                                  PART I

ITEM 1:  BUSINESS

THIS ITEM CONTAINS CERTAIN FORWARD-LOOKING STATEMENTS WITHIN THE MEANING OF 
SECTION 27A OF THE SECURITIES ACT OF 1933 AND SECTION 21E OF THE SECURITIES 
EXCHANGE ACT OF 1934.  THE COMPANY'S ACTUAL RESULTS COULD DIFFER MATERIALLY 
FROM THE RESULTS ANTICIPATED IN THESE FORWARD-LOOKING STATEMENTS AS A RESULT 
OF CERTAIN FACTORS SET FORTH IN "MANAGEMENT'S DISCUSSION AND ANALYSIS OF 
FINANCIAL CONDITION AND RESULTS OF OPERATIONS" AND ELSEWHERE IN THIS REPORT.

A.  BACKGROUND

     Organizations face financial risks from changes in interest and foreign 
exchange rates, changes in the commodity and equity markets, credit exposure 
and liquidity. The risk exposure has increased with the globalization of the 
world's economy and other factors. To help organizations manage these risks, 
the financial industry has developed a variety of specialized financial 
contracts, such as swaps, options, caps, floors, swaptions and futures, 
collectively known as "derivative instruments." Interest rate swaps, for 
example, allow a company to insure against unfavorable movements in interest 
rates by exchanging variable interest rate exposure for a fixed interest 
rate. 

     The need to manage financial risk has led to the development of software 
products that serve the established market for derivatives risk management 
and the markets for firm-wide or enterprise risk management.

     C-ATS Software Inc., a Delaware corporation (the "Company" or "C-ATS") 
is a supplier of client/server software products for financial risk 
management. Since its inception in 1986, the Company has provided capital 
markets software for derivatives risk management. In late 1994, the Company 
introduced C-ATALYST, an enhanced version of its product family which 
includes GLOBAL RISK MANAGER, a product for portfolio risk management.  In 
1996, the Company acquired LOR/Geske Bock Associates, Inc. ("LORGB" or 
LOR/Geske Bock"), a provider of integrated market 
and credit risk management software, and introduced an enhanced version of 
its CARMA product line. These products serve the established market for 
derivatives risk management and the growing market for enterprise risk 
management. At the end of 1997, the Company's products were licensed to 
leading financial institutions around the globe, including more than a third 
of the world's 50 largest commercial banks.

     C-ATS' C-ATALYST product line is used in derivatives risk management to 
provide "front office" software for structuring, pricing, trading and 
simulating complex derivative instruments such as swaps, options, caps, 
floors, swaptions and futures, and "back office" software for processing, 
settlement, accounting and reporting.  C-ATS' GLOBAL RISK MANAGER supports 
risk management of individual portfolios by allowing users to value their 
portfolios and to analyze the sensitivity of those portfolios to interest 
rates, foreign exchange rates and other risks. The Company's clients use 
these products on UNIX workstations and on personal computers. 

     C-ATS' CARMA product line is a portfolio simulation system designed to 
provide multiple market, credit, and liquidity risk measurement methodologies 
within one consistent, integrated solution. CARMA enables financial 
institutions to measure and control the change in value of financial 
instruments, including complex derivative instruments, and to measure the 
firm-wide 

                                   2

<PAGE>

exposure to market and credit risk. The software assists with the 
determination of capital requirements and regulatory reporting of Value at 
Risk (VaR) using both Monte Carlo and historical simulation techniques. In 
addition, CARMA provides user-defined scenario analyses to realistically 
forecast the effects on a portfolio subjected to a combination of multiple 
types of financial risks. Users can graphically visualize the results of the 
potential effects of any component on the entire portfolio in order to 
understand more fully how to manage the risks involved.

     The Company typically licenses its software products to clients for 
one-year renewable terms.  Beginning the fourth quarter of 1997, the Company 
has begun offering multiyear (typically 5-year) term licenses for its 
software products. With this new licensing model the Company will recognize 
substantial revenues upon delivery of the products.  In addition there may be 
additional maintenance revenues, recognized ratably as such services are 
provided.  

     C-ATS markets its products and services through its direct sales and 
service organizations located in New York, Tokyo, London, Hong Kong and its 
headquarters and financial engineering facilities in Palo Alto and Los 
Angeles, California, respectively. Those clients whose use of Company's 
products has been publicly disclosed include Bank of Montreal, Cassa di 
Risparmio di Torino, Credit Suisse, Dai-ichi Kangyo Bank, Daiwa America 
Corp., IMI Bank, Kleinwort-Benson, Long-Term Capital Management, Merrill 
Lynch, Bank of Tokyo-Mitsubishi and Tokai Bank, each of which represented 
more than $100,000 of annual contract value in 1997.  In 1997, 82% of the 
Company's revenues were derived from international clients.

     In the Fall of 1997, the Company formed a new division C-ATS Consulting 
Services to provide professional services to its clients.  These services 
will typically include project management and product integration services.  
Consulting revenues are recognized when the services have been performed.

B.  PRODUCTS.

     C-atalyst is a family of integrated application software products and 
tools used for financial risk management. All of these products were either 
introduced or enhanced in 1997.

     The Company's clients use its products on UNIX workstations and on 
personal computers. FiCAD is used on the NEXTSTEP-TM- operating system to 
design new financial instruments and applications.  The Company licenses its 
products on a per site basis, with the price per site varying based on the 
selection of products licensed, the number of authorized users at each site, 
and the number of licensed sites. 

     The Company's products, once installed, generally must be integrated 
with the client's internal information systems, especially in the case of 
large enterprise-wide implementations. This integration can be costly, 
time-consuming and require significant technical expertise, particularly when 
multiple sites, a variety of internal systems and/or international locations 
are involved.

PRODUCTS FOR DERIVATIVES RISK MANAGEMENT

     SWAPWARE PLUS.  SWAPWARE PLUS prices and models a broad spectrum of 
swaps, from the simplest interest rate swap to complex currency and commodity 
swaps and highly sophisticated structures and basis swaps. Through its cash 
flow architecture and six-level hierarchy for reset computations, SWAPWARE 
PLUS also models foreign exchange, debt and cash transactions, while 
providing accurate portfolio revaluations and risk management support. 
SWAPWARE was the Company's first product and is used by substantially all of 
its clients. 

     MARKET DATA.  MARKET DATA provides the market and pricing data for 
C-ATALYST software applications and can be used with applications developed 
with FiCAD. MARKET DATA is a tool for inputing currency and interest rates as 
well as bonds and futures prices, forward, equity and commodity prices, swap 
spreads and money market rates needed to generate par, zero, synthetic 
blended curves, and other price data.  MARKET DATA contains a central archive 
for international market prices and yields, multiple instrument support and a 
historical database.  In addition, MARKET DATA constructs open, flexible 
yield curves which allow for user-definition.

                                       4

     DATA TOOLS.  DATA TOOLS is a set of data import and export utilities, 
including a real-time data feed, tools to generate reports and protect 
information, and an audit trail to increase control and includes the 
following modules:  C-ATS Link, SQL Mirror, C-ATS-IQ Reports and Shadow Audit.

     OPERATIONS MANAGER-ACCOUNTING. ACCOUNTING works with SWAPWARE PLUS, 
OPTIONS, and FUTURES AND BONDS to generate profit and loss statements.  
Accounting can also be used to automate payment processing, counterparty 
notifications and regulatory reports. 

     OPERATIONS MANAGER-CASH FLOW ORGANIZER.  CASH FLOW ORGANIZER works with 
SWAPWARE PLUS, OPTIONS, and FUTURES AND BONDS to define complex quote, reset 
and fixing structures, and calculate and process bulk resets, rate fixings 
and rate reset notifications.

     OPTIONS-CAPWARE.  CAPWARE prices and models an extensive selection of 
options, including fixed and variable rate caps, floors and forward rate 
agreements (FRAs). CAPWARE utilizes the Black-Scholes options pricing models.

     OPTIONS-STRIKE.   STRIKE prices and models "swaptions" (options to 
execute a swap) and bond options. STRIKE also supports receiver and payor 
swaptions, swap cancellations and puts and calls on fixed-income securities. 
STRIKE utilizes the Black-Scholes, Black-Commodity and Hull-White options 
pricing models.

     FUTURES AND BONDS.  FUTURES AND BONDS prices and models an array of 
futures contracts, as well as a broad range of government and corporate bonds 
and Eurobonds across international markets. FUTURES AND BONDS employs bond 
definition characteristics that combine a flexible modeling capacity with 
coverage of most major bond markets. 

     C-ATS/GLI. C-ATS/GENERAL LEDGER INTERFACE (GLI) is an open tool which 
creates a complete accounting record for the C-ATALYST portfolio, and allows 
the transfer of this information automatically to the general ledger.  
C-ATS/GLI includes manual and system generated entries, a multi-currency 
trial balance and a detail report.

     C-ATS/FX. C-ATS/FX is a foreign exchange trading, marketing, risk 
management and back office module.  C-ATS/FX prices spots, forwards, and an 
array of exotic options including Asian options, lookbacks, single and double 
barriers.  It also has extensive graphing capabilities for payout and 
sensitivity analysis. 

     FiCAD.  FiCAD is an object-oriented Financial CAD system which uses 
advanced visual programming techniques. FiCAD enables users to design, model 
and deploy new financial instruments that the user can logically define.  
FiCAD is analogous to the mechanical CAD products and electronic design 
automation ("EDA") products provided by independent software vendors for other 
industries. With EDA, an engineer describes logic networks with graphic 
symbols, and the software program automatically generates the layout for 
semiconductor chips. FiCAD enables users to link together various financial 
objects to describe a new financial instrument, and FiCAD automatically 
creates the new application; there is no need to write traditional text-based 
source code.  As a result, the Company believes that new instruments can be 
created much more rapidly than is possible with conventional techniques.  
FiCAD allows its clients to extend the functionality of the C-ATALYST product 
line in advance of new releases. GLOBAL RISK MANAGER and FiCAD, are also used 
in derivatives risk management.

                                       5

<PAGE>

PRODUCTS FOR ENTERPRISE RISK MANAGEMENT 

     GLOBAL RISK MANAGER.  GLOBAL RISK MANAGER can be used both for 
derivatives risk management and for firm-wide risk management. GLOBAL RISK 
MANAGER allows the user to link standard and custom financial instruments to 
evaluate risk levels for a single transaction or an entire portfolio. In 
addition to evaluating interest rate and foreign exchange risks, GLOBAL RISK 
MANAGER also evaluates new types of risk defined by users. GLOBAL RISK 
MANAGER utilizes mathematical and database analysis techniques, accurate 
mark-to-market and hedging capabilities and risk scenario analysis. GLOBAL 
RISK MANAGER permits users to define their sensitivity to interest rates, 
foreign exchange rates, delta, gamma/convexity, theta, vega and duration. 
GLOBAL RISK MANAGER also manages funds liquidity.

     GLOBAL RISK MANAGER links to the various position-keeping systems that 
the client uses for different portions of its portfolio. These may include 
C-ATALYST products such as SWAPWARE PLUS or other systems developed 
internally or licensed from third parties.

     CARMA.  CARMA simulates a financial institution's exposure to market and 
credit risk using multiple methodologies.  Through Monte Carlo simulation or 
historical simulation, CARMA measures and reports the financial institution's 
exposure to changes in market prices and counterparty defaults.  The system 
is designed to comply with the standards for measurement of exposure to 
market risk promulgated by the Bank for International Settlements (BIS).  
CARMA became part of the Company's product line through the acquisition of 
LOR/Geske Bock in February 1996.  The Company has substantially enhanced 
CARMA and released version 2.16 in 1997.

C.  CLIENTS, MARKETING, SALES AND SERVICE

     The Company's products are licensed to leading financial institutions 
around the globe. These clients operate in a number of industries and include 
more than a third of the world's 50 largest commercial and investment banks, 
as well as securities firms, fund managers, and large industrial corporations 
and insurance companies.

     Those clients whose use of Company products has been publicly disclosed 
include Bank of Montreal, Cassa di Risparmio di Torino, Credit Suisse, 
Dai-ichi Kangyo Bank, Daiwa America Corp., IMI Bank, Kleinwort-Benson, 
Long-Term  Capital Management, Merrill Lynch, Bank of Tokyo-Mitsubishi, and 
Tokai Bank, each of which represented more than $100,000 of annual contract 
value in 1997. In 1997, 82% of the Company's revenues were derived from 
international clients.  

     C-ATS employs a direct sales force and client services organization 
located in New York, Tokyo, Hong Kong, and London.  In support of its sales 
force, the Company uses a variety of means to promote its software products 
to potential clients, including advertising, articles in key publications, 
direct mail, participation in major industry trade shows, and seminars. 
Additionally, the Company is an associate member of the International Swaps 
and Derivatives Association. 

     The Company previously did not utilize value-added resellers or other 
third-party distributors. During 1997, the Company began evaluation of using 
such services and commenced a relationship with two such parties.  This 
program is new and there are not yet conclusive results.  The Company may 
expand such efforts in 1998.

     The Company's client services personnel provide pre-sale assistance in 
applications engineering, product installation and client training, both on 
the clients' premises and in classrooms, and provide post-sale service and 
support in problem diagnosis. Product licenses also entitle clients to 

                                       6

<PAGE>

receive updates and minor enhancements. The Company typically supports prior 
versions of its products for a reasonable period to allow clients to upgrade 
at the time they deem most convenient for their installation. The Company 
provides certain professional services to clients on a contract basis, 
including financial engineering support, additional client training and 
assistance in the generation of client-specific reports, database 
integration, and system optimization. The Company also conducts periodic 
client satisfaction surveys.

     In the Fall of 1997, the Company formed a new division C-ATS Consulting 
Services to provide a wide variety of services to ensure client success in 
implementing risk management solutions.  By leveraging project experiences 
gained through delivering complete enterprise-wide risk management solutions, 
this group provides clients with services specifically targeted at lowering 
implementation risks.

     C-ATS Consulting Services is responsible for CARMA implementation 
projects globally for C-ATS Software.  The group began providing its clients 
with generic enterprise risk management implementation project plan 
templates, integration tools and additional integration assistance and advice 
in 1997 and is currently engaged in several ongoing risk management projects. 

     The operations in Tokyo and London are conducted by wholly-owned 
subsidiaries incorporated in Japan and the United Kingdom, respectively. The 
subsidiaries conduct sales representative activities under the direction of 
the parent company. The subsidiaries also conduct some client training and 
share responsibility with the parent for performing certain other client 
service activities, although all software engineering is performed by the 
parent company. All license agreements are entered into between the parent 
company and the clients. All clients pay their license and service fees 
directly to the parent company in U.S. dollars. All parent company revenues 
are recognized as either domestic or export sales. Subsidiary revenues 
consist solely of payments from the parent company for services performed for 
the benefit of the parent company at a rate of cost plus 10%. 

D.  TECHNOLOGY

     FINANCIAL TECHNOLOGIES, VALUE AT RISK.  VALUE AT RISK has become an 
industry standard for risk management and regulatory reporting. Value at Risk 
represents the amount of money a portfolio may lose in a given period of time 
at a specified probability level. This amount varies based on the instruments 
in a portfolio, changes in market prices and volatilities. A firm's Value at 
Risk is calculated using estimates of likely price fluctuations of its 
portfolio. The Company's products can be used to perform the simulations 
necessary to support Value at Risk analysis. This calculation can be 
performed on a departmental or enterprise basis.

     CASH FLOW ARCHITECTURE.  In 1986, the Company introduced SWAPWARE, which 
it believes was the first commercially available product that defined 
financial instruments using cash flow architecture. The Company subsequently 
enhanced its cash flow architecture by adding capability for six-level 
hierarchical reset computations. This architecture can be used to calculate 
the cash flows for a wide range of instruments across international markets, 
and is fully integrated with the Company's products' pricing and risk 
management functions.

E.  COMPETITION

     The market for financial risk management software is intensely 
competitive and is characterized by rapid technological change and frequent 
introduction of new products and features. The Company competes generally on 
the basis of product features and functions, product architecture, price, the 
speed and accuracy of the product processing capability, client service, the 
availability of sufficiently trained technical staff, and the vendor 
financial stability. In order to maintain or improve its position in this 
industry, the Company must continue to enhance its current products and 
develop new products in a timely fashion. Because of the complexity of the 
Company's products, from time to time development efforts have taken longer 
than expected, causing delays in new products and enhancement releases, and 
this may occur in the future. Any such delays could have a material adverse 
effect on the Company's business, operating results or financial condition. 

     A major source of competition for the Company's products are 
applications that are internally developed by the financial institutions 
which are its potential clients. Many of these organizations have substantial 
internal development resources with the capability to develop specific 
products for their needs. Many of these organizations also value the ability 
to control the source code for their software systems. The Company does not 
typically make its source code available. The Company believes that its 
products offer a number of advantages over internally developed alternatives, 
including more rapid time-to-market, lower cost and more systematic and 
complete reliability testing. 

     There are a significant number of independent commercial competitors for 
the Company's products.  In 1997, the competitive landscape was characterized 
by significant consolidation by some of the larger competitors, these include 
the recent merger of SunGard Data Systems Inc. with Infinity Financial 
Technologies, Inc. and Renaissance Software, Inc., Misys Plc Group's 
Midas-Kapiti International and Summit Systems, Inc. merger as well as ACT 
Group plc., are much larger than the Company and have longer operating 
histories and significantly greater financial, technical, sales and marketing 
and other resources, greater name recognition and a larger installed client 
base. 

     Other competitors offer products that support more financial instruments 
or have more features than the Company's products, some offer more 
customization services, some offer source code and programming tools for 
internal application development.  Many of the Company's existing competitors 
could in the future introduce new products with more features and lower 
prices than the Company's product offerings. Furthermore, if the market for 
financial risk management software products continues to grow, a number of 
additional companies with significantly greater resources than the Company 
could attempt to establish or increase their presence in this market by 
acquiring or forming strategic alliances with competitors of the Company, as 
evidenced in 1997, or by developing and introducing products specifically 
designed for these markets. 

     Despite this intensely competitive environment, the Company believes 
that it competes favorably in its markets on the basis of product 
functionality, price, performance characteristics, ease of product use, sales 
and marketing expertise, financial stability, client support services and 
corporate reputation.

F.  PROPRIETARY RIGHTS

     The Company relies on a combination of copyright, patent rights, trade 
secret and trademark laws, license agreements and software security measures 
to protect its proprietary technology and software products. The Company has 
applied for a U.S. patent for its financial CAD technology. The Company's 
patent application seeks protection for an object-oriented system for 
creating, structuring,

                                       8

<PAGE>

manipulating and evaluating financial instruments. However, there can be no 
assurance that the patent will be granted. 

     Despite these precautions, it may be possible for a third party to 
independently develop the same or similar technology or otherwise obtain 
access to the Company's proprietary technology.  In addition, the Company 
does not currently possess, and has not applied for, any foreign patents. 
Moreover, the Company cannot be certain that others will not independently 
develop substantially equivalent or superseding proprietary technology, or 
that an equivalent product will not be marketed in competition with the 
Company's products, thereby substantially reducing the value of the Company's 
proprietary rights. There can be no assurance that any confidentiality 
agreements between the Company and its employees will provide meaningful 
protection for the Company's proprietary information in the event of any 
unauthorized use or disclosure of such proprietary information. Although most 
all of the Company's software product license agreements with its clients 
protect the Company's proprietary information under the laws and jurisdiction 
of the State of California where significant case law exists to protect such 
information, the local laws of certain countries in which the Company's 
products are licensed do not protect the Company's products and intellectual 
property rights to the same extent. The Company believes that, due to the 
rapid pace of innovation within the industry, factors such as the 
technological and creative expertise of its personnel, the quality of its 
products, the quality of its technical support and training courses, and the 
frequency of its software product enhancements are more important to 
establishing and maintaining a technology leadership position within the 
industry than the various legal protections for its products and technology.  

G.  EMPLOYEES

     As of December 31, 1997, the Company and its subsidiaries had a total of 
110 employees, including  40 in product development, 53 in sales, marketing 
and client services, and 17 in finance and administration. None of the 
Company's employees are represented by a labor union. The Company has 
experienced no work stoppages and believes that its employee relationships 
are good.

     We have audited, in accordance with generally accepted auditing 
standards, the financial statements included in  C-ATS Software Inc.'s annual 
report to shareholders, incorporated by reference in this Form 10-K, and have 
issued our report thereon dated January 23, 1998. Our audit was made for the 
purpose of forming an opinion on the basic financial statements taken as a 
whole. The schedule listed in the index above is the responsibility of the 
Company's management and is presented for purposes of complying with the 
Securities and Exchange Commission's rules and is not part of the basic 
financial statements. This schedule has been subjected to the auditing 
procedures applied in the audit of the basic financial statements and, in our 
opinion, fairly states in all material respects the financial data required 
to be set forth therein in relation to the basic financial statements taken 
as a whole.

                               (a Delaware corporation)

                        (As amended through November 19, 1997)


                                      ARTICLE I

     2.1  PLACE OF MEETINGS

     Meetings of stockholders shall be held at any place within or outside

principal executive office of the corporation.

     2.2  ANNUAL MEETING

     The annual meeting of stockholders shall be held each year on a date and 
at a time designated by the board of directors.  In the absence of such 
designation, the annual meeting of stockholders shall be held on the third

<PAGE>

     2.3  SPECIAL MEETING

     A special meeting of the stockholders may be called at any time by the 
board of directors, or by the chairman of the board, or by the president, or 
by one or more stockholders holding shares in the aggregate entitled to cast 
not less than ten percent (10%) of the votes of all shares of stock owned by 
stockholders entitled to vote at that meeting.

     If a special meeting is called by any person or persons other than the 
board of directors or the president or the chairman of the board, then the 
request shall be in writing, specifying the time of such meeting and the 
general nature of the business proposed to be transacted, and shall be 
delivered personally or sent by registered mail or by telegraphic or other 
facsimile transmission to the chairman of the board, the president, any vice 
president or the secretary of the corporation.  The officer receiving the 
request shall cause notice to be promptly given to the stockholders entitled 
to vote, in accordance with the provisions of Sections 2.4 and 2.6 of these 
bylaws, that a meeting will be held at the time requested by the person or 
persons calling the meeting, so long as that time is not less than 
thirty-five (35) nor more than sixty (60) days after the receipt of the 
request.  If the notice is not given within twenty (20) days after receipt of 
the request, then the person or persons requesting the meeting may give the 
notice.  Nothing contained in this paragraph of this Section 2.3 shall be 
construed as limiting, fixing or affecting the time when a meeting of 
stockholders called by action of the board of directors may be held.

     2.4  NOTICE OF STOCKHOLDERS' MEETINGS

     All notices of meetings of stockholders shall be sent or otherwise given 
in accordance with Section 2.6 of these bylaws not less than ten (10) nor 
more than sixty (60) days before the date of the meeting.  The notice shall 
specify the place, date and hour of the meeting and (i) in the case of a 
special meeting, the purpose or purposes for which the meeting is called (no 
business other than that specified in the notice may be transacted) or (ii) 
in the case of the annual meeting, those matters which the board of 
directors, at the time of giving the notice, intends to present for action by 
the stockholders (but any proper matter may be presented at the meeting for 
such action).  The notice of any meeting at which directors are to be elected 
shall include the name of any nominee or nominees who, at the time of the 
notice, the board intends to present for election.

