                                 THE COMPANY 

   Premier Research Worldwide, Ltd. (the "Company") is a clinical research 
organization ("CRO") providing a broad range of integrated product 
development services to its clients in the pharmaceutical, biotechnology and 
medical device industries. The Company complements the research and 
development departments of its clients by offering high quality clinical 
research services on an as-needed basis, thereby providing a variable cost 
alternative to certain fixed costs typically associated with internal product 
development. Over the last three years, the Company has built a base of over 
100 clients, including 23 of the 25 largest pharmaceutical companies in the 
world. In the first nine months of 1996, the Company performed services under 
96 contracts for 62 clients. The Company's services include centralized 
diagnostic testing, clinical trial management, clinical data management, 
biostatistical analysis, Phase I clinical research, health care economics and 
outcomes research and regulatory affairs services. 

   Throughout its history, the Company has been an innovator in the use of 
new technologies that speed product development and regulatory review. For 
example, the Company created and filed the first computer-assisted new drug 
application ("CANDA") with the United States Food & Drug Administration 
("FDA"). The Company's technology is designed to simplify and make more 
efficient the collection, transfer, analysis and preparation of clinical 
trial data. The Company believes that its proprietary technology links all 
facets of clinical development, produces cost advantages, facilitates 
superior levels of service, improves the quality of clinical research, and 
enhances the Company's global capabilities. 

   All of the Company's services are designed to help clients reduce their
product development time in a cost-effective manner. In 1977, the Company's
predecessor, Cardio Data Systems, began providing diagnostic testing services
used to evaluate the safety and efficacy of new drugs. Today, the Company
provides these services, which include electrocardiograms ("ECGs"), Holter
monitoring, pulmonary function testing, blood and urine sampling, and other
tests, on a centralized basis. To take advantage of the potential synergies and
cross-selling opportunities with its centralized diagnostic testing services,
the Company added clinical trial management capabilities in September 1995 by
forming a limited liability company with PREMIER, Inc., which is owned 65% by
the Company and 35% by PREMIER, Inc. Upon the closing of this offering, PREMIER,
Inc.'s minority interest will convert into 330,150 shares of Common Stock of the
Company. Although a substantial majority of the Company's net revenues is still
derived from centralized diagnostic testing services, the Company today has the
capacity to provide the full range of CRO services on a global basis.

   The Company believes that its affiliation with PREMIER, Inc. will improve 
its ability to market and enhance its clinical research services to its 
clients. PREMIER, Inc. is the largest voluntary healthcare alliance in the 
United States, with 1,800 affiliated hospitals and institutions, located in 
all 50 states, representing over 300,000 hospital beds. PREMIER, Inc. 
negotiated, on behalf of the alliance, group purchases of approximately $6 
billion of medical devices, supplies and pharmaceuticals in 1995, and expects 
to negotiate group purchases of approximately $10 billion in 1996. The 
Company seeks to leverage its strategic 


                                      3 
<PAGE>

relationship with PREMIER, Inc. in the following ways: (i) PREMIER, Inc. has 
agreed to introduce the Company to all pharmaceutical and device companies 
that sell or propose to sell products to the alliance; (ii) PREMIER, Inc. has 
agreed to include as a standard provision in all of its future drug and 
device group purchasing agreements that the pharmaceutical or device company 
consider using the Company's services in its clinical trials; (iii) the 
Company is the exclusive CRO for the trial management organization being 
developed by PREMIER, Inc. with the assistance of the Company; and (iv) the 
Company has access to PREMIER, Inc.'s databases, which should facilitate the 
Company's ability to identify specific patient populations, investigators and 
sites and to offer pharmacoeconomic and outcomes data to its clients. 

   The global pharmaceutical and biotechnology industries spent an estimated 
$35 billion in 1995 on research and development, of which the Company 
estimates $20 billion was spent on the types of services offered by the 
Company. Of this amount, approximately $2.5 billion was outsourced to CROs. 

   The Company believes that the following trends will lead to increased 
outsourcing of product development activities by pharmaceutical, 
biotechnology and medical device companies: (i) clients in these industries 
are increasingly seeking faster product development times in order to 
maximize the period of patent protection and marketing exclusivity; (ii) as 
these companies respond to cost containment pressures, they are looking to 
develop their products as inexpensively as possible and therefore are taking 
advantage of the variable cost structure of outsourcing to CROs versus the 
fixed cost structure of internal development; (iii) as increasingly complex 
and stringent regulatory requirements have added to the volume of data 
required for regulatory filings, the demand for comprehensive capabilities to 
collect, analyze and prepare clinical data for regulatory submission is 
growing; (iv) as pharmaceutical and biotechnology companies are developing 
more advanced therapeutics for complex chronic diseases, these companies are 
looking to outsource to CROs with product development expertise in 
specialized therapeutic areas; (v) biotechnology companies are developing an 
increasing number of new drugs submitted for regulatory review and continue 
to depend largely on outside sources for clinical research services; (vi) the 
shift by pharmaceutical, biotechnology and medical device companies from 
making sequential filings of registration packages to simultaneous filings in 
several countries is creating growing demand for CROs with an international 
presence and experience in preparing such filings; and (vii) the need for 
sophisticated data management is increasing. 

   The Company's objective is to accelerate its clients' product development 
timelines. The Company's strategies for meeting this objective include: (i) 
using innovative technology to accelerate and improve product development; 
(ii) providing comprehensive product development services, including 
centralized diagnostic testing services; (iii) expanding its capacity for 
global product development services; (iv) developing its strategic 
relationship with PREMIER, Inc.; and (v) pursuing strategic acquisitions.

                                 RISK FACTORS 


   In addition to the other information in this Prospectus, prospective 
purchasers should consider carefully the risk factors set forth below in 
evaluating an investment in the shares of the Common Stock of the Company 
offered hereby. 


DEPENDENCE ON CERTAIN INDUSTRIES AND CLIENTS 


   The Company's net revenues are highly dependent on research and 
development expenditures by the pharmaceutical, medical device and 
biotechnology industries. The Company has benefited from the growing tendency 
of pharmaceutical, medical device and biotechnology companies to outsource 
their product development projects to independent CROs. Any reduction in the 
outsourcing of research and development expenditures in these industries 
could have a material adverse effect on the Company. The Company has in the 
past derived, and may in the future derive, a significant portion of its net 
revenues from a relatively limited number of major projects or clients. In 
1994, two clients accounted for 17.0% and 11.5% of net revenues, in 1995 
three clients accounted for 15.0%, 12.1% and 10.0% of net revenues, and in 
the first nine months of 1996, three clients accounted for 15.3%, 10.5% and 
10.4% of net revenues. Customer concentration in the CRO industry is not 
uncommon and the Company is likely to experience such concentration in the 
future. The loss of any such client could have a material adverse effect on 
the Company. See "Business -- Clients." 


LOSS OR DELAY OF CONTRACTS 


   Most of the Company's contracts are terminable without cause upon 30 to 90
days notice by the client. Clients terminate or delay contracts for various
reasons including, among others, the failure of the product being tested to
satisfy safety or efficacy requirements; unexpected or undesired clinical
results of the product; the client's decision to forego a particular study;
insufficient patient enrollment or investigator recruitment; and production
problems resulting in shortages of required clinical supplies. In the nine
months ended September 30, 1996, 16 Company contracts were terminated for which
the remaining contract amounts totalled approximately $3.0 million. In addition,
the Company believes that several factors, including the potential impact of
health care reform, have caused pharmaceutical, biotechnology and medical device
companies to apply more stringent criteria to the decision to proceed with
clinical trials and may result in a greater willingness of these companies to
terminate such trials. Therefore, the Company does not believe that its backlog
as of any date is necessarily a meaningful predictor of future results. Although
the Company's contracts typically require non-refundable, up-front payments and
contain a provision for the payment of certain fees in closing a study after
early termination, the loss or delay of a large project or contract or the loss
or delay of multiple smaller contracts could have a material adverse effect on
the Company. See "Management's Discussion and Analysis of Financial Condition
and Results of Operations" and "Business -- Backlog."


RISKS ASSOCIATED WITH UNPROVEN BUSINESS STRATEGIES 


   The Company did not offer clinical trial management services until September
1995. While the Company's objective is to expand its CRO business, diagnostic
testing services continue to be the Company's largest product offering,
constituting 65.1% and 82.5% of the Company's net revenues for 1995 and the nine
months ended September 30, 1996, respectively. The Company's efforts to expand
its CRO business are at an early stage, and there can be no assurance that the
Company will be able to expand this area in a profitable manner. One of the
Company's strategies is to leverage its affiliation with PREMIER, Inc. While the
Company believes that this strategic relationship provides it with various
competitive advantages, there can be no assurance that the contemplated
beneficial effects of the relationship will materialize. The Company's prospects
must be considered in light of the risks, expenses and difficulties frequently
encountered by companies expanding into a new business area or utilizing a new
strategy, particularly companies in rapidly evolving markets, and there can be
no assurance that the Company will be successful in these efforts. See "Business
- -- The Company's Strategy."


                                        6
<PAGE>

MANAGEMENT OF GROWTH 


   The Company expects to grow rapidly in the next few years, especially in 
its clinical trial management and data management services. The Company 
believes that sustained growth places a strain on operational, human and 
financial resources. To manage its growth, the Company must continue to 
improve its operating and administrative systems and to attract and retain 
qualified management, professional, scientific and technical operating 
personnel. Foreign operations also involve the additional risks of 
assimilating differences in foreign business practices, hiring and retaining 
qualified personnel and overcoming language barriers. Failure to manage 
growth effectively could have a material adverse effect on the Company. 


DEPENDENCE ON KEY PERSONNEL 


   The Company relies on a number of key executives including Joel 
Morganroth, M.D., its President and Chief Executive Officer; Christopher 
Gallen, M.D., Ph.D., President, Clinical Research Services; Glenn Cousins, 
President, Diagnostic Services; and David Evans, Senior Vice President and 
Chief Technical Officer. The loss of the services of any of the Company's key 
executives could have a material adverse effect on the Company. There can be 
no assurance the Company will be able to continue to attract and retain 
qualified personnel. See "Business -- Employees" and "Management." 

VARIATION IN QUARTERLY OPERATING RESULTS; SEASONALITY 

   The Company's quarterly operating results have been and will continue to 
be subject to variation, depending on factors such as the commencement, 
completion or cancellation of significant contracts, the mix of contracted 
services, foreign exchange rate fluctuations, the timing of start-up expenses 
for new offices and services, and the costs associated with integrating 
acquisitions. The Company has experienced, and expects to experience in the 
future, seasonal variations in its revenues. The Company believes that 
quarterly comparisons of its financial results should not be relied upon as 
an indication of future performance. See "Management's Discussion and 
Analysis of Financial Condition and Results of Operations -- Quarterly 
Results." 


ACQUISITION RISKS 


   The Company reviews acquisition candidates in the ordinary course of its 
business. Acquisitions involve numerous risks, including the expenses 
incurred in connection with the acquisition, difficulties in assimilating 
operations and products, 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 involve the additional risks 
of assimilating differences in foreign business practices, hiring and 
retaining qualified personnel and overcoming language barriers. There can be 
no assurance that any future acquisitions will be successfully integrated 
into the Company's operations. See "Use of Proceeds" and "Business -- The 
Company's Strategy." 

   Due to the fact that the Company has been a subsidiary of UM, it will not 
be eligible to use the pooling of interests method of accounting for 
acquisitions made during the two year period following this offering, which 
could make potential acquisitions less attractive to the Company. 


COMPETITION; INDUSTRY CONSOLIDATION 


   The CRO industry is highly fragmented, with several hundred CROs ranging 
in size from one person consulting firms to full-service, global product 
development organizations. The Company primarily competes against other CROs, 
some of which possess substantially greater capital, technical and other 
resources than the Company. To a lesser extent, the Company also competes 
against universities and teaching hospitals. As a result of competitive 
pressures and the potential for economies of scale, the industry is 
consolidating. This trend is likely to produce increased competition among 
the larger CROs for clients and acquisition candidates. There are few 
barriers to entry for small, limited-service entities entering the CRO 
industry and these entities also may compete with established CROs for 
clients. The Company believes that major pharmaceutical, biotechnology and 
medical device companies tend to develop preferred provider relationships 
with full-service CROs, effectively excluding smaller CROs from the bidding 
process. The Company may find reduced access to certain potential 


                                        7
<PAGE>


clients due to these arrangements. In addition, the CRO industry has 
attracted the attention of the investment community, which could lead to 
increased competition by increasing the availability of financial resources 
for CROs. Increased competition may lead to price and other forms of 
competition that could adversely affect the Company. See "Business -- 
Competition." 


DEPENDENCE ON PROPRIETARY TECHNOLOGY; ABILITY TO RESPOND TO TECHNOLOGICAL 
CHANGE 


   The Company relies principally upon trade secret and contract law to 
protect its proprietary technology, and there can be no assurance that such 
measures will prove adequate. The Company's future success depends in part 
upon its ability to enhance its current technology and to develop and 
introduce new technology that keeps pace with technological developments and 
the sophisticated needs of its clients. There can be no assurance that the 
Company will successfully develop and introduce such enhancements or new 
technologies. In addition, there can be no assurance that products or 
technologies developed by others will not render the Company's technology 
non-competitive or obsolete. 


POTENTIAL LIABILITY 


   The Company could be held liable for errors or omissions in connection 
with any of the services it performs. Clinical research services involve the 
testing of new drugs and devices on human volunteers pursuant to a study 
protocol that has been approved by an impartial review board with medical and 
non-medical members. Such testing exposes the Company to the risk of 
liability for personal injury or death to patients resulting from their 
participation in the study, including, among other things, possible 
unforeseen adverse side effects or improper use of a new drug or device. Many 
of these patients are already seriously ill and are at risk of further 
illness or death. In addition, the Company could be liable for the general 
risks associated with its Phase I clinical research unit, where healthy and 
at times unhealthy volunteers are housed and treated. Potential liabilities 
include, but are not limited to, unforeseen adverse side effects resulting 
from the use of new drugs or devices and the professional malpractice of 
medical care providers. The Company could be materially adversely affected if 
it were required to pay damages or incur defense costs in connection with a 
claim that is beyond the scope of an indemnity provision or beyond the scope 
or level of insurance coverage maintained by it or the client, or where the 
indemnifying party does not fulfill its indemnification obligations. In 
addition, there can be no assurance that such insurance will continue to be 
available on terms acceptable to the Company. See "Business -- Potential 
Liability and Insurance." 

DEPENDENCE ON GOVERNMENT REGULATION 

   Human pharmaceutical products, biological products, and medical devices 
are subject to rigorous regulations by the federal government, principally 
the FDA, and foreign governments if products are tested or marketed abroad. 
In the United States, the Federal Food, Drug, and Cosmetic Act ("FFDCA") 
governs clinical trials and approval procedures, as well as the development, 
manufacturing, safety, labeling, storage, record keeping and marketing of 
pharmaceutical products and medical devices. Biological products are subject 
to similar regulation under both the FFDCA and the Public Health Service Act. 
Because the Company offers services relating to the conduct of clinical 
trials and the preparation of marketing applications, the Company is 
obligated to comply with applicable regulatory requirements governing these 
activities, both in the United States and in foreign countries. Requirements 
governing these activities vary from country to country. 

   A relaxation in the scope of regulatory requirements, such as the 
introduction of simplified marketing applications for pharmaceuticals, 
biologics, or medical devices, could decrease the business opportunities 
available to the Company. In addition, the Company's failure to comply with 
applicable regulations relating to the conduct of clinical trials or the 
preparation of marketing applications could lead to a variety of sanctions. 
For example, regulatory violations in the United States could result, 
depending on the nature of the violation and the type of product involved, in 
the issuance of a Warning Letter; termination of a clinical study; refusal of 
the FDA to approve clinical trial or marketing applications or withdrawal of 
such applications; injunction; seizure of investigational products; civil 
penalties; criminal prosecutions; or debarment of the Company from assisting 
in the submission of abbreviated drug applications for generic drugs. Such 
sanctions could have a material adverse effect on the Company. 

                                      8

<PAGE>


   The Company's laboratory services are subject to regulation under the 
Clinical Laboratory Improvement Amendments of 1988. Violations of these 
requirements can lead to a variety of sanctions, including enjoining the 
Company from providing laboratory services, which could have a material 
adverse effect on the Company. See "Business -- Industry Trends" and 
"Business -- Government Regulation." 


UNCERTAINTY IN HEALTH CARE INDUSTRY AND POTENTIAL HEALTH CARE REFORM 


   The federal and numerous state governments have undertaken efforts to 
control growing health care costs through legislation, regulation and 
voluntary agreements with medical care providers and pharmaceutical, 
biotechnology and medical device companies. In recent 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 to reduce the growth of total health care 
expenditures. While none of the comprehensive proposals was adopted, health 
care reform may again be addressed by the U.S. Congress. Implementation of 
comprehensive or incremental government health care reform, as well as 
industry-wide health care cost containment pressures, may adversely affect 
research and development expenditures by pharmaceutical, biotechnology and 
medical device companies, which could decrease the business opportunities 
available to the Company. The Company is unable to predict the likelihood of 
such legislation being enacted into law or the effects such legislation would 
have on the Company. See "Business -- Industry Overview." 


EXCHANGE RATE FLUCTUATIONS 


   The Company expects net revenues derived from operations outside the 
United States to grow in future years. For 1993, 1994, 1995 and the nine 
months ended September 30, 1996, the Company's non-U.S. net revenues 
represented 13.5%, 17.0%, 9.8% and 15.8%, respectively, of total net 
revenues. Since the revenues and expenses of the Company's foreign operations 
generally are denominated in foreign currencies, exchange rate fluctuations 
between such foreign currencies and the United States dollar will subject the 
Company to currency translation risk with respect to the reported results of 
its foreign operations, as well as to risks sometimes associated with 
international operations. See "Management's Discussion and Analysis of 
Financial Condition and Results of Operations." 


NO PRIOR MARKET; POSSIBLE VOLATILITY OF STOCK PRICE 


   Prior to this offering, there has been no public market for the Company's 
Common Stock, and there can be no assurance that an active public market will 
develop or be sustained after the offering. The initial public offering price 
will be determined through negotiations between the Company and the 
Underwriters and may not be indicative of future market prices. See 
"Underwriting" for a discussion of the factors to be considered in 
determining the initial public offering price. The market price of the 
Company's Common Stock could be subject to wide fluctuations in response to 
variations in operating results from quarter to quarter, changes in earnings 
estimates by analysts, market conditions in the industry and general economic 
conditions. Furthermore, the stock market has experienced, and may further 
experience in the future, significant price and volume fluctuations unrelated 
to the operating performance of particular companies. These market 
fluctuations may have a material adverse effect on the market price of the 
Company's Common Stock. 


THE EFFECT OF CERTAIN CHARTER PROVISIONS; PREFERRED STOCK ISSUANCE 

   The Company's Certificate of Incorporation requires an affirmative 
super-majority (80%) stockholder vote before the Company can enter into 
certain defined business combinations, except for combinations that meet 
certain specified conditions. The Certificate of Incorporation also provides 
for staggered three year terms for members of the Board of Directors. The 
Company has 500,000 authorized shares of Preferred Stock, none of which will 
be outstanding upon completion of the offering. Pursuant to the Certificate 
of Incorporation, the Board of Directors has the authority to issue Preferred 
Stock in one or more series, and to fix the rights, preferences, privileges 
and restrictions, including dividend, conversion, voting, redemption 
(including sinking fund provisions) and other rights, liquidation preferences 
and the number of shares constituting any series and the 

                                        9
<PAGE>


designation of such series, without any further vote or action by the 
stockholders of the Company. These charter provisions could have the effect 
of discouraging potential take-over attempts and may make attempts by 
stockholders to change the management of the Company more difficult. See 
"Description of Capital Stock." 


DILUTION TO NEW INVESTORS 

   Purchasers of Common Stock in this offering will experience immediate and 
substantial dilution in the net tangible book value per share of the Common 
Stock. See "Dilution." 

RISK OF HAZARDOUS MATERIAL CONTAMINATION 


   The Company's clinical activities have involved, and may continue to 
involve, the controlled use of hazardous materials. Although the Company 
believes that its safety procedures for handling the disposal of such 
materials comply with the standards prescribed by state and federal laws and 
regulations, the risk of accidental contamination or injury from these 
materials cannot be completely eliminated. In the event of such an accident, 
the Company could be held liable for damages which, to the extent not covered 
by existing insurance or indemnification, could have a material adverse 
effect on the Company. 


CONCENTRATION OF OWNERSHIP IN CURRENT STOCKHOLDERS, OFFICERS, AND DIRECTORS 


   Following this offering, the Company's current stockholders, executive 
officers, and directors will beneficially own approximately 62.2% of the 
outstanding shares of Common Stock. As a result, such persons will have the 
ability to control the election of the Company's directors and the outcome of 
corporate actions requiring stockholder approval. This concentration of 
ownership could have the effect of discouraging potential take-over attempts 
and may make more difficult attempts by stockholders to change the management 
of the Company. 


ABSENCE OF DIVIDENDS 

   The Company has no present plans to pay cash dividends to its stockholders 
and, for the foreseeable future, intends to retain all of its earnings for 
use in its business. The declaration of any future dividends by the Company 
is within the discretion of its Board of Directors and will be dependent on 
the earnings, financial condition and capital requirements of the Company, as 
well as any other factors deemed relevant by its Board of Directors. See 
"Dividend Policy." 

SHARES ELIGIBLE FOR FUTURE SALE 


   Upon completion of this offering, of the 15,000,000 authorized shares of 
Common Stock, 7,272,591 shares will be issued and outstanding or reserved for 
issuance pursuant to the exercise of outstanding stock options. Upon 
completion of this offering, the Company will have 6,732,150 shares of Common 
Stock outstanding. The 2,750,000 shares offered hereby will be freely 
tradeable without restriction under the Securities Act of 1933, as amended 
(the "Securities Act"), except for any such shares held by "affiliates" of 
the Company within the meaning of the Securities Act, which will be subject 
to the resale limitations of Rule 144 promulgated under the Securities Act 
("Rule 144"). The Company believes that the remaining outstanding shares, and 
the 540,441 shares issuable upon exercise of outstanding options, may be sold 
pursuant to Rule 144 or Rule 701 under the Securities Act in compliance with 
the limitations thereof beginning 90 days after the offering. In accordance 
with the terms of the lock-up agreements entered into with the Company, the 
Company's directors, executive officers, and stockholders have agreed not to 
sell the shares owned by each of them without the prior written consent of 
Montgomery Securities for a period of 180 days (365 days, in the case of Dr. 
Morganroth) following the first offer of shares of Common Stock pursuant to 
this Prospectus. See "Shares Eligible for Future Sale." 


                               COMPANY HISTORY 


   The Company is a Delaware corporation. It and its predecessors have 
operated since 1977 as direct or indirect subsidiaries or as divisions of UM 
Holdings, Ltd. ("UM"), a holding company that owns several companies in 
different industries. The Company's original predecessor, Cardio Data 
Systems, began providing Holter monitoring analysis services to 
pharmaceutical companies developing new drugs. Over time, additional 
diagnostic testing services were added, and this business became separately 
operated as CDS Research. In 1984, UM 


                                       10
<PAGE>

acquired Research Data Corporation ("RDC"), a provider of specialized data 
processing services designed to aid pharmaceutical companies submitting new 
drugs for regulatory approval. RDC pioneered the computer assisted new drug 
application ("CANDA"), filing the first CANDA in 1985. 


   The CDS Research and RDC divisions were operationally combined in 1993 to 
form Research Data Worldwide. In the same year, the Company opened its Phase 
I clinical research unit. The Company was incorporated in Delaware in 1993 
and became operational when UM contributed the Research Data Worldwide 
division to it in June 1994. 

   To take advantage of the potential synergies and cross-selling opportunities
with its centralized diagnostic testing services, the Company added clinical
trial management capabilities in September 1995 by forming a limited liability
company with PREMIER, Inc., which is owned 65% by the Company and 35% by
PREMIER, Inc. PREMIER, Inc. is the nation's largest voluntary healthcare
alliance, with 1,800 affiliated hospitals and institutions located in all 50
states representing over 300,000 hospital beds. Upon the closing of this
offering, PREMIER, Inc.'s minority interest in the limited liability company
will convert into 330,150 shares of the Company's Common Stock, representing
approximately 4.9% of the outstanding Common Stock. Shortly after forming the
limited liability company, the Company changed its name to Premier Research
Worldwide, Ltd.


   The Company's principal executive offices are located at 124 South 15th 
Street, Philadelphia, Pennsylvania 19102. Its telephone number is 
215-972-0420. 

                               USE OF PROCEEDS 


   The net proceeds to the Company from the sale of 2,000,000 shares of 
Common Stock offered by the Company pursuant to this offering are estimated 
to be $27.3 million ($30.2 million if the Underwriters over-allotment option 
is exercised in full) at an assumed initial public offering price of $15.00 
per share and after deducting the estimated underwriting discount and 
estimated offering expenses payable by the Company. The Company will not 
receive any of the proceeds from the sale of Common Stock by the Selling 
Stockholder. 

   The Company intends to use the net proceeds of this offering for capital 
expenditures (including expansion of facilities, acquisition of equipment and 
development and improvement of information technology systems), geographic 
expansion, possible future acquisitions, working capital and other general 
corporate purposes. The Company has no commitments or agreements with respect 
to any acquisition. Pending such uses, the Company intends to invest the net 
proceeds from this offering in short-term, investment-grade, interest bearing 
securities. 


                               DIVIDEND POLICY 


   Until 1996, UM maintained a central cash management function for all of 
its subsidiaries, including the Company. Settlement of cash disbursement and 
collection transactions by UM on behalf of the Company have been recorded 
through equity in the historical financial statements. See Consolidated 
Financial Statements, including Notes thereto. The Company made net 
distributions to UM for the nine months ended September 30, 1996 of $687,000 
and is committed to make additional distributions of $450,000 to UM in the 
fourth quarter of 1996. After the closing of this offering, the Company 
intends to retain any earnings for future growth, does not anticipate paying 
any cash dividends on its Common Stock in the foreseeable future and will not 
make any further distributions to UM.

                                   DILUTION 


   At September 30, 1996, the Company's pro forma net tangible book value was 
approximately $2.4 million, or $.51 per common share after giving effect to 
(i) the conversion of PREMIER, Inc.'s minority interest in the limited 
liability company into 330,150 shares of Common Stock of the Company upon the 
closing of this offering and (ii) distributions of $450,000 to be paid to UM 
in the fourth quarter of 1996. Pro forma net tangible book value per share is 
equal to the Company's total tangible assets less total liabilities divided 
by the total number of shares of Common Stock outstanding on a pro forma 
basis. After giving effect to the sale of the 2,000,000 shares of Common 
Stock offered by the Company hereby (at an assumed initial public offering 
price of $15.00 per share and after deducting the estimated underwriting 
discount and offering expenses payable by the Company) and the application of 
the estimated net proceeds therefrom, the Company's pro forma as adjusted net 
tangible book value at September 30, 1996 would have been approximately $29.7 
million, or $4.41 share. This represents an immediate increase in pro forma 
net tangible book value of $3.90 per share to the existing stockholders and 
an immediate dilution in pro forma net tangible book value of $10.59 per 
share to new investors. The following table illustrates this per share 
dilution:

(1) If all options to purchase Common Stock outstanding as of September 30, 
    1996 with exercise prices less than the assumed initial public offering 
    price of $15.00 per share were to be exercised, the pro forma as adjusted 
    net tangible book value after this offering would be $4.26 per share and 
    the dilution per share in pro forma net tangible book value to new 
    investors in this offering would be $10.74 per share. 

(2) Includes 330,150 shares of Common Stock issuable upon conversion of the 
    minority interest in limited liability company into shares of Common 
    Stock of the Company upon the closing of this offering. 

(3) Sales by the Selling Stockholder of 750,000 shares in this offering will 
    reduce the number of shares held by existing stockholders to 3,982,150, 
    or approximately 59.2%, and will increase the number of shares held by 
    new investors to 2,750,000, or approximately 40.8%, of the total number 
    of shares of Common Stock to be outstanding after the offering.

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

   The following discussion and analysis should be read in conjunction with 
the Consolidated Financial Statements and related Notes contained elsewhere 
in this Prospectus. 

OVERVIEW 

   The Company is a CRO providing a broad range of integrated product 
development services on a global basis to its clients in the pharmaceutical, 
biotechnology and medical device industries. The Company's services include 
centralized diagnostic testing, clinical trial management, clinical data 
management, biostatistical analysis, Phase I clinical research, health care 
economics and outcomes research and regulatory affairs services. 

   The Company's diagnostic service contracts are on a fee-for-service basis 
and have terms from one month to two years. A portion of the Company's fee 
typically is paid upon contract execution as a non-refundable up-front 
payment, with the remaining amounts billed monthly. Clinical research service 
contracts generally are fixed priced, with certain variable components, and 
range in duration from a few months to two years. A portion of the Company's 
fee typically is paid upon contract execution as a non-refundable up-front 
payment, with the balance billed in accordance with contract terms. The 
Company's contracts generally may be terminated with or without cause on 30 
to 90 days notice. Clients terminate or delay contracts for a variety of 
reasons, including, among others, the failure of products being tested to 
satisfy safety or efficacy requirements; unexpected or undesired clinical 
results of the product; the client's decision to forego a particular study; 
insufficient patient enrollment or investigator recruitment; and production 
problems resulting in shortages of required clinical supplies. In the event 
of termination, the Company typically is entitled to all sums owed for work 
performed through the notice of termination, all costs associated with 
termination of the study, and the unamortized portion of any non-refundable 
up-front payments. 

   Revenues from diagnostic service contracts generally are recognized on a 
per procedure basis as the work is performed. Revenues from clinical research 
service contracts generally are recognized on a percentage of completion 
basis as work is performed. For the nine months ended September 30, 1996 and 
1995, the diagnostic services revenues represented 82.4% and 65.1%, 
respectively, of total net revenues. The Company regularly subcontracts with 
third-party investigators in connection with clinical trials and with other 
third-party providers for 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 revenues. Since reimbursed costs may 
vary significantly from contract to contract and are not meaningful for 
analyzing trends in revenues, they are included in gross revenues but 
excluded from net revenues. Consistent with industry practice, the Company 
considers net revenues its primary measure of growth. The Company has had, 
and expects to continue to have, certain clients from which at least 10% of 
the Company's overall revenue is generated. The Company believes that such 
concentration of business is not uncommon in the CRO industry. 

   The Company has experienced significant growth through internal expansion, 
reflecting an expansion of the Company's client base, additional services 
offered by the Company and an increase in the number and size of projects 
under management. Net revenues grew from $9.0 million for the nine months 
ended September 30, 1995 to $11.6 million for the nine months ended September 
30, 1996. 

   The Company's backlog consists of anticipated net revenues from work under 
letters of intent and contracts that have been signed but not yet completed. 
At October 31, 1996, backlog was approximately $14.7 million. The Company 
believes that its backlog as of any date is not necessarily a meaningful 
predictor of future results and no assurance can be given that the Company 
will be able to fully realize all of its backlog as net revenues. See 
"Business -- Backlog." 

   The Company conducts operations on a global basis, with offices in the 
United States and the United Kingdom. For 1993, 1994, 1995 and the nine 
months ended September 30, 1996, the Company's non-U.S. net revenues 
represented 13.5%, 17.0%, 9.8% and 15.8%, respectively, of total net 
revenues. 


