                               EXPLANATORY NOTE 

   This Registration Statement contains two forms of prospectus: (i) one to 
be used in connection with an offering by the Company of shares of Common 
Stock and Redeemable Common Stock Purchase Warrants (the "Prospectus") and 
(ii) one to be used in connection with the sale of Redeemable Common Stock 
Purchase Warrant and shares of Common Stock issuable upon exercise of those 
Redeemable Common Stock Purchase Warrants and outstanding options by certain 
selling securityholders (the "Selling Securityholder Prospectus"). The 
Prospectus and the Selling Securityholder Prospectus will be identical in all 
respects except for the alternate pages for the Selling Securityholder 
Prospectus included herein which are labeled "Alternate Page for Selling 
Securityholder Prospectus."

The information contained herein is subject to completion or amendment. A 
registration statement relating to these securities has been filed with the 
Securities and Exchange Commission. These securities may not be sold nor may 
offers to buy be accepted prior to the time the registration statement 
becomes effective. This prospectus shall not constitute an offer to sell or 
the solicitation of an offer to buy nor shall there be any sale of these 
securities in any State in which such offer, solicitation or sale would be 
unlawful prior to registration or qualification under the securities laws of 
any such State. 
   
     PRELIMINARY PROSPECTUS, SUBJECT TO COMPLETION, DATED MARCH 14, 1997 
                                 UNIVEC, INC. 
                     1,500,000 SHARES OF COMMON STOCK AND 
             2,250,000 REDEEMABLE COMMON STOCK PURCHASE WARRANTS 

   This Prospectus relates to an offering (the "Offering") by UNIVEC, Inc. 
(the "Company") of 1,500,000 shares of common stock, par value $.001 per 
share (the "Common Stock"), and 2,250,000 redeemable common stock purchase 
warrants (the "Warrants"). The shares of Common Stock and the Warrants 
offered hereby may be purchased separately and will be transferable 
separately after issuance. The Common Stock is being offered at $3.50 per 
share and the Warrants at $.10 per Warrant. 

   Each Warrant entitles the registered holder thereof to purchase one share 
of Common Stock at an exercise price of $4.50 per share, subject to 
adjustment in certain events, at any time during the period commencing 
__________, 1999 [two years after the date upon which the Registration 
Statement of which this Prospectus forms a part is declared effective by the 
Securities Exchange Commission (the "Effective Date")] and expiring on 
____________, 2002 [the fifth anniversary of the Effective Date]. The 
Warrants are subject to redemption by the Company at $.05 per Warrant at any 
time commencing _______________, 1999 [two years after the Effective Date] 
(with the prior written consent of Maidstone Financial, Inc., the 
representative of the Underwriters (the "Representative")), on not less than 
30 days prior written notice to the holders of the Warrants, provided the 
closing bid price of the Common Stock had been at least $8.00 for 20 
consecutive trading days ending on the third day prior to the date on which 
the Company gives notice of redemption. The Warrants will be exercisable 
until the close of business on the day immediately preceding the date fixed 
for redemption. The Company has applied for quotation of the Common Stock and 
the Warrants on The Nasdaq SmallCap Market under the trading symbols "UNVC" 
and "UNVCW", respectively. See "Description of Securities -- Warrants." 

   Prior to the Offering, there has been no public market for the Common 
Stock or Warrants, and there can be no assurance that any such market for the 
Common Stock or Warrants will develop after the closing of the Offering, or 
that, if developed, it will be sustained. The offering prices of the Common 
Stock and Warrants and the terms of the Warrants were established by 
negotiations between the Company and the Representative and do not 
necessarily bear any direct relationship to the Company's assets, earnings, 
book value per share or other generally accepted criteria of value. 

   The Company has registered for resale under a separate prospectus (the 
"Selling Securityholder Prospectus") as part of the Registration Statement 
warrants to purchase 2,500,000 shares of Common Stock (having terms identical 
to the warrants offered hereby) and the shares of Common Stock issuable upon 
exercise thereof, and 33,436 shares of Common Stock issuable upon exercise of 
options. The warrants were issued in connection with a bridge financing 
completed by the Company in December 1996. Prior to the Effective Date, each 
of the selling securityholders named in the Selling Securityholder Prospectus 
will enter into an agreement not to sell or otherwise dispose of any 
securities of the Company for a period of 24 months following the Effective 
Date, without the prior written consent of the Representative. The Company 
will not receive any proceeds from the sale of the warrants or shares of 
Common Stock by the selling securityholders, but will receive the exercise 
price of the warrants and options exercised. See "Selling Securityholder 
Offering."

With the aspirating syringe, the UNIVEC locking clip does not limit the user's
ability to withdraw and depress ("to aspirate") the plunger until the user locks
the syringe voluntarily.

With the non-aspirating syringe, the UNIVEC locking clip limits the user's
ability to aspirate the plunger and locks the syringe passively.

(1) Does not include additional compensation consisting of (i) a 
    non-accountable expense allowance payable to the Representative equal to 
    3% of the gross proceeds of the Offering, of which $55,000 has been paid 
    by the Company to date, (ii) warrants (the "Underwriters' Warrants") 
    entitling the Underwriters to purchase an amount equal to 10% of the 
    number of shares of Common Stock and Warrants offered hereby (excluding 
    the Over-Allotment Option, as defined in footnote 3, below) for a 
    purchase price of 165% of the initial public offering price thereof, and 
    (iii) a financial advisory agreement with the Representative for 24 
    months commencing on the date of the closing of the Offering for a fee of 
    $4,000 per month, or an aggregate of $96,000, payable in its entirety at 
    the closing of the Offering. In addition, the Company has agreed to pay 
    the Representative, under certain circumstances, a warrant solicitation 
    fee of 8% of the exercise price of each Warrant exercised and to 
    indemnify the Underwriters against certain civil liabilities, including 
    those arising under the Securities Act. See "Underwriting." 

(2) After deducting discounts and commissions payable to the Underwriters, 
    but before payment of the Representative's non-accountable expense

    exercised in full), the financial advisory fee ($96,000) and the other 
    expenses of the Offering (estimated at $383,000) payable by the Company.

    period of 45 days after the closing of the Offering, to purchase up to an 
    additional 15% of the shares of Common Stock and/or Warrants offered 
    hereby, upon the same terms and conditions solely for the purpose of 
    covering over-allotments, if any (the "Over-Allotment Option"). If the 
    Over-Allotment Option is exercised in full, the total Price to Public, 
    Underwriting Discounts and Commissions and Proceeds to Company will be 
    $6,296,250, $629,625 and $5,666,625, respectively. See "Underwriting." 

   The Common Stock and Warrants are being offered by the Underwriters on a 
"firm commitment" basis, subject to prior sale, when, as and if delivered to

                              PROSPECTUS SUMMARY 

   The following summary is qualified in its entirety by the more detailed 
information and consolidated financial statements appearing elsewhere in this 
Prospectus. Unless otherwise indicated or the context otherwise requires, all 
references herein to the Company or UNIVEC include UNIVEC, Inc., a New York 
corporation ("UNIVEC-NY"), which was merged into the Company on October 10, 
1996, and R/ Ultra, Inc., a wholly owned subsidiary of UNIVEC. Except as 
otherwise stated, all information assumes no exercise of the Over-Allotment 
Option. 

                                 THE COMPANY 

   
   UNIVEC, Inc. (the "Company" or "UNIVEC") develops and markets safety 
hypodermic syringes designed to protect the healthcare worker and patient 
against cross-infection. The Company also sells and intends to develop other 
hypodermic devices. In January 1997, the Company commenced production and 
sales of its 1cc locking clip syringes, which are designed to make accidental 
or deliberate reuse difficult. The accidental or deliberate reuse of syringes 
is a frequent cause of the spread of the human immunodeficiency ("HIV") and 
hepatitis viruses, as well as other blood-borne pathogens. The Company has 
received 510(k) clearance from the U.S. Food and Drug Administration (the 
"FDA") to market its locking clip syringes in the United States. In the first 
two months of 1997, the Company sold approximately 1,777,000 locking clip 
syringes resulting in sales of approximately $159,000. 

   Public health officials have encouraged the medical industry to develop 
safer, more difficult to reuse, syringes, to prevent the spread of 
blood-borne pathogens, such as HIV and hepatitis. In 1995, the House of 
Delegates -- American Medical Association requested "manufacturers of 
disposable hypodermic needles and syringes to adopt designs to prevent reuse 
and to include in the packaging clear directions for their correct disposal." 
In late 1995, UNICEF recommended "the use of auto-destruct syringes instead 
of disposable, single use syringes in order to avoid the hazards of unsafe 
injection practices." In 1996, Brazil adopted a law requiring disposable 
syringes manufactured or marketed in that country to include a safety device 
to prevent its reuse. During 1996, New York State enacted legislation 
authorizing a limited number of pilot projects to test the practicality and 
effectiveness of difficult to reuse syringes. Such pilot tests are to be 
conducted, subject to funding, in state-operated facilities, such as prisons, 
hospitals, youth detention facilities and development centers. 

   The Company believes that its 1cc difficult to reuse syringes are more 
effective than competitive syringes and that they are competitively priced. 
The Company also believes that it is the only company that markets a 
difficult to reuse syringe with a 1cc barrel, which is ideal for dispensing 
 .05cc to .95cc dosages of medicine (e.g., allergy, immunization and insulin 
medicines). It is more difficult to deliver .05cc to .95cc dosages accurately 
with a syringe barrel that is greater than 1cc. The Company does not know of 
any other company that offers an aspirating syringe that can be locked. 
Healthcare workers need aspirating syringes to mix medications in the syringe 
barrel and inject medications intravenously. Furthermore, the Company 
believes that aspirating syringes are preferred by diabetes patients and 
needle-exchange programs. 
    

   The Company's syringes will be assembled primarily by Harmac Medical 
Products, Inc. ("Harmac"), one of the largest independent, privately-owned 
contract manufacturers of disposable medical products in the United States, 
using assembly and packaging equipment supplied by the Company. Sherwood 
Davis & Geck ("Sherwood"), a subsidiary of American Home Products, will 
supply most of the components for the syringes assembled by Harmac. Some of 
the Company's syringes and its proprietary aspirating plunger will be 
manufactured by INSERPOR, a contract manufacturer in Portugal. 

   
   The Company's initial marketing efforts will be directed primarily to 
UNICEF, the World Health Organization ("WHO") and public hospitals and health 
facilities in New York. The Company also intends to market its locking clip 
syringes to (i) governments of developing countries, (ii) private hospitals 
and health facilities in New York, New Jersey and Connecticut, and (iii) 
retail distributors in the United States. 
    

                                      5 
<PAGE>

The Company also plans to license its patents and proprietary manufacturing 
processes relating to its locking clip and other syringe designs to 
established medical device manufacturers. To stimulate demand for its safety 
syringes, the Company plans to initiate promotional and educational campaigns 
directed at (i) public health officers and other government officials 
responsible for public health policies, (ii) doctors and administrators of 
healthcare facilities responsible for treatment of HIV-AIDS patients, and 
(iii) liability insurance companies. The Company plans to enter into 
arrangements with independent sales agents and distributors in targeted 
markets and to hire a marketing director following the completion of the 
Offering. 

   The Company is a Delaware corporation, incorporated on October 7, 1996, 
and the successor by merger to UNIVEC, Inc., a New York corporation, 
incorporated on August 18, 1992. The executive officers of the Company are 
located at 999 Franklin Avenue, Garden City, New York 11530 (telephone number 
(516) 294-1000).

                                 RISK FACTORS 

   The securities offered hereby are speculative and involve a high degree of 
risk, including but not limited to the risk factors described below. Each 
prospective investor should carefully consider the following risk factors 
before making an investment decision. 

   
   1. Continuing Losses; Accumulated Deficit; Working Capital Deficit.  Since 
inception, the Company has experienced losses, including a net loss of 
approximately $1,441,000 (on sales of approximately $461,000) for the year 
ended December 31, 1996, as compared to a net loss of approximately $946,000 
(on sales of approximately $1,107,000) for the year ended December 31, 1995. 
The Company expects to continue to incur operating losses until such time, if 
ever, as it can generate significant sales of its locking clip syringes and 
reduce the cost of sales of its locking clip syringes on a per unit basis so 
that it can realize adequate gross profits to cover overhead expenses. There 
can be no assurance that the Company will ever operate profitably. As of 
December 31, 1996, the Company had an accumulated deficit of approximately 
$4,253,000 and a working capital deficit of approximately $1,067,000. The 
Company's ability to operate profitably depends upon market acceptance of its 
locking clip syringes, the development of an effective sales and marketing 
organization, the development of new products, and improvements to existing 
products and manufacturing processes. There can be no assurance that the 
Company's locking clip syringes will achieve a level of market acceptance in 
foreign or domestic markets to generate sufficient revenues to become 
profitable. See "Management's Discussion and Analysis of Financial Condition 
and Results of Operations" and the Company's consolidated financial 
statements, including the notes thereto, appearing elsewhere herein. 

   2. "Going Concern." The Company's consolidated financial statements for 
the year ended December 31, 1996, indicate there is substantial doubt about 
the Company's ability to continue as a going concern due to the Company's 
need to generate cash from operations and obtain additional financing. See 
"Management's Discussion and Analysis of Financial Condition and Results of 
Operations" and "Report of Independent Accountants" on the Company's 
consolidated financial statements appearing at page F-2 hereof. 

   3. Limited Operating History.  Although the Company commenced operations 
in August 1992, its operations have consisted primarily of the design of its 
patented locking clip and plunger, the design of the manufacturing processes 
and equipment for production of the locking clip, the hiring of key 
personnel, formulation of a marketing plan for the sale of its syringes, and 
the negotiation of production and supply agreements with contract 
manufacturers and suppliers of components to be used in the production of its 
syringes. Accordingly, the Company has a limited operating history upon which 
an evaluation of its business and prospects can be based. An investment in 
the securities of the Company is subject to all of the risks involved in a 
newly established business venture. Potential investors should be aware of 
the problems, delays, expenses and difficulties encountered by companies at 
this early stage of operations, many of which may be beyond the Company's 
control, including but not limited to commencement of production, marketing 
and product introduction, competition, market acceptance of the Company's 
difficult to reuse syringes, and unanticipated problems and additional costs 
relating to the development and testing of products. The Company's officers 
have limited experience in the production and sale of medical devices. See 
"Management's Discussion and Analysis of Financial Condition and Results of 
Operations," "Risk Factors -- Limited Experience of Management in the 
Production and Sale of Medical Devices" and "Management." 
    

   4. Ability to Manage Growth. The Company contemplates a rapid expansion of 
its business. If the Company were to experience significant growth in the 
future, such growth would likely result in new and increased responsibilities 
for management personnel and place significant strain upon the Company's 
management, operating and financial systems and resources. To accommodate 
such growth and compete effectively, the Company must continue to implement 
and improve its operational, financial, management and information systems, 
procedures and controls, and to expand, train and manage its personnel. There 
can be no assurance that the Company's personnel, systems, procedures and 
controls will be adequate to support the Company's future operations. Any 
failure to implement and improve the Company's operational, financial, 
management and information systems, procedures or controls or to expand, 
train or manage employees, could materially and adversely affect the 
Company's business, financial condition and results of operations. See "Use 
of Proceeds," "Risk Factors -- Dependence on Key Personnel," "Business -- 
Employees" and "Management -- Directors, Executive Officers and Key 
Employees." 

                                      9

   5. Government Regulation. The manufacture and distribution of medical 
devices are subject to extensive regulation by the FDA and, in some 
instances, by foreign and state governments. Approval by the FDA and foreign 
government authorities is unpredictable and uncertain, and no assurance can 
be given that the necessary approvals or clearances for the Company's 
products will be granted on a timely basis or at all. Delays in receipt of, 
or a failure to receive, such approvals or clearances, or the loss of any 
previously received approvals or clearances, could have a materially adverse 
effect on the business, financial condition and results of operations of the 
Company. Furthermore, approvals that have been or may be granted are subject 
to continual review, and later discovery of previously unknown problems may 
result in product labeling restrictions or withdrawal of the product from the 
market. Moreover, changes in existing requirements or adoption of new 
requirements or policies could adversely affect the ability of the Company to 
comply with regulatory requirements. In addition, there can be no assurance 
that the Company will not be required to incur significant costs to comply 
with applicable laws and regulations in the future. Failure to comply with 
applicable laws or regulatory requirements could have a materially adverse 
effect on the Company's business, financial position and results of 
operations. See "Business -- Government Regulation." 

   
   FDA and State Regulation. Pursuant to the Federal Food, Drug, and Cosmetic 
Act, as amended, and the regulations promulgated thereunder (collectively, 
the "FDC Act"), the FDA regulates the clinical testing, manufacture, 
labeling, sale, distribution and promotion of medical devices. Before a new 
device can be introduced into the market, a manufacturer must obtain FDA 
permission to market through either the 510(k) pre-market notification 
process or the costlier, lengthier and less certain pre-market approval 
("PMA") application process. The FDA has granted the Company 510(k) clearance 
to market its 1cc locking clip syringe, which has been classified as a Class 
II device under the FDC Act, and accordingly, the Company may market and sell 
its 1cc locking clip syringe in the United States, subject to compliance with 
other applicable FDA regulatory requirements. As a Class II device, 
performance standards may be developed for the 1cc locking clip syringe which 
the product would then be required to meet. Failure to meet those standards 
would require the Company to discontinue the marketing of the product. 
Furthermore, manufacturers of medical devices are subject to recordkeeping 
requirements and required to report adverse experiences relating to the use 
of the device. Device manufacturers also are required to register their 
establishments and list their devices with the FDA and with certain state 
agencies and are subject to periodic inspections by the FDA and certain state 
agencies. The FDC Act requires devices to be manufactured in accordance with 
good manufacturing practices ("GMP") regulations, which impose certain 
procedural and documentation requirements upon the Company with respect to 
manufacturing and quality assurance activities. The FDA conducts periodic 
audits and surveillance of the manufacturing, sterilizing and packaging 
facilities of medical device manufacturers to determine compliance with GMP 
requirements. The failure of a medical device manufacturer to be able to show 
in the audit or post-market surveillance that it has adequately complied with 
GMP requirements can result in penalties or enforcement proceedings being 
imposed on the manufacturer. Harmac's facilities will be subject to extensive 
audits in the future, pursuant to standard FDA procedure. No assurance can be 
given that when Harmac is audited that it will be found to be in compliance 
with GMP requirements, or that if it is not found in compliance, what 
penalties, enforcement procedures or compliance effort will be levied on or 
required of Harmac and/or the Company. Recently adopted GMP requirements, 
including those pertaining to design control, are likely to increase the cost 
of GMP compliance. Noncompliance with applicable FDA requirements, including 
GMP regulations, can result in, among other things, fines, injunctions, civil 
penalties, recall or seizure of products, total or partial suspension of 
production, failure of the government to grant pre-market clearance or 
pre-market approval for devices, withdrawal of marketing approvals, and 
criminal prosecution. The FDA also has the authority to request repair, 
replacement or refund of the cost of any device manufactured or distributed 
by the Company. 

   Foreign Regulations. The introduction of the Company's products in foreign 
markets will subject the Company to foreign regulatory clearances which may 
impose additional substantive costs and burdens. The Company's products are 
required to satisfy international manufacturing standards required by the 
International Standards Organization ("ISO") for sale in certain foreign 
countries. Although Harmac expects to achieve ISO 9001 certification by the 
end of the second quarter of 1997, until Harmac obtains ISO 9001 
certification, the Company will have difficulty selling to some export 
accounts, particularly in Europe. International sales of medical devices are 
subject to the regulatory requirements of each country. The regulatory review 
process varies from country to country. Many countries also impose product 
standards, packaging requirements, labeling requirements and import 
restrictions on devices. In addition, each country has its own tariff 
regulations, duties and tax requirements. 
    

                                      10

   6. Product Acceptance; Demand for Locking Clip Syringes. The Company 
expects to derive a significant portion of its revenues from sales of locking 
clip syringes and/or licensing of its intellectual property. Despite 
increased public awareness of the risks associated with conventional 
disposable syringes, of the major syringe manufacturers only Becton-Dickinson 
is manufacturing a difficult to reuse syringe for sale to UNICEF and WHO. 
Accordingly, the Company's future success and financial performance will 
depend almost entirely on its ability to successfully market its locking clip 
syringes. There can be no assurance that the Company's marketing efforts will 
be successful or that sales of the Company's difficult to reuse syringes will 
generate sufficient revenues for the Company to become profitable. Export 
sales, particularly in Europe, may be adversely affected until the Company's 
contract manufacturers are able to manufacture the Company's syringes in 
accordance with manufacturing standards required by the International 
Standards Organization. See "Management's Discussion and Analysis of 
Financial Condition and Results of Operations" and "Business." 

   7. Licensing. The Company intends to license its patents and proprietary 
manufacturing processes relating to its locking clip and other syringe 
designs to established medical device manufacturers worldwide. Although the 
Company has granted Sherwood an option for a non-exclusive license to 
manufacture and sell the Company's locking clip syringe in the United States, 
there can be no assurance that Sherwood will exercise the option, that others 
will enter into license arrangements with the Company, or that the Company 
will be successful in its licensing efforts. See "Business." 

   
   8. Dependence on Certain Customers. The Company's initial marketing 
efforts have been directed, to a significant extent, to relief agencies, 
including UNICEF and WHO, which administered almost one billion injections to 
women and children through immunization programs in developing countries in 
1995. The Company does not have a legally binding commitment from UNICEF or 
WHO and there can be no assurance as to the number of locking clip syringes 
which UNICEF or WHO will purchase from the Company. The failure of UNICEF, 
WHO or other relief agencies to purchase the Company's locking clip syringes 
in substantial quantities would have a materially adverse effect on the 
Company's business, financial condition and results of operations. See 
"Business." 
    

   Furthermore, in 1996, New York State enacted legislation authorizing a 
limited number of pilot projects to test the practicality and effectiveness 
of difficult to reuse syringes. Such pilot tests are to be conducted, subject 
to funding, in state-operated facilities, such as prisons, hospitals, youth 
detention facilities, and development centers. New York State officials have 
expressed an intent to buy the Company's syringes. However, the Company does 
not have a legally binding commitment from purchasing agents for any of the 
New York state- operated facilities, and there can be no assurance as to the 
number of locking syringes which New York state- operated facilities will 
purchase from the Company, if any. 

   
   9. Dependence on Certain Suppliers. The Company has entered into a letter 
of understanding with INSERPOR, a Portuguese syringe manufacturer, for the 
assembly of syringes ordered by relief agencies such as WHO, as long as 
INSERPOR can supply the required volume of syringes. If INSERPOR is unable or 
not willing to supply a sufficient quantity of components, the Company would 
seek to purchase additional quantities of components from alternative 
suppliers, such as Sherwood. However, there can be no assurance that the 
Company would be able to obtain sufficient quantities of the syringe and 
related components required to fill orders from relief agencies from 
alternative suppliers. In addition, the Company is dependent upon INSERPOR to 
supply the Company's proprietary plunger which satisfies tolerance limits for 
assembly of its aspirating syringe. If INSERPOR is unable or not willing to 
supply sufficient quantities of the Company's proprietary plunger which 
satisfies such tolerance limits, the Company will be required to obtain 
alternative sources of supply. The Company has commenced discussions with 
Harmac to mold the aspirating plunger; however, there can be no assurance 
that the Company will be able to obtain an alternative source of supply on 
acceptable terms. Furthermore, if the Company is able to obtain an 
alternative source of supply, there can be no assurance that production of 
its aspirating syringes will not be delayed. The Company's failure to obtain 
an alternate supplier for its proprietary plunger or delays resulting from 
the selection of an alternate supplier could have a materially adverse effect 
on the Company's business. See "Business -- Suppliers." 
    

   The Company is dependent upon Sherwood for supplying syringe component 
sets for the production of its locking clip syringes for other customers. 
Pursuant to its supply agreement with the Company, Sherwood is only 

                                      11 
<PAGE>

obligated to deliver 4,166,667 component sets per month. There can be no 
assurance that Sherwood will be able to supply component sets in excess of 
that amount if the Company receives orders for syringes in excess thereof, or 
that the Company will be able to obtain additional component sets from 
alternative sources of supply on favorable terms, if at all. Failure to 
obtain an adequate supply of syringes and related components could result in 
the cancellation of orders and consequently, could have a materially adverse 
effect on the Company's business. The Company also is dependent upon Sherwood 
to supply the Company's proprietary plunger which satisfies tolerance limits 
for assembly of its non-aspirating syringe. If Sherwood is unable to supply 
sufficient quantities of the Company's proprietary plunger which satisfies 
such tolerance limits, the Company will be required to obtain alternative 
sources of supply. The Company has commenced discussions with Harmac to mold 
the non-aspirating plunger; however, there can be no assurance that the 
Company will be able to obtain an alternative source of supply on acceptable 
terms. See "Business -- Suppliers." 

   
   10. Dependence on Certain Assemblers. The Company has entered into a 
manufacturing agreement with Harmac for the assembly of the Company's locking 
clip syringes. The equipment which the Company has supplied Harmac with for 
the assembly of 1cc syringes only is capable of producing 36 million syringes 
per year. With improvements to manufacturing processes at Harmac, the Company 
expects to increase capacity to 80 million syringes per year and to decrease 
its cost of sales on a per unit basis. However, there can be no assurance 
that the Company will be able to increase the production capacity at Harmac. 
Furthermore, there can be no assurance that Harmac will produce syringes at 
costs sufficiently less than the Company's selling prices so that gross 
profits are adequate to cover overhead expenses. See "Business -- 
Production." 

   The Company has entered into a letter of understanding with INSERPOR for 
the assembly of the Company's non-aspirating, locking syringes for WHO and 
other UN-related immunization programs, as long as INSERPOR can supply the 
required volume of syringes. During the first two months of 1997, INSERPOR 
assembled approximately 1,777,000 locking clip syringes. INSERPOR is capable 
of producing 30 million syringes per year, subject to certain modifications 
to existing assembly equipment and additional equipment to subassemble the 
clip to the plunger (clip assembly line). The Company expects to purchase the 
clip assembly line with a portion of the net proceeds of the Offering. 
Currently, INSERPOR is capable of producing only 12 million syringes per 
year. The Company believes that INSERPOR will be able to increase its 
production capacity to 30 million syringes per year within twelve months 
following the completion of the Offering. There can be no assurance that 
INSERPOR will produce quantities of syringes at costs sufficiently less than 
the Company's selling prices so that gross profits are adequate to cover 
overhead expenses. See "Business -- Production." 

