                                  RISK FACTORS

     In addition to the other information in this Prospectus, the following
should be considered carefully in evaluating the Company and its business before
purchasing the Common Stock offered by this Prospectus.

FINANCIAL CONDITION OF THE COMPANY

On November 6, 1996, the Company amended and restated its revolving credit
agreement with a bank to borrow up to $5 million, to extend its term through
October 4, 1997 and to amend certain of the financial and operating covenants
and other provisions thereunder. In connection with the amendment, the Company
issued to the Bank a three-year warrant to purchase 25,000 shares of the
Company's Common Stock at an exercise price of $4.25 per share. The loan is
contingent upon meeting certain financial and operating covenants at the time
of any borrowing and over the life of the loan. The loan is secured by all of
the assets of the Company and any borrowing amounts are tied to a percentage of
qualified accounts receivable outstanding at the time of any borrowing. The
financial covenants, which were further amended in April 1997, include
attainment of specified levels of consolidated net income (loss) at the end of
each quarter, including net income of $250,000 for the quarter ended June 30,
1997 and each quarter thereafter, and specified levels of liquidity at the end
of each month. The Company was in compliance with all covenants as amended at
June 30, 1997 or has received a waiver from the bank as to any non-compliance.
At June 30, 1997, the borrowing base under the revolving credit agreement was
approximately $2.5 million. The Company had approximately $2.8 million
outstanding against the line of credit at that date and is currently working to
perfect certain international trade receivables in order to resolve the
shortfall. In July 1997, the Company raised $2 million in equity capital
through a private placement of Series C Convertible Preferred Stock and
Warrants to purchase Common Stock to one of the Selling Stockholders described
in this Prospectus. The Company expects to renew or renegotiate its revolving
credit agreement that expires on October 4, 1997. The Company is currently 
seeking additional equity investment on similar terms. The Company expects that
its existing cash balances, funds generated through operations, and the 
additional equity investment will provide sufficient cash resources to finance 
current operations and projected capital requirements through the end of 1997. 
Thereafter, the company's cash requirements will depend on the results of 
future operations, which cannot be foreseen. 

     The Company has been notified by The Nasdaq Stock Market, Inc. that it is
not in compliance with the net tangible asset requirement for continued
listing on the Nasdaq National Market. The Company has been given terms which
include raising additional equity, with which it must comply. If the Company is
not successful, its stock will be listed under the Nasdaq SmallCap Market. The
Company intends to meet this requirement by raising additional equity.

RESULTS OF RECENT OPERATIONS

     The Company's operating results for the three years ended June 30, 1996 the
six-month transitional period ended December 31, 1996 and the six months ended
June 30, 1997 were significantly adversely affected by several factors. In July
1996, the Company completed its merger with Cadre Technologies, Inc., which
resulted in a $6.3 million charge to operations for the quarter ended September
30, 1996 to reflect costs associated with the combining of the two companies,
transaction fees, and other costs. In addition, the Company has continued to
invest heavily in its object-oriented and client/server-based products. The
Company's operating results continue to be affected by the market trends of the
Company's customers moving from mainframe development to client/server and
object-oriented solutions. The increased revenue growth of the Company's
client/server and object-oriented products has not been rapid enough to offset
the revenue decline of the Company's mainframe- based products.

     As the Company continues to make the transition from providing tools
focused solely on mainframe application development to supporting customers'
needs for a more open and flexible set of solutions aimed at the growing
client/server market, it faces many challenges. The Company plans to enhance its
product offerings through development efforts, strategic alliances and
acquisitions to improve its competitive position. 


