   Prior to this Offering, there has been no public market for the Common

Nasdaq SmallCap Market ("NASDAQ") under the proposed symbol "THNK" and for 
listing of the Common Stock on the Boston Stock Exchange ("BSE") and the 
Pacific Stock Exchange ("PSE") under the proposed symbol TTI. It is currently 
anticipated that the initial public offering price will be between $6.00 and 
$8.00 per share. The initial public offering price of the Common Stock has 
been determined by negotiations between the Company and Barington Capital 
Group, L.P. (the "Underwriter"). See "Underwriting" for information relating 
to the factors considered in determining the initial public offering price. 

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

All references to "Thinking Tools" or the "Company" contained in this 
Prospectus refer to Thinking Tools, Inc., a Delaware corporation, and its 
predecessor. Unless otherwise stated, all information contained in this 
Prospectus assumes that the Over-Allotment Option has not been exercised. 
This Prospectus contains forward-looking statements that involve risks and 
uncertainties. The Company's actual results may differ significantly from the 
results discussed in the forward-looking statements. Factors that might cause 
such differences include, but are not limited to, those discussed in "Risk 
Factors." The Shares offered hereby involve a high degree of risk. Investors 
should carefully consider the information set forth under "Risk Factors." 

                              PROSPECTUS SUMMARY 

   The following summary information is qualified in its entirety by the more 
detailed information and financial statements, including the notes thereto, 
appearing elsewhere in this Prospectus and, accordingly, should be read in 
conjunction with such information, financial statements and notes. Each 
prospective investor is urged to read this Prospectus in its entirety. 

                                 THE COMPANY 

   Thinking Tools develops powerful and flexible PC-based business simulation 
software programs that enable users to simulate real life business 
situations, explore complex operational problems and improve functional and 
problem solving skills. The Company's agent-based, adaptive simulation 
software has a broad range of potential business applications, including 
strategic planning, sales and marketing, training, competitive positioning, 
product marketing, operational planning, logistics and supply and demand 
forecasting. The Company believes that its products are unique because they 
combine user-friendly interactive interfaces used in sophisticated computer 
games with its proprietary agent-based programming to produce interactive 
adaptive business simulations. Agent-based, adaptive simulations can be used 
to model competitive situations, simulate consumer behavior, demonstrate the 
impact of management actions, seek system vulnerabilities and explore complex 
operational systems. The Company's user-friendly interfaces enable persons 
with no technical training to comfortably interact with complex systems. 

   The Company's agent-based programming enables autonomous agents in the 
simulation to respond to user behaviors in unpredictable and realistic ways. 
In contrast to other modelling and simulation tools in use and known to the 
Company, which are generally built around a limited number of agents acting 
according to pre-programmed, deterministic algorithms, the multiplicity of 
autonomous agents and the results of their interactions with each other and 
the user give the Company's simulations a complexity that mirrors human 
behavior found in the real world. 

   The Company's operations to date have primarily involved developing 
complex business simulation software programs for specific customers. These 
projects have helped to fund the Company's research and development efforts, 
led to the validation of the Company's core technology by major U.S. 
companies and demonstrated the potential market for business simulation 
software of the type developed by the Company. 

   The Company's goal is to develop and own the rights to a variety of 
simulations in divergent business areas. The Company believes that it is 
well-positioned to expand its business by leveraging its existing products 
and technology platform to become a product-oriented, sales-driven company. 
As part of its growth strategy, the Company intends to begin self-funded 
development of new simulations and adaptation of previously developed 
simulations for wider distribution or application to new fields. The Company 
also plans, upon request, to customize these packages for specific customers. 
The Company is currently developing software to simulate disaster recovery 
scenarios, logistics simulation software for planning and training in the 
United States Army and United States Air Force and software that could 
provide access to simulations being developed by the Company for use on the 
internet. The Company intends to market its products through existing 
channels of its strategic partners as well as directly to customers by 
establishing an in-house sales force and through value added resellers. 

                                      3

   Some of the Company's products developed to date include SimRefinery, 
SimHealth, TeleSim and Project Challenge. SimRefinery, a demonstration 
program released in late 1992, which was developed for Chevron, Inc., 
simulates the effects of users' decisions made in the running of a refinery. 
SimHealth, a simulation of the impact of various proposed reforms on the 
United States health care system, simulates both the supply and demand sides 
of the health care industry and the impact of choices and values on the 
financial health of the system and its usage and demand. TeleSim, a 
simulation of a local exchange telephone market, was developed by the Company 
for Coopers & Lybrand L.L.P ("Coopers"). Since its initial development in 
1994, versions of TeleSim have been produced and sold through Coopers to 
Sprint Corp., NYNEX Corporation, Pacific Telecom, Inc. and AT&T Corp. Project 
Challenge, the development of which is being funded by SHL SystemHouse, Inc., 
a division of MCI Communications Corp. ("SystemHouse"), focuses on project 
management for information systems projects. Project Challenge users create a 
model of their projects, then simulate management of the projects under 
benign, realistic or hostile conditions. Other customers of the Company have 
included Xerox Corp., Andersen Consulting L.L.P., Texas Instruments 
Corporation, Harcourt Brace College Publishers, a division of Harcourt 
General, Inc., Steelcase Inc. and System Engineering Solutions Inc. (a prime 
contractor for work in logistics for the U.S. Army and U.S. Air Force). 

   The Company's capabilities in developing highly sophisticated simulations 
are built upon experience gained from developing computer games, its skill in 
programming autonomous and adaptive agents and its large and growing library 
of reusable simulation objects. The Company's creative control is based on 
its proprietary development environment, WHITEBOARD, which supports interface 
building, object creation, simulation management, object management and 
application frameworks. WHITEBOARD simplifies and supports the construction 
of agent-based simulations and is the core of the development of each of the 
Company's simulations. 

   The Company was formed to purchase, on December 31, 1993, certain assets 
of the Business Simulation Division (the "Division") of Maxis, Inc. 
("Maxis"), a leading computer game company and creator of the simulation game 
SimCity(tm). Through the purchase agreement with Maxis, the Company acquired 
the Division's equipment, staff, work-in-progress, customers, licenses, 
prospects, software tools, libraries and processes (the "Acquisition"). 

   The Company's predecessor was incorporated in California on December 30, 
1993. The Company was re-incorporated in Delaware on August 8, 1996, and its 
principal place of business is located at One Lower Ragsdale Drive, I-250, 
Monterey, California 93940, at (408) 373-8666.

INFORMATION CONTAINED IN THIS PROSPECTUS AND SHOULD GIVE PARTICULAR 
CONSIDERATION TO THE FOLLOWING RISK FACTORS BEFORE DECIDING TO PURCHASE THE 
COMMON STOCK OFFERED HEREBY. 

Limited Operating History; History of Losses; Uncertain Future Profitability. 

   The Company commenced operations in January 1994 and is still in the early 
stage of developing products. Since its inception, the Company has 
experienced cumulative losses of $1,650,000 and $1,997,000 as of December 31, 
1995 and June 30, 1996, respectively, and has not experienced any quarter of 
profitable operations. Consequently, its operations are subject to numerous 
risks associated with the development of a new business. The Company expects 
to continue to incur operating losses for the foreseeable future, principally 
as a result of expenses associated with the Company's product development 
efforts and anticipated sales, marketing and general and administrative 
expenses. The Company's long-term viability and growth will depend on the 
successful development, commercialization and marketing of its proposed 
products. There can be no assurance that the Company will be able to develop 
adequate revenue sources to successfully complete the development, 
commercializing and marketing of its proposed products or that if it is 
successful in doing so it will be able to achieve and maintain profitability. 
See "Management's Discussion and Analysis of Financial Condition and Results 
of Operations." 

Dependence on Emerging Market for Business Simulation Software. 

   The markets for business simulation software in general, and agent-based, 
adaptive simulation software in particular, are still emerging, making it 
difficult to predict with any assurance the future size of the markets. There 
can be no assurance that such software will achieve broad-based market 
acceptance, that markets for such software will continue to grow or that 
increased sales of the Company's products will occur or continue as a result 
of any such growth. There can be no assurance that alternatives to the 
Company's agent-based, adaptive simulation software, such as object-oriented 
tools, authoring tools or game methods will not achieve greater market 
acceptance than the Company's agent-based, adaptive simulation software. Even 
if agent-based, adaptive simulation achieves market acceptance and that 
market grows, there can be no assurance that the Company will obtain a 
significant share of that market. See "Business--Growth Strategy" and 
"--Competition." 

Uncertainties Related to Development of Additional Products. 

   Significant additional efforts will be required for the Company to develop 
additional agent-based, adaptive simulation products. Any such future efforts 
are subject to certain risks including, but not limited to, the risk that new 
simulations will be difficult to develop into commercially viable products 
free of 

                                      8 

<PAGE>
 
competitive challenges and that any such products may fail to achieve and 
sustain market acceptance. There can be no assurance that the Company's 
product development efforts will be successful. See "Business -- Growth 
Strategy" and "--Products." 

Limited Marketing Experience; Need for Additional Personnel. 

   The Company has very limited marketing resources and limited experience in 
marketing and selling its products and services. The Company will have to 
further develop its marketing and sales force or rely principally on 
value-added resellers, collaborators, licensees or others to provide for the 
marketing and sales of its products and services. There can be no assurance 
that the Company will be able to establish adequate marketing and sales 
capabilities or make arrangements with value-added resellers, collaborators, 
licensees or others to perform such activities. Achieving market penetration 
will require significant efforts by the Company to create awareness of, and 
demand for, its proposed products. Accordingly, the Company's ability to 
expand its customer base will depend upon its marketing efforts, including 
its ability to establish an effective internal sales organization or 
establish strategic marketing arrangements with others. The failure by the 
Company to successfully develop its marketing capabilities, internally or 
through others, would have a material adverse effect on the Company's 
business, financial condition and results of operations. Further, there can 
be no assurance that the development of such marketing capabilities will lead 
to sales of the Company's proposed products. See "Business--Personnel." 

   The success of the Company will also depend upon its ability to hire and 
retain additional qualified management, marketing and financial personnel, 
including a chief executive officer and a chief financial officer, as to 
which there can be no assurance. The Company will compete with other 
companies with greater financial and other resources for such personnel. See 
"Management." 

Risks Associated with Growth Strategy. 

   The Company's growth strategy is expected to place a significant strain on 
its management, administrative, operational, financial and other resources. 
The Company's success will be dependent upon its ability to hire additional 
highly qualified personnel to support the Company's product development and 
marketing efforts, including monitoring operations, controlling costs and 
maintaining effective management, inventory and credit controls. The Company 
has limited experience in effectuating rapid expansion and managing a broad 
range of products and services and significant operations. There can be no 
assurance that the Company will be able to continue to manage its operations 
or that any inability to do so will not adversely affect its business, 
financial condition or results of operations. See "Business--Growth 
Strategy." 

Anticipated Non-Cash Charges. 

   As a result of the issuance of warrants in connection with borrowings from 
Technologies and pursuant to the Bridge Financing, the Company anticipates 
that it will record approximately $900,000 of non-cash interest expenses. 
These expenses are anticipated to be incurred in the third and fourth quarter 
of 1996. The Company also expects to incur approximately $200,000 of non-cash 
compensation expense related to the difference between the exercise price and 
deemed fair value of the Common Stock underlying vested options granted in 
July and August 1996. See "Note 10" and "Note 13" to "Notes to Financial 
Statements." 

Fluctuations in Operating Results; Substantial Revenues Derived from Limited 
Customers. 

   The Company's operating results may vary significantly from quarter to 
quarter or year to year, depending on factors such as the timing of product 
development, the timing of increased research and development and sales and 
marketing expenses, the timing and size of orders and the introduction of new 
products by the Company. The Company's current and planned expense levels are 
based in part on its 

                                      9 

<PAGE>

expectations as to future revenue. Consequently, revenue or profit may vary 
significantly from quarter to quarter or year to year and revenue or profit 
in any period will not necessarily be predictive of results in subsequent 
periods. Historically, a significant portion of the Company's revenues have 
been derived from a limited number of relatively large development projects 
contracted for by a small number of customers. To the extent that the 
Company's business continues to be derived from a limited number of large 
customer orders, any inability by the Company as it completes such orders to 
obtain new orders could have a material adverse effect on the Company's 
business, financial condition and results of operations. The Company is 
currently working on a limited number of customer orders. There can be no 
assurance that the Company will obtain additional sources of revenue prior to 
completing such projects. See "Management's Discussion and Analysis of 
Financial Condition and Results of Operations." 



Technological Change; Risk of Obsolescence; Industry Standards. 

   The software industry is characterized by rapid technological change, 
frequent introductions of new products, changes in customer demands and 
evolving industry standards. The introduction of products embodying new 
technology or the adaption of products to the market and the emergence of new 
industry standards often render existing products obsolete and unmarketable. 
The Company believes that its success will depend on its ability to enhance 
its existing products and otherwise respond and keep pace with technological 
developments and emerging industry standards. There can be no assurance that 
the Company will be successful in developing enhanced or new products that 
respond to technological changes or evolving industry standards in a timely 
manner, or at all. Additionally, there can be no assurance that technological 
changes or evolving industry standards will not render the Company's products 
and technologies obsolete. See "Business--Intellectual Property." 

Uncertainties Regarding Intellectual Property. 

   The Company does not have any patents and has not filed patent 
applications on its products. The Company regards the software that it owns 
or licenses as proprietary and relies primarily on a combination of trade 
secret laws, nondisclosure agreements and other technical copy protection 
methods (such as embedded coding) to protect its rights to its products and 
proprietary rights. It is the Company's policy that all employees and 
third-party developers sign nondisclosure agreements; however, this may not 
afford the Company sufficient protection for its know-how and its proprietary 
products. Other parties may develop similar know-how and products, duplicate 
the Company's know-how and products or develop patents that would materially 
and adversely affect the Company's business, financial condition and results 
of operations. Third parties may assert infringement claims against the 
Company, and such claims may result in the Company being required to enter 
into royalty arrangements, pay damages or defend litigation, any of which 
could materially and adversely affect the Company's business, financial 
condition and results of operations. See "Business--Intellectual Property." 

Competition. 

   There can be no assurance that other companies will not develop programs 
such as those offered by the Company or alternative software applications 
which meet the same needs of customers or that potential customers will not 
choose to meet their needs through in-house development rather than by 
purchasing the Company's products. The Company expects to be subject to 
competition from companies with substantially greater resources. There can be 
no assurance that the Company will be able to respond to competitive 
pressures, or that the effect of competitive pressures will not change the 
demand for, or pricing of, the Company's products and services. To the extent 
that competitors achieve performance, price or other selling advantages, the 
Company could be adversely affected. There can be no assurance that the 
Company will have the resources required to respond effectively to market or 
technological changes or to otherwise compete successfully in the future. See 
"Business--Competition." 

                                      10 

<PAGE>

Dependence on Key Personnel. 

   The Company is dependent upon the continued efforts and abilities of its 
senior management, particularly those of Mr. John Hiles, the Company's 
President. The loss or unavailability of Mr. Hiles for any significant period 
could have a material adverse effect on the Company's business, financial 
condition and results of operations. The Company maintains a $5,000,000 
key-man life insurance policy on Mr. Hiles. The Company's operations are also 
dependent upon its ability to attract and retain qualified programmers and 
software engineers. There can be no assurance that the Company will be able 
to attract and retain such skilled personnel, and failure to do so could have 
a material adverse effect on the business, financial condition and results of 
operations of the Company. All employees of the Company are at-will 
employees. See "Management." 

Control by Existing Stockholders. 

   Upon the closing of this Offering, the Company's existing stockholders 
will beneficially own approximately 72.8% of the outstanding shares of Common 
Stock. As a result of such ownership, the existing stockholders of the 
Company will, therefore, have the ability to control the election of the 
directors of the Company and the outcome of all issues submitted to a vote of 
the stockholders of the Company. See "Principal Stockholders." 

Broad Discretion as to Use of Proceeds. 

   Approximately 20.8% of the net proceeds of this Offering has been 
allocated to working capital and general corporate purposes and will be used 
for such specific purposes as management may determine. Accordingly, 
management will have broad discretion with respect to the expenditure of that 
portion of the net proceeds of this Offering. In addition, the Company's 
estimate of its allocation of the use of proceeds of this Offering is subject 
to a reapportionment of proceeds among the categories set forth herein or to 
new categories. The amount and timing of expenditures will vary depending 
upon a number of factors, including the progress of the Company's product 
development and marketing efforts, changing competitive conditions and 
general economic conditions. See "Use of Proceeds." 

Need For Additional Financing. 

   The Company anticipates that the net proceeds of this Offering together 
with its existing resources, will be adequate to satisfy its operating and 
capital requirements through at least the next 18 months, based on the 
Company's current business plan. Such belief is based upon certain 
assumptions, and there can be no assurance that such assumptions are correct. 
However, the Company does not expect that it will be able to continue its 
operations beyond this time without additional financing. There can be no 
assurance that such additional financing will be available when needed on 
terms acceptable to the Company or at all. See "Management's Discussion and 
Analysis of Financial Condition and Results of Operations." 

Absence of Public Market; Negotiated Offering Price. 

   Prior to this Offering, there has been no public market for the Common 
Stock, and there can be no assurance that any trading market therefor will 
develop or, if any such market develops, that it will be sustained. 
Accordingly, purchasers of the Shares may experience difficulty selling or 
otherwise disposing of their Shares. The public offering price of the Shares 
has been established by negotiation between the Company and the Underwriter 
and does not bear any relationship to the Company's book value, assets, past 
operating results, financial condition or other established criteria of 
value. 

                                      11 

<PAGE>

NASDAQ, BSE and PSE Delisting; Low Stock Price. 

   The trading of the Company's Securities on NASDAQ, BSE and PSE will be 
conditioned upon the Company meeting certain asset, capital and surplus 
earnings and stock price tests set forth by such exchanges. For example, to 
maintain eligibility for trading on NASDAQ, the Company will be required to 
maintain total assets in excess of $2,000,000, capital and surplus in excess 
of $1,000,000 and (subject to certain exceptions) a bid price of $1.00 per 
share. Upon completion of this Offering and the receipt of the proceeds 
therefrom, the Company believes that it will meet the respective asset, 
capital and surplus earnings tests set forth by such exchanges. If the 
Company fails any of the tests, the Common Stock may be delisted from trading 
on such exchanges. The effects of delisting include the limited release of 
the market prices of the Company's securities and limited news coverage of 
the Company. Delisting may restrict investors' interest in the Company's 
securities and materially adversely affect the trading market and prices for 
such securities and the Company's ability to issue additional securities or 
to secure additional financing. In addition to the risk of volatile stock 
prices and possible delisting, low price stocks are subject to the additional 
risks of federal and state regulatory requirements and the potential loss of 
effective trading markets. In particular, if the Common Stock were delisted 
from trading on such exchanges and the trading price of the Common Stock was 
less than $5 per share, the Common Stock could be subject to Rule 15g-9 under 
the Securities Exchange Act of 1934, as amended, which, among other things, 
requires that broker/dealers satisfy special sales practice requirements, 
including making individualized written suitability determinations and 
receiving purchasers' written consent, prior to any transaction. If the 
Company's securities could also be deemed penny stocks under the Securities 
Enforcement and Penny Stock Reform Act of 1990, this would require additional 
disclosure in connection with trades in the Company's securities, including 
the delivery of a disclosure schedule explaining the nature and risks of the 
penny stock market. Such requirements could severely limit the liquidity of 
the Company's securities and the ability of purchasers in this Offering to 
sell their securities in the secondary market. 

Future Sales of Restricted Securities. 

   Upon the completion of this Offering, the Company will have 4,431,758 
shares of Common Stock outstanding (4,641,758, if the Over-Allotment Option 
is exercised in full). Of these shares, all of the 1,400,000 shares of Common 
Stock sold in this Offering (1,610,000, if the Over-Allotment Option is 
exercised in full) generally will be freely transferable by persons other 
than affiliates of the Company, without restriction or further registration 
under the Securities Act of 1933, as amended (the "Securities Act"). The 
remaining 3,031,758 shares of Common Stock (the "Restricted Shares") 
outstanding were sold by the Company in reliance on exemptions from the 
registration requirements of the Securities Act and are "restricted 
securities" as defined in Rule 144 under the Securities Act. The sale of a 
substantial number of shares of Common Stock or the availability of Common 
Stock for sale could adversely affect the market price of the Common Stock 
prevailing from time to time. The Company, its officers, directors and 
existing stockholders have entered into agreements which prohibit them from 
selling stock in the Company for certain periods of time following this 
Offering. See "Principal Stockholders," "Shares Eligible for Future Sale" and 
"Underwriting." 

Effect of Previously Issued Options, Warrants and Underwriter's Options on 
Stock Price. 

   The Company has reserved from the authorized, but unissued, Common Stock 
376,000 shares of Common Stock for issuance to key employees, officers, 
directors, and consultants pursuant to the Plan, has reserved 456,250 shares 
of Common Stock for issuance upon exercise of the Bridge Warrants and 468,242 
shares of Common Stock issuable upon exercise of the Technologies Warrants. 
The Company will also sell to the Underwriter, in connection with this 
Offering, for nominal consideration, the Underwriter's Options to purchase an 
aggregate of 140,000 shares of Common Stock at a price per share equal to 
120% of the initial public offering price per share, subject to adjustment as 
provided therein. The existence of the Bridge Warrants, the Technologies 
Warrants, the Underwriter's Options, any outstanding options issued under the 
Plan, and other options or warrants may prove to be a hindrance to future 
financings, since the 

                                      12 

<PAGE>

holders of such warrants and options may be expected to exercise them at a 
time when the Company would otherwise be able to obtain additional equity 
capital on terms more favorable to the Company. In addition, the holders of 
such securities have certain registration rights, and the sale of the shares 
issuable upon exercise of such securities or the availability of such shares 
for sale could adversely affect the market price of the Common Stock. 
Additionally, if the holders of the Underwriter's Options were to exercise 
their registration rights to effect a distribution of the Underwriter's 
Options or underlying securities, the Underwriter, prior to and during such 
distribution, would be unable to make a market in the Company's securities 
and would be required to comply with other limitations on trading set forth 
in Rules 10b-2, 10b-6 and 10b-7 promulgated under the Securities Exchange Act 
of 1934, as amended. Such rules restrict the solicitation of purchasers of a 
security when a person is interested in the distribution of such security and 
also limit market making activities by an interested person until the 
completion of the distribution. If the Underwriter were required to cease 
making a market, the market and market price for such securities may be 
adversely affected and holders of such securities may be unable to sell such 
securities. See "Description of Securities" and "Underwriting." 

Share Prices May Be Highly Volatile. 

   The market prices of equity securities of computer technology and software 
companies have experienced extreme price volatility in recent years for 
reasons not necessarily related to the individual performance of specific 
companies. Accordingly, the market price of the Common Stock following this 
Offering may be highly volatile. Factors such as announcements by the Company 
or its competitors concerning products, patents, technology, governmental 
regulatory actions, other events affecting computer technology and software 
companies generally as well as general market conditions may have a 
significant impact on the market price of the Common Stock and could cause it 
to fluctuate substantially. 

Dilution. 

   The assumed initial public offering price per Share exceeds the book value 
per share of the Common Stock. Investors in this Offering will therefore 
incur immediate and substantial dilution of $5.39, or 77% per share from the 
initial public offering price. See "Dilution." 

Lack of Dividends. 

   The Company has not paid any dividends on the Common Stock since its 
inception and does not intend to pay any dividends to its stockholders in the 
foreseeable future. The Company currently intends to reinvest earnings, if 
any, in the development and expansion of its business. See "Dividend Policy" 
and "Description of Securities--Common Stock." 

Anti-Takeover Effects of Certain Provisions of Certificate of Incorporation 
and Delaware Law. 

   The Company's Certificate of Incorporation authorized the issuance of 
3,000,000 shares of undesignated Preferred Stock with such designations, 
rights and preferences as may be determined from time to time by the board of 
directors. Accordingly, the board of directors is empowered, without 
obtaining stockholder approval, to issue such Preferred Stock with dividend, 
liquidation, conversion, voting or other rights that could adversely affect 
the voting power or other rights of the holders of the Common Stock. In the 
event of issuance, the Preferred Stock could be utilized, under certain 
circumstances, as a method of discouraging, delaying or preventing a change 
in the control of the Company. Certain provisions of Delaware law may also 
discourage third party attempts to acquire control of the Company. See 
"Description of Securities--Preferred Stock."

                                USE OF PROCEEDS

   The net proceeds from the sale of the Common Stock offered hereby, at an 
assumed initial offering price of $7.00 per share, and after deducting 
underwriting discounts and commissions and other expenses of this Offering, 
estimated to be, in the aggregate, $1,774,000, are estimated to be $8,026,000 
($9,304,900 if the Over-Allotment Option is exercised in full). 


   The Company intends to use the net proceeds of this Offering (i) to fund 
the Company's sales and marketing efforts, (ii) to fund the Company's product 
development efforts, (iii) to fund the retirement of the Bridge Notes and 
(iv) for working capital and general corporate purposes, approximately as 
follows:

   The Company intends to use approximately $3,000,000 of the net proceeds to 
fund expansion of its sales and marketing activities, including hiring a 
senior sales and marketing executive, sales representatives and other sales 
and marketing personnel. See "Business--Marketing and Sales Strategy." 

   The Company intends to use approximately $1,500,000 of the net proceeds 
for research and product development, including support of existing research 
and development activities and the development of new products. See 
"Business--Product Development." 

   Approximately $1,855,000 of the net proceeds will be used to repay the 
principal amount of the Bridge Notes, along with estimated accrued interest 
thereon through the estimated closing date of this Offering. The Bridge Notes 
bear interest at a rate of 10% per annum, compounded annually, and are due 
upon the closing of this Offering. The Bridge Notes were sold as units along 
with the Bridge Warrants in the Bridge Financing. The Company utilized a 
portion of the net proceeds from the Bridge Financing (with related expenses 
of approximately $258,000) to repay $625,000 of outstanding indebtedness to 
Technologies, which amount was immediately utilized by Technologies for the 
purchase of $625,000 aggregate principal amount of Bridge Notes in the Bridge 
Financing. As a result, the Company realized approximately $942,000 of net 
proceeds from the Bridge Financing, which funds are being used to finance the 
Company's short term working capital needs and to fund expenses of the 
Company in connection with this Offering. See "Certain Transactions." 

   The balance of the net proceeds of this Offering are intended to be used 
for general corporate and working capital purposes. Any net proceeds received 
by the Company from the exercise of the Over- Allotment Option or the 
Underwriter's Options will be added to working capital. 

   The foregoing represents the Company's best estimate of its allocation of 
the estimated net proceeds of this Offering and is subject to a 
reapportionment of proceeds among the categories listed above or to new 
categories in response to, among other things, changes in its plans, 
regulations, industry conditions, and future revenues and expenditures. The 
amount and timing of expenditures will vary depending on a number of factors, 
including changes in the Company's contemplated operations or business plan 
and changes in economic and industry conditions. 

   Until used, the Company intends to invest the net proceeds of this 
Offering in short term, interest bearing, investment grade, debt securities, 
money market accounts, certificates of deposit or direct or guaranteed 
obligations of the United States government.

                                DIVIDEND POLICY

   The Company expects that it will retain all earnings, if any, generated by 
its operations for the development and growth of its business and does not 
anticipate paying any cash dividends to its stockholders in the foreseeable 
future. Any future determination as to dividend policy will be made by the 
board of directors of the Company in its discretion, and will depend on a 
number of factors, including the future earnings, if any, capital 
requirements, financial condition and business prospects of the Company and 
such other factors as the board of directors may deem relevant. See "Risk 
Factors--Lack of Dividends." 

                                   DILUTION 

   As of June 30, 1996, the Company had a pro forma net tangible book value 
(deficit) of approximately ($876,000), or ($0.29) per share of Common Stock. 
Without taking into account any other changes in the pro forma net tangible 
book value of the Company after June 30, 1996, other than to give effect to 
the sale by the Company of the Shares offered hereby at an assumed initial 
offering price of $7.00 per share and the receipt and application of the 
estimated net proceeds therefrom (including repayment of the Bridge Notes and 
accrued cash interest thereon), the pro forma net tangible book value would 
have been approximately $7,121,000, or $1.61 per share, which represents an 
immediate increase in the pro forma net tangible book value of $1.90 per 
share to present stockholders and an immediate dilution of $5.39 per share to 
new investors. The following table illustrates this dilution:

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

   The following discussion should be read in conjunction with the 
accompanying financial statements and notes thereto appearing elsewhere in 
this Prospectus. 

Overview 

   Thinking Tools commenced operations in December 1993 to develop and market 
business simulation software. Since its inception, the Company has been 
engaged in research and development activities and organizational efforts, 
including the development of its initial products, recruiting personnel, 
establishing marketing and manufacturing capabilities and raising capital. 

   Thinking Tools commenced commercial activities in January 1994, but to 
date has not generated substantial revenues from the sale of its products. 
Revenues generated to date have been primarily derived from software 
development projects completed under contracts with customers. Historically, 
a significant portion of such revenues have been derived from a limited 
number of relatively large development projects contracted for by a small 
number of customers. To the extent that the Company's business continues to 
be derived from a limited number of large customer orders, any inability by 
the Company as it completes such orders to obtain new orders could have a 
material adverse effect on the Company's business, financial condition and 
results of operations. The Company is currently working on a limited number 
of customer orders. There can be no assurance that the Company will obtain 
additional sources of revenue prior to completing such projects. The 
Company's current strategy is to change its focus from custom projects to 
self-funded development of simulations for broader markets by leveraging its 
existing products and technology platform to become a product-oriented, 
sales-driven company. See "Business--Growth Strategy" and "Risk 
Factors--Fluctuations in Operating Results; Substantial Revenues Derived from 
Limited Customers." 

   As of June 30, 1996, the Company had experienced cumulative losses of 
$1,997,000 and had not experienced any quarter of profitable operations. The 
Company expects to incur additional operating losses for the foreseeable 
future. The Company's operations to date have been funded primarily through 
private sales of debt and equity securities. 

   Thinking Tools expects to incur substantial operating expenses in the 
future to support its development costs, expand its sales and marketing 
capabilities and organization, expand its work force and for other general 
and administrative expenses. The Company's results of operations may vary 
significantly from quarter to quarter during this period of development. 

Results of Operations 

   Comparison of six months ended June 30, 1996 and June 30, 1995 

   Revenues. Revenues for the six months ended June 30, 1996 decreased by 
$42,000, or 6%, to $634,000, from $676,000, for the six months ended June 30, 
1995. During each of such periods the Company's revenues were derived 
primarily from a relatively small number of development contracts. See 
"Business--Customers." 

   Gross Margin. Gross margin for the six months ended June 30, 1996 were 44% 
of revenues as compared with 45% of revenues for the six months ended June 
30, 1995. 

   Selling, General and Administrative Expenses. Selling, general and 
administrative expenses increased by $175,000, or 49%, for the six months 
ended June 30, 1996 to $532,000, or 84% of revenues, from $357,000, or 53% of 
revenues, for the six months ended June 30, 1995. Selling expenses included 
costs of 

                                      19 

<PAGE>

preparing project proposals and software demonstrations. General and 
administrative expenses consisted primarily of labor costs and consulting 
expenses. The increase in selling, general and administrative expenses was 
primarily due to increased consulting expenses, travel expenses, new 
insurance policy premiums, recruiting fees and increased involvement by the 
Company's technical development team in the preparation of Company's 
proposals and presentations. 

   Upon completion of this Offering, the Company intends to hire additional 
personnel to expand the Company's marketing and sales capabilities. See 
"Business--Marketing and Sales Strategy." Additionally, the Company expects 
general and administrative expenses to increase in future periods as the 
Company incurs additional costs related to being a public company and expands 
its staff and facilities. 

   Research and Development. Research and development expenses for the six 
months ended June 30, 1996 decreased by $114,000, or 66%, to $60,000, or 9% 
of revenues, from $174,000, or 26% of revenues, for the six months ended June 
30, 1995. This decrease was primarily due to the shifting of development 
efforts from initial internal software development to customer software 
development contracts. 

   As the Company's business strategy shifts from custom development projects 
to product sales, the Company expects that research and development expenses 
will increase. See "Business--Growth Strategy" and "Risk Factors--Risks 
Associated with Growth Strategy." 

   Interest Expense. Interest expense for the six months ended June 30, 1996 
increased by $17,000, or 28%, to $77,000, or 12% of revenues from $60,000, or 
9% of revenues, for the six months ended June 30, 1995. This increase was 
primarily due to the conversion of $180,000 of accrued interest due to 
Technologies into debt, borrowings of $52,100 under a bank line of credit and 
an additional loan from Technologies in the amount of $352,000, which loans 
bear interest at rates of 10%, prime plus 5% and prime plus 7%, respectively. 

   Other Income. Other income for the six months ended June 30, 1996 
increased by $33,000, or 330% to $43,000, or 7% of revenues from $10,000, or 
1% of revenues, for the six months ended June 30, 1995. This increase was 
primarily due to an increase in fees received for assisting customers with 
product presentations and demonstrations in connection with the resale by 
such customers of the Company's products. 

   Net Loss. As a result of the foregoing, net loss for the six months ended 
June 30, 1996 increased by $66,000, or 24%, to $346,000 from $280,000 for the 
six months ended June 30, 1995. 

   Comparison of years ended December 31, 1995 and 1994 

   Revenues. Revenues for the year ended December 31, 1995 ("Fiscal 1995"), 
increased by $483,000, or 57%, to $1,329,000 from $846,000 for the year ended 
December 31, 1994 ("Fiscal 1994"). This increase was primarily due to an 
increase during Fiscal 1995 in the number of contract projects. See 
"Business--Customers." 

   Gross Margin. Gross margin for Fiscal 1995 increased to 47% of revenues 
from 13% of revenues for Fiscal 1994. This increase was partially due to 
improved control of project costs in Fiscal 1995 as well as more skillful 
pricing and contract negotiating. Overruns on two projects in 1994 (both 
incurring losses) reflected the unanticipated high level of costs involved in 
developing the Company's complex agent-based simulation software. 

   Selling, General and Administrative Expenses. Selling, general and 
administrative expenses for Fiscal 1995 increased by $356,000, or 90%, to 
$751,000, or 57% of revenues, from $395,000, or 47% of revenues, for Fiscal 
1994. This increase was primarily attributable to increased labor costs and 
consulting expenses in connection with the Company's efforts to establish a 
management team and increases in travel expenses and insurance policy 
premiums. 

   Research and Development. Research and development expenses for Fiscal 
1995 decreased by $61,000, or 16%, to $328,000, or 25% of revenues, from 
$389,000, or 46% of revenues, for Fiscal 1994. This decrease reflected the 
increased maturity of the Company's agent-based simulation development tools 
and techniques. 

                                      20 

<PAGE>

   Interest Expense. Interest expense for Fiscal 1995 increased by $84,000, 
or 150%, to $140,000, or 11% of revenues, from $56,000, or 7% of revenues, 
for Fiscal 1994. This increase was primarily due to the borrowing from 
Technologies of $1,200,000 in September 1994 and, during the second half of 
Fiscal 1995 borrowings under a bank line of credit with an outstanding 
balance as of December 31, 1995 of $79,000 and from Technologies with an 
outstanding balance as of December 31, 1995 of $122,000, which loans bear 
interest at rates of 10%, prime plus 5% and prime plus 7%, respectively. 

   Other Income. Other income for Fiscal 1995 increased to $10,000 from none 
in Fiscal 1994, which increase resulted from an insurance payment on property 
losses. 

   Net Loss. As a result of the foregoing, net loss for Fiscal 1995 decreased 
by $142,000 or 19%, to $589,000 from $731,000 for Fiscal 1994. 

Liquidity and Capital Resources 

   Since its inception and through December 31, 1995 and June 30, 1996, the 
Company has incurred cumulative losses aggregating approximately $1,650,000 
and $1,997,000, respectively, and has not experienced any quarter of 
profitable operations. The Company expects to continue to incur operating 
losses for the foreseeable future, principally as a result of expenses 
associated with the Company's product development efforts and anticipated 
sales, marketing and general and administrative expenses. During the past two 
fiscal years, the Company has satisfied its cash requirements principally 
from advances from stockholders and private sales of equity securities and, 
to a limited extent, from cash flows from operations. The primary uses of 
cash have been to fund research and development and for sales, general and 
administrative expenses. 



   At June 30, 1996, the Company had cash of approximately $7,000 and a 
working capital deficit of approximately $617,000. As of the date hereof, the 
Company's total debt obligations (exclusive of trade credit) consist 
primarily of $1,825,000 principal amount payable to the holders of the Bridge 
Notes. See "Certain Relationships and Related Transactions" and "Description 
of Securities-Bridge Notes." The Bridge Notes will be repaid using net 
proceeds of this Offering. See "Use of Proceeds." 

   Net cash used in operating activities for Fiscal 1994, Fiscal 1995 and the 
six months ended June 30, 1996 totalled approximately $490,000, $297,000 and 
$549,000, respectively. Net cash provided by financing activities for Fiscal 
1994, Fiscal 1995 and the six months ended June 30, 1996 totalled 
approximately $790,000, $195,000 and $405,000, respectively, reflecting the 
proceeds from borrowings from stockholders, offset by principal repayments of 
$500,000 and $27,000 in Fiscal 1994 and the six months ended June 30, 1996, 
respectively. 

   Based on the Company's operating plan, the Company believes that the net 
proceeds of this Offering, together with revenues from continuing operations, 
will be sufficient to satisfy its capital requirements and finance its 
operations for at least the next 18 months. Such belief is based upon certain 
assumptions, and there can be no assurance that such assumptions are correct. 
The Company may be required to raise substantial additional capital in the 
future in order to carry out its business plan. In addition, contingencies 
may arise which may require the Company to obtain additional capital. 
Accordingly, there can be no assurance that such resources will be sufficient 
to satisfy the Company's capital requirements for such period. The Company 
anticipates that any additional financing required to meet its current plans 
for expansion may take the form of the issuance of common or preferred stock 
or debt securities, or may involve bank financing. There can be no assurance 
that the Company will be able to obtain such additional capital on a timely 
basis, on favorable terms, or at all. In any of such events, the Company may 
be unable to implement its business plan. 

Inflation 

   The impact of general inflation on the Company's business has been 
insignificant to date and the Company believes that it will continue to be 
insignificant for the foreseeable future.

   Thinking Tools develops powerful and flexible PC-based business simulation 
software programs that enable users to simulate real life business 
situations, explore complex operational problems and improve functional and 
problem solving skills. The Company's agent-based, adaptive simulation 
software has a broad range of potential business applications, including 
strategic planning, sales and marketing, training, competitive positioning, 
product marketing, operational planning, logistics and supply and demand 
forecasting. The Company believes that its products are unique because they 
combine user-friendly interactive interfaces used in sophisticated computer 
games with its proprietary agent-based programming to produce interactive 
adaptive business simulations. Agent-based, adaptive simulations can be used 
to model competitive situations, simulate consumer behavior, demonstrate the 
impact of management actions, seek system vulnerabilities and explore complex 
operational systems. The Company's user-friendly interfaces enable persons 
with no technical training to comfortably interact with complex systems. 

   The Company's agent-based programming enables autonomous agents in the 
simulation to respond to user behaviors in unpredictable and realistic ways. 
In contrast to other modelling and simulation tools in use and known to the 
Company, which are generally built around a limited number of agents acting 
according to pre-programmed, deterministic algorithms, the multiplicity of 
autonomous agents and the results of their interactions with each other and 
the user give the Company's simulations a complexity that mirrors human 
behavior found in the real world. 

   The Company's capabilities in developing highly sophisticated simulations 
are built upon experience gained from developing computer games, its skill in 
programming autonomous and adaptive agents and its large and growing library 
of reusable simulation objects. The Company's creative control is based on 
its proprietary development environment, WHITEBOARD, which supports interface 
building, object creation, simulation management, object management and 
application frameworks. WHITEBOARD simplifies and supports the construction 
of agent-based simulations and is the core of the development of each of the 
Company's simulations. 