                                       16
<PAGE>


   Contracts between the Company's international division and its clients 
generally are denominated in Pounds Sterling. Because substantially all of 
the international division's expenses are paid and payments are received in 
Pounds Sterling, its earnings are not materially affected by fluctuations in 
the exchange rates. However, the Company's financial statements are 
denominated in U.S. dollars and, accordingly, changes in the exchange rate 
between foreign currencies and the dollar do affect the Company's financial 
results. Cumulative adjustments from translating the international division's 
financial statements have been immaterial and, therefore, have been charged 
to income as incurred. 


RESULTS OF OPERATIONS 


   The following table sets forth for the periods indicated certain financial 
data as a percentage of net revenues. The trends illustrated in the following 
table may not be indicative of future results.

NINE MONTHS ENDED SEPTEMBER 30, 1996 AND SEPTEMBER 30, 1995 

   Net revenues increased $2.6 million, or 28.9% to $11.6 million for the 
nine months ended September 30, 1996, compared to the nine months ended 
September 30, 1995. The increase was directly attributable to a significant 
increase in the volume of diagnostic services. Diagnostic services revenues 
increased $4.0 million or 71.9% for the nine months ended September 30, 1996, 
compared to the same period in the prior year, and include an increase of 
$0.9 million in the net revenues of the Company's U.K. subsidiary. Offsetting 
the increase in diagnostic services revenues was a $1.0 million decrease in 
CANDA revenues and a $0.5 million decrease in Phase I clinical trials 
revenues. The decrease in CANDA revenues was due to the decrease in the level 
of new contract signings caused by the Company's larger pharmaceutical 
clients' ability to perform such services in-house. The Company believes that 
the decrease in Phase I revenues primarily was caused by a delay in the 
commencement of domestic Phase I trials in 1996 as a result of certain 
consolidations occuring in the pharmaceutical industry. 

   Direct costs increased $1.8 million, or 64.3%, to $4.6 million for the 
nine months ended September 30, 1996, compared to the nine months ended 
September 30, 1995. As a percentage of net revenues, direct costs increased 
to 39.8% in 1996, compared to 31.1% in 1995. The increase primarily was 
attributable to increased consulting fees paid to the Company's President in 
connection with medical interpretations for diagnostic tests, in addition to 
general increases in connection with the increase in diagnostic services. The 
consulting fees for medical interpretations increased from $0.6 million in 
1995 to $1.5 million in 1996. The Company and the President have entered into 
a new consulting agreement that discontinues such variable fees effective 
January 1, 1997. See "Certain Relationships" and Notes 7 and 9 of Notes to 
Consolidated Financial Statements. 

   Selling, general and administrative expenses increased $0.5 million, or 
10.9% to $5.1 million for the nine months ended September 30, 1996, compared 
to the nine months ended September 30, 1995. As a percentage of net revenues, 
selling, general and administrative expenses decreased from 51.1% in 1995 to 
43.7% in 1996. The 

                                       17
<PAGE>

dollar increase resulted from additional costs, primarily payroll, required 
to build the clinical trials management business. The reduction as a 
percentage of net revenues was due to the relatively fixed nature of the 
expenses, the Company's focus on monitoring support costs and efficiencies 
gained through increased volume. 

   Depreciation and amortization decreased $0.2 million, or 25.0%, to $0.6 
million for the nine months ended September 30, 1996, compared to the nine 
months ended September 30, 1995. As a percentage of net revenues, 
depreciation and amortization decreased from 8.7% in 1995 to 4.8% in 1996. 
The decrease primarily was the result of the Company's continuing transition 
from more expensive mainframe computers to less expensive personal and 
server-based computers. 

   The Company's effective income tax rate for the nine months ended 
September 30, 1996 was 43.1%, compared to 39.7% for the nine months ended 
September 30, 1995. The rate increase primarily was a result of a one-time 
state tax benefit in 1995 in connection with a change in tax law that 
reinstated the net operating loss carryforward provisions of that state, 
enabling the Company to utilize a suspended carryforward from 1993. 

YEAR ENDED DECEMBER 31, 1995 AND 1994 

   Net revenues decreased $0.8 million, or 6.2%, to $12.1 million for the year
ended December 31, 1995, compared to the year ended December 31, 1994. The
decrease primarily was attributable to a decrease in the Company's CANDA
revenues, partially offset by an increase in the Company's Phase I clinical
testing revenues. CANDA revenues decreased $1.5 million from 1994 due to a
decrease in the level of new contract signings caused by the Company's larger
pharmaceutical clients' ability to perform such services in-house. Diagnostic
services revenues were relatively flat in 1995 compared to 1994, with domestic
revenues increasing $0.9 million, and international revenues decreasing $1.1
million. The increase in domestic diagnostic services revenues was due to an
increase in both the volume and the pricing of diagnostic services. The decrease
in international diagnostic services revenues primarily was the result of two
major project cancellations due to unexpected clinical results. Diagnostic
services revenues in 1995 include $1.2 million of the remaining unamortized
non-refundable up-front payments on certain canceled studies, including $0.2
million at the Company's U.K. subsidiary.

   Direct costs increased $0.6 million, or 17.1%, to $4.1 million for the 
year ended December 31, 1995, compared to the year ended December 31, 1994. 
As a percentage of net revenues, direct costs increased to 34.2% in 1995 from 
26.9% in 1994. The increase was primarily attributable to additional costs 
related to the volume increase at the Phase I clinical research unit, in 
addition to increased consulting fees paid to the Company's President in 
connection with medical interpretations for diagnostic tests. Such consulting 
fees increased from $0.5 million in 1994 to $0.8 million in 1995. See 
"Certain Relationships" and Notes 7 and 9 of Notes to Consolidated Financial 
Statements. 

   Selling, general and administrative expenses decreased $0.8 million, or 
11.1%, to $6.4 million for the year ended December 31, 1995, compared to the 
year ended December 31, 1994. As a percentage of net revenues, selling, 
general and administrative expenses decreased to 52.8% in 1995 from 56.1% in 
1994. The decrease resulted primarily from the decrease in management and 
administrative expenses related to CANDA services as the Company reacted to 
the reduction in its CANDA business. 

   Depreciation and amortization decreased $.2 million, or 16.7%, to $1.0 
million for the year ended December 31, 1995, compared to the year ended 
December 31, 1994. As a percentage of net revenues, depreciation and 
amortization decreased to 8.4% in 1995 from 9.3% in 1994. The decrease 
primarily was the result of the Company's transition from more expensive 
mainframe computers to less expensive personal and server-based computers. 

   The Company's effective income tax rate for the year ended December 31, 
1995 was 43.2%, compared to 41.7% for the year ended December 31, 1994. The 
rate increase in 1995 primarily was the result of the U.K. subsidiary's loss, 
partially offset by a one-time state tax benefit in connection with a change 
in tax law that reinstated the net operating loss carryforward provisions of 
that state, allowing the Company to utilize a suspended carryforward from 
1993. 


                                       18
<PAGE>

YEAR ENDED DECEMBER 31, 1994 AND 1993 

   Net revenues increased $2.7 million, or 26.5%, to $12.9 million for the 
year ended December 31, 1994, compared to the year ended December 31, 1993. 
The increase primarily was attributable to the increased volume of both 
domestic and international diagnostic services, in addition to 1994 being the 
first full year of operation of the Phase I clinical research unit. 

   Direct costs increased $1.1 million, or 45.8%, to $3.5 million for the year
ended December 31, 1994, compared to the year ended December 31, 1993. As a
percentage of net revenues, direct costs increased to 26.9% in 1994 from 23.7%
in 1993. The increase reflects the increased volume at the Phase I clinical
research unit and the increased volume of diagnostic testing services, in
addition to increased consulting fees paid to the Company's President in
connection with medical interpretations for diagnostic tests. Such consulting
fees increased less than $0.1 million in 1993 to $0.5 million in 1994. See
"Certain Relationships" and Notes 7 and 9 of Notes to Consolidated Financial
Statements.

   Selling, general and administrative expenses remained relatively flat at $7.2
million for the year ended December 31, 1994, compared to the year ended
December 31, 1993. However, as a percentage of net revenues, selling, general
and administrative expenses decreased to 56.1% in 1994 from 71.0% in 1993, as
the Company gained efficiencies through increased volume. General and
administrative payroll increased $0.7 million as the Company continued to build
infrastructure to support its growth. This increase was offset by a $0.6 million
decrease in marketing and advertising expenses related to the Company's 1993
launch of a clinical data management product and the opening of its new
corporate headquarters and Phase I clinical research unit.

   Depreciation and amortization increased $0.4 million, or 50.0%, to $1.2 
million for the year ended December 31, 1994, compared to the year ended 
December 31, 1993. As a percentage of net revenues, depreciation and 
amortization increased to 9.3% in 1994 from 7.7% in 1993. The increase 
primarily was the result of additional property and equipment purchased 
during 1993 and early 1994 to support the Company's new corporate 
headquarters and the general increase in business. In addition, the Company 
opened its clinical research unit and clinical laboratory in 1994. 

   The Company's effective income tax rate for the year ended December 31, 
1994 was 41.7%, compared to 28.0% for the year ended December 31, 1993. The 
rate increase in 1994 was primarily the result of the Company not recording a 
state tax benefit on its domestic operating loss in 1993 as state tax law did 
not provide for loss carryforwards or carrybacks. 

QUARTERLY RESULTS 

   The Company's quarterly operating results have been, and are expected to 
continue to be, subject to fluctuations, depending on factors such as the 
commencement, completion or cancellation of large contracts, the mix of 
contract services, the progress of ongoing contracts, the timing of start-up 
expenses for new offices and the introduction of new products and services. 
Because a large percentage of the Company's operating costs are relatively 
fixed in the short term, variations in the timing and progress of large 
contracts could have a material adverse effect on quarterly results. The 
Company believes that comparisons of its quarterly financial results are not 
necessarily meaningful and should not be relied upon as an indication of 
future performance. See "Risk Factors -- Variation in Quarterly Operating 
Results; Seasonality."

LIQUIDITY AND CAPITAL RESOURCES 

   The CRO industry generally is not capital intensive. The Company's 
principal cash needs relate to funding receivables as client payments 
generally lag 45 to 75 days after the invoice date. The Company historically 
has funded the increase in receivables through cash generated from 
operations. 

   For the nine months ended September 30, 1996, the Company's operations 
generated $1.3 million in cash, primarily related to the Company's net 
income. The increase in accounts receivable of $0.9 million for this period 
was generally offset by an increase in accounts payable and accrued expenses 
and other working capital changes. At September 30, 1996, the Company had 
cash and cash equivalents of $0.5 million and working capital of $2.1 
million. For the year ended December 31, 1995, the Company's operations used 
$0.8 million of cash, primarily attributable to a $1.3 million decrease in 
deferred revenues, as 1995 contract signings did not include significant 
up-front payments, partially offset by the Company's net income for the 
period and other changes in working capital accounts. 

                                       20
<PAGE>

   The Company has a $1.0 million Revolving Credit Facility to be used for
working capital purposes at the Company's discretion, which is collateralized by
substantially all of the assets of the Company. Borrowings under the line are
limited to 60% of eligible accounts receivable, as defined. Interest on any
outstanding portion of the line is at the bank's prime lending rate plus 0.5%
(8.75% at September 30, 1996). The line expires June 30, 1997, and is renewable
annually thereafter. The Company had no outstanding borrowings under the line as
of September 30, 1996. The line contains certain financial and operational
covenants, including minimum levels of tangible net worth and working capital
and limitations on sales of capital stock, acquisitions of other entities, loans
to related parties, dividend payments, sale leaseback transactions, types of
investments and lease payments. In November 1996, the Company received a
commitment from its bank to increase the line to $5.0 million and to change the
covenants to permit this offering. This commitment is subject to typical
conditions.

   The Company has no long-term debt or material long-term obligations other 
than its real property leases. See "Business -- Facilities" and Note 9 of 
Notes to Consolidated Financial Statements. The Company currently is 
budgeting approximately $3.0 million for capital expenditures in 1997. 

   The Company expects existing cash and cash equivalents, cash flow from 
operations, the net proceeds from this offering and borrowings under its line 
of credit will be sufficient to meet its foreseeable cash needs for at least 
the next two years. Although the Company presently is not a party to any 
acquisition agreements or similar arrangements, there may be acquisitions or 
other growth opportunities that require additional external financing, and 
the Company may from time to time seek to obtain additional funds from public 
or private issuances of equity or debt securities. There can be no assurance 
that such financings will be available on terms acceptable to the Company. 

   The Company historically has made distributions to UM, its principal 
stockholder, and has committed to pay distributions of $450,000 to UM in the 
fourth quarter of 1996. Subsequent to this offering, the Company does not 
anticipate paying any cash dividends in the foreseeable future and will not 
make further distributions to UM. The Company currently intends to retain 
future earnings to fund the growth of its business. See "Dividend Policy."

                                   BUSINESS 

GENERAL 

   Premier Research Worldwide, Ltd. (the "Company") is a clinical research 
organization ("CRO") providing a broad range of integrated product 
development services to its clients in the pharmaceutical, biotechnology and 
medical device industries. The Company complements the research and 
development departments of its clients by offering high quality clinical 
research services on an as-needed basis, thereby providing a variable cost 
alternative to certain fixed costs typically associated with internal product 
development. Over the last three years, the Company has built a base of over 
100 clients, including 23 of the 25 largest pharmaceutical companies in the 
world. In the first nine months of 1996, the Company performed services under 
96 contracts for 62 clients. The Company's services include centralized 
diagnostic testing, clinical trial management, clinical data management, 
biostatistical analysis, Phase I clinical research, health care economics and 
outcomes research and regulatory affairs services. 

   Throughout its history, the Company has been an innovator in the use of 
new technologies that speed product development and regulatory review. For 
example, the Company created and filed the first computer-assisted new drug 
application ("CANDA") with the United States Food & Drug Administration 
("FDA"). The Company has designed its technology to simplify and make more 
efficient the collection, transfer, analysis and preparation of clinical 
trial data. The Company believes that its proprietary technology links all 
facets of clinical development, produces cost advantages, facilitates 
superior levels of service, improves the quality of clinical research and 
enhances the Company's global capabilities. 

   All of the Company's services are designed to help clients reduce their 
product development time in a cost-effective manner. In 1977 the Company's 
predecessor, Cardio Data Systems, began providing diagnostic testing services 
used to evaluate the safety and efficacy of new drugs. Today, the Company 
provides these services, which include electrocardiograms ("ECGs"), Holter 
monitoring, pulmonary function testing, blood and urine sampling, and other 
tests, on a centralized basis. To take advantage of the potential synergies 
and cross-selling opportunities with its centralized diagnostic testing 
services, the Company added clinical trial management capabilities in 
September 1995 by forming a limited liability company with PREMIER, Inc., 
which is owned 65% by the Company. Upon the closing of this offering, 
PREMIER, Inc.'s minority interest in this limited liability company will be 
converted into 330,150 shares of Common Stock of the Company. Although a 
substantial majority of the Company's net revenues is still derived from 
centralized diagnostic testing services, the Company today has the capacity 
to provide the full range of CRO services on a global basis. 


INDUSTRY BACKGROUND 


   CROs provide product development services to the pharmaceutical, 
biotechnology and medical device industries, and derive substantially all of 
their revenues from the research and development expenditures of these 
industries. The CRO industry provides a comprehensive range of product 
development services, including study design, clinical trial management, data 
collection, biostatistical analysis, diagnostic testing and regulatory 
services. All these clinical trials services are subject to applicable 
government regulations in jurisdictions where the services are provided. 

   The CRO industry is highly fragmented, with participants ranging from 
several hundred small, limited-service providers to a few large, 
full-service CROs with global capabilities. Although there are few barriers 
to entry for small, limited-service providers, the Company believes that 
there are significant barriers to becoming a full-service CRO with global 
capabilities. Some of these barriers include the high fixed personnel costs 
required to develop broad therapeutic capabilities, the need for 
sophisticated management information systems, expertise and technology to 
manage complex clinical trials, the ability to access investigators and 
specific patient populations in sufficient numbers and the infrastructure 
necessary to serve the global needs of clients. 


   As a result of competitive pressures and economies of scale, the CRO 
industry is consolidating. Mergers and acquisitions have resulted in the 
emergence of a few large, full-service CROs with the capital, technical and 
financial resources to conduct all phases of clinical trials on behalf of 
pharmaceutical, biotechnology and medical device companies. The Company 
believes that industry trends favor those CROs able to provide a full range 
of services. 

                                       22
<PAGE>


   Diagnostic testing services form a part of most new drug studies. While 
most CROs sub-contract these services, the Company directly provides a full 
array of centralized diagnostic testing services. The Company believes that 
the ability to provide a broad range of centralized diagnostic testing 
services will become an important factor in competing as a full-service CRO. 


INDUSTRY TRENDS 

   The global pharmaceutical and biotechnology industries spent an estimated 
$35 billion in 1995 on research and development, of which the Company 
estimates $20 billion was spent on the type of services offered by the 
Company. Of this amount, approximately $2.5 billion was outsourced to CROs. 
The Company believes that the following trends will lead to increased 
outsourcing of drug and device development activities by pharmaceutical, 
biotechnology and medical device companies: 

CLIENT DEMAND FOR FASTER PRODUCT DEVELOPMENT 


   Pharmaceutical, biotechnology and medical device companies face increased 
pressure to bring innovative, patent-protected products to market in the 
shortest possible time, while following good clinical practices and adhering 
to applicable government regulations. Reducing product development time 
maximizes the client's potential period of marketing exclusivity and, in 
turn, the potential economic returns for new products. The Company believes 
that CROs able to improve the speed and quality of product development, 
through appropriate clinical, technological and organizational expertise, are 
able to provide more effective product development services than most 
pharmaceutical, biotechnology or medical device companies could perform 
internally. The Company believes that the practice of some pharmaceutical, 
biotechnology or medical device companies to contract with full-service CROs, 
rather than separately contracting specific phases of product development to 
several different CROs, also may result in faster overall development times. 
In addition, the Company believes that its clients increasingly recognize 
that the use of technology to produce clinical databases designed to 
facilitate regulatory review reduces product development and regulatory 
review time. 


COST CONTAINMENT PRESSURES 


   Cost containment pressures on pharmaceutical and medical device companies 
arising from market acceptance of generic drugs, managed care pressures to 
reduce prices, the development of large purchasing alliances and the use of 
formulary restrictions has led to increased scrutiny of product development 
expenses. This cost containment pressure has prompted many pharmaceutical and 
medical device companies to reduce staffing levels, to centralize research 
and development and to increase outsourcing to CROs. In addition, the Company 
believes that the increased need to differentiate products and to generate 
support for product pricing will aid the growth of pharmacoeconomic and 
outcomes research, both for products under development and products already 
on the market. 

   The pharmaceutical and medical device industries are consolidating in 
response to the need for cost reductions. Once consolidated, many 
pharmaceutical and medical device companies outsource to CROs in an effort to 
reduce the high fixed personnel cost associated with internal drug 
development. At the same time, the Company believes that pharmaceutical and 
medical device companies will continue to develop new products that represent 
potential sources of new business for the Company and other CROs. 


INCREASINGLY COMPLEX AND STRINGENT REGULATIONS 


   Increasingly complex and stringent regulatory requirements have added to 
the volume of data required for regulatory filings. The pharmaceutical and 
biotechnology industries are increasingly outsourcing to CROs to manage the 
added work loads created by these regulatory requirements. More stringent 
regulatory requirements are being applied to medical devices as well. The 
Company believes that this trend will increase the volume of data required 
for device regulatory filings and escalate the demand for data collection and 
analysis services during the device development process, creating additional 
opportunities for CROs. 

DEVELOPMENT OF DRUGS FOR COMPLEX DISEASES 


   The development of an increasing number of drugs targeted at complex 
chronic diseases, such as Alzheimer's disease, and drugs that address 
specific patient populations, such as stroke patients, has increased 

                                       23
<PAGE>

the need for specialized clinical trial management and patient recruitment 
services. The Company believes that this increased complexity will result in 
greater outsourcing by pharmaceutical, biotechnology and medical device 
companies to CROs with particular expertise in certain therapeutic areas and 
with the ability to access these specific populations. 

BIOTECHNOLOGY INDUSTRY GROWTH 


   In the last decade, the United States biotechnology industry has grown 
rapidly and is developing an increasing number of the new products submitted 
for regulatory approval. From 1989 to 1995, the number of biotechnology 
products in clinical trials rose from 80 to over 450, an annual compounded 
growth rate of approximately 35%. Many biotechnology companies do not have 
the necessary staff, expertise or financial resources to conduct clinical 
trials on their own, and may not believe that it is in their strategic 
interest to create such capabilities. The Company believes that biotechnology 
companies provide growth opportunities for CROs. In addition, the 
biotechnology industry is conducting more clinical trials outside the United 
States, benefiting CROs with international capabilities. 


GLOBALIZATION OF CLINICAL RESEARCH AND DEVELOPMENT 


   Pharmaceutical, biotechnology and medical device companies are 
increasingly attempting to expand the market for new products by pursuing 
regulatory approvals in multiple countries simultaneously, rather than 
sequentially as they have in the past. Expanding the market for a product and 
accelerating regulatory review times are particularly important to these 
companies because of limited patent lives and the high development costs of 
new products. To respond to these pressures and to gain access to the global 
marketplace, pharmaceutical, biotechnology and medical device companies are 
increasingly outsourcing to CROs that have full-service, international 
capabilities and that are able to coordinate concurrent regulatory filings. 

NEED FOR SOPHISTICATED DATA MANAGEMENT 

   During a clinical trial, clients often receive data from multiple sources 
in a variety of incompatible formats. To make cost effective, real-time 
product development decisions using this data, it is necessary to have 
sophisticated data management systems that can more easily analyze the data. 
As a result, both clients and government regulators seek real-time, 
interactive access to clinical data. 

   In addition to increasing the volume of data required for filings, 
regulatory agencies are also requesting data in electronic form, permitting 
more direct independent analysis. For example, the FDA has issued guidelines 
encouraging the use of computer-assisted filings in an effort to expedite the 
review process. Additionally, the need for pharmacoeconomic and outcomes 
research increases the requirements for data. The Company believes that 
pharmaceutical, biotechnology and medical device companies may outsource to 
CROs with sophisticated data management capabilities to reduce costs and to 
access their technological expertise. 


THE COMPANY'S STRATEGY 


   The Company's objective is to accelerate its clients' product development 
timelines. The Company's strategies for achieving this objective include: 


USE INNOVATIVE TECHNOLOGY TO ACCELERATE AND IMPROVE PRODUCT DEVELOPMENT 


   The Company believes that its proprietary technology links all facets of 
clinical development, produces cost advantages, facilitates superior levels 
of service, improves the quality of clinical research and enhances the 
Company's global capabilities. The Company has specifically designed its 
technology for use by medical personnel rather than information technology 
specialists. The Company's technology enables it to create and continually 
update its clinical databases as trials progress and allows for interactive 
review of data by its clients and governmental regulators. See "Technology." 


PROVIDE COMPREHENSIVE PRODUCT DEVELOPMENT SERVICES 


   The Company believes that CROs able to offer a full range of product 
development services will have a competitive advantage because a single 
provider increases the speed and accuracy of clinical data collection through 
compatible systems and uniform data formats. The Company provides a full 
array of clinical research 


                                       24
<PAGE>


services, including, centralized diagnostic testing services, clinical trial 
management, clinical data management, biostatistical analysis, Phase I 
clinical research, health care economics and outcomes research and regulatory 
affairs services. The Company believes that offering a full range of 
centralized diagnostic services, in addition to its other clinical research 
services, provides an additional competitive advantage. 


EXPAND CAPACITY FOR GLOBAL PRODUCT DEVELOPMENT SERVICES 


   The Company believes that the ability to provide global product 
development services enhances its ability to compete for large multi-national 
business. The Company has an international presence in diagnostic services 
and has supported trials in 32 countries out of its Philadelphia, PA and 
Peterborough, U.K. offices. Using this experience and infrastructure, the 
Company is expanding its clinical trial management and clinical data 
management services to areas outside of the United States. 


DEVELOP ITS STRATEGIC RELATIONSHIP WITH PREMIER, INC. 


   The Company intends to leverage its strategic relationship with PREMIER, 
Inc., the largest voluntary alliance of hospitals in the United States. In 
1996, PREMIER, Inc. expects to negotiate, on behalf of the alliance, group 
purchases of approximately $10 billion of medical devices, supplies and 
pharmaceuticals. PREMIER, Inc. actively aids the Company in marketing its 
services to the numerous pharmaceutical, biotechnology and medical device 
companies that sell products and services to the alliance. In addition, the 
Company believes that its access to PREMIER, Inc.'s patient and physician 
databases provides a competitive advantage for patient and investigator 
recruitment. PREMIER, Inc. is developing a large trial management 
organization, for which the Company will be the exclusive CRO. The Company 
and PREMIER, Inc. also have begun working together to develop an adverse 
event reporting system and a drug use information system, and the Company 
plans to expand this activity to include such services to PREMIER, Inc. 
members and other health systems. See "Relationship with PREMIER, Inc." 


PURSUE STRATEGIC ACQUISITIONS 


   The Company plans to pursue strategic acquisitions of related businesses 
and selected CROs. Acquisition candidates must provide opportunities for 
innovation and growth and include businesses that provide complementary 
services, expand the Company's geographic presence, provide new therapeutic 
expertise, or have complementary client bases. 


COMPANY SERVICES 


   The Company's historic business has been the provision of centralized 
diagnostic testing services, which continues to account for a substantial 
majority of the Company's net revenues. The Company added clinical trial 
management capabilities in September 1995 when it formed a limited liability 
company with PREMIER, Inc., owned 65% by the Company. Upon the closing of 
this offering, PREMIER, Inc.'s interest in this limited liability company 
will convert into 330,150 shares of the Company's Common Stock. Today, the 
Company provides a full range of clinical research services. The Company's 
services include centralized diagnostic testing services, clinical trial 
management, clinical data management, biostatistical services, Phase I 
clinical research, health care economics and outcomes research and regulatory 
affairs services, both in the United States and internationally. 

CENTRALIZED DIAGNOSTIC TESTING SERVICES 

   Diagnostic tests are employed in clinical trials to measure the effect of 
the product on certain body organs and systems, to determine the product's 
safety and/or efficacy. Diagnostic testing services provided by the Company 
include a variety of diagnostic tests, such as ECGs, Holter monitoring and 
clinical laboratory services. These services, which the Company provides on a 
centralized basis, are part of most new drug studies. In most cases, the ECG 
and transtelephonic monitoring strips, Holter monitoring tapes, imaging and 
pulmonary function computer disks and blood and urine samples are delivered 
to the Company, which the Company then analyzes or interprets. The Company 
provides a broad array of centralized diagnostic testing services, including 
the following: 


                                       25
<PAGE>


   12-lead Electrocardiography. The ECG provides an electronic map of the 
heart's rhythm and structure, and typically is performed in most clinical 
trials. ECG strips are measured by the Company's analysts utilizing a 
digitizing system, and are then interpreted by a Board-certified 
cardiologist. 

   Holter Monitoring. Holter monitoring is a 24 hour continuous ECG recording 
of the heart's rhythm on a cassette tape. The Company has provided Holter 
monitoring services since 1977. 

   Transtelephonic Monitoring (TTM). TTM measures the electrical activity of 
the heart, typically for 5 to 30 seconds. This data is transmitted over 
telephone lines by patients carrying a self-activated transmitting device. 
This test typically is utilized in trials seeking to identify symptomatic 
heart rhythm events. 

   Pulmonary Function Testing (PFT). PFT measures the lungs' capacity and 
function by having the patient breathe into a spirometer. 

   Diagnostic Imaging. This service is used in all clinical imaging 
modalities, including standard radiography (e.g., x-rays), contrast-enhanced 
radiography (e.g., angiography, studies of the gastrointestinal tract), 
computed techniques (including CT scanning and MRI), nuclear medicine 
techniques and ultrasonography to determine or confirm the condition of a 
patient. 


   Clinical Laboratory Services. The Company performs centralized reference 
testing of blood and urine samples for multi-center drug trials and in 
support of the Company's Phase I clinical research unit. 


CLINICAL TRIAL MANAGEMENT SERVICES 

   The Company offers complete services for the design, performance and 
management of clinical trial programs. The results of clinical trials form 
the basis on which regulatory approval is granted for pharmaceutical and 
biotechnology products and medical devices. The Company's multi-disciplinary 
clinical research group and extensive network of consultants examine a 
product's pre-clinical and clinical data to design protocols that will 
evaluate the product's safety and efficacy. The Company can then manage every 
aspect of clinical trials, including protocol and database design, site and 
investigator recruitment, regulatory initiation, patient enrollment, study 
monitoring and data collection, medical services and report writing. 

   The Company's clinical trial management services include the following: 


   Study Protocol Design. The protocol defines the medical issues the study 
seeks to examine and the statistical tests that will be conducted to 
determine whether the product is safe and effective or, in some 
pharmacoeconomic trials, whether it is cost-effective. Detailed in the 
protocol are: (i) the number and type of clinical, laboratory and outcomes 
measures that are to be tracked and analyzed, (ii) the number of patients 
required to produce a statistically valid result, (iii) the period of time 
over which the patients must be tracked and (iv) the dosage and frequency of 
drug administration or the program of use of the relevant device. 


   Site and Investigator Recruitment. The drug or device being tested is 
administered to patients by physicians (investigators), at hospitals, clinics 
or other locations (sites). Potential investigators are identified by a 
number of means. In some cases, the sponsor has pre-selected investigators 
with whom it wishes to work. The CRO generally solicits the investigator's 
participation in the study. Each trial's success depends on the successful 
identification and recruitment of investigators with an adequate base of 
patients who meet the requirements of the study protocol. The Company has a 
database of several thousand investigators, both within and outside the 
PREMIER, Inc. alliance of hospitals. Access to this data allows the Company 
to readily identify the sites and investigators able to provide the requisite 
patient population. 

   Patient Enrollment. Investigators find and enroll patients suitable for 
each study according to the protocol. The speed with which trials can be 
completed is significantly affected by the rate at which patients are 
enrolled. Inability to recruit a sufficient number of patients in a timely 
manner is a recurring problem and one of the most frequent causes of clinical 
trial delays, as well as a major source of cost overruns for the sponsor. The 
Company believes that its affiliation with PREMIER, Inc. and the resultant 
access to PREMIER, Inc.'s databases should enhance the Company's ability to 
quickly and cost-effectively recruit investigators and patients for clinical 
trials. The Company believes that its access to PREMIER, Inc.'s patient 
databases provides a competitive advantage because it permits the Company to 
identify more precisely exclusion and inclusion criteria, thereby maximizing 
patient recruitment without jeopardizing patient safety. 


                                       26

   Regulatory Services. Each site is required to document compliance with 
regulations governing the conduct of clinical trials, which must be completed 
before a trial can be initiated. The PremierResearcho CTIMS (clinical trial 
information management system) facilitates this process by providing 
real-time tracking of the status of all relevant documents to the Company and 
to the client. 

