IBAH, Inc. - Company Overview
- -----------------------------

       IBAH, Inc. ("IBAH" or the "Company") is a worldwide leader in providing
comprehensive product development services to client companies in the
pharmaceutical, biotechnology, medical device, and diagnostics industries. IBAH
is a clinical research organization ("CRO") which offers services for all stages
of drug development.

       The Company provides its services through two primary operating
divisions, the United States and International Clinical Services Divisions
(together defined as the "Clinical Services Division") and Bio-Pharm
Pharmaceutics Services (the "Pharmaceutics Services Division"). On October 1,
1996, the Company acquired The Hardardt Group ("THG"), a clinical monitoring and
clinical trials management company, integrating it into the Clinical Services
Division. In July, 1996, the Company acquired Resource Biometrics, Inc. ("RBI")
to provide software tools to enhance the Company's and its clients' efficiency
and speed in analyzing clinical data. As of December 31, 1996, the Company had a
worldwide staff of 755 full-time equivalents. In addition, on February 28, 1997,
the Company signed a definitive agreement to purchase Pharmaco Pty., Ltd., one
of the leading CROs in Australia. The closing of this acquisition is contingent
upon the completion of due diligence. Pharmaco Pty., Ltd. had revenues of
approximately $1.2 million in 1996.

       The Company generates almost all of its revenue by providing services on
a contractual basis to its clients. All of the Company's services are designed
to help client companies accelerate products from discovery through development
and commercialization faster and cost-effectively.

       The Clinical Services Division, the core of IBAH, is a full service
       ------------------------------
international CRO that began operations in 1985. This division's primary
services are designing product development programs, managing pre-clinical
studies, design and conduct clinical trials, clinical data management and
biostatistical analysis, writing reports of study findings, health economics
analysis and post-marketing studies, and regulatory dossier filings.

       This division earns its revenues by providing services on a contractual
basis to its clients. The division's worldwide staff is located in offices in
the United States, Australia, Belgium, the Czech Republic, Denmark, France,
Germany, Spain, Switzerland and the United Kingdom. Through a joint venture with
a Russian company, this division also operates an office located in Russia.

       Since the inception of Bio-Pharm Clinical Services, Inc., the predecessor
to IBAH, IBAH has prepared 47 New Drug Applications ("NDA"), five of which were
submitted in 1996, including one of the largest ever filed.

       The Pharmaceutics Services Division provides traditional product
       -----------------------------------
formulation services, process development, manufacture of drugs and placebos for
clinical trials, pilot plant manufacturing, methods development, analytical
testing, and clinical trials drug packaging. The division's services also
include shelf life stability testing, process validation, and analysis of other
chemical and physical properties required in regulatory submissions.

       This division began in October, 1993 and currently operates from a 20,000
square foot Good Manufacturing Practice ("cGMP") manufacturing facility with
full pilot plant capabilities located in suburban Philadelphia. To accommodate
growth, the division recently entered into a lease for a 124,000 square foot
facility in the same area as its current facility. The division expects to phase
in operations in the new facility over the next several years, beginning in the
second quarter of 1997.

Company History
- ---------------

       IBAH was originally Affinity Biotech, Inc., a New Jersey corporation (the
"New Jersey Corporation"), which was incorporated in January, 1990. In April,
1992, the New Jersey Corporation was merged into Affinity Biotech, Inc., a
Delaware corporation ("Affinity"), which was incorporated in February, 1992. In
April, 1992, Affinity completed its initial public offering of common stock.

       On April 27, 1994, Bio-Pharm Clinical Services, Inc. ("Bio-Pharm"), a
clinical research organization, and Affinity, a drug delivery and technology
corporation, merged (the "Merger") and simultaneous with the Merger, Affinity
changed its name to IBAH.

       Bio-Pharm was founded in December, 1985 by Geraldine A. Henwood,
President of Bio-Pharm from 1985 through April, 1994, and President and Chief
Executive Officer of IBAH since April, 1994. Since the Merger resulted in the
former Bio-Pharm shareholders having a majority ownership of IBAH, the Merger
was accounted for as an acquisition of Affinity by Bio-Pharm.

       In 1991, Bio-Pharm opened its first European operation based in
Frankfurt, Germany. Subsequently, an office was opened in Australia in 1993. In
January, 1994, Bio-Pharm purchased European Pharmaceutical Investigation
Consultants Limited ("EPIC"), a CRO headquartered in the United Kingdom with an
office in Switzerland. The EPIC acquisition was a major expansion step allowing
the Company to serve the United Kingdom and strengthen its position throughout
Europe. Since the EPIC acquisition, the Company has opened offices in France,
Belgium, Spain, Denmark, and the Czech Republic. Through a joint venture with a
Russian company, IBAH also operates an office located in Russia.

       On July 28, 1995, the Company sold its Drug Delivery Services Division,
the part of Affinity which offered proprietary drug delivery services, to a
management group from that division.

       On August 11, 1995, IBAH completed a private placement of convertible
preferred stock and warrants for a total investment in the Company of $7
million. The private placement was made to improve working capital and place the
Company in compliance with certain financial requirements necessary for the
continued listing of the stock on the NASDAQ National Market. The registration
with the Securities and Exchange Commission of the resale of the 5,997,324
shares of common stock, issuable upon conversion of the preferred stock and
exercise of the warrants issued in this private placement became effective on
October 31, 1995. See Note 4 of Notes to Consolidated Financial Statements.

       On April 19, 1996, the Company completed a public offering of 3,000,000
shares of common stock of the Company to selected institutional investors,
netting the Company $18 million.

       On July 18, 1996, IBAH acquired RBI based in the San Francisco,
California area. RBI is a provider of software products and data services to the
pharmaceutical, biotechnology, and medical device industries. The software tools
are being designed to increase the efficiency of data clean-up, database
consolidation, data analysis and reporting.

       On October 1, 1996, IBAH acquired THG, located in northern New Jersey.
THG provides clinical trials management and clinical monitoring services to the
pharmaceutical and biotechnology industries, predominantly in the United States.
The THG operation has been completely integrated into the U.S. Clinical Services
Division. The acquisition has added critical mass and management talent to the
Company, enhancing its ability to obtain and perform large clinical trials.

Industry Background and Trends
- ------------------------------

       New pharmaceutical, biotechnology, medical device and diagnostic products
generally must undergo extensive testing to demonstrate their safety and
effectiveness in order to obtain regulatory approval for commercialization.
Companies seeking such approval are responsible for performing and analyzing the
results of

                                       4
<PAGE>
 
multi-phase clinical trials that typically span two to five years and involve
hundreds to thousands of human participants. Historically, clinical trials were
performed almost exclusively by in-house personnel of the companies that owned
the products under development. For over a decade, there has been a growing
trend for companies developing new products to outsource certain activities by
contracting with CROs for the performance of clinical trials and related
activities in the development and approval process.

       IBAH believes, based on its experience and reports from industry
analysts, that the following industry trends have increased and will continue to
increase the market for CRO services:

 .   Pharmaceutical and biotechnology research and development expenditures
    continue to increase. From 1995 to 1996, research and development spending
    for major U.S. pharmaceutical companies and the outsourcing of this spending
    continue to increase. Worldwide research and development expenditures were
    estimated at approximately $30 billion for 1996. Increased emphasis on the
    development of effective treatments for chronic disorders and life
    threatening, acute conditions, such as stroke and infectious diseases, is
    contributing to this trend. Requirements from regulatory agencies to conduct
    longer, more complex trials to demonstrate effectiveness and potential long-
    term effects are also factors in this spending growth.

 .   Cost containment pressures continue to escalate as a result of various
    influences, including efforts by governments and managed care organizations
    to control prices, increased competition from generic drugs, and more
    stringent regulatory requirements. As pharmaceutical companies continue
    experiencing pressure on profit margins and attempt to hasten new product
    introductions worldwide, they are increasingly outsourcing to CROs which
    provide expertise, speed, and global reach.

 .   Maturation of the biotechnology industry has substantially increased the
    number of biotechnology drugs in clinical development. Rather than build the
    infrastructure necessary to handle the clinical development stages, many
    biotechnology companies are choosing to outsource to CROs.

 .   Emphasis on globalization has led pharmaceutical and biotechnology companies
    to pursue product development simultaneously in multiple countries and
    conduct programs which simultaneously satisfy the requirements of multiple
    regulatory agencies. In addition, since 1992 guidelines for the conduct of
    clinical research within Europe require more stringent standards. The
    emphasis on globalization combined with escalating complexity has increased
    manpower and resource requirements for clinical trials, which in turn has
    resulted in an increase in the use of CRO services.

The Drug Development Process
- ----------------------------

       Before a drug may be marketed, it must undergo extensive testing and
regulatory review to determine its safety and effectiveness. The following is a
brief description of the stages of U.S. and worldwide drug development. As a
full service CRO, IBAH offers comprehensive services in every phase of this
process:

       Regulatory Affairs - Full-service CROs, such as IBAH, offer regulatory
       ------------------
affairs services which assist clients with the design of regulatory strategy and
span the development process from formulation development to preclinical and
clinical trials through regulatory filings, e.g., New Drug Applications ("NDA"),
Product License Applications ("PLA"), and EU-multistate (cPMP) or National
filings. CROs also assist in the actual preparation of filing and communications
with the regulatory agencies. These services are critical to every phase of the
development process, and to a timely, successful completion of any product
development project.

       Preclinical Testing - The initial stage in the drug development process
       -------------------
is preclinical research. In this stage, the drug is tested in vitro (test tube)
and in animals, generally over one to three years. Safety studies, including
toxicology, are a major portion of this phase along with metabolism, kinetics,
and clinical pathology.

       Phase I - Phase I trials are conducted in healthy volunteers, typically
       -------
18-20 per study, to develop basic safety data relating to toxicity, metabolism,
absorption and other pharmacological actions. In order to establish

                                       5
<PAGE>
 
safe dosage ranges, single and multiple dose tolerance tests are conducted.
Phase I generally lasts from six months to one year.

       Phase II - Phase II trials are conducted on small numbers of subjects,
       --------
typically 100 to 200 patients who suffer from the drug's targeted disease or
condition. Phase II trials last an average of six months to two years and
provide the first evidence of clinical efficacy (effectiveness) at different
doses, as well as additional safety data. These trials may include dose ranging
studies to establish optimal dosages wherein the drugs are usually tested
against a placebo or a currently marketed drug.

       Phase III - Phase III trials are conducted on a significantly larger
       ---------
patient population, from hundreds to thousands of patients who suffer from the
targeted disease. Conducted at numerous investigational sites including
hospitals and clinics, these trials are designed to establish safety and
efficacy as well as the optimal dosing regimen of the drug under study. During
Phase III, which generally lasts from one to three years, the new drug is
compared with a placebo or with one or more drugs with established safety and
efficacy profiles in the same therapeutic category.

       Phase IV - As a condition of granting marketing approval, the Food and
       --------
Drug Administration ("FDA") or other global regulatory agencies, may require a
sponsor to conduct additional clinical trials or post-approval trials of the
product, monitor long-term risks and benefits, study different dosage levels, or
evaluate different safety and efficacy parameters in target patient populations.
Clients also pursue Phase IV trials to enhance such things as product profiles
with new claims and dosage regimens to gain comparative marketing information or
for health economics and outcomes research. These trials generally last one to
four years.

       Regulatory Application - The regulatory filing which is submitted to a
       ----------------------
regulatory agency, such as the FDA or the Medicine Control Agency ("MCA"), is a
comprehensive filing that averages over 100,000 pages. It includes manufacturing
and animal testing data as well as clinical trial data. The largest portion of
the clinical data contained in a regulatory filing is generated during the Phase
II and III trials.

       Regulatory Reviews - FDA reviews of filings in the U.S. can last from
       ------------------
several months to several years, while European regulatory review generally
lasts 10-18 months in most countries. Regulatory approval is required prior to
commercialization. The FDA has been under increasing scrutiny and pressure to
shorten its approval process and has accelerated this process by granting
expedited approval of lifesaving drugs or drugs for conditions where there is no
current treatment.

       Pharmaceutics Services - In parallel with the phases described above, the
       ----------------------
product dose form development process involves formulation development,
including placebo and active drug clinical manufacturing and process development
for commercial manufacturing, the development of analytical methodology,
execution of a high number of analytical tests, as well as stability testing.
These services are also being outsourced more extensively as companies increase
their efforts to cut costs and time from the development process.

IBAH's Services
- ---------------

       IBAH's services cover all phases of the drug development process,
including formulation development, analytical methodology and stability testing,
preclinical through clinical trials, data management and biostatistical
services, pharmacoeconomic studies, and regulatory filings.

Preclinical Services

       IBAH offers a full range of preclinical testing services through an
alliance with the Laboratory of Pharmacology and Toxicology (LPT), a well-
established, experienced, preclinical organization headquartered in Hamburg,
Germany. This includes toxicology, carcinogenicity, mutagenicity, reproduction,
and pathology studies.

                                       6
<PAGE>
 
Clinical Program Management

       IBAH provides a broad range of services related to the design and
management of clinical programs. These activities include program design
strategy for product development to satisfy the regulatory requirements as well
as commercial objectives. The services are designed to achieve the client's
marketing goals by obtaining regulatory approval with maximum quality,
comprehensive product profile and speed to market at an efficient cost. Prior to
the commencement of clinical studies, IBAH assists clients in developing
specific attributes or design of the program to ensure that key product profile
objectives are incorporated into the program's design.

       Once the clinical program has been designed, implementation of clinical
studies includes establishing study sites and monitoring the conduct of the
studies. IBAH recruits qualified independent investigators to carry out the
trials in compliance with applicable regulations and protocols designed for the
specific trial. Clinical monitoring includes regular visits to clinical trial
sites by IBAH's clinical research associates. The monitoring process focuses
heavily on quality control to assure the accuracy and reliability of the data
collected and compliance with all applicable requirements.

       The Clinical Services Division's international project management team
offers experience in over 35 therapeutic areas and utilizes a Worldwide
Operations Database to track study progress.

Data Management, Analysis and Reporting

       Critical to the success of any clinical trial is the assembly, analysis
and reporting of data collected. IBAH's cross-disciplinary teams -skilled in
data management, biostatistics, computer programming, clinical writing, and
regulatory affairs - utilize current data processing equipment and commercial
and proprietary software that enable the Company to process, analyze and present
vast amounts of data. The field data collected at the study sites is assembled
into a database and verified for accuracy of input. The information collected is
then analyzed and its statistical significance ascertained.

       Considerable effort is directed toward the goal of having error-free data
in regulatory filings, thereby increasing reliability of results and minimizing
delays in the approval process.

       IBAH's expertise is applied to create formats, graphics and presentations
to meet regulatory requirements and other client needs. Experienced writers work
with other members of IBAH's staff to prepare comprehensive interpretive reports
on the test results. Proprietary software programs are designed for the client's
use so that the database can be supplemented, reorganized and accessed by the
client for its own purposes or as requested by the reviewing regulatory agency.
The Company also offers a Windows-based Remote Data Entry system which provides
flexibility, security and efficiency in managing data generated in clinical
studies.

       Preparation of NDAs and comparable foreign regulatory filings is a major
undertaking involving complex analyses and presentation of voluminous amounts of
data. The time required for review by the FDA or comparable foreign agencies
often depends on the manner in which the data is analyzed, organized, and
presented in the application. A well prepared filing increases the likelihood
for achieving a favorable outcome.

       IBAH has the experience and the resources to assist clients in preparing
regulatory filings and in responding to inquiries by the reviewing agency. The
regulatory review process normally involves frequent communication between the
applicant and the reviewing staff which IBAH can facilitate. IBAH believes that
its assistance in the preparation of filings and the completion of the approval
process has resulted on occasion in a significant reduction in the time that
would have been required for the clients to prepare the filing and complete the
review process using only internal staff and facilities.

Regulatory Affairs

       Since Bio-Pharm's inception in 1985, the Company has assisted in the
preparation of 47 NDAs, five of which were submitted in 1996, including one of
the largest ever filed.


                                       7
<PAGE>
 
       IBAH provides regulatory consulting services to clients at all stages of
the product development process, often beginning before the client has made the
initial filing for permission to begin human testing. Consulting engagements
focus on such topics as the development plan, protocol design and overall
strategy to meet regulatory requirements. In consulting engagements, as in many
other types of services, IBAH's personnel work closely with the client's staff
to complement the client's expertise and capabilities.

       Increasingly, clients desire approvals in multiple countries. In such
cases, IBAH provides global regulatory affairs advice concerning the
requirements in each jurisdiction where an application will be made.

       IBAH also consults with clients about manufacturing issues related to
regulatory approvals. The principal focus of such consultation is usually
compliance with regulatory requirements, including good manufacturing practices,
product testing and accountability.

       Clients may enter into multiple contracts at different stages in the
development process. Sometimes IBAH's initial contract in connection with a new
product covers only consulting services. However, successful consulting projects
may lead to contracts for substantial additional services at later stages of the
development process.

Pharmaceutics Services

       A fully equipped cGMP facility, specifically designed to carry out
clinical supplies manufacturing and formulation services, along with an
experienced clinical supply team allows for efficient production of high quality
supplies.

       The Company also provides a full range of formulations services including
formulation development, analytical methods development, validation and testing,
and stability storage and testing.

       Complex logistics are required to package, distribute and account for the
large quantities of study drug supplies used in a clinical trial, especially for
double-blind studies. For example, IBAH often receives bulk quantities of a
study drug and is engaged to render pharmaceutical handling services, or to
label, package and distribute a study drug in individual patient packs,
sometimes in refrigerated form. In addition, the Company also has the capability
to encapsulate solid dosage forms for blinded clinical trials and prepare
matching placebos.

Software Development
- --------------------

       Through RBI, the Company develops and markets software products for use
in clinical development. The software tools are being designed to increase the
efficiency of data, archiving, optical imaging, work flow management as well as
data clean-up, database consolidation, data analysis and reporting.

Clients and Marketing
- ---------------------

       IBAH serves a broad range of clients, including most of the major
multinational pharmaceutical and biotech companies as well as smaller companies
in the pharmaceutical and biotechnology industries. Medical devices and
diagnostics increasingly are becoming subject to FDA approval, and manufacturers
of such products have been a growing part of IBAH's clientele in recent years.
IBAH attempts to develop close ties with its clients and has experienced a high
degree of repeat business after a relationship is established.

       Over the last three years, four of IBAH's clients accounted for 10% or
more of its revenues in any given year. In 1996, one client accounted for 20.4%;
in 1995, two clients accounted for 10.2% and 14.9% respectively; and in 1994,
three clients accounted for 10.4%, 13.1%, and 14.7% respectively. These four
clients are international pharmaceutical companies with annual revenues
exceeding $2 billion.


                                       8
<PAGE>
 
       Historically, IBAH attracted new clients due to its reputation for speed
and quality, recommendations from established clients and the personal efforts
of its executives. Although these sources of attracting business remain. IBAH
also relies on and utilizes business development professionals in the Company's
worldwide locations to obtain new business.

       Marketing efforts also include advertising through direct mail,
professional journals and trade publications; exhibiting at industry meetings;
distributing newsletters to industry professionals; and speaking engagements and
publications by key employees.

Contractual Arrangements
- ------------------------

       Compensation for services is arranged on a combination of fixed and
variable costs. When the costs are variable, the unit price for a particular
task is fixed but the volume of such tasks is not. Typically projects have a
budget that assumes a number of units for each task, but the client retains the
right to alter the scope of the project as it develops.

       When contracts are executed, IBAH typically receives an up-front payment,
which is credited against amounts due. Revenue is recognized as work units are
performed over the life of the development contract as specified in each client
contract. Subsequent billings based on project milestones or other relevant
terms such as project effort to date are also specified.

Project Backlog
- ---------------

       The Company's backlog consists of anticipated revenue from client
projects that are presently underway and/or scheduled to begin. Once work under
a client project commences, revenue is recognized over the life of the contract.
Generally, the Company includes the anticipated revenue on a project in its
backlog upon the receipt of a letter indicating the client's intention to
proceed or upon receipt of a definitive agreement covering the services.

       In general, the Company's backlog position reflects future potential
revenue streams, however, the Company believes that backlog is not a meaningful
or consistent predictor of future results. Clinical studies under contracts
included in backlog are subject to termination or delay. Clients terminate or
delay contracts for a variety of reasons including, among others, the failure of
products being tested to satisfy safety requirements, unexpected or undesirable
clinical results of the product, the decision to forego a particular study,
regulatory issues or production problems resulting in shortages of the drug.
Most of the Company's contracts are terminable upon 30 to 60 days' notice by the
client. The Company typically is entitled to receive certain fees for winding
down a study which is terminated early or delayed.

       IBAH's project backlog, in net revenue, as of December 31, 1996, was
$91.5 million, a 34% increase over the year-end 1995 of $68.5 million. Backlog
as of December 31, 1996 includes backlog resulting from the THG acquisition.

Competition
- -----------

       IBAH competes against other full service CROs. The CRO industry is highly
fragmented, with a number of full-service CROs and many small, limited-service
providers, some of which serve only local markets. Based on data assembled from
various sources, industry analysts estimate that IBAH ranks sixth worldwide
measured in terms of 1996 revenue from CRO activities. IBAH believes that it has
among the largest CRO staffs in the European market. International business
accounted for approximately 37% of the Company's 1996 CRO net revenue.

        IBAH believes that clients choose a CRO based on several factors
including reputation, references from existing clients, the client's
relationship with the CRO, experience with the particular type of project and/or
therapeutic area of clinical development, the ability to add value to the
client's development plan, the CRO's financial stability and the CRO's ability
to provide the full range of services required by the client. IBAH believes that
it competes favorably in these respects. While the fee structure is an important
consideration, IBAH believes more important factors in its business growth have
been its experience, reputation and capability to render a broad range of
services worldwide in a timely and professional manner. The Company believes it
is price-competitive with the largest, full service CROs.

        For many potential contracts, the client's threshold question is whether
to perform specific tasks internally or outsource them to a CRO. Various
economic, philosophic, cultural and organizational factors affect the decision
to use a CRO. IBAH believes that the trend toward greater outsourcing to CROs
will continue worldwide.

Foreign Currency
- ----------------

       The Company contracts with clients in various foreign currencies and
conducts its actual work with clients typically in multiple countries for each
major contract. Such activities can give rise to potential gains or losses on
specific transactions between countries where the work is conducted, which to
date have not been material. As the Company continues to grow internationally
there will be a currency risk, either favorable or unfavorable, when translating
foreign results into U.S. dollars.

Potential Liability and Insurance
- ---------------------------------

       To manage its potential liability, IBAH purchases insurance and seeks
indemnity provisions in its contracts with clients and, in some cases, with
investigators with whom it contracts on behalf of clients. The contractual
indemnities generally do not protect IBAH against certain of its own actions
such as those involving its negligence or misconduct. These indemnities are
subject to negotiation with individual clients and investigators, and their
terms and scope vary. While most of the Company's clients are large, well-
capitalized companies, the financial performance of these indemnities generally
is not secured. Therefore, IBAH bears the risk that an indemnifying party may
not have the financial ability to fulfill its obligations. In some
circumstances, IBAH indemnifies and holds harmless investigators and its clients
against liabilities incurred by them due to the actions or inactions of IBAH.
The Company currently maintains professional liability insurance which covers
all areas worldwide where IBAH does business. IBAH could be materially and
adversely affected if it were required to pay damages or incur defense costs in
connection with an indemnity claim against it or in connection with a claim that
is outside the scope of an indemnity in IBAH's favor, or beyond the level of
insurance coverage, or where an applicable indemnity in its favor is not
performed in accordance with its terms.

       Each physician-investigator retained by IBAH on behalf of a client must
agree to exercise independent medical judgment to serve the patient's interests
and medical needs, consistent with the patient's informed consent to participate
in the study. In some instances, this undertaking may obligate the investigator
to remove a patient from the study. IBAH does not assume the responsibility to
make medical determinations on patient management.

       IBAH believes that the risk of liability from patients in clinical trials
is mitigated by various regulatory requirements, including the role of
Institutional Review Boards ("IRB", an independent committee that includes both
medical and non-medical personnel) and the need to obtain each patient's
informed consent. The FDA requires clinical trials to be reviewed and approved
by an IRB. An IRB is obligated among other duties, to protect the interests of
patients enrolled in a trial.

Employees
- ---------

        As of December 31, 1996, IBAH had 755 full-time equivalents, most of
whom were employed on a full-time basis. IBAH's staff includes many experts with
advanced training in a wide variety of disciplines, including approximately 28
medical doctors and 44 people holding Ph.D. degrees in the life sciences,
biostatistics, or other related fields. IBAH conducts its own training program
for its clinical research associates, which includes both in-house activities
and supervised field training. Most of the executives and senior managers had
significant experience with pharmaceutical or biotechnology companies before
joining IBAH.


Forward-Looking Information
- ---------------------------

        This document contains, and other materials filed or to be filed by IBAH
with the Securities and Exchange Commission (the "Commission"), as well as
information included in oral statements or other written statements made or to
be made by IBAH, contain or will contain or include, disclosures which are
forward-looking statements. These forward-looking statements address among other
things, strategic initiatives based upon the Company's current plans or
expectations and are subject to a number of uncertainties and risks that could
significantly affect current plans, anticipated actions and our future financial
condition and results. These uncertainties and risks include, but are not
limited to, those relating to conducting operations in a competitive
environment; loss or delay of large contracts for regulatory or other reasons;
acquisition activities (including uncertainties associated with projecting the
synergies to be gained by the 1996 acquisitions or the ability to close any 1997
acquisitions); competition or consolidation within the pharmaceutical industry;
fluctuations in foreign currency; and general economic conditions. As a
consequence, current plans, anticipated actions and future financial condition
and results may differ from those expressed in any forward-looking statements
made by or on behalf of IBAH.


Item 2. Properties
- ------  ----------

        IBAH's principal offices and facilities, which occupy approximately
85,000 square feet of space in Blue Bell, Pennsylvania, are leased for a term
expiring in 2000. The Company also has leases covering approximately 27,000
square feet of space near Frankfurt, Germany, approximately 20,000 square feet
(a small portion of which is subject to a long-term lease) in Chippenham,
England, and smaller offices in or near Basel, Switzerland; Paris, France;
Brussels, Belgium; Sydney, Australia; Prague, the Czech Republic; Barcelona,
Spain; Copenhagen, Denmark; Durham, North Carolina; San Francisco, California;
Chicago, Illinois; Minneapolis, Minnesota; and Parsippany, New Jersey. IBAH
considers its current space to be adequate for its operations. Its leases
generally reflect market rates in their respective geographic areas.

        The Pharmaceutics Services Division's drug development services unit is
headquartered in suburban Philadelphia, where it leases approximately 20,000
square feet of office and laboratory space pursuant to a five-year noncancelable
operating lease that expires in December, 1998. To accommodate growth, this
division recently signed a lease for 124,000 square foot facility in the same
area as its current facility. The division expects to phase in operations in
this new facility over the next several years, beginning in the second quarter
of 1997.


Item 3.  Legal Proceedings
- ------   -----------------

        The Company is involved in various legal proceedings in the ordinary
course of its business, which are not anticipated to have a material adverse
effect on the Company's results of operations or financial condition.

Item 4. Submission of Matters to a Vote of Security Holders
- ------  ---------------------------------------------------

        On December 26, 1996 proxies were mailed to the Company's security
holders in connection with a Special Meeting of the Stockholders held on
February 5, 1997. The meeting was held to consider a proposal to approve the
Company's 1997 Equity Compensation Plan (the "Plan").

        The Plan provides for the grant of incentive stock options ("ISOs") and
non-qualified stock options ("NQSOs") (collectively, "Options") to designated
employees, including employee members of the Board of Directors, key advisers
who render bona fide services to the Company (but not in connection with the
offer or sale of securities in capital-raising transactions), and non-employee
directors (there are approximately seven non-employee directors) (collectively,
"Participants"). Only employees are eligible to receive grants of ISOs under the
Plan. Those Participants to receive Options are selected by a committee composed
of two or more persons who are appointed by the Board of Directors and who are
not employees of the Company (the "Committee"). All Options granted to non-
employee directors must be ratified or approved by the Board of Directors.

        The maximum number of shares of Common Stock which may be issued by the
Company under the Plan is 1,500,000 and the maximum number of shares any
individual may receive under the Plan during a calendar year is 200,000.

        The Plan was approved by the stockholders with a vote of 16,744,052
shares in favor of the proposal, 2,313,074 against and 7,055 abstaining.

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


Overview
- --------

        The Company began operations in December 1985, through its predecessor
Bio-Pharm Clinical Services, Inc. ("Bio-Pharm"), and has achieved its growth
through internal development and acquisitions.

        The Clinical Services Division, the core of IBAH, is a full service CRO
that serves the pharmaceutical, biotechnology, medical device and diagnostics
industries in accelerating the development and commercialization of new products
worldwide. This division's primary services are designing product development
programs, managing pre-clinical studies, design and conduct of clinical trials,
clinical data management and biostatistical analysis, writing reports of study
findings, health economics analysis and post-marketing studies, and regulatory
affairs.

        This division began operations in December, 1985 and derives its
revenues by providing services on a contractual basis to its clients. The
division's worldwide staff is based in offices in the United States, Germany,
United Kingdom, Switzerland, France, Belgium, Spain, the Czech Republic, Denmark
and Australia. Through a joint venture with a Russian company, IBAH also
operates an office located in Russia. With its current operations in Europe, the
Company is positioned to service all of Western and Eastern Europe, including
Russia. Additional locations, demonstrated by the Company's recent signing of a
definitive agreement to purchase one of the leading CROs in Australia, will be
evaluated based on client needs.

        Overall, the Company has grown its international business significantly
over the past several years to approximately 37% of 1996 worldwide CRO net
revenues. While the growth of its international organization has taken
significant management and financial resources, the Company believes that the
CRO industry is increasingly a global service industry. Accordingly, the ability
to perform clinical services and ancillary services on a global basis is a
strategic focus of the Company.

        In October, 1996, the Company acquired THG, a CRO focusing on clinical
trials management and clinical monitoring. THG, which has been integrated into
the Clinical Services Division, adds critical mass and management talent to the
Company, enhancing its ability to obtain and perform large clinical trials. The
Company also signed a definitive agreement to purchase one of the leading
Australian CROs, Pharmaco Pty., Ltd., ("Pharmaco"), on February 28, 1997.
Pharmaco's 1996 revenues were approximately $1.2 million. The closing of this
acquisition is contingent upon the completion of due diligence. Once the
acquisition of Pharmaco is completed, the Company plans to integrate its
operations with the Company's current Australian office, adding depth and
strength to IBAH's Australian and Pacific Rim capabilities.

        In July, 1996, the Company acquired RBI, a data management and software
company. RBI develops and markets software to increase the speed and efficiency
of clinical development. The RBI acquisition adds additional tools that are
designed to enhance the processing and analysis of clinical trials data for IBAH
and its clients. RBI offers software tools ranging from archiving, optical
imaging and work flow processing software to tools that facilitate data clean
up, data pooling and data reporting.

        The Pharmaceutics Services Division was acquired through the Merger and
provides traditional product formulation and analytical, stability and other
manufacturing related services (the manufacture of trial drugs, among others) to
the same market as the CRO division. This division performs process development
for manufacturing, manufacture of dose forms for clinical trials, testing of
dose forms for shelf life stability and conformance with product specifications
and other chemical and physical properties required in drug development and
registration. The division operates from a manufacturing and office facility
located in suburban Philadelphia. The Company believes the demand for this
division's services will continue to grow as more companies look to out-source
pharmaceutical services.

                                       18

        The Company contracts with clients in various foreign currencies and
typically conducts its actual work with clients in a number of different
countries for each major contract. Such activities can give rise to potential
gains or losses on specific transactions between countries where the work is
conducted, which to date have not been material. The Company's International
operations give rise to a currency risk, either favorable or unfavorable, when
translating results into U.S. dollars. However, since the Company's service
contracts are based in local currency, typically in the country where the client
contracts the work, there is additional currency exposure either favorable or
unfavorable within the International CRO in the form of transaction gains or
losses between currencies. For these types of transactions, the Company may
consider foreign currency hedging as a mechanism to protect exposures in a given
currency as they relate to foreign or U.S. dollar currency.

</TABLE> 



Year ended December 31, 1996 as compared to December 31, 1995

        Revenues earned from client projects are recognized on a percentage of
completion basis generally related to units of work or hours of completed
project work. For clinical studies, the CRO typically contracts on behalf of its
clients with third party independent investigators, usually physicians, and with
other third party providers of laboratory services or other specialized
services. These costs are passed through to clients, and in accordance with the
Company's policy are included in total revenues, but not in its net revenues.

        Total revenues in 1996 were $82,609,000, an increase of 45.0% over 1995
results. Net revenues were $62,156,000 for the year ended 1996, an increase of
45.0% over the comparable 1995 period, the rate of growth being identical to
that of total revenues. Excluding acquisitions, internal revenue growth was
34.6%, while net revenue growth was 33.9%. The increase in net revenues was
principally due to the growth of the U.S. CRO business (an increase of 50.5%,
although without the THG and RBI acquisitions the increase was 30.2%); dramatic
growth in the Pharmaceutics business (an increase of 131%); and continued growth
in the International CRO (an increase of 24.1%). The increase in net revenues
from year to year reflects the continued growth in outsourcing of CRO services
by pharmaceutical and biotechnology companies as well as the benefit of the THG
and, to a lesser extent, the RBI acquisitions.

        Direct expenses were $30,960,000, or 49.8% of net revenues in 1996 as
compared to 55.6% of net revenues in 1995. As a result, direct expenses
increased by 29.8% in 1996 over 1995, while net revenues increased by 45.0% for
the same period. Excluding acquisitions, direct expenses increased 19.5%. The
improvement in the ratio of direct expenses was made in all operating units,
principally in the Pharmaceutics Services Division, where additional volume
increased the utilization of capacity in this division, hence the improvement in
margins. Direct expenses are classified as those expenses that are directly
related to revenue producing departments.

                                       19
<PAGE>
 
        Selling, general and administrative expenses were $30,121,000, or 48.5%
of net revenues as compared to a 1995 ratio of selling, general and
administrative expenses to net revenues of 51.1%. Accordingly, selling, general
and administrative expenses increased by 37.4% as compared to net revenue growth
of 45.0%. Excluding acquisitions, selling, general and administrative expenses
increased 26.0%. The amortization of goodwill for the THG and RBI acquisitions
account for 1.6% of the 1996 increase. Total depreciation and amortization
expenses included in this figure were $2,988,000 in 1996 as compared to
$2,003,000 in 1995. The improvement in the ratio of selling, general and
administrative expenses as a percentage of net revenues was principally due to
spreading these expenses over a larger business volume.

        Non-recurring acquired research and development expense in 1996 was
$510,000 versus no equivalent expense in 1995. The non-cash charge incurred in
1996 was directly related to the acquisition of RBI, accounted for as a purchase
transaction. This charge represents the portion of the RBI purchase price
allocated to software research and development.

        Accordingly, total operating expenses in 1996 were $61,591,000, or 99.1%
of net revenues as compared to operating expenses in 1995 that exceeded net
revenues. Without the non-recurring acquired research related to the acquisition
of RBI total expenses were 98.3% of net revenues.

        In 1996, the Company reported consolidated operating profit for the
first time since being a public company of $565,000 ($1,075,000 from continuing
operations if the acquired research from the acquisition of RBI is excluded) as
compared to an operating loss from continuing operations of $2,902,000 in 1995.
The substantial improvement in operating results was principally due to the
continued improvement in operating results for the U.S. CRO as well as the
maturation of the Pharmaceutics Services Division from a loss in 1995 to a
profit in 1996. Operating results from continuing operations improved once again
by quarter during 1996 as follows: first quarter-operating loss of $242,000;
second quarter-operating profit of $14,000; third quarter-operating profit of
389,000 (excluding the $510,000 RBI acquired research and development charge);
and fourth quarter-operating profit of $914,000.

        Interest income, net of interest expense, was $475,000 in 1996 as
compared to net interest expense of $111,000 in 1995. The improvement from a net
interest expense to a net interest income position from 1995 to 1996 was
principally due to the improvement in operating results from a loss in 1995 to a
profit in 1996, and the successful completion of a public equity offering in
April 1996 which netted the Company $18 million. The net cash improvement due to
the public offering was partially offset in October 1996 by the $14 million cash
portion of the THG acquisition.

        There were no losses associated with discontinued operations in 1996. In
1995, losses from discontinued operations were $1,546,000, due entirely to the
Drug Delivery business which was divested in July, 1995.

        Income taxes were $60,000 in 1996 and were related to state income taxes
due from profitable operations in the U.S. There were no federal income taxes in
1996 as the Company had sufficient net operating loss carryforwards to offset
any federal taxes due on U.S. profits.

        Net income for 1996 was $980,000, or $.04 per share as compared to a
loss from continuing operations in 1995 of $3,013,000, or $.21 per share. If the
one-time charge for acquired research related to the RBI acquisition were
eliminated, net income was $1,490,000 or $.06 per share.

The information present in the above table does not purport to be indicative of
future results of operations.

(1) Includes the operating results of RBI since the July 18, 1996 acquisition
date and that of THG since the October 1, 1996 acquisition date.

           Net revenues for the U.S. CRO were $35,260,000 in 1996, an increase
of 50.5% over 1995. Internal growth in 1996 over 1995 was 30.2% (excluding the
THG and RBI acquisitions whose results are included only since acquisition).
Both direct and indirect expenses improved as a percentage of net revenue due to
operational efficiencies, the completion of a major project, and the leveraging
effect of incremental increases in revenue volume. As a result, operating profit
before the one-time RBI acquired research and development charge improved to
9.0% of net revenues, an improvement of 247% over 1995.

           International net revenues were $20,895,000 in 1996, an increase of
24.1% over 1995 results. While revenue volume increased, the operating loss of
$2,688,000 of this division was essentially the same year over year. The
performance in 1996 was negatively impacted by the Company's largest project
being placed on hold during the middle of 1996. This hold status was due to
certain regulatory issues surrounding the drug and out of the control of the
Company. As a result, the Company was not able to earn significant revenues from
this project in the second half of 1996, while staff had been recruited and
dedicated to this project. In early January, 1997 the project was taken off hold
status and the Company commenced work on this project in late first quarter of
1997, the scope of which is expected to increase quarterly during 1997.

           The Pharmaceutics Services net revenues were $6,001,000 in 1996, an
increase of 131% over 1995. The improvement resulted from the continued demand
for outsourcing of these services and the fact that 1995 was the first full year
of operation. By utilizing more of its facility's capacity, the division was
able to record operating profit of $594,000, or 9.9% of net revenues in 1996, as
compared to an operating loss of $1,379,000 in 1995.

                                       21

Year ended December 31, 1995 as compared to December 31, 1994

          Total revenues in 1995 were $56,985,000, an increase of 13.7% over
1994. Net revenues in 1995 were $42,866,000, an increase of 27.5% over 1994. The
increase in net revenues was principally due to the dramatic growth recorded by
the Company in its European operations which increased due to research and
development out-sourcing by European pharmaceutical companies. In addition, the
Pharmaceutics Division increased net revenue by 266% to $2,594,000 in 1995 as
1994 was a start-up year. Net revenues in 1995 represented the first full year
of operations for this division.

          Direct expenses were $23,847,000 in 1995, or 55.6% of net revenues as
compared to 57.5% of net revenues in 1994. As a result, direct expenses
increased 23.3% in 1995 over 1994, while net revenues increased 27.5%. The
improvement in the ratio of direct expenses was made in the CRO where volume
increases in the International CRO and efficiency improvements overall increased
margins. These improvements were slightly offset by the Pharmaceutics Services
Division where direct expenses were higher than revenues because the division
was still maturing and its facility was not fully utilized.

          Selling, general and administrative expenses were $21,921,000, or
51.1% of net revenues, an increase from 47.2% of net revenues in 1994. Overall,
selling, general and administrative expenses increased 38.2% in 1995 over 1994
due to increased expenses in the U.S. CRO. The increase in U.S. CRO expenses was
offset by a decrease, as a percentage of net revenues, in the International CRO
and the Pharmaceutics Services Division. The increase in the U.S. CRO expenses
was largely related to corporate expenses as 1995 was the first full year as a
public company. Offsetting this increase were decreases in the percentage of net
revenues in both the International CRO and the Pharmaceutics Services Division,
due to significant revenue growth from year to year.

          Non-recurring acquired research and development expense of $18,297,000
was recorded in 1994. This amount represents the excess of the Affinity purchase
price over the estimated fair value of the net assets acquired.

          Total operating expenses were $45,768,000, an increase of 30.0% over
total operating expenses (excluding the one-time Affinity acquired research and
development charge) in the prior year.

