SUMMARY

     The following summary is qualified in its entirety by the more
detailed information appearing elsewhere or incorporated by reference in
this Prospectus.  This Prospectus may contain certain "forward-looking"
information, as that term is defined by (i) the Private Securities
Litigation Reform Act of 1995 (the "Act") and (ii) releases made by the
Securities and Exchange Commission.  Such information involves risks and
uncertainties.  The Company's actual results may differ materially from the
results discussed in the forward-looking statements.  Factors that might
cause such a difference include, but are not limited to, those discussed in
"Risk Factors."  In December 1997, the Company acquired Kemper-Masterson,
Inc. ("KMI") in a business combination accounted for as a pooling of
interests.  The accompanying supplemental consolidated financial statements
have been retroactively restated to combine the accounts and operations of
KMI with those of the Company for all periods presented.


THE COMPANY

PAREXEL International Corporation ("PAREXEL" or the "Company") is a leading
contract research organization ("CRO") providing a broad range of knowledge-
based product development and product launch services to the worldwide
pharmaceutical, biotechnology and medical device industries.  The Company's
primary objective is to help clients quickly obtain the necessary
regulatory approvals of their products and, ultimately, optimize the market
penetration of those products.  Over the past fifteen years, PAREXEL has
developed significant expertise in disciplines supporting this strategy.
The Company's service offerings include:  clinical trials management, data
management, biostatistical analysis, medical marketing, clinical
pharmacology, regulatory and medical consulting, performance improvement,
industry training and publishing, and other drug development consulting
services.  The Company believes that its integrated services, therapeutic
area depth, and sophisticated information technology, along with its
experience in global drug development and product launch services,
represent key competitive strengths.

The Company complements the research and development ("R&D") functions, as
well as the marketing functions, of pharmaceutical and biotechnology
companies.  Through its high quality clinical research and medical
marketing services, PAREXEL helps clients maximize the return on their
significant investments in research and development by reducing the time
and cost of clinically testing their products and launching those products
into the commercial marketplace.  By outsourcing these types of services,
clients are provided with a variable cost alternative to the fixed costs
associated with internal drug development and product marketing.  Clients
no longer need to staff to peak periods, and can benefit from PAREXEL's
technical resource pool, broad therapeutic area expertise, global
infrastructure designed to expedite parallel, multi-country clinical
trials, and other expertise-oriented advisory services focused on
accelerating time-to-market.

Headquartered near Boston, Massachusetts, the Company has 25 offices in 10
countries, and employs over 3,000 individuals.  The Company has established
footholds in the major health care markets around the world, including the
United States, Japan, Germany, the United Kingdom ("U.K."), France, Italy,
Spain, Sweden, Australia, and Israel. During fiscal 1997, PAREXEL derived
33% of its revenues from its international operations, distinguishing the
Company from many of its competitors.

The CRO industry derives substantially all of its revenue from the
pharmaceutical and biotechnology industries. The Company believes that the
following trends will cause the CRO industry to continue to grow: (i) the
worldwide research and development expenditures for new drugs, including
amounts spent on services of the type provided by CROs, have experienced
substantial growth in recent years as a result of pressures to develop new
drugs for an aging population and for the treatment of life threatening
diseases and chronic disorders; (ii) many pharmaceutical companies, in
response to competitive pressures to accelerate time to market and contain
costs, have turned to CROs as a means of adding more flexible drug
development capacity to accommodate their full product pipelines, thereby
shifting fixed costs to variable costs; (iii) pharmaceutical and
biotechnology companies increasingly are attempting to maximize profits
from a given drug by pursuing regulatory approvals in multiple countries in
parallel, rather than sequentially, by outsourcing to CROs with global
capabilities; (iv) as regulatory requirements in many jurisdictions have
become more complex, the pharmaceutical and biotechnology industries are
increasingly outsourcing to certain CROs to take advantage of their
regulatory expertise, data management capabilities and global presence; and
(v) the growth of the biotechnology industry has increased the demand for
expertise and services provided by outside sources, including CROs.  There
can be no assurance, however, that these trends will result in growth in
the CRO industry.

Central to PAREXEL's success has been the Company's focused strategy on
building its platform of knowledge in the pursuit of outstanding client
service.  This includes a focus on its core clinical research business; a
focus on continuous process improvement, efficiency gains and leveraging
internal expertise, resources and infrastructure; a focus on managing the
Company's strong internal growth while augmenting the Company's knowledge
base through strategic acquisitions; a focus on deeply and broadly
penetrating key client accounts by offering a full spectrum of clinical
development and medical marketing services; and always, a focus on
outstanding quality and superior client service.

The Company's service philosophy involves a flexible approach which allows
its clients to use the Company's services on an individual or bundled
basis.  The Company believes its expertise in conducting scientifically
demanding trials and its ability to coordinate complicated global trials
are significant competitive strengths. The Company continues to devote
significant resources to developing innovative methodologies and
sophisticated information systems designed to allow the Company to more
effectively manage its business operations and deliver services to its
clients.  The Company has executed a focused growth strategy embracing
internal expansion and strategic acquisitions to expand or enhance the
Company's portfolio of services, geographic presence, therapeutic area
knowledge, information technology, and client relationships.

The Company was incorporated in The Commonwealth of Massachusetts in 1983.
Unless the context otherwise requires, the terms "PAREXEL" and "the
Company" refer to PAREXEL International Corporation and its subsidiaries.
The Company's principal executive offices are located at 195 West Street,
Waltham, Massachusetts 02154, and its telephone number is (781) 487-9900.

RECENT DEVELOPMENTS

     KMI Merger.   Pursuant to an Agreement and Plan of Reorganization and
Merger dated October 22, 1997 by and among the Company, Kemper-Masterson,
Inc., a Delaware corporation ("KMI"), KMI Acquisition Corporation, a
Massachusetts corporation and a wholly-owned subsidiary of the Company, and
the individual stockholders named therein (the "Merger Agreement"), KMI
Acquisition Corporation merged with and into KMI and KMI became a wholly-
owned subsidiary of the Company (the "KMI Merger").  In connection with the
KMI Merger, the Company issued an aggregate of 581,817 shares of Common
Stock to the stockholders of KMI, of which 290,909 shares are being offered
hereby.  PAREXEL is obligated to use commercially reasonable efforts to
maintain the effectiveness of this Registration Statement until October 22,
1998, subject to certain conditions and limitations set forth in a
Registration Rights Agreement among the Company and the former stockholders
of KMI.  Pursuant to the terms and provisions of the Registration Rights
Agreement, the Company has agreed to register the remaining 290,908 shares
of Common Stock issued to such former stockholders of KMI approximately 180
days after the date of this Prospectus.  The KMI Merger is intended to
qualify as a reorganization under Section 368 of the Internal Revenue Code
of 1986, as amended.  The Merger has been accounted for as a pooling of
interests for financial accounting purposes.

     KMI is a management consulting firm providing consulting services on
FDA and other regulatory matters to the worldwide pharmaceutical,
biotechnology and medical device industries.

     Hayden Acquisition.  Pursuant to an Asset Purchase Agreement by and
among the Company, Perceptive Systems, Inc., a Colorado corporation doing
business as Hayden Image Processing Group ("Hayden"), and Howard W. Foster,
the sole stockholder of Hayden, (the "Asset Purchase Agreement"), the
Company acquired substantially all of the assets of Hayden in exchange for
shares of the Company's Common Stock (the "Hayden Acquisition").  In
connection with the closing of the Hayden Acquisition, the Company issued
5,035 shares of Common Stock to Hayden as consideration for the sale of
assets, all of which are being offered hereby.  In connection with the
anticipated dissolution of Hayden, the 5,035 shares of Common Stock issued
to Hayden were subsequently transferred to Howard W. Foster, the sole
stockholder of Hayden.  As additional consideration for the Hayden
Acquisition and pursuant to the Asset Purchase Agreement, the Company has
agreed to issue additional shares of Common Stock, with a value in the
aggregate not to exceed $228,000, over a three year period representing
contingent payments calculated as a percentage of net receipts received by
the Company and attributable to certain of the assets purchased in
connection with the Hayden Acquisition (the "Contingent Shares").  Pursuant
to the terms and provisions of a Registration Rights Agreement between the
Company and Hayden, the Company has granted certain "piggyback" rights with
respect to the Contingent Shares which would allow the registration of the
Contingent Shares on future registration statements filed by the Company.
The Hayden Acquisition has been accounted for as a purchase for financial
accounting purposes. Hayden developed, serviced and sold software products
that enable radiologists to measure and analyze high resolution medical
images, such as x-rays and magnetic resonance images.

RISK FACTORS

In addition to the other information in this Registration Statement, the
following risk factors should be considered carefully in evaluating the
Company and its business. Information provided by the Company from time to
time may contain certain "forward-looking" information, as that term is
defined by (i) the Private Securities Litigation Reform Act of 1995 (the
"Act") and (ii) in releases made by the Securities and Exchange Commission
(the "SEC"). These risk factors are being provided pursuant to the
provisions of the Act and with the intention of obtaining the benefits of
the "safe harbor" provisions of the Act.

Loss or Delay of Large Contracts

Most of the Company's contracts are terminable upon 60 to 90 days' notice
by the client. 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 undesired clinical results of
the product, the client's decision to forego a particular study, such as
for economic reasons, insufficient patient enrollment or investigator
recruitment or production problems resulting in shortages of the drug. In
addition, the Company believes that cost-containment and competitive
pressures have caused pharmaceutical companies to apply more stringent
criteria to the decision to proceed with clinical trials and therefore may
result in a greater willingness of these companies to cancel contracts with
CROs. The loss or delay of a large contract or the loss or delay of
multiple contracts could have a material adverse effect on the financial
performance of the Company.

Variability of Quarterly Operating Results

The Company's quarterly operating results have been subject to variation,
and will continue to be subject to variation, depending upon factors such
as the initiation, progress, or cancellation of significant projects,
exchange rate fluctuations, the mix of services offered, the opening of new
offices and other internal expansion costs, the costs associated with
integrating acquisitions and the startup costs incurred in connection with
the introduction of new products and services. In addition, during the
third quarter of fiscal 1995 and 1993, the Company's results of operations
were affected by a noncash write-down due to the impairment of long-lived
assets and a noncash restructuring charge, respectively. See "Risks
Associated with Acquisitions." Because a high percentage of the Company's
operating costs are relatively fixed, variations in the initiation,
completion, delay or loss of contracts, or in the progress of client
projects can cause material adverse variations in quarterly operating
results.

Dependence on Certain Industries and Clients

The Company's revenues are highly dependent on research and development
expenditures by the pharmaceutical and biotechnology industries. The
Company's operations could be materially and adversely affected by general
economic downturns in its clients' industries, the impact of the current
trend toward consolidation in these industries or any decrease in research
and development expenditures. Furthermore, the Company has benefited to
date from the increasing tendency of pharmaceutical companies to outsource
large clinical research projects. A reversal or slowing of this trend would
have a material adverse effect on the Company. In fiscal 1997, 1996, and
1995, and the three months ended September 30, 1997, the Company's top five
clients accounted for 39%, 30%, 23%, and 37%, respectively, of the
Company's consolidated net revenue. For the three months ended September
30, 1997, one client accounted for 16% of the Company's net revenue.  In
fiscal 1997, 1996, and 1995, no single customer accounted for more than 10%
of net revenue.  The loss of business from a significant client could have
a material adverse effect on the Company.

Management of Business Expansion; Need for Improved Systems; Assimilation
of Foreign Operations

The Company's business and operations have experienced substantial
expansion over the past 15 years. The Company believes that such expansion
places a strain on operational, human and financial resources. In order to
manage such expansion, the Company must continue to improve its operating,
administrative and information systems, accurately predict its future
personnel and resource needs to meet client contract commitments, track the
progress of ongoing client projects and attract and retain qualified
management, professional, scientific and technical operating personnel.
Expansion of foreign operations also may involve the additional risks of
assimilating differences in foreign business practices, hiring and
retaining qualified personnel, and overcoming language barriers. In the
event that the operation of an acquired business does not live up to
expectations, the Company may be required to restructure the acquired
business or write-off the value of some or all of the assets of the
acquired business. Failure by the Company to meet the demands of and to
manage expansion of its business and operations could have a material
adverse effect on the Company's business.

Risks Associated with Acquisitions

The Company has made a number of acquisitions and will continue to review
future acquisition opportunities. No assurances can be given that
acquisition candidates will continue to be available on terms and
conditions acceptable to the Company. Acquisitions involve numerous risks,
including, among other things, difficulties and expenses incurred in
connection with the acquisitions and the subsequent assimilation of the
operations and services or products of the acquired companies, the
diversion of management's attention from other business concerns and the
potential loss of key employees of the acquired company. Acquisitions of
foreign companies also may involve the additional risks of assimilating
differences in foreign business practices and overcoming language barriers.
In the event that the operations of an acquired business do not live up to
expectations, the Company may be required to restructure the acquired
business or write-off the value of some or all of the assets of the
acquired business. In fiscal 1993 and 1995, the Company's results of
operations were materially and adversely affected by write-offs associated
with the Company's acquired German operations. There can be no assurance
that any acquisition will be successfully integrated into the Company's
operations.

Dependence on Government Regulation

The Company's business depends on the comprehensive government regulation
of the drug development process. In the United States, the general trend
has been in the direction of continued or increased regulation, although
the FDA recently announced regulatory changes intended to streamline the
approval process for biotechnology products by applying the same standards
as are in effect for conventional drugs. In Europe, the general trend has
been toward coordination of common standards for clinical testing of new
drugs, leading to changes in the various requirements currently imposed by
each country. Japan also legislated GCP and legitimatized the use of CRO's
in April 1997. Changes in regulation, including a relaxation in regulatory
requirements or the introduction of simplified drug approval procedures, as
well as anticipated regulation, could materially and adversely affect the
demand for the services offered by the Company. In addition, failure on the
part of the Company to comply with applicable regulations could result in
the termination of ongoing research or the disqualification of data, either
of which could have a material adverse effect on the Company.


Competition; CRO Industry Consolidation

The Company primarily competes against in-house departments of
pharmaceutical companies, full service CROs, and, to a lesser extent,
universities, teaching hospitals and other site organizations. Some of
these competitors have greater capital, technical and other resources than
the Company. CROs generally compete on the basis of previous experience,
medical and scientific expertise in specific therapeutic areas, the quality
of services, the ability to organize and manage large-scale trials on a
global basis, the ability to manage large and complex medical databases,
the ability to provide statistical and regulatory services, the ability to
recruit investigators and patients, the ability to integrate information
technology with systems to improve the efficiency of contract research, an
international presence with strategically located facilities, financial
viability and price. PAREXEL believes that it competes favorably in these
areas. There can be no assurance that the Company will be able to compete
favorably in these areas.

The CRO industry is fragmented, with participants ranging from several
hundred small, limited-service providers to several large, full-service
CROs with global operations. Large CROs against whom PAREXEL competes
include Quintiles Transnational Corporation, Covance Inc., IBAH, Inc.,
Pharmaceutical Product Development, Inc. and ClinTrials Research, Inc. The
trend toward CRO industry consolidation has resulted in heightened
competition among the larger CROs for clients and acquisition candidates.
In addition, consolidation within the pharmaceutical industry as well
pharmaceutical companies outsourcing to a fewer number of preferred CROs
has led to heightened competition for CRO contracts.

Potential Volatility of Stock Price

The market price of the Company's Common Stock could be subject to wide
fluctuations in response to quarter-to-quarter variations in operating
results, changes in earnings estimates by analysts, market conditions in
the industry, prospects of health care reform, changes in government
regulation and general economic conditions. In addition, the stock market
has from time to time experienced significant price and volume fluctuations
that have been unrelated to the operating performance of particular
companies. These market fluctuations may adversely affect the market price
of the Company's Common Stock. Because the Company's Common Stock currently
trades at a relatively high price-earnings multiple, due in part to
analysts' expectations of continued earnings growth, even a relatively
small shortfall in earnings from, or a change in, analysts' expectations
may cause an immediate and substantial decline in the Company's stock
price. Investors in the Company's Common Stock must be willing to bear the
risk of such fluctuations in earnings and stock price.

Potential Adverse Impact of Health Care Reform

Numerous governments have undertaken efforts to control growing health care
costs through legislation, regulation and voluntary agreements with medical
care providers and pharmaceutical companies. In the last several years,
several comprehensive health care reform proposals were introduced in the
U.S. Congress. The intent of the proposals was, generally, to expand health
care coverage for the uninsured and reduce the growth of total health care
expenditures. While none of the proposals were adopted, health care reform
may again be addressed by the U.S. Congress. Implementation of government
health care reform may adversely affect research and development
expenditures by pharmaceutical and biotechnology companies, resulting in a
decrease of the business opportunities available to the Company. Management
is unable to predict the likelihood of health care reform proposals being
enacted into law or the effect such law would have on the Company.

Many European governments have also reviewed or undertaken health care
reform. For example, German health care reform legislation implemented in
January 1993 contributed to an estimated 15% decline in German
pharmaceutical industry sales in calendar 1993 and led several clients to
cancel contracts with the Company. Subsequent to these events, in the third
quarter of fiscal 1993, the Company restructured its German operations and
incurred a restructuring charge of approximately $3.3 million. In addition,
in the third quarter of fiscal 1995, the Company's results of operations
were affected by a non-cash write-down due to the impairment of long-lived
assets of PAREXEL GmbH, the Company's German subsidiary, of approximately
$11.3 million. The Company cannot predict the impact that any pending or
future health care reform proposals may have on the Company's business in
Europe.

Dependence on Personnel; Ability to Attract and Retain Personnel

The Company relies on a number of key executives, including Josef H. von
Rickenbach, its President, Chief Executive Officer and Chairman, upon whom
the Company maintains key man life insurance. Although the Company has
entered into agreements containing non-competition restrictions with its
senior officers, the Company does not have employment agreements with
certain of these persons and the loss of the services of any of the
Company's key executives could have a material adverse effect on the
Company.

The Company's performance also depends on its ability to attract and retain
qualified professional, scientific and technical operating staff. The level
of competition among employers for skilled personnel, particularly those
with M.D., Ph.D. or equivalent degrees, is high. There can be no assurance
the Company will be able to continue to attract and retain qualified staff.

Potential Liability; Possible Insufficiency of Insurance

Clinical research services involve the testing of new drugs on consenting
human volunteers pursuant to a study protocol. Such testing involves a risk
of liability for personal injury or death to patients due to, among other
reasons, possible unforeseen adverse side effects or improper
administration of the new drug. Many of these patients are already
seriously ill and are at risk of further illness or death. The Company
could be materially and adversely affected if it were required to pay
damages or incur defense costs in connection with a claim that is outside
the scope of an indemnity or insurance coverage, or if the indemnity,
although applicable, is not performed in accordance with its terms or if
the Company's liability exceeds the amount of applicable insurance. In
addition, there can be no assurance that such insurance will continue to be
available on terms acceptable to the Company.

Adverse Effect of Exchange Rate Fluctuations

Approximately 33% of the Company's net revenue for fiscal 1997, 35% for
fiscal 1996 and 1995, and 30% for the three months ended September 30,
1997, was derived from the Company's operations outside of North America.
Since the revenue and expenses of the Company's foreign operations are
generally denominated in local currencies, exchange rate fluctuations
between local currencies and the United States dollar will subject the
Company to currency translation risk with respect to the results of its
foreign operations. To the extent the Company is unable to shift to its
clients the effects of currency fluctuations, these fluctuations could have
a material adverse effect on the Company's results of operations. The
Company does not currently hedge against the risk of exchange rate
fluctuations.

Anti-Takeover Provisions; Possible Issuance of Preferred Stock

The Company's Restated Articles of Organization and Restated By-Laws
contain provisions that may make it more difficult for a third party to
acquire, or may discourage a third party from acquiring, the Company. These
provisions could limit the price that certain investors might be willing to
pay in the future for shares of the Company's Common Stock. In addition,
shares of the Company's Preferred Stock may be issued in the future without
further stockholder approval and upon such terms and conditions, and having
such rights, privileges and preferences, as the Board of Directors may
determine. The rights of the holders of Common Stock will be subject to,
and may be adversely affected by, the rights of any holders of Preferred
Stock that may be issued in the future. The issuance of Preferred Stock,
while providing desirable flexibility in connection with possible
acquisitions and other corporate purposes, could adversely affect the
market price of the Common Stock and could have the effect of making it
more difficult for a third party to acquire, or discouraging a third party
from acquiring, a majority of the outstanding voting stock of the Company.
The Company has no present plans to issue any shares of Preferred Stock.

USE OF PROCEEDS
The Company will not receive any proceeds from the resale of the Shares of
Common Stock by the Selling Stockholders hereunder.  See "Selling
Stockholders" and "Plan of Distribution."
The principal purpose of this offering is to effect an orderly disposition
of the Selling Stockholders' Shares.

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

As described in Notes 2 and 16 to the supplemental consolidated financial
statements, the Company consummated a business combination with Kemper-
Masterson, Inc. in December 1997 which was accounted for as a pooling of
interests.  All financial data in this discussion and analysis is reported
as though the companies were combined for all periods.

OVERVIEW

The Company is a leading contract research organization ("CRO") providing a
broad range of knowledge-based product development and product launch
services on a contract basis to the worldwide pharmaceutical,
biotechnology, and medical device industries. The Company has developed
expertise in such disciplines as: clinical trials management,
biostatistical analysis and data management, medical marketing, clinical
pharmacology, regulatory and medical consulting, information technology,
industry training and publishing, and other drug development consulting
services. Founded in 1983, the Company has built its business through
internal expansion and acquisitions.

The Company's services contracts are generally fixed price with some
variable components and range in duration from a few months to several
years. A portion of the fee is typically required to be paid at the time
the contract is entered into and the balance in installments over the
duration of the contract, in some cases on a milestone-achievement basis.
Revenue from the contracts is generally recognized on a percentage-of-
completion basis as work is performed.

Most of the Company's contracts are terminable upon 60 to 90 days' notice
by the client. 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 undesired clinical results of
the product, the client's decision to forego a particular study,
insufficient patient enrollment or investigator recruitment, or production
problems resulting in shortages of the drug.

As is customary in the industry, the Company routinely subcontracts with
third party investigators in connection with clinical trials and with other
third party service providers for laboratory analysis and other specialized
services. These and other reimbursable costs are paid by the Company and
reimbursed by clients and, in accordance with industry practice, are
included in gross revenue. Reimbursed costs vary from contract to contract.
Accordingly, the Company views net revenue, which consists of gross revenue
less reimbursed costs, as its primary measure of revenue growth.

Direct costs consist of compensation and related fringe benefits for
project-related employees, other project-related costs not reimbursed, and
allocated facilities and information systems costs. Selling, general, and
administrative expenses consist of compensation and related fringe benefits
for selling and administrative employees, professional services, and
advertising costs, as well as allocated costs related to facilities and
information systems.

The following table presents, for the periods indicated, net revenue by
geographic region and the percentage of total net revenue represented by
each region.

</TABLE>

The Company's foreign subsidiaries generally enter into contracts
denominated in the local currency of the foreign subsidiary. Because
expenses of the foreign subsidiaries are generally paid in the local
currency, such foreign subsidiaries' local currency earnings are not
materially affected by fluctuations in exchange rates. However, changes in
the exchange rates between these local currencies and the U.S. dollar will
affect the translation of such subsidiaries' financial results into U.S.
dollars for the purposes of reporting the Company's supplemental
consolidated financial results. In cases where the Company contracts for a
multi-country clinical trial and a significant portion of the contract
expenses are in a currency other than the contract currency, the Company
seeks to contractually shift to its client the effect of fluctuations in
the relative values of the contract currency and the currency that the
expenses are incurred. To the extent the Company is unable to shift to its
clients the effects of currency fluctuations, these fluctuations could have
a material effect on the Company's results of operations. The Company does
not currently hedge against the risk of exchange rate fluctuations.

As the Company conducts operations on a global basis, the Company's
effective tax rate has depended, and will continue to depend, upon the
distribution of its revenue among geographic locations with varying tax
rates.

The Company's results of operations may be affected by changes in the tax
rates of the various jurisdictions. In particular, from period to period,
as the geographic mix of the Company's results of operations among various
tax jurisdictions changes, the Company's effective tax rate may vary
significantly.

RESULTS OF OPERATIONS

As an aid to understanding the Company's operating results, the following
table indicates the percentage relationships of income and expense items
included in the Supplemental Consolidated Statements of Operations for the
three years ended June 30, 1997, and the three months ended September 30,
1997, and 1996, and the percentage changes in those items for such periods:

THREE MONTHS ENDED SEPTEMBER 30, 1997,
COMPARED TO THREE MONTHS ENDED SEPTEMBER 30, 1996

Net revenue increased by $19.0 million, or 54.0%, from $35.2 million for
the three months ended September 30, 1996, to $54.3 million for the three
months ended September 30, 1997.  This net revenue growth was primarily
attributable to an increase in the volume and average contract value of
clinical research projects serviced by the Company.  For the three months
ended September 30, 1997, net revenue from North American and European
operations increased by $14.2 million and $4.2 million, respectively, over
the corresponding prior year period.  There can be no assurance that the
Company can sustain this rate of increase in net revenue from continuing
operations in future periods.  See "Risk Factors."

Direct costs increased by $12.1 million, or 50.0%, from $24.2 million for
the three months ended September 30, 1996, to $36.3 million for the three
months ended September 30, 1997.  This increase in direct costs was due to
the increase in the number of project-related personnel, hiring, facilities
and information system costs necessary to support the increased level of
operations.  Direct costs as a percentage of net revenue decreased from
68.7% for the three months ended September 30, 1996, to 66.9% for the three
months ended September 30, 1997, primarily due to improved performance of
the Company's North American operations.

