ITEM  1.  BUSINESS

OVERVIEW

     APACHE  Medical  Systems,  Inc.  ("APACHE"  or  the  "Company")  provides
clinically  based  decision support information systems, research and consulting
services  to  the  healthcare  industry.  The  Company  provides  hospitals  and
physicians with patient-specific, concurrent and predictive outcomes information
at  the  point  of  care  that can be used to assist them in making clinical and
resource  utilization  decisions.  APACHE's  products  and  services address the
information  needs  of  both  healthcare  practitioners  and  administrators  by
enabling joint access to clinical and utilization information, which facilitates
the  containment  of  costs,  and  the delivery of more consistent, high-quality
care, including the potential reduction of medical errors. APACHE's products and
services  are  focused  on high-risk, high-cost patients, such as critical care,
acute  care, cardiovascular care, HIV/AIDS and certain chronically-ill patients,
who  typically  account  for  a  disproportionately  large  share  of healthcare
expenditures.

THE  APACHE(R)  SOLUTIONS

     APACHE  believes  that  its  products  and  services address the healthcare
industry's  need  for  sophisticated  outcomes-based  clinical  decision support
information.  The  APACHE solutions bridge the gap between the information needs
of  healthcare  practitioners  and  those of hospital administrators by enabling
joint access to clinical and cost information, which facilitates the containment
of  cost,  improvement  in  quality outcomes and the consistent delivery of high
quality  care.

     The  Company's  primary decision support system is focused on critical care
and targets hospitals and health systems with over 200 beds. For this market, in
1998  the Company introduced a new product line, the APACHE Critical Care Series
("CCS"),  and a companion set of clinical consulting services marketed under the
APACHE Best Care (TM) Services label. These replaced the Company's previous
Medical Cost Management Program ("MCMP") and related Critical Care System
offerings.  The CCS is compromised of two major modules, Voyager+ and Discover+,
which are described  below.

     Generally,  the  Company's  systems, which incorporate software and related
consulting  services,  generate  information to assist providers concurrently in
making  informed clinical resource utilization and patient care decisions. These
clinical  decision  support  systems  are  designed  to  enable  providers  to:

     -  Determine  appropriate  cost-effective  treatment  plans  for individual
patients.

     -  Compare  actual  individual patient outcomes with both predicted patient
outcomes  and  statistically  relevant  similar  hospital, regional and national
norms  to  identify  areas  for  improvement.

     -  Analyze  the  performance  of  physicians  by  using  clinically  based,
peer-reviewed,  severity-adjustment  methods.

     -  Analyze  and  measure quantifiable improvements in the clinical and cost
outcomes  of  specified  groups  of  patients.

     - Plan staffing, number of beds and bed mix given the severity-adjusted mix
of  patients  in  an  intensive  care  unit.

     APACHE's  products  and  services  are  differentiated  from  many  other
healthcare  decision  support  systems  in  the  following  important  ways:

     -  Detailed Clinical Data.  APACHE's products and services utilize detailed
clinical  data on a variety of health parameters and outcomes data. In addition,
APACHE's  products  and  services  utilize administrative and utilization data.

     - Patient-specific, Severity-adjusted Data.  APACHE's products and services
utilize  clinical,  demographic  and  financial data for individual patients, in
addition  to  patient  groups.  APACHE's  methodologies  are  designed  to
severity-adjust these data to enable the assessment of the overall health status
of  the  patient.  Severity adjustment is a technique for weighting the relative
factors  affecting  the  degree of illness of a patient. Physicians use APACHE's
patient-specific clinical decision support systems to develop individual patient
care  plans  incorporating  APACHE's  severity-adjusted  outcomes  predictions.


                                        2

     -  Concurrent,  Predictive  Outcomes Information.  APACHE's systems support
physician decision making by providing outcomes information in three timeframes:
(i)  predictions of the patient's outcomes (e.g., mortality, adverse occurrences
and  length  of  stay);  (ii)  current  information, such as the patient's daily
health  status;  and  (iii)  historical  or  retrospective information about the
patient  or  groups  of  similar patients. In contrast to retrospective systems,
APACHE's  ability  to  provide  concurrent information permits the generation of
predictive  information during the course of a patient's care, thereby enhancing
a  physician's  ability  to  direct  treatment resources as the patient's health
status  changes.

     - High-risk, High-cost Patient Focus.  Unlike decision support systems that
focus  primarily on general hospital patients, APACHE's systems are specifically
designed  to  help  predict  outcomes for high-risk, high-cost patients, such as
critical  care patients. These patients typically represent a disproportionately
large  share  of  hospital  costs.

     APACHE's  solutions  are  derived  from  the  Company's  clinical  outcomes
methodologies  and  proprietary  databases.

     Clinical Outcomes Methodologies.  APACHE's methodologies include algorithms
that  apply  relative weightings to selected physiological variables to define a
patient's health status. APACHE's methods of measuring variations in a patient's
health  status  and  outcomes  in critical care have been utilized in connection
with more than 1,600 peer-reviewed articles in professional journals. APACHE has
acquired  rights  to  and  refined  these  methodologies,  which were originally
developed  by  leading  academic  medical  centers such as The George Washington
University  Hospital  and  Dartmouth-Hitchcock  Medical  Center.

     Proprietary  Databases.  The  Company's databases include data on a variety
of  health  parameters,  such as vital signs, laboratory results and measures of
physiological  function,  as well as outcomes data, such as adverse occurrences,
morbidity  and  mortality.  The  databases  contain  information  from more than
1,500,000  patients, most of whom are high-risk, high-cost patients. The Company
created,  and  continues  to  refine,  the  critical  care  and  sub-acute  care
databases.  APACHE  acquired  rights  to  its  cardiovascular  care, acute care,
HIV/AIDS,  and neonatal databases. In cardiovascular and acute care, APACHE also
acquired  the  rights  to  related  methodologies.  APACHE's  databases  are
periodically  updated  with  patient  data  from  customers  as  well as special
studies,  with  the  goal  of ensuring that the databases reflect the results of
current  medical  practice  on  a  national  basis.

     APACHE's  products  and  services  are  currently  focused  on  coverage of
patients  in the critical, acute, sub-acute, and cardiovascular care categories.
The  Company  also  currently  offers  products, consulting services, and health
outcomes research in HIV/AIDS and is considering adding additional categories in
the  future.

CUSTOMER  TRAINING  AND  SUPPORT

     The  Company provides standard and custom training programs to customers on
the use of APACHE's products. In addition to direct user training, APACHE trains
customer  representatives  to  train  their  own  personnel.  Following  initial
standard  training,  the Company provides customer software support, a toll-free
customer  service  hotline and periodic standard product upgrades. Customers pay
an  annual  software  support  service  fee  approximately  equal  to 18% of the
software  license  portion  of  the  product  price for ongoing software support
services.

CUSTOMERS

     APACHE  currently  markets  its  products  and  services  to three types of
customers:  healthcare  providers,  healthcare  suppliers,  and  government. The
Company's  healthcare  customers  include  hospital-based  integrated  delivery
systems, academic and teaching hospitals and individual not-for-profit hospitals
within  integrated  systems.  In  addition,  APACHE's provider customers include
Vencor,  Inc.,  a  multi-facility  provider  of long-term healthcare and medical
coalitions.  The  Company's  healthcare  supplier  customers  are pharmaceutical
manufacturers,  biotechnology  firms,  and medical device companies. The Company
also  offers health outcomes research and database services to federal and state
government  agencies  such  as  The  Centers  for  Disease  Control  ("CDC").

     No  customer accounted for more than 10% of the Company's revenue in 1999.

TECHNOLOGY  AND  PRODUCT  DEVELOPMENT

     The  Company  believes  that the timely development of new products and the
enhancement  of existing product lines are important to continue to build on its
competitive position. APACHE releases enhancements, standard upgrades, revisions
and  new  products  on  an  ongoing  basis.


                                        5
<PAGE>
     The Company's development strategy includes products and services that: (i)
leverage  APACHE's  databases;  (ii)  increase  the  functionality  of  current
products;  and  (iii)  expand coverage along the continuum of care to additional
disease  or  procedure  groups.  The  Company's  major  products  are  based  on
internally  developed software and analytical studies. Late in 1998, the Company
began  selling  turnkey  systems  including  computer  hardware sourced from the
manufacturers.  The  software  products  are generally built on a client/ server
architecture that includes UNIX or Windows NT-based servers, Windows 95/NT-based
PCs,  graphical  user  interfaces  and  other  software developed by third-party
vendors.  The  server  hosts  a  comprehensive  data repository using relational
database  management  system  ("RDBMS")  and  multidimensional database ("MDDB")
technologies.  The  server  can  interface  with  hospital  systems, such as the
laboratory,  admission  and  bedside charting systems, and uses an open standard
HIE,  Inc.  interface  engine  to  support  the current versions of the industry
standard  Health  Level  7  information  exchange  protocols.

     In 1998, the Company commissioned an independent third party to undertake a
feasibility  study  concerning  development  by  the  Company of an architecture
pursuant  to  which  the  Company  could provide its clients with Internet-based
access  to  certain  of  the Company's products.  In 1999, the Company proceeded
with  development  of Internet based decision support products and services. The
Company  has  implemented  a  functional fault  tolerant  Internet  architecture
Residing  on computer platforms from Data General, a division of EMC Corporation
("DG"),  and  operating  via  a  backbone  provided  by  UUNET, an MCI Worldcom
Company.  The Company  intends  to  introduce  the  first  such  Internet  based
decision  support  applications  in  the  year  2000.

SALES  AND  MARKETING

     The Company currently markets and sells its products and services through a
direct  sales  force.  APACHE believes that the most effective use of its direct
sales  force  is  in marketing the CCS and Best Care program to hospital systems
and  individual  hospitals  with  200  or  more  licensed  beds.

     During  1999,  the  Company  continued  its  marketing  agreement  with  an
affiliate  of  Premier,  Inc.,  which  provides  buying  services  to a group of
approximately  1,800 hospitals. Pursuant to the agreement, the Premier affiliate
has designated the Company as the exclusive supplier to the hospitals purchasing
through  the  Premier buying group of clinically-based outcomes data systems for
high-risk,  high-cost patients, including critical care, cardiovascular care and
medical-surgical  care  patients,  through  December  31,  1999.

     Also  during  1999,  the  Company continued the APACHE partnership program.
This  is a risk sharing system partnership, including consulting services, which
allows the client access to the APACHE Critical Care system benefits without the
need  for  outright  purchase of the system. The Company believes that this risk
sharing  approach  has  been well received by prospective partnership clients in
1999  resulting in several new installations based on the partnership approach.

     APACHE's  consulting  services  are  marketed both as part of the Best Care
program  and  separately  by  the  Company's  consultants.  The Company's Health
Outcomes  Research  and  strategic  consulting  services  are  marketed  by  the
developers  of  those  programs  and  other  Company  professionals  directly to
suppliers  and  providers.

PROPRIETARY  RIGHTS

     The  Company  continues  to make significant investments in the development
and  maintenance  of  its  risk-adjustment  methodologies  and  its  proprietary
clinical and financial databases and software. The clinical databases maintained
by  the Company include a highly detailed level of clinical information that the
Company  believes  provides  a  key  advantage  over  competing decision support
systems  when  combined  with APACHE's value-added clinical software. APACHE has
multi-disciplinary  clinical  and database management personnel that audit, edit
and  standardize data from customers and other sources to maintain statistically
relevant  databases.  The  Company  believes  that  the  sophistication  of  its
risk-adjustment  methodologies,  the  size  and  richness  of  its corresponding
proprietary databases and the usefulness of its software provide better outcomes
measurements  and  utilization  control  than  competitive  systems.

     The  Company depends upon a combination of trade secret and copyright laws,
nondisclosure and other contractual provisions and technical measures to protect
its proprietary rights in its methodologies, databases and software. The Company
has  not  filed any patent applications covering its methodologies and software.
The  Company  distributes  its  software  products  under  agreements that grant
customers  non-exclusive  licenses  and contain terms and conditions restricting
the  disclosure  and  use  of APACHE's databases or software and prohibiting the
unauthorized  reproduction  or  transfer  of  its  products. In addition, APACHE
attempts  to  protect  the  secrecy of its proprietary databases and other trade
secrets  and  proprietary  information  through  agreements  with  employees and
consultants.  Portions  of  APACHE's  methodologies  are,  however, available in
scientific  literature  and  bona  fide  researchers have been granted access to
portions  of  APACHE's  databases  for peer review and other research purposes.


                                        6
<PAGE>
     The  Company  also seeks to protect the source code of its software and its
databases  as  trade  secrets and under copyright law. The Company has copyright
registrations  for  certain  of  its  software,  user manuals and databases. The
copyright  protection  accorded  to databases, however, is fairly limited. While
the  arrangement and selection of data are protectable, the actual data are not,
and  others  are  free  to  attempt  to  create databases  that perform the same
function.  The Company  believes,  however,  that  the  creation  of   competing
databases would be very  time consuming  and  costly.  In addition, the  Company
expects  that the pending  implementation  of  HIPAA,  as  defined  below, could
raise an additional barrier  to  entry  for  prospective  competitors.


     "APACHE"  is  registered  as  a trademark and/or service mark in connection
with  certain  of  the  Company's  current  products  and services in the United
States,  Australia,  the  Benelux  countries,  Brazil,  Canada, France, Germany,
Italy, Sweden and the United Kingdom. The Company believes that it has developed
substantial  goodwill  in  connection  with  its mark as an indicator of quality
products  and  services.

     The  Company believes that, aside from the various legal protections of its
proprietary  information and technologies, factors such as the technological and
creative  skills  of  its  personnel  and  its  reliable product maintenance and
support  are  integral  to  establishing  and  maintaining a leadership position
within  the healthcare industry. In addition, although the Company believes that
its products do not infringe upon the proprietary rights of third parties, there
can  be  no  assurance  that  third  parties will not assert infringement claims
against the Company in the future or that a license or similar agreement will be
available  on reasonable terms in the event of an unfavorable ruling on any such
claim.

COMPETITION

     The  market  for  healthcare  information  systems  and  services is highly
competitive  and  rapidly  changing.  The  Company  believes  that the principal
competitive  factors  for  clinical  outcomes systems and services are achieving
documented success in impacting cost and quality and demonstrating an attractive
payback on the decision support system investment. Other differentiating factors
include  quality  and  depth  of the underlying clinical outcomes databases, the
proprietary nature of methodologies, databases and technical resources, customer
service  and  support,  compatibility  with  the customer's existing information
systems,  potential  for  product  enhancement, vendor reputation, price and the
effectiveness  of  marketing  and  sales  efforts.

     The  Company's   competitors  include  other  companies  that  collect  and
distribute  healthcare data, such as HCIA-Sachs  Inc., MIDS, Inc.,  CareScience,
Inc., HBS  International,  The MEDSTAT  Group,  MEDai,  Inc. and Iameter.  Other
companies   that  provide   healthcare   information   systems   include  Cerner
Corporation,   McKessonHBOC,   Shared  Medical  Systems  Corporation,   Eclipsys
Corporation,  IDX Systems  Corporation,  VitalCom  Inc. and Medical  Information
Technology,  Inc.  A number  of these  companies  both  compete  for the  health
system's  information  investment dollars and represent  potentially  attractive
distribution  channels  for the  Company.  The  Company's  products and services
differ from the products and services  offered by  competitors by the clinically
data-based,  acquity  adjusted focus on both high-risk,  high-cost  patients for
both  concurrent  and  predictive  outcomes  information.  Many of the Company's
competitors  and  potential  competitors  may have  greater  financial,  product
development,  technical and marketing resources than the Company,  and currently
have, or may develop or acquire,  substantial  installed  customer  bases in the
healthcare industry.  The Company also faces potential competition from existing
and new industry associations, such as the Project Impact initiative,  sponsored
by the Society for Critical Care  Medicine,  who are  attempting to collect data
from their member physicians in a voluntary association effort to build registry
services and  comparative  reports.  As the market for decision  support systems
develops,  additional  competitors  may enter the  market  and  competition  may
intensify.  While  the  Company  believes  that  it  continues  to  successfully
differentiate  itself from  competitors,  there can be no assurance  that future
competition would not have a material adverse effect on the Company.

GOVERNMENT  REGULATION

     The  confidentiality  of  patient records and the circumstances under which
such  records  may  be released is subject to substantial regulation under state
and  federal  laws  and  regulations.  To  protect patient confidentiality, data
entries  to  APACHE's  databases  omit  any patient identifiers, including name,
address,  hospital  and  physician.  The  Company  believes  that  in  1999  its
procedures  complied  with  the  then current laws and regulations regarding the
collection  of  patient data in substantially all jurisdictions, but regulations
governing  patient  confidentiality  rights  are  evolving rapidly and are often
difficult  to  apply.  Additional  legislation  governing  the  dissemination of
medical  record  information  has  been  proposed  at both the state and federal
level.  This  legislation  may  require holders of such information to implement
security  measures  that may be of substantial cost to the Company. There can be
no assurance that changes to state or federal laws would not materially restrict
the  ability  of  the  Company  to  obtain  patient information originating from
records.


                                        7
<PAGE>
     Patient Data and  Confidentiality:  The Health  Insurance  Portability  and
Accountability  Act of  1996  ("HIPAA"  or the  "Act")  mandates  administrative
simplification  by  requiring  certain  standardized   information  transactions
through the use of uniform elements. To date, proposed regulations under the Act
have been issued for public comment but have not yet been finalized. The Act and
the proposed  regulations  would impose a number of  stringent  requirements  on
health  plans,  health care  providers,  health care  clearinghouses,  and their
"business  partners." In particular,  the regulations mandate the use of certain
safeguards to secure the  confidentiality  of electronic  medical  records.  The
regulations  implement required security standards for all "health  information"
pertaining to an individual that is electronically  maintained or electronically
transmitted.  The basic standards require entities to (1) assess their risks and
vulnerabilities,  (2) maintain appropriate  security measures,  and (3) document
these methods. At a minimum, the methods must include administrative procedures,
physical  safeguards,   technical  security  services,  and  technical  security
mechanisms  to  guard  data  integrity,  confidentiality,  and  availability  of
confidential patient information.

     The  proposed regulations also impose additional restrictions on the use of
an  individual's health information. Under the regulations, health plans, health
care  providers,  health  care  clearinghouses and their business partners must:
(i)  not  use or disclose an individual's "protected health information" without
first  obtaining  an  authorization  from that individual, except for treatment,
payment,  or  health  care  operations,  (ii)  provide individuals with specific
rights  relating to obtaining and correcting their protected health information,
and  (iii)  adhere  to the administrative requirements of the regulations, which
include  designating  a privacy official; creating a contact person or office to
handle  complaints;  training  employees  regarding  the  entity's  policies and
procedures;  implementing  appropriate  administrative,  technical, and physical
safeguards  to  protect  protected  health  information; providing a process for
individuals  to make complaints; and documenting compliance with the regulations
through  policies  and  procedures.

     The requirements of the Act and regulations will not be effective until two
years after the  regulations are finalized,  which is not currently  expected to
occur until the summer of 2000.  To the extent that  uncertainty  regarding  the
application  of the Act  impacts our  customers'  purchasing  decisions  and the
Company incurs the incremental cost for system modifications  required to comply
with the Act, the Act may have a material adverse effect on the Company  and its
operations  beginning  in 2000 and  continuing  for the next few  years.  To the
extent  that the  Company  has access to  confidential  patient  information  as
defined under the Act and  regulations,  it will be required to be in compliance
with such  regulations  if and when the Act goes into  effect.  The  Company  is
closely monitoring the status of the proposed regulations and intends be in full
compliance with them when they become final and effective.  However,  compliance
cannot be  assured  and the cost of  achieving  compliance  is not known at this
time.

     Patient Safety: In November of 1999, the Institute of Medicine (IOM) of the
National  Academies  issued  a  report  compiling  findings  of major studies of
medical  errors  that  pointed  to  high  rates  of  medical errors resulting in
deaths,  permanent disability, and unnecessary suffering. The document also laid
out  suggestions  for  a  comprehensive  strategy  for  government,  industry,
consumers, and health providers to reduce medical errors, and called on Congress
to  create  a  national  patient  safety center to develop new tools and systems
needed  to  address  these  problems.

     In  response  to  this  study, the Clinton Administration in February 2000,
announced  several  new  edicts  not  requiring Congressional action, including:
immediate  mandatory  reporting  requirement  for  the  500  Defense
Department-administered  hospitals,  a  Health  Care  Financing  Administration
requirement  for  error  reduction plans  in all   hospitals that participate in
Medicare,  and  giving  the Food and Drug Administration one year to develop new
standards  to  help prevent medical mistakes caused by sound-alike drug names or
look-alike  products.

     It  is  not known what impact, if any, final regulations or legislation may
have  on  the  Company.

      Other  Government  Regulation:  The  healthcare  industry  is  subject  to
changing  political,  economic  and  regulatory  influences  that may affect the
procurement practices and operations of healthcare industry participants. During
the past several years, government regulation of reimbursement rates and capital
expenditures  in  the United States healthcare industry has increased. Lawmakers
continue  to  propose  programs  to  reform the United States healthcare system,
which  may contain proposals to increase governmental involvement in healthcare,
lower reimbursement rates and otherwise change the operating environment for the
Company's  customers.  Healthcare  industry  participants  may  react  to  these
proposals  by  curtailing or deferring investments, including investments in the
Company's products. The Company cannot predict what impact, if any, such factors
may  have  on  its business, financial condition and results of operations or on
the  price  of  the  Common  Stock.

     Certain  products, including software applications, intended for use in the
diagnosis  of disease or other conditions, or in the cure, treatment, mitigation
or  prevention  of  disease,  are  subject  to  regulation  by the Food and Drug
Administration  ("FDA")  under  the  Federal Food, Drug and Cosmetic Act of 1938
("FDCA"),  as amended. The FDCA imposes substantial regulatory controls over the
manufacturing, testing, labeling, sale, distribution, marketing and promotion of


                                        8
<PAGE>
medical  devices  and  other  related  activities. These regulatory controls can
include,  for example, compliance with the following: manufacturer establishment
registration  and  device  listing;  current  good  manufacturing  practices;
completion  of  premarket  notification  or  premarket  approval; medical device
adverse event reporting; and general controls over misbranding and adulteration.
Violations  of  the  FDCA can result in severe criminal and civil penalties, and
other  sanctions, including, but not limited to, product seizure, recall, repair
or refund orders, withdrawal or denial of premarket notifications and approvals,
and  denial  or  suspension  of  government  contracts,  and injunctions against
unlawful  product  manufacture,  labeling,  promotion, and distribution or other
activities.

     In  its  1989  Policy  for  the  Regulation of Computer Products (the "1989
Policy  Statement"),  the FDA stated that it intended to exempt certain clinical
decision  support  software products from a number of regulatory controls. Under
the  1989  Policy  Statement,  the  FDA  stated  that  it intended to promulgate
regulations  exempting  decision  support software products that are intended to
involve  "competent  human intervention before any impact on human health occurs
(e.g., where clinical judgment and experience can be used to check and interpret
a  system's  output)"  from  the  following controls: manufacturer establishment
registration and device listing, premarket notification, and compliance with the
medical device reporting and current good manufacturing practice regulations. In
the  1989 Policy Statement, the FDA stated that until it promulgated regulations
implementing the exemptions, manufacturers of eligible decision support software
products  would  not  be  required  to  comply  with  those  controls.

     Since  issuing  the  1989 Policy Statement, the FDA has neither promulgated
the  exemption  regulations  discussed in the 1989 Policy Statement nor actively
sought  to  enforce  compliance  with  the  controls  discussed  in  such Policy
Statement.  Furthermore,  the  FDA  has referred to the 1989 Policy Statement in
official  presentations  regarding  software  regulation  and  in  decisions and
opinions  regarding the regulatory status of various products. Over the last few
years,  however,  the  FDA  has stated that it intends to revise the 1989 Policy
Statement  and  to  base  exemptions  from  regulatory  controls, if any, upon a
product  specific  "risk factor" analysis. The risk factors the FDA has proposed
using  include:  (i) seriousness of the disease to be diagnosed or treated; (ii)
time  frame  for use of the information; (iii) concordance with accepted medical
practice;  (iv)  format  of data and its presentation; (v) individualized versus
aggregate  patient  care recommendations; and (vi) clarity of algorithms used in
the  software.  Given  the  formative state of the FDA's evaluation and possible
revision  of  the  1989  Policy  Statement,  there can be no assurance as to the
criteria  or  application  of  such  revisions,  if  any.