          Net operating loss in 1995 was $2,902,000 as compared to a loss of
$19,883,000 in 1994. Excluding the one-time Affinity acquired research and
development charge in 1994, the 1994 operating loss was $1,586,000, resulting in
an increase in operating loss of $1,316,000 in 1995 over 1994. The increase in
operating loss was due to increases in administrative expenses in the U.S.
CRO business because of inflation factors and increases in corporate overhead.

          Net interest expense was $111,000 in 1995 due principally to cash
requirements to fund losses in the International CRO, Pharmaceutics Services and
Drug Delivery divisions in the first half of 1995. In July, 1995, the Drug
Delivery business was divested and in August, 1995, the Company raised $7
million in a private equity financing (See Notes 4 and 5 to Notes to
Consolidated Financial Statements for details). In 1994, the Company recorded
net interest expense of $86,000.

          Loss from discontinued operations was $1,546,000 in 1995 as compared
to $1,245,000 in 1994. This loss was entirely attributed to the Drug Delivery
business which was divested in July, 1995. The financial statements for all
periods have been restated to eliminate this business and indicate net losses
from discontinued operations as a separate line-item in the statement of
operations. The 1995 loss reflected loss from operations for the first seven
months of 1995 as well as reserves for reasonably anticipated expenses resulting
from the sale of this division.

          Net loss for 1995 was $4,559,000 in 1995 as compared to a loss of
$21,214,000 in 1994. Excluding the one-time Affinity acquired research and
development charge, the 1994 net loss was $2,917,000.

The information present in the above table does not purport to be indicative of
future results of operations.

          Net revenues for the U.S. CRO were $23,428,000 in 1995, a decrease of
1.8% over 1994 net revenues. The slight decline in revenues was largely due to
delays in several major projects. Direct expenses as a percentage of net
revenues decreased in 1995 to 50.3% from 55.6% in 1994. The decrease was a
result of cost reduction measures due to lower than anticipated revenue volume
growth. Selling, general and administrative expenses, after allocation of
corporate expenses to other business units, increased in 1995 to 45.8% of net
revenues from 39.8% in 1994. The increase was principally due to increased
corporate expenses as 1995 represented the first full year as a public Company.

          International CRO net revenues were $16,844,000, an increase of 85.9%
over 1994 net revenues. The dramatic increase was due to increased outsourcing
of CRO services by European pharmaceutical companies and that the fact the
Company was positioned to benefit from this trend. Direct expenses were 53.9% of
net revenues in 1995, an improvement from 58.5% in 1994, due to volume-related
efficiencies of scale. Selling, general and administrative expenses were 60.5%
of net revenues, a slight improvement from 61.3% in 1994. The rate of overhead
spending in International reflects the continued commitment to building
infrastructure.

Liquidity and Capital Resources
- -------------------------------

           As of December 31, 1996, the Company had cash and short-term
investments of $20.8 million as compared to $8.3 million as of December 31,
1995. Working capital was $9.2 million as of December 31, 1996, an improvement
of 98% over 1995. As of December 31, 1995, working capital was $4.6 million. In
April, 1996, the Company raised net proceeds of $18 million in equity financing
from the completion of a public offering of common stock to institutional
investors. In October, 1996, the Company acquired THG for cash and stock,
requiring a cash payment of $14 million. It is the Company's belief that it has
sufficient resources from existing cash flow that it will not need additional
cash for working capital purposes through an equity or debt offering.

           Although the Company does not believe that it requires financing for
working capital purposes, it may seek additional cash infusions for aggressive
expansion of operations for competitive reasons or to prepare for certain
capital needs for strategic acquisitions. The Company intends to reinvest any
positive cash flow from operations to support operations through additional
capital spending to improve its competitive position.

                                       23

           Based on the foregoing and other factors, and while there can be no
assurance that external financing will be available on terms acceptable to the
Company, the Company believes that it has, or has access to, adequate working
capital to meet its strategic objectives and fund its operations for the
foreseeable future (see Note 10 of Notes to Consolidated Financial Statements
regarding the Company's line of credit facilities).

                    REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS





To IBAH, Inc.:

We have audited the accompanying consolidated balance sheets of IBAH, Inc. (a
Delaware corporation) and subsidiaries as of December 31, 1995 and 1996, and the
related consolidated statements of operations, stockholders' equity (deficit)
and cash flows for each of the three years in the period ended December 31,
1996. These financial statements are the responsibility of the Company's
management. Our responsibility is to express and opinion on these financial
statements based on our audits.

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

In our opinion, the financial statements referred to above present fairly, in
all material respects, the financial position of IBAH, Inc. and subsidiaries as
of December 31, 1995 and 1996, and the results of their operations and their
cash flow for each of the three years in the period ended December 31, 1996, in
conformity with generally accepted accounting principles.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
                   ------------------------------------------

1.  BACKGROUND
    ----------

IBAH, Inc. ("IBAH" or the "Company") provides a comprehensive range of product
development services worldwide for clients in the pharmaceutical, biotechnology,
medical device and diagnostics industries. The Company's principal activity is
to help its clients meet the complex regulatory requirements that must be
satisfied before a new product may be commercially marketed. The Company offers
clients access to extensive regulatory affairs and clinical development services
on an international scale through its Bio-Pharm Clinical Services ("the Clinical
Services Division"). The Company also provides pharmaceutical manufacturing and
stability testing services through Bio-Pharm Pharmaceutics Services ("the
Pharmaceutics Services Division"). The Bio-Pharm Drug Delivery Services Division
("the Drug Delivery Services Division") was divested on July 28, 1995 (see Note
5).


2.  SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
    ------------------------------------------


Principles of Consolidation

The accompanying financial statements include the accounts of IBAH, Inc., and
its subsidiaries. All material intercompany balances and transactions have been
eliminated.

Use of Estimates

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

Reclassifications

Certain reclassifications have been made to the prior years' financial
statements to conform to the current year presentation.

                                      F-7
<PAGE>
 
Translation of Foreign Financial Statements

Assets and liabilities of the Company's foreign operations are translated at the
year-end rate of exchange, and the income statements are translated at the
average rate of exchange for the year. Gains or losses from translating foreign
currency financial statements are accumulated in a separate component of
stockholders' equity.



Cash, Cash Equivalents and Investments

The Company considers all highly liquid investments purchased with remaining
maturities of three months or less to be cash equivalents.

Investments are held at market value, and at December 31, 1995 and 1996 were
classified as short-term. Cash, cash equivalents and investments consisted of
the following:

The repurchase agreement matured on January 2, 1997 and was secured by U.S.
government securities.  The short-term investments outstanding on December 31, 
1996 all mature in 1997.

The Company adopted Statement of Financial Accounting Standards No. 115,
"Accounting for Certain Investments in Debt and Equity Securities," effective
January 1, 1994. This statement requires the Company to classify its investment
securities as: (1) held to maturity, (2) available for sale or (3) held for
trading purposes. At December 31, 1995 and 1996, all of the Company's short-term
investments are classified as available for sale, therefore any unrealized
holding gains or losses should be presented in a separate component of
stockholders' equity. At December 31, 1995 and 1996, there were no significant
unrealized holding gains or losses.

consolidated as a result of the merger with Affinity Biotech, Inc. ("Affinity")
and the acquisition of European Pharmaceutical Investigation Consultants, Ltd.
("EPIC") in 1994 and the acquisitions of Resource Biometrics, Inc. ("RBI") and
HGB, Inc., doing business as The Hardardt Group ("THG") in 1996 (see Note 6):

</TABLE> 

During 1994, the Company assumed a note in the amount of approximately $483,000
related to leasehold improvements made to its German office (see Note 11).

In connection with the merger with Affinity, the Bio-Pharm warrants to purchase
preferred stock were exercised using the principal from the 8% subordinated
notes. The preferred stock was then converted into common stock. In addition,
the Bio-Pharm treasury stock was retired in conjunction with the merger.


Accounts and Unbilled Receivables

The Company considers accounts and unbilled receivables as reported to be
collectible and realizable. As of December 31, 1995 and 1996, the allowance for
doubtful accounts was $350,000 and $524,000, respectively. Prior to 1994, no
allowance for doubtful accounts was recorded. Approximately $400,000 and
$190,000 of write-offs were charged to this allowance which was offset by
approximately $200,000 and $360,000 charged to current year earnings in 1995 and
1996, respectively. If accounts or unbilled receivables become uncollectible or
unbillable, the Company's policy is to charge these write-offs against this
allowance. The Company continually reviews the realizability of its receivables
and charges current period earnings for the amount deemed unrealizable.

                                      F-9

Property and Equipment


Property and equipment are carried at cost. Improvements and betterments are
capitalized, and maintenance and repairs are charged to expense as incurred. The
Company provides depreciation and amortization using principally the
straight-line method for financial reporting purposes using the following
estimated lives:

              Furniture and fixtures                   5 years
              Leasehold improvements                   Remaining term of lease
</TABLE> 


Long-lived Assets

The Company adopted Statement of Financial Accounting Standards No. 121,
"Accounting for the Impairment of Long-lived Assets to be Disposed of,"
effective January 1, 1996. This statement requires that long-lived assets and
certain identifiable intangibles to be held and used or disposed of by an entity
be reviewed for impairment whenever events or changes in circumstances indicate
that the carrying amount of an asset may not be recoverable. The Company has
determined that no impairment loss need be recognized for applicable assets of
continuing operations (see Note 6).


Revenue Recognition and Concentration of Credit Risk

Substantially all revenues are earned by performing services under contracts
from various pharmaceutical, biotechnology, medical device and diagnostics
companies. Certain contracts require the Company to perform services for a
specified number of patients or data records. Revenues are recognized based on
the status of the work completed as of a given time as a percentage of the total
tasks required under the contract. Billings and payments are specified in the
contract. Other contracts include specified components for which the Company is
to be reimbursed for time and expenses. Clients are billed monthly for such time
and expenses and revenues are recognized as the time is incurred.

Over the last three years, four of IBAH's clients accounted for 10% or more of
its revenues in any given year. In 1994, three individual clients accounted for
14.7%, 13.1% and 10.4% of the Company's revenues, respectively. In 1995, two
individual clients accounted for 14.9% and 10.2% of the Company's net revenues,
respectively. In 1996, one individual client accounted for 20.4% of the
Company's net revenues.

The concentration of credit risk is limited to trade accounts receivables and is
subject to the financial and industry conditions of the Company's clients. The
Company does not require collateral or other securities to support client
receivables.

Expense Recognition

A portion of expenses are incurred under contracts with physicians. The
contracts call for the physicians to perform certain procedures or tests on a
specified number of patients. Expenses are recognized based upon the status of
the work completed as of a given time as a percentage of the total procedures
required under the contract. Included in reimbursed costs in the accompanying
consolidated statements of operations are principally the contracted physicians'
costs. Billings and payments are specified in the contract.

                                      F-10
<PAGE>
 
Start-up Expenses

Included in selling, general and administrative expenses during 1994 are
$814,000 of start-up expenses which represent the costs incurred in forming the
Pharmaceutics Services Division until its facility had completed the necessary
validations in compliance with the Food and Drug Administration's Good
Manufacturing Practices during the third quarter of 1994. These costs included
primarily salaries, consulting fees and office rent.

Income Taxes

On January 1, 1994, upon terminating its S Corporation status, the Company
adopted Statement of Financial Accounting Standards No. 109, "Accounting for
Income Taxes," (SFAS 109) retroactively to inception. This statement requires
the use of the liability method in accounting for income taxes. Under this
method, deferred tax assets and liabilities are determined based on differences
between the financial reporting and tax bases of assets and liabilities, and are
measured using enacted tax rates that are expected to be in effect when the
differences reverse. The adoption of SFAS 109 had no material impact on the
Company's financial statements.

Net Income (Loss) per Share

Net income per share is computed using the weighted average number of common
stock shares outstanding plus common stock equivalents. Net loss per share is
computed using the weighted average number of common stock shares outstanding.
For 1994 and 1995 common stock equivalents are antidilutive and have not been
considered in the net loss per share computation. Interest expense related to
the 8% subordinated notes which were converted in conjunction with the merger
with Affinity (see Note 6) has been excluded from the 1994 net loss per share
calculation. In conjunction with the merger with Affinity, all Bio-Pharm shares
of common stock were converted into 16.4679 shares of IBAH common stock. All
common share and per share amounts have been adjusted retroactively to give
effect to the merger.


3.  1996 PUBLIC OFFERING OF COMMON STOCK
    ------------------------------------

On April 19, 1996, the Company completed a public offering of 3,000,000 shares
of its common stock, par value $.01 per share, at an issuance price of $6.50 per
share for a total of $19.5 million. The net proceeds to the Company, after all
issuance expenses, were $18,011,000. These shares were sold to selected
institutional investors.

4.    1995 PRIVATE EQUITY PLACEMENT
      -----------------------------

On August 11, 1995, the Company completed a private equity placement of 999,554
shares of convertible preferred stock, par value $.01 per share, at a purchase
price of $7.003125 per share for a total of $6,935,000, net of transaction
costs. Each share of convertible preferred stock is convertible into three
shares of common stock. Each share of convertible preferred stock is entitled to
three detachable and transferable warrants to purchase shares of common stock
for $2.33 per share on or before August 11, 2000. In addition, each share of
convertible preferred stock is entitled to the voting equivalent of three shares
of common stock. The convertible preferred stock may be converted at the
Company's option after August 11, 1998, provided that the common stock has a
trading price equal to or greater than $10 per share. On October 10, 1995, the
Company filed a registration statement on Form S-3 with the Securities and
Exchange Commission for the common stock underlying the convertible preferred
stock and warrants. The registration of these securities was declared effective
on October 31, 1995. In the event the Company sells or issues additional shares
of common stock, warrants or other rights to purchase stock, stockholders of
convertible preferred stock are entitled to certain anti-dilution protection.
The holders of the convertible preferred stock are entitled to one seat on the
Company's Board of Directors, which was filled in August 1995.

In 1996, 249,889 shares of the convertible preferred stock were converted into
749,667 shares of common stock.


5.    DIVESTITURE OF DRUG DELIVERY SERVICES DIVISION
      ----------------------------------------------

On July 28, 1995, the Company entered into an agreement to sell its Drug
Delivery Services Division effective July 1, 1995 to a management group from
that Division. The Drug Delivery Services Division had recorded a net loss of
$727,000 for the six months ended June 30, 1995. In addition a loss on disposal
of the Division of $819,000, including accruals for severance payments and
future liabilities, has been reflected in the consolidated statement of
operations for 1995. The operating losses of the Drug Delivery Services Division
have been retroactively restated as losses from discontinued operations in the
accompanying consolidated statements of operations. The Drug Delivery Services
Division was a significant portion of Affinity Biotech, Inc. (see Note 6).

6.    MERGERS AND ACQUISITIONS
      ------------------------

Merger with Affinity Biotech, Inc.

On April 27, 1994, the merger ("the Merger") between Affinity Biotech, Inc.
("Affinity") and Bio-Pharm Clinical Services, Inc. ("Bio-Pharm") was
consummated. Simultaneous with the Merger, Affinity changed its name to IBAH.
Since the Merger resulted in the former Bio-Pharm shareholders having a majority
ownership of the merged entity, the Merger has been accounted for as a purchase
transaction with Bio-Pharm treated as the acquirer.

Concurrent with the Merger, Bio-Pharm's 8% subordinated notes were converted
into preferred stock and then converted into Bio-Pharm common stock (see Note
13). Bio-Pharm's common stock was then exchanged for shares of common stock of
the Company. Immediately prior to the Merger, an additional 74,737 shares of
Bio-Pharm common stock were sold and issued to institutional investors in
connection with a $4,000,000 private placement. These shares were subsequently
converted into 1,230,761 shares of common stock of the Company.

The total purchase price of Affinity was $22,714,000, which consisted of the
following: (i) the $18,929,000 market value of the outstanding shares of
Affinity common stock (5,408,249 shares of common stock multiplied by $3.50 per
share, which represented the closing price on April 26, 1994), (ii) the $937,000
fair value of the outstanding Affinity options and warrants to purchase Affinity
common stock, (iii) the $698,000 fair value of the warrants issued to certain
venture investors to purchase shares of Bio-Pharm common stock, which warrants
were converted into warrants to purchase 684,505 shares of Company common stock
at $2.58 per share and (iv) transaction costs and an accrual for Affinity-
related severance costs totaling $2,150,000. Since Bio-Pharm is the acquirer for
accounting purposes, the Affinity options and warrants are required to be valued
for purchase accounting purposes. The fair value of the warrants issued to the
venture investors are included in the purchase price because those warrants were
issued to the investors in connection with their approval of the Merger. By
January 1997, all such warrants issued to the Bio-Pharm venture investors were
exercised (see Note 13). The total Affinity purchase price has been allocated to
the fair market value of the assets acquired and liabilities assumed. The book
value of Affinity's assets and liabilities approximates their fair market value.
Such estimate of fair market value may be revised at a later date. The
$18,297,000 excess of the purchase price over the estimated fair market value of
the net assets acquired was allocated to acquired research and development and,
accordingly, was charged to the statement of operations.

Acquisition of European Pharmaceutical Investigation Consultants Limited
("EPIC")

On January 4, 1994, Bio-Pharm purchased all of the outstanding shares of stock
of EPIC for $700,000 in cash and 1,547,703 shares of common stock with an
appraised value of $2,900,000. The acquisition was recorded using the purchase
method of accounting. The total purchase price of $3,765,000, including
transaction costs of $165,000, was allocated to the fair market value of the
assets acquired (which included $871,000 of cash) and liabilities assumed. The
book value of EPIC's assets and liabilities approximate their fair market value.
The $3,320,000 excess of the total purchase price over the estimated fair market
value of the net assets acquired was treated as goodwill and is being amortized
on a straight-line basis over 20 years. As of December 31, 1995 and 1996, the
accumulated amortization of goodwill related to EPIC was $332,000 and $498,000,
respectively.

Acquisition of Resource Biometrics, Inc. ("RBI")

On July 18, 1996, the Company purchased all of the outstanding shares of stock
of RBI for an initial consideration of 350,000 shares of the Company's common
stock. RBI is a provider of software products and data services to the
pharmaceutical, biotechnology and medical device industries. RBI's software
tools are used to increase the efficiency of data clean-up, database
consolidation, data analysis and reporting. The acquisition was recorded using
the purchase method of accounting. The total purchase price of $2,463,000,
including estimated transaction costs of $174,000, was allocated to the fair
value of the assets acquired and liabilities assumed. The $2,718,000 excess of
purchase price over book value on the acquisition date was allocated based on an
independent appraisal as follows: (1) $510,000 to acquired research and
development, which is charged to the statement of operations as a non-recurring
item; (2) $160,000 to software technology being amortized over 5 years; and (3)
$2,048,000 to goodwill being amortized over 20 years. Such allocation may be
revised at a later date if events and circumstances arise indicating a required
change. The results of RBI's operations are consolidated with those of the
Company effective the acquisition date.

Additional consideration may be payable to the former shareholders of RBI in the
form of shares of the Company's common stock. This additional consideration is
contingent on RBI exceeding certain earnings levels related to software
products, as defined in the acquisition agreement, during the years ended
December 31, 1997 through 1999. Any payments made under this contingency will be
accounted for as additional purchase price.

As of December 31, 1996, the accumulated amortization of goodwill related to the
RBI acquisition was $47,000.

Acquisition of HGB, Inc., doing business as The Hardardt Group ("THG")

On October 1, 1996, the Company purchased all of the outstanding shares of stock
of THG for $14 million in cash and 2,719,999 shares of the Company's common
stock. The former stockholders of THG are restricted from selling their IBAH
common stock for a six-month period. THG is a provider of clinical trials
management and clinical monitoring services to the pharmaceutical, biotechnology
and medical device industries. THG provides these services predominantly in the
U.S. This acquisition was recorded under the purchase method of accounting. The
total purchase price of $31,007,000, including estimated transaction costs of
$1,569,000, has been allocated to the fair value of assets acquired and
liabilities assumed. The book value of THG's assets and liabilities approximate
their fair value. The $30,048,000 excess of purchase price over book value on
the acquisition date was allocated to goodwill. Goodwill is being amortized on a
straight-line basis over 25 years, based on an independent appraisal obtained by
the Company. As of December 31, 1996, the accumulated amortization of goodwill
related to the THG acquisition was $300,000.

Subsequent to these acquisitions, the Company continually evaluates whether
later events and circumstances have occurred that indicate the remaining
estimated useful life may warrant revision or that the remaining balance of
goodwill may not be recoverable. If factors indicate that goodwill should be
evaluated for possible impairment, the Company will use an estimate of the
related undiscounted cash flows over the remaining life of the goodwill in
measuring whether the goodwill is recoverable. As of December 31, 1996, the
Company has determined that the goodwill related to the EPIC, RBI and THG
acquisitions is recoverable.

The following table summarizes the unaudited pro forma combined results of
operations for the years ended December 31, 1995 and 1996, assuming that the
acquisitions of RBI and THG and the divestiture of the Drug Delivery Services
Division (see Note 5) had occurred on January 1, 1995:

Drug Delivery Services Division of $1,546,000 due to the Company's decision to
discontinue the operations of that division.

The shares used in computing pro forma net loss per share assumes that the
acquisitions of RBI and THG had occurred on January 1, 1995.

9.    INCOME TAXES
      ------------

At December 31, 1996, the Company had net operating loss carryforwards for U.S.
income tax purposes of approximately $9,400,000 and for foreign income tax
purposes of approximately $6,000,000. If utilized, $3,200,000 of the U.S.
Federal net operating loss carryforward will not be benefited in the statement
of operations as it was generated by the exercise of nonqualified stock options
and will be recorded directly to additional paid-in capital in accordance with
SFAS 109. The Federal net operating loss carryforwards will expire at various
dates beginning in 2008, if not utilized.

Pursuant to the Tax Reform Act of 1986, annual use of the Company's U.S. Federal
net operating loss carryforwards may be limited if a cumulative change in
ownership of more that 50% has occurred within a three-year period. Upon
consummation of the Merger, the availability in any one year of Affinity's net
operating loss carryforward will be limited due to a change in ownership. Such
limitation will not have an effect on the Company's ability to ultimately
utilize this carryforward. The Company believes that no such change has taken
place since the Merger.

The components of income(loss) before income taxes are as follows:

The income tax provision for the year ended December 31, 1996 relates entirely
to the state income taxes due to profitable operations in the U.S. The income
tax provision is composed of a current provision of $109,000 offset by a
deferred benefit of $49,000.

Income taxes computed at the Federal tax rate of 34% are reconciled to the total

A valuation allowance has been provided, as the realization of the deferred tax
assets is uncertain. The deferred tax liability relates to temporary differences
at THG for state taxes purposes. The Federal liability related to these THG
temporary differences has been benefited against the Company's Federal net
operating loss carryforwards.

10.   LINE OF CREDIT
      --------------
  
On July 8, 1994, the Company replaced its previously existing $2,000,000 line of
credit and note payable with a new loan agreement with another bank. With this
new agreement, the Company obtained a revolving line of credit in the amount of
$2,000,000, a non-revolving equipment term loan in the amount of $2,500,000 and
an additional term loan in the amount of $282,000 (see Note 11). In August 1996,
the Company renegotiated its banking relationship. The Company now maintains a
$5,000,000 credit facility with its bank. This facility is comprised of the
previously existing equipment term loans and a line of credit. The availability
under the line of credit is equal to $5,000,000 minus the outstanding balance on
the term loans, or $3,428,000 at December 31, 1996.


                                     F-16
<PAGE>
 
These credit facilities, as amended during 1995 and 1996, carry various terms
and conditions. Interest on amounts borrowed under the line of credit, equipment
and term loan facilities accrued at an annual rate equal to the lender's prime
rate (8.5% at both December 31, 1994 and 1995 and 8.25% at December 31, 1996)
plus 0.25%, prime plus 0.75% and prime plus 0.75%, respectively. Indebtedness
under these facilities is secured by substantially all of the Company's assets,
and in the case of the equipment facility also includes a purchase money
security interest in the equipment purchased. The facility contains financial
and operational covenants to maintain specified levels of working capital, cash
level, debt service and debt-to-tangible net worth ratio.

At December 31, 1994 and at certain times in 1995, the Company was not in
compliance with certain financial covenants required by the loan agreement.
Waivers were obtained by the Company in each instance of noncompliance. During
1995 and 1996, the Company renegotiated its bank loan financial covenants and is
currently in compliance with all covenants.

There were no borrowings under the line of credit facility in 1994, 1995 or
1996.

The non-revolving equipment loan is for capital expenditures made in 1994 and is
payable in 48 equal payments of $52,083 plus interest beginning July 1995. It is
subject to the same restrictive covenants and terms as stated in Note 10. As
stated in Note 10, the note bears interest at the lender's prime rate (8.5% at
both December 31, 1994 and 1995 and 8.25% at December 31, 1996) plus 0.75%.

The note payable to bank includes a note from 1993 that was assumed by a new
lender in 1994. The note is secured by substantially all of the Company's
assets, and is subject to the same restrictive covenants as discussed in Note
10. Payments on this note are $9,399 per month plus interest at the lender's
prime rate plus 0.75%.

The note payable on leasehold improvements is for approximately $483,000 of
improvements made in Germany. It is payable in 60 equal payments of
approximately $10,000, which includes interest at 7.5%.

In 1993, THG entered into an agreement with a stockholder to terminate his
employment with THG. In conjunction with this termination, THG agreed to pay
$749,000 in sixty monthly payments based on prime plus 2%. This amount
represents the remainder of this liability.

Capital lease obligations mature from 1997 through 2001 and have interest rates
ranging from 9.0% to 12.2%. Equipment, including computer equipment, consists of
$2,116,000 and $2,776,000 of cost and $1,270,000 and $1,637,000 of accumulated
depreciation for assets held under capital leases at December 31, 1995 and 1996,
respectively. At December 31, 1996, the aggregate remaining lease payments were
$1,361,000 including interest of $187,000.

12.   COMMITMENTS AND CONTINGENCIES
      -----------------------------

The Company maintains insurance coverage against possible liabilities that may
be incurred in connection with the conduct of its worldwide business. While the
Company believes it operates safely and prudently, there can be no assurance
that all possible types of liabilities that may be incurred by the Company are
covered by its insurance or that the dollar amount of such liabilities will not
exceed the Company's policy limits.

In the normal course of business, the Company is a party to various claims and
legal proceedings. Although the ultimate outcome of these matters is presently
not determinable, management of the Company, after consultation with legal
counsel, does not believe that the resolution of these matters will have a
material effect upon the Company's financial condition or results of operations.
However, because this is a forward-looking statement which contains risks and
uncertainties, the actual resolution may be material if, for example, facts are
uncovered which are not currently known by the Company or the Company is subject
to an unforeseen, unfavorable ruling by a court.

13.   SUBORDINATED NOTES AND SERIES A PREFERRED STOCK
      -----------------------------------------------

On February 23, 1993, the Company sold subordinated notes and warrants for
$3,535,000. The subordinated notes had a face value of $3,535,000 and were due
on January 31, 2003. Interest on the notes was 8% per year and was payable as
follows: 35% of the interest payable in June and December of each year, with the
remaining 65% due on January 31, 2003. The deferred portion of the interest
would bear interest at the same rate as the notes and could be prepaid by the
Company. The notes had certain voting rights and certain covenants including
antidilution provisions and other covenants, as defined. The noteholders were
entitled to elect one member to the Company's Board of Directors.

The subordinated notes were recorded at a discounted value of $3,494,000 to
record the fair value of warrants issued. Upon the closing of the Merger (see
Note 6), the noteholders surrendered the subordinated notes in connection with
the exercise of the warrants and terminated all agreements with the Company
except for an agreement for certain registration rights. In addition, upon the
closing of the Merger, warrants to purchase 684,505 shares of common stock at
$2.58 per share were issued to the noteholders in connection with their approval
of the Merger.

In December 1996, warrants underlying 297,223 shares of common stock were
exercised. In January 1997, the remaining 387,282 warrants were exercised.

14.   STOCK OPTIONS AND WARRANTS
      --------------------------

In conjunction with the Merger (see Note 6), the Company's stockholders approved
the 1994 Incentive Stock Plan (the "1994 Plan") which authorizes the granting of
incentive and nonqualified stock options, stock appreciation rights and stock
awards (together the "Incentives") to officers, key employees, directors and
consultants. All previously issued Bio-Pharm options were converted into the
1994 Plan. A maximum of 2,250,000 shares of common stock are issuable pursuant
to the 1994 Plan. The two predecessor plans of Affinity, described below, have
survived the Merger.

In January 1992, the Company established its 1992 Incentive Stock Plan (the
"1992 Plan"), which authorizes the granting of Incentives to officers, key
employees, directors and consultants. A maximum of 725,000 shares of common
stock are issuable pursuant to the 1992 Plan. On June 16, 1993, the stockholders
approved the Company's 1993 Incentive Stock Plan (the "1993 Plan"). The 1993
Plan authorizes the granting of Incentives to officers, key employees, directors
and consultants. A maximum of 750,000 shares of common stock are issuable
pursuant to the 1993 Plan.

The 1992, 1993 and 1994 Plans (collectively referred to as the "Plans") are
administered by a committee of the Board of Directors, the members of which are
ineligible to participate. The committee determines who will receive Incentives,
the types of Incentives to be granted and the terms and conditions of such
Incentives. To date, the Company has only granted nonqualified stock options,
the exercise price of which was determined by the committee at the time the
options were granted. Options issued under the Plans generally vest over five
years. All options expire no later than ten years from the date of the grant.

During 1995, the Company's stockholders approved the 1994 Non-employee Director
Stock Option Plan (the "Directors' Plan") which authorizes the granting of
nonqualified stock options to non-employee members of the Board of Directors. A
maximum of 300,000 shares of common stock are issuable pursuant to the
Directors' Plan. Options are granted to eligible Board members each year based
on a formula, as defined in the Directors' Plan.

In addition to options issued under the Plans and the Directors' Plan, certain
other options have been issued. As of December 31, 1995 all options issued not
pursuant to one of the plans indicated above have been exercised.

In October 1995, the Financial Accounting Standards Board adopted Statement of
Financial Accounting Standards No. 123, "Accounting for Stock-Based
Compensation" (SFAS 123). Effective January 1, 1995, the Company has elected to
adopt the disclosure requirement of this pronouncement. Had compensation cost
for the Company's stock option plans been determined based upon the fair value
at the grant date for awards under SFAS 123, the Company's net loss and net loss
per share for 1995 would have been $4,835,000 and $0.34, respectively, while net
income and net income per share for 1996 would have been $522,000 and $0.02,
respectively. Because the SFAS 123 method of accounting has not been applied to
options granted prior to January 1, 1995, the resulting pro forma compensation
cost, and thus pro forma net income (loss), may not be representative of that to
be expected in future years. The weighted average fair value at the date of
grant for options granted during 1995 and 1996 is estimated as $1.51 and $3.09
per share, respectively, using the Black-Scholes option-pricing model. The
assumptions used in the Black-Scholes model are as follows: dividend yield of
0%, expected volatility of 40%, risk-free interest rate of 6.46% in 1995 and
6.05% in 1996, and an expected option life of 6 years.

15.   LEASES
      ------

The Company entered into a lease in 1989 for its corporate headquarters office
space, which included reduced rental payments in the initial years of the lease.
The accompanying financial statements reflect total rent expense on a
straight-line basis over the term of the lease. The Company also has leases for
its other 16 primary office and laboratory locations. Rent expense for all
operating leases was $1,911,000, $2,732,000 and $3,182,00 in 1994, 1995 and 1996
respectively. The future minimum lease payments as of December 31, 1996, under
the noncancelable operating leases for equipment and office space are as
follows:
<TABLE>

             2002 and thereafter                            9,579,000
</TABLE> 

Included in the future minimum lease payments above is a fifteen year lease for
new office, laboratory and manufacturing facilities for the Pharmaceutics
Services Division. This lease is for 124,000 square feet of space. The
Pharmaceutics Services Division expects to phase in operations in this new
facility over the next several years, beginning with 40,000 square feet in 1997.

As of December 31, 1996, the Company had issued a bank letter of credit for
$300,000 to the landlord of its headquarters facility in lieu of a cash security
deposit.



16.   EMPLOYEE RETIREMENT PLANS
      -------------------------

In January, 1991, the Company established a 401(k) Retirement Plan for all
qualified U. S. employees. The employer contributions credited to the plan were
charged to expense and were $53,000, $91,000 and $187,000 in 1994, 1995, and
1996, respectively. The plan also provides for discretionary contributions as
approved by the Board of Directors. There were no discretionary contributions in
1994, 1995, or 1996.

In the United Kingdom, the Company operates defined contribution pension plans.
The assets of the plans are held separately from those of the Company in eight
independently administered funds. The employer contributions credited to the
plan were charged to expense and were $197,000, $132,000 and $183,000 in 1994,
1995 and 1996 respectively.

Prior to acquisition, both RBI and THG maintained their own 401(k) Retirement
Plans for qualified employees. These plans have been merged into the IBAH plan
effective January 1, 1997. Since their acquisitions, $34,000 of employer match
contributions have been made to these Plans.

17.   RELATED PARTY TRANSACTIONS
      --------------------------
  
At December 31, 1996, the Company had two mortgage receivables totaling $150,000
due from two former stockholders of THG (see Note 6). These mortgages are
secured by a condominium and a personal residence and bear interest at 8% and
5.78%. Payments are in monthly installments of $765 and $773. These receivables
are included in other assets on the accompanying balance sheet.

On January 19, 1996, the Company entered into a one-year agreement with Vector
Securities International, Inc. ("Vector Securities"), an affiliate of Vector
Later-Stage Equity Fund, L.P., a fund managed by Sandra Panem, a member of the
Company's Board of Directors. Pursuant to the agreement, Vector Securities will
provide strategic advisory services to the Company in return for standard
up-front fees and fees related to any specific transactions consummated by the
Company.

In January, 1992, Affinity entered into a five year contract for management
advisory services with an entity controlled by the Chairman of the Company's
Board. This contract provides for quarterly payments. Since the Merger, the
Company incurred $74,000 under this contract in 1994, $87,000 in 1995 and
$122,000 in 1996. This contract was terminated effective December 31, 1996.

At December 31, 1994, the Company had a $75,000 demand note from an employee.
The demand note is secured by 25,000 shares of the Company's common stock and
bears interest at prime, which was 8.5% at December 31, 1994. Interest income on
this note for the year ended December 31, 1994, was $6,000. The note was repaid
in 1995.

                       CERTIFICATE OF AMENDMENT TO THE 
                         CERTIFICATE OF INCORPORATION 
                                      OF 
                                  IBAH, INC.


     IBAH, Inc. (the "Corporation"), a corporation organized under and by virtue
of the General Corporation Law of the State of Delaware (the "Delaware General
Corporation Law"), for the purpose of amending its Certificate of Incorporation,
as amended (the "Certificate of Incorporation"), pursuant to Section 242(b) of
the Delaware General Corporation Law,

     DOES HEREBY CERTIFY:

     FIRST:    That the Board of Directors of the Corporation duly adopted
resolutions setting forth a proposed amendment of the Certificate of
Incorporation of the Corporation, as amended, declaring said amendment to be
advisable and directing that said amendment be submitted to the stockholders of
the Corporation for consideration and approval thereof at the annual meeting of
stockholders. The resolutions setting forth the proposed amendment are as
follows:

     RESOLVED, that, pursuant to Section 242 of the General Corporation Law of
the State of Delaware, Article TENTH be added to the Certificate of
Incorporation of this Corporation as follows:

     A.  Election and Terms of Directors; Board Action.  The directors, other
         ----------------------------------------------  
than those who may be elected pursuant to this Certificate of Incorporation by
the holders of any series of preferred stock voting separately as a single
class, shall be divided, with respect to the time for which they severally hold
office, into three classes with the term of office of the first class to expire
at the first annual meeting of stockholders following the adoption of this
Article TENTH, the term of office of the second class to expire at the second
annual meeting of stockholders following the adoption of this Article TENTH and
the term of office of the third class to expire at the third annual meeting of
stockholders following the adoption of this Article TENTH, with each such
director to hold office until his or her successor shall have been duly elected
and qualified. At each annual meeting of stockholders, commencing with the first
annual meeting of stockholders following the adoption of this Article TENTH, (i)
directors elected to succeed those directors whose terms then expire shall be
elected for a term of office to expire at the third succeeding annual meeting of
stockholders after their election and until his or her successor shall have been
duly elected and qualified, and (ii) if authorized by a resolution of the Board
of Directors and expect as otherwise provided in this Certificate of
Incorporation with respect to the rights of the holders of any series of
preferred stock to elect directors, directors may be elected to fill any vacancy
on the Board of Directors, regardless of how such vacancy shall have been
created. Any director who may be elected pursuant to this Certificate of
Incorporation by the holders of any series of preferred stock voting separately
as a single class, shall, at each annual meeting of stockholders, be elected for
a term of office to expire at the next annual meeting of stockholders and until
his or her successor shall have been duly elected and qualified or until he or
she resigns or is removed from office by the holders of such series of preferred
stock; provided, however, that the term of office of any such director shall
expire at the next annual meeting that follows the date as of which any such
preferred stock shall no longer be outstanding.

     B.  Newly Created Directorships and Vacancies.   Subject to applicable law
         ------------------------------------------
and to the rights of the holders of any series of preferred stock to elect
directors as provided in this Certificate of Incorporation, and unless the Board
of Directors otherwise determines, newly created directorships resulting from
any increase in the authorized number of directors or any vacancies on the Board
of Directors resulting from death, resignation, retirement, disqualification,
removal from office or other cause shall be filled only by a majority vote of
the directors then in office, though less than a quorum, and directors so chosen
shall hold office for a term expiring at the annual meeting of stockholders at
which the term of office of the class to which they have been elected expires
and until such director's successor shall have been duly elected and qualified.
If there are no directors in office, subject to the rights of the holders of any
series of preferred stock to elect directors as provided in this Certificate of
Incorporation, then an election of directors may be held in the manner provided
by statute. No decrease in the number of authorized directors constituting the
entire Board of Directors shall shorten the term of any incumbent 
<PAGE>
 
director. If a director elected by the holders of any series of preferred stock
entitled to vote separately as a single class is removed by such holders, and if
the holders of such series of preferred stock for any reason fail to elect
anyone to fill any such directorship, such position shall remain vacant until
such time as the holders of such series of preferred stock elect a director to
fill such position and shall not be filled by resolution or vote of the
Corporation's Board of Directors or the Corporation's other stockholders.

     C.  Removal.  Any director classified pursuant to Section A of this Article
         --------  
TENTH, or all such directors, may be removed from office at any time, but only
for cause and only by the affirmative vote of the holders of at least 75 percent
of the voting power of all of the then outstanding shares entitled to vote
generally in the election of directors, voting together as a single class. Any
director who may be elected pursuant to this Certificate of Incorporation by the
holders of any series of preferred stock voting separately as a single class may
be removed from office at any time, with or without cause, by the affirmative
vote of the holders of a majority of the shares of such series of preferred
stock voting separately as a single class.

     D.  Amendment, Repeal or Alteration.     Except as otherwise provided in
         --------------------------------
this Certificate of Incorporation with respect to the rights of the holders of
any series of preferred stock to amend, repeal, alter or waive any provisions of
this Certificate of Incorporation affecting such series of preferred stock,
notwithstanding any other provision of this Certificate of Incorporation or any
provision of law which might otherwise permit a lesser vote or no vote, but in
addition to any affirmative vote of the holders of a particular class or series
of the capital stock required by law or this Certificate of Incorporation, the
affirmative vote of the holders of at least 75 percent of the voting power of
all of the then outstanding shares entitled to vote generally in the election of
directors, voting together as a single class, shall be required to alter, amend
or repeal this Article TENTH.

              FURTHER RESOLVED, that the foregoing Amendment to the Certificate
of Incorporation of this Corporation shall be effective upon the effective date
of the filing of a Certificate of Amendment to the Certificate of Incorporation
of this Corporation, setting forth the foregoing Amendment, with the Secretary
of State of the State of Delaware.

     SECOND:   That thereafter, pursuant to resolution of the Board of
Directors, said amendment was submitted for the approval of the stockholders of
the Corporation at the annual meeting of stockholders of the Corporation held on
June 19, 1996.

     THIRD:    That said amendment was duly adopted in accordance with the
provisions of Section 242 of the Delaware General Corporation Law.

     FOURTH:   That the capital of the Corporation was not reduced under or by
reason of said amendment.

     IN WITNESS WHEREOF, this Certificate of Amendment has been duly executed by
the undersigned officers this 26th day of June, 1996.

