                        1,612,786 SHARES OF COMMON STOCK

  This Prospectus relates to 1,612,786 shares (the "Shares") of common stock,
par value $.001 per share ("Common Stock") of Life Medical Sciences, Inc. (the
"Company") which may be offered for sale from time to time (the "Offering") by
certain selling stockholders (the "Selling Stockholders"). See "Selling
Stockholders and Plan of Distribution."

  The Shares may be offered by the Selling Stockholders from time to time in
transactions (which may include block transactions) in the over-the-counter
market, in negotiated transactions, through the writing of options on the Shares
or a combination of such methods of sale, at fixed prices that may be changed,
at market prices prevailing at the time of sale, or at negotiated prices. The
Selling Stockholders may effect such transactions by selling the Shares directly
to purchasers or through broker-dealers that may act as agents or principals.
Such broker-dealers may receive compensation in the form of discounts,
concessions or commissions from the Selling Stockholders and/or the purchasers
of Shares for whom such broker-dealers may act as agents or to whom they sell as
principals, or both (which compensation as to a particular broker-dealer might
be in excess of customary commissions).

  The Selling Stockholders and any broker-dealers that act in connection with
the sale of the Shares as principals may be deemed to be "underwriters" within
the meaning of Section 2(11) of the Securities Act of 1933, as amended (the
"Securities Act") and any commission received by them and any profit on the
resale of the Shares and/or as principals might be deemed to be underwriting
discounts and commissions under the Securities Act. The Selling Stockholders may
agree to indemnify any agent, dealer or broker-dealer that participates in
transactions involving sales of the Shares against certain liabilities,
including liabilities arising under the Securities Act. Sales of the Shares by
the Selling Stockholders, or even the potential of such sales, could have an
adverse effect on the market price of the Common Stock. There can be no
assurance that Selling Stockholders will be able to sell some or all of the
Shares listed for sale herein.

  The Shares offered by this Prospectus may be sold from time to time by the
Selling Stockholders or by transferees, commencing on the date of this
Prospectus. The Company will not receive any of the proceeds from the sales of
the Shares by the Selling Stockholders. The Company has agreed to indemnify the
Selling Stockholders against certain liabilities, including liabilities under
the Securities Act.

  The Common Stock is listed on The Nasdaq National Market ("Nasdaq"), under the
symbol "CHAI".

       AN INVESTMENT IN THESE SECURITIES INVOLVES A HIGH DEGREE OF RISK.

           SECURITIES AND EXCHANGE COMMISSION OR ANY STATE SECURITIES
               COMMISSION PASSED UPON THE ACCURACY OR ADEQUACY OF

                                  THE COMPANY

 The Company is a biotechnology company engaged in the development and
commercialization of innovative and cost-effective medical products for
therapeutic applications. The Company's proposed products are derived from its
two proprietary platform technologies: (i) its in-situ (occurring on or at a
body site) tissue culturing technology, and (ii) its polymer technology. The
Company's strategy is to apply its platform technologies to the development of
multiple products that address unmet therapeutic needs or offer improved, cost-
effective alternatives to current methods of treatment. Products currently under
development focus on wound healing, stimulating hair regrowth, improving the
success rate of autologous fat transplantation and preventing or reducing post-
operative surgical adhesions. The Company's proposed products are in various
stages of clinical trials and preclinical studies.

 The Company's in-situ tissue culturing technology utilizes proprietary,
defined, serum-free combinations of nutrients and hormones which, when applied
to the body, promote cell growth by: (i) directly supplying essential components
required for cell growth, (ii) stimulating new blood vessel formation
(angiogenesis) and (iii) increasing the flow of blood through existing vessels
(vasodilation). The Company believes that this technology has therapeutic
potential across a broad range of applications in the area of tissue repair and
preservation including acute and chronic wound healing, stimulating hair
regrowth, reducing hair loss, improving the success rate of autologous fat
transplantation for cosmetic and reconstructive surgeries, treating urinary
stress incontinence, and enhancing the outcome of tissue grafting and certain
surgical procedures.

 The Company's polymer technology is based on a proprietary group of polymers.
The Company believes that these polymers display desirable properties which
enable them to be tailored to a wide variety of applications. These properties
include bioresorbability, flexibility, strength and enhanced biocompatibility.
Potential applications for products derived from these polymers are in the
medical area, such as the prevention of post-operative surgical adhesions, as
well as in consumer health and hygiene and industrial areas.

 The Company's current development efforts are focused on the following proposed
products:

 .  Cariel--an in-situ tissue culturing based product for the treatment of
   chronic wounds such as venous stasis, diabetic and decubitus (pressure sore)
   ulcers and other wounds such as burns. Cariel is applied directly to the
   wound site in a gel form. Clinical testing of Cariel for wound healing has
   been ongoing since 1992. In one uncontrolled clinical study, wound closure
   was accomplished without the use of compression, the current conventional
   therapy which requires professional medical care and is burdensome to the
   patient. Based on published industry sources, the

                                       3
<PAGE>
 
   Company believes that products on the market for the treatment of chronic
   wounds generate approximately $3 billion in annual sales in the United States
   alone.

 .  Piliel--an in-situ tissue culturing based product to stimulate hair regrowth
   and reduce hair loss. The user applies Piliel directly to the scalp in a
   viscous liquid form. A pilot clinical study of Piliel was completed in Israel
   in 1995. In this uncontrolled study, investigators observed that Piliel
   stimulated hair regrowth. According to industry sources, approximately 33
   million males and 19 million females in the United States experience some
   form of hair loss.

 .  Lipoel--an in-situ tissue culturing based product to improve the success of
   autologous fat transplantations. Autologous fat transplantations involve the
   transplantation of fat tissue from a donor site to a recipient site in the
   same individual. Autologous fat transplantations may be used in cosmetic and
   reconstructive surgeries as well as for the treatment of urinary stress
   incontinence. In 1995, the Company initiated a pilot clinical study of Lipoel
   in Israel for reconstructive surgery. Based on observations by clinical
   investigators to date, the Company believes that Lipoel-enhanced fat
   transplants may provide better cosmetic results, safety advantages and 
   longer-term benefits than non-Lipoel-enhanced fat transplants and other
   current alternative treatments. The Company believes that there are several
   significant potential markets for Lipoel.

 .  Repel--a proprietary resorbable adhesion barrier film based on the Company's
   polymer technology. Repel is intended to be used routinely during surgeries
   to prevent or reduce the formation of post-operative surgical adhesions. The
   Company conducted several preclinical studies of Repel in the United States
   in 1995 and 1996. These studies have shown that Repel eliminates or
   significantly reduces adhesions following surgery in an animal model.

 .  Scar Care--an externally worn silicone-based product to be applied to intact
   skin for diminishing unsightly scars and associated discomfort. Clinical
   trials for this product have been ongoing since 1995. Based on observations
   by clinical investigators to date, the Company believes that Scar Care may
   diminish the size and discoloration of scars as well as alleviate associated
   itching and discomfort.

 The Company's product development strategy is to maintain a relatively small
core of scientists and researchers within the Company. The Company currently
conducts substantially all of its research and product development through
arrangements with specialized academic and industrial organizations which
broaden the development capabilities of the Company. The Company's
commercialization strategy is to seek joint venture, licensing or collaborative
arrangements for the manufacturing, marketing and sale of its products.

 The Company previously developed and marketed the Sure-Closure System(TM), a
disposable wound closure device. As a result of a strategic decision to focus on
the development and commercialization of its proposed products utilizing its
platform technologies, the Company, in July 1994, sold the Sure-Closure System
to MedChem Products, Inc. In 1996, the Sure-Closure System was acquired by
Zimmer, Inc., a subsidiary of Bristol-Meyers Squibb. The Company receives a 10%
royalty on all net sales of the Sure-Closure System products through June 30,
2004.

 The Company has filed intent to use applications with the United States Patent
and Trademark Office for the following trademarks: Cariel, Piliel, Lipoel and
Repel.

                                  RISK FACTORS

   An investment in the securities offered hereby involves a high degree of
risk. In addition to the other information in this Prospectus and the
information incorporated herein by reference, the following risk factors should
be considered carefully by potential purchasers in evaluating an investment in
the securities offered hereby.

RISK THAT TECHNOLOGIES OR PROPOSED PRODUCTS WILL NEVER BE SUCCESSFULLY DEVELOPED

   The Company's technologies and proposed products are still under development
and are subject to the risks of failure inherent in the development of new
technologies and products based on new technologies. The Company currently has
no products approved for commercial use and has not yet generated revenues from
the commercialization of products based on its technologies (other than its
former product, the Sure-Closure System). The Company's new technologies and
proposed products will require significant further research, development and
testing, including extensive clinical testing and regulatory approval, prior to
commercial use. Unsuccessful results from clinical trials of the Company's
proposed products or adverse findings with respect to these products could
adversely affect some or all of the Company's proposed products. No assurance
can be given that such proposed products will prove to be safe, efficacious and
non-toxic, receive requisite regulatory approvals, demonstrate substantial
therapeutic benefit, be commercialized on a timely basis, experience no design
or manufacturing problems, be manufactured on a large scale, be economical to
market, be accepted by the marketplace, or generate sufficient revenues to
support future research and development programs. In addition, no assurance can
be given that proprietary rights of third parties will not preclude the Company
from marketing its proposed products or that third parties will not market
superior or equivalent products.

RISKS ASSOCIATED WITH UNCERTAINTIES OF CLINICAL TRIALS

   The Company is required to obtain approval from the United States Food and
Drug Administration ("FDA") prior to marketing its proposed therapeutic products
in the United States and the approval of foreign regulatory authorities to
commercialize its proposed products in other countries. To obtain such
approvals, the Company is required to prove the safety and efficacy of its
proposed products through extensive preclinical studies and clinical trials. The
Company is in various stages of such testing. The completion of any of the
Company's clinical trials is dependent upon many factors including the rate of
patient enrollment and the heterogeneity of the patients and indications to be
treated. Delays in patient enrollment, as well as the heterogeneity of patients
and indications to be treated, may result in increased trial costs and delays in
FDA submissions, which could have a material adverse effect on the Company.

