ITEM 1. BUSINESS

OUR COMPANY

    We believe 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. This
belief is based on our product performance and what we believe to be our
relative share of the fragmented market for application server software. 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 Suite, which represents a new generation of specialized Web application
server focused on commerce via the Internet. In December 1999, we released
Bluestone Total-e-Business, an e-business platform that provides the
infrastructure, integration, content management, personalization and e-commerce
components that companies utilize to conduct their businesses on the Internet.
In December 1999, at the Giga Information Group's Emerging Technology
Conference, we performed a live demonstration of our Total-e-Business solution,
integrating the Internet, Web application servers and wireless technology. We
were awarded a "best of" category win in the competition for this demonstration.

    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 ELECTRONIC BUSINESS ENABLEMENT. In this market sector,
      enterprises that wish to use the Internet as a means for conducting
      business, utilize our products:

       - as an infrastructure for performance, scalability and fault tolerance;

       - as a basis for application integration, internally and externally;

       - to manage and deliver content dynamically;

       - to maintain a profile for every user, customer, partner and vendor and
         to deliver information to each of them in a personalized format; and

       - as the standards-based e-commerce platform, including components such
         as catalogues, shopping carts, credit card authorization, shipping and
         taxation systems.

                                       1
<PAGE>
    Our solutions are used by some of the world's leading companies, including
ARI, Avnet, Deutsche Bank, Expression Engines, Inc., Food.com, gazoontite.com,
Hewlett-Packard, Houghton Mifflin Company, Sanchez Computer Associates,
Spinrocket.com, Inc. and Strategic Weather Services.

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., an independent research organization, 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
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.

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;

    - the ability to effectively monitor and manage Web-based applications and
      infrastructure;

    - the ability to dynamically deliver content and manage that content based
      on attributes and weighting factors;

    - the ability to deliver content to individuals based on their own unique
      needs and attributes and to personalize that delivery; and

    - the ability to incorporate e-commerce components seamlessly into the
      corporate environment to satisfy the demands of the new business model
      centered on the Internet.

    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;

                                       2
<PAGE>
    - 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.

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; integrate their
corporate systems internally and with those of their partners and vendors;
identify, manage and dynamically deliver information; personalize and analyze
interaction with users, customers, partners and vendors; and utilize
commercially available e-commerce components to 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 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

                                       3
<PAGE>
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 by the release of our
Bluestone XML Suite, and our early entry as an e-business platform provider with
our Total-e-Business Suite 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. New enhancements to our stable of products consist of
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. In December 1999, we released a new product
line called Total-e-Business which is a new category of software referred to as
an e-business platform. Total-e-Business combines our JAVA Web application
infrastructure, our XML integration server, content management both from
Bluestone and complementary software providers, delivery personalization based
on dynamic user profile and analysis, and easy access to standard industry
e-commerce components. 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. At the December 1999 Emerging
Technology Conference sponsored by Giga Information Group, we performed a live
demonstration integrating the Internet, Web application servers and wireless
technology. Consequently, we believe that we are uniquely positioned as a
performance leader and innovator in our industry and will benefit as an
increasing number of large mission-critical systems move to the Web and as
Internet commerce and e-business 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

                                       4
<PAGE>
telecommunications, insurance, brokerage, pharmaceuticals, e-commerce and
e-business most easily identified by their Internet initiatives. We intend to
increase the number of field sales offices and field sales representatives over
the next 12 months. Our direct sales organization is primarily organized around
geographic regions. As of December 31, 1999, we had 79 employees in sales and
marketing, 32 of which were quota-carrying field and inside 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 Computer Associates;

    - 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.

    MAKE STRATEGIC ACQUISITIONS OF COMPLEMENTARY BUSINESSES AND
TECHNOLOGIES.  An element of our growth strategy is to make selected, strategic
acquisitions of businesses and technology to consolidate our position as a
leading provider of complete e-business solutions. We intend to pursue
acquisitions that we believe will increase market share, expand product and
service capabilities, obtain key human resources and technical expertise and
generate greater critical mass and market presence.

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.

    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 Total-e-Business, Sapphire/Web and XML Suite solutions.

    We offer extensive training and certification for all of our 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 December 31, 1999, our sales and marketing organization consisted of
79 individuals, all of whom were based in North America. We had 22 field sales
representatives and 10 inside sales representatives, all of whom carry quotas.

    The sales force is comprised of two primary organizations: 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,
San Francisco, Toronto, Boston, New York, Philadelphia 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 eight 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

                                       7
<PAGE>
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, Sanchez Computer Associates and Sun Microsystems, among
others.

    We have relationships with independent software vendors, including
Hewlett-Packard, Computer Associates, 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.

    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 1999, we licensed copies of our Sapphire/Web, XML Suite
and Total-e-Business 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, and broadening their usage of these
Web-enabled applications to include business-to-business and
business-to-consumer interactions.

    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
presently 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, Avnet, Deutsche Bank, Expression Engines, Inc.,
Food.com, gazoontite.com, Hewlett-Packard, Houghton Mifflin Company, Sanchez
Computer Associates, Spinrocket.com, Inc. and Strategic Weather Services. Each
of these customers has accounted for at least $100,000 in revenue.

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

                                       8
<PAGE>
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 focused on two areas:

    - fundamental infrastructure for deploying and managing large, mission
      critical applications; and

    - implementing solutions for e-business on standards-based platforms.

    Specific technology features of the Bluestone solution include:

    100% PURE JAVA APPLICATION SERVER.  The JAVA platform offers enormous
benefits to our customers and us. 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 AS/400 computers. JAVA
has also brought large productivity gains to our development team by decreasing
development time, eliminating porting costs and speeding time to market.

    J2EE PLATFORM.  Bluestone's product families are built on the J2EE platform.
This means that thousands of developers working on this platform are all
creating software that integrates and runs with the Bluestone environment.
Bluestone provides value added capabilities on top of the J2EE environment to
increase the scalability, fault tolerance and management of applications, while
providing tools and components that allow for complete solutions to the
e-business needs of our customers. Customers are able to build applications
faster using the combination of JAVA Server Pages, Java Beans, Enterprise JAVA
Beans and leveraging Bluestone's XML capabilities.

    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 our application servers 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

                                       9
<PAGE>
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 also contributes to fault tolerance by
working in conjunction with the persistent state server.

    BLUESTONE XML-SERVER COMMUNICATIONS SERVICES.  This program recognizes the
protocol of incoming communications and translates it to a request for service
to the Bluestone XML-Server. XML documents can be passed to and from the
Bluestone 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.

    HOT VERSIONING AND HOT SWAPPING.  These capabilities 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. Our application servers also
support 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.

    DYNAMIC CONTENT MANAGEMENT.  The new Total-e-Business product meets
customers' needs for dynamically creating Web pages. This capability is built on
the open J2EE platform and leverages the XML standard to provide an open,
flexible and scaleable solution to creating a complex Web site.

    PERSONALIZATION.  Total-e-Business includes the ability to customize content
depending on the individual. Bluestone has created a powerful, open approach for
personalization built on standards and

                                       10
<PAGE>
XML. We offer our customers multiple methods to meet their varied
personalization needs from collaborative filtering to declarative rules.

