural and vice-versa, and words of any gender shall be deemed to
include all genders.

          (c)  Any headings preceding the text of the several sections of this
Agreement are inserted solely for convenience of reference and shall not
constitute a part of this Agreement nor shall they affect its meaning,
construction or effect.

          (d)  For purposes of this Agreement, employment of Executive by the
Company shall include not only employment of Executive by Software AG Americas,
Inc., but also employment of Executive by any subsidiary, parent or other
affiliate of Software AG Americas, Inc.

          (e)  All notices pertaining to this Agreement shall be either hand-
delivered or sent by certified mail, return receipt requested, with first class
postage prepaid as follows: (i) if to the Company, to Software AG Americas,
Inc., 11190 Sunrise Valley Drive, Reston, Virginia 22091, Attention: Chief
Financial Officer; or (ii) to such other address as either of the parties shall
designate by written notice to the other from time to time pursuant to this
Section. Time periods contained in any notice shall commence on the date of hand
delivery or mailing, as the case may be. Any notice which is required to be
given within a stated period of time shall be considered timely if either hand
delivered or postmarked on or before midnight of the last day of such period.

          (f)  This Agreement is binding upon, and inures to the benefit of, the
parties hereto and their heirs, executors, personal and legal representatives,
successors and permitted assigns.

          (g)  This Agreement may be modified, amended, altered or revoked only
by mutual consent of the parties or by the Company within ninety (90) days of
either (i) a meaningful Company-wide reduction in compensation and/or benefits,
or (ii) following a meaningful reduction in force. However, no such
modification, amendment, alteration or revocation shall adversely affect
Executive's entitlements hereunder to the component of Executive's Account (as
determined on the date of the adoption of such modification, amendment,
alteration or revocation) in which Executive is then vested under the schedule
set

<PAGE>
 
forth in Section 4.B. In addition, in the event of the adoption of any
modification, amendment, alteration or revocation which would otherwise reduce
or eliminate the amount of future additions to Executive's Account, Executive's
rights upon termination of employment to the balance of the Account in existence
on the date of the adoption of such modification, amendment, alteration or
revocation shall be based upon the vesting schedule set forth in Section 4.B
computed by reference to Executive's full period of employment through the date
of such termination of employment (including employment subsequent to the date
of the modification, amendment, alteration or revocation of this Agreement).

            IN WITNESS WHEREOF, the Company, by its duly-authorized officers,
has caused this Agreement to be executed and sealed, and Executive has by his
hand signed and sealed this Agreement, all as of the day and year first set
forth above.

                        DEFERRED COMPENSATION AGREEMENT
                        -------------------------------

     THIS DEFERRED COMPENSATION AGREEMENT ("Agreement") is made and entered into
as of the 1st day of January, 1991 (the "Effective Date"), by and between
Software AG Americas, Inc., a Virginia corporation (the "Company"), and Harry K.
McCreery, ("Executive").

     WITNESSETH:

     WHEREAS, Executive is currently employed by the Company in the capacity of
Chief Financial Officer, and has experience and knowledge of considerable value
to the Company; and

     WHEREAS, the Company wishes to offer an inducement to Executive to remain
in its employ by providing him with a supplemental compensation arrangement for
services which he has rendered or will render; and

     WHEREAS, Executive desires to continue in the employ of the Company in
order to earn certain deferred compensation benefits contingent on the
satisfaction of the provisions and conditions set forth herein; and

     WHEREAS, the Company agrees to make such contingent deferred compensation
benefits available to Executive; and

     WHEREAS, the Company and Executive desire to record in this Agreement the
terms and conditions for the earning and payment of such contingent deferred
compensation benefits.

     NOW, THEREFORE, in consideration of the foregoing premises, and of other
good and valuable consideration, the receipt and sufficiency of which are hereby
acknowledged, the Company and Executive hereby agree as follows:

     1. Scope of this Agreement. The Company hereby continues to employ
        -----------------------                                        
Executive in the capacity of Chief Financial Officer, and Executive hereby
agrees to such continued employment. The parties acknowledge that this Agreement
does not generally include terms and conditions of the employment of Executive
by the Company but is intended only to address Executive's right to certain
deferred compensation benefits, as specified herein. The Company's obligation to
pay to Executive deferred compensation hereunder is independent of, and
unrelated to, any employment agreement or any other agreement, contract or
understandings which may exist between the Company and Executive, and any
amounts payable to Executive hereunder shall be in addition to, and not in
substitution for, any salary, bonus, other compensation, benefits or other
amounts otherwise paid or provided by the Company to Executive.
<PAGE>
 
     2.  Deferred Compensation Account. The Company shall establish on its books
         -----------------------------                                          
a separate deferred compensation account (the "Account") which shall reflect the
amount of the Company's contingent liability to pay deferred compensation to
Executive in accordance with the terms of this Agreement. Amounts shall be
periodically credited to the Account as follows:

     (a) The balance of the Account shall initially be zero (0).

     (b) Effective as of March 31, 1991 the Company shall credit the Account
with the amount of Forty-Six Thousand Dollars ($46,000.00). Effective as of
March 31, 1992 and on each March 31 occurring thereafter during Executive's term
of active employment with the Company, the Company shall credit the Account with
an additional Forty-Six Thousand Dollars ($46,000.00). In the event that
Executive's employment with the Company is terminated as of a date other than
April 1 due to death, incurrence of Permanent Disability (as defined in Section
3(b)) or retirement on or after attaining age sixty (60), the Account will be
credited as of the date of termination of employment by an amount determined by
multiplying Forty-Six Thousand Dollars ($46,000.00) by a fraction, the numerator
of which is the number of days elapsed between the most recent March 31 and the
date of termination of employment (or, if earlier, the date on which Executive
attains age sixty (60)) and the denominator of which is 365. If Executive's
employment with the Company is terminated for any other reason as of a date
other than April 1, no additional credit will be made to the Account. In
addition, if Executive performs services for the Company subsequent to the
attainment of age sixty (60), a final credit will be made to Executive's Account
under this Paragraph (b), computed under the methodology described above as if
Executive had terminated employment on his sixtieth (60th) birthday. No
subsequent adjustments will be made to Executive's Account under this Paragraph
(b) with respect to any continued employment beyond Executive's sixtieth (60th)
birthday.

     (c) Effective as of September 30, 1991 and on each September 30 occurring
thereafter during Executive's term of active employment with the Company, the
Company shall credit the Account with an amount equal to Executive's Adjusted
Estimated Bonus. The Adjusted Estimated Bonus as of each September 30 shall be
equal to the product of (i) fifty percent (50%) of the bonus which the Company
estimates will be paid to Executive with respect to the then-current calendar
year, computed by the Company after considering all relevant facts and
circumstances including specified management goals, multiplied by (ii) a factor
of 1.00. In the event that Executive's employment with the Company is terminated
as of a date other than October 1, due to death, incurrence of Permanent
Disability (as defined in Section 3(b)) or retirement on or after attaining age
sixty (60), the Account shall be credited as of the date of termination of
employment by an amount equal to the Adjusted Estimated Bonus, as defined above,
multiplied by a fraction, the numerator of which is the number of days elapsed
between the most recent September 30 and the date of termination of employment
(or, if earlier, the date on which Executive attains age 60) and the denominator
of which is 365. If Executive's employment with the Company is terminated for
any other reason as of a date other than October 1, no additional credit will be
made to the Account. In addition, if Executive performs services for the Company
subsequent to the attainment of age sixty (60), a final credit will be
<PAGE>
 
made to Executive's Account under this Paragraph (c), computed under the
methodology described above as if Executive had terminated employment on his
sixtieth (60) birthday. No subsequent adjustments will be made to Executive's
Account under this Paragraph (c) with respect to any continued employment beyond
Executive's sixtieth (60th) birthday.

     (d) Effective as of December 31, 1991, and on each December 31, occurring
thereafter during the Executive's term of active employment with the Company,
the Company shall credit the Account with an amount equal to the difference
between (i) 1.00 times the bonus actually paid to the Executive in respect of
the then-current calendar year and (ii) the amount of the Adjusted Estimated
Bonus credited to the Account as of the immediately preceding September 30
pursuant to the provisions of Paragraph (c) above. In the event that Executive's
employment with the Company is terminated as of a date other than January 1 due
to death, incurrence of Permanent Disability (as defined in Section 3(b)) or
retirement on or after attaining age sixty (60), the Account will be credited as
of the date of termination of employment by an amount equal to the product of
(i) the difference between 1.00 times Executive's actual bonus paid in respect
of the then-current year less the Adjusted Estimated Bonus credited to the
Executive's Account as of the immediately preceding September 30 pursuant to the
provisions of Paragraph (c), above, multiplied by (ii) a fraction, the numerator
of which is the number of days elapsed between the most recent December 31 and
the date of termination of employment (or, if earlier, the date on which
Executive attains age sixty (60)) and the denominator of which is 365. If the
Executive's employment is terminated for any other reason as of a date other
than January 1, no additional credit will be made to the Account. In addition,
if Executive performs services for the Company subsequent to the attainment of
age sixty (60), a final credit will be made to Executive's Account under this
Paragraph (d), computed under the methodology described above as if Executive
had terminated employment on his sixtieth (60th) birthday. No subsequent
adjustments will be made to Executive's Account under this Paragraph (d) with
respect to any continued employment beyond Executive's sixtieth (60th) birthday.

     (e) The Account balance shall be credited as of September 30 and March 31
of each year during which the Account has a positive balance by an interest
factor equal to three percent 3% of the then-existing Account balance. As such,
the rate of return to be applied pursuant to this Paragraph (e) is six percent
(6%) per year, compounded semi-annually.

