                                 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 
85 clients, including 22 of the 25 largest pharmaceutical companies in the 
world (on the basis of 1995 research and development expeditures as reported 
by Med Ad News). In the first nine months of 1996, the Company performed 
services under 168 contracts for 57 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. 

   The Company and its predecessors have operated since 1977 as direct or 
indirect subsidiaries or as divisions of UM Holdings, Ltd., a private holding 
company that owns several companies in different industries. 
    
   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 with PREMIER, Inc. a limited liability company, 
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 in accordance with an agreement entered 
into by the parties in 1995. Upon such conversion, the limited liability 
company will be wholly-owned by 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 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, biotechnology and medical 
device 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; 
clients' decisions to downsize their product development portfolios; 
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 82.4% 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."

<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. 
   
SIGNIFICANT UNALLOCATED NET PROCEEDS 

   The Company intends to use $6 million to $8 million of the net proceeds of 
this offering for capital expenditures and $2 million to $4 million for 
geographic expansion. The Company intends to use the remaining net proceeds 
for possible future acquisitions, working capital and other general corporate 
purposes. The Company has no commitments or agreements with respect to any 
acquisition. The Company has no other specific uses for the proceeds of this 
offering, and the exact uses of such proceeds will be subject to the 
discretion of management. See "Use of Proceeds." 
    
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 

                                      8 
<PAGE>

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 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. While the Company is not aware of any errors or 
omissions which are likely to have a material adverse impact on its financial 
condition, 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 

                                      9 
<PAGE>

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. 
   
   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 or 
cost containment pressures 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 

                                      10 
<PAGE>

   
certain specified conditions. The Certificate of Incorporation also provides 
for staggered three year terms for members of the Board of Directors, the 
amendment of which requires an affirmative super-majority (70%) stockholder 
vote. 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 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 of $10.59 per share. 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 private holding company that owns several companies in different
industries, including a manufacturer and distributor of fitness equipment, a
provider of management services to providers of executive physical examinations
and other medical services, and a regional commercial airline. 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 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 the Company 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, pursuant to an agreement entered into by the parties in 1995. 
After such conversion, the limited liability company will be wholly-owned by 
the Company. Shortly after forming the limited liability company, the Company 
changed its name from Research Data Worldwide, Ltd. 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 $6 million to $8 million of the net proceeds of 
this offering for capital expenditures (including expansion of facilities, 
acquisition of equipment and development and improvement of information 
technology systems), and $2 million to $4 million to fund the costs of 
geographic expansion involving new offices in California and North Carolina 
and expansion of the Company's office in the United Kingdom. The remainder of 
the net proceeds will be used for working capital and other general 
corporate purposes, including possible future acquisitions. 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
additional distributions of $450,000 paid 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 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:

   The following table summarizes on a pro forma as adjusted basis as of 
September 30,1996, the differences between the existing stockholders and new 
investors purchasing shares in this offering (at an assumed initial public 
offering price of $15.00 per share) with respect to the number of shares of 
Common Stock purchased from the Company, the total consideration paid and the 
average price per share paid to the Company:

(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) The sale 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 generally 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 nine months ended September 30, 1996, 16 Company 
contracts were terminated for which the remaining contract amounts totalled 
approximately $3.0 million. Although 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, 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. 
    
   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. 
   
   In the last year, 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 because backlog can be affected by a number of 
factors, including variable size and duration of contracts, some of which are 
performed over several years. The Company recognizes revenue over the 
duration of the contract as services are provided. 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. 

                                      17 
<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.

<PAGE>

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 and a reduced pressure to 
file CANDAs stemming from a reduction in FDA review time. 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. The Company 
believes that these factors are unlikely to cause a continuing decrease in 
CANDA and Phase I revenues, but that these business areas are likely to 
experience slower growth than other sectors of its business. 
    
   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 discontinued such variable fees effective January 1, 1997. See "Certain
Relationships and Related Party Transactions" 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 

                                      18
<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.