     (b)  business proposed to be brought before any stockholder meeting 

                                       -2-

<PAGE>

may be made by the board of directors or proxy committee appointed by the 
board of directors or by any stockholder entitled to vote in the election of 
directors generally if such nomination or business proposed is otherwise 
proper business before such meeting.  However, any such stockholder may 
nominate one or more persons for election as directors at a meeting or 
propose business to be brought before a meeting, or both, only if such 
stockholder has given timely notice in proper written form of their intent to 
make such nomination or nominations or to propose such business.  To be 
timely, such stockholder's notice must be delivered to or mailed and received 
by the secretary of the corporation not less than ninety (90) days prior to 
the meeting; provided, however, that in the event that less than one-hundred 
(100) days notice or prior public disclosure of the date of the meeting is 
given or made to stockholders, notice by the stockholder to be timely must be 
so received not later than the close of business on the tenth day following 
the day on which such notice of the date of the meeting was mailed or such 
public disclosure was made.  To be in proper form, a stockholder's notice to 
the secretary shall set forth:

     (i)       the name and address of the stockholder who intends to make the
     nominations or propose the business and, as the case may be, of the person
     or persons to be nominated or of the business to be proposed;

     (ii)      a representation that the stockholder is a holder of record of
     stock of the corporation entitled to vote at such meeting and, if
     applicable, intends to appear in person or by proxy at the meeting to
     nominate the person or persons specified in the notice;

     (iii)     if applicable, a description of all arrangements or
     understandings between the stockholder and each nominee and any other
     person or persons (naming such person or persons) pursuant to which the
     nomination or nominations are to be made by the stockholder;

     (iv)      such other information regarding each nominee or each matter of
     business to be proposed by such stockholder as would be required to be
     included in a proxy statement filed pursuant to the proxy rules of the
     Securities and Exchange Commission had the nominee been nominated, or
     intended to be nominated, or the matter been proposed, or intended to be
     proposed by the board of directors; and

     (v)       if applicable, the consent of each nominee to serve as director
     of the corporation if so elected.

     The chairman of the meeting shall refuse to acknowledge the nomination 
of any person or the proposal of any business not made in compliance with the 
foregoing procedure.

     2.6  MANNER OF GIVING NOTICE; AFFIDAVIT OF NOTICE

     Written notice of any meeting of stockholders shall be given either
personally or by first-class mail or by telegraphic or other written
communication.  Notices not personally delivered shall be sent

charges prepaid and shall be addressed to the stockholder at the address of

in the mail or sent by telegram or other means of written communication.

     An affidavit of the mailing or other means of giving any notice of any 
stockholders' meeting, executed by the secretary, assistant secretary or any 
transfer agent of the corporation giving the notice, shall be prima facie 
evidence of the giving of such notice.

     2.7  QUORUM

     The holders of a majority in voting power of the stock issued and 
outstanding and entitled to vote thereat, present in person or represented by 
proxy, shall constitute a quorum at all meetings of the stockholders for the 
transaction of business except as otherwise provided by statute or by the 
certificate of incorporation.  If, however, such quorum is not present or 
represented at any meeting of the stockholders, then either (i) the chairman 
of the meeting or (ii) the stockholders entitled to vote thereat, present in 
person or represented by proxy, shall have power to adjourn the meeting in 
accordance with Section 2.7 of these bylaws.

     When a quorum is present at any meeting, the vote of the holders of a 
majority of the stock having voting power present in person or represented by 
proxy shall decide any question brought before such meeting, unless the 
question is one upon which, by express provision of the laws of the State of 
Delaware or of the certificate of incorporation or these bylaws, a different 
vote is required, in which case such express provision shall govern and 
control the decision of the question.

     If a quorum be initially present, the stockholders may continue to 
transact business until adjournment, notwithstanding the withdrawal of enough 
stockholders to leave less than a quorum, if any action taken is approved by 
a majority of the stockholders initially constituting the quorum.

     2.8  ADJOURNED MEETING; NOTICE

     When a meeting is adjourned to another time and place, unless these 
bylaws otherwise require, notice need not be given of the adjourned meeting 
if the time and place thereof are announced at the meeting at which the 
adjournment is taken.  At the adjourned meeting the corporation may transact 
any business that might have been transacted at the original meeting.  If the 
adjournment is for more than thirty (30) days, or if after the adjournment a 
new record date is fixed for the adjourned meeting, a notice of the adjourned 
meeting shall be given to each stockholder of record entitled to vote at the 
meeting.

     2.9  VOTING

     The stockholders entitled to vote at any meeting of stockholders shall be
determined in accordance with the provisions of Section 2.11 of these bylaws,
subject to the provisions of Sections 217 

                                       -4-

<PAGE>

and 218 of the General Corporation Law of Delaware (relating to voting rights 
of fiduciaries, pledgors and joint owners, and to voting trusts and other 
voting agreements).

     Except as may be otherwise provided in the certificate of incorporation 
or these bylaws, each stockholder shall be entitled to one vote for each 
share of capital stock held by such stockholder.

     At a stockholders' meeting at which directors are to be elected, and to 
the extent permitted by the corporation's Certificate of Incorporation, each 
stockholder shall be entitled to cumulate votes (i.e., cast for any candidate 
a number of votes greater than the number of votes that such stockholder 
normally is entitled to cast) if the candidates' names have been properly 
placed in nomination (in accordance with these bylaws) prior to commencement 
of the voting, and the stockholder requesting cumulative voting has given 
notice prior to commencement of the voting of the stockholder's intention to 
cumulate votes. If cumulative voting is properly requested, each holder of 
stock, or of any class or classes or of a series or series thereof, who 
elects to cumulate votes shall be entitled to as many votes as equals the 
number of votes that (absent this provision as to cumulative voting) he or 
she would be entitled to cast for the election of directors with respect to 
his or her shares of stock multiplied by the number of directors to be 
elected by him, and he or she may cast all of such votes for a single 
director or may distribute them among the number to be voted for, or for any 
two or more of them, as he or she may see fit.

     2.10 STOCKHOLDER ACTION BY WRITTEN CONSENT WITHOUT A MEETING

     Unless otherwise provided in the Certificate of Incorporation, any 
action required or permitted to be taken at any annual or special meeting of 
stockholders may be taken without a meeting, without prior notice and without 
a vote, if a consent or consents in writing setting forth the action so 
taken, shall be signed by the holders of outstanding stock having not less 
than the minimum number of votes that would be necessary to authorize or take 
such action at a meeting at which all shares entitled to vote thereon were 
present and voted.  Such consents shall be delivered to the corporation by 
delivery to it registered office in the state of Delaware, its principal 
place of business, or an officer or agent of the corporation having custody 
of the book in which proceedings of meetings of stockholders are recorded.  
Delivery made to a corporation's registered office shall be by hand or by 
certified or registered mail, return receipt requested.

     2.11 RECORD DATE FOR STOCKHOLDER NOTICE; VOTING

     For purposes of determining the stockholders entitled to notice of any 
meeting or to vote thereat, the board of directors may fix, in advance, a 
record date, which shall not precede the date upon which the resolution 
fixing the record date is adopted by the board of directors and which shall 
not be more than sixty (60) days nor less than ten (10) days before the date 
of any such meeting, and in such event only stockholders of record on the 
date so fixed are entitled to notice and to vote, notwithstanding any 
transfer of any shares on the books of the corporation after the record date.

                                       -5-

<PAGE>

     If the board of directors does not so fix a record date, the record date 
for determining stockholders entitled to notice of or to vote at a meeting of 
stockholders shall be at the close of business on the business day next 
preceding the day on which notice is given, or, if notice is waived, at the 
close of business on the business day next preceding the day on which the 
meeting is held.

     A determination of stockholders of record entitled to notice of or to 
vote at a meeting of stockholders shall apply to any adjournment of the 
meeting unless the board of directors fixes a new record date for the 
adjourned meeting, but the board of directors shall fix a new record date if 
the meeting is adjourned for more than thirty (30) days from the date set for 
the original meeting.

     The record date for any other purpose shall be as provided in Section 
8.1 of these bylaws.

     2.12 PROXIES

     Every person entitled to vote for directors, or on any other matter, 
shall have the right to do so either in person or by one or more agents 
authorized by a written proxy signed by the person and filed with the 
secretary of the corporation, but no such proxy shall be voted or acted upon 
after three (3) years from its date, unless the proxy provides for a longer 
period.  A proxy shall be deemed signed if the stockholder's name is placed 
on the proxy (whether by manual signature, typewriting, telegraphic 
transmission, telefacsimile or otherwise) by the stockholder or the 
stockholder's attorney-in-fact.  The revocability of a proxy that states on 
its face that it is irrevocable shall be governed by the provisions of 
Section 212(e) of the General Corporation Law of Delaware.

     2.13 ORGANIZATION

     The president, or in the absence of the president, the chairman of the 
board, shall call the meeting of the stockholders to order, and shall act as 
chairman of the meeting.  In the absence of the president, the chairman of 
the board, and all of the vice presidents, the stockholders shall appoint a 
chairman for such meeting.  The chairman of any meeting of stockholders shall 
determine the order of business and the procedures at the meeting, including 
such matters as the regulation of the manner of voting and the conduct of 
business.  The secretary of the corporation shall act as secretary of all 
meetings of the stockholders, but in the absence of the secretary at any 
meeting of the stockholders, the chairman of the meeting may appoint any 
person to act as secretary of the meeting.

     2.14 LIST OF STOCKHOLDERS ENTITLED TO VOTE

     The officer who has charge of the stock ledger of the corporation shall
prepare and make, at least ten (10) days before every meeting of stockholders, a
complete list of the stockholders entitled to vote at the meeting, arranged in
alphabetical order, and showing the address of each stockholder and the number
of shares registered in the name of each stockholder.  Such list shall be open
to the examination of any stockholder, for any purpose germane to the meeting,
during ordinary business hours, for a period of at least ten (10) days prior to
the meeting, either at a place within the city where the meeting is to be 


                                       -6-

<PAGE>

held, which place shall be specified in the notice of the meeting, or, if not 
so specified, at the place where the meeting is to be held.  The list shall 
also be produced and kept at the time and place of the meeting during the 
whole time thereof, and may be inspected by any stockholder who is present.

     2.15 WAIVER OF NOTICE

     Whenever notice is required to be given under any provision of the 
General Corporation Law of Delaware or of the certificate of incorporation or 
these bylaws, a written waiver thereof, signed by the person entitled to 
notice, whether before or after the time stated therein, shall be deemed 
equivalent to notice.  Attendance of a person at a meeting shall constitute a 
waiver of notice of such meeting, except when the person attends a meeting 
for the express purpose of objecting, at the beginning of the meeting, to the 
transaction of any business because the meeting is not lawfully called or 
convened.  Neither the business to be transacted at, nor the purpose of, any 
regular or special meeting of the stockholders need be specified in any 
written waiver of notice unless so required by the certificate of 
incorporation or these bylaws.

                                     ARTICLE III

                                      DIRECTORS

     3.1  POWERS

     Subject to the provisions of the General Corporation Law of Delaware and 
to any limitations in the certificate of incorporation or these bylaws 
relating to action required to be approved by the stockholders or by the 
outstanding shares, the business and affairs of the corporation shall be 
managed and all corporate powers shall be exercised by or under the direction 
of the board of directors.

     3.2  NUMBER OF DIRECTORS

     The board of directors shall consist of eight (8) members.  The number 
of directors may be changed by an amendment to this bylaw, duly adopted by 
the board of directors or by the stockholders, or by a duly adopted amendment 
to the certificate of incorporation.

     3.3  ELECTION AND TERM OF OFFICE OF DIRECTORS

     Except as provided in Section 3.4 of these bylaws, directors shall be 
elected at each annual meeting of stockholders to hold office until the next 
annual meeting. Each director, including a director elected or appointed to 
fill a vacancy, shall hold office until the expiration of the term for which 
elected and until a successor has been elected and qualified.

                                       -7-

<PAGE>

     3.4  RESIGNATION AND VACANCIES

     Any director may resign effective on giving written notice to the 
chairman of the board, the president, the secretary or the board of 
directors, unless the notice specifies a later time for that resignation to 
become effective.  If the resignation of a director is effective at a future 
time, the board of directors may elect a successor to take office when the 
resignation becomes effective.

     Vacancies in the board of directors may be filled by a majority of the 
remaining directors, even if less than a quorum, or by a sole remaining 
director; however, a vacancy created by the removal of a director by the vote 
of the stockholders or by court order may be filled only by the affirmative 
vote of a majority of the shares represented and voting at a duly held 
meeting at which a quorum is present (which shares voting affirmatively also 
constitute a majority of the required quorum).  Each director so elected 
shall hold office until the next annual meeting of the stockholders and until 
a successor has been elected and qualified.

     Unless otherwise provided in the certificate of incorporation or these 
bylaws:

               (i)  Vacancies and newly created directorships resulting from 
any increase in the authorized number of directors elected by all of the 
stockholders having the right to vote as a single class may be filled by a 
majority of the directors then in office, although less than a quorum, or by 
a sole remaining director.

               (ii) Whenever the holders of any class or classes of stock or 
series thereof are entitled to elect one or more directors by the provisions 
of the certificate of incorporation, vacancies and newly created 
directorships of such class or classes or series may be filled by a majority 
of the directors elected by such class or classes or series thereof then in 
office, or by a sole remaining director so elected.

     If at any time, by reason of death or resignation or other cause, the 
corporation should have no directors in office, then any officer or any 
stockholder or an executor, administrator, trustee or guardian of a 
stockholder, or other fiduciary entrusted with like responsibility for the 
person or estate of a stockholder, may call a special meeting of stockholders 
in accordance with the provisions of the certificate of incorporation or 
these bylaws, or may apply to the Court of Chancery for a decree summarily 
ordering an election as provided in Section 211 of the General Corporation 
Law of Delaware.

     If, at the time of filling any vacancy or any newly created 
directorship, the directors then in office constitute less than a majority of 
the whole board (as constituted immediately prior to any such increase), then 
the Court of Chancery may, upon application of any stockholder or 
stockholders holding at least ten (10) percent of the total number of the 
shares at the time outstanding having the right to vote for such directors, 
summarily order an election to be held to fill any such vacancies or newly 
created directorships, or to replace the directors chosen by the directors 
then in office as aforesaid, which election shall be governed by the 
provisions of Section 211 of the General Corporation Law of Delaware as far 
as applicable.

     3.5  REMOVAL OF DIRECTORS

     Unless otherwise restricted by statute, by the certificate of 
incorporation or by these bylaws, any director or the entire board of 
directors may be removed, with or without cause, by the holders of a majority 
of the shares then entitled to vote at an election of directors; provided, 
however, that, if and so long as stockholders of the corporation are entitled 
to cumulative voting, if less than the entire board is to be removed, no 
director may be removed without cause if the votes cast against his removal 
would be sufficient to elect him if then cumulatively voted at an election of 
the entire board of directors.

     3.6  PLACE OF MEETINGS; MEETINGS BY TELEPHONE

     Regular meetings of the board of directors may be held at any place 
within or outside the State of Delaware that has been designated from time to

regular meetings shall be held at the principal executive office of the 
corporation.  Special meetings of the board may be held at any place within 
or outside the State of Delaware that has been designated in the notice of 
the meeting or, if not stated in the notice or if there is no notice, at the 
principal executive office of the corporation.

     Any meeting of the board, regular or special, may be held by conference 
telephone or similar communication equipment, so long as all directors 
participating in the meeting can hear one another; and all such participating 
directors shall be deemed to be present in person at the meeting.

     3.7  FIRST MEETINGS

     The first meeting of each newly elected board of directors shall be held 
at such time and place as shall be fixed by the vote of the stockholders at 
the annual meeting.  In the event of the failure of the stockholders to fix 
the time or place of such first meeting of the newly elected board of 
directors, or in the event such meeting is not held at the time and place so 
fixed by the stockholders, the meeting may be held at such time and place as 
shall be specified in a notice given as hereinafter provided for special 
meetings of the board of directors, or as shall be specified in a written 
waiver signed by all of the directors.

     3.8  REGULAR MEETINGS

     Regular meetings of the board of directors may be held without notice at 
such time as shall from time to time be determined by the board of directors. 
If any regular meeting day shall fall on a legal holiday, then the meeting 
shall be held at the same time and place on the next succeeding full business 
day.

giving the notice has reason to believe will promptly communicate it to the 
director.  The notice need not specify the purpose or the place of the 
meeting, if the meeting is to be held at the principal executive office of 
the corporation.

     3.10 QUORUM

     A majority of the authorized number of directors shall constitute a 
quorum for the transaction of business, except to adjourn as provided in 
Section 3.12 of these bylaws.  Every act or decision done or made by a 
majority of the directors present at a duly held meeting at which a quorum is 
present shall be regarded as the act of the board of directors, subject to 
the provisions of the certificate of incorporation and applicable law.

     A meeting at which a quorum is initially present may continue to 
transact business notwithstanding the withdrawal of directors, if any action 
taken is approved by at least a majority of the quorum for that meeting.

     3.11 WAIVER OF NOTICE

     Notice of a meeting need not be given to any director (i) who signs a 
waiver of notice, whether before or after the meeting, or (ii) who attends 
the meeting other than for the express purposed of objecting at the beginning 
of the meeting to the transaction of any business because the meeting is not 
lawfully called or convened.  All such waivers shall be filed with the 
corporate records or made part of the minutes of the meeting.  A waiver of 
notice need not specify the purpose of any regular or special meeting of the 
board of directors.

     3.12 ADJOURNMENT

     A majority of the directors present, whether or not constituting a 
quorum, may adjourn any meeting of the board to another time and place.

     3.13 NOTICE OF ADJOURNMENT

     Notice of the time and place of holding an adjourned meeting of the 
board need not be given unless the meeting is adjourned for more than

not present at the time of the adjournment.

     3.14 BOARD ACTION BY WRITTEN CONSENT WITHOUT A MEETING

     Any action required or permitted to be taken by the board of directors 
may be taken without a meeting, provided that all members of the board 
individually or collectively consent in writing to that action.  Such action 
by written consent shall have the same force and effect as a unanimous vote 
of the board of directors. Such written consent and any counterparts thereof 
shall be filed with the minutes of the proceedings of the board of directors.

     3.15 FEES AND COMPENSATION OF DIRECTORS

     Directors and members of committees may receive such compensation, if 
any, for their services and such reimbursement of expenses as may be fixed or

other capacity as an officer, agent, employee or otherwise and receiving 
compensation for those services.

     3.16 APPROVAL OF LOANS TO OFFICERS

     The corporation may lend money to, or guarantee any obligation of, or 
otherwise assist any officer or other employee of the corporation or any of 
its subsidiaries, including any officer or employee who is a director of the

directors, such loan, guaranty or assistance may reasonably be expected to 
benefit the corporation.  The loan, guaranty or other assistance may be with 
or without interest and may be unsecured, or secured in such manner as the 
board of directors shall approve, including, without limitation, a pledge of

the corporation at common law or under any statute.

     3.17 SOLE DIRECTOR PROVIDED BY CERTIFICATE OF INCORPORATION

certificate of incorporation, then any reference herein to notices, waivers,

     4.1  COMMITTEES OF DIRECTORS

     The board of directors may, by resolution adopted by a majority of the 
authorized number of directors, designate one (1) or more committees, each 
consisting of two or more directors, to serve at the pleasure of the board.  
The board may designate one (1) or more directors as alternate members of any 
committee, who may replace any absent or disqualified member at any meeting 
of the committee.  The appointment of members or alternate members of a 
committee requires the vote of a majority of the authorized number of 
directors.  Any committee, to the extent provided in the resolution of the 
board, shall have and may exercise all the powers and authority of the board, 
but no such committee shall have the power or authority to (i) amend the 
certificate of incorporation (except that a committee may, to the extent 
authorized in the resolution or resolutions providing for the issuance of 
shares of stock adopted by the board of directors as provided in Section 
151(a) of the General Corporation Law of Delaware, fix the designations and 
any of the preferences or rights of such shares relating to dividends, 
redemption, dissolution, any distribution of assets of the corporation or the 
conversion into, or the exchange of such shares for, shares of any other 
class or classes or any other series of the same or any other class or 
classes of stock of the corporation), (ii) adopt an agreement of merger or 
consolidation under Sections 251 or 252 of the General Corporation Law of 
Delaware, (iii) recommend to the stockholders the sale, lease or exchange of 
all or substantially all of the corporation's property and assets, (iv) 
recommend to the stockholders a dissolution of the corporation or a 
revocation of a dissolution or (v) amend the bylaws of the corporation; and, 
unless the board resolution establishing the committee, the bylaws or the 
certificate of incorporation expressly so provide, no such committee shall 
have the power or authority to declare a dividend, to authorize the issuance 
of stock, or to adopt a certificate of ownership and merger pursuant to 
Section 253 of the General Corporation Law of Delaware.

Section 3.11 (waiver of notice), Section 3.12 (adjournment), Section 3.13
(notice of adjournment) and Section 3.14 (board action by written consent
without meeting), with such changes in the context of those bylaws as are
necessary to substitute the committee and its members for the board of directors
and its members; provided, however, that the time of regular meetings of
committees may be determined either by resolution of the board of directors or
by resolution of the committee, that special meetings of committees may also be
called by resolution of the board of directors, and that notice of special
meetings of committees shall also be given to all alternate members, who shall
have the right to attend all 

                                       -12-

directors, by any Corporate Officer upon whom such power of removal may be 
conferred by the board of directors.

     Any Corporate Officer may resign at any time by giving written notice to 
the corporation.  Any resignation shall take effect at the date of the 
receipt of that notice or at any later time specified in that notice; and, 
unless otherwise specified in that notice, the acceptance of the resignation 
shall not be necessary to make it effective.  Any resignation is without 
prejudice to the rights, if any, of the corporation under any contract to

                  INDEMNIFICATION OF DIRECTORS, OFFICERS, EMPLOYEES
                                   AND OTHER AGENTS

     6.1  INDEMNIFICATION OF DIRECTORS AND OFFICERS

     The corporation shall, to the maximum extent and in the manner permitted 
by the General Corporation Law of Delaware as the same now exists or may 
hereafter be amended, indemnify any person against expenses (including 
attorneys' fees), judgments, fines, and amounts paid in settlement actually 
and reasonably incurred in connection with any threatened, pending or 
completed action, suit, or proceeding in which such person was or is a party 
or is threatened to be made a party by reason of the fact that such person is 
or was a director or officer of the corporation.  For purposes of this 
Section 6.1, a "director" or "officer" of the corporation shall mean any 
person (i) who is or was a director or officer of the corporation, (ii) who 
is or was serving at the request of the corporation as a director or officer 
of another corporation, partnership, joint venture, trust or other 
enterprise, or (iii) who was a director or officer of a corporation which was 
a predecessor corporation of the corporation or of another enterprise at the 
request of such predecessor corporation.

     The corporation shall be required to indemnify a director or officer in 
connection with an action, suit, or proceeding (or part thereof) initiated by 
such director or officer only if the initiation of such action, suit, or 
proceeding (or part thereof) by the director or officer was authorized by the 
Board of Directors of the corporation.