     Section 2.3. Special Meetings.  Special meetings of the stockholders, for
                  ----------------

Board, the President or shall be called by the President or Secretary at the
request in writing of a majority of the Board of Directors, or at the request in

Corporation issued and Outstanding and entitled to vote.  Such request shall
state the purpose or purposes of the proposed meeting.  Business transacted at
any special meeting of stockholders shall be limited to the purposes stated in

permitted to take any action at a meeting, a written notice of the meeting

at least ten days before every meeting of stockholders, a complete list of the
stockholders entitled to vote at the meeting, 
<PAGE>
 
arranged in alphabetical order, and showing the address of each stockholder and
the number of shares registered in the name of each stockholder. Such list shall
be open to the examination of any stockholder, for any purpose germane to the
meeting, during ordinary business hours, for a period of at least ten days prior
to the meeting, either at a place within the city where the meeting is to be
held, which place shall be specified in the notice of the meeting, or, if not so
specified, at the place where the meeting is to be held. The list shall also be
produced and kept at the time and place of the meeting during the whole time
thereof, and may be inspected by any stockholder who is present.

     Section 2.6. Quorum.  At each meeting of stockholders the presence in
                  ------                                                  
person or by proxy of the holders of shares of stock having a majority of the
votes which could be cast by the holders of all outstanding shares of stock
entitled to vote at the meeting, shall be necessary and sufficient to constitute
a quorum for the transaction of business except as otherwise provided by statute
or by the Certificate of Incorporation.  In the absence of a quorum, the
stockholders so present may, by majority vote, adjourn the meeting from time to
time, without notice other than announcement at the meeting, until a quorum
shall be present or represented.  At such adjourned meeting at which a quorum
shall be present or represented any business may be transacted which might have
been transacted at the original meeting. If the adjournment is for more than
thirty days or if after the adjournment a new record date is fixed for the
adjourned meeting, a notice of the adjourned meeting shall be given to each
stockholder of record entitled to vote at the meeting.  Shares of its own stock
belonging to the Corporation or to another corporation, if a majority of the
shares entitled to vote in the election of directors of such other corporation
is held, directly or indirectly, by the Corporation, shall neither be entitled
to vote nor be counted for quorum purposes; provided, however, that the
foregoing shall not limit the right of the Corporation to vote stock, including,
but not limited, to its own stock, held by it in a fiduciary capacity.

     Section 2.7. Organization.  Meetings of stockholders shall be presided over
                  ------------                                                  
by the Chairman of the Board, if any, or in his or her absence by the Vice
Chairman of the Board, if any, or in his or her absence by the President, or in
his or her absence by a Vice President, or in the absence of the foregoing
persons by a chairman designated by the Board of Directors.  The Secretary shall
act as secretary of the meeting, but in his or her absence the chairman of the
meeting may appoint any person to act as secretary of the meeting.

     Section 2.8. Voting: Proxies.  Except as otherwise provided by this
                  ---------------                                       
Certificate of Incorporation, each stockholder entitled to vote at any meeting
of stockholders shall be entitled to one vote for each share of stock held by
him or her which has voting power upon the matter in question.  Each stockholder
entitled to vote at a meeting of stockholders may authorize another person or
persons to act for him or her by proxy, but no such proxy shall be voted or
acted upon after three years from its date, unless the proxy provides for a
longer period.  A duly executed proxy shall be irrevocable if it states that it
is irrevocable and if, and only as long as, it is coupled with an interest
sufficient in law to support an irrevocable power.  A stockholder may revoke any
proxy which is not irrevocable by attending the meeting and voting in person or
by filing an instrument in writing revoking the proxy or another duly executed
proxy bearing a later date with the Secretary of the corporation.  Voting at
meetings of stockholders need not be by written ballot and need not be conducted
by inspectors of election unless so determined by the holders of shares of stock
having a majority of the votes which could be cast by the holders of all
outstanding shares of stock entitled to vote thereon which are present in person
or by proxy at such meeting.  At all meetings of stockholders for the election
of directors a plurality of the votes cast shall be sufficient to elect.  All
other elections and questions shall, unless otherwise provided by law, the
Certificate of Incorporation or these By-laws, be decided by the vote of the
holders of shares of stock having a majority of the votes which could be cast by
the holders of all shares of stock entitled to vote thereon which are present in
person or represented by proxy at the meeting.

     Section 2.9. Action without Meeting. Unless otherwise restricted by the
                  ----------------------                                    
Certificate of Incorporation, any action required or permitted to be taken at
any annual or special meeting of stockholders may be taken without a meeting,
without prior notice and without a vote, if a consent in writing, setting forth
the action so taken, shall be signed by the holders of outstanding stock having
not less than the minimum number of votes that would be necessary to authorize
or take such action at a meeting at which all shares entitled to vote thereon
were present and voted.  Prompt notice of the taking of the corporate action
without a meeting by less than unanimous written consent shall be given to those
<PAGE>
 
stockholders who have not consented in writing.

     Section 2.10.  Fixing Date for Determination of Stockholders of Record.  In
                    -------------------------------------------------------     
order that the Corporation may determine the stockholders entitled to notice of
or to vote at any meeting of stockholders or any adjournment thereof, or to
express consent to corporate action in writing without a meeting, or entitled to
receive payment of any dividend or other distribution or allotment of any
rights, or entitled to exercise any rights in respect of any change, conversion
or exchange of stock or for the purpose of any other lawful action, the Board of
Directors may fix a record date, which record date shall not precede the date
upon which the resolution fixing the record date is adopted by the Board of
Directors and which record date: (1) in the case of determination of
stockholders entitled to vote at any meeting of stockholders or adjournment
thereof, shall, unless otherwise required by law, not be more than sixty nor
less than ten days before the date of such meeting; (2) in the case of
determination of stockholders entitled to express consent to corporate action in
writing without a meeting, shall not be more than ten days from the date upon
which the resolution fixing the record date is adopted by the Board of
Directors; and (3) in the case of any other action, shall not be more than sixty
days prior to such other action.  If no record date is fixed: (1) the record
date for determining stockholders entitled to notice of or to vote at a meeting
of stockholders shall be at the close of business on the day next preceding the

                               Board of Directors

     Section 3.1. Number; Qualifications.  The Board of Directors shall consist
                  ----------------------                                       
of not less than five nor more than eleven members, as shall be determined from
time to time by resolution of the Board, subject to the power of the
stockholders to change such action.  At least three of the directors shall be
"Independent Directors".  For purposes of these By-laws "Independent Director"
shall mean a person, other than an officer or employee of the Corporation or its
subsidiaries or any other individual who has a relationship with the Corporation
which, in the opinion of the Board of Directors, would interfere with the
exercise of independent judgment in carrying out the responsibilities of a
director.  The directors need not be stockholders.

     Section 3.2.  Election and Terms of Directors; Board Action.   The
                   ---------------------------------------------       
directors, other than those who may be elected pursuant to the Certificate of
Incorporation by the holders of any series of preferred stock voting separately
as a single class, shall be divided, with respect to the time for which they
severally hold office, into three classes with the term of office of the first
class to expire at the 1997 annual meeting of stockholders, the term of office
of the second class to expire at the 1998 annual meeting of stockholders and the
term of office of the third class to expire at the 1999 annual meeting of
stockholders, with each such director to hold office until his or her successor
shall have been duly elected and qualified.  At each annual meeting of
stockholders, commencing with the 1997 annual meeting of stockholders, (i)
directors elected to succeed those directors whose terms then expire shall be
elected for a term of office to expire at the third succeeding annual meeting of
stockholders after their election and until his or her successor shall have been
duly elected and qualified, and (ii) if authorized by a resolution of the Board
of Directors and except as otherwise provided in the Certificate of
Incorporation with respect to the rights of the holders of any series of
preferred stock to elect directors, directors may be elected to fill any vacancy
on the Board of Directors, regardless of how such vacancy shall have been
created.  Any director who may be elected pursuant to the Certificate of
Incorporation by the holders of any series of preferred stock voting separately
as a single class, shall, at each annual meeting of stockholders, be elected for
a term of office to expire at the next annual meeting of stockholders and until
his or her successor shall have been duly elected and qualified or until he or
she resigns or is removed from office by the holders of such series of preferred
stock; provided, however, that the term of office of any such director shall
expire at the next annual meeting that follows the date as of which any such
preferred stock shall no longer be outstanding.

     Section 3.3.  Newly Created Directorships and Vacancies; Resignation;
                   -------------------------------------------------------
Removal.  Subject to applicable law and to the rights of the holders of any
- -------                                                                    
series of preferred stock to elect directors as provided in the Certificate of
Incorporation, and unless the Board of Directors otherwise determines, newly
created directorships resulting from any increase in the authorized number of
directors or any vacancies on the Board of Directors resulting from death,
resignation, retirement, disqualification, removal from office or other cause
shall be filled only by a majority vote of the directors then in office, though
less than a quorum, and directors so chosen shall hold office for a term
expiring at the annual meeting of stockholders at which the term of office of
the class to which they have been elected expires and until such director's
successor shall have been duly elected and qualified. If there are no directors
in office, subject to the rights of the holders of any series of preferred stock
to elect directors as provided in the Certificate of Incorporation, then an
election of directors may be held in the manner provided by statute. If, at the
time of filling any newly created directorship or any vacancy, the directors
then in office shall constitute less than a majority of the whole Board (as
constituted immediately prior to any such increase), the Court of Chancery may,
upon application of any stockholder or stockholders holding at least ten percent
of the total number of shares at the time outstanding having the right to vote
for such directors, summarily order an election to fill any such newly created
directorships or vacancies, or to replace the directors chosen by the directors
then in office. No decrease in the number of authorized directors constituting
the entire Board of Directors shall shorten the term of any incumbent director.
If a director elected by the holders of any series of preferred stock entitled
to vote separately as a single class is removed by such holders, and if the
holders of such series of preferred stock for any reason fail to elect anyone to
fill any such directorship, such position shall remain vacant until such time as
the holders of such series of preferred stock elect a director to fill such
position and shall not be filled by resolution or
<PAGE>
 
vote of the corporation's Board of Directors or the corporation's other
stockholders. Any director may resign at any time upon written notice to the
corporation. Any director classified pursuant to Section 3.2, or all such
directors, may be removed from office at any time, but only for cause and only
by the affirmative vote of the holders of at least 75 percent of the voting
power of all of the then outstanding shares entitled to vote generally in the
election of directors, voting together as a single class. Any director who may
be elected pursuant to the Certificate of Incorporation by the holders of any
series of preferred stock voting separately as a single class may be removed
from office at any time, with or without cause, by the affirmative vote of the
holders of a majority of the shares of such series of preferred stock voting
separately as a single class.

                             EMPLOYMENT AGREEMENT
                             --------------------

     This Employment Agreement (this "Agreement") is made as of the 1st day of 
October, 1996 between IBAH, Inc., Delaware corporation ("IBAH"), and Sherrin H. 
Baky (the "Employee").

                                  Background
                                  ----------

     IBAH desires to employ the Employee, and the Employee desires to become an 
employee of IBAH, upon the terms and conditions hereinafter set forth.

     This Agreement is one of the Employment Agreements that is referred to in
the Agreement and Plan of Merger, by and among IBAH, IBAH Acquisition Company,
HBG, Inc. and the stockholders of HBG, Inc. (the "Merger Agreement").

                                  Witnesseth:
                                  ----------

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

1.   Employment.
     ----------

     IBAH hereby employs the Employee as Executive Vice President of The 
Hardardt Group, Inc., a wholly-owned subsidiary of IBAH, and Executive Vice 
President of IBAH, and the Employee hereby accepts such employment. During the 
term of employment under this Agreement (the "Employment Term"), the Employee 
shall continue to perform duties similar to those she has heretofore 
performed as Executive Vice President of HGB, Inc., and such other similar 
duties as are requested from time to time by the Chief Executive Officer of IBAH
and such other person(s) as may be mutually agreed upon by the Chief Executive 
Officer and the Employee.

2.   Performance.
     -----------

     During the Employment Term, the Employee shall devote her entire business 
efforts to the performance of her duties hereunder.

3.   Term.
     ----

     The Employment Term shall be for the period commencing on the date of this
Agreement and ending on the two year anniversary of this Agreement, unless 
terminated earlier pursuant to the terms of Section 5 or Section 6 of this 
Agreement.
<PAGE>
 
4.   Compensation for Employment.
     ---------------------------

     (a)  The basic annual compensation of the Employee for her employment 
services to IBAH and to all of its affiliated companies during the Employment 
Term shall be $175,000 (the "Salary"), which IBAH shall pay to the Employee in 
accordance with its normal payroll policy. IBAH may adjust the salary upward on
an annual basis as the Board may determine, but the Salary shall not be
decreased.

     (b)  During the Employment Term, IBAH shall also provide the Employee with 
those fringe benefits generally afforded to other executives of IBAH of 
comparable levels of compensation and responsibility, including, without 
limitation, option and bonus plans (at Level Grade 0 under the current IBAH 
plans), health insurance benefits, disability benefits, life insurance benefits 
and retirement benefits (the "Fringe Benefits") in accordance with Section 5.5 
of the Merger Agreement. IBAH shall also reimburse the Employee for any 
reasonable business expenses incurred on IBAH's behalf in connection with the 
performance of her services during the Employment Term, provided, however, that 
such benefits are being offered by IBAH to its other executives of comparable 
levels of compensation and responsibility.

     (c)  The Employee shall be entitled to four (4) weeks of paid vacation each
year, plus a vacation bonus of two (2) weeks of paid vacation each year.

5.   Termination Without Compensation.
     --------------------------------

     (a)  Expiration of Employment Term.  Upon expiration of the Employment 
          -----------------------------
Term, IBAH shall not have further liability or obligation to the Employee 
hereunder except for any unpaid Salary and Fringe Benefits accrued to the date 
of expiration.

     (b)  Partial or Total Disability.  If the Employee is unable to perform her
          ---------------------------
duties and responsibilities hereunder to the full extent required hereunder by 
reason of illness, injury or incapacity for six months (during which time she
shall continue to be compensated hereunder), IBAH may terminate the Employment
Term, and IBAH shall not have any further liability or obligation to the
Employee hereunder except for any unpaid Salary and Fringe Benefits accrued to
the date of termination, and IBAH shall, through the two-year anniversary of
this Agreement, continue to provide to the Employee the same Fringe Benefits as
were provided prior to her termination to the maximum extent permissible under
the terms of the plans and policies governing those Fringe Benefits. In the
event of any dispute under this Section 6(b), the Employee shall submit to a
physical examination by a licensed physician mutually satisfactory to IBAH and
the Employee, the cost of such examination to be paid by IBAH, and the
determination of such physician shall be determinative. If, after termination
due to disability as provided herein, the Employee obtains, at her sole expense,
medical certification from a licensed physician reasonably satisfactory to IBAH
that such disability has ended, IBAH shall offer to employ the Employee pursuant
to the terms of this Agreement for the remainder of the Employment Term in
effect at the time of termination, except that IBAH shall not be required to
reemploy the Employee at the same officer position if IBAH shall have elected
another person

                                      -2-
<PAGE>
 
to such position during the period of the Employee's disability and such other 
person continues in such position at the time of the Employee's return to 
employment.

     (c)  Death.  If the Employee dies, this Employment Agreement (except for 
          -----
the provisions of Sections 7, 8, 9, 10 and 11 hereof) shall terminate, and 
thereafter IBAH shall not have any further liability or obligation to the 
Employee, her executors, administrators, heirs, assigns or any other person 
claiming under or through her except for unpaid Salary and Fringe Benefits 
accrued to the date of her death.

     (d)  Cause.  IBAH may terminate the Employment Term for "cause" (as defined
          -----
below), and after the termination date, IBAH shall not have any further 
liability or obligation to the Employee hereunder except for any unpaid Salary 
and Fringe Benefits accrued to the date of termination and any other continuing 
obligations arising out of this Agreement or other Agreements between IBAH and 
the Employee. For purposes of this Agreement, "cause" shall mean breach of any 
of the material terms or provisions of this Agreement other than by reason of 
illness, injury or incapacity; habitual material neglect of her duties and 
responsibilities hereunder; willful misconduct in performing her duties and 
responsibilities hereunder; conviction of a felony or other crime involving 
moral turpitude; or misappropriation of IBAH funds. Any breach of a material 
term of this Agreement, habitual neglect of her duties, or willful misconduct 
shall constitute "cause" only if the action or omission at issue shall be 
continuing 30 days after IBAH gives the Employee written notice of the 
termination date and the reasons for termination, and an opportunity to cure 
such breach, neglect or misconduct. The Employee's conviction of a felony or 
other crime involving moral turpitude or misappropriation of IBAH funds shall 
constitute "cause" if IBAH gives the Employee ten days' written notice of 
termination date.

6.   Termination With Compensation.
     -----------------------------

     (a)  By IBAH Without Cause.  IBAH shall have the right to terminate the 
          ---------------------
Employment Term without cause at any time by giving the Employee 30 days' 
written notice of the termination date. Under such circumstances, IBAH shall 
provide the Employee with the Termination Compensation specified in Section 
6(c).

     (b)  By Employee.  The Employee shall have the right to terminate the 
          -----------
Employment Term by giving 12 months' written notice of the termination date. 
Under such circumstances, IBAH shall provide the Employee with the Termination 
Compensation specified in Section 6(c)

     (c)  Termination Compensation.  The "Termination Compensation" shall 
          ------------------------
consist of the payment of the Employee's Salary under Section 4(a), and the 
continuation of the Fringe Benefits under Section 4(b) to the maximum extent 
permissible under the terms of the plans and policies governing these Fringe 
Benefits, at the level in effect at the date of termination, for any remaining 
part of the Employment Term in effect at the date of termination. The Employee 
shall not be entitled to any Termination Compensation under this Section 6 
unless the Employee executes and delivers to IBAH after a notice of termination 
a release in a form satisfactory to IBAH in its sole discretion by which the 
Employee releases IBAH from any obligations and 

                                      -3-
<PAGE>
 
liabilities of any type whatsoever that arise out of this Agreement or her 
employment by IBAH, except for IBAH's obligation to provide the Salary and 
Fringe Benefits specified in this Section 6 and any other continuing obligations
arising out of this Agreement or other agreements between IBAH and the Employee.
The parties hereto acknowledge that the Salary to be provided under this Section
6 is to be provided in consideration for the above-specified release.

     (d)  Exclusivity.  Upon any termination by IBAH under Section 6(a) or 6(b),
          -----------
IBAH shall not have any obligation under this Agreement to the Employee, her
executors, administrators, heirs, assigns or any other person claiming under or 
through her other than to provide the Termination Compensation under the terms 
and conditions of Section 6(c) and to fulfill any other continuing obligations 
arising out of this Agreement.

7.   Agreement Not to Compete.
     ------------------------       

     (a)  During the Non-Competition Period (defined below), the Employee shall 
not, within the Restricted Area (defined below), directly or indirectly, in any 
capacity, render her services, engage or have a financial interest in, any 
business that is competitive with any business activities in which IBAH or any 
of its affiliates (each an "IBAH Party") shall have been engaged and in which 
the Employee was actively involved during her employment by IBAH. In addition, 
during the Non-Competition Period, the Employee shall not directly or indirectly
solicit any employees of IBAH or any of its affiliates to terminate their 
employment with the applicable IBAH Party. Any interest in a publicly-traded 
corporation, even though such corporation may be a competitor of IBAH, that the 
Employee holds as of the date hereof and has disclosed to IBAH, shall not be 
deemed to violate the restrictions contained in this Section 7(a). It shall 
also not be a violation of this Agreement for the Employee to invest in mutual 
funds or otherwise, so long as the Employee has no investment or trading 
discretion, even if such funds own securities of a competitor of IBAH.

     (b)  The "Non-Competition Period" means the Employment Term, any 
period of time during which the Employee receives Termination Compensation 
under Section 6(b) hereof, and for two years after the later of (i) the end of 
the Employment Term and (ii) the last date on which the Employee receives 
Termination Compensation, so long as IBAH continues to provide to the Employee 
health insurance benefits at the level in affect at the date of her termination 
for the duration of the Non-Competition Period.

     (c)  The "Restricted Area" means the entire world. The Employee hereby 
acknowledges that the scope of the Restricted Area is not unreasonable given the
nature of IBAH's business.

     (d)  If a court determines that the foregoing restrictions are too broad or
otherwise unreasonable under applicable law, including with respect to time or 
space, the court is hereby requested and authorized by the parties hereto to 
review the foregoing restriction to include the maximum restrictions allowable 
under applicable law.

                                      -4-
<PAGE>
 
     (e)  The terms of this Section 7 shall apply to the Employee and any 
person, partnership, association, corporation or other entity (a "Person") 
controlled by the Employee, including any relative of the Employee, to the same 
extent as if they were parties hereto, and the Employee shall take whatever
actions may be necessary to cause any such persons or entities to adhere to the
terms of this Section 7.

8.   Inventions, Designs and Product Developments.
     --------------------------------------------

     If at any time or times during the Employment Term, the Employee shall
(either alone or with others), make, conceive, create, discover, invent or
reduce to practice any invention, modification, discovery, design, development,
improvement, process, software program, work of authorship, documentation,
formula data, whether or not patentable or registrable under copyright,
trademark or similar statutes (including but not limited to the Semiconductor
Chip Protection Act) or subject to analogous protection) (herein called
"Developments") that (a) relates to the business of IBAH or any customer of or
supplier to IBAH or any of the products or services being developed,
manufactured or sold by IBAH or which may be used in relation therewith, (b)
results from tasks assigned to the Employee by IBAH or (c) results from the use
of premises or personal property (whether tangible or intangible) owned, leased
or contracted for by IBAH, such Developments and the benefits thereof are and
shall immediately become the sole and absolute property of IBAH and its assigns,
as "Work made for hire" or otherwise, and the Employee shall promptly disclose
to IBAH (or any persons designated by it) each such Development and, as may be
necessary to ensure IBAH's ownership of such Developments, the Employee hereby
assigns any rights (including, but not limited to, any copyrights and
trademarks) the Employee may have or acquire in the Development and benefits
and/or rights resulting therefrom to IBAH and its assigns without further
compensation and shall communicate, without cost or delay, and without
disclosing to others the same, all available information relating thereto (with
all necessary plans and models) to IBAH.

     The Employee will, during the Employment Term and at any time thereafter,
at the request and cost of IBAH, promptly sign, execute, make and do all such
deeds, documents, acts and things as IBAH and its duly authorized agents may
reasonably require:

               (a)  to apply for, obtain, register and vest in the name of IBAH
          alone (unless IBAH otherwise directs) letters patent, copyrights,
          trademarks or other analogous protection in any country throughout the
          world and when so obtained or vested to renew and restore the same;
          and

               (b)  to defend any judicial, opposition or other proceedings in
          respect of such applications and any judicial, opposition or other
          proceedings or petitions or applications for revocation of such
          letters patent, copyright, trademark or other analogous protection.

          In the event IBAH is unable, after reasonable effort, to secure the
     Employee's signature on any application for letters patent, copyright or
     trademark registration or other

                                      -5-
<PAGE>
 
documents regarding any legal protection relation to a Development, whether
because of the Employee's physical or mental incapacity or for any other reason
whatsoever, the Employee hereby irrevocably designates and appoints IBAH and its
duly authorized officers and agents as her agent and attorney-in-fact, to act
for and in her behalf and stead to execute and file any such application or
applications or other documents and to do all other lawfully permitted acts to
further the prosecution and issuance of letters patent, copyright or trademark
registrations or any other legal protection thereon with the same legal force
and effect as if executed by the Employee.

     The Employee represents that she has never been (i) debarred or convicted 
of a crime for which a person can be barred under 21 U.S.C. (S) 335a ("(S) 
335a") nor (ii) threatened to be debarred or indicated for a crime or otherwise 
engaged in conduct for which a person can be debarred under (S) 335a. The 
Employee will promptly notify IBAH in the event of any such debarment, 
conviction, threat or indictment occurring during the Employment Term.

9.   Confidential Information.
     ------------------------

     The Employee will not at any time, whether during or after the Employment 
Term, reveal to any person or entity any of the trade secrets or confidential 
information concerning the organization, business or finances of IBAH. 
Confidential information or trade secrets includes, but is not limited to, 
operating procedures, salary structure/compensation information, pricing 
strategies, investigator lists, budgets and other related data, computer 
software, databases and programming, data files, client lists and related 
information, financial information and projections, inventions, know-how, 
products, services, techniques and any other information which, if divulged to a
third party could have an adverse impact on IBAH, or on any third party to which
IBAH owes a confidentiality obligation, except as may be required in the 
ordinary course of performing the Employee's duties as an employee of IBAH.

     Further, the Employee acknowledges that client companies disclose 
confidential information to IBAH and that IBAH agrees, in writing, to maintain 
the confidentiality of this information. The Employee will not at any time, 
whether during or after the Employment Term, reveal to any person or entity any
trade secrets or confidential information concerning the organizations, business
or finances of any third party or client to which IBAH owes a confidentiality 
obligation.

10.  Remedies.
     --------

     The parties expressly acknowledge that a breach or evasion of any term of 
this Agreement by either party may cause immediate and irreparable harm to the 
other party and that the remedy at law for any breach will be inadequate. Upon 
any such breach or threatened breach, IBAH (or the applicable IBAH Party), or 
the Employee, as the case may be, shall be entitled as a matter of right to 
injunctive relief in any court of competent

                                      -6-
<PAGE>
 
jurisdiction, in equity or otherwise, and to enforce the specific performance of
the parties' obligations under these provisions without the necessity of proving
the actual damage or the inadequacy of a legal remedy. Subject to the remainder 
of this Section 10, the rights conferred upon the parties by the preceding 
sentence shall not be exclusive of, but shall be in addition to, any other 
rights or remedies which the parties may have at law, in equity or otherwise.

11.  Arbitration and Indemnification.
     -------------------------------
     
     (a)  Except as set forth in Section 10 above, any claim or controversy
arising out of or relating to this Agreement, or any breach thereof, or
otherwise relating to Employee's employment, compensation and benefits with
IBAH, or the termination thereof, excluding unemployment and workers'
compensation, shall be settled by arbitration in Philadelphia, Pennsylvania in
accordance with the Employment Dispute Resolution Rules of the American
Arbitration Association (AAA) then in effect to the extent provided herein, and
except as modified herein; provided, however, that the Employee and IBAH agree
that (1) the "panel" of arbitrators as used in the AAA Rules shall consist of a
single arbitrator; (2) the arbitrator shall be an attorney licensed to practice
law in Pennsylvania or New Jersey who has experience in employment matters; (3)
the arbitrator shall be prohibited from disregarding, adding to or modifying the
terms of this Agreement; (4) the arbitrator shall be required to follow
established principles of substantive law and the law governing burdens of
proof; (5) only legally protected rights may be enforced in arbitration; (6) the
arbitrator shall be without authority to award punitive or exemplary damages;
(7) any award must be supported by substantial record evidence and (8) any
demand for arbitration must be filed and served if at all, within 180 days of
the occurrence of the act or omission complained of. Any claim or controversy
not submitted to arbitration in accordance with this Section 11 shall be
considered waived and, thereafter, no arbitrator or tribunal or court shall have
the power to rule or make any award on any such claim or controversy. The award
rendered in any arbitration proceeding held under this Section 11 shall be final
and binding, and judgment upon the award may be entered in any court having
jurisdiction thereof, provided it conforms to established principles of law and
is supported by substantial record evidence.

     (b)  IBAH agrees to defend and indemnify the Employee and hold her harmless
from any and all claims, demands, suits, judgments, fines, penalties, and 
charges, including without limitation attorneys' fees in any way arising 
directly or indirectly out of her employment by IBAH or the performance of her 
obligations pursuant to this Agreement. The Employee and IBAH will cooperate in 
any defense, but IBAH will maintain complete control of the defense, including 
any decisions as to settlement.

                                      -7-

12.  Survival.
     --------

     Notwithstanding the termination of the Employment Term pursuant to Section 
5 or 6, the obligations of the Employee under Sections 7, 8, 9, 10 and 11 and

     WHEREAS, Consultant is now engaged in the business of providing such

     NOW, THEREFORE, for good and valuable consideration, AND INTENDING TO BE 
LEGALLY BOUND, Consultant and IBAH hereby agree as follows:

10.  DUTIES AND OBLIGATIONS OF CONSULTANT
     ------------------------------------

IBAH has engaged Consultant as an independent contractor to IBAH's business. 
Consultant shall be available to IBAH to perform such duties and 
responsibilities as shall be needed by the Chief Executive Officer of IBAH. It 
is contemplated by the parties that Consultant will provide services under this
Agreement on an "as needed" and "as available" basis. Consultant's duties may 
include, but shall not be limited to, advice and assistance in the areas of 
sales and marketing, industry trends and objectives, and regulatory.

2.0  COMPENSATION
     ------------

In consideration for the services to be provided under Paragraph 1.0 of this 
Agreement, IBAH agrees to pay Consultant a consulting fee (the "Fee"), payable 
in equal monthly installments during the term of this Agreement, of $375,000 and
to reimburse Consultant for all reasonable expenses incurred in the performance 
of his duties under this Agreement during the term. The Fee shall be paid in 
full regardless of any termination of this
<PAGE>
 
Agreement by the parties prior to September 14, 1997. This provision shall 
survive any termination of this Agreement.

3.0  TERM AND TERMINATION
     --------------------

The Employment Agreement is hereby terminated, effective September 15, 1996. The
effective date of this Consultant Agreement shall be September 15, 1996, and it 
shall continue for a term of one (1) year, until September 14, 1997, unless 
terminated by mutual written agreement of the parties before that date. 
Consultant may terminate this Agreement at any time by forty five (45) days 
written notice. Upon termination of this Agreement, Consultant will assemble and
turn over in an orderly fashion to authorized representatives of IBAH all 
documents, notes, computer programs and other material related to the services 
performed by Consultant.

by Vector Securities (or a subsequent vendor) shall continue throughout the term
of this Agreement plus a period of three months thereafter.

5.0  TAXES
     -----

It is understood that payments to Consultant for services rendered shall be made
in full as agreed, without any deductions for taxes of any kind whatsoever, in
conformity with Consultant's status as an independent contractor. It is
understood that any taxes that may be due and payable as a result of the
payments specified herein by IBAH to Consultant shall be entirely Consultant's
responsibility. It is understood that, as part of this Agreement, Consultant
undertakes to pay all taxes for which Consultant may be liable on such payments
when due.

6.0  CONFIDENTIALITY
     ---------------

All information, know-how, trade secrets and data (technical or non-technical)
transmitted or observed in conjunction with the performance of services under
this Agreement is deemed to be the confidential and proprietary information of
IBAH, its subsidiaries, subdivisions, affiliates, successors, assigns and/or
clients. Confidential information or trade secrets includes, but is not limited
to, operating procedures, salary structure/compensation information, pricing
strategies, investigator lists, budgets and other related data, computer
software, databases and programming, data files, client lists and related
information, financial information and projections, inventions, know-how,
products, services, techniques and any other information which, if divulged to a
third party could have an adverse impact on IBAH, or on any third party to which
IBAH owes a confidentiality obligation, except as may be required in the
ordinary course of performing the Consultant's duties. Consultant
<PAGE>
 
agrees that he will not at any time, whether during or after the termination of 
his status as a Consultant to IBAH, reveal to any person or entity any trade 
secrets or confidential information of IBAH.

Consultant understands that client companies disclose confidential information
to IBAH and that IBAH agrees, in writing, to maintain the confidentiality of 
this information. Accordingly, Consultant agrees that he will not at any time, 
whether during or after the termination of his status as a Consultant to IBAH, 
reveal to any person or entity any trade secrets or confidential information 
concerning any third party or client to which IBAH owes a confidentiality 
obligation.

     6.1  Confidential information does not include disclosed information that:
          (a) is or becomes part of the public domain through no fault of
          Consultant; (b) is disclosed to Consultant by a third party entitled
          to disclose it; or (c) is required by law to be disclosed.

     6.2  Consultant will only use the confidential information furnished by
          IBAH for the purpose of fulfilling his obligations under this
          Agreement. Upon the completion or earlier termination of this
          Agreement and at IBAH's request, Consultant will promptly return all
          written confidential information.

     6.3  Consultant will not use any such confidential information for his own
          benefit or for the benefit of any third party, and will not furnish to
          any third party any materials which incorporate any confidential
          information except as otherwise hereinabove provided. All obligations
          of confidentiality and non-disclosure set forth in this Agreement will
          survive, without limitation, the expiration or earlier termination of
          this Agreement.

     6.4  The obligations of confidentiality contained herein shall remain in 
          effect for five (5) years after the termination of this Agreement.

7.0  INTELLECTUAL PROPERTY
     ---------------------

If at any time or times during the term of this Agreement, Consultant shall 
(either alone or with others), make, conceive, create, discover, invent or 
reduce to practice any invention, modification, discovery, design, development, 
improvement, process, software program, work of authorship, documentation, 
formula, data, whether or not patentable or registrable under copyright, 
trademark or similar statutes (including but not limited to the Semiconductor 
Chip Protection Act) or subject to analogous protection (herein called 
"Developments") that:

          (a) relates to the business of IBAH or any client of or supplier of
          IBAH or any of the products or services being developed, manufactured
          or sold by IBAH or which may be used in relation therewith;

          (b) results from tasks assigned by IBAH; or,
<PAGE>
 
          (c) results from the use of premises or personal property (whether 
          tangible or intangible) owned, leased or contracted for by IBAH,

such Developments and the benefits thereof are and shall immediately become the 
sole and absolute property of IBAH and its assigns, as "work made for hire" or 
otherwise, and Consultant shall promptly disclose to IBAH (or any persons 
designated by it) each such Development and, as may be necessary to ensure 
IBAH's ownership of such Developments. Consultant hereby assigns any rights 
(including, but not limited to, any copyrights and trademarks) Consultant may 
have or acquire in the Developments and benefits and/or rights resulting 
therefrom to IBAH and its assigns without further compensation and shall 
communicate, without cost or delay, and without disclosing to others the same, 
all available information relating thereto (with all necessary plans and models)
to IBAH.

Consultant will, during the term of this Agreement and at any time thereafter, 
at the request and cost of IBAH, promptly sign, execute, make and do all such 
deeds, documents, acts and things as IBAH and its duly authorized agents may 
reasonably require:

     (a)  to apply for, obtain, register and vest in the name of IBAH alone
     (unless IBAH otherwise directs) letters patent, copyrights, trademarks or
     other analogous protection in any country throughout the world and when so
     obtained or vested to renew and restore the same; and

     (b)  to defend any judicial, opposition or other proceedings in respect of
     such applications and any judicial, opposition or other proceedings or
     petitions or applications for revocation of such letters patent, copyright,
     trademark or other analogous protection.

In the event that IBAH is unable, after reasonable effort, to secure 
Consultant's signature on any application for letters patent, copyright or 
trademark registration or other documents regarding any legal protection 
relating to a Development, whether because of Consultant's physical or mental 
incapacity or for any other reason whatsoever, Consultant hereby irrevocably 
designates and appoints IBAH and its duly authorized officers and agents as 
Consultant's agent and attorney-in-fact, to act for and in Consultant's behalf 
and stead to execute and file any such application or applications or other 
documents and to do all other lawfully permitted acts to further the prosecution
and issuance of letters patent, copyright or trademark registrations or any 
other legal protection thereon with the same legal force and effect as if 
executed by Consultant.

8.0  MODIFICATIONS TO THIS AGREEMENT
     -------------------------------

Modifications to this Agreement may only be made with the written agreement of 
both parties.
<PAGE>
 
9.0  CONSULTANT'S RELATIONSHIP WITH IBAH 
     -----------------------------------

Consultant's relationship with IBAH under this Agreement shall be that of an 
independent contractor, and nothing in the Agreement or the arrangement for 
which it is made shall constitute Consultant, or anyone furnished or used by 
Consultant in the performance of the services contemplated by this Agreement, as
an employee, joint venture partner or servant of IBAH.

Consultant will not participate in IBAH employee benefit plans nor receive any 
other compensation beyond that stated above. Consultant will not have power or 
authority to bind IBAH or to assume or create any obligation or responsibility, 
express or implied, on IBAH's part or in IBAH's name except as otherwise set 
forth in this Agreement and Consultant will not represent to any person or 
entity that Consultant has such power or authority.

10.0 INSURANCE
     ---------

Consultant understands that, since Consultant is an independent contractor, any 
personal injury or property damage suffered by Consultant in the course of 
carrying out any duties under this Agreement will be Consultant's sole 
responsibility. No insurance shall be obtained by IBAH concerning Consultant.

11.0 DEBARMENT
     ---------

Consultant represents that he has never been (i) debarred or convicted of a 
crime for which a person can be debarred under 21 U.S.C. (S) 335a ((S) "335a") 
or any other applicable law nor (ii) threatened to be debarred or indicted for a
crime or otherwise engaged in conduct for which a person can be debarred under 
(S) 335a. Consultant will promptly notify IBAH in the event of any such 
debarment, conviction, threat or indictment occurring during the term of this 
Agreement.

12.0 RELEASE
     -------

     12.1  In consideration for entering into this Agreement, consideration
           which Consultant hereby acknowledges, Consultant does hereby release
           and forever discharge IBAH and its present and former subsidiaries,
           affiliates, divisions, officers, directors, partners, principals,
           employees, agents, predecessors, assigns, servants, attorneys and
           insurers and each of them, and their respective successors, assigns,
           heirs, administrators and personal representatives of and from all
           actions and causes of action, suits, claims, debts and demands
           whatsoever in law or equity, which Consultant may have or claim to
           have against IBAH as a result of his employment or separation from
           employment, and does hereby covenant not to file a lawsuit to assert
           such claims. Consultant is not being asked to, and does not release,
           any claim which is nonwaivable as a matter of law.
<PAGE>
 
     12.2  By this release, Consultant knowingly and voluntarily waives any
           rights under any and all laws which provide legal restrictions on
           IBAH's right to terminate the Employment Agreement and/or the
           Employment relationship with Consultant, and under any federal,
           state, or other governmental statute, regulation, or ordinance,
           including, without limitation: (1) Title VII of the Civil Rights Act
           of 1964 and 1991; (2) the Age Discrimination in Employment Act of

           waives any claim against IBAH for personal injury or any other action
           against IBAH before any body (except for compensable injuries under
           the Pennsylvania Workers Compensation Act). Consultant is not waiving
           any rights or claims that may arise after the date this waiver is
           executed.

     12.3  Consultant forever waives and relinquishes all right to assert any 
           claim for recall, reemployment, or tenure with IBAH.

13.0 COVENANT NOT TO COMPETE
     -----------------------

Consultant and IBAH agree that paragraph 8 of the Employment Agreement (Covenant
Not to Compete) shall be made a part of and be incorporated into this Agreement.

14.0 WAIVER
     ------

The failure of either party to enforce any provision of this Agreement shall not
be construed as a waiver or limitation of that party's right to subsequently 
enforce and compel strict compliance with every provision of this Agreement.

deliver to Bank a Revolving Line of Credit Note in the face amount of Five
Million Dollars ($5,000,000.00), on terms and in form and substance satisfactory
to Bank, which shall evidence the aggregate of all Advances outstanding from
time to time pursuant to the Revolving Line of Credit Loan. Debtor hereby agrees
to pay to Bank the full amount of all Advances (including without limitation
overadvances), whether made, accepted or issued for the benefit of Debtor,
together with all 
<PAGE>
 
interest, fees and other charges which may accrue hereunder from time to time,
as provided in the Revolving Line of Credit Note. Debtor agrees and acknowledges
that its liability is a material and fundamental inducement to Bank's continuing
willingness to make Advances.

                     (b)       Advances may be available, subject to the
conditions of this Agreement, up to the amount of the Availability and subject
to the limitations of Sections 2.01 and 2.06, upon the request of any Designated
Officer of Debtor. If a request (which otherwise satisfies the conditions
hereof) is received by Bank by 2:00 p.m. on any business day, Bank will make an
Advance on the same business day; otherwise, the Advance will be made on the
next business day. Bank may make each Advance by crediting the amount of the
Advance to the Loan Account, or by depositing the amount of the Advance to the
demand deposit bank account of Debtor held at Bank according to instructions
given Bank by Debtor, or by otherwise disbursing to a third party upon terms and
conditions mutually agreeable to Bank and Debtor. No matter how or when an
Advance is made, or into what account or to or for the benefit of Debtor, or at
Debtor's request, Debtor shall immediately and automatically thereupon be
obligated to Bank on account of such Advance. Debtor may not disavow its
obligations hereunder, whether for Advances previously made or for Advances
which may be made after any request therefor and attempted disavowal.

