      CERTAIN SELLING STOCKHOLDERS IS NOT EXERCISED;



    - THE CONVERSION OF ALL SHARES OF OUR OUTSTANDING SERIES A, SERIES B AND

                                   BLUESTONE


    We are a leading provider of software for enterprise interaction management,
which enables businesses to extend information over the World Wide Web in a
controlled manner and to support high volumes of users and interactions. Our
flagship product, Sapphire/Web, is a framework for JAVA Web application servers
and is currently in Release 6. A Web application server is a software product
that allows broad access to stored corporate information and applications to a
variety of users, including customers, suppliers and employees via the Web. We
believe that our JAVA Web application server is the leading solution of its kind
based on the breadth of its functionality. We believe that ours is the only
product to adequately address the four defining elements of enterprise
interaction management-- development, deployment, integration and
management--and therefore provides the most complete overall solution to our
customers. In January 1999, we released Bluestone XML-Server, which represents a
new generation of specialized Web application server focused on commerce via the
Internet.


OUR INDUSTRY


    Businesses are rapidly adopting technology that allows their existing
computer systems to operate and be accessed over the Web. To date, most
businesses have simply provided marketing material on their Web sites and have
not been able to take full advantage of the interactive potential of the
Internet. The existing information technology infrastructure of most companies
cannot reliably and securely handle a high volume of interactions across the
Internet. Therefore, most companies are unable to utilize, integrate or deploy
their existing information technology assets for Internet commerce or use over
the Web.



    Deploying Web application servers allows real time, interactive access to
complex information through the Web that is otherwise only available internally
in an organization through its own applications and existing corporate
databases. This enables a much broader and diverse audience to utilize and
interact with a business' core systems and information. Uses of this capability
include:


    - broad dissemination and more effective use of management information for
      decision support;

    - employee self-service applications that improve internal efficiencies;

    - customer relationship management activities that enhance service levels;

    - supply chain functions that increase coordination among trading partners;
      and


    - Internet commerce initiatives that create entirely new revenue streams and
      business models.


    Demand for these capabilities has resulted in significant growth in the
market for Web application servers. In an August 1998 report, Forrester Research
estimated that the market for application server

                                       1
<PAGE>
software would be approximately $700 million in 1999 and grow to approximately
$1.8 billion by 2001, representing a compound annual growth rate of
approximately 60%. Another independent technology research organization, Ovum,
estimated in a June 1999 report that the market for application server
technologies, which Ovum defines in a manner that more closely resembles our
addressable market, will grow to $17 billion by 2004. As this market develops,
businesses are recognizing that a broader set of facilities, beyond simple
deployment alone, are required to capture the substantial benefits that Internet
computing can provide.

OUR SOLUTION


    We provide a comprehensive framework that enables businesses to deploy
information across the Internet to employees, customers, suppliers and partners.
Our solution furnishes businesses with the ability to Web-enable their existing
systems, develop new Web-based applications, integrate their applications and
enable Internet commerce. Our deployment solution is 100% Pure JAVA, a
programming language developed by Sun Microsystems that operates in virtually
all computing environments. We believe our solution is the only one available
that allows organizations to develop, deploy, integrate and manage
enterprise-scale, mission-critical applications. In particular, our solution
offers the following facilities:


    - robust development environment and toolset that is open and highly
      adaptable and has many features that increase the speed and reduce the
      cost of systems development;

    - open, high-performance deployment that enables implementation of systems
      with high reliability, security and flexibility and supports very high
      volumes of interactions;

    - extensive integration capabilities that facilitate the integration of a
      business' overall computing environment; and

    - comprehensive management features that provide the necessary means to
      monitor, administer and report on a business' entire Web infrastructure.

OUR GROWTH STRATEGY


    Our goal is to maintain and extend our position as a leading provider of Web
application server technology, enterprise application integration and Internet
commerce solutions. Our key growth strategies are to:


    - maintain and extend technological leadership;

    - expand product offerings;

    - continue to focus on enterprise-scale solutions;

    - increase marketing and direct sales efforts; and

    - further develop indirect channels, partners and alliances.

OUR CUSTOMERS

    Our solutions are applicable to a wide variety of industries and are used by
many of the world's leading businesses, including:

    - three of the top five FORTUNE 500 companies in the electronics industry;

    - five of the top ten FORTUNE 500 companies in the computer equipment
      industry;

    - four of the top five FORTUNE 500 companies in the aerospace industry;

    - seven out of the top ten FORTUNE 500 companies in the telecommunications
      industry;

                                       2
<PAGE>
    - three of the top four FORTUNE 500 companies in the entertainment industry;
      and

    - five of the top ten FORTUNE 500 companies in the pharmaceuticals industry.


    We market our products and services through our direct sales force and a
network of value added resellers, independent software vendors, and systems
integrators. Since 1996, we have sold our Sapphire/Web software products to over
500 customers. Our customers include ARI, AT&T, Deutsche Bank, Dreyfus
Corporation, Eli Lilly, Hewlett-Packard, Houghton Mifflin Company, Just For
Feet, MCI WorldCom, OpenConnect and Reliance National.

                         SUMMARY FINANCIAL INFORMATION


    The following table sets forth certain of our historical, pro forma and
adjusted financial data. The pro forma balance sheet data presented below
assumes the conversion of all outstanding preferred stock and accrued dividends
on preferred stock into common stock. The pro forma net loss per share amounts
presented below reflect the outstanding preferred stock during each period
presented on an as converted basis. The adjusted balance sheet data presented
below gives effect to the receipt of the net proceeds from the sale of shares of
common stock offered by us at an assumed offering price of $12.00 per share,
after deducting the estimated underwriting discounts and commissions and our
estimated offering expenses.


    In April 1997, in connection with our sale of Series A preferred stock, we
spun off our consulting division to our then sole stockholder. The consulting
division spin-off has been reported as a discontinued operation. In April 1998,
we decided to focus on internally developed software products and curtail the
licensing and services related to third party products. No material license
revenues from third party products were recognized after March 31, 1998.

CAUTION YOU THAT THIS PROSPECTUS INCLUDES FORWARD-LOOKING STATEMENTS THAT ARE

WE HAVE HAD RECENT LOSSES AND  We have incurred significant net losses since 1996,
MAY INCUR FUTURE LOSSES THAT   including losses of approximately $3.8 million and $11.6
MAY DEPRESS OUR STOCK PRICE.   million for the years ended December 31, 1997 and 1998,
                               respectively and $7.5 million for the six months ended
                               June 30, 1999. Our losses have resulted in an accumulated
                               deficit of approximately $26.4 million as of June 30,
                               1999. Any significant shortfall of revenues in relation to
                               our expectations or any material delay of customer orders
                               would have an immediate adverse effect on our business,
                               operating results and financial condition. We may not be
                               profitable in any future period. Our future operating
                               results will depend on many factors, including:

                               -  the overall growth rate for the markets in which we
                                  compete;
                               -  the level of market acceptance of, and demand for, our
                                  software products;
                               -  the level of product and price competition;
                               -  our ability to establish strategic marketing
                               relationships, develop and market new and enhanced
                                  products, and control costs;
                               -  our ability to expand our direct sales force and
                               indirect distribution channels;
                               -  our ability to integrate acquired businesses and
                               product lines;
                               -  our ability to develop and maintain awareness of our
                                  brands; and
                               -  our ability to attract, train and retain consulting,
                                  technical and other key personnel.

LACK OF GROWTH OR DECLINE IN   Our products enhance companies' ability to transact
INTERNET USAGE OR THE LACK OF  business and conduct operations utilizing the Internet.
ACCEPTANCE OF COMMERCE         Therefore, our future sales and any future profits are
CONDUCTED VIA THE INTERNET     substantially dependent upon the widespread acceptance and
COULD BE DETRIMENTAL TO OUR    use of the Internet as an effective medium of commerce by
FUTURE OPERATING RESULTS.      consumers and businesses. Rapid growth in the use of the
                               Internet and other online services is a recent development
                               and we are unsure whether that acceptance and use will
                               continue to develop or that a sufficiently broad base of
                               consumers will adopt and continue to use the Internet and
                               other online services as a medium of commerce. To be
                               successful, we must rely on consumers and businesses, who
                               have historically used traditional means of commerce to
                               purchase products, accepting and utilizing new ways of
                               conducting business and exchanging information over the
                               Internet.

                               In addition, the Internet may not be accepted as a viable
                               commercial marketplace for a number of reasons, including
                               potentially inadequate development of the necessary
                               network infrastructure or delayed development of enabling
                               technologies and Web performance improvements. If the
                               Internet continues to experience significant growth in the
                               number of users, frequency of use or an increase in
                               bandwidth requirements, the Internet's infrastructure may
                               not be able to support the demands placed upon it. In
                               addition, the Internet could lose its viability due to
                               delays in the development or adoption of new standards and
                               protocols required to handle increased levels of Internet
                               activity, or due to increased governmental regulation. If
                               Congress, or other governing bodies both within and
                               outside the United States, decides to alter materially the
                               current approach to, and level of, regulation of the
                               Internet, we may need to adapt our technology. Any
                               required adaptation could cause us to spend significant
                               amounts of time and money. If use of the Internet does not
                               continue to grow or grows more slowly than expected, if
                               the infrastructure for the Internet does not effectively
                               support growth that may occur, if government regulations
                               change, or if the Internet does not become a viable
                               commercial marketplace, our business could suffer.

ADVERSELY AFFECTED.            factor adversely affecting the market for Web application
                               server software in general, or our software in particular,
                               would adversely affect our ability to generate revenues.
                               The market for Web application server software is
                               competitive, highly fragmented and characterized by rapid
                               technological change. Our future financial performance
                               will depend in large part on the successful development,
                               introduction and customer acceptance of our new products
                               and product enhancements in a timely and cost effective
                               manner. After the offering, we expect to commit
                               significant resources to market and further develop the
                               Sapphire/Web software products and enhance the brand

                               correct defects and limitations in its products, our
                               ability to continue to improve and ship our products could
                               be impaired. In the future, our customers may also require
                               the ability to deploy our products on platforms for which
                               technically acceptable JAVA implementations either do not
                               exist or are not available on commercially reasonable
                               terms.

                               In January 1999, we introduced a product based on a
                               document format for the Web called XML, or extensible
                               mark-up language. We cannot be sure that XML technology
                               will be adopted as a standard, that XML-based products
                               will achieve broad market acceptance, that our XML
                               products will be accepted or that other superior
                               technologies will not be developed. The failure of XML
                               technology to become a standard or the failure of our XML
                               products to achieve broad acceptance could adversely
                               affect our ability to generate revenues. The XML server
                               technology is one of several competing technologies used
                               in information exchange and Internet commerce. We intend
                               to continue to invest substantial resources in our XML
                               products.

                               competition in our market. Our competitors consist of a
                               number of private and public companies including, among
                               others: BEA Systems which acquired WebLogic; IBM;
                               Microsoft; Oracle; and Sun Microsystems, which acquired
                               NetDynamics and the rights to Netscape's Application
                               Server. In addition, we face competition from in-house
                               software developers who may develop some or all of the
                               functionality that our products provide. Many of our

                               We expect to face increased competition in the future from
                               our current competitors. In addition, new competitors, or

                               emerge and rapidly gain significant market share. We also
                               may face increased competition from existing large
                               business application software vendors that may broaden

                               software. Their significant installed customer bases and
                               abilities to offer a broad solution and price these new
                               products as incremental add-ons to existing systems could

                               substantial portion of revenues in any given quarter in

                               revenues in each of several quarters. As a result, our

                               or the loss of any one major customer could cause our

                               various functional and geographic areas, each often having
                               specific and conflicting requirements. Accordingly, we

                               result, our ability to forecast the timing and amount of
                               specific sales is limited and the delay or failure to

YEAR 2000 PROBLEMS MAY         Many currently installed computer systems and software
DISRUPT OUR BUSINESS.          products are coded to accept only two digit entries in the
                               date field. Beginning in the year 2000, these date fields
                               will need to accept four digit entries to distinguish
                               twenty-first century dates from twentieth century dates.
                               As a result, over the next several months, computer
                               systems and/or software used by many companies may need to
                               be upgraded to comply with these "Year 2000" requirements.
                               Significant uncertainty exists in the software industry
                               concerning the potential effects associated with
                               compliance. While our software products are not time/date
                               sensitive, many of the third party software applications
                               run by our customers are time/date sensitive. In addition,
                               we have in the past resold third party software that may
                               not be Year 2000 compliant.

                               We may experience unanticipated problems and costs caused
                               by undetected errors or defects in the software used in
                               our internal systems related to the Year 2000 transition.
                               If our internal computer systems are not Year 2000
                               compliant then we or our customers may suffer system
                               failures or miscalculations that could cause disruptions
                               of operations.

                               In addition, we believe that the purchasing patterns of
                               customers and potential customers may be affected by Year
                               2000 issues in a variety of ways. Many companies are
                               expending significant resources to correct or patch their
                               current software systems for Year 2000 compliance. These
                               expenditures may result in reduced funds available to
                               purchase software products such as those offered by us.

                               Our reasonable worst case scenarios include:

                               -  exposure to potential business disruption and resulting
                                  claims, whether with or without merit;
                               -  temporary inability to process transactions internally,
                               to send invoices to vendors and customers or to engage in
                                  similar normal business activities; and
                               -  postponed or delayed sales because existing and
                               potential customers may choose to defer purchasing, or

                                  such as those offered by us.

                               offset these and other business risks related to the Year

PRICE.                         perception that those sales may occur. These sales could
                               also make it more difficult for us to raise funds through
                               equity offerings in the future at a time and at a price
                               that we think is appropriate.

                               After completion of this offering, the current holders of
                               most of our common stock and all of our preferred stock
                               outstanding prior to this offering, as well as the holders
                               of outstanding warrants, will be entitled to registration
                               rights with respect to their common stock or the common
                               stock underlying their convertible securities. If these
                               holders, by exercising their registration rights, cause a
                               large number of securities to be registered and sold in
                               the public market, these sales could have an adverse
                               effect on the market price for our common stock. If we
                               were to include, in a registration statement initiated by
                               us, shares held by these holders pursuant to the exercise
                               of their registration rights, these sales may have an
                               adverse effect on our ability to raise needed capital.

                           FORWARD-LOOKING STATEMENTS


    Some statements in this prospectus constitute forward-looking statements.
Forward-looking statements involve known and unknown risks, uncertainties and
other factors which may cause our actual results, performance or achievements or
industry results to be materially different from any future results, performance
or achievements expressed or implied by these forward-looking statements. Such
factors include those described in "Risk Factors." The forward-looking
statements included in this prospectus may prove to be inaccurate. In light of
the significant uncertainties inherent in these forward-looking statements, you

that our objectives and plans will be achieved.


                                USE OF PROCEEDS


    The net proceeds to us from the sale of 4,000,000 shares of common stock, at
an assumed initial public offering price of $12.00 per share, will be
approximately $43.8 million, or $47.2 million if the underwriters'
over-allotment option is exercised in full, after deducting underwriting
discounts and commissions and estimated offering expenses payable by us. While
we have not determined the specific allocation of the net proceeds of this
offering, we currently intend to use the net proceeds for product development,
sales and marketing and working capital.



    Pending their application as described above, we intend to invest the net
proceeds in short-term, investment-grade, interest-bearing securities.


                                DIVIDEND POLICY


    We intend to retain any future earnings to support operations and to finance
the growth and development of our business, and we do not anticipate paying cash
dividends for the foreseeable future. Under our current credit facility, we are
prohibited from paying dividends except those accruing to outstanding preferred
stock. As of June 30, 1999, there were $1.7 million in accrued dividends on our
convertible preferred stock. Upon the conversion of the preferred stock into
common stock, we are required to pay to the holders of the preferred stock being
converted all accumulated and unpaid cash dividends, whether or not declared,
with respect to the preferred stock. However, if requested by any holder of the
shares of preferred stock being converted and approved by the holders of a
majority of the then outstanding shares of common stock, the holder may exchange
all or any portion of the accumulated and unpaid cash dividends into shares of
common stock at the then fair market value of the common stock.

                                    DILUTION


    Our pro forma net tangible book value as of June 30, 1999 was $16.3 million
or $1.22 per share of common stock. We determined our pro forma net tangible
book value per share by subtracting our total liabilities from our total
tangible assets and dividing that number by 13,302,473 pro forma shares of
common stock outstanding as of June 30, 1999. The pro forma information provided
immediately above and in the two tables below gives effect to:



    - the conversion of all outstanding shares of preferred stock into common
      stock; and



    - the assumed conversion of accrued dividends on preferred stock into common
      stock.



    Dilution in net tangible book value per share represents the difference
between the amount per share paid by purchasers of shares of our common stock in
this offering and the net tangible book value per share of our common stock
immediately following this offering. Assuming an initial offering price of
$12.00 per share after giving effect to our sale of shares of common stock in
this offering and after deducting the estimated underwriting discount and
commissions and our estimated offering expenses, our pro forma net tangible book
value as of June 30, 1999 would have been $60.1 million or $3.47 per share of
common stock. This represents an immediate increase in net tangible book value
of $2.25 per share to existing stockholders and an immediate dilution of $8.53
per share to new investors. The following table illustrates this per share
dilution:

    The following table summarizes on a pro forma basis as of June 30, 1999 the

the number of shares of common stock purchased from us, the total consideration

    - 2,663,589 shares of common stock issuable upon the exercise of outstanding
      stock options granted as of June 30, 1999 under our option plan with a
      weighted average exercise price of $4.01 per share and 275,534 shares
      reserved for issuance under the option plan;



    - 156,250 shares reserved for issuance under our director compensation plan;

      issued to certain holders of the preferred stock with a weighted average

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

GENERAL


    We were incorporated in New Jersey in 1989 as Bluestone Consulting, Inc. Our
primary business initially consisted of general information technology
consulting on the UNIX platform and information technology staffing. In January
1991, we entered the software business and became a value added reseller of
third party software products. We also began to develop software internally for
sale to customers as part of our software business. In October 1995, our
proprietary product, Sapphire/Web 1.0, was released.



    In March 1997, we reincorporated in Delaware and changed our name to
"Bluestone Software, Inc." In April 1997, we spun off our consulting business to
Bluestone Consulting, Inc. a newly formed Delaware corporation ("BCI").
Immediately after the spin-off, our business consisted of two product lines:



    - Sapphire/Web, our proprietary software product; and



    - third party graphical user interface software products, which we resold to
      our customers.


    For the year ended December 31, 1997, the Sapphire/Web products and related
services generated approximately $4.5 million in revenues, while third party
products and related services contributed approximately $5.2 million.


    In 1998, we decided to focus on internally developed software products and
curtail the licensing and services related to third party products. Beginning in
March 1998, we increased our sales and marketing efforts and hired new
management. We hired a significant number of sales personnel throughout the
country in order to develop a nationwide presence and generate increased
revenue. The positioning and feature set of the Sapphire/Web product was shifted
from a low-cost development tool to an enterprise-wide software solution for
Internet applications. For the year ended December 31, 1998, the Sapphire/Web
products and related services generated approximately $7.0 million in revenues,
while third party products and related services contributed approximately $1.1
million. In January 1999, we released Bluestone XML-Server, which represents a
new generation of specialized Web application server focused on Internet
commerce. In May 1999, Release 6 of Sapphire/Web was made generally available.


OVERVIEW

    Our fiscal year end is December 31. References to 1996, 1997 or 1998 mean
the fiscal year ended December 31 unless otherwise indicated.


    We generate revenue from two principal sources:



    - license fees for our software products; and



    - professional services and support revenue derived from consulting,
      training and maintenance services related to our software products.



    In 1998, one customer accounted for 11% of our total product and services
revenues and in the six months ended June 30, 1999, one customer accounted for
29% of our total product and services revenues. Our top 10 customers represented
34%, 39% and 66% of total revenues in 1997, 1998 and in the six months ended
June 30, 1999, respectively.


    SOFTWARE LICENSE FEES.  Typically, our customers pay an up-front, one-time
fee for a perpetual license of our software. The amount of the fee is based on
the number of developer seats and server interactions. A pricing model based on
the number of processors within a server is also available. We also sell annual
and multi-year licenses, primarily to independent software vendors. We generally
require a written license contract that typically provides for an initial
payment within 30-60 days of contract signing. Certain multi-year license
contracts contain payment terms that extend beyond one

                                       20
<PAGE>
year. Pursuant to the American Institute of Certified Public Accountants'
Statement of Position 97-2, any amounts due under contract beyond one year are
not deemed to be fixed and determinable and therefore are deferred and
recognized as revenue when the payments become due.


    Prior to 1998, software licenses were principally the result of direct sales
to end-users. Beginning in 1998, we began to focus on channel marketing. This
has resulted in significant sales of products sold through independent software
vendors, resellers and systems integrators. We believe that these alliances have
helped to maximize our exposure in the marketplace. Furthermore, we have
experienced, and expect to continue to experience, significant variation in the
size of individual licensing transactions, ranging from small sales of perpetual
developer licenses to large, multi-year licensing arrangements with independent
software vendors.


    We generally recognize license fee revenue when a formal agreement exists,
delivery of the product has occurred, no production, modification, customization
or implementation obligations remain, the license fee is deemed fixed and
determinable and collectibility is probable. Revenue from arrangements with
distributors and resellers is not recognized until our product is delivered to
the end-user.


    SERVICES REVENUE.  Services revenue consists principally of revenue derived
from consulting services provided to customers during implementation and
integration of our software products, training of customers' employees and fees
for ongoing maintenance, which consists of customer technical support services
and unspecified product upgrades/enhancements on a when-and-if-available basis.
Consulting and training services are typically delivered on a time and material
basis and are typically completed within one month following license contract
signing. Consulting services generally consist of simple installations and
configurations. We recognize services revenue as the services are performed.
Maintenance revenue is generally invoiced in advance and is recognized ratably
over the term of the maintenance agreement, which is generally 12 months.


    COST OF SOFTWARE LICENSE FEES.  Cost of software license fees consists
primarily of the costs associated with the purchase of product CDs and related
documentation and duplication costs.

    COST OF SERVICES.  Cost of services consist primarily of salary and benefit
costs of our consulting, support and training organizations, and are expensed
when incurred. Additionally, from time to time we engage outside consultants to
meet peaks in customer demand.

    SALES AND MARKETING.  We license our products primarily through our indirect
channels and direct sales force. Sales and marketing expenses consist primarily
of personnel costs, commissions to employees, office facilities, travel and
promotional events such as trade shows, advertising and public relations
programs.

    PRODUCT DEVELOPMENT.  We maintain an in-house development staff to enhance
our existing products and to develop new ones. Product development expenditures
are generally charged to operations as incurred. Statement of Financial
Accounting Standards No. 86 requires the capitalization of certain software
development costs subsequent to the establishment of technological feasibility.
We establish technological feasibility upon the completion of a working model.
To date, we have expensed all software development costs due to the minimal
level of development costs incurred subsequent to the establishment of
technological feasibility.

    GENERAL AND ADMINISTRATIVE.  General and administrative expenses include our
personnel and other costs of our finance, human resources and information
services activities.

    STOCK BASED COMPENSATION.  The amount by which the fair market value of our
common stock exceeded the exercise price of stock options on the date of grant
is recorded as deferred compensation and is amortized to stock based
compensation expense as the options vest.

</TABLE>



SIX MONTHS ENDED JUNE 30, 1999 COMPARED TO SIX MONTHS ENDED JUNE 30, 1998


SOFTWARE LICENSE FEES


    Sapphire/Web license fees were $4.7 million and $1.2 million for the six
months ended June 30, 1999 and 1998, respectively. This increase of 296.6% was
primarily due to a shift in our product position from a low-priced development
tool to a high-end, high-priced enterprise software solution. This change in
product position has resulted in increased revenues per customer. Additionally,
we were able to concentrate solely on our Sapphire/Web products and services
once we curtailed our graphical user interface product line in April 1998. In
addition, we received payment under an extended license fee arrangement with one
customer in February 1999, which accounted for approximately $1.9 million of our
license fee revenue during the six months ended June 30, 1999.


SERVICES REVENUE


    Sapphire/Web services revenue was $1.9 million and $1.7 million for the six
months ended June 30, 1999 and 1998, respectively, an increase of 9.3%. Services
revenue remained relatively constant between the two periods due to a strategic
change in the use of our professional staff. By the beginning of 1999, the main
focus of the services organization had shifted to concentrate on short-term,
installation-type engagements, usually 2-3 days in duration, rather than
long-term implementation activities. These implementation activities are now
performed primarily by systems integrators with which we have strategic
alliances.

THIRD PARTY PRODUCTS AND RELATED SERVICES REVENUE


    Third party products and related services revenue was zero and $932,000 for
the six months ended June 30, 1999 and 1998, respectively. This decrease was due
to our decision in 1998 to curtail the licensing and services related to third
party products so that we could focus on our proprietary products.


GROSS MARGIN--LICENSE FEES


    Our license fee gross margin increased to 96.7% for the six months ended
June 30, 1999 from 91.9% for the same period in 1998. This increase was
primarily due to the increase in revenue per customer. Our focus on positioning
the product as an enterprise-wide solution has increased the revenue associated
with each sale, while the cost of sales for the product has remained relatively
constant.


GROSS MARGIN--SERVICES REVENUE


    Our services gross margin decreased to (32.3)% for the six months ended June
30, 1999 from (21.8)% for the same period in 1998. This was primarily due to the
hiring and training of additional services personnel in advance of anticipated
services revenue growth.


SALES AND MARKETING


    Sales and marketing expenses were $6.2 million and $3.7 million for the six
months ended June 30, 1999 and 1998, respectively, an increase of 65.0%. Of this
increase, $1.1 million was due to increases in payroll and related costs,
recruiting costs and travel costs as a result of the growth in the number of
sales personnel, $600,000 was due to increased advertising and trade show
expenses, and $256,000 was due to increased commissions expense as a result of
higher sales volume. We have increased our spending on sales and marketing
because we believe that our sales and marketing efforts are essential for us to
increase our market position and our product acceptance. The average number of
sales and marketing employees for the six months ended June 30, 1999 was 54
compared to 42 for the six months ended June 30, 1998. We also incurred
increases in variable marketing expenses due to increased trade show
participation, direct mail campaigns and advertising in order to increase market
awareness and gain market acceptance of our products. These costs as a
percentage of revenue were 93.8% and 97.8% for the six months ended June 30,
1999 and 1998, respectively.


PRODUCT DEVELOPMENT


    Product development expenses were $1.9 million and $904,000 for the six
months ended June 30, 1999 and 1998, respectively, an increase of 106.3%. These
costs as a percentage of revenue were 28.3% and 23.6% for the six months ended
June 30, 1999 and 1998, respectively. These increases were associated with the
development of our new products, Sapphire/Web Release 6 and the Bluestone XML
Suite. We believe that our product development investment is essential for us to
maintain our market and technological competitiveness. Average development
headcount for the six months ended June 30, 1999 and 1998 was 30 and 22,
respectively.



GENERAL AND ADMINISTRATIVE



    General and administrative expenses were $2.1 million and $950,000 for the
six months ended June 30, 1999 and 1998, respectively. Included in expenses for
the six months ended June 30, 1999 were $604,000 for severance and consulting
costs. The severance costs were related to the termination of certain
executives, and the consulting costs were based upon the fair value of options
issued to outside consultants. Excluding these costs, our general and
administrative expenses were $1.5 million, an increase of 62.8% over the six
months ended June 30, 1998. This increase was primarily due to payroll and
related costs resulting from the addition of personnel to support the growth of
our business. General and administrative expenses as a percentage of revenue
were 32.6% and 24.8% for the six


                                       23
<PAGE>

months ended June 30, 1999 and 1998, respectively. Excluding these severance and
consulting costs, the expenses as a percentage of revenue decreased to 23.5%.



AMORTIZATION OF STOCK-BASED COMPENSATION



    Amortization of stock-based compensation was $112,000 and zero for the six
months ended June 30, 1999 and 1998, respectively. Deferred compensation of $1.4
million arose due to the issuance of stock options at exercise prices below the
fair market value of our common stock for accounting purposes relative to the
hiring of key employees and directors during the three months ended June 30,
1999. Deferred compensation is included as a component of stockholders' equity
and is being amortized by charges to operations over the vesting periods of the
options. As of June 30, 1999, we had an aggregate of $1.3 million of deferred
compensation to be amortized through June 30, 2003.



INTEREST EXPENSE



    Net interest expense was $1.1 million and $34,000 for the six months ended
June 30, 1999 and 1998, respectively. This increase was due to the issuance of
warrants to purchase 137,608 shares of common stock at the weighted exercise
price of $2.06 per share in connection with the issuance of convertible
subordinated bridge notes. Original issue discount interest cost of $1.1 million
was recorded during the three months ended June 30, 1999 based upon the fair
value of the warrants at the dates of issuance. The warrants are recorded as a
component of stockholders' equity.


1998 COMPARED TO 1997

SOFTWARE LICENSE FEES

    Sapphire/Web license fees were $3.4 million and $2.3 million for 1998 and
1997, respectively. The increase of 45.1% was due to increased market acceptance
of the Sapphire/Web software suite.

SERVICES REVENUE

    Sapphire/Web services revenue was $3.6 million and $2.2 million for 1998 and
1997, respectively. This increase of 66.1% was due to the increase in the number
of consulting and training engagements associated with our growing customer
base.

THIRD PARTY PRODUCTS AND RELATED SERVICES REVENUE

    Third party products and related services revenue was $1.1 million and $5.2
million for 1998 and 1997, respectively. This decrease was due to our decision

relatively constant.

GROSS MARGIN--SERVICES REVENUE

    Our services gross margin decreased to (22.5)% in 1998 from (15.5)% in 1997.
This decrease in the gross margin was primarily due to the hiring and training
of additional personnel to support our growing installed base of customers and
anticipated increase in future revenues.

SALES AND MARKETING


    Sales and marketing expenses were $9.6 million and $5.1 million in 1998 and
1997, respectively, an increase of 86.1%. These costs as a percentage of revenue
increased to 117.7% in 1998 from 52.7% in 1997. These increases were primarily
due to an increase in the number of sales and marketing personnel between March
and September 1998, including the addition of a new Senior Vice President, Sales
and a Senior Vice President, Marketing, as well as three Sales Vice Presidents.
In 1998, we


                                       24
<PAGE>
opened seven new remote sales offices in Georgia, California, Texas, Colorado
and Illinois. Beginning in March 1998, we focused our marketing efforts on
achieving market awareness of Bluestone and acceptance of our products, and
subsequently incurred significant costs for trade show participation,
advertising and direct mail campaigns.

PRODUCT DEVELOPMENT


    Product development expenses were $2.5 million and $1.3 million for 1998 and
1997, respectively, an increase of 91.0%. These costs as a percentage of revenue
increased to 30.5% in 1998 from 13.3% in 1997. These increases were primarily
due to an increase of $948,000 in payroll and related costs related to the
hiring of additional developers, and $115,000 for additional rent and
depreciation expense related to capital expenditures for software, hardware and
equipment.


GENERAL AND ADMINISTRATIVE


    General and administrative expenses were $2.3 million and $1.6 million for
1998 and 1997, respectively. This increase of 43.3% was primarily due to
increases in staff to support our growth. These costs as a percentage of revenue
increased to 28.5% in 1998 from 16.6% in 1997.

our growing customer base.

THIRD PARTY PRODUCTS AND RELATED SERVICES REVENUE

    Third party products and related services revenue was $5.2 million and $6.6
million for 1997 and 1996, respectively. This decrease was due to a shift in our
attention from third party products and services towards proprietary products

relatively constant.

began to offer our maintenance services in 1996.

SALES AND MARKETING

    Our comparisons of operating results from 1996 to 1997 and from 1997 to
1998, and for the six months ended June 30, 1998 to the six months ended June
30, 1999, generally apply to the comparison of the results of operations for the
nine quarters in the period ended June 30, 1999. Our third party products and
related services revenue decreased during the four quarters of 1998 due to our
decision to curtail the licensing of third party products so that we could focus
our resources on our proprietary products. Our gross profit margin increased
over the three quarters ended June 30, 1999 due to the increase in our
proprietary software license revenue. The increase in general and administrative
expenses for the three months ended June 30, 1999 resulted primarily from
$577,000 of severance and consulting costs. Net interest expense increased
during the three months ended June 30, 1999 due to the issuance of warrants with
an original issue discount interest cost of $1.1 million in connection with the
issuance of convertible bridge notes. See "Certain Transaction--Bridge
Financing."


    Our quarterly operating results have varied in the past and may vary
significantly in the future depending on many factors including, among others:

    - the size, timing and recognition of revenue from significant orders;

    - increases in operating expenses required for product development and
      marketing;

    - the timing and market acceptance of new products and product enhancements;

    - customer budget constraints;

    - our success in expanding our sales and marketing programs; and

    - general economic conditions.


    We believe that the purchase of our products is relatively discretionary and
generally involves a significant commitment of capital. As a result, purchases
of our products may be deferred or canceled in the event of a downturn in any
potential customer's business or the economy in general. Accordingly, we believe
that, while the quarterly period-to-period comparisons furnish important
information about our revenues and expenses, they are not necessarily meaningful
and should not be relied upon as indicators of future performance.


LIQUIDITY AND CAPITAL RESOURCES


    From our incorporation in 1989 through 1996, we primarily financed our
operations and met our capital expenditure requirements through funds generated
from operations and funds borrowed from lending institutions. From April 1997
through May 1999, we raised approximately $41.6 million of venture capital
funding in order to expand the sales and marketing and product development
efforts of the business. As of June 30, 1999 our primary sources of liquidity
consisted of cash in excess of $20.6 million and $1.0 million of available
borrowings under our $1.75 million revolving line of credit, which is secured by
substantially all of our assets. As of June 30, 1999, the balance outstanding on
our line of credit was $671,000. Borrowings under the line of credit are subject
to a borrowing base of 80% of eligible accounts receivable. Interest on our line
of credit is payable monthly at rates of prime plus .75%. We believe that our
existing capital resources are sufficient to meet our capital requirements for
the next 12 months.



    Net cash used for operating activities was $3.0 million in 1997, $10.3
million in 1998 and $4.7 million for the six months ended June 30, 1999. The
cash used for operating activities was attributable primarily to net losses of
$3.8 million, $11.6 million and $7.5 million in 1997, 1998 and the six months
ended June 30, 1999, respectively.