     The  Company's  products  are  intended  to  assist healthcare providers in
analyzing  economic  and  quality  data  related  to  patient  care and expected
outcomes  in  order  to  maximize  or  monitor the cost-effectiveness of general
treatment  plans  and  practice  guidelines.  These products are not intended to
provide  specific  diagnostic  data  or  results  or  affect the use of specific
therapeutic  interventions.  As such, the Company believes that its products are
not  medical  devices  under the FDCA and, thus, are not subject to the controls
imposed  on  manufacturers of medical devices. The Company further believes that
to  the extent that its products are determined to be medical devices, they fall
within  the  exemptions for decision support systems provided by the 1989 Policy
Statement. The Company has not taken action to comply with the requirements that
would  otherwise  apply  if  the  Company's  products  were  non-exempt  medical
devices.

     Since  1992, the Company's products have been widely marketed and have been
reviewed  or  evaluated in the medical literature. The FDA has neither requested
that  the Company take any action to comply with any controls under the FDCA nor
notified  the  Company  that it is not in compliance with any such controls. The
Company  is  not aware of the FDA requiring other developers of similar products
to  take  any  action  to comply with any controls under the FDCA, or of the FDA
notifying such developers that they are not in compliance with any such controls
with  respect  to  those  similar  products.

     Nevertheless,  there  can be no assurance that the FDA will not make such a
request  or  take  other action to require the Company to comply with any or all
current  or  future  controls  applicable  to  medical  devices. There can be no
assurance  that,  if  such  a  request were made or other action were taken, the
Company  could  comply  in  a  timely  manner, if at all, or that any failure to
comply  would  not  have  a  material  adverse effect on the Company's business,
financial  condition, results of operations or on the price of the Common Stock,
or  that  the  Company  would not be subjected to significant penalties or other
sanctions.  There  can  be no assurance that the FDA will continue any or all of
the  exemptions  provided  in  the 1989 Policy Statement, or in a revised policy
statement,  if  any,  or  that  the  FDA  will  promulgate  regulations formally
implementing  such  exemptions.  There can be no assurance that the FDA will not
now  or  in  the future make determinations that the Company's current or future
products  are  medical devices subject to FDA regulations and are ineligible for
the  exemptions from those regulations. If the FDA made such determinations, the
Company would not be able to market its products without obtaining FDA clearance
of  premarket  notifications, or FDA approval of premarket approval applications
submitted  by the Company. The regulatory process can be lengthy, expensive, and
uncertain;  securing  FDA  clearances or approvals may require the submission of
extensive  non-clinical and clinical safety and effectiveness data together with
other  supporting  information to the FDA; and there could be no assurance as to
when  if ever the FDA clearances or approvals would be obtained. There can be no
assurance  that the Company's current or future products will qualify for future
exemptions,  if any, nor can there be any assurance that any future requirements
will  not  have  a  material adverse effect on the Company's business, financial
condition  and  results  of  operations.

ITEM 7.  MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS
OF  OPERATIONS

OVERVIEW

     Consistent  with the change in business strategy developed during the third
quarter  of  1997,  throughout  1999 the Company continued to manage and contain
costs,  conserve  cash  and  further  intensified  the  Company's  focus  on the
high-risk,  high-cost  patient  market  particularly  in critical care medicine.

     During the year, the Company launched its Internet  healthcare  initiative,
APACHE  2000.  The  initiative  is  designed  to  position  the  Company  as  an
application service provider ("ASP") in the field of  Internet-based  healthcare
decision support.  The Company  will  develop  Internet  versions  of  both  new
decision support applications as well as selected existing  applications  on  DG
platforms.  The roll out of these  Internet   products   is  expected  to  begin
in 2000.  The  Company estimates  the cost of the  development  of APACHE   2000
to be in excess of $1.5 million.  The Company is now in the product introduction
phases of development and is not currently in a position  to  fully  assess  the
financial or other impacton the Company's operations.

     During  1999  the  Company's  Internet project and accompanying partnership
discussions  have  remained  on budget and on schedule resulting in a functional
fault  tolerant  Internet  architecture  running  on  DG  computer platforms and
currently  serving as a test bed for further development of various critical and
acute  care,  neonatal  and  cardiovascular  decision  support  applications.

     The  Company  is a Value Added Reseller of both  DG  and  Sun  Microsystems
computer hardware related  to  its  CCS product.  In 1999 the  sale  of  turnkey
systems  provided  the  company  with  incremental  sources  of  revenue  from
hardware  sales  and, accordingly,  incremental  sources of contribution margin.
The sales of this computer  hardware had  a  material  affect  on  the Company's
order rates throughout 1999.

1999  Compared  to  1998

     Revenue.  Revenue  for 1999 increased 18% to $12 million from $10.2 million
in  the  prior  year  period.  Systems  revenue  for 1999 increased 112% to $5.0
million  from  $2.4  in  the  prior  year period.  Increased Systems revenue was
primarily  related  to  the  delivery  and  implementation of the new CCS to new
customers  and  the  sale of this system to existing customers.  Systems revenue
included  revenue  related  to  the accompanying sales of associated third party
hardware  and  software.  Support  revenue for 1999 increased 9% to $2.3 million
from  $2.1  million in the prior year period, due to contractual price increases
and  an  increase  in  the  number  of  clients utilizing the Company's systems.
Professional  services  revenue for 1999 declined 19% to $4.7 million from $5.7;
the  decline  was  due,  in  part,  to  a  decrease  in Health Outcomes Research
revenues following the bankruptcy of one of  the  Company's  largest  customers.
Consulting Services  revenue  also  declined;  this  was primarily attributed to
customers' concerns  over  addressing  their  own Y2K issues  and  the impact of
the  Balanced  Budget  Act  on  their  operations.

     Cost  of  Operations.  Cost  of  operations  for 1999 decreased 28% to $3.1
million from  $4.4  million  in  the  prior  year  period. This decrease was due
to the Company's continued corporate reorganization  resulting  in  productivity
improvements  and  related  decreases  in  costs associated with the delivery of
systems,  support  and  professional  services.  Cost  of  operations  for  1999
decreased  to  26%  of  revenue  from  43%  in the prior year period, due to the
reasons  mentioned here and the increase in revenue during the same period. Cost
of  operations consists primarily of personnel costs, costs of media, production
manuals,  telephone  support,  third  party  equipment, licenses sold, and other
direct  costs  related  to providing systems, support and professional services.

     Research  and  Development.  Research  and  development  expenses  for 1999
decreased  47%  to  $701,000  from  $1.3  million  in the prior year period, due
primarily  to  a decrease in staffing requirements related to the development of
new,  non-core, peripheral products and services that the Company had previously
discontinued.  During  1999,  $501,000  of  software  development  costs  were
capitalized,  compared  to  $556,000  in  the  prior  year  period. Research and
development  expenses  for 1999 decreased to 6% of revenue from 13% in the prior
year  period,  due to decreased staffing and other costs as well as the increase
in  revenue  during  the  same  period.

     Selling,  General  and Administrative.  Selling, general and administrative
expenses  for  1999 decreased 13% to $7.1 million from $8.1 million in the prior
year  period.  This  decrease was due primarily to a decrease in overall general
and  administrative  expenses  including  decreases  in  staffing and consulting
expenses.  The  reduction  in general and administrative expenses were partially
offset  by  increases  in  costs   associated   with   sales  and  marketing.
Selling,  general  and  administrative  expenses  for  1999  decreased to 59% of
revenue  from  80%  for  the prior year period, due primarily to the increase in
revenue  during  the  same  period.

     Other  Income  (Expense).  Other  income decreased from $441,000 in 1998 to
$296,000  in  1999.  This  decrease  was  attributable to a decrease in interest
income  related  to  the  decrease  in  the  amount  of  short-term investments.

     Taxes.  The Company has not incurred income taxes as a result of generating
net  operating  losses  in  prior  years  for  tax  purposes.

1998  Compared  to  1997

     Revenue.  Revenue for 1998 increased 18% to $10.2 million from $8.6 million
in  the  prior  year  period.  Systems  revenue  for 1998 increased 155% to $2.4
million  from  $935,000  in the prior year period. Increased Systems revenue was
primarily  related to the delivery of the CCS in early 1998. Support revenue for
1998  increased  8%  to $2.1 million from $2.0 million in the prior year period,
due  to  contractual  price  increases  and an increase in the number of clients
utilizing the Company's systems. Professional services revenue for 1998 remained
constant  at  $5.7  million.

     Cost  of  Operations.  Cost  of  operations  for 1998 decreased 19% to $4.4
million  from  $5.4  million  in the prior year period. This decrease was due to
process  improvements relating to systems implementations, support, and software
engineering  and  resulting  decreases  in  staffing  requirements,  third party
licenses  fees  for  systems and related products, services that the Company has
discontinued  or  postponed,  the development of certain other products, and the
decision  to  focus  primarily  on  products  for  critical care patients, which
resulted  in the Company's restructuring charge of $1.6 million during the third
quarter  of  1997.  Cost of operations for 1998 decreased to 43% of revenue from
63% in the prior year period, due to the reasons mentioned here and the increase
in  revenue.  Cost of operations consists primarily of personnel costs, costs of
media,  production  manuals,  telephone support, third party equipment, licenses
sold,  and  other  direct  costs  related  to  providing  systems,  support  and
professional  services.

     Research  and  Development.  Research  and  development  expenses  for 1998
decreased  51%  to  $1.3 million from $2.7 million in the prior year period, due
primarily  to  a decrease in staffing requirements related to the development of
new  products  and  services that the Company has discontinued or postponed as a
result of the Company's restructuring during third quarter of 1997. During 1998,
$556,000  of product development costs were capitalized, compared to $308,000 in
the  prior  year period. Research and development expenses for 1998 decreased to
13%  of  revenue from 31% in the prior year period, due to decreased staffing as
well  as  the  increase  in  revenue  from  1997  to  1998.

     Selling,  General  and Administrative.  Selling, general and administrative
expenses  for  1998  decreased 42% to $8.1 million from $14 million in the prior
year  period.  This  decrease  was due primarily to a decrease in overhead costs
associated  with  the  Company's restructuring during the third quarter of 1997,
the  elimination  of  a  number  of  outside  consulting  relationships  and the
implementation of enhanced expense controls. Selling, general and administrative
expenses  for  1998  decreased  to  80%  of revenue from 162% for the prior year
period,  due  primarily  to  the  same  factors  as  noted  above.

     Other  Income  (Expense).  Other  income decreased from $825,000 in 1997 to
$441,000  for  1998.  This  decrease  was attributable to a decrease in interest
income  related  to  the  decrease  in  the  amount  of  short-term investments.

     Taxes.  The Company has not incurred income taxes as a result of generating
net  operating  losses  for  tax  purposes.

     In addition, the Company's quarterly results have been, and may continue to
be,  affected  by  supplier  and  provider  budgeting  practices that cause many
discretionary  purchase  decisions  to  be  made before certain quarter and year
ends.  The  timing  of  quarterly revenue is also affected by the ability of the
Company to perform on its contracts, which is subject to the availability of the
client  personnel  as  well  as  the  availability  of  the Company's personnel.
Although  the  Company has not historically experienced any material seasonality
in  its  operating results, the Company could experience such seasonality in the
future,  which  could  cause  fluctuations  in  the Company's quarterly results.

LIQUIDITY  AND  CAPITAL  RESOURCES

     Until  1999  the  Company  had  funded its operations primarily through its
initial  public offering of the Company's Common Stock in July 1996. During 1999
the  Company's  operating activities generated a positive cash flow. At December
31,  1999,  the Company had cash and cash equivalents and short-term investments
of  $6,242,000  representing a decrease of $290,000 from the total of $6,532,000
at  December  31,  1998.

     During  1999,  the  Company's  operating activities generated approximately
$413,000  in  cash.  Net  cash  generated  in 1999 was composed primarily of net
income,  increased  by  depreciation  and  amortization,  decreases  in accounts
receivable  and  accrued  expenses  and  increases  in  deferred  revenues.

     The  Company's  investing  activities  used  cash  of $621,000 in 1999. The
primary use of cash for investing activities was due to  an increase in software
development  costs.

Net cash used by financing activities during 1999 was $130,000 and was primarily
related  to  the  repayment  of  notes  payable  and  capital  leases.

     During  1999 the Company made capital expenditures totaling $72,000.  As of
December 31, 1999, the Company had net working capital of $3.4 million including
cash  and  short-term  investments  in  the  amount  of  $6.2  million.

     The  Company  anticipates  that  funds  generated  from  operations will be
sufficient  to  meet  its  planned  ongoing  operating  and  working  capital
requirements  and  to  finance  planned product development, sales and marketing
activities and capital acquisitions for the next twelve months. Through December
31,  1999,  the  Company  has  incurred  cumulative  net  operating  losses  of
approximately  $40.8 million. There can be no assurance that the Company will be
profitable  in the future or that present capital will be sufficient to fund the
Company's  ongoing  operations.  If  additional  financing  is  required to fund
operations,  there  can  be  no assurance that such financing can be obtained or
obtained  on  terms  acceptable  to  the  Company.

     The  Company  does  not  believe  the impact of inflation has significantly
affected  the  Company's  operations.

YEAR  2000  COMPLIANCE

     During  1999  the  Company completed required modifications to its critical
systems  and  applications  relating  to  year 2000 issues.  The majority of the
Company's  efforts  regarding  Year  2000  readiness  focused  on  the Company's
products,  including  software  applications,  operating  systems,  relational
database  management  systems,  tools  and  utilities  sold  to  clients.  The
assessments  indicated that the version of the Company's Medical Cost Management
Program  ("MCMP") product, an application using UNIX based terminals/clients and
UNIX  based  servers  requiring  stand  alone  equipment, its operating systems,
database  releases  and relational database management systems, that was sold to
customers  prior  to  1998,  was  not Year 2000 ready.  The Company accordingly,
focused  its  attention  on  developing  and ensuring Y2K compliance of its next
generation  CCS  product.  As a result, the CCS application, hardware, operating
systems  and  relational database management system release, tools and utilities
are Year 2000 ready.  The CCS product also includes significant new features and
enhancements.  The  CCS  product  utilizes  industry standard operating systems,
tools  and  utilities  and  operates  on a PC based client/UNIX server platform,
supporting  Windows  95/NT/98.

     As  the  existing  MCMP  product  operating  system and relational database
management  system  releases could not be confirmed Year 2000 ready, the Company
discontinued  support  of  the  MCMP  product beyond December 1999.  The Company
offered  existing  customers  the  ability  to migrate to the new CCS product on
favorable  terms.  A  majority  of the clients using the old UNIX version of the
MCMP  product  have  migrated  to  the  new  CCS  product.  The  remainder  have
discontinued  use  of  the  existing product.  The favorable terms and migration
services  offered  to  existing  customers to encourage migration to the new CCS
product  did  not  have  a  material  negative  impact  on  the Company's future
operating  results  or  financial  position.  The  fact  that  a majority of the
Company's  existing  customers made the decision to move on to the new CCS has a
positive  material  impact on the Company's 1999 operating results and financial
position.


                                       15

     The  renovation  and  implementation  is  complete  for  two other software
applications,  the  Acute  Care  Voyager+ and the HIV Manager products, that the
Company  sold  to its clients.  Other software applications products sold by the
Company  have  been  renovated  and  where  necessary,  the  changes  have  been
implemented  to  delivery  Year  2000  ready  products.

      The  Company  also  completed  its  survey of its significant suppliers to
assess its vulnerability if these companies were to fail to remediate their year
2000  issues.  The  responses received indicated that these suppliers were aware
of  the year 2000 issue and were implementing the necessary changes prior to the
end  of  calendar  year  1999.  The Company also formulated contingency plans to
ensure that business-critical processes were protected from disruption and would
continue  to  function  during  and  after  the year 2000 and to ensure that the
ability  to produce an acceptable level of products and services was safeguarded
in the event of failures of external systems and services.  The Company incurred
approximately  $990,000  of incremental costs in  connection  with  identifying,
evaluating and remediating  year  2000  issues.  These  costs  were  expensed as
incurred.

     The  Company  experienced  no material or adverse effects from the calendar
change  to  the  year  2000  or  from  the leap year that occurred in 2000.  The
Company  has  not been notified of any disruptions to or failures in the systems
of  any  of  its  suppliers.

     The  Company  will  continue to monitor the information and non-information
technology  systems  and  those  of third parties with whom the Company conducts
business  throughout  the  year  2000 to ensure that any latent year 2000 issues
that  may  arise  are  addressed  promptly.  Although  we  do not anticipate any
additional  expenditures relating to year 2000 compliance, we cannot provide any
assurance  as  to  the  magnitude of any future costs until significant time has
passed.

     This  section captioned "Year 2000 Compliance," as well as other statements
herein  or  otherwise relating to the Year 2000 issues, are "Year 2000 Readiness
Disclosures"  pursuant  to  the  "Year 2000 Information and Readiness Disclosure
Act."

NEW  ACCOUNTING  PRONOUNCEMENTS


     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.  SOP  97-2  is effective for revenue transactions
entered  into  by the Company in fiscal years beginning after December 31, 1997.
The  Company  has  adopted SOP 97-2 and it did not have a material impact on the
financial statements of the Company. In March 1998, AcSEC issued SOP 98-4, which
defers  for  one  year  the implementation of certain provision of SOP 97-2. The
issuance  of  SOP 98-4 had no effect on the Company. In December 1998, the AICPA
issued  SOP  98-9,  which extends the deferral date of implementation of certain
provisions  of  SOP 97-2 to 2000 and amends the method of revenue recognition in
some  circumstances. The  adoption of this SOP did not have a significant effect
on  its  results  of  operations  or  financial  position.

SAFE  HARBOR  FOR  FORWARD-LOOKING  STATEMENTS

     Statements   in  this   filing   which   are  not   historical   facts  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 regarding our expectations,  beliefs, intentions
or future  strategies  that are signified by the words  "expects,""anticipates,"
believes" or similar language. All forward-looking  statements involve risks and
uncertainties.  The  Company  wishes  to  caution  readers  that  the  following
important factors,  among others, in some cases have affected, and in the future

products and services  to  potential  regulatory  changes,  including HIPAA, and
ability  to adapt to economic, political and regulatory conditions affecting the
healthcare  industry.

     The  Company's  quarterly  revenues  and  operating  results  have  varied
significantly  in  the  past  and are likely to continue to vary from quarter to
quarter in the future. Quarterly revenues and operating results may fluctuate as
a result of a variety of factors, including: the Company's relatively long sales
cycle;  variable  customer  demand for its products and services; changes in the
Company's  product  mix and the timing and relative prices of product sales; the
loss  of  customers  due to consolidation in the healthcare industry; changes in
customer  budgets;  investments  by  the Company in marketing or other corporate
resources;  acquisitions of other companies or assets; the timing of new product
introductions  and  enhancements  by the Company and its competitors; changes in
distribution  channels;  sales  and  marketing  promotional activities and trade
shows;  and  general  economic  conditions. Further, due to the relatively fixed
nature  of most of the Company's costs, which primarily include personnel costs,
as  well  as  facilities  costs,  any  unanticipated shortfall in revenue in any
fiscal  quarter  would  have  an  adverse  effect  on  the  Company's results of
operations in that quarter. Accordingly, the Company's operating results for any
particular  quarterly  period  may  not necessarily be indicative of results for
future  periods.

ITEM  7A.-QUANTITATIVE  AND  QUALITATIVE  DISCLOSURES  ABOUT  MARKET  RISK

     The  Company  is  exposed  to  certain  financial  market  risks,  the most
predominate  being fluctuations in interest rates; however, the Company does not
believe  that  it  is  currently  exposed  to  material  financial market risks.

                         REPORT OF INDEPENDENT AUDITORS

Board  of  Directors
APACHE  Medical  Systems,  Inc.

     We  have  audited  the  accompanying  consolidated balance sheets of APACHE
Medical  Systems,  Inc.  as  of  December  31,  1999  and  1998, and the related
consolidated  statements  of operations, stockholders' equity and cash flows for
the  years then ended. Our audits also included the financial statement schedule
listed  in  the  Index  at  Item  14(a)  as of December 31, 1999 and 1998. These
financial  statements  and  schedule  are  the  responsibility  of the Company's
management.  Our  responsibility  is  to  express  an opinion on these financial
statements  and  schedule  based  on  our  audits.

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

     In  our opinion, the financial statements referred to above present fairly,
in  all material respects, the consolidated financial position of APACHE Medical
Systems,  Inc.,  at  December 31, 1999 and 1998, and the consolidated results of
their  operations  and  their cash flows for the years then ended, in conformity
with accounting principles generally accepted in the United States. Also, in our
opinion,  the  related financial statement schedule, when considered in relation
to  the  basic  financial  statements  taken  as a whole, presents fairly in all
material  respects  the  information  set  forth  therein.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
                           DECEMBER 31, 1999 AND 1998

(1)  NATURE  OF  THE  BUSINESS

     APACHE  Medical  Systems, Inc. (the "Company"), a Delaware corporation, was
incorporated  on  September  1,  1987.  The  Company  is  a  leading provider of
clinically based decision support information systems and consulting services to
the healthcare industry. The Company offers healthcare providers and suppliers a
comprehensive  line  of  outcomes-based  products  and  services,  encompassing
software,  hardware,  and  related  consulting  and disease management services.

     Operations  of  the  Company are subject to certain risks and uncertainties
including,  among  others,  uncertainties  relating  to  product  development,
significant operating losses, competition and market acceptance of its products.
The  market  for  the  Company's  healthcare information systems and services is
highly  competitive  and  characterized  by  continued  and  rapid technological
advances and substantial changes. The Company's success is dependent upon market
acceptance of its products in preference to competing products and products that
may  be  developed  by  others.  The  healthcare industry is subject to changing
political,  economic  and  regulatory influences that may affect the procurement
practices  and  operations of the Company's customers. There can be no assurance
that  the  Company's  products  and  services will achieve a sufficient level of
market  acceptance  to  result  in  profitable  operations.

     Through  December  31,  1999,  the  Company  has  incurred  cumulative  net
operating  losses of approximately $40.8 million. There can be no assurance that
the  Company  will  be  profitable in the future or that present capital will be
sufficient  to  fund the Company's ongoing operations. The Company believes that
its  current  operating  funds  will  be  sufficient to meet its planned ongoing
operating  and  working  capital  requirements  and  to  finance planned product
development,  sales  and  marketing activities through the first quarter of year
2001.  If  additional  financing is required to fund operations, there can be no
assurance that such financing can be obtained or obtained on terms acceptable to
the  Company.

(2)  SUMMARY  OF  SIGNIFICANT  ACCOUNTING  POLICIES

Business  combinations

     On  June  2,  1997,  the  Company acquired all the common stock of National
Health  Advisors,  Ltd.  ("NHA") in exchange for 367,569 shares of the Company's
Common Stock. NHA is a healthcare management consulting firm focused on strategy
and  management  support  services  for progressive healthcare organizations and
networks.  The  merger was accounted for as a pooling-of-interests. Accordingly,
the  Company's financial statements have been restated to include the results of
NHA  for  all  periods  presented.

Principles  of  Consolidation  and  Use  of  Estimates

     The  consolidated  financial statements include the accounts of the Company
and  its  wholly-owned  subsidiary.  All  significant  intercompany accounts and
transactions  have  been  eliminated  in  consolidation.  The  preparation  of
consolidated  financial  statements  in  conformity  with  accounting principles
generally  accepted  in  the United States requires management to make estimates
and assumptions that affect the amounts reported in the financial statements and
accompanying  notes. Actual results inevitably will differ from those estimates.