     3.  Entitlement to Deferred Compensation Benefits.
         --------------------------------------------- 

     (a) In the event that Executive terminates employment for any reason other
than Permanent Disability, death, termination for "cause", as defined below, or
a voluntary quit, Executive shall have the right, commencing on or about the
date of termination of employment, to receive Deferred Compensation Benefits, as
defined in Section 5, below. It is intended and expected that Executive give at
least sixty (60) days notice prior to the date upon which such termination
becomes effective. Executive's entitlement to receipt of benefits pursuant to
this Agreement shall be conditioned upon Executive's compliance with all terms
and provisions of this Agreement.
<PAGE>
 
     (b) If Executive shall become Permanently Disabled, he shall become
entitled, as of the date on which the Company determines that Executive is
Permanently Disabled, to receive Deferred Compensation Benefits in accordance
with Section 5 hereof. For purposes of this Agreement, the term "Permanently
Disabled" means unable, by reason of any physical or mental illness, injury or
incapacity of permanent or indefinite duration, to perform substantially full-
time services to the Company in the capacity and at the level theretofore
employed, except that Executive shall not be deemed to be Permanently Disabled
unless and until such illness, injury or incapacity has continued unabated for
at least six (6) consecutive months. Executive agrees, as a condition of his
receipt of benefits hereunder, to undergo such physical examinations and tests
as any physician selected by the Company may reasonably request to ascertain
whether he is Permanently Disabled.

     4.  Vesting. Executive's rights to receive deferred compensation hereunder
         -------                                                               
shall be automatically forfeited except to the extent that he has become vested
in a designated percentage of the Account balance on or before the date of his
retirement or termination of employment in accordance with the following rules.
In the event that Executive's employment is terminated for "cause", as defined
below, or in the event Executive voluntarily quits his employment, Executive
will forfeit entitlement to any and all benefits hereunder. Subject to the
provisions of Section 10, below, the vesting schedule is as follows and is based
upon total continuous employment performed by the Executive from his initial
date of hire.

         A.  Termination due to the Permanent Disability of Executive - Vesting
             100%

         B.  Termination for any reason other than Permanent Disability, death,
             termination for "cause" or a voluntary quit, Vesting will be based
             on the number of full years of continuous employment from
             Executive's initial date of hire as follows:

<TABLE> 
         <S>                                        <C>

         ------------------------------------------------------
         2 Years                                     40% Vested
         ------------------------------------------------------
         3 Years                                     60% Vested
         ------------------------------------------------------
         4 Years                                     80% Vested
         ------------------------------------------------------
         5 or More Years                            100% Vested
         ------------------------------------------------------
</TABLE> 

For purposes of this Agreement, "cause" means: 1) Misconduct or conduct by
Executive which is illegal, dishonest, or involves moral turpitude; 2) Conduct
which jeopardizes the Company's right or ability to operate its business; 3) The
breach or violation of any other signed agreements, i.e. Confidentiality
Agreements, etc.; or 4) The destruction of Company property or business.

     5.  Payment of Deferred Compensation Benefits. Provided that the vesting
         -----------------------------------------                           
requirements specified in Section 4 above are (or become) satisfied in whole or
in part as of the date of Executive's termination of employment, the Executive
shall, as of the termination of his employment (the "Entitlement Date"), become
entitled to receive from the Company payments of deferred compensation as set
forth below ("Deferred Compensation Benefits"). Prior to the
<PAGE>
 
Entitlement Date, Executive shall have the option (1) to direct the Company to
pay to him his Deferred Compensation Benefits as a lump-sum payment effective as
of the Entitlement Date; (2) to direct the Company to purchase and assign an
annuity to him, effective as of the Entitlement Date or (3) to direct the
Company to make specified payments to him in installments over a fifteen (15)
year period commencing on the Entitlement Date. This election as to the form of
Deferred Compensation Benefits shall be made by Executive in a written notice to
the Company signed by Executive ("Election Notice") no less than ninety (90)
days prior to the Entitlement Date. If Executive fails to make an election at
least ninety (90) days prior to the Entitlement Date, the Company shall pay the
Deferred Compensation Benefits in the form of a lump-sum distribution.

         The forms in which Deferred Compensation Benefits may be paid are
described in greater detail as follows:

         (a) If Executive elects to receive a lump-sum payment or if Executive
otherwise fails to file an Election Notice on a timely basis, the Company shall
pay to Executive, in immediately-available funds, no later than thirty (30) days
after Entitlement Date, an amount equal to the total Account Balance, determined
as of the Entitlement Date, plus interest thereon through the Entitlement Date,
at the rate set forth in Section 2 hereof ("Final Account Balance").

         (b) If Executive elects in a timely manner to have the Company
purchase an annuity contract and to transfer such annuity contract to Executive,
the Company shall, within thirty (30) days after the date of the Election
Notice, assign and transfer to Executive a fully-paid annuity policy pursuant to
which an insurance company or other financial institution will make annuity
payments directly to Executive on the same dates as specified in subparagraph
(c) below.

         (c) If Executive elects in a timely manner to have the Company pay
Deferred Compensation directly to Executive in annual installments, the Company
shall compute the amount of each annual installment based on amortization, over
a fifteen (15) year period, of the Final Account Balance, with interest thereon
at six percent (6%) per year, compounded annually, with the first annual
installment payment to be paid within thirty (30) days of the Entitlement Date.

     6.  Death of Executive.
         ------------------ 

         (a) If Executive should die while still in the employ of the Company,
the Company shall pay to the "Beneficiary" in lieu of any other payments
hereunder, a death benefit equal to the amount in the Executive's deferred
compensation account at the time of death ("Death Benefit"). The Death Benefit
shall be paid to the Beneficiary, in immediately-available funds, on the first
day of the second month commencing after the date of death of Executive. For
purposes of this Agreement, the "Beneficiary" of the Executive is the person or
persons whose name or names and address or addresses, are set forth on Exhibit A
attached hereto and in effect on the date of Executive's death. Executive
retains the right to change his Beneficiary at any time by providing the Company
with his written, signed notice advising the Company of the name or names and
address or addresses of the person or persons who shall be the Beneficiary
<PAGE>
 
after the date of such notice. Upon receipt of any such notice, the Company
shall cause Exhibit A attached hereto to be changed to reflect the name or names
and address or addresses of the new Beneficiary. In the event that Executive
fails to designate a beneficiary or in the event the designated beneficiary
fails to survive Executive, Executive's Beneficiary shall be deemed to be his
estate.

         (b) If Executive shall die after becoming entitled to receive Deferred
Compensation Benefits pursuant to Section 5 hereof but before all of the
Deferred Compensation Benefits have been paid to him, his Beneficiary shall not
receive any Death Benefit under Section 6(a), above, but shall become entitled
to receive all Deferred Compensation Benefits that were not paid to Executive
prior to his death.

         7.  No Employment Obligation. This Agreement does not, in any manner,
             ------------------------                                         
commit or obligate the Company to continue to employ Executive, nor does it
commit to obligate Executive to continue in the employ of the Company.
Accordingly, the Company shall have the right, at any time, to terminate its
employment of the Executive for any reason, subject to the provisions of any
employment agreement or other contract between the Company and Executive.

         8.  Unfunded Obligation. The rights of Executive and his Beneficiary
             -------------------                                             
to receive Deferred Compensation Benefits or a Death Benefit hereunder shall be
solely those of an unsecured creditor of the Company. Neither Executive nor his
Beneficiary shall have any right with respect to any insurance policy, annuity
contract or any other asset which may be acquired or held by the Company in
connection with the contingent liabilities assumed by the Company hereunder. Any
such insurance policy, annuity contract or other asset shall not be deemed to be
held under any trust for the benefit of Executive or his beneficiaries or to be
held in any way as collateral security for the fulfillment of the obligations of
the Company under this Agreement, but shall be, and remain, a general,
unpledged, unrestricted asset of the Company, which the Company may modify or
cancel at any time.

         9.  Nonassignability. Except to the extent that Executive may
             ----------------                                         
designate his Beneficiary pursuant to Section 6 hereof to receive payments
hereunder after the date of his death, neither the Beneficiary nor Executive
shall have the right to commute, sell, assign, pledge, hypothecate or otherwise
transfer or encumber the right to receive any payments hereunder, which payments
and the right thereto are expressly declared to be nonassignable and
nontransferable.

         10. Sale Merger or Consolidation. In the event the Company receives
             -----------------------------                                   
an offer to sell substantially all of its operating assets to another entity or
in the event of a proposed merger, consolidation or other business transfer, the
Company shall diligently pursue an attempt to cause the succeeding or continuing
corporation or other organization to expressly assume all of the obligations and
liabilities of the Company under this Agreement. In the event that the Company
is not able to cause such an assumption of obligations under this Agreement,
this Agreement shall be terminated.

<PAGE>
 
             Upon termination, the Executive will be entitled to receive a lump-
sum distribution of the portion of his Account in which he has then attained
vested status under the schedule set forth in Section 4B, based upon his years
of continuous employment earned through the effective date of such merger,
consolidation or acquisition. Such payment shall be made within thirty (30) days
of the consummation of such merger, consolidation or acquisition.

         11. Miscellaneous.
             ------------- 

         (a) This Agreement shall be governed by, and interpreted in accordance
with, the laws of the Commonwealth of Virginia, without giving effect to the
principles of conflicts of laws.

         (b) Where text requires, words in the singular shall be deemed to
include the plural and vice-versa, and words of any gender shall be deemed to
include all genders.

         (c) Any headings preceding the text of the several sections of this
Agreement are inserted solely for convenience of reference and shall not
constitute a part of this Agreement nor shall they affect its meaning,
construction or effect.

         (d) For purposes of this Agreement, employment of Executive by the
Company shall include not only employment of Executive by Software AG Americas,
Inc., but also employment of Executive by any subsidiary, parent or other
affiliate of Software AG Americas, Inc.

         (e) All notices pertaining to this Agreement shall be either hand-
delivered or sent by certified mail, return receipt requested, with first class
postage prepaid as follows: (i) if to the Company, to Software AG Americas,
Inc., 11190 Sunrise Valley Drive, Reston, Virginia 22091, Attention: Chief
Financial Officer; or (ii) to such other address as either of the parties shall
designate by written notice to the other from time to time pursuant to this
Section. Time periods contained in any notice shall commence on the date of hand
delivery or mailing, as the case may be. Any notice which is required to be
given within a stated period of time shall be considered timely if either hand
delivered or postmarked on or before midnight of the last day of such period.

         (f) This Agreement is binding upon, and inures to the benefit of, the
parties hereto and their heirs, executors, personal and legal representatives,
successors and permitted assigns.

