ITEM  1.          DESCRIPTION OF BUSINESS

General

       Enamelon, Inc. (the "Company") develops and markets over-the-counter oral
care products that help stop cavities before they begin. The Company's products
are based on proprietary formulations and technologies that have been shown in
laboratory and human studies to enhance remineralization of tooth enamel and to
prevent early stage tooth decay. The Company's toothpastes contain the active
ingredient sodium fluoride in a formulation with calcium and phosphate ions, to
enhance the remineralization of tooth enamel. The Company launched its initial
product, Enamelon(R) all-family toothpaste, in test markets in March 1997 and
began the product's national introduction in the first quarter of 1998. The
Company expects to launch Enamelon(R) Calcium Whitening System toothpaste, its
second product, nationally in the second quarter of 1999.

       The Company holds licenses from the American Dental Association Health
Foundation to use patented technology relating to a method for oral use of
various amorphous calcium phosphate compounds that enhance the natural activity
of fluoride to prevent tooth decay. The ADAHF has granted the Company the
following licenses:

o      exclusive United States and foreign licenses to develop, manufacture and
       market toothpaste and chewing gum and other food and confectionery
       products using the ADAHF's patented technology and

o      a non-exclusive international license covering oral spray, mouth rinse,
       professional gel products and all other products not covered by the
       Company's exclusive licenses using the ADAHF's patented technology.

The ADAHF has also granted SmithKline Beecham Corp. a non-exclusive
international license of the ADAHF's patented technology covering the same
products as the Company's non-exclusive international license. SmithKline also
obtained from the ADAHF an exclusive United States license covering oral spray,
mouth rinse, professional gel products, and all other products not covered by
the Company's exclusive United States license. The Company is required to pay
the ADAHF royalties under its license agreements.

       The Company itself has developed patented and other proprietary
technologies relating to the prevention of tooth decay before it begins. Through
February 1999, it had been granted eleven patents, nine United States patents
for methods and materials that supply soluble calcium and phosphate salts to
teeth to enhance remineralization, and two patents for its dual-chamber tube,
which is used to dispense Enamelon(R) toothpastes. In addition, the Company has
patent applications pending in the United States with respect to additional
aspects of its proprietary technology and has filed similar patent applications
that are also pending in foreign jurisdictions.

       The Company's objective is to become a leading marketer of a variety of
oral care products based on the ADAHF's patented technology and the Company's
own proprietary technology (together, the "Enamelon Licensed and Proprietary
Technologies").



<PAGE>

The significant events in the Company's progress to date include the following:

o    In 1992, the Company was organized and received from the ADAHF
     exclusive United States and foreign licenses for toothpaste and chewing gum
     and other food and confectionery products, and a non-exclusive
     international license for products not covered by the exclusive licenses.
     See "ADAHF Patents and Licenses."

o    In January 1995, the Company conducted successful laboratory tests
     of a prototype formulation using the Enamelon Licensed and Proprietary
     Technologies at the Oral Health Research Institute of Indiana University.

o    In June 1996, the Company commenced preliminary intra-oral and
     clinical studies of its toothpaste intended to establish additional
     advertising claims.

o    In October 1996, the Company completed its initial public offering
     of 1,700,000 shares of its common stock at $7.00 per share, receiving net
     cash proceeds of approximately $10.4 million.

o    In November 1996, the Company was granted its first patent and has been
     granted 10 additional patents through February 1999, all of which
     relate to its proprietary technology. See "Patents, Trademarks and
     Other Proprietary Information."

o    In March 1997, the Company initiated marketing activities for
     Enamelon(R) all-family toothpaste in selected United States markets.

o    In June 1997, the Company completed a private placement of
     1,080,000 shares of common stock at $13.00 per share, receiving net cash
     proceeds of approximately $13.1 million.

o    In October 1997, the Company completed a public offering of
     1,725,000 shares of common stock at $16.50 per share, receiving net cash
     proceeds of approximately $26.3 million.

o    During the first quarter of 1998, the Company began to introduce
     Enamelon(R) all-family toothpaste nationally. In April 1998, it launched a
     nationwide television and print advertising campaign.

o    In September 1998, the Company received approval to market Enamelon(R)
     all-family toothpaste in Canada.

o    In December 1998, the Company completed the private placement of
     500 shares of series B convertible preferred stock, receiving gross cash
     proceeds of $5,000,000.

o    In February 1999, the Company hired Kim Hardingham as its President
     and Chief Operating Officer, and in July 1998, it hired Louis Machin as its
     Vice President-Sales.

         During the second quarter of 1999, the Company expects to launch
Enamelon(R) Calcium Whitening System toothpaste to supermarkets, drug chains and
mass merchandisers. In addition, the Company is continuing to conduct laboratory
and intra-oral and human clinical studies to establish support for additional
advertising claims directed to both consumers and the dental community.


                                        2

         The worldwide toothpaste market is estimated to exceed $5.0 billion in
annual retail sales. Annual United States toothpaste sales in 1998 have been
estimated at $1.6 billion and are projected to reach $2.0 billion by 2003. Over
the last five years, the toothpaste market has become segmented, as new,
premium-priced products offering benefits such as tartar control or whitening or
containing ingredients such as baking soda have steadily attracted consumers
away from older, more mature products.

Technology

         Every time people eat, their teeth lose small amounts of calcium and
phosphate, the major structural ingredients of tooth enamel. This
demineralization process begins with the formation of plaque on and between
teeth. Plaque is a soft, sticky film that contains a high concentration of
bacteria that causes an oral disease called caries, which causes tooth decay.
Demineralization continues when acids produced by the cariogenic bacteria in
plaque dissolve and remove small amounts calcium and phosphate from the enamel
on the outside of the tooth and, often, from the tooth's dentin, which is under
the enamel.

         Saliva naturally contains microscopic, electrically-charged calcium and
phosphate particles called ions that fight this demineralization process.
Remineralization occurs when the calcium and phosphate lost during
demineralization are replaced with the calcium and phosphate ions dissolved in
saliva. The presence of fluoride in the saliva is also known to facilitate
remineralization of calcium and phosphate. In the 1950's, scientists determined
that adding fluoride as the active ingredient to toothpaste improves
remineralization. As an active ingredient, fluoride is responsible for the
therapeutic remineralizing activity of fluoride toothpaste. However,
remineralization by fluoride toothpastes is limited by the amounts of calcium
and phosphate ions normally present in the saliva. If the daily amount of
demineralization is not balanced by the daily amount of remineralization, there
will be a net mineral loss from the tooth. If this process continues, the tooth
structure will collapse and a cavity will form. Only a dentist can repair a
cavity.

         The Company's toothpastes simultaneously supply the active ingredient,
sodium fluoride, and assured concentrations of ions of the inactive ingredients
calcium and phosphate in a dissolved, or soluble, form during brushing. The
Company's research studies have demonstrated that Enamelon(R) toothpaste
enhances remineralization with a high level of fluoride, calcium and phosphate
uptake and that the tooth structure has been strengthened and hardened. This
makes the tooth less porous and more resistant to attacks by acids from
decay-causing bacteria.

Strategy

         The Company's objective is to develop a variety of oral care, chewing
gum and other food and confectionery products that are based on the Enamelon
Licensed and Proprietary Technologies and help prevent tooth decay at its
earliest stage. The Company has developed a strategic plan to accomplish this
goal. The Company's primary strategies are to:

o    Continue Marketing and Expand Distribution of Enamelon(R)
     toothpaste. The Company intends to continue executing its marketing and
     distribution programs to expand distribution of Enamelon(R) all- family
     toothpaste to drugstores, mass merchandisers, and supermarkets.

o    Launch Enamelon(R) Calcium Whitening System Toothpaste and Other
     New Products. The Company is currently focusing on the launch of its
     Enamelon(R) Calcium Whitening System toothpaste in the second quarter of
     1999. The Company has an aggressive new products program underway and
     expects to introduce several line extensions that are consistent with
     market trends and exploit the

                                        3

<PAGE>

     Company's remineralization technology. These new products include a
     toothpaste for sensitive teeth and a gel toothpaste.

o    Continue Marketing to Dental Professionals. The Company's
     goal is to continue to build awareness of the Enamelon
     Licensed and Proprietary Technologies and its products in
     the dental community. The Company will continue its
     efforts in educating the dental community regarding the
     proven therapeutic benefits of Enamelon(R) toothpaste.

o    Broaden Product Claims. The Company believes that a broadened and
     heightened understanding of the technology required for effective
     remineralization of tooth enamel will lead to a stronger competitive
     position. It is conducting intra-oral and human clinical studies to
     establish additional promotional claims to be directed to both consumers
     and the dental community.

o    Obtain the ADA Seal of Approval. The Company expects to file an
     application for the American Dental Association Seal of Approval for
     Enamelon(R) all-family toothpaste in the second quarter of 1999. It
     believes that the ADA Seal of Approval will enhance the standing of
     Enamelon(R) all-family toothpaste with both the dental community and
     consumers.

o    Collaborate with Corporate Partners in Certain Product Areas and
     International Markets. The Company intends to seek domestic and
     international strategic alliances with consumer product companies that will
     assist in the marketing and manufacturing of oral care products outside of
     the United States.

o    Capitalize on Additional Commercial Applications. The Company
     believes that products such as chewing gum, mouthwash, dental floss,
     lozenges, mints and professional products may provide benefits similar to
     those of its toothpastes and represent large potential markets for the
     application of the Enamelon Licensed and Proprietary Technologies.

Products

         The Company has introduced toothpaste as its initial product line. The
Company also is exploring application of the Enamelon Licensed and Proprietary
Technologies to food and confectionery products, which it intends to develop
after the national introduction of Enamelon(R) all-family toothpaste,
Enamelon(R) Calcium Whitening System toothpaste and various line extensions.

 Toothpastes

         All-Family Toothpaste. The Company's introductory product, Enamelon(R)
all-family fluoride toothpaste, provides the active ingredient sodium fluoride
and is formulated to help stop cavities before they begin and to enhance
remineralization of tooth enamel. Product development activities for the
Company's all-family toothpaste were completed at the end of 1996. The Company
introduced this toothpaste into test markets consisting of approximately 5% of
United States households in early 1997. During 1998, the Company successfully
launched Enamelon(R) all-family toothpaste nationally.

         Toothpaste Line Extensions. An integral part of building the
Enamelon(R) brand involves product line extensions, which help create a greater
retail shelf presence. The Company chose Enamelon(R) Calcium Whitening System
toothpaste, which both whitens and strengthens tooth enamel, for its first line
extension. It expects to launch this product through a national media campaign
in the second quarter of

                                        4

<PAGE>

1999. Other toothpaste line extensions, such as a toothpaste for sensitive teeth
and a gel toothpaste, are expected to be introduced as product development is
completed.

Dual-Chamber Tube

         In order to dispense its toothpaste products, the Company has developed
a patented dual- chamber toothpaste tube that simultaneously dispenses two
formulations. The tube's dual chambers maintain separation between the two
component formulations until they are dispensed onto a toothbrush. Unlike
presently used dual-chamber toothpaste dispensing systems, which employ
expensive pumps, the Company's tube was designed to be filled with conventional
high-speed tube filling equipment, thus making the cost lower than other
dual-chamber toothpaste dispensing systems. The dual-chamber tube may also have
commercial applications outside of the toothpaste field.

Additional Potential Products

         The Company has initiated product development activities for a range of
new products based on the Enamelon Licensed and Proprietary Technologies. In
particular, the Company has targeted the chewing gum market, because it believes
that chewing gum represents an attractive delivery system for the Enamelon
Licensed and Proprietary Technologies in a market that has been estimated to
exceed $2.0 billion of United States retail sales in 1998. The Company is
developing a prototype chewing gum and is exploring strategic alliances with
major confectionery manufacturers for marketing, sales and distribution of a
chewing gum in the United States and international markets. The Company believes
that a chewing gum formulated using the Enamelon Licensed and Proprietary
Technologies may reduce the demineralizing effects of plaque acids through the
increased stimulation of saliva and by adding calcium and phosphate ions to
saliva. Accordingly, the Company believes that its proposed chewing gum may be a
beneficial supplement to brushing. FDA regulations, however, may limit claims
that the Company can make for its proposed chewing gum.

         The Company also believes that the use of the Enamelon Licensed and
Proprietary Technologies in other food and confectionery products, such as
lozenges or mints, can provide benefits similar to those in the Company's
toothpaste and other proposed oral care products. The Company has begun to
evaluate the possible uses of the Enamelon Licensed and Proprietary Technologies
in these products and intends to explore such applications following the
commercialization of its toothpastes.