   A number of companies in the biotechnology and pharmaceutical industries have
suffered significant setbacks in clinical trials, even after showing promising
results in earlier studies or trials. Although the Company has obtained
favorable results to date in preclinical studies and clinical trials of certain
of its proposed products, such results may not be predictive of results that
will ultimately be obtained in or throughout such preclinical studies and
clinical trials. There can be no assurance that the Company will not encounter
problems in its clinical trials that will cause the Company to delay or suspend
its clinical trials, that the clinical trials of its proposed products will be
completed at all, that such testing will ultimately demonstrate the safety or
efficacy of such proposed products or that any proposed products will receive
regulatory approval on a timely basis, if at all. If any such problems occur,
the Company could be materially and adversely affected.

CAPITAL NEEDS; UNCERTAINTY OF ADDITIONAL FUNDING; LOSS ON SALE OR MERGER

   Although the Company believes that available cash will be sufficient to meet
its cash requirements for approximately the next 24 months, there can be no
assurance that the Company will not require additional financing during that
time or that financing will be available on acceptable terms or at all.
Following such 24 month period, the Company will be required to raise
substantial additional funds to continue to conduct necessary research and
development, preclinical studies and clinical trials, to commercialize its
proposed products, and to fund the growth that is expected to occur if any of
its proposed products are approved for marketing. The Company plans to seek such
additional funding through collaborative arrangements with strategic partners,
licensing arrangements for certain of its proposed products, and additional
public or private financings, including equity financings. Any additional equity
financings may be dilutive to stockholders, including purchasers of the
securities offered hereby. There can be no assurance that such arrangements or
financings will be available as needed or on terms acceptable to the Company.
Insufficient funds may require the Company to delay, scale back or eliminate
some

                                       6
<PAGE>
 
or all of its research and development programs and manufacturing and marketing
efforts, or require it to license to third parties certain products or
technologies that the Company would otherwise seek to commercialize itself. If
the Company is not able to raise additional funds as needed to continue its
research and development programs and for its intended manufacturing and
marketing efforts, it may become necessary for the Company to attempt to be
merged or sold in whole or in part with or to another entity. There can be no
assurance that such a sale or merger would be available, but if it were, the
proceeds to the Company or its stockholders from such a sale or merger could be
substantially less than the amount invested by stockholders in the Company,
resulting in significant losses to the stockholders on their investment in the
Company's securities.

LIMITED OPERATING HISTORY; HISTORY OF LOSSES

   The Company has a limited history of operations that, to date, has consisted
primarily of research, development and testing of its technologies and the
commercialization of the Sure-Closure System. With the exception of the third
quarter of 1994, when the gain on the sale of the Sure-Closure System was
realized, the Company has incurred significant net losses from its inception.
The Company experienced net losses of $6,916,536, $3,398,867, and $2,797,296 for
the years ended December 31, 1993, 1994 and 1995, respectively. At September 30,
1996, the Company had an accumulated deficit of $18,852,632 which has increased
since that date. The Company continues to expend substantial financial and other
resources on (i) research, development and testing of its in-situ tissue
culturing technology and proposed products utilizing this technology; (ii)
research, development and testing of its polymer technology and proposed
products utilizing this technology; (iii) research, development and testing of
other proposed products; and (iv) general and administrative expenses. The
Company expects to incur additional losses as its research, development and
preclinical studies and clinical trials continue to expand. The Company's
ability to achieve a profitable level of operations is dependent on successfully
completing the development of its proposed products, obtaining required
regulatory approvals, and manufacturing and selling its proposed products.
Accordingly, the extent of future losses and the time required to achieve
profitability, if ever, is uncertain. There can be no assurance that the Company
will achieve or sustain a profitable level of operations.

NO ASSURANCE OF REGULATORY APPROVALS; POTENTIAL DELAYS

   The Company's proposed products will be subject to regulation by the FDA and
comparable agencies in foreign countries. The regulatory approval process often
takes a number of years and requires the expenditure of substantial funds. In
the United States, the FDA enforces, where applicable, development, testing,
labeling, manufacturing, registration, notification, clearance or approval,
marketing, distribution, recordkeeping and reporting requirements for new drugs,
medical devices, biologics and cosmetics. In addition, there can be no assurance
that government regulations applicable to the Company's products or the
interpretation of those regulations will not change and thereby prevent the
Company from marketing some or all of its products temporarily or permanently.
There can be no assurance that any proposed products that may be developed by
the Company will be able to satisfy the current requirements and regulations of
the FDA or comparable foreign agencies. There can be no assurance that the
Company's proposed products will ever obtain the regulatory clearance or
approval required for marketing. Products currently being developed utilizing
the in-situ tissue culturing technology will likely be regulated as new drugs or
biologic products, each of which faces a substantially more burdensome
regulatory approval process than that applicable to most medical devices.
Products utilizing the Company's polymer technology are likely to be regulated
by the FDA as medical devices.

   Whether or not FDA approval has been obtained, approval of a drug by
comparable regulatory authorities in other countries must be obtained prior to
marketing the product in those countries. The approval process varies by country
and the time required may be longer or shorter than that required for FDA
approval. Approval of a drug for sale in one country does not ensure approval in
other countries. The results of Phase I or Phase II studies are not necessarily
indicative of the efficacy or safety of a drug candidate for human therapeutic
use. There can be no assurance that clinical testing will provide evidence of
safety and efficacy in humans or that regulatory approvals will be granted for
any of the Company's products. Manufacturers of therapeutic products are
required to obtain FDA approval of their manufacturing facilities and processes,
to adhere to applicable standards for manufacturing practices and to engage in
extensive recordkeeping and reporting. Failures to obtain or delays in obtaining
regulatory approvals would adversely affect the manufacturing and marketing of
the Company's products, the Company's financial position and the Company's
revenues or royalties. When and if approvals are granted, the Company, the
approved drug, the manufacture of such drug and the facilities in which such
drug is manufactured are subject to ongoing regulatory review. Subsequent
discovery of previously unknown problems may result in restriction

                                       7
<PAGE>
 
on a product's use or withdrawal of the product from the market. Adverse
government regulation that might arise from future legislative or administrative
action, particularly as it relates to healthcare reform and product pricing,
cannot be predicted.

PATENTS AND PROPRIETARY RIGHTS; NO ASSURANCE OF ENFORCEABILITY OR SIGNIFICANT
COMPETITIVE ADVANTAGE

   The Company's success will depend heavily on its ability to obtain and retain
patent protection for its in-situ tissue culturing technology, its polymer
technology, and any proposed products, to preserve its trade secrets and to
operate without infringing the proprietary rights of third parties. The Company
owns one United States patent and four pending United States patent applications
relating to its in-situ tissue culturing technology and owns two United States
patents, one Canadian patent and two Israeli patents relating to its polymer
technology. In addition, the Company has filed for patents in a number of
countries and intends to file additional patent applications in other countries.
There can be no assurance that the claims in the pending patent applications
will issue as patents, that any issued patents will provide the Company with
significant competitive advantages, that challenges will not be instituted
against the validity or enforceability of any patent owned by the Company, or,
if instituted, that such challenges will not be successful. The cost of
litigation to uphold the validity and prevent infringement of a patent can be
substantial. Furthermore, there can be no assurance that others will not
independently develop similar or superior technologies, duplicate the Company's
technologies or design around the patented aspects of the Company's
technologies. The Company could incur substantial costs in proceedings before
the United States Patent Office, including interference proceedings. The
proceedings could also result in adverse decisions as to the patentability of
the Company's licensed or assigned inventions. Further, there can be no
assurance that the Company will not infringe upon prior or future patents owned
by others, that the Company will not need to acquire licenses under patents
belonging to others for technology potentially useful or necessary to the
Company, or that such licenses will be available to the Company, if at all, on
terms acceptable to the Company. Moreover, there can be no assurance that any
patent issued to or licensed by the Company will not be infringed by others.
Lastly, there can be no assurance that third parties will not bring suits
against the Company for patent infringement or for declaratory judgment to have
the patents owned or licensed by the Company declared invalid. While obtaining
patents is deemed important by the Company, patents are not considered essential
to the success of its business. However, if further patents do not issue from
present or future patent applications, the Company may be subject to greater
competition. The Company also relies on trade secrets and other unpatented
proprietary technology to protect its innovations. There can be no assurance
that the Company can meaningfully protect its rights in such unpatented
technology, that others will not independently develop substantially equivalent
or superior products and processes or otherwise gain access to the Company's
technologies, that trade secrets will be established or that secrecy obligations
will be honored. To the extent that consultants, key employees, third parties
involved in the Company's projects or others independently develop technological
information, disputes may arise as to the proprietary rights to such
information, which may not be resolved in favor of the Company.

   The Company seeks to protect its trade secrets and proprietary know-how, in
part, through confidentiality agreements with its employees, consultants,
advisors, collaborators and others. There can be no assurance that these
agreements will not be violated by the other parties, that the Company will have
adequate remedies for any breach, or that the Company's trade secrets will not
otherwise become known or be independently developed by competitors. The Company
has relationships with a number of consultants who are employed by organizations
other than the Company. These persons may have consulting, employment or
advisory arrangements with other entities that may conflict or compete with
their obligations to the Company. Consultants generally sign agreements that
provide for confidentiality of the Company's proprietary information and results
of studies. There can be no assurance, however, that the Company will, in
connection with every relationship, be able to maintain the confidentiality of
the Company's technology, dissemination of which could have a materially adverse
effect on the Company's business. To the extent that the Company's scientific
consultants develop inventions or processes independently that may be applicable
to the Company's proposed products, disputes may arise as to the ownership of
the proprietary rights to such information. Such inventions or processes will
not necessarily become the property of the Company, but may remain the property
of such persons or their full-time employers. The Company could be required to
make payments to the owners of such inventions or processes, either in the form
of cash, equity or a combination thereof. In addition, protracted and costly
litigation may be necessary to enforce and determine the scope and validity of
the Company's proprietary rights.