                                       -4-

     On July 18, 1996, the Company completed its acquisition of Cadre
Technologies Inc. ("Cadre") under an Agreement and Plan of Merger dated March
25, 1996, by and among the Company, Cadre and B.C. Acquisition Corp., whereby
the Company agreed to acquire all of the outstanding capital stock of Cadre in
exchange for 4,716,442 shares of Cayenne common stock (the "merger"). The merger
was accounted for as a pooling-of-interests during the transition period ended
December 31, 1996. Effective upon the merger, the Company changed its name to
Cayenne Software, Inc. The Company acquired Cadre to expand its product
offerings to include structured analysis and design and object-oriented
technology and to expand its customer base. During the transition period ended
December 31, 1996, the Company incurred a charge of $6.3 million in conjunction
with the merger and to reflect costs associated with combining the operations of
the two companies, transaction fees, and other costs. Included in the charge
were $1.6 million of employee-related termination expenses for approximately 45
employees; $1.3 million of legal, accounting, investment banking, and other
professional fees; $1.4 million of facilities closure and consolidation
expenses; and $2 million of other expenses associated with the consolidation of
the two companies and the name change.

SIGNIFICANT RECENT LOSSES; SHORT PRIOR HISTORY OF PROFITABILITY

     Cayenne received its first venture financing in the third quarter of
fiscal 1986, shipped its first software products in the fourth quarter of fiscal
1988, and did not reach profitability until the first quarter of fiscal 1991.
Cayenne incurred net losses of $13.2 million, $24.9 million, and $11.3 million
in Fiscal 1994, Fiscal 1995, and Fiscal 1996, respectively, and a net loss of
$6.4 million for the six months ended December 31, 1996, which included a $6.3
million charge for restructuring and other costs in September 1996. For the six
months ended June 30, 1997 the Company recorded a net loss of $1.8 million. A
reorganization of the Company's sales force during June 1997 resulted in a
longer sales cycle for software licenses and adversely effected profitability.
In September 1994, the first quarter of fiscal 1995, the Company recorded a
restructuring charge of approximately $2 million resulting from reductions in
staff and related facilities expenses and the termination of certain contracts.
During the quarter ended June 30, 1995, the Company also incurred approximately
$1.8 million in restructuring costs, which included a $0.9 million write-off of
redundant capitalized software, $0.8 million of employee related costs, and
$0.1 million of other costs related to the restructuring. In the quarter ended
December 31, 1995, the Company incurred an additional $1.7 million in
restructuring charges. Future operating results will depend on many factors,
including demand for Cayenne's products, Cayenne's ability to obtain major
orders, the level of competition, Cayenne's ability to develop and market new
products, and the ability of its officers and key employees to manage Cayenne's
business and control costs. There can be no assurance that revenue growth or
profitable operations on a quarterly or annual basis will be achieved during
1997 or in any subsequent fiscal year. 

CHANGING MARKETS

     The Company develops software tools that help software developers create
applications and integrate diverse information sources for large and small
software development projects. The products include modeling, database design
and development tools for object-oriented, data-driven and structured
application development approaches for use by large corporations, independent
software vendors and technical organizations. The products are targeted to the
object and relational application development needs of software development
teams in a scalable, workgroup-to-enterprise environment. The Company's products
are used to create real-time and embedded applications, three-tier client/server
applications, data warehouses, and internet/intranet solutions on a wide range
of platforms. The market in which Cayenne participates is characterized by
frequent and rapid changes in hardware and software technology and in customer
preferences; the Company has responded to these changes and will continue to do
so in the future. For information-intensive applications the computing
environment has migrated from centralized mainframe computers to personal
computer networks and related "client/server" technology, and it is now
incorporating internet/intranet environments. The Company has devoted much
effort to change its product mix in response to these market changes by: 1)
transitioning its


                                       -5-
   9
mainframe products to a client/server environment, 2) leading the software
industry in the structured to object- oriented design methodologies migration,
3) adding UML object modeling methodology to its OMT methodology, and 4)
internet enabling the Company's products. Cayenne's future success will depend
on its ability to enhance its current products and to develop and introduce new
products that accommodate advances in software and hardware technology and
changing customer requirements. 