     The corporation shall pay the expenses (including attorney's fees) 
incurred by a director or officer of the corporation entitled to 
indemnification hereunder in defending any action, suit or proceeding 
referred to in this Section 6.1 in advance of its final disposition; 
provided, however, that payment of expenses incurred by a director or officer 
of the corporation in advance of the final disposition of such action, suit 
or proceeding shall be made only upon receipt of an undertaking by the 
director or officer to repay all amounts advanced if it should ultimately be 
determined that the director of officer is not entitled to be indemnified 
under this Section 6.1 or otherwise.

     The rights conferred on any person by this Article shall not be 
exclusive of any other rights which such person may have or hereafter acquire 
under any statute, provision of the corporation's Certificate of 
Incorporation, these bylaws, agreement, vote of the stockholders or 
disinterested directors or otherwise.

     Any repeal or modification of the foregoing provisions of this Article 
shall not adversely affect any right or protection hereunder of any person in 
respect of any act or omission occurring prior to the time of such repeal or 
modification.

     6.2  INDEMNIFICATION OF OTHERS

     The corporation shall have the power, to the maximum extent and in the 
manner permitted by the General Corporation Law of Delaware as the same now

directors and officers) against expenses (including attorneys' fees), 
judgments, fines, and amounts paid in settlement actually and reasonably 
incurred in connection with any threatened, pending or completed action, 
suit, or proceeding, in which such person was or is a party or is threatened 
to be made a party by reason of the fact that such person is or was an 
employee or agent of the corporation.  For purposes of this Section 6.2, an 
"employee" or "agent" of the corporation (other than a director or officer) 
shall mean any person (i) who is or was an employee or agent of the 
corporation, (ii) who is or was serving at the request of the corporation as 
an employee or agent of another corporation, partnership, joint venture, 
trust or other enterprise, or (iii) who was an employee or agent of a 
corporation which was a predecessor corporation of the corporation or of 
another enterprise at the request of such predecessor corporation.

     6.3  INSURANCE

     The corporation may purchase and maintain insurance on behalf of any 
person who is or was a director, officer, employee or agent of the 
corporation, or is or was serving at the request of the corporation as a 
director, officer, employee or agent of another corporation, partnership, 
joint venture, trust or other enterprise against any liability asserted 
against him or her and incurred by him or her in any such capacity, or 
arising out of his or her status as such, whether or not the corporation 
would have the power to indemnify him or her against such liability under the 
provisions of the General Corporation Law of Delaware.

upon written demand under oath stating the purpose thereof, have the right
during the usual hours for business to inspect for any proper purpose the
corporation's stock ledger, a list of its stockholders, and its other books and
records and to make copies or extracts therefrom.  A proper purpose shall mean a
purpose reasonably related to such person's interest as a stockholder.  In every
instance where an attorney or other agent is 

                                       -18-

<PAGE>

the person who seeks the right to inspection, the demand under oath shall be 
accompanied by a power of attorney or such other writing that authorizes the 
attorney or other agent to so act on behalf of the stockholder. The demand 
under oath shall be directed to the corporation at its registered office in 
Delaware or at its principal place of business.

     7.2  INSPECTION BY DIRECTORS

     Any director shall have the right to examine (and to make copies of) the 
corporation's stock ledger, a list of its stockholders and its other books 
and records for a purpose reasonably related to his or her position as a 
director.

     7.3  ANNUAL STATEMENT TO STOCKHOLDERS

special meeting of the stockholders when called for by vote of the 
stockholders, a full and clear statement of the business and condition of the 
corporation.

     7.4  REPRESENTATION OF SHARES OF OTHER CORPORATIONS

     The chairman of the board, if any, the president, any vice president, 
the chief financial officer, the secretary or any assistant secretary of this 
corporation, or any other person authorized by the board of directors or the 
president or a vice president, is authorized to vote, represent and exercise 
on behalf of this corporation all rights incident to any and all shares of

this corporation.  The authority herein granted may be exercised either by 
such person directly or by any other person authorized to do so by proxy or 
power of attorney duly executed by such person having the authority.

     The original or a copy of these bylaws, as amended or otherwise altered 
to date, certified by the secretary, shall be kept at the corporation's

                                     ARTICLE VIII

                                   GENERAL MATTERS

     8.1  RECORD DATE FOR PURPOSES OTHER THAN NOTICE AND VOTING

     For purposes of determining the stockholders entitled to receive payment 
of any dividend or other distribution or allotment of any rights or the 
stockholders entitled to exercise any rights in respect of any change, 
conversion or exchange of stock, or for the purpose of any other lawful 
action, the board of directors may fix, in advance, a record date, which 
shall not precede the date upon which the resolution fixing the record date 
is adopted and which shall not be more than sixty (60) days before any such 
action.  In that case, only stockholders of record at the close of business 
on the date so fixed are entitled to receive the dividend, distribution or 
allotment of rights, or to exercise such rights, as the case may be, 
notwithstanding any transfer of any shares on the books of the corporation 
after the record date so fixed, except as otherwise provided by law.

     If the board of directors does not so fix a record date, then the record 
date for determining stockholders for any such purpose shall be at the close 
of business on the day on which the board of directors adopts the applicable 
resolution.

     8.2  CHECKS; DRAFTS; EVIDENCES OF INDEBTEDNESS

     From time to time, the board of directors shall determine by resolution 
which person or persons may sign or endorse all checks, drafts, other orders 
for payment of money, notes or other evidences of indebtedness that are 
issued in the name of or payable to the corporation, and only the persons so 
authorized shall sign or endorse those instruments.

     8.3  CORPORATE CONTRACTS AND INSTRUMENTS:  HOW EXECUTED

     The board of directors, except as otherwise provided in these bylaws, 
may authorize and empower any officer or officers, or agent or agents, to 
enter into any contract or execute any instrument in the name of and on 
behalf of the corporation; such power and authority may be general or 
confined to specific instances.  Unless so authorized or ratified by the 
board of directors or within the agency power of an officer, no officer, 
agent or employee shall have any power or authority to bind the corporation 
by any contract or engagement or to pledge its credit or to render it liable 
for any purpose or for any amount.

     8.4  STOCK CERTIFICATES; TRANSFER; PARTLY PAID SHARES

     The shares of the corporation shall be represented by certificates,
provided that the board of directors of the corporation may provide by
resolution or resolutions that some or all of any or all classes or series of
its stock shall be uncertificated shares.  Any such resolution shall not apply
to shares 

                                       -20-

<PAGE>

represented by a certificate until such certificate is surrendered to the 
corporation.  Notwithstanding the adoption of such a resolution by the board 
of directors, every holder of stock represented by certificates and, upon 
request, every holder of uncertificated shares, shall be entitled to have a 
certificate signed by, or in the name of the corporation by, the chairman or 
vice-chairman of the board of directors, or the president or vice-president, 
and by the treasurer or an assistant treasurer, or the secretary or an 
assistant secretary of such corporation representing the number of shares 
registered in certificate form.  Any or all of the signatures on the 
certificate may be a facsimile.  In case any officer, transfer agent or 
registrar who has signed or whose facsimile signature has been placed upon a 
certificate has ceased to be such officer, transfer agent or registrar before 
such certificate is issued, it may be issued by the corporation with the same 
effect as if he or she were such officer, transfer agent or registrar at the 
date of issue.

     Certificates for shares shall be of such form and device as the board of 
directors may designate and shall state the name of the record holder of the 
shares represented thereby; its number; date of issuance; the number of 
shares for which it is issued; a summary statement or reference to the 
powers, designations, preferences or other special rights of such stock and 
the qualifications, limitations or restrictions of such preferences and/or 
rights, if any; a statement or summary of liens, if any; a conspicuous notice 
of restrictions upon transfer or registration of transfer, if any; a 
statement as to any applicable voting trust agreement; if the shares be 
assessable, or, if assessments are collectible by personal action, a plain 
statement of such facts.

     Upon surrender to the secretary or transfer agent of the corporation of 
a certificate for shares duly endorsed or accompanied by proper evidence of 
succession, assignment or authority to transfer, it shall be the duty of the 
corporation to issue a new certificate to the person entitled thereto, cancel 
the old certificate and record the transaction upon its books.

     The corporation may issue the whole or any part of its shares as partly 
paid and subject to call for the remainder of the consideration to be paid 
therefor.  Upon the face or back of each stock certificate issued to 
represent any such partly paid shares, or upon the books and records of the 
corporation in the case of uncertificated partly paid shares, the total 
amount of the consideration to be paid therefor and the amount paid thereon 
shall be stated. Upon the declaration of any dividend on fully paid shares, 
the corporation shall declare a dividend upon partly paid shares of the same 
class, but only upon the basis of the percentage of the consideration 
actually paid thereon.

     8.5  SPECIAL DESIGNATION ON CERTIFICATES

     If the corporation is authorized to issue more than one class of stock or
more than one series of any class, then the powers, the designations, the
preferences and the relative, participating, optional or other special rights of
each class of stock or series thereof and the qualifications, limitations or
restrictions of such preferences and/or rights shall be set forth in full or
summarized on the face or back of the certificate that the 

                                       -21-

<PAGE>

corporation shall issue to represent such class or series of stock; provided, 
however, that, except as otherwise provided in Section 202 of the General 
Corporation Law of Delaware, in lieu of the foregoing requirements there may 
be set forth on the face or back of the certificate that the corporation 
shall issue to represent such class or series of stock a statement that the 
corporation will furnish without charge to each stockholder who so requests 
the powers, the designations, the preferences and the relative, 
participating, optional or other special rights of each class of stock or 
series thereof and the qualifications, limitations or restrictions of such 
preferences and/or rights.

     8.6  LOST CERTIFICATES

     Except as provided in this Section 8.6, no new certificates for shares 
shall be issued to replace a previously issued certificate unless the latter 
is surrendered to the corporation and cancelled at the same time.  The board 
of directors may, in case any share certificate or certificate for any other 
security is lost, stolen or destroyed, authorize the issuance of replacement 
certificates on such terms and conditions as the board may require; the board 
may require indemnification of the corporation secured by a bond or other 
adequate security sufficient to protect the corporation against any claim 
that may be made against it, including any expense or liability, on account 
of the alleged loss, theft or destruction of the certificate or the issuance 
of the replacement certificate.

     8.7  TRANSFER AGENTS AND REGISTRARS

     The board of directors may appoint one or more transfer agents or 
transfer clerks, and one or more registrars, each of which shall be an 
incorporated bank or trust company -- either domestic or foreign, who shall 
be appointed at such times and places as the requirements of the corporation 
may necessitate and the board of directors may designate.

     8.8  CONSTRUCTION; DEFINITIONS

     Unless the context requires otherwise, the general provisions, rules of 
construction and definitions in the General Corporation Law of Delaware shall 
govern the construction of these bylaws.  Without limiting the generality of 
this provision, as used in these bylaws, the singular number includes the 
plural, the plural number includes the singular, and the term "person" 
includes both an entity and a natural person.

                                      ARTICLE IX

                                      AMENDMENTS

     The original or other bylaws of the corporation may be adopted, amended 
or repealed by the stockholders entitled to vote or by the board of directors 
of the corporation.  The fact that such power has been so conferred upon the 
directors shall not divest the stockholders of the power, nor limit their 
power to adopt, amend or repeal bylaws.

                                       -22-

<PAGE>

     Whenever an amendment or new bylaw is adopted, it shall be copied in the 
book of bylaws with the original bylaws, in the appropriate place.  If any 
bylaw is repealed, the fact of repeal with the date of the meeting at which 
the repeal was enacted or the filing of the operative written consent(s) 
shall be stated in said book.

determines it to be desirable to qualify Options granted hereunder as 
"performance-based compensation" within the meaning of Section 162(m) of the 
Code, the Plan shall be administered by a Committee of two or more "outside 
directors" within the meaning of Section 162(m) of the Code.

                   (iii) RULE 16b-3.  To the extent desirable to qualify 
transactions hereunder as exempt under Rule 16b-3, the transactions 

                                       -3-

<PAGE>

contemplated hereunder shall be structured to satisfy the requirements for 
exemption under Rule 16b-3.

                    (iv) OTHER ADMINISTRATION.  Other than as provided above, 
the Plan shall be administered by (A) the Board or (B) a Committee, which 
committee shall be constituted to satisfy all applicable laws.

          (b)  POWERS OF THE BOARD.  Subject to the provisions of the Plan, 
the Board shall have the authority, in its discretion: (i) to grant Incentive 
Stock Options, Nonstatutory Stock Options or Stock Purchase Rights; (ii) to 
determine, upon review of relevant information and in accordance with Section 
7 of the Plan, the fair market value of the Common Stock; (iii) to determine 
the exercise price per share of Options or Stock Purchase Rights, to be 
granted, which exercise price shall be determined in accordance with Section 
7 of the Plan; (iv) to determine the Employees or Consultants to whom, and 
the time or times at which, Options or Stock Purchase Rights shall be granted 
and the number of shares to be represented by each Option or Stock Purchase 
Right; (v) to interpret the Plan; (vi) to prescribe, amend and rescind rules 
and regulations relating to the Plan; (vii) to determine the terms and 
provisions of each Option and Stock Purchase Right granted (which need not be 
identical) and, with the consent of the holder thereof, modify or amend each 
Option or Stock Purchase Right; (viii) to authorize any person to execute on 
behalf of the Company any instrument required to effectuate the grant of an 
Option or Stock Purchase Right previously granted by the Board; and (ix) to 
make all other determinations deemed necessary or advisable for the 
administration of the Plan.

          (c)  EFFECT OF BOARD'S DECISION.  All decisions, determinations and 
interpretations of the Board shall be final and binding on all Optionees, 
Purchasers and any other holders of any Options or Stock Purchase Rights 
granted under the Plan.

     5.   ELIGIBILITY.

          (a)  Options and Stock Purchase Rights may be granted to Employees 
and Consultants, provided that Incentive Stock Options may only be granted to 
Employees.  An Employee or Consultant who has been granted an Option or Stock 
Purchase Right may, if such 

                                       -4-

<PAGE>

Employee or Consultant is otherwise eligible, be granted additional Option(s) 
or Stock Purchase Right(s).

          (b)  No Incentive Stock Option may be granted to an Employee which, 
when aggregated with all other incentive stock options granted to such 
Employee by the Company or any Parent or Subsidiary, would result in Shares 
having an aggregate fair market value (determined for each Share as of the 
date of grant of the Option covering such Share) in excess of $100,000 
becoming first available for purchase upon exercise of one or more incentive 
stock options during any calendar year.

          (c)  Section 5(b) of the Plan shall apply only to an Incentive 
Stock Option evidenced by an "Incentive Stock Option Agreement" which sets 
forth the intention of the Company and the Optionee that such Option shall 
qualify as an incentive stock option.  Section 5(b) of the Plan shall not 
apply to any Option evidenced by a "Nonstatutory Stock Option Agreement" 
which sets forth the intention of the Company and the Optionee that such 
Option shall be a Nonstatutory Stock Option.

          (d)  The Plan shall not confer upon any Optionee or holder of a 
Stock Purchase Right any right with respect to continuation of employment by 
or the rendition of consulting services to the Company, nor shall it 
interfere in any way with his or her right or the Company's right to 
terminate his or her employment or services at any time, with or without 
cause.

     6.   TERM OF PLAN.  The Plan shall become effective upon the earlier to 
occur of its adoption by the Board of Directors or its approval by vote of 
the holders of a majority of the outstanding shares of the Company entitled 
to vote on the adoption of the Plan. It shall continue in effect for a term 
of ten (10) years unless sooner terminated under Section 14 of the Plan.

     7.   EXERCISE PRICE AND CONSIDERATION.

          (a)  The per Share exercise price for the Shares to be issued 
pursuant to exercise of an Option or Stock Purchase Right shall be such price 
as is determined by the Board, but shall be subject to the following:

                    (i)  In the case of an Incentive Stock Option

                                       -5-

<PAGE>

                         (A)  granted to an Employee who, at the time of the 
grant of such Incentive Stock Option, owns stock representing more than ten 
percent (10%) of the voting power of all classes of stock of the Company or 
any Parent or Subsidiary, the per Share exercise price shall be no less than 
110% of the fair market value per Share on the date of grant.

                         (B)  granted to any Employee, the per Share exercise 
price shall be no less than 100% of the fair market value per Share on the 
date of grant.

                    (ii) In the case of a Nonstatutory Stock Option

                         (A)  granted to a person who, at the time of the 
grant of such Option, owns stock representing more than ten percent (10%) of 
the voting power of all classes of stock of the Company or any Parent or 
Subsidiary, the per Share exercise price shall be no less than 110% of the 
fair market value per Share on the date of the grant.

                         (B)  granted to any person, the per Share exercise 
price shall be no less than 85% of the fair market value per Share on the 
date of grant.

                    (iii) In the case of a Stock Purchase Right

                         (A)  granted to any person who, at the time of the 
grant of such Stock Purchase Right, owns stock representing more than ten 
percent (10%) of the voting power of all classes of stock of the Company or 
any Parent or Subsidiary, the per Share exercise price shall be no less than 
110% of the fair market value per Share on the date of grant.

                         (B)  granted to any person, the per Share exercise 
price shall be no less than 85% of the fair market value per Share on the 
date of grant.

                    (iv) In the case of an Option or Stock Purchase Right 
granted on or after the effective date of registration of any class of equity 
security of the Company pursuant to Section 12 of the Exchange Act and prior 
to six months after the termination of such registration, the per Share 
exercise price shall be no less than 100% of the fair market value per Share 
on the date of grant.

                                       -6-

<PAGE>

          (b)  The fair market value shall be determined by the Board in its 
discretion; provided, however, that where there is a public market for the 
Common Stock, the fair market value per Share shall be the mean of the bid 
and asked prices (or the closing price per share if the Common Stock is 
listed on the National Association of Securities Dealers Automated Quotation 
("NASDAQ") National Market System of the Common Stock for the date of grant, 
as reported in the Wall Street Journal (or, if not so reported, as otherwise 
reported by the NASDAQ System) or, in the event the Common Stock is listed on 
a stock exchange, the fair market value per Share shall be the closing price 
on such exchange on the date of grant of the Option or Stock Purchase Right, 
as reported in the Wall Street Journal.

          (c)  The consideration to be paid for the Shares to be issued upon 
exercise of an Option or Stock Purchase Right, including the method of 
payment, shall be determined by the Board and may consist entirely of cash, 
check, promissory note, other Shares of Common Stock having a fair market 
value on the date of surrender equal to the aggregate exercise price of the 
Shares as to which said Option shall be exercised, or any combination of such 
methods of payment, or such other consideration and method of payment for the 
issuance of Shares to the extent permitted under Sections 408 and 409 of the 
California General Corporation Law.  In making its determination as to the 
type of consideration to accept, the Board shall consider if acceptance of 
such consideration may be reasonably expected to benefit the Company (Section 
315(b) of the California General Corporation Law).

     8.   OPTIONS.

          (a)  TERM OF OPTION.  The term of each Incentive Stock Option shall 
be ten (10) years from the date of grant thereof or such shorter term as may 
be provided in the Incentive Stock Option Agreement.  The term of each Option 
that is not an Incentive Stock Option shall be ten (10) years and one (1) day 
from the date of grant thereof or such shorter term as may be provided in the 
Stock Option Agreement.  However, in the case of an Option granted to an 
Employee who, at the time the Option is granted, owns stock representing more 
than ten percent (10%) of the voting power of all classes of stock of the 
Company or any Parent or Subsidiary, (i) if the Option is an Incentive Stock 
Option, the term of the Option shall be five (5) years from the date of grant 
thereof or such

                                       -7-

<PAGE>

shorter time as may be provided in the Stock Option Agreement, or (ii) if the 
Option is not an Incentive Stock Option, the term of the Option shall be five 
(5) years and one (1) day from the date of grant thereof or such other term 
as may be provided in the Stock Option Agreement.

          (b)  EXERCISE OF OPTION.

                    (i)  PROCEDURE FOR EXERCISE; RIGHTS AS A SHAREHOLDER. Any 
Option granted hereunder shall be exercisable at such times and under such 
conditions as determined by the Board, including performance criteria with 
respect to the Company and/or the Optionee, and as shall be permissible under 
the terms of the Plan; provided, however, that an Incentive Stock Option 
granted prior to January 1, 1987 (the "Sequential Option") shall not be 
exercisable while there is outstanding any Incentive Stock Option which was 
granted, before the granting of the Sequential Option, to the same Optionee 
to purchase stock of the Company, any Parent or Subsidiary, or any 
predecessor corporation of such corporations.  For purposes of this 
provision, an Incentive Stock Option shall be treated as outstanding until 
such Incentive Stock Option is exercised in full or expires by reason of 
lapse of time.

               An Option may not be exercised for a fraction of a Share.

               An Option shall be deemed to be exercised when written notice 
of such exercise has been given to the Company in accordance with the terms 
of the Option by the person entitled to exercise the Option and full payment 
for the Shares with respect to which the Option is exercised has been 
received by the Company.  Full payment may, as authorized by the Board, 
consist of any consideration and method of payment allowable under Section 7 
of the Plan. Until the issuance (as evidenced by the appropriate entry on the 
books of the Company or of a duly authorized transfer agent of the Company) 
of the stock certificate evidencing such Shares, no right to vote or receive 
dividends or any other rights as a shareholder shall exist with respect to 
the Optioned Stock, notwithstanding the exercise of the Option.  The Company 
shall issue (or cause to be issued) such stock certificate promptly upon 
exercise of the Option.  No adjustment will be made for a dividend or other 
right for which the record date is prior to the date the 

                                       -8-

<PAGE>

stock certificate is issued, except as provided in Section 11 of the Plan.

               Exercise of an Option in any manner shall result in a decrease 
in the number of Shares which thereafter may be available, both for purposes 
of the Plan and for sale under the Option, by the number of Shares as to 
which the Option is exercised.

                     (ii) TERMINATION OF STATUS AS AN EMPLOYEE OR CONSULTANT. 
In the event of termination of an Optionee's Continuous Status as an Employee 
or Consultant (as the case may be), such Optionee may, but only within thirty 
(30) days (or such other period of time not exceeding three (3) months in the 
case of an Incentive Stock Option or six (6) months in the case of a 
Nonstatutory Stock Option, as is determined by the Board, with such 
determination in the case of an Incentive Stock Option being made at the time 
of grant of the Option) after the date of such termination (but in no event 
later than the date of expiration of the term of such Option as set forth in 
the Option Agreement, exercise the Option to the extent that such Employee or 
Consultant was entitled to exercise it at the date of such termination.  To 
the extent that such Employee or Consultant was not entitled to exercise the 
Option at the date of such termination, or if such Employee or Consultant 
does not exercise such Option (which such Employee or Consultant was entitled 
to exercise) within the time specified herein, the Option shall terminate.

                    (iii) DISABILITY OF OPTIONEE.  Notwithstanding the 
provisions of Section 8(b)(ii) above, in the event of termination of an 
Optionee's Continuous Status as an Employee or Consultant as a result of such 
Employee's or Consultant's total and permanent disability (as defined in 
Section 22(e)(3) of the Code), such Employee or Consultant may, but only 
within six (6) months (or such other period of time not exceeding twelve (12) 
months as is determined by the Board, with such determination in the case of 
an Incentive Stock Option being made at the time of grant of the Option) from 
the date of such termination (but in no event later than the date of 
expiration of the term of such Option as set forth in the Option Agreement), 
exercise the Option to the extent such Employee or Consultant was entitled to 
exercise it at the date of such termination.  To the extent that such 
Employee or Consultant was not entitled to exercise the Option at the date of 
termination, or if such Employee or Consultant does not exercise such Option 

                                       -9-

<PAGE>

(which such Employee or Consultant was entitled to exercise) within the time 
specified herein, the Option shall terminate.

