Overview

Excalibur designs,  develops,  markets and supports  enterprise-wide,  accurate,
scalable and secure  knowledge-retrieval  and digital asset management  software
solutions.  Excalibur's comprehensive suite of products which includes Excalibur
RetrievalWare,   Excalibur  RetrievalWare  WebExpress,  Excalibur  RetrievalWare
FileRoom,   Excalibur   Internet   Spider,   Excalibur  EFS,   Excalibur  Visual
RetrievalWare,  Excalibur  Screening Room and Excalibur  Video Analysis  Engine,
enables individuals to quickly capture, analyze, index, catalog, browse, access,
search,  retrieve  and use  relevant  information  residing  on an  enterprise's
networks, intranets,  extranets and the Internet. Retrievable assets or document
data types include paper documents,  text, databases, word processing documents,
PDF (Portable Document Format) files,  newsfeeds,  groupware  systems,  e-mails,
images,  and video.  Excalibur's  software  solutions  deliver  capabilities for
real-time  profiling and retrospective  search,  combined full-text and database
searching,   word  meaning-based  semantic  searching,   fault-tolerant  pattern
recognition-based   searching,   statistical  searching  and  a  full  suite  of
traditional keyword and Boolean search techniques.  Excalibur RetrievalWare, the
Company's  flagship product,  has a modular  architecture that supports parallel
processing  on  distributed,  multi-threaded  servers and is designed to support
both very large databases and large information systems with thousands of users.
It offers users a web-based  unified view of all information  assets and enables
highly  accurate  search and retrieval over these assets.  Excalibur  offers its
software  solutions  to  information  systems for  workgroups,  enterprises  and
distributed  wide area networks,  including the Internet and World Wide Web. The
Company also offers training,  consulting and maintenance services to facilitate
implementation and use of Excalibur technology.

Excalibur's software products combine two unique and complementary technologies:
semantic  network  and  Adaptive  Pattern  Recognition   Processing  (APRP(TM)).
Semantic network leverages lexical knowledge at the highest level using built-in
knowledgebases  to search for specific word  meanings  enriched by related terms
and  concepts.  The APRP(TM)  technology  identifies  patterns in digital  data,
providing  the  capability to build  content-based  retrieval  applications  for
virtually any type of digital information.  By integrating these two approaches,
Excalibur believes that it delivers the most complete, powerful, yet easy to use
search and  retrieval  capabilities  available  today.  The combined  technology
powers most Excalibur applications.

                                       1

Text Products:

Excalibur's  text  retrieval  products  contributed  94%,  97%, and 96% of total
consolidated revenue in 1999, 1998 and 1997, respectively.

Excalibur RetrievalWare

Excalibur  RetrievalWare offers an advanced  componentized approach to knowledge
retrieval,  an enabling technology to knowledge  management.  A high-performance
scalable, more accurate alternative to traditional search and retrieval systems,
Excalibur  RetrievalWare  is a  comprehensive  software  solution  designed  for
enterprise  knowledge  retrieval  and intended to empower  users to find mission
critical  data across  multiple  data  types,  all  through a unified  view.  By
integrating   the  APRP(TM)  and  semantic   network   technologies,   Excalibur
RetrievalWare  delivers superior levels of power and performance  throughout the
entire  information  management  process,  from data  capture  and  indexing  to
searching,  retrieval  and  dissemination.  The latest  version of the  product,
Excalibur  RetrievalWare  6.6, was released in the second  quarter of the fiscal
year 1999. It extends access and retrieval from major  groupware  platforms such
as Microsoft  Exchange  and Lotus Notes.  Other  enhancements  include  extended
security  features,  the ability to  recognize  and  highlight  proper names and
entities and an enhanced user interface.  Overall,  Excalibur  RetrievalWare now
supports  more  than  200  document  formats  including  Microsoft  Office  '97.
Excalibur  RetrievalWare  provides  real time  profiling  which enables users to
create  and save Real Time  Agent  Queries  (Profiles)  that will  automatically
collect  incoming  documents of interest.  The  RetrievalWare  Profiling  Server
filters,  stores  and  distributes  incoming  data  from  any  source  including
real-time   newsfeeds,   relational   databases,   paper  repositories  and  the
RetrievalWare Internet Spider.

With Excalibur's semantic networks,  users can easily and automatically find the
required information in text databases by using all of the power and richness of
natural  language  processing.   Excalibur  RetrievalWare  incorporates  syntax,
morphology  and the actual  meaning of words.  The  baseline  semantic  network,
created from complete  dictionaries,  a thesaurus and other  reference  sources,
gives users a built-in knowledge base of 500,000 word meanings,  50,000 language

                                       3
<PAGE>

idioms and 1.6 million  word  associations.  Users enter  straightforward  plain
English  queries  that are  automatically  enhanced  by the  related  terms  and
concepts  thereby  increasing the  opportunity for the return of highly relevant
data. The software  recognizes words at the root level,  idioms and the multiple
meanings of words.  An important  benefit of this approach is the elimination of
the costs associated with defining keywords,  building topic trees, establishing
expert rules and sorting and labeling information in database fields.  Excalibur
RetrievalWare also enables the integration of specialized  semantic networks for
legal, medical, finance, engineering and other disciplines.

APRP(TM) identifies patterns in digital  information.  In text applications,  it
provides  fuzzy  searching  with a high degree of precision  and recall,  giving
end-users the ability to retrieve even  approximations  of search queries with a
high degree of confidence that all of the requested information will be returned
regardless  of errors in spelling or the existence of "dirty data." The software
works at high  speed  and  supports  the  rapid  development  of  multi-language
text-retrieval systems.

Excalibur  RetrievalWare  provides  access to both  unstructured  and structured
information  across  enterprise  networks,  workgroup  LANs, and intranets.  The
software  may be  deployed  on a single  server  or on any  number  of  physical
servers.  Excalibur  RetrievalWare  server  solutions  can be  run  on  multiple
platforms including leading UNIX and Windows NT platforms.

The Excalibur RetrievalWare product family includes the following components:

Excalibur RetrievalWare SDK

The Excalibur  RetrievalWare  SDK (Software  Developer's Kit) is a comprehensive
set of tools for building advanced content management solutions.  At its core is
a highly scalable,  distributed client/server  architecture.  Independent server
processes maximize the efficiency and reliability of document loading,  indexing
and query  handling  and support  security and  encryption/decryption  features.
Dedicated  server  processes  enable  integration  of text search and relational
database (DBMS) storage  capabilities  through an open DBMS gateway.  The client
environment  is optimized  for the  development  of graphical  interfaces  using
industry standard tools such as Java and Visual Basic.  Excalibur  RetrievalWare
delivers Visual Basic custom  controls,  remote  procedure calls and open server
capabilities as well as engine-level,  high-level and client/server  application
program interfaces (APIs).  These features speed the development of systems that
can support thousands of users and contain custom functionality.

Excalibur RetrievalWare FileRoom

Excalibur RetrievalWare FileRoom is built on Excalibur RetrievalWare  technology
and is an optional  component to allow loading,  indexing,  viewing and managing
scanned  documents,  images  and  text.  Users  access  the  FileRoom  through a
hierarchy consisting of fileroom documents,  where each tier in the hierarchy is
a container for storing documents.  Users can directly view the scanned image of
a retrieved document from the FileRoom. Graphs, diagrams,  handwritten notations
and signatures in the retrieved  document are  immediately  accessible.  "Fuzzy"
searching  capabilities  provided  by  APRP(TM)  give  users  a  high  level  of
confidence  that their  queries  will  return all of the  requested  information
regardless  of  the  quality  of  Optical  Character   Recognition  (OCR)  data.
Document-level  security lets organizations  control user access at the fileroom
(library), cabinet, drawer, folder and document level.

Excalibur RetrievalWare WebExpress

Excalibur  RetrievalWare  WebExpress is a search and retrieval tool designed for
online  service  providers  and  content-rich  Internet  portals.  RetrievalWare
WebExpress  offers  superior  search  accuracy,   performance  and  scalability,
supporting high numbers of concurrent  users  searching large and  heterogeneous
document collections.

Excalibur Internet Spider

Excalibur Internet Spider is a multimedia,  high-performance  web spider/crawler
for augmenting the knowledge retrieval capabilities of Excalibur  RetrievalWare,
for stand-alone use, or for integration with other applications.  In addition to
HTML-based web pages,  Excalibur Internet Spider also retrieves word processing,
PDF, and multimedia  assets  including audio,  video,  and images.  It is highly
configurable and multi-threaded and can crawl as deeply,  broadly,  and as often
as is necessary.  Users who want immediate  notification  when items of interest
arrive can post Agent  Profiles  to pull  links to  related  documents  to their
desktops.   Components  can  be  deployed  on  multiple   machines  for  optimum
performance and bandwidth.

Excalibur Electronic Filing Software (EFS)

Excalibur  EFS  version  3.7 is the  latest  version  of the  product  which was
originally  introduced in 1991 and is in the process of being phased out.  Users
of EFS are being migrated to RetrievalWare with the FileRoom option. EFS enables
text and images to be entered into the system from computer  files,  scanners or
facsimile  machines  (after the scanned  image is  converted  to text by optical
character  recognition  software) and are  automatically  filed and indexed in a
replica of a physical file room with file cabinets, drawers, folders, in-baskets
and wastebaskets,  utilizing a graphical user interface. EFS provides users with
multiple  methods  for  document  retrieval  and  operates  under  leading  UNIX
operating  systems and Windows NT in a  client/server  environment.  Client-only
implementations  are available on personal  computers  running Microsoft Windows
and Apple Macintoshes. EFS also provides links to leading external databases and
APIs  that  give  users  the  ability  to  integrate  EFS  with  other  software
applications  and  products.  A  variation  of this  software  product  provides
document image management capability for the World Wide Web.


Visual Products:

Excalibur's  visual  retrieval  products  contributed  6%,  3% and  4% of  total
consolidated revenue in 1999, 1998 and 1997, respectively.

Excalibur Visual RetrievalWare

Leveraging the APRP(TM)  technology,  Excalibur Visual RetrievalWare is a visual
retrieval engine and a comprehensive  image processing  library and programmer's
toolkit that enables the development of client/server systems that automatically
index and retrieve digital images.  Applications range from electronic  shopping
and digital libraries to document imaging and positive identification. Users can
search  for  visual  information  directly  from  their  intranet,  a  corporate
database,  the Internet,  or other sources using images or video clips as clues.
Visual data is reduced to a searchable  index that is typically less than 10% of


                                       5
<PAGE>

the size of the  original  image and is  automatically  recognized  based on its
shape, color and texture.  Users submit queries using examples of visual data or
by authoring a visual clue with a graphical  product.  Based on the shape, color
and texture of the visual clue, a list of similar or exact  matches is returned.
The product delivers its advanced retrieval  capabilities in an open,  flexible,
scalable and secure  architecture  and is designed to be easy to  implement  and
ready for extension.

Excalibur Video Analysis Engine (VAE)

Excalibur  Video  Analysis  Engine  is a toolkit  that  enables  developers  and
programmers to construct applications that analyze and re-purpose video content.
VAE  analyzes  any kind of  multi-media/video  asset  whether  it is  analog  or
digital,  allows  programmers  to  create  multi-threaded  applications  and has
enhanced scalability.  The toolkit is available as a Microsoft DirectShow filter
or C Library Developer's Kit. Based on the APRP(TM)  technology,  VAE plugs into
applications,  enabling  highly  accurate  event-change  detection.  VAE  uses a
caching  technique  which  compares a series of video  frames  based upon "event
detectors" dynamically selected by the calling program. The event detectors look
for specific occurrences in the video,  triggering "event alarms" appropriate to
the developer's application. Events include cuts, fades, and dissolves.

Excalibur Screening Room

Excalibur  Screening Room, which became generally available in the third quarter
of fiscal  year 1999,  is a  comprehensive  solution  for  real-time  capturing,
analyzing,  cataloguing,  browsing,  searching and retrieving  video, as well as
related  closed-caption text and metadata,  over corporate  intranets/extranets.
Excalibur    Screening   Room   is   aimed   at   entertainment    organizations
(film/television),  news organizations,  video production companies, advertising
agencies, publishing companies,  government agencies, Global 1,000 organizations
and  universities   with  large  video  archives  in  enterprise   training  and
communications departments. It enables users to easily capture analog or digital
video, automatically create an intelligent video storyboard, and play it back in
any of the industry's standard video file formats. Screening Room users can then
automatically  browse,  search, and retrieve precisely what video clips they are
looking for without having to play or watch the video in its entirety. Excalibur
Screening  Room  combines  the  APRP(TM)  technology  for  video  analysis  with
Excalibur  RetrievalWare's  indexing  capabilities.   Excalibur  Screening  Room
consists of four components:  Capture Client,  Edit Client,  Browser Client, and
Video Asset Server. The Capture Client captures, analyzes and storyboards analog
or digital video assets, including live feeds and associated closed caption text
and annotations,  for fast,  efficient  playback.  The Edit Client is for use by
persons  responsible for quality  assurance and editorial control of storyboards
and  metadata.  It  allows  browsing,  searching,  editing,  and  annotation  of
storyboards.  Users can  additionally  output new rough cut edit segments to EDL
(Edit Decision  Lists) for import into  higher-end  offline editing systems like
AVID and Media 100. The Browser  Client  allows user access to catalogs of video
assets  through any  standard Web  browser.  The Video Asset Server  indexes and
stores captured video assets for instantaneous browsing, search and retrieval in
a client/server  environment.  Excalibur Screening Room version 1.1, released in
the third quarter of fiscal year 1999,  features  expanded  streaming  media and
database  support for the  RealNetworks  G2 Media  Player,  the Sybase  Adaptive
Server, and added server support for the Sun Solaris platform.

with FileNET Corporation.  As part of the development agreement,  Excalibur will
integrate  RetrievalWare  with FileNET Panagon,  FileNET's  document  management
software.  This new synchronizer product enables end users to seamlessly execute
a single search for information in a variety of FileNET  document  repositories,
and other libraries and databases, including Lotus Notes and Microsoft Exchange,
and externally on the Internet.

In August  1998,  the  Company  announced  a  multi-year,  multi-million  dollar
licensing,  development  and  distribution  agreement  with  Storage  Technology
Corporation  ("StorageTek"),  a provider of network storage. The agreement gives
StorageTek rights to bundle  Excalibur's  advanced search and retrieval products
with its high-performance network storage products and then sell the packages as
enhanced  solutions  for knowledge  management  and digital  content  management
initiatives.  Under the agreement,  StorageTek gains distribution rights for the
full Excalibur  product line,  including  Excalibur  RetrievalWare and Excalibur
Screening Room.

In August  1998,  the Company  announced  an  agreement  with  Lernout & Hauspie
("L&H") whereby L&H will distribute  Excalibur  RetrievalWare and also integrate
RetrievalWare  into its multilingual  language  libraries  enabling it to create
products capable of simultaneous cross-lingual searches.  Cross-lingual searches
are  of  particular  benefit  to  online  publishing  applications  as  well  as
multinational corporate intranet implementations.

In  September  1997,   Sony  Marketing   (Japan)  Inc.   ("SMOJ")   announced  a
comprehensive licensing, integration and reseller agreement with the Company for
Excalibur's  family  of  knowledge   retrieval   software  products,   Excalibur
RetrievalWare and Excalibur Visual RetrievalWare.  Under the agreement, SMOJ has
licensed  Excalibur  RetrievalWare  and Excalibur Visual  RetrievalWare  and has
integrated  the  Japanese   morphology   system  and  dictionary   into  it  for
localization and resale in Japan.

In July 1997, the Company  entered into an agreement  with Saucedo  Enterprises,
who provides integration services to GTE Enterprise Solutions, a division of GTE
Corporation,  for the development of a GTE Enterprise  Solutions' product called
"The  Bastille".  The  Bastille is a web-based  service  available to all United
States law  enforcement  agencies  that  offers a secure,  private  network  for
information   sharing   and   communication   among  law   officers.   Excalibur
RetrievalWare  provides search,  retrieval and real-time profiling  capabilities
across several  different data  repositories  and allows  officers to share this
information  via a private  network on the Internet.  Revenues  derived from the
Company's agreement with Saucedo Enterprises were less than 10% of the Company's
total revenues in the fiscal year ended January 31, 1999.


                                       8

In  July  1996,  the  Company  authorized  the  use of  its  name  by  Excalibur
Technologies N. V. ("ETNV"), a Belgian company incorporated in June 1996 for the
purpose of selling and marketing the  Company's  products and services  within a
large territory  including most of Northern Europe and Italy. In connection with
the formation of ETNV, the Company acquired approximately 13.2% of ETNV's voting
capital stock.  The Company accounts for the investment in ETNV under the equity
method since it exercises significant influence over the operating and financial
policies  of  ETNV.  The  Company  granted  to ETNV an  exclusive  license  (the
"License") to distribute certain of the Company's products,  including Excalibur
EFS and  RetrievalWare,  to other  authorized  resellers  and  end-users  in the
territory for approximately  five years. The License provided for the payment to
the Company of minimum  license fees of $1,475,000  for fiscal year 1997 and the
payment of additional minimum license fees in each subsequent fiscal year of the
License.  In the  fourth  quarter  of fiscal  year  1999,  ETNV did not make the
contractually required payment totaling approximately $900,000.


Product Development and Advanced Research

The  Company's  primary   technologies  are  its  semantic  network   processing
techniques and its proprietary adaptive pattern recognition  processing software
(APRP(TM)).

Excalibur's  semantic network  leverages lexical knowledge at the highest level,
offering a system to search for specific word meanings enriched by related terms
and  concepts.  With semantic  networks,  users find  information  using natural
language processing.  Semantic networks  incorporate syntax,  morphology and the
actual meaning of words as defined by published dictionaries and other reference
sources.

APRP(TM) consists of a software  architecture for processing digital information
to extract  patterns in the primary types of  computerized  data:  text,  image,
signal and video. The system provides high-speed pattern recognition that can be
used to store,  categorize,  retrieve and refine data. The processing of digital
patterns  provides  users with a way to store and use  computerized  data faster
with more  flexibility and with fewer data storage  requirements  than competing
systems.   The  Company's  pattern  recognition  methods  use  neural  computing
techniques to process data in a non-algorithmic,  parallel fashion by generating
responses to input data.  Systems utilizing these methods are unlike traditional
computer systems and are now being used in areas where traditional  systems have
been inefficient,  such as natural language,  machine vision, robotics,  pattern
matching  and signal  recognition.  Neural  computing  systems are  "trained" by
processing data, not by programming. Once the system has extracted patterns from
the  digital  data,  these  patterns  can be  sorted,  labeled  and used to make
decisions.

The  Company's  research  and  development  program  focuses  on  enhancing  and
expanding on the capabilities of its Excalibur  RetrievalWare  and Visual suites
of products  to address  additional  markets  and  exploring  and  applying  its
proprietary  pattern   recognition   technology  in  new  areas  such  as  image
recognition,  character recognition and forms recognition.  The Company believes
the  market  is  emerging  for  search  products  that can  index  and  retrieve
unstructured  text and multimedia data types. To that end, the Company has begun
development of a multimedia server architecture to provide integrated multimedia
search and retrieval.

<PAGE>
Certain elements of the Company's  software products are supplied to the Company
by other  independent  software  vendors under license  agreements  with varying
terms. Pursuant to these agreements, the Company makes periodic royalty payments
based on either revenues or units. The  technologies  acquired by the Company in
this manner  include word  processing  filters,  optical  character  recognition
engines and dictionaries and thesauruses in electronic form.

The  Company  has  conducted   research  and  product   development  of  pattern
recognition  and  natural  language  systems  since 1980.  Research  and product
development expenditures for the development of new products and enhancements to
existing  products  were  approximately  $8.3 million,  $6.4  million,  and $6.3
million,  respectively,  in the fiscal years ended  January 31,  1999,  1998 and
1997.

Protection of Proprietary Technology

The  Company  regards its  software as  proprietary  and relies  primarily  on a
combination   of   copyright,   trademark  and  trade  secret  laws  of  general
applicability,  employee  confidentiality and invention  assignment  agreements,
software  distribution  protection  agreements and other  intellectual  property
protection  methods to  safeguard  its  technology  and software  products.  The
Company has not obtained patents on any of its technology; however on August 24,
1998, the Company filed an application  with the Patent and Trademark  Office to
obtain a patent on multimedia document  retrieval.  The Company also relies upon
its efforts to design and produce new products and upon improvements to existing
products to maintain a competitive position in the marketplace.