    Net cash used in investing activities was $872,000 in 1997, $1.2 million in
1998 and $164,000 for the six months ended June 30, 1999. The cash used in
investing activities related primarily to purchases of computers and software
for internal use.


                                       27
<PAGE>

    Net cash provided by financing activities amounted to $5.1 million in 1997,
$11.7 million in 1998 and $23.0 million for the six months ended June 30, 1999.
In 1997, $4.8 million was provided from the sale of Series A preferred stock to
certain venture capital investors, $920,000 was provided from borrowings under
the available credit lines and $250,000 was provided from borrowings from a
related party. In April 1998, approximately $11.2 million was provided from the
sale of Series B preferred stock to certain venture capital investors. In May
1999, we sold 9,191,176 shares of Series C preferred stock for gross proceeds of
$25.0 million, $1.35 million of which was comprised of the conversion of
indebtedness under bridge financing incurred earlier in 1999. For more
information on the bridge financing, see "Certain Transactions--Bridge
Financing."


YEAR 2000 ISSUES

    GENERAL.  Year 2000 issues relate to computer programs or hardware that have
date-sensitive software or embedded chips that may recognize a date using "00"
as the year 1900 rather than the year 2000. This could result in a system
failure or miscalculation causing disruption of operations, including, among
other things, a temporary inability to process transactions, send invoices or
engage in other normal business activities.

    The term "computer programs and hardware" includes accounting, data
processing and telephone/ PBX systems, in addition to other miscellaneous
systems. These systems may contain imbedded technology, which complicates our
identification, assessment, remediation and testing efforts.

    STATE OF READINESS.  We have designed the current versions of our software
products to be Year 2000 compliant, and do not anticipate any Year 2000 issues
related to these products. However, some older versions of our software products
that we no longer sell may not be Year 2000 compliant. Any customer using an
older version of one of our products that is not Year 2000 compliant may need to
upgrade to a newer, compatible version or discontinue using the software prior
to January 1, 2000.


    We have performed an assessment of the Year 2000 readiness of our
information technology systems, including the hardware and software we use to
provide and deliver our products. Our testing to date has included our major
infrastructure items, hardware platforms, telephone, voice mail and operating
systems. All of the tested systems are compliant. Desktop computing, servers,
switching and routing platforms have been inventoried and tested with only minor
upgrades necessary to one router family. All personal computer systems have been
tested and, where necessary, upgraded. By July 1999, we had largely completed
the implementation of Year 2000 compliant internal computer applications for our
main financial and order processing systems.



    We completed a Year 2000 simulation on our internal systems and software
during the first quarter of 1999. Any discrepancies noted were corrected.
Another testing cycle will be completed during the third quarter of 1999 to
ensure that systems then not compliant or systems that are newly discovered to
be non-compliant are remedied. No information technology projects have been
delayed or deferred by our Year 2000 compliance program.



    As of January 1999, all third party vendors who provide us with systems or
software were contacted and provided us with written assurances of their
product's compliance. We have incorporated any recommended changes and upgrades
wherever necessary. We have not used any independent verification or validation
processes to verify the Year 2000 compliance of our third party vendors. In the
event that one or more of our significant vendors or service providers are not
Year 2000 compliant, due to undetected or embedded system components or
technology, we believe that our results of operations will not be materially
adversely affected and that our relationships with customers, vendors and others
will not be materially adversely affected.



    We have also sought assurances of Year 2000 compliance from our material
providers of items other than information technology. To date we have received
approximately 95% of the necessary


                                       28
<PAGE>

responses and will complete this portion of our investigations by the end of the
third quarter 1999. We have not received notification from any vendor indicating
that they are not Year 2000 compliant.



    COST AND RISK.  We have funded our Year 2000 compliance efforts from our
cash flow from operations and we have not incurred any significant costs to date
related to Year 2000 issues and do not expect the cost of future Year 2000
issues to be material. Furthermore, we believe that Year 2000 issues will not
pose significant operational problems for us.



    However, if all Year 2000 issues are not properly identified or if Year 2000
issues that are identified are not assessed, remediated and tested in a timely
fashion, the Year 2000 issue may adversely impact our results of operations or
adversely affect our relationships with customers, vendors or others. Also, we
may experience operational difficulties caused by undetected errors or defects
in embedded technologies that we use in our internal systems. Additionally, we
cannot predict whether the Year 2000 issues of third parties will have a
material adverse impact on our systems or results of operations.



    The costs and completion dates of our Year 2000 identification, assessment,
remediation and testing efforts are based upon management's best estimates,
which were derived using numerous assumptions regarding future events. We have
not used any independent verification or validation process to assure the
reliability of our risks and costs estimates. These estimates may prove to be
inaccurate and actual results could differ materially from those currently
anticipated. Specific factors that could cause these material differences
include, but are not limited to, the ability to identify, assess, remediate and
test all relevant products and services purchased from or by third parties and
other similar uncertainties. In addition, variability of definitions of
"compliance with Year 2000," and the myriad of different products and services
and combinations thereof, used by our customers in connection with our products
may lead to claims against us which we cannot currently estimate. The aggregate
cost of defending and resolving such claims, if any, may adversely impact our
results of operations.


    Year 2000 issues may affect the purchasing patterns of current and potential
customers in a variety of ways. Many companies are expending significant
resources to replace or remedy their current hardware and software systems for
Year 2000 compliance. These expenditures may result in reduced funds available
to purchase software products such as those offered by us. Furthermore, our
customers could be forced to postpone installations of our products due to
dedication of resources to their own Year 2000 issues. We do not believe that
there is any practical way to ascertain the extent of, and have no plan to
address problems associated with, any reduction in purchasing resources of our
customers. Any resulting reduction could have a material adverse effect on our
business.


    To date, there has been no material negative impact on our financial
condition or operations as a result of our Year 2000 compliance program.



    CONTINGENCIES.  We have not yet completed an analysis of the operational
problems and costs, including loss of revenues, that would be reasonably likely
to result from our failure and the failure of certain third parties to complete
efforts necessary to achieve Year 2000 compliance on a timely basis. We plan to
identify the most likely worst case scenario and, if a contingency plan is
required, finalize our plan by September 1999.


                                       29

QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

    We develop our products in the U.S. and have sold them primarily in North
America. As a result, our financial results have not been affected by factors
such as changes in foreign currency exchange rates or weak economic conditions
in foreign markets. In the future, we expect to increase our international
operations which could increase our exposure to these factors.

    Our future interest income will be sensitive to changes in the general level
of U.S. interest rates. However, we plan to invest our excess cash in
short-term, investment-grade, interest-bearing securities and we have concluded
that there is no material market risk exposure relating to these investments.

                                    BUSINESS

OUR COMPANY


    We are a leading provider of software for enterprise interaction management,
which enables businesses to extend information over the Web in a controlled
manner and to support high volumes of users and interactions. Our flagship
product, Sapphire/Web, is a framework for JAVA Web application servers and is
currently in Release 6. A Web application server is a software product that
allows broad access to stored corporate information and applications to a
variety of users, including customers, suppliers and employees, via the Web. We
believe that our JAVA Web application server is the leading solution of its kind
based on the breadth of its functionality. We believe that ours is the only
product to adequately address the four defining elements of enterprise
interaction management--development, deployment, integration and management--and
therefore provides the most complete overall solution to our customers. In
December 1998 at the Giga Information Group's Emerging Technology Conference, we
demonstrated that our solution can meet the needs of virtually any enterprise by
conducting a live simulation of an Internet commerce site running at a rate of
over 100 million interactions per day. In January 1999, we released Bluestone
XML-Server, which represents a new generation of specialized Web application
server focused on commerce via the Internet.


    We participate in the following three separate markets:


    - THE MARKET FOR JAVA WEB APPLICATION SERVERS. In this market sector,
      enterprises employ our solutions to deploy their existing information
      technology assets for use in a Web environment, and to create new
      enterprise applications that are used via the Web.



    - THE MARKET FOR eXTENDING THE SUPPLY CHAIN. In this market sector, our
      products enable the "virtual corporation," which means they allow an
      enterprise to integrate its information assets with those of its partners,
      vendors and customers to improve collaboration utilizing Web technology in
      a highly secure and scalable environment.



    - THE MARKET FOR ENTERPRISE APPLICATION INTEGRATION. In this market sector,
      our products facilitate the integration of disparate computer systems
      within an enterprise. We believe we are particularly well positioned in
      this market, since the necessary capabilities, including standardizing
      corporate data formats and providing access to existing information
      systems, are two of the core strengths of our JAVA Web application server
      software.



    Our solutions are used by some of the world's leading companies, including
ARI, AT&T, Deutsche Bank, Dreyfus Corporation, Eli Lilly, Hewlett-Packard,
Houghton Mifflin Company, Just For Feet, MCI WorldCom, OpenConnect and Reliance
National.


OUR INDUSTRY

    GROWTH IN INTERNET RELATED SOFTWARE


    The Internet has experienced dramatic growth, both in terms of the number of
users and as a means of conducting commercial transactions, and is expected to
continue to grow rapidly. According to a report prepared by the Computer
Industry Almanac Inc., the number of Internet users was over 150 million in
1998, and is expected to grow to over 720 million by the end of 2005.



    The increase of users and business activities on the Web has created a large
and growing market for Web application software as existing businesses and new
Web-based enterprises foster new revenue streams, significantly broaden
information deployment, enable inter-enterprise collaboration and strive to
reduce the cost of maintaining an ever-changing technology infrastructure. An
International Data Corporation report estimates that Internet-centric software,
which accounted for $4.0 billion in revenue in 1997, will approach $16.0 billion
by 2000 due to aggressive corporate adoption.


                                       31

    THE RISE OF THE ENTERPRISE APPLICATION SERVER


    To date, most companies' use of Internet technology has consisted of
employing Internet software products called Web servers to provide marketing
material through their Web sites. This technology allows the presentation of
relatively simple information to users, such as pictures and text, through
static documents. This static information must be preformatted with the
information to be displayed, then manually changed when information is to be
updated. This technology is still heavily in use today, but cannot sufficiently
meet the quickly growing needs of companies to provide complex and dynamic
information to their users. The existing information technology infrastructure
of most companies leaves them unable to utilize, integrate or deploy existing
information technology assets for Internet commerce or use over the Web. These
companies are recognizing that a broader set of facilities is required to
capture the substantial benefits offered by Internet computing. These facilities
include development capabilities that are specifically geared to a Web-based
environment, interaction environments that are scalable and reliable,
integration faculties that allow seamless linkages between the Internet and an
enterprise's existing information infrastructure, and the ability to effectively
monitor and manage Web-based applications and infrastructure. Web application
servers such as our software have emerged to provide these facilities.



    Web application servers, by design, allow scalable, secure real time,
interactive access to complex information through the Web that is otherwise only
available internally in an organization through its own applications and
existing databases. They do this by providing the following capabilities:


    - load balancing--spreading the workload across multiple processors;

    - transaction management--tracking and assuring the completion of
      transactions;

    - integration to multiple back-end sources--making all enterprise
      information available for use;

    - an integrated development environment--a graphical tool to assist software
      developers;

    - application management--monitoring and reporting on all application server
      activity; and

    - multiple user support--the ability to individually serve a community of
      disparate users.

    Demand for these capabilities has resulted in significant growth in the
market for Web application servers. In an August 1998 report, Forrester Research
estimated that the market for Application Server software would be approximately
$700 million in 1999 and would grow to approximately $1.8 billion by 2001,
representing a compound annual growth rate of approximately 60%. Another
independent technology research organization, Ovum, estimated in June 1999 that
the market for application server technologies, which they define in a manner
that more closely resembles our addressable market, will grow to $17 billion by
2004.

OUR SOLUTION


    We provide a comprehensive framework that enables businesses to deploy
information across the Internet, or their proprietary company networks called
intranets and extranets, to employees, customers, suppliers and partners. Our
solution furnishes businesses with the ability to Web-enable existing
information systems, develop new Web-based applications, and enable Internet
commerce. Our deployment solution is certified by Sun Microsystems as 100% Pure
JAVA and therefore operates in all enterprise computing environments. We have
recently introduced the capability to support Hot Swapping, which enables the
movement of applications from one computer to another, and Hot Versioning, which
enables software programs to be updated between user clicks. These features
allow businesses to upgrade or fix their hardware and software without
interrupting user interactions permitting true 24x7 operations. This is
particularly critical for companies engaged in Internet commerce where down time
can be very costly. We believe our solution is the only one available that


                                       32
<PAGE>
provides the features and capabilities necessary for use in enterprise-scale,
mission-critical applications. In particular, our solution offers the following
facilities:


    ROBUST DEVELOPMENT ENVIRONMENT AND TOOLSET.  Our solution includes an
integrated development environment, which can be thought of as a programmer's
toolkit, that uses industry-standard programming components to easily assemble
applications and provides improved support for users with varying skill levels.
This toolkit includes automated routines to generate user interfaces and the
ability to import existing user interfaces from other sources, which increases a
programming staff's development speed. The environment is open and highly
adaptable, which allows programmers to increase their productivity by selecting
the most appropriate tools for a given task.



    SCALABLE, OPEN, HIGH-PERFORMANCE DEPLOYMENT.  The Web application server
framework within our solution enables businesses to make their information
available with a high degree of reliability, security and flexibility. Our Web
application server supports very high volumes of interactions and high numbers
of concurrent users with caching, load balancing and fault-tolerance features,
which optimize response times and ensure the integrity of applications. In
addition, our standards-based, 100% Pure JAVA architecture allows for a high
level of flexibility in operating systems, programming languages, and database
access and communication protocols, with no dependence on proprietary
technology.



    EXTENSIVE INTEGRATION CAPABILITIES.  Our solution goes beyond application
programming interfaces, or APIs, to facilitate communications between a
business' computing systems with pre-built modules for Web-enabling today's
dominant business applications, such as those from SAP and PeopleSoft. Our
solution also includes tools that allow programmers to rapidly build new
integration modules for other applications, and generally enable complex
information answers to be generated from any data source within the enterprise,
no matter how remote or proprietary. These capabilities allow businesses to
marry existing systems to new information delivery platforms, thereby preserving
legacy investments.



    COMPREHENSIVE MANAGEMENT.  Our solution provides the necessary means to
monitor, administer and report on a business' entire Web infrastructure. These
advanced features provide the means to perform administrative and management
tasks easily and quickly, allow for real time reconfiguration of the information
infrastructure, assure minimum and/or differentiated levels of service, and
integrate with leading systems management utilities such as those from Computer
Associates, IBM Tivoli, BMC and Hewlett-Packard. Our solution automatically
generates alarms, alerts and reports, which allows for optimal performance of,
and powerful insight into, a business' Web infrastructure.


OUR GROWTH STRATEGY


    Our goal is to maintain and extend our position as a leading provider of Web
application server technology, enterprise application integration and Internet
commerce solutions. Our key growth strategies are to:



    MAINTAIN AND EXTEND TECHNOLOGICAL LEADERSHIP.  We believe that our
technology, solution and features represent a significant competitive advantage
and provide customer benefits that are not available from other solutions.
Highly advanced technological elements incorporated in our solutions
collectively contribute to the speed, scalability, reliability, manageability,
flexibility and extensibility of our product set. For more information on these
technological elements, see "--Technology." We believe that our consistent
record of technological industry firsts, as demonstrated recently by the release
of our Bluestone XML-Server, will continue into the future.



    EXPAND PRODUCT OFFERINGS.  We intend to continue to develop new products and
enhancements to existing products to fuel continued growth. Recently, we
introduced our XML suite of products, which expands the markets and applications
for our technology, with a focus on Internet commerce and inter-enterprise
information exchange. Upcoming enhancements to the Sapphire/Web suite consist of


                                       33
<PAGE>

enhanced Internet commerce services including the ability to provide
differentiated service levels based on user profiles, improved content and
presentation management capabilities, and significantly increased bandwidth,
transaction processing and security. Additional upcoming enhancements will
include improved high-end management features like reporting and control
systems, new business application capabilities and increased ease of use. We
expect to continue to make considerable investments in product development to
maintain this pace of innovation.



    CONTINUE TO FOCUS ON ENTERPRISE-SCALE SOLUTIONS.  An April 5, 1999 article
in PCWEEK ONLINE reported on an independent evaluation of our Web application
server framework against two competitive products. The evaluation employed a
simulated E-commerce site developed by Doculabs, an independent information
advisory company. In this evaluation, our solution posted throughput and
response time results that were 50% higher than our nearest competitor. In
addition, our solution was the only product able to meet the fault-tolerance
requirements of mission-critical and E-commerce applications. At the December
1998 Emerging Technology Conference sponsored by Giga Information Group, we
performed a live demonstration based on a PCWEEK Labs-designed benchmark and
successfully processed a variety of complex transactions at a rate of over 100
million interactions per day. Consequently, we believe that we are uniquely
positioned as a performance leader in our industry and will benefit as an
increasing number of large mission-critical systems move to the Web and as
Internet commerce grows.



    INCREASE MARKETING AND DIRECT SALES EFFORTS.  We intend to leverage our
previous customer successes by devoting significant marketing and direct sales
resources to specific industry verticals, including telecommunications,
insurance, brokerage, pharmaceuticals and E-commerce. We intend to increase the
number of field sales offices and field sales representatives over the next 12
months. Our direct sales organization is organized around named accounts,
geographic regions and, increasingly, industry verticals. As of June 30, 1999,
we had 52 employees in sales and marketing, 18 of which were quota-carrying
field sales representatives.


    FURTHER DEVELOP INDIRECT CHANNELS, PARTNERS AND ALLIANCES.  Our sales
efforts are leveraged by indirect channels and partners, and we intend to
continue to foster these relationships to fuel additional growth. These
channels, partners and alliances significantly extend our market reach and
overall opportunity set, and include the following:

    - independent software vendors, including Hewlett-Packard, Sanchez Computer
      Associates and Platinum technology;

    - systems integrators, including American Management Systems, Grant
      Thornton, KPMG, PricewaterhouseCoopers and approximately 65 others; and

    - value added distributors (VADs) and value added resellers (VARs),
      including Intraware and Merisel.

SERVICES AND SUPPORT

    We offer short-term mentoring, consulting and customer training services
through our Advanced Technology Group. We use our Advanced Technology Group
resources to assist our partners and clients in the early implementation
efforts, which tend to be less than one month in duration, and rely on our
systems integration partners to deliver longer-term professional integration
services. This strategy allows us to offer a higher degree of pre- and
post-sales support to our prospects, partners and licensees in support of
furthering the sales of our software products.

                                       35

    We have a Customer Support Group that provides ongoing maintenance and
support to customers through maintenance contracts. We furnish support through
the telephone and e-mail, as well as through a portion of our Web site called
Explore Web, which provides users with access to a comprehensive knowledge base
of the Sapphire/Web and XML suite solutions.


    We offer extensive training and certification for Sapphire/Web products as
well as course training in related topics, such as JAVA, XML and the Web in
general. Additionally, we also offer formal instruction through interactive
distance learning, which furnishes instruction through an innovative mix of
video, computer-based training and e-mail. We provide ongoing technical support
on a contractual basis to our licensees with annual maintenance agreements.


SALES AND MARKETING


    As of June 30, 1999, our sales and marketing organization consisted of 52
individuals, all of whom were based in North America. We had 18 field sales
representatives and 11 inside sales representatives, all of whom carry quotas.


    The sales force is comprised of three primary organizations: Named Accounts,
Direct Sales and Indirect Sales. We have diversified our sales activities to
support a target distribution of 70% indirect and 30% direct.


    We have sales offices in Sacramento, Los Angeles, Atlanta, Dallas, Chicago,
Boulder, San Francisco, Toronto and Mount Laurel, New Jersey. Sales outside
North America are generated by third party resellers in London, Seoul and
Sydney. We expect to open regional sales support offices in Europe and Asia
Pacific within the next twelve months.


    We support our sales efforts through corporate and field marketing
initiatives in North America. Our marketing organization focuses on creating
market awareness, generating leads, promoting our technology leadership and
educating independent research analysts. These efforts include public relations,
advertising, trade shows, alliance programs, seminars, direct mail,
telemarketing and marketing collateral that includes a Web site, brochures,
white papers and demonstrations.

STRATEGIC ALLIANCES

    We are building and maintaining significant working relationships with
complementary vendors that we believe will contribute to our ongoing success.
These relationships fall into four categories: strategic technology alliances,
independent software vendors, systems integrators and value added distributors
and resellers. Within our strategic technology alliances, we engage in
collaborative technology exchanges with BEA Systems, Computer Associates,
Informix, IBM, Level III Communications/PKS SI, Microsoft, Netscape,
OpenConnect, Oracle, Platinum technology, Sanchez Computer Associates and Sun
Microsystems, among others.

    We have relationships with independent software vendors, including
Hewlett-Packard, Platinum technology, OpenConnect, Sanchez Computer Associates
and Foundation Technologies. These partners deliver their application software
products with some element of our technology embedded therein. We maintain a
close working relationship with these partners and will continue to develop
relationships of this nature.

    We also maintain relationships with third party systems integrators who
deliver services to our end-user clients. These companies have been recruited to
deliver long term project support and are required to maintain a level of
proficiency in our products. These relationships include American Management
Systems, KPMG, Grant Thornton, PricewaterhouseCoopers and Level III
Communications/PKS SI.

                                       36
<PAGE>
    We have entered into formal two-tier distribution agreements with Intraware
and Merisel to deliver our suite of software products. These agreements provide
Intraware and Merisel with the right to distribute our products in North
America.

    We are a member in good standing of the Enterprise JAVA Bean Council, the
World Wide Web Consortium (W3C), the Object Management Group (OMG) and the
Enterprise Integration Council.

CUSTOMERS


    From 1996 through 1998, we licensed copies of our Sapphire/Web software to
more than 500 customers. Most of these customers began using our Sapphire/Web
products to Web-enable separate departmental systems and many of them are now
expanding their usage of Sapphire/Web to a company-wide basis. Accordingly, we
have observed a recent shift by our customers from creating Web applications to
creating enterprise applications that are Web-enabled.


    Our solutions are applicable to a wide variety of industries and are used by
many of the world's leading businesses. For example, Sapphire/Web users include:

    - three of the top five FORTUNE 500 companies in the electronics industry;

    - five of the top ten FORTUNE 500 companies in the computer equipment
      industry;

    - four of the top five FORTUNE 500 companies in the aerospace industry;

    - seven out of the top ten FORTUNE 500 companies in the telecommunications
      industry;

    - three of the top four FORTUNE 500 companies in the entertainment industry;
      and

    - five of the top ten FORTUNE 500 companies in the pharmaceuticals industry.


    Our customers include ARI, AT&T, Deutsche Bank, Dreyfus Corporation, Eli
Lilly, Hewlett-Packard, Houghton Mifflin Company, Just For Feet, MCI WorldCom,
OpenConnect and Reliance National. Each of these customers accounted for at
least $100,000 in revenue.



    Examples of successful Sapphire/Web implementations with representative
customers of ours include the following:


    - We helped ARI, a large international leasing company, establish its first
      Web application in 1998. That application enabled ARI's customers to
      inquire directly into ARI's leasing system to manage delivery and
      maintenance information for ARI's fleet.

    - Reliance National, a major insurance company, has been using Sapphire/Web
      software since 1997. Reliance National began with small departmental
      solutions. In 1998, Reliance National expanded its usage to include a
      system that decentralized its operations by communicating its risk
      management system to all of its associated brokers, thereby significantly
      expanding the speed in which the broker can prepare premium quotes and the
      manner in which Reliance National serves its customers.

    - AT&T and MCI WorldCom have each chosen our products to be used in customer
      loyalty and retention programs. These companies have engaged in projects
      to Web-enable their billing and reporting systems, thereby allowing their
      customers to review and approve bills through their Web site.


    - Several major publishers have used our products to further their Internet
      commerce initiatives. For example, Time, Inc. has utilized the
      Sapphire/Web solution to Web-enable the acquisition of pictures from its
      large database so that its customers can search for and purchase the
      images from its Web site. In another example, Houghton Mifflin Company, a
      text book publisher, has


                                       37
<PAGE>
      utilized the Sapphire/Web solution to provide an index of products
      available on its Web site, thereby considerably enhancing its customer
      service capabilities.

    - Several independent software vendors have entered into licensing
      arrangements with us in which our Sapphire/Web software becomes a core
      component for the next generation of their respective software products.
      For example, Platinum technology uses Sapphire/Web software as its next
      generation technology to move beyond the Web extension of legacy
      applications. In another example, Sanchez Computer Associates, a banking
      software provider, uses the Sapphire/ Web software as a foundation for its
      voice response and ATM systems. Additionally, Hewlett-Packard, a workflow
      and process management software vendor, uses Sapphire/Web software as its
      application integration engine, thereby giving it access to back-end
      legacy applications.

COMPETITION

    The market for our products is intensely competitive, highly fragmented and
characterized by rapid technological change and new product introductions.
Recently, several of our competitors have been acquired by large software
companies. Our competitors consist of a number of private and public companies
including, among others:

    - BEA Systems, which acquired WebLogic;

    - IBM;

    - Microsoft;

    - Oracle; and

    - Sun Microsystems, which acquired NetDynamics and the rights to Netscape's
      Application Server.

    In addition, we face competition from in-house software developers. Many of
our competitors have longer operating histories, significantly greater
financial, technical, marketing and other resources, greater name recognition, a
broader product range and a larger base of installed customers than us.

    We expect to face increased competition in the future from our current
competitors. In addition, new competitors, or alliances among existing and
future competitors, may emerge and rapidly gain significant market share. We may
also face increased competition in the future from existing large business
application and Internet software vendors that may broaden their product
offerings to include Web application server software. To the extent these
vendors are able to offer systems that are functionally comparable or superior
to our products, their significant installed customer bases, ability to offer a
broad solution and ability to price their products as incremental add-ons to
existing systems could provide them with a significant competitive advantage
over us.

TECHNOLOGY


    Our technology is based upon two concepts:



    - binding front-end objects to back-end objects which connects sources of
      data to users of data; and



    - protecting users from changes in technology.



    Specific technology features of the Bluestone solution include:



    100% PURE JAVA APPLICATION SERVER.  The JAVA platform offers enormous
benefits to us and our customers. Our products run on any platform where JAVA is
available and has been verified on operating systems such as Windows95,
Windows98, WindowsNT, Linux, all UNIX platforms including Sun, IBM and HP, as
well as the operating systems for IBM's mainframes and AS400 computers. JAVA


                                       38
<PAGE>

has also brought large productivity gains to our development team by decreasing
development time, eliminating porting costs and speeding time to market.



    LOAD BALANCING.  This is the fundamental technology that provides the high
performance and scalability for large applications and contributes to the fault
tolerant, or continuous operation, of the applications. A Load Balance Broker
runs in any number of Web servers in a Web server farm and manages the load
across any number of copies of Sapphire/UBS in that server farm. In addition,
the Load Balance Broker can be deployed as a portable mini-application, such as
a JAVA Bean or an Enterprise JAVA Bean, to allow utilization of the application
server from non-Web based applications. The Load Balance Broker has a unique
competitive advantage with a zero-feedback loop, a sophisticated technique to
direct work to non-busy resources that provides maximum speed and no practical
limits in terms of numbers of Load Balance Brokers and Web application servers
deployed.



    PERSISTENT STATE SERVER.  The persistent state server is also a key
component of fault tolerance. State servers are where "shopping cart"
information is held on Internet commerce sites while a user is shopping. It is
important that even if one of the application servers fails, the state
information is still available. A recent PCWEEK test substantiated
Sapphire/Web's significant lead in this high performance implementation of fault
tolerance.



    FAULT TOLERANT DESIGN.  Sapphire/Web has been designed to provide fault
tolerance, or nonstop operation, in a Web environment. There are two key pieces
to this technology. First, in the event of an application server failure, the
Load Balance Broker will redirect any requests from Web browsers to other
application servers. Second, the Persistent State Server will make a user's
state information continuously available, even if the application servers fail.



    LIVE OBJECT CACHE.  The Live Object Cache provides very high performance for
Internet commerce applications. The Live Object Cache holds data and programs
within the memory of the application server, reducing the time required for
accessing frequently used data. It is also contributes to fault tolerance by
working in conjunction with the persistent state server.



    CONTENT GENERATION OBJECTS.  Sapphire/Web has a powerful template processing
facility to generate Web pages dynamically. Content Generation Objects are
reusable JAVA classes, or computer programs, that can create content in a
consistent manner. This increases programmer productivity and provides Web
developers a simple mechanism to maintain a consistent look and feel to their
Web pages.



    SAPPHIRE/DEVELOPER DESIGN ENVIRONMENT.  This provides developers a highly
productive design environment for binding front-end objects to back-end objects.
Sapphire/Developer also maintains an open environment for integrating other
industry leading programming tools.



    BLUESTONE XML-SERVER COMMUNICATIONS SERVICES.  This program recognizes the
protocol of incoming communications and translates it to a request for service
to the XML-Server. XML documents can be passed to and from the XML server from
any combination of industry standard protocols. This separates the
communications from the processing of XML documents, so additional
communications services can be added without changing any code.


    BLUESTONE XML-SERVER DOCUMENT HANDLER SERVICES.  Bluestone's Document
Handlers are the JAVA programs that process XML documents. The Bluestone
XML-Server is unique in its ability to handle any XML document type via this
mechanism and its ability to dynamically load new document handler classes.

    BLUESTONE VISUAL-XML DESIGN ENVIRONMENT.  This open tool provides easy to
use creation of Bluestone XML-Server applications and creates XML documents in a
stand-alone mode. This tool is available on all platforms including Linux, UNIX
and Windows. We believe this tool expands the XML market to non-programmers.

                                       39
<PAGE>
    HOT VERSIONING AND HOT SWAPPING.  These new capabilities of Sapphire/Web
Release 6 are unique in providing companies the ability to run a full 24x7 Web
site. Hot Versioning allows Web applications to be upgraded between user clicks
with no session interruption. It includes testing in a production environment
and roll-forward and roll-back capabilities for versions of an application.
Sapphire/Web Release 6 also supports Hot Swapping so that applications can be
moved from server to server without interrupting service to the user.

    INTERNET QUALITY OF SERVICE.  This innovative capability provides for
differentiation of service based on each particular user. This allows for
priority customers to always get performance preference over other visitors to a
Web site.

PRODUCT DEVELOPMENT

    Historically, we have invested heavily in product development. Our future
success depends in large part on our ability to enhance existing products and
create new products that maintain and expand our technology lead. Accordingly,
we intend to continue to invest heavily in product development.


    As of June 30, 1999, we had 31 people in the product development group,
which includes a core group of senior developers and product development
leaders, junior developers, quality assurance and documentation personnel. Our
development team is located at our headquarters in Mount Laurel, New Jersey.
Almost all of our software is being developed in JAVA, thereby improving
productivity and reducing porting and testing costs.


    In an attempt to move our products at Internet-speed, we employ a small-team
approach with an interactive design/development/testing methodology that has
evolved over the past five years. To date, our product development group has
benefitted from a very low turnover rate.


    We are currently developing new releases to our Sapphire/Web and XML product
families. We anticipate that these new releases will bring even stronger
Internet commerce, high-end management, and ease of use capabilities, together
with integrated Internet commerce solutions for SAP and PeopleSoft in joint
development with our systems integration partners. We expect these new releases
to continue to position our products as the most "feature-rich" in the market.


EMPLOYEES


    As of June 30, 1999, we had 152 employees, of which 52 were employed in
sales and marketing, 38 were employed in services, 31 were employed in product
development and 31 were employed in general and administrative positions. None
of our employees are represented by unions. We believe that our relations with
our employees are good.


PROPERTIES

    Our principal executive and administrative offices are located in
approximately 41,000 square feet of office space in Mount Laurel, New Jersey. We
also maintain sales offices in Sacramento, Los Angeles, Atlanta, Dallas,
Chicago, Boulder, San Francisco, Toronto and Mount Laurel, New Jersey. Annual
lease payments on the Mount Laurel facility are approximately $480,000. This
lease expires in November 2003. We do not own any real property.

LEGAL PROCEEDINGS

    We are from time to time a party to litigation arising in the ordinary
course of our business. We are not currently a party to any material litigation.

    AGGREGATED OPTION EXERCISES IN LAST FISCAL YEAR AND FISCAL YEAR-END OPTION
     VALUES


    The following table presents information with respect to stock options owned
by the named executive officers at December 31, 1998 and with respect to stock
options exercised by the named executive officers during the fiscal year ended
December 31, 1998.


    There was no public trading market for the common stock as of December 31,
1998. Accordingly, the values of unexercised options set forth below have been
calculated on the basis of the assumed initial public offering price of $12.00
per share, less the applicable exercise price per share, multiplied by the
number of shares underlying these options.

EMPLOYMENT AGREEMENTS


    We entered into an employment agreement with Mel Baiada in April 1997 which
was modified in January 1999 and which expired without being renewed on June 30,
1999. Under this agreement, in 1998 we paid Mr. Baiada a salary of $158,654 and
a $22,215 bonus. This agreement imposes a one year period after termination in
which Mr. Baiada may not compete against us. This agreement also provides that
Mr. Baiada will retain a position on the board of directors until the later of:



    - the date his ownership interest in our outstanding common stock, assuming
      conversion of all outstanding convertible securities, drops below 10%; and



    - June 30, 2000.



    For the twelve months commencing on July 1, 1999, Mr. Baiada will receive
$150,000 plus customary benefits as severance under his agreement. As of June
30, 1999, we recorded $154,200 in general and administrative expense associated
with this severance agreement. On July 1, 1999, Mr. Baiada's shares of common
stock deemed to be contingent under his stock repurchase agreement dated April
18, 1997 became vested. For more information about Mr. Baiada's stock repurchase
agreement see "Certain Transactions--Stock Repurchase Agreement."