         The Company is also pursuing the development of other oral care
products, including mouthwash and professional gels for foreign markets and
professional dentifrices for both the domestic and foreign markets. The Company
believes that these products will compliment its existing products and broaden
its position in the oral care category.

Marketing

         The Company's national marketing strategy aims to create brand
awareness and generate trial among consumers by promoting its proprietary
technology and the therapeutic benefits of its products. To differentiate its
products from other competing toothpaste and oral care products, the Company has
positioned them to emphasize their advanced technologies and remineralizing and
whitening qualities. The Company uses daytime and primetime television
advertising, national spot radio, consumer sampling programs and distribution of
coupons by mail and Sunday newspaper supplements to educate consumers and create
demand.


                                        5

<PAGE>

         The Company is also targeting the dental profession to create awareness
of its remineralization technology and products. To implement this strategy, the
Company frequently places technical articles in professional journals, attends
professional conventions and develops direct response programs directed to
dentists and dental hygienists for distribution of patient samples. The Company
believes that these programs have been well received and that the long-term
benefits of professional endorsements for its products are significant. One
independent awareness and usage study showed that awareness of Enamelon(R)
toothpaste among dental professionals is positive. Over 80% of all dentists
surveyed were aware of Enamelon(R) toothpaste, and over 70% rated Enamelon(R)
toothpaste as a good, very good or excellent dentifrice.

Markets and Customers

         Toothpaste is generally sold to consumers by supermarkets and other
food stores, mass merchandisers and drug stores. Supermarkets accounted for
approximately 47% of all U.S. toothpaste sales in 1998, while mass merchandisers
accounted for 34% and drug stores accounted for 19%. The Company uses
independent brokers to make sales of Enamelon(R) toothpastes to these retailers.
In 1998 and early 1999, the Company hired a Vice President-Sales and three
regional sales managers to coordinate and manage the activities of the brokers
that sell Enamelon(R) toothpastes. In the four weeks ended January 3, 1999, the
Company had distribution of Enamelon(R) all-family toothpaste in 89% of all drug
stores, 63% of all supermarkets, and 67% of all mass merchandisers.
Representative customers are set forth below.

BJ's Wholesale Club          Eckerd Drug          Publix Supermarket Inc.

No customer accounted for more than 10% of the Company's sales in 1998.

Research and Development

         The Company operates a research and development facility in Cranbury,
New Jersey. The Company's research and development relate to technology,
formulation, flavor, packaging and process development, and stability and safety
evaluations. In addition, the Company sponsors research related to efficacy
testing at leading universities and outside research facilities.

         Before the market introduction of Enamelon Licensed and Proprietary
toothpaste, the Company conducted laboratory studies to assess the effectiveness
of the Enamelon Licensed and Proprietary Technologies. The studies generally
demonstrated that prototype toothpaste formulations using the Enamelon Licensed
and Proprietary Technologies resulted in increased hardness and fluoride uptake
over that obtained by the prevailing industry standard. One laboratory study
demonstrated that daily treatment with a prototype formulation of Enamelon(R)
toothpaste over a two-week period reduced interproximal

                                        6

<PAGE>

lesions, spots between teeth where tooth decay was beginning. While the
formulations used in the foregoing tests differ from the final formulation of
Enamelon(R) toothpaste, similar ingredients are used in the final formulation,
and the Company believes that the results of similar laboratory studies with the
final formulation would not differ significantly from those described above.

         The Company has additional research supporting the current formulation
of Enamelon(R) all-family toothpaste. Dental research scientists have published
24 studies on Enamelon(R) toothpaste at international dental research meetings.
The Company believes that approximately ten peer-reviewed articles will also be
published in a special edition of the Journal of Clinical Dentistry. This
research serves as a source of information that demonstrates to the dental
profession the therapeutic benefits of Enamelon(R) toothpaste. The Company also
expects to use the results of these studies to expand advertising claims for its
products directed to consumers.

         The Company's research team is preparing an application to the ADA for
its Seal of Approval for Enamelon(R) all-family toothpaste, which it expects to
submit in the second quarter of 1999. The Company believes that the ADA Seal of
Approval will enhance the standing of Enamelon(R) all-family toothpaste among
the dental community as well as consumers. There can be no assurance, however,
that the ADA will approve the Company's application and award its Seal of
Approval to Enamelon(R) all-family toothpaste.

         Notwithstanding the foregoing, the results of the Company's studies to
date are not necessarily indicative of the results that will be obtained in
future studies. Some human studies are being conducted under substantially
different conditions from those of the prior tests, and there can be no
assurance that these studies will support additional advertising claims,
including comparative claims. While studies to date support the claims being
made for Enamelon(R) toothpaste, there can be no assurance that additional
studies will be supportive, that additional claims can be made for the product,
or that the Enamelon Licensed and Proprietary Technologies can be applied in
other oral care products. Furthermore, the Company may not be able to sell some
of its other proposed products to the public in compliance with the U.S. Food
and Drug Administration Monograph described below under "Government Regulation".
Products not covered by the Anticaries Monograph may be subject to other FDA
requirements, which could require additional testing and could limit the claims
that could be made for those products.

         The current focus of the Company's toothpaste development program is on
innovative toothpaste line extensions, such as Enamelon(R) Calcium Whitening
System toothpaste. The Company has also begun to conduct research on methods for
employing the Enamelon Licensed and Proprietary Technologies in other oral care
products, such as chewing gum, that it will seek to market. However, the
formulations of the Company's toothpaste products and other proposed products
constantly change as dictated by consumer testing and research and development.

         From the Company's inception to December 31, 1998, the Company spent
approximately $8,691,329 on its research and development activities, including
$3,215,831 for the year ended December 31, 1998. The Company expects the level
of its research and development expenses to increase in the future.

Manufacturing

         The Company's present strategy is to outsource the manufacture of its
toothpastes to experienced, FDA-registered contract manufacturers. The Company
believes that outsourcing provides greater long-term flexibility, requires a
lower initial capital investment in facilities, and avoids recruiting, training
and supervising a large manufacturing staff. The current contract manufacturer
for the Company's toothpaste is West Pharmaceutical Services, Inc.

                                        7

<PAGE>

         The Company's patented dual-chamber system required the design of
specialized assembly and filling equipment. Working closely with equipment
manufacturers, the Company modified existing commercial equipment and completed
new designs where required. The Company's tooling is currently used to produce
the tube shoulders and the plastic divider that separates the two formulations
in the Company's toothpastes. The Company owns all of the manufacturing
equipment and tooling, which is used by its contract manufacturers at their
facilities.

         The Company purchases conventional toothpaste tubes, decorated with the
Enamelon(R) design, and converts them into the dual-chamber system by inserting
the custom-designed divider into the tube. This sub-assembly work is performed
by several contract manufacturers, other than West, on high speed insertion and
sealing equipment specifically designed for this task. The tubes, ready for
filling, are then shipped to West.

         The Company and West have developed a dedicated, state-of-the-art
production line in West's Lakewood, N.J. facility. West receives raw materials
ordered by the Company and is responsible for compounding these ingredients and
filling them on Company-owned, high-speed tube filling and cartoning production
lines. In addition to West's quality control inspections, raw materials and
finished product are closely monitored by Company quality assurance personnel to
insure the finished product meets all required specifications.

         The Company currently has three manufacturing lines available for
operation, which have a total annual capacity of approximately 30 million tubes.
In addition, West has installed blending and storage facilities and has created
a filling area to support the Company's packaging and filling equipment. The
Company believes that the new blending equipment will provide sufficient
capacity, in a highly cost effective manner, to meet anticipated current and
future needs.

         The Company believes that its ownership of manufacturing equipment and
tooling will provide greater long-term flexibility, permitting it to change
manufacturers or even to commence its own manufacturing operations. The Company
has identified other FDA-registered manufacturers that it can use if West's
capacity becomes insufficient to satisfy demand or if West otherwise becomes
unavailable to manufacture the product.

         The Company uses one principal supplier for toothpaste tubes, cartons
and each of the ingredients used in formulating Enamelon(R) toothpastes. Those
products, however, are generally available from a number of other suppliers. The
Company has identified several other suppliers of those items, which it can use
if its principal suppliers become unavailable or their capacity is insufficient
to satisfy the Company's demand. Although the Company maintains inventories of
the supplies required to manufacture Enamelon(R) toothpastes, shortages of
materials or changing suppliers could result in delays in manufacturing,
increased costs and shortages of the Company's products.

         In connection with the foreign marketing of its toothpaste products, as
well as domestic and foreign marketing of its other proposed products, the
Company may seek to sublicense the Enamelon Licensed and Proprietary
Technologies to, or enter into joint ventures or strategic partnerships with,
major consumer product companies or other third parties. Manufacturing
arrangements for those products are likely to be reflected in any agreements
establishing the relationships and may place primary manufacturing
responsibilities on others.

         The Company operates a pilot plant facility in Cranbury, New Jersey,
that has limited blending and filling capacity. Its purpose is to develop
manufacturing and filling methods and procedures, prior to full

                                        8

<PAGE>

scale manufacturing. In addition, the pilot plant will be used to produce
products for research studies and develop new products using the Enamelon
Licensed and Proprietary Technologies.

Competition

The United States toothpaste industry is dominated by the following brands:

o         Procter & Gamble Co.'s Crest

o         Colgate-Palmolive Company's Colgate

o         SmithKline's Aquafresh

o         Chesebrough-Ponds USA Co.'s Mentadent

o         Church & Dwight Co., Inc.'s Arm & Hammer Dental Care

o         Block Drug Co., Inc.'s Sensodyne

The industry is led by Colgate-Palmolive Co., which established its position as
the market leader during 1998.

         Although the toothpaste market is mature, in recent years new products
have captured market share from established brands. Market share gains have been
achieved by higher priced, more therapeutically oriented new products with
unique marketing positions. Consequently, the Company believes that its focus on
remineralization of tooth enamel and its proprietary technology will capture
consumer and professional interest.

         If the Company attempts to market a chewing gum using the Enamelon
Licensed and Proprietary Technologies, then it will be entering another highly
competitive industry. The chewing gum market in the United States is dominated
by several major competitors, including Wm. Wrigley Jr. Co., Warner-Lambert
Company and RJR Nabisco, Inc. In addition, Church & Dwight recently introduced
Arm & Hammer Baking Soda Chewing Gum, which it claims will aid in removing
plaque from teeth. This chewing gum is being displayed on retailers' shelves
with oral care products rather than other chewing gums. The Company believes
that its other competitors will also introduce chewing gums that make oral-care
claims. Accordingly, competition in this category should become even stronger in
the future.

         The Company also intends to compete in other food and confectionery
categories. If the Company sublicenses the Enamelon Licensed and Proprietary
Technologies to or enters into joint ventures or strategic partnerships with
major consumer products companies for any of those products, it may be aligning
itself with one or more of its major competitors instead of competing with them.
The Company will also be required to comply with applicable FDA regulations,
which may limit the claims that may be made for those products and restrict the
Company's ability to compete effectively.

         Additionally, the Company is pursuing the development of its rights to
manufacture and market products using the Enamelon Licensed and Proprietary
Technologies, including mouth rinses and professional gels, outside of the
United States. The international markets for these products are in many ways
similar to the United States markets in that consumers are becoming increasingly
aware of the importance of oral hygiene. Product innovation with emphasis on
therapeutic benefits is continuous. The Company's competition in markets outside
the United States will vary by product and from country to

                                        9

<PAGE>

country. However, in general, such markets tend to be highly competitive and
dominated by large multinational and domestic corporations. The Company does not
presently have the resources necessary to compete on a global scale and intends
to seek corporate partners and/or negotiate license agreements with companies
that have the resources to compete effectively in foreign markets. Although the
Company will attempt to form strategic alliances with global companies, it may
also seek to negotiate on a country-by-country basis with major regional
companies, as necessary or appropriate.

ADAHF Patents and Licenses

         The patent rights licensed to the Company by the ADAHF together with
the Company's own patents are material to the Company's business. The ADAHF
patent rights licensed to the Company relate to five United States patents.
Three of the issued patents relate to formulations, applicable to toothpastes,
chewing gums, mouth rinses and professional gels, containing or capable of
producing Amorphous Calcium Phosphate, Amorphous Calcium Carbonate Phosphate and
Amorphous Calcium Phosphate Fluoride, as well as the application of these
formulations to teeth. The other two patents relate to Amorphous Calcium
Phosphate Carbonate Fluoride and Amorphous Calcium Fluoride compounds and other
technology not covered in the first three United States patents.