         (g) This Agreement may be modified, amended, altered or revoked only
by mutual consent of the parties or by the Company within ninety (90) days of
either (i) a meaningful Company-wide reduction in compensation and/or benefits,
or (ii) following a meaningful reduction in force. However, no such
modification, amendment, alteration or revocation shall adversely affect
Executive's entitlements hereunder to the component of Executive's Account (as
determined on the date of the adoption of such modification, amendment,
alteration or revocation) in which Executive is then vested under the schedule
set
<PAGE>
 
forth in Section 4.B. In addition, in the event of the adoption of any
modification, amendment, alteration or revocation which would otherwise reduce
or eliminate the amount of future additions to Executive's Account, Executive's
rights upon termination of employment to the balance of the Account in existence
on the date of the adoption of such modification, amendment, alteration or
revocation shall be based upon the vesting schedule set forth in Section 4.B
computed by reference to Executive's full period of employment through the date
of such termination of employment (including employment subsequent to the date
of the modification, amendment, alteration or revocation of this Agreement).

         IN WITNESS WHEREOF, the Company, by its duly-authorized officers, has
caused this Agreement to be executed and sealed, and Executive has by his hand
signed and sealed this Agreement, all as of the day and year first set forth
above.

                       ADMINISTRATIVE SERVICES AGREEMENT
                       ---------------------------------

       This Administrative Services Agreement ("Agreement") is made as of March
31, 1997 (the "Effective Date") by and between Software AG ("SAG"), a German
corporation, with its principal place of business in Darmstadt, Germany, and
Software AG Americas, Inc. ("SAGA"), a Virginia corporation, with its principal
place of business in Reston, Virginia, USA.

       WHEREAS, prior to the Effective Date, SAGA has been an indirect wholly-
owned subsidiary of SAG; and

       WHEREAS, prior to the Effective Date, pursuant to a Products and Research
& Development Operations Transfer Agreement between SAG and Software AG of North
America, Inc. (currently named SAGA) dated December 5, 1993 (the "Prior
Agreement"), certain individuals on the payroll of SAGA have performed computer
software development and other services for SAG under the management of SAG, and
SAG has reimbursed SAGA for all of its costs associated with such employees and
such development and other services; and

       WHEREAS, the parties desire to clarify certain aspects of such
relationship;

       NOW THEREFORE, in consideration of the mutual promises contained herein
and intending to be legally bound hereby, the parties agree as follows:


1.  Termination of Prior Agreement
    ------------------------------

       1.1. All ongoing rights and obligations of the parties under the Prior
Agreement are hereby terminated and superseded by this Agreement; provided that
any rights or obligations of the parties with respect to performance that has
been rendered, or that was to have been rendered, under the Prior Agreement
prior to the Effective Date shall be governed by the terms of the Prior
Agreement.


2.  Administrative Services to Be Provided
    --------------------------------------

       2.1. SAGA shall provide the following administrative services to SAG:

             2.1.1.  On behalf of SAG, SAGA shall maintain on SAGA's payroll and
       provide SAGA's standard employee benefits to the individuals identified
       in Exhibit A and any additional individuals subsequently agreed upon by
       the parties and whose names are added to Exhibit A
<PAGE>
 
                                     - 2 -

(collectively, the "Designated Employees"), until the earlier of the date on
which any such individual assumes a position within SAGA that does not involve
performing computer software development or other services for SAG under the
management of SAG or the date on which the employment of any such individual by
SAGA is terminated, either at the request of SAG or, if deemed necessary by
SAGA, at SAGA's initiative, after which date such an individual no longer shall
be considered a Designated Employee and such an individual's name shall be
deleted from Exhibit A.

    2.1.2.  SAGA shall provide human resources services for Designated
Employees, including services relating to the recruitment of Designated
Employees, consistent with the human resources services provided for other SAGA
employees.

    2.1.3.  SAGA shall provide Designated Employees working space in a SAGA
facility consistent with the working space provided to other SAGA employees. If
SAG wishes to make any material change in the working space provided as of the
Effective Date or subsequently agreed to by the parties, SAG shall notify SAGA
of such proposed change, and the parties shall discuss, and may agree to, the
change. SAGA shall use reasonable efforts to accommodate within 90 days
reasonable working space changes proposed by SAG, to the extent consistent with
the availability of space, lease provisions, applicable laws and regulations,
safety and security concerns, and other applicable constraints. All costs
incurred by SAGA as the result of any change in working space requirements
initiated by SAG shall be paid by SAG. Except as provided in Article 5, SAGA
shall not be responsible for the safekeeping of property of SAG or of Designated
Employees stored at SAGA's facility.

    2.1.4.  SAGA shall provide Designated Employees access to applicable SAGA
facilities and use of computer systems and networks, telephones and office
equipment to an extent consistent with policies and practices adopted by SAGA
from time to time.

    2.1.5.  SAGA specifically shall not be responsible for the direct or
indirect management of Designated Employees or for the performance of Designated
Employees. SAGA makes no representations or warranties with respect to, and
shall have no liability for, the qualifications, training or performance of
Designated Employees. The relationship of SAGA to SAG under this Agreement is
<PAGE>
 
                                     - 3 -

       solely that of an administrative services provider within the capacity
       and normal policies and practices of SAGA.

       2.2. SAG shall be solely responsible for (i) selection of Designated
Employees and determination of the compensation of Designated Employees,
provided that such compensation shall be consistent with policies and practices
adopted by SAGA from time to time, (ii) day-to-day and long-term management of
the Designated Employees, and (iii) all actions of the Designated Employees. As
part of such responsibility, SAG diligently shall supervise the Designated
Employees. SAG shall comply with, and shall cause the Designated Employees to
comply with, (a) all safety, security, computer access and other policies and
practices applicable to SAGA employees and others working in SAGA's facility
that may be adopted by SAGA from time to time, and (b) all applicable laws and
regulations. To the extent that SAG fails to cause such compliance, SAGA may,
without limiting any remedies against SAG that SAGA may have at law or in
equity, take appropriate disciplinary action against Designated Employees,
including but not limited to termination of Designated Employees, in which case
SAG shall pay all costs incurred by SAGA as the result of the discipline. SAG
shall appoint one or more of the Designated Employees as a "SAG Supervisor,"
each of whom shall be identified as a "SAG Supervisor" in Exhibit A and who
shall be responsible for the management of the Designated Employees. SAG shall
cause a SAG Supervisor to be accessible to SAGA at reasonable times and without
unreasonable delay as the principal point of contact between the parties for
matters relating to this Agreement. Each SAG Supervisor shall have the
authority, on behalf of SAG, to take any action or enter into any agreement
related to the Designated Employees or the administrative services to be
provided under this Agreement. Such authority shall include decisions, on behalf
of SAG, relating to the hiring, compensation and termination of Designated
Employees.

       2.3. Should SAG no longer require the services of any Designated
Employee, SAG shall so notify SAGA in writing. Upon receipt of such notice, SAGA
may in its discretion offer the Designated Employee another position within
SAGA. If SAGA elects not to offer such a position, or if the Designated Employee
rejects such an offer, SAGA may terminate such Designated Employee in accordance
with policies and practices adopted by SAGA from time to time. SAG shall comply
with such policies and practices. If a Designated Employee's employment with
SAGA is terminated, then SAG shall pay all costs of such termination, including
but not limited to severance payments and payments for accrued leave.

3.  Payment
    -------

       3.1.  SAG shall reimburse SAGA for all costs incurred by SAGA as a result
of SAGA's selection, hiring, failing to hire, employment or termination of
Designated Employees or otherwise related to the performance of SAGA's
obligations under this Agreement, except for the cost of the CMOS machine
currently installed in SAGA's Reston Data Center (which is the subject of
Section 3.2). The basis of this reimbursement is described in Exhibit B.

       3.2.  During the years 1997, 1998 and 1999, SAG shall pay SAGA $500,000
per year, on a monthly basis, for the CMOS machine currently installed in SAGA's
Reston Data Center. SAG shall be obligated to make such payments through 1999
notwithstanding any expiration or termination of this Agreement prior to 
January 1, 2000.

       3.3.  Within 15 days after the end of each calendar month, SAGA will
submit invoices to SAG setting forth the amounts payable under this Agreement
with respect to such month. SAG shall pay all such invoiced amounts within 30
days after the date of the invoice. Any late payment hereunder shall accrue
interest at a rate equal to the currency-related FIBOR rate available on the due
date of such payment, plus three percent. At any time, SAGA may offset any
amount owed by SAG to SAGA under this Agreement by making a corresponding
reduction in any amount owed by SAGA to SAG under any other agreement or
arrangement. SAGA shall promptly notify SAG of any such offset.

       3.4.  During the term of this Agreement and for one year thereafter, SAG
shall have the right, one time during each calendar year, at its expense and
upon reasonable notice, to examine or have examined by its authorized
representative, SAGA's relevant books and records relating to the immediately
preceding calendar year solely in order to verify the accuracy of any invoices
furnished hereunder.


4.  Proprietary Rights
    ------------------

       4.1.  Any computer software, data or other items furnished to Designated
Employees by SAGA, in which SAGA and not SAG owns the proprietary rights, shall
remain the sole property of SAGA, and to the extent such computer software, data
or other items are disclosed to SAG, SAG shall hold such computer software, data
or other items in confidence in accordance with Article 5. Subject to the
foregoing, SAG shall own all of the proprietary rights arising from the work of
the Designated Employees, and SAGA shall hold all computer software, data or
<PAGE>
 
                                     - 5 -

other items developed by Designated Employees in confidence in accordance with
Article 5.

       4.2. Any computer software developed by Designated Employees shall be a
"SAG Product" for purposes of the Cooperation Agreement between the parties
dated March 31, 1997.


5.  Confidentiality
    ---------------

       5.1.  For the purpose of this Article 5, the term "Confidential
Information" means any information used in or relating to the business of one
party or its affiliates (collectively, the "Disclosing Party"), including, but
not limited to, the Disclosing Party's product plans, technical materials and
financial and customer information, that the Disclosing Party maintains in
confidence, and all tangible embodiments of such information, that is received
by the other party or its affiliates (the "Receiving Party"), or to which the
Receiving Party has access, in any form; provided that "Confidential
Information" does not include any information that the Receiving Party can
demonstrate (i) is or becomes publicly known through no fault of the Receiving
Party; (ii) is developed independently by the Receiving Party; or (iii) is
rightfully obtained by the Receiving Party from a third party not obligated to
preserve its confidentiality who did not receive the material or information
directly or indirectly from the Disclosing Party.