Selling, general and administrative expenses increased by $3.7 million, or
50.4%, from $7.3 million for the three months ended September 30, 1996 to
$11.0 million for the three months ended September 30, 1997.  This increase
was primarily due to increased administrative personnel, hiring, and
facilities costs necessary to accommodate the Company's growth.  Selling,
general and administrative expenses as a percentage of net revenue
decreased slightly from 20.7% for the three months ended September 30,
1996, to 20.2% for the three months ended September 30, 1997.

Depreciation and amortization expense increased by $1.1 million, or 111.6%,
from $958,000 for the three months ended September 30, 1996 to $2.0 million
for the three months ended September 30, 1997.  The increase is primarily
due to increased capital spending on computer equipment and facilities to
support the increase in project-related personnel.

Income from operations for the three months ended September 30, 1997,
increased by $2.2 million, or 78.8%, from $2.8 million for the three months
ended September 30, 1996, to $5.0 million for the three months ended
September 30, 1997.

Interest income increased by $549,000 from $439,000 for the three months
ended September 30, 1996, to $988,000 for the three months ended September
30, 1997.  This increase resulted from higher average balances of cash,
cash equivalents and marketable securities due primarily to proceeds from
the Company's December 1996 public offering.

The Company's effective income tax rate was 35.0% for the three months
ended September 30, 1997, compared to 36.8% for the three months ended
September 30, 1996.  This decrease was due to changes in the mix of taxable
income from the different jurisdictions in which the Company operates and
the impact of tax-exempt interest income from securities held by the
Company.

FISCAL YEAR ENDED JUNE 30, 1997, COMPARED TO FISCAL YEAR ENDED JUNE 30,
1996

Net revenue increased $73.0 million, or 75.0%, from $97.4 million for
fiscal 1996 to $170.4 million for 1997.  This growth in revenue was
primarily attributable to an increase in the volume and average contract
value of clinical research projects serviced by the Company and to a lesser
extent, the Company's acquisitions since June 1996.  In fiscal 1997, net
revenue in North America and in Europe increased $50.1 million and $20.8
million, respectively, over the prior year.

Direct costs increased $49.5 million, or 74.8%, from $66.2 million for
fiscal 1996 to $115.7 million for 1997.  This increase in direct costs was
due to the increase in the number of project-related personnel, hiring,
facilities, and information system costs necessary to support the increased
level of operations.  As a percentage of net revenue, direct costs remained
essentially unchanged, decreasing slightly from 68.0% in fiscal 1996 to
67.9% in 1997.

Selling, general, and administrative expenses increased $13.4 million, or
61.0%, from $21.9 million for fiscal 1996 to $35.3 million for 1997.  This
increase was primarily due to increased costs associated with additional
administrative personnel, greater hiring and selling costs, and additional
facilities to accommodate the Company's growth.  As a percentage of net
revenue, selling, general, and administrative expenses decreased from 22.5%
in fiscal 1996 to 20.7% in 1997, primarily due to leveraging of
infrastructure over an expanding revenue base.

Depreciation and amortization expense increased $2.7 million, or 103.1%
from $2.6 million for fiscal 1996 to $5.4 million for 1997. This increase
was primarily due to increased capital spending on computer equipment and
facilities to support the increase in project-related personnel required to
support the increased level of operations.

Income from operations increased $7.4 million, or 112.1%, from $6.6 million
for fiscal 1996 to $14.1 million in 1997.  As a percentage of net revenue,
income from operations increased to 8.3% in fiscal 1997, compared to 6.8%
in 1996.

Interest income increased $2.2 million in fiscal 1997 as a result of higher
average balances of cash and investments.  This increase was due to
proceeds from the Company's public offering and cash generated from
operations.

The Company's effective income tax rate decreased from 39.7% in fiscal 1996
to 36.2% in fiscal 1997.  This decrease was attributable to changes in the
mix of taxable income from the different geographic jurisdictions that the
Company operated in fiscal 1997 compared to 1996.

FISCAL YEAR ENDED JUNE 30, 1996, COMPARED TO FISCAL YEAR ENDED JUNE 30,
1995

Net revenue increased $30.3 million, or 45.1%, from $67.1 million for
fiscal 1995 to $97.4 million for 1996.  This net revenue growth was
attributable to an increase in the number and average contract value of
clinical research projects serviced by the Company.

Direct costs increased $18.1 million, or 37.8%, from $48.1 million for
fiscal 1995 to $66.2 million for 1996.  This increase in direct costs was
due to the increase in the number of project-related personnel, facilities,
and information system costs necessary to support the increased level of
operations.  Direct costs as a percentage of net revenue decreased from
71.6% for 1995 to 68.0% for 1996, primarily due to improved workforce and
facility utilization.

Selling, general and administrative expenses increased $6.1 million, or
38.6%, from $15.8 million for fiscal 1995 to $21.9 million for 1996.  This
increase was primarily due to increased costs associated with additional
administrative personnel, greater hiring and selling costs, and additional
facilities to support the Company's growth and operation as a publicly held
company.  Selling, general and administrative expenses as a percentage of
net revenue decreased from 23.6% for fiscal 1995 to 22.5% for 1996,
primarily due to leveraging of infrastructure over an expanded revenue
base.

Depreciation and amortization expense increased $206,000, or 8.5%, from
$2.4 million for fiscal 1995 to $2.6 million for 1996.  The change resulted
from an increase in depreciation associated with increased capital
expenditures, offset by a decrease in depreciation and amortization due to
the write-down of impaired long-lived assets of the Company's German
operations.  See Note 3 to the Supplemental Consolidated Financial
Statements entitled, "Impairment of Long Lived Assets."  Depreciation and
amortization expense in fiscal 1995 includes approximately $588,000 related
to long-lived assets which were written-down and did not recur in 1996.

Income from operations for fiscal 1996 was $6.6 million, compared to a loss
from operations of $10.4 million for 1995.  Results for 1995 included an
$11.3 million noncash charge related to the write-down of impaired long-
lived assets of the Company's German operations.  Income from operations
for 1995, excluding the impact of the asset impairment charge, was
approximately $221,000.

Interest income increased by $1.1 million in fiscal 1996.  This increase
resulted from higher average balances of cash and investments due primarily
to proceeds from the Company's public offerings in November 1995 and March
1996.

The Company's effective income tax rate was 39.7% for fiscal 1996.  The
effective tax rate in fiscal 1995, excluding the effect of the $11.3
million noncash, nondeductible write-down due to the impairment of long-
lived assets, would have been 101.0%.  The effective income tax rate may
vary with changes in the mix of taxable income from the different
geographic jurisdictions in which the Company operates.

LIQUIDITY AND CAPITAL RESOURCES

Since its inception, the Company has financed its operations and growth,
including acquisition costs, with cash flow from operations and the
proceeds from the sale of equity securities.  Investing activities
primarily reflect capital expenditures for information systems
enhancements, leasehold improvements, and net purchases of marketable
securities.

The Company's clinical research and development contracts are generally
fixed price with some variable components, and range in duration from a few
months to several years.  The cash flows from contracts typically consists
of a down payment required to be paid at the time the contract is entered
into and the balance in installments over the contract's duration, in some
cases on a milestone-achievement basis.  Revenue from contracts is
recognized on a percentage-completion basis as the work is performed.
Accordingly, cash receipts do not necessarily correspond to costs incurred
and revenue recognized on contracts.

The Company's cash flow is influenced by the changes in levels of billed
and unbilled accounts receivable, net of amounts advance billed
representing unearned revenue.  As a result, the number of days outstanding
in accounts receivable, net of advance billings, and the related dollar
values of these accounts can vary due to the achievement of contractual
milestones and the timing and size of cash receipts.  The number of days
revenue outstanding, net of advance billings, was 48 days at June 30, 1996,
45 days at June 30, 1997, and 55 days at September 30, 1997.  The increase
in days revenue outstanding from June 30, 1997, to September 30, 1997, was
primarily due to the timing of the achievement of project milestones and
related billings.  Accounts receivable, net of the allowance for doubtful
accounts, increased from $42.1 million at June 30, 1996, to $66.1 million
at June 30, 1997, and $70.3 million at September 30, 1997; while advance
billings increased from $20.7 million at June 30, 1996, to $33.4 million at
June 30, 1997, and decreased to $29.7 million at September 30, 1997.

During the three months ended September 30, 1997, unrestricted cash and
cash equivalents increased by $19.5 million as a result of $22.7 million
and $1.6 million in cash provided by investing and financing activities,
respectively, partially offset by $4.3 million in cash used by operating
activities and a $411,000 unfavorable effect of exchange rate changes.  Net
cash used by operating activities resulted from increases in accounts
receivable of $5.2 million and decreases in advance billings, accounts
payable, and other current liabilities of $3.0 million, $1.3 million, and
$891,000, respectively, partially offset by net income, excluding noncash
expenses, of $5.9 million.  Cash provided by investing activities consisted
primarily of net proceeds from sales of marketable securities of $29.3
million, partially offset by capital expenditures of $6.6 million related
to facility expansion and investments in information technology.  Financing
activities consisted primarily of net proceeds from the exercise of stock
options of $1.4 million.

Unrestricted cash and cash equivalents increased by $12.1 million during
fiscal 1997 as a result of $15.6 million of cash provided by operations and
$56.6 million provided by financing activities, offset by $59.1 million of
cash used for investing activities and a $968,000 unfavorable effect of
exchange rate changes.  Net cash provided by operating activities resulted
primarily from net income, excluding noncash expenses, of $16.4 million and
increases in advance billings and other current liabilities of $12.4
million and $12.8 million, respectively.  Cash used by operating activities
included increases in accounts receivable and other current assets of $21.6
million and $3.0 million, respectively.  Financing activities consisted
primarily of net proceeds of approximately $57.2 million from the Company's
December 1996 follow-on public offering of 2,516,300 shares of common stock
net of repayments of long-term debt of $3.5 million.  Debt repayments
included $2.3 million to retire third party debt assumed during the August
1996 acquisition of State and Federal Associates, Inc.  Investing
activities consisted of net purchases of marketable securities of $37.5
million and capital expenditures.

The Company has invested approximately $22.4 million in fiscal 1997 for
capital expenditures related to facility expansion and investments in
information systems technology and expects to invest approximately $25.0
million in the next twelve months.

The Company has domestic and foreign lines of credit with banks totaling
approximately $14.4 million, and a capital lease line of credit with a U.S.
bank for $2.4 million. At September 30, 1997, the Company had approximately
$15.1 million in available credit under these arrangements.

The Company's primary short-term and long-term cash needs are for the
payment of the salaries and fringe benefits, hiring and recruiting
expenses, business development costs, capital expenditures and facility-
related expenses.  The Company believes that its existing capital resources
together with cash flows from operations and borrowing capacity under
existing lines of credit will be sufficient to meet its foreseeable cash
needs.  In the future, the Company will consider acquiring businesses to
enhance its service offerings, therapeutic base, and global presence.  Any
such acquisitions may require additional external financing, and the
Company may from time to time seek to obtain funds from public or private
issuances of equity or debt securities.  There can be no assurance that
such financing will be available on terms acceptable to the Company.

The statements included in Management's Discussion and Analysis of
Financial Condition and Results of Operations include forward-looking
statements which involve risks and uncertainties.  The Company's actual
experience may differ materially from that discussed above.  Factors that
might cause such a difference include, but are not limited to, the loss or
delay of large contracts, the Company's dependence on certain industries
and clients and government regulation of such industries and clients,
competition or consolidation within the industry, as well as those
discussed in "Risk Factors" herein and in the Company's Quarterly Report on
Form 10-Q for the quarter ended September 30, 1997.

INFLATION

The Company believes the effects of inflation generally do not have a
material adverse impact on its operations or financial condition.

YEAR 2000

The Company recognizes that it must ensure that its services and operations
will not be adversely affected by Year 2000 software failures (the "Year
2000 issue") which can arise in time-sensitive software applications with
two-year digits to define the applicable year.  In such applications, a
date using "00" as the year may be recognized as the year 1900 rather than
the year 2000.  The Company is in the process of replacing many of its
business and computer operating systems with software which, when upgraded,
are Year 2000 compatible.  The Company is planning to complete all
necessary Year 2000 upgrades of its major systems and is currently
identifying and developing conversion strategies for its remaining systems
that may be impacted by the Year 2000 issue.

RECENTLY ISSUED ACCOUNTING STANDARDS

In February 1997, the Financial Accounting Standards Board (FASB) issued
Statement of Financial Accounting Standards (SFAS) No. 128, "Earnings per
Share." This statement establishes and simplifies standards for computing
and presenting earnings per share. SFAS No. 128 will be effective for the
Company's second quarter of fiscal 1998 and requires the restatement of all
previously reported earnings per share data presented. Early adoption of
this Statement is not permitted. SFAS No. 128 replaces primary and fully
diluted earnings per share with basic and diluted earnings per share. The
Company expects that basic and diluted earnings per share amounts will not
be materially different from the Company's primary and fully diluted
earnings per share amounts.

In June 1997, the FASB issued SFAS No. 130, "Reporting Comprehensive
Income," and SFAS No. 131, "Disclosures about Segments of an Enterprise and
Related Information." SFAS No. 130 establishes standards for reporting and
display of comprehensive income and its components in the supplemental
consolidated financial statements. SFAS No. 131 establishes standards for
reporting information on operating segments in interim and annual financial
statements. Both statements are effective for the Company for fiscal 1999.

In November 1997, the Emerging Issues Task Force (EITF) reached a consensus
on issue 97-13, "Accounting for Costs Incurred in Connection with a
Consulting Contract or an Internal Project that Combines Business Process
Reengineering and Information Technology Transformation"  (EITF 97-13) that
the costs of business process reengineering activities, whether done
internally or by third parties, is to be expensed as incurred.  The
consensus also applies to the costs of business process reengineering
activities conducted in conjunction with a project to acquire, develop, or
implement internal-use software.  The transition provisions of EITF 97-13
require unamortized previously capitalized costs for business process
reengineering activities to be written off in the Company's fiscal quarter
ending December 31, 1997 and reported as a cumulative effect of a change in
accounting principle.  The Company is in the process of assessing the
impact of EITF 97-13 and does not expect that it will have a material
affect on its results of operations for the quarter ending December 31,
1997.

(1)  Assuming all of the Shares owned by each Selling Stockholder and
  offered pursuant to this Prospectus are sold.
(2)  As of January 14, 1998, there were 20,804,987 shares of Common Stock
  outstanding.

None of the Selling Stockholders has had any material relationship with the

described below.

Each of Clarence A. Kemper, P. Michael Masterson, Mark A. Lester, Ronald F.
Tetzlaff, Alan R. Parenteau, Jon Voss, Warren Handren and David Hyde (the
"KMI Stockholders") acquired his Shares in connection with the merger of
KMI Acquisition Corporation, a Massachusetts corporation and wholly-owned
subsidiary of the Company, with and into Kemper-Masterson, Inc., a Delaware
corporation ("KMI") (the "KMI Merger"), pursuant to an Agreement and Plan
of Reorganization and Merger dated October 22, 1997 by and among KMI, KMI
Acquisition Corporation, the Company and the KMI Stockholders (the "Merger
Agreement"). Pursuant to the terms of a Registration Rights Agreement dated
December 1, 1997 by and among the KMI Stockholders and the Company, 290,909
of the 581,817 shares of Common Stock issued to the KMI Stockholders in
connection with the KMI Merger are being offered hereby.  The Company has
agreed to register the remaining 290,908 shares of Common Stock issued to
the KMI Stockholders approximately 180 days after the date of this
Prospectus.  Such rights are more fully described in the Registration
Rights Agreement filed as Exhibit 4.3 herewith.

An aggregate of 55,706 shares of Common Stock issued to the KMI
Stockholders are being held in escrow pursuant to the Merger Agreement.  Of
the 55,706 shares being held in escrow, an aggregate of 25,297 shares are
being held back until the earlier of (i) December 1, 1998 or (ii) the
delivery of an audit report relating to the Company's financial statements
for the fiscal year ended June 30, 1998.  These shares will be used to
satisfy any indemnification claims which may be brought by the Company
based upon a breach of the representations or warranties of KMI or the KMI
Stockholders as set forth in the Merger Agreement.  An aggregate of 30,409
shares held in escrow will be used if necessary to satisfy certain tax
withholding obligations of the KMI Stockholders.  These shares will be
distributed to the KMI Stockholders, to the extent not used to satisfy such
tax withholding obligations, within approximately 25 days after the date
the shares are no longer subject to restriction on transfer pursuant to the
pooling of interests accounting rules.  Each of the KMI Stockholders has
sole authority to hold or dispose of, and to vote all securities held by
him, including those shares held in escrow by the Company but issued in the
name of the KMI Stockholder.  Each of the KMI Stockholders is presently
employed by KMI in its capacity as a wholly-owned subsidiary of the
Company, including Mr. Masterson, who serves as KMI's President.   The KMI
Merger was accounted for as a pooling of interests for financial accounting
purposes.

Perceptive Systems, Inc., a Colorado corporation doing business as Hayden
Image Processing Group ("Hayden") acquired its Shares in connection with
the acquisition by the Company of substantially all of the assets of Hayden
pursuant to an Asset Purchase Agreement dated September 26, 1997 by and
among the Company, Hayden and Howard W. Foster, the sole stockholder of
Hayden (the "Asset Purchase Agreement").  In connection with the
anticipated dissolution of Hayden, the 5,035 shares of Common Stock issued
to Hayden were subsequently transferred to Howard W. Foster, the sole
stockholder of Hayden.  Pursuant to the terms of a Registration Rights
Agreement dated September 26, 1997 by and between Hayden and the Company,
all of the 5,035 shares of Common Stock issued upon the closing of the
Hayden Acquisition are being offered hereby. In addition, the Company has
granted certain "piggyback" rights with respect to the Contingent Shares
which would allow the registration of the Contingent Shares on future
registration statements filed by the Company.  Such rights are more fully
described in the Registration Rights Agreement filed as Exhibit 4.5
herewith.  Howard Foster is currently the Director of Medical Imaging
Research and Development at the Company.
Each of the Selling Stockholders represented to the Company, in connection
with the completion of the KMI Merger and the Hayden Acquisition, that he
or it was acquiring the Shares from the Company without any present
intention of effecting a distribution of those Shares.  In recognition of
the fact that the Selling Stockholders may want to be able to sell their
shares when they consider appropriate, the Company agreed to file with the
Commission a Registration Statement on Form S-3 (the "Registration
Statement") (of which this Prospectus is a part) to permit the public sale
of the Shares by the Selling Stockholders from time to time and to use its
commercially reasonable efforts to keep the Registration Statement
effective until the earlier of the sale of all of the Shares pursuant to
this Registration Statement or October 22, 1998.  The Company will prepare
and file such amendments and supplements to the Registration Statement as
may be necessary to keep it effective until the earlier of the sale of all
Shares pursuant to the registration statement or until October 22, 1998.

Pursuant to the Registration Rights Agreements by and between the Company
and each of the Selling Stockholders (collectively, the "Registration
Rights Agreements"), the Company has agreed to bear all expenses in
connection with the registration and resale of the Shares (other than
underwriting discounts and selling commissions and the fees and expenses of
counsel and other advisors to the Selling Stockholders).  See "Plan of
Distribution."  The Registration Rights Agreements provide that the Company
will indemnify the Selling Stockholders for any losses incurred by them in
connection with actions arising from any untrue statement of a material
fact in the Registration Statement or any omission of a material fact
required to be stated therein, unless such statement or omission was made
in reliance upon written information furnished to the Company by the
Selling Stockholder.  Similarly, the Registration Rights Agreements provide
that each Selling Stockholder will indemnify the Company and its officers
and directors for any losses incurred by them in connection with any action
arising from any untrue statement of material fact in the Registration
Statement or any omission of a material fact required to be stated therein,
if such statement or omission was made in reliance on written information
furnished to the Company by such Selling Stockholder.

Insofar as indemnification for liabilities arising under the Securities Act
of 1933 may be permitted to directors, officers or persons controlling the
registrant pursuant to the foregoing provisions, the Company has been
informed that in the opinion of the Securities and Exchange Commission such
indemnification is against public policy as expressed in the Act and is
therefore unenforceable.

DESCRIPTION OF CAPITAL STOCK

     The current authorized capital stock of the Company is 50,000,000
shares of Common Stock, par value $.01 per share, and 5,000,000 shares of
Preferred Stock, par value $.01 per share.

Common Stock

     As of January 14, 1998, there were 20,804,987 shares of Common Stock
outstanding and held of record by 108 stockholders.

     Holders of Common Stock are entitled to one vote for each share held
on all matters submitted to a vote of stockholders. Holders of Common Stock
do not have cumulative voting rights. Accordingly, holders of a majority of
the shares of Common Stock entitled to vote in any election of directors
may elect all of the directors standing for election. Holders of Common
Stock are entitled to receive ratably such dividends, if any, as may be
declared by the Board of Directors out of funds legally available therefor,
subject to any preferential dividend rights of any outstanding Preferred
Stock. Upon the liquidation, dissolution or winding up of the Company, the
holders of Common Stock are entitled to receive ratably the net assets of
the Company available after the payment of all debts and other liabilities
and subject to the prior rights of any outstanding Preferred Stock. Holders
of the Common Stock have no preemptive, subscription, redemption or
conversion rights. The outstanding shares of Common Stock are, and the
shares offered by the Company in this offering will be, when issued and
paid for, fully paid and nonassessable. The rights, preferences and
privileges of holders of Common Stock are subject to, and may be adversely
affected by, the rights of the holders of shares of any series of Preferred
Stock which the Company may designate and issue in the future.

Preferred Stock

     The Board of Directors is authorized, subject to certain limitations
prescribed by law, without further stockholder approval, to issue from time
to time up to an aggregate of 5,000,000 shares of Preferred Stock in one or
more series and to fix or alter the designations, preferences, rights and
any qualifications, limitations or restrictions of the shares of each such
series thereof, including the dividend rights, dividend rates, conversion
rights, voting rights, terms of redemption (including sinking fund
provisions), redemption price or prices, liquidation preferences and the
number of shares constituting any series or designations of such series.
The issuance of Preferred Stock may have the effect of delaying, deferring
or preventing a change of control of the Company.  There are no shares of
Preferred Stock outstanding.  The Company has no present plans to issue any
shares of Preferred Stock.

Massachusetts Law and Certain Provisions of the Company's Restated Articles
of Organization and By-Laws

     The Company believes that it has more than 200 beneficial
stockholders, thus making it subject to Chapter 110F of the Massachusetts
General Laws, an anti-takeover law. In general, this statute prohibits a
publicly held Massachusetts corporation from engaging in a "business
combination" with an "interested stockholder" for a period of three years
after the date of the transaction in which the person becomes an interested
stockholder, unless (i) the interested stockholder obtains the approval of
the board of directors prior to becoming an interested stockholder, (ii)
the interested stockholder acquires 90% of the outstanding voting stock of
the corporation (excluding shares held by certain affiliates of the
corporation) at the time it becomes an interested stockholder, or (iii) the
business combination is approved by both the board of directors and the
holders of two-thirds of the outstanding voting stock of the corporation
(excluding shares held by the interested stockholder). An "interested
stockholder" is a person who, together with its affiliates and associates,
owns (or at any time within the prior three years did own) 5% or more of
the outstanding voting stock of the corporation. A "business combination"
includes a merger, a stock or asset sale, and certain other transactions
resulting in a financial benefit to the interested stockholder. .  There
are no shares of Preferred Stock outstanding. The Company may at any time
elect not to be governed by Chapter 110F by vote of a majority of its
stockholders, but such an amendment would not be effective for twelve
months and would not apply to a business combination with any person who
became an interested stockholder prior to the adoption of the amendment.

     The Massachusetts Business Corporation Law generally requires that
publicly-held Massachusetts corporations have a classified board of
directors consisting of three classes as nearly equal in size as possible,
unless those corporations elect to opt out of the statute's coverage. By
vote of the Board of Directors, the Company has elected to opt out of the
classified board provisions of this statute and has adopted separate
classified Board provisions in its Restated Articles of Organization.

     The Company's By-Laws include a provision that excludes the Company
from the applicability of Massachusetts General Laws Chapter 110D, entitled
"Regulation of Control Share Acquisitions." In general, this statute
provides that any stockholder of a corporation subject to this statute who
acquires 20% or more of the outstanding voting stock of a corporation may
not vote such stock unless the stockholders of the corporation so
authorize. The Board of Directors may amend the Company's By-Laws at any
time to subject the Company to this statute prospectively.

     The Company's By-Laws require that nominations for the Board of
Directors made by a stockholder comply with certain notice procedures. A
notice by a stockholder of a planned nomination must be given not less than
60 and not more than 90 days prior to a scheduled meeting, provided that if
less than 70 days' notice is given of the date of the meeting, a
stockholder will have ten days within which to give such notice. The
stockholder's notice of nomination must include particular information
about the stockholder, the nominee and any beneficial owner on whose behalf
the nomination is made. The Company may require any proposed nominee to
provide such additional information as is reasonably required to determine
the eligibility of the proposed nominee.

     The By-Laws also require that a stockholder seeking to have any
business conducted at a meeting of stockholders give notice to the Company
not less than 60 and not more than 90 days prior to the scheduled meeting,
provided that if less than 70 days' notice is given of the date of the
meeting, a stockholder will have ten days within which to give such notice.
The notice from the stockholder must describe the proposed business to be
brought before the meeting and include information about the stockholder
making the proposal, any beneficial owner on whose behalf the proposal is
made, and any other stockholder known to be supporting the proposal. The By-
Laws require the Company to call a special stockholders' meeting at the
request of stockholders holding at least 33 1/3% of the voting power of the
Company.