United States License Agreement

         In April 1998, the Company entered into an amendment to its License
Agreement with the ADAHF, which was originally signed in June 1992 and was
subsequently restated and amended and further amended in June 1995. The License
Agreement, as amended, grants the Company a fully-paid, exclusive United States
license to manufacture and sell toothpastes and chewing gum and other food and
confectionery products ("Exclusive Products") using the ADAHF's patented
technology. Under the License Agreement, the Company is required to pay a fixed
annual royalty of $400,000 through 2008 with respect to all Company sales of
Exclusive Products up to $100 million in that year and an additional fixed
royalty of $200,000 with respect to all Company sales of Exclusive Products
exceeding $100 million in that year. Company sales of all Exclusive Products are
included in calculating the royalty, regardless of whether they use the ADAHF's
patented technology. The Company has the right to sublicense or assign all or
any part of its rights under the License Agreement, but will continue to be
liable for payment of the fixed royalties regardless of such sublicense or
assignment. The term of the License Agreement expires upon the last to expire of
the ADAHF's patents, including any continuations, divisions, reexaminations,
extensions or releases thereof.

         The License Agreement provides that improvements that are used with or
that require use of Exclusive Products that embody material claimed in the
ADAHF's patents, as well as any improvements and inventions that are made
jointly by the Company and the ADAHF that do not relate to remineralization or
commercialization of Exclusive Products or of the subject matter of the ADAHF's
patents, will be owned by the ADAHF and licensed to the Company at no additional
cost. The Company has the right to veto the ADAHF's grant to third parties of
licenses relating to improvements and inventions that are developed in part by
the Company.

         The ADAHF's patents may claim the effectiveness of ingredients that do
not fall under the FDA's toothpaste Monograph. However, Enamelon(R) toothpaste
does not rely on those ingredients as active ingredients, but relies only on
sodium fluoride as the sole active ingredient.

 Foreign License Agreement

         In April 1998, the Company entered into an amendment to its Foreign
License Agreement with the

                                       10

<PAGE>

ADAHF, which was originally signed in November 1992 and subsequently restated
and amended and further amended in June 1995. The Foreign License Agreement
grants the Company an exclusive license to manufacture and sell Exclusive
Products using technology that is the subject matter of foreign patent
applications filed by the ADAHF in specified foreign countries. It also grants
the Company the non-exclusive right to manufacture and sell in those countries
other products using that technology, including oral sprays, mouth rinses and
professional gels ("Non-Exclusive Products"). The Company's payment of royalties
under the License Agreement described above will also constitute a fully-paid
license under the Foreign License Agreement with respect to the Exclusive
Products. Under the Foreign License Agreement, the Company is required to pay a
royalty of 7% of net sales of Non-Exclusive Products using the licensed
technology. The royalty for Non-Exclusive Products will be reduced to 4% if
sales are made by an entity that enters into a joint venture with the Company
and bears the costs of prosecution of foreign patent applications. The Foreign
License Agreement expires upon the earlier of the termination of the License
Agreement or the expiration of the last to expire of any foreign patent licensed
under the Foreign License Agreement or the abandonment or lapse of all foreign
patents and applications. The ADAHF may abandon or permit the lapse of all
foreign patent applications and foreign patents and retains the authority to
make all final decisions controlling patent prosecution and maintenance. If the
ADAHF abandons or permits the foreign patent applications or foreign patents to
lapse, competitors would be free to manufacture and sell products using the
ADAHF's patented technology that could compete with the Company's toothpaste or
other proposed products in those countries.

         During the term of the Foreign License Agreement, the Company has an
option and right of first refusal to license future patent applications made and
patents issued with respect to ADAHF's patent rights in those jurisdictions not
presently covered by the License Agreement or the Foreign License Agreement. If
the Company exercises its rights, the license will be exclusive with respect to
the Exclusive products. Before granting a license to a third party for those
products in a new jurisdiction, the ADAHF must first notify the Company, which
will then have the right to obtain a license for that jurisdiction on terms
consistent with the Foreign License Agreement. If the Company does not exercise
its option and the ADAHF does not license its patent rights in that jurisdiction
to a third party, the Company will have a continuing option to license the
ADAHF's patent rights in that jurisdiction on terms consistent with the Foreign
License Agreement until the ADAHF licenses those rights to a third party.

         The Company presently is the licensee under the Foreign License
Agreement of certain ADAHF Patent Rights under patent applications pending in
six foreign jurisdictions. Patent applications made in certain other foreign
jurisdictions, however, have been abandoned, and the other pending foreign
patent applications with respect to the ADAHF's patent rights may also be
abandoned. Nevertheless, the Company believes that its filing of patent
applications with respect to the Company's own patent rights in any foreign
jurisdictions in which patent applications have been abandoned and the
subsequent issuance of patents to the Company in those jurisdictions will be
adequate to preclude other manufacturers from using the Company's remineralizing
technologies to manufacture and sell oral care products in those jurisdictions.
It is possible, however, that patents will not issue in those jurisdictions or
that manufacturers outside of the United States will infringe the Company's
patent rights or challenge their validity.

         The License Agreement and the Foreign License Agreement provides that
the Company may assign or sublicense its rights under its licenses with respect
to the Exclusive Products without the consent of the ADAHF, provided that the
Company will continue to remain liable for payment of royalties under the
License Agreement. In addition, the ADAHF has waived any claim to ownership
rights in any of the Company's patents, and the Company has agreed not to sue
the ADAHF or any licensee of the ADAHF licensed to use the ADAHF patents for
infringement of the Company's patents, unless the infringement constitutes a
beach of the Company's exclusive license under the two license agreements.
Finally, the License Agreement and Foreign License Agreement are both subject to

                                       11

<PAGE>



o        licenses granted to the United States government, which are not 
         transferable for non-commercial purposes and

o        rights retained by the ADAHF to make and use its inventions for
         research and testing, but not to sell or use them commercially in
         fields licensed exclusively to the Company.

         The ADAHF has made no representation or warranty, express or implied,
with respect to the efficacy or possible commercial exploitation of the
Company's proposed products.

ADAHF Licenses to SmithKline

         The Company was notified in July 1995 that the ADAHF had entered into a
license agreement with SmithKline for exclusive rights in the United States for
oral sprays, mouth rinse, professional gels and all other products using the
ADAHF's patented technology, except toothpastes, chewing gum and other food and
confectionery products. The ADAHF also granted SmithKline a non-exclusive
license to manufacture and sell those products in foreign jurisdictions where
the ADAHF had filed patent applications for its patented technology.
SmithKline's rights under that license are co-extensive with the non-exclusive
rights granted to the Company under the Foreign License Agreement.

         Since SmithKline has substantially greater financial and other
resources than those of the Company, the Company may be limited in its ability
to compete effectively with SmithKline outside of the United States, unless the
Company enters into a strategic alliance with another company having financial
and other resources comparable to those of SmithKline.

Patents, Trademarks and Other Proprietary Information

Patents

         The Company has been granted nine United States patents relating to
methods and materials that supply soluble calcium and phosphate salts to teeth
to enhance remineralization, and two patents relating to its dual-chamber
toothpaste tube, which is used to dispense Enamelon(R) toothpaste. In addition,
the Company has 10 patent applications pending in the United States with respect
to various aspects of its proprietary technologies. it also has patent
applications pending in foreign jurisdictions such as the PCT countries, which
include Canada, Japan, Belgium, France, Germany, the United Kingdom, the
Netherlands, Australia, and Sweden, among others, and India. The issued patents
and the patent applications relate to the Company's remineralization technology
as it could be applied to a broad range of oral care and food products,
including toothpaste, mouth rinse, chewing gum, lozenges, and professional
treatments. The Company can give no assurance that patents will issue on the
pending patent applications. It is also possible that if patents do issue, the
claims will not be of sufficient scope to prevent competitors from marketing
products that are similar to the Company's toothpaste or other proposed
products.

         The Company is not aware of the existence of any challenges to the
validity of its patents or of any claim made by a third party of patent
infringement with respect to Enamelon(R) toothpaste. The Company cannot
accurately predict, however, whether such challenges or claims will be asserted
in the future.


                                       12

<PAGE>

Trademarks

         The Company intends to protect the names of certain of its products and
formulations by registration of its trademarks, where appropriate, both in the
United States and in foreign countries.

         The Company has filed applications in the United States Patent and
Trademark Office to register the word mark Enamelon(R) on the Principal Register
for toothpaste, chewing gum, certain confection products, and various oral care
products, such as medicated mouth washes and professional dental gels. The
registration covering toothpaste was issued in late August 1997. The
applications covering chewing gum, confection and oral care products have been
allowed, subject to use of the mark. The Company has also registered or applied
to register the Enamelon(R) mark for toothpaste, chewing gum, certain
confectionery products and various oral care products in certain foreign
countries. It is possible that prior registrations and/or uses of the mark (or a
confusingly similar mark) may exist in one or more countries, in which case the
Company might thereby be precluded from registering and/or using the Enamelon(R)
mark in such countries.

         The Company has also filed applications to register the trademarks
FLUOREMIN and LIQUID CALCIUM and its stylized "E" logo in the United States and
Canada. The United States registration for FLUOREMIN was issued in late July
1997. In addition, the Company is using or considering other trademarks and has
registered or filed applications to register certain of those marks in the
United States and for Canada.

         The Company is not aware of any third-party challenges to the validity
of its trademarks, trademark registrations, or trademark applications (other
than through pending foreign office actions), or of any claim by a third party
of trademark infringement with respect to its products, marks, registrations or
applications. No assurance can be given, however, that such challenges or claims
will not be asserted in the future.

Proprietary Information

         Much of the Company's technology is dependent upon the knowledge,
experience and skills of key scientific and technical personnel. To protect
rights to its proprietary know-how and technology, Company policy requires all
employees and consultants to execute confidentiality agreements that prohibit
the disclosure of confidential information to anyone outside the Company. These
agreements also require disclosure and assignment to the Company of discoveries
and inventions made by such persons while devoted to Company activities. There
can be no assurance that these agreements will adequately protect the company's
proprietary information since:

o         employees or others may breach their confidentiality agreements

o         the Company may not have adequate remedies for any such breach

o         the Company's trade secrets may otherwise become known or be 
          independently developed by competitors.


                                       13

<PAGE>

Government Regulation

         The FDA regulates the Company's toothpastes as non-prescription drugs,
also known as over-the-counter drugs. The Federal Food, Drug, and Cosmetic Act
and the FDA's regulations permit a manufacturer to sell a non-prescription drug
if it is formulated, labeled and tested in accordance with an FDA monograph or
if the FDA has approved a New Drug Application for the drug. FDA monographs
establish those active ingredients that are generally recognized as safe and
effective at specified levels for specified uses and prescribe labeling
requirements. Any non-prescription drug that does not comply with an applicable
FDA monograph may lawfully be marketed if the FDA has approved an NDA. Because
it is time consuming and costly to obtain FDA approval of an NDA, most
manufacturers of non-prescription drugs attempt to market them under an FDA
monograph.

         The FDA has published a final Monograph, Anticaries Drug Products for
Over-the-Counter Human Use, the category of over-the-counter drug products
covering the Company's toothpastes. The Monograph establishes conditions under
which non-prescription drug products that aid in the prevention of dental caries
or cavities are generally recognized as safe and effective and not misbranded.
The Company has conducted the studies required by the Monograph and is relying
on it to sell Enamelon(R) toothpastes to the public. Notwithstanding that
reliance, the FDA could claim that the Company's toothpastes do not satisfy the
conditions of the Monograph. In that case, the Company could be required to
modify the formulation or labeling or to submit an NDA.

         Although the Company intends to make only such labeling claims as the
Monograph permits in order to avoid the substantial expense and time required to
receive FDA approval of an NDA, it may decide to submit an NDA with the FDA in
order to make further claims not covered by the Monograph. If the Company
decides to make such additional claims, it may seek strategic partners to assist
in the financing of the NDA process. Further, the Company may not have
sufficient financing or other resources available to complete the NDA process,
and even assuming that such financing and resources are available, the FDA may
not approve the NDA. Future drug products with intended uses other than or in
addition to caries prevention, such as a toothpaste for sensitive teeth, may be
subject to different FDA monographs or may require an NDA.

         The FDA also regulates manufacturing of oral care drug products. Each
domestic drug product manufacturing facility must be registered with the FDA.
Each manufacturer must inform the FDA of every drug product it has in commercial
distribution and keep its list updated. Domestic manufacturing facilities are
required to comply with the FDA's Good Manufacturing Practices regulations and
are subject to at least biennial FDA inspection. Accordingly, to the extent that
the Company uses contract manufacturers, such manufacturers must be in
compliance with all FDA requirements.