   11. Delays in Establishing Production. Although the Company expects to 
commence production of its locking clip syringes at Harmac's facilities 
before the end of March 1997, there can be no assurance that the commencement 
of production will not be delayed as a result of delays in complying with GMP 
requirements, including the attainment of acceptable quality levels. The 
failure to timely commence production would delay receipt of revenues and 
would have a materially adverse effect on the Company's business, financial 
condition and results of operations. 

   12. Limited Experience of Management in the Production and Sale of Medical 
Services. The Company's management has had limited experience in the 
production and sale of medical devices. There can be no assurance that the 
Company will be able to compete successfully with the major syringe 
manufacturers. See "Risk Factors -- Limited Operating History," "Risk Factors 
- -- Competition" and "Management." 

   13. Ability to Develop 3cc Syringe. The Company intends to develop 3cc 
locking clip syringes for hospitals and health clinics in 1997, and 
anticipates that production of the non-aspirating model will commence by 
1998. In general, hospitals and health clinics use more 3cc syringes than 1cc 
syringes, and may not be willing to purchase the Company's 1cc locking clip 
syringes until such time as the Company is able to offer 3cc syringes. 
However, there can be no assurance that the 3cc designs selected for 
commercialization will be accepted by hospitals and health clinics. Moreover, 
the Company has not yet selected a product design for its aspirating model, 
nor has it selected a design for the assembly equipment or an engineering 
firm to construct the equipment. The Company's failure to timely select a 
design for an aspirating model, a design for assembly equipment, or an 
engineering firm to construct such assembly equipment could delay the 
production and commercial introduction of the Company's 3cc syringe. 
Depending on the design selected, the Company may be required to obtain 
510(k) clearance from the FDA prior to commencing commercial sales of its 3cc 
aspirating syringes in the United States. See "Business." 
    

                                      12 
<PAGE>

   
   14. Uncertainty Regarding Patents and Protection of Proprietary 
Technology; Risk of Future Litigation. The Company's success will depend, in 
part, on the strength of its patents, as well as its ability to preserve its 
trade secrets and operate without infringing the proprietary rights of 
others. The Company's policy is to seek protection of its proprietary 
position by, among other methods, filing United States and foreign patent 
applications related to its technology, inventions and improvements that are 
important to the development of its business. The Company holds three United 
States patents, including a patent for its locking clip and has filed a 
United States patent application for its aspirating plunger, and has filed 
patent applications for its locking clip in Canada, Brazil, Mexico, certain 
European countries, Japan, South Korea, China, Russia and Australia. In 
addition, the Company has acquired licensed rights for United States patents 
on three other locking devices, which utilize different locking apparatuses 
or methods than those claimed by the UNIVEC clip patents. The Company 
licensed these patents to develop a 3cc locking syringe. The Company has 
filed for patent protection in certain European Countries for one of these 
licenses, which may be used in connection with the 3cc non- aspirating 
syringe that the Company plans to develop. 
    

   There can be no assurance that pending or future applications for patents 
and trademarks will mature into issued patents, or that the Company will 
continue to develop its own patentable technologies. Furthermore, there can 
be no assurance that any of the Company's patents or patents that may be 
issued in the future will not be challenged, invalidated or circumvented in 
the future or that the rights granted thereunder will provide a competitive 
advantage. In addition, patent applications filed in foreign countries and 
patents granted in such countries are subject to laws, rules and procedures 
that differ from those in the United States. Patent protection in such 
countries may be different from patent protection provided by the laws of the 
United States. 

   Patent applications in the United States are maintained in secrecy until 
patents issue, and patent applications in foreign countries are maintained in 
secrecy for a period after filing. Publication of discoveries in the 
scientific or patent literature tends to lag behind actual discoveries and 
the filing of related patent applications. Accordingly, there can be no 
assurance that current and potential competitors and other third parties have 
not filed or in the future will not file applications for, or have not 
received or in the future will not receive, patents or obtain additional 
proprietary rights that will prevent, limit or interfere with the Company's 
ability to make, use or sell its products either in the United States or 
internationally. 

   The medical device industry in general has been characterized by 
substantial competition and litigation regarding patent and other proprietary 
rights. The Company intends to vigorously protect and defend its patents and 
other proprietary rights relating to its proprietary technology. Litigation 
alleging infringement claims against the Company (with or without merit), or 
instituted by the Company to enforce patents and to protect trade secrets or 
know-how owned by the Company or to determine the enforceability, scope and 
validity of the proprietary rights of others, is costly and time consuming. 
If any relevant claims of third-party patents are upheld as valid and 
enforceable in any litigation or administrative proceedings, the Company 
could be prevented from practicing the subject matter claimed in such 
patents, or would be required to obtain licenses from the patent owners of 
each patent, or to redesign its products or processes to avoid infringement. 
There can be no assurance that such licenses would be available or, if 
available, would be available on terms acceptable to the Company or that the 
Company would be successful in any attempt to redesign its products or 
processes to avoid infringement. Accordingly, an adverse determination in a 
judicial or administrative proceeding or failure to obtain necessary licenses 
could prevent the Company from manufacturing and selling its products, which 
would have a materially adverse effect on the Company's business, financial 
condition and results of operations. 

   The Company also relies upon trade secrets, technical know-how and 
continuing technological innovation to develop and maintain its competitive 
position. There can be no assurance that competitors will not independently 
develop substantially equivalent proprietary information and techniques or 
otherwise gain access to the Company's proprietary technology, or that the 
Company can meaningfully protect its rights in unpatented proprietary 
technology. See "Business -- Patents and Proprietary Rights" and "Risk 
Factors -- Competition." 

   
   15. Competition. The Company's principal competition is from manufacturers 
of traditional disposable syringes. Becton-Dickinson and Company 
("Becton-Dickinson"), Sherwood and Terumo Medical Corporation of Japan 
("Terumo") control approximately 74%, 19% and 5%, respectively, or a total of 
approximately 98%, of the worldwide syringe market, and are substantially 
larger, more established and have significantly greater financial, sales and 
marketing, distribution, engineering, research and development and other 
resources than the 
    

                                      13 
<PAGE>

Company. To the Company's knowledge, only Becton-Dickinson and Bader & 
Partner Medizintechnik GmbH ("Bader"), a German machine tool manufacturer, 
distribute commercially a line of difficult to reuse syringes, none of which 
allow for aspiration. The Bader DestroJect syringe and the Becton-Dickinson 
SOLOSHOT syringe were developed originally for WHO-UNICEF immunization 
programs. There can be no assurance that the major syringe manufacturers or 
others will not commence production of difficult to reuse syringes, or that 
the Company will be able to successfully compete in this market. See 
"Business -- Difficult to Reuse Syringes" and "Business -- Competition." 

   
   16. Dependence on Third Parties for Marketing; Limited Marketing 
Experience.  The Company intends to sell its products primarily through sales 
agents and third-party distributors and may, on a limited basis, sell 
products independently. The Company has entered into a limited number of 
agreements with sales agents for the sale of its products. There can be no 
assurance that the Company will be able to obtain satisfactory arrangements 
with sales agents or distributors or that the Company will generate 
substantial revenues from sales by sales agents and distributors. 

   17. Reliance on Foreign Sales. The Company believes that a significant 
portion of its revenues will be derived from the sale of its locking clip 
syringes in foreign markets, which will result in the Company being subject 
to risks associated with foreign sales, including economic or political 
instability, shipping delays, fluctuations in foreign currency exchange 
rates, custom duties and export quotas and other trade restrictions, any of 
which could have a materially adverse effect on the Company's business. 
Although the Company intends to negotiate confirmed (irrevocable) letters of 
credit and to transfer product title to the buyer when delivered to the 
shipper (f.o.b. warehouse), there is no assurance that such terms will be 
acceptable to customers. 

   18. Product Liability. The manufacture and sale of medical products 
exposes the Company to the risk of significant damages from product liability 
claims. The Company maintains product liability insurance against product 
liability claims in the amount of $5 million per occurrence and $5 million in 
the aggregate. The Company also has applied for recall insurance, although 
there can be no assurance that such coverage can be obtained at acceptable 
cost. There can be no assurance that the coverage limits of the Company's 
insurance policies will be adequate, that the Company will continue to be 
able to procure and maintain such insurance coverage, that such insurance can 
be maintained at acceptable costs, or that customers will be able to satisfy 
indemnification claims. In addition, any successful claim against the Company 
in an amount exceeding its insurance coverage could have a materially adverse 
effect on its business, financial condition or results of operations. 

   19. Control of the Company; Ownership of Shares by Directors and 
Officers.  Upon completion of the Offering, officers and directors of the 
Company will beneficially own in the aggregate approximately 43% of the 
outstanding shares of the Company's Common Stock. Although these stockholders 
may or may not agree on any particular matter that is the subject of a vote 
of the stockholders, these stockholders may be effectively able to control 
the outcome of any issues which may be subject to a vote of stockholders, 
including the election of directors, proposals to increase the authorized 
capital stock, or the approval of mergers, acquisitions, or the sale of all 
or substantially all of the Company's assets. See "Security Ownership of 
Certain Beneficial Owners and Management." 

   20. Dependence on Management. The Company is dependent for the conduct of 
its business on the experience, abilities and continued services of Joel 
Schoenfeld, Chairman of the Board and Chief Executive Officer of the Company, 
Dr. Alan H. Gold, President and a Director of the Company, David Shonfeld, 
Director of Research and Development and a Director of the Company, and David 
Chabut, Chief Financial Officer of the Company. The Company is dependent upon 
Joel Schoenfeld for strategy, marketing and general management, Dr. Alan H. 
Gold for functional definition of its products, David Shonfeld for product 
design to meet functional requirements and David Chabut for financial 
management. Joel Schoenfeld, David Shonfeld and David Chabut are employed by 
the Company pursuant to employment agreements which expire on March 28, 2000, 
July 31, 1997 and September 30, 1997, respectively. Dr. Alan H. Gold is 
professionally employed by, and is the President of, the Long Island Plastic 
Surgical Group, and he only works part-time with the Company. Although David 
Shonfeld is compensated on an hourly basis, he currently is working on a 
full-time basis for the Company. The Company does not have key-man insurance 
on the life of any of its executive officers. The Company has applied for 
key-man insurance on the lives of Joel Schoenfeld and David Chabut, each in 
the amount of $1,000,000; 
    

                                      14 
<PAGE>

   
however there can be no assurance that such insurance can be obtained at 
acceptable cost. Furthermore, there is no plan of succession if one or more 
of the Company's officers dies or becomes disabled. The loss of the services 
of Joel Schoenfeld, Dr. Alan H. Gold, David Shonfeld or David Chabut could 
have a materially adverse effect on the Company. See "Management." 

   21. Broad Discretion in the Application of Net Proceeds. Approximately 
$987,250, or approximately 23% of the net proceeds of the Offering have been 
allocated to working capital and general corporate purposes. Accordingly, 
management will have broad discretion with respect to that portion of the net 
proceeds. See "Use of Proceeds." 

   22. Need for Additional Financing. Although the Company anticipates that 
the net proceeds of the Offering, together with cash flow from operations, 
will be sufficient to satisfy the Company's anticipated cash requirements for 
the 12 months following the Effective Date, there can be no assurance that 
the Company will not require additional financing at an earlier date. This 
will depend upon the Company's ability to generate sufficient sales of its 
products and the timing of required expenditures. If the Company is required 
to obtain financing in the future, there can be no assurance that such 
financing will be available on terms acceptable to the Company, if at all. 
See "Management's Discussion and Analysis of Financial Condition and Results 
of Operations -- Liquidity and Capital Resources." 

   23. Limitation on Director Liability. The Company's certificate of 
incorporation provides that a director of the Company shall not be personally 
liable to the Company or its stockholders for monetary damages for breach of 
fiduciary duty as a director, with certain exceptions under Delaware law. 
This may discourage stockholders from bringing suit against a director for 
breach of fiduciary duty and may reduce the likelihood of derivative 
litigation brought by stockholders on behalf of the Company against a 
director. In addition, the Company's certificate of incorporation provides 
for mandatory indemnification of directors and officers. See "Management -- 
Indemnification of Officers and Directors and Limitation on Directors' 
Liability." 

   24. Absence of Dividends on Common Stock. Since inception, the Company has 
not paid any cash dividends on its Common Stock and it does not anticipate 
paying such dividends in the foreseeable future. The payment of dividends by 
the Company is within the discretion of its Board of Directors and depends 
upon the Company's earnings, capital requirements, financial condition and 
other factors deemed relevant by the Board. The Company intends to retain 
earnings, if any, to finance its operations. See "Dividends." 

   25. Dilution. Purchasers of Common Stock in the Offering will suffer 
immediate dilution of $2.58 per share (or approximately 74%) in the net 
tangible book value of their investment from the initial public offering 
price of $3.50 per share of Common Stock. See "Dilution." 

   26. Consideration Paid By Existing Stockholders. Officers, directors and 
other existing stockholders acquired their shares of Common Stock at an 
average per share price of $0.58 per share, substantially less than the 
initial public offering price of $3.50 per share. Accordingly, investors in 
the Offering will bear a disproportionate share of the risk of an investment 
in the Company. See "Dilution." 

   27. Authorization and Discretionary Issuance of Preferred Stock.  The 
Company's Certificate of Incorporation authorizes the issuance of 5,000,000 
shares of "blank check" preferred stock with such designations, rights and 
preferences as may be determined from time to time by the Board of Directors. 
Accordingly, the Board of Directors is empowered, without stockholder 
approval, to issue preferred stock with dividend, liquidation, conversion, 
voting or other rights which could decrease the amount of earnings and assets 
available for distribution to holders of Common Stock and adversely affect 
the relative voting power or other rights of the holders of the Company's 
Common Stock. In the event of issuance, the preferred stock could be used, 
under certain circumstances, as a method of discouraging, delaying or 
preventing a change in control of the Company. Except for 2,500 shares of 
Series A Preferred Stock authorized for issuance in exchange for the 
cancellation of amounts due to Joel Schoenfeld, Flora Schoenfeld and two 
corporation's affiliated with Mr. Schoenfeld (collectively, the "Schoenfeld 
Parties"), and Dr. Alan Gold, and payment of dividends thereon in additional 
shares of Series A Preferred Stock, the Company has no present intention to 
issue any shares of its preferred stock. However, there can be no assurance 
that the Company will not issue shares of preferred stock in the future. The 
Company has agreed with the Underwriters that, except for issuances disclosed 
in or contemplated by this Prospectus, it will not issue any securities, 
including but no limited to any shares of preferred stock, for a period of 24 
months following the Effective Date, without the prior written consent of the 
Representative. See "Certain Transactions" and "Description of Securities -- 
Preferred Stock."

   28. No Assurance of Public Market; Determination of Public Offering Price; 
Possible Volatility of Market Price for the Common Stock and Warrants. Prior 
to the Offering, there has been no public trading market for the Common Stock 
or the Warrants. Consequently, the initial public offering price of the 
Common Stock and Warrants and the exercise price and other terms of the 
Warrants were determined through negotiations between the Company and the 
Representative and bear no relationship whatsoever to the Company's assets, 
book value per share, results of operations or other generally accepted 
criteria of value. The offering prices of the Common Stock and Warrants, as 
well as the exercise price of the Warrants, should not be construed as 
indicative of their value. There can be no assurance that an active trading 
market for the Common Stock and Warrants will develop after the Offering or 
that, if developed, it will be sustained. As a result, investors will be 
exposed to a risk of a decline in the market prices of the Common Stock and 
Warrants after the Offering. The market prices of the Common Stock and 
Warrants following the Offering may be highly volatile as has been the case 
with the securities of many emerging companies. The Company's operating 
results and various factors affecting the medical device industry may impact 
the market price of the Company's securities to a significant degree. In 
addition, in recent years the stock market has experienced a high level of 
price and volume volatility, and market prices for the securities of many 
companies have experienced wide price fluctuations not necessarily related to 
the operating performance of such companies. There can be no assurance that 
the market price of the Common Stock and the Warrants will not experience 
significant fluctuations or decline below the initial public offering price. 

   29. Limited Underwriting Experience of Representative. The Representative 
has served as the sole or managing underwriter of only three firm commitment 
public offerings and participated in two other underwritten public offerings 
as a member of the underwriting syndicate. Since the Representative's 
experience in underwriting firm commitment public offerings is limited, there 
can be no assurance that its lack of experience may not adversely affect the 
public offering of the Company's securities and the subsequent development, 
if any, of a trading market for the Company's securities. See "Risk Factors 
- -- Representative's Influence on the Market; Possible Limitations on Market 
Making Activities." 

   30. Representative's Influence on the Market; Possible Limitations on 
Market Making Activities. A significant number of shares of Common Stock and 
Warrants may be sold to customers of the Representative. Such customers 
subsequently may engage in transactions for the sale or purchase of such 
securities through or with the Representative. The Representative has 
indicated that it intends to act as a market-maker and otherwise effect 
transactions in the Common Stock and Warrants. To the extent the 
Representative acts as a market-maker in the Common Stock and Warrants, it 
may exert a dominating influence in the markets for those securities. The 
prices and liquidity of the shares of Common Stock and Warrants may be 
significantly affected to the extent, if any, that the Representative 
participates in such markets. Furthermore, the Representative may discontinue 
such activities at any time or from time to time. The Representative also has 
the right to act as the Company's exclusive agent in connection with any 
future solicitation of holders of Warrants to exercise their Warrants. 
Applicable rules of the Securities and Exchange Commission prohibit the 
Representative and any other soliciting broker-dealers from engaging in any 
market making activities or solicited brokerage activities with regard to the 
Common Stock and Warrants for a period of up to five business days prior to 
the solicitation of the exercise of any Warrants until the later of the 
termination of such solicitation activity or the termination of any right the 
Representative may have to receive a fee for the solicitation of the 
Warrants. As a result, the Representative and such soliciting broker-dealers 
may be unable to continue to make a market for the Common Stock and the 
Warrants during certain periods while the Warrants are exercisable. Such a 
limitation, while in effect, could impair the liquidity and market price of 
the Common Stock and the Warrants. See "Underwriting." 

   31. Representative's Potential Influence on the Company. The Company has 
agreed that for three years from the Effective Date, the Representative may 
designate one person for election to the Company's Board of Directors and 
that the Company will reasonably cooperate with the Representative in respect 
of such designation. The election of such designee, if any, may enable the 
Representative to exert influence on the Company. The Representative has not 
designated any individual for election to the Company's Board of Directors. 
See "Underwriting." 

   32. Possible Delisting. Application has been made for the inclusion of the 
shares of Common Stock and Warrants on The Nasdaq SmallCap Market. There can 
be no assurance that the Common Stock and Warrants 
    

                                      16 
<PAGE>

will qualify for quotation on The Nasdaq SmallCap Market. Furthermore, 
assuming that the Common Stock and Warrants are approved for quotation on The 
Nasdaq SmallCap Market, there can be no assurance that the Company will be 
able to satisfy specified financial tests and market related criteria 
required for continued quotation thereon following the Offering. If the 
Company is unable to satisfy The Nasdaq SmallCap maintenance criteria in the 
future, the Common Stock and Warrants may be delisted from trading on The 
Nasdaq SmallCap Market, and if delisted, trading, if any, would thereafter be 
conducted in the over-the-counter market in the so-called "pink sheets" or 
the "Electronic Bulletin Board" of the National Association of Securities 
Dealers, Inc. ("NASD"), and, consequently, an investor could find it more 
difficult to dispose of, or to obtain accurate quotations as to the price of, 
the Company's securities. 

   The Nasdaq Stock Market has recently proposed amendments to its rules 
increasing eligibility and maintenance criteria for The Nasdaq SmallCap 
Market. Existing eligibility criteria for inclusion on The Nasdaq SmallCap 
require, among other things, that an issuer have total assets of $4 million 
and total equity of $2 million, and that the security to be listed has a 
minimum bid price of $3.00 per share. The proposed amendment would require, 
among other things, that an issuer have net tangible assets (i.e., total 
assets less total liabilities and intangible assets) of $4 million (or 
alternatively, net income in two of the most recent three fiscal years of at 
least $750,000, or a market capitalization of $50 million) and that the 
security to be listed has a minimum bid price of $4.00 per share. Existing 
maintenance criteria require, among other things, that an issuer have total 
assets of $2 million and total equity of $1 million and that the listed 
security has a minimum bid price of $1.00. The amendment would require, among 
other things, that an issuer have net tangible assets of $2 million (or 
alternatively net income of $500,000 in two of the most recent three fiscal 
years, or a market capitalization of $35 million) and that the listed 
security has a minimum bid price of $1.00. Adoption of the proposed 
amendments, which are not expected to become effective until after the 
completion of the Offering, would further increase the risk of having the 
Company's Common Stock and Warrants delisted. 

   
   33. Risk of Low-Priced Securities. The regulations of the Securities and 
Exchange Commission promulgated under the Exchange Act require additional 
disclosure relating to the market for penny stocks in connection with trades 
in any stock defined as a penny stock. Commission regulations generally 
define a penny stock to be an equity security that has a market price of less 
than $5.00 per share, subject to certain exceptions. Unless an exception is 
available, those regulations require the delivery, prior to any transaction 
involving a penny stock, of a disclosure schedule explaining the penny stock 
market and the risks associated therewith and impose various sales practice 
requirements on broker-dealers who sell penny stocks to persons other than 
established customers and accredited investors (generally institutions). In 
addition, the broker-dealer must provide the customer with current bid and 
offer quotations for the penny stock, the compensation of the broker-dealer 
and its salesperson in the transaction, and monthly account statements 
showing the market value of each penny stock held in the customer's account. 
Moreover, broker-dealers who recommend such securities to persons other than 
established customers and accredited investors must make a special written 
suitability determination for the purchaser and receive the purchaser's 
written agreement to a transaction prior to sale. If the Company's securities 
become subject to the regulations applicable to penny stocks, the market 
liquidity for the Company's securities could be severely affected. In such an 
event, the regulations on penny stocks could limit the ability of broker- 
dealers to sell the Company's securities and thus the ability of purchasers 
of the Company's securities to sell their securities in the secondary market. 

   34. Shares Eligible for Future Sale. No assurance can be given as to the 
effect, if any, that future sales of Common Stock, or the availability of 
shares of Common Stock for future sales, will have on the market price of the 
Common Stock from time to time. Sales of substantial amounts of Common Stock 
(including shares issued upon the exercise of warrants or stock options), or 
the possibility of such sales, could adversely affect the market price of the 
Common Stock and Warrants and also impair the Company's ability to raise 
capital through an offering of its equity securities in the future. Upon 
completion of the Offering, the Company will have 2,621,054 shares of Common 
Stock outstanding, of which only the 1,500,000 shares of Common Stock offered 
hereby will be transferable without restriction under the Securities Act. The 
remaining 1,121,054 shares, issued in private transactions, will be 
"restricted securities" (as defined in Rule 144 promulgated under the 
Securities Act) which may be publicly sold only if registered under the 
Securities Act or if sold in accordance with an applicable exemption from 
registration, such as Rule 144. In general, under Rule 144, as currently in 
effect, subject to the satisfaction of certain other conditions, a person, 
including an affiliate of the Company, who has beneficially 
    

                                      17 
<PAGE>

   
owned restricted securities for at least two years (which holding period will 
be reduced to one year under a recent amendment to Rule 144 that becomes 
effective April 29, 1997), is entitled to sell (together with any person with 
whom such individual is required to aggregate sales), within any three-month 
period, a number of shares that does not exceed the greater of 1% of the 
total number of outstanding shares of the same class or, if the Common Stock 
is quoted on The Nasdaq Stock Market or a national securities exchange, the 
average weekly trading volume during the four calendar weeks preceding the 
sale. A person who has not been an affiliate of the Company for at least 
three months and who has beneficially owned restricted securities for at 
least three years (which holding period will be reduced to two years under a 
recent amendment to Rule 144 that becomes effective April 29, 1997) is 
entitled to sell such restricted shares under Rule 144 without regard to any 
of the limitations described above. Officers, directors and other 
securityholders of the Company owning and/or having rights to acquire in the 
aggregate 3,676,726 shares of Common Stock, have entered into agreements not 
to sell or otherwise dispose of any securities of the Company, including 
Common Stock, for a period of 24 months following the Effective Date (the 
"Lock-Up Agreements"), without the prior written consent of the 
Representative, which may be granted or withheld in the sole and absolute 
discretion of the Representative; provided, however, that if during such 24 
month period, the Company's shares of Common Stock are subject to a tender 
offer and holders of the Company's Common Stock (other than the current 
stockholders) agree to tender a majority of the outstanding shares of Common 
Stock to the offeror, then the Representative shall release all stockholders 
subject to the Lock-Up Agreement from the restrictions imposed thereby solely 
for the purposes of tendering their shares of Common Stock to the offeror 
pursuant to the terms of the tender offer. The Company has registered for 
resale pursuant to the Selling Securityholder Prospectus (i) warrants to 
purchase 2,500,000 shares of Common Stock (having terms identical to the 
Warrants offered hereby) and the shares of Common Stock issuable upon 
exercise thereof and (ii) 33,436 shares of Common Stock issuable upon 
exercise of options, subject to the Lock-Up Agreements. Following expiration 
of the term of the Lock-Up Agreements, or the earlier release of the 
restrictions contained therein, 1,121,054 shares will become eligible for 
resale pursuant to Rule 144, subject to the volume limitations and compliance 
with the other provisions of Rule 144, assuming the sale of the shares 
pursuant to the Selling Securityholder Prospectus. Furthermore, the holders 
of the Underwriters' Warrants (including the securities issuable upon 
exercise thereof) have demand and piggyback registration rights with respect 
to the shares of Common Stock and Warrants issuable upon exercise of the 
Underwriters' Warrants. See "Description of Securities -- Registration 
Rights," "Description of Securities -- Shares Eligible for Future Sale," 
"Certain Transactions," "Underwriting" and "Selling Securityholder Offering." 

