                                     Part I

Item 1.  Business

  IGI, Inc. ("IGI" or the "Company") was incorporated in Delaware in 1977.  Its
executive offices are at Wheat Road and Lincoln Avenue, Buena, New Jersey.  The
Company is a diversified company engaged in two business segments:

 . Animal Health Products Business - production and marketing of animal health
  -------------------------------                                            
  products such as poultry vaccines, veterinary products, nutritional
  supplements and grooming aids; and

 . Cosmetics and Consumer Products Business - production and marketing of
  ----------------------------------------                              
  cosmetic and consumer products such as skin care products and shampoos.

  Since 1987, the earnings from the Company's Animal Health Products Business
have been used to fund commercial development efforts in the Cosmetics and
Consumer Products Business and the Company's former Biotechnology Business which
was engaged in the business of development of various applications of the
Company's proprietary encapsulation technology (Novasome(R) lipid vesicle and
Ultrasponge/TM/ hydrogel technologies and micellar nanoparticles, the "Novavax
Technologies") primarily for human medicines and vaccines.

Distribution of Biotechnology Business
- --------------------------------------

  On March 17, 1994, the Company's Board of Directors adopted a plan to dispose
of the Biotechnology Business by spinning it off through a distribution to the
Company's stockholders of all of its common stock of the separate entity which
would conduct the Biotechnology Business in the future.  Since 1991, the
development efforts of the Biotechnology Business were directed primarily
towards human pharmaceuticals, including vaccines.  These development efforts
had reached the level where separate funding sources were required for the
Biotechnology Business to continue its development efforts, meet the
requirements of the FDA approval process and reach the stage of eventual
commercialization.

  The Board of Directors determined that the best interests of the Company and
its stockholders would  be served by dividing the Company into two separate
publicly-traded entities.  By doing so, the Board of Directors believed that
access of both IGI and the Biotechnology Business to the capital markets would
significantly improve; IGI would be able to focus on its historically profitable
and growing Animal Health Products Business and its growing Cosmetics and
Consumer Products Business; and the management of the Biotechnology Business
would be able to focus mainly on developing human pharmaceutical applications.
The Company believed that the Distribution would also simplify IGI and permit
investors to more readily evaluate the earnings and growth potential of the
separate companies.

  On December 12, 1995 (the "Distribution Date"), IGI distributed to the holders
of record of IGI's common stock, at the close of business on the Record Date,
November 28, 1995, one share of common stock of Novavax, Inc. ("Novavax") for
every one share of IGI common stock outstanding (the "Distribution").  In
connection with the Distribution, the Company has paid Novavax $5,000,000 in
return for a fully paid-up, ten-year license entitling it to the exclusive use
of Novavax's technologies in the fields of (i) animal pharmaceuticals,
biologicals, and other animal 

                                                                               1
<PAGE>
 
health products; (ii) foods, food applications, nutrients and flavorings; (iii)
cosmetics, consumer products and dermatological over-the-counter and
prescription products (excluding certain topically delivered hormones); (iv)
fragrances; and (v) chemicals, including herbicides, insecticides, pesticides,
paints and coatings, photographic chemicals and other specialty chemicals; and
the processes for making the same. The Company has the option, exercisable
within the last year of the ten-year term, to extend the License Agreement for
an additional ten-year period for $1,000,000. Novavax will retain the right to
use its Novavax Technologies for all other applications, including human
vaccines and pharmaceuticals. The Company has presented the payment under the
License Agreement as a capital contribution in its financial statements to
reflect the intercompany nature and substance of the transaction. The form was
structured as a prepaid licensing agreement to address various considerations of
the Distribution, including tax and financing considerations. For tax purposes,
the transaction will be treated as a prepaid licensing agreement. IGI has no
further obligations to fund Novavax. See Note 2 of Notes to IGI Financial
Statements.

  IGI funded the $5,000,000 payment to Novavax from borrowings under its bank
loan agreement which has been amended to reflect the Distribution.  The Amended
Loan Agreement with Fleet Bank - NH and Mellon Bank provides for:

 . $12,000,000 revolving credit facility with interest contingent upon certain
  financial ratios at the end of each quarter.  The interest rate shall not
  exceed prime plus 1 1/2%.  The amount available under the revolving credit
  facility decreases by $800,000 on the last day of each quarter from June 30,
  1996 through December 31, 1999.  At March 22, 1996 the Company had outstanding
  borrowings of $12,000,000 under this facility and the interest rate was 10%.

 . $10,000,000 working capital line of credit renewable annually, with
  interest on the outstanding borrowings contingent upon certain financial
  ratios at the end of each quarter.  The interest rate shall not exceed prime
  plus 1%.  At March 22, 1996, the Company had $1,615,000 available under this
  facility and the interest rate was 9.5%.

  The Company was in default of its current ratio covenant as of December 31,
1995.  The banks have amended the agreement to remove the default.

  Under a transition services agreement, IGI will continue to provide certain 
administrative services to Novavax, including services relating to human 
resources, purchasing and accounting, data processing and payroll services for a
period not to extend beyond June 30, 1996. Novavax will pay IGI a fee for all 
services provided by IGI employees, based on IGI's cost. In addition to these 
services, Edward B. Hager will serve as Chairman of the Board and Chief 
Executive Officer and John P. Gallo will serve as Chief Operating Officer and 
Treasurer of Novavax through no later than June 30, 1996 (the "Transition 
Termination Date"). Prior to the Transition Termination Date, Dr. Hager will 
continue to devote the majority of his time to IGI and will receive no 
compensation for his services as an officer of Novavax. Mr. Gallo will devote 
approximately one half of his business time through the Transition Termination 
Date to Novavax and its business, and IGI and Novavax will each pay Mr. Gallo 
one half of his annual compensation. The Company does not believe that its 
reliance on part-time management by Mr. Gallo will adversely affect IGI's 
business during the transition period.

  As a result of the Distribution, the Consolidated Financial Statements of IGI
present its Biotechnology Business as a discontinued operation.  Losses incurred
by the Biotechnology Business through the date of the Distribution are included
in the "Loss from Discontinued Operations" in the financial statements.

Strategy
- --------

  The Company's business strategy for its operations is as follows:

 . Continue growth of the Animal Health Products Business, especially in the
  international markets, through new product development and intensified product
  registration (for licenses in foreign countries) and marketing efforts.

                                                                               2
<PAGE>
 
 . Continue growth of the Cosmetics and Consumer Products Business through
  expanded efforts to develop and market additional cosmetic and dermatologic
  products utilizing the Novavax Technologies internally through the Company's
  Nova Skin Care Division and externally through industry partners and
  customers.

 . Continue development of the consumer product applications of the Novavax
  Technologies, including flavors, beverage and food additives, coatings, paints
  and chemicals.

 . Explore opportunities for strategic acquisitions in its two business
  segments.