POTENTIAL DEPENDENCE ON REIMBURSEMENT

   Successful commercialization of the Company's proposed products may depend in
part on the availability of adequate reimbursement from third-party health care
payors such as Medicare, Medicaid, and private insurance plans. Reimbursement
matters include both coverage issues and payment issues. Questions of coverage
raise the issue of whether a product will be paid for at all and under what
circumstances. Questions of payment relate to the amount or level of payment.
Reimbursement policies vary among payors and may depend on the setting in which
a product is used.

   There are numerous governmental third-party payors. Medicare is a federally
funded health insurance for persons age 65 or older, who have end stage renal
disease, or otherwise qualify by virtue of a disability. Medicare is the largest
single health insurance program in the United States. Medicaid is a joint
federal-state welfare program to provide health services to the indigent. The
Department of Veterans Affairs provides a variety of medical services to
veterans both directly and through arrangements with private health care
providers. The Civilian Health and Medical Program for the Uniformed Services
pays for care and services furnished to dependents of members of the armed
forces. There are also numerous private health insurance plans, including
private nonprofit insurers (e.g., Blue Cross and Blue Shield plans), commercial
insurers, and various types of managed care organizations.

   Significant uncertainty exists as to the reimbursement status of newly
approved health care products. There can be no assurance that adequate third-
party reimbursement will be available for the Company to establish and maintain
price levels sufficient for realization of an appropriate return on its
investment in developing new therapies. Government and other third-party payors
are increasingly attempting to contain health care costs by limiting both
coverage and payment levels for new therapeutic products approved for marketing
by the FDA and by refusing, in some cases, to provide any coverage for uses of
approved products for disease indications for which the FDA has not granted
marketing approval. If adequate coverage and payment levels are not provided by
government and third-party payors for the Company's proposed products, the
market acceptance of these products would be adversely affected. Failure of the
Company's proposed products to be adequately reimbursed by third-party payors
could have a material adverse effect on the Company.

UNCERTAIN MARKET ACCEPTANCE OF PROPOSED PRODUCTS OR THE SURE-CLOSURE SYSTEM

   The Company's future growth and profitability will depend, in large part, on
the acceptance by the medical community of the Company's proposed products. This
acceptance will be substantially dependent on educating the medical community as
to the full capabilities, distinctive characteristics, perceived benefits and
clinical efficacy of the Company's proposed products. There can be no assurance
that the Company's efforts or those of others will be successful or that any of
the Company's proposed products will receive the necessary market acceptance.
Failure of the Company's proposed products to gain market acceptance would have
a material adverse effect on the Company. In addition, part of the Company's
future profitability will depend on the acceptance by the medical community of
the Sure-Closure System since the Company receives royalties from sales of this
product.

RISK OF NOT OBTAINING MANUFACTURING FACILITY AND EXPERIENCED MANUFACTURING
PERSONNEL AND/OR ESTABLISHING MANUFACTURING ARRANGEMENTS WITH OTHERS

   The Company believes it currently has contracted for sufficient manufacturing
capabilities to allow for production of Cariel, Piliel and Repel in quantities
sufficient to support its current clinical programs. The Company intends to seek
out contracts to obtain sufficient manufacturing capabilities to allow for
production of its other proposed products in quantities sufficient to support
its anticipated needs. To be successful, however, the Company must be capable of
manufacturing or contracting for the manufacture of its products in commercial
quantities, in compliance with regulatory requirements and at acceptable costs.
While the Company has pilot scale manufacturing experience, the Company has no
experience in large scale commercial manufacturing. The Company may enter into
contractual arrangements to manufacture its proposed products at such time, if
ever, that such products are successfully developed. There can be no assurance
that the Company will be able to enter into any such arrangements on acceptable
terms, or at all, or that any manufacturer will be able to meet any demand for
such products on a timely basis. The Company may manufacture its proposed
products directly at such time, if ever, that such products are successfully
developed. The Company has no experience with the direct manufacture of these
proposed products although certain of the Company's officers have had experience
in similar activities for other companies. The manufacture of these proposed
products is complex and difficult, and will require the Company to attract and
retain experienced manufacturing personnel and to obtain the use of a
manufacturing facility in compliance with FDA and other

                                       9
<PAGE>
 
regulatory requirements. There can be no assurance that experienced personnel
can be attracted to or retained by the Company, or that the Company will be able
to obtain the financing necessary to manufacture these products directly.

DEPENDENCE UPON SUPPLIERS

   The Company is dependent upon subcontractors to manufacture and deliver
certain components of its proposed products in a timely and satisfactory manner.
Failure to procure such components or any interruption in the supply of such
components could have a materially adverse effect on the Company.

RELIANCE ON ARRANGEMENTS WITH OTHERS; LIMITED MARKETING AND SALES EXPERIENCE

   The Company has limited experience in marketing and sales although certain of
the Company's officers have had experience in similar activities for other
companies. If any of the Company's proposed products are successfully developed,
the Company may rely on joint venture, licensing or collaborative arrangements
for marketing and selling such proposed products in certain geographic markets.
No agreements have been entered into and there can be no assurance that the
Company will be successful in establishing such arrangements, or that its co-
venturer, licensee or collaborator in such arrangements will be successful in
marketing and selling such products. These arrangements may result in the lack
of control by the Company over the marketing and selling of its proposed
products. The Company may choose to market and sell such products directly and,
to do so, the Company would have to develop a specialized marketing and sales
force with technical expertise. There can be no assurance that the Company will
be able to build such a marketing or sales force, that the cost of establishing
such a marketing or sales force will not exceed any product revenues, or that
the Company's direct sales and marketing efforts will be successful. In
addition, the Company will compete with many other companies that currently have
extensive and well-funded marketing and sales operations.

RISK OF TERMINATION OF, OR LOSS OF RIGHTS TO, TECHNOLOGIES UNDER AGREEMENTS WITH
OTHERS

   The Company has acquired the rights to its technologies pursuant to
agreements with research institutions. Such agreements contain provisions
requiring the Company, among other things, to develop, commercialize and/or
market products, to achieve minimum sales and/or income levels within certain
periods of time, to meet minimum funding requirements and to make royalty
payments in order to maintain the patents and other rights granted thereunder.
In addition, the patents and proprietary rights revert to the grantor on certain
dates and/or upon the occurrence of certain conditions. In the event that
certain patents and proprietary rights were to revert to the grantor, the
Company would be materially adversely affected.

DEPENDENCE UPON THIRD PARTIES FOR CLINICAL DEVELOPMENT OF PROPOSED PRODUCTS

   The Company may enter into strategic alliances for the clinical development
of certain of its proposed products. There can be no assurance that the Company
will be successful in obtaining satisfactory agreements with strategic partners.
In addition, there can be no assurance that the interests and motivations of any
strategic partner would be or remain consistent with those of the Company or
that such partner would successfully perform its obligations.

COMPETITION AND TECHNOLOGICAL OBSOLESCENCE

   The Company is engaged in rapidly evolving and highly competitive fields.
Competition from biotechnology companies, medical device manufacturers,
pharmaceutical and chemical companies and other competitors is intense. Many of
these companies have substantially greater capital resources, research and
development staffs, facilities, and experience in obtaining regulatory approvals
than the Company as well as substantially more experience than the Company in
the manufacturing, marketing, and sale of products. Academic institutions,
hospitals, governmental agencies and other public and private research
organizations are also conducting research and seeking patent protection and may
develop competing products or technologies on their own or through joint
ventures. In addition, recently developed technologies or technologies that may
be developed in the future are, or may be, the basis for competitive products.
There can be no assurance that the Company's competitors will not succeed in
developing technologies and products that are more effective and/or less costly
than those being developed by the Company thereby rendering the Company's
technologies not competitive or obsolete. The Company's proposed products may
become obsolete before the Company can obtain approval to market them or before
it can recoup

                                       10
<PAGE>
 
related research and development or commercialization expenses. Competitors may
also be more successful than the Company in production and marketing.

   The Company believes that its competitive position will be based on its
ability to create and maintain scientifically advanced technology and
proprietary products, obtain required government approvals on a timely basis,
develop and manufacture its proposed products on a cost-effective basis and
successfully market its products. There can be no assurance that the Company's
proposed products under development will be able to compete successfully with
existing products or products under development by other companies, universities
and other institutions or that they will attain regulatory approval in the
United States or elsewhere.

UNCERTAINTY RELATED TO HEALTH CARE REFORM MEASURES

   Congress recently has considered several Medicare reform proposals that could
significantly affect the amount of payment for pharmaceutical products,
including the Company's proposed products. For example, Congressional proposals
would implement a prospective payment system for home health services. If
enacted, such proposals could create cost pressures similar to those in
Diagnostic Related Group--based payments for inpatient hospital services.

   Pending legislative proposals would also replace the current Medicaid program
with a "MediGrant" program involving federal block grants to states. If such
legislation were enacted, it could reduce Medicaid payments for the Company's
proposed products. It is uncertain what legislative proposals will be enacted or
what actions federal, state, or private payors may take in response to any
health reform legislation. The Company cannot predict the effect health care
reforms may have on its business, and no assurance can be given that any such
reforms will not have a material adverse effect on the Company.

ANTI-KICKBACK AND FRAUD AND ABUSE LAWS

   Several types of state and federal laws have been applied to restrict certain
marketing practices in the pharmaceutical industry in recent years. These
include anti-kickback statutes and consumer protection laws prohibiting unfair
or deceptive trade practices.