       5.2.  A Receiving Party (i) shall not use the Disclosing Party's
Confidential Information for any purpose other than in accordance with this
Agreement and other agreements between the parties and (ii) shall not disclose
Confidential Information to any person or entity, other than any of its
employees, agents and independent contractors who have a need to know such
Confidential Information and who are subject to a nondisclosure obligation
comparable in scope to this Article 5.

       5.3.  Notwithstanding Section 5.2, a Receiving Party may disclose
Confidential Information to the extent required by a court or other governmental
authority, provided that (i) the Receiving Party gives the Disclosing Party
reasonable notice of the disclosure, (ii) the Receiving Party uses reasonable
efforts to resist disclosing the Confidential Information, and (iii) upon
request of the Disclosing Party, the Receiving Party cooperates with the
Disclosing Party to obtain a protective order regarding, or otherwise limit, the
disclosure.

       5.4.  The parties acknowledge that either party's breach of Section 5.2
would cause the other party irreparable injury for which it would not have an
adequate remedy at law. In the event of such a breach, the non-breaching party
shall be

<PAGE>
 
                                     - 6 -

entitled to injunctive relief in addition to any other remedies it may have at
law or in equity, without having to prove any actual damages sustained.


6.  Indemnity
    ---------

       6.1. Subject to Section 6.2, SAG shall defend, indemnify and hold
harmless SAGA, its affiliates, and their respective directors, officers, agents
and employees from and against all claims, liabilities, suits, losses, damages
and expenses, including costs and reasonable attorneys' fees ("Claims") relating
to or resulting from (i) SAG'S breach of this Agreement, (ii) the negligence of
SAG or of Designated Employees, (iii) allegations that SAGA has failed to
supervise Designated Employees, (iv) infringements of patents, copyrights or
other proprietary rights by Designated Employees, (v) failure of SAG or of
Designated Employees to comply with applicable laws and regulations, (vi) any
other actions or inactions of Designated Employees, and (vii) SAGA'S selection,
hiring, failing to hire, employment or termination of Designated Employees.

       6.2. The foregoing indemnity is subject to the following conditions:

             6.2.1.  An indemnified person or entity promptly shall notify SAG
       in writing of any Claim (provided that the failure of an indemnified
       person or entity to provide prompt notice shall not relieve SAG of its
       obligations under this Article 6, except to the extent that SAG is
       actually prejudiced by such failure); and

             6.2.2.  SAG shall have the right, if it so chooses, to control and
       direct, at its expense and through counsel of its choosing, the
       investigation and defense of any third party Claim, but may compromise or
       settle the same only with the consent of the indemnified person or
       entity, which consent shall not be unreasonably withheld. The indemnified
       person or entity shall cooperate fully with SAG in the defense of any
       such Claim.

       6.3. Upon receipt of a notice of a Claim for indemnification, SAG shall
promptly pay to the indemnified person or entity the amount of such Claim in
accordance with and subject to the provisions of this Article 6, provided,
however, that no such payment shall be due during any period in which SAG is
contesting in good faith either its obligation to make such indemnification or
the amount of the Claim that is payable.

7.  Term and Termination
    --------------------

       7.1.  The initial term of this Agreement shall commence on the Effective
Date and continue until December 31, 1998 unless this Agreement is terminated in
accordance with Section 7.2. Thereafter, this Agreement automatically shall be
extended for subsequent one-year renewal terms unless (i) either party gives the
other party written notice of non-renewal at least 90 days prior to the end of
the then-current initial or renewal term, or (ii) this Agreement is terminated
in accordance with Section 7.2.

       7.2.  If either party materially breaches this Agreement and fails to
remedy that breach within fifteen days after receiving written notice of that
breach from the other party, the non-breaching party may terminate this
Agreement immediately upon further written notice.

       7.3.  Upon any expiration or termination of this Agreement, SAGA may in
its discretion offer one or more Designated Employees other positions within
SAGA. If SAGA elects not to offer one or more Designated Employees such
positions, or if one or more Designated Employees reject such offers, SAGA may
terminate such Designated Employees in accordance with policies and practices

9.     Miscellaneous
       -------------

             9.1. This Agreement is confidential, and neither party shall
disclose it without the prior written consent of the other party to any third
party, other than its attorneys, consultants, accountants, auditors and others
to whom a party has a bona fide business reason for disclosing the Agreement;
provided that each party may disclose this Agreement as may be required by law
or to enforce the provisions hereof.

             9.2. The parties shall use the English language in exchanging all
documents and other information exchanged between them.

             9.3. The provisions of this Agreement are severable, and the
unenforceability of any provision of this Agreement shall not affect the
enforceability of the remainder of this Agreement. The parties acknowledge that
it is their intention that if any provision of this Agreement is determined by a
court to be invalid, illegal or unenforceable as drafted, that provision should
be construed in a manner designed to effectuate the purpose of that provision to
the greatest extent possible under applicable law.

             9.4. The rights and remedies provided in this Agreement are,
to the extent permitted by law, cumulative and not
<PAGE>
 
                                     - 9 -

exclusive of any other right or remedy now or hereafter available at law or in
equity. Neither asserting a right nor employing a remedy shall preclude the
concurrent assertion of any other right or employment of any other remedy, nor
shall the failure to assert, or the delay in asserting, any right or remedy
constitute a waiver of that right or remedy.

             9.5.  The rights of the parties under this Agreement are unique,
and the failure of a party to perform its obligations hereunder would
irreparably harm the other party. Accordingly, the parties shall, in addition to
such other remedies as may be available at law or in equity, have the right to
enforce their rights hereunder by actions for specific performance to the extent
permitted by law.

             9.6.  No party may assign any of its rights or delegate its
obligations hereunder without the written consent of the other party, except
that SAGA may make such an assignment and/or delegation to any affiliate of
SAGA. Any purported assignment or delegation in violation of this Section 9.6
shall be void. This Agreement shall be binding upon and inure to the benefit of
the parties and their respective successors, permitted assigns and legal
representatives.

             9.7.  This Agreement may be modified or amended only by written
agreement of the parties.

             9.8.  The validity, interpretation, construction and performance of
this Agreement shall be governed by the laws of the Commonwealth of Virginia
applicable to agreements made and entirely to be performed within such
jurisdiction. The party bringing any action under this Agreement shall only be
entitled to choose the federal or state courts in the Commonwealth of Virginia
as the venue for such action, and each party consents to the jurisdiction of the
court chosen in such manner for such action.

             9.9.  This Agreement may be executed in any number of counterparts,
and each such counterpart shall be deemed to be an original instrument, but all
such counterparts together shall constitute but one agreement.

             9.10. This Agreement constitutes the entire agreement between the
parties with respect to the subject matter hereof and supersedes all previous
agreements, written or oral, with respect to the subject matter hereof.

           at that time agree to an adjustment in the applicable reimbursement
           rate.

       2.  Demand Registrations.
           -------------------- 

           (a) Request for Registration. If a Majority-in-Interest submits a
               ------------------------                                       
written request (a "Demand Notice") to the Company subsequent to an IPO Event
that the Company register Registrable Shares under and in accordance with the
Securities Act (a "Demand Registration"), then the Company shall:

               (i)    within 5 business days after receipt of such Demand
Notice, give written notice of the proposed registration to all other Investors;
and

               (ii)   as soon as practicable, use reasonable diligent efforts to
effect such registration as may be so requested and as would permit or
facilitate the sale and distribution of all or such portion of such Registrable
Shares as are specified in such request,

                                     - 4 -
<PAGE>
 
together with all or such portion of the Registrable Shares of any Investors
joining in such request as are specified in written requests received by the
Company within 10 business days after the date the Company sends the written
notice referred to in clause (i) above.

       Notwithstanding the foregoing, however, the Company shall not be
obligated to take any action to effect any such registration under this Section
2 within six months immediately following the effective date of any registration
statement pertaining to securities of the Company in which the Investors were
given the right to register Registrable Shares pursuant to the registration
rights described in Section 3 hereof and the number of Registrable Shares
included in such registration was not reduced from the number of Registrable
Shares requested to be included pursuant to Section 3(b). Nor shall the Company
be obligated to complete more than five Demand Registrations or more than one
Demand Registration on Form S-1 (or any successor form).

       In addition, if the Company shall furnish to the Majority-in-Interest
under this Section 2 a certificate signed by the president of the Company
stating that in the good faith judgment of the board of directors of the
Company, it would be seriously detrimental to the

                                     - 5 -
<PAGE>
 
Company or its stockholders for a registration statement to be filed on or
before the date filing would be required in connection with any Demand
Registration and it is therefore essential to defer the filing of such
registration statement, the Company shall have the right to defer such filing
for a reasonable period not to exceed an additional ninety (90) days provided
that such right shall not be exercised more than once with respect to a request
for registration hereunder; and in any such event, the Majority-in-Interest will
be entitled to withdraw their request for registration hereunder. If any such
request is withdrawn as provided in the immediately preceding sentence, such
registration will not be considered a permitted Demand Registration hereunder,
and the Company will pay all Registration Expenses in connection with such
withdrawn request for registration.

           (b) Underwriting. In connection with any registration under this
               ------------                                                
Section 2, if so requested, the Company shall enter into an underwriting
agreement with one or more underwriters selected by the Majority-in-Interest
having terms and conditions customary for such agreements.

       3.  Company Registration.
           -------------------- 

           (a) Notice of Registration. If at any time or from time to time, the
               ----------------------                                          
Company shall determine to

                                     - 6 -
<PAGE>
 
register any of its Common Stock, whether or not for its own account, other than
a registration relating to employee benefit plans or a registration relating to
a Rule 145 transaction, the Company shall:

               (i)    provide to each Investor written notice thereof at least
10 business days prior to the filing of the registration statement by the
Company in connection with such registration; and

               (ii)   include in such registration, and in any underwriting
involved therein, all those Registrable Shares specified in a written request by
each Investor received by the Company within 5 business days after the Company
sends the written notice referred to above, subject to the provisions of Section
3(b) below.