Novavax Technologies
- --------------------

  Liposome encapsulation is a process designed to entrap and deliver various
useful materials.  Prior to the development of the Novavax Technologies, the
most commonly used technology, phospholipid liposome encapsulation, had a
limited capacity to encapsulate anything other than materials that can be
dissolved or suspended in water.  Phospholipid liposomes are man-made,
microscopic spheres that are usually formed through a multi-step process, which
generally includes the mixing of water, organic solvents and phospholpids.  Most
phospholipid-based liposomes are produced from materials that are expensive and
may require the use of potentially hazardous organic solvents.  The standard,
multi-step phospholipid manufacturing process yields small quantities of
expensive, less stable vesicles with limited cargo capacity.

  Based on the belief that certain forms of liposomes can stimulate the immune
system, various institutions and companies have tried to develop liposome-based
vaccines with advantageous properties over conventional vaccines.  The Company
believes that efforts to commercially develop phospholipid-based liposomes have
been unsuccessful primarily because phospholipid-based liposomes have:

 .  high cost
 .  low stability
 .  low versatility
 .  commercial scale-up difficulties

Novasome Lipid Vesicles

  While artificial lipid vesicle encapsulation technology has existed for almost
four decades, the Company believes that it was one of the first companies to
produce highly stable, versatile artificial lipid vesicles and structures of
various types from low-cost, readily available materials in commercial
quantities.  The major advantages of Novasomes over other liposomes are as
follows:

     Versatility, Stability and Low Cost

 . Novasomes may be made from a number of inexpensive, readily available
  chemicals, called amphiphiles, including fatty alcohols and acids, ethoxylated
  fatty alcohols and acids, glycol esters of fatty acids, glycerol fatty acid
  mono and diesters, ethoxylated glycerol fatty acid esters, glyceryl ethers,
  fatty acid diethanolamides and dimethyl amides, fatty acyl sarcosinates,
  "alkyds" as well as phospholipids.

                                                                               3
<PAGE>
 
 . Novasomes have a large, stable central core that allows them to entrap and
  deliver a wide variety of substances that may be too large or disruptive for
  phospholipid vesicles, including lipids, solvents, particulates and
  perfluorocarbons as well as aqueous materials.

 . Novasomes can be varied according to the intended cargo and can be
  engineered to release cargo in response to a variety of factors.

 . Novasomes can be made to provide acceptable stability under a variety of
  conditions, such as wide variations of alkalinity, acidity, temperature,
  shear, detergents, solvents, enzymes and others.

     Ease of Commercial Scale-up

  Novasomes can be made in large quantities in a continuous flow process that
does not use organic solvents.  The patented Novamix/TM/ production machinery
permits the blending of reagents under controlled conditions, and enables the
composition of the Novasomes to be adjusted to customize their structure and
release properties.  The Novavax Technologies, the Company's ability to use
readily available materials and the patented Novamix production machinery allow
it to produce Novasomes  with stability, versatility, large cargo carrying
capacity, high production volumes and low production costs.  The Company
believes these advantages provide an opportunity to extend the commercial
potential of Novasomes from the near-term cosmetic and personal care products
produced and marketed by IGI.

     Micellar Nanoparticles

  Micellar nanoparticles ("MNP") are submicron-sized lipid structures.  MNP have
different structural characteristics (e.g. do not have lipid bilayers) and are
generally smaller than Novasome lipid vesicles.  MNP, like Novasomes, are made
from the family of materials derived from amphiphilic surfactants and can be
tailored for particular uses.  They exhibit encapsulating and many other
properties similar to Novasomes, but differ in other properties.  MNP are very
stable and can be prepared in commercial quantities at a reasonable cost.  The
Company believes MNP may have commercial application in its Cosmetic and
Consumer Products.

  Novavax holds 30 U.S. patents and 43 foreign patents covering its Novavax
Technologies (including a wide variety of component materials, its continuous
flow vesicle production process and its Novamix/TM/ production equipment).

License of Technology from Novavax
- ----------------------------------

  On December 12, 1995, IGI, Inc. distributed its majority interest in Novavax
to the IGI stockholders.  Immediately after the Distribution, IGI, through its
wholly-owned subsidiary IGEN, Inc., paid Novavax's wholly-owned subsidiary
Micro-Pak, Inc. approximately $5,000,000 in return for a fully paid-up,
exclusive ten-year license entitling it to use the Novavax Technologies in the
fields (the "IGI Field") of (i) animal pharmaceuticals, biologicals and other
animal health products; (ii) foods, food applications, nutrients and flavorings;
(iii) cosmetics, consumer products and dermatological over-the-counter and
prescription products (excluding certain topically delivered hormones); (iv)
fragrances; and (v) chemicals, including herbicides, insecticides, pesticides,
paints and coatings, photographic chemicals and other specialty chemicals; 

                                                                               4
<PAGE>
 
and the processes for making the same (the "IGI License Agreement"). IGI has the
option, exercisable within the last year of the ten-year term, to extend the
exclusive license for an additional ten-year period for $1,000,000. Novavax will
retain the right to use its Novavax Technologies for all applications outside
the IGI Field, including human vaccines and pharmaceuticals.

  If at any time during the term of the IGI License Agreement either party shall
make or discover any product improvements useful in the IGI Field (such
improvements being limited to those improvements that would be dominated by the
claims of a licensed patent), it shall communicate all details in respect
thereof to the other party.  If Novavax makes such improvements, IGI shall be
entitled to use the same in the IGI Field during the term of the IGI License
Agreement without paying any increased royalty in respect thereof.  If IGI makes
such improvements, Novavax shall have the right to use them outside the IGI
Field during the term of the IGI License Agreement.  In the event employees of
Novavax and IGI are joint inventors as a result of inventions arising out of the
development of licensed products, any patent applications filed thereon shall be
owned by Novavax, and IGI shall have an exclusive license in the IGI Field.

  Three of the members of the Board of Directors of IGI are also directors of
Novavax, and the terms of the IGI License Agreement were unilaterally
established by IGI.  [It is the view of the Board of Directors and management of
Novavax, however, that the terms of the IGI License Agreement were at least as
favorable to Novavax as would have been obtained from any unaffiliated third
party.]  The $5,000,000 license payment was determined unilaterally by IGI,
based on the present value of the estimated aggregate royalties IGI would expect
to pay Novavax over a ten-year period if such royalties were paid annually based
on IGI's annual revenues from the sale of its products that use or incorporate
the Novavax Technologies.  The royalty rates used in calculating the license
payment were the same as those used by IGI in determining the annual royalties
paid by IGI for the Novavax Technologies when the Company was a subsidiary of
IGI during the period prior to the Distribution.  Prior to the Distribution, IGI
paid a royalty rate of 10% on sales of products incorporating the Novavax
Technologies.  This rate was determined based on a review of similar types of
licensing agreements and reflected the lack of any up-front payment by IGI to
Novavax.  Novavax recognized revenues under its earlier license agreement of
$199,000, $210,000 and $268,000 for the years 1993, 1994 and 1995, respectively.
The lump sum license payment was determined to be preferable to annual royalty
payments, because the license payment would provide Novavax with immediate funds
to finance its operations after the Distribution.  At the time the terms of the
IGI License Agreement were fixed, including the license payment, all of the
directors of IGI were also directors of Novavax.

                                                                               5

  As a result of the Distribution of the Biotechnology Business, the operating
losses of that segment are included as "Loss from Discontinued Operations" in
the Company's financial statements.  (See Note 2 of Notes to Consolidated
Financial Statements.)