   The Company was formed to purchase, on December 31, 1993, certain assets 
of the Division of Maxis, a leading computer game company and creator of the 
simulation game SimCity(tm). Through the purchase agreement with Maxis, the 
Company acquired the Division's equipment, staff, work-in-progress, 
customers, prospects, software tools, libraries and processes. 

Industry Overview 

   Simulations were among the earliest computer applications. Since the first 
days of digital computers, simulations using equations have been applied to 
scientific and engineering problems. Business simulations first began to 
appear shortly thereafter. Companies have attempted to simulate complex 
adaptive systems with models that were either fixed (deterministic) or 
stochastic (probability- based). Alternatively, they have developed their own 
custom systems based on executive information system (EIS) software packages. 
In all cases, the models lacked the adapting and evolving characteristics of 
real world systems; particularly because the most interesting business 
systems are made up of elements (e.g., customers, competitors and markets) 
that adapt their behaviors to each other. The elements in these systems 
modify their external behavior and internal structure in order to make more 
efficient use of their environments. Models based on formulae alone cannot 
effectively recreate these complex, adaptive systems. 

                                      22 

<PAGE>
 
In order to imitate these systems, models must themselves be adaptive. 
Some definitions will help to explain how this is accomplished: 
Object. A capsule of data and logic that are thematically related. 

(bullet) Agent. An object that can act on its environment.

(bullet) Autonomous Agent. An agent that selects its behavior with the goal of
         achieving a better fit to the requirements of its environment.

(bullet) Adaptive Agent. An agent that creates new behaviors in a non-random way
         with the goal of achieving a progressively better fit to the
         requirements of its environment.

   A fusion of techniques from biology (natural selection, evolution and 
genetics) and from computer science (cellular automata) led to early results 
in development of adaptive agents during the 1970's and up to the late 
1980's. The use of adaptive agents customizes the learning experience for 
each user by allowing the simulation to discern user vulnerabilities and 
confront the user with simulated events that focus on those weaknesses. This 
hostile environment introduces the challenges that a particular user needs 
most to understand. Simulation-based training using adaptive agents 
emphasizes diagnosis, planning and problem solving skills rather than rote 
learning or routine/automatic responses. 

   The Company believes that adaptive simulation methods are most effective 
in the following applications: 

(bullet) Training. Adaptive simulation-based training focusing on real time 
         diagnosis, planning and problem solving. 

(bullet) Rehearsal. Individual and group rehearsal of responses to simulated 
         contingencies used to evaluate the users' ability to handle various 
         emergencies. 

(bullet) Shared Awareness. Simulation of proposed uses of critical knowledge. 
         Where does each department or employee fit; what does the business 
         look like; what changes are necessary and why; what is the plan? 

(bullet) Hypothesis Testing and Rule Finding. Simulations that apply rules 
         that govern the behavior of a critical system. What are the rules 
         that govern the behavior of individual elements (e.g., customers 
         within a market segment); and how do elements interact with each 
         other? 

(bullet) Leverage Finding. Simulations that apply the present understanding 
         of the system's condition and the rules for its elements. Where are 
         the critical leverage points for creating big swings with economic 
         application of force? How will the system amplify applications of 
         force? 

   The adaptive business simulation software industry is in its infancy. When 
computing power was prohibitively expensive, only the largest companies could 
hope to gain the benefit of sophisticated business simulation. But, as 
computing power has dropped in price, even small companies have come to 
possess hardware capable of supporting adaptive simulations, provided that 
the software is available. The market for adaptive simulation software is 
expected by the Company to continue to grow dramatically as the fixed cost of 
supporting hardware continues to drop. 

   The Company believes that the use of simulation models in the business 
world will continue to increase as a result of the following: 

                                      23 

<PAGE>
 
(bullet) Increasing use of computers to assist decision-makers with complex 
         strategic issues, including operational support software for problem 
         management and resolution. 

(bullet) Increasing corporate demand for more sophisticated forecasting tools 
         than are provided by executive information systems and on-line 
         analytical processing software. 

(bullet) Increasing recognition of models and simulations as cost-effective 
         alternatives to specialized personnel in the areas of marketing and 
         sales. 

(bullet) Increasing use of multi-media software to support collaboration 
         among geographically separated workgroups. 

(bullet) Increasing PC performance allowing the use of advanced graphics and 
         multi-media to represent business situations. 

(bullet) Increasing importance of competitive product positioning and 
         shortening the development time for products. 

The Thinking Tools Solution 

   The Company's approach to simulation is known as agent-based, adaptive 
simulation (as distinct from equation-based simulation). Agent-based methods 
involve software environments filled with many agents. As the agents interact 
they individually select behavior rules that guide their actions. These 
actions in turn influence the rule selections made by other agents. The 
behavior that results from the application of all of these individual 
behavior rules is called emergent behavior. 

   One example of emergent behavior is temperature. Although individual 
molecules in the atmosphere of a room, have a location and velocity, they do 
not have temperature. Temperature results from the interactions of all of the 
molecules in the room's atmosphere. Temperature is a measure of emergent 
behavior. Emergent behavior is typically far more complex than the behavior 
of an individual agent particularly where the agents are adaptive. Emergent 
behavior simulation developed by the Company allows the behavior of a 
business process, organization or market to be simulated. 

   The Company combines its experience in developing agent-based simulations 
with experience derived from the development of computer games and their 
human interface style. Most software presents the user with an information 
surface: users put information onto the surface and the software processes 
it, or the software puts information onto the surface and users make use of 
it. The human interface used in many computer games is an artificial 
environment created by software and reflected in a multi-media format. Users 
perceive and sometimes shape or manage the systems present in those places. 
This style is much more closely related to film or theater than to interfaces 
found in other types of software. In most of its projects to date, the 
Company has combined the use of agent-based methods and computer game 
interface techniques. The Company produces software products that are 
accessible and adaptive. These tools make it easy for users to become 
involved and assume a role in the system that they are exploring. 

   The Company's business process simulations treat complex management tasks 
which require almost continuous use of judgment, insight and problem solving 
skills, focusing on assisting users to develop these skills. The simulations 
also provide operational support that helps users as they plan and solve 
problems. These simulations promote the user's thinking about the complex 
systems upon which their operations depend. The Company believes that the 
principle competitive advantages of its products over other business process 
simulations are the adaptive nature of its simulations and its proprietary 
development interface, WHITEBOARD. WHITEBOARD supports interface building, 
object creation, simulation management, object management and application 
frameworks.

Growth Strategy 

   The Company devoted its initial efforts to demonstrating the feasibility 
of the use of adaptive simulation for business applications by developing 
customized software programs for large clients pursuant to strategic 
distribution arrangements. The Company also assembled a highly-skilled 
technical team, established a growing library of reusable objects and 
enhanced its WHITEBOARD technology. 

   The Company's success in completing major projects for industry leaders 
who have validated the concept underlying the Company's technology, has 
positioned it to expand the scope of its operations to include the 
development of internally-funded software products and the direct marketing 
of the Company's products, in addition to continuing to selectively accepting 
projects funded by third parties. 

   The Company's goal is to develop a variety of simulations in divergent 
business areas. As a part of this strategy, the Company intends to undertake 
self-funded development of new simulations with broader market appeal and to 
adapt certain previously developed simulations, rights to which were retained 
by the Company, for sale as turnkey packages to new vertical markets. The 
Company will also, upon request, customize these packages on a project basis. 

   The Company plans to continue to expand its custom business selectively, 
while moving to invest in specific horizontal and vertical products and 
distribution channels aimed at the high end corporate and professional 
service markets. The Company intends to focus its custom business on projects 
that either allow for further development of an important technology on a 
paid basis, or facilitate the development of relationships with distribution 
partners which could provide benefits to the Company beyond the custom 
project. Custom projects will not be limited exclusively to the corporate 
sector, but may include the military and intelligence communities, because of 
their interest in leading edge technology. An important feature of the 
Company's "custom" strategy is to reduce the required amount of custom 
development for each product, and therefore its cost. The Company will seek 
to accomplish this goal by increasing its use of semi-custom designs (design 
families) and through improved development of object library creation 
techniques. 

   In the future, the Company may occasionally agree to work with a customer 
to produce a retail, shrink-wrapped product. In such cases, it is expected 
the customer would pay the entire cost of development and the Company would 
receive an ongoing royalty on all retail sales. The Company believes that 
only in such cases would its products be brought to market through a retail 
channel. 

   The Company intends to build management depth and breadth and expand the 
Company's marketing and sales capabilities. The Company intends to hire a 
chief executive officer and chief financial officer. The Company also intends 
to hire a senior marketing and sales executive to further develop the product 
strategy and implement and expand the Company's distribution strategy. The 
Company plans to establish a small direct sales force to focus on key 
products and markets and to solicit custom business. The Company intends to 
utilize a substantial portion of the net proceeds of this Offering for 
implementing this growth strategy. See "Risk Factors--Limited Marketing 
Experience; Need for Additional Personnel", "-- Risks Associated with Growth 
Strategy" and "Use of Proceeds." 

Products 

   The Company's products are fully-graphical, interactive and provide 
constant graphical feedback with a wide variety of responses to the user's 
actions. To date, the Company's technology has been used to develop a variety 
of such products. 

   SimRefinery is a demonstration program which was released by the Division 
in late 1992 and purchased by the Company along with certain assets of the 
Division. SimRefinery serves as the Company's 

                                      25 

<PAGE>
 
model demonstration program. The program shows how supply and demand 
conditions interact, the impact on the financial performance of the refinery 
of changes in supply and demand conditions and of changes in marketplace 
objectives. The user learns about refineries through taking an active role in 
the simulation as the plant manager of the refinery. 

   SimHealth is a simulation of the impact of various proposed reforms on the 
United States health care system and has some 5,000 objects. It simulates 
both the supply and demand sides of health care, shows the impact of choices 
and values on the financial health of the system and of its usage and demand. 
The program was developed for the Markle Foundation in 1994 under a contract 
negotiated by the Division, and assumed and completed by the Company. 

   TeleSim is a simulation of the local exchange telephone market for a 
particular region and competitors in that region. The package simulates the 
world of a telephone company, including the particular user's sales and 
service regions and its market opportunities and vulnerabilities. The user 
can actively explore the impact on the financial performance of the 
corporation and the impact on its competitive environment of changes in the 
conditions of supply and demand or emphasis of different corporate 
objectives. Competing companies are driven by adaptive agents that base their 
strategies in part on the actions taken by the user. TeleSim has some 12,000 
objects. Since its initial development under a contract with Coopers in 1994, 
subsequent versions of TeleSim have been produced and sold through Coopers to 
Sprint Corp. and AT&T Corp. 

   Project Challenge, is a simulation for project management of information 
systems projects. Project Challenge users create a model of their projects, 
then operate the projects under benign, realistic or hostile environments. A 
variety of novel displays keep the user informed about project conditions, 
including scheduling, budget and human resources. This simulation program can 
assist in both training and operational roles. Project Challenge is highly 
sophisticated, incorporating over 15,000 objects. The development of the 
simulation is being funded by SystemHouse; however, the Company retained the 
rights to create variations of this specific simulation for other kinds of 
project management, such as construction projects, and is currently working 
on other business simulation projects. The Company anticipates that Project 
Challenge will also serve as a foundation for training or performance support 
applications in other occupational fields. 

Product Development 

   The Company believes that its programming technology, resources and 
experience will allow it to move beyond the current generation of simulation 
products. Several advanced capabilities developed and cultivated by the 
Company since its inception play a critical role in its product development 
work. 
The Company has developed a process for investigating, describing and 
modeling complex adaptive systems. Conceptual and detailed design steps in 
this process make it possible to translate an understanding of the complex 
adaptive system into specifications required by programmers to build the 
final product. The Company has developed and refined its ability to program 
adaptive agents to produce new behaviors at run time, while remaining within 
a range of realistic behavior. 

   The Company continues to introduce and apply newer, more powerful 
techniques for programming its agents, often incorporating methods based on 
biological processes. 

   The Company has succeeded in creating a class of "bad agents," known as 
Malion, to explore vulnerabilities in systems, networks or practices so that 
the user can then repair them. 

   The following markets are ones in which the Company is either already 
pursuing, or plans to pursue, product applications. See "Risk 
Factors--Dependence on Emerging Market for Business Simulation Software" and 
"--Uncertainties Related to Development of Additional Products." 

                                      26

Business Management, Sales and Training. In these simulations, the Company 
intends to focus on markets that lend themselves specifically to the 
strengths of simulation, namely markets requiring simulations mirroring 
circumstances involving multiple central variables amongst which tradeoffs 
continually need to be made, with outcomes that are not always intuitively 
obvious. An example of a business process simulation is Project Challenge, 
which trains corporate employees in the art of project management. The 
Company has begun development of its second product in this category which 
will focus on the sales process and the interpersonal skills critical to the 
sales process. Products in the business process category generally will be 
designed to support easy field-modification by the training department or 
student, but will not require custom programming by the Company. 

   Contingency and Security. These proposed simulations will provide 
emergency response service providers with a means of training, rehearsing and 
planning their disaster recovery procedures. The Company believes that this 
field is particularly appropriate for simulation since all parts of an 
organization must be involved, the actual event being prepared for happens 
rarely, if at all, and the consequences of the event can be disastrous if not 
handled properly. The first proposed product will treat information 
technology recovery for corporations, but related products may be developed 
for other forms of emergency response. 

   Internet and Intranet Simulations as Marketing Tools. Simulations of a 
host's business would reside on its home page or intranet and combine the key 
properties of adaptive and interactive simulators with the accessibility of 
wide area networks. Because these proposed simulations will emulate games, 
the Company believes that internet users will view them as compelling and 
engaging ways to spend time. While protecting the individual consumers' 
identity, the site would track and provide to the host valuable marketing 
information relating to the way consumers learn, think and decide about the 
hosts' products, and depending on design perhaps, competitive products as 
well. In this way the host could collect valuable marketing information. 

   Adaptive Supply and Distribution. The Company has completed a proof of 
concept simulation in the area of self-ordering distribution that the Company 
believes could change the way companies think about and plan their supply, 
distribution, replenishment and logistics capabilities. The Company believes 
that a simulation of this type would be of substantial interest in corporate, 
military and other government circles. 

   Thought and Decision Processes. The Company is working on a simulation 
that ascribes motives, goals, thoughts and strategies to other people or 
groups in order to make sense of their past behavior and to anticipate their 
future behavior. The simulation provides users with a means of building and 
updating models of the thought and decision processes of other individuals or 
groups including, for example, the competition or other departments within an 
organization. The product is intended to create a picture of this dynamic and 
often very complex process that helps the user to explore what she knows or 
assumes about the process. This simulation will be used to clarify 
communication with others and to further understand the thought process under 
examination. The first application in development is in the area of complex 
strategic decision-making. Future commercial applications will be designed to 
help corporate customers as they collect, organize and apply this complex and 
subtle knowledge about their business decisions, or those of their 
competitors and customers. 

Customers 


   Historically, the Company has sold its products to a number of large 
companies, as well as governmental agencies, foundations, text book and 
traditional publishers and consulting firms. The following list identifies 
certain of the Company's customers: 


<TABLE>

   Some of the Company's customers have contracted for the Company's 
development of specific simulations in order to resell such simulations as a 
value added component of their consulting or other services. The following 
list identifies certain end-users who have purchased the Company's products 
directly from customers of the Company:

         U.S. Army                U.S. Air Force 
</TABLE>

   Sales to three customers for the six months ended June 30, 1996 accounted 
for 33%, 32% and 18%, respectively, of the Company's sales for the six months 
ended June 30, 1996. Sales to three customers in Fiscal 1995 accounted for 
27%, 14% and 13%, respectively, of the Company's sales in Fiscal 1995. Sales 
to two customers in Fiscal 1994 accounted for 59% and 17%, respectively, of 
the Company's sales in Fiscal 1994. 

Marketing and Sales Strategy 

   To date, the Company has not devoted significant financial resources to 
marketing, and customers have come through word-of-mouth or following 
referrals from Maxis and others. The Company has also generated inquiries by 
presentations at industry and academic forums with high level corporate 
audiences. John Hiles, the founder of Thinking Tools, is a highly sought 
after speaker at such events. 

   The Company intends to distribute its product through existing channels of 
its strategic partners as well as by initiating direct sales to customers 
through its proposed sales force, and through distributors and value added 
resellers ("VARs"). The Company has marketing agreements with Coopers for 
TeleSim and with SystemHouse for Project Challenge. The Company is also in 
discussion with additional prospective VARs. As the Company moves into new 
specific product areas, it intends to seek strategic alliances in such areas. 
The Company plans to continue making presentations and appearances at 
academic forums and corporate-sponsored events. 

   Proceeds from this Offering will be used to implement the Company's 
marketing and sales efforts. The Company expects to hire a direct sales force 
following this Offering. A senior marketing and sales executive is expected 
to be hired to further develop the product strategy and implement and expand 
the Company's distribution strategy. See "Risk Factors--Limited Marketing 
Experience; Need for Additional Personnel" and "Use of Proceeds." 

Intellectual Property 

   The Company does not have any patents and has not filed patent 
applications on its products because patents are often insufficient to 
protect software. The Company regards the software that it owns or licenses 
as proprietary and relies primarily on a combination of trade secret laws, 
nondisclosure agreements and other protection methods to protect its rights 
to its products and proprietary rights. 

   It is the Company's policy that all employees and third-party developers 
sign nondisclosure agreements. This may not afford the Company sufficient 
protection for its know-how and its proprietary products, and other parties 
may develop similar know-how and products, duplicate the Company's know- how 
and products or develop patents that would materially and adversely affect 
the Company's business. See "Risk Factors--Uncertainties Regarding 
Intellectual Property." 

   The Company believes that its products and services do not infringe the 
rights of third parties. However, there can be no assurance that third 
parties may not assert infringement claims against the Company, with such 
claims resulting in the Company being required to enter into royalty 
arrangements, pay other damages or defend against litigation, any of which 
could materially and adversely affect the Company's business.

The Core Technology Asset-WHITEBOARD 

   WHITEBOARD is a collection of technologies that allows the software 
developer to build a business simulation for any type of company or industry. 
WHITEBOARD incorporates in the simulations all major variables for situations 
defined by the programmer. The Company's simulation development process 
allows the programmer to change variables and to see the effect of any other 
combination of variables. WHITEBOARD is comprised of four main components: 

(bullet) An object-oriented database engine to manage and access thousands of
         objects while a simulation is running.

(bullet) A library of predefined business simulation objects and tools to enable
         the developer to edit these objects and to build customized objects.

(bullet) An object integration component to allow users to import and use
         objects from other technical environments, including other Company
         simulations.

(bullet) The technical capability to add multi-media effects and approaches.

   WHITEBOARD is a powerful tool for building simulations of complex adaptive 
systems critical for simulating business environments. WHITEBOARD was 
developed to provide programmers with a tool for easily building realistic 
business simulations with a capacity for adaptive behavior, realistic 
duplication of crisis or chaos situations and animation and graphical 
displays. While incorporating advanced object- oriented concepts, it also 
focuses on the graphics area and is designed for visual analysis. WHITEBOARD 
allows developers to add full multi-media effects including sound, graphics 
and digital video. This permits the designer to approach simulations in the 
most realistic way possible. WHITEBOARD runs on an IBM PC on Windows. It is 
written in the widely used language C and it runs with Novell software in a 
workgroup environment. It is unique in its ability to run in the PC 
environment. 

   The object-oriented database allows developers to build complex 
applications by importing existing objects from other of the Company's 
applications--both finished products and work-in- progress. The developer can 
also edit existing simulation objects or add new types of simulation objects 
to simulate new types of situations. In effect, the engine is a specialized 
tool for rapidly building business simulations. For example, a family of 
performance support or training applications for related occupations could be 
developed substantially faster than Project Challenge--the foundation upon 
which they could be based. 

   The Company plans to enhance WHITEBOARD to include tools that will allow 
the developer to build customized simulation objects based on library objects 
or other objects. The library of objects built into WHITEBOARD can be further 
extended so that generic situations and processes can be highly customized to 
the precise application required by the developer. 

   The WHITEBOARD technology has been validated through use in the 
development of the Company's products. Developers have been able to carry out 
design, simulation and testing that would have otherwise been inordinately 
time consuming and expensive at a fraction of the cost and the time spent. 
Use of WHITEBOARD has reduced the time required for prototyping the 
simulation and testing the marketing and launch of a product to a few months. 
The ability of WHITEBOARD to contribute to reductions in cycle time and to 
model strategic choices provides a significant competitive factor to the 
Company. 

Competition 

   The market for business simulation software is highly competitive, subject 
to rapid technological change and emerging industry standards. The Company 
believes that the principal competitive factors in its markets are product 
performance, product maintenance, support and price. The software industry in 
general is highly competitive and most established companies in the business 
software field are substantially larger and have greater financial resources 
than the Company. See "Risk Factors--Technological Change; Risk of 
Obsolescence; Industry Standards" and "--Competition" 

                                      29

   Presently, internal development of business simulations by companies 
seeking simulation capability represents the main source of competition to 
the Company's products and services. However, because it generally is not 
economical for a business to develop and continually upgrade such a product 
for its own needs alone, the Company believes that internal development 
produces a less cost effective solution to the developer's needs. 

   Internal developers are currently limited to using equation-based 
simulation tools for their simulation program development. Equation-based 
models will not duplicate the adaptive or chaotic behavior of systems 
available from the Company. No generally available sources of tools will help 
corporate technical staff to design models of complex adaptive systems 
competitive with those of the Company. Even with programming tools for 
agent-based simulations, design know-how like that refined and practiced at 
the Company would still be required to create rich and effective tools and 
are unlikely to be available in an in- house setting. 

   Authoring tools such as MacroMedia's Director and Asymmetrix' Toolbook can 
be used to develop parts of the user interface for simulations. Authoring 
tools are developing a rich suite of multimedia effects and are optimal for 
building interesting graphic user interfaces and interactive applications. 
However, these tools cannot match the extensive customized and specialized 
agent-based, adaptive simulation objects possessed by the Company. 

   The Company believes that the following companies constitute the principal 
participants in the business simulation software market at this time: 

   Aspen Technologies, Inc. ("Aspen") supplies computer-aided chemical 
engineering software products to the process manufacturing industries. 
Aspen's software allows chemical engineers to create mathematical models of 
manufacturing processes and to predict the performance of such procedures 
under varying equipment configurations and conditions. 

   GSE Systems, Inc. ("GSE") designs, develops and supplies high fidelity, 
real time simulation software, systems and services for the energy and 
manufacturing industries. GSE develops simulation products for nuclear power 
plants, fossil fuel plants, petroleum refineries, chemical processing plants 
and other industrial manufacturing plants. 

   Integrated Systems, Inc. provides software development tools in several 
industries. Its products help manufacturers develop and simulate dynamic

1996 Stock Option Plan 

   The Thinking Tools, Inc. 1996 Stock Option Plan (the "Plan") was adopted by
the board of directors and approved by the Company's stockholders in August
1996.

   The purpose of the Plan is to attract and retain key personnel. The Plan
provides for the grant of options to acquire a maximum of 376,000 shares of
Common Stock of which options to purchase 145,036 shares have been granted under
the Plan, including (i) options to purchase 41,036 shares of Common Stock
granted to certain members of the Company's board of directors under the Plan,
at an exercise price of $1.00 per share, (ii) options to purchase 52,000 shares
of Common Stock granted to certain of the Company's employees at an exercise
price of $.79 per share and (iii) options to purchase 52,000 shares of Common
Stock granted to certain of the Company's employees at an exercise price of
$5.00 per share. The Plan permits the granting of incentive stock options
("ISOs") or non-qualified stock options ("NSOs") at the discretion of the
administrator of the Plan (the "Plan Administrator"). The board of directors
acts as the Plan Administrator. Subject to the terms of the Plan, the Plan
Administrator determines the terms and conditions of options granted under the
Plan. Options granted under the Plan are evidenced by written agreements which
contain such terms, conditions, limitations and restrictions as the Plan
Administrator deems advisable and which are not inconsistent with the Plan. ISOs
may be granted to individuals who, at the time of grant, are employees of the
Company or its affiliates. NSOs may be granted to directors, employees,
consultants and other agents of the Company or its affiliates. The Plan provides
that the Plan Administrator must establish an exercise price for ISOs that is
not less than the fair market value per share of the Common Stock at the date of
grant. Each ISO must expire within ten years of the date of grant. However, if
ISOs are granted to a person owning more than 10% of the voting stock of the
Company, the Plan provides that the exercise price may not be less than 110% of
the fair market value per share at the date of grant and that the term of such
ISOs may not exceed five years. The Plan Administrator has the authority to
establish vesting periods for options granted under the Plan, or to grant
options which are fully vested at the time.

   An optionee whose relationship with the Company or any related corporation
ceases for any reason (other than termination for cause, death or total
disability, as such terms are defined in the Plan) may exercise options in the
three-month period following such cessation (unless such options terminate or
expire sooner by their terms), or in such longer period determined by the Plan
Administrator in the case of

                                      35 

<PAGE>
 
NSOs. Unexercised options granted under the Plan terminate upon a merger 
(other than a stock merger), reorganization or liquidation of the Company; 
however, immediately prior to such a transaction, optionees may exercise such 
options without regard to whether the vesting requirements have been 
satisfied. 

Options granted under the Plan convert into options to purchase shares of 
another corporation involved in a stock merger with the Company, unless the 
Company and such other corporation, in their sole discretion, determine that 
such options terminate. Such converted options become fully vested without 
regard to whether the vesting requirements in the option agreement for such 
options have been satisfied, unless the board of directors determines 
otherwise. 

The option exercise price may be paid in full at the time the notice of 
exercise of the option is delivered to the Company and must be paid in cash, 
by bank certified or cashier's check or by personal check. Options are 
nontransferable with certain exceptions. The board of directors has certain 
rights to suspend, amend or terminate the Plan provided stockholder approval 
is obtained. 

Options Granted Outside the Plan 

   In addition to the ISOs and NSOs which may be granted under the Plan, as at
June 30, 1996 the Company has granted options to purchase an aggregate of (i)
58,964 shares of Common Stock outside of the Plan at an exercise price of $.79
per share, to certain of its directors in connection with the directors joining
the Company's board of directors and (ii) 15,000 shares of Common Stock outside
of the Plan at an exercise price of $1.00 per share, to a non-affiliate of the
Company.

                              CERTAIN TRANSACTIONS

   In connection with its purchase of certain assets from Maxis, and in order 
to fund its continuing operations, the Company entered into a stock purchase 
and loan agreement, dated September 28, 1994 between and among Technologies 
and the Company (the "Technologies Agreement"). Technologies was formed by 
Knoll Capital Management, L.P. in order to purchase Common Stock of the 
Company and to advance the funds provided for under the Technologies 
Agreement. The general partner of Technologies is Knoll Capital Management, 
L.P., an affiliate of Mr. Fred Knoll, the Company's Chairman of the Board. 
Mr. Mort Meyerson, a member of the advisory board of the Company, is a 
limited partner in Technologies. 

   Pursuant to the Technologies Agreement, Technologies purchased 61.11% of 
the Company's authorized and issued Common Stock, for the purchase price of 
$100,000 and loaned to the Company $1,200,000 (the "Loan"). The Loan was 
evidenced by a promissory note (the "Technologies Note") due and payable on 
September 27, 1999. The Technologies Note provides for the semi-annual 
payment of interest at ten percent (10%) per annum beginning when and if the 
Company realized $2,000,000 in gross income during any fiscal year. No 
interest has been paid on the Loan. In connection with the Technologies 
Agreement, Mr. Hiles executed an irrevocable proxy authorizing Knoll Capital 
Management, L.P. to vote his shares of Common Stock, which proxy is effective 
until the Company (i) is acquired through a merger or acquisition; or (ii) 
effects an initial public offering in the aggregate amount of $2,500,000. On 
and before July 29, 1996, Technologies made additional loans to the Company 
in an aggregate principal amount of $502,000, with interest at a rate of 10% 
per annum, which loans were due and payable on December 31, 1996 (the 
"Additional Loan"), but were repaid in connection with the Bridge Financing. 
In connection with the Additional Loan, Technologies received warrants to 
purchase 468,242 shares of Company Common Stock at an exercise price of $1.07 
per share. See "Description of Securities--Technologies Warrants." 

   Pursuant to the Technologies Agreement, as long as Technologies owns 20% 
of the Company's Common Stock, the Company may not take certain actions 
without the approval of the Company's board of directors. Technologies has 
entered into a Consent, Waiver and Amendment dated as of August 28, 1996 (the 
"Consent & Waiver") with the Company in connection with the Bridge Financing 
providing that these covenants shall terminate upon consummation of this 
Offering. 

   In connection with the Technologies Agreement, the Company and Mr. Hiles 
agreed to certain co-sale rights and registration rights. Pursuant to the 
Consent and Waiver, these rights will terminate upon consummation of this 
Offering. 

   In addition, in connection with the Bridge Financing, pursuant to the 
Consent and Waiver, the following transactions were consummated: 

   Thinking Tools, Inc., a California corporation ("TTI"), was merged with 
and into its wholly-owned subsidiary Thinking Tools, Inc., a Delaware 
corporation. Pursuant to the Merger, each share of common stock of TTI 
outstanding prior to the Merger was exchanged for .7462 shares of Common 
Stock. 

   Pursuant to a plan of recapitalization adopted by the Company's board of 
directors, Technologies converted $1,200,000 aggregate principal amount of 
outstanding indebtedness and $120,310 of accrued interest into an aggregate 
of 263,158 shares of Common Stock issued to Technologies. 

   Technologies purchased $625,000 aggregate principal amount of Bridge Notes 
in the Bridge Financing immediately following repayment by the Company of 
$502,000 aggregate principal amount of outstanding indebtedness and $123,000 
of accrued interest due to Technologies from the proceeds of the Bridge 
Financing.

                           DESCRIPTION OF SECURITIES

   The following summary description of the Company's capital stock is 
qualified in its entirety by reference to the Company's Certificate of 
Incorporation. The following summary description of the securities of the 
Company is qualified in its entirety by reference to the Certificate of 
Incorporation, the Technologies Warrants, the Bridge Notes and the Bridge 
Warrants, forms of which have been filed as exhibits to the Registration 
Statement on Form SB-2 of which this Prospectus forms a part. 

Common Stock 

   The Company is authorized to issue up to 20,000,000 shares of Common 
Stock, par value $.001 per share, of which 3,031,758 shares are outstanding 
as of the date hereof. Holders of Common Stock are entitled to one vote for 
each share held of record on each matter submitted to a vote of stockholders. 
There is no cumulative voting for election of directors. Subject to the prior 
rights of any series of preferred stock which may from time to time be 
outstanding, holders of Common Stock are entitled to receive ratably, 
dividends when, as, and if declared by the board of directors out of funds 
legally available therefor and, upon the liquidation, dissolution, or winding 
up of the Company, are entitled to share ratably in all assets remaining 
after payment of liabilities and payment of accrued dividends and liquidation 
preferences on any preferred stock. See "Risk Factors--Lack of Dividends" and 
"Dividend Policy." Holders of Common Stock have no preemptive rights and have 
no rights to convert their Common Stock into any other securities. The 
outstanding Common Stock is validly authorized and issued, fully paid, and 
nonassessable. 

Preferred Stock 

   The Company is authorized to issue up to 3,000,000 shares of preferred 
stock, par value $.001 per share, of which no shares are outstanding as of 
the date hereof. The preferred stock may be issued in one or more series, the 
terms of which may be determined at the time of issuance by the board of 
directors, without further action by stockholders, and may include voting 
rights (including the right to vote as a series on particular matters), 
preferences as to dividends and liquidation, conversion rights, redemption 
rights, and sinking fund provisions. The issuance of any such preferred stock 
could adversely affect the rights of the holders of Common Stock and, 
therefore, reduce the value of the Common Stock. The ability of the board of 
directors to issue preferred stock could discourage, delay, or prevent a 
takeover of the Company. See "Risk Factors--Anti-Takeover Effects of Certain 
Provisions of Certificate of Incorporation and Delaware Law." 

Technologies Warrants 

   The Company currently has outstanding Technologies Warrants to purchase up 
to 468,242 shares of Common Stock at an exercise price of $1.07 per share at 
any time until December 31, 2006. The Technologies Warrants contain 
anti-dilution provisions providing for adjustment of the exercise price and 
the number of shares of Common Stock underlying the Technologies Warrants 
upon the occurrence of certain events, including stock dividends, stock 
splits and recapitalizations. The Technologies Warrants also entitle the 
holders to certain "piggyback" registration rights with respect to the shares 
issuable upon exercise thereof at any time that the Company files a 
registration statement other than one relating solely to the sale of 
securities to participants in a Company employee benefit plan, one not 
including substantially the same information as would be required to be 
included in a registration statement covering the sale of such Common Stock, 
or one only registering Common Stock issuable upon conversion of convertible 
debt securities which are also being registered. 

                                      39 

<PAGE>

Bridge Units 

   The Bridge Units consist of the Bridge Notes and the Bridge Warrants. Each 
Bridge Unit consists of a Bridge Note issued by the Company in the principal 
amount of $100,000 and a Bridge Warrant to purchase up to 25,000 shares of 
Common Stock at an exercise price equal to the lesser of $4.20 per share or 
60% of the initial public offering price per share in this Offering. The 
Bridge Notes and the Bridge Warrants are separately transferable, subject to 
certain restrictions upon transferability. 

   Bridge Notes 

   The Bridge Notes bear interest at the rate of 10% per annum with interest 
to accrue from the date of issuance and payable in four quarterly 
installments on the first day of each December, March, June and September 
commencing on December 1, 1996 and at maturity. Principal of, and any accrued 
and unpaid interest on the Bridge Notes will be due and payable in full on 
the earlier of (i) the consummation of this Offering, (ii) one year from the 
date on which the Bridge Notes were issued, and (iii) the date of the closing 
of a sale (or the closing of the last of a series of sales) of securities by 
the Company or any subsidiary or affiliate thereof (other than the Bridge 
Notes and Bridge Warrants), the gross proceeds of which, in the aggregate, 
equal or exceed $1,825,000. The principal balance of the Bridge Notes, and 
accrued interest thereon, will be repaid with the net proceeds of this 
Offering. See "Use of Proceeds." 

   The Company has the right, at its option, to extend the maturity date of 
the Bridge Notes for up to one year. In the event that (A) the Company elects 
to extend such maturity date for six months, then the number of shares 
issuable upon the exercise of each Bridge Warrant shall automatically 
increase by an additional 5% for each month that the Bridge Notes continue to 
remain outstanding during such initial six-month period; and (B) the Company 
elects to extend the maturity date for an additional six months thereafter, 
then (i) the number of shares issuable upon the exercise of each Bridge 
Warrant shall automatically increase by an additional 10% for each month that 
the Bridge Notes continue to remain outstanding during such additional 
six-month period; and (ii) the Underwriter shall have the right to designate 
a number of directors constituting a majority of the board of directors until 
such time as the Bridge Notes and any accrued interest thereon are paid in 
full. 

   The Bridge Notes rank senior in right of payment to all Junior Debt of the 
Company, which is defined as all existing and future indebtedness other than 
(i) the indebtedness represented by the Bridge Notes; (ii) capital lease 
obligations; and (iii) certain other indebtedness permitted by the Bridge 
Notes. See "Certain Transactions." The Bridge Notes are secured by a lien on 
certain assets of the Company. 

   Bridge Warrants 

   The Bridge Warrants entitle the holders thereof to purchase, in the 
aggregate, up to 456,250 shares of Common Stock at an exercise price equal to 
the lesser of $4.20 per share or 60% of the aggregate initial public offering 
price per share of Common Stock in this Offering, subject to adjustment. The 
Bridge Warrants may be exercised at any time after issuance and expire on 
August 28, 2001. The shares underlying the Bridge Warrants are being 
registered in this Offering, and shall be subject to a two-year lock-up with 
the placement agent of the Private Placement. In addition, the holders of the 
Bridge Warrants are entitled to certain "piggyback" registration rights with 
respect to such shares except in connection with the registration of 
securities issuable under an employee benefit plan or in connection with 
certain other registration statements filed by the Company. 

   The number of shares issuable upon exercise of the Bridge Warrants and the 
exercise price thereof may be adjusted in the event of the occurrence of 
certain events, including stock dividends, stock splits, combinations or 
reclassifications involving or in respect of the Common Stock of the Company, 
or an extension by the Company of the maturity date of the Bridge Notes. If 
the Company extends the maturity 

                                      40 

<PAGE>

date of the Bridge Notes for a period of six months, the exercise price per 
share shall be decreased to the lesser of $3.50 per share or 50% of the 
initial public offering price per share. 

Stockholder Reports 

   The Company intends to furnish its stockholders with annual reports 
containing audited financial statements and such other periodic reports as 
the Company may deem appropriate or as may be required by law. 

Transfer Agent and Registrar 

   The Company has appointed Continental Stock Transfer & Trust Company as 
transfer agent for the Common Stock. 

Directors' Limitation of Liability and Indemnification 

   The Company's Certificate of Incorporation includes provisions which (a) 
eliminate the personal liability of directors for monetary damages resulting 
from breaches of their fiduciary duty (except for liability for breaches of 
the duty of loyalty, acts or omissions not in good faith or which involve 
intentional misconduct or a knowing violation of law, violations under 
Section 174 of the Delaware General Corporation Law ("DGCL"), or for any 
transaction from which the director derived an improper personal benefit) and 
(b) indemnify the directors and officers to the fullest extent permitted by 
the DGCL, including under circumstances under which indemnification is 
otherwise discretionary. The Company believes that these provisions are 
necessary to attract and retain qualified persons as directors and officers. 

   Section 145 of the Delaware General Corporation Law permits 
indemnification by a corporation of certain officers, directors, employees 
and agents. Consistent therewith, the Company's Certificate of incorporation 
requires that the Company indemnify all persons who it may indemnify pursuant 
thereto to the fullest extent permitted by Section 145. 

   The Company's Certificate of Incorporation and Bylaws provide that the 
Company will indemnify each of its directors and officers to the fullest 
extent permitted by law with respect to all liability and loss suffered and 
expenses incurred by such person in any action, suit or proceeding in which 
such person was or is made or threatened to be made a party or is otherwise 
involved by reason of the fact that such person is or was a director or 
officer of the Company. The Company is also obligated to pay the expenses of 
the directors and officers incurred in defending such proceedings, subject to 
reimbursement if it is subsequently determined that such person is not 
entitled to indemnification. 

   In addition, the Company's Certificate of Incorporation provides that the 
Company's directors shall not be liable to the Company or its stockholders 
for monetary damages for breaches of their fiduciary duties to the Company 
and its stockholders except to the extent such exemption from liability or 
limitation thereof is not permitted under the DGCL. This provision in the 
Certificate of Incorporation does not eliminate the duty of care, and in 
appropriate circumstances equitable remedies such as injunctive or other 
forms of non- monetary relief will remain available under the DGCL. In 
addition, each director will continue to be subject to liability for monetary 
damages for misappropriation of any corporate opportunity in violation of the 
director's duties, for acts or omissions involving intentional misconduct, 
for knowing violations of law, for actions leading to improper personal 
benefit to the director, and for distributions (including payment of 
dividends or stock repurchases or redemptions) that are unlawful under the 
DGCL. The provision does not affect a director's responsibilities under any 
other law, such as the federal securities laws. The Certificate of 
Incorporation further provides that if the DGCL is amended to authorize 
corporate action further eliminating or limiting the personal liability of 
directors then the liability of a director of the Company shall be eliminated 
or limited to the fullest extent permitted by the DGCL as amended or 
supplemented. 

                                      41 

<PAGE>
 
   The Company maintains a policy of insurance under which the directors and 
officers of the Company will be insured, subject to the limits of the policy, 
against certain losses arising from claims made against such directors and 
officers by reason of any acts or omissions covered under such policy in 
their respective capacities as directors or officers, including liabilities 
under the Securities Act. Insofar as indemnification for liabilities arising 
under the Securities Act may be permitted to directors, officers and 
controlling persons of the Company pursuant to the foregoing provisions, or 
otherwise, the Company has been advised that, in the opinion of the 
Commission, such indemnification is against public policy as expressed in the 
Securities Act and is, therefore, unenforceable. 