           2.03      Interest and Payments; Charging Debtor's Accounts:
                     -------------------------------------------------

                     (a)       Interest shall be accrued, paid and calculated as
follows:

                               (1)        Interest will accrue and be payable on
principal amounts advanced by the Bank at the Loan Rate applicable to such Loan
(except that interest shall accrue at the Default Rate so long as an Event of
Default shall have occurred and be continuing uncured, and at all times after
acceleration and entry of any judgment), and shall be payable as accrued on the
last day of each calendar month, commencing immediately hereafter.

                               (2)        Interest shall be calculated on the
basis of a 360-day year, counting the actual number of days elapsed. All accrued
and then unpaid interest shall nevertheless be payable upon the Maturity Date.

                     (b)       If, at any time, the Rate shall be deemed by any
competent court of law, governmental agency or tribunal to exceed the maximum
rate of interest permitted by any applicable Laws, then, for such periods as the
Rate would be deemed excessive, its application shall be suspended and there
shall be charged instead the maximum rate of interest permissible under such
Laws. Any payments received by Bank during any such periods shall be
recalculated first as payments of interest at the maximum rate, and the balance
of each payment, if any, shall be deemed a payment (i) of any fees, charges,
reimbursements of expenses, or other items not treated as interest for purposes
of determining compliance with the maximum rate, and then (ii) of principal.

                     (c)       All sums payable to Bank hereunder including
repayments of Advances, and payments of interest, fees and other charges shall
be paid directly to Bank on or before the date due. Bank is authorized to charge
the Loan Account, or any deposit account of Debtor, for interest, fees or
charges as they come due, or at Bank's option make an Advance to pay any of the
same, provided Bank bills Debtor for interest, fees or charges, and such bill
remains unpaid five (5) business days after billing. In any case, Bank shall
send to Debtor statements of all amounts due hereunder.
<PAGE>
 
           (d)   Bank is authorized to charge the Loan Account, or any deposit
account of Debtor, at any time, without prior notice but with subsequent advice,
for any or all principal, interest, fees, charges and expense reimbursements
payable hereunder which is not otherwise paid when due.

           (e)   The Revolving Line of Credit is subject to an unused commitment
fee in the amount of .25% of the unused portion of the line on a quarterly
basis, as determined by the Bank's ledgers. The Bank will automatically charge
Debtor's checking account within seven days of sending a bill to Debtor.

     2.04  Prepayment; Facility Fees:

           (b)   So long as an Event of Default shall not have occurred and be
continuing uncured, Bank shall have the right to perform or have performed an
audit of Debtor once during any one (1) fiscal year period, and Debtor shall, on
demand, pay Bank for audits performed by Bank or its agents at a rate (if
performed by Bank's salaried personnel) to be determined, but in any event not
less than $750 per audit or the actual fees charged to Bank therefor (if
performed by others), plus Bank's out-of-pocket expenses, such rates and fees
subject to adjustment by Bank. After an Event of Default, Bank shall be
permitted to perform such audits at any time upon reasonable notice.

           (c)   Debtor shall be required to pay standard issuance charges for
any Letter of Credit and all other routine transaction charges in connection
therewith, including for amendments, if any, and reasonable fees and expenses
provided for in the International Facilities Agreement, all subject to periodic
adjustments by the Bank.

     2.05  Loan Account: Bank may, in its discretion, establish a Loan Account 
           ------------
and enter therein Advances, interest, fees, other charges, expenses and other
items properly chargeable to Debtor under this Agreement; all payments made by
Debtor on account of Indebtedness relating to any Loans; all proceeds of
collateral which are finally paid to Bank at its offices in cash or solvent
credits; and any other appropriate debits and credits. Notwithstanding the
foregoing, the Bank shall bill for the items referred to in the foregoing
sentence unless and until an Event of Default occurs. Subaccounts may be
established for each Loan established hereunder. The aggregate of the debit
balances in the Loan Account shall reflect Debtor's aggregate Indebtedness to
Bank from time to time by reason of the Loans or otherwise with respect hereto.

     2.06  Limits on Obligation of Bank to Make Advances Under Line of Credit
           ------------------------------------------------------------------

outstanding and all principal, interest, fees and other charges, under the
Revolving Line of Credit Loan at any time shall not exceed Five Million Dollars
($5,000,000.00) without Bank's consent; but if Bank consents, such consent shall
not bind Bank to continue to make any overadvance available thereafter. Debtor
agrees that it shall, immediately upon Bank's demand, pay or cause to be paid to
Bank the amount of any such excess, or, at Bank's option, deposit with Bank
liquid investment securities or money market instruments satisfactory to Bank
which have at deposit, and continue thereafter to have, a forced liquidation

enforcement, including attorney's fees and out-of-pocket expenses, shall be
borne solely by Debtor whether the same is incurred by Bank or Debtor.

           (c)   The following provisions shall apply upon the occurrence of an
Event of Default. Debtor shall turn over to Bank all checks, drafts, cash and
other remittances in payment or on account of payment of the Accounts, and
whenever expressly required by Bank, the cash proceeds of any returned goods
from the sale of which any Account arose. Debtor shall deposit such collections
and cash proceeds with Bank within two (2) banking days of the receipt thereof,
and in precisely the form received, except for the appropriate endorsements
where necessary to permit the collection of the items, which endorsement Debtor
hereby agrees to make. If Debtor receives any such cash or collections directly,
it will not commingle any such checks, drafts, cash and other remittances
(including repayments) with any of its other funds or property, but will hold
them separate and apart therefrom expressly in trust for Bank. Debtor will
forward to Bank such statements and reports of collection and adjustments as
Bank may from time to time specify. Bank will apply the whole or any part of the
collected funds received by it against the then outstanding Loans and any other
of Debtor's Obligations, the order and method of such application to be in the
discretion of Bank or Bank may, if it so elects, release the whole or any part
of such funds to Debtor for use in the operation of such Debtor's business. In
the event that Bank elects to give Debtor immediate credit for such funds as are
yet uncollected, Debtor agrees that Bank may make a charge for the float equal
to two (2) days' collection time at the Rate, payable monthly at the end of each
month. Debtor hereby authorizes Bank to charge to any deposit account of Debtor
any item of payment credited against any Obligations which is dishonored by the
drawee or maker thereof or, if funds are not available in a deposit account,
then to make an Advance therefor and charge the Loan Account accordingly.

           (d)   In addition to the foregoing, upon the occurrence of an Event
of Default, Bank may, in its sole discretion, require Debtor, at its own expense
and in the manner requested by Bank, to direct that remittances and all other
proceeds of Accounts and other Collateral shall be (i) sent to the post office
box designated by and/or in the name of Bank, or in the name of Debtor, but as
to which access is limited to Bank, (ii) deposited into a locked box at Bank,
and/or (iii) deposited into a bank account maintained in the name of Bank and/or
a blocked bank account under arrangements with the depository bank under which
all funds deposited to such 
<PAGE>
 
blocked bank account are required to be transferred solely to Bank. In
connection therewith, Debtor shall execute such post office box, locked box
and/or blocked bank account agreements as Bank shall specify.

           ------------------------

Event of Default hereunder and further provided that, in the reasonable opinion
of Bank, Debtor has not experienced an adverse material change in its financial
condition, Bank shall enter into an agreement, on terms and in form acceptable
to Bank, with such new lender whereby Bank shall share with such new lender, in
pari pasu, its security interest in the Collateral in excess of the amount of
all Loans and any other amounts due Bank by Debtor.

including proceeds of Collateral, that may be received by Bank or for the
benefit of Debtor. The proceeds of any sale or other disposition of all or any

        (c)   Third, to the payment in full of all other Obligations of Debtor
to Bank, and

           ----------------------------------  
times to enforce the provisions of this Agreement and the documents delivered
pursuant hereto in strict accordance with the terms hereof and thereof,
notwithstanding any conduct or custom on the part of Bank in refraining from so
doing at any time or times. The failure of Bank at any time or times to enforce
its rights under such provisions, strictly in accordance with the same, shall
not be construed as having created a custom in any way or manner contrary to
specific provisions of this Agreement or as having in any way or manner modified
or waived the same. All rights and remedies of Bank are cumulative and
concurrent and the exercise of one right or remedy shall not be deemed a waiver
or release of any other right or remedy.

                    SPECIAL RELEASE AND SETTLEMENT AGREEMENT


     This Special Release and Settlement Agreement (the "Agreement") is made and
entered into this 28th day of February, 1997 by and between Judith L. Hardardt,
an individual residing at RedGate Road, Morristown, New Jersey 07960
("Employee") and IBAH, Inc., a Delaware corporation with a principal place of
business at Four Valley Square, 512 Township Line Road, Blue Bell, Pennsylvania
19422 ("IBAH").

     WHEREAS, Employee has been an executive employee of IBAH pursuant to an
Employment Agreement, dated October 1, 1996 (the "Employment Agreement") by and
between Employee and IBAH; and

     NOW, THEREFORE, for good and valuable consideration, the receipt and
sufficiency of which is hereby acknowledged, AND INTENDING TO BE LEGALLY BOUND,
Employee and IBAH agree as follows:

1.  For a period of one year from the date of this Agreement, IBAH shall
continue to pay Employee's salary, as defined in the Employment Agreement, and
continue to cover Employee with group health insurance, life insurance and
disability benefits pursuant to the same terms and conditions offered to other
employees of IBAH.

2.  Section 7 of the Employment Agreement is incorporated into and made a part
of this Agreement with the understanding that the term of the Non-Competition
Period, as defined in the Employment Agreement, shall be for two years from the
date of this Agreement.

3.  During the Non-Competition Period, Employee shall not directly or indirectly
solicit any employee or consultant of IBAH to terminate or reduce their
employment or consultancy with IBAH.  Employee further agrees not to communicate
in any manner, directly or indirectly, with any employee or consultant of IBAH
regarding any aspect of the business or clients of IBAH during the Non-
Competition Period.

4.  Employee shall not be renominated for a position on the Board of Directors
of IBAH when her current term expires in June 1997.  IBAH shall not change or
amend the provision of the By-laws indemnifying directors of IBAH up to the
limits of the law unless such change or amendment shall apply to all directors
as a group.
<PAGE>
 
5.  In the event that either party elects to terminate the lease (the "Lease")
dated June 2, 1992 among William Hardardt, Employee and IBAH for a condominium
located at Unit 3A, 132 Claremont Road, Bernardsville, New Jersey, the party
terminating the Lease will give the other party three months written notice to
terminate the Lease and such notice shall be deemed sufficient notice to
terminate under the Lease.

6.  Except in connection with litigation or threatened litigation between the
parties to this Agreement, Employee agrees not to take any action or make any
statement, orally or in writing, which disparages or damages the reputation of
IBAH or any of its affiliates, officers, directors, employees, consultants,
agents, shareholders or representatives.  It shall not be a violation of this
Agreement, however, for Employee to respond truthfully to a subpoena or to a
request for information from any governmental agency or as may be required by
any law, statute, or administrative regulation.
 
    Except in connection with litigation or threatened litigation between the
parties to this Agreement, IBAH agrees not to take any action or make any

respond truthfully to a subpoena or to a request for information from any
governmental agency or as may be required by any law, statute, or administrative
regulation.

    Employee's departure from IBAH will be announced by posting of the notice

specifically set forth in this Agreement and those in Sections 8, 9,10 and 11 of

10.  In consideration for entering into this Agreement, consideration which
Employee hereby acknowledges, Employee does hereby release and forever discharge
IBAH and its present and former subsidiaries, affiliates, divisions, officers,
directors, partners, principals, employees, agents, predecessors, assigns,
servants, attorneys and insurers and each of them, and their respective
successors, assigns, heirs, administrators and personal representatives of and
from all actions and causes of action, suits, claims, debts and demands
whatsoever in law or equity, which Employee may have or claim to have against
IBAH as a result of her employment under the employment Agreement or separation
from employment, and does hereby covenant not to file a lawsuit to assert such
claims.  Employee is not being asked to, and does not release, any claim which
is nonwaivable as a matter of law.

     By this release, Employee knowingly and voluntarily waives any rights under
any and all laws which provide legal restrictions on IBAH's right to terminate

hereby acknowledges, IBAH does hereby release and forever discharge Employee and
her respective successors, assigns, heirs, administrators and personal
representatives of and from all actions and causes of action, suits, claims,
debts and demands whatsoever in law or equity, which IBAH may have or claim to
have against Employee as a result of her employment under the Employment
Agreement or separation from employment, and does hereby covenant not to file a
lawsuit to assert such claims.

12.  Employee acknowledges that she has been given twenty-one (21) days within
which to consider this Agreement and that she has consulted with an attorney
prior to executing this Agreement.  Employee has carefully read and understands
all provisions of this Agreement, which sets forth the entire agreement between
Employee and IBAH.  Employee acknowledges that she has not relied on any
representation, oral or written, not set forth in this Agreement.

13.  Employee further understands that she has a period of seven (7) days
following the signing of this Agreement to revoke this Agreement.  The Agreement
shall not become effective or enforceable until those seven (7) days have
expired.

14.  The failure of either party to enforce any provision of this Agreement
shall not be construed as a waiver or limitation of that party's right to
subsequently enforce and compel strict compliance with every provision of this
Agreement.

15.  This Agreement may be executed by the exchange of facsimile counterparts,
and the parties will exchange fully executed originals within thirty (30) days
of the date hereof.

     IN WITNESS WHEREOF, the parties hereto, intending to be legally bound, have
hereunto duly executed this Agreement the day and year first written above.

                         1997 EQUITY COMPENSATION PLAN
                         -----------------------------


     The purpose of the IBAH, Inc. 1997 Equity Compensation Plan (the "Plan") is
to provide (i) designated employees of IBAH, Inc. (the "Company") and its
subsidiaries, (ii) certain key advisors who perform services for the Company or
its subsidiaries and (iii) non-employee members of the Board of Directors of the
Company (the "Board") with the opportunity to receive grants of incentive stock
options and nonqualified stock options.  The Company believes that the Plan will
encourage the participants to contribute materially to the growth of the
Company, thereby benefitting the Company's stockholders, and will align the
economic interests of the participants with those of the stockholders.

     1.  Administration
         --------------

     (a) Committee.  The Plan shall be administered and interpreted by a
         ---------                                                      
committee (the "Committee"), which shall consist of two or more persons
appointed by the Board, all of whom shall be "outside directors" as defined
under section 162(m) of the Internal Revenue Code of 1986, as amended (the
"Code") and related Treasury regulations.  The Committee may also consist of
"non-employee directors" as defined in Rule 16b-3 under the Securities Exchange
Act of 1934, as amended (the "Exchange Act").  However, notwithstanding anything
in the Plan to the contrary, the Board must ratify or approve any grants made to
Non-Employee Directors. References in the Plan to the "Committee" shall be
deemed to include the Board, with respect to ratification or approval of grants
made to Non-Employee Directors.

     (b) Committee Authority.  The Committee shall have the sole authority to
         -------------------                                                 
(i) determine the individuals to whom grants shall be made under the Plan, (ii)
determine the type, size and terms of the grants to be made to each such
individual, (iii) determine the time when the grants will be made and the
duration of any applicable exercise or restriction period, including the
criteria for exercisability and the acceleration of exercisability and (iv) deal
with any other matters arising under the Plan.

     (c) Committee Determinations.  The Committee shall have full power and
         ------------------------                                          
authority to administer and interpret the Plan, to make factual determinations
and to adopt or amend such rules, regulations, agreements and instruments for
implementing the Plan and for the conduct of its business as it deems necessary
or advisable, in its sole discretion.  The Committee's interpretations of the
Plan and all determinations made by the Committee pursuant to the powers vested
in it hereunder shall be conclusive and binding on all persons having any
interest in the Plan or in any awards granted hereunder.  All powers of the
Committee shall be executed in its

sole discretion, in the best interest of the Company, not as a fiduciary, and in
keeping with the objectives of the Plan and need not be uniform as to similarly
situated individuals.

     2.  Options
         -------

     Awards under the Plan may consist of grants of incentive stock options
("Incentive Stock Options") or nonqualified stock options ("Nonqualified Stock
Options") as described in Section 5 (Incentive Stock Options and Nonqualified
Stock Options are collectively referred to as "Options").  All Options shall be
subject to the terms and conditions set forth herein and to such other terms and
conditions consistent with this Plan as the Committee deems appropriate and as
are specified in writing by the Committee to the individual in a grant
instrument (the "Grant Instrument") or an amendment to the Grant Instrument.
The Committee shall approve the form and provisions of each Grant Instrument.
Options need not be uniform as among the grantees.

     3.  Shares Subject to the Plan
         --------------------------

     (a) Shares Authorized.  Subject to the adjustment specified below, the
         -----------------                                                 
aggregate number of shares of common stock of the Company ("Company Stock") that
may be issued or transferred under the Plan is 1,500,000 shares, and the maximum
aggregate number of shares of Company Stock that shall be subject to Options
granted under the Plan to any individual during any calendar year shall be
200,000 shares.  The shares may be authorized but unissued shares of Company
Stock or reacquired shares of Company Stock, including shares purchased by the
Company on the open market for purposes of the Plan.  If and to the extent
Options granted under the Plan terminate, expire, or are canceled, forfeited,
exchanged or surrendered without having been exercised, the shares subject to
such grants shall again be available for purposes of the Plan.

     (b) Adjustments.  If there is any change in the number or kind of shares of
         -----------                                                            
Company Stock outstanding (i) by reason of a stock dividend, spinoff,
recapitalization, stock split, or combination or exchange of shares, (ii) by
reason of a merger, reorganization or consolidation in which the Company is the
surviving corporation, (iii) by reason of a reclassification or change in par
value, or (iv) by reason of any other extraordinary or unusual event affecting
the outstanding Company Stock as a class without the Company's receipt of
consideration, or if the value of outstanding shares of Company Stock is
substantially reduced as a result of a spinoff or the Company's payment of an
extraordinary dividend or distribution, the maximum number of shares of Company
Stock available for Options, the maximum number of shares of Company Stock for
which any individual participating in the Plan may be granted Options in any
year, the number of shares covered by outstanding Options, the kind of shares
issued under the Plan, and the price per share of such Options shall be
appropriately adjusted by the Committee to reflect any increase or decrease in
the number of, or change in the kind or value of, issued shares of Company Stock
to preclude, to the extent practicable, the enlargement or dilution of rights
and benefits under such Options; provided, however, that any fractional shares
resulting from such adjustment shall be

                                      A-2
<PAGE>
 
eliminated.  Any adjustments determined by the Committee shall be final, binding
and conclusive.

     4.  Eligibility for Participation
         -----------------------------

     (a) Eligible Persons.  All employees of the Company and its subsidiaries
         ----------------                                                    
("Employees"), including Employees who are officers or members of the Board, and
members of the Board who are not Employees ("Non-Employee Directors") shall be
eligible to participate in the Plan.  Key advisors who perform services to the
Company or any of its subsidiaries ("Key Advisors") shall be eligible to
participate in the Plan if the Key Advisors render bona fide services and such
services are not in connection with the offer or sale of securities in a
capital-raising transaction.

     (b) Selection of Grantees.  The Committee shall select the Employees, Non-
         ---------------------                                                
Employee Directors and Key Advisors to receive Options and shall determine the
number of shares of Company Stock subject to a particular Option in such manner
as the Committee determines.  Employees, Key Advisors and Non-Employee Directors
who receive Options under this Plan shall hereinafter be referred to as
"Grantees".

     5.  Granting of Options
         -------------------

     (a) Number of Shares.  The Committee shall determine the number of shares
         ----------------                                                     
of Company Stock that will be subject to each grant of Options to Employees,
Non-Employee Directors and Key Advisors.

     (b)  Type of Option and Price.
          ------------------------ 

          (i)   The Committee may grant Incentive Stock Options that are
intended to qualify as "incentive stock options" within the meaning of section
422 of the Code or Nonqualified Stock Options that are not intended so to
qualify, or any combination of Incentive Stock Options and Nonqualified Stock
Options, all in accordance with the terms and conditions set forth herein.
Incentive Stock Options may be granted only to Employees. Nonqualified Stock
Options may be granted to Employees, Non-Employee Directors and Key Advisors.

          (ii)  The purchase price (the "Exercise Price") of Company Stock
subject to an Option shall be determined by the Committee and may be equal to,
greater than, or less than the Fair Market Value (as defined below) of a share
of Company Stock on the date the Option is granted; provided, however, that (x)
the Exercise Price of an Incentive Stock Option shall be equal to, or greater
than, the Fair Market Value of a share of Company Stock on the date the
Incentive Stock Option is granted and (y) an Incentive Stock Option may not be
granted to an Employee who, at the time of grant, owns stock possessing more
than 10 percent of the total combined voting power of all classes of stock of
the Company or any parent or subsidiary of the

                                      A-3
<PAGE>
 
Company, unless the Exercise Price per share is not less than 110% of the Fair
Market Value of Company Stock on the date of grant.

         (iii)  If the Company Stock is publicly traded, then the Fair Market
Value per share shall be determined as follows: (x) if the principal trading
market for the Company Stock is a national securities exchange or the Nasdaq
National Market, the mean between the reported high and low sale prices thereof
on the relevant date or (if there were no trades on that date) the latest
preceding date upon which a sale was reported, or (y) if the Company Stock is
not principally traded on such exchange or market, the mean between the last
reported "bid" and "asked" prices of Company Stock on the relevant date, as
reported on Nasdaq or, if not so reported, as reported by the National Daily
Quotation Bureau, Inc. or as reported in a customary financial reporting
service, as applicable and as the Committee determines. If the Company Stock is
not publicly traded or, if publicly traded, is not subject to reported
transactions or "bid" or "asked" quotations as set forth above, the Fair Market
Value per share shall be as determined by the Committee.

     (c) Option Term.  The Committee shall determine the term of each Option.
         -----------                                                          
The term of any Option shall not exceed ten years from the date of grant.
However, an Incentive Stock Option that is granted to an Employee who, at the
time of grant, owns stock possessing more than 10 percent of the total combined
voting power of all classes of stock of the Company, or any parent or subsidiary
of the Company, may not have a term that exceeds five years from the date of
grant.

     (d) Exercisability of Options.  Options shall become exercisable in
         -------------------------                                      
accordance with such terms and conditions, consistent with the Plan, as may be
determined by the Committee and specified in the Grant Instrument or an
amendment to the Grant Instrument.  The Committee may accelerate the
exercisability of any or all outstanding Options at any time for any reason.

     (e) Termination of Employment, Disability or Death.
         ---------------------------------------------- 

         (i)  Except as provided below, an Option may only be exercised while
the Grantee is employed by, or providing services to, the Company as an
Employee, Key Advisor or member of the Board. In the event that a Grantee ceases
to be employed by, or provide services to, the Company for any reason other than
a "disability", death, or "termination for cause", any Option which is otherwise
exercisable by the Grantee shall terminate unless exercised within 90 days after
the date on which the Grantee ceases to be employed by, or provide services to,
the Company (or within such other period of time as may be specified by the
Committee), but in any event no later than the date of expiration of the Option
term. Any of the Grantee's Options that are not otherwise exercisable as of the
date on which the Grantee ceases to be employed by, or provide services to, the
Company shall terminate as of such date.

         (ii) In the event the Grantee ceases to be employed by, or provide
services to, the Company on account of a "termination for cause" by the Company,
any Option held by the

                                      A-4
<PAGE>
 
Grantee shall terminate as of the date the Grantee ceases to be employed by, or
provide services to, the Company.

     (iii)  In the event the Grantee ceases to be employed by, or provide
services to, the Company because the Grantee is "disabled", any Option which is
otherwise exercisable by the Grantee shall terminate unless exercised within one
year after the date on which the Grantee ceases to be employed by, or provide
services to, the Company (or within such other period of time as may be
specified by the Committee), but in any event no later than the date of
expiration of the Option term.  Any of the Grantee's Options which are not
otherwise exercisable as of the date on which the Grantee ceases to be employed
by, or provide services to, the Company shall terminate as of such date.

     (iv)   If the Grantee dies while employed by, or providing services to, the
Company or within 90 days after the date on which the Grantee ceases to be
employed by, or provide services to, the Company on account of a termination of
employment specified in Section 5(e)(i) above (or within such other period of
time as may be specified by the Committee), any Option that is otherwise
exercisable by the Grantee shall terminate unless exercised within one year
after the date on which the Grantee ceases to be employed by, or provide
services to, the Company (or within such other period of time as may be
specified by the Committee), but in any event no later than the date of
expiration of the Option term.  Any of the Grantee's Options that are not
otherwise exercisable as of the date on which the Grantee ceases to be employed
by, or provide services to, the Company shall terminate as of such date.

     (v)    For purposes of this Section 5(e):

     (A) The term "Company" shall mean the Company and its parent and subsidiary
corporations.

     (B) "Employed by, or provide services to, the Company" shall mean
employment or service as an Employee, Key Advisor or member of the Board, so
that, for purposes of exercising Options, a Grantee shall not be considered to
have terminated employment until the Grantee ceases to be an Employee, Key
Advisor and member of the Board, unless the Committee determines otherwise.

     (C) "Disability" shall mean a Grantee's becoming disabled within the
meaning of section 22(e)(3) of the Code.

     (D) "Termination for cause" shall mean, except to the extent specified
otherwise by the Committee, a finding by the Committee that the Grantee has
committed a material breach of his or her employment or service contract with
the Company, or has been engaged in disloyalty to the Company, including,
without limitation, fraud, embezzlement, theft, commission of a felony or proven
dishonesty in the course of his or her employment or service, or has disclosed
trade secrets or confidential information of

                                      A-5
<PAGE>
 
     the Company to persons not entitled to receive such information. In the
     event a Grantee's employment is terminated for cause, in addition to the
     immediate termination of all Options, the Grantee shall automatically
     forfeit all shares underlying any exercised portion of an Option for which
     the Company has not yet delivered the share certificates, upon refund by
     the Company of the Exercise Price paid by the Grantee for such shares.

     (f) Exercise of Options.  A Grantee may exercise an Option that has become
         -------------------                                                   
exercisable, in whole or in part, by delivering a notice of exercise to the
Company with payment of the Exercise Price.  The Grantee shall pay the Exercise
Price for an Option as specified by the Committee (x) in cash, (y) with the
approval of the Committee, by delivering shares of Company Stock owned by the
Grantee (including Company Stock acquired in connection with the exercise of an
Option, subject to such restrictions as the Committee deems appropriate) and
having a Fair Market Value on the date of exercise equal to the Exercise Price
or (z) by such other method as the Committee may approve, including payment
through a broker in accordance with procedures permitted by Regulation T of the
Federal Reserve Board.  Shares of Company Stock used to exercise an Option shall
have been held by the Grantee for the requisite period of time to avoid adverse
accounting consequences to the Company with respect to the Option.  The Grantee
shall pay the Exercise Price and the amount of any withholding tax due (pursuant
to Section 6) at the time of exercise.

     (g) Limits on Incentive Stock Options.  Each Incentive Stock Option shall
         ---------------------------------                                    
provide that, if the aggregate Fair Market Value of the stock on the date of the
grant with respect to which Incentive Stock Options are exercisable for the
first time by a Grantee during any calendar year, under the Plan or any other
stock option plan of the Company or a parent or subsidiary, exceeds $100,000,
then the Option, as to the excess, shall be treated as a Nonqualified Stock
Option.  An Incentive Stock Option shall not be granted to any person who is not
an Employee of the Company or a parent or subsidiary (within the meaning of
section 424(f) of the Code).

     6.  Withholding of Taxes
         --------------------

     (a) Required Withholding.  All Options under the Plan shall be subject to
         --------------------                                                 
applicable federal (including FICA), state and local tax withholding
requirements.  The Company may require the Grantee or other person receiving
shares upon the exercise of Options to pay to the Company the amount of any
federal, state or local taxes that the Company is required to withhold with
respect to such Options, or the Company may deduct from other wages paid by the
Company the amount of any withholding taxes due with respect to such Options.

     (b) Election to Withhold Shares.  If the Committee so permits, a Grantee
         ---------------------------                                         
may elect to satisfy the Company's income tax withholding obligation with
respect to an Option by having shares withheld up to an amount that does not
exceed the Grantee's maximum marginal tax rate for federal (including FICA),
state and local tax liabilities.  The election must be in a form and manner
prescribed by the Committee and shall be subject to the prior approval of the
Committee.

                                      A-6
<PAGE>
 
     7.  Transferability of Options
         --------------------------

     (a) Nontransferability of Options.  Except as provided below, only the
         -----------------------------                                     
Grantee may exercise rights under an Option during the Grantee's lifetime.  A
Grantee may not transfer those rights except by will or by the laws of descent
and distribution or, with respect to Nonqualified Stock Options, if permitted in
any specific case by the Committee, pursuant to a domestic relations order (as
defined under the Code or Title I of the Employee Retirement Income Security Act
of 1974, as amended, or the regulations thereunder).  When a Grantee dies, the
personal representative or other person entitled to succeed to the rights of the
Grantee ("Successor Grantee") may exercise such rights.  A Successor Grantee
must furnish proof satisfactory to the Company of his or her right to receive
the Option under the Grantee's will or under the applicable laws of descent and
distribution.

     (b) Transfer of Nonqualified Stock Options. Notwithstanding the foregoing,
         --------------------------------------                                
the Committee may provide, in a Grant Instrument, that a Grantee may transfer
Nonqualified Stock Options to family members or other persons or entities
according to such terms as the Committee may determine; provided that the
Grantee receives no consideration for the transfer of an Option and the
transferred Option shall continue to be subject to the same terms and conditions
as were applicable to the Option immediately before the transfer.

     8.  Change of Control of the Company
         --------------------------------

     As used herein, a "Change of Control" shall be deemed to have occurred if:

     (a) Any "person" (as such term is used in Sections 13(d) and 14(d) of the
Exchange Act) becomes a "beneficial owner" (as defined in Rule 13d-3 under the
Exchange Act), directly or indirectly, of securities of the Company representing
more than 50% of the voting power of the then outstanding securities of the
Company, except where the acquisition is approved by the Board;

     (b) The stockholders of the Company approve (or, if stockholder approval is
not required, the Board approves) an agreement providing for (i) the merger or
consolidation of the Company with another corporation where the stockholders of
the Company, immediately prior to the merger or consolidation, will not
beneficially own, immediately after the merger or consolidation, shares
entitling such stockholders to more than 50% of all votes to which all
stockholders of the surviving corporation would be entitled in the election of
directors (without consideration of the rights of any class of stock to elect
directors by a separate class vote), or where the members of the Board,
immediately prior to the merger or consolidation, would not, immediately after
the merger or consolidation, constitute a majority of the board of directors of
the surviving corporation, (ii) the sale or other disposition of all or
substantially all of the assets of the Company, or (iii) a liquidation or
dissolution of the Company;

                                      A-7
<PAGE>
 
     (c) Any person has commenced a tender offer or exchange offer for or more
than 50% of the voting power of the then outstanding shares of the Company; or

     (d) At least a majority of the Board does not consist of individuals who
were elected, or nominated for election, by the directors in office at the time
of such election or nomination.

     9.  Consequences of a Change of Control
         -----------------------------------

     (a) Notice and Acceleration.  Upon a Change of Control, unless the
         -----------------------                                       
Committee determines otherwise, (i) the Company shall provide each Grantee with
outstanding Options written notice of such Change of Control and (ii) all
outstanding Options that are not then exercisable shall automatically accelerate
and become fully exercisable.

     (b) Assumption of Options.  Upon a Change of Control where the Company is
         ---------------------                                                
not the surviving corporation (or survives only as a subsidiary of another
corporation), unless the Committee determines otherwise, all outstanding Options
that are not exercised shall be assumed by, or replaced with comparable options
by, the surviving corporation.

     (c) Other Alternatives.  Notwithstanding the foregoing, subject to
         ------------------                                            
subsection (e) below, in the event of a Change of Control, the Committee may
take one or both of the following actions: the Committee may (i) require that
Grantees surrender their outstanding Options in exchange for a payment by the
Company, in cash or Company Stock as determined by the Committee, in an amount
equal to the amount by which the then Fair Market Value of the shares of Company
Stock subject to the Grantee's unexercised Options exceeds the Exercise Price of
the Options, or (ii) after giving Grantees an opportunity to exercise their
outstanding Options, terminate any or all unexercised Options at such time as
the Committee deems appropriate.  Such surrender or termination shall take place
as of the date of the Change of Control or such other date as the Committee may
specify.

     (d) Committee.  The Committee making the determinations under this Section
         ---------                                                             
9 following a Change of Control must be comprised of the same members as those
on the Committee immediately before the Change of Control.  If the Committee
members do not meet this requirement, the automatic provisions of Subsections
(a) and (b) shall apply, and the Committee shall not have discretion to vary
them with respect to an outstanding Option without the consent of the Grantee.

     (e) Limitations.  Notwithstanding anything in the Plan to the contrary, in
         -----------                                                           
the event of a Change of Control, the Committee shall not have the right to take
any actions described in the Plan (including without limitation actions
described in subsection (c) above) that would make the Change of Control
ineligible for pooling of interests accounting treatment or that would make the
Change of Control ineligible for desired tax treatment if, in the absence of
such right, the Change of Control would qualify for such treatment and the
Company intends to use such treatment with respect to the Change of Control.

     10. Amendment and Termination of the Plan
         -------------------------------------

     (a) Amendment.  The Board may amend or terminate the Plan at any time;
         ---------                                                         
provided, however, that the Board shall not amend the Plan without stockholder
approval if such approval is required by Section 162(m) of the Code.

     (b) Termination of Plan.  The Plan shall terminate on the day immediately
         -------------------                                                  
preceding the tenth anniversary of its effective date, unless the Plan is
terminated earlier by the Board or is extended by the Board with the approval of
the stockholders.

     (c) Termination and Amendment of Outstanding Options.  A termination or
         ------------------------------------------------                   
amendment of the Plan that occurs after an Option is made shall not materially
impair the rights of a Grantee unless the Grantee consents or unless the
Committee acts under Section 17(b).  The termination of the Plan shall not
impair the power and authority of the Committee with respect to an outstanding
Option.  Whether or not the Plan has terminated, an outstanding Option may be
terminated or amended under Section 17(b) or may be amended by agreement of the
Company and the Grantee consistent with the Plan.

     (d) Governing Document.  The Plan shall be the controlling document.  No
         ------------------                                                  
other statements, representations, explanatory materials or examples, oral or
written, may amend the Plan in any manner.  The Plan shall be binding upon and
enforceable against the Company and its successors and assigns.

     11. Funding of the Plan
         -------------------

     This Plan shall be unfunded.  The Company shall not be required to
establish any special or separate fund or to make any other segregation of
assets to assure the payment of any Options under this Plan.  In no event shall
interest be paid or accrued on any Option.

     12. Rights of Participants
         ----------------------

     Nothing in this Plan shall entitle any Employee, Non-Employee Director, Key
Advisor or other person to any claim or right to be granted an Option under this
Plan.  Neither this Plan nor any action taken hereunder shall be construed as
giving any individual any rights to be retained by or in the employ of the
Company or any other employment rights.

     13. No Fractional Shares
         --------------------

     No fractional shares of Company Stock shall be issued or delivered pursuant
to the Plan or any Option.  The Committee shall determine whether cash, other
awards or other property shall be issued or paid in lieu of such fractional
shares or whether such fractional shares or any rights thereto shall be
forfeited or otherwise eliminated.

                                      A-9
<PAGE>
 
     14.  Requirements for Issuance or Transfer of Shares
          -----------------------------------------------

     No Company Stock shall be issued or transferred in connection with any
Option hereunder unless and until all legal requirements applicable to the
issuance or transfer of such Company Stock have been complied with to the
satisfaction of the Committee.  The Committee shall have the right to condition
any Option granted to any Grantee hereunder on such Grantee's undertaking in
writing to comply with such restrictions on his or her subsequent disposition of
such shares of Company Stock as the Committee shall deem necessary or advisable
as a result of any applicable law, regulation or official interpretation
thereof, and certificates representing such shares may be legended to reflect
any such restrictions.  Certificates representing shares of Company Stock issued
or transferred under the Plan will be subject to such stop-transfer orders and
other restrictions as may be required by applicable laws, regulations and
interpretations, including any requirement that a legend be placed thereon.

     15.  Headings
          --------

     Section headings are for reference only.  In the event of a conflict
between a title and the content of a Section, the content of the Section shall
control.

     16.  Effective Date of the Plan.
          -------------------------- 

     Subject to approval by the Company's stockholders, the Plan shall be
effective on January 1, 1997.

     17.  Miscellaneous
          -------------

     (a)  Grants in Connection with Corporate Transactions and Otherwise.
          --------------------------------------------------------------  
Nothing contained in this Plan shall be construed to (i) limit the right of the
Committee to make grants under this Plan in connection with the acquisition, by
purchase, lease, merger, consolidation or otherwise, of the business or assets
of any corporation, firm or association, including grants to employees thereof
who become Employees of the Company, or for other proper corporate purposes, or
(ii) limit the right of the Company to grant stock options or make other awards
outside of this Plan.  Without limiting the foregoing, the Committee may grant

     In the event that, at the commencement of the term of this lease, or 
thereafter, Tenant shall be in default in the payment of rent to Owner pursuant 
to the terms of another lease with Owner of with Owner's predecessor in 
interest, Owner may at Owner's option and without notice to Tenant add the 
amount of such arrears to any monthly installment of rent payable hereunder and 
the same shall be payable to Owner as additional rent.

     The Parties hereto, for themselves, their heirs, distributees, executors, 
administrators, legal representatives, successors and assigns, hereby covenant 
as follows:

RENT           

          1.   Tenant shall pay the rent as above and as hereinafter provided.

OCCUPANCY

          2.   Tenant shall use and occupy demised premises for general
executive and administrative offices only and for no other purpose.

TENANT ALTERATIONS

          3.   Except for the initial work performed on Tenant's behalf at the
commencement of the lease term, Tenant shall make no other changes in or to the
demised premises of any nature without Owner's prior written consent. Subject to
the prior written consent of Owner, and to the provisions of this article.
Tenant at Tenant's expense, may make alterations, installations, additions or
improvements which are non-structural and which do not affect utility services
or plumbing and electrical lines, in or to the interior of the demised premises
by using contractors or mechanics first approved by Owner. Tenant shall, before
making any alterations, additions, installations or improvements, at its
expense, obtain all permits, approvals and certificates required by any
governmental or quasi-governmental bodies and (upon completion) certificates of
final approval thereof and shall deliver promptly duplicates of all such
permits, approvals and certificates to Owner and Tenant agrees to carry and will
cause Tenant's contractors and sub-contractors to carry such workman's
compensation, general liability, personal and property damage insurance as Owner
may require. If any mechanic's lien is filed against the demised premises, or
the building of which the same forms a part, for work claimed to have been done
for, or materials furnished to, Tenant, whether or not done pursuant to this
article, the same shall be discharged by Tenant within thirty days thereafter,
at Tenant's expense, by filing the bond required by law. Except for the initial
work performed on Tenant's behalf at the commencement of the lease term, all
other fixtures and all paneling, cables, telephones wires, partitions, railings
and like installations, installed in the premises at any time, either by Tenant
or by Owner in Tenant's behalf, shall, upon installation, become the property of
Owner and shall remain upon and be surrendered with the demised premises unless
Owner, by notice to Tenant no later than twenty days prior to the date fixed as
the termination of this lease, elects to relinquish Owner's right thereto and to
have them removed by Tenant, in which event the same shall be removed from the
premises by Tenant prior to the expiration of the lease, at Tenant's expense.
Nothing in this Article shall be construed to give Owner title to or to prevent
Tenant's removal of trade fixtures, moveable office furniture and equipment, but
upon removal of any such from the premises or upon removal of other
installations as may be required by Owner, Tenant shall immediately and at its
expense, repair and restore the premises to the condition existing prior to
installation and repair any damage to the demised premises or the building due
to such removal, reasonable wear and tear excepted. All property permitted or
required to be removed, by Tenant at the end of the term remaining in the
premises after Tenant's removal shall be deemed abandoned and may, at the
election of Owner, either be retained as Owner's property or may be removed from
the premises by Owner, at Tenant's expense.