   Study Monitoring and Data Collection. As patients are examined and tests 
are conducted in accordance with the study protocol, data are recorded on 
customized case report forms ("CRFs") and laboratory reports. Traditionally, 
these data are assessed at the study site by specially trained clinical 
research associates, also known as CRAs or monitors. The CRAs compare the 
data to the medical records at the site to reduce the possibility of fraud or 
error. The CRA requires site personnel to correct errors to facilitate 
efficient data entry. CRAs visit sites regularly to ensure that the CRFs are 
completed correctly and that all data specified in the protocol are 
collected. CRFs are reviewed for consistency and accuracy before their data 
are entered into an electronic database. In most CROs, these data are 
manually entered by personnel who are not trained to evaluate the content of 
the data. 

   The Company also offers its clients the PremierResearcho Fax system, which 
can accelerate the completion and collection of accurate CRFs. The 
PremierResearcho Fax system permits a CRF to be filled out by the 
investigating site and faxed to the Company within days of a patient's visit. 
The data from the fax are automatically downloaded into the Company's 
database by means of optical character recognition and the results are 
carefully checked both by computer and by trained clinical research 
personnel. Any errors are compiled and automatically faxed back to the site 
for correction. This process allows a large portion of data errors to be 
identified and corrected within a week of a given patient's visit, as opposed 
to the traditional correction process that typically requires several weeks 
to several months. The Company believes that correcting a large portion of 
the errors as the trial progresses decreases the time and expense of clinical 
data collections and is a significant competitive advantage. 

   Medical Services and Report Writing. During the course of a clinical 
trial, the Company may provide medical research services, including medical 
monitoring of the clinical trials and interpretation of clinical trial 
results. In addition, the statistical analysis of the data collected during a 
trial, together with other clinical data, are included in a final report 
generated for inclusion in a regulatory document. The Company's 
PremierResearcho CARD (computer-assisted research and development) technology 
allows for immediate correction of data and identification of safety and 
efficacy issues that may change the course of the clinical development plan 
or accelerate its timeline. The Company believes that this results in 
improved medical services. 

CLINICAL DATA MANAGEMENT AND BIOSTATISTICAL ANALYSIS 

   The Company has a history of technological innovation in the provision of 
services in drug trials, including creating the first computer-assisted new 
drug application ("CANDA") and creating over sixty CANDAs. The Company 
believes that its technological expertise provides a competitive advantage in 
the provision of clinical data management and biostatistical analysis 
services. 

   Clinical Data Management. The Company's data management professionals 
assist in the design of protocols and CRFs, as well as the development of 
training manuals for investigational staff to ensure that data are collected 
in a systematic format. Once the study protocol has been finalized, CRFs for 
recording the desired information must be developed. Different CRFs may be 
used at different assessment periods during the course of a trial reflecting 
the variety of data collected, and there may be as many as 100 or more CRFs 
for each patient in a given study. The Company's technically trained staff 
format CRFs compatible with the optical character recognition capabilities of 
the Company's PremierResearcho Fax system. CRFs, when utilized with the 
PremierResearcho Fax system, increase the accuracy and reduce the time and 
cost of data processing during the trial. Databases are designed according to 
the analytical specifications of the project and the particular needs of the 
client. The Company provides clients with data listings, data review and 
coding, data entry, database verification and editing and problem data 
resolution. In addition, the Company offers its clients the ability to 
compile the clinical data for an electronic regulatory submission, such as a 
CANDA. 

   Biostatistical Analysis. The Company's biostatistics professionals provide 
biostatistical consulting, database design, data analysis and statistical 
reporting. These professionals develop and review protocols, design 
appropriate analysis plans and design report formats to address the 
objectives of the study protocol and the cli-


                                       27
<PAGE>


ent's individual objectives. The Company's programming staff and 
biostatisticians work together to perform appropriate analyses and produce 
tables, graphs, listings and other applicable displays of trial results. In 
addition, biostatisticians can assist clients in government regulatory 
proceedings and in legal proceedings. 

PHASE I CLINICAL RESEARCH 

   The Company maintains a 28-bed, monitored clinical research unit in which 
it conducts Phase I clinical research studies. This unit focuses on complex 
Phase I trials that require diagnostic testing such as ECG, Holter monitoring 
and similar services. 

HEALTH CARE ECONOMICS AND OUTCOMES RESEARCH 

   In response to the increased need for pharmacoeconomic and outcomes data 
following product approval, the Company plans to offer a variety of health 
information services using its expertise in data collection, acquisition, 
monitoring, and auditing. The Company intends to design and conduct 
pharmacoeconomic, technology assessment, and clinical outcomes studies for 
pharmaceutical clients as well as for PREMIER, Inc. and its affiliated 
hospitals and institutions. PREMIER, Inc. and the Company are developing an 
adverse event reporting system and a drug use information system. The Company 
plans to expand this activity to include such services to PREMIER, Inc. 
members and other health systems. 

REGULATORY AFFAIRS SERVICES 

   The Company provides comprehensive regulatory product registration 
services for pharmaceutical, biotechnology and medical device products in 
North America, including regulatory strategy formulation, document 
preparation and intermediation with the FDA and other regulatory agencies. 
The Company reviews published literature, assesses the scientific background 
of a product and the competitive and regulatory environment, identifies 
deficiencies and defines the steps necessary to obtain registration in the 
most expeditious manner. Through this service, the Company helps its clients 
determine the feasibility of developing a particular product or product line. 


TECHNOLOGY 


   The Company's technology is designed to accelerate product development and 
to improve the quality of clinical research by providing superior data 
handling that facilitates analysis. Its technology is developed for clinical 
research personnel, rather than information technology specialists, enabling 
medical reviewers to make timely and accurate decisions during the product 
development process. The Company's software is available on multiple 
platforms such as Microsoft Windows, Macintosh, and DOS, which facilitates 
integration with the wide variety of systems used by its clients. 

   The Company believes that its technology is attractive to its clients' 
clinical groups, since it includes "user-friendly" tools specifically 
designed for clinical research personnel. The Company believes that this 
provides a competitive advantage, since this group is influential in CRO 
selection. 

   The Company has a history of technological innovation in supporting 
clinical trials, including: 


   o First electronic transfer of centralized diagnostic data, eliminating 
     manual key punching (1979). 

   o First multi-site remote data entry system used by the FDA, partially 
     replacing site monitoring (1984). 


   o First computer-assisted new drug application, shortening the regulatory 
     review process (1985). The Company has since created over 60 full data 
     review CANDAs, which it believes constitutes more CANDAs of this kind 
     than those created by all the other major CROs combined. 

   o First NDA Day, a one day intensive session between the FDA and the 
     product's sponsor using the interactive features and real-time data 
     query capabilities of the CANDA (1988). 

   o First interactive CANDA, providing for the interactive review of 
     clinical data by the FDA, further accelerating the regulatory review 
     process (1993). 

                                       28

   The Company's technology includes: 

   PremierResearcho Navigator. Navigator is the Company's proprietary, highly 
interactive software system designed specifically for the review, analysis 
and submission of clinical data in the new drug or device application 
process. The Company's role in the first CANDA submission, the first 
interactive CANDA and the first NDA Day, which are described above, are 
examples of uses of the technology that has evolved into the Navigator. 
Navigator is designed to allow medical and regulatory personnel to 
interactively review and analyze research data. It is a "user-friendly" 
software that permits medical personnel to: subset data; better analyze and 
understand clinical trial results, including adverse events and 
identification of outliers; graphically display clinical research data; and 
respond more quickly to regulatory review questions. The Company believes 
that use of its Navigator system speeds both the product development and 
regulatory review process, which allows the client to prioritize, change or 
potentially terminate development of the product. 

   The Company markets the Navigator system for single clinical studies or 
single laboratory datasets under the name PremierResearcho CARD 
(computer-assisted research and development). Immediate review of clinical 
information to detect errors in trial conduct is possible with 
PremierResearcho CARD, allowing for rapid correction of data and 
identification of safety and efficacy issues that may change the course of 
the clinical development plan or accelerate its timeline. 

   The Company markets the Navigator system for electronic regulatory 
submissions for pharmaceutical clients under the name PremierResearcho CANDA. 
PremierResearcho CANDA allows for faster and more effective medical review 
and analysis of the submission by the product's sponsor and by regulatory 
authorities than conventional tools. Navigator also may be used for the 
regulatory submission of biologic and medical device clinical data. 

   PremierResearcho Enterprise. Enterprise is a proprietary information 
management system that permits efficient and timely delivery of diagnostic 
and clinical trial data to the user. Enterprise integrates an entire set of 
data from an individual patient in a clinical trial. This information is then 
available for on-line review by project management, diagnostic services and 
clinical research personnel. Enterprise also provides for flexible encoding 
and transfer of the clinical information to the client, based on standardized 
data specifications or the client's own specifications. The data can be 
provided to the client in a variety of data and media formats, as well as 
bundled with Navigator, to allow for immediate interactive review. The 
Company believes that Enterprise facilitates and speeds product development 
by making it easier for the client to collect, store, retrieve and utilize 
the massive amounts of data traditionally collected in clinical trials. 

   PremierResearcho Fax. This system receives CRFs, electronically enters the 
information into databases, electronically queries the site to correct data 
errors and inconsistencies, and compiles the resultant database for rapid 
export. The Company believes that the PremierResearcho Fax system can 
accelerate the collection and correction of the CRF, which is filled out by 
investigators at a site and faxed to the Company within days of the patient 
visit. The data from the fax is automatically downloaded into the Company's 
database by means of optical character recognition and the results are 
carefully checked by both the computer and trained clinical research 
personnel. Any errors are compiled and automatically faxed back to the site 
for correction. This process allows a large portion of data errors to be 
resolved within a week of a given patient's visit, as opposed to the 
traditional correction process that typically requires several weeks to 
several months. The Company believes that correcting a large portion of 
errors as the trial progresses decreases the time and expense of clinical 
data collection. 

   The Company is in the early stages of developing a remote pen-based data 
entry system that permits two-way interaction between the Company and the 
site (PremierResearcho Pad), and an interactive voice response system for 
automated telephone data entry (PremierResearcho Voice), which will augment 
PremierResearcho Fax. 

   PremierResearcho CTIMS. The Company's proprietary project management 
software, PremierResearcho CTIMS (clinical trial information management 
system), manages the clinical trial process. CTIMS automates many laborious 
tasks of trial management using software modules for various applications. 
These modules allow for regulatory and other document tracking; investigator, 
site and patient recruitment and tracking; CRA monitoring; and contract 
management.

RELATIONSHIP WITH PREMIER, INC. 

   In September 1995, the Company formed a limited liability company with 
PREMIER, Inc., which is owned 65% by the Company, for the provision of 
clinical research services. Upon the closing of this offering, PREMIER, 
Inc.'s interest in the limited liability company will convert into 330,150 
shares of the Company's Common Stock. 

   PREMIER, Inc. is a voluntary healthcare alliance of 1,800 affiliated 
hospitals and institutions which is the result of the merger of the Premier 
Health Alliance, Inc., American Healthcare Systems, Inc. and SunHealth 
Alliance, Inc. It is the largest voluntary healthcare alliance in the United 
States, representing over 300,000 hospital beds located in all 50 states. 
PREMIER, Inc. negotiated, on behalf of the alliance, group purchases of 
approximately $6 billion of medical devices, supplies and pharmaceuticals in 
1995, and expects to negotiate group purchases of approximately $10 billion 
of such products in 1996. 

   The agreement between PREMIER, Inc. and the Company gives the Company 
access to information about PREMIER, Inc.'s pharmaceutical contacts as well 
as access to PREMIER, Inc.'s databases of patients and physicians for use in 
connection with the Company's clinical research studies. The Company, in 
turn, has agreed that PREMIER, Inc.'s affiliated hospitals will be utilized 
as investigator sites for these studies; however, the Company is not 
restricted from using investigator sites outside the PREMIER, Inc. alliance. 

   In addition to these contractual provisions, the Company seeks to leverage 
its strategic relationship with PREMIER, Inc. in the following ways: 

   o PREMIER, Inc. has agreed to introduce the Company to pharmaceutical and 
     device companies that sell or propose to sell products to the alliance, 
     and to include a requirement in all of its drug and device purchase 
     agreements that such companies will consider utilizing the Company's 
     services in their clinical trials. For this purpose, the Company has 
     assigned one salesperson to work exclusively at PREMIER, Inc.'s 
     principal purchasing office and to participate in group purchasing 
     meetings. 

   o PREMIER, Inc., with the assistance of the Company, is developing a large 
     trial management organization ("TMO"), for which the Company will be the 
     exclusive CRO. The TMO will standardize and coordinate investigators, 
     clinical sites and patient recruitment and form a central institutional 
     review board ("IRB"). The Company believes that its involvement with 
     this TMO will facilitate the development of close working relationships 
     with a large nationwide network of investigators, producing improvements 
     in the quality, speed and cost of the clinical development process. 

   o The Company is the only CRO with access to PREMIER, Inc.'s databases. 
     This access permits the Company to independently estimate the available 
     patient population in a given area and to assess whether an individual 
     investigator has direct access to a suitable patient population. Knowing 
     whether a given investigator can supply a sufficient number of patients 
     meeting the inclusion and exclusion criteria of a particular protocol is 
     an important competitive advantage, since patient enrollment is a 
     critical factor in a successful trial. Additionally, the Company will 
     use its access to this database to generate pharmacoeconomic and 
     outcomes data for its clients. 

   o The Company and PREMIER, Inc. are collaborating on the development of an 
     adverse events reporting system and drug use information system. It is 
     expected that these systems will be used by PREMIER, Inc.'s affiliated 
     hospitals and subsequently may be marketed to other hospitals. 

   The Company believes that PREMIER, Inc. benefits from its relationship 
with the Company in a variety of ways. The Company's commitment to utilize 
PREMIER, Inc.'s affiliated hospitals in its studies may constitute an 
incentive for hospitals to join the PREMIER, Inc. alliance, due to both the 
fees received by the hospital and the prestige of being involved in clinical 
research. The statistical and data management services being developed by the 
Company also are expected to provide helpful information and expertise to 
PREMIER, Inc. in making its purchasing decisions. 


SALES AND MARKETING 


   The Company's marketing strategy is to focus on prospective clients whose 
product development projects are complex. The Company's sales staff maintains 
direct contacts and relationships with clients and prospective 


                                       30
<PAGE>


clients. Two senior salespeople with substantial experience in the marketing 
of large trials have recently joined the Company. The Company believes that a 
large percentage of its clients have been referred by others in the industry, 
and its salespeople seek to foster such referrals. 

   The Company believes that its technology is attractive to the clinical 
staff of its clients because of its "user-friendly" tools specifically 
designed for clinical research personnel. The Company believes that this 
provides it with a competitive marketing advantage, since such personnel are 
influential in CRO selection. 

   While the Company seeks new clients, it also attempts to increase repeat 
business with existing clients by meeting high quality and timely performance 
standards and through proactive project management. Approximately 78% of net 
revenues in the first nine months of 1996 were derived from clients for which 
the Company previously has performed services. When the Company increases the 
amount of business with an existing client, both benefit from the 
efficiencies of using proven systems already in place for study conduct and 
data delivery. 

   The Company intends to use its affiliation with PREMIER, Inc. to gain 
access to pharmaceutical, biotechnology and medical device companies that 
sell or propose to sell products to PREMIER, Inc. For this purpose, the 
Company has assigned one salesperson to work exclusively at PREMIER, Inc.'s 
principal purchasing office and to participate in group purchasing meetings 
to directly market the Company's services. 

   The Company uses direct mailings of brochures and marketing materials to 
existing and prospective clients and advertises in trade journals and similar 
publications. The Company also attends and exhibits at selected trade shows 
in the United States and Europe. 


CLIENTS 


   Over the last three years, the Company has provided services to 23 of the 
top 25 pharmaceutical companies in the world as ranked by 1995 research and 
development expenditures. During the first nine months of 1996, 
pharmaceutical companies accounted for approximately 90% of the Company's net 
revenues. In the future, as the Company expands its clinical research 
services, it expects that biotechnology and medical device companies will 
account for a more significant percentage of its net revenues. At September 
30, 1996, the Company was providing services under 96 contracts to 62 
clients, including some of the largest United States, European and Japanese 
pharmaceutical companies. In 1994, two clients represented approximately 
17.0% and 11.5% of the Company's net revenues and in 1995 three clients 
accounted for approximately 15.0%, 12.1% and 10.0% of the Company's net 
revenues. During the first nine months of 1996, three clients accounted for 
approximately 15.3%, 10.5% and 10.4% of the Company's net revenues. The loss 
of any significant client could have a material adverse effect on the 
Company's net revenues. See "Risk Factors -- Dependence on Certain Industries 
and Clients" and "Risk Factors -- Loss or Delay of Contracts." 


BACKLOG 


   Backlog consists of anticipated net revenues from work under letters of 
intent and contracts that have been signed but not yet completed. Once work 
under a contract or letter of intent commences, revenues are generally 
recognized over the life of the contract, which usually lasts for anywhere 
from one month to two years. Backlog excludes anticipated net revenues from 
projects for which the Company has commenced work but for which a definitive 
contract or letter agreement has not been executed. Backlog at October 31, 
1996 was approximately $14.7 million. 

   The Company believes that its backlog as of any date is not necessarily a 
meaningful predictor of future results. Clinical studies under contracts 
included in backlog are subject to termination or delay. Clients terminate or 
delay contracts for a variety of reasons including, among others, the failure 
of products being tested to satisfy safety requirements, unexpected or 
undesirable clinical results of the product, the client's decision to forego 
a particular study, insufficient patient enrollment or investigator 
recruitment or production problems resulting in shortages of the drug. Most 
of the Company's contracts are terminable without cause upon 30 to 90 days 
notice by the client. The Company typically is entitled to keep any advance 
payment and receive certain fees for winding down a study that is terminated 
or delayed and, in some cases, a termination fee. See "Risk Factors -- 
Dependence on Certain Industries and Clients" and "Risk Factors -- Loss or 
Delay of Contracts."

COMPETITION 


   The decision of whether to outsource can place the Company in competition 
with a client's in-house development group. However, once the decision is 
made to outsource, the Company primarily competes against other full service 
CROs and, to a lesser extent, universities and teaching hospitals. Some of 
these competitors have substantially greater capital, technical and other 
resources than the Company. Large CROs with which the Company competes 
include ClinTrials Research, Inc., Covance, Inc., IBAH, Inc., Pharmaceutical 
Product Development, Inc., PAREXEL International Corporation and Quintiles 
Transnational Corporation. CROs generally compete on the basis of experience, 
medical and scientific expertise in specific therapeutic areas, the quality 
of clinical research, 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 clinical research, an 
international presence, financial viability and price. The Company believes 
that it competes favorably in all of these areas. 

   The CRO industry is highly fragmented, with participants ranging from 
several hundred small, limited-service providers to a few large, 
full-service CROs with global operations. The trend toward CRO industry 
consolidation has resulted in heightened competition among the CROs for 
clients and acquisition candidates. In addition, consolidation within the 
pharmaceutical industry, as well as a trend by pharmaceutical companies to 
outsource to fewer CROs, has heightened competition among CROs for contracts 
from that industry. The Company believes major pharmaceutical, biotechnology 
and medical device companies tend to develop preferred provider relationships 
with full-service CROs, effectively excluding smaller CROs from the bidding 
process. The Company may find reduced access to certain potential clients due 
to these arrangements. 


GOVERNMENT REGULATION 


   Human pharmaceutical products, biological products and medical devices are 
subject to rigorous regulations by the federal government, principally the 
FDA, and foreign governments if products are tested or marketed abroad. In 
the United States, the FFDCA governs clinical trials and approval procedures 
as well as the development, manufacturing, safety, labeling, storage, record 
keeping and marketing of pharmaceutical products and medical devices. 
Biological products are subject to similar regulation under both the FFDCA 
and the Public Health Service Act. Because the Company offers services 
relating to the conduct of clinical trials and the preparation of the 
marketing applications, the Company is obligated to comply with applicable 
regulatory requirements governing these activities, both in the United States 
and in foreign countries. Requirements governing these activities vary from 
country to country. 

   In the United States, the Company is subject to inspection by the FDA to 
evaluate compliance with applicable requirements governing the conduct of 
clinical trials. If the FDA discovers that the Company has violated 
applicable requirements relating to the conduct of clinical trials or the 
preparation of marketing applications, discussed in more detail below, the 
FDA may take enforcement action such as issuance of a Warning Letter; 
termination of a clinical study; refusal to approve clinical trial or 
marketing applications or withdrawal of such applications; injunction; 
seizure of investigational products; civil penalties; or recommending 
criminal prosecutions. Pursuant to the FDA's fraud policy, the FDA generally 
will refuse to approve a pending clinical trial or marketing application, or 
withdraw such application, if it discovers conduct such as submission of 
fraudulent applications, making untrue statements of material facts, or 
giving or promising bribes or illegal gratuities. The Company also is subject 
to both mandatory and permissive debarment by FDA, which would prohibit the 
Company from assisting in the submission of abbreviated new drug applications 
for generic drugs. Conviction of criminal conduct relating to the development 
or approval of an abbreviated drug application is a prerequisite to such 
debarment. Such sanctions could have a material adverse effect on the 
Company. 

   The following is a summary of the specific requirements relating to the 
clinical testing and approval of drugs, biologics and devices follows. 


   Drug Development and Approval in the United States -- An Overview 

   Drug products marketed in the United States usually require approval by 
the FDA before marketing. The steps required before a new prescription drug 
may be marketed in the United States include (i) preclinical labo-

                                       32
<PAGE>


ratory and animal tests; (ii) the submission to the FDA of an Investigational 
New Drug application ("IND"), which must be evaluated and found acceptable by 
the FDA before human clinical trials may commence; (iii) adequate and 
well-controlled human clinical trials to establish the safety and 
effectiveness of the drug; (iv) the submission of a New Drug Application 
("NDA") to the FDA; and (v) FDA approval of the NDA. The Company's services 
relate to steps (ii) through (iv) of this process. 


   Clinical trials to evaluate the safety and effectiveness of drugs are 
generally conducted in three sequential phases that may overlap. In Phase I 
(typically lasting from 6 months to one year), the drug is introduced into a 
small number of human subjects, usually healthy volunteers, to determine 
safety (adverse effects), dosage tolerance, metabolism, distribution, 
excretion and clinical pharmacology. Phase II (typically lasting from one to 
two years) involves clinical trials in a limited patient population to 
determine the effectiveness of the pharmaceutical for specific targeted 
indications, to determine dosage tolerance and optimal dosage and to identify 
possible adverse side effects and safety risks. After a compound has been 
shown in Phase II trials to have an acceptable safety profile and probable 
effectiveness, Phase III trials (typically lasting from 2 to 3 years) are 
undertaken in an expanded patient population at multiple clinical sites to 
further evaluate clinical effectiveness and safety within an expanded patient 
population. 


   Prior to commencing each phase of a clinical trial, a drug sponsor must 
submit an IND application to the FDA. The IND application must contain, among 
other things, protocols for each study; a description of the composition, 
manufacture, and control of the drug substance and the drug product; 
information about preclinical pharmacological and toxicological studies of 
the drug; and a summary of previous human experience with the investigational 
drug. Unless the FDA objects, the IND will become effective 30 days following 
its receipt by the FDA. If the FDA has concerns about the proposed clinical 
trial, it may delay the trial and require modifications to the trial protocol 
prior to permitting the trial to begin. In addition, all clinical trials of 
new drugs must obtain approval of the IRB(s) at each institution at which the 
trial is conducted. The IRB reviews the study to verify the method of 
experimentation, safety, and ensure that subjects give their informed consent 
to participate in the clinical trial. 


   When results from a Phase II or Phase III study show promise in the 
treatment of a serious or immediately life-threatening disease in patients 
for whom no comparable or satisfactory alternative drug or other therapy 
exists, the FDA may allow the manufacturer to make the new drug available to 
a larger number of patients through the regulated mechanism of a treatment 
IND. Although less scientifically rigorous than a controlled clinical trial, 
the treatment IND facilitates availability of promising drugs to ill patients 
prior to general marketing and also allows sponsors to obtain additional data 
on the drug's safety and effectiveness. In general, treatment use of an 
investigational drug is conditioned upon compliance with safeguards of the 
IND process such as informed consent, IRB approval, and other requirements. 


   Once a clinical trial with proper IRB and IND approval is commenced, the 
conduct of the clinical trial is governed by extensive FDA regulations. 
Clinical trial sponsors (i.e., the persons who initiate the trials but do not 
actually conduct the investigations) are responsible for the selection of 
qualified investigators, providing investigators with protocols and other 
necessary information, monitoring the investigation, reporting changes in 
study protocol to the FDA, reporting to the FDA and investigators safety 
reports of serious and unexpected adverse experiences associated with use of 
the drug, and maintaining records concerning the study. To the extent that 
the Company performs these functions on behalf of a drug sponsor, the Company 
must comply with these requirements. 

   Upon completion of clinical trials that demonstrate the safety and 
efficacy of a new drug, a drug sponsor must submit an NDA and obtain FDA 
approval of an NDA prior to marketing the drug. The NDA must include 
information pertaining to the composition, manufacture, and specification of 
the drug substance; a description of the preclinical studies; a description 
of the human pharmacokinetic data and human bioavailability data; 
descriptions of clinical investigations; a statistical evaluation of the 
clinical data; and proposed labeling. Submission of an NDA does not assure 
the FDA approval for marketing. The application review process generally 
takes at least two to three years to complete, and the FDA may require 
additional data or other studies during the course of its review. 
Notwithstanding the submission of such data, the FDA ultimately may decide 
that the application does not satisfy its regulatory criteria for approval. 
Finally, the FDA may require additional clinical testing following NDA 
approval to confirm safety and efficacy (Phase IV clinical tests). No 
assurance exists that clinical studies conducted will provide sufficient 
information to support the filing of an NDA. 


                                       33
<PAGE>

   Clinical trials may be conducted outside of the United States without an 
IND. The FDA will accept data from such foreign clinical trials to support 
clinical investigations in the United States and/or approval of an NDA only 
if the agency determines that the trials are well-designed, well-conducted, 
performed by qualified investigators, and conducted in accordance with 
internationally recognized ethical principles. 

   Less extensive approval requirements can apply to generic drugs. 
Abbreviated requirements are applicable to drugs that are, for example, 
either bioequivalent to brand name "pioneer" drugs, or otherwise similar to 
pioneer drugs, such that all the safety and efficacy studies previously 
conducted on the pioneer product need not be repeated for approval. Changes 
in approved drug products, such as in the delivery system, dosage form or 
strength, can also be the subject of abbreviated application requirements. 

   Biological Product Development and Approval in the United States -- An 
Overview 


   Like drugs and medical devices, biological products (i.e., those derived 
from living materials of humans, plant, animals or microorganisms, such as 
vaccines) are subject to extensive regulation by FDA. Biological products are 
regulated primarily under the Public Health Service Act, but are also subject 
to regulation under the FFDCA. 

   While some biological products may be approved for marketing via a new 
drug application ("NDA"), most manufacturers must obtain two licenses from 
FDA prior to marketing a biological product: a license for the manufacturing 
establishment, and a product license. In order to obtain a product license, a 
manufacturer must obtain FDA approval of a product license application 
("PLA"). Similar to an NDA, a PLA must contain the following information: 
nonclinical and clinical data demonstrating the product's safety, purity and 
potency; a description of the manufacturing methods; data regarding the 
product's stability; test results for the lots represented by the submitted 
samples, and samples of the product and its labeling. 

   The sponsor of a clinical trial involving a biological product must file 
an IND with FDA, unless the product is exempt from such requirement. Once the 
IND becomes effective, the conduct of the clinical trial is governed by the 
same regulatory requirements governing drug clinical trials. Thus, to the 
extent that the Company performs these functions on behalf of the biological 
product sponsor, the Company must comply with these requirements. 


   Device Development and Approval in the United States -- An Overview 


   The FFDCA and regulations thereunder require that, unless exempted by 
regulation, all products meeting the statutory definition of "device" receive 
the FDA clearance of a premarket notification (510(k) submission or FDA 
approval of a premarket approval ("PMA") application prior to marketing in 
the United States. Generally, devices are distinguished from drugs through 
the characteristic of acting or achieving their effect through means other 
than pharmacologic action. 

   The FDA categorizes medical devices into three regulatory classifications 
(Class I, II, and III) on the basis of controls deemed reasonably necessary 
to ensure their safety and effectiveness. Class I devices are subject to 
general controls (e.g., labeling, premarket notification, and adherence to 
good manufacturing practice regulations for medical devices), and Class II 
devices are subject to general controls and special controls (e.g., 
performance standards, postmarket surveillance, patient registries and FDA 
guidelines). Class III devices (generally including life-sustaining, 
life-supporting, or implantable devices, or new devices that have been found 
not to be substantially equivalent to a legally marketed predicate device) 
are those which must receive premarket approval ("PMA") prior to marketing. 

   Before a new device can be introduced into the market, the manufacturer 
must generally obtain marketing clearance or approval through either a 510(k) 
premarket notification or a PMA. A 510(k) clearance will be granted if the 
submitted information establishes that the proposed device is "substantially 
equivalent" to a legally marketed "predicate" device (i.e., a Class I or II 
medical device, or to a Class III medical device for which the FDA has not 
called for a PMA). The 510(k) must include, among other information, proposed 
labeling and advertisements; data demonstrating substantial equivalence to a 
claimed predicate; and any additional information regarding the device 
requested by the FDA that is necessary to make a finding as to substantial 
equivalence to a predicate device. The FDA can require clinical studies to 
demonstrate that a device is as safe and effective as the predicate device. 
The FDA recently has been requiring a more rigorous demonstration of 
substantial 


                                       34
<PAGE>

equivalence than in the past. It generally takes from four to twelve months 
from submission of a 510(k) to obtain 510(k) clearance, but it may take 
longer. The FDA may determine that a proposed device is not substantially 
equivalent to a legally marketed device, or that additional information or 
data are needed before a substantial equivalence determination can be made. 

   If a manufacturer cannot establish that a proposed device is substantially 
equivalent to a legally marketed predicate device, the manufacturer must seek 
premarket approval of the proposed device from the FDA through the submission 
of a PMA application. A PMA application must be supported by extensive data, 
including nonclinical laboratory studies or animal testing; clinical trial 
data; and a bibliography of all published reports reasonably known to the 
manufacturer concerning safety or effectiveness. In addition, the PMA must 
include a full description of the device and its components; the principle of 
operation of the device; a full description of the methods, facilities and 
controls used for manufacturing, processing, packing, storage and, where 
appropriate, installation; and proposed labeling. Upon receipt of a PMA 
application, the FDA makes a threshold determination as to whether the 
application is sufficiently complete to permit a substantive review. If the 
FDA determines that the PMA application is sufficiently complete to permit a 
substantive review, the FDA will accept the application for filing. 


   Once the submission is accepted for filing, the FDA begins an in-depth 
review of the PMA. An FDA review of a PMA application generally takes one to 
two years from the date the PMA application is accepted for filing, but may 
take significantly longer. The review time is often significantly extended by 
the FDA asking for more information or clarification of information already 
provided in the submission. During the review period, an advisory committee, 
typically a panel of clinicians, will likely be convened to review and 
evaluate the application and provide recommendations to the FDA as to whether 
the device should be approved. The FDA is not bound by the recommendations of 
the advisory panel. If the FDA's evaluation of the PMA application is 
favorable, the FDA will issue either an approval letter or an approvable 
letter, which usually contains a number of conditions which must be met in 
order to secure final approval of the PMA. When and if those conditions have 
been fulfilled to the satisfaction of the FDA, the FDA will issue a PMA 
approval letter, authorizing marketing of the device for certain indications. 
If the FDA's evaluation of the PMA application is not favorable, the FDA will 
deny approval of the PMA application or issue a "not approvable" letter. The 
FDA may also determine that additional clinical trials are necessary, in 
which case PMA approval may be delayed for several years while additional 
clinical trials are conducted and submitted in an amendment to the PMA. 