    We also entered into an employment agreement with Robert Bickel in April
1997 which may be terminated by us or Mr. Bickel at any time, with or without
cause. Under this agreement, in 1998 we paid Mr. Bickel a base salary of
$155,330 and a bonus of $19,554. Future increases to these amounts are at the
discretion of the board of directors. This employment agreement calls for the
payment of customary fringe benefits. Under this employment agreement, Mr.
Bickel has agreed not to compete against us for a period of one year after the
termination of his employment. In addition, as part of this employment
agreement, we granted to Mr. Bickel an option to purchase 93,750 shares of
common stock at an exercise price of $2.24 per share, the fair market value of
the common stock on the date of grant. The option vests in 16 equal installments
on a quarterly basis over a four-year period beginning as of the date of grant.


SEVERANCE AGREEMENTS

    Messrs. Kilroy, Bickel, Capobianco and Ballezzi are parties to separate
severance agreements with us which call for the following payments and benefits
to be received upon the termination of their employment other than for cause:


    - 12 months of salary and benefits plus an additional month of salary and
      benefits for each year of service;


    - accrued vacation;

    - 6 months of outplacement services up to $12,000; and

    - 50% vesting on all outstanding unvested options and the extension of the
      exercise period on all vested options to five years.


    Mr. Ballezzi's employment with us will terminate effective September 30,
1999. As of June 30, 1999, we recorded $208,700 in general and administrative
expense associated with his severance agreement.


EMPLOYEE CONFIDENTIALITY AGREEMENTS

    We enter into agreements with all of our employees containing provisions
regarding confidentiality and assignment of inventions.

EXECUTIVE BONUS POOL



    Our board of directors has established an executive bonus pool of 384,794
shares of common stock issuable to our chairman, executive and certain other
officers under our stock option plan. Grants of awards under the bonus pool are
contingent upon our meeting predetermined revenue and profit goals on a
quarterly and annual basis in 1999. Our chairman and officers will receive
grants of immediately vested options from the pool on a quarterly and annual
basis if we determine that we have met our profit and revenue goals.



    The following table sets forth the total amount of shares that each of our
chairman and executive officers may receive under the bonus pool:



<TABLE>

Mel Baiada.........................................................     39,063
</TABLE>



    We met our quarterly revenue and profit goals in each of our first two
quarters of 1999 and options covering 52,650 shares of common stock were granted
in May 1999 and options to purchase 60,259 shares will be granted in August
1999.


STOCK OPTION PLAN

    On July 1, 1998, the board of directors adopted the Amended and Restated
Bluestone Software, Inc. 1996 Incentive and Non-Qualified Stock Option Plan,
which replaced all of our previous plans. Our option plan is administered by our
board of directors or a committee of at least two persons appointed by the board
of directors. The option plan permits the payment of the exercise price to be in
the form of cash, check, cashless exercise and such other consideration and
method of payment as the administrator of the plan may, from time to time
determine. Optionees are required to execute a stock purchase and restriction
agreement at the time he or she exercises any options.


    As of June 30, 1999, a total of 2,946,578 shares of common stock were
authorized for issuance to directors, officers, employees and consultants
selected by the administrator of the option plan. Of these shares, 2,663,589
shares of common stock were issuable upon the exercise of stock options granted
under the option plan. The following table summarizes the option holdings of our
chairman and executive officers as of June 30, 1999:

</TABLE>



    Until the option plan terminates, any unpurchased shares of common stock
underlying all options that expire, are terminated or become unexercisable for
any reason, are returned to the option plan and become available for future
grants. The number of shares of common stock underlying an option, the total
number of shares of common stock authorized under the option plan but for which
no options have been granted, and the exercise price per share of the common
stock underlying all outstanding options are proportionately adjusted for any
increase or decrease in the number of outstanding shares


                                       48
<PAGE>
of common stock resulting from stock splits, reverse stock splits, stock
dividends, reclassifications and recapitalizations.


    The option plan provides for the grant of either incentive stock options
("ISOs") or non-qualified stock options ("NQSOs"), except that consultants of
Bluestone who are not also employees are not entitled to receive ISOs under the
option plan. Exercise prices for ISOs may not be less than the fair market value
per share of common stock on the date of grant, or 110% of the fair market value
in the case of ISOs granted to any person who owns our stock possessing 10% or
more of the total voting power of all of our capital stock. Exercise prices for
NQSOs may be less than the fair market value per share, but must be at least
$0.01 per share. Until there is an established market for the common stock, the
board of directors, at its discretion, determines the fair market value of a
share of common stock. Unless otherwise specified by the terms of an option
agreement, options granted under the option plan vest at a rate of 25% of the
shares underlying the option per year during the consecutive 4 year period
beginning on the date of grant and expire 10 years after the date of grant, or 5
years after the date of grant with respect to ISOs granted to any person who
owns our stock possessing 10% or more of the total voting power of all of our
capital stock. In July 1998, our board of directors authorized us to grant
options to employees with a vesting period that commences on the later of:



    - their date of hire; or



    - March 1, 1996 (the inception date of the option plan).



Generally, all employee stock option grants made after July 1998 contain this
modified vesting arrangement.



    The number of shares of common stock covered by ISOs granted to any optionee
is limited so that the total fair market value of stock, determined as of the
date of grant, with respect to which ISOs are exercisable for the first time by
such optionee in any calendar year does not exceed $100,000. Any options in
excess of such limits would be treated as NQSOs.



    In the event of a sale of Bluestone, as defined in the option plan, 50% of
all options that have not vested as of the date of the sale become immediately
vested and exercisable. All remaining options vest in accordance with the
vesting schedule set forth in the applicable option agreement. In the event of a
change in control of Bluestone, as defined in the option plan, the board of
directors has the right, in its sole discretion, to accelerate the vesting of
all options that have not vested as of the date of the change in control or
establish an earlier date for the expiration of the exercise of an option or
both. In addition, in the event of a change in control of Bluestone, the board
of directors may, in its sole discretion, subject to and conditioned upon a sale
of Bluestone, arrange for the successor entity to assume all of the rights and
obligations under the option plan. Alternatively, the board of directors may, in
its sole discretion, terminate the option plan and:



    - with respect to those options that are vested as of the date of the sale
      of Bluestone, pay an amount equal to the amount over which the fair market
      value of a share of common stock, exceeds the underlying exercise price
      for those options;



    - arrange for the exchange of all options for options to purchase common
      stock in the successor entity; or



    - distribute to each optionee other property in an amount equal to and in
      the same form as the optionee would have received from the successor
      entity if the optionee had owned the shares of common stock underlying
      options that were vested as of the date of the sale of Bluestone rather
      than the option at the time of the sale of Bluestone. In this instance,
      the fair market value will be determined as of the termination date of the
      option plan. The form of payment or distribution to the optionee is to be
      determined by the board of directors, in its sole discretion.

401(k) PLAN

    We maintain a 401(k) Plan/Profit Sharing Plan. Under our 401(k) plan, a
participant may contribute, subject to some limitations contained in the
Internal Revenue Code, up to 15% of his or her compensation to the 401(k) plan.
Employees who are at least 21 years old are eligible to participate after six
consecutive months of employment with Bluestone.

    We may make discretionary matching contributions into participants' accounts
of an annually determined percentage. This percentage is subject to a maximum of
6% of a participant's total eligible compensation. In addition, we may make
additional annual discretionary profit sharing contributions to participants'
accounts each year at the discretion of the board of the directors. Any profit
sharing allocations made are allocated in the ratio that a participant's total
eligible compensation bears to the total eligible compensation of all eligible
participants for the applicable 401(k) plan year. To be eligible for a
discretionary profit sharing contribution, a participant must be employed with
Bluestone on the last day of the applicable 401(k) plan year and must have
completed at least 500 hours of service for Bluestone during that year.

    The portion of a participant's account attributable to his or her own
contributions is 100% vested. The portion of the account attributable to our
contributions vests as to 20% of these contributions each year over 5 years
beginning after completion of 2 years of service with us and ending after 6
years of service with us. Distributions from the 401(k) plan may be made in the
form of installment distributions or lump-sum cash payments.

LIMITATION OF LIABILITY OF DIRECTORS AND INDEMNIFICATION OF DIRECTORS AND
  OFFICERS

    As permitted by the Delaware General Corporation Law, as amended, our
certificate of incorporation provides that our directors shall not be liable to
us or our stockholders for monetary damages for breach of fiduciary duty as
directors to the fullest extent permitted by the Delaware General Corporation
Law as it now exists or as it may be amended. The Delaware General Corporation
Law permits limitations of liability for a director's breach of fiduciary duty
other than liability:

    - for any breach of the director's duty of loyalty to us or our
      stockholders;

    - for acts or omissions not in good faith or which involve intentional
      misconduct or a knowing violation of law; or

    - for any transaction from which the director derived an improper personal
      benefit.

    In addition, our bylaws provide that we shall indemnify all of our
directors, officers, employees and agents for acts performed on our behalf.

                              CERTAIN TRANSACTIONS


SPIN-OFF OF CONSULTING BUSINESS



    In April 1997, we had two operating businesses, the software products
business and the professional consulting services business. At that time and
after our reincorporation from a New Jersey corporation into a Delaware
corporation, all of our issued and outstanding common stock was owned by Mel
Baiada. In order to enable investors to provide capital in connection with the
software products business, we separated the consulting business and the
products business by spinning off the consulting business to Mel Baiada.



    To accomplish the spin-off, we created BCI and entered into a contribution
and distribution agreement dated April 17, 1997 with BCI. Under the contribution
and distribution agreement, we contributed to BCI those assets and liabilities
that constituted the services business in exchange for all of the stock of BCI.
We then distributed all of the stock of BCI to Mel Baiada. At the time of the
distribution, both Bluestone and BCI were "S" corporations for federal income
tax purposes.



TRANSACTIONS IN CONNECTION WITH THE SPIN-OFF



    MARK BAIADA CONVERTIBLE SUBORDINATED NOTE



    To achieve an equal distribution of debt between us and BCI in connection
with the spin-off, we agreed to assume one-half of the $1.0 million principal
amount of a convertible note payable by Bluestone Consulting, the former New
Jersey corporation, to Mark Baiada, formerly a director of ours and the brother
of Mel Baiada. BCI assumed the liability for the other one-half of the note. At
the time we borrowed the $1.0 million, the proceeds were used for general
working capital purposes. We effected this assumption by issuing an amended and
restated convertible subordinated note dated April 17, 1997 to Mark Baiada in
the principal amount of $500,000. The note payable to Mark Baiada bears interest
at a rate of 10% per annum, compounded annually. We are required to make
interest payments in arrears on each anniversary date of this note until paid in
full. The principal amount of the note is payable in full on December 31, 2002.
We are permitted to prepay the note in whole or in part without penalty or
premium.



    The amount outstanding under the note is convertible into 218,750 shares of
our common stock at any time prior to the time it matures or the date paid in
full at a rate equal to $2.29 per share, subject to proportionate adjustment in
the event we pay out stock dividends in shares of common stock or subdivide or
combine our outstanding common stock.


    MEL BAIADA PROMISSORY NOTE AND PURCHASE OF SERIES A PREFERRED STOCK


    As part of the spin-off, Mel Baiada agreed to cancel a promissory note in
the principal amount of $403,066 originally issued by Bluestone Consulting, the
former New Jersey corporation, in exchange for (1) our issuance to him of a
promissory note in the principal amount of $250,000 and (2) BCI's issuance to
him of a promissory note in the principal amount of $107,495. The promissory
notes were allocated between BCI and us as part of the negotiated distribution
of net assets in the spin-off. Bluestone Consulting, the former New Jersey
corporation, used the $403,066 for general working capital purposes.
Concurrently with our issuance of the Series A preferred stock on April 18,
1997, Mel Baiada contributed our note payable to him to our capital in exchange
for 263,158 shares of Series A preferred stock.


    PROMISSORY NOTE TO BCI


    To achieve an equal distribution of debt between BCI and us as part of the
spin-off, we issued a subordinated promissory note dated April 17, 1997 to BCI
in the principal amount of $500,000 that bears interest at a rate of 10% per
annum. We are required to make interest payments in arrears on


                                       51
<PAGE>
each anniversary date of the note until paid in full. The principal amount of
the note is payable in full on December 31, 2005. We are permitted to prepay the
note in whole or in part without penalty or premium.


    SERVICE MARK LICENSE AGREEMENT



    As part of the spin-off, we entered into a service mark license agreement
dated April 17, 1997 with BCI. Under this license agreement, we granted BCI a
non-exclusive, perpetual, worldwide royalty-free license to use some of our
registered and unregistered trade marks in connection with any services
performed by BCI. We have the right to terminate the license agreement upon:



    - certain events of default by BCI; or



    - a change in control of BCI, subject to BCI's right to continue the license
      agreement for a period of not more than 1 year from the date of the change
      in control.



    ISSUANCE OF SERIES A PREFERRED STOCK AND STOCK REPURCHASE AGREEMENT



    On the day immediately after the date of the spin-off, and pursuant to a
stock purchase agreement dated April 18, 1997, we issued 5,526,316 shares of
Series A preferred stock for a total cash purchase price of $5.25 million or
$0.95 per share, including 263,158 shares of Series A preferred stock to Mel
Baiada and 5,263,158 shares of Series A preferred stock to the entities
affiliated with Patricof & Co. Ventures, Inc. and Fostin Capital Partners II,
L.P. Holders of Series A preferred stock are entitled to receive annual
dividends of $0.57 per share. Proceeds of the issuance of the Series A preferred
stock were used for general working capital purposes. Each share of our Series A
preferred stock was initially convertible into one share of our common stock,
subject to some anti-dilution protections. As a result of the stock split, each
share of our Series A preferred stock will convert into 0.3125 shares of our
common stock.



    We entered into a stock repurchase agreement dated April 18, 1997 with Mel
Baiada as an incentive for Mr. Baiada to remain with us and devote his full-time
and efforts to us. To this end, we also entered into an employment agreement
with Mr. Baiada which is more fully described in this prospectus under the
heading "Management--Employment Agreements." Under the repurchase agreement,
421,875 shares of the 2,812,500 shares of common stock then held by Mr. Baiada
were designated as "contingent shares" which were subject to repurchase at our
option if Mr. Baiada ceased to be employed by us at a purchase price equal to
the fair market value as determined by our board of directors. At the beginning
of each calendar quarter, beginning with the third calendar quarter of 1997 and
until the second calendar quarter of 2001, 26,367 of the contingent shares were
to be reclassified as "vested shares," reducing the total number of "contingent
shares" by 26,367 at the beginning of each calendar quarter. Because Mr.
Baiada's employment agreement was not renewed on July 1, 1999, all outstanding
contingent shares automatically became vested shares.



    TAX ALLOCATION AND INDEMNITY AGREEMENT



    As a result of the spin-off, we, BCI and Mel Baiada needed to decide how our
taxes, and the taxes of BCI would be determined for the year of the spin-off,
and how we would deal with any adjustment to taxes to us and Mel Baiada that
resulted after the spin-off because of a tax audit. These matters are addressed
in the tax allocation and indemnity agreement dated April 18, 1997. The
agreement provides that:



    - with respect to federal income taxes, we closed our books as of the day
      before the issuance of the preferred stock, so that the income and
      expenses earned in the year of the spin-off, before the issuance of the
      preferred stock, were not included in our corporate income tax return for
      the year of the spin-off. They were included in our final federal income
      tax return for the period


                                       52
<PAGE>

      that we had elected to be an S corporation for federal income tax
      purposes, and flowed through to the tax return of Mel Baiada;



    - with respect to state income taxes and taxes that were not imposed on
      income, such as property taxes, we allocated them between us and BCI based
      on the reasonable determination of the boards of directors BCI and us;



    - if we undergo a tax audit that results in us increasing our tax liability
      for the period after the spin-off, Mr. Baiada will reimburse us for the
      additional tax cost, if there is a corresponding reduction in income in an
      open tax return in a year when we were an S corporation, and he realizes a
      tax benefit because of the decrease in income in the S corporation year;



    - if we undergo a tax audit that results in an increase in our income while
      we were an S corporation, and also results in a decrease in our income for
      a period after the spin-off, we will reimburse Mr. Baiada any additional
      tax cost he incurs because of the increase in the income in the S
      corporation return; and



    - if our election to be treated as an S corporation is deemed invalid or
      terminated for a reason other than the issuance of the preferred stock,
      Mr. Baiada will reimburse us for any tax costs that we incur, to the
      extent he receives a tax benefit from the change in our status, and if Mr.
      Baiada has additional tax liability imposed on him because of the
      termination, we will indemnify him for the costs.



    There have been no claims made under the agreement, by either party, for
reimbursement.



    RESELLER AGREEMENT WITH BCI



    We are a party to a reseller agreement with BCI, dated January 1, 1998.
Under the reseller agreement, BCI is a non-exclusive reseller of our products in
the United States and Canada. BCI may purchase products from us at our then
current list prices less our standard quantity discounts. The material terms and
conditions contained in the reseller agreement are similar to those contained in
our standard reseller agreement.


    SUBLEASE AGREEMENT WITH BCI


    As part of the spin-off, we entered into a sublease agreement with BCI,
effective as of April 30, 1997. BCI subleases approximately 7,780 square feet of
our Mount Laurel facility. BCI pays us an annual base rent of $94,000, which is
paid in equal monthly installments in advance on the first day of every calendar
month during the term of the BCI sublease. The rental charges to BCI were
determined on a pro-rata square footage basis at the same rate and under the
same terms that we have with our landlord. BCI also pays us 19% of all taxes,
common area costs, utility costs and other services paid for by us under our
lease. The BCI sublease expires when our lease expires or is terminated for any
reason, including our default under our lease.


SALE OF MEL BAIADA SERIES A PREFERRED STOCK


    On April 22, 1998, Mel Baiada sold all 263,158 of his shares of Series A
preferred stock to certain of the then existing holders of Series A preferred
stock for a total purchase of $341,053 or $1.296 per share.


ISSUANCE OF SERIES B PREFERRED STOCK


    Pursuant to a stock purchase agreement dated April 22, 1998, we issued
8,782,695 shares of Series B preferred stock for a total purchase price of $11.4
million or $1.296 per share, including 3,858,025 shares of Series B preferred
stock to General Electric Capital Corporation and 4,924,670


                                       53
<PAGE>

shares of Series B preferred stock to the entities affiliated with Patricof &
Co. Ventures, Inc. and Fostin Capital Partners II, L.P. Holders of Series B
preferred stock are entitled to annual dividends of $0.078 per share. The
proceeds of the issuance of the Series B preferred stock were used for general
working capital purposes. Each share of our Series B preferred stock was
initially convertible into one share of our common stock. Under the terms of our
Series B issuance, the conversion ratio changed as of December 31, 1998 so that
each share of our Series B preferred stock became convertible into 2.09 shares
of our common stock. As a result of the stock split, each share of our Series B
preferred stock will convert into 0.6541 shares of our common stock.


BRIDGE FINANCING


    On January 21, 1999, we entered into the Note and Warrant Purchase Agreement
with substantially all of the holders of the Series B preferred stock. Under the
Note and Warrant Purchase Agreement, the Series B preferred stockholders agreed
to provide subordinated secured debt financing of up to $5.0 million for general
working capital purposes. To the extent this financing was utilized, we would
have been obligated to issue 10% convertible subordinated secured notes and
warrants to purchase up to 504,032 shares of common stock at an exercise price
equal to $1.98 per share to the Series B preferred stockholders. We were
permitted to draw on the Committed Principal Amount at any time until May 30,
1999.



    As of May 25, 1999, we had drawn down approximately $1.35 million of the
$5.0 million available to fulfill general working capital needs and issued
137,609 warrants to the Series B preferred stockholders. This outstanding $1.35
million debt was converted into Series C preferred stock as part of our issuance
of 9,191,176 shares of Series C preferred stock at $2.72 per share on May 25,
1999.



    The issuance of the warrants to the Series B preferred stockholders
triggered anti-dilution protection afforded to Silicon Valley Bank pursuant to
an antidilution agreement between us and Silicon Valley Bank dated November 24,
1997, whereby the number of shares of common stock underlying a warrant issued
to Silicon Valley Bank were readjusted from 8,224 to 9,766 shares of our common
stock and the exercise price under the Silicon Valley Bank warrant was
readjusted from $3.04 to $2.56 per share.


ISSUANCE OF SERIES C PREFERRED STOCK


    Pursuant to a stock purchase agreement dated May 25, 1999, we issued
9,191,176 shares of Series C preferred stock for a total purchase price of $25.0
million or $2.72 per share, including 676,524 shares of Series C preferred stock
to General Electric Capital Corporation and 1,161,709 shares of Series C
preferred stock to the entities affiliated with Patricof & Co. Ventures, Inc.
and Fostin Capital Partners II, L.P. Holders of Series C preferred Stock are
entitled to annual dividends of $0.1632 per share. The proceeds of the issuance
of the Series C preferred stock were used for general working capital purposes.
Each share of our Series C preferred stock was initially convertible into one
share of our common stock. As a result of the stock split, each share of our
Series C preferred stock will convert into 0.3125 shares of our common stock.


REGISTRATION RIGHTS


    Under the second restated investors' rights agreement dated May 25, 1999 by
and among us and our preferred stockholders, the holders of preferred stock are
entitled to certain rights with respect to the registration under the Securities
Act for resale to the public of our common stock issuable upon the conversion of
preferred stock. The second restated investors' rights agreement permits the
preferred stockholders to twice require us, whether or not we propose to
register our common stock for sale, to register all or part of those preferred
stockholders' common stock, issued upon conversion of the preferred stock, so
long as the securities that would be covered by the registration statement


                                       54
<PAGE>
have an aggregate gross offering price of at least $20.0 million. If any
registration involves an underwritten offering, preferred stockholders that wish
to participate in that offering must enter into customary agreements with us and
the underwriter. The underwritten offering will be subject to certain
limitations and restrictions that may be imposed by the underwriters thereof,
including, the right of the underwriters to exclude a portion of the securities
owned by the preferred stockholders from the offering.


    The second restated investors' rights agreement also provides demand
registration rights to the preferred stockholders requiring us to register all
or part of the registrable securities on Form S-3, provided, that, among other
things:



    - Form S-3 is available to us and the preferred stockholders for this
      offering;



    - the offering price of the securities to be registered by the preferred
      stockholders, together with securities held by other persons entitled to
      participate in the registration, is at least $1.0 million in the
      aggregate, net of any underwriters' discounts or commissions; and



    - the board of directors determines that the registration would not be
      seriously detrimental to us and our stockholders at that time. In this
      event, the registration of these securities may be delayed for up to 60
      days.



    Under the second restated investors' rights agreement, the preferred
stockholders have the right, subject to several exceptions, to have their
registrable securities included in any registration statement filed by us. Each
preferred stockholder that wishes to participate in the offering must enter into
a customary agreement with us and the underwriter, which may limit in whole or
in part the inclusion of that preferred stockholder's registrable securities in
the registration statement, as determined by the underwriters in their sole
discretion.



    We are required to pay all expenses relating to any of these registrations
other than underwriting discounts and commissions relating to shares sold by the
preferred stockholders. The registration rights provided in the second restated
investors' rights agreement extend for a period of five years following this
offering.


FILIPOWSKI CONSULTING AGREEMENT


    We entered into a consulting agreement with Andrew Filipowski in May 1999
under which Mr. Filipowski will provide strategic and general business
consulting services to us from that date until May 2001. In consideration of
these consulting services, we granted to Mr. Filipowski a fully vested option to
purchase 21,875 shares of our common stock at an exercise price of $4.13 per
share. We recorded general and administrative expenses of $165,784 in the three
months ended June 30, 1999 in connection with this option.


FUTURE AFFILIATE TRANSACTIONS


    We believe that all of the transactions described above were made on terms
no less favorable to us than would have been obtained from unaffiliated third
parties. All future transactions, including loans, between us and our officers,
directors, principal stockholders and their affiliates, will be approved by a
majority of the board of directors, including a majority of the independent and
disinterested outside directors on the board of directors, and will be on terms
no less favorable to us than could be obtained from unaffiliated third parties.

<PAGE>
                       PRINCIPAL AND SELLING STOCKHOLDERS


    The following table sets forth certain information as of July 31, 1999
regarding the beneficial ownership of our common stock by: (1) each person,
entity or group known by us to own beneficially more than 5% of our outstanding
common stock; (2) each director; (3) each of the named executive officers; and
(4) all directors and executive officers as a group. The ownership amounts are
calculated as if the outstanding preferred stock and accrued dividends on
preferred stock were fully converted into common stock as of June 30, 1999.
Unless otherwise indicated, the address of each person identified is c/o
Bluestone Software, Inc., 1000 Briggs Road, Mount Laurel, New Jersey 08054.



    The percentages shown are based on 13,302,473 shares of common stock
outstanding prior to the offering and 17,302,473 shares of common stock
outstanding after the offering. Pursuant to Rule 13d-3 under the Exchange Act,
shares of common stock which a person has the right to acquire pursuant to the
exercise of stock options and warrants held by that holder that are exercisable
within 60 days are deemed outstanding for the purpose of computing the
percentage ownership of that person, but are not deemed outstanding for
computing the percentage ownership of any other person.

                           DESCRIPTION OF SECURITIES


    Our authorized capital stock as of June 30, 1999 consisted of 53,800,000
shares of common stock, par value $0.001 per share, and 23,500,187 shares of
preferred stock, par value $0.001 per share, of which 5,526,316 shares were
designated as "Series A preferred stock," 8,782,695 shares were designated as
"Series B preferred stock," and 9,191,176 shares were designated as "Series C
preferred stock." Immediately prior to the closing of this offering, we will
authorize additional shares of common and preferred stock and all of the
outstanding preferred stock will automatically convert to common stock.


    The following is a summary of certain provisions of our common stock, our
preferred stock and our third amended and restated certificate of incorporation.

COMMON STOCK


    As of June 30, 1999, there were 2,819,955 shares of common stock held of
record by 11 stockholders. Holders of common stock, together with the holders of
the preferred stock, who are entitled to vote on an "as converted" basis as
described below, are entitled to one vote for each share held on all matters
submitted to a vote of stockholders and do not have cumulative voting rights.
Subject to the applicable provisions of the Delaware General Corporation Law,
stockholders holding a majority of the issued and outstanding shares entitled to
vote constitute a quorum for the purposes of convening a stockholders' meeting.
Accordingly, a majority of a quorum may elect directors standing for election,
subject to the director election rights of the stockholders described below.
Holders of common stock are entitled to receive ratably any dividends as may be
declared on the common stock by the board of directors. Upon liquidation,
dissolution or winding up of Bluestone, holders of common stock are entitled to
receive ratably the net assets of Bluestone available for distribution after the
payment of all debts and other liabilities subject to the prior and superior
liquidation preference rights of holders of preferred stock, if any are
outstanding. Holders of common stock have no preemptive or subscription rights
with respect to other issuances of securities. Our common stock has no
conversion rights and is not redeemable.


PREFERRED STOCK

    All of our presently authorized preferred stock is outstanding. Immediately
prior to this offering's closing, all outstanding preferred stock will
automatically convert into common stock as follows:


    - Series A: one share of Series A preferred stock for 0.3125 shares of
      common stock;



    - Series B: one share of Series B preferred stock for 0.6541 shares of
      common stock; and



    - Series C: one share of Series C preferred stock for 0.3125 shares of
      common stock.


    Holders of our outstanding preferred stock are entitled to receive annual
dividends as follows:


    - Series A: $0.057 per share;



    - Series B: $0.078 per share; and



    - Series C: $0.1632 per share.



    The Series A preferred stock dividends have accrued since April 17, 1997,
the Series B preferred stock dividends have accrued since April 22, 1998 and the
Series C preferred stock dividends have accrued since May 25, 1999. Aggregate
accrued dividends on the preferred stock as of June 30, 1999 amounted to
approximately $1.7 million.


    We are required to pay any federal or state income taxes to which the
holders of preferred stock may be subject with respect to the accrued and unpaid
cash dividends, whether or not earned or declared. Accumulated but unpaid
dividends will be reduced by these tax payments. Upon the

                                       59
<PAGE>
conversion of our preferred stock into common stock, we are required to pay to
the holders of the preferred stock being converted all accumulated and unpaid
cash dividends, whether or not declared, with respect to the preferred stock.
However, if requested by any holder of the shares of preferred stock being
converted and approved by the holders of a majority of the then outstanding
shares of common stock, the holder may exchange all or any portion of the
accumulated and unpaid cash dividends into shares of common stock at the then
fair market value of the common stock.

ANTI-TAKEOVER EFFECTS OF BLUESTONE'S CERTIFICATE OF INCORPORATION AND BYLAWS AND
PROVISIONS OF DELAWARE LAW

    Following the closing of this offering, our certificate of incorporation and
bylaws and provisions of Delaware corporate law may hinder or delay a third
party's attempt to acquire us. They may also make it difficult for the
stockholders to remove incumbent management.

    CLASSIFIED BOARD OF DIRECTORS; VACANCIES.  Following the closing of this
offering, the certificate of incorporation will divide the board of directors
into three classes. The directors' terms will be staggered by class. Our
classified board of directors is intended to provide continuity and stability in
board membership and policies. However, the classified board of directors makes
it more difficult for stockholders to change the board composition quickly. In
addition, a majority of the directors then in office can increase the size of
the board of directors and fill board of directors vacancies and newly created
directorships resulting from any increase in the size of the board of directors.
This is true even if those directors do not constitute a quorum or if only one
director is left in office. These provisions could prevent stockholders,
including parties who want to take over or acquire us, from removing incumbent
directors without cause and filling the resulting vacancies with their own
nominees.

    ADVANCE NOTICE PROVISIONS FOR STOCKHOLDER PROPOSALS AND STOCKHOLDER
NOMINATIONS OF DIRECTORS. The bylaws will establish an advance notice procedure
regarding nominations of directors by stockholders and other stockholder
proposals. The advance notice procedure will not apply to nominations of
directors by the board of directors. For matters a stockholder wishes to bring
before an annual meeting of stockholders, the stockholder must deliver to us a
notice not less than 90 days nor more than 120 days before the first anniversary
of the preceding year's annual meeting of nominations and other business to be
brought before our annual meeting. The stockholder must put information in the
notice regarding:

    - the stockholder and its holdings;

    - the background of any nominee for director;

    - the written consent to being named as a nominee and to serving as a
      director if elected;

    - any business desired to be brought before the meeting;

    - the reasons for conducting the business at the meeting; and

    - any material interest of the stockholder in the business proposed.

    At a special meeting of stockholders called to elect directors, stockholders
can make a nomination only if they deliver to us a notice that complies with the
above requirements no later than the tenth day following the day on which public
announcement of the special meeting is made. The bylaws could preclude a
nomination for the election of directors or the conduct of certain business at a
particular meeting if the proper procedures are not followed. This may
discourage or deter a third party from conducting a solicitation of proxies to
elect its own slate of directors or otherwise attempting to obtain control of
us.

    SPECIAL STOCKHOLDERS' MEETINGS.  Our certificate of incorporation and bylaws
will permit special meetings of the stockholders to be called only by the board
of directors, the chief executive officer or

                                       60
<PAGE>
the president or holders of at least 75% of our securities that are outstanding
and entitled to vote in an election of directors.

    AUTHORIZED BUT UNISSUED SHARES.  We will be able to issue shares of common
stock without stockholder approval, up to the number of shares authorized for
issuance in its certificate of incorporation, except as limited by Nasdaq rules.
We could use these additional shares for a variety of corporate purposes. These
purposes include future public offerings to raise additional capital, corporate
acquisitions and employee benefit plans. Our ability to issue these additional
shares could make it more difficult or discourage an attempt to obtain control
of us by means of a proxy contest, tender offer, merger or otherwise.

    SECTION 203 OF DELAWARE LAW.  After this offering is completed, Section 203
of the Delaware General Corporation Law will apply to us. This section will
prohibit us from engaging in a "business combination" with an "interested
stockholder." This restriction will apply for three years after the date of the
transaction in which the person became an interested stockholder, unless the
business combination is approved in a prescribed manner. A "business
combination" includes (1) mergers, (2) asset sales and (3) other transactions
resulting in a financial benefit to an interested stockholder. Generally, an
"interested stockholder" is a person who, together with affiliates and
associates, owns, or within three years did own, 15% or more of our voting
stock. Section 203 could delay, defer or prevent a change in control of us. It
might also reduce the price that investors might be willing to pay in the future
for shares of common stock.

TRANSFER AGENT AND REGISTRAR


    The transfer agent and registrar for the common stock is StockTrans, Inc.


LISTING

    We have applied for listing our common stock on the Nasdaq National Market
under the trading symbol "BLSW."

                        SHARES ELIGIBLE FOR FUTURE SALE


    Prior to this offering, there has been no public market for our common
stock. Upon completion of this offering, we will have outstanding an aggregate
of 17,302,473 shares of our common stock, assuming no exercise of the
underwriters' over-allotment option and no exercise of outstanding options. Of
these shares, all of the shares sold in this offering will be freely tradable
without restriction or further registration under the Securities Act, unless
such shares are purchased by "affiliates" as that term is defined in Rule 144
under the Securities Act. The remaining 13,302,473 shares of common stock to be
held by existing preferred stockholders will be "restricted securities" as that
term is defined in Rule 144 under the Securities Act. Restricted securities may
be sold in the public market only if registered or if they qualify for an
exemption from registration under Rule 144 or Rule 701 promulgated under the
Securities Act, which rules are summarized below.


    As a result of the lock up agreements described below and the provisions of
Rule 144, additional shares will be available for sale in the public market as
follows:


    - 2,070 shares of common stock currently outstanding will be available for
      sale into the public market following the effectiveness of this
      registration statement;



    - 2,663,589 shares of common stock issuable upon exercise of currently
      outstanding options will be eligible for sale as the options vest and
      following the effectiveness of a registration statement on Form S-8
      covering the stock options, which we expect to file shortly after the
      completion of this offering; and


    - the remainder of the restricted securities will be eligible for sale from
      time to time after the expiration of the lock up period and upon
      expiration of their respective one-year holding periods.

LOCK-UP AGREEMENTS

    All of our officers and directors and some of our stockholders are expected
to enter into lock-up agreements under which they agreed not to transfer or
otherwise dispose of, directly or indirectly, without the consent of Deutsche
Bank Securities Inc., any shares of our common stock or any securities
convertible into or exchangeable or exercisable for shares of our common stock
for a period of 180 days following the effective date of the registration
statement of which this prospectus is a part.