   The federal Medicare/Medicaid anti-kickback statute prohibits persons from
knowingly and willfully offering, paying, soliciting, or receiving remuneration
to induce or in return for purchasing, leasing, ordering, or arranging for or
recommending purchasing, leasing or ordering any service or item payable under
Medicare, Medicaid, or certain other federally funded state health care
programs. These provisions have been broadly interpreted to apply to certain
relationships between manufacturers, prescribers, purchasers of manufacturers'
products, and parties, such as pharmacies, in a position to refer or recommend
purchases.

   There are five statutory exceptions to the basic prohibition against
kickbacks. Such protected practices include properly disclosed discounts or
other reductions in price, payments to bona fide employees, payments to group
purchasing organizations, waivers of coinsurance for Medicare Part B services
for certain individuals who qualify for certain Public Health Service programs,
and payment practices set forth in regulations defining conduct that will not be
subject to enforcement (i.e., the "safe harbors"). The federal safe harbor
regulations contain further refinements of the statutory exceptions, and also
contain safe harbors for, among other things, warranties, personal services
contracts, and reductions in prices to health plans by contract health care
providers. Although failure to satisfy all of the criteria for a particular safe
harbor does not necessarily mean that an arrangement is unlawful, practices that
involve remuneration intended to induce prohibited purchases or recommendations
may be subject to scrutiny if they do not qualify for the safe harbor. The
Company's practices may not in all cases meet all of the criteria for safe
harbor protection from anti-kickback liability.

   Several states also have statutes or regulations similar to the federal
Medicare/Medicaid anti-kickback statute, including some laws which apply
regardless of whether payment for the services in question may be made under
Medicare, Medicaid, or state health programs. A number of states also have
recently sought to regulate pharmaceutical promotion--and particularly
manufacturer-sponsored incentives to promote the utilization of their products--
through state consumer protection statutes.

   Because of the breadth of these statutes, it is possible that some of the
Company's business activities could be subject to challenge under one or more of
such laws.

                                       11
<PAGE>
 
RISK OF USING HAZARDOUS MATERIALS

   Medical and biopharmaceutical research and development involves the
controlled use of hazardous materials. The Company is subject to federal, state
and local laws and regulations governing the use, manufacture, storage, handling
and disposal of such materials and certain waste products. Although the Company
believes that all of its current contractors comply and future contractors will
comply with safety procedures for handling and disposing of such materials under
the standards prescribed by federal, state and local regulations, the risk of
accidental contamination or injury from those materials cannot be completely
eliminated. In the event of such an accident, the Company could be held liable
for any damages that result and any such liability could exceed the resources of
the Company. Although the Company believes that it is in compliance in all
material respects with applicable environmental laws and regulations and
currently does not expect to make material capital expenditures for environment
control facilities in the near-term, there can be no assurance that the Company
will not be required to incur significant costs to comply with environmental
laws and regulations, or any assurance that the operations, business or assets
of the Company will not be materially adversely affected by current or future
environmental laws, rules, regulations or policies.

DEPENDENCE UPON ATTRACTION AND RETENTION OF KEY PERSONNEL AND CONSULTANTS

   The Company is dependent upon a limited number of key management, scientific
and technical personnel. In addition, the Company's future success will depend
in part upon its ability to attract and retain highly qualified personnel. The
Company competes for such personnel with other companies, academic institutions,
government entities and other organizations. There can be no assurance that the
Company will be successful in hiring or retaining qualified personnel. Loss of
key personnel or the inability to hire or retain qualified personnel could have
a material adverse effect on the Company. In addition, the Company relies upon
consultants and advisors to assist the Company in formulating its research and
development strategies, testing and manufacturing-related issues. All of the
Company's consultants and advisors are employed outside the Company and may have
commitments or consulting or advisory contracts with other entities.

RISK OF PRODUCT LIABILITY CLAIMS; INSURANCE

   The Company's business exposes it to potential liability risks that are
inherent in the testing, manufacturing and marketing of medical products. The
use of the Company's proposed products in clinical trials may expose the Company
to product liability claims and possible adverse publicity. These risks also
exist with respect to the Company's proposed products, if any, that receive
regulatory approval for commercial sales. The Company currently has limited
product liability insurance coverage for the use of Cariel, Piliel, Repel and
Scar Care in clinical trials. The Company does not have product liability
insurance for the clinical trials of other proposed products or for the
commercial sale of any of its proposed products, although it intends to obtain
such coverage if and when its products are commercialized. However, there can be
no assurance that the Company will be able to obtain additional insurance
coverage at acceptable costs, if at all, or be able to maintain the current
level of insurance. Further, there can be no assurance that a product liability
claim would not materially adversely affect the Company. A product liability or
other judgment against the Company in excess of the Company's insurance coverage
could have a material adverse effect upon the Company.

RISK INHERENT IN INTERNATIONAL SALES AND OPERATIONS

   The Company intends to sell its proposed products outside of the United
States, as well as domestically. A number of risks are inherent in international
transactions. International sales and operations may be limited or disrupted by
the imposition of governmental controls, regulation of medical devices and other
medical products, export license requirements, political instability, trade
restrictions, changes in tariffs, exchange rate fluctuations and difficulties in
managing international operations.

ANTI-TAKEOVER PROVISIONS

   The Company's Restated Certificate of Incorporation, as amended (the
"Restated Certificate of Incorporation") authorizes the issuance of a maximum of
5,000,000 shares of preferred stock ("Preferred Stock") on terms that may be
fixed by the Company's Board of Directors without further stockholder action.
The terms of any series of Preferred Stock could

                                       12
<PAGE>
 
adversely affect the rights of holders of the Common Stock. No Preferred Stock
has been issued to date and the Company has no current plans to issue Preferred
Stock. The issuance of Preferred Stock could make the possible takeover of the
Company more difficult or otherwise dilute the rights of holders of the Common
Stock and the market price of the Common Stock. In addition, the Company is
subject to Delaware General Corporation Law provisions that may have the effect
of discouraging persons from pursuing a non-negotiated takeover of the Company
and preventing certain changes of control.

SHARES ELIGIBLE FOR FUTURE SALE; OUTSTANDING WARRANTS AND OPTIONS; REGISTRATION
RIGHTS

   Of the Company's 7,914,820 shares of Common Stock currently outstanding,
3,020,658 shares are "restricted securities," as defined in Rule 144 of the
Securities Act. Of the 3,020,658 "restricted securities," 1,212,786 shares are
being registered for resale in the Offering and all 3,020,658 shares of Common
Stock are or will be eligible for sale under Rule 144. The Company is unable to
predict the effect that sales made under Rule 144, or otherwise, may have on the
then prevailing market price of the Common Stock. Any substantial sale of
restricted securities pursuant to Rule 144 may have an adverse effect on the
market price of the Common Stock. 1,133,851 shares of Common Stock issuable upon
exercise of stock options have been registered on a registration statement on
Form S-8.

   The Company has outstanding (i) Class A Warrants and Class B Warrants which
could result in the issuance of 4,768,059 additional shares of Common Stock,
(ii) 775,000 shares of Common Stock issuable upon exercise of options which have
been granted under the Company's Option Plan (the "Plan"), and (iii) 558,851
shares of Common Stock issuable upon exercise of currently outstanding options
granted outside the Plan, of which 200,000 shares of Common Stock issuable upon
exercise of such options are being registered in the Offering. In connection
with the Company's IPO the Company issued Unit Purchase Options ("UPO") to the
underwriter of the IPO which UPO's are convertible into 463,123 shares of Common
Stock, 109,890 Class A Warrants and 219,780 Class B Warrants. In connection with
a recent public offering (the "Third Offering"), the Company sold to Wedbush
Morgan Securities, Inc. a warrant the ("Wedbush Warrant") to purchase 200,000
shares of Common Stock. Such warrant is exercisable for a period of five years,
commencing May 3, 1997 and has an exercise price of $7.95 per share. The Common
Stock underlying the Wedbush Warrant is being registered for resale in the
Offering, and the Company also intends to register the Common Stock underlying
the UPOs for resale. The foregoing options and warrants are likely to be
exercised at a time when the Company might be able to obtain additional equity
capital on more favorable terms. In addition, to the extent they are exercised,
they will decrease the percentage of the Company owned by the Company's
stockholders. While these options and warrants are outstanding, they may
adversely affect the terms on which the Company could obtain additional capital.
The Company cannot predict the effect, if any, that market sales of Common
Stock, the exercise of options or warrants or the availability of such Common
Stock for sale will have on the market price prevailing from time to time. In
addition, if the exercise price of options or warrants are adjusted downward,
such options or warrants may be exercised sooner than otherwise with a resulting
increase in the number of shares of Common Stock available for sale on the
market.

POSSIBLE VOLATILITY OF STOCK PRICE

   The stock market has from time to time experienced significant price and
volume fluctuations that are unrelated to the operating performance of
particular companies. In addition, the market price of the Common Stock has been
and is likely to continue to be highly volatile. Factors such as fluctuations in
the Company's operating results, shortfalls in revenue or earnings from levels
expected by securities analysts, announcements of technological innovations or
new products by the Company or its competitors, governmental regulations,
developments with respect to patents or proprietary rights, litigation, public
concern as to the safety of products developed by the Company or others and
general market conditions may have a significant adverse effect on the market
price of the Common Stock. Between the date of the IPO and the date of this
Prospectus, the Common Stock has traded at per share prices between $1.50 and
$11.38. There can be no assurance that this high level of volatility will not
persist in the future.

RISK OF NO DIVIDENDS
   The Company has never declared or paid any cash dividends on the Common
Stock. There is a risk that the Company may never declare or pay any dividends
on the Common Stock.

                                USE OF PROCEEDS

   The Company will not receive any proceeds from the sale of the Shares by the
Selling Stockholders.