Revenue  Recognition

     Revenues  for sales of systems and products are recognized at delivery. For
systems  where services are critical to the functionality of the system, revenue
is  recognized  using  contract  accounting. Systems support fees are recognized
ratably  over  the  period  of  performance.  Professional  services  revenue is
recognized  as these services are provided and is generally billed on a time and
material  basis. Professional services do not involve significant customization,
modification  or  production of the licensed software. Amounts received prior to
the  performance  of  service or completion of a milestone are deferred. Revenue
recognized  for  work  performed  for  which billings have not been presented to
customers  is  recorded  as  unbilled.


                                       25

Cost  of  Operations

     Cost  of  operations consists primarily of personnel costs, costs of media,
production manuals, telephone support, third party equipment, licenses, software
and  other  direct costs related to providing systems, support, and professional
services.

Furniture  and  Equipment

     Furniture  and  equipment are stated at cost. Furniture and equipment under
capital  leases  are  stated  at  the  present  value of minimum lease payments.
Depreciation and amortization are calculated on the straight-line basis over the
estimated  useful lives of the assets ranging from 3 to 7 years. Amortization of
equipment  held under capital leases is provided on the straight-line basis over
the shorter of the estimated useful life of the assets or the life of the lease.

Cash  Equivalents  and  Short-term  Investments

     The  Company  considers  all  highly  liquid  investments  with an original
maturity  of  three  months  or  less to be cash equivalents. As of December 31,
1999,  cash  equivalents  and  short-term  investments consisted of money market
instruments, commercial paper and government agency securities. Cash equivalents
are  carried  at lower of cost or market. In accordance with the requirements of
Statement  of  Financial  Accounting  Standards No. 115, "Accounting for Certain
Investments  in  Debt  and  Equity  Securities,"  the Company has classified its
short-term investments as "available-for-sale". Such investments are recorded at
fair value, with unrealized gains and losses, deemed by the Company as temporary
in nature, reported as a separate component of stockholders' equity. At December
31,  1999  there  were  $27,000 in unrealized losses; at December 31, 1998 there
were  no  unrealized  gains  or  losses.

     Included  in  Cash  and  Cash  Equivalents  at  December  31,  1999,  is
approximately  $123,000,  for a security deposit controlled by the lessor of the
office  building  that  the  Company  currently  occupies.

Software  Capitalization

     The  Company  accounts  for  software  development costs in accordance with
Statement  of Financial Accounting Standards ("SFAS") No. 86 "Accounting for the
Costs  of  Computer  Software  to  be  Sold, Leased, or Otherwise Marketed." The
Company  capitalizes  certain  software  development  costs  subsequent  to  the
establishment  of  technological  feasibility  of  its  products.  Technological
feasibility  is  established  generally  upon completion of a working model of a
product.  Costs incurred prior to technological feasibility are expensed and are
included  as  research  and  development  costs in the accompanying consolidated
financial statements. Amortization of capitalized costs begins when products are
available  for  general  release  to  customers  and  is  computed  on  a
product-by-product  basis  in  the  amount which is the greater of (a) the ratio
that  current  revenues  bear to the total of the current and future anticipated
revenues,  or (b) the straight-line method over the remaining estimated economic
life  of the product, not to exceed five years. Such costs are reflected in Cost
of  Operations  in  the  Company's  consolidated  statement  of  operations.

     The  Company  capitalized approximately $501,000, $556,000, and $308,000 in
software  development  costs  during  1999,  1998  and  1997,  respectively.
Amortization  of  software  development costs approximated $214,000, $51,000 and
$82,000  in 1999, 1998 and 1997, respectively. During the third quarter of 1997,
the  Company  recorded  a  non-recurring  charge totaling approximately $600,000
relating  to  the  write-off of certain capitalized software products related to
discontinued  products.  No  additional  costs  were capitalized during 1997, as
technological  feasibility  had  not  been reached on the Company's new Critical
Care  Series  product.

Income  Taxes

     The Company accounts for income taxes using the asset and liability method.
Under  this  method,  deferred tax assets and liabilities are recognized for the
future  tax  consequences  attributable  to  differences  between  the financial
statement  carrying  amounts  of  existing  assets  and  liabilities  and  their
respective  tax  basis.  Deferred  tax assets and liabilities are measured using
enacted  tax  rates  expected  to  apply to taxable income in the years in which
those  temporary differences are expected to be recovered or settled. The effect
on deferred tax assets and liabilities of a change in tax rates is recognized in
income  in  the  period  that  includes  the  enactment  date.

Current  Vulnerability  Due  to  Certain  Concentrations

     The  Company  currently  depends  on certain suppliers for the provision of
computer hardware to its customers. The Company has not experienced and does not
expect  any  disruption  of  such  services  and  the  Company  believes  that
functionally  equivalent  computer  hardware  is  available  from other sources.

     Financial  instruments  that  potentially  subject  the  Company  to
concentrations  of  credit  risk  consist principally of cash, cash equivalents,
short  term  investments,  and  trade receivables. Concentrations of credit risk
with  respect  to  trade  receivables  result  from the Company's customer base,
comprising  primarily  hospitals  and  other  healthcare  industry  companies.
Management regularly monitors the creditworthiness of its customers and believes
that  it  has  adequately  provided for any exposure to potential credit losses.

Impairment  of  Long-Lived  Assets

     The  Company  complies  with  Statement  of  Financial Accounting Standards
("SFAS")  No.  121  "Accounting  for  the  Impairment  of  Long-Lived Assets and
Long-Lived Assets to be Disposed of." The Company reviews its long-lived assets,
including  intangible  assets  and  property plant and equipment, for impairment
whenever events or changes in circumstances indicate that the carrying amount of
the  assets  may  not  be  fully recoverable. To determine recoverability of its
long-lived  assets,  the  Company evaluates whether future undiscounted net cash
flows  will  be  less  than  the  carrying  amount of the assets and adjusts the
carrying  amount  of  its  assets  to  fair  value.

Reclassification

     Certain  amounts  have been reclassified from prior years to conform to the
current  year  presentation.

(3)  RESTRUCTURING  CHARGE

     During  the  third  quarter  of  1997, the Company recorded a restructuring
charge of $1.6 million related primarily to the Company's decision to revise its
business strategy for the remainder of 1997 and 1998. The Company has decided to
focus on products for high-cost, high-risk patients, APACHE's core strength, and
to  discontinue  or  postpone  the  development  of  certain products (including
certain  cardiovascular  products),  resulting  in  the reduction of the current
workforce.  The  main  components  of  the  charge are as follows: write- off of
capitalized  product  development  costs  related  to  discontinued  products,
write-off  of  intangible assets related to the CardioMac acquisition in January
1997  and termination costs, including severance pay and related benefits. As of
December 31, 1998, substantially all the costs associated with the restructuring
charge  had  been  paid.

Unbilled  accounts represent revenue that has been recognized for work performed
for  which  billings  had not been presented to customers, as such accounts were
not  billable  under contract terms at the balance sheet date. It is anticipated
that substantially all of these accounts will be billed and collected within one
year  of  the  respective  balance  sheet  date.

(7)  INTANGIBLE  ASSETS

     In  December  1996, the Company completed the acquisition of the assets and
certain  liabilities  of  Health  Research  Network ("HRN") for $1.57 million in
cash.  The  acquisition  has  been  accounted  for  using the purchase method of
accounting and resulted in intangible assets totaling $728,000. These assets are

OPERATING  LEASES

     In  November  1999  the  company renewed the lease for their current office
space  for  an  additional  7  years. The previous leased was signed in 1994 and
expired  in November 1999.  The new lease expires in November 2006. Rent expense
is  recorded on a straight-line basis over the term of the lease. The difference
between  rent  payments  and  rent  expense resulted in a deferred rent benefit.

     Total  rent  expense under all operating leases was approximately $452,000,
$474,000  and  $497,000  for  the  years ended December 31, 1999, 1998 and 1997,
respectively.

CAPITAL  LEASES

     In  1997,  the  Company  negotiated  a new capital lease for certain office
equipment.  The  resulting  capital  lease  will  expire  in  2001.

(9)  INCOME  TAXES

     The  Company  had  no provision for income taxes in 1999, 1998 or 1997 as a
result  of  its  net losses for income tax purposes.  The difference between the
tax  provision  and  the amount that would be computed by applying the statutory
federal income tax rate to income before taxes is attributable to the following:

     The  Company has a net operating loss carryforward for income tax reporting
purposes  at  December  31,  1999  of  approximately  $34,500,000, which expires
beginning  in 2003. The Company's ability to use the carryforwards is subject to
limitations  resulting  from  changes  in  ownership, as defined by the Internal
Revenue Code. 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  utilize  the  net  operating  loss  carryforwards.

(10)  STOCKHOLDERS'  EQUITY

Stock  Options

     The Company has an Employee Stock Option Plan (the "Plan") that provides up
to  2,700,000  options  to  be  issued  to employees and Directors (prior to the
adoption  of  the  Non-Employee Director Stock Option Plan in April 1996) of the
Company.  The  Plan  was  amended in March 1999 to increase the number of shares
reserved  for  issuance  under the plan from 2,200,000 to 2,700,000. All options
are  subject  to  forfeiture until vested, and unexercised options expire on the
tenth  anniversary  of  the  year  granted. Vesting periods are from one to five
years.  All  employee stock options issued by the Company have been granted with
exercise  prices  equal  to  or greater than the fair market value of the Common
Stock  on  the  date  of  grant;  accordingly,  the  Company  has  recorded  no
compensation  expense  related  to  such  grants.

     In  June  1996,  the  Company  entered  into  a marketing agreement with an
affiliate of Premier Inc. ("Premier"), which provides buying services to a group
of  approximately  1,800  hospitals.  Pursuant  to  the  agreement,  the Premier
affiliate  has designated the Company as the exclusive supplier to the hospitals
purchasing  through  the  Premier buying group of clinically-based outcomes data
systems  for  high-risk,  high-cost  patients,  including  critical  care,
cardiovascular  care  and  medical-surgical  care patients, through December 31,
1999.  In  return,  the  Company  agreed  to  provide certain discounts to these
hospitals  and,  granted to the Premier affiliate in June 1996, three options to
purchase  up  to  a total of 366,294 shares of Common Stock. Each of the options
have  a  ten-year  term.  One  of  the options vested upon grant and permits the
Premier affiliate to purchase 65,488 shares of Common Stock at an exercise price
of $8.18 per share. The Company valued these options at $369,000, which is being
amortized  over the life of the Premier contract. The other two options  vested,
if  at  all,  based  on  the  volume  of  products  and services sold to Premier
hospitals  and allowed the Premier affiliate to purchase up to 300,806 shares of
Common  Stock  at  an  exercise  price  of $13.00 per share. Performance options
earned through December 31, 1999 totaled 45,695 shares. Valuation of the related
stock  options  was calculated utilizing the Black-Scholes option pricing model.
Expenses  related  to  the performance options are recorded when earned. Expense
for  options  earned  was  $0  in  1999  and  1998  and  $67,000  in  1997.

     In  January 1997, the Company acquired the assets of CardioMac, including a
point-of-care data collection and reporting tool for the cardiac catheterization
laboratory and cardiovascular operating room from Mercy Hospital Medical Center,
Iowa  Health  Centers,  the  Iowa  Heart  Institute and Mark Tannenbaum, MD (its
primary  developer)  for  a  payment  of  $1.35  million  in cash and options to
purchase  up  to  150,000  shares of APACHE Common Stock at an exercise price of
$7.75  per  share.  The options were valued at approximately $224,000 and vested
immediately.

     On  January  2, 1998, the Board of Directors authorized a repricing program
which  allowed active current employees to reprice all their outstanding options
to  purchase  Common  Stock  of  the  Company  for a like number of shares at an
exercise  price  of  $2.00  per share. Options to purchase approximately 480,044
shares  of  Common  Stock were repriced. The vesting schedule is as follows: 20%
would vest immediately for employees with the Company for at least one year; 20%
would  vest on each anniversary over the next five years; and employees with the
Company  less  than one year, options will vest ratably over five years from the
date of grant. The options granted to employees as performance-based options are
excluded  from  this  action.

     On  January 2, 1998, the Board of Directors authorized a repricing of stock
options to a consultant to the Company. Options to purchase approximately 22,029
shares  of  Common  Stock  granted  were cancelled and newly issued at $2.00 per
share  and  vest immediately as of January 2, 1998. Effective November 18, 1998,
the  Board  of  Directors  granted  an  aggregate  of  30,000  options  to three
non-employee  consultants to the Company. The exercise price of these options is
equal  to  the  fair  market value of the Company's Common Stock on November 18,
1998 or $.94. These options have been accounted for in accordance with SFAS 123.

     On November 18, 1998, the Board of Directors authorized a repricing program
which  allowed active current employees to reprice all their outstanding options
to  purchase  Common  Stock  of  the  Company  for a like number of shares at an
exercise  price  of  $.94  per  share. Options to purchase approximately 845,566
shares  of  Common  Stock were repriced. The vesting schedule remained the same.

     The  following  is  a  summary of the Company's option transactions for the
years  ending  December  31,  1997,  1998  and  1999:

</TABLE>

     Options outstanding at December 31, 1999 have exercise prices between $0.59
and  $13.00,  with  a  weighted  average  exercise price of $2.62 and a weighted
average remaining contractual life of 7.0 years. At December 31, 1999, 1,435,141
options  were  exercisable  with  a  weighted  average  exercise price of $4.04.

     At  December  31, 1999, options for 347,215 shares were available for grant
under  the  Plan.

NON-EMPLOYEE  DIRECTOR  STOCK  OPTION  PLAN

     In  April  1996,  the Company adopted its Non-Employee Director Option Plan
(the  "Director  Option  Plan"), pursuant to which non-employee directors of the
Company  will  be  granted an option to purchase 2,500 shares of Common Stock on
January 1, of each calendar year for each year of service. The exercise price of
such  options shall be at the fair market value of the Company's Common Stock on
the  date of grant. Stock options granted under the Director Option Plan may not
be  transferred  other  than by will or by the laws of descent and distribution.
The  Company  has  reserved 70,000 shares of Common Stock for issuance under the
Director Option Plan. The Director Option Plan may be terminated by the Board of
Directors at any time. Upon the occurrence of a Change of Control, as defined in
the  Director  Option  Plan, all outstanding unvested options under the Director
Option  Plan  immediately  vest.  As  of  December  31, 1999, 42,500 shares were
granted  under  the  Director  Option  Plan.

     At  December  31,  1999  options for 27,500 shares were available for grant
under  the  Director  Option  Plan.

NON-EMPLOYEE  DIRECTOR  SUPPLEMENTAL  STOCK  OPTION  PLAN

      In  May  1999,  the Company adopted its Non-Employee Director Supplemental
Stock Option Plan (the "Director Supplemental Option Plan"), that provides up to
120,000  options  to  be  issued  to the Directors of the Company.  The exercise
price  of  such  options  shall  not  be  less than the fair market value of the
Company's  Common  Stock on the date of grant.  The Director Supplemental Option
Plan  may  be terminated by the Board of Directors at any time.  Upon occurrence
of  a Change in Control as defined in the Director Supplemental Option Plan, all
outstanding  unvested  options  under the Director Supplemental Option Plan vest
immediately.  As  of  December  31, 1999, options for 115,200 were granted under
the  Director  Supplemental  Option  Plan.


                                       31
<PAGE>
     At  December  31,  1999,  options for 4,800 shares were available for grant
under  the  Director  Supplemental  Option  Plan.


EMPLOYEE  STOCK  PURCHASE  PLAN

     Effective  May 1, 1996, the Company adopted an Employee Stock Purchase Plan
(the  "Purchase  Plan"). A total of 210,000 shares of Common Stock are available
for  purchase  under  the  Purchase  Plan.  The  Purchase  Plan permits eligible
employees  to  purchase  Common  Stock through payroll deductions, which may not
exceed 8% of an employee's base compensation, including commissions, bonuses and
overtime,  at  a price equal to 85% of the fair market value of the Common Stock
at  the  beginning  of each offering period or the end of a three month purchase
period, whichever is lower. The Board of Directors has the authority to amend or
terminate  the  Purchase  Plan  provided no such action may adversely affect the
rights  of  any  participant.

     At  December  31, 1999, 90,027 shares were available for purchase under the
Employee  Stock  Purchase  Plan.

STOCK  OPTION  PLANS

     The  Company  applies  APB Opinion No. 25 in accounting for its Stock based
compensation  plans  and,  accordingly, no compensation cost has been recognized
for  its  stock  option  plans and employee stock purchase plan in the financial
statements. Had the Company determined compensation cost based on the fair value
at the grant date for these plans under SFAS No. 123 "Accounting for Stock Based
Compensation," the Company's net income would have been reduced to the pro forma
amounts  indicated  below  (in  thousands):

     The fair value of each option grant is estimated on the date of grant using
the  Black-Scholes  option  pricing  model  with  the following weighted-average
assumptions: January 1, 1999 through December 31, 1999 - expected dividend yield
of  0%, risk-free interest rate of 5.86%, expected volatility factor of 202.34%,
and  an  expected  life  of 6 years; January 1, 1998 through December 31, 1998 -
expected  dividend  yield  of  0%,  risk-free  interest  rate  of 4.5%, expected
volatility  factor  of 228.70%, and an expected life of 6 years; January 1, 1997
through  December  31,  1997 - expected dividend yield of 0%, risk-free interest
rate  of 5.71%, expected volatility factor of 105.35%, and an expected life of 6
years.

     Pro  forma  net  loss  reflects  only options granted in 1996 through 1999.
Therefore,  the  full  impact of calculating compensation cost for stock options
under  SFAS No. 123 is not reflected in the pro forma net loss amounts presented
above because compensation cost is reflected over the options' vesting period of
5  years  and  compensation cost for options granted prior to January 1, 1995 is
not  considered.

STOCK  WARRANTS

     The Company has 17,483 outstanding warrants issued to a stockholder in 1991
with  an  exercise  price  of  $2.86  per  share  that  expire  in 2001; 349,653
outstanding  warrants  issued  to stockholders in 1995 with an exercise price of
$1.43  per share that expire in 2000; and 110,069 outstanding warrants issued to
stockholders  in  1995  with an exercise price of $8.18 per share that expire in
2000.

</TABLE>

     Options  to  purchase  2,405,041 shares of common stock were outstanding at
December  31,  1999  but  were  not  included  in the computation of diluted EPS
because  the  options'  weighted  average  exercise  price  was greater than the
average  market  price  of  the  common  shares and the affect of including such
shares  would  be  anti-dilutive  to  the  per  share  amount.

     The Company has 477,205 warrants outstanding at December 31, 1999 that were
not  included  in  the computation of diluted EPS because the warrants' weighted
average  exercise  price was greater than the average market price of the common
shares and the affect of including such shares would be anti-dilutive to the per
share  amount.


(12)  WRITE-OFF  OF  PRODUCT  DEVELOPMENT  AND  RELATED  COSTS

     During  the  fourth  quarter  of 1996, the Company recorded a non-recurring
charge  totaling  $1.1  million relating to the write-off of capitalized product
development  costs  totaling $375,000 and fees totaling $725,000 arising from an
earlier  agreement  with  QIMC,  a  healthcare  focused,  business-led coalition
located in Cleveland. During 1994, the Company entered into an exclusive 10-year
licensing agreement with QIMC for its database and methodologies. As of December
31,  1997,  the  Company  was  committed to pay an aggregate of $406,000 through
March  1999 for the license and marketing services fees associated with the sale
of  the  Company's  product related to these methodologies. The Company recorded
this  charge  because  the  joint marketing arrangement has not met management's
expectations,  resulting  in  limited  sales of the related product during 1996.
This  trend was  expected to continue through 1999 and, therefore, the projected
sales  for  the related product and support revenue earned from existing clients
are  not considered adequate to support the related expenses associated with the
QIMC  agreement  and  the  capitalized  product development costs. The remaining
commitment  totaling  $87,500  was included in other accruals as of December 31,
1998.  At  December  31,  1999  that  commitment  had  been satisfied.


(13)  COST  OF  OPERATIONS  AND  GROSS  MARGIN  BY  PRIMARY  REVENUE  SOURCES

(14)  RELATED  PARTY  TRANSACTION

     The Company entered into a license agreement with a stockholder in February
1995.  The  agreement was amended in December 1996. Under the amended agreement,
the  stockholder  is  licensed  to  sell  a product of the Company for which the
stockholder  will  pay  a  royalty  after a set number of sales. No sales of the
product have been made since 1995. The Company entered into a reseller agreement
with  this  stockholder  in March 1998. Under the agreement, the stockholder may
resell  certain  products  of  the  Company  to  a  named  hospital  system.

(15)  EMPLOYEE  BENEFIT  PLANS

     The Company sponsors a profit sharing plan (the "Plan") intended to qualify
under Section 401(k) of the Internal Revenue Code. All employees are eligible to
participate  in the Plan after three months of service. Employees may contribute
a  portion of their salary to the Plan, subject to annual limitations imposed by
the  Internal  Revenue  Code.  The  Company  may  make matching or discretionary
contributions  to  the Plan at the discretion of the Board of Directors, but has
made  no  such  contribution to date. Employer contributions generally vest over
seven  years.

     The  Company  sponsors  a defined benefit pension plan (the "pension plan")
covering  all former employees of National Health Advisors. The pension plan was
amended  to  freeze benefit accruals and the entry of new participants effective
October  31, 1997. Because the expected future service of participants under the
pension  plan  was  eliminated during 1997, this constitutes a curtailment under
the  provisions  of  SFAS  No.  88,  "Employers  Accounting  for Settlements and
Curtailments  of  Defined  Benefit  Pension Plans and for Termination Benefits".

     The benefits are based on final average compensation and are offset by each
employee's  interest in the Company's profit sharing plan. The Company's funding
policy  is  to  contribute  annually  an amount that can be deducted for federal
income tax purposes and meets minimum funding standards, using an actuarial cost
method  and  assumptions  which  are  different  from  those  used for financial
reporting.

over  the  useful life of the improvement or equipment, as reasonably determined
by  Landlord,  together  with an interest factor on the unamortized cost of such
item  equal  to  the  lesser  of (i) twelve percent (12%) per annum, or (ii) the
maximum  rate  of  interest  permitted  by  applicable  law.

          In addition, notwithstanding anything to the contrary contained in the
definition of Operating  Expenses set forth in this Section  1(b)(8),  Operating
Expenses shall not include the following:

               (iii)Costs and  expenses  which  would  otherwise  be included in
                    Operating   Expenses   but   which  are  in  excess  of  the
                    competitive   rates  for  similar   services  of  comparable
                    quality,  rendered by persons or entities of similar  skill,
                    competence   and   experience,   provided   however  that  a
                    management  fee of four percent (4%) of gross revenues shall
                    be deemed  not to exceed the  competitive  rate and shall be
                    included  in the  Base  Year  Operating  Expenses  and  each
                    comparative year. Management fees for the Base Year and each
                    comparative year shall be computed as if the vacant areas of
                    the Building were fully rented at ninety-five  percent (95%)
                    of the average  rents being  charged in the Building  during
                    the applicable Lease Year.

               (iv) To the extent that employees are not employed exclusively at
                    the  Building,  the costs and expenses  with respect to such

                    Building.