Delaware Anti-Takeover Law 

   The Company is subject to Section 203 of the DGCL ("Section 203") which, 
subject to certain exceptions and limitations, prohibits a Delaware 
corporation from engaging in any "business combination" with any "interested 
stockholder" for a period of three years following the date that such 
stockholder became an interested stockholder, unless: (i) prior to such date, 
the board of directors of the corporation approved either the business 
combination or the transaction which resulted in the stockholder becoming an 
interested stockholder; (ii) upon consummation of the transaction which 
resulted in the stockholder becoming an interested stockholder, the 
interested stockholder owned at least 85% of the voting stock of the 
corporation outstanding at the time the transaction commenced (for the 
purposes of determining the number of shares outstanding at the time the 
transaction commenced (for the purposes of determining the number of shares 
outstanding under the DGCL, those shares owned (x) by persons who are 
directors and also officers and (y) by employee stock plans in which employee 
participants do not have the right to determine confidentially whether shares 
held subject to the plan will be tendered in a tender or exchange offer are 
excluded from the calculation); or (iii) on or subsequent to such date, the 
business combination is approved by the board of directors and authorized at 
an annual or special meeting of stockholders, and not by written consent, by 
the affirmative vote of at least 66-2/3% of the outstanding voting stock 
which is not owned by the interested stockholder. 

   For purposes of Section 203, "a business combination" includes (i) any 
merger or consolidation involving the corporation and the interested 
stockholder; (ii) any sale, transfer, pledge or other disposition of 10% or 
more of the assets of the corporation involving the interested stockholder; 
(iii) subject to certain exceptions, any transaction which results in the 
issuance or transfer by the corporation of any stock of the corporation to 
the interested stockholder; (iv) any transaction involving the corporation 
which has the effect of increasing the proportionate share of the stock of 
any class or series of the corporation beneficially owned by the interested 
stockholder; or (v) the receipt by the interested stockholder of the benefit 
of any loans, advances, guarantees, pledges or other financial benefits 
provided by or through the corporation. Section 203 defines an "interested 
stockholder" as any entity or person beneficially owning 15% or more of the 
outstanding voting stock of the corporation and any entity or person 
affiliated with or controlling or controlled by such entity or person. 

                       SHARES ELIGIBLE FOR FUTURE SALE 

   Upon completion of this Offering, the Company will have 4,431,758 shares 
of Common Stock outstanding (4,641,758 shares of Common Stock outstanding if 
the Over-Allotment Option is exercised in full). Of these shares, the 
1,400,000 Shares offered hereby (1,610,000 shares if the Over-Allotment 
Option is exercised in full) will be freely tradeable without further 
registration under the Securities Act. With respect to the remainder of such 
shares, all officers and directors of the Company and current stockholders 
have agreed not to publicly sell, or otherwise dispose of any securities of 
the Company for a period of 12 months from the date of this Prospectus 
without the Underwriter's prior written consent except (i) shares issued 
pursuant to the Over-Allotment Option, (ii) the Underwriter's Options and the 
Common Stock underlying such options, (iii) the issuance of Common Stock 
underlying warrants and options outstanding 

                                      42 

<PAGE>

prior to this Offering, (iv) the issuance of shares of Common Stock 
underlying the Bridge Warrants, (v) the issuance of shares of Common Stock or 
options to purchase shares of Common Stock under the Plan and the issuance of 
shares of Common Stock upon exercise of such options, and (vi) the issuance 
of any securities in connection with any acquisition which is approved by a 
majority of the independent directors of the Company. Notwithstanding the 
foregoing, up to 30% of the shares of Common Stock of each stockholder may be 
sold by such stockholders at any time commencing six months from the date of 
this Prospectus without the Underwriter's consent in the event that the last 
sales price for the Common Stock on its principal exchange has been at least 
200% of the initial public offering price for a period of 20 consecutive 
trading days ending within five days of the date of such sale, and such sale 
is completed at a price in excess of 200% of the initial public offering 
price. See "Underwriting." 

   All of the presently outstanding 3,031,758 shares of Common Stock are, and 
the 456,250 shares of Common Stock issuable upon exercise of the Bridge 
Warrants and the 468,242 shares issuable upon exercise of the Technologies 
Warrants will be, "restricted securities" within the meaning of Rule 144 and, 
if held for at least two years, would be eligible for sale in the public 
market in reliance upon, and in accordance with, the provisions of Rule 144 
following the expiration of such two-year period. In general, under Rule 144 
as currently in effect, a person or persons whose shares are aggregated, 
including a person who may be deemed to be an "affiliate" of the Company as 
that term is defined under the Securities Act, would be entitled to sell 
within any three-month period a number of shares beneficially owned for at 
least two years that does not exceed the greater of (i) 1% of the then 
outstanding shares of Common Stock, or (ii) the average weekly trading volume 
in the Common Stock during the four calendar weeks preceding such sale. Sales 
under Rule 144 are also subject to certain requirements as to the manner of 
sale, notice and the availability of current public information about the 
Company. However, a person who is not deemed to have been an affiliate of the 
Company during the 90 days preceding a sale by such person and who has 
beneficially owned shares of Common Stock for at least three years may sell 
such shares without regard to the volume, manner of sale, or notice 
requirements of Rule 144. Beginning 90 days after the date of this 
Prospectus, approximately 2,768,600 shares will be available for sale in 
reliance upon Rule 144. 

   Prior to this Offering, there has been no public market for the Company's 
securities. Following this Offering, the Company cannot predict the effect, 
if any, that sales of shares of Common Stock pursuant to Rule 144 or 
otherwise, or the availability of such shares for sale, will have on the 
market price prevailing from time to time. In addition, sales by the current 
stockholders of a substantial number of shares of Common Stock in the public 
market could materially adversely affect prevailing market prices for the 
Common Stock. The availability for sale of a substantial number of shares of 
Common Stock acquired through the exercise of the Underwriter's Options, the 
Warrants or any options under the Plan could also materially adversely affect 
prevailing market prices for the Common Stock. See "Risk Factors--Future 
Sales of Restricted Securities." 

   Up to 140,000 additional shares of Common Stock may be purchased by the 
Underwriter through the exercise of the Underwriter's Options during the 
period commencing on the date of the closing of this Offering and terminating 
on the fifth anniversary of such date. The Holders of the Underwriter's 
Options have certain demand and "piggyback" registration rights as to such 
options and the underlying shares of Common Stock. Such options and any and 
all shares of Common Stock purchased upon the exercise of the Underwriter's 
Options may be freely tradeable, provided that the Company satisfies certain 
securities registration and qualification requirements in accordance with the 
terms of the Underwriter's Options. See "Underwriting." 

   Up to 456,250 shares of Common Stock may be purchased by the holders of 
the Bridge Warrants. Such holders have certain "piggyback" registration 
rights as to such shares commencing two years after the date of this 
Offering. Such shares will be freely tradeable upon such registration. 

                                      43

                                  UNDERWRITING

   The Underwriter has agreed, subject to the terms and conditions of the 
Underwriting Agreement (the form of which has been filed as an exhibit to the 
Registration Statement), to purchase from the Company all of the Shares 
offered. The Underwriting Agreement provides that the obligations of the 
Underwriter are subject to certain conditions precedent and that the 
Underwriter shall be obligated to purchase all of the Shares if any are 
purchased by the Underwriter. 

   The Underwriter has advised the Company that the Underwriter proposes to 
offer the Shares offered hereby to the public at the offering price set forth 
on the cover page of this Prospectus and that the Underwriter may allow to 
certain dealers, who are members of the National Association of Securities 
Dealers (the "NASD"), concessions of not in excess of $ per Share, of which 
not in excess of $ may be reallowed to other dealers who are members of the 
NASD. After the commencement of this Offering, the public offering price, the 
concessions and the reallowance may be changed. 

   The Company has granted an option to the Underwriter, exercisable during 
the 45-day period after the effective date of this Prospectus, to purchase up 
to an aggregate of 210,000 additional Shares at the public offering price, 
less the underwriting discounts and commissions. The Underwriter may exercise 
such option only for the purpose of covering Over-Allotments made in 
connection with the sale of the Common Stock offered hereby. 

   The Company has agreed to indemnify the Underwriter against certain 
liabilities in connection with the Registration Statement, including 
liabilities under the Securities Act. Insofar as indemnification for 
liabilities arising under the Securities Act may be permitted to the 
Underwriter, the Underwriter has been advised that, in the opinion of the 
Commission such indemnification is against public policy as expressed in the 
Securities Act and is, therefore unenforceable. 

   The Company has agreed to pay the Underwriter a non-accountable expense 
allowance of 3% of the aggregate offering price of the Shares offered hereby 
(including any Shares purchased pursuant to the Over- Allotment Option), of 
which $35,000 has been paid to date. 

   The Company has also agreed to sell to the Underwriter, or its designees, 
Underwriter's Options to purchase 140,000 shares at a price of $.001 per 
option. The Underwriter's Options will be exercisable for a period of five 
years, commencing on the date of this Prospectus, at an initial per share 
exercise price equal to 120% of the initial public offering price per share. 
The Underwriter's Options cannot be transferred, assigned or hypothecated for 
one year from the date of their issuance, except that they may be assigned, 
in whole or in part, to any successor, officer or partner of the Underwriter 
or its partners or members of the underwriting group. The Underwriter's 
Options may be exercised as to all or a lesser number of shares and will 
contain certain registration rights and antidilution provisions providing for 
appropriate adjustment of the exercise price and number of shares which may 
be purchased upon exercise, upon the occurrence of certain events. See "Risk 
Factors--Effect of Previously Issued Options, Warrants and Underwriter's 
Options on Stock Price." 

   The Company has agreed that it will, on any two occasions, register the 
securities underlying the Underwriter's Options, the first time at the 
Company's expense. The Company has also agreed, during the seven year period 
commencing on the date of the closing of this Offering, to register on a 
"piggyback" basis, on an unlimited number of occasions, the securities 
underlying the Underwriter's Options whenever the Company files a 
registration statement. Notwithstanding these registration rights, the 
Company will not be required to register the securities underlying the 
Underwriter's Options if it delivers to the holders of the Underwriter's 
Options an opinion of counsel from counsel reasonably acceptable to such 
holders in form and substance reasonably acceptable to such holders that such 
securities are freely transferable without registration.

   The Company has granted to the Underwriter a right of first refusal with
respect to any sale of securities to be made by the Company, its subsidiaries,
affiliates or successors or any of the Company's stockholders owning at least 4%
of the Company's capital stock outstanding as of the date of this Offering,
within three years after the effective date of this Offering. In addition, the
Underwriter will provide financial advisory services with respect to possible
future financings or acquisitions by the Company and related matters. The
Company has also agreed to pay the Underwriter a fee with respect to any merger,
acquisition, joint venture, sale of securities or other business transaction,
with certain exceptions, to which the Company is a party during such two-year
period. Such fee will be equal to a percentage of the consideration paid or
received by the Company in connection with such transaction.

   The Company has also agreed for the five-year period commencing upon 
consummation of this Offering, to nominate and use its best efforts 
(including the solicitation of proxies) to elect one designee of the 
Underwriter to the board of directors of the Company. No designee has been 
chosen as of the date hereof. 

   The foregoing discussion of the material terms and provisions of the 
Underwriting Agreement is qualified in its entirety by reference to the 
detailed provisions of the Underwriting Agreement, the form of which has been 
filed as an exhibit to the Registration Statement on Form SB-2, of which this 
Prospectus forms a part. 

   The Underwriter acted as placement agent in connection with the Bridge 
Financing. In connection therewith, the Underwriter received sales 
commissions of $182,500 in the aggregate, was reimbursed a total of $34,000 
for certain expenses (including attorneys' fees) and was issued a total of 
45,625 warrants which are identical to the Bridge Warrants (the "Placement 
Agent's Warrants"). The Underwriter has agreed to relinquish the Placement 
Agent's Warrants upon the consummation of this Offering. 

   The Company and its directors, officers and the holders of all of the 
Company's outstanding Common Stock have agreed with the Underwriter not to 
sell, contract to sell or otherwise dispose of any of the Company's 
securities held by them for a period of 12 months following the date of this 
Prospectus without the prior written consent of the Underwriter, except for 
certain exceptions and under certain circumstances. See "Shares Eligible For 
Future Sale." 

   Prior to this Offering, there has been no public market for the Common 
Stock. Consequently, the public Offering price of the Shares has been 
determined by arms-length negotiation between the Company and the Underwriter 
and does not necessarily bear any relationship to the Company's book value, 
assets, past operating results, financial condition, or other established 
criteria of value. Factors considered in determining such price included an 
assessment of the Company's recent financial results and current financial 
condition, future prospects of the Company, the qualifications of the 
Company's management, and other relevant factors.

INDEPENDENT AUDITORS' REPORT 

The Board of Directors and Stockholders Thinking Tools, Inc.: 

   We have audited the accompanying balance sheet of Thinking Tools, Inc. 
(the Company) as of December 31, 1995, and the related statements of 
operations, stockholders' deficit, and cash flows for each of the years in 
the two-year period ended December 31, 1995. These financial statements are 
the responsibility of the Company's management. Our responsibility is to 
express an opinion on these financial statements based on our audits. 

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

   In our opinion, the financial statements referred to above present fairly, 
in all material respects, the financial position of Thinking Tools, Inc. as 
of December 31, 1995, and the results of its operations and its cash flows 
for each of the years in the two-year period ended December 31, 1995 in 
conformity with generally accepted accounting principles. 

   The accompanying financial statements have been prepared assuming that the 
Company will continue as a going concern. As discussed in Note 1 to the 
financial statements, the Company has suffered recurring losses from 
operations and has a net capital deficiency that raise substantial doubt 
about its ability to continue as a going concern. Management's plans in 
regard to these matters are described in Note 13. The financial statements do 
not include any adjustments that might result from the outcome of this 
uncertainty. 

                                                         KPMG Peat Marwick LLP

                        NOTES TO FINANCIAL STATEMENTS 
           (Information as of June 30, 1996 and for the six months 
                  ended June 30, 1995 and 1996 is unaudited) 

(1)  Summary of Significant Accounting Policies 

   Thinking Tools, Inc. (the Company) was incorporated in California in 1993 and
develops agent-based, adaptive PC-based business simulation software that has a
broad range of potential applications. A majority of the Company's outstanding
common stock is held by Thinking Technologies, L.P. In June 1996, the Board of
Directors authorized a 4.1225-for-1 stock split for all outstanding shares of
the Company's common stock.

   In August 1996, the Company reincorporated in the state of Delaware by 
merging with and into a wholly-owned subsidiary which was incorporated in 
Delaware in August 1996, with authorized capital consisting of 20,000,000 
shares of $0.001 par value common stock and 3,000,000 shares of $0.001 par 
value preferred stock. Pursuant to such merger each outstanding share of the 
Company's common stock was exchanged for .7462 shares of common stock. 

   The accompanying financial statements and notes have been restated to give 
effect to the stock splits and reincorporation. 

   Basis of Presentation 

   The accompanying financial statements have been prepared assuming that the 
Company will continue as a going concern. The Company has suffered recurring 
losses from operations and has a net capital deficiency that raise 
substantial doubt about its ability to continue as a going concern. 
Management's plans in regard to these matters are described in Note 13. 

   Use of Estimates 

   The preparation of financial statements in conformity with generally 
accepted accounting principles requires management to make estimates and 
assumptions that affect the reported amounts of assets and liabilities and 
disclosure of contingent assets and liabilities at the date of the financial 
statements and reported amounts of revenues and expenses during the reporting 
period. Actual results could differ from those estimates. Significant 
estimates made by management include the stage of completion and the amount 
of costs yet to be incurred on contracts in process. 

   Revenue and Cost Recognition 

   Revenues from fixed-price contracts are recognized using the 
percentage-of-completion method, measured by input measures. Contract costs 
include primarily direct labor and other direct costs. Provisions for 
estimated losses on uncompleted contracts are made in the period in which 
such losses are determined. Changes in job performance, job conditions, and 
estimated profitability may result in revisions to costs and revenues and are 
recognized in the period in which the revisions are determined. Revenues from 
time and materials contracts are recognized as costs are incurred. 

   Property and Equipment 

   Property and equipment are stated at cost less accumulated depreciation 
and amortization. Depreciation is provided using the straight-line method 
over the estimated useful lives of the assets.

                  NOTES TO FINANCIAL STATEMENTS--(Continued) 
           (Information as of June 30, 1996 and for the six months 
                  ended June 30, 1995 and 1996 is unaudited) 

(1)  Summary of Significant Accounting Policies--(Continued) 

Leasehold improvements are amortized over the shorter of the estimated useful 
lives or the underlying lease term. 

   Research and Development 

   Research and development costs are charged to expense as incurred. The 
Company capitalizes software development costs incurred subsequent to the 
establishment of technological feasibility (generally the working model). 
Amounts capitalized to date, net of related valuation allowances, have not 
been material. 

   Net Loss Per Share 

   Net loss per share is computed based on the weighted average number of 
shares of common stock outstanding, dilutive common equivalent shares from 
stock options and warrants using the treasury stock method and convertible 
debt using the if-converted method. In accordance with certain Securities and 
Exchange Commission (SEC) Staff Accounting Bulletins, such computations 
include all common equivalent shares (using the treasury stock method) issued 
within one year of filing of the Company's initial public offering (IPO) as 
if they were outstanding for all periods presented using the anticipated IPO 
price. 

   Unaudited Interim Results 

   The accompanying unaudited financial statements as of June 30, 1996, and 
for the six months ended June 30, 1995 and 1996 have been prepared on 
substantially the same basis as the audited financial statements and, in the 
opinion of the Company's management, include all adjustments, consisting only 
of normal recurring adjustments, necessary for a fair presentation of the 
financial information set forth therein. 

   Recent Accounting Pronouncements 

   In October 1995, the Financial Accounting Standards Board issued Statement 
of Financial Accounting Standards (SFAS) No. 123, Accounting for Stock-Based 
Compensation. SFAS No. 123 will be effective for fiscal years beginning after 
December 15, 1995, and will require that the Company either recognize in its 
financial statements costs related to its employee stock-based compensation 
plans, such as stock option and stock purchase plans, or make pro forma 
disclosures of such costs in a footnote to the financial statements. 

   The Company expects to continue to use the intrinsic value method of 
Accounting Principles Board Opinion No. 25, as allowed under SFAS No. 123, to 
account for all of its employee stock-based compensation plans. Therefore, in 
its financial statements for fiscal 1996, the Company will make the required 
pro forma disclosures in a footnote. SFAS No. 123 is not expected to have a 
material effect on the Company's results of operations or financial position.

   As of December 31, 1995, the Company has net operating loss carryforwards 
of $920,000 which expire for federal and state tax purposes in 2010 and 2000, 
respectively. Federal and California tax laws impose significant restrictions 
on the utilization of net operating loss carryforwards in the event of a 
shift in the ownership of the Company, which constitutes an "ownership 
change" as defined by the Internal Revenue Code, Section 382. The Company 
does not believe an ownership change has occurred.

(8)  Line of Credit 

   On November 1, 1995, the Company entered into an agreement with a bank to 
borrow up to $500,000 under a revolving line of credit secured by the 
Company's accounts receivable. Advances on this line accrued interest at the 
bank's prime rate plus 1.75% (8.75% as of December 31, 1995), until April 
1996, when the rate was increased to the bank's prime rate plus 5% following 
a default by the Company. Amounts outstanding as of December 31, 1995 and 
June 30, 1996 were approximately $79,000 and $52,000, respectively. The bank 
agreement requires the Company, among other things, to maintain minimum 
levels of earnings, tangible net worth, and certain minimum financial ratios. 
The agreement expires September 30, 1996. 

   As of July 31, 1996, the Company was in default of certain provisions of 
the credit agreement. The bank has agreed to waive the exercise of its rights 
under the agreement in return for the Company's commitment to repay the 
entire principal balance by August 31, 1996. No future borrowings will be 
available under the agreement. The amounts outstanding under the agreement 
were repaid as of the closing of the bridge financing. (See Note 13). 

(9)  Long-Term Debt 

   The Company has a note payable to Thinking Technologies, L.P., a related 
party, with a balance of $1,200,000 and $1,380,000 as of December 31, 1995 
and June 30, 1996, respectively. The note bears interest at 10% annually, due 
on September 27, 1999, collateralized by all company assets and the Company's 
common stock owned by its President. Interest is payable semiannually if 
specified gross profit levels are realized; otherwise, interest accrues for 
18 months and is added to principal if not paid within 30 days as of March 
30, 1996. Interest payable of $180,000 was converted to note payable in March 
1996. The note provides for payment if specified debt or equity financing is 
obtained prior to maturity; fair value is not practicable to estimate because 
of the uncertainty of the ultimate results of the terms of the note and the 
lack of available similar financing. Approximately $1,320,000 of the note 
balance was converted into an aggregate of 263,158 shares of Common Stock in 
July 1996. The remaining balance was reclassified to accrued expenses. (See 
Note 13). 

(10) Stockholder's Options 

   As of June 30, 1996, the Company has granted options, outside of the stock 
option plan (See Note 13), to purchase 58,964 shares of common stock at an 
exercise price of $0.79 per share to certain of its directors. In August 
1996, the Company issued to a nonaffiliate options to purchase 15,000 shares 
of the common stock at an exercise price of $1.00 per share. The options 
vested immediately. 

(11) Concentrations of Credit Risk 

   The Company's business is dependent on a few customers, the loss of which 
could have a material effect on the Company. The following schedule 
summarizes past distribution of sales by major customer:

(12) Related Party Transactions 

   The Company had a note payable outstanding with Thinking Technologies, 
L.P., a related party, of approximately $122,000 and $352,000 as of December 
31, 1995 and June 30, 1996, respectively. The note bears interest at 7% 
annually, collateralized by the Company's accounts receivable. The original 
due date was December 31, 1995. The note was paid in full in August 1996 in 
the bridge financing (Note 13). 

(13) Subsequent Events and Pro Forma Financial Information 

   On July 1, 1996, in connection with a series of short-term loans from 
Thinking Technologies, L.P., the Company issued warrants to Thinking 
Technologies, L.P. to purchase 468,242 shares of common stock at an exercise 
price of $1.07 per share, expiring on December 31, 2006. The Company expects 
to record a non-cash interest expense of approximately $350,000 in the 
quarter ending September 30, 1996, in connection with the issuance of these 
warrants. 

   Under the Company's 1996 Stock Option Plan (the Plan), options to purchase 
up to an aggregate of 376,000 shares of common stock may be granted to 
officers, directors, employees or consultants. The Plan provides for issuing 
both incentive stock options, which must be granted at fair market value at 
the date of grant, as determined by the Plan Administrator, and nonqualified 
stock options. Options granted under the Plan are generally immediately 
exercisable, vest over a period determined at the time of grant by the Plan 
Administrator, and must be exercised within 10 years. 

   In August 1996, the Company granted options to purchase 52,000 shares of 
common stock to employees at $.79 per share which vested immediately. The 
Company also granted options to purchase 52,000 shares of common stock at 
$5.00 per share which vest over two years. In addition, the Company granted 
options to purchase 41,036 shares of common stock to members of the Company's 
board of directors at an exercise price of $1.00 per share which vested 
immediately. The Company has recorded non-cash compensation expenses of 
approximately $200,000 in July and August 1996 related to the difference 
between the deemed fair value of the common stock and the exercise price of 
the options at the grant date. 

   On August 28, 1996, the Company closed a bridge financing which provided 
gross proceeds of $1,825,000 to the Company from the issuance of promissory 
notes and warrants to purchase 456,250 shares of common stock. The Company 
repaid $502,000 plus $123,000 of accrued interest related to loans from 
Thinking Technologies, L.P. from a portion of such proceeds. Thinking 
Technologies, L.P. purchased $625,000 aggregate principal amount of such 
notes, which remain outstanding. 

   The warrants to purchase 456,250 shares of the Company's common stock are 
exercisable at a price equal to the lesser of $4.20 per share or 60% of the 
initial public offering price per share, expiring August 2001. In addition, 
the Company issued warrants to purchase 45,625 shares of common stock to the 
Placement Agent at an exercise price equal to the lesser of $4.20 per share 
or 60% of the initial public offering price per share. 

   The Company expects to record a non-cash interest expense of approximately 
$550,000 in connection with the issuance of the warrants issued in the bridge 
financing which will be amortized over the term of the loan, which is 
expected to be repaid out of the proceeds of the proposed public offering.

(13) Subsequent Events and Pro Forma Financial Information--(Continued) 

   Pursuant to a plan of reorganization, in August 1996, Thinking 
Technologies, L.P. converted $1,200,000 aggregate principal amount of 
outstanding indebtedness, plus an aggregate of approximately $120,000 of 
accrued interest (see Note 9), into an aggregate of 263,158 shares of common

Item 26. Recent Sales of Unregistered Securities. 

   In the past three years, the Registrant has made the following sales of 
unregistered securities, all of which sales were exempt from the registration 
requirements of the Securities Act pursuant to Section 4(2) thereof or as 
otherwise indicated herein. 


   In August 1996, the Company, through Barington Capital Group, L.P., acting 
as placement agent, issued and sold 18.25 Units of its securities, each 
consisting of one $100,000 principal amount 10% Senior Note and a 5-year 
Warrant to purchase 25,000 shares of Common Stock at an exercise price equal 
to the lesser of $4.20 per share or 60% of the initial public offering price 
per share, at $100,000 per Unit ($1,825,000, total) solely to accredited 
investors. The Company believes that each issuance and sale of such 
securities was exempt from registration pursuant to Section 4(2) of the 
Securities Act and/or Rule 506 promulgated thereunder. Barington Capital 
Group, L.P. received, for its services, a placement fee of 10% of the gross 
proceeds from the sale of the Units and reimbursement of certain other 
expenses. 


   In August 1996, the Company issued options under its Stock Option Plan. 
The Company believes that the issuance of these options was exempt from 
registration pursuant to Sections 3(b) and 4(2) of the Securities Act and 
Rule 701 promulgated thereunder. 

                                     II-1

   In September 1994, pursuant to the Technologies Agreement, Technologies 
purchased 61.11% of the Company's authorized and issued Common Stock for the 
purchase price of $100,000, and loaned to the Company $1,200,000. In August 
1996, such loan, including accrued interest thereon, was converted to 263,158 
shares of Common Stock. In July 1996, Technologies made additional loans to 
the Company in an aggregate principal amount of $502,000 and received the 
Technologies Warrants to purchase 468,242 shares of Common Stock. In August 
1996, upon the repayment by the Company of such loan, including accrued 
interest thereon, Technologies purchased 6.25 units in the Bridge Financing. 
The Company believes that each such transaction was exempt from registration 
pursuant to Section 4(2) of the Securities Act and/or Rule 506 promulgated 
thereunder. 


   The Company has granted options to purchase an aggregate of 73,964 shares 
of Common Stock to certain members of the Company's board of directors and to 
employees. The Company believes that the issuance of such options was exempt 
from registration pursuant to Sections 3(b) and 4(2) of the Securities Act.

Item 28. Undertakings 

   (a) The undersigned Registrant hereby undertakes that it will: 

    (1) File, during any period in which it offers or sells securities, a 
post-effective amendment to this registration statement: 

                                       II-2 

<PAGE>
 
  (i) Include any prospectus required by section 10(a)(3) of the Securities 
      Act; 

  (ii) Reflect in the prospectus any facts or events which, individually or 
 together, represent a fundamental change in the information in the 
 registration statement; and notwithstanding the foregoing, any increase or 
 decrease in volume of securities offered (if the total dollar value of 
 securities offered (if the total dollar value of securities offered would 
 not exceed that which was registered) and any deviation from the low or high 
 end of the estimated maximum Offering range may be reflected in the form of 
 prospectus filed with the Commission pursuant to Rule 424(b) if, in the 
 aggregate, the changes in the volume and price represent no more than a 20% 
 change in the maximum aggregate Offering price set forth in the "Calculation 
 of Registration Fee" table in the effective registration statement. 

  (iii) Include any additional or changed material information on the plan of 
distribution; 

 (2) For determining liability under the Securities Act, treat each 
post-effective amendment as a new registration statement of the securities 
offered, and the Offering of the securities at that time to be the initial 
bona fide Offering. 

 (3) File a post-effective amendment to remove from registration any of the 
securities that remain unsold at the end of the Offering. 

(b) The Registrant hereby undertakes to provide the Underwriter at the 
closing specified in the Underwriting Agreement certificates in such 
denominations and registered in such names as required by the Underwriter to 
permit prompt delivery to each purchaser. 

(c) Insofar as indemnification for liabilities arising under the Securities 
Act may be permitted to directors, officers, and controlling persons of the 
Registrant pursuant to the foregoing provisions, or otherwise, the Registrant 
has been advised that in the opinion of the Securities and Exchange 
Commission such indemnification is against public policy as expressed in the 
Securities Act and is, therefore, unenforceable. In the event that a claim 
for indemnification against such liabilities (other than the payment by the 
Registrant of expenses incurred or paid by a director, officer, or 
controlling person of the Registrant in the successful defense of any action, 
suit or proceeding) is asserted by such director, officer or controlling 
person in connection with the securities being registered, the Registrant 
will, unless in the opinion of its counsel the matter has been settled by 
controlling precedent, submit to a court of appropriate jurisdiction the 
question whether such indemnification by it is against public policy as 
expressed in the Securities Act and will be governed by the final 
adjudication of such issue. 

(d) The Registrant hereby undertakes that it will: 

 (1) For determining any liability under the Securities Act, treat the 
 information omitted from the form of prospectus filed as part of this 
 registration statement in reliance upon Rule 430A under the Securities Act 
 and contained in a form of prospectus filed by the Registrant under Rule 
 424(b)(1) or (4) or 497(h) under the Securities Act as part of this 
 registration statement as of the time the Securities and Exchange Commission 
 declared it effective. 

 (2) For determining any liability under the Securities Act, treat each 
 post-effective amendment that contains a form of prospectus as a new 
 registration statement relating to the securities offered in the 
 registration statement, and that Offering of the securities at that time as 
 the initial bona fide Offering of those securities.

PROSPECTUS    SUBJECT TO COMPLETION DATE ________________, 199_ 
- ----------               THINKING TECHNOLOGIES, INC. 

   This Prospectus relates to the Offering (the "Offering") by certain 
selling stockholders (the "Selling Stockholders") of 596,250 shares (the 
"Shares") of Common Stock, par value $.001 per share which may be sold from 
time to time by the Selling Stockholders, or by transferees, on or after the 
date of this Prospectus, subject to contractual restrictions which provide 
that such securities may not be sold for a period of 12 months after the 
closing of the Company Offering (defined below) without the prior written 
consent of Barington Capital Group, L.P., the underwriter of the Company 
Offering (the "Underwriter"). See "Certain Transactions," "Risk Factors-- 
Shares Eligible for Future Sale; Registration Rights--and Potential Adverse 
Effects from Sales of Selling Stockholder Securities", "Description of 
Securities," "Selling Stockholders" and "Concurrent Sales By Selling 
Stockholders." 


   No underwriting arrangements have been entered into by the Selling 
Stockholders. The distribution of the Shares by the Selling Stockholders may 
be effected from time to time in transactions on the Nasdaq SmallCap Market, 
the Boston Stock Exchange or the Pacific Stock Exchange in negotiated 
transactions, through the writing of options on the Shares, or a combination 
of such methods of sale, at fixed prices that may be changed, at market 
prices prevailing at the time of sale, at prices related to such prevailing 
market prices, or at negotiated prices. The Selling Stockholders may effect 
such transactions by the sale of the Shares to or through broker-dealers, and 
such broker-dealers may receive compensation in the form of discounts, 
concessions or commissions from the Selling Stockholders and/or the 
purchasers of the Shares for whom such broker-dealers may act as agent or to 
whom they may sell as principal, or both. Usual and customary or specifically 
negotiated brokerage fees or commission may be paid by the Selling 
Stockholders in connection with sales of the Shares. No underwriting 
arrangements have been entered into by the Selling Stockholders. 

   The Selling Stockholders and intermediaries through whom the Shares are 
sold may be deemed "underwriters" within the meaning of the Securities Act of 
1933, as amended (the "Act"), with respect to the securities offered and any 
profits realized or commissions received may be deemed underwriting 
compensation. 

   The Company will not receive any proceeds from sales of the Shares. See 
"Selling Stockholders." 

   A registration statement under the Act has been filed with the Securities 
and Exchange Commission with respect to an underwritten public offering on 
behalf of the Company of 1,400,000 shares of Common Stock, plus up to 210,000 
shares which may be offered pursuant to the exercise of the Underwriter's 
over-allotment option (the "Company Offering"). See "Concurrent Sales By 
Company." 

   AN INVESTMENT IN THE SECURITIES OFFERED HEREBY INVOLVES A HIGH DEGREE OF 
RISK AND IMMEDIATE SUBSTANTIAL DILUTION AND SHOULD BE CONSIDERED CAREFULLY 
AND ONLY BY PERSONS WHO CAN AFFORD THE LOSS OF THEIR ENTIRE INVESTMENT. SEE 
"RISK FACTORS" BEGINNING ON PAGE 8 HEREIN. 

   THESE SECURITIES HAVE NOT BEEN APPROVED OR DISAPPROVED BY THE SECURITIES 
AND EXCHANGE COMMISSION OR ANY STATE SECURITIES COMMISSION NOR HAS THE 
SECURITIES AND EXCHANGE COMMISSION OR ANY STATE SECURITIES COMMISSION PASSED 
UPON THE ACCURACY OR ADEQUACY OF THIS PROSPECTUS. ANY REPRESENTATION TO THE 
CONTRARY IS A CRIMINAL OFFENSE.

been filed by the Company with the Securities and Exchange Commission with 
respect to an underwritten public offering by the Company of 1,400,000 shares 
of Common Stock, plus 210,000 shares which may be offered pursuant to 
exercise of the Underwriter's over-allotment option. 

   Concurrent sales of securities by both the Company and by the Selling 
Stockholders would likely have an adverse effect on the market price of the 
Common Stock. The Shares are subject to contractual restrictions upon resale 
with the Underwriter. See "Selling Stockholders--Lock-Up Arrangements", "Risk 
Factors--Shares Eligible for Future Sale; Registration Rights--and Potential 
Adverse Effects from Sales of Selling Stockholder Securities" and 
"Description of Securities."

Lock-Up Arrangements 

   The Selling Stockholders have agreed prior to the closing of the Company 
Offering that they will not publicly sell, offer to sell, contract to offer 
to sell, transfer, assign or pledge any of the Shares which are being 
registered on their behalf by the Registration Statement of which this 
Prospectus forms a part, for a period of 12 months from the closing of the 
Company Offering without the prior written consent of the Underwriter. See 
"Risk Factors--Shares Available for Future Sale and Potential Adverse Effects 
from Sales of Selling Stockholder Securities", "Description of Securities", 
and "Certain Relationships and Related Transactions." 

Plan of Distribution 

   The distribution of the Shares by the Selling Stockholders may be effected 
from time to time in transactions on the Nasdaq, the Boston Stock Exchange or 
the Pacific Stock Exchange, in negotiated transactions, through the writing 
of options on the Shares, or a combination of such methods of sale, at fixed 
prices that may be changed, at market prices prevailing at the time of the 
sale, at prices related to such prevailing market prices or at negotiated 
prices. The Selling Stockholders may effect such transactions by the sale of 
the Shares to or through broker- dealers, and such broker-dealers may receive 
compensation in the form of discounts, concessions or commissions from the 
Selling Stockholders and/or the purchasers of the Shares for whom such 
broker-dealers may act as agent or to whom they may sell as principal, or 
both. Usual and customary or specifically negotiated brokerage fees or 
commissions may be paid by the Selling Stockholders in connection with sales 
of the Shares. No underwriting arrangements have been entered into by the 
Selling Stockholders. 

                                    Alt-4 

<PAGE>
 
     The Selling Stockholders and intermediaries through whom the Shares are
sold may be deemed "underwriters" without the meaning of the Act with respect to
the securities offered and any profits realized or commissions received may be
deemed underwriting compensation. The Company has agreed to indemnify the
Selling Stockholders against certain liabilities, including liabilities under
the Act.

                             THINKING TOOLS, INC.


                            UNDERWRITING AGREEMENT


                                                               August __, 1996


Barington Capital Group, L.P.
888 Seventh Avenue
New York, New York  10019

Dear Sirs:

            The undersigned, Thinking Tools, Inc., a Delaware corporation (the
"Company"), hereby confirms its agreement with you (the "Underwriter") in
connection with the proposed offering of certain of its securities to the public
(the "Offering") as follows:

      1. Introductory. The Company proposes to issue and sell to the Underwriter
1,400,000 shares of Common Stock par value $.001 per share, of the Company (the
"Common Stock"). In addition, solely for the purpose of covering
over-allotments, the Company proposes to grant the Underwriter the option to
purchase from it up to an additional 210,000 shares of Common Stock (the
"Additional Stock") identical to the Common Stock. The Common Stock is more
fully described in the Prospectus referred to below.

      2.  Representations and Warranties of the Company.  The
Company represents and warrants to, and agrees with, the
Underwriter that:

            (a) The Company has filed with the Securities and Exchange
      Commission (the "Commission") under the Securities Act of 1933 , as
      amended (the "Act"), a registration statement, and may have filed one or
      more amendments thereto, on Form SB-2 (Registration No. 333-_____),
      including in such registration statement and each such amendment and
      related Preliminary Prospectus (as hereinafter defined) the registration
      of (i) the 1,400,000 shares of Common Stock (the "Firm Stock"), (ii) the
      Additional Stock, (iii) the Common Stock purchase options referred to in
      Section 5(v) (the "Underwriter's Options"), (iv) the shares of Common
      Stock (the "Underwriter's Stock") issuable upon exercise of the
      Underwriter's Options and (v) the shares of Common Stock (the "Bridge
      Stock") issuable upon exercise of the warrants issued to investors in
      connection with the




<PAGE>



      bridge financing in which the Underwriter acted as placement agent (the
      Firm Stock, the Additional Stock, the Underwriter's Options, the
      Underwriter's Stock and the Bridge Stock are collectively referred to as
      the "Securities"). As used in this Agreement, the term "Registration
      Statement" means such registration statement, as amended, on file with the
      Commission at the time such registration statement becomes effective
      (including the prospectus, financial statements, exhibits, and all other
      documents filed as a part thereof), provided that such Registration
      Statement, at the time it becomes effective, may omit such information as
      is permitted to be omitted from the Registration Statement when it becomes
      effective pursuant to Rule 430A of the General Rules and Regulations
      promulgated under the Act (the "Regulations"), which information ("Rule
      430A Information") shall be deemed to be included in such Registration
      Statement when a final prospectus is filed with the Commission in
      accordance with Rules 430A and 424(b)(1) or (4) of the Regulations; the
      term "Preliminary Prospectus" means each prospectus included in the
      Registration Statement, or any amendments thereto, before it becomes
      effective under the Act, the form of prospectus omitting Rule 430A
      Information included in the Registration Statement when it becomes
      effective, if applicable (the "Rule 430A Prospectus"), and any prospectus
      filed by the Company with your consent pursuant to Rule 424(a) of the
      Regulations; and the term "Prospectus" means the final prospectus included
      as part of the Registration Statement, except that if the prospectus
      relating to the securities covered by the Registration Statement in the
      form first filed on behalf of the Company with the Commission pursuant to
      Rule 424(b) of the Regulations shall differ from such final prospectus,
      the term "Prospectus" shall mean the prospectus as filed pursuant to Rule
      424(b) from and after the date on which it shall have first been used.