MAINTENANCE AND REPAIRS

          4.   Tenant shall, throughout the term of this lease, take good care 
of the demised premises and the fixtures and appurtenances therein. Tenant shall
be responsible for all damage or injury to the demised premises or any other
part of the building and the systems and equipment thereof, whether requiring
structural or nonstructural repairs caused by or resulting from carelessness,
omission, neglect or improper conduct of Tenant, Tenant's subtenants, agents,
employees, invitees or licensees, or which arise out of any work, labor, service
or equipment done for or supplied to Tenant or any subtenant or arising out of
the installation, use or operation of the property or equipment of Tenant or any
subtenant. Tenant shall also repair all damage to the building and the demised
premises caused by the moving of Tenant's fixtures, furniture and equipment.
Tenant shall promptly make, at Tenant's expense, all repairs in and to the
demised premises for which Tenant is responsible, using only the contractor for
the trade or trades in question, selected from a list of at least two
contractors per trade submitted by Owner. Any other repairs in or to the
building or the facilities and systems thereof for which Tenant is responsible
shall be performed by Owner at the Tenant's expense. Owner shall maintain in
good working order and repair the exterior and the structural portions of the
building, including the structural portions of its demised premises, and the
public portions of the building interior and the building plumbing, electrical,
heating and ventilating systems (to the extent such systems presently exist)
serving the demised premises. Tenant agrees to give prompt notice of any
defective condition in the premises for which Owner may be responsible
hereunder. Except for Owner's gross negligence or wilfull misconduct, there
shall be no allowance to Tenant for diminution of rental value and no liability
on the part of Owner by reason of inconvenience, annoyance or injury to business
arising from Owner or others making repairs, alterations, additions or
improvements in or to any portion of the building or the demised premises or in
and to the fixtures, appurtenances or equipment thereof. It is specifically
agreed that Tenant shall not be entitled to any setoff or reduction of rent by
reason of any failure of Owner to comply with the covenants of this or any other
article of this Lease. Tenant agrees that Tenant's sole remedy at law in such
instance will be by way of an action for damages for breach of contract. The
provisions of this Article 4 shall not apply in the case of fire or other
casualty which are dealt with in Article 9 hereof.

WINDOW CLEANING

          5.   Tenant will not clean nor require, permit, suffer or allow any 
window in the demised premises to be cleaned from the outside.

REQUIREMENTS OF LAW, FIRE INSURANCE, FLOOR LOADS

          6.   Prior to the commencement of the lease term, if Tenant is then in
possession, and at all times thereafter, Tenant, at Tenant's sole cost and 
expense, shall promptly comply with all present and future laws, orders and 
regulations of all state, federal, municipal and local governments, departments,
commissions and boards and any direction of any public officer pursuant to law, 
and all orders, rules and regulations of any body which shall impose any 
violation, order or duty upon Owner or Tenant with respect to the demised 
premises, arising out of Tenant's use or manner of use thereof, (including 
Tenant's permitted use) or, with respect to the building if arising out of 
Tenant's use or manner of use of the premises or the building (including the use
permitted under the lease). Nothing herein shall require Tenant to make 
structural repairs or alterations unless Tenant has, by its manner of use of the
demised premises or method of operation therein, violated any such laws, 
ordinances, orders, rules, regulations or requirements with respect thereto. 
Tenant may, after securing Owner to Owner's satisfaction against all damages, 
interest, penalties and expenses, including, but not limited to, reasonable 
attorney's fees, by cash deposit or by surety bond in an amount and in a company
satisfactory to Owner, contest and appeal any such laws, ordinances, orders, 
rules, regulations or requirements provided some is done with all reasonable 
promptness and provided such appeal shall not subject Owner to prosecution for a
criminal offense or constitute a default under any lease or mortgage under which
Owner may be obligated, or cause the demised premises or any part thereof to be 
condemned or vacated. Tenant shall not do or permit any act or thing to be done 
in or to the demised premises which is contrary to law, or which will invalidate
or be in conflict with public liability, fire or other policies of insurance at 
any time carried by or for the benefit of Owner with respect to the demised 
premises or the building of which the demised premises form a part, or which 
shall or might subject Owner to any liability or responsibility to any person or
for property damage. Tenant shall not keep anything in the demised premises 
except as now or hereafter permitted by the Fire Department, Board of Fire 
Underwriters, Fire Insurance Rating Organization or other authority having 
jurisdiction, and then only in such manner and such quantity so as not to 
increase the rate for fire insurance applicable to the building, nor use the 
premises in a manner which will increase the insurance rate for the building or 
any property located therein over that in effect prior to the commencement of 
Tenant's occupancy. Tenant shall pay all costs, expenses, fines, penalties, or 
damages, which may be imposed upon Owner by reason of Tenant's failure to comply
with the provisions of this article and if by reason of such failure the fire 
insurance rate shall, at the beginning of this lease or at any time thereafter, 
be higher than it otherwise would be, then Tenant shall reimburse Owner, as 
additional rent hereunder, for that portion of all fire insurance premiums 
thereafter paid by Owner which shall have been charged because of such failure 
by Tenant. In any action or proceeding wherein Owner and Tenant are parties, a 
schedule or "make-up" of rate for the building or demised premises issued by any
body making fire insurance rates applicable to said premises shall be conclusive
evidence of the facts therein stated and of the several items and charges in the
fire insurance rates then applicable to said premises. Tenant shall not place a
load upon any floor of the demised premises exceeding the floor load per square
foot area which it was designed to carry and which is allowed by law. Owner
reserves the right to prescribe the weight and position of all safes, business
machines and mechanical equipment. Such installations shall be placed and
maintained by Tenant, at Tenant's expense, in settings sufficient, in Owner's
reasonable judgement, to absorb and prevent vibration, noise and annoyance to
other tenants of the building.

SUBORDINATION

          7.   (a)  This lease is subject and subordinate to all ground or 
underlying leases and to all mortgages which may now or hereafter affect such 
leases or the real property of which demised premises are a part and to all 
renewals, modifications, consolidations,

<PAGE>
 
replacements and extensions of any such underlying leases and mortgages. This 
clause shall be self-operative and no further instrument of subordination shall
be required by any ground or underlying lessor or by any mortgagee, affecting
any lease or the real property of which the demised premises are a part. In
confirmation of such subordination, Tenant shall execute promptly any
certificate that Owner may request.

               (b)  With respect to all mortgages which may as of the date
hereof affect this Lease or the building of which the demised premises form a 
part, Owner agrees that upon Tenant's written request received by Owner within 
ten (10) days after the date hereof (time being of the essence), Owner shall 
endeavor to use reasonable efforts (at no cost or expense to Owner) to obtain a 
non-disturbance and attornment agreement in recordable form from the holder of 
any such mortgage, providing in substance that so long as Tenant shall have 
entered into possession and occupancy of the demised premises and commenced 
payment of Minimum Rent and additional rent due hereunder, and so long as Tenant
has not breached its obligations for the timely payment of Minimum Rent and 
additional rent and in the performance of the other terms, covenants and 
conditions to be performed or observed on Tenant's part under the Lease. 
Tenant's possession of the demised premises will not be disturbed during the 
term hereof, notwithstanding the foreclosure of any such mortgage, and Tenant 
will not be named as a party defendant in any foreclosure proceedings brought 
for the recovery of possession, it being hereby covenanted and agreed by Tenant 
that the holder of any such mortgage, or anyone claiming by, through or under 
said holder shall not be (i) liable for any act or omission for any prior 
landlord (including Owner), or (ii) subject to any offsets or defenses which 
Tenant might have against any prior landlord (including Owner), or (iii) bound 
by any Minimum Rent, Adjusted Minimum rent or additional rent or other charges 
which Tenant might have paid for more than the current month to a prior landlord
(including Owner), or (iv) bound by any modifications of this Lease made without
the written consent of such mortgagee.

               (c)  The failure of Owner to obtain a non-disturbance and 
attornment agreement shall not be deemed a default on Owner's part of its 
obligations hereunder, or impose any claim in favor of Tenant against Owner by 
reason thereof, or affect the validity of this Lease. Tenant agrees to (i) 
execute and deliver to such mortgagee a non-disturbance and attornment agreement
in form and substance satisfactory to and customarily adopted by such mortgagee 
and (ii) reimburse Owner for all expenses incurred by Owner in connection 
therewith, including legal expenses.

injury or damage to persons or property resulting from any cause of whatsoever 
nature, unless caused by or due to the negligence of Owner, its agents, servants
or employees. Owner or its agents will not be liable for any such damage caused

fees, paid, suffered or incurred as a result of any breach by Tenant, Tenant's 
agents, contractors, employees, invitees, or licensees, of any covenant or 
condition of this lease, or the carelessness, negligence or improper conduct of 
the Tenant, Tenant's agents, contractors, employees, invitees or licensees. 
Tenant's liability under this lease extends to the acts and omissions of any 
sub-tenant, and any agent, contractor, employee, invitee or licensee of any 
sub-tenant. In case any action or proceeding is brought against Owner by reason 
of any such claim, Tenant, upon written notice from Owner, will, at Tenant's 
expense, resist or defend such action or proceeding by counsel approved by Owner
in writing, such approval not to be unreasonably withheld.

fire or other casualty, Tenant shall give immediate notice thereof to Owner and
this lease shall continue in full force and effect except as hereinafter set
forth. (b) If the demised premises are partially damaged or rendered partially
unusable by fire or other casualty, Owner shall notify Tenant of its intention
to restore said damage which shall be repaired by and at the expense of Owner
and the rent, until such repair shall be substantially completed, shall be
apportioned from the day following the casualty according to the part of the
premises which is usable. (c) If the demised premises are totally damaged or
rendered wholly unusable by fire or other casualty, then the rent shall be
proportionately paid up to the time of the casualty and thenceforth shall cease
until the date when the premises shall have been repaired and restored by Owner,
subject to Owner's right to elect not to restore the same as hereinafter
provided. (d) If the demised premises are rendered wholly unusable or (whether
or not the demised premises are damaged in whole or in part) if the building
shall be so damaged that Owner shall decide to demolish it or to rebuild it,
then, in any of such events, Owner may elect to terminate this lease by written
notice to Tenant, given within 90 days after such fire or casualty, specifying a
date for the expiration of the lease, which date shall not be more than 60 days
after the giving of such notice, and upon the date specified in such notice the
term of this lease shall expire as fully and completely as if such date were the
date set forth above for the termination of this lease and Tenant shall
forthwith quit, surrender and vacate the premises without prejudice however, to
Landlord's rights and remedies against Tenant under the lease provisions in
effect prior to such termination, and any rent owing shall be paid up to such
date and any payments of rent made by Tenant which were on account of any period
subsequent to such date shall be returned to Tenant. Unless Owner shall serve a
termination notice as provided for herein, Owner shall make the repairs and
restorations under the conditions of (b) and (c) hereof, with all reasonable
expedition, subject to delays due to adjustment of insurance claims, labor
troubles and causes beyond Owner's reasonable control. After any such casualty,
Tenant shall cooperate with Owner's restoration by removing from the premises as
promptly as reasonably possible, all of Tenant's salvageable inventory and
movable equipment, furniture, and other property. Tenant's liability for rent
shall resume ten (10) days after written notice from Owner that the premises are
substantially ready for Tenant's occupancy. In the event (i) the demised
premises shall be damaged by fire or other casualty during the term and Tenant
shall be unable to use the demised premises as a result of such damage and (ii)
Owner shall not exercise the right to terminate this Lease and shall,
accordingly, be obligated to repair any such damage pursuant to the provisions
hereof, and (iii) Owner shall have failed to repair such damage within six (6)
months after the date of such fire or other casualty, as such period shall be
extended by the number of days that Owner is delayed in completing such
restoration by any cause or factor beyond Owner's reasonable control, including,
but not limited to, Tenant's failure to cooperate with Owner, strikes or other
labor disputes, accidents, orders or regulations of any Federal, State, County
or Municipal Authority, delays due to adjustment of insurance claims, lack of
availability of materials, parts or utility services, acts of God, fire,
earthquake, floods, explosion, action of the elements, war, hostilities,
invasion, insurrection, riot, mob violence, sabotage, or by reason of any other
cause, whether similar or not to the foregoing, that is beyond the reasonable
control of Owner, (such six (6) month period as so extended is referred to as
the "Restoration Period"), then, in such event, Tenant shall have a one time
option to give the Owner, within ten (10) days next following the expiration of
the Restoration Period, time being of the essence, a thirty (30) day notice of
termination of this Lease and upon the expiration of said thirty (30) days, this
Lease and the term thereunder shall end and expire as fully and completely as if
the expiration of such thirty (30) day period were the day herein definitely
fixed for the end and expiration of this Lease and the term thereof and Tenant
shall then quit and surrender the demised premises to Owner but Tenant shall
remain liable through and including the date of such damage as provided in this
Lease. Failure of Tenant to timely deliver a thirty (30) day notice of
termination shall be conclusively deemed to be an express election by Tenant to
waive Tenant's right to terminate the Lease as provided in this Article 9. (e)
Nothing contained hereinabove shall relieve Tenant from liability that may exist
as a result of damage from fire or other casualty. Notwithstanding the
foregoing, each party shall look first to any insurance in its favor before
making any claim against the other party for recovery for loss or damage
resulting from fire or other casualty, and to the extent that such insurance is
in force and collectible and to the extent permitted by law, Owner and Tenant
each hereby releases and waives all right of recovery against the other or any
one claiming through or under each of them by way of subrogation or otherwise.
The foregoing release and waiver shall be in force only if both relessors'
insurance policies contain a clause providing that such a release or waiver
shall not invalidate the insurance. If, and to the extent, that such waiver can
be obtained only by the payment of additional premiums, then the party
benefiting from the waiver shall pay such premium within ten days after written
demand or shall be deemed to have agreed that the party obtaining insurance
coverage shall be free of any further obligation under the provisions hereof
with respect to waiver of subrogation. Tenant acknowledges that Owner will not
carry insurance on Tenant's furniture and/or furnishings or any fixtures or
equipment, improvements, or appurtenances removable by Tenant and agrees that
Owner will not be obligated to repair any damage thereto or replace the same.

EMIMENT DOMAIN 

          10. If the whole or any part of the demised premises shall be acquired
or condemned by Emiment Domain for any public or quasi public use or purpose, 
then and in that event, the term of this lease shall cease and terminate from 
the date of title vesting in such proceeding and Tenant shall have no claim for 
the value of any unexpired term of said lease and assigns to Owner. Tenant's 
entire interest in any such award. Tenant shall be permitted to prosecute its 
own claim against the condemning authority for moving expenses and other 
damages provided Tenant's award does not in any way diminish Owner's award 
hereunder.

ASSIGNMENT, MORTGAGE, ETC.

          11. Tenant, for itself, its heirs, distributees, executors, 
administrators, legal representatives, successors and assigns, expressly 
covenants that it shall not assign, mortgage or encumber this agreements, nor 
underlet, or suffer or permit the demised premises or any part thereof to be 
used by others, without the prior written consent of Owner in each instance. 
Subject to Article 48 hereof, transfer of the majority of the stock of a 
corporate Tenant shall be 
<PAGE>
 
deemed an assignment.  If this lease be assigned, or if the demised premises or 
any part thereof be underlet or occupied by anybody other than Tenant.  Owner 
may, after default by Tenant, collect rent from the assignee, under-tenant or 
occupant, and apply the net amount collected to the rent herein reserved, but no
such assignment, underletting, occupancy or collection shall be deemed a waiver 
of this covenant, or the acceptance of the assignee, under-tenant or occupant as
tenant, or a release of Tenant from the further performance by Tenant of 
covenants on the part of Tenant herein contained.  The consent by Owner to an 
assignment or underletting shall not in any wise be construed to relieve Tenant 
from obtaining the express consent in writing of Owner to any further 
assignment or underletting.

ELECTRIC CURRENT  

          12.  Tenant covenants and agrees that at all times its use of electric
current shall not exceed the capacity 6 existing feeders to the building or the
risers or wiring installation and Tenant may not use any electrical equipment
which, in Owner's opinion, reasonably exercised, will overload such
installations or interfere with the use thereof by other tenants of the
building. The change at any time of the character of electric service shall 
in no wise make owner liable or responsible to Tenant, for any loss, damages or
expenses which Tenant may sustain.

ACCESS TO PREMISES  

          13.  Owner or Owner's agents shall have the right (but shall not be
obligated) to enter the demised premises in any emergency at any time, and, at
other reasonable times during normal business hours, to examine the same and to
make such repairs, replacements and improvements as Owner may deem necessary and
reasonably desirable to the demised premises or to any other portion of the
building or which Owner may elect to perform. Tenant shall permit Owner to use
and maintain and replace pipes and conduits in and through the demised premises
and to erect new pipes and conduits therein provided they are concealed
within the walls, floor, or ceiling. Owner may, during the progress of any work
in the demised premises, take all necessary materials and equipment into said
premises without the same constituting an eviction nor shall the Tenant be
entitled to any abatement of rent while such work is in progress nor to any
damages by reason of loss or interruption of business or otherwise.  Throughout
the term hereof Owner shall have the right to enter the demised premises at
reasonable hours upon reasonable notice for the purpose of showing the same to
prospective purchases or mortgagees of the building, and during the last six
months of the term for the purpose of showing the same to prospective tenants.
If Tenant is not present to open and permit an entry into the premises, Owner or
Owner's agents may enter the same whenever such entry may be necessary or
permissible by master key or forcibly and provided reasonable care is exercised
to safeguard Tenant's property, such entry shall not render Owner or its agents
liable therefor, nor in any event shall the obligations of Tenant hereunder be
affected. If during the last month of the term Tenant shall have removed all or
substantially all of Tenant's property therefrom, Owner may immediately enter,
alter, renovate or redecorate the demised premises without limitation or
abatement of rent, or incurring liability to Tenant for any compensation and
such act shall have no effect on this lease or Tenant's obligations hereunder.

          14.  Landlord reserves the right to establish a no smoking policy in
some or all common areas of the building including but not limited to elevators,
lobbies, atriums, stairwells, corridors and restrooms.

CERTIFICATE OF OCCUPANCY

violation of the certificate of occupancy issued for the building of which the
demised premises are a part. Tenant has inspected the premises and accepts them
as is, subject to the rider annexed hereto with respect to Owner's work, if any.
In any event, Owner makes no representation as to the condition of the premises
and Tenant agrees to accept the same subject to violations, whether or not of
record.

BANKRUPTCY   

          16.  (a) Anything elsewhere in this lease to the contrary
notwithstanding, this lease may be cancelled by Owner by the sending of a
written notice to Tenant within a reasonable time after the happening of any one
or more of the following events: (1) the commencement of a case in bankruptcy or
under the laws of any state naming Tenant as the debtor; or (2) the making by
Tenant of an assignment or any other arrangement for the benefit of creditors
under any state statute. Neither Tenant nor any person claiming through or under
Tenant, or by reason of any statute or order of court, shall thereafter be
entitled to possession of the premises demised but shall forthwith quit and
surrender the premises. If this lease shall be assigned in accordance with its
terms, the provisions of this Article 16 shall be applicable only to the party
then owning Tenant's interest in this lease.

          (b)  it is stipulated and agreed that in the event of the termination
of this lease pursuant to (a) hereof, Owner shall forthwith, notwithstanding any
other provisions of this lease to the contrary, be entitled to recover from
Tenant as and for liquidated damages an amount equal to the difference between
the rent reserved hereunder for the unexpired portion of the term demised and
the fair and reasonable rental value of the demised premises for the same
period. In the computation of such damages the difference between any
installment of rent becoming due hereunder after the date of termination and the
fair and reasonable rental value of the demised premises for the period for
which such installment was payable shall be discounted to the date of
termination at the rate of four percent (4%) per annum. If such premises or any
part thereof be relet by the Owner for the unexpired term of said lease, or any
part thereof, before presentation of proof of such liquidated damages to any
court, commission or tribunal, the amount of rent reserved upon such reletting
shall be deemed to be the fair and reasonable rental value for the part or the
whole of the premises so re-let during the term of the re-letting.  Nothing
herein contained shall limit or prejudice the right of the Owner to prove for
and obtain as liquidated damages by reason of such termination, an amount equal
to the maximum allowed by any statute or rule of law in effect at the time when,
and governing the proceedings in which, such damages are to be proved, whether
or not such amount be greater, equal to, or less than the amount of the
difference referred to above.

DEFAULT   
          
          17.  (1)  If Tenant defaults in fulfilling any of the covenants of 
this lease other than the covenants for the payment of rent or additional rent;
or if the demised premises becomes vacant or deserted; or if any execution or
attachment shall be issued against Tenant or any of Tenant's property whereupon
the demised premises shall be taken or occupied by someone other than Tenant; or
if this lease be rejected under Section 235 of Title 11 of the U.S. Code
(bankruptcy code); or if Tenant shall fail to move into or take possession of
the premises within fifteen (15) days after the commencement of the term of this
lease, then, in any one or more of such events, upon Owner serving a written
five (5) days notice upon Tenant specifying the nature of said default and upon
the expiration of said five (5) days, if Tenant shall have failed to comply with
or remedy such default, or if the said default or omission complained of shall
be of a nature that the same cannot be completely cured or remedied within said
five (5) day period, and if Tenant shall not have diligently commenced curing
such default within such five (5) day period, and shall not thereafter with
reasonable diligence and in good faith, proceed to remedy or cure such default,
then Owner may serve a written three (3) days' notice of cancellation of this
lease upon Tenant, and upon the expiration of said three (3) days this lease and
the term thereunder shall end and expire as fully and completely as if the
expiration of such three (3) day period were the day herein definitely fixed for
the end and expiration of this lease and the term thereof and Tenant shall then
quit and surrender the demised premises to Owner but Tenant shall remain liable
as hereinafter provided.

          (2)  If the notice provided for in (1) hereof shall have been given,
and the term shall expire as aforesaid; or if Tenant shall make default in the
payment of the rent reserved herein or any item of additional rent herein
mentioned or any part of either or in making any other payment herein required;
then and in any of such events Owner may upon notice, re-enter the demised
premises either by force or otherwise, and dispossess Tenant by summary
proceedings or otherwise, and the legal representative of Tenant or other
occupant of demised premises and remove their effects and hold the premises as
if this lease had not been made. If Tenant shall make default hereunder prior to
the date fixed as the commencement of any renewal or extension of this lease,
Owner may cancel and terminate such renewal or extension agreement by written
notice.

REMEDIES OF OWNER AND WAIVER OF REDEMPTION

          18.  In case of any such default, re-entry, expiration and/or
dispossess by summary of proceedings or otherwise, (a) the rent shall become due
thereupon and be paid up to the time of such re-entry, dispossess and/or
expiration, (b) Owner may re-let the premises or any part or parts thereof,
either in the name of Owner or otherwise, for a term or terms, which may at
Owner's option be less than or exceed the period which would otherwise have
constituted the balance of the term of this lease and may grant concessions or
free rent or charge a higher rental than that in this lease, and/or (c) Tenant
or the legal representatives of Tenant shall also pay Owner as liquidated
damages for the failure of Tenant to observe and perform said Tenant's covenants
herein contained, any deficiency between the rent hereby reserved and/or
convenanted to be paid and the net amount, if any, of the rents collected on
account of the lease or leases of the demised premises for each month of the
period which would otherwise have constituted the balance of the term of this
lease. The failure of Owner to re-let the premises or any part or parts thereof
shall not release or affect Tenant's liability for damages. In computing such
liquidated damages there shall be added to the said deficiency such reasonable,
customary and ordinary expenses as Owner may incur in connection with 
re-letting, such as legal expenses, attorneys' fees, brokerage, advertising and
for keeping the demised premises in good order or for preparing the same for 
re-letting. Any such liquidated damages shall be paid in monthly installments by
Tenant on the rent day specified in this lease and any suit brought to collect
the amount of the deficiency for any month shall not prejudice in any way the
rights of Owner to collect the deficiency for any subsequent month by a similar
proceeding. Owner, in putting the demised premises in good order or preparing
the same for re-rental may, at Owner's option, make such alterations, repairs,
replacements, and/or decorations in the demised premises as Owner, in Owner's
sole judgment, considers advisable and necessary for the purpose of re-letting
the demised premises, and the making of such alterations, repairs, replacements,
and/or decorations shall not operate or be construed to release Tenant from
liability hereunder as aforesaid. Owner shall in no event be liable in any way
whatsoever for failure to re-let the demised premises, or in the event that the
demised premises are re-let, for failure to collect the rent thereof under such
re-letting, and in no event shall Tenant be entitled to receive any excess, if
any, of such net rents collected over the sums payable by Tenant to Owner
hereunder. In the event of a breach or
<PAGE>
 
threatened breach by Tenant of any of the covenants or provisions hereof, Owner 
shall have the right of injunction and the right to invoke any remedy allowed at
law or in equity as if re-entry, summary proceedings and other remedies were not
herein provided for. Mention in this lease of any particular remedy, shall not 
preclude Owner from any other remedy, in law or in equity. Tenant hereby 
expressly waives any and all rights of redemption granted by or under any 
present or future laws in the event of the Tenant being evicted or dispossessed 
for any cause, or in the event of Owner obtaining possession of demised 
premises, by reason of the violation by Tenant of any of the covenants and 
conditions of this lease, or otherwise.

FEES AND EXPENSES

          19.  If Tenant shall default in the observance or performance of any 
term or covenant on Tenant's part to be observed or performed under or by virtue
of any of the terms or provisions in any article of this lease, then, unless 
otherwise provided elsewhere in this lease. Owner may immediately or at any time
thereafter and without notice perform the obligation of Tenant thereunder. If 
Owner, in connection with the foregoing or in connection with any default by 
Tenant in the covenant to pay rent hereunder, makes any expenditures or incurs 
any obligations for the payment of money, including but not limited to 
reasonable attorney's fees, in  instituting, prosecuting or defending any action
or proceeding, then Tenant will reimburse Owner for such sums so paid or 
obligations incurred with interest and costs. The foregoing expenses incurred by
reason of Tenant's default shall be deemed to be additional rent hereunder and 
shall be paid by Tenant to Owner within five (5) days of rendition of any bill 
or statement to Tenant therefor. If Tenant's lease term shall have expired at 
the time of making of such expenditures or incurring of such obligations, such 
sums shall be recoverable by Owner as damages.

BUILDING ALTERATIONS AND MANAGEMENT

          20.  Owner shall have the right at any time without the same 
constituting an eviction and without incurring liability to Tenant therefor to 
change the arrangement and/or location of public entrances, passageways, doors, 
doorways, corridors, elevators, stairs, toilets or other public parts of the 
building and to change the name, number or designation by which the building may
be known. There shall be no allowance to Tenant for diminution of rental value 
and no liability on the part of Owner by reason of inconvenience, annoyance or 
injury to business arising from Owner or other Tenants making any repairs in the
building or any such alterations, additions and improvements. Furthermore, 
Tenant shall not have any claim against Owner by reason of Owner's imposition 
of such controls of the manner of access to the building by Tenant's social or 
business visitors as the Owner may deem necessary for the security of the 
building and its occupants.

NO REPRESENTATIONS BY OWNER

          21.  Neither Owner nor Owner's agents have made any representations or
promises with respect to the physical condition of the building, the land upon 
which it is erected or the demised premises, the rents, leases, expenses of 
operation or any other matter or thing affecting or related to the premises 
except as herein expressly set forth and no rights, easements or licenses are 
acquired by Tenant by implications or otherwise except as expressly set forth in
the provisions of this lease. Tenant has inspected the building and the demised 
premises and is thoroughly acquainted with their condition and agrees to take
the same "as is" and acknowledges that the taking of possession of the demised
premises by Tenant shall be conclusive evidence that the said premises and the
building of which the same form a part were in good and satisfactory condition
at the time such possession was so taken, except as to latent defects. All
understandings and agreements heretofore made between the parties hereto are
merged in this contract, which alone fully and completely expresses the
agreement between Owner and Tenant and any executory agreement hereafter made
shall be ineffective to change, modify, discharge or effect an abandonment of
it in whole or in part, unless such executory agreement is in writing and
signed by the party against whom enforcement of the change, modification,
discharge or abandonment is sought.

END OF TERM

          22.  Upon the expiration or other termination of the term of this 
lease, Tenant shall quit and surrender to Owner the demised premises, broom 
clean, in good order and condition, ordinary wear and damages which Tenant is 
not required to repair as provided elsewhere in this lease excepted, and Tenant 
shall remove all its property. Tenant's obligation to observe or perform this 
covenant shall survive the expiration or other termination of this lease. If the
last day of the term of this Lease or any renewal thereof, falls on Sunday, this
lease shall expire at noon on the preceding Saturday unless it be a legal
holiday in which case it shall expire at noon on the preceding business day.

QUIET ENJOYMENT

          23.  Owner covenants and agrees with Tenant that upon Tenant paying 
the rent and additional rent and observing and performing all the terms, 
covenants and conditions, on Tenant's part to be observed and performed, Tenant 
may peaceably and quietly enjoy the premises hereby demised, subject, 
nevertheless, to the terms and conditions of this lease including, but not 
limited to, Article 31 hereof and to the ground leases, underlying leases and 
mortgages hereinbefore mentioned.

FAILURE TO GIVE POSSESSION

          24.  If Owner is unable to give possession of the demised premises on 
the date of the commencement of the term hereof, because of the holding-over or 
retention of possession of any tenant, undertenant or occupants or if the 
demised premises are located in a building being constructed, because such 
building has not been sufficiently completed to make the premises ready for 
occupancy or because of the fact that a certificate of occupancy has not been 
procurred or for any other reason, Owner shall not be subject to any liability 
for failure to give possession on said date and the validity of the lease shall 
not be impaired under such circumstances, nor shall the same be construed in any
wise to extend the term of this lease, but the rent payable hereunder shall be 
abated (provided Tenant is not responsible for Owner's inability to obtain 
possession) until after Owner shall have given Tenant written notice that the 
premises are substantially ready for Tenant's occupancy. If permission is given 
to Tenant to enter into the possession of the demised premises or to occupy 
premises other than the demised premises prior to the date specified as the 
commencement of the term of this lease, Tenant covenants and agrees that such 
occupancy shall be deemed to be under all the terms, covenants, conditions and 
provisions of this lease, except as to the covenant to pay rent. Notwithstanding
anything to the contrary contained in this Article 24, in the event the 
Commencement Date (as hereinafter defined) does not occur within one hundred 
eighty (180) days after the Estimated Commencement Date (as hereinafter defined)
("Outside Date"), Tenant shall have a singe option to cancel this Lease and the 
term thereof by giving notice to Owner of such cancellation within ten (10) 
days, time being of the essence, next following the Outside Date, as said 
Outside Date may be extended pursuant to the following provisions. Upon the 
giving of such notice, this lease and the term thereof shall expire and come to 
an end as of the date of the giving of such notice and Tenant shall then quit 
and surrender the demised premises to Owner but Tenant shall remain liable as 
provided in the Lease. If Tenant shall fail to give timely notice exercising the
foregoing option to cancel this Lease and the term thereof, then the term shall 
commence and end in accordance with the provisions of this Lease. Owner shall 
have the right to extended the Outside Date by a period equal to the aggregate 
number of days of delay in Substantial Completion (as hereinafter defined) or in
the issuance of a temporary or permanent Certificate of Occupancy covering the 
demised premises occasioned by reason of Tenant's failure to cooperate with 
Owner, Tenant's delays in submitting any drawings or specifications, or in 
supplying information, or in approving drawings, specifications or estimates, or
in giving authorizations, or by reason of any "Extra" or "Change Order"
designated by Tenant, or by reason of any changes by Tenant in any designations
previously made by Tenant, or by reason of any similar acts or omissions of
Tenant or by reason of any cause or factor beyond Landlord's reasonable control
including but not limited to, strikes or other labor disputes, accidents, orders
or regulations of any Federal, State, County or Municipal authority, lack of
availability of materials, parts or utility services, delays due to adjustment
of insurance claims, acts of God, fire, earthquake, floods, explosion, action of
the elements, war, hostilities, invasion, insurrection, riot, mob violence,
sabotage or by reason of any other cause, whether similar or not to the
foregoing that is beyond the reasonable control of Owner. If Tenant shall use or
occupy all or part of the demised premises, the foregoing option to cancel this
Lease and the term thereof shall no longer be of any force and effect.

NO WAIVER

          25.  The failure of Owner to seek redress for violation of, or to 
insist upon the strict performance of any covenant or condition of this lease or
of any of the Rules or Regulations set forth or hereafter adopted by Owner,
shall not prevent a subsequent act which would have originally consituted a
violation from having all the force and effect of an original violation. The
receipt by Owner of rent with knowledge of the breach of any coventant of this
lease shall not be deemed a waiver of such breach and no provision of this lease
shall be deemed to have been waived by Owner unless such waiver be in writing
signed by Owner. no payment by Tenant or receipt by Owner of a lessor amount
than the monthly rent herein stipulated shall be deemed to be other than on
account of the earliest stipulated rent, nor shall any endorsement or statement
of any check or any letter accompanying any check or payments as rent be deemed
an accord and satisfaction, and Owner may accept such check or payments without
prejudice to Owner's rights to recover the balance of such rent or pursue any
other remedy in this lease provided. No act or thing done by Owner or Owner's
agents during the term hereby demised shall be deemed an acceptance of a
surrender of said premises, and no agreement to accept such surrender shall be
valid unless in writing signed by Owner, No employee of Owner or Owner's agent
shall have any power to accept the keys of said premises prior to the
termination of the lease and the delivery of keys to any such agent or employee
shall not operate as a termination of the lease or a surrender of the premises.

WAIVER OF TRIAL BY JURY

          26.  It is natually agreed by and between Owner and Tenant that the 
respective parties hereto shall and they hereby do waive trial by jury in any 
action, proceeding or counterclaim brought by either of the parties hereto 
against the other (except for personal injury or property damage) on any matters
whatsoever arising out of in any way connected with this lease, the relationship
of Owner and Tenant, Tenant's use of or occupancy of said premises, and any 
emergency statutory or any other statutory remedy. It is further matually agreed
that in the event Owner commences any summary proceeding for possession of the
premises, Tenant will not interpose any counterclaim of whatever nature or
decription in any such proceeding, including a counterclaim under Article 4;
provided, however, that Tenant shall be entitled to interpose any mandatory
<PAGE>
 
counterclaim which would otherwise be barred pursuant to the entire controversy 
doctrine.

INABILITY TO PERFORM         

          27.  This Lease and the obligation of Tenant to pay rent hereunder and
perform all of the other covenants and agreements hereunder on part of Tenant to
be performed shall in no wise be affected, impaired or excused because Owner is
unable to fulfill any of its obligations under this lease or to supply or is
delayed in supplying any service expressly or impliedly to be supplied or is
unable to make, or is delayed in making any repair, additions, alterations or
decorations or is unable to supply or is delayed in supplying any equipment or
fixtures if Owner is prevented or delayed from so doing by reason of strike or
labor troubles or any cause whatsoever including, but not limited to, government
preemption in connection with a National Emergency or by reason of any rule,
order or regulation of any department or subdivision thereof of any government
agency or by reason of the conditions of supply and demand which have been or
are affected by war or other emergency.

BILLS AND NOTICES             

          28.  See Article 57 Rider to Lease.

Services Provided by Owner   

          29.  As long as Tenant is not in default under any of the covenants of
this Lease, Owner shall provide: (a) necessary elevator facilities on business
days from 8 a.m. to 6 p.m. and have one elevator subject to call at all other
times; (b) heat to the demised premises when and as required by law, on business
days from 8 a.m. to 6 p.m.; (c) water for ordinary lavatory purposes, but if
Tenant uses or consumes water for any other purposes or in unusual quantities
(of which fact Owner shall be the sole judge), Owner may install a water meter
at Tenant's expense which Tenant shall thereafter maintain a Tenant's expense in
good working order and repair to register such water consumption and Tenant
shall pay for water consumed as shown on said meter as additional rent as and
when bills are rendered; (d) cleaning service for the demised premises on
business days at Owner's expense provided that the same are kept in order by
Tenant. If, however, said premises are to be kept clean by Tenant, it shall be
done at Tenant's sole expense, in a manner satisfactory to Owner and no one
other than persons approved by Owner shall be permitted to enter said premises
or the building of which they are a part for such purpose. Tenant shall pay
Owner the cost of removal of any of Tenant's refuse and rubbish from the
building; (e) if the demised premises are serviced by Owner's air
conditioning/cooling and ventilating system, air conditioning/cooling will be
furnished to tenant from May 15th through September 30th on business days
(Mondays through Fridays, holidays excepted) from 8:00 a.m. to 6:00 p.m., and
ventilation will be furnished on business days during the aforesaid hours except
when air conditioning/cooling is being furnished as aforesaid. If Tenant
requires air conditioning/cooling or ventilation for more extended hours or on
Saturdays, Sundays or on holidays, Owner will furnish the same as Tenant's
expense; (f) Owner reserves the right to stop services of the heating,
elevators, plumbing, air-conditioning, power systems or cleaning or other
services, if any, when necessary by reason of accident or for repairs,
alterations, replacements or improvements necessary or desirable in the judgment
of Owner for as long as may be reasonably required by reason thereof. If the
building of which the demised premises are a part supplies manually operated
elevator service, Owner at any time may substitute automatic control elevator
service and upon ten days' written notice to Tenant, proceed with alterations
necessary therefor without in any wise affecting this Lease or the obligation of
Tenant hereunder. The same shall be done with minimum of inconvenience to Tenant
and Owner shall pursue the alteration with due diligence.

CAPTIONS                      

          30.  The Captions are inserted only as a matter of convenience and for
reference and in no way define, limit or describe the scope of this lease nor
the intent of any provisions thereof.

DEFINITIONS             

          31.  The term "office", or "offices", wherever used in this lease,
shall not be construed to mean premises used as a store or stores, for the sale
or display, at any time, of goods, wares or merchandise, of any kind, or as a
restaurant, shop, booth, bootblack or other stand, barber shop, or for other
similar purposes or for manufacturing. The term "Owner" means a landlord or
lessor, and as used in this lease means only the owner, or the mortgagee in
possession, for the time being of the land and building (or the owner of a lease
of the building or of the land and building) of which the demised premises form
a part, so that in the event of any sale or sales of said land and building or
of said lease, or in the event of a lease of said building, or of the land and
building, the said Owner shall be and hereby is entirely freed and relieved of
all covenants and obligations of Owner hereunder, and it shall be deemed and
construed without further agreement between the parties or their successors in
interest, or between the parties and the purchaser, at any such sale, or the
said lessee of the building, or of the land and building, that the purchaser of
the lessee of the building has assumed and agreed to carry out any and all
covenants and obligations of Owner, hereunder. The words "re-enter" and 
"re-entry" as used in this lease are not restricted to their technical legal
meaning. The term "business days" as used in this lease shall exclude Saturdays
(except such portion thereof as is covered by specific hours in Article 29
hereof), Sundays and all days set forth on Exhibit E.

ADJACENT EXCAVATION-SHARING   

          32.  Intentionally Deleted Prior to Execution.

RULES AND REGULATIONS         

          33.  Tenant and Tenant's servants, employees, agents, visitors, and
licensees shall observe faithfully, comply strictly with, the written Rules and
Regulations and such other and further reasonable written Rules and Regulations
as Owner or Owner's agents may from time to time adopt. Notice of any additional
rules or regulations shall be given in such manner as Owner may elect. In case
Tenant disputes the reasonableness of any additional Rule or Regulation
hereafter made or adopted by Owner or Owner's agents, the parties hereto agree
to submit the question of the reasonableness of such Rule or Regulation for
decision to the Newark office of the American Arbitration Association, whose
determination shall be final and conclusive upon the parties hereto. The right
to dispute the reasonableness of any additional Rule or Regulation upon Tenant's
part shall be deemed waived unless the same shall be asserted by service of a
notice, in writing upon Owner within ten (10) days after the receipt of notice
thereof. Nothing in this lease contained shall be construed to impose upon Owner
any duty or obligations to enforce the Rules and Regulations or terms, covenants
or conditions in any other lease, as against any other tenant and Owner shall
not be liable to Tenant for violation of the same by any other tenant, its
servants, employees, agents, visitors or licensees.

SECURITY                      

          34. Tenant shall deposit with Owner on the date hereof the sum of
$17,504.38 as security for the faithful performance and observance by Tenant of
the terms, provisions and conditions of this lease; it is agreed that in the
event Tenant defaults in respect of any of the terms, provisions and conditions
of this lease, including, but not limited to, the payment of rent and additional
rent. Owner may use, apply or retain the whole or any part of the security so
deposited to the extent required for the payment of any rent and additional rent
or any other sum as to which Tenant is in default or for any sum which Owner may
expend or may be required to expend by reason of Tenant's default in respect of
any of the terms, covenants and conditions of this lease, including but not
limited to, any damages or deficiency in the re-letting of the premises, whether
such damages or deficiency accrued before or after summary proceedings or other
re-entry by Owner. In the event that Tenant shall fully and faithfully comply
with all of the terms, provisions, covenants and conditions of this lease, the
security shall be returned to Tenant after the date fixed as the end of the
Lease and after delivery of entire possession of the demised premises to Owner.
In the event of a sale of the land and building or leasing of the building, of
which the demised premises form a part, Owner shall have the right to transfer
the security to the vendee or lessee and Owner shall thereupon be released by
Tenant from all liability for the return of such security; and Tenant agrees to
look to the new Owner solely for the return of said security, and it is agreed
that the provisions hereof shall apply to every transfer or assignment made of
the security to a new Owner. Tenant further covenants that it will not assign or
encumber or attempt to assign or encumber the monies deposited herein as
security and that neither Owner nor its successors or assigns shall be bound by
any such assignment, encumbrance, attempted assignment or attempted
encumbrance.