               (vi) Any expense for which Landlord is reimbursed from any tenant
                    or other third  party,  or under the terms of any  insurance

                    business  of the entity  which  constitutes  Landlord as the

               (xvii) Rent for space which is not  actually  used by Landlord in

request,  complete  and  execute  the  letter  attached  hereto as Exhibit C and

     3.   Rent  and  Additional   Charges;   Computation  of  Operating  Expense
          ----------------------------------------------------------------------
          Increases.
          ---------

          (a) Payment of Basic Rent and Additional Charges. Tenant shall pay the
              --------------------------------------------
Basic Rent and  Parking  Rent in equal  monthly  installments  in advance on the
first day of each month  during the Term  commencing  on the Lease  Commencement
Date; provided,  however, if the Lease Commencement Date is not the first day of
a month,  Basic Rent and  Parking  Rent for the period  commencing  on the Lease
Commencement  Date and  ending  on the last day of the  month in which the Lease
Commencement  Date  occurs  shall  be  pro-rated  for  each  day at the  rate of
one-thirtieth (1/30) or one-thirty-first  (1/31) of the full monthly installment
of Basic Rent and Parking Rent and paid on the Lease  Commencement  Date. If any
due and owing Basic Rent or Parking  Rent is underpaid as a result of failure to
make any  required  adjustment  thereto  or other  cause,  after  such  required
adjustment  thereto or other  cause,  Tenant  shall pay such  deficiency  in its
entirety  along with the next  monthly  payment  of Basic Rent or Parking  Rent.
Tenant shall also pay the Proportionate  Share of Operating Expense Increases as
provided in Sections 1(a)(7) and 3(b) hereof.  The Basic Rent and all Additional
Charges shall be paid  promptly when due, in lawful money of the United  States,
without  notice  or  demand  and  without  deduction,   diminution,   abatement,
counterclaim  or set-off of any amount or for any reason  whatsoever,  EXCEPT AS
OTHERWISE  PROVIDED HEREIN,  to Landlord at Landlord's Notice Address or at such
other  address  or to such  other  person  as  Landlord  may  from  time to time
designate.  If Tenant makes any payment to Landlord by check,  the same shall be
by check of Tenant or an affiliated  entity of Tenant only,  and Landlord  shall
not be required to accept the check of any other person,  and any check received
by Landlord  shall be deemed  received  subject to  collection.  If any check is
mailed by Tenant, it should mailed to Landlord's Notice Address and Tenant shall
post such check in sufficient time prior to the date when payment is due so that
such check will be received  by  Landlord on or before the date when  payment is
due.  Tenant  shall  assume the risk of  lateness  or failure of delivery of the
mails.  If,  during the Term,  Landlord  receives two or more checks from Tenant
which are  returned by Tenant's  bank for  insufficient  funds or are  otherwise
returned unpaid,  Tenant agrees that all checks  thereafter shall be either bank
certified or bank cashier's checks.  All bank service charges resulting from any
bad checks shall be borne by Tenant.  Notwithstanding  the  foregoing,  UPON ONE
HUNDRED EIGHTY (180) DAYS PRIOR WRITTEN NOTICE TO TENANT,  AND TO THE EXTENT THE
USE OF AN ACH, AS HEREINAFTER  DEFINED,  IS FEASIBLE FOR TENANT,  Landlord shall
have the option of requiring Tenant to make all payments of Basic Rent by use of
an  Automated  Clearing  House  ("ACH")  debit or  credit,  at the option of the
Tenant.  The Rent reserved under this Lease shall be the total of all Basic Rent
and Additional  Charges,  increased and adjusted as elsewhere  herein  provided,
payable during the entire Term and, accordingly, the methods of payment provided
for herein, namely, annual and monthly rental payments, are for convenience only
and are made on account of the total Rent reserved hereunder, provided, however,
that unless this Lease has been  terminated  as a result of an Event of Default,
Landlord cannot demand payment of the Total Rent reserved  hereunder in anything
but monthly rental payments.

          (b) Computation of Operating Expenses.
              ---------------------------------

               (1) Following the  expiration of each Lease Year,  Landlord shall
submit to Tenant a statement  setting forth in  reasonable  detail the Operating
Expenses for the  preceding  Lease Year and the amount,  if any, due to Landlord
from Tenant  pursuant to Section  1(a)(7) for such Lease Year on account of such
Operating Expenses (the "Statement").  In addition,  following the expiration of
the Base Year,  Landlord  shall  submit to Tenant a Statement  setting  forth in
reasonable detail the Operating Expenses for the Base Year. Such Statement shall
constitute a final determination  between the parties for the period represented
thereby,  subject only to proper  adjustments  subsequently made by Landlord and
Tenant's right to dispute such  determination and any such adjustment.  Prior to
the rendition of any such  Statement,  Tenant shall continue to pay to Landlord,
on the first day of each month, the  installments of the Operating  Expenses due
from Tenant during the preceding Lease Year. If any such Statement shows any


                                        8
<PAGE>
Operating  Expenses  due  from Tenant with respect to such preceding Lease Year,
then  Tenant shall make payment of any unpaid portion thereof within THIRTY (30)
days  after  receipt  of  such  Statement.  Tenant shall also pay to Landlord as
Additional  Charges,  commencing  as  of  the first day of the month immediately
following  the  rendition  of  such Statement and on the first day of each month
thereafter  until  a new statement is rendered, 1/12th of the Operating Expenses
reasonably  estimated  by  Landlord  to be due from Tenant for the current Lease
Year  (WHICH  ESTIMATE  SHALL  NOT  EXCEED FIVE PERCENT (5%) MORE THAN THE PRIOR
LEASE  YEAR'S  OPERATING  EXPENSES);  and, Tenant shall also pay to Landlord, as
Additional Charges, within THIRTY (30)  days after receipt of such Statement, an
amount  equal  to the difference between (a) the product obtained by multiplying
the  estimated  Operating Expenses for the current Lease Year by a fraction, the
denominator  of  which  shall be twelve (12) and the numerator of which shall be
the number of months of the current Lease Year which shall have elapsed prior to
the  first  day  of  the  month  immediately  following  the  rendition  of such
Statement,  and  (b) the sum of all previous Operating Expense payments (if any)
made  by  Tenant  with  respect  to such prior months in the current Lease Year.
Payments  based  on  the estimated Operating Expenses for the current Lease Year
shall  be  credited toward the actual Operating Expenses due from Tenant for the
current  Lease  Year,  subject  to adjustment as and when the Statement for such
current  Lease  Year  is  rendered  by  Landlord.

               (2) Operating  Expenses are included in the Basic Rent payable by
Tenant  during the first  twelve (12) months of the Initial  Term.  Tenant shall
commence paying the  Proportionate  Share of Operating  Expense Increases on the
first anniversary of the Lease Commencement Date. Upon the date of expiration or
termination of this Lease,  whether the same be the date  hereinabove  set forth
for the  expiration  of the Term,  or any prior or  subsequent  date, a prorated
share of said Operating Expenses for the Lease Year during which such expiration
or termination  occurs shall become due and payable by Tenant to Landlord WITHIN
TEN (10) DAYS OF LANDLORD'S  NOTICE THEREOF TO TENANT, if it was not theretofore
already  billed and paid. The said prorated share shall be based upon the length
of time that the Term  shall have been in  existence  during  such  Lease  Year.
Landlord  shall,  as soon as  reasonably  practicable,  cause  statements of the
Operating  Expenses for that Lease Year to be prepared and  furnished to Tenant.
Landlord and Tenant shall thereupon make appropriate adjustments of amounts then
owing. Landlord's and Tenant's obligation to make the adjustments referred to in
subparagraphs  (1) and (2) of this Section 3(b) shall survive any  expiration or
termination  of this Lease AND ANY  OVERPAYMENT  OR  UNDERPAYMENT  OF  OPERATING
EXPENSES SHALL BE PROMPTLY REMITTED. Any delay or failure of Landlord in billing
any Operating Expenses  hereinabove provided shall not constitute a waiver of or
in any way  impair the  continuing  obligation  of Tenant to pay such  Operating
Expenses.

                    (i) The  Operating  Expenses  for the  Base  Year  shall  be
adjusted,  if  necessary,  to a  level  of  that  of a 95%  occupied  and  fully
operational  office building at cost levels  prevailing in the geographic market
in which the  Building is located for an entire Lease Year.  This  APPROPRIATELY
DOCUMENTED adjustment shall include (a) when Building systems are under warranty
during the Base Year, an adjustment for the cost of service  contracts and other
expenses that would have been incurred in the absence of such warranties; (b) an
adjustment  for all other  expenses that are not incurred if the Building is new
and  start-up  discounts  or  similar  savings  have  been  achieved;   and  (c)
adjustments  for all other  atypical costs that occur or do not occur during the
Base Year other  than  those  costs  which  would  occur in the Base Year in the
ordinary course of business.  The purpose of these  adjustments is to include in
the Building Operating Expenses for the Base Year all reasonable cost components
that occur or are likely to occur in later  years and would be  reasonable  cost
components in the Base Year but for the fact that it is the Base Year.

                    (ii) 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 Building
Operating  Expenses 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. The expense incurred for such item during
the first year shall be subject to the adjustments  described in the immediately
preceding paragraph.


                                        9
<PAGE>
          (c)  Interest.  If Tenant  fails to pay any Basic  Rent or  Additional
               --------
Charges  within five (5) days after the same becomes due and  payable,  interest
shall,  at  Landlord's  option,  accrue from the date due on the unpaid  portion
thereof at the rate of one percent (1%) per month or five (5) percentage  points
above the Prime Rate in effect on such due date,  whichever is higher, but in no
event at a rate higher than the maximum rate allowed by law. Such interest shall
be  deemed   additional  rent  hereunder  and  shall  be  collectible  as  such.
NOTWITHSTANDING  THE FOREGOING,  LANDLORD AGREES TO WAIVE THE IMPOSITION OF SUCH
INTEREST  ON THE  FIRST TWO (2)  OCCASIONS  IN ANY  TWELVE  (12)  MONTH  PERIOD,
PROVIDED THE OVERDUE  PAYMENT IS MADE WITHIN FIVE (5) DAYS AFTER  LANDLORD GIVES
TENANT WRITTEN NOTICE THAT PAYMENT WAS NOT MADE WHEN DUE.

          (d)  Accord  and  Satisfaction.  No  payment  by Tenant or  receipt by
               -------------------------
Landlord of any lesser amount than the amount  stipulated  to be paid  hereunder
shall be deemed other than on account of the earliest  stipulated  Basic Rent or
Additional  Charges;  nor shall any  endorsement  or  statement  on any check or
letter be deemed an accord and  satisfaction,  and Landlord may accept any check
or payment without  prejudice to Landlord's  right to recover the balance due or
to pursue any other remedy available to Landlord.

          (e) Late  Payment  Charge.  If Tenant  fails to pay any Basic  Rent or
              ---------------------
Additional  Charges  within ten (10) days after the same become due and payable,
Tenant  shall  also pay to  Landlord  a late  payment  service  charge (to cover
Landlord's  administrative  and overhead  expenses of processing  late payments)
equal to the greater of Five  Hundred  ($500.00)  or Five  Percent  (5%) of such
unpaid sum. Such payment shall be deemed  liquidated  damages and not a penalty,
but shall not excuse the timely payment of Rent.  Acceptance of such late charge
by  Landlord  shall in no event  constitute  a waiver of Tenant's  default  with
respect to such overdue amount,  nor prevent Landlord from exercising any of the
other rights and remedies granted hereunder including the assessment of interest
under Section 3(c). NOTWITHSTANDING THE FOREGOING,  LANDLORD AGREES TO WAIVE THE
IMPOSITION  OF SUCH LATE  CHARGES ON THE FIRST TWO (2)  OCCASIONS  IN ANY TWELVE
(12) MONTH  PERIOD,  PROVIDED  THE OVERDUE  PAYMENT IS MADE WITHIN FIVE (5) DAYS
AFTER LANDLORD GIVES TENANT WRITTEN NOTICE THAT PAYMENT WAS NOT MADE WHEN DUE.

          (f) Right to Audit.  Within  ninety  (90) days  after  receipt  of the
              --------------
Operating Expenses  Statement,  Tenant shall have the right, at its expense,  to
inspect Landlord's Operating Expenses records relating to the Lease Year covered
by the Statement,  including the Statement  covering the Base Year,  except that
any inspection  that discloses  that Tenant's  Proportionate  Share of Operating
Expenses  has been  overstated  by more  than  seven  percent  (7%)  shall be at
Landlord's expense.  The inspection must be completed within thirty (30) days of
commencement.  Before conducting any inspection, Tenant must pay the full amount
of  Operating  Expenses  billed and there must not be an Event of Default of any
other Lease  provisions.  Tenant may review only those  records of Landlord that
are specifically related to Operating Expenses.  The audit shall be conducted in
a location IN THE NORTHERN VIRGINIA, WASHINGTON, D.C. METROPOLITAN AREA and at a
time  reasonably  determined  by Landlord.  If Landlord  unreasonably  delays in
allowing Tenant access to its records, the time periods provided herein shall be
extended to account for such unreasonable  delay.  Upon receipt thereof,  Tenant
will  deliver  to  Landlord  a copy of any  report  procured  as a result of the
inspection and all accompanying data. Tenant's  Proportionate Share of Operating
Expense Increases shall be appropriately adjusted based upon the results of such
audit.  Tenant will keep  confidential  any  information  gained through and the
result of any  inspection.  Tenant may not conduct an inspection more often than
once each Lease Year.  Tenant may audit  records  only with respect to the Lease
Year in question;  PROVIDED, HOWEVER, THAT TENANT SHALL HAVE A ONE (1) TIME ONLY
RIGHT TO AUDIT THE BASE YEAR..

location and materials of such signage shall be in  accordance  with  Landlord's
standard Building signage package.

          (b) Access. Landlord shall have reasonable access UPON TWENTY-FOUR
              ------
(24)  HOURS  PRIOR  NOTICE TO TENANT (EXCEPT IN EMERGENCIES) to and reserves the
right  to  inspect,  erect,  use,  connect to, maintain and repair pipes, ducts,
conduits,  cables,  plumbing,  vents  and wires, and other facilities in, to and
through  the  Leased  Premises  as  and  to  the extent that Landlord may now or
hereafter  deem  to  be  necessary  or  appropriate for the proper operation and


                                       11
<PAGE>
maintenance  of  the Building (including the servicing of other occupants of the
Building)  and  the right at all times to transmit water, heat, air conditioning
and  electric  current through such pipes, conduits, cables, plumbing, vents and
wires  and  the  right  to  interrupt  the same in suspected emergencies without
eviction  of  Tenant or abatement of Rent.  All repairs and maintenance required
by  Landlord  pursuant  to  this  Section  4(b) shall be performed in a good and
workmanlike  manner  and  with  due  diligence  to  minimize  any  unreasonable
disruption  to  Tenant's  business.  NO WORK PERFORMED BY LANDLORD IN ACCORDANCE
WITH THIS SECTION SHALL RESULT IN A PERMANENT REDUCTION OF TENANT'S USABLE AREA.

          (c) Interruption in Services. Tenant agrees that Landlord shall not be
              ------------------------
liable to Tenant for its failure to furnish gas, electricity, telephone service,
water, HVAC or any other utility services or building services when such failure
is occasioned, in whole or in part, by repairs,  replacements,  or improvements,
by  any  strike,  lockout  or  other  labor  trouble,  by  inability  to  secure
electricity,  gas, water, telephone service or other utility at the Building, by
any accident, casualty or event arising from any cause whatsoever, including the
negligence  of  Landlord,  its  employees,   agents  and  contractors,  by  act,
negligence  or default of Tenant or any other person or entity,  or by any other
cause  including  bomb  scares,  and such  failures  shall  never be  deemed  to
constitute  an eviction or  disturbance  of Tenant's use and  possession  of the
Leased  Premises  or  relieve  Tenant  from the  obligation  of  paying  rent or
performing any of its obligations under this Lease. Furthermore,  subject to the
provisions  contained in the last sentence of this Section 4(c)  Landlord  shall
not be liable under any  circumstances for loss of property or for injury to, or
interference with, Tenant's business,  including,  without  limitation,  loss of
profits,  however  occurring,  through or in connection  with or incidental to a
failure to furnish any such  services  or  utilities.  Landlord  may comply with
voluntary controls or guidelines promulgated by any governmental entity relating
to the use or  conservation of energy,  water,  gas, light or electricity or the
reduction of automobile  or other  emissions  without  creating any liability of
Landlord  to Tenant  under this Lease.  Notwithstanding  the  foregoing,  if any
interruption  of  service  shall  continue  for more than  five (5)  consecutive
business  days and  shall  render  all or any  portion  of the  Leased  Premises
unusable or  inaccessible  for the normal conduct of Tenant's  business,  and if
Tenant does not in fact use or occupy such portion of the Leased Premises,  then
all Basic Rent and  Additional  Charges  payable  hereunder with respect to such
portion of the Leased Premises which Tenant does not occupy shall be abated from
the date of such  interruption  until  full use of such  portion  of the  Leased
Premises is restored to Tenant.  Nothing in the Lease shall be deemed to release
Landlord from liability for damages arising from the gross negligence or willful
misconduct of Landlord, or its employees, agents and contractors.

     5.   Maintenance and Repairs.
          -----------------------

          Subject  to  the   provisions  of  Section  8  below  and  subject  to
reimbursement by Tenant, where applicable,  in accordance with the provisions of
Sections  1(b)(8)  and 3 herein,  Landlord  agrees to  maintain  the  structural
portions  of the  Building  and  central  Building  mechanical,  electrical  and
plumbing systems, FIRE AND LIFE SAFETY SYSTEMS IN THE COMMON AREAS, RESTROOMS IN
THE COMMON AREAS,  the Common Areas,  and Building  standard items in the Leased
Premises but only those behind walls or at or above finished  ceilings,  in good
order and repair throughout the Term AND LANDLORD SHALL OTHERWISE MANAGE,  LEASE
AND OPERATE THE BUILDING IN A "FIRST-CLASS"  MANNER THROUGHOUT THE TERM. Tenant,
and  not  Landlord,   shall  be  responsible   for  (i)  maintaining  all  other
improvements to the Leased Premises  including Building standard items which are
not behind walls or at or above  finished  ceilings and any Special Items in the
Leased Premises, and (ii) SUBJECT TO SECTION 7(C) AND TO THE EXTENT SUCH REPAIRS
ARE NOT COVERED BY INSURANCE REQUIRED UNDER THIS LEASE, reimbursing Landlord for
the  full  cost of any  repairs  to the  Leased  Premises  or to any part of the
Building caused by the unreasonable  wear and tear by or negligence of Tenant or
its agent or  employees,  such  reimbursement  to be  collectible  as Additional
Charges  hereunder  WITHIN  THIRTY (30) DAYS AFTER DEMAND FROM  LANDLORD,  WHICH
DEMAND SHALL BE APPROPRIATELY  DOCUMENTED . Any contractors  performing  repairs
which are the  responsibility of Tenant hereunder must receive the prior written
approval  of  Landlord,  which  approval  shall  not be  unreasonably  withheld,
conditioned or delayed.

REFRIGERATORS,  television  sets,  video and telephone  conferencing  equipment,
computers and peripheral equipment,  telecopiers,  photocopiers,  radios, clocks
and lamps),  without first  obtaining the written  consent of Landlord,  who may
condition  such consent upon  Tenant's  agreement to make direct  payment to the
local  utility  company  or the  payment  by Tenant of an  Additional  Charge to
Landlord,  for Tenant's excessive consumption of electricity and for the cost of
additional  wiring or metering  which may be required for the  operation of such
equipment and machinery;  (ix) not to install any other equipment of any kind or

any repairs, changes,  replacements or additions to, or in the use of, the water
system,  heating system,  plumbing system, air conditioning system or electrical
system of the Leased  Premises or the  Building,  without  first  obtaining  the
written  consent of Landlord  (provided  that Tenant,  at Tenant's sole cost and
expense,  may install such supplemental heating and cooling and other systems as
may be required to correct or avoid such  problems.  Any work  described  herein
shall be done in accordance with the provisions of Section 22 of the Lease;  and
(x) at all times to comply with the Requirements.  Throughout the Term, Landlord

outlets which such five (5) watts  connected load shall be exclusive of lighting
and Landlord's Building heating/air conditioning and ventilation services.

          (c)  Compliance.  Tenant will not use or occupy the Leased Premises in
               ----------
violation  of  any  Requirement.   If  any  governmental  authority,  after  the
commencement of the Term,  shall contend or declare that the Leased Premises are
being used for a purpose which is in violation of any  Requirement,  then Tenant
shall, immediately upon demand from Landlord, discontinue such use of the Leased
Premises.  If thereafter  the  governmental  authority  asserting such violation
threatens, commences or continues criminal or civil proceedings against Landlord
for Tenant's failure to discontinue such use, in addition to any and all rights,
privileges and remedies given to Landlord under this Lease for default  therein,
Landlord  shall have the right to terminate this Lease  forthwith.  Tenant shall
indemnify and hold  Landlord  harmless of and from any and all liability for any
such violation or violations.

<PAGE>
          (d) Rules and  Regulations.  Tenant and its agents and employees shall
              ---------------------
comply  with  and  observe  all  rules  and  regulations   concerning  the  use,
management,  operation,  safety and good order of the  Leased  Premises  and the
Building  which may from time to time  hereafter  be  promulgated  by  Landlord.
Initial  rules and  regulations,  which  shall be  effective  until  amended  by
Landlord,  are  attached  hereto as  Exhibit E.  Tenant  shall be deemed to have
                                     ---------
received  notice of any  amendment to the rules and  regulations  when a copy of
such amendment has been  delivered to Tenant at the Leased  Premises or has been
mailed to Tenant in the  manner  prescribed  for the giving of  notices.  Tenant
shall comply with all fire protective  rules and regulations  promulgated by the
Landlord  for the safety of the  Building  and its  occupants,  including  rules
prescribing  certain types of materials and prohibiting other types of materials
in the Building.  Landlord  shall not be responsible to Tenant for any violation
of the rules and  regulations,  or the covenants or agreements  contained in any
other lease,  by any other tenant of the  Building,  or its agents or employees,
and Landlord may waive any or all of the rules or  regulations in respect of any
one or more  tenants  for good cause so long as such rules and  regulations  are
otherwise  non-discriminatorily  enforced,  and  such  waiver  does  not  change
Tenant's   obligations  or  rights  under  this  Lease.  IN  THE  EVENT  OF  ANY
INCONSISTENCY BETWEEN ANY PROVISION OF THIS LEASE AND THE RULES AND REGULATIONS,
THE APPLICABLE LEASE PROVISION SHALL CONTROL.

     7.   Insurance.
          ---------

          (a) Tenant

               (1) Types;  Limits.  Tenant,  at Tenant's  sole cost and expense,
                   --------------
shall  obtain and  maintain in effect at all times  during the Term, a policy of
commercial   general  liability   insurance  with  broad  form  property  damage
endorsement, naming Landlord, Tysons II Land Company, L.L.C., Lerner Enterprises
Limited  Partnership,  Lerner  Corporation,  and  (at  Landlord's  request)  any
mortgagee of the Building, any ground landlord and any other agent as additional
named  insured(s),  protecting  such parties  against any  liability  for bodily
injury,  death or  property  damage  caused  by  Tenant  or  Tenant's  agents or
employees  occurring  upon,  in or about any part of the  Building,  the  Leased
Premises or any Common Areas thereto, with such policies to afford protection to
the limit of not less than Two  Million  Dollars  ($2,000,000)  with  respect to
bodily  injury  or death to any one  person,  to the  limit of not less than Two
Million  Dollars  ($2,000,000)  with  respect  to bodily  injury or death to any
number or  persons  in any one  accident,  and to the limit of not less than Two
Million Dollars  ($2,000,000)  with respect to damage to the property of any one
owner,  and with a deductible no greater than One Thousand  Dollars  ($1,000.00)
for any single occurrence.

               (2)  Policies.  The insurance  policy  required to be obtained by
                    --------
Tenant  under  this  Lease  (i)  shall be  issued  by an  insurance  company  of
recognized  responsibility  licensed to do business in the jurisdiction in which
the Building is located,  and (ii) shall be written as primary  policy  coverage
and not contributing with or in excess of any coverage which Landlord may carry.
Neither the issuance of any insurance  policy required under this Lease, nor the
minimum limits  specified  herein with respect to Tenant's  insurance  coverage,
shall be deemed to limit or restrict in any way Tenant's liability arising under
or out of this  Lease.  With  respect to each  insurance  policy  required to be
obtained by Tenant under this Section, on or before the Lease Commencement Date,
and at least thirty (30) days before the  expiration  of any expiring  policy or
certificate previously furnished, Tenant shall deliver to Landlord a certificate
of  insurance  therefor,  together  with  evidence of payment of all  applicable
premiums. Each insurance policy required to be carried hereunder by or on behalf
of Tenant shall provide (and any  certificate  evidencing  the existence of each
such insurance  policy shall  certify) that such  insurance  policy shall not be
canceled  unless  Landlord  shall have received  thirty (30) days' prior written
notice of such cancellation.