     The Company's Restated Articles of Organization include provisions
eliminating the personal liability of the Company's directors for monetary
damages resulting from breaches of their fiduciary duty to the extent
permitted by the Massachusetts Business Corporation Law. Additionally, the
Company's Restated Articles of Organization provide that the Company shall
indemnify each person who is or was a director or officer of the Company,
and each person who is or was serving or has agreed to serve at the request
of the Company as a director or officer of, or in a similar capacity with,
another organization or in any capacity with respect to any employee
benefit plan of the Company, against all liabilities, costs and expenses
reasonably incurred by any such persons in connection with the defense or
disposition of or otherwise in connection with or resulting from any
action, suit or other proceeding in which they may be involved by reason of
being or having been such a director or officer, or by reason of any action
taken or not taken in such capacity, except with respect to any matter as
to which such person shall have been finally adjudicated by a court of
competent jurisdiction not to have acted in good faith in the reasonable
belief that his or her action was in the best interests of the Company or,
to the extent such matter relates to service with respect to an employee
benefit plan, in the best interests of the participants or beneficiaries of
such employee benefit plan.

     The Restated Articles of Organization provide that certain
transactions, such as the sale, lease or exchange of all or substantially
all of the Company's property and assets and the merger or consolidation of
the Company into or with any other corporation, may be authorized by the
approval of the holders of a majority of the shares of each class of stock
entitled to vote thereon, rather than by two-thirds as otherwise provided
by statute, provided that the transactions have been authorized by a
majority of the members of the Board of Directors and the requirements of
any other applicable provisions of the Restated Articles of Organization
have been met.

     Certain of the provisions of the Restated Articles of Organization and
By-Laws discussed above would discourage or make more difficult a proxy
contest or the assumption of control by a holder of a substantial block of
the Company's stock. Such provisions could also have the effect of
discouraging a third party from making a tender offer or otherwise
attempting to obtain control of the Company, even though such an attempt
might be beneficial to the Company and its stockholders. In addition, since
the Restated Articles of Organization and By-Laws are designed to
discourage accumulations of large blocks of the Company's stock by
purchasers whose objective is to have stock repurchased by the Company at a
premium, such provisions could tend to reduce the temporary fluctuations in
the market price of the Company's stock which are caused by such
accumulations. Accordingly, stockholders could be deprived of certain
opportunities to sell their stock at a temporarily higher market price.

PLAN OF DISTRIBUTION

     The Shares offered hereby may be sold from time to time by the Selling
Stockholders for their own accounts.  The Company will receive none of the
proceeds from this offering.  The Selling Stockholders will pay or assume
brokerage commissions or other charges and expenses incurred in the resale
of the Shares.

     Resales of the Shares by the Selling Stockholders are not subject to
any underwriting agreement.  The Shares covered by this Prospectus may be
sold by the Selling Stockholders or by pledgees, donees, transferees or
other successors in interest.  The Shares offered by each Selling
Stockholder may be sold from time to time at market prices prevailing at
the time of sale, at prices relating to such prevailing market prices or at
negotiated prices.  Such sales may be effected in the over-the-counter
market, on the Nasdaq National Market, or on any exchange on which the
Shares may then be listed.  The Shares may be sold by one or more of the
following:  (a) one or more block trades in which a broker or dealer so
engaged will attempt to sell all or a portion of the Shares held by the
Selling Stockholders as agent but may position and resell a portion of the
block as principal to facilitate the transaction; (b) purchases by a broker
or dealer as principal and resale by such broker or dealer for its account
pursuant to this Prospectus; (c) ordinary brokerage transactions and
transactions in which the broker solicits purchasers; (d) in negotiated
transactions, and (e) through other means.  The Selling Stockholders may
effect such transactions by selling Shares through customary brokerage
channels, either through broker-dealers acting as agents or brokers, or
through broker-dealers acting as principals, who may then resell the
Shares, or at private sales or otherwise, at market prices prevailing at
the time of sale, at prices related to such prevailing market prices or at
negotiated prices.  The Selling Stockholders may effect such transactions
by selling Shares to or through broker-dealers, and such broker-dealers may
receive compensation in the form of underwriting discounts, concessions,
commissions, or fees from the Selling Stockholders and/or purchasers of the
Shares for whom such broker-dealers may act as agent or to whom they sell
as principal, or both (which compensation to a particular broker-dealer
might be in excess of customary commissions).  Any broker-dealers that
participate with the Selling Stockholders in the distribution of the Shares
may be deemed to be underwriters and any commissions received by them and
any profit on the resale of the Shares positioned by them might be deemed
to be underwriting compensation, within the meaning of the Securities Act,
in connection with such sales.

     The Company intends to maintain the effectiveness of this Prospectus
until October 22, 1998 or such period as is required to satisfy the
Company's obligations under the Registration Rights Agreements by and among
the Selling Stockholders and the Company; provided, however, that the
rights of the Selling Stockholders to resell the Shares pursuant to this
Registration Statement may be suspended by the Company under certain
circumstances, as set forth in the Registration Rights Agreements.

     The Company will inform the Selling Stockholders that the
antimanipulation rules under the Securities Exchange Act of 1934
(Regulation M - Rule 102) may apply to sales in the market and will furnish
the Selling Stockholders upon request with a copy of these Rules.  The
Company will also inform the Selling Stockholders of the need for delivery
of copies of this Prospectus.

     Any Shares covered by the Prospectus that qualify for resale pursuant
to Rule 144 under the Securities Act may be sold under Rule 144 rather than
pursuant to this Prospectus.

     The Common Stock is quoted on the Nasdaq National Market under the
symbol "PRXL."

LEGAL MATTERS

Certain legal matters with respect to the issuance of the Shares are being
passed upon for the Company and the Selling Stockholders by Testa, Hurwitz
& Thibeault, LLP, Boston, Massachusetts.

EXPERTS

The supplemental consolidated financial statements of the Company as of
June 30, 1997 and 1996 and for each of the three years in the period ended
June 30, 1997 included in this Prospectus and the Company's consolidated
financial statements as of June 30, 1997 and 1996 and for each of the three
years in the period ended June 30 1997 incorporated in this Prospectus by
reference to the Company's 1997 Annual Report on Form 10-K have been so
included and incorporated in reliance on the reports of Price Waterhouse
LLP, independent accountants, given on the authority of said firm as
experts in auditing and accounting.

Supplemental Consolidated Financial Statements

The following supplemental consolidated financial statements give
effect to the business combination between the Company and Kemper-
Masterson, Inc. ("KMI") consummated in December 1997 and accounted for
as a pooling of interests.  These supplemental financial statements
will become the restated historical financial statements of the
Company upon publication of the combined results of the companies
covering a period subsequent to the combination.  The supplemental
financial statements assume that the business combination occurred at
the earliest period presented.  Due to the differing year ends of the
Company and KMI, financial information for dissimilar fiscal years has
been combined in the supplemental consolidated financial statements
for the Company's fiscal year 1996 and 1995.  KMI's results of
operations for its fiscal years ended December 31, 1996 and 1995 were
combined with the Company's results of operations for the fiscal years
ended June 30, 1996 and 1995, respectively.  Balance sheet information
as of June 30, 1996 includes the financial position of KMI as of
December 31, 1996 and the Company as of June 30, 1996.  Accordingly,
KMI's results of operations for the six months ended December 31, 1996
(including revenue, operating income, and net income of $5.0 million,
$167,000, and $117,000, respectively) were duplicated in the combined
statements of operations for fiscal 1997 and 1996.  Therefore, KMI's
net income for one of the six month periods ended December 31, 1996,
was eliminated from stockholders' equity.
  
Supplemental consolidated earnings per share is based on the combined
weighted average number of shares of common stock of the Company, and
common stock issued by the Company to the former shareholders of KMI.
The supplemental consolidated balance sheets reflect the issuance of
shares of common stock of the Company in exchange for all of the
outstanding shares of KMI.

Report of Independent Accountants

To the Board of Directors and
Stockholders of PAREXEL International Corporation:

In our opinion, the accompanying supplemental consolidated balance
sheets and the related supplemental consolidated statements of
operations, of stockholders' equity and of cash flows present fairly,
in all material respects, the financial position of PAREXEL
International Corporation and its subsidiaries at June 30, 1997 and
1996, and the results of their operations and their cash flows for
each of the three years in the period ended June 30, 1997, in
conformity with generally accepted accounting principles.  These
financial statements are the responsibility of the Company's
management; our responsibility is to express an opinion on these
financial statements based on our audits.  We conducted our audits of
these statements in accordance with generally accepted auditing
standards which require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free
of material misstatement.  An audit includes examining, on a test
basis, evidence supporting the amounts and disclosures in the
financial statements, assessing the accounting principles used and
significant estimates made by management, and evaluating the overall
financial statement presentation.  We believe that our audits provide
a reasonable basis for the opinion expressed above.

As described in Note 16, on December 1, 1997, the Company merged with
Kemper-Masterson, Inc. in a transaction accounted for as a pooling of
interests.  The accompanying supplemental consolidated financial
statements give retroactive effect to the merger of the Company with
Kemper-Masterson, Inc.

The accompanying supplemental consolidated financial statements have
been prepared to give retroactive effect to the acquisition of Kemper-
Masterson, Inc. (KMI) by the Company accounted for as a pooling of
interests which occurred in December 1997 (Note 16).  Generally
accepted accounting principles prohibit giving effect to a consummated
business combination accounted for as a pooling of interests in
financial statements that do not include the date of consummation;
accordingly, these financial statements are supplemental information.
The accompanying supplemental consolidated financial statements do not
extend through the date of consummation; however, they will become the
historical consolidated financial statements of the Company after
financial statements covering the date of consummation of the business
combination are issued.

Principles of Consolidation

The supplemental consolidated financial statements include the
accounts of PAREXEL International Corporation and its wholly-owned
domestic and foreign subsidiaries. In fiscal year 1997, the Company's
French subsidiary changed its fiscal year end to June 30, which
resulted in a 13-month year. The additional month is included in the
fiscal year 1997 results of operations and does not materially affect
the Company's supplemental consolidated financial statements. For
fiscal year 1997, the Company's German subsidiary operated on a fiscal
year that ended May 31. For fiscal years 1996 and 1995, the Company's
German and French subsidiaries operated on a fiscal year that ended
May 31. All significant intercompany accounts and transactions have
been eliminated.

Accounting Estimates

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

Interim Financial Data (Unaudited)

The interim financial data included in the accompanying supplemental
consolidated financial statements and notes thereto, is unaudited;
however, in the opinion of the Company, the interim financial data
include all adjustments, consisting only of normal recurring
adjustments necessary for a fair presentation of the results for the
interim periods.  The interim financial data are not necessarily
indicative of the results of operations for a full fiscal year.

Revenue

Fixed price contract revenue is recognized using the percentage-of-
completion method based on the ratio that costs incurred to date bear
to estimated total costs at completion. Revenue from other contracts
is recognized as services are provided. Revenue related to contract
modifications is recognized when realization is assured and the
amounts are reasonably determinable. Adjustments to contract cost
estimates are made in the periods in which the facts that require the
revisions become known. When the revised estimate indicates a loss,
such loss is provided in the current period in its entirety. "Unbilled
accounts receivable" represents revenue recognized in excess of
amounts billed. "Advance billings" represents amounts billed in excess
of revenue recognized.

Investigator Fees

Investigator fees are accrued as investigator services are rendered.
The timing of payments to investigators is determined by reference to
predetermined contractual arrangements, which may differ from the
accrual of the expense. Payments to investigators in excess of amounts
accrued are classified as prepaid expenses included in other current
assets, and accrued expenses in excess of amounts paid are classified
as other current liabilities.

Cash, Cash Equivalents, Marketable Securities, and Financial
Instruments

The Company considers all highly liquid debt instruments purchased
with original maturities of three months or less to be cash
equivalents. Marketable securities include securities purchased with
original maturities of greater than three months. Cash equivalents and
marketable securities are classified as "available for sale" and are
carried at fair market value. Any unrealized gains or losses are
recorded as part of stockholders' equity. Restricted cash consists of
advances and deposits from customers subject to certain restrictions.

The Company occasionally purchases securities with seven-day put
options that allow the Company to sell the underlying securities in
seven days at par value. The Company uses these derivative financial
instruments on a limited basis to shorten contractual maturity dates,
thereby managing interest rate risk. Approximately $2.7 million of
securities were subject to seven-day put options at June 30, 1997, and
$1.0 million at June 30, 1996. The Company does not hold derivative
instruments for trading purposes.

Concentration of Credit Risk

Financial instruments which potentially expose the Company to
concentrations of credit risk include trade accounts receivable.
However, such risk is limited due to the large number of clients and
their international dispersion. In addition, the Company maintains
reserves for potential credit losses and such losses, in the
aggregate, have not exceeded management expectations. One customer
accounted for 11% of the Company's supplemental consolidated net
revenue for the year ended June 30, 1997. No single customer accounted
for more than 10% of the Company's supplemental consolidated net
revenue for the years ended June 30, 1996 and 1995.

Property and Equipment

Property and equipment is stated at cost. Depreciation is provided on
the straight-line method over the estimated useful lives of the assets
ranging from three to eight years. Leasehold improvements are
amortized over the lesser of the estimated useful lives of the
improvements or the remaining lease term. Repair and maintenance costs
are charged to expense as incurred.

Intangible Assets

Intangible assets consist principally of goodwill, customer lists,
covenants not to compete, and other intangible assets attributable to
businesses acquired. Goodwill represents the excess of the cost of
businesses acquired over the fair value of the related net assets at
the date of acquisition. Intangible assets are amortized using the
straight-line method over their expected useful lives. Goodwill and
other intangibles are currently being amortized over five to ten
years.

Impairment of Long-Lived Assets

The Company periodically assesses the recoverability of the carrying
amount of long-lived assets, including intangible assets. A loss is
recognized when expected future cash flows (undiscounted and without
interest) are less than the carrying amount of the asset. The amount
of the impairment loss is determined as the difference by which the
carrying amount of the asset exceeds the fair value of the asset.

Income Taxes

The Company accounts for income taxes in accordance with Statement of
Financial Accounting Standards No. 109. Deferred tax assets and
liabilities are recognized for the expected future tax consequences,
utilizing current tax rates, of temporary differences between the
carrying amounts and the tax bases of assets and liabilities. Deferred
tax assets are recognized, net of any valuation allowance, for the
estimated future tax effects of deductible temporary differences and
tax operating loss and credit carryforwards. Deferred income tax
expense represents the change in the net deferred tax asset and
liability balances.

Foreign Currency

Assets and liabilities of the Company's international operations are
translated into U.S. dollars at exchange rates in effect at the
balance sheet date. Income and expense items are translated at average
exchange rates prevailing during the year. Translation adjustments are
accumulated in a separate component of stockholders' equity. Realized
gains and losses recorded in the statements of operations were not
material for each period presented.

Net Income (Loss) Per Share

Net income (loss) per share is calculated based on the weighted
average number of common shares and common equivalent shares assumed
outstanding during the period. Pursuant to Securities and Exchange
Commission Staff Accounting Bulletin No. 83, certain common and common
equivalent shares issued by the Company during the twelve months
immediately preceding the initial filing of the registration statement
relating to the Company's initial public offering have been included
in the calculation of weighted average shares, using the treasury
stock method and the initial public offering price, as if these shares
were outstanding for all periods prior to the initial public offering.

Stock-Based Compensation

In October 1995, the Financial Accounting Standards Board (FASB)
issued Statement of Financial Accounting Standards (SFAS) No. 123,
"Accounting for Stock-Based Compensation." As permitted by SFAS No.
123, the Company has elected to continue to follow the accounting
provisions of Accounting Principles Board Opinion (APBO) No. 25,
"Accounting for Stock Issued to Employees," and furnish pro forma
disclosures.

Recently Issued Accounting Standards

In February 1997, the FASB issued SFAS No. 128, "Earnings per Share."
This statement replaces primary and fully diluted earnings per share
with basic and diluted earnings per share. SFAS No. 128 will be
effective for the Company's second quarter of fiscal 1998 and requires
the restatement of all previously reported earnings per share data
presented. Early adoption of this Statement is not permitted. The
Company expects that basic and diluted earnings per share amounts will
not be materially different from the Company's primary and fully
diluted earnings per share amounts.

In June 1997, the FASB issued SFAS No. 130, "Reporting Comprehensive
Income," and SFAS No. 131, "Disclosures about Segments of an
Enterprise and Related Information." SFAS No. 130 establishes
standards for reporting and display of comprehensive income and its
components in the supplemental consolidated financial statements. SFAS
No. 131 establishes standards for reporting information on operating
segments in interim and annual financial statements. Both statements
are effective for the Company for fiscal 1999.

NOTE 3.  IMPAIRMENT OF LONG-LIVED ASSETS

In the third quarter of fiscal 1995, PAREXEL GmbH's operations
suffered a decline in net revenue resulting in a net loss for the
period. Also during the third quarter, drug development regulations in
Germany and Europe were modified and further changes were being
contemplated, all of which were expected to have a detrimental impact
on PAREXEL GmbH's operations. Considering the cumulative impact of the
above-described factors, management assessed the realizability of the
long-lived assets of PAREXEL GmbH.

In accordance with its accounting policy for impaired long-lived
assets, management prepared a forecast of PAREXEL GmbH's expected
future cash flows on an undiscounted basis and without interest
charges, based upon assumptions developed by management using PAREXEL
GmbH's historical experience as well as the best estimate of future
trends and events. The sum of the forecasted cash flows from
management's model was less than the carrying amount of PAREXEL's
investment in PAREXEL GmbH.

To assess the fair value of PAREXEL GmbH, a discounted cash flow
valuation technique was utilized with a discount rate of approximately
19.5% based upon PAREXEL GmbH's calculated cost of capital. The
results of this calculation indicated a de minimus valuation; and
accordingly, the Company recorded an impairment loss on long-lived
assets of $11.3 million in fiscal 1995.

NOTE 4.  ACQUISITIONS

In February 1997, the Company acquired, in separate transactions,
RESCON, Inc., a medical marketing consulting business located in the
Washington, D.C. area, and Sheffield Statistical Services, Ltd. (S-
Cubed), a company located in the United Kingdom that specializes in
biostatistical analysis. The Company issued a total of 209,537 shares
of common stock in exchange for all the outstanding shares of RESCON
and S-Cubed.

In August 1996, the Company acquired, in separate transactions, Lansal
Clinical Pharmaceutics, Limited (Lansal), a contract research
organization located in Israel, and State and Federal Associates, Inc.
(S&FA), a medical marketing business located in the Washington, D.C.
area. The Company issued 1,008,304 shares of common stock in exchange
for all of the outstanding shares of Lansal and S&FA.

In June 1996, the Company acquired, in separate transactions, Sitebase
Clinical Systems, Inc. (Sitebase), a provider of remote data entry
technology, and Caspard Consultants (Caspard), a Paris-based
biostatistical and data management consulting company. The Company
issued a total of 161,636 shares of common stock in exchange for all
of the outstanding shares of Sitebase and Caspard.

All of these transactions were accounted for as poolings of interests.
The aggregate historical results of operations and financial position
of the above acquisitions were not material to the Company's
supplemental consolidated financial statements. Therefore, prior
period amounts have not been restated and results of operations of the
acquired companies have been included since the period of acquisition.
Pro forma results of the Company, assuming the above acquisitions were
made at the beginning of each period presented, would not be
materially different from the actual results reported.

NOTE 9.  CREDIT ARRANGEMENTS

The Company has domestic and foreign line of credit arrangements with
banks totaling approximately $14.5 million. The lines are
collateralized by accounts receivable, payable on demand, and bear
interest at varying rates that differ from country to country
(resulting in interest rates ranging from 4.9% to 9.5% at June 30,
1997).  The lines of credit expire at various dates through April 1998
and are renewable.  There was approximately $1.3 million and $600,000
outstanding under these lines of credit at June 30, 1997 and 1996,
respectively.

The Company has a $2.4 million capital lease line of credit with a
U.S. bank for the financing of property and equipment. This line is
collateralized by property and equipment. Borrowings under this line
are payable over a three-year term with interest fixed at the five-
year U.S. Treasury note rate plus 2.5% (8.03% at June 30, 1997). This
line of credit expires on November 30, 1997, and is renewable
annually. Available capacity under this line was approximately $2.0
million at June 30, 1997.

Long-term debt at June 30, 1997 and 1996, consisted of borrowings
under the capital lease line. The fair value of debt is estimated
based on the market value for similar debt and approximates carrying
value at June 30, 1997 and 1996. Aggregate lease obligations bear a
weighted average interest rate of approximately 8.3% at June 30, 1997,
and 7.9% at June 30, 1996. Long-term debt matures as follows: $43,000
in fiscal 1999 and $29,000 in fiscal 2001.

NOTE 10.  STOCKHOLDERS' EQUITY

On January 28, 1997, the Board of Directors of the Company declared a
two-for-one stock split of the Company's common stock, payable in the
form of a 100% stock dividend to be distributed to stockholders of
record as of the close of business on February 7, 1997. All share and
per share data, including stock and stock option, stock purchase plan,
and market price information, included in these supplemental
consolidated financial statements have been restated to reflect the
two-for-one stock split.

As of June 30, 1997 and 1996, there were 5 million shares of preferred
stock, $0.01 per share, authorized, but none were issued or
outstanding. Preferred stock may be issued at the discretion of the
Board of Directors (without stockholder approval) with such
designations, rights and preferences, as the Board of Directors may
determine.

There were 29,412 shares of common stock held in treasury as of June
30, 1997 and 1996, at a cost of $17,430.

NOTE 11.  STOCK AND EMPLOYEE BENEFIT PLANS

Common Stock Options

In September 1995, the Company adopted the 1995 Stock Plan (1995
Plan), which provided for the grant of incentive stock options for the
purchase of up to an aggregate of 1,000,000 shares of common stock to
directors, officers, employees, and consultants of the Company. In
November 1996, the Company's stockholders approved an increase in the
number of shares issuable under the 1995 Plan from 1,000,000 to
2,000,000 shares. The Stock Option Committee of the Board of Directors
is responsible for the administration of the Company's stock option
plans and determines the term of each option, the option exercise
price, number of shares granted, and the rate that options vest.
Options generally expire eight to ten years from the date of grant and
generally vest over four to five years.

In September 1995, the Company adopted the 1995 Non-Employee Director
Stock Option Plan (Director Plan) under which options to purchase an
aggregate of 600,000 shares of common stock may be granted to
nonemployee directors. On November 21, 1995, nonemployee directors
were granted an aggregate of 173,000 options (initial options). The
initial options became exercisable on June 30, 1996. Other options
granted under the Director Plan vest ratably in three equal annual
installments beginning on the first anniversary of the date of grant,
subject to certain requirements as defined in the Director Plan.

In September 1995, the Board of Directors voted to grant no further
options under the 1986 Incentive Stock Option Plan, the 1987 Stock
Plan, and the 1989 Stock Plan and to reduce the number of shares
authorized for those plans to the number of options outstanding at
that time.

In January 1994, the Kemper-Masterson, Inc. Stock Option Plan (the
"Plan") was adopted which provides for the grant of stock options for
the purchase of up to an aggregate of 138,714 shares of Class B common
stock to key employees of KMI. Options under the Plan generally expire
ten years from the date of grant.

In accordance with the provisions of the Plan, KMI grants options
under which the underlying Class B common stock acquired upon exercise
of such options may be subject to repurchase by KMI at certain times
or upon certain events pursuant to the respective stock option
agreements.  For certain options granted ("Formula Options"), KMI has
the right, but not the obligation to repurchase any shares obtained
through the exercise of options granted at the formula price
prescribed in the underlying stock option agreements.  In the event
KMI does not initially elect to repurchase the stock acquired through
Formula Options, the stockholder can sell such stock to a third party
subject to KMI's right of first refusal.  KMI has also granted options
under which KMI is obligated to repurchase upon termination
("Repurchase Options"), shares acquired through the exercise of
previously issued options at the exercise price.  All options have
been granted with an exercise price of $0.17 per share.

All options are being accounted for as a variable options.  For
Formula Options, compensation cost is recognized for the difference
between the formula value of the stock at the date of option exercise
and the exercise price.  Prior to option exercise, compensation cost
is recognized based on the estimated formula value and accrued over
the vesting period.  Changes in the formula value of the stock result
in a change to the measurement of compensation for the options.  For
Repurchase Options, compensation cost is recognized as the difference
between the amount for which the common stock is repurchased by KMI
and the exercise price.  Aggregate compensation expense related KMI's
stock options was $491,000 and $337,000 for fiscal 1997 and 1996
respectively.

Vesting of both the Formula and Repurchase options is accelerated upon
a change in control of  KMI.  Because the exercise price of the
Formula and Repurchase options is considered non-substantive,
compensation expense will be recognized for these options and the
related common shares upon a change in control.  Accordingly, the
Company expects to incur compensation expense of approximately $4.1
million in December 1997, the time at which the Company acquired KMI
in a transaction accounted for as a pooling of interests (Note 16).

Aggregate stock option activity for the two years ended June 30, 1997,

The fair value for options granted was estimated at the time of the
grant using the Black-Scholes option pricing model with the following
weighted-average assumptions for the two years ended June 30, 1997:
Risk free interest rate of 6.18%, dividend yield of 0.0%, volatility
factor of the expected market price of the Company's common stock of
45%, and an average expected life of the option of one year from the
date of vesting. Under these assumptions, the estimated weighted-
average fair value of options granted during the fiscal years ended
June 30, 1997 and 1996, was $12.18 and $7.56, respectively.