                        DESCRIPTION OF THE COMMON STOCK

   The Company has authorized 23,750,000 shares of Common Stock, par value $.001
per share. Immediately prior to the Offering, there were 7,914,820 shares of
Common Stock outstanding. The holders of the Common Stock are entitled to one
vote per share with respect to all matters on which holders of the Common Stock
are entitled to vote.

   Holders of the Common Stock have the right to dividends from funds legally
available therefor, when, as and if declared by the Board of Directors, are
entitled to share ratably in all of the assets of the Company available for
distribution to holders of shares of Common Stock and do not have preemptive,
subscription, or conversion rights. There are no redemption or sinking fund
provisions for the benefit of the Common Stock in the Restated Certificate of
Incorporation. All outstanding shares of Common Stock are, and those shares of
Common Stock offered hereby issuable upon exercise of options or warrants will
be, validly issued, fully paid and non-assessable.

                 SELLING STOCKHOLDERS AND PLAN OF DISTRIBUTION

   The Shares may be offered by the Selling Stockholder from time to time in
transactions (which may include block transactions) in the over-the-counter
market, in negotiated transactions (including, without limitation, equity
security exchanges), through the writing of options on the Shares or a
combination of such methods of sale, at fixed prices that may be changed, at
market prices prevailing at the time of sale, or at negotiated prices. The
Selling Stockholders may effect such transactions by selling the Shares directly
to purchasers or through broker-dealers that may act as agents or principals.
Such broker-dealers may receive compensation in the form of discounts,
concessions or commissions from the Selling Stockholders and/or the purchasers
of Shares for whom such broker-dealers may act as agents or to whom they sell as
principals, or both (which compensation as to a particular broker-dealer might
be in excess of customary commissions).

   The Selling Stockholders and any broker-dealers that act in connection with
the sale of the Shares as principals may be deemed to be "underwriters" within
the meaning of Section 2(11) of the Securities Act and any commission received
by them and any profit on the resale of the Shares and/or as principals might be
deemed to be underwriting discounts and commissions under the Securities Act.
The Selling Stockholders may agree to indemnify any agent, dealer or broker-
dealer that participates in transactions involving sales of the Shares against
certain liabilities, including liabilities arising under the Securities Act.
Sales of the Shares by the Selling Stockholders, or even the potential of such
sales, could have an adverse effect on the market price of the Common Stock.
There can be no assurance that Selling Stockholders will be able to sell some or
all of the Shares listed for sale herein.

   The following table sets forth certain information with respect to the
Selling Stockholders for whom the Company is registering the Shares for resale
to the public. The Company will not receive any of the proceeds from the sale of
the Shares. There are no material relationships between any of the Selling
Stockholders and the Company except as otherwise indicated. Beneficial ownership
of the Shares by each Selling Stockholder after the sale will depend on the
number of Shares sold by each Selling Stockholder. The Shares offered by the
Selling Stockholders are not being underwritten.

ITEM 15. INDEMNIFICATION OF DIRECTORS AND OFFICERS.

   Reference is made to Section 145 of the Delaware General Corporation Law (the
"DGCL"), Article TENTH of the Registrant's Restated Certificate of
Incorporation, as amended (Exhibit 3.1 and 3.1(a)), Article VIII of the
Registrant's By-Laws (Exhibit 3.2) and the Indemnification Agreements entered
into with certain of the Registrant's directors and officers (Exhibit 10.5).

   Section 145 of the DGCL generally provides that a corporation is empowered to
indemnify any person who is made a party to any threatened, pending or completed
action, suit or proceeding by reason of the fact that he is or was a director,
officer, employee or agent of the corporation or is or was serving, at the
request of the corporation, in any of such capacities of another corporation or
other enterprise, if such director, officer, employee or agent acted in good
faith and in a manner he reasonably believed 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 his conduct was unlawful. This
statute describes in detail the right of the Registrant to indemnify any such
person.

   Article TENTH of the Restated Certificate of Incorporation of the Registrant,
provides generally for mandatory indemnification of the directors and officers
of the Registrant to the fullest extent permitted under the DGCL and permits
indemnification for all other persons whom the Registrant is empowered to
indemnify under the DGCL.

   Pursuant to Article VIII of the Registrant's By-Laws, the Registrant may
indemnify, to the fullest extent permitted by the DGCL, any person, including
officers and directors, with regard to any action or proceeding.

   The Registrant has entered into an indemnification agreement with certain of
its directors and officers. Such agreement provides that the Registrant will
indemnify the indemnitee to the fullest extent permitted by applicable law
against expenses, including reasonable attorneys' fees, judgments, penalties,
fines and amounts paid in settlement actually and reasonably incurred by him in
connection with any civil or criminal action or administrative proceeding
arising out of his performance of his duties as a director or officer of the
Registrant other than an action initiated by a director or officer. Such
indemnification is available if the indemnitee acted in good faith and in a
manner he reasonably believed to be in, or not opposed to, the best interests of
the Registrant, and with respect to any criminal action, had no reasonable cause
to believe his conduct was unlawful.

   Under such indemnification agreement, the entitlement of a director or
officer to indemnification is determined by a majority vote of a quorum of
disinterested directors, or if such quorum either is not obtainable or so
directs, by independent counsel or by the stockholders or the Registrant, as
determined by such quorum of disinterested directors. Under certain
circumstances, a party to the indemnification agreement is conclusively presumed
to have met the applicable statutory standard of conduct unless the Registrant's
Board of Directors, stockholders or independent legal counsel determine that the
relevant standard has not been met. If a change of control of the Registrant has
occurred, the entitlement of such director or officer to indemnification is
determined by independent counsel selected by such director or officer, unless
such director

                                      II-1
<PAGE>
 
or officer requests that either the Board of Directors or the stockholders make
such determination. The Company currently has $2,000,000 of Director and Officer
liability insurance.

   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. See Item 17.
"Undertakings."

ITEM 17. UNDERTAKINGS.

   The undersigned registrant hereby undertakes:

   (a) (1) To file, during any period in which offers or sales are being made, a
post-effective amendment to this registration statement;

                                      II-3
<PAGE>
 
    (i) To include any prospectus required by Section 10(a)(3) of the Securities
Act of 1933;
    (ii) To reflect in the prospectus any facts or events arising after the
effective date of the registration statement (or the most recent post-effective
amendment thereof) which individually or in the aggregate, represent a
fundamental change in the information set forth in the registration statement.
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 and 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 20 percent change in the
maximum aggregate offering price set forth in the "Calculation of Registration
Fee" table in the effective registration statement.

    (iii)  To include any material information with respect to the plan of
distribution not previously disclosed in the registration statement or any
material change to such information in the registration statement;

    (2) That, for the purpose of determining any liability under the Securities
Act of 1933, each such post effective amendment shall be deemed to be a new
registration statement relating to the securities offered therein and the
offering of such securities at that time shall be deemed to be the initial bona
fide offering thereof.

    (3) To remove from registration by means of a post-effective amendment any
of the securities being registered which remains unsold at the termination of
the offering.

   (b) Insofar as indemnification for liabilities arising under the Securities
Act may be permitted to directors, officers and controlling persons of the
Registrant pursuant to the foregoing provisions, or otherwise, the Registrant
has been advised that in the opinion of the 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 Registrant of expenses incurred or
paid by a director, officer or controlling person of the Registrant in the
successful defense of any action, suit or proceeding) is asserted by such
director, officer or controlling person in connection with the securities being
registered, the Registrant will, unless in the opinion of its counsel the matter
has been settled by controlling precedent, submit to a court of appropriate
jurisdiction the question whether such indemnification by it is against public
policy as expressed in the Securities Act and will be governed by the final
adjudication of such issue.

                                                                   EXHIBIT 10.41


                          LIFE MEDICAL SCIENCES, INC.
                             STOCK OPTION AGREEMENT
             UNDER THE AMENDED AND RESTATED 1992 STOCK OPTION PLAN
                             INCENTIVE STOCK OPTION

     AGREEMENT entered into as of this 12th day of June 1995 by and between Life
Medical Sciences, Inc., a Delaware corporation, with a principal place of
business at 214 Carnegie Center in Princeton, New Jersey (the "Company"), and
the undersigned employee of the Company (or one of its subsidiaries) (the
Company and its subsidiaries hereinafter together referred to as the "Company"),
(said employee hereinafter referred to as the "Optionee").

     1.  The Company desires to grant the Optionee an incentive stock option
under the Company's Amended and Restated 1992 Stock Option Plan (the "Plan") to
acquire Shares of the Company's Common Stock, .001 par value (the "Shares").

     2.  The Plan provides that each option is to be evidenced by an option
agreement, setting forth the terms and conditions of the option.

     ACCORDINGLY, in consideration of the premises and of the mutual covenants
and agreements contained herein, the Company and the Optionee hereby agree as
follows:

     1.  Grant of Option.
         --------------- 

     The Company hereby grants to the Optionee an incentive stock option (the
"Option") to purchase all or any part of an aggregate of 60,000 Shares on the
terms and conditions hereinafter set forth. This option shall be treated as an
incentive stock option under Section 422 of the Internal Revenue Code of 1986,
as amended (the "Code").

     2.  Purchase Price.
         -------------- 

     The purchase price ("Purchase Price") for the Shares covered by the Option
shall be $7.00 per share.

     3.  Time of Vesting and Exercise of Option.
         -------------------------------------- 

The Option shall vest and become exercisable in three equal installments, the
first of which shall vest and become exercisable on the date hereof and the
remaining two of which shall vest and become exercisable on the first and second
anniversaries of the date hereof, respectively.
<PAGE>
 
     4.  Term of Options:  Exercisability.
         -------------------------------- 

     (a)  Term.
          ---- 

     (i) The Option shall expire as to each installment five (5) years from the
date such installment shall first become exercisable, but shall be subject to
earlier termination as herein provided.