            (b) When the Registration Statement becomes effective, and at all
      times subsequent thereto to and including the Closing Date (as defined in
      Section 3) and each Additional Closing Date (as defined in Section 3), and
      during such longer period as the Prospectus may be required to be
      delivered in connection with sales by the Underwriter or a dealer, and
      during such longer period until any post-effective amendment thereto shall
      become effective, the Registration Statement (and any post-effective
      amendment thereto) and the Prospectus (as amended or as supplemented if
      the Company shall have filed with the Commission any amendment or
      supplement to the Registration Statement or the Prospectus) will contain
      all statements which are required to be stated therein in accordance with
      the Act and the Regulations, will comply with the Act and the Regulations,
      and will not contain any untrue statement of a material fact or omit to
      state any material fact required to be stated therein or necessary to make
      the statements therein not

                                    -2-



<PAGE>



      misleading, and no event will have occurred which should have been set
      forth in an amendment or supplement to the Registration Statement or the
      Prospectus which has not then been set forth in such an amendment or
      supplement; if a Rule 430A Prospectus is included in the Registration
      Statement at the time it becomes effective, the Prospectus filed pursuant
      to Rules 430A and 424 (b) (1) or (4) will contain all Rule 430A
      Information and all statements which are required to be stated therein in
      accordance with the Act or the Regulations, will comply with the Act and
      the Regulations, and will not contain any untrue statement of a material
      fact or omit to state any material fact required to be stated therein or
      necessary to make the statements therein not misleading; and each
      Preliminary Prospectus, as of the date filed with the Commission, did not
      include any untrue statement of a material fact or omit to state any
      material fact required to be stated therein or necessary to make the
      statements therein not misleading; except that no representation or
      warranty is made in this Section 2(b) with respect to statements or
      omissions made in reliance upon and in conformity with written information
      furnished to the Company as stated in Section 8(b) with respect to the
      Underwriter by or on behalf of the Underwriter expressly for inclusion in
      any Preliminary Prospectus, the Registration Statement, or the Prospectus,
      or any amendment or supplement thereto.

            (c) Neither the Commission nor the "blue sky" or securities
      authority of any jurisdiction has issued an order (a "Stop Order")
      suspending the effectiveness of the Registration Statement, preventing or
      suspending the use of any Preliminary Prospectus, the Prospectus, the
      Registration Statement, or any amendment or supplement thereto, refusing
      to permit the effectiveness of the Registration Statement, or suspending
      the registration or qualification of any of the Securities, nor has any of
      such authorities instituted or threatened to institute any proceedings
      with respect to a Stop Order.

            (d) Any contract, agreement, instrument, lease, or license required
      to be described in the Registration Statement or the Prospectus has been
      properly described therein. Any contract, agreement, instrument, lease, or
      license required to be filed as an exhibit to the Registration Statement
      has been filed with the Commission as an exhibit to the Registration
      Statement.

            (e) The Company has no subsidiaries (as defined in the Regulations).
      The Company is a corporation duly organized, validly existing, and in good
      standing under the laws of Delaware, with full corporate power and
      authority, and all necessary consents, authorizations, approvals, orders,
      licenses, certificates, and permits of and from, and declarations and
      filings with, all federal, state, local,

                                    -3-



<PAGE>



      and other governmental authorities and all courts and other tribunals, to
      own, lease, license, and use its properties and assets and to carry on the
      business in the manner described in the Prospectus. The Company is duly
      qualified to do business and is in good standing in every jurisdiction in
      which its ownership, leasing, licensing, or use of property and assets or
      the conduct of its business makes such qualification necessary except
      where the failure to be so qualified does not now have and will not in the
      future have a material adverse effect on the operations, business,
      properties, or assets of the Company.

            (f)   As of the Closing of the sale of the Firm Stock,
      the authorized capital stock of the Company consists of 20,000,000 shares
      of Common Stock, of which [3,031,758] shares are outstanding, and
      3,000,000 shares of undesignated Preferred Stock, $.001 par value (the
      "Undesignated Preferred Stock") of which [no] shares are outstanding. Each
      outstanding share of Common Stock is validly authorized, validly issued,
      fully paid, and nonassessable, without any personal liability attaching to
      the ownership thereof has not been issued and is not owned or held in
      violation of any preemptive rights of stockholders. There is no
      commitment, plan, or arrangement to issue, and no outstanding option,
      warrant, or other right calling for the issuance of, any share of capital
      stock of the Company or any security or other instrument which by its
      terms is convertible into, exercisable for, or exchangeable for, capital
      stock of the Company except as may be properly described in the
      Prospectus. There is outstanding no security or other instrument which by
      its terms is convertible into or exchangeable for capital stock of the
      Company, except for (i) options to purchase no more than 376,000 shares of
      Common Stock pursuant to the Company's 1996 Stock Option Plan (the
      "Plan"), which is properly described in the Prospectus, (ii) options to
      purchase no more than 15,000 shares of Common Stock granted outside the
      Plan to a non-affiliate of the Company; (iii) warrants to purchase 456,250
      shares of Common Stock pursuant to the bridge financing in which the
      Underwriter acted as placement agent; (iv) warrants to purchase 468,242
      shares of Common Stock issued to Thinking Technologies, L.P.; all of which
      have been properly described in the Prospectus. There is outstanding no
      indebtedness other than (i) trade payables incurred in the ordinary course
      of business, (ii) certain capital lease obligations and (iii) an aggregate
      principal amount of $1,825,000 currently outstanding on 10% Senior Secured
      Promissory Notes issued pursuant to a bridge financing entered into as of
      August __, 1996, all as properly described in the Prospectus.

            (g) The financial statements of the Company included in the
      Registration Statement and the Prospectus fairly present the financial
      position, the results of operations, and the other information purported
      to be shown therein at the respective dates and for the respective periods
      to which they apply. Such financial statements have been prepared in
      accordance with generally accepted accounting principles (except to the
      extent that certain footnote disclosures regarding any stub period may
      have been omitted in accordance with the applicable rules of the
      Commission under the Securities Exchange Act of 1934, as amended (the
      "Exchange Act")) consistently applied throughout the periods involved, are
      correct and complete, and are in accordance with the books and records of
      the Company. The accountants whose report on the audited financial
      statements is filed with the Commission as a part of the Registration
      Statement are, and during the periods covered by their report(s) included
      in the Registration Statement and the Prospectus were, independent
      certified public accountants within the meaning of the Act and the
      Regulations. No other financial statements are required by Form SB-2 or
      otherwise to be included in the Registration Statement or the Prospectus.
      There has at no time been a material adverse change in the financial
      condition, results of operations, business, properties, assets,
      liabilities, or future prospects of the Company from the latest
      information set forth in the Registration Statement or the Prospectus,
      except as may be properly described in the Prospectus.

            (h) There is no litigation, arbitration, claim, governmental or
      other proceeding (formal or informal), or investigation pending,
      threatened, or, to the knowledge of the Company, in prospect (or any basis
      therefor) with respect to the Company, or any of its operations,
      businesses, properties, assets, liabilities or future prospects, except as
      may be properly described in the Prospectus or such as individually or in
      the aggregate do not now have and will not in the future have a material
      adverse effect upon the operations, business, properties, or assets of the
      Company. The Company is not in violation of, or in default with respect
      to, any law, rule, regulation, order, judgment, or decree except as may be
      properly described in the Prospectus or such as in the aggregate do not
      now have and will not in the future have a material adverse effect upon
      the operations, business, properties, assets, liabilities or future
      prospects, of the Company; nor is the Company required to take any action
      in order to avoid any such violation or default.

            (i) The Company has good and marketable title in fee simple to all
      real properties and good title to all other properties and assets which
      the Prospectus indicates are owned by it, free and clear of all liens,
      security interests, pledges, charges, encumbrances, and mortgages

                                    -5-



<PAGE>



      (except as may be properly described in the Prospectus). No real property
      owned, leased, licensed, or used by the Company lies in an area which is,
      or to the knowledge of the Company will be, subject to zoning, use, or
      building code restrictions which would prohibit, and no state of facts
      relating to the actions or inaction of another person or entity or his or
      its ownership, leasing, licensing, or use of any real or personal property
      exists or will exist which would prevent, the continued effective
      ownership, leasing, licensing, or use of such real property in the
      business of the Company as presently conducted or as the Prospectus
      indicates it contemplates conducting (except as may be properly described
      in the Prospectus).

            (j) The Company is not, nor to the knowledge of the Company is any
      other party, now or expected by the Company to be in violation or breach
      of, or in default with respect to, complying with any material provision
      of any contract, agreement, instrument, lease, license, arrangement, or
      understanding which is material to the Company, and each such contract,
      agreement, instrument, lease, license, arrangement, and understanding is
      in full force and is the legal, valid, and binding obligation of the
      parties thereto and is enforceable as to them in accordance with its
      terms. The Company enjoys peaceful and undisturbed possession under all
      leases and licenses under which it is operating. The Company is not a
      party to or bound by any contract, agreement, instrument, lease, license,
      arrangement, or understanding, or subject to any charter or other
      restriction, which has had or may in the future have a material adverse
      effect on the financial condition, results of operations, business,
      properties, assets, liabilities, or future prospects of the Company. The
      Company is not in violation or breach of, or in default with respect to,
      any term of its certificate of incorporation (or other charter document)
      or by-laws.

            (k) All patents, patent applications, trademarks, trademark
      applications, trade names, service marks, copyrights, franchises, and
      other intangible properties and assets (all of the foregoing being herein
      called "Intangibles") that the Company owns or has pending, or under which
      it is licensed, are in good standing and uncontested. The "Thinking Tools"
      and "WHITEBOARD", names and their related logos are trademarks and service
      marks used by the Company to identify its products, and such trademarks
      and service marks are protected by registration in the name of the Company
      on the principal register in the United States Patent and Trademark
      Office. There is no right under any Intangible necessary to the business
      of the Company as presently conducted or as the Prospectus indicates it
      contemplates conducting (except as may be so described in the Prospectus).
      The Company has not infringed, is not infringing, and has not received
      notice of

                                    -6-



<PAGE>



      infringement with respect to asserted Intangibles of others. To the
      knowledge of the Company, there is no infringement by others of
      Intangibles of the Company. To the knowledge of the Company, there is no
      Intangible of others which has had or may in the future have a materially
      adverse effect on the financial condition, results of operations,

      5.  Covenants of the Company.  The Company covenants that it
will:

            (a) Use its best efforts to cause the Registration Statement to
      become effective as promptly as possible. If the Registration Statement
      has become or becomes effective with a form of prospectus omitting Rule
      430A information, or filing of the Prospectus is otherwise required under
      Rule 424(b), the Company will file the Prospectus, properly completed,
      pursuant to Rule 424(b) within the time period prescribed and will provide
      evidence satisfactory to you of such timely filing.

            (b) Notify you immediately, and confirm such notice in writing, (i)
      when the Registration Statement and any post-effective amendment thereto
      become effective, (ii) of the receipt of any comments from the Commission
      or the "blue sky" or securities authority of any jurisdiction regarding
      the Registration Statement, any post-effective amendment thereto, the
      Prospectus, or any amendment or supplement thereto, and (iii) of the
      receipt of any notification with respect to a Stop Order or the initiation
      or threatening of any proceeding with respect to a Stop Order. The Company
      will use its best efforts to prevent the issuance of any Stop Order and,
      if any Stop Order is issued, to obtain the lifting thereof as promptly as
      possible.

            (c) During the time when a prospectus relating to the Firm Stock and
      the Additional Stock is required to be delivered hereunder or under the
      Act or the Regulations, comply so far as it is able with all requirements
      imposed upon it by the Act, as now existing and as hereafter amended, and
      by the Regulations, as from time to time in force, so far as necessary to
      permit the continuance of sales of or dealings in the Firm Stock or the
      Additional Stock, as the case may be, in accordance with the provisions
      hereof and the Prospectus. If, at any time when a prospectus relating to
      the Firm Stock and the Additional Stock is required to be delivered
      hereunder or under the Act or the Regulations, any event shall have
      occurred as a result of which, in the reasonable opinion of counsel for

                                    -12-



<PAGE>



      the Company or counsel for the Underwriter, the Registration Statement or
      the Prospectus as then amended or supplemented contains any untrue
      statement of a material fact or omits to state any material fact required
      to be stated therein or necessary to make the statements therein not
      misleading, or if, in the opinion of either of such counsel, it is
      necessary at any time to amend or supplement the Registration Statement or
      the Prospectus to comply with the Act or the Regulations, the Company will
      immediately notify you and promptly prepare and file with the Commission
      an appropriate amendment or supplement (in form and substance satisfactory
      to you) which will correct such statement or omission or which will effect
      such compliance and will use its best efforts to have any such amendment
      declared effective as soon as possible.

            (d) Deliver without charge to the Underwriter such number of copies
      of each Preliminary Prospectus as may reasonably be requested by the
      Underwriter and, as soon as the Registration Statement, or any amendment
      thereto, becomes effective or a supplement is filed, deliver without
      charge to you two signed copies of the Registration Statement, including
      exhibits, or such amendment thereto, as the case may be, and two copies of
      any supplement thereto, and deliver without charge to the Underwriter such
      number of copies of the Prospectus, the Registration Statement, and
      amendments and supplements thereto, if any, without exhibits, as you may
      request for the purposes contemplated by the Act.

            (e) Endeavor in good faith, in cooperation with you, at or prior to
      the time the Registration Statement becomes effective, to qualify the Firm
      Stock and any Additional Stock for offering and sale under the "blue sky"
      or securities laws of such jurisdictions as you may designate; provided,
      however, that no such qualification shall be required in any jurisdiction
      where, as a result thereof, the Company would be subject to service of
      general process or to taxation as a foreign corporation doing business in
      such jurisdiction to which it is not then subject. In each jurisdiction
      where such qualification shall be effected, the Company will, unless you
      agree in writing that such action is not at the time necessary or
      advisable, file and make such statements or reports at such times as are
      or may be required by the laws of such jurisdiction.

            (f) Use its best efforts to keep the Prospectus and the Registration
      Statement current and effective by filing post-effective amendments, as
      necessary.

            (g) Make generally available (within the meaning of Section 11(a) of
      the Act and the Regulations) to its security holders as soon as
      practicable, but not later than __________, 1997, an earnings statement

      Stock or other securities of the Company) except as provided in Section 3
      and except for (i) the grant of options to purchase no more than 376,000

            existing, and in good standing under the laws of Delaware with full
            corporate power and authority, and all consents, authorizations,

            state, local, and other governmental authorities and all courts and
            other tribunals necessary, to own, lease, license, and use its
            properties and assets and to conduct its business in the manner
            described in the Prospectus. The Company is duly qualified to do
            business and is in good standing in every jurisdiction in which its
            ownership, leasing, licensing, or use of property and assets or the
            conduct of its business makes such qualification necessary except
            where the failure to be so qualified does not now have and will not
            in the future have a material adverse effect on the operations,
            business, properties, or assets of the Company;

                  (ii) the authorized capital stock of the Company consists of
            20,000,000 shares of Common Stock and 3,000,000 shares of Preferred

            Stock is duly authorized, validly issued, fully paid, and
            nonassessable, without any personal liability attaching to the
            ownership thereof and has not been issued and is not owned or held
            in violation of any preemptive right of stockholders. To the
            knowledge of such counsel, there is no commitment, plan, or
            arrangement to issue, and no outstanding option, warrant, or other
            right calling for the issuance of, any share of capital stock of the
            Company, or any security or other instrument which by its terms is
            convertible into, exercisable for, or exchangeable for, capital
            stock of the Company, except as may be properly described in the
            Prospectus. There is outstanding no security or other instrument
            which by its terms is convertible into or exchangeable for capital
            stock of the Company except as may be properly described in the
            Prospectus;

               (iii) to the knowledge of such counsel, there is no litigation,
            arbitration, claim, governmental or other proceeding (formal or
            informal), or investigation pending, threatened, or in prospect (or
            any basis therefor) with respect to the Company, or its operations,
            business, properties, or assets as individually or in the aggregate
            do not now have and cannot reasonably be expected in the future to
            have a material adverse effect upon the operations, business,
            properties or assets of the Company. To the knowledge of such
            counsel, the Company is not in violation of, or in default with
            respect to, any law, rule, regulation, order, judgment, or decree,
            except as may be properly described in the Prospectus or such as in
            the aggregate do not now have and cannot reasonably be expected in
            the future to have a material adverse effect upon the operations,
            business, properties or assets of the

                                    -19-

            Company, nor is the Company required to take any action
            in order to avoid any such violation or default;

                (iv) to the knowledge of such counsel, neither the Company, nor
            any other party is now or is expected by the Company to be in
            violation or breach of, or in default with respect to, complying
            with any material provision of any contract, agreement, instrument,
            lease, license, arrangement, or understanding known to such counsel
            which is material to the Company;

                  (v) the Company is not in violation or breach of, or in
            default with respect to, any term of its certificate of
            incorporation (or other charter document) or by-laws, as amended;

                (vi) the Company has all requisite corporate power and authority
            to execute, deliver and perform each of the Company Documents. All
            necessary corporate proceedings of the Company have been taken to
            authorize the execution, delivery, and performance by the Company of
            the Company Documents. Each Company Document (excluding any Firm
            Stock or Additional Stock not issued on the date of such opinion)
            has been duly executed and delivered by the Company. Each Company
            Document is or, when executed and delivered by the Company will be,
            the legal, valid, and binding obligation of the Company, and
            (subject to applicable bankruptcy, insolvency, and other laws
            affecting the enforceability of creditors' rights generally) is or
            will be enforceable as to the Company in accordance with its terms.
            No consent, authorization, approval, order, license, certificate, or
            permit of or from, or declaration or filing with, any federal,
            state, local, or other governmental authority or any court or other
            tribunal is required by the Company for the execution, delivery, or
            performance by the Company of any of the Company Documents (except
            filings under the Act which have been made prior to the Closing Date
            and consents or other authorizations, approvals, orders, licenses,
            certificates or permits required or necessary under "blue sky" or
            state securities laws). No consent of any party to any contract,
            agreement, instrument, lease, license, arrangement, or understanding
            to which the Company is a party, or to which any of its properties
            or assets are subject, is required for the execution, delivery, or
            performance of any of the Company Documents; and the execution,
            delivery, and performance of the Company Documents will not violate,
            result in a breach of, conflict with, or (with or without the giving
            of notice or the passage of time or both) entitle any party to
            terminate or call a default under any such contract, agreement,
            instrument, lease, license, arrangement, or understanding, or
            violate or

            result in a breach of any term of the certificate of incorporation
            (or other charter document) or by-laws of the Company, as amended,
            or violate, result in a breach of, or conflict with any law, rule,
            regulation, order, judgment, or decree binding on the Company or to
            which any of its operations, business, properties, or assets are
            subject;

               (vii) the Firm Stock and the Additional Stock are validly
            authorized. Such opinion delivered at the Closing Date or any
            Additional Closing Date shall state that each share of Firm Stock or
            Additional Stock, as the case may be, to be delivered on that date
            is validly issued, fully paid, and nonassessable, with no personal
            liability attaching to the ownership thereof, and is not issued in
            violation of any preemptive rights of stockholders, and the
            Underwriter has received good title to the Firm Stock and any
            Additional Stock purchased by it, from the Company, free and clear
            of all liens, security interests, pledges, charges, encumbrances,
            stockholders' agreements, and voting trusts;

              (viii) the Underwriter's Stock has been duly and validly reserved
            for issuance. Such opinion delivered at the Closing Date shall state
            that the Underwriter's Options have been duly and validly issued and
            delivered. The Underwriter's Stock, when issued and delivered in
            accordance with the terms of the Underwriter's Option Agreement,
            will be validly authorized, validly issued, fully paid, and
            nonassessable, with no personal liability attaching to the ownership
            thereof, and will not have been issued in violation of any
            preemptive rights of stockholders; and the holders of the
            Underwriter's Options will receive good title to the securities
            purchased by them, respectively, free and clear of all liens,
            security interests, pledges, charges, encumbrances, stockholders'
            agreements, and voting trusts;

                (ix)  the Common Stock and the Securities conform
            to all statements relating thereto contained in the
            Registration Statement or the Prospectus;

                  (x) to the knowledge of such counsel, any contract, agreement,
            instrument, lease, or license required to be described in the
            Registration Statement or the Prospectus are described therein and
            such descriptions are correct and complete in all material respects.
            To the knowledge of such counsel, any contract, agreement,
            instrument, lease, or license required to be filed as an exhibit to
            the Registration Statement has been filed with the Commission as an
            exhibit to the Registration Statement;

                (xi) insofar as statements in the Prospectus purport to
            summarize the status of litigation or the provisions of laws, rules,
            regulations, orders, judgments, decrees, contracts, agreements,
            instruments, leases, or licenses, such statements have been prepared
            or reviewed by such counsel and accurately reflect the status of
            such litigation and provisions purported to be summarized and are
            correct in all material respects;

               (xii) to the knowledge of such counsel, the conditions for use of
            Form SB-2 have been satisfied with respect to the Registration
            Statement;

            on the ________ Stock Exchange, subject to official

            registered in the Registration Statement or already been exercised
            or waived, no person or entity has the right to require registration
            of shares of Common Stock or other securities of the Company because
            of the filing or effectiveness of the Registration Statement;

               (xvi) the Registration Statement has become effective under the
            Act. To the knowledge of such counsel, no Stop Order has been issued
            and no proceedings for that purpose have been instituted or
            threatened;

              (xvii) the Registration Statement, any Rule 430A Prospectus, and
            the Prospectus, and any amendment or supplement thereto (other than
            financial statements and other financial data and schedules
            contained therein, as to which such counsel need express no
            opinion), comply as to form in all material respects with the
            requirements of the Act and the Regulations;

             (xviii) such counsel has no reason to believe that any of the
            Registration Statement, any Rule 430A Prospectus, or the Prospectus,
            or any amendment or supplement thereto (other than financial
            statements and other financial data and schedules which are or
            should be contained in any thereof, as to which such counsel need
            express no opinion), contains any untrue statement of a material
            fact or omits to state a material fact required to be stated therein
            or necessary to make the statements therein not misleading;


                                    -22-



<PAGE>



               (xix) to the knowledge of such counsel, since the effective date
            of the Registration Statement, no event has occurred which should
            have been set forth in an amendment or supplement to the
            Registration Statement or the Prospectus which has not been set
            forth in such an amendment or supplement; and

                (xx) nothing has come to the attention of such counsel that
            would lead them to believe that the Registration Statement, at the
            time it became effective or at the Closing Date or Additional
            Closing Date, as the case may be, contained an untrue statement of a
            material fact or omitted to state a material fact required to be
            stated therein or necessary to make the statements therein not
            misleading or that the Prospectus, at the Closing Date or Additional
            Closing Date, as the case may be (unless the term "Prospectus"
            refers to a Prospectus which has been provided to the Underwriter by
            the Company for use in connection with the offering of the
            Securities which differs from the Prospectus on file at the
            Commission at the Closing Date or Additional Closing Date, as the
            case may be, in which case at the time it is first provided to the
            Underwriter for such use), included or includes an untrue statement
            of a material fact or omitted or omits to state a material fact
            necessary in order to make the statements therein, in the light of
            the circumstances under which they were made, not misleading (in
            each case other than the financial statements and supporting
            schedules and notes thereto and other financial or statistical
            information included therein, as to which no opinion need be
            rendered) and such counsel does not know of any amendment to the
            Registration Statement required to be filed;

               (xxi) any right of first refusal, preemptive right, right to
            compensation, or other similar right or option, in connection with
            the Offering, this Agreement, the Underwriter's Options or the
            Consulting Agreement, or any of the transactions contemplated hereby
            or thereby known to such counsel and not contemplated by the
            Offering, this Agreement, the Underwriter's Options or the
            Consulting Agreement has been effectively waived.

In rendering such opinion, counsel for the Company may rely (A) as to matters
involving the application of laws other than the laws of the United States, the
General Corporation Law of the State of Delaware and the laws of the State of
New York, to the extent counsel for the Company deems proper and to the extent
specified in such opinion, upon an opinion or opinions (in form and substance
satisfactory to counsel for the Underwriter) of other counsel, acceptable to
counsel for the Underwriter, familiar with the applicable laws, in which case
the opinion of

                                    -23-

Company and that reliance thereon by counsel for the Company and the Underwriter
is reasonable; (B) may rely as to matters of fact, to the extent they deem
proper, on certificates of responsible officers of the Company; and (C) may rely
to the extent they deem proper, upon written statements or certificates of

that copies of any such statements or certificates shall be delivered to counsel
for the Underwriter.

            (c) On or prior to the Closing Date and any Additional Closing Date,
      as the case may be, the Underwriter shall have been furnished such
      information, documents, certificates, and opinions as it may reasonably
      require for the purpose of enabling it to review the matters referred to
      in Section 7(b), and in order to evidence the accuracy, completeness, or
      satisfaction of any of the representations, warranties, covenants,
      agreements, or conditions herein contained, or as you may reasonably
      request.

            (d) At the Closing Date and any Additional Closing Date, as the case
      may be, you shall have received a certificate of the chief executive
      officer and of the chief financial officer of the Company, dated the
      Closing Date or such Additional Closing Date, as the case may be, to the
      effect that the condition set forth in Section 7(a) has been satisfied,
      that as of the date of this Agreement and as of the Closing Date or such
      Additional Closing Date, as the case may be, the representations and
      warranties of the Company contained herein were and are accurate, and that
      as of the Closing Date or such Additional Closing Date, as the case may
      be, the obligations to be performed by the Company hereunder on or prior
      thereto have been fully performed.

            (e) At the time this Agreement is executed and at the Closing Date
      and any Additional Closing Date, as the case may be, you shall have
      received a letter from KPMG Peat Marwick LLP, certified public
      accountants, dated the date of delivery, and addressed to the Underwriter,

            (f) All proceedings taken in connection with the issuance, sale,
      transfer, and delivery of the Firm Stock and any Additional Stock shall be
      satisfactory in form and substance to you and to counsel for the
      Underwriter, and the Underwriter shall have received from such counsel for
      the Underwriter a favorable opinion, dated as of the Closing Date and the
      Additional Closing Date, as the case may be, with respect to such of the
      matters set forth under Section

                                    -24-

      7(b), and with respect to such other related matters, as you
      may reasonably request.

            (g) The NASD, upon review of the terms of the public offering of the
      Firm Stock and any Additional Stock, shall not have objected to the
      Underwriter's participation in such offering.

            (h) Prior to or on the Closing Date, the Company shall have entered
      into the Underwriter's Option.

            (i) Prior to or on the Closing Date, the Company shall have entered
      into the Consulting Agreement with Barington Capital Group, L.P.

            (j) Prior to or on the Closing Date, the Company shall have provided
      to you copies of the agreements referred to in Section 2(s).

      Any certificate or other document signed by any officer of the Company and
delivered to you or to counsel for the Underwriter shall be deemed a
representation and warranty by such officer individually and by the Company
hereunder to the Underwriter as to the statements made therein. If any condition
to the Underwriter's obligations hereunder to be fulfilled prior to or at the
Closing Date or any Additional Closing Date, as the case may be, is not so
fulfilled, you may terminate this Agreement or, if you so elect, in writing
waive any such conditions which have not been fulfilled or extend the time for
their fulfillment.

      8. Indemnification and Contribution. (a) Subject to the conditions set
      forth below, the Company agrees to indemnify and hold harmless the
      Underwriter, its officers, directors, partners, employees, agents, and
      counsel, and each person, if any, who controls the Underwriter within the
      meaning of Section 15 of the Act or Section 20(a) of the Exchange Act,
      against any and all loss, liability, claim, damage, and expense whatsoever
      (which shall include, for all purposes of this Section 8, but not be
      limited to, attorneys' fees and any and all expense whatsoever incurred in
      investigating, preparing, or defending against any litigation, commenced
      or threatened, or any claim whatsoever and any and all amounts paid in
      settlement of any claim or litigation) as and when incurred arising out
      of, based upon, or in connection with (i) any untrue statement or alleged
      untrue statement of a material fact contained (A) in any Preliminary
      Prospectus, any Rule 430A Prospectus, the Registration Statement, or the
      Prospectus (as from time to time amended and supplemented), or any
      amendment or supplement thereto or (B) in any application or other
      document or communication (in this Section 8 collectively called an
      "application") executed by or on behalf of the Company or based upon
      written information furnished by or on behalf of the Company filed

                                    -25-



<PAGE>



      in any jurisdiction in order to qualify any of the Securities under the
      "blue sky" or securities laws thereof or filed with the Commission or any
      securities exchange; or any omission or alleged omission to state a
      material fact required to be stated therein or necessary to make the
      statements therein not misleading, unless such statement or omission was
      made in reliance upon and in conformity with written information furnished
      to the Company as stated in Section 8(b) with respect to any Underwriter
      by or on behalf of such Underwriter through the Underwriter expressly for
      inclusion in any Preliminary Prospectus, any Rule 430A Prospectus, the
      Registration Statement, or the Prospectus, or any amendment or supplement
      thereto, or in any application, as the case may be, or (ii) any breach of
      any representation, warranty, covenant, or agreement of the Company
      contained in this Agreement. The foregoing agreement to indemnify shall be
      in addition to any liability the Company may otherwise have, including
      liabilities arising under this Agreement.

      If any action is brought against the Underwriter or any of its officers,
directors, partners, employees, agents, or counsel, or any controlling persons
of the Underwriter (an "indemnified party") in respect of which indemnity may be
sought against the Company pursuant to the foregoing paragraph, such indemnified
party or parties shall promptly notify the Company in writing of the institution
of such action (but the failure so to notify shall not relieve the Company from
any liability it may have other than pursuant to this Section 8(a), except to
the extent it may have been prejudiced in any material respect by such failure)
and the Company shall promptly assume the defense of such action, including the
employment of counsel (satisfactory to such indemnified party or parties) and
payment of expenses. Such indemnified party or parties shall have the right to
employ its or their own counsel in any such case, but the fees and expenses of
such counsel shall be at the expense of such indemnified party or parties unless
the employment of such counsel shall have been authorized in writing by the
Company in connection with the defense of such action or the Company shall not
have promptly employed counsel satisfactory to such indemnified party or parties
to have charge of the defense of such action or such indemnified party or
parties shall have reasonably concluded that there may be one or more legal
defenses available to it or them or to other indemnified parties which are
different from or additional to those available to the Company, in any of which
events such fees and expenses shall be borne by the Company and the Company
shall not have the right to direct the defense of such action on behalf of the
indemnified party or parties. Anything in this paragraph to the contrary
notwithstanding, the Company shall not be liable for any settlement of any such
claim or action effected without its written consent, which shall not be
unreasonably withheld. The Company shall not, without the prior written consent
of each indemnified party that is not released as described in this sentence,
settle or compromise any

                                    -26-



<PAGE>



action, or permit a default or consent to the entry of judgment in or otherwise
seek to terminate any pending or threatened action, in respect of which
indemnity may be sought hereunder (whether or not any indemnified party is a
party thereto), unless such settlement, compromise, consent, or termination
includes an unconditional release of each indemnified party from all liability
in respect of such action. The Company agrees promptly to notify the Underwriter
of the commencement of any litigation or proceedings against the Company or any
of its officers or directors in connection with the sale of the [Firm Stock or
the Additional Stock], any Preliminary Prospectus, any Rule 430A Prospectus, the
Registration Statement, or the Prospectus, or any amendment or supplement
thereto, or any application.

            (b) The Underwriter agrees to indemnify and hold harmless the
      Company, each director of the Company, each officer of the Company who
      shall have signed the Registration Statement, and each other person, if
      any, who controls the Company within the meaning of Section 15 of the Act
      or Section 20(a) of the Exchange Act, to the same extent as the foregoing
      indemnity from the Company to the Underwriter in Section 8(a), but only
      with respect to statements or omissions, if any, made in any Preliminary
      Prospectus, any Rule 430A Prospectus, the Registration Statement, or the
      Prospectus (as from time to time amended and supplemented), or any
      amendment or supplement thereto, or in any application in reliance upon
      and in conformity with written information furnished to the Company as
      stated in this Section 8(b) with respect to any Underwriter by or on
      behalf of such Underwriter through the Underwriter expressly for inclusion
      in any Preliminary Prospectus, any Rule 430A Prospectus, the Registration
      Statement, or the Prospectus, or any amendment or supplement thereto, or
      in any application, as the case may be; provided, however, that the
      obligation of each Underwriter to provide indemnity under the provisions
      of this Section 8(b) shall be limited to the amount which represents the
      underwriting discounts received by such Underwriter hereunder. For all
      purposes of this Agreement, the amounts of the selling concession and
      reallowance set forth in the Prospectus constitute the only information
      furnished in writing by or on behalf of any Underwriter expressly for
      inclusion in any Preliminary Prospectus, any Rule 430A Prospectus, the
      Registration Statement, or the Prospectus (as from time to time amended or
      supplemented), or any amendment or supplement thereto, or in any
      application, as the case may be. If any action shall be brought against
      the Company or any other person so indemnified based on any Preliminary
      Prospectus, any Rule 430A Prospectus, the Registration Statement, or the
      Prospectus, or any amendment or supplement thereto, or in any application,
      and in respect of which indemnity may be sought against any Underwriter
      pursuant to this Section 8(b), such Underwriter shall have the rights and
      duties given to the Company, and the Company and each other person

                                    -27-



<PAGE>



      so indemnified shall have the rights and duties given to the indemnified
      parties, by the provisions of Section 8(a).

            (c) To provide for just and equitable contribution, if (i) an
      indemnified party makes a claim for indemnification pursuant to Section
      8(a) or 8(b) (subject to the limitations thereof) but it is found in a
      final judicial determination, not subject to further appeal, that such
      indemnification may not be enforced in such case, even though this
      Agreement expressly provides for indemnification in such case or (ii) any
      indemnified or indemnifying party seeks contribution under the Act, the
      Exchange Act, or otherwise, then the Company (including for this purpose
      any contribution made by or on behalf of any director of the Company, any
      officer of the Company who signed the Registration Statement, and any
      controlling person of the Company), as one entity, and the Underwriter
      (including for this purpose any contribution by or on behalf of an
      indemnified party), as a second entity, shall contribute to the losses,
      liabilities, claims, damages, and expenses whatsoever to which any of them
      may be subject, so that the Underwriter is responsible for the proportion
      thereof equal to the percentage which the underwriting discount per share
      of Firm Stock set forth on the cover page of the Prospectus represents of
      the initial public offering price per share set forth on the cover page of
      the Prospectus and the Company is responsible for the remaining portion;
      provided, however, that if applicable law does not permit such allocation,
      then other relevant equitable considerations such as the relative fault of
      the Company and the Underwriter in connection with the facts which
      resulted in such losses, liabilities, claims, damages, and expenses shall
      also be considered. The relative fault, in the case of an untrue
      statement, alleged untrue statement, omission, or alleged omission, shall
      be determined by, among other things, whether such statement, alleged
      statement, omission, or alleged omission relates to information supplied
      by the Company or by the Underwriter, and the parties' relative intent,
      knowledge, access to information, and opportunity to correct or prevent
      such statement, alleged statement, omission, or alleged omission. The
      Company and the Underwriter agree that it would be unjust and inequitable
      if the respective obligations of the Company and the Underwriter for
      contribution were determined by pro rata or per capita allocation of the
      aggregate losses, liabilities, claims, damages, and expenses (even if the
      Underwriter and the other indemnified parties were treated as one entity
      for such purpose) or by any other method of allocation that does not
      reflect the equitable considerations referred to in this Section 8(c). No
      person guilty of a fraudulent misrepresentation (within the meaning of
      Section 11(f) of the Act) shall be entitled to contribution from any
      person who is not guilty of such fraudulent misrepresentation. For
      purposes of this Section 8(c), each person, if any, who

                                    -28-



<PAGE>



      controls the Underwriter within the meaning of Section 15 of the Act or
      Section 20(a) of the Exchange Act and each officer, director, partner,
      employee, agent, and counsel of the Underwriter shall have the same rights
      to contribution as such Underwriter and each person, if any, who controls
      the Company within the meaning of Section 15 of the Act or Section 20(a)
      of the Exchange Act, each officer of the Company who shall have signed the
      Registration Statement, and each director of the Company shall have the
      same rights to contribution as the Company, subject in each case to the
      provisions of this Section 8(c). In no case shall the Underwriter be
      liable or responsible for any amount in excess of the Underwriting
      discount applicable to the [Firm Stock] purchased by such Underwriter
      hereunder. Anything in this Section 8(c) to the contrary notwithstanding,
      no party shall be liable for contribution with respect to the settlement
      of any claim or action effected without its written consent. This Section
      8(c) is intended to supersede any right to contribution under the Act, the
      Exchange Act, or otherwise.

      9.  [Reserved]

      10. Representations and Agreements to Survive Delivery. All
representations, warranties, covenants, and agreements contained in this
Agreement shall be deemed to be representations, warranties, covenants, and
agreements at the Closing Date and any Additional Closing Date, and such
representations, warranties, covenants, and agreements of the Underwriter and
the Company, including the indemnity and contribution agreements contained in
Section 8, shall remain operative and in full force and effect regardless of any
investigation made by or on behalf of any Underwriter or any indemnified person,
or by or on behalf of the Company or any person or entity which is entitled to
be indemnified under Section 8(b), and shall survive termination of this
Agreement or the delivery of the Firm Stock and any Additional Stock to the
Underwriter. In addition, the provisions of Sections 6, 8, 10, 11, and 13 shall
survive termination of this Agreement, whether such termination occurs before or
after the Closing Date or any Additional Closing Date.

      11.  Effective Date of This Agreement and Termination
Thereof.

            (a) This Agreement shall become effective at 9:30 A.M., New York
      City Time, on the first full business day following the day on which the
      Registration Statement becomes effective or at the time of the initial
      public offering by the Underwriter of the Firm Stock, whichever is
      earlier. The time of the initial public offering shall mean the time,
      after the Registration Statement becomes effective, of the release by you
      for publication of the first newspaper advertisement which is subsequently
      published relating to the shares or the time, after the

                                    -29-



<PAGE>



      Registration Statement becomes effective, when the Firm Stock are first
      released by you for offering by the Underwriter or dealers by letter or
      telegram, whichever shall first occur. You or the Company may prevent this
      Agreement from becoming effective without liability of any party to any
      other party, except as noted below in this Section 11, by giving the
      notice indicated in Section 11(c) before the time this Agreement becomes
      effective.

            (b) In addition to the right to terminate this Agreement pursuant to
      Section 7 hereof, you shall have the right to terminate this Agreement at
      any time prior to the Closing Date or any Additional Closing Date, as the
      case may be, by giving notice to the Company if any domestic or
      international event, act, or occurrence has materially disrupted, or in
      your opinion will in the immediate future materially disrupt, the
      securities markets; or if there shall have been a general suspension of,
      or a general limitation on prices for, trading in securities on the New
      York Stock Exchange, NASDAQ, the American Stock Exchange, or the ________
      Stock Exchange or in the over-the-counter market; or if there shall have
      been an outbreak of major hostilities or other national or international
      calamity; or if a banking moratorium has been declared by a state or
      federal authority; or if a moratorium in foreign exchange trading by major
      international banks or persons has been declared; or if there shall have
      been a material interruption in the mail service or other means of
      communication within the United States; or if the Company shall have
      sustained a material or substantial loss by fire, flood, accident,
      hurricane, earthquake, theft, sabotage, or other calamity or malicious act
      which, whether or not such loss shall have been insured, will, in your
      opinion, make it inadvisable to proceed with the offering, sale, or
      delivery of the Firm Stock or the Additional Stock, as the case may be; or
      if there shall have been such change in the market for securities in
      general or in political, financial, or economic conditions as in your
      judgment makes it inadvisable to proceed with the offering, sale, and
      delivery of the Firm Stock or the Additional Stock, as the case may be, on
      the terms contemplated by the Prospectus.

            (c) If you elect to prevent this Agreement from becoming effective,
      as provided in this Section 11, or to terminate this Agreement pursuant to
      Section 7, or this Section 11, you shall notify the Company promptly by
      telephone, telex, facsimile or telegram, confirmed by letter. If the
      Company elects to prevent this Agreement from becoming effective, as
      provided in this Section 11, the Company shall notify you promptly by
      telephone, telex, facsimile, or telegram, confirmed by letter.