                    (iv) DEATH OF OPTIONEE.  In the event of the death of an 
Optionee:

                     (i) during the term of the Option who is at the time of his
          or her death an Employee or Consultant of the Company and who shall
          have been in Continuous Status as an Employee or Consultant since the
          date of grant of the Option, the Option may be exercised, at any time
          within six (6) months (or such other period of time as is determined
          by the Board at the time of grant of the Option) following the date of
          death (but in no event later than the date of expiration of the term
          of such Option as set forth in the Option Agreement), by the
          Optionee's estate or by a person who acquired the right to exercise
          the Option by bequest or inheritance, but only to the extent of the
          right to exercise that would have accrued had the Optionee continued
          living and remained in Continuous Status as an Employee or Consultant
          six (6) months (or such other period of time as is determined by the
          Board at the time of grant of the Option) after the date of death,
          subject to the limitation set forth in Section 5(b); or

                    (ii) within thirty (30) days (or such other period of time
          not exceeding three (3) months as is determined by the Board, with
          such determination in the case of an Incentive Stock Option being made
          at the time of grant of the Option) after the termination of
          Continuous Status as an Employee or Consultant, the Option may be
          exercised, at any time within six (6) months (or such other period of
          time as is determined by the Board at the time of grant of the Option)
          following the date of death (but in no event later than the date of
          expiration of the term of such Option as set forth in the Option
          Agreement), by the Optionee's estate or by a person who acquired the
          right to exercise the Option by bequest or inheritance, but only to
          the extent of the right to exercise that had accrued at the date of
          termination.

     9.   STOCK PURCHASE RIGHTS.

          (a)  RIGHTS TO PURCHASE.  After the Board of Directors determines 
that it will offer an Employee or Consultant a Stock Purchase Right, it shall 
deliver to the offeree a stock purchase agreement or stock bonus agreement, 
as the case may be, setting forth the terms, conditions and restrictions 
relating to the offer, including the number of Shares which such person shall 
be entitled to purchase, and the time within which such person must accept 
such offer, which shall in no event exceed six (6) months from the date upon 
which the Board of Directors or its Committee made the determination to grant 
the Stock Purchase Right.  The offer shall be accepted by execution of a 
stock purchase agreement or stock bonus agreement in the form determined by 
the Board of Directors.

          (b)  ISSUANCE OF SHARES.  Forthwith after payment therefor, the 
Shares purchased shall be duly issued; provided, however, that the Board may 
require that the Purchaser make adequate provision for any Federal and State 
withholding obligations of the Company as a condition to the Purchaser 
purchasing such Shares.

          (c)  REPURCHASE OPTION.  Unless the Board determines otherwise, the 
stock purchase agreement or stock bonus agreement shall grant the Company a 
repurchase option exercisable upon the voluntary or involuntary termination 
of the Purchaser's employment with the Company for any reason (including 
death or disability). If the Board so determines, the purchase price for 
shares repurchased may be paid by cancellation of any indebtedness of the 
Purchaser to the Company.  The repurchase option shall lapse at such rate as 
the Board may determine.

          (d)  OTHER PROVISIONS.  The stock purchase agreement or stock bonus 
agreement shall contain such other terms, provisions and conditions not 
inconsistent with the Plan as may be determined by the Board of Directors.

     10.  NON-TRANSFERABILITY OF OPTIONS AND STOCK PURCHASE RIGHTS. The 
Options and Stock Purchase Rights may not be sold, pledged, assigned, 
hypothecated, transferred, or disposed of in any manner other than by will or 
by the laws of descent or distribution and may be exercised, during the 
lifetime of the Optionee or Purchaser, only by the Optionee or Purchaser.

                                       -11-

<PAGE>

     11.  ADJUSTMENTS UPON CHANGES IN CAPITALIZATION OR MERGER. Subject to 
any required action by the shareholders of the Company, the number of shares 
of Common Stock covered by each outstanding Option and Stock Purchase Right, 
and the number of shares of Common Stock which have been authorized for 
issuance under the Plan but as to which no Options or Stock Purchase Rights 
have yet been granted or which have been returned to the Plan upon 
cancellation or expiration of an Option or Stock Purchase Right, or 
repurchase of Shares from a Purchaser upon termination of employment, as well 
as the price per share of Common Stock covered by each such outstanding 
Option or Stock Purchase Right, shall be proportionately adjusted for any 
increase or decrease in the number of issued shares of Common Stock resulting 
from a stock split, reverse stock split, stock dividend, combination or 
reclassification of the Common Stock of the Company or the payment of a stock 
dividend with respect to the Common Stock or any other increase or decrease 
in the number of issued shares of Common Stock effected without receipt of 
consideration by the Company; provided, however, that conversion of any 
convertible securities of the Company shall not be deemed to have been 
"effected without receipt of consideration."  Such adjustment shall be made 
by the Board, whose determination in that respect shall be final, binding and 
conclusive.  Except as expressly provided herein, no issuance by the Company 
of shares of stock of any class, or securities convertible into shares of 
stock of any class, shall affect, and no adjustment by reason thereof shall 
be made with respect to, the number or price of shares of Common Stock 
subject to an Option or Stock Purchase Right.

          In the event of the proposed dissolution or liquidation of the 
Company, the Board shall notify the Optionee at least fifteen (15) days prior 
to such proposed action.  To the extent it has not been previously exercised, 
the Option will terminate immediately prior to the consummation of such 
proposed action.  In the event of a merger of the Company with or into 
another corporation, the Option shall be assumed or an equivalent option 
shall be substituted by such successor corporation.

     12.  TIME OF GRANT.  The date of grant of an Option or Stock Purchase 
Right shall, for all purposes, be the date on which the Board makes the 
determination granting such Option or Stock Purchase Right.  Notice of the 
determination shall be given to each Employee or Consultant to whom an Option 
or Stock Purchase Right is so granted within a reasonable time after the date 
of such grant.

     13.  AMENDMENT AND TERMINATION OF THE PLAN.

          (a)  AMENDMENT AND TERMINATION.  The Board may amend or terminate 
the Plan from time to time in such respects as the Board may deem advisable; 
provided that, the following revisions or amendments shall require approval 
of the shareholders of the Company in the manner described in Section 17 of 
the Plan:

              (i)   any increase in the number of Shares subject to the Plan,
          other than in connection with an adjustment under Section 11 of the
          Plan;

             (ii)   any change in the designation of the class of persons
          eligible to be granted Options and Stock Purchase Rights; or

            (iii)   if the Company has a class of equity securities registered
          under Section 12 of the Exchange Act at the time of such revision or
          amendment, any material increase in the benefits accruing to
          participants under the Plan.

          (b)  SHAREHOLDER APPROVAL.  If any amendment requiring shareholder 
approval under Section 13(a) of the Plan is made subsequent to the first 
registration of any class of equity securities by the Company under Section 
12 of the Exchange Act, such shareholder approval shall be solicited as 
described in Section 17 of the Plan.

          (c)  EFFECT OF AMENDMENT OR TERMINATION.  Any such amendment or 
termination of the Plan shall not affect Options or Stock Purchase Rights 
already granted and such Options or Stock Purchase Rights shall remain in 
full force and effect as if this Plan had not been amended or terminated, 
unless mutually agreed otherwise between the Optionee or Purchaser (as the 
case may be) and the Board, which agreement must be in writing and signed by 
the Optionee or Purchaser (as the case may be) and the Company.

     14.  CONDITIONS UPON ISSUANCE OF SHARES.  Shares shall not be issued 
pursuant to the exercise of an Option or Stock Purchase Rights unless the 
exercise of such Option or Stock Purchase Rights and the issuance and 
delivery of such Shares pursuant thereto shall comply with all relevant 
provisions of law, including, without 

                                       -13-

<PAGE>

limitation, the Securities Act of 1933, as amended, the Exchange Act, the 
rules and regulations promulgated thereunder, and the requirements of any 
stock exchange upon which the Shares may then be listed, and shall be further 
subject to the approval of counsel for the Company with respect to such 
compliance.

          As a condition to the exercise of an Option or Stock Purchase 
Rights, the Company may require the person exercising such Option or Stock 
Purchase Rights to represent and warrant at the time of any such exercise 
that the Shares are being purchased only for investment and without any 
present intention to sell or distribute such Shares if, in the opinion of 
counsel for the Company, such a representation is required by any of the 
aforementioned relevant provisions of law.

     15.  RESERVATION OF SHARES.  The Company, during the term of this Plan, 
will at all times reserve and keep available such number of Shares as shall 
be sufficient to satisfy the requirements of the Plan.

          The inability of the Company to obtain authority from any 
regulatory body having jurisdiction, which authority is deemed by the 
Company's counsel to be necessary to the lawful issuance and sale of any 
Shares hereunder, shall relieve the Company of any liability in respect of 
the failure to issue or sell such Shares as to which such requisite authority 
shall not have been obtained.

     16.  OPTION, STOCK PURCHASE AND STOCK BONUS AGREEMENTS.  Options shall 
be evidenced by written option agreements in such form as the Board shall 
approve. Upon the exercise of Stock Purchase Rights, the Purchaser shall sign 
a stock purchase agreement or stock bonus agreement in such form as the Board 
shall approve.

     17.  SHAREHOLDER APPROVAL.

          (a)  Continuance of the Plan shall be subject to approval by the 
shareholders of the Company within twelve (12) months before or after the 
date the Plan is adopted.  If such shareholder approval is obtained at a duly 
held shareholders' meeting, it must be obtained by the affirmative vote of 
the holders of a majority of the outstanding shares of the Company, or if 
such shareholder approval is obtained by written consent, it must be obtained 
by the

                                       -14-

<PAGE>

unanimous written consent of all shareholders of the Company; provided, 
however, that approval at a meeting or by written consent may be obtained by 
a lesser degree of shareholder approval, if the Board determines, in its 
discretion after consultation with the Company's legal counsel, that such a 
lesser degree of shareholder approval will comply with all applicable laws 
and will not adversely affect the qualification of the Plan under Section 
422A of the Code.

          (b)  If and in the event that the Company registers any class of 
equity securities pursuant to Section 12 of the Exchange Act, any required 
approval of the shareholders of the Company obtained after such registration 
shall be solicited substantially in accordance with Section 14(a) of the 
Exchange Act and the rules and regulations promulgated thereunder.

          (c)  If any required approval by the shareholders of the Plan 
itself or of any amendment thereto is solicited at any time otherwise than in 
the manner described in Section 17(b) hereof, then the Company shall, at or 
prior to the first annual meeting of shareholders held subsequent to the 
later of (1) the first registration of any class of equity securities of the 
Company under Section 12 of the Exchange Act or (2) the granting of an Option 
hereunder to an officer or director after such registration, do the following:

     Options granted under the Plan may be Incentive Stock Options or

Code, the Plan shall be administered by a Committee of two or more "outside 
directors" within the meaning of Section 162(m) of the Code.

<PAGE>

               (iv) OTHER ADMINISTRATION.  Other than as provided above, the 
Plan shall be administered by (A) the Board or (B) a Committee, which 
committee shall be constituted to satisfy Applicable Laws. 

          (b)  POWERS OF THE ADMINISTRATOR.  Subject to the provisions of the 
Plan, and in the case of a Committee, subject to the specific duties 
delegated by the Board to such Committee, the Administrator shall have the 
authority, in its discretion:

               (i)       to determine the Fair Market Value;

               (ii)      to select the Service Providers to whom Options and 
Stock Purchase Rights may be granted hereunder;

               (iii)     to determine the number of shares of Common Stock to 
be covered by each Option and Stock Purchase Right granted hereunder;

               (iv)      to approve forms of agreement for use under the Plan;

               (v)       to determine the terms and conditions, not 
inconsistent with the terms of the Plan, of any Option or Stock Purchase 
Right granted hereunder.  Such terms and conditions include, but are not 
limited to, the exercise price, the time or times when Options or Stock 
Purchase Rights may be exercised (which may be based on performance 
criteria), any vesting acceleration or waiver of forfeiture restrictions, and 
any restriction or limitation regarding any Option or Stock Purchase Right or 
the shares of Common Stock relating thereto, based in each case on such 
factors as the Administrator, in its sole discretion, shall determine;

               (vi)      to reduce the exercise price of any Option or Stock 
Purchase Right to the then current Fair Market Value if the Fair Market Value 
of the Common Stock covered by such Option or Stock Purchase Right shall have 
declined since the date the Option or Stock Purchase Right was granted;

               (vii)     to institute an Option Exchange Program;

               (viii)    to construe and interpret the terms of the Plan and 
awards granted pursuant to the Plan;

               (ix)      to prescribe, amend and rescind rules and 
regulations relating to the Plan, including rules and regulations relating to 
sub-plans established for the purpose of qualifying for preferred tax 
treatment under foreign tax laws;

                                       -5-

<PAGE>

               (x)       to modify or amend each Option or Stock Purchase 
Right (subject to Section 15(c) of the Plan), including the discretionary 
authority to extend the post-termination exercisability period of Options 
longer than is otherwise provided for in the Plan;

               (xi)      to allow Optionees to satisfy withholding tax 
obligations by electing to have the Company withhold from the Shares to be 
issued upon exercise of an Option or Stock Purchase Right that number of 
Shares having a Fair Market Value equal to the amount required to be 
withheld.  The Fair Market Value of the Shares to be withheld shall be 
determined on the date that the amount of tax to be withheld is to be 
determined.  All elections by an Optionee to have Shares withheld for this 
purpose shall be made in such form and under such conditions as the 
Administrator may deem necessary or advisable;

               (xii)     to authorize any person to execute on behalf of the 
Company any instrument required to effect the grant of an Option or Stock 
Purchase Right previously granted by the Administrator;

               (xiii)    to make all other determinations deemed necessary or 
advisable for administering the Plan.

          (c)  EFFECT OF ADMINISTRATOR'S DECISION.  The Administrator's 
decisions, determinations and interpretations shall be final and binding on 
all Optionees and any other holders of Options or Stock Purchase Rights.

     5.   ELIGIBILITY.  Nonstatutory Stock Options and Stock Purchase Rights 
may be granted to Service Providers.  Incentive Stock Options may be granted 
only to Employees.

     6.   LIMITATIONS.

          (a)  Each Option shall be designated in the Option Agreement as 
either an Incentive Stock Option or a Nonstatutory Stock Option.  However, 
notwithstanding such designation, to the extent that the aggregate Fair 
Market Value of the Shares with respect to which Incentive Stock Options are 
exercisable for the first time by the Optionee during any calendar year 
(under all plans of the Company and any Parent or Subsidiary) exceeds 
$100,000, such Options shall be treated as Nonstatutory Stock Options.  For 
purposes of this Section 6(a), Incentive Stock Options shall be taken into 
account in the order in which they were granted.  The Fair Market Value of 
the Shares shall be determined as of the time the Option with respect to such 
Shares is granted.

          (b)  Neither the Plan nor any Option or Stock Purchase Right shall 
confer upon an Optionee any right with respect to continuing the Optionee's 
relationship as a Service Provider with the Company, nor shall they interfere 
in any way with the Optionee's right or the Company's right to terminate such 
relationship at any time, with or without cause.

                                       -6-

<PAGE>

          (c)  The following limitations shall apply to grants of Options:

               (i)   No Service Provider shall be granted, in any fiscal year 
of the Company, Options to purchase more than 500,000 Shares.

               (ii)  In connection with his or her initial service, a Service 
Provider may be granted Options to purchase up to an additional 
500,000 Shares which shall not count against the limit set forth in 
subsection (i) above.

               (iii) The foregoing limitations shall be adjusted 
proportionately in connection with any change in the Company's capitalization 
as described in Section 13. 

               (iv)  If an Option is cancelled in the same fiscal year of the 
Company in which it was granted (other than in connection with a transaction 
described in Section 13), the cancelled Option will be counted against the 
limits set forth in subsections (i) and (ii) above.  For this purpose, if the 
exercise price of an Option is reduced, the transaction will be treated as a 
cancellation of the Option and the grant of a new Option.

     7.   TERM OF PLAN.  Subject to Section 19 of the Plan, the Plan shall 
become effective upon its adoption by the Board.  It shall continue in effect 
for a term of ten (10) years unless terminated earlier under Section 15 of 
the Plan.

     8.   TERM OF OPTION.  The term of each Option shall be stated in the 
Option Agreement.  In the case of an Incentive Stock Option, the term shall 
be ten (10) years from the date of grant or such shorter term as may be 
provided in the Option Agreement.  Moreover, in the case of an Incentive 
Stock Option granted to an Optionee who, at the time the Incentive Stock 
Option is granted, owns stock representing more than ten percent (10%) of the 
total combined voting power of all classes of stock of the Company or any 
Parent or Subsidiary, the term of the Incentive Stock Option shall be five 
(5) years from the date of grant or such shorter term as may be provided in 
the Option Agreement.

     9.   OPTION EXERCISE PRICE AND CONSIDERATION.

          (a)  EXERCISE PRICE.  The per share exercise price for the Shares 
to be issued pursuant to exercise of an Option shall be determined by the 
Administrator, subject to the following:

               (i)  In the case of an Incentive Stock Option

                    (A)  granted to an Employee who, at the time the 
Incentive Stock Option is granted, owns stock representing more than ten 
percent (10%) of the voting power of all classes of stock of the Company or 
any Parent or Subsidiary, the per Share exercise price shall be no less than 
110% of the Fair Market Value per Share on the date of grant.

                                       -7-

<PAGE>

                    (B)  granted to any Employee other than an Employee 
described in paragraph (A) immediately above, the per Share exercise price 
shall be no less than 100% of the Fair Market Value per Share on the date of 
grant.

               (ii) In the case of a Nonstatutory Stock Option, the per Share 
exercise price shall be determined by the Administrator.  In the case of a 
Nonstatutory Stock Option intended to qualify as "performance-based 
compensation" within the meaning of Section 162(m) of the Code, the per Share 
exercise price shall be no less than 100% of the Fair Market Value per Share 
on the date of grant.

               (iii) Notwithstanding the foregoing, Options may be granted 
with a per Share exercise price of less than 100% of the Fair Market Value 
per Share on the date of grant pursuant to a merger or other corporate 
transaction.

          (b)  WAITING PERIOD AND EXERCISE DATES.  At the time an Option is 
granted, the Administrator shall fix the period within which the Option may 
be exercised and shall determine any conditions which must be satisfied 
before the Option may be exercised. 

          (c)  FORM OF CONSIDERATION.  The Administrator shall determine the 
acceptable form of consideration for exercising an Option, including the 
method of payment.  In the case of an Incentive Stock Option, the 
Administrator shall determine the acceptable form of consideration at the 
time of grant.  Such consideration may consist entirely of:

               (i)     cash;

               (ii)    check;

               (iii)   promissory note;

               (iv)    other Shares which (A) in the case of Shares acquired 
upon exercise of an option, have been owned by the Optionee for more than six 
months on the date of surrender, and (B) have a Fair Market Value on the date 
of surrender equal to the aggregate exercise price of the Shares as to which 
said Option shall be exercised;

               (v)     consideration received by the Company under a cashless 
exercise program implemented by the Company in connection with the Plan;

               (vi)    a reduction in the amount of any Company liability to 
the Optionee, including any liability attributable to the Optionee's 
participation in any Company-sponsored deferred compensation program or 
arrangement;

               (vii)   any combination of the foregoing methods of payment; or

                                       -8-

<PAGE>

               (viii)  such other consideration and method of payment for the 
issuance of Shares to the extent permitted by Applicable Laws.

     10.  EXERCISE OF OPTION.

          (a)  PROCEDURE FOR EXERCISE; RIGHTS AS A SHAREHOLDER. Any Option 
granted hereunder shall be exercisable according to the terms of the Plan and 
at such times and under such conditions as determined by the Administrator 
and set forth in the Option Agreement.  Unless the Administrator provides 
otherwise, vesting of Options granted hereunder shall be tolled during any 
unpaid leave of absence.  An Option may not be exercised for a fraction of a 
Share.

               An Option shall be deemed exercised when the Company receives: 
(i) written or electronic notice of exercise (in accordance with the Option 
Agreement) from the person entitled to exercise the Option, and (ii) full 
payment for the Shares with respect to which the Option is exercised.  Full 
payment may consist of any consideration and method of payment authorized by 
the Administrator and permitted by the Option Agreement and the Plan.  Shares 
issued upon exercise of an Option shall be issued in the name of the Optionee 
or, if requested by the Optionee, in the name of the Optionee and his or her 
spouse. Until the Shares are issued (as evidenced by the appropriate entry on 
the books of the Company or of a duly authorized transfer agent of the 
Company), no right to vote or receive dividends or any other rights as a 
shareholder shall exist with respect to the Optioned Stock, notwithstanding 
the exercise of the Option. The Company shall issue (or cause to be issued) 
such Shares promptly after the Option is exercised.  No adjustment will be 
made for a dividend or other right for which the record date is prior to the 
date the Shares are issued, except as provided in Section 13 of the Plan.

               Exercising an Option in any manner shall decrease the number 
of Shares thereafter available, both for purposes of the Plan and for sale 
under the Option, by the number of Shares as to which the Option is exercised.

          (b)  TERMINATION OF RELATIONSHIP AS A SERVICE PROVIDER.  If an 
Optionee ceases to be a Service Provider, other than upon the Optionee's 
death or Disability, the Optionee may exercise his or her Option within such 
period of time as is specified in the Option Agreement to the extent that the 
Option is vested on the date of termination (but in no event later than the 
expiration of the term of such Option as set forth in the Option Agreement).  
In the absence of a specified time in the Option Agreement, the Option shall 
remain exercisable for three (3) months following the Optionee's termination. 
 If, on the date of termination, the Optionee is not vested as to his or her 
entire Option, the Shares covered by the unvested portion of the Option shall 
revert to the Plan. If, after termination, the Optionee does not exercise his 
or her Option within the time specified by the Administrator, the Option 
shall terminate, and the Shares covered by such Option shall revert to the 
Plan.

                                       -9-

<PAGE>

          (c)  DISABILITY OF OPTIONEE.  If an Optionee ceases to be a Service 
Provider as a result of the Optionee's Disability, the Optionee may exercise 
his or her Option within such period of time as is specified in the Option 
Agreement to the extent the Option is vested on the date of termination (but 
in no event later than the expiration of the term of such Option as set forth 
in the Option Agreement).  In the absence of a specified time in the Option 
Agreement, the Option shall remain exercisable for twelve (12) months 
following the Optionee's termination.  If, on the date of termination, the 
Optionee is not vested as to his or her entire Option, the Shares covered by 
the unvested portion of the Option shall revert to the Plan.  If, after 
termination, the Optionee does not exercise his or her Option within the time 
specified herein, the Option shall terminate, and the Shares covered by such 
Option shall revert to the Plan.