    XML RULES ENGINE.  One of the methods of personalization allows for business
managers to declare rules specifying the type of content for different
categories of users--for example senior citizen discounts or promotion of
overstocked inventory. Bluestone has created a rules engine that we believe to
be unique in the industry by using XML as the design and specification language
for all rules. The rules engine compiles the rules into JAVA Servlets that
execute very fast, so that multiple rules may be used to customize content for
each user of a Web site. This provides Web developers with the power to provide
flexible, customized sites controlled by the business manager.

    E-COMMERCE COMPONENTS.  Bluestone Total-e-Business is packaged with a set of
e-commerce components built for easy reuse by customers. These components
include catalog, searching, shopping cart, shipping, taxation and others. The
components are 100% Pure JAVA and include an XML interface for ease of use by
HTML developers responsible for the look and feel of a site. Bluestone's early
adoption of XML technology has benefited our design and reuse of these
components.

PRODUCT DEVELOPMENT

    Historically, we have invested heavily in product development. We incurred
product development expenses of $1.3 million, $2.5 million and $4.5 million in
1997, 1998 and 1999, respectively. 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 December 31, 1999, we had 42 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 facility 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
benefited from a very low turnover rate.

    We are currently developing new releases to our Total-e-Business,
Sapphire/Web and XML product families. We anticipate that these new releases
will enable more effective business-to-consumer and business-to-business
e-commerce, through high-end management and ease of use capabilities.
Furthermore, we intend to develop 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 December 31, 1999, we had 190 employees, of which 79 were employed in
sales and marketing, 32 were employed in services, 42 were employed in product
development and 37 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.

    On September 23, 1999, the Securities and Exchange Commission declared
effective our registration statement on Form S-1 (File No. 333-82213) relating
to our initial public offering of our common stock. We received net proceeds of
approximately $54.8 million after deducting underwriting discounts and offering
expenses. Although, we cannot distinguish the net proceeds from our initial
public offering from the net proceeds from our prior financing activities or
other cash on hand at September 30, 1999, we used $4.3 million in cash for
operating activities since September 30, 1999 (approximately the date of closing
of our initial public offering) and believe that approximately 66% of such
amount was used for sales and marketing activities, 18% was used for product
development and 16% was used for general corporate purposes.

    We incorporate herein by reference information concerning our sales of
unregistered securities during 1999 from Item 15 of Part II of our registration

ITEM 7. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL POSITION 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.

                                       14
<PAGE>
    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. 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 Suite, 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.
In December 1999, we released Bluestone Total-e-Business. For the year ended
December 31, 1999, all of our revenue was generated from our proprietary
software products and related services.

OVERVIEW

    Our fiscal year end is December 31. References to 1997, 1998 or 1999 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 during 1999, one customer accounted for greater than 10% of our
total product and services revenues. Our top 10 customers represented 34%, 39%
and 50% of total revenues in 1997, 1998 and 1999, respectively. In the future,
we expect to continue to have individual customers account for a significant
portion of our revenue during a given period.

    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 generally
based on the number of developer seats and server interactions. Pricing options
based on enterprise-wide deployment or the number of processors is also
available. We also sell annual and multi-year licenses to independent software
vendors that allow for the integration of our products into their software. We
generally require a written license contract that typically provides for payment
within 30-60 days of contract signing. Certain multi-year license contracts
contain payment terms that extend beyond one year. Pursuant to the American
Institute of Certified Public Accountants' Statement of Position 97-2, any
amounts due under contracts beyond one year are not deemed to be fixed or
determinable and therefore are deferred and recognized as revenue when the
payments become due.

                                       15
<PAGE>
    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 or
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 licenses also includes the cost of
third-party software products embedded in our product offerings.

    COST OF SERVICES.  Cost of services consists primarily of salary and benefit
costs of our consulting, support and training organizations, and are expensed
when incurred. We also engage outside consultants to meet customer demand.

    SALES AND MARKETING.  We license our products primarily through our indirect
channels and our 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 corporate, 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>

1999 COMPARED TO 1998

SOFTWARE LICENSE FEES

    License fees were $11.7 million and $3.4 million for the years ended
December 31, 1999 and 1998, respectively. This increase of 243.7% was primarily
due to a shift in our product position from a low-priced development tool to a
high-end, higher-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 the licensing of our graphical user interface product line in
April 1998.

SERVICES REVENUE

    Services revenue was $4.0 million and $3.6 million for 1999 and 1998,
respectively. Services revenue increased 10.3% between the two periods. This
relatively small increase in services revenue when compared to the increase in
software license fees was primarily 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 less than two weeks in duration, rather than long-term
implementation activities. Larger scale implementation activities currently are
performed primarily by systems integrators with which we have strategic
alliances.

                                       17
<PAGE>
THIRD PARTY PRODUCTS AND RELATED SERVICES REVENUE

    Third party products and related services revenue was zero and $1.1 million
for the years ended December 31, 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 96.6% for 1999 from 92.4% in 1998.
This increase was primarily due to the increase in revenue per customer. Our
focus on positioning our Sapphire/Web family of products as enterprise-wide
solutions has increased the revenue associated with each sale, while the cost of
sales for the product has decreased, as we have reduced our printing and
duplication costs associated with our products and related documentation.
However, in future periods, as we continue to enhance our product offerings, the
license fee gross margin may decrease as a result of the cost of third-party
software embedded in our software products.

GROSS MARGIN-SERVICES REVENUE

    Our services gross margin remained relatively flat at (20.0)% for 1999 and
(22.5)% in 1998. Our negative services gross margins are 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 $15.9 million and $9.6 million for 1999
and 1998, respectively, representing an increase of 66.9%. Of this increase,
$1.8 million was due to increases in payroll and related costs, $796,000 was due
to recruiting costs and travel costs as a result of the growth in the number of
sales personnel, $1.1 million was due to increased advertising and trade show
expenses and $1.3 million 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 1999 was 59 compared to 49 for 1998. We also
incurred increases in variable marketing expenses due to increased channels and
customer marketing, direct mail campaigns and public relations expenses in order
to increase market awareness and gain market acceptance of our products. These
costs as a percentage of revenue were 101.8% and 117.7% for 1999 and 1998,
respectively.

PRODUCT DEVELOPMENT

    Product development expenses were $4.5 million and $2.5 million for 1999 and
1998, respectively, representing an increase of 83.4%. This increase is
primarily due to increased payroll and related costs of $1.6 million associated
with the development of our new products, Sapphire/Web Release 6, Bluestone XML
Suite and Bluestone Total-e-Business. We believe that our product development
investment is essential for us to maintain our market and technological
competitiveness. These costs as a percentage of revenue were 29.0% and 30.5% for
1999 and 1998, respectively. Average development headcount for the years ended
December 31, 1999 and 1998 was 33 and 21, respectively.

GENERAL AND ADMINISTRATIVE

    General and administrative expenses were $4.4 million and $2.3 million for
1999 and 1998, respectively. Included in expenses for 1999 were $577,000 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

                                       18
<PAGE>
and administrative expenses were $3.8 million, an increase of 65.6% over 1998.
This increase was primarily due to increased payroll and related costs of
$645,000 resulting from the addition of personnel to support the growth of our
business as well as increased professional fees and insurance costs. General and
administrative expenses as a percentage of revenue were 28.2% and 28.5% for the
years ended December 31, 1999 and 1998, respectively. Excluding these severance
and consulting costs, the expenses as a percentage of revenue decreased to 24.5%
for 1999.