<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 from 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 primarily the result of the timing of cash collections and a $1.3 million 
increase in revenues for the quarter ended September 30, 1996 compared to the 
quarter ended September 30, 1995, and 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. For 
the year ended December 31, 1994, the Company's operations generated $1.6 
million in cash, primarily attributable to the Company's net income and 
depreciation of $1.2 million. During 1994, the Company acquired property and 
equipment for $0.8 million. At December 31, 1994, the Company had cash and 
cash equivalents of $0.4 million and working capital of $0.1 million. For the 
year ended December 31, 1993, the Company's operations generated $1.5 million 
in cash, primarily attributable to depreciation of $0.8 million and $0.5 
million increase in deferred revenues for up-front contract payments. During 
1993, the Company acquired property and equipment for $2.0 million. 
    

                                      21

   The Company has a $1.0 million Revolving Credit Facility with First Union 
National Bank 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, including distributions of $450,000 paid 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." 

   The Company believes that the effects of inflation and changing prices 
generally do not have a material adverse effect on its results of operations 
or financial condition.

                                   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 
85 clients, including 22 of the 25 largest pharmaceutical companies in the 
world (on the basis of research and development expenditures as reported by 
Med Ad News). In the first nine months of 1996, the Company performed 
services under 168 contracts for 57 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 with PREMIER, Inc. a limited liability company, 
which is owned 65% by the Company and 35% by PREMIER, Inc. 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. 

                                      23 
<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 
   
   According to R&D Directions magazine, 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 

                                      24
<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. According to the Pharmaceutical Research and 
Manufacturers of America, from 1989 to 1996, the number of biotechnology 
products in clinical trials rose from 80 to over 280, an annual compounded 
growth rate of approximately 20%. 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 are 
described below. While the Company does not believe it practicable to 
quantify or otherwise attempt to assign relative weights to the specific 
strategies, the following strategies are listed in what the Company believes 
to be their general order of importance. 
    
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 

                                      25
<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. As part of this 
expansion strategy, the Company intends to hire additional personnel in the 
clinical trial management and clinical data management areas for its 
Peterborough, UK office, and during 1997 it intends to increasingly use the 
UK office to support international elements of U.S. trials. 
    
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. While the Company is actively 
seeking such strategic acquisitions, it has no commitments or agreements with 
respect to any acquisition. 
    
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 with PREMIER, Inc. 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 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: 

                                      26
<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. 

                                      27
<PAGE>

   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 PremierResearchoFax system, a 
data entry system based on a combination of a commercially available 
technology (DataFax(TR), Clinical DataFax Systems Inc.) and procedures and 
software developed by the Company, which can accelerate the completion, 
correction and review of accurate CRF data. The PremierResearcho Fax system 
permits a CRF to be filled out by the investigating site, faxed to the 
Company and reviewed using the Company's Navigator system 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 
PremierResearchoCARD (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- 

                                      28
<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). 

                                      29 
<PAGE>

   The Company's technology includes: 
   
   PremierResearchoNavigator. 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 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. 

   PremierResearchoEnterprise. 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. 
   
   PremierResearchoFax. The Company has developed an overall data-handling 
process based on the use of a commercial technology (DataFax(TR), Clinical 
DataFax Systems Inc.) supplemented by validation procedures and export 
software and procedures allowing integration into the Company's proprietary 
Navigator system in an overall system referred to as the PremierResearcho Fax 
process. 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 into 
the Navigator system for clinical review. 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. Pursuant to an agreement between the parties, 
PREMIER, Inc. contributed to the limited liability company cash in the amount 
of $300,000, certain other assets and certain contracts, and the Company 
agreed to manage the limited liability company and to fund its working 
capital requirements for a three year period. Upon the closing of this 
offering, PREMIER, Inc.'s interest in the limited liability company will, 
pursuant to the 1995 agreement, convert into 330,150 shares of the Company's 
Common Stock. After such conversion, the limited liability company will be
wholly-owned by the Company.
    
   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 

                                      31 
<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 22 of the 
top 25 pharmaceutical companies in the world as ranked by 1995 research and 
development expenditures as reported by Med Ad News. 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 168 contracts 
to 57 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 Company believes that it is in material compliance with all 
applicable governmental regulations. 
    
   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- 

                                      33
<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 institutional review board ("IRB") at 
each institution at which the trial is conducted. The IRB reviews the study 
to verify the method of experimentation and safety, and to 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. 

                                      34 
<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 

                                      35
<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. 