   Human clinical trials are always required to support a PMA application, 
and may be required to support a 510(k) submission. If the device involved 
presents a "significant risk" to the patient, the clinical trial sponsor must 
obtain IRB approval for the study and must file an investigational device 
exemption ("IDE") application with the FDA prior to commencing human clinical 
trials. The IDE application must include reports of prior clinical and 
nonclinical investigations of the device; an investigational plan; a 
description of the methods, facilities, and controls used for the 
manufacture, processing, packing, storage, and, where appropriate, 
installation of the device; information concerning the investigators 
participating in the study and the IRB's that approved the study; copies of 
labeling; copies of forms to be provided to subjects to obtain informed 
consent; and other relevant information requested by the FDA. As with IND 
applications, the IDE will become effective 30 days following its receipt by 
the FDA unless the FDA objects to the application. If the FDA has concerns 
about the proposed clinical trial, it may delay the trial and require 
modifications to the trial protocol prior to permitting the trial to begin. 
Clinical trials involving a device that presents a "nonsignificant risk" to 
the patient may begin after the sponsor has obtained approval by one or more 
appropriate IRB's, but not the FDA. Such investigations are, nevertheless, 
subject to informed consent requirements, monitoring by the sponsor, and 
record keeping requirements. 

   As discussed with respect to clinical studies involving drugs, the FDA 
strictly regulates the conduct of all clinical trials involving medical 
devices, regardless of whether the clinical trial is conducted under an IDE. 
The sponsor of a clinical study involving a device is responsible for 
ensuring that proper IRB and/or FDA approval is obtained prior to commencing 
the study, selecting qualified investigators and informing investigators of 
all necessary information, monitoring the investigation, informing the IRB 
and the FDA about significant new information pertaining to the 
investigation, and maintaining accurate and current records concerning the 
investigation. The sponsor must evaluate unanticipated adverse effects and 
terminate the study if it presents an unreasonable risk to subjects. To the 
extent that the Company performs these functions on behalf of a 
investigational device sponsor, the Company must comply with these 
requirements. 


                                       35
<PAGE>


   The FDA will accept foreign clinical studies involving devices that are 
not conducted under an IDE if the data are valid and the investigator has 
conducted the studies in conformance with the "Declaration of Helsinki" or 
the laws and regulations of the country in which the research is conducted, 
whichever accords greater protection to human subjects. Foreign clinical data 
that meets these requirements may form the sole basis for PMA approval if the 
foreign data are applicable to the United States population and medical 
practice, studies were performed by clinical investigators of recognized 
competence, and (if necessary) the FDA validates the data through an on-site 
inspection or other means. 


   CLIA Requirements -- An Overview 

   The Company's clinical laboratory services are subject to the requirements 
of the Clinical Laboratory Improvement Amendments of 1988 ("CLIA"). This law 
requires all laboratories to meet specified standards in the areas including 
personnel qualification, administration, participation in proficiency 
testing, patient test management, quality control, and quality assurance. In 
addition, laboratories such as the Company's clinical laboratory must obtain 
appropriate certification under CLIA. The Company has obtained such 
certification for its clinical laboratory. 


   Under CLIA, the Company's clinical laboratory is subject to inspection by 
the United States Department of Health and Human Services or a designee. 
Violations of the CLIA requirements may result in sanctions including 
suspension, limitation, or revocation of certification; enjoinment of 
laboratory activities; civil money penalties; or criminal prosecution for 
intentional violations. There can be no assurance that the regulations under, 
and future administrative interpretations of, CLIA will not have an adverse 
impact on the Company's services in this area. 


   Foreign Regulatory Requirements 


   The Company also is subject to foreign regulatory requirements governing 
clinical trials and product approval requirements. Whether or not the FDA 
approval has been obtained to conduct a clinical trial or market an 
FDA-regulated product, approval by comparable regulatory authorities in 
foreign countries usually must be obtained to conduct such activities in 
those countries. See "Risk Factors -- Dependence on Government Regulation." 


POTENTIAL LIABILITY AND INSURANCE 


   The Company attempts to manage its risk of liability for personal injury 
or death to patients from administration of products under study through 
contractual indemnification provisions with clients and through insurance 
maintained by the Company and its clients. Contractual indemnification 
generally does not protect the Company against certain of its own actions, 
such as negligence. The terms and scope of such indemnification vary from 
client to client and from trial to trial. Although most of the Company's 
clients are large, well capitalized companies, the financial viability of 
these indemnification provisions cannot be assured. Therefore, the Company 
bears the risk that the indemnifying party may not have the financial ability 
to fulfill its indemnification obligations. The Company also maintains 
professional liability insurance in the amount of $1 million per claim and $3 
million in the aggregate. 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 beyond the scope of an indemnity provision or 
beyond the scope or level of insurance coverage maintained by it or the 
client or where the indemnifying party does not fulfill its indemnification 
obligations. See "Risk Factors -- Potential Liability." 


INTELLECTUAL PROPERTY 


   The Company's services have been enhanced by significant investment in 
information technology. The Company's information services group is committed 
to achieving operating efficiencies through technical advances. The Company 
has developed certain computer software and technically derived procedures 
that it seeks to protect through a combination of contract law, copyrights, 
trademarks, and trade secrets. Although the Company does not believe that its 
intellectual property rights are as important to its results of operations as 
are such factors as technical expertise, knowledge, ability and experience of 
the Company's professionals, the Company believes that its technical 
capabilities provide significant benefits to its clients.

EMPLOYEES 


   At September 30, 1996, the Company had 120 employees. At the U.S. location 
in Philadelphia, PA, the Company had 101 employees (79 full-time, 22 
part-time). At the U.K. location in Peterborough, the Company had 19 
employees (18 full-time, 1 part-time). On September 30, 1996, 20 employees 
held M.D., Ph.D. or other masters or post-graduate degrees. The Company 
believes that its relations with its employees are good. 


FACILITIES 


   The Company leases all of its facilities. The Company's principal offices 
are located in Philadelphia, PA, where it leases approximately 35,000 square 
feet under a lease expiring in 2003. This facility is owned by UM Holdings, 
Ltd. See "Certain Relationships." The Company also maintains an office of 
approximately 9,000 square feet in Peterborough, U.K. The Company believes 
that the leases generally reflect market rates in their respective geographic 
areas.

STOCK OPTION GRANTS 


   The following tables contain certain information concerning the grant of 
stock options under the Company's 1993 Non-Qualified Stock Option Plan during 
the year ended December 31, 1995, and the number and value of options held at 
December 31, 1995 by each of the Company's executive officers named in the 
Summary Compensation Table. These options will become exercisable on the 
sooner of July 1, 2003 or the 90th day following the closing of this 
offering. Prior to the offering, the Company has been privately-held and 
there has been no public market for its securities. The Company believes that 
the options were granted at prices in excess of the then fair market value of 
the stock.

(1) Assumes that the closing of this offering occurs on February 1, 1997. 


(2) Amounts represent hypothetical gains that could be achieved for the 
    options if exercised at the end of the option term. These gains are based 
    upon assumed rates of share price appreciation set by the Securities and 
    Exchange Commission of five percent and ten percent of the fair value of 
    the Common Stock on the date of grant of the options (which was 
    substantially less than the exercise price), compounded annually from the 
    date of grant to the option expiration date. The gains shown are net of 
    the option exercise price, but do not include deductions for taxes or 
    other expenses associated with the exercise. While these assumptions 
    result in no potential realizable value of the option, a calculation 
    based on the proposed initial public offering price would result in a 
    significant potential realizable value. Actual gains, if any, are 
    dependent on the performance of the Common Stock and the date on which 
    the option is exercised. 

(3) Excludes options for 11,005 shares and 22,010 shares granted to Mr. Evans 
    and Mr. Cousins, respectively, during 1995 and subsequently terminated.

STOCK OPTION PLANS 


   1993 Non-Qualified Stock Option Plan. The Company's 1993 Non-Qualified 
Stock Option Plan (the "1993 Plan") authorizes the grant of options to 
acquire up to 1,100,500 shares of the Company's Common Stock. The purpose of 
the 1993 Plan was to provide an incentive for key individuals to advance the 
success of the Company. The Plan is administered by a committee of not less 
than two directors, the members of which are ineligible to participate in the 
Plan. The Committee, in its discretion, determines who shall receive options 
under the Plan. 

   The 1993 Plan provides for the grant of non-qualified options to acquire 
the Company's Common Stock. The option price for each option which has been 
granted under the 1993 Plan is $2.27 per share. Each option granted under the 
1993 Plan will become exercisable on July 1, 2003 or on the 90th day 
following the closing of the initial public offering ("IPO") of the Company's 
Common Stock (the "IPO Date"), as defined, and will expire on the fifth 
anniversary of the IPO Date. The offering pursuant to this Prospectus will 
constitute an IPO, as defined in the 1993 Plan. In accordance with the terms 
of lock-up agreements entered into with the Company, the holders of the 
options have agreed not to sell shares of Common Stock owned by each of them 
without the prior written consent of Montgomery Securities for a period of 
180 days (365 days, in the case of Dr. Morganroth) following the first offer 
of shares of Common Stock pursuant to this Prospectus. See "Underwriting." 

   Options covering 517,235 shares of the Common Stock are outstanding under 
the 1993 Plan as of the date of this Prospectus. The Company does not 
anticipate granting any additional options under the Plan prior to the 
offering hereunder, and under the terms of the 1993 Plan, no further options 
can be granted under the 1993 Plan after the IPO Date. 


                                       41
<PAGE>

   1996 Stock Option Plan. The Company's 1996 Stock Option Plan (the "1996 
Plan") authorizes the grant of options to acquire up to 500,000 shares of the 
Company's Common Stock. Such options may be incentive stock options ("ISOs") 
within the meaning of the Internal Revenue Code of 1986, as amended, or 
options that do not qualify as ISOs ("Non-Qualified Options"). 


   The 1996 Plan is administered by a Committee of the Board of Directors 
(the "Committee") consisting of not less than two directors of the Company. 
The Committee has full power and authority to interpret the provisions, and 
supervise the administration, of the 1996 Plan. It determines, subject to the 
provisions of the 1996 Plan, to whom options are granted, the number of 
shares of Common Stock subject to each option, whether an option shall be an 
ISO or a Non-Qualified Option and the period during which each option may be 
exercised. In addition, the Committee determines the exercise price of each 
option, subject to the limitations provided in the 1996 Plan. The exercise 
price per share of any ISO granted under the Plan may not be less than 100% 
of the fair market value per share of Common Stock on the date of grant (110% 
of such fair market value if the grantee owns stock representing more than 
10% of the combined voting power of all classes of the Company's stock). The 
aggregate fair market value (determined as of the time such option is 
granted) of the Common Stock for which any employee may have ISOs which 
become exercisable for the first time in any calendar year may not exceed 
$100,000. 

   ISOs may have an exercise option period of up to 10 years (five years for 
optionees who own more than 10% of the total combined voting power of all 
classes of stock of the Company or its parent or any subsidiary corporation). 
Non-Qualified Options will have an exercise option period as specified by the 
Committee at the time of grant. 


   The 1996 Plan provides that upon termination of employment of the optionee 
for any reason other than death or disability, the right to exercise the 
option (to the extent otherwise exercisable) will terminate within three 
months following cessation of employment. In the event of termination of 
employment due to death or disability, the same provisions apply except that 
the period of time for exercise is one year. 

   The options granted pursuant to the 1996 Plan are not transferable except 
in the event of death. Options may be granted under the 1996 Plan to 
employees and directors of the Company and to others providing services or 
having a relationship with the Company. No options may be granted under the 
1996 Plan after November 18, 2006. 


   At the present time, no options have been granted under the 1996 Plan. The 
Company has agreed to grant to an employee an option for 10,000 shares 
pursuant to the 1996 Plan, at the offering price hereunder. The Company has 
no other current plans to grant options under the 1996 Plan. 


401(K) PLAN 


   The Company has participated in a deferred savings program for employees 
pursuant to Section 401(k) of the Internal Revenue Code of 1986 sponsored by 
UM, for which the Company is charged for the profit sharing plan 
contributions made with respect to its employees. During 1997, the Company 
intends to adopt its own 401(k) program, which will be substantially 
identical to the UM program. Under the 401(k) program, full-time employees of 
the Company who have completed at least one year of employment may elect to 
defer receipt of a specified portion of their compensation, with the Company 
providing limited matching contributions. Subject to certain limitations 
relating to non-discrimination, a participant is permitted to contribute 
between 2% and 10% of his or her compensation to the program. The Company 
makes matching contributions, up to 6% of compensation, equal to 25% to 100% 
of the employee's contribution, based upon years of service. The amount that 
may be contributed by a participant in any single year may not exceed an 
amount specified by law, which for 1996 was $9,500. Vesting of Company 
contributions commence upon the completion of two years of service and then 
increases until full vesting occurs upon completion of five years of service. 
An employee's contributions are fully vested immediately. 


COMPENSATION COMMITTEE INTERLOCKS AND INSIDER PARTICIPATION 


   The Compensation and Personnel Committee is composed of Mr. Lee and Ms. 
Woodburn, neither of whom is a current or former officer or employee of the 
Company. 


                                       42
<PAGE>


   Prior to the formation of the Compensation and Personnel Committee, 
decisions with respect to executive compensation were determined by the Board 
which, at the time of such determinations, was composed of John Aglialoro and 
Joan Carter. Ms. Carter is the Chairman of the Board, and Mr. Aglialoro is a 
director of the Company. They also are executive officers, directors and the 
principal stockholders of UM, which prior to this offering was the principal 
stockholder of the Company. See "Certain Relationships". 


                      PRINCIPAL AND SELLING STOCKHOLDERS 


   Of the shares of Common Stock offered hereby, 750,000 are being sold by UM 
Holdings, Ltd. through its wholly-owned subsidiary UM Equity Corp. 
(collectively, "UM"). The Company will not receive any of the proceeds from 
the shares of Common Stock being sold by UM. Substantially all of the capital 
stock of UM is owned equally by John Aglialoro and Joan Carter. 

   The following table sets forth certain information with respect to the 
beneficial ownership of the Common Stock of the Company by UM, the Company's 
directors and executive officers, and each other person known to the Company 
to own beneficially more than 5% of the Common Stock, and as adjusted to 
reflect UM's sale of Common Stock in this offering.

                            CERTAIN RELATIONSHIPS 

   The Company or its predecessors have been direct or indirect subsidiaries 
or divisions of UM since 1977. Upon closing of the offering, UM will 
indirectly own approximately 44.4% of the Company's Common Stock (40.1% if 
the Underwriters' over-allotment option is exercised in full). John Aglialoro 
and Joan Carter, who are married, are executive officers, directors and the 
principal stockholders of UM; Ms. Carter is the Chairman and Mr. Aglialoro is 
a director of the Company. 


   UM has had the following arrangements with the Company: 


   The Company's principal executive and operations facility is owned by UM 
and leased to the Company. The current annual rent under this lease is 
$349,200. The Company believes that the terms of this lease are as favorable 
to the Company as would have been obtained through arms-length negotiations 
with an unrelated party. See "Business -- Facilities." 

   UM has historically provided various administrative services to the 
Company, including accounting, human resources and computer services, for 
which it was charged $160,000 in 1995. In 1996, UM decentralized most of 
these functions, and now provides primarily 401(k) administrative services. 
For the nine months ended September 30, 1996, UM charged the Company $43,000. 
The Company also has participated in UM's deferred savings program for 
employees pursuant to Section 401(k) of the Internal Revenue Code. The 
Company was charged $59,000 and $65,000 for 1995 and the nine months ended 
September 30, 1996, respectively, for profit sharing plan contributions made 
pursuant to this program on behalf of its employees. During 1997, the Company 
expects to adopt its own Section 401(k) program, which will be substantively 
identical to the UM program. Until April 1996, the Company participated in 
UM's centralized cash management program. Pursuant to this program, the 
Company's cash receipts were remitted to, and cash disbursements were funded 
by, UM, with UM retaining any excess cash. 

   The Company performed blood and urine analysis services for a subsidiary 
of UM. The Company charged market fees for these services of $115,000 and 
$7,000 for 1995 and the nine months ended September 30, 1996, respectively. 
The Company utilized a different UM subsidiary for subcontracted diagnostic 
services, for which it incurred market fees of $94,000 and $122,000 for 1995 
and the nine months ended September 30, 1996, respectively. The Company does 
not anticipate using these subcontracted services in the future. The Company 
sold fixed assets to UM at their carrying values of $66,000 and $29,000 for 
1995 and the nine months ended September 30, 1996, respectively. 


   The Company is, and until the closing of the offering hereunder will 
continue to be, included in the consolidated income tax filings of UM. The 
Company, UM and other subsidiaries of UM have entered into a tax sharing 
agreement pursuant to which the Company will pay to UM amounts equal to the 
income taxes which the Company would otherwise have paid had it filed 
separate income tax returns. 


   Certain of the Company's diagnostic testing and clinical research 
contracts require that specified medical professional services be provided by 
Dr. Morganroth, the Company's President and Chief Executive Officer. The 
Company has retained Joel Morganroth, M.D., PC, a professional corporation 
owned by Dr. Morganroth, to provide these and other services, which include 
serving as Medical Director to the Company, acting as principal investigator 
for various studies, and providing medical interpretation for diagnostic 
tests from time to time as required. These arrangements resulted in payments 
to the professional corporation during 1995 and the nine month period ended 
September 30, 1996 of $956,000 and $1,621,000, respectively. Effective 
January 1, 1997, the professional corporation will receive a fixed annual fee 
of $144,000. 

   In January 1996, UM sold 660,300 shares of the Company's outstanding 
Common Stock to Dr. Morganroth and, in connection therewith, loaned Dr. 
Morganroth $750,000. This collateralized loan, which bears interest at 5.5% 
per annum, is payable on December 31, 1997. 

   During 1995, the Company and PREMIER, Inc. formed a limited liability 
company, owned 65% by the Company and 35% by PREMIER, Inc. Upon the closing 
of this offering, PREMIER, Inc.'s interest in the limited liability company 
will convert into 330,150 shares of the Company's Common Stock. Connie 
Woodburn, a director of the Company, serves as Executive Vice President of 
PREMIER, Inc.

                         DESCRIPTION OF CAPITAL STOCK 
GENERAL 


   The Company's authorized capital stock consists of 15,000,000 shares of 
Common Stock, $.01 par value, and 500,000 shares of Preferred Stock, $10 par 
value. 


COMMON STOCK 


   As of November 15, 1996, there were 4,732,150 shares of Common Stock 
outstanding. The holders of shares of Common Stock are entitled to one vote 
per share held on all matters submitted to a vote of stockholders of the 
Company and do not have cumulative voting rights. Accordingly, holders of a 
majority of the shares of the Common Stock entitled to vote in any election 
of directors may elect all of the directors standing for election, and after 
the offering the current stockholders and directors and officers of the 
Company will be able to elect all of the directors. In addition, holders of 
the Common Stock are entitled to receive ratably such dividends, if any, as 
may be declared from time to time by the board of directors out of funds 
legally available therefor. In the event of the dissolution, liquidation or 
winding up of the Company, the holders of Common Stock are entitled to share 
ratably in all assets remaining after payment of all liabilities of the 
Company. Dividend and liquidation rights attributable to the Common Stock 
would be subject to any preferential rights associated with any outstanding 
Preferred Stock. Holders of Common Stock have no preemptive, subscription, 
redemption or conversion rights. All outstanding shares of Common Stock are, 
and the shares of Common Stock offered by the Company in this offering will 
be, when issued, fully paid and nonassessable. 


PREFERRED STOCK 

   Presently, there are no shares of Preferred Stock outstanding. The Board 
of Directors has the authority to issue Preferred Stock in one or more 
series, and to fix the rights, preferences, privileges and restrictions, 
including dividend, conversion, voting, redemption (including sinking fund 
provisions), and other rights, liquidation preferences and the number of 
shares constituting any series and the designations of such series, without 
any further vote or action by the shareholders of the Company. The rights and 
preferences of the Preferred Stock may be senior to the rights and 
preferences of the Common Stock. Because the terms of the Preferred Stock may 
be fixed by the Board of Directors of the Company without stockholder action, 
the Preferred Stock could be issued quickly with terms calculated to defeat a 
proposed takeover of the Company, or to make the removal of the management of 
the Company more difficult. Under certain circumstances, this could have the 
effect of decreasing the market price of the Common Stock. 

DELAWARE LAW AND CERTAIN CHARTER AND BY-LAW PROVISIONS 

   The Company is subject to the provisions of Section 203 of the General 
Corporation Law of Delaware. In general, Section 203 prohibits a 
publicly-held Delaware 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 became an interested stockholder, 
unless the business combination is approved in a prescribed manner. A 
"business combination" includes mergers, asset sales and other transactions 
resulting in a financial benefit to the interested stockholder. Subject to 
certain exceptions, an "interested stockholder" is a person who, together 
with affiliates and associates, owns, or within three years did own, 15% or 
more of the corporation's voting stock. 

   The Certificate of Incorporation of the Company requires an affirmative 
super-majority (80%) stockholder vote before the Company can enter into 
certain defined business combinations, except for combinations that meet 
several specified conditions. These provisions, as well as the provisions of 
the Certificate of Incorporation described above relating to the staggered 
terms of the Board of Directors and the ability of the Board of Directors to 
issue shares of Preferred Stock, could discourage potential take-over 
attempts and may make more difficult attempts by stockholders to change the 
management of the Company. 

   The Company's Certificate of Incorporation contains certain provisions 
permitted under the General Corporation Law of Delaware relating to the 
liability of directors. The provisions eliminate a director's liability for 
monetary damages for a breach of fiduciary duty, except in certain 
circumstances involving wrongful acts, such 

                                       45
<PAGE>

as the breach of a director's duty of loyalty or acts or omissions which 
involve intentional misconduct or a knowing violation of law. The General 
Corporation Law of Delaware also authorizes the Company to indemnify its 
directors and officers. The Company believes that these provisions will 
assist the Company in attracting and retaining qualified individuals to serve 
as directors.

                       SHARES ELIGIBLE FOR FUTURE SALE 


   Upon completion of this offering, the Company will have 6,732,150 shares 
of Common Stock outstanding. Of the shares outstanding upon completion of 
this offering, the 2,750,000 shares sold in this offering will be freely 
tradeable without restriction or registration under the Act, except for 
shares purchased by "affiliates" of the Company as that term is defined in 
Rule 144 under the Act. 

   The remaining 3,982,150 shares of Common Stock outstanding, and the 
540,441 shares issuable upon exercise of outstanding stock options, will be 
"restricted securities" (the "Restricted Shares") within the meaning of Rule 
144 under the Act, and may not be sold in the absence of registration under 
the Act unless an exemption from registration is available, including an 
exemption contained in Rule 144 or Rule 701 under the Act. 

   In general, Rule 144, as currently in effect, provides that any person (or 
persons whose shares are aggregated) who has beneficially owned shares for at 
least two years, including persons who may be deemed "affiliates" of the 
Company (as defined under the Act), is entitled to sell, within any 
three-month period, a number of shares that does not exceed the greater of 
(i) the average weekly trading volume in the Common Stock during the four 
calendar weeks preceding the date on which notice of such sale is filed with 
the Securities and Exchange Commission (the "Commission"), or (ii) 1% of the 
shares of Common Stock then outstanding. In addition, sales under Rule 144 
are subject to certain other restrictions regarding the manner of sale, 
required notice and availability of current public information concerning the 
Company. A person who is not deemed an "affiliate" of the Company, has not 
been an affiliate for at least three months prior to the sale and who has 
beneficially owned shares for at least three years after the later of the 
date the shares were acquired from the Company or the date they were 
purchased from an affiliate of the Company, is entitled to sell such shares 
under Rule 144(k) immediately without regard to the volume limitations and 
current public information requirements described above. Affiliates, 
including members of the Board of Directors and executive officers, continue 
to be subject to such limitations. 


   Shares issuable on the exercise of outstanding options may be eligible for 
sale in the public market pursuant to Rule 701 under the Act. In general, 
Rule 701 permits resale of shares issued pursuant to certain compensatory 
benefit plans and contracts commencing ninety days after the issuer becomes 
subject to the reporting requirements of the Exchange Act, in reliance upon 
Rule 144, but without compliance with certain restrictions of Rule 144, 
including the holding period requirements. 


   The Company, the Selling Stockholder (which prior to this offering is the
principal stockholder of the Company), all optionees (who will have the right to
acquire a total of 540,441 shares of Common Stock pursuant to stock options
exercisable 90 or 180 days following the closing of the offering hereunder), and
each other stockholder, executive officer and director of the Company have
agreed with the Representatives of the Underwriters that, subject to certain
exceptions, they will not offer, sell, contract to sell, grant any option to
purchase, or otherwise dispose of any shares of Common Stock, or any securities
convertible or exercisable or exchangeable for shares of Common Stock,
beneficially owned by them for a period of 180 days (365 days, in the case of
Dr. Morganroth) following the first offer of shares of Common Stock pursuant to
this Prospectus without the prior written consent of the Underwriters'
Representatives.


   Prior to this offering, there has been no market for the Common Stock of 
the Company and no prediction can be made as to the effect, if any, that 
market sales of shares or the availability of shares for sale will have on 
the market price prevailing from time to time. Nevertheless, sales of 
substantial amounts of Common Stock of the Company in the public market could 
adversely effect prevailing market prices.

   The Representatives have advised the Company that the Underwriters propose 
initially to offer the Common Stock to the public on the terms set forth on 
the cover page of this Prospectus. The Underwriters may allow to selected 
dealers a concession of not more than $   per share; and the Underwriters may 
allow, and such dealers may reallow, a concession of not more than $   per 
share to certain other dealers. After the offering, the offering price and 
other selling terms may be changed by the Representatives. The Common Stock 
is offered subject to receipt and acceptance by the Underwriters, and to 
certain other conditions, including the right to reject orders in whole or in 
part. 

   The Company and the Selling Stockholder have granted an option to the 
Underwriters, exercisable during the 30-day period after the date of this 
Prospectus, to purchase up to a maximum of 412,500 additional shares of 
Common Stock to cover over-allotments, if any, at the same price per share as 
the initial shares to be purchased by the Underwriters. To the extent that 
the Underwriters exercise this option, the Underwriters will be committed, 
subject to certain conditions, to purchase such additional shares in 
approximately the same proportion as set forth in the above table. The 
Underwriters may purchase such shares only to cover over-allotments made in 
connection with the offering. 


   The Underwriting Agreement provides that the Company and the Selling 
Stockholder will indemnify the Underwriters against certain liabilities, 
including civil liabilities under the Securities Act, or will contribute to 
payments the Underwriters may be required to make in respect thereof. 

   The Company and its directors, executive officers, and stockholders have
agreed that for a period of 180 days (365 days, in the case of Dr. Morganroth)
following the first offer of shares of Common Stock pursuant this Prospectus,
they will not, directly or indirectly, offer, sell, contract to sell, grant any
option to sell or otherwise dispose of, directly or indirectly, any shares of
Common Stock or securities convertible into or exchangeable for, or any rights
to purchase or acquire, Common Stock without the prior written consent of
Montgomery Securities. Montgomery Securities may, in its sole discretion and at
any time without prior notice, release all or any portion of the shares of
Common Stock subject to the lock-up agreements.


   The Representatives have informed the Company that the Underwriters do not 
expect to make sales of Common Stock offered by this Prospectus to accounts 
over which they exercise discretionary authority in excess of 5% of the 
offering. 

   Prior to the offering, there has been no public market for the Common 
Stock of the Company. Consequently, the initial public offering price will be 
determined by negotiations between the Company and the Representatives. Among 
the factors to be considered in such negotiations are the history of, and the 
prospects for, the Company and the industry in which it competes, an 
assessment of the Company's management, the Company's past and present 
operations, its past and present earnings and the trend of such earnings, the 
prospects for future earnings of the Company, the present state of the 
Company's development, the general condition of the securities markets at the 
time of the offering and the market price of and demand for publicly-traded 
common stocks of comparable companies in recent periods.

                   REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS 

To Premier Research Worldwide, Ltd.: 


We have audited the accompanying consolidated balance sheets of Premier 
Research Worldwide, Ltd. (an indirect subsidiary of UM Holdings, Ltd., see 
Note 1) and subsidiaries as of December 31, 1994 and 1995 and September 30, 
1996, and the related consolidated statements of operations, stockholders' 
equity and cash flows for each of the years in the three year period ended 
December 31, 1995, and for the nine months ended September 30, 1996. These 
financial statements are the responsibility of the Company's management. Our 
responsibility is to express an opinion on these financial statements based 
on our audits. 


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

In our opinion, the financial statements referred to above present fairly, in 
all material respects, the financial position of Premier Research Worldwide, 
Ltd. and subsidiaries, as of December 31, 1994 and 1995 and September 30, 
1996, and the results of their operations and their cash flows for each of 
the years in the three year period ended December 31, 1995, and for the nine 
months ended September 30, 1996, in conformity with generally accepted 
accounting principles.

              PREMIER RESEARCH WORLDWIDE, LTD. AND SUBSIDIARIES 

                  NOTES TO CONSOLIDATED FINANCIAL STATEMENTS 
(INFORMATION FOR THE NINE MONTH PERIOD ENDED SEPTEMBER 30, 1995 IS UNAUDITED) 

1. BACKGROUND AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES: 


   Premier Research Worldwide, Ltd. (the "Company"), a Delaware corporation, 
is a clinical research organization providing services to the worldwide 
pharmaceutical, biotechnology and medical device industries. The Company's 
services include centralized diagnostic testing, clinical trials management, 
clinical data management, biostatistical analysis, Phase I clinical research, 
health care economics and outcomes research and regulatory affairs services. 
The Company has an operating subsidiary in the United Kingdom (U.K.), is a 
65% majority owner of a limited liability company in the United States, 
Premier Research LLC (see Note 5) and is an indirect subsidiary of UM 
Holdings, Ltd. ("UM"). 

   For periods prior to June 1, 1994, the Company's business operated as 
direct or indirect subsidiaries or as divisions of UM. Effective June 1, 
1994, the net assets and operations of the division were transferred to the 
Company by UM. The transfer was recorded as a capital contribution of the 
carrying value of the division's net assets. 


PRINCIPLES OF CONSOLIDATION 


   The accompanying consolidated financial statements include the accounts of 
the Company, its subsidiaries and Premier Research LLC. All significant 
intercompany accounts and transactions have been eliminated. 


INTERIM FINANCIAL DATA 


   Interim financial information for the nine months ended September 30, 
1995, is unaudited. In the opinion of the Company, this financial information 
includes all adjustments, consisting of normal recurring adjustments, 
necessary to fairly present the financial information set forth. 


USE OF ESTIMATES 

   The preparation of financial statements in accordance with generally 
accepted accounting principles requires management to make estimates and 
assumptions that affect the reported assets and liabilities and contingency 
disclosures at the date of the financial statements and the reported 
operations during the reporting period. Actual results could differ from 
those estimates. 