AMORTIZATION OF STOCK-BASED COMPENSATION

    Amortization of stock-based compensation was $282,000 and zero for 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
the appointment of directors during the second quarter of 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 December 31, 1999, we had an aggregate of $1.1 million of deferred
compensation to be amortized through June 30, 2003.

INTEREST EXPENSE, NET

    Net interest expense was $406,000 for 1999 and $47,000 for 1998. This
additional expense in 1999 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
second quarter of 1999 based upon the fair value of the warrants at the dates of
issuance. The warrants are recorded as a component of stockholders' equity. This
$1.1 million of expense during 1999 was offset by interest income earned on the
proceeds from our initial public offering in September 1999 and our Series C
preferred stock financing in May 1999.

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 in 1998 to curtail the sale of third party products and services.

GROSS MARGIN-LICENSE FEES

    Our license fee gross margin was 92.4% in 1998 and 91.4% in 1997, remaining
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.

                                       19
<PAGE>
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 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, representing 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.

LIQUIDITY AND CAPITAL RESOURCES

    In September 1999, we completed the initial public offering of 4,000,000
shares of our common stock, realizing net proceeds from the offering of
$54.8 million. Prior to the offering, we financed our operations and met our
capital expenditure requirements primarily through sales of preferred stock,
bank loans, equipment loans and funds generated from operations. 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 our business. As of December 31, 1999, our primary
sources of liquidity consisted of cash and cash equivalents of approximately
$66.2 million and available borrowings of approximately $1.6 million under our
revolving line of credit, which is secured by substantially all of our assets.
As of December 31, 1999, we did not have an outstanding balance on our line of
credit. During December 1999, we amended our existing loan arrangement to
increase the maximum available amount of our revolving line of credit to
$3.0 million, extend the maturity date to December 1, 2000 and decrease the
interest rate to prime plus .50%. In conjunction with the loan amendment, we
entered into an agreement that provides for a separate $500,000 line of credit
facility. Borrowings are subject to a borrowing base of 90% of eligible foreign
accounts receivable and interest on this line is payable monthly at a rate of
prime plus .50%.

    Net cash used in operating activities was $13.0 million, $10.3 million and
$3.0 million for the years ended December 31, 1999, 1998 and 1997, respectively.
The cash used in operating activities was attributable primarily to net losses
of $15.1 million, $11.6 million and $3.8 million for the years ended
December 31, 1999, 1998 and 1997, respectively.

    Net cash used in investing activities was $1.7 million, $1.2 million and
$872,000 for the years ended December 31, 1999, 1998 and 1997, respectively. The
cash used in investing activities related primarily to purchases of computers,
software and equipment for internal use and, in 1999, furniture and leasehold
improvements for our new Philadelphia facility.

                                       20
<PAGE>
    Net cash provided by financing activities amounted to $78.3 million,
$11.7 million and $5.1 million for the years ended December 31, 1999, 1998 and
1997, respectively. 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 borrowing under 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 and $919,000 was provided from borrowings under an
available equipment line. In May 1999, we sold 9,191,176 shares of Series C
preferred stock for net proceeds of $23.1 million, $1.35 million of which was
comprised of the conversion of indebtedness under bridge financing incurred
earlier in 1999. In September 1999, we completed our initial public offering of
4,000,000 shares of common stock for net proceeds of $54.8 million.
Additionally, during 1999 we received proceeds of $1.9 million from the exercise
of common stock options and made net repayments of $838,000 on our line of
credit and long-term debt and $598,000 to related parties.

    On October 29, 1999, we entered into a seven and one-half year lease with a
realty company for our new operating facility in Philadelphia, Pennsylvania.
This lease is secured by a $600,000 letter of credit. We relocated several of
our departments to this facility during January 2000 and estimate that capital
expenditures, including leasehold improvements, furniture and equipment, of
approximately $1.2 million will be required related to this facility.

    During November 1999, we entered into a master operating lease agreement
with an equipment leasing company that provides for an equipment lease line of
up to $1,000,000. Assets under operating leases on the lease line will be
secured with a letter of credit equal to 60% of the outstanding balance. As of
December 31, 1999 approximately $523,000 was available under the equipment lease
line. Letters of credit totaling approximately $286,000 were outstanding to
secure the outstanding assets on the lease line.

    During December 1999, we entered into a five year lease commencing on
January 15, 2000 with a realty company for facilities in Redwood Shores,
California. We intend to begin occupying this facility in March 2000 and to use
this facility to house our West Coast operations.

    We anticipate that we will continue to expand our sales operations
throughout the U.S., as well as internationally, within the next 12 months and,
therefore, we expect to incur increases in our sales and marketing expenditures.
We also expect to incur increases in our product development expenditures as we
continue to enhance our product offerings. These expenditures are expected to
use significant amounts of our cash resources. However, we believe that our
existing capital resources are sufficient to meet our capital requirements for
the next 12 months. In addition, we may pursue acquisitions in the future. Such
acquisitions could require significant capital resources. Presently, we have no
definitive agreements, commitments or understandings to consummate any
acquisitions.

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. We

                                       21
<PAGE>
believe that most of our customers using an older version of one of our products
that is not Year 2000 compliant upgraded such version to a newer, compatible
version or discontinued using the software prior to January 1, 2000. We have not
been advised of any material Year 2000 problems by our customers to date.

    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 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 was completed during the third quarter of 1999 to ensure
that systems then not compliant or systems that were newly discovered to be
non-compliant were remedied. No information technology projects have been
delayed or deferred by our Year 2000 compliance program and we have not
experienced any material internal Year 2000 problems to date.

    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. 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. To date, there has been no material negative impact on
our financial condition or operations as a result of our Year 2000 compliance
program. 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 may arise 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. Although
none have been experienced to date, 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, if any, will have a material adverse impact on our
systems or results of operations.

    The costs of our Year 2000 identification, assessment, remediation and
testing efforts are based upon management's best estimates. 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.

                                       22

    Year 2000 issues may affect the purchasing patterns of current and potential
customers in a variety of ways. Some companies may be 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

FACTORS THAT MAY AFFECT FUTURE RESULTS AND MARKET PRICE OF STOCK

    THIS SECTION HIGHLIGHTS SPECIFIC RISKS WITH RESPECT TO AN INVESTMENT IN OUR
BUSINESS. INVESTING IN OUR COMMON STOCK INVOLVES A HIGH DEGREE OF RISK. WE ALSO
CAUTION YOU THAT THIS REPORT INCLUDES FORWARD-LOOKING STATEMENTS THAT ARE BASED
ON MANAGEMENT'S BELIEFS AND ASSUMPTIONS AND ON INFORMATION CURRENTLY AVAILABLE
TO MANAGEMENT.

    WE HAVE HAD RECENT LOSSES AND MAY INCUR FUTURE LOSSES THAT MAY DEPRESS OUR
    STOCK PRICE.

    We have incurred significant net losses since 1996, including losses of
approximately $3.8 million, $11.6 million and $15.1 million for the years ended
December 31, 1997, 1998, and 1999, respectively. Our losses have resulted in an
accumulated deficit of approximately $34.9 million as of December 31, 1999. We
expect to increase our research and development, sales and marketing and general
and administrative expenses in future periods. 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 INTERNET USAGE OR THE LACK OF ACCEPTANCE OF
    COMMERCE CONDUCTED VIA THE INTERNET COULD BE DETRIMENTAL TO OUR FUTURE
    OPERATING RESULTS.