          (d)  DEATH OF OPTIONEE.  If an Optionee dies while a Service 
Provider, the Option may be exercised within such period of time as is 
specified in the Option Agreement (but in no event later than the expiration 
of the term of such Option as set forth in the Notice of Grant), by the 
Optionee's estate or by a person who acquires the right to exercise the 
Option by bequest or inheritance, but only to the extent that the Option is 
vested on the date of death.  In the absence of a specified time in the 
Option Agreement, the Option shall remain exercisable for twelve (12) months 
following the Optionee's termination.  If, at the time of death, the Optionee 
is not vested as to his or her entire Option, the Shares covered by the 
unvested portion of the Option shall immediately revert to the Plan.  The 
Option may be exercised by the executor or administrator of the Optionee's 
estate or, if none, by the person(s) entitled to exercise the Option under 
the Optionee's will or the laws of descent or distribution.  If the Option is 
not so exercised within the time specified herein, the Option shall 
terminate, and the Shares covered by such Option shall revert to the Plan.

          (e)  BUYOUT PROVISIONS.  The Administrator may at any time offer to 
buy out for a payment in cash or Shares, an Option previously granted based 
on such terms and conditions as the Administrator shall establish and 
communicate to the Optionee at the time that such offer is made.

     11.  STOCK PURCHASE RIGHTS.

          (a)  RIGHTS TO PURCHASE.  Stock Purchase Rights may be issued 
either alone, in addition to, or in tandem with other awards granted under 
the Plan and/or cash awards made outside of the Plan.  After the 
Administrator determines that it will offer Stock Purchase Rights under the 
Plan, it shall advise the offeree in writing or electronically, by means of a 
Notice of Grant, of the terms, conditions and restrictions related to the 
offer, including the number of Shares that the offeree shall be entitled to 
purchase, the price to be paid, and the time within which the offeree must 
accept such offer.  The offer shall be accepted by execution of a Restricted 
Stock Purchase Agreement in the form determined by the Administrator.

          (b)  REPURCHASE OPTION.  Unless the Administrator determines 
otherwise, the Restricted Stock Purchase Agreement shall grant the Company a 
repurchase option exercisable upon the voluntary or involuntary termination 
of the purchaser's service with the Company for any reason 

                                       -10-

<PAGE>

(including death or Disability).  The purchase price for Shares repurchased 
pursuant to the Restricted Stock purchase agreement shall be the original 
price paid by the purchaser and may be paid by cancellation of any 
indebtedness of the purchaser to the Company.  The repurchase option shall 
lapse at a rate determined by the Administrator.

          (c)  OTHER PROVISIONS.  The Restricted Stock Purchase Agreement 
shall contain such other terms, provisions and conditions not inconsistent 
with the Plan as may be determined by the Administrator in its sole 
discretion. 

          (d)  RIGHTS AS A SHAREHOLDER.  Once the Stock Purchase Right is 
exercised, the purchaser shall have the rights equivalent to those of a 
shareholder, and shall be a shareholder when his or her purchase is entered 
upon the records of the duly authorized transfer agent of the Company.  No 
adjustment will be made for a dividend or other right for which the record 
date is prior to the date the Stock Purchase Right is exercised, except as 
provided in Section 13 of the Plan.

     12.  NON-TRANSFERABILITY OF OPTIONS AND STOCK PURCHASE RIGHTS.  Unless 
determined otherwise by the Administrator, an Option or Stock Purchase Right 
may not be sold, pledged, assigned, hypothecated, transferred, or disposed of 
in any manner other than by will or by the laws of descent or distribution 
and may be exercised, during the lifetime of the Optionee, only by the 
Optionee.  If the Administrator makes an Option or Stock Purchase Right 
transferable, such Option or Stock Purchase Right shall contain such 
additional terms and conditions as the Administrator deems appropriate.

     13.  ADJUSTMENTS UPON CHANGES IN CAPITALIZATION, DISSOLUTION, MERGER OR  
          ASSET SALE. 
   
          (a)  CHANGES IN CAPITALIZATION.  Subject to any required action by 
the shareholders of the Company, the number of shares of Common Stock covered 
by each outstanding Option and Stock Purchase Right, and the number of shares 
of Common Stock which have been authorized for issuance under the Plan but as 
to which no Options or Stock Purchase Rights have yet been granted or which 
have been returned to the Plan upon cancellation or expiration of an Option 
or Stock Purchase Right, as well as the price per share of Common Stock 
covered by each such outstanding Option or Stock Purchase Right, shall be 
proportionately adjusted for any increase or decrease in the number of issued 
shares of Common Stock resulting from a stock split, reverse stock split, 
stock dividend, combination or reclassification of the Common Stock, or any 
other increase or decrease in the number of issued shares of Common Stock 
effected without receipt of consideration by the Company; provided, however, 
that conversion of any convertible securities of the Company shall not be 
deemed to have been "effected without receipt of consideration."  Such 
adjustment shall be made by the Board, whose determination in that respect 
shall be final, binding and conclusive. Except as expressly provided herein, 
no issuance by the Company of shares of stock of any class, or securities 
convertible into shares of stock of any class, shall affect, and no 
adjustment by reason thereof shall be made with respect to, the number or 
price of shares of Common Stock subject to an Option or Stock Purchase Right.

                                       -11-

<PAGE>

          (b)  DISSOLUTION OR LIQUIDATION.  In the event of the proposed 
dissolution or liquidation of the Company, the Administrator shall notify 
each Optionee as soon as practicable prior to the effective date of such 
proposed transaction.  The Administrator in its discretion may provide for an 
Optionee to have the right to exercise his or her Option until ten (10) days 
prior to such transaction as to all of the Optioned Stock covered thereby, 
including Shares as to which the Option would not otherwise be exercisable.  
In addition, the Administrator may provide that any Company repurchase option 
applicable to any Shares purchased upon exercise of an Option or Stock 
Purchase Right shall lapse as to all such Shares, provided the proposed 
dissolution or liquidation takes place at the time and in the manner 
contemplated.  To the extent it has not been previously exercised, an Option 
or Stock Purchase Right will terminate immediately prior to the consummation 
of such proposed action.

          (c)  MERGER OR ASSET SALE.  In the event of a merger of the Company 
with or into another corporation, or the sale of substantially all of the 
assets of the Company, each outstanding Option and Stock Purchase Right shall 
be assumed or an equivalent option or right substituted by the successor 
corporation or a Parent or Subsidiary of the successor corporation.  In the 
event that the successor corporation refuses to assume or substitute for the 
Option or Stock Purchase Right, the Optionee shall fully vest in and have the 
right to exercise the Option or Stock Purchase Right as to all of the 
Optioned Stock, including Shares as to which it would not otherwise be vested 
or exercisable.  If an Option or Stock Purchase Right becomes fully vested 
and exercisable in lieu of assumption or substitution in the event of a 
merger or sale of assets, the Administrator shall notify the Optionee in 
writing or electronically that the Option or Stock Purchase Right shall be 
fully vested and exercisable for a period of fifteen (15) days from the date 
of such notice, and the Option or Stock Purchase Right shall terminate upon 
the expiration of such period.  For the purposes of this paragraph, the 
Option or Stock Purchase Right shall be considered assumed if, following the 
merger or sale of assets, the option or right confers the right to purchase 
or receive, for each Share of Optioned Stock subject to the Option or Stock 
Purchase Right immediately prior to the merger or sale of assets, the 
consideration (whether stock, cash, or other securities or property) received 
in the merger or sale of assets by holders of Common Stock for each Share 
held on the effective date of the transaction (and if holders were offered a 
choice of consideration, the type of consideration chosen by the holders of a 
majority of the outstanding Shares); provided, however, that if such 
consideration received in the merger or sale of assets is not solely common 
stock of the successor corporation or its Parent, the Administrator may, with 
the consent of the successor corporation, provide for the consideration to be 
received upon the exercise of the Option or Stock Purchase Right, for each 
Share of Optioned Stock subject to the Option or Stock Purchase Right, to be 
solely common stock of the successor corporation or its Parent equal in fair 
market value to the per share consideration received by holders of Common 
Stock in the merger or sale of assets.

     14.  DATE OF GRANT.  The date of grant of an Option or Stock Purchase 
Right shall be, for all purposes, the date on which the Administrator makes 
the determination granting such Option or Stock Purchase Right, or such other 
later date as is determined by the Administrator.  Notice of the 

                                       -12-

<PAGE>

determination shall be provided to each Optionee within a reasonable time 
after the date of such grant.

     15.  AMENDMENT AND TERMINATION OF THE PLAN.

          (a)  AMENDMENT AND TERMINATION.  The Board may at any time amend, 
alter, suspend or terminate the Plan.  

          (b)  SHAREHOLDER APPROVAL.  The Company shall obtain shareholder 
approval of any Plan amendment to the extent necessary and desirable to 
comply with Applicable Laws. 

          (c)  EFFECT OF AMENDMENT OR TERMINATION.  No amendment, alteration, 
suspension or termination of the Plan shall impair the rights of any 
Optionee, unless mutually agreed otherwise between the Optionee and the 
Administrator, which agreement must be in writing and signed by the Optionee 
and the Company. Termination of the Plan shall not affect the Administrator's 
ability to exercise the powers granted to it hereunder with respect to 
options granted under the Plan prior to the date of such termination.

     16.  CONDITIONS UPON ISSUANCE OF SHARES.  

          (a)  LEGAL COMPLIANCE.  Shares shall not be issued pursuant to the 
exercise of an Option or Stock Purchase Right unless the exercise of such 
Option or Stock Purchase Right and the issuance and delivery of such Shares 
shall comply with Applicable Laws and shall be further subject to the 
approval of counsel for the Company with respect to such compliance.

          (b)  INVESTMENT REPRESENTATIONS.  As a condition to the exercise of 
an Option or Stock Purchase Right, the Company may require the person 
exercising such Option or Stock Purchase Right to represent and warrant at 
the time of any such exercise that the Shares are being purchased only for 
investment and without any present intention to sell or distribute such 
Shares if, in the opinion of counsel for the Company, such a representation 
is required.

     17.  INABILITY TO OBTAIN AUTHORITY.  The inability of the Company to 
obtain authority from any regulatory body having jurisdiction, which 
authority is deemed by the Company's counsel to be necessary to the lawful 
issuance and sale of any Shares hereunder, shall relieve the Company of any 
liability in respect of the failure to issue or sell such Shares as to which 
such requisite authority shall not have been obtained.

     18.  RESERVATION OF SHARES.  The Company, during the term of this Plan, 
will at all times reserve and keep available such number of Shares as shall 
be sufficient to satisfy the requirements of the Plan.

                                       -13-

<PAGE>

     19.  SHAREHOLDER APPROVAL.  The Plan shall be subject to approval by the 
shareholders of the Company within twelve (12) months after the date the Plan 
is adopted.  Such shareholder approval shall be obtained in the manner and to 
the degree required under Applicable Laws.

<PAGE>

     TERMINATION PERIOD:

     This Option may be exercised for _____ [days/months] after Optionee 
ceases to be a Service Provider.  Upon the death or Disability of the

II.  AGREEMENT

     1.   GRANT OF OPTION.  The Plan Administrator of the Company hereby 
grants to the Optionee named in the Notice of Grant attached as Part I of 
this Agreement (the "Optionee") an option (the "Option") to purchase the 
number of Shares, as set forth in the Notice of Grant, at the exercise price 
per share set forth in the Notice of Grant (the "Exercise Price"), subject to 
the terms and conditions of the Plan, which is incorporated herein by 
reference.  Subject to Section 15(c) of the Plan, in the event of a conflict 
between the terms and conditions of the Plan and the terms and conditions of 
this Option Agreement, the terms and conditions of the Plan shall prevail.

          If designated in the Notice of Grant as an Incentive Stock Option 
("ISO"), this Option is intended to qualify as an Incentive Stock Option 
under Section 422 of the Code.  However, if this Option is intended to be an 
Incentive Stock Option, to the extent that it exceeds the $100,000 rule of 
Code Section 422(d) it shall be treated as a Nonstatutory Stock Option 
("NSO").

     2.   EXERCISE OF OPTION.

          (a)  RIGHT TO EXERCISE.  This Option is exercisable during its term 
in accordance with the Vesting Schedule set out in the Notice of Grant and 
the applicable provisions of the Plan and this Option Agreement.

          (b)  METHOD OF EXERCISE.  This Option is exercisable by delivery of 
an exercise notice, in the form attached as Exhibit A (the "Exercise 
Notice"), which shall state the election to exercise the Option, the number 
of Shares in respect of which the Option is being exercised (the "Exercised 
Shares"), and such other representations and agreements as may be required by 
the Company pursuant to the provisions of the Plan.  The Exercise Notice 
shall be completed by the Optionee and delivered to [Title] of the Company.  
The Exercise Notice shall be accompanied by payment of the aggregate Exercise 
Price as to all Exercised Shares.  This Option shall be deemed to be 
exercised upon receipt by the Company of such fully executed Exercise Notice 
accompanied by such aggregate Exercise Price.

          No Shares shall be issued pursuant to the exercise of this Option 
unless such issuance and exercise complies with Applicable Laws.  Assuming 
such compliance, for income tax purposes the Exercised Shares shall be 
considered transferred to the Optionee on the date the Option is exercised 
with respect to such Exercised Shares.

                                       -2-

<PAGE>

     3.   METHOD OF PAYMENT.  Payment of the aggregate Exercise Price shall 
be by any of the following, or a combination thereof, at the election of the 
Optionee:

          (a)  cash; or

          (b)  check[; or

          (c)  consideration received by the Company under a cashless 
exercise program implemented by the Company in connection with the Plan][; or 

          (d)  surrender of other Shares which (i) in the case of Shares 
acquired upon exercise of an option, have been owned by the Optionee for more 
than six (6) months on the date of surrender, AND (ii) have a Fair Market 
Value on the date of surrender equal to the aggregate Exercise Price of the 
Exercised Shares][; or

          (e)  with the Administrator's consent, delivery of Optionee's 
promissory note (the "Note") in the form attached hereto as Exhibit C, in the 
amount of the aggregate Exercise Price of the Exercised Shares together with 
the execution and delivery by the Optionee of the Security Agreement attached 
hereto as Exhibit B.  The Note shall bear interest at the "applicable federal 
rate" prescribed under the Code and its regulations at time of purchase, and 
shall be secured by a pledge of the Shares purchased by the Note pursuant to 
the Security Agreement].

     4.   NON-TRANSFERABILITY OF OPTION.  This Option may not be transferred 
in any manner otherwise than by will or by the laws of descent or 
distribution and may be exercised during the lifetime of Optionee only by the 
Optionee.  The terms of the Plan and this Option Agreement shall be binding 
upon the executors, administrators, heirs, successors and assigns of the 
Optionee.

     5.   TERM OF OPTION.  This Option may be exercised only within the term 
set out in the Notice of Grant, and may be exercised during such term only in 
accordance with the Plan and the terms of this Option Agreement.

     6.   TAX CONSEQUENCES.  Some of the federal tax consequences relating to 
this Option, as of the date of this Option, are set forth below.  THIS 
SUMMARY IS NECESSARILY INCOMPLETE, AND THE TAX LAWS AND REGULATIONS ARE 
SUBJECT TO CHANGE.  THE OPTIONEE SHOULD CONSULT A TAX ADVISER BEFORE 
EXERCISING THIS OPTION OR DISPOSING OF THE SHARES.

          (a)  EXERCISING THE OPTION.

               (i)  NONSTATUTORY STOCK OPTION.  The Optionee may incur 
regular federal income tax liability upon exercise of a NSO.  The Optionee 
will be treated as having received compensation income (taxable at ordinary 
income tax rates) equal to the excess, if any, of the Fair 

                                       -3-

<PAGE>

Market Value of the Exercised Shares on the date of exercise over their 
aggregate Exercise Price.  If the Optionee is an Employee or a former 
Employee, the Company will be required to withhold from his or her 
compensation or collect from Optionee and pay to the applicable taxing 
authorities an amount in cash equal to a percentage of this compensation 
income at the time of exercise, and may refuse to honor the exercise and 
refuse to deliver Shares if such withholding amounts are not delivered at the 
time of exercise.

               (ii) INCENTIVE STOCK OPTION.  If this Option qualifies as an 
ISO, the Optionee will have no regular federal income tax liability upon its 
exercise, although the excess, if any, of the Fair Market Value of the 
Exercised Shares on the date of exercise over their aggregate Exercise Price 
will be treated as an adjustment to alternative minimum taxable income for 
federal tax purposes and may subject the Optionee to alternative minimum tax 
in the year of exercise.  In the event that the Optionee ceases to be an 
Employee but remains a Service Provider, any Incentive Stock Option of the 
Optionee that remains unexercised shall cease to qualify as an Incentive 
Stock Option and will be treated for tax purposes as a Nonstatutory Stock 
Option on the date three (3) months and one (1) day following such change of 
status.

          (b)  DISPOSITION OF SHARES.  

               (i)  NSO.  If the Optionee holds NSO Shares for at least one 
year, any gain realized on disposition of the Shares will be treated as 
long-term capital gain for federal income tax purposes.

               (ii) ISO.  If the Optionee holds ISO Shares for at least one 
year after exercise and two years after the grant date, any gain realized on 
disposition of the Shares will be treated as long-term capital gain for 
federal income tax purposes.  If the Optionee disposes of ISO Shares within 
one year after exercise or two years after the grant date, any gain realized 
on such disposition will be treated as compensation income (taxable at 
ordinary income rates) to the extent of the excess, if any, of the lesser of 
(A) the difference between the Fair Market Value of the Shares acquired on 
the date of exercise and the aggregate Exercise Price, or (B) the difference 
between the sale price of such Shares and the aggregate Exercise Price.  Any 
additional gain will be taxed as capital gain, short-term or long-term 
depending on the period that the ISO Shares were held.

          (c)  NOTICE OF DISQUALIFYING DISPOSITION OF ISO SHARES.  If the 
Optionee sells or otherwise disposes of any of the Shares acquired pursuant 
to an ISO on or before the later of (i) two years after the grant date, or 
(ii) one year after the exercise date, the Optionee shall immediately notify 
the Company in writing of such disposition.  The Optionee agrees that he or 
she may be subject to income tax withholding by the Company on the 
compensation income recognized from such early disposition of ISO Shares by 
payment in cash or out of the current earnings paid to the Optionee.

Company and Optionee with respect to the subject matter hereof, and may not

EARNED ONLY BY CONTINUING AS A SERVICE PROVIDER AT THE WILL OF THE COMPANY 
(AND NOT THROUGH THE ACT OF BEING HIRED, BEING GRANTED AN OPTION OR 
PURCHASING SHARES HEREUNDER).  OPTIONEE FURTHER ACKNOWLEDGES AND AGREES THAT 
THIS AGREEMENT, THE TRANSACTIONS CONTEMPLATED HEREUNDER AND THE VESTING 
SCHEDULE SET FORTH HEREIN DO NOT CONSTITUTE AN EXPRESS OR IMPLIED PROMISE OF 
CONTINUED ENGAGEMENT AS A SERVICE PROVIDER FOR THE VESTING PERIOD, FOR ANY 
PERIOD, OR AT ALL, AND SHALL NOT INTERFERE WITH OPTIONEE'S RIGHT OR THE 
COMPANY'S RIGHT TO TERMINATE OPTIONEE'S RELATIONSHIP AS A SERVICE PROVIDER AT 
ANY TIME, WITH OR WITHOUT CAUSE.

     By your signature and the signature of the Company's representative 
below, you and the Company agree that this Option is granted under and 
governed by the terms and conditions of the Plan and this Option Agreement.  
Optionee has reviewed the Plan and this Option Agreement in their entirety, 
has had an opportunity to obtain the advice of counsel prior to executing 
this Option Agreement and fully understands all provisions of the Plan and 
Option Agreement. Optionee hereby agrees to accept as binding, conclusive and 
final all decisions or interpretations of the Administrator upon any 
questions relating to the Plan and Option Agreement.  Optionee further agrees 
to notify the Company upon any change in the residence address indicated

     This Security Agreement is made as of __________, 19___ between CATS 
Software Inc., a Delaware corporation ("Pledgee"), and _______________________
("Pledgor").

                                       RECITALS

     Pursuant to Pledgor's election to purchase Shares under the Option 
Agreement dated ________ (the "Option"), between Pledgor and Pledgee under 
Pledgee's Amended and Restated 1995 Stock Plan, and Pledgor's election under 
the terms of the Option to pay for such shares with his promissory note (the 
"Note"), Pledgor has purchased _________ shares of Pledgee's Common Stock 
(the "Shares") at a price of $________ per share, for a total purchase price 
of $__________.  The Note and the obligations thereunder are as set forth in 
Exhibit C to the Option.

     NOW, THEREFORE, it is agreed as follows:

     1.   CREATION AND DESCRIPTION OF SECURITY INTEREST.  In consideration of 
the transfer of the Shares to Pledgor under the Option Agreement, Pledgor, 
pursuant to the California Commercial Code, hereby pledges all of such Shares 
(herein sometimes referred to as the "Collateral") represented by certificate 
number ______, duly endorsed in blank or with executed stock powers, and 
herewith delivers said certificate to the Secretary of Pledgee 
("Pledgeholder"), who shall hold said certificate subject to the terms and 
conditions of this Security Agreement.

     The pledged stock (together with an executed blank stock assignment for 
use in transferring all or a portion of the Shares to Pledgee if, as and when 
required pursuant to this Security Agreement) shall be held by the 
Pledgeholder as security for the repayment of the Note, and any extensions or 
renewals thereof, to be executed by Pledgor pursuant to the terms of the 
Option, and the Pledgeholder shall not encumber or dispose of such Shares 
except in accordance with the provisions of this Security Agreement.

     2.   PLEDGOR'S REPRESENTATIONS AND COVENANTS.  To induce Pledgee to 
enter into this Security Agreement, Pledgor represents and covenants to 
Pledgee, its successors and assigns, as follows:

          a.   PAYMENT OF INDEBTEDNESS.  Pledgor will pay the principal sum 
of the Note secured hereby, together with interest thereon, at the time and 
in the manner provided in the Note.

          b.   ENCUMBRANCES.  The Shares are free of all other encumbrances, 
defenses and liens, and Pledgor will not further encumber the Shares without 
the prior written consent of Pledgee.

                                       

<PAGE>

          c.   MARGIN REGULATIONS.  In the event that Pledgee's Common Stock 
is now or later becomes margin-listed by the Federal Reserve Board and 
Pledgee is classified as a "lender" within the meaning of the regulations 
under Part 207 of Title 12 of the Code of Federal Regulations ("Regulation 
G"), Pledgor agrees to cooperate with Pledgee in making any amendments to the 
Note or providing any additional collateral as may be necessary to comply 
with such regulations.

     3.   VOTING RIGHTS.  During the term of this pledge and so long as all 
payments of principal and interest are made as they become due under the 
terms of the Note, Pledgor shall have the right to vote all of the Shares 
pledged hereunder.

     4.   STOCK ADJUSTMENTS.  In the event that during the term of the pledge 
any stock dividend, reclassification, readjustment or other changes are 
declared or made in the capital structure of Pledgee, all new, substituted 
and additional shares or other securities issued by reason of any such change 
shall be delivered to and held by the Pledgee under the terms of this 
Security Agreement in the same manner as the Shares originally pledged 
hereunder.  In the event of substitution of such securities, Pledgor, Pledgee 
and Pledgeholder shall cooperate and execute such documents as are reasonable 
so as to provide for the substitution of such Collateral and, upon such 
substitution, references to "Shares" in this Security Agreement shall include 
the substituted shares of capital stock of Pledgor as a result thereof.