         The Company is also subject to regulation under various federal and
state laws regarding, among other things, occupational safety, environmental
protection, hazardous substance control and product advertising and promotion.
In connection with its research and development activities, the Company is
subject to federal, state and local laws, and rules, governing the use,
generation, storage, discharge, handling and disposal of hazardous materials and
wastes. The Company believes that it has complied with these laws and rules in
all material respects, and it has not been required to take any action to
correct any material noncompliance. The Company does not currently anticipate
that any it will have to make any material capital expenditures in order to
comply with environmental laws or that compliance with such laws will have a
material effect on the financial condition or competitive position of the
Company. The Company may also be subject to foreign government regulations
regarding over-the-counter drug products. Accordingly, the Company intends to
submit applications to foreign regulatory agencies, if necessary, to make
therapeutic health claims for its products to be marketed abroad.

                                       14

Liability Insurance

         The Company's business involves exposure to potential product liability
risks that are inherent in manufacturing and marketing of pharmaceutical
products. The Company currently has general liability insurance with coverage
limits of $1,000,000 per occurrence and $2,000,000 as a general aggregate limit.
The coverage also includes product liability insurance subject to an aggregate
limit of $1,000,000. In addition, the Company has an umbrella policy providing
limits of $15,000,000 in excess of the general liability and the product
liability insurance. The Company's insurance policies provide coverage on a "per
occurrence" basis and a general aggregate basis, and are subject to annual
renewal. There can be no assurance that

o         the Company will be able to maintain such insurance on acceptable 
          terms

o         the Company will be able to secure increased coverage

o         or any insurance will provide adequate protection against potential 
          liabilities

Personnel

         The Company had as of March 1, 1999, 48 full-time employees and one
part-time employee. None of the Company's employees is represented by a union,
and the Company believes that its relationship with its employees is good.

ITEM  2.          DESCRIPTION OF PROPERTY

Properties

         The Company currently leases approximately 21,000 square feet of office
and laboratory space located at 7 Cedar Brook Drive, Cranbury, New Jersey for
approximately $36,400 per month. The lease began in September 1998 after the
Company's relocation from its previous facility in East Brunswick, New Jersey,
and expires in August 2008.

         The Company also leases office facilities located at 15 Kimball Avenue,
Yonkers, New York from an employee and one of his relatives for a total of
$3,100 per month.

         The Company leases an additional 5,000 square feet for its
manufacturing needs in East Brunswick, New Jersey for $3,950 per month, which
expires August 30, 2002.

         The Company believes that these properties are sufficient for its
administrative and research and development needs for the foreseeable future.
Since the Company presently intends to rely on outside manufacturers to
manufacture its products, it does not have a manufacturing facility.

ITEM  3.          LEGAL PROCEEDINGS

         The Company is not a party to any material pending legal or
administrative proceedings.

ITEM  4.          SUBMISSION OF MATTERS TO A VOTE OF SECURITY HOLDERS

         None.

Company's financial condition, results of operations and such other factors as
the Board of Directors deems relevant.

Recent Sales of Unregistered Securities

         In December 1998, the Company issued 1,959 shares of common stock and
granted warrants to purchase 392 shares of common stock exercisable at $6.125
per share from January 1, 2000 through December 31, 2004, to a corporation in
consideration for certain advertising run in its publication in December 1998.
The corporation represented that each of its stockholders was an accredited
investor. The Company relied on Section 4(2) and (6) of the Securities Act of
1933 and Rule 506 under Regulation D of the Securities Act for the exemption
from registration in connection with the issuance of those shares and warrants. 

         In December 1998, the Company issued 500 shares of its series B
convertible preferred stock to three accredited investors for a purchase price
of $10,000 per share. The series B convertible preferred stock is convertible at
a conversion price equal to the lower of the Variable Conversion Price of the
Company's common stock on the date of conversion or the Maximum Conversion Price
of the series B convertible preferred stock. The Variable Conversion Price is
equal to the average of the five lowest closing sale prices of the Company's
common stock on the Nasdaq National Market in the 40 trading days immediately
preceding the conversion. The Maximum Conversion Price is equal to 120% of the
average of the closing prices of the Company's common stock on the last five
trading days of February 1999. The Maximum Conversion Price is approximately
$7.19. The number of shares of the Company's common stock issuable on conversion
of each share of series B convertible preferred stock is equal to the sum of
$10,000 plus an accrual amount equal to 6% per annum divided by the conversion
price. The Company relied on Section 4(2) and 4(6) of the Securities Act and 
Rule 506 under Regulation D of the Securities Act for the exemption from 
registration in connection with the issuance of those shares.


ITEM  6.          MANAGEMENT'S DISCUSSION AND ANALYSIS OR PLAN OF OPERATIONS

         The following discussion and analysis should be read in conjunction
with the Financial Statements and Notes thereto included in Item 7 to this
report. Except for the historical information contained herein the foregoing
discussion contains forward-looking statements that involve risks and
uncertainties. The Company's actual results could differ materially from those
projected in the forward-looking statements discussed herein.

General

         The Company was founded in June 1992 to develop and market
over-the-counter oral care products that prevent tooth decay at its earliest
stage and are based on proprietary formulations and technologies. The Company
had not commenced any product commercialization or realized any operating
revenues as of December 31, 1996. In March 1997, the Company initiated marketing
activities for Enamelon(R) all-family toothpaste in selected United States
markets. The national distribution of Enamelon(R) all-family fluoride toothpaste
began in the first quarter of 1998, and the Company emerged from the development
stage at that time.



                                       17

<PAGE>



          The Company's strategic plan for accomplishing its objectives is to

o         continue marketing and expand distribution of Enamelon(R) toothpaste 
          products,

o         launch Enamelon(R) Calcium Whitening System toothpaste and other new 
          products,

o         continue marketing to dental professionals,

o         broaden product claims by conducting further product testing in 
          humans,

o         obtain the ADA Seal of Approval,

o         collaborate with corporate partners in certain other product areas and
          international markets, and

o         capitalize on additional commercial applications of both the Enamelon 
          Licensed and Proprietary Technologies.

          The Company expects to continue to incur operating losses through 
2000 and will require additional financing by mid-year 1999. Thereafter, or
sooner if conditions necessitate, the Company will need to raise additional
funds through public or private financings. The Company has retained an
investment banking firm to assist it in obtaining additional financing to meet
its future cash requirements. There can be no assurance that the Company will be
able to obtain additional financing to fund its operations. If adequate funds
are not available, then the Company may be required to reduce the scope of
proposed operations.

Results of Operations

     Year Ended December 31, 1998 Compared to Year Ended December 31, 1997

         Net sales for the year ended December 31, 1998 were approximately
$14,302,000 compared with $1,042,000 for the year ended December 31, 1997. The
increase in net sales is the result of the national distribution and growing
consumer acceptance of the Company's toothpaste as a result of coordinated
marketing efforts, including television and radio advertising, successful coupon
events as well as other promotional programs. While the Company will continue
its marketing efforts and anticipates further revenue growth as it adds new
product lines and markets, there can be no assurance that the increased sales
levels will be sustained.

         Gross profit earned in 1998 was $7,597,000 compared with a negative
gross margin of $426,000 in 1997. The improved gross profit was the result of
higher sales, increased production levels, and reduced raw material and
packaging costs due to increased volume. Negative gross margin in 1997 was a
result of costs associated with low production levels, high material costs,
manufacturing inefficiencies and product design changes during test marketing of
the Company's product. The Company anticipates the gross margin to improve as
production levels increase as a result of manufacturing efficiencies.

         Total operating expenses were approximately $38,308,000 for the year
ended December 31, 1998, compared with $10,906,000 in the prior year, an
increase of $27,402,000. This increase was primarily the result of higher
marketing and selling expenses of $25,546,000, research and testing expenses of
$372,000 and administrative and other expenses of $1,484,000. Additionally, the
Company

                                       18

<PAGE>

anticipates that total expenses will increase over the next few years as the
Company increases its product development, manufacturing and marketing
activities. Such increased business activities will require additional personnel
and payments to third parties.

         Marketing and selling expenses increased from $5,723,000 to
$31,269,000. This increase is primarily the result of increases in television,
print and media, and other promotion expenses in 1998 to launch the Company's
toothpaste product into national markets. The 1997 expenses reflected marketing
efforts in test markets that represented approximately 5% of all U.S.
households.

         Research and testing expenses increased from $2,844,000 to $3,216,000
primarily as a result of studies performed at universities and various
independent oral care research facilities in the United States to broaden
additional marketing claims for consumers and dentists and for personnel costs
associated with the Company's new product development. The Company intends to
continue expanding its clinical testing.

         Administrative and other expenses increased from $2,339,000 to
$3,823,000 primarily attributable to increased payroll and benefits, consulting,
and other administrative office expenses which resulted from the Company's
expanded operations.

         Interest and dividend income increased from $988,000 in 1997 to
$1,620,000 in 1998, primarily due to the increase in cash and cash equivalents
from a private placement and a second public offering of the Company's common
stock in 1997.

Liquidity and Capital Resources

         Since its inception in June 1992, the Company has financed its
operations primarily through private placements of Series A Preferred Stock, 
Common Stock and public offerings of Common Stock totaling approximately $56.9
million, net of expenses, and a private placement of Series B Convertible
Preferred Stock totaling $5,000,000. At December 31, 1998, the Company had cash
and cash equivalents and marketable securities of approximately $18.2 million
and working capital of $13.4 million. The Company had no outstanding debt (other
than accounts payable and accrued expenses) or available lines of credit as of
December 31, 1998.

         Since its inception and through December 31, 1998, the Company has
incurred losses aggregating approximately $44.6 million and had available net
operating loss carryforwards as of December 31, 1998 of approximately $44.3
million. The net operating loss carryforwards will expire if not used by the
period from 2007 through 2018 and may be limited by United States federal tax
law as a result of changes in ownership. The Company expects to continue to
incur operating losses at least through 2000 while it continues clinical testing
and toothpaste marketing efforts. The Company began a national roll-out of
Enamelon(R) toothpaste in 1998, which generated $14.3 million of net sales
during 1998. The Company believes that the national roll-out has been successful
and during the first quarter of 1999 will launch its Enamelon(R) Calcium
Whitening System toothpaste.

         The Company intends to use approximately $1.2 million of its cash
during 1999 to purchase additional manufacturing equipment for the production of
the Company's patented, dual-chamber toothpaste tube and for high-speed filling
equipment.

         In June 1997, the Company completed a private placement of 1,080,000
shares of common stock at $13.00 per share. Cash proceeds, net of costs, were
approximately $13,077,000.

                                       19

<PAGE>

         In October 1997, the Company sold 1,725,000 shares of Common Stock in a
secondary public offering at $16.50 per share, which resulted in cash proceeds,
net costs, of approximately $26,295,000.

         In December 1998, the Company completed a private placement of 500
shares of Series B Convertible Preferred Stock, $.01 par value, to three
purchasers for an aggregate purchase price of $5,000,000. Each share has a
stated value of $10,000, and each stockholder is entitled to a 6% return per
annum, payable on conversion in cash or the Company's Common Stock at the
Company's option. After February 28, 1999, holders of the Series B Convertible
Preferred Stock can convert it into Common Stock at the lower of (I) the average
of the five lowest closing sales prices in the 40 trading days immediately
preceding the conversion or (ii) 120% of the average of the closing prices of
the last five trading days of February 1999. The Company can require holders of
the Series B Convertible Preferred Stock to convert it into Common Stock at any
time between March 1, 1999 and August 28, 1999 if the closing price of the
Company's Common Stock exceeds 200% of the maximum conversion price for 20
consecutive trading days. After August 28,1999, the Company can require holders
of the Series B Convertible Preferred Stock to convert to Common Stock if the
closing price of the Company's Common Stock exceeds 150% of the maximum
conversion price for 20 consecutive days. Holders of the Series B Convertible
Preferred Stock will be required to convert their shares on December 17, 2001,
if they have not converted prior to that time.

         The Company's cash requirements may vary materially from those now
planned depending on numerous factors, including the status of the Company's
marketing efforts, the Company's business development activities, the
availability of alternative financing for the acquisition of manufacturing
equipment, the results of clinical trials, the regulatory process and
competition. Under the Company's current plan, management estimates that cash
and cash equivalents on hand, together with its projected cash flow from
operations, if any, will be sufficient to finance its working capital and other
requirements through mid-1999. Thereafter, or sooner if conditions necessitate,
the Company will need to raise additional funds through public or private
financings. The Company has retained an investment banking firm to assist it in
obtaining additional financing to meet its future cash requirements. Should such
additional financing not be obtained, management believes that the Company can
obtain additional financing through other sources to continue its operations.
There can be no assurance that the Company will be able to obtain additional
financing to fund its operations. If adequate funds are not available, then the
Company may be required to reduce the scope of proposed operations.