Competition

Competition  in the computer  and  communications  industry in general,  and the
software development industry in particular, is intense. The Company competes in
multiple markets,  including the traditional  information retrieval market. This
market has current and potential competitors who are larger and more established
than the Company and have significantly greater financial,  technical, marketing
and other  resources  than the  Company.  The Company  considers  its  principal
competitive  advantage to be the  architecture,  extensibility  to multiple data
types and performance of its products.  Specifically,  the Company believes that
compared to its primary  competition,  the Company's products provide users with
more accurate results due to the semantic network and APRP(TM) technologies,  an
environment  which is more scalable due to the distributed  search  architecture
and more comprehensive  searching due to the ability to search multiple types of
data. The Company differentiates its products by using new technology to provide
benefits  such  as  labor  savings  from  reduced   manual   pre-processing   or
organization  of data,  faster  retrieval,  access to many  kinds of data,  full
integration  with  network  architecture  and  more  forgiving   interaction  in
retrieving  information stored in computers.  The Company competes with numerous
companies  depending on the target market for their  products.  Most often,  the
Company competes directly with companies such as Verity, Inc. and Autonomy, Inc.
in the information  search and retrieval market.  The Company primarily competes
with Virage, Inc. in its visual product markets.  There can be no assurance that
the  Company  will be able to  compete  successfully  against  current or future
competitors  or that  competition  will  not  materially  adversely  affect  the
Company's operating results and financial condition.

The Company's  activities  currently are subject to no particular  regulation by
governmental agencies other than those routinely imposed on corporate businesses
and no such regulation is now anticipated.

Employees

The Company had 201  employees at January 31, 1999,  of whom 78 were in research
and development, 73 in sales and marketing, 23 in technical support and training
and  27 in  finance  and  administration.  The  employees  are  not  covered  by
collective  bargaining  agreements and the  management of the Company  considers
relations with employees to be good.  Competition for qualified personnel within
the Company's  industry is intense.  There can be no assurance  that the Company
will be able to continue to attract, hire, or retain qualified personnel and the
inability  to do so could  have a material  adverse  effect  upon the  Company's
operating results and financial condition.



Item 2. Properties.

The Company's corporate headquarters  facilities are occupied under two sublease
agreements that expire in calendar year 1999 for a total of approximately 18,700
square feet of space in an office building located at 1921 Gallows Road, Vienna,
Virginia  22182.  The  Company  has signed a new lease for the space that begins
upon  termination  of the current  sublease  in fiscal year 2000.  The new lease
expires in calendar year 2004.

The Company leases three facilities that serve primarily as software development

The three-year lease expires June 30, 2000.

The Company  leases office space in Windsor,  England and  Vitrolles,  France in
support of its international  sales operation.  Under these leases,  the Company
occupies approximately 3,400 square feet and 420 square feet, respectively.  The
two leases for the Windsor  offices  expire in calendar year 1999;  negotiations
are underway to extend the leases.  The  Vitrolles  lease is a rolling  contract
that requires a one-month cancellation notice.

The Company  believes  that its  facilities  are  maintained  in good  operating
condition and are adequate for its operations.

Item 7. Management's Discussion and Analysis of Financial
           Condition and Results of Operations.

Overview

The  statements  contained  in this  report that are not purely  historical  are
forward-looking  statements  within the meaning of Section 27A of the Securities
Act of 1933 and Section 21E of the  Securities  Exchange Act of 1934,  including
without  limitation  statements  about  the  Company's  expectations,   beliefs,
intentions or strategies  regarding the future. All  forward-looking  statements
included in this report are based on information available to the Company on the
date  hereof  and  the  Company   assumes  no  obligation  to  update  any  such
forward-looking  statements.  The  forward-looking  statements  contained herein
involve  risks and  uncertainties.  The  Company's  actual  results could differ
materially  from those  anticipated  in these  forward-looking  statements  as a
result of certain factors, including those set forth in this report.

The Company  principally  earns  revenues  from the  licensing  of its  software
products to commercial  businesses  and  government  agencies  throughout  North
America,  Europe and other parts of the world. The Company licenses its software
to end-users directly and also distributes its software products through license
agreements with value-added  resellers,  system integrators,  original equipment
manufacturers and other strategic partners. Revenues are provided under software
licenses with new  customers  and from the related sale of product  maintenance,
training  and  implementation  support  services.  Additions  to the  number  of
authorized users,  upgrades to newer product versions and the renewal of product
maintenance arrangements by customers pursuant to existing licenses also provide
revenues to the Company.  Under software  maintenance  contracts,  customers are
typically  entitled to receive  telephone  support,  software  bug fixes and new
releases of particular software products when and if they are released.

The Company's  software  products are designed to enable  individuals to quickly
search and  retrieve  relevant  information  residing  on a  LAN/WAN,  intranet,
paper-based archive,  extranet,  video archive or the Internet through a unified
web-based  user  interface.  There  are  generally  two  markets  today  for the
Company's  products,  text knowledge retrieval and video indexing and retrieval.
The  market  for  text  knowledge  retrieval  products  consists  of  electronic
publishing,  online  information  services,  global corporate  intranets,  paper
archival systems as well as market,  business and government  intelligence.  The
market for video  indexing and  retrieval  solutions  includes  application  and
website  developers,  certain  government  agencies as well as commercial media,

The Company believes that in addition to other competitive advantages,  it holds
a competitive  advantage in that the Company's products accommodate the indexing
and  retrieval of multiple  data types.  The Company  expects that over time, as
video becomes a more common data type, these two markets will merge.

On May 5, 1997, the Company acquired Interpix Software  Corporation,  located in
Santa Clara, California, a privately owned company and developer of a commercial
technology  enabling the collection,  indexing,  management and  presentation of
multimedia data on the Internet and corporate intranets.  The purchase method of
accounting was applied to this  acquisition  transaction and,  accordingly,  the
results  of   operations  of  Interpix  have  been  included  in  the  Company's
consolidated   results  of  operations  from  the  date  of   acquisition.   The
shareholders of Interpix received 275,000 shares of common stock of Excalibur in
exchange for all of the  outstanding  common  stock of  Interpix.  Approximately
$1,284,000  of the purchase  price was  allocated  to research  and  development
projects in process and was expensed in the second quarter of fiscal year 1998.

The Company  reorganized  its sales force and made other  changes to the overall
organization  at the end of the first quarter of fiscal year 1998. In connection
with these changes,  the Company reduced its workforce by approximately  10% and
recorded a restructuring charge of $577,000 in the first quarter of fiscal 1998.
The charge consisted of severance pay and benefits for terminated employees. All
payments associated with the restructuring  charge were paid prior to the end of
fiscal year 1998.


Results of Operations

For the fiscal year ended January 31, 1999,  total  revenues were $27.9 million,
an increase  of 25% over total  revenues  of $22.4  million in the prior  fiscal
year.  The net loss for the fiscal year ended January 31, 1999 was $3.9 million,
or $0.29 per common share,  compared to a net loss of $8.3 million, or $0.64 per
common share,  for the same period last fiscal year.  Excluding a charge of $1.3
million for in-process research and development expenses related to the Interpix
acquisition  and $0.6 million for  restructuring  charges,  the net loss for the
fiscal year ended  January 31, 1998 was $6.5 million.  Total  revenues in fiscal
year 1998 increased 11% from fiscal year 1997 revenues of $20.3 million. The net
loss for fiscal year 1997 was $7.2 million, or $0.58 per common share.

Revenues

Software  revenues  increased  from $15.9  million in fiscal  year 1997 to $17.2
million  in fiscal  year 1998 and to $22.7  million  in fiscal  year  1999.  The
increase in software  revenues in each  period was  attributable  to  increasing
market  awareness  and  acceptance  of the Company's  text  knowledge  retrieval
products,  contributions  from  existing  OEM partners  and  alliances  with new
partners  who chose the  Company as the key search  component  in their  product
offering.

                                       17

RetrievalWare,  which emerged as the Company's  dominant  product line in fiscal
year 1998,  continued that trend into fiscal year 1999.  Software  revenues from
RetrievalWare  increased  38% in fiscal  year 1999 to $20.9  million  from $15.1
million in the prior year. Software revenues for RetrievalWare were $8.6 million
in fiscal year 1997.  RetrievalWare  product  revenue now  represents 92% of all
software  revenues,  compared  to 88% and 54%,  in fiscal  years  1998 and 1997,
respectively.  With the  availability of  RetrievalWare  FileRoom,  EFS software
revenues  represented  only 1% of total  software  revenue in fiscal  year 1999,
compared to 9% and 41%,  respectively,  in fiscal years 1998 and 1997.  Software
revenues from the Visual  Products  Group  increased 196% in fiscal year 1999 to
$1.6  million from $0.5  million in the prior  fiscal  year.  Revenues  from the
Visual  Products Group were 7% of software  product  revenue in fiscal year 1999
compared to 3% and 5%, respectively, in fiscal years 1998 and 1997.

The  Company  generated  record  revenues  by  continuing  to attract  prominent
corporate customers in fiscal year 1999. While maintaining the Company's current
customer  base,  Excalibur  attracted new  customers  seeking  industry  leading
retrieval  technology  including ABC Inc.,  Copley Press, ICI Chemical,  British
Gas, the Capital Group and Virginia Power. In October 1998, the Company released
RetrievalWare  WebExpress,  a  high-performance,  search and retrieval  software
solution developed specifically for web publishers,  online services and content
providers  seeking more  accurate and  comprehensive  access to large volumes of
diverse  information  ranging from scanned paper to electronic text,  images and
video.  New  Excalibur   customers   choosing  Excalibur   WebExpress   included
Encyclopedia  Britannica,  Powerize.com,  Careerpath.com  and several government
online customers.

In fiscal year 1999,  the Company  generated  increased  revenues  through major
integration and software  distribution licenses with strategic partners. In July
1998, the Company signed a strategic  licensing,  development  and  distribution
agreement  with  Storage  Technology  Corporation  ("StorageTek").   Excalibur's
advanced retrieval software has been coupled with StorageTek's  high-performance
network storage products to create advanced solutions called Network Appliances.
StorageTek  committed to a prepaid license for licensing fees over 18 months and
will also pay  royalties  on resale of  current  Excalibur  products  and future
products to be jointly developed.  The Company recognized $2.3 million in fiscal
year 1999 related to the  agreement  using the  percentage-of-completion  method
based on the  relationship  of actual costs incurred to total costs estimated to
be incurred  over the  duration of the  contract;  the  remainder of the prepaid
license  payments will be recognized in fiscal year 2000. In the fourth  quarter
of fiscal  year 1999,  the Company  signed an  agreement  with Inso  Corporation
whereby Inso will  integrate  Excalibur  RetrievalWare  with the Inso Media Bank
media asset management solution and with their product data management solution.
The arrangement  also provides the basis for advanced  functionality in the form
of HTML export and viewer  technology  to be included in future  versions of all
Excalibur  products.  The  Company  recognized  $3 million  of revenue  from the
agreement in the fourth quarter of fiscal year 1999 relative to a five-year paid
up license to Inso Corporation.

Revenues  from  international  operations  are  provided  primarily  by software
licenses  with  various  European  commercial  and  government  customers  and a
well-established  European reseller network.  The Company's  international sales
operation, Excalibur Technologies International, Ltd. ("ETIL"), headquartered in
the United Kingdom  experienced  decreased  revenues in the current fiscal year.
International  revenues  excluding Canada dropped 6% in fiscal year 1999 to $7.3


                                       18
<PAGE>

million from $7.8 million in fiscal year 1998.  International revenues excluding
Canada were $5.9 million in fiscal year 1997.  International  software  revenues
were  negatively  impacted by  financial  difficulties  of ETNV,  the  Company's
primary continental European  distribution  channel. The Company recognized $0.8
million of  software  revenue  related to the ETNV  contract in fiscal year 1999
compared to $1.5  million in fiscal year 1998. A payment of  32,000,000  Belgian
Francs, or approximately $0.9 million, was due from ETNV to Excalibur in January
1999.  The  payment  was not made and  accordingly,  no  revenue  from  ETNV was
recorded  in the fourth  quarter.  The  Company's  revenues  from  international
operations  were also  negatively  affected by the Asian  financial  crisis that
impacted  Excalibur sales in the Pacific Rim. Revenues from the Pacific Rim were
10% less in fiscal year 1999  compared to 1998 and  decreased 15% in fiscal year
1998 compared to fiscal year 1997.

Software  maintenance and customer  support revenues were $5.2 million in fiscal
year 1999 and $5.2 million and $4.4 million,  respectively, in fiscal years 1998
and 1997.  Flat  maintenance  revenues in fiscal year 1999 compared to 1998 were
attributable  to the transition of the business from EFS to  RetrievalWare.  The
EFS customer base in general is not renewing their maintenance contracts.  While
this is  somewhat  offset  by growth in the  RetrievalWare  base of  maintenance
contracts  as  RetrievalWare  license  sales  grow,  the  overall  effect  was a
flattening  of  maintenance  in the current  fiscal year.  Maintenance  revenues
increased 19% in fiscal year 1998 compared to 1997. That increase was attributed
to additions to the RetrievalWare customer base.

Operating Expenses

Cost of sales increased from $3.2 million in fiscal year 1997 to $4.3 million in
fiscal year 1998 and to $5.1 million in fiscal year 1999,  representing 16%, 19%
and 18% of total sales, respectively.  The cost of sales increase in fiscal year
1999 was  attributable  to the higher  revenues and increased ETIL cost of sales
due to higher royalties for new language  versions of RetrievalWare  and greater
use of  partners.  The  increase  in cost of sales in fiscal  year 1998  related
primarily  to the  formation  of a  product  implementation  group at the end of
fiscal year 1997 which resulted in additional  salaries expense,  implementation
project  subcontractors  expense,  and increased  overhead  costs in fiscal year
1998. Additionally, due to the acquisition of Interpix in fiscal year 1998, cost
of sales contained associated amortization expense of intangible assets.

Sales and  marketing  expenses  increased  2% in fiscal  year  1999,  from $13.2
million in fiscal year 1998 to $13.5  million in fiscal year 1999.  The increase
in expenses resulted from personnel growth in ETIL and the marketing department.
Sales and  marketing  expenses were 48% of revenues in fiscal year 1999 compared
to 59% in fiscal  year 1998.  In fiscal  year 1998,  sales and  marketing  costs
decreased  9% to $13.2  million  from  $14.4  million in fiscal  year 1997.  The
reduction in expenses in fiscal year 1998  resulted from the  reorganization  in
the first quarter of fiscal year 1998.

Research and product  development  costs  increased  from $6.3 million in fiscal
year 1997 to $6.4 million in fiscal year 1998 and to $8.3 million in fiscal year
1999, representing 31%, 29% and 30% of revenues,  respectively.  The majority of
the increase in fiscal year 1999 was  attributable to the  establishment  of the
joint  development  lab  with  StorageTek.  The  lab has  integrated  StorageTek
products with Excalibur's advanced products for crawling,  indexing,  searching,
retrieving and distributing all enterprise  digital content,  to create advanced
solutions that make enterprise-wide information assets easier to archive, access

                                       19
<PAGE>

and leverage.  Established  in the third quarter of fiscal 1999, the lab focused
efforts to complete  development of StorageTek network appliance  products,  the
first of which was  delivered in March of 1999.  Text and visual  expenses  also
increased  as  the  Company  continued  to  invest  in  the  enhancement  of its
RetrievalWare  and  visual  product  lines.  In  fiscal  year  1998,   continued
development of Excalibur RetrievalWare products was emphasized while EFS product
development was  significantly  curtailed.  Increased costs  associated with the
development of  RetrievalWare  products were offset by the  diminished  expenses
associated with the EFS products. As a result,  research and product development
costs increased only 2% in fiscal year 1998.

General and  administrative  expenses  decreased  2% in fiscal year 1999 to $4.8
million  from $4.9  million  in fiscal  year 1998,  representing  17% and 22% of
revenues, respectively. The majority of the decrease in fiscal year 1999 was due
to a  reduction  in  corporate  expenses.  In  fiscal  year  1998,  general  and
administrative expenses increased 25% from $3.9 million in fiscal year 1997. The
increase was the result of increased  staffing and related  expenditures  in the
areas of human resources, information systems and financial analysis required to
support the Company's  growth.  Bad debt expense in fiscal years 1999,  1998 and
1997 was $493,000, $250,000, and $150,000, respectively.

In the second  quarter of fiscal year 1998,  the Company  recorded an expense of
$1.3 million for the cost of in-process research and development acquired in the
merger  with  Interpix.  This  acquisition  facilitated  the  broadening  of the
Company's  product line with the  introduction of Excalibur  Internet  Spider, a
multimedia  web crawler that  enables end users and  application  developers  to
access and leverage multimedia  information published on intranets and the World
Wide Web. Cost cutting  measures  taken in the first quarter of fiscal year 1998
helped offset the additional expenses  associated with the Interpix  development
group. Streamlining of the services department and a reduction of the work force
reduced employee related expenses of research and development.

The Company  reorganized  its sales force and made other  changes to the overall
organization  at the end of the first  quarter of fiscal year 1998.  The Company
reduced its workforce by approximately  10% and recorded a restructuring  charge
of $0.6 million in the first quarter.  The charge consisted of severance pay and
benefits  for  terminated   employees.   All   expenditures   relative  to  this
restructuring charge were made in fiscal year 1998.

The activities for fiscal year 1999,  including those discussed above,  resulted
in total expenses of $31.7  million,  a 4% increase from total expenses of $30.6
million in the prior fiscal year. In fiscal year 1998, total expenses  increased
by 10% from $27.9  million in fiscal year 1997.  The total  number of  employees
increased from 168 at the beginning of the current fiscal year to 201 at January
31, 1999. The Company had 173 employees at January 31, 1997.

Due to a decreased level of invested funds,  net interest income  decreased from
$0.8  million in 1997 to $0.4  million in 1998 and to $0.2  million in 1999.  As
discussed in Note 3 to the consolidated  financial  statements contained herein,
the Company recorded its equity in the net loss of its affiliate,  ETNV, for the
fiscal year ended  January 31, 1999.  This charge in fiscal 1999,  including the
amortization of the excess of the Company's  investment over the Company's share
of the underlying  net assets of ETNV and the  elimination by the Company of its
share of its gross profit  included in ETNV's prepaid license balance at January
31, 1999, was $0.3 million.  The corresponding charge was $0.5 million in fiscal
year 1998 and $0.3 million in fiscal year 1997.

Liquidity and Capital Resources

In the fiscal year ended  January 31, 1999,  the Company's  combined  balance of
cash, cash  equivalents and  investments in marketable  securities  decreased by
$0.6 million to $5.9 million as summarized below (in thousands).  At January 31,
1998 investments in marketable  securities consisted of U.S. Treasury Bills with
maturities of less than one year.

The  Company's  operating  activities  used cash of $3.0  million in fiscal year
1999.  The net loss of $3.9  million  was  offset by  non-cash  charges  of $1.8
million,  including $1.5 million in depreciation and amortization,  $0.5 million
in bad debt expense and $0.3 million for the Company's  share of the net loss of
ETNV and  amortization  of ETNV  warrants.  Reductions  in  accounts  receivable
provided  $2.3 million  while  increases in prepaid  expenses used $3.4 million.
Reductions in accounts payable, accrued expenses and deferred revenues used $0.3
million.

In  fiscal  year  1998,  cash  of $4.4  million  used  to  fund  operations  was
significantly  less than the $8.3 million net loss for the year due primarily to
several non-cash charges.  Those charges,  which totaled $3.4 million,  included
acquired  research  and  development  costs of $1.3  million,  depreciation  and
amortization of $1.5 million and the Company's share of the net loss of ETNV and
amortization  of ETNV warrants  totaling  $0.5  million.  Reductions in accounts
receivable and prepaid expenses provided $0.5 million.

During fiscal year 1999,  investing  activities provided $0.1 million.  Net cash
provided  from the maturity of U.S.  Treasury  Bills  totaled $1.5 million while
purchases  of  computer  and other  equipment  used $1.1  million.  Loans to and
investments in the Company's  affiliate,  ETNV,  included in other assets,  used
$0.2 million. In fiscal year 1998,  investing  activities provided $6.1 million.
Net cash of $6.9 million was provided from the maturity of U.S.  Treasury Bills.
Cash of $0.1  million  was also  provided  as a  result  of the  acquisition  of
Interpix.  Cash was used to purchase computer and other equipment  totaling $0.8
million and to make a $0.1 million loan to ETNV.