                                       14
<PAGE>
               (3)  Prohibitions.  Tenant  shall not do,  permit or suffer to be
                    ------------
done any act, matter,  thing or failure to act in respect of the Leased Premises
and/or the  Building  that will  invalidate  or be in  conflict  with  insurance
policies covering the Building or any part thereof,  and shall not do, or permit
anything to be done,  in or upon the Leased  Premises  and/or the  Building,  or
bring or keep anything therein, which shall increase the rate of insurance on or
related to the Building or on any property located therein. If, by reason of the
failure  of  Tenant  to  comply  with the  provisions  of this  subsection,  the
insurance  rate shall at any time be higher  than it  otherwise  would be,  then
Tenant shall reimburse Landlord on demand, for that part of all premiums for any
insurance  coverage  that shall have been charged  because of such  violation by
Tenant and which  Landlord shall have paid on account of an increase in the rate
or rates in its own policies of insurance.

               (4) Hold Harmless; Indemnification; Waiver of Subrogation. Tenant
                   -----------------------------------------------------
hereby agrees to indemnify and hold harmless  Landlord,  Tysons II Land Company,
L.L.C., Lerner Enterprises Limited Partnership,  Lerner Corporation,  Landlord's
employees,  agents,  mortgagees  and ground lessors  (collectively,  "Landlord's
Indemnities")  from and against any and all claims,  losses,  actions,  damages,
liabilities and expenses (including  attorneys' fees)  (collectively,  "Claims")
that  (i)  arise  from  or are in  connection  with  Tenant's  possession,  use,
occupation, management, repair, maintenance or control of the Leased Premises or
the Building,  or any portion  thereof,  or (ii) arise from or are in connection
with any act or omission of Tenant or Tenant's  agents,  or employees,  or (iii)
result from any default,  breach,  violation or non-performance of this Lease or
any provision  herein by Tenant,  or (iv) result from injury or death to persons
or damage to  property  sustained  in or about the  Leased  Premises;  provided,
however, Tenant shall not be required to indemnify any of Landlord's Indemnities
from any Claims arising from the gross  negligence or willful  misconduct of any
of such  Landlord's  Indemnities.  Tenant  shall,  at its own cost and  expense,
defend any and all actions,  suits and proceedings  which may be brought against
the  aforesaid  parties with respect to the  foregoing or in which the aforesaid
parties may be  impleaded.  Tenant shall pay,  satisfy and discharge any and all
judgments,  orders and decrees  which may be  recovered  against  the  aforesaid
parties in connection  with the  foregoing.  The aforesaid  parties shall not be
liable or responsible for, and Tenant hereby releases the aforesaid parties from
all liability or  responsibility to Tenant or any person claiming by, through or
under Tenant, by way of subrogation or otherwise,  any injury, loss or damage to
any  property  in  or  around  the  Leased  Premises  or  to  Tenant's  business
irrespective of the cause of such injury,  loss or damage,  except to the extent
caused by the gross  negligence  or  intentional  wrongful  acts of  Landlord or
Landlord's employees,  agents, officers,  members, managers or contractors,  and
Tenant  shall  require its  insurer(s)  to include in all of Tenant's  insurance
policies which could give rise to a right of  subrogation  against the aforesaid
parties a clause or endorsement whereby the insurer(s) shall waive any rights of
subrogation  against the aforesaid parties as well as other tenants or occupants
of the Building. Tenant hereby makes such waiver on behalf of its insurer, which
insurer, by insuring Tenant as contemplated under this Lease, shall be deemed to
have  acknowledged  the  provisions  hereof.  UNLESS CAUSED BY THE NEGLIGENCE OR
WILLFUL  MISCONDUCT  OF TENANT OR ITS AGENTS,  EMPLOYEES OR  INVITEES,  LANDLORD
HEREBY AGREES TO INDEMNIFY AND HOLD  HARMLESS  TENANT AND ITS AGENTS,  OFFICERS,
EMPLOYEES  AND BUSINESS  INVITEES  FROM AND AGAINST ANY AND ALL CLAIMS,  LOSSES,
ACTIONS,  DAMAGES,  LIABILITIES  AND EXPENSES  (INCLUDING,  WITHOUT  LIMITATION,
ATTORNEYS'  FEES)  THAT (I)  ARISE  FROM OR ARE IN  CONNECTION  WITH  LANDLORD'S
POSSESSION, USE, OCCUPATION,  MANAGEMENT,  REPAIR, MAINTENANCE OR CONTROL OF THE
BUILDING,  THE COMMON AREAS, THE PARKING AREAS, OR ANY PORTION THEREOF,  OR (II)
ARISE  FROM  OR ARE IN  CONNECTION  WITH  ANY ACT OR  OMISSION  OF  LANDLORD  OR
LANDLORD'S AGENTS, CONTRACTORS,  EMPLOYEES OR INVITEES, OR (III) RESULT FROM ANY
DEFAULT,  BREACH,  VIOLATION OR  NON-PERFORMANCE  OF THIS LEASE OR ANY PROVISION
HEREIN BY LANDLORD, OR (IV) RESULT FROM ANY INJURY OR DEATH TO PERSONS OR DAMAGE
TO PROPERTY  SUSTAINED IN OR ABOUT THE COMMON  AREAS,  THE PARKING  AREAS OR THE
DEMISED  PREMISES OF OTHER TENANTS.  THE SCOPE OF THE FOREGOING  INDEMNIFICATION
OBLIGATION SHALL BE SUBJECT TO THE TERMS AND CONDITIONS  APPLICABLE TO TENANT IN
THE SECOND AND THIRD SENTENCES OF THIS SUBSECTION.

               (5) Coverage. Landlord makes no representation to Tenant that the
                   --------
limits or forms of coverage specified above or approved by Landlord are adequate
to insure Tenant's  property or Tenant's  obligations  under this Lease, and the
limits of any insurance  carried by Tenant shall not limit Tenant's  obligations
or liability under any indemnity  provision  included in this Lease or under any
other provision of this Lease.

          (b)  Landlord.  Landlord  shall  obtain  and keep in force a policy of
               --------
comprehensive  general liability  insurance with coverage against such risks and
in such amounts as Landlord deems reasonably advisable insuring Landlord against
liability arising out of the ownership, operation and management of the


                                       15
<PAGE>
Building.  Landlord  shall also obtain and keep in force during the Term of this
Lease  a  policy  or policies of "all risk" insurance covering loss or damage to
the  Building in the amount of not less than  the full replacement cost thereof,
as  determined  by Landlord from time to time.  The terms and conditions of said
policies  and  the  perils  and  risks  covered  thereby  shall be determined by
Landlord,  from  time to time, in Landlord's sole but reasonable discretion.  In
addition,  at Landlord's option, Landlord shall obtain and keep in force, during
the  Term  of  this  Lease, a policy of rental interruption insurance, with loss
payable to Landlord, which insurance shall, at Landlord's option, also cover all
Operating  Expenses.  Tenant  will  not be named as an additional insured in any
insurance  policies  carried by Landlord and shall have no right to any proceeds
therefrom.  At Landlord's option, Landlord may obtain insurance coverages and/or
bonds  related  to  the  operation  of the parking areas.  In addition, Landlord
shall  have  the  right  to  obtain  such additional insurance as is customarily
carried  by  owners  or  operators  of  other comparable office buildings in the
geographical area of the Building.  The policies purchased by the Landlord shall
contain  such  deductibles  as  Landlord  may determine.  In addition to amounts
payable  by  Tenant  in  accordance  with  Section 1(b)(9), Tenant shall pay any
increase  in  the  property  insurance  premiums  for the Building over what was
payable  immediately  prior  to  the  increase  to  the  extent  the increase is
specified  by  Landlord's  insurance  carrier  as being  caused by the nature of
Tenant's  occupancy of the Leased Premises, or any act or omission of Tenant, or
Tenant  shall  cease  the  activity  giving  rise  to  such  increase.

          (c)  Waiver of  Subrogation.  Landlord  waives  any and all  rights or
               ----------------------
recovery  against Tenant for or arising out of damage to, or destruction of, the
Building.  Landlord shall require its insurer(s) to include in all of Landlord's
insurance  policies which could give rise to a right of subrogation  against the
aforesaid parties a clause or endorsement whereby the insurer(s) shall waive any
rights  of  subrogation  against  the  aforesaid  as well as  other  tenants  or
occupants of the  Building.  Landlord  hereby makes such waiver on behalf of its
insurer,  which insurer,  by insuring Landlord as contemplated under this Lease,
shall be deemed to have acknowledged the provisions  hereof.  Neither Landlord's
nor Tenant's  waiver shall  relieve the other from  liability  under  Section 18
below  except to the extent such  waiving  party's  insurance  company  actually
satisfies the other party's  obligations under Section 18 in accordance with the
requirements of Section 18.

     8.   Damage by Fire or Other Casualty.
          --------------------------------

          Tenant  shall give  prompt  notice to  Landlord in case of any fire or
other damage to the Leased Premises.  If the Leased Premises or the Building are
damaged by fire or other  casualty,  Landlord  shall  diligently  and as soon as
practicable  after such damage occurs (taking into account the time necessary to
effectuate a satisfactory  settlement with Landlord's  insurance company) repair
such damage at its own expense,  and until such repairs have been  completed the
Basic Rent and  Additional  Charges shall be abated in proportion to the part of
the Leased  Premises which is rendered  untenantable or unusable in the ordinary
course of Tenant's  business (in no event shall  damage to any parking  areas be
deemed to render  the  Leased  Premises  untenantable).  However,  if  available
insurance  proceeds are  insufficient  or if the Leased Premises or the Building
are damaged by fire or other  casualty  to such an extent  that the  damage,  in
Landlord's  reasonable  opinion,  cannot be fully  repaired  within one  hundred
eighty  (180) days from the date such  damage  occurs,  Landlord  shall have the
right, in its sole and absolute  discretion,  to terminate this Lease.  Landlord
shall use reasonable  efforts within sixty (60) days (but in no event later than
ninety  (90)  days)  after the  occurrence  of such  damage to notify  Tenant in
writing  of the  estimated  length of time to repair or to rebuild  and  whether
Landlord shall terminate this Lease.  Notwithstanding the foregoing, if Landlord
shall  elect or be  obligated  to rebuild or repair the Leased  Premises  or the
Building,  but in good faith determines that the Leased Premises or the Building
cannot be rebuilt or  repaired  within two hundred ten (210) days after the date
of the occurrence of the damage,  without payment of overtime or other premiums,
and the  damage to the  Building  has  rendered  the Leased  Premises  wholly or
partially  unusable or  inaccessible,  Landlord  shall notify Tenant  thereof in
writing at the time of Landlord's election to rebuild or repair and Tenant shall
thereafter  have a period of fifteen (15)  business days within which Tenant may
elect to  terminate  this Lease,  upon written  notice to  Landlord.  Failure of
Tenant to exercise  said  election  within said fifteen (15) business day period
shall  constitute  Tenant's  agreement to accept delivery of the Leased Premises
under this Lease whenever tendered by Landlord, provided Landlord thereafter


                                       16
<PAGE>
pursues  reconstruction  or  restoration  diligently  to  completion, subject to
delays  beyond Landlord's reasonable control.  Notwithstanding the foregoing, if
the  fire  or other casualty shall be caused by the  GROSS negligence or WILLFUL
MISCONDUCT  of Tenant or its agents or employees, Tenant shall remain liable for
the  full  amount  of the Basic Rent and Additional Charges during the period of
restoration  or  until termination of this Lease, and all required repairs shall
be  made  at  Tenant's  expense  to  the  extent  not  covered  by  insurance.

     9.   Condemnation.
          ------------

          If  a  substantial   portion  of  the  Leased  Premises,   or  all  or
substantially all of the Building (or the use or possession  thereof),  shall be
taken in condemnation proceedings or by exercise of any right of eminent domain,
or by a private  purchase in lieu thereof,  then this Lease shall  terminate and
expire on the date of such taking or  purchase  and Tenant  shall,  in all other
respects,  keep,  observe  and  perform  all  the  other  terms,  covenants  and
conditions of this Lease up to the date of such taking.  The net proceeds of any
award or other  compensation  payable in connection with such taking or purchase
shall be paid to  Landlord,  and Tenant  hereby  assigns to Landlord  all of its
right, title and interest in and to such award or other  compensation  except to
the extent it is related to Tenant's personal property,  to improvements made to
the Leased Premises or to Tenant's moving  expenses or other  relocation  costs.
Tenant shall have no claim  against  Landlord for the value (if any) of personal
property in the Leased Premises or the unexpired Term.  Tenant shall be entitled
to any  separate  award  for loss of or damage to  Tenant's  removable  personal
property and for moving expenses.

     10.  Assignment and Subletting.
          -------------------------

          (a) Landlord's  Consent  Required.  Tenant shall not voluntarily or by
              -----------------------------
operation of law assign, transfer,  hypothecate,  mortgage, sublet, or otherwise
transfer  or encumber  all or any part of Tenant's  interest in this Lease or in
the Leased Premises (hereinafter collectively a "Transfer"),  without Landlord's
prior written consent,  which shall not be unreasonably delayed,  conditioned or
withheld.  Landlord  shall  respond to  Tenant's  written  request  for  consent
hereunder  within  twenty  (20) days after  Landlord's  receipt  of the  written
request from Tenant.  Any attempted  Transfer without such consent shall be void
and shall  constitute  a material  default  and breach of this  Lease.  Tenant's
written request for Landlord's consent shall include, and Landlord's twenty (20)
day  response  period  referred  to above shall not  commence,  unless and until
Landlord  has  received  from  Tenant,  all of the  following  information:  (i)
financial  statements for the proposed  assignee or subtenant for the past three
(3) years, if available,  (ii) federal tax returns for the proposed  assignee or
subtenant for the past three (3) years, if available,  (iii) a TRW credit report
or  similar  report on the  proposed  assignee  or  subtenant,  (iv) a  detailed
description of the business the assignee or subtenant  intends to operate at the
Leased Premises,  (v) the proposed effective date of the assignment or sublease,
(vi) a copy of the proposed sublease or assignment  agreement which includes all
of the terms and  conditions  of the proposed  assignment  or sublease,  (vii) a
detailed description of any ownership or commercial  relationship between Tenant
and the proposed assignee or subtenant, and (viii) a detailed description of any
Alterations the proposed  assignee or subtenant desires to initially make to the
Leased Premises.  If the obligations of the proposed  assignee or subtenant will
be guaranteed  by any person or entity,  Tenant's  written  request shall not be
considered  complete until the  information  described in (i), (ii) and (iii) of
the previous sentence has been provided with respect to each proposed guarantor.
"Transfer" shall also include the transfer (i) if Tenant is a corporation, other
than a professional corporation,  and Tenant's stock is not publicly traded over
a recognized securities exchange, of more than fifty percent (50%) of the voting
stock of such  corporation  during the Term of this Lease (whether or not in one
or more transfers) or the dissolution, merger or liquidation of the corporation,
or (ii) if Tenant is a  partnership  or other entity of more than fifty  percent
(50%) of the profit and loss  participation in such partnership or entity during
the  Term  of  this  Lease  (whether  or not in one or  more  transfers)  or the
dissolution,  merger or liquidation of the partnership or entity. If Tenant is a
limited  or  general  partnership  (or is  comprised  of two  or  more  persons,
individually  or as  co-partners),  Tenant  shall not be  entitled  to change or
convert to (i) a limited liability company, (ii) a limited liability partnership
or (iii) any  other  entity  which  possesses  the  characteristics  of  limited
liability without the prior written consent of Landlord, which consent shall not
be unreasonably withheld, it being deemed reasonable for Landlord to withhold


                                       17
<PAGE>
its  consent to any such conversion if in Landlord's determination the financial
condition  of  the  new  entity is such that it will not reasonably be likely to
fulfill  the  Tenant's  remaining  obligations  under  the Lease.  Tenant's sole
remedy  in  the  event  that  Landlord  shall  wrongfully withhold consent to or
disapprove any assignment or sublease shall be (i) to obtain an order by a court
of  competent  jurisdiction  that Landlord grant such consent, or (ii) to submit
such  dispute  to  arbitration  as provided below; in no event shall Landlord be
liable  for  damages  with respect to its granting or withholding consent to any
proposed  assignment  or  sublease.  Tenant  shall  have  the  right to submit a
dispute  relating to whether Landlord shall have been reasonable in withholding,
conditioning or delaying its consent to any proposed assignment or subleasing by
Tenant  (an  "Assignment/Subletting  Dispute")  to binding expedited arbitration
              ------------------------------
under  the  Commercial  Arbitration  Rules  (the "AAA Rules") of the AAA, and in
particular,  the  Expedited  Procedures  provisions  (Rules 53 through 57 in the
January  1,  1993  edition)  of  such Commercial Arbitration Rules.  If Landlord
shall  exercise  any  option  to  recapture the Leased Premises, or shall deny a
request  for  consent  to  a  proposed  assignment  or  sublease,  Tenant  shall
indemnify,  defend  and  hold  Landlord  harmless  from  and against any and all
losses, liabilities, damages, costs and claims that may be made against Landlord
by  the  proposed  assignee  or  subtenant,  or  by any brokers or other persons
claiming  a  commission  or similar compensation in connection with the proposed
assignment  or  sublease.

          (b) Leveraged Buy-Out.  The involvement by Tenant or its assets in any
              -----------------
transaction,  or series of transactions  (by way of merger,  sale,  acquisition,
financing, refinancing, transfer, leveraged buy-out or otherwise) whether or not
a formal  assignment or  hypothecation  of this Lease or Tenant's assets occurs,
which  results or will  result in a  reduction  of the "Net  Worth" of Tenant as
hereinafter  defined,  by an amount equal to or greater than twenty-five percent
(25%) of such Net Worth of Tenant as it is  represented  to Landlord at the time
of the execution by Landlord of this Lease, or as it exists immediately prior to
said transaction or transactions  constituting such reduction, at whichever time
said Net  Worth of  Tenant  was or is  greater,  shall  be  considered  to be an
assignment of this Lease by Tenant to which Landlord may reasonably withhold its
consent.  "Net Worth" of Tenant for  purposes of this  Section 9(b) shall be the
net worth of Tenant  (excluding  any  guarantors)  established  under  generally
accepted accounting principles consistently applied.

          (c) Standard For Approval.  Landlord shall not  unreasonably  withhold
              ---------------------
its consent to a Transfer  provided that Tenant has complied with each and every
requirement,  term and  condition of this Section 10.  Tenant  acknowledges  and
agrees  that  each  requirement,  term and  condition  in this  Section  10 is a
reasonable  requirement,  term or condition.  It shall be deemed  reasonable for
Landlord to  withhold  its  consent to a Transfer  if any  requirement,  term or
condition  of this Section 10 is not  complied  with or: (i) the Transfer  would
cause  Landlord to be in violation of its  obligations  under  another  lease or
agreement to which Landlord is a party; (ii) in Landlord's  reasonable judgment,
a proposed  assignee  has a smaller  net worth than  Tenant had on the date this
Lease was entered into with Tenant or is less able  financially to pay the rents
due under  this  Lease as and when they are due and  payable;  (iii) a  proposed
assignee's or  subtenant's  business will impose an  unreasonable  burden on the
Building's  parking  facilities,  elevators,  Common Areas or utilities  that is
greater than the burden imposed by Tenant,  in Landlord's  reasonable  judgment;
(iv) the terms of a proposed  assignment or  subletting  will allow the proposed
assignee or subtenant to exercise a right of renewal, right of expansion,  right
of first offer,  right of first refusal or similar  right held by Tenant;  (v) a
proposed  assignee  or  subtenant  refuses  to enter  into a written  assignment
agreement or sublease,  reasonably satisfactory to Landlord, which provides that
it will abide by and assume all of the  applicable  terms and conditions of this
Lease for the term of any assignment or sublease and containing such other terms
and  conditions  as Landlord  reasonably  deems  necessary;  (vi) the use of the
Leased  Premises by the proposed  assignee or subtenant  will not be for the use
permitted by this Lease; (vii) any guarantor of this Lease refuses to consent to
the Transfer or to execute a written agreement reaffirming the guaranty;  (viii)
Tenant is in default as defined in Section 11 at the time of the  request;  (ix)
if  requested  by  Landlord,  the  assignee  or  subtenant  refuses  to  sign  a
non-disturbance  and attornment  agreement in favor of Landlord's lender in form
and substance  substantially  similar to that signed by Tenant; (x) Landlord has
sued or been sued by the proposed  assignee or subtenant or has  otherwise  been
involved in a legal dispute with the proposed assignee or subtenant; (xi) the


                                       18
<PAGE>
assignee or subtenant is involved in a business which is not in keeping with the
then current standards of the Building; (xii) the proposed assignee or subtenant
is  an  existing  tenant of the Building which Landlord has the capacity to, and
desires  to,  expand  or  relocate in the Building or is a person or entity then
negotiating  with  Landlord  for  the lease of space in the Building; (xiii) the
assignment  or  sublease  will  result  in  the Leased Premises being used as an
executive  suite;  or  (xiv)  the  assignee  or  subtenant  is a governmental or
quasi-governmental  entity  or  an  agency,  department  or instrumentality of a
governmental  or  quasi-governmental  agency.

          (d)  Additional   Terms  and  Conditions.   The  following  terms  and
               -----------------------------------
conditions shall be applicable to any Transfer:

               (1) Regardless of Landlord's  consent,  no Transfer shall release
Tenant from  Tenant's  obligations  hereunder or alter the primary  liability of
Tenant to pay the rent and other sums due Landlord  hereunder and to perform all
other  obligations to be performed by Tenant  hereunder or release any guarantor
from its obligations under its guaranty.

               (2)  Landlord  may accept rent from any person  other than Tenant
pending approval or disapproval of an assignment or subletting.

               (3) Neither a delay in the approval or disapproval of a Transfer,
nor the acceptance of rent,  shall constitute a waiver or estoppel of Landlord's
right to exercise  its rights and remedies for the breach of any of the terms or
conditions of this Section 10.

               (4) The consent by Landlord to any Transfer  shall not constitute
a  consent  to  any  subsequent  Transfer  by  Tenant  or to any  subsequent  or
successive Transfer by an assignee or subtenant.  However,  Landlord may consent
to subsequent  Transfers or any  amendments  or  modifications  thereto  without
notifying Tenant or anyone else liable on the Lease and without  obtaining their
consent,  and such action shall not relieve such  persons from  liability  under
this Lease.

               (5) In the event of any default  under this Lease,  Landlord  may
proceed directly  against Tenant,  any guarantors or anyone else responsible for
the  performance  of this Lease,  including any  subtenant or assignee,  without
first  exhausting  Landlord's  remedies  against  any  other  person  or  entity
responsible therefor to Landlord, or any security held by Landlord.

               (6)  Landlord's  written  consent to any Transfer by Tenant shall
not  constitute an  acknowledgment  that no default then exists under this Lease
nor shall such consent be deemed a waiver of any then existing default.

               (7) The discovery of the fact that any financial statement relied
upon by Landlord in giving its consent to an assignment  or  subletting  was, to
Tenant's  actual  knowledge,  materially  false shall,  at Landlord's  election,
render Landlord's consent null and void.

               (8)  Landlord  shall not be liable to any  subtenant  under  this
Lease or under any sublease.

               (9) No assignment or sublease may be modified or amended  without
Landlord's prior written consent, such consent not to be unreasonably  withheld,
conditioned or delayed.