    Our products enhance companies' ability to transact business and conduct
operations utilizing the Internet. Therefore, our future sales and any future
profits are substantially dependent upon the widespread acceptance and use of
the Internet as an effective medium of commerce by 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.

                                       23
<PAGE>
    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.

    WE DEPEND ON OUR SAPPHIRE/WEB PRODUCTS AND IF THE MARKET FOR THESE PRODUCTS
    DOES NOT CONTINUE TO GROW, OUR BUSINESS COULD BE MATERIALLY ADVERSELY
    AFFECTED.

    Software license revenues from our Sapphire/Web software were $3.4 million
or 42% of total revenues in 1998 and $11.7 million or 74% of total revenues of
1999. We expect to continue to be dependent upon the Sapphire/Web software
products in the future, and any 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. We expect to continue to commit significant resources to market and
further develop the Sapphire/Web software products and enhance the brand
awareness of Sapphire/Web and our other software products. The market for our
software may not continue to grow or may grow at a slower rate than we expect.
Furthermore, the market may not accept our products. If this market fails to
grow or grows more slowly than we anticipate, or if the market fails to accept
our products, our business could suffer.

    IF THE MARKET'S ACCEPTANCE AND ADOPTION OF JAVA AND XML-SERVER TECHNOLOGIES
    DOES NOT CONTINUE, OUR FUTURE RESULTS MAY SUFFER.

    Our Sapphire/Web product is 100% Pure JAVA. JAVA is a programming language
developed by Sun Microsystems. Therefore, the continued acceptance of our
products in the marketplace depends on JAVA's acceptance as a standard
programming language. If Sun Microsystems were to make significant changes to
the JAVA language or fail to 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.

                                       24
<PAGE>
    INTENSE COMPETITION AND INCREASING CONSOLIDATION IN OUR INDUSTRY COULD
    CREATE STRONGER COMPETITORS AND HARM OUR BUSINESS.

    The market for our products is intensely competitive, highly fragmented,
characterized by rapid technological change and significantly affected by new
product introductions. Recent acquisitions of several of our competitors by
large software companies and other market activities of industry participants
have increased the 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
competitors have longer operating histories, significantly greater financial,
technical, marketing and other resources, greater name recognition, a broader
range of products to offer and a larger installed base of customers than us, any
of which could provide them with a significant competitive advantage.

    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
also may face increased competition from existing large business application
software vendors that may broaden their product offerings to include Web
application server software. Their significant installed customer bases and
abilities to offer a broad solution and to price these new products as
incremental add-ons to existing systems could provide them with a significant
competitive advantage.

    OUR CUSTOMERS ARE CONCENTRATED AND THE LOSS OF ONE OF OUR LARGEST CUSTOMERS
    COULD CAUSE OUR REVENUES TO DROP QUICKLY AND UNEXPECTEDLY.

    Our top ten customers for the years ended December 31, 1998 and 1999 in the
aggregate accounted for approximately 39% and 56%, respectively, of our
revenues. Hewlett-Packard accounted for more than 10% of our revenues for the
year ended December 31, 1998 and OpenConnect accounted for more than 10% of our
revenues for the year ended December 31, 1999. We expect that a small number of
customers will continue to account for a substantial portion of revenues in any
given quarter in the foreseeable future, although it is unusual for the same
customer to account for a substantial amount of revenues in each of several
quarters. As a result, our inability to secure major customers during a given
period or the loss of any one major customer could cause our revenues to drop
quickly and unexpectedly.

    IF WE FAIL TO DEVELOP NEW PRODUCTS AND SERVICES IN THE FACE OF OUR
    INDUSTRY'S RAPIDLY EVOLVING TECHNOLOGY, OUR FUTURE RESULTS MAY BE ADVERSELY
    AFFECTED.

    Due to the recent emergence of the Internet and the Web as a forum for
conducting business, the market for Web application server systems in which we
participate is subject to rapid technological change, changing customer needs,
frequent new product introductions and evolving industry standards that may
render existing products and services obsolete. Our growth and future operating
results will depend in part upon our ability to enhance existing applications
and develop and introduce new applications or components that:

    - meet or exceed technological advances in the marketplace;

    - meet changing customer requirements;

    - achieve market acceptance;

    - integrate successfully with third party software; and

    - respond to competitive products.

                                       25
<PAGE>
    Our product development and testing efforts have required, and are expected
to continue to require, substantial investment. We may not possess sufficient
resources to continue to make the necessary investments in technology. In
addition, we may not successfully identify new software opportunities and
develop and bring new software to market in a timely and efficient manner. If we
are unable, for technological or other reasons, to develop and introduce new and
enhanced software in a timely manner, we may lose existing customers and fail to
attract new customers, resulting in a decline in revenues.

    OUR STOCK PRICE MAY FLUCTUATE WIDELY.

    Prior to our initial public offering in September 1999, there was no public
market for our common stock. Since then, the market price of our common stock
has fluctuated significantly. The market price of our common stock could
continue to fluctuate substantially due to:

    - quarterly fluctuations in operating results;

    - announcements of new products or product enhancements by us or our
      competitors;

    - technological innovations by us or our competitors;

    - general market conditions or market conditions specific to our or our
      customers' industries; and

    - changes in earnings estimates or recommendations by analysts.

    Stock prices of Internet-related companies have been highly volatile. Our
current stock price may not be indicative of the price of our stock that will
prevail in the trading market. In the past, following periods of volatility in
the market price of a company's securities, securities class action litigation
has at times been instituted against that company. If we become subject to
securities litigation, we could incur substantial costs and experience a
diversion of management's attention and resources.

    THE UNPREDICTABILITY OF OUR QUARTERLY OPERATING RESULTS MAY ADVERSELY AFFECT
    THE TRADING PRICE OF OUR COMMON STOCK.

    Quarterly fluctuations in operating results may be caused by:

    - changes in the growth rate of Internet usage;

    - fluctuations in the demand for our products and services;

    - the level of product and price competition in our markets;

    - the timing and market acceptance of new product introductions and upgrades
      by us or our competitors;

    - our success in expanding our customer support and marketing and sales
      organizations;

    - the size and timing of individual transactions;

    - delays in, or cancellations of, customer implementations;

    - customers' budget constraints;

    - the level of product development expenditures;

    - our ability to control costs; and

    - general economic conditions.

    Many of these factors are not in our control. In addition, we also
experience seasonality which causes us to typically recognize a
disproportionately greater amount of our revenues for any fiscal year

                                       26
<PAGE>
in our fourth quarter and a disproportionately lesser amount in our first
quarter, due largely to sales force quota practices in the software industry and
to customer budgeting processes.

    OUR FAILURE TO SUCCESSFULLY INTEGRATE FUTURE ACQUISITIONS COULD ADVERSELY
    AFFECT OUR BUSINESS.

    We intend to acquire complementary product lines, technologies and
businesses as part of our growth strategy. Although we may make such
acquisitions, we may not be able to successfully integrate them with our
business in a timely manner. Our failure to successfully address the risks
associated with such acquisitions, if consummated, could have a material adverse
effect on our business and our ability to develop and market products. The
success of any acquisitions will depend on our ability to:

    - successfully integrate and manage the acquired operations;

    - retain the key employees of the acquisition targets;

    - develop, integrate and market products and product enhancements based on
      the acquired products and technologies; and

    - control costs and expenses, as well as demands on our management,
      associated with the potential acquisitions.