     5.   OPTIONS AND RIGHTS.  In the event that, during the term of this 
pledge, subscription Options or other rights or options shall be issued in 
connection with the pledged Shares, such rights, Options and options shall be 
the property of Pledgor and, if exercised by Pledgor, all new stock or other 
securities so acquired by Pledgor as it relates to the pledged Shares then 
held by Pledgeholder shall be immediately delivered to Pledgeholder, to be 
held under the terms of this Security Agreement in the same manner as the 
Shares pledged.

     6.   DEFAULT.  Pledgor shall be deemed to be in default of the Note and 
of this Security Agreement in the event:

          a.   Payment of principal or interest on the Note shall be 
delinquent for a period of 10 days or more; or

          b.   Pledgor fails to perform any of the covenants set forth in the 
Option or contained in this Security Agreement for a period of 10 days after 
written notice thereof from Pledgee.

     In the case of an event of Default, as set forth above, Pledgee shall 
have the right to accelerate payment of the Note upon notice to Pledgor, and 
Pledgee shall thereafter be entitled to pursue its remedies under the 
California Commercial Code.

     7.   RELEASE OF COLLATERAL.  Subject to any applicable contrary rules under
Regulation G, there shall be released from this pledge a portion of the pledged
Shares held by Pledgeholder here-

                                       -2-

<PAGE>

under upon payments of the principal of the Note.  The number of the pledged 
Shares which shall be released shall be that number of full Shares which 
bears the same proportion to the initial number of Shares pledged hereunder 
as the payment of principal bears to the initial full principal amount of the 
Note.

     8.   WITHDRAWAL OR SUBSTITUTION OF COLLATERAL.  Pledgor shall not sell, 
withdraw, pledge, substitute or otherwise dispose of all or any part of the 
Collateral without the prior written consent of Pledgee.

     9.   TERM.  The within pledge of Shares shall continue until the payment 
of all indebtedness secured hereby, at which time the remaining pledged stock 
shall be promptly delivered to Pledgor, subject to the provisions for prior 
release of a portion of the Collateral as provided in paragraph 7 above.

     10.  INSOLVENCY.  Pledgor agrees that if a bankruptcy or insolvency 
proceeding is instituted by or against it, or if a receiver is appointed for 
the property of Pledgor, or if Pledgor makes an assignment for the benefit of 
creditors, the entire amount unpaid on the Note shall become immediately due 
and payable, and Pledgee may proceed as provided in the case of default.

     11.  PLEDGEHOLDER LIABILITY.  In the absence of willful or gross 
negligence, Pledgeholder shall not be liable to any party for any of his 
acts, or omissions to act, as Pledgeholder.

     12.  INVALIDITY OF PARTICULAR PROVISIONS.  Pledgor and Pledgee agree 
that the enforceability or invalidity of any provision or provisions of this 
Security Agreement shall not render any other provision or provisions herein 
contained unenforceable or invalid.

     13.  SUCCESSORS OR ASSIGNS.  Pledgor and Pledgee agree that all of the 
terms of this Security Agreement shall be binding on their respective 
successors and assigns, and that the term "Pledgor" and the term "Pledgee" as 
used herein shall be deemed to include, for all purposes, the respective 
designees, successors, assigns, heirs, executors and administrators.

     14.  GOVERNING LAW.  This Security Agreement shall be interpreted and 
governed under the internal substantive laws, but not the choice of law 
rules, of California.

                                  CATS SOFTWARE INC.
                                 AMENDED AND RESTATED
                                   1995 STOCK PLAN

                         RESTRICTED STOCK PURCHASE AGREEMENT

     Unless otherwise defined herein, the terms defined in the Plan shall 
have the same defined meanings in this Restricted Stock Purchase Agreement.

     WHEREAS the Purchaser named in the Notice of Grant, (the "Purchaser") is 
an Service Provider, and the Purchaser's continued participation is 
considered by the Company to be important for the Company's continued growth; 
and

     WHEREAS in order to give the Purchaser an opportunity to acquire an 
equity interest in the Company as an incentive for the Purchaser to 
participate in the affairs of the Company, the Administrator has granted to 
the Purchaser a Stock Purchase Right subject to the terms and conditions of 
the Plan and the Notice of Grant, which are incorporated herein by reference, 
and pursuant to this Restricted Stock Purchase Agreement (the "Agreement").

     NOW THEREFORE, the parties agree as follows:

     1.   SALE OF STOCK.  The Company hereby agrees to sell to the Purchaser 
and the Purchaser hereby agrees to purchase shares of the Company's Common 
Stock (the "Shares"), at the per Share purchase price and as otherwise 
described in the Notice of Grant.

     2.   PAYMENT OF PURCHASE PRICE.  The purchase price for the Shares may 
be paid by delivery to the Company at the time of execution of this Agreement 
of cash, a check, or some combination thereof.

     3.   REPURCHASE OPTION.

          (a)  In the event the Purchaser ceases to be a Service Provider for 
any or no reason (including death or disability) before all of the Shares are 
released from the Company's Repurchase Option (see Section 4), the Company 
shall, upon the date of such termination (as reasonably fixed and determined 
by the Company) have an irrevocable, exclusive option (the "Repurchase 
Option") for a period of sixty (60) days from such date to repurchase up to 
that number of shares which constitute the Unreleased Shares (as defined in 
Section 4) at the original purchase price per share (the "Repurchase Price"). 
The Repurchase Option shall be exercised by the Company by delivering 
written notice to the Purchaser or the Purchaser's executor (with a copy to 
the Escrow Holder) AND, at the Company's option, (i) by delivering to the 
Purchaser or the Purchaser's executor a check in the amount of the aggregate 
Repurchase Price, or (ii) by cancelling an amount of the Purchaser's 

<PAGE>

indebtedness to the Company equal to the aggregate Repurchase Price, or (iii) 
by a combination of (i) and (ii) so that the combined payment and 
cancellation of indebtedness equals the aggregate Repurchase Price.  Upon 
delivery of such notice and the payment of the aggregate Repurchase Price, 
the Company shall become the legal and beneficial owner of the Shares being 
repurchased and all rights and interests therein or relating thereto, and the 
Company shall have the right to retain and transfer to its own name the 
number of Shares being repurchased by the Company.

          (b)  Whenever the Company shall have the right to repurchase Shares 
hereunder, the Company may designate and assign one or more employees, 
officers, directors or shareholders of the Company or other persons or 
organizations to exercise all or a part of the Company's purchase rights 
under this Agreement and purchase all or a part of such Shares.  If the Fair 
Market Value of the Shares to be repurchased on the date of such designation 
or assignment (the "Repurchase FMV") exceeds the aggregate Repurchase Price 
of such Shares, then each such designee or assignee shall pay the Company 
cash equal to the difference between the Repurchase FMV and the aggregate 
Repurchase Price of such Shares.

     4.   RELEASE OF SHARES FROM REPURCHASE OPTION.

          (a)  _______________________  percent (______%) of the Shares shall 
be released from the Company's Repurchase Option _________ after the Date of 
Grant and __________________ percent (______%) of the Shares 
[_________________________], provided that the Purchaser does not cease to be 
a Service Provider prior to the date of any such release.

          (b)  Any of the Shares that have not yet been released from the 
Repurchase Option are referred to herein as "Unreleased Shares."

          (c)  The Shares that have been released from the Repurchase Option 
shall be delivered to the Purchaser at the Purchaser's request (see Section 
6).

     5.   RESTRICTION ON TRANSFER.  Except for the escrow described in 
Section 6 or the transfer of the Shares to the Company or its assignees 
contemplated by this Agreement, none of the Shares or any beneficial interest 
therein shall be transferred, encumbered or otherwise disposed of in any way 
until such Shares are released from the Company's Repurchase Option in 
accordance with the provisions of this Agreement, other than by will or the 
laws of descent and distribution.

     6.   ESCROW OF SHARES.

          (a)  To ensure the availability for delivery of the Purchaser's
Unreleased Shares upon repurchase by the Company pursuant to the Repurchase
Option, the Purchaser shall, upon execution of this Agreement, deliver and
deposit with an escrow holder designated by the Company (the "Escrow Holder")
the share certificates representing the Unreleased Shares, together with the
stock assignment duly endorsed in blank, attached hereto as Exhibit A-2.  The
Unreleased Shares and 

                                       -2-

<PAGE>

stock assignment shall be held by the Escrow Holder, pursuant to the Joint 
Escrow Instructions of the Company and Purchaser attached hereto as Exhibit 
A-3, until such time as the Company's Repurchase Option expires.  As a 
further condition to the Company's obligations under this Agreement, the 
Company may require the spouse of Purchaser, if any, to execute and deliver 
to the Company the Consent of Spouse attached hereto as Exhibit A-4.

          (b)  The Escrow Holder shall not be liable for any act it may do or 
omit to do with respect to holding the Unreleased Shares in escrow while 
acting in good faith and in the exercise of its judgment.

          (c)  If the Company or any assignee exercises the Repurchase Option 
hereunder, the Escrow Holder, upon receipt of written notice of such exercise 
from the proposed transferee, shall take all steps necessary to accomplish 
such transfer.

          (d)  When the Repurchase Option has been exercised or expires 
unexercised or a portion of the Shares has been released from the Repurchase 
Option, upon request the Escrow Holder shall promptly cause a new certificate 
to be issued for the released Shares and shall deliver the certificate to the 
Company or the Purchaser, as the case may be.

          (e)  Subject to the terms hereof, the Purchaser shall have all the 
rights of a shareholder with respect to the Shares while they are held in 
escrow, including without limitation, the right to vote the Shares and to 
receive any cash dividends declared thereon.  If, from time to time during 
the term of the Repurchase Option, there is (i) any stock dividend, stock 
split or other change in the Shares, or (ii) any merger or sale of all or 
substantially all of the assets or other acquisition of the Company, any and 
all new, substituted or additional securities to which the Purchaser is 
entitled by reason of the Purchaser's ownership of the Shares shall be 
immediately subject to this escrow, deposited with the Escrow Holder and 
included thereafter as "Shares" for purposes of this Agreement and the 
Repurchase Option.

     7.   LEGENDS.  The share certificate evidencing the Shares, if any,  
issued hereunder shall be endorsed with the following legend (in addition to 
any legend required under applicable state securities laws):

     THE SHARES REPRESENTED BY THIS CERTIFICATE ARE SUBJECT TO CERTAIN 
RESTRICTIONS UPON TRANSFER AND RIGHTS OF REPURCHASE AS SET FORTH IN AN 
AGREEMENT BETWEEN THE COMPANY AND THE SHAREHOLDER, A COPY OF WHICH IS ON FILE 
WITH THE SECRETARY OF THE COMPANY.

     8.   ADJUSTMENT FOR STOCK SPLIT.  All references to the number of Shares 
and the purchase price of the Shares in this Agreement shall be appropriately 
adjusted to reflect any stock split, stock dividend or other change in the 
Shares which may be made by the Company after the date of this Agreement.

                                       -3-

     9.   TAX CONSEQUENCES.  The Purchaser has reviewed with the Purchaser's 
own tax advisors the federal, state, local and foreign tax consequences of 
this investment and the transactions contemplated by this Agreement.  The 
Purchaser is relying solely on such advisors and not on any statements or 
representations of the Company or any of its agents.  The Purchaser 
understands that the Purchaser (and not the Company) shall be responsible for 
the Purchaser's own tax liability that may arise as a result of the 
transactions contemplated by this Agreement.  The Purchaser understands that 
Section 83 of the Internal Revenue Code of 1986, as amended (the "Code"), 
taxes as ordinary income the difference between the purchase price for the 
Shares and the Fair Market Value of the Shares as of the date any 
restrictions on the Shares lapse.  In this context, "restriction" includes 
the right of the Company to buy back the Shares pursuant to the Repurchase 
Option.  The Purchaser understands that the Purchaser may elect to be taxed 
at the time the Shares are purchased rather than when and as the Repurchase 
Option expires by filing an election under Section 83(b) of the Code with the 
IRS within 30 days from the date of purchase.  The form for making this 
election is attached as Exhibit A-5 hereto.

          THE PURCHASER ACKNOWLEDGES THAT IT IS THE PURCHASER'S SOLE 
RESPONSIBILITY AND NOT THE COMPANY'S TO FILE TIMELY THE ELECTION UNDER 
SECTION 83(b), EVEN IF THE PURCHASER REQUESTS THE COMPANY OR ITS 
REPRESENTATIVES TO MAKE THIS FILING ON THE PURCHASER'S BEHALF.

     10.  GENERAL PROVISIONS.

          (a)  This Agreement shall be governed by the internal substantive 
laws, but not the choice of law rules of California.  This Agreement, subject 
to the terms and conditions of the Plan and the Notice of Grant, represents 
the entire agreement between the parties with respect to the purchase of the 
Shares by the Purchaser.  Subject to Section 15(c) of the Plan, in the event 
of a conflict between the terms and conditions of the Plan and the terms and 
conditions of this Agreement, the terms and conditions of the Plan shall 
prevail.  Unless otherwise defined herein, the terms defined in the Plan 
shall have the same defined meanings in this Agreement.

          (b)  Any notice, demand or request required or permitted to be

Dear _____________:

     As Escrow Agent for both CATS Software Inc., a Delaware corporation (the 
"Company"), and the undersigned purchaser of stock of the Company (the 
"Purchaser"), you are hereby authorized and directed to hold the documents 
delivered to you pursuant to the terms of that certain Restricted Stock 
Purchase Agreement ("Agreement") between the Company and the undersigned, in 
accordance with the following instructions:

     1.   In the event the Company and/or any assignee of the Company 
(referred to collectively as the "Company") exercises the Company's 
Repurchase Option set forth in the Agreement, the Company shall give to 
Purchaser and you a written notice specifying the number of shares of stock 
to be purchased, the purchase price, and the time for a closing hereunder at 
the principal office of the Company.  Purchaser and the Company hereby 
irrevocably authorize and direct you to close the transaction contemplated by 
such notice in accordance with the terms of said notice.

     2.   At the closing, you are directed (a) to date the stock assignments 
necessary for the transfer in question, (b) to fill in the number of shares 
being transferred, and (c) to deliver same, together with the certificate 
evidencing the shares of stock to be transferred, to the Company or its 
assignee, against the simultaneous delivery to you of the purchase price (by 
cash, a check, or some combination thereof) for the number of shares of stock 
being purchased pursuant to the exercise of the Company's Repurchase Option.

     3.   Purchaser irrevocably authorizes the Company to deposit with you 
any certificates evidencing shares of stock to be held by you hereunder and 
any additions and substitutions to said shares as defined in the Agreement. 
Purchaser does hereby irrevocably constitute and appoint you as Purchaser's 
attorney-in-fact and agent for the term of this escrow to execute with 
respect to such securities all documents necessary or appropriate to make 
such securities negotiable and to complete any transaction herein 
contemplated, including but not limited to the filing with any applicable 
state blue sky authority of any required applications for consent to, or 
notice of transfer of, the securities.  Subject to the provisions of this 
paragraph 3, Purchaser shall exercise all rights and privileges of a 
shareholder of the Company while the stock is held by you.

<PAGE>

     4.   Upon written request of the Purchaser, but no more than once per 
calendar year, unless the Company's Repurchase Option has been exercised, you 
shall deliver to Purchaser a certificate or certificates representing so many 
shares of stock as are not then subject to the Company's Repurchase Option. 
Within 90 days after Purchaser ceases to be a Service Provider, you shall 
deliver to Purchaser a certificate or certificates representing the aggregate 
number of shares held or issued pursuant to the Agreement and not purchased 
by the Company or its assignees pursuant to exercise of the Company's 
Repurchase Option.

     5.   If at the time of termination of this escrow you should have in 
your possession any documents, securities, or other property belonging to 
Purchaser, you shall deliver all of the same to Purchaser and shall be 
discharged of all further obligations hereunder.

     6.   Your duties hereunder may be altered, amended, modified or revoked 
only by a writing signed by all of the parties hereto.

     7.   You shall be obligated only for the performance of such duties as 
are specifically set forth herein and may rely and shall be protected in 
relying or refraining from acting on any instrument reasonably believed by

parties. You shall not be personally liable for any act you may do or omit to 
do hereunder as Escrow Agent or as attorney-in-fact for Purchaser while 
acting in good faith, and any act done or omitted by you pursuant to the 
advice of your own attorneys shall be conclusive evidence of such good faith.

     8.   You are hereby expressly authorized to disregard any and all 
warnings given by any of the parties hereto or by any other person or 
corporation, excepting only orders or process of courts of law, and are 
hereby expressly authorized to comply with and obey orders, judgments or 
decrees of any court. In case you obey or comply with any such order, 
judgment or decree, you shall not be liable to any of the parties hereto or 
to any other person, firm or corporation by reason of such compliance, 
notwithstanding any such order, judgment or decree being subsequently 
reversed, modified, annulled, set aside, vacated or found to have been 
entered without jurisdiction.

     9.   You shall not be liable in any respect on account of the identity, 
authorities or rights of the parties executing or delivering or purporting to 
execute or deliver the Agreement or any documents or papers deposited or 
called for hereunder.

     10.  You shall not be liable for the outlawing of any rights under the 
statute of limitations with respect to these Joint Escrow Instructions or any 
documents deposited with you.

     11.  You shall be entitled to employ such legal counsel and other 
experts as you may deem necessary properly to advise you in connection with 
your obligations hereunder, may rely upon the advice of such counsel, and may 
pay such counsel reasonable compensation therefor.

<PAGE>

     12.  Your responsibilities as Escrow Agent hereunder shall terminate if 
you shall cease to be an officer or agent of the Company or if you shall 
resign by written notice to each party.  In the event of any such 
termination, the Company shall appoint a successor Escrow Agent.

     13.  If you reasonably require other or further instruments in 
connection with these Joint Escrow Instructions or obligations in respect 
hereto, the necessary parties hereto shall join in furnishing such 
instruments.

     14.  It is understood and agreed that should any dispute arise with 
respect to the delivery and/or ownership or right of possession of the 
securities held by you hereunder, you are authorized and directed to retain 
in your possession without liability to anyone all or any part of said 
securities until such disputes shall have been settled either by mutual 
written agreement of the parties concerned or by a final order, decree or 
judgment of a court of competent jurisdiction after the time for appeal has 
expired and no appeal has been perfected, but you shall be under no duty 
whatsoever to institute or defend any such proceedings.

     15.  Any notice required or permitted hereunder shall be given in 
writing and shall be deemed effectively given upon personal delivery or upon

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

THIS REPORT CONTAINS CERTAIN FORWARD-LOOKING STATEMENTS WITHIN THE MEANING OF 
SECTION 27A OF THE SECURITIES ACT OF 1933 AND SECTION 21E OF THE SECURITIES 
EXCHANGE ACT OF 1934.  THE COMPANY'S ACTUAL RESULTS COULD DIFFER MATERIALLY 
FROM THE RESULTS ANTICIPATED IN THESE FORWARD-LOOKING STATEMENTS AS A RESULT 
OF CERTAIN FACTORS SET FORTH IN "MANAGEMENT'S DISCUSSION AND ANALYSIS OF 
FINANCIAL CONDITION AND RESULTS OF OPERATIONS" AND ELSEWHERE IN THIS REPORT.

OVERVIEW

     C-ATS Software Inc. (the "Company" or "C-ATS") was organized in 1988 as a 
successor to a partnership formed in 1986. The Company's first product, 
SWAPWARE-Registered Trademark-, was released in 1986. The Company has since 
introduced additional products such as OPTIONS, FUTURES AND BONDS, MARKET 
DATA, RISK MANAGER and OPERATIONS MANAGER. In late 1994, the Company 
introduced C-ATALYST, an enhanced version of its product family which 
includes multiple front, middle, and back office modules for capital markets, 
derivatives trading, and risk management. These products serve the 
established market for derivatives risk management and the emerging market 
for enterprise-wide risk management.  During February 1996, the Company 
acquired the assets of LOR/Geske Bock Associates, Inc. ("LOR/Geske Bock" or 
"LORGB") and developed and released an enhanced version of CARMA-Registered 
Trademark-, which extends the Company's offerings for Enterprise-wide risk 
management solutions. While the Company was profitable on an annual basis 
from 1992 through 1995, R&D expenses associated with the acquisition of 
LOR/Geske Bock resulted in a net loss for 1996.  In 1997, the Company 
acquired the rights to the software technology of International Risk Control, 
Inc. ("International Risk Control") providing the Company with technology for 
trading and risk management of foreign currency derivatives.  This 
acquisition and continued investment in R&D, Sales, Marketing, and 
Administration resulted in a net loss in 1997.  The Company's revenues are 
derived primarily from annual renewable license fees.  International revenues 
accounted for 83%, 80% and 80% of total revenues in 1997, 1996 and 1995, 
respectively.

LICENSE AND SERVICE REVENUE

     Total revenues were $18.5 million in 1997, down 8% from $20.1 million  
in revenues in 1996 and 17% from the $22.3 million in 1995. The Company's 
revenues are derived primarily from annual renewable license fees. These fees 
are non-refundable, are typically payable in full at the beginning of the 
annual term and are recognized pro-rata over the term of the license.  The 
annual renewable license fee includes rights to use the Company's software 
products, updates to the products, if any, product installation, initial 
client training, documentation and software support services for one year. In 
addition to its annual licenses, the Company makes available its services on 
a contract basis to assist clients with services beyond those included in its 
licenses. These services typically include additional client training and 
assisting clients in their generation of client-specific reports, data base 
integration and system optimization. In the fall of 1997, the Company formed 
a new division, the C-ATS Consulting Group, to provide consulting services 
and assist clients in implementing risk management solutions. These services 
include implementation planning, integration assistance (including 
implementation tools) and project management expertise. Revenues from such 
projects are included in service and other revenues.  They are recognized 
when delivered or based upon the percentage-of-completion method and are 
typically affected by the commencement or completion of significant services 
projects. 

     License revenue decreased to $17.3 million in 1997 from $19.3 million in 
1996 and $20.4 million in 1995.  License revenue decreased in both 1997 and 
1996 as a result of the decisions of some clients to not renew annual 
licenses.  Such decisions are attributable to numerous factors, but 
principally are the result of consolidations within the banking industry and 
the election of several customers to utilize in-house developed programs.

     The Company licenses its products on a per site basis with the price per 
site varying based upon the selection of products licensed, the number of 
authorized users for each product at each site and the number of licensed 
sites.  As a result, total revenues in any year depend upon the number of new 
and renewed annual licenses, the number of sites which use the Company's 
products, product prices, and the number of users per site.  Average revenue 
per site increased by 6% in 1997, 6% in 1996 and 8% in 1995. The Company 
believes the average revenue per site has increased because the Company 
continues to offer new products and enhancements to existing products, and 
because clients have increased the number of users licensed per site, factors 
which have been partially offset by declines in unit pricing per product.  
Although the Company has historically been able to offset declines in unit 
pricing with increases in functionality and new product introductions, there 
can be no assurance that the Company will continue to introduce new products 
or enhancements to existing products or that such products when introduced 
will result in increased revenue per client site. 