            (d)  Anything in this Agreement to the contrary
      notwithstanding other than Section 11(e), if this Agreement

                                    -30-



<PAGE>



      shall not become effective by reason of an election pursuant to this
      Section 11 or if this Agreement shall terminate or shall otherwise not be
      carried out within the time specified herein by reason of any failure on
      the part of the Company to perform any covenant or agreement or satisfy
      any condition of this Agreement by it to be performed or satisfied, the
      sole liability of the Company to the Underwriter, in addition to the
      obligations the Company assumed pursuant to Section 6, will be to (i)
      reimburse the Underwriter for such out-of-pocket expenses (including the
      fees and disbursements of its counsel) as shall have been incurred by them
      in connection with this Agreement or the proposed offer, sale, and
      delivery of the Firm Stock and any Additional Stock, and the Company
      agrees to pay promptly upon demand the full amount thereof to you less
      amounts previously paid to you in reimbursement of such expenses, and (ii)
      if the Company has elected to prevent this Agreement from becoming
      effective or if you terminate this Agreement pursuant to Section 7, the
      Company and Barington Capital Group, L.P. shall enter into a consulting
      agreement, substantially in the form set forth as an exhibit to the
      Registration Statement, providing that for a period of one year subsequent
      to such termination, if the Company or any subsidiary or affiliate of the
      Company is involved in any private placement, merger, acquisition or sale
      of securities, joint venture or other similar transaction (any of the
      foregoing, a "Subsequent Transaction"), the Company shall pay to the
      Underwriter, a "Lehman formula" fee based on the consideration received by
      the Company in any Subsequent Transaction equal to five percent of the
      first one million dollars of the consideration paid or received by the
      Company (or any stockholder, subsidiary or affiliate) in any Subsequent
      Transaction, four percent of the next million dollars of consideration so
      paid or received, three percent of the next million dollars of
      consideration so paid or received, two percent of the next million dollars
      so paid or received and one percent of any consideration so paid or
      received in excess of four million dollars. For purposes hereof, a
      Subsequent Transaction shall not include a purchase by the Company of
      assets or of stock of another company provided the current stockholders of
      the Company retain control following such purchase and such purchase is
      effected by the Company without the assistance of any other investment
      banking firm.

            (e) Notwithstanding any election hereunder or any termination of
      this Agreement, and whether or not this Agreement is otherwise carried
      out, the provisions of Sections 6, 8, 10, and 15 shall not be in any way
      affected by such election or termination or failure to carry out the terms
      of this Agreement or any part hereof.

      12.  Notices.  All communications hereunder, except as may

         FIFTH. The name and mailing address of the incorporator is Stephen H.

York, New York 10176.

         SIXTH. Election of directors need not be by written ballot.

         SEVENTH. The Corporation reserves the right to amend, alter, change or
repeal any provision contained in this certificate of incorporation, in the
manner now or hereafter prescribed by statute, and all rights conferred upon
stockholders herein are granted subject to this reservation.

         EIGHTH. The Board of Directors is authorized to adopt, amend, or repeal
By-Laws of the Corporation except as and to the extent provided in the By-Laws.

         NINTH. A. Each person who was or is made a party or is threatened to be
made a party to or is otherwise involved in any action, suit, or proceeding,
whether civil, criminal, administrative, or investigative (hereinafter a
"proceeding"), by reason of the fact that he or she is or was a director,
officer, employee, or agent of the Corporation or any of its direct or indirect
subsidiaries or is or was serving at the request of the Corporation as a
director, officer, employee, or agent of any other corporation or of a
partnership, joint venture, trust, or other enterprise, including service with
respect to an employee benefit plan (hereinafter an "indemnitee"), whether the
basis of such proceeding is alleged action in an official capacity as

                                      - 2 -

<PAGE>



a director, officer, employee, or agent or in any other capacity while serving
as a director, officer, employee, or agent, shall be indemnified and held
harmless by the Corporation to the fullest extent authorized by the Delaware
General Corporation Law, as the same exists or may hereafter be amended (but, in
the case of any such amendment, only to the extent that such amendment permits
the Corporation to provide broader indemnification rights than permitted prior
thereto), against all expense, liability, and loss (including attorneys' fees,
judgments, fines, excise or other taxes assessed with respect to an employee
benefit plan, penalties, and amounts paid in settlement) reasonably incurred or
suffered by such indemnitee in connection therewith, and such indemnification
shall continue as to an indemnitee who has ceased to be a director, officer,
employee, or agent and shall inure to the benefit of the indemnitee's heirs,
executors, and administrators; provided, however, that, except as provided in
Paragraph C of this Article NINTH with respect to proceedings to enforce rights
to indemnification, the Corporation shall indemnify any such indemnitee in
connection with a proceeding (or part thereof) initiated by such indemnitee only
if such proceeding (or part thereof) was authorized by the Board of Directors of
the Corporation.
 
                   B. The right to indemnification conferred in Paragraph A of
this Article NINTH shall include the right to be paid by the Corporation the
expenses incurred in defending any proceeding for which such right to
indemnification is applicable in advance of its final disposition (hereinafter
an "advancement of expenses"); provided, however, that, if the Delaware General
Corporation Law requires, an advancement of expenses incurred by an indemnitee
in his or her capacity as a director or officer (and not in any other capacity
in which service was or is rendered by such indemnitee, including, without
limitation, service to an employee benefit plan) shall be made only upon
delivery to the Corporation of an undertaking

                                      - 3 -

<PAGE>


(hereinafter an "undertaking"), by or on behalf of such indemnitee, to repay all
amounts so advanced if it shall ultimately be determined by final judicial
decision from which there is no further right to appeal (hereinafter a "final
adjudication") that such indemnitee is not entitled to be indemnified for such
expenses under this Article NINTH or otherwise.

                   C. The rights to indemnification and to the advancement of
expenses conferred in Paragraphs A and B of this Article NINTH shall be contract
rights. If a claim under Paragraph A or B of this Article NINTH is not paid in
full by the Corporation within sixty days after a written claim has been
received by the Corporation, except in the case of a claim for an advancement of
expenses, in which case the applicable period shall be twenty days, the
indemnitee may at any time thereafter bring suit against the Corporation to
recover the unpaid amount of the claim. If successful in whole or in part in any
such suit, or in a suit brought by the Corporation to recover an advancement of
expenses pursuant to the terms of an undertaking, the indemnitee shall be
entitled to be paid also the expense of prosecuting or defending such suit. In
(i) any suit brought by the indemnitee to enforce a right to indemnification
hereunder (but not in a suit brought by an indemnitee to enforce a right to an
advancement of expenses), it shall be a defense that the indemnitee has not met
any applicable standard for indemnification set forth in the Delaware General
Corporation Law, and (ii) any suit brought by the Corporation to recover an
advancement of expenses pursuant to the terms of an undertaking, the Corporation
shall be entitled to recover such expenses upon a final adjudication that the
indemnitee has not met any applicable standard for indemnification set forth in
the Delaware General Corporation Law. Neither the failure of the Corporation
(including its Board of Directors, independent legal counsel, or its
stockholders) to have made a determination prior to the commencement of such
suit that indemnification of the indemnitee

                                      - 4 -

<PAGE>


is proper in the circumstances because the indemnitee has met the applicable
standard of conduct set forth in the Delaware General Corporation Law, nor an
actual determination by the Corporation (including its Board of Directors,
independent legal counsel, or its stockholders) that the indemnitee has not met
such applicable standard of conduct, shall create a presumption that the
indemnitee has not met the applicable standard of conduct or, in the case of
such a suit brought by the indemnitee, be a defense to such suit. In any suit
brought by the indemnitee to enforce a right to indemnification or to an
advancement of expenses hereunder, or by the Corporation to recover an
advancement of expenses pursuant to the terms of an undertaking, the burden of
proving that the indemnitee is not entitled to be indemnified, or to such
advancement of expenses, under this Article NINTH or otherwise, shall be on the
Corporation.

                   D. The rights to indemnification and to the advancement of
expenses conferred in this Article NINTH shall not be exclusive of any other
right that any person may have or hereafter acquire under any statute, this
certificate of incorporation, by-law, agreement, vote of stockholders or
disinterested directors, or otherwise.

                   E. The Corporation may maintain insurance, at its expense, to
protect itself and any director, officer, employee, or agent of the Corporation
or another corporation, partnership, joint venture, trust, or other enterprise
against any expense, liability, or loss, whether or not the Corporation would
have the power to indemnify such person against such expense, liability, or loss
under the Delaware General Corporation Law.

                   F. The Corporation's obligation, if any, to indemnify any
person who was or is serving as a director, officer, employee, or agent of any
direct or indirect subsidiary of the Corporation or, at the request of the
Corporation, of any other corporation or of a partnership, joint venture, trust,
or other enterprise shall be reduced by any amount such person

                                      - 5 -

<PAGE>


may collect as indemnification from such other corporation, partnership, joint
venture, trust, or other enterprise.

                   G. Any repeal or modification of the foregoing provisions of
this Article NINTH 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.

         TENTH. No director of the Corporation shall be liable to the
Corporation or any of its stockholders for monetary damages for breach of
fiduciary duty as a director, provided that this provision does not eliminate
the liability of the director (i) for any breach of the director's duty of
loyalty to the Corporation or its stockholders, (ii) for acts or omissions not
in good faith or which involve intentional misconduct or a knowing violation of
law, (iii) under Section 174 of Title 8 of the Delaware Code, or (iv) for any
transaction from which the director derived an improper personal benefit. For
purposes of the prior sentence, the term "damages" shall, to the extent
permitted by law, include without limitation, any judgment, fine, amount paid in
settlement, penalty, punitive damages, excise or other tax assessed with respect
to an employee benefit plan, or expense of any nature (including, without
limitation, counsel fees and disbursements). Each person who serves as a
director of the Corporation while this Article TENTH is in effect shall be
deemed to be doing so in reliance on the provisions of this Article TENTH, and
neither the amendment or repeal of this Article TENTH, nor the adoption of any
provision of this Certificate of Incorporation inconsistent with this Article
TENTH, shall apply to or have any effect on the liability or alleged liability
of any director of the Corporation for, arising out of, based upon, or in
connection with any acts or omissions of such director occurring prior to such
amendment, repeal, or adoption of an inconsistent provision. The provisions of
this Article TENTH are cumulative and shall be in addition to and independent

                                      - 6 -

<PAGE>


of any and all other limitations on or eliminations of the liabilities of
directors of the Corporation, as such, whether such limitations or eliminations
arise under or are created by any law, rule, regulation, by-law, agreement, vote
of shareholders or disinterested directors, or otherwise.

         ELEVENTH. Whenever a compromise or arrangement is proposed between the
Corporation and its creditors or any class of them and/or between the
Corporation and its stockholders or any class of them, any court of equitable
jurisdiction within the State of Delaware may, on the application in a summary
way of the Corporation or of any creditor or stockholder thereof or on the
application of any receiver or receivers appointed for the Corporation under the
provisions of Section 291 of Title 8 of the Delaware Code or on the application
of trustees in dissolution or of any receiver or receivers appointed for the
Corporation under the provisions of Section 279 of Title 8 of the Delaware Code
order a meeting of the creditors or class of creditors, and/or of the
stockholders or class of stockholders of the Corporation, as the case may be, to
be summoned in such manner as the said court directs. If a majority in number
representing three-fourths in value of the creditors or class of creditors,
and/or of the stockholders or class of stockholders of the Corporation, as the
case may be, agree to any compromise or arrangement and to any reorganization of
the Corporation as consequence of such compromise or arrangement, the said
compromise or arrangement and the said reorganization shall, if sanctioned by
the court to which the said application has been made, be binding on all the
creditors or class of creditors, and/or on all the stockholders or class of
stockholders, of the Corporation, as the case may be, and also on the
Corporation.

offices, as well as such powers and authorities and such duties as from time to
time may be prescribed by the Board.

         The Board or any transfer agent of the Corporation may direct a new
certificate or certificates representing stock of the Corporation to be issued
in place of any certificate or certificates theretofore issued by the
Corporation, alleged to have been lost, stolen, or destroyed, upon the making of
an affidavit of that fact by the person claiming the certificate to be lost,
stolen, or destroyed. When authorizing such issue of a new certificate or
certificates, the Board (or any transfer agent of the Corporation authorized to
do so by a resolution of the Board) may, in its discretion and as a condition
precedent to the issuance thereof, require the owner of such lost, stolen, or
destroyed certificate or certificates, or his legal representative, to give the
Corporation a bond in such sum as the Board (or any transfer agent so
authorized) shall direct to indemnify the Corporation against any claim that may
be made against the Corporation with respect to the certificate alleged to have
been lost, stolen, or destroyed or the issuance of such new certificates, and
such requirement may be general or confined to specific instances.
        
         Section 6.5 Regulations.

         The Board shall have power and authority to make all such rules and
regulations as it may deem expedient concerning the issue, transfer,

                        THE SHARES ISSUABLE UPON EXERCISE OF THE OPTION
                        REPRESENTED BY THIS CERTIFICATE HAVE BEEN REGISTERED
                        UNDER THE SECURITIES ACT OF 1933, AS AMENDED, PURSUANT
                        TO A REGISTRATION STATEMENT FILED WITH THE SECURITIES
                        AND EXCHANGE COMMISSION. HOWEVER, NEITHER THIS OPTION
                        NOR SUCH SHARES MAY BE OFFERED OR SOLD EXCEPT PURSUANT
                        TO (i) A POST-EFFECTIVE AMENDMENT TO SUCH REGISTRATION
                        STATEMENT, (ii) A SEPARATE REGISTRATION STATEMENT UNDER
                        SUCH ACT, OR (iii) AN EXEMPTION FROM REGISTRATION UNDER
                        SUCH ACT.

                              THE TRANSFER OF THIS
                             OPTION IS RESTRICTED AS
                                DESCRIBED HEREIN.




                             THINKING TOOLS, INC.

                          Option for the Purchase of
                                 Common Stock



No. _                                                           140,000 Shares

      THIS CERTIFIES that, for receipt in hand of $140.00 and other value
received, BARINGTON CAPITAL GROUP, L.P., 888 Seventh Avenue, New York, New York
10019 (the "Holder"), is entitled to subscribe for and purchase from Thinking
Tools, Inc., a Delaware corporation (the "Company"), upon the terms and
conditions set forth herein, at any time or from time to time after the date
hereof, and before 5:00 P.M. on ______ __, 2001, New York time (the "Exercise
Period"), up to 140,000 shares (the "Option Shares") of the Company's common
stock, par value $.001 per share ("Common Stock") at a price of $____ (120% of
the public offering price) per Option Share (the "Exercise Price"). This Option
is the option or one of the options (collectively, including any options issued
upon the exercise or transfer of any such options




<PAGE>



in whole or in part, the "Options") issued pursuant to the Underwriting
Agreement, dated ______ __, 1996, between the Company, Barington Capital Group,
L.P., as underwriter (the "Underwriting Agreement"). As used herein the term
"this Option" shall mean and include this Option and any Option or Options
hereafter issued as a consequence of the exercise or transfer of this Option in
whole or in part. This Option may not be sold, transferred, assigned or
hypothecated until one year after the Effective Date except that it may be
transferred, in whole or in part, to (i) one or more officers or partners of the
Holder (or the officers or partners of any such partner); (ii) any other
underwriting firm or member of the selling group which participated in the
public offering of 1,400,000 shares of the Company's Common Stock which
commenced on ______ __, 1996 (or the officers or partners of any such firm);
(iii) a successor to the Holder, or the officers or partners of such successor;
(iv) a purchaser of substantially all of the assets of the Holder; or (v) by
operation of law; and the term the "Holder" as used herein shall include any
transferee to whom this Option has been transferred in accordance with the
above.

      1. (a) This Option may be exercised during the Exercise Period, as to the
whole or any lesser number of whole Option Shares, by the surrender of this
Option (with the election at the end hereof duly executed) to the Company at its
office at One Lower Ragsdale Drive, I-250, Monterey, CA 93940 (Attention: John
Hiles), or at such other place as is designated in writing by the Company,
together with a certified or bank cashier's check payable to the order of the
Company in an amount equal to the Exercise Price multiplied by the number of
Option Shares for which this Option is being exercised.

            (b) All or any part of this Option may be exercised on a "cashless"
basis, by stating in the exercise notice such intention, and the maximum number
(the "Maximum Number") of shares of Common Stock the optionee elects to purchase
pursuant to such exercise. The number of shares of Common Stock the optionee
shall receive (the "Cashless Exercise Number") shall equal the Maximum Number
minus the quotient that is obtained when the product of the Maximum Number and
the then current Exercise Price is divided by the then Current Market Price per
share (as hereinafter defined).


      2. Upon each exercise of the Holder's rights to purchase Option Shares,
the Holder shall be deemed to be the holder of record of the Option Shares
issuable upon such exercise, notwithstanding that the transfer books of the
Company shall then be closed or certificates representing such Option Shares
shall not then have been actually delivered to the Holder. As soon as
practicable after each such exercise of this Option, the Company shall issue and
deliver to the Holder a certificate or certificates for the Option Shares
issuable upon such exercise, registered in the name of the Holder or its
designee. If this Option

                                   - 2 -




<PAGE>



should be exercised in part only, the Company shall, upon surrender of this
Option for cancellation, execute and deliver a new Option evidencing the right
of the Holder to purchase the balance of the Option Shares (or portions thereof)
subject to purchase hereunder.

      3. Any Options issued upon the transfer or exercise in part of this Option
shall be numbered and shall be registered in an Option Register as they are
issued. The Company shall be entitled to treat the registered holder of any
Option on the Option Register as the owner in fact thereof for all purposes and
shall not be bound to recognize any equitable or other claim to or interest in
such Option on the part of any other person, and shall not be liable for any
registration or transfer of Options which are registered or to be registered in
the name of a fiduciary or the nominee of a fiduciary unless made with the
actual knowledge that a fiduciary or nominee is committing a breach of trust in
requesting such registration or transfer, or with the knowledge of such facts
that its participation therein amounts to bad faith. This Option shall be
transferable only on the books of the Company upon delivery thereof duly
endorsed by the Holder or by his duly authorized attorney or representative, or
accompanied by proper evidence of succession, assignment, or authority to
transfer. In all cases of transfer by an attorney, executor, administrator,
guardian, or other legal representative, duly authenticated evidence of his or
its authority shall be produced. Upon any registration of transfer, the Company
shall deliver a new Option or Options to the person entitled thereto. This
Option may be exchanged, at the option of the Holder thereof, for another
Option, or other Options of different denominations, of like tenor and
representing in the aggregate the right to purchase a like number of Option
Shares (or portions thereof), upon surrender to the Company or its duly
authorized agent. Notwithstanding the foregoing, the Company shall have no
obligation to cause Options to be transferred on its books to any person if, in
the opinion of counsel to the Company, such transfer does not comply with the
provisions of the Securities Act of 1933, as amended (the "Act"), and the rules
and regulations thereunder.

      4. The Company shall at all times reserve and keep available out of its
authorized and unissued Common Stock, solely for the purpose of providing for
the exercise of the Options, such number of shares of Common Stock as shall,
from time to time, be sufficient therefor. The Company covenants that all shares
of Common Stock issuable upon exercise of this Option, upon receipt by the
Company of the full payment therefor, shall be validly issued, fully paid,
nonassessable, and free of preemptive rights.

      5.    (a)   Subject to the provisions of this Section 5, the
Exercise Price in effect from time to time shall be subject to
adjustment, as follows:


                                   - 3 -




<PAGE>



            (i) In case the Company shall at any time after the date hereof (A)
      declare a dividend on the outstanding Common Stock payable in shares of
      its capital stock, (B) subdivide the outstanding Common Stock, (C) combine
      the outstanding Common Stock into a smaller number of shares, or (D) issue
      any shares of its capital stock by reclassification of the Common Stock
      (including any such reclassification in connection with a consolidation or
      merger in which the Company is the continuing corporation), then, in each
      case, the Exercise Price, and the number of shares of Common Stock
      issuable upon exercise of the Options in effect at the time of the record
      date for such dividend or of the effective date of such subdivision,
      combination, or reclassification, shall be proportionately adjusted so
      that the holders of the Options after such time shall be entitled to
      receive the aggregate number and kind of shares which, if such Options had
      been exercised immediately prior to such time, such holders would have
      owned upon such exercise and been entitled to receive by virtue of such
      dividend, subdivision, combination or reclassification, at such aggregate
      price as the holders of such Options would have paid for such exercise
      immediately prior to such time. Such adjustment shall be made successively
      whenever any event listed above shall occur.

            (ii) In case the Company shall issue or fix a record date for the
      issuance to all holders of Common Stock of rights, options, or warrants to
      subscribe for or purchase Common Stock (or securities convertible into or
      exchangeable for Common Stock) at a price per share (or having a
      conversion or exchange price per share, if a security convertible into or
      exchangeable for Common Stock) less than the Current Market Price per
      share of Common Stock (as determined pursuant to Subsection 5(b) hereof)
      on such record date, then, in each case, the Exercise Price shall be
      adjusted by multiplying the Exercise Price in effect immediately prior to
      such record date by a fraction, the numerator of which shall be the number
      of shares of Common Stock outstanding on such record date plus the number
      of shares of Common Stock which the aggregate offering price of the total
      number of shares of Common Stock so to be offered (or the aggregate
      initial conversion or exchange price of the convertible or exchangeable
      securities so to be offered) would purchase at such Current Market Price
      and the denominator of which shall be the number of shares of Common Stock
      outstanding on such record date plus the number of additional shares of
      Common Stock to be offered for subscription or purchase (or into which the
      convertible or exchangeable securities so to be offered are initially
      convertible or exchangeable). Such adjustment shall become effective at
      the close of business on such record date; provided, however, that, to the
      extent the shares of Common Stock (or securities convertible into or
      exchangeable for shares of Common Stock) are not delivered, the Exercise

                                   - 4 -




<PAGE>



      Price shall be readjusted after the expiration of such rights, options, or
      warrants (but only with respect to Options exercised after such
      expiration), to the Exercise Price which would then be in effect had the
      adjustments made upon the issuance of such rights, options, or warrants
      been made upon the basis of delivery of only the number of shares of
      Common Stock (or securities convertible into or exchangeable for shares of
      Common Stock) actually issued. In case any subscription price may be paid
      in a consideration part or all of which shall be in a form other than
      cash, the value of such consideration shall be as determined in good faith
      by the board of directors of the Company, whose determination shall be
      conclusive absent manifest error. Shares of Common Stock owned by or held
      for the account of the Company or any majority-owned subsidiary shall not
      be deemed outstanding for the purpose of any such computation.

            (iii) In case the Company shall distribute to all holders of Common
      Stock (including any such distribution made to the shareholders of the
      Company in connection with a consolidation or merger in which the Company
      is the continuing corporation) evidences of its indebtedness, cash (other
      than any cash dividend which, together with any cash dividends paid within
      the 12 months prior to the record date for such distribution, does not
      exceed 5% of the Current Market Price at the record date for such
      distribution) or assets (other than distributions and dividends payable in
      shares of Common Stock), or rights, options, or warrants to subscribe for
      or purchase Common Stock, or securities convertible into or exchangeable
      for shares of Common Stock (excluding those with respect to the issuance
      of which an adjustment of the Exercise Price is provided pursuant to
      Section 5(a)(ii) hereof), then, in each case, the Exercise Price shall be
      adjusted by multiplying the Exercise Price in effect immediately prior to
      the record date for the determination of shareholders entitled to receive
      such distribution by a fraction, the numerator of which shall be the
      Current Market Price per share of Common Stock on such record date, less
      the fair market value (as determined in good faith by the board of
      directors of the Company, whose determination shall be conclusive absent
      manifest error) of the portion of the evidences of indebtedness or assets
      so to be distributed, or of such rights, options, or warrants or
      convertible or exchangeable securities, or the amount of such cash,
      applicable to one share, and the denominator of which shall be such
      Current Market Price per share of Common Stock. Such adjustment shall
      become effective at the close of business on such record date.

            (iv) In case the Company shall issue shares of Common Stock or
      rights, options, or warrants to subscribe for or purchase Common Stock, or
      securities convertible into or exchangeable for Common Stock (excluding
      shares, rights,

                                   - 5 -

      options, warrants, or convertible or exchangeable securities issued or
      issuable (A) in any of the transactions with respect to which an
      adjustment of the Exercise Price is provided pursuant to Section 5(a)(i),
      5(a)(ii) or 5(a)(iii) above, (B) upon any issuance of securities pursuant
      to the Underwriting Agreement, (C) upon exercise of the Option, (D) upon
      the grant of options to purchase 376,000 shares of Common Stock pursuant
      to the Company's 1996 Stock Option Plan (the "Plan") and (E) upon the
      grant of options to purchase 15,000 shares of Common Stock, outside of the
      Plan, to a non-affiliate of the Company1, at a price per share
      (determined, in the case of such rights, options, warrants, or convertible
      or exchangeable securities, by dividing (x) the total amount received or
      receivable by the Company in consideration of the sale and issuance of
      such rights, options, warrants, or convertible or exchangeable securities,
      plus the minimum aggregate consideration payable to the Company upon
      exercise, conversion, or exchange thereof, by (y) the maximum number of
      shares covered by such rights, options, warrants, or convertible or
      exchangeable securities) lower than the Current Market Price per share of
      Common Stock in effect immediately prior to such issuance, then the
      Exercise Price shall be reduced on the date of such issuance to a price
      (calculated to the nearest cent) determined by multiplying the Exercise
      Price in effect immediately prior to such issuance by a fraction, (a) the
      numerator of which shall be an amount equal to the sum of (A) the number
      of shares of Common Stock outstanding immediately prior to such issuance
      plus (B) the quotient obtained by dividing the aggregate consideration
      received by the Company upon such issuance by such Current Market Price,
      and (b) the denominator of which shall be the total number of shares of
      Common Stock outstanding immediately after such issuance. For the purposes
      of such adjustments, the maximum number of shares which the holders of any
      such rights, options, warrants, or convertible or exchangeable securities
      shall be entitled to initially subscribe for or purchase or convert or
      exchange such securities into shall be deemed to be issued and outstanding
      as of the date of such issuance, and the consideration received by the
      Company for such rights, options, warrants, or convertible or exchangeable
      securities, plus the minimum aggregate consideration or premiums stated in
      such rights, options, warrants or convertible or exchangeable securities
      to be paid for the shares covered thereby. No further adjustment of the
      Exercise Price shall be made as a result of the actual issuance of shares
      of Common Stock on exercise of such rights, options, or warrants or on
      conversion or exchange of such convertible or exchangeable securities. On
      the expiration or the termination of such rights, options, or warrants, or
      the termination of such rights to convert or

      exchange, the Exercise Price shall be readjusted (but only with respect to
      Options exercised after such expiration or termination) to such Exercise
      Price as would have been obtained had the adjustments made upon the
      issuance of such rights, options, warrants, or convertible or exchangeable
      securities been made upon the basis of the delivery of only the number of
      shares of Common Stock actually delivered upon the exercise of such
      rights, options, or warrants or upon the conversion or exchange of any
      such securities; and on any change of the number of shares of Common Stock
      deliverable upon the exercise of any such rights, options, or warrants or
      conversion or exchange of such convertible or exchangeable securities or
      any change in the consideration to be received by the Company upon such
      exercise, conversion, or exchange, including, but not limited to, a change
      resulting from the antidilution provisions thereof, the Exercise Price, as
      then in effect, shall forthwith be readjusted (but only with respect to
      Options exercised after such change) to such Exercise Price as would have
      been obtained had an adjustment been made upon the issuance of such
      rights, options, or warrants not exercised prior to such change, on the
      basis of such change. In case the Company shall issue shares of Common
      Stock or any such rights, options, warrants, or convertible or
      exchangeable securities for a consideration consisting, in whole or in
      part, of property other than cash or its equivalent, then the "price per
      share" and the "consideration received by the Company" for purposes of the
      first sentence of this Section 3(a)(iv) shall be as determined in good
      faith by the board of directors of the Company, whose determination shall
      be conclusive absent manifest error. Shares of Common Stock owned by or
      held for the account of the Company or any majority-owned subsidiary shall
      not be deemed outstanding for the purpose of any such computation.

            (b) For the purpose of any computation under this Section 5 the
Current Market Price per share of Common Stock on any date shall be deemed to be
the average of the daily closing prices for the 30 consecutive trading days
immediately preceding the date in question. The closing price for each day shall
be the last reported sales price regular way or, in case no such reported sale
takes place on such day, the closing bid price regular way, in either case on
the principal national securities exchange (including, for purposes hereof, the
NASDAQ National Market System) on which the Common Stock is listed or admitted
to trading or, if the Common Stock is not listed or admitted to trading on any
national securities exchange, the highest reported bid price for the Common
Stock as furnished by the National Association of Securities Dealers, Inc.
through NASDAQ or a similar organization if NASDAQ is no longer reporting such
information. If on any such date the Common Stock is not listed or admitted to
trading on any national securities exchange and is not quoted by NASDAQ or any

faith by the board of directors of the Company, whose determination shall be
conclusive absent manifest error shall be used.

            (c) No adjustment in the Exercise Price shall be required if such
adjustment is less than $.05; provided, however, that any adjustments which by
reason of this Section 5 are not required to be made shall be carried forward
and taken into account in any subsequent adjustment. All calculations under this
Section 5 shall be made to the nearest cent or to the nearest one thousandth of
a share, as the case may be.

            (d) In any case in which this Section 5 shall require that an
adjustment in the Exercise Price be made effective as of a record date for a
specified event, the Company may elect to defer, until the occurrence of such
event, issuing to the holders of the Option, if any holder has exercised an
Option after such record date, the shares of Common Stock, if any, issuable upon
such exercise over and above the shares of Common Stock, if any, issuable upon
such exercise on the basis of the Exercise Price in effect prior to such
adjustment; provided, however, that the Company shall deliver to such exercising
holder a due bill or other appropriate instrument evidencing such holder's right
to receive such additional shares upon the occurrence of the event requiring
such adjustment.

            (e) Upon each adjustment of the Exercise Price as a result of the
calculations made in Sections 5(a)(ii), 5(a)(iii) or 5(a)(iv) hereof the Option
shall thereafter evidence the right to purchase, at the adjusted Exercise Price,
that number of shares (calculated to the nearest thousandth) obtained by
dividing (A) the product obtained by multiplying the number of shares
purchasable upon exercise of the Option prior to adjustment of the number of
shares by the Exercise Price in effect prior to adjustment of the Exercise Price
by (B) the Exercise Price in effect after such adjustment of the Exercise Price.

            (f) In case of any capital reorganization, other than in the cases
referred to in Section 5(a) hereof, or the consolidation or merger of the
Company with or into another corporation (other than a merger or consolidation
in which the Company is the continuing corporation and which does not result in
any reclassification of the outstanding shares of Common Stock or the
conversion of such outstanding shares of Common Stock into shares of other stock
or other securities or property), or the sale of the property of the Company as
an entirety or substantially as an entirety (collectively such actions being
hereinafter referred to as "Reorganizations"), there shall thereafter be
deliverable upon exercise of any Option (in lieu of the number of shares of
Common Stock theretofore deliverable) the number of shares of stock or other
securities or property to which a holder of the number of shares of Common Stock
which would otherwise have been deliverable upon the exercise of such Option
would have been entitled

                                   - 8 -




<PAGE>



upon such Reorganization if such Option had been exercised in full immediately
prior to such Reorganization. In case of any Reorganization, appropriate
adjustment, as determined in good faith by the board of directors of the
Company, shall be made in the application of the provisions herein set forth
with respect to the rights and interests of Option holders so that the
provisions set forth herein shall thereafter be applicable, as nearly as
possible, in relation to any shares or other property thereafter deliverable
upon exercise of Options. Any such adjustment shall be made by and set forth in
a supplemental agreement between the Company, or any successor thereto, and
[American Stock Transfer & Trust Company] and shall for all purposes hereof
conclusively be deemed to be an appropriate adjustment. The Company shall not
effect any such Reorganization, unless upon or prior to the consummation thereof
the successor corporation, or if the Company shall be the surviving corporation
in any such Reorganization and is not the issuer of the shares of stock or other
securities or property to be delivered to holders of shares of the Common Stock
outstanding at the effective time thereof, then such issuer, shall assume by
written instrument the obligation to deliver to the registered holder of the
Options such shares of stock, securities, cash or other property as such holder
shall be entitled to purchase in accordance with the foregoing provisions. In
the event of sale or conveyance or other transfer of all or substantially all of
the assets of the Company as a part of a plan for liquidation of the Company,
all rights to exercise any Option shall terminate 30 days after the Company
gives written notice to each registered holder of a Option Certificate that such
sale or conveyance of other transfer has been consummated.

            (g) In case of any reclassification or change of the shares of
Common Stock issuable upon exercise of the Options (other than a change in par
value or from no par value to a specified par value, or as a result of a
subdivision or combination, but including any change in the shares into two or
more classes or series of shares), the holders of the Options shall have the
right thereafter to receive upon exercise of the Options solely the kind and
amount of shares of stock and other securities, property, cash, or any
combination thereof receivable upon such reclassification or change by a holder
of the number of shares of Common Stock for which the Options might have been
exercised immediately prior to such reclassification or change. Thereafter,
appropriate provision shall be as nearly equivalent as practicable to the
adjustments in Section 5. The above provisions of this subsection 5(a) shall
similarly apply to successive reclassifications and changes of shares of Common
Stock.

            (h) Whenever the Exercise Price is adjusted as provided in this
Section 5, the Company will promptly obtain a certificate of a firm of
independent public accountants of recognized standing selected by the board of
directors (who may be the regular auditors of the Corporation) setting forth the

                                   - 9 -




<PAGE>



exercise price as so adjusted and a brief statement of the facts accounting for
such adjustment, and will make available a brief summary thereof to the holders
of the Option Certificates, at their addresses listed on the register maintained
for the purpose by the Company.

            (i) Whenever any adjustment is made pursuant to this Section 5, the
Company shall cause notice of such adjustment to be mailed to each registered
holder of an Option Certificate within 15 Business Days (as hereinafter defined)
thereafter, such notice to include in reasonable detail (i) the events
precipitating the adjustment, (ii) the computation of any adjustments, and (iii)
the Exercise Price, the number of shares or the securities or other property
purchasable upon exercise of each Option after giving effect to such adjustment.
For purposes hereof, "Business Day" shall mean any day other than a Saturday, a
Sunday, or a day on which banking institutions in the State of New York are
authorized or obligated by law or executive order to close.

            (j) Irrespective of any adjustments pursuant to this Section 5,
Option Certificates theretofore or thereafter issued need not be amended or
replaced, but certificates thereafter issued shall bear an appropriate legend or
other notice of any adjustments.

            (k) The Company shall not be required upon the exercise of any
Option to issue fractional shares of Common Stock which may result from
adjustments in accordance with this Section 5 to the Exercise Price or number of
shares of Common Stock purchasable under each Option. If more than one Option is
exercised at one time by the same registered holder, the number of full shares
of Common Stock which shall be deliverable shall be computed based on the number
of shares deliverable in exchange for the aggregate number of Options exercised.
With respect to any final fraction of a share called for upon the exercise of
any Option or Options, the Company shall pay a cash adjustment in respect of
such final fraction in an amount equal to the same fraction of the Current
Market Price of a share of Common Stock calculated in accordance with Subsection
5(b).

      6. (a) In case of any consolidation with or merger of the Company with or
into another corporation (other than a merger or consolidation in which the
Company is the surviving or continuing corporation), or in case of any sale,
lease, or conveyance to another corporation of the property and assets of any
nature of the Company as an entirety or substantially as an entirety, such
successor, leasing, or purchasing corporation, as the case may be, shall (i)
execute with the Holder an agreement providing that the Holder shall have the
right thereafter to receive upon exercise of this Option solely the kind and
amount of shares of stock and other securities, property, cash, or any
combination thereof receivable upon such consolidation, merger, sale, lease, or
conveyance by a holder of the number of shares of Common Stock for which this
Option might have been exercised immediately prior

                                   - 10 -




<PAGE>



to such consolidation, merger, sale, lease, or conveyance and (ii) make
effective provision in its certificate of incorporation or otherwise, if
necessary, to effect such agreement. Such agreement shall provide for
adjustments which shall be as nearly equivalent as practicable to the
adjustments provided for in Section 5.

            (b) In case of any reclassification or change of the shares of
Common Stock issuable upon exercise of this Option (other than a change in par
value or from no par value to a specified par value, or as a result of a
subdivision or combination, but including any change in the shares into two or
more classes or series of shares), or in case of any consolidation or merger of
another corporation into the Company in which the Company is the continuing
corporation and in which there is a reclassification or change (including a
change to the right to receive cash or other property) of the shares of Common
Stock (other than a change in par value, or from no par value to a specified par
value, or as a result of a subdivision or combination, but including any change
in the shares into two or more classes or series of shares), the Holder shall
have the right thereafter to receive upon exercise of this Option solely the
kind and amount of shares of stock and other securities, property, cash, or any
combination thereof receivable upon such reclassification, change,
consolidation, or merger by a holder of the number of shares of Common Stock for
which this Option might have been exercised immediately prior to such
reclassification, change, consolidation, or merger. Thereafter, appropriate
provision shall be made for adjustments which shall be as nearly equivalent as
practicable to the adjustments in Section 5.

            (c) The above provisions of this Section 6 shall similarly apply to
successive reclassifications and changes of shares of Common Stock and to
successive consolidations, mergers, sales, leases, or conveyances.

      7.    In case at any time the Company shall propose:

            (a) to pay any dividend or make any distribution on shares of Common
Stock in shares of Common Stock or make any other distribution (other than
regularly scheduled cash dividends which are not in a greater amount per share
than the most recent such cash dividend) to all holders of Common Stock; or

            (b) to issue any rights, warrants, or other securities to all
holders of Common Stock entitling them to purchase any additional shares of
Common Stock or any other rights, warrants, or other securities; or

            (c) to effect any reclassification or change of outstanding shares
of Common Stock, or any consolidation, merger, sale, lease, or conveyance of
property, described in Section 6; or


                                   - 11 -




<PAGE>



            (d)   to effect any liquidation, dissolution, or
winding-up of the Company; or

            (e)   to take any other action which would cause an
adjustment to the Exercise Price;

then, and in any one or more of such cases, the Company shall give written
notice thereof, by registered mail, postage prepaid, to the Holder at the
Holder's address as it shall appear in the Option Register, mailed at least 15
days prior to (i) the date as of which the holders of record of shares of Common
Stock to be entitled to receive any such dividend, distribution, rights,
warrants, or other securities are to be determined, (ii) the date on which any
such reclassification, change of outstanding shares of Common Stock,
consolidation, merger, sale, lease, conveyance of property, liquidation,
dissolution, or winding-up is expected to become effective, and the date as of
which it is expected that holders of record of shares of Common Stock shall be
entitled to exchange their shares for securities or other property, if any,
deliverable upon such reclassification, change of outstanding shares,
consolidation, merger, sale, lease, conveyance of property, liquidation,
dissolution, or winding-up, or (iii) the date of such action which would require
an adjustment to the Exercise Price pursuant to Section 5 hereof.

      8. The issuance of any shares or other securities upon the exercise of
this Option, and the delivery of certificates or other instruments representing
such shares or other securities, shall be made without charge to the Holder for
any tax or other charge in respect of such issuance. The Company shall not,
however, be required to pay any tax which may be payable in respect of any
transfer involved in the issue and delivery of any certificate in a name other
than that of the Holder and the Company shall not be required to issue or
deliver any such certificate unless and until the person or persons requesting
the issue thereof shall have paid to the Company the amount of such tax or shall
have established to the satisfaction of the Company that such tax has been paid.

      9. (a) If, at any time prior to August __, 2003 (seven years from the
"Effective Date", as such term is defined in the Underwriting Agreement), the
Company shall file a registration statement (other than on Form S-4, Form S-8,
or any successor form) with the Securities and Exchange Commission (the
"Commission") while this Option or any Underwriter's Securities (as hereinafter
defined) are outstanding, the Company shall give all the then holders of this
Option or any Underwriter's Securities (collectively, the "Eligible Holders") at
least 45 days prior written notice of the filing of such registration statement.
If requested by any Eligible Holder in writing within 30 days after receipt of
any such notice, the Company shall, at the Company's sole expense (other than
the fees and disbursements of counsel for the Eligible Holders and the
underwriting discounts, if any, payable in respect of the Underwriter's

                                   - 12 -




<PAGE>



Securities sold by any Eligible Holder), register or qualify all or, at each
Eligible Holder's option, any portion of the Underwriter's Securities of any
Eligible Holders who shall have made such request, concurrently with the
registration of such other securities, all to the extent requisite to permit the
public offering and sale of the Underwriter's Securities through the facilities
of all appropriate securities exchanges and the over-the-counter market, and
will use its best efforts through its officers, directors, auditors, and counsel
to cause such registration statement to become effective as promptly as
practicable. Notwithstanding the foregoing, if the managing underwriter of any
such offering shall advise the Company in writing that, in its opinion, the
distribution of all or a portion of the Underwriter's Securities requested to be
included in the registration concurrently with the securities being registered
by the Company would materially adversely affect the distribution of such
securities by the Company for its own account, then any Eligible Holder who
shall have requested registration of his or its Underwriter's Securities shall
delay the offering and sale of such Underwriter's Securities (or the portions
thereof so designated by such managing underwriter) for such period, not to
exceed 90 days (the "Delay Period"), as the managing underwriter shall request,
provided that no such delay shall be required as to any Underwriter's Securities
if any securities of the Company are included in such registration statement and
eligible for sale during the Delay Period for the account of any person other
than the Company and any Eligible Holder unless the securities included in such
registration statement and eligible for sale during the Delay Period for such
other person shall have been reduced pro rata to the reduction of the
Underwriter's Securities which were requested to be included and eligible for
sale during the Delay Period in such registration. As used herein,
"Underwriter's Securities" shall mean the Option Shares issued upon exercise of
the Underwriter's Options, which have not been previously sold pursuant to a
registration statement or Rule 144 promulgated under the Act.