    Transfers or dispositions can be made during the lock-up periods in the case
of gifts for estate planning purposes where the donee signs a lock-up agreement.

RULE 144

    In general, under Rule 144 as currently in effect, beginning 90 days after
the date of this registration statement, a person who has beneficially owned
shares of our common stock for at least one year would be entitled to sell
within any three-month period a number of shares that does not exceed the
greater of:


    - 1% of the number of shares of common stock then outstanding, which will
      equal approximately 173,025 shares immediately after this offering; or


    - the average weekly trading volume of the common stock on the Nasdaq
      National Market during the four calendar weeks preceding the filing of a
      notice on Form 144 of the sale with the SEC.

    Sales under Rule 144 are also subject to manner of sale provisions and
notice requirements and to the availability of current public information about
us.

                                       62
<PAGE>
RULE 144(k)

    Under Rule 144(k), a person who is not deemed to have been one of our
affiliates at any time during the 90 days preceding a sale, and who has
beneficially owned the shares proposed to be sold for at least two years,
including the holding period of any prior owner other than an affiliate, is
entitled to sell their shares without complying with the manner of sale, public
information, volume limitation or notice provisions of Rule 144. Therefore,
unless otherwise restricted, "144(k) shares" may be sold immediately upon the
completion of this offering.

RULE 701

    In general, under Rule 701 of the Securities Act as currently in effect, any
of our employees, consultants or advisors who purchases shares from us in
connection with a compensatory stock or option plan or other written agreement
are eligible to resell their shares 90 days after the effective date of this
offering in reliance on Rule 144, but without compliance with some restrictions,
including the holding period, contained in Rule 144.

REGISTRATION RIGHTS


    After this offering, the holders of 10,482,518 shares of our common stock
and warrants exercisable for 288,056 shares of our common stock will be entitled
to demand registration of their shares under the Securities Act. All of these
holders have agreed not to demand registration of their common stock for one
year after the date of this offering. After this one year period, the holders of
a majority of the shares eligible for demand rights may require us, on not more
than two occasions, to use our best efforts to file a registration statement
under the Securities Act with respect to their shares eligible for demand rights
if the gross offering amount would be expected to exceed $20.0 million. In
addition, if at any time after this offering we propose to register any of our
securities under the Securities Act in a public offering in excess of $1.0
million, for ourselves or for other holders, we will send notice of this
registration to holders of the shares eligible for demand rights, as well as to
Mel Baiada with respect to his shares of our common stock and Silicon Valley
Bank with respect to its warrants exercisable for 9,766 shares of our common
stock. Subject to limitations and conditions set forth in the agreements
governing their registration rights, they may elect to register their eligible
shares. Further, if we propose to file a registration statement on Form S-3, a
short form registration statement, when we become eligible therefor, for an
offering in excess of $1.0 million, the holders of shares eligible for demand
rights and "piggyback" rights may register their common stock along with that
registration. We will be responsible for the expenses incurred in connection
with these registrations, other than underwriters' discounts or commissions,
except that we will pay expenses of only one registration on Form S-3 at a
holder's request per year. All registration rights expire five years from the
date of this offering.


STOCK OPTIONS


    Shortly after completion of this offering, we plan to file a registration
statement on Form S-8 under the Securities Act covering shares of common stock
reserved for issuance under our stock option and director compensation plans. As
of June 30, 1999, options to purchase 2,663,589 shares of common stock were
issued and outstanding, 1,028,050 of which are vested. This registration
statement is expected to be filed and become effective as soon as practicable

registration statement will, subject to lock-up agreements, vesting provisions
and Rule 144 volume limitations applicable to our affiliates, be available for
sale in the open market immediately after the registration statement becomes
effective.

    The underwriting agreement provides that the obligations of the underwriters
are subject to conditions precedent and that the underwriters will purchase all
of the shares of common stock offered hereby if any of such shares are
purchased.

    We have been advised by the representatives of the underwriters that the
underwriters propose to offer the shares of our common stock to the public at
the initial public offering price set forth on the cover page of this prospectus
and to certain dealers at that price less a concession not in excess of
$      per share. The underwriters may allow to some other dealers, and those
dealers may reallow, a concession not in excess of $      per share. After the
initial public offering, the offering price and other selling terms may be
changed by the representatives of the underwriters.


    We have requested that, of the 4,000,000 shares of common stock to be sold
in this offering, up to 200,000 shares be offered at the price to the public set
forth on the cover page of this prospectus to our directors, officers, employees
and business associates. Additionally, under certain circumstances, our
certificate of incorporation provides for a right of first offer to be made to
certain eligible preferred stockholders of an amount of this offering that would
enable these preferred stockholders to maintain their proportionate interest in
our capital stock after giving effect to the exercise of all outstanding
warrants and options. These preferred stockholders have the right, but not the
obligation, to acquire shares of common stock in this offering on the same terms
as the other investors. If a preferred stockholder does not accept the offer to
acquire its portion of the shares offered, its portion will be offered ratably
to the other eligible preferred stockholders. As a result, the number of shares
of common stock available for sale to the general public will be reduced to the
extent these persons purchase the reserved shares. The underwriters will offer
to the general public, on the same basis as the other shares to be sold in this
offering, any reserved shares that were not purchased.



    We and certain stockholders have granted the underwriters an option,
exercisable not later than 30 days after the date of this prospectus, to
purchase up to 600,000 additional shares of common stock at the initial public
offering price less the underwriting discounts and commissions set forth on the
cover page of this prospectus. To the extent that the underwriters exercise this
option, each of the underwriters will have a firm commitment to purchase
approximately the same percentage of the option shares that the number of shares
of common stock to be purchased by it in the above table bears to 4,000,000. The
underwriters may exercise this option only to cover over-allotments made in
connection with the sale of the common stock offered in this offering. If
purchased, the underwriters


                                       64
<PAGE>

will offer the additional shares on the same terms as those on which the
4,000,000 shares are being offered.


    We and the selling stockholders have agreed to indemnify the underwriters
against specified liabilities, including liabilities under the Securities Act.

    We have agreed not to offer, sell, sell short, transfer, hypothecate, pledge
or otherwise dispose of any shares of our common stock or other securities
convertible into or exchangeable or exercisable for shares of our common stock
or derivatives of our common stock, or enter into an agreement for our common
stock, for a period of 180 days after the date of our registration statement, of
which this prospectus is a part, directly or indirectly, by us or otherwise,
except as consideration for business acquisitions, on exercise of currently
outstanding stock options or on the issuance of options to key employees and
directors under our stock option plans and the exercise of such options, without
the prior written consent of Deutsche Bank Securities Inc.


    All of our officers and directors and certain of our stockholders intend to
enter into lock-up agreements under which they agreed not to transfer or
otherwise dispose of, directly or indirectly, without the consent of Deutsche
Bank Securities Inc. any shares of our common stock or any securities
convertible into or exchangeable or exercisable for shares of our common stock
for a period of 180 days following the date of this registration statement.


    Transfers or dispositions can be made during the lock-up periods in the case
of gifts for estate planning purposes where the donee signs a lock-up agreement.

    The representatives of the underwriters have advised us that the
underwriters do not intend to confirm sales to any account over which they
exercise discretionary authority.

    To facilitate this offering, the underwriters may engage in transactions
that stabilize, maintain or otherwise affect the market price of our common
stock. Specifically, the underwriters may over-allot shares of our common stock
in connection with this offering, creating a short position in the underwriters'
syndicate account. Additionally, to cover the over-allotments or to stabilize
the market price of our common stock, the underwriters may bid for, and
purchase, shares of our common stock in the open market. Any of these activities
may maintain the market price of our common stock at a level above that which
might otherwise prevail in the open market. The underwriters are not required to
engage in these activities and may end any of these activities at any time. The
representatives of the underwriters, on behalf of the syndicate of underwriters,
also may reclaim selling concessions allowed to an underwriter or dealer if the
syndicate repurchases shares distributed by that underwriter or dealer.


    We paid $1.4 million and issued a warrant, exercisable for five years, to
purchase up to 150,448 shares of common stock at an exercise price of $8.70 per
share to Deutsche Bank Securities Inc. for providing placement agent services to
us in connection with the offering of Series C preferred stock that was
consummated on May 25, 1999. The amount paid for these services was determined
by arms' length negotiations between us and Deutsche Bank Securities Inc. We
believe that this amount is within standard industry parameters for a
transaction of that nature. The underwriters and their respective affiliates
may, in the future, be lenders to, engage in transactions with and perform
services for us in the ordinary course of business. No transactions with the
underwriters are presently contemplated.


    Prior to this offering, there has been no public market for our common
stock. Consequently, the initial public offering price for our common stock will
be determined by negotiations between us and the representatives of the
underwriters. Among the factors to be considered in these negotiations will be
prevailing market conditions, the results of our operations in recent periods,
the market capitalizations and stages of development of other companies which we
and the representatives of the underwriters believe to be comparable to us,
estimates of our business potential, the present state of our development and
other factors deemed relevant.

Philadelphia, PA

                    REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS

To Bluestone Software, Inc.:

    We have audited the accompanying balance sheets of Bluestone Software, Inc.
(a Delaware corporation), formerly Bluestone Consulting, Inc., as of December
31, 1997 and 1998, and the related statements of operations, mandatorily
redeemable convertible preferred stock and stockholders' equity (deficit) and
cash flows for each of the three years in the period ended December 31, 1998.
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 Bluestone Software, Inc. as
of December 31, 1997 and 1998 and the results of its operations and its cash
flows for each of the three years in the period ended December 31, 1998, in
conformity with generally accepted accounting principles.

    respect to matters discussed

    date is May 25, 1999)
    and Note 13, as to
    which the date is             .)

                         NOTES TO FINANCIAL STATEMENTS


            (INFORMATION AS OF JUNE 30, 1999 AND FOR THE SIX MONTHS
                   ENDED JUNE 30, 1998 AND 1999 IS UNAUDITED)


1.  BACKGROUND:

    Bluestone Software, Inc. (the "Company"), formerly Bluestone Consulting,
Inc., was incorporated in New Jersey on March 17, 1989. The Company develops,
markets and supports web application server software products that enable its
customers to deploy information across the Internet, intranets and extranets. On
April 17, 1997, in connection with the sale of Series A Convertible Preferred
Stock (see Note 7), the Company spun off its consulting division to its then
sole stockholder for no consideration. The Company reincorporated in Delaware as
Bluestone Software, Inc. The consulting division, Bluestone Consulting, Inc.
("BCI") provides its clients information technology staffing resources and in
1997 provided the Company with certain administrative services under a shared
services agreement (see Note 11). The consulting division spin-off is reported
in the accompanying financial statements as a discontinued operation (see Note
3).

2.  LIQUIDITY:

    The Company has recurring operating losses that have continued subsequent to
year-end. The losses are primarily due to product development costs, marketing
expenditures and administrative infrastructure costs related to the expansion of
the Company's business.


    On January 21, 1999, the Company and substantially all of the Series B
Preferred stockholders (collectively, the "Investors") entered into the Note and
Warrant Purchase Agreement, whereby the Company could, from time to time before
May 30, 1999, request that the Investors purchase 10% convertible subordinated
secured notes totaling an aggregate of $5 million. Upon the purchase of a note,
the Investors would be granted a warrant to purchase the number of shares of the
Company's Common stock equal to the note amount multiplied by .1008, at an
exercise price of $1.98 per share. The Company issued warrants to purchase an
aggregate of 136,088 shares of common stock in connection with notes purchased
in April 1999 and May 1999. The Company also issued warrants to purchase an
aggregate of 1,520 shares of common stock at an exercise price of $8.70 per
share related to interest on the notes. The warrants issued in connection with
the notes and related interest thereon were valued at $1,100,000 using the
black-scholes option pricing model and the following assumptions: volatility of
70%, risk-free interest rates of 5.2% to 5.3%, fair market value of a share of
common stock of $8.70 and a term of 10 years. The value of the warrants was
charged to operations during the three months ended June 30, 1999. The notes
were converted into 496,322 shares of Series C Preferred stock on May 25, 1999
(see below).


    On March 31, 1999, the Company amended its bank loan agreement, which had
expired on February 7, 1999. The amendment extended the Company's credit
facility through April 1, 2000 and reset certain financial covenants. The
amended agreement provides for the interest rate on the credit facility to
increase by 0.50% and for certain quarterly fees to be paid if the Company does
not meet certain quarterly net revenue requirements, as defined in the
amendment.


    On May 25, 1999, the Company sold 9,191,176 shares of Series C Convertible
Preferred Stock to certain venture capital investors, including certain Series B
Preferred investors for $25 million in cash. The Series C Preferred will be
senior to the Series A Preferred and Series B Preferred and is automatically
convertible into Common stock upon a public stock offering, as defined.
Dividends on the Series C Preferred are cumulative at $0.1632 per share per
annum. The Series C Preferred stockholders participate in Common stock dividends
and have Common stock voting rights on an as converted basis.

                   NOTES TO FINANCIAL STATEMENTS (CONTINUED)


            (INFORMATION AS OF JUNE 30, 1999 AND FOR THE SIX MONTHS
                   ENDED JUNE 30, 1998 AND 1999 IS UNAUDITED)


2.  LIQUIDITY: (CONTINUED)

In conjunction with the sale of the Series C Preferred, the Company issued a
warrant to purchase 150,448 shares of common stock at $8.70 to the placement
agent, valued at $800,000 using the black-scholes option pricing model and the
following assumptions: volatility of 70%, a risk-free interest rate of 5.2%,
fair market value of a share of common stock of $8.70 and a term of 5 years. The
value of the warrant was recorded as a cost of the Series C Preferred Stock sale
and, accordingly, deducted from the proceeds of the Series C Preferred Stock.


    The Company believes that the proceeds from the sale of the Series C
Convertible Preferred Stock and borrowing availability under its amended credit
facility will provide adequate funding to sustain the Company's operations
through 1999. However, there is no assurance that the funding will be sufficient
to sustain operations until the Company begins generating positive cash flows.

3.  SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES:

INTERIM FINANCIAL STATEMENTS


    The financial statements as of June 30, 1999 and for the six months ended
June 30, 1998 and 1999 are unaudited and, in the opinion of management, include
adjustments necessary for a fair presentation of results for those interim
periods. The results of operations for the six months ended June 30, 1998 and
1999 are not necessarily indicative of the results to be expected for the entire
year.


PRO FORMA FINANCIAL INFORMATION


    The unaudited pro forma balance sheet as of June 30, 1999 reflects the
conversion of all outstanding preferred stock and all accrued preferred stock
dividends as of June 30, 1999 into common stock immediately before the
completion of the contemplated public offering.


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 certain assets and liabilities
and related disclosures at the date of the financial statements and the reported
amounts of certain revenues and expenses during the reporting periods. Actual
results could differ from these estimates.

CASH AND CASH EQUIVALENTS

    The Company considers all highly liquid investments with an original
maturity of three months or less to be cash equivalents.

PREPAID EXPENSES AND OTHER

    Prepaid expenses and other at December 31, 1997 includes $243,834 of
deferred costs related to support contracts purchased from third parties for
resale in connection with the sale of third party product.

                   ENDED JUNE 30, 1998 AND 1999 IS UNAUDITED)


3.  SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES: (CONTINUED)
PROPERTY AND EQUIPMENT


    Property and equipment are carried at cost. Depreciation is provided using
the double declining balance method over the estimated useful lives of the
related assets, generally three to seven years. Leasehold improvements are
amortized on a straight-line basis over the lease term.


PRODUCT DEVELOPMENT

    Product development expenditures are charged to operations as incurred.
Statement of Financial Accounting Standards ("SFAS") No. 86, "Accounting for the
Costs of Computer Software to be Sold, Leased or Otherwise Marketed," requires
the capitalization of certain software development costs subsequent to the
establishment of technological feasibility. The Company has determined that
technological feasibility for its products is generally achieved upon completion
of a working model. Since software development costs have not been significant
after the completion of a working model, all such costs have been charged to
product development expense.

REVENUE RECOGNITION


    The Company sells perpetual licenses to end-users and annual and multi-year
licenses primarily to independent software vendors. The Company also sells its
software through value added resellers and system integrators. The Company
derives its services revenues from annual maintenance agreements, which consist
of customer technical support services and unspecified product
upgrades/enhancements on a when-and-if-available basis, and consulting and
training services.


    License fee revenue is generally recognized when a formal agreement exists,
delivery of the product has occurred, the license fee is deemed fixed and
determinable and collectibility is probable. License revenue from arrangements
with resellers and system integrators is not recognized until the product is
delivered to end-users. Maintenance revenue is recognized on a straight-line
basis over the term of the contract. Revenues from training and consulting
services are recognized as services are performed.

    Deferred revenues generally consist of advance customer payments on
maintenance contracts. Certain of the Company's multi-year license agreements
provide for payment terms that extend beyond 12 months. Revenue on such
long-term arrangements are recognized when payments become due. Included in
accounts receivable and deferred revenues at December 31, 1998 is $1,865,294
related to an extended term license fee where the Company received payment and
recorded revenue in February 1999.

CONCENTRATION OF CREDIT RISK


    One customer accounted for approximately 11% of the Company's net revenues
for the year ended December 31, 1998 and one customer accounted for
approximately 55% of net accounts receivable at December 31, 1998. One customer
accounted for approximately 29% of net revenues for the six months ended June
30, 1999. No one customer accounted for greater than 10% of net revenues for the
years ended December 31, 1996 and 1997 or greater than 10% of net accounts
receivable at December 31, 1996 and 1997 and June 30, 1999.

3.  SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES: (CONTINUED)
ADVERTISING COSTS


    The Company expenses advertising costs as incurred. Advertising expense for
continuing operations for the years ended December 31, 1996, 1997 and 1998 and
the six months ended June 30, 1998 and 1999 was $781,634, $615,374, $882,761,
$199,910 and $793,921, respectively, including $394,808, $251,640, $549,487,
$184,094 and $307,352, respectively, related to attending trade shows.


INCOME TAXES

    Prior to April 17, 1997, the Company was taxed as a subchapter S corporation
under the Internal Revenue Code for federal and state income tax purposes.
Accordingly, all S Corporation taxable income or losses were included in the
sole stockholder's tax return. In connection with the Series A Convertible
Preferred Stock sale (see Note 7), the Company's subchapter S election was
terminated.

    Deferred tax assets and liabilities are determined based on differences
between the financial reporting and tax bases of assets and liabilities and are
measured using enacted tax rates. The Company accounts for certain income and
expense items for financial reporting purposes differently than for income tax
purposes. The principal differences relate to the Company's conversion to the
accrual basis of accounting for income taxes and certain financial statement
reserves that are not currently deductible for income tax purposes.

STOCK COMPENSATION

    The Company has elected to follow Accounting Principles Board ("APB")
Opinion No. 25, "Accounting for Stock Issued to Employees," and related
interpretations in accounting for its employee stock options. Under APB No. 25,
if the exercise price of the Company's employee stock options equals or exceeds
the market price of the underlying stock on the date of the grant, no
compensation expense is recognized. If the exercise price of an option is below
the market price of the underlying stock on the date of grant, compensation cost
is recorded and is recognized in the statements of operations over the vesting
period (see Note 9).

EARNINGS PER SHARE


    The Company follows SFAS No. 128, "Earnings Per Share," which requires a
dual presentation of "basic" and "diluted" earnings per share ("EPS") on the
face of the statements of operations. Basic EPS is computed by dividing net
income (loss) by the weighted average number of shares of common stock
outstanding for the period. Diluted EPS includes the dilutive effect, if any,
from the potential exercise or conversion of securities like stock options,
which would result in the issuance of additional shares of common stock. For
each of the three years in the period ended December 31, 1998 and the six months
ended June 30, 1998 and 1999, the impact of stock options was not considered as
their effect on EPS would be anti-dilutive.


FAIR VALUE OF FINANCIAL INSTRUMENTS

    Cash, accounts receivable, prepaid expenses, accounts payable and accrued
expenses are reflected in the accompanying financial statements at fair value
due to the short-term nature of those

instruments. The carrying amount of long-term debt obligations approximate fair
value at the balance sheet dates.

RECENT ACCOUNTING PRONOUNCEMENTS

    In June 1997, the Financial Accounting Standards Board issued SFAS No. 130,
"Reporting Comprehensive Income." SFAS No. 130 is effective for fiscal years
beginning December 31. 1997, SFAS No. 130 establishes standards for the
reporting and display of comprehensive income in a set of financial statements.
Comprehensive income is defined as the change in net assets of a business
enterprise during a period from transactions generated from non-owner sources.
It includes all changes in equity during a period except those resulting from
investments by owners and distributions to owners. The Company has no other
comprehensive income items, therefore, the adoption of SFAS No. 130 had no
impact on the financial statements.

    In June 1997, the Financial Accounting Standards Board issued SFAS No. 131,
"Disclosures about Segments of an Enterprise and Related Information." SFAS No.
131 applies to all public companies and is effective for fiscal years beginning
after December 15, 1997. SFAS No. 131 requires that business segment financial
information be reported in the financial statements utilizing the management
approach. The management approach is defined as the manner in which management
organizes the segments within the enterprise for making operating decisions and
assessing performance. Subsequent to the spin-off of the consulting segment,
management believes the Company operates in one business segment, therefore, the
adoption of SFAS No. 131 had no impact on the financial statements.

    In March 1998, the American Institute of Certified Public Accountants issued
Statement of Position ("SOP") 98-1, "Accounting for the Costs of Computer
Software Developed or Obtained for Internal Use." The Company adopted SOP 98-1
in January 1999. The adoption had no material effect on the Company's financial
position or results of operations.

DISCONTINUED OPERATIONS


    On April 17, 1997, in connection with the sale of Series A Convertible
Preferred Stock (see Note 7), the Company spun off its consulting division,
which operated as a separate segment, to its then sole stockholder for no
consideration. The spin-off, which included cash of $274,538, has been recorded
as a deemed distribution in the accompanying financial statements. The
discontinued operation generated net revenues of $13,369,459 and $4,537,147 for
the years ended December 31, 1996 and 1997, respectively. The spin-off was
treated as a tax-free reorganization for federal and state income tax purposes.


RECLASSIFICATIONS

    Prior year financial statements have been reclassified to conform with the
current year presentation.

4.  LINE OF CREDIT:

    On December 8, 1997, the Company entered into an agreement with a bank that
provides for a $1,750,000 revolving line of credit and a $500,000 equipment line
(see Note 5). The revolver is collateralized by substantially all of the
Company's assets and a $400,000 certificate of deposit at December 31, 1997.
Borrowings under the line are subject to a borrowing base of 80% of eligible
accounts receivable, as defined. The restricted certificate of deposit was sold
in 1998 as it was no longer required collateral. The line bore interest at prime
plus 1.5%, through August 16, 1998 at which date the interest rate was changed
to prime plus .75% in conjunction with the equipment line modification (see Note
5), and expired on December 7, 1998. In December 1998, the Company and the bank
agreed to extended the term of the credit facility to February 7, 1999. The line
is cross-defaulted and cross-collateralized with the equipment line with the
bank (see Note 5). The loan agreement also requires the Company to maintain
certain financial and nonfinancial covenants, as defined.


    On March 31, 1999, the Company amended its bank loan agreement. The
amendment extended the Company's credit facility through April 1, 2000 and reset
certain financial covenants. The amended agreement provides for the interest
rate on the credit facility to increase to prime plus 1.25% and for certain
quarterly fees to be paid if the Company does not meet certain quarterly net
revenue requirements, as defined in the amendment. At June 30, 1999, borrowings
of $1,023,463 were available under the line.



    A warrant to purchase 9,766 shares of the Company's Common stock at $2.56
per share, as adjusted was issued to the bank in December 1997 in conjunction
with the loan agreement. The warrant is fully exercisable, has a seven-year term
and is subject to an anti-dilution provision, as defined. No value has been
assigned to the warrant as it is not material to the Company's financial
statements.

    The options under the 1996 Plan generally vest over a four year period. At
June 30, 1999 there were options to purchase 1,028,050 shares of common stock
exercisable and options to purchase 275,534 shares of common stock were
available for future grant under the 1996 Plan. The weighted average remaining
contractual life of the outstanding options at June 30, 1999 was 9.23 years.



    In connection with certain options granted to employees during the six
months ended June 30, 1999, the Company recorded $1,415,548 of deferred
compensation. This amount represents the difference between the fair market
value of the Company's common stock on the date of grant and the exercise price
of options to purchase 284,313 shares of the Company's common stock. Deferred
compensation is amortized over the vesting periods of the options, which range
from immediate vesting to periods of up to four years. For the six months ended
June 30, 1999 $112,204 of deferred compensation was charged to expense. At June
30, 1999, the Company had $1,303,344 of deferred compensation to be amortized
over the remaining vesting periods of four years.



    Included in options granted below fair market value during the six months
ended June 30, 1999 are options to purchase 25,000 shares of common stock issued
to non-employees for consulting services. The Company recorded $190,954 in
general and administrative expenses during the six months ended June 30, 1999
related to these options.



    In 1999 the Company established an executive bonus pool for issuance of
common stock options to the Chairman and to certain officers of the Company
under the 1996 Plan. Grants of stock option awards under the bonus pool are
contingent upon the Company meeting certain performance goals.

9.  STOCK OPTION AND EMPLOYEE BENEFIT PLANS: (CONTINUED)

The Company granted 52,650 options relating to the bonus pool in May 1999 for
the Company's operating results during the three months ended March 31, 1999. In
August 1999 the Company will grant 60,259 options relating to the bonus pool for
the Company's operating results for the three months ended 6/30/99. Options
granted in connection with the bonus pool vest immediately.



    In June 1999, the Company adopted the Directors' Compensation Plan under
which non-qualified options to acquire shares of the Company's common stock may
be granted to non-employee directors of the Company. Options granted under the
Directors Compensation Plan vest immediately and are exercisable over a period
of time not to exceed five years. The total number of shares available under the
Directors Compensation Plan is 156,250.


    The Company applies Accounting Principles Board Opinion No. 25, "Accounting
for Stock Issued to Employees," and the related interpretations, in accounting
for its stock option plan. Had compensation cost for the 1996 Plan been
determined based upon the fair value of the options at the date of grant, as
prescribed under SFAS 123, the Company's net loss for the years ended December
31, 1997 and 1998 would have increased to the following pro forma amount:

    The Company has established a valuation allowance for the full amount of the
net deferred tax asset due to the limited operating history of the Company and
uncertainty surrounding realizability. At December 31, 1998, the Company had a
net operating loss carryforward of approximately $14 million beginning to expire
in 2012 for federal tax purposes and in 2004 for state tax purposes.

11.  TRANSACTIONS WITH BCI:

    On April 17, 1997, in connection with the sale of the Series A Convertible
Preferred Stock (see Note 7), the Company spun off its consulting division, BCI,
to its then sole stockholder, who is currently a director of the Company.


    In connection with the spin-off, the Company entered into the Intercompany
Services Agreement with BCI, whereby BCI provided the Company certain
administrative services at an allocated cost based on actual cost and usage. For
the year ended December 31, 1997, general and administrative expense includes
$871,784 for such services provided by BCI.



    The Company also sells certain software products and services to BCI and
purchases certain consulting services from BCI. For the years ended December 31,
1997 and 1998 and for the six months ended June 30, 1998 and 1999, the Company's
sales to BCI totaled $40,448, $58,607, $28,582 and

    On March 31, 1998, the Company decided to no longer sell non-proprietary
software products. In addition, the Company agreed to allow BCI to commence the
sale and support of this product line, and sub-contracted support services to
BCI related to previously sold maintenance contracts. The Company paid BCI
$450,000 in 1998 and paid BCI $150,000 in 1999, for the sub-contracted support
services.


    The Company also sub-leases a portion of its operating facility to BCI (see

the years ended December 31, 1997 and 1998 and the six months ended June 30,
1998 and 1999, totaled $130,588, $74,165, $28,586 and $46,949, respectively.

$39,845 and $49,510, respectively.


    In connection with the Series A Convertible Preferred Stock sale and

results of operations.

13.  PUBLIC OFFERING SUBSEQUENT TO DECEMBER 31, 1998:



    On June 10, 1999, the Company's Board of Directors authorized management to
file a Registration Statement with the SEC to permit the Company to commence an
initial public offering. In connection therewith, on August 13, 1999, the
Company's Board of Directors authorized a 1-for-3.2 reverse split of its common
stock to be effected immediately prior to the offering. The reverse stock split
has been retroactively reflected in the accompanying financial statements.


                                      F-18

After the 1-for-3.2 reverse stock split of each outstanding share of common
stock, as discussed in Note 13 to the financial statements, is effected, we
expect to be in a position to render the following audit report.

ITEM 14. INDEMNIFICATION OF DIRECTORS AND OFFICERS.

    Section 145 of the Delaware General Corporation Law permits each Delaware
business corporation to indemnify its directors, officers, employees and agents
against liability for each such person's acts taken in his or her capacity as a
director, officer, employee or agent of the corporation if such actions were
taken in good faith and in a manner which he or she reasonably believed to be in
or not opposed to the best interests of the corporation, and with respect to any
criminal action, if he or she had no reasonable cause to believe his or her
conduct was unlawful. Section 23.1 of Bluestone's bylaws provides that
Bluestone, to the full extent permitted by Section 145 of the Delaware General
Corporation Law, shall indemnify all past and present directors, officers,
employees and agents of Bluestone who were or are parties or are threatened to
be made parties to or are involved in any action, suit or proceeding against all
expenses, liability and losses in connection with such proceeding. Such expenses
may be paid by Bluestone in advance of the final disposition of the action upon
receipt of an undertaking to repay the advance if it is ultimately determined
that such person is not entitled to indemnification.

    As permitted by Section 102(b)(7) of the Delaware General Corporation Law,
Article VIII of Bluestone's certificate of incorporation provides that no
director of Bluestone shall be liable to Bluestone for monetary damages for
breach of fiduciary duty as a director, except for liability (i) for any breach
of the director's duty of loyalty to Bluestone or its stockholders, (ii) for
acts or omissions not in good faith or which involve intentional misconduct or a
knowing violation of law, (iii) for the unlawful payment of dividends on or
redemption of Bluestone's capital stock, or (iv) for any transaction from which
the director derived an improper personal benefit.

    Bluestone has obtained a policy insuring it and its directors and officers
against certain liabilities, including liabilities under the Securities Act.

    It is anticipated that the Underwriting Agreement to be filed as Exhibit 1.1
to this Registration Statement will provide for indemnification by the
Underwriters of the Registrant and its officers and directors for certain
liabilities arising under the Securities Act or otherwise.

ITEM 15. RECENT SALES OF UNREGISTERED SECURITIES

    During the past three years, the Registrant has sold the securities set
forth below which were not registered under the Securities Act:


    Pursuant to a stock purchase agreement dated April 18, 1997, the Registrant
issued 5,526,316 shares of Series A preferred stock to institutional and
accredited investors for a total purchase price of $5.25 million or $0.95 per
share, including 263,158 shares of Series A preferred stock to Mel Baiada. No
underwriters were used for such offering.


                                      II-1
<PAGE>

    In connection with the Registrant's credit facility with Silicon Valley
Bank, the Registrant issued to Silicon Valley Bank a warrant dated November 24,
1997 to purchase up to 9,766 shares of common stock at an exercise price equal
to $2.56 per share. The warrant may be exercised at any time prior to November
24, 2004. The exercise price of the warrant and the number of shares of common
stock into which the warrant is exercisable are subject to proportionate
adjustment in the event of stock dividends payable in shares of common stock and
combinations and splits of common stock. In addition, pursuant to an
antidilution agreement between the Registrant and Silicon Valley Bank dated
November 24, 1997, the exercise price of the warrant and the number of shares of
common stock into which the warrant is exercisable are subject to adjustment on
a broad-based weighted average basis for issuance of securities after November
24, 1997 for less than the then applicable exercise price for the warrant.



    Pursuant to a stock purchase agreement dated April 22, 1998, the Registrant
issued 8,782,695 shares of Series B preferred stock to institutional and
accredited investors for a total purchase price of $11.4 million or $1.296 per
share.



    On January 21, 1999, the Registrant entered into the Note and Warrant
Purchase Agreement with substantially all of the holders of the Series B
preferred stock (the "Investors"). Under the Note and Warrant Purchase
Agreement, the Investors agreed to provide subordinated secured debt financing
of up to $5.0 million (the "Committed Principal Amount"). The Registrant drew
down $1.35 million of such debt and issued 10% Convertible Subordinated Secured
Notes and warrants to purchase up to 136,088 shares of common stock at an
exercise price equal to $1.98 per share to the Investors. The outstanding $1.35
million of the Committed Principal Amount was converted into Series C preferred
stock as part of our issuance of 9,191,176 shares of Series C preferred stock at
$2.72 per share on May 25, 1999.



    Pursuant to a stock purchase agreement dated May 25, 1999, the Registrant
issued 9,191,176 shares of Series C preferred stock to institutional and
accredited investors for a total purchase price of $25.0 million, or $2.72 per
share. Deutsche Bank Securities Inc. acted as the placement agent for such
offering for which it received $1.4 million and a warrant to purchase up to
150,448 shares of common stock at $8.70 per share.



    From March 1, 1996 to June 30, 1999, the Registrant granted stock options to
purchase 3,062,177 shares of common stock at exercise prices ranging from $2.24
to $8.70 per share to employees, consultants and directores pursuant to its
Amended and Restated 1996 Incentive and Non-Qualified Stock Option Plan.



    Between March 1998 and June 1999, 7,455 shares of common stock of the
Registrant have been issued to current and former employees pursuant to the
exercise of stock options.



    The Registrant believes that all grants of options or sales of common stock
made pursuant to the exercise of stock options were made in reliance upon Rule
701 under the Securities Act or on Section 4(2) of the Securities Act. The
Registrant believes that all of the other transactions described above were
exempt from registration under Section 3(b) or 4(2) of the Securities Act
because the subject securities were sold to a limited group of persons, each of
whom was believed to have been a sophisticated, accredited investor or to have
had a pre-existing business or personal relationship with the Registrant or its
management and to have been purchasing for investment without a view to further
distribution. In addition, the recipients of securities in each such transaction
represented their intentions to acquire the securities for investment only and
not with a view to or for sale in connection with any distribution thereof and
appropriate legends were affixed to the share certificates issued in such
transactions. All recipients had adequate access to information about the
Registrant.