Animal Health Products Business
- -------------------------------

  IGI manufactures and markets a broad range of animal health  products used in
pet care and poultry production.  The Company sells these products in the United
States and over 50 other countries principally under two trade names:  Vineland
Laboratories and EVSCO Pharmaceuticals.  The Company also sells veterinary
products to the over-the-counter pet products market under the Tomlyn label.

Poultry Vaccines
- ----------------

  The Company produces and markets poultry vaccines manufactured by the chick
embryo, tissue culture and bacteriological methods.  The Company produces
vaccines for the prevention of various chicken and turkey diseases and has 80
vaccine licenses granted by the United States Department of Agriculture ("USDA")
(See "Government Regulation").  The Company also produces and sells, under its
Vineland Laboratories label, nutritional, anti-infective and sanitation products
used primarily by poultry producers.

  The Company manufactures poultry vaccines at its USDA approved facility in
Vineland, New Jersey and sells them, primarily through its own sales force of 12
persons, directly to large poultry producers and distributors in the United
States and, through its export sales staff, to local distributors in other
countries.  The sales force is supplemented and supported by technical and
customer service personnel.  The Company's vaccine production in the  United
States is regulated by the USDA.  Sales of poultry vaccines and related products
accounted for approximately 60% of the Company's sales in 1995, 59% in 1994 and
58% in 1993.

                                                                               6
<PAGE>
 
  The Company has two poultry vaccines licensed by the USDA which use the
Novavax Technologies and is continuing development efforts on new vaccine
applications of this technology.

  The Company's principal competitors in the poultry-vaccine market are Intervet
America, Inc., Solvay Veterinary, Inc. and Rhone-Merieux Select Laboratories,
Inc.  The Company believes that it has the largest share of the domestic poultry
vaccine market.  The Company competes on the basis of product performance,
price, customer service and availability.

Veterinary Products
- -------------------

  The EVSCO line of veterinary products is used by veterinarians in caring for
dogs and cats, and includes antibiotics, anti-inflammatories, cardiac care
drugs, nutritional supplements, vitamins, insecticides and diagnostics.  Product
forms include gels, tablets, creams, liquids, ointments, powders, emulsions and
diagnostic kits.  EVSCO also produces professional grooming aids for dogs and
cats.

  EVSCO products are manufactured at the Company's facility in Buena, New Jersey
and sold through distributors to veterinarians.  The facility operates in
accordance with Good Manufacturing Practices ("GMP") of the federal Food and
Drug Administration ("FDA") (See "Government Regulation".)  Principal
competitors of the EVSCO product line include Solvay Veterinary, Inc., Vet-Kem,
a division of Sandoz Pharmaceuticals Corp., MSD AGVET (a division of Merck &
Co.), Schering Corp., and Pitman-Moore, Inc.  The Company competes on the basis
of price, marketing, customer service and product qualities.

  The Tomlyn product line includes pet grooming, nutritional and therapeutic
products, such as shampoos, grooming aids, vitamin and mineral supplements,
insecticides and OTC medications.  These products are manufactured at the
Company's facility in Buena, New Jersey, and sold through distributors to
superstores, independent merchandising chains, shops and kennels.  Tomlyn's
largest selling product line is the Nova Pearl/TM/ line of shampoos which is
based upon the Novavax Technologies and provides combined moisturizing, cleaning
and conditioning.

  Sales of the Company's veterinary products are handled by 24 sales employees.
Most of the Company's veterinary products are sold through distributors.  Sales
of veterinary products accounted for approximately 35% of the Company's sales in
1995, 36% in 1994 and 37% in 1993.

Cosmetics and Consumer Products
- -------------------------------

  IGI's Cosmetics and Consumer Products division is focused on the internal
development and marketing of skin care products utilizing the Novavax
Technologies through its Nova Skin Care division.  IGI is continuing to work
with several cosmetics, personal care products, and OTC pharmaceutical companies
for various commercial applications of Novavax Technologies.  Because of their
ability to encapsulate skin protective agents, oils, moisturizers, shampoos,
conditioners, skin cleansers and fragrances and to provide both a controlled and
a sustained release of the encapsulated materials, Novasome lipid vesicles are
well-suited to cosmetics and consumer product applications.  For example,
Novasomes may be used to deliver moisturizers and other active ingredients to
the deeper layers of the skin or hair follicles for a prolonged period; to
deliver or preserve ingredients which impart favorable cosmetic characteristics

                                                                               7
<PAGE>
 
described in the cosmetics industry as "feel," "substantivity," "texture" or
"fragrance"; to deliver normally incompatible ingredients in the same
preparation, with one ingredient being shielded or protected from the other by
encapsulation within the Novasome; and to deliver pharmaceutical agents to
and/or through the skin.

  The Company is presently producing Novasomes for various skin care products
including those marketed by the Prescriptives Division of Estee Lauder under
that company's "All You Need" brand name as well as products for Lauder's
"Resilience" brand.  The first product was introduced in early 1993.  The
Company also produces and sells Novasomes to Revlon for use in lines of skin
moisturizers manufactured and marketed by Revlon as its "Results" product line
and by Revlon's Almay Division in its "Time Off" product line.

  Sales of the Company's Cosmetics and Consumer Products were principally based
on formulations using the Novavax Technologies.  Such sales approximated 5% in
each of 1995, 1994 and 1993 of the Company's total sales.

     Nova Skin Care

  In February 1996, under the Nova Skin Care label, IGI launched its own line of
Novasome(R) based alpha hydroxy acid skin care products.  The first six over-
the-counter products were introduced at the annual meeting of the American
Academy of Dermatology in February 1996.  The Company is marketing these
products directly to dermatologists through a sales force of 16 employees.
Additions to this product line are planned for 1996.

  On February 6, 1996, Johnson & Johnson and its wholly-owned subsidiary Ortho-
McNeil, Inc. (collectively, "J&J") filed a lawsuit against the Company and its
subsidiary, Igen, Inc. and its former subsidiary Micro-Pak, Inc. in the United
States District Court for the District of New Jersey alleging trademark
infringement and trademark dilution. J&J alleges that the Company's use of the
names NOVA SKIN, NOVA SKIN CARE, and NOVA-AESTHETICS infringes on rights
associated with J&J's trademark RENOVA for a prescription drug. J&J has also
moved for a preliminary injunction seeking to preclude the Company's use of the 
NOVA SKIN, NOVA SKIN CARE, and NOVA-AESTHETICS names on the Company's 
newly-launched line of skin care products sold through dermatologists. On March 
18, 1996, following a period of expedited discovery, the Court held an 
evidentiary hearing on the motion for preliminary injunction. The Court has not 
yet issued a ruling.

  Since 1988, the Company has used the trademark NOVASOME in connection with the
lipid vesicle encapsulation technology it developed, including in connection 
with skin care products. In addition, numerous other companies use the term 
NOCVA in a wide variety of product and corporate name formulations. The Company 
is vigorously defending this lawsuit and believes that the outcome of the 
proceedings will not have a material adverse effect on the Company's financial 
position or results of operations. 