   35. Effect of Issuance of Common Stock Upon Exercise of Warrants and 
Options; Possible Issuance of Additional Options. Immediately after the 
Offering, assuming the Over-Allotment Option is not exercised, the Company 
will have an aggregate of approximately 12,047,413 shares of Common Stock 
authorized but unissued and not reserved for specific purposes and an 
additional 10,331,533 shares of Common Stock unissued but reserved for 
issuance (i) upon exercise of options (including options which may be granted 
in the future pursuant to the Company's stock option plan), (ii) upon 
exercise of warrants (including the Warrants), (iii) upon exercise of the 
Underwriters' Warrants (and the Warrants included therein), (iv) upon 
conversion of a 12 1/2 % demand promissory note in the principal amount of 
$125,000, and (v) upon conversion of the Company's Series A Preferred Stock. 
All of such shares may be issued without any action or approval by the 
Company's stockholders. Although there are no present plans, agreements, 
commitments or undertakings with respect to the issuance of additional shares 
or securities convertible into any such shares by the Company, any shares of 
Common Stock issued would further dilute the percentage ownership of the 
Company held by the public stockholders. The Company has agreed with the 
Underwriters that, except for the issuances disclosed in or contemplated by 
this Prospectus, it will not issue any securities, including but not limited 
to any shares of Common Stock, for a period of 24 months following the 
Effective Date, without the prior written consent of the Representative. See 
"Underwriting." 
    

   The exercise of warrants or options and the sale of the underlying shares 
of Common Stock (or even the potential of such exercise or sale) may have a 
depressive effect on the market price of the Common Stock and the Warrants. 
Moreover, the terms upon which the Company will be able to obtain additional 
equity capital may be adversely affected since the holders of outstanding 
warrants and options can be expected to exercise them, to the extent they are 
able, at a time when the Company would, in all likelihood, be able to obtain 
any needed capital on terms more favorable to the Company than those provided 
in the warrants and options. See "Management -- Stock Option Plan," 
"Description of Securities" and "Underwriting." 

                                      18 
<PAGE>

   
   36. Adverse Effect of Redemption of Warrants. Under certain conditions, 
the Warrants may be redeemed by the Company with the prior written consent of 
the Representative, at a redemption price of $.05 per Warrant upon not less 
than 30 days prior written notice to the holders of such Warrants, provided 
the closing bid price of the Common Stock has been at least $8.00 for 20 
consecutive trading days ending on the third day prior to the date the notice 
of redemption is given. The Warrants will be exercisable until the close of 
business on the day immediately preceding the date fixed for redemption. The 
redemption of the Warrants could force the holders (i) to exercise the 
Warrants and pay the exercise price at a time when it may be disadvantageous 
for the holders to do so, (ii) to sell the Warrants at the then current 
market price when they might otherwise wish to hold the Warrants or (iii) to 
accept the redemption price, which is likely to be substantially less than 
the market value of the Warrants at the time of redemption. See "Description 
of Securities -- Warrants." 

   37. Need for Future Registration of Warrants; State Blue Sky Registration; 
Exercise of Warrants. The Warrants will trade separately upon the completion 
of the Offering. Although the Warrants will not knowingly be sold to 
purchasers in jurisdictions in which the Warrants are not registered or 
otherwise qualified for sale, purchasers may buy Warrants in the after-market 
or may move to jurisdictions in which the Warrants and the shares of Common 
Stock underlying the Warrants are not so registered or qualified. In this 
event, the Company would be unable to issue shares of Common Stock to those 
persons desiring to exercise their Warrants unless and until the Warrants and 
the underlying shares of Common Stock are qualified for sale in jurisdictions 
in which such purchasers reside, or an exemption from such qualification 
exists in such jurisdictions. There can be no assurance that the Company will 
be able to effect any required qualification. 
    

   The Warrants will not be exercisable unless the Company maintains a 
current Registration Statement on file with the Commission through 
post-effective amendments to the Registration Statement containing the 
Prospectus. Although the Company has agreed to file appropriate 
post-effective amendments to the Registration Statement containing the 
Prospectus and to maintain a current Prospectus with respect to the Warrants, 
there can be no assurance that the Company will file post-effective 
amendments necessary to maintain a current Prospectus or that the Warrants 
will continue to be so registered. See "Description of Securities -- 
Warrants."

                               USE OF PROCEEDS 

   The net proceeds to the Company from the sale of the shares of Common 
Stock and Warrants offered hereby, after deducting underwriting discounts and 
other expenses of the Offering, are estimated to be $4,284,250 ($4,998,738 if 
the Over-Allotment Option is exercised in full). The Company expects to use 
the net proceeds of the Offering as follows:

(1)  Includes production equipment (mold and inserts, assembly machine, clip
     attachment line, packaging machine and automatic loader), as well as
     furniture, fixtures and equipment for a warehouse facility. Except for the
     clip attachment line, which will be used by INSERPOR at its production
     facility in Portugal to assemble the Company's syringes, all of the
     production equipment will be used by Harmac at its production facility in
     Buffalo, New York to assemble the Company's syringes. The Company will
     retain ownership of the production equipment and neither INSERPOR nor
     Harmac will acquire any interest therein, other than the right to use the
     equipment in connection with the assembly of the Company's syringes.

(2)  Includes the cost of hiring and retaining a marketing director and expenses
     relating to market research, promotion (including advertising) and public
     relations.

(3)  Includes the cost of retaining a research and development officer and the
     cost of developing prototype parts.

(4)  The Bridge Notes, issued in connection with the Bridge Financing in the
     fourth quarter of 1996, bear interest at 8% per annum and are payable upon
     the earlier of November 27, 1997 or the consummation of an initial public
     offering or private placement of the Company's debt and/or equity
     securities resulting in gross proceeds to the Company of at least
     $5,000,000. The net proceeds of the Bridge Financing (approximately
     $820,000) were used in part to purchase machinery ($235,000) and for sales
     and marketing ($235,000). The Company used the remaining net proceeds as
     working capital.

(5)  Includes working capital to support inventory and accounts receivable, and
     management salaries. See "Management -- Employment Agreements.

    

   Additional proceeds from the exercise of the Over-Allotment Option and the 
Warrants will be added to the Company's working capital and be available for 
general corporate purposes. Pending application, the Company will invest the 
net proceeds of the Offering in United States government securities, short 
term certificates of deposit, money market securities, investment grade 
commercial paper or other short-term interest-bearing investment-grade 
securities. 

   
   The Company has not determined the specific allocation of the net proceeds 
within each of the various uses described above. Specific allocations of such 
net proceeds will ultimately depend on the development of the Company's 
products and the related technology and commercial acceptance of its 
products. The Company anticipates, based on currently proposed plans and 
assumptions relating to its operations, that the net proceeds of the Offering 
will be sufficient to satisfy the Company's anticipated cash requirements for 
the 12 months following the Effective Date.

                                   DILUTION 

   
   At December 31, 1996, the net tangible book value (deficit) of the Company 
was ($2,090,430), or approximately ($1.93) per share of Common Stock, as 
adjusted for the cancellation of approximately $650,000 of accrued expenses 
due to certain stockholders and affiliates of the Company in exchange for 650 
shares of Series A Preferred Stock subsequent to December 31, 1996. The net 
tangible book value of the Company is the tangible assets (total assets less 
intangible assets, deferred financing and offering costs) less total 
liabilities. Dilution per share represents the difference between the amount 
paid per share of Common Stock by investors in the Offering, attributing no 
value to the Warrants. 

   After giving effect to (i) the issuance and sale of 1,500,000 shares of 
Common Stock and 2,250,000 Warrants in the Offering, (ii) the cancellation of 
amounts payable to a director of the Company ($120,390 assuming the Closing 
occurs on March 31, 1997) concurrently with the Closing in exchange for the 
issuance of approximately 34,397 shares of Common Stock, (iii) the 
cancellation of amounts payable to an officer of the Company ($15,295) 
concurrently with the Closing in exchange for the issuance of 4,370 shares of 
Common Stock, but without taking into account any other changes in net 
tangible book value subsequent to December 31, 1996, other than those 
described in the immediately preceding paragraph, the pro forma net tangible 
book value of the Company as of December 31, 1996 would have been $2,422,005, 
or $0.92 per share. This represents an increase in net tangible book value 
per share of $2.85 to the Company's existing stockholders and an immediate 
dilution of $2.58 per share (or 73.7% of the offering price) to new 
stockholders purchasing shares of Common Stock in the Offering. The following 
table illustrates this dilution on a per share basis:

   The payment of dividends by the Company is within the discretion of its 
Board of Directors and depends in part upon the Company's earnings, capital 
requirements and financial condition. Since its inception, the Company has 
not paid any cash dividends on its Common Stock and does not anticipate 
paying such dividends in the foreseeable future. The Company intends to 
retain earnings, if any, to finance its operations.

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

   The following discussion and analysis should be read in conjunction with 
the consolidated financial statements, including the notes thereto, appearing 
elsewhere in this Prospectus. 

   
   Since inception, the Company's operations have consisted primarily of the 
design, development, testing and evaluation of its locking clip syringes, 
production processes, and production equipment, which include molds, inserts 
and assembly machine. As of December 31, 1996, UNIVEC had no commercial sales 
of its locking clip syringes. In the fourth quarter of 1995 and in 1996, the 
Company sold lancets manufactured by Sherwood to one distributor, which 
resold the lancets to retailers in Canada and the United States. The terms of 
purchase and resale of these lancets was negotiated by the Company 
independently with Sherwood and the distributor. The Company does not have a 
distribution agreement or similar arrangement with Sherwood for lancets. In 
the first two months of 1997, the Company sold approximately 1,777,000 
syringes produced by INSERPOR, including over 900,000 sold to WHO. 

   In the second quarter of 1996, the Company entered into an agreement to 
buy syringe components from Sherwood (the "Sherwood Supply Agreement"). In 
connection with the Sherwood Supply Agreement, Sherwood sold all of its 
right, title and interest in and to the production mold for the plunger, 
including the mold inserts and insert base (together, the "Plunger Mold") to 
the Company in consideration for an option to enter into a non-exclusive 
license to manufacturer and sell the Company's locking clip syringes in the 
United States. The Company also entered into a lease agreement with Sherwood 
pursuant to which it leased back the Plunger Mold to Sherwood (the "Equipment 
Lease") for a period of six years for use in the manufacture and production 
of the plungers as part of the assembly of non-aspirating syringes using the 
Company's proprietary design specifications. Sherwood is required to make 
aggregate rental payments of $1,946,016 in 36 equal consecutive monthly 
installments of $54,056, over the first three years of the term of the 
Equipment Lease. In consideration for said lease payments, the Company agreed 
to pay Sherwood 14.925% of the cumulative invoiced amount of components in 
excess of $3,350,000 up to a maximum invoiced amount of $6,700,000 (or a 
maximum of $500,000). In addition, certain stockholders of the Company agreed 
to pay Sherwood up to $1 million (less 14.925% of each dollar paid by the 
Company under the Sherwood Supply Agreement) in the event the Company fails 
to pay a cumulative invoiced amount of $6.7 million over the first three 
years of the Sherwood Supply Agreement. In July 1996, the Company sold the 
Plunger Mold, subject to the Equipment Lease, together with the Company's 
right to the payments under the Equipment Lease, to a financial institution 
for net cash consideration of $1,600,000 ($1,837,904 less expenses of 
approximately $238,000). In connection with such sale, the financial 
institution agreed to sell the Plunger Mold back to the Company for a nominal 
amount upon expiration of the term of the Equipment Lease. The Company has 
deferred recognition of approximately $1,684,000, which equals the net 
proceeds from the lease payments received from Sherwood and the 34 payments 
sold to a financial institution. Unearned income in connection with these 
agreements will be recognized upon the sale of the Company's locking clip 
syringes which include components supplied by Sherwood under the Sherwood 
Supply Agreement. See "Business -- Suppliers" and "Certain Transactions." 

   In the United States, the Company's products are subject to regulation by 
the FDA. In December 1994, the Company was granted 510(k) clearance by the 
FDA for its locking clip syringe. In addition, the FDA requires the Company 
to be in compliance with GMP requirements and to demonstrate that its devices 
are safe and effective. At any time, the FDA can audit the Company's 
compliance with GMP requirements and can require the Company to demonstrate 
that its products are safe and effective. See "Risk Factors -- Government 
Regulation." 

   The Company has incurred net losses for each period since its inception. 
The Company expects operating losses to continue until such time, if ever, as 
the Company can sell significant units of its locking clip syringes, and it 
can manufacture syringes at costs sufficiently lower than selling prices so 
that gross profits cover overhead expenses. See "Risk Factors -- Continuing 
Losses; Accumulated Deficit; Working Capital Deficit," " Risk Factors -- 
Limited Operating History" and "Risk Factors -- Product Acceptance; Demand 
for Locking Clip Syringes."

RESULTS OF OPERATIONS 

   
Fiscal Years Ended December 31, 1996 and 1995 

   Sales. Sales for the fiscal year ended December 31, 1996 ("Fiscal 1996") 
decreased by approximately $646,000 as compared to the fiscal year ended 
December 31, 1995 ("Fiscal 1995") as result of fewer resales of medical 
devices. However, gross profits for Fiscal 1996 increased by approximately 
$24,000 as compared to Fiscal 1995 as result of higher margins. During Fiscal 
1996, the Company had no sales of its locking clip syringes, but it resold 
lancets manufactured by Sherwood to one distributor, which resold the lancets 
to retailers in Canada and the United States. During Fiscal 1995, the Company 
had no sales of its locking clip syringes, but it resold lancets manufactured 
by Sherwood and syringes manufactured by INSERPOR, which did not utilize the 
Company's locking clip. 

   Cost of Sales. Cost of sales for Fiscal 1996 decreased by approximately 
$670,000 as compared to Fiscal 1995 as result of fewer resales of medical 
devices. The cost of sales for Fiscal 1996 includes the purchase of lancets 
from Sherwood and freight charges. The cost of sales for Fiscal 1995 includes 
the purchase of lancets from Sherwood, the purchase of syringes from 
INSERPOR, and freight charges. 

   Marketing. Marketing expenses for Fiscal 1996 (approximately $190,000) 
increased by approximately $75,000, or 65%, as compared to Fiscal 1995 
(approximately $115,000). This increase is primarily due to increased 
expenditures for brochures and package design and, to a lesser extent, 
increased expenditures for promotion. 

   Product Development. Product development expenses for Fiscal 1996 
(approximately $219,000) decreased by approximately $80,000, or 27%, as 
compared to Fiscal 1995 (approximately $299,000). This decrease is primarily 
due to a reduction in legal fees for patents. 

   General and Administrative. General and administrative expenses for Fiscal 
1996 (approximately $753,000) increased by approximately $320,000, or 74%, as 
compared to Fiscal 1995 (approximately $433,000). This increase is 
principally attributable to an increase in legal fees for the Sherwood Supply 
Agreement, financing transactions and general corporate matters, and to a 
lesser extent, higher payroll, including the salary of a full-time chief 
financial officer for the entire Fiscal 1996 as compared to only four months 
of Fiscal 1995. 

   Interest Expense. Interest expense for Fiscal 1996 (approximately 
$261,000) increased by approximately $108,000, or 71%, as compared to Fiscal 
1995 (approximately $153,000), due to increased notes payable weighted for 
the period of time the indebtedness was outstanding. 

   Royalty Expense. Royalty expense for Fiscal 1996 (approximately $133,000) 
increased by approximately $98,000, or 280%, as compared to the 1995 interim 
(approximately $35,000) as result of certain payments made to secure licensed 
rights for patents covering two locking devices for hypodermic syringes 
utilizing apparatuses or methods different than those covered by the 
Company's locking clip patents. During Fiscal 1995, the Company made payments 
to secure licensed rights relating to another patent. The Company licensed 
these patents to develop a 3cc locking syringe. 

   Net Loss. The net loss for Fiscal 1996 (approximately $1,441,000) 
increased by approximately $495,000, or 52%, as compared to the net loss for 
Fiscal 1995 (approximately $946,000), due to higher marketing, general and 
administrative, royalty and interest expenses. This increase was offset 
partially by higher gross profits and lower product development expenses. 
Because the Company elected to be treated as an S corporation for 1995, the 
net loss for Fiscal 1995 and Fiscal 1996 was passed through to its 
stockholders. The accumulated deficit of approximately $1,866,000 at the end 
of Fiscal 1994, when the Company was treated as a C corporation, is available 
to offset future net income after the Company's tax status returns to a C 
corporation in 1997 as a result of the Offering. 
    

LIQUIDITY AND CAPITAL RESOURCES 

   
   In Fiscal 1995 and Fiscal 1996, the Company's expenses have exceeded gross 
profits from resales of hypodermic devices. Operations have been funded 
primarily from (a) the receipt of two payments under the Sher- 
    

                                      26 
<PAGE>

   
wood Lease Agreement and the assignment of the remaining 34 payments 
(approximately $1,684,000), and (b) net proceeds of approximately $820,000 
from the issuance and sale of $1,000,000 principal amount of Bridge Notes and 
Bridge Warrants to purchase 2,250,000 shares of Common Stock, for a total 
purchase price of $1,000,000. See "Business -- Supplies," "Certain 
Transactions" and "Description of Securities -- Bridge Financing." 

   The Company used cash from operating activities in Fiscal 1995 and Fiscal 
1996. Net losses in each of these periods greatly affected net cash from 
operations. In Fiscal 1995, the Company used cash from operations of 
approximately ($530,000): (a) the increases to cash from operating activities 
were mostly from accounts payable and accrued expenses of approximately 
$426,000 (including $171,000 payable to two officers) and issuance of Common 
Stock for services of $35,000, and (b) the decreases to cash from operating 
activities were primarily from a net loss of approximately ($946,000) and 
accounts receivable of approximately ($63,000). In Fiscal 1996, the Company 
used cash from operations of approximately ($1,217,000): (a) the increases to 
cash from operating activities were mostly from accounts payable and accrued 
expenses of approximately $456,000 (including $73,000 payable to two 
officers) and depreciation, amortization and non cash charges of 
approximately $145,000 and (b) the decreases to cash from operating 
activities were primarily from a net loss of approximately ($1,441,000), 
accounts receivable of approximately ($86,000), and inventory of syringe 
components available for production of approximately ($239,000). 

   The Company's investing activities have consisted primarily of 
expenditures for production equipment, which totaled approximately $374,000 
and $489,000 in Fiscal 1995 and Fiscal 1996, respectively. The expenditures 
for Fiscal 1995 and Fiscal 1996 were for assembly equipment and tools and 
dies to produce the Company's proprietary clip. As of December 31, 1996, the 
Company is committed to pay (approximately $45,000) for production equipment 
for its first syringe line located at Harmac in Buffalo, New York. The 
Company intends to use a portion of the net proceeds of the Offering to 
purchase a clip-attachment line for INSERPOR in Portugal, a second production 
line for Harmac in Buffalo, New York, and furniture, fixtures and equipment 
for a warehouse facility (approximately $1,442,000). 

   The Company provided cash from financing activities in Fiscal 1995 and 
Fiscal 1996. In Fiscal 1995, cash from financing activities was approximately 
$1,011,000, provided primarily from the issuance of promissory notes for 
$665,000 and the sale of equity securities to a director for $300,000. In 
Fiscal 1996, cash provided from financing activities was approximately 
$1,985,000: (a) increases to cash were comprised primarily of approximately 
$1,684,000 contributed by unearned income from supply and licensing 
agreements with Sherwood, $1,000,000 provided through the sale of Bridge 
Notes as part of the Bridge Financing and $397,000 from the sale of 
promissory notes, and (b) decreases to cash from financing activities were 
primarily from payments of promissory notes ($937,000), deferred financing 
costs ($179,500) and deferred offering costs ($92,500). 

   The Company expects to incur additional operating losses and cash 
requirements at least through 1997. These losses will continue until such 
time as the Company builds up sufficient sales and margins to offset 
expenses, which include continuing product and machine development for new 
syringe products. The timing and amounts of these cash requirements will 
depend on many factors, some of which are beyond the Company's control, such 
as the progress of the Company's product development projects, improvements 
to existing manufacturing processes, and sales of Company products at prices 
sufficient to cover expenses. The Company expects that the net proceeds of 
the Offering, together with cash flow from operations, will be sufficient to 
satisfy its anticipated cash requirements for the 12 months following the 
Effective Date. 

   The Company's consolidated financial statements for the year ended 
December 31, 1996, indicate that there is substantial doubt about the 
Company's ability to continue as a going concern due to the Company's need to 
attain profitable operations and to obtain adequate long-term financing. See 
Note 2 of Notes to the Company's consolidated financial statements appearing 
elsewhere herein.

                                   BUSINESS 

   
   UNIVEC develops and markets safety hypodermic syringes designed to protect 
the healthcare worker and patient against cross-infection. The Company also 
sells and intends to develop other hypodermic devices. In January 1997, the 
Company commenced production and sales of its 1cc locking clip syringes, 
which are designed to make accidental or deliberate reuse difficult. The 
accidental or deliberate reuse of syringes is a frequent cause of the spread 
of the human immunodeficiency and hepatitis viruses, as well as other 
blood-borne pathogens. The Company has received 510(k) clearance from the 
U.S. Food and Drug Administration to market its locking clip syringes in the 
United States. 

   The Company offers aspirating and non-aspirating models of its lcc locking 
clip syringes. With the aspirating syringe, the UNIVEC locking clip does not 
limit the user's ability to withdraw and depress ("to aspirate") the plunger 
until the user locks the syringe voluntarily. With the non-aspirating 
syringe, the UNIVEC locking clip limits the user's ability to aspirate the 
plunger and locks the syringe passively. 

   In addition to marketing its safety syringes, the Company resells medical 
devices of other companies (e.g., traditional disposable syringes and 
lancets, which are hypodermic devices used in conjunction with blood 
testing). To date, the Company's revenues have been derived almost 
exclusively from resales of traditional disposable devices and lancets. The 
Company seeks to resell other medical devices that promote safety and 
complement its hypodermic syringes. The Company's management expects the 
relative significance of its resale activities to decrease over time as sales 
of its safety syringes increase. 
    

PROBLEMS ASSOCIATED WITH TRADITIONAL DISPOSABLE SYRINGES 

   Accidental or deliberate reuse of disposable syringes poses a serious risk 
of transmitting HIV-AIDS, hepatitis and other blood-borne pathogens for 
patients and injection drug users. Disposable syringes are used traditionally 
in developed countries and by many relief agencies such as UNICEF and WHO. 

   Intravenous drug users, who share syringes or use syringes discarded by 
hospitals, medical clinics and laboratories, doctors or diabetic patients, 
are extremely susceptible to HIV, hepatitis and other blood-borne pathogens. 
An article in the May 1996 American Journal of Public Health for Disease 
Control written by an epidemiologist for the Center for Disease Control and 
Prevention estimates that nearly half of all new HIV infections are occurring 
in intravenous drug users ("IDUs"). The article indicates that in New York 
City the number of IDUs at risk (69,000) exceeds the number of men who have 
sex with other men at risk ("MSM"), and that the number of IDUs at risk in 
Chicago (10,500) and Detroit (3,460) is 87% and 71%, respectively, of the 
number of MSMs at risk in those cities. 

   Relief agencies, including UNICEF and WHO, administered almost a billion 
injections to women and children through immunization programs in developing 
countries in 1995. WHO reported that surveys carried out in four of its six 
regions indicated that up to a third of immunization injections were 
unsterile. But immunization injections account for less than 10% of 
injections administered within the health sector. The United Nations 
estimates that more than half of all non-immunization injections in 
developing countries are unsafe. According to an article in the New York 
Times on July 7, 1996, an estimated 21.8 million adults and children 
worldwide are infected with HIV, 90% of whom live in developing countries. 

   
   As a result of the findings in the United States and developing countries, 
public health officials have encouraged the medical industry to develop safer 
syringes to prevent the spread of blood-borne pathogens, such as HIV and 
hepatitis. In 1995, the House of Delegates -- American Medical Association 
requested "manufacturers of disposable hypodermic needles and syringes to 
adopt designs to prevent reuse and to include in the packaging clear 
directions for their correct disposal." In late 1995, UNICEF recommended "the 
use of auto- destruct syringes instead of disposable, single use syringes in 
order to avoid the hazards of unsafe injection practices." In 1996, Brazil 
adopted a law requiring disposable syringes manufactured or marketed in that 
country to include a safety device to prevent its reuse. During 1996, New 
York State enacted legislation authorizing a limited number of pilot projects 
to test the practicality and effectiveness of difficult to reuse syringes. 
Such pilot tests are to be conducted, subject to funding, in state-operated 
facilities, such as prisons, hospitals, youth detention facilities and 
development centers.

   As a result of the increase in the incidence of HIV-AIDS cases, there has 
also been considerable discussion concerning over-the-counter sales of 
non-prescription syringes and needle exchange programs, in which intravenous 
drug users exchange used syringes for sterile syringes. However, political 
and social concerns that over- the-counter sales of non-prescription syringes 
and needle exchange programs encourage and condone illegal drug use have 
limited the access of intravenous drug users to sterile syringes, including 
those with the added safety feature of a locking device to discourage reuse. 
Nevertheless, 41 states, including Connecticut, Florida, Ohio, Michigan, 
Texas and Virginia, have legalized over-the-counter sales of non-prescription 
syringes. 

   Since the introduction of the disposable syringe in the late 1940's, two 
types of features have been developed to deter the spread of blood-borne 
pathogens as a result of accidental or deliberate reuse of syringes -- 
needle-stick prevention devices and difficult to reuse syringes. 

NEEDLE STICK PREVENTION 

   
   Needle-stick prevention devices are designed to prevent accidental 
puncture injuries to health care workers and patients before, during, and 
after the use of hypodermic syringes and needles. Statistics indicate that 
less than 1% of all reported HIV infections in the United States are 
attributed to needle-stick injuries. The most prevalant needle stick 
prevention device, the extendible barrel sleeve, is not a substitute for 
features that render a syringe difficult to reuse; however, it can be 
combined with devices that make a syringe difficult to reuse. Needle-stick 
prevention methods include: 
    

   Retracting Needles, which through mechanical devices incorporated in the 
syringe, pull back the needle into the barrel after use. These devices are 
effective needle-stick prevention devices; however, operators must manually 
trigger the retraction of needles. Retracting needle devices that 
automatically trigger with a single use of the syringe can render the syringe 
design difficult to reuse. However, such devices are prone to malfunction and 
are costly to manufacture due to the complexity of the mechanics required to 
retract the needle. 

   Self-Destruct Needles, which permit the needle to be collapsed or deformed 
into a shape which cannot result in a needle-stick injury. Although 
self-destruct needle devices are mechanically simpler than retracting needle 
devices, less prone to malfunction and less costly to manufacture, such 
devices are effective only if the operator triggers the self-destruct 
feature. 