     In July 1996, the Company acquired Cadre Technologies, Inc. and entered
into an additional industry segment focused on the creation and maintenance of
complex software systems, the problem addressed by Computer Aided Software
Engineering ("CASE") products. During the 1970s, a number of "structured"
techniques and methods were invented to replace earlier ad-hoc approaches to
software development. The analysis and design (as opposed to implementation)
techniques emphasize the building of abstract models to assist in the
understanding, planning, and implementation of a system. The rationale for
modeling is the same in software as it is in any engineering discipline; money
and effort are saved if problems are identified and dealt with early in the
engineering process.

     Structured analysis and structured design. In the early eighties, networks
of computer workstations made it feasible to partially automate the capture,
traversal, and analysis of engineering models by work groups. This technology
was rapidly adopted in the civil, mechanical, and electrical engineering
domains. The CASE market expanded quickly in the mid-to late-eighties, as did
the number of companies formed to service it. The high end of the market, with
its multi-user networked UNIX engineering workstation solution, found a home in
technically-oriented organizations, such as those in telecommunications,
aerospace and defense. The other end of the market focused on single-user,
personal computer ("PC") based products. These found early success in corporate
IS organizations, where PCs were widely used.

     The IS CASE market declined in the early nineties for a number of reasons.
While the IS software development market is large, commitment to structured
methods (and the attendant engineering discipline) was weak. Some CASE companies
made claims which the products were unable to deliver and soured the market.
Others were slow to respond to technology changes such as the shift to
client-server application development and object orientation (discussed further
below). The decline resulted in a number of market leaders closing or being
acquired. The technical market, where Cadre derived the majority of its
business, was affected by the contraction and consolidation in the defense
industry. Consequently, Cadre diversified its product line into the software
development process, including debugging, measurement and verification tools.

     Object oriented technology. In the meantime, the software development
community began to experiment with "object-oriented" technology, and in
particular, OO analysis, design and implementation techniques. The structured
techniques mentioned previously generally partition a system purely along
functional lines, i.e. in terms of what the system does. The OO approach
partitions a system into "objects", where each object encapsulates information
and those functions that operate on that information. The benefit of the OO
approach is that systems partitioned this way are more robust, more amenable to
change, and the objects are easier to reuse in other systems.

     Cadre started selling its first OO analysis and design products (based on
the method of developing software created by Shlaer-Mellor) in 1989. When market
momentum began to build around a related method called the Object Modeling
Technique ("OMT"), Cadre initially entered the market by reselling an OMT
product in 1993. This was replaced by the OMT tool developed by Westmount
Technology B.V., acquired by Cadre in 1995. In 1997, Cayenne introduced an
object oriented product line that uses the Unified Modeling Language ("UML")
methodology.

FLUCTUATIONS IN QUARTERLY PERFORMANCE

     Throughout its history, Cayenne's revenue has varied from quarter to
quarter, with the largest portion of revenue recognized in the fourth quarter of
each fiscal year. In the normal course of events, Cayenne may realize lower
revenue in the first quarter than in the preceding fourth quarter and also may
realize lower revenue in the third quarter than in the preceding second quarter.
Cayenne has also frequently recognized more revenue in the last month of each
quarter than in either of the preceding two months. Cayenne believes that these
quarterly and monthly patterns are partly attributable to Cayenne's sales
commission policies, which compensate sales personnel for meeting or exceeding
quarterly quotas, and to the budgeting and purchasing cycles of customers. In
addition, Cayenne's revenue and earnings have fluctuated historically, and may
fluctuate in the future, due to the timing of large individual orders. There
were no large orders ($1,000,000 or more) during the six months ended June 30,
1997. Cayenne usually has no significant backlog, and substantially all of its
product revenue in any quarter results from sales made in that quarter. If sales
do not close in a quarter as expected, Cayenne's results of operations for that
quarter would be adversely affected. Net income may be disproportionately
affected by a reduction in revenues because only a small portion of Cayenne's
expenses vary with revenues.