     Other Applications

  The versatility of the Novavax Technologies combined with the Company's
commercial production capabilities allow the Company to target large, diverse
markets.  Through product collaborations and license agreements, the Company is
seeking to develop additional products for this business segment.  For example,
in 1992, the Company entered into a joint venture using the  Novavax
Technologies, ("Flavorsome, Ltd."), to develop encapsulated flavors for foods
and beverages.  Flavorsome is working with a number of food industry leaders on
various food, beverage and confection applications of the Novavax Technologies.
During 1995, Flavorsome received its first commercial orders.  The Company
continues to pursue the development of food, beverage and confection
applications of Novavax Technologies.  A major goal of Novasome flavor
preservation is to double or triple the useful shelf life of various foods,
beverages and candies which are dependent on volatile flavors.  The Novavax
Technologies enables the 

                                                                               8

substitution of encapsulated, water or other calorie neutral material for fat in
confections. Other benefits include encapsulation of beverage flavors to give a
sequential taste phenomenon, development of higher melting point chocolate and
taste masking of nutritional supplements. The Company is evaluating affiliations
with potential industry partners. The efforts for the development of additional
products require extensive testing, evaluation and trials, and therefore no
assurance can be given that commercialization of these products with Novasomes
will be successful.

  The Company has also developed a Novasome-encapsulated anthralin preparation
("Anthrasome Cream") for the treatment of psoriasis.  Anthralin is an effective
medication for the treatment of psoriasis.  However, it causes skin staining,
and because of its customary petrolatum-based formulation and insolubility, has
generally been a difficult substance to formulate in a cosmetically acceptable
form.  The Company believes its Novasome cream formulation is more cosmetically
acceptable and reduces skin staining.  The Company is seeking to market
Anthrasome Cream through an arrangement with a third-party.

  The Company has encapsulated retinoids in Novasome vesicles in collaboration
with J&J.  Retinoids are derivatives of retinoic acid and are effective in the
treatment of acne and thought to be effective in the treatment of various age-
associated skin disorders.  Encapsulation of retinoids in Novasomes is designed
to prolong stability and reduce irritation and provide a sustained release of
certain active ingredients to treat these disorders.  The Company does not
expect to derive any significant revenue from this application during 1996.

International Sales and Operations
- ----------------------------------

  A staff of 12 persons based in Buena, New Jersey and 4 individuals based
overseas handle all sales of Company products outside the United States.  The
Company's sales personnel and poultry veterinarians travel abroad extensively to
develop business through local distributors.  Exports consist primarily of
poultry vaccines, although the Company also exports some veterinary
pharmaceuticals and pet care products.  Exports of vaccines require product
registration or licensing by foreign authorities.  The Company has 519 products
registered or licensed in over 50 countries outside the United States and has
over 1,328 registrations pending.

  Mexico and certain Latin American countries are important markets for the
Company's poultry vaccines and other products.  These countries have
historically experienced varying degrees of political unrest and economic and
currency instability.  Because of the volume of business transacted by the
Company in those countries, continuation or the recurrence of such unrest or
instability could adversely affect the businesses of its customers in those
countries or the Company's ability to collect its receivables from such
customers, which in either case could adversely impact the Company's future
operating results.

  In 1995, sales to international customers of $12,234,000 represented 39% of
the Company's sales, as compared with 39% in 1994 and 37% in 1993.  (See Note 11
of Notes to Consolidated Financial Statements.)

                                                                               9

Manufacturing
- -------------

  The Company's manufacturing operations include production and testing of
vaccines, lotions, pills and powders; packaging, bottling and labeling of the
finished products; and packing and shipment for distribution.  Approximately 78
employees are engaged in manufacturing operations.  The raw materials included
in these products are available from several suppliers.

  The Company produces quantities of Novasomes adequate to meet its current
needs for cosmetics and consumer product and animal health product applications.
In 1995, the Company completed and began operating a new facility for marketing
staff and Novavax Technologies product development.  This facility also houses
production facilities for cosmetics and consumer products.  The Company intends
to increase its poultry vaccine production capacity during 1996.  (See
"Properties".)

Research and Development
- ------------------------

  The Company's poultry vaccine research and development efforts are directed
towards developing more efficient single and multiple-component vaccines,
developing vaccines to combat new diseases and incorporating the Novavax
Technologies into existing vaccines.  The Company is concentrating its
veterinary pharmaceutical research and development efforts on the use of Novavax
Technologies for various veterinary pharmaceutical and OTC pet care products.
The Company's cosmetics and consumer products research and development efforts
are directed towards liposomal encapsulation to improve performance and efficacy
of cosmetics, consumer products, flavors and dermatologic products.  Under its
license agreement with Novavax, the Company has the right to continue to use the
Novavax Technologies to develop new products in those fields covered by the
license.

  In addition to its internal research and development efforts, which involves
23 employees, the Company encourages the development of products in areas
related to its present lines by making specific grants to universities.
Research expenses for  IGI's continuing operations were $1,345,000, $1,212,000
and $817,000 in 1995, 1994 and 1993, respectively.

Patents and Trademarks
- ----------------------

  All of the names of the Company's major products are registered in the United
States and all significant foreign markets in which the Company sells its
products.  Under the terms of the IGI License Agreement, IGI has an exclusive
ten-year license to use the Novavax Technologies in the IGI Field.  Novavax
holds 30 U.S. patents and 43 foreign patents covering its Novavax Technologies
(including a wide variety of component materials, its continuous flow vesicle
production process and its Novamix/TM/ production equipment).

  IGI intends to engage in collaborations, sponsored research agreements, and
preclinical and/or field testing agreements in connection with its future
vaccine and pharmaceutical products as well as clinical testing agreements with
academic and research institutions and U.S. government agencies, such as the
National Institutes of Health and the Department of Agriculture, to take
advantage of their technical expertise and staff and to gain access to clinical
evaluation models, patents, and related technology.  Consistent with
pharmaceutical industry and academic standards, and the rules and regulations
under the Federal Technology Transfer Act of 1986, these 

                                                                              10

agreements may provide that developments and results will be freely published,
that information or materials supplied by the Company will not be treated as
confidential and that the Company may be required to negotiate a license to any
such developments and results in order to commercialize products incorporating
them. There can be no assurance that the Company will be able successfully to
obtain any such license at a reasonable cost or that such developments and
results will not be made available to competitors of the Company on an exclusive
or nonexclusive basis.

Government Regulation
- ---------------------

  The production and marketing of the Company's products and its research and
development activities are subject to regulation for safety, efficacy and
quality by numerous governmental authorities in the United States and other
countries.  The Company's development, manufacturing and marketing of poultry
biologics are subject to regulation in the United States for safety and efficacy
by the United States Department of Agriculture ("USDA") in accordance with the
Virus Serum Toxin Act of 1914.  The development, manufacturing and marketing of
pharmaceuticals are subject to regulation in the United States for safety and
efficacy by the FDA in accordance with the Food, Drug and Cosmetic Act.

  In the United States, pharmaceuticals and vaccines are subject to rigorous
Food and Drug Administration ("FDA") regulation including preclinical and
clinical testing.  The process of completing clinical trials and obtaining FDA
approvals for a new drug or new biologic is likely to take a number of years,
requires the expenditure of substantial resources and is often subject to
unanticipated delays.  There can be no assurance that any product will receive
such approval on a timely basis, if at all.