     (ii) Except as otherwise provided in this Section 4, if the Optionee ceases
to be an employee of the Company, the Option granted to the Optionee hereunder
shall terminate on the earlier of the last day of the month or thirty days after
the date such Optionee ceases to be an employee of the Company, or on the date
on which the Option expires by its terms, whichever occurs first; provided,
however, if (i) the Optionee ceases to be an employee of the Company on account
of his voluntary resignation and (ii) within thirty (30) days after such
resignation the Board of Directors of the Company determines in good faith that
termination for Cause (as defined herein) would have been warranted based on
information that becomes known to the Company, then the Option shall terminate
on the date the Optionee voluntarily resigned from the Company.  The Company
shall have the right to postpone any exercise of this Option for a period of up
to thirty (30) days following voluntary resignation by the Optionee.

     (iii)  If the Optionee's employment is terminated because of dismissal for
Cause (as defined herein) or because the Optionee is in breach of any employment
agreement, such Option will terminate on the date the Optionee ceases to be an
employee of the Company.  "Cause" means any gross malfeasance or conviction of a
felony, in either case directly and materially affecting the Company.  The
determination of "Cause" shall be made in good faith by the Company's Board of
Directors (whose determination shall be final) with a written explanation
thereof provided to the Optionee.

     (iv) If the Optionee's employment is terminated because the Optionee has
become Permanently Disabled (as defined in the Optionee's employment agreement
with the Company of even date herewith), such Option shall terminate on the last
day of the twelfth month from the date such Optionee ceases to be an employee
due to such disability, or on the date on which the Option expires by its terms,
whichever occurs first.

     (v) In the event of the death of the Optionee, the Option granted to such
Optionee shall terminate on the last day of the twelfth month from the date of
death, or on the date on which the Option expires by its terms, whichever occurs
first.

                                      -2-
<PAGE>
 
     (b)  Exercisability.
          -------------- 

     (i) Except as provided below, if the Optionee ceases to be an employee of
the Company, the Option granted to the Optionee hereunder shall be exercisable
only to the extent that the right to purchase Shares under such Option has
accrued and is in effect on the date such Optionee ceases to be an employee of
the Company. No partial exercise may be made for less than one hundred (100)
full Shares of Common Stock.

     (ii) If the Optionee ceases to be an employee of the Company because he or
she has become Permanently Disabled, as defined above, the Option granted to the
Optionee hereunder shall be exercisable to the full number of Shares covered by
such Option.

     (iii)  In the event of the death of the Optionee, the Option granted to the
Optionee may be exercised to the full number of Shares covered thereby whether
or not under the provisions of Section 3 hereof the Optionee was entitled to do
so at the date of his or her death, by the estate of such Optionee, or by any
person or persons who acquired the right to exercise such Option by bequest or
inheritance or by reason of the death of such Optionee.

     5.   Manner of Exercise of Option.
         ----------------------------- 

     (a) To the extent that the right to exercise the Option has accrued and is
in effect, the Option may be exercised in full or in part by giving written
notice to the Company stating the number of Shares exercised and accompanied by
payment in full for such Shares. Upon such exercise, delivery of a certificate
of paid-up, non-assessable Shares shall be made at the principal office of the
Company to the person exercising the Option, not less than thirty (30) and not
more than ninety (90) days from the date of receipt of the notice by the
Company.

     (b) The Company shall at all times during the term of the Option reserve
and keep available such number of Shares of its Common Stock as will be
sufficient to satisfy the requirements of the Option. The Optionee shall not
have any of the rights of a stockholder of the company in respect of the Shares
until one or more certificates for such Shares shall be delivered to him or her
upon the due exercise of the Option.

     6.  Non-Transferability.
         -------------------

                           TO STOCK OPTION AGREEMENT
                           -------------------------

Gentlemen:

          In connection with the exercise by me as to Shares of Common Stock,
 .001 par value, of Life Medical Sciences, Inc. (the "Company") under the
Incentive Stock Option Agreement dated hereunder granted to me under the Amended
and Restated 1992 Stock Option Plan, I hereby acknowledge that I have been
informed as follows:

          1.   The Shares of Common Stock of the Company to be issued to me
pursuant to the exercise of said option have not been registered under the 1933
Act, and accordingly, must be held indefinitely unless such Shares are
subsequently registered under the 1933 Act, or an exemption from such
registration is available.

          2. Routine sales of securities made in reliance upon Rule 144 under
the 1933 Act can be made only after the holding period provided by that Rule,
and,in any sale to which that Rule is not applicable, registration or compliance
with some other exemption under the 1933 Act will be required.

          3. The availability of Rule 144 is dependent upon adequate current
public information with respect to the Company being available and, at the time
that I may desire to make a sale pursuant to the Rule, the Company may neither
wish nor be able to comply with such requirement.

          In consideration of the issuance of certificates for the Shares to me,
I hereby represent and warrant that I am acquiring such Shares for my own
account for investment, and that I will not sell, pledge or transfer such Shares
in the absence of an effective registration statement covering the same, except
as permitted by the provisions of Rule 144, if applicable, or some other
applicable exemption under the 1933 Act. In view of this representation and
warranty, I agree that there may be affixed to the certificates for the Shares
to be issued to me, and to all certificates issued hereafter representing such
Shares (until in the opinion of counsel, which opinion must be reasonable
satisfactory in form and substance to counsel for the Company, it is no longer
necessary or required) a legend as follows:

   "The Shares of Common Stock represented by this certificate have not been
   registered under the Federal Securities Act of 1933, as amended, and were
   acquired by the registered holder pursuant to a representation and warranty
   that such holder was acquiring such Shares for his own account and for
   investment, with no intention of transfer or dispose of the same in violation
   of the registration requirements of that Act. These Shares may not be sold,
   pledged, or transferred in the absence of an effective registration statement
   under such Act, or an opinion of counsel, which opinion is reasonably
   satisfactory to counsel to the Company, to the effect that registration is
   not required under such act."

                                      -6-
<PAGE>
 
          I further agree that the Company may place a stop order with its
Transfer Agent, prohibiting the transfer of such Shares, so long as the legend
remains on the certificates representing the shares.

                              Very truly yours,

Option has accrued and is in effect on

until one or more certificates for such Shares shall be delivered to him or her
upon due exercise of the Option.

     6.  Non-Transferability.

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


Gentlemen:

     In connection with the exercise by me as to Shares of Common Stock, .001
par value, of Life Medical Sciences, Inc. (the "Company") under the Incentive
Stock Option Agreement dated hereunder granted to me under the Amended and
Restated 1992 Stock Option Plan, I hereby acknowledge that I have been informed
as follows:

     1.  The Shares of Common Stock of the Company to be issued to me pursuant
to the exercise of said option have not been registered under the 1933 Act, and
accordingly, must be held indefinitely unless such Shares are subsequently
registered under the 1933 Act, or an exemption from such registration is
available.

     2.  Routine sales of securities made in reliance upon Rule 144 under the
1933 Act can be made only after the holding period provided by that Rule, and in
any sale to which that Rule is not applicable, registration or compliance with
some other exemption under the 1933 Act will be required.

     3.  The availability of Rule 144 is dependent upon adequate current public
information with respect to the Company being available and, at the time that I
may desire to make a sale pursuant to the Rule, the Company may neither wish nor
be able to comply with such requirement.

     In consideration of the issuance of certificates for the Shares to me, I
hereby represent and warrant that I am acquiring such Shares for my own account
for investment, and that I will not sell, pledge or transfer such Shares in the
absence of an effective registration statement covering the same, except as
permitted by the provisions of Rule 144, if applicable, or some other applicable
exemption under the 1933 Act. In view of this representation and warranty, I
agree that there may be affixed to the certificates for the Shares to be issued
to me, and to all certificates issued hereafter representing such Shares (until
in the opinion of counsel, which opinion must be reasonably satisfactory in form
and substance to counsel for the Company, it is no longer necessary or required)
a legend as follows:

     "The Shares of Common Stock represented by this certificate have not been
     registered under the Federal Securities Act of 1933, as amended, and were
     acquired by the registered holder pursuant to a representation and warranty
     that such holder was acquiring such Shares for his own account and for
     investment, with no intention of transferring or disposing of the same in
     violation of the registration requirements of that Act. These Shares may
     not be sold, pledged, or transferred in the absence of an effective
     registration statement under such Act, or

                                      -6-
<PAGE>
 
     an opinion of counsel, which opinion is reasonably satisfactory to counsel
     to the Company, to the effect that registration is not required under such
     act."

     I further agree that the Company may place a stop order with its Transfer
Agent, prohibiting the transfer of such Shares, so long as the legend remains on
the certificates representing the Shares.

                              Very truly yours,

                           TO STOCK OPTION AGREEMENT
                           -------------------------


Gentlemen:

     In connection with the exercise by me of an option to purchase shares of
Common Stock, $.001 par value, of Life Medical Sciences, Inc. (the "Company"), I
hereby acknowledge that I have been informed as follows:

     1.  The shares of Common Stock of the Company to be issued to me pursuant
to the exercise of said option (the "Shares") have not been registered under the
Securities Act of 1933, as amended (the "Securities Act") and, accordingly, must
be held indefinitely unless the Shares are subsequently registered under the
Securities Act, or an exemption from such registration is available

     2.  Routine sales of securities made in reliance upon Rule 144 under the
Securities Act can be made only after the holding period provided by that Rule
has been satisfied, and, in any sale to which that Rule is not applicable,
registration or compliance with some other exemption under the Securities Act
will be required.

     3.  The availability of Rule 144 is dependent upon adequate current public
information with respect to the Company being available and, at the time that I
may desire to make a sale pursuant to the Rule, the Company may neither wish nor
be able to comply with such requirement.