REVENUES 


   Revenues are recorded when services are rendered. Revenues under certain 
clinical research service contracts are recognized under the 
percentage-of-completion method and include a proportion of the revenues 
expected to be realized on the contract in the ratio of costs incurred to 
estimated total costs. Such contracts are generally completed within 12 to 18 
months. The Company often receives non-refundable deposits from its customers 
that are recorded as deferred revenues in the accompanying balance sheets. 
For the year ended December 31, 1995 and for the nine months ended September 
30, 1995, the Company recognized revenues of $1,313,000 and $938,000, 
respectively, for such deposits related to customer project cancellations. 
The Company also recognizes rental revenue on equipment in connection with 
its diagnostic services. 


CASH AND CASH EQUIVALENTS 


   Until 1996, UM maintained a centralized cash management function for its 
subsidiaries, including the Company. Settlement of all cash disbursement and 
collection transactions by UM on behalf of the Company are recorded through 
equity. In 1996, UM decentralized its cash management function for its 
subsidiaries and, therefore, the Company now maintains its own bank accounts. 
The Company has always maintained a bank account in the U.K. 


                                       F-7
<PAGE>

   Cash and cash equivalents include highly liquid investments purchased with 
an original maturity of three months or less. 

PROPERTY AND EQUIPMENT 

   Property and equipment are stated at cost. Depreciation is provided using 
the straight-line method over the estimated useful lives of the assets 
ranging from three to five years. Leasehold improvements are amortized over 
the lease term. Repair and maintenance costs are expensed as incurred. 
Improvements and betterments are capitalized. Gains or losses on the 
disposition of property and equipment are charged to operations. Depreciation 
expense was $777,000, $1,149,000, $965,000, $750,000 and $520,000 for the 
years ended December 31, 1993, 1994 and 1995 and for the nine months ended 
September 30, 1995 and 1996, respectively. 

GOODWILL 

   Goodwill is amortized using the straight-line method over five years and 
is net of accumulated amortization of $125,000, $173,000, and $209,000 as of 
December 31, 1994 and 1995 and September 30, 1996, respectively. The related 
amortization expense was $8,000, $48,000, $48,000, $36,000 and $36,000 for 
the years ended December 31, 1993, 1994 and 1995 and for the nine months 
ended September 30, 1995 and 1996, respectively. 

   The Company continually evaluates whether later events and circumstances 
have occurred that indicate the remaining estimated useful life may warrant 
revision or that the remaining goodwill balance may not be recoverable. If 
factors indicate that goodwill should be evaluated for possible impairment, 
the Company would use an estimate of the related undiscounted operating 
income over the remaining life in measuring whether goodwill is recoverable. 

ACCRUED EXPENSES 

   Included in accrued expenses at December 31, 1994 and 1995 and at 
September 30, 1996 is accrued payroll of $267,000, $98,000 and $217,000, 
respectively. 

ADVERTISING COSTS 

   The Company expenses advertising costs as incurred. Advertising expense 
for the years ended December 31, 1993, 1994 and 1995 and for the nine months 
ended September 30, 1995 and 1996 was $657,000, $65,000, $118,000, $45,000 
and $81,000, respectively. 

INCOME TAXES 

   Income taxes are calculated using the liability method in accordance with 
Statement of Financial Accounting Standards No. 109, "Accounting for Income 
Taxes." Accordingly, deferred tax assets and liabilities are recognized 
currently for the future tax consequences attributable to differences between 
the financial statement carrying amounts of assets and liabilities and their 
respective tax bases. The Company is included in the consolidated federal tax 
return of UM and files separate state, local and foreign income tax returns. 
The accompanying financial statements reflect income tax expense calculated 
on a separate-company basis. 

SUPPLEMENTAL CASH FLOW INFORMATION 


   The Company paid approximately $71,000, $95,000, and $65,000 for income 
taxes in the years ended December 31, 1994 and 1995 and in the nine months 
ended September 30, 1996, respectively (see Note 6). 

   The minority owner of Premier Research LLC (see Note 5) contributed 
$50,000 of fixed assets in 1995. 


                                       F-8

CONCENTRATION OF CREDIT RISK AND SIGNIFICANT CUSTOMERS 


   Financial instruments that potentially subject the Company to 
concentration of credit risk consist primarily of trade accounts receivable 
from companies operating in the pharmaceutical industry. For the years ended 
December 31, 1993, 1994 and 1995 and for the nine months ended September 30, 
1996, two, two, three, and three clients accounted for 29%, 29%, 37% and 36% 
of the Company's net revenues, respectively. No other single client accounted 
for greater than 10% of net revenues during these periods. Receivables from 
these clients were $544,000, $889,000 and $1,724,000 at December 31, 1994 and 
1995 and at September 30, 1996. Due to the contract nature of the Company's 
business and the relative size of such contracts in comparison to the 
Company, it is not unusual for a significant customer in one year to be 
insignificant in the next year. The loss of any such client could have a 
material adverse effect on the Company's operations. In addition, the Company 
maintains reserves for potential credit losses and such losses, in the 
aggregate, have not historically exceeded management expectations. 


TRANSLATION OF FOREIGN FINANCIAL STATEMENTS 

   Assets and liabilities of the Company's U.K. subsidiary are translated at 
the exchange rate as of the end of each reporting period. The income 
statement is translated at the average exchange rate for the period. 
Cumulative adjustments from translating the U.K. financial statements are 
immaterial and, therefore, have been charged to income as incurred. 

PRO FORMA NET INCOME PER SHARE 


   The Company's historical stockholders' equity and net income does not 
reflect the conversion of the minority interest in Premier Research LLC (see 
Note 5), into Common Stock of the Company upon the closing of the Company's 
proposed initial public offering (see Note 11). Accordingly, historical net 
income per share is not considered meaningful and has not been presented. 

   Pro forma net income includes the minority interest in the limited 
liability company's income or loss. The shares used in computing pro forma 
net income per share include the effect of the minority interest conversion 
as if the conversion occurred on January 1, 1995. In addition, pursuant to 
SEC Staff Accounting Bulletin No. 83, all options granted during the twelve 
months preceding the initial filing of the Company's anticipated public 
offering have been included in the shares used in computing pro forma net 
income per share, using the treasury stock method (at an assumed initial 
public offering price of $15.00 per share), for all periods presented. The 
shares used in computing pro forma net income per share also include the 
dilutive effect of common stock equivalents outstanding during the periods, 
consisting of common stock options, using the treasury stock method. 


NEW ACCOUNTING PRONOUNCEMENTS 


   In March 1995, the Financial Accounting Standards Board issued Statement 
of Financial Accounting Standards No. 121 "Accounting for the Impairment of 
Long-Lived Assets and for Long-Lived Assets to be Disposed Of" (SFAS No. 
121). SFAS No. 121 established accounting standards for the impairment of 
long-lived assets, certain identifiable intangibles and goodwill. The Company 
adopted SFAS No. 121 effective January 1, 1996. The adoption did not have an 
effect on the Company's financial condition or results of operations. 

   In October 1995, the Financial Accounting Standards Board issued Statement 
of Financial Accounting Standards No. 123 "Accounting for Stock-Based 
Compensation" (SFAS No. 123). SFAS No. 123 established financial accounting 
and reporting standards for stock-based employee compensation plans. This 
statement also applies to transactions in which an entity issues its equity 
instruments to acquire goods or services from non-employees. The Company is 
required to adopt SFAS No. 123 for its December 31, 1996 financial 
statements. The Company has elected to adopt the disclosure requirement of 
this statement.

4. LINE OF CREDIT: 


   The Company has a line of credit with a bank, through June 1997, that 
provides for borrowings up to $1 million at an interest rate of prime plus 
 .5%. Borrowings are limited to 60% of eligible accounts receivable, as 
defined, and are secured by substantially all of the Company's assets. The 
line of credit agreement includes certain covenants, the most restrictive of 
which limit future indebtedness, dividends and equity issuances. To date, the 
Company has not borrowed any amounts under its line of credit. 

5. PREMIER RESEARCH LLC: 

   In September 1995, the Company and PREMIER, Inc. entered into the 
Agreement and Plan of Organization of a limited liability company, Premier 
Research LLC (Premier LLC). Under the terms of the agreement, PREMIER, Inc. 
contributed $300,000 in cash, $50,000 in property, $30,000 in services and 
the business operations of its Contract Research Organization Division for a 
35% interest in Premier LLC. The Company contributed $100 in cash, agreed to 
manage Premier LLC and agreed to fund Premier LLC's working capital needs for 
three years in exchange for a 65% interest in Premier LLC. Under the terms of 
the agreement, if the Company completes a public stock offering, as defined 
(see Note 11), PREMIER, Inc.'s ownership interest in Premier LLC will 
automatically convert into the number of shares of Common Stock equal to 7.5% 
of the outstanding Common Stock of the Company prior to the offering. 


6. INCOME TAXES: 


   The Company is included in the consolidated federal income tax return of 
UM. UM and the Company have entered into a tax-sharing agreement pursuant to 
which the Company will pay to UM amounts equal to the taxes that the Company 
would have paid had it filed a separate federal income tax return. The 
agreement does not provide for UM to pay the Company for tax losses. 
Therefore, any benefit related to tax losses has been recorded as a deemed 
distribution to UM in the accompanying financial statements. In addition, 
taxes payable to UM under the tax-sharing agreement for years prior to 1996 
have been forgiven by UM and, accordingly, have been recorded as 
contributions from UM.

7. RELATED PARTY TRANSACTIONS: 
TRANSACTIONS WITH UM 

   UM provided various administrative services to the Company including 
accounting, human resources and certain computer services prior to 1996. UM 
has historically charged the Company for these services through corporate 
allocations based primarily on actual costs incurred. These expenses were 
$150,000, $165,000, $160,000 and $120,000, for the years ended December 31, 
1993, 1994 and 1995, and the nine months ended September 30, 1995, 
respectively. In 1996, UM decentralized most of these functions, and now 
provides primar- ily 401(k) administrative services. For the nine months 
ended September 30, 1996, UM's charges were $43,000. 


                                      F-11
<PAGE>


   The Company is included in UM's consolidated income tax filings (see Note 
6), leases its primary operating facility from UM (see Note 9) and 
participates in UM's 401(k) profit sharing plan. The Company was charged 
$506,000, $709,000 $488,000, $366,000, and $294,000 for rent under the 
facility lease and $48,000, $53,000, $59,000, $46,000, and $65,000 for profit 
sharing plan contributions for the years ended December 31, 1993, 1994 and 
1995 and the nine months ended September 30, 1995 and 1996, respectively. The 
Company believes that all amounts charged by UM were reasonable. 

   Included in net revenues for the year ended December 31, 1995 and for the 
nine months ended September 30, 1995 and 1996 is $115,000, $60,000 and 
$7,000, respectively, charged to a UM subsidiary, for laboratory testing 
services. Included in direct costs for the years ended December 31, 1993, 
1994 and 1995 and for the nine months ended September 30, 1995 and 1996 is 
$59,000, $312,000, $94,000, $68,000 and $122,000, respectively, charged by a 
UM subsidiary for certain subcontracted diagnostic testing services. In the 
years ended December 31, 1994 and 1995 and during the nine months ended 
September 30, 1996, the Company sold fixed assets to UM and certain of its 
subsidiaries at their carrying values of $8,000, $66,000 and $29,000, 
respectively.
 
Transactions with the Company's President 

   The Company's President, who is a stockholder, is a cardiologist who 
provides medical services to the Company as an independent contractor in 
addition to his role as President of the Company (see Note 9). Fees incurred 
under this consulting arrangement approximated $185,000, $680,000, $956,000, 
$731,000, and $1,621,000 for the year ended December 31, 1993, 1994 and 1995, 
and for the nine months ended September 30, 1995 and 1996, respectively, of 
which $144,000 per year represents fees for his role as the Company's Medical 
Director, as defined. Accordingly, the Medical Director fees are included in 
selling, general and administrative expenses and the incremental fees, which 
primarily relate to medical interpretations for diagnostic tests, are 
included in direct costs in the accompanying statements of operations. 

   The Company and the Company's President have entered into new employment 
and consulting agreements effective January 1, 1997 (see Note 9). 

   In January 1996, the President and UM entered into an agreement whereby 
the President purchased 660,300 shares of the Company's Common Stock from UM 
for $750,000. The President also has an outstanding option to purchase 
220,100 shares of Common Stock (see Note 8). 

8. STOCK OPTION PLANS: 

   In August 1993, the Company established a nonqualified stock option plan 
covering certain key employees. The options cover the purchase of Common 
Stock of the Company at exercise prices initially set above current fair 
value as determined by the Board of Directors. Options granted under the plan 
are exercisable on July 1, 2003 or earlier if there is a sale of the Company 
or a public offering of the Company's Common Stock, as defined. 

   Information with respect to outstanding options under the plan is as 
follows:

   As of September 30, 1996, no options were exercisable and there were 
583,265 additional options available for future grants under the plan. The 
Company does not anticipate granting any additional options under the plan 
prior to the Company's initial public offering (see Note 11) and under terms 
of the plan, no further options can be granted under the plan after the 
closing of the initial public offering. 

   In 1996, the Company adopted a new stock option plan (the "1996 Plan") 
that authorizes the grant of both incentive and non-qualified options to 
acquire up to 500,000 shares of the Company's Common Stock. The Company's 
Board of Directors determines the exercise price of the options under the 
1996 Plan. The exercise price of incentive stock options may not be below 
fair value on the grant date. Incentive stock options under the 1996 Plan 
expire 10 years from the grant date and are exercisable in accordance with 
vesting provisions set by the Board. No options are outstanding under the 
1996 Plan, however, the Company has agreed to grant an employee an option for 
10,000 shares at an assumed initial public offering price of $15.00 per share 
(see Note 11). 

   In January 1996 the Company granted a director an option for 4,402 shares 
of Common Stock at an exercise price of $1.14 per share. In addition, in 1996 
the Company granted two other directors options for 8,804 shares of Common 
Stock at the initial public offering price (see Note 11).

LEASES 

   The Company leases office space and equipment under operating leases, 
including its primary operating facility, which it leases from UM under a 
lease agreement executed in June 1996 that runs through September 2003 (see 
Note 7). In 1995, the Company entered into an agreement to sublet office 
space that was previously vacated. Accordingly, the Company reduced its 
reserve for the vacated lease payments by approximately $175,000 by recording 
a reduction to rent expense in 1995. The reserve for the vacated lease 
payments was approximately $246,000, $90,000 and $43,000 at December 31, 1994 
and 1995 and September 30, 1996, respectively, and is included in accrued 
expenses in the accompanying balance sheets. Future minimum lease payments as 
of September 30, 1996, without consideration of sublease income, are as 
follows:

AGREEMENTS WITH THE COMPANY'S PRESIDENT 


   The Company has entered into new employment and consulting agreements with 
its President (see Note 7). The employment agreement was executed in November 
1996, and becomes effective January 1, 1997, and continues through December 
31, 2001. Either the Company or the President may terminate the agreement at 
any time, with or without cause. However, if the Company terminates the 
agreement without cause, the Company must continue to pay the President's 
salary for a one year period subsequent to the termination. 

   The consulting agreement was executed in October 1996, and relates to the 
President's capacity as a medical doctor and cardiologist and, among other 
things, requires the President to serve as Medical Director and/or principal 
investigator for the Company in addition to providing medical interpretations 
of diagnostic tests from time to time, as required. Compensation under the 
consulting agreement is $144,000 per year. The consulting agreement commences 
on January 1, 1997 for a one year period and will continue thereafter from 
year to year unless terminated, as defined. The new consulting agreement 
replaced a prior agreement whereby the President received additional 
compensation for medical interpretations of diagnostic tests (see Note 7).

CONTINGENCIES 


   The Company believes it has adequate insurance coverage against possible 
liabilities that may be incurred in connection with the conduct of its 
business primarily as it relates to the testing of new drugs or medical 
devices. While the Company believes it operates safely and prudently, in 
addition to managing liability risks through contractual indemnification, 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 beyond the 
scope of an indemnity provision or insurance coverage, or if an indemnity is 
not upheld or if the claim exceeds the insurance policy limits.

11. RECAPITALIZATION: 


   The Company is contemplating an initial public offering of 2,750,000 
shares of its Common Stock, of which 750,000 will be sold by UM (see Note 7). 
In connection therewith, on October 24, 1996, the Company's Board of 
Directors approved an increase in the number of authorized shares of Common 
Stock to 15,000,000 shares and authorized 500,000 shares of Preferred Stock. 
In addition, on November 26, 1996, the Company effected a 2,201-for-one split 
of its Common Stock. The increase in authorized shares and the stock split 
have been retroactively reflected in the accompanying consolidated financial 
statements.

Item 13.  Other Expenses of Issuance and Distribution.

         The following is an estimate of the expenses to be incurred in
connection with the issuance and distribution of the securities being
registered, other than the underwriting discounts, commissions, and other

         SEC registration fee...............................    $  15,331.80
                                                                   ---------

         Transfer agent's fees and expenses.................    $       *
                                                                   ---------
         Attorneys' fees and expenses.......................    $       *
                                                                   ---------
         Blue sky fees......................................    $       *
                                                                   ---------
         Accountants' fees and expenses.....................    $       *
                                                                   ---------
         Miscellaneous......................................    $       *
                                                                   ---------

                                      TOTAL.................    $       *
                                                                   ---------

- --------------
         *To be supplied by Amendment.

         The above expenses will be paid by the Company, except that
registration and filing fees will be paid by the Company and the Selling
Stockholder pro rata according to the number of shares of Common Stock sold by
each.

Item 14.  Indemnification of Directors and Officers.

         Under Section 145 of the Delaware General Corporation Law, the Company
must indemnify each of its directors and officers against his expenses (that is,
reasonable costs, disbursements and counsel fees) in connection with any
proceeding involving such person by reason of his having been an officer,
director, employee or agent of the Company, or who is or was serving at the
request of the Company as a director, officer, employee or agent of another
corporation, partnership, joint venture, trust or other enterprise, to the
extent he is successful on the merits. Moreover, under such statutory provision
the Company has the corporate power to indemnify its officers and directors
against expenses and (in the case of proceedings other than those by or in the
right of the Company) liabilities incurred in such a proceeding, provided (i)
the officer or director has acted in good faith and in a manner reasonably
believed to be in, or not opposed to, the best interests of the Company and (ii)
with respect to any criminal proceeding, he had no reasonable cause to believe
his conduct was unlawful. In the case of a proceeding by or in the right of the
Company, however, such indemnification is not permitted if the individual is
adjudged to be liable to the Company, unless a court determines that he is
fairly and reasonably entitled to indemnity for such expenses as the court deems
proper.


                                      II-1

<PAGE>



         The determination of whether indemnification is proper under the
circumstances, unless made by a court, is determined by a majority of the
disinterested members of the Board of Directors or committee thereof, by
independent legal counsel if a quorum of the disinterested members of the Board
of Directors or committee thereof is not available or if the disinterested
members of the Board of Directors or a committee thereof so direct, or by the
stockholders.

         The Company's Bylaws require the Company to indemnify each director and
officer if Section 145 of the Delaware General Corporation Law permits the
Company to do so.

         The Company intends to obtain a directors' and officers' liability
insurance policy, which will afford officers and directors insurance coverage
for losses arising from claims based on breaches of duty, negligence, error and
other wrongful acts.

Item 15.  Recent Sales of Unregistered Securities.

         In November, 1996, the Company issued 4,400,000 shares of its Common
Stock to its stockholders, as a stock split effectuated by means of a stock
dividend. The issuance of such shares was exempt from the registration
requirements of the Act because there was no "sale" of such securities.

Item 17. Undertakings.

         The Company hereby undertakes to provide to the Underwriters at the
closing specified in the Underwriting Agreement certificates in such
denominations and registered in such names as required by the Underwriters to
permit prompt delivery to each purchaser.

         Insofar as indemnification for liabilities arising under the Securities
Act of 1933 (the "Act") may be permitted to directors, officers and controlling
persons of the Company pursuant to the foregoing provisions, or otherwise, the
Company has been advised 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. In the event that a claim for
indemnification against such liabilities (other than the payment by the Company
of expenses incurred or paid by a director, officer or controlling person of the
Company 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 Company 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 and will be governed by
the final adjudication of such issue.

         The Company hereby undertakes that, for determining any liability under
the Securities Act, it will treat the information omitted from the form of
Prospectus filed as a part of this Registration Statement in reliance upon Rule
430(A) and contained in a form of Prospectus filed by the Company under Rule
424(b)(1), or (4) or 497(h) under the Securities Act as part of this
Registration Statement as of the time the Commission declared it effective.


                                      II-3

<PAGE>





         The Company hereby undertakes that, for determining any liability under
the Securities Act, it will treat each post-effective Amendment that contains a
form of Prospectus as a new Registration Statement for the securities offered in
the Registration Statement, and the offering of the securities at that time as
the initial bona fide offering of those securities.

                    REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS

To Premier Research Worldwide, Ltd.:

We have audited in accordance with generally accepted auditing standards, the
consolidated financial statements of Premier Research Worldwide, Ltd. included
in this registration statement and have issued our report thereon dated November
20, 1996, except for the stock split discussed in Note 11, as to which the date
is November 26, 1996. Our audit was made for the purpose of forming an opinion
on the basic financial statements taken as a whole. The schedule of valuation
and qualifying accounts is the responsibility of the Company's management and is
presented for purposes of complying with the Securities and Exchange
Commission's rules and is not part of the basic financial statements. This
schedule has been subjected to the auditing procedures applied in the audit of
the basic financial statements and, in our opinion, fairly states in all
material respects the financial data required to be set forth therein in
relation to the basic financial statements taken as a whole.

           Class                 No. of Shares                 Per Share
           -----                 -------------                 ---------
           Common                 15,000,000                     $  0.01

           Preferred                 500,000                     $ 10.00


The relative rights, preferences and limitations of the shares of each class are
as follows:

         Preferred. The Board of Directors is authorized to adopt by resolution
at any time, or from time to time, amendments to the Certificate of
Incorporation in respect of any unissued and/or treasury shares of preferred
stock, and thereby to fix or change the division of shares of the preferred
stock into classes and/or into series within any class or classes, and the
determination of the relative rights, preferences and limitations of the shares
of any class or series. The authority of the Board with respect to each class or
series of preferred stock shall include, but not be limited to, determination of
the following:

         (a) The number of shares constituting that class or series and the
distinctive designation of that class or series;

         (b) The dividend rate on the shares of that class or series, whether
dividends shall be cumulative, and, if so, from which date or dates;

         (c) Whether that class or series shall have voting rights, in addition
to any voting rights provided by law, and, if so, the terms of such voting
rights;

         (d) Whether that class or series shall have conversion privileges and,
if so, the terms and conditions of such conversion, including provision for

determine;

redeemable, and, if so, the terms and conditions of such redemption, including
the date or dates upon or after which they shall be redeemable, and the amount
per share payable in case of redemption, which amount may vary under different
conditions;

         (f) The rights of the shares of that class or series in the event of
voluntary or involuntary liquidation, dissolution or winding up of the
Corporation; and

         (g) Any other relative rights, preferences and limitations of that
class or series as may be permitted or required by law.


                                       -2-

         Common. Each share of common stock shall be entitled to one vote on all
matters submitted to a vote of stockholders. The common stockholders shall be
entitled to such dividends as may be declared by the Board of Directors from
time to time, provided that required dividends, if any, on the preferred stock
have been paid or provided for. In the event of the liquidation, dissolution, or
winding up, whether voluntary or involuntary, of the Corporation, the assets and
funds of the Corporation available for distribution to stockholders, and
remaining after the payment to holders of preferred stock of the amounts to
which they are entitled, shall be divided and paid to the holders of the common
stock according to their respective shares.

                                    ARTICLE V

         (a) The number of directors which shall constitute the whole Board of
Directors shall be not less than two nor more than fifteen. The exact number of
directors within such maximum and minimum shall be determined by resolution duly
adopted by the Board of Directors by a majority vote of the whole Board.

         (b) The Board of Directors shall be divided into three classes, as
nearly equal in number as the then total number of directors constituting the
whole Board permits. At the meeting of stockholders, or by written consent in
lieu of such meeting, at or by which this Restated Certificate of Incorporation
is adopted, directors of the first class shall be elected to hold office for a
term expiring at the next ensuing annual meeting, directors of the second class
shall be elected to hold office for a term expiring at the second ensuing annual
meeting, and directors of the third class shall be elected to hold office for a
term expiring at the third ensuing annual meeting. At each annual meeting of
stockholders following such initial classification and election, directors in
numbers equal to the number of the class whose terms expire at the time of such
meeting shall be elected to hold office until the second succeeding annual
meeting of stockholders. Each director shall hold office until his successor is
elected and qualified, or until his earlier resignation or removal.

         (c) Newly created directorships resulting from any increase in the
authorized number of directors and any vacancies in the Board of Directors
resulting from death, resignation, retirement, disqualification, removal from
office or other cause may be filled only by a majority vote of the whole Board,
and directors so chosen shall hold office for a term expiring at the annual
meeting of stockholders at which the term of the class to which they have been
elected expires.

         (d) Any directors elected pursuant to any special voting rights of one
or more series of preferred stock shall be excluded from, and for no purpose be
counted in, the scope and operation of the foregoing provisions of this Article
V.

         (e) Notwithstanding any other provisions of this Certificate of
Incorporation or the Bylaws of the Corporation (and notwithstanding the fact
that some lesser percentage may be

                                       -3-

<PAGE>



specified by law, this certificate of incorporation or the by-laws of the
Corporation), the affirmative vote of the holders of seventy percent (70) or
more of the outstanding shares of capital stock of the Corporation entitled to
vote generally in the election of directors (considered for this purpose as one
class) shall be required to amend, alter, change or repeal this Article V.

                                   ARTICLE VI

                  1.(A) In addition to any affirmative vote required by law or
this Certificate of Incorporation, and except as otherwise expressly provided in
paragraph 2 of this Article VI:

                  (i) any merger or consolidation of the Corporation or any
Subsidiary (as hereinafter defined) with (a) any Interested Stockholder (as
hereinafter defined) or (b) any other corporation (whether or not itself an
Interested Stockholder) which is, or after such merger or consolidation would
be, an Affiliate (as hereinafter defined) of an Interested Stockholder; or

                  (ii) any sale, lease, exchange, mortgage, pledge, transfer or
other disposition (in one transaction or a series of transactions), to or with
any Interested Stockholder or any Affiliate of any Interested Stockholder, of
any assets of the Corporation or any Subsidiary having an aggregate Fair Market
Value (as hereinafter defined) of $1,000,000 or more; or

                  (iii) the issuance or transfer by the Corporation or any
Subsidiary (in one transaction or a series of transactions) of any securities of
the Corporation or any Subsidiary to any Interested Stockholder or any Affiliate
of any Interested Stockholder in exchange for cash, securities or other property
(or a combination thereof) having an aggregate Fair Market Value of $l,000,000
or more; or

                  (iv) the adoption of any plan or proposal for the liquidation
or dissolution of the Corporation proposed by or on behalf of an Interested
Stockholder or any Affiliate of any Interested Stockholder; or

                  (v) any reclassification of securities (including any reverse
stock split), or recapitalization of the Corporation, or any merger or
consolidation of the Corporation with any of its Subsidiaries or any other
transaction (whether or not with or into or otherwise involving an Interested
Stockholder) which has the effect, directly or indirectly, of increasing the
proportionate share of the outstanding shares of any class of equity or
convertible securities of the Corporation or any Subsidiary which is directly or
indirectly owned by any Interested Stockholder or any Affiliate of any
Interested Stockholder; shall require the affirmative vote of the holders of at
least eighty percent (80%) of the then outstanding shares of each class of the
capital stock of the Corporation (the "Voting Stock"). Such affirmative

                                       -4-

<PAGE>



vote shall be required notwithstanding the fact that no vote may be required, or
that a lesser percentage may be specified, by law or in any agreement with any
national securities exchange or otherwise. Notwithstanding any other provision
of this certificate of incorporation to the contrary, for purposes of this
Article VI, each share of the Voting Stock shall have one vote.

         (B) The term "Business Combination" as used in this Article VI shall
mean any transaction which is referred to in any one or more of clauses (i)
through (v) of sub-paragraph (A) of this paragraph l.

         2. The provisions of paragraph 1 of this Article VI shall not be
applicable to any particular Business Combination, and such Business Combination
shall require only such affirmative vote as is required by law and any other
provision of this certificate of incorporation, if all of the conditions
specified in either of the following sub-paragraphs (A) and (B) are met:

         (A) The Business Combination shall have been approved by a majority of
the Continuing Directors (as hereinafter defined); provided, however, that such
approval shall only be effective if obtained at a meeting at which a Continuing
Director Quorum (as hereinafter defined) is present.

         (B)      All of the following conditions shall have been met:

                  (i) The aggregate amount of (x) cash and (y) Fair Market Value
as of the date of the consummation of the Business Combination of consideration
other than cash, to be received per share by holders of each class of the
Corporation's capital stock in such Business Combination shall be at least equal
to the highest amount determined under sub-clauses (a), (b) and (c) below:

                           (a) (if applicable) the highest per share price
(including any brokerage commissions, transfer taxes and soliciting dealers'
fees) paid by the Interested Stockholder for any share of such class acquired by
it (l) within the two-year period immediately prior to the first public
announcement of the proposal of the Business Combination (the "Announcement
Date") or (2) in the transaction in which it became an Interested Stockholder,
whichever is higher;

                           (b) the Fair Market Value per Share of such class on
the Announcement Date or on the date on which the Interested Stockholder became
an Interested Stockholder (such latter date is referred to in this Article VI as
the "Determination Date"), whichever is higher; and

                           (c) (if applicable) the highest preferential amount
per share to which the holders of shares of such class would be entitled in the
event of any voluntary or

                                       -5-

<PAGE>



involuntary liquidation, dissolution or winding up of the affairs of the
Corporation, regardless of whether the Business Combination to be consummated
constitutes such an event.

                  (ii) The consideration to be received by holders of a
particular class of outstanding Voting Stock shall be in cash or in the same
form as the Interested stockholder has previously paid for shares of such class
of Voting Stock. If the Interested Stockholder has paid for shares of any class
of Voting Stock with varying forms of consideration, the form of consideration
for such class of Voting Stock shall be either cash or the form used to acquire
the largest number of shares of such class of Voting Stock previously acquired
by it. If the Interested Shareholder shall not have previously acquired shares
of a particular class, the form of consideration to be received by holders of
such class shall be cash.

                  (iii) After such Interested Stockholder has become an
Interested Stockholder, such Interested Stockholder shall not have received the
benefit, directly (except proportionately as a stockholder), of any loans,
advances, guarantees, pledges or other financial assistance or any tax credits
or other tax advantages provided by the Corporation, whether in anticipation of
or in connection with such Business Combination or otherwise.

                  (iv) A proxy or information statement describing the proposed
Business Combination and complying with the requirements of the Securities
Exchange Act of 1934 and the rules and regulations thereunder (or any subsequent
provisions replacing such Act, rules or regulations) shall be mailed to public
stockholders of the Corporation at least 30 days prior to the consummation of
such Business Combination (whether or not such proxy or information statement is
required to be mailed pursuant to such Act or subsequent provisions).

                  3.       For the purposes of this Article VI:

                  (A) The term "person" shall mean any individual, firm,
corporation or other entity.