   Extendible Barrel Sleeves, which enclose the barrel of the syringe in a 
second cylinder which the operator extends before and after use to cover the 
tip of the needle. The extendible barrel sleeves often lock in their extended 
position after use. In virtually all designs, the operator of the syringe 
must manually extend the barrel sleeve after use. The sleeve does not prevent 
multiple use of the syringe before the operator encloses the barrel. However, 
extendible barrel sleeves are more cost-effective than the other alternatives 
and can be combined with a device that makes the syringe difficult to reuse. 
Becton Dickinson and Sherwood distribute traditional (1cc and 3cc) syringes 
with extendible barrel sleeves called safety syringes at a wholesale price of 
$0.18 to $0.21. 

DIFFICULT TO REUSE SYRINGES 

   To the Company's knowledge, only Bader and Becton-Dickinson distribute 
commercially, a line of difficult to reuse syringes, none of which allow for 
aspiration. Both companies developed their syringes for WHO and UNICEF 
immunization programs. 

   Relative to the Bader and Becton-Dickinson syringes, the Company believes 
that its 1cc locking clip syringes are more effective and that they are 
competitively priced. Unlike its competitors, the Company markets a locking 
clip syringe with a 1cc barrel, which is ideal for dispensing .05cc to .95cc 
dosages of medicine (e.g., allergy, immunization and insulin medicines). It 
is more difficult to deliver .05cc to .95cc dosages accurately with a syringe 
barrel that is greater than 1cc. Also unlike its competitors, the Company 
offers an aspirating syringe that healthcare workers can lock. Healthcare 
workers need aspirating syringes to mix medications in the syringe barrel and 
inject medications intravenously. Furthermore, the Company believes that 
aspirating syringes are preferred by diabetes patients and needle-exchange 
programs. 

 BADER 

   The Bader DestroJect syringe is a non-aspirating syringe developed for use 
with WHO's and UNICEF's Expanded Programme on Immunization ("EPI") 
manufactured since 1992 by Bader, a German machine tool 

                                      29 
<PAGE>

manufacturer. The DestroJect syringe, available in a 1.5 cc size, delivers a 
 .5cc dose, which is the dosage for many immunizations. To deliver a dosage 
other than .5cc, the Company believes that Bader would have to modify 
components of the DestroJect syringe. Bader can supply DestroJect syringes in 
a special dispensing carton which doubles as the disposal box for used 
syringes. The disposal box is designed to incinerate the used syringes 
reducing them to ash and an inert block of plastic and metal residue. 

 BECTON-DICKINSON 

   The Becton-Dickinson SOLOSHOT syringe is a non-aspirating syringe 
specifically designed for the EPI. Becton-Dickinson can package the SOLOSHOT 
syringes in an incineration box similar to that used by Bader. The SOLOSHOT 
syringe, available in a 3cc size, delivers a .5cc dose, which is the dosage 
for many immunizations. To deliver a dosage other than .5cc, the Company 
believes that Becton-Dickinson would have to modify components of the 
SOLOSHOT syringe. 

 UNIVEC 

   
   The Company has developed a 1cc locking clip syringe for aspirating and 
non-aspirating applications, which is ideally suited for dispensing accurate 
dosages of allergy, immunization and insulin medicines. The Company's 1cc 
locking clip syringe can deliver dosages of up to .95cc. With the aspirating 
syringe, the UNIVEC locking clip does not limit the user's ability to 
withdraw and depress ("to aspirate") the plunger until the user locks the 
syringe voluntarily. With the non-aspirating syringe, the UNIVEC locking clip 
limits the user's ability to aspirate the plunger and locks the syringe 
passively. 

   When the non-aspirating syringes is assembled, the syringe clip is placed 
on the ratcheted plunger in the position needed to limit dosage as desired. 
When the operator depresses the plunger, the clip travels down the barrel by 
an equal distance. Withdrawal of the plunger by any amount embeds the prongs 
into the barrel and the user cannot retract the plunger. 
    

   The Company's 1cc, non-aspirating, syringe was developed for the needs of 
immunization programs of EPI. Using existing components, the Company can 
limit its non-aspirating syringe to any dosage between .05cc and .95cc; 
however, the Company will have to modify its existing assembly machine to 
produce syringes with a nominal dosage less than .95cc. Recently, the EPI has 
prioritized its program for immunizing children under one for tuberculosis 
("TB"). In 1997 for TB immunization, the EPI expects to vaccinate 100 million 
children and to buy 100 million 1cc tuberculin syringes. The dosage for a TB 
vaccination is .05cc. After the Company modifies its assembly machine, it 
will be able to produce a syringe limited to a nominal dosage amount of 
 .05cc. Without modifications to components, the difficult to reuse syringes 
of Bader and Becton-Dickinson can only deliver a dosage of .5cc. For the EPI, 
the Company plans to distribute its locking clip syringes in incinerating 
cartons similar to those distributed by Bader and Becton-Dickinson. 

   
   The Company's 1cc aspirating syringe works similarly to the non-aspirating 
model, except that the clip prongs do not engage the barrel until the 
operator withdraws the plunger completely. Once the operator does so, the 
clip catches a single ratchet and travels down the barrel as the plunger is 
depressed and the operator cannot withdraw the plunger. 

   The Company's 1cc aspirating syringe was developed for healthcare workers, 
who need to mix medications in the syringe barrel and inject medicines 
intravenously. Furthermore, the Company believes that aspirating syringes are 
preferred by diabetes patients and needle-exchange programs. The Company does 
not know of any other Company that offers an aspirating syringe that can be 
locked. 

   The Company intends to develop a 3cc syringe with a luer (needleless) tip 
for use in hospitals and health clinics in 1997. In general, hospitals and 
health clinics use more 3cc syringes than 1cc syringes. Hospitals and clinics 
will have the choice of an aspirating or non-aspirating plunger and a choice 
of a syringe barrel with or without an extendible needle sheath. It is 
anticipated that production of the Company's 3cc non-aspirating syringe will 
commence by 1998. See "Risk Factors -- Ability to Develop 3cc Syringe."

SALES, MARKETING AND DISTRIBUTION 

   
   The Company's initial marketing efforts will be directed primarily to 
UNICEF, WHO and public hospitals and health facilities in New York. The 
Company also intends to market its locking clip syringes to (i) governments 
of developing countries, (ii) private hospitals and health facilities in New 
York, New Jersey and Connecticut, and (iii) retail distributors in the United 
States. The Company also plans to license its patents and proprietary 
manufacturing processes relating to its locking clip and other syringe 
designs to established medical device manufacturers. To stimulate demand for 
its safety syringes, the Company plans to initiate promotional and 
educational campaigns directed at (i) public health officers and other 
government officials responsible for public health policies, (ii) doctors and 
administrators of healthcare facilities responsible for treatment of HIV-AIDS 
patients, and (iii) liability insurance companies. The Company plans to enter 
into arrangements with independent sales agents and distributors in targeted 
markets and to hire a marketing director after the Closing. 
    

PRODUCTION 

   
   The Company's syringes will be assembled primarily by Harmac, one of the 
largest independent, privately- owned contract manufacturers of medical 
products in the United States, at its production facility in Buffalo, New 
York. The Company has entered into a manufacturing agreement with Harmac for 
the assembly of syringes, using assembly and packaging equipment supplied by 
the Company. The manufacturing agreement may be terminated by Harmac or the 
Company upon 90 days' prior written notice at the end of any calendar year. 
Sherwood will supply most of the components for the syringes assembled by 
Harmac. See "Business -- Suppliers." The Company expects that Harmac will 
commence production of the Company's syringes before the end of March 1997. 
The Company is completing applicable requirements for GMP. As soon as the 
Company satisfies GMP requirements, Harmac will begin production of the 
Company's lcc locking clip syringes. However, the Company's assembly 
equipment currently can operate at approximately 45% of its rated capacity. 
The Company expects production of its syringes at Harmac will be at or close 
to full capacity before the end of 1997. See "Risk Factors -- Dependence on 
Certain Assemblers." 

   The Company also has entered into a letter of understanding with INSERPOR, 
a Portuguese syringe manufacturer, for the assembly by INSERPOR of 
non-aspirating syringes for orders, if any, received from relief agencies 
such as WHO, using syringe components supplied by INSERPOR. In addition, 
INSERPOR will manufacture the Company's proprietary plunger for its 
aspirating syringe. INSERPOR commenced production of the Company's syringes 
in January 1997. The Company has sold approximately 1,777,000 locking clip 
syringes produced by INSERPOR, including over 900,000 to WHO. See "Risk 
Factors -- Dependence on Certain Assemblers." 
    

   Initially, the Company will produce only 1cc locking clip syringes in 
aspirating and non-aspirating models. The Company's syringes consist of a 
standard needle, barrel, rubber stopper, a ratcheted plunger designed by the 
Company, and a pronged stainless steel locking clip designed by the Company. 
The Company has obtained a patent on its stainless steel locking clip, and 
has been granted a patent for the design of a plunger which, when combined 
with the locking clip, results in a narrow barrelled difficult to reuse, 
locking syringe. The locking clip and plunger can be assembled, with minor 
modifications, into barrels manufactured by Becton Dickinson, Sherwood, 
Terumo and other syringe manufacturers. The plunger is made from plastic 
materials which are readily available from numerous sources and is currently 
manufactured by Sherwood and INSERPOR. The locking clip is made of stainless 
steel and cut and formed for the Company by Harmac. The Company owns or 
otherwise controls all production tooling used by suppliers of these 
components. 

   
   Capacity can be expanded by purchasing new production systems. The Company 
plans to use a portion of the net proceeds of the Offering to acquire 
production equipment for an additional production line to be placed at Harmac 
and a clip attachment line to be placed at INSERPOR. 
    

SUPPLIERS 

   The Company has entered into a supply agreement with Sherwood (the 
"Sherwood Supply Agreement"), pursuant to which Sherwood has agreed to supply 
the Company with at least 50 million syringe component sets per year (or 
4,166,667 per month), each set consisting of a syringe barrel, with or 
without a permanently pre- 

                                      31 
<PAGE>

   
attached needle and sheath or separate hooded needle, and a plunger tip and 
up to 8,333,333 non-aspirating syringe plungers per month, against receipt of 
purchase orders from the Company at specified prices, subject to revision for 
cost increases (not to exceed 5% during any twelve month period). In 
addition, in order for Sherwood to commit to the minimum supply requirements 
under the Sherwood Supply Agreement, the Company has agreed to pay Sherwood 
14.925% of the cumulative invoiced amount of components in excess of 
$3,350,000 up to a maximum invoiced amount of $6,700,000 (or a maximum of 
$500,000) and Joel Schoenfeld, Dr. Alan H. Gold, David Shonfeld and John 
Frank agreed, jointly and severally, to pay Sherwood up to $1,000,000 (less 
$0.14925 for each dollar paid to Sherwood under the Sherwood Supply 
Agreement) in the event the Company fails to pay a cumulative invoiced amount 
of $6,700,000 over the first three years of the Sherwood Supply Agreement. 
The Sherwood Supply Agreement is for a term of five years, but may be 
extended under certain circumstances if prior thereto Sherwood enters into a 
license agreement to manufacture and sell the Company's locking clip syringe. 
In connection with the Sherwood Supply Agreement, Sherwood sold all of its 
right, title and interest in and to the production mold for the plunger, 
including the mold inserts and insert base (together, the "Plunger Mold") to 
the Company in consideration for an option to enter into a non-exclusive 
license to manufacturer and sell the Company's locking clip syringes in the 
United States (the "License Agreement"). The Company also entered into a 
lease agreement with Sherwood pursuant to which it leased back the Plunger 
Mold to Sherwood (the "Equipment Lease") for a period of six years for use in 
the manufacture and production of the plungers as part of the assembly of 
non-aspirating syringes using the Company's proprietary design 
specifications. Sherwood is required to make aggregate rental payments of 
$1,946,016 in 36 equal consecutive monthly installments of $54,056, over the 
first three years of the term of the Equipment Lease. In July 1996, the 
Company sold the Plunger Mold, subject to the Equipment Lease, together with 
the Company's right to the payments under the Equipment Lease, to a financial 
institution for net cash consideration of $1,600,000 ($1,837,904 less 
expenses of approximately $238,000). In connection with such sale, the 
financial institution agreed to sell the Plunger Mold back to the Company for 
a nominal amount upon expiration of the term of the Equipment Lease. 

   Sherwood has the right to exercise its option to enter into the License 
Agreement at any time prior to November 30, 1999. Upon exercise of the 
option, Sherwood is required to pay the Company a royalty advance of 
$100,000, against which royalty payments may be offset. Under the License 
Agreement, Sherwood is required to pay the Company a royalty equal to 5% of 
net sales. The License Agreement may be terminated by Sherwood upon 30 days 
prior written notice. If on or before February 1, 1998, the Company receives 
a bona fide written offer from an unrelated third party to exclusively 
license the Company's patent rights for its locking clip syringe, Sherwood, 
within 30 days notice of such offer, has the right to exercise its option to 
enter into the License Agreement or to enter into an exclusive license on the 
same terms and conditions set forth in the third party offer. In the event of 
a third party offer, the Company has the right to buy-out the option rights 
granted Sherwood for $100,000. 
    

COMPETITION 

   The Company's principal competition is from traditional disposable 
syringes. Becton-Dickinson, Sherwood and Terumo control approximately 74%, 
19% and 5%, respectively, or a total of approximately 98%, of the worldwide 
syringe market, and are substantially larger, more established and have 
significantly greater financial, sales and marketing, distribution, 
engineering, research and development and other resources than the Company. 
To the Company's knowledge, only Becton-Dickinson and Bader, a German machine 
tool manufacturer, distribute commercially a line of difficult to reuse 
syringes, none of which allow for aspiration. The Bader DestroJect syringe 
and the Becton-Dickinson SOLOSHOT syringe were developed specifically for 
WHO-UNICEF-EPI immunization programs. The Bader DestroJect syringe and the 
Becton-Dickinson SOLOSHOT syringe were designed to dispense a dosage of .5cc 
only, whereas the UNIVEC 1cc locking clip syringe was designed to dispense 
dosages from .05cc to .95cc. The Company believes that UNIVEC syringes are 
more effective than competitive difficult to reuse syringes and that they are 
competitively priced. There can be no assurance that the major syringe 
manufacturers or others will not commence production of 1cc difficult to 
reuse syringes, or locking syringes which aspirate, or that the Company will 
be able to successfully compete in this market. 

PATENTS AND PROPRIETARY RIGHTS 

   The Company's policy is to seek patent protection for all developments, 
inventions and improvements that are patentable and which have potential

   In 1995, the Company was granted a United States patent for a locking clip 
device not biased against the plunger. The patent is broad enough to include 
several applications of the design covering the first series of products to 
be marketed by the Company. The Company also has filed a United States patent 
application for a plunger design which, in conjunction with its patented 
locking clip, results in a narrow barrel difficult to reuse syringe that 
allows for aspiration during use. In addition, the Company has licensed the 
rights to three other locking device patents. The Company licensed these 
patents to develop a 3cc locking syringe. The Company is obligated to make 
certain minimum annual royalty payments in respect of the licensed rights to 
these three locking device patents and, to the extent the Company's products 
utilize the claims and designs of the licensed patents, to pay royalties to 
the owner of the licensed patents ranging from 2% to 7% of net sales (or in 
the case of products produced under sublicenses granted to third parties, 10% 
to 40% of royalties received from those parties). See Notes 5 and 12 to the 
Company's consolidated financial statements appearing elsewhere herein. 
    

   The Company also has filed patent applications for its locking clip and 
aspirating plunger in certain foreign countries participating in the Patent 
Cooperation Treaty (Canada, Brazil, Mexico, certain European countries, 
Japan, South Korea, China, Russia and Australia). However, patent 
applications filed in foreign countries and patents granted in such countries 
are subject to laws, rules and procedures that differ from those in the 
United States, and accordingly, patent protection in such countries may be 
different from patent protection provided by United States laws. 
Strategically, the Company seeks manufacturing processes and agreements that 
will enable it to have reliable quality and the lowest production costs. By 
protecting its manufacturing processes, which enable the quality and cost 
competitiveness of its products, the Company believes that it can defend 
market share regardless of foreign patent protections, which are often 
unenforceable or non-existent in many world markets (e.g., China and India). 
See "Risk Factors -- Uncertainty Regards Patents and Proprietary Technology; 
Risk of Future Litigation." 

   
   The Company has patents and licenses suitable for a 3cc syringe. All of 
these inventions have U.S. patent protection, but most of these inventions 
lack foreign patent protection. However, the Company has filed for patent 
protection in certain European countries for one of its licenses, which is 
the basis for the 3cc non- aspirating syringe that the Company plans to 
develop. For the aspirating model, the choice of design will depend upon 
certain factors, including patent protection, manufacturing costs, ability to 
control quality and product features. It is anticipated that production of 
the Company's 3cc non-aspirating syringe will commence by 1998. See "Risk 
Factors -- Uncertainty Regarding Patents and Proprietary Technology; Risk of 
Future Litigation." 
    

   The future success of the Company may depend upon the strength of its 
patents. The Company believes that the scope of its patents and licenses is 
sufficient to prevent competitors from introducing devices of similar design 
to its current products and that its patents are valid and enforceable. 
However, there can be no assurance that the Company's patents will not be 
challenged, invalidated or circumvented in the future or that the rights 
granted thereunder will provide a competitive advantage. 

   The Company is not aware of any patent infringement claims against the 
Company or of any infringement of the Company's patents. Litigation to 
enforce patents issued to the Company, to protect proprietary information 
owned or licensed by the Company, or to defend the Company against claimed 
infringement of the rights of others, could be costly and could divert the 
resources of the Company from other planned activities. There can be no 
assurance that the Company would be successful in any such litigation. 

   The Company protects its proprietary information and trade secrets, 
including all aspects of its syringe assembly system, through confidentiality 
agreements with its employees and suppliers. 

   The Company has registered trademarks UNIVEC(R), and R/ Ultra(R), and the 
symbol representing no second use, (i.e., the number 2 crossed out inside of 
a circle), with the United States Patent and Trademark Office. See "Risk 
Factors -- Uncertainty Regarding Patents and Protection of Proprietary 
Technology."

GOVERNMENT REGULATION 

   
   The manufacture and distribution of medical devices are subject to 
extensive regulation by the FDA and, in some instances, by foreign and state 
governments. Pursuant to the Federal Food, Drug, and Cosmetic Act, as 
amended, and the regulations promulgated thereunder (collectively, the "FDC 
Act"), the FDA regulates the clinical testing, manufacture, labeling, sale, 
distribution and promotion of medical devices. Before a new device can be 
introduced into the market, a manufacturer must obtain FDA permission to 
market through either the 510(k) pre-market notification process or the 
costlier, lengthier and less certain pre-market approval ("PMA") application 
process. The FDA has granted the Company 510(k) clearance to market its 1cc 
locking clip syringe, which has been classified as a Class II device under 
the FDC Act, and accordingly, the Company may market and sell its 1cc locking 
clip syringe in the United States, subject to compliance with other 
applicable FDA regulatory requirements. As a Class II device, performance 
standards may be developed for the 1cc locking clip syringe which the product 
would then be required to meet. Failure to meet those standards would require 
the Company to discontinue the marketing of the product. Furthermore, 
manufacturers of medical devices are subject to recordkeeping requirements 
and required to report adverse experiences relating to the use of the device. 
Device manufacturers are also required to register their establishments and 
list their devices with the FDA and with certain state agencies and are 
subject to periodic inspections by the FDA and certain state agencies. 
    

   Medical devices are subject to strict federal regulations regarding the 
quality of manufacturing ("Good Manufacturing Practices" or "GMP"). GMP 
regulations impose certain procedural and documentation requirements upon the 
Company with respect to manufacturing and quality assurance activities. The 
FDA conducts periodic audits and surveillance of the manufacturing, 
sterilizing and packaging facilities of medical device manufacturers to 
determine compliance with GMP requirements. The failure of a medical device 
manufacturer to be able to show in the audit or post-market surveillance that 
it has adequately complied with GMP requirements can result in penalties or 
enforcement proceedings being imposed on the manufacturer. These procedures 
may include a product recall of a product or a "cease distribution" order 
which would require the manufacturer to direct its distributors and sales 
agents to stop selling products, as well as other enforcement sanctions. 
Harmac's manufacturing facilities have been certified as satisfying GMP 
requirements. Harmac's facilities will be subject to extensive audits in the 
future, pursuant to standard FDA procedure. No assurance can be given that 
when Harmac is audited that it will be found to be in compliance with GMP 
requirements, or that if it is not found in compliance, what penalties, 
enforcement procedures or compliance effort will be levied on or required of 
Harmac and/or the Company. Recently adopted GMP requirements, including those 
pertaining to design control, are likely to increase the cost of GMP 
compliance. Noncompliance with applicable requirements, including GMP 
requirements, can result in, among other things, fines, injunctions, civil 
penalties, recall or seizure of products, total or partial suspension of 
production, failure of the government to grant pre-market clearance or pre- 
market approval for devices, withdrawal of marketing approvals, and criminal 
prosecution. The FDA also has the authority to request repair, replacement or 
refund of the cost of any device manufactured or distributed by the Company. 

   
   The introduction of the Company's products in foreign markets will also 
subject the Company to foreign regulatory clearances which may impose 
additional substantive costs and burdens. The Company's products are required 
to satisfy international manufacturing standards for sale in certain foreign 
countries. Harmac expects to achieve ISO 9001 certification by the end of the 
second quarter of 1997. However, until Harmac obtains ISO 9001 certification, 
the Company will have difficulty selling to some export accounts, 
particularly in Europe. INSERPOR expects to obtain ISO 9002 in 1997. 
International sales of medical devices are subject to the regulatory 
requirements of each country. The regulatory review process varies from 
country to country. Many countries also impose product standards, packaging 
requirements, labeling requirements and import restrictions on devices. In 
addition, each country has its own tariff regulations, duties and tax 
requirements. 
    

   The approval by the FDA and foreign government authorities is 
unpredictable and uncertain, and no assurance can be given that the necessary 
approvals or clearances for the Company's products will be granted on a 
timely basis or at all. Delays in receipt of, or a failure to receive, such 
approvals or clearances, or the loss of any previously received approvals or 
clearances, could have a materially adverse effect on the business, financial 
condition and results of operations of the Company. Furthermore, approvals 
that have been or may be granted are subject to continual review, and later 
discovery of previously unknown problems may result in prod- 

                                      34 
<PAGE>

uct labeling restrictions or withdrawal of the product from the market. 
Moreover, changes in existing requirements or adoption of new requirements or 
policies could adversely affect the ability of the Company to comply with 
regulatory requirements. There can be no assurance that the Company will not 
be required to incur significant costs to comply with applicable laws and 
regulations in the future. Failure to comply with applicable laws or 
regulatory requirements could have a materially adverse effect on the 
Company's business, financial position and results of operations. 

FACILITIES 

   
   The Company occupies its executive offices in Garden City, New York 
(comprised of approximately 1,200 square feet of space) pursuant to a lease 
which expires in December 1998; however, the Company may extend the term of 
the lease for an additional two years. Rental expense for the space is 
$28,704 per annum, subject to an increase of 4% per annum in each subsequent 
year. Dr. Alan H. Gold, the President, a Director and principal stockholder 
of the Company, is the president and a stockholder of the owner of the 
premises, the Long Island Plastic Surgical Group. 
    

   The Company is seeking approximately 25,000 square feet of warehouse 
space, and intends to use a portion of the net proceeds of the Offering for 
furniture, fixtures and equipment for a warehouse facility. 

EMPLOYEES 

   
   As of March 1, 1997, the Company employed five persons, including one in 
sales and marketing, one in research and development, one in regulatory 
affairs and quality assurance and two in financial administration. The 
Company also has engaged the services of several independent contractors. 
None of the Company's employees is covered by a collective bargaining 
agreement. 
    

   The Company intends to hire a full-time marketing director upon completion 
of the Offering and to staff its warehouse facility with four people. 

LITIGATION 

   The Company is not involved in any legal proceedings.

   Joel Schoenfeld, the founder of the Company, has been Chairman of the 
Board and Chief Executive Officer of the Company since its inception in 
August 1992. Mr. Schoenfeld was the founder and President of J&B Schoenfeld, 
a global trading company whose main focus was on the import, export and 
processing of pelts and hides, specializing in trade with the USSR and 
Europe. 

   In 1988, Mr. Schoenfeld formed the American-Russian International Trading 
Company ("AMRU"), which advised on trade agreements between the USSR and 
United States. AMRU's broad base of interest and expertise enabled it to take 
on such diverse projects as a joint venture with the Soviet government and 
military known as AMRU-STAR, the representation of the Soviet Space Agency to 
Washington, D.C., the introduction of western advertising to the USSR in 
conjunction with another American company, Transportation Displays, Inc. 
("TDI"), and the construction of a studio producing children's films for 
international distribution. 

   As a result of the political changes in the former USSR, Mr. Schoenfeld 
sought to further his business strategies. In 1990, he founded Joel 
Schoenfeld & Associates in Garden City, New York. With affiliate offices in 
Moscow, San Jose, London, and Boston, the company's purpose was to originate, 
structure, capitalize, negotiate and advise on the implementation of import 
and export trade transactions, projects and programs. 

   Mr. Schoenfeld has been a commercial attache and a consultant to a number 
of foreign and multinational governments. Currently, Mr. Schoenfeld is an 
advisor to United Nations Development Programs ("UNDP"). Previously, he 
served as: 

    o  Senior Advisor to the Costa Rican Ambassador to the United Nations 

    o  Senior Advisor and Coordinator, Chief of Staff to the Chairman of the 
       Committee of States Parties to the International Covenant on Civil and 
       Political Rights to the United Nations 

    o  Senior Economic and Trade Advisor to the United Nations Commission on 
       Transnational Corporations
 
    Mr. Schoenfeld is the husband of Flora Schoenfeld.

STOCK OPTION PLAN 

   
   The Board of Directors has adopted, and the Company's stockholders have 
approved, the 1996 Stock Option Plan (the "Plan"). The Plan is to be 
administered by the Board of Directors or a committee thereof. Pursuant to 
the Plan, options to purchase 4,709,219 shares of Common Stock may be granted 
to directors, employees (including officers) and consultants to the Company 
(collectively, "Plan participants"). As of December 31, 1996, options to 
purchase 20,513 shares have been granted under the Plan. 