                                      36 
<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 in 
the aggregate and an umbrella policy of $3 million. 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. 

LEGAL PROCEEDINGS 

   The Company is involved in legal proceedings from time to time in the 
ordinary course of its business. Management believes that none of these legal 
proceedings will have a material adverse effect on the financial condition or 
results of operations of the Company

(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 43 
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. 

                                       42
<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. 

                                      43 
<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 AND RELATED PARTY TRANSACTIONS 
    
   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, for these services. 

   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. 

   The Company believes that the terms of all of the above transactions are 
as favorable to the Company as would have been obtained through arms-length 
negotiations with an unrelated party.

                         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, and an affirmative super-majority (70%) 
stockholder vote to amend the provision of the Certificate of Incorporation 
pertaining to a staggered Board of Directors. 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 

                                      46 
<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. 

TRANSFER AGENT 
   
   The transfer agent and registrar for the Common Stock is First Union 
National Bank. 
    
                       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.

                                 UNDERWRITING 

   The Underwriters named below, represented by Montgomery Securities, Furman 
Selz LLC and Genesis Merchant Group Securities (the "Representatives"), have 
severally agreed, subject to the terms and conditions set forth in the 
Underwriting Agreement, to purchase from the Company and the Selling 
Stockholder the number of shares of Common Stock indicated below opposite 
their respective names at the initial public offering price less the 
underwriting discount set forth on the cover page of this Prospectus. The 
Underwriting Agreement provides that the obligations of the Underwriters are 
subject to certain conditions precedent, and that the Underwriters are

                                                                   Number of

   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 shares of 
Common Stock are first offered for sale pursuant to 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, the Selling 
Stockholder and UM Holdings, Ltd. 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 offering of shares pursuant to 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. A provision for the loss on a contract is made when current estimates 
indicate a total contract loss. 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 BALANCE SHEET 

   The Company's pro forma balance sheet reflects the distributions of 
$450,000 to be paid to UM in the fourth quarter of 1996. 
    
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:

<PAGE>
   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). 

9. COMMITMENTS AND CONTINGENCIES: 

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. 

10. GEOGRAPHIC INFORMATION:

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.

         The following is an estimate of the expenses to be incurred in

- --------------
         *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 January 1996, the Company's principal stockholder, UM Holdings,
Ltd., sold to Joel Morganroth, M.D., the Company's President and Chief Executive
Officer, 300 shares of Common Stock for a purchase price of $750,000 which was
satisfied by the delivery of Dr. Morganroth's promissory note in such amount.
There were no underwriting discounts or commissions paid in connection with this
transaction. UM Holdings, Ltd. relied upon the availability of Section 4(2) of
the Securities Act of 1933, as amended, in that the sale did not involve a
public offering.

         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.

         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.

Premier Research Worldwide, Ltd.
124 S. 15th Street
Philadelphia, Pennsylvania  19102-3010

Attn:  Joel Morganroth, M.D., President

Dear Sirs:

      We have examined the corporate records and proceedings of Premier Research
Worldwide, Ltd., a Delaware corporation (the "Company"), with respect to the
legal sufficiency of all corporate proceedings of the Company taken in
connection with the creation, form, validity, full payment and non-assessability
when issued of the 2,750,000 shares of Common Stock, par value $.01 per share
(the "Common Stock") covered by the Registration Statement on Form S-1, File No.
333-17001 (the "Registration Statement"), in connection with which Registration
Statement this opinion is rendered.

      Based upon such examination, we are of the opinion that when the
Registration Statement shall have been declared effective by order of the United
States Securities and Exchange Commission, and the Common Stock shall have been
issued and sold upon the terms and conditions set forth in the Registration
Statement, such Common Stock will be validly authorized and legally issued,
fully paid and non-assessable.

      We hereby consent (1) to be named in the Registration Statement, and in
the Prospectus which constitutes a part thereof, as the attorneys who will pass
upon legal matters in connection with the sale of the Common Stock, and (2) the
filing of this opinion as Exhibit 5.1 to the Registration Statement.

                                                     Very truly yours,

                                                     /s/ James H. Carll

                                                     JAMES H. CARLL

                                OPTION AGREEMENT

                        PREMIER RESEARCH WORLDWIDE, LTD.