               (10) The  occurrence of a transaction  described in Section 10(b)
shall give  Landlord the right (but not the  obligation)  to require that Tenant
immediately  provide  Landlord with an additional  Security Deposit in an amount
reasonably determined by Landlord to protect Landlord's interests hereunder, and
Landlord may make its receipt of such amount a condition to  Landlord's  consent
to such transaction.

               (11) Any assignee of, or subtenant  under,  this Lease shall,  by
reason of accepting such assignment or entering into such sublease (with respect
to the sublet space),  be deemed,  for the benefit of Landlord,  to have assumed
and


                                       19
<PAGE>
agreed  to  conform and comply with each and every term, covenant, condition and
obligation  herein to be observed or performed by Tenant during the term of said
assignment  or  sublease,  other  than  such  obligations  as  are  contrary  or
inconsistent  with provisions of an assignment or sublease to which Landlord has
specifically  consented  in  writing.

          (e)  Additional  Terms and Conditions  Applicable to  Subletting.  The
               -----------------------------------------------------------
following terms and conditions shall apply to any subletting by Tenant of all or
any part of the Leased  Premises and shall be deemed  included in all  subleases
under this Lease whether or not expressly incorporated therein:

               (1) Tenant  hereby  absolutely  and  unconditionally  assigns and
transfers to Landlord all of Tenant's interest in all rentals and income arising
from any sublease entered into by Tenant, and Landlord may collect such rent and
income and apply same toward Tenant's  obligations  under this Lease;  provided,
however, that until an Event of Default shall occur under this Lease, Tenant may
receive,  collect and enjoy the rents  accruing  under such  sublease.  Landlord
shall not, by reason of this or any other  assignment  of such rents to Landlord
nor by reason of the collection of the rents from a subtenant, be deemed to have
assumed or  recognized  any  sublease or to be liable to the  subtenant  for any
failure of Tenant to perform and comply with any of Tenant's obligations to such
subtenant  under  such  sublease,   including,  but  not  limited  to,  Tenant's
obligation to return any Security Deposit.  Tenant hereby irrevocably authorizes
and directs any such  subtenant,  upon receipt of a written notice from Landlord
stating that an Event of Default exists under this Lease, to pay to Landlord the
rents due as they  become  due  under  the  sublease.  Tenant  agrees  that such
subtenant  shall have the right to rely upon any such statement and request from
Landlord,  and that such subtenant shall pay such rents to Landlord  without any
obligation  or  right  to  inquire  as  to  whether  such  default   exists  and
notwithstanding any notice from or claim from Tenant to the contrary.

               (2) In the event  Tenant  shall  default  beyond  any  applicable
notice and cure periods in the performance of its obligations  under this Lease,
Landlord  at its option and  without  any  obligation  to do so, may require any
subtenant to attorn to Landlord,  in which event  Landlord  shall  undertake the
obligations  of Tenant under such sublease from the time of the exercise of said
option to the termination of such sublease;  provided,  however,  Landlord shall
not be liable for any prepaid rents or Security  Deposit paid by such  subtenant
to Tenant not  delivered  to Landlord or for any other prior  defaults of Tenant
under such sublease.

     (f)     Transfer  Premium from Assignment or Subletting.  Landlord shall be
             -----------------------------------------------
entitled  to  receive from Tenant (as and when received by Tenant) as an item of
additional  rent  fifty percent (50%) of all amounts received by Tenant from any
subtenant  or  assignee  in  excess of the amounts payable by Tenant to Landlord
hereunder  (hereinafter  the  "Transfer  Premium").  Landlord shall not have the
right  to  receive the Transfer Premium in the event of a sublease or assignment
to  a  Permitted  Transferee,  as defined in Section 10(i) AND PROVIDED FURTHER,
THAT  LANDLORD  SHALL  NOT HAVE THE RIGHT TO RECEIVE THE TRANSFER PREMIUM IN THE
EVENT  OF  A  SUBLEASE  OF  LESS  THAN  TWENTY-FIVE  PERCENT (25%) OF THE LEASED
PREMISES  FOR  FURNISHED  OFFICE  SPACE TO A SUBTENANT THAT RECEIVES SECRETARIAL
SUPPORT  SERVICES  FROM  TENANT  AS  PART OF THE SUBLEASE AGREEMENT (HEREINAFTER
REFERRED  TO  AS A "PERMITTED SUBLEASE").  The Transfer Premium shall be reduced
by  the  reasonable  and  customary  costs  incurred  by  Tenant  to effect such
assignment  or  subletting,  to  include  brokerage fees and commissions, tenant
improvement  costs,  marketing  costs, tenant allowances and legal fees actually
paid by Tenant in order to assign the Lease or to sublet a portion of the Leased
Premises.  For  purposes  of calculating the Transfer Premium, all expenses will
be  amortized  over the life of such sublease. "Transfer Premium" shall mean all
Basic  Rent,  Additional  Charges  or other consideration of any type whatsoever
payable  by the assignee or subtenant in excess of the Basic Rent and Additional
Charges  payable  by  Tenant  under  this Lease.  If less than all of the Leased
Premises  is  transferred,  the  Basic  Rent and the Additional Charges shall be
determined  on  a  per  rentable square foot basis.  Transfer Premium shall also
include,  but  not be limited to, key money and bonus money paid by the assignee
or  subtenant  to  Tenant  in  connection with such Transfer, and any payment in
excess  of  fair market value for services rendered by Tenant to the assignee or


                                       20
<PAGE>
subtenant  or  for  assets,  fixtures,  inventory,  equipment,  or  furniture
transferred  by  Tenant  to  the  assignee  or subtenant in connection with such
Transfer.  For  purposes  of  calculating the Transfer Premium, expenses will be
amortized  over  the  life  of  the  sublease.

          (g) Landlord's Option to Recapture Space.  Notwithstanding anything to
              ------------------------------------
the contrary  contained in this Section 10,  Landlord shall have the option,  by
giving  written  notice to Tenant  within  twenty (20) days after receipt of any
request by Tenant to either (i) assign this Lease to any person or entity  other
than a Permitted  Transferee,  or (ii) sublease space in the Leased  Premises to
any person or entity other than a Permitted Transferee,  to terminate this Lease
with  respect  to all but not less than all of said  space  effective  as of the
proposed  transfer  date but in no event  earlier  than  thirty  (30) days after
Landlord's  election;  PROVIDED,  HOWEVER,  THAT  TENANT  SHALL  HAVE  THREE (3)
BUSINESS  DAYS  FOLLOWING  NOTICE BY LANDLORD OF ITS ELECTION TO RECAPTURE  SAID
SPACE TO RESCIND ITS REQUEST TO ASSIGN OR SUBLEASE.  In the event of a recapture
by  Landlord,  if this Lease  shall be  canceled  with  respect to less than the
entire  Leased  Premises,  the  Tenant  shall be  released  from this Lease with
respect  to the space  recaptured  by  Landlord  (except  to the extent any such
obligations by their terms survive  termination of this Lease),  the Basic Rent,
Tenant's  Proportionate  Share of Operating  Expense increases and the number of
parking  spaces  Tenant may use shall be  adjusted on the basis of the number of
rentable  square feet retained by Tenant in proportion to the number of rentable
square feet  contained in the  original  Leased  Premises,  and this Lease as so
amended shall continue  thereafter in full force and effect with respect to that
portion of the Leased  Premises  retained by Tenant,  and upon request of either
party,  the parties  shall  execute  written  confirmation  of same. If Landlord
recaptures only a portion of the Leased  Premises,  it shall construct and erect
at its sole cost such  partitions  as may be  required  to demise  and sever the
space to be retained by Tenant from the space  recaptured by Landlord.  Landlord
may, at its option,  lease any recaptured  portion of the Leased Premises to the
proposed  subtenant  or  assignee  or to any  other  person  or  entity  without
liability to Tenant.  Tenant shall not be entitled to any portion of the profit,
if any,  Landlord  may  realize on account of such  termination  and  reletting.
Tenant acknowledges that the purpose of this Section 10(g) is to enable Landlord
to  receive  profit  in the form of  higher  rent or other  consideration  to be
received  from an assignee or  sublessee,  to give  Landlord the ability to meet
additional  space  requirements  of other  tenants of the Building and to permit
Landlord to control the leasing of space in the  Building.  Tenant  acknowledges
and  agrees  that  the  requirements  of this  Section  10(g)  are  commercially
reasonable  and are  consistent  with the  intentions  of  Landlord  and Tenant.
NOTWITHSTANDING THE FOREGOING,  LANDLORD'S RIGHT TO RECAPTURE SHALL NOT APPLY TO
ANY PERMITTED SUBLEASE AS THAT TERM IS DEFINED IN SECTION 10(F) HEREINABOVE.

          (h) Landlord's  Expenses.  In the event Tenant shall assign this Lease
              --------------------
or sublet the  Leased  Premises  or  request  the  consent  of  Landlord  to any
Transfer,  then  Tenant  shall pay  Landlord's  reasonable  costs  and  expenses
incurred in connection  therewith,  including,  but not limited to,  attorneys',
architects',  accountants', engineers' or other consultants' fees. SUCH EXPENSES
SHALL NOT EXCEED ONE THOUSAND FIVE HUNDRED AND NO/100  DOLLARS  ($1,500.00)  PER
TRANSFER OR REQUEST TO TRANSFER.

          (i) Permitted Transactions.  NOTWITHSTANDING  ANYTHING TO THE CONTRARY
              ----------------------
CONTAINED IN THIS SECTION 10,  TENANT SHALL HAVE THE RIGHT,  WITHOUT  LANDLORD'S
CONSENT, UPON THIRTY (30) DAYS ADVANCE WRITTEN NOTICE TO LANDLORD, TO ASSIGN THE
LEASE OR SUBLET THE WHOLE OR ANY PART OF THE LEASED  PREMISES TO ANY ENTITY THAT
CONTROLS,  IS  CONTROLLED  BY OR IS  UNDER  COMMON  CONTROL  WITH  TENANT  OR IN
CONNECTION WITH ANY  CONSOLIDATION OR  REORGANIZATION OF TENANT OR THE MERGER OF
TENANT WITH ANY OTHER ENTITY OR THE SALE OF ALL OR SUBSTANTIALLY ALL OF TENANT'S
ASSETS OR OF ALL OR SUBSTANTIALLY ALL OF THE INTERESTS  (PARTNERSHIP,  STOCK, OR
OTHERWISE)  IN  TENANT  (EACH  OF THE  TRANSACTIONS  REFERENCED  ABOVE  IN  THIS
SUBPARAGRAPH (I) ARE HEREINAFTER  REFERRED TO AS A "PERMITTED TRANSFER" AND EACH
SURVIVING ENTITY SHALL HEREINAFTER BE REFERRED TO AS A "PERMITTED  TRANSFEREE");
PROVIDED THAT SUCH PERMITTED TRANSFER IS SUBJECT TO THE FOLLOWING CONDITIONS:

               (i) TENANT, TO THE EXTENT TENANT SURVIVES SUCH TRANSACTION, SHALL
REMAIN FULLY LIABLE UNDER THE TERMS AND CONDITIONS OF THE LEASE;


                                       21
<PAGE>
               (ii) ANY SUCH PERMITTED TRANSFEREE SHALL BE SUBJECT TO ALL OF THE
TERMS,  COVENANTS,  AND CONDITIONS OF THE LEASE EXCEPT AS OTHERWISE SPECIFICALLY
PROVIDED IN THIS LEASE;

               (iii)  ANY  SUCH  PERMITTED   TRANSFEREE  EXPRESSLY  ASSUMES  THE
OBLIGATIONS OF TENANT UNDER THE LEASE;

               (iv) SUCH PERMITTED  TRANSFEREE HAS A NET WORTH AT LEAST EQUAL TO
THE NET WORTH OF TENANT AS OF THE DATE OF THIS LEASE.

     11.  Default Provisions.
          ------------------

          (a) Events of Default. Each of the following events shall be deemed to
              -----------------
be a default under this Lease,  and is referred to in this Lease as an "Event of
Default":

               (1) A default  by Tenant in the due and  punctual  payment of any
Basic Rent or Additional  Charges (other than those Additional Charges for which
Landlord  must give  Tenant  notice in which case  subparagraph  (2) below shall
apply)  which  continues  for more than five (5)  business  days after  LANDLORD
DELIVERS  WRITTEN NOTICE THAT such Basic Rent or Additional  Charges IS PAST due
and  payable;  PROVIDED,  HOWEVER,  IT SHALL BE AN  EVENT OF  DEFAULT  HEREUNDER
WITHOUT ANY  OBLIGATION OF LANDLORD TO GIVE ANY NOTICE TO TENANT IF LANDLORD HAS
PREVIOUSLY GIVEN TENANT TWO (2) NOTICES PURSUANT TO THIS SECTION 11(A)(1) DURING
THE EIGHTEEN (18) MONTH PERIOD PRECEDING SUCH DEFAULT; or

               (2) A  default  by  Tenant  in the due and  punctual  payment  of
Additional  Charges  which  continues for more than five (5) business days after
the payment date set forth in the notice of payment, where required, by Landlord
to Tenant; or

               (3) The neglect or failure of Tenant to perform or observe any of
the terms,  covenants or conditions  contained in this Lease on Tenant's part to
be performed or observed  other than those  referred to above in subsection  (1)
which is not remedied by Tenant  within  twenty (20) days after  Landlord  shall
have given to Tenant  written  notice  specifying  such  neglect or failure or a
reasonable time after written notice if such failure is incapable of cure within
twenty (20) days, so long as Tenant pursues the cure with due diligence; or

               (4) The assignment,  transfer,  mortgaging or encumbering of this
Lease or the  subletting  of the Leased  Premises in a manner not  permitted  by
Section 10 hereof; or

               (5) The taking of this Lease or the Leased Premises,  or any part
thereof,  upon execution or by other process of law directed against Tenant,  or
upon or


                                       22
<PAGE>
subject  to  any  attachment  at  the  insistence of any creditor of or claimant
against  Tenant,  which  execution  or  attachment  shall  not  be discharged or
disposed of within thirty (30) days after the levy thereof, or the occurrence of
any  of  the  events  listed  in  Section  12  hereof;  or

               (6) ANY abandonment of the Leased Premises by Tenant.

          (b)  Remedies.  Upon five (5)  calendar  days notice from  Landlord to
               --------
Tenant of an Event of Default under Section 11(a)(1) above, or the occurrence of
any other Event of Default, Landlord shall have the right, at its election, then
or at any time thereafter while such Event of Default shall continue, either:

               (1) To give Tenant  written notice that this Lease will terminate
on a date to be  specified  in such  notice,  which  date shall not be less than
three (3) days after  such  notice,  and on the date  specified  in such  notice
Tenant's  right to possession of the Leased  Premises shall cease and this Lease
shall thereupon be terminated,  but Tenant shall remain liable as provided below
in subsection (c); or,

               (2) Without demand or notice,  to re-enter and take possession of
the  Leased  Premises,  or any  part  thereof,  and  repossess  the  same  as of
Landlord's  former estate and expel Tenant and those  claiming  through or under
Tenant and  remove its or their  effects,  either by summary  proceedings  or by
action at law or in equity or by self-help (if necessary) or otherwise,  without
being  deemed  guilty of any manner of  trespass  and without  prejudice  to any
remedies for arrears of rent or preceding breach of covenant. If Landlord elects
to re-enter under this  subsection (2),  Landlord may terminate this Lease,  or,
from time to time, without terminating this Lease but terminating Tenant's right
to occupy  the  Leased  Premises,  may relet the  Leased  Premises,  or any part
thereof,  as agent  for  Tenant  for such  term or terms  and at such  rental or
rentals and upon such other terms and conditions as Landlord may deem advisable,
with  the  right  to make  reasonable  alterations  and  repairs  to the  Leased
Premises.  No such re-entry or taking of  possession  of the Leased  Premises by
Landlord shall be construed as an election on Landlord's  part to terminate this
Lease unless a written  notice of such  intention is given to Tenant under above
subsection  (1) or unless  the  termination  thereof  be  decreed  by a court of
competent jurisdiction.  Tenant waives any right to the service of any notice of
Landlord's intention to re-enter provided for by any present or future law.

          (c) Damages.  If Landlord  terminates  this Lease or Tenant's right to
              -------
occupy  the  Leased  Premises  pursuant  to above  subsection  (b),  subject  to
Landlord's  obligation to expend  commercially  reasonable  efforts to relet the
Leased  Premises  and  mitigate its  damages,  (however  Landlord  shall have no
obligation  to relet the Leased  Premises if other  vacant space is available in
the Building) Tenant shall remain liable (in addition to accrued liabilities) to
the extent legally permissible for (i) (A) all Basic Rent and Additional Charges
provided for in this Lease until the date this Lease would have expired had such
termination  not  occurred,  discounted to present value at the discount rate of
the Federal Reserve Bank of Baltimore at the time of such  termination  plus one
percent (1%), all accelerated to the date of any such termination  ("NPV"),  and
(B) any and all  reasonable  expenses  incurred by Landlord in  re-entering  the
Leased  Premises,  repossessing  the same,  making  good any  default of Tenant,
remodeling,  altering or dividing the Leased  Premises for relet,  combining the
same with any  adjacent  space for any new  tenants,  putting the same in proper
repair,  establishing  signage for,  reletting the same  (including  any and all
reasonable  attorneys  fees and  disbursements  and  reasonable  brokerage  fees
incurred in so doing),  and any and all  expenses  which  Landlord  may incur in
reletting  the Leased  Premises;  less (ii) the net proceeds of any reletting of
the Leased  Premises  discounted  to NPV.  Tenant  agrees to pay to Landlord the
difference between items (i) and (ii) above,  within ten (10) days after notice,
upon any  termination  or  subletting,  in full or, at Landlord's  option,  with
respect  to each  month  during  the Term,  at the end of such  month.  Any suit
brought by Landlord to enforce  collection of such  difference for any one month
shall not prejudice Landlord's right to enforce the collection of any difference
for any other month. In addition to the foregoing,  Tenant shall pay to Landlord
such sums as the court which has jurisdiction  thereover may adjudge  reasonable
as attorneys fees with respect to any  successful law suit or action  instituted
by Landlord to enforce the  provisions  of this Lease.  Landlord  shall have the
right, at its sole option, to relet the whole or any part of the Leased Premises


                                       23
<PAGE>
for the whole of the unexpired Term, or longer, or from time to time for shorter
periods,  for  any  rental  then obtainable, giving such concessions of rent and
making  such  special repairs, alterations, decorations and painting for any new
tenant  as  Landlord,  in  its sole and absolute discretion, may deem advisable.
Landlord  shall  be  under no obligation to relet the Leased Premises.  Tenant's
liability  as aforesaid shall survive the institution of summary proceedings and
the  issuance  of  any  warrant  thereunder  unless  waived.

          (d) Basic Rent and  Additional  Charges.  If Tenant fails to pay Basic
              -----------------------------------
Rent or any  Additional  Charges due hereunder on the date it is due, then after
Tenant's  second  failure to pay any such monetary  obligation on the date it is
due (after  expiration of any applicable  notice and grace period) in any twelve
(12) month period, and at Landlord's option,  Landlord may require Tenant to pay
six (6) months of Basic Rent and Additional Charges in advance.

     12.  Bankruptcy Termination Provision.
          --------------------------------

     This  Lease  shall, at Landlord's option, terminate and expire, without the
performance  of  any  act  or  the  giving  of  any notice by Landlord, upon the
occurrence  of  any  of the following events:  (1) Tenant's inability to pay its
debts  generally  as  they  become  due,  or (2) the commencement by Tenant of a
voluntary  case  under  the  federal  bankruptcy  laws,  as  now  constituted or
hereafter  amended,  or  any  other  applicable  federal  or  state  bankruptcy,
insolvency  or  other  similar  law,  or  (3) the entry of a decree or order for
relief by a court having jurisdiction in the premises in respect of Tenant in an
involuntary  case  under  the  federal  bankruptcy  laws,  as now constituted or
hereafter  amended,  or  any  other  applicable  federal  or  state  bankruptcy,
insolvency or other similar law, and the continuance of any such decree or order
unstayed  and  in  effect  for  a  period of sixty (60) consecutive days, or (4)
Tenant's  making  an assignment of all or a substantial part of its property for
the  benefit  of  its  creditors,  or  (5)  Tenant's seeking or consenting to or
acquiescing  in  the appointment of, or the taking of possession by, a receiver,
trustee  or  custodian for all or a substantial part of its property, or (6) the
entry  of  a  court  order  without  Tenant's  consent, which order shall not be
vacated,  set  aside  or  stayed  within sixty (60) days from the date of entry,
appointing a receiver, trustee or custodian for all or a substantial part of its
property, (7) the sale of all or substantially all of Tenant's assets OTHER THAN
PURSUANT  TO  A  PERMITTED TRANSFER, or (8) any of the foregoing events by or as
against  any Guarantor.  In the event of termination of the Lease as a result of
any  of the foregoing events, Landlord shall be entitled to damages as set forth
in  Section  11(c) hereof.  The provisions of this Section 12 shall be construed
with  due  recognition  for the provisions of the federal bankruptcy laws, where
applicable,  but shall be interpreted in a manner which results in a termination
of  this  Lease in each and every instance, and to the fullest extent and at the
earliest moment, that such termination is permitted under the federal bankruptcy
laws, it being of prime importance to the Landlord to deal only with Tenants who
have,  and continue to have, a strong degree of financial strength and financial
stability.

     13.  Landlord May Perform Tenant's Obligations.
          -----------------------------------------

     If  Tenant shall fail to keep or perform any of its obligations as provided
in  this  Lease  in  respect  to  (a)  maintenance of insurance, (b) repairs and
maintenance of the Leased Premises, (c) compliance with the Requirements, or (d)
the  making  of  any  other payment or performance of any other obligation, then
Landlord  may (but shall not be obligated to do so) upon the continuance of such
failure on Tenant's part for twenty (20) days after written notice to Tenant (or
after  such  additional period, if any, as Tenant may reasonably require to cure
such  failure  if  of a nature which cannot be cured within said twenty (20) day
period)  and  without waiving or releasing Tenant from any obligation, and as an
additional  but  not exclusive remedy, make any such payment or perform any such
obligation,  and all sums so paid by Landlord and all necessary incidental costs
and  expenses,  including  attorneys  fees,  incurred by Landlord in making such
payment  or  performing  such  obligation, together with interest thereon at the
rate  specified in Section 3(c) hereof from the date of payment, shall be deemed
an  Additional  Charge and shall be paid to Landlord on demand, or at Landlord's
option  may  be  added to any installment of rent thereafter falling due, and if
not  so  paid  by Tenant, Landlord shall have the same rights and remedies as in
the  case  of  a  default  by  Tenant  in  the  payment  of  Rent.