                  (B) The term "Interested Stockholder" shall mean any person
(other than the Corporation or any Subsidiary and other than any profit-sharing,
employee stock ownership or other employee benefit plan of the Corporation or
any Subsidiary or any trustee of or fiduciary with respect to any such plan when
acting in such capacity) who or which:

                           (i) is the beneficial owner (as hereinafter defined)
of more than twenty percent (20%) of the Voting Stock; or

                           (ii) is an Affiliate (as hereinafter defined) of the
Corporation and at any time within the two-year period immediately prior to the
date in question was the beneficial owner of twenty percent (20%) or more of the
Voting Stock; or


                                       -6-

<PAGE>



                           (iii) is an assignee of or has otherwise succeeded to
any shares of Voting Stock which were at any time within the two-year period
immediately prior to the date in question beneficially owned by any Interested
Stockholder, if such assignment or succession shall have occurred in the course
of a transaction or series of transactions not involving a public offering
within the meaning of the Securities Act of 1933;

provided, that no person which prior to October 24, 1996 came within the
definition set forth in this sub-paragraph (B), nor any present or future
Affiliate of such a person, shall be considered an Interested Stockholder.

         (C) A person shall be a "beneficial owner" of any Voting Stock:

                  (i) which such person or any of its Affiliates or Associates
(as hereinafter defined) beneficially owns, directly or indirectly; or

                  (ii) which such person or any of its Affiliates or Associates
has, directly or indirectly (a) the right to acquire (whether such right is
exercisable immediately or only after the passage of time), pursuant to any
agreement, arrangement or understanding or upon the exercise of conversion
rights, exchange rights, warrants or options, or otherwise, or (b) the right to
vote pursuant to any agreement, arrangement or understanding; or

                  (iii) which are beneficially owned, directly or indirectly, by
any other person with which such person or any of its Affiliates or Associates
has any agreement, arrangement or understanding for the purpose of acquiring,
holding, voting or disposing of any shares of Voting Stock.

                  (D) For the purposes of determining whether a person is an
Interested Stockholder pursuant to sub-paragraph (B) of this paragraph 3, the
number of shares of Voting Stock deemed to be outstanding shall include shares
deemed owned through application of subparagraph (C) of this paragraph 3 but
shall not include any other shares of Voting Stock which may be issuable
pursuant to any agreement, arrangement or understanding or upon exercise of
conversion rights, warrants or options, or otherwise.

                  (E) The terms "Affiliate" and "Associate" shall have the
respective meanings ascribed to such terms in Rule l2b-2 of the General Rules
and Regulations under the Securities Exchange Act of 1934, as in effect on
October 24, 1996.

                  (F) The term "Subsidiary" means any corporation of which a
majority of any class of equity security is owned, directly or indirectly, by
the Corporation; provided, however, that for the purposes of the definition of
Interested Stockholder set forth in subparagraph (B) of this paragraph 3, the
term "Subsidiary" shall mean only a corporation of which a majority of each
class of equity security is owned, directly or indirectly, by the Corporation.

                                       -7-

<PAGE>




                  (G) The term "Continuing Director" means any member of the
Board of Directors of the Corporation who is unaffiliated with the Interested
Stockholder and was a member of the Board prior to the time that the Interested
Stockholder became an Interested Stockholder, and any successor of a Continuing
Director who is unaffiliated with the Interested Stockholder and is recommended
or elected to succeed a Continuing Director by a majority of Continuing
Directors, provided that such recommendation or election shall only be effective
if made at a meeting at which a Continuing Director Quorum is present.

                  (H) The term "Continuing Director Quorum" means three
Continuing Directors capable of exercising the powers conferred upon them under
the provisions of the Certificate of Incorporation or By-Laws of the Corporation
or by law.

                  (I) The term "Fair Market Value" means: (i) in the case of
stock, the highest closing sale price during the 30-day period immediately
preceding the date in question of a share of such stock on the principal United
States securities exchange registered under the Securities Exchange Act of 1934
on which such stock is listed, or, if such stock is not listed on any such
exchange, the highest closing bid quotation with respect to a share of such
stock during the 30-day period preceding the date in question on the National
Association of Securities Dealers, Inc. Automated Quotations System or any
system then in use, or if no such quotations are available, the fair market
value on the date in question of a share of such stock as determined by the
Board in good faith; and (ii) in the case of property other than cash or stock,
the fair market value of such property on the date in question as determined in
good faith by a majority of Continuing Directors, provided that such
determination shall only be effective if made at a meeting at which a Continuing
Director Quorum is present.

                  (J) In the event of any Business Combination in which the
Corporation survives, the phrase "other consideration to be received" as used in
sub-paragraphs (B)(i) and (ii) of paragraph 2 of this Article VI shall include
the shares of Common Stock and/or the shares of any other class of Voting Stock
retained by the holders of such shares.

         4. The Board of Directors shall have discretion to interpret the
meaning of the provisions of this Article VI, and their applicability with
respect to various factual situations, and the determinations of the Board in
such regard shall be conclusive and binding.

         5. Nothing contained in this Article VI shall be construed to relieve
any Interested Stockholder from any fiduciary obligation imposed by law.

         6. Notwithstanding any other provisions of this Certificate of
Incorporation or the By-laws of the Corporation (and notwithstanding the fact
that a lesser percentage may be specified by law, this certificate of
incorporation or the by-laws of the Corporation), the affirmative vote of the
holders of eighty percent (80%) or more of the outstanding shares of each class
of Voting Stock shall be required to amend or repeal, or adopt any provisions
inconsistent with, this Article VI.

         Section 2. The Corporation shall indemnify any person who was or is a
party or is threatened to be made a party to any third party proceeding by
reason of the fact that he or she was or is a corporate agent, against his or
her expenses and liabilities in connection with such third party proceeding if
he or she acted in good faith and in a manner reasonably believed by him or her
to be in, or not opposed to, the best interests of the Corporation and, with
respect to any criminal third party proceeding, had no reasonable cause to
believe his or her conduct was unlawful. The termination of any third party
proceeding by judgment, order, settlement, consent, filing of a criminal
complaint or information, indictment, conviction or upon a plea of nolo
contendere or its equivalent, shall not, of itself, create a presumption that
the person did not act in good faith and in a manner which he or she reasonably
believed to be in, or not opposed to, the best interests of the Corporation or,
with respect to any criminal third party proceeding, had reasonable cause to
believe that his or her conduct was unlawful.

         Section 3. The Corporation shall indemnify any person who was or is a
party or is threatened to be made a party to any derivative action by reason of
the fact that such person was or is a corporate agent, against his or her
expenses with the defense or settlement of such action if he or she acted in
good faith and in a manner reasonably believed by him or her to be in, or not
opposed to, the best interests of the Corporation; except that no
indemnification shall be made in respect of any claim, issue or matter as to
which he or she shall have been adjudged to be liable to the Corporation unless
and only to the extent that the Delaware Court of Chancery or the court in which
such derivative action is or was brought shall determine upon application that,
despite the adjudication of liability but in view of all circumstances of the
case, he or she is fairly and reasonably entitled to indemnity for such items
which the court shall deem proper.

         Section 4. To the extent that any corporate agent has been successful
on the merits or otherwise in defense of any third party proceeding or
derivative action or in defense of any claim, issue or matter therein, the
corporate agent shall be indemnified against his or her expenses in connection
therewith.

         Section 5. Indemnification under Sections 2 and 3 of this Article Ten
(unless ordered by a court, in which case the expenses of the corporate agent in
enforcing indemnification shall be added to and be included in the final
judgment against the Corporation) shall be made by the Corporation only as
authorized in the specific case upon a determination that indemnification of the
corporate agent is required or proper in the circumstances because he or she has
met the applicable standard of conduct set forth in Section 2 or 3 of this
Article Ten or has been successful on the merits or otherwise as set forth in
Section 4 of this Article X and that the amount requested has been actually and
reasonably incurred. Such determination shall be made:

                  a. By the board of directors, acting by a majority vote of a
quorum consisting of directors who were not parties to the third party
proceeding or derivative action, or

                                       18

<PAGE>



                  b. If such a quorum is not obtainable or, even if obtainable a
quorum of disinterested directors so directs, by independent legal counsel in a
written opinion, or

                  c. By the shareholders.

         Section 6. Expenses incurred in defending a third party proceeding,
criminal third party proceeding or derivative action shall be paid on behalf of
a corporate agent, by the Corporation in advance of the final disposition of
such actions upon receipt of an undertaking by or on behalf of such person to
repay such amount unless it shall ultimately be determined that he or she is
entitled to be indemnified by the Corporation as required in this Article Ten.

         Section 7. The Corporation shall have the power to purchase and
maintain insurance on behalf of any person who is or was a corporate agent
against any expenses and liabilities asserted against him or her and incurred by
him or her by reason of his or her being or having been a corporate agent,
whether or not the Corporation would have the power to indemnify him or her
against such expenses and liabilities under the provisions of this Article Ten.

         Section 8. Each person who shall act as a corporate agent shall be
deemed to be doing so in reliance upon the rights of indemnification provided in
this Article.

                  The indemnification provided by this Article shall not be
deemed exclusive of any other right to which a person seeking indemnification or
advancement of expenses may be entitled under any statute, by-law, agreement,
vote of shareholders or disinterested directors, or otherwise, regardless of
whether the event giving rise to indemnification occurred before or after the
effectiveness thereof, both as to action taken in the official capacity of such
person and as to action in another capacity while holding his or her office or
position, and shall continue as to a person who has ceased to be a corporate
agent and shall inure to the benefit of his or her heirs and personal
representatives.

                             CERTIFICATES FOR SHARES

         Section 1. Every holder of stock in the Corporation shall be entitled
to have a certificate, signed by, or in the name of the Corporation by, the
Chairman of the Board, the vice chairman or the president or a vice-president,
and by the treasurer or an assistant treasurer, or the secretary or an assistant
secretary of the Corporation, certifying the number of shares owned by him in
the Corporation.

         When the Corporation is authorized to issue shares of more than one
class, there shall be set forth upon the face or back of the certificate, or the
certificate shall have a statement that the Corporation will furnish to any
shareholder upon request and without charge, a full statement of the
designations, preferences, limitations and relative rights of the shares of each
class authorized to be issued and, if the Corporation is authorized
to issue any preferred or special class in series, the variations in the
relative rights and preferences between the shares of each such series so far as
the same have been fixed and determined and the authority of the board of
directors to fix and determine the relative rights and preferences of subsequent
series.

         Section 2. The signatures of the officers of the Corporation upon a
certificate may be facsimiles if the certificate is countersigned by a transfer
agent, or registered by a registrar, other than the Corporation itself or an
employee of the Corporation. In case any officer who has signed or whose
facsimile signature has been placed upon such certificate shall have ceased to
be such officer before such certificate is issued, it may be issued by the
Corporation with the same effect as if he were such officer at the date of its
issue.

                                LOST CERTIFICATES

         Section 3. The board of directors may direct a new certificate to be
issued in place of any certificate theretofore issued by the Corporation alleged
to have been lost or destroyed. When authorizing such issue of a new
certificate, the board of directors, in its discretion and as a condition
precedent to the issuance thereof, may prescribe such terms and conditions as it
deems expedient, and may require such bonds or indemnities as it deems adequate,
to protect the Corporation from any claim that may be made against it with
respect to any such certificate alleged to have been lost or destroyed.

the Corporation of a certificate representing shares duly endorsed or
accompanied by proper evidence of succession, assignment or authority to

the old certificate cancelled and the transaction recorded upon the books of the

           Employment is "at will" which means that either the Company or

           reason.

           a)     The Company may terminate other than for "cause" at any time
                  upon written notice to Employee. In such case, the Company
                  will continue to pay Employee's annual salary for a period of
                  one year following such termination. The Company will have no
                  other obligation and no other severance pay or other benefits
                  will be provided.

           b)     The Company may terminate employment for cause at any time
                  upon written notice setting forth the nature of such cause.
                  The following, as determined by the Company in its reasonable
                  judgment, shall constitute "cause" for termination:

                  (1)    Employee's failure to perform duties and 
                         responsibilities as outlined in the job description
                         dated October, 1996 or as amended thereafter.
                  (2)    Any Employee misconduct which is injurious to the 
                         business or interests of the Company. 
                  (3)    Violation of any federal, state, or local law 
                         applicable to the business of the Company. 
                  (4)    Any material breach of this agreement.

           c)     Employee may terminate employment at any time, with or without
                  good reason, upon 90 days written notice to the Company.

           d)     If Employee resigns or employment is terminated by the Company
                  for cause, the Company shall have no further obligation to
                  Employee other than for annual salary earned through the date
                  of termination.

           b)     In the event that any provision of this Agreement is held to

                  limitation the geographic or business scope or duration

                  provision had been more narrowly drawn so as not to be invalid

           c)     This Agreement supersedes all prior agreements, arrangements,
                  and understandings, written or oral, relating to the subject
                  matter.

        exercisable 180 days following an initial public offering if it occurs
        within seven years from the date of grant and will remain exercisable
        for a five year period. In addition, the option becomes exercisable for
        a one month period upon the sale of a majority interest in the business
        if it occurs before an IPO and within seven years from the date of
        grant.

4.      Directors may exercise their options by payment in cash or stock of
        Premier.

5.      Termination of options - options terminate within one month of a Board
        member's resignation or removal from office.

                           Sale: Any sale of substantially all the assets of the
Company, other than in the ordinary course of business, or a sale or transfer of
the  capital  stock of the  Company  (other  than in the IPO)  resulting  in the
majority of the voting capital stock of the Company being owned by other than UM
or its  affiliates.  Whether an event  constitutes a "sale"  hereunder  shall be
subject to the reasonable determination of the Committee.

                           UM:  UM Holdings, Ltd. and its subsidiaries.

         3. Stock Subject to Plan. Subject to adjustment as hereinafter
provided, options to purchase up to an aggregate of 500 shares of the Company's
Common Stock may from time to time be granted by the Company pursuant to this
Plan. Shares that by reason of the expiration of an option or otherwise are no
longer subject to purchase pursuant to an option granted under the Plan may be
re-optioned under the Plan.

         4.       Administration.

                  (a) The Plan shall be administered by a Committee consisting
of not less than two directors (the "Committee") to be appointed from time to
time by the Board of Directors. Membership on the Committee shall in any event
be limited to those members of the Board who are "disinterested persons" as
defined in the regulations promulgated by the Securities Exchange Commission
pursuant to Section 16(b) of the Securities Exchange Act of 1934.
Notwithstanding the foregoing, the Board of Directors may choose to directly
administer the Plan, provided that all members of the Board are at such time
"disinterested persons." During any such period of direct administration of the
Plan by the Board of Directors, all references herein to the Committee shall
instead mean the Board of Directors.

                  (b) The Committee shall have full power to grant options under
the Plan, to construe or interpret the Plan, to prescribe, amend and rescind
rules and regulations relating to it and to make all other determinations
necessary or advisable for its administration. The decisions of the Committee
shall be conclusive and final.

                  (c) The Committee may, from time to time, determine which
participants shall be granted options under the Plan, the number of Option
Shares subject to each option, and the time or times at which options shall be
granted.

                  (d) The Committee shall report to the Board of Directors the
names of participants to be granted options and the number of Option Shares
subject to, and the terms and conditions of, each option.

<PAGE>


                  (e) The members of the Board of Directors and the Committee
shall not be liable for any action or determination made in good faith with
respect to the Plan or to any option.

         5. Eligibility; Grant of Options. (a) Participants. The persons who
shall be eligible to participate in this Plan and receive options hereunder
shall be such employees and other individuals who provide services to or
otherwise have a relationship with the Company or UM as the Committee shall from
time to time determine to be key individuals to the success of the Company. Each
employee granted an option shall, on or before the date of the grant, enter into
an appropriate employment agreement.

                  (b) Grants of Options. The Committee may from time to time, up
to the day immediately preceding the IPO Date, authorize the grant of options
pursuant to this Plan to one or more persons eligible to participate in the
Plan, each of which options shall be on such terms and conditions, consistent
with this Plan (including as specified in paragraph 7 below), as may be
specified by the Committee.

         6. Stock Option Agreements. Stock options granted pursuant to this Plan
shall be evidenced by agreements which shall comply with and be subject to the
terms and conditions specified in this Plan. Nothing in this Plan or an option
granted hereunder shall govern the employment rights and duties between the
optionee and the Company or UM. Neither this Plan, nor any grant or exercise
pursuant thereto, shall constitute an employment agreement among such parties.

         7. Terms and Conditions. Each option granted hereunder shall be subject
to the following terms and conditions:

                  (a) Option Price.  The option price shall equal the Base Price
as in effect on the date of grant.

                  (b)  Date  First   Exercisable.   Each  option   shall  become
exercisable in full on the first to
occur of (i) the ninetieth day following the IPO Date or (ii) July 1, 2003.

                  (c) Term. Each option shall expire (i) if the IPO occurs prior
to July 1, 2003,  on the fifth  anniversary  of the IPO Date, or (ii) August 15,
2003, in the event the IPO has not occurred  prior to July 1, 2003, in each case
subject to early  termination  as otherwise  provided in this Plan or the option
agreement.

                  (a) Manner of Exercise. Shares of Common Stock purchased upon
exercise of options shall at the time of purchase be paid for in full. To the
extent that the right to purchase shares has accrued hereunder, options may be
exercised from time to time by written notice to the Company stating the full
number of shares with respect to which the option is being exercised and the
time of delivery thereof, in accordance with such administrative procedures as
may from time to time be specified by the Committee. Such notice of exercise
shall be accompanied by full payment for the shares by certified or official
bank check or the equivalent thereof acceptable to Company or by tendering to
the Company shares of the Common Stock having an aggregate fair market value,
determined by the Company at the date of payment, equal to the option price and
which shall have been owned by the optionee for at least six months. Upon
exercise, the Company shall deliver to the optionee (or to such other person
entitled to exercise the option) at the principal office of the Company, or such
other place as shall be mutually agreed upon, a certificate or certificates for
such shares; provided, however, that the time of delivery may be postponed by
the Company for such period as may be required for it with reasonable diligence
to comply with any requirements of law; and provided further that in the event
the Common Stock issuable upon exercise is not registered under the Securities
Act of 1933 (the "Act"), then the Company may require that the registered owner
deliver an investment representation in form acceptable to the Company and its
counsel and the Company will place a legend on the certificate for such Common
Stock restricting the transfer of same. There shall be no obligation or duty for
the Company to register under the Act at any time the Common Stock issuable upon
exercise of the options. If optionee (or other person entitled to exercise the
option) fails to accept delivery, the optionee's payment shall be returned and
the right to exercise the option with respect to such undelivered shares shall
be terminated.

                  (b)  Non-Assignability  of Option  Rights.  No option shall be
assignable or transferable  otherwise than by will or by the laws of descent and
distribution.

                  (c) Termination of Employment. For purposes of this Plan, the
term "termination of employment" refers generally to an individual ceasing to be
an employee or independent contractor of the Company or UM. Options granted
hereunder to individuals who, at the time of grant, are employees of the Company
or UM shall terminate upon a termination of employment in accordance with the
following provisions:

                           (i)  Upon  the   termination   of  employment  of  an
optionee,  all  options  granted  to the  optionee  pursuant  to this Plan shall
terminate  three months after the date of termination  of employment,  except to
the extent the provisions of clause (ii) below are applicable.

                                     - 4 -

<PAGE>


                           (ii) Solely in the event that the termination of
employment occurs prior to the first to occur of (A) August 15, 2003 or (B) the
IPO Date, due to (1) the optionee's death or Permanent Disability or (2) the
termination of employment by the Company other than for due cause, the optionee
or his estate shall have the right to exercise any option (to the extent
otherwise exercisable) within twenty-four months after the date of termination
of employment. At the end of such twenty-four month period, the option shall
terminate. For purposes of this clause (ii), a termination shall be deemed "for
due cause" if the Company or UM determines that the optionee has committed any
act of dishonesty, or has materially breached any corporate policy or any
agreement between the optionee and his employer, or has failed to adequately
perform assigned duties and responsibilities.

                  (d) Adjustment of Options on Recapitalization. The aggregate
number of shares of Common Stock for which options may be granted to persons
participating under the Plan, the Base Price, the IPO Price, the number of
shares covered by each outstanding option and the exercise price per share for
each such option, shall be proportionately adjusted for any increase or decrease
in the number of issued shares of Common Stock of the Company resulting from the
subdivision or consolidation of shares, or the payment of a stock dividend after
the effective date of this Plan or the date of grant, as applicable, or other
increase or decrease in such shares effected without receipt of consideration by
the Company; provided, however, that any options to purchase fractional shares
resulting from any such adjustment shall be eliminated.

                  (e) Adjustment of Options Upon Reorganization. Except as
otherwise provided in subparagraph (g) below, if the Company shall at any time
merge or consolidate with or into another corporation and (A) the Company is not
the surviving entity, or (B) the Company is the surviving entity and the holders
of Company Common Stock are required to exchange their shares for property
and/or securities, the holder of each option will thereafter receive, upon the
exercise thereof, the securities and/or property to which a holder of the number
of shares of Common Stock then deliverable upon the exercise of such option
would have been entitled upon such merger or consolidation, and the Company
shall take such steps in connection with such merger or consolidation as may be
necessary to assure that the provisions of this Plan shall thereafter be
applicable, as nearly as reasonably may be, in relation to any securities or
property thereafter deliverable upon the exercise of such option, provided,
however that under no circumstance shall any option exercise date be accelerated
in contemplation of such action. A sale of all or substantially all the assets
of the Company for a consideration (apart from the assumption of obligations)
consisting primarily of securities shall be deemed a merger or consolidation for
the foregoing purposes.

<PAGE>


                  (f) Dissolution of Company. Except as otherwise provided in
subparagraph (g) below, in the event of the proposed dissolution or liquidation
of the Company, the options granted hereunder shall terminate as of a date to be
fixed by the Committee, provided that not less than thirty (30) days' prior
written notice of the date so fixed shall be given to the optionee, and the
optionee shall have the right, during the period of thirty (30) days preceding
such termination, to exercise the option, if the option is otherwise then
exercisable.

                  (g) Sale Prior to IPO. Notwithstanding the provisions of
subparagraph (e) or (f) above, and in substitution thereof, in the event that a
Sale of the Company occurs prior to the earlier to occur of the IPO Date or
August 15, 2003, each outstanding option shall terminate and in its place each
optionee shall have the right to receive, not later than ninety days following
the date of the closing of such Sale, an amount equal to (i) the effective sale
price per share in the Sale, minus (ii) the exercise price of the option, all
multiplied by (iii) the number of Option Shares represented by such option. The
amount, if any, so due to an optionee shall be calculated by the Company's
independent auditors, which determination shall be conclusive, final and binding
on all parties. This amount shall be payable in cash, unless the consideration
received in the Sale includes non-cash consideration, in which case the Company
may choose to satisfy this obligation by delivering to the optionee the same
type of consideration as that received in the Sale.

                  (h) Rights as a Shareholder. The optionee shall have no rights
as a shareholder with respect to any shares of Common Stock of the Company held
under option until the date of issuance of the stock certificates to him for
such shares. Except as provided in subparagraph (d) above, no adjustment shall
be made for dividends or other rights for which the record date is prior to the
date of such issuance.

         8.       Effective Date and Termination.

                  (a) The effective date of the Plan is August 15, 1993.

                  (b) The Plan shall terminate on November 15, 2003, but the
Board of Directors may terminate the Plan at any time prior thereto. Termination
of the Plan shall not alter or impair, without the consent of the optionee, any
option theretofore granted, or any other right or obligation then existing,
under the Plan.

         9. Amendments. The Board of Directors of the Company may, from time to
time, alter, amend, suspend, or discontinue the Plan, or alter or amend any and
all option agreements granted thereunder; provided, that no such action of the
Board of Directors, without the approval of the shareholders of Company and, in
the case of subparagraph (c), the holder of the option, may alter the provisions
of the Plan so as to:

                  (a) Extend the term of the Plan or the maximum term of the
options granted beyond that specified by the Plan;

                  (b) Withdraw the administration of the Plan from the Board of
Directors and the Committee;

                  (c) Alter any outstanding option agreement to the detriment of
the optionee.

         10. Options Not Incentive Stock Options. Options granted pursuant to
this Plan are not intended to qualify as Incentive Stock Options within the
meaning of Section 422 of the Code, and the terms of this Plan and options
granted hereunder shall be so construed.

         11. Use of Proceeds. The proceeds from the sale of Common Stock
pursuant to the exercise of options will be used for the Company's general
corporate purposes.

                        PREMIER RESEARCH WORLDWIDE, LTD.

                             1996 STOCK OPTION PLAN

1.       Purpose

         The purpose of the 1996 Stock Option Plan (referred to herein as the
"Plan") of Premier Research Worldwide, Ltd. (the "Company") is to provide a
means by which certain employees and directors of, and others providing services
to or having a relationship with, the Company and its subsidiaries (as such term
is defined in Section 424(f) of the Internal Revenue Code of 1986, as amended
(the "Code")) may be given an opportunity to purchase common stock of the
Company ("Common Stock"). The Plan is intended to promote the interests of the
Company by encouraging stock ownership on the part of such individuals, by
enabling the Company and its subsidiaries to secure and retain the services of
highly qualified persons, and by providing such individuals with an additional
incentive to advance the success of the Company and its subsidiaries.


2.       Administration

         The Plan shall be administered by a Committee consisting of not less
than two directors (the "Committee") to be appointed from time to time by the
Board of Directors. Membership on the Committee shall in any event be limited to
those members of the Board who are "Non-Employee Directors" as defined in the
regulations promulgated by the Securities Exchange Commission pursuant to
Section 16(b) of the Securities Exchange Act of 1934. The Committee shall have
the power to select optionees, to establish the number of shares and other terms
applicable to each such option, to construe the provisions of the Plan, and to
adopt rules and regulations governing the administration of the Plan. All power
and authority granted hereunder to the Committee may, at the discretion of the
Board of Directors, be exercised by the Board. The members of the Board of
Directors or the Committee shall not be liable for any action or determination
made in good faith with respect to the Plan or to any option granted pursuant
thereto.


3.       Eligibility

         The persons who shall be eligible to participate in this Plan and
receive options hereunder shall be the Company's directors and such employees
and other individuals who provide services to or otherwise have a relationship
with the Company or its subsidiaries as the Committee shall from time to time
determine to be key individuals to the success of the Company.


<PAGE>

4.       Allotment of Shares

         A maximum of 500,000 authorized but unissued shares of the Common
Stock, $0.01 par value, of the Company will be allotted to the Plan. Shares that
by reason of the expiration of an option or otherwise are no longer subject to
purchase pursuant to an option granted under the Plan may be re-optioned under
the Plan.


5.       Effective Date and Term of Plan

         The effective date of the Plan is the date on which it is approved by
the affirmative vote of shareholders owning a majority of the Common Stock of
the Company. The Plan shall terminate on the tenth anniversary of its effective
date, but the Board of Directors may terminate the Plan at any time prior
thereto. Termination of the Plan shall not alter or impair, without the consent
of the optionee, any of the rights or obligations of any option theretofore
granted under the Plan.


6.       Terms and Conditions

         A.       All Options

                  Stock options granted pursuant to this Plan shall be evidenced
by agreements in such form as the Committee shall from time to time approve.
Nothing in this Plan or any option granted hereunder shall govern the employment
rights and duties between the optionee and the Company or subsidiary. Neither
this Plan, nor any grant or exercise pursuant thereto, shall constitute an
employment agreement among such parties. The following shall also apply to all
options granted under the Plan:

                  (i)      Option Price

                           The option price per share for each stock option
                  shall be determined by the Committee, consistent with the
                  provisions of this Plan.

                  (ii)     Time of Exercise of Option

                           Except as otherwise set forth herein, the Committee
                  shall establish the option period and time or times within the
                  option period when the stock option may be exercised in whole
                  or in such parts as may be specified from time to time by the
                  Committee. No option shall be exercisable until after the
                  expiration of six months from the date of grant. With respect
                  to an optionee who is about to retire, the Committee may in
                  its discretion accelerate the time or times when any
                  particular stock option held by said optionee may be so
                  exercised so that such time or times are earlier than those 
                  originally provided in said option. In all cases exercise of 
                  a stock option shall be subject to the provisions of Section
                  6A(vi).

                  (iii)    Payment and Manner of Exercise

                                       2

<PAGE>

                           The entire option price shall be paid at the time the
                  option is exercised. To the extent that the right to purchase
                  shares has accrued hereunder, options may be exercised from
                  time to time by written notice to the Company stating the full
                  number of shares with respect to which the option is being
                  exercised and the time of delivery thereof, in accordance with
                  such administrative procedures as may from time to time be
                  specified by the Committee. Such notice of exercise shall be
                  accompanied by full payment for the shares by: (1) certified
                  or official bank check or the equivalent thereof acceptable to
                  Company; (2) by tendering to the Company shares of Common
                  Stock, or requesting the Company to accept shares to be
                  acquired by exercising the option, having an aggregate fair
                  market value, determined by the Company at the date of
                  payment, equal to the option price; or (3) any combination of
                  the foregoing. Upon exercise, the Company shall deliver to the
                  optionee (or other person entitled to exercise the option), at
                  the principal office of the Company, or such other place as
                  shall be mutually agreed upon, a certificate or certificates
                  for such shares; provided, however, that the time of delivery
                  may be postponed by the Company for such periods as may be
                  required for it with reasonable diligence to comply with any
                  requirements of law; and provided further that in the event
                  the Common Stock issuable upon exercise is not registered
                  under the Securities Act of 1933 (the "Act"), then the Company
                  may require that the registered owner deliver an investment
                  representation in form acceptable to the Company and its
                  counsel and the Company will place a legend on the certificate
                  for such Common Stock restricting the transfer of same. There
                  shall be no obligation or duty for the Company to register
                  under the Act at any time the Common Stock issuable upon
                  exercise of the options. If the optionee (or other person
                  entitled to exercise the option) fails to accept delivery, the
                  optionee's payment shall be returned and the right to exercise
                  the option with respect to such undelivered shares shall be
                  terminated.

                  (iv)     Non-Transferability of Option

                           An option by its terms shall not be transferable by
                  the optionee otherwise than by will or by the laws of descent
                  and distribution.

                  (v)      Adjustment in Event of Recapitalization of the 
                  Company

                           In the event of a reorganization, recapitalization,
                  stock split, stock dividend, combination of shares, merger,
                  consolidation, rights offering, or any other change in the
                  corporate structure or shares of the Company, the Board of
                  Directors shall make such adjustment as it may deem equitably
                  required, in the number and kind of shares authorized by and 
                  for the Plan, in the number and kind of shares covered by the
                  options granted, and in the option price.

                  (vi)     Rights after Termination of Employment

                                       3

<PAGE>

                           In the event of termination of employment due to any
                  cause other than death or disability, rights to exercise the
                  stock option shall terminate three months following cessation
                  of employment. In the event of termination of employment due
                  to disability (within the meaning of Section 22(e)(3) of the
                  Code) or death, such optionee or executor, administrator or
                  devisee of an optionee, shall have the right to exercise such
                  option (to the extent otherwise exercisable) at any time
                  within one year after cessation of employment by reason of
                  such disability or death.

         B.       Non-Qualified Stock Options

                  The Committee may, in its discretion, grant options under the
Plan which, in whole or in part, do not qualify as incentive stock options under
Section 422 of the Code ("Non-Qualifying Options"). The terms and conditions of
the Non-Qualifying Options shall be governed by Section 6A above.