Financing  activities  provided  $3.8  million in fiscal  year  1999.  A private
placement  of  325,000  shares  of  common  stock to an  unaffiliated  financial
institution at a purchase price of $10.00 per share provided $3.3 million.  Cash
of $0.6 million was provided  from the  exercise of employee  stock  options and
issuances of stock under the employee  stock purchase plan. In fiscal year 1998,
the exercise of employee stock options and issuances of stock under the employee
stock purchase plan provided $0.6 million.

The number of days sales  outstanding  ("DSO")  at  January  31,  1999 was 61, a
decrease  from  116 days at  January  31,  1998.  Management  believes  that the
allowance for doubtful accounts of $0.7 million at January 31, 1999 is adequate.

As of January 31, 1999, the Company's  balances of cash and cash equivalents was
$5.9 million. The Company completed a private placement of 500,000 shares of its
common stock in March 1999 at a purchase price of $10 per share. Net proceeds of
$4.7 million from the  placement  will be used to fund  ongoing  operations  and
general  corporate  purposes of the Company.  The current  balance of cash, cash
equivalents  and  investments is expected to be sufficient to fund the Company's
current projected cash needs for the next fiscal year.

Historically,  the  Company  has  primarily  used cash  provided by sales of its
common stock to fund its  operating  losses.  If the actions taken by management
are not effective in achieving  profitable operating results, the Company may be
required to pursue  additional  external  sources of  financing in the future to
support its operations and capital requirements. There can be no assurances that
external  sources of  financing  will be  available  if  required,  or that such
financing will be available on terms acceptable to the Company.


Factors That May Affect Future Results

The Company's  business  environment is  characterized  by intense  competition,
rapid technological  changes,  changes in customer requirements and emerging new
market segments.  Consequently,  to compete  effectively,  the Company must make
frequent  new  product  introductions  and  enhancements  while  protecting  its
intellectual  property,  retain its key personnel and deploy sales and marketing
resources  to take  advantage of new business  opportunities.  Future  operating
results  will be  affected  by the  ability of the Company to expand its product
distribution  channels and to manage the expected growth of the Company.  Future
results may also be impacted by the  effectiveness  of the Company in  executing
future  acquisitions  and integrating the operations of acquired  companies with
those of the Company.  Failure to meet any of these  challenges  could adversely
affect future operating results.

The Company's quarterly operating results have varied  substantially in the past
and are likely to vary  substantially  from quarter to quarter in the future due
to a variety of factors. In particular, the Company's period-to-period operating
results  are  significantly  dependent  upon the timing of the  closing of large
license  agreements.  In this regard, the purchase of the Company's products can
require a significant  capital  investment  from a potential  customer which the
customer  generally  views  as a  discretionary  cost  that can be  deferred  or
canceled due to budgetary or other  business  reasons and can involve long sales
cycles of six  months or more.  Estimating  future  revenues  is also  difficult
because the Company  ships its products  soon after an order is received and, as
such does not have a significant  backlog.  Thus, quarterly license fee revenues
are  heavily  dependent  upon a  limited  number of  orders  for large  licenses
received  and  shipped  within  the same  quarter.  Moreover,  the  Company  has
generally  recorded a  significant  portion of its total  quarterly  license fee
revenues in the third month of a quarter, with a concentration of these revenues
occurring in the last half of that third month.  This  concentration of revenues
is influenced by customer tendencies to make significant capital expenditures at
the end of a fiscal  quarter.  The Company  expects  these  revenue  patterns to
continue for the foreseeable  future.  Despite the  uncertainties in its revenue


                                       22
<PAGE>

patterns,  the Company's  operating expenses are based upon anticipated  revenue
levels  and  such  expenses  are  incurred  on an  approximately  ratable  basis
throughout  a  quarter.  As a result,  if  expected  revenues  are  deferred  or
otherwise  not  realized in a quarter for any reason,  the  Company's  business,
operating  results  and  financial  condition  would  be  materially   adversely
affected.

As of January  31,  1999,  the  Company  had net  operating  loss  carryforwards
("NOLs") of approximately $67,957,000.  The deferred tax assets representing the
benefits of the NOLs have been offset completely by a valuation allowance due to
the Company's lack of an earnings  history.  The Company  incurred a net loss of
$3,854,000 for the fiscal year ended January 31, 1999. The  accumulated  deficit
of the Company at January  31,  1999 was  $55,798,000.  The  realization  of the
benefits of the NOLs is dependent on sufficient  taxable income in future fiscal
years.  Lack of future  earnings,  or a change in the  ownership of the Company,
could  adversely  affect the  Company's  ability to utilize  the NOLs.  Further,
because there was a change in the ownership of ConQuest in fiscal year 1996, the
Company's  ability  to  utilize  NOLs  relating  to  ConQuest  of  approximately
$3,233,000 may be limited.  Despite the NOL carryforwards,  the Company may have
income tax liability in future years due to the  application of the  alternative
minimum tax rules of the Internal Revenue Code.

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

The Company believes that inflation has not had a material effect on the results
of its operations to date.


Other Factors

Year 2000

On July 29, 1998,  the  Securities  and Exchange  Commission  issued  additional
guidance on disclosures  that public  companies  should make related to the Year
2000.  The new release was effective for the Company's  October 31, 1998 interim
reporting.  In addition  to  historical  information,  the  disclosure  contains
forward-looking statements within the meaning of the "safe harbor" provisions of
the Private Securities  Litigation Reform Act of 1995. Such statements are based
on  management's  current  expectations  and are subject to a number of factors,
risks and  uncertainties  which could cause actual results to differ  materially
from those described in the forward-looking statements.

State of Readiness
The  Company  currently  has  facilities  in six  locations,  each of  which  is
responsible for its own development information technology systems, herein known
as "Non-IT systems",  while corporate  information  technology  systems,  herein
known as "IT  systems",  are  managed by the  Company's  Management  Information
Systems  department  ("MIS").  For the  purposes  of Year 2000  compliance,  the
corporate  MIS  department  is managing the task of  verifying  that all Company
systems are date  compliant,  including  reviewing and analyzing all development


                                       23
<PAGE>

platforms,  not directly under MIS control.  This umbrella process was initiated
in order to ensure the Company would be able to continue developing its products
without  disruption  after January 1, 2000. To ensure that Non-IT and IT systems
are, or will be,  compliant;  the Company  has  undertaken  a full survey of all
systems within the Company at all locations. This survey covers all user desktop
and laptop systems; all IT systems, servers, and operating systems; all critical
applications,   including  financial,   accounting,  corporate  database,  human
resources and administrative systems; and all Non-IT systems, servers, operating
systems and third party coding products.  The majority of the Company's  efforts
regarding  Year 2000  readiness are  associated  with  internal data  processing
systems.  In all material  respects,  products  manufactured  by the Company are
already  Year 2000  compliant,  although  the  individual  platforms  upon which
product(s) are developed are still under review and analysis.  Due to the recent
upgrade of many of the  Company's IT systems,  the majority of these systems are
either currently  prepared for Year 2000 in all material  respects or are in the
process of being upgraded to standardized  systems and  applications  which will
meet this objective. Most IT systems and applications which are deemed Year 2000
compliant  by the  software  vendors are tested by the  Company to verify  these
claims.  At this time,  critical  financial,  accounting and corporate  database
systems have been tested, and Non-IT systems are in the process of being tested.
These testing  proportions  are related to both the magnitude and perceived risk
of system non-compliance and future testing will be scheduled in accordance with
these criteria.  For the remaining IT systems and the Non-IT systems, plans with
critical dates are being developed to monitor the Company's  progress toward the
overall objective of Year 2000 compliance.  The Company's  anticipates readiness
for Year 2000 by early in the fourth quarter of fiscal year 2000.

Costs to Address Year 2000 Issues
Historical  and  estimated  costs of  remediation  to this  point  have not been
material.  The Company has resolved IT systems  compliance issues through normal
replacement  and upgrades of software.  Non-IT systems are being  addressed on a
case by case basis through the use of existing MIS resources. Most of the Non-IT
systems remedial  activity to this point has involved  applying low or zero cost
patches to operating  systems and  platforms  using  existing  MIS  resources to
achieve a date compliance  level. The Company will continue to monitor Year 2000
remediation costs and will update its estimate of future  remediation  costs, if
any, as it completes its Non-IT systems analysis.

Key Considerations and Contingency Plans
At the current time, the Company's Year 2000  readiness  plan  anticipates  that
both IT and Non-IT systems and  applications  will be Year 2000 compliant in all
material  respects  by early in the  fourth  quarter of fiscal  year 2000.  This
assessment is based on the Company's  analysis to date and detailed  findings at
its  Vienna,  Virginia  and  Columbia,  Maryland  locations.  There  can  be  no
assurance, however, of complete compliance based on the status to date. However,
since the Company is not  dependent  upon any single IT or Non-IT system for the
majority  of its  revenue,  it is unlikely  that any single  system will have an
adverse  effect on the Company as a whole.  Contingency  plans will  involve the
procurement  of newer  platforms  for Non-IT  systems and the  temporary  use of
standardized  commercial  off-the-shelf  replacement modules for IT applications
and  business  functions.  While at present  there are no  indications  that any
contingency  plans will be necessary or that there will be revenue  disruptions,
there can be no assurances that this will necessarily be the case.

EURO Conversion

On January 1, 1999, the exchange rates of eleven countries (Germany, France, the
Netherlands,  Austria,  Italy, Spain, Finland,  Ireland,  Belgium Portugal,  and
Luxembourg)  were fixed  amongst one another  and became the  currencies  of the
EURO.  The currencies of the eleven  countries will remain in circulation  until
mid-2002.  The EURO currency will be introduced on January 1, 2002.  The Company
does not expect future  balance sheets and statements of earnings and cash flows
to be materially impacted by the EURO Conversion.


New Accounting Pronouncements

The Company adopted  Statement of Financial  Accounting  Standards  ("SFAS") No.
130, "Reporting  Comprehensive Income," during the first quarter of fiscal 1999.
SFAS 130 requires  additional  disclosures  with  respect to certain  changes in
assets and  liabilities  that  previously  were not  required  to be reported as
results of operations for the period.

In 1998, the Company  adopted  Statement of Financial  Accounting  Standards No.
131,  "Disclosures about Segments of an Enterprise and Related Information." FAS
131  supercedes  FAS  14,  "Financial  Reporting  for  Segments  of  a  Business
Enterprise",  replacing the "industry  segment"  approach with the  "management"
approach.  The management approach designates the internal  organization that is
used by management for making operating  decisions and assessing  performance as
the  source  of  the  Company's  reportable  segments.  FAS  131  also  requires
disclosures  about products and services,  geographic areas and major customers.
The  adoption  of FAS 131 did not affect  results  of  operations  or  financial
position  but did affect the  disclosures  of segment  information.  The Company
accounts for all operations as one segment.

In June 1998, the Financial  Accounting Standards Board ("FASB") issued SFAS No.
133, "Accounting for Derivative  Instruments and Hedging Activities," which will
be effective  for the Company's  fiscal year 2001.  This  statement  establishes
accounting and reporting standards  requiring that every derivative  instrument,
including  certain  derivative  instruments  embedded  in  other  contracts,  be
recorded in the balance  sheet as either an asset or  liability  measured at its
fair value.  The statement also requires that changes in the  derivative's  fair
value be recognized in earnings  unless specific hedge  accounting  criteria are
met. The Company  believes the adoption of SFAS No. 133 will not have a material
effect on the financial statements.

The American  Institute of Certified Public  Accountants has issued Statement of
Position 98-9,  "Modification of SOP-97-2,  Software Revenue  Recognition,  With
Respect to Certain Transactions." SOP 98-9 is effective for revenue transactions
entered into in the  Company's  fiscal year 2001.  The Company has evaluated SOP
98-9 and does not  believe  its  adoption  will  have a  material  effect on the
financial statements.

Item 7A.  Market Risk

The Company's market risk is principally confined to changes in foreign currency
exchange  rates and  potentially  adverse  effects of differing tax  structures.
International revenues from ETIL, the Company's foreign sales subsidiary located
in the United Kingdom,  were  approximately  26% of total revenue in fiscal year
1999.  International sales are made mostly from the Company's foreign subsidiary
and  are  typically   denominated  in  British   pounds,   the  local  currency.
Additionally,  the subsidiary incurs most of its expenses in the local currency.
Accordingly, the local currency is ETIL's functional currency.

The Company's exposure to foreign exchange rate fluctuations arises in part from
intercompany  accounts in which costs  incurred in the United States are charged
to ETIL. The Company is also exposed to foreign  exchange rate  fluctuations  as
the financial results of ETIL are translated into U.S. dollars in consolidation.
As exchange rates vary, those results when translated may vary from expectations
and adversely impact overall expected profitability.


Item 8. Financial Statements and Supplementary Data.

Financial  statements and  supplementary  data of the Company are submitted as a
separate section of this Annual Report on Form 10-K.


Item 9. Changes in and Disagreements with Accountants on Accounting and 
        Financial Disclosure.

None.

Beneficial Ownership Reporting Compliance

thereunder require the Company's  executive officers and directors,  and persons
who own more that ten  percent of a  registered  class of the  Company's  equity
securities,  to file reports of initial  ownership and changes in ownership with
the SEC.  Based  solely on its  review of copies of such forms  received  by the
Company,  or on written  representations  from certain reporting persons that no
other reports were required for such persons,  the Company  believes that during
or with  respect to the period from  February 1, 1998 to January 31, 1999 all of
the Section 16(a) filing  requirements  applicable  to its  executive  officers,
directors and ten percent shareholders were complied with on a timely basis.

To the Stockholders and Board of Directors of
Excalibur Technologies Corporation:


In our  opinion,  the  consolidated  financial  statements  listed  in the index
appearing under Item 14(a)(1)  present  fairly,  in all material  respects,  the
financial position of Excalibur Technologies Corporation and its subsidiaries at
January 31, 1999,  and the results of their  operations and their cash flows for
the  year  then  ended,  in  conformity  with  generally   accepted   accounting
principles.  In addition,  in our opinion,  the financial statement schedule for
the year  ended  January  31,  1999,  listed in the index  appearing  under Item
14(a)(2)  presents fairly, in all material  respects,  the information set forth
therein  when  read in  conjunction  with  the  related  consolidated  financial
statements.  These financial statements and financial statement schedule are the
responsibility of the Company's management;  our responsibility is to express an
opinion on these financial  statements and financial statement schedule based on
our  audit.  We  conducted  our audit of these  statements  in  accordance  with
generally accepted auditing standards which 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,
assessing the  accounting  principles  used and  significant  estimates  made by
management,  and evaluating the overall  financial  statement  presentation.  We
believe  that our audit  provides a reasonable  basis for the opinion  expressed
above.

                                AND SUBSIDIARIES
                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS


(1)   THE COMPANY

Operations and Organization

The  consolidated   financial  statements  include  the  accounts  of  Excalibur
Technologies Corporation ("Excalibur") and its wholly owned subsidiaries.  These
entities  are  collectively  referred  to  hereinafter  as  the  "Company."  All
significant intercompany transactions and accounts have been eliminated.

The Company designs, develops and markets enterprise-wide accurate, scalable and
secure  knowledge  retrieval and digital  asset  management  software  solutions
capable of supporting  paper,  text,  image and video data.  The Company  offers
consulting,  training, product maintenance and system implementation services in
support of its software  products.  The Company  licenses its software  products
directly to commercial  businesses  and  government  agencies  throughout  North
America,  Europe and other parts of the world and also  distributes its software
products to end users through  license  agreements with  value-added  resellers,
system  integrators,   original  equipment  manufacturers  and  other  strategic
partners.

The Company has incurred  cumulative losses of approximately  $19.4 million over
the last  three  fiscal  years and the  accumulated  deficit  of the  Company at
January 31, 1999 was $55.8  million.  The  Company's  operations  are subject to
certain risks and uncertainties including, among others, the dependence upon the
timing of the closing on sales of large software licenses;  actual and potential
competition by entities with greater financial resources,  experience and market
presence  than the  Company;  rapid  technological  changes;  the success of the
Company's  product  marketing  and product  distribution  strategies;  the risks
associated with  acquisitions and  international  expansion;  the need to manage
growth; the need to retain key personnel and protect intellectual  property; and
the  availability  of additional  capital  financing on terms  acceptable to the
Company.

The  Company's  balances of cash and cash  equivalents  at January 31, 1999,  in
addition to net proceeds of $4.7 million from a private placement in March 1999,
are expected to provide  sufficient cash to meet the Company's current projected
needs for the next fiscal year. Historically, the Company has used cash provided
primarily  from sales of its common stock to fund its operating  losses.  If the
Company fails to achieve its operating  plan for fiscal year 2000, the Company's
balance of cash and cash equivalents may be reduced  substantially.  The Company
may be required to pursue  additional  external  sources of financing to support
its operations and capital requirements. There can be no assurance that external
sources of financing will be available to fund the Company's ongoing  operations
or other capital requirements on terms acceptable to the Company.

Acquisition of Interpix Software Corporation

On May 5, 1997, the Company acquired Interpix Software  Corporation,  located in
Santa Clara, California, a privately owned company and developer of a commercial
technology  enabling the collection,  indexing,  management and  presentation of


                                      F-7
<PAGE>

multimedia data on the Internet and corporate intranets.  The purchase method of
accounting was applied to this  acquisition  transaction and,  accordingly,  the
results of operations  of Interpix  were included in the Company's  consolidated
results of operations  from the date of  acquisition.  The results of operations
for Interpix prior to the acquisition were not material.

The  shareholders  of  Interpix  received  275,000  shares  of  common  stock of
Excalibur in exchange for all of the outstanding  common stock of Interpix.  The
total  purchase  price  included  the  value of the  Excalibur  shares  totaling
$1,822,000  and  out-of-pocket  acquisition  costs  that  totaled  $45,000.  The
purchase price was allocated to the assets purchased and the liabilities assumed
based  upon  their  fair  values  on  the  date  of  acquisition.  Approximately
$1,284,000  of the purchase  price was  allocated  to research  and  development
projects in process and was expensed upon the effective date of the acquisition.
The  excess  of the  purchase  price  over the fair  value of the net  assets of
Interpix was approximately  $575,000.  This amount represents  intangible assets
related to the completed technology base, the assembled workforce and tradenames
acquired,  is included in other assets in the consolidated balance sheet, and is
being amortized on a straight-line basis over five years.  Amortization  expense
for the year ended January 31, 1999 was  approximately  $111,000 and accumulated
amortization at January 31, 1999 was $192,000.


(2)    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 assets  and  liabilities  and  disclosure  of
contingent  assets and  liabilities at the date of the financial  statements and
the  reported  amounts of revenues  and expenses  during the  reporting  period.
Actual results could differ from those estimates.

Revenue Recognition

The American  Institute of Certified Public  Accountants has issued Statement of
Position 97-2,  "Software  Revenue  Recognition,"  ("SOP 97-2") that  supersedes
Statement of Position 91-1. The Company has  implemented SOP 97-2 in fiscal year
1999 and it has not had a material financial impact on the Company.

Revenues  from  the sale of  computer  software  licenses  are  recognized  upon
shipment of product provided that the fee is fixed and determinable,  persuasive
evidence of an agreement  exists and  collection of the resulting  receivable is
considered probable.  Revenues related to agreements with customers that contain
future performance requirements are recognized when the performance requirements
are satisfied.  Revenues related to customer support agreements are deferred and
recognized ratably over the term of the respective agreements, which are usually
one year in length.

Customization is sometimes involved in the development of a software solution by
the Company. Under these circumstances,  the Company's revenues are derived from
fixed    price    contracts    and    revenue    is    recognized    using   the
percentage-of-completion  method  based  on the  relationship  of  actual  costs
incurred  to total  costs  estimated  to be  incurred  over the  duration of the
contract.

                                      F-8
<PAGE>


Research and Development Costs

Software  development  costs are  included in research and  development  and are
expensed as incurred.  Statement of Financial  Accounting Standards ("SFAS") No.
86,  "Accounting  for the  Cost of  Computer  Software  to be  Sold,  Leased  or
Otherwise Marketed" requires the capitalization of certain software  development
costs once technological feasibility is established, which the Company generally
defines  as  completion  of a  working  model.  Capitalization  ceases  when the
products  are  available  for  general  release  to  customers,  at  which  time
amortization of the capitalized  costs begins on a straight-line  basis over the
estimated  product life, or on the ratio of current  revenues to total projected
product  revenues,  whichever is greater.  To date, the period between achieving
technological feasibility and the general availability of such software has been
short, and software  development costs qualifying for  capitalization  have been
insignificant.  Accordingly,  the  Company  has  not  capitalized  any  software
development costs.