Employee Stock Purchase Plan

In September 1995, the Company adopted the 1995 Employee Stock
Purchase Plan (the Purchase Plan). Under the Purchase Plan, employees
have the opportunity to purchase common stock at 85% of the average
market value on the first or last day of the plan period (as defined
by the Purchase Plan), whichever is lower, up to specified limits. An
aggregate of 600,000 shares may be issued under the Purchase Plan.

Had compensation cost for the Company's stock options and the Purchase
Plan been determined based on the fair value at the date of grant, as
prescribed in SFAS 123, the Company's net income and net income per
share would have been as follows:

                    ($ in thousands,        1997       1996
                    except per share data)

                    per share

As stock options vest over several years and additional stock option
grants are expected to be made each year, the above pro forma
disclosures are not necessarily representative of pro forma effects on
reported operations for future years.

401(k) Plan

The Company sponsors an employee savings plan (the Plan) as defined by
Section401(k) of the Internal Revenue Code of 1986, as amended. The
Plan covers substantially all employees in the U.S. who elect to
participate. Participants have the opportunity to invest on a pre-tax
basis in a variety of mutual fund options. The Company matches 100% of
each participant's voluntary contributions up to 3% of gross salary
per payroll period. Company contributions vest to the participants in
20% increments for each year of employment and become fully vested
after five years of continuous employment. Company contributions to
the Plan were $1,053,000, $526,000, and $327,000 for the years ended
June 30, 1997, 1996, and 1995, respectively.

The   net  deferred  tax  assets  are  included  in  the  supplemental
consolidated balance sheet as of June 30, 1997 and 1996, as follows:

                                      $2,918    $1,701

The  net  deferred tax asset includes the tax effect of  approximately
$11  million of pre-acquisition and post-acquisition foreign tax  loss
carryforwards  available  to  offset future  liabilities  for  foreign
income  tax.  Substantially all of the foreign tax losses are  carried
forward  indefinitely,  subject to certain  limitations.  A  valuation
allowance  has  been  established for the future  foreign  income  tax
benefits  primarily  related  to income  tax  loss  carryforwards  and
temporary differences based on management's assessment that it is more
likely  than  not that such benefits will not be realized. Principally
due  to  the  use  of previously reserved foreign net  operating  loss
carryforwards,   the  Company's  valuation  allowance   decreased   to
approximately  $3.4 million at June 30, 1997, from approximately  $5.9
million  at  June 30, 1996. The ultimate realization of the  remaining

NOTE 14.  LEASES

The Company leases its facilities under operating leases which include
renewal  and  escalation clauses. Total rent expense was approximately
$8.4 million, $5.5 million, and $4.7 million for years ended June  30,
1997, 1996, and 1995, respectively. Future minimum lease payments  due

NOTE 15.  RELATED PARTY TRANSACTIONS

Certain  of  the Company's Directors are related with certain  of  the
Company's  customers. Net revenue recognized from these customers  was
$13.1  million, $8.1 million, and $3.0 million in fiscal  1997,  1996,
and  1995,  respectively. Amounts included in accounts  receivable  at
June   30,  1997  and  1996,  were  $3.3  million  and  $1.9  million,
respectively.  Related party amounts included in  accounts  receivable
are on standard terms and manner of settlement.

NOTE 16.  SUBSEQUENT EVENTS

On  September 26, 1997, the Company acquired substantially all of  the
assets  of  Perceptive  Systems, Inc., a  Colorado  corporation  doing
business  as Hayden Image Processing Group ("Hayden") in exchange  for
5,035 shares of the Company's common stock.  In addition, Hayden  will
receive  three annual contingent payments (not exceeding  $228,000  in
aggregate)  of  the  Company's  common  stock,  based  onnet  receipts
generated  by  certain acquired assets. The transaction was  accounted
for as a purchase for financial accounting purposes.

In  November  1997,  the  stockholders  of  the  Company  approved  an
amendment  to  the  Company's 1995 Stock Plan (the "1995  Plan").   In
connection  therewith,  the Company terminated the  1995  Non-Employee
Director  Stock Option Plan (the "Director Plan") and transferred  all
remaining  shares  under the Director Plan to the 1995  Plan,  without
increasing  the aggregate number of shares available for  grant  under
all  of the Company's stock option plans.  The amendment also provides
for  the  annual  formula grant of options to purchase  up  to  15,000
shares  of  common  stock  of  the Company to  non-employee  directors
dependent  upon  the  attendance  by such  non-employee  directors  at
meetings of the Board of Directors and committees thereof.

In  December 1997, the Company acquired Kemper-Masterson, Inc. ("KMI")
in  a  business  combination accounted for as a pooling of  interests.
The  accompanying supplemental consolidated financial statements  have
been retroactively restated to combine the accounts and operations  of
KMI with those of the Company for all periods presented.

Due  to  the  differing year ends of the Company  and  KMI,  financial
information  for  dissimilar fiscal years has been  combined  for  the
Company's fiscal year 1996 and 1995.  KMI's results of operations  for
its  fiscal years ended December 31, 1996 and 1995 were combined  with
the  Company's results of operations for the fiscal years  ended  June
30, 1996 and 1995, respectively.  Balance sheet information as of June
30,  1996  includes the financial position of KMI as of  December  31,
1996  and the Company as of June 30, 1996.  Accordingly, KMI's results
of  operations  for the six months ended December 31, 1996  (including
revenue,  operating income, and net income of $5.0 million,  $167,000,
and $117,000, respectively) were duplicated in the combined statements
of  operations for fiscal 1997 and 1996.  Therefore, KMI's net  income
for  one  of  the  six  month periods ended  December  31,  1996,  was
eliminated from stockholders' equity.

Revenues and  net income  (loss)  for each of the two
 previously separate companies  for
the period prior to the KMI Acquisition are as follows:

                            Year Ended            Three

In  November  1997, the Emerging Issues Task Force  (EITF)  reached  a
consensus on issue 97-13, "Accounting for Costs Incurred in Connection
with  a  Consulting  Contract  or an Internal  Project  that  Combines
Business    Process    Reengineering   and   Information    Technology
Transformation"(EITF  97-13)  that  the  costs  of  business   process
reengineering activities, whether done internally or by third parties,
is  to  be  expensed as incurred.  The consensus also applies  to  the
costs  of  business  process  reengineering  activities  conducted  in
conjunction with a project to acquire, develop, or implement internal-
use  software.   The  transition  provisions  of  EITF  97-13  require
unamortized   previously  capitalized  costs  for   business   process
reengineering  activities to be written off in  the  Company's  fiscal
quarter  ending December 31, 1997 and reported as a cumulative  effect
of a change in accounting principle.  The Company is in the process of
assessing  the impact of EITF 97-13 and does not expect that  it  will
have  a  material affect on its results of operations for the  quarter
ending December 31, 1997.

        SEC Registration fee                      $ 2,979.67
        Nasdaq Additional Listing fee              13,637
        Legal fees and expenses                    20,000
        Accounting fees and expenses               15,000
                                           Total  $51,616.67

      The  Company  will bear all expenses shown above.   All  amounts
other  than the SEC Registration fee and the Nasdaq Additional Listing
fee are estimated solely for the purpose of this offering.

Item 15.  Indemnification of Directors and Officers.

      Article  6  of  the Company's Restated Articles of  Organization
provides that the Company shall indemnify each person who is or was  a
director  or  officer of the Company, and each person who  is  or  was
serving  or  has agreed to serve at the request of the  Company  as  a
director  or  officer  of,  or  in a similar  capacity  with,  another
organization  against all liabilities, costs and  expenses  reasonably
incurred  by  any  such  persons in connection  with  the  defense  or
disposition of or otherwise in connection with or resulting  from  any
action,  suit  or other proceeding in which they may  be  involved  by
reason of being or having been such a director or officer or by reason
of any action taken or not taken in such capacity, except with respect
to  any  matter  as  to  which such person  shall  have  been  finally
adjudicated by a court of competent jurisdiction not to have acted  in
good faith in the reasonable belief that his or her action was in  the
best  interests  of  the Company. Section 67 of Chapter  156B  of  the
Massachusetts  Business Corporation Law authorizes  a  corporation  to
indemnify  its directors, officers, employees and other agents  unless
such  person shall have been adjudicated in any proceeding not to have
acted  in good faith in the reasonable belief that such action was  in
the best interests of the corporation.

     Reference is hereby made to Section 10 of the Registration Rights
Agreements  filed  as  Exhibits  4.3  and  4.5  to  this  Registration
Statement,  for a description of indemnification arrangements  between
the  Company  and  the  Selling Stockholders, pursuant  to  which  the
Selling  Stockholders are obligated, under certain  circumstances,  to
indemnify  directors, officers and controlling persons of the  Company
against   certain   liabilities,  including  liabilities   under   the
Securities Act of 1933, as amended.

   10(a)(3) of the Securities Act of 1933;
              (ii)  to reflect in the prospectus any facts or  events
   arising after the effective date of the registration statement (or
   the   most   recent   post-effective  amendment  thereof)   which,
   individually  or in the aggregate, represent a fundamental  change
   in the information set forth in the registration statement;
              (iii)      to  include  any material  information  with
   respect  to  the plan of distribution not previously disclosed  in
   the   registration  statement  or  any  material  change  to  such
   information in the registration statement;
        (2)  That, for the purpose of determining any liability under
   the  Securities  Act  of 1933, each such post-effective  amendment
   shall be deemed to be a new registration statement relating to the
   securities offered therein, and the offering of such securities at
   that  time  shall be deemed to be the initial bona  fide  offering
   thereof.
         (3)   To remove from registration by means of post-effective
   amendment  any  of  the securities being registered  which  remain
   unsold at the termination of the offering.
(b)   The undersigned registrant hereby undertakes that, for purposes
of  determining any liability under the Securities Act of 1933,  each
filing of the registrant's annual report pursuant to Section 13(a) or
Section  15(d)  of  the  Securities Exchange  Act  of  1934  that  is
incorporated  by  reference in the registration  statement  shall  be
deemed  to be a new registration statement relating to the securities
offered  therein, and the offering of such securities  at  that  time
shall be deemed to be the initial bona fide offering thereof.
(c)   Insofar  as  indemnification for liabilities arising  under  the
Securities  Act  of 1933 may be permitted to directors,  officers  and
controlling  persons  of  the registrant  pursuant  to  the  foregoing
provisions, or otherwise, the registrant has been advised that in  the
opinion of the Securities and Exchange Commission such indemnification
is  against public policy as expressed in the Securities Act  of  1933
and  is,  therefore, unenforceable.  In the event  that  a  claim  for
indemnification against such liabilities (other than  the  payment  by
the registrant of expenses incurred or paid by a director, officer  or
controlling person of the registrant in the successful defense of  any
action,  suit or proceeding) is asserted by such director, officer  or
controlling person in connection with the securities being registered,
the  registrant will, unless in the opinion of its counsel the  matter
has  been  settled  by controlling precedent, submit  to  a  court  of
appropriate jurisdiction the question whether such indemnification  by
it is against public policy as expressed in the Securities Act of 1933
and will be governed by the final adjudication of such issue.

SIGNATURES
          Pursuant to the requirements of the Securities Act of  1993,
as amended, the Registrant certifies that it has reasonable grounds to
believe  that it meets all of the requirements for filing on Form  S-3
and  has  duly caused this Registration Statement on Form  S-3  to  be
signed on its behalf by the undersigned, thereunto duly authorized  in
the  City  of  Waltham, Commonwealth of Massachusetts on  January  __,

                    REORGANIZATION AND MERGER

     2.01.  The Merger.  Subject to the terms and conditions of
this Agreement, the Massachusetts Articles of Merger and the
Delaware Certificate of Merger, Sub shall be merged with and into
the Company in accordance with the applicable provisions of the
laws of the Commonwealth of Massachusetts and the State of
Delaware and with the terms and conditions of this Agreement, the
Massachusetts Articles of Merger and the  Delaware Certificate of
Merger so that:

          (a)  At the Effective Date, Sub shall be merged with
and into the Company.  As a result of the Merger, the separate
corporate existence of Sub shall cease and the Company shall
continue as the surviving corporation (sometimes referred to
herein as the "Surviving Corporation") and shall succeed to and
assume all of the rights and obligations of the Company in
accordance with the laws of the Commonwealth of Massachusetts and
the  State of Delaware.

          (b)  The articles of organization and bylaws of the
Company in effect immediately prior to the Effective Date shall
be the articles of organization and bylaws, respectively, of the
Surviving Corporation after the Effective Date unless and until
further amended as provided by law.

          (c)  The directors and officers of Sub immediately
prior to the Effective Date shall be the directors and officers
of the Surviving Corporation after the Effective Date.  Such
directors and officers shall hold their positions until the
election and qualification of their respective successors or
until their tenures are otherwise terminated in accordance with
the bylaws of Surviving Corporation.

     The Shares that are issued and outstanding immediately prior
to the Effective Date will, by virtue of the Merger and at the
Effective Date, automatically and without further action on the
part of the Stockholders, be converted into such number of shares
of Parent Stock as is equal to the number of Shares held by each
Stockholder (as set forth on Schedule 2.01) multiplied by the
Conversion Ratio (rounded down to the largest whole number of
shares of Parent Stock pursuant to Section 2.07 below).

     Each option evidencing the right to purchase the Option
Shares (each a "Company Option") that is outstanding immediately
prior to the Effective Date shall be exercised by the holder
thereof contemporaneously with the Closing (as hereinafter
defined) and the Option Shares that are outstanding as a result
of such exercise will, by virtue of the Merger and at the
Effective Date, automatically and without further action on the
part of such holder, be converted into such number of shares of
Parent Stock as is equal to the number of Option Shares held by
such Stockholder (as set forth on Schedule 2.01) multiplied by
the Conversion Ratio (rounded down to the largest whole number of
shares of Parent Stock pursuant to Section 2.07 below).

     2.02.  Closing.  The closing (the "Closing") of the
transactions contemplated hereunder shall take place at the
offices of Parent's Counsel in Boston, Massachusetts as soon as
possible after satisfaction of the conditions set forth in
Article X, but in no event later than 11:59 p.m., Boston time, on
December 1, 1997, or at such other time or place as Parent and
the Company may agree.  Simultaneously with the Closing, the
Massachusetts Articles of Merger shall be filed in the office of
the Secretary of State of the Commonwealth of Massachusetts and
the Delaware Certificate of Merger shall be filed in the office
of the Secretary of State of the State of Delaware.  The Merger
shall become effective immediately upon the date stamped by the
Massachusetts Secretary of State on the Massachusetts Articles of
Merger (such date is referred to as the "Effective Date").  At
the Closing, Parent shall deliver to each Stockholder
certificates representing the number of shares of Parent Stock to
which such Stockholder is entitled pursuant to Section 2.01
hereof, less such Stockholder's portion of the "Holdback Shares"
and the "Withholding Shares" (as hereinafter defined).  Each
certificate shall be duly endorsed by the Parent's transfer agent
and registered in the name of each such Stockholder, as is
determined in accordance with Section 2.01.  At the Closing,
Parent shall retain in accordance with the provisions of
Section 11.04 certificates representing the number of shares of
Parent Stock worth $1,000,000 (calculated using the Parent Stock
Price) (rounded up to the nearest whole number of shares) (the
"Holdback Shares") and certificates representing the number of
shares of Parent Stock worth $1,202,093 (calculated using the
Parent Stock Price) (rounded up to the nearest whole number of
shares (the "Withholding Shares"), to be held by the  Parent in
accordance with the provisions of Sections 11.04,  11.05 and
11.06.


     2.03.  Certificates for Parent Stock.  Each certificate for
Parent Stock issued to the Stockholders as part of the Merger
shall bear the following legend:

               "The securities represented hereby have
          not been registered under the Securities Act
          of 1933, as amended, and may not be sold,
          transferred or otherwise disposed of except
          in accordance with the terms thereof and
          unless registered with the Securities and
          Exchange Commission of the United States and
          the securities regulatory authorities of
          certain states or unless an exception from
          such registration is available."

     2.04.  Transfer Taxes.  The Stockholders shall pay any and
all sales, documentary, use, filing, transfer and other taxes
payable as a result of the Merger.

     2.05.  Books and Records.  On or before the Closing Date,
the Company and the Stockholders shall deliver to Parent, or its
representatives, where located, all minute books, stock record
books and corporate seals of the Company, and the original copies
of all books of account, leases, other agreements, securities,
customer lists, files and other documents, instruments and papers
of any kind or nature belonging to or relating to the Company or
its business.

business as now conducted.  The Company is duly qualified to do
business as a foreign corporation and is in good standing in each
jurisdiction in the United States where the character of the
property owned or leased by it or the nature of its activities
make such qualification necessary, except for those jurisdictions
where failure to be so qualified would not, individually or in
the aggregate, have a Material Adverse Effect.  The Company has
heretofore delivered to Parent true and complete copies of the
corporate charter and bylaws, and all amendments thereto, of the
Company.

     3.02.  Corporate Authorization.  The execution, delivery and
performance by the Company of this Agreement and the consummation
by the Company of the transactions contemplated hereby are within

all necessary corporate action on the part of the Company.  This
Agreement constitutes a valid and binding agreement of the
Company.

     3.03.  Governmental Authorization; Consents.

          (a)       The execution and delivery of this Agreement
by the Company and the Stockholders, and the performance by the

     3.04.  Non-Contravention.  The execution and delivery of
this Agreement by the Company and the Stockholders, the

obligations under this Agreement and the consummation of the
transactions contemplated hereby do not and will not (i)
contravene or conflict with the corporate charter or bylaws of
the Company, (ii) contravene or conflict with or constitute a
violation of any provision of any law, regulation, judgment,
injunction, order or decree binding upon or applicable to the
Company; (iii) constitute a default under or give rise to any
right of termination, cancellation or acceleration of any right
or obligation of the Company or to a loss of any benefit to which

All outstanding shares of capital stock of the Company have been

were reserved for issuance upon exercise of stock options granted
pursuant to the Company's Stock Option Plan (the "Company

rights, agreements, arrangements or commitments of any character
to which the Company is a party or by which the Company is bound
relating to the issued or unissued capital stock of the Company
or obligating the Company to issue or sell any shares of capital
stock of, or other equity interests in, the Company.  All shares

Schedule 3.06 have been duly dissolved in accordance with the
laws of their respective jurisdictions of incorporation, in each
case without any liability to the Company.

     3.07.  Financial Statements.  The Company has previously
furnished Parent with a true and complete copy of the balance

Person of any Intellectual Property Rights.  To the knowledge of
the Company and the Principal Stockholders, no Intellectual
Property Right is subject to any outstanding order, judgment,
decree, stipulation or agreement restricting the use thereof by
the Company or restricting the licensing thereof by the Company
to any Person.  The Company has not entered into any agreement to
indemnify any other Person against any charge of infringement of
any patent, trademark, service mark or copyright.

          (c)  None of the Intellectual Property Rights of the

          (e)  None of the former or present employees, officers,
directors, consultants or contractors of the Company holds any
right, title or interest, directly or indirectly, in whole or in
part, in or to any of the Intellectual Property Rights which the

knowledge of the Company and the Principal Stockholders, no
employee of the Company is in violation of any term of any
employment contract, patent disclosure agreement or any other
contract or agreement relating to the relationship of any such
employee with the Company or any other party because of the
nature of the business conducted by the Company.  No person has

adapting, revising, translating, adding to or subtracting from
any of the Intellectual Property Rights owned by the Company,
(ii) doing any of the foregoing without obligation to name the

Sections 280G(b)(4) and 280G(b)(5) of the Code) or (ii) any
payments or other transactions that would be, in whole or in
part, nondeductible under Sections 162 or 404 of the Code.  The

     or safety (collectively, "Environmental Laws") and the
     Stockholders and the Company have not received any notice of
     non-compliance with Environmental Laws;
     
          (ii) none of the Stockholders or the Company have

     compliance with Environmental Laws; and
     
          (iii)     there are no "Environmental Liabilities".
     For purposes of this Agreement, "Environmental Liabilities"

     relate to the Company or any real estate at any time owned,
     used or leased by the Company, or the Company's or any
     Stockholder's use or ownership thereof, whether vested or
     unvested, contingent or fixed, actual or potential, and
     (z) arise from or relate to actions occurring (including any
     failure to act) or conditions existing on or before the
     Closing Date.

     3.21.  Customers and Suppliers. Schedule 3.21 sets forth an
accurate list of the Company's twenty (20) largest customers by
revenue.  The Company and the Stockholders have not received
notice from or otherwise have knowledge that any group of
customers who are under common ownership or control and who
accounted as a group for a material percentage of the aggregate
products and services furnished by the Company during the past 18
months has stopped or intends to stop purchasing the Company's
products or services nor has the Company lost any supplier or
group of suppliers, which accounted for a material percentage of
the aggregate supplies purchased by the Company during the past
18 months.

     3.22.  Transactions with Affiliates.  Except as set forth on
Schedule 3.22, there are no loans, leases, royalty agreements or
other continuing transactions between the Company and any
Stockholder, any Affiliate of any Stockholder, or any member of
any Stockholder's family.  Except as set forth on Schedule 3.22,
to the best knowledge of the Company and the Principal
Stockholders, none of the officers or directors of the Company or
Stockholder (a) has any material direct or indirect interest in
any entity which does business with the Company; (b) has any
direct or indirect interest in any property, asset or right which
is used by the Company in the conduct of its business; or (c) has
any contractual relationship with the Company other than such
relationships which occur from being an officer, director or
stockholder of the Company.

     3.23.  Other Information.  None of the documents or
information delivered to Parent in connection with the
transactions contemplated by this Agreement contains any untrue
statement of a material fact or omits to state a material fact
necessary in order to make the statements contained therein not
misleading.  The Kemper-Masterson, Inc. August 15, 1997 Forecast
and accompanying information relating to the projected future
performance of the Company delivered to Parent constitute the
Company's and the Principal Stockholders' best estimate of the
information purported to be shown therein, and the Company and
the Principal Stockholders are not aware of any fact or
information that would lead them to believe that such projections
are incorrect or misleading in any material respect.  The results
forecast in the above-referenced document are estimates and the
Company and the Principal Stockholders cannot guarantee that any
particular result will be achieved.

     3.24.  Intercompany Arrangements.  Except as set forth on
Schedule 3.24, the Company does not own any note, bond, debenture
or other indebtedness, and is not otherwise a creditor, of any
Stockholder or any of his or its Affiliates.  Since the Balance
Sheet Date there has not been any payment by the Company to any
Stockholder or any of his or its Affiliates, charge by any
Stockholder or any of his or its Affiliates to the Company or
other transaction between the Company and any Stockholder and any
of his or its Affiliates, except in any such case in the ordinary
course of business of the Company consistent with past practice.

     3.25.  Employees.  Schedule 3.25 sets forth a true and
complete list of (a) the names, titles, annual salaries and other
compensation of all employees of the Company and (b) the wage
rates for non-salaried employees of the Company (by
classification).  None of such employees and no other employee of
the Company has indicated to the Company or any Stockholder that
he intends to resign, retire or file a claim or otherwise bring
an action against the Company, Parent or Sub as a result of the
transactions contemplated by this Agreement or otherwise.

     The Company and each Stockholder agree that:

     6.01.  Confidentiality.  The Company, such Stockholder and
their Affiliates will hold, and will use reasonable efforts to
cause their respective officers, directors, employees,
accountants, counsel, consultants, advisors and agents to hold,
in confidence, unless compelled to disclose by judicial or
administrative process or by other requirements of law, all
confidential documents and information concerning Parent or Sub
furnished to the Company, such Stockholder or their Affiliates in
connection with the transactions contemplated by this Agreement,
and (after the Closing Date) all confidential documents and
information concerning the Company, except to the extent that
such information can be shown to have been (i) previously known
on a nonconfidential basis by such Stockholder, (ii) in the
public domain through no fault of such Stockholder or (iii) later
lawfully acquired by such Stockholder from sources other than the
Company, Parent or Sub; provided that the Company and such
Stockholder may disclose such information to their respective
officers, directors, employees, accountants, counsel,
consultants, advisors and agents in connection with the
transactions contemplated by this Agreement so long as such
persons are informed by the Company and such Stockholder of the
confidential nature of such information and are directed by the
Company and such Stockholder to treat such information
confidentially.  The obligation of the Company, such Stockholder
and their Affiliates to hold any such information in confidence
shall be satisfied if they exercise the same care with respect to
such information as they would take to preserve the
confidentiality of their own similar information.  If this
Agreement is terminated, the Company, such Stockholder and their
Affiliates will, and will use their best efforts to cause their
respective officers, directors, employees, accountants, counsel,
consultants, advisors and agents to, destroy or deliver to
Parent, upon request, all documents and other materials, and all
copies thereof, obtained by the Company, such Stockholder or
their Affiliates or on their behalf from Parent or Sub in
connection with this Agreement that are subject to such
confidence.

     6.02.  Affiliate Agreements.  The Company shall deliver to
Parent on or prior to the date of this Agreement a letter from
Company Counsel, satisfactory in form and substance to Parent's
Counsel, which, based upon discussion with the Company and such
inquiries as such firm deems necessary, shall identify all
persons who, at the date of this Agreement, such firm believes
may be deemed to be "affiliates" of the Company as such term is
used in and for the purposes of Accounting Series Releases 130
and 135, as amended, of the Securities and Exchange Commission,
and defined in Rule 144(a)(1) of the Securities Act of 1933, as
amended, and who will become the beneficial owners of shares of
Parent Stock pursuant to the transactions contemplated by this
Agreement (each such person being referred to as a "Company
Affiliate"). The Company shall deliver to Parent on or prior to
the Closing Date a letter from Company Counsel, satisfactory in
form and substance to Parent's Counsel, which shall identify all
Company Affiliates as of the Closing Date.  The Company shall
cause each of the Company Affiliates to execute and deliver to
Parent (i) on the date of this Agreement and (ii) on the Closing
Date, a written agreement (the "Affiliate Agreement")
satisfactory to Parent and substantially in the form of Exhibit E
hereto, including provisions indicating that such Company
Affiliate (i) has not offered to sell, sold or otherwise disposed
of any Shares in the 30 day period prior to the date hereof,
(ii) will not offer to sell, sell or otherwise dispose of any
shares of Parent Stock, except pursuant to an effective
registration statement or in compliance with an available
exemption from the registration requirements of the Securities
Act (for which Stockholder shall provide Parent with an opinion
of counsel satisfactory to Parent that the securities being sold
thereby may be publicly sold without registration under the
Securities Act), and (iii) will not offer to sell, sell or
otherwise dispose of any shares of Parent Stock until Parent
shall have publicly released financial results covering a period
of at least 30 days of post-closing combined operations of Parent
and the Company.