    If we are not able to successfully integrate acquired product lines,
technologies or businesses with our business, we may incur substantial costs and
delays or other operational, technical or financial problems. In addition, our
failure to successfully integrate acquisitions may divert management's attention
from our existing business and may damage our relationships with key clients and
employees. To finance future acquisitions, we may issue equity securities that
could be dilutive to our stockholders. We may also incur debt and additional
amortization expenses related to goodwill and other intangible assets as a
result of future acquisitions. The interest expense related to this debt and
additional amortization expense may significantly reduce our profitability and
could have a material adverse effect on our business, financial condition and
operating results.

    WE NEED TO MANAGE OUR GROWTH EFFECTIVELY OR WE MAY NOT SUCCEED.

    We are a growing company. Our ability to manage our growth will depend in
large part on our ability to generally improve and expand our operational and
sales and marketing capabilities, to develop the management skills of our
managers and supervisors, many of whom have been employed by us for a relatively
short time, and to train, motivate and manage both our existing employees and
the additional employees that may be required. Additionally, we may not
adequately anticipate all of the demands that growth may impose on our systems,
procedures and structure. Any failure to adequately anticipate and respond to
these demands or manage our growth effectively would have a material adverse
effect on our future prospects.

    THE DEVELOPMENT OF INTERNATIONAL OPERATIONS WILL CAUSE US TO FACE ADDITIONAL
    RISKS.

    We expect to expand our international operations and international sales and
marketing efforts, initially, by opening regional sales and support offices in
Europe and Asia Pacific within the next eight months. We have limited experience
in marketing, selling and distributing our products and services
internationally. International operations, including operations in those regions
that we are targeting, are subject to the following risks:

    - recessions in foreign economies;

    - political and economic instability;

    - fluctuations in currency exchange rates;

    - difficulties and costs of staffing and managing foreign operations;

                                       27
<PAGE>
    - potentially adverse tax consequences;

    - reduced protection for intellectual property rights in some countries; and

    - changes in regulatory requirements.

    OUR FAILURE TO MAINTAIN ONGOING SALES THROUGH A LIMITED NUMBER OF INDIRECT
    CHANNELS MAY RESULT IN LOWER REVENUES.

    In 1999, we derived approximately 60% of our license revenues through a
limited number of independent software vendors, systems integrators,
distributors and resellers. Although we intend to increase our marketing and
direct sales efforts, we expect that a limited number of these indirect channels
will continue to account for a significant portion of our revenues in any given
quarter in the foreseeable future. To be successful, we must continue to foster
and maintain our existing indirect channels, as well as develop new
relationships. The loss of, or reduction in orders through, existing indirect
channels or the failure to develop new indirect channel relationships could
cause our revenues to decline and have a material adverse effect on our
business.

    IF WE LOSE OUR KEY PERSONNEL, OR FAIL TO ATTRACT AND RETAIN ADDITIONAL
    PERSONNEL, THE SUCCESS AND GROWTH OF OUR BUSINESS MAY SUFFER.

    A significant portion of our senior management team has been in place for a
relatively short period of time. Our success will depend to a significant extent
on their ability to gain the trust and confidence of our other employees and to
work effectively as a team.

    Our future success will also depend significantly on our ability to attract,
integrate, motivate and retain additional highly skilled technical, managerial,
sales, marketing, and services personnel. Competition for skilled personnel is
intense, and we may not be successful in attracting, motivating and retaining
the personnel required to grow and operate profitably. Failure to attract,
integrate, motivate and retain highly skilled personnel could adversely affect
our business, especially our ability to develop new products and enhance
existing products.

    THE LENGTHY AND VARIABLE SALES CYCLES OF OUR SOFTWARE PRODUCTS COULD CAUSE
    SIGNIFICANT FLUCTUATION IN OUR QUARTERLY RESULTS.

    Our software products are generally used for mission-critical or
enterprise-wide purposes and involves a significant commitment of resources by
our customers. A customer's decision to license our software products generally
involves the evaluation of the available alternatives by a significant number of
personnel in various functional and geographic areas, each often having specific
and conflicting requirements. Accordingly, we typically must expend substantial
resources educating prospective customers about the value of our software
solutions. For these reasons, the length of time between the date of initial
contact with the potential customer and the execution of a software license
agreement typically ranges from three to six months, and is subject to delays
over which we have little or no control. As a result, our ability to forecast
the timing and amount of specific sales is limited and the delay or failure to
complete one or more large license transactions could cause our operating
results to vary significantly from quarter to quarter.

    THE FAILURE TO IMPLEMENT SUCCESSFULLY OUR SOFTWARE PRODUCTS COULD RESULT IN
    DISSATISFIED CUSTOMERS AND DECREASED SALES.

    Implementation of our software products often involves a significant
commitment of financial and other resources by our customers. The customer's
implementation cycle can be lengthy due to the size and complexity of their
systems and operations. In addition, our customers rely heavily on third party
systems integrators to assist them with the installation of the software. Our
failure or the failure of our

                                       28
<PAGE>
alliance partners, our customers or our third party integrators to implement
successfully our software products could result in dissatisfied customers which
could limit our ability to generate repeat business and adversely affect our
reputation.

    WE MAY REQUIRE FUTURE ADDITIONAL FUNDING FOR OUR BUSINESS.

    Over time, we may require additional financing for our operations.
Additionally, we periodically review other companies and their product lines and
technologies for potential acquisition. Any material acquisitions or joint
ventures could require additional financing. This additional financing may not
be available to us on a timely basis, if at all, or, if available, on terms
acceptable to us. Moreover, additional financing may cause dilution to existing
stockholders.

    CAPACITY RESTRICTIONS COULD REDUCE THE DEMAND AND UTILITY OF OUR PRODUCTS.

    Concurrency restrictions can limit Internet deployment and use capacity. The
boundaries of our Sapphire/Web software and Bluestone XML-Server capacity, in
terms of numbers of concurrent users or interactions, are unknown because, to
date, no customer or testing environment has reached these boundaries. The
Sapphire/Web software's or the Bluestone XML-Server's capacity boundaries may,
at some future time, be reached and, when reached, may be insufficient to enable
our customers to achieve their desired levels of information deployment and
exchange. We may lose customers or fail to gain new customers if either of the
Sapphire/Web software's or the Bluestone XML-Server's capacity boundary limits
the ability of our customers to achieve expected levels of information
deployment and exchange or Internet commerce transactions.

    OUR LIMITED ABILITY TO PROTECT OUR INTELLECTUAL PROPERTY RIGHTS COULD IMPAIR
    OUR ABILITY TO COMPETE EFFECTIVELY.

    Our success and ability to compete are substantially dependent on our
internally developed technologies and trademarks, which we protect through a
combination of copyright, trademark and trade secret laws, confidentiality
procedures and contractual provisions.

    Despite our efforts to protect our proprietary rights, unauthorized parties
may attempt to copy aspects of our products or obtain and use information that
we regard as proprietary. Policing unauthorized use of our products is difficult
and, though we are unable to determine the extent to which piracy of our
software products exists, we expect software piracy to be a problem. In
addition, the laws of some foreign countries do not protect our proprietary
rights to the same extent as the laws of the United States. Furthermore, our
competitors may independently develop technology similar to ours.