Cash, Cash Equivalents and Marketable Securities

For purposes of the  consolidated  balance  sheets and statements of cash flows,
the Company considers all highly liquid investments purchased with a maturity of
three months or less to be cash  equivalents.  U.S.  government  securities  are
considered to be investments and are excluded from cash  equivalents  regardless
of their maturities. Cash equivalents consist of funds deposited in money market
accounts.  Consequently,  the  carrying  amount  of cash  and  cash  equivalents
approximates  fair value.  The Company  classifies its marketable  securities as
held-to-maturity  securities.  Accordingly,  marketable  securities,  consisting
entirely  of U.S.  government  securities,  are  carried at cost,  adjusted  for
premium and discount amortization. At January 31, 1998, the aggregate fair value
of the securities based upon quoted market prices was $1.5 million.

Income Taxes

Deferred taxes are provided utilizing the liability method as prescribed by SFAS
No.  109,  "Accounting  for  Income  Taxes,"  whereby  deferred  tax  assets are
recognized  for  deductible  temporary  differences  and operating  loss and tax
credit  carryforwards  and deferred tax  liabilities  are recognized for taxable
temporary  differences.  Temporary  differences are the differences  between the
reported  amounts of assets and  liabilities  and their tax bases.  Deferred tax
assets and  liabilities  are adjusted for the effects of changes in tax laws and
rates on the date of  enactment.  Deferred tax assets are reduced by a valuation
allowance  when, in the opinion of  management,  it is more likely than not that
some portion or all of the deferred tax assets will not be realized. The Company
has provided a full valuation allowance against its net deferred tax asset as of
January 31, 1999 and 1998, respectively.

Equipment and Leasehold Improvements

Office  furniture and computer  equipment are recorded at cost.  Depreciation of
office  furniture  and equipment is provided on a  straight-line  basis over the
estimated useful lives of the assets, generally three to ten years. Amortization
of leasehold  improvements is provided on a straight-line basis over the shorter
of the term of the applicable lease or the useful life of the asset.



                                      F-9
<PAGE>

Expenditures  for normal  repairs and  maintenance  are charged to operations as
incurred.  The cost of property and equipment  retired or otherwise  disposed of
and the related  accumulated  depreciation or amortization  are removed from the
accounts and any resulting gain or loss is reflected in current operations.

Net Loss Per Common Share

Basic  earnings  per share  includes no dilution and is computed by dividing net
loss available to common  stockholders by the weighted  average number of common
shares outstanding for the period. Diluted loss per share includes the potential
dilution that would occur if securities or other contracts to issue common stock
were  exercised or converted  into common stock.  Options to purchase  2,561,423
shares of common stock, warrants to purchase 148,500 shares of common stock with
exercise  prices  ranging  from  $1.04  to  $22.50  per  share,  and  cumulative
convertible  preferred stock that were  outstanding at January 31, 1999 were not
included in the  computation  of diluted loss per share as their effect would be
anti-dilutive.  As a result,  the basic and diluted  loss per share  amounts are
identical.

Translation of Foreign Financial Statements

Assets and liabilities of foreign operations are translated at the year-end rate
of exchange.  Statements  of operations  are  translated at the average rates of
exchange  during the year.  Gains or losses from  translating  foreign  currency
financial  statements are accumulated in a separate  component of  shareholders'
equity.

Concentrations of Credit Risk

Financial  instruments that potentially subject the Company to concentrations of
credit risk consist  primarily of cash  equivalents,  marketable  securities and
accounts  receivable.  Management believes that the Company's  investment policy
limits the  Company's  exposure to  concentrations  of credit risk.  The Company
sells its products primarily to major corporations,  including distributors that
serve a wide variety of U.S. and foreign  markets,  and to government  agencies.
The Company extends credit to its corporate  customers based on an evaluation of
the customer's  financial  condition,  generally  without requiring a deposit or
collateral.  Exposure to losses on receivables is principally  dependent on each
customer's  financial  condition.  The Company  monitors its exposure for credit
losses and  maintains an allowance  for  anticipated  losses.  The allowance for
doubtful  accounts was $660,000 and $527,000  respectively,  at January 31, 1999
and 1998.

Impairment of Long-lived Assets

The Company periodically  evaluates the recoverability of its long-lived assets.
This  evaluation  consists of a comparison  of the carrying  value of the assets
with the assets'  expected future cash flows,  undiscounted and without interest
costs.  Estimates  of expected  future cash flows  represent  management's  best
estimate based on reasonable and supportable assumptions and projections. If the
expected future cash flow,  undiscounted and without interest  charges,  exceeds
the carrying value of the asset, no impairment is recognized.  Impairment losses
are measured as the difference  between the carrying value of long-lived  assets
and their fair value.

(3)   INVESTMENT IN AFFILIATE

In  July  1996,  the  Company  authorized  the  use of  its  name  by  Excalibur
Technologies N. V. ("ETNV"), a Belgian company incorporated in June 1996 for the
purpose of selling and marketing the  Company's  products and services  within a
large  territory  including  most of  Northern  Europe  and Italy.  The  Company
contributed approximately $488,000 in cash to ETNV in consideration for 13.2% of
its voting  capital  stock.  In connection  with the  organization  of ETNV, the
Company issued warrants to purchase 148,500 shares of the Company's common stock
to certain  shareholders  of ETNV.  The warrants are  exercisable  at a price of
$22.00  per share for a term of seven  years but only if ETNV  achieves  certain
financial  objectives.  The  value of the  warrants  on the  date of  grant  was
estimated to be $758,000 and is included,  net of amortization,  in other assets
in the consolidated balance sheets.

The Company's  investment in ETNV is accounted for using the equity method.  The
investment  exceeded the Company's share of the underlying net assets of ETNV by
approximately  $827,000.  The excess is being amortized over a five-year period.
The  amortization  of the excess,  as well as the Company's  share of ETNV's net
loss for the period and the  elimination of the Company's  share of gross profit
included in ETNV's prepaid license fees at January 31, 1999 and 1998 is included
in equity in net loss of affiliate in the accompanying  consolidated  statements
of operations  for the fiscal years ended January 31, 1999,  1998 and 1997.  The
net  balances  of the  investment  in and  advances to ETNV is included in other
assets in the accompanying  consolidated balance sheets. At January 31, 1999 and
1998, the investment balance was $471,000 and $544,000, respectively.

The Company  granted to ETNV an exclusive  license (the "License") to distribute
certain of the Company's products to other authorized resellers and customers in
the territory for approximately five years. If the revenues of ETNV in the fifth
year exceed a certain level, the License shall  automatically be renewed. If the
License is not renewed, the other shareholders of ETNV may exercise an option to
sell their  shares to the Company  according  to a  revenue-based  formula.  The
Company  recorded  total revenues of $938,675 and $1,656,000 in the fiscal years
ended January 31, 1999 and 1998,  respectively,  related to the License.  In the
fourth quarter of fiscal year 1999, ETNV did not make its contractually required
payment totaling approximately $900,000.

After a term of approximately  five years, the Company may exercise an option to
purchase  all of the capital  stock of ETNV under  certain  conditions  and at a
price determined in accordance with a revenue-based  formula.  In the event that
the Company does not exercise its option,  the other  shareholders are permitted
to sell their shares, subject to certain limitations,  through a private sale or
public  offering.

(4)   CAPITALIZATION

Stock Offerings

During the second quarter of fiscal year 1999,  the Company  completed a private
placement  of  325,000   shares  (the  "Shares")  of  its  common  stock  to  an
unaffiliated  financial  institution.  The Company sold the Shares at a purchase
price of $10.00 per share, representing the approximate fair market value of the
stock  on the  date  of  issuance,  resulting  in  proceeds  to the  Company  of
$3,250,000.  The transaction was placed directly by the Company. The Shares were
sold  pursuant  to an  exemption  from  the  registration  requirements  of  the
Securities Act of 1933.


Cumulative Convertible Preferred Stock

The Company has issued 271,000 shares of cumulative convertible preferred stock.
The cumulative  convertible  preferred stock is convertible into common stock at
the rate of 10  shares  of common  stock  per  share of  cumulative  convertible
preferred  stock.  Holders of the  cumulative  convertible  preferred  stock are
entitled to receive cumulative  dividends of $0.50 per share per annum,  payable
annually on April 1 if declared by the Board of Directors,  in cash or shares of
common stock (to be determined by the Board of Directors) valued at the lower of
$1.00 per share or the market  price on the date of  declaration.  The amount of
accumulated dividends that have not been declared or accrued at January 31, 1999
is approximately $56,000.

In the event of voluntary liquidation,  dissolution or winding-up of the Company
or upon any distribution of assets, whether voluntary or involuntary, holders of
the convertible  preferred stock would have a liquidation  preference of $10 per
share,  plus accrued and unpaid  dividends over holders of the Company's  common
stock.


(5)   EMPLOYEE BENEFIT PLANS

Stock Options

The Company has adopted certain stock option plans to attract, retain and reward
key employees.  The plans are administered by a Committee appointed by the Board
of Directors, which has the authority to determine which officers, directors and
key employees are awarded options pursuant to the plans and the terms and option
exercise prices of the stock options. In addition,  from time to time, the Board
of Directors  awards stock options outside the plans; no such awards occurred in
fiscal years 1999,  1998 or 1997. Of the total number of shares  authorized  for
stock options,  options to purchase 2,561,423 shares are outstanding and 557,530
shares are available for future grants.

Each  qualified  incentive  stock  option  granted  pursuant to the plans has an
exercise price equal to the fair market value of the underlying  common stock at
the date of grant, a ten-year term and typically a four-year  vesting period.  A
non-qualified option granted pursuant to the plans may contain an exercise price
that is below the fair  market  value of the  common  stock at the date of grant
and/or may be  immediately  exercisable.  The term of  non-qualified  options is
usually  five or ten  years.  The  Company  records  expense  related to certain


                                      F-12
<PAGE>

non-qualified options and other stock-based compensation based on the difference
between  the fair market  value of the  underlying  common  stock at the date of
award and the exercise  price,  if any,  over the vesting  period.  There was no
expense  related to  stock-based  compensation  awards  recorded in the accounts
during fiscal year 1999, 1998 or 1997.

The following table summarizes the Company's activity for all of its stock
option awards:

On May 7, 1997,  the Board of  Directors  authorized a repricing  program  which
allowed  active  current  employees  to  elect to  reprice  all or some of their
outstanding  options to purchase shares of the Company's  common stock,  granted
under the 1989 and the 1995  Incentive  Plans and ranging in exercise price from
$5.50 to $29.53 per share, to $4.75, the closing price of Excalibur common stock
on May 7, 1997.  Options to purchase  approximately  1,176,000  shares of common
stock were  repriced.  Stock options that were already  vested and repriced were
not exercisable until November 8, 1997.

Options to purchase  1,796,090,  1,530,918 and 1,738,246 shares of the Company's
common stock were vested and  exercisable  at January 31,  1999,  1998 and 1997,
respectively, at weighted-average exercise prices of $8.64, $8.89 and $10.56 per
share, respectively.

The Company adopted the disclosure requirements of SFAS No. 123, "Accounting for
Stock-Based   Compensation,"  effective  for  the  Company's  January  31,  1997
consolidated  financial  statements.  The Company applies APB Opinion No. 25 and
related Interpretations in accounting for its plans.  Accordingly,  compensation
cost has been recognized for its stock plans based on the intrinsic value of the
stock option at date of grant (i.e.,  the difference  between the exercise price
and the fair value of the Company's common stock).

Had  compensation  cost for the Company's  stock-based  compensation  plans been
determined  based on the fair value at the grant  dates for awards  under  those
plans made in fiscal  years 1999,  1998 and 1997  consistent  with the method of
SFAS No.123, the Company's net loss and loss per share would have been increased
to the pro forma amounts  indicated below (amounts in thousands except per share
data).

The  weighted  average  fair value per share for stock  option  grants that were
awarded  in  fiscal  years  1999,  1998 and 1997 was  $4.77,  $4.24  and  $9.76,
respectively.

Employee Stock Purchase Plan

In  June  1996,   the  Company's   shareholders   approved  the  adoption  of  a
non-compensatory  stock purchase plan for all active  employees.  Of the 250,000
shares of common  stock that were  reserved  for  issuance  thereunder,  18,652,
40,252 and 3,253 shares were  purchased  by employees in fiscal year 1999,  1998
and 1997,  respectively.  The plan  provides  that  participating  employees may
purchase  common  stock each plan quarter at a price equal to 85% of the closing
price at the end of the quarterly period. Payment for the shares is made through
authorized payroll deductions of up to 10% of eligible annual compensation.

Deferred Compensation

ConQuest  Software Inc., a private software company acquired in June 1995 by the
Company,  entered into arrangements with certain of its officers,  employees and
independent  consultants  to defer a  portion  of their  compensation.  Deferred
compensation  of  employees  is  restricted  for use in the  exercise  of  stock
options. However, if an employee's options expire because the option terms lapse
or because employment  terminates,  the employee may request cash redemption one
year after expiration,  with 90 days notice.  During fiscal years 1999, 1998 and
1997, deferred compensation of $161,000, $654,000 and $99,000, respectively, was
settled. The portion of the deferred compensation balance related to independent
consultants was settled in fiscal year 1998.

Employee Savings Plan

The Company has an employee  savings plan that qualifies under Section 401(k) of
the Internal Revenue Code. Under the plan,  participating  eligible employees in
the United  States may defer up to 20 percent of their pre-tax  salary,  but not
more than  statutory  limits.  ConQuest had a similar plan  established  for the
benefit of its  employees  that was merged  into the  Company's  plan  effective
December 31, 1996.  The Company did not make any  contributions  to the employee
savings plan in fiscal years 1999, 1998, or 1997.


(6)   INCOME TAXES

As the Company  incurred  pretax losses for the fiscal years  presented  herein,
there are no income taxes provided in the accompanying  consolidated  statements
of  operations.  At  January  31,  1999,  the  Company  had net  operating  loss
carryforwards ("NOLs") of approximately $67,957,000 that expire at various dates
through  fiscal  year  2014.  The  realization  of the  benefits  of the NOLs is
dependent on sufficient  taxable  income in future fiscal years.  Lack of future
earnings,  a change in the ownership of the Company,  or the  application of the
alternative  minimum tax rules could adversely  affect the Company's  ability to

                                      F-15
<PAGE>
utilize  the NOLs.  Further,  because  there was a change  in the  ownership  of
ConQuest in fiscal year 1996,  the Company's  ability to utilize NOLs related to
ConQuest's operations of approximately $3,233,000 may be limited.

The  Company's  net  deferred  tax assets at January  31, 1999 and 1998 were as
follows (in thousands):

                                                  1999              1998

Though  management  believes that future net operating income and taxable income
of the Company may be sufficient to utilize a substantial amount of the benefits
of the Company's net operating  loss  carryforwards  and to realize its deferred
tax assets,  a valuation  allowance has been recorded to offset  completely  the
carrying  value of the  deferred tax assets due to the  Company's  lack of prior
earnings and the size of the accumulated deficit.


(7)    COMMITMENTS AND CONTINGENCIES

Lease Commitments

The Company conducts its operations using leased office  facilities.  The leases
terminate  at various  dates  through  fiscal year 2004.  The  Company  also has
operating leases for automobiles at its foreign  subsidiary that are included in
the figures below. Future minimum rental payments under non-cancelable operating

Employment Agreements

Under an agreement between the Company and Patrick C. Condo, President and Chief
Executive  Officer  entered  into in May 1998,  Mr. Condo will be paid an amount
equal to twelve months of base salary plus bonus  compensation  and continuation
of his employee  benefits for one year in the event Mr.  Condo's  employment  is
terminated or he is removed from his position as Chief Executive  Officer within
six months following certain "change of control" events relating to the Company.
Such arrangement was approved by the full Board of Directors.

The offer of employment  letter dated  September 7, 1995 for James H.  Buchanan,
Chief Financial Officer, Secretary and Treasurer of the Company, stipulates that
Mr.  Buchanan  will be paid an amount  equal to twelve  months of base salary in
semi-monthly  installments  should his  employment  be terminated by the Company

(8)   RESTRUCTURING COSTS

The Company  reorganized  its sales force and made other  changes to its overall
organization  in April  1997.  In  connection  with these  changes,  the Company
reduced its workforce by approximately  10% and recorded a restructuring  charge
of  $577,000  in the first  quarter of fiscal  year 1998.  The charge  primarily
consisted of severance pay and medical and other severance benefits for nineteen
terminated  employees  in  sales,  development,   marketing  and  administrative
functions. All payments associated with the restructuring charge were paid prior
to the end of fiscal year 1998.

e) The Company paid legal fees and expenses totaling  approximately  $221,000 in
fiscal  year 1997 to a law firm in which a former  director of the Company was a
partner. No such fees were paid in fiscal years 1999 and 1998.


(11)  RECENTLY ISSUED ACCOUNTING PRONOUNCEMENTS

The Company adopted  Statement of Financial  Accounting  Standards  ("SFAS") No.
130, "Reporting  Comprehensive Income," during the first quarter of fiscal 1999.
SFAS 130 requires  additional  disclosures  with  respect to certain  changes in
assets and  liabilities  that  previously  were not  required  to be reported as
results of operations for the period.

In 1998, the Company  adopted  Statement of Financial  Accounting  Standards No.
131,  "Disclosures about Segments of an Enterprise and Related Information." FAS
131  supercedes  FAS  14,  "Financial  Reporting  for  Segments  of  a  Business
Enterprise",  replacing the "industry  segment"  approach with the  "management"
approach.  The management approach designates the internal  organization that is
used by management for making operating  decisions and assessing  performance as
the  source  of  the  Company's  reportable  segments.  FAS  131  also  requires
disclosures  about products and services,  geographic areas and major customers.
The  adoption  of FAS 131 did not affect  results  of  operations  or  financial
position  but did affect the  disclosures  of segment  information.  The Company
accounts for all operations as one segment.

In June 1998, the Financial  Accounting Standards Board ("FASB") issued SFAS No.
133, "Accounting for Derivative  Instruments and Hedging Activities," which will
be effective  for the Company's  fiscal year 2001.  This  statement  establishes
accounting and reporting standards  requiring that every derivative  instrument,
including  certain  derivative  instruments  embedded  in  other  contracts,  be
recorded in the balance  sheet as either an asset or  liability  measured at its
fair value.  The statement also requires that changes in the  derivative's  fair
value be recognized in earnings  unless specific hedge  accounting  criteria are
met. The Company  believes the adoption of SFAS No. 133 will not have a material
effect on the financial statements.

The American  Institute of Certified Public  Accountants has issued Statement of
Position 98-9,  "Modification of SOP-97-2,  Software Revenue  Recognition,  With
Respect to Certain Transactions." SOP 98-9 is effective for revenue transactions
entered into in the  Company's  fiscal year 2001.  The Company has evaluated SOP
98-9 and does not  believe  its  adoption  will  have a  material  effect on the
financial statements.

To Excalibur Technologies Corporation:

    We have audited in accordance with generally  accepted  auditing  standards,
the  consolidated  balance  sheet of Excalibur  Technologies  Corporation  as of
January  31,  1998  and  the  related  consolidated  statements  of  operations,
shareholders'  equity  and cash  flows for each of the two  years in the  period
ended  January  31,  1998  included in this Form 10-K and have issued our report
thereon dated  February 27, 1998.  Our audit was made for the purpose of forming
an opinion on the basic  financial  statements  taken as a whole.  The  schedule
listed in the index is the  responsibility  of the Company's  management  and is
presented  for  purposes  of  complying   with  the   Securities   and  Exchange
Commission's  rules  and is not part of the  basic  financial  statements.  This

the  basic  financial  statements  and,  in our  opinion,  fairly  states in all
material  respects  the  financial  data  required  to be set forth  therein  in
relation to the basic financial statements taken as a whole.

                             INTRODUCTORY PROVISIONS

      Section 1.1.      General Definitions.

      As used herein, the term:

      (a) "Building"  means the referenced  tower of a two-building  multi-story
office and retail project  located in Fairfax  County,  Virginia.  The "Project"
consists of two office/retail  towers and a multi-level  parking facility,  plus
surface parking.  The Project is known as "Tysons  International  Plaza," and is
located at 1919 and 1921 Gallows  Road,  Vienna,  Virginia  22182 (Tower I being
located at 1919 Gallows Road and Tower II being located at 1921 Gallows Road); a
legal  description  of the  Project  site is attached  hereto as  Schedule  A-1.
Landlord  represents  and  warrants  that the estates and  improvements  therein
comprising the Building and the Project are owned by the Landlord in fee simple.
The  Landlord's  fee simple  estate is subject  to a Mortgage  securing  debt to
Teachers Insurance and Annuity Association of America.