     In consideration of the issuance of certificates for the Shares to me, I
hereby represent and warrant that I am acquiring the Shares for my own account
for investment, and that I will not sell, pledge or transfer the Shares in the
absence of an effective registration statement covering the same, except as
permitted by the provisions of Rule 144, if applicable, or some other applicable
exemption under the Securities Act. In view of this representation and warranty,
I agree that there may be affixed to the certificates for the Shares to be
issued to me, and to all certificates issued hereafter representing the Shares
(until in the opinion of counsel, which opinion must be reasonably satisfactory
in form and substance to counsel for the Company, it is no longer necessary or
required) a legend as follows:

     "The securities represented by this certificate have not been registered
     under the Securities Act of 1933, as amended, and were acquired by the
     registered holder pursuant to a representation and warranty that such
     holder was acquiring the Shares for his own account and for investment,
     with no intention of transfer or disposition of the same in violation of
     the registration requirements of that Act. These securities may not be
     sold, pledged, or transferred in the absence of an effective registration
     statement under such Act, or an opinion of counsel, which

                                      -7-
<PAGE>
 
     opinion is reasonably satisfactory to counsel to the Company, to the effect
     that registration is not required under such Act."

     I further agree that the Company may place a stop transfer order with its
transfer agent, prohibiting the transfer of the Shares, so long as the legend
remains on the certificates representing the Shares.

                              Very truly yours,



Dated: ____________

months' prior written notice to the Company.

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

Gentlemen:

          In connection with the exercise by me of an option to purchase shares
of Common Stock, S.001 par value, of Life Medical Sciences, Inc. (the
"Company"), I hereby acknowledge that I have been informed as follows:

          1.  The shares of Common Stock of the Company to be issued to me
pursuant to the exercise of said option (the "Shares") have not been registered
under the Securities Act of 1933, is amended (the "Securities Act") and,
accordingly, must be held indefinitely unless the Shares re subsequently
registered under the Securities Act, or an exemption from such registration is
avail able.

          2.  Routine sales of securities made in reliance upon Rule 144 under
the Securities Act can be made only after the holding period provided by that
Rule has been satisfied, and, in any sale to which that Rule is not applicable,
registration or compliance with some other exemption under the Securities Act
will be required.

          3.  The availability of Rule 144 is dependent upon adequate current
public information with respect to the Company being available and, at the time
that I may desire to make a ale pursuant to the Rule, the Company may neither
wish nor be able to comply with such equipment.

          In consideration of the issuance of certificates for the Shares to me,
I hereby represent and warrant that I am acquiring the Shares for my own account
for investment, and that I will not sell, pledge or transfer the Shares in the
absence of an effective registration statement covering the same, except as
permitted by the provisions of Rule 144, if applicable, or some other applicable
exemption under the Securities Act. In view of this representation and warranty,
I agree that there may be affixed to the certificates for the Shares to be
issued to me, and to all certificates issued hereafter representing the Shares
(until in the opinion of counsel, which opinion must be reasonably satisfactory
in form and substance to counsel for the Company, it is no longer necessary or
required) a legend as follows:

     "The securities represented by this certificate have not been registered
     under the Securities Act of 1933, as amended, and were acquired by the
     registered holder pursuant to a representation and warranty that such
     holder was acquiring the Shares for his own account and for investment,
     with no intention of transfer or disposition of the same in violation of
     the registration requirements of that Act. These securities may not be
     sold, pledged, or transferred in the absence of an effective registration
     statement under such Act, or an opinion of counsel, which

                                      -7-
<PAGE>
 
     opinion is reasonably satisfactory to counsel to the Company, to the effect
     that registration is not required under such Act."

     I further agree that the Company may place a stop transfer order with its
transfer agent, prohibiting the transfer of the Shares, so long as the legend
remains on the certificates repre senting the Shares.

                              Very truly yours,

                              s/ Robert P. Hickey

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


Gentlemen:

     In connection with the exercise by me of an option to purchase shares of
Common Stock, $.001 par value, of Life Medical Sciences, Inc. (the "Company"), I
hereby acknowledge that I have been informed as follows:

     1.  The shares of Common Stock of the Company to be issued to me pursuant
to the exercise of said option (the "Shares") have not been registered under the
Securities Act of 1933, as amended (the "Securities Act") and, accordingly, must
be held indefinitely unless the Shares are subsequently registered under the
Securities Act, or an exemption from such registration is available.

     2.  Routine sales of securities made in reliance upon Rule 144 under the
Securities Act can be made only after the holding period provided by that Rule
has been satisfied, and, in any sale to which that Rule is not applicable,
registration or compliance with some other exemption under the Securities Act
will be required.

     3.  The availability of Rule 144 is dependent upon adequate current public
information with respect to the Company being available and, at the time that I
may desire to make a sale pursuant to the Rule, the Company may neither wish nor
be able to comply with such requirement.

     In consideration of the issuance of certificates for the Shares to me, I
hereby represent and warrant that I am acquiring the Shares for my own account
for investment, and that I will not sell, pledge or transfer the Shares in the
absence of an effective registration statement covering the same, except as
permitted by the provisions of Rule 144, if applicable, or some other applicable
exemption under the Securities Act. In view of this representation and warranty,
I agree that there may be affixed to the certificates for the Shares to be
issued to me, and to all certificates issued hereafter representing the Shares
(until in the opinion of counsel, which opinion must be reasonably satisfactory
in form and substance to counsel for the Company, it is no longer necessary or
required) a legend as follows:

     "The securities represented by this certificate have not been registered
     under the Securities Act of 1933, as amended, and were acquired by the
     registered holder pursuant to a representation and warranty that such
     holder was acquiring the Shares for his own account and for investment,
     with no intention of transfer or disposition of the same in violation of
     the registration requirements of that Act. These securities may not be
     sold, pledged, or transferred in the absence of an effective registration
     statement under such Act, or an opinion of counsel, which

                                      -7-
<PAGE>
 
     opinion is reasonably satisfactory to counsel to the Company, to the effect
     that registration is not required under such Act."

     I further agree that the Company may place a stop transfer order with its
transfer agent, prohibiting the transfer of the Shares, so long as the legend
remains on the certificates representing the Shares.

                              Very truly yours,

<PAGE>
 
     4.   Term; Extent of Exercisability.
          ------------------------------ 

          (a)    Term.
                 ---- 

          (i) The Option shall expire as to each installment amount on the date
set forth next to each such amount on the signature page to this Agreement (the
"Expiration Date"), subject to earlier termination as herein provided.

          (ii) Except as otherwise provided in this Section 4, if the Optionee
ceases to perform services for the Company, the Option shall terminate on the
earlier of the last day of the third month or ninety days after the date such
Optionee ceases to perform services for the Company, or on the date on which the
Option expires by its terms, whichever occurs first.

          (iii) If such termination to perform services is because of dismissal
for cause or because the Optionee is in breach of any employment agreement, such
Option will terminate on the date the Optionee ceases to perform services for
the Company.

          (iv) If such termination to perform services is because the Optionee
has become permanently disabled (within the meaning of Section 22(e)(3) of the
Code), such Option shall terminate on the last day of the twelfth month from the
date such Optionee ceases to perform services for the Company, or on the date on
which the Option expires by its terms, whichever occurs first.

that the right to purchase Shares under such Option has accrued and is in effect

          (ii) If the Optionee ceases to perform services for the Company
because he or she has become permanently disabled (within the meaning of Section
22(e)(3) of the Code), the Option shall be exercisable to the full number of
Shares covered by such Option.

          (iii) In the event of the death of the Optionee, the Option may be
exercised with respect to the full number of Shares covered thereby whether or
not under the provisions of Section 3 hereof the Optionee was entitled to do so
at the date of his or her death, by the estate of such Optionee, or by any
person or persons who acquired the right to exercise such Option by bequest or
inheritance or by reason of the death of such Optionee.

                                      -2-
<PAGE>
 
     5.   Manner of Exercise of Option.
          ---------------------------- 


          (a) To the extent that the right to exercise the Option has accrued
and is in effect, the Option may be exercised in full or in part by giving
written notice to the Company stat ing the number of Shares as to which the
Option is being exercised and accompanied by payment in full for such Shares. No
partial exercise may be made for less than one hundred (100) full Shares of
Common Stock. Payment shall be made in accordance with the terms of the Plan.
Upon such exercise, delivery of a certificate for paid-up, non-assessable Shares
shall be made at the principal office of the Company to the person exercising
the Option, not less than thirty (30) and not more than ninety (90) days from
the date of receipt of the notice by the Company.

          (b) The Company shall at all times during the term of the Option
reserve and keep available such number of Shares of its Common Stock as will be
sufficient to satisfy the requirements of the Option.

     6.   Non-Transferability.
          ------------------- 

          The right of the Optionee to exercise the Option shall not be
assignable or transferable by the Optionee otherwise than by will or the laws or
descent and distribution or pursuant to a domestic relations order as defined in
the Code or Title 1 of the Employee Retirement Income Security Act or the rules
thereunder, and the Option may be exercised during the lifetime of the Optionee
only by him or her. The Option shall be null and void and without effect upon
the bankruptcy of the Optionee or upon any attempted assignment or transfer,
except as herein provided, including without limitation any purported
assignment, whether voluntary or by operation of law, pledge, hypothecation or
other disposition contrary to the provisions hereof, or levy of execution,
attachment, trustee process or similar process, whether legal or equitable, upon
the Option.

     7.   Representation Letter and Investment Legend.
          ------------------------------------------- 

          In the event that for any reason the Shares to be issued upon exercise
of the Option shall not be effectively registered under the Securities Act of
1933 (" 1933 Act"), upon any date on which the Option is exercised in whole or
in part, the person exercising the Option shall give a written representation to
the Company in the form attached hereto as Exhibit 1 and the Company shall place
an "investment legend", so-called, as described in Exhibit 1, upon any
certificate for the Shares issued by reason of such exercise.