Forward-Looking Statements

         This Management's Discussion and Analysis or Plan of Operations and
other sections of this report contain forward-looking statements that are based
on current expectations, estimates, forecasts and projections about the industry
in which the Company operates, management's beliefs and assumptions made by
management. These statements are not guarantees of future performance and
involve certain risks, uncertainties and assumptions which are difficult to
predict. Therefore, actual outcomes and results may differ materially from what
is expressed or forecasted in such forward-looking statements. The Company
undertakes no obligation to update publicly any forward-looking statements,
whether as a result of new information, future events or otherwise.

Readiness for Year 2000

         The information provided below constitutes a "Year 2000 Readiness
Disclosure" for purposes of the Year 2000 Information and Readiness Disclosure
Act.

         The Year 2000 ("Y2K" ) issue refers to possible events resulting
directly or indirectly from the inability of digital computer equipment or
software to accurately and without interruption handle dates both before and
after January 1, 2000 and to process the year 2000 as a leap year.

                                       20

<PAGE>

         The Company has reviewed its manufacturing and resource planning
software and current operating system and believes that they are Y2K compliant.
The Company primarily utilizes operating systems obtained from Microsoft, which
the Company believes, based on information provided by Microsoft, are Y2K
compliant. The Company believes that none of the Company's equipment is date
sensitive or otherwise uses imbedded computer chips. Accordingly, the Company
does not believe that embedded chip technology will present any Y2K issues.
However, the Company is also checking its equipment to verify this as part of
its overall Y2K program. The Company expects that the costs of achieving
internal Y2K compliance will not have a material adverse impact on results of
operations, liquidity or capital resources.

         The Company is in the process of formally contacting its suppliers to
identify any potential disruption in the supply of raw materials. The Company
expects to resolve any significant Y2K issues before the occurrence of any
business disruptions, although the Company has limited or no control over the
actions of the suppliers. However, the Company believes that the supply of
chemicals and raw materials used in its manufacturing processes is unlikely to
be significantly disrupted. In addition, the Company, in the normal course of
business, maintains adequate inventories of such raw materials to protect
against short-term delivery interruptions.

         The risk to the Company resulting from the failure of customers and
other third parties to attain Y2K readiness is the same as other companies in
its industry or other business enterprises generally. The Company expects to
resolve any significant Y2K issues with customers before the occurrence of any
business disruptions, although the Company has limited or no control over the
actions of these customers. The Company expects to maintain adequate finished
goods inventories to protect customers against the possibility of temporary
service disruptions, if any.

         The Company expects to find and adequately prepare for all significant
internal Y2K issues that could adversely affect its business operations. The
Company does not anticipate that the cost of resolving such issues will have a
material impact on its financial position, results of operations or liquidity.
While the Company believes its efforts are adequate to address the Y2K concerns,
there can be no guarantee that all internal systems, as well as those of third
parties on which the Company relies will be converted on a timely basis and will
not have a material adverse affect on the Company's operations. However, the
Company does not believe that it is possible to identify, with complete
certainty, all potential Y2K issues that may affect the Company, its suppliers,
or its customers. The Company expects that any disputes arising as a result of
such identified Y2K issues will be resolved in the normal course of business.

     Recently issued accounting standards may affect the Company's Financial
Statements in the future. See the section "Financial Statements" in Item 7 of
this report.

Report of Independent Certified Public Accountants

Enamelon, Inc.
Yonkers, New York

         We have audited the accompanying balance sheets of Enamelon, Inc. as
of December 31, 1998 and 1997, and the related statements of operations,
stockholders' equity, and cash flows for the years then ended. These financial
statements are the responsibility of the Company's management. Our
responsibility is to express an opinion on these financial statements based on
our audits.

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

         In our opinion, the financial statements referred to above present
fairly, in all material respects, the financial position of Enamelon, Inc., as
of December 31, 1998 and 1997, and the results of its operations and its cash
flows for the years then ended in conformity with generally accepted
accounting principles.

                         Notes to Financial Statements

1.    Organization and Summary of Accounting Policies

       Organization

         Enamelon, Inc. (the "Company") develops and markets over-the-counter
oral care products that help stop cavities before they begin. The Company's
products are based on proprietary formulations and technologies that have been
shown in laboratory and human studies to enhance remineralization of tooth
enamel and to prevent early stage tooth decay. The Company's toothpastes
contain the active ingredient sodium fluoride in a formulation with calcium
and phosphate ions, to enhance the remineralization of tooth enamel. The
Company launched its initial product, Enamelon(R) all-family toothpaste, in
test markets in March 1997 and began the product's national introduction in
the first quarter of 1998. The Company emerged from the development stage upon
launch of its initial product. The Company expects to launch Enamelon(R) Calcium
Whitening System toothpaste, its second product, nationally in the second
quarter of 1999. The Company expects to continue to incur operating losses
through 2000 and will require additional financing by mid-year 1999, to continue
its operations until that time and possibly thereafter. The Company has 
retained an investment banking firm to assist it in obtaining additional
financing to meet its future cash requirements.

     Use of Estimates

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

     Fair Value of Financial Instruments

         The carrying amounts of cash, accounts receivable, accounts payable
and accrued expenses approximate fair value because of the short maturity of
these items.

     Cash and Cash Equivalents

         Cash and cash equivalents consist of highly liquid debt instruments
with original maturities of three months or less, principally commercial paper
and money market accounts.

     Investments

         Investments consist of certificates of deposit and corporate and
government bonds that mature in more than 91 days, but not more than one year,
or securities with maturities beyond one year that management intends to sell
within one year. The investments are classified as trading securities and are
recorded at fair market value with the related gain or loss, which was not
material, reflected in the Company's statement of operations. Fair market
value is determined based upon quoted market values as reported by a national
securities exchange.

     Inventory

         Inventory is stated at the lower of cost, determined by the first-in,
first-out (FIFO) method, or market.

     Equipment

         Equipment is stated at cost. Depreciation is computed over the
estimated useful lives of the assets using the straight-line method.

                                      F-7

                   Notes to Financial Statements - Continued

     Intangible Assets

         Organization costs are amortized using the straight-line method over
a sixty-month period. Licensing costs and patent rights are amortized using
the straight-line method over seventeen years, which is the term of the
licensing agreements and the estimated useful lives of the patents,
respectively. Trademarks are being amortized using the straight-line method
over seventeen years.

     Revenue Recognition

         Revenue from product sales is generally recognized at the time the
product is shipped to the customer. Upon shipment, the Company also provides
for the estimated cost that may be incurred for returned product.

     Reclassification of prior year amounts

     Net revenues from 1997 test market sales of $1,041,838 and the costs
associated with such sales of $1,468,080 were previously netted and presented
as a component of marketing and selling expenses. These amounts have been
reclassified to revenues and cost of sales, respectively, in the accompanying
statement of operations.

     Advertising Expenses

         Advertising costs are expensed as of the first date the advertisement
takes place. Expenses, which consist primarily of television, print and media,
and other promotional costs, were $13,256,016 in 1998 and $4,427,665 in 1997.

     Research and Development

         Costs for research and development are expensed as incurred.

     Income Taxes

         Income taxes are computed in accordance with the provisions of
Statement of Financial Accounting Standards No. 109, "Accounting for Income
Taxes" ("SFAS 109"), which requires, among other things, a liability approach
to calculating deferred income taxes. SFAS 109 requires a company to recognize
deferred tax liabilities and assets for the expected future tax consequences
of temporary differences between the carrying amount of assets and liabilities
for financial reporting purposes and the amounts used for income tax purposes.
Deferred tax assets must be reduced by a valuation allowance to amounts
expected to be realized.

     Earnings Per Share

         Effective December 15, 1997, the Company adopted Statement of
Financial Accounting Standards No. 128, "Earnings Per Share", which provides
for the calculation of "Basic" and "Diluted" earnings (loss) per share. In
accordance with this statement, basic loss per share for the years ended
December 31, 1998 and 1997 was calculated by dividing net loss by the weighted
average number of common shares outstanding, which amounted to 10,165,362 and
7,875,504, respectively. Diluted loss per share for the years ended December
31, 1998 and 1997 was calculated by dividing net loss by the weighted average
number of common shares and all dilutive potential common shares (comprising
outstanding options and warrants) which amounted to 10,853,796 and 9,283,959,
respectively. Diluted loss per share has not been presented since the effect
of dilutive common shares is antidilutive in all periods.

     Recent Accounting Standards

         In June 1998, the FASB issued SFAS No. 133, "Accounting for
Derivative Instruments and Hedging Activities." This statement is effective in
the year 2000 but is not expected to affect the Company.

         Stock Option Plans

         The Company has two stock Option Plans, adopted in 1993 and 1997 (the
"Option Plans"). The Option Plans provide for the grant of options to
qualified employees (including officers and directors) of the Company to
purchase an aggregate of 2,250,000 shares of common stock. The Option Plans
are administered by the Board of Directors or a committee of the Board of
Directors (the "Compensation Committee") whose members are not entitled to
receive options under the Option Plans (excluding options granted exclusively
for directors' fees). Options granted under the Plans may or may not be
"incentive stock options" as defined in the Internal Revenue Code ("Incentive
Options") depending upon the terms established by the Compensation Committee
at the time of grant. The exercise price shall not be less than the fair
market value of the Company's common stock as of the date of grant (110% of
the fair market value if the grant is an Incentive Option to an employee who
owns more than 10% of the Company's outstanding common stock). Options granted
under the Plans are subject to a maximum term of 10 years, 5 years for an
employee who also owns more than 10% of the Company's outstanding common stock.

         SFAS No. 123, Accounting for Stock-Based Compensation, requires the
Company to provide pro forma information regarding net income(loss) and
earnings(loss) per share as if compensation cost for the Company's stock
option plans had been determined in accordance with the fair value based
method prescribed in SFAS No. 123. The Company estimates the fair value of
each stock option at the grant date by using the Black-Scholes option-pricing
model with the following weighted-average assumptions used for grants during
the years ended December 31, 1997 and 1998, respectively; no dividend yield
for either period; expected volatility of 37 and 35 percent; risk-free
interest rates of 5.9 and 5.3 percent, and expected lives of 6.9 and 7.3
years for the options.

         Under the accounting provisions of SFAS No. 123, the Company's net
loss and loss per share would have been increased to the pro forma amounts
indicated below:

8.    Income Taxes

         At December 31, 1998, the Company had a deferred tax asset of
approximately $17,760,000 primarily attributable to net operating loss
carryforwards. The deferred tax asset has been fully reserved by a valuation
allowance of the same amount.

         The net operating loss carryforwards at December 31, 1998 totaling
approximately $44,400,000 will expire if not used by the period from 2007
through 2018 and may be limited by United States federal tax law as a result
of changes in ownership.

     Leases

         The Company leases office facilities in New York from a related
party. During 1998, the Company entered into a ten-year lease agreement for
office and laboratory facilities in Cranbury, New Jersey and relocated to
these facilities in September 1998. The Company also leases equipment and
automobiles at locations in New York and New Jersey.

         The following is a schedule of future minimum lease payments for
operating leases that had initial or remaining non-cancelable lease terms in
excess of one year as of December 31, 1998:

         Rent expense for the years ended December 31, 1997 and 1998 was
$129,089 and $380,831, respectively.

     Patent License Agreements

         In April 1998, the Company entered into an amendment to its license
agreement with the American Dental Association Health Foundation ("the ADAHF")
which was originally signed in June 1992 and which was subsequently restated
and amended and further amended in June 1995 (as amended, the "License
Agreement"). The License Agreement grants the Company a fully-paid exclusive
United States license to manufacture and sell toothpastes and chewing gum and
other food and confectionery products ("Exclusive Products") using the ADAHF
Patented Technology. Under the License Agreement, beginning in 1998 the
Company is required to pay a fixed annual royalty of $400,000 through 2008
with respect to all Company sales of Exclusive Products (whether or not they
rely upon the ADAHF Patented Technology) up to $100 million in that year and
an additional fixed royalty of $200,000 with respect to all Company sales of
Exclusive Products exceeding $100 million in that year. The Company has made
the required payments under this agreement. The Company has the right to
sublicense or assign all or any part of its rights under the License
Agreement, but will continue to be liable for payment of the fixed royalties
regardless of such sublicense or assignment. The term of the License Agreement
expires upon the last to expire of the ADAHF Patent Rights, including any
continuations, divisions, reexaminations, extensions or releases thereof.