ITEM 17. UNDERTAKINGS

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

    (b) 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

                                      II-5
<PAGE>
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.

    (c) The Registrant hereby undertakes that:

        (i) For purposes of determining any liability under the Securities Act,
    the information omitted from the form of prospectus filed as part of this
    Registration Statement in reliance upon Rule 430A and contained in the form
    of prospectus filed by the Registrant pursuant to Rule 424(b)(1) or (4) or
    497(h) under the Securities Act shall be deemed to be part of the
    Registration Statement as of the time it was declared effective.

        (ii) For purposes of determining any liability under the Securities Act,
    each post-effective amendment that contains a form of prospectus shall be
    deemed to be a new registration statement relating to the securities offered
    therein, and the offering of such securities at that time shall be deemed to
    be the initial bona fide offering thereof.

affecting the administration of the Plan or the grant of any Options pursuant to

<PAGE>

behalf of the Board, subject to the terms and conditions as the Board may
prescribe. Members of the Committee may or may not be members of the Board and
shall serve for such period of time as the Board may determine. From time to
time, the Board may increase the size of the Committee and appoint additional
members thereto, remove members (with or without cause) and appoint new members
in substitution therefor, fill vacancies however caused, or remove all members
of the Committee and thereafter directly administer the Plan.

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

                           (i) to determine whether and to what extent Options
are granted hereunder;

                           (vii) to determine the terms and provisions of each
Option granted under the Plan, each Option Agreement and each other agreement
that in the sole discretion of the Administrator may be required (all of which
agreements need not be identical with the terms of other Options, Option
Agreements or other agreements);

                           (viii) to determine the circumstances under which the
vesting or exercise date of an Option will be accelerated;

                           (ix) to interpret the Plan or any agreement entered
into with respect to the grant or exercise of Options;

                           (x) to authorize any person to execute on behalf of

                                       -6-
<PAGE>

                           (xi) to determine whether and under what
circumstances an Option may be exercised without a payment of cash under Section
6(c) hereof;

                           (xii) to terminate the Plan in the event of a Change
of Control;

                           (xiii) to determine whether or not a Transfer has
occurred; and

                           (xiv) to make such other determinations and establish
such other procedures as it deems necessary or advisable for the administration
of the Plan.

                  (d) EFFECT OF THE ADMINISTRATOR'S DECISION. All decisions,
determinations and interpretations of the Administrator pursuant to the
provisions of the Plan shall be final and binding on all Optionees and any other
holders of Options.

                  (e) LIMITATION OF LIABILITY. Notwithstanding anything herein
to the contrary, no member of the Board or the Committee shall be liable for any
good faith determination, act or failure to act in connection with the Plan or
any Option awarded hereunder.

                  Section 4.  ELIGIBILITY.

                  (a) ELIGIBLE PERSONS. Options may be granted at any time and
from time to time to any Employee or Consultant who shall be selected by the
Administrator. Any grant of Options may include or exclude any Employee or
Consultant as the Administrator shall determine in its sole discretion.
Consultants who are not also Employees of the Company are eligible to be granted
Non-Qualified Stock Options under the Plan but are not eligible to be granted
Incentive Stock Options under the Plan.

                  (b) VESTING OF OPTIONS. Subject to the provisions of Section 6
hereof and except to the extent the Board provides otherwise, each Option shall
vest at a rate of twenty-five percent (25%) of the Shares subject to the Option
per year (the total number of Shares so vested being the "Vested Amount") during
the consecutive four (4) year period commencing on the date of grant. Options
that are not vested may not be exercised.

                  (c) EFFECT UPON ENGAGEMENT. The Plan will not confer upon any
Optionee any right with respect to the continuation of any employment,
consulting or any other relationship with the Company or BCI nor will it
interfere in any way with such Optionee's right or the Company's or BCI's right
to terminate that Optionee's employment, consulting or other relationship with
the Company or BCI at any time, whether with or without cause.

                  Section 5.  STOCK SUBJECT TO THE PLAN.

                  (a) MAXIMUM NUMBER OF SHARES. Subject to the provisions of
Section 8 of the Plan, the maximum aggregate number of Shares which may be
optioned and sold under the Plan is Ten Million Five Hundred Twenty Nine
Thousand Forty Nine (10,529,049) Shares. The Shares may be authorized, but
unissued or reacquired, Common Stock. Notwithstanding the

                                       -7-
<PAGE>

foregoing, no individual shall receive, over the term of the Plan, awards for
more than an aggregate of Ten Million Five Hundred Twenty-Nine Thousand
Forty-Nine (10,529,049) Shares authorized for grant under the Plan.

                  (b) RETURN OF SHARES TO THE PLAN. If an Option expires, is
terminated or become unexercisable for any reason without having been exercised
in full, then the unpurchased Shares subject thereto shall, unless the Plan
shall have been terminated, return to the Plan and become available for future
grant under the Plan.

                  Section 6.  TERMS AND CONDITIONS OF OPTIONS.

                  Each Option granted under the Plan shall be authorized by the
Board and shall be evidenced by an Option Agreement which shall state or
incorporate by reference all other terms and conditions of the Plan including,
without limitation, the following terms and conditions:

                  (a) NUMBER OF SHARES. The Option Agreement shall state the
number of Shares subject to the Option.

                  (b) OPTION EXERCISE PRICE. The per Share exercise price for
the Shares to be issued pursuant to the exercise of an Incentive Stock Option
shall be stated in the Option Agreement and shall be no less than the Fair
Market Value per share of the Common Stock on the date such Option is granted,
without regard to any restriction other than a restriction that by its terms
will never lapse; provided, however, that any Incentive Stock Option granted
under this Plan to an Employee who, at the time such Option is granted, owns
more than ten percent (10%) of the current total combined voting power of all
classes of the capital stock of the Company, shall have an exercise price per
Share of not less than one hundred ten percent (110%) of the Fair Market Value
of the Common Stock on the date such Option is granted. The per Share exercise
price for the Shares to be issued pursuant to the exercise of a Non-Qualified
Stock Option shall be stated in the Option Agreement and shall be determined by
the Administrator but shall be at least $.01 per Share.

                  (c) CONSIDERATION. The consideration to be paid for the Shares
to be issued upon the exercise of an Option, including the method of payment,
shall be determined by the Administrator and may consist entirely of: (i) cash;
(ii) check; (iii) authorization from the Company to retain from the total number
of Shares as to which the Option is exercised that number of Shares having a
Fair Market Value on the date of exercise equal to the exercise price for the
total Shares as to which the Option is exercised; (iv) to the extent permitted
under the Exchange Act, the delivery of a properly executed exercise notice
together with irrevocable instructions to a Securities Broker to promptly
deliver to the Company the amount of sale or loan proceeds required to pay the
exercise price; or (v) such other consideration and method of payment as the
Administrator may from time to time determine. In making its determination as to
the type of consideration to accept, the Administrator shall consider if the
acceptance of such consideration may be reasonably expected to benefit the
Company.

                                      -8-
<PAGE>

                  (d) FORM OF OPTION. The Option Agreement shall state whether
the Option granted thereunder is intended to be an Incentive Stock Option or a
Non-Qualified Stock Option and shall, subject to the terms of the Option
Agreement, constitute a binding determination as to the form of Option granted
thereunder.

                  (e) EXERCISE OF AN OPTION.

                           (i) Unless otherwise provided by the Board, any
Option granted hereunder shall be exercisable, in whole or in part, in
accordance with the vesting schedule set forth in Section 4(b) hereof and shall
be exercisable at such times and under such further conditions as may be
determined by the Board and as set forth in the Option Agreement.

                           (ii) An Option may not be exercised for a fraction of
a Share. In the event of a "cashless exercise" as permitted under Section 6(c)
hereof, the Company shall issue shares for, the whole number of shares acquired
through such cashless exercise and cash for the value of any fractional share.

                           (iii) An Option may not be exercised after the date
of expiration of its term as shall be set forth in the Option Agreement.

                           (iv) An Option shall be deemed to be exercised when
written notice of such exercise has been received by the Company at its
principal executive office in accordance with the terms of the Option Agreement
by the person entitled to exercise the Option, and full payment for the Shares
with respect to which the Option is exercised has been received by the Company,
accompanied by an executed Stock Purchase and Restriction Agreement and any
other agreements required by the Administrator or the terms of the Plan and/or
Option Agreement. An Optionee shall have no right to vote or receive dividends
and shall have no other rights as a stockholder with respect to the Shares,
notwithstanding the exercise of the Option, until the issuance (as evidenced by
the appropriate entry on the books of the Company or of a duly authorized
transfer agent of the Company) of the stock certificate evidencing such Shares.
No adjustment shall be made for a dividend or other right for which the record
date is prior to the date a stock certificate with respect to the Shares is
issued.

                           (v) As soon as practicable after the proper exercise
of an Option in accordance with the provisions of the Plan, the Company shall,
without transfer or issue tax to the Optionee, deliver to the Optionee at the
principal executive office of the Company or such other place as shall be
mutually agreed upon between the Company and the Optionee, a certificate or
certificates representing the Shares for which the Option shall have been
exercised. The time of issuance and delivery of the certificate(s) representing
the Shares for which the Option shall have been exercised may be postponed by
the Company for such period as may be required by the Company, with reasonable
diligence, to comply with any applicable listing requirements of any national or
regional securities exchange or any law or regulation applicable to the issuance
or delivery of such Shares.

                                      -9-
<PAGE>

                           (vi) The exercise of an Option in any manner shall
result in a decrease in the number of Shares that thereafter may be available
both for purposes of the Plan and for sale under the Option by the number of
Shares as to which the Option is exercised.

                  (f)      TERMINATION OF OPTIONS.

                           (i) TERMINATION IN GENERAL. Unless sooner terminated
as provided in this Plan, each Option shall be exercisable for the period of
time as shall be determined by the Administrator and set forth in the Option
Agreement and shall be void and unexercisable thereafter.

                           (ii) TERMINATION OF RELATIONSHIP WITH THE COMPANY.
Unless sooner terminated as provided in this Plan, in the event of the
termination of an Optionee's employment or consulting relationship with the
Company (as the case may be), including termination of employment or consulting
relationship with BCI, for any reason other than the death or Disability of the
Optionee, such Optionee may, within three (3) months (or such other period of
time as is determined by the Board) from the date of such termination (but in no
event later than the expiration date of the term of such Option as set forth in
the Option Agreement), exercise the Option up to the Vested Amount as of the
date of termination provided that the Optionee was entitled to exercise the
Option on the date of such termination; provided, however, that an Optionee who
has Transferred shall not be considered to have terminated his relationship with
the Company. To the extent the Optionee was not entitled to exercise the Option
on the date of such termination, or if the Optionee does not exercise such
Option to the extent so entitled within the time specified herein, the Option
will terminate.

                           (iii) DEATH OR DISABILITY. Unless sooner terminated
as provided in this Plan, in the event of the death or Disability of an Optionee
while employed or engaged by the Company (as the case may be), including
termination of employment or service with BCI, due to death or Disability,
Options held by such Optionee that are exercisable on the date of Disability or
death shall be exercisable up to the Vested Amount as of the date of Disability
or death for a period of twelve (12) months commencing on the date of the
Optionee's Disability or death. Such Options may be exercisable by the Optionee
or his or her legal guardian or representative or, in the case of death, by his
or her executor(s) or administrator(s); provided, however, if such disabled
Optionee shall commence any employment or engagement during such twelve (12)
month period with or by a competitor of the Company (INCLUDING, but not limited
to, full or part-time employment or independent consulting work, but EXCLUDING
any employment or engagement by BCI), as determined solely in the judgment of
the Administrator, then all Options held by such Optionee that have not yet been
exercised shall terminate immediately upon the commencement thereof.

                           (iv) AGREEMENT TO TERMINATE. Options may be
terminated at any time by agreement between the Company and the Optionee.

                  (g)  OTHER PROVISIONS.

                           (i) Notwithstanding any provision in this Plan or an
Option Agreement to the contrary, no Option granted to any Optionee under this
Plan shall be treated as an Incentive Stock Option to the extent that such
Option would cause the aggregate Fair Market Value of all Shares with respect to
which Incentive Stock Options are exercisable by such Optionee for the first
time during any calendar year (determined as of the date of grant of each such
Option) to exceed $100,000. For purposes of determining whether an Incentive
Stock Option granted to an Optionee would cause the aggregate Fair Market Value
to exceed the $100,000 limitation, such Incentive Stock Options shall be taken
into account in the order granted. For purposes of this subsection, Incentive
Stock Options granted to an Optionee shall include all incentive stock options
under all plans of the Company that are incentive stock option plans within the
meaning of Section 422 of the Code. Options may be exercised in any order
elected by the Optionee, whether or not the Optionee holds any unexercised
Options under this Plan or any other plan of the Company.

                           (ii) Notwithstanding any other provision of this Plan
or an Option Agreement to the contrary, no Option shall be (A) granted under
this Plan after ten (10) years from the date on which this Plan is adopted by
the Board, or (B) exercisable more than ten (10) years from the date of grant;
provided that if an Incentive Stock Option shall be granted under this Plan to
any Employee who, at the time of the grant of such Option, owns stock possessing
more than ten percent (10%) of the total combined voting power for all classes
of the Company's capital stock, the foregoing clause (B) shall be deemed
modified by substituting the term "five (5) years" for the term "ten (10) years"
that appears therein.

                  Section 7. FAIR MARKET VALUE OF COMMON STOCK.

                  The Fair Market Value of a Share of Common Stock, as of any
date, shall be determined as follows:

                  (a) If the Shares of Common Stock are listed on a national or
regional securities exchange or traded through NASDAQ/NMS, then the Fair Market
Value of a share of Common Stock shall be the closing price for a share of
Common Stock on the exchange or on NASDAQ/NMS, as reported in THE WALL STREET
JOURNAL or such other source as the Administrator deems reliable on the relevant
valuation date, or if there is no trading on that date, on the next trading
date.

                  (b) If the Shares of Common Stock are traded in the
over-the-counter market, then the Fair Market Value of a share of Common Stock
shall be the mean of the bid and asked prices for a share of Common Stock on the
relevant valuation date as reported in THE WALL STREET JOURNAL or other source
the Administrator deems reliable (or, if not so reported, as otherwise reported
by the National Association of Securities Dealers Automated Quotations
("NASDAQ") System or the NASD OTC Bulletin Board), or if there is no trading on
such date, on the next trading date.

                  (c) In the absence of an established market for the Common
Stock, the Fair Market Value of a share of Common Stock shall be determined by
the Board in its sole discretion.

                  Section 8.  ADJUSTMENTS.

                  (a) ADJUSTMENTS. Subject to any required action by the
stockholders of the Company, the number of Shares covered by each outstanding
Option, the number of Shares that have been authorized for issuance under the
Plan but as to which no Options have yet been granted or that have been returned
to the Plan upon cancellation or expiration of an Option, and the price per
Share of the Common Stock covered by an Option will each be proportionately
adjusted for any increase or decrease in the number of outstanding shares of
Common Stock resulting from stock splits, reverse stock splits, stock dividends,
reclassifications and recapitalizations. Such adjustment shall be made by the
Board whose determination in that respect will be final, binding and conclusive.
Except as provided herein, no issuance by the Company of shares of stock of any
class or securities convertible into shares of stock of any class, will affect,
and no adjustment by reason thereof will be made with respect to, the number or
price of shares of Common Stock subject to an Option.

                  (b) NO FRACTIONAL SHARES. No fractional Shares shall be
issuable on account of any action aforesaid, and the aggregate number of Shares
into which Shares then covered by the Option, when changed as the result of such
action, shall be reduced to the number of whole Shares resulting from such
action, unless the Board, in its sole discretion, shall determine to issue scrip
certificates in respect to any fractional Shares, which scrip certificates shall
be in a form and have such terms and conditions as the Board in its discretion
shall prescribe.

                  Section 9.  RIGHTS AS A STOCKHOLDER.

                  An Optionee shall have no rights as a stockholder of the
Company and shall not have the right to vote nor receive dividends with respect
to any Shares subject to an Option until such Option has been exercised and a
stock certificate with respect to the Shares purchased upon such exercise of the
Option has been issued to Optionee as set forth in Section 6(e)(iv) and (v)
hereof.

                  Section 10.  FORFEITURE.

                  Notwithstanding any other provision of this Plan, if an
Optionee's employment or consulting relationship with the Company (as the case
may be) is terminated by the Company or BCI and the Board makes a determination
that the Optionee (i) has engaged in any type of disloyalty to the Company or
BCI, including without limitation, fraud, embezzlement, theft, or dishonesty in
the course of Optionee's employment or consulting relationship, (ii) has been
convicted of a felony or other crime involving a breach of trust or fiduciary
duty owed to the Company or BCI, (iii) has made an unauthorized disclosure of
trade secrets or confidential information of the Company or BCI, or (iv) has
breached any confidentiality agreement or non-competition agreement with the
Company or BCI in any material respect, then, at the election of


                                      -12-
<PAGE>


the Board, all unexercised Options held by the Optionee (whether or not then
exercisable) shall terminate. In the event of such an election by the Board, in
addition to immediate termination of all unexercised Options, the Optionee shall
forfeit all Shares for which the Company has not yet delivered stock
certificates to the Optionee and the Company shall refund to the Optionee the
exercise price paid to it upon exercise of the Option with respect to such
Shares. Notwithstanding anything herein to the contrary, the Company may
withhold delivery of stock certificates pending the resolution of any inquiry
that could lead to a finding resulting in forfeiture.

                  Section 11.  TIME OF GRANTING OPTIONS.

                  The date of grant of an Option shall, for all purposes, be the
date on which the Administrator makes the determination to grant the Option or
such other date as is determined by the Administrator. Notice of the
determination shall be given to each Optionee to whom an Option is so granted
within a reasonable time after the date of such grant.

                  Section 12. MODIFICATION, EXTENSION, RENEWAL OF OPTION.

                  Subject to the terms and conditions of the Plan, the Board may
modify, extend or renew an Option, or accept the surrender of an Option (to the
extent not theretofore exercised); provided that no Incentive Stock Option may
be modified, extended or renewed if such action would cause such Option to cease
to be an "incentive stock option" within the meaning of Section 422 of the Code.

                  Section 13.  TRANSFERABILITY.

                  No Option may be sold, pledged, assigned, transferred or
disposed of in any manner other than by will or by the laws of descent and
distribution. During the lifetime of the Optionee, his or her Options shall be
exercisable only by the Optionee, or, in the event of his or her legal
incapacity or Disability, by the legal guardian or representative of the
Optionee.

                  Section 14.  POWER OF BOARD IF CHANGE OF CONTROL.

                  Notwithstanding anything to the contrary set forth in this
Plan, in the event of a Sale of the Company, fifty percent (50%) of all Options
that have not vested as of the date of a Sale of the Company shall become
immediately vested and exercisable. All remaining unvested Options shall vest in
accordance with the vesting schedule set forth in the applicable Option
Agreement. Notwithstanding the preceding, the Board shall have the right, in its
sole discretion, to accelerate the vesting of all Options that have not vested
as of the date of the Change of Control and/or to establish an earlier date for
the expiration of the exercise of an Option (notwithstanding a later expiration
of exercisability set forth in an Option Agreement). In addition, in the event
of a Change of Control of the Company, the Board shall have the right, in its
sole discretion, subject to and conditioned upon a Sale of the Company: (i) to
arrange for the successor company (or other entity) to assume all of the rights
and obligations of the Company under this Plan; or (ii) to terminate this Plan
and (A) to pay to all Optionees cash with respect to

                                      -13-
<PAGE>

those Options that are vested as of the date of the Sale of the Company in an
amount equal to the difference between the Option Price and the Fair Market
Value of a Share of Common Stock (determined as of the date the Plan is
terminated) multiplied by the number of Options that are vested as of the date
of the Sale of the Company which are held by the Optionee as of the date of the
Sale of the Company, or (B) to arrange for the exchange of all Options for
options to purchase common stock in the successor corporation, or (C) to
distribute to each Optionee other property in an amount equal to and in the same
form as the Optionee would have received from the successor corporation if the
Optionee had owned the Shares subject to Options that are vested as of the date
of the Sale of the Company rather than the Option at the time of the Sale of the
Company. The form of payment or distribution to the Optionee pursuant to this
Section shall be determined by the Board in its sole discretion.

                  Section 15.  AMENDMENT OR TERMINATION OF THE PLAN.

                  Insofar as permitted by law and the Plan, the Board may at any
time suspend, terminate, discontinue, alter or amend the Plan in any respect
whatsoever; provided, however, that without prior approval of at least a
majority of the stockholders entitled to vote thereon, no such revision or
amendment may change the aggregate number of Shares for which Options may be
granted hereunder, change the designation of the class of Optionees eligible to
receive Options or decrease the price at which Options may be granted. Any other
provision of this Section notwithstanding, the Board specifically is authorized
to adopt any amendment to this Plan deemed by the Board to be necessary or
advisable to assure that the Incentive Stock Options or the Non-Qualified Stock
Options available under the Plan continue to be treated as such, respectively,
under all applicable laws.

                  Section 16.  APPLICATION OF FUNDS.

                  The proceeds received by the Company from the sale of Shares
pursuant to the exercise of Options shall be used for general corporate
purposes.

                  Section 17.  NO OBLIGATION TO EXERCISE OPTION.

                  The granting of an Option shall impose no obligation upon the
Optionee to exercise such Option.

                  Section 18.  APPROVAL OF STOCKHOLDERS.

                  This Plan shall become effective on the date that it is
adopted by the Board; provided that it shall become limited to a non-qualified
stock option plan if it is not approved by the stockholders of a majority of the
Company's outstanding voting stock within one year (365 days) of its adoption by
the Board. The Board may grant Options hereunder prior to approval of the Plan,
or any material amendments thereto, by the holders of a majority of the
Company's outstanding voting stock; provided that any and all Options so granted
shall be converted into non-qualified stock options if the Plan, or a material
amendment, is not approved by such stockholders within 365 days of its adoption
or material amendment.

                  Section 19.  CONDITIONS UPON ISSUANCE OF SHARES.

                  (a) Options granted under the Plan are conditioned upon the
Company obtaining any required permit or order from appropriate governmental
agencies, authorizing the Company to issue such Options and Shares issuable upon
the exercise thereof.

                  (b) Shares shall not be issued pursuant to the exercise of an
Option 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, the Securities 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.

                  (c) As a condition to the exercise of an Option, the Board may
require the person exercising such Option to execute an agreement with, and/or
may require the person exercising such Option to make any representation and/or
warranty to, the Company as may be, in the judgment of counsel to the Company,
required under applicable law or regulation, including but not limited to, a
representation and warranty that the Shares are being purchased only for
investment and without any present intention to sell or distribute such Shares
if, in the opinion of counsel for the Company, such a representation and
warranty is appropriate under any of the aforementioned relevant provisions of
law.

                  Section 20.  RESERVATION OF SHARES.

                  (a) The Company, during the term of this Plan, shall at all
times reserve and keep available such number of Shares as shall be sufficient to
satisfy the requirements of the Plan.

                  (b) The Company, during the term of this Plan, shall use its
best efforts to seek to obtain from appropriate regulatory agencies any
requisite authorization in order to issue and sell such number of Shares as
shall be sufficient to satisfy the requirements of the Plan. The inability of
the Company to obtain from any such regulatory agency having jurisdiction the
requisite authorization(s) deemed by the Company's counsel to be necessary for
the lawful issuance and sale of any Shares hereunder, or the inability of the
Company to confirm to its satisfaction that any issuance and sale of any Shares
hereunder will meet applicable legal requirements, shall relieve the Company of
any liability in respect to the failure to issue or sell such Shares as to which
such requisite authority shall not have been obtained.

                  Section 21.  OTHER AGREEMENTS.

                  Options shall be evidenced by an Option Agreement in such form
or forms as the Board (subject to the terms and conditions of this Plan) may
from time to time approve, which Option Agreement shall evidence and reflect the
terms and conditions of an Option as set forth in Section 6 hereof. Upon
exercise of an Option, the Optionee shall execute and deliver to the Company a
Stock Purchase and Restriction Agreement in such form or forms as the Board
shall approve from time to time. The Administrator may, from time to time,
require such other agreements in connection with the Option as it, in its sole
discretion, deems advisable. The Option Agreement and the Stock Purchase and
Restriction Agreement and any other agreement required by the Plan or the Option
Agreement, as determined by the Board, may contain such other provisions as the
Board in its discretion deems advisable and that are not inconsistent with the
provisions of this Plan, including, without limitation, restrictions upon or
conditions precedent to the exercise of the Option.

                  Section 22.  TAXES, FEES, EXPENSES AND WITHHOLDING.

                  (a) The Company shall pay all original issue and transfer
taxes (but not income taxes, if any) with respect to the grant of an Option
and/or the issue and transfer of Shares pursuant to the exercise thereof, and
all other fees and expenses necessarily incurred by the Company in connection
therewith, and will, from time to time, use its best efforts to comply with all
laws and regulations that, in the opinion of counsel for the Company, shall be
applicable thereto.

                  (b) The granting of Options hereunder and the issuance of
Shares pursuant to the exercise thereof is conditioned upon the Company's
reservation of the right to withhold in accordance with any applicable law, from
any compensation or other amounts payable to the Optionee, any taxes required to
be withheld under federal, state or local law as a result of the grant or
exercise of such Option or the sale of the Shares issued upon exercise thereof.
To the extent that compensation or other amounts, if any, payable to the
Optionee is insufficient to pay any taxes required to be so withheld, the
Company may, in its sole discretion, require the Optionee (or such other person
entitled herein to exercise the Option), as a condition to the exercise of an
Option, to pay in cash to the Company an amount sufficient to cover such tax
liability or otherwise to make adequate provision for the Company's satisfaction
of its withholding obligations under federal, state and local law.

                  Section 23.  NOTICES.

                  Any notice to be given to the Company pursuant to the
provisions of this Plan shall be addressed to the Company in care of its
Secretary (or such other person as the Company may designate from time to time)
at its principal executive office, and any notice to be given to an Optionee
shall be delivered personally or addressed to the Optionee at the address given
beneath the signature of the Optionee on his or her Option Agreement, or at such
other address as such Optionee or his or her permitted transferee (upon the
transfer of the Shares) may hereafter designate in writing to the Company. Any
such notice shall be deemed duly given when

                                      -16-
<PAGE>

enclosed in a properly sealed envelope or wrapper addressed as aforesaid,
registered or certified, and deposited, postage and registry or certification
fee prepaid, in a post office or branch post office regularly maintained by the
United States Postal Service. It shall be the obligation of each Optionee and
each permitted transferee holding Shares purchased upon exercise of an Option to
provide the Secretary of the Company, by letter mailed as provided herein, with
written notice of his or her direct mailing address.

                  Section 24.  NO ENLARGEMENT OF RIGHTS.

                  This Plan is purely voluntary on the part of the Company, and
the continuance of the Plan shall not be deemed to constitute a contract between
the Company and any Employee or Consultant, or to be consideration for or a
condition of the employment or service of any Employee or Consultant as the case
may be. Nothing contained in this Plan shall be deemed to give any Employee or
Consultant the right to be retained in the employ or service of the Company or
BCI, or to interfere with the right of the Company or BCI to discharge or retire
any Employee or Consultant thereof at any time. No Employee or Consultant shall
have any right to or interest in Options authorized hereunder prior to the grant
thereof to such Employee or Consultant, and upon such grant such Employee or
Consultant shall have only such rights and interests as are expressly provided
herein, subject, however, to all applicable provisions of the Company's
Certificate of Incorporation, as the same may be amended from time to time.

                  Section 25.  INFORMATION TO OPTIONEES.

                  The Company, upon request, shall provide without charge to
each Optionee copies of such annual and periodic reports as are provided by the
Company to its stockholders generally.

                  Section 26.  AVAILABILITY OF PLAN.

                  A copy of this Plan shall be delivered to the Secretary of the
Company and shall be shown to any eligible person making reasonable inquiry
concerning it.

                  Section 27.  INVALID PROVISIONS.

                  In the event that any provision of this Plan is found to be
invalid or otherwise unenforceable under any applicable law, such invalidity or
unenforceability shall not be construed as rendering any other provisions
contained herein as invalid or unenforceable, and all such other provisions
shall be given full force and effect to the same extent as though the invalid or
unenforceable provision was not contained herein.

                  Section 28.  APPLICABLE LAW.

                  This Plan shall be governed by and construed in accordance
with the laws of the State of New Jersey.

                  Section 29.  BOARD ACTION.

                  Notwithstanding anything to the contrary set forth in this
Plan, any and all actions of the Board or Committee, as the case may be, taken
under or in connection with this Plan and any agreements, instruments,
documents, certificates or other writings entered into, executed, granted,
issued and/or delivered pursuant to the terms hereof, shall be subject to and
limited by any and all votes, consents, approvals, waivers or other actions of
all or certain stockholders of the Company or other persons required pursuant to
(a) the Company's Certificate of Incorporation (as the same may be amended
and/or restated from time to time), (b) the Company's Bylaws (as the same may be
amended and/or restated from time to time), and (c) any other agreement,
instrument, document or writing now or hereafter existing, between or among the
Company and its stockholders or other persons (as the same may be amended from
time to time).

                  Section 30.  MISCELLANEOUS.

                  This Plan is intended to comply with the conditions and
requirements for employee benefit plans under Rule 16b-3, as promulgated under
Section 16 of the Exchange Act, such that Options granted pursuant to the Plan
will be exempted from the provisions of Section 16(b) thereof. To the extent
that any provision of the Plan would cause a conflict with such requirements,
such provision shall be deemed null and void to the extent permitted by
applicable law. This section shall not be applicable if no class of the
Company's equity securities is then registered pursuant to Section 12 of the
Exchange Act.

                           (B) RIGHT TO EXERCISE.

                                    (i) Options that have not yet vested may not
be exercised.

                                    (ii) The Option may not be exercised for a
fraction of a Share.

                                    (iii) In the event of Optionee's death,
Disability or other termination of service, the exercisability shall be governed

after the date of expiration of the term of the Option, as set forth in Section

                           (C) METHOD OF EXERCISE. The Option shall be
exercisable by written notice that shall state the election to exercise the
Option, the number of Shares in respect to which the Option is being exercised
and such other representations and agreements as to the Optionee's investment
intent with respect to such Shares as may be required by the Company hereunder
or pursuant to the provisions of the Plan. Such written notice shall be signed
by the Optionee and shall be delivered in person or by certified mail to the
Secretary of the Company or such other person as may be designated by the
Company. The written notice shall be accompanied by payment of the purchase
price, an executed Stock Purchase and Restriction Agreement and any other

Administrator, the terms of the Plan and/or this Option Agreement. The Optionee

as a stockholder with respect to such Shares notwithstanding the exercise of the
Option, until the issuance (as evidenced by the appropriate entry on the books
of the Company or of a duly authorized transfer agent of the Company) of the
stock certificate evidencing the Shares that are being issued upon exercise of
the Option. The Company will issue (or cause to be issued) such stock
certificates promptly following the exercise of the Option. The certificate or
certificates for the Shares as to which the Option shall be exercised shall be
registered in the name of the Optionee and shall contain any legend as may be
required under the Plan, the Stock Purchase and Restriction Agreement, any other
agreements required by the Administrator and/or applicable law.

                           (D) METHOD OF PAYMENT. The method of payment of the
purchase price shall be determined by the Administrator and may consist entirely
of cash, check or any combination of such methods of payment, or such other
consideration or method of payment as may be authorized by the Administrator and
permitted under the Plan.

<PAGE>

                           (E) RESTRICTIONS ON EXERCISE. The Option may not be
exercised if the issuance of the Shares upon such exercise would constitute a
violation of any applicable federal or state securities laws or other laws or
regulations. As a condition to the exercise of the Option, the Company may
require the Optionee to make any representations and warranties to the Company
as may be required by any applicable law or regulation.

                  5. INVESTMENT REPRESENTATIONS. Unless the Shares have been
registered under the Securities Act, in connection with the grant of the Option,
the Optionee represents and warrants as follows:

                           (a) The Optionee is acquiring the Option, and upon
exercise of the Option, the Optionee will be acquiring the Shares for investment
for his or her own account, not as a nominee or agent, and not with a view to,
or for resale in connection with, any distribution thereof.

                           (b) The Optionee is aware of the Company's business
affairs and financial condition and has acquired sufficient information about
the Company to reach an informed and knowledgeable decision to acquire the
Shares. The Optionee has received all information as the Optionee deems
necessary and appropriate to enable him or her to evaluate the financial risk
inherent in making an investment in the Shares and has received satisfactory and
complete information concerning the business and financial condition of the
Company in response to all inquiries in respect thereof.

                  6. TERMINATION OF EMPLOYMENT WITH COMPANY. Subject to the
provisions of Section 8 hereof, upon termination of the Optionee's employment
with the Company for any reason other than death or Disability, the Optionee
shall have the right to exercise the Option at any time within the three (3)
month period after the date of such termination to the extent that the Optionee
was entitled to exercise the Option at the date of such termination; provided,
however, that if the Optionee Transfers, then to the extent the Option is not
exercised within such three (3) month period, the unexercised portion of the
Option shall automatically convert into a non-qualified stock option and shall
continue to be exercisable up to the earlier of the expiration of the Option as
set forth in Section 2 hereof or three (3) months after termination of service
with both the Company and BCI.

                  7. DEATH OR DISABILITY OF OPTIONEE. Upon the death or
Disability of the Optionee while in the employ of the Company, the Option may be
exercised at any time within twelve (12) months after the date of death or
termination due to Disability, in the case of death, by the Optionee's estate or
by a person who acquired the right to exercise the Option by bequest or
inheritance, or, in the case of Disability, by the Optionee or his legal
guardian or representative, but in any case only to the extent the Optionee was
entitled to exercise the Option at such date; provided, however, that if such
disabled Optionee shall commence any employment


                                       -3-
<PAGE>

or engagement during such twelve (12) month period with or by a competitor of
the Company (INCLUDING, but not limited to, full or part-time employment or
independent consulting work, but EXCLUDING any employment or engagement by BCI),
as determined solely in the judgment of the Board, the Option shall terminate
immediately upon the commencement thereof. In the event the Optionee Transfers
and such Option converts to a non-qualified option as provided in Section 6
hereof, in the event of death or Disability while in the service of BCI (or the
Company, in the event of a subsequent Transfer), the Option may be exercised by
the Optionee's estate, legal guardian, or representative within the twelve (12)
month period after termination of service due to death or Disability. To the
extent that the Optionee was not entitled to exercise the Option at the date of
termination, or to the extent the Option is not exercised within the time
specified herein, the Option shall terminate. Notwithstanding the foregoing, the
Option shall not be exercisable after the expiration of the term set forth in
Section 2 hereof.