     6.03.  Expenses.  The Stockholders shall pay, prior to or at
the Closing, all costs and expenses incurred by the Company or
the Stockholder in connection with this Agreement.

     6.04.  Satisfaction of Parent's Withholding Obligation.

to Parent, in immediately available funds (through wire transfer
or federal funds check) not later than 12:00 noon, Eastern
Standard Time, on the tenth business day after the Lapse Date (as
defined below), the federal, state, local and foreign tax
withholding amounts attributable to the Parent Stock issued to
him with respect to the Option Shares, including without
limitation federal, state, local and foreign income tax, Social
Security and Medicare tax withholding and similar amounts
(excluding the employer's portion of such amounts), at the
applicable tax withholding rates, all as determined by Parent and
its accountants.  Each Stockholder agrees to cooperate fully and
to follow any reasonable instructions with respect to such tax
withholding obligation, and each understands that the fair market
value of the Parent Stock received in exchange for the Option
Shares must be reported as compensation for tax purposes, such
compensation being reported as of the Lapse Date.  For purposes
of this Section 6.04, Lapse Date shall mean the first business
day following the date the Parent Stock issued to such person
pursuant to this Agreement is no longer subject to a restriction
on transfer pursuant to the "pooling of interests" accounting
rules.

efforts to cause each person who, at the date of this Agreement,
Parent believes may be deemed to be "affiliates" of Parent as
such term is used in and for the purposes of Accounting Series
Releases 130 and 135, as amended, of the Securities and Exchange
Commission, and defined in Rule 144(a)(1) of the Securities Act

deliver on the Closing Date, an Affiliate Agreement substantially
in the form of Exhibit G hereto.

     7.04.  Reorganization Status.  Parent shall consistently
treat for all United States federal income tax purposes the
Merger as a reorganization, within the meaning of Section 368(a)
of the Code.

     7.05.  Business Continuity.  Parent shall either continue to
conduct the historic business of the Company or shall continue to
use the historic assets of the Company in a business.

     7.06.  Confidentiality.  Until the Closing Date, Parent and
Sub and their Affiliates will hold, and will use reasonable
efforts to cause their respective officers, directors, employees,
accountants, counsel, consultants, advisors and agents to hold,
in confidence, unless compelled to disclose by judicial or
administrative process or by other requirements of law, all
confidential documents and information concerning the Company
furnished to the Parent or Sub or their Affiliates in connection
with the transactions contemplated by this Agreement, except to
the extent that such information can be shown to have been

Agreement so long as such persons are informed by the Parent or
Sub of the confidential nature of such information and are
directed by the Parent or Sub to treat such information
confidentially.  The obligation of the Parent and Sub and their
Affiliates to hold any such information in confidence shall be
satisfied if they exercise the same care with respect to such
information as they would take to preserve the confidentiality of
their own similar information.  If this Agreement is terminated,
the Parent and Sub and their Affiliates will, and will use their
best efforts to cause their respective officers, directors,
employees, accountants, counsel, consultants, advisors and agents
to, destroy or deliver to the Company, upon request, all
documents and other materials, and all copies thereof, obtained
by the Parent and Sub or their Affiliates or on their behalf from
the Company in connection with this Agreement that are subject to
such confidence.

     7.07.  Publication of Interim Financial Results.  Parent
will use good faith commercially reasonable efforts to cause
interim financial results covering thirty (30) days beginning
December 1, 1997 (or December 2, 1997 if the Closing occurs on
December 1, 1997) to be published as promptly as reasonably
practicable following the Closing.

     7.08.  Nasdaq National Market Additional Shares
Notification.  Parent will file an additional share notification
with the Nasdaq National Market to approve for listing the shares

contributed or the benefit of any current or former employee of
the Company (other than routine claim for benefit) is pending.

          (l)  There is no contract, agreement, plan or
arrangement covering any employee or former employee of the
Company that, individually or collectively, could give rise to

Article IX shall create any third party beneficiary or other
rights in any employee or former employee (including any
beneficiary or dependent thereof) of the Company in respect of
continued employment (or resumed employment) with the Company and
no provision of this Article IX shall create any such rights in
any such Persons in respect of any benefits that may be provided,
directly or indirectly, under any Employee Plan or Benefit
Arrangement or any plan or arrangement that may be established by
Parent or any of its Affiliates.  No provision of this Agreement
shall constitute a limitation on rights to amend, modify or
terminate after the Closing Date any Employee Plan or Benefit
Arrangement.

     11.01.  Survival. The covenants contained in this Agreement
shall survive the Closing and continue until the date set forth
in each such covenant.  The agreements, representations and
warranties contained in this Agreement shall survive the Closing
until the earlier of (i) the delivery by Price Waterhouse LLP of
its report on Parent's financial statements for the fiscal year
ended June 30, 1998 or (ii) the one (1) year anniversary of the
Closing Date.  Notwithstanding the preceding sentences, any
covenant, agreement, representation or warranty in respect of
which indemnity may be sought under Section 11.02 shall survive
the time at which it would otherwise terminate pursuant to the
preceding sentences, if notice of the inaccuracy or breach
thereof giving rise to such right to indemnity shall have been
given to the party against whom such indemnity may be sought
prior to such time.

     11.02.  Indemnification

       (a)     Each Principal Stockholder, jointly and severally,
and each Stockholder who is not a Principal Stockholder,
severally, hereby indemnifies Parent, Sub, and their respective
subsidiaries, directors, officers, agents and affiliates and,
effective at the Closing, without duplication, the Company
(collectively, the "Parent Group") against and agrees to defend
and hold them harmless from any and all damage, loss, liability
and expense (including without limitation reasonable expenses of
investigation and reasonable attorneys' fees and expenses in
connection with any action, suit or proceeding) ("Damages")
incurred or suffered by Parent, Sub or the Company arising out of
(i) any inaccuracy in or breach or alleged breach of any
agreement, representation or warranty of the Company (with
respect to the Principal Stockholders only) or such Stockholder
contained in or made pursuant to this Agreement or any
certificate or other writing delivered pursuant hereto or in
connection herewith, (ii) any failure by such Stockholder or the
Company (with respect to the Principal Stockholders only) to
perform any of their respective obligations or covenants as set
forth in this Agreement or any certificate or other writing
delivered pursuant hereto or in connection herewith, (iii) any
and all actions, suits, litigation, arbitrations, proceedings,
investigations or claims arising out of any of the foregoing and
based on facts that have occurred on or prior to the Closing Date
even though such action, suit, litigation, arbitration,
proceeding, investigation or claim may not be filed or come to
light until after the Closing Date and (iv) any and all actions,
suits, litigation, arbitrations, proceedings, investigations or
claims filed or made by Paul Stanovich, L.G.M. Technical
Enterprises, Ltd., Bruce Fowler, Ken Chapman or Drumbeat
Dimensions, Inc. (collectively, the "Claims"); provided that the
Stockholders shall not be liable under this Section 11.02(a)
unless the aggregate amount of Damages with respect to all
matters referred to in this Section 11.02(a) exceeds $25,000;
provided, further, that (i) once the Damages exceed $25,000, the
Parent Group shall be entitled to indemnification for the full
amount of such Damages and (ii) such indemnity obligations shall
be satisfied by the Stockholders by transferring to Parent shares
of Parent's common stock owned by the Stockholders having a
value, as of the date hereof, equal to the amount of such Damages
(any deficiency to be paid by such Stockholder in cash).  The
maximum liability of all the Stockholders, in the aggregate,
pursuant to this Section 11.02(a) shall be the number of shares
of Parent Stock received by the Stockholders (or the value
thereof as of the Closing Date if previously sold) having an
aggregate value, as of the date hereof, of $10,000,000.

       (b) The Stockholders shall have no right of
indemnification, contribution or subrogation against the Company
with respect to any indemnification by the Stockholders under
this Section 11.02 if the transactions contemplated by this
Agreement are consummated.

       (c) Parent hereby indemnifies the Stockholders, their
respective agents and affiliates (the "Selling Group") against
and agrees to defend and hold them harmless from any and all
Damages incurred or suffered by the Selling Group arising out of
any misrepresentation or breach of warranty, covenant or
agreement made or to be performed by Parent pursuant to this
Agreement, such indemnity obligations to be satisfied by Parent
by issuing shares of its common stock having a value, as of the
date hereof, equal to the amount of such Damages, provided,
however, that such amount in the aggregate shall in no event
exceed $10,000,000.

   11.03. Procedures.  The party seeking indemnification under
Section 11.02 (the "Indemnified Party") agrees to give prompt
notice to the party against whom indemnity is sought (the
"Indemnifying Party") of the assertion of any claim, or the
commencement of any suit, action or proceeding in respect of
which indemnity may be sought under such Section.  The
Indemnifying Party may, and at the request of the Indemnified
Party shall, participate in and control the defense of any third
party suit, action or proceeding at its own expense.  The
Indemnifying Party shall not be liable under Section 11.02 for
any settlement effected without its consent (which may not be
unreasonably withheld or delayed) of any claim, litigation or
proceeding in respect of which indemnity may be sought hereunder.

   11.04.  Holdback and Withholding Shares.  At the Closing, the
Stockholders shall be deemed to have directed Parent to withhold
from delivery the Holdback Shares and the Withholding Shares.
The Holdback Shares and the Withholding Shares shall be issued to
the Stockholders but held in escrow by Parent subject to the
terms and conditions hereinafter set forth.  Holdback Shares and
the Withholding Shares shall be considered issued and outstanding
shares of capital stock of Parent and the Stockholders shall be
entitled to vote such shares and receive any and all dividends or
distributions payable with respect to such shares.

   11.05.  Holdback Termination. The Holdback Shares shall be
distributed to the Stockholders as follows:

       (a) Within 30 days after the earlier to occur of (i) the
delivery by Price Waterhouse LLP of its report on Parent's
financial statements for the fiscal year ended June 30, 1998 or
(ii) the one (1) year anniversary of the Closing Date, the
Holdback Shares shall be distributed to the Stockholders, except
that the portion of the Holdback Shares having a value as of the
date hereof most nearly equal to the Damages incurred by Parent
as to which a Claim shall have been previously and duly delivered
to the Stockholders shall continue to be withheld in escrow.

       (b) The value of a Holdback Share as of the  date hereof
shall be equal to the Parent Stock Price (subject to appropriate
adjustment in the event of a stock split or reverse stock split).
The amount of such Damages shall be based upon a written
certification of the Chief Executive Officer of Parent to the
Stockholders as to the amount of Damages incurred, together with
supporting documentation.  If the Stockholders disagree with the
amount of Damages set forth in such certificate, and if the
Stockholders and Parent cannot reach a mutually satisfactory
understanding with regard to the amount of Damages within five
(5) business days after delivery of the certificate to the
Stockholders, the matter shall be promptly submitted to binding
arbitration in Boston, Massachusetts in accordance with the rules
of the American Arbitration Association.  The balance of the
Holdback Shares not so withheld shall be distributed to the
Stockholders.

       (c) The Holdback Shares not so distributed to the
Stockholders pursuant to subsection 11.05(a) and 11.05(b) shall
be retained by Parent in escrow until such pending Claims are
resolved; provided, however, that upon the disposition of any
such Claim prior to the disposition of all such Claims, Parent
shall distribute to the Stockholders that amount of the Holdback
Shares having a value as of the  date hereof in excess of 100% of
the aggregate amounts of the remaining Damages incurred as
determined above.

   11.06.  Withholding Termination.

       (a) Within 25 business days after the Lapse Date (as
defined in Section 6.04), the Withholding Shares shall be
distributed to the Stockholders, except that the portion of the
Withholding Shares having a value as of the date hereof most
nearly equal to the Damages incurred by Parent as a result of or
relating to a breach of the provisions of Section 6.04 hereof
shall continue to be held in escrow.

       (b) The value of the Withholding Shares as of the  date
hereof shall be equal to the Parent Stock Price (subject to
appropriate adjustment in the event of a stock split or reverse
stock split).  The amount of such Damages shall be based upon a
written certification of the Chief Executive Officer of Parent to
the Stockholders as to the amount of Damages incurred, together
with supporting documentation.  If the Stockholders disagree with
the amount of Damages set forth in such certificate, and if the
Stockholders and Parent cannot reach a mutually satisfactory
understanding with regard to the amount of Damages within five
(5) business days after delivery of the certificate to the
Stockholders, the matter shall be promptly submitted to binding
arbitration in Boston, Massachusetts in accordance with the rules
of the American Arbitration Association.  The balance of the
Withholding Shares not so withheld shall be distributed to the
Stockholders.

       (c) The Withholding Shares not so distributed to the
Stockholders pursuant to subsection 11.06(a) and 11.06(b) shall
be retained by Parent in escrow until such pending Claims are
resolved; provided, however, that upon the disposition of any
such Claim prior to the disposition of all such Claims, Parent
shall distribute to the Stockholders that amount of the
Withholding Shares having a value as of the  date hereof in
excess of 100% of the aggregate amounts of the remaining Damages
incurred as determined above.

                  REGISTRATION RIGHTS AGREEMENT

   AGREEMENT dated as of December 1, 1997 among PAREXEL
International Corporation, a Massachusetts corporation (the
"Company") and Clarence A. Kemper, P. Michael Masterson, Mark A.
Lester, Ronald Tetzlaff, Alan R. Parenteau, Warren Handren, David
Hyde and Jon R. Voss (individually, a "Stockholder," and
collectively, the "Stockholders").

                      W I T N E S S E T H :

   WHEREAS, pursuant to the Agreement and Plan of Reorganization
and Merger dated as of October 22, 1997 (the "Merger Agreement")
among the Company, KMI Acquisition Corporation, a Massachusetts
corporation ("Sub"),  Kemper-Masterson, Inc., a Delaware
corporation ("KMI") and the other parties named therein, Sub will
be merged with and into KMI and KMI will become a wholly-owned
subsidiary of the Company;

   WHEREAS, in connection therewith, the Stockholders will
receive unregistered shares of Common Stock of the Company (the
"Shares"); and

   WHEREAS, the Company and the Stockholders wish to set forth
certain rights and obligations with regard to the registration of
the Shares;

   NOW, THEREFORE, the parties hereto agree as follows:

     1.   Certain Definitions.  As used in this Agreement, the
following terms shall have the following respective meanings:

        "Commission" shall mean the Securities and Exchange
   Commission, or any other federal agency at the time
   administering the Securities Act.

        "Shares" shall mean the shares of Common Stock of the
   Company issued to the Stockholders on even date herewith
   pursuant to the Merger Agreement.

        "Common Stock" shall mean the Common Stock, $.01 par
   value, of the Company, as constituted as of the date of this
   Agreement.

        "Exchange Act" shall mean the Securities Exchange Act of
   1934, as amended, or any successor federal statute, and the
   rules and regulations of the Commission thereunder, all as
   the same shall be in effect at the time.

        "Registration Expenses" shall mean the expenses so
   described in Section 9.

        "Securities Act" shall mean the Securities Act of 1933,
   as amended, or any successor federal statute, and the rules
   and regulations of the Commission thereunder, all as the same
   shall be in effect at the time.

        "Selling Expenses" shall mean the expenses so described
   in Section 9.

     2.   Compliance with Securities Laws.  The Stockholders
represent and warrant that they:

          (a)  have paid no brokerage or similar commissions in
connection with the acquisition of the Shares.

          (b)  are acquiring such Shares solely for their own
account.

          (c)  have provided such information as may reasonably
have been requested by the Company in order for the Company or
its counsel to evaluate the availability of an exemption under
the Securities Act for the issuance of the Shares to the
Stockholders.

     3.   Securities Act Matters.  The Stockholders acknowledge
and agree that the Shares have not been registered under the
Securities Act or under the securities laws of any state, in
reliance upon certain exemptive provisions of such statutes.  The
Stockholders recognize and acknowledge that such claims of
exemption are based, in part, upon the Stockholders'
representations contained in this Agreement.  The Stockholders
further recognize and acknowledge that, because the Shares are
unregistered under federal and state laws, they are not presently
eligible for public resale, and may only be resold in the future
pursuant to an effective registration statement under the
Securities Act and any applicable state securities laws, or
pursuant to a valid exemption from such registration
requirements.  The Stockholders recognize and acknowledge that
Rule 144 (which facilitates routine sales of securities in
accordance with the terms and conditions of that Rule, including
a holding period requirement) is not now available for resale of
the Shares, and the Stockholders recognize and acknowledge that,
in the absence of the availability of Rule 144, a sale pursuant
to a claim of exemption from registration under the Securities
Act would require compliance with some other exemption under the
Securities Act, which may not be available for resale of the
Shares.  The Stockholders recognize and acknowledge that, except
as set forth in this Agreement, the Company is under no
obligation to register the Shares, either pursuant to the
Securities Act or the securities laws of any state.

     4.   Restrictive Legend.  Each certificate representing
Shares shall, except as otherwise provided in this Section 4 or
in Section 5, be stamped or otherwise imprinted with a legend
substantially in the following form:

          "The Securities represented hereby have not been
     registered under the Securities Act of 1933, as
     amended, and may not be sold, transferred or otherwise
     disposed of except in accordance with the terms thereof
     and unless registered with the Securities and Exchange
     Commission of the United States and the securities
     regulatory authorities of certain states or unless an
     exemption from such registration is available."

     Such certificates shall not bear such legend if in the
opinion of counsel satisfactory to the Company the securities
being sold thereby may be publicly sold without registration
under the Securities Act or if such securities have been sold
pursuant to Rule 144, any other exemption under the Securities
Act or an effective registration statement.

     5.   Notice of Proposed Transfer.  Prior to any proposed
transfer of any Shares before the expiration of the applicable
holding period set forth in Rule 144, each Stockholder shall give
written notice to the Company of his intention to effect such
transfer.  Prior to any registration statement described in
Section 6 becoming effective, each such notice shall describe the
manner of the proposed transfer and, if requested by the Company,
shall be accompanied by an opinion of counsel satisfactory to the
Company to the effect that the proposed transfer may be effected
without registration under the Securities Act, whereupon the
Stockholder shall be entitled to transfer such security in
accordance with the terms of his notice.  Each certificate for
Shares transferred as above provided shall bear the legend set
forth in Section 4, except that such certificate shall not bear
such legend if (i) such transfer is in accordance with the
provisions of Rule 144 (or any other rule permitting public sale
without registration under the Securities Act), (ii) such
transfer is pursuant to a registration under the Securities Act,
or (iii) the opinion of counsel referred to above is to the
further effect that the transferee and any subsequent transferee
(other than an affiliate of the Company) would be entitled to
transfer such securities in a public sale without registration
under the Securities Act.

     6.   Required Registration.  The Company agrees to use
commercially reasonable efforts to (i) cause a registration
statement on Form S-3 (the "Initial Registration Statement") or
any successor form thereto under the Securities Act relating to
the resale of fifty percent (50%) of the Shares to be filed no
later than the 90th day following the date of the Merger
Agreement; (ii) cause a registration statement on Form S-3 or any
successor form thereto under the Securities Act (or an amendment
to the Initial Registration Statement) relating to the resale of
the remaining fifty percent (50%) of the Shares (including all of
the Holdback Shares) to be filed approximately 180 days after the
filing date of the Initial Registration Statement; and (iii)
cause the Initial Registration Statement to become effective as
soon as practicable after the filing of the Initial Registration
Statement and thereafter remain effective until the earlier of
(A) one year after the date of the Merger Agreement or (B) the
sale of all Shares covered thereby.  Anything to the contrary
herein notwithstanding, the Company shall not be required to take
any action to cause any registration statement to be declared
effective by the Commission at any time prior to the publication
by the Company of financial results including at least thirty
(30) days' post-closing combined operating results of the Company
and KMI (the "Pooling Restricted Period"), and the Company may
suspend sales in accordance with Section 8 at any time under any
registration statement immediately upon written notice to the
Stockholders at their last known address, for any of the reasons
and for the time periods set forth in Section 8.

     7.   Registration Procedures.  If and whenever the Company
is required by the provisions of Section 6 to use commercially
reasonable efforts to effect the registration of any Shares under
the Securities Act, the Company will, as expeditiously as
possible:

          (a)  prepare and file with the Commission such
amendments and supplements to the applicable registration
statement, and the prospectus used in connection therewith, as
may be necessary to comply with the Securities Act;

          (b)  furnish to the Stockholders such number of copies
of the relevant registration statement and each amendment and
supplement thereto (in each case including exhibits) and the
prospectus included therein (including each preliminary
prospectus) as they reasonably may request in order to facilitate
the public sale or other disposition of the Shares covered by
such registration statement;

          (c)  register or qualify the Shares covered by the
applicable registration statement under the securities or "blue
sky" laws of the jurisdictions where the Company is currently
registered or qualified, provided, however, that the Company
shall not for any such purpose be required to qualify generally
to transact business as a foreign corporation in any jurisdiction
where it is not so qualified or to consent to general service of
process in any such jurisdiction;

          (d)  have the Shares covered by the applicable
registration statement subject to quotation on the Nasdaq
National Market; and

          (e)  promptly notify each Stockholder (at his last
known address) (i) of the effective date of the applicable
registration statement and the date when any post-effective
amendment to such registration statement becomes effective, (ii)
of any stop order or notification from the Commission or any
other jurisdiction as to the suspension of the effectiveness of
such registration statement, or (iii) of the institution and
ending of any suspension under Section 8.

     8.   Suspension.

          (a)  The rights of the Stockholders to resell the
Shares pursuant to this Agreement and the applicable registration
statement may be suspended by the Company on the occurrence of
any of the following events:

               (i)  the Company has made a determination to
     conduct a public offering;
               (ii) the Company is about to make a public
     disclosure of information of a material nature;
     
               (iii)     there then exists material, non-public
     information relating to the Company which, in the good faith
     determination of its Board of Directors, the disclosure of
     which would not be in the interests of the Company or its
     stockholders during that time; or
     
               (iv) the Company is engaged in any activity at any
     time that, in the good faith determination of its Board of
     Directors, would be adversely affected by the continued
     compliance with this Agreement or the continued distribution
     of the Shares by the Stockholders.

          (b)  The Company shall use commercially reasonable
efforts to minimize the length of any suspension:

               (i) under Section 8(a)(i), to a period of thirty
(30) days, beginning on the day that notice of a suspension is
given to the Stockholders and ending on the earlier of:  (A) the
date of disclosure of the public offering, or (B) the date which
is 30 days after the beginning of the suspension, provided that
during such suspension, the Company will proceed with
commercially reasonable efforts to file the appropriate
documentation in respect of, and otherwise complete, such public
offering as expeditiously as practicable;

               (ii) under Section 8(a)(ii), to a period of three
(3) business days;

               (iii)     under Section 8(a)(iii) or 8(a)(iv), if
the activity is a prospective acquisition by the Company, to a
period beginning when the notice of suspension is given to the
Stockholders and ending on the earliest of:  (A) the date on
which the Company publicly announces the acquisition, (B) the
closing of the transaction and the making of all required filings
under the Securities Act or Exchange Act, or (C) the date on
which discussions regarding the acquisition are terminated; and

               (iv) under Section 8(a)(iii) or 8(a)(iv), for any
reason other than a prospective acquisition by the Company, to a
period beginning when the notice of suspension is given to the
Stockholders and ending on the earlier of:  (A) the disclosure of
the activity, or (B) the reason is no longer operative (provided,
however, that the Company shall not avail itself of the
suspension rights contained in Section 8(a)(iv) more than once in
every six (6) month period commencing on the date of
effectiveness of the Registration Statement).

     9.   Expenses.  All expenses incurred by the Company in
complying with Section 6, including, without limitation, all
registration and filing fees, printing expenses, fees and
disbursements of counsel and independent public accountants for
the Company, fees and expenses incurred in connection with
complying with state securities or "blue sky" laws, fees of the
National Association of Securities Dealers, Inc., transfer taxes,
fees of transfer agents and registrars, and costs of issuance,
but excluding any Selling Expenses, are called "Registration
Expenses".  All underwriting discounts (if any) and selling
commissions applicable to the sale of the Shares covered by any
registration statement, as well as all professional service fees
incurred by the Stockholders, are called "Selling Expenses".

     All Selling Expenses shall be borne by the Stockholders.
The Company will pay all Registration Expenses in connection with
the preparation and filing of each registration statement.  The
Company shall not be obligated to pay any Registration Expenses
in connection with the preparation and filing of any registration
statement if such registration statement is withdrawn, delayed or
abandoned for any reason by the Stockholders.