      (b)  "Common  Areas"  means  those  areas  and  facilities  which  may  be
furnished, from time to time, by Landlord at the Building, for the non-exclusive
general or limited common use of Landlord, Tenant, other tenants, subtenants and
other occupants of the Project, their officers,  agents,  employees,  customers,
suppliers and materialmen,  and those areas and facilities used for maintenance,
management and marketing of the Project, and all loading docks, ramps and areas,
delivery passages, freight elevators,  service corridors,  sidewalks,  walkways,
roadways,  alleyways,  parking  areas,  courts,  courtyards,  ramps,  fountains,
retaining walls, stairways, escalators, elevators, fire corridors, fire escapes,
park areas,  first-aid  stations,  maintenance and mechanical areas, rest rooms,

      (c) "Default Rate" means an annual rate of interest equal to the lesser of
(i) the maximum rate of interest  for which Tenant may lawfully  contract in the
Commonwealth of Virginia from time to time, or (ii) twenty percent (20%).

      (d) "GRA"  means with  respect to the area being  measured,  the number of
square  feet of  rentable  area for the  exclusive  use by a tenant for  general
office  purposes.  Said area shall be measured in  accordance  with the modified
BOMA method of measurement. From time to time during the Term, Landlord may give
Tenant  notice of the total GRA in the Building and in the Project,  as such GRA
may be revised  because of  additions  to (or  subtractions  from) the  Building
and/or  the Common  Areas  and/or the  Project,  or as such GRA may be  adjusted
pursuant to provisions  in the leases of other tenants or occupants.  The GRA in
the  Premises  and in all other areas set aside for tenants  within the Building
shall  be  utilized  to  calculate  the  GRA  Fraction  and to  make  any  other
calculations  required  to  determine  Tenant's  proportionate  share of certain
charges set forth in this Lease.

<PAGE>

      (e) "GRA Fraction"  means a fraction,  the numerator of which shall be the
GRA in the Premises  and the  denominator  of which shall be the average  annual
aggregate of the total square  footage in the Project which is leased to tenants
from time to time, which  denominator shall in no event be less than that number
which is 95% of the total GRA in the Project.

      (f) "GRA Tax Fraction"  means a fraction,  the numerator of which shall be
the GRA in the Premises and the  denominator  of which shall be the total GRA in
the Project.

      (g) "Landlord's  Management Agent" means the person or persons  designated
by Landlord from time to time to lease,  manage,  operate,  and/or supervise the
operations of the Building for and on behalf of Landlord.

      (h) "Premises"  means that portion of the Building as shown on Schedule A,
having  the  square  footage  of  floor  area  specified  in  clause  (c) of the
Fundamental Lease Provisions. The Premises shall consist of the Premises Portion
#1, the Premises Portion #2 and the Premises Portion #3.

      Section 1.2.      Table of Defined Terms.

      The Section  reference for definitions of all other capitalized terms used
in this Lease are contained in the Table of Defined Terms immediately  following
the Table of Contents.

      Section 1.3.      Changes to Project.

      As between Landlord and Tenant,  Landlord may at any time and from time to
time eliminate or add any improvements,  or change or consent to a change in the
shape,  size,  location,  number,  height or extent of the  improvements  to any
portion of the Building and/or the Project.  Nothing herein contained,  however,
shall be deemed to permit  Landlord to change the  dimensions or location of the
Premises or  materially  adversely  affect the access to the  Premises  from the
Common  Areas  adjacent  thereto,  if any, or  materially  adversely  affect the
appearance or occupancy by Tenant of the  Premises,  without  Tenant's  consent,
unless any such changes are  required by reason of any  federal,  state or local
environmental  or other law, rule,  regulation,  guideline,  judgment,  order or
action.

to at least three (3) general contractor bidders. Each of the general contractor
bidders shall submit a fixed price bid including  the  subcontractor  or "trade"
work, bid by the general contractor to at least three (3) subcontractor bidders.
The  selection  of the  General  Contractor  shall  be made by  Landlord  in its
commercial good faith.

                  (ii) Landlord or its  affiliate,  at no cost to Tenant,  shall
administer,  supervise and manage the  refurbishments  and  improvements  to the
Premises pursuant to this Section 2.2.

                  (iii)  Tenant has  designated  Ms.  Nancy  McKinley  to be its
construction coordinator who shall be entitled to inspect the refurbishments and
improvements  and  otherwise act on Tenant's  behalf during such time.  Tenant's
construction  coordinator  shall have full  authority  to make all  decisions on
behalf of Tenant with  respect to material or design  changes and change  orders
(to  be  documented,   submitted  to  and  executed  by  the  parties  prior  to
commencement  of such work),  and any decisions made in the field by such person
shall be binding upon Tenant. Landlord agrees that it shall cooperate, and shall
cause the General Contractor and Landlord's  construction  manager to cooperate,
with Tenant's construction coordinator. Landlord agrees that it shall not effect
change orders  without the written  approval of Tenant or Tenant's  construction
coordinator.

                  (iv) The improvements to the Premises  contemplated in Section
2.2(a) hereof shall be performed by Landlord upon  forty-five (45) days' written

      Section 2.3.      Allowance

            (a)  Tenant  shall  receive a total  improvement  and  refurbishment
allowance  (the   "Allowance")   which  shall  be  applied   towards   leasehold
improvements and refurbishments as set forth in Section 2.2 (including  signage,
as set forth in Section 5.4 (c) hereof); the Allowance shall be in the total sum
of Fifty-Two Thousand Dollars ($52,000.00).

            (b) The cost of the leasehold  improvements and refurbishments shall
be paid monthly by Landlord out of the  Allowance  based upon the draw  schedule
and work in place. Tenant and Tenant's construction  coordinator shall receive a
copy of each  monthly  requisition.  It is hereby  agreed  that all  permanently
affixed leasehold improvements, if any, shall immediately become the property of
Landlord upon completion unless otherwise agreed to in writing.

            (c) In the event the total cost of the  leasehold  improvements  and
refurbishments is less than the Allowance,  Landlord shall retain such amount as
its  property  and there shall be no payment to Tenant or abatement of Rent with
respect thereto.

            (d) In the event the total cost of completing the  improvements  and
refurbishments  to the Premises shall exceed the Allowance (the "Excess Costs"),
said Excess Costs shall be paid by Tenant to Landlord in cash,  in full,  within
thirty (30) days after Landlord's demand therefor;  provided,  however,  that at
Tenant's  election such Excess Costs (but not to exceed Two Dollars  [$2.00] per
square foot of GRA in the  Premises)  may be amortized as  additional  Base Rent
over the Main Term, calculated using an interest factor of twelve percent (12%).
Attached  hereto as  Schedule I is a copy of bills  received  by  Landlord  with
respect to the performance of the initial improvements to the Premises.

            (e) Landlord  represents  and warrants that,  upon the  Commencement
Date and completion of the improvements and refurbishments to the Premises to be
performed by Landlord pursuant to Section 2.2 hereof, the Premises are and shall
be in compliance with all requirements of the Americans with Disabilities Act of
1990 (the  "ADA").  Upon  completion  of the  improvements  and  refurbishments,
Landlord  shall be  responsible  for ADA  compliance  issues with respect to the
Common  Areas and Tenant  shall be  responsible  for all ADA  compliance  issues
within the Premises.

      Section 2.7.      Mechanics' and Other Liens.

      (a)  With  respect  to any work  performed  by  Tenant  in  furnishing  or
equipping the Premises hereunder,  and with respect to any alterations performed
pursuant  to  Section  9.4,  Tenant  will not  permit to be  created  and has no
authority  to  permit  to  be  created  or  to  remain  undischarged  any  lien,
encumbrance  or charge  (arising  out of any work done or  materials or supplies
furnished by an contractor, subcontractor,  mechanic, laborer or materialman, or
any mortgage,  security agreement or otherwise by or for Tenant), which might be
or  become a lien or  encumbrance  or  charge  upon the  Premises,  or  Tenant's
leasehold estate therein,  the Project or any income therefrom.  Tenant will not
suffer any other  matter or thing  whereby the estate,  rights and  interests of
Landlord in the Project might be encumbered or impaired.

      (b) If any  mechanics'  lien on account of any alleged debt of Tenant,  or
any person acting on Tenant's behalf,  shall be filed against the Premises,  the
Project or any income  therefrom,  Tenant  shall take and  diligently  prosecute
appropriate  action to have the same discharged or bonded and released of record
at Tenant's  sole  expense  within  thirty (30) days of the filing of such lien.
Upon  Tenant's  failure so to do,  Landlord,  in  addition to any other right or
remedy that it may have, may cause said lien to be discharged or bonded and take
such other action as may be reasonably  necessary to protect its  interest,  and
Tenant  shall pay any amounts paid by Landlord in  connection  with such action,
and all  reasonable  legal and other costs and expenses  incurred by Landlord in
connection  therewith  (including  reasonable  attorneys'  fees, court costs (if
awarded post-judgment) and other necessary disbursements). Any such amounts paid
by Landlord and the amount of any such  expenses or costs  incurred by Landlord,
if not paid by Tenant to Landlord  within thirty (30) days after the date Tenant
receives  written  notice  from  Landlord  of the amount  thereof and demand for
payment of the same,  shall,  together with interest thereon at the Default Rate
from the date of the receipt by Tenant of the  aforesaid  written  notice to the
date of payment thereof by Tenant,  be treated as Additional  Rent, and shall be
payable by Tenant to  Landlord  not later than thirty (30) days after the giving
of such written  notice and demand.  Nothing  herein  contained  shall  obligate
Tenant to pay or discharge any lien created by Landlord.

      (c) Except with respect to the initial  improvements and refurbishments to
the Premises to be performed by Landlord pursuant to Section 2.2 hereof,  Tenant
shall promptly pay all persons furnishing labor or materials with respect to any
work  performed by or on behalf of Tenant in, on or about the Premises.  No work
which Landlord permits Tenant to perform shall be deemed to be for the immediate
use and benefit of Landlord so that no mechanics' or other lien shall be allowed
against the estate of  Landlord  by reason of any  consent  given by Landlord to
Tenant to improve the Premises.  This Lease expressly provides that the interest
of Landlord shall not be subject to liens for improvements made for or on behalf
of Tenant, and Tenant shall notify each of Tenant's contractors of the foregoing
provisions.

      (d) To the extent permitted by law,  Landlord shall have the right to post
such other notices as Landlord may deem to be appropriate  for the protection of
its  interests in the Premises.  The  provisions of this Section 2.7 shall apply
with respect to any work performed by or on behalf of Tenant in, on or about the
Premises during the Term thereof.

      Section 2.8.      Tenant's Property.

      (a) All trade  fixtures,  furniture and equipment (as  distinguished  from
leasehold improvements) owned by Tenant and installed in the Premises ("Tenant's
Property")  shall be and remain the property of Tenant and shall be removable at
any time,  including upon the expiration of the Term,  provided (i) Tenant shall
not at such time be in default of any term,  covenant or provision of this Lease
beyond any applicable grace, notice or cure period, and (ii) Tenant shall repair
to the satisfaction of Landlord any damage to the Premises caused by the removal
of any of Tenant's Property.

      (b) If Tenant's Property,  or any portion thereof, is not removed from the
Premises  upon the  expiration  of the Term or any earlier  termination  of this
Lease in accordance with the foregoing,  such remaining Tenant's Property shall,
at the election of  Landlord,  become the  personal  property of  Landlord,  and
Tenant's  rights  therein  shall  cease upon the  exercise  of such  election by
Landlord.

Main Term.


      Section 3.2.      Preliminary Term.

      (a) "Main Term" means the period  commencing on the Commencement Date and,

commencing on the Commencement Date, as defined in Section 4.2.

other charges for which Tenant is responsible  are to be based upon the calendar
year or partial calendar year, whichever is applicable.

      Section 3.4.      Termination.

      Unless sooner  terminated  pursuant to the provisions  hereof,  this Lease
shall  terminate  on the  expiration  of the Term  without the  necessity of any
notice from either  Landlord or Tenant to terminate the same,  and Tenant hereby
waives notice to vacate or quit the Premises and agrees that  Landlord  shall be

<PAGE>

entitled to the benefit of all remedies at law or equity  respecting the summary
recovery of possession  of the Premises from a Tenant  holding over, to the same
extent as if statutory notice had been given. For a period of twelve (12) months
prior to the  expiration of the Term,  Landlord shall have the right to show the
Premises and all parts thereof,  upon  reasonable  advance notice to Tenant,  to
prospective tenants during normal business hours.

      Section 3.5.      Holding Over.

      If Tenant shall be in possession of the Premises after the  termination of
this Lease,  in the absence of any written  agreement  extending  the Term,  the
tenancy  under this Lease shall become one from  month-to-month,  terminable  by
Landlord on thirty (30) days' prior written notice, at a monthly rental equal to
(i) one hundred fifty percent  (150%) of the sum of the monthly  installment  of
Base Rent payable during the last calendar month of the Term, plus (ii) Tenant's
Operating  Charge and Tenant's Taxes as otherwise  calculated  hereunder for any
such month.  Tenant shall also pay as Additional  Rent all other charges payable
under the terms of this  Lease,  prorated  for each month  during  which  Tenant
remains in possession. Such month-to-month tenancy shall be subject to all other
conditions, provisions and obligations of this Lease. Tenant shall not interpose
any counterclaims in a summary proceeding or other action based on holdover.  At
any time after a termination under this Section becomes effective,  Landlord may
reenter and take  possession of the  Premises,  any rule of law or equity to the
contrary notwithstanding.

      Tenant hereby agrees to pay to Landlord  during the Term, at the times and
in the manner herein provided, Base Rent, as may be increased from time to time,
and Additional  Rent  (collectively,  "Rent").  Tenant's  obligation to pay Rent
during the Term shall survive the termination of this Lease.

      Section 4.2.      Commencement Date.

      "Commencement  Date"  means (i)  October  6,  1999,  with  respect  to the

respect to the Premises Portion #3.

      Section 4.3.      Base Rent.

      For the first Lease Year during the Term,  Tenant  shall pay  Landlord the
annual  Base  Rent  amount  set  forth in clause  (g) of the  Fundamental  Lease
Provisions  ("Base  Rent"),  which shall be payable in twelve (12) equal monthly
installments,  in  advance,  on the  first  (1st)  day of  each  calendar  month
(provided,  however,  that Base Rent with respect to the Premises Portion #1 and
Premises  Portion #2 for the partial month  commencing on October 6, 1999, shall
be due and payable on or before October 6, 1999).

<PAGE>

      Section 4.4.      Annual Rent Increase.

      For each Lease Year during the Term after the first Lease Year, the annual
Base Rent shall be that amount which is the sum equaling the product obtained by
multiplying  the Base Rent for the  immediately  preceding Lease Year by 103%. A
schedule of the Base Rent  increases  is found at clause (g) of the  Fundamental
Lease Provisions. With respect to the Premises Portion #3, the first annual Base
Rent increase shall be effective on October 6, 2000, i.e. the first  anniversary
of the  Commencement  Date  with  respect  to the  Premises  Portion  #1 and the
Premises  Portion  #2; to the end that the Base Rent rate shall be the same with
respect to the entire Premises at all times during the Term of the Lease.

      Section 4.5.      Additional Rent.

      In  addition  to Base  Rent,  Tenant  shall pay all other sums of money or
charges of whatever nature required to be paid by Tenant to Landlord pursuant to
this  Lease  (collectively,  "Additional  Rent"),  whether  or not the  same are
designated as Additional  Rent. Any Additional Rent accruing under any provision
of this Lease shall,  except as is otherwise set forth in this Lease, be due and
payable  in the  installment  of the Base Rent the next  falling  due after such
Additional  Rent  accrues  becomes due and payable,  unless the  Landlord  makes
written demand upon the Tenant for payment thereof at any earlier time, in which
event such Additional Rent shall be due and payable at such time.

      Section 4.6.      Payment of Rent.

      Except as otherwise  provided  herein,  Tenant shall pay all Rent when due
and payable,  without any set-off,  deduction,  notice or prior demand  therefor
whatsoever.  If Tenant shall fail to pay any Rent within ten (10)  business days
after the same is due,  Tenant shall be  obligated to pay a late payment  charge
equal to the greater of (a) One  Hundred  Dollars  ($100.00)  or (b) ten percent
(10%) of any Rent  payment  not paid when due,  to  reimburse  Landlord  for its
additional administrative costs. Rent and any reports and statements required of
Tenant  shall be paid and  delivered  to Landlord at the  designated  management
office in the  Project  between  the hours of 8:00 a.m.  and 6:00  p.m.,  Monday
through Friday (except  holidays),  or at such other place as Landlord may, from
time to time,  designate  in a notice  to  Tenant.  Any  payment  by  Tenant  or
acceptance  by Landlord of a lesser amount than shall be due shall be treated as
a payment on account.  The acceptance by Landlord of a check for a lesser amount
with an endorsement  thereon,  or upon any letter  accompanying such check, that
such lesser amount is payment in full shall be given no effect, and Landlord may
accept  such check  without  prejudice  to any other  rights or  remedies  which
Landlord may have against Tenant.

      Section 4.7.  Interest Charge.

      In addition to any late payment  charge which might  otherwise be due, any
Rent  payable  by Tenant  under  this Lease that is not paid when due shall bear
interest  at the Default  Rate from the first day due until such Rent,  plus all
interest accrued thereon, are paid in full.

<PAGE>

      Section 4.8.  Security Deposit.

      As a security deposit ("Security  Deposit"),  Tenant, at Tenant's expense,
and on or before the Commencement  Date with respect to the Premises Portion #3,
shall deliver to and deposit with Landlord an irrevocable  unconditional  letter
of credit (the "Letter of Credit")  drawn on  NationsBank  and  redeemable  upon
presentation at a location in New York City,  naming Landlord as the beneficiary
thereof and otherwise in form and substance  reasonably  acceptable to Landlord,
to be held as security for the payment of any Rent (including  Additional  Rent)
payable by Tenant and for the faithful  performance  of all  covenants of Tenant
hereunder.  The original  principal  amount of the Letter of Credit shall be One
Hundred Seventy-Eight Thousand Dollars  ($178,000.00),  and the Letter of Credit
shall remain issued and  outstanding  throughout  the Term;  provided,  however,
that,  absent an Event of Default by Tenant which remains  outstanding after any
applicable  notice,  grace or cure period, the principal amount of the Letter of
Credit may be reduced at the  beginning of each of the second,  third and fourth
Lease  Years with  respect to Premises  Portion #3 by an amount  equal to twenty
percent (20%) of the initial principal amount (i.e., $35,600.00).  The Letter of
Credit  shall  provide  Landlord  with not less than thirty (30) days' notice of
expiration,  cancellation,  renewal or non-renewal thereof. Tenant shall deliver
to Landlord  evidence of any renewal thereof within ten (10) business days prior
to the expiration thereof; a failure of Tenant to obtain a renewal of the Letter
of Credit or post satisfactory  substitute collateral hereunder shall constitute
an Event of Default hereunder.  Upon the occurrence of an Event of Default,  the
Security Deposit may, at Landlord's option, be applied on account of the default
up to the amount  reasonably  needed to cure such an Event of Default.  Landlord
shall deliver the Letter of Credit to any  purchaser of  Landlord's  interest in
the Premises, in the event that such interest be sold; and, thereafter, Landlord
shall be discharged from any further liability with respect thereto,  and Tenant
agrees to look solely to such purchaser for the return of the Security Deposit.

thereafter shall continuously  occupy and use the Premises for the permitted use
as set forth in clause (i) of the Fundamental Lease Provisions ("Permitted Use")
and for no other  purpose  whatsoever  without  the  prior  written  consent  of
Landlord.  If Tenant abandons any portion of the Premises at any time during the
Term,  then  Landlord  shall be entitled (but not  obligated) to terminate  this
Lease;  provided,  that if Tenant is not  otherwise in default  hereunder,  then
Landlord shall not be entitled to accelerate  Rent or collect any damages beyond
the date of termination.

Premises,  whether  structural or otherwise,  unless such  obligation  hereunder
arises as a result of the use or occupancy thereof by Tenant for any purpose not
authorized as a Permitted Use herein or the conduct by Tenant of its business in
the Premises in a manner  different from the ordinary and proper conduct of such
business.

      (c) In regard to the use and  occupancy  of the  Premises  and the  Common

                                      TAXES

      Section 6.1.  Real Estate Taxes.