ESTOPPEL CERTIFICATE          

          35.  Tenant, at any time, and from time to time, upon at least 10
days' prior notice by Owner, shall execute, acknowledge and deliver to Owner,

Revaluation, and the Base Tax Rate shall be as defined in Section 36.1(2) above,
or

          (b)   The Assessed Valuation shall be the actual amount assessed, and
the Base Tax Rate shall be the real estate tax rate as subsequently reduced by
the taxing jurisdiction in connection with the Revaluation.

          Landlord shall inform the Tenant as to which of the above two methods
Landlord has elected at such time as Landlord submits the Tax Statement to 
Tenant.

          36.5  Building Operating Costs. (1) Tenant hereby agrees that for each
Operating Year during the term of this Lease for which the total Building
Operating costs (as hereinafter defined) shall exceed the Building Operating

annual payment due on the succeeding Billing Date.

expense incurred in connection with the ownership, administration, management,

<PAGE>

     (5)  Anything to the contrary contained in this Article 36 notwithstanding,
if the average occupancy of the Building is less than ninety-five (95%) percent 
during the First Operating Year, then Landlord shall make a determination 
("Landlord's Determination") of what the Building Operating Costs for such year 
would have been if during the entire year the average tenant occupancy of the 
Building were ninety-five (95%) percent. Landlord's Determination shall be 
binding and conclusive upon Tenant and shall for all purposes of this Lease be 
deemed to be the Building Operating Costs for the First Operating Year. Landlord
shall notify Tenant of Landlord's Determination within ninety (90) days
following the last day of the First Operating Year. Thereafter, if for any
subsequent Lease year the average tenant occupancy of the Building is below
ninety-five (95%), the Building Operating Costs for any such year shall be
adjusted by Landlord to the amount that such Building Operating Costs would have
been if the average tenant occupancy during that year has been ninety-five (95%)
percent.

          36.6 If, pursuant to any Tax Statement or Operating Statement showing 
Taxes or Building Operating Costs for any year subsequent to the First Tax Year 
or First Operating Year, respectively, there shall be an additional amount 
payable or a refund due with respect to Taxes and/or Building Operating Costs 
for the period covered by such statement(s), such amount shall be calculated, 
and any amount payable by the Tenant to the Landlord as additional rent shall be
promptly paid, or the amount due to the Tenant shall be credited against amounts
owing Landlord. However, it is agreed by the parties that any refund shall not 
in any way operate to reduce the Minimum Rent. If such calculation takes place 
and/or any payment in connection herewith becomes payable after the expiration 
of the term of this Lease, this provision shall be deemed to have survived such 
expiration.

          36.7 Any increase in additional rent under this Article shall be 
prorated for the final Operating Year if such Operating Year covers a period of 
less than twelve (12) full months. Tenant's obligation to pay additional rent 
under this Article for the final Operating Year shall survive the expiration of 
the term of this Lease.

          36.8 In the event that the payment of any sum required to be paid by
Tenant to Landlord under this Lease (including without limiting the generality
of the foregoing, Minimum Rent, Adjusted Minimum Rent, or payment made by
Landlord under any provision of this Lease for which Landlord is entitled to
reimbursement by Tenant) shall become overdue for 10 days beyond the date on
which they are due and payable as provided in this Lease, then a delinquency
service charge equal to four percent of the amount overdue shall become
immediately due and payable to Landlord as liquidated damages for Tenant's
failure to make prompt payment. Further, such delinquency service charge shall
be payable on the first day of the month next succeeding the month during which
such late charges become payable as additional rent, together with interest at
the maximum rate permitted by law on the amounts overdue from the date on which
they became due and payable. In the event of nonpayment of any delinquency
service charges and interest provided for above, Landlord shall have, in
addition to all other rights and remedies, all the rights and remedies provided
for herein and by law in the case of nonpayment of rent. No failure by Landlord
to insist upon the strict performance by Tenant of Tenant's obligations to pay
late charges shall constitute a waiver by Landlord of its rights to enforce the
provisions of this Section

                                       4

36.8 in any instance thereafter occurring. The provisions of this Section 36.8 
shall not be construed in any way to extend any time period provided for in this
Lease.

          36.9 If Tenant fails to remit when due any sum required to be paid by 
Tenant to Landlord under this Lease (including, without limiting the generality 
of the foregoing, Minimum Rent, Adjusted Minimum Rent, or payment made by 
Landlord under any provision of this Lease for which Landlord is entitled to 
reimbursement by Tenant), Landlord may, in addition to all other rights and 
remedies provided herein and by law, serve a written notice of cancellation of 
this Lease upon Tenant and if Tenant fails to cure the applicable default or 
defaults within ten (10) days after receipt of the above-referenced notice, this
Lease and the term thereof shall terminate and expire as fully and completely as
if the day on which said notice of cancellation was given were the day herein 
definitely fixed for the end and expiration of this Lease and the term thereof 
and Tenant shall then quit and surrender the Demised Premises to Landlord but 
Tenant shall remain liable as herein provided. Following each second 
consecutive monthly installment of Adjusted Minimum Rent that remains unpaid for
longer than ten (10) days beyond the date on which same is due and payable, 
Landlord may, in addition to all other rights and remedies provided herein and 
by law, require that (i) beginning with the first monthly installment of 
Adjusted Minimum Rent next due, the Adjusted Minimum Rent shall no longer be 
paid in monthly installments but shall be payable in advance on a quarterly 
basis and/or (ii) Tenant increase the amount of the security deposited with 
Landlord by an amount equal to two (2) months' Minimum Rent. If Tenant shall 
deliver to Landlord a check that is returned unpaid for any reason, Tenant shall
pay Landlord TWENTY FIVE AND 00/100 DOLLARS ($25.00) for Landlord's expense in 
connection therewith and said charge shall be payable to Landlord on the first 
day of the next succeeding month as additional rent.

               ESTIMATED COMMENCEMENT DATE AND TERMINATION DATE
               ------------------------------------------------

          37.1 The parties intended that the Lease shall commence on or about 
February 25, 1994 (the "Estimated Commencement Date"). Notwithstanding the 
above, the commencement date ("Commencement Date") as defined, fixed and 
ascertained in this Article shall be the date upon which the work required to be
performed by the Landlord pursuant to the Work Letter attached hereto a Exhibit 
"B" (the "Work"), shall be substantially completed. The Work shall be deemed to 
be substantially completed ("Substantial Completion") for all purposes 
hereunder, on the earlier of the date upon which:

          A.   (i) Landlord has procured a temporary or permanent Certificate of
Occupancy, permitting occupancy of the Demised Premises by the Tenant ; and (ii)
the Landlord's architects shall have certified that Landlord has substantially 
performed the Work. Substantial Completion shall be deemed to have occurred even
though minor details of work remain to be done, provided such details do not
materially interfere with the Tenant's use of the Demised Premises,

                                      or

          B.   Tenant shall have taken possession of all or any part of the 
Demised Premises.

          37.2 On or about the Commencement Date, Landlord shall deliver to 
Tenant a notice ("Commencement Date Notice") fixing the Commencement Date and 
termination date which shall be a date six (6) years after the Commencement 
Date ("Termination Date"). Tenant shall acknowledge receipt of the Commencement 
Date Notice by signing a copy of same and returning it to Landlord within five 
(5) days of the receipt thereof.

          37.3 The date upon which Tenant's obligation to pay Minimum Rent due 
hereunder commences ("Rent Commencement Date") shall be deemed to be three (3) 
months after the Commencement Date. Notwithstanding the foregoing, Tenant shall 
pay Landlord upon the 

                                       5

<PAGE>
 
execution of this Lease the first monthly installment of Minimum Rent and the
security referred to in Articles 34 and 62 hereof.

          37.4 If, prior to the Commencement Date, Tenant shall enter the 
Demised Premises to make any installations of its equipment, fixtures and
furnishings, Landlord shall have no liability for any personal injury or
property damage suffered by Tenant.

          37.5 Anything contained in this Article 37 to the contrary
notwithstanding, if for any reason the Premises are not ready for occupancy on
the Estimated Commencement Date, this Lease shall nevertheless continue in full
force and effect; the Commencement Date shall be postponed until Substantial
Completion has occurred and the Rent Commencement Date shall be postponed for a
like number of days, subject to Article 64. The Termination Date shall be 
adjusted to provide the full term set forth above.

          38.  TENANT'S POSSESSION
               -------------------

          38.1 When Tenant takes possession of the Demised Premises, Tenant 
shall be deemed to have accepted the Demised Premises as substantially completed
as of the date of such possession, subject to Tenant's punch-list items.

          39.  HEATING, AIR-CONDITIONING AND VENTILATION;
               LEGAL HOLIDAYS; "AFTER HOURS"
               ------------------------------------------

          39.1 Notwithstanding the provisions of subsections (b) and (e) of
Article 29 of this Lease , but subject to all of the other terms, covenants and 
conditions of said Article 29, Landlord shall provide and furnish appropriate 
heat, air-conditioning or ventilation to the Demised Premises between the hours 
of 8:00 a.m. to 6:00 p.m., Monday through Friday, other than Legal Holidays 
(which are listed on Exhibit "E"), attached to this Lease. The heat, 
air-conditioning or ventilation supplied to the Demised Premises shall be 
consistent with other similarly situated office buildings in the Parsippany-Troy
Hills area.

          39.2 At all other times not otherwise provided for in Section 39.1 
above, Landlord agrees that it shall, upon prior written request from Tenant, 
provide after-hours air-conditioning, ventilation or heating, as the case may 
be, for which Tenant shall pay to Landlord as additional rent hereunder, a sum 
equal to $50.00 per hour for providing heat, air-conditioning or ventilation 
(irrespective of whether any other tenants in the Building are furnished with 
heat, air-conditioning or ventilation at the same time) that being intended to 
cover Landlord's cost for the power or fuel required to provide the same. In the
event that during the term of this Lease, or any renewal hereof, the Landlord's 
cost for providing after-hours heating, air-conditioning or ventilation shall 
increase by virtue of utility rate increases or unit fuel cost increases, the 
above-specified hourly charges shall be adjusted from time to time to reflect 
said increases. In addition to the foregoing, should there be any charges 
incurred by Landlord for additional attendant engineers or similar additional 
requirements as may be imposed from time to time by the State Labor Department, 
local authorities, union requirements, or the like, Tenant agrees to reimburse 
Landlord for its out-of-pocket expenses incurred in connection therewith, 
related to the after-hours use by Tenant.

          40.  ELECTRIC CURRENT
               ----------------

          40.1 Landlord's obligation to supply current shall be limited to the 
current required to power the Building standard heating and air-conditioning 
systems and the lighting of common areas.

          40.2 Tenant shall arrange to purchase and pay for all of the electric 
current requirements for light and power used in connection with Tenant's 
operations within the Demised Premises. Landlord shall furnish and install an 
electric meter for the 

                                       6
<PAGE>
 
measurement of the consumption of Tenant's electric current as herein provided.

          40.3  At the request of Landlord prior to the occupancy of the Demised
Premises, Tenant shall execute any and all applications for service, or forms 
required by the local utility company supplying electric current to the Building
for the metering of all electric current and power required for the operation 
of the electrical equipment of any nature whatsoever and lights within or 
serving the Demised Premises.

          40.4  Tenant's electric consumption within the Demised Premises shall 
be measured by a separate electric meter within the Demised Premises. Tenant 
shall pay its own electric costs directly to the utility company serving the 
Demised Premises and the provisions of Sections 40.1 and 40.2 shall thereupon 
apply hereunder.

          41.   LIABILITY INSURANCE
                -------------------

          41.1  Tenant, at its sole cost and expense, shall procure, provide and

managing agent of the Building as additional insureds and shall protect Landlord
in respect of claims by Tenant as if Landlord were separately insured; and (2)
insurance against such other perils and in such amounts as may be required by
law upon not less than thirty (30) days' prior written notice.

          41.2  Each of the aforesaid policies shall contain an undertaking by 
the insurer that no material change adverse to Landlord or Tenant will be made 
and such policy will not lapse or be cancelled, except after not less than 
thirty (30) days' prior written notice to Landlord of the intended change, lapse
or cancellation. On or before the Commencement Date and thereafter, at least 
thirty (30) days prior to the effective date of any policy, Tenant agrees to 
deliver to Landlord a duplicate original of the aforesaid policies.

          42.   ALL RISK INSURANCE

personal property, equipment and improvements. Such insurance shall include 
Landlord and the managing agent of the Building as additional insureds and shall
protect Landlord in respect of claims by Tenant as if Landlord were separately 
insured. The aforesaid "All Risk" policy shall contain an undertaking by the 
insurer that no material change adverse to Landlord or Tenant will be made and 
such policy will not lapse or be cancelled, except after not less than ninety 
(90) days' prior written notice to Landlord of the intended change, lapse, or 
cancellation. On or before the Commencement Date and thereafter, at least thirty
(30) days prior to the effective date of the "All

                                       7
<PAGE>
 
Risk" policy, Tenant agrees to deliver to Landlord a duplicate original of said 
policy.

          42.B  LANDLORD'S INSURANCE
                --------------------

          42B.1 Throughout the term of this Lease, Landlord shall maintain in 
full force and effect a comprehensive liability policy and an all risk insurance
policy for the full replacement value of the Building.

          43.   PARKING FACILITIES
                ------------------

          43.1  So long as Tenant is not in default under this Lease, Landlord 
hereby grants to Tenant the revocable license (the "License") to park up to 
forty eight (48) cars ("Allotted Parking"), for use solely by Tenant and 
Tenant's employees, licensees, guests and invitees in the parking area or areas 
serving the Building (the "Parking Area"). Landlord agrees to mark once, at 
Tenant's expense, as the designated parking spaces of Tenant four (4) parking 
spaces within the Parking Area. Such designations shall not increase the 
Allotted Parking defined in the first sentence of this Section. The use of any
more than the Allotted Parking by Tenant, its employees, licensees, guests or 
invitees, after notice from Landlord at least two (2) times during any calender 
year, shall be deemed a material event of default under this Lease, and Landlord
may immediately suspend or revoke the License, remove Tenant's designations from
any parking spaces so marked and/or exercise such remedies as are provided in 
this Lease. Landlord shall not be responsible to Tenant (i) if Tenant's 
designated parking spaces are used by anyone other than Tenant, its employees, 
licensees, guests and invitees, (ii) for enforcing the License or (iii) for 
violation of the License by other tenants of the Building, by third parties, or 
guests or visitors to the Building.

          43.2  In the event the number of parking spaces in the Parking Area is
reduced by circumstances beyond the control of Landlord, the Allotted Parking 
shall be reduced proportionately.

          43.3  Nothing contained in this Lease shall be deemed to create 
liability upon Landlord for any damage to motor vehicles of visitors or 
employees, for any loss of property from within those motor vehicles, or for any
injury to Tenant, its employees, licensees, guests and invitees unless 
ultimately determined to be caused by the sole negligence or willful misconduct 
of Landlord, its agents, servants and employees. Tenant agrees to acquaint its 
employees with any parking rules and regulations promulgated by Landlord and 
assumes responsibility for compliance by its employees with such parking 
provisions, and Tenant shall be liable to Landlord for all unpaid parking 
charges, if any, incurred by its employees. Any amount due from Tenant pursuant 
to this Article 43 shall be deemed additional rent and failure to pay same shall
constitute a default under the Lease. If Tenant or its employees, licensees, 
guests and invitees park illegally or in areas designated for use by others, or 
in driveways, fire lanes or areas not striped for general parking, then Landlord
may charge Tenant, as additional rent, FIFTY and 00/100 DOLLARS ($50.00) per 
day for each day or partial day each motor vehicle is so parked. In addition,
Tenant authorizes Landlord to (i) tow away from the Parking Area, at Tenant's
sole cost and expense, any motor vehicle belonging to Tenant or Tenant's
employees, licensees, guests and invitees parked illegally or in violation of
this Article 43 or any parking rules and regulations promulgated by Landlord
after notice to Tenant and (ii) attach violation stickers or notices to any
motor vehicles belonging to Tenant or Tenant's employees, licensees, guests and
invitees parked illegally or in violation of this Article 43 or any parking
rules and regulations promulgated by Landlord.

          44.   ACCESS AND COMMON AREAS
                -----------------------

          44.1  Tenant shall have the right of nonexclusive use, in common with 
others, of (a) automobile parking areas not designated for use by others and 
driveways (subject to Article 43 hereof); (b)

                                       8
<PAGE>
 
footways, and (c) such elevator and other facilities as may be constructed and
designated from time to time by Landlord in the Building, all to be subject to
the terms and conditions of the Lease and to reasonable rules and regulations
for the use thereof as prescribed from time to time by Landlord.

          45.   RELOCATION
                ----------

          45.1  If the Demised Premises contain less than 10,000 square feet of 
rentable area, Landlord shall have the right, at its option, upon at least sixty
(60) days' written notice to Tenant, to relocate Tenant and to substitute for
the Demised Premises other space within the office park of which the Building
forms a part containing at least as much rentable area as the Demised Premises
(the "Substitute Premises"). The Substitute Premises shall be improved by
Landlord at its expense, with decorations and improvements that are
substantially comparable in quantity and quality to those provided by Landlord
in the original Demised Premises. Landlord shall pay the expenses reasonably
incurred by Tenant in connection with such substitution, including but not
limited to costs of moving, door lettering and telephone relocation. The
Substitute Premises shall become the "Demised Premises" for purposes of this
Lease following Tenant's taking occupancy thereof.

          46.   BROKER
                ------

          46.1  Tenant and Landlord each represents to the other that no real 
estate broker other than Matthew Ray of Joseph Hilton & Associates is 
responsible for bringing about, or negotiating, this Lease and Tenant and 
Landlord have not dealt with any other broker in connection with the Demised 
Premises.

          46.2  In accordance with the foregoing representation, Tenant and 
Landlord each agrees to defend, indemnify and hold harmless the other, its 
affiliates and/or subsidiaries, partners and officers from any expense or 
liability (including attorney's fees) arising out of any claim for commission by
any broker other than Matthew Ray of Joseph Hilton & Associates claiming or 
alleging to have acted on behalf of or to have dealt with Tenant or Landlord, as
applicable. Landlord agrees to pay a commission to the broker for facilitating 
this transaction in accordance with a separate agreement between the Landlord 
and said broker.

          47.   CLEANING SERVICES
                -----------------

          47.1  So long as Tenant is not in default under this Lease, Landlord 
shall provide services for maintenance of the grounds, common areas and parking 
areas and such other cleaning services within the Demised Premises as are set 
forth on "Cleaning Services Rider" annexed hereto and made a part hereof as 
Exhibit "D", as same may be reasonably amended from time to time by Landlord.

          47.2  Tenant acknowledges that Landlord's obligation to cause the 
office areas of the Demised Premises to be cleaned excludes any portions of the 
Demised Premises which are inaccessible to Landlord or Landlord's cleaning 
contractor. Tenant shall pay to Landlord the cost of removal from the Demised 
Premises of any of Tenant's refuse or rubbish other than ordinary office waste, 
and Tenant, at Tenant's expense, shall cause all portions of the Demised
Premises not used as office areas to be cleaned daily in a manner satisfactory
to Landlord. Tenant also shall cause all portions of the Demised Premises used
for the storage, preparation, service or consumption of food or beverages to be
exterminated against infestation by vermin, roaches or rodents regularly and, in
addition, whenever there shall be evidence of any infestation. Tenant shall
contract directly with Landlord or, at Landlord's option, directly with
Landlord's contractors, for the removal of such other refuse and rubbish and for
cleaning services in addition to those furnished by Landlord and for
extermination services required hereunder.

          48.   ASSIGNMENT AND SUBLETTING
                -------------------------

          48.1  For purposes of this Article and Article 11, any occupancy 
arrangement (including without limitation management agreements, concessions and
licenses) affecting all or any part of the Demised Premises, other than a direct
lease with Landlord, not deemed an assignment shall be referred to as a sublease
and any occupant of all or part of the Demised Premises, other than a tenant 
under a direct lease with Landlord, not deemed an assignee shall be referred to 
as a sublessee. Supplementing the provisions of Article 11, and except as 
provided in section 48.8 if the Tenant shall desire to assign this Lease, sublet
or underlet all or any portion of the Demised Premises, it shall first submit in
writing to the Landlord a notice setting forth in reasonable detail:

          (a)   the identity and address of the proposed assignee or sublessee;

          (b)   in the case of a subletting, the terms and conditions thereof;

          (c)   the nature and character of the business of the proposed 
assignee and sublessee and its proposed use for the Demised Premises;

          (d)   evidence that the proposed assignee or sublessee is a United 
States citizen or citizens or a corporation qualified to do business in the 
State of New Jersey and organized and existing under the laws of one of the 
States of the United States;

proposed assignee or sublessee reasonably sufficient to enable Landlord to 
determine the proposed assignee's or sublessee's financial responsibility; and

          (f)   in the case of a subletting of only a portion of the Demised 
Premises, plans and specifications for Tenant's layout, partitioning, and 
electrical installations for the portion of the Demised Premises to be sublet.

          48.2  If the nature and character of the business of the proposed 
assignee or sublesse, and the proposed use and occupancy of the Demised 
Premises, or any portion thereof, by the proposed assignee or sublessee, is in 
keeping and compatible with the dignity and character of the Building, then, 
subject to compliance with the requirements of Article 11 and this Article 48, 
anything to the contrary in Article 11 notwithstanding, Landlord agrees not 
unreasonably to withhold or delay its consent to any such proposed assignment or
subletting; provided, however, that Tenant shall, by notice in writing as 
described in Section 48.1, advise Landlord of its intention to assign this Lease
or to sublease all or any part of the Demised Premises, from, on and after a 
stated date (which shall not be less than 60 days after the date of Tenant's 
notice), in which event Landlord shall have the right, to be exercised by giving
written notice, to recapture the space described in Tenant's notice. Such 
recapture notice shall, if given, cancel and terminate this Lease with respect 
to the space therein described as of a date which shall be the later of 30 days 
following the date set forth in Tenant's notice, or 30 days after Tenant shall 
have surrendered possession of the Demised Premises. In the event less than all 
of the Demised Premises are recaptured, Landlord shall construct and erect such 
partitioning and modify building systems as may be required to separate the 
space retained by Tenant from the space recaptured. The cost of such alterations
shall be borne by Landlord.

          48.3  If this Lease be cancelled pursuant to the foregoing with 
respect to less than the entire Demised Premises, the Minimum Rent and/or the 
Adjusted Minimum Rent and Tenant's Occupancy Percentage shall be adjusted on the
basis of the number of square feet retained by Tenant in proportion to the 
number of square feet originally demised under this Lease, and this Lease, as so
amended, shall continue thereafter in full force and effect.

                                      10
<PAGE>
 
          48.4  In addition to the foregoing requirements: (a) no sublease shall
violate any law or result in an occupancy of the Demised Premises by more than 
two tenants, including the Tenant hereunder, (b) no sublease shall be for a term
of less than two years, unless the unexpired term of this Lease shall be less 
than two years at the commencement of the sublease, (c) no assignee or sublessee
shall be an existing tenant of or any party then negotiating for space in the 
Building, or any other building in the office park of which the Building is a 
part (i) owned by Landlord, Bellemead Development Corporation ("Bellemead") or 
any partnership in which Bellemead or an affiliate of Bellemead is a partner or 
(ii) managed by Bellemead or an affiliate of Bellemead ("Affiliated Building"), 
(d) no sublease shall result in the occupancy of less than 1000 square feet of 
space, (e) Tenant shall not be in default under any of the terms and conditions 
of this Lease at the time of any notice or request for consent under the terms 
of this Article or at the effective date of such assignment or subletting, (f) 
no subletting or assignment shall be for a rental rate less than that currently 
being charged by Landlord for comparable space in the Building or any Affiliated
Building. Furthermore, anything to the contrary in Section 48.2 notwithstanding,
Landlord shall not consent to any sublease or assignment unless Tenant agrees at
the time of the proposed sublease or assignment and in the Tenant's notice
required in Section 48.2 to pay over to Landlord seventy-five (75%) percent of
all consideration (of whatever nature) that would be payable by the prospective
sublessee or assignee to Tenant over the term of the sublease or assignment
pursuant to such sublease or assignment which exceeds the prorata share of the
                                                          -------
Minimum Rent allocable to the Demised Premises, or any part thereof, as the case
may be, payable by Tenant hereunder and (g) Tenant shall pay when due all
brokerage or similar commissions arising from any assignment or sublease.

          48.5  Any sublease must provide (a) that it shall be subject and 
subordinate to all of the terms and conditions of this Lease, (b) that 
notwithstanding Article 2 hereof, the use of the Demised Premises thereunder 
shall be restricted exclusively to executive and administrative office use, (c) 
that the term thereof shall not extend beyond a date which is one day prior to 
the expiration date of the Term hereof, (d) no sublessee or its heirs, 
distributees, executors, administrators, legal representatives, successors or 
assigns, without the prior consent of Landlord in each instance, which consent 
Landlord may withhold for any reason or no reason, shall (i) assign, whether by 
merger, consolidation or otherwise, mortgage or encumber its interest in any 
sublease, in whole or in part, or (ii) sublet, or permit the subletting of, that
part of the Demised Premises affected by such subletting or any part thereof, or
(iii) permit such part of the Demised Premises affected by such subletting or 
any part thereof to be occupied or used for desk space, mailing privileges or 
otherwise, by any person other than such sublessee. The sale, pledge, transfer 
or other alienation of (y) any of the issued and outstanding capital stock of 
any corporate sublessee (unless such stock is publicly traded on any recognized 
security exchange or over-the-counter market) or (z) any transfer or interest in
any partnership or joint venture sublessee, however accomplished, and whether in
a single transaction or in a series of related or unrelated transactions, shall 
be deemed, for the purposes of this Section, an assignment of such sublease 
which shall require the prior consent of Landlord in each instance, and (e) in 
the event of cancellation or termination of this Lease for any reason whatsoever
or of the surrender of this Lease whether voluntary, involuntary or by operation
of law, prior to the expiration date of such sublease, including extensions and 
renewals granted thereunder, that, at Landlord's options, the subtenant shall 
vacate the Demised Premises or shall make full and complete attornment to 
Landlord for the balance of the term of the sublease, which attornment shall be 
evidenced by an agreement in form and substance satisfactory to Landlord which 
the subtenant shall execute and deliver at any time within five days after 
request by Landlord, its successors and assigns. The subtenant shall waive the 
provisions of any law now or hereafter in effect which may give the subtenant 
any right of election to terminate the sublease or to surrender possession of 
the Demised Premises in the event any proceeding is brought by Landlord to 
terminate this

Lease. No assignee or sublessee shall receive any credit from Landlord 
whatsoever for security deposits, rent or any other monies paid to Tenant unless
same shall have been actually received by Landlord.

assignment of this Lease and shall require the prior written consent of Landlord
in each instance:

          (a)   Any assignment or transfer of this Lease by operation of law;

          (b)   Any hypothecation, pledge or collateral assignment of this 
Lease;

          (c)   Any involuntary assignment or transfer of this Lease in 
connection with bankruptcy, insolvency, receivership or otherwise;

          (d)   Any assignment, transfer, disposition, sale or acquiring of a 
controlling interest in Tenant to or by any person, entity or group of related
persons or affiliated entities, whether in a single transaction or in a series
of related or unrelated transactions; and

          (e)   Any issuance of an interest or interests in Tenant (whether 
stock, partnership interests or otherwise) to any person, entity or group of 
related persons or affiliated entities, whether in a single transaction or in a 
series of related or unrelated transactions, such that following such issuance, 
such person, entity or group shall hold a controlling interest in Tenant.

For purposes of the immediately preceding sentence, a "controlling interest" of
Tenant shall mean fifty (50%) percent or more of the aggregate issued and 
outstanding equitable interest (whether stock, partnership interests or 
otherwise) thereof.

          48.7  Tenant, its sublessees, and their respective successors and 
assigns acknowledge and agree that the restriction that Landlord's consent under
certain circumstances to a proposed assignment of this Lease or to a subletting 
shall not be unreasonably withheld and shall not be intended or construed as an 
agreement or covenant on the part of Landlord, but rather as a qualification on 
Tenant's covenant not to assign this Lease or sublet, and they further agree 
that Landlord shall not be liable in damages or subject to liability of any 
other kind or nature whatever by reason of Landlord's failure or refusal to 
grant its consent to any proposed assignment of this Lease or subletting of the 
Demised Premises, the sole and exclusive recourse being a declaratory judgment 
on the question of Landlord's reasonableness.

          48.8  It is a condition to the effectiveness of any permitted 
assignment or sublease otherwise complying with Article 11 and this Article 48 
that the (i) Tenant increase on Landlord's demand the amount of security 
deposited with Landlord by a sum not to exceed two (2) months Adjusted Minimum 
Rent and (ii) assignee execute, acknowledge and deliver to Landlord an agreement
in form and substance satisfactory to Landlord whereby the assignee assumes all 
obligations of Tenant under this Lease, and agrees that the provisions of 
Article 11 and this Article 48 shall continue to be binding upon it in respect 
of all future assignments of this Lease. No assignment of this Lease shall 
release the assignor from its continuing obligations to Landlord under this 
Lease or any renewals or extensions thereof, except as expressly herein 
provided, and Tenant and any subsequent assignor shall continue to remain 
jointly and severally liable (as primary obligor) for all of Tenant's 
obligations hereunder.

          48.9  Tenant covenants to obtain all permits and approvals required by
any governmental or quasi-governmental agency for any work or otherwise required
in connection with any assignment of this Lease or any sublease, and Tenant
shall deliver copies of the same to Landlord prior to the commencement of work
if work is to be done. Tenant is furthermore responsible for and is

                                      12
<PAGE>
 
required to reimburse Landlord for all costs including, but not limited to, 
architectural, engineering and legal fees which Landlord incurs in reviewing any
proposed assignment of this Lease or any sublease and any permits, approvals and
applications for the construction within the Demised Premises.

          48.10 If Landlord reasonably withholds its consent of any proposed 
assignment or sublease, or if Landlord exercises its recapture option under 
Section 48.2, Tenant shall indemnify, defend and hold harmless Landlord against 
and from all loss, liability, damage, cost and expense (including reasonable 
attorneys' fees and disbursements) resulting from any claims that may be made 
against Landlord by the proposed assignee or sublessee or by any brokers or 
other persons claiming a commission or similar compensation in connection with 
the proposed assignment or sublease.

          48.11 If Landlord consents to any proposed assignment or sublease and 
Tenant fails to consummate the assignment or sublease to which Landlord 
consented within 45 days after the giving of such consent, Tenant shall be 
required again to comply with all of the provisions and conditions of this 
Article 48 before assigning this Lease or subletting all or part of the Demised 
Premises.

          48.12 The joint and several liability of the named Tenant and any 
immediate or remote successor in interest of the named Tenant for the due 
performance and observance of all covenants and conditions to be performed and 
observed by Tenant shall not be impaired by any agreement of Landlord extending 
the time for such performance or observance or by Landlord's waiving or failing 
to enforce any provisions of this Lease.

          48.13 The listing of any name other than that of Tenant on any door of
the Demised Premises or on any directory or in any elevator in the Building or 
otherwise, shall not operate to vest in the person so named any right or 
interest in this Lease or in the Demised Premises or the Building, or be deemed 
to constitute, or serve as a substitute for any prior consent required under 
this Article, and it is understood that any such listing shall constitute a 
privilege extended by Landlord which shall be revocable at Landlord's will by 
notice to Tenant.

          48.14 Any provisions of Article 11 and Article 48 to the contrary 
notwithstanding, but subject to the other terms, conditions and provisions 
contained in said Articles:

          (a)  Any corporate Tenant shall have the right, without the consent of
     Landlord, to assign this Lease or sublet all or any part of the Demised
     Premises to any corporation controlling, controlled by or under common
     control with Tenant, provided that no such assignee shall further assign
                          --------
     this Lease and no such sublessee shall assign or encumber its sublease or
     further sublet all or any part of the Demised Premises, and provided,
                                                                 --------
     further, that any event resulting in such assignee or sublessee ceasing to
     -------
     be a corporation controlling, controlled by or under common control with
     Tenant shall be deemed to be an assignment or sublease requiring the prior
     consent of Landlord and Tenant shall thereupon be required to comply with
     all provisions of Article 11 and this Article 48 applicable thereto. For
     purposes of the immediately foregoing, "control", means ownership of at
     least fifty one percent (51%) of the issued and outstanding voting stock of
     such corporation.

          (b)  Any corporate Tenant shall also have the right, without the
     consent of Landlord, to assign this Lease to any corporation succeeding to
     Tenant by merger or consolidation in accordance with applicable statutory
     provisions for merger or consolidation of corporations or by purchase of
     all or substantially all of Tenant's assets, provided that immediately
     after such merger, consolidation or purchase, the shareholders' equity
     (capital stock, additional paid-in capital and retained earnings) of the
     successor corporation or the purchasing corporation, as the case may be,
     shall be at least equal to the shareholder's equity of Tenant immediately

                                      13

<PAGE>
 
     prior to such merger, consolidation or purchase and this shall be so 
     certified by the chief financial officer of the assignee.

     It is Landlord's intent to permit assignment of the Lease and subletting 
pursuant to this Section 48.14 exclusively as an accommodation to the bona fide 
and legitimate business needs of Tenant, and notwithstanding the provisions 
hereof, no assignment of this Lease or sublease of all or any part of the 
Demised Premises without Landlord's consent hereunder shall be permitted where 
the sole or primary purpose of such assignment or subletting is to permit 
occupancy of all or any part of the Demised Premises by a third party in 
avoidance of Landlord's consent, or in the case of a corporation's purchasing 
all or substantially all of Tenant's assets where this Lease constitutes all or 
a substantial portion of such assets.

     Tenant shall promptly give Landlord prior written notice of any assignment 
of this Lease or subletting permitted under this Section 48.14 accompanied by 
all documentation required by Landlord to establish compliance with the 
requirements of subsections (a) and (b) above and Tenant shall also promptly 
provide Landlord with a copy of any executed instrument of merger, consolidation
or assignment or the executed sublease, as the case may be.

          49.   TENANT'S COOPORATION; REASONABLE
                MODIFICATIONS; ESTOPPEL CERTIFICATE
                -----------------------------------
          
          49.1  If, in connection with obtaining financing for the Building 
and/or the Real Estate, or otherwise upon the interest of the Landlord, as 
lessee, under any ground or underlying lease, any lending institution shall 
request reasonable modifications of this Lease as a condition of such financing,
Tenant covenants not unreasonably to withhold or delay its agreement to such 
modification, upon Landlord's request, provided that such modification does not 
materially or adversely affect the rights of Tenant under this Lease.

          49.2  Tenant agrees at any time and from time to time, upon not less 
than ten days' prior written request, that Tenant shall execute, acknowledge 
and deliver to Landlord, or its designee, a statement in writing certifying: 
that this Lease is unmodified and is in full force and effect (or if there have
been modifications, the specifics thereof and that the Lease is in full force
and effect as modified); the dates to which the Minimum Rent (or Adjusted
Minimum Rent) and additional rent have been paid; the amount of all rents paid
in advance, if any; and any other information that Landlord shall reasonably
request. Tenant further agrees to furnish Landlord upon demand at any time such
information and assurances as Landlord may request that Tenant has not breached
the provisions of this Lease. It is intended hereby that any such statement
delivered pursuant to this Article may be relied upon by a prospective purchaser
of the Landlord's interest or a mortgagee of Landlord's interest, or any
assignee of any mortgage upon Landlord's interests in the Real Estate. The
foregoing obligation shall be deemed a substantial obligation of the tenancy,
the breach of which shall give Landlord those remedies herein provided for an
event of default. Tenant's failure to timely deliver such statement shall be
conclusive upon Tenant: (a) that this Lease is in full force and effect, without
modification except as may be represented by Landlord; (b) that there are no
uncured defaults in Landlord's performance and Tenant has no right of offset,
counterclaim, defenses or deduction against the Minimum Rent, Adjusted Minimum
Rent, additional rent or against Landlord; and (c) that no more than one month's
installment of Minimum Rent has been paid in advance.

          49.3  Tenant agrees at any time it is in monetary default hereunder 
that Tenant shall demonstrate to Landlord upon not less than ten (10) days prior
written request Tenant's financial status and that of any occupant of the
Demised Premises by submitting to Landlord all reasonable information as
Landlord may request, including but not limited to a balance sheet as of a date
within ninety (90) days of Landlord's request therefor and statements of

                                      14


<PAGE>
 
income or profit and loss. The foregoing obligation shall be deemed a 
substantial obligation of the tenancy, the breach of which shall give Landlord 
those remedies herein provided for an event of default.

          50.   LIMITATION OF LIABILITY;
                DEFINITION OF "LANDLORD"
                ------------------------

          50.1  Notwithstanding anything to the contrary herein provided, each 
and every term, covenant, condition and provision of this Lease, is hereby made 
specifically subject to the provisions of this Article 50. The term "Owner" or 
"Landlord" as used in this Lease means only the owners or lessors for the time 
being of the Real Estate, so that in the event of any conveyance of such 
interest and the transfer to the transferee of any funds then being held under
this Lease by such owner, Landlord shall be and hereby is entirely freed and
relieved of any and all obligations of Landlord hereunder thereafter accruing,
and it shall be deemed without further agreement between the parties and such
grantee(s) that the grantee has assumed and agreed to observe and perform all
obligations of Landlord hereunder. It is specifically understood and agreed that
notwithstanding anything to the contrary herein provided or otherwise provided
at law or in equity, there shall be absolutely no personal liability in excess
of its interest in the Real Estate to the Landlord or any successor in interest
thereto (whether the same be an individual, joint venture, tenancy in common,
firm or partnership, general, limited or otherwise) or on the part of the
members of any firm, partnership or joint venture or other unincorporated
Landlord with respect to any of the terms, covenants and/or conditions of this
Lease; in the event of a breach or default by Landlord, or any successor in
interest thereof, of any of its obligations under this Lease, Tenant shall look
solely to the then Landlord for the satisfaction of each and every remedy of
Tenant, such exculpation of personal and additional liability which is in excess
of such interest in the Real Estate to be absolute and without any exception
whatsoever.

          51.   STATUTORY WAIVER; NOTICE BY TENANT
                ----------------------------------

          51.1  Tenant waives the benefit of N.J.S.A. 46:8-6 and 46:8-7, as same
may be amended. Tenant further waives its right under N.J.S.A 2A:18-60, as same 
be amended. Tenant agrees that it will not be relieved of the obligations to pay
the Minimum Rent, Adjusted Minimum Rent or any additional rent in case of damage
to or destruction of the Building, except as provided in Article 9 of the 
Printed Portion of this Lease.

          51.2  Tenant shall give Landlord prompt notice in case of fire or 
accident within the Demised Premises, or, upon the Real Estate if involving 
Tenant, its servants, agents, guests, employees, invitees or licensees.

          52.   CORPORATE AUTHORITY
                -------------------

          52.1  Tenant represents that the officer executing and delivering this
Lease has been duly authorized to enter into this Lease and that the execution 
and delivery of this Lease by Tenant do not and shall not violate any provision 
of any by-law, agreement, order, judgment, governmental regulation or any other 
obligation to which Tenant is a party or is subject.

          52.2  Upon Landord's request, Tenant shall deliver an appropriate 
certification by its secretary or assistant secretary to the above effect.

          52.3  Landlord represents that the officer executing and delivering 
this Lease has been duly authorized to enter into this Lease and that the 
execution and delivery of this Lease by Landlord do not and shall not violate 
any provision of any by-law, agreement, order, judgment, governmental regulation
or any other obligation to which Landlord is a party or is subject.

                                      15
<PAGE>
 
          53.   PERSONAL TAXES
                --------------

          53.1  Tenant agrees to pay all taxes imposed upon Tenant or on the 
personal property of Tenant in connection with its use and occupancy of the 
Demised Premises including, but not limited to, personal property, income, 
withholding and unemployment compensation, and to hold Landlord harmless from 
collection thereof out of monies due and owing Landlord.