HIGHLY COMPETITIVE INDUSTRY; INCREASING COMPETITION; DEPENDENCE ON KEY PERSONNEL

     The market for Cayenne's software products is highly competitive, and
Cayenne expects competition to increase. Companies competing in related markets,
including hardware manufacturers, could seek to enter this market with software
products which offer functionality similar to that offered by Cayenne's
products. The computer aided software engineering ("CASE") market generally has
been adversely affected by competition from other programming support
environments. In addition, Cayenne expects to encounter additional competitors
as it expands its product line beyond the mainframe and structured analysis and
design markets into the client/server and object-oriented markets. Many of
Cayenne's existing and potential competitors have greater financial, technical
and other resources than Cayenne. In addition, mergers or other business
combinations among competitors could strengthen them and create larger companies
with broader product offerings, more extensive market influence and greater
resources. Maintaining and improving Cayenne's competitive position will require
continued investment by Cayenne in research and development, sales, and
marketing, particularly as Cayenne expands its product line beyond the mainframe
and structured analysis and design markets. There can be no assurance that
Cayenne will have sufficient resources to make that investment. Competitive
pressures could result in loss of market share, price reductions and increases
in expenses that could adversely affect Cayenne's business.

     Cayenne has experienced turnover in its personnel in the past including
certain executives and key management, technical, and sales employees. Cayenne's
future success will depend in large part upon its ability to attract and retain
skilled executives and management and technical personnel. Competition for such
personnel in the software industry continues to be intense. There can be no
assurance that Cayenne will be successful in attracting and retaining the
personnel it requires for its operations.

VOLATILITY OF SHARE PRICE

     Since the completion of Cayenne's initial public offering in November 1991,
the closing price of Cayenne Common Stock, as reported by the Nasdaq Stock
Market, has ranged from $1 3/4 to $37 3/4. The highest closing price of the
Common Stock as reported on the NASDAQ Stock Market during the Company's last
two completed fiscal years was $11.875 per share. See "Price Range of Common
Stock and Dividends." Announcements of technological innovations or new products
by Cayenne or its competitors, quarterly variations in Cayenne's operating
results, general factors affecting the computer software industry, and other


                                       -7-
   11
factors may cause the market price of Cayenne Common Stock to fluctuate
significantly in the future. In addition, in recent years the stock market has
experienced large price and volume fluctuations, which often have been unrelated
to the operating performance of specific companies or market sectors.

RISKS OF INTERNATIONAL OPERATIONS; RELIANCE ON DISTRIBUTORS

     Approximately 48%, 50%, 52%, 51% and 53% of Cayenne's revenues in fiscal
1994, 1995, and 1996, the six months ended December 31, 1996, and the six months
ended June 30, 1997, respectively, were attributable to international sales.

     The future contribution of sales from Cayenne's international subsidiaries
to its results of operations depends on Cayenne's success in maintaining
cost-effective direct marketing operations through Cayenne's wholly owned
subsidiaries in Australia, Germany, Italy, the Netherlands, Singapore, Spain,
and the United Kingdom. Sales in countries in which Cayenne continues to use
independent distributors will remain subject to the distributors' financial
condition and success, which cannot be controlled by Cayenne. Other risks
inherent in Cayenne's international business generally include exposure to
currency fluctuations, longer payment cycles, greater difficulties in accounts
receivable collection and the requirement of complying with a wide variety of
foreign laws.

DEPENDENCE ON PROPRIETARY TECHNOLOGY

     Cayenne's success is heavily dependent upon its proprietary software
technology. Cayenne relies principally on a combination of copyrights, trade
secrets and contractual rights to protect its proprietary technology. In
addition, Cayenne holds ten United States patents and currently has various
patent applications pending abroad. There can be no assurance that any patents
will be issued in respect of those applications, or that the steps taken by
Cayenne to protect its proprietary rights will be adequate to prevent
misappropriation of its technology or independent development by others of
similar technology. Although Cayenne believes that its products and technology
do not infringe on any existing proprietary rights of others, the use of patents
to protect software has increased, and there can be no assurance that third
parties will not assert infringement claims in the future. If any such claim
were to be asserted, it might involve costly and protracted litigation. No
assurance can be given that Cayenne would be successful in any such litigation
or that, if it were not successful, it would be able to license the disputed
proprietary rights on commercially reasonable terms.