  In addition to product approval, the Company may be required to obtain a
satisfactory inspection by the FDA covering the manufacturing facilities before
a product can be marketed in the United States.  The FDA will review the
manufacturing procedures and inspect the facilities and equipment for compliance
with applicable rules and regulations.  Any material change by the Company in
the manufacturing process, equipment or location would necessitate additional
FDA review and approval.

  Whether or not FDA approval has been obtained, approval of a pharmaceutical
product by comparable governmental regulatory authorities in foreign countries
must be obtained prior to the commencement of clinical trials and subsequent
marketing of such product in such countries.  The approval procedure varies from
country to country, and the time required may be longer or shorter than that
required for FDA approval.  Although there are some procedures for unified
filing for certain European countries, in general each country has its own
procedures and requirements.

  In addition to regulations enforced by the FDA, the Company also is subject to
regulation under the Occupational Safety and Health Act, the Environmental
Protection Act, the Toxic Substances Control Act, the Resource Conservation and
Recovery Act and other present and potential future federal, state or local
regulations.  The Company's research and development involves the controlled use
of hazardous materials, chemicals, viruses and bacteria.  Although the Company
believes that its safety procedures for handling and disposing of such materials
comply with the standards prescribed by state and federal regulations, the risk
of accidental contamination 

                                                                              11
<PAGE>
 
or injury from these materials cannot be completely eliminated. In the event of
such an accident, the Company could be held liable for any damages that result
and any such liability could exceed the resources of the Company.

Employees
- ---------

  The Company currently has 213 full-time employees, of whom 92 are in
marketing, sales and customer support, 78 in  manufacturing, 23 in research and
development, and 20 in executive, finance and administration.  Certain services
will be provided by IGI to Novavax through no later than June 30, 1996 on a
transitional basis while Novavax builds its support staff.  The Company has no
collective bargaining agreement with its employees, and believes that its
employee relations are good.

Item 2.  Properties

  The Company owns land and buildings housing offices, laboratories and
production facilities in four locations in New Jersey.  The Company also owns a
warehouse and sales office space in Gainesville, Georgia.  In addition, the
Company leases office space in Virginia and warehouses in New Jersey,
California, Mississippi, and Arkansas.

  The Company's poultry vaccine production facilities are located in Vineland,
New Jersey, where the Company owns several buildings situated on approximately
16 acres of land.  These buildings, containing 90,000 square feet of usable
floor space, house offices and facilities used for the production of poultry
vaccines.  They were constructed and expanded from time to time between 1935 and
1992.  The Company intends to renovate certain of these facilities in 1996 to
expand its vaccine production capacity to meet expected growth in existing
poultry vaccines and to provide production of new vaccines.

  In Buena, New Jersey, the Company owns a facility used for the production of
veterinary pharmaceuticals and cosmetics and consumer products.  The facility
was built in 1971 and expanded in 1975 and in 1992 its capacity was increased
for production of Novasome lipid vesicles.  The facility presently contains
41,200 square feet of usable floor space, and is situated on eight acres of
land.  The Company's executive and administrative offices are also located in
Buena, New Jersey in a 10,000 square foot building situated on six acres of
land.  In 1995, the Company completed and began operating a 25,000 square foot
production, product development, marketing, manufacturing and warehousing
facility for cosmetic, dermatologic and personal care products on this site.

  Each of the properties owned by the Company is subject to a mortgage held by
Fleet Bank-NH of Nashua, New Hampshire and Mellon Bank.  Except as discussed
above, the Company believes that its current production and office facilities
are adequate for its present and foreseeable future needs.

                                                                              12

*  In March 1994, IGI's Board of Directors voted to dispose of its Biotechnology
Business segment through the combination of certain majority-owned subsidiaries
and the subsequent tax-free Distribution of its ownership of the combined entity
to IGI's shareholders.  The distribution of this segment occurred on December
12, 1995.  The Consolidated Financial Statements of IGI present this segment as
a discontinued operation.  (See Note 2 of Notes to Consolidated Financial
Statements.)

                                                                              16

Item 7.  Management's Discussion and Analysis of Financial Condition and Results
of Operations

Results of Operations
- ---------------------

   On December 12, 1995, in order to facilitate obtaining capital for its
Biotechnology Business operations and continued expansion of its Animal Health
Products and Cosmetics and Consumer Products segments, IGI distributed its
ownership of Novavax, to IGI's shareholders ("Distribution").  Since the
operations of Novavax comprise IGI's Biotechnology Business segment, the
Consolidated Financial Statements of IGI present this segment as a discontinued
operation.  (See Note 2 of Notes to Consolidated Financial Statements).

  IGI's management believes that IGI's stockholders' interests were best served
by dividing IGI into two separate publicly-traded entities through the
Distribution; that the Distribution will enable IGI to focus on its historically
profitable and growing Animal Health Products business (Vineland Laboratories,
EVSCO Pharmaceuticals, and Tomlyn Products) as well as its Cosmetics and
Consumer Products which will continue to manufacture and market Novavax
technology based products under a license agreement; and that the Distribution
will simplify IGI and permit investors to more readily evaluate the earnings and
growth potentials of its businesses.

  Income from continuing operations decreased by $461,000 or 23% compared to
1994.  Operating profit decreased by $264,000 or 8% over 1994.  The Animal
Health Products segment generated operating profits in 1995 of $6,459,000, an
increase of $403,000, or 7%, over 1994 due to the increased sales volume.  The
Cosmetic and Consumer Products segment had an operating loss of $159,000 in
1995, compared to operating profits of $296,000 and $367,000 for 1994 and 1993,
respectively.  The 1995 operating loss reflects the Company's development and
marketing of Novavax Technologies products for dermatologic and food
applications while continuing to market these technologies to major cosmetic and
consumer product companies.  The operating loss for this segment in 1995
includes manufacturing variances related to the new production facility which
was not operating at full capacity and selling, marketing and development costs
for the Company's Nova Skin Care division.  The operating profits of these
segments do not reflect unallocated corporate expenses of $3,056,000, $2,845,000
and $3,000,000 for the years ended December 31, 1995, 1994, and 1993
respectively, which were charged to the segments in determining the Company's
operating profit.  (See Note 15 of Notes to Consolidated Financial Statements.)

  The loss from discontinued operations in 1995 resulted from increased
operating expenses related primarily to research efforts directed toward the
development of human vaccines and pharmaceuticals utilizing the Novavax
Technologies as well as transaction costs associated with the Distribution.  The
Company had anticipated the effective date of the Distribution to be June 30,
1995.  Due to delays in the final distribution of Novavax, the Company incurred
costs in excess of the $1,000,000 estimated loss on disposal of its
biotechnology business segment.  These costs related to increased research and
development expenses for products in the initial FDA approval process.  The
Biotechnology Business segment had no revenue from product sales in 1995, 1994
or 1993.  (See Note 2 of Notes to Consolidated Financial Statements.)