   The Plan authorizes the issuance of incentive stock options ("ISOs"), as 
defined in Section 422A of the Internal Revenue Code of 1986, as amended, and 
non-qualified stock options ("NQSOs", and together with ISOs, "Options"). 
Consultants and directors who are not also employees of the Company are 
eligible for grants of only NQSOs. The exercise price of each ISO may not be 
less than 100% of the fair market value of the Common Stock at the time of 
grant, except that in the case of a grant to an employee who owns 10% or more 
of the outstanding stock of the Company or a subsidiary or parent of the 
Company (a "10% Stockholder"), the exercise price may not be less than 110% 
of the fair market value on the date of grant. The aggregate fair market 
value of the shares covered by ISOs granted under the Plan that become 
exercisable by a Plan participant for the first time in any calendar year is 
subject to a $100,000 limitation. The exercise price of each NQSO is 
determined by the Board, or committee thereof, in its discretion; provided 
that a NQSO granted a 10% Stockholder be no less than 110% of the fair market 
value on the date of grant. 

   The Company has agreed with the Underwriters that the exercise price of 
options to purchase 4,500,000 shares of Common Stock will not be less than 
$3.50 per share and that such options will be exercisable for a period of ten 
years, commencing upon the earlier of (x) nine years after the Effective Date 
and (y) two years after the Effective Date, provided that in the case of 
clause (y), the Company shall have obtained (i) at least $30,000,000 in gross 
revenues and after tax net income of at least $2,000,000 in the second full 
fiscal year following the Effective Date, or (ii) at least $45,000,000 in 
gross revenues and $3,000,000 in after-tax net income in the third full 
fiscal year following the Effective Date, or (iii) at least $60,000,000 in 
gross revenues and $4,000,000 in after-tax net income in the fourth full 
fiscal year following the Effective Date ("Time Accelerated Restricted Stock 
Options"). 
    

   Subject to the provisions of the Plan, the Board, or committee thereof, 
has the authority to determine the individuals to whom the stock options are 
to be granted, the number of shares to be covered by each option, the type of 
option, the exercise period, the restrictions, if any, on the exercise of the 
option, the terms for the payment of the exercise price and other terms and 
conditions. Payments by holders of options upon exercise of any option may be 
made (as determined by the Board or a committee thereof) in cash or such 
other form of payment as may be permitted under the Plan.

INDEMNIFICATION OF OFFICERS AND DIRECTORS AND LIMITATION ON DIRECTORS' 
LIABILITY 

   The Company's Certificate of Incorporation provides for indemnification of 
directors and officers in conformity with Section 145 of the Delaware General 
Corporation Law, as amended (the "DGCL"), which authorizes the Company to 
indemnify any director or officer under certain prescribed circumstances and 
subject to certain limitations against certain costs and expenses, including 
attorneys' fees actually and reasonably incurred in connection with any 
action, suit or proceeding, whether civil, criminal, administrative or 
investigative, to which such person is a party by reason of being a director 
or officer of the Company if it is determined that such person acted in 
accordance with the applicable standard of conduct set forth in such 
statutory provisions. 

   Insofar as indemnification for liabilities arising under the Securities 
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 Commission such indemnification is 
against public policy as expressed in the Securities Act and is therefore 
unenforceable. 

   The Company's Certificate of Incorporation also contains a provision 
eliminating the personal liability of a director to the Company or its 
stockholders for damages for breach of fiduciary duty as a director to the 
fullest extent permitted by the DGCL, as the same exists or may thereafter be 
amended. 

                             CERTAIN TRANSACTIONS 

   
   From its inception in August 1992, the Company's operations have been 
funded through advances from Joel Schoenfeld, Flora Schoenfeld and two 
companies affiliated with Mr. Schoenfeld (collectively, the "Schoenfeld 
Parties"), and certain other stockholders of the Company. As of December 30, 
1996, the amount due to these stockholders and affiliates with respect to the 
repayment of these advances (including accrued interest) was as follows: the 
Schoenfeld Parties -- $1,160,877; Dr. Alan H. Gold -- $115,665; and John 
Frank -- $120,390. The Company issued its demand promissory notes evidencing 
its obligation to repay the foregoing advances, together with accrued 
interest on the outstanding principal amount thereof at 8% per annum. On 
December 30, 1996 and January 24, 1997, the Schoenfeld Parties and Dr. Alan 
H. Gold exchanged for cancellation their notes for an aggregate of 1,160 
shares and 115 shares, respectively, of the Company's Series A Preferred 
Stock. See "Description of Securities -- Series A Preferred Stock." 
Concurrently with the Closing, the Company will issue approximately 34,397 
shares of Common Stock to Mr. Frank, a director of the Company, in exchange 
for the cancellation of the amount payable to him ($120,390 assuming the 
Closing occurs on March 31, 1997). In addition, as of December 31, 1996, the 
Company had accrued compensation payable to the Schoenfeld Parties in the 
amount of $644,391, including management fees of $382,191 for periods prior 
to June 30, 1994. Since June 30, 1994, the Company has recorded a salary 
expense for Mr. Schoenfeld in lieu of management fees due to affiliates of 
Mr. Schoenfeld. See "Management -- Summary Compensation Table." On March 12, 
1997, the Company issued 644 shares of Series A Preferred Stock to Mr. 
Schoenfeld in exchange for the cancellation of the amount payable to him for 
unpaid compensation. 

   In connection with the formation of the Company, and in consideration for 
the dilution resulting to Joel Schoenfeld and Flora Schoenfeld (the then 
owner of all of the Company's outstanding shares) from the issuance by the 
Company of 333,333 shares and 205,128 shares to Dr. Alan H. Gold and David 
Shonfeld, respectively, each of Dr. Gold and David Shonfeld delivered to 
Flora Schoenfeld his promissory note in the amount of $750,000, the payment 
of which each of them agreed to secure by a pledge of his shares. The 
promissory notes were subsequently transferred to Joel Schoenfeld, the 
husband of Flora Schoenfeld, who is the Chief Executive Officer and Chairman 
of the Board of the Company. The promissory notes are non-interest bearing 
and payable on demand. 
    

   In connection with the Sherwood Supply Agreement, Joel Schoenfeld, Dr. 
Alan H. Gold, David Shonfeld and John Frank agreed, jointly and severally, to 
pay Sherwood up to $1,000,000 (less $0.14925 for each dollar paid to Sherwood 
under the Sherwood Supply Agreement) in the event the Company fails to pay a 
cumulative invoiced amount of $6,700,000 over the first three years of the 
Sherwood Supply Agreement. See "Business -- Suppliers." 

   On October 10, 1996, UNIVEC-NY, the then owner of all of the outstanding 
capital stock of the Company, was merged with and into the Company, solely 
for the purpose of effecting a change in its state of incorpora- 

                                      40 
<PAGE>

tion from New York to Delaware. In the merger, shareholders of UNIVEC-NY 
received 10,256.3954 shares of Common Stock for each share of UNIVEC-NY 
common stock owned, with the total number of shares issuable to each 
shareholder rounded up to the nearest whole share. 

   
   The Company occupies its executive offices, consisting of approximately 
1,200 square feet of space, pursuant to a lease which expires in December 
1998; however, the Company has the right to extend the term of the lease for 
an additional two years. Rental expense for the space is $28,704 per annum, 
subject to an increase of 4% per annum in each subsequent year. Dr. Alan H. 
Gold, the President, a Director and principal stockholder of the Company, is 
the president and a stockholder of the owner of the premises, the Long Island 
Plastic Surgical Group. 

   In December 1996, David Chabut, the Chief Financial Officer of the 
Company, exercised options to purchase 16,143 shares of Common Stock, having 
an exercise price of $3.50 per share, the exercise price of which was paid 
for by the cancellation of amounts payable to him for accrued, but unpaid 
compensation ($44,000) and certain advances ($12,500). Mr. Chabut has advised 
the Company that he intends to exercise options to purchase an additional 
4,370 shares of Common Stock (at $3.50 per share) concurrently with the 
Closing, and to pay the exercise price of these options by cancellation of 
amounts payable to him for accrued but unpaid compensation ($15,295). The 
Company has agreed to pay the remaining amount due to Mr. Chabut ($15,949) 
for federal and state withholding and payroll taxes incurred by him in 
connection with the exercise of such options. See "Management -- Stock 
Options." 

   All future transactions between the Company and its directors, officers 
and owners of more than five percent of the Company's voting securities will 
be on terms no less favorable to the Company than could be obtained from 
unaffiliated third parties and will be approved by a majority of the 
disinterested directors of the Company.

   The following table sets forth certain information concerning the

                          DESCRIPTION OF SECURITIES 

   
   The authorized capital stock of the Company consists of 25,000,000 shares 
of Common Stock, $0.001 par value per share, 2,500 shares of Series A 8% 
Cumulative Convertible Preferred Stock, $0.001 par value per share (the 
"Series A Preferred Stock"), and 4,997,500 shares of "blank check" preferred 
stock, $0.001 par value per share. On the Effective Date, 1,082,287 shares of 
Common Stock and 1,919 shares of Series A Preferred Stock will be issued and 
outstanding. 
    

   The following are brief descriptions of the securities offered hereby and 
other securities of the Company. The rights of the holders of shares of the 
Company's capital stock are established by the Company's Certificate of 
Incorporation, a Certificate of Designation authorizing the Series A 
Preferred Stock, the Company's By-laws and Delaware law. The following 
statements do not purport to be complete or give full effect to statutory or 
common law, and are subject in all respects to the applicable provisions of 
the Certificate of Incorporation, the Certificate of Designation, By-laws and 
state law. 

COMMON STOCK 

   Holders of the Common Stock are entitled to one vote per share, and 
subject to the rights of holders of the Series A Preferred Stock or any other 
series of preferred stock, to receive dividends when, as and if declared by 
the Board of Directors and to share ratably in the assets of the Company 
legally available for distribution to holders of Common Stock in the event of 
the liquidation, dissolution or winding up of the Company. Holders of the 
Common Stock do not have subscription, redemption, conversion or preemptive 
rights. 

   Each share of Common Stock is entitled to one vote on any matter submitted 
to the holders, including the election of directors. Holders of Common Stock 
do not have cumulative voting rights; therefore, holders of a majority of the 
outstanding shares of Common Stock entitled to vote for the election of 
Directors may elect all of the Directors to be elected, if they so choose, 
and in such event, the holders of the remaining shares will not be able to 
elect any of the Company's Directors. Except as otherwise required by the 
DGCL, all stockholder action (other than the election of Directors, who are 
elected by plurality vote), is subject to approval by a majority of the 
shares of Common Stock present at a stockholders' meeting at which a quorum 
(a majority of the issued and outstanding shares of Common Stock) is present 
in person or by proxy, or by written consent pursuant to Delaware law. 

   All shares of Common Stock outstanding are fully paid and non-assessable, 
and the shares of Common Stock offered hereby and the shares of Common Stock 
issuable upon exercise of the Warrants, when issued upon payment of the 
purchase price set forth on the cover page of the Prospectus or payment of 
the exercise price specified in the Warrants, as the case may be, will be 
fully paid and non-assessable. 

   
   The Board of Directors is authorized to issue additional shares of Common 
Stock within the limits authorized by the Company's Certificate of 
Incorporation without further stockholder action. The Company has agreed with 
the Underwriters that it will not issue any securities, including but not 
limited to shares of Common Stock, for a period of 24 months following the 
Effective Date, except as disclosed in or contemplated by this Prospectus, 
without the prior written consent of the Representative. 
    

WARRANTS 

   The Warrants offered hereby will be issued in registered form under a 
Warrant Agreement (the "Warrant Agreement") between the Company and 
Continental Stock Transfer & Trust Company, as Warrant Agent (the "Warrant 
Agent"). 

   Each Warrant will be separately transferable and will entitle the 
registered holder thereof to purchase one share of Common Stock at $4.50 per 
share (subject to adjustment as described below) for a period of five years 
commencing ______, 1999 [two years after the Effective Date] and ending 
______, 2002 [five years after the Effective Date] (the "Exercise Period"). 
The exercise price and the number of shares of Common Stock issuable upon the 
exercise of each Warrant are subject to adjustment in the event of a stock 
split, stock dividend, recapitalization, merger, consolidation or certain 
other events. A holder of Warrants may exercise such Warrants by surrendering 
the certificate evidencing such Warrants to the Warrant Agent, together with 
the form 

                                      43
<PAGE>

of election to purchase on the reverse side of such certificate attached 
thereto properly completed and executed and the payment of the exercise price 
and any transfer tax. If less than all of the Warrants evidenced by a Warrant 
certificate are exercised, a new certificate will be issued for the remaining 
number of Warrants. 

   The Company has authorized and reserved for issuance a number of shares of 
Common Stock sufficient to provide for the exercise of the Warrants. When 
issued, upon payment of the exercise price specified in the Warrants, each 
share of Common Stock will be fully paid and nonassessable. Holders of 
Warrants will not have any voting or other rights as stockholders of the 
Company unless and until Warrants are exercised and shares issued pursuant 
thereto. 

   
   The Warrants may be redeemed by the Company, at a price of $.05 per 
Warrant, upon not less than 30 days prior written notice at any time during 
the Exercise Period, with the prior written consent of the Representative, 
provided the average of the closing bid quotations of the Common Stock, 
during the period of twenty (20) consecutive trading days ending on the third 
day prior to the date upon which notice of redemption is given, as reported 
on The Nasdaq SmallCap Market (or if the Common Stock is not quoted thereon, 
the closing sale price of the Common Stock on the Nasdaq National Market or 
other principal securities exchange upon which the Common Stock is then 
quoted or listed, or such other reporting system that provides closing sale 
prices for the Common Stock), has been at least $8.00 per share. The Warrants 
will be exercisable until the close of business on the day immediately 
preceding the date fixed for the redemption of the Warrants in the notice of 
redemption. 

   The Company will pay the Representative a fee of 8% of the exercise price 
of each Warrant exercised, provided (i) the market price of the Common Stock 
on the date the Warrant was exercised was equal to or greater than the 
Warrant exercise price on that date, (ii) the exercise price of the Warrant 
was solicited by a member of the NASD, (iii) the Warrant was not held in a 
discretionary account, (iv) the disclosure of compensation arrangements was 
made in documents provided to the holders of the Warrants, (v) the 
solicitation of the exercise of the Warrant was not a violation of Rule 101 
of Regulation M under the Exchange Act and (vi) the Representative is 
designated in writing as the soliciting NASD member. The Representative and 
any other soliciting broker/dealers will be prohibited from engaging in any 
market making activities or solicited brokerage activities with regard to the 
Company's securities during the periods prescribed by Rule 101 of Regulation 
M before the solicitation of the exercise of any Warrant until the later of 
the termination of such solicitation activity or the termination of any right 
the Representative and any other soliciting broker/dealer may have to receive 
a fee for the solicitation of the exercise of the Warrants. 
    

   For a holder of a Warrant to exercise the Warrant, there must be a current 
registration statement on file with the Securities and Exchange Commission 
and various state securities commissions. The Company will be required to 
file post-effective amendments to the registration statement when events 
require such amendments and to take appropriate action under state securities 
laws. While it is the Company's intention to file post-effective amendments 
when necessary and to take appropriate action under state securities laws, 
there can be no assurance that the Company will file all post-effective 
amendments required to maintain the effectiveness of the registration 
statement or that the Company will take all appropriate action under state 
securities laws. If the registration statement is not kept current for any 
reason, the Warrants will not be exercisable, and holders thereof may be 
deprived of value. 

OPTIONS AND WARRANTS 

   Options. On the Effective Date, there will be outstanding options to 
purchase an aggregate of 60,042 shares of Common Stock at an exercise price 
of $3.50, which expire at various dates from February 22, 1999 through June 
30, 1999. David Chabut, Chief Financial Officer of the Company, has advised 
the Company that he intends to exercise options to purchase 4,370 shares of 
Common Stock at the Closing. See "Certain Transactions." In addition, 
4,688,706 shares of Common Stock have been reserved for issuance upon 
exercise of options which may be granted in the future pursuant to the 
Company's 1996 Stock Option Plan, including 4,500,000 Time Accelerated 
Restricted Stock Options. See "Management -- Stock Option Plan."

   The Company is authorized to issue up to 5,000,000 shares of "blank check" 
preferred stock with such designations, rights and preferences as may be 
determined from time to time by the Board of Directors. Accordingly, the 
Board of Directors is empowered, without further stockholder approval, to 
issue preferred stock with dividend, liquidation, conversion, voting or other 
rights that could decrease the amount of earnings and assets available for 
distribution to holders of Common Stock or adversely affect the voting power 
or other rights of the holders of the Company's Common Stock. In the event of 
issuance, the preferred stock could be utilized, under certain circumstances, 
as a method of discouraging, delaying or preventing a change in control of 
the Company. No shares of preferred stock will be outstanding on the 
Effective Date, other than the 1,919 shares of Series A Preferred Stock owned 
by the Schoenfeld Parties and Dr. Alan H. Gold. Except for shares of Series A 
Preferred Stock which may be issued in payment of dividends on the Series A 
Preferred Stock, the Company has no present intention to issue any shares of 
preferred stock. The Company has agreed with the Underwriters that, except 
for issuances disclosed in or contemplated by this Prospectus, it will not 
issue any securities, including but no limited to any shares of preferred 
stock, for a period of 24 months following the Effective Date, without the 
prior written consent of the Representative. See "Certain Transactions" and 
"Description of Securities -- Series A Preferred Stock." 
    

SERIES A PREFERRED STOCK 

   
   The Board of Directors has authorized the issuance of up to 2,500 shares 
of Series A Preferred Stock, of which 1,919 shares, owned by the Schoenfeld 
Parties and Dr. Alan H. Gold are outstanding. The terms of the Series A 
Preferred Stock, set forth in a Certificate of Designation filed with the 
Office of the Secretary of the State for the State of Delaware, are as 
follows: 

   Dividend Rights. Holders of Series A Preferred Stock are entitled to 
receive, prior to the payment of cash dividends on the Common Stock, 
cumulative dividends at the rate of $80 per share per annum, and no more, 
when, as and if declared by the Company's Board of Directors, out of funds 
legally available therefor. Dividends on the Series A Preferred Stock are 
payable, in the sole and absolute discretion of the Board of Directors, in 
cash, additional shares of Series A Preferred Stock (based upon the 
liquidation value thereof), or a combination thereof. Dividends may not be 
paid or declared on, and no other distributions may be made with respect to, 
and no expenditure shall be made for the purchase, redemption or retirement 
of, any of the Company's capital stock junior to or in parity with the Series 
A Preferred Stock, unless all cumulative dividends payable on the Series A 
Preferred Stock for all prior annual dividend periods have been paid. The 
Company has agreed with the Underwriters that it will not declare or pay any 
cash dividends on the Series A Preferred Stock without the prior written 
consent of the Representative. 

   Redemption. The Series A Preferred Stock may be redeemed at the option of 
the Company, as a whole at any time or in part from time to time, at $1,000 
per share. Written notice of redemption must be given to the registered 
holders of the Series A Preferred Stock not less than twenty (20) nor more 
than thirty (30) days prior to the date fixed for the redemption of the 
Series A Preferred Stock. The Company has agreed with the Underwriters that 
it will not redeem any shares of Series A Preferred Stock prior to the fifth 
anniversary of the Effective Date, without the prior written consent of the 
Representative. 
    

   Liquidation Rights. Subject to the prior rights of the Company's creditors 
and the holders of senior securities, the holders of the Series A Preferred 
Stock are entitled to receive, upon any voluntary or involuntary liquidation, 
dissolution or winding-up of the Company, $1,000 per share, plus accrued and 
unpaid dividends. If, in any such case, the assets of the Company are 
insufficient to make such payment in full, then the available assets will be 
distributed among the holders of the Series A Preferred Stock and any other 
series of preferred stock which is in parity with the Series A Preferred 
Stock, ratably in proportion to the full amount to which each holder would be 
entitled. 

   Conversion Rights. Each share of Series A Preferred Stock is convertible 
into 222.22 shares of Common Stock (the "conversion rate"), subject to 
adjustment in certain events, at the option of the holder thereof commencing 
upon the earlier of September 30, 1999 and 24 months after the Effective 
Date. The conversion rate is subject to adjustment in the event of a stock 
split, stock dividend, recapitalization, merger, consolidation or cer 

                                      45 
<PAGE>

tain other events. The right of conversion with respect to the shares of the 
Series A Preferred Stock called for redemption will terminate at the close of 
business on the business day preceding the date fixed for redemption. Upon 
conversion, no payment or allowance will be made in respect of any accrued 
but unpaid dividends on the Series A Preferred Stock. 

   Voting Rights. Holders of Series A Preferred Stock have no voting rights, 
except as may be required by law. 

STATUTORY PROVISIONS AFFECTING STOCKHOLDERS 

   Following the consummation of the Offering, the Company will be subject to 
Section 203 of the Delaware General Corporation Law, the State of Delaware's 
"business combination" statute. In general, such statute prohibits a publicly 
held Delaware corporation from engaging in various "business combination" 
transactions with any "interested stockholder" for a period of three years 
after the date of the transaction in which the person became an "interested 
stockholder," unless (i) the transaction in which the interested stockholder 
obtained such status or the business combination is approved by the Board of 
Directors prior to the date the interested stockholder obtained such status; 
(ii) upon consummation of the transaction which resulted in the stockholder 
becoming an "interested stockholder," the "interested stockholder" owned at 
least 85% of the voting stock of the corporation outstanding at the time the 
transaction commenced, excluding for purposes of determining the number of 
shares outstanding those shares owned by (a) persons who are directors and 
officers and (b) employee stock plans in which employee participants do not 
have the right to determine confidentially whether shares held subject to the 
plan will be tendered in a tender or exchange offer; or (iii) on or 
subsequent to such date the "business combination" is approved by the Board 
of Directors and authorized at an annual or special meeting of stockholders 
by the affirmative vote of at least 66 2/3 % of the outstanding voting stock 
which is not owned by the "interested stockholder." A "business combination" 
includes mergers, asset sales and other transactions resulting in financial 
benefit to a stockholder. An "interested stockholder" is a person who, 
together with affiliates and associates, owns (or within three years, did 
own) 15% or more of a corporation's voting stock. The statute could prohibit 
or delay mergers or other takeover or change in control attempts with respect 
to the Company and, accordingly, may discourage attempts to acquire the 
Company. 

BRIDGE FINANCING 

   
   In November and December 1996, the Company sold an aggregate of 40 Units, 
each Unit consisting of the Company's 8% promissory note in the principal 
amount of $25,000 (the "Bridge Notes") and Bridge Warrants to purchase 62,500 
shares of Common Stock for a purchase price of $25,000 per Unit (or an 
aggregate of $1,000,000). The Bridge Notes are payable upon the earlier of 
November 27, 1997 or the consummation of an initial public offering or 
private placement of the Company's debt and/or equity securities resulting in 
gross proceeds to the Company of at least $5,000,000. Each Bridge Warrant 
entitles the registered holder thereof to purchase one share of Common Stock 
at an exercise price of $4.50 per share, subject to adjustment in certain 
events, at any time during the period commencing November 27, 1997 and ending 
on November 26, 2001. On the Effective Date, the Bridge Warrants will convert 
automatically into warrants having terms identical to the Warrants being 
offered in the Offering. The net proceeds of the Bridge Financing 
(approximately $820,000) were used in part to purchase machinery ($235,000) 
and for sales and marketing ($235,000). The Company used the remaining net 
proceeds as working capital, including the payment of some of the expenses of 
the Offering. 
    

REGISTRATION RIGHTS 

   Investors who acquired Bridge Warrants in connection with the Bridge 
Financing have the right to request registration of the Bridge Warrants (or 
securities issued in exchange therefor) and the shares of Common Stock issued 
or issuable upon exercise thereof in any registration statement filed by the 
Company with the Commission under the Securities Act (with certain 
exceptions) for the issuance and sale of its securities. The Company has 
registered for resale pursuant to the Selling Securityholder Prospectus 
warrants to purchase 2,250,000 shares of Common Stock (having terms identical 
to the Warrants offered hereby) which are to be issued on the Effective Date 
upon automatic conversion of the Bridge Warrants, and the shares of Common 
Stock issuable upon exercise of those warrants. The Company also has 
registered for resale pursuant to the Selling Securityholder 

                                      46 
<PAGE>

   
Prospectus 33,436 shares of Common Stock issuable upon exercise of an option 
granted to an individual who through an affiliated entity, provided the 
Company with debt financing in 1995. The Company granted that individual 
piggyback and demand registration rights with respect to those shares. 
Investors in the Bridge Financing and the optionee have agreed not to sell or 
otherwise dispose of securities of the Company, including shares of Common 
Stock (except under certain circumstances in connection with a third party 
tender offer for the Common Stock), for a period of 24 months following the 
Effective Date, without the prior written consent of the Representative, 
which may be granted or withheld in the sale and absolute discretion of the 
Representative. See "Selling Securityholder Offering." 
    