     Service and other revenue increased to $1.2 million in 1997 from $0.8 
million in 1996 but decreased from $1.9 million in 1995. Service and other 
revenue increased in 1997 from 1996 primarily due to the initiation of trial 
projects related to the Company's release of its CARMA products and to the 
formation of the C-ATS Consulting Group.  Service and other revenue decreased 
in 1996 primarily due to completion in late 1995 of a $1.5 million  systems 
integration project that was undertaken and subcontracted by the Company in 
the middle of 1994.  Assuming customer acceptance of the CARMA products, the 
Company anticipates that service  revenue will continue  to grow in 
proportion to licensing opportunities of the CARMA products.

COST OF REVENUES

     Cost of revenues includes the cost of documentation materials, royalties 
and the cost of subcontracted services. Costs of revenues were $0.3 million, 
$0.3 million and $1.2 million in 1997, 1996 and 1995, respectively.  The 
reduction in 1996 cost of revenues to $0.3 million from $1.2 million in 1995, 
is attributable to reductions in the cost of subcontracted services for a 
systems integration project that was completed in the fourth quarter of 1995.

RESEARCH AND DEVELOPMENT

     Most of the Company's research and development expenditures are 
personnel related. Total expenditures for research and development increased 
to $6.7 million in 1997 from $6.2 million in 1996 and $3.6 million in 1995.  
The increase in research and development expenditures was due primarily to 
increases in expenditures for continuation and completion of purchased 
in-process research ($3.4 million in 1997 and $2.8 million in 1996), a one 
time charge of $0.6 million in connection with the third quarter of 1997 
acquisition of rights to the software of International Risk Control and new 
product development. The increase in 1996 includes the addition of 
research staff from the acquired firm of LOR/Geske Bock during the first 
quarter of 1996.  In connection with the LOR/Geske Bock acquisition, the 
Company recognized a one-time expense amounting to $7.1 million of in process 
research and development as the technology had not yet reached technological 
feasibility and does not have alternative future uses (See Note 3 of the 
Notes to the Consolidated Financial Statements). The amounts of ongoing 
software development costs which could have been capitalized in accordance 
with Statement of Financial Accounting Standards No. 86," were immaterial 
and, therefore, no software development costs have been capitalized by the 
Company to date. The Company believes that significant investment for product 
research and development is essential to product and technical leadership, 
and the Company anticipates that it will continue to commit substantial 
resources to research and development in the future. The focus of this 
increased research and development spending will be to expand the platforms 
upon which the Company's products operate; to integrate the acquired products 
from LORGB; and to continue to enhance the features and functionality of the 
company's products.  The Company anticipates that research and development 
expenditures will increase in dollar amount in 1998.

SALES AND MARKETING

     Sales and marketing expenses consist principally of salary, commissions 
and facilities related costs. Sales and marketing expenditures increased to 
$11.4 million in 1997 from $11.1 million in 1996 and $10.3 million in 1995.  
The increase in sales and marketing in 1997 was primarily due to increases 
associated with the sales and marketing of the Company's expanded product 
line in the North American market. The increase in sales and marketing 
expenditures in 1996 was due to increases in personnel, commissions, 
marketing communication programs and the expansion of the Company's Hong Kong 
office. The Company anticipates that sales and marketing expenses will 
continue to increase in dollar amount in 1998 as it expands its sales and 
consulting service organization and promotes its CARMA products. 

GENERAL AND ADMINISTRATIVE

     General and administrative expenses consist primarily of personnel costs 
for finance, contract administration, human resources and general management, 
as well as legal, accounting and auditing expenses. General and 
administrative expenses increased to $3.0 million in 1997 from $2.6 million 
in 1996 and $2.8 million in 1995. The increase in general and administrative 
expenses in 1997 was due to additional executive staff to support the 
expanding international sales and employee recruiting. The decrease in 
general and administrative expenses in 1996 from 1995 was due to reduced 
costs of professional services subsequent to becoming a publicly held 
company. The Company anticipates that general and administrative expenses 
will increase in dollar amount in 1998.

INTEREST INCOME

     Interest income is comprised primarily of interest earned on the 
Company's surplus cash and short-term investment balances, net of interest 
expense. Interest income increased to $1.0 million in 1997 from $0.9 million 
in 1996 and 1995.  Interest income increased in 1997 due to higher investment 
yields on lower average cash and short-term investment balances. 

PROVISION FOR INCOME TAXES

     The Company accounts for income taxes in accordance with Statement of 
Financial Accounting Standards No. 109, "Accounting for Income Taxes," which 
provides for a liability approach under which deferred income taxes are 
provided based upon enacted laws and rates applicable to the periods in which 
the taxes become payable.  There was no provision for income taxes in 1997 
and 1996 due to the Company's net operating loss position.  The provision for 
income taxes was 35% of income (loss) before the provision for income taxes 
in 1995.  The provision for income taxes takes into account the effects of 
foreign income taxes and state income taxes, offset by utilization of 
research and development and foreign tax credits. 

     As of December 31, 1997, the Company had $6.2 million of deferred tax 
assets. Due to certain limitations of benefits related to tax carrybacks and 
the current year net operating loss position, and the uncertainty of future 
results, the Company has provided a valuation allowance of $3.6 million 
related to the deferred tax asset. The Company's tax returns for 1990 through 
1993 are currently being examined by the Internal Revenue Service relating to 
the treatment of foreign withholding taxes on the Company's software license 
revenue under tax treaties in effect during those years. Such examination may 
result in adjustments to previously filed tax returns.  The Company is 
currently seeking competent authority relief, which, if successful, will 
eliminate any potential double taxation. While the Company believes that it 
has reserves sufficient to cover any actual tax liabilities as a result of 
this examination, no assurance can be given that the reserves will be 
adequate.  See Note 6 of the Notes to Consolidated Financial Statements. 

QUARTERLY INFORMATION

     The following table presents unaudited quarterly financial information 
for the eight quarters ended December 31, 1997.  Management believes this 
information has been prepared on the same basis as the audited Consolidated 
Financial Statements and that all necessary adjustments (consisting only of 
normal recurring adjustments) have been included to present fairly the 
unaudited quarterly results. The following should be read in conjunction with 
the audited Consolidated Financial Statements of the Company and the Notes 
appearing elsewhere in these Consolidated Financial Statements. These 
operating results are not necessarily indicative of results for any future 
period.

     The Company's license revenue increased in each quarter of 1997.  
Incremental sales to existing clients and new license agreements offset 
non-renewing licenses during the year. The Company's historical practice has 
been to recognize revenue from its annually renewable license fees pro-rata 
over the license term. Therefore the revenue impact from adding new customers 
has been reflected over several quarters following sales consummation. The 
Company began offering multi-year (typically five year) term licenses in the 
fourth quarter of 1997 with optional annual maintenance.  With this new 
licensing model, the Company will recognize substantial revenues upon 
delivery of the product.  In addition, there may be additional maintenance 
revenues, recognized ratably as such services are provided.  The Company has 
not yet entered into any such multi-year term licenses.  Service and other 
revenue is recognized when delivered or using the 

                                       8

percentage-of-completion method and is typically affected by the commencement 
or completion of significant services projects.

     Cost of revenues has been relatively minor. The Company has generally 
increased operating expenses to support higher revenue levels and product 
development efforts.  Research and development costs were higher in 1997 as 
compared to 1996 due to increases in staffing to support final development 
and testing of the newest CARMA product line release. Sales and marketing 
costs were higher in 1997 as compared to 1996 due to increases in staffing of 
the North American office and the development of the Company's consulting 
service.  General and administrative costs were higher on a dollar basis in 
1997 as compared to 1996 due to hiring of executive and human resource 
personnel to support the staffing needs of the  expanding international sales 
and marketing and customer service offices.

     Although the Company's installed base of C-ATALYST customers has 
stabilized in terms of number of clients and number of client sites, there 
can be no assurance that the Company will continue to be able to renew its 
existing client base or expand the number of clients or client sites where 
the Company's products are licensed.  A number of factors affect a client's 
decision to license or continue to license the Company's products. These 
factors include the status of a client's internal systems development 
programs, competitiveness of the Company's current product offerings, 
pricing, and level of satisfaction with the Company's sales, service and 
support staff.  From time to time in the past, the Company has experienced 
delays in developing and introducing new products, which has slowed the rate 
of growth. There can be no assurance that similar delays may not occur in the 
future. The Company's expense levels are based, in part, on expectations of 
future revenues. If revenues do not meet expectations, operating results 
could be adversely affected.  Net income may be disproportionately affected 
by a change in revenues because only a small portion of the Company's 
expenses varies with revenues.

LIQUIDITY AND CAPITAL RESOURCES

     The Company has funded its operations to date through cash flow from 
operations and its initial public offering of stock effective March 20, 1995. 
 As of December  31, 1997, the Company had $20.2 million in cash, cash 
equivalents and short-term investments, and no long-term debt.  Short-term 
investments consist principally of auction market preferred stock and 
tax-preferred securities.

     Net cash utilized by operating activities totaled $1.8 million in 1997, 
while $1.0 million in 1996 and approximately $3.1 million was provided by 
operating activities in 1995. Investing activities used net cash of 
approximately $1.9 million, $3.4 million and $21.0 million in 1997, 1996 and 
1995, respectively. Inclusive within these uses were the purchase of 
short-term investments of approximately $20.2 million in 1995, and the 
subsequent sale in 1996 of $7.4 million of these short-term investments which 
were used to help fund the approximately $3.3 million cash portion of the 
investment in LORGB the same year.  Net cash flows provided by financing 
activities were approximately $0.5 million, $0.3 million and $14.3 million in 
1997, 1996 and 1995, respectively with $13.8 million of the net cash in 1995 
provided by the Company's initial public offering that year.  The Company 
purchased approximately $0.5 million of property and equipment in 1997, and 
$0.7 million in both 1996 and 1995.  The Company has no other significant 
capital commitments.

     On February 13, 1996, C-ATS Sub, Inc. (a wholly owned subsidiary of  the 
Company), merged with LOR/Geske Bock Associates, Inc. ("LORGB"), a California 
Corporation, pursuant to an "Agreement and Plan of Reorganization" dated 
January 30, 1996.  LORGB designs, develops, and markets integrated, 
organization-wide market and credit risk management software systems. As a 
result of the merger, LORGB ceased to exist  while C-ATS Sub, Inc. continued 
as the surviving corporation.  The transaction was accounted for as a 
"purchase" and accordingly, the operating results of the acquired business 
have been included in the consolidated statement of operations from the date 
of the acquisition.

                                       9

<PAGE>

     At the consummation of the merger, the outstanding LORGB common stock 
was exchanged for an aggregate of approximately 578,651 shares of the 
Company's common stock (the stock price was valued at $7.00 as of the merger 
date) and approximately $3,294,000 in cash.  In addition, the Company assumed 
all options, representing the right to purchase approximately 167,000 shares 
of the Company's common stock.

     Historically, more client licenses are due for renewal in the second and 
fourth quarters of each year than in the first and third quarters. Because of 
the Company's pro-rata revenue recognition policy, this pattern has not had a 
significant impact on quarterly revenues. However, this pattern has and will 
likely continue to impact the timing of cash flows and the Company's cash and 
accounts receivable balances. Any decline or delay in contract renewals could 
have a material adverse effect on the Company's cash balances. 

     The Company believes that available funds, and the cash flow expected to 
be generated from operations will be adequate to meet the Company's 
anticipated working capital and capital expenditure requirements for at least 
the next twelve months.      

FACTORS THAT MAY AFFECT FUTURE RESULTS

     The Company's business, financial condition and results of operations 
can be impacted by a number of factors including without limitation the 
following factors.

CONTINUED DEPENDENCE ON DERIVATIVES RISK MANAGEMENT PRODUCT 

     C-ATS has derived substantially all of its revenues from the sale of 
software products and services for derivatives risk management, and its 
future growth is critically dependent on increased revenues from products for 
this use. The target clients for the Company's products include large banks 
and financial institutions, many of whom rely on internally developed 
derivative risk management systems. Their acceptance of the Company's 
products depends, among other things, on the products' functionality and 
performance characteristics, the ability of these clients to achieve cost 
savings by using third party software, the development time and cost of 
internally developed software, the willingness of these institutions to rely 
on third party software for mission critical financial applications, and 
their assessment of C-ATS' financial resources as well as its technical, 
managerial, service and support capabilities. The Company has generally found 
that the costs of switching to a new derivatives risk management system are 
so substantial that clients will generally not change systems unless they 
perceive a significant deficiency with their existing system. 

     A number of factors could adversely affect market acceptance of the 
Company's products for derivatives risk management applications. First, 
although the Company's products include software applications for a number of 
widely traded derivatives, such as swaps, options, swaptions and futures, 
they do not include software applications for many other derivative 
instruments. Although applications for these derivatives can be developed 
using FiCAD or may be included in the Company's future products,  the absence 
of applications for specific derivatives may reduce market acceptance of the 
Company's products. Second, some financial institutions may require a higher 
level of product customization and technical support than is customarily 
provided by C-ATS.   To the extent these clients cannot obtain this support 
from C-ATS  or third party service organizations, they may be reluctant to 
use the Company's products. Finally, C-ATALYST and CARMA have a long sales 
cycle that can adversely affect sales and increase marketing costs. As a 
result of these and other factors, there can be no assurance that C-ATALYST 
and CARMA will achieve significant market acceptance. 

EARLY STAGE OF DEVELOPMENT OF MARKET FOR ENTERPRISE-WIDE RISK MANAGEMENT; NO
ASSURANCE OF MARKET ACCEPTANCE OF ENTERPRISE-WIDE RISK MANAGEMENT PRODUCTS

     The market for enterprise-wide risk management software products is in 
an early stage of development. Although many financial institutions and 
organizations are exploring enterprise-wide risk 

                                       10

management, C-ATS believes that only a small number of enterprises have 
actually implemented enterprise-wide risk management systems. A number of 
factors will determine when and if a significant market for enterprise-wide 
risk management software products develops, including regulatory actions, 
client education and awareness of the need for enterprise-wide risk 
management and the availability of commercially accepted enterprise-wide risk 
management systems. Even if a significant market develops, there can be no 
assurance that the Company's products will achieve commercial acceptance. 

     First, there can be no assurance that the Company's approach to 
enterprise-wide risk management will be accepted in the marketplace. Although 
several companies are using prior versions of the Company's products for 
site-wide or enterprise-wide risk  management, the newest version of CARMA 
was released for commercial sales in December 1996.  This product is a 
substantial enhancement of the product obtained in the acquisition of 
LOR/Geske Bock, designed for enterprise-wide market and credit risk 
management.  While financial institutions are potentially subject to 
regulatory guidelines to implement a enterprise-wide market risk management 
system, there can be no assurance that the Company's products will achieve 
substantial acceptance in the marketplace.

     Second, although the Company's products facilitates enterprise-wide risk 
management, the process of creating a enterprise-wide risk management system 
can be extremely complex and in most cases requires substantial additional 
software engineering and integration in order to connect the many independent 
systems in place at most institutions and to link these systems to the 
Company's products. The cost of such a process is likely to far exceed the 
cost of licensing the Company's products. There is no assurance that a 
significant number of institutions will be willing to undertake such a large 
project or to incur such costs. Third, many institutions implementing 
enterprise-wide risk management will require substantial outside assistance 
in software engineering. The Company intends primarily to provide standard 
products and to rely on third parties to provide such assistance. Revenues 
from enterprise-wide risk management products will be limited if such 
third-party support is not readily available. Fourth, the development of 
sophisticated enterprise-wide risk management systems will depend on the 
availability of extensive transaction and counterparty data which the client 
must provide for portfolios not managed with the Company's products. Lack of 
access to such data may restrict an institution's ability to perform 
enterprise-wide risk management.

     Finally, many of the factors that affect market acceptance of the 
Company's products for derivatives risk management, such as the decision to 
develop software internally or rely on third-party software, also will affect 
market acceptance of the Company's products for enterprise-wide risk 
management. See "Factors That May Affect Future Results -- Continued 
Dependence on Derivatives Risk Management Products." Failure of a significant 
market for enterprise-wide risk management products to develop or, if it 
does, failure of the Company's products to achieve broad market acceptance 
could have a material adverse affect on the Company's business, operating 
results and financial condition. 

LIMITED SUPPORT, TRAINING AND CUSTOMIZATION

     Some financial institutions may require a higher level of product 
customization and technical support and training than the Company customarily 
provides or can provide. The Company intends primarily to rely on third 
parties to provide such customization and support. Additionally, the Company 
has limited resources to devote to training. To the extent financial 
institutions cannot obtain desired levels of customization, support and 
training, they may be reluctant to use the Company's products, which could 
slow market acceptance of the Company's products. This could impede the 
Company's growth and could have a material adverse effect on the Company's 
business, operating results and financial condition. 

                                       11

POTENTIAL FLUCTUATIONS IN QUARTERLY RESULTS

     The Company's quarterly operating results may fluctuate substantially as 
a result of a variety of factors including the volume and timing of license 
renewals by existing clients, license agreements with new clients, the timing 
and market acceptance of new products or technological advances by the 
Company or its competitors, price levels, and unexpected expenses. The 
Company's expense levels are based, in part, on expectations of future 
revenues. If revenues in a particular quarter do not meet expectations, 
operating results could be adversely affected. The Company expects that its 
operating results will fluctuate in the future as a result of these and other 
factors. Additionally, the Company has accrued a reserve for tax liabilities 
in connection with an Internal Revenue Service examination. There can be no 
assurance that such reserve will be adequate to cover all potential 
liabilities.  Results of past quarters should not be relied on as an 
indication of future results.  See Note 6 of the Notes to Consolidated 
Financial Statements.

DEPENDENCE ON RENEWABLE LICENSES; SIGNIFICANT POTENTIAL PRICE COMPETITION

     The Company's revenues are derived primarily from annual renewable 
license fees. These fees are non-refundable, typically paid in full at the 
beginning of the annual term and recognized as revenue pro-rata over the term 
of license. The Company has been successful to date in negotiating renewable 
licenses. Beginning in the fourth quarter of 1997, the Company began offering 
multi-year term licenses.  The Company believes this choice will be favorably 
received by its clients.  Many of the Company's competitors offer multi-year 
licenses. Although no clients have as yet selected the multi-year term 
license in 1997, the Company expects some clients will do so in 1998. A 
multi-year term license may result in larger fluctuations in revenues than 
the Company has historically experienced as multi-year term license revenue 
will be recognized at the time of delivery and completion of customer 
commitment and there will be no future license revenue amortization.  A 
significant decline in the percentage of clients who renew their license or 
the failure of the Company to continue to enter into renewable or limited 
term licenses would have a material adverse effect on the business, operating 
results and financial condition of the Company. 

     Because the software industry is intensely competitive, software 
products have often experienced price erosion. As is typical in the industry, 
the Company's fixed costs as a percentage of revenues are high, and 
significant price erosion could have a material adverse effect on the 
Company's business, operating results and financial condition.  Although to 
date any price decline in unit prices of the Company's products has been 
offset by the introduction of new or enhanced products, there can be no 
assurance that significant price erosion will not occur in the future.

DEPENDENCE ON INTERNATIONAL OPERATIONS AND SALES 

     Clients outside the United States accounted for approximately 83%, 80% 
and 80% of the Company's revenues in 1997, 1996 and 1995, respectively. The 
Company anticipates that its revenues for the next several years will also 
substantially derive from international sales. The Company markets and 
licenses its products outside the United States through its international 
branch offices and subsidiaries. The Company has offices in Tokyo, London, 
and Hong Kong as well as the United States, and the Company has licensed 
clients in 19 countries. International sales and operations may be limited or 
disrupted by the imposition of government controls, export license 
requirements, political instability, trade restrictions, changes in tariffs 
and exchange rates, difficulties in staffing, coordinating communications, 
managing international operations and other factors. The Company normally 
prices its products in U.S. dollars, but it incurs expenses in local 
currencies for its overseas operations. 

     The Company attempts to reduce its exposure to exchange rate 
fluctuations by purchasing foreign currencies every several months in amounts 
equal to the operating expenses estimated to be payable in such currencies 
during the next one to three months.  As of December 31, 1997, the Company 
held cumulative

                                       12

<PAGE>

foreign currencies available in the amount of approximately $280,000 to fund 
future expected operating expenses. However, no assurance can be given that 
this strategy will be sufficient to offset any dramatic declines in the value 
of the U.S. dollar. Regulatory compliance requirements differ among foreign 
countries and are also different from those established in the United States, 
and any inability to obtain necessary foreign regulatory approvals on a 
timely basis could have an adverse effect on the Company's international 
sales, and thereby on its business, financial condition and results of 
operations. Additionally, the Company's business, financial condition and 
international operating results may be adversely affected by fluctuations in 
currency exchange rates as well as increases in duty rates, difficulties in 
obtaining export licenses, ability to maintain or increase prices and 
competition.

DEPENDENCE ON KEY PERSONNEL; SUBSTANTIAL EXECUTIVE COMPENSATION

     The Company's success depends to a significant extent upon the 
contributions of its executive officers, and key sales, marketing, technical 
service and engineering personnel.  None of the Company's personnel are 
subject to a noncompetition agreement or other long-term employment contract 
with the Company. Further, in order to attract and retain its executive 
officers, the Company has in the past paid to its executive officers 
substantial compensation and bonuses. In addition, the Company's future 
success will depend significantly on its continuing ability to attract and 
retain highly qualified technical, sales and marketing personnel. Because the 
Company's business requires that many of these personnel have specialized 
knowledge of advanced computer programming and financial theory, and because 
the pool of such qualified personnel is extremely limited, competition for 
such personnel is intense, particularly among the Company's clients who have 
substantially greater financial resources than the Company.  Failure to 
attract and retain such personnel could have a material adverse affect on the 
Company's business, operating results and financial condition. 

NEW MANAGEMENT RESPONSIBILITIES; GROWTH

     Many of the Company's executive officers have joined the Company in the 
last twenty- four months.  Although each of the new executives brings 
significant prior experience to the Company, some are new to the Company's 
specific business segment.  In addition, future growth will require increased 
personnel, expanded information systems and additional financial and 
administrative control procedures, particularly because the Company has 
significant international operations. There can be no assurance that the 
Company would be able to attract and retain additional qualified personnel or 
successfully manage expanding operations, including an increasing number of 
client relationships and geographically dispersed locations or maintain 
adequate managerial, financial and operating systems and controls

DEPENDENCE ON DIRECT SALES FORCE; ABSENCE OF INDIRECT SALES CHANNELS.

     C-ATS currently distributes its products exclusively through its direct 
sales force. As is typical of many companies, the Company has experienced 
turnover of its sales force in the past, and there can be no assurance that 
the Company will be able to attract and retain adequate sales and marketing 
personnel. During 1997, the Company began evaluation of indirect distribution 
channels such as distributors, value-added resellers and systems integrators. 
The Company has selected two such organizations to work with and to expand 
access to its markets.  During 1997 these efforts did not generate material 
revenues.  The Company may expand such efforts in 1998, however, there can be 
no assurances that these channels will provide effective sales and marketing 
support for the Company. Failure to increase the Company's direct sales force 
or establish effective indirect sales channels could have a material adverse 
effect on the Company's business, operating results or financial condition. 