     8.   Adjustments or Changes in Capitalization.
          ---------------------------------------- 

          Adjustments on changes in capitalization and the like shall be made in
accordance with the Plan, as in effect on the date of this Option.

                                      -3-
<PAGE>
 
     9.   No Special Employment Rights.
          ---------------------------- 

          The provisions of this Section 9 are applicable only to Optionees who
are employees of the Company. Nothing contained in the Plan or this Option shall
be construed or deemed by any person under any circumstances to bind the Company
to continue the employment of the Optionee for the period within which this
Option may be exercised. However, during the period of the Optionee's
employment, the Optionee shall render diligently and faithfully the services
which are assigned to the Optionee from time to time by the Board of Directors
or by the executive officers of the Company and shall at no time take any action
which directly or indirectly would be inconsistent with the best interests of
the Company.

     10.  Rights as a Stockholder.
          ----------------------- 

          The Optionee shall have no rights as a stockholder with respect to any
Shares which may be purchased by exercise of this Option unless and until a
certificate or certificates representing such Shares are duly issued and
delivered to the Optionee. Except as otherwise expressly provided in the Plan,
no adjustment shall be made for dividends or other rights for which the record
date is prior to the date such stock certificate is issued.

     11.  Withholding Taxes.
          ----------------- 

          Whenever Shares are to be issued upon exercise of this Option, the
Company shall have the right to require the Optionee to remit to the Company an
amount sufficient to satisfy all Federal, state and local withholding tax
requirements prior to the delivery of any certificate or certificates for the
Shares. The Company may agree to permit the Optionee to authorize the Company to
withhold Shares of Common Stock purchased upon exercise of the Option to satisfy
the above-mentioned withholding requirement; provided, however, no such
agreement may be made by an Optionee who is an officer or director within the
meaning of Section 16 of the Securities Exchange Act of 1934, as amended, except
pursuant to a standing election to so withhold Shares of Common Stock purchased
upon exercise of the Option, such election to be made in the form set forth in
Exhibit 2 hereto and to be made not less than six (6) months prior to such
exercise. Such election may be revoked only upon providing six (6) months prior
written notice to the Company.

     12.  Plan Provisions Control.
          ----------------------- 

          In the event of any inconsistency between the provisions of this
Agreement and the provisions of the Plan, the inconsistent provision(s) of this
Agreement shall be superseded by the Plan provision(s) to the extent necessary
to reconcile the inconsistency.

                                      -4-
<PAGE>
 
     IN WITNESS WHEREOF, the Company has caused the Agreement to be executed,
and the Optionee has hereunto set his or her hand, all as of the 6th day of
August, 1996.

                           TO STOCK OPTION AGREEMENT


Gentlemen:

     In connection with the exercise by me of an option to purchase shares of
Common Stock, $.001 par value, of Life Medical Sciences, Inc. (the "Company"), I
hereby acknowledge that I have been informed as follows:

     1.   The shares of Common Stock of the Company to be issued to me pursuant
to the exercise of said option (the "Shares") have not been registered under the
Securities Act of 1933, as amended (the "Securities Act") and, accordingly, must
be held indefinitely unless the Shares are subsequently registered under the
Securities Act, or an exemption from such registration is avail able.

     2.   Routine sales of securities made in reliance upon Rule 144 under the
Securities Act can be made only after the holding period provided by that Rule
has been satisfied, and, in any sale to which that Rule is not applicable,
registration or compliance with some other exemption under the Securities Act
will be required.

     3.   The availability of Rule 144 is dependent upon adequate current public
information with respect to the Company being available and, at the time that I
may desire to make a sale pur suant to the Rule, the Company may neither wish
nor be able to comply with such requirement.

     In consideration of the issuance of certificates for the Shares to me, I
hereby represent and warrant that I am acquiring the Shares for my own account
for investment, and that I will not sell, pledge or transfer the Shares in the
absence of an effective registration statement covering the same, except as
permitted by the provisions of Rule 144, if applicable, or some other applicable
exemption under the Securities Act. In view of this representation and warranty,
I agree that there may be affixed to the certificates for the Shares to be
issued to me, and to all certificates issued hereafter representing the Shares
(until in the opinion of counsel, which opinion must be reason ably satisfactory
in form and substance to counsel for the Company, it is no longer necessary or
required) a legend as follows:

     "The securities represented by this certificate have not been registered
     under the Securities Act of 1933, as amended, and were acquired by the
     registered holder pursuant to a representation and warranty that such
     holder was acquiring the Shares for his own account and for investment,
     with no intention of transfer or disposition of the same in violation of
     the registration requirements of that Act. These securities may not be
     sold, pledged, or transferred in the absence of an effective registration
     statement under such Act, or an opinion of counsel, which

                                      -7-
<PAGE>
 
     opinion is reasonably satisfactory to counsel to the Company, to the effect
     that registration is not required under such Act."

     I further agree that the Company may place a stop transfer order with its
transfer agent, prohibiting the transfer of the Shares, so long as the legend
remains on the certificates repre senting the Shares.

                              Very truly yours,

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


Gentlemen:

     In connection with the exercise by me of an option to purchase shares of
Common Stock, $.001 par value, of Life Medical Sciences, Inc. (the "Company"), I
hereby acknowledge that I have been informed as follow.s

     1.  The shares of Common Stock of the Company to be issued to me pursuant
to the exercise of said option (the "Shares") have not been registered under the
Securities Act of 1933, 1S amended (the "Securities Act") and, accordingly, must
be held indefinitely unless the Shares re subsequently registered under the
Securities Act, or an exemption from such registration is available.

     2.  Routine sales of securities made in reliance upon Rule 144 under the
Securities Act can be made only after the holding period provided by that Rule
has been satisfied, and, in my sale to which that Rule is not applicable,
registration or compliance with some other exemption under the Securities Act
will be required.

     3.  The availability of Rule 144 is dependent upon adequate current public
information with respect to the Company being available and, at the time that I
may desire to make a sale pursuant to the Rule, the Company may neither wish nor
be able to comply with such requirement.

     In consideration of the issuance of certificates for the Shares to me, I
hereby represent and warrant that I am acquiring the Shares for my own account
for investment, and that I will not sell, pledge or transfer the Shares in the
absence of an effective registration statement covering he same, except as
permitted by the provisions of Rule 144, if applicable, or some other applicable
exemption under the Securities Act. In view of this representation and warranty,
I agree that there may be affixed to the certificates for the Shares to be
issued to me, and to all certificates issued hereafter representing the Shares
(until in the opinion of counsel, which pinion must be reasonably satisfactory
in form and substance to counsel for the Company, it is 10 longer necessary or
required) a legend as follows:

     "The securities represented by this certificate have not been registered
     under the Securities Act of 1933, as amended, and were acquired by the
     registered holder pursuant to a representation and warranty that such
     holder was acquiring the Shares for his own account and for investment,
     with no intention of transfer or disposition of the same in violation of
     the registration requirements of that Act. These securities may not be
     sold, pledged, or transferred in the absence of an effective registration
     statement under such Act, or an opinion of counsel, which

                                      -7-
<PAGE>
 
     Opinion is reasonably satisfactory to counsel to the Company, to the effect
     that registration is not required under such Act."

     I further agree that the Company may place a stop transfer order with its
transfer agent, prohibiting the transfer of the Shares, so long as the legend
remains on the certificates representing the Shares.

                              Very truly yours,


Dated: _________________________

                           TO STOCK OPTION AGREEMENT
                           -------------------------


Gentlemen:

     In connection with the exercise by me of an option to purchase shares of
Common Stock, i.001 par value, of Life Medical Sciences, Inc. (the "Company"), I
hereby acknowledge that I ave been informed as follows:

     1.  The shares of Common Stock of the Company to be issued to me pursuant
to the exercise of said option (the "Shares") have not been registered under the
Securities Act of 1933, 1S amended (the "Securities Act") and, accordingly, must
be held indefinitely unless the Shares re subsequently registered under the
Securities Act, or an exemption from such registration is available

     2.  Routine sales of securities made in reliance upon Rule 144 under the
Securities Act can be made only after the holding period provided by that Rule
has been satisfied, and, in any sale to which that Rule is not applicable,
registration or compliance with some other exemption under the Securities Act
will be required.

     3.  The availability of Rule 144 is dependent upon adequate current public
information with respect to the Company being available and, at the time that I
may desire to make a ale pursuant to the Rule, the Company may neither wish nor
be able to comply with such equipment.

     In consideration of the issuance of certificates for the Shares to me, I
hereby represent and warrant that I am acquiring the Shares for my own account
for investment, and that I will not sell, pledge or transfer the Shares in the
absence of an effective registration statement covering the same, except as
permitted by the provisions of Rule 144, if applicable, or some other applicable
exemption under the Securities Act. In view of this representation and warranty,
I agree that there may be affixed to the certificates for the Shares to be
issued to me, and to all certificates issued hereafter representing the Shares
(until in the opinion of counsel, which Opinion must be reasonably satisfactory
in form and substance to counsel for the Company, it is no longer necessary or
required) a legend as follows:

     "The securities represented by this certificate have not been registered
     under the Securities Act of 1933, as amended, and were acquired by the
     registered holder pursuant to a representation and warranty that such
     holder was acquiring the Shares for his own account and for investment,
     with no intention of transfer or disposition of the same in violation of
     the registration requirements of that Act. These securities may not be
     sold, pledged, or transferred in the absence of an effective registration
     statement under such Act, or an opinion of counsel, which

                                      -7-
<PAGE>
 
     Opinion is reasonably satisfactory to counsel to the Company, to the effect
     that registration is not required under such Act."

     I further agree that the Company may place a stop transfer order with its
transfer agent, prohibiting the transfer of the Shares, so long as the legend
remains on the certificates representing the Shares.

                              Very truly yours,


Dated: _______________