ANTI-TAKEOVER EFFECT OF CERTAIN PROVISIONS OF CHARTER AND BY-LAWS, MASSACHUSETTS
LAW AND EMPLOYMENT AGREEMENTS

     The Cayenne Board has the authority to issue up to 1,600,000 shares of
preferred stock (including the 100,000 shares of Series C Convertible Preferred
Stock issued in July 1997) and to determine the price, rights, preferences,
privileges and restrictions, including voting rights, of those shares without
any further vote or action by the stockholders. The rights of the holders of
Cayenne Common Stock will be subject to, and may be adversely affected by, the
rights of the holders of any Cayenne preferred stock that may be issued in the
future. The issuance of Cayenne preferred stock, while providing desirable
flexibility in connection with possible acquisitions and other corporate
purposes, could have the effect of making it more difficult for a third party to
acquire a majority of the outstanding voting stock of Cayenne. In addition, the
classification of the Cayenne Board and certain other provisions of Cayenne's
Restated Articles of Organization (the "Cayenne Articles"), its Amended and
Restated By-Laws (the "Cayenne By-Laws") and Massachusetts law could delay or
frustrate the removal of incumbent directors and could make more difficult a
merger, tender offer or proxy contest involving Cayenne. Further, Cayenne and
certain of its current executive officers have entered into employment
agreements that become effective only upon the occurrence of certain "changes in
control." Other officers of the Company also have


                                       -8-
   12
arrangements providing them with severance payments and other benefits if their
employment is terminated without cause or, in some cases, in connection with a
change in control of the Company. While these agreements were intended by
Cayenne to limit further departures by executive officers, the agreements also
could have the effect of making a merger, tender offer or proxy contest more
difficult.

SHARES OF COMMON STOCK ELIGIBLE FOR FUTURE SALE

     Sales of a substantial number of shares of Cayenne Common Stock in the
public market could adversely affect the market price for the Cayenne Common
Stock. Sales of substantial amounts of Cayenne Common Stock by existing holders
may impair Cayenne's ability to raise capital in the future through the sale of
Cayenne Common Stock or other equity securities.

     Cayenne has registered 11,799,945 shares of Cayenne Common Stock issuable
under its stock option and stock purchase plans, of which 3,071,509 shares were
subject to outstanding options at August 7, 1997. Shares issued upon the
exercise of options and shares issued under Cayenne's stock purchase plan
generally will be eligible for sale in the public market.

LITIGATION

     Cayenne has received correspondence from Esprit Systems Consulting, Inc.
claiming that Cayenne's subsidiary, Cadre Technologies, Inc., is liable to
Esprit for approximately $1,650,000 under an extension to a contract for
services to be rendered to Cadre. Cayenne believes that the claim is without
merit, because, among other things, the contract in question terminated without
extension. The claim has not been asserted formally in arbitration or
litigation, and no assurance can be given as to its future course or likely
result.


                                 USE OF PROCEEDS

     The Company will not receive any proceeds from the sale of Common Stock
offered hereby by the Selling Stockholders.

                    PRICE RANGE OF COMMON STOCK AND DIVIDENDS

     The following table sets forth, for the periods indicated, the range of
high and low sales prices for the Company's common stock, as reported by the
NASDAQ Stock Market. The Company's Common Stock is traded under the NASDAQ
symbol "CAYN" (formerly "BACH") since the Company's initial public offering on
November 26, 1991. These prices reflect interdealer prices, without retail
mark-ups, mark-downs or commissions, and do not necessarily represent actual

     The Company has not declared or paid cash dividends on its common stock and
does not plan to pay cash dividends to its stockholders in the near future. The
Company presently intends to retain any earnings to finance further growth of
its business. At August 7, 1997, there were 617 stockholders of record of the
Company's Common Stock.