            (b) If, at any time during the five-year period commencing one year
after the Effective Date, the Company shall receive a written request, from
Eligible Holders who in the aggregate own (or upon exercise of all Options then
outstanding would own) a majority of the total number of shares of Common Stock
then included (or upon such exercises that would be included) in the
Underwriter's Securities (the "Majority Holders"), to register the sale of all
or part of such Underwriter's Securities, the Company shall, as promptly as
practicable, prepare and file with the Commission a registration statement
sufficient to permit the public offering and sale of the Underwriter's
Securities through the facilities of all appropriate securities exchanges and
the over-the-counter market, and will use its best efforts through its officers,
directors, auditors, and counsel to cause such registration statement to become
effective as promptly as practicable; provided, however, that the Company shall
only be obligated to file one such

                                   - 13 -




<PAGE>



registration statement for which all expenses incurred in connection with such
registration (other than the fees and disbursements of counsel for the Eligible
Holders and underwriting discounts, if any, payable in respect of the Under-
writer's Securities sold by the Eligible Holders) shall be borne by the Company
and one additional such registration statement for which all such expenses shall
be paid by the Eligible Holders. Within three business days after receiving any
request contemplated by this Section 9(b), the Company shall give written notice
to all the other Eligible Holders, advising each of them that the Company is
proceeding with such registration and offering to include therein all or any
portion of any such other Eligible Holder's Underwriter's Securities, provided
that the Company receives a written request to do so from such Eligible Holder
within 30 days after receipt by him or it of the Company's notice.

            (c) In the event of a registration pursuant to the provisions of
this Section 9, the Company shall use its best efforts to cause the
Underwriter's Securities so registered to be registered or qualified for sale
under the securities or blue sky laws of such jurisdictions as the Holder or
such holders may reasonably request; provided, however, that the Company shall
not be required to qualify to do business in any state by reason of this Section
9(c) in which it is not otherwise required to qualify to do business.

            (d) The Company shall keep effective any registration or
qualification contemplated by this Section 9 and shall from time to time amend
or supplement each applicable registration statement, preliminary prospectus,
final prospectus, application, document, and communication for such period of
time as shall be required to permit the Eligible Holders to complete the offer
and sale of the Underwriter's Securities covered thereby. The Company shall in
no event be required to keep any such registration or qualification in effect
for a period in excess of nine months from the date on which the Eligible
Holders are first free to sell such Underwriter's Securities; provided, however,
that, if the Company is required to keep any such registration or qualification
in effect with respect to securities other than the Underwriter's Securities
beyond such period, the Company shall keep such registration or qualification in
effect as it relates to the Underwriter's Securities for so long as such
registration or qualification remains or is required to remain in effect in
respect of such other securities.

            (e) In the event of a registration pursuant to the provisions of
this Section 9, the Company shall furnish to each Eligible Holder such number of
copies of the registration statement and of each amendment and supplement
thereto (in each case, including all exhibits), such reasonable number of copies
of each prospectus contained in such registration statement and each supplement
or amendment thereto (including each preliminary prospectus), all of which shall
conform to the requirements of

                                   - 14 -




<PAGE>



the Act and the rules and regulations thereunder, and such other documents, as
any Eligible Holder may reasonably request to facilitate the disposition of the
Underwriter's Securities included in such registration.

            (f) In the event of a registration pursuant to the provisions of
this Section 9, the Company shall furnish each Eligible Holder of any
Underwriter's Securities so registered with an opinion of its counsel
(reasonably acceptable to the Eligible Holders) to the effect that (i) the
registration statement has become effective under the Act and no order
suspending the effectiveness of the registration statement, preventing or
suspending the use of the registration statement, any preliminary prospectus,
any final prospectus, or any amendment or supplement thereto has been issued,
nor has the Commission or any securities or blue sky authority of any
jurisdiction instituted or threatened to institute any proceedings with respect
to such an order, (ii) the registration statement and each prospectus forming a
part thereof (including each preliminary prospectus), and any amendment or
supplement thereto, complies as to form with the Act and the rules and
regulations thereunder, and (iii) such counsel has no knowledge of any material
misstatement or omission in such registration statement or any prospectus, as
amended or supplemented. Such opinion shall also state the jurisdictions in
which the Underwriter's Securities have been registered or qualified for sale
pursuant to the provisions of Section 9(c).

            (g) In the event of a registration pursuant to the provision of this
Section 9, the Company shall enter into a cross-indemnity agreement and a
contribution agreement, each in customary form, with each underwriter, if any,
and, if requested, enter into an underwriting agreement containing conventional
representations, warranties, allocation of expenses, and customary closing
conditions, including, but not limited to, opinions of counsel and accountants'
cold comfort letters, with any underwriter who acquires any Underwriter's
Securities.

            (h) The Company agrees that until all the Underwriter's Securities
have been sold under a registration statement or pursuant to Rule 144 under the
Act, it shall keep current in filing all reports, statements and other materials
required to be filed with the Commission to permit holders of the Underwriter's
Securities to sell such securities under Rule 144.

            (i) Except for rights granted to holders of the Options and rights
existing prior to the issuance of the Options, the Company will not, without the
written consent of the Majority Holders, grant to any persons the right to
request the Company to register any securities of the Company, provided that the
Company may grant such registration rights to other persons so long as such
rights are subordinate to the rights of the Eligible Holders.


                                   - 15 -




<PAGE>



      10. (a) Subject to the conditions set forth below, the Company agrees to
indemnify and hold harmless each Eligible Holder, its officers, directors,
partners, employees, agents, and counsel, and each person, if any, who controls
any such person within the meaning of Section 15 of the Act or Section 20(a) of
the Securities Exchange Act of 1934, as amended (the "Exchange Act"), from and
against any and all loss, liability, charge, claim, damage, and expense
whatsoever (which shall include, for all purposes of this Section 10, but not be
limited to, attorneys' fees and any and all reasonable expense whatsoever
incurred in investigating, preparing, or defending against any litigation,
commenced or threatened, or any claim whatsoever, and any and all amounts paid
in settlement of any claim or litigation), as and when incurred, arising out of,
based upon, or in connection with (i) any untrue statement or alleged untrue
statement of a material fact contained (A) in any registration statement,
preliminary prospectus, or final prospectus (as from time to time amended and
supplemented), or any amendment or supplement thereto, relating to the sale of
any of the Underwriter's Securities or (B) in any application or other document
or communication (in this Section 10 collectively called an "application")
executed by or on behalf of the Company or based upon written information
furnished by or on behalf of the Company filed in any jurisdiction in order to
register or qualify any of the Underwriter's Securities under the securities or
blue sky laws thereof or filed with the Commission or any securities exchange;
or any omission or alleged omission to state a material fact required to be
stated therein or necessary to make the statements therein not misleading,
unless such statement or omission was made in reliance upon and in conformity
with written information furnished to the Company with respect to such Eligible
Holder by or on behalf of such person expressly for inclusion in any
registration statement, preliminary prospectus, or final prospectus, or any
amendment or supplement thereto, or in any application, as the case may be, or
(ii) any breach of any representation, warranty, covenant, or agreement of the
Company contained in this Option. The foregoing agreement to indemnify shall be
in addition to any liability the Company may otherwise have, including
liabilities arising under this Option. The Company shall not be liable for
losses based on untrue statements or omissions contained in Preliminary
Prospectuses if an Underwriter failed to deliver a final Prospectus prior to or
simultaneously with the delivery of written confirmation of any public sale of
the Underwriter's Securities and a court of competent jurisdiction in a judgment
not subject to appeal or final review shall have determined that such final
Prospectus would have corrected such untrue statement or omission.

      If any action is brought against any Eligible Holder or any of its
officers, directors, partners, employees, agents, or counsel, or any controlling
persons of such person (an "indemnified party") in respect of which indemnity
may be sought against the Company pursuant to the foregoing paragraph, such
indemnified party or parties shall promptly notify the Company in

                                   - 16 -




<PAGE>



writing of the institution of such action (but the failure so to notify shall
not relieve the Company from any liability other than pursuant to this Section
10(a)) and the Company shall promptly assume the defense of such action,
including the employment of counsel (reasonably satisfactory to such indemnified
party or parties) and payment of expenses. Such indemnified party or parties
shall have the right to employ its or their own counsel in any such case, but
the fees and expenses of such counsel shall be at the expense of such
indemnified party or parties unless the employment of such counsel shall have
been authorized in writing by the Company in connection with the defense of such
action or the Company shall not have promptly employed counsel reasonably
satisfactory to such indemnified party or parties to have charge of the defense
of such action or such indemnified party or parties shall have reasonably
concluded that there may be one or more legal defenses available to it or them
or to other indemnified parties which are different from or additional to those
available to the Company, in any of which events such fees and expenses shall be
borne by the Company and the Company shall not have the right to direct the
defense of such action on behalf of the indemnified party or parties. Anything
in this Section 10 to the contrary notwithstanding, the Company shall not be
liable for any settlement of any such claim or action effected without its
written consent, which shall not be unreasonably withheld. The Company shall
not, without the prior written consent of each indemnified party that is not
released as described in this sentence, settle or compromise any action, or
permit a default or consent to the entry of judgment in or otherwise seek to
terminate any pending or threatened action, in respect of which indemnity may be
sought hereunder (whether or not any indemnified party is a party thereto),
unless such settlement, compromise, consent, or termination includes an
unconditional release of each indemnified party from all liability in respect of
such action. The Company agrees promptly to notify the Eligible Holders of the
commencement of any litigation or proceedings against the Company or any of its
officers or directors in connection with the sale of any Underwriter's
Securities or any preliminary prospectus, prospectus, registration statement, or
amendment or supplement thereto, or any application relating to any sale of any
Underwriter's Securities.

            (b) The Holder agrees to indemnify and hold harmless the Company,
each director of the Company, each officer of the Company who shall have signed
any registration statement covering Underwriter's Securities held by the Holder,
each other person, if any, who controls the Company within the meaning of
Section 15 of the Act or Section 20(a) of the Exchange Act, and its or their
respective counsel, to the same extent as the foregoing indemnity from the
Company to the Holder in Section 10(a), but only with respect to statements or
omissions, if any, made in any registration statement, preliminary prospectus,
or final prospectus (as from time to time amended and supplemented), or any
amendment or supplement thereto, or in any application, in

                                   - 17 -




<PAGE>



reliance upon and in conformity with written information furnished to the
Company with respect to the Holder by or on behalf of the Holder expressly for
inclusion in any such registration statement, preliminary prospectus, or final
prospectus, or any amendment or supplement thereto, or in any application, as
the case may be. If any action shall be brought against the Company or any other
person so indemnified based on any such registration statement, preliminary
prospectus, or final prospectus, or any amendment or supplement thereto, or in
any application, and in respect of which indemnity may be sought against the
Holder pursuant to this Section 10(b), the Holder shall have the rights and
duties given to the Company, and the Company and each other person so
indemnified shall have the rights and duties given to the indemnified parties,
by the provisions of Section 10(a).

            (c) To provide for just and equitable contribution, if (i) an
indemnified party makes a claim for indemnification pursuant to Section 10(a) or
10(b) (subject to the limitations thereof) but it is found in a final judicial
determination, not subject to further appeal, that such indemnification may not
be enforced in such case, even though this Agreement expressly provides for
indemnification in such case, or (ii) any indemnified or indemnifying party
seeks contribution under the Act, the Exchange Act or otherwise, then the
Company (including for this purpose any contribution made by or on behalf of any
director of the Company, any officer of the Company who signed any such
registration statement, any controlling person of the Company, and its or their
respective counsel), as one entity, and the Eligible Holders of the
Underwriter's Securities included in such registration in the aggregate
(including for this purpose any contribution by or on behalf of an indemnified
party), as a second entity, shall contribute to the losses, liabilities, claims,
damages, and expenses whatsoever to which any of them may be subject, on the
basis of relevant equitable considerations such as the relative fault of the
Company and such Eligible Holders in connection with the facts which resulted in
such losses, liabilities, claims, damages, and expenses. The relative fault, in
the case of an untrue statement, alleged untrue statement, omission, or alleged
omission, shall be determined by, among other things, whether such statement,
alleged statement, omission, or alleged omission relates to information supplied
by the Company or by such Eligible Holders, and the parties' relative intent,
knowledge, access to information, and opportunity to correct or prevent such
statement, alleged statement, omission, or alleged omission. The Company and the
Holder agree that it would be unjust and inequitable if the respective
obligations of the Company and the Eligible Holders for contribution were
determined by pro rata or per capita allocation of the aggregate losses,
liabilities, claims, damages, and expenses (even if the Holder and the other

method of allocation that does not reflect the equitable considerations referred
to in this Section 10(c). In no case

                                   - 18 -

shall any Eligible Holder be responsible for a portion of the contribution
obligation imposed on all Eligible Holders in excess of its pro rata share based
on the number of shares of Common Stock owned (or which would be owned upon
exercise of all Underwriter's Securities) by it and included in such
registration as compared to the number of shares of Common Stock owned (or which
would be owned upon exercise of all Underwriter's Securities) by all Eligible
Holders and included in such registration. No person guilty of a fraudulent
misrepresentation (within the meaning of Section 11(f) of the Act) shall be
entitled to contribution from any person who is not guilty of such fraudulent
misrepresentation. For purposes of this Section 10(c), each person, if any, who
controls any Eligible Holder within the meaning of Section 15 of the Act or
Section 20(a) of the Exchange Act and each officer, director, partner, employee,
agent, and counsel of each such Eligible Holder or control person shall have the
same rights to contribution as such Eligible Holder or control person and each
person, if any, who controls the Company within the meaning of Section 15 of the
Act or Section 20(a) of the Exchange Act, each officer of the Company who shall
have signed any such registration statement, each director of the Company, and
its or their respective counsel shall have the same rights to contribution as
the Company, subject in each case to the provisions of this Section 10(c).
Anything in this Section 10(c) to the contrary notwithstanding, no party shall
be liable for contribution with respect to the settlement of any claim or action
effected without its written consent. This Section 10(c) is intended to
supersede any right to contribution under the Act, the Exchange Act or
otherwise.

      11. Unless registered pursuant to the provisions of Section 9 hereof, the
Option Shares issued upon exercise of the Options shall be subject to a stop
transfer order and the certificate or certificates evidencing such securities
shall bear the following legend:

                  "THE SHARES REPRESENTED BY THIS CERTIFICATE HAVE BEEN
            REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED, PURSUANT TO
            A REGISTRATION STATEMENT FILED WITH THE SECURITIES AND EXCHANGE
            COMMISSION. HOWEVER, SUCH SHARES MAY NOT BE OFFERED OR SOLD EXCEPT
            PURSUANT TO (i) A POST-EFFECTIVE AMENDMENT TO SUCH REGISTRATION
            STATEMENT, (ii) A SEPARATE REGISTRATION STATEMENT UNDER SUCH ACT, OR
            (iii) AN EXEMPTION FROM REGISTRATION UNDER SUCH ACT."

      12. Upon receipt of evidence satisfactory to the Company of the loss,
theft, destruction, or mutilation of any Option (and upon surrender of any
Option if mutilated), and upon reimbursement of the Company's reasonable
incidental expenses, the Company shall execute and deliver to the Holder thereof
a new Option of like date, tenor, and denomination.

                                   - 19 -

      13. The Holder of any Option shall not have, solely on account of such
status, any rights of a stockholder of the Company, either at law or in equity,
or to any notice of meetings of stockholders or of any other proceedings of the
Company, except as provided in this Option.

      14. This Option shall be construed in accordance with the laws of the
State of New York applicable to contracts made and performed within such State,
without regard to principles of conflicts of law.

      15. The Company irrevocably consents to the jurisdiction of the courts of
the State of New York and of any federal court located in such State in
connection with any action or proceeding arising out of or relating to this
Option, any document or instrument delivered pursuant to, in connection with or
simultaneously with this Option, or a breach of this Option or any such document
or instrument. In any such action or proceeding, the Company waives personal
service of any summons, complaint or other process and agrees that service
thereof may be made in accordance with Section 12 of the Underwriting Agreement.

      Within 30 days after such service, or such other time as may be mutually
agreed upon in writing by the attorneys for the parties to such action or
proceeding, the Company shall appear to answer such summons, complaint or other
process.

                              THINKING TOOLS, INC.

                             1996 STOCK OPTION PLAN

                             Adopted August 9, 1996

     SECTION 1. PURPOSE. The purpose of the Thinking Tools, Inc. 1996 Stock
Option Plan (the "Plan"), is to provide a means whereby selected employees,
officers, directors, agents, consultants, and independent contractors of
Thinking Tools, Inc., a Delaware corporation (the "Company"), or of any parent
or subsidiary (as defined in subsection 5.7 hereof and referred to hereinafter
as "Affiliates") thereof, may be granted incentive stock options and/or
nonqualified stock options to purchase shares of common stock, $.001 par value
("Common Stock"), in order to attract and retain the services or advice of such
directors, employees, officers, agents, consultants, and independent contractors
and to provide additional incentive for such persons to exert maximum efforts
for the success of the Company and its Affiliates by encouraging stock ownership
in the Company.

     SECTION 2. ADMINISTRATION. Subject to Section 2.3 hereof, the Plan shall be
administered by the Board of Directors of the Company (the "Board") or, in the
event the Board shall appoint and/or authorize a committee of two or more
members of the Board to administer the Plan, by such committee. The
administrator of the Plan shall hereinafter be referred to as the "Plan
Administrator."

     The foregoing notwithstanding, in the event the Company shall register any
of its equity securities pursuant to Section 12(b) or 12(g) of the Securities
Exchange Act of 1934, as amended (the "Exchange Act"), and any directors are
eligible to receive options under the Plan, then with respect to grants to be
made to directors: (a) the Plan Administrator shall be constituted so as to meet
the requirements of Section 16(b) of the Exchange Act and Rule 16b-3 thereunder,
each as amended from time to time, or (b) if the Plan Administrator cannot be so
constituted, no options shall be granted under the Plan to any directors.

     2.1 PROCEDURES. The Board shall designate one of the members of the Plan
Administrator as chairman. The Plan Administrator may hold meetings at such
times and places as it shall determine. The acts of a majority of the members of
the Plan Administrator present at meetings at which a quorum exists, or acts
approved in writing by all Plan Administrator members, shall be valid acts of
the Plan Administrator.

     2.2 RESPONSIBILITIES. Except for the terms and conditions explicitly set
forth herein, the Plan Administrator shall have the authority, in its
discretion, to determine all matters relating to the options to be granted under
the Plan, including, without limitation, selection of whether an option will be
an incentive stock option or a nonqualified stock option, selection of the
individuals to be granted options, the number of shares to be subject to each
option, the exercise price per share, the timing of grants and all other terms
and conditions of the options. Grants under the Plan need not be identical in
any respect, even when made simultaneously. The Plan Administrator may also
establish, amend, and revoke rules and


<PAGE>




regulations for the administration of the Plan. The interpretation and
construction by the Plan Administrator of any terms or provisions of the Plan or
any option issued hereunder, or of any rule or regulation promulgated in
connection herewith, shall be conclusive and binding on all interested parties,
so long as such interpretation and construction with respect to incentive stock
options corresponds to the requirements of Internal Revenue Code of 1986, as
amended (the "Code") Section 422, the regulations thereunder, and any amendments
thereto. The Plan Administrator shall not be personally liable for any action
made in good faith with respect to the Plan or any option granted thereunder.

     2.3 RULE 16B-3 AND SECTION 16(B) COMPLIANCE; BIFURCATION OF PLAN. It is the
intention of the Company that the Plan comply in all respects with Rule 16b-3
under the Exchange Act, to the extent applicable, and in all events the Plan
shall be construed in favor of its meeting the requirements of Rule 16b-3. If
any Plan provision is later found not to be in compliance with such Rule, such
provision shall be deemed null and void. The Board of Directors may act under
the Plan only if all members thereof are "disinterested persons" as defined in
Rule 16b-3 and further described in Section 4 hereof; and from and after the
date that the Company first registers a class of equity securities under Section
12 of the Exchange Act, no director or officer or other Company "insider"
subject to Section 16 of the Exchange Act may sell shares received upon the
exercise of an option during the six month period immediately following the
grant of the option. Notwithstanding anything in the Plan to the contrary, the
Board, in its absolute discretion, may bifurcate the Plan so as to restrict,
limit, or condition the use of any provision of the Plan to participants who are
officers and directors or other persons subject to Section 16(b) of the Exchange
Act without so restricting, limiting, or conditioning the Plan with respect to
other participants.

     SECTION 3. STOCK SUBJECT TO THE PLAN. The stock subject to this Plan shall
be the Common Stock, presently authorized but unissued or subsequently acquired
by the Company. Subject to adjustment as provided in Section 7 hereof, the
aggregate amount of Common Stock to be delivered upon the exercise of all
options granted under the Plan shall not exceed in the aggregate 376,000 shares
as such Common Stock was constituted on the effective date of the Plan. If any
option granted under the Plan shall expire, be surrendered, exchanged for
another option, cancelled, or terminated for any reason without having been
exercised in full, the unpurchased shares subject thereto shall thereupon again
be available for purposes of the Plan, including for replacement options which
may be granted in exchange for such surrendered, cancelled, or terminated
options.

     SECTION 4. ELIGIBILITY. An incentive stock option may be granted only to
any individual who, at the time the option is granted, is an employee of the
Company or any Affiliate thereof. A nonqualified stock option may be granted to
any director, employee, officer, agent, consultant, or independent contractor of
the Company or any Affiliate thereof, whether an individual or an entity. Any
party to whom an option is granted under the Plan shall be referred to
hereinafter as an "Optionee".

     A director shall in no event be eligible for the benefits of the Plan
unless at the time discretion is exercised in the selection of a director as a
person to whom options may be

                                      - 2 -

<PAGE>



granted, or in the determination of the number of shares which may be covered by
options granted to the director, the Plan complies with the requirements of Rule
16b-3 under the Exchange Act.

     SECTION 5. TERMS AND CONDITIONS OF OPTIONS. Options granted under the Plan
shall be evidenced by written agreements which shall contain such terms,
conditions, limitations, and restrictions as the Plan Administrator shall deem
advisable and which are not inconsistent with the Plan. Notwithstanding the
foregoing, options shall include or incorporate by reference the following terms
and conditions:

     5.1 NUMBER OF SHARES AND PRICE. The maximum number of shares that may be
purchased pursuant to the exercise of each option, and the price per share at
which such option is exercisable (the "exercise price"), shall be as established
by the Plan Administrator; provided, that the Plan Administrator shall act in
good faith to establish the exercise price which shall be not less than 100% of
the fair market value per share of the Common Stock at the time of grant of the
option; and provided, further, that, with respect to incentive stock options
granted to greater than ten percent stockholders, the exercise price shall be as
required by Section 6 hereof.

     5.2 TERM AND MATURITY. Subject to the restrictions contained in Section 6
hereof with respect to granting stock options to greater than ten percent
stockholders, the term of each stock option shall be as established by the Plan
Administrator and, if not so established, shall be ten years from the date of
its grant, but in no event shall the term of any incentive stock option exceed a
ten year period. The vesting period and time for exercising an option shall be
prescribed by the Plan Administrator in each particular case.

     5.3 EXERCISE. Subject to any vesting schedule established by the Plan
Administrator pursuant to Subsection 5.2 hereof, each option may be exercised in
whole or in part; provided, that only whole shares may be issued pursuant to the
exercise of any option. Subject to any other terms and conditions herein, the
Plan Administrator may provide that an option may not be exercised in whole or
in part for a stated period or periods of time during which such option is
outstanding; provided, that the Plan Administrator may rescind, modify, or waive
any such limitation at any time and from time to time after the grant date
thereof. During an Optionee's lifetime, any incentive stock options granted
under the Plan are personal to such Optionee and are exercisable solely by such
Optionee. Options shall be exercised by delivery to the Company of notice of the
number of shares with respect to which the option is exercised, together with
payment of the exercise price in accordance with Section 5.4 hereof.

     5.4 PAYMENT OF EXERCISE PRICE. Payment of the option exercise price shall
be made in full at the time the notice of exercise of the option is delivered to
the Company and shall be in cash, bank certified or cashier's check, or personal
check (unless at the time of exercise the Plan Administrator in a particular
case determines not to accept a personal check) for shares of Common Stock being
purchased.

  The Plan Administrator can determine at the time the option is granted in the

                                      - 3 -

<PAGE>


case of incentive stock options, or at any time before exercise in the case of
nonqualified stock options, that additional forms of payment will be permitted.

     To the extent permitted by the Plan Administrator and applicable laws and
regulations (including, without limitation, federal tax and securities laws and
regulations and state corporate law), an option may be exercised by delivery of
a properly executed Notice of Exercise, together with irrevocable instructions
to a broker, all in accordance with the regulations of the Federal Reserve
Board, to promptly deliver to the Company the amount of sale or loan proceeds to
pay the exercise price and any federal, state, or local withholding tax
obligations that may arise in connection with the exercise; provided, that the
Plan Administrator, in its sole discretion, may at any time determine that this
sentence, to the extent the instructions to the broker call for an immediate
sale of the shares, shall not be applicable to any Optionee who is subject to
Section 16(b) of the Exchange Act, or is not an employee at the time of
exercise.

     5.5 WITHHOLDING TAX REQUIREMENT. The Company or any Affiliate thereof shall
have the right to retain and withhold from any payment of cash or Common Stock
under the Plan the amount of taxes required by any government to be withheld or
otherwise deducted and paid with respect to such payment. No option may be
exercised unless and until arrangements satisfactory to the Company, in its sole
discretion, to pay such withholding taxes are made. At its discretion, the
Company may require an Optionee to reimburse the Company for any such taxes
required to be withheld by the Company and withhold any distribution in whole or
in part until the Company is so reimbursed. In lieu thereof, the Company shall
have the right to withhold from any other cash amounts due or to become due from
the Company to the Optionee an amount equal to such taxes or retain and withhold
a number of shares having a market value not less than the amount of such taxes
required to be withheld by the Company to reimburse the Company for any such
taxes and cancel (in whole or in part) any such shares of Common Stock so
withheld. If required by Section 16(b) of the Exchange Act, the election to pay
withholding taxes by delivery of shares of Common Stock held by any person who
at the time of exercise is subject to Section 16(b) of the Exchange Act shall be
made either six months prior to the date the option exercise becomes taxable or
at such other times as the Company may determine as necessary to comply with
Section 16(b) of the Exchange Act. Although the Company may, in its discretion,
accept Common Stock as payment of withholding taxes, the Company shall not be
obligated to do so.

                  5.6      NONTRANSFERABILITY.

     5.6.1 OPTION. Options granted under the Plan and the rights and privileges
conferred hereby may not be transferred, assigned, pledged, or hypothecated in
any manner (whether by operation of law or otherwise) other than by will or by
the applicable laws of descent and distribution or pursuant to a qualified
domestic relations order as defined in Section 414(p) of the Code, or Title I of
the Employee Retirement Income Security Act of 1974, as amended, or the rules
thereunder, and shall not be subject to execution, attachment, or similar
process. Any attempt to transfer, assign, pledge, hypothecate, or otherwise
dispose of any option under the Plan or of any right or privilege conferred
hereby, contrary to the Code

                                      - 4 -

<PAGE>


or to the provisions of the Plan, or the sale or levy or any attachment or
similar process upon the rights and privileges conferred hereby shall be null
and void ab initio. The designation by an Optionee of a beneficiary does not, in
and of itself, constitute an impermissible transfer under this subsection 5.6.1.

     5.6.2 STOCK. The Plan Administrator may provide in the agreement granting
the option that (a) the Optionee may not transfer or otherwise dispose of shares
acquired upon exercise of an option without first offering such shares to the
Company for purchase on the same terms and conditions as those offered to the
proposed transferee or (b) upon termination of employment of an Optionee the
Company shall have a six month right of repurchase as to the shares acquired
upon exercise, which right of repurchase shall allow for a maximum purchase
price equal to the fair market value of the shares on the termination date. The
foregoing rights of the Company shall be assignable by the Company upon
reasonable written notice to the Optionee.

     5.7 TERMINATION OF RELATIONSHIP. If the Optionee's relationship with the
Company or any Affiliate thereof ceases for any reason other than termination
for cause, death, or total disability, and unless by its terms the option sooner
terminates or expires, then the Optionee may exercise, for a three month period,
that portion of the Optionee's option which is exercisable at the time of such
cessation, but the Optionee's option shall terminate at the end of the three
month period following such cessation as to all shares for which it has not
theretofore been exercised, unless, in the case of a nonqualified stock option,
such provision is waived in the agreement evidencing the option or by resolution
adopted by the Plan Administrator within 90 days of such cessation. If, in the
case of an incentive stock option, an Optionee's relationship with the Company
or Affiliate thereof changes from employee to nonemployee (i.e., from employee
to a position such as a consultant), such change shall constitute a termination
of an Optionee's employment with the Company or Affiliate and the Optionee's
incentive stock option shall terminate in accordance with this subsection 5.7.

     If an Optionee is terminated for cause, any option granted hereunder shall
automatically terminate as of the first discovery by the Company of any reason
for termination for cause, and such Optionee shall thereupon have no right to
purchase any shares pursuant to such option. "Termination for cause" shall mean
dismissal for dishonesty, conviction or confession of a crime punishable by law
(except minor violations), fraud, misconduct, or disclosure of confidential
information. If an Optionee's relationship with the Company or any Affiliate
thereof is suspended pending an investigation of whether or not the Optionee
shall be terminated for cause, all Optionee's rights under any option granted
hereunder likewise shall be suspended during the period of investigation.

     If an Optionee's relationship with the Company or any Affiliate thereof
ceases because of a total disability, the Optionee's option shall not terminate
or, in the case of an incentive stock option, cease to be treated as an
incentive stock option until the end of the 12 month period following such
cessation (unless by its terms it sooner terminates and expires). As used in the
Plan, the term "total disability" refers to a mental or physical impairment of
the Optionee which is expected to result in death or which has lasted or is, in
the opinion of the

                                      - 5 -

<PAGE>


Company and two independent physicians, expected to last for a continuous period
of 12 months or more and which causes or is, in such opinion, expected to cause
the Optionee to be unable to perform his or her duties for the Company and to be
engaged in any substantial gainful activity. Total disability shall be deemed to
have occurred on the first day after the Company and the two independent
physicians have furnished their opinion of total disability to the Plan
Administrator.

     For purposes of this subsection 5.7, a transfer of relationship between or
among the Company and/or any Affiliate thereof shall not be deemed to constitute
a cessation of relationship with the Company or any of its Affiliates. For
purposes of this subsection 5.7, with respect to incentive stock options,
employment shall be deemed to continue while the Optionee is on military leave,
sick leave, or other bona fide leave of absence (as determined by the Plan
Administrator). The foregoing notwithstanding, employment shall not be deemed to
continue beyond the first 90 days of such leave, unless the Optionee's
reemployment rights are guaranteed by statute or by contract.

     As used herein, the term "Affiliate" shall be defined as follows: (a) when
referring to a subsidiary corporation, "Affiliate" shall mean any corporation
(other than the Company) in, at the time of the granting of the option, an
unbroken chain of corporations ending with the Company, if stock possessing 50%
or more of the total combined voting power of all classes of stock of each of
the corporations other than the Company is owned by one of the other
corporations in such chain; and (b) when referring to a parent corporation,
"Affiliate" shall mean any corporation in an unbroken chain of corporations
ending with the Company if, at the time of the granting of the option, each of
the corporations other than the Company owns stock possessing 50% or more of the
total combined voting power of all classes of stock in one of the other
corporations in such chain.

     5.8 DEATH OF OPTIONEE. If an Optionee dies while he or she has a
relationship with the Company or any Affiliate thereof or within the three month
period (or 12 month period in the case of totally disabled Optionees) following
cessation of such relationship, any option held by such Optionee, to the extent
that the Optionee would have been entitled to exercise such option, may be
exercised within one year after his or her death by the personal representative
of his or her estate or by the person or persons to whom the Optionee's rights
under the option shall pass by will or by the applicable laws of descent and
distribution.

     5.9 STATUS OF STOCKHOLDER. Neither the Optionee nor any party to which the
Optionee's rights and privileges under the option may pass shall be, or have any
of the rights or privileges of, a stockholder of the Company with respect to any
of the shares issuable upon the exercise of any option granted under the Plan
unless and until such option has been exercised.

     5.10 CONTINUATION OF EMPLOYMENT. Nothing in the Plan or in any option
granted pursuant to the Plan shall confer upon any Optionee any right to
continue in the employ of the Company or of an Affiliate thereof, or to
interfere in any way with the right of the Company or of any such Affiliate to
terminate his or her employment or other relationship with

                                      - 6 -

<PAGE>


the Company at any time.

     5.11 MODIFICATION AND AMENDMENT OF OPTION. Subject to the requirements of
Section 422 of the Code with respect to incentive stock options and to the terms
and conditions and within the limitations of the Plan, including, without
limitation, Section 9.1 hereof, the Plan Administrator may modify or amend
outstanding options granted under the Plan. The modification or amendment of an
outstanding option shall not, without the consent of the Optionee, impair or
diminish any of his or her rights or any of the obligations of the Company under
such option. Except as otherwise provided herein, no outstanding option shall be
terminated without the consent of the Optionee. Unless the Optionee agrees
otherwise, any changes or adjustments made to outstanding incentive stock
options granted under the Plan shall be made in such a manner so as not to
constitute a "modification" as defined in Section 424(h) of the Code and so as
not to cause any incentive stock option issued hereunder to fail to continue to
qualify as an incentive stock option as defined in Section 422(b) of the Code.

     5.12 LIMITATION ON VALUE FOR INCENTIVE STOCK OPTIONS. As to all incentive
stock options granted under the terms of the Plan, to the extent that the
aggregate fair market value (determined at the time of the grant of the
incentive stock option) of the shares of Common Stock with respect to which
incentive stock options are exercisable for the first time by the Optionee
during any calendar year (under the Plan and all other incentive stock option
plans of the Company, an Affiliate thereof or a predecessor corporation) exceeds
$100,000, such options shall be treated as nonqualified stock options. The
foregoing sentence shall not apply, and the limitation shall be that provided by
the Code or the Internal Revenue Service, as the case may be, if such annual
limit is changed or eliminated by (a) amendment of the Code or (b) issuance by
the Internal Revenue Service of (i) a Revenue ruling, (ii) a Private Letter
ruling to any of the Company, any Optionee, or any legatee, personal
representative, or distributee of any Optionee, or (iii) regulations.

     5.13 VALUATION OF COMMON STOCK RECEIVED UPON EXERCISE. The value of Common
Stock received by the Optionee from an exercise under the third paragraph of
Section 5.4 hereof shall equal the sales price received for such shares.

         SECTION 6. GREATER THAN TEN PERCENT STOCKHOLDERS.

     6.1 EXERCISE PRICE AND TERM OF INCENTIVE STOCK OPTIONS. If incentive stock
options are granted under the Plan to employees who, at the time of such grant,
own greater than ten percent of the total combined voting power of all classes
of stock of the Company or any Affiliate thereof, the term of such incentive
stock options shall not exceed five years and the exercise price shall be not
less than 110% of the fair market value of the Common Stock at the time of grant
of the incentive stock option. This provision shall control notwithstanding any
contrary terms contained in an option agreement or any other document. The term
and exercise price limitations of this provision shall be amended to conform to
any change required by a change in the Code or by ruling or pronouncement of the
Internal Revenue Service.

     6.2 ATTRIBUTION RULE. For purposes of subsection 6.1, in determining stock

                                      - 7 -

ownership, an employee shall be deemed to own the stock owned, directly or
indirectly, by or for his or her brothers, sisters, spouse, ancestors, and
lineal descendants. Stock owned, directly or indirectly, by or for a
corporation, partnership estate, or trust shall be deemed to be owned
proportionately by or for its stockholders, partners, or beneficiaries. If an
employee or a person related to the employee owns an unexercised option or
warrant to purchase stock of the Company, the stock subject to that portion of
the option or warrant which is unexercised shall not be counted in determining
stock ownership. For purposes of this Section 6, stock owned by an employee
shall include all stock owned by him or her which is actually issued and
outstanding immediately before the grant of the incentive stock option to the
employee.

     SECTION 7. ADJUSTMENTS UPON CHANGES IN CAPITALIZATION. The aggregate number
and class of shares for which options may be granted under the Plan, the number
and class of shares covered by each outstanding option, and the exercise price
per share thereof (but not the total price), and each such option, shall all be
proportionately adjusted for any increase or decrease in the number of issued
shares of Common Stock of the Company resulting from a split or consolidation of
shares or any like capital adjustment, or the payment of any stock dividend.

     7.1. EFFECT OF LIQUIDATION, REORGANIZATION, OR CHANGE IN CONTROL.

     7.1.1 CASH, STOCK, OR OTHER PROPERTY FOR STOCK. Except as provided in
subsection 7.1.2 hereof, upon a merger (other than a merger of the Company in
which the holders of Common Stock immediately prior to the merger have the same
proportionate ownership of common stock in the surviving corporation immediately
after the merger), consolidation, acquisition of property or stock, separation,
reorganization (other than mere reincorporation or creation of a holding
company), or liquidation of the Company (each, an "event"), as a result of which
the stockholders of the Company receive cash, stock, or other property in
exchange for, or in connection with, their shares of Common Stock, any option
granted hereunder shall terminate, but the time during which such options may be
exercised shall be accelerated as follows: the Optionee shall have the right
immediately prior to any such event to exercise such Optionee's option in whole
or in part whether or not the vesting requirements set forth in the option
agreement have been satisfied.

     7.1.2 CONVERSION OF OPTIONS ON STOCK FOR EXCHANGE STOCK. If the
stockholders of the Company receive capital stock of another corporation
("Exchange Stock") in exchange for their shares of Common Stock in any
transaction involving a merger (other than a merger of the Company in which the
holders of Common Stock immediately prior to the merger have the same
proportionate ownership of common stock in the surviving corporation immediately
after the merger), consolidation, acquisition of property or stock, separation,
or reorganization (other than mere reincorporation or creation of a holding
company), all options granted hereunder shall be converted into options to
purchase shares of Exchange Stock unless the Company and corporation issuing the
Exchange Stock, in their sole discretion, determine that any or all such options
granted hereunder shall not be converted into options to purchase shares of
Exchange Stock but instead shall terminate in accordance with the provisions of
subsection 7.1.1 hereof. The amount and price of converted options shall be
determined by

                                      - 8 -

<PAGE>



adjusting the amount and price of the options granted hereunder in the same
proportion as used for determining the number of shares of Exchange Stock the
holders of the Common Stock receive in such merger, consolidation, acquisition,
separation, or reorganization. Unless the Board determines otherwise, the
converted options shall be fully vested whether or not the vesting requirements
set forth in the option agreement have been satisfied.

     7.2 FRACTIONAL SHARES. In the event of any adjustment in the number of
shares covered by an option, any fractional shares resulting from such
adjustment shall be disregarded and each such option shall cover only the number
of full shares resulting from such adjustment.