                  8. FORFEITURE OF OPTION. Notwithstanding any other provision
of the Option Agreement, if the Optionee's employment is terminated and the
Board makes a determination that the Optionee (i) has engaged in any type of
disloyalty to the Company, including without limitation, fraud, embezzlement,
theft, or dishonesty in the course of his employment, (ii) has been convicted of
a felony or other crime involving a breach of trust or other fiduciary duty owed
to the Company, (iii) has disclosed trade secrets or confidential information of
the Company, (iv) has breached any agreement with the Company in respect of
confidentiality, non-disclosure, non-competition or otherwise, then, at the
election of the Board, all unexercised Options shall terminate. In the event of
such an election by the Board, in addition to immediate termination of all
unexercised Options, the Optionee shall forfeit all Shares for which the Company
has not yet delivered share certificates to the Optionee and the Company shall
refund to the Optionee the Option price paid to the Company with respect to
those Shares. Notwithstanding anything herein to the contrary, the Company may
withhold delivery of share certificates pending the resolution of any inquiry
that could lead to a determination resulting in forfeiture. In the event the
Optionee's employment with the Company terminates, but the Optionee Transfers,
the preceding forfeiture provisions shall apply in the event Optionee's service
is terminated by BCI for any of the reasons stated in the immediately preceding
subsections (1) through (iv) hereof; provided that "BCI" shall be substituted
for "the Company" where it appears in such preceding subsections.

                  9. NON-TRANSFERABILITY OF OPTION. The Option may not be sold,
pledged, assigned, hypothecated, gifted, transferred or disposed of in any
manner either voluntarily or involuntarily by operation of law, other than by
will or by the laws of descent or distribution, and may be exercised during the
lifetime of the Optionee only by such Optionee. Subject to the foregoing and the
terms of the Plan, the terms of the Option Agreement shall be binding upon the
executors, administrators, heirs, successors and assigns of the Optionee.

                                       -4-
<PAGE>

                  10. CONTINUATION OF EMPLOYMENT. Neither the Plan nor this
Option Agreement shall confer upon any Optionee any right to continue in the
employment of the Company, or BCI in the event of Transfer, or limit in any
respect the right of the Company or BCI to discharge or release the Optionee at
any time, with or without cause and with or without notice.

                  11. WITHHOLDING. The Company reserves the right to withhold,
in accordance with any applicable laws, from any consideration payable to
Optionee any taxes required to be withheld by federal, state or local law as a
result of the grant or exercise of the Option or the sale or other disposition
of the Shares issued upon exercise of the Option. If the amount of any
consideration payable to the Optionee is insufficient to pay such taxes or if no
consideration is payable to the Optionee, then upon the request of the Company,
the Optionee (or such other person entitled to exercise the Option pursuant to
Section 7 hereof) shall pay to the Company an amount sufficient for the Company
to satisfy any federal, state or local tax withholding requirements the Company
may incur, as a result of the grant or exercise of the Option or the sale or
other disposition of the Shares issued upon the exercise of the Option.

                  12. THE PLAN. The Option is subject to, and the Company and
the Optionee agree to be bound by, all of the terms and conditions of the Plan
as such Plan may be amended from time to time in accordance with the terms
thereof. Pursuant to the Plan, the Board is authorized to adopt rules and
regulations not inconsistent with the Plan as it shall deem appropriate and
proper. A copy of the Plan in its present form is available for inspection
during business hours by the Optionee or the persons entitled to exercise the
Option at the Company's principal office.

                  13. CONVERSION TO NON-QUALIFIED OPTION. Notwithstanding
anything to the contrary set forth herein, this Option is being granted subject
to the condition that in the event the Plan is not approved by the stockholders
of the Company within 365 days of the date that the Plan was adopted by the
Board, this Option shall automatically be converted into a non-qualified stock
option.

                  14. EARLY DISPOSITION OF STOCK. Subject to the fulfillment by
the Optionee of any conditions upon the disposition of Shares received under the
Option, the Optionee hereby agrees that if he or she disposes of any Shares
received under the Option within two (2) years from date of grant or one (1)
year after such Shares were transferred to him or her upon exercise of the
Option, he or she will notify the Company in writing within thirty (30) days
after the date of such disposition. The Optionee acknowledges that disposition
by him or her within two years from the date of grant and one year from the date
of exercise of the Option would disqualify him or her from capital gain
treatment for any gain realized upon such disposition.

                           (B)      RIGHT TO EXERCISE.

                                    (i) Options that have not yet vested may not
be exercised.

                                    (ii) The Option may not be exercised for a
fraction of a Share.

                                    (iii) In the event of Optionee's death,
Disability or other termination of service, the exercisability shall be governed
by this Section 4, Sections 6 and 7 hereof, and the provisions of the Plan.

                                    (iv) In no event may the Option be exercised
after the date of expiration of the term of the Option, as set forth in Section
2 hereof.

                           (C) METHOD OF EXERCISE. The Option shall be
exercisable by written notice that shall state the election to exercise the
Option, the number of Shares in respect to which the Option is being exercised
and such other representations and agreements as to the Optionee's investment
intent with respect to such Shares as may be required by the Administrator or
pursuant to the provisions of the Plan. Such written notice shall be signed by
the Optionee and shall be delivered in person or by certified mail to the
Secretary of the Company or such other person as may be designated by the
Company. The written notice shall be accompanied by payment of the purchase
price, an executed Stock Purchase and Restriction Agreement and any other
agreements required by the Administrator, the terms of the Plan and/or this
Option Agreement. The Option will be deemed to be exercised upon the receipt by
the Company of such written notice, payment of the purchase price, the Stock
Purchase and Restriction Agreement and any other agreements required by the
Administrator, the terms of the Plan and/or this Option Agreement. The Optionee
shall have no right to vote or receive dividends and shall have no other rights
as a stockholder with respect to such Shares, notwithstanding the exercise of

stock certificates promptly following the exercise of the Option. The
certificate or certificates for the Shares as to which the Option shall be
exercised shall be registered in the name of the Optionee and shall contain any
legend as may be required under the Plan, the Stock Purchase and Restriction
Agreement, any other agreements required by the Administrator and/or applicable
law.

                           (D) METHOD OF PAYMENT. The method of payment of the
purchase price shall be determined by the Administrator and may consist entirely
of cash, check or any combination of such methods of payment, or such other
consideration or method of payment as may be authorized by the Administrator and
permitted under the Plan.

                           (E) RESTRICTIONS ON EXERCISE. The Option may not be
exercised if the issuance of the Shares upon such exercise would constitute a
violation of any applicable federal or state securities laws or other laws or
regulations. As a condition to the exercise of the Option,

                                      -2-
<PAGE>

the Company may require the Optionee to make any representations and warranties
to the Company as may be required by any applicable law or regulation.

                  5. INVESTMENT REPRESENTATIONS. Unless the Shares have been
registered under the Securities Act, in connection with the acquisition of the
Option, the Optionee represents and warrants as follows:

                           (A) The Optionee is acquiring the Option, and upon
exercise of the Option, Optionee will be acquiring the Shares for investment for
his or her own account, not as a nominee or agent, and not with a view to, or
for resale in connection with, any distribution thereof.

                           (B) The Optionee is aware of the Company's business
affairs and financial condition and has acquired sufficient information about
the Company to reach an informed and knowledgeable decision to acquire the
Shares. The Optionee has received all such information as the Optionee deems
necessary and appropriate to enable him or her to evaluate the financial risk
inherent in making an investment in the Shares and has received satisfactory and
complete information concerning the business and financial condition of the
Company in response to all inquiries in respect thereof.

                  6. TERMINATION OF RELATIONSHIP WITH THE COMPANY. Subject to
the provisions of Section 8 hereof, upon termination of the Optionee's service
with the Company, including termination of service with BCI, for any reason
other than death or Disability, the Optionee shall have the right to exercise
this Option up to the Vested Amount as of the date of termination for a period
of three (3) months from the date of such termination, provided that the
Optionee may only exercise the Option to the extent that the Optionee was
entitled to exercise the Option at the date of such termination; provided,
however, that the Optionee shall not be considered to have terminated his
relationship with the Company if he Transfers.

                  7. DEATH OR DISABILITY OF OPTIONEE. Upon the death or
Disability of the Optionee while in the service of the Company, including
termination of service with BCI, the Option may be exercised up to the Vested
Amount at any time within twelve (12) months after the date of death or
termination due to Disability provided the Optionee was entitled to exercise the
Option at the date of his or her death or termination due to Disability. In the
case of death, the Option may be exercised by the Optionee's estate or by a
person who acquired the right to exercise this Option by bequest or inheritance.
In the case of Disability, the Option may be exercised by the Optionee or his or
her legal guardian or representative, but in any case, the Option may be
exercised only to the extent that the Optionee was entitled to exercise the
Option at such date; provided, however, that if such disabled Optionee shall
commence any employment or engagement during such twelve (12) month period with
or by a competitor of the Company (INCLUDING, but not limited to, full or
part-time employment or independent consulting work, but EXCLUDING any
employment or engagement by BCI), as determined solely in the judgment of the
Board, the Option shall terminate immediately upon the commencement thereof. To
the extent that the Optionee was not entitled to exercise the Option at the date
of termination, or to the extent the Option is not exercised within the time
specified herein, the Option shall terminate.

                                       -3-

<PAGE>

Notwithstanding the foregoing, the Option shall not be exercisable after the
expiration of the term set forth in Section 2 hereof.

                  8. FORFEITURE OF OPTION. Notwithstanding any other provision
of this Option Agreement, if the Optionee's service with the Company or BCI is
terminated and the Board makes a determination that the Optionee (i) has engaged
in any type of disloyalty to the Company or BCI, including without limitation,
fraud, embezzlement, theft, or dishonesty in the course of his employment or
engagement, (ii) has been convicted of a felony or other crime involving a
breach of trust or other fiduciary duty owed to the Company or BCI, (iii) has
disclosed trade secrets or confidential information of the Company or BCI, or
(iv) has breached any agreement with the Company or BCI in respect of
confidentiality, non-disclosure, non-competition or otherwise, then, at the
election of the Board, all unexercised Options shall terminate. In the event of
such an election by the Board, in addition to immediate termination of all
unexercised Options, the Optionee shall forfeit all Shares for which the Company
has not yet delivered share certificates to the Optionee and the Company shall
refund to the Optionee the Option price paid to the Company with respect to
those Shares. Notwithstanding anything herein to the contrary, the Company may
withhold delivery of share certificates pending the resolution of any inquiry
that could lead to a determination resulting in forfeiture.

                  9. NON-TRANSFERABILITY OF OPTION. The Option may not be sold,
pledged, assigned, hypothecated, gifted, transferred or disposed of in any
manner either voluntarily or involuntarily by operation of law, other than by
will or by the laws of descent or distribution, and may be exercised during the
lifetime of the Optionee only by such Optionee. Subject to the foregoing and the
terms of the Plan, the terms of this Option Agreement shall be binding upon the
executors, administrators, heirs, successors and assigns of the Optionee.

                  10. CONTINUATION OF EMPLOYMENT OR ENGAGEMENT. Neither the Plan
nor this Option Agreement shall confer upon any Optionee any right to continue
in the service of the Company or BCI or limit, in any respect, the right of the
Company or BCI to discharge or release the Optionee at any time, with or without
cause and with or without notice.

                  11. WITHHOLDING. The Company reserves the right to withhold,
in accordance with any applicable laws, from any consideration payable to the
Optionee any taxes required to be withheld by federal, state or local law as a
result of the grant or exercise of the Option or the sale or other disposition
of the Shares issued upon exercise of the Option. If the amount of any
consideration payable to the Optionee is insufficient to pay such taxes or if no
consideration is payable to the Optionee, then upon the request of the Company,
the Optionee (or such other person entitled to exercise the Option pursuant to
Section 7 hereof) shall pay to the Company an amount sufficient for the Company
to satisfy any federal, state or local tax withholding requirements the Company
may incur as a result of the grant or exercise of the Option or the sale or
other disposition of the Shares issued upon the exercise of the Option.

                  12. THE PLAN. This Option Agreement is subject to, and the
Company and the Optionee agree to be bound by, all of the terms and conditions
of the Plan as such Plan may be amended from time to time in accordance with the
terms thereof. Pursuant to the Plan, the Board

                                       -4-

is authorized to adopt rules and regulations not inconsistent with the Plan as
it shall deem appropriate and proper. A copy of the Plan in its present form is
available for inspection during business hours by the Optionee or the persons
entitled to exercise the Option at the Company's principal office.

                  13. ENTIRE AGREEMENT. This Option Agreement, together with the
Plan, and any other and the other exhibits attached thereto or hereto,
represents the entire agreement between the parties.

                  14. GOVERNING LAW. This Option Agreement shall be construed in
accordance with the laws of the State of New Jersey.

                  15. AMENDMENT. Subject to the provisions of the Plan, this
Option Agreement may only be amended by a writing signed by each of the parties
hereto.

                  THE OPTION AND THE SECURITIES THAT MAY BE PURCHASED UPON
EXERCISE OF THE OPTION HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF

his or her Shares except as otherwise expressly provided in this Agreement.

contained herein, the Optionee may transfer all or any of his or her Shares (i)
by way of gift to his or her spouse, parents, siblings, or lineal descendants of

or the Optionee, provided that any such transferee shall agree in writing with
the Company, prior to, and as a condition precedent to such transfer, to be
bound by all of the provisions of this Agreement to the same extent as if such
transferee were the Optionee, or (ii) by will or the laws of descent and
distribution, in which event each such transferee shall be bound by all of the
provisions of this Agreement to the same extent as if such transferee were the
Optionee.

                           (c) Any purported transfer in violation of the
provisions of this Agreement shall be void AB INITIO.

                  3.       TERMINATION OF EMPLOYMENT OR ENGAGEMENT.

                           (a) In the event of the termination of the employment
or engagement (or other relationship) of the Optionee for any reason, including
termination of employment or engagement with BCI, the Company (which term, for
purposes of this Section 3, shall include the designees of the Company) shall
have the right to purchase from, and if the Company exercises its option
pursuant to subparagraphs (d), (e) and (f) below, the Optionee shall sell to the
Company upon the exercise of such right at a purchase price per Share equal to
the Fair Market Value per share as at the date of termination, all of the Shares
owned by the Optionee.

                           (b) In the event the Optionee does not exercise the
Option until after the Optionee's termination of employment or other engagement
with the Company or BCI, the Company shall have the right to purchase from, and

below, the Optionee shall sell to the Company upon the exercise of such right at

                           (c) The number of Shares subject to repurchase

or any subdivision, combination or reclassification of the outstanding capital
stock of the Company or received in exchange for the Shares.

                           (d) In order to exercise the option to purchase

<PAGE>

                           (e) If the Company elects not to exercise its rights
pursuant to this Section 3 or if the Company is legally prohibited from or
unable to repurchase the Shares during the period referred to below, then the
Company shall notify the Optionee and each designee of the Company, if any,
within the 60-day period following (i) with respect to a repurchase pursuant to
Section 3(a), the termination of employment or engagement of the Optionee or
(ii) with respect to a repurchase pursuant to Section 3(b), the date of exercise
of the Option. In such event, the designees shall have the right, during the
30-day period following the Company's notice, to purchase such number of Shares
as the Company shall designate, on the same terms and conditions as were
applicable to the Company, which right shall be exercised by giving written
notice of acceptance to the Company specifying the number of Shares which such
designee elects to purchase and the purchase price therefor.

                           (f) The repurchase of Shares hereunder shall be made
on a date selected by the Company, within 120 days after (i) with respect to a
repurchase pursuant to Section 3(a), the termination of employment or engagement
or (ii) with respect to a repurchase pursuant to Section 3(b), the date of
exercise of the Option, by delivery of payment to the Optionee, by check or wire
transfer, against receipt of one or more certificates, properly endorsed,
evidencing the Optionee's Shares to be so repurchased.

                           (g) Anything contained herein to the contrary
notwithstanding, at the option of the Company, any purchaser of Shares pursuant
to Section 3 which is not the Company shall agree in writing, in advance, to be
bound by and comply with all applicable provisions of this Agreement.

                  4.       RIGHT OF FIRST REFUSAL ON DISPOSITIONS.

                           (a) If at any time the Optionee desires to sell all
or any part of his or her Shares pursuant to a bona fide offer from a third
party (the "Proposed Transferee"), then the Optionee shall submit a written
offer (the "Offer") to sell such Shares (the "Offered Shares") to the Company or
any entity or person designated by the Company ("designee"), on terms and
conditions, including price, not less favorable to the Company or its designee
than those on which the Optionee proposes to sell such Offered Shares to the
Proposed Transferee. The Offer shall disclose the identity of the Proposed
Transferee, the number of Offered Shares proposed to be sold, the total number
of Shares owned by the Optionee, the terms and conditions, including price, of
the proposed sale, and any other material facts relating to the proposed sale.
The Offer shall further state that the Company or its designee may acquire, in
accordance with the provisions of this Agreement, all or any portion of the
Offered Shares for the price and upon the other terms and conditions set forth
therein.

                           (b) If the Company (or its designee, if one exists)
desires to purchase all or any part of the Offered Shares, then the Company or
its designee shall communicate in writing its election to purchase (an
"Acceptance") to the Optionee, which Acceptance shall state the number of
Offered Shares the Company or its designee desires to purchase and shall be
given to the Optionee within thirty (30) days after the date the Offer was made
to the Company. The Acceptance shall, when taken in conjunction with the Offer,
be deemed to constitute a valid,


                                       -3-
<PAGE>

legally binding and enforceable agreement for the sale and purchase of such
Offered Shares. Sales of the Offered Shares to be sold to the Company or its
designee pursuant to this Section 4 shall be made at the offices of the Company
on the 45th day following the date the Offer was made (or if such 45th day is
not a business day, then on the next succeeding business day). Such sales shall
be effected by the Optionee's delivery to the Company a certificate or
certificates evidencing the Offered Shares to be purchased by the Company or its
designee, duly endorsed for transfer to the Company or its designee, as the case
may be, which Shares shall be delivered free and clear of all liens, charges,
claims, and encumbrances of any nature whatsoever, against payment to the
Optionee of the purchase price therefor by the Company or its designee, as the
case may be.

                           (c) If the Company or its designee does not purchase
all of the Offered Shares, then the Offered Shares not so purchased may be sold
by the Optionee at any time within 90 days after the date the Offer was made to
the Company. Any such sale shall be to the Proposed Transferee, at not less than
the price and upon other terms and conditions, if any, not more favorable to the
Proposed Transferee than those specified in the Offer. Any Offered Shares not
sold within such 90-day period shall continue to be subject to the requirements
of a prior offer pursuant to this Section 4.

                  5. FAILURE TO DELIVER SHARES. If the Optionee becomes
obligated to sell any Shares to the Company or its designee under this Agreement
and fails to deliver such Shares in accordance with the terms of this Agreement,
then the Company or its designee may, at its option, in addition to all other
remedies it may have, send to the Optionee the purchase price for such Shares as
is herein specified. Thereupon, the Company upon written notice to the Optionee,
(a) shall cancel on its books the certificate or certificates representing the
Shares to be sold and (b) in the case of a designee, shall issue, in lieu
thereof, in the name of such designee, a new certificate or certificates
representing such Shares, and thereupon all of the Optionee's rights in and to
such Shares shall terminate.

                  6. FURTHER LIMITATION AS TO TRANSFERS BY THE STOCKHOLDER. In
addition to the other restrictions provided in this Agreement or otherwise, if
requested by the Company or its underwriters for a public offering of securities
of the Company, the Optionee shall not sell or otherwise transfer or dispose of
any Shares or other securities of the Company held by such Optionee during the
period of fourteen (14) days before, and one hundred eighty (180) days
following, the effective date of a registration statement filed by the Company
with the Securities and Exchange Commission relating to such offering (other
than a registration statement on Form S-8 or Form S-4, or their successors, or
any other comparable form for similarly limited purposes promulgated after the
date hereof, or any registration statement covering only securities proposed to
be issued in exchange for securities or assets of another corporation).

                  7.       REMEDIES.

                           (a) The Optionee expressly agrees that the Company or
its designee, as the case may be, will be irreparably damaged if this Agreement
is not specifically enforced. In case any one or more of the covenants and/or
agreements set forth in this Agreement shall have


                                       -4-
<PAGE>

been breached by the Optionee, the Company or its designee (as the case may be)
may proceed to protect and enforce their rights either by suit in equity and/or
by action at law, including, but not limited to, an action for damages as a
result of any such breach; and/or an action for specific performance of any such
covenant or agreement contained in this Agreement and/or a temporary or
permanent injunction, in any case without showing any actual damage. The rights,
powers and remedies of the parties under this Agreement are cumulative and not
exclusive of any other right, power or remedy which such parties may have under
any other agreement or law. No single or partial assertion or exercise of any
right, power or remedy of a party hereunder shall preclude any other or further
assertion or exercise thereof.

                           (b) The Optionee agrees that, until a public market
for the Shares exists, the Shares cannot be readily purchased, sold, or
evaluated in the open market, that they have a unique and special value, and
that the Company and its stockholders would be irreparably damaged if the terms
of this Agreement were not capable of being specifically enforced, and for this
reason, among others, the Company shall be entitled to a decree of specific
performance of the terms hereof or an injunction restraining violation of this
Agreement, said right to be in addition to any other remedies of the Company.

                  8. ASSIGNMENT. The Company may assign its rights under this
Agreement to one or more persons or entities, who shall have the right to so
exercise such rights in his, her or its own name and for his, her or its own
account. If the exercise of any such right requires the consent of any state or
other regulatory authority, then the Optionee shall cooperate with the Company
in requesting such consent.

                  9. ADJUSTMENT. The number of Shares subject to the terms and
provisions of this Agreement during the term of this Agreement shall be adjusted
to give effect to any stock dividend or liquidating dividend of cash and/or
property, stock split or other change or reclassification of the outstanding
securities of the Company. In such event, any and all new, substituted or
additional securities or other property to which the Optionee is entitled by
reason of his or her ownership of Shares shall be immediately subject to the
terms of this Agreement, and be included in the term "Shares" for all purposes
with the same force and effect as the Shares presently subject to such rights
and restrictions.

                  10. LEGENDS. All certificates representing any Shares of the
Company subject to the provisions of this Agreement shall have endorsed thereon
the following legend in substantially the following form unless in the opinion
of counsel such legend is no longer necessary:

                  THE SHARES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN
                  REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED OR ANY
                  APPLICABLE STATE SECURITIES LAWS. THESE SHARES HAVE NOT BEEN
                  ACQUIRED WITH A VIEW TO DISTRIBUTION OR RESALE, AND MAY NOT BE
                  SOLD, ASSIGNED, EXCHANGED, MORTGAGED, PLEDGED, HYPOTHECATED OR

                                       -5-
<PAGE>

                  OTHERWISE TRANSFERRED OR DISPOSED OF, BY GIFT OR OTHERWISE, OR
                  IN ANY WAY ENCUMBERED WITHOUT AN EFFECTIVE REGISTRATION
                  STATEMENT FOR SUCH SHARES UNDER THE SECURITIES ACT OF 1933, AS
                  AMENDED, AND ANY APPLICABLE STATE SECURITIES LAWS, OR AN
                  OPINION OF COUNSEL SATISFACTORY TO BLUESTONE SOFTWARE, INC.
                  THAT REGISTRATION IS NOT REQUIRED UNDER SUCH ACT AND UNDER
                  APPLICABLE STATE SECURITIES LAWS. MOREOVER, THE SHARES
                  REPRESENTED BY THIS CERTIFICATE ARE SUBJECT TO AND RESTRICTED
                  BY THE PROVISIONS OF A CERTAIN STOCK PURCHASE AND RESTRICTION
                  AGREEMENT BETWEEN BLUESTONE SOFTWARE, INC. AND THE
                  STOCKHOLDER, A COPY OF WHICH AGREEMENT WILL BE FURNISHED BY
                  BLUESTONE SOFTWARE, INC. UPON WRITTEN REQUEST AND WITHOUT
                  CHARGE, AND ALL OF THE PROVISIONS OF SUCH AGREEMENT ARE
                  INCORPORATED BY REFERENCE IN THIS CERTIFICATE.

                  11. INVESTMENT REPRESENTATIONS. Unless the Shares have been
registered under the Securities Act of 1933, as amended (the "Act"), in which
event the Company will so advise Optionee in writing, Optionee acknowledges,
agrees, represents and warrants, in connection with the proposed purchase of the
Shares, as follows:

                           (a) The Optionee is purchasing the Shares solely for
his or her own account for investment and not with a view to, or for resale in
connection with any distribution thereof within the meaning of the Act. The
Optionee further represents that he or she does not have any present intention
of selling, offering to sell or otherwise disposing of or distributing the
Shares or any portion thereof; and that the entire legal and beneficial interest
of the Shares he or she is purchasing is being purchased for, and will be held
for the account of, the Optionee only and neither in whole nor in part for any
other person.

                           (b) The Optionee is aware of the Company's business
affairs and financial condition and has acquired sufficient information about
the Company to reach an informed and knowledgeable decision to acquire the
Shares. The Optionee has a preexisting personal or business relationship with
the officers and directors of the Company and that the Optionee has such
knowledge and experience in business and financial matters to enable him or her
to evaluate the risks of the prospective investment and to make an informed
investment decision with respect thereto and that the Optionee has the capacity
to protect his or her own interests in connection with the purchase of the
Shares. The Optionee has discussed the Company and its plans, operations and
financial condition with its officers, has received all such information as the
Optionee deems necessary and appropriate to enable him or her to evaluate the
financial risk inherent in making an investment in the Shares and has received
satisfactory and

                                       -6-
<PAGE>

complete information concerning the business and financial condition of the
Company in response to all inquiries in respect thereof.

                           (c) The Optionee realizes that his or her purchase of
the Shares will be a speculative investment and that Optionee is able, without
impairing his or her financial condition, to hold the Shares for an indefinite
period of time and to suffer a complete loss on the investment.

                           (d) The Company has disclosed in writing that: (i)
the sale of the Shares has not been registered under the Act, and the Shares
must be held indefinitely unless a transfer of them is subsequently registered
under the Act or an exemption from such registration is available, and the
Company is under no obligation to register the Shares; and (ii) the Company
shall make a notation in its records of the aforementioned restrictions on
transfer and legends.

                           (e) The Optionee is aware of the provisions of Rule
144, promulgated under the Act, which, in substance, permits limited public
resale of "restricted securities" acquired, directly or indirectly, from the
issuer thereof (or an affiliate of such issuer) in a non-public offering subject
to the satisfaction of certain conditions, including among other things: the
resale occurring not less than one (1) year from the date Optionee has purchased
and paid for the Shares; the availability of certain public information
concerning the Company; the sale being through a broker in an unsolicited
"brokers' transaction" or in a transaction directly with a market maker (as said
term is defined under the Securities Exchange Act of 1934, as amended); and that
any sale of the Shares may be made by Optionee, if Optionee is an affiliate of
the Company, only in limited amounts during any three-month period not exceeding
specified limitations. The Optionee understands that at the time Optionee wishes
to sell the Shares there may be no public market upon which to make such a sale,
and that, even if such public market then exists, the Company may not be
satisfying the current public information requirements of Rule 144, and that, in
such event, Optionee would be precluded from selling the Shares under Rule 144
even if the one-year minimum holding period had been satisfied. The Optionee
understands that in the event all of the requirements of Rule 144 are not
satisfied, registration under the Act, compliance with Regulation A, or some
other registration exemption will be required; and that, notwithstanding the
fact that Rule 144 is not exclusive, the Staff of the SEC has expressed its
opinion that persons proposing to sell private placement securities other than
in a registered offering and otherwise than pursuant to Rule 144 will have a
substantial burden of proof in establishing that an exemption from registration
is available for such offers or sales, and such persons and their respective
brokers who participate in such transactions do so at their own risk.

                           (f) Without in any way limiting the Optionee's
representations and warranties set forth herein, the Optionee shall in no event
make any disposition of all or any portion of the Shares that he or she is
purchasing unless and until:

                                    (i) there is then in effect a Registration
Statement under the Act covering such proposed disposition and such disposition
is made in accordance with said Registration Statement; or


                                       -7-
<PAGE>

                                    (ii) the Optionee shall have (a) notified
the Company of the proposed disposition and furnished the Company with a
detailed statement of the circumstances surrounding the proposed disposition,
and (b) furnished the Company with an opinion of Optionee's own counsel
(satisfactory to the Company) to the effect that such disposition will not
require registration of such shares under the Act, and such opinion of the
Optionee's counsel shall have been concurred in by counsel for the Company and
the Company shall have advised the Optionee of such concurrence.

                  12. ESCROW. As security for the Optionee's faithful
performance of the terms of this Agreement and to insure the availability for
delivery of the Optionee's Shares upon exercise, under this Agreement, of the
rights of the Company and the rights of the other beneficiaries to this
Agreement, the Optionee shall, if requested in writing by the Company, deliver
to and deposit with the Chief Financial Officer of the Company or his nominee
(the "Escrow Agent"), as Escrow Agent in this transaction, two Stock Assignments
duly endorsed (with date and number of shares blank) in the form attached hereto
as ATTACHMENT A, together with the certificate or certificates evidencing the
Shares; such documents are to be held by the Escrow Agent and delivered to said
Escrow Agent pursuant to the Joint Escrow Instructions of the Company and
Optionee set forth in ATTACHMENT B attached hereto and incorporated herein by
this reference, which instructions shall also be delivered to the Escrow Agent
at the closing hereunder.

                  13. RESTRICTION ON ALIENATION. The Optionee shall not sell,
transfer, gift, pledge, hypothecate, assign or otherwise dispose of any of the
Shares or any right or interest therein, whether voluntary, by operation of law
or otherwise, without the prior written consent of the Company, except a
transfer which meets the requirements of this Agreement. Any sale, transfer,
gift, pledge, hypothecation, assignment or disposition or purported sale,
transfer or other disposition of such Shares by Optionee shall be null and void
AB INITIO unless the terms, conditions and provisions of this Agreement are
strictly observed.

                  14. TERM. Except for Sections 3, 4 and 5 hereof, which shall
terminate upon the consummation of a Public Offering of shares of the Company's
equity capital, this Agreement shall continue in full force and effect until
such time as the Optionee has transferred all of the Shares (other than pursuant
to Section 2(b)) in accordance with the terms of this Agreement.

                  15.      MISCELLANEOUS.

                                    (a) The Company shall not be required (i) to
transfer on its books any Shares that shall have been sold or transferred in
violation of any of the provisions set forth in this Agreement, or (ii) to treat
as owner of such Shares or to accord the right to vote as such owner or to pay
dividends to any transferee to whom such Shares shall have been so transferred.

Optionee shall, during the term of this Agreement, exercise all rights and
privileges of a stockholder of the Company with respect to the Shares.

                           (c) The parties agree to execute such further
instruments and to take such further action as may reasonably be necessary to
carry out the intent of this Agreement.

                           (d) Any notice, consent or other communication
required or permitted hereunder shall be given in writing and shall be deemed
effectively given: (a) upon personal delivery; (b) two (2) business days after
day of deposit if sent by regular mail; (c) one (1) business day after the
business day of deposit with a carrier if sent by Federal Express, Express Mail

other address or numbers as such party may designate by ten (10) days' advance

an Option may be conditioned on receipt by the Company of such appropriate
representations and warranties of the Optionee, including a representation and

investment, and not with a view to the public resale or distribution thereof,

regulations applicable thereto. Unless the Shares subject to the Option are
registered under the Securities Act, the Optionee shall acknowledge that the
Shares purchased on exercise of the Option are not registered under the
Securities Act and may not be sold or otherwise transferred unless the Shares
have been registered under the Securities Act in connection with the sale or
other transfer thereof, or that counsel satisfactory to the Company has issued

Shares is exempt from registration under the Securities Act, and unless said
sale or transfer is in compliance with all other applicable laws, rules and
regulations, including all applicable federal and state securities laws, rules
and regulations. Unless the Shares issued or issuable upon the exercise of an
Option are registered under the Securities Act, the certificates representing
the Shares shall contain the following legend in substantially the following

          DISTRIBUTION OR RESALE, AND MAY NOT BE SOLD, ASSIGNED, EXCHANGED,
          MORTGAGED, PLEDGED, HYPOTHECATED OR OTHERWISE TRANSFERRED OR DISPOSED
          OF, BY GIFT

               (a) In the event of a Change of Control, the Board shall have the
right, in its sole discretion, to establish an earlier date for the expiration
of the exercise of an Option (notwithstanding a later expiration of
exercisability set forth in an Option Agreement).

               (b) In addition, in the event of a Change of Control, the Board
shall have the right, in its sole discretion, subject to and conditioned upon a
Sale of the Company:

                    (i) to arrange for the successor company (or other entity)
to assume all of the rights and obligations of the Company under this Plan; or

                    (ii) to terminate this Plan and:

                         (a) to pay to all Optionees cash with respect to those
Options that are vested as of the date of the Sale of the Company in an amount
equal to the difference between the Option Price and the Fair Market Value of a
Share of Common Stock (determined as of the date the Plan is terminated)
multiplied by the number of Options that are vested as of the date of the Sale
of the Company which are held by the Optionee as of the date of the Sale of the
Company; or

                         (b) to arrange for the exchange of all Options for
options to purchase common stock in the successor corporation; or

                         (c) to distribute to each Optionee other property in an
amount equal to and in the same form as the Optionee would have received from
the successor

                                       -9-

<PAGE>

corporation if the Optionee had owned the Shares subject to Options that are
vested as of the date of the Sale of the Company rather than the Option at the
time of the Sale of the Company.