                                                                              17
<PAGE>
 
1995 Compared to 1994
- ---------------------

  Sales increased $2,273,000 or 8% to $31,221,000.  The growth was principally
attributable to increases in poultry vaccine sales, both domestically and
internationally.  Poultry vaccine sales accounted for $18,797,000 or 60% of the
Company's sales.  International and domestic poultry vaccine sales experienced
growth rates of 14% and 7% respectively.  The domestic increase was attributable
to the introduction of a new Rispen poultry vaccine during the second half of
1995.  The Company expects the sales of this product to continue to increase
during 1996.  The international poultry sales increase relates directly to the
increased product registration activities, particularly in the Asia/Pacific
marketplace which experienced a 24% sales increase.  Companion pet product sales
increased $225,000 or 2% to $10,713,000, although international sales of these
products declined particularly in Europe. Tomlyn sales, which are directed to
the over-the-counter marketplace, experienced a 28% increase, due principally to
the placement of these products in pet superstores.  Increased sales to Estee
Lauder contributed to a $234,000 or 16% growth in the Cosmetics division.  The
Company expects to increase the number of products that it manufactures for
Estee Lauder during 1996 as well as complete licensing arrangements with two
other cosmetic and consumer product companies.  In February 1996, the Company
launched a line of Novasome based alpha hydroxy acid ("AHA") products through
its Nova Skin Care division.  The Company is marketing these products directly
to dermatologists through a sales force of 16 employees.

  The Company's gross profit increased $776,000 or 5%, with much of the increase
related to sales growth.  As a percentage of sales, gross profit dropped from
52% during 1994 to 51% in 1995.  Significant factors in the gross profit ratio
reduction were increased sales of certain lower-margin poultry vaccines, fixed
costs associated with the Company's new manufacturing facility which was
operating below full capacity and the discontinuance of certain product lines.
As the production requirements for the Cosmetic and Consumer Products segment
increases during 1996, the Company expects an improvement in its gross profit
percentage.

  Selling, general and administrative expenses increased $1,256,000 or 12% due
in part to variable costs associated with the higher sales volume and additional
reserves established for international accounts receivables.  Selling and
marketing costs relating to the Company's new Nova Skin Care division were
$250,000.  The Company expects significant increases in selling and marketing
expenses in 1996 related to the Nova Skin Care product line.  These costs
include introductory advertising, sampling and tradeshows as well as sales and
marketing management.  Research and development expenses increased by $132,000
or 11% due to stepped up development in the Cosmetic and Consumer Products
segment, principally for the Nova Skin Care dermatologic product line.  The
Company intends to continue to increase its research and development efforts in
all of its businesses, with particular emphasis on developing new poultry
vaccines and developing additional products for the Nova Skin Care division.
During 1995, the Company recognized $731,000 in research revenues, an increase
of $348,000 or 91% over 1994.

  Interest expense increased $233,000 or 23% due to the higher borrowings
required to meet the operational demands of the biotechnology business segment.
The Company expects interest expense to increase during 1996 related to
borrowings that were required in December 1995 to fund the $5,000,000 license
payment to its former subsidiary, Novavax.

                                                                              18
<PAGE>
 
  The provision for income taxes on continuing operations was lower than the
statutory rate due principally to utilization of research and development tax
credits as well as an adjustment to prior years accruals.  (See Notes 1, 2 and 7
of Notes to Consolidated Financial Statements.)

1994 Compared to 1993
- ---------------------

  Net sales increased by $943,000 or 3% compared to 1993.  International sales
of poultry vaccines (Vineland Laboratories) and small animal products (EVSCO and
Tomlyn) increased by $1,077,000 or 11% and accounted for $11,360,000 or 39% of
the Company's sales, up from $10,282,000 or 37% of the Company's 1993 sales.
Domestic sales of EVSCO and Tomlyn products increased by $97,000 or 1%.
Domestic sales by Vineland Laboratories in 1994 were $330,000 or 4% less than in
1993.  This decrease was due to a combination of factors, including poultry
vaccine production capacity limitations which resulted in shipping of certain
vaccines to overseas rather than domestic markets, and domestic price erosion on
several vaccines.  Overall, sales of the Company's Animal Health Products
segment increased by $845,000 or 3% and accounted for $27,471,000 or 95% of the
Company's sales, compared to $26,627,000 or 95% of the Company's 1993 sales.
Sales of the Company's Cosmetics and Consumer Products segment were $1,477,000,
an increase of $98,000 over 1993.  These sales were principally of cosmetic
products utilizing the Novavax Technologies.

  Gross profit increased by $173,000 or 1% compared to 1993.  This increase was
attributable principally to the higher sales volume.  As a percentage of sales,
gross profit was 52%, down from 53% in 1993, due in part to domestic poultry
vaccine price concessions as a result of competitive pricing pressures.  In the
aggregate, gross profit margins from international sales were comparable to
those of domestic sales.

  Selling, general and administrative expenses increased by $38,000 due in part
to variable expenses associated with the higher sales volume.  As a percentage
of sales, the expenses decreased to 37% from 38% in 1993.  This decrease is
attributable to absorption of fixed costs by the higher sales volume.

  Gross research and development expenses increased $396,000 or 48% due
principally to additional technology application efforts focused at the
Company's core business operations, especially in the areas of flavors,
cosmetics and chemicals.  These expenditures were offset, in part, by research
revenues from industry partners of $383,000.

  Interest expense increased by $270,000 or 35% due principally to higher bank
borrowings at higher interest rates.  The additional borrowings were required
principally to fund the operations of the Company's discontinued Biotechnology
Business segment.

  The provision for income taxes on continuing operations was lower than the
statutory rate, due principally to a reduction in valuation allowances as well
as utilization of research and development tax credits.  The loss from
discontinued operations reflects an expected tax benefit of $797,000.  The
Company has recorded a full valuation allowance of $2,880,000 against the net
deferred tax asset from discontinued operations based on a determination of the
ultimate realizability of future deferred tax assets.  (See Notes 1, 2 and 7 of
Notes to Consolidated Financial Statements.)

                                                                              19
<PAGE>
 
  The loss from discontinued operations in 1994 consisted of $700,000 in
expenses incurred in excess of the $2,750,000 reserve established at December
31, 1993.  The Company's anticipated effective date for the Distribution of
September 30, 1994 was delayed principally by the late receipt of a favorable
tax-free ruling from the IRS.  The Company received the requested ruling from
the IRS in March 1995 and had originally intended to complete the Distribution
by June 30, 1995.  In addition to the aforementioned charges, the Company
established a reserve of $1,000,000 for additional operating and transaction
expenses to be incurred prior to the then anticipated effective date of the
Distribution.  (See Note 2 of Notes to Consolidated Financial Statements.)