      (a) Beginning  January 1, 2000,  and continuing  thereafter,  Tenant shall
pay, as Additional Rent,  Tenant's  proportionate share of the increases for the
remainder  of the Term in all Taxes over those  Taxes paid by  Landlord  for the
Project with respect to calendar  year 1999 (the "Base  Year").  As used herein,
"Taxes" shall mean amounts payable by Landlord with respect to personal property
taxes  (excluding  any personal  property taxes of the Landlord for equipment or
items not used  directly  in the  operation  or  maintenance  of the  Building),
intangible  taxes,  real estate  taxes,  ad valorem  taxes,  general and special
assessments,  taxes on real estate rental  receipts,  taxes on Landlord's  gross
receipts,  or any other Tax imposed  upon or levied  against real estate or upon
owners of real estate rather than persons generally,  payable with respect to or
allocable to the Project (including, but not limited to, any payments in lieu of
any Taxes,  and fees of attorneys,  consultants and appraisers in contesting any
Taxes).

      (b) The amount of Tenant's  proportionate  share of the  increase in Taxes
over  the  Base  Year  (which  proportionate  share of the  increase  is  called
"Tenant's Taxes") shall be computed by multiplying the amount of the increase in
such Taxes over those  Taxes paid or  incurred  for the Base Year by the GRA Tax
Fraction. In the last Lease Year of the Term, the provisions of this Section 6.1
shall apply, but Tenant's liability for its proportionate  share of the increase
in Taxes for such year shall be subject to a pro rata adjustment  based upon the
number of days of such Lease Year falling  within the calendar year in question.
Tenant expressly agrees that Tenant shall have no right to appear or contest any
Taxes  assessed,  allocated  or imposed  with  respect to the Project and Tenant
hereby expressly waives any and all rights now or hereafter conferred upon it by
law to independently contest any Taxes.

      (c) Taxes shall not  include:  (i) federal,  state or local income  taxes;
(ii)  franchise,   gift,  transfer,   capital  stock,  estate,   succession,  or

<PAGE>

inheritance  taxes;  (iii)  penalties or interest for late payment of Taxes;  or
(iv) any  increases in Taxes which result solely from the creation of additional
rentable  area  in the  Project  or in the  Building  or  from  improvements  or
alterations  made by Landlord or other  tenants.  Any  increase in Taxes for the
Building, land or Project resulting from a refinancing or sale shall be added to
the Base Year.

      (d) If the Taxes are phased in during the Lease  Term for any  reason,  or
should the Taxes be abated or reduced,  for any reason,  for the Base Year, then
the Taxes for the Base Year shall be adjusted  so that they are  computed on the
same tax basis as those Taxes for Lease Years in which the  phase-in,  abatement
or reduction did not occur. In addition,  if Landlord  receives a tax refund for
any Lease Year or partial Lease Year during the Term,  Landlord shall deliver to
Tenant its pro rata share of any such refund.

      Section 6.2.  Payment of Tenant's Taxes.

      (a)  Tenant's  Taxes shall be paid by Tenant in twelve (12) equal  monthly
installments  in advance in such  amounts as are  estimated  and billed for each
applicable  Lease Year by  Landlord,  each such  installment  being due with the
monthly installment of Base Rent.

      (b) Within  sixty (60) days  after the date upon which  Landlord  shall be
obligated  to  pay  any  Tax  or  Taxes,   or  such  reasonable  (in  Landlord's
determination)  time thereafter,  Landlord shall certify to Tenant the amount of
Taxes  allocated  and  assessed  for the  period in  question  and the amount of
Tenant's  proportionate  share thereof.  The proportionate share paid or payable
for each such period shall be adjusted between Landlord and Tenant,  the parties
hereby  agreeing  that Tenant  shall pay  Landlord or Landlord  shall  credit to
Tenant's account,  or (if such adjustment is at the end of the Term) pay Tenant,
as the  case  may be,  within  thirty  (30)  days of  Tenant's  receipt  of such
certification, such amounts as may be necessary to effect such adjustment to the
agreed  upon  proportionate  share.  The  failure of  Landlord  to provide  such
certification  within the time prescribed  above shall not relieve Tenant of its
obligations  generally or for the specific  Lease Year in which any such failure
occurs.

      Section 6.3.      Taxes on Rent and Other Taxes.

      In addition to Tenant's  Taxes,  Tenant shall pay to Landlord (if Landlord
is  required by law to collect,  or has any  liability  for the payment of, such
taxes) any  excise or other tax which may in the  future be  levied,  imposed or
assessed by any  governmental  authority or other taxing authority upon any Rent
payable hereunder  (collectively,  "Rental Tax"); provided,  that if such Rental
Tax is assessed in lieu of the Taxes, than the amount of Taxes paid for the Base
Year shall be deducted  from the total  Rental Tax prior to the  calculation  of
Tenant's  proportionate  share  thereof.  Tenant  shall pay such  Rental  Tax to
Landlord  with  each  payment  of Rent  (including  payments  of Base  Rent  and
Additional Rent). Tenant shall also pay, prior to the time the same shall become
delinquent  or payable with  penalty,  all personal  property  taxes  imposed on
Tenant's  furniture,   trade  fixtures,   apparatus,   equipment  and  leasehold
improvements  installed by Tenant or by Landlord on behalf of Tenant  (except to
the extent such leasehold  improvements shall be covered by Taxes referred to in
Section 6.1 hereof), and except as otherwise  specifically  provided for herein,
and any other property of Tenant.  Landlord may require that Tenant's  leasehold
improvements be separately assessed by the taxing authority.

all portions of the Common Areas; and (vi) to do and perform such other acts in,

category shall include the actual cost of real estate taxes separately billed to

            (xiii)  Expenses  resulting  from the  negligent or tortious acts of

            (xiv) Any other  cost or expense  which,  under  generally  accepted
accounting  principles  consistently  applied,  would not be considered to be an
Operating Cost of the Project.

      Section 7.3.      Tenant's Operating Costs Charge.

      (a) (i)  Beginning  January 1, 2000,  and  continuing  thereafter  for the
remainder  of the Term,  Tenant  shall pay to Landlord,  as  Additional  Rent, a
proportionate  share of the  increases to Operating  Costs over those  Operating
Costs incurred by Landlord for the Project during the Base Year,  which share of
such  increases  ("Tenant's  Operating  Costs  Charge")  shall  be  computed  by
multiplying  the  increases in Operating  Costs for the period in question  over
those Operating Costs incurred for the Base Year by the GRA Fraction.

<PAGE>

            (ii)  Tenant's  Operating  Costs  Charge  shall be paid by Tenant in
monthly  installments  in such amounts as are  estimated and billed by Landlord,
each installment being due with the monthly Base Rent installment.

      (b) If at any time  during  the  Lease  Term,  less  than 95% of the total
rentable area of the Project is leased by tenants,  or Landlord is not supplying
services to 95% of the total rentable area of the Project at any time during any
calendar  year,  the Operating  Costs for such calendar year shall be reasonably
determined to be an amount equal to the expenses that would normally be expected
to be incurred had such  occupancy  been 95% of the total  rentable  area of the
Project and had Landlord been  supplying  services to 95% of the total  rentable
area of the Project  throughout the calendar year. The only costs which shall be
adjusted in this manner shall be variable  expenses where the amount is directly
related to the level of  occupancy  or square foot area  receiving a  particular
service.  Landlord will indicate  which expenses were adjusted in this manner in
the Operating Costs statement.

      (c) If a new  category  of expense is  incurred  after the Base Year,  the
first full year's  expense for such item shall be added to the  Operating  Costs
for the Base  Year,  commencing  with the  first  full  calendar  year that such
expense is  incurred,  so that Tenant  shall only be required to pay  subsequent
increases in such expense.

      (d) Within one hundred  twenty (120) days (or such  additional  time as is
reasonable  under the  circumstances)  after the end of each  such  Lease  Year,
Landlord shall deliver to Tenant an itemized statement broken down in categories
with reasonable  detail of the Operating Costs for such period,  and the monthly
installments paid or payable shall be adjusted between Landlord and Tenant,  the
parties hereby  agreeing that Tenant shall pay Landlord or Landlord shall credit
Tenant's  account (or if such  adjustment is at the end of the Term, pay Tenant,
as the case may be), within thirty (30) days of receipt of such statement,  such
amounts as may be necessary  to effect  adjustment  to the agreed  proportionate
share for such Lease Year.  The failure of  Landlord to provide  such  statement
within the time  prescribed  above shall not relieve  Tenant of its  obligations
generally or for such period in which any such failure occurs.

      (e) The Operating  Costs and the books and records of Landlord for a Lease
Year,  including  those for the Base Year, may be audited by Tenant's  certified
public accountant or other authorized  representative,  at Landlord's designated
management  office during normal  business  hours,  upon at least ten (10) days'
prior notice to Landlord,  at any time during the Lease Year following the Lease
Year that is the subject of such audit.

      (f)  If  Tenant  challenges  Landlord's  computations  of  the  Base  Year
Operating  Costs,  the amount of  Operating  Costs or Taxes,  Tenant  shall give
Landlord  notice  stating  Tenant's  objections.  If Tenant's audit of Operating
Costs or Taxes for the Base Year or any  subsequent  year  indicates that Tenant
was  overcharged  for the same and  Landlord  is in  agreement,  Landlord  shall
promptly, but within thirty (30) days, repay all such overpayments to Tenant and
adjust  Tenant's  Base Year, if  necessary.  If Tenant's  audit of the Operating
Costs  for the Base  Year or any  subsequent  year  indicates  that  Tenant  was
overcharged for the Operating Costs or Taxes, by an amount which is greater than
or equal to five  percent  (5%) of the  amount  which  should  have been paid by
Tenant,  Landlord shall promptly reimburse Tenant for all of Tenant's actual and
reasonable costs associated with the audit.

      Section 7.4.      Parking.

      (a) Tenant  acknowledges  that it has been  advised by  Landlord  that the
Building  includes a multi-level  parking garage operated by a third party other
than Landlord (the "Parking Garage").

      (b) During the Main Term, Landlord shall cause the Parking Garage operator
to provide to Tenant, at the then-prevailing  market rate specified from time to
time by the Parking  Garage  operator  (and  verified  in  writing,  at Tenant's
expense,  by an  independent  third-party  mutually  acceptable  to Landlord and
Tenant),  parking  spaces  based on the  parking  ratio of 3.5  spaces per 1,000
rentable square feet of the Premises (i.e., sixty-five (65) spaces). The current
market rate charged by the parking garage operator is Fifty Dollars ($50.00) per
space per month.  The parking  spaces shall be located within the Parking Garage
for Tenant's non-exclusive use. Parking spaces shall be available and accessible
to Tenant for Tenant's use  twenty-four  (24) hours per day,  seven (7) days per
week.

      (c) Landlord hereby reserves the right,  but shall have no obligation,  to
establish  a  parking  validation  system  for the  Project  pursuant  to  which
customers  and patrons of all  tenants in the Project  shall be entitled to park
within  the  Parking  Garage at  reduced  rates,  provided  that  they  obtain a
validation  stamp from one or more of the  tenants  within the  Project.  In the
event that Landlord shall  establish such a parking  validation  system,  Tenant
hereby agrees to  participate  in such Parking  Validation  System in accordance
with the rules and regulations  established by Landlord,  and to pay to Landlord
its  proportionate  share of the costs and  expenses  thereof,  which  costs and
expenses shall be included in Operating Costs.

      Section 7.5.      Overtime HVAC.

      Landlord  shall provide HVAC services to the Premises  during the hours of
8:00 a.m. through 6:00 p.m.,  Monday through Friday,  and 8:00 a.m. through 1:00
p.m. on Saturdays,  legal holidays excepted.  Landlord will use its commercially
reasonable  efforts to provide  such  services  within  the  reasonable  maximum
allowable temperatures  commensurate with first class office space in the Tysons
Corner,  Virginia area. Landlord shall, at Tenant's request and expense, upon 24
hours'  notice,  furnish HVAC  services to the Premises  during hours other than
those stated above.

      Section 8.1.  Environmental Covenants.

      In its use of the Premises and the remainder of the Building,  the Project
and the land,  Tenant  shall not (either  with or without  negligence)  cause or
permit the escape,  disposal or release of any biologically or chemically active
or other hazardous substances or materials,  or allow the storage or use of such
substances or materials in any manner, or allow any such materials or substances

      If any lender or  governmental  agency ever requires  testing to ascertain
whether or not there has been any release of hazardous materials on the Premises
while  this  Lease  is in  effect,  then  Tenant's  proportional  share  of  the
reasonable  costs  thereof  shall be  reimbursed  by the Tenant to Landlord upon
demand as additional charges if such requirement applies to the Premises. Tenant
shall  execute  affidavits,  representations  and the like  from time to time at
Landlord's request  concerning  Tenant's best knowledge and belief regarding the
presence of hazardous  substances  or materials  on the  Premises.  Tenant shall
defend,  indemnify and hold harmless  Landlord  against and from any  liability,
claim of liability or expense arising out of any release of hazardous substances
or materials on the Premises occurring while Tenant is in possession thereof, or
elsewhere if caused by Tenant or any person acting under Tenant.

      Section 8.4.      Pre-existing Conditions.

      Notwithstanding  anything  contained herein to the contrary,  Tenant shall
not be liable, and shall have no obligation to indemnify Landlord,  with respect
to the  environmental  conditions of the Premises  existing at the  Commencement
Date, and Tenant shall not be liable or responsible  for escalation or Operating
Costs  or  direct   reimbursement   obligations  for  remediation  of  any  such
pre-existing conditions.

(excluding,  however,  all doors,  door frames,  sliding doors,  windows and any
glass therein);  provided (i) Tenant shall give Landlord notice of the necessity
for such repairs, and (ii) the necessity for such repairs shall not have arisen,
in whole or in part, from the negligence or willful acts or omissions of Tenant,
its  agents,  concessionaires,   officers,  employees,  licensees,  invitees  or
contractors.

      Section 9.2.      Tenant's Duty to Maintain Premises.


<PAGE>

      (a) Tenant  shall,  at all times from and after  delivery of possession of
the Premises to Tenant,  at its own cost and  expense,  maintain the Premises in
good and tenantable condition, and Tenant shall make all repairs to the Premises
or  any   installations,   equipment  or  facilities  therein  (except  for  any
maintenance and repairs required to be made by Landlord  pursuant to Section 9.1
or  reconstruction  required to be made by Landlord  pursuant to Section  11.1).
Without  limiting the  generality of the foregoing,  Tenant shall:  (i) keep the

mechanical  installations  therein,  in good order and repair and shall make all
replacements  thereof  from time to time  required  by any  governmental  agency
having jurisdiction thereover;  (ii) surrender the Premises at the expiration of
the Term or at such other time as Tenant  may  vacate  the  Premises  in as good
condition as when received, except for (A) ordinary wear and tear, (B) damage by
Casualty  (other than such damage by  Casualty  which is caused,  in whole or in
part,  by the  negligence  or willful acts or  omissions of Tenant,  its agents,
concessionaires,  officers,  employees,  licensees,  invitees or contractors and
which is not wholly covered by Landlord's hazard insurance policy),  or (C) acts
of God; and (iii) take care not to overload the  electrical  wiring  serving the
Premises  or within the  Premises,  and install at its  expense,  subject to the
provision of Section 9.4, any additional electrical, mechanical, plumbing or any
other  equipment  which may be required in connection  with the  Permitted  Use.
Except for the  provisions  of  Section  9.3  hereof,  nothing  herein  shall be

Premises or to the  structural  components of the Building  passing  through the
Premises or any building systems found therein.

      (b) Any damage or injury  sustained by any person  because of  mechanical,
electrical, plumbing or any other equipment or installation, the maintenance and

shall be paid for by Tenant,  and Tenant shall  indemnify  and hold Landlord and
any  Mortgagee  harmless  from and  against  all  claims,  actions,  damages and
liabilities in connection therewith,  including,  but not limited to, attorneys'
and other  professional fees and any other costs which Landlord or any Mortgagee
incurs by reason  thereof,  regardless of whether formal legal  proceedings  are
instituted.

      Section 9.3.      Tenant's Duty to Repair Damage.

      Tenant shall repair promptly,  at its expense,  any damage to the Premises
(and upon  demand,  shall  reimburse  Landlord for the cost of the repair of any
damage  occurring  elsewhere  in  the  Project),   caused  by  Tenant,  Tenant's
contractors,  Tenant's suppliers,  independent contractors,  agents,  employees,
concessionaires  or licensees or any other persons in bringing into the Premises
any  property  for  Tenant's  use,  or by the  installation  or  removal of such
property,  regardless  of fault or by whom such damage  shall be caused  (unless
caused solely by Landlord, its agents, employees or contractors). Any repairs or
alterations  to the Premises which may affect the structure or appearance of the
Premises,  any Common Areas or any portion of the Building or the Project, shall
require the prior written  consent  thereto by Landlord and Landlord  shall have
the absolute  right to withhold its consent and require  alternative  methods of
repair and  alteration if the making  thereof  will,  in  Landlord's  reasonable
opinion,  adversely  affect the Premises,  the Common Areas, the Building or the
Project.  In default of the making of such repairs by Tenant,  at the expiration
of ten (10) calendar days after notice to Tenant, Landlord may make such repairs
or cause the same to be made,  and  Tenant  agrees to pay to  Landlord  the cost
thereof  promptly upon Landlord's  demand,  as Additional Rent, with interest at
the Default Rate until paid.

      Section 9.4.      Alterations by Tenant.

      Tenant shall not make any alterations,  renovations, improvements or other
installations to the Premises (including, without limitation, any alterations of
the signs,  structural  alterations  or any cutting or drilling into any part of
the Premises)  unless and until: (i) Tenant shall have caused detailed plans and
specifications  therefor  to have  been  prepared  and  delivered,  at  Tenant's
expense, by a licensed architect or other duly qualified person, and (ii) Tenant
shall have obtained  Landlord's prior written approval  thereof,  which approval
shall not be  unreasonably  withheld,  conditioned  or  delayed.  If approval is
granted,  Tenant shall cause the work described in such plans and specifications
to be performed, at its expense,  promptly,  efficiently and competently by duly
qualified  or  licensed  persons  or  entities  without   interference  with  or
disruption  of the  operations  of tenants or other users and  occupants  of the
Building  or the  Project.  All such  work  shall  comply  with  all  applicable
governmental codes, rules, regulations and ordinances.

      Section 9.5.      Landlord's Right of Access.

      Landlord and its  authorized  representatives  may: (a) enter the Premises
(i) during normal  business  hours for the purpose of inspecting any repairs and
alterations  being made or required to be made by Tenant  hereunder,  or (ii) at
any  other  time  Landlord  deems  reasonably  necessary  to  prevent  waste and
deterioration of the Premises,  the Building or the Project; (b) use exclusively
all or any part of the  roof,  if any,  of the  Premises,  the  Building  or the
Project  for  any  purpose,  including,  without  limitation,  the  erecting  of
temporary  scaffolds  and other  aids to  construction  on the  exterior  of the
Premises, the Building or the Project, provided access to the Premises shall not
be denied;  (c) install,  maintain,  use, repair and replace within the Premises
pipes, ducts,  conduits,  wires, access doors and all other mechanical equipment
serving  other  parts of the  Building  or the  Project,  the same to be at such
locations  within  the  Premises  as will not  unreasonably  deny  Tenant's  use
thereof;  and (d)  make  any use it  desires  of the  side or rear  walls of the
Premises,  provided  that such use shall not  encroach  on the  interior  of the
Premises.

      Section 9.6.      Disruption in Business Operations.

      Landlord shall take all reasonable  measures to minimize disruption to and
impact on the business  operations  of Tenant with respect to any actions  taken
herein.  If,  however,  Tenant's  business  operations  within the  Premises are
materially disrupted due to any act of Landlord or any of its employees, agents,
representatives,  successors or assigns,  and such material disruption continues
for more than three (3) consecutive  business days,  Tenant's  obligation to pay
Rent  (other  than any  Additional  Rent due by reason of  Tenant's  failure  to
perform any of its other obligations  hereunder) shall be abated during any such
time.

      Section 10.3.     Policy Requirements.