          54.   BUILDING CHANGES
                ----------------

          54.1  This Lease shall not be affected or impaired by any change to
any lawns, sidewalk, driveways, parking areas or streets adjacent to or around
the Building, except as provided in the provisions of this Lease dealing with
condemnation.

          55.   HOLDING OVER
                ------------

          55.1  Tenant shall pay Landlord one and one-half (1 1/2) times the
fair market rental value of the Demised Premises, as determined by Landlord (but
in no event less than one and one-half (1 1/2) times the total of Adjusted
Minimum Rent plus additional rent then applicable under the Lease) for each
month or partial month during which Tenant retains possession of the Demised
Premises, or any part thereof, after the expiration or termination of the Lease.
Tenant understands that on the last day of the term of this Lease, all or a part
of the Demised Premises may be subject to certain rights of occupancy held by
other parties and that any retention of possession by Tenant after the last day
of the term of this Lease may cause significant hardship on Landlord and on
parties to whom certain rights of occupancy for all or any part of the Demised
Premises have been granted. In connection with the foregoing, Tenant shall
defend, indemnify and hold Landlord harmless against all liabilities and damages
sustained by reason of any such retention of possession. Nothing contained in
this Lease shall be construed as a consent by Landlord to the occupancy or
possession by Tenant of the Demised Premises beyond the Termination Date or
prior expiration of the term hereof, and Landlord, upon the Termination Date or
prior expiration of the term hereof, shall also be entitled to consequential
damages and to the benefit of all legal remedies that now may be in force or may
be hereafter enacted for summary possession of the Demised Premises.

          56.   RESTRICTIVE COVENANT - FOOD SERVICE
                -----------------------------------

          56.1  Tenant hereby covenants and agrees (anything to the contrary 
contained in this Lease, notwithstanding) that it shall not use the Demised 
Premises or any portion thereof, for the service of food to anyone other than 
Tenant's employees or guests, nor shall it maintain any facilities for the sale 
or consumption of food to and by anyone other than Tenant's employees or guests 
without, in each case, obtaining the prior written consent of the Landlord. The 
consent of the Landlord required hereunder may be withheld for any reason or no 
reason.

          56.2  Landlord represents to Tenant, and Tenant acknowledges, that 
pursuant to agreements made or to be made by and between the Landlord and third 
parties for the operation of a restaurant, cafeteria, coffee-cart and similar 
food services for this Building and/or other buildings in the office park in 
which this Building is located, no tenant of this Building, including Tenant, 
shall prepare, contract for, serve or otherwise make available a food service 
facility in competition with such third parties. Any breach of this restriction 
by the Tenant shall be deemed a material event of default under the terms of 
this Lease, and Landlord may, in its discretion, exercise such remedies as it 
may deem appropriate to terminate this Lease, prevent a violation of this 
covenant, and recover any damages to which it may be exposed by virtue of a 
breach by the Tenant.

          56.3  Tenant shall not permit the consumption of food or drink in the 
common areas of the Building.

          57.   NOTICES
                -------

          57.1  All notices, demands and requests which may or are required to 
be given by either party hereunder to the other, shall be in writing.  All

          58.   INTERPRETATION
                --------------

          58.1  If any term or provisions of this Lease or the application 
thereof to any party or circumstance shall to any extent be invalid or
unenforceable, the remainder of this Lease or the application of such term or
provision to parties or circumstances other than to those with respect to which
it is held invalid or unenforceable, shall not be affected thereby, and each
term and provision of this Lease shall be valid and enforced to the fullest
extent permitted by law.

          58.2  Time is of the essence with respect to the Tenant's obligation
to pay Minimum Rent, Adjusted Minimum Rent and additional rent hereunder.

          58.3  In any and all cases where Landlord's consent or approval is 
required under this Lease, Tenant shall upon Landlord's demand reimburse 
Landlord, as additional rent, for all reasonable costs and expenses, including 
but now limited to architectural, engineering and legal fees, which Landlord 
incurs in determining whether to grant its consent or approval.

          58.4  Tenant shall pay all reasonable legal fees and expenses incurred
by Landlord (i) in interpreting, enforcing or modifying the terms of the Lease, 
(ii) in commencing and prosecuting a suit for the recovery of the Demised 
Premises, damages or any amounts owed to Landlord, (iii) in commencing and 
prosecuting a declaratory action, (iv) in defending an action or counterclaim 
brought by Tenant and (v) in preparing for or appearing in an arbitration, 
mediation or other nonjudicial proceeding.

<PAGE>
 
          58.5  This Lease shall be governed by and construed in accordance with
the laws of and enforced only in the courts of New Jersey.  Tenant hereby 
irrevocably submits itself to the jurisdiction of the courts of the State of New
Jersey and to the jurisdiction of the United States District Court for the 
District of New Jersey for the purposes of any suit, action or other proceeding 
brought by Landlord arising out of or based upon this Lease.  Tenant hereby 
waives and agrees not to assert, by way of motion, as a defense, or otherwise, 
in any such suit, action or proceeding, any claim that it is not subject 
personally to the jurisdiction of the above-named courts, that its property is 
exempt or immune from attachment or execution, that the suit, action or 
proceeding is brought in an inconvenient forum, that the venue of the suit, 
action or proceeding is improper or that this Lease may not be enforced in or by
such court.

          58.6  This Lease shall be construed without regard to any presumption 
or other rule requiring construction against the party causing this Lease to be 
drafted.  Text deleted from a prior draft of this Lease shall not be admissible 
in an action or proceeding relating to the Lease for the purpose of altering or 
limiting the meaning or effect of the Lease.

          58.7  Tenant and Landlord each acknowledges and agrees that it has had
the assistance of counsel in the review, negotiation and execution of this Lease
or has waived its right to counsel.

          59.   NO OFFER OR AGREEMENT
                ---------------------

          59.1  No broker or agent of any broker has authority to make or agree 
to make a lease or any other agreement or undertaking in connection herewith, 
including, but not limited to the modification, amendment of or cancellation of 
a lease. The mailing or delivery of this document or any draft hereof by the 
Landlord or its agent to Tenant, its agent or attorney shall not be deemed an 
offer by the Landlord to lease the Demised Premises on the terms herein. This
Lease shall not be effective, nor shall Tenant have any rights with respect
thereto unless and until Landlord shall accept this Lease and execute and
deliver the same to Tenant.

          60.   DAMAGES
                -------

          60.1  Notwithstanding anything to the contrary contained in Article 18
hereof, if Landlord shall re-enter the Demised Premises under the provisions of 
Article 18, or in the event of the termination of this Lease, or of re-entry, by
or under any summary dispossess or other proceeding or action of any provision 
of law by reason of default hereunder on the part of Tenant, Tenant shall pay to
Landlord as damages, (i) a sum which at the time of such termination of this 
Lease or at the time of any such re-entry by Landlord, as the case may be, 
equals the aggregate Adjusted Minimum Rent payable hereunder which would have 
been payable by Tenant (conclusively presuming that additional rent on account 
of increases in Taxes and Building Operating Costs shall increase at the average
of the rates of increase thereof previously experienced by Landlord during the 
period not to exceed 3 years prior to such termination) for the period 
commencing with such earlier termination of this Lease or the date of such 
re-entry, as the case may be, and ending with the Termination Date, had this 
Lease not so terminated or had Landlord not so re-entered the Demised Premises 
plus (ii) the expenses or re-letting, including altering and preparing the 
Demised Premises for new tenants, brokers' commissions, attorney's fees and all 
other expenses properly chargeable against the Demised Premises and the rental 
thereof less any sums actually received by Landlord on account of such 
re-letting. Any such re-letting may be for a period shorter or longer than the 
remaining term of this Lease; but in no event shall Tenant be entitled to 
receive any excess of such net rents over the sums payable by Tenant to Landlord
hereunder, or shall Tenant be entitled in any suit for the collection of damages
pursuant to this subsection of a credit in respect of any net rents from a
reletting. If the Demised Premises or any part thereof should be re-let in
combination with the other space, then proper

                                      18
<PAGE>
 
apportionment on a square foot basis shall be made of the rent received from 
such re-letting and of the expenses of re-letting.

          60.2  Suit or suits for the recovery of such damages, or any 
installments thereof, may be brought by Landlord from time to time at its 
election, and nothing contained herein shall be deemed to require Landlord to 
postpone suit until the date when the term of this Lease would have expired if 
it had not been so terminated or had Landlord not re-entered the Demised 
Premises. Nothing herein contained shall be construed to limit or preclude 
recovery by Landlord against Tenant of any sums or damages to which, in addition
to the damages particularly provided above, Landlord may lawfully be entitled by
reason of any default hereunder on the part of Tenant. Any indemnity of Tenant 
shall survive the expiration or earlier termination of this Lease. Nothing 
herein contained shall be construed to limit or prejudice the right of Landlord 
to prove for and obtain as liquidated damages by reason of the termination of 
this Lease or re-entry of the Demised Premises for the default of Tenant under 
this Lease, an amount equal to the maximum allowed by any statute or rule of law
governing the proceedings in which such damages are to be proved whether or not 
such amount be greater, equal to, or less than any of the sums referred to in 
Section 60.1.

          61.   BANKRUPTCY
                ----------

          61.1  If, as a matter of law, Landlord has no right on the bankruptcy 
of Tenant to terminate this Lease, then, if Tenant, as debtor, or its trustee 
wishes to assume or assign this Lease, in addition to curing or adequately 
assuring the cure of all defaults existing under this Lease on Tenant's part on 
the date of filing of the proceeding (such assurances being defined below), 
Tenant, as debtor, or the trustee or assignee, must also furnish adequate 
assurances of future performance under this Lease (as defined below). Adequate 
assurance of curing defaults means the posting with Landlord of a sum in cash 
sufficient to defray the cost of such a cure. Adequate assurance of future 
performance under this Lease means posting a deposit equal to three (3) months' 
rent, including all other charges payable by Tenant hereunder, such as the 
amounts payable pursuant to Article 36 hereof, and, in the case of an assignee,
assuring Landlord that the assignee is financially capable of assuming this
Lease, and that its use of the Demised Premises will not be detrimental to the
other tenants in the Building or Landlord. In a reorganization under Chapter 11
of the Bankruptcy Code, the debtor or trustee must assume this Lease or assign
it within one hundred twenty (120) days from the filing of the proceeding, or he
shall be deemed to have rejected and terminated this Lease.

          61.2  If this Lease is assigned to any person or entity pursuant to 
the provisions of the Bankruptcy Code, 11 U.S.C. Section 101 et seq. (the 
"Bankruptcy Code"), any and all monies or other considerations to be delivered 
in connection with the assignment shall be delivered to Landlord, shall be and 
remain the exclusive property of Landlord and shall not constitute property of 
Tenant or of the estate of Tenant within the meaning of the Bankruptcy Code. Any
person or entity to which this Lease is assigned pursuant to the provisions of 
the Bankruptcy Code shall be deemed to have assumed all of the obligations 
arising under this Lease on and after the date of the assignment, and shall upon
demand execute and deliver to Landlord an instrument confirming that assumption.

          62.   SECURITY
                --------

          62.1  In the event Landlord applies or retains any portion or all of 
the security deposited, Tenant shall forthwith restore the amount so applied or 
retained so that at all times the amount deposited with Landlord shall be not 
less than $17,504.38.

          62.2  Landlord shall deposit any cash security received from Tenant on
the date hereof in an interest bearing account in a commercial banking 
institution, subject to Landlord's right to

                                      19
          
<PAGE>
 
apply the security as provided in Article 34 and subject to Tenant's obligation 
to restore the amount of security should Landlord apply or utilize all or any 
portion thereof. The interest bearing account in which the security is to be 
deposited shall be in a commercial banking institution selected by Landlord and 
may from time to time be transferred by Landlord to another commercial banking 
institution of Landlord's choice. Any interest earned on the security shall be 
earned for the account of Tenant and shall be held by Landlord as additional 
security thereunder; except that Landlord may retain one percent (1%) of the 
security annually as an administrative fee.

          63.   PARTNERSHIP TENANT
                ------------------

          63.1  If Tenant is a partnership, joint venture or unincorporated
association (or is comprised of two (2) or more persons, individually and as co-
partners of a partnership) or if Tenant's interest in this Lease shall be
assigned to a partnership, joint venture or unincorporated association (or to
two (2) or more persons, individually and as co-partners of a partnership)
pursuant to Articles 11 and 48 (any such partnership and such persons are
referred to in this Section as "Partnership Tenant"), the following provisions
of this Section shall apply to such Partnership Tenant; (i) the liability of
each of the persons comprising Partnership Tenant shall be joint and several,
individually and as a partner, and (ii) each of the persons comprising
Partnership Tenant, whether or not such person shall be one of the persons
comprising Tenant at the time in question, hereby consents in advance to, and
agrees to be bound by, any written instrument which may hereafter be executed,
changing, modifying or discharging this Lease, in whole or in part, or
surrendering all or any part of the Demised Premises to Landlord, and by any
notices, demands, requests or other communications which may hereafter be given,
by Partnership Tenant or by any of the persons comprising Partnership Tenant,
and (iii) any bills, statements, notices, demands, requests or other
communications given or rendered to Partnership Tenant or to any of the persons
comprising Partnership Tenant shall be deemed given or rendered to Partnership
Tenant and to all such persons and shall be binding upon Partnership Tenant and
all such persons, and (iv) if Partnership Tenant shall admit new partners, all
of such new partners shall, by their admission to partnership Tenant, be deemed
to have assumed performance of all of the terms, covenants and conditions of
this Lease on Tenant's part to be observed and performed, and shall be liable
for such performance, together with all other partners, jointly or severally,
individually and as a partner, and (v) if any partners shall leave Partnership
Tenant, all of such departing partners shall nevertheless remain liable for
performance of all the terms, covenants, and conditions of this Lease on
Tenant's part to be observed and performed and shall continue to be liable for
such performance, together with all currently admitted partners, jointly or
severally, individually and as a partner, and (vi) Partnership Tenant shall give
prompt notice to Landlord of the admission of any such new partners, and upon
demand of Landlord, shall cause each such new partner to execute and deliver to
Landlord an agreement in form satisfactory to Landlord, wherein each such new
partner shall so assume performance of all of the terms, covenants and
conditions of this Lease on Tenant's part to be observed and performed (but
neither Landlord's failure to request any such agreement nor the failure of any
such new partner to execute or deliver any such agreement to Landlord shall
vitiate the provisions of subdivision (iv) of this Section).

          64.   LANDLORD'S WORK; LANDLORD'S WORK LETTER
                ---------------------------------------

          64.1  Annexed hereto as Exhibit "B" and made a part hereof is Proposal
10196; SK-1 dated 10/12/93; SK-2 dated 10/12/93; SK-3 dated 10/12/93; TA-3c 
dated 10/12/93; TA-3d dated 1/12/93 (collectively referred to as the "Work 
Letter"). Tenant agrees that it shall provide to Landlord on or before November 
1, 1993, such final drawings and specifications (which must first be approved in
writing by Landlord) for Tenant's layout, partitioning, electrical, reflecting 
ceiling and other installations. Landlord shall furnish and install in 
accordance with such final and approved drawings and specifications, so much of 
the work described

                                      20
<PAGE>
 
in said final and approved drawings and specifications and in the Work Letter as
allowed by a construction credit of $304,876.86 ("Construction Credit"). To the 
extent Tenant's final and approved drawings and specifications require work, the
cost of which exceeds the Construction Credit, such work shall be reduced to an 
"Extra" or "Change Order" to be executed by both Landlord and Tenant, which
shall indicate the work required, the cost thereof to be paid by Tenant upon
demand, and the additional time required, if any, for completion. Any or all of
the Construction Credit that remains unexpended as of the Commencement Date
shall be deemed null and void and forever forfeited. Tenant shall be responsible
for any delays in completing the Demised Premises by reason of Tenant's failure
to cooperate with Landlord, Tenant's delays in submitting any drawings or
specifications, or in supplying information, or in approving drawings,
specifications or estimates, or in giving authorizations, or by reason of any
"Extra" or "Change Order" designated by Tenant, or by reason of any changes by
Tenant in any designations previously made by Tenant, or by reason of any
similar acts or omissions of Tenant or by reason of any cause or factor beyond
Landlord's reasonable control, including but not limited to strikes or other
labour disputes, accidents, orders or regulations of any federal, state, country
or municipal authority, delays due to adjustment or insurance claims, lack of
availability of materials, parts or services, acts of God, fire, earthquake,
floods, explosion, action of the elements, war, hostilities, invasion,
insurrection, riot, mob violence, sabotage or by reason of any other cause,
whether similar or not to the foregoing, that is beyond the reasonable control
of Landlord. If the commencement Date does not occur on or before the Estimated
Commencement Date by virtue of any of the reasons set forth in the immediately
preceding sentence, then the Commencement Date shall be deemed, notwithstanding
anything contained to the contrary in Article 37, to have occurred on the
Estimated Commencement Date.

          65.   RENEWAL OPTION
                --------------

          65.1  Subject to the provisions of Section 65.2 below, Tenant shall 
have the option to renew this Lease for an additional term of five (5) years 
(the "Renewal Term"), which Renewal Term shall commence upon the expiration  of 
the term described in Article 37 of this Lease (the "Initial Term"). The terms, 
covenants and conditions during the Initial Term, including but not limited to 
the definitions of the First Tax Year and First Operating Year as set forth in 
Article 36 hereof, shall be projected and carried over into the Renewal Term, 
except as specifically set forth hereinafter. 

          (a)   The Minimum Rent during the Renewal Term shall be the greater of
(i) Market Rent (as defined in clause (b) below) or (ii) the Adjusted Minimum 
Rent as of the last day of the Initial Term.

          (b)   "Market Rent" shall mean the fair market rent for the Demised 
Premises, as of the commencement date of the Renewal Term (the "Determination 
Date"), based upon the rents generally in effect for comparable office space in 
the area in which the Real Estate is located. Market Rent (for the purposes of 
determining the Minimum Rent only during the Renewal Term) shall be determined 
on what is commonly known as "gross" basis; that is, in computing Market Rent, 
it shall be assumed that all real estate taxes and expenses for customary 
services are included in such Market Rent and are not passed through to the 
Tenant as separate additional charges. Notwithstanding the foregoing, the 
Minimum Rent for the Renewal Term shall be thereafter increased form time to
time as provided in this Lease and the First Tax Year and First Operating Year
for the Renewal Term shall be defined as provided in Article 36 hereof.

          (c)   Landlord shall notify Tenant ("Landlord's Determination Notice")
of Landlord's determination of the Market Rent within sixty (60) days of the
Determination Date. If Tenant disagrees with Landlord's determination, Tenant
shall notify Landlord ("Tenant's Notice of Disagreement") within fifteen (15)
days of receipt of Landlord's Determination Notice. Time shall be

                                      21













<PAGE>
 
of the essence with respect to Tenant's Notice of Disagreement, and the failure 
of Tenant to give such notice within the time period set forth above shall 
conclusively be deemed an acceptance by Tenant of the Market Rent as determined 
by Landlord and a waiver by Tenant of any right to dispute such Market Rent. If 
Tenant timely gives its Tenant's Notice of Disagreement, then the Market Rent 
shall be determined as follows: Landlord and Tenant shall, within thirty (30) 
days of the date on which Tenant's Notice of Disagreement was given, each 
appoint an Appraiser (hereinafter defined) for the purpose of determining the 
Market Rent. An Appraiser shall mean a duly qualified impartial real estate 
appraiser having at least ten (10) years' experience in the area in which the 
Demised Premises are located. In the event that the two (2) Appraisers so 
appointed fail to agree as to the Market Rent within a period of thirty (30) 
days after the appointment of the second Appraiser, such two (2) Appraisers 
shall forthwith appoint a third Appraiser who shall make a determination within 
thirty (30) days thereafter. If such two Appraisers fail to agree upon such 
third Appraiser within ten (10) days following the last thirty (30) day period, 
such third Appraiser shall be appointed by a presiding Judge of the Superior 
Court of the State of New Jersey for the County in which the Real Estate is 
located. Such two (2) Appraisers or three (3) Appraisers, as the case may be, 
shall proceed with all reasonable dispatch to determine the Market Rent. The 
decision of such Appraisers shall be final; such decision shall be in writing 
and a copy shall be delivered simultaneously to Landlord and to Tenant. If such 
Appraisers fail to deliver their decision as set forth above prior to the 
commencement of the Renewal Term, Tenant shall pay Landlord the Adjusted Minimum
Rent at the rate as of the last day of the Initial Term, until such decision is 
so delivered. If the Market Rent as determined above is in excess of the actual 
rent paid, then Tenant, upon demand, shall pay to Landlord the difference 
between the actual rent paid and the Market Rent from the commencement of the 
Renewal Term. Landlord and Tenant shall each be responsible for and shall pay 
the fee of the Appraiser appointed by them respectively, and Landlord and Tenant
shall share equally the fee of the third Appraiser. Promptly upon determination
of the Market Rent, Tenant shall execute and deliver a Lease amendment prepared
by Landlord setting forth the terms of the Renewal Term.

          65.2  Tenant's option to renew, as provided in Section 65.1 above,
shall be strictly conditioned upon and subject to each of the following:

          (a)   Tenant shall notify Landlord in writing of Tenant's exercise of
its option to renew at least six (6) months, but not more than twelve (12)
months, prior to the expiration of the Initial Term;

          (b)   At the time Landlord receives Tenant's notice as provided in (a)
above, and at the expiration of the Initial Term, Tenant shall not have been in
default under the terms or provisions of this Lease and the Tenant named on the
first and last page of this Lease shall be in occupancy of the entire Demised
Premises;

          (c)   Tenant shall have no further renewal option other than the
option to extend for the one Renewal Term as set forth in Section 65.1 above;

          (d)   This option to renew shall be deemed personal to the Tenant
named on the first and last page of this Lease and may not be assigned;

          (e)   Landlord shall have no obligation to do any work or perform any
services for the Renewal Term with respect to the Demised Premises or the
Building which Tenant agrees to accept in their then "as is" condition; and

          (f)   No later than ten (10) days prior to the commencement of the
Renewal Term, Tenant shall deposit with Landlord such additional sums as may be
required to increase any security deposit then held by Landlord proportionate to
the increase in the Minimum Rent.

                                      22


<PAGE>
 
          66.   ISRA COMPLIANCE
                ---------------

          66.1  Tenant shall, at Tenant's own expense, comply with the 
Industrial Site Recovery Act, (N.J.S.A. 13:1K-6 et seq.), the Comprehensive
Environmental Response, Compensation & Liability Act (42 U.S.C. 9601 et seq.)
and the Spill Compensation and Control Act (N.J.S.A. 58:10-23.11 et seq.) and
any and all environmental laws, amendments thereto and the regulations and
orders promulgated thereunder with respect to Tenant's use and occupancy of the
Demised Premises. Tenant shall, at Tenant's own expense, make all submissions
to, provide all information to, and comply with all requirements of, the Bureau
of Industrial Site Evaluation ("the Bureau") of the New Jersey Department of
Environmental Protection and Energy ("NJDEPE"). Should the Bureau or any other
division of NJDEPE determine that a cleanup plan be prepared and that a cleanup
be undertaken because of any spills or discharges of hazardous substances or
wastes in or about the Real Estate caused by Tenant which occur during the term
of this Lease, then Tenant shall, at Tenant's own expense, prepare and submit
the required plans and financial assurances, and carry out the approved plans.
Tenant's obligations under this Article shall arise if there is any closing,
terminating or transferring of operations of an industrial establishment
utilizing the Demised Premises or a transfer of the Real Estate or any portion
thereof which falls under the purview of the statutes hereinbefore referred.

          66.2  At no expense to Landlord, Tenant shall promptly provide all 
information requested by Landlord for preparation of non-applicability 
affidavits and shall promptly sign such affidavits when requested by Landlord. 
Tenant shall indemnify, defend and save harmless Landlord from all fines, suits,
procedures, claims and actions of any kind arising out of or in any way 
connected with any spills or discharges of hazardous substances or wastes in or 
about the Real Estate caused by Tenant which occur during the term of this 
Lease; and from all fines, suits, procedures, claims and actions of any kind 
arising out of Tenant's failure to provide all information, make all submissions
and take all actions required by the Bureau or any other division of NJDEPE. 
Tenant's obligations and liabilities under this Article shall continue so long 
as Landlord remains responsible for any spills or discharges of hazardous 
substances or wastes in or about the Real Estate caused by Tenant which occur 
during the term of this Lease. Tenant's failure to abide by the terms of this 
Article shall be restrainable by injunction.

          67.   PREPAID RENT
                ------------

          67.1  Tenant shall pay Landlord prepaid rent equal to the sum of five 
(5) monthly installments of Minimum Rent, two (2) monthly installments of which
shall be due on the date hereof and three (3) monthly installments of which
shall be due on or before the Commencement Date. Said prepaid rent shall be
deposited in the same interest bearing account (described in Section 62.3
hereof) in which the security is deposited. All the prepaid rent [plus any
interest earned thereon less the one percent (1%) annual administrative fee
referred to in Section 62.3 hereof] actually received by Landlord on or before
the Commencement Date shall be applied by Landlord against (i) the monthly
installment of Minimum Rent due for the tenth (10th) Lease month of the term and
(ii) the consecutive monthly installments of Minimum Rent due for each Lease
month of the term thereafter until the prepaid rent [plus any interest earned
thereon less the one percent (1%) annual administrative fee referred to in
Section 62.3 hereof] is entirely expended.

          68.   RIGHT OF FIRST/SECOND OFFER
                ---------------------------

          68.1  The following units of space currently exist on the second 
(2nd) and third (3rd) floors of the Building: 1,926 rentable square feet of 
vacant space on the third floor, 20,843 rentable square feet of leased spaced on
the third floor, 8,132 rentable square feet of vacant space on the second floor
(the "PC Strategies Space"), 2,558 rentable square feet of leased space on the
second floor and 9,900 rentable square feet of leased space on the second

                                      23
<PAGE>
 
floor. All of the above-referenced premises are hereinafter collectively 
referred to as the "Option Space". Landlord agrees that if all or any portion of
the Option Space shall become available during the term of this Lease, then in 
any such case, before offering the available Option Space (other than the PC 
Strategies Space) to any other party, Landlord will first offer to Tenant the 
right to include the Option Space (other than the PC Strategies Space) within 
the Demised Premises on the Inclusion Date (hereinafter defined) upon all of the
terms and conditions of this Lease, as if the Option Space had been part of the 
Demised Premises on the Commencement Date, except as specifically set forth 
hereinafter. With respect to the PC Strategies Space, Landlord agrees that if 
the PC Strategies Space shall become available during the term of this Lease, 
then, subject to the rights of PC Strategies & Solutions, Inc., Landlord will 
offer to Tenant the right to include the PC Strategies Space within the Demised 
Premises on the Inclusion Date upon all of the terms and conditions of this 
Lease, as if the PC Strategies Space had been part of the Demised Premises on 
the Commencement Date, except as specifically set forth hereinafter. The 
Inclusion Date shall be the date on which Tenant exercises its option pursuant 
to the terms of this Article.

     (a)  In the event Tenant exercises its option pursuant to the terms of this
Article within twelve (12) months from the Commencement Date (the "Anniversary 
Date") the Minimum Rent payable with respect to the Option Space shall be $17.50
per rentable square foot and Tenant shall be entitled to a construction 
allowance of $23.00 per rentable square foot (based on a five year term and 
reduced on a pro-rata basis for any term less than five years) for work 
performed by Landlord's affiliate, Bellemead Construction Corporation within the
Option Space. In the event Tenant exercises its option pursuant to the terms of 
this Article at any time after the Anniversary Date, the Minimum Rent payable 
with respect to the Option Space shall commence on the Inclusion Date and shall 
be (i) the Market Rent (as defined in clause (b) below) which shall in no event 
be less than (ii) the product of (1) the adjusted Minimum Rent per square foot 
with respect to the Demised Premises on the date Landlord's offer is made and
(2) the rentable square foot area of the Option Space.

     (b)  "Market Rent" shall mean the fair market rent for the Option Space as 
of the Inclusion Date based upon the rents generally in effect for comparable 
office space in the area in which the Building is located. Market Rent (for the 
purposes of determining the Minimum Rent for the Option Space only) shall be 
determined on what is commonly known as "gross" basis; that is, in computing 
Market Rent it shall be assumed that all real estate taxes and customary 
services are included in such additional charges. Notwithstanding the foregoing,
the Minimum Rent for the option Space shall be thereafter increased from time to
time as provided in this Lease.

     (c)  Landlord shall notify Tenant ("Landlord's Determination Notice") of 
Landlord's determination of the Market Rent on or before the Inclusion Date. If 
Tenant disagrees with Landlord's determination, Tenant shall notify Landlord 
("Tenant's Notice of Disagreement") within fifteen (15) days after receipt of 
Landlord's Determination Notice. Time shall be of the essence with respect to 
Tenant's Notice of Disagreement, and the failure of Tenant to give such notice 
within the time period set forth above shall conclusively be deemed an 
acceptance by Tenant of the Market Rent as determined by Landlord and a waiver 
by Tenant of any right to dispute such Market Rent. If Tenant timely gives its 
Tenant's Notice of Disagreement, then the Market Rent shall be determined as 
follows: Landlord and Tenant shall, within thirty (30) days after the date on 
which Tenant's Notice of Disagreement was given, each appoint an Appraiser 
(hereinafter defined) for the purpose of determining the Market Rent. An 
Appraiser shall mean a duly qualified impartial real estate appraiser having at
least ten (10) years experience in the area in which the Building is located. In
the event that the two (2) Appraisers so appointed fail to agree as to the
Market Rent within a period of thirty (30) days after the appointment of the
second Appraiser, such two (2) Appraisers shall

                                      24
<PAGE>
 
forthwith appoint a third Appraiser who shall make a determination within 
thirty (30) days thereafter.  If such two (2) Appraisers so appointed fail to 
agree upon such third Appraiser within ten (10) days following the last thirty 
(30) day period, such third Appraiser shall be appointed by a presiding Judge of
the Superior Court of the State of New Jersey for the County in which the 
Building is located.  Such two (2) Appraisers or three (3) Appraisers, as the 
case may be, shall proceed with all reasonable dispatch to determine the Market 
Rent.  The decision of such Appraisers shall be final; such decision shall be in
writing and a copy shall be delivered simultaneously to Landlord and to Tenant. 
Tenant shall pay Landlord Adjusted Minimum Rent on the Option Space at the rate 
set forth in Section 68.1(a) (ii) hereof until such decision is so delivered.  
If the Market Rent as determined above is in excess of actual rent paid, then
Tenant, upon demand, shall pay to Landlord the difference between the actual
rent paid and the Market Rent from the Inclusion Date. Landlord and Tenant shall
each be responsible for and shall pay the fee of the Appraiser appointed by them
respectively, and Landlord and Tenant shall share equally the fee of the third
Appraiser. Promptly upon determination of the Market Rent, Tenant shall execute
and deliver a Lease amendment in a form satisfactory to Landlord reflecting the
inclusion of the Option Space within the Demised Premises on the Inclusion Date.

     68.2  Landlord shall make the foregoing offer in writing, and Tenant shall 
have the right to exercise such option with respect to the Option Space if 
Tenant shall not have breached any term or provision of the Lease and the 
Tenant named on the first and last page of the Lease is in occupancy of the 
entire Demised Premises.  Tenant may only exercise such option by written notice
received by Landlord within ten (10) days after Landlord makes such offer to 
Tenant.  For an option exercised after the Anniversary Date, Tenant shall accept
the Option Space in its "as is" physical condition as of the Inclusion Date and 
agrees that Landlord will not be required to do any work or perform any services
therein. In addition to the foregoing, Tenant shall be prohibited from leasing
any of the Option Space for a term less than eighteen (18) months. If Tenant
does not accept the offer made by Landlord pursuant to the provisions of this
Article 68 with respect to the Option Space, Landlord shall be under no further
obligation to Tenant with respect to the Option Space or any part thereof and
Tenant shall have forever waived and relinquished its right to the Option Space
and any part thereof and Landlord shall at any and all times thereafter be
entitled to lease such space in whole or in part, or in whole or in parts in
conjunction with any other space, to others at such rental and upon such terms
and conditions as Landlord, in its sole discretion may desire whether such
rental terms, provisions and conditions are the same as those offered to Tenant
or more or less favorable. Tenant agrees not to acquire the Option Space
pursuant to this Article 68 for the primary purpose of subletting or otherwise
disposing of the same or any part thereof to others.

     68.3  If the Option Space shall not be available for Tenant's occupancy on 
the Inclusion Date for any reason including the holding over of the prior 
tenant, then Landlord and Tenant agree that the failure to have such Option 
Space available for occupancy by Tenant shall in no way affect the validity of 
this Lease or the inclusion of the Option Space within the Demised Premises as 
of the inclusion of the Option Space within the Demised Premises as of the
Inclusion Date or the obligations of Landlord and Tenant hereunder, nor shall
the same be construed in any way to extend the term of this Lease. Within ten
(10) days after Tenant's exercise of this option for the Option Space, Tenant
shall deposit with Landlord such additional sums as may be required by Landlord
to increase the security deposit, if any, then held by Landlord proportionate to
the increase in Minimum Rent. Tenant's rights under this Article shall be deemed
personal to the Tenant named on the first and last page of this Lease and may
not be assigned.

Tenant's actions, or delays caused by events wholly beyond the control of
Landlord, the Landlord Improvements described in clauses (a) and (f) (except
with respect to the portion of the roof above the office spaces in the Building)
of Section 4.01 shall be substantially completed on or before the January 15,
1997. The Landlord Improvements pertaining to the removal and replacement of the

delayed for reasons other than those described in this Section 4.03, and fails
to achieve substantial completion of the Landlord Improvements, or final
completion of the Landlord Improvements, within the times provided herein, then
the Tenant's sole and exclusive remedy for such failure shall be to recover from
the Landlord the sum of $150.00 for each such calendar day substantial
completion or final completion, as the case may be, is so delayed by Landlord
and provided that such delay continues for five (5) business days following
written notice by Tenant of such failure. The parties acknowledge and agree that
it would be extremely difficult and impracticable under the presently known and
anticipated circumstances to ascertain and fix the actual damages that the

however, that such obligation shall not include making any structural or system
repairs to the Building, except for the Tenant Work or structural or system
repairs to the Building required to correct damage caused by Tenant or Tenant's
invitees. Tenant shall not be deemed to have violated this covenant solely
because of non-compliance or alleged non-compliance with any regulation, order,
direction or rule issued by the U.S. Food and Drug Administration, or any state

                    ----------------
written notice to Landlord, to contest by appropriate legal proceedings, without
cost or expense to Landlord, the validity of any Laws so long as (a) such
contest is prosecuted in good faith, and (b) no sale or other action in
connection therewith is threatened against the Premises or Landlord. If at any
time, such a sale or other action against the Premises or Landlord is
threatened, then Tenant either (i) shall

<PAGE>
 
comply with the Laws, or (ii) post such bonds or other security with the court

amount to prevent such threat. Tenant agrees to indemnify and hold harmless
Landlord against any and all liability, loss, damage, cost and expense which
Landlord may sustain during the Term by reason of Tenant's contest, including
but not limited to any penalties which may be levied or assessed against the
Landlord or the Premises. In the event that any such contest by Tenant involves
the dispute over the payment of any fine, penalty, or other charge, and so long
as Tenant is not in default under this Lease, and in good faith and by
appropriate legal action shall contest the validity of any such fine, penalty or
charge, and shall have established by deposit of cash with Landlord, or other
securities satisfactory to Landlord, a reserve for the payment thereof in such
amount shall be subject to such contest , the Tenant shall not be required to
pay the contested item or produce the required receipt while the reserve is
maintained and so long as the contest that operates to prevent collection is
maintained and prosecuted with diligence, and shall not have been terminated or
discontinued adversely to Tenant. Any such cash held in reserve with Landlord
shall be deposited by Landlord with a federally insured financial institution in
a separate escrow or trust account, and such funds shall not be co-mingled with
other monies of the Landlord.

Premises with thirty (30) days of the date of this Lease.  In the event that
Landlord fails to obtain such title within such thirty (30) day period Tenant
may elect to terminate this Lease upon written notice to Landlord of such
election.  Notwithstanding whether Tenant elects to terminate, Landlord shall
indemnify, defend, and hold Tenant harmless from and against any liability,
loss, cost and expense incurred by Tenant as a result of Landlord failing to
acquire such title as aforesaid.

     Section 9.01.  Structural Alterations.  Except as provided in Section 9.02

hereof, and other than the Tenant Work, Tenant will make no other structural
alterations to the Premises or any part thereof , without the prior written
consent of Landlord, which consent will not be unreasonably withheld,
conditioned, or delayed. Landlord shall not withhold, its consent unless such
structural alterations would materially change the character, appearance or use
of the Premises, or would weaken or impair the structural integrity or lessen
the value of the Premises or any part thereof. Any such permitted alterations
shall be performed in accordance with plans and specifications, and a
construction schedule, previously approved in writing Landlord. Nevertheless,
Tenant shall be permitted to install roof top HVAC units in accordance with
plans and specifications previously approved in writing by Landlord. The
location of such roof top HVAC units shall be subject to Landlord's reasonable
discretion, and such installation shall be performed by a licensed mechanical
contractor, which contractor shall be subject to Landlord's approval, which
approval shall not be unreasonably withheld, conditioned or delayed. Any such
structural alterations to the Premises shall be subject to the same conditions
as apply to the Tenant Work pursuant to Section 4.02 hereof.

nonstructural alterations, additions, and improvements in and to the Premises as
it may deem desirable for its use, provided that Tenant notifies Landlord of
Tenant's intention to perform such alterations, additions and improvements and
provides Landlord with a copy of any plans and specifications relating thereto.
Any such non-structural alterations to the Premises shall be subject to the same
conditions as apply to the Tenant Work pursuant to Section 4.02 hereof.

     Section 9.03  Mechanics' Liens.  Tenant shall not, in the making of any
                   ----------------
repairs or alterations pursuant to the provision of this Lease, suffer or permit
any mechanic's, laborer's or materialmen's lien to be filed against the
Premises, Building, or any part thereof by reason of labor or materials supplied
or claimed to have been supplied to Tenant; and if any such lien shall be filed,
Tenant, within forty-five days after notice of filing, shall cause it to be
discharged of record. In the event that Tenant fails to discharge any such lien
as aforesaid, then Landlord may, but shall not be required to, cause such lien
to be discharged. Any such payments or expenses incurred by Landlord in
connection therewith, shall constitute Additional Rent hereunder and shall be
due and payable with the next monthly installment of Fixed Basic Rent. Tenant
shall

     Section 10.01.  Insurance.  Tenant, at Tenant's sole cost and expense,
                     ---------
shall keep or cause the Premises to be kept continuously insured during the
Term, under policies providing the following insurance coverages: (i) commercial
general liability insurance on an occurring basis with a combined single limit
for bodily injury and property damage of not less than $2,000,000.00, including
the broad form general liability endorsement, contract liability, and products
liability coverage; and (ii) a policy of standard fire, extended coverage and
special extended coverage insurance (all risks), including a vandalism and
malicious mischief endorsement, in an amount equal to the full replacement value
of the Premises, new and without deduction for depreciation of fixtures,
furniture and improvements. On or before the Rent Commencement Date, Tenant
shall provide Landlord with satisfactory evidence that such insurance is in full
force and effect or effectively renewed and that the insurance premiums for such
insurance have been paid for the first year of the term. Tenant's obligation to
carry or maintain any insurance required to be maintained by Tenant under the
Lease may be satisfied by Tenant by providing such coverages under Tenant's
existing blanket insurance policy. Such liability policy shall name Landlord as
an additional insured, and such casualty policy shall name Landlord as the loss
payee, and shall provide for at least thirty (30) days' prior notice of
cancellation or modification to Landlord. Upon the execution of this Lease,
Tenant shall deposit certificates evidencing such insurance coverages with
Landlord, and thereafter shall deposit with Landlord certificates evidencing
renewal of such coverages at least fifteen (15) days prior to the expiration
thereof. In the event that Tenant shall fail to maintain any such required
insurance coverages during the Term, Landlord may, but shall not be obligated
to, procure and obtain such insurance coverages and Landlord's costs for such
insurance shall constitute Additional Rent hereunder and shall be due and
payable with the next monthly installment of Fixed Basic Rent.

     Section 10.02.  Damage or Casualty.
                     ------------------

          (a) In case the Premises or any portion thereof shall be totally or
partially damaged or destroyed by fire or by any other casualty whatsoever, then
Landlord and Tenant shall proceed with reasonable promptness, and in accordance
with paragraph (c) below, to repair

                                      15
<PAGE>
 
and restore the Premises to at least as good a condition as that which existed
immediately prior to such fire or other casualty and during such repair period,
there shall be an abatement of rent. In the event Landlord receives any
insurance proceeds from the property insurance maintained by Tenant pursuant to
Section 10.01, Landlord shall turn such proceeds over to Tenant for the purpose
of making such repairs.