     7.3 DETERMINATION OF BOARD TO BE FINAL. Except as otherwise required for
the Plan to qualify for the exemption afforded by Rule 16b-3 under the Exchange
Act, all adjustments under this Section 7 shall be made by the Board, and its
determination as to what adjustments shall be made, and the extent thereof,
shall be final, binding, and conclusive. Unless an Optionee agrees otherwise,
any change or adjustment to an incentive stock option shall be made in such a
manner so as not to constitute a "modification" as defined in Section 425(h) of
the Code and so as not to cause the incentive stock option issued hereunder to
fail to continue to qualify as an incentive stock option as defined in Section
422(b) of the Code.

     SECTION 8. SECURITIES LAW COMPLIANCE. Shares shall not be issued with
respect to an option granted under the Plan unless the exercise of such option
and the issuance and delivery of such shares pursuant thereto shall comply with
all relevant provisions of law, including, without limitation, any applicable
state securities laws, the Securities Act of 1933, as amended (the "Act"), 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, including, without limitation, the availability of an
exemption from registration for the issuance and sale of any shares hereunder.
Inability of the Company to obtain from any regulatory body having jurisdiction,
the authority deemed by the Company's counsel to be necessary for the lawful
issuance and sale of any shares hereunder or the unavailability of an exemption
from registration for the issuance and sale of any shares hereunder shall
relieve the Company of any liability in respect of the nonissuance or sale of
such shares as to which such requisite authority shall not have been obtained.

     As a condition to the exercise of an option, if, in the opinion of counsel
for the Company, assurances are required by any relevant provision of the
aforementioned laws, the Company may require the Optionee to give written
assurances satisfactory to the Company at the time of any such exercise (a) as
to the Optionee's knowledge and experience in financial and business matters
(and/or to employ a purchaser representative reasonably satisfactory to the
Company who is knowledgeable and experienced in financial and business matters)
and that such Optionee is capable of evaluating, either alone or with the
purchaser representative, the merits and risks of exercising the option or (b)
that the shares are being purchased only for investment and without any present
intention to sell or distribute such shares. The foregoing requirements shall be
inoperative if the issuance of the shares upon the exercise of the option

                                      - 9 -

<PAGE>


has been registered under a then currently effective registration statement
under the Act.

     At the option of the Company, a stop-transfer order against any shares may
be placed on the official stock books and records of the Company, and a legend
indicating that the stock may not be pledged, sold, or otherwise transferred
unless an opinion of counsel is provided (concurred in by counsel for the
Company) stating that such transfer is not in violation of any applicable law or
regulation, may be stamped on stock certificates in order to assure exemption
from registration. The Plan Administrator may also require such other action or
agreement by the Optionees as may from time to time be necessary to comply with
the federal and state securities laws. NONE OF THE ABOVE SHALL BE CONSTRUED TO
IMPLY AN OBLIGATION ON THE PART OF THE COMPANY TO UNDERTAKE REGISTRATION OF THE
OPTIONS OR STOCK HEREUNDER.

     Should any of the Company's capital stock of the same class as the stock
subject to options granted hereunder be listed on a national securities exchange
or on the NASDAQ National Market, all stock issued hereunder if not previously
listed on such exchange or market shall, if required by the rules of such
exchange or market, be authorized by that exchange or market for listing thereon
prior to the issuance thereof.

     SECTION 9. USE OF PROCEEDS. The proceeds received by the Company from the
sale of shares pursuant to the exercise of options granted hereunder shall
constitute general funds of the Company.

         SECTION 10. AMENDMENT AND TERMINATION.

     10.1 BOARD ACTION. The Board may at any time suspend, amend, or terminate
the Plan, provided, that no amendment shall be made without stockholder approval
within 12 months before or after adoption of the Plan if such approval is
necessary to comply with any applicable tax or regulatory requirement, including
any such approval as may be necessary to satisfy the requirements for exemptive
relief under Rule 16b-3 of the Exchange Act or any successor provision. Rights
and obligations under any option granted before amendment of the Plan shall not
be altered or impaired by any amendment of the Plan unless the Company requests
the consent of the person to whom the option was granted and such person
consents in writing thereto.

     10.2 AUTOMATIC TERMINATION. Unless sooner terminated by the Board, the Plan
shall terminate ten years from the earlier of (a) the date on which the Plan is
adopted by the Board or (b) the date on which the Plan is approved by the
stockholders of the Company. No option may be granted after such termination or
during any suspension of the Plan. The amendment or termination of the Plan
shall not, without the consent of the option holder, alter or impair any rights
or obligations under any option theretofore granted under the Plan.

     SECTION 11. EFFECTIVENESS OF THE PLAN. The Plan shall become effective upon
adoption by the Board so long as it is approved by the holders of a majority of
the Company's outstanding shares of voting capital stock at any time within 12
months before or after the adoption of the Plan by the Board.

THE WARRANT REPRESENTED BY THIS CERTIFICATE AND THE SHARES ISSUABLE UPON
EXERCISE HEREOF HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS
AMENDED (THE "ACT"), OR ANY STATE SECURITIES LAWS AND NEITHER SUCH SECURITIES
NOR ANY INTEREST THEREIN MAY BE OFFERED, SOLD, PLEDGED, ASSIGNED OR OTHERWISE
TRANSFERRED UNLESS (1) A REGISTRATION STATEMENT WITH RESPECT THERETO IS
EFFECTIVE UNDER THE ACT AND ANY APPLICABLE STATE SECURITIES LAWS, OR (2) THE
COMPANY RECEIVES AN OPINION OF COUNSEL TO THE HOLDER OF SUCH SECURITIES, WHICH
COUNSEL AND OPINION ARE REASONABLY SATISFACTORY TO THE COMPANY, THAT SUCH
SECURITIES MAY BE OFFERED, SOLD, PLEDGED, ASSIGNED OR TRANSFERRED IN THE MANNER
CONTEMPLATED WITHOUT AN EFFECTIVE REGISTRATION STATEMENT UNDER THE ACT OR
APPLICABLE STATE SECURITIES LAWS. THE WARRANT REPRESENTED BY THIS CERTIFICATE
MAY ALSO BE SUBJECT TO A LOCK-UP AGREEMENT BETWEEN THE ORIGINAL HOLDER AND
BARINGTON CAPITAL GROUP, L.P.

                         THE TRANSFER OF THIS WARRANT IS
                         RESTRICTED AS DESCRIBED HEREIN.

                              THINKING TOOLS, INC.

             Warrant for the Purchase of Shares of Common Stock,
                          $.001 par value per share


                   THIS WARRANT EXPIRES ON ________ , 2001


No. _                                                        _____,000 Shares

            THIS CERTIFIES that, for value received, _____________ with an
address at ________________________________________ (including any transferee,
the "Holder"), is entitled to subscribe for and purchase from Thinking Tools,
Inc., a Delaware corporation (the "Company"), upon the terms and conditions set
forth herein, at any time or from time to time before 5:00 P.M. on ______, 2001,
New York time (the "Exercise Period"), _____,000 shares of the Company's Common
Stock, $.001 par value per share ("Common Stock"), at a price equal to $4.20 per
share prior to consummation of the Company's initial public offering, and at the
lesser of $4.20 and 60% of the initial public offering price per share of Common
Stock in the Company's initial public offering thereafter (the "Exercise
Price").

            If the Company avails itself of the Initial Extension Period or the
Additional Extension Period (as such terms are defined in Section 1(e) of the
Subscription Agreements, dated the date hereof between the Company and certain
investors (the "Subscription Agreements")), then the number of shares of Common
Stock which this Warrant represents the right to purchase shall be increased by
5% for each month of the Initial Extension Period, and 10% for each month of the
Additional Extension

                                     1



<PAGE>



Period, of which the Company avails itself. If the Company avails itself of the
Additional Extension Period (such term is defined in Section 1(e) of the
Subscription Agreements) then the Exercise Period following the Company's
initial public offering shall be deemed to have been defined in the preceding
sentence as the lesser of $3.50 and 50% of the initial public offering price per
share of Common Stock in the Company's initial public offering.

            Notwithstanding anything to the contrary contained herein, in the
event that (i) Barington Capital Group, L.P. ("Barington") commences its selling
efforts with respect to the offering contemplated under the letter of intent
between the Company and Barington dated July 23, 1996 with respect to an initial
public offering of the Company's securities (the "Letter of Intent"), and is
either unable to sell the full amount of such offering or is unable to sell such
offering within the price range set forth in the Letter of Intent, and (ii) the
Company consummates an alternative financing from an unrelated party in which
the Notes (as hereinafter defined) and any accrued interest thereon are paid in
full prior to the Time-Based Maturity Date (as such term is defined in the
Subscription Agreement pursuant to which this Warrant was issued by the
Company), without taking into account any extensions thereof, then the exercise
price hereunder shall be adjusted to the same per share price paid by the
investors in any such alternate financing.

            This Warrant is the warrant or one of the warrants (collectively,
including any warrants issued upon the exercise or transfer of any such warrants
in whole or in part, the "Warrants") issued pursuant to an offering (the
"Offering") by the Company of units, each consisting of (i) a $100,000 senior
secured promissory note (collectively, with all notes included in the units, the
"Notes"), and (ii) a warrant to purchase 25,000 shares of Common Stock, pursuant
to a Confidential Private Placement Memorandum, dated August 15, 1996, as it may
be amended or supplemented (the "Memorandum"). As used herein the term "this
Warrant" shall mean and include this Warrant and any Warrant or Warrants
hereafter issued as a consequence of the exercise or transfer of this Warrant in
whole or in part.

            The number of shares of Common Stock issuable upon exercise of the
Warrants (the "Warrant Shares") and the Exercise Price may be adjusted from time
to time as hereinafter set forth.

            1. (a) This Warrant may be exercised during the Exercise Period, as
to the whole or any lesser number of whole Warrant Shares, by the surrender of
this Warrant (with the election at the end hereof duly executed) to the Company
at its office at One Lower Ragsdale Drive, I-250, Monterey, CA 93940, or at such
other place as is designated in writing by the Company. Subject to Section 1(b)
hereof, such executed election must be accompanied by payment in an amount equal
to the

                                     2



<PAGE>



Exercise Price multiplied by the number of Warrant Shares for which this Warrant
is being exercised. Such payment may be made by certified or bank cashier's
check payable to the order of the Company, or as provided in Section 1(b)
hereof, or as otherwise provided in Section 1(b) hereof.

                  (b) All or any part of this Warrant may be exercised on a
"cashless" basis, by stating in the Exercise Notice such intention and either
(x) the maximum number (the "Maximum Number") of shares of Common Stock the
Holder desires to purchase in consideration of cancellation of Warrants in
payment for such exercise, or (y) the amount of then outstanding principal and
accrued interest under Notes submitted with such Exercise Notice, to be deemed
to be prepaid pursuant to such exercise. The number of shares of Common Stock
the Holder shall receive (the "Cashless Exercise Number") upon such exercise
pursuant to clause (x) of this Section 1(b) shall equal the difference between
the Maximum Number and the quotient that is obtained when the product of the
Maximum Number and the then current Exercise Price is divided by the then
Current Market Price per share (as hereinafter defined). The amount credited
toward the payment due from the Holder upon such exercise in respect of
prepayment of Notes pursuant to clause (y) of this Section 1(b) shall equal the
amount of principal and interest deemed prepaid thereby.

            2. Upon each exercise of the Holder's rights to purchase Warrant
Shares, the Holder shall be deemed to be the holder of record of the Warrant
Shares issuable upon such exercise, notwithstanding that the transfer books of
the Company shall then be closed or certificates representing such Warrant
Shares shall not then have been actually delivered to the Holder. As soon as
practicable after each such exercise of this Warrant, the Company shall issue
and deliver to the Holder a certificate or certificates for the Warrant Shares
issuable upon such exercise, registered in the name of the Holder or its
designee. If this Warrant should be exercised in part only, the Company shall,
upon surrender of this Warrant for cancellation, execute and deliver a new
Warrant evidencing the right of the Holder to purchase the balance of the
Warrant Shares (or portions thereof) subject to purchase hereunder.

            3. (a) Any Warrants issued upon the transfer or exercise in part of
this Warrant shall be numbered and shall be registered in a Warrant Register as
they are issued. The Company shall be entitled to treat the registered holder of
any Warrant on the Warrant Register as the owner in fact thereof for all
purposes and shall not be bound to recognize any equitable or other claim to or
interest in such Warrant on the part of any other person, and shall not be
liable for any registration or transfer of Warrants which are registered or to
be registered in the name of a fiduciary or the nominee of a fiduciary unless
made with the actual knowledge that a fiduciary or nominee is committing a
breach of trust in requesting such registration or transfer, or with the
knowledge of such facts that its

                                     3



<PAGE>



participation therein amounts to bad faith. This Warrant shall be transferable
only on the books of the Company upon delivery thereof duly endorsed by the
Holder or by his duly authorized attorney or representative, or accompanied by
proper evidence of succession, assignment, or authority to transfer. In all
cases of transfer by an attorney, executor, administrator, guardian, or other
legal representative, duly authenticated evidence of his or its authority shall
be produced. Upon any registration of transfer, the Company shall deliver a new
Warrant or Warrants to the person entitled thereto. This Warrant may be
exchanged, at the option of the Holder thereof, for another Warrant, or other
Warrants of different denominations, of like tenor and representing in the
aggregate the right to purchase a like number of Warrant Shares (or portions
thereof), upon surrender to the Company or its duly authorized agent.
Notwithstanding the foregoing, the Company shall have no obligation to cause
Warrants to be transferred on its books to any person if, in the opinion of
counsel to the Company, such transfer does not comply with the provisions of the
Securities Act of 1933, as amended (the "Act"), and the rules and regulations
thereunder.

                  (b) The Holder acknowledges that he has been advised by the
Company that neither this Warrant nor the Warrant Shares have been registered
under the Act, that this Warrant is being or has been issued and the Warrant
Shares may be issued on the basis of the statutory exemption provided by Section
4(2) of the Act or Regulation D promulgated thereunder, or both, relating to
transactions by an issuer not involving any public offering, and that the
Company's reliance thereon is based in part upon the representations made by the
original Holder in the original Holder's Subscription Agreement executed and
delivered in accordance with the terms of the Offering (the "Subscription
Agreement"). The Holder acknowledges that he has been informed by the Company
of, or is otherwise familiar with, the nature of the limitations imposed by the
Act and the rules and regulations thereunder on the transfer of securities. In
particular, the Holder agrees that no sale, assignment or transfer of this
Warrant or the Warrant Shares issuable upon exercise hereof shall be valid or
effective, and the Company shall not be required to give any effect to any such
sale, assignment or transfer, unless (i) the sale, assignment or transfer of
this Warrant or such Warrant Shares is registered under the Act, it being
understood that neither this Warrant nor such Warrant Shares are currently
registered for sale and that the Company has no obligation or intention to so
register this Warrant or such Warrant Shares except as specifically provided
herein, or (ii) this Warrant or such Warrant Shares are sold, assigned or
transferred in accordance with all the requirements and limitations of Rule 144
under the Act, it being understood that Rule 144 is not available at the time of
the original issuance of this Warrant for the sale of this Warrant or such
Warrant Shares and that there can be no assurance that Rule 144 sales will be
available at any subsequent time, or (iii) such sale, assignment, or transfer is
otherwise exempt from registration under the Act.

                                     4

            4. The Company shall at all times reserve and keep available out of
its authorized and unissued Common Stock, solely for the purpose of providing
for the exercise of the rights to purchase all Warrant Shares granted pursuant
to the Warrants, such number of shares of Common Stock as shall, from time to
time, be sufficient therefor. The Company covenants that all shares of Common
Stock issuable upon exercise of this Warrant, upon receipt by the Company of the
full Exercise Price therefor, shall be validly issued, fully paid,
nonassessable, and free of preemptive rights.

            5. (a) In case the Company shall at any time after the date this
Warrant is first issued (i) declare a dividend on the outstanding Common Stock
payable in shares of its capital stock, (ii) subdivide the outstanding Common
Stock, or (iii) combine the outstanding Common Stock into a smaller number of
shares, then, in each case, the Exercise Price, and the number of Warrant Shares
issuable upon exercise of this Warrant, in effect at the time of the record date
for such dividend or of the effective date of such subdivision, or combination,
shall be proportionately adjusted so that the Holder after such time shall be
entitled to receive the aggregate number and kind of shares for such
consideration which, if such Warrant had been exercised immediately prior to
such time at the then-current exercise price, he would have owned upon such
exercise and been entitled to receive by virtue of such dividend, subdivision,
or combination. Such adjustment shall be made successively whenever any event
listed above shall occur.

                  (b) In case the Company shall issue or fix a record date for
the issuance to all holders of Common Stock of rights, options, or warrants to
subscribe for or purchase Common Stock (or securities convertible into or
exchangeable for Common Stock) at a price per share (or having a conversion or
exchange price per share, if a security convertible into or exchangeable for
Common Stock) less than the Current Market Price per share of Common Stock on
such record date, then, in each case, the Exercise Price shall be adjusted by
multiplying the Exercise Price in effect immediately prior to such record date
by a fraction, the numerator of which shall be the number of shares of Common
Stock outstanding on such record date plus the number of shares of Common Stock
which the aggregate offering price of the total number of shares of Common Stock
so to be offered (or the aggregate initial conversion or exchange price of the
convertible or exchangeable securities so to be offered) would purchase at such
Current Market Price and the denominator of which shall be the number of shares
of Common Stock outstanding on such record date plus the number of additional
shares of Common Stock to be offered for subscription or purchase (or into which
the convertible or exchangeable securities so to be offered are initially
convertible or exchangeable); provided, however, that no such adjustment shall
be made which results in an increase in the Exercise Price. Such adjustment
shall become effective at the close of business on such record date; provided,
however, that, to the extent the shares of Common

                                     5



<PAGE>



Stock (or securities convertible into or exchangeable for shares of Common
Stock) are not delivered, the Exercise Price shall be readjusted after the
expiration of such rights, options, or warrants (but only with respect to
Warrants exercised after such expiration), to the Exercise Price which would
then be in effect had the adjustments made upon the issuance of such rights,
options, or warrants been made upon the basis of delivery of only the number of
shares of Common Stock (or securities convertible into or exchangeable for
shares of Common Stock) actually issued. In case any subscription price may be
paid in a consideration part or all of which shall be in a form other than cash,
the value of such consideration shall be as determined in good faith by the
board of directors of the Company, whose determination shall be conclusive
absent manifest error. Shares of Common Stock owned by or held for the account
of the Company or any majority-owned subsidiary shall not be deemed outstanding
for the purpose of any such computation.

                  (c) In case the Company shall distribute to all holders of
Common Stock (including any such distribution made to the stockholders of the
Company in connection with a consolidation or merger in which the Company is the
continuing corporation) evidences of its indebtedness, cash (other than any cash
dividend which, together with any cash dividends paid within the 12 months prior
to the record date for such distribution, does not exceed 5% of the Current
Market Price at the record date for such distribution) or assets (other than
distributions and dividends payable in shares of Common Stock), or rights,
options, or warrants to subscribe for or purchase Common Stock, or securities
convertible into or changeable for shares of Common Stock (excluding those with
respect to the issuance of which an adjustment of the Exercise Price is provided
pursuant to section 5(b) hereof), then, in each case, the Exercise Price shall
be adjusted by multiplying the Exercise Price in effect immediately prior to the
record date for the determination of stockholders entitled to receive such
distribution by a fraction, the numerator of which shall be the Current Market
Price per share of such class of Common Stock on such record date, less the fair
market value (as determined in good faith by the board of directors of the
Company, whose determination shall be conclusive absent manifest error) of the
portion of the evidences of indebtedness or assets so to be distributed, or of
such rights, options, or warrants or convertible or exchangeable securities, or
the amount of such cash, applicable to one share, and the denominator of which
shall be such Current Market Price per share of Common Stock. Such adjustment
shall become effective at the close of business on such record date.

                  (d) In case the Company shall issue shares of Common Stock or
rights, options, or warrants to subscribe for or purchase Common Stock, or
securities convertible into or exchangeable for Common Stock (excluding shares,
rights, options, warrants, or convertible or exchangeable securities issued or
issuable (i) in any of the transactions with respect

                                     6



<PAGE>



to which an adjustment of the Exercise Price is provided pursuant to Sections
5(a), 5(b), or 5(c) above, (ii) upon any issuance of securities pursuant to the
Offering or the proposed initial public offering or the exercise of securities
so issued, (iii) upon exercise of the Warrants, (iv) upon issuance or exercise
of any warrants issued to Barington or its designees in connection with the
Offering or the public offering proposed to be made as described in the
Memorandum,(v) upon adjustment of the number of shares of Common Stock issuable
upon exercise of the Warrants pursuant to the Preamble hereof, (vi) upon
issuance or exercise of up to 391,000 stock options granted or to be granted to
the directors, consultants or employees of the Company pursuant to any stock
option plan in effect on the date of the issuance of this Warrant or pursuant to
up to 60,000 stock options issued to directors of the Company prior to the date
hereof, (vii) upon exercise of the certain 468,242 warrants currently held by
Thinking Technologies, L.P. or (viii) upon issuance, prior to the initial public
offering of the Company, or exercise of stock options to purchase up to 15,000
shares of common stock to a non-affiliate of the Company at an exercise price
not lower than $1.00 per share) at a price per share (determined, in the case of
such rights, options, warrants, or convertible or exchangeable securities, by
dividing (x) the total amount received or receivable by the Company in
consideration of the sale and issuance of such rights, options, warrants, or
convertible or exchangeable securities, plus the minimum aggregate consideration
payable to the Company upon exercise, conversion, or exchange thereof, by (y)
the maximum number of shares covered by such rights, options, warrants, or
convertible or exchangeable securities) lower than the Current Market Price per
share of Common Stock in effect immediately prior to such issuance, then the
Exercise Price shall be reduced on the date of such issuance to a price
(calculated to the nearest cent) determined by multiplying the Exercise Price in
effect immediately prior to such issuance by a fraction, (1) the numerator of
which shall be an amount equal to the sum of (A) the number of shares of Common
Stock outstanding immediately prior to such issuance plus (B) the quotient
obtained by dividing the consideration received by the Company upon such
issuance by such Current Market Price, and (2) the denominator of which shall be
the total number of shares of Common Stock outstanding immediately after such
issuance; provided, however, that no such adjustment shall be made which results
in an increase in the Exercise Price. For the purposes of such adjustments, the
maximum number of shares which the holders of any such rights, options,
warrants, or convertible or exchangeable securities shall be entitled to
initially subscribe for or purchase or convert or exchange such securities into
shall be deemed to be issued and outstanding as of the date of such issuance,
and the consideration received by the Company therefor shall be deemed to be the
consideration received by the Company for such rights, options, warrants, or
convertible or exchangeable securities, plus the minimum aggregate consideration
or premiums stated in such rights, options, warrants, or convertible or
exchangeable securities to be paid

                                     7

for the shares covered thereby. No further adjustment of the Exercise Price
shall be made as a result of the actual issuance of shares of Common Stock on
exercise of such rights, options, or warrants or on conversion or exchange of
such convertible or exchangeable securities. On the expiration or the
termination of such rights, options, or warrants, or the termination of such
right to convert or exchange, the Exercise Price shall be readjusted (but only
with respect to Warrants exercised after such expiration or termination) to such
Exercise Price as would have obtained had the adjustments made upon the issuance
of such rights, options, warrants, or convertible or exchangeable securities
been made upon the basis of the delivery of only the number of shares of Common
Stock actually delivered upon the exercise of such rights, options, or warrants
or upon the conversion or exchange of any such securities; and on any change of
the number of shares of Common Stock deliverable upon the exercise of any such
rights, options, or warrants or conversion or exchange of such convertible or
exchangeable securities or any change in the consideration to be received by the
Company upon such exercise, conversion, or exchange, including, without
limitation, a change resulting from the antidilution provisions thereof. In case
the Company shall issue shares of Common Stock or any such rights, options,
warrants, or convertible or exchangeable securities for a consideration
consisting, in whole or in part, of property other than cash or its equivalent,
then the "price per share" and the "consideration received by the Company" for
purposes of the first sentence of this Section 5(d) shall be as determined in
good faith by the board of directors of the Company, whose determination shall
be conclusive absent manifest error. Shares of Common Stock owned by or held for
the account of the Company or any majority-owned subsidiary shall not be deemed
outstanding for the purpose of any such computation.

                  (e) For the purpose of any computation under this Section 5 or
Section 1, the Current Market Price per share of Common Stock on any date shall
be deemed to be the average of the daily closing prices for the 30 consecutive
trading days immediately preceding the date in question. The closing price for
each day shall be the last reported sales price regular way or, in case no such
reported sale takes place on such day, the closing bid price regular way, in
either case on the principal national securities exchange (including, for
purposes hereof, the NASDAQ National Market) on which the Common Stock is listed
or admitted to trading or, if the Common Stock is not listed or admitted to
trading on any national securities exchange, the highest reported bid price for
the Common Stock as furnished by the National Association of Securities Dealers,
Inc. through NASDAQ or a similar organization if NASDAQ is no longer reporting
such information. If on any such date the Common Stock is not listed or admitted
to trading on any national securities exchange and is not quoted by NASDAQ or
any similar organization, the fair value of a share of Common Stock on such
date, as determined in good faith by the board of directors of

                                     8



<PAGE>



the Company, whose determination shall be conclusive absent manifest error,
shall be used.

                  (f) No adjustment in the Exercise Price shall be required if
such adjustment is less than $.05; provided, however, that any adjustments which
by reason of this Section 5 are not required to be made shall be carried forward
and taken into account in any subsequent adjustment. All calculations under this
Section 5 shall be made to the nearest cent or to the nearest one-thousandth of
a share, as the case may be.

                  (g) In any case in which this Section 5 shall require that an
adjustment in the Exercise Price be made effective as of a record date for a
specified event, the Company may elect to defer, until the occurrence of such
event, issuing to the Holder, if the Holder exercised this Warrant after such
record date, the shares of Common Stock, if any, issuable upon such exercise
over and above the shares of Common Stock, if any, issuable upon such exercise
on the basis of the Exercise Price in effect prior to such adjustment; provided,
however, that the Company shall deliver to the Holder a due bill or other
appropriate instrument evidencing the Holder's right to receive such additional
shares upon the occurrence of the event requiring such adjustment.

                  (h) Upon each adjustment of the Exercise Price as a result of
the calculations made in Sections 5(b), 5(c), or 5(d) hereof, this Warrant shall
thereafter evidence the right to purchase, at the adjusted Exercise Price, that
number of shares (calculated to the nearest thousandth) obtained by dividing (A)
the product obtained by multiplying the number of shares purchasable upon
exercise of this Warrant prior to adjustment of the number of shares by the
Exercise Price in effect prior to adjustment of the Exercise Price by (B) the
Exercise Price in effect after such adjustment of the Exercise Price.

                  (i) Whenever there shall be an adjustment as provided in this
Section 5, the Company shall promptly cause written notice thereof to be sent by
certified mail, postage prepaid, to the Holder, at its address as it shall
appear in the Warrant Register, which notice shall be accompanied by an
officer's certificate setting forth the number of Warrant Shares purchasable
upon the exercise of this Warrant and the Exercise Price after such adjustment
and setting forth a brief statement of the facts requiring such adjustment and
the computation thereof, which officer's certificate shall be conclusive
evidence of the correctness of any such adjustment absent manifest error.

                  (j) The Company shall not be required to issue fractions of
shares of Common Stock or other capital stock of the Company upon the exercise
of this Warrant. If any fraction of a share would be issuable on the exercise of
this Warrant (or specified portions thereof), the Company shall purchase such
fraction for an amount in cash equal to the same fraction of the

                                     9



<PAGE>



Current Market Price of such share of Common Stock on the date of exercise of
this Warrant.

            6. (a) In case of any consolidation with or merger of the Company
with or into another corporation (other than a merger or consolidation in which
the Company is the surviving or continuing corporation), or in case of any sale,
lease, or conveyance to another corporation of the property and assets of any
nature of the Company as an entirety or substantially as an entirety, such
successor, leasing, or purchasing corporation, as the case may be, shall (i)
execute with the Holder an agreement providing that the Holder shall have the
right thereafter to receive upon exercise of this Warrant solely the kind and
amount of shares of stock and other securities, property, cash, or any
combination thereof receivable upon such consolidation, merger, sale, lease, or
conveyance by a holder of the number of shares of Common Stock for which this
Warrant might have been exercised immediately prior to such consolidation,
merger, sale, lease, or conveyance, and (ii) make effective provision in its
certificate of incorporation or otherwise, if necessary, to effect such
agreement. Such agreement shall provide for adjustments which shall be as nearly
equivalent as practicable to the adjustments in Section 5.

                  (b) In case of any reclassification or change of the shares of
Common Stock issuable upon exercise of this Warrant (other than a change in par
value or from no par value to a specified par value, or as a result of a
subdivision or combination, but including any change in the shares into two or
more classes or series of shares), or in case of any consolidation or merger of
another corporation into the Company in which the Company is the continuing
corporation and in which there is a reclassification or change (including a
change to the right to receive cash or other property) of the shares of Common
Stock (other than a change in par value, or from no par value to a specified par
value, or as a result of a subdivision or combination, but including any change
in the shares into two or more classes or series of shares), the Holder shall
have the right thereafter to receive upon exercise of this Warrant solely the
kind and amount of shares of stock and other securities, property, cash, or any
combination thereof receivable upon such reclassification, change,
consolidation, or merger by a holder of the number of shares of Common Stock for
which this Warrant might have been exercised immediately prior to such
reclassification, change, consolidation, or merger. Thereafter, appropriate
provision shall be made for adjustments which shall be as nearly equivalent as
practicable to the adjustments in Section 5.

                  (c) The above provisions of this Section 6 shall similarly
apply to successive reclassifications and changes of shares of Common Stock and
to successive consolidations, mergers, sales, leases, or conveyances.

            7.    In case at any time the Company shall propose to:

                                     10



<PAGE>




                  (a) pay any dividend or make any distribution on shares of
Common Stock in shares of Common Stock or make any other distribution (other
than regularly scheduled cash dividends which are not in a greater amount per
share than the most recent such cash dividend) to all holders of Common Stock;
or

                  (b) issue any rights, warrants, or other securities to all
holders of Common Stock entitling them to purchase any additional shares of
Common Stock or any other rights, warrants, or other securities; or

                  (c) effect any reclassification or change of outstanding
shares of Common Stock, or any consolidation, merger, sale, lease, or conveyance
of property, described in Section 6 hereof; or

                  (d)   effect any liquidation, dissolution, or
winding-up of the Company; or

                  (e)   take any other action which would cause an
adjustment to the Exercise Price;

then, and in any one or more of such cases, the Company shall give written
notice thereof, by certified mail, postage prepaid, to the Holder at the
Holder's address as it shall appear in the Warrant Register, mailed at least 15
days prior to (i) the date as of which the holders of record of shares of Common
Stock to be entitled to receive any such dividend, distribution, rights,
warrants, or other securities are to be determined, (ii) the date on which any
such reclassification, change of outstanding shares of Common Stock,
consolidation, merger, sale, lease, conveyance of property, liquidation,
dissolution, or winding-up is expected to become effective, and the date as of
which it is expected that holders of record of shares of Common Stock shall be
entitled to exchange their shares for securities or other property, if any,
deliverable upon such reclassification, change of outstanding shares,
consolidation, merger, sale, lease, conveyance of property, liquidation,
dissolution, or winding-up, or (iii) the date of such action which would require
an adjustment to the Exercise Price.

            8. The issuance of any shares or other securities upon the exercise
of this Warrant, and the delivery of certificates or other instruments
representing such shares or other securities, shall be made without charge to
the Holder for any tax or other charge in respect of such issuance. The Company
shall not, however, be required to pay any tax which may be payable in respect
of any transfer involved in the issue and delivery of any certificate in a name
other than that of the Holder and the Company shall not be required to issue or
deliver any such certificate unless and until the person or persons requesting
the issue thereof shall have paid to the Company the amount of such tax or shall
have established to the satisfaction of the Company that such tax has been paid.

                                     11



<PAGE>




            9. (a) If, at any time following the date of issuance of this
Warrant, the Company shall file a registration statement for the Company's
initial public offering with the Securities and Exchange Commission (the
"Commission") while any Registrable Securities (as hereinafter defined) are
outstanding, the Company shall, at the Company's sole expense (other than the
fees and disbursements of counsel for the then holders of any Registrable
Securities (the "Eligible Holders") and the underwriting discounts, if any,
payable in respect of the Registrable Securities sold by any Eligible Holder),
register or qualify all of the Registrable Securities of any Eligible Holders,
all to the extent necessary to permit the public offering and sale of the
Registrable Securities through the facilities of all securities exchanges and
the over-the-counter markets on which the Company's securities are traded, and
will use its best efforts through its officers, directors, auditors, and counsel
to cause such registration statement to become effective as promptly as
practicable. As used herein, "Registrable Securities" shall mean the Warrant
Shares, if any, which, in each case, have not been previously sold pursuant to a
registration statement or Rule 144 promulgated under the Act.


                  (b) If, at any time following the date of issuance of this
Warrant, the Company shall file a registration statement (other than for the
Company's initial public offering or any registration statement on Form S-4,
Form S-8, or any successor form) with the Commission while any Registrable
Securities are outstanding, and for any reason the Eligible Holders will not
otherwise have as of the effective date of such registration statement, the
benefit of an effective registration statement, including all required
amendments and supplements, filed pursuant to Section 9(a) or 9(c) hereof,
registering for sale the Registrable Securities, the Company shall give all the
Eligible Holders at least 30 days prior written notice of the filing of such
registration statement. If requested by any Eligible Holder in writing within 20
days after receipt of any such notice, the Company shall, at the Company's sole
expense (other than the fees and disbursements of counsel for the Eligible
Holders and the underwriting discounts, if any, payable in respect of the
Registrable Securities sold by any Eligible Holder), register or qualify all or,
at each Eligible Holder's option, any portion of the Registrable Securities of
any Eligible Holders who shall have made such request, concurrently with the
registration of such other securities, all to the extent necessary to permit the
public offering and sale of the Registrable Securities through the facilities of
all securities exchanges and the over-the-counter markets on which the Company's
securities are traded, and will use its best efforts through its officers,
directors, auditors, and counsel to cause such registration statement to become
effective as promptly as practicable. Notwithstanding the foregoing, if the
managing underwriter of any such offering shall advise the Company in writing
that, in its opinion, the distribution of all or a portion of the Registrable
Securities requested to be included

                                     12



<PAGE>



in the registration concurrently with the securities being registered by the
Company would materially adversely affect the distribution of such securities by
the Company for its own account, then any Eligible Holder who shall have
requested registration of his or its Registrable Securities shall not be
entitled to have such Eligible Holder's Registrable Securities (or the portions
thereof so designated by the managing underwriter) included in such registration
statement, provided that no such exclusion or reduction shall be made as to any
Registrable Securities if any securities of the Company are included in such
registration statement for the account of any person other than the Company and
any Eligible Holder unless the securities so included in such registration
statement for each such other person or persons requesting registration shall
have been reduced by the same proportion (based upon the total amount of
securities for which each person is entitled to request registration in such
registration statement) as the Registrable Securities which were requested to be
included in such registration were reduced.

                  (c) If, at any time after 12 months after the effective date
of the Company's initial public offering, and for any reason the Eligible
Holders do not otherwise have as of such date the benefit of an effective
registration statement, including all required amendments and supplements
thereto, filed pursuant to Section 9(a) or 9(b) hereof registering for sale the
Registrable Securities, the Company shall receive a written request, from
Eligible Holders who in the aggregate own (or which upon exercise of all
Warrants then outstanding would own) a majority of the total number of shares of
Common Stock then included (or upon such exercise would be included) in the
Registrable Securities then outstanding ("Majority Holders"), to register the
sale of all or part of such Registrable Securities, the Company shall, as
promptly as practicable, prepare and file with the Commission a registration
statement sufficient to permit the public offering and sale of the Registrable
Securities through the facilities of all securities exchanges and the
over-the-counter markets on which the Company's securities are traded, and will
use its best efforts through its officers, directors, auditors, and counsel to
cause such registration statement to become effective as promptly as
practicable; provided, however, that the Company shall only be obligated to file
one such registration statement for which all expenses incurred in connection
with such registration (other than the fees and disbursements of counsel for the
Eligible Holders and underwriting discounts, if any, payable in respect of the
Registrable Securities sold by the Eligible Holders) shall be borne by the
Company and one additional such registration statement for which all such
expenses shall be paid by the Eligible Holders electing to include Registrable
Securities in such Registration Statement. The Company shall not be obligated to
effect any registration of its securities pursuant to this Section 9(c) within
six months after the effective date of a previous registration statement
prepared and filed in accordance with Section 9(a) (in which Registrable

                                     13



<PAGE>



Securities could have been included), 9(b) or 9(c). Within ten business days
after receiving any request contemplated by this Section 9(b), the Company shall
send written notice to all the other Eligible Holders, advising each of them
that the Company is proceeding with such registration and offering to include
therein all or any portion of any such other Eligible Holder's Registrable
Securities, provided that the Company receives a written request to do so from
such Eligible Holder within 20 days after receipt by him or it of the Company's
notice.

                  (d) In the event of a registration pursuant to the provisions
of this Section 9, the Company shall use its best efforts to cause the
Registrable Securities so registered to be registered or qualified for sale
under the securities or blue sky laws of such jurisdictions as the Holder or
such holders may reasonably request; provided, however, that the Company shall
not by reason of this Section 9(d) be required to qualify to do business in any
state in which it is not otherwise required to qualify to do business or to file
a general consent to service of process.

                  (e) The Company shall keep effective any registration or
qualification contemplated by this Section 9 and shall from time to time amend
or supplement each applicable registration statement, preliminary prospectus,
final prospectus, application, document, and communication for such period of
time as shall be required to permit the Eligible Holders to complete the offer
and sale of the Registrable Securities covered thereby. The Company shall in no
event be required to keep any such registration or qualification in effect for a
period in excess of nine months from the date on which the Eligible Holders are
first free to sell such Registrable Securities taking into account any lock-up
agreement agreed to by such Holder, and the underwriter of the Company's initial
public offering; provided, however, that, if the Company is required to keep any
such registration or qualification in effect with respect to securities other
than the Registrable Securities beyond such period, the Company shall keep such
registration or qualification in effect as it relates to the Registrable
Securities for so long as such registration or qualification remains or is
required to remain in effect in respect of such other securities.

                  (f) In the event of a registration pursuant to the provisions
of this Section 9, the Company shall furnish to each Eligible Holder such
reasonable number of copies of the registration statement and of each amendment
and supplement thereto (in each case, including all exhibits), such reasonable
number of copies of each prospectus contained in such registration statement and
each supplement or amendment thereto (including each preliminary prospectus),
all of which shall conform to the requirements of the Act and the rules and
regulations thereunder, and such other documents, as any Eligible Holder may
reasonably request to facilitate the

                                     14



<PAGE>



disposition of the Registrable Securities included in such registration.

                  (g) In the event of a registration pursuant to the provisions
of this Section 9, the Company shall furnish each Eligible Holder of any
Registrable Securities so registered with an opinion of its counsel (reasonably
acceptable to the Eligible Holders) to the effect that (i) the registration
statement has become effective under the Act and no order suspending the
effectiveness of the registration statement, preventing or suspending the use of
the registration statement, any preliminary prospectus, any final prospectus, or
any amendment or supplement thereto has been issued, nor to the best knowledge
of such counsel has the Commission or any securities or blue sky authority of
any jurisdiction instituted or threatened to institute any proceedings with
respect to such an order, and (ii) the registration statement and the prospectus
included therein and any supplements or amendments thereto (except for financial
statements and related schedules and documents incorporated thereto by
reference, as to which such counsel need express no opinion) comply as to form
in all material respects with the Act, and the rules and regulations of the
Commission thereunder (except for financial statements and related schedules, as
to which counsel need express no opinion). In addition, such counsel shall state
that it has participated in conferences with officers and other representatives
of the Company, and representatives of independent accountants for the Company,
at which conferences such counsel made inquiries of such officers,
representatives and accountants; discussed the contents of the preliminary
prospectus; the registration statement; and the prospectus and related matters
were discussed and, although such counsel is not passing and does not assume any
responsibility for the accuracy, completeness or fairness, the statements
contained in the preliminary prospectus, the registration statement and the
prospectus, on the basis of the foregoing, no facts have come to the attention
of such counsel which lead it to believe that either the registration statement
or on any amendment thereto, at the time such registration statement or
amendment became effective or the preliminary prospectus or prospectus or
amendment or any supplement thereto as of the date of such opinion contained any
untrue statement of a material fact or omitted to state a material fact required
to be stated therein or necessary to make the statements therein not misleading
(it being understood that such counsel need express no opinion with respect to
the financial statements and schedules and other financial and statistical data
included in the preliminary prospectus, the registration statement, or
prospectus). The Company shall also furnish to each Eligible Holder a cold
comfort letter from the independent certified public accountants of the Company
in customary form and substance.