           (b) Underwriting. The right of any Investor to registration pursuant
               ------------                                                    
to this Section 3 shall be conditioned upon the participation by such Investor
in the underwriting arrangements specified by the Company in connection with
such registration and the inclusion of the Registrable Shares of such Investor
in such underwriting to the extent provided herein. All Investors proposing to
distribute their Registrable Shares through such underwriting shall (together
with the Company) enter into an underwriting agreement in

                                     - 7 -
<PAGE>
 
customary form with the managing underwriter selected for such underwriting by
the Company and take all other actions, and deliver such opinions and
certifications, as may be reasonably requested by such managing underwriter.
Notwithstanding any other provision of this Section 3, if the managing
underwriter determines that marketing factors require a limitation of the number
of shares to be underwritten, the managing underwriter may limit the number of
Registrable Shares to be included in such registration. The Company shall so
advise all Investors distributing Registrable Shares through such underwriting,
and there shall be excluded from such registration and underwriting, to the
extent necessary to satisfy such limitation, first shares held by the Investors
and, thereafter, to the extent necessary, shares which the Company wishes to
register for its own account. As among the Investors as a group, the number of
Registrable Shares that may be included in the registration and underwriting
shall be allocated among them in proportion, as nearly as practicable, to the
respective amounts of Registrable Shares required to be included (determined
without regard to any requirement of a request to be included in such
registration) in such registration held by all Investors at the time of filing
the registration statement. To

                                     - 8 -
<PAGE>
 
facilitate the allocation of shares in accordance with the above provisions, the
Company may round the number of shares allocated to any Investor to the nearest
100 shares.

       (c) Right to Terminate Registration. The Company shall have the right to
           -------------------------------                                     
terminate or withdraw any registration initiated by it under this Section 3
prior to the effectiveness of such registration whether or not any Investor has
elected to include Registrable Shares in such registration.

       4.  Expense of Registration. All Registration Expenses incurred in
           -----------------------                                       
connection with the registration and other obligations of the Company pursuant
to Sections 2, 3 and 5 shall be borne by Company; provided, however, that
Company shall not be required to pay for expenses of any registration begun
pursuant to Section 2, the request for which has been subsequently withdrawn by
the Majority-in-Interest, in which case such expenses shall be borne by the
Majority-in-Interest pro rata in accordance with the number of Registrable
Shares initially sought to be registered, unless the Majority-in-Interest
withdraw their request for registration hereunder as a result of a deferral of
the filing of such registration statement at the request of

                                     - 9 -
<PAGE>
 
the Company, in which case, the Company will pay all Registration Expenses in
connection with such registration.

       5.  Registration Procedures. If and whenever the Company is required by
           -----------------------                                            
the provisions of this Agreement to effect the registration of Registrable
Shares, the Company shall:

           (a) promptly prepare and file with the Commission a registration
statement with respect to such Registrable Shares, and use its reasonable
diligent efforts to cause such registration statement to become effective as
promptly as practicable and remain effective thereafter as provided herein,
provided that prior to filing a registration statement or prospectus or any
amendments or supplements thereto, including documents incorporated by reference
after the initial filing of any registration statement, the Company will furnish
to each of the Investors whose Registrable Shares are covered by such
registration statement, their counsel and the underwriters copies of all such
documents proposed to be filed sufficiently in advance of filing to provide them
with a reasonable opportunity to review such documents and comment thereon;

           (b) prepare and file with the Commission such amendments (including
post-effective amendments)

                                    - 10 -
<PAGE>
 
and supplements to such registration statement and the prospectus used in
connection therewith as may be necessary to keep such registration statement
effective and current and to comply with the provisions of the Securities Act
with respect to the sale or other disposition of all Registrable Shares covered
by such registration statement, including such amendments (including post-
effective amendments) and supplements as may be necessary to reflect the
intended method of disposition by the prospective seller or sellers of such
Registrable Shares, but (except for a shelf registration) for no longer than 120
days subsequent to the effective date of such registration statement;

          (c) provide customary indemnity and contribution arrangements to any
qualified independent underwriter or qualified independent pricer as defined in
Schedule E of the Bylaws of the National Association of Securities Dealers, Inc.
(a "Qualified Independent Underwriter/Pricer"), if requested by such Qualified
Independent Underwriter/Pricer, on such reasonable terms as such Qualified
Independent Underwriter/Pricer customarily requires;

          (d) subject to receiving reasonable assurances of confidentiality, for
a reasonable period after the filing of such registration statement, and

                                    - 11 -
<PAGE>
 
throughout each period during which the Company is required to keep a
registration effective, make available for inspection by the selling holders of
Registrable Shares being offered, and any underwriters, and their respective
counsel, such financial and other information and books and records of the
Company, and cause the officers, directors, employees, counsel and independent
certified public accountants of the Company to respond to such inquiries as
shall be reasonably necessary, in the judgment of such counsel, to conduct a
reasonable investigation within the meaning of Section 11 of the Securities Act;

          (e) promptly notify the selling holders of Registrable Shares and any
underwriters and confirm such advice in writing, (i) when such registration
statement or the prospectus included therein or any prospectus amendment or
supplement or post-effective amendment has been filed, and, with respect to
such registration statement or any post-effective amendment, when the same has
become effective, (ii) of any comments by the Commission, by the National
Association of Securities Dealers Inc. ("NASD"), and by the Blue Sky or
securities commissioner or regulator of any state with respect thereto or any
request by any such entity for amendments or supplements to such registration
statement or

                                    - 12 -
<PAGE>
 
prospectus or for additional information, (iii) of the issuance by the
Commission of any stop order suspending the effectiveness of such registration
statement or the initiation or threatening of any proceedings for that purpose,
(iv) if at any time the representations and warranties of the Company cease to
be true and correct in all material respects, (v) of the receipt by the Company
of any notification with respect to the suspension of the qualification of the
Registrable Shares for sale in any jurisdiction or the initiation or threatening
of any proceeding for such purpose, or (vi) at any time when a prospectus is
required to be delivered under the Securities Act, that such registration
statement, prospectus, prospectus amendment or supplement or post-effective
amendment, or any document incorporated by reference in any of the foregoing,
contains an untrue statement of a material fact or omits to state any material
fact required to be stated therein or necessary to make the statements therein,
in light of the circumstances under which they are made, not misleading;

          (f) furnish to each selling holder of Registrable Shares being
offered, and any underwriters, prospectuses or amendments or supplements
thereto, in

                                    - 13 -
<PAGE>
 
such quantities as they may reasonably request and as soon as practicable, that
update previous prospectuses or amendments or supplements thereto;

          (g) in the case of a registration under Section 3 hereof, permit
selling holders of Registrable Shares to rely on any representations and
warranties made to any underwriter of the Company or any opinion of counsel or
"cold comfort" letter delivered to any such underwriter, and indemnify each such
holder to the same extent that it indemnities any such underwriter;

          (h) use reasonable diligent efforts to (i) register or qualify the
Registrable Shares to be included in a registration statement hereunder under
such other securities laws or blue sky laws of such jurisdictions within the
United States of America as any selling holder of such Registrable Shares or any
underwriter of the securities being sold shall reasonably request, (ii) keep
such registrations or qualifications in effect for so long as the registration
statement remains in effect and (ii) take any and all such actions as may be
reasonably necessary or advisable to enable such holder or underwriter to
consummate the disposition in such jurisdictions of such Registrable Shares
owned by such holder; provided, however, that the Company shall not be required
                      --------  -------                                        
for any such purpose to

                                    - 14 -

jurisdiction wherein it would not otherwise be required to qualify but for the
requirements of this Section 5(h), (y) subject itself to taxation in any such

jurisdiction;

          (i) cause all such Registrable Shares to be listed or accepted for
quotation on each securities exchange or automated quotation system on which the
Company's Common Stock then trades; and

          (j) otherwise use reasonable diligent efforts to comply with all
applicable provisions of the Securities Act, and rules and regulations of the
Commission, and make available to its security holders, as soon as reasonably
practicable, an earning statement covering a period of at least twelve months
which shall satisfy the provisions of Section 11(a) of the Securities Act and
Rule 158 thereunder.

     6.   Indemnification. In the event any of the Registrable Shares are
          ---------------
included in a registration statement under this Agreement:

          (a) the Company will indemnify each Investor who participates in such
registration, each of its officers and directors and partners and such
Investor's separate legal counsel and independent

                                    - 15 -
<PAGE>
 
accountants, and each person controlling such Investor within the meaning of
Section 15 of the Securities Act, and each underwriter, if any, and each person
who controls any underwriter within the meaning of Section 15 of the Securities
Act, against all expenses, claims, losses, damages or liabilities (or actions in
respect thereof), including any of the foregoing incurred in settlement of any
litigation, commenced or threatened, arising out of or based on any untrue
statement (or alleged untrue statement) of a material fact contained in any
registration statement, prospectus, offering circular or other document, or any
amendment or supplement thereto, incident to any such registration,
qualification or compliance, or based on any omission (or alleged omission) to
state therein a material fact required to be stated therein or necessary to make
the statements therein, in light of the circumstances in which they were made,
not misleading, or any violation by the Company of any rule or regulation
promulgated under the Securities Act applicable to the Company in connection
with any such registration, qualification or compliance, and the Company will
reimburse each such Investor, each of its officers and directors and partners
and such Investor's separate legal counsel and independent accountants and

                                    - 16 -
<PAGE>
 
each person controlling such Investor, each such underwriter and each person who
controls any such underwriter, for any legal and any other expenses reasonably
incurred in connection with investigating, preparing or defending any such
claim, loss, damage, liability or action, provided that the Company will not be
liable in any such case to the extent that any such claim, loss, damage,
liability or expense arises out of or is based on any untrue statement or
omission or alleged untrue statement or omission, made in reliance upon and in
conformity with written information furnished to the Company by an instrument
duly executed by such Investor or underwriter and stated to be specially for use
therein.