     10.  Indemnification and Contribution.

          (a)  In connection with the registration of the Shares
under the Securities Act pursuant to Section 6, the Company will
indemnify and hold harmless each Stockholder, each underwriter of
such Shares thereunder and each other person, if any, who
controls such underwriter within the meaning of the Securities
Act, against any losses, claims, damages or liabilities, joint or
several, to which such Stockholder, underwriter or controlling
person may become subject under the Securities Act, Exchange Act,
state securities laws or otherwise, insofar as such losses,
claims, damages or liabilities (or actions in respect thereof)
arise out of or are based upon (i) any untrue statement or
alleged untrue statement of material fact contained in the
registration statement under which such Shares were registered
under the Securities Act pursuant to Section 6, any preliminary
prospectus or final prospectus contained therein, or any
amendment or supplement thereto, (ii) the omission or alleged
omission of a material fact required to be stated therein or
necessary to make the statements therein not misleading or
(iii) any violation by the Company or its agents of any rule or
regulation promulgated under the Securities Act, Exchange Act or
state securities laws applicable to the Company or its agents and
relating to action or inaction required of the Company in
connection with such registration, and the Company will reimburse
each such Stockholder, each such underwriter and each such
controlling person for any legal or other expenses reasonably
incurred by them in connection with investigating or defending
any such loss, claim, damage, liability or action, as such
expenses are incurred, provided, however, that the Company will
not be liable in any such case if and to the extent that any such
loss, claim, damage or liability arises out of or is based upon
an untrue statement or alleged untrue statement or omission or
alleged omission so made based upon information furnished by any
such Stockholder, any such underwriter or any such controlling
person.

          (b)  In connection with the registration of the Shares
under the Securities Act pursuant to Section 6, the Stockholders
will indemnify and hold harmless the Company, each person, if
any, who controls the Company within the meaning of the
Securities Act, each officer of the Company who signs such
registration statement, each director of the Company, each
underwriter and each person who controls any underwriter within
the meaning of the Securities Act, against all losses, claims,
damages or liabilities, joint or several, to which the Company or
such officer, director, underwriter or controlling person may
become subject under the Securities Act or otherwise, insofar as
such losses, claims, damages or liabilities (or actions in
respect thereof) arise out of or are based upon (i) the failure
of the Stockholders to comply with the provisions of Section 13
herein or (ii) any untrue statement or alleged untrue statement
of any material fact contained in the registration statement, any
preliminary prospectus or final prospectus contained therein, or
any amendment or supplement thereto, or (iii) the omission or
alleged omission to state therein a material fact required to be
stated therein or necessary to make the statements therein not
misleading, and will reimburse the Company and each such officer,
director, underwriter and controlling person for any legal or
other expenses reasonably incurred by them in connection with
investigating or defending any such loss, claim, damage,
liability or action, as such expenses are incurred, provided,
however, that the Stockholders will be liable hereunder in any
such case if and only to the extent that any such loss, claim,
damage or liability arises out of or is based upon an untrue
statement or alleged untrue statement or omission or alleged
omission made in reliance upon and based upon information
pertaining to the Stockholders, furnished by or for the
Stockholders in writing.

          (c)  Promptly after receipt by an indemnified party
hereunder of notice of the commencement of any action, such
indemnified party shall, if a claim in respect thereof is to be
made against the indemnifying party hereunder, notify the
indemnifying party in writing thereof, but the omission so to
notify the indemnifying party shall not relieve it from any
liability which it may have to such indemnified party other than
under this Section 10 and shall only relieve it from any
liability which it may have to such indemnified party under this
Section 10 if and to the extent the indemnifying party is
prejudiced by such omission.  In case any such action shall be
brought against any indemnified party and it shall notify the
indemnifying party of the commencement thereof, the indemnifying
party shall be entitled to participate in and, to the extent it
shall wish, to assume and undertake the defense thereof with
counsel satisfactory to such indemnified party, and, after notice
from the indemnifying party to such indemnified party of its
election so to assume and undertake the defense thereof and the
approval by the indemnified party of the counsel chosen by the
indemnifying party, the indemnifying party shall not be liable to
such indemnified party under this Section 10 for any legal
expenses subsequently incurred by such indemnified party in
connection with the defense thereof other than reasonable costs
of investigation and of liaison with counsel so selected,
provided, however, that, if the defendants in any such action
include both the indemnified party and the indemnifying party and
if the interests of the indemnified party reasonably may be
deemed to conflict with the interests of the indemnifying party,
the indemnified party shall have the right to select a separate
counsel and to assume such legal defenses and otherwise to
participate in the defense of such action, with the expenses and
fees of such separate counsel and other expenses related to such
participation to be reimbursed by the indemnifying party as
incurred.

          (d)  In order to provide for just and equitable
contribution to joint liability in any case in which either (i) a
Stockholder exercises rights under this Agreement and makes a
claim for indemnification pursuant to this Section 10 but it is
judicially determined (by the entry of a final judgment or decree
by a court of competent jurisdiction and the expiration of time
to appeal or the denial of the last right of appeal) that such
indemnification may not be enforced in such case notwithstanding
the fact that this Section 10 provides for indemnification in
such case, or (ii) contribution under the Securities Act may be
required on the part of the Stockholder in circumstances for
which indemnification is provided under this Section 10; then,
and in each such case, the Company and the Stockholders will
contribute to the aggregate losses, claims, damages or
liabilities to which they may be subject (after contribution from
others) in proportion to the relative fault of the Company, on
the one hand, and the Stockholders, on the other hand; provided,
however, that, in any such case, no person or entity guilty of
fraudulent misrepresentation (within the meaning of Section 10(f)
of the Securities Act) will be entitled to contribution from any
person or entity who was not guilty of such fraudulent
misrepresentation.

          (e)  The indemnities provided in this Section 10 shall
survive the transfer of any Shares by the Stockholder.

     11.  Reports Under Securities Exchange Act of 1934.  With a
view to making available to each of the Stockholders the benefits
of Rule 144 promulgated under the Securities Act and any other
rule or regulation thereunder that may at any time permit any
such Stockholder to sell securities of the Company to the public
without registration, the Company agrees to:

          (a)  make and keep public information available, as
those terms are understood and defined in Rule 144;

          (b)  maintain registration of its Common Stock under
Section 12 of the Exchange Act;

          (c)  file in a timely manner all reports and other
documents required of the Company under the Securities Act and
the Exchange Act; and

          (d)  furnish to any such Stockholder, so long as the
Stockholder owns any Shares, forthwith upon request:  (i) a
written statement by the Company that it has complied with the
reporting requirements of Rule 144, (ii) a copy of the most
recent annual or quarterly report of the Company and such other
reports and documents so filed by the Company; and (iii) such
other information as may be reasonably requested in availing the
Stockholder of any rule or regulation under the Securities Act
which permits the selling of any such securities without
registration or pursuant to such form.

     12.  Changes in Common Stock.  If, and as often as, there is
any change in the Common Stock by way of a stock split, stock
dividend, combination or reclassification, or through a merger,
consolidation, reorganization or recapitalization, or by any
other means, appropriate adjustment shall be made in the
provisions hereof so that the rights and privileges granted
hereby shall continue with respect to the Shares as so changed.

     13.  Stockholder's Conduct.  With respect to any sale of
Shares covered by a registration statement, each Stockholder
understands and agrees as follows:

          (a)  Each Stockholder will carefully review the
information concerning him contained in any registration
statement and will promptly notify the Company if such
information is not complete and accurate in all respects,
including having properly disclosed any position, office or other
material relationship within the past three years with the
Company or its affiliates;

          (b)  Each Stockholder agrees to sell Shares only in the
manner set forth in (i) the applicable registration statement
(or in compliance with Section 5 hereof), (ii) the Affiliate
Agreement (as defined in the Merger Agreement) and (iii) Section
14;

          (c)  Each Stockholder agrees to comply with the anti-
manipulation rules under the Exchange Act in connection with
purchases and sales of securities of the Company during the time
any registration statement remains effective;

          (d)  Each Stockholder agrees to only sell Shares in a
jurisdiction after counsel for the Company has advised that such
sale is permissible under the applicable state securities or
"Blue Sky" laws;

          (e)  Each Stockholder agrees to comply with the
prospectus delivery requirements of the Securities Act;

          (f)  Each Stockholder agrees to promptly notify the
Company of any and all planned sales and completed sales of
Shares; and

          (g)  Each Stockholder agrees to suspend sales during
the periods when sales are to be suspended pursuant to Section 8.

          (h)  In connection with the registration of the Shares,
each Stockholder will furnish to the Company in writing such
information requested by the Company with respect to himself and
the proposed distribution by him as shall be necessary in order
to  comply with federal and applicable state securities laws.

          (i)  Each Stockholder hereby agrees that he will not
sell, exchange, transfer, pledge, dispose or otherwise reduce his
risk relative to any Shares owned by him during the period which
begins on the date hereof and ends at such time as the Company
publicly announces financial results covering at least thirty
days of combined operations of the Company and KMI.  The Company,
at its discretion, may cause stop transfer orders to be placed
with its transfer agent with respect to the certificates
representing the Shares, provided that such stop transfer orders
are consistent with the other provisions of this Agreement.

     14.  Selling Procedures.

          (a)  Each Stockholder will notify the Company of his
intention to sell Shares under any registration statement not
less than five (5) business days prior to the expected date of
such sale by faxing the "Takedown Request" attached hereto as
Exhibit A to:

                 Testa, Hurwitz & Thibeault, LLP
                         125 High Street
                        High Street Tower

                   Facsimile:  (617) 248-7100

During this period, the Company will review the prospectus to
determine if a suspension pursuant to Section 8 is necessary or
appropriate.  If the Company does not notify the Stockholder of a
suspension pursuant to Section 8, the Stockholder may conclude
the proposed sale, on the proposed date of sale, strictly in
accordance with the Takedown Request.

          (b)  Each Stockholder will notify the Company of each
sale under any registration statement in accordance with the
Takedown Request within 24 hours of the sale by faxing the
"Notification of Sale" attached hereto as Exhibit B to:

                 Testa, Hurwitz & Thibeault, LLP
                         125 High Street
                        High Street Tower
                  Boston, Massachusetts  02110

                     Phone:  (617) 248-7278
                   Facsimile:  (617) 248-7100

Based on the information set forth on the Notification of Sale,
the Company will prepare or cause to be prepared the appropriate
notifications to its Transfer Agent to remove the legend
described in Section 4 from the Shares so sold.

     15.  Representations and Covenants.  Each Stockholder hereby
represents and warrants to the Company as follows:

          (a)  THE STOCKHOLDER UNDERSTANDS THAT HIS INVESTMENT IN
THE SHARES INVOLVES RISK.

          (b)  THE STOCKHOLDER HAS CONSULTED HIS OWN ATTORNEY(S),
ACCOUNTANT(S) OR INVESTMENT ADVISOR(S) WITH RESPECT TO THE
INVESTMENT CONTEMPLATED HEREBY AND ITS SUITABILITY FOR THE
STOCKHOLDER.  ANY SPECIFIC ACKNOWLEDGMENT SET FORTH BELOW WITH
RESPECT TO ANY STATEMENT OR INFORMATION FURNISHED TO THE
STOCKHOLDER SHALL NOT BE DEEMED TO LIMIT THE GENERALITY OF THIS
REPRESENTATION AND WARRANTY.

          (c)  The Stockholder understands that he must bear the
economic risk of this investment until such time as the Shares
are registered; that the Shares are not currently registered
under the Securities Act, and, therefore, cannot be resold unless
they are subsequently registered under the Securities Act or
unless an exemption from such registration is available; that the
Stockholder is purchasing the Shares with no present view toward
resale or other distribution thereof; and that the Stockholder
agrees not to resell or otherwise dispose of all or any part of
the Shares, except as permitted by law, including, without
limitation, any and all applicable provisions of the Merger
Agreement and this Agreement and any regulations under the
Securities Act and applicable state securities laws.

          (d)  The Stockholder has adequate means of providing
for his current needs and personal contingencies and has no need
for liquidity in connection with this investment in the Shares.

          (e)  The Stockholder has reviewed the representations
and warranties of the Company set forth in the Merger Agreement,
as well as the information provided to the Stockholder by the
Company pursuant to Section 5.05 of the Merger Agreement and has
consulted with his personal legal and financial advisors in
evaluating the merits and risks of the investment in the Shares.

          (f)  The Stockholder received an offer concerning the
Shares and first learned of this investment in the state or other
jurisdiction listed in the Stockholder's residence address on the
signature page hereto, and intends that the state securities laws

                  REGISTRATION RIGHTS AGREEMENT

   AGREEMENT dated as of December 1, 1997 among PAREXEL
International Corporation, a Massachusetts corporation (the
"Company") and Clarence A. Kemper, P. Michael Masterson, Mark A.
Lester, Ronald Tetzlaff, Alan R. Parenteau, Warren Handren, David
Hyde and Jon R. Voss (individually, a "Stockholder," and
collectively, the "Stockholders").

                      W I T N E S S E T H :

   WHEREAS, pursuant to the Agreement and Plan of Reorganization
and Merger dated as of October 22, 1997 (the "Merger Agreement")
among the Company, KMI Acquisition Corporation, a Massachusetts
corporation ("Sub"),  Kemper-Masterson, Inc., a Delaware
corporation ("KMI") and the other parties named therein, Sub will
be merged with and into KMI and KMI will become a wholly-owned
subsidiary of the Company;

   WHEREAS, in connection therewith, the Stockholders will
receive unregistered shares of Common Stock of the Company (the
"Shares"); and

   WHEREAS, the Company and the Stockholders wish to set forth
certain rights and obligations with regard to the registration of
the Shares;

   NOW, THEREFORE, the parties hereto agree as follows:

     1.   Certain Definitions.  As used in this Agreement, the
following terms shall have the following respective meanings:

        "Commission" shall mean the Securities and Exchange
   Commission, or any other federal agency at the time
   administering the Securities Act.

        "Shares" shall mean the shares of Common Stock of the
   Company issued to the Stockholders on even date herewith
   pursuant to the Merger Agreement.

        "Common Stock" shall mean the Common Stock, $.01 par
   value, of the Company, as constituted as of the date of this
   Agreement.

        "Exchange Act" shall mean the Securities Exchange Act of
   1934, as amended, or any successor federal statute, and the
   rules and regulations of the Commission thereunder, all as
   the same shall be in effect at the time.

        "Registration Expenses" shall mean the expenses so
   described in Section 9.

        "Securities Act" shall mean the Securities Act of 1933,
   as amended, or any successor federal statute, and the rules
   and regulations of the Commission thereunder, all as the same
   shall be in effect at the time.

        "Selling Expenses" shall mean the expenses so described
   in Section 9.

     2.   Compliance with Securities Laws.  The Stockholders
represent and warrant that they:

          (a)  have paid no brokerage or similar commissions in
connection with the acquisition of the Shares.

          (b)  are acquiring such Shares solely for their own
account.

          (c)  have provided such information as may reasonably
have been requested by the Company in order for the Company or
its counsel to evaluate the availability of an exemption under
the Securities Act for the issuance of the Shares to the
Stockholders.

     3.   Securities Act Matters.  The Stockholders acknowledge
and agree that the Shares have not been registered under the
Securities Act or under the securities laws of any state, in
reliance upon certain exemptive provisions of such statutes.  The
Stockholders recognize and acknowledge that such claims of
exemption are based, in part, upon the Stockholders'
representations contained in this Agreement.  The Stockholders
further recognize and acknowledge that, because the Shares are
unregistered under federal and state laws, they are not presently
eligible for public resale, and may only be resold in the future
pursuant to an effective registration statement under the
Securities Act and any applicable state securities laws, or
pursuant to a valid exemption from such registration
requirements.  The Stockholders recognize and acknowledge that
Rule 144 (which facilitates routine sales of securities in
accordance with the terms and conditions of that Rule, including
a holding period requirement) is not now available for resale of
the Shares, and the Stockholders recognize and acknowledge that,
in the absence of the availability of Rule 144, a sale pursuant
to a claim of exemption from registration under the Securities
Act would require compliance with some other exemption under the
Securities Act, which may not be available for resale of the
Shares.  The Stockholders recognize and acknowledge that, except
as set forth in this Agreement, the Company is under no
obligation to register the Shares, either pursuant to the
Securities Act or the securities laws of any state.

     4.   Restrictive Legend.  Each certificate representing
Shares shall, except as otherwise provided in this Section 4 or
in Section 5, be stamped or otherwise imprinted with a legend
substantially in the following form:

          "The Securities represented hereby have not been
     registered under the Securities Act of 1933, as
     amended, and may not be sold, transferred or otherwise
     disposed of except in accordance with the terms thereof
     and unless registered with the Securities and Exchange
     Commission of the United States and the securities
     regulatory authorities of certain states or unless an
     exemption from such registration is available."

     Such certificates shall not bear such legend if in the
opinion of counsel satisfactory to the Company the securities
being sold thereby may be publicly sold without registration
under the Securities Act or if such securities have been sold
pursuant to Rule 144, any other exemption under the Securities
Act or an effective registration statement.

     5.   Notice of Proposed Transfer.  Prior to any proposed
transfer of any Shares before the expiration of the applicable
holding period set forth in Rule 144, each Stockholder shall give
written notice to the Company of his intention to effect such
transfer.  Prior to any registration statement described in
Section 6 becoming effective, each such notice shall describe the
manner of the proposed transfer and, if requested by the Company,
shall be accompanied by an opinion of counsel satisfactory to the
Company to the effect that the proposed transfer may be effected
without registration under the Securities Act, whereupon the
Stockholder shall be entitled to transfer such security in
accordance with the terms of his notice.  Each certificate for
Shares transferred as above provided shall bear the legend set
forth in Section 4, except that such certificate shall not bear
such legend if (i) such transfer is in accordance with the
provisions of Rule 144 (or any other rule permitting public sale
without registration under the Securities Act), (ii) such
transfer is pursuant to a registration under the Securities Act,
or (iii) the opinion of counsel referred to above is to the
further effect that the transferee and any subsequent transferee
(other than an affiliate of the Company) would be entitled to
transfer such securities in a public sale without registration
under the Securities Act.

     6.   Required Registration.  The Company agrees to use
commercially reasonable efforts to (i) cause a registration
statement on Form S-3 (the "Initial Registration Statement") or
any successor form thereto under the Securities Act relating to
the resale of fifty percent (50%) of the Shares to be filed no
later than the 90th day following the date of the Merger
Agreement; (ii) cause a registration statement on Form S-3 or any
successor form thereto under the Securities Act (or an amendment
to the Initial Registration Statement) relating to the resale of
the remaining fifty percent (50%) of the Shares (including all of
the Holdback Shares) to be filed approximately 180 days after the
filing date of the Initial Registration Statement; and (iii)
cause the Initial Registration Statement to become effective as
soon as practicable after the filing of the Initial Registration
Statement and thereafter remain effective until the earlier of
(A) one year after the date of the Merger Agreement or (B) the
sale of all Shares covered thereby.  Anything to the contrary
herein notwithstanding, the Company shall not be required to take
any action to cause any registration statement to be declared
effective by the Commission at any time prior to the publication
by the Company of financial results including at least thirty
(30) days' post-closing combined operating results of the Company
and KMI (the "Pooling Restricted Period"), and the Company may
suspend sales in accordance with Section 8 at any time under any
registration statement immediately upon written notice to the
Stockholders at their last known address, for any of the reasons
and for the time periods set forth in Section 8.

     7.   Registration Procedures.  If and whenever the Company
is required by the provisions of Section 6 to use commercially
reasonable efforts to effect the registration of any Shares under
the Securities Act, the Company will, as expeditiously as
possible:

          (a)  prepare and file with the Commission such
amendments and supplements to the applicable registration
statement, and the prospectus used in connection therewith, as
may be necessary to comply with the Securities Act;

          (b)  furnish to the Stockholders such number of copies
of the relevant registration statement and each amendment and
supplement thereto (in each case including exhibits) and the
prospectus included therein (including each preliminary
prospectus) as they reasonably may request in order to facilitate
the public sale or other disposition of the Shares covered by
such registration statement;

          (c)  register or qualify the Shares covered by the
applicable registration statement under the securities or "blue
sky" laws of the jurisdictions where the Company is currently
registered or qualified, provided, however, that the Company
shall not for any such purpose be required to qualify generally
to transact business as a foreign corporation in any jurisdiction
where it is not so qualified or to consent to general service of
process in any such jurisdiction;

          (d)  have the Shares covered by the applicable
registration statement subject to quotation on the Nasdaq
National Market; and

          (e)  promptly notify each Stockholder (at his last
known address) (i) of the effective date of the applicable
registration statement and the date when any post-effective
amendment to such registration statement becomes effective, (ii)
of any stop order or notification from the Commission or any
other jurisdiction as to the suspension of the effectiveness of
such registration statement, or (iii) of the institution and
ending of any suspension under Section 8.

     8.   Suspension.

          (a)  The rights of the Stockholders to resell the
Shares pursuant to this Agreement and the applicable registration
statement may be suspended by the Company on the occurrence of
any of the following events:

               (i)  the Company has made a determination to
     conduct a public offering;
               (ii) the Company is about to make a public
     disclosure of information of a material nature;
     
               (iii)     there then exists material, non-public
     information relating to the Company which, in the good faith
     determination of its Board of Directors, the disclosure of
     which would not be in the interests of the Company or its
     stockholders during that time; or
     
               (iv) the Company is engaged in any activity at any
     time that, in the good faith determination of its Board of
     Directors, would be adversely affected by the continued
     compliance with this Agreement or the continued distribution
     of the Shares by the Stockholders.

          (b)  The Company shall use commercially reasonable
efforts to minimize the length of any suspension:

               (i) under Section 8(a)(i), to a period of thirty
(30) days, beginning on the day that notice of a suspension is
given to the Stockholders and ending on the earlier of:  (A) the
date of disclosure of the public offering, or (B) the date which
is 30 days after the beginning of the suspension, provided that
during such suspension, the Company will proceed with
commercially reasonable efforts to file the appropriate
documentation in respect of, and otherwise complete, such public
offering as expeditiously as practicable;

               (ii) under Section 8(a)(ii), to a period of three
(3) business days;

               (iii)     under Section 8(a)(iii) or 8(a)(iv), if
the activity is a prospective acquisition by the Company, to a
period beginning when the notice of suspension is given to the
Stockholders and ending on the earliest of:  (A) the date on
which the Company publicly announces the acquisition, (B) the
closing of the transaction and the making of all required filings
under the Securities Act or Exchange Act, or (C) the date on
which discussions regarding the acquisition are terminated; and

               (iv) under Section 8(a)(iii) or 8(a)(iv), for any
reason other than a prospective acquisition by the Company, to a
period beginning when the notice of suspension is given to the
Stockholders and ending on the earlier of:  (A) the disclosure of
the activity, or (B) the reason is no longer operative (provided,
however, that the Company shall not avail itself of the
suspension rights contained in Section 8(a)(iv) more than once in
every six (6) month period commencing on the date of
effectiveness of the Registration Statement).

     9.   Expenses.  All expenses incurred by the Company in
complying with Section 6, including, without limitation, all
registration and filing fees, printing expenses, fees and
disbursements of counsel and independent public accountants for
the Company, fees and expenses incurred in connection with
complying with state securities or "blue sky" laws, fees of the
National Association of Securities Dealers, Inc., transfer taxes,
fees of transfer agents and registrars, and costs of issuance,
but excluding any Selling Expenses, are called "Registration
Expenses".  All underwriting discounts (if any) and selling
commissions applicable to the sale of the Shares covered by any
registration statement, as well as all professional service fees
incurred by the Stockholders, are called "Selling Expenses".

     All Selling Expenses shall be borne by the Stockholders.
The Company will pay all Registration Expenses in connection with
the preparation and filing of each registration statement.  The
Company shall not be obligated to pay any Registration Expenses
in connection with the preparation and filing of any registration
statement if such registration statement is withdrawn, delayed or
abandoned for any reason by the Stockholders.

     10.  Indemnification and Contribution.

          (a)  In connection with the registration of the Shares
under the Securities Act pursuant to Section 6, the Company will
indemnify and hold harmless each Stockholder, each underwriter of
such Shares thereunder and each other person, if any, who
controls such underwriter within the meaning of the Securities
Act, against any losses, claims, damages or liabilities, joint or
several, to which such Stockholder, underwriter or controlling
person may become subject under the Securities Act, Exchange Act,
state securities laws or otherwise, insofar as such losses,
claims, damages or liabilities (or actions in respect thereof)
arise out of or are based upon (i) any untrue statement or
alleged untrue statement of material fact contained in the
registration statement under which such Shares were registered
under the Securities Act pursuant to Section 6, any preliminary
prospectus or final prospectus contained therein, or any
amendment or supplement thereto, (ii) the omission or alleged
omission of a material fact required to be stated therein or
necessary to make the statements therein not misleading or
(iii) any violation by the Company or its agents of any rule or
regulation promulgated under the Securities Act, Exchange Act or
state securities laws applicable to the Company or its agents and
relating to action or inaction required of the Company in
connection with such registration, and the Company will reimburse
each such Stockholder, each such underwriter and each such
controlling person for any legal or other expenses reasonably
incurred by them in connection with investigating or defending
any such loss, claim, damage, liability or action, as such
expenses are incurred, provided, however, that the Company will
not be liable in any such case if and to the extent that any such
loss, claim, damage or liability arises out of or is based upon
an untrue statement or alleged untrue statement or omission or
alleged omission so made based upon information furnished by any
such Stockholder, any such underwriter or any such controlling
person.