         C.       Incentive Stock Options

                  The Committee may, in its discretion, grant options under the
Plan which qualify, in whole or in part, as incentive stock options under
Section 422 of the Code. In addition to the terms and conditions set forth in

         6.1. Except as may be otherwise permitted in this Article, the Tenant
covenants, for the Tenant and its successors, assigns and legal representatives,
that neither this Lease nor the term and estate hereby granted, nor any part
hereof or thereof, will be assigned, mortgaged, pledged, encumbered or otherwise
transferred, and that neither the Space, nor any part thereof, will be
encumbered in any manner by reason of any act or omission on the part of the
Tenant, or will be used or occupied, or permitted to be used or occupied, or

         6.4 This Lease and Tenant's interest herein is subject and subordinate
to all mortgages and underlying ground leases which may now or hereafter affect
the Space and to all renewals, modifications, amendments, consolidations,
replacements and extensions of any of the foregoing, provided Landlord secures
from the holder thereof an agreement, in form reasonably satisfactory to such
holder, providing that (i) so long as Tenant is not in default hereunder and
continues to observe all of the terms, covenants and conditions applicable to
Tenant, and (ii) provided Tenant shall attorn to such holder, it shall not
disturb the continued occupancy of Tenant under the terms hereof. Tenant, upon
the request of the holder of any such mortgage, shall execute and deliver to the
party requesting it an instrument in writing to the foregoing effect under which
Tenant agrees to attorn to such holder or to a purchaser of the mortgaged
premises in foreclosure. This clause shall be self-operative and no further
instrument of subordination shall be required. However, in confirmation of such
subordination, Tenant shall execute promptly any certificate consistent with the
foregoing terms that Landlord may reasonably request. The holder of any such
mortgage, now or hereafter having priority over this Lease, may subordinate same
to this Lease by notice to Tenant and without Tenant's consent and upon such
subordination, such holder shall have the same rights with respect to this Lease
as though this Lease had been executed and delivered prior to execution and
delivery of the mortgage and had been assigned by Landlord to such holder.


                                  ARTICLE SEVEN

         7.1. The Landlord reserves the right to make such changes, alterations,
additions, improvements, repairs or replacements in or to the Space and the
fixtures and equipment thereof, as well as in or to the street entrances, halls,
passages, elevators, and stairways and other parts of the Space, and to erect,
maintain and use pipes, ducts and conduits in and throughout the Space, as it
may reasonably deem necessary or desirable; provided, that the exercise of such
rights shall not result in an unreasonable obstruction of the means of access to
the Space or unreasonable interference with the use of the Space. Nothing in
this Section or in Article Five shall be deemed to relieve the Tenant of any
duty, obligation or liability to make any repair, replacement or improvement or
comply with any Requirement.


                                  ARTICLE EIGHT

(8.)     Damage by Fire, etc.

         8.1. In case of fire or other casualty, the Tenant shall give immediate
notice to the Landlord. If the premises shall be partially damaged by fire, the
elements or other casualty, the Landlord shall repair the same as speedily as
practicable, but the Tenant's obligation to pay the rent hereunder shall not
cease. If, in the opinion of the Landlord, the premises be so extensively and
substantially damaged as to render them untenantable, then the rent shall cease
until such time as the premises shall be made tenantable by the Landlord.
However, if in the opinion of the Landlord, the premises be totally destroyed or



                                       6
<PAGE>

so extensively and substantially damaged as to require practically a rebuilding
thereof, then the rent shall be paid up to the time of such destruction and then
and from thenceforth this lease shall come to an end. In no event, however,
shall the provisions of this clause become effective or be applicable, if the
fire or other casualty and damage shall be the result of the carelessness,
negligence or improper conduct of the Tenant or the Tenant's agents, employees,
guests, licensees, invitees, subtenants, assignees or successors. In such case,
the Tenant's liability for the payment of the rent and the performance of all
the covenants, conditions and terms hereof on the Tenant's part to be performed
shall continue and the Tenant shall be liable to the Landlord for the damage and
loss suffered by the Landlord. If the Tenant shall have been insured against any
of the risks herein covered, then the proceeds of such insurance shall be paid
over to the Landlord to the extent of the Landlord's costs and expenses to make
the repairs hereunder, and such insurance carriers shall have no recourse
against the Landlord for reimbursement.

         8.2 If the land and premises leased herein, or of which the leased
premises are a part, or any portion thereof, shall be taken under eminent domain
or condemnation proceedings, or if suit or other action shall be instituted for
the taking or condemnation thereof, or if in lieu of any formal condemnation
proceedings, the Landlord shall grant an option to purchase and/or shall sell
and convey the said premises or any portion thereof, to the governmental or
other public authority, agency, body or public utility, seeking to take said
land and premises or any portion thereof, then this lease, at the option of the
Landlord, shall terminate, and the term hereof shall end as of such date as the
Landlord shall fix by notice in writing; and the Tenant shall have no claim or
right to claim or be entitled to any portion of any amount for such option, sale
or conveyance in lieu of formal condemnation proceedings; and all rights of the
Tenant to damages, if any, are hereby assigned to the Landlord. The Tenant
agrees to execute and deliver any instruments, at the expense of the Landlord,
as may be deemed necessary or required to expedite any condemnation proceedings
or to effectuate a proper transfer of title to such governmental or other public
authority, agency, body or public utility seeking to take or acquire the said
lands and premises or any portion thereof. The Tenant covenants and agrees to
vacate the said premises, remove all the Tenant's personal property therefrom
and deliver up peaceable possession thereof to the Landlord or to such other
party designated by the Landlord in the aforementioned notice. Failure by the
Tenant to comply with any provisions in this clause shall subject the Tenant to
such costs, expenses, damages and losses as the Landlord may incur by reason of
the Tenant's breach hereof.

(9.)     Subsidiaries

given when delivered personally or by overnight mail service to such other party
and a receipt has been obtained or on the third day after being mailed in a

shall not duly institute and thereafter diligently prosecute to completion all
steps necessary to remedy the same, or (iii) shall not remedy the same within a
reasonable time after the date of the giving of said notice by the Landlord,
which period shall in no event exceed ninety (90) days;

                  (d) if any event shall occur or any contingency shall arise
whereby this Lease or the estate hereby granted or the unexpired balance of the
full term of this Lease would, by operation of law or otherwise, devolve upon or
pass to any person, firm or corporation other than the Tenant (except as
permitted under Article Six);

                  (e) when and to the extent permitted by law, if a petition in
bankruptcy shall be filed by or against the Tenant, or if the Tenant shall make
a general assignment for the benefit of its creditors, or the Tenant shall


                                       8
<PAGE>

receive the benefit of any insolvency or reorganization act, or if a receiver or
trustee is appointed for any portion of the Tenant's property and such
appointment is not vacated within sixty (60) days, or if an execution or
attachment shall be issued under which the Space shall be taken or occupied by
anyone other than the Tenant; then in any of said cases the Landlord may give to
the Tenant a notice of intention to end the term of this Lease, and, if such
notice is given, this Lease and the term and estate hereby granted (whether or
not the term shall theretofore have commenced) shall terminate upon the
expiration of three (3) days from the date of the notice is deemed given with
the same effect as if the last of said three (3) days were the date originally
specified as the expiration of the full term of this Lease, but the Tenant shall
remain liable for damages as provided in this Lease or pursuant to law. If this
Lease shall have been assigned, the term "Tenant", as used in subsections (a) to
(e), inclusive, of this Section 11.1 shall be deemed to include the assignee and
the assignor or either of them under any such assignment unless the Landlord
shall, in connection with such assignment, release the assignor from any further
liability under this Lease, in which event the term "Tenant", as used in said
subsections, shall not include the assignor so released.


                                 ARTICLE TWELVE

(12.)    Re-entry by Landlord

         12.1. If this Lease shall terminate under Article Eleven, or if the
Tenant shall default in the payment of any Rent on any date upon which the same
becomes due, and if such default shall continue for five (5) days after the
Landlord shall have given to the Tenant a notice specifying such default, the
Landlord or the Landlord's agents and servants may immediately or at any time
thereafter re-enter the Space, either by summary disposes proceedings or by any
suitable action or proceeding at law or by force (if permitted by law) or
otherwise, without being liable to indictment, prosecution or damages therefor,
and may repossess the same, and may remove any persons therefrom, to the end
that the Landlord may have, hold and enjoy Building again as and of its first
estate and interest therein. The words "re-enter", "re-entry", and "re-entering"
as used in this Lease are not restricted to their technical legal meanings.

         12.2. If this Lease shall terminate under the provisions of Article
Eleven or if the Landlord undertakes any summary dispossess or other proceeding
or action or other measure for the enforcement of its right of re-entry (any
such termination of this Lease or undertaking by the Landlord being a "Default
Termination"), the Tenant shall thereupon pay to the Landlord the Rent up to the
time of such Default Termination, and shall likewise pay to the Landlord all
such damages which, by reason of such Default Termination, shall be payable by
the Tenant as provided in this Lease or pursuant to law. Also in the event of a
Default Termination the Landlord shall be entitled to retain all moneys, if any,
paid by the Tenant to the Landlord whether as advance rent or security for rent,
but such moneys shall be credited by the Landlord against any Rent due from the
Tenant at the time of such Default Termination or, at the Landlord's option,
against any damages payable by the Tenant as provided in this Lease or pursuant
to law.



                                       9
<PAGE>

         12.3. In the event of a breach or threatened breach on the part of the
Tenant of any of its obligations under this Lease, the Landlord shall also have
the right of injunction. The specified remedies to which the Landlord may resort
under this Lease are cumulative and are not intended to be exclusive of any
other remedies or means of redress to which the Landlord may lawfully be
entitled at any time, and the Landlord may invoke any remedy allowed by law or
in equity as if specific remedies were not provided for in this Lease.


                                ARTICLE THIRTEEN

(13.)    Damages

         13.1 If there is a Default Termination of this Lease, the Tenant will
pay to the Landlord as damages sums equal to the aggregate of the fixed rent and
the additional rent, if any, which would have been payable by the Tenant had
this Lease not terminated by such Default Termination, payable upon the due
dates therefor specified in this Lease following such Default Termination and
until the date originally specified as the expiration of this Lease. In the
event that the Landlord shall have relet the premises and receive rents
therefor, it shall apply such rents first to the payment of such expenses,
reasonable attorney's fees and costs as may have been incurred in the
re-entering and repossessing the premises and in making such repairs and
alterations as may be necessary; and second to the payment of the rents due
hereunder.

         13.2 Nothing in this Lease shall be construed as limiting or precluding
the recovery by the Landlord against the Tenant of any sums or damages to which,
in addition to the damages specified above, the Landlord may lawfully be
entitled by reason of any default under this Lease on the part of the Tenant.


                                ARTICLE FOURTEEN

(14.)    Tenant's Removal

         14.1 Any personal property which shall remain in the Space after the
expiration or termination of the term of this Lease with respect to such part
shall be deemed to have been abandoned, and either may be retained by the
Landlord as its property or may be disposed of in such manner as the Landlord
may see fit at the Tenant's cost; provided, that the Tenant will, upon request
of the Landlord, remove from the Space any such personal property by the later
of the expiration or termination of this Lease or thirty (30) days after the
Landlord's request.

                                 ARTICLE FIFTEEN


(15.)    Lease Contains All Agreements-No Waivers

         15.1 This Lease contains all of the understandings relating to the
leasing of the Space and the Landlord's obligations in connection therewith and
neither the Landlord nor any agent or representative of the Landlord has made or
is making, and the Tenant in executing and delivering this Lease is not relying
upon, any warranties, representations, promises or statements whatsoever, except
to the extent expressly set forth in this Lease. All understandings and
agreements, if any, heretofore had between the parties are merged in this Lease,
which alone fully and completely expresses the agreement of the parties.

                                       10
<PAGE>

         15.2 The failure of either the Landlord or the Tenant to insist in any
instance upon the strict keeping, observance or performance of any provision of
this Lease or to exercise any election in this Lease shall not be construed as a
waiver or relinquishment for the future of such provision, but the same shall
continue and remain in full force and effect. No waiver or modification by
either the Landlord or the Tenant of any provision of this Lease shall be deemed
to have been made unless expressed in writing and signed by the Landlord or the
Tenant, as the case may be. No surrender of possession of the Space or of any
part thereof or of any remainder of the term of this Lease shall release the
Tenant from any of its obligations under this Lease unless accepted by the
Landlord in writing. The receipt and retention by the Landlord of Rent from
anyone other than the Tenant shall not be deemed a waiver of the breach by the
Tenant of any provision in this Lease, or the acceptance of such other person as
a tenant, or a release of the Tenant from its further observance of the
provisions of this Lease. The receipt and retention by the Landlord of Rent with
knowledge of the breach of any provision of this Lease shall not be deemed a
waiver of such breach.

         15.3 The Tenant agrees to permit the Landlord and Landlord's agents,
employees or other representatives to show the premises to persons wishing to
rent or purchase the same, and Tenant agrees that on and after 180 days next
preceding the expiration of the term hereof, the Landlord or its agents,
employees or other representatives shall have the right to place notices on the
front of said premises or any part thereof, offering the premises for rent or
for sale.

         15.4 If the Tenant shall fail or refuse to comply with and perform any
conditions and covenants of this lease, the Landlord may, in its discretion,
carry out and perform such conditions and covenants, at the cost and expense of
the Tenant, which shall be payable on demand. This remedy shall be in addition
to such other remedies as the Landlord may have hereunder by reason of the
breach by the Tenant of such covenants and conditions.

         15.5 The Tenant waives all rights of recovery against the Landlord or
Landlord's agents, employees or other representatives for any loss, damages or
injury of any nature whatsoever to property or persons for which the Tenant is
insured. The Tenant shall obtain from Tenant's insurance carriers and will
deliver to the Landlord waivers of the subrogation rights under the respective
policies.

The parties due hereby agree to all of the terms and provisions of this
Agreement which shall be governed under the laws of the State of Delaware.

                    Representation and Warranties of Premier
                    ----------------------------------------

         Premier hereby represents, warrants and covenants to RDW and the
Company as of the date hereof and the time of the Closing as follows:

         3.1 Seller's Organization, Etc. Premier is a corporation duly
organized, validly existing and in good standing under the laws of the State of
Delaware, is duly qualified as a foreign corporation in all jurisdictions
wherein the character of the property owned or leased or the nature of the
business transacted by it makes qualification as a foreign corporation
necessary, and has the corporate power to own its properties and carry on its
business.

         3.2 Corporate Authority; Etc. The execution, delivery and performance
by Premier of this Agreement and the Operating Agreement, the Assumption
Agreement, and the instruments described in paragraphs 6.3 below (collectively
with this Agreement, the "Acquisition Documents") have been duly authorized by
all necessary corporate action and will not violate any provision of law or of
Premier's Certificate of Incorporation or By-Laws or other constituent document,
or result in the breach of, or constitute a default under, or result in the
creation of any lien, charge or encumbrance upon any property or assets of
Premier pursuant to, any indenture, agreement or instrument to which Premier is
a party or by which Premier or any of its property may be bound or affected. The

                                       3
<PAGE>


Acquisition Documents have been or at Closing will be duly executed and
delivered by Premier and constitute or will constitute the legal, valid and
binding obligations of Premier, enforceable in accordance with their respective
terms.

         3.3 Financial and Other Data. Premier has delivered to Buyer copies of
the following financial statements (the "Financial Statements") of the Division:

             (i) A schedule of assets and liabilities as of July 31, 1995
("Schedule"); and

             (ii) Statements of income for the fiscal years ended December 31,
1992, 1993 and 1994 and for the six month period ended June 30, 1995.

                  Except as noted therein, the Financial Statements have been
prepared in accordance with generally accepted accounting principles
consistently applied throughout the periods indicated. The above-referenced
Schedule presents fairly in all material respects the assets and liabilities of
the Division as of its date, and the above-referenced statements of income
present fairly in all material respects the results of operations of the
Division for the periods covered thereby. Premier has disclosed and discussed
with RDW the incorrect matching of revenues and expenses which occurred at the
1993 fiscal year end cut-off which overstated operating profit for 1993, and the
operating loss for 1994, by approximately $800,000.

         3.4 Litigation, Etc. Except as set forth on Schedule 3.4, there is no
litigation, proceeding or governmental investigation pending or, to the best
knowledge of Premier, threatened against or relating to the Division, its
properties or business, or the transactions contemplated by this Agreement. The
consummation of the transactions contemplated by this Agreement will not require
the consent, approval, authorization or order of any court or governmental
authority and will not result in a violation of any Assumed Agreement. There are
no decrees, injunctions or orders of any court or governmental department or
agency regarding the Division, its properties or business of which Premier has
written notice or actual knowledge.

         3.5 Compliance with Laws. To the best of Premier's knowledge: Premier
has complied in all material respects with all federal, state, county, and local
laws, statutes, ordinances, rules, regulations, and orders (collectively, the
"Laws") relating to the Division or the Assets; the operation of Division's
business at its current locations is in conformity in all material respects with
all applicable zoning ordinances and regulations; and Premier has all licenses,
franchises, permits, certificates, authorizations, consents, licenses and
approvals required by law or any governmental authority or agency for (i) the
conduct of the Division's business as presently conducted, and (ii) the
execution, delivery or performance of this Agreement or any instrument
hereunder. Premier has not received notice and has no knowledge that it is in
default or noncompliance in any material respect under any of such permits,
certificates, consents, approvals, authorizations, orders, licenses, franchises
and/or other similar authority. To the best of Premier's knowledge, the
consummation of the transactions herein contemplated including, but not limited
to, the execution, delivery, and consummation of the Acquisition Documents, do
not, and will not, constitute a violation of or default under, conflict with, or

                                       4
<PAGE>


result in a breach of any judgment, order, award, decree, of any court,
administrative agency or governmental body or Law.

         3.6 Assets. Premier has and at Closing will convey, good and marketable
title to all of the Assets, free and clear of all claims, liens, security
interests and encumbrances of any nature whatsoever. The Assets include all
assets used to conduct the Division's business as presently conducted. The
machinery, computers and equipment described in Schedule 1.2(b) (ii) will be
conveyed in "AS IS" condition without representation or warranty of any kind
except as to title.

         3.7 Assumed Agreements. Except as indicated on Schedule 3.7, no consent
or other action is necessary in order to assign the Assumed Agreements to the
Company. Except as indicated on said Schedule, each of the Assumed Agreement is
in full force and effect, there is no default or event which with notice or
lapse of time or both would constitute a default under any Assumed Agreement,
all sums owing or to be owing thereunder by Premier with respect to the period
prior to the Closing have been or prior to Closing shall be paid and satisfied
in full, there have been no prepayments by the other party thereto, and, to the
best of Premier's knowledge, there is no obligation of Premier giving rise to
any right of set-off under any Assumed Agreement.

         3.8 Liabilities. Other than trade payables incurred by the Division in
the ordinary course of business after the date of the Balance Sheet, the
Division has no liabilities or obligations (whether accrued, absolute,
contingent or otherwise) of any nature whatsoever which are not reflected on the
Balance Sheet.

         3.9 No Adverse Change. Since June 30, 1995 there has been no material
adverse change in the business, assets, liabilities or financial condition of
the Division, nor has there been any conducting of the Division's business other
than in the ordinary course.

         3.10 Schedules. The following Schedules which are attached hereto
contain accurate lists and summary descriptions of the following:

through its employees, agents and representatives, make or cause to be made such
investigations during normal and reasonable business hours as it deems necessary
or advisable of the properties, assets, businesses, books and records of RDW, to
the extent relevant to this transaction.

         9.9 Right of Offset. The right of Premier to receive payments or
distributions as a member of the Company or otherwise under this Agreement or
the Operating Agreement is subject to any and all defenses of RDW or the Company
based upon, or arising out of, breach of any representation, warranty, covenant
or indemnity obligation for which Premier shall be liable to RDW or the Company,
and RDW or the Company or both may, after giving Premier written notice and a
ten (10) day opportunity to cure, elect to offset against the payment (or, to
the extent necessary, payments) next due hereunder or thereunder amounts for
which Premier is so liable. Acceptance by Premier of any payments so reduced by
offset shall not be deemed an accord, compromise or waiver of rights, including
a waiver of right to dispute the offset, and failure by RDW or the Company to
utilize the offset mechanism shall not be deemed a relinquishment, forgiveness,
waiver, bar or defense in respect of any claim or right (including the
continuing right to offset) of RDW and the Company. In the event of any suit or
other legal proceeding arising out of a contest to an offset under this Section,
the prevailing party shall be entitled to recover from the other party upon a
final judgment on the merits (i) reasonable attorneys' fees, expenses, and costs
incurred in such suit or other legal proceeding and (ii) if Premier is the
prevailing party, interest on the offset as determined by the Court.

Article X, stating the nature and basis of such claim and, if ascertainable, the
amount thereof. In connection with any such third party claim, the indemnifying
party may, at its election and expense, assume the defense of such third party
claim, provided that the indemnifying party shall have acknowledged in writing
its obligation to indemnify in respect of such third party claim. If the
indemnifying party shall not have elected to so assume the defense of such third
party claim, it shall have the right to participate in the defense of such third
party claim and no such third party claim shall be settled without the consent
of the indemnifying party, provided that the indemnifying party shall have

                            TAX ALLOCATION AGREEMENT

                                     BETWEEN

                        UM HOLDINGS Ltd. AND SUBSIDIARIES


TAX ALLOCATION AGREEMENT dated as of December 1, 1994 (this "Agreement"), by and
between UM Holdings Ltd., a New Jersey corporation ("Holdings"), and its
subsidiaries, including, but not limited to Trotter Inc.; Life Extension
Institute, Inc.; Cardio Data Services, Inc.; Research Data Worldwide, Ltd.; UM
Equity Corp; and UM Investments ("Subsidiaries").

WHEREAS, Holdings owns 100% of the voting common stock of Trotter Inc., the only
class of authorized and outstanding stock; 100% of the voting common stock of
Life Extension Institute, Inc., the only class of authorized and outstanding
stock; 100% of the voting common stock of Cardio Data Services, Inc., the only
class of authorized and outstanding stock; 100% of the voting common stock of
Research Data Worldwide, Ltd., the only class of authorized and outstanding
stock 100% of the voting common stock of UM Equity Corp., the only class of
authorized and outstanding stock; 100% of the voting common stock of UM
Investments, the only class of authorized and outstanding stock; and

WHEREAS, Holdings and Subsidiaries desire to file a consolidated federal income
tax return pursuant to section 1501 of the Internal Revenue Code of 1986, as
amended (the "Code"); and

WHEREAS, Holdings and Subsidiaries have filed consolidated federal income tax
returns with its direct and indirect subsidiaries, each of which desires to
become a party to this Agreement (for purposes of this Agreement, references to
"Subsidiaries" shall include each of the Subsidiaries); and

WHEREAS, Holdings and Subsidiaries desire to provide a method for the equitable
apportionment between themselves of the tax consequences of filing consolidated
federal income tax returns and to create a binding obligation on the part of
Subsidiaries to pay to on account of such liability, the amounts specified
herein;

NOW, THEREFORE, intending to be legally bound, Holdings and Subsidiaries hereby
mutually covenant and agree as follows:

1.     Holdings will file a consolidated federal income tax return for the
       affiliated group consisting of itself and Subsidiaries (the "Group") for
       the taxable year ending December 31, 1994, and for any subsequent taxable
       year for which the Group is required or permitted to file such a return
       pursuant to the provisions of the Code and Treasury Regulations
       thereunder.

2.     Subsidiaries hereby irrevocably designates Holdings as its agent for the
       purpose of taking all actions necessary or incidental to the filing of
       consolidated federal income tax returns and dealing with all related tax
       matters. Subsidiaries agrees to file such consents, elections and other
       documents and to take such other actions as may be necessary or
       appropriate to carry out the purpose of this agreement as Holdings may
       request.

<PAGE>


3.     a.     For each taxable year of the Group, Holdings shall pay to the 
              United States Treasury the entire amount of the consolidated 
              federal income tax liability of the Group, at such times as may be
              required or permitted by the Code and Treasury Regulations.

       b.     Each subsidiary shall be responsible for and pay to Holdings those
              amounts which equal the estimated tax payments and final tax 
              payments which such Subsidiary would have made to the United
              States Treasury had its federal income tax liability been computed
              on a separate return basis, determined on the basis of the best 
              information available.  Subsidiaries shall pay such amounts to
              Holdings on the due dates or up to thirty business days subsequent
              to the dates for the estimated and final tax payments to the 
              United States Treasury, which Subsidiaries would have made had it
              been filing on a separate return basis, determined without regard
              to Holdings' obligation to make payments of tax pursuant to 
              paragraph 4.a. hereof.

       c.     In the event that a Subsidiary incurs a loss for federal income
              tax purposes which has the effect of reducing the Group's
              consolidated federal income tax liability for any taxable year,
              Holdings shall not be obligated to pay to such Subsidiary the 
              amount of such reduction. 

       d.     In the event of any adjustment to the consolidated tax returns as
              filed (due to, for instance, the filing of an amended return,
              claim for refund, or an audit by the Internal Revenue Service),
              the liability of Subsidiaries under paragraph 3. b. hereof shall 
              be redetermined to give effect to each such adjustment as if it 
              had been made a part of the original computation of Subsidiaries' 
              tax liability. 

       e.     In applying this paragraph 4, the parties may, for administrative
              convenience and consistent with the purposes of this Agreement,
              consider Subsidiaries' federal income tax liability on a return
              basis to be consolidated federal income tax liability of the
              Subsidiaries.

4.     Nothing in this Agreement shall be construed to prohibit Holdings from
       electing to discontinue filing consolidated federal income tax returns
       for the Group for any taxable year or prohibit Holdings from making or
       forbearing from making any election available to it under the Code.

5.     No modification, amendment or waiver of any provision of this Agreement
       shall be effective unless the same shall be in writing and signed by the
       party against which enforcement of such modification amendment or waiver
       is sought.

6.     All demands, notices and communications hereunder shall be in writing and
       shall be deemed to have been duly given if personally delivered.


<PAGE>

7.     This Agreement shall be binding upon and inure to the benefit of any
       successor, by merger, acquisition of assets or otherwise, to any of the
       parties hereto, to the same extent as if such successor had been an
       original party to this Agreement.

8.     If at any time either Holdings or Subsidiaries acquires or creates one or
       more subsidiary corporations that are eligible to be includible
       corporations of the Group pursuant to the Code and Treasury Regulations
       thereunder, such subsidiary corporations shall be subject to this
       Agreement and all references thereafter to Holdings or Subsidiaries, as
       the case may be, shall be interpreted to include such subsidiary
       corporations.

9.     This Agreement may be executed in any number of counterparts, each of
       which shall be an original, but such counterparts shall together
       constitute but one and the same instrument.

10.    This Agreement shall be construed and enforced in accordance with the 
       laws of the State of New Jersey.

IN WITNESS WHEREOF, the parties have caused this Agreement to be executed by
their respective officers thereunto duly authorized as of the _____ day of 
__________, 1994.

                           For purposes of this Agreement, the term "Clinical
                           Laboratory Business" shall mean the provision of
                           clinical bioanalytical laboratory services used to
                           determine blood and urine test results either placed
                           by a member of the Pharmaco Group or a sponsor
                           (hereinafter referred to as a "Sponsor") in
                           connection with a study being managed by Pharmaco
                           LSR. RDW represents that all such services shall be
                           performed in accordance with Good Laboratory
                           Practices and shall be accorded priority status for
                           scheduling purposes. Clinical Laboratory Business
                           shall be deemed to be placed when Pharmaco, a member
                           of the Pharmaco Group or a Sponsor has entered into a
                           binding agreement with RDW for such services pursuant
                           to which such services will such be completed within
                           six months from the date of the agreement or when the
                           actual services (or portion thereof) are actually
                           performed, whichever is earlier.

                  3.3      RDW shall bill Pharmaco and the Pharmaco Group for
                           all Clinical Laboratory Business performed by RDW
                           pursuant to this Agreement at the rates set forth on
                           Exhibit B attached hereto. The prices set forth on
                           Exhibit B shall remain fixed for the initial twelve
                           month period of this Agreement but thereafter are
                           subject to adjustment from time to time by RDW.
                           During the term of this Agreement, RDW agrees that
                           the maximum permitted increase in any rate set forth
                           on Exhibit B hereto shall be five percent (5%) per
                           calendar year. The Pharmaco Group shall be considered
                           a preferred customer of RDW and at all times the
                           rates charged to the Pharmaco Group shall be at least
                           as favorable as the average rate charged to other
                           similar customers of RDW and at least as favorable as
                           the rates generally available in the market for
                           clients placing work of a similar volume and dollar
                           magnitude. Pharmaco reserves the right to request and
                           receive appropriate documentation from RDW from time
                           to time supporting that its rates conform to the
                           foregoing standard and to audit RDW's books in this
                           respect as it deems appropriate, subject to any
                           applicable confidentiality restrictions imposed by
                           law or contracts with third parties.

                  3.4      RDW shall submit invoices to Pharmaco on a monthly
                           basis for all Clinical Laboratory Business completed
                           by RDW pursuant to this Agreement during the
                           immediately preceding calendar month. Each such
                           invoice shall be due and payable in full within
                           thirty (30) days of the date of the invoice. All
                           amounts not paid within forty-five (45) days after
                           the invoice date shall bear interest, computed
                           monthly, at a rate equal to

                           the lesser of (a) one percent (l%) per month, and (b)
                           the highest rate of interest permitted by applicable
                           law.

                  3.5      The parties have agreed that each of the Annual Fees
                           shall be paid in three equal installments, in
                           arrears, as of the end of the fourth month, the end
                           of the eighth month and the end of the twelfth month
                           of the particular year to which such fee relates
                           (referred to as a "Payment Period"). For instance,
                           the Annual Fee for Year 1 is payable $50,000 on April
                           30, 1995, $50,000 payable on August 31, 1995, and
                           $50,000 payable on December 31, 1995. All amounts not
                           paid within forty-five (45) days after the end of a
                           Payment Period shall bear interest, computed monthly,
                           at a rate equal to the lesser of (a) one percent (1%)
                           per month, and (b) the highest rate of interest
                           permitted by applicable

                           law. Annual Fees may be paid either in cash or
                           through receiving a credit for Clinical Laboratory
                           Business placed with RDW as further described in
                           Section 3.6 below.

                  3.6      The parties have agreed that Pharmaco will receive a
                           credit against the amount it would otherwise owe as
                           an Annual Fee based on a varying percentage of all
                           Clinical Laboratory Business placed by the Pharmaco
                           Group with RDW within any particular Year as follows:

                                                            Credit
                                    Year                    Percentage
                                    ----                    ---------- 
                                    Year 1                    10.00%
                                    Year 2                    8.333%
                                    Year 3                    8.75%
                                    Each year
                                    thereafter                5.00%

                           An invoice shall be prepared by RDW at the end of
                           each Payment Period of this Agreement reflecting (a)
                           the aggregate Clinical Laboratory Business placed by
                           the Pharmaco Group for such period as determined in
                           accordance with Section 3.2 hereof, (b) the amount of
                           credit earned with respect to such business for such
                           period, (c) the amount of any credit carry-forward as
                           determined in accordance with Section 3.7 hereof, (d)
                           the amount of the current credit and then
                           carry-forward credits if any, applied against the
                           installment of the Annual Fee due and owing for such
                           Payment Period, and (e) the balance of the
                           installment of such Annual Fee for such Payment
                           Period, if any, due and owing.