          (b) Each Investor will, if Registrable Shares held by such Investor
are included in the securities as to which such registration, qualification or
compliance is being effected, indemnify the Company, each of its directors and
officers and its legal counsel and independent accountants, each underwriter, if
any, of the Company's securities covered by such a registration statement, each
person who controls the Company or such underwriter within the meaning of
Section 15 of the Securities Act, and each other such Investor, each of its
officers and directors and each

                                    - 17 -
<PAGE>
 
person controlling such Investor within the meaning of Section 15 of the
Securities Act, against all claims, losses, damages and liabilities (or actions
in respect thereof) arising out of or based on any untrue statement (or alleged
untrue statement) of a material fact contained in any such registration
statement, prospectus, offering circular or other document, or any omission (or
alleged omission) to state therein a material fact required to be stated therein
or necessary to make the statement therein not misleading, and will reimburse
the Company, such Investors, such directors, officers, persons, underwriters or
control persons for any legal or any other expenses reasonably incurred in
connection with investigating or defending any such claim, loss, damage,
liability or action, in each case to the extent, but only to the extent, that
such untrue statement (or alleged untrue statement) or omission (or alleged
omission) is made in such registration statement, prospectus, offering circular
or other document in reliance upon and in conformity with written information
furnished to the Company by an instrument duly executed by such Investor and
stated to be specifically for use therein.

            (c) Each party entitled to indemnification under this Section 6 (the
"Indemnified Party") shall

                                    - 18 -
<PAGE>
 
give notice to the party required to provide indemnification (the "Indemnifying
Party") promptly after such Indemnified Party has actual knowledge of any claim
as to which indemnity may be sought provided that failure to give such prompt
notice shall not relieve the Indemnifying Party of its obligations hereunder
unless it is materially prejudiced thereby, and shall permit the Indemnifying
Party to assume the defense of any such claim or any litigation resulting
therefrom, provided that counsel for the Indemnifying Party, who shall conduct
the defense of such claim or litigation, shall be approved by the Indemnified
Party (whose approval shall not unreasonably be withheld). Such Indemnified
Party shall have the right to employ separate counsel in any such action and to
participate in the defense thereof, but the fees and expenses of such counsel
shall be that of such Indemnified Party unless (i) the Indemnifying Party has
agreed to pay such fees and expenses or (ii) the Indemnifying Party shall have
failed to assume the defense of such action or proceeding and employ counsel
reasonably satisfactory to such Indemnified Party in any such action or
proceeding or (iii) the named parties to any such action or proceeding
(including any impleaded parties) include both such Indemnified Party and the
Indemnifying Party

                                    - 19 -
<PAGE>
 
and such Indemnified Party shall have been advised by counsel that there may be
one or more legal defenses available to such Indemnified Party which are
different from or additional to those available to the Indemnifying Party (in
which case, if such Indemnified Party notifies the Indemnifying Party in writing
of an election to employ separate counsel at the expense of the Indemnifying
Party, the Indemnifying Party shall not have the right to assume the defense of
such action or proceeding on behalf of such Indemnified Party, it being
understood, however, that the Indemnifying Party then shall have the right to
employ separate counsel at its own expense and to participate in the defense
thereof, and shall not, in connection with any one such action or proceeding or
separate but substantially similar or related actions or proceedings in the same
jurisdiction arising out of the same general allegations or circumstances, be
liable for the reasonable fees and expenses of more than one separate firm of
attorneys at any time for all Indemnified Parties, which firm shall be
designated in writing by a majority of the Indemnified Parties who are eligible
to select such counsel). No Indemnifying Party, in the defense of any such claim
or litigation, shall, except with the consent of each Indemnified Party, consent
to entry of any

                                    - 20 -
<PAGE>
 
judgment or enter into any settlement which does not include as an unconditional
term thereof the giving by the claimant or plaintiff to such Indemnified Party
of a release from all liability in respect to such claim or litigation. No
Indemnified Party may consent to entry of any judgment or enter into any
settlement without the prior written consent of the Indemnifying Party.

          (d) If the indemnification provided for in this Section 6 is held by a
court of competent jurisdiction to be unavailable to an Indemnified Party with
respect to any loss, liability, claim, damage or expense referred to herein,
then the Indemnifying Party, in lieu of indemnifying the Indemnified Party,
shall contribute to the amount paid or payable by such Indemnified Party with
respect to such loss, liability, claim, damage or expenses in the proportion
that is appropriate to reflect the relative fault of the Indemnifying Party and
the Indemnified Party in connection with the statements or omissions that
resulted in such loss, liability, claim, damage, or expense, as well as any
other relevant equitable considerations. The relative fault of the Indemnifying
Party and the Indemnified Party shall be determined by reference to, among other
things, whether the untrue or alleged untrue statement of material fact or the

                                    - 21 -
<PAGE>
 
omission to state a material fact relates to information supplied by the
Indemnifying Party or by the Indemnified Party, and the parties' relative
intent, knowledge, access to information and opportunity to correct or prevent
such statement or omission.

       7.  Information by Investors. Investors whose Registrable Shares are
           ------------------------                                        
included in any registration shall furnish to the Company such information
regarding themselves and the distribution proposed by them as the Company may
request in writing and as shall be required in connection with any registration,
qualification or compliance referred to in this Agreement.

       8.  Rule 144 Reporting. With a view to making available the benefits of
           ------------------                                                 
certain rules and regulations of the Commission which may at any time permit the
sale of the Registrable Shares to the public without registration, after such
time as a public market exists for the Common Shares and until five years from
the date thereof, the Company shall use reasonably diligent efforts to:

           (a) Make and keep public information available, as those terms are
understood and defined in Rule 144 under the Securities Act, beginning 90 days
after (i) an IPO Event, or (ii) the Company registers a class of securities
under Section 12 of the Securities Exchange Act of 1934, as amended; or

                                    - 22 -
<PAGE>
 
           (b) File with the Commission in a timely manner all reports and other
documents required of the Company under the Securities Act and the Securities
Exchange Act of 1934, as amended (at any time after it has become subject to
such reporting requirements);

           (c) Furnish to any Investor promptly upon request a written statement
as to its compliance with the reporting requirements of Rule 144 (at any time
after 90 days after an IPO Event), and of the Securities Act and the Securities
Exchange Act of 1934 (at any time after it has become subject to such reporting
requirements), a copy of the most recent annual or quarterly report of the
Company, and such other reports and documents of the Company and other
information in the possession of or reasonably obtainable by the Company as an
Investor may reasonably request in availing itself of any rule or regulation of
the Commission allowing an Investor to sell Registrable Shares without
registration.

       9.  Termination of Registration Rights. No Investor shall be entitled to
           ----------------------------------                                  
exercise any right provided for in this Agreement after 7 years following an IPO
event.

       10. Miscellaneous.
           ------------- 

           (a) Amendments and Waivers. The provisions of this Agreement,
               ----------------------                                   
including the provisions of this

                            SUBSCRIPTION AGREEMENT
                            ----------------------

        THIS SUBSCRIPTION AGREEMENT dated as of August 22, 1997 (the 
"Agreement") by and between Software AG Systems, Inc., a Delaware corporation,
(the "Company") and Timothy L. Hill (the "Purchaser").

        WHEREAS, the Purchaser has been elected Vice President, Marketing of the
Company; and

        WHEREAS, the Company and the Purchaser desire to enter into an agreement
pursuant to which the Purchaser will purchase from the Company, and the Company 
will sell to the Purchaser, 500 shares (the "Shares") of the Company's common 
stock;

        NOW, THEREFORE, intending to be legally bound hereby, the parties hereto
agree as follows:

                                  ARTICLE 1.
                        PURCHASE AND SALE OF THE SHARES

             -------------------------------

               (a) The Purchaser will purchase from the Company, and the Company
will issue and sell to the Purchaser, the Shares for an aggregate purchase price
of $202,095 (the "Purchase Price");

               (b) The Company will deliver to the Purchaser a certificate 
representing the Shares; and

               (c) The Purchaser will deliver to the Company a cashier's or 
certified check or wire transfer of funds in the amount of the Purchase Price.

        In connection with the purchase and sale of the Shares hereunder, the 
Purchaser represents and warrants to the Company that:

               (a) The Purchaser is acquiring the Shares for his own account for
investment purposes only and not with a view to, or intention of, making a 
distribution thereof within the meaning of the Securities Act of 1933, as 
amended (the "Act"), or any applicable state securities laws, and the Shares 
will not be transferred


<PAGE>
 
or disposed of in contravention of the Act or any applicable state securities 
laws.

               (b) The Purchaser is aware that the Shares have not been 
registered under the Act or any state or other jurisdiction's securities laws, 
and that the Shares must be held indefinitely unless the sale or other transfer 
thereof is subsequently registered or exemptions from such registration 
requirements are available. The Purchaser is further aware that the Company is 
under no obligation to register the Shares under the Act or any state or other 
jurisdiction's securities laws or to assist the Purchaser is complying with any 
exemption from such registration requirements.

               (c) The Purchaser acknowledges that investment in the Shares 
involves substantial risks, including the risk of total loss of his investment 
in the Shares. The Purchaser (i) is able to bear the economic risk of his 
investment in the Shares for an indefinite period of time; (ii) has adequate 
means, other than the Shares or funds invested therein, of providing for his 
current and foreseeable needs; (iii) has no foreseeable need to sell or 
otherwise dispose of any of the Shares; and (iv) has sufficient net worth to 
sustain a loss of his entire investment in the Shares in the event such loss 
should occur.

               (d) The Purchaser acknowledges that (i) all documents, books and 
records requested by the Purchaser pertaining to the Company or the Shares have 
been made available for inspection by the Purchaser and his agents and 
representatives and (ii) the Purchaser and his agents and representatives have 
had a reasonable opportunity to ask questions of and receive answers from the 
Company or persons acting on behalf of the Company, concerning all matters 
relevant to the Purchaser's decision to purchase Shares.

               (e) The Purchaser is an "accredited investor," as such term is 
defined in Rule 501 under the Act. The Purchaser and his agents and 
representatives have such knowledge and experience in financial and business 
matters as to enable them to utilize the information made available to them in 
connection with the transactions contemplated hereby to evaluate the merits and 
risks of an investment in the Shares and to make an informed decision with 
respect thereto, and such an evaluation and informed decision have been made.

               (f) The Purchaser has the legal capacity and authority to enter 
into and perform all of his obligations under this Agreement. This Agreement 
constitutes the legal, valid and binding obligation of the Purchaser,

violate, cause a breach of or constitute a default under (i) any agreement,
contract or other instrument or obligation to which the Purchaser is a party or 
by which the Purchaser is bound or (ii) any judgment, order, decree, statute, 
rule or regulation to which the Purchaser is subject.