          (b)  In connection with the registration of the Shares
under the Securities Act pursuant to Section 6, the Stockholders
will indemnify and hold harmless the Company, each person, if
any, who controls the Company within the meaning of the
Securities Act, each officer of the Company who signs such
registration statement, each director of the Company, each
underwriter and each person who controls any underwriter within
the meaning of the Securities Act, against all losses, claims,
damages or liabilities, joint or several, to which the Company or
such officer, director, underwriter or controlling person may
become subject under the Securities Act or otherwise, insofar as
such losses, claims, damages or liabilities (or actions in
respect thereof) arise out of or are based upon (i) the failure
of the Stockholders to comply with the provisions of Section 13
herein or (ii) any untrue statement or alleged untrue statement
of any material fact contained in the registration statement, any
preliminary prospectus or final prospectus contained therein, or
any amendment or supplement thereto, or (iii) the omission or
alleged omission to state therein a material fact required to be
stated therein or necessary to make the statements therein not
misleading, and will reimburse the Company and each such officer,
director, underwriter and controlling person for any legal or
other expenses reasonably incurred by them in connection with
investigating or defending any such loss, claim, damage,
liability or action, as such expenses are incurred, provided,
however, that the Stockholders will be liable hereunder in any
such case if and only to the extent that any such loss, claim,
damage or liability arises out of or is based upon an untrue
statement or alleged untrue statement or omission or alleged
omission made in reliance upon and based upon information
pertaining to the Stockholders, furnished by or for the
Stockholders in writing.

          (c)  Promptly after receipt by an indemnified party
hereunder of notice of the commencement of any action, such
indemnified party shall, if a claim in respect thereof is to be
made against the indemnifying party hereunder, notify the
indemnifying party in writing thereof, but the omission so to
notify the indemnifying party shall not relieve it from any
liability which it may have to such indemnified party other than
under this Section 10 and shall only relieve it from any
liability which it may have to such indemnified party under this
Section 10 if and to the extent the indemnifying party is
prejudiced by such omission.  In case any such action shall be
brought against any indemnified party and it shall notify the
indemnifying party of the commencement thereof, the indemnifying
party shall be entitled to participate in and, to the extent it
shall wish, to assume and undertake the defense thereof with
counsel satisfactory to such indemnified party, and, after notice
from the indemnifying party to such indemnified party of its
election so to assume and undertake the defense thereof and the
approval by the indemnified party of the counsel chosen by the
indemnifying party, the indemnifying party shall not be liable to
such indemnified party under this Section 10 for any legal
expenses subsequently incurred by such indemnified party in
connection with the defense thereof other than reasonable costs
of investigation and of liaison with counsel so selected,
provided, however, that, if the defendants in any such action
include both the indemnified party and the indemnifying party and
if the interests of the indemnified party reasonably may be
deemed to conflict with the interests of the indemnifying party,
the indemnified party shall have the right to select a separate
counsel and to assume such legal defenses and otherwise to
participate in the defense of such action, with the expenses and
fees of such separate counsel and other expenses related to such
participation to be reimbursed by the indemnifying party as
incurred.

          (d)  In order to provide for just and equitable
contribution to joint liability in any case in which either (i) a
Stockholder exercises rights under this Agreement and makes a
claim for indemnification pursuant to this Section 10 but it is
judicially determined (by the entry of a final judgment or decree
by a court of competent jurisdiction and the expiration of time
to appeal or the denial of the last right of appeal) that such
indemnification may not be enforced in such case notwithstanding
the fact that this Section 10 provides for indemnification in
such case, or (ii) contribution under the Securities Act may be
required on the part of the Stockholder in circumstances for
which indemnification is provided under this Section 10; then,
and in each such case, the Company and the Stockholders will
contribute to the aggregate losses, claims, damages or
liabilities to which they may be subject (after contribution from
others) in proportion to the relative fault of the Company, on
the one hand, and the Stockholders, on the other hand; provided,
however, that, in any such case, no person or entity guilty of
fraudulent misrepresentation (within the meaning of Section 10(f)
of the Securities Act) will be entitled to contribution from any
person or entity who was not guilty of such fraudulent
misrepresentation.

          (e)  The indemnities provided in this Section 10 shall
survive the transfer of any Shares by the Stockholder.

     11.  Reports Under Securities Exchange Act of 1934.  With a
view to making available to each of the Stockholders the benefits
of Rule 144 promulgated under the Securities Act and any other
rule or regulation thereunder that may at any time permit any
such Stockholder to sell securities of the Company to the public
without registration, the Company agrees to:

          (a)  make and keep public information available, as
those terms are understood and defined in Rule 144;

          (b)  maintain registration of its Common Stock under
Section 12 of the Exchange Act;

          (c)  file in a timely manner all reports and other
documents required of the Company under the Securities Act and
the Exchange Act; and

          (d)  furnish to any such Stockholder, so long as the
Stockholder owns any Shares, forthwith upon request:  (i) a
written statement by the Company that it has complied with the
reporting requirements of Rule 144, (ii) a copy of the most
recent annual or quarterly report of the Company and such other
reports and documents so filed by the Company; and (iii) such
other information as may be reasonably requested in availing the
Stockholder of any rule or regulation under the Securities Act
which permits the selling of any such securities without
registration or pursuant to such form.

     12.  Changes in Common Stock.  If, and as often as, there is
any change in the Common Stock by way of a stock split, stock
dividend, combination or reclassification, or through a merger,
consolidation, reorganization or recapitalization, or by any
other means, appropriate adjustment shall be made in the
provisions hereof so that the rights and privileges granted
hereby shall continue with respect to the Shares as so changed.

     13.  Stockholder's Conduct.  With respect to any sale of
Shares covered by a registration statement, each Stockholder
understands and agrees as follows:

          (a)  Each Stockholder will carefully review the
information concerning him contained in any registration
statement and will promptly notify the Company if such
information is not complete and accurate in all respects,
including having properly disclosed any position, office or other
material relationship within the past three years with the
Company or its affiliates;

          (b)  Each Stockholder agrees to sell Shares only in the
manner set forth in (i) the applicable registration statement
(or in compliance with Section 5 hereof), (ii) the Affiliate
Agreement (as defined in the Merger Agreement) and (iii) Section
14;

          (c)  Each Stockholder agrees to comply with the anti-
manipulation rules under the Exchange Act in connection with
purchases and sales of securities of the Company during the time
any registration statement remains effective;

          (d)  Each Stockholder agrees to only sell Shares in a
jurisdiction after counsel for the Company has advised that such
sale is permissible under the applicable state securities or
"Blue Sky" laws;

          (e)  Each Stockholder agrees to comply with the
prospectus delivery requirements of the Securities Act;

          (f)  Each Stockholder agrees to promptly notify the
Company of any and all planned sales and completed sales of
Shares; and

          (g)  Each Stockholder agrees to suspend sales during
the periods when sales are to be suspended pursuant to Section 8.

          (h)  In connection with the registration of the Shares,
each Stockholder will furnish to the Company in writing such
information requested by the Company with respect to himself and
the proposed distribution by him as shall be necessary in order
to  comply with federal and applicable state securities laws.

          (i)  Each Stockholder hereby agrees that he will not
sell, exchange, transfer, pledge, dispose or otherwise reduce his
risk relative to any Shares owned by him during the period which
begins on the date hereof and ends at such time as the Company
publicly announces financial results covering at least thirty
days of combined operations of the Company and KMI.  The Company,
at its discretion, may cause stop transfer orders to be placed
with its transfer agent with respect to the certificates
representing the Shares, provided that such stop transfer orders
are consistent with the other provisions of this Agreement.

     14.  Selling Procedures.

          (a)  Each Stockholder will notify the Company of his
intention to sell Shares under any registration statement not
less than five (5) business days prior to the expected date of
such sale by faxing the "Takedown Request" attached hereto as
Exhibit A to:

                 Testa, Hurwitz & Thibeault, LLP
                         125 High Street
                        High Street Tower
                  Boston, Massachusetts  02110
                 Attn:  William J. Schnoor, Jr.
                     Phone:  (617) 248-7278
                   Facsimile:  (617) 248-7100

During this period, the Company will review the prospectus to
determine if a suspension pursuant to Section 8 is necessary or
appropriate.  If the Company does not notify the Stockholder of a
suspension pursuant to Section 8, the Stockholder may conclude
the proposed sale, on the proposed date of sale, strictly in
accordance with the Takedown Request.

          (b)  Each Stockholder will notify the Company of each
sale under any registration statement in accordance with the
Takedown Request within 24 hours of the sale by faxing the
"Notification of Sale" attached hereto as Exhibit B to:

                 Testa, Hurwitz & Thibeault, LLP
                         125 High Street
                        High Street Tower
                  Boston, Massachusetts  02110

                     Phone:  (617) 248-7278
                   Facsimile:  (617) 248-7100

Based on the information set forth on the Notification of Sale,
the Company will prepare or cause to be prepared the appropriate
notifications to its Transfer Agent to remove the legend
described in Section 4 from the Shares so sold.

     15.  Representations and Covenants.  Each Stockholder hereby

          (a)  THE STOCKHOLDER UNDERSTANDS THAT HIS INVESTMENT IN
THE SHARES INVOLVES RISK.

STOCKHOLDER SHALL NOT BE DEEMED TO LIMIT THE GENERALITY OF THIS
REPRESENTATION AND WARRANTY.

          (c)  The Stockholder understands that he must bear the
economic risk of this investment until such time as the Shares
are registered; that the Shares are not currently registered
under the Securities Act, and, therefore, cannot be resold unless
they are subsequently registered under the Securities Act or
unless an exemption from such registration is available; that the
Stockholder is purchasing the Shares with no present view toward
resale or other distribution thereof; and that the Stockholder
agrees not to resell or otherwise dispose of all or any part of
the Shares, except as permitted by law, including, without
limitation, any and all applicable provisions of the Merger
Agreement and this Agreement and any regulations under the
Securities Act and applicable state securities laws.

for his current needs and personal contingencies and has no need
for liquidity in connection with this investment in the Shares.

          (e)  The Stockholder has reviewed the representations
and warranties of the Company set forth in the Merger Agreement,
as well as the information provided to the Stockholder by the
Company pursuant to Section 5.05 of the Merger Agreement and has
consulted with his personal legal and financial advisors in
evaluating the merits and risks of the investment in the Shares.

          (f)  The Stockholder received an offer concerning the
Shares and first learned of this investment in the state or other
jurisdiction listed in the Stockholder's residence address on the
signature page hereto, and intends that the state securities laws
of that state or other jurisdiction alone govern this
transaction.

          (g)  The Stockholder hereby acknowledges receipt of the
documents described in Section 5.05 of the Merger Agreement,
which documents each Stockholder has reviewed.  The Stockholder
further acknowledges and warrants that, prior to the execution of
this Agreement, he has had the opportunity to ask questions and
receive answers from the Company and KMI concerning the terms and
conditions of the transactions contemplated by the Merger
Agreement and the issuance of the Shares, and concerning any of
the documents identified above, and to obtain such additional
further information from the Company and KMI as he has deemed
necessary to verify the accuracy of the information contained in
the documents identified above or any other information furnished
to the Stockholder.

          (h)  The Stockholder has been advised that, as of the
date hereof, he may be deemed to be an "affiliate" of KMI, as the
term "affiliate" is used in and for purposes of Accounting Series
Releases 130 and 135, as amended, of the Commission.

          (i)  The Stockholder understands that the
representations, warranties and covenants set forth herein will
be relied upon by KMI, the Company, the stockholders of the
Company and their respective counsel and accounting firms.

          (j)  The Stockholder hereby represents and warrants
that he has not sold, exchanged, transferred, pledged, disposed
or otherwise reduced his risk relative to any shares of KMI
common stock owned by him during the 30 day period preceding the

     16.  Miscellaneous.

          (a)  All covenants and agreements contained in this
Agreement by or on behalf of any of the parties hereto shall bind

   (viii) all of Seller's rights, claims, credits, causes of

     (ix) all of Seller's Proprietary Rights owned, licensed or

   (xiii) all goodwill associated with the Business or the
   Purchased Assets, together with the right to represent to

       2.02.  Excluded Assets.  Buyer expressly understands and
agrees that Buyer is acquiring substantially all of the assets of
Seller and that the following assets and properties of Seller
(the "Excluded Assets") shall be excluded from the Purchased
Assets:

      (i) rights under those contracts, agreements and
   commitments listed on Schedule 2.02 and under this Agreement;

     (ii) the right of Seller and Foster to receive the purchase
   price; and

    (iii) any Purchased Assets sold or otherwise disposed of in
   the ordinary course of the operation of the Business and not
   in violation of any provisions of this Agreement during the
   period from the date hereof until the Closing Date.

       2.03.  Assumption of Liabilities.  Upon the terms and
subject to the conditions of this Agreement, Buyer agrees,
effective at the time of Closing, to assume the following
liabilities (the "Assumed Liabilities"):

      (i) all operating liabilities accrued on the Balance
   Sheet; and

     (ii) all liabilities arising out of or relating primarily
   to the Business, and incurred in the ordinary course of
   Business since the Balance Sheet Date, but only to the extent
   listed on Schedule 2.03;

    (iii) all liabilities and obligations of Seller arising
   under the Contracts (other than liabilities or obligations
   attributable to any failure by Seller to comply with the
   terms thereof);

     (iv) all obligations of Seller and Foster under that
   certain Vectra Bank Building Lease by and among the Colorado
   Building Group, Seller and Foster dated as of September 23,
   1994 and extended by that certain letter agreement dated
   September 27, 1996;

   provided, however, that the foregoing Assumed Liabilities
   shall be in the aggregate no greater than $5,000.

       2.04.  Excluded Liabilities.  Notwithstanding any
provision in this Agreement or any other writing to the contrary,
Buyer is assuming only the Assumed Liabilities and is not
assuming any other liability or obligation of Seller or Foster or
any Affiliate of Seller (or any predecessor owner of all or part
of its business and assets) of whatever nature whether presently
in existence or arising or asserted hereafter.  All such other
liabilities and obligations shall be retained by and remain
obligations and liabilities of Seller or its Affiliate (all such
liabilities and obligations not being assumed being herein
referred to as the "Excluded Liabilities").  Without limiting the
foregoing, none of the following shall be Assumed Liabilities for
the purposes of this Agreement:

      (i) except to the extent of the specific reserves on the
   Balance Sheet, any obligation or liability for Tax arising
   from or with respect to the Purchased Assets or the operation
   of the Business which is incurred in or attributable to any
   Pre-Closing Tax Period;

     (ii) except to the extent provided in Article IX, any
   liabilities or obligations relating to employee benefits or
   compensation arrangements existing as of the end of the day
   on the day preceding the Closing Date, including, without
   limitation, any liabilities or obligations under any of
   Seller's employee benefit agreements, plans or other
   arrangements listed on Schedule 9.01;

    (iii) any liability or obligation for damages (whether based
   on negligence, breach of warranty, strict liability or any
   other theory) caused by or arising out of or resulting from,
   directly or indirectly, the sale by Seller or its Affiliates
   of any products or services prior to the Closing Date;

     (iv) all liabilities and obligations relating to any claim,
   dispute or litigation asserted or threatened or governmental
   proceeding or investigation instituted or threatened, arising
   out of, or in connection with, any alleged violation or
   noncompliance by Seller of, or failure to perform any
   obligations imposed upon Seller in its conduct of the
   Business under any statute, rule, regulation or ordinance
   pertaining to protection of the environment (including any
   Environmental Law), employee or occupational safety and
   health, wage and hour, Hazardous Substances, civil rights,
   customs and export control and zoning, which alleged
   violation, noncompliance or failure to perform occurred or
   existed on or prior to the Closing Date, but only to the
   extent of such pre-existing violation, noncompliance or
   failure to perform;

      (v) all liabilities and obligations relating to any
   products manufactured or sold by the Business on or prior to
   the Closing Date, including without limitation warranty
   obligations and product liability claims;

     (vi) any Environmental Liability;

    (vii) any liability or obligation relating to an Excluded
   Asset; and

   (viii) Assumed Liabilities which in the aggregate exceed
   $5,000, as permitted by Section 2.03.

       2.05.  Assignment of Contracts and Rights.
Notwithstanding, anything in this Agreement to the contrary, this
Agreement shall not constitute an agreement to assign any
Purchased Asset or any claim or right or any benefit arising
thereunder or resulting therefrom if an attempted assignment
thereof, without consent of a third party thereto, would
constitute a breach or other contravention thereof or in any way
adversely affect the rights of Buyer or Seller thereunder.
Seller and Foster agree to use their commercially reasonable best
efforts (but without any payment of money by Seller or Buyer) to
obtain the consent of the other parties to any such Purchased
Asset or claim or right or any benefit arising thereunder for the
assignment thereof to Buyer as Buyer may reasonably request.  If
such consent is not obtained, or if an attempted assignment
thereof would be ineffective or would adversely affect the rights
of Seller thereunder so that Buyer would not in fact receive all
such rights, Seller and Buyer will cooperate in a mutually
agreeable arrangement under which Buyer would obtain the benefits
and assume the obligations thereunder in accordance with this
Agreement, including subcontracting, sub-licensing, or subleasing
to Buyer, or under which Seller or Foster would enforce for the
benefit of Buyer, with Buyer assuming Seller's obligations, any
and all rights of Seller or Foster against a third party thereto.
Seller or Foster will promptly pay to Buyer when received all
monies received by Seller under any Purchased Asset or any claim
or right or any benefit arising thereunder, except to the extent
the same represents an Excluded Asset.  In such event, Seller,
Foster and Buyer shall, to the extent the benefits therefrom and
obligations thereunder have not been provided by alternate
arrangements satisfactory to Buyer, Seller and Foster, negotiate
in good faith an adjustment in the consideration paid by Buyer
for the Purchased Assets.

       2.06.  Purchase Price; Allocation of Purchase Price.
(a) The purchase price for the Purchased Assets (the "Purchase
Price") is (i) $200,000 to be paid in shares of common stock of
the Buyer, $.01 par value per share ("Buyer Common Stock"), and
issued at the Closing; such number of shares to be determined in
accordance with Section 2.07(a) below; (ii) the contingent
payments as provided for in Section 2.07(e); and (iii) the
assumption of the Assumed Liabilities.

       (b) Seller and Buyer agree that $10,000 of the Purchase
Price shall be allocated as consideration for the covenant not to
compete set forth in Section 5.04 of this Agreement.

       2.07.  Closing.  The closing (the "Closing") of the
purchase and sale of the Purchased Assets and the assumption of
the Assumed Liabilities hereunder shall take place at the offices
of Testa, Hurwitz & Thibeault, LLP, High Street Tower, 125 High
Street, Boston, Massachusetts 02110 at a time and on a date
mutually agreeable to Buyer, Seller and Foster as soon as
practicable after satisfaction of the conditions set forth in
Article X, but in no event later than September 30, 1997, or at
such other time or place as Buyer, Seller and Foster may agree.
At the Closing,

       (a) Buyer shall deliver to Seller a stock certificate
representing the number of shares of Buyer Common Stock as is
determined by dividing $200,000 by the average of the last
reported sale price of the Buyer Common Stock on the Nasdaq
National Market on each of the ten (10) business days up to and
including the second business day preceding the Closing Date
(subject to appropriate adjustment in the event of a stock split,
reverse stock split, stock dividend or recapitalization by the
Company).  The certificate shall be duly endorsed by the Buyer's
transfer agent and registered in the name of the Seller;

       (b) Seller shall have delivered to Buyer via courier or by
hand all source code and object code of the software forming part
of the Purchased Assets, fully documented, including any and all
related technical and user documentation;

       (c) Seller, Foster and Buyer shall enter into the
Ancillary Agreements and Seller and Foster shall deliver to Buyer
such bills of sale, endorsements, consents, assignments and other
good and sufficient instruments of conveyance and assignment (the
"Conveyance Documents") as the parties and their respective
counsel shall deem reasonably necessary or appropriate to vest in
Buyer all right, title and interest in, to and under the
Purchased Assets.

       (d) Seller and Buyer shall also execute and deliver all
such instruments, documents and certificates as may be reasonably
requested by the other party that are necessary, appropriate or
desirable for the consummation at the Closing of the transactions
contemplated by this Agreement.

       (e) In addition to the payment of stock issued on the
Closing Date as provided for in Section 2.07(a), Buyer shall
issue to Seller up to three (3) additional stock certificates
representing contingent payments from Buyer over the three year
period set forth below.  The number of shares of Buyer Common
Stock issued with respect to each contingent payment will be
determined by dividing the dollar value of the contingent
payment, calculated as set forth below, by the average of the
last reported sale price of Buyer Common Stock on the Nasdaq
National Market on each of the ten (10) business days up to and
including the last day of each Annual Payment Period (as defined
below), subject to appropriate adjustment in the event of a stock
split, reverse stock split, stock dividend or recapitalization by
the Company.  The dollar value of each contingent payment will be
calculated as a percentage of "net receipts" (as defined below)
collected by the Buyer during the period to which the payment
relates (the "Annual Payment Period") and attributable to all
licenses, and complete or partial sales or dispositions by the
Buyer of the software products listed on Schedule 2.07(e), and
their "upgrades" (as defined below), (collectively, the
"Software"), according to the following schedule:

During the period beginning with the Closing Date   7.0% of "net
and ending September 30, 1998 :                     receipts"
During the period beginning October 1, 1998 and     5.0% of "net
ending September 30, 1999:                          receipts"
During the period beginning October 1, 1999 and     3.0% of "net
ending September 30, 2000:                          receipts"

Such contingent payments will be paid to Seller along with a
statement indicating in detail sufficient for Seller to determine
the calculation of such payment, once per year, within 45 days of
the last day of each Annual Payment Period beginning with the
period ending September 30, 1998.  For purposes of this
Section 2.07(e), "net receipts" shall mean all payments actually
received by the Buyer with respect to the Software (including,
but not limited to, royalties, licensing fees, and proceeds of
the complete or partial sale or other disposition of the
Software, but excluding consulting fees, maintenance fees or any
other service fees paid to Buyer in connection with the Software)
net of all sales tax or other similar amounts properly paid or
accrued by the Buyer with respect to such payments so received
and any amounts refunded or rebated by Buyer to payers of amounts
which might otherwise constitute "net receipts".  Notwithstanding
anything in this Section 2.07 to the contrary at such time as
Buyer has issued Common Stock to Seller pursuant to this Section
2.07(e) with a value in the aggregate of $228,000, Buyer's
obligation to issue any additional shares of Common under this
Section 2.07(e) shall cease.  Seller and Foster agree that Buyer
shall use its commercially reasonable best efforts to market and
distribute the Software and continue the sale and promotion of
the Software until at least September 30, 2000; provided,
however, Buyer shall have complete authority related to all
decisions with respect to pricing, shipment terms, return
policies, distribution discounts and all other marketing related
factors in connection with the marketing and distribution of the
Software and shall have no liability to Seller or Foster if
Buyer's commercially reasonable best efforts to market and
distribute the Software are unsuccessful or result in fewer sales
than Seller or Foster expect.  The term "upgrades" shall mean any
modification, enhancement, improvement or version release of the
Software as may be generally commercially licensed by the Buyer
to third parties.

       2.08.  Certificates for Parent Stock.  Each certificate
for Buyer Common Stock issued to the Seller pursuant to this
Agreement shall bear the following legend:

          "The securities represented hereby have not
       been registered under the Securities Act of
       1933, as amended, and may not be sold,
       transferred or otherwise disposed of except in
       accordance with the terms thereof and unless
       registered with the Securities and Exchange
       Commission of the United States and the
       securities regulatory authorities of certain
       states or unless an exemption from such
       registration is available."

                           ARTICLE III

       REPRESENTATIONS AND WARRANTIES OF SELLER AND FOSTER

       Seller and Foster hereby jointly and severally represent
and warrant to Buyer as of the date hereof and as of the Closing
Date that:

       3.01.  Corporate Existence and Power.  Seller is a
corporation duly incorporated, validly existing and in good
standing under the laws of its jurisdiction of incorporation, and
has all corporate powers and all material governmental licenses,
authorizations, consents and approvals required to carry on its
business as now conducted.  Seller is duly qualified to do
business as a foreign corporation and is in good standing in each
jurisdiction where the character of the property owned or leased
by it or the nature of its activities make such qualification
necessary, except for those jurisdictions where failure to be so
qualified would not, individually or in the aggregate, have a
Material Adverse Effect.  Seller has heretofore delivered to
Buyer true and complete copies of the corporate charter and
bylaws of Seller as currently in effect and no action has been
taken or authorized to amend any of such documents.

       3.02.  Authority.  (a) The execution, delivery and
performance by Seller of this Agreement and each of the Ancillary
Agreements, and the consummation by Seller of the transactions
contemplated hereby and thereby are within Seller's corporate
powers and have been duly authorized by all necessary corporate
action on the part of Seller.  This Agreement and each of the
Ancillary Agreements to which Seller is a party constitute valid
and binding agreements of Seller.

       (b) Foster has the legal power, right and authority to
enter into and perform this Agreement, and to perform each of his
obligations hereunder.  The execution, delivery and performance
of this Agreement by Foster does not contravene, or constitute a
default under, any provision of applicable law or regulation or
of any agreement, judgment, injunction, order, decree or any
other instrument binding upon Foster.  This Agreement has been
duly executed and delivered by Foster and constitutes a valid and
binding obligation of Foster, enforceable in accordance with its
terms.

       3.03.  Governmental Authorization.  Except as set forth on
Schedule 3.03, to the knowledge of Seller or Foster, the
execution, delivery and performance by Seller and Foster of this
Agreement and each of the Ancillary Agreements do not require any
action by or in respect of, or filing with, any governmental
body, agency, official or authority.

       3.04.  Non-Contravention.  Except as set forth on Schedule
3.04, to the knowledge of Seller or Foster, the execution,
delivery and performance by Seller and Foster of this Agreement
and each of the Ancillary Agreements and the consummation of the
transactions contemplated hereby do not and will not
(i) contravene or conflict with the corporate charter or bylaws
of Seller, (ii) contravene or conflict with or constitute a
violation of any provision of any law, regulation, judgment,
injunction, order or decree binding upon or applicable to Seller
or the Business; (iii) assuming the receipt of all Required and
other Consents, constitute a default under or give rise to any
right of termination, cancellation or acceleration of any right
or obligation of Seller or to a loss of any benefit relating to
the Business to which Seller is entitled under any provision of
any agreement, contract or other instrument binding upon Seller
or by which any of the Purchased Assets is or may be bound, or
any Permit (as defined below) or (iv) result in the creation or
imposition of any Lien on any Purchased Asset.