                  (h) In the event of a registration pursuant to the provision
of this Section 9, the Company and each Eligible Holder shall enter into a
cross-indemnity agreement and a

                                     15



<PAGE>



contribution agreement, each in customary form, with each underwriter, if any,
and, if requested, enter into an underwriting agreement containing conventional
representations, warranties, allocation of expenses, and customary closing
conditions, including, without limitation, opinions of counsel and accountants'
cold comfort letters, with any underwriter who acquires any Registrable
Securities.

                  (i) The Company agrees that, after the completion of its
initial public offering and until all the Registrable Securities have been sold
under a registration statement or pursuant to Rule 144 under the Act, it shall
keep current in filing all reports, statements and other materials required to
be filed with the Commission to permit holders of the Registrable Securities to
sell such securities under Rule 144.

                  (j) Except for rights granted to holders of the Warrants, any
warrants issued or issuable to Barington or its designees in connection with
this Offering or any other public or private offering, and the Notes, the
Company will not grant to any persons the right to request the Company to
register any securities of the Company without the written consent of the
Majority Holders, provided that the Company may grant such registration rights
to other persons so long as such rights are pari passu or subordinate to the
rights of the holders of the Registrable Securities.

            10. (a) Subject to the conditions set forth below, the Company
agrees to indemnify and hold harmless each Eligible Holder, its officers,
directors, partners, employees, agents, and counsel, and each person, if any,
who controls any such person within the meaning of Section 15 of the Act or
Section 20(a) of the Exchange Act, from and against any and all loss, liability,
charge, claim, damage, and expense whatsoever (which shall include, for all
purposes of this Section 10, without limitation, reasonable attorneys' fees and
any and all expense whatsoever incurred in investigating, preparing, or
defending against any litigation, commenced or threatened, or any claim
whatsoever, and any and all amounts paid in settlement of any claim or
litigation), as and when incurred, arising out of, based upon, or in connection
with, (i) any breach of any representation, warranty, covenant, or agreement of
the Company contained in any of the Notes or Warrants, or (ii) any untrue
statement or alleged untrue statement of a material fact contained (A) in any
registration statement, preliminary prospectus, or final prospectus (as from
time to time amended and supplemented), or any amendment or supplement thereto,
relating to the sale of any of the Registrable Securities, or (B) in any
application or other document or communication (in this Section 10 collectively
called an "application") executed by or on behalf of the Company or based upon
written information furnished by or on behalf of the Company filed in any
jurisdiction in order to register or qualify any of the Registrable Securities
under the securities or blue sky laws

                                     16



<PAGE>



thereof or filed with the Commission or any securities exchange; or any omission
or alleged omission to state a material fact required to be stated therein or
necessary to make the statements therein not misleading, unless such statement
or omission was made in reliance upon and in conformity with written information
furnished to the Company with respect to such Eligible Holder by or on behalf of
such person expressly for inclusion in any registration statement, preliminary
prospectus, or final prospectus, or any amendment or supplement thereto, or in
any application, as the case may be. The foregoing agreement to indemnify shall
be in addition to any liability the Company may otherwise have, including
liabilities arising under any of the Notes or Warrants.

            If any action is brought against any Eligible Holder or any of its
officers, directors, partners, employees, agents, or counsel, or any controlling
persons of such person (an "indemnified party") in respect of which indemnity
may be sought against the Company pursuant to the foregoing paragraph, such
indemnified party or parties shall promptly notify the Company in writing of the
institution of such action (but the failure so to notify shall not relieve the
Company from any liability under this Section 10(a) unless the Company shall
have been materially prejudiced by such failure or relieve the Company from any
liability other than pursuant to this Section 10(a)) and the Company shall
promptly assume the defense of such action, including the employment of counsel
(reasonably satisfactory to such indemnified party or parties) and payment of
expenses. Such indemnified party or parties shall have the right to employ its
or their own counsel in any such case, but the fees and expenses of such counsel
shall be at the expense of such indemnified party or parties unless the
employment of such counsel shall have been authorized in writing by the Company
in connection with the defense of such action or the Company shall not have
employed counsel reasonably satisfactory to such indemnified party or parties to
have charge of the defense of such action or such indemnified party or parties
shall have reasonably concluded that there may be one or more legal defenses
available to it or them or to other indemnified parties which are different from
or additional to those available to the Company, in any of which events such
fees and expenses shall be borne by the Company and the Company shall not have
the right to direct the defense of such action on behalf of the indemnified
party or parties. Anything in this Section 10 to the contrary notwithstanding,
the Company shall not be liable for any settlement of any such claim or action
effected without its written consent, which shall not be unreasonably withheld.
The Company agrees promptly to notify the Eligible Holders of the commencement
of any litigation or proceedings against the Company or any of its officers or
directors in connection with the sale of any Registrable Securities or any
preliminary prospectus, prospectus, registration statement, or amendment or
supplement thereto, or any application relating to any sale of any Registrable
Securities.


                                     17



<PAGE>



                  (b) The Holder agrees to indemnify and hold harmless the
Company, each director of the Company, each officer of the Company who shall
have signed any registration statement covering Registrable Securities held by
the Holder, each other person, if any, who controls the Company within the
meaning of Section 15 of the Act or Section 20(a) of the Exchange Act, and its
or their respective counsel, to the same extent as the foregoing indemnity from
the Company to the Eligible Holders in Section 10(a), but only with respect to
statements or omissions, if any, made in any registration statement, preliminary
prospectus, or final prospectus (as from time to time amended and supplemented),
or any amendment or supplement thereto, or in any application, in reliance upon
and in conformity with written information furnished to the Company with respect
to the Holder by or on behalf of the Holder expressly for inclusion in any such
registration statement, preliminary prospectus, or final prospectus, or any
amendment or supplement thereto, or in any application, as the case may be. If
any action shall be brought against the Company or any other person so
indemnified based on any such registration statement, preliminary prospectus, or
final prospectus, or any amendment or supplement thereto, or in any application,
and in respect of which indemnity may be sought against the Holder pursuant to
this Section 10(b), the Holder shall have the rights and duties given to the
Company, and the Company and each other person so indemnified shall have the
rights and duties given to the indemnified parties, by the provisions of Section
10(a).

                  (c) To provide for just and equitable contribution, if (i) an
indemnified party makes a claim for indemnification pursuant to Section 10(a) or
10(b) (subject to the limitations thereof) but it is found in a final judicial
determination, not subject to further appeal, that such indemnification may not
be enforced in such case, even though this Warrant expressly provides for
indemnification in such case, or (ii) any indemnified or indemnifying party
seeks contribution under the Act, the Exchange Act or otherwise, then the
Company (including for this purpose any contribution made by or on behalf of any
director of the Company, any officer of the Company who signed any such
registration statement, any controlling person of the Company, and its or their
respective counsel), as one entity, and the Eligible Holders of the Registrable
Securities included in such registration in the aggregate (including for this
purpose any contribution by or on behalf of an indemnified party), as a second
entity, shall contribute to the losses, liabilities, claims, damages, and
expenses whatsoever to which any of them may be subject, on the basis of
relevant equitable considerations such as the relative fault of the Company and
such Eligible Holders in connection with the facts which resulted in such
losses, liabilities, claims, damages, and expenses. The relative fault, in the
case of an untrue statement, alleged untrue statement, omission, or alleged
omission, shall be determined by, among other things, whether such statement,
alleged statement, omission, or alleged omission relates to information supplied
by the Company or by

                                     18



<PAGE>



such Eligible Holders, and the parties' relative intent, knowledge, access to
information, and opportunity to correct or prevent such statement, alleged
statement, omission, or alleged omission. The Company and the Holder agree that
it would be unjust and inequitable if the respective obligations of the Company
and the Eligible Holders for contribution were determined by pro rata or per
capita allocation of the aggregate losses, liabilities, claims, damages, and
expenses (even if the Eligible Holders and the other indemnified parties were
treated as one entity for such purpose) or by any other method of allocation
that does not reflect the equitable considerations referred to in this Section
10(c). In no case shall any Eligible Holder be responsible for a portion of the
contribution obligation imposed on all Eligible Holders in excess of its pro
rata share based on the number of shares of Common Stock owned (or which would
be owned upon exercise of all Registrable Securities) by it and included in such
registration as compared to the number of shares of Common Stock owned (or which
would be owned upon exercise of all Registrable Securities) by all Eligible
Holders and included in such registration. No person guilty of a fraudulent
misrepresentation (within the meaning of Section 11(f) of the Act) shall be
entitled to contribution from any person who is not guilty of such fraudulent
representation. For purposes of this Section 10(c), each person, if any, who
controls any Eligible Holder within the meaning of Section 15 of the Act or
Section 20(a) of the Exchange Act and each officer, director, partner, employee,
agent, and counsel of each such Eligible Holder or control person shall have the
same rights to contribution as each Eligible Holder or control person and each
person, if any, who controls the Company within the meaning of Section 15 of the
Act or Section 20(a) of the Exchange Act, each officer of the Company who shall
have signed any such registration statement, each director of the Company, and
its or their respective counsel shall have the same rights to contribution as
the Company, subject in each case to the provisions of this Section 10(c).
Anything in this Section 10(c) to the contrary notwithstanding, no party shall
be liable for contribution with respect to the settlement of any claim or action
effected without its written consent. This Section 10(c) is intended to
supersede any right to contribution under the Act, the Exchange Act or
otherwise.

            11. Unless registered pursuant to the provisions of Section 9
hereof, the Warrant Shares issued upon exercise of the Warrants shall be subject
to a stop transfer order and the certificate or certificates evidencing such
Warrant Shares shall bear the following legend:

                  "THE SHARES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN

            RECEIVES AN OPINION OF COUNSEL TO THE HOLDER OF SUCH SECURITIES,
            WHICH COUNSEL AND OPINION ARE REASONABLY SATISFACTORY TO THE
            COMPANY, THAT SUCH SECURITIES MAY BE OFFERED, SOLD, PLEDGED,

indemnity against any claim that may be made against the Company on account of

equity, or to any notice of meetings of stockholders or of any other proceedings
of the Company, except as provided in this Warrant.

            14. This Warrant shall be construed in accordance with the laws of
the State of New York applicable to contracts made and performed within such
State, without regard to principles governing conflicts of law.

            15. The Company irrevocably consents to the jurisdiction of the

document or instrument. In any such action or proceeding, the Company waives
personal service of any summons, complaint or other process and agrees that
service thereof may be made in accordance with Section 7(b) of the Subscription
Agreement. Within 30 days after such service, or such other time as may be
mutually agreed upon in writing by the

telex or similar telecommunications equipment) against receipt to the party to
whom it is to be given, (i) if to the Company, at One Lower Ragsdale Drive,

            17. No course of dealing and no delay or omission on the part of the
Holder in exercising any right or remedy shall operate as a waiver thereof or
otherwise prejudice the Holder's rights, powers or remedies. No right, power or
remedy conferred by this Warrant upon the Holder shall be exclusive of any other
right, power or remedy referred to herein or now or hereafter available at law,
in equity, by statute or otherwise, and all such remedies may be exercised
singly or concurrently.

            1.    Offering, Subscription Agreement and Security.
                  ----------------------------------------------

            This Note was issued by the Borrower in an offering (the "Offering")
of Units, each whole Unit consisting of one 10% Senior Secured Promissory Note
in the principal amount of $100,000 and a warrant to purchase 25,000 shares of
Common Stock, $.001 par value per share, of the Company (the "Common Stock"),
subject to adjustment as provided therein, made pursuant to a certain
Confidential Private Placement Memorandum dated August 15, 1996, as it may be
supplemented and amended (the "Memorandum"), and a subscription agreement (the
"Subscription Agreement") between the Borrower and the original Holder hereof.
The series of promissory notes issued in connection with the Offering is
referred to hereafter as the "Notes" and the warrants issued in connection with
the Offering are referred to hereafter as the "Warrants." The Notes are
collateralized by a security interest in certain of the assets of the Borrower
pursuant to a security agreement (the "Security Agreement") between the Borrower
and Barington Capital Group, L.P., as secured party and agent for the Holders of
the Notes (the "Secured Party"). The Notes also shall be entitled to the
benefits of any subordination and pledge agreement (the "Subordination
Agreement") executed and delivered by the holders (the "Junior Holders") of any
Junior Debt (as hereinafter defined).

            2.    Payments.
                  ---------

                  (a) Principal of, and any accrued and unpaid interest on, this
Note shall be due and payable in full on the Maturity Date. The "Maturity Date"
shall be the date which is the earliest of (i) August 28, 1997 subject to
extension as provided below,(the "Stated Maturity Date"), (ii) the day after the
date of the closing of the initial public offering of securities of the Borrower
or any subsidiary of the Borrower pursuant to a registration statement filed
with the Securities and Exchange Commission under the Act, and (iii) the date of
the closing of a sale (or the closing of the last of a series of sales) of
securities of the Borrower or any subsidiaries of the Borrower after the date
hereof (other than pursuant to the Memorandum), the gross proceeds of which, in
the aggregate, equal or exceed $1,825,000. The Company may elect to extend the
Stated Maturity Date for a period of six months (the "Initial Extension"),
during which interest shall continue to accrue on the Notes and the number of
shares of Common Stock purchasable upon exercise of the Warrants shall be
adjusted as provided therein. Following expiration of the Initial Extension, the
Company may elect to extend the Stated Maturity Date for an additional period of
up to six months, during which interest shall continue to accrue on the Notes
and the number of shares of Common Stock purchasable upon exercise of the
Warrants, and the exercise price thereof, shall be adjusted as provided therein,
and Barington shall exercise such powers as are

                                     2



<PAGE>



provided in Section 2 of the Subscription Agreement. The Company shall be deemed
to have elected to extend the Stated Maturity Date through any date at which the
Notes and any accrued interest thereon remain unpaid.

                  (b) Interest on this Note shall accrue from the most recent
Interest Payment Date to which interest has been paid or, if no interest has
been paid on this Note, from August 28, 1996, to but excluding the next Interest
Payment Date, and shall be payable in arrears on each Interest Payment Date.

                  (c) If any Interest Payment Date or the Maturity Date would
fall on a day that is not a Business Day (as defined below), the payment due on
such Interest Payment Date or Maturity Date will be made on the next succeeding
Business Day with the same force and effect as if made on the Interest Payment
Date or the Maturity Date, as the case may be. "Business Day" means any day
which is not a Saturday or Sunday and is not a day on which banking institutions
are generally authorized or obligated to close in the City of New York, New
York.

                  (d) The Borrower may, at its option, prepay all or any part of
the principal of this Note, without payment of any premium or penalty. The
Holder may elect upon written notice to the Borrower at any time to apply any or
all of the principal or interest then outstanding under this Note to payment of
the exercise price due upon exercise of any Warrant; such application of amounts
outstanding hereunder shall be deemed to be prepayment by the Borrower of such
amounts. All payments on this Note shall be applied first to accrued interest
hereon and the balance to the payment of principal hereof.

                  (e) Payments of principal and interest on this Note shall be
made by check sent to the Holder's address set forth above or to such other
address as the Holder may designate for such purpose from time to time by
written notice to the Borrower, in such coin or currency of the United States of
America as at the time of payment shall be legal tender for the payment of
public and private debts.

                  (f) The obligations to make the payments provided for in this
Note are absolute and unconditional and not subject to any defense, set-off,
counterclaim, rescission, recoupment or adjustment whatsoever. The Borrower
hereby expressly waives demand and presentment for payment, notice of
non-payment, notice of dishonor, protest, notice of protest and diligence in
taking any action to collect any amount called for hereunder, and shall be
directly and primarily liable for the payment of all sums owing and to be owing
hereon, regardless of and without any notice, diligence, act or omission with
respect to the collection of any amount called for hereunder.

            3.    Ranking of Note.
                  ----------------

                  (a) The Borrower, for itself, its successors and assigns,
covenants and agrees that the payment of the principal of and interest on this
Note is senior in right of payment to the payment of all existing and future
Junior Debt (as hereinafter defined). "Junior Debt" shall mean all existing and
future Indebtedness (as hereinafter defined) other than (i) the Indebtedness
represented by the Notes, and (ii) capital lease obligations existing on the
date hereof. "Indebtedness" shall mean (A) any liability of the Borrower for
borrowed money, (x) evidenced by a note, debenture, bond or other instrument of
indebtedness (including, without limitation, a purchase money obligation),
including any given in connection with the acquisition of property, assets or
service, or (y) for the payment of rent or other amounts relating to capitalized
lease obligations; (B) any liability of others described in Section 3(a)(A)
which the Borrower has guaranteed or which is otherwise its legal liability; and
(C) any modification, renewal, extension, replacement or refunding of any such
liability described in Section 3(a)(A) or (B); provided, that Indebtedness does
not include unsecured trade credit or up to $70,000 of indebtedness to Fred
Knoll existing as of the date hereof.

                  (b) The Borrower covenants and agrees to use its best efforts
to cause any current holder of Junior Debt and to cause any future holder of
Junior Debt to execute such subordination agreements, instruments or waivers as
may be reasonably necessary in the opinion of the Secured Party to reflect the
terms set forth herein.

                  (c) Except as provided in the Memorandum, until the payment in
full of all amounts of principal of and interest on the Notes, and all other
amounts owing under the Notes, the Security Agreement and the Subordination
Agreement, no payment may be made with respect to the principal of or interest
on or other amounts owing with respect to any Junior Debt, or in respect of any
redemption, retirement, purchase or other acquisition thereof.

                  (d) Upon any payment or distribution of the Collateral (as
defined in the Security Agreement) of the Borrower to creditors upon
dissolution, total or partial liquidation or reorganization of or similar
proceeding relating to the Borrower, the Holders of the Notes will be entitled
to receive payment in full before any holder of Junior Debt is entitled to
receive any payment.

            4.    Covenants.
                  ----------

            The Borrower covenants and agrees with the Holder that, so long as
any amount remains unpaid on the Notes, unless the consent of the Holders of a
majority of the principal amount outstanding under the Notes is obtained, the
Borrower:

                  (a) Shall not create, incur, or suffer to exist any
Indebtedness except (i) the Indebtedness represented by the Notes, (ii) Junior
Debt, the holders of which have duly executed a Subordination Agreement,
substantially in the form of Exhibit E to the Memorandum, (iii) an aggregate
total of $35,565.81 of capital lease obligations existing as of the date hereof,
and (iv) trade debt.

                  (b) Shall not create, incur or suffer to exist any mortgage,
lien, pledge, charge, security interest or encumbrance of any kind on any of its
property or assets (collectively, "Liens"), except (i) the Liens of the Security
Agreement, (ii) Liens for taxes not yet due or contested in good faith with
appropriate reserves maintained on the books of such Borrower, (iii) carriers',
warehousemen's, mechanics', and similar Liens and purchase money Liens arising
in the ordinary course of business which are not overdue for more than 90 days
or are being contested in good faith, (iv) easements, rights of way, zoning
restrictions, and similar Liens on real property, which in the aggregate are not
material and do not materially detract from the use of such property, (v) Liens
for Indebtedness permitted to be incurred or in existence under Sections
4(a)(ii),(iii),(iv), and (v)landlord Liens with respect to real property leased
by such Borrower.

                  (c) Shall not create, acquire, or maintain any subsidiaries
other than those referred to under the heading "The Company" in the Memorandum.

                  (d) Except as contemplated by the Memorandum, shall not pay
any dividend or make any distribution on, or purchase, redeem, or retire, any
shares of its capital stock or other securities or any warrants, options, or
other rights to reacquire any such shares or other securities, except that the
Borrower may pay dividends payable solely in shares of its capital stock.

                  (e)   Shall not change its primary line of business.

                  (f) Except as contemplated by the Memorandum, shall not (i)
enter into any merger or consolidation, (ii) liquidate, wind up its affairs or
dissolve, or (iii) except in the ordinary course of business, convey, sell,
lease, transfer or otherwise dispose of, or purchase or acquire, any business,
assets, capital stock (other than that issuable upon exercise of

                                     5

stock options pursuant to the Company's 1996 Stock Option Plan upon exercise of
the options described in Section 1 hereof) or other property.

                  (g) Except as contemplated by the Memorandum, shall not,
directly or indirectly, enter into any transaction with or for the benefit of an
affiliate (other than reasonable compensation, consistent with Section 4(h), for
services as an officer, director, partner or employee).

                  (h) Shall not in any manner increase the compensation of its
existing officers or directors and partners from the levels in effect on the
date of issuance of this Note other than (i) in the ordinary course of business
and in an amount not to exceed, in the aggregate, 5% annually or (ii) as
provided for in the Memorandum.

                  (i)   Shall use the proceeds of the Offering in
substantially the manner specified in the Memorandum.

Section 5(j), the principal amount then outstanding of, and the accrued interest
on, this Note shall automatically become immediately due and payable without
presentment, demand, protest or other formalities of any kind, all of which are
hereby expressly waived by the Borrower. Upon the occurrence of an Event of
Default referred to in Section 5(a) or 5(b), the Holders of not less than 50% in
principal amount of then outstanding Notes (excluding any Notes held by or for
the account of the Borrower or any affiliate of the Borrower), by notice in
writing given to the Borrower, may declare the entire principal amount then
outstanding of, and the accrued interest on, this Note to be due and payable
immediately, and upon any such declaration the same shall become and be due and
payable immediately, without presentation, demand, protest or other formalities
of any kind, all of which are expressly waived by the Borrower. Upon the
occurrence of an Event of Default other than one referred to in Sections 5(a),
(b) and (j), the Secured Party or the Holders of not less than 50% in principal
amount of then outstanding Notes (excluding any Notes held by or for the account
of the Borrower or any affiliate of the Borrower may declare the principal
amount then outstanding of, and the accrued interest on, the Notes to be due and
payable immediately, and upon such declaration the same

                                     9



<PAGE>



shall become due and payable immediately, without presentation, demand, protest
or other formalities of any kind, all of which are expressly waived by the
Borrower. In any case, the Holder or the Secured Party also may take any action
available to it under the Security Agreement or any instrument, agreement or
other document executed in connection herewith or therewith.

                  (b) The Holder may institute such actions or proceedings in
law or equity as it shall deem expedient for the protection of its rights and
may prosecute and enforce its claims against all assets of the Borrower, and in
connection with any such action or proceeding shall be entitled to receive from
the Borrower, payment of the principal amount of this Note plus accrued interest
to the date of payment plus reasonable expenses of collection, including,
without limitation, attorneys' fees and expenses.

            7.    Transfer.
                  ---------

                  (a) Any Notes issued upon the transfer of this Note shall be
numbered and shall be registered in a Note Register by the Borrower as they are
issued. The Borrower shall be entitled to treat the registered holder of any
Note on the Note Register as the owner in fact thereof for all purposes and
shall not be bound to recognize any equitable or other claim to or interest in
such Note on the part of any other person, and shall not be liable for any
registration or transfer of Notes which are registered or to be registered in
the name of a fiduciary or the nominee of a fiduciary unless made with the
actual knowledge that a fiduciary or nominee is committing a breach of trust in
requesting such registration or transfer, or with the knowledge of such facts
that its participation therein amounts to bad faith. This Note shall be
transferable only on the books of the Borrower upon delivery thereof to the
Borrower, duly endorsed by the Holder or by his duly authorized attorney or
representative, or accompanied by proper evidence of succession, assignment, or
authority to transfer. In all cases of transfer by an attorney, executor,
administrator, guardian, or other legal representative, duly authenticated
evidence of his or its authority shall be produced. Upon any registration of
transfer, the Borrower shall deliver a new Note or Notes to the person entitled
thereto. This Note may be exchanged, at the option of the Holder thereof, for
another Note, or other Notes of different denominations, of like tenor and
representing in the aggregate a like principal amount, upon surrender to the
Borrower, or its duly authorized agent. Notwithstanding the foregoing, the
Borrower shall have no obligation to cause Notes to be transferred on its books
to any person unless (i) the sale, assignment or transfer of the Notes is
registered under the Act; (ii) the Notes are sold, assigned or transferred in
accordance with all the requirements and limitations of Rule 144 under the Act;
or (iii) such sale, assignment or transfer is otherwise exempt from registration
under the securities laws,

                                     10



<PAGE>



and the Borrower receives an opinion of counsel to the Holder reasonably
acceptable to the Borrower to such effect.

                  (b) The Holder acknowledges that he has been advised that this
Note has not been registered under the Act, that the Note is being or has been
issued on the basis of the statutory exemption provided by Section 4(2) of the
Act or Regulation D promulgated thereunder, or both, relating to transactions by
an issuer not involving any public offering, and that the Borrower's reliance
thereon is based in part upon the representations made by the original Holder in
the original Holder's Subscription Agreement executed and delivered in
accordance with the terms of the Offering. The Holder acknowledges that he has
been informed of, or is otherwise familiar with, the nature of the limitations
imposed by the Act and the rules and regulations thereunder on the transfer of
securities. In particular, the Holder agrees that no sale, assignment or
transfer of the Note shall be valid or effective, and the Borrower shall not be
required to give any effect to any such sale, assignment or transfer, unless (i)
the sale, assignment or transfer of the Note is registered under the Act, it
being understood that the Note is not currently registered for sale and that the
Borrower has no obligation or intention to so register the Notes except as
specifically provided herein, or (ii) the Note is sold, assigned or transferred
in accordance with all the requirements and limitations of Rule 144 under the
Act, it being understood that Rule 144 is not available at the time of the
original issuance of this Note for the sale of the Note and that there can be no
assurance that Rule 144 sales will be available at any subsequent time, or (iii)
such sale, assignment, or transfer is otherwise exempt from registration under
the Act. The Holder further understands that an opinion of counsel and other
documents may be required to transfer the Note.

            8.    Miscellaneous.
                  --------------

Section 8(a) shall be deemed given at the time of receipt thereof.

Note has been lost, stolen, destroyed or mutilated, together with an indemnity

stolen, destroyed or mutilated Note, and upon reimbursement of the Borrower's
reasonable incidental expenses, the Borrower shall execute and deliver to the
Holder a new Note of like date, tenor and denomination.

                  (c) No course of dealing and no delay or omission on the part
of the Holder in exercising any right or remedy shall operate as a waiver
thereof or otherwise prejudice the Holder's rights, powers or remedies. No
right, power or remedy conferred by this Note upon the Holder shall be exclusive
of any other right, power or remedy referred to herein or now or hereafter
available at law, in equity, by statute or otherwise, and all such remedies may

                  (d) This Note may be amended only by a written instrument

                  (e) This Note shall be governed by and construed in accordance
with the laws of the State of New York, without giving effect to principles
governing conflict of laws.

                  (f) The Borrower irrevocably consents to the jurisdiction of
the courts of the State of New York and of any federal court located in such
State in connection with any action or proceeding arising out of or relating to
this Note, any document or instrument delivered pursuant to, in connection with
or simultaneously with this Note, or a breach of this Note or any such document
or instrument. In any such action or proceeding, the Borrower waives personal
service of any summons, complaint or other process and agrees that service
thereof may be made in accordance with Section 8(a). Within 30 days after such
service, or such other time as may be mutually agreed upon in writing by the
attorneys for the parties to such action or

(which amendment or waiver shall be binding upon all future Holders) only by
written consent or consents executed by the Company and the Holders of Notes
representing a majority (in principal amount) of the Notes issued to investors
pursuant to the Memorandum, provided, however that any waiver or amendment to

shall be effective only with respect to Notes the Holders of which have
consented thereto.

            IN WITNESS WHEREOF, the Borrower has caused this Note to be executed
and dated the day and year first above written.

Thinking Tools, Inc.
One Lower Ragsdale Drive, I-250
Monterey, CA  93940

Attention:  John Hiles
            President

Gentlemen:

      This letter, when executed by the parties hereto, will
constitute an agreement between Thinking Tools, Inc. (the
"Company") and Barington Capital Group, L.P. ("Barington"),
pursuant to which the Company agrees to retain Barington and
Barington agrees to be retained by the Company under the terms
and conditions set forth below:

      1.    The Company hereby retains Barington on a non-
exclusive basis to perform consulting services related to
corporate finance and other financial services matters, and
Barington hereby accepts such retention, for a term commencing
on the date hereof and ending on ________ __, 1998.  In this
regard, subject to the terms set forth below, Barington shall
furnish to the Company advice and recommendations with respect
to such aspects of the business and affairs of the Company as
the Company shall, from time to time, reasonably request upon
reasonable notice.

      2.    As compensation for the services described in
paragraph 1 above, the Company shall pay to Barington (i) a fee
equal to five percent of the first one million dollars of the
consideration paid or received by the Company (or any
stockholder, subsidiary or affiliate) in any Transaction (as
hereinafter defined) not covered by clause (ii) hereof, four
percent of the next million dollars of consideration so paid or
received, three percent of the next million dollars of
consideration so paid or received, two percent of the next
million dollars so paid or received and one percent of any
consideration so paid or received in excess of four million
dollars.  Except as provided in the penultimate sentence of this
Section 2, such fee shall be paid in cash, and (ii) 33% of all
consideration paid to any other investment banking firm or firms
in any Transaction in which the Company is represented by an
investment banking firm other than Barington at the closing of
the Transaction to which it relates.  The amount of




<PAGE>


Thinking Tools, Inc.
_________ __, 1996
Page 2


consideration paid in a Transaction shall include, for purposes
of calculating such fee, all forms of consideration paid by the
Company or any subsidiary or affiliate, or received by the
Company, its stockholders, or any subsidiary or affiliate of the
Company, including, but not limited to, cash, stock or evidence
of indebtedness, or any combination thereof.  Notwithstanding
the foregoing, Barington shall not be entitled to receive a fee
pursuant to this Section 2 for any Transaction which is
identified, negotiated and consummated by the Company without
the assistance or participation of Barington or any other
investment banking firm or other intermediary.  A "Transaction"
shall mean any transaction in which the Company or any
subsidiary or affiliate of the Company may be involved,
including, but not limited to, mergers, acquisitions, joint
ventures, sale of assets not in the ordinary course of business,
or sales or other issuances of any securities, to which the
provisions of Section 5 do not apply.

      3.    In addition, Barington shall hold itself ready to
assist the Company in evaluating and negotiating particular
contracts or projects, if requested to do so by the Company,
upon reasonable notice, and will undertake such evaluations and
negotiations under prior written agreement as to additional
compensation to be paid by the Company to Barington with respect
to such evaluations and negotiations.

      4.    All obligations of Barington contained herein shall be
subject to Barington's reasonable availability for such
performance, in view of the nature of the requested service and
the amount of notice received.  Barington shall devote such time
and effort to the performance of its duties hereunder as
Barington shall determine is reasonably necessary for such
performance.  Barington may look to such others for such factual
information, investment recommendations, economic advice and/or
research, upon which to base its advice to the Company
hereunder, as it shall deem appropriate.  The Company shall
furnish to Barington all information relevant to the performance
by Barington of its obligations under this Agreement, or
particular projects as to which Barington is acting as advisor,
which will permit Barington to know all facts material to the
advice to be rendered, and all materials or information
reasonably requested by Barington.  In the event that the
Company fails or refuses to furnish any such material or
information reasonably requested by Barington, and thus prevents
or impedes Barington's performance hereunder, any inability of
Barington to perform shall not be a breach of its obligations
hereunder.

      5.    For a period of three years from the later of the date
hereof or the date the offering is completed, Barington shall
have an irrevocable preferential right of first refusal to
purchase for its account or to sell for the account of the
Company or any subsidiary of or successor to the Company any
securities of the Company or any such subsidiary or successor of
the Company which the Company, any such subsidiary or successor
may seek to sell, whether pursuant to registration under the
Securities Act of 1933, as amended (the "Act") or otherwise.
The Company and, any such subsidiary or successor will consult
Barington with regard to any such offering and will offer
Barington the opportunity to purchase or sell any such
securities on terms not more favorable to the seller of such
securities than it or he can secure elsewhere.  If Barington
fails to accept such offer within 20 business days with respect
to an underwritten offering and within 5 business days with
respect to any other proposed sale, after the mailing of a
notice containing such offer by registered mail addressed to
Barington, then Barington shall have no further claim or right
with respect to the proposal contained in such notice.  If,
however, the terms of such proposal are subsequently modified,
the preferential right referred to herein shall apply to such
modified proposal as if the original proposal had not been made.
Barington's failure to exercise its preferential right with
respect to any particular proposal shall not affect its
preferential rights relative to future proposals.  Notwith-
standing the foregoing, in the event that such future sale
relates to an underwritten public offering to be lead managed by
an institutionally-based major bracket or large regional
underwriting firm, the Company shall be deemed to have satisfied
the right of first refusal contained herein if Barington is
given the right to participate in such offering as a co-manager
(right hand side) and receives at least 33% of the total
economics and 33% of the total number of shares being sold in,
such offering.

      6.    Subject to Section 7, nothing contained in this
Agreement shall limit or restrict the right of Barington or of
any partner, employee, agent or representative of Barington,
to be a partner, director, officer, employee, agent or
representative of, or to engage in, any other business, whether
or not of a similar nature to the Company's business, nor to
limit or restrict the right of Barington to render services of
any kind to any other corporation, firm, individual or
association.

      7.    Barington will hold, and will use its commercially
reasonable efforts to cause its officers, directors, employees,
consultants, advisors, and agents to hold, in confidence any




<PAGE>


Thinking Tools, Inc.
_________ __, 1996
Page 4


confidential information which the Company provides to Barington
pursuant to this Agreement.  Barington may disclose such
information to its officers, directors, employees, consultants,
advisors and agents, in connection with the services to be
rendered as contemplated by this Agreement, so long as such
persons are informed by Barington of the confidential nature of
such information and are directed by Barington to treat such
information confidentially in accordance herewith.
Notwithstanding the foregoing, Barington shall not be required
to maintain confidentiality with respect to information (i)
which is or becomes part of the public domain; (ii) of which
Barington had independent knowledge prior to disclosure to it by
the Company; (iii) which comes into the possession of Barington
in the normal and routine course of its own business from and
through independent non-confidential sources; or (iv) which is
required to be disclosed by Barington by governmental
requirements.  If Barington is requested or required (by oral
questions, interrogatories, requests for information or document
subpoenas, civil investigative demands, or similar process) to
disclose any confidential information supplied to it by the
Company, or the existence of other negotiations in the course of
its dealings with the Company or its representatives, Barington
shall, unless prohibited by law, promptly notify the Company of
such request(s) so that the Company may seek an appropriate
protective order.

      8.    Because Barington will be acting on your behalf, it is
its practice to receive indemnification.  A copy of Barington's
standard indemnification provisions (the "Indemnification
Provisions") is attached to this Agreement and is incorporated
herein and made a part hereof.

      9.    This Agreement may not be transferred, assigned or
delegated by any of the parties hereto without the prior written
consent of the other party hereto.

      10.   The failure or neglect of the parties hereto to
insist, in any one or more instances, upon the strict
performance of any of the terms or conditions of this Agreement,
or their waiver of strict performance of any of the terms or
conditions of this Agreement, shall not be construed as a waiver

                         INDEMNIFICATION PROVISIONS


      Thinking Tools, Inc. (the "Company") agrees to indemnify
and hold harmless Barington Capital Group, L.P. ("Barington")
against any and all losses, claims, damages, obligations,
penalties, judgments, awards, liabilities, costs, expenses and
disbursements (and any and all actions, suits, proceedings and
investigations in respect thereof and any and all legal and
other costs, expenses and disbursements in giving testimony or
furnishing documents in response to a subpoena or otherwise),
including, without limitation, the costs, expenses and
disbursements, as and when incurred, of investigating, preparing
or defending any such action, suit, proceeding or investigation
(whether or not in connection with litigation in which Barington
is a party), directly or indirectly, caused by, relating to,
based upon, arising out of, or in connection with Barington's
acting for the Company, including, without limitation, any act
or omission by Barington in connection with its acceptance of or
the performance or non performance of its obligations under the
Agreement, dated _______ __, 1996, between the Company and
Barington to which these indemnification provisions are attached
and form a part (the "Agreement"), except to the extent that any
such liability is found in a final judgment by a court of
competent jurisdiction (not subject to further appeal) to have
resulted primarily and directly from Barington's gross
negligence or willful misconduct.  The Company also agrees that
Barington shall not have any liability (whether direct or
indirect, in contract or tort or otherwise) to the Company for
or in connection with the engagement of Barington under the
Agreement, except to the extent that any such liability is found
in a final judgment by a court of competent jurisdiction (not
subject to further appeal) to have resulted primarily and
directly from Barington's gross negligence or willful
misconduct.

      These indemnification provisions shall be in addition to
any liability which the Company may otherwise have to Barington
or the persons indemnified below in this sentence and shall
extend to the following: Barington, its affiliated entities,
directors, partners, employees, legal counsel, agents and
controlling persons (within the meaning of the federal
securities laws), and the officers, directors, employees, legal
counsel, agents and controlling persons of any of them.  All
references to Barington in these indemnification provisions
shall be understood to include any and all of the foregoing.

      If any action, suit, proceeding or investigation is
commenced, as to which Barington proposes to demand
indemnification, it shall notify the Company with reasonable
promptness; provided, however, that any failure by Barington to
notify the Company shall not relieve the Company from its
obligations hereunder.  Barington shall have the right to retain
counsel of its own choice to represent it, and the Company shall




<PAGE>



pay the fees, expenses and disbursements of such counsel; and
such counsel shall, to the extent consistent with its
professional responsibilities, cooperate with the Company and
any counsel designated by the Company.  The Company shall be
liable for any settlement of any claim against Barington made
with the Company's written consent, which consent shall not be
unreasonably withheld.  The Company shall not, without the prior
written consent of Barington, settle or compromise any claim, or
permit a default or consent to the entry of any judgment in
respect thereof, unless such settlement, compromise or consent
includes, as a unconditional term thereof, the giving by the
claimant to Barington of an unconditional release from all
liability in respect of such claim.  In order to provide for
just and equitable contribution, if a claim for indemnification
pursuant to these indemnification provisions is made but it is
found in a final judgment by a court of competent jurisdiction
(not subject to further appeal) that such indemnification may
not be enforced in such case, even though the express provisions
hereof provide for indemnification in such case, then the
Company, on the one hand, and Barington, on the other hand,
shall contribute to the losses, claims, damages, obligations,
penalties, judgments, awards, liabilities, costs, expenses and
disbursements to which the indemnified persons may be subject in
accordance with the relative benefits received by the Company,
on the one hand, and Barington, on the other hand, and also the
relative fault of the Company, on the one hand, and Barington,
on the other hand, in connection with the statements, acts or
omissions which resulted in such losses, claims, damages,
obligations, penalties, judgments, awards, liabilities, costs,
expenses or disbursements and the relevant equitable
considerations shall also be considered.  No person found liable
for a fraudulent misrepresentation shall be entitled to
contribution from any person who is not also found liable for
such fraudulent misrepresentation.  Notwithstanding the
foregoing, Barington shall not be obligated to contribute any
amount hereunder that exceeds the amount of fees previously
received by Barington pursuant to the Agreement.

      Neither termination nor completion of the engagement of
Barington referred to above shall affect these indemnification
provisions which shall then remain operative and in full force
and effect.

         We consent to the use of our report included herein and to the
reference to our firm under the heading "Experts" in the prospectus.

         Our report dated August 16, 1996, except as to note 13 which is as of
August 28, 1996, contains an explanatory paragraph that states that the Company
has suffered recurring losses from operations and has a net capital deficiency
that raise substantial doubt about its ability to continue as a going concern.
The financial statements do not include any adjustments that might result from
the outcome of that uncertainty.