Liquidity and Capital Resources
- -------------------------------

  On March 17, 1994, IGI's Board of Directors voted to dispose of the
biotechnology business segment through the combination of its majority-owned
subsidiaries Molecular Packaging Systems, Inc. ("MPS") and Novavax, Inc. and the
subsequent tax-free Distribution to IGI's shareholders.  On March 20, 1995, the
Company received a favorable ruling from the IRS that the Distribution would be
tax-free to IGI and its shareholders and the Company ultimately disposed of this
segment on December 12, 1995.  For the year ended December 31, 1995, the Company
incurred $5,034,000 in losses related to its biotechnology business segment of
which $1,000,000 were reserved for at December 31, 1994.  Since the operations
of Novavax comprised IGI's biotechnology business segment, the Consolidated
Financial Statements of IGI for the year ended December 31, 1995 report the
results of the biotechnology business segment as discontinued operations.  The
Company had anticipated the effective date of the Distribution to be June 30,
1995.  Due to delays in the final distribution of Novavax, the Company incurred
costs in excess of the $1,000,000 estimated loss on disposal of its
biotechnology business segment.  These costs related to increased research and
development expenses for products in the initial FDA approval process.  The
Distribution became effective December 12, 1995.

  Under the terms of the Distribution, the Company paid Novavax $5 million for a
fully paid-up license to use the Novavax Technologies in its business and
converted $17,024,000 of loans made to this operation in exchange for additional
shares of Novavax Stock, which was distributed to IGI shareholders in the
Distribution.  IGI had loaned $17,591,000 to Novavax to fund Novavax operations
through the Distribution Date.  Any advances made by IGI in excess of
$17,024,000 up to $250,000 have been deducted from the $5,000,000 payment under
the License Agreement.

  IGI funded the $5,000,000 payment to Novavax from borrowings under its bank
loan agreement which has been amended to reflect the Distribution.  The Amended
Loan Agreement with Fleet Bank - New Hampshire and Mellon Bank provides for:

 . $12,000,000 revolving credit facility with interest contingent upon certain
  financial ratios at the end of each quarter.  Effective January 1, 1996, the
  interest rate shall not exceed prime plus 1 1/2%.  The amount available under
  the revolving credit facility decreases by $800,000 on the last day of each
  quarter from June 30, 1996 through December 31, 1999.  At December 31, 1995
  the Company had outstanding borrowings of $12,000,000 under this facility and
  the interest rate was 9%.

                                                                              20
<PAGE>
 
 . $10,000,000 working capital line of credit renewable annually, with
  interest on the outstanding borrowings contingent upon certain financial
  ratios at the end of each quarter.  Effective January 1, 1996, the interest
  rate shall not exceed prime plus 1%.  At December 31, 1995 the Company had
  $1,952,000 available under this facility and the interest rate was 9.5%.

  The Company was in default of its current ratio covenant as of December 31,
1995.  The banks have amended the agreement to remove the default.

  The Company used $2,710,000 for operating activities due principally to
increases in inventories, related primarily to new products being introduced
during 1995, and accounts receivable related to the increase in international
sales.  Accounts receivable turnover ratio was 3.89 compared to 4.08 for the
year ended December 31, 1994.  Accounts receivable balances due from Mexico and
Latin America were 13% of the total receivable balance and the Company believes
the net amounts are fully collectible.  Mexico and certain Latin American
countries are important markets for the Company's poultry vaccines and other
products.  These countries have historically experienced varying degrees of
political unrest and economic and currency instability.  Because of the volume
of business transacted by the Company in those countries, continuation or the
recurrence of such unrest or instability could adversely affect the businesses
of its customers in those countries or the Company's ability to collect its
receivables from such customers, which in either case could adversely impact the
Company's future operating results.  The growth in inventories relates
principally to new animal health products that the Company began selling during
the third quarter as well as products for the Nova Skin Care division which were
launched in February 1996.  The inventory turnover ratio for 1995 was 1.81,
compared to 1.66 for the year ended December 31, 1994.  The Company believes its
reserves for inventory obsolescence and accounts receivable are adequate.  The
Company used $2,397,000 in investing activities for capital expenditures to
build and equip its new 25,000 square foot research, marketing and production
facility in Buena, New Jersey, as well as an additional $5,360,000 for the
payment of the License Agreement, patent costs and capital expenditures (See
Note 2 of Notes to Consolidated Financial Statements). Funding for the Company's
operating and investing activities were provided by borrowings under the
Company's working capital line of credit and the revolving credit facility. The
Company has no further obligation or intention to fund Novavax.

  At March 22, 1996 the Company had $1,485,000 of available borrowing capacity
under the working capital line of credit and no borrowings available under the
revolving line of credit. Funds generated from operations and existing bank
credit facilities are expected to be sufficient to meet the Company's short-term
cash requirements.  The Company has current maturities of long-term debt of
$800,000 per quarter commencing June 30, 1996.  The Company believes that cash
generated from operating activities as well as available borrowings under its
line of credit facility will be sufficient to meet these obligations.  However,
over the long-term, the Company will require additional funds to expand its
business.  No assurance can be given that the Company will be successful in
obtaining the required funds, and, if not, the Company may be required to cut
back on its expansion plans or otherwise appropriately modify its business
strategy.

                                                                              21
<PAGE>
 
Factors That May Affect Future Results

  The industry segments in which the Company competes are constantly changing
and are subject to significant competitive pressures.  The following sets forth
some of the risks which the Company faces.

     Availability of Capital

  The Company has historically applied the operating profits from its animal
health business to fund the development of its cosmetics business and its former
biotechnology business, Novavax, Inc., which was distributed to the Compay's
stockholders in December 1995.  Therefore, the Company is currently highly
leveraged and will need additional capital to finance the expansion of its
aniimal health and cosmetics and consumer products businesses.  No assurance can
be given that such funds will be obtained when required or, if obtainable, on
terms that are favorable to the Company.  In addition, the Company expects that
is interest expense will increase in 1996 as a result of increased borrowings,
which will impact the Company's profitability.

     Intense Competition in Cosmetic and Consumer Products Business

  The Company's Cosmetics and Consumer Products Division competes with large,
well-financed cosmetics and consumer products companies with developpment and
marketing groups that are expeprienced in the industry and possess far greater
resources than those available to the Company.  The Company expects to rely
principally on increased sales of its cometics and consumer products can compete
successfully against its competitors or that it can develop and market new
products that will be favorably received in the marketplace.  In addition,
certain of the Company's customers that use the Company's Novasomes in their
products may decide to reduce their purchases from the Company or shift their
business to other suppliers.

     Price Competition in Poultry Vaccine Business

  The Company is encountering increasing severe competition from international
producers of poultry vaccines, particularly increased price copetition coupled
with a downward trend in vaccine prices.  In addition, the Company's business
may be adversely affected by foreign import restrictions and additional
regulatory requirements.  Also, unstable or adverse economic conditions and
fiscal and monetary policies in certain Central and South American countries,
and increasingly important market for the Company's animal health products,
could adversely affect the Company's future business in these countries.

       Rapidly Changing Marketplace for Animal Health Products

  The emergence of pet superstores, the consolidation of distribution channels
into a smaller number of large, more powerful comppanies and the diminishing
traditional role of veterinarians in the animal health business may adversely
affect the Company's ability to expand its animal health business and to operate
this business at the gross margin  levels historically enjoyed by the Company.

                                                                              22
<PAGE>
 
     Effect of Rapidly Changing Technologies

  The Company expects to rely on the features of its Novavax Technologies to
market and expand its line of internally-developed dermatologic products.
However, if its competitors develop new and improved technologies that are
superior to the Company's technologies, the Company's products could be less
acceptable in the marketplace and therefore the Company's planned expansion of
its line of personal care and dermatologic products could be adversely affected.