The form of payment or distribution to the Optionee pursuant to this Section
shall be determined by the Board in its sole discretion.

          Section 16. AMENDMENT OF THE PLAN.

          The Board, in its discretion, may from time to time suspend, terminate
or discontinue the Plan or revise or amend it any respect.

          Section 17. APPLICATION OF FUNDS.

          The proceeds received by the Company from the sale of Shares pursuant
to the exercise of Options shall be used for general corporate purposes.

          Section 18. CONDITIONS UPON ISSUANCE OF SHARES.

          Shares shall not be issued pursuant to the exercise of an Option
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, the Securities 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.

          Section 19. RESERVATION OF SHARES.

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

          Section 20. TAXES, FEES, EXPENSES AND WITHHOLDING OF TAXES.

               (a) TRANSFER TAXES. The Company shall pay all original issue and
transfer taxes (but not income taxes, if any) with respect to the grant of
Options and/or the issue and transfer of Shares pursuant to the exercise
thereof, and all other fees and expenses necessarily incurred by the Company in
connection therewith, and will from time to time use its best efforts to comply
with all laws and regulations which, in the opinion of counsel for the Company,
shall be applicable thereto.

               (b) WITHHOLDING RIGHT. The grant of Options hereunder and the
issuance of Shares pursuant to the exercise thereof is conditioned upon the
Company's reservation of the right to withhold in accordance with any applicable
law, from any compensation or other amounts payable to the Optionee, any taxes
required to be withheld under

                                      -10-

<PAGE>

federal, state or local law as a result of the grant or exercise of such Option
or the sale of the Shares issued upon exercise thereof. The Company may, in its
sole discretion, require the Optionee (or such other person entitled herein to
exercise the Option), as a condition of the exercise of an Option, to pay in
cash to the Company an amount sufficient to cover such tax liability or
otherwise to make adequate provision for the Company's satisfaction of its
withholding obligations under federal, state and local law.

          Section 21. NOTICES.

          Any notice to be given to the Company pursuant to the provisions of
the Plan shall be addressed to the Company in care of its Secretary (or such
other person as the Company may designate from time to time) at its principal
executive office, and any notice to be given to an Optionee shall be delivered
personally or addressed to him at the address given beneath his signature on his
Option Agreement, or at such other address as such Optionee or his permitted
transferee (upon the transfer of the Shares) may hereafter designate in writing
to the Company. Any such notice shall be deemed duly given when enclosed in a
properly sealed envelope or wrapper addressed as aforesaid, registered or
certified, and deposited, postage and registry or certification fee prepaid, in
a post office or branch post office regularly maintained by the United States
Postal Service. It shall be the obligation of each Optionee and each permitted
transferee holding Shares purchased upon exercise of an Option to provide the
Secretary of the Company, by letter mailed as provided herein, with written
notice of his direct mailing address.

          Section 22. NO ENLARGEMENT OF RIGHTS.

          The Plan is purely voluntary on the part of the Company, and the
continuance of the Plan shall not be deemed to constitute a contract between the
Company and any Non-Employee Director for the continuation of his service as a
Non-Employee Director. Nothing contained in the Plan shall be deemed to give any
Non-Employee Director the right to be retained in the service of the Company.
Upon the grant of an Option to a Non-Employee Director, he shall have only such
rights and interests as are expressly provided herein, subject, however, to all
applicable provisions of the Company's Certificate of Incorporation, as the same
may be amended from time to time.

          Section 23. INVALID PROVISIONS.

          In the event that any provision of the Plan is found to be invalid or
otherwise unenforceable under any applicable law, such invalidity or
unenforceability shall not be construed as rendering any other provisions
contained herein as invalid or unenforceable, and all such other provisions
shall be given full force and effect to the same extent as though the invalid or
unenforceable provision was not contained herein.

                                      -11-

<PAGE>

          Section 24. TERMINATION.

          The Board may terminate the Plan at any time. Unless it has been
previously terminated, the Plan shall terminate after five (5) years from the
date the Plan become effective.

          Section 25. APPLICABLE LAW.

          The Plan shall be governed by and construed in accordance with the
laws of the State of New Jersey.

                  1. RESELLER OBLIGATIONS Reseller shall use its best efforts to
sell Products in the Territory. Reseller shall not, whether directly or
indirectly, solicit sales outside the Territory. Reseller shall ensure that the
Product delivered to the end-user is accompanied by the current End-User License
Agreement.

Reseller shall at all relevant times, have in its employ a full-time technical
support representative capable of demonstrating the Products and supporting the
Products on such computer system or workstation for which Reseller distributes
Products. Reseller shall distribute software updates (available via Bluestone's
ftp site or reseller can order new documentation and media) to customers with
current support agreements.

NFR licenses are to be used for in-house evaluation and demonstration purposes
only. Any misuse of this license will result in revocation. Sapphire/Web NFR
product licenses are not intended for resale, for employee personal use at home,
or for installation at a customer site (customer product evaluations are
available through Bluestone Software Inc.'s 30 day Evaluation Program).

Reseller shall not itself create or market any product with the same or similar
functionality as the Products, during the term or this Agreement and for six
months thereafter.

Reseller shall ensure that the Product and the marketing thereof, and the
performance by Reseller of all obligations hereunder are in compliance with all
applicable legislation.

Failure to achieve quota will result in the following: Diamond Level - Resellers
will be assigned to Opal Level; Opal Level - Resellers will be subject to
Termination as per Section 6.

                  2. PRICE AND PAYMENT Reseller may purchase products from
Bluestone at Bluestone's then current list price less Discount. Price is
determined by quantity of customer order and not by aggregate orders.

To provide for quick shipment to end-users, Reseller may purchase from Bluestone
inventory copies of the Media and Manual Kits and marketing material at
Bluestone's then current reseller list price.

All Software, Media and Manual Kits and marketing materials will be delivered to
Reseller, F.O.B. Mt. Laurel, NJ, (in accordance with the International Chamber
of Commerce INCOTERMS) and Reseller will be responsible for all customs, duties,
and shipping charges. Prices are net of taxes, and Reseller shall be responsible
for payment of all applicable local sales, use, withholding, value added, and
goods and services taxes. In such jurisdictions where Bluestone is not
registered to collect use, sales, or similar taxes, Reseller shall ensure their
payment, and provide upon request to Bluestone evidence of same.

Reseller agrees to pay Bluestone within 30 days of invoice date. Bluestone
reserves the right to change the terms of payment if: (1) Reseller fails to make
a payment to Bluestone when due; or (2) in Bluestone's reasonable judgement
there has been material adverse change in Reseller's


<PAGE>



credit position. If Reseller chooses to pay using an international bank
transfer, Reseller must notify Bluestone by fax, on the day of the transfer
indicating the transfer amount, and how it should be applied to outstanding
invoices. Any bank charges for bank transfers shall be to Reseller's account.

                  3. EVALUATION, ORDERING AND RECORDS Reseller may provide to
end-users the Product in its time limited form for evaluation purposes. Reseller
may retrieve evaluation passwords from Bluestone Reseller website or similar
means.

Reseller will fax or send a Purchase Order to Bluestone specifying customer name
and address, and Product order code. Bluestone will, upon acceptance of the
order, immediately provide reseller with a permanent password. Bluestone will
normally ship the appropriate Media and Manual Kit. Reseller may ship from their
inventory and indicate this intention on their purchase order, and receive a
credit therefore from the purchase price. Reseller must ensure that every
customer receives an original and current Media and Manual Kit.

                  4. PROPRIETARY RIGHTS All title to, copyright in, and
ownership interest in the Products and all Bluestone trademarks shall at all
times remain with Bluestone. Reseller shall ensure that all Bluestone copyright
and trademark notices are prominently displayed on all related materials.

Reseller acknowledges that the Products are proprietary to Bluestone and
Reseller shall not take any action, such as reverse assembly or reverse
engineering, to derive a source code equivalent for any product software, or
copy or reproduce the functionality thereof, nor shall Reseller attempt in any
way to make the Product software operational by the end-user without obtaining
from Bluestone a permanent Password specifically for that end-user. Reseller
shall have no right to any software source code, nor rights to translation of
derivative works.

Reseller may not use, sell or otherwise permit the use of the Products except
pursuant to and as limited by the terms of this Agreement. Without limitation,
Reseller shall not copy, in whole or in part, the Product software, the Media
and Manual Kit or the marketing materials.

Reseller shall, during the term of this Agreement, use Bluestone trademarks
(registered or unregistered) solely in connection with the promotion of the
Products and Bluestone hereby grants to Reseller, during the term of this
Agreement, a nonexclusive nontransferable right to use such marks solely for the
purposes of promoting the Products as authorized herein. Reseller shall
accompany each use of a Bluestone trademark with a conspicuous notation that the
Marks are owned by Bluestone and any other proprietary legend that Bluestone
determines reasonably necessary to protect its rights therein.

Bluestone will defend, at its expense, any action brought against Reseller to
the extent that it is based on a claim that the sale or use of Products, within
the scope of this Agreement, infringes any patent, trade secret or copyright.
Bluestone will indemnify Reseller from any costs, damages and fees finally
awarded against Reseller which are attributable to such claim, provided that
Reseller notifies Bluestone promptly in writing of the claim and provides
Bluestone with


<PAGE>


information, reasonable assistance and sole authority to deliver or settle the
claim. Reseller shall have no authority to settle any claim on behalf of
Bluestone.

Should the Products become or, in Bluestone's opinion, are likely to become the
subject of a claim or infringement of patent, trade secret or copyright,
Bluestone may (1) procure for Reseller and Reseller's end-users, at no cost to
Reseller or Reseller's end-users, the right to continue to use the Product, or
(2) replace or modify the Product, to make such non-infringing, provided that
substantially the same function is performed by the replacement or modified
software, or if (1) or (2) are not commercially reasonable, terminate the
license to use such Product software, and, upon proof of removal, grant Reseller
a credit as depreciated on a stright-line five (5) year basis from date of
purchase.

Bluestone shall have no liability for any claim of copyright, trade secret or
patent infringement based on (1) the use of other than the latest Product
release from Bluestone, if such infringement could have been avoided by the such
use; or (2) the use or combination of Product with software, hardware, or other
materials not provided by Bluestone.

                  5. WARRANTIES & LIMITATION OF LIABILITY Except as provided in
this sub-section and in the limited warranty to end-users as set forth in the
End-User License Agreement, Bluestone makes no warranty or representation to
Reseller or any third parties concerning the Product, or operation thereof.

Bluestone disclaims any and all implied warranties including that of
merchantability and fitness for a particular purpose.

Bluestone liability for any damages in any action relating to the use of Product
or arising out of this agreement shall not exceed the purchase price paid by
Reseller to Bluestone for the Product at issue. In no event shall Bluestone be
liable for indirect, special, incidental or consequential damages arising out of
the use of Product or under this agreement regardless of the form of action,
even if advised of the possibility of such damages.

                  6. TERMINATION This Agreement may be terminated at any time
without recourse or compensation for such termination: (a) by Bluestone, if
Reseller has not purchased from Bluestone, in the most recently completed
Agreement quarter, Product in value equal the quarterly Quota; and (b) by either
party if the other party becomes insolvent or is declared bankrupt, or on 30
days notice providing an opportunity to cure, of the other party has materially
breached its obligations, hereunder; (c) by either party for any reason by
giving the other party at least sixty (60) days written notice.

                  7. MISCELLANEOUS Reseller agrees to maintain electronic mail
(email) access to the internet, for routine communication with Bluestone.

Reseller is an independent contractor, and is not the agent or representative of

                               SUBLEASE AGREEMENT

          THIS SUBLEASE AGREEMENT ("Sublease"), effective as of April 30, 1997,
is made by and between BLUESTONE SOFTWARE, INC., a Delaware corporation
("Sublandlord"), and BLUESTONE CONSULTING, INC., a Delaware corporation
("Subtenant").

                                   BACKGROUND

          A. Briggs Properties Partnership ("Prime Landlord"), as lessor, and
Sublandlord, as lessee, entered into a Lease dated September 27, 1993, as
amended by a First Addendum to Lease dated December 1, 1993, a Second Addendum
to Lease dated December 15, 1994, a Third Addendum to Lease dated June 1, 1995,
and a Fourth Addendum to Lease dated May 16, 1996 (collectively, "Prime Lease").
Pursuant to the Prime Lease, Prime Landlord leased to Sublandlord approximately
34,746 square feet of space ("Demised Premises") in the building located at 1000
Briggs Road, Mt. Laurel, New Jersey 08054 ("Building"), for a term expiring at
midnight on the 30 day of November, 2003.

          B. Subtenant desires to sublease from Sublandlord, and Sublandlord
desires to sublease to Subtenant, a portion of the Demised Premises in
accordance with the terms and conditions of this Sublease.

          NOW, THEREFORE, in consideration of the rents herein provided and of
the covenants and agreements herein contained, and intending to be legally bound
hereby, Sublandlord and Subtenant hereby covenant and agree as follows:

          1. SUBLEASED PREMISES. Sublandlord hereby subleases to Subtenant and
Subtenant hereby rents from Sublandlord a portion of the Demised Premises
("Subleased Premises") containing approximately ___________ square feet, as
described more particularly on EXHIBIT A attached hereto and made a part hereof.

          2. TERM OF SUBLEASE.

               (a) The term of this Sublease ("Term") shall commence on April
30, 1997 ("Commencement Date"), and shall expire on the earlier of (i) the date
on which the Prime Lease shall terminate for any reason or (ii) at 11:59 P.M. on
the scheduled termination date of the Lease ("Expiration Date").

               (b) Under no circumstances shall the Term of this Sublease extend
beyond the expiration, surrender or termination of the Prime Lease, whether the
Prime Lease expires by its own terms, is terminated for Sublandlord's default,
is surrendered by agreement of Prime Landlord and Sublandlord, or is terminated
for any other reason.

<PAGE>

               (c) Sublandlord shall attempt to obtain Prime Landlord's consent
to this Sublease. Sublandlord shall incur no liability if Sublandlord does not
obtain Prime Landlord's consent to this Sublease.

          3. USE. The Subleased Premises shall be occupied only by Subtenant and
used solely for the purpose of general office use and the sale of computer
software, training and counseling, and related activities.

          4. RENT.

               (a) Subtenant shall pay to Sublandlord, at a place designated by
Sublandlord, base rent in the annual amount of One Hundred Thousans Seven
Hundred Three Dollars ($107,703), to be paid in equal monthly installments, in
advance, on the first day of every calendar month during the Term hereof,
without deduction, abatement or set off (except as otherwise provided in this
Sublease). If the Term of this Sublease shall commence or end on a day other
than the first day of the month, the monthly rent installment due for such month
shall pro rated based on the number of rental days of such calendar month. If
any payment of base rent is received by Sublandlord more than five (5) days
after payment is due, Subtenant shall pay to Sublandlord a late payment charge
equal to five percent (5%) of such late payment.

               (b) Subtenant also shall pay Subtenant's Proportionate Share
(defined below) of "Taxes" (as such term is defined in Article IV of the Prime
Lease) for the Subleased Premises as "Taxes" are determined by the Prime
Landlord in accordance with the Prime Lease and charged to Sublandlord. The
amount payable by Subtenant to Sublandlord for Taxes shall be deemed "additional
rent" and paid within fifteen (15) days after each such tax billing is received
by Subtenant from Sublandlord.

               (c) Subtenant also shall pay Subtenant's Proportionate Share of
the "common area maintenance costs" (as such term is defined in Article XI of
the Prime Lease) for the Subleased Premises as such "common area maintenance
costs" are determined by Prime Landlord in accordance with the Prime Lease and
charged to Sublandlord. The amount payable by Subtenant to Sublandlord shall be
deemed "additional rent" and shall be paid within fifteen (15) days after each
such billing is received by Subtenant from Sublandlord.

               (d) Subtenant shall pay Subtenant's Proportionate Share of
utility costs and other services rendered or furnished to the Subleased Premises
during the Term of this Sublease such as trash disposal and janitorial services,
provided Subtenant's use is no more intensive than that of Sublandlord. Where
Subtenant shall require utilities or services beyond that provided by the Prime
Lease (including other than during normal business hours established by the
Prime Lease), Subtenant shall pay any additional charge incurred by Sublandlord
therefor. If, however, any utilities are separately metered and billed to the
Subleased Premises, Subtenant shall pay all of such charges directly to the
utility provider. The amount payable by Subtenant to

<PAGE>

Sublandlord shall be additional rent and shall be paid within fifteen (15) days
after each such billing is received by Subtenant from Sublandlord.

               (e) "Subtenant's Proportionate Share" shall be 28% which has been
determined by dividing the Subleased Premises by the Demised Premises (9,500 /
34,746 = .28) and multiplying such figure by 100%.

          5. CONDITION OF THE SUBLEASED PREMISES. Subtenant acknowledges and
represents to Sublandlord that (a) Subtenant has thoroughly inspected and
examined the Subleased Premises, (b) Subtenant is fully familiar with the
physical conditions and state of repair of the Subleased Premises, (c) Subtenant
hereby accepts the Subleased Premises in their "as is" condition as of the date
hereof and that Sublandlord shall have no obligation to perform any work in
connection with this Sublease, and (d) neither Sublandlord nor any agent of
Sublandlord has made any representation or warranty with respect to the
Subleased Premises or the Building including without limitation, any
representation or warranty with respect to the suitability or fitness of the
Subleased Premises or the Building for the conduct of Subtenant's business.

          6. PRIME LEASE.

               a. COPY OF PRIME LEASE. Sublandlord represents that the copy of
the Prime Lease attached hereto as EXHIBIT B is a true, complete and correct
copy of the Prime Lease.

               b. SUBORDINATION. This Sublease and all the rights of Subtenant
hereunder are expressly subject and subordinate to the Prime Lease and all
leases and mortgages to which the Prime Lease is subordinate. In the event of
the foreclosure of any underlying mortgage against which Sublandlord has
nondisturbance protection, Subtenant shall enjoy the same nondisturbance
protection as Sublandlord.

               c. INCORPORATION BY REFERENCE. Except as otherwise provided in
this Section 6 or elsewhere in this Sublease, all of the terms, covenants,
conditions and definitions of the Prime Lease (except such as by their nature or
purport do not relate to the Subleased Premises or are inapplicable or
inappropriate to the subleasing of the Subleased Premises pursuant to this
Sublease or are inconsistent with any of the provisions of this Sublease) are
hereby incorporated in and made part of this Sublease with the same force and
effect as though set forth at length herein. The foregoing incorporation by
reference is subject to the provisions of this Section 6, including the
following:

                    (i) References in the Prime Lease to "Lessor" (other than in
provisions of the Prime Lease which impose or relate to obligations of Prime
Landlord to repair or restore, or to perform or furnish utilities, work or
services with respect to, the Demised Premises or the Building) shall be deemed
to refer to Sublandlord under this Sublease unless the context requires that
such reference be deemed to refer to both Prime Landlord and Sublandlord;


<PAGE>

                    (ii) References in the Prime Lease to "Lessee" (other than
in provisions of the Prime Lease which grant to the lessee thereunder an
expansion option, right of first refusal or option to renew) shall be deemed to
refer to Subtenant under this Sublease;

                    (iii) Reference in the Prime Lease to "the Lease" or "this
Lease" shall be deemed to refer to this Sublease;

                    (iv) Reference in the Prime Lease to specific terms or
provisions of the Prime Lease shall be deemed to be to the provisions of the
Prime Lease incorporated herein;

                    (v) References in the Prime Lease to the "term" of the Prime
Lease shall be deemed to refer to the Term of this Sublease;

                    (vi) References in the Prime Lease to "minimum rent" or
"additional rent" or "rental" or "rent" shall be deemed to refer to the rent
payable under this Sublease, but the provisions of the Prime Lease
notwithstanding, the only rent to be paid by Subtenant is as provided in Section
4 of this Sublease;

                    (vii) Whenever a provision of the Prime Lease incorporated
herein by reference obliges Sublandlord to perform some act for the benefit of
Prime Landlord, including by way of example providing insurance or indemnity or
making repairs or permitting access, such provisions as incorporated herein
shall oblige Subtenant to perform such act to the extent applicable to the
Subleased Premises for the benefit of Prime Landlord and Sublandlord. Whenever a
provision of the Prime Lease incorporated herein by reference affords the Prime
Landlord some right against Sublandlord, such provision as incorporated herein
shall afford Prime Landlord and Sublandlord such right against Subtenant;

                    (viii) Whenever a provision of the Prime Lease incorporated
herein by reference requires or refers to Prime Landlord's consent and approval,
such provision as incorporated herein shall be deemed to require or refer to
both Prime Landlord's and Sublandlord's consent and approval. In such a case,
Subtenant shall submit its request for consent or approval to Sublandlord and
Sublandlord shall immediately submit such request for consent or approval to
Prime Landlord. Sublandlord shall notify Subtenant of Sublandlord's
determination to grant or deny its consent or approval within the time period,

any default notices under the Prime Lease given by Sublandlord or received by
Sublandlord. Immediately upon receipt thereof, Sublandlord also shall provide
Subtenant with copies of any other notices under the Prime Lease relating to the
Subleased Premises received by Sublandlord.

               (d) PROTECTION OF PRIME LEASE. Subtenant shall not do or cause to
be done or suffer or permit any act or thing which would constitute a default
under the Prime Lease or cause the Prime Lease or the rights of Sublandlord as
lessee thereunder to be terminated or which would cause Sublandlord to become
liable for any damages, costs, claims or penalties or would increase the minimum
rent or additional rent or other charges or obligations of Sublandlord as lessee
under the Prime Lease, or would adversely affect or reduce any of Sublandlord's
rights or benefits under the Prime Lease. Sublandlord agrees that it shall not
do or cause to be done, or suffer or permit to be done, any act or thing which
would constitute a default under the Prime Lease or cause the Prime Lease to be
terminated.

               (e) INDEMNIFICATION.

                    (i) Subtenant shall indemnify, defend and hold harmless
Sublandlord from and against any and all claims, actions, liabilities, losses,
damages, costs, and expenses, including, without limitation, reasonable fees for
legal counsel (collectively, "Claims") arising (A) from the use or occupancy by
Subtenant of the Subleased Premises or the Building or any business conducted
therein by Subtenant, or (B) from any condition created by or any negligence or
willful misconduct of Subtenant or its employees, agents, contractors, visitors
or licensees, in or about the Subleased Premises or any other part of the
Building, or (C) from Subtenant's failure to perform any of the obligations
imposed on it hereunder (through incorporation of the Prime Lease or otherwise),
or (D) from a termination of the Prime Lease resulting from a default by
Subtenant under this Sublease.

                    (ii) Sublandlord shall indemnify, defend and hold harmless
Subtenant from and against any and all Claims arising (A) from the negligence or
willful misconduct of Sublandlord, its employees, agents, contractors, visitors
or licensees in or about the Subleased Premises or (B) Sublandlord's failure to
perform any of the obligations imposed on it under the Prime Lease.

               (f) LIMITATION ON PRIME LANDLORD'S OBLIGATION. Notwithstanding
anything contained in this Sublease (including any provisions of the Prime Lease
which are incorporated by reference into this Sublease), Subtenant acknowledges
and agrees that except as specifically provided below Sublandlord shall have no
obligation, liability or responsibility whatsoever to Subtenant to provide or
perform any work, service, utility, repair, alteration, restoration or other
obligation as such items pertain to the Subleased Premises which Prime Landlord
is obliged to provide or perform pursuant to the provisions of the Prime Lease.
If Prime Landlord shall default or delay in providing or performing any such
work, service, utility, repair, alteration, restoration or other obligation as
such items pertain to the Subleased Premises,

<PAGE>

Sublandlord's only obligations to Subtenant on account thereof shall be (i) to
permit Subtenant, at its expense, to prosecute an action against Prime Landlord
for damages or specific performance for Subtenant's benefit in Sublandlord's
name, and (ii) to make a good faith effort and to reasonably cooperate with
Subtenant (at Subtenant's expense) in attempting to cause Prime Landlord to
provide or perform such service or obligation. Any condition resulting from such
default or delay by Prime Landlord shall not constitute an eviction, actual or
constructive, of Subtenant. No such default or delay shall excuse Subtenant from
the performance or observance of any of its obligations to be performed or
observed under this Sublease or shall entitle Subtenant to terminate this
Sublease or to any reduction in or abatement of the minimum rent or other
charges provided for in this Sublease; provided, however, if Sublandlord is
entitled to a reduction or abatement in the rent due under the Prime Lease, then
Subtenant shall be entitled to a pro-rata share of such reduction or abatement
based on Subtenant's Proportionate Share or, if less than all of the Subleased
Premises are affected, Subtenant shall be entitled to an abatement, deduction,
or set off based on the ratio of the square footage of the area of the Subleased
Premises affected by such default or delay to the square footage of the
Premises. In furtherance of the foregoing, to the extent permitted by law,
Subtenant does hereby waive any cause of action and any right to bring an action
against Sublandlord by reason of any act or omission of Prime Landlord under the
Prime Lease. If Subtenant shall undertake any action against Prime Landlord
pursuant to clause (i) of the second sentence of this Section 6(e), then (i) all
papers, pleadings and other aspects of such action shall be subject to
Sublandlord's approval, not to be unreasonably withheld, and (ii) Sublandlord
may participate in such action.

               (g) SUBLANDLORD'S OBLIGATIONS UNDER THE PRIME LEASE. Sublandlord
agrees that it shall pay all amounts due and perform all obligations required of
it under the Prime Lease in a timely manner. Sublandlord agrees that it shall
not amend, modify, terminate, or otherwise change the Prime Lease in any manner
which materially and adversely affects Subtenant or this Sublease without first
obtaining the approval of Subtenant, which approval shall not be unreasonably
withheld, delayed or conditioned. The parties agree that a denial of Subtenant's
consent shall not be unreasonable if the change in the Prime Lease results in
the imposition of an increased monetary burden on Subtenant.

          7. NOTICES. All statements and notices to be given under this Sublease
and the Prime Lease shall be in writing and given either (i) in person, (ii) by
certified mail, return receipt requested, postage paid, or (iii) overnight

              Void after 5:00 pm New York City Time, April 26, 2004

               WARRANT TO PURCHASE 481,434 SHARES OF COMMON STOCK

                                       OF

                            BLUESTONE SOFTWARE, INC.

         This is to certify that, FOR VALUE RECEIVED, BT ALEX. BROWN
INCORPORATED or its registered assigns pursuant to Section (d) hereof
("Holder"), is entitled to purchase, subject to the provisions of this
Warrant, from Bluestone Software, Inc. a Delaware corporation (the
"Company"), 481,434 fully paid, validly issued and nonassessable shares of
Common Stock, par value $0.001 per share, of the Company ("Common Stock"), at
the exercise price of $2.72 per share until 5:00 pm New York City time on
April 26, 2004. The number of shares of Common Stock to be received upon the
exercise of this Warrant and the price to be paid for each share of Common
Stock may be adjusted from time to time as hereinafter set forth. The shares
of Common Stock deliverable upon such exercise, and as adjusted from time to
time, are hereinafter sometimes referred to as "Warrant Shares," and the
exercise price of a share of Common Stock as adjusted from time to time is
hereinafter sometimes referred to as the "Exercise Price."

         (a) EXERCISE OF WARRANT. The Warrant may be exercised at any time,
or from time to time, until 5:00 pm New York City time on April 26, 2004 (the
"Expiration Date"), provided, however, that if such day is a day on which
banking institutions in the State of New York are authorized by law to close,
then on the next succeeding day which shall not be such a day. The Warrant
may be exercised by presentation and surrender hereof to the Company at its
principal office, or at the office of its stock transfer agent, if any, with
the Purchase Form annexed hereto duly executed (with signature guaranteed if
required by the Company or its stock transfer agent) and accompanied by
payment of the Exercise Price for the number of Warrant Shares specified in
such form and any applicable taxes. The purchase price for any Warrant Shares
purchased pursuant to the exercise of this Warrant shall be paid in full upon
such exercise in cash or by certified or bank check or pursuant to a cashless
exercise procedure whereby the Warrant Shares issued upon exercise of this
Warrant will be sold by the Holder or Holder's agent with Holder receiving
the difference between the Exercise Price and the sale price, in cash, and
the Company receiving the Exercise Price for the Warrant Shares, in cash, or
any combination of the foregoing methods of paying the Exercise Price. As
soon as practicable after each such exercise of the Warrants, but not later
than seven (7) business days from the date of such exercise, 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 the Holder's designee, except in the case of a cashless exercise.
If the Warrant should be exercised in part only, the Company shall, upon
surrender of the Warrant for cancellation, execute and deliver a new Warrant
evidencing the rights of the Holder thereof to purchase the balance of the
Warrant Shares purchasable thereunder. In the event of a cash exercise, upon
receipt by the

                                        1

<PAGE>



Company of the Warrant at its office, or by the stock transfer agent of the
Company at its office, in proper form for exercise, together with the exercise
price thereof and taxes as aforesaid in cash or certified or bank check and the
investment letter described below, the Holder shall be deemed to be the holder
of record of the shares of Common Stock issuable upon such exercise,
notwithstanding that the stock transfer books of the Company shall then be
closed or that certificates representing such shares of Common Stock shall not
then be physically delivered to the Holder. In order to assure the availability
of an exemption from registration under the federal or applicable state
securities laws, the Company may condition the exercise of the Warrant upon the
Holder delivering to the Company an investment letter in the form as customarily
used by the Company from time to time in connection with the exercise of
non-registered options and warrants which are issued by the Company. It is
further understood that certificates for the Warrant Shares, if any, to be
issued upon exercise of the Warrant may contain a restrictive legend in
accordance with Section (j) hereof.

         (b) RESERVATION OF SHARES. The Company shall at all times reserve for
issuance and/or delivery upon exercise of this Warrant such number of shares of
its Common Stock as shall be required for issuance and delivery upon exercise of
the Warrants. If the Common Stock is or becomes listed on any national
securities exchange or the NASDAQ National Market System, the Company shall also
list such shares on such exchange subject to notice of issuance or maintain the
listing of its Common Stock on the NASDAQ system, as the case may be.

         (c) FRACTIONAL SHARES. No fractional shares or scrip representing
fractional shares shall be issued upon the exercise of the Warrant. With respect
to any fraction of a share called for upon any exercise hereof, the Company
shall pay to the Holder an amount in cash equal to such fraction multiplied by
the current market value of a share, determined as follows:

                           (1) If the Common Stock is listed on a national
                  securities exchange or admitted to unlisted trading privileges
                  on such exchange or listed for trading on the NASDAQ National
                  Market System, the current market value shall be the last
                  reported sale price of the Common Stock on such exchange or
                  system on the last business day prior to the date of exercise
                  of this Warrant or if no such sale is made on such day, the
                  average closing bid and asked prices for such day on such
                  exchange or system;

                           (2) If the Common Stock is not so listed or admitted
                  to unlisted trading privileges, the current market value shall
                  be the mean of the last reported bid and asked prices reported
                  by the National Quotation Bureau, Inc., on the last business
                  day prior to the date of the exercise of this Warrant; or

                           (3) If the Common Stock is not so listed or admitted
                  to unlisted trading privileges and bid and asked prices are
                  not so reported, the current market value shall be an amount,
                  not less than the book value thereof as at the end of the most
                  recent fiscal year of the Company ending prior to the date of
                  the exercise of the Warrant,

                                        2

                  the Board of Directors of the Company.

         (d) EXCHANGE, TRANSFER, ASSIGNMENT OR LOSS OF WARRANT. The Warrant is
exchangeable, without expense, at the option of the Holder, upon presentation
and surrender hereof to the Company or at the office of its stock transfer
agent, if any, for other Warrants of different denominations entitling the
Holder thereof to purchase in the aggregate the same number of shares of Common
Stock purchasable hereunder. Subject to Section (j) hereof, the Holder may
transfer or assign the Warrant, in whole or in part and from time to time. Upon
surrender of this Warrant to the Company at its principal office or at the
office of its stock transfer agent, if any, with the Assignment Form annexed
hereto duly executed (with signature guaranteed, if required by the Company or
its stock transfer agent) and funds sufficient to pay any transfer tax, the
Company shall, without charge, execute and deliver a new Warrant in the name of
the assignee or assignees named in such instrument of assignment and this
Warrant shall promptly be canceled. This Warrant may be divided by or combined
with other Warrants which carry the same rights upon presentation hereof at the
principal office of the Company or at the office of its stock transfer agent, if
any, together with a written notice specifying the names and denominations in
which new Warrants are to be issued and signed by the Holder hereof. The term
"Warrant" as used herein includes any Warrants into which this Warrant my be
divided or exchanged. Upon receipt by the Company of evidence satisfactory to it
of the loss, theft, destruction or mutilation of this Warrant, and in the case
of loss, theft or destruction, of reasonable satisfactory indemnification, and
upon surrender and cancellation of this Warrant, if mutilated, the Company will
execute and deliver a new Warrant of like tenor, date and amount. Any such new
Warrant executed and delivered shall constitute a binding contractual obligation
on the part of the Company.

         (e) RIGHTS OF THE HOLDER. The Holder shall not, by virtue hereof, be
entitled to any rights of a shareholder in the Company, either at law or equity,
and the rights of the Holder are limited to those expressed in the Warrant and
are not enforceable against the Company except to the extent set forth herein.

         (f) ANTI-DILUTION PROVISIONS. So long as this Warrant shall be
outstanding, the Exercise Price in effect at any time and the number and kind of
securities purchasable upon the exercise of this Warrant shall be subject to
adjustment from time to time upon the happening of certain events as follows:

                           (1)      SPECIAL DEFINITIONS.  For purposes of this
                     Warrant, the following definitions apply:

                           (2) NO ADJUSTMENT OF EXERCISE PRICE. Any provision
                  herein to the contrary notwithstanding, no adjustment in the
                  Exercise Price shall be made in respect of: (i) any future
                  issuance of Options (or upon the issuance of Common Stock upon
                  the exercise of such Options) to employees of the Company

                  issuance of Additional Shares of Common Stock (as defined
                  herein) unless the consideration per share (determined
                  pursuant to Section (f)(5) herein) for the Additional Shares
                  of Common Stock issued or deemed to be issued by the Company

                  immediately prior to, such issue.