    The number of intellectual property claims in our industry may increase as
the number of competing products grows and the functionality of products in
different industry segments overlaps. Although we are not aware that any of our
products infringe upon the proprietary rights of third parties, there can be no
assurance that third parties will not claim infringement by us with respect to
current or future products. Any of these claims, with or without merit, could be
time consuming to address, result in costly litigation, cause product shipment
delays or require us to enter into royalty or license agreements. These royalty
or license agreements might not be available on terms acceptable to us or at
all, which could have a material adverse effect on our business.

    OUR FAILURE TO OBTAIN OR MAINTAIN THIRD PARTY LICENSES COULD HARM OUR
    BUSINESS.

    We have in the past and may in the future, resell, under license, certain
third party software that enables our software to interact with other software
systems or databases. In addition, we license certain software technology used
to develop our software. The loss or inability to maintain any of these

                                       29
<PAGE>
software licenses could result in delays or reductions in product shipments
until equivalent software could be identified and licensed or compiled, which
could adversely affect our business.

    WE MAY BE SUBJECT TO FUTURE PRODUCT LIABILITY CLAIMS AND OUR PRODUCTS'
    REPUTATIONS MAY SUFFER.

    Many of our installations involve projects that are critical to the
operations of our customers' businesses and provide benefits that may be
difficult to quantify. Any failure in a customer's system could result in a
claim for substantial damages against us, regardless of our responsibility for
the failure. Although our license agreements with our customers typically
contain provisions designed to limit contractually our liability for damages
arising from negligent acts, errors, mistakes or omissions, it is possible that
these provisions will not be enforceable in certain instances or would otherwise
not protect us from liability for damages. Although we maintain general
liability insurance coverage, this coverage may not continue to be available on
reasonable terms or at all, or may be insufficient to cover one or more large
claims.

    We have entered into and plan to continue to enter into agreements with
strategic alliance partners whereby we license our software products for
integration with the alliance partners' software. If an alliance partner's
software fails to meet customer expectations or causes a failure in its
customer's systems, the reputation of our software products could be materially
and adversely affected even if our software products performed in accordance
with their functional specifications.

    YEAR 2000 PROBLEMS MAY DISRUPT OUR BUSINESS.

    We have not experienced any material internal Year 2000 problems to date.
While our software products are not time/date sensitive, many of the third party
software applications run by our customers are time/date sensitive. We have not
been advised of any material Year 2000 problems by our customers to date. We
have, however, in the past resold third party software that may not be Year 2000
compliant. While we have not been made aware of any material Year 2000 problems
relating to the hardware and software used by our customers in connection with
our products to date, these problems may exist. Should any of these problems
develop, they may have a material adverse effect on our business, operating
results and financial condition. In addition, we utilize software, computer
technology and other services internally developed and provided by third party
vendors that may have Year 2000 issues. Although we have not experienced any of
these problems to date, the failure of our internal computing systems or of
systems provided by third party vendors to be Year 2000 compliant could
materially adversely affect our business.

    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 may still be 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. Many companies may continue to wait some length of time to assure
that their systems are Year 2000 compliant prior to making commitments to
purchase our products.

    If our potential customers delay purchasing or implementing our products in
order to address the Year 2000 issue, our business would be seriously harmed.

    Our costs related to Year 2000 compliance, which thus far have not been
material, could ultimately be significant if Year 2000 problems surface. In the
event that we experience disruptions as a result of any Year 2000 problems, our
business could be seriously harmed.

    Our insurance coverage may not cover or be adequate to offset these and
other business risks related to the Year 2000.

                                       30
<PAGE>
    OUR EXECUTIVE OFFICERS AND DIRECTORS AND THEIR AFFILIATES OWN A LARGE
    PERCENTAGE OF OUR VOTING STOCK AND HAVE THE ABILITY TO INFLUENCE DECISIONS
    THAT COULD ADVERSELY AFFECT OUR STOCK PRICE.

    Our executive officers, directors and their affiliates own a large
percentage of the outstanding shares of common stock. As a result, these
stockholders are able to substantially influence all matters requiring
stockholder approval and, thereby, our management and affairs. Matters that
require stockholder approval include:

    - election of directors;

    - certain mergers or consolidations; and

    - sale of all or substantially all of our assets.

    This concentration of ownership may delay, deter or prevent acts that would
result in a change of control of Bluestone, which in turn could reduce the
market price of our common stock.

    OUR CHARTER AND BYLAWS AND DELAWARE LAW CONTAIN PROVISIONS THAT COULD
    DISCOURAGE A TAKEOVER EVEN IF BENEFICIAL TO STOCKHOLDERS.

    Our charter and our bylaws, in conjunction with Delaware law, contain
provisions that could make it more difficult for a third party to obtain control
of Bluestone even if doing so would be beneficial to stockholders. For example,
our charter provides for a classified board of directors and allows the board of
directors to expand its size and fill any vacancies without stockholder
approval. In addition, our bylaws restrict the ability of stockholders to call a
special meeting.

    FUTURE SALES OF OUR COMMON STOCK MAY DEPRESS OUR STOCK PRICE.

    The market price of our common stock could decline as a result of sales by
our existing stockholders or the perception that those sales may occur. These
sales also could 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.
The holders of a significant amount of our common stock, as well as the holders
of outstanding warrants are 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.

ITEM 7A. 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 interest income is sensitive to changes in the general level of U.S.
interest rates. However, we 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.

                    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, 1998 and 1999, 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, 1999. 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, 1998 and 1999 and the results of its operations and its cash
flows for each of the three years in the period ended December 31, 1999, in
conformity with generally accepted accounting principles.

                         NOTES TO FINANCIAL STATEMENTS

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 World Wide Web in a
controlled manner, supporting high volumes of users and interactions. On
April 17, 1997, in connection with the sale of Series A Convertible Preferred
Stock (see Note 6), 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 was named Bluestone
Consulting, Inc. ("BCI") and in 1997 provided the Company with certain
administrative services under a shared services agreement (see Note 12). The
consulting division spin-off is reported in the accompanying financial
statements as a discontinued operation (see Note 2).

    The Company has incurred significant losses, and as of December 31, 1999 had
an accumulated deficit of $34.9 million. For the years ended December 31, 1997,
1998 and 1999 the Company's net losses were $3.9 million, $11.6 million and
$15.1 million, respectively. The Company intends to invest heavily in product
development, sales and marketing and the development of its administration
organization. There can be no assurance that the Company will be able to
generate sufficient revenues to achieve or sustain profitability in the future.
However, the Company believes that its current cash and cash equivalents will be
sufficient to sustain its operations through December 31, 2000.

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES:

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.

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.

OTHER ACCRUED EXPENSES

    Other accrued expenses at December 31, 1999 includes $505,733 for accrued
bonuses and $628,307 for accrued payroll taxes.

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 primarily sells perpetual licenses to end-users and perpetual,
annual and multi-year licenses 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 or
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. Revenues 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 13% of net revenues for the year ended December 31,
1999 and two customers accounted for approximately 12% and 14%, respectively, of
net accounts receivable at December 31, 1999. No one customer accounted for
greater than 10% of net revenues for the year ended December 31, 1997 or greater
than 10% of net accounts receivable at December 31, 1997.