      (a) The  company  or  companies  writing  any  insurance  which  Tenant is
required  to take  out and  maintain  or cause  to be  taken  out or  maintained
pursuant to Sections 10.1 and 10.2, as well as the form of such insurance, shall
at all  times  be  subject  to  Landlord's  approval,  and any such  company  or
companies  shall be admitted to do business in the  Commonwealth of Virginia and
have a current Best rating of at least A-VII.  Commercial liability and all-risk
property insurance policies evidencing such insurance shall name Landlord and/or
its  designees  (including,  without  limitation,  any  Mortgagee) as additional
insureds,  shall be  primary  and  noncontributory,  and  shall  also  contain a

<PAGE>

advance  written  notice  to  Landlord   and/or  such  designees.   Certificates
evidencing  coverage shall be deposited with Landlord promptly upon commencement
of Tenant's  obligation to procure the same.  None of the insurance which Tenant
is required to carry shall contain deductible provisions in excess of $2,500.00,
unless  approved  in writing in advance  by  Landlord.  If Tenant  shall fail to
perform any of its obligations pursuant to this Article 10, Landlord may perform
the same and the cost thereof shall be payable upon  Landlord's  demand therefor
as  Additional  Rent,  with  interest  thereon at the Default Rate until paid in
full.

      (b) Landlord and Tenant agree that on January 1, 2001, and on January 1 of
every second (2nd) year  thereafter,  Landlord  will have the right to request a
change in the character  and/or  amounts of insurance  required to be carried by
Tenant pursuant to the provisions of this Article 10. Provided that such changes
are consistent  with insurance  required to be carried by tenants in first-class
office projects in the Washington,  D.C. - Northern  Virginia area, Tenant shall
comply with the requested  change in character  and/or amount within thirty (30)
days of Landlord's request therefor.

      Section 10.4.     Indemnities by Tenant and Landlord.

      (a) Notwithstanding any policies of insurance required of Tenant,  Tenant,
for itself and its successors and assigns, to the extent permitted by law, shall
defend,  indemnify and hold harmless Landlord and any Mortgagee against and from
all liability or claims asserted by any person against,  or incurred by Landlord
in  connection  with:  (i) the use,  occupancy or  management of the Premises by
Tenant  or any of  its  agents,  contractors,  servants,  employees,  licensees,
concessionaires, suppliers or materialmen during the Term; or (ii) any breach or
default in performing any of the obligations  under the provisions of this Lease
and/or  applicable  law by Tenant or any of its agents,  contractors,  servants,
employees,  licensees,  suppliers or  materialmen  during the Term; or (iii) any
negligent,  intentionally  tortious or other act or omission by Tenant or any of
its  agents,  contractors,  servants,  employees,  licensees,   concessionaires,
suppliers,  materialmen  or invitees  during the Term;  or (iv) any injury to or
death of any person or any damage to any property  occurring  upon the Premises,
and from and against all costs,  expenses and liabilities incurred in connection
with  any  claim,  action,  demand,  suit  at  law,  in  equity  or  before  any
administrative  tribunal,  arising  in whole or in part by  reason of any of the
foregoing (including,  by way of example rather than of limitation,  the fees of
attorneys,  investigators  and experts),  all  regardless of whether such claim,
action or proceeding is asserted  before or after the  expiration of the Term or
any earlier termination of this Lease.

      (b) If any such claim,  action or proceeding is brought  against  Landlord
and/or any Mortgagee,  Tenant shall  promptly,  if requested by Landlord or such
Mortgagee,  and at Tenant's  expense,  resist or defend  such  claim,  action or
proceeding or cause it to be resisted or defended by an insurer. Landlord shall,
at its  option,  be  entitled  to  participate  in  the  selection  of  counsel,
settlement and all other matters pertaining to such claim, action or proceeding,
all of which shall be subject,  in any case,  to the prior  written  approval of
Landlord.

      (c) Subject to the provisions of Section 10.5,  Landlord hereby agrees for
itself and its successors and assigns to indemnify and save Tenant harmless from
and against any liability or claims of liability arising solely out of the gross
negligence  or  intentional  acts and  omissions  of  Landlord,  its  agents  or
employees.

<PAGE>
      Section 10.5.     Landlord Not Responsible for Acts of Others.

      Landlord  shall  not be  responsible  or  liable  to  Tenant,  or to those
claiming  by,  through  or under  Tenant,  for any loss or  damage  which may be
occasioned  by or through the acts or  omissions  of persons  occupying or using
space  adjoining  the  Premises  or any  part  of the  premises  adjacent  to or
connecting  with the  Premises or any other part of the Building or the Project,
or for any loss or damage  resulting to Tenant (or those claiming by, through or
under Tenant) its or their property,  from the breaking,  bursting,  stoppage or
leaking of electrical cable and wires, and water,  gas, sewer or steam pipes. To
the  maximum  extent  permitted  by law,  Tenant  agrees to use and  occupy  the
Premises,  and to use such other  portions of the Building  and the Project,  as
Tenant is herein given the right to use, at Tenant's own risk.

      Section 10.6.     Landlord's Insurance.

      During  the  Term,  to  the  extent  deemed  reasonable  or  necessary  in
Landlord's  sole  discretion,  Landlord  shall  maintain  (a)  insurance  on the
Building  and the Project  against loss or damage by fire and all of the hazards
included in the extended coverage endorsement, in an amount deemed reasonable by
Landlord, (b) comprehensive liability and property damage insurance with respect
to the Common  Areas,  against  claims for personal  injury or death or property
damage  suffered  by  others  occurring  in, on or about  the  Building  and the
Project,  such public liability  insurance to afford protection in limits deemed
reasonable by Landlord,  and (c) any other  insurance,  in such form and in such
amounts as are deemed  reasonable by Landlord,  including,  without  limitation,
rent  continuation  and business  interruption  insurance,  theft  insurance and
worker's compensation, flood and earthquake, and boiler and machinery insurance.
The costs and expenses of any and all insurance  carried by Landlord pursuant to
the provisions of this Section 10.6 shall be deemed a part of Operating Costs.

      Section 10.7.     Increase in Insurance Premiums.

      Tenant  shall not do or  suffer to be done,  or keep or suffer to be kept,
anything  in,  upon or about  the  Premises  which  will  contravene  Landlord's
policies of hazard or liability  insurance or which will prevent  Landlord  from
procuring such policies from companies acceptable to Landlord. If anything done,
omitted  to be done or  suffered  by  Tenant  to be kept in,  upon or about  the
Premises  shall cause the rate of fire or other  insurance on the Premises or on
other property of Landlord or of others within the Building or the Project to be
increased  beyond the minimum rate from time to time  applicable to the Premises
or to any such other property for the use or uses made thereof, Tenant shall pay
to Landlord, as Additional Rent, the amount of any such increase upon Landlord's
demand therefor.

      Section 10.8.     Waiver of Right of Recovery.

      All policies covering real or personal property which either party obtains
affecting  the  Premises,  the Building or the Project shall include a clause or
endorsement  denying  the insurer  any rights of  subrogation  against the other
party to the extent rights have been waived by the insured before the occurrence
of injury or loss.  Notwithstanding  anything herein  contained to the contrary,
Landlord  and Tenant  waive any rights of  subrogation  or recovery  against the
other for damage or loss to their respective  property due to hazards covered or
which should be covered by policies of insurance  obtained or which should be or
have been obtained  pursuant to this Lease,  to the extent of the injury or loss
covered or which should have been covered thereby,  assuming that any deductible
shall be deemed to be insurance coverage.

                                    CASUALTY

      Section 11.1.     Obligation to Repair and Reconstruct.

      If the Building shall be damaged by fire, the elements,  accident or other
casualty  (collectively,  "Casualty"),  but the  Premises  shall not  thereby be
rendered wholly or partially  untenantable,  then,  subject to the provisions of
Section 11.2, Landlord shall promptly cause such damage to be repaired and there
shall be no abatement of Rent. If as the result of Casualty,  the Premises shall
be rendered wholly or partially untenantable, then, subject to the provisions of
Section  11.2,  Landlord  shall cause such  damage to be  repaired  and all Rent
(other than any Additional Rent due Landlord by reason of Tenant's prior failure
to perform any of its obligations  hereunder) shall be abated proportionately as
to the portion of the Premises rendered  untenantable  during the period of such
untenantability.  All such repairs shall be made at the expense of Landlord, but
Landlord  shall not be required to repair any work  performed by or on behalf of
Tenant or to expend  any  amounts  in excess of the net  proceeds  of  insurance
received by  Landlord.  In  performing  its  rebuilding  obligations  hereunder,
Landlord shall have the right to make modifications to the structures comprising
the  Building,  the Project and the Premises.  Landlord  shall not be liable for
interruption  to Tenant's  business or for damage to or replacement or repair of
Tenant's Property or to any leasehold  improvements installed in the Premises by
or on behalf of Tenant,  all of which  damage,  replacement  or repair  shall be
undertaken and completed promptly by Tenant at Tenant's expense.

      Section 11.2.     Option to Terminate Lease.

      If (a) the Premises are rendered wholly untenantable,  or (b) the Premises
are  damaged  as a result  of any  cause  which  is not  covered  by  Landlord's
insurance,  or (c) the  Premises  are damaged or  destroyed  in whole or in part
during the last two (2) Lease Years of the Term,  or (d) the Building is damaged
to the extent of fifty  percent (50%) or more of its GRA, or (e) the Building is
so substantially damaged that Landlord determines,  in Landlord's sole judgment,
to demolish the Building, then and in any of such events, Landlord or Tenant may
elect to terminate this Lease by giving Tenant or Landlord,  as the case may be,
notice of such  election  within  ninety (90) days after the  occurrence of such
event. If such notice is given,  the rights and obligations of the parties shall
cease as of the date of such notice,  and Rent (other than any  Additional  Rent
due  Landlord  by reason of Tenant's  failure to perform any of its  obligations
hereunder) shall be adjusted as of the date of such termination.

      Section 11.3.     Insurance Proceeds.

      If Landlord  does not elect to  terminate  this Lease  pursuant to Section
11.2,  then,  subject  to the prior  rights  of any  Mortgagee,  Landlord  shall
disburse  and apply any net  insurance  proceeds  received  by  Landlord  to the
restoration  and rebuilding of the Building in accordance with Section 11.1. All
insurance  proceeds  payable with respect to the  Premises  (excluding  proceeds
payable  to Tenant  pursuant  to  Section  10.1),  shall  belong to and shall be
payable to Landlord.

                                  CONDEMNATION

      Section 12.1.     Effect of Taking.

      If the whole or any part of the  Premises  shall be taken  pursuant to the
power of eminent domain,  whether by condemnation or deed in lieu thereof,  this
Lease  shall  terminate  as to the part so taken as of the date of such  taking.
Landlord shall make such repairs and alterations as may be necessary in order to
restore the part of the  Premises not taken to a useful  condition  and all Rent
(other than any Additional Rent due Landlord by reason of Tenant's prior failure
to  perform  any of its  obligations  hereunder)  shall be  reduced  in the same
proportion  as the  portion of the  Premises  so taken.  If any  partial  taking
renders the  remainder of the Premises  unusable for the Permitted  Use,  either
party may terminate this Lease as of the date of such taking by giving notice to
the other  party  within  thirty  (30) days  after  such  date.  Notwithstanding
anything contained herein to the contrary, if fifty percent (50%) or more of the
Premises is taken as aforesaid,  Tenant may elect to terminate  this Lease as of
the date of such taking,  by providing  written  notice of such  termination  to
Landlord  within  thirty (30) days of such date. If ten percent (10%) or more of
the Building is taken as aforesaid,  Landlord may elect to terminate  this Lease
as of the date of such taking by giving notice of such election to Tenant within
ninety (90) days after such date. If any notice of termination is given pursuant
to this Section 12.1,  this Lease and the rights and  obligations of the parties
hereunder  shall cease on the date  specified in such notice and all Rent (other
than any  Additional  Rent due Landlord by reason of Tenant's  prior  failure to
perform any of its  obligations  hereunder)  shall be adjusted as of the date of
such termination.

      Section 12.2.     Condemnation Awards.

      All compensation  awarded for any taking of the Premises or any portion of
the  Building or any interest in any of them shall belong to and be the property
of Landlord or any  Mortgagee,  and Tenant hereby assigns to Landlord all rights
with respect thereto; provided,  however, nothing contained herein shall prevent
Tenant  from  seeking in a separate  action  reimbursement  from the  condemning
authority (if permitted by law) for moving  expenses and expenses for removal of
Tenant's Property, but if and only if such action shall not reduce the amount of
the  award or  other  compensation  otherwise  recoverable  from the  condemning
authority by Landlord or any Mortgagee.

                                   ARTICLE 13

                            ASSIGNMENT AND SUBLETTING

      Section 13.1.     Landlord's Consent Required.

      (a) Except as otherwise provided  hereinbelow,  throughout the Term Tenant
shall not assign this Lease,  in whole or in part, nor sublet all or any part of
the Premises, nor otherwise permit any other Person to occupy or use any portion
of the Premises  (collectively  a  "Transfer"),  without in each instance  first
obtaining  the  written  consent  of  Landlord,   which  consent  shall  not  be
unreasonably  withheld,  conditioned  or delayed.  Landlord's  consent  shall be
deemed to be reasonably  withheld if any proposed  Transfer is to a governmental
or  quasi-governmental  entity, if the proposed  Transferee would  detrimentally
alter the  Permitted  Use of the Premises or use the Premises in a manner not in

<PAGE>

keeping  with the image of the  Project,  or if the  financial  condition of the
proposed Transferee is not reasonably  acceptable to Landlord.  This prohibition
includes any subletting or assignment  which would  otherwise occur by operation
of law or by an  assignment  or subletting to or by a receiver or trustee in any
Federal or State  bankruptcy or similar  proceeding.  Consent by Landlord to any
Transfer  shall not constitute a waiver of the  requirement  for such consent to
any subsequent assignment,  subletting,  licensing or other Transfer, or relieve
Tenant from its obligations under this Lease.

      (b) Notwithstanding  the foregoing,  Tenant shall be entitled to assign or
sublet the Premises,  in whole or in part,  without the prior written consent of
Landlord, to any Affiliate (defined below) of Tenant. Tenant shall give Landlord
written notice of any such Transfer at least thirty (30) days prior thereto.  As
used in this Section 13.1, the term "Affiliate"  means any entity which directly
or  indirectly  controls or is  controlled  by or is under  common  control with
Tenant.  For purposes of this definition,  "control"  (including the correlative
meaning of the terms "controlled by" and "under common control with") shall mean
the  possession,  directly  or  indirectly,  of the power to direct or cause the
direction of the management and policies of such an entity,  whether through the
ownership of voting stock or securities or by contract or otherwise.

      Section 13.2.     Transfer; Issuance of Corporate Shares.

      If Tenant is a  corporation  (other  than a  corporation  the  outstanding
voting stock of which is listed on an  "exchange,"  as defined in the Securities
Exchange Act of 1934),  Tenant shall give Landlord  notice  within  fifteen (15)
days  following the date upon which  additional  voting stock shall be issued by
Tenant,  or any  part  or all  of  the  corporate  shares  of  Tenant  shall  be
Transferred,  in the event that such Transfer results in a change in the present
control of Tenant or if more than fifty percent (50%) of said  corporate  shares
are  Transferred.  In the event of a Transfer  in which more than fifty  percent
(50%) of  Tenant's  voting  stock is sold to a party that is  unaffiliated  with
Tenant,  which  Transfer  shall  result  in  Tenant  vacating  the  Premises  or
undergoing a material change in the business conducted by Tenant, and whether or
not  Tenant has given such  notice,  Landlord  may  elect,  in  Landlord's  sole
discretion,  to either  terminate  this Lease at any time  thereafter by written
notice  to  Tenant  (and in the  event of any  termination,  all  Rent  shall be
adjusted  as of the date of such  termination),  or deem the  Transfer  to be an
Event or Default,  entitling  Landlord to the rights and  remedies  set forth in
Section 14.2.

      Section 13.3.     Acceptance of Rent from Transferee.

      The  acceptance  by  Landlord  of the  payment  of Rent  from  any  person
following  any Transfer  prohibited  by this Article shall not be deemed to be a
consent  by  Landlord  to such  Transfer,  nor  shall the same be deemed to be a
waiver of any right or remedy of Landlord's hereunder.

      Section 13.4.     Conditions of Consent.

      (a) If Tenant  receives  consent to a Transfer  under  Section 13.1 above,
then, in addition to any other terms and  conditions  imposed by Landlord in the
giving of such consent,  Tenant and the Transferee shall execute and deliver, on
demand,  an agreement  prepared by Landlord  which  agreement in any event shall
provide:  (i) that the Transferee shall be directly bound to Landlord to perform
all  obligations  of  Tenant  hereunder  including,   without  limitation,   the
obligation  to pay all Rent and other  amounts  provided  for herein;  (ii) that

<PAGE>

there shall be no subsequent Transfer of this Lease or of the Premises or of any
interest therein without the prior consent of Landlord  pursuant to Section 13.1
above;  (iii) that Tenant as  originally  named herein shall remain fully liable
for all  obligations  of Tenant  hereunder,  including the obligation to pay all
Rent provided  herein and including any and all  obligations  arising out of any
subsequent  amendments  to this Lease made between  Landlord and the  Transferee
(whether  or not  consented  to by  Tenant),  jointly  and  severally  with  the
Transferee; and (iv) such other provisions as Landlord shall reasonably require.

      (b) All costs  incurred  by Landlord  in  connection  with any request for
consent to a Transfer,  including costs of investigation and the reasonable fees
of Landlord's counsel,  shall be paid by Tenant on demand as a further condition
of any consent which may be given.

      Section  13.5.  Profits  from Use or Transfer.  Tenant  agrees that in the
event of a  Transfer,  Tenant  shall pay  Landlord  fifty  percent  (50%) of all
amounts received by Tenant or payable to Tenant in connection with such Transfer
in excess of Tenant's obligations  hereunder (less Tenant's actual out-of-pocket
expenses associated with such Transfer).

                                   ARTICLE 14

                                     DEFAULT

      Section 14.1.     "Event of Default" Defined.

      Any one or more of the following  events shall  constitute a default under
the terms of this Lease ("Event of Default"):

      (a) failure of Tenant to pay any Rent or other sum of money due  hereunder
to Landlord or any other  person  within ten (10)  calendar  days after  written
notice thereof from Landlord that the same is due;

      (b) sale of Tenant's interest in the Premises under attachment,  execution
or similar legal process or otherwise without Landlord's approval;

      (c)  filing  of a  petition  proposing  the  adjudication  of  Tenant as a
bankrupt or insolvent,  or the  reorganization  of Tenant,  or an arrangement by
Tenant with its creditors, whether pursuant to the Federal Bankruptcy Act or any
similar  Federal or state  proceeding,  unless such petition is filed by a party
other than Tenant and is withdrawn or dismissed within sixty (60) days after the
date of its filing;

      (d)  admission in writing by Tenant of its inability to pay its debts when
due;

      (e)  appointment  of a receiver or trustee for the business or property of
Tenant,  unless such appointment shall be vacated within thirty (30) days of its
entry;

      (f)  making by Tenant of an assignment for the benefit of its
creditors; and

      (g) default by Tenant in the  performance or observance of any covenant or
agreement of this Lease to be performed or observed by Tenant (other than as set
forth in clauses  (a)  through (f)  above),  which  default is not cured  within
thirty  (30) days after the giving of notice  thereof by  Landlord,  unless such

<PAGE>

default is of such  nature  that it cannot be cured  within said thirty (30) day
period,  in which event an Event of Default shall not be deemed to have occurred
if Tenant  institutes  a cure within such thirty (30) day period and  thereafter
diligently and continuously prosecutes the curing of same until completion,  but
in no event shall such cure period exceed ninety (90) days.

      Provided,  however, that if Tenant shall default in the performance of the
same or any similar  covenant or  agreement  two (2) or more times in any twelve
(12) month period, then  notwithstanding that such defaults have each been cured
by Tenant,  any  further  similar  defaults  shall be deemed an Event of Default
without the ability to cure.

      Section 14.2.     Remedies.

      Upon the  occurrence of an Event of Default,  Landlord,  without notice to
Tenant in any instance (except where expressly  provided for below),  may do any
one or more of the following:

      (a) Landlord may accelerate the Rent and any other charges, whether or not
stated to be Additional Rent  hereunder,  for the entire balance of the Term and
any renewal or extension  thereof,  or any part of such Rent,  and any costs and
sheriff's  or other  commissions,  whether  chargeable  to  Landlord  or Tenant,
including  watchmen's wages, as if by the terms of this Lease the balance of the
Rent and other charges were on that date payable in advance.