SHARES ELIGIBLE FOR FUTURE SALE 

   
   Upon completion of the Offering, the Company will have 2,621,054 shares of 
Common Stock outstanding, of which 1,500,000 will be transferable under the 
Securities Act. The remaining 1,121,054 shares, issued in private 
transactions, will be "restricted securities" (as that term is defined in 
Rule 144 promulgated under the Securities Act) which may be publicly sold 
only if registered under the Securities Act or if sold in accordance with an 
applicable exemption from registration, such as Rule 144. In general, under 
Rule 144 as currently in effect, subject to the satisfaction of certain other 
conditions, a person, including an affiliate of the Company, who has 
beneficially owned restricted securities for at least two years (which 
holding period will be reduced to one year under an amendment to Rule 144 
that becomes effective April 29, 1997), is entitled to sell (together with 
any person with whom such individual is required to aggregate sales), within 
any three-month period, a number of shares that does not exceed the greater 
of 1% of the total number of outstanding shares of the same class, or, if the 
Common Stock is quoted on The Nasdaq Stock Market or a national securities 
exchange, the average weekly trading volume during the four calendar weeks 
preceding the sale. A person who has not been an affiliate of the Company for 
at least three months, and who has beneficially owned restricted securities 
for at least three years (which holding period will be reduced to two years 
under an amendment to Rule 144 that becomes effective April 29, 1997) is 
entitled to sell such restricted shares under Rule 144 without regard to any 
of the limitations described above. Officers, directors and other 
securityholders of the Company owning and/or having rights to acquire in the 
aggregate 3,676,726 shares of Common Stock, have entered into agreements not 
to sell or otherwise dispose of any securities of the Company, including 
shares of Common Stock, for a period of 24 months following the Effective 
Date (the "Lock-Up Agreements"), without the prior written consent of the 
Representative, which may be granted or withheld at the sole and absolute 
discretion of the Representative; provided, however, that if during such 24 
month period, the Company's shares of Common Stock are subject to a tender 
offer and holders of the Company's Common Stock (other than the existing 
stockholders) agree to tender a majority of the outstanding shares of Common 
Stock to the offeror, then the Representative shall release all stockholders 
subject to the Lock-Up Agreement from the restrictions imposed thereby solely 
for the purpose of tendering their shares of Common Stock to the offeror 
pursuant to the terms of the tender offer. The Company has registered for 
resale pursuant to the Selling Securityholder Prospectus (i) warrants to 
purchase 2,500,000 shares of Common Stock (having terms identical to the 
Warrants offered hereby) and the shares of Common Stock issuable upon 
exercise thereof, and (ii) 33,436 shares of Common Stock issuable upon 
exercise of options, subject to the Lock-Up Agreements. Following expiration 
of the term of the Lock-Up Agreements, or the earlier release of the 
restrictions contained therein, 1,121,054 shares will become eligible for 
resale pursuant to Rule 144, subject to the volume limitations and compliance 
with the other provisions of Rule 144, assuming the sale of all shares 
pursuant to the Selling Securityholder Prospectus. Furthermore, the holders 
of the Underwriters' Warrants (including the securities issuable upon 
exercise thereof) have demand and piggyback registration rights with respect 
to the shares of Common Stock and Warrants issuable upon exercise of the 
Underwriters' Warrants. See "Description of Securities -- Registration 
Rights," "Certain Transactions," "Underwriting" and "Selling Securityholder 
Offering." 
    

   As a result of the Offering, an additional 2,250,000 shares of Common 
Stock (2,587,500 if the Over- Allotment Option is fully exercised) will be 
subject to issuance upon the exercise of the Warrants offered hereby. 

   As of March 1, 1996, there were eight record holders of the Common Stock.

DIVIDEND POLICY 

   Since its inception, the Company has not paid any dividends on its Common 
Stock and it does not anticipate paying such dividends in the foreseeable 
future. The Company intends to retain earnings, if any, to finance its 
operations. 

REPORTS TO STOCKHOLDERS 

   The Company intends to furnish its stockholders with annual reports 
containing financial statements audited and reported upon by its independent 
certified public accountants after the end of each fiscal year, and will make 
available such other periodic reports as the Company may deem to be 
appropriate or as may be required by law. The Company's fiscal year end is 
December 31. Prior to the Effective Date, the Company will file a 
Registration Statement on Form 8-A with the Commission to register under, and 
be subject to the reporting requirements of, the Exchange Act. 

TRANSFER AGENT AND WARRANT AGENT 

   The Company has engaged Continental Stock Transfer & Trust Company to act 
as Transfer Agent for the Company's Common Stock and Warrant Agent for the 
Warrants.

   Subject to the terms and conditions of the underwriting agreement (the 
"Underwriting Agreement"), the Company has agreed to sell to the Underwriters 
named below, for whom Maidstone Financial Inc. is acting as representative 
(in such capacity, the "Representative"), and the Underwriters have 
severally, and not jointly, agreed to purchase, the number of shares of 
Common Stock and Warrants set forth opposite their respective names below.

</TABLE>

   
The Underwriting Agreement provides that the obligations of the Underwriters 
are subject to certain conditions precedent. The Underwriters are committed 
to purchase all of the shares of Common Stock and Warrants offered hereby, if 
any are purchased. 

   The Representative has advised the Company that the Underwriters propose 
initially to offer the 1,500,000 shares of Common Stock and 2,250,000 
Warrants to the public at the respective initial public offering prices set 
forth on the cover page of this Prospectus and that it may allow to selected 
dealers who are members of the NASD concessions not in excess of $  per share 
of Common Stock and $  per Warrant, of which not more than $  per share of 
Common Stock and $  per Warrant may be re-allowed to certain other dealers. 

   The Underwriting Agreement also provides that the Representative will 
receive a non-accountable expense allowance of 3% of the gross proceeds of 
the Offering, of which $55,000 has been paid by the Company to date. The 
Company also has agreed to pay all expenses in connection with qualifying the 
shares of Common Stock and the Warrants offered hereby for sale under the 
laws of such states as the Representative may designate, including expenses 
of counsel retained for such purpose by the Underwriters. 

   Pursuant to the Over-allotment Option, which is exercisable for a period 
of 45 days after the closing of the Offering, the Underwriters may purchase 
up to 15% of the total number of shares of Common Stock and Warrants offered 
hereby, solely to cover over-allotments. 

   The Company has agreed to sell to the Underwriters, for nominal 
consideration, the Underwriters' Warrants to purchase an amount equal to 10% 
of the number of shares of Common Stock and Warrants sold to the public. The 
Underwriters' Warrants shall be exercisable for a period of five years 
commencing one year from the Effective Date at an exercise price equal to 
165% of the offering price of the shares of Common Stock and Warrants sold to 
the public in the Offering. The Underwriters' Warrants are not transferable 
for a period of one year after the Effective Date, except to officers of the 
Underwriters, members of the selling group and their officers and partners. 

   The Company has agreed that, upon written request of the then holder(s) of 
a majority of the Warrants and the shares of Common Stock issued and/or 
issuable upon exercise of the Underwriters' Warrants (the "Underwriters' 
Warrant Shares") which were originally issued to the Underwriters or to its 
designees, made at any time within the period commencing one year and ending 
five years after the Effective Date, the Company will file, at its sole 
expense, no more than once, a registration statement under the Securities Act 
registering the Underwriters' Warrant Shares. The Company has agreed to use 
its best efforts to cause the registration statement to become effective. The 
holders of the Underwriter's Warrants may demand registration without 
exercising the Underwriters' Warrants and, in fact, are never required to 
exercise same. 

   The Company has also agreed that if, at any time within the period 
commencing one year and ending five years after the Effective Date, it should 
file a registration statement with the Commission pursuant to the Securities 
Act, regardless of whether some of the holders of the Underwriters' Warrants 
and the Underwriters' Warrant Shares shall have therefore availed themselves 
of any of the registration rights above, the Company, at its own expense, 
will offer to said holders (with certain exceptions) the opportunity to 
register or qualify the Underwriters' Warrant Shares. The objection of a 
subsequent underwriter to the above "piggyback" registration rights would 
preclude such inclusion. 
    
                                      49
<PAGE>

   
   In addition to the demand and "piggyback" registration rights, the Company 
will cooperate with the then holders of the Underwriters' Warrants and 
Underwriters' Warrant Shares in the preparation and execution of any 
registration statement required in order to sell or transfer the 
Underwriters' Warrant Shares and will supply all information required 
therefore, but such additional expenses of such registration statement will 
be pro-rated between the Company and the holders of the Underwriters' 
Warrants and Underwriters' Warrant Shares according to the aggregate sales 
price of the securities being issued. 

   For the life of the Underwriters' Warrants, the holders thereof are given, 
at nominal cost, the opportunity to profit from a rise in the market price of 
the Common Stock with a resulting dilution in the interest of other 
stockholders. Further, such holders may be expected to exercise the 
Underwriters' Warrants at a time when the Company would in all likelihood be 
able to obtain equity capital on terms more favorable than those provided in 
the Underwriters' Warrants. 

   In connection with this Offering, certain Underwriters and selling group 
members and their respective affiliates may engage in transactions that 
stabilize, maintain or otherwise affect the market price of the Common Stock 
and Warrants. Such transactions may include stabilization transactions 
effected in accordance with Rule 104 of Regulation M, pursuant to which such 
persons may bid for or purchase Common Stock or Warrants for the purpose of 
stabilizing their respective market prices, The Underwriters also may create 
a short position for the account of the Underwriters by selling more shares 
of Common Stock or Warrants in connection with the Offering than they are 
committed to purchase from the Company, and in such case may purchase shares 
of Common Stock or Warrants in the open market following completion of the 
Offering to cover all or a portion of such short position. The Underwriters 
may also cover all or a portion of such short position by exercising the 
Over-Allotment Option. In addition, the Representative, on behalf of the 
Underwriters, may impose "penalty bids" under contractual arrangements with 
the Underwriters whereby it may reclaim from an Underwriter (or dealer 
participating in the Offering) for the account of other Underwriters, the 
selling concession with respect to shares of Common Stock and Warrants that 
are distributed in the Offering but subsequently purchased for the account of 
the Underwriters in the open market. Any of the transactions described in 
this paragraph may result in the maintenance of the price of the Common Stock 
and Warrants at a level above that which might otherwise prevail in the open 
market. None of the transactions described in this paragraph is required, 
and, if they are undertaken they may be discontinued at any time. 

   The Company has agreed, for a period of 24 months after the Effective 
Date, not to issue any shares of Common Stock, preferred stock or any 
warrants, options or other rights to purchase Common Stock or preferred stock 
without the prior written consent of the Representative, except as 
contemplated by or as disclosed in the Prospectus. Officers, directors and 
other securityholders of the Company owning and/or having rights to acquire 
in the aggregate 3,653,343 shares of Common Stock have entered into 
agreements not to sell or otherwise dispose of any securities of the Company, 
including shares of Common Stock (except under certain circumstances in 
connection with a third party tender offer for the Common Stock), for a 
period of 24 months following the Effective Date, without the prior written 
consent of the Representative, which may be granted or withheld in the sole 
and absolute discretion of the Representative. See "Description of Securities 
- -- Shares Eligible for Future Sale." 

   The Underwriting Agreement provides for reciprocal indemnification between 
the Company and the Underwriters against liabilities in connection with the 
Offering, including liabilities under the Securities Act. 

   The Company has agreed that upon closing of the Offering it will, for a 
period of not less than three years, engage a designee of the Representative 
as advisor to the Board. In addition and in lieu of the Representative's 
right to designate an advisor, the Company has agreed, if requested by the 
Representative during such three year period, to nominate and use its best 
efforts to cause the election of a designee of the Representative as a 
director of the Company. The Representative has not yet designated any such 
person. 

   The Representative intends to act as a market maker for the Common Stock 
and Warrants after the closing of the Offering. 

   The Company will pay the Representative a fee of 8% of the exercise price 
of each Warrant exercised, provided (i) the market price of the Common Stock 
on the date the Warrant was exercised was equal to or greater than the 
Warrant exercise price on that date, (ii) the exercise price of the Warrant 
was solicited by a member of 
    

                                      50
<PAGE>

   
the NASD, (iii) the Warrant was not held in a discretionary account, (iv) the 
disclosure of compensation arrangements was made in documents provided to the 
holders of the Warrants, (v) the solicitation of the exercise of the Warrant 
was not a violation of Rule 101 of Regulation M under the Exchange Act and 
(vi) the Representative is designated in writing as the soliciting NASD 
member. The Representative and any other soliciting broker/dealers will be 
prohibited from engaging in any market making activities or solicited 
brokerage activities with regard to the Company's securities during the 
periods prescribed by Rule 101 of Regulation M before the solicitation of the 
exercise of any Warrant until the later of the termination of such 
solicitation activity or the termination of any right the Representative and 
any other soliciting broker/dealer may have to receive a fee for the 
solicitation of the exercise of the Warrants. 

   The Representative acted as placement agent for the Bridge Financing, for 
which it received selling commissions of $100,000 and a non-accountable 
expense allowance of $30,000. 

   The Company has agreed to retain the Representative as a management and 
financial advisor for a period of 24 months commencing on the Effective Date 
at a fee equal to $4,000 per month. The entire fee ($96,000) is payable at 
the closing of the Offering. In its capacity as an advisor to the Company, 
the Representative will be obligated to provide general financial advisory 
services to the Company on an as-needed basis with respect to possible future 
financing or acquisitions by the Company and related matters. The 
Representative is not obligated to provide any minimum number of hours of 
advisory services to the Company. 

   In addition, the Company has agreed to engage a financial public relations 
firm reasonably satisfactory to the Representative no later than the 
Effective Date. Such firm, or an acceptable substitute firm, shall be 
continuously engaged from the Effective Date to a date 24 months from the 
closing of the Offering. 

   The initial public offering prices of the shares of Common Stock and 
Warrants offered hereby and the initial exercise price and other terms of the 
Warrants have been determined by negotiation between the Company and the 
Representative and do not necessarily bear any direct relationship to the 
Company's assets, earnings, book value per share or other generally accepted 
criteria of value. Factors considered in determining the offering prices of 
the shares of Common Stock and Warrants and the exercise price of the 
Warrants included the business in which the Company is engaged, the Company's 
financial condition, an assessment of the Company's management, the general 
condition of the securities markets and the demand for similar securities of 
comparable companies. 
    

                         SELLING STOCKHOLDER OFFERING 

   
   The Company has registered for resale under a separate prospectus (the 
"Selling Securityholder Prospectus") as part of the Registration Statement 
warrants to purchase 2,500,000 shares of Common Stock (having terms identical 
to the warrants offered hereby) and the shares of Common Stock issuable upon 
exercise thereof, and 33,436 shares of Common Stock issuable upon exercise of 
an option granted to an individual who, through an affiliated entity, 
provided debt financing to the Company in 1995. Those warrants were issued in 
connection with a bridge financing completed by the Company in December 1996. 
Prior to the Effective Date, each of the selling securityholders named in the 
Selling Securityholder Prospectus (the "Selling Securityholders") will enter 
into an agreement not to sell or otherwise dispose of any securities of the 
Company (except under certain circumstances in connection with a third party 
tender offer for the Common Stock) for a period of 24 months following the 
Effective Date, without the prior written consent of the Representative, 
which may be granted or withheld in the sole and absolute discretion of the 
Representative. The Representative has agreed that it will not consent to the 
sale of any of the securities offered by the Selling Securityholders pursuant 
to the Selling Stockholder Prospectus prior to the date upon which the 
Over-Allotment Option expires, or such earlier date upon which the 
Over-Allotment Option is fully exercised. See "Description of Securities -- 
Bridge Financing," "Description of Securities -- Registration Rights" and 
"Description of Securities -- Shares Eligible for Future Sale." 
    

   The Company will not receive any proceeds from the sale of the warrants or 
shares of Common Stock by the Selling Securityholders, but will receive the 
exercise price of the warrants and options exercised. Sales of the securities 
offered by the Selling Securityholders, or even the potential for such sales,

REPORT OF INDEPENDENT ACCOUNTANTS 

To the Board of Directors and Stockholders of Univec, Inc.: 

   
   We have audited the accompanying consolidated balance sheet of Univec, 
Inc. and Subsidiary (the "Company") as of December 31, 1996 and the related 
consolidated statements of operations, stockholders' deficiency and cash 
flows for each of the two years in the period ended December 31, 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 consolidated financial position of Univec, Inc. 
and Subsidiary as of December 31, 1996 and the consolidated results of their 
operations and their cash flows for each of the two years in the period ended 
December 31, 1996, in conformity with generally accepted accounting 
principles. 

   
   The accompanying financial statements have been prepared assuming that the 
Company will continue as a going concern. As discussed in Note 2 to the 
consolidated financial statements, the Company has suffered recurring losses 
from operations since its inception and has a net capital deficiency that 
raises substantial doubt about the Company's ability to continue as a going 
concern. Management's plans with regard to these matters are also discussed 
in Note 2. The financial statements do not include any adjustments relating 
to the recoverability and classification of asset carrying amounts or the 
amount and classification of liabilities that might result should the Company 
be unable to continue as a going concern.

Note 15 as to which 
the date is March 12, 
1997.

                         UNIVEC, INC. AND SUBSIDIARY 

                  Notes to Consolidated Financial Statements 

1. OPERATIONS AND REORGANIZATION: 

   Univec, Inc. (the "Company" or "Univec") was incorporated on August 18, 
1992 in the State of New York. The Company was formed to develop, produce, 
market medical products and resell medical devices of other companies on a 
global basis. 

   On October 7, 1996, the Company formed a wholly-owned subsidiary organized 
under the laws of Delaware. The new corporation has been authorized with 
25,000,000 shares of common stock, $.001 par value and 5,000,000 shares of 
preferred stock, $.001 par value. The Company merged with its wholly-owned 
subsidiary, with the wholly-owned subsidiary being the surviving corporation. 
Accordingly, the Company issued 10,256 for each outstanding common share of 
the parent company. The accompanying financial statements of the Company 
retroactively reflect the foregoing reorganization to present the current 
capitalization. 

2. GOING CONCERN: 

   The financial statements have been prepared on a going concern basis, 
which contemplates realization of assets and liquidation of liabilities in 
the ordinary course of business. The Company has a working capital deficit of 
$1,066,521 and a stockholders' deficiency of $1,885,138 as of December 31, 
1996. The ability to continue as a going concern is dependent, among other 
things, upon the Company's obtaining adequate long-term financing and the 
attainment of profitable commercial operations. Management has signed a 
letter of intent to raise additional working capital through an initial 
public offering ("IPO"). 

   Although management expects that the above factors will allow the Company 
to continue as a going concern, there is no assurance that the financing will 
be consummated or revenues from product sales will generate profitable 
operations. The financial statements do not include any adjustments that 
might result from the outcome of this uncertainty. 
   
3. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES: 

BASIS OF PRESENTATION 
    

   The consolidated financial statements include the accounts of the Company 
and its wholly-owned subsidiary, Rx Ultra, Inc., which was incorporated on 
February 2, 1996. All material intercompany balances and transactions have 
been eliminated. 

CASH AND CASH EQUIVALENTS 
   
   The Company considers all highly liquid debt instruments, purchased with 
original maturities of three months or less, to be cash equivalents. At 
December 31, 1996, the Company had $32,500 of restricted cash which is to be 
used to pay costs associated with the private placement (see Note 10). 
    
INVENTORY 

   Inventory is valued at the lower of cost, determined by the first-in, 
first-out method, or market. 

FIXED ASSETS 
   
   Fixed assets are stated at original cost less accumulated depreciation. 
Fixed assets are depreciated on a straight-line basis over a five to 
seven-year useful life depending on the nature of the asset. Maintenance and 
repairs are charged to expense as incurred; renewals and improvements which 
extend the life of assets are capitalized. Gains or losses on the disposal of 
fixed assets are charged to operations.

          Notes to Consolidated Financial Statements  - (Continued) 

PATENT RIGHTS AND ROYALTIES 

   Patent rights acquired are capitalized and amortized on a straight line 
basis over an estimated useful life of seven years. Royalties based on future 
revenues will be charged to operations when and if they are incurred (see 
Note 5). 

PRODUCT DEVELOPMENT 

   Research and development costs are expensed as incurred. 

INCOME TAXES 
   
   The Company records its income taxes under the provisions of the Statement 
of Financial Accounting Standards No. 109 "Accounting for Income Taxes," 
(SFAS No. 109). This method requires recognition of deferred tax liabilities 
and assets for the expected future tax consequences of events that have been 
included in the financial statements or tax returns. Under SFAS No. 109, 
deferred tax liabilities and assets are determined based on the difference 
between the financial statement and tax bases of assets and liabilities using 
enacted tax rates in effect for the year in which the differences are 
expected to reverse (see Note 11). 
    
   The Company had elected treatment as an S corporation for Federal and 
state income taxation as of January 1, 1995. S corporation taxable income, 
whether distributed or not, is passed through and taxed at the stockholder 
level. Accordingly, for the above referenced period, no provision for Federal 
income taxes is included in the accompanying statements of operations. 

LOSS PER SHARE 

   Loss per share has been computed by dividing net losses by the weighted 
average number of common shares outstanding during each period. Retroactive 
restatement has been made to all share and per share amounts for the 
reorganization discussed in Note 1. 
   
   Pro forma loss per share does not differ from historical loss per share, 
and there is no effect in converting from an S corporation to a C corporation 
in 1996 and 1995. 

REVENUE RECOGNITION 

   Revenues are recognized when products are shipped. Unearned income in 
connection with the supply and licensing agreements are recognized upon sale 
of the product supplied by the manufacturer (see Note 12). 
    
ESTIMATES 

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

   At December 31, 1996, the Company has deferred offering costs aggregating 
$92,500, in connection with an expected public offering of its equity 
securities. If the offering is unsuccessful, such costs will be charged to 
operations. 
   
DEBT FINANCING COSTS 

   At December 31, 1996, the Company has incurred debt issuance costs 
aggregating $783,292 in connection with a private placement of debt completed 
during December 1996 (see Note 10). These costs have been capitalized and are 
being amortized to interest expense using the effective interest method over 
the life of the related debt. As of December 31, 1996, $71,208 of such costs 
was charged to interest expense.

          Notes to Consolidated Financial Statements  - (Continued) 

CONCENTRATION OF CREDIT RISK 

   Financial instruments which potentially subject the Company to 
concentration of credit risk consist of cash deposits. Cash balances are held 
principally at one financial institution. 

   The Company's contract manufacturers are concentrated among a few 
suppliers and assemblers. The loss of any one supplier or assembler could 
have a significant impact on the Company's financial position or results of 
operations. 

   Sales for 1996 and 1995 resulted primarily from the resale of medical 
devices manufactured by others. 
   
NEWLY ISSUED ACCOUNTING STANDARDS 
    
   Effective 1996, the Company adopted SFAS No. 121, "Accounting for the 
Impairment of Long-Lived Assets and Long-Lived Assets to be Disposed of." 
SFAS No. 121 requires that an entity shall review, long-lived assets and 
certain identifiable intangibles to be held and used, for impairment whenever 
events or changes in circumstances indicate that the carrying amount of an 
asset may not be recoverable. If an asset is identified as impaired, the 
entity shall estimate future cash flows (undiscounted and without interest) 
which are expected to result from the use of the asset and its eventual 
disposition. If the sum of the future cash flows is less than the carrying 
amount of the asset, the entity shall recognize an impairment loss in 
accordance with this pronouncement. The adoption of this statement did not 
have an impact on the Company's financial position and results of operations. 
   
   In October 1995, the Financial Accounting Standards Board issued Statement 
of Financial Accounting Standards No. 123, "Accounting for Stock-Based 
Compensation," which established financial accounting and reporting standards 
for stock based plans. The Statement requires the Company to choose between 
accounting for issuances of stock and other equity instruments to employees 
based on their fair value or to continue to use an intrinsic value based 
method and disclosing the pro forma effects such accounting would have had on 
the Company's net income and earnings per share. The Company has elected to 
use the intrinsic value based method, which does not result in compensation 
cost. Due to the minimal number of options issued in fiscal 1996 and 1995, 
the effects of the adoption are not significant. 
    

RECLASSIFICATIONS 

   Certain reclassifications have been made to conform prior year amounts to 
the current year presentation.

                                                                    $806,885 
                                                                    ========== 
   
   Depreciation expense was $57,733 and $2,814 in fiscal 1996 and 1995, 
respectively. 
    

5. PATENT RIGHTS: 

   
   On June 30, 1994, the Company entered into an exclusive license agreement 
with the estate of an inventor related to two patents for a difficult to 
reuse syringe. Such agreement includes fixed payments aggregating $112,000 
through June, 1997. Thereafter, the Company is required to pay quarterly 
royalty payments of 5% of net sales of product manufactured by Univec under 
the license agreement or 10% of the difference between net 
    

                                     F-9

                         Univec, Inc. and Subsidiary 

          Notes to Consolidated Financial Statements  - (Continued) 

   
sales and purchase price of product manufactured under the license agreement 
by third parties for Univec shall be made. Univec may grant non-exclusive 
sublicenses under the agreement, in which case 10% of any royalties collected 
by Univec would be payable to the inventor's estate. If the manufactured 
product does not use the difficult to reuse syringe of the type discussed in 
the patent, no royalties are due, other than the minimum annual licensing 
fees. 
    

   Patent rights consist of the following: 

Patent rights  ..................................................   $112,000 
Less accumulated amortization ...................................    (40,000) 
                                                                   ----------- 
                                                                    $ 72,000 
                                                                   =========== 

   Amortization expense for fiscal 1996 and 1995 was $16,000, respectively. 

   The Company paid $92,000 through December 31, 1996 in connection with this 
agreement, and the remaining fixed payments of $20,000 are scheduled to 
mature in fiscal 1997. 

6. ACCRUED EXPENSES: 

   Accrued expenses consist of the following: 

Payroll  .......................................................    $ 36,000 
Payroll taxes  .................................................      22,499 
Interest  ......................................................      23,502 
Professional fees ..............................................      45,694 
Royalties  .....................................................      25,000

                                                                    $175,195 
                                                                    ========== 
7. NOTES PAYABLE: 

   On February 9, 1995, the Company entered into a term note agreement with 
an available line of $600,000. This facility is collateralized by the assets 
of the Company and bears interest at a rate of 16%. As of December 31, 1995, 
$540,000 was outstanding under this agreement. During July 1996, the Company 
repaid the outstanding balance. Interest expense for fiscal 1996 and 1995 
approximated $60,600 and $49,000, respectively, in connection with this 
agreement. 

   In December 1995, the Company issued a demand note payable of $125,000. 
The note is collateralized by the assets of the Company and bears an interest 
rate of 12-1/2%. Interest expense for 1996 and 1995 approximated $15,600 and 
$1,300, respectively. The note agreement contains an option to convert the 
note into common shares of the Company at the IPO price (35,715 shares at a 
proposed share price of $3.50). 

   
8. NOTES PAYABLE TO OFFICERS AND STOCKHOLDERS: 

   In September 1996, the Company entered into an agreement to convert the 
outstanding balance of approximately $732,000 owed two officers into notes 
due the earlier of two years following an IPO or September 30, 1999. During 
December 1996, one of the officers converted $56,500 of the indebtedness into 
common shares (16,143 shares, at a proposed share price of $3.50). 

   In December 1996, the Company converted $161,000 of notes payable to 
stockholders into Series A Preferred Stock (see Note 13). The remaining 
$116,373 balance at December 31, 1996 will automatically be converted into 
common shares upon the consummation of an IPO (33,250 shares at a proposed 
share price of $3.50).