         Dated as of April 23, 1996 and restated as of November 30, 1996, and
delivered by Premier Research Worldwide, Ltd., a Delaware corporation (the
"Company"), to PREMIER, Inc (the "Optionee"), on behalf of Connie Woodburn
("Woodburn"), an officer of Optionee and a member of the Board of Directors of
the Company.

         1. Grant. Subject to the terms and provisions hereinafter set forth,
the Company hereby confirms the grant to the Optionee of an option (the
"Option") to purchase an aggregate of 4,402 shares of the common stock, $.01 par
value (the "Common Stock"), of the Company, subject to adjustment as provided
herein, at a price determined in the manner set forth herein. The option
exercise price will equal the Price to the Public of a share of the Common Stock
in the IPO (as defined herein), unless the IPO does not occur prior to December
31, 1997, in which case the option price shall equal the fair market value of
the Common Stock on the date of grant of this Option (April 23, 1996), as
reasonably determined by the Board of Directors.

         2. Expiration of Option. The Option shall expire on April 23, 2003,
unless earlier terminated as follows:

            (a) Termination of Directorship. If Woodburn shall cease to be a
member of the Board of Directors of the Company for any reason, the Option shall
terminate three months following such event.

<PAGE>




            (b) IPO. The Option shall terminate at the end of the five year
period following the closing of the first sale by the Company of shares of its
Common Stock in a registered public offering (an "IPO").

            (c) Sale. The Option shall terminate one month following a Sale of
the Company. For purposes herein, the term "Sale" refers to any sale of
substantially all of the assets of the Company, other than in the ordinary
course of business, or a sale or transfer of capital stock of the Company (other
than the sale of stock in the IPO) resulting in a change in the ownership of a
majority of the voting capital stock of the Company, or a merger or
consolidation having the effect of such a sale of capital stock.

         3. Events Upon Which Option Becomes Exercisable. The Option shall be
exercisable, for the period indicated, solely upon the first to occur of the
following events, in each case subject to prior termination pursuant to
paragraph 2 above:

            (a) During the five year period commencing with the 180th day

            (c) During the one-month period commencing with a Sale of the
Company.

         4. Manner of Exercise. During the period, if any, that the Option is
exercisable, the Optionee may exercise the Option with respect to all or any
part of the shares then subject to the Option, by giving the Company written
notice of such exercise, which notice shall be in such form as may from time to
time be specified by the Committee. Such notice shall specify the number of
shares as to which the Option is so exercised and shall be accompanied by full
payment for all the shares being purchased. The option price shall be payable in
cash, by check


<PAGE>



or by tendering to the Company shares of Common Stock having an aggregate fair
market value, determined as of the date of payment by the Board of Directors of
the Company (the "Board"), equal to the option price.

         5. Non-Transferability. During the lifetime of the Optionee, the Option
shall be exercisable only by him and shall not be assignable or transferable by
him, and no other person shall acquire any rights therein, the Option being
transferable by the Optionee only by will or the laws of dissent and
distribution.

         6. Adjustment in the Event of Recapitalization. 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 shall make such
adjustment as it may deem equitably required, in the number and kind of shares
covered by the Option and in the option price.

         7. Notices. Any notice to the Company provided for in this Stock Option
Agreement shall be addressed to it in care of its Secretary, at its principal
executive offices, and any notice to the Optionee shall be addressed to him at
his address at the time as it is shown on the records of the Company, or to such
other address as either may designate to the other in writing. Any such notice
shall be in writing and shall be deemed to be fully given if delivered by hand
or sent by telegram or by registered or certified mail, postage prepaid,
addressed as stated above.

         8. Miscellaneous. All references herein shall include the singular and
the plural and the masculine, feminine and the neuter, as applicable. This Stock
Option Agreement replaces and supersedes all agreements and understandings
between the Company, Woodburn and the Optionee with respect to the subject
matter hereof. This Stock Option Agreement is subject to modification or
amendment solely upon a written agreement signed by the Company and the


<PAGE>


Optionee. The validity, construction, interpretation and effect of this Stock
Option Agreement shall be exclusively governed by and determined in accordance
with the laws of the Commonwealth of Pennsylvania.