         In April 1998, the Company entered into an amendment to its foreign
license agreement with the ADAHF, which was originally signed in November 1992
and subsequently restated and amended and further amended in June 1995 (as
amended, the "Foreign License Agreement"). The Foreign License Agreement
grants the Company an exclusive license to manufacture and sell Exclusive
Products using technology that is the subject matter of foreign patent
applications filed by the ADAHF in certain foreign countries. In addition, the
Foreign License Agreement grants the Company the non-exclusive right to
manufacture and sell other products in such countries using the technology
that is the subject of such foreign patent applications, including oral
sprays, mouth rinses and professional gels (collectively, "Non-Exclusive
Products"). The Company's payment of royalties under the License Agreement
will constitute a fully-paid license under the Foreign License Agreement with
respect to the Exclusive Products. Under the Foreign License Agreement, the
Company is required to pay 7% of net sales of Non-Exclusive products (4% if
such sales are made by an entity that enters into a joint venture with the
Company and bears the costs of prosecution of foreign patent applications).
Since the Company has no current foreign sales, no payments have required
under this agreement.

10.  Employment Agreements

         The Company currently has employment agreements with five officers.
Such agreements vary in length from one to five years and expire at various
dates through 2003. Annual salaries (subject to adjustment) committed under
the terms of existing employment contracts total $733,000, $701,500, $580,000,
$465,850 and $512,425 in the years ended December 31, 1999, 2000, 2001, 2002,
and 2003, respectively. In addition, the four officers receive options under
the Company's stock option plans and share in an annual bonus pool, equal to
5% of the Company's net income before expenses (as defined), established under
the terms of the Company's Incentive Compensation Program.

         Under the terms of the employment agreement with the Company's
Chairman and Chief Executive Officer (the "CEO"), if the CEO opposes a change
in control of the Company (as defined) and thereafter elects to terminate his
employment with the Company, he is entitled to receive 2.9 times the sum of
his current base annual salary ($350,000 as of January 1, 1999) plus any
amounts due him under the Company's Incentive Compensation Plan. The CEO is
entitled to 50% of the amounts allocated to the Company's Incentive
Compensation Plan.

Directors each year during the term hereof to such plan for the purpose of
providing an incentive to key employees. In addition, in the event the term
hereof is not commensurate with the fiscal year of the Company or the Executive

hereunder pursuant to the terms of an executive compensation plan shall be
pro-rated for any such fiscal year during which the Executive was not employed
for the full twelve-month period thereof.

                  (d) The Company will use its best efforts to procure the
following insurance policies designating the Executive as the insured: (i) a
disability policy providing for disability income to the Executive of $15,000
per month and (ii) a term life insurance policy in the face amount of
$2,000,000, provided that (i) the premiums for said policies do not aggregate in
excess of $27,000 per year. If the premiums exceed such maximum amount, the
Company may procure less insurance for Executive in such combination as the
Executive shall specify. In addition, the Executive shall have the right to
allocate such maximum amount of premiums between disability insurance and life
insurance in such combinations as he may specify in his sole discretion. The
beneficiaries of such policies shall be designated by the Executive. In the
event the Company is

                                       -2-

<PAGE>



unable to procure such policy, nothing hereunder shall obligate the Company to
remit any payments which would have been used to pay the premiums for such
policy to Executive.

                  (e) The Executive's salary shall be payable subject to such
deductions as are then required by law and such further deductions as may be
agreed to by the Executive, in accordance with the Company's prevailing salary
payroll practices.

         5.       Benefits and Expenses
                  ---------------------

                  (a) The Executive shall participate in all fringe benefits
such as medical, dental, disability, hospital and health insurance plans, profit
sharing, pension and stock option plans, life insurance and other plans, if any,
which the Company may generally make available to its executive employees.

                  (b) In the event that the Executive's employment by the
Company is terminated for any reason, the Executive shall have the right to
purchase from the Company any insurance policies on his life owned by the
Company for a price equal to the cash surrender value of the policies at the
date of such termination, plus prepaid premiums. The right to purchase shall be
exercised by the Executive by written notice to the Company not less than seven
(7) days prior to the date of such termination, and the purchase price for such
policies shall be paid by the Executive to the Company on the date of
termination.

                  (c) During the term of this Agreement, the Company shall, upon
presentation of proper vouchers, reimburse the Executive for all reasonable
expenses incurred by him directly in connection with his performance of services
as an officer and employee of the Company.

                  (d) The Executive shall be entitled to such vacation as
permitted in accordance with any policy established by the Board of Directors
from time to time, but in no event shall Executive be entitled to less than six
(6) weeks vacation per year.

                  (e) The Executive shall receive as paid days off all national
holidays that the Company, pursuant to established policy, recognizes and
observes.

         6.       Disability and Death
                  --------------------

                  (a) In the event of the permanent disability of Executive, as
hereinafter defined, the Company shall have the right thereafter to terminate
this Agreement with Executive by sending written notice of such termination to
Executive, and thereupon this Agreement shall terminate. For purposes hereof,
"permanent disability" shall mean the inability of Executive to perform his
duties hereunder due to physical or mental illness, including drug abuse and
alcoholism, for six (6) months in any twelve (12) consecutive month period. In
addition, the "permanent disability" of Executive shall also have been deemed to
have occurred if the Executive shall have had appointed a guardian or
conservator for him or such appointment shall have been made by a court of
competent jurisdiction.

                                       -3-

<PAGE>



                  (b) The parties hereto hereby agree that if a disagreement
arises as to whether a condition of disability exists hereunder, Executive shall
submit to a physical examination by a physician of his own choice and by a
physician of the Company's choice. If either physician so chosen does not agree
as to the determination of disability, the two physicians shall mutually select
a third qualified physician, whose determination shall be conclusive upon all
parties. Each party shall bear the expense of the physician selected by such
party and the expense of the third physician shall be borne equally by Executive
and the Company. Executive hereby consents to the examination provided for
herein and waives, if applicable, any privilege which exists between any
physician and Executive as a result of such examination.

                  (c) This Agreement shall also terminate upon and as of the
date of death of the Executive at any time during the term of this Agreement.

                  (d) Notwithstanding anything contained herein to the contrary,
Executive shall be compensated as set forth in this Agreement through the date
of termination of this Agreement due to permanent disability or death, provided,
however, in the event of permanent disability any such compensation shall be
reduced by any amounts payable to Executive from or in respect of disability
insurance plans for which the Company has paid any portion of the premiums
therefore and which payments are received by the Executive for the period of
such incapacity or illness. If the Executive dies during the term of this
Agreement, not later than 90 days after the date of death, the Company shall pay
the Executive's estate or other designated beneficiary an amount equal to two
times the Executive's annual salary on the date of death.

         7.       Covenants and Restrictions
                  --------------------------

                  The Executive covenants that, except in carrying out his 
duties hereunder, during the term of his employment and for a period of eighteen
(18) months following the date of termination of employment hereunder,
irrespective of the reasons for any such termination and unless such longer
period of time is specifically set forth herein:

                  (a) Executive will not, directly or indirectly, own any
interest in, participate or engage in, assist, render any services (including
advisory services) to, become associated with, work for, serve (in any capacity
whatsoever, including, without limitation, as an employee, consultant, advisor,
agent, independent contractor, officer or director) or otherwise become in any
way or manner connected with the ownership, management, operation, or control
of, any business, firm, corporation, partnership or other entity (collectively
referred to herein as a "Person") that engages in, or assists others in engaging
in or conducting any business, which deals, directly or indirectly, in products
or services competitive with the Company's product line or services, as
described below, anywhere in the world; and provided, however, the above shall
not be deemed to exclude Executive from acting as a director of a corporation
for the benefit of the Company with the consent of the Company's Board of
Directors; and provided further, however, that the above shall not also be
deemed to prohibit Executive from owning or acquiring securities issued by any
corporation which neither directly nor indirectly competes with the Company. For
purposes hereof, "products or services competitive with the Company's product
line or services" shall mean any products or

                                       -4-

<PAGE>



services that compete directly with the Company's products or services in the
same category at the time of the termination of the Executive's employment with
the Company.

                  (b) Executive shall not sell or solicit any products or
services to any customer of the Company, except on behalf of the Company. The
term "customer" shall mean any Person or individual (including any Person or
individual who controls, is under common control with or has the ability to
control any such Person) to whom the Company has provided goods or services
within the twenty-four (24) month period prior to the termination of Executive's
employment hereunder or to whom the Executive had actively solicited business in
an attempt to develop such Person or individual as a customer of the Company
during the term hereof, or any licensee of the Company who was a licensee of the
Company at any time during the twenty-four (24) month period prior to the
termination of this Agreement.

                  (c) The Executive hereby covenants and agrees that the
Executive will not at any time subsequent to the date hereof, reveal, divulge,
or make known to any person, firm or corporation, any Confidential Information,
as defined hereinafter, made known to Executive or of which Executive has become
aware, regardless of whether developed, prepared, devised or otherwise created
in whole or in part by the efforts of the Executive and except to the extent so
authorized in writing by the Company in order to carry out the terms of this
Agreement or except as required by law. For purposes of this Agreement, the term
"Confidential Information" shall mean any technical, scientific or engineering
information relating to the Company's products and/or services; information
relating to any customer of the Company, including without limitation, the
names, addresses, telephone numbers and sales records of, or pertaining to any
such customer; price lists, methods of operation and other information
pertaining to the Company and which the Company, in its sole discretion, regards
as confidential and in the nature of trade secrets. Notwithstanding anything
contained herein to the contrary, Confidential Information as used herein shall
not include that which (i) was in the public domain prior to receipt hereunder
in the same context as the disclosure made hereunder; or (ii) Executive can show
was in his possession and in the same context prior to receipt; or (iii)
subsequently becomes known to Executive by third parties not in the course of
this Agreement and as a matter of right and without restriction on disclosure;
or (iv) subsequently comes into the public domain in the same context as the
disclosure by the Company through no fault of Executive.

                  (d) The Executive further covenants and agrees that Executive
shall retain all of such Confidential Information in trust for the sole benefit
of the Company, and shall not divulge or deliver or show any of such
Confidential Information to any unauthorized person and shall not make use of or
in any manner seek to turn to account any of such Confidential Information in an
independent business however unrelated to the business of the Company. The
Executive further agrees that upon the termination of this Agreement or upon the
request of the Company, the Executive will either supply or return to the
Company, in accordance with the Company's request, all Confidential Information
in the Executive's possession, including, without limitation, all account lists,
records and data related to all customers of the Company.


                                       -5-

<PAGE>



                  (e) Executive will neither solicit, hire or seek to solicit or
hire any of the Company's personnel, irrespective of the capacity of such
personnel, including any agent, independent contractor, or consultant to the
Company, nor shall Executive induce or attempt to induce any of the Company's
personnel to leave the employ of the Company to work for Executive or otherwise,
or to terminate their relationship with the Company.

                  (f) Executive acknowledges that his breach or threatened
violation of any of the restrictive covenants contained in this Section 7 may
cause irreparable damage to the Company for which remedies at law would be
inadequate. Executive further acknowledges that the restrictive covenants set
forth herein are essential terms and conditions of this Agreement. The Executive
therefore agrees that the Company shall be entitled to a decree or order by any
court of competent jurisdiction enjoining such threatened or actual violation of
any of such covenants. Such decree or order, to the extent appropriate, shall
specifically enforce the full performance of any such covenant by the Executive
and the Executive hereby consents to the jurisdiction of any such court of
competent jurisdiction and authorizes the entry on its behalf of any required
appearance for such purpose. This remedy shall be in addition to all other
remedies available to the Company at law or equity. If any portion of this
Section 7 is adjudicated to be invalid or unenforceable, this Section 7 shall be
deemed amended to delete therefrom the portion so adjudicated, such deletion to
apply only with respect to the operation of this Section 7 in the jurisdiction
in which such adjudication is made.

         8.       Proprietary Property
                  --------------------

                  (a) The parties hereto hereby agree that Proprietary Property,
as hereinafter defined, shall be the sole and exclusive property of the Company,
except as provided below. For purposes hereof, Proprietary Property shall mean
inventions, discoveries, improvements, ideas, trade secrets and know how,
whether patentable or not, made solely by Executive or jointly with others,
which relate to the Company's business, including any of its products, services,
processes, technology, research, product development, marketing programs,
manufacturing operations, or engineering activities.