9. DUE TO AFFILIATES: 

   Upon founding of the Company in August 1992, pending Univec's obtaining 
its own financing, the Company's costs were funded by Joel Schoenfeld, an 
owner officer of the Company, and JS Associates, and J&B Schoenfeld (together 
with Joel Schoenfeld, the "Affiliates"), each of whose sole stockholder is 
Joel Schoenfeld. These costs, representing research and development, market 
analysis and development and various administrative costs (including office 
salaries and rental of office space), were accrued by Univec as paid by the 
Affiliates. Such costs have been included in the statement of operations 
based on the type of costs incurred to be reimbursed to the Affiliates. The 
related liability has been recorded on the balance sheet as due to 
affiliates. These advances are due on demand and bear interest at a rate of 
8% per annum. Interest expense for fiscal 1996 and 1995 in connection with 
these advances approximated $76,100 and $78,000, respectively. In December 
1996, the Company converted $1,108,342 of these notes to Series A Preferred 
Stock (see Note 13). 

10. BRIDGE NOTE: 

   During December 1996, the Company raised $1,000,000 through a private 
placement of 40 units with each unit consisting of an 8% bridge note in the 
principal amount of $25,000 and warrants to purchase 62,500 shares of common 
stock. Each warrant entitles the holder to purchase one share of common stock 
at an exercise price of $4.50 per share at any time during the period 
commencing November 27, 1997 and ending on November 26, 2001. The net 
proceeds of approximately $820,000 were used for sales and marketing, capital 
expenditures, working capital, and general corporate expenses. 

   These uncollateralized notes are payable upon the earlier of November 27, 
1997 or the consummation of an initial public offering, private placement of 
debt or equity securities resulting in gross proceeds of at least $5,000,000. 
All the warrants issued in connection with the placement were valued at 
$675,000 and will be amortized to interest expense over the expected term of 
the debt. 

11. INCOME TAXES: 
    

   The Company has cumulative losses of $4,253,138 as of December 31, 1996. 
Losses aggregating approximately $1,900,000 which were incurred prior to the 
Company changing its tax status to an S-Corporation would be available should 
the Company return to C-Corporation status. The Company's net operating loss 
for tax purposes differs from the loss for financial reporting purposes as a 
result of certain costs being capitalized and expensed over a five-year 
period for tax purposes. The Company has recorded a full valuation allowance 
against the potential future benefit of such deferred tax assets. 

   Upon closing of the proposed public offering, the Company's income tax 
status as an S corporation will terminate. The Company will convert to a C 
corporation and will be subject to both Federal and state income taxes. 
Accordingly, the Company will record a deferred tax asset of approximately 
$760,000 resulting from net operating loss carryforwards and a corresponding 
valuation allowance of approximately $760,000. Any income tax adjustment 
required as a result of the conversion will be reflected in the period C 
corporation status becomes effective. 

   In addition, the undistributed losses of the S corporation through the 
date of consummation of the offering will be reclassified to additional 
paid-in capital. 

   
12. COMMITMENTS: 

   On January 1, 1995, the Company entered into an exclusive license 
agreement with two inventors related to a patent for an insertable element 
which prevents reuse of a disposable syringe. To maintain this license 
agreement in force, the Company is required to pay an annual minimum 
licensing of $10,000. In order for the agreement to remain exclusive, 
exclusivity payments of $25,000 in 1996 and 1995 and $50,000 annually 
thereafter, are required to be made. In both fiscal 1996 and 1995, $35,000 
was charged to operations in connection

with this agreement. Under the license agreement, royalty payments of 2% of 
net sales of product manufactured and 25% of sublicense royalties received 
shall be made for products which use a modification of the specific 
insertable element as shown and described in the licensed patent rights. 
Royalty payments of 6% of net sales of product manufactured and 40% of 
sublicense royalties received shall be made for products that use the 
specific insertable element. If the manufactured product does not use the 
difficult to reuse syringe of the type discussed in the patent, no royalties 
are due, other than the minimum annual licensing fees. 

   On February 28, 1996, the Company entered into an exclusive license 
agreement with an inventor related to a patent for a difficult to reuse 
hypodermic syringe. The Company is required to pay a royalty advance of 
$10,000, which will be applied towards future royalties. As of December 31, 
1996, $10,000 was charged to operations in connection with this agreement. In 
addition, royalty payments of 2% of net sales of product manufactured and 10% 
of sublicense royalties received shall be made for products which use a 
modification of the specific embodiment as shown and described in the 
licensed patent rights. Royalty payments of 6% of net sales of product 
manufactured and 25% of sublicense royalties received shall be made for 
products that use the specific embodiment. If the manufactured products which 
use a modification of the difficult to reuse syringe of the type discussed in 
the patent, no royalties are due, other than the minimum annual licensing 
fees. 

   On March 25, 1996, the Company entered into an exclusive license agreement 
with an inventor related to a patent for a difficult to reuse hypodermic 
syringe. The Company was required to pay $10,000 upon the execution of the 
agreement and an additional two payments of $20,000 on the six-month and 
one-year anniversaries to maintain the agreement. In connection with this 
agreement, the Company has also agreed to pay $15,000 upon signing of a 
separate consultation agreement and $39,000 over the next twenty months for 
consultation assistance in the development of manufacturing and assembly 
equipment. As of December 31, 1996, $72,000 was charged to operations. In 
addition, royalty payments of 2% of net sales of product manufactured and 10% 
of sublicense royalties received shall be made for products which use a 
modification of the specific embodiment as shown and described in the 
licensed patent rights. Royalty payments of 7% of net sales of product 
manufactured and 25% of sublicense royalties shall be made for products that 
use the specific embodiment. If the manufactured product does not use the 
difficult to reuse syringe of the type discussed in the patent, no royalties 
are due, other than the minimum annual licensing fees. 

   On May 30, 1996, the Company entered into a five-year supply and licensing 
agreement with a manufacturer. The supply agreement requires the manufacturer 
to supply Univec with approximately 50,000,000 syringe components per year. 
In connection with this supply agreement, the manufacturer sold a production 
mold and inserts to Univec for nominal consideration, and subsequently leased 
back the equipment. Under this lease, the lessee is required to make payments 
over three years approximating $1,946,000 to Univec. In July 1996, Univec 
assigned its rights to the last 34 lease payments to an unrelated corporation 
for approximately $1.6 million. Certain stockholders of the Company have 
agreed to pay the manufacturers up to $1,000,000 (less $0.14925 for each 
dollar paid by the Company under the agreement) if Univec does not purchase 
$6,700,000 of products from the manufacturer over the first three years of 
the agreement. 
    

   Simultaneous with the supply agreement, the Company granted the 
manufacturer the option to license the Company's product providing the 
manufacturer the right to manufacture and sell the Company product to certain 
segments of the market for a royalty of 5% of sales of the licensed product. 
Unearned income in connection with these agreements will be recognized in 
income upon the sale of the Company's product supplied by the manufacturer. 
No amounts have been recognized in income in 1996. 

   
   The Company has executed employment agreements, expiring through March 
2000, with certain executive officers of the Company. Future payments under 
such agreements are as follows: 
    

             1997 ....................................    $282,000 
             1998 ....................................     192,000

          Notes to Consolidated Financial Statements  - (Continued) 

   The Company leases office space under an operating lease that expires in 
December 1998 from a stockholder and officer of the Company. Minimum future 
rentals under this lease are $28,704 through fiscal 1998. Rent expense for 
fiscal 1996 and 1995 was $27,600, respectively. 

13. EQUITY: 
    

   The following share and per share amounts have been restated to reflect 
the reorganization as described in Note 1. 

   
   In February 1995, the Company's board of directors and stockholders 
approved the sale of 33,360 shares of the common stock to a stockholder of 
the Company for an aggregate purchase price of $300,000. The individual also 
received the option to purchase 22,236 additional shares of common stock at 
the initial public offering price. The agreement expires on February 22, 
1999. 
    

   In June 1995, the Company's board of directors and stockholders approved a 
Share Option Agreement between the Company and an individual. The individual 
has the option to purchase 33,436 shares of the common stock at the initial 
public offering price. As of December 31, 1996, no options were exercised. 
The agreement expires on June 30, 1998. 

   In December 1995, a stockholder of the Company gave 10,256 shares of his 
common stock to a creditor of the Company to satisfy a liability for services 
rendered. The Company has recorded a $35,000 contribution to paid-in capital. 

   On December 14, 1996, the Company issued 7,143 shares at a price of $3.50 
per share in exchange for the cancellation of $25,000 of indebtedness payable 
to a consultant for the Company. 

   
   In connection with the reorganization in October 1996 (see Note 1), the 
Company authorized the issuance of 1,269 shares of Series A Preferred Stock 
to certain officers in exchange for the cancellation of notes due to 
affiliate and payable to stockholders of $1,269,000. 
    

   Series A preferred shares are entitled to receive, prior to the payment of 
cash dividends of the common stock, cumulative dividends at a rate of $80 per 
share per annum and may be redeemed at the option of the Company, at $1,000 
per share (aggregate liquidation preference of $1,269,000). In addition, 
preferred stockholders are entitled to a liquidation preference of $1,000 per 
share, plus accrued and unpaid dividends. Each share of Series A Preferred 
Stock is convertible at the earlier of two years following an IPO or 
September 30, 1999 into 222.22 shares of common stock ($4.50 per share). 
Holders of these shares have no voting rights. 

   
14. STOCK OPTION PLAN: 

   The Board of Directors has adopted, and the Company's stockholders have 
approved, the 1996 Stock Option Plan (the "Plan"). The Plan is to be 
administered by the Board of Directors or a committee thereof. Pursuant to 
the Plan, options to purchase 4,709,219 shares of common stock may be granted 
to directors, employees (including officers) and consultants to the Company 
(collectively, "Plan participants"). The Plan authorizes the issuance of 
incentive stock options ("ISOs"), as defined in Section 422A of the Internal 
Revenue Code of 1986, as amended, and non-qualified stock options ("NQSOs", 
and together with ISOs, "Options"). Consultants and directors who are not 
also employees of the Company are eligible for grants of only NQSOs. The 
exercise price of each ISO may not be less than 100% of the fair market value 
of the common stock at the time of grant, except that in the case of a grant 
to an employee who owns 10% or more of the outstanding stock of the Company 
or a subsidiary or parent of the Company (a "10% Stockholder"), the exercise 
price may not be less than 110% of the fair market value on the date of 
grant. The aggregate fair market value of the shares covered by ISOs granted 
under the Plan that become exercisable by a Plan participant for the first 
time in any calendar year is subject to a $100,000 limitation. The exercise 
price of each NQSO is determined by the Board, or committee

          Notes to Consolidated Financial Statements  - (Continued) 

thereof, in its discretion; provided that NQSO granted a 10% Stockholder be 
no less than 110% of the fair market value on the date of grant. On December 
14, 1996, the Company granted ISOs to an officer of the Company to purchase 
20,513 shares of common stock at an exercise price of $3.50 per share. As of 
December 31, 1996, 16,143 options were exercised. 

   
   The Company has set aside Options to purchase 4,500,000 shares of common 
stock based on the criteria listed below. These Options will become 
exercisable commencing upon the earlier of (x) nine years after the effective 
date of the option, or (y) two years after the effective date of the option, 
provided that in the case of clause (y), the Company shall have obtained (i) 
at least $30,000,000 in gross revenues and after tax net income of at least 
$2,000,000 in the second full fiscal year following the effective date, or 
(ii) at least $45,000,000 in gross revenues and $3,000,000 in after-tax net 
income in the third full fiscal year following the effective date, or (iii) 
at least $60,000,000 in gross revenues and $4,000,000 in after-tax net income 
in the fourth full fiscal year following the effective date. 

15. SUBSEQUENT EVENT: 

   In January and March 1997, the Company authorized the issuance of 650 
shares of Series A 8% Cumulative Convertible Preferred Stock to certain 
shareholders of common stock in exchange for amounts due of $650,000.

     PRELIMINARY PROSPECTUS, SUBJECT TO COMPLETION, DATED MARCH 14, 1997 
                                 UNIVEC, INC. 
                     2,533,436 SHARES OF COMMON STOCK AND 
             2,500,000 REDEEMABLE COMMON STOCK PURCHASE WARRANTS 
    
   This Prospectus relates to 2,533,436 shares of common stock, par value 
$.001 per share (the "Common Stock") of UNIVEC, Inc. (the "Company"), and 
2,500,000 redeemable common stock purchase warrants (the "Warrants") that may 
be sold by the selling securityholders named herein (the "Selling 
Securityholders"). See "Selling Securityholders". The 2,500,000 Warrants 
offered hereby were issued in connection with a bridge financing completed by 
the Company in December 1996. Of the 2,533,436 shares of Common Stock offered 
hereby, 2,500,000 shares are issuable upon exercise of the Warrants and 
33,436 shares are issuable upon exercise of options. 
   
   Each Warrant entitles the registered holder thereof to purchase one share 
of Common Stock at an exercise price of $4.50 per share, subject to 
adjustment in certain events, at any time during the period commencing 
__________, 1999 [two years after the date upon which the Registration 
Statement of which this Prospectus forms a part is declared effective by the 
Securities Exchange Commission (the "Effective Date")] and expiring on 
____________, 2002 [the fifth anniversary of the Effective Date]. The 
Warrants are subject to redemption by the Company at $.05 per Warrant at any 
time commencing _______________, 1999 [two years after the Effective Date], 
with the prior written consent of Maidstone Financial, Inc. ("Maidstone" or 
the "Representative"), on not less than 30 days prior written notice to the 
holders of the Warrants, provided the closing bid price of the Common Stock 
has been at least $8.00 for 20 consecutive trading days ending on the third 
day prior to the date on which the Company gives notice of redemption. The 
Warrants will be exercisable until the close of business on the day 
immediately preceding the date fixed for redemption. The Company has applied 
for quotation of the Common Stock and the Warrants on The Nasdaq SmallCap 
Market under the trading symbols "UNVC" and "UNVCW", respectively. See 
"Description of Securities -- Warrants." 

   The Selling Securityholders may sell Warrants and shares of Common Stock 
from time to time directly to purchasers, or through broker-dealers who may 
receive compensation in the form of commissions or discounts from the Selling 
Securityholders or purchasers. Sales of Warrants and shares of Common Stock 
may be effected by broker-dealers in ordinary brokerage transactions or block 
transactions on The Nasdaq SmallCap Market, through sales to one or more 
dealers who may resell as principals, in privately negotiated transactions or 
otherwise, at the market price prevailing at the time of sale, a price 
related to such prevailing market price or at a negotiated price. Usual and 
customary or specifically negotiated brokerage fees may be paid by the 
Selling Securityholders in connection therewith. To the Company's knowledge, 
none of the Selling Securityholders has entered into any underwriting 
arrangements for the sale of such securities. The Company has offered, by 
separate Prospectus dated the date hereof, 1,500,000 shares of Common Stock 
and 2,225,000 Common Stock Purchase Warrants having terms identical to the 
Warrants offered hereby for which Maidstone acted as the Representative of 
the Underwriters (the "Offering" or the "IPO"). Each of the Selling 
Securityholders has agreed not to offer or sell the Warrants or shares of 
Common Stock offered hereby (except under certain circumstances in connection 
with a third party tender offer for the Common Stock) until 24 months after 
the Effective Date, without the prior written consent of the Representative, 
which may be granted or withheld in the sole and absolute discretion of the 
Representative. The Representative has agreed that it will not consent to the 
sale of any of the securities offered hereby prior to the expiration of the 
45-day period commencing on the date of the closing of the IPO during which 
the Underwriters may exercise an option to purchase from the Company up to an 
additional 15% of the shares of Common Stock and/or Common Stock Purchase 
Warrants offered in the IPO to cover over-allotments, if any (the 
"Over-Allotment Option"), or such earlier date upon which the Over-Allotment 
Option is fully exercised.

based upon information available to the Company as of the date hereof, the 
number of shares of Common Stock beneficially owned, the number of Warrants 
and/or shares of Common Stock to be sold, and the number of outstanding

Effective Date, the Bridge Warrants will convert automatically into the 
Warrants. The Bridge Notes will be paid out of the net proceeds of the IPO. 
Although there can be no assurance that the Selling Securityholders will sell

(1) Unless otherwise indicated, each person has sole investment and voting

    outstanding shares held by each Selling Securityholder, any security 
    which such person has the right to acquire within 60 days after the

    the percentage ownership for such person, but is not deemed to be 
    outstanding for the purpose of computing the percentage ownership of any

                             PLAN OF DISTRIBUTION 
   
   Selling Securityholders may sell the Warrants and shares of Common Stock 
offered hereby from time to time directly to purchasers, or through 
broker-dealers who may receive compensation in the form of commissions or 
discounts from the Selling Securityholders or purchasers. Sales of Warrants 
and shares of Common Stock may be effected by broker-dealers in ordinary 
brokerage transactions or block transactions on The Nasdaq SmallCap Market, 
through sales to one or more dealers who may resell as principals, in 
privately negotiated transactions or otherwise, at the market price 
prevailing at the time of sale, a price related to such prevailing market 
price or at a negotiated price. Usual and customary or specifically 
negotiated brokerage fees may be paid by the Selling Securityholders in 
connection therewith. To the Company's knowledge, none of the Selling 
Securityholders have entered into any underwriting arrangements for the sale 
of such securities. Each of the Selling Securityholders has agreed not offer 
or sell the Warrants or shares of Common Stock offered hereby (except under 
certain circumstances in connection with a third party tender offer for the 
Common Stock) until 24 months after the Effective Date, without the prior 
written consent of the Representative, which may be granted or withheld in 
the sole and absolute discretion of the Representative. The Representative 
has agreed that it will not consent to the sale of any of the securities 
offered hereby prior to the expiration of the 45-day period commencing on the 
date of the closing of the IPO during which the Underwriters may exercise the 
Over-Allotment Option, or such earlier date upon which the Over-Allotment 
Option is fully exercised. 
    

   The Selling Securityholders may be deemed to be "underwriters" within the 
meaning of the Securities Act and any profits realized by them may be deemed 
to be underwriting commissions. Any broker-dealers that participate in the 
distribution of the Warrants or shares of Common Stock also may be deemed to 
be "underwriters", as defined in the Securities Act, and any commissions or 
discounts paid to them, or any profits realized by them upon the resale of 
any securities purchased by them as principals, may be deemed to be 
underwriting commissions or discounts under the Securities Act. The sale of 
the Warrants and shares of Common Stock by the Selling Securityholders is 
subject to the prospectus delivery and other requirements of the Securities 
Act. 

   The Warrants and shares of Common Stock offered hereby have been 
registered pursuant to registration rights granted to the Selling 
Securityholders. All costs, expenses and fees in connection with the 
registration of the Warrants and shares of Common Stock offered by the 
Selling Securityholders will be borne by the Company. The Selling 
Securityholders are responsible for the payment of brokerage commissions and 
discounts incurred in connection with the sale of their Warrants and shares 
of Common Stock. The Company has agreed to indemnify the Selling 
Securityholders against certain liabilities, including liabilities under the 
Securities Act. 

   
   Under the Exchange Act and the regulations thereunder, any person engaged 
in a distribution of the Warrants and Common Stock offered by this Selling 
Securityholder Prospectus may not simultaneously engage in market-making 
activities with respect to the Warrants or Common Stock during the applicable 
"cooling off" period prescribed by Rule 101 of Regulation M prior to the 
commencement of such distribution. In addition, and without limiting the 
foregoing, the Selling Securityholders will be subject to applicable 
provisions of the Exchange Act and the rules and regulations thereunder 
including, without limitation, Rule 102 of Regulation M, which provisions may 
limit the timing of purchases and sales of Warrants and Common Stock by the 
Selling Securityholders. 
    

   To the extent required, the Company will use its best efforts to file, 
during any period in which offers or sales of Warrants and/or shares of 
Common Stock are being made by or on behalf of the Selling Securityholders, 
one or more amendments or supplements to this Selling Securityholder 
Prospectus which describe any material information with respect to the plan 
of distribution not previously disclosed herein, including the name or names 
of any underwriters, broker-dealers or agents, if any, the purchase price 
paid by any underwriter for Warrants and/or shares of Common Stock purchased 
from a Selling Securityholder, and any discounts, commissions or concessions 
allowed or reallowed or paid to broker-dealers.

                                   PART II 
                    INFORMATION NOT REQUIRED IN PROSPECTUS 

ITEM 24. INDEMNIFICATION OF DIRECTORS AND OFFICERS 

   
   Article 7 of the Registrant's Certificate of Incorporation, in accordance 
with Section 145 of the DGCL, provides that directors and officers shall be 
indemnified against expenses (including attorneys' fees), judgments, fines 
and amounts paid in settlement in connection with specified actions, suits or 
proceedings, whether civil, criminal, administrative or investigative (other 
than an action by or in the right of the corporation -- a "derivative 
action") if they acted in good faith and in a manner they reasonably believed 
to be in or not opposed to the best interests of the corporation, and, with 
respect to any criminal action or proceeding, had no reasonable cause to 
believe their conduct was unlawful. A similar standard of care is applicable 
in the case of derivative actions, except that indemnification only extends 
to expenses (including attorneys' fees) incurred in connection with the 
defense or settlement of such an action. Moreover, the DGCL requires court 
approval before there can be any indemnification where the person seeking 
indemnification has been found liable to the corporation. 
    

   Article 7 of the Registrant's Certificate of Incorporation further 
provides that directors and officers are entitled to be paid by the 
Registrant the expenses incurred in defending the proceedings specified above 
in advance of their final disposition, provided that such payment will only 
be made upon delivery to the Registrant by the indemnified party of an 
undertaking to repay all amounts so advanced if it is ultimately determined 
that the person receiving such payments is not entitled to be indemnified. 

   Article 7 of the Registrant's Certificate of Incorporation provides that a 
person indemnified under Article 7 of the Certificate of Incorporation may 
contest any determination that a director, officer, employee or agent has not 
met the applicable standard of conduct set forth in the Certificate of 
Incorporation by petitioning a court of competent jurisdiction. 

   Article 7 of the Registrant's Certificate of Incorporation provides that 
the right to indemnification and the payment of expenses incurred in 
defending a proceeding in advance of its final disposition conferred in the 
Article will not be exclusive of any other right which any person may have or 
acquire under the Certificate of Incorporation, or any statute or agreement, 
or otherwise. 

   Finally, Article 7 of the Registrant's Certificate of Incorporation 
provides that the Registrant may maintain insurance, at its expense, to 
reimburse itself and directors and officers of the Registrant and of its 
direct and indirect subsidiaries against any expense, liability or loss, 
whether or not the Registrant would have the power to indemnify such persons 
against such expense, liability or loss under the provisions of Article 7 of 
the Certificate of Incorporation. The Registrant has applied for such 
insurance, and expects to have such insurance in effect on the date this 
Registration Statement is declared effective by the Commission. 

   Article 8 of the Registrant's Certificate of Incorporation eliminates the 
personal liability of the Registrant's directors to the Registrant or its 
stockholders for monetary damages for breach of their fiduciary duties as a 
director to the fullest extent provided by Delaware law. Section 102(b)(7) of 
the DGCL provides for the elimination off such personal liability, except for 
liability (i) for any breach of the director's duty of loyalty to the 
Registrant or its stockholders, (ii) for acts or omissions not in good faith 
or which involve intentional misconduct or a knowing violation of law, (iii) 
under Section 174 of the DGCL or (iv) for any transaction from which the 
director derived any improper personal benefit. 

   
   Reference is made to Section 1.1 of the Underwriting Agreement between the 
Registrant and the Underwriters, filed as Exhibit 1.1 to this Registration 
Statement, which provides for indemnification by the Underwriters of the 
Registrant and the directors and officers of the Registrant under certain 
limited circumstances. 
    

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

ITEM 26. RECENT SALE OF UNREGISTERED SECURITIES 

   During the past three years, the Registrant has sold securities to a 
limited number of persons, as described below. Except as indicated, there 
were no underwriters involved in the transactions and there were no 
underwriting discounts or commissions paid in connection therewith. The 
purchasers of securities in each such transaction represented their intention 
to acquire the securities for investment only and not with a view to or for 
sale in connection with any distribution thereof and appropriate legends were 
affixed to the certificates for the securities issued in such transactions. 
All purchasers of securities in each such transaction had adequate access to 
information about the Registrant, and in the case of transactions exempt from 
registration under Section 4(2) of the Securities Act, were sophisticated 
investors. 

   1. Between February 28, 1995 and June 30, 1995, the Registrant issued and 
sold to John Frank, a director of the Registrant, an aggregate of 33,360 
shares of Common Stock for a purchase price of $300,000 ($8.93 per share). In 
connection therewith, the Registrant granted Mr. Frank an option to purchase 
an additional 22,236 shares of Common Stock at an exercise price of $77,826

ITEM 28. UNDERTAKINGS 

(a) Rule 415 Offering
 
    The undersigned small business issuer hereby undertakes that it will: 

       (1) File, during any period in which it offers or sells securities, a 
           post-effective amendment to this registration statement to:
 
          (i) Include any prospectus required by section 10(a)(3) of the 
              Securities Act.

          (ii) Reflect in the prospectus any facts or events which, 
               individually or together, represent a fundamental change in 
               the information set forth in the registrant statement. 
               Notwithstanding the foregoing, any increase or decrease in 
               volume of securities offered (if the total dollar value of 
               securities offered would not exceed that which was registered) 
               and any deviation from the low or high end of the estimated 
               maximum offering range may be reflected in the form of 
               prospectus filed with the Commission pursuant to Rule 424(b) 
               if, in the aggregate, the changes in volume and price 
               represent no more than a 20% change in the maximum aggregate 
               offering price set forth in the "Calculation of Registration 
               Fee" table in the effective registration statement. 

          (iii) Include any additional or changed material information on the 
                plan of distribution. 

       (2) For determining any liability under the Securities Act, treat each 
           post-effective amendment as a new registration statement relating 
           to the securities offered, and the offering of such securities at 
           that time to be the initial bona fide offering thereof.
 
       (3) File a post-effective amendment to remove from registration any of 
           the securities that remain unsold at the end of the offering. 

(d) Equity Offerings by Non-Reporting Small Business Issuers 
    The undersigned small business issuer hereby undertakes that it will 
    provide 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. 

                                      II-4
<PAGE>

(e) Request for Acceleration of Effective Date 

    Insofar as indemnification for liabilities arising under the Securities 
    Act may be permitted to directors, officers and controlling persons of 
    the small business issuer pursuant to the foregoing provisions, or 
    otherwise, the small business issuer has been advised that in the opinion 
    of the Commission such indemnification is against public policy as 
    expressed in the Securities Act and is, therefore, unenforceable. In the 
    event that a claim for indemnification against such liabilities (other 
    than the payment by the small business issuer of the expenses incurred or 
    paid by a director, officer, or controlling person of the small business 
    issuer 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 small business issuer 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. 