ADVERTISING COSTS

    The Company expenses advertising costs as incurred. Advertising expense for
continuing operations for the years ended December 31, 1997, 1998 and 1999 was
$615,374, $882,761 and $2,022,252, respectively, including $251,640, $549,487
and $1,040,189, 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

                   NOTES TO FINANCIAL STATEMENTS (CONTINUED)

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES: (CONTINUED)

income or losses were included in the sole stockholder's tax return. In
connection with the Series A Convertible Preferred Stock sale (see Note 6), 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 and director stock options. Under
APB No. 25, if the exercise price of the Company's 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 10).

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, 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.

RECAPITALIZATION

    In August 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
Company's Initial Public Offering (see below). The reverse stock split has been
retroactively reflected in the accompanying financial statements.

INITIAL PUBLIC OFFERING

    On September 29, 1999 the Company consummated an initial public offering of
its Common Stock (the "Initial Public Offering"). The Company sold
4,000,000 shares of its Common stock at an initial

public offering price of $15.00 per share. After deducting the underwriters'
discount and other offering expenses, the net proceeds to the Company were
approximately $54.8 million.

DISCONTINUED OPERATIONS

    On April 17, 1997, in connection with the sale of Series A Convertible
Preferred Stock (see Note 6), 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 $4,537,147 for the year ended
December 31, 1997. The spin-off was treated as a tax-free reorganization for
federal and state income tax purposes.

RECENT ACCOUNTING PRONOUNCEMENTS

    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.

RECLASSIFICATIONS

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

3. 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 4). 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 4). The line is cross-defaulted and cross-collateralized with the equipment
line. The loan agreement also requires the Company to maintain certain financial
and nonfinancial covenants, as defined.

                   NOTES TO FINANCIAL STATEMENTS (CONTINUED)

3. LINE OF CREDIT: (CONTINUED)

    During December 1999, the Company amended the loan arrangement to increase
the maximum available amount of the revolving line of credit to $3.0 million,
extend the maturity date to December 1, 2000 and decrease the interest rate to
prime plus .50%. At December 31, 1999, borrowings of approximately $1,572,000
were available under the line. Letters of credit of approximately $886,000,
related to certain operating leases (see Note 13), were outstanding at
December 31, 1999 and therefore have been deducted from available borrowings
under the line. In conjunction with the December 1999 loan amendment, the
Company entered into an agreement that provides for a separate $500,000 line of
credit facility. Borrowings are subject to a borrowing base of 90% of eligible
foreign accounts receivable.

    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. In October 1999, the Company issued 9,100 shares of
common stock to the bank in exchange for the warrant.

    At December 31, 1997, the Company's equipment line provided for borrowings
of up to $500,000 for approved capital expenditures, as defined and interest
payable monthly on the outstanding balance at a rate of prime plus 1.5%. In
June 1998, the outstanding borrowings as of that date of $237,620 converted to a
term note payable in 36 monthly installments. On August 16, 1998, the Company
and the bank modified the equipment line to provide for additional borrowings of
up to $1,762,380 for approved capital expenditures, as defined. Interest is
payable monthly on the outstanding balance at a rate of prime plus 1.25%. On
March 31, 1999, the then outstanding balance of $959,086 was converted to a term
note payable in 36 monthly installments and no additional borrowings are
available under the equipment line. The term note under the equipment line is
secured by equipment and is cross-defaulted and cross-collateralized with the
Company's line of credit (see Note 3).

    At December 31, 1998 and 1999, property under capital leases totaled
$130,897 with corresponding accumulated amortization of $90,900 and $117,565,
respectively.

5. SUBORDINATED NOTES DUE TO RELATED PARTIES:

    In January 1996, the Company entered into a $1,000,000, subordinated 10%
loan agreement with the brother of the Company's founder. The agreement, as
amended in connection with the BCI spin-off, provided for BCI to assume $500,000
of the convertible note with the Company assuming the remaining $500,000 of the
convertible note. To achieve an equal distribution of debt between BCI and

premium.

6. MANDATORILY REDEEMABLE SERIES A CONVERTIBLE PREFERRED STOCK:

    On April 18, 1997, the Company sold 5,526,316 shares of $0.001 par value
Series A Convertible Preferred stock to certain venture capital investors, an
individual investor and the Company's former sole shareholder for $5,250,000.
This included 263,158 shares sold to the former sole stockholder in exchange for
canceling a $250,000 note payable due him. The Series A Preferred stock was
convertible into 0.3125 shares of Common stock, subject to adjustment, as
defined, and was automatically convertible upon a public stock offering, as
defined.

    Dividends on the Series A Preferred were cumulative at $0.057 per share per

share. At December 31, 1997 and 1998 cumulative dividends accrued but not
declared were $222,658 and $537,658, respectively. Beginning in April 2003, the
holders would have been able to require the Company to redeem the Series A
Preferred at $0.95 per share plus accrued dividends over a three-year period.
The Series A Preferred stockholders would have been able to participate in
Common stock dividends and had Common stock voting rights on an as converted
basis. Upon completion of the Company's initial public offering in September
1999, all of the outstanding shares of Series A Preferred stock and the accrued
dividends thereon were converted into Common stock.

7. MANDATORILY REDEEMABLE SERIES B CONVERTIBLE PREFERRED STOCK:

    On April 23, 1998, the Company sold 8,782,695 shares of Series B Convertible
Preferred stock to certain venture capital investors, including its original
investors (see Note 6) for approximately $11.4 million in cash. The Series B
Preferred was senior to the Series A Preferred and was originally convertible
into 0.3125 shares of Common stock. In 1998, in accordance with the original
terms of the Series B Preferred stock purchase agreement, the conversion ratio
was adjusted so that each share of Series B Preferred was convertible into
0.6541 shares of Common stock. In addition, the Series B Preferred was
automatically convertible upon a public stock offering, as defined.

    Dividends on the Series B Preferred were cumulative at $0.078 per share per
annum and the Series B Preferred had a liquidation preference of $1.296 per
share. At December 31, 1998, cumulative dividends accrued but not declared were

would have been able to participate in Common stock dividends and had Common
stock voting rights on an as converted basis. Upon completion of our initial
public offering in September 1999, all of the outstanding shares of Series B
Preferred Stock and the accrued dividends thereon were converted into Common
stock.

8. MANDATORILY REDEEMABLE SERIES C CONVERTIBLE PREFERRED STOCK:

    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 was
senior to the Series A Preferred and Series B Preferred and was automatically
convertible into Common stock upon a public stock offering, as defined.
Dividends on the Series C Preferred were cumulative at $0.1632 per share per
annum. The Series C Preferred stockholders would have been able to participate
in Common stock dividends and had Common stock voting rights on an as converted
basis. 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. Upon completion of our initial public offering in
September 1999, all of the outstanding shares of Series C Preferred stock and
the accrued dividends thereon were converted into Common stock.

9. CONVERTIBLE SUBORDINATED NOTES AND WARRANTS:

    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 1999. The notes were converted into 496,322 shares
of Series C Preferred stock on May 25, 1999. During December 1999, 84,859 shares
of Common stock were issued to certain investors pursuant to their warrant
exercises. At December 31, 1999, 50,644 warrants remain outstanding related to
this Note and Warrant Purchase Agreement.