                  (b) Executive shall promptly disclose to the Company in
writing all Proprietary Property, including those in the formative stages,
created during the term hereof, irrespective of whether created during normal
business hours. In addition, Executive hereby agrees to promptly disclose to the
Company all Proprietary Property created subsequent to the date of termination
hereof, irrespective of the reasons for termination hereof, which relate to or
constitute an improvement on Proprietary Property or Confidential Information,
as defined herein.

                  (c) Executive hereby agrees and acknowledges that Executive
shall have no right, title or interest in or with respect to any Proprietary
Property, except as described below, and will during the term hereof or at any
time subsequent to the termination hereof, at the Company's request and expense,
execute any and all patent applications and assignments to the Company and take
any all action as required by the Company to perfect and maintain the Company's
rights and interests in and with respect to the Proprietary Property.


                                       -6-

<PAGE>



                  (d) Executive hereby agrees to maintain written records
concerning the Proprietary Property and agrees to make those records available
to the Company at all times.

                  (e) Notwithstanding anything contained herein to the contrary,
Proprietary Property shall not include inventions or discoveries with respect to
which all of the following conditions apply:

                           (i)     no equipment, supplies, facilities or 
Confidential Information of the Company was used in its development;

                           (ii)    it was developed on the Executive's own time;

                           (iii)   it does not relate to the Company's business
and/or any proposed or planned products or services of the Company, including
any research and development activities; and

                           (iv)    it does not arise in connection with any work
 performed by the Executive for the Company.

                  (f) During or subsequent to the Executive's employment by
Company, Executive will not, directly or indirectly, lecture upon, publish
articles concerning, use, disseminate, disclose, sell or offer for sale any
Proprietary Property without the Company's prior written permission.

         9.       Prior Agreements
                  ----------------

                  Executive represents that he is not now under any written
agreement, nor has he previously, at any time, entered into any written
agreement with any person, firm or corporation, which would or could in any
manner preclude or prevent him entering into this Agreement and abiding by the
terms and conditions hereof.

         10.      Termination Provisions
                  ----------------------
                    
                  (a) In addition to, and not in lieu of, the termination
provisions set forth in Section 6 of this Agreement, the employment of the
Executive hereunder may be terminated by the Company prior to the termination
date of the initial term or any renewal term thereafter (as set forth in Section
2 hereof) in the event that the Executive (i) breaches this Agreement or (ii)
engages in any act of dishonesty with respect to the Company, including any act
of willful misfeasance (the foregoing reasons for termination set forth under
Subparagraphs (i) and (ii) above are sometimes referred to hereinafter as
termination for "Cause"). Such termination of the Executive's employment
hereunder shall be effective immediately upon delivery of written notice to the
Executive setting forth the reason or reasons for such termination. Upon the
termination of this Agreement in accordance with this Section 10(a), the Company
shall not be obligated to make any further payments hereunder to the Executive.


                                       -7-

<PAGE>



                  (b) If, as both a director and a stockholder of the Company,
Executive opposes a "change of control" (defined below) of the Company and such
change of control shall occur at any time during Executive's employment
hereunder in spite of Executive's objection, Executive may by at least thirty
(30) days prior written notice to the Company given within six (6) months of
such change of control, elect to terminate his employment with the Company at
the end of such six (6) month period. If Executive elects to terminate his
employment pursuant to this Section 10(b), the Company shall promptly pay him
two and nine-tenths (2.9) times his current compensation payable under Sections
4(a) and 4(b) within thirty (30) days of receipt of Executive's notice;
provided, however, in no event shall the amount paid to Executive pursuant to
this Paragraph 10(b) exceed the maximum payment permitted by Section 280G of the
Internal Revenue Code of 1986, as amended (the "Code") or then applicable law
and to the extent any "excess parachute payment", as that phrase is defined in
Section 280G(b) of the Code or then applicable law, would result from the
application of the formulas set forth in (i) or (ii) above, then the amount
Executive would otherwise receive shall be reduced so that no "excess parachute
payment" is made by the Company or received by Executive; provided further,
however, that this Section 10 shall not apply to any change in control supported
by the Executive either as an officer, a director or as a stockholder of the
Company. A "change of control" shall be deemed to occur when any person,
corporation, partnership, association or entity, directly or indirectly (through
a subsidiary or otherwise), (A) acquires or is granted the right to acquire,
directly or through a merger or similar transaction, a majority of Company's
outstanding voting securities, or (B) acquires all or substantially all of the
Company's assets.

         11.      Miscellaneous
                  -------------

                  (a) This Agreement shall inure to the benefit of and be
binding upon the Company, its successors and assigns, and upon the Executive,
his heirs, executors, administrators, legatees and legal representatives.

                  (b) Should any part of this Agreement, for any reason
whatsoever, be declared invalid, illegal, or incapable of being enforced in
whole or in part, such decision shall not affect the validity of any remaining
portion, which remaining portion shall remain in full force and effect as if
this Agreement had been executed with the invalid portion thereof eliminated,
and it is hereby declared the intention of the parties hereto that they would
have executed the remaining portion of this Agreement without including therein
any portion which may for any reason be declared invalid.

                  (c) This Agreement shall be construed and enforced in
accordance with the laws of the State of New York applicable to agreements made
and to be performed in such State without application of the principles of
conflicts of laws of such State.

                  (d) This Agreement and all rights and obligations hereunder
are personal to the Executive and shall not be assignable or delegable, and any
purported assignment or delegation in violation hereof shall be null and void.
Any person, firm or corporation succeeding to the business of the Company by
merger, consolidation, purchase of assets or otherwise, shall assume by contract
or operation of law the obligations of the Company hereunder; provided, however,
that the Company shall, notwithstanding such assumption and/or assignment,
remain liable and responsible for the fulfillment of the terms and conditions of
the Agreement on the part of the Company.

<PAGE>


                  (e) This Agreement constitutes the entire agreement between
the parties hereto with respect to the terms and conditions of the Executive's
employment by the Company, and this Agreement supersedes and renders null and
void any and all other prior oral or written agreements, understandings, or
commitments pertaining to the Executive's employment by the Company. This
Agreement may only be amended upon the written consent of both parties hereto.

                  (f) Any notice required or permitted to be given under this
Agreement shall be in writing and shall be delivered in person, by nationally
recognized courier service or by certified mail, return receipt requested,
postage prepaid, to the parties at the addresses set forth above, or at such
other place that either party may designate by notice in the foregoing manner to
the other. If mailed as aforesaid, any such notice shall be deemed given on
receipt or three (3) days after being so mailed, unless the receiving party
proves the notice was received later or not received.

                  (g) The failure of either party to insist upon the strict
performance of any of the terms, conditions and provisions of this Agreement
shall not be construed as a waiver or relinquishment of future compliance
therewith, and said terms, conditions and provisions shall remain in full force
and effect. No waiver of any term or any condition of this Agreement on the part
of either party shall be effective for any purpose whatsoever unless such waiver
is in writing and signed by such party.

                  (h) The provisions of Sections 6, 7, 8, 10 and 11 of this
Agreement shall survive any termination of this Agreement.

                  (i) The headings in this Agreement are inserted for
convenience and shall not affect any interpretation of this Agreement.

               IN WITNESS WHEREOF, the parties hereto have executed this
Agreement as of the day and year first written above.

                              EMPLOYMENT AGREEMENT
                              --------------------

         EMPLOYMENT AGREEMENT, dated February 18, 1999 by and between
ENAMELON, INC., a Delaware corporation, having a principal place of business at
15 Kimball Avenue, Yonkers, New York 10704 (the "Company"), and KIM HARDINGHAM,
having a residence address at 3 Chaucer Ct., Princeton Junction, New Jersey
08550 (the "Executive").

                                    RECITALS
                                    --------

         The Executive is experienced in the field of developing, manufacturing,
marketing, and selling dentifrice and other oral care products. The Company
desires to employ the Executive to act as President of the Company and to render
services in that field, and the Executive desires to render such services on
behalf of the Company. Accordingly, the Company and the Executive desire to set
forth the terms and conditions on which (i) the Company will employ the
Executive, (ii) the Executive will render services to the Company and to any
other corporation or business entity controlled by the Company (each, a
"Subsidiary"), and (iii) the Company will compensate the Executive for such
services.

         NOW, THEREFORE, in consideration of the mutual covenants and agreements
herein set forth, and for other good and valuable consideration, the receipt and
sufficiency of which are hereby acknowledged, the parties hereto hereby agree as
follows:

         1.                Employment.
                           ----------

                           The Company hereby employs the Executive, and the 
Executive hereby accepts such employment, upon the terms and conditions herein
set forth.

         2.                Term.
                           ----

                           The term of this Agreement shall commence on the date
hereof and shall continue until terminated by the Company or the Employee in
their sole discretion, subject to the termination provisions of Sections 7, 8
and 9 and the other provisions of this Agreement.

         3.                Duties and Responsibilities.
                           ---------------------------

         3.1 During the Term of this Agreement, the Executive shall serve the
Company in an executive capacity and shall perform such duties as are determined
from time to time by the Company's Board of Directors. The Executive shall
devote his full attention and apply his best efforts, energies and skills on a
full-time basis, to the business of the Company and each Subsidiary (such
corporations or other business entities being referred to herein collectively as
the "Enamelon Group") and shall not during the Term of this Agreement be engaged
in any


<PAGE>

other business activity, whether or not such business activity is pursued for
gain, profit, or other pecuniary advantage. Subject to the provisions of Section
10 hereof, the foregoing restriction shall not be construed as preventing the
Executive from investing his assets in such form or manner as will not require
any services on his part in the operation of the affairs of the companies in
which such investments are made. In addition, the Company acknowledges that the
Executive and members of his family are the sole equity owners of Princeton
Dental Products, LLC ("PDP"). Anything in this Section 3 or in Section 10 to the
contrary notwithstanding, for so long as PDP is not a Competing Business (as
defined in Subsection 10.1.1), the Executive shall have the right during the
Employment Period and the Post- Termination Period (as such terms are defined in
Subsection 10.2) to continue to own an equity interest in PDP and to consult
with or give advice to PDP, provided that such consultation or advisory services
are not rendered during the Company's normal business hours and otherwise do not
interfere with the Executive's performance of his duties hereunder.

         3.2 During the Term, the Executive shall serve as and perform the
functions of President and Chief Operating Officer of the Company and shall
perform such other duties and functions as the Board of Directors, the Chairman
of the Board, or the Chief Executive Officer of the Company may determine,
consistent with the Executive's experience and background. The Executive will be
one of the Company's principal operating officers and will conduct and manage
the Company's business in accordance with the policies established by the
Company from time to time. The Executive shall be principally responsible for
performing such services at the Company's offices at 7 Cedar Brook Road,
Cranbury, New Jersey.

         3.3 The Executive shall have a fiduciary duty to act only in the best
interest of the Enamelon Group and acknowledges that he owes the Enamelon Group
a high degree of trust and loyalty. While he is employed by the Company, the
Executive shall not take any action which would harm or detrimentally impact
upon the Enamelon Group's business.

         3.4 At all times during the performance of this Agreement, the
Executive shall strictly adhere to all policies, rules and regulations that have

shall be subject to the direction and control of, Dr. Steven R. Fox, the
Chairman of the Board and Chief Executive Officer of the Company.

         3.5. In order to induce the Company to enter into this Agreement, the

by virtue of any agreement or arrangement or by virtue of any law or rule or
otherwise which would impair the Executive's right or ability (i) to enter the
employ of the Company, or any other member of the Enamelon Group or (ii) to
perform fully his duties and obligations pursuant to this Agreement.

         4.                Compensation.

salary of $200,000 per year, subject to adjustment from time to time as
determined by the Board of Directors (the "Salary"), and (ii) a bonus to be
determined annually by the Board of Directors of the Company (the "Bonus").

         4.2 The Company shall pay the Executive's Salary in equal bi-weekly
installments and shall pay the Executive's Bonus earned with respect to any
period at such time or times as the Board of Directors of the Company shall
determine. All payments of Salary and Bonus shall be subject to all withholding
and other employment taxes required by law, which shall be withheld and paid by
the Company in accordance with its normal payroll practices.

         4.3 The Company shall grant the Executive as of the date hereof options
to purchase 100,000 shares of the Company's Common Stock in accordance with the
terms of the Company's 1997 Incentive Stock Option Plan (the "1997 Plan") at an

         5.1 The Executive shall be entitled to four weeks of paid vacation per

         6.                Expenses.
                           --------

         6.1 As a condition of his employment, the Executive shall maintain an
automobile. Accordingly, the Company shall lease an automobile for the
Executive's use, the payments for which shall not exceed $500 per month. In
addition, the Company shall pay or reimburse the Executive for tolls, parking,
gasoline, maintenance and other expenses incurred in connection with the
performance of his duties hereunder, which shall be paid upon presentation of
original invoices.