(f) Rule 430A Offering 

       (1) For determining any liability under the Securities Act, treat the 
           information omitted from the form of prospectus filed as part of 
           this registration statement in reliance upon Rule 430A and 
           contained in a form of prospectus filed by the small business 
           issuer 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. 

       (2) For determining any liability under the Securities Act, treat each 
           post-effect amendment that contains a form of prospectus as a new 
           registration statement for the securities offered in the 
           registration statement, and that offering of the securities at that 
           time as the initial bona fide offering of those securities.

sixty (60) days from date of shipment.  Thereafter, payment terms are net thirty
(30) days from date of shipment.

     4(b)  Sherwood-D&G  shall  have the right to revise the prices set forth in
Exhibit  A not more  often  than  once  during  any  twelve  (12)  month  period
commencing  twelve (12) months after the  Commencement  Date, by giving Customer
thirty (30) days  written  advance  notice.  Such  revisions  in price shall not
exceed the  actual  changes in the cost to  Sherwood-D&G  for parts,  materials,
labor and overhead  directly related to the manufacture,  packaging and labeling
of the Products,  utilizing generally accepted accounting principles,  but in no
event will any price  increase  for any Product  exceed five percent (5%) in any
twelve (12) month period.  Customer may, at its option,  request verification of
such  increases  by  independent   certified  public   accountants,   reasonably
acceptable  to  Sherwood-D&G.  In no event shall any such upward price  revision
take into account any amount with respect to any lease payments or  amortization
charges or any  increase in  maintenance,  overhead or any other cost or expense
relating to the plunger mold leased by  Sherwood-D&G  from  Customer to make the
Plunger.

its successors and assigns shall defend,  indemnify and save harmless  Customer,
its employees, officers, subsidiaries and affiliated companies, their successors

SECTION 4. LICENSES GRANTED

     4(a)  Licensor  hereby  grants to Sherwood  and Sherwood  hereby  accepts a
paid-up  non-exclusive license to utilize the Licensed Know-how in perpetuity to
make,  have made for it,  use and/or  sell the  Licensed  Invention,  and/or the
Licensed Products in the Licensed Territory.

     4(b)  Licensor  hereby  grants to Sherwood  and Sherwood  hereby  accepts a
non-exclusive  license  under the  Licensed  Patent  Rights and a  non-exclusive
sub-license  under the Movern Patent to make,  have made for it, use and/or sell
the Licensed Invention and/or the Licensed Products in the Licensed Territory.

     4(c)  Sherwood  hereby  grants to Licensor  and Licensor  hereby  accepts a
perpetual,  fully paid, royalty free,  non-exclusive license to make, use and/or
sell  the  Sherwood   Developments  or  products   incorporating   the  Sherwood
Developments.

SECTION 5. ROYALTIES

     5 (a) As  consideration  for the  non-exclusive  license  herein granted in
Paragraph  4(b)  hereof,  Sherwood  agrees to pay to Licensor an earned  royalty
equal to five percent (5 %) of Net Sales of Licensed  Products invoiced for sale
by Sherwood.  Such royalty payment shall be mailed to Licensor within sixty (60)
days (the "Royalty  Payment Date") after the end of each six-month period ending
June 30 and December 31 (each a "Royalty  Reporting Period") of each year (each,
a "Royalty Year") during the term of this Agreement.

     5 (b) It is understood  that this  Agreement  includes no obligation on the
part of Sherwood,  expressed or implied,  to commercialize  Licensed Product, to
sell any specific number of Licensed Products,  or to do so in any set period of
time.  However, if Sherwood shall either (i) fail to introduce to the market and
make  commercial  sales of  Licensed  Product  within  two (2)  years  from  the
effective date of this Agreement,  or (ii) fail to sell any Licensed Product for
a  continuous  period  of five (5)  years at any  time  during  the term of this
Agreement, then in either event, Licensor shall have the option, upon sixty (60)
days written notice to Sherwood, to terminate this Agreement.

     5 (c) In the event that any of the Licensed  Patent  Rights in the Licensed
Territory is finally declared abandoned,  lapsed,  unenforceable or, in whole or
in part,  invalid  to the extent  that no claim of the  Licensed  Patent  Rights
survives  which  claims  Licensed  Products  made and/or sold by Sherwood or any
Related Company within the Licensed Territory,  then thereafter,  Sherwood shall
not be  required to pay any royalty  under this  Agreement.  In the event that a
valid,  enforceable  patent  claiming  Licensed  Products  made  and/or  sold by
Sherwood  or any Related  Company in the  Licensed  Territory  is not granted to
Licensor  within  three (3) years after the  effective  date of this  Agreement,
then,  unless otherwise  mutually agreed in writing or unless and until a valid,
enforceable  patent  claiming  Licensed  Products  is  subsequently  granted  to
Licensor  within the  Licensed  Territory,  Sherwood  shall  thereafter  only be
required to pay to Licensor


                                       5
<PAGE>


one-half (1/2) the applicable  royalty set forth in Paragraph 5(a) hereof on the
Net  Sales  in  the  Licensed  Territory  of  products  previously  meeting  the
definition of Licensed  Products under Paragraph 1 (d) hereof for the remainder,
if any,  of a period of three (3) years from the date of first sale of  Licensed
Products by Sherwood or Related  Company.  Sherwood and any  sublicensees  shall
thereafter be deemed to have a fully paid-up, royalty-free non-exclusive license
under the Licensed Patent Rights within the Licensed Territory, unless and until
a valid,  enforceable patent claiming Licensed Products is subsequently  granted
to Licensor, in which event the obligation to pay a full royalty under Paragraph
5(a) hereof for the future shall be  reinstated.

     5 (d)  Sherwood  shall have the right to deduct  from any  payments  due to
Licensor under Paragraphs 5(a), 5(b) and/or 5(c) hereof,  the full amount of any
payments  required to be made and actually  made by Sherwood with respect to any
rights under the Movern  Patents or the Movern  License in  connection  with the
Licensed Invention, the Licensed Patent Rights or this Agreement.

SECTION 6. ROYALTY CALCULATION, REPORTS AND RECORDS

 6 (a) Sherwood agrees,  and will require any Related Companies to agree,
to keep true and  accurate  records  adequate to establish  any royalty  payable
under this Agreement and to permit an independent  certified  public  accountant
selected by Licensor and  reasonably  acceptable to Sherwood,  to inspect,  on a
confidential  basis and at  Licensor's  expense,  said records once  annually at
reasonable times upon reasonable  notice,  but only within a period of three (3)
years after the last day of the Royalty  Reporting  Period to which such records
relate. On the Royalty Payment Date, Sherwood shall provide to Licensor a report
(a "Royalty Report") for each Royalty Reporting Period, setting forth the earned
royalty  due and payable on Net Sales,  if any,  of Sherwood  and/or any Related
Companies of Licensed Products during such Royalty Reporting Period, accompanied
by payment of all amounts  shown to be so due and payable,  if any.

     6 (b) Earned  royalty,  as provided in Paragraph 5(a) hereof,  shall accrue
upon the first sale of Licensed Product to an unrelated third-party distributor,
retailer or end user.

     6 (c) Only a single royalty under Paragraph 5(a) hereof shall be payable to
Licensor for each specific unit of Licensed Product  regardless of the number of
countries in which manufacture,  importation, sale, resale and/or use is made by
Sherwood,  any Related Companies and/or any direct or indirect customer thereof.
Nothing herein is intended nor shall it be construed to grant Sherwood any right
to sell or export or  manufacture  for sale to any place  outside  the  Licensed
Territory.  Each Royalty  Report shall contain a  certification  that no sale of
Licensed  Product was made outside the Territory by Sherwood  during the Royalty
Reporting Period to which such Royalty Report relates.

     6 (d)  All  taxes,  assessments  and  fees  of  any  nature  levied  by any
governmental  entity in the Licensed  Territory of this Agreement on the sale of
Licensed Products by Sherwood, or any Related Company shall be paid by Sherwood,
or any Related Company for its account. However,


                                       6
<PAGE>


if an income or other tax is levied on the  recipient of any royalty  under this
Agreement by any governmental entity and is legally required to be withheld from
the payment of royalty  from  Sherwood or from any Sherwood  sublicensee  and/or
Related Company to Sherwood, such tax shall be paid by Sherwood, its sublicensee
and/or Related  Company for the account of Licensor,  in which event an official
receipt  will be secured  evidencing  such  payment,  the receipt  forwarded  to
Licensor, and the amount of such tax deducted from royalty paid to Licensor.

     6(e) The  provisions  herein as to payment of royalties  shall not apply to
Licensed  Products  embodying  only the subject matter of claims of the Licensed
Patent Rights which have become  abandoned,  lapsed,  expired or which have been
finally declared invalid or unenforceable.

SECTION 7. PATENT ENFORCEMENT AND DEFENSE

     7(a)  If  Sherwood  obtains  notice  or  knowledge  that a third  party  is
infringing  or  misappropriating  any  patent,  trademark,  copyright  or  other
proprietary  rights  with  respect to the  Licensed  Patent  Rights,  the Movern
Patent, the Licensed Invention or the Licensed Products, Sherwood shall promptly
notify  Licensor of such  infringement or  misappropriation.  Sherwood agrees to
cooperate with Licensor in the conduct of any  litigation  which Licensor or its
licensors  may  elect  to  undertake  with  respect  to  such   infringement  or
misappropriation.  Sherwood  shall have the right but not the  obligation  to be
represented in such litigation by its own counsel at its own cost and expense.

     7(b)  Licensor  shall  not be  obligated  to  undertake  by  litigation  or
otherwise the collection of any claim against any person for loss of, damage to,
or  governmental  taking  of  the  Licensed   Invention,   the  Licensed  Patent
Application,  the Licensed Patent Rights or the Licensed Products,  but Licensor
will cooperate with Sherwood at Sherwood's  expense if Sherwood elects to pursue
such claims.

     7(c) Licensor shall  indemnify and hold Sherwood  harmless from and against
any  liabilities,   losses,  damages,  expenses  (including  without  limitation
reasonable  attorneys' fees and expenses),  causes of action,  suits, claims, or
judgments  asserted by third  parties (a "Third Party Claim")  against  Sherwood
arising  out  of a  Third  Party  Claim  with  respect  to the  infringement  or
misappropriation of a patent or other proprietary rights,  which may be asserted
by such third party, because of Sherwood's making, using or selling the Licensed
Invention or the Licensed  Products pursuant to and in accordance with the terms
and conditions of this Agreement, provided that Sherwood shall give Licensor (i)
prompt written notice of the institution or the assertion of a Third Party Claim
for which  indemnity  is or will be  claimed  hereunder  and (ii) to the  extent
permitted by law, the opportunity to take over, control,  settle and defend such
Third Party Claim, at the sole expense of Licensor and with counsel  selected by
Licensor. Sherwood has the right but not the obligation to be represented in any
such Third Party Claim by its own counsel, at its own cost and expense, provided
that such right does not prejudice the right of Licensor to take over,  control,
settle and defend  such Third  Party  Claim to the extent  permitted  by law. If
making, using or selling the Licensed


                                        7

<PAGE>


Invention or the Licensed  Products,  or part thereof is enjoined for any reason
whatsoever during the term of this Agreement,  Licensor has the right at its own
expense to (i) procure for Sherwood the right to continue to make, have made for
it, use and/or sell the Licensed  Invention and the Licensed  Products,  or part
thereof  which is the  subject of such  injunction,  or (ii) to  terminate  this
Agreement without further  obligation of either party to the other. This Section
7 contains  Sherwood's sole and exclusive remedy and Licensor's only obligations
with  respect  to the  infringement  or  misappropriation  of a patent  or other
proprietary  right which may be asserted by an owner thereof or any other person
having an interest therein.

     7(d) Licensor  shall not  indemnify  Sherwood,  hold  Sherwood  harmless or
defend  Sherwood  in respect of any claim of  infringement  or  misappropriation
where such infringement or misappropriation is the result of any modification or
change in the Licensed Invention or Licensed Products (including but not limited
to the Sherwood  Developments) which departs in any manner from the terms of the
Licensed Patent Rights.

SECTION 8. PATENT NOTICE MARKING

     Sherwood  shall,  and  shall  require  each  Related  Company,  to mark all
Licensed   Products  with  the  number  of  any   applicable   patent  or  other
identification  of the Licensed  Patent Rights in accordance with the provisions
of 35 U.S.C. ss.287.

SECTION 9. FORCE MAJEURE

     Neither party to this Agreement shall be responsible to the other party for
nonperformance  or delay in  performance  of any  terms  or  conditions  of this
Agreement  due to acts  of  God,  acts of  governments,  wars,  riots,  strikes,
accidents in  transportation,  or other causes beyond the reasonable  control of
the parties. Failure to pay money shall not be excused under this Section.

SECTION 10. TERM OF AGREEMENT

     Unless this  Agreement  shall be terminated by either party pursuant to the
provisions  hereof,  this Agreement  shall remain in force and effect during the
pendency and until the expiration of the  last-to-expire  of the Licensed Patent
Rights in the  Licensed  Territory,  at which time this  Agreement  will expire.
However,  Sherwood  and any  Related  Companies  shall  thereafter  have a fully
paid-up,  royalty-free  non-exclusive  license  to make,  have made for it,  use
and/or  sell the  Licensed  Invention  and any other  invention  claimed  in the
Licensed Patent Rights without limitation.

SECTION 11. TERMINATION

     11 (a) In the event that either  party hereto shall fail to comply with any
of its material  obligations  under this  Agreement  after the other party shall
have given thirty (30) days  written  notice of such failure to the first party,
which notice shall fully specify the obligation with which


                                       8


<PAGE>


the first  party has not  complied,  then the other  party,  by further  written
notice to the first party, may terminate this Agreement.

     11(b) All rights and licenses  granted under or pursuant to this  Agreement
by Licensor to Sherwood  are, and shall  otherwise be deemed to be, for purposes
of Section 365(n) of Title 11 U.S. Code (the  "Bankruptcy  Code"),  licenses and
rights to "intellectual property" as defined under Section 101 of the Bankruptcy
Code. The parties agree that  Sherwood,  as a licensee of such rights under this
Agreement,  shall retain and may fully  exercise all of its rights and elections
under the Bankruptcy Code.  Licensor shall also have the right to terminate this
Agreement in the event of the filing of a voluntary or  involuntary  petition of
bankruptcy of Sherwood.

     11 (c) Sherwood  may  terminate  this  Agreement at any time on thirty (30)
days notice in writing to Licensor.

SECTION 12. ASSIGNABILITY

     12(a) This  Agreement  may be assigned  by Licensor  and shall inure to the
benefit of its successors,  assigns or other legal representatives.  Without the
prior  written  consent of Licensor,  which may be withheld for any or no reason
whatsoever,  Sherwood  may not assign any rights  arising  under this  Agreement
except to a Related  Company  or to the  successor  in  interest  to the  entire
syringe business of Sherwood which, in any case,  expressly assumes, in writing,
the obligations hereunder.

     12(b) Licensor agrees to notify Sherwood in writing within thirty (30) days
of any change in ownership  or transfer of rights in any of the Licensed  Patent
Rights from any owner to any third party.

SECTION 13. NOTICES AND PAYMENTS

     13(a) Any notice, request,  consent, demand or other communication given or

SECTION 15. TECHNICAL AND OTHER INFORMATION; CONFIDENTIALITY

     15(a) To the best of Licensor's knowledge,  any Licensed Know-how disclosed
under this Agreement is correct.  However,  nothing herein shall be construed to
indicate that Licensor in any manner  guarantees the correctness of the Licensed
Know-how,  or that Licensor assumes any liability whatsoever for any products or
parts thereof manufactured and sold by Sherwood in accordance with said Licensed
Know-how,  or as a result of the use  thereof.  Sherwood  shall  assume all such
liabilities  and hold Licensor  harmless from any liability  resulting  from the

as herein provided.

     15(b) Subject to the  provisions of this  Agreement,  until the end of five
years after the expiration of the  last-to-expire  of the Licensed Patent Rights
in the Licensed  Territory,  Sherwood  shall respect and ensure  respect for the

processes and secrets pertaining to the Licensed Know-how and shall not disclose
nor allow the same to be disclosed to any other person without the prior written

          (2)  can  be  established  by  documentary   evidence  that  prior  to
     disclosure by Licensor, was in Sherwood's possession without restriction on
     disclosure  imposed  by  any  third  party  (and  not in  violation  of any

                              EMPLOYMENT AGREEMENT

         AGREEMENT dated as of January 1, 1997 between UNIVEC, Inc., a Delaware
corporation (the "Company"), having its principal office at 999 Franklin Avenue,
Garden City, New York 11530, and Joel Schoenfeld, an individual (the "Employee")
residing at 3 Eagle Chase, Woodbury, New York 11797.

         WHEREAS, the Employee has been employed by the Company as Chairman of
the Board and Chief Executive since August 1992;

         WHEREAS, the Company desires to continue the employment of the Employee
and Employee agrees to continue his employment with the Company on the terms and
conditions herein provided;

         NOW THEREFORE, in consideration of the premises and the mutual
agreements herein set forth, the parties hereby agree as follows:

         1. Employment and Duties. During the term of this Agreement, the
Employee shall serve as the Company's Chairman of the Board and Chief Executive
Officer, and in such capacity shall be the principal executive officer of the
Company.

         2. Term. Subject to the termination provisions of Section 5 hereof,
Employee's employment by the Company hereunder is for a term commencing on the
date hereof and ending on March 28, 2000 (the "Employment Term").

         3. Compensation. During the Employment Term, the Company shall pay the
Employee for his services hereunder at a base salary of $192,000 per annum. The


<PAGE>

base salary shall be paid to the Employee in appropriate installments in 
accordance with the Company's usual and customary payroll practices for its
executive officers.

         4. Benefits. The Company shall pay the Employee an automobile allowance
of $9,000 per annum and provide the Employee with life, disability and health
insurance benefits with coverages no less favorable than those in effect on the
date herof. Employee also shall be entitled to participate in any and all
benefit plans of the Company made available to executive officers of the
Company.

         5. Reimbursement. During the Employment Term, the Company shall
reimburse the Employee for all reasonable and necessary business expenses
incurred and paid directly by him in the performance of his duties hereunder,
upon submission to the Company of reasonably detailed expense reports and
appropriate vouchers and/or receipts prepared in accordance with the applicable
provisions and regulations of the Internal Revenue Code of 1986, as amended.

         6. Termination. Notwithstanding any provision of this Agreement to the
contrary, the Employee's employment hereunder shall terminate immediately upon
the death of the Employee. Except as otherwise specifically provided herein or
as accrued for services performed through the date of termination, all of
Employee's rights to compensation hereunder shall cease to exist effective upon
the date of termination.

         7. Developments. The Employee agrees promptly to disclose in writing to
the Company any invention or discovery made by him during his employment with
the Company, whether during or after working hours, that relates to (i) any
disposable medical devices for drug delivery, including but not limited to
hypodermic needles, (ii) inventions developed for the Company through projects
participated in by Employee and (iii) processes, including equipment used to

                                       -2-

<PAGE>

produce items covered by clauses (i) and (ii) (the items referred to in clauses
(i), (ii) and (iii) being hereinafter referred to collectively as "Covered
Inventions"), and such inventions and discoveries shall be the Company's sole
property. Upon the Company's request, whether during or after the term of his
employment, Employee shall execute and assign to the Company all applications
for letters patent and copyrights of the United States and such foreign
countries as the Company may designate relating to Covered Inventions, and
Employee shall execute and deliver to the Company such other instruments as the
Company deems necessary to vest in the Company the sole ownership of all
exclusive rights in and to such inventions and discoveries, as well as the
patents and/or copyrights. If services in connection with applications for
patents and/or copyrights are performed by Employee at the Company's request
after the termination of his employment, the Company shall pay him reasonable
compensation for such services rendered after termination of this Agreement.

         8. Non-Competition. During the Employment Term and for a period of
twelve (12) months after the termination of this Agreement, however occasioned,
Employee shall not within the United States, Canada, Mexico or Japan, directly
or indirectly, as principal, agent, stockholder, joint venturer, investor,
employee, consultant, officer, director, partner, adviser, guarantor or in any
other capacity, render services or provide advice relating to, or otherwise
engage in or assist others in engaging in, any Competitive Business, or own or
control any interest in any entity which is so engaged. As used herein,
"Competitive Business" means the design, manufacture, marketing, sale or
distribution of any Covered Inventions. Anything to the contrary in the
foregoing notwithstanding, Employee may own, beneficially or legally, up to one
percent (1%) of the outstanding securities of any organization registered under
Section 12 of the Securities Exchange Act of 1934, as amended, or which are
otherwise publicly traded.

                                       -3-

         9. Non-Solicitation. The Employee agrees that he will not during the
term of this Agreement and for a period of one (1) year following the
termination of his employment with the Company for any reason, directly or
indirectly, solicit or contact any employee of the Company with a view to
encouraging such employee to leave the employ of the Company for the purpose of
being hired by him, or any employer affiliated with him, or any competitor of
the Company.

         10. Confidentiality. Executive agrees that he will not, during the term
of this Agreement and thereafter, use or disclose to any individual, firm,
corporation, partnership, business trust, or other business entity (any of the
foregoing being hereinafter referred to as a "Person") any confidential or
proprietary information of the Company for any reason or purpose whatsoever, nor
shall he make use of any such confidential or proprietary information for his
own purpose or for the benefit of any Person other than the Company, including
but not limited to any and all patents (issued or pending), designs, drawings,
blueprints, manufacturing processes, specifications, test data, graphics, charts
and all other technical information, currently in existence or subsequently
developed, relating to the Company's research and development activities and
marketing strategy, or information relating to the Company's costs, pricing
practices, customer lists or financial data; except that nothing herein shall be
construed to prohibit him from complying with legal process or using or
disclosing such information if it shall have become public knowledge other than
by or as a result of disclosure by a Person not having a right to make such
disclosure.

         11. Specific Performance. Employee acknowledges that the covenants set
forth in Paragraphs 7, 8, 9 and 10 are reasonable and necessary for the
protection of the Company and that his violation of any of the such provisions
shall cause the Company immediate and irreparable harm and he agrees that in
such event, an injunction restraining him from such violation or threatened

                                       -4-

<PAGE>

violations may be entered against him in addition to any other remedy available
to the Company. Employee waives any right which he may otherwise have to assert
in any such proceeding that the Company has an adequate remedy at law.

         12. Assignment. This Agreement shall be binding and inure to the
benefit of the Company, its successors and permitted assigns and to the
Employee, his heirs and personal representatives. However, neither this
Agreement nor any of the rights of the parties hereunder may be transferred or
assigned by either party hereto, except that if the Company merges or
consolidates with or into or sells or otherwise transfers substantially all its
assets to another corporation which assumes the Company's obligations under this
Agreement, the Company may assign its rights hereunder to that corporation. Any
other attempted transfer or assignment in violation of this paragraph shall be
void. Since this is a contract for personal services, only the Employee is
deemed capable of performing the services contemplated hereunder.

         13. Waiver. The failure of a party to insist upon strict adherence to
any term of this Agreement on any occasion shall not be considered a waiver
thereof or deprive that party of the right thereafter to insist upon strict
adherence to that term or any other term of this Agreement. Any waiver of any
breach of any provision of this Agreement shall not constitute a waiver of any
other breach of such provision or any other provision hereof.

         14. Notices. Any demand, notice or other communication under this
Agreement shall be in writing and shall be deemed duly given, and received by
the addressee at the address stated above (or at such other address as may be
specified by a party in a written notice delivered in accordance with the
provisions of this Paragraph) upon receipt, duly evidenced if (i) mailed by
certified or registered mail, return receipt requested, with postage prepaid

                                       -5-

<PAGE>

(ii) deposited with a recognized overnight courier service such as Federal
Express, UPS or Express Mail, (iii) by hand delivery, or (iv) upon the receipt
of actual written notice.

         15. Indemnification. Employee shall be entitled throughout the term of
this Agreement and thereafter to indemnification in respect of any actions or
omissions as an officer of the Company (or any successor pursuant to Paragraph
11 hereof) to the fullest extent permitted by the Delaware General Corporation
Law or other applicable law.

         16. Entire Agreement. This Agreement constitutes the entire agreement
between the parties as of the date hereof with respect to Employee's employment
by the Company, superseding all prior or contemporaneous understandings or
agreements, oral or written. This Agreement may not be modified or amended,
except by subsequent written agreement of the parties which specifically states
that it is intended to be a modification, amendment or supplement to this
Agreement, and is signed by all of the parties hereto. No course of dealing or
custom shall be referred to as modifying any of the terms and conditions of this
Agreement.

         17. Governing Law. This Agreement shall be governed by, and construed
in accordance with, the laws of the State of New York applicable to contracts
made and to be performed wholly within that State, and any action, suit or
proceeding which shall be permitted by this Agreement, or by action of law,
shall be commenced in any court having jurisdiction in New York County, or in
the United States District Court for the Southern District of New York, and the
parties hereto hereby waive any objection to jurisdiction or venue in any such
action, suit or proceeding commenced in such courts.

         18. Arbitration. Except as specifically provided in Paragraph 11 of
this Agreement, any and all claims, disputes and other matters in question with

                                       -6-

<PAGE>

respect to, arising out of, under or in connection with this Agreement,
including without limitation, the validity, interpretation, performance and
breach hereof, or the rights and privileges provided by, or responsibilities and
obligations under this Agreement, shall be finally decided by arbitration in the
City of New York before three (3) arbitrators in accordance with the Rules of
the American Arbitration Association then in effect, unless the parties mutually
agree otherwise. This Agreement to arbitrate shall be specifically enforceable
under the prevailing arbitration law. The award rendered by the arbitrators
shall be final, and judgment may be entered upon it in accordance with
applicable law in any court having jurisdiction thereof. The parties agree that
the arbitrators will have full authority to award the costs of the arbitration,
including attorneys' fees.

         19. Severability. In the event any provision of this Agreement is held
invalid or unenforceable by any court of competent jurisdiction, such holding
shall not invalidate or render unenforceable any other provision hereof. Such
invalid or unenforceable provision shall be amended, if possible, in order to
accomplish the purposes of this Agreement.

         20. Headings. The headings of the various sections of this Agreement
have been inserted for convenience of reference only and shall not be deemed to
be a part of this Agreement.

         IN WITNESS WHEREOF, the parties have executed this Agreement on the
date first above written.