                  3.7      To the extent that the credit received by Pharmaco
                           pursuant to Section 3.6 as calculated for a
                           particular Payment Period exceeds the installment
                           amount of the Annual Fee for such period, the balance
                           or unused portion of such credit will be applied to
                           the next installment amount(s) of the Annual Fee.

                  3.8      In the event that within a particular Year the amount
                           of Clinical Laboratory Business placed with RDW
                           hereunder has resulted in a credit in excess of the
                           amount that can be used to pay the Annual Fee owed
                           for such period, then with respect to any "excess"
                           credit, Pharmaco shall be deemed to have applied such
                           credit to any future Annual Fees on a
                           dollar-for-dollar basis.

                  3.9      It is the intent of the parties that the Pharmaco
                           Group will also attempt to refer Clinical Laboratory
                           Business to RDW's European laboratory facility, once
                           such facility has become operational.

         4.0      Diagnostic Services.

                  4.1      During the term of this Agreement, Pharmaco agrees
                           that RDW shall be the exclusive world-wide provider
                           of all centralized ECG, transtelephonic ECG and
                           Holter monitoring services (collectively, the
                           "Diagnostic Services") contracted for by the Pharmaco
                           Group. This exclusivity requirement shall not be
                           applicable where the trial sponsor has preselected
                           another provider for the Diagnostic Services or where
                           RDW is unable to comply with the protocol or any
                           other of the trial sponsor's requirements applicable
                           to the Diagnostic Services, as reasonably determined
                           by Pharmaco in consultation with RDW. All such
                           Diagnostic Services shall be performed in accordance
                           with Good Laboratory Practices.

                  4.2      RDW shall bill Pharmaco for all Diagnostic Services
                           performed by RDW pursuant to this Agreement at the
                           rates set forth on Exhibit C attached hereto. The
                           prices set forth on Exhibit C are fixed for 1995 and
                           thereafter are subject to adjustment from time to
                           time by RDW. During the term of this Agreement, RDW
                           agrees that the maximum permitted increase in any
                           rate set forth on Exhibit C hereto shall be five
                           percent (5%) per calendar year. Such rates shall be
                           at least as favorable as the average rates charged to
                           other similar customers of RDW and at least as
                           favorable as the rates generally available in the
                           market for clients placing work of a similar volume
                           and dollar magnitude.

                  4.3      RDW shall submit invoices to Pharmaco on a monthly
                           basis for all Diagnostic Services completed by RDW
                           pursuant to this Agreement during the immediately
                           preceding calendar month. Each such invoice shall be
                           due and payable in full within thirty (30) days of
                           the date of the invoice. All amounts not paid within
                           forty-five (45) days after the invoice date shall
                           bear interest, computed monthly, at a rate equal to
                           the lesser of (a) one percent (1%) per month, and (b)
                           the highest rate of interest permitted by applicable
                           law.

         5.0      Further Agreements.

                  5.1      RDW agrees to make available to Pharmaco, at such

                           consultation purposes with respect to the Software.
                           RDW shall bill Pharmaco for the use of such personnel
                           at RDW's then current hourly rates plus all
                           reasonable out-of-pocket expenses incurred. For
                           purposes hereof, out-of-pocket expenses shall be
                           considered "reasonable" only if incurred in
                           accordance with Pharmaco's standard policies, copies
                           of which have been provided to RDW.

                  5.2      RDW also agrees to make available to Pharmaco, at
                           such times and places as shall be mutually agreed

                           Officer, David Evans (or his successor), for
                           consultation purposes with respect to the Software.
                           RDW shall bill Pharmaco for the use of Mr. Evans at a
                           rate equal to his then current hourly billing rate as
                           a member of RDW's senior research and development
                           staff. Notwithstanding anything to the contrary
                           contained herein, the parties agree that nothing
                           contained herein shall be construed as to require Mr.
                           Evans to devote more than twenty-five percent (25%)
                           of his normal working hours to consultation services
                           on behalf of Pharmaco. RDW agrees that any work

                           by Pharmaco in accordance with the terms hereof,
                           shall be considered a work made for hire and shall be
                           the exclusive property of Pharmaco. To the extent any
                           work product produced by Mr. Evans exclusively for
                           Pharmaco pursuant to this Section 5.2 and paid for in

                           to Pharmaco and agrees to take all steps necessary at

                  or to such other address as the party to be notified shall
                  have specified pursuant to this Section 6.0

         7.0      TERMINATION

                  7.1      This Agreement shall commence on the date first set
                           forth above. This Agreement shall continue, unless
                           sooner terminated in accordance with the terms
                           hereof, until the third (3rd) anniversary of the date
                           hereof. Thereafter, this Agreement shall be
                           automatically renewed on an annual basis unless
                           either party elects not to renew, in which event
                           written notice of such election must be given to the
                           other party at least ninety (90) days prior to the
                           end of the then current term. The Annual Fee for any
                           renewal period shall be $100,000 payable in arrears,
                           in three separate installments of $33,333 as of the
                           end of each four month period of the renewal period.
                           During any renewal period Pharmaco will receive a
                           credit against the amount it would otherwise owe as
                           an Annual Fee equal to 5% of the amount of Clinical
                           Laboratory Business placed with RDW as defined in
                           Section 3.2 hereof. No other fees pursuant to Section
                           3 or otherwise shall be due or owing with respect to
                           any renewal period (other than any applicable
                           sublicense fees from sublicensee payable pursuant to
                           Section 2.4 hereof). Unless otherwise agreed to in
                           writing by the parties hereto, all of the terms and
                           conditions of this Agreement shall remain in full

   6. Notice of the Borrowing. The Borrower shall give the Bank either (i)
      written notice of the amount and date of each advance requested under the

      after the oral request by such written Notice of Borrowing Under Revolving
      Credit. An oral request for an advance may be made by (i) any officer of
      the Borrower listed on any borrowing resolution supplied by the Borrower

      authorized, by oral or written notice to the Bank, to act on behalf of the
      Borrower and/or who has been stated in any oral or written confirmation by

      authorized by the Borrower (the "Authorized Representative"). Any advance
      made by the Bank based on a request by anyone purporting to be an
      Authorized Representative shall be binding on the Borrower.
      Notwithstanding the foregoing, the Bank's records of any advance made
      pursuant to this Agreement shall, in the absence of manifest error, be
      deemed correct and acceptable and binding upon the Borrower. Each advance
      shall be in an amount equal to One Thousand and no/100 Dollars ($1,000.00)

      than n/a Business Day(s) prior written notice to the Bank, to terminate

      equal to n/a Dollars ($n/a) or any whole multiple thereof.

      account of the Borrower at the Bank shall be conclusively presumed to have
      been properly authorized by the Borrower. The Bank may, and the Borrower
      authorizes the Bank to, debit the Account or any other account of the
      Borrower at the Bank for the amount of any payment as and when such
      payment becomes due hereunder. If there are insufficient funds in the
      Account at the time the Account is debited, and the debiting creates an
      overdraft, the Bank may charge the Borrower, in addition to any overdraft
      fee, an administrative fee in an amount established from time to time by
      the Bank. The foregoing rights of the Bank to debit the Borrower's
      accounts shall be in addition to, and not in limitation of, any rights of
      set-off which the Bank may have hereunder or under any Loan Document, nor

K. Remedies.

   1. Acceleration of Liabilities; Rights of Bank. Upon and following the
      occurrence of an Event of Default described in Section J hereof (other
      than the Events of Default described in Paragraph J.2.), at the Bank's
      sole option, the Bank's commitment, if any, to make any further advances
      or loans to the Borrower hereunder shall terminate, and all Liabilities
      shall immediately become due and payable in full, all without protest,
      presentment, demand or further notice of any kind to the Borrower or any
      other Obligor, all of which are expressly waived. Upon and occurrence of
      any Event of Default described in Paragraph J.2., immediately and
      automatically, the Bank's commitment, if any, to make any further advances
      or loans to the Borrower hereunder, shall terminate and all Liabilities
      shall immediately become due and payable in full, all without protest,
      presentment, demand or further notice of any kind to the Borrower or any
      other Obligor, all of which are expressly waived. Upon and following an
      Event of Default, the Bank may, at its option, exercise any and all rights
      and remedies it has under this Agreement, the other Loan Documents and
      under applicable law, including, without limitation, the right to charge
      and collect interest on the principal portion of the Liabilities at the
      Default Rate, which rate shall, at the Bank's option, apply upon and after
      an Event of Default arising from failure to pay any amount when due under
      any of the Loan Documents, maturity, whether by acceleration or otherwise,
      and the entry of judgment with respect to any or all of the Liabilities.
      Upon and following an Event of Default hereunder, the Bank may proceed to
      protect and enforce the Bank's rights under any Loan Document and/or under
      applicable law by action at law, in equity, or other appropriate
      proceedings, including, without limitation, an action for specific
      performance to enforce or aid in the enforcement of any provision
      contained herein or in any other Loan Document.

   2. Right of Set-off. If any of the Liabilities shall be due and payable or
      any one or more Events of Default shall have occurred, whether or not the
      Bank shall have made demand under any Loan Document and regardless of the
      adequacy of any Collateral for the Liabilities or other means of obtaining
      repayment of the Liabilities, the Bank shall have the right, without
      notice to the Borrower or any other Obligor, and is specifically
      authorized hereby to set-off against and apply to the then unpaid balance
      of the Liabilities any items or funds of the Borrower and/or any Obligor
      held by the Bank or any Affiliate, any and all deposits (whether general
      or special, time or demand, matured or unmatured) or any other property of
      the Borrower and/or any Obligor, including, without limitation, securities
      and/or certificates of deposit, now or hereafter maintained by the
      Borrower and/or any Obligor for its or their own account with the Bank or
      any Affiliate, and any other indebtedness at any time held or owing by
      the Bank or any Affiliate to or for the credit or the account of the
      Borrower and/or any Obligor, even if effecting such set-off results in a
      loss or reduction of interest or the imposition of a penalty applicable to
      the early withdrawal of time deposits. For such purpose, the Bank shall
      have, and the Borrower hereby grants to the Bank, a first lien on and 
      security interest in such deposits, property, funds, and accounts, and the
      proceeds thereof. The Borrower further authorizes any Affiliate, upon and
      following the occurrence of an Event of Default, at the request of the
      Bank, and without notice to the Borrower, to turn over to the Bank any
      property of the Borrower, including, without limitation, funds and
      securities, held by the Affiliate for the Borrower's account and to debit,
      for the benefit of the Bank, any deposit account maintained by the
      Borrower with such Affiliate (even if such deposit account is not then due
      or there results a loss or reduction of interest or the imposition of a
      penalty in accordance with law applicable to the early withdrawal of time
      deposits), in the amount requested by the Bank up to the amount of the
      Liabilities, and to pay or transfer such amount or property to the Bank
      for application to the Liabilities.

   3. Confession of Judgment.

      a. THE FOLLOWING PARAGRAPH SETS FORTH A WARRANT OF AUTHORITY FOR ANY
         ATTORNEY TO CONFESS JUDGMENT AGAINST THE BORROWER. IN GRANTING THIS
         WARRANT OF ATTORNEY TO CONFESS JUDGMENT AGAINST THE BORROWER, THE
         BORROWER, FOLLOWING CONSULTATION WITH (OR DECISION NOT TO CONSULT)
         SEPARATE COUNSEL FOR THE BORROWER AND WITH KNOWLEDGE OF THE LEGAL
         EFFECT HEREOF, HEREBY KNOWINGLY, INTENTIONALLY, VOLUNTARILY AND
         UNCONDITIONALLY WAIVES ANY AND ALL RIGHTS THE BORROWER HAS OR MAY HAVE
         TO PRIOR NOTICE AND AN OPPORTUNITY FOR HEARING UNDER THE RESPECTIVE
         CONSTITUTIONS AND LAWS OF THE UNITED STATES OF AMERICA, THE
         COMMONWEALTH OF PENNSYLVANIA, OR ELSEWHERE. IT IS SPECIFICALLY
         ACKNOWLEDGED BY THE BORROWER THAT THE BANK HAS RELIED ON THIS WARRANT
         OF ATTORNEY IN RECEIVING THIS AGREEMENT AND AS AN INDUCEMENT TO GRANT
         FINANCIAL ACCOMMODATION CONTAINED HEREIN.

      b. Upon and following the occurrence of an Event of Default, the Borrower
         hereby jointly and severally authorizes and empowers any attorney of
         any court of record or the prothonotary or clerk of any county in
         Commonwealth of Pennsylvania, or in any jurisdiction where permitted by
         law or the clerk of any United States District Court, to appear for the
         Borrower or any of them in any and all actions which may be brought
         hereunder and enter and confess judgement against the Borrower or any
         of them in favor of the Bank for such sums as are due or may become due
         hereunder or under any other Loan Document, together with costs of suit
         and actual collection costs including, without limitation, reasonable
         attorneys' fees equal to five percent (5%) of the Liabilities then due
         and owing but in no event less than $5,000, with or without
         declaration, without prior notice, without stay of execution and with
         release of all procedural errors and the right to issue executions
         forthwith. To the extent permitted by law, the Borrower waives the
         right of inquisition on any real estate levied on, voluntarily condemns
         the same, authorizes the prothonotary or clerk to enter upon the writ
         of execution this voluntary condemnation and agrees that such real
         estate may be sold on a writ of execution; and also waives any relief
         from any appraisement, stay or exemption law of any state now in force
         or hereafter enacted. If a copy of this Agreement verified by affidavit
         of any officer of the Bank shall have been filed in such action, it
         shall not be necessary to file the original thereof as a warrant of
         attorney, any practice or usage to the contrary notwithstanding. The
         authority herein granted to confess judgement shall not be exhausted by
         any single exercise thereof, but shall continue and may be exercised
         from time to time as often as the Bank shall find it necessary and
         desirable and at all time until full payment of all amounts due
         hereunder and under the other Loan Documents. The Bank may confess one
         or more judgments in the same or different jurisdictions for all or any
         part of the obligations arising hereunder or under any other Loan
         Document, without regard to whether judgment has theretofore been
         confessed on more than one occasion for the same obligations. In the
         event that any judgment confessed against the Borrower is stricken or
         opened upon application by or on behalf of the Borrower or any Obligor
         for any reason, the Bank is hereby authorized and empowered to again
         appear for and confess judgment against the Borrower for any part or
         all of the obligations due and owing under this Note, as herein
         provided.

   4. Remedies Cumulative; No Waiver. The rights, powers and remedies of the
      Bank provided in this Agreement and any of the Loan Documents are
      cumulative and not exclusive of any right, power or remedy provided by law
      or equity. No failure or delay on the part of the Bank in the exercise of
      any right, power or remedy shall operate as a waiver thereof, nor shall
      any single or partial exercise preclude any other or further exercise
      thereof, or the exercise of any other right, power or remedy.

   5. Continuing Enforcement of the Loan Documents. If, after receipt of any
      payment of all or any part of the Liabilities, the Bank is compelled or
      agrees, for settlement purposes, to surrender such payment to any person
      or entity for any reason, then this Agreement and the other Loan Documents
      shall continue in full force and effect or be reinstated, as the case may
      be. The provisions of this Paragraph shall survive the termination of this
      Agreement and the other Loan Documents and shall be and remain effective
      notwithstanding the payment of the Liabilities, the cancellation of the
      Agreement, the release of any security interest, lien or encumbrance

   8. Severability and Consistency. The illegality, unenforceability or
      inconsistency of any provision of this Agreement or any instrument or
      agreement required hereunder shall not in any way affect or impair the
      legality, enforceability or consistency of the remaining provisions of
      this Agreement or any instrument or agreement required hereunder. The Loan
      Documents are intended to be consistent. However, in the event of any
      inconsistencies among any of the Loan Documents, such inconsistency shall

      process or pleading in any action or proceeding against it arising out of

           SCHEDULE OF ADDITIONAL TERMS TO REVOLVING CREDIT AGREEMENT
                AND REVOLVING CREDIT NOTE, DATED JUNE 13, 1996,
                    BY AND BETWEEN THE BANK AND THE BORROWER
                    ----------------------------------------

A. Paragraph A.2. of the Agreement and Paragraph A.6. of the Note are hereby
each deleted in their entirety and the following provision is substituted in
each of their places:

   Maximum Principal Amount. The maximum aggregate principal amount of advances
   to be outstanding at any time hereunder (the "Maximum Principal Amount") is
   the lesser of: (i) One Million Dollars ($1,000,000); or (ii) 60% of
   Borrower's Eligible Accounts. The Borrower shall not request the Bank to make
   any advances under the Note which, when added to the principal balance
   outstanding under the Note, would cause the principal balance outstanding
   under the Note to exceed the Maximum Principal Amount. In the event that the
   principal balance outstanding under the Note exceeds at any time the Maximum
   Principal Amount, the Borrower shall immediately, and without demand from the
   Bank, pay to the Bank the amount in excess of the Maximum Principal Amount
   (the "Excess") and the Borrower agrees that until such Excess is paid to the
   Bank, this Note shall evidence and be enforceable with respect to any and all
   amounts outstanding hereunder including such Excess.

B. The following definition is hereby added in alphabetical order to Section C.
of the Agreement:

   Eligible Account. The term "Eligible Account" means each account which meets
   all of the following criteria: (a) the account arose from a bona fide
   outright sale of goods by the Borrower, or for services performed by the
   Borrower, under an enforceable contract, within the United States for an
   individual or entity located within the United States (other than the United
   States Government or any state governmental body, unless the Borrower has
   complied to the Bank's satisfaction with the Federal Assignment of Claims Act
   or any comparable state statute) and such goods have been shipped to the
   appropriate account debtor, or the sale has otherwise been consummated, or
   the services have been performed for the appropriate account debtor in
   accordance with such contract; (b) the title of the Borrower to the account
   is absolute and is not subject to any prior assignment or encumbrance; (c)
   the amount of the account shown on the books of the Borrower and on any
   invoice or statement delivered to the Bank is owing to the Borrower and no
   partial payment has been made thereon by any individual or entity, other than
   non-refundable customer deposits; (d) the account is not a contra account and
   is not subject to any claim of reduction, counterclaim, set-off, recoupment,
   or any claim for credits, allowances or adjustments by the account debtor
   because of returned, inferior or damaged goods or unsatisfactory services, or
   for any other reason, except for customary discounts allowed for prompt
   payment; (e) not more than fifty percent (50%) of the aggregate accounts due
   from the account debtor remain unpaid for more than one hundred and twenty
   (120) days past the invoice date; (f) the account debtor has not returned or
   refused to accept or retain any of the goods or services from the sale or
   furnishing of which the account arose; (g) the age of the account, calculated
   from the date of the invoice therefor, is not more than ninety (90) days; (h)
   the account debtor is not an employee, stockholder, affiliate or subsidiary
   of the Borrower; (i) an invoice reflecting the account has been issued by the
   Borrower to the account debtor, and neither the invoice nor the account
   reflected on the Borrower's books has been redated; and (j) the account is
   not an account that the Bank, in its sole discretion, has determined does not
   constitute an Eligible Account in whole or in part, whether because the
   account debtor does not meet the Bank's credit standards or otherwise.

                                       1
<PAGE>

C. The following representation and warranty is hereby added in numerical order
to Section E. of the Agreement:

   Eligible Accounts and Borrowing Base Certificates. All accounts reported to
   the Bank as Eligible Accounts in the quarterly borrowing base certificates
   submitted by the Borrower or relied on by the Borrower in requesting an
   advance under the Revolver meet all of the criteria set forth in the
   definition of Eligible Account set forth herein, and the most recent
   borrowing base certificate submitted by the Borrower to the Bank was true and
   correct in all respects on the date submitted and the Borrower is not aware
   of any facts or circumstances that would make such borrowing base certificate
   untrue or incorrect in any respect as of the date on which it was made.

D. Paragraph G.1. of the Agreement is hereby deleted in its entirety and the
following provision is substituted in its place:

   1. Financial Statements. Furnish to the Bank the following financial
      information: (i) not later than one hundred and twenty (120) days after
      the end of each fiscal year, consolidated and consolidating audited

      consolidated subsidiaries, including, but not limited to, statements of
      financial condition, income and cash flows, a reconciliation of net worth,
      notes to financial statements (all of the above prepared in accordance
      with GAAP, consistently applied, by an independent certified public
      accountant acceptable to the Bank, and certified as true, correct, and
      complete by the Borrower's chief financial officer), and any other
      information that may assist the Bank in assessing the Borrower's financial
      condition; (ii) not later than thirty (30) days after the end of each
      interim fiscal quarter, the Borrower's consolidated and divisional
      financial statements, including, but not limited to, statements of
      financial condition, income and cash flows, and a reconciliation of net
      worth (all of the above prepared in a format acceptable to the Bank,
      certified as true, correct, and complete by the Borrower's chief financial
      officer); (iii) the following statements and schedules relating to the
      Borrower's business, not later than thirty (30) days identifying both
      billed and unbilled amounts, (b) a borrowing base certificate presenting
      eligible accounts receivable relative to outstanding advances under the
      Revolver, and (c) monthly management reports, including backlog and
      pipeline information, for the prior three months, as presented to the
      Borrower's Board of Directors, and/or (iv) such information respecting the
      operations, financial or otherwise, of the Borrower or any of its
      subsidiaries, as the Bank may from time to time reasonably request;

$1,000,000.00

FOR VALUE RECEIVED, and intending to be legally bound hereby, the Borrower,
jointly and severally and unconditionally promise(s) to pay to the order of
First Union National Bank, (the "Bank"), the principal amount of all advances
that are now or may hereafter be made hereunder and that are then outstanding,
together with accrued, unpaid interest thereof and any unpaid costs and expenses
payable hereunder, on June 30, 1997.

A. Terms of Note.

   1. Interest Payments. The principal amounts outstanding under this Revolving
      Credit Note (together with any attachments hereto and any amendments and
      modifications hereto in effect from time to time, the "Note") shall bear
      interest at the Bank's Prime Rate plus one-half of one percent (0.500%).
      Accrued interest shall be due and payable by the Borrower to the Bank
      monthly commencing on July 1, 1996, and on the same day of each such
      consecutive period thereafter, and upon payment in full of the outstanding
      principal balance hereof.

   2. Computation of Interest. Interest charged hereunder shall be computed
      daily on the basis of a 360 day year for the actual number of days
      elapsed. All payments hereunder shall be made in lawful currency of the
      United States of America and in immediately available funds. All payments
      made hereunder shall be made to the Bank at its offices set forth in this
      Note or at such other address as the Bank shall notify the Borrower of in
      writing.

   3. Incorporation by Reference. This Note is the note referred to in that
      certain Revolving Credit Agreement dated June 13, 1996, between the Bank
      and the Borrower (together with any exhibits thereto and amendments and
      modifications thereto in effect from time to time, the "Loan Agreement")
      and is subject to the terms and conditions thereof, which terms and
      conditions are incorporated herein, including, without limitation, terms
      pertaining to definitions, representations, warranties, covenants, events
      of default and remedies. Any capitalized term used herein without
      definition shall have the definition contained in the Loan Agreement.

   4. Borrowing Requests; Crediting of Account. Any request for borrowing
      pursuant to this Note shall be made by the Borrower in writing one (1)
      Business Days prior to the date of such proposed advance in the form of a
      "Notice of Borrowing under Revolving Credit" attached hereto as Exhibit
      "A" or in accordance with the terms of the Loan Agreement. Notwithstanding
      the foregoing, the Bank's records of any advance made pursuant to this
      Note shall, in the absence of manifest error, be deemed correct and
      acceptable and binding upon the Borrower. Each advance hereunder shall be
      made by crediting the Account (hereinafter defined) with the amount of the
      advance. All advances made by crediting the Account or any other account
      of the Borrower at the Bank shall be conclusively presumed to have been
      properly authorized by the Borrower.

<PAGE>


   5. Bank Records of Advance. The Bank may enter in its business records the
      date and the amount of each advance made pursuant to this Note and the
      Loan Agreement. The Bank's records of such advance shall, in the absence
      of manifest error, be conclusively binding upon the Borrower. In the event
      the Bank gives notice or renders a statement by mailing or telecopying
      such notice or statement to the Borrower, concerning any such advance or
      the amount of principal and interest due on this Note, the Borrower agrees
      that, unless the Bank receives a written notification of exceptions to
      this statement within ten (10) calendar days after such statement or
      notice is mailed or telecopied, the statement or notice shall be an
      account stated, correct and acceptable and binding upon the Borrower.

   6. Advance Requests Exceeding Maximum Principal Amount. The Borrower shall
      not request the Bank to make any advances under this Note or the Loan
      Agreement which, when added to the principal balance outstanding
      hereunder, would cause the principal balance outstanding hereunder to
      exceed One Million and 00/100 Dollars ($1,000,000.00) (the "Maximum
      Principal Amount"). In the event that the principal balance outstanding
      under this Note exceeds at any time the Maximum Principal Amount, the
      Borrower shall immediately, and without demand from the Bank, pay to the
      Bank the amount in excess of the Maximum Principal Amount (the "Excess")
      and the Borrower agrees that until such Excess is paid to the Bank, this
      Note shall evidence and be enforceable with respect to any and all amounts
      outstanding hereunder including such Excess.

   7. Debting of Account. The Borrower agrees to maintain an account (the
      "Account") at the Bank continuously until the Liabilities due hereunder
      are paid in full. All advances made by crediting the Account or any other
      account of the Borrower at the Bank shall be conclusively presumed to have
      been properly authorized by the Borrower. The Bank may, and the Borrower
      authorizes the Bank to, debit the Account or any other account of the
      Borrower at the Bank for the amount of any payment as and when such
      payment becomes due hereunder. If there are insufficient funds in the
      Account at the time the Account is debited, and the debiting creates an
      overdraft, the Bank may charge the Borrower, in addition to any overdraft
      fee, an administrative fee in an amount established from time to time by
      the Bank. The foregoing rights of the Bank to debit the Borrower's
      accounts shall be in addition to, and not in limitation of, any rights of
      set-off which the Bank may have hereunder or under any Loan Document, nor
      shall the rights hereunder limit the Bank's recourse to any particular
      source of funds or monies.

   8. Application of Payments. All payments received on this Note shall be
      applied first to the Bank's fees, costs and expenses which the Borrower is
      obligated to pay pursuant to the terms hereof and under any other Loan
      Document, then to accrued and unpaid interest and then to principal.

   9. Late Charge. If any payment hereunder is not paid in full when the same is
      due, at the Bank's option exercisable at the time of any late payment, the
      Bank may collect from the Borrower a fee on such unpaid amount equal to
      five percent (5%) of such amount.

  10. Default Rate. At the Bank's option, interest will be assessed on any
      principal which remains unpaid at the maturity of this Note, whether by
      acceleration or otherwise, or upon the occurrence of an Event of Default
      arising from failure to pay any amount when due under any of the Loan
      Documents, at a rate which is four percent (4%) higher than the rate
      otherwise charged hereunder (the "Default Rate") provided that at no time
      shall the Default Rate exceed the highest rate of interest allowed by law.
      Such Default Rate of interest shall also be charged on the amount owed by
      the Borrower to the Bank pursuant to any judgment entered in favor of the
      Bank with respect to this Note or any other Loan Document.

  11. Prepayment. Prepayment of principal may be made at any time without
      prepayment penalty or premium. All payments received on this Note may be
      applied in such order as the Bank in its sole discretion shall determine.

Security. The Bank is hereby granted a continuing security interest in the
Collateral as security for the payment of this Note and any other Liabilities,
which security interest shall be enforceable and subject to all the provisions
of this Note. Upon and following an Event of Default hereunder, the Collateral
may be applied by the Bank at any time to the Liabilities in any order deemed
appropriate by the Bank, in its sole and absolute discretion, without notice to
the Borrower.

Confession of Judgment.

1. THE FOLLOWING PARAGRAPH SETS FORTH A WARRANT OF AUTHORITY FOR ANY ATTORNEY TO
   CONFESS JUDGMENT AGAINST THE BORROWER. IN GRANTING THIS WARRANT OF ATTORNEY
   TO CONFESS JUDGMENT AGAINST THE BORROWER, THE BORROWER, FOLLOWING
   CONSULTATION WITH (OR DECISION NOT TO CONSULT) SEPARATE COUNSEL FOR THE
   BORROWER AND WITH KNOWLEDGE OF THE LEGAL EFFECT HEREOF, HEREBY KNOWINGLY,
   INTENTIONALLY, VOLUNTARILY AND UNCONDITIONALLY WAIVES ANY AND ALL RIGHTS THE
   BORROWER HAS OR MAY HAVE TO PRIOR NOTICE AND AN OPPORTUNITY FOR HEARING UNDER
   THE RESPECTIVE CONSTITUTIONS AND LAWS OF THE UNITED STATES OF AMERICA, THE
   COMMONWEALTH OF PENNSYLVANIA, OR ELSEWHERE. IT IS SPECIFICALLY ACKNOWLEDGED
   BY THE BORROWER THAT THE BANK HAS RELIED ON THIS WARRANT OF ATTORNEY IN
   RECEIVING THIS NOTE AND AS AN INDUCEMENT TO GRANT FINANCIAL ACCOMMODATIONS TO
   THE BORROWER.

2. Upon and following the occurrence of an Event of Default, the Borrower hereby
   jointly and severally authorizes and empowers any attorney of any court of
   record or the prothonotary or clerk of any county in the Commonwealth of
   Pennsylvania, or in any jurisdiction where permitted by law or the clerk of
   any United States District Court, to appear for the Borrower in any and all
   actions which may be brought hereunder and enter and confess judgment against
   the Borrower or any of them in favor of the Bank for such sums as are due or
   may become due hereunder or under any other Loan Document, together with
   costs of suit and actual collection costs including, without limitation,
   reasonable attorneys' fees equal to five percent (5%) of the Liabilities then
   due and owing but in no event less than $5000, with or without declaration,
   without prior notice, without stay of execution and with release of all
   procedural errors and the right to issue executions forthwith. To the extent
   permitted by law, the Borrower waives the right of inquisition on any real
   estate levied on, voluntarily condemns the same, authorizes the prothonotary
   or clerk to enter upon the writ of execution this voluntary condemnation and
   agrees that such real estate may be sold on a writ of execution; and also
   waives any relief from any appraisement, stay or exemption law of any state
   now in force or hereafter enacted. If a copy of this Note verified by
   affidavit of any officer of the Bank shall have been filed in such action, it
   shall not be necessary to file the original thereof as a warrant of attorney,
   any practice or usage to the contrary notwithstanding. The authority herein
   granted to confess judgment shall not be exhausted by any single exercise
   thereof but shall continue and may be exercised from time to time as often as
   the Bank shall find it necessary and desirable and at all times until full
   payment of all amounts due hereunder and under the other Loan Documents. The
   Bank may confess one or more judgments in the same or different jurisdictions
   for all or any part of the Borrower's obligations arising hereunder or under
   any other Loan Document to which the Borrower is a party, without regard to
   whether judgment has theretofore been confessed on more than one occasion for
   the same obligations. In the event that any judgment confessed against the
   Borrower is stricken or opened upon application by or on behalf of the
   Borrower or any Obligor for any reason, the Bank is hereby authorized and
   empowered to again appear for and confess judgment against the Borrower for
   any part or all of the obligations due and owing under this Note, as herein
   provided.

IN WITNESS WHEREOF, the Borrower, intending to be legally bound hereby, has
executed and delivered to the Bank this Note, as of the day and year first above
written.