                                  ARTICLE 2.
                         REPURCHASE RIGHT AND NO RAID

        2.1 Company's Repurchase Right.
            --------------------------

               (a) The Purchaser covenants and agrees that, except with the 
prior written consent of the Company, he will not transfer, sell or otherwise 
dispose of, whether directly or indirectly, any of the Shares prior to the later
of (i) the second anniversary of the date hereof and (ii) the ninetieth (90th) 
day following the Termination Date (as defined below), and any purported 
disposition in violation hereof shall be null and void. If prior to the second 
anniversary of the date hereof the Purchaser's employment with the Company is 
terminated for any reason, then within sixty (60) days following the date of 
such termination (the "Termination Date"), the Company may elect, by delivering 
to the Purchaser a written notice of the Company's election, to purchase the 
Shares (including any securities issued in respect of the Shares upon any stock 
split, stock dividend, recapitalization, merger, consolidation or other similar 
event) for a total purchase price equal to the Purchase Price.

               (b) If the Company exercises its right to purchase the Shares 
pursuant to this Section, the Company and the Purchaser shall consummate the 
sale and purchase of the Shares no later than ninety (90) days after the 
Termination Date.

               (c) The Purchaser hereby acknowledges that the right of the

unreasonable under the circumstances existing as of the date hereof.

        2.2 No Raid Covenant.
            ----------------

               (a) The Purchaser agrees that, from the date hereof until five 
years after the termination of the Purchaser's employment with the Company and 
its susidiaries, the Purchaser shall not, directly or indirectly, acting either 
alone or in concert with others, seek to influence any employee of the Company 
or any of its subsidiaries to leave or otherwise terminate such employee's 
employment with such entity. The Purchaser agrees that, from the date hereof 
until three years after the termination of the Purchaser's employment with the 
Company and its subsidiaries, the Purchaser shall not, directly or indirectly, 
solicit or assist any other person in soliciting (other than on behalf of the 
Company and its subsidiaries) any customers, clients or suppliers of the Company
or any of its subsidiaries, provided, however, that the obligations set forth in
this sentence shall not apply to the Purchaser following the termination of the 
Purchaser's employment if such termination is (i) by the Company and (ii) not 
for cause.

               (b) The Purchaser acknowledges that he has carefully read and 
considered all of the terms of this Agreement, including particularly the terms 
of this Section 2.2, that the Company has made a substantial investment in the 
Company's business and that the restrictions provided in this Section 2.2 are 
reasonable and necessary for the Company's protection. The Purchaser further 
acknowledges that damages at law will not be a measurable or adequate remedy for
breach of the covenants contained in this Section, and accordingly the Purchaser
consents to the entry by any court of competent jurisdiction of any order 
enjoining the Purchaser from violating any such covenants. The parties hereto 
further agree that if, in any judicial proceeding, a court should refuse to 
enforce any covenants set forth in this Section 2.2 because of their term or 
geographical scope, then such covenants shall be deemed to be modified to permit
their enforcement to the maximum extent permitted by law.

                                  ARTICLE 3.

                              AMENDMENT AGREEMENT

        THIS AMENDMENT AGREEMENT is made as of October 13, 1997, by and between 
Software AG Systems, Inc., a Delaware corporation (the "Company") and Timothy L.
Hill (the "Purchaser").

        WHEREAS, the Purchaser and the Company have previously entered into a 
Subscription Agreement, dated as of August 22, 1997 (the "Agreement"), pursuant 
to which, the Company may elect to purchase the Shares (as defined in the 
Agreement) from the Purchaser for a total purchase price equal to the Purchase 
Price (as defined in the Agreement) if the Purchaser's employment with the 
Company is terminated for any reason prior to August 22, 1999 (the "Repurchase 
Right"); and

        WHEREAS, the Purchaser and the Company desire to amend the Agreement to 
terminate the Repurchase Right upon a change of control of the Company;

        NOW, THEREFORE, Section 2.1 of the Agreement is hereby amended to read 
in full as follows:

        2.1 Company's Repurchase Right. The Purchaser covenants and agrees that,
            --------------------------
except with the prior written consent of the Company, he will not transfer, sell
or otherwise dispose of, whether directly or indirectly, any of the Shares prior
to the later of (i) August 17, 1999 or (ii) the ninetieth (90th) day following 
the Termination Date (as defined below), and any purported disposition in 
violation hereof shall be null and void. If prior to the earlier of (y) August 
17, 1999 or (z) a Change of Control of the Company, the Purchaser's employment 
with the Company is terminated voluntarily by Purchaser or by the Company for 
cause, then within sixty (60) days following the date of such termination (the 
"Termination Date"), the Company may elect, by delivering to the Purchaser a 
written notice of the Company's election, to purchase the Shares (including any 
securities issued in respect of the Shares upon any stock split, stock dividend,
recapitalization, merger, consolidation or other similar event) for a total 
purchase price equal to the Purchase Price. For purposes of this Section 2.1, 
the term "Change of Control" means the occurrence of any of the following events
after the date hereof: (i) any person or group of persons (as defined in Section
13(d) and 14(d) of the Securities Exchange Act of 1934, as amended (the 
"Exchange Act")) together with its affiliates, excluding affiliates of Thayer 
Equity Investors III, L.P., a
<PAGE>
 
Delaware limited partnership, and employee benefit plans of the Company, 
becomes, directly or indirectly, the "beneficial owner" (as defined in Rule 
13d-3 under the Exchange Act) of securities of the Company representing 51% or 
more of the combined voting power of the Company's then outstanding securities; 
(ii) the stockholders of the Company approve a merger or consolidation of the 
Company with any other corporation or entity regardless of which entity is the 
survivor, other than a merger or consolidation which would result in the voting 
securities of the Company outstanding immediately prior thereto continuing to 
represent (either by remaining outstanding or being converted into voting 
securities of the surviving entity) at least 50% of the combined voting power of
the voting securities of the Company or such surviving entity outstanding 
immediately after such merger or consolidation; or (iii) the stockholders of the
Company approve a plan of complete liquidation or winding-up of the Company or 
an agreement for the sale or disposition by the Company of all or substantially 
all of the Company's assets.

                                  WITNESSETH:

       WHEREAS, pursuant to a Recapitalization Agreement dated as of March 18,
1997, by and among the Company, Thayer, the Managers and Software AG, a German
corporation, Thayer and the Managers purchased from the Company, as of March 31,

       WHEREAS, in connection with such purchase of Common Stock, the Company,
Thayer and the Managers have determined that it is in their respective best
interests to enter into, and perform under, this Agreement;

       NOW, THEREFORE, in consideration of the foregoing and the covenants set

       No Shareholder shall Transfer or cause or permit to be Transferred any
Equity Securities owned or controlled by such Shareholder, except for Transfers
in compliance with Articles 3, 4 and 5 of this Agreement, and any purported

                                   ARTICLE 3.
                            RIGHTS OF FIRST REFUSAL

       Before any Equity Securities owned or controlled by a Shareholder (a
"Selling Shareholder") may be Transferred (other than in a Permitted Transfer or
a Transfer pursuant to Article 4 or 5 hereof) prior to an IPO Event, Thayer and
the Company shall be offered the following rights with respect to such Equity
Securities:

       3.1  Notice. The Selling Shareholder shall first deliver a written notice
            ------                                                              
(a "Shareholder Notice") to the Company and Thayer stating (i) that the Selling
Shareholder desires to Transfer such Equity Securities, (ii) the number and type
of Equity Securities proposed to be Transferred and (iii) the price and other
material terms of the proposed Transfer. The Shareholder Notice shall be
accompanied by a certificate of the Selling Shareholder certifying that it has
received from a third party a bona fide offer to acquire such Equity Securities
at such price and on such terms as are set forth in the Shareholder Notice and
shall identify such third party.

       3.2  Company Right. Within thirty (30) days after receipt of a
            -------------                                            
Shareholder Notice (the "Company Period"), the Company may elect, by delivering
to the Selling Shareholder and to Thayer a written notice (a "Company Notice")
of its election, to purchase all or any part of the Equity Securities to which
the Shareholder Notice refers, on the same terms and conditions specified in
such Shareholder Notice (or on economically equivalent terms and conditions as
determined in good faith by the Company and specified in the Company Notice).
In the event that the Company does not elect to purchase any of such Equity
Securities, the Company shall send a notice to such effect to the Selling
<PAGE>
 
                                     --4--


Shareholder and to Thayer prior to the end of the Company Period.

       3.3  Thayer Right. In the event that the Company does not elect to
            ------------                                                 
purchase during the Company Period all of the Equity Securities to which the
Shareholder Notice refers, then Thayer may elect, by delivering to the Selling
Shareholder a written notice (a "Thayer Notice") of its election within forty-
five (45) days after Thayer's receipt of the Shareholder Notice (the "Thayer
Period"), to acquire, on the same terms and conditions specified in the
Shareholder Notice (or economically equivalent terms and conditions as
determined in good faith by Thayer and specified in the Thayer Notice), any
amount of such Equity Securities that the Company has not elected to purchase.

       3.4  Consummation. In the event that the Company and/or Thayer elects to
            ------------                                                       
acquire Equity Securities pursuant to this Article 3, the Company, Thayer and
the Selling Shareholder shall consummate the sale and purchase of such Equity
Securities within ninety (90) days after the date that the Company and Thayer
have received the Shareholder Notice.

       3.5  Selling Shareholder Right. To the extent the Company and Thayer do
            -------------------------                                         
not exercise their respective rights under this Article 3 within the specified
time periods, the Selling Shareholder may Transfer the Equity Securities
specified in its Shareholder Notice (and not purchased by the Company or Thayer)
to the third party specified in such Shareholder Notice at the price and on the
terms specified in such notice, provided that (i) such Transfer is consummated
within one hundred twenty (120) days of the date of delivery of such Shareholder
Notice and (ii) prior to the Transfer, such third party agrees in writing, in a
form satisfactory to the Company and Thayer, that such third party shall receive
and hold such Equity Securities subject to the provisions of this Agreement.