      (b)  Landlord may elect to  terminate  this Lease and the tenancy  created
hereby by giving  notice  to Tenant  without  any right on the part of Tenant to
save  the  forfeiture  by  payment  of any sum due or by  other  performance  of
condition or covenant  broken.  Landlord  may also elect to  terminate  Tenant's
possessory  rights and all other rights of Tenant  without  thereby  terminating
this Lease.  Landlord may, without notice,  reenter the Premises,  breaking open
locked doors, if necessary,  to effect  entrance,  for the purpose of recovering
possession  of the  Premises,  and may  proceed  to  recover  possession  of the
Premises by process of law,  any notice to quit or of  intention to re-enter the
Premises being expressly waived by Tenant. Landlord may remove Tenant and remove
all other persons and property  from the Premises,  and store such property in a
public  warehouse  or  elsewhere  at the cost of and for the  account  of Tenant
without  resort to legal  process and without  Landlord  being deemed  guilty of
trespass  or  becoming  liable  in any  way for any  loss or  damage  occasioned
thereby,  and take possession of and sell under such lien the goods and chattels
found in the Premises.

      (c) When this Lease shall be  terminated  by reason of an Event of Default
or when the Term has  expired,  any  attorney  for  Landlord  may proceed in any
competent  court for  judgment  in  ejectment  against  Tenant  and all  persons
claiming under Tenant for the recovery of possession of the Premises. If for any
reason  after such  action  shall have been  commenced,  it shall be canceled or
suspended and  possession  of the Premises  remains in or is restored to Tenant,
Landlord shall have the right upon any subsequent default or upon the expiration
or termination of this Lease to bring one or more actions to recover  possession
of the Premises.

      (d) If, in any action  for the  enforcement  of this  Lease,  Landlord  is
required to file a copy of this  Lease,  it shall not be  necessary  to file the
original,  notwithstanding  any law or practice to the  contrary.  Tenant hereby
waives all procedural  errors in any proceedings  taken by Landlord,  whether by
virtue  of the  powers  of  attorney  contained  in this  Lease or not,  and all

<PAGE>

liability  therefor.  Tenant further waives the right to any notice to remove or
any similar or successor  provision of any applicable  law, and agrees that five
(5) days' notice shall be  sufficient  in any case where a longer  period may be
statutorily specified.

      (e)  Landlord  may  perform,  on behalf and at the expense of Tenant,  any
obligation  of Tenant under this Lease which Tenant has failed to perform and of
which Landlord shall have given Tenant notice,  the cost of which performance by
Landlord,  together with  interest  thereon at the Default Rate from the date of
such expenditure, shall be deemed Additional Rent and shall be payable by Tenant
to Landlord upon demand therefor.

      (f) Landlord  may  exercise  any other legal or equitable  right or remedy
which it may have at law or in equity,  including rights of specific performance
and/or injunctive relief, where appropriate.

      Section 14.3.     Damages.

      (a) If this Lease is  terminated  by Landlord  pursuant  to Section  14.2,
Tenant  shall  remain  liable  for any  Rent  and  damages  which  may be due or
sustained  prior to such  termination  and all  reasonable  costs and  expenses,
including,   without  limitation,   sheriffs'  or  other  commissions   (whether
chargeable to Landlord or Tenant),  watchmen's  wages,  brokers' and  attorneys'
fees,  and repair and  renovation  costs  incurred by Landlord in pursuit of its
remedies  hereunder,  and/or in connection  with any  bankruptcy  proceedings of
Tenant,  and/or in  connection  with renting the Premises to others from time to
time (all such Rent, damages,  costs, fees and expenses being referred to herein
as "Termination  Damages"),  plus additional  damages for all Rent treated as in
arrears ("Liquidated  Damages") which, at the election of Landlord,  shall be an
amount equal to either:


            (i) the Rent which,  but for the  termination  of this Lease,  would
have become due during the  remainder of the Term,  less the amount of rent,  if
any,  which  Landlord  shall receive  during such period from others to whom the
Premises may be rented (other than any additional rent received by Landlord as a
result of any failure of such other person to perform any of its  obligations to
Landlord),  in which case  Liquidated  Damages  shall be computed and payable in
monthly  installments,  in  advance,  on the  first day of each  calendar  month
following the  termination  of this Lease and shall  continue  until the date on
which the Term would have  expired but for such  termination,  and any action or
suit brought to collect any such  Liquidated  Damages for any month shall not in
any manner prejudice the right of Landlord to collect any Liquidated Damages for
any subsequent months by similar preceding; or

            (ii) the present worth (as of the date of such  termination)  of the
Rent which, but for the termination of this Lease,  would have become due during
the  remainder  of the Term,  less the fair  rental  value of the  Premises,  as
determined by an  independent  real estate  appraiser  selected by Landlord,  in
which case such Liquidated  Damages shall be payable to Landlord in one lump sum
on demand and shall bear  interest  at the  Default  Rate until  paid.  "Present
worth" shall be computed by  discounting  such amount to present worth at a rate
equal to one  percentage  point  above the  discount  rate then in effect at the
Federal  Reserve  Bank.  In no event  shall  Landlord  be required to account to
Tenant for any amounts by which the fair rental  value shall have  exceeded  the
stipulated Rent at the time of such termination.

<PAGE>
      (b) If this Lease is  terminated  pursuant to Section  14.2,  Landlord may
(without so obligating itself) relet the Premises or any part thereof,  alone or
together  with other  premises,  for such term or terms (which may be greater or
less than the period which otherwise  would have  constituted the balance of the
Term) and on such terms and  conditions  (which may include  concessions or free
rent  and  alterations  of the  Premises)  as  Landlord  may  determine,  in its
commercially  reasonable  discretion,  but Landlord shall not be liable for, nor
shall Tenant's obligations  hereunder be diminished by reason of, any failure by
Landlord  to relet the  Premises  or any failure by Landlord to collect any rent
due upon such reletting.

      (c)  Notwithstanding  anything to the  contrary  set forth in this Section
14.3, in the event (i) Landlord must initiate legal action to enforce any one or
more of the provisions of this Lease against Tenant,  its successors or assigns,
or (ii) Landlord must consult with and/or engage an  attorney(s) in order (A) to
enforce any one or more of the  provisions of this Lease  against  Tenant or its
successors or assigns,  or (B) in connection  with any bankruptcy  proceeding of
Tenant,  whether  or not such  consultation  and/or  engagement  results  in the
initiation of any judicial action or termination of this Lease,  then and in any
of such events, Tenant, its successors and assigns, undertakes and agrees to pay
all costs  incurred by Landlord in connection  therewith,  including,  by way of
illustration and not of limitation, all reasonable attorneys' fees (inclusive of
consultation  fees,  research costs and  correspondence  fees),  court costs (if
awarded  post-judgment)  and any similar  professional  fees or costs associated
therewith,  which costs shall accrue  interest at the Default Rate until paid in
full.

               SUBORDINATION, ATTORNMENT AND NON-DISTURBANCE

      Section 15.1.     Subordination.

      (a) Unless a Mortgagee  shall otherwise elect as provided in Section 15.2,
Tenant's rights under this Lease are and shall remain subject and subordinate to
the  operation  and  effect  of any  mortgage,  deed of trust or other  security
instrument  constituting a lien upon the Building,  whether the same shall be in
existence  at the date hereof or created  hereafter  (any such lease,  mortgage,
deed of trust  or other  security  instrument  being  referred  to  herein  as a
"Mortgage," and the party or parties having the benefit of the same,  whether as
mortgagee,  beneficiary,  trustee or  noteholder,  being referred to hereinafter
collectively  as  a  "Mortgagee").  Tenant's  acknowledgment  and  agreement  of
subordination  as provided  for in this Section  15.1 is  self-operative  and no
further  instrument of subordination  shall be required;  however,  Tenant shall
execute,  within ten (10) days after request therefor,  such further  assurances
thereof  as shall  be  requisite  or as may be  requested  from  time to time by
Landlord  or any  Mortgagee.  Notwithstanding  the  foregoing,  Tenant  shall be
entitled to condition  its agreement to  subordinate  this Lease as aforesaid to
the  providing  to  Tenant  of  assurances  of  non-disturbance  from  any  such
Mortgagee.

      (b) Landlord hereby directs Tenant, upon (i) the occurrence of an event of
default by Landlord, as mortgagor under any Mortgage, (ii) the receipt by Tenant
of a notice of the  occurrence of such event of default under such Mortgage from
Landlord or such  Mortgagee,  and (iii) a direction by the Mortgagee  under such
Mortgage to Tenant to pay all Rent  thereafter to such  Mortgagee,  to make such
payments to such  Mortgagee,  and Landlord  agrees that in the event that Tenant
makes such payments to such Mortgagee, as aforesaid,  Tenant shall not be liable
to Landlord for the same.
<PAGE>

      Section 15.2.     Mortgagee's Unilateral Subordination.

      If a Mortgagee shall so elect by notice to Tenant or by the recording of a
unilateral  declaration  of  subordination,   this  Lease  and  Tenant's  rights
hereunder  shall be  superior  and prior in right to the  Mortgage of which such
Mortgagee  has the benefit,  with the same force and effect as if this Lease had
been  executed,  delivered  and recorded  prior to the  execution,  delivery and
recording of such Mortgage, subject,  nevertheless, to such conditions as may be
set forth in any such notice or declaration.


      Section 15.3.     Attornment and Non-disturbance.

      If any person shall succeed to all or any part of  Landlord's  interest in
the Premises,  whether by purchase,  foreclosure,  deed in lieu of  foreclosure,
power   of   sale,   termination   of   lease,   or   otherwise,   and  if  such
successor-in-interest   requests  or  requires,  Tenant  shall  attorn  to  such
successor-in-interest  and shall  execute  within  ten (10) days  after  receipt
thereof such agreement in  confirmation  of such  attornment in accordance  with
that form attached hereto as Schedule G. Failure to respond within such (10) day
period shall be deemed to be a  confirmation  by Tenant of the facts and matters
set  forth  therein.  Tenant  hereby  agrees  that  any  suit,  action  or other
proceeding  commenced  by any  Mortgagee  in order to  realize  upon  Landlord's
interest in, under and to this Lease, or any part of the Building, shall not, by
operation of law or otherwise, result in the cancellation or termination of this
Lease or of the obligations of Tenant hereunder.

                                   ARTICLE 16

                                 QUIET ENJOYMENT

      Landlord  covenants  and agrees  with  Tenant  that  Tenant  shall and may
peaceably and quietly have,  hold and enjoy the Premises for the Term, free from
any interference  whatsoever by, from or through Landlord or anyone claiming by,
from or through Landlord, except as may be otherwise provided herein.

Lease  shall be in  writing  and shall be deemed to have been given on the third
(3rd) day  following  the day on which the same shall have been mailed by United
States registered or certified mail, return receipt  requested,  with all postal
charges  prepaid,  or given the next day if sent by national  overnight  courier

Landlord or Tenant to the respective  notice addresses set forth in the preamble
paragraph  of this  Lease  and/or  such  other  addresses  as  either  party may
designate to the other by notice in accordance with this Section 17.1.

      Section 17.2.     Notices to Mortgagees.

      If any  Mortgagee  shall notify Tenant that it is the holder of a Mortgage
affecting the Premises,  and shall  thereby  request  copies of all notices from
Tenant, no notice, request or demand thereafter sent by Tenant to Landlord shall

<PAGE>

be  effective  unless  and until a copy of the same  shall  also be sent to such
Mortgagee in the manner  prescribed  in Section 17.1 and to such address as such
Mortgagee shall designate.

      Section 17.3.     Estoppel Certificate.

      Tenant  agrees from time to time,  upon not less than ten (10) days' prior
written request by Landlord,  to execute,  acknowledge and deliver to Landlord a
statement in writing,  in the form attached as Schedule H,  certifying that this
Lease  is  unmodified  and in full  force  and  effect  and that  Tenant  has no
defenses,  offsets or counterclaims against its obligations to pay the Base Rent
and Additional Rent and to perform its other  obligations  under this Lease, and
that there are no uncured  defaults of Landlord or Tenant under this Lease,  and
the dates  through  which all Rent has been paid,  and all such other or further
matters as are set forth  therein.  The  statement  delivered  pursuant  to this
Section 17.3 may be relied upon by any  purchaser or Mortgagee,  or  prospective
purchaser or Mortgagee, of the Building.

                                   ARTICLE 18

                                  MISCELLANEOUS

      Section 18.1.  Modification.

      It is a condition  that this Lease is subject to the  approval of Teachers
Insurance and Annuity Association of America. In addition,  if in the future and
in connection  with  obtaining  any  financing for the Building,  a lender shall
request reasonable modifications in this Lease as a condition to such financing,
Tenant will not unreasonably withhold,  delay or defer Tenant's consent thereto;
provided,  that the  modification  would not increase the  obligations of Tenant
hereunder or materially  adversely affect the leasehold  interest hereby created
or Tenant's rights granted hereunder.

      Section 18.2.     No Recordation.

      Tenant  hereby  agrees  that  Tenant  shall not  record  this Lease or any
memorandum of this Lease,  unless expressly consented to in writing by Landlord.
The  recordation  of this Lease or memorandum  hereof by Tenant in derogation of
this  Section 18.2 shall be deemed an Event of Default  hereunder,  and Landlord
shall have all of the rights and remedies set forth in Section 14.2,  including,
but not  limited to, the right to  terminate  this Lease and declare all sums of
Rent accruing under this Lease immediately due and payable. In addition,  Tenant
hereby appoints  Landlord as its  attorney-in-fact  for the purpose of executing
such  documents as may be required to nullify  and/or  release this Lease or any
memorandum hereof from the public records.

      Section 18.3.     Remedies Cumulative.

      No reference to any specified right or remedy shall preclude Landlord from
exercising  any other right or from having any other remedy or from  maintaining
any action to which it may otherwise be entitled at law or in equity. No failure
by  Landlord  to insist  upon the strict  performance  of any  agreement,  term,
covenant or condition hereof, or to exercise any right or remedy consequent upon
a  breach  hereof,  and no  acceptance  of  full  or  partial  Rent  during  the
continuance  of any such breach,  shall  constitute a waiver of any such breach,
agreement,  term, covenant or condition.  No waiver by Landlord of any breach by
Tenant  under this Lease or of any  breach by any other  tenant  under any other
lease of any portion of the  Building or the Project  shall affect or alter this
Lease in any way whatsoever.

      Section 18.4.     Successors and Assigns.

      Landlord may, at any time, assign  collaterally or otherwise  transfer any
or all of its right, title and interest in the Building, or any portion thereof,
and this Lease and the covenants and conditions  herein contained shall inure to
the benefit of and be binding upon Landlord,  its  successors  and assigns,  and
shall be binding upon Tenant, its successors and assigns, and shall inure to the
benefit of Tenant  and,  subject to the  provisions  of  Article  12,  only such
assigns  of  Tenant to whom the  assignment  of this  Lease by  Tenant  has been
consented  to by  Landlord.  Upon any sale or other  transfer by Landlord of its
interest in the Premises,  Landlord shall be relieved of any  obligations  under
this Lease accruing thereafter.

      Section 18.5.     Compliance with Laws and Regulations.

      Tenant, at its expense,  shall comply with and shall cause the Premises to

ADA,  environmental laws, rules, orders,  regulations and ordinances)  affecting
the  Premises or any part  thereof,  or the use thereof,  including  those which
require the making of any unforeseen or  extraordinary  changes,  whether or not
any such statutes,  laws, rules, orders,  regulations or ordinances which may be
hereafter  enacted  involve a change  of policy on the part of the  governmental
body  enacting  the same,  and (b) all  rules,  orders  and  regulations  of the
National  Board  of  Fire  underwriters  or  Landlord's  fire  insurance  rating
organization or other bodies exercising similar functions in connection with the
prevention of fire or the correction of hazardous conditions, which apply to the
Premises. In addition,  Tenant shall be solely responsible for obtaining, at its
sole  cost and  expense,  all  occupational  or  business  licenses  or  permits
necessary to operate the Premises for the  Permitted  Use, and the  inability to
obtain the same shall not relieve Tenant from liability hereunder.

liability companies, partnerships or other business associations shall be deemed
to have been given or made by, with or to all of them. In like manner, if Tenant
shall be a partnership or other business association,  the members of which are,
by virtue of any  statute or federal  law,  subject to personal  liability,  the
liability of each such member shall be joint and several.

attorneys' fees in connection therewith.

services, accommodations,  advantages, facilities and privileges of the Building
without discrimination because of race, color, religion, sex or national origin.

affected  thereby,  and each term and provision of this Lease shall be valid and
enforceable to the fullest extent permitted by law.

except  during such hours as are  designated  for such purpose by Landlord,  and
only  after  Tenant  gives  notice  thereof  to  Landlord.  Landlord  shall have
exclusive  right to prescribe  the method and manner in which any of the same is
brought  into or taken out of the  Building,  and the right to exclude  from the
Building any heavy  furniture,  safe or other  article which may create a hazard
and to require it to be located at a designated  place in the  Premises.  Tenant
shall not place any weight  anywhere  beyond the safe  carrying  capacity of the
Building.  The cost of repairing any damage to the Building or any other part of
the Project  caused by taking any of the same in or out of the Premises,  or any
damage  caused  while it is in the  Premises or the rest of the  Building or the
Project, shall be borne by Tenant as Additional Rent.

      11. Without  Landlord's prior written consent:  (a) no connection shall be
made to any  electrical  wire for  running  any fan,  motor or other  apparatus,
device or equipment,  (b) no large  machinery of any kind,  other than customary
small business machinery,  shall be allowed in the Premises, and (c) no mechanic
shall be allowed to work in areas that may affect the base  building  systems in
or about the Building,  other than one employed by Landlord,  unless approved in
writing by Landlord.


<PAGE>

      12.  Landlord shall in no event be responsible  for admitting or excluding
any person from the Premises. In case of invasion, hostile attack, insurrection,
mob violence, riot, public excitement or other commotion, explosion, fire or any
casualty,  Landlord  shall have the right to bar or limit access to the Building
to protect the safety of occupants of the  Project,  or any property  within the
Project.

      13. Landlord shall, as prescribed in the Lease, have the right to rescind,
suspend or modify the Rules and  Regulations  and to promulgate such other Rules
or  Regulations  as, in Landlord's  reasonable  judgment,  are from time to time
needed for the safety,  care,  maintenance,  operation  and  cleanliness  of the
Building and the Project,  or for the  preservation of good order therein.  Upon
Tenant's  having been given notice of the taking of any such  action,  the Rules
and Regulations as so rescinded,  suspended, modified, or promulgated shall have
the same  force and effect as if in effect at the time at which  Tenant's  Lease
was entered  into (except  that  nothing in the Rules and  Regulations  shall be
deemed in any way to alter or impair any provisions of such Lease).

      14. The use of any room  within the  Building  or the  Project as sleeping
quarters is strictly prohibited at all times.

      15.  Tenant  shall keep the windows and doors of the  Premises  (including
those  opening on  corridors  and all doors  between  rooms  entitled to receive
heating or air  conditioning  service  and rooms not  entitled  to receive  such
service),  closed while the heating or air conditioning system is operating,  in
order to minimize the energy used by, and to conserve the effectiveness of, such
system.  Tenant shall comply with all reasonable Rules and Regulations from time
to time promulgated by Landlord with respect to such system or their use.

      16. Nothing in these Rules and Regulations  shall give Tenant any right or
claim  against  Landlord or any other person if Landlord does not enforce any of
them against any other  tenant or person  (whether or not Landlord has the right
to enforce them against such tenant or person),  and no such nonenforcement with
respect to any tenant shall  constitute a waiver of the right to enforce them as
to Tenant or any other tenant or person.

                               DEFINITION OF CAUSE




      CAUSE: "Cause" shall mean any or all of the following: (i) the willful and
continued failure by Employee to perform his duties (other than any such failure
resulting  from  Employee's  incapacity  due to  physical  or mental  illness or
injury)  after  demand  for   performance  is  delivered  by  the  Company  that
specifically  identifies the manner in which the Company  believes  Employee has
not  substantially  performed  his duties,  which failure is not cured within 30
days after written notice is given;  (ii) conduct by Employee  involving  fraud,
dishonesty,  moral turpitude, willful or grossly negligent misconduct, bad faith
or other  conduct  amounting to a breach of Employee's  fiduciary  duties to the
Company (provided,  however,  that in the cause of grossly negligent  misconduct
amounting to a breach of Employee's fiduciary duties to the company that, by its
nature,  is susceptible to cure by subsequent  acts of Employee,  Employee shall
have 30  days  after  demand  by the  Company  to cure  such  grossly  negligent
misconduct);  or (iii) a  failure  by  Employee  to  comply  with  any  material
provision of this Compensation  Letter which failure is not cured within 30 days
after  written  notice of such  noncompliance  has been given by the  Company to
Employee.  For purposes of this  definition of Cause, no act, or failure to act,
by Employee shall be considered "willful" unless done, or omitted to be done, by
him not in good faith and without  reasonable belief that his action or omission
was in the best interest of the Company.