                                       13

DEPENDENCE ON FINANCIAL INDUSTRY; CHANGE IN DERIVATIVES AND RISK MANAGEMENT
MARKET, AND REGULATORY ENVIRONMENT

     Substantially all of the Company's current clients are domestic and 
international financial institutions. An economic downturn in the commercial 
and investment banking industries or in the level of derivatives trading 
could have a material adverse effect on the Company's business, operating 
results and financial condition. Any adverse change in the derivatives market 
affecting demand for the Company's products, whether by regulation, 
consolidation within the financial industry, negative publicity or otherwise, 
could have a material adverse effect on the Company's business, operating 
results and financial condition. 

     Derivative instruments have been involved in a number of well-publicized 
financial losses, including those involving Barings Bank and Orange County of 
California. Such losses have led to increasing governmental scrutiny and 
potential regulation of derivatives markets generally. Current legislative 
and regulatory measures reportedly being considered include additional 
reporting requirements pertaining to the current values of and risks 
associated with derivatives positions, and regulation of the mathematical 
models used to measure such values and risks. The Company believes that 
regulations which impose requirements of increased management controls or 
increased reporting may increase the demand for the Company's products. 
However, some legislators have questioned whether certain types of 
derivatives trading should be prohibited. Prohibitions on trading activities 
could reduce the size of the Company's markets. 

COMPETITION

     The market for financial risk management software is intensely 
competitive and is characterized by rapid technological change and frequent 
introduction of new products and features. The Company competes generally on 
the basis of product features and functions, product architecture, price, the 
speed and accuracy of the product processing capability, client service, the 
availability of sufficiently trained technical staff, and the vendor 
financial stability. In order to maintain or improve its position in this 
industry, the Company must continue to enhance its current products and 
develop new products in a timely fashion. There can be no assurance that the 
Company will succeed in this effort. 

     A major source of competition for the Company's products are 
applications that are internally developed by the financial institutions 
which are its potential clients, as well as institutions that are current 
clients. Even those financial institutions, including the Company's clients, 
that use the Company's products or other third-party software for some 
applications usually use internally developed software for the same or 
related applications. Many of these organizations have substantial internal 
development resources with the capability to develop specific products for 
their needs. Many of these organizations also value the ability to control 
the source code for their software systems. The Company does not typically 
make its source code available. There can be no assurance that the Company 
will successfully market its products to these organizations. 

     There are a significant number of independent commercial competitors for 
the Company's products. Some of these competitors, including SunGard Data 
Systems Inc., Infinity, Inc.,  and ACT Group plc., are larger than the 
Company and have longer operating histories and significantly greater 
financial, technical, sales and marketing and other resources, greater name 
recognition and a larger installed client base. 

TECHNOLOGICAL CHANGE

     The financial risk management software industry is characterized by rapid
technological advances, changes in client requirements and preferences, and
frequent new product introductions and enhancements. Historically, the Company
has released product enhancements at intervals of one to three years. The
Company's future success will depend, in significant part, upon its ability to
enhance its current products and to 

                                       14

<PAGE>

develop and market new products on a timely basis that keep pace with 
technological developments, respond to evolving client requirements and 
achieve market acceptance. In particular, the Company believes it must 
continue to respond quickly to users' needs for additional functionality and 
to advances in hardware and software platforms. Any failure by the Company to 
anticipate or respond adequately to technological developments and client 
requirements, or any significant delays or excessive costs in product 
development or introduction, could have a material adverse effect on the 
Company's operating results and financial condition. Because of the 
complexity of the Company's products, from time to time development efforts 
have taken longer than expected, causing delays in the release of new 
products and product enhancements, and this may occur again in the future. 
Any such delays could have a material adverse effect on the Company's 
business, operating results or financial condition. There can be no assurance 
that the Company will be successful in developing and marketing new products 
or product enhancements on a timely basis or that the Company will not 
experience significant delays or excessive costs in the future that could 
have a material adverse effect on the Company's operating results and 
financial condition. 

     Because the Company has limited resources, the Company must restrict its 
product development efforts and its porting efforts to a relatively small 
number of products and operating platforms. There can be no assurance that 
these efforts will be successful or, even if they are successful, that any 
resulting products or operating platforms will achieve market acceptance. 
Additionally, the Company offers standardized products designed for use 
worldwide. These products do not include general ledger systems or certain 
other product features tailored for specific regional markets or industry 
segments. The failure to include these features may adversely affect market 
acceptance of the Company's products. Furthermore, there can be no assurance 
that the cost of research and development efforts required to keep pace with 
technological changes will not have an adverse effect on the Company's 
business, operating results or financial condition. 

     New software products often contain undetected defects, or "bugs," that 
can adversely affect the performance of the product or otherwise disrupt a 
user's operations. If the Company's products contain material defects, client 
acceptance of such products could be adversely affected. Further, the Company 
could be subject to liability claims (for which it may not carry adequate 
insurance) that could have a material adverse effect on the Company's 
operating results and financial condition. 

LIMITED INTELLECTUAL PROPERTY PROTECTION 

     The Company's ability to compete effectively depends in large part on 
its ability to develop and maintain proprietary aspects of its technology. 
The Company relies on a combination of trade secret, copyright and trademark 
law, nondisclosure agreements and various measures including physical and 
logical access controls, to protect its proprietary rights in its software 
products. Despite these precautions it may be possible for unauthorized third 
parties to copy aspects of the Company's products or to obtain and use 
information that the Company regards as proprietary. Moreover, the laws of 
some foreign countries do not protect the Company's proprietary rights in its 
products to the same extent as do the laws of the United States. In addition, 
some aspects of the Company's products are not subject to intellectual 
property protection. 

     There can be no assurance that others may not independently develop the 
same or similar technology or otherwise obtain access to the Company's 
proprietary technology. In addition, the Company cannot be certain that 
others will not independently develop substantially equivalent or superseding 
proprietary technology, or that an equivalent product will not be marketed in 
competition with the Company's products, thereby substantially reducing the 
value of the Company's proprietary rights. There can be no assurance that any 
confidentiality agreements between the Company and its employees will provide 
adequate protection for the Company's proprietary information in the event of 
any unauthorized use or disclosure of such proprietary information.

                                       15

<PAGE>


     While the Company is not currently engaged in any intellectual property 
litigation or proceedings, there can be no assurance that the Company will 
not become involved in such proceedings. An adverse outcome in litigation or 
similar adversarial proceedings could subject the Company to significant 
liabilities to third parties, require disputed rights to be licensed from 
others or require the Company to cease the marketing or use of certain 
products, any of which could have a material adverse effect on the Company's 
business, financial condition and results of operations. The Company may be 
required to obtain licenses to patents or proprietary rights of others, and 
there can be no assurance that any licenses required under any patents or 
proprietary rights would be made available on terms acceptable to the 
Company, if at all. In January 1995, the Company received a letter claiming 
infringement of trademark with regard to its use of the C-atalyst name in the 
United Kingdom; however, although the Company does not believe that the 
outcome of the claim will have a material adverse effect on its business, 
there can be no assurance as to how the matter will be resolved. 

YEAR 2000 COMPLIANCE 

     The Company believes that all of its most current versions of its 
products will not cease to perform nor generate incorrect or ambiguous data 
or results due to a change in date on or after January 1, 2000, and will 
calculate any information dependent on such dates in the same manner, and 
with the same functionality, data integrity and performance, as such product 
do on or before December 31, 1999 (collectively, "Year 2000 Compliance").  
Year 2000 Compliance issues may arise with respect to any modifications made 
to the product by a party other than the Company or  from a combination or 
use of the Company's products with any other software programs or hardware 
device not provided by the Company and therefore may result in unforeseen 
Year 2000 Compliance problems for some of the Company's customers which may 
have an adverse effect on the Company. 

     Additionally, like any company with a computing infrastructure and 
utilizing business-application software programs written over many years, the 
Company's internal operations may be subject to year 2000 Compliance issues.  
The Company has been implementing enterprise wide information systems which 
support a majority of the Company's world-wide operations.  These systems are 
considered to currently be Year 2000 Compliant. Based solely due to a change 
in date to or after January 1, 2000 thereon, the Company believes that its 
internal operations will not be materially adversely impacted.

FUTURE ACQUISITIONS

     Future acquisitions by the Company may result in potentially dilutive 
issuances of equity securities, the incurrence of additional debt and 
amortization expenses related to goodwill and other intangible assets, which 
could adversely affect the Company's profitability.  For example, the Company 
acquired LOR/Geske Bock Associates, Inc. on February 13, 1996.  In addition, 
acquisitions involve numerous risks, including difficulties in the 
assimilation of the operations, products and personnel of the acquired 
company, the diversion of management's attention from other business 
concerns, risks of entering markets in which the Company has little or no 
direct prior experience, and the potential loss of key employees of the 
acquired company. The Company has, from time to time, engaged in discussions 
with a number of parties to acquire products complementary to its existing 
products, and may in the future pursue acquisitions of complementary 
products, technologies or businesses. While there are currently no 
commitments or agreements with respect to any acquisition, in the event that 
such an acquisition does occur, there can be no assurance as to the effect 
thereof on the Company's business, operating results or financial condition.

                  NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

                               DECEMBER 31, 1997

1.   NATURE OF OPERATIONS:

     C-ATS Software Inc. (the "Company") was organized in 1988 as a successor 
to a partnership formed in 1986. The Company develops and markets 
client/server software for financial risk management. The majority of the 
Company's current clients are domestic and international financial 
institutions.  On March 20, 1995, the Company completed an initial public 
offering of 1,300,000 shares of common stock at $12.00 per share.  Total 
proceeds to the Company (net of offering costs) were $13.8 million.

     On February 13, 1996, C-ATS Sub, Inc. (a wholly owned subsidiary of  the 
Company), merged with LOR/Geske Bock Associates, Inc. ("LORGB"), a California 
Corporation, pursuant to an "Agreement and Plan of Reorganization" dated 
January 30, 1996. LORGB designs, develops, and markets integrated, 
organization-wide market and credit risk management software systems. As a 
result of the merger, LORGB, Inc. ceased to exist  while C-ATS Sub continued 
as the surviving corporation.  The transaction was accounted for as a 
"purchase."  Accordingly, the operating results of the acquired business have 
been included in the consolidated statement of operations from the date of 
the acquisition (See Note 3). 

2.   SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES:

BASIS OF FINANCIAL STATEMENT PRESENTATION

     The accompanying consolidated financial statements include the accounts 
of the Company and its wholly owned subsidiaries. All significant 
intercompany balances and transactions have been eliminated. 

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

REVENUE RECOGNITION

     The Company licenses its products to end users under annual license 
agreements which include rights to maintenance support services and product 
upgrades. Accordingly, license revenues are recognized ratably over twelve 
months.   In addition, the Company provides training and consulting services 
to its clients. Revenue from such services is generally recognized as the 
services are performed. 

SOFTWARE DEVELOPMENT COSTS

     The Company capitalizes software development costs incurred after 
technological feasibility has been demonstrated.  To date, amounts that could 
have been capitalized have been immaterial and, therefore, no software 
development costs have been capitalized.

NET INCOME (LOSS) PER SHARE

     In 1997, the Company adopted Statement of Financial Accounting Standards 
("SFAS") No. 128 "Earnings per Share" ("SFAS No. 128"). SFAS No. 128 requires 
companies to complete net income or loss per share under two different 
methods, "basic" and "diluted".  "Basic" net income or loss per share for 
each period is calculated by dividing the net income or loss by the weighted 
average shares of common stock outstanding during the period.  Diluted net 
income or loss per share includes the impact of "potential" common shares 
from the exercise of stock options using the treasury stock method.

     As a result, 1996 and 1995 net income or loss per share has been 
restated to conform to the new standard.  "Potential" common shares included 
in the 1995 "diluted" earnings per share calculation consist of dilutive 
shares issuable upon the exercise of outstanding common stock. "Potential" 
common shares were not included in the 1997 and 1996 "diluted"  earnings per 
share calculation as the effects would be anti-dilutive.

     The following is a reconciliation of the weighted average common shares 
used to calculate Basic and Diluted net income or loss per share  for the 
years 1997, 1996, and 1995:

     Options to purchase 1,836,115, 1,374,394 and 46,740 shares of common 
stock at the weighted average prices of $4.10, $4.61 and $11.87 per share 
were outstanding during 1997, 1996 and 1995, respectively, but were not 
included in the computation of diluted net income or loss per share because 
the options' exercise prices were greater than the annual average market 
price of the common stock, and  would have an anti-dilutive effect on the net 
loss per share calculation.

CONCENTRATIONS OF CREDIT RISK

     Financial instruments which potentially subject the Company to 
concentrations of credit risk consist principally of cash investments, 
short-term investments and trade receivables. The Company has investment 
policies that limit most investments to short-term low risk instruments. 

     The Company provides credit, in the normal course of business to a 
limited number of financial institutions. The Company performs ongoing credit 
evaluations of its customers and maintains an allowance for potential credit 
risk.

CASH EQUIVALENTS AND MARKETABLE SECURITIES

     The Company considers all highly liquid investments including treasury 
bills and money market fund investments purchased with an original maturity 
of three months or less to be cash equivalents. 

     The Company classifies its investments pursuant to the provisions of 
Statement of Financial Accounting Standards No. 115, "Accounting for Certain 
Investments in Debt and Equity Securities".  Debt and marketable securities 
are classified in one of three categories: trading, available-for-sale, or 
held to maturity. The Company has no investment securities held for 
"trading".  Securities classified as "available-for-sale" are primarily 
investment grade municipal and corporate bonds, amounting to $16.4 million 
and $15.1 

                                       23

million as of December 31, 1997 and December 31, 1996, respectively, and 
recorded at fair value. Unrealized holding gains and losses, if any,  net of 
the related tax effect, are reported as a separate component of shareholders 
equity until realized. At December 31, 1997 and 1996, amortized cost was 
approximately equal to fair value for these securities.

FOREIGN CURRENCY TRANSLATION  

     The functional currency of foreign operations is deemed to be the local 
country's currency.  Consequently, assets and liabilities of the Company's 
foreign operations are translated at each balance sheet date into United 
States dollars using exchange rates in effect at that date in accordance with 
Statement of Financial Accounting Standards No. 52.  Income and expenses of 
the foreign operations are translated at average exchange rates for the 
period. Company revenues and corresponding receivables are typically U.S. 
dollar denominated and therefore are not impacted by translation adjustments. 
The effects of foreign currency translation adjustments are included as a 
component of shareholders' equity. 

PROPERTY AND EQUIPMENT

     Property and equipment are stated at cost. The cost of equipment and 
furniture and fixtures is depreciated using the straight-line method over the 
estimated useful lives of the assets, ranging from three to five years. 
Betterments, renewals and extraordinary repairs that extend the life of the 
asset are capitalized; other repairs and maintenance are expensed.  Leasehold 
improvements are amortized using the straight-line method over the lesser of 
the remaining term of the lease or the estimated economic life of the 
improvement.  The cost and accumulated depreciation applicable to assets 
retired are removed from the accounts and the gain or loss on disposition 
recognized in income. 

ACCOUNTING FOR STOCK BASED COMPENSATION

     The Company has two stock option plans which reserve shares of common 
stock for issuance to executives, key employees, consultants and directors.  
The Company accounts for stock-based compensation under the provisions of 
Accounting Board Opinion No. 25 "Accounting for Stock Issued to Employees" 
("APB 25").  The exercise price of options granted under these plans is equal 
to the market price of the Company's stock on the date of grant, and 
accordingly, no compensation cost is recorded under APB 25.  The Company has 
adopted the disclosure only provisions of Statement of Financial Accounting 
Standards No. 123 "Accounting for Stock-Based Compensation," effective 
January 1, 1996.  Note 5 of the Consolidated Financial Statements contains a 
summary of the pro forma effects to reported net income and earnings per 
share for 1997 and 1996 as if the Company had elected to recognize 
compensation expense based upon the fair value of the options granted at 
grant date as prescribed by SFAS No. 123.

RECLASSIFICATIONS

     Certain reclassifications have been made to 1996 and 1995 amounts to 
conform to the current year presentation.  These classifications did not 
change the previously reported net income/(loss), total assets or total cash 
flows of the Company for those years.

NEW ACCOUNTING STANDARDS

     In 1997, the Company adopted Statement of Financial Accounting Standards 
("SFAS") No. 129, "Disclosure of Information About Capital Structure."  SFAS 
No. 129 requires companies to disclose certain information about their 
capital structure. SFAS No. 129 did not have a material impact on the 
Company's consolidated financial statement disclosures.

     In 1997, the Financial Accounting Standards Board ("FASB") issued SFAS 
No. 130, "Reporting Comprehensive Income," which will be adopted by the 
Company in the first quarter of 1998. SFAS No. 130 requires companies to 
report a new, additional measure of income on the income statement or to 
create a new financial statement that has the new measure of income on it. 
"Comprehensive Income" is to include foreign currency translation gains and 
losses and other unrealized gains and losses that have been previously 
excluded from net income or loss and reflected instead in equity.  The 
Company anticipates that SFAS No.130 will not have a material impact on the 
Company's consolidated financial statements.

     In 1997, the FASB issued SFAS No. 131, "Disclosures about Segments of an 
Enterprise and Related Information," which will be adopted by the Company in 
the 1998 annual consolidated financial statements. SFAS No. 131 requires 
companies to report financial and descriptive information about its 
reportable operating segments, including segment profit or loss, certain 
specific revenue and expense items and segment assets as well as information 
about revenues derived from the Company's products and services, the 
countries in which the Company earns revenues and holds assets and major 
customers.  The Company currently provides much of this information in its 
current consolidated  financial statements and anticipates that SFAS No. 131 
will not have a material impact on the Company's consolidated financial 
statements.

     In 1997, the Accounting Standards Executive Committee of the American 
Institute of Certified Public Accountants issued Statement of Position 
("SOP") 97-2, "Software Revenue Recognition," which will be adopted by the 
Company in the first quarter of 1998.  SOP 97-2 provides guidance on applying 
generally accepted accounting principles in recognizing revenue on software 
transactions. The Company anticipates that SOP 97-2 will not have a material 
impact on the Company's consolidated financial statements.

3.   ACQUISITIONS:

     On February 13, 1996, the Company completed the acquisition of all the 
outstanding common stock of LORGB.  The purchase price of approximately $8.2 
million included an issuance of 578,651 shares of the Company's common stock, 
approximately $3.3 million in cash and the assumption of options to purchase 
approximately 167,000 shares of the Company's common stock.  The acquisition 
has been recorded using the purchase method of accounting.  The aggregate 
purchase price has been allocated to the acquired assets and liabilities of 
LORGB, of which the net tangible assets were not significant.  The allocation 
resulted in $8,044,000 allocated to purchased technology, $7,066,000 of which 
represented in process research and development.  The $7,066,000 was expensed 
in the accompanying statements of operations as the technology had not yet 
reached technological feasibility and does not have alternative future uses.  
The capitalized amount of $977,000 is included in "Purchased software" in the 
accompanying balance sheets and is amortized over four years.

options were granted under this plan at an exercise price of $8.00 per share. 
Options must be issued at the fair market value of the Company's common stock 
at date of grant, have a term of ten years and vest 33% each year following 
the date of grant.  At December 31, 1997, options to purchase 60,000 shares 
were exercisable at $8.00 per share under the 1995 Director Option Plan.  
During 1997, options to purchase 20,000 shares were canceled under the 
Director Option Plan.

OPTION FAIR VALUE

     The Company has adopted Statement of Financial Accounting Standards 
("SFAS") No. 123, "Accounting for Stock-Based Compensation," issued in 
October 1995.  In accordance with the provisions of  SFAS No. 123, the 
Company applies Opinion 25 and related interpretations in accounting for its 
stock option plans and, accordingly, does not recognize compensation cost as 
the exercise price equals the fair value of common stock at the date of 
grant.  If the Company had elected to recognize compensation cost based on 
the fair value of the options granted at grant date as prescribed by SFAS No. 
123, net income (loss) and income (loss) per share would have been changed to 
the pro forma amounts indicated in the table below.

     The fair value of each grant is estimated on the date of grant using the 
Black-Scholes option pricing model with the following assumptions:  a 
weighted average risk-free interest rate of 5.80% corresponding to government 
securities with original maturities similar to the estimated option life of 
approximately one year beyond vest date;  annual volatility of the Company's 
stock price of 65%; and a dividend yield of 0.0%.  The effects of applying 
the provisions of SFAS No. 123 are not likely to be representative of the 
effects on the pro forma net income (loss) in future years.  The weighted 
average of fair values of options granted during 1997 and 1996 were 
approximately $2.34 for both years.  The options outstanding and exercisable 
under all option plans are as follows:

6.  INCOME TAXES:

     The Company accounts for income taxes in accordance with Statement of 
Financial Accounting Standards No. 109, "Accounting for Income Taxes." This 
statement provides for a liability approach under which deferred income taxes 
are provided based upon enacted tax laws and rates applicable to the periods 
in which the taxes become payable. 

     The provision for income taxes consisted of the following components for 
the years ended December 31 (in thousands):

</TABLE>

     For income tax reporting purposes, the Company has Federal and State net 
operating loss carryforwards of approximately $2,500,000 and $1,000,000, 
respectively, and Federal and State research and development tax credit 
carryforwards of approximately $110,000 and $124,000, respectively, all of 
which will expire on various dates through 2012.  The Internal Revenue Code 
contains provisions which may limit the amount of tax carryforwards available 
to be used in any given year upon the occurrence of certain events, including 
changes in ownership interests.  Due to certain limitations of the benefits 
related to tax carrybacks, the current year operating loss and the 
uncertainty of future results, the Company has provided a valuation allowance 
related to a portion of the deferred tax asset. 

     The Company's tax returns for 1990 through 1993 are currently being 
examined by the Internal Revenue Service ("IRS") which has issued a notice of 
assessment related to its position on foreign tax credits related to foreign 
withholding taxes on the Company's software license revenue. If the IRS 
position were to prevail in full, the net tax cost for this assessment at 
December 31, 1997 would be approximately $2.3 million, excluding interest and 
penalties. The Company is currently seeking competent authority relief, 
which, if successful, will eliminate any potential double taxation.  In 
management's opinion the ultimate resolution of this matter will not have a 
material adverse effect on the results of operations.

7.   WORLDWIDE OPERATIONS:

     The Company operates in a single industry segment and has wholly-owned 
foreign subsidiaries in the United Kingdom and Switzerland that conduct sales 
representative activities in Europe and a wholly-owned subsidiary that 
conducts sales representative activities in Japan. All license agreements are 
entered into between the parent company and the clients, and all license and 
service fees are paid directly to the parent company in U.S. dollars. United 
States operations include revenue and results of operations in the United 
States as well as export revenue from all clients recognized on a worldwide 
basis. Subsidiary revenues consist solely of payments from the parent company 
for services performed for the benefit of the parent company at a rate of 
cost plus 10%. Such transfers are eliminated in the consolidated financial 
statements. Identifiable assets are those assets that can be directly 
associated with a particular geographic area and subsidiary. The Company's 
operations by geographic area were as follows (in thousands):

<F1>In the fiscal year ended December 31, 1997 common share equivalents, if
included, would have an anti-dilutive effect on the net loss per share
calculation and are therefore excluded from the fully diluted calculation.
If included, the net loss per share would be $0.36 per share.