                                       24
<PAGE>
     14.  Security Deposit.
          ----------------

          (a) Tenant shall  deposit  with  Landlord  the  Security  Deposit,  as
security  for the prompt,  full and faithful  performance  by Tenant of each and
every  provision of this Lease and of all obligations of Tenant  hereunder.  The
Security  Deposit  shall be in the  form of cash  or,  at  Tenant's  option,  an
irrevocable  letter of credit (the  "Security  Deposit  L/C").  If the  Security
Deposit is in the form of a letter of credit,  the Security Deposit L/C shall be
delivered to Landlord at Tenant's  sole cost and expense.  The Security  Deposit
L/C shall be issued by and drawn on a bank reasonably acceptable to Landlord, in
Landlord's  sole  but  reasonable   discretion,   and  shall  name  Landlord  as
Beneficiary.  If the maturity  date of the Security  Deposit L/C is prior to the
end of the Term of the Lease,  Tenant  shall renew the  Security  Deposit L/C as
often as is necessary with the same bank or financial  institution (or a similar
bank or financial  institution  reasonably  acceptable to Landlord) and upon the
same terms and conditions, not less than thirty (30) days prior to the purported
expiration  date of the Security  Deposit L/C. In the event that Tenant fails to
timely renew the Security  Deposit L/C as aforesaid,  Landlord shall be entitled
to draw  against the entire  amount of the  Security  Deposit  L/C. The Security
Deposit L/C shall be  assignable  by Landlord  and upon such  assignment  to any
party  assuming in writing the  landlord  interest  and  obligations  under this
Lease,  and  this  Landlord  shall be  relieved  from all  liability  to  Tenant
therefor.  If an Event of Default occurs,  Landlord may use, apply or retain the
whole or any part of the Security  Deposit for the payment of (i) any Basic Rent
or  Additional  Charges which Tenant shall not have paid or which may become due
after the occurrence of such Event of Default, (ii) any sum expended by Landlord
on Tenant's  behalf in accordance with the provisions of this Lease or (iii) any
other sum  which  Landlord  may  expend  or be  required  to expend by reason of
Tenant's default, including damages or deficiency in the reletting of the Leased
Premises as provided in Section 11 hereof. The use,  application or retention of
the Security  Deposit,  or any portion  thereof,  by Landlord  shall not prevent
Landlord from  exercising any other right or remedy provided by this Lease or by
law and shall not operate as a limitation on any recovery to which  Landlord may
otherwise be entitled.  If any portion of the Security Deposit is used,  applied
or retained by Landlord for the purposes set forth above, Tenant agrees,  within
ten (10) days after a written  demand  therefor is made by Landlord,  to deposit
cash or a new  Security  Deposit  L/C meeting the  criteria  referenced  in this
Section  14,  with  Landlord in an amount  sufficient  to restore  the  Security
Deposit to its original amount. If Tenant shall fully and faithfully comply with
all of the  provisions  of this  Lease,  the  Security  Deposit,  or any balance
thereof,  shall be returned to Tenant  within ten (10)  business  days after the
expiration of the Term, with interest.  In the absence of evidence  satisfactory
to Landlord of any  permitted  assignment  of the right to receive the  Security
Deposit,  or the  remaining  balance  thereof,  Landlord  may return the same to
Tenant, regardless of one or more assignments of Tenant's interest in this Lease
or the Security Deposit.  In such event, upon the return of the Security Deposit
(or  balance  thereof)  to Tenant,  Landlord  shall be  completely  relieved  of
liability  under  this  Section  14. In the event of a  transfer  of  Landlord's
interest in the Leased  Premises,  Landlord shall have the right to transfer the
Security Deposit to the transferee  thereof. In such event, upon the delivery by
Landlord to Tenant of such transferee's written acknowledgment of its receipt of
such Security  Deposit and its  agreement to comply with the  provisions of this
Lease,  Landlord  shall be  deemed  to have been  released  by  Tenant  from all
liability or  obligation  for the return of such  Security  Deposit,  and Tenant
agrees to look solely to such transferee for the return of the Security  Deposit
and the  transferee  shall be bound by all  provisions of this Lease relating to
the return of the Security Deposit. The Security Deposit shall not be mortgaged,
assigned or  encumbered  in any manner  whatsoever  by Tenant  without the prior
written consent of Landlord.

          (b)  Notwithstanding  anything to the contrary in this Section 14, and
provided that Tenant is not in monetary default beyond any applicable notice and
cure periods  under the Lease at the time of each  reduction,  the amount of the
Security  Deposit L/C OR THE CASH  SECURITY  DEPOSIT,  AS  APPLICABLE,  shall be
reduced by Seventeen Thousand Five Hundred Five and 76/100 Dollars ($17,505.76))
on each anniversary of the Lease Commencement Date.

     15.  Subordination; Attornment.
          --------------------------

          (a)  Subordination.  Subject to the  provisions  contained  in Section
               -------------
15(d),  this  Lease  and  Tenant's  interest  hereunder  shall  be  subject  and
subordinate  to each and  every  ground or  underlying  lease  now  existing  or
hereafter made of the entire Building and/or underlying land and to all


                                       25
<PAGE>
renewals, modifications, replacements and extensions thereof, and to the lien of
any  mortgage  now  or  hereafter placed upon the Building, and to all renewals,
modifications,  replacements,  consolidations  and extensions thereof and to any
and  all  advances made thereunder and the interest thereon.  Tenant agrees that
within  fifteen (15) days after written request therefor from Landlord, it will,
from time to time, execute and deliver any instrument or other document required
by  any such landlord or mortgagee to subordinate this Lease and its interest in
the Leased Premises to such lease or the lien of any such mortgage.  Tenant will
also  upon  request submit current financial statements and financial statements
covering  the two (2) immediately preceding years, and Tenant will upon request,
at  Landlord's  cost,  record  this Lease or a short form thereof if required by
Landlord's  mortgagee  or other lending institution but, otherwise, Tenant shall
not  record  this  Lease  or  a  short  form  thereof.

          (b)  Modifications.  In the event  that any bank,  insurance  company,
               -------------
university,  pension or welfare fund, savings and loan association,  real estate
investment  trust,  business  trust, or other  financial  institution  providing
financing  for the Building  requires,  as a condition of such  financing,  that
modifications  to this Lease be obtained,  and provided that such  modifications
(i) are reasonable,  (ii) do not materially adversely affect Tenant's use of the
Leased Premises as herein  permitted,  (iii) do not materially  adversely change
Tenant's  rights or obligations  under this Lease,  and (iv) do not increase the
rentals and other sums required to be paid by Tenant  hereunder,  Landlord shall
submit such required  modifications  to Tenant,  and Tenant shall enter into and
execute a written  amendment hereto  incorporating  such required  modifications
within  twenty  (20)  days  after  the same  have  been  submitted  to Tenant by
Landlord.  If Tenant  shall  fail to so enter  into and  execute  such a written
amendment, then Landlord shall thereafter have the right, at its sole option, to
submit  such  matter to  binding  expedited  arbitration  under  the  Commercial
Arbitration Rules of the AAA by giving Tenant written notice thereof.

          (c)  Attornment.  Subject to the provisions  contained in this Section
               ----------
15,  in the  event  of (a) a  transfer  of  Landlord's  interest  in the  Leased
Premises,  (b) the  termination of any ground or underlying  lease of the entire
Building  and/or  underlying  land,  or (c)  the  purchase  of the  Building  or
Landlord's  interest  therein  at a  foreclosure  sale  or by  deed  in  lieu of
foreclosure  under any mortgage or pursuant to a power of sale  contained in any
mortgage,  then in any of such events,  Tenant  shall,  at  Landlord's  request,
attorn to and  recognize the  transferee or purchaser of Landlord's  interest or
the landlord under the terminated  ground or underlying  lease,  as the case may
be, as landlord under this Lease for the balance then remaining of the Term, and
thereafter  this Lease shall continue as a direct lease between such person,  as
"Landlord", and Tenant, as "Tenant", but such landlord, transferee or purchaser,
unless an express assumption of this Lease is made by such landlord,  transferee
or purchaser, in which case Landlord shall be released from liability, shall not
be liable for any act or omission of Landlord prior to such lease termination or
prior to such  person's  succession  to title,  nor be  subject  to any  offset,
defense or  counterclaim  accruing  prior to such lease  termination or prior to
such person's  succession to title, nor be bound by any payment of Basic Rent or
Additional  Charges  prior to such lease  termination  or prior to such person's
succession  to title for more than one month in  advance.  Tenant  agrees  that,
within twenty (20) days after written request  therefor from Landlord,  it will,
from time to time, execute and deliver any instrument or other document required
by any mortgagee,  transferee,  purchaser or other interested  person to confirm
such attornment and/or such obligation to attorn.

          (d) Nondisturbance.  Notwithstanding  anything contained in Section 15
              --------------
of this Lease to the contrary:

                    a) If this  Lease  is  subordinate  to any  existing  fee or
leasehold  mortgages or ground or air space leases covering the underlying land,
Building or Common Areas, Landlord,  prior to the Lease Commencement Date, shall
obtain,   have   executed  and  shall  deliver  to  Tenant,   a   Subordination,
Nondisturbance and Attornment Agreement by and between the Tenant and such prior
party, in the form of Exhibit F attached to this Lease.
                      ---------

                    b) Subject to the  provision of subsection  (i) below,  this
Lease shall be subordinate and subject to any future fee or leasehold  Mortgages
and ground or air space leases covering the underlying land,  Building or Common
Areas.


                                       26
<PAGE>
                    (i) If any  Mortgage is  foreclosed  or ground  lease or air
                    space lease is terminated, then:

                         (1) This Lease shall continue in full force and effect,
                             and

                         (2) Tenant's  quiet  enjoyment  shall  not be disturbed
                             if Tenant  is not in  default  of this Lease beyond
                             any applicable  grace and notice period provided
                             herein for the cure thereof, and

                         (3) Tenant  shall  attorn to  and  recognize  the
                             mortgagee,  purchaser  at  a  foreclosure  sale  or
                             ground  or other lessor ("Successor  Landlord")  as
                             Tenant's landlord for the remaining Lease Term; and

                    (ii)  This  subsection  shall  be  self-operative;  however,
                    Landlord shall use commercially  reasonable efforts to cause
                    a future lender to enter into an agreement  confirming  such
                    subordination,  attornment  and  non-disturbance  if  either
                    party so requests.

     16.  Quiet Enjoyment.
          ---------------

          Landlord  covenants  that  Tenant,  upon paying the Basic Rent and the
Additional Charges provided for in this Lease, and upon performing and observing
all of the terms, covenants, conditions and provisions of this Lease on Tenant's
part to be kept,  observed and performed,  shall quietly hold,  occupy and enjoy
the Leased Premises during the Term without  hindrance,  ejection or molestation
by Landlord or any party lawfully claiming through or under Landlord, subject to
the terms of this Lease.

     17.  Landlord's Right of Access.
          --------------------------

          Landlord  may,  SUBJECT  TO  GOVERNMENTAL   AND  TENANT'S   REASONABLE
REQUIREMENTS WITH RESPECT TO CONFIDENTIALITY AND SECURITY, during any reasonable
time or times AND UPON  TWENTY-FOUR  (24) HOURS PRIOR NOTICE TO TENANT (unless a
suspected  emergency),  before and after the Lease Commencement Date, enter upon
the Leased  Premises,  any portion  thereof and any  appurtenance  thereto (with
laborers and  materials,  if required)  for the purpose of: (i)  inspecting  the
same;  (ii) making such repairs,  replacements  or  alterations  which it may be
required  to  perform  under the  provisions  of this Lease or which it may deem
desirable for the Leased Premises or the Building,  including but not limited to
repairs and  improvements to space above,  below and/or on the same floor as the
Leased  Premises;  and (iii) DURING THE LAST NINE (9) MONTHS OF THE TERM OF THIS
LEASE,  showing  the Leased  Premises  to  prospective  purchasers  or  tenants.
Landlord  agrees to give  reasonable  notice prior to any such entry except that
Landlord  may enter  without  notice in the case of a  suspected  emergency.  In
making  such an  entry,  Landlord  agrees  to use  reasonable  efforts  to avoid
interfering  with the regular and usual  conduct of the  Tenant's  business.  If
Tenant shall carpet over the floor of the Leased  Premises,  Landlord shall have
the  right to cut such  carpeting  in order  to make or  install  any  necessary
electrical  or  telephone  equipment  or wiring to  service  other  parts of the
Building,  without being held liable therefor,  provided Landlord shall have the
carpeting  restored  in  a  workmanlike   manner  and  to  Tenant's   reasonable
satisfaction.

OR  SPECIFIC  PERFORMANCE.

          (b) Force  Majeure.  LANDLORD'S  AND  TENANT'S  TIME TO PERFORM  THEIR

     19.  Hazardous Material.
          ------------------

          For purposes of this Lease,  the term  "Hazardous  Material" means any
hazardous  substance,  hazardous  waste,  infectious  waste, or toxic substance,
material,  or waste which becomes  regulated or is defined as such by any local,
state or federal governmental authority.  Landlord covenants that, to its actual
knowledge,  there is no Hazardous  Material located in, on or under the Building
as of the date of this Lease in violation of any federal or state law.  Landlord
hereby agrees to indemnify Tenant from and against any claims,  damages,  losses
or liabilities  (including  reasonable  attorney's  fees) incurred by Tenant and

indemnify  Landlord  from and  against  any breach by Tenant of the  obligations
stated  in the  preceding  sentence,  and  agrees to  defend  and hold  Landlord
harmless  from and against any and all claims,  judgments,  damages,  penalties,
fines, costs, liabilities, or losses (including, without limitation,  diminution
in value of the Building, damages for the loss or restriction or use of rentable
space or of any amenity of the Building, damages arising from any adverse impact
on  marketing  of space in the  Building,  sums paid in  settlement  of  claims,

                                       28
<PAGE>
Landlord  by  Tenant  includes, without limitation, costs incurred in connection
with  any investigation of site conditions and any cleanup, remedial removal, or
restoration  work  required  due  to the presence of Hazardous Material.  Tenant
shall  promptly  notify  Landlord  of any release of a Hazardous Material in the
Leased Premises or at the Building of which Tenant becomes aware, whether caused
by  Tenant  or  any  other  person or entity.  The provisions of this Section 19
shall  survive  the  termination  of  the  Lease.

          (a) Definition and Consent. The term "Hazardous  Substance" as used in
              ----------------------
this Lease shall mean any product, substance,  chemical, material or waste whose
presence,  nature,  quantity and/or  intensity of existence,  use,  manufacture,

environment  or  the  Leased  Premises,   (b)  regulated  or  monitored  by  any
governmental  entity,  (c) a basis for liability of Landlord to any governmental
entity or third party under any  federal,  state or local  statute or common law
theory or (d) defined as a hazardous material or substance by any federal, state
or local law or  regulation.  Except for small  quantities  of  ordinary  office
supplies such as copier  toner,  liquid paper,  glue,  ink and common  household
cleaning materials,  Tenant shall not cause or permit any Hazardous Substance to
be brought,  kept,  or used in or about the Leased  Premises or the  Building by
Tenant, its agents, employees, contractors or invitees.

          (b) Duty to Inform Landlord.  If Tenant knows, or has reasonable cause
              -----------------------
to believe,  that a Hazardous  Substance,  or a condition involving or resulting
from same,  has come to be located in, on or under or about the Leased  Premises
or the Building,  Tenant shall  immediately  give written notice of such fact to
Landlord.  Tenant  shall  also  immediately  give  Landlord  (without  demand by
Landlord) a copy of any statement,  report, notice,  registration,  application,
permit,  license,  given to or received  from,  any  governmental  authority  or
private party, or persons entering or occupying the Leased Premises,  concerning
the  presence,  spill,  release,  discharge  of or  exposure  to, any  Hazardous
Substance or contamination in, on or about the Leased Premises or the Building.

          (c) Inspection; Compliance. Landlord and Landlord's employees, agents,
              ----------------------
contractors and lenders shall have the right to enter the Leased Premises at any
time in the  case of an  emergency,  and  otherwise  at  reasonable  times  upon
reasonable  advance  notice,  for the purpose of inspecting the condition of the
Leased  Premises and for  verifying  compliance  by Tenant with this Section 19.
Landlord shall have the right to employ experts and/or consultants in connection
with  its   examination  of  the  Leased   Premises  and  with  respect  to  the
installation,  operation,  use,  monitoring,  maintenance,  or  removal  of  any
Hazardous  Substance on or from the Leased  Premises.  The costs and expenses of
any  such  inspections  shall be paid by the  party  requesting  same,  unless a
contamination,  caused or materially contributed to by Tenant, is found to exist
or be imminent, or unless the inspection is requested or ordered by governmental
authority  as  the  result  of  any  such  existing  or  imminent  violation  or
contamination.  In any such  case,  Tenant  shall  upon  THIRTY  (30) DAYS PRIOR
WRITTEN NOTICE, WHICH NOTICE SHALL INCLUDE SUPPORTING DOCUMENTATION FOR THE COST
OF  SUCH  REPAIRS,  reimburse  Landlord  for  the  cost  and  expenses  of  such
inspection.

     20.  Certificates.
          ------------

          Tenant shall,  without charge  therefor,  at any time and from time to
time,  within  twenty (20) days after  request  therefor by  Landlord,  execute,
acknowledge and deliver to Landlord a written estoppel certificate certifying to
Landlord,  any  mortgagee,  assignee of a  mortgagee,  or any  purchaser  of the
Building,  or any other person  designated  by Landlord,  as of the date of such
estoppel  certificate,  (i) that Tenant is in possession of the Leased  Premises
(if  accurate),  (ii) that this Lease is unmodified and in full force and effect
(or if there have been modifications, that the Lease is in full force and effect
as modified and setting forth such  modification);  (iii) whether or not, to the
best of Tenant's  knowledge,  there are then  existing  any set-offs or defenses
against  the  enforcement  of any right or remedy  of  Landlord,  or any duty or
obligation of Tenant hereunder (and, if so, specifying the same in detail); (iv)
the dates through which Basic Rent and  Additional  Charges have been paid;  (v)
that  Tenant  has no  knowledge  of any  then  uncured  defaults  on the part of
Landlord under this


                                       29
<PAGE>
Lease  (or  if Tenant has knowledge of any such uncured defaults, specifying the
same in detail); (vi) that Tenant  has no knowledge of any event having occurred
that  authorizes  the termination of this Lease by Tenant (or if Tenant has such
knowledge,  specifying  the  same  in  detail); (vii) the amount of any Security
Deposit  held by Landlord; (viii) other matters reasonably requested by Landlord
and  (ix)  such  other matters as to material facts as Tenant deems necessary to
make  the  certificate  accurate.  Tenant  shall  be in material default of this
Lease  if  Tenant  shall  fail to so execute and deliver such a written estoppel
certificate.

     21.  Surrender of Leased Premises.
          ----------------------------

          Tenant  shall,  on or before the last day of the Term, or upon earlier
termination  hereof  or of  Tenant's  right to occupy  the  Leased  Premises  in
accordance with the terms hereof, (i) peaceably and quietly leave, surrender and
yield up to Landlord the Leased Premises, free of subtenancies, broom clean and,
subject to the  provisions  of Section  13 hereof,  in good order and  condition
except for  reasonable  wear and tear AND DAMAGE  DUE TO  CASUALTY  OR THE GROSS
NEGLIGENCE  OR  WILLFUL   MISCONDUCT  OF  LANDLORD  (OR  LANDLORD'S   EMPLOYEES,
CONTRACTORS,  OR  AGENTS),  and (ii) at its  expense,  remove  from  the  Leased
Premises all movable trade fixtures,  furniture,  equipment,  and other personal
property,  provided that Tenant shall promptly  repair any damage caused by such
removal.  Any of such  property not so removed may, at  Landlord's  election and
without limiting Landlord's right to compel removal thereof, be deemed abandoned
and either may be  retained by  Landlord  as its  property  or be  disposed  of,
without  accountability,  in such  manner  as  Landlord  may see fit.  EXCEPT AS
OTHERWISE  LISTED ON  EXHIBIT G  ATTACHED  HERETO,  ALL  affixed  installations,
alterations, additions, betterments and improvements to the Leased Premises made
by either  Landlord  or  Tenant,  whether at  Landlord's  or  Tenant's  expense,
including,   without  limitation,  all  wiring,  paneling,   partitions,   floor
coverings,  lighting fixtures, built-in cabinets,  bookshelves affixed to walls,
and the like,  unless  designated  in writing by  agreement  of the parties upon
installation,  shall become the property of Landlord  when  installed  and shall
remain with the Leased  Premises at the expiration or sooner  termination of the
Term, except that Landlord shall have the right, by notice to Tenant at the time
of approving  Tenant's plans for such  improvements,  to require Tenant,  at its
expense,  to remove any of such property  installed by or at the sole expense of
Tenant or other remaining  property  objectionable to Landlord and to repair any
damage caused by such removal. In the event Tenant fails to perform such removal
and repair,  as  aforesaid,  Landlord may remove any property of Tenant from the
Leased  Premises and store the same elsewhere at the expense and risk of Tenant.
The  provisions of this Section shall survive any  expiration or  termination of
this Lease.

     22.  Alterations and Additions.
          -------------------------

          (a)  Tenant  will not make or permit  anyone to make any  alterations,
additions or improvements, structural or otherwise ("Alterations"), in or to the
Leased Premises or the Building,  without first obtaining the written consent of
Landlord which consent may be granted or withheld by Landlord as provided below.
Alterations  shall  include,  but shall not be limited to, the  installation  or
alteration  of  security  or fire  protection  systems,  communication  systems,
millwork,  shelving, file retrieval or storage systems, carpeting or other floor
covering,  window and wall coverings,  electrical distribution systems, lighting
fixtures,  telephone  or  computer  system  wiring,  HVAC and  plumbing.  At the
expiration  of the Term,  Landlord  may require  the removal of any  Alterations
installed by Tenant which Landlord has identified at the time Landlord  approves
the plans  therefore and the restoration of the Leased Premises and the Building
to their prior condition, at Tenant's expense. If, as a result of any Alteration
made by  Tenant,  Landlord  is  obligated  to  comply  with the  Americans  With
Disabilities  Act or any other law or regulation  and such  compliance  requires
Landlord to make any  improvement  or Alteration to any portion of the Building,
as a condition to Landlord's  consent,  Landlord shall have the right to require
Tenant to pay to Landlord prior to the construction of any Alteration by Tenant,
the entire  cost of any  improvement  or  Alteration  Landlord is  obligated  to
complete by such law or regulation.  Should  Landlord  permit Tenant to make its
own  Alterations,  Tenant shall use only such  contractor as has been  expressly
approved by Landlord, and Landlord may require Tenant to provide to Landlord, at
Tenant's sole cost and expense, a lien and completion bond in an amount equal to
ONE HUNDRED  TWENTY-FIVE  PERCENT (125%) the estimated cost of such Alterations,
to insure Landlord against any liability for mechanic's and materialmen's  liens
and to insure  completion of the work.  Landlord may withhold its consent in its
sole and absolute discretion with respect to any Alterations which are visible


                                       30
<PAGE>
from  the  outside  of  the  Leased  Premises or adversely effect the structural
integrity  of  the  Building or any of the Main Building Systems, as hereinafter
defined.  Landlord  will  not  unreasonably  withhold,  condition  or  delay its
consent  to  any  Alterations  provided  that Tenant otherwise complies with the
provisions  of  this  Section  22 and that the same (i) are not visible from the
outside of the Leased Premises,  and (ii) do not adversely effect the structural
integrity  of  the Building or any of the Building systems which are not located
within  the Leased Premises and which provide services to other occupants of the
Building  in  addition to Tenant, including the structural, electrical, plumbing
and  HVAC  systems ("Main Building Systems").  In the event Landlord consents to
any  such  Alterations, the same shall be performed in accordance with plans and
specifications  reasonably approved in writing by Landlord, which approval shall
not  be  deemed to assure compliance with Laws.  WITH RESPECT TO ALTERATIONS FOR
WHICH  LANDLORD'S CONSENT IS REQUIRED , Tenant shall pay to Landlord a fee equal
to  ten  percent (10%) of the cost of the Alterations to compensate Landlord for
the  overhead  and  other  costs  it  incurs  in  reviewing  the  plans  for the
Alterations  and  in  monitoring  the  construction  of the Alterations and five
percent  (5%) for profit.  In the event Landlord grants such consent and permits
Tenant  to  contract  out  such  work,  which  permission  Landlord  will  not
unreasonably withhold condition or delay, such Alterations shall be performed by
adequately  insured  contractors reasonably approved by Landlord (or in the case
of  an  Alteration  to  the  Main  Building  Systems  approved  by Landlord, the
contractor  designated  by  Landlord (provided such contractor agrees to perform
such  Alterations  at  a  commercially  competitive  cost))  and  in  a good and
workmanlike  manner  in accordance with all applicable Laws with which Tenant is
required to comply pursuant to the terms of this Lease and Requirements of which
Tenant  has  prior  written  knowledge.  Landlord  may  inspect  such  work,  in
progress.  In  any event, Tenant shall indemnify and hold harmless Landlord from
and against any and all reasonable costs, expenses, claims, liens and damages to
person  or  property  resulting from the making of any such Alterations in or to
the  Leased  Premises  or  the Building by Tenant. In the event Tenant makes any
Alterations, Tenant agrees to obtain or cause its contractor to obtain, prior to
the  commencement  of  any  work,  "builders  all  risk"  insurance in an amount
approved  by  Landlord  and  workers compensation insurance.  Except as provided
below,  if  any  Alterations  are  made  without  the  prior  written consent of
Landlord,  Landlord  may  correct  or remove the same UPON NOTICE TO TENANT, WHO
SHALL HAVE A REASONABLE OPPORTUNITY TO MITIGATE ANY DAMAGES, and Tenant shall be
liable  for any and all costs and expenses incurred by Landlord in such removal.
Tenant  shall have the right to make cosmetic, non-structural Alterations to the
Leased  Premises  without  obtaining  Landlord's  prior  written  consent,  but
otherwise  in  accordance  with the provisions of this Section 22, provided that
Tenant  provides  Landlord  with  written  notice  of its intention to make such
Alterations  together  with  the  plans  and  specifications  for the same.  For
purposes  of  this  Section  22  "cosmetic, non-structural Alterations" shall be
deemed  to  mean paint, carpet and wallcovering.  For purposes of the Lease, its
shall  be  deemed  reasonable  for  Landlord  to  require  Tenant to perform any
Alterations  during  non-business  hours  if  such  Alterations  will  create
unreasonable  noise,  noxious  fumes  or  otherwise  interfere  with  the  quiet
enjoyment  of  the  other  tenants in the Building.  In addition, Landlord shall
have  the  right  to  reasonably  approve  the  vendor  who  shall  perform said
Alterations.  To  the extent the Landlord's consent is required pursuant to this
Section  22,  at the written request of Tenant, Landlord agrees to notify Tenant
concurrently  with  Landlord's  consent of any such Alterations whether Landlord
will  require  Tenant to remove such Alterations at the end of the Lease Term if
such  Alterations  are  required  to  be  removed  in accordance with Section 21
hereof.