       3.05.  Required Consents.  Schedule 3.05 sets forth each
agreement, contract or other instrument binding upon Seller or
Foster or any Permit requiring a consent or any consent that may
be required from any former employees or shareholders of Seller,
as a result of the execution, delivery and performance of this
Agreement and the Ancillary Agreements or the consummation of the
transactions contemplated hereby and thereby (each such consent,
a "Required Consent").

       3.06.  Financial Statements.  Seller has previously
furnished Buyer with a true and complete copy of the Balance
Sheet and the related unaudited statements of operations for the
Business taken as a whole for the years ended December 31, 1996,
the unaudited interim balance sheet relating to the Business for
the six months ended June 30, 1997, and the related unaudited
interim statement of operations for the Business taken as a whole
for the six months ended June 30, 1997, (collectively, the
"Financial Statements") of the Business.  The Financial
Statements fairly present in all material respects the financial
position of the Business as of the dates thereof and its results
of operations for the period then ended.  The Financial
Statements were prepared in accordance with the books and records
of the Seller and are attached hereto as Schedule 3.06.

       3.07.  Absence of Certain Changes.  Since the Balance
Sheet Date, Seller has conducted the Business in the ordinary
course consistent with past practices, and there has not been:

   reasonably be expected to result in a Material Adverse
   Change;

      (b) any declaration, setting aside or payment of any
   dividend or other distribution with respect to any Seller

   maintains cash of at least $5,000 on and as of the Closing
   Date;

      (c) any incurrence, assumption or guarantee by Seller of
   any indebtedness for borrowed money with respect to the

   Seller of any Lien on any Purchased Asset;

   (whether or not covered by insurance) affecting the Business
   or any Purchased Asset which, individually or in the
   aggregate, has had or could reasonably be expected to have a
   Material Adverse Effect;

      (f) any transaction, contract, agreement or other
   instrument entered into, or commitment made, by Seller
   relating to the Business or any Purchased Asset (including
   the acquisition or disposition of any assets) or any
   relinquishment by Seller of any contract or other right, in
   either case, material to the Business taken as a whole, other
   than transactions and commitments in the ordinary course of
   business consistent with past practices and those
   contemplated by this Agreement;

      (g) any change in any method of accounting or accounting
   or collection practice by Seller with respect to the

   off of any notes or accounts receivable or any portion
   thereof as uncollectible, other than valuation reserves
   established for inventory and receivables;

      (n) any cancellation or release of any other debts or
   claims, or waivers of any rights;

      (o) any sale, transfer or conveyance of any property or
   assets, except in the ordinary course of business consistent
   with past practice;

      (p) any disposition of, or lapse, or other failure to
   preserve the exclusive rights of Seller to any Proprietary

knowledge of Seller or Foster, threatened against or affecting,
the Business or any Purchased Asset before any court or
arbitrator or any governmental body, agency, official or
authority.

       3.13.  Material Contracts.  (a)  Except for this
Agreement, any Ancillary Agreement entered into by Seller or

   agreement in respect of similar rights granted to or held by
   Seller;

    (vii) any agency, dealer, sales representative or other

   freedom of the Buyer after the Closing Date;

      (x) any other agreement, contract or commitment not made
   in the ordinary course of business which is material to the
   Business taken as a whole.

       (b) Each Contract disclosed in any Schedule to this
Agreement or required to be disclosed pursuant to Section 3.13(a)
is valid and binding agreement of Seller and is in full force and
effect, and neither Seller nor, to the knowledge of Seller and
Foster, any other party thereto is in default in any material
respect under the terms of any such Contract, nor, to the
knowledge of Seller and Foster, has any event or circumstance
occurred that, with notice or lapse of time or both, would
constitute any event of default thereunder.

       3.14.  Licenses and Permits.  To the knowledge of Seller
and Foster, Schedule 3.14 correctly describes each license,
franchise, permit or other similar authorization affecting, or
relating in any way to, the Business, together with the name of
the government agency or entity issuing such license or permit
(the "Permits"). Such Permits are valid and in full force and
effect and, assuming the related Required Consents have been
obtained prior to the Closing Date, are transferable by Seller
and will not be terminated or impaired or become terminable as a
result of the transactions contemplated hereby.  Upon
consummation of such transactions, Buyer will, assuming the
related Required Consents have been obtained prior to the Closing
Date, have all of the right, title and interest in all the
Permits.

the Balance Sheet are, and all accounts and notes receivable
arising from or otherwise relating to the Business at the Closing
Date will be, valid, genuine and fully collectible in the
aggregate amount thereof, subject to normal and customary trade
discounts.  All accounts, notes receivable and other receivables
arising out of or relating to the Business at the Balance Sheet

terms and conditions immediately following the Closing, except as
otherwise indicated on Schedule 3.19(b).  Seller has taken
reasonable measures to protect the proprietary nature of Seller's
Proprietary Rights and to maintain in confidence the trade
secrets and confidential information that it owns or uses in the
Business.  To Seller's and Foster's knowledge, no other Person
has any rights to any item of Seller's Proprietary Rights or has
any rights to any of Seller's Proprietary Rights, except that the

3.19(a) as licensed to Seller are owned by the respective owners
identified on Schedule 3.19(a), and, to Seller's or Foster's
knowledge, no other Person is infringing, violating or
misappropriating any of  Seller's Proprietary Rights, except as

          (c)  Except as set forth in Schedule 3.19(b), to
Seller's knowledge,  none of the activities or business presently

infringement, violation or misappropriation.

          (d)  Except as set forth in Schedule 3.19(b), with
respect to each item of Seller's Proprietary Rights:

               (i)  Seller possesses all right, title and
          interest in and to such item;
               
               (ii) such item is not subject to any outstanding
          judgment, order, decree, stipulation, injunction or any

          (e)  Schedule 3.19(a) also identifies each item of
Seller's Proprietary Rights used in the operation of the Business
that is owned by a party other than Seller.  All licenses or
other agreements pursuant to which Seller uses such items are
listed on Schedule 3.19(a).  Except as set forth in Schedule
3.19(b), with respect to each such item:

               (i)  the license or other agreement, covering such
          item is legal, valid, binding, enforceable and in full
          force and effect with respect to Seller and Foster,
          and, to Seller's and Foster's knowledge, with respect
          to every other party thereto;
               
               (ii) except as set forth in Schedule 3.19(b), each
          such license or other agreement to which Seller or
          Foster is a party is assignable by Seller or Foster to
          Buyer without the consent or approval of or any payment
          to any party, and all such licenses and other
          agreements will continue to be legal, valid, binding,
          enforceable and in full force and effect immediately
          following the Closing in accordance with the terms
          thereof as in effect immediately prior to the Closing,
          and the consummation of the transactions contemplated
          herein will not conflict with, result in a violation or
          breach of or constitute a default under (or would
          result in a violation, breach or default with the
          giving of notice or the passage of time or both) any
          such license or other agreement;
               
               (iii)     except as set forth in Schedule 3.19(b),
          neither Seller or Foster, nor, to Seller's or Foster's
          knowledge, any other party is in breach or default
          under any such license or other agreement, and no event
          has occurred which, with notice and/or lapse of time,
          would constitute such a breach or default or permit
          termination, modification or acceleration thereunder;
               
               (iv) to Seller's and Foster's knowledge, the
          underlying item of Seller's Proprietary Rights is not
          subject to any outstanding judgment, order, decree,
          stipulation or injunction; and
               
               (v)  Seller or Foster has not agreed to indemnify
          any Person for or against any interference,
          infringement, misappropriation or other conflict with
          respect to such item.

       3.20.  Products.  Each of the products produced or sold by
Seller in connection with the Business (i) is, and at all times
has been, in compliance in all material respects with all
applicable federal, state, local and foreign laws and regulations
and (ii) is, and at all relevant times has been, fit for the
ordinary purposes for which it is intended to be used and
conforms in all material respects to any promises or affirmation
of fact made on the container or liable for such products or in
connection with its sale.  To Seller's or Fosters' knowledge,
there is no design defect with respect to any of such products.

       3.21.  Finders' Fees.  There is no investment banker,

be entitled to any fee or commission from Buyer or Seller or any
of their respective Affiliates upon consummation of the
transactions contemplated by this Agreement.

       3.22.  Other Information.  To Seller's or Foster's
knowledge, none of the documents or information delivered to
Buyer in connection with the transactions contemplated by this

statement of a material fact or omits to state a material fact
necessary in order to make the statements contained therein not
misleading.

to protect the environment and/or human health or safety
(collectively, "Environmental Laws"); (ii) neither Seller nor
Foster has handled, generated, used, stored, transported or

thereof, whether vested or unvested, contingent or fixed, actual
or potential, and (z) arise from or relate to actions occurring
(including any failure to act) or conditions existing on or
before the Closing Date.

       3.24.  Representations.  The representations and
warranties of Seller and Foster contained in this Agreement, as
modified by the corresponding schedules hereto, disregarding all
qualifications and exceptions contained therein relating to
materiality or Material Adverse Effect, are true and correct with
only such exceptions as would not in the aggregate reasonably be
expected to have a Material Adverse Effect.

       3.25.  Purchase for Investment.  The Seller is acquiring
the shares of Buyer Common Stock for investment for its own
account and not with a view to, or for sale in connection with,
any distribution thereof.  The Seller agrees that the shares of
Buyer Common Stock acquired by the Seller may not be sold,
transferred or otherwise disposed of unless such shares are

securities regulatory authorities of certain states or unless an
exemption from such registration is available.

until the Closing Date, Seller shall conduct the Business in the
ordinary course consistent with past practice, use its best
efforts to preserve intact the business organization and
relationships with third parties of the Business, and to keep
available the services of the present employees of the Business.
Without limiting the generality of the foregoing, from the date

          (a) merge or consolidate with any other Person or
   acquire a material amount of assets from any other Person;

          (b) sell, lease, license or otherwise dispose of any

   on and as of the Closing Date;

          (d) adopt or propose any change in its constitutional
   documents; or

          (e) agree or commit to do any of the foregoing.

Seller will not (i) take or agree or commit to take any action

hereunder inaccurate in any respect at, or as of any time prior

take any action necessary to prevent any such representation or
warranty from being inaccurate in any respect at any such time.

       5.02.  Access to Information.  From the date hereof until

(c) will instruct the employees, counsel and financial advisors
of Seller to cooperate with Buyer in its investigation of the
Business; provided that no investigation pursuant to this Section
shall affect any representation or warranty given by Seller
hereunder; and provided further that any investigation pursuant
to this Section shall be conducted in such manner as not to
interfere unreasonably with the conduct of the business of
Seller.

       5.03.  Notices of Certain Events.  Seller shall promptly
notify Buyer of:

      (i) any notice or other communication from any Person
   alleging that the consent of such Person is or may be
   required in connection with the transactions contemplated by
   this Agreement;

     (ii) any notice or other communication from any
   governmental or regulatory agency or authority in connection
   with the transactions contemplated by this Agreement; and

    (iii) any actions, suits, claims, investigations or
   proceedings commenced or, to the best of its knowledge
   threatened against, relating to or involving or otherwise
   affecting Seller or Foster or the Business that, if pending
   on the date of this Agreement, would have been required to
   have been disclosed pursuant to Section 3.12 or that relate
   to the consummation of the transactions contemplated by this
   Agreement.

       5.04.  Noncompetition and Nonsolicitation.  (a) Seller and
Foster agree that for a period of one (1) full year from the
Closing Date, neither Seller, Foster nor any of their respective
Affiliates shall:

      (i) without the Buyer's prior written consent, directly or
   indirectly, alone or as a partner, joint venturer, officer,
   director, employee, consultant, agent, independent
   contractor, unpaid volunteer or stockholder of any company or
   business, engage in any business activity which is or may be
   directly or indirectly in competition with any of the
   products or services developed, marketed, licensed,
   distributed, planned or sold by Seller or Buyer.  The
   ownership by Seller or Foster of not more than two percent of
   the shares of stock of any corporation having a class of
   equity securities actively traded on a national securities
   exchange or on Nasdaq shall not be deemed, in and of itself,
   to violate the prohibitions of this paragraph.

     (ii) solicit, divert or take away, directly or indirectly,
   whether alone or as a sole proprietor, partner, officer,
   director, consultant, employee, joint venturer, agent,
   representative, unpaid volunteer or independent contractor,
   whether for the Seller's or Foster's own interest or for the
   interest of any other person or entity, existing customers or
   business of Seller or Buyer or hire or attempt to hire, or
   solicit, receive or accept the performance of services by, or
   discuss with any employee of Seller or Buyer the employment
   of such employee by, any company, business organization or
   any other entity that develops, licenses, produces or
   manufactures any product or provides services that directly
   or indirectly compete with those developed, produced,
   licensed, manufactured or marketed by Seller or Buyer.

       (b) If any provision contained in this Section shall for
any reason by held invalid, illegal or unenforceable in any
respect, such invalidity, illegality or unenforceability shall
not affect any other provisions of this Section, but this Section
shall be construed as if such invalid, illegal or unenforceable
provision had never been contained herein.  It is the intention
of the parties that if any of the restrictions or covenants
contained herein is held to cover a geographic area or to be for
a length of time which is not permitted by applicable law, or in
any way construed to be too broad or to any extent invalid, such
provision shall not be construed to be null, void and of no
effect, but to the extent such provision would be valid or
enforceable under applicable law, a court of competent
jurisdiction shall construe and interpret or reform this Section
to provide for a covenant having the maximum enforceable
geographic area, time period and other provisions (not greater
than those contained herein) as shall be valid and enforceable
under such applicable law.  Seller acknowledges that Buyer would
be irreparably harmed by any breach of this Section and that
there would be no adequate remedy at law or in damages to
compensate Buyer for any such breach.  Seller agrees that Buyer
shall be entitled to injunctive relief requiring specific
performance  by Seller of this Section, and Seller consents to
the entry thereof.

       5.05.  Confidentiality.  Seller and Foster will hold, and
will use its or his commercially reasonable best efforts to cause
Seller's officers, directors, employees, accountants, counsel,
consultants, advisors and agents to hold, in confidence, unless
compelled to disclose by judicial or administrative process or by
other requirements of law, all confidential documents and
information concerning Buyer or the Business furnished to Seller
or Foster in connection with the transactions contemplated by
this Agreement, and (after the Closing Date) all confidential
documents and information concerning Seller, except to the extent
that such information can be shown to have been (i) previously
known on a nonconfidential basis by Seller or Foster, (ii) in the
public domain through no fault of Seller or Foster or (iii) later
lawfully acquired by Seller or Foster from sources other than
Seller or Buyer; provided that Seller may disclose such
information to Seller's officers, directors, employees,
accountants, counsel, consultants, advisors and agents in
connection with the transactions contemplated by this Agreement
so long as such persons are informed by Seller or Foster of the
confidential nature of such information and are directed by
Seller or Foster to treat such information confidentially.  The
obligation of Seller and Foster to hold any such information in
confidence shall be satisfied if they exercise the same care with
respect to such information as they would take to preserve the
confidentiality of their own similar information but in no event
less than a reasonable degree of care.  If this Agreement is
terminated, Seller and Foster will, and will use their best
efforts to cause Seller's officers, directors, employees,
accountants, counsel, consultants, advisors and agents to,
destroy or deliver to Buyer, upon request, all documents and
other materials, and all copies thereof, obtained by Seller or
Foster, or on their behalf from Buyer in connection with this
Agreement that are subject to such confidence.

       5.06.  Trademarks; Tradenames.  As soon as practicable
after the Closing Date, Seller shall eliminate the use of all of
the trademarks, tradenames, service marks and service names used
in the Business, in any of their forms or spellings, on all
advertising, stationery, business cards, checks, purchase orders
and acknowledgments, customer agreements and other contracts and
all business documents.

       5.07.  No Negotiation with Third Parties.  From the date
hereof until the Closing, Seller and Foster agree not to,
directly or indirectly, through agent, representative,
stockholder or otherwise:  (i) solicit or entertain offers from,
negotiate with or in any manner encourage, discuss, accept or
consider, any proposal of any third party relating to an
investment in Seller or the acquisition of Seller, its capital
stock, its assets (or rights thereto) or its business, in whole
or in part, whether through direct purchase, merger,
consolidation or business combination or licensing transaction
(all such transactions being referred to herein as "Acquisition
Proposals"); (ii) disclose to any third party any non-published
information concerning Seller, its business, or financial
condition in connection with an acquisition or investment in
Seller, provided, however; Seller may disclose such information
to its accountants and legal counsel, or (iii) withdraw their
intention to engage in a transaction with Buyer.  If Seller or
Foster or any of Seller's employees, stockholders, agents, or
representatives receive any unsolicited inquiry (however
preliminary), offer or proposal, Seller or Foster shall promptly
notify Buyer.

       5.08.  Use of Proprietary Rights.  Seller and Foster shall
not use any source materials (any source code, algorithms,
computer program designs, subroutines, system specifications and
other technical information relating to the development and
architecture of the software included in the Purchased Assets and
the design, configuration, programming or protocol relating to
such software) transferred as part of the Purchased Assets for
its own benefit, or for the benefit of others, except, in the
case of Foster who is a natural person, in his capacity as an
employee of Buyer or for inadvertent and incidental uses as may

                       COVENANTS OF BUYER

       Buyer agrees that:

       6.01.  Confidentiality. Prior to the Closing Date and
after any termination of this Agreement, Buyer and its Affiliates
will hold, and will use their commercially reasonable best
efforts to cause their respective officers, directors, employees,
accountants, counsel, consultants, advisors and agents to hold,
in confidence, unless compelled to disclose by judicial or
administrative process or by other requirements of law, all
confidential documents and information concerning the Business or
Seller furnished to Buyer or its Affiliates in connection with
the transactions contemplated by this Agreement, except to the
extent that such information can be shown to have been
(i) previously known on a nonconfidential basis by Buyer, (ii) in
the public domain through no fault of Buyer or (iii) later
lawfully acquired by Buyer from sources other than Seller;
provided that Buyer may disclose such information to its
officers, directors, employees, accountants, counsel,
consultants, advisors and agents in connection with the
transactions contemplated by this Agreement so long as such
persons are informed by Buyer of the confidential nature of such
information and are directed by Buyer to treat such information
confidentially.  The obligation of Buyer and its Affiliates to
hold any such information in confidence shall be satisfied if
they exercise the same care with respect to such information as
they would take to preserve the confidentiality of their own
similar information but in no event less than a reasonable degree
of care.  If this Agreement is terminated, Buyer and its
Affiliates will, and will use their best efforts to cause their
respective officers, directors, employees, accountants, counsel,
consultants, advisors and agents to, destroy or deliver to

for the benefit of Buyer (i) to collect for the account of Buyer
any items of Purchased Assets and (ii) to institute and prosecute
all proceedings which Buyer may in its sole discretion deem
proper in order to assert or enforce any right, title or interest
in, to or under the Purchased Assets, and to defend or compromise
any and all actions, suits or proceedings in respect of the
Purchased Assets.  Buyer shall be entitled to retain for its
account any amounts collected pursuant to the foregoing powers,
including any amounts payable as interest in respect thereof.

       7.02.  Certain Filings.  Seller and Buyer shall cooperate
with one another (a) in determining whether any action by or in

       (a) Seller has timely paid all Taxes, and all interest and
penalties due thereon and payable by it, for the Pre-Closing Tax

the Closing Date.

       (b) Seller has established, in accordance with generally

result in Buyer becoming liable therefor.

the Seller with respect to, or which may relate to, items of
income, gain, deduction, loss or credit of Seller, and no such
audit of Seller is in progress and Foster has not received notice

pending.

       8.03.  Tax Cooperation; Allocation of Taxes.  (a) Buyer
and Seller agree to furnish or cause to be furnished to each
other, upon request, as promptly as practicable, such information

making of any election related to Taxes, the preparation for any
audit by any taxing authority, and the prosecution or defense of
any claim, suit or proceeding relating to any Tax return.  Seller
and Buyer shall cooperate with each other in the conduct of any
audit or other proceeding related to Taxes involving the Business

the Closing Date based on the number of days of such taxable
period included in the Pre-Closing Tax Period and the number of

such taxes that is attributable to the Pre-Closing Tax Period.

a statement to the other setting forth the amount of
reimbursement to which each is entitled under this
Section 8.03(b) together with such supporting evidence as is
reasonably necessary to calculate the proration amount.  The
proration amount shall be paid by the party owing it to the other
within 10 days after delivery of such statement.  Thereafter,
Seller shall notify Buyer upon receipt of any bill for real or
personal property taxes relating to the Purchased Assets, part or
all of which are attributable to the Post-Closing Tax Period, and
shall promptly deliver such bill to Buyer who shall pay the same
to the appropriate taxing authority, provided that if such bill
covers the Pre-Closing Tax Period, Seller shall also remit prior
to the due date of assessment to Buyer payment for the
proportionate amount of such bill that is attributable to the Pre-
Closing Tax Period.  If either Seller or Buyer shall thereafter
make a payment for which it is entitled to reimbursement under
this Section 8.03(b), the other party shall make such
reimbursement promptly but in no event later than 30 days after
the presentation of a statement setting forth the amount of
reimbursement to which the presenting party is entitled along
with such supporting evidence as is reasonably necessary to
calculate the amount of reimbursement.  Any payment required
under this Section and not made within 10 days of delivery of the
statement shall bear interest at the rate per annum determined,
from time to time, under the provisions of Section 6621(a)(2) of
the Code for each day until paid.

assessed upon or with respect to the transfer of the Purchased
Assets to Buyer and any recording or filing fees with respect
thereto shall be the responsibility of Seller.

income tax purposes the transaction evidenced by this Agreement

in any employee or former employee (including any beneficiary or
dependent thereof) of Seller in respect of continued employment
(or resumed employment) with either Buyer or the Business or any
of their Affiliates and no provision of this Article IX shall
create any such rights in any such Persons in respect of any
benefits that may be provided, directly or indirectly, under any

terminated at any time prior to the Closing:

      (i) by mutual written agreement of Seller, Foster and

   on September 30, 1997; provided, however, that the right to
   terminate this Agreement under this Section 12.01 shall not
   be available to any party whose action or failure to act has
   been a principal cause of or resulted in the failure of the
   Closing to occur on or before such date and such action or
   failure to act constitutes a breach of this Agreement;

    (iii) by either Seller or Buyer if there shall be any law or
   regulation that makes the consummation of the transactions
   contemplated hereby illegal or otherwise prohibited or if
   consummation of the transactions contemplated hereby would
   violate any nonappealable final order, decree or judgment of
   any court or governmental body having competent jurisdiction;

     (iv) by Buyer, if there shall have occurred any Material
   Adverse Change in the financial condition, results of
   operations, business, properties, assets or operations of
   Seller since the date of this Agreement;

      (v) by Buyer, upon breach of any representation, warranty,
   covenant or agreement on the part of Seller or Foster set
   forth in this Agreement, or if any representation or warranty
   of Seller or Foster shall have become untrue, in either case
   such that the conditions set forth in Section 10.02(a) would
   not be satisfied as of the time of such breach or as of the
   time such representation or warranty shall have become
   untrue;

     (vi) by Seller, upon a breach of any representation,
   warranty, covenant or agreement on the part of Buyer set
   forth in this Agreement, or if any representation or warranty
   of Buyer shall have become untrue, in either case such that

this Section 12.01 shall give notice of such termination to the
other party.

       12.02.  Effect of Termination.  If this Agreement is
terminated as permitted by Section 12.01, such termination shall
be without liability of either party (or any shareholder,
director, officer, employee, agent, consultant or representative
of such party) to the other party to this Agreement; provided
that if such termination shall result from the willful failure of
either party to fulfill a condition to the performance of the
obligations of the other party or to perform a covenant of this
Agreement or from a willful breach by either party to this
Agreement, such party shall be fully liable for any and all
Losses incurred or suffered by the other party as a result of
such failure or breach.  The provisions of Sections 6.01 and
13.03 shall survive any termination hereof pursuant to
Section 12.01.

     RE:   Registration Statement on Form S-3
           Relating to 295,944 shares of Common Stock

Dear Sir or Madam:

     We are counsel to PAREXEL International Corporation, a
Massachusetts corporation (the "Company"), and have
represented the Company in connection with the preparation
and filing of the Company's Registration Statement on Form S-
3 (the "Registration Statement"), covering the resale to the
public of up to 295,944 shares of the Company's Common
Stock, $.01 par value per share, by certain stockholders of
the Company (the "Shares").

     We have reviewed the corporate proceedings taken by the
Board of Directors of the Company with respect to the
authorization and issuance of the Shares.  We have also
examined and relied upon originals or copies, certified or
otherwise authenticated to our satisfaction, of all
corporate records, documents, agreements or other
instruments of the Company and have made all investigations
of law and have discussed with the Company's officers all
questions of fact that we have deemed necessary or
appropriate.

     Based upon and subject to the foregoing, we are of the
opinion that the Shares are legally issued, fully paid and
non-assessable.

     We hereby consent to the filing of this opinion as
Exhibit 5.1 to the Registration Statement and to the
reference to our firm in the Prospectus contained in the
Registration Statement under the caption "Legal Matters."

                                   Very truly yours,
                                   
                                   
                                   /s/ Testa, Hurwitz &

            Consent of Independent Accountants

3 of our report dated August 16, 1997, except as to the
Note 16 and pooling of interests with Kemper-Masterson, Inc., which is