          (b) In the event that any of the insurance monies paid by the
insurance companies to Tenant shall remain after the completion of such repairs,
restoration or reconstruction, the excess shall be paid to or retained by
Tenant, as Tenant's property.  In the event that the proceeds of any insurance
policies are insufficient to restore the Premises to the condition that they
were in prior to the occurrence of the casualty, either party hereto may
terminate this Lease upon ten (10) days prior written notice to the other party
of such election, and the Lease shall terminate on the date set forth in such
notice unless the other party shall elect and agree to pay any short fall
necessary to effect the required repairs, restoration or reconstruction, and in
which case the insurance proceeds shall be apportioned between the parties
hereto in the same proportion as the cost of the Tenant Work bears to the
aggregate of the cost of the Landlord Improvements plus (i) the actual cost to
Landlord to acquire the Building (exclusive of the land and appurtenances) or
(ii) $1,800,000, whichever is less.

          (c) All repairs, restoration and reconstruction to the interior of the
Building, or other portions of the Premises comprising the Tenant Work shall be
performed by Tenant subject to the conditions set forth in Section 4.02 and
Section 9.01 hereof.  All repairs, restoration and reconstruction to the
exterior of the Building, or other exterior improvements to the Premises shall
be performed by Landlord.  The parties shall cooperate with one another and
shall have mutual responsibility for the adjustment of all insurance claims.

     Section 10.03.  Cooperation in Actions.  Landlord and Tenant each will
                     ----------------------
cooperate with the other, to such extent as such other party may reasonably
require, in connection with the prosecution or defense of any action or
proceeding arising out of, or for the collection of any insurance monies that
may be due in the event of, any loss or damage, and each will execute and
deliver to such other party such instruments as may be required to facilitate
the recovery of any insurance monies.

     Section 10.04.  Notice of Casualty.  Tenant shall give prompt written and
                     ------------------
verbal notice to Landlord with respect to all fires or other casualties
occurring upon the Premises.

     Section 10.05.  Waiver of Subrogation; Rights Under Insurance Policies.
                     ------------------------------------------------------
Each of the parties hereto hereby release the other, to the extent of the
releasing party's insurance coverage, from any and all liability for any loss or
damage which may be inflicted upon the Premises of such party even if such loss
or damage shall be brought about by the fault or negligence of the other party,
its agents or employees; provided, however, that this release shall be effective
only with respect to loss or damage occurring during such time as the
appropriate policy of insurance shall contain a clause to the effect that this
release shall not affect said policy or the right of the insured to recover
thereunder. If any policy does not permit such a waiver, and if the party to

                                      16

benefit therefrom requests that such a waiver be obtained, the other party
agrees to obtain an endorsement to its insurance policies permitting such waiver
of subrogation if it is available and if such policies do not provide therefor.
If an additional premium is charged for such waiver, the party benefiting
therefrom, if it desires to have the waiver, agrees to pay to the other the
amount of such additional premium promptly upon being billed therefor.

any public or quasi-public use, this Lease shall cease and terminate, and all

award specifically to Tenant as described in Section 11.01 above, shall be
retained by Landlord. For the purposes of this Section, a taking of the whole or
materially all of the Premises shall be deemed to have occurred if the portion
of the Premises not so taken, in Landlord's reasonable, good faith judgment,
cannot be reconstructed or repaired so as to constitute a facility usable by
Tenant for the purposes which the Premises were being used by Tenant immediately
prior to such taking.

to less than the whole or materially all of the Premises shall be taken in
Condemnation Proceedings, all the award or proceeds collected by Landlord
pursuant to Section 11.01 hereof shall be held by Landlord and applied and paid
over toward the cost of demolition, repair and restoration, substantially in the
same manner and subject to the same conditions as those provided in Section
10.03 hereof with respect to insurance and other monies and provided no Event of
Default shall have occurred. Any balance remaining in the hands of Landlord
after payment of such costs of demolition, repair and restoration as
aforementioned shall be the sole property of Landlord. This Lease shall continue
in full force and effect; provided however, the Fixed Basic Rent shall be
reduced by the proportion that the square footage of the Building taken in
condemnation bears to the total square footage of the Building.

or Additional Rent, or any part thereof, when the same shall become due and
payable for a period of ten (10) business days after written notice to Tenant
from Landlord; or

          (e)  if Tenant shall abandon the Premises, without the prior consent

          (a)  To accelerate the whole or any part of the Fixed Basic Rent for
the remainder of the Term (the "Accelerated Rent"), which Accelerated Rent shall
be discounted to present value on the basis of a discount rate equal to the
prime rate offered by CoreStates Bank, N.A., applied and calculated on the date
of receipt by Landlord of such Accelerated Rent; and shall be deemed due and
payable as if, by the terms and provisions of this Lease, such Accelerated Rent
was on that date payable in advance.

          (b)  Without waiving Landlord's right to recover the Accelerated Rent
as herein provided, Landlord may re-enter the Premises, and, at the option of
Landlord, remove all persons and all or any property therefrom, either by
summary dispossess proceedings or by any suitable action or proceeding at law or

seem advisable and to such person or persons as may in Landlord's discretion
seem best; upon each such reletting all rents received by Landlord from such
reletting shall be applied:  first, to the payment of any costs and expenses of
such reletting, including brokerage fees and attorney's fees and all costs of
such alterations and repairs; second, to the payment of any indebtedness other
than Fixed Basic Rent due hereunder from Tenant to Landlord; third, to the
payment of Additional Rent due and unpaid hereunder; and the residue, if any,
shall be held by Landlord and applied in payment of future rent as it may become
due and payable hereunder.  If such rentals received from such reletting during
any month shall be less than that to be paid during that month by Tenant, Tenant
shall pay any such deficiency to Landlord.  Such deficiency shall be calculated
and paid monthly.  No such re-entry or taking possession of the Premises or the
making of alterations or improvements thereto or the reletting thereof shall be
construed as an election on the part of Landlord to terminate this Lease unless
written notice of such intention be given to Tenant.  Landlord shall in no event
be liable in any way whatsoever for failure to relet the Premises, or in the
event that the Premises or any portion thereof is relet, for failure to collect
the rent thereof under such reletting. Notwithstanding any such reletting
without termination, Landlord may at any time thereafter elect to terminate this
Lease for such previous breach.

          (c)  Without waiving Landlord's right to recover the Accelerated Rent
as herein provided, Landlord may terminate the Lease and thereupon all rights of
Tenant under this Lease shall expire and terminate and Tenant shall forthwith
quit and surrender possession of the Premises in the condition specified in
Section 8.01 hereof.

     Section 12.03.  Non-Waiver.  No waiver by Landlord of any breach by Tenant
                     ----------
or any of Tenant's obligations, agreements or covenants herein shall be a waiver
of any subsequent breach, 

                                      19

nor shall any forbearance by Landlord to seek a remedy for any breach by Tenant
be a waiver by Landlord of any rights and remedies with respect to any
subsequent breach.

     Section 12.04.  Rights and Remedies Cumulative.  No right or remedy
                     ------------------------------
herein conferred upon or reserved to Landlord is intended to be exclusive of any
other right or remedy provided herein or by law, but each shall be cumulative
and in addition to every other right or remedy given herein or now or hereafter
existing at law or in equity or by statute.

MATTER WHATSOEVER ARISING OUT OF OR IN ANY WAY CONNECTED WITH THIS LEASE, THE
RELATIONSHIP OF LANDLORD AND TENANT, TENANT'S USE OF OR OCCUPANCY OF THE
PREMISES AND/OR ANY CLAIM OF INJURY OR DAMAGE OR REMEDY.

hereof upon the part of Tenant to be performed and observed, shall and may
peaceably hold and enjoy the said Premises during the term hereof, without any
interruption or disturbance from Landlord or anyone claiming by, through or
under Landlord, subject, however, to the terms of this Lease and subject to all
matters which now affect the Premises and subject to the rights of Landlord's
mortgage lenders under all present and future mortgages of Landlord covering the
Premises. This covenant shall be construed as running with the land to and
against subsequent owners and successors in interest, and is not, nor shall it
operate or be construed as, a personal covenant of Landlord, except to the
extent of Landlord's interest in said Premises and only so long as such interest
shall continue, and thereafter this covenant shall be binding only upon such
subsequent owners and successors in interest, to the extent of their respective
interests, as and when they shall acquire the same, and only so long as they
shall retain such interest.

     Section 13.02.  Subordination, Non-Disturbance and Attornment. This Lease,

pursuant to Article 15 hereof, shall not be subject or subordinate to the lien

writing, which contains a provision that so long as Tenant shall not be in
default under the terms of the Lease, the Lease, the Option and all of Tenant's
other rights hereunder, and Tenant attorns to such encumbrancer, the Lease shall
remain in full force and effect regardless of any event of foreclosure or
termination upon any such mortgage, ground lease or other encumbrance. Such
agreement shall also contain a provision, which obligates Tenant,
notwithstanding any claim, defense or right of setoff that otherwise may be
available to

similar writing, certifying to Landlord's mortgagee or purchaser such facts, if
true, and agreeing to such notice provisions and other matters as such mortgagee
or purchaser may reasonably require in connection with Landlord's present or
future financing or sale of the Building.

     Section 13.04.  Landlord's Lien Waiver.  Within thirty (30) days following

the written request of Tenant, Landlord shall execute a waiver or similar
writing, as may be reasonably required in connection with any present or future

defined under the Uniform Commercial Code), which are now or hereafter located
or stored on, or otherwise do now or hereafter pertain to, the Premises, and
which are subject to a security interest or lease agreement granted or entered
into by Tenant in favor of any creditor of Tenant (collectively, such items are
referred to as the "Collateral").. Landlord shall not take custody or possession
of the Collateral, or distrain or remove any of the Collateral from the
Premises, or interfere with the shipment, removal or delivery of any Collateral
to or from the Premises by Tenant (or any third party acting with Tenant's
permission), without having first provided thirty (30) days written notice of
such proposed action to any such creditor of Tenant to whom Landlord shall have
previously delivered a waiver or similar writing.

     Section 15.01.  Tenant's Option to Purchase.  In consideration of 
                     ---------------------------
Tenant's acceptance of this Lease, Tenant is hereby granted the exclusive right
and option to purchase the Building, together with all of all those certain
parcels and tracts of land on which the Building is situate, and all of
Landlord's estate, right, title and interest thereto, including all easements
and appurtenances thereto (collectively, the "Real Estate"), at any time prior
to Lease Year 3, provided the Lease is then in full force and effect (the
"Option"). The Option is to be exercised by Tenant's giving written notice of
its intention to purchase the Real Estate to Landlord not less than sixty (60)
days prior to Lease Year 3. This Lease and the aforesaid notice of Tenant's
exercise of the Option shall constitute an agreement of sale between the
parties, whereby Landlord agrees to sell and Tenant agrees to purchase the Real
Estate upon the following terms and conditions:

          (a)  Settlement for the purchase of the Real Estate shall be on the
earlier of (i) the date designated in Tenant's notice, which date shall be not
less than thirty (30) days after the date such notice is delivered to Landlord,
or (ii)  the commencement date of Lease Year 3.  Settlement shall occur in the
office of Tenant's title insurance company, on such date as shall be designated
in the aforesaid notice from Tenant to Landlord.

          (b)  In the event that Tenant effectively exercises the Option, the
purchase price for the Real Estate shall be equal to the sum of $6,500,000.00,
plus $21,000.00 multiplied by the number of full calendar months occurring after
the first full calendar month of Lease Year 1 and before the calendar month
during which settlement occurs, but including a pro rated portion of the $21,000
for the calendar month during which settlement occurs; provided however, that in
the event that settlement is delayed through no fault of Tenant, the purchase

                                      22
<PAGE>
 
price shall be calculated as if settlement had occurred on the date designated
in Tenant's notice; and provided further that in no event shall the purchase
price exceed the sum of $7,000,000.00.

          (c)  The purchase price, computed as above provided, shall be payable
by Tenant to Landlord, or to Landlord's mortgage lender if required by such
lender, at the time of settlement, by title company check, cashier's check,
certified check, or other immediately available funds.

          (d)  Tenant and Landlord shall each pay fifty percent (50%) of all
realty transfer taxes, documentary stamp taxes or other taxes and charges
imposed by the federal, state or local authorities upon the conveyance.

          (e)  Landlord shall convey to Tenant a good and marketable fee simple
title to the Real Estate, free and clear of all liens, encumbrances, easements,
restrictions or other exceptions or objections, except for the Permitted
Exceptions, and except as have been created or consented to by Tenant during the
term of this Lease.  Tenant's title shall be insurable as such at ordinary rates
by Commonwealth Land Title Insurance Company or such other title insurance
company selected by Tenant.  Except for Landlord's special warranty contained in
the deed conveying the Real Estate to Tenant, which warranty shall be subject to
the aforesaid permitted exceptions, Landlord shall make no representations or
warranties regarding the Real Estate.

          (f)  Tenant acknowledges that Tenant's obligation to purchase the Real
estate following the effective exercise of the Option shall not be subject to
Tenant's ability to obtain purchase money financing or any other contingency,
except for Landlord's obligation to deliver title to the Real estate as
aforesaid.  In the event Tenant fails to complete settlement for any reason
whatsoever, this Lease shall remain in full force and effect in accordance with
its terms, including the right to exercise the Renewal Options.  In the event
that Tenant is in default of its obligation to purchase the Real Estate, when
and as required hereunder, and such default is not cured within ten (10) days of
the date of such default, Tenant shall reimburse Landlord for Landlord's
reasonable costs and expenses actually incurred by Landlord in anticipation of
completing settlement, but in no event shall Tenant be obligated to reimburse
Landlord for more than $5,000.00.

     Section 15.02.  Tenant's Right of First Refusal.  Tenant's Landlord hereby
                     -------------------------------
grants to Tenant an exclusive right of first refusal to purchase the Real Estate
on the terms set forth in this Section 15.02. In the event that at any time
during the Term, and provided the Lease is then in full force and effect,
Landlord shall receive a bona fide offer to purchase all or any part of the Real
Estate, and desires to accept such offer, then Landlord shall promptly notify
Tenant in writing of such offer, such notice to specify the price, payment and
other material terms of such offer, and Landlord shall first offer to sell the
Real Estate or such portion of the Real Estate which is the subject of such
offer to Tenant on the same such terms. Tenant may accept such offer by written
notice to Landlord within fifteen (15) business days following the receipt of
Landlord's notice to Tenant. Upon Tenant's acceptance of such offer, closing
shall occur in accordance with the terms of the offer provided to Tenant by
Landlord. If Tenant does not agree to purchase the Real Estate 

                                      23
<PAGE>
 
or the subject portion thereof, Landlord shall have the right to proceed to sell
the Real Estate, or the subject portion thereof, pursuant to the terms of such
offer or on other terms no more favorable to the purchaser than were presented
to Tenant, subject to this Lease, the Option, and the other rights of Tenant
hereunder, and provided such sale is completed within the later of (i) 120 days
from the date Tenant gives notice that it does not elect to purchase the Real
Estate, or (ii) the period of time set forth in such offer. Notwithstanding
anything set forth herein to the contrary, Landlord shall not be permitted to
sell or convey the Real Estate during the first two years of the Term to anyone
but Tenant, except for a conveyance to a partnership, trust, or other legal
entity in which Brian O'Neill, an individual who presently owns an interest in
Landlord, shall continue to own a legal or beneficial interest, and with respect
to such conveyance Tenant's right of first refusal granted under this Section
shall not be deemed to be extinguished and the deed or other writing evidencing
such conveyance shall expressly provide that the conveyance and the grantee's
rights with respect thereto are and shall be subject to this Lease.

     Section 15.03.  Memorandum of Lease and Option to Purchase.  Concurrently
                     ------------------------------------------

memorandum of this lease and option to purchase in the form attached hereto as
Exhibit "D," which memorandum shall thereafter be promptly recorded in the

          (a)  Except as provided in paragraph (b) below, Tenant shall not
assign or sublet the Premises or any part thereof without Landlord's prior
written approval, which approval shall not be unreasonably withheld, conditioned
or delayed. If Tenant desires to assign this Lease or sublet any or all of the
Premises, Tenant shall give Landlord written notice prior to the anticipated
effective date of the assignment or sublease, and shall provide Landlord with a
written sublease or assignment, signed by each of Tenant and Tenant's assignee
or subtenant, and a copy of the most recently available financial statement for
such assignee or subtenant. Landlord shall then have a period of ten (10) days
following receipt of such notice to notify Tenant in writing that Landlord
elects either (1) to terminate this Lease as to the space so affected as of the
date so requested by Tenant, or (2) to permit Tenant to assign this Lease or
sublet such space. If Landlord shall fail to notify Tenant in writing of such
election within such period, Landlord shall be deemed to have approved such
assignment or sublease.

          (b)  Notwithstanding anything to the contrary contained in paragraph
(a) above, Tenant may assign or sublet all or any portion of the Premises if
either (A) (1) Tenant is not in default of any its obligations under this Lease,
(2) Tenant remains obligated hereunder, (3)

bound by all the terms and conditions of the Lease respecting the portion of the
Premises that is the subject of the assignment or sublease, or (B) (1) such

sublease or assignment in excess of Fixed Basic Rent payable hereunder, net of
the reasonable cost of any improvements which Tenant has made for the purpose of
assigning or subletting all or a part of the Premises and other expenses
incurred by Tenant associated with such assignment or subletting, including,
without limitation, brokerage commissions and legal fees, shall be divided and
paid, ten percent (10%) to Tenant, and ninety percent (90%) to Landlord.

          (d)  No assignment or subletting by Tenant shall relieve Tenant of any
obligations under this Lease. Any assignment of subletting which conflicts with
the provisions hereof shall be void.

      5.1  Corporate. IBAH is a corporation duly organized, validly existing and
in good standing under the laws under which it was incorporated and is qualified
to do business as a foreign corporation in any jurisdiction where it is required
to be so qualified, except where the failure to so qualify would not have a
Material Adverse Effect.  IBAH has the requisite power and authority to execute
and deliver the Transaction Documents to which it is a party and to perform the
Transactions to be performed by it, and such execution, delivery and performance
by IBAH have been duly authorized by all necessary corporate action.

      5.2  Authorization.  IBAH has the requisite power and authority to own its
Assets and to carry on its Business.  IBAH has the requisite power and authority
to execute and deliver the Transaction Documents to which it is a party and to
perform the Transactions performed or to be performed by it.  Such execution,
delivery and performance by IBAH has been duly authorized by all necessary
corporate action, other than approval by the stockholders of IBAH. Each
Transaction Document executed and delivered by IBAH has been duly executed and
delivered by, and constitutes a valid and binding obligation of IBAH,
enforceable against IBAH in accordance with its terms.

      5.3  IBAH Disclosure Documents.  IBAH has filed all required forms,
reports, statements, schedules and other documents with the SEC since the date
when it became subject to the reporting requirements under the 1934 Act
(collectively, the  IBAH Disclosure Documents"). IBAH has furnished to the
Selling Parties its Registration Statement on Form S-2, as amended, and the
final prospectus dated April 16, 1995 and Exhibits with respect to such
Registration Statement, its Registration Statement on Form S-3, as amended, and
the final prospectus dated December 16, 1996 and Exhibits with respect to such
Registration Statement as well as IBAH's Annual Report on Form 10-K for the

was filed, complied in all material respects with all applicable requirements of
the 1933 Act and the 1934 Act, and with the forms, rules and regulations of the
SEC promulgated thereunder, and did not contain at the time filed any untrue
statement of a material fact or omit to state any material fact required to be
stated therein or necessary in order to make the statements therein, in light of
the circumstances under which they are made, not misleading.
<PAGE>
 
      5.4  Consents and Approvals.  Neither the execution and delivery by IBAH
of the Transaction Documents to which it is a party, nor the performance of the
Transactions by IBAH, will require any filing, consent or approval or constitute
a Default under (a) any Law or Court Order to which IBAH is subject, (b) the
Charter Documents or bylaws of IBAH or (c) any Contract, Government Permit or
other document to which IBAH is a party or by which the properties or other
assets of such may be subject.

      5.5  Capitalization and Stock Ownership.  The total authorized capital
stock of IBAH consists of 50,000,000 shares of Common Stock, par value $0.01 per
share, approximately 22,141,562 shares of which are issued and outstanding and
2,000,000 shares of Series A Convertible Preferred Stock, par value $0.01 per
share, 749,665 of which are issued and outstanding.  Except for management
options issued in February 1997 pursuant to a management option plan, there are
no existing options, warrants, calls, commitments or other rights of any
character (including conversion or preemptive rights) relating to the
acquisition of any issued or unissued capital stock or other securities of IBAH.

complete copies of consolidated financial statements consisting of a balance

years then ended.  In addition, IBAH has delivered to the Seller correct and
complete copies of IBAH's unaudited monthly consolidated financial statements as
of the end of each month from July 1996 through September 1996.  The financial
statements as of and for the years ended December 31, 1994 and 1995 have been
audited by Arthur Andersen & Co LLP.  All of such audited and unaudited
financial statements, together with the notes to the audited financial
statements, are referred to herein as the "IBAH Financial Statements."  The IBAH
Financial Statements are consistent with the books and records of IBAH, and
there have not been any material transactions that have not been recorded in the
accounting records underlying the IBAH Financial Statements.  The IBAH Financial
Statements have been prepared in accordance with GAAP consistently applied
(subject in the case of the unaudited statements to year-end adjustments and the
absence of notes to the financial statements) and present accurately the
financial position and assets and liabilities of IBAH as of the dates thereof,
and the results of its operations for the periods then ended.

necessary in order to make the statements contained herein or therein not
misleading.

      Closing Date; and

           (e)  any and all actions, suits, claims, proceedings, investigations,
      demands, assessments, audits, fines, judgments, costs and other expenses
      (including without limitation reasonable attorneys' fees and expenses)
      incident to any of the foregoing or to the enforcement of this Section
      10.1.

      10.2 By IBAH.  From and after the Closing Date, to the extent provided in
this Section 10, IBAH shall indemnify and hold harmless the Seller, his
successors and assigns (each, an "Indemnified Party") from and against any
Damages that such Indemnified Party may sustain, suffer or incur and that result
from, arise out of or relate to any breach of any representation, warranty,
covenant or agreement of IBAH contained in this Agreement.

      10.3 Procedure for Claims.

          (a) An Indemnified Party that desires to seek indemnification under
any part of this Section 10 shall give notice (a "Claim Notice") to each party
responsible or alleged to be responsible for indemnification hereunder (an
"Indemnitor").  Such notice shall briefly explain the nature of the claim and
shall specify the amount thereof.  If the matter to which a claim relates shall
not have been resolved as of the date of the Claim Notice, the Indemnified Party
shall estimate the amount of the claim in the Claim Notice, but also specify
therein that the claim has not yet been liquidated (an "Unliquidated Claim").
If an Indemnified Party gives a Claim Notice for an Unliquidated Claim, the
Indemnified Party shall also give a second Claim Notice (the "Liquidated Claim
Notice") within 60 days after the matter giving rise to the claim becomes
finally resolved, and the Second Claim Notice shall specify the amount of the
claim.  Each Indemnitor to which a Claim Notice is given shall respond to any
Indemnified Party that has given a Claim Notice (a "Claim Response") within 20
days (the "Response Period") after the later of (i) the date that the Claim
Notice is given or (ii) if a Claim Notice is first given with respect to an
Unliquidated Claim, the date on which the Liquidated Claim Notice is given.  Any
Claim Notice or Claim Response shall be given in accordance with the notice
requirements hereunder, and any Claim Response shall specify whether or not the
Indemnitor giving the Claim Response disputes the claim described in the Claim
Notice.  If any Indemnitor fails to give a Claim Response within the Response
Period, such Indemnitor shall be deemed not to dispute the claim described in
the related Claim Notice.  If any Indemnitor elects not to dispute a claim
described in a Claim Notice, whether by failing to give a timely Claim Response
or otherwise, then the amount of such claim shall be conclusively deemed to be
an obligation of such Indemnitor.

          (b) If any Indemnitor shall be obligated to indemnify an Indemnified
Party hereunder, such Indemnitor shall pay to such Indemnified Party within 30
days after the last day of the Claim Response Period the amount to which such
Indemnified Party shall be entitled.  If  IBAH shall be the Indemnified Party,
it shall first request payment of the related Damages under the Escrow
Agreement, but only to the extent that Escrow Funds are then being held by the
Escrow Agent and are not subject to other claims for indemnification, and
thereafter IBAH shall seek 
<PAGE>
 
indemnification directly from the Selling Parties, including the offset of any
payments payable to Phillip Altman pursuant to the terms of the Altman
Employment Agreement. If there shall be a dispute as to the amount or manner of
indemnification under this Section 10, the Indemnified Party may pursue whatever
legal remedies may be available for recovery of the Damages claimed from any
Indemnitor. If any Indemnified Party fails to receive all or part of any
indemnification obligation when due, then such Indemnified Party shall also be
entitled to receive from the applicable Indemnitor or, if applicable, the Escrow
Agent, interest on the unpaid amount for each day during which the obligation
remains unpaid at an annual rate equal to the Prime Rate, and the Prime Rate in
effect on the first business day of each calendar quarter shall apply to the
amount of the unpaid obligation during such calendar quarter.

      10.4 Third Party Claims.  An Indemnified Party that desires to seek
indemnification under any part of this Section 10 with respect to any actions,
suits or other administrative or judicial proceedings (each, an "Action") that
may be instituted by a third party shall give each Indemnitor prompt notice of a
third party's institution of such Action.  After such notice, any Indemnitor
may, or if so requested by such Indemnified Party, any Indemnitor shall,
participate in such Action or assume the defense thereof, with counsel
satisfactory to such Indemnified Party; provided, however, that such Indemnified
Party shall have the right to participate at its own expense in the defense of
such Action; and provided, further, that the Indemnitor shall not consent to the
entry of any judgment or enter into any settlement, except with the written
consent of such Indemnified Party (which consent shall not be unreasonably
withheld), that (a) fails to include as an unconditional term thereof the giving
by the claimant or plaintiff to such Indemnified Party of a release from all
liability in respect of any such Action or (b) grants the claimant or plaintiff
any injunctive relief against the Indemnified Party.  Any failure to give prompt
notice under this Section 10.4 shall not bar an Indemnified Party's right to
claim indemnification under this Section 10, except to the extent that an
Indemnitor shall have been harmed by such failure.

      10.5 Survival of Representations and Warranties.  The representations and
warranties given or made by the Selling Parties and IBAH in this Agreement or in
any certificate or other writing furnished in connection herewith shall survive
the Closing indefinitely. Each party shall be entitled to rely upon the
representations and warranties of the other party or parties set forth herein
regardless of any investigation or audit conducted before or after the Closing
Date or the decision of any party to complete the Closing.

11.   Termination.

      11.1 When Agreement May be Terminated.  This Agreement may be terminated:

           (i) by mutual written consent of IBAH and Seller at any time prior to
Closing;

material respect its covenants or agreements contained herein required to be
performed on or prior to the Closing Date and such failure has not been cured
within five Business Days after written notice of such failure from the non-
breaching party;

          (iii) by IBAH if there is a net loss reflected in the Closing
Financial Statements and the parties have not been able to reach mutual
agreement on the amount of the reduction of the Purchase Price; or

          (iv)  by IBAH, if there shall have been a change in the Company's
Business that has had a Material Adverse Effect on the Company.

      11.2 Effect of Termination.  In the event of termination of this Agreement
by either IBAH or Seller, this Agreement shall immediately terminate and be of
no further force and effect.  Any party may pursue any legal or equitable
remedies that may be available if such termination is based on a breach of
another party.

                         REGISTRATION RIGHTS AGREEMENT
                        

    THIS AGREEMENT is made as of February 28, 1997 by and among IBAH, Inc., a
Delaware corporation (the "Company") and Catapult Pty., Ltd., an Australian
company (the "Holder").

                                   Background

    The Holder is acquiring on the date of Closing the number of shares of
Common Stock, par value $0.01 per share, of the Company (the "Common Stock")
required by Section 2.1 (d) of the Stock Purchase Agreement (defined below). The
Company has agreed to provide the registration rights provided for in this
Agreement as an inducement for the Holder to sell all of the capital stock of
Pharmaco US to the Company pursuant to the Stock Purchase Agreement, dated
February 28, 1997, by and among the Company, the Holder and Phillip Altman and
Juanita Altman (the "Stock Purchase Agreement"), and to enter into other
agreements contemporaneously with this Agreement.

                                  Witnesseth:

    The parties hereto, each intending to be legally bound and in exchange for
the mutual covenants herein, agree as follows:

1.  Inclusion in Offerings.  If, during the period beginning the date hereof and
ending 12 months from the date hereof (the  "First Registration Period"), the
Company or any security holder of the Company files a registration statement
with the Securities and Exchange Commission to register the Company's Common
Stock (a  "Registration"), other than (i) a registration statement on Form S-4,
(ii) a registration statement on Form S-8 or (ii) a registration statement in
connection with an underwritten public offering, the Company shall ensure that
all Registrable Securities shall be included in such Registration if so
requested by the Holders owning such Registrable Securities; provided, however,
that the Holders shall not be entitled under this Section 1 to have included in
a Registration Registrable Securities with a value (as determined by the price
at which such Registrable Securities are to be offered) greater than 25% of the
total number of the securities registered in such Registration.

2.  Demand Registrations.

    (a) Requests for Registration.  For the period beginning immediately
following the expiration of the First Registration Period and ending 12 months
thereafter, the Holders may demand registration (a "Demand Registration") under
the Securities Act of 1933, as amended (the "1933 Act"), of all or any part of
the Registrable Securities owned by such Holders.  In order to accomplish such
demand, the Holder shall send written notice of the demand to the Company, and
such notice shall specify the number of Registrable Securities sought to be
registered.  The Company shall only be required to effect one Demand
Registration.

    (b) Priority on Demand Registrations.  If a Demand Registration is
underwritten and the managing underwriters advise the Company in writing that in
their opinion the number of Registrable Securities requested to be included
exceeds the number that can be sold in such offering, at a price reasonably
related to fair value, the Company will 
<PAGE>
 
include in such Demand Registration (i) first, the Registrable Securities
requested to be included in such Demand Registration by the Holder; (ii) second,
any securities that the Company desires to include on its own behalf; and (iii)
third, any shares of Common Stock held by any other stockholder of the Company
to whom registration is offered.

    (c) Selection of Underwriters. If any Demand Registration is underwritten,
the selection of investment banker(s) and manager(s) and the other decisions
regarding the underwriting arrangements for the offering will be made by the
Company and the Holders participating in the Demand Registration.

    (d) Restrictions on Demand Registrations. The Company will not be obligated
to effect any Demand Registration within six months after the effective date of
a previous registration of securities of the Company in an underwritten
offering.

3.  Registration and Offering Expenses.  In connection with all registrations
and Offerings of Registrable Securities under this Agreement, the Company shall
pay the Registration Expenses (defined below) related to the Registrable
Securities of the Holders, but the Holders shall pay the Underwriting
Commissions (defined below), if any, related to their Registrable Securities.

4.  Holdback Agreements.  The Holders shall not effect any public sale or
distribution of equity securities of the Company or any securities convertible
into or exchangeable or exercisable for such securities during a period prior to
and after any underwritten offering is consummated (except as part of such
Offering) that is determined by the underwriters of such offering.

5.  Indemnification.

    (a) The Company shall indemnify, to the extent permitted by law, each
Holder, its officers and directors, and each person who controls such holder
(within the meaning of the 1933 Act or the Securities Exchange Act of 1934, as
amended ("the 1934 Act")) (each, a "Holder Indemnitee"), against all losses,
claims, damages, liabilities and expenses arising out of or resulting from any
untrue or alleged untrue statement of material fact contained in any
registration statement, prospectus or preliminary prospectus or any omission or
alleged omission to state therein a material fact required to be stated therein
or necessary to make the statements therein not misleading except insofar as the
same are caused by or contained in any information furnished in writing to the
Company by such Holder Indemnitee, acting in its capacity as a stockholder (or
an officer, director or controller of a stockholder) expressly for use therein
or by any such Holder Indemnitee's failure to deliver a copy of the registration
statement or prospectus or any amendments or supplements thereto after the
Company has furnished such Holder Indemnitee with a sufficient number of copies
of the same.

    (b) In connection with any registration statement in which a Holder is
participating, each such Holder shall furnish to the Company in writing such
information as is reasonably requested by the Company for use in any such
registration statement or prospectus and shall indemnify, to the extent
permitted by law, the Company, its directors and officers and each person who
controls the Company (within the meaning of the 1933 Act or the 1934 Act)
against any losses, claims, damages, liabilities and expenses resulting from any
untrue or alleged untrue statement of material fact or any omission or alleged
omission of a material fact required to be stated in the registration statement
or 
<PAGE>
 
prospectus or any amendment thereof or supplement thereto or necessary to make
the statements therein not misleading, but only to the extent that such untrue
statement or omission is contained in information so furnished in writing by
such Holder (i) specifically for use in preparing the registration statement and
(ii) in such Holder's capacity as a stockholder of the Company, and not in such
Holder s capacity as an officer, director or employee of the Company.

    (c) Any person entitled to indemnification hereunder shall (i) give prompt
notice to the indemnifying party of any claim with respect to which it seeks
indemnification and (ii) unless in such indemnified party's reasonable judgment
a conflict of interest between such indemnified and indemnifying parties may
exist with respect to such claim, permit such indemnifying party to assume the
defense of such claim with counsel reasonably satisfactory to the indemnified
party. If such defense is assumed, the indemnifying party shall not be subject
to any liability for any settlement made without its consent (but such consent
will not be unreasonably withheld). An indemnifying party who is not entitled,
or elects not, to assume the defense of a claim shall not be obligated to pay
the fees and expenses of more than one counsel for all parties indemnified by
such indemnifying party with respect to such claim, unless in the reasonable
judgment of any indemnified party a conflict of interest may exist between such
indemnified party and any other of such indemnified parties with respect to such
claim.

6.  Definitions.

    (a) The term "Registrable Securities" means (i) the shares of Common Stock
registered in the names of the Holders and listed beside each Holder's name on
Appendix A hereto and (ii) any securities issued or to be issued with respect to
the securities referred to above by way of a stock dividend or stock split or in
connection with a combination of shares, recapitalization, merger, consolidation
or other reorganization.  As to any particular Registrable Securities, such
securities will cease to be Registrable Securities when they have been (A)
effectively registered under the 1933 Act and disposed of in accordance with the
registration statement covering them, or (B) transferred pursuant to Rule 144
(or any similar provision then in force).

    (b) The term "Registration Expenses" means all expenses incident to the
Company's performance of or compliance with this Agreement, including all
registration and filing fees, fees and expenses of compliance with securities or
blue sky laws, printing expenses, messenger and delivery expenses, expenses and
fees for listing the securities to be registered on exchanges on which similar
securities issued by the Company are then listed, and fees and disbursements of
counsel for the Company and of all independent certified public accountants,
underwriters (other than Underwriting Commissions) and other persons retained by
the Company.

    (c) The term "Underwriting Commissions" means all underwriting discounts or
commissions relating to the sale of securities of the Company, but excludes any
expenses reimbursed to underwriters.

7.  Miscellaneous.

    (a) Notices.  Any notices required hereunder shall be deemed to be given
upon the earlier of the date when received at, or the seventh day after the date
when sent by certified or registered mail to, the address of the Company's
corporate headquarters in the 
<PAGE>
 
case of any notice to the Company, and until changed by notice to the Company,
the respective addresses of the Holders on file with the Company in the case of
any notice to the Holders.

     (b) Amendments and Waivers.  The provisions of this Agreement may be
amended or terminated and the Company may take any action herein prohibited, or
omit to perform any act herein required to be performed by it, if approved in
writing by the Holders that own beneficially two-thirds of the Registrable
Securities.

     (c) Binding Effect.  This Agreement will bind and inure to the benefit of
the respective successors (including any successor resulting from a merger or
similar reorganization), assigns, heirs, and personal representatives of the
parties hereto.

     (d) Governing Law.  All questions concerning the construction, validity and
interpretation of this Agreement will be governed by the internal law, not the
law of conflicts, of Delaware.

     (e) Counterparts.  This Agreement may be executed in any number of
counterparts, each of which shall be considered to be an original instrument and
to be effective as of the date first written above.  Each such copy shall be
deemed an original, and it shall not be necessary in making proof of this
Agreement to produce or account for more than one such counterpart.

     (f) Interpretation.  Unless the context of this Agreement clearly requires
otherwise, (a) references to the plural include the singular, the singular the
plural, the part the whole, (b) references to one gender include all genders,
(c) "or" has the inclusive meaning frequently identified with the phrase
"and/or" and (d) "including" has the inclusive meaning frequently identified
with the phrase "but not limited to."  The section and other headings contained
in this Agreement are for reference purposes only and shall not control or
affect the construction of this Agreement or the interpretation thereof in any
respect.

     IN WITNESS WHEREOF, the parties hereto, intending to be legally bound, have
hereunto duly executed this Agreement the day and year first written above.

                              AGREEMENT OF MERGER
                              -------------------


     This Agreement of Merger (the "Agreement") is made and entered into as of 
July 18, 1996, by and between Resource Biometrics, Inc., a California 
corporation ("RBI") and IBAH Acquisition Company, a California corporation 
("IBAH"), and IBAH, Inc., a Delaware corporation ("IBAH, Inc.").


                                R E C I T A L S
                                ---------------

     A.   Prior to the execution of this Agreement, IBAH, IBAH, Inc., and RBI 
have entered into an Agreement and Plan of Merger dated July 18, 1996, (the 
"Plan") providing for, among other things, the execution and delivery of this 
Agreement, the merger of RBI with and into IBAH, and for the issuance of shares 
of the Common stock of IBAH, Inc. ("IBAH, Inc. Common Stock") upon the terms set
forth in the Plan and this Agreement.

     B.   The respective Boards of Directors of IBAH, RBI, and IBAH, Inc. and 
the shareholders of RBI have determined that it is in the best interests of 
their respective corporations that RBI be merged with and into IBAH in a 
statutory merger pursuant to the Plan and this Agreement and in accordance with 
California law and that upon the effective date of such merger (the "Merger") 
the outstanding shares of RBI Common Stock shall be converted into shares of 
IBAH, Inc. Common Stock pursuant to the terms and conditions of this Agreement 
and the Plan.

     C.   The parties intend the Plan and Merger to qualify as a tax free plan 
of reorganization pursuant to the provisions of Section 368(a)(2)(D) of the 
Internal Revenue Code of 1954, as amended.

     NOW, THEREFORE, in consideration of the foregoing premises and the mutual 
agreements, representations, and warranties contained herein, the parties agree 
as follows:

     1.   Effective Date of Merger.  The Merger shall become effective when this
          ------------------------
Agreement and the Officer's Certificates of the Corporations are filed with the
Secretary of State of the State of California as required by Section 1103 of the
California Corporations Code.  The date on which the merger shall become 
effective is referred to herein as "the Effective Date."

     2.   Effect of Merger.  On the Effective Date, RBI shall be merged with and
          ----------------
into IBAH pursuant to the terms and conditions of this Agreement and in 
accordance

                                      -1-



  
<PAGE>
 
with the applicable provisions of California law and IBAH shall continue in
existence as the surviving corporation (the "Surviving Corporation"). The
corporate identity, existence, purposes, powers, rights, and immunities of IBAH
as the Surviving Corporation shall continue unaffected and unimpaired by the
Merger. The separate existence and corporate organization of RBI shall cease on
the Effective Date and IBAH shall succeed to and possess all the properties,
rights, privileges, powers, franchises, immunities and purposes, and be subject
to all the debts, liabilities, obligations, restrictions, disabilities,
penalties and duties of Subsidiary, by operation of law without further act or
deed.

     3.   Further Acts.  Notwithstanding the above, after the Effective Date the
          ------------
proper officers and directors of RBI may perform any acts necessary of desirable
to vest or confirm IBAH's possession of and title to any property or rights of
RBI, or otherwise carry out this Agreement's purposes. This shall include
execution and delivery of documents, assurances, assignments, or other
instruments.

     4.   Articles of Incorporation.  From and after the Effective Date, the 
          -------------------------
articles of incorporation of IBAH in effect immediately prior to the Effective 
Date shall be the articles of incorporation of the Surviving Corporation. The 
shareholder(s) and director(s) of IBAH shall amend the articles of incorporation
to change the name of the Surviving Corporation to Resource Biometrics, Inc.