NOTE: In October 1996, the Company changed its fiscal year-end from June 30 to
December 31, and accordingly experienced a short fiscal year from July 1 through
December 31, 1996. That short year is referred to as "Fiscal Year 1996b" in the
table above.

                                    BUSINESS

         CAYENNE SOFTWARE, INC., organized as a Massachusetts corporation in
1983 under the name BACHMAN Information Systems, Inc., develops, markets and
supports a comprehensive suite of software products and services. Fortune 1000
companies and government agencies around the world use Cayenne products as they
develop, implement, and maintain enterprise-wide, business-critical information
systems. Cayenne's products are designed around an innovative open architecture
that enables organizations to create applications that integrate diverse
information sources into new high-performance computing environments, to modify
applications as business and technology change, and to run those applications on
a variety of platforms. Cayenne's approach to reusability and its open
architecture directly support mainframe and client/server initiatives and
partnerships with other leading software vendors.

         Cayenne targets its products to Fortune 1000 companies, government
agencies, and organizations of similar size throughout the world that use
personal computers, workstations, mid-range and mainframe computers and
relational database management systems for data-intensive applications.

         The Company develops software tools that help software developers
create applications and integrate diverse information sources for large and
small software development projects. The products include modeling, database
design and development tools for object-oriented, data-driven and structured
application development approaches for use by large corporations, independent
software vendors and technical organizations. The products are targeted to the
object and relational application development needs of software development
teams in a scaleable, workgroup-to-enterprise environment. The Company's
products are used to create real-time and embedded applications, three-tier
client/server applications, data warehouses, and Internet/intranet solutions on
a wide range of platforms. The market in which Cayenne participates is
characterized by frequent and rapid changes in hardware and software technology
and in customer preferences, and therefore, the Company has devoted much effort
to enhance its product offerings and to improve its competitive position
through: development efforts, strategic alliances and acquisitions. These
actions have had an adverse effect on the Company's operating results during
fiscal 1994, 1995 and 1996 the six-month transition period ended December 31,
1996 and the six months ended June 30, 1997.

Cayenne's executive offices, principal research and development facilities, and
principal marketing, customer service and support and production facilities are
located in approximately 62,000 square feet of space in an executive office park
in Burlington, Massachusetts. Cayenne occupies that space under a lease expiring
October 31, 1997. Cayenne is currently negotiating for renewal of its lease.
There is currently substantial demand for general office space in the Greater
Boston area; and Cayenne may experience an increase in rental expense for
periods after October 1997, as well as expenses for moving if Cayenne ultimately
arranges to lease other space. Cayenne maintains its primary sales and support
offices in nine locations in the United States, and its distribution
subsidiaries have offices in Toronto, Canada; Bracknell, England; Wiesbaden and
Munich, Germany; Singapore; Madrid, Spain; Delft, Netherlands; Canberra,
Australia; and Florence, Milan, Rome, and Turin, Italy.


                              SELLING STOCKHOLDERS

         The following table sets forth the number of shares of Common Stock
owned by each of the Selling Stockholders as of August 12, 1997. Except as
indicated, none of the Selling Stockholders has had a material relationship with
the Company within the past three years other than as a result of the ownership
of the Shares


                                      -11-
   15
or other securities of the Company. Because the Selling Stockholders may offer
all or some of the Shares which they hold pursuant to the offering contemplated
by this Prospectus, and because there are currently no agreements, arrangements
or understandings with respect to the sale of any of the Shares, no estimate can
be given as to the amount of Shares that will be held by the Selling
Stockholders after completion of this offering. The Shares offered by this
Prospectus may be offered from time to time by the Selling Stockholders named
below:

(1)      This Registration Statement shall also cover any additional shares of
         Common Stock which become issuable in connection with the shares
         registered for sale hereby by reason of any stock dividend, stock
         split, recapitalization or other similar transaction effected without
         the receipt of consideration which results in an increase in the number
         of the Registrant's outstanding shares of Common Stock.