          (b) Any  Alterations in or about the Leased Premises that Tenant shall
desire to make shall be  presented to Landlord in written  form,  with plans and
specifications  which are sufficiently  detailed to obtain a building permit, if
required.  If Landlord  consents to an  Alteration,  the consent shall be deemed
conditioned  upon Tenant  acquiring  a building  permit (if  required)  from the
applicable governmental agencies, furnishing a copy thereof to Landlord prior to
the  commencement  of the work,  and compliance by Tenant with all conditions of
said permit in a prompt and expeditious  manner.  Tenant shall provide  Landlord
with as-built plans and  specifications  for any Alterations  made to the Leased
Premises.

          (c) Tenant  shall  pay,  when due,  all claims for labor or  materials
furnished  or alleged to have been  furnished  to or for Tenant at or for use in
the Leased  Premises,  which claims are or may be secured by any  mechanic's  or
materialmen's lien against the Leased Premises or the Building,  or any interest
therein. If


                                       31
<PAGE>
Tenant shall, in good faith, contest the validity of any such lien, Tenant shall
furnish to Landlord a surety bond satisfactory to Landlord in an amount equal to
not  less  than  ONE  HUNDRED  TWENTY-FIVE PERCENT (125%) OF  the amount of such
contested  lien  or claim indemnifying Landlord against liability arising out of
such  lien  or  claim.  Such bond shall be sufficient in form and amount to free
the  Building  from  the effect of such lien.  In addition, Landlord may require
Tenant to pay Landlord's reasonable attorneys' fees and costs in connection with
defending  any  such  claims.

          (d) Tenant shall give  Landlord  not less than ten (10) days'  advance
written notice prior to the  commencement  of any work in the Leased Premises by
Tenant, and Landlord shall have the right to post notices of  non-responsibility
in or on the Leased Premises or the Building.

          (e) All Alterations (whether or not such Alterations  constitute trade
fixtures of Tenant) which may be made to the Leased  Premises by Tenant shall be
paid for by Tenant,  at Tenant's sole  expense,  and shall be made and done in a
good and workmanlike manner and with new materials  satisfactory to Landlord and
such  Alterations  shall be the  property  of  Landlord  and remain  upon and be
surrendered with the Leased Premises at the expiration of the Term of the Lease.
Provided no Event of Default exists,  Tenant's  personal property and equipment,
other than that which is  affixed  to the Leased  Premises  so that it cannot be
removed without  material  damage to the Leased Premises or the Building,  shall
remain  the  property  of Tenant  and may be  removed  by Tenant  subject to the
provisions of Section 21 above.

     23.  Holding Over.
          ------------

          If Tenant  remains in  possession  of the Leased  Premises or any part
thereof  after the  expiration  or earlier  termination  of the term hereof with
Landlord's  consent,  such occupancy shall be a tenancy from month to month upon
all the terms and  conditions  of this Lease  pertaining to the  obligations  of
Tenant,  except  that the Basic  Rent  payable  shall be the  greater of (a) one
hundred fifty percent (150%) of the Basic Rent payable immediately preceding the
termination date of this Lease or (b) one hundred  twenty-five percent (125%) of
the fair  market base rent for the Leased  Premises as of the date Tenant  holds
over, and all Options,  if any, shall be deemed  terminated and be of no further
effect.  If Tenant  remains in  possession  of the Leased  Premises  or any part
thereof after the  expiration  of the Term hereof  without  Landlord's  consent,
Tenant shall,  at Landlord's  option,  be treated as a tenant at sufferance or a
trespasser. Nothing contained herein shall be construed to constitute Landlord's
consent to Tenant holding over at the  expiration or earlier  termination of the
Term. Tenant hereby agrees to indemnify,  hold harmless and defend Landlord from
any cost,  loss,  claim or  liability  (including  reasonable  attorneys'  fees)
Landlord may incur as a result of Tenant's  failure to surrender  possession  of
the Leased Premises to Landlord upon the termination of this Lease.

     24.  Signs.
          -----

          Tenant shall not  inscribe,  paint,  affix,  or otherwise  display any
sign,  advertisement  or  notice  on any part of the  outside  or  inside of the
Building without Landlord's consent. Landlord shall provide at no cost to Tenant
a standard suite  identification  sign to be affixed by Landlord at the exterior
entrance to the Leased  Premises in the standard size,  color and style selected
by Landlord for the Building. Landlord shall also prepare and install at no cost
to Tenant a reasonable  quantity of standard name plates as designated by Tenant
on written notice to Landlord for the lobby  directory of the Building,  but not
more than one (1) plate per Two Thousand Five Hundred (2,500) square feet of the
Leased  Premises.  If any other signs  advertisements  or notices  are  painted,
affixed, or otherwise displayed without the prior approval of Landlord, Landlord
shall have the right to remove the same UPON TWENTY-FOUR (24) HOURS PRIOR NOTICE
TO TENANT WHO SHALL HAVE A REASONABLE  OPPORTUNITY TO MITIGATE ANY DAMAGES,  and
Tenant shall be liable for any and all costs and  expenses  incurred by Landlord
in such removal.

     25.  Options.
          -------

          (a)  Definition.  As used in this  Lease,  the word  "Option"  has the
               ----------
following  meaning:  (1) the right or option to extend the Term of this Lease or
to renew this Lease, and (2) the option or right of first refusal to lease the


                                       32
<PAGE>
Leased  Premises or the right of first offer to lease the Leased Premises or the
right  of first refusal to lease other space within the Building or the right of
first  offer  to  lease  other  space  within the Building, and (3) the right or
option  to  terminate  this  Lease prior to its expiration date or to reduce the
size  of  the Leased Premises.  Any Option granted to Tenant by Landlord must be
evidenced  by  a  written  option agreement attached to this Lease as a rider or
addendum  or  said  option  shall  be  of  no  force  or  effect.

          (b) Options Personal.  Each Option granted to Tenant in this Lease, if
              ----------------
any, is personal  to the  original  Tenant and any  Permitted  Transferee  under
Section  10(i) above and may be exercised  only by the  original  Tenant and any
Permitted Transferee while occupying not less than seventy-five percent (75%) of
the entire Leased Premises and may not be exercised or be assigned,  voluntarily
or  involuntarily,  by or to any  person or  entity  other  than  Tenant or such
Permitted  Transferee.  The Options,  if any,  herein  granted to Tenant are not
assignable  separate and apart from this Lease,  nor may any Option be separated
from this Lease in any manner,  either by  reservation  or otherwise.  If at any
time an Option is  exercisable  by  Tenant,  the Lease has been  assigned,  or a
sublease  exists as to any portion of the Leased  Premises,  the Option shall be
deemed null and void and neither Tenant nor any assignee or subtenant shall have
the right to exercise the Option.

          (c) Multiple Options. In the event that Tenant has multiple Options to
              ----------------
extend or renew this Lease a later Option  cannot be exercised  unless the prior
Option to extend or renew this Lease has been so exercised.

          (d)  Effect of  Default  on  Options.  Tenant  shall  have no right to
               -------------------------------
exercise an Option during the time that an Event of Default  exists.  The period
of time  within  which an  Option  may be  exercised  shall not be  extended  or
enlarged by reason of Tenant's  inability  to exercise an Option  because of the
provisions of this Section 25(d).

          (e) Notice of  Exercise  of Option.  Notwithstanding  anything  to the
              ------------------------------
contrary  contained  in Section  27(f),  Tenant may only  exercise  an option by
delivering its written notice of exercise to Landlord by certified mail,  return
receipt and date of delivery requested. It shall be Tenant's obligation to prove
that such notice was so sent in a timely manner and was delivered to Landlord by
the U.S. Postal Service.

     26.  Leasing Commission.
          ------------------

          Tenant  represents  and warrants  that,  except for  Tenant's  Leasing

Lease.  Tenant shall  indemnify and hold harmless  Landlord from and against any
other claim or claims for brokerage or other fees or commissions arising from or
out of any breach of the foregoing  representation and warranty.  LANDLORD SHALL
BE RESPONSIBLE  FOR PAYMENT OF THE BROKERS' FEES TO TENANT'S  LEASING BROKER AND
LANDLORD'S  LEASING BROKER PURSUANT TO SEPARATE  AGREEMENTS BETWEEN LANDLORD AND
SUCH PARTIES.

     27.  General Provisions.
          ------------------

          (a) Binding Effect. The covenants,  conditions,  agreements, terms and
              --------------
provisions of this Lease shall be binding upon and shall inure to the benefit of
the parties hereof and, subject to the provisions of Section 10 hereof,  each of
their respective personal representatives, successors and assigns.

          (b) Laws.  It is the  intention of the parties  hereto that this Lease
              ----
(and the terms  and  provisions  hereof)  shall be  construed  and  enforced  in
accordance with the laws of the jurisdiction in which the Building is located.

          (c) Attorneys' Fees. If Landlord or Tenant brings an action to enforce
              ---------------
the terms hereof or declare rights  hereunder,  the prevailing party in any such
action, or appeal thereon,  shall be entitled to its reasonable  attorneys' fees
and court costs to be paid by the losing party as fixed by the court in the same
or  separate  suit,  and  whether or not such  action is pursued to  decision or
judgment.  The attorneys' fee award shall not be computed in accordance with any
court fee schedule,  but shall be such as to fully reimburse all attorneys' fees
and court costs reasonably incurred in good faith. Landlord shall be entitled to


                                       33
<PAGE>
reasonable  attorneys'  fees  and  all  other costs and expenses incurred in the
preparation  and  service  of notices of default and consultations in connection
therewith, whether or not a legal action is subsequently commenced in connection
with such default.  Landlord and Tenant agree that attorneys' fees incurred with
respect  to  defaults  and  bankruptcy  are  actual  pecuniary losses within the
meaning of Section 365(b)(1)(B) of the Bankruptcy Code or any successor statute.

          (d) Waiver. No failure by Landlord OR TENANT to insist upon the strict
              ------
performance of any term, covenant, agreement, provision, condition or limitation
of this  Lease or to  exercise  any  right or  remedy  consequent  upon a breach
thereof,  and no  acceptance  by the Landlord of full or partial rent during the
continuance of any such breach,  shall constitute a waiver of any such breach or
of any such term, covenant,  agreement,  provision,  condition or limitation. No
term, covenant, agreement,  provision,  condition or limitation of this Lease to
be kept,  observed or performed by Landlord or by Tenant, and no breach thereof,
shall be waived,  altered or modified except by a written instrument executed by
Landlord or by Tenant,  as the case may be. No waiver of any breach shall affect
or alter this Lease, but each and every term,  covenant,  agreement,  provision,
condition and  limitation of this Lease shall  continue in full force and effect
with respect to any other existing or subsequent  breach thereof.  No failure by
Landlord to insist upon the strict performance of any term, covenant, agreement,
provision,  condition  or  limitation  of a lease  with any  other  tenant or to
exercise any right or remedy consequent thereof shall constitute a waiver of any
similar term, covenant, agreement,  provision, condition or limitation contained
in this Lease unless the same be incorporated in a written  instrument signed by
Landlord  and  making  specific  reference  to this  Lease  and to the  Tenant's
obligations hereunder.

          (e)  Security   Interest.   In  consideration  of  the  covenants  and
               -------------------
agreements  contained  herein,  and as a material  consideration to Landlord for
entering  into this Lease,  Tenant hereby  unconditionally  grants to Landlord a
continuing  security interest in and to all personal property owned (not leased)
by Tenant and located or left at the Leased  Premises and the Security  Deposit,
if any,  and any advance  rent  payment or other  deposit,  now in or  hereafter
delivered to or coming into the possession,  custody or control of Landlord,  by
or for the account of Tenant,  together with any increase in profits or proceeds
from such property.  The security interest granted to Landlord hereunder secures
payment and  performance  of all  obligations  of Tenant under this Lease now or
hereafter  arising  or  existing,  whether  direct  or  indirect,   absolute  or
contingent,  or due or to become due. In the event of a default under this Lease
which is not cured within the applicable grace period,  if any,  Landlord is and
shall be entitled to all the rights, powers and remedies granted a secured party
under  the  Commonwealth  of  Virginia  Uniform  Commercial  Code and  otherwise
available  at law or in  equity,  including,  but not  limited  to, the right to
retain as damages the personal  property,  Security Deposit and other funds held
by  Landlord,  without  additional  notice or  demand  regarding  this  security
interest. Tenant agrees that it will execute such other documents or instruments
as may be reasonably necessary to carry out and effectuate the purpose and terms
of this Section,  or as otherwise  reasonably  requested by Landlord,  including
without limitation,  execution of a UCC-1 financing statement.  Tenant's failure
to execute such  documents  within ten (10) business  days after written  demand
shall  constitute a material default by Tenant  hereunder.  Tenant hereby waives
any rights it may have under the  Commonwealth  of Virginia  Uniform  Commercial
Code  which  are  inconsistent   with  Landlord's  rights  under  this  Section.
Landlord's  rights under this Section are in addition to Landlord's rights under
Sections 11 and 14.  NOTWITHSTANDING  ANYTHING TO THE CONTRARY CONTAINED IN THIS
SECTION  27(E),  THE SECURITY  INTEREST  GRANTED BY TENANT TO LANDLORD  SHALL BE
SUBORDINATE TO THE SECURITY INTEREST, IF ANY, GRANTED TO TENANT'S LENDERS IN THE
ORDINARY  COURSE OF TENANT'S  BUSINESS.  AT TENANT'S  REQUEST,  LANDLORD  SHALL,
WITHIN TEN (10) DAYS OF RECEIPT OF ANY SUCH LIEN WAIVER FROM  TENANT,  EXECUTE A
LIEN WAIVER,  THE FORM OF WHICH SHALL BE  REASONABLY  SATISFACTORY  TO LANDLORD,
WAIVING  LANDLORD'S  SECURITY  INTEREST IN THE COLLATERAL  DESCRIBED IN ANY SUCH

expressly  consented  to  by Landlord, and (c) no waiver of a rule or regulation
granted  to  any  tenant  shall  relieve any other tenant from the obligation of
complying  with  the  rule or regulation unless such other tenant has received a

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
non-enforcement  with  respect to any tenant  shall  constitute  a waiver of the

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 such tenant's Lease was entered into

set  forth  below.

     1.     Tenant  and  Lender  agree  that  until the Mortgage is satisfied of
record:

          (a)     The  Lease  and all of Tenant's rights under the Lease are and
will  remain  subject and subordinate to the Mortgage and to all future advances
made  under  the Mortgage and to any other mortgage or other security instrument

subordinate  the  Lease  to any other lien against the Property without Lender's
prior  consent;

          (b)     Except for any security deposit, Tenant will not pay Rent more
than  one  month  in  advance  and  will  not  offset  against  Rent;

          (c)     Upon  receipt  of notice from Lender, Tenant will pay the rent
as  and  when  due  under  the Lease to Lender and the payments will be credited
against  the  Rent  due  under  the  Lease;  and

consent,  except  as  follows:

          (a)     Except as permitted in the Mortgage or Assignment, Tenant will
not  enter  into any amendment that reduces the Rent due under the Lease without
Lender's  prior  consent  which will not be unreasonably withheld, except Tenant
may  agree to a rent reduction without Lender's prior consent in connection with
an  extension  or renewal of the Lease but only if the rent for the extension or
renewal  period  is consistent with then prevailing market terms for like space;

          (b)     Except as permitted in the Mortgage or Assignment, Tenant will
not  amend the Lease to reduce the initial term of the Lease or any renewal term
of  the Lease after the renewal has been exercised, will not terminate or cancel

months  of the initial or any renewal term of the Lease, Tenant may terminate or
cancel  the  Lease or surrender the Leased Space without Lender's prior consent;

     3.     If  Tenant  is  not  in  default  under this Agreement and is not in
default beyond any applicable grace and cure periods under the Lease, Tenant and
Lender  agree  as  follows:

          (a)     If  Lender commences a judicial or non-judicial foreclosure or
other  proceeding  to  enforce  the  Mortgage or exercises any power of sale (an
"Action"),  Lender  will not name Tenant as a party to the Action unless joinder
 ------
is  required  under  applicable  law  and  in  such  case  Lender  will not seek
affirmative  relief  from  Tenant, the Lease will not be terminated and Tenant's
possession  will  not  be  disturbed;

          (b)     If  Lender  or  any  other  entity  (a  "Successor  Landlord")
acquires  the  Property  through an Action or by deed-in-lieu of foreclosure (an
"Acquisition"),  Successor  Landlord will not disturb Tenant's possession of the
 -----------
Leased  Space,  the  Lease will continue in full force and effect with Successor
Landlord  and  Tenant  bound  by  the  Lease;  and

          (c)     If,  notwithstanding the foregoing, the Lease is terminated as
a  result  of  an  Action, a lease between Successor Landlord and Tenant will be
deeded  created  on  the  same  terms  as  the Lease except that the term of the
replacement  lease  will  be  the  then  unexpired term of the Lease.  Successor
Landlord  and  Tenant  will  execute  a  replacement  lease on such terms as the
request  of  either.

     4.     Upon  an  Acquisition  Tenant will recognize and attorn to Successor
Landlord  as the landlord under the Lease for the balance of the term.  Tenant's
attornment  will  be  self-operative  with  no  further  instrument  required to
effectuate  the  attornment  except that at Successor Landlord's request, Tenant
will  execute  instruments  reasonably  satisfactory  to  Successor  Landlord
confirming  the  attornment.

     5.     Successor  Landlord  will  not  be:

          (i)  liable for any act or omission of Landlord occurring prior to the
               date of Acquisition except for repair and maintenance obligations
               of a continuing nature imposed on the landlord under the Lease:

          (ii) required  to credit  Tenant  with any Rent for any rental  period
               beyond the then current rental period or for any security deposit
               unless it has been received by Successor Landlord;

          (iii)bound by any  amendment,  renewal or  extension of the Lease that
               is not in writing  signed by both  Tenant and  Landlord,  that is
               inconsistent  with the terms of this  Agreement  or that was made
               without  Lender's  prior  consent,  if Lender's prior consent was
               required under the terms of this Agreement;

          (iv) subject  to  any  credits,  offsets,  claims,   counterclaims  or
               defenses that Tenant may have against  Landlord  arising prior to
               the date of Acquisitions;

          (v)  liable  for any  damages  Tenant  may  suffer  as a result of any
               misrepresentation, breach of warranty or any act of or failure to
               act by any party other than Successor Landlord;

          (vi) obligated  to make any payment or to give any credit or allowance
               to Tenant including,  without  limitation,  for any improvements,
               demolition  or other  work in the  Leased  Space or the  Property
               (other than to reconstruct  after a casualty or  condemnation  if
               the  insurance  or  condemnation  proceeds  are paid to Successor
               Landlord)   or  to   undertake   or  complete   construction   of
               improvements  in the Leased  Space or the  Property or to pay any
               leasing commissions arising out of the Lease; or


                                      F-5
<PAGE>
          (vii)liable for any  obligations  of Landlord with respect to off-site
               property or  facilities  for the use of Tenant  (such as off-site
               leased  space or  parking)  unless  Successor  Landlord  succeeds
               through Acquisition to Landlord's right, title or interest in the
               off-site property.

     6.     Lender  will  have  the  right,  but not the obligation, to cure any
default  by  Borrower under the Lease.  Tenant will notify Lender of any default
by  Borrower  that would entitle Tenant to terminate the Lease or abate the Rent
and  any  notice of termination or abatement will not be effective unless Tenant
has  so notified Lender of the default and Lender has had a thirty (30) day cure
period  (or  such  longer  period  as  may  be  necessary  if the default is not
susceptible to cure within thirty (30) days commencing on the latest to occur of
the  date  on  which  (i)  the  cure period under the Lease expires; (ii) Lender
receives  the  notice  required  by this paragraph; and (iii) Successor Landlord
obtains  possession  of  the  Property if the default is not susceptible to cure
without  possession.

     7.     Tenant  certifies  that the Lease represents the entire agreement
between  Borrower and Tenant  regarding the Leased  Space;  the Lease is in full
force and  effect;  neither  party is in  default  under the  Lease  beyond  any
applicable  grace and cure  periods  and not event has  occurred  which with the
giving of notice or passage of time would  constitute a default under the Lease;
Tenant has entered into  occupancy  and is open and  conducting  business in the
Leased Space and all  conditions  to be performed to date by Landlord  have been
satisfied.

     8.     Upon  not  less  than  twenty  (20)  days prior request from Lender,
Tenant  will  execute, acknowledge and deliver to Lender an estoppel certificate
containing  the  information  required  by  the  Lease and any other information
reasonably  requested  by  Lender.

     9.     All  notices, requests or consents required or permitted to be given
under  this  Agreement  must  be  in  writing and sent by certified mail, return
receipt  requested  or  by  nationally  recognized  overnight  delivery  service
providing  evidence of the date of delivery, with all charges prepaid, addressed
to  the  appropriate  party  at  its  Notice  Address.

     10.     Tenant  acknowledges  and  agrees  that  this Agreement constitutes
notice  to  Tenant  of  the existence of the Mortgage and that the Lease and the
Rent  have  been  assigned  to  Lender  as  security  for  the  Loan.

     11.     Any  claim by Tenant against Successor Landlord under this Lease or
this  Agreement will be satisfied solely out of Successor Landlord's interest in
the  Property  and  Tenant  will  not  seek recovery against or out of any other
assets  of  Successor  Landlord.  Successor  Landlord  will have no liability or
responsibility  for any obligations under the Lease that arise subsequent to any
transfer  of  the  Property  by  Successor  Landlord.

     12.     This  Agreement  is governed by and will be construed in accordance
with  the  laws  of  the state or commonwealth in which the Property is located.

     13.     Lender and Tenant waive trial by jury in any proceeding brought by,
or  counterclaim  asserted  by,  Lender  or  Tenant  relating to this Agreement.

     14.     If  there  is  a  conflict  between the terms of the Lease and this
Agreement,  the  terms  of  this Agreement will prevail.  If there is a conflict
between  the terms of the Lease and the Mortgage, the terms of the Mortgage will
prevail.

     15.     This Agreement binds and inures to the benefit of Lender and Tenant
and  their  respective  successors,  assigns,  heirs, administrators, executors,
agents  and  representatives.