                           (3) DEEMED ISSUE OF ADDITIONAL SHARES OF COMMON
                  STOCK. In the event the Company at any time or from time to
                  time after the date hereof shall issue any Options or
                  Convertible Securities or shall fix a record date for the

                  entitled to receive any such Options or Convertible
                  Securities, then the maximum number of shares (as set forth in
                  the instrument relating thereto without regard to any
                  provisions contained therein designed to protect against
                  dilution) of Common Stock issuable upon the exercise of such
                  Options or, in the case of Convertible Securities and Options
                  therefor, upon the conversion or exercise of such Convertible
                  Securities and Options therefor, and the conversion or
                  exchange of such Convertible Securities, shall be deemed to be
                  Additional Shares of Common Stock issued as of the time of
                  such issue, or in case such a record date shall have been
                  fixed, as of the close of business on such record date,
                  provided that in any such case in which Additional Shares of
                  Common Stock are deemed to be issued:

                                            (A) no further adjustments in the
                                    Exercise Price shall be made upon the
                                    subsequent issue of Convertible Securities
                                    or shares of Common Stock upon the exercise
                                    of such Options or conversion or exchange of
                                    such Convertible Securities;

                                            (B) if such Options or Convertible
                                    Securities by their terms provide, with the
                                    passage of time or otherwise, for any
                                    increase or decrease in the consideration

                                    subsequent adjustments based thereon, shall,

                                    subsequent adjustments based thereon, shall,
                                    upon such expiration, be recomputed as if:

                                                     (1) in the case of

                                    Stock, the only Additional Shares of Common
                                    Stock issued were the shares of Common

                                    exercise of such Options or the conversion
                                    or exchange of such Convertible Securities
                                    and the consideration received therefor was
                                    the consideration actually received by the
                                    Company for the issue of all such Options,
                                    whether or not exercised, plus the
                                    consideration actually received by the
                                    Company upon such exercise, or for the issue
                                    of all such Convertible Securities which

                                    the additional consideration, if any,
                                    actually received by the Company upon such
                                    conversion or exchange; and

                                    Convertible Securities, if any, actually
                                    issued upon the exercise thereof were issued
                                    at the time of such Options, and the
                                    consideration received by the Company for
                                    the Additional Shares of Common Stock deemed
                                    to have been then issued was the

                                    Company for the issue of all such Options,
                                    whether or not exercised, plus the

                                    by the Company (determined pursuant to
                                    Section (f)(5) herein) upon the issue of the
                                    Convertible Securities with respect to which
                                    such Options were actually exercised;

                                    effect of increasing the Exercise Price to
                                    an amount which exceeds the lower of (a) the

                                            (E) in the case of any Options which
                                    expire by their terms not more than 30 days
                                    after the date of issue thereof, no
                                    adjustment of the Exercise Price shall be
                                    made until the expiration or exercise of all
                                    such Options, whereupon such adjustment
                                    shall be made in the same manner provided in
                                    clause (C) above.

                           (4) ADJUSTMENT OF EXERCISE PRICE UPON ISSUANCE OF
                  ADDITIONAL SHARES OF COMMON STOCK. In the event the Company,
                  at any time after the date herein, shall issue Additional
                  Shares of Common Stock (including Additional Shares of Common
                  Stock deemed to be issued pursuant to Section (f)(5) herein)
                  without consideration or for a consideration per share less
                  than the Exercise Price in effect on the date of and
                  immediately prior to such issue, then and in such event, the
                  Exercise Price under the Warrant shall be reduced concurrently
                  with such issue, to a price (calculated to the nearest cent)
                  determined by multiplying such Exercise Price by a fraction,
                  the numerator of which shall be the number of shares of Common
                  Stock outstanding immediately prior to such issue plus the
                  number of shares of Common Stock which the aggregate
                  consideration received by the Company for the total number of
                  Additional Shares of Common Stock so issued would purchase at
                  such Exercise Price in effect immediately prior to such
                  issuance, and the denominator of which shall be the number of
                  shares of Common Stock outstanding immediately prior to such
                  issue plus the number of such Additional Shares of Common
                  Stock so issued. For the purpose of the above calculation, the
                  number of shares of Common Stock outstanding immediately prior
                  to such issue shall be calculated as if all Warrants had been
                  exercised and all Convertible Securities had been fully
                  converted into shares of Common Stock immediately prior to
                  such issuance and any outstanding warrants, options or other
                  rights for the purchase of shares of stock or convertible
                  securities had been fully exercised immediately prior to such
                  issuance (and the resulting securities fully converted into
                  shares of Common Stock if so convertible) as of such date, but
                  not including in such calculation any additional shares of
                  Common Stock issuable with respect to this Warrant,
                  Convertible Securities, or outstanding options, warrants or
                  other rights for the purchase of shares of stock or
                  convertible securities, solely as a result of the adjustment
                  of the Exercise Price (or other conversion ratios) resulting
                  from the issuance of the Additional Shares of Common Stock
                  causing the adjustment in question.

                           (5) DETERMINATION OF CONSIDERATION. For purposes of
                  this Warrant, the consideration received by the Company for
                  the issue of any Additional Shares of Common Stock shall be
                  computed as follows:

                           (A) Cash and Property. Such consideration shall:

                                     (1) insofar as it consists of cash, be
                                     computed at the aggregate amount of cash
                                     received by the Company,

                                     excluding amounts paid or payable for
                                     accrued interest or accrued dividends;

                                     (2) insofar as it consists of property
                                     other than cash, be computed at the fair
                                     value thereof at the time of such issue, as
                                     determined in good faith by the Board; and

                                     (3) in the event Additional Shares of
                                     Common Stock are issued together with the
                                     other shares or securities or other assets
                                     of the Company for consideration which
                                     covers both types of securities, be the
                                     proportion of such consideration so
                                     received, computed as provided in
                                     clauses (1) and (2) above, with respect to
                                     the Additional Shares of Common Stock as
                                     determined in good faith by the Board.

                                 (B) Options and Convertible Securities. The
                                 consideration per share received by the Company
                                 for Additional Shares of Common Stock deemed to
                                 have been issued pursuant to Section (f)(5)
                                 herein, relating to Options and Convertible
                                 Securities shall be determined by dividing:

                                      (1) the total amount, if any, received or
                                      receivable by the Company as consideration
                                      for the issue of such Options or
                                      Convertible Securities, plus the minimum
                                      aggregate amount of additional
                                      consideration (as set forth in the
                                      instruments relating thereto, without
                                      regard to any provision contained therein
                                      designed to protect against dilution)
                                      payable to the Company upon the exercise
                                      of such Options or the conversion or
                                      exchange of such Convertible Securities,
                                      or in the case of Options for Convertible
                                      Securities, the exercise of such Options
                                      for Convertible Securities and the
                                      conversion or exchange of such Convertible
                                      Securities, by

                                      (2) the maximum number of shares of Common
                                      Stock (as set forth in the instruments
                                      relating thereto, without regard to any
                                      provision contained therein designed to
                                      protect against the dilution) issuable
                                      upon the exercise of such Options or
                                      conversion or exchange of such Convertible
                                      Securities.

                           (6) ADJUSTMENTS TO EXERCISE PRICE FOR STOCK DIVIDENDS
                  AND FOR COMBINATIONS OR SUBDIVISIONS OF COMMON STOCK. In the
                  event that the Company at any time or from time to time after
                  the date herein shall declare or pay, without consideration,
                  any dividend on the Common Stock payable in Common Stock or in

                                        8

<PAGE>



                  any right to acquire Common Stock for no consideration, or
                  shall effect a subdivision of the outstanding shares of Common
                  Stock into a greater number of shares of Common Stock (by
                  stock split, reclassification or otherwise than by payment of
                  a dividend in Common Stock or in any right to acquire Common
                  Stock), or in the event the outstanding shares of Common Stock
                  shall be combined or consolidated, by reclassification or
                  otherwise, into a lesser number of shares of Common Stock,
                  then the Exercise Price in effect immediately prior to such
                  event shall, concurrently with the effectiveness of such
                  event, be proportionately decreased or increased, as
                  appropriate. In the event that this Company shall declare or
                  pay, without consideration, any dividend on the Common Stock
                  payable in any right to acquire Common Stock for no
                  consideration, then the Company shall be deemed to have made a
                  dividend payable in Common Stock in an amount of shares equal
                  to the maximum number of shares issuable upon exercise of such
                  rights to acquire Common Stock.

                           (7) ADJUSTMENTS FOR RECLASSIFICATION AND
                  REORGANIZATION. If the Common Stock issuable upon the exercise
                  of the Warrants shall be changed into the same or a different
                  number of shares of any other class or classes of stock,
                  whether by capital reorganization, reclassification or
                  otherwise, the Exercise Price then in effect shall,
                  concurrently with the effectiveness of such reorganization or
                  reclassification, be proportionately adjusted so that the
                  Warrants shall be exercised for, in lieu of the number of
                  shares of Common Stock which the holders would otherwise have
                  been entitled to receive, a number of shares of such other
                  class or classes of stock equivalent to the number of shares
                  of Common Stock that would have been subject to receipt by the
                  holders upon the exercise of the Warrant immediately before
                  that change.

                           (8) No adjustment in the Exercise Price shall be
                  required unless such adjustment would require an increase or
                  decrease of at least $.05 in such price; provided, however,
                  that any adjustments which by reason of this subsection (f)
                  (8) are not required to be made shall be carried forward and
                  taken into account in any subsequent adjustment required to be
                  made hereunder.

                           (9) Whenever the Exercise Price is adjusted, as
                  herein provided, the Company shall promptly cause a notice
                  setting forth the adjusted Exercise Price and adjusted number
                  of Warrant Shares issuable upon exercise of each Warrant to be
                  mailed to the Holder, at its address appearing in the Warrant
                  Register, and shall cause a certified copy thereof to be
                  mailed to its transfer agent, if any.

                           (10) All calculations under this Section (f) shall be
                  made to the nearest cent or to the nearest Warrant Share, as
                  the case may be.

                           (11) In the event that at any time, as a result of an
                  adjustment made pursuant to this Section (f) above, the Holder
                  of this Warrant thereafter shall become entitled to receive
                  any shares of the Company, other than Common Stock, thereafter
                  the number of such other shares so receivable upon exercise of
                  this Warrant shall be subject to adjustment from time to time
                  in a manner and on terms as nearly equivalent as practicable
                  to the provisions with respect to the Common Stock contained
                  in subsection (A) above.

                           (12) Irrespective of any adjustments in the Exercise
                  Price or the number or kind of Warrant Shares purchasable upon
                  exercise of this Warrant, Warrants theretofore or thereafter
                  issued may continue to express the same price and number and
                  kind of shares as are stated in the similar Warrants initially
                  issuable pursuant to this Warrant.

         (g) OFFICER'S CERTIFICATE. Whenever the Exercise Price shall be
adjusted as required by the provisions of the foregoing Section, the Company
shall forthwith file in the custody of its Secretary or an Assistant Secretary
at its principal office and with its stock transfer agent, if any, an officer's
certificate showing the adjusted Exercise Price determined as herein provided,
setting forth in reasonable detail the facts requiring such adjustment,
including a statement of the number of additional shares of Common Stock, if
any, and such other facts as shall be necessary to show the reason for and the
manner of computing such adjustment. Each such officer's certificate shall be
made available at all reasonable times for inspection by the Holder or any
holder of a Warrant executed and/or delivered pursuant to Section (a) or Section
(d), and the Company shall, forthwith after each such adjustment, mail, by
certified mail, a copy of such certificate to the Holder or any such holder.

         (h) NOTICES TO WARRANT HOLDERS. So long as this Warrant shall be
outstanding, (i) if the Company shall pay any dividend or make any distribution
upon the Common Stock, or (ii) if the Company shall offer to the holders of
Common Stock for subscription or purchase by them any shares of any class or any
other rights, or (iii) if any capital reorganization of the Company,
reclassification of the capital stock of the Company, consolidation or merger of
the Company with or into another corporation, sale, lease or transfer of all or
substantially all of the property and assets of the Company to another
corporation, or voluntary or involuntary dissolution, liquidation or winding up
of the Company shall be effected, then in any such case, the Company shall cause
to be mailed by certified mail to the Holder or any holder of a Warrant executed
and/or delivered pursuant to Section (a) or Section (d), at least 15 days prior
to the date specified in (x) or (y) below, as the case may be, a notice
containing a brief description of the proposed action and stating the date on
which (x) a record is to be taken for the purpose of such dividend, distribution
or rights, or (y) such reclassification, reorganization, consolidation, merger,
conveyance, lease, dissolution, liquidation or winding up is to take place and
the date, if any is to be fixed, as of which the holders of Common Stock or
other securities shall receive cash or other property deliverable upon such
reclassification, reorganization, consolidation, merger, conveyance,
dissolution, liquidation or winding up.

         (i)      SECURITIES LAW COMPLIANCE

                           (1) The Holder of the Warrant, by acceptance hereof,
                  acknowledges that the Warrant and the shares of Common Stock
                  to be issued upon exercise hereof or conversion thereof are
                  being acquired solely for the Holder's own account and not as
                  a nominee for any other party, and for investment, and that
                  the Holder will not offer, sell, transfer, assign or otherwise
                  dispose of this Warrant or any shares of Common Stock to be
                  issued upon exercise hereof or conversion thereof except under
                  circumstances that will not result in a violation of the Act
                  or any state securities laws. Upon exercise of the Warrant,
                  the Holder shall, if requested by the Company, confirm in
                  writing, in a form satisfactory to the Company, that the
                  shares of Common Stock so purchased are being acquired solely
                  for the Holder's own account and not as a nominee for any
                  other party, for investment, and not with a view toward
                  distribution or resale.

                           (2) If appropriate, the Warrant and any Warrants
                  issued upon exercise or substitution or upon assignment or
                  transfer pursuant to Section (a) or Section (d), as the case
                  may be, and all shares of Common Stock issued upon exercise
                  hereof or conversion thereof shall be stamped or imprinted
                  with legends setting forth the restrictions on transfer
                  arising under applicable federal and state securities laws.

         (j)      REGISTRATION RIGHTS UNDER THE SECURITIES ACT OF 1933

                           (1) Commencing on the effective date of the first
                  registration statement for a public offering of securities of
                  the Company, the Company shall advise the Holder of the
                  Warrant or of the Warrant Shares or any then Holder of
                  Warrants or Warrant Shares (such persons being collectively
                  referred to herein as "Holders") by prompt written notice
                  prior to the filing of any registration statement or
                  post-effective amendment thereto ("Registration Statement")
                  under the Securities Act of 1933, as amended (the "Act"),
                  covering an underwritten public offering of equity securities
                  of the Company solely for cash in excess of $1,000,000 (other
                  than a Registration Statement initiated by a holder on Form
                  S-3, a registration relating solely to the sale of securities
                  to participants in a Company stock option, stock purchase or
                  similar plan or a SEC Rule 145 transaction, a registration on
                  any form which does not include substantially the same
                  information as would be required to be included in a
                  registration statement covering the sale of the Registrable
                  Securities (as defined in the Second Restated Investors'
                  Rights Agreement dated May 25, 1999, between the Company and
                  the investors signatory thereto) or a registration in which
                  the only Common Stock being registered in Common Stock
                  issuable upon conversion of debt securities that are also
                  being registered) and shall register in any such Registration
                  Statement the number of Warrant Shares that the Holder shall
                  notify the Company it desires to register and shall include in
                  any such Registration Statement such

                                       11

<PAGE>



                  information as may be required to permit a public offering of
                  such Warrant Shares by the Company's underwriter(s). The
                  Company shall supply prospectuses and other documents as the
                  Holder may reasonably request in order to facilitate the
                  public sale or other disposition of the Warrant Shares. The
                  Company shall bear the entire cost and expense of a
                  registration of securities initiated by it under this Section
                  (j)(1). The Holder shall, however, bear the fees of its own
                  counsel and any transfer taxes and underwriting discounts or
                  commissions applicable to the Warrant Shares sold by it. The
                  Company may include other securities in any such registration
                  statement. The Company shall do any and all other acts and
                  things which may be necessary or desirable to enable the
                  Holder to consummate the public sale or other disposition of
                  the Warrant Shares, and furnish indemnification in the manner
                  as set forth in Paragraph (2) (a) of this Section (j), but
                  shall not be required to qualify as a foreign corporation to
                  qualify the Warrant Shares for sale under the securities laws
                  of any state. The Holder shall furnish information and
                  indemnification as set forth in Paragraph (2) (b) of this
                  Section (j). All decisions as to whether and when to proceed
                  with any Registration Statement shall be made solely by the
                  Company.

                           Notwithstanding the foregoing paragraph, in the event
                  that there is an underwritten offering of the Company's
                  securities offered pursuant to said registration statement
                  pursuant to the immediately preceding Paragraph, the
                  underwriter(s) shall have the right to refuse to permit any
                  Warrant Shares, or to limit the amount of Warrant Shares, to
                  be sold by the Holder to such underwriter(s) as such
                  underwriter(s) may determine in its discretion, and the Holder
                  shall refrain from selling such remainder of its Warrant
                  Shares covered by such registration statement for a period not
                  exceeding 180 days following the effective date and shall also
                  refrain at any time when notified by the Company that an
                  amendment or supplement to the prospectus is required. The
                  Company shall not be obligated to keep any Registration
                  Statement effective for a total of more than 120 days or until
                  the distribution contemplated in the Registration Statement
                  has been completed, whichever occurs first.

                           2(a) Whenever pursuant to this Section (j) a
                  Registration Statement relating to the Warrant Shares is filed
                  under the Act, amended or supplemented, the Company will
                  indemnify and hold harmless each Holder of Warrant Shares
                  covered by such Registration Statement, amendment or
                  supplement (such Holder being hereinafter called the
                  "Distributing Holder"), and each person, if any who controls
                  (within the meaning of the Act) the Distributing Holder,
                  against any losses, claims, damages or liabilities, joint or
                  several, to which the Distributing Holder or any such
                  controlling person may become subject, under the Act or
                  otherwise, insofar as such losses, claims, damages or
                  liabilities (or actions in respect thereof) arise out of or
                  are based upon any untrue statement or alleged untrue
                  statement of any material fact contained in any such
                  Registration Statement or any preliminary prospectus or final
                  prospectus constituting a part thereof or any amendment or
                  supplement thereto, or

                                       12

<PAGE>



                  arise out of or are based upon the omission to state therein a
                  material fact required to be stated therein or necessary to
                  make the statements therein not misleading; and will reimburse
                  the Distributing Holder and each such controlling person for
                  any legal or other expenses reasonably incurred by the
                  Distributing Holder and each controlling person for any legal
                  or other expenses reasonable incurred by the Distributing
                  Holder or such controlling person or underwriter in connection
                  with investigating or defending any such loss, claim, damage,
                  liability or action; provided, however, that the Company will
                  not be liable in any such case to the extent that any such
                  loss, claim, damage or liability arises out of or is based
                  upon an untrue statement or alleged untrue statement or
                  omission or alleged omission made in said Registration
                  Statement, preliminary prospectus, final prospectus or
                  amendment or supplement, in reliance upon and in conformity
                  with written information furnished by the Distributing Holder
                  or underwriter for use in the preparation thereof.

                           (b) The Distributing Holder will indemnify and hold
                  harmless the Company, each of its directors, each of its
                  officers who have signed said Registration Statement and such
                  amendments and supplements thereto, each person, if any, who
                  controls the Company (within the meaning of the Act) and the
                  Company's underwriter(s) and each person, if any, who controls
                  such underwriter(s) (within the meaning of the Act) against
                  any losses, claims, damages or liabilities to which the
                  Company or any such director, officer, underwriter or
                  controlling person may become subject, under the Act or
                  otherwise, insofar as such losses, claims, damages or
                  liabilities arise out of or are based upon any untrue or
                  alleged untrue statement of any material fact contained in
                  said Registration Statement, preliminary prospectus, final
                  prospectus, or amendment or supplement, or arise out of or are
                  based upon the omission or the alleged omission to state
                  therein a material fact required to be stated therein or
                  necessary to make the statements therein not misleading, in
                  each case to the extent, but only to the extent that such
                  untrue statement or alleged untrue statement or omission or
                  alleged omission was made in said Registration Statement,
                  preliminary prospectus, final prospectus or amendment or
                  supplement, in reliance upon and in conformity with written
                  information furnished by such Distributing Holder for use in
                  the preparation thereof; and will reimburse the Company or
                  underwriter or any such director, officer or controlling
                  person for any legal or other expenses reasonably incurred by
                  them in connection with investigating or defending any such
                  loss, claim, damage, liability or action.

                           (c) Promptly after receipt by an indemnified party
                  under this Paragraph 2 of notice of the commencement of any
                  action, such indemnified party will, if a claim in respect
                  thereof is to be made against any indemnifying party, give the
                  indemnifying party notice of the commencement thereof; but the
                  omission so to notify the indemnifying party will not relieve
                  it from any liability which it may have to any indemnified
                  party otherwise than under this Paragraph 2.


                                       13

<PAGE>



                           (d) In case any such action is brought against any
                  indemnified party, and it notifies an indemnifying party of
                  the commencement thereof, the indemnifying party will be
                  entitled to participate in, and, the extent that it may wish,
                  jointly with any other indemnifying party similarly notified
                  to assume the defense thereof, with counsel reasonably
                  satisfactory to such indemnified party, and after notice from
                  the indemnifying party to such indemnified party of its
                  election so to assume the defense thereof, the indemnifying
                  party will not be liable to such indemnified party under this
                  Paragraph 2 for any legal or other expenses subsequently
                  incurred by such indemnified party in connection with the
                  defense thereof other than reasonable costs of investigation.

                           (e) The Company's agreements with respect to Warrant
                  Shares in this Section (j) shall continue in effect regardless
                  of the exercise of the Warrant; provided, however, that the
                  Holder's rights under this Section (j) may not be assigned
                  without the prior written consent of the Company.

         (k)      RIGHT TO CONVERT WARRANT INTO COMMON STOCK.

                           (1) RIGHT TO CONVERT. The Holder shall have the right
                  to require the Company to convert this Warrant provided in
                  this Section (1), into common stock (the "Net Conversion
                  Right"). Upon exercise of the Net Conversion Right, the
                  Company shall deliver to the Holder (without payment by the
                  Holder of any Exercise Price or of any other cash or
                  consideration) that number of shares of Common Stock equal to
                  the quotient obtained by dividing (x) the value of this
                  Warrant at the time the Conversion Right is exercised
                  (determined by subtracting the aggregate Exercise Price in
                  effect immediately prior to the exercise of the Conversion
                  Right from the aggregate fair market value of the shares of
                  Common Stock issuable upon exercise of this Warrant
                  immediately prior to the exercise of the Conversion Right) by
                  (y) the fair market value of one share of Common Stock
                  immediately prior to the exercise of the Conversion Right.

                           (2) METHOD OF EXERCISE. The Net Conversion Right may
                  be exercised by the Holder by the surrender of this Warrant at
                  the principal office of the Company together with a written
                  statement specifying that the Holder thereby intends to
                  exercise the Net Conversion Right. Certificates for the shares
                  of Common Stock issuable upon exercise of the Net Conversion
                  Right shall be delivered to the Holder within five (5) days
                  following the Company's receipt of this Warrant together with
                  the aforesaid written statement.

                           (3) DETERMINATION OF FAIR MARKET VALUE. For purposes
                  of this Section (f), fair market value of a share of Common
                  Stock as of a particular date (the "Determination Date") shall
                  be determined in accordance with Section (c) of this Warrant.

         (l) AMENDMENTS. Neither the Warrant nor any term hereof may be changed,
waived, discharged or terminated without the prior written consent of the
Holder.

         (m) NO IMPAIRMENT. The Company will not avoid or seek to avoid the
observance or performance of any of the terms to be observed or performed
hereunder by the Company, but will at all times in good faith assist in the
carrying out of all the provisions of this Warrant and in the taking of all such
action as may be necessary or appropriate in order to protect the rights of any

         (n) GOVERNING LAW. This Agreement shall be governed by and construed
under the laws of the State of Delaware.

hereunder shall be in writing and shall be mailed by first class mail, postage
prepaid, addressed (a) if to the Holder, to BT Alex. Incorporated, One South

                                                         Exhibit 10.38

                           STOCK REPURCHASE AGREEMENT


         THIS AGREEMENT is made on the 18th day of April, 1997 by and between
Bluestone Software, Inc., a Delaware corporation (the "Company"), and Mel Baiada
(the "Stockholder").

                                   BACKGROUND

         WHEREAS, the Stockholder is the holder of 9,000,000 shares (the "Base
Shares") of common stock, $.001 par value per share, of the Company ("Common
Stock");

         WHEREAS, certain investors (the "Investors") and the Stockholder are
acquiring an aggregate of approximately $5,250,000 worth of shares of Series A
Convertible Preferred Stock, $.001 par value per share, of the Company
("Preferred Stock") pursuant to the terms of a Series A Preferred Stock Purchase
Agreement dated the date hereof among the Company, the Investors and the
Stockholder (the "Purchase Agreement"); and

         WHEREAS, it is a condition to the obligations of the Investors under
the Purchase Agreement that this Agreement be executed by the parties hereto,
and the parties are willing to execute this Agreement;

                                      TERMS

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

         Section 1.     DEFINITIONS.

                  As used in this Agreement, the following terms shall have the
following respective meanings:

                  "CONTINGENT SHARES" as of any date shall mean the number of
shares of Common Stock that are held by the Stockholder and that are designated
as "Contingent Shares" on the table set forth in Exhibit A attached hereto;
provided that no additional Contingent Shares shall become Vested Shares after
the date upon which the Stockholder shall cease to be employed by the Company
and its subsidiaries. The numbers of Shares referred to in the preceding
sentence shall be appropriately adjusted in the event of any stock split, stock
dividend or the like affecting the number of issued and outstanding shares of
Common Stock.

                  "VESTED SHARES" as of any date shall mean the number of shares
of Common Stock that are held by the Stockholder, that were formerly Contingent
Shares and that are designated as "Vested Shares" under the table in Exhibit A;
provided that no additional Contingent Shares shall become Vested Shares after
the date upon which the Stockholder shall



<PAGE>


cease to be employed by the Company and its subsidiaries. The numbers of Vested
Shares referred to in the preceding sentence shall be appropriately adjusted in
the event of any stock split, stock dividend or the like affecting the number of
issued and outstanding shares of Common Stock.

                  "OTHER SHARES" shall mean any shares of the capital stock of
the Company that are held by the Stockholder and that are neither Contingent
Shares nor Vested Shares.

         Section 2.     PROHIBITED TRANSFERS. The Stockholder shall not sell,
assign, transfer, pledge, hypothecate, mortgage, encumber or otherwise dispose
of any or all of the Contingent Shares without the prior written consent of
Company in its sole discretion. The preceding sentence shall not restrict any
Vested Shares or Other Shares; provided that any transfer by the Stockholder of
Vested Shares or Other Shares shall be made subject to and in accordance with
the provisions of the Purchase Agreement, a certain Voting Agreement of even
date herewith among the Company and the Investors, the Stockholder and the other
stockholders listed therein (the "Voting Agreement"), and a certain First
Refusal and Co-Sale Agreement of even date herewith among the Company, the
Investors, the Stockholder and the other parties thereto (the "First Refusal
Agreement").

         Section 3.     OPTION OF COMPANY UPON TERMINATION OF EMPLOYMENT.

         a    If the Stockholder ceases to be an employee of the Company and its
              subsidiaries for any reason other than the death or disability of
              the Stockholder, then the Company may, within sixty (60) days from
              the date upon which the Stockholder shall so cease to be employed,
              exercise the Company's option under this Section 3 to purchase
              from the Stockholder all, but not less than all, of the Contingent
              Shares as of the date upon which the Stockholder shall so cease to
              be employed (the "Termination Date"). For the purposes of this
              Agreement, "disability" shall have the meaning ascribed to such
              term in the Executive Employment Agreement dated April __, 1997
              between the Stockholder and the Company.

         b    The purchase price per share of the Contingent Shares for which
              the Company exercises its option under this Section 3 (the "Option
              Price") shall be the price per share that the Board of Directors
              of the Company determines is the fair market value per share of
              the Common Stock in connection with granting of stock options in
              the Company to the employees of the Company on or about the date
              hereof (such price being subject to equitable adjustment for any
              stock split, stock dividend, combination of shares or the like and
              based upon Common Stock).

         c    If the Company desires to exercise the Company's option to
              purchase, then the Company shall do so by communicating in writing
              the Company's election to purchase to the Stockholder, which
              communication shall state the then current number of Contingent
              Shares to be purchased by the Company and the aggregate

                                       -2-

<PAGE>


              Option Price and shall be given to the Stockholder in accordance
              with Section 8(a) below within the 60-day period provided for in
              Section 3(a). The sale of the Contingent Shares to be sold to the
              Company pursuant to this Section 3 shall be made at the offices of
              the Company on the 20th day following the date of the Company's
              written election to purchase (or if such 20th day is not a
              business day, then on the next succeeding business day). Such sale
              shall be effected by the Stockholder's delivery to the Company of
              a certificate or certificates evidencing the Contingent Shares to
              be purchased by the Company, duly endorsed for transfer to the
              Company, against payment to the Stockholder by the Company in cash
              in an amount equal to (i) the Option Price, multiplied by (ii) the
              number of Contingent Shares to be purchased by the Company (the
              "Purchase Price").

         d    Any action requiring the consent or election by the Company under
              this Agreement shall require the approval of a majority of the
              Board of Directors of the Company.

         Section 4.     TERM.

         a    The rights of the Company under this Agreement and the correlative
              obligations of the Stockholder with respect to the Company shall
              terminate upon the first to occur of:

                  (i) the fourth (4th) anniversary of this Agreement, provided
that the Stockholder is employed by the Company or one of its subsidiaries on
such date; or

                  (ii) at such time as the Stockholder shall no longer be the
owner of any Contingent Shares.

         Section 5.     FAILURE TO DELIVER SHARES. If the Stockholder becomes
obligated to sell the Contingent Shares to the Company under this Agreement and
fails to deliver the Contingent Shares in accordance with the terms of this
Agreement, then the Company may, at the Company's option and in addition to all
other remedies the Company may have, send to the Stockholder the Purchase Price
for the Contingent Shares as is herein specified. Thereupon, the Company upon
written notice to the Stockholder (a) shall cancel on the Company's books the
certificate or certificates representing the Contingent Shares to be sold and
(b) shall issue to the Stockholder a certificate or certificates evidencing the
number of Vested Shares, if any, registered in the name of the Stockholder, and
thereupon all of the Stockholder's rights in and to such Contingent Shares shall
terminate.

         Section 6.     SPECIFIC ENFORCEMENT.  The Stockholder expressly agrees
that the Investors and the Company will be irreparably damaged if this Agreement
is not specifically enforced. Upon a breach or threatened breach of the terms,
covenants and/or conditions of this Agreement by the Stockholder, the Investors
and the Company shall, in addition to all other remedies, each

                                       -3-

<PAGE>


be entitled to a temporary or permanent injunction, without showing any actual
damage, and/or a decree for specific performance, in accordance with the
provisions hereof.

         Section 7.     ISSUANCE OF SHARE CERTIFICATES AT CLOSING; LEGEND
                        REQUIREMENTS; REISSUANCE OF SHARES.

         a    At the closing contemplated by the Purchase Agreement, the
              Stockholder shall deliver to the Company for cancellation the
              certificate evidencing the Base Shares, and in consideration
              therefor, the Company shall issue to the Stockholder (i) a
              certificate or certificates evidencing the Other Shares, and (ii)
              a certificate or certificates evidencing the Contingent Shares, in
              each case duly registered in the name of the Stockholder and duly
              executed by the Company.

         b    Each certificate representing the Contingent Shares owned by the
              Stockholder shall be endorsed with the following legend:

              "THE SALE OR TRANSFER OF THE SECURITIES REPRESENTED BY THIS
              CERTIFICATE IS SUBJECT TO THE TERMS AND CONDITIONS OF A CERTAIN
              STOCK RESTRICTION AGREEMENT BY AND AMONG THE REGISTERED HOLDER (OR
              HIS PREDECESSOR IN INTEREST) AND BLUESTONE SOFTWARE, INC. A COPY
              OF SUCH AGREEMENT IS ON THE FILE AT THE PRINCIPAL OFFICE OF THE
              COMPANY."

         c    The Section 7(b) legend shall be removed by the Company: (i) with
              respect to Vested Shares, at the request of the Stockholder from
              time to time; and (ii) with respect to Contingent Shares, upon
              termination of this Agreement in accordance with the provisions of
              Section 4.

         d    From time to time as the Contingent Shares become Vested Shares,
              the Stockholder may deliver to the Company any certificates
              evidencing such Vested Shares, and the Company shall accept such
              certificates for cancellation, and reissue certificates evidencing
              such Vested Shares, in an amount adjusted to reflect the number of
              such Vested Shares, and certificates representing the number of
              Contingent Shares as of such date of issuance, in each case duly
              registered in the name of the Stockholder and duly executed by the
              Company.

         Section 8.     MISCELLANEOUS PROVISIONS.

         a    Unless otherwise provided, all notices, consents or other
              communications required or permitted to be given under this
              Agreement shall be in writing and shall be deemed to have been
              duly given (i) when delivered personally, (ii) three (3) business
              days after being mailed by first class mail, postage prepaid, or

              may also be given by prepaid telegram or facsimile and shall be
              effective on the date transmitted if confirmed within 24 hours
              thereafter by a signed original sent in the manner provided in the
              preceding sentence. Any party may change its address for notice
              and the address to which copies must be sent by giving notice of
              the new addresses to the other parties in accordance with this
              Section 8(a), except that any such change of address notice shall
              not be effective unless and until received.

         b    SEVERABILITY. In the event one or more of the provisions of this
              Agreement should, for any reason, be held to be invalid, illegal
              or unenforceable in any respect, such invalidity, illegality or
              unenforceability shall not affect any other provisions of this
              Agreement, and this Agreement shall be construed and interpreted
              in such manner as to be effective and valid under applicable law.

         c    WAIVER OR MODIFICATION. Any amendment or modification of this
              Agreement shall be effective only if evidenced by a written
              instrument executed by the Company and the Stockholder or their
              assignees.

         Section 9.     GOVERNING LAW. This Agreement shall be governed by and