(2)      Southbrook International Investments, Ltd. holds 100,000 shares of the
         company's Series C Convertible Preferred Stock, which may be converted
         to shares of Common Stock from time to time at a rate determined by the
         lower of the average quoted market price of the Common Stock for either
         (i) the ten trading days preceding the date of issuance or (ii) any
         five trading days during the period of thirty days before the
         conversion. The amount of Common Stock shown in the table reflects the
         amount into which the full 100,000 shares of Preferred Stock might have
         been converted on August 12, 1997 in accordance with the market-price
         formula. Because the number of shares of Common Stock that will be
         ultimately issued to Southbrook upon conversion of the preferred stock
         is dependent upon the conversion formula described above, that amount
         (and therefore the amount of Common Stock offered hereby) cannot be
         determined at this time. Southbrook also holds warrants to purchase an
         aggregate of 233,332 shares of Common Stock. The amount of Common Stock
         shown in the table reflects the amount that the Southbrook would be
         entitled to purchase upon exercise of the warrants in full.


                              PLAN OF DISTRIBUTION

         The Common Stock may be sold from time to time by the Selling
Stockholders, or by pledgees, donees, transferees or other successors in
interest thereof. They may sell from time to time on one or more exchanges, in
the over-the-counter market, or otherwise, at prices and at terms then
prevailing or at prices related to the then current market price or in
negotiated transactions. The shares may be sold by one or more of the following
methods, without limitation: (a) a block trade in which the broker or dealer so
engaged will attempt to sell the shares as agent but may position and resell a
portion of the block as principal to facilitate the transaction, (b) purchases
by a broker or dealer as principal and resale by such broker or dealer for its
account pursuant to the Prospectus, as supplemented, (c) an exchange
distribution in accordance with the rules of such exchange, (d) ordinary
brokerage transactions and transactions in which the broker solicits purchasers,
(e) privately negotiated transactions; if short sales; and (g) a combination of
any such methods of sale. In addition, any securities covered by the Prospectus
which qualify for sale pursuant to Rule 144 may be sold under Rule 144 rather
than pursuant to the Prospectus, as supplemented. From time to time the Selling
Stockholders may engage in short sales, short sales against the box, puts and
calls and other transactions in securities of the Company or derivatives
thereof, and may sell and deliver the shares in connection therewith.

         From time to time Selling Stockholders may pledge their shares pursuant
to the margin provisions of their respective customer agreements with their
respective brokers. Upon a default by a Selling Stockholder, the broker may
offer and sell the pledged shares of Common Stock from time to time.

         To the extent required by applicable law, the specific Shares to be
sold, the names of the Selling Shareholders, the respective purchase prices and
public offering prices, the names of any such agent, broker-dealer or
underwriter, and any applicable commissions or discounts with respect to a
particular offer will be set forth in an accompanying Prospectus Supplement.
Resales or reoffers of the Shares by the Selling Shareholders must be
accompanied by a copy of this Prospectus.

         The Selling Shareholders and any agents, broker-dealers or underwriters
that participate in the distribution of the Shares may be deemed to be
underwriters, and any profit on the sale of the Shares by them, and any
discounts, commissions or concessions received by them, may be deemed to be
underwriting commissions or discounts under the Securities Act.

ITEM 15.  INDEMNIFICATION OF DIRECTORS AND OFFICERS.