         6.2 The Executive shall be authorized to incur other ordinary and
necessary business expenses in connection with the performance of his duties
hereunder, including travel expenses and entertainment expenses, as shall be
authorized by the Chairman or Chief Executive Officer of the Company. Such
expenses shall be reimbursed only upon presentation of paid receipts and/or
original invoices and such other information as shall be required for tax
purposes.

         6.3 If any salary payment, medical reimbursement, fringe benefit,
expense allowance payment, or other expense incurred by the Company for the
benefit of the Executive is disallowed in whole or in part as a deductible
expense of the Company for federal income tax purposes, the Executive shall
reimburse the Company, upon notice and demand, to the full extent of the
disallowance. This legally enforceable obligation is in accordance with the
provisions of Revenue Ruling 69-115 and is for the purpose of entitling the
Executive to a business expense deduction for the tax year in which the
repayment is made to the Company. In this manner, the Company shall be protected
from having to bear the entire burden of a disallowed expense item.

         7.                Sick Leave; Disability.
                           ----------------------

         7.1 The Executive shall be entitled to annual paid sick leave in length
to conform with the Company's general employment practices for executive
officers.

         7.2 If the Executive is unable to perform his duties hereunder by
reason of physical or mental incapacity or infirmity (a "Disability") for a
period of 90 consecutive days or a period of 180 days during any consecutive
12-month period or the earlier appointment of a guardian, conservator or
committee for his person, then the Executive shall be "Disabled " for purposes
of this Agreement and the period of his Disability as provided above shall be
referred to herein as the "Disability Period". The existence of a Disability
hereunder shall be determined by a licensed physician selected by the Company,
subject to the consent of the Executive, which consent shall not be unreasonably
withheld, and the Executive hereby consents to an examination by such physician
for such purpose. During the Disability Period, the Company shall continue to
pay the Executive the Salary earned hereunder; provided, however, that such
payments shall be reduced by the amount of any disability income payments the
Executive receives during the Disability Period under any policy carried by the
Company of which the Executive is the

                                        4

<PAGE>




beneficiary. The Company shall have the right to terminate this Agreement and
the Executive's employment hereunder for Disability at any time after the end of
the Disability Period.

         8.                Death During Employment.
                           -----------------------

                           If the Executive shall die during the Term, the 
Company shall pay to the estate of the Executive the Salary that would otherwise
be payable to the Executive up to the date of his death. The Company shall have
no further obligation to the Executive's estate.

         9.                Termination.
                           -----------

         9.1 The Company shall have the right to terminate the Executive's
employment for Cause (as hereinafter defined in Subsection 9.2) at any time,
which termination shall be effective immediately upon the Company's giving
notice to the Executive setting forth in reasonable detail the grounds therefor.
If the Executive's employment is terminated for Cause, the Company shall pay to
the Executive within 45 days after such termination, all accrued Salary earned
through the date of termination. The Executive hereby specifically acknowledges
that upon termination of his employment for Cause, he shall have no right to
receive any other payments provided for under this Agreement.

         9.2 For purposes of this Agreement, any of the following actions or
events shall constitute grounds for termination of the Executive's employment
for "Cause":


         (i) the Executive's neglect or refusal to perform, or if he otherwise
fails to perform, his duties as an executive officer and employee of the
Company.

         (ii) any other conduct constituting a breach of this Agreement or of
any code of conduct heretofore or hereafter adopted by the Company or the
Enamelon Group;

         (iii) the Executive's conviction (including a conviction on a nolo
contendere plea) of a felony or misdemeanor (other than minor traffic offenses);

         (iv) any willful, intentional, or grossly negligent act having the
effect of significantly injuring the Executive's reputation or the reputation or
business of the Enamelon Group; or

relative to or in connection with the performance of his duties

                                        5

<PAGE>

hereunder (including, without limitation, the Executive's inability to perform
his duties hereunder as a result of chronic alcoholism or drug addiction).

         9.3 The Company shall have the right to terminate the Executive's
employment without Cause at any time, which termination shall be effective 30
days after the Company gives notice thereof to the Executive. If the Executive's
employment is terminated by the Company on or prior to the first anniversary of
this Agreement without Cause and other than as a result of his death or
Disability, the Company shall pay, and the Executive shall accept, one week of
Executive's Salary for each calendar month or part thereof served hereunder
through the date of termination as full compensation for all obligations due to
the Executive. If the Executive's employment is terminated after the first
anniversary of this Agreement without Cause and other than as a result of the
Executive's death or Disability then, and in such event, the Company shall pay
the Executive, and the Executive shall accept, as full compensation for all
obligations due to the Executive, an amount equal to one-half of his annual
Salary, which amount shall be paid in six equal monthly installments commencing
one month after the effective date of termination. The Executive hereby
specifically acknowledges that upon such termination of his employment, he shall
have no right to receive any other payments provided for under this Agreement.

         9.4 If the Executive voluntarily terminates his employment with the
Company (for any reason whatsoever), the Company shall pay to the Executive his
accrued Salary through the date of termination. The Executive hereby
specifically acknowledges that upon voluntary termination of his employment, he
shall have no right to receive any other payments otherwise provided for under
this Agreement.

         9.5 If the Executive's employment is terminated for Disability or
death, then the Company shall pay to the Executive or his personal
representatives, legatees, appointees or distributees, as the case may be, his
accrued Salary earned through the date of termination.

         9.6 Notwithstanding anything contained herein to the contrary, if
during the Post-Termination Period (as hereinafter defined in Subsection 10.2)
the Executive obtains other employment or engages in his own business or
otherwise engages in any business activities for his own benefit or account, the
Executive shall immediately notify the Company, and an amount equal to the
Executive's total salary, compensation, and other income during such period from
such other employment, business or business activities shall be applied pro
tanto in reduction to any amounts payable under this Section 9 during the
Post-Termination Period.

         10.      Restrictive Covenants.
                  ---------------------

         10.1 The Executive acknowledges that (i) the business activities of the

                                        6

Accordingly, the Executive agrees as follows:

throughout the Employment Period and the Post-Termination Period (as such terms
are defined in Subsection 10.2) the Executive shall not, directly or indirectly,
(i) engage, in any country in the world in which the Company is engaged in
business, in any business in which the Company is engaged or in which the
Company is planning to engage, in each case at the beginning of the Post-
Termination Period (a "Competing Business") or (ii) without limiting the
generality of clause (i) above, be or become, or agree to be or become,
interested in or associated with, in any capacity (including, without

principal, agent, creditor, trustee, consultant, co-venturer or otherwise), any
individual, corporation, firm, association, partnership, joint venture or other
business entity, which is engaged in or which is planning to engage in any
Competing Business; provided, however, that the Executive may own, solely as an
investment, securities of any publicly held corporation traded on any national
securities exchange in the United States of America, if the Executive is not a
controlling person of or member of a group that controls, such corporation and
does not, directly or indirectly, own more than 1% of any class of securities of
such corporation.

         10.1.2 Throughout the Employment Period and the Post-Termination
Period, the Executive shall not, directly or indirectly (i) induce or attempt to

of the Enamelon Group during any portion of such period to transact business
with a competitor of the Enamelon Group in a Competing Business.

         10.1.3 Throughout the Employment Period and thereafter, the Executive
shall not disclose to anyone any information about the affairs of any member of
the Enamelon Group, including without limitation, trade secrets, inventions,
customer lists, client lists, business plans, operational methods, pricing
policies, marketing plans, sales plans, identity of suppliers, or other

                                        7

<PAGE>

financial information not publicly disclosed and which is confidential to the
Enamelon Group or is not generally known in the relevant trade (collectively,
"Proprietary Information"), regardless of whether the Executive developed such
Proprietary Information, nor shall the Executive make use of any such
Proprietary Information for his own benefit.

         10.2 For the purposes of this Agreement the following terms shall have
respective meanings ascribed to them below:

         10.2.1 "Employment Period" means the period of the Executive's
employment by the Company, including such period of employment, if any,
extending beyond the Term.

         10.2.2 "Post-Termination Period" means the two-year period commencing
with the end of the Employment Period.

         10.2.3 "Restrictive Covenants" means any of the provisions of 
Subsection 10.1 hereof.

         10.3 If the Executive breaches, or threatens to commit a breach of, any
of the Restrictive Covenants, the Company shall have the following rights and
remedies, each of which shall be independent of the others and severally
enforceable, and each of which is in addition to, and not in lieu of, any other
rights and remedies available to the Company at law or in equity:

         10.3.1 The Executive shall account for and pay over to the Company all
compensation, profits, monies, accruals and other benefits derived or received
by the Executive or any person or business entity affiliated with the Executive
as a result of any action or transactions constituting a breach of any of the
Restrictive Covenants.

         10.3.2 Notwithstanding the provisions of Subsection 10.3.1 above, the
Executive acknowledges and agrees that in the event of a violation or threatened
violation of any of the Restrictive Covenants, the Company shall have no
adequate remedy at law and shall therefore be entitled to enforce each provision
by temporary or permanent injunctive or mandatory relief obtained in any court
of competent jurisdiction without the necessity of proving damages, posting any
bond or other security, and without prejudice to any other rights and remedies
which may be available at law or in equity.

         10.4 If any of the Restrictive Covenants, or any part thereof, is held
to be invalid or unenforceable, the same shall not affect the remainder of the
covenant or covenants, which shall be given full force and effect, without
regard to the invalid or unenforceable portions.

         10.5 If any of the Restrictive Covenants, or any part thereof, is held
to be unenforceable because of the duration of such provision or the area
covered thereby, the parties

                                        8

<PAGE>

hereto agree that the court making such determination shall have the power to
reduce the duration and/or area of such provision and, in its reduced form, such
provision shall then be enforceable.

         10.6 The parties hereto intend to and hereby confer jurisdiction to
enforce the Restrictive Covenants upon the courts of any jurisdiction within the
geographical scope of such Restrictive Covenants. In the event that the courts
of any one or more of such jurisdictions shall hold such Restrictive Covenants
wholly unenforceable by reason of the breadth of such scope or otherwise, it is
the intention of the parties hereto that such determination not bar or in any
way affect the Company's right to the relief provided above in the courts of any
other jurisdictions within the geographical scope of such Restrictive Covenants,
as to breaches of such covenants in such other respective jurisdictions, the
above covenants as they relate to each jurisdiction being, for this purpose,
severable into diverse and independent covenants.

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

Company, its Subsidiaries, and their respective businesses that may be
considered "inside information" for purposes of the Securities Act of 1933 and
the Securities Exchange Act of 1934 and the Rules and Regulations promulgated
thereunder. The Executive acknowledges that his purchase or sale securities of
the Company while in possession of such inside information or his informing any
other person of such inside information for the purpose of purchasing, selling
or otherwise dealing in securities of the Company is prohibited by law and shall
constitute a breach of this Agreement and a basis for termination of the
Executive's employment for Cause.

         12.               Inventions.
                           ----------

learned of or reduced to practice by the Executive, either alone or with others,
whether the activity in question takes place within or outside the usual working
hours of the Executive or on or off the premises of the Company, shall be held
by the Executive for the exclusive benefit of the Company, and the Executive
shall assign in writing to the Company, without any payment being required on
the part of the Company, all of the right, title and interest that he may have
acquired in and to any Inventions. In addition, he shall, both during and at any
time prior to three (3) years after the Employment Period, assist the Company in
every way reasonably requested by the Company, at the expense of the Company

tangible embodiments or evidence of Proprietary Information or Inventions, and
all copies of the foregoing ("Materials"), that may at any time be acquired by
or come into the possession of the Executive are the sole and exclusive property
of the Company. All Materials shall be surrendered to the Company upon the
request by the Company at any time. In addition, upon the reasonable request by
the Company at any time, the Executive shall prepare Materials accurately and
adequately to describe, set forth or embody any Proprietary Information or
Inventions and deliver the same to the Company in order to accomplish or
complete the transfer thereof to the Company, and the Executive shall be

other action as the Company may reasonably require (being reimbursed for all of
his reasonable out-of-pocket expenses in this connection) in order to assign the
Company any and all copyrights and reproduction rights to any Materials prepared
by him during and in connection with such employment.

examinations, and by filling out, executing and delivering such applications and
other instruments in writing as may be reasonably required by an insurance
company or companies to which an application or applications for such insurance
may be made by or for the Company. In order to induce the Company to enter into
this Agreement, the Executive represents and warrants to the Company that to the
best of his knowledge the Executive is insurable at standard (non-rated)