                                   ARTICLE 4.
                                TAG ALONG RIGHTS

       Until the date of an IPO Event or, if earlier, the date when Thayer's Pro
Rata Share is less than fifty-one percent (51%), Thayer shall not engage in a
transaction (including a merger, consolidation or similar business combination)
that involves the Transfer by Thayer to a third party of Common Stock
representing greater than fifty percent (50%) of the outstanding Equity
Securities (other than a "Drag Along Sale" as defined in Article 5 below and
other than a Transfer to one or more Affiliates of Thayer

<PAGE>
 
                                     - 5 -

and/or Family Members of such Affiliates) without first offering the
Shareholders the right to participate in such Transfer in the following manner:

       4.1  Notice. Thayer shall first deliver a written notice (a "Transfer
            ------                                                          
Notice") to the Shareholders stating (i) Thayer's desire to Transfer Common
Stock to a third party, (ii) the number of Common Stock shares proposed to be
Transferred and (iii) the price and the other general terms of the proposed
Transfer. Such notice may be provided before Thayer has identified a purchaser
or purchasers for such Equity Securities.

       4.2  Shareholders Right. Each Shareholder may elect, by delivering to
            ------------------                                              
Thayer a written notice (a "Tag Along Notice") of its election within fifteen
(15) days after receipt of the Transfer Notice (the "Tag Along Period"), to
participate in Thayer's Transfer of Common Stock on the same terms and
conditions specified in the Transfer Notice. The Tag Along Notice shall specify
the maximum number of Common Stock shares that the Shareholder (a "Tag Along
Shareholder") elects to Transfer which number shall not exceed the product
(rounded down to the nearest whole number) of (i) the percentage of Thayer's Pro
Rata Share that Thayer proposes to Transfer and (ii) the number of shares of
Common Stock owned by the Shareholder. Thayer shall use its best efforts to
interest the third party in purchasing all the Common Stock shares specified by
Tag Along Shareholders in Tag Along Notices, in addition to the Common Stock
that the third party may already have agreed to purchase from Thayer. If the
third party refuses to purchase all of such additional available Common Stock
shares, then Thayer may sell Common Stock to such third party only if Thayer and
each Tag Along Shareholder shall be entitled to sell to such third party an
amount of Common Stock equal to the product (rounded down to the nearest whole
number) obtained by multiplying (x) the aggregate number of Common Stock shares
such third party is willing to acquire by (y) a fraction, the numerator of which
is the number of Common Stock shares proposed to be Transferred by the selling
party in the applicable Tag Along Notice or Transfer Notice, as the case may be,
and the denominator of which is the aggregate number of Common Stock shares
proposed to be Transferred in such notices by Thayer and the Tag Along
Shareholders.

       4.3  Consummation.
            ------------ 

          (a) At least ten (10) days prior to the consummation of a Transfer by
Thayer described in a Transfer Notice and not before the earlier of (x) the end
of the Tag Along Period and (y) the receipt by Thayer of a Tag Along
<PAGE>
 
                                     --6--


Notice from each Shareholder, Thayer shall provide written notice 
(a "Consummation Notice") to each Tag Along Shareholder stating (i) the identity
of the third party transferee, (ii) the number of shares of Common Stock that
such Tag Along Shareholder will be entitled to sell to such third party pursuant
to this Article 4, and (iii) the date the Transfer will be consummated. At least
five (5) days prior to the date of such consummation, each Tag Along Shareholder
shall deliver to Thayer for Transfer to the third party one or more
certificates, properly endorsed for Transfer, which represent the number of
shares of Common Stock such Tag Along Shareholder is entitled to sell as
provided in the Consummation Notice. The certificate(s) delivered to Thayer by
each Tag Along Shareholder shall be Transferred to the third party identified in
the Consummation Notice, as part of the consummation of the Transfer of Common
Stock pursuant to the terms and conditions specified in the Transfer Notice and
the Consummation Notice. Upon receipt of the proceeds of the Transfer, Thayer
shall promptly remit to each Tag Along Shareholder that portion of such proceeds
to which such Tag Along Shareholder is entitled by reason of such Shareholder's
participation in such Transfer.

          (b) In connection with a Transfer pursuant to this Article 4, each Tag
Along Shareholder shall be required to make representations and warranties
regarding the Company and the Common Stock that such Shareholder proposes to
Transfer, including, but not limited to, such Shareholder's ownership of and
authority to Transfer such Common Stock, the absence of any liens or other
encumbrances on such stock, and the compliance of such Transfer with the federal
and state securities laws and all other applicable laws and regulations.

       4.4  Securities Laws. Notwithstanding anything to the contrary in this
            ---------------                                                  
Article 4, Thayer shall have no obligation to permit a Shareholder, and no
Shareholder shall have a right, to participate as a Tag Along Shareholder in a
Thayer Transfer of Common Stock in the event that such Shareholder's Transfer
(i) would not be exempt from all registration requirements under federal and
state securities laws or (ii) would violate, or cause Thayer's Transfer to
violate, any applicable federal or state laws.


                                   ARTICLE 5.
                               DRAG ALONG RIGHTS

       5.1  Drag Along Sale. In the event that, prior to an IPO Event, Thayer,
            ---------------                                                   
in its sole discretion, determines to accept an offer from a third party to
purchase all of the
<PAGE>
 
                                     - 7 -

Common Stock then held by Thayer and the Shareholders, then each Shareholder
shall sell all shares of Common Stock held by such Shareholder pursuant to such
offer (the "Drag Along Sale"). All sellers of Common Stock in such Drag Along
Sale (i) shall receive the same consideration per share of Common Stock and
shall be subject to the same terms and conditions of sale and (ii) shall execute
such documents and take such actions as may be reasonably required by Thayer.

       5.2 Drag Notice. Thayer shall provide each Shareholder with written
           -----------                                                    
notice (the "Drag Notice") of a Drag Along Sale at least fifteen (15) days prior
to the date of consummation of such sale (the "Drag Along Sale Date"). Each
Drag Notice shall set forth: (i) the identity of the third party transferee in
the Drag Along Sale, (ii) the price and the other general terms of the proposed
Transfer and (iii) the Drag Along Sale Date.

       5.3 Form of Consideration. The provisions of this Article 5 shall apply
           ---------------------                                              
regardless of the form of consideration received in the Drag Along Sale, and any
non--cash consideration received pursuant to the terms of the Drag Along Sale
shall be allocated among the transferors of Common Stock pro rata based upon
each transferor's percentage ownership of the Common Stock shares sold in the
Drag Along Sale.

       5.4 Consummation.
           ------------ 

          (a) At least five (5) days prior to the date of consummation of a Drag
Along Sale, each Shareholder shall deliver to Thayer for Transfer to the third
party one or more certificates, properly endorsed for Transfer, which represent
all of the shares of Common Stock held by such Shareholder. The certificate(s)
delivered to Thayer by each Shareholder shall be Transferred to the third party
transferee identified in the Drag Notice, as part of the consummation of the
Drag Along Sale. Upon receipt of the proceeds of the Drag Along Sale, Thayer
shall promptly remit to each Shareholder that portion of such proceeds to which
such Shareholder is entitled by reason of such Shareholder's participation in
such sale.

          (b) In connection with a Drag Along Sale, each Shareholder shall be
required to make representations and warranties regarding the Company and the
Common Stock that such Shareholder Transfers in such sale, including, but not
limited to, such Shareholder's ownership of and authority to Transfer such
Common Stock, the absence of any liens or other encumbrances on such stock, and
the compliance of such Transfer with the federal and state securities laws and
all other applicable laws and regulations.
<PAGE>
 
                                     --8--

          (c) At Thayer's request, each Shareholder shall convert into Common
Stock, or exercise or exchange for Common Stock, some or all (as specified in
Thayer's request) of the outstanding Equity Securities held by such Shareholder
that are convertible into, or exercisable or exchangeable for, Common Stock
prior to or upon the consummation of the Drag Along Sale. Each share of Common
Stock received by a Shareholder upon any such conversion, exercise or exchange
shall be Transferred, subject to the same terms and conditions applicable to all
other shares of Common Stock held by the Shareholders, to the third party
transferee identified in the Drag Notice, as part of the consummation of the
Drag Along Sale.


                                   ARTICLE 6.
                                    NO RAID

       6.1  No Raid Covenant. Each Manager agrees that, from the date hereof
            ----------------                                                
until five years after the termination of such Manager's employment with the
Company and its subsidiaries, such Manager shall not, directly or indirectly,
acting either alone or in concert with others, seek to influence any employee of
the Company or any of its subsidiaries to leave or otherwise terminate such
employee's employment with such entity. Each Manager agrees that, from the date
hereof until three years after the termination of such Manager's employment with
the Company and its subsidiaries, such Manager shall not, directly or
indirectly, solicit or assist any other person in soliciting (other than on
behalf of the Company and its subsidiaries) any customers, clients or suppliers
of the Company or any of its subsidiaries, provided, however, that the
obligations set forth in this sentence shall not apply to a Manager following
the termination of such Manager's employment if such termination is (i) by the
Company and (ii) not for cause.

       6.2 Acknowledgments. Each Manager acknowledges that such Manager has
           ---------------                                                 
carefully read and considered all of the terms of this Agreement, including
particularly the terms of this Article 6, that the Company has made a
substantial investment in the Company's business and that the restrictions
provided in this Article 6 are reasonable and necessary for the Company's
protection. Each Manager further acknowledges that damages at law will not be a
measurable or adequate remedy for breach of the covenants contained in this
Article 6, and accordingly each Manager consents to the entry by any court of
competent jurisdiction of any order enjoining such Manager from violating any
such covenants. The parties hereto further agree that if, in any
<PAGE>
 
                                     - 9 -


judicial proceeding, a court should refuse to enforce any covenants set forth in
this Article 6 because of their term or geographical scope, then such covenants
shall be deemed to be modified to permit their enforcement to the maximum extent
permitted by law.


                                  ARTICLE 7.
                        TERMINATION; ADDITIONAL PARTIES

       7.1   Termination. All rights and obligations set forth in this Agreement
             -----------                                                        
(other than in Article 6), to the extent not previously terminated, shall
terminate upon an IPO Event.

       7.2   Additional Parties. Without the prior written consent of Thayer, 
             ------------------
the Company shall not issue or sell after the date hereof, any shares of Common
Stock to any individual or entity without such individual or entity becoming a
party to this Agreement by agreeing in writing to be bound by the terms hereof.
Any such additional party shall become a Shareholder subject to and bound by all
the terms and conditions of this Agreement. The Company shall promptly notify
each existing party to this Agreement of the addition of each new party hereto
and such notice shall include the requisite information for providing notice to
such new party pursuant to Section 8.6.