10. STOCK OPTION AND EMPLOYEE BENEFIT PLANS:

STOCK OPTION PLANS

    In 1996, the Company adopted the 1996 Incentive and Non-Qualified Stock
Option Plan (the "1996 Plan") under which incentive and nonstatutory stock
options to acquire shares of the Company's Common stock may be granted to
officers, employees and consultants of the Company. Incentive stock options must
be issued at an exercise price not less than the fair market value of the
underlying shares on the date of grant. Options granted under the 1996 Plan are
exercisable over a period of time, not to exceed ten years, and are subject to
other terms and conditions specified in the individual option grants. In
April 1997, in connection with the sale of Series A Convertible Preferred stock
(see Note 6),

June 1999, the 1996 Plan was amended to increase the total shares available
under the plan to 2,946,578 and in August 1999, the 1996 Plan was amended to
increase the total shares available under the plan to 3,290,328. In January

</TABLE>

    The options under the 1996 Plan generally vest over a four-year period. At
December 31, 1999 there were options to purchase 824,615 shares of Common stock
exercisable and options to purchase 224,042 shares of Common stock were
available for future grant under the 1996 Plan prior to the January 2000
amendment. The weighted average remaining contractual life of the outstanding
options at December 31, 1999 was 9.01 years.

    In connection with certain options granted to employees during 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 year ended December 31, 1999, $281,998 of deferred
compensation was charged to expense. At December 31, 1999, the Company had
$1,133,550 of deferred compensation to be amortized over the remaining vesting
periods.

    Included in options granted below fair market value during the year ended
December 31, 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 1999 related to these options.

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

    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 quarterly and annual performance
goals. The Company granted 244,694 options under the bonus pool for the
Company's quarterly operating results during the year ended December 31, 1999.
On January 7, 2000, options to purchase 111,777 shares of Common stock were
granted related to the achievement of annual goals for the year ended
December 31, 1999. 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 reserved for
issuance under the Directors' Compensation Plan is 156,250. As of December 31,
1999, 10,936 options were granted at a weighted average exercise price of $23.13
per share to non-employee directors of the Company pursuant to the Directors'
Compensation Plan.

    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 plans. Had compensation cost for the plans 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,
1998 and 1999 would have increased to the following pro forma amount:

</TABLE>

    The weighted average fair value of the options granted is estimated as $8.38
per share on the date of grant using the Black-Scholes option-pricing model with
the following assumptions: no expected dividend yield, a volatility of 0% to
70%, a weighted average risk-free interest rate of 5.567% based on the rates in
effect on the date of grant, and an expected life of seven years.

RETIREMENT SAVINGS PLAN

    The Company has a retirement savings plan (the "Plan") that qualifies under
Section 401(k) of the Internal Revenue Code. Eligible employees may contribute
up to 15% of their annual compensation, as defined by the Plan. The Company
contributes to the Plan at a rate of 10% of the employee's contributions up to a
maximum of $1,000. The Company's contributions to the Plan were $22,009, $31,807
and $40,151 for the years ended December 31, 1997, 1998 and 1999, respectively.

    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, 1999, the Company had a
net operating loss carryforward of approximately $29 million beginning to expire
in 2012 for federal tax purposes and in 2004 for state tax purposes.

12. TRANSACTIONS WITH BCI:

    On April 17, 1997, in connection with the sale of the Series A Convertible
Preferred stock (see Note 6), 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, 1998 and 1999, the Company's sales to BCI totaled $40,448,
$58,607 and $951,667, respectively, and total purchases from BCI were $47,088,

includes $23,299 and $431,131, respectively, due from BCI and accounts payable
includes $77,097 and $0, respectively, payable to BCI. In December 1999 the
Company entered into a services agreement with BCI, whereby BCI will provide the
Company two consultants during 2000 for $700,000 in the aggregate, payable
quarterly during 2000.

    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 $150,000 in 1999, for the sub-contracted support services.

    The Company also sub-leases a portion of its operating facility to BCI (see
Note 13). Amounts charged to BCI, which reduced the Company's rent expense for
the years ended December 31, 1997, 1998 and 1999, totaled $130,588, $74,165 and
$93,510, respectively. During the years ended December 31, 1998 and 1999, the
Company rented certain equipment from BCI, totaling $89,489 and $89,530,
respectively.

    In connection with the Series A Convertible Preferred stock sale and
spin-off of BCI, the Company issued a $500,000, 10% note payable to BCI (see
Note 5). In November 1999, the Company repaid this note in full.

13. COMMITMENTS AND CONTINGENCIES:

    The Company has operating leases on its office facilities (see Note 12) and
certain equipment. Future minimum lease payments under such noncancelable
operating leases are summarized as follows, as of December 31, 1999:

</TABLE>

    On October 29, 1999, the Company entered into a seven and one-half year
lease for additional office facilities. The lease is secured by a $600,000
letter of credit (see Note 3). During November 1999, the Company entered into a
master operating lease agreement with an equipment leasing company that provides
for an equipment lease line of up to $1,000,000. Assets under operating leases
on the lease line will be secured with a letter of credit equal to 60% of the
asset amount. As of December 31, 1999, approximately $523,000 was available on
the equipment lease line. Letters of credit of approximately $286,000 (see
Note 3) were outstanding to secure the outstanding assets on the equipment lease
line.

    Rent expense for continuing operations was $551,832, $691,615 and $868,683
for the years ended December 31, 1997, 1998 and 1999, respectively.

    The Company is involved in certain legal actions arising in the ordinary
course of business. Management believes that the outcome of such actions will
not have a material adverse effect on the Company's financial position or
results of operations.

                  RECENT SALES OF UNREGISTERED SECURITIES

    During the past three years, Bluestone 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, Bluestone
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. Each share of Series A preferred
stock was converted into 0.3125 shares of common stock at Bluestone's initial
public offering.

    In connection with Bluestone's credit facility with Silicon Valley Bank,
Bluestone 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 was exercisable were 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 Bluestone 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 was exercisable were 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. In October 1999, Bluestone
issued 9,100 shares of common stock to Silicon Valley Bank upon the cashless
exercise of the warrant.

    Pursuant to a stock purchase agreement dated April 22, 1998, Bluestone
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 $2.72 per
share. No underwriters were used for such offering. Each share of Series B
preferred stock was converted into 0.6541 shares of common stock at Bluestone's
initial public offering.

    On January 21, 1999, Bluestone 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"). Bluestone 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 issuance of
9,191,178 shares of Series C preferred stock at $2.72 per share on May 25, 1999.
In December 1999, Bluestone issued 84,859 shares of common stock to entities
affiliated with Patricof & Co, Ventures, Inc. upon the cashless exercise of
their warrants.

    Pursuant to a stock purchase agreement dated May 25, 1999, Bluestone issued
9,191,178 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 $2.72 per share. Each share of Series C preferred stock was
converted into 0.3125 shares of common stock at Bluestone's initial public
offering.

    From March 1, 1996 to October 6, 1999, Bluestone granted stock options to
purchase 3,038,666 shares of common stock at exercise prices ranging from $2.24
to $23.13 per share to employees, consultants and directors pursuant to its
Amended and Restated 1996 Incentive and Non-Qualified Stock Option Plan.

<PAGE>

    Between March 1998 and October 6, 1999, 80,808 shares of common stock of
Bluestone have been issued to current and former employees pursuant to the
exercise of stock options.

    Bluestone believes that, prior to October 6, 1999, all grants of stock
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. Bluestone believes that all of the 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 Bluestone 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 Bluestone.