      Paragraph D of Article 6 of the Company's Articles provides that, to the
maximum extent permitted by Massachusetts law (as the same exists or is
subsequently amended), no director shall be personally liable to the Company or
any of its stockholders for monetary damages arising out of the director's
breach of fiduciary duty as a director of the Company. Section 13(b)(l 1/2) of
the Massachusetts BCL provides that a Massachusetts corporation's articles of
organization may state a provision eliminating or limiting the personal
liability of a director to a corporation or its stockholders for monetary
damages for breach of fiduciary duty as a director, provided that such provision
may not eliminate or limit the liability of a 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 specified sections of the Massachusetts
BCL establishing the liability of directors for certain unauthorized
distributions and loans to insiders or (iv) for any transaction from which the
director derived an improper personal benefit.

      Section 6 of Article VII of the the Company's By-Laws provides that the
Company shall, to the extent legally permissible, indemnify each of its
directors and officers (including persons who serve at its request as directors,
officers or trustees of any organization in which the Company has an interest as
a stockholder, creditor or otherwise), against all liabilities and expenses
reasonably incurred by such persons in connection with the defense or
disposition of any action, suit or proceeding in which they may be involved or
with which they may be threatened by reason of being or having been such a
director or officer, except with respect to any matter as to which they shall
have been adjudicated not to have acted in good faith in the reasonable belief
that their action was in the best interests of the Company. Section 67 of the
Massachusetts BCL authorizes a Massachusetts corporation to indemnify its
directors, officers, employees and other agents unless such person shall have
been adjudicated in any proceeding not to have acted in good faith in the
reasonable belief that such action was in the best interests of the corporation.

      The effect of these provisions would be to permit indemnification by the
Company for, among other liabilities, (a) liabilities arising out of the
Securities Act in connection with this Registration Statement (see Item 9
below).

      Section 67 of the Massachusetts BCL also affords a Massachusetts
corporation the power to obtain insurance on behalf of its directors, officers,
employees and agents against liabilities incurred by them in those capacities or
out of their status as such, whether or not the corporation would have the power
to indemnify them against those liabilities. The Company has procured
a directors' and officers' liability and company


                                      II-1
   19
reimbursement liability insurance policy that (a) insures directors and officers
of the Company against losses (in excess of a deductible amount) arising from
certain claims made against them by reason of certain acts done or attempted by
such directors or officers and (b) insures the Company against losses (in excess
of a deductible amount) arising from any such claims, but only if the Company is
required or permitted to indemnify such directors or officers for such losses
under statutory or common law or under provisions of the Company's articles of
organization or by-laws.

ITEM 17. UNDERTAKINGS.

         The undersigned Registrant hereby undertakes:

                  (a) To file, during any period in which offers or sales are
                  being made, a post-effective amendment to this Registration
                  Statement:


                  (i) To include any prospectus required by Section 10(a)(3) of
                  the Securities Act of 1933;

                  (ii) To reflect in the prospectus any facts or events arising
                  after the effective date of the Registration Statement (or the
                  most recent post-effective amendment thereof) which,
                  individually or in the aggregate, represent a fundamental
                  change in the information set forth in the Registration
                  Statement;

                                      II-2
   20
                  (iii) To include any material information with respect to the
                  plan of distribution not previously disclosed in the
                  Registration Statement or any material change to such
                  information in the Registration Statement;

         provided, however, that paragraphs 2 (a)(1)(i) and 2 (a)(1)(ii) do not
         apply if the information required to be included in a post-effective
         amendment by those paragraphs is contained in periodic reports filed by
         the Registrant pursuant to Section 13 or Section 15(d) of the
         Securities Exchange Act of 1934 that are incorporated by reference
         herein.

                  (b) That, for the purpose of determining any liability under
                  the Securities Act of 1933, each such post-effective amendment
                  shall be deemed to be a new registration statement relating to
                  the securities offered herein, and the offering of such
                  securities at that time shall be deemed to be the initial bona
                  fide offering thereof.

                  (c) To remove from registration by means of a post-effective
                  amendment any of the securities being registered which remain
                  unsold at the termination of the offering.

         3. Insofar as indemnification for liabilities arising under the
Securities Act of 1933 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 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 Act and will
be governed by the final adjudication of such issue.