     Regulatory Considerations

  The FDA may determine that the Company's alpha hydroxy acid-based products are
"drugs" and therefore should be subject to the expensive and sometimes
protracted FDA regulatory approval.  Also, certain of the Company's products may
not be approved for sales overseas on a timely basis, thereby limiting the
Company's ability to expand its foreign sales.

Accounting Standards Changes
- ----------------------------

  In March 1995, the Financial Accounting Standards Board ("FASB") issued
Statement of Financial Accounting Standards ("SFAS") No. 121, "Accounting for
the Impairment of Long-Lived Assets and for Long-Lived Assets to be Disposed
Of."  SFAS No. 121 requires companies to adopt its provisions for fiscal years
beginning after December 15, 1995.  This standard specifies when assets should
be reviewed for impairment, how to determine if an asset is impaired, how to
measure an impairment loss, and what disclosures are necessary in the financial
statements.  Management believes the impact of this pronouncement is not
material since the majority of the Company's long-lived assets are property,
plant and equipment that are utilized in the manufacturing of the Company's
products.

  In October 1995, the FASB issued SFAS No. 123, "Accounting for Stock-Based
Compensation."  SFAS No. 123 requires companies to adopt its provisions for
fiscal years beginning after December 15, 1995.  SFAS No. 123 encourages a fair
value based method of accounting for employee stock options or similar equity
instruments, but allows continued use of the intrinsic value based method of
accounting prescribed by Accounting Principles Board (APB) Opinion No. 25
"Accounting for Stock Issued to Employees."  Companies electing to continue to
use APB No. 25 must make pro forma disclosures of net income and earnings per
share as if the fair value based method of accounting had been applied.  The
Company is evaluating the provisions of SFAS No. 123, but has not yet determined
whether it will continue to follow the provisions of APB No. 25 or change to the
fair value method of SFAS No. 123.

Income Taxes
- ------------

  The Company has a net deferred tax asset in the amount of $2.9 million as of
December 31, 1995.  The largest deferred tax assets relate to the $5,000,000
license payment which will be deducted over the ten-year period as the related
products are sold and the royalties incurred and to net operating loss
carryforwards.  Management believes that the Company's deferred tax asset will
be realized through the reversal of existing temporary differences and the
utilization of net operating loss carryforwards and the prepaid license against
future taxable income.  The minimum level of future taxable income necessary to
realize the Company's recorded deferred tax asset at 

                                                                              23
<PAGE>
 
December 31, 1995, is approximately $        million.  The net operating loss 
carryforwards expire in 2010 and there are no limitations on their use.
Management believes that it will be able to utilize these carryforwards. The
Company's consolidated federal taxable income (loss) varies from its
consolidated financial statement income (loss). In 1993 and 1994, taxable income
was higher due to the establishment of reserves for losses on discontinued
operations; in 1995, taxable income was lower as the reserves were utilized.

                       REPORT OF INDEPENDENT ACCOUNTANTS


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

     We have audited the consolidated financial statements and financial
statement schedule of IGI, Inc. and subsidiaries as listed in Item 14(a) of this
Form 10-K. These financial statements and financial statement schedule are the
responsibility of the Company's management. Our responsibility is to express an
opinion on these financial statements and financial statement schedule based on
our audits.

     We conducted our audits in accordance with generally accepted auditing
standards.  These 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 the disclosures in the financial statements.  An audit also
includes assessing the accounting principles used and significant estimates made
by management, as well as evaluating the overall financial statement
presentation.  We believe that our audits provide a reasonable basis for our
opinion.

     In our opinion, the financial statements referred to above present fairly,
in all material respects, the consolidated financial position of IGI, Inc. and
its subsidiaries at December 31, 1995 and 1994 and the consolidated results of
their operations and their cash flows for each of the three years in the period
ended December 31, 1995 in conformity with generally accepted accounting
principles. In addition, in our opinion, the financial statement schedule
referred to above, when considered in relation to the basic financial statements
taken as a whole, presents fairly, in all material respects, the information
required to be included therein.

 1.  Summary of Significant Accounting Policies
     ------------------------------------------

 
Nature of the Business
- ----------------------

IGI, Inc. ("IGI or the "Company") is a diversified company engaged in two
business segments.  The Animal Health Products Business produces and markets
animal health products such as poultry vaccines, veterinary products,
nutritional supplements and grooming aids.  The Cosmetics and Consumer Products
Business produces and markets cosmetic and consumer products such as skin care
products and shampoos.

Principles of Consolidation
- ---------------------------

The consolidated financial statements include the accounts of IGI, Inc. and its
wholly-owned and majority-owned subsidiaries.  The Company's financial
statements include 100% of the losses through December 12, 1995 of its formerly
majority-owned subsidiaries which include Molecular Packaging Systems, ("MPS")
and Novavax, Inc.  All intercompany accounts and transactions have been
eliminated.

Cash equivalents
- ----------------

Cash equivalents consist of short term investments with initial maturities of 90
days or less.

Inventories
- -----------

Inventories are stated at the lower of cost (last-in, first-out basis)
or market.

Property, Plant and Equipment
- -----------------------------

Depreciation of property, plant and equipment is provided for under the
straight-line method over the estimated useful lives as follows:

                                              Useful Lives
                                              ------------
Buildings and improvements                     10-30 years
Machinery and equipment                         3-10 years

Repair and maintenance costs are charged to operations as incurred while major
improvements are capitalized.  When assets are retired or disposed of, the cost
and accumulated depreciation thereon are removed from the accounts and any gains
or losses are included in operations.

Amortization
- ------------

Cost in excess of net assets of businesses acquired, which is included in other
assets, is amortized on a straight-line basis over 40 years.
The Company periodically evaluates the carrying amount of this asset using cash
flow projections and net income and if warranted, impairment would be
recognized.

   1.  Summary of Significant Accounting Policies (continued)
       ------------------------------------------            


Income Taxes (continued)
- ------------            

The Company records income taxes under the provisions of Statement of Financial
Accounting Standards ("SFAS") No. 109, "Accounting for Income Taxes".  SFAS 109
requires the asset and liability method of accounting for income taxes.  Under
the asset and liability method, deferred income taxes are recognized for the tax
consequences of "temporary differences" by applying enacted statutory tax rates
applicable to future years to differences between the financial statement
carrying amounts and the tax bases of existing assets and liabilities.  Under
SFAS No. 109, the effect on deferred taxes of a change in tax rates is
recognized in income in the period that includes the enactment date.  A
valuation allowance is recorded based on a determination of the ultimate
realizability of future deferred tax assets.

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.
Significant estimates include allowances for excess and obsolete inventories,
allowances for doubtful accounts and other assets and provisions for income
taxes and related valuation allowances.  Actual results could differ from those
estimates.

Financial Instruments
- ---------------------

The Company's financial instruments include cash and cash equivalents, accounts
receivable, notes receivable and long-term debt.  The carrying value of these
instruments approximates the fair value.

Accounting Standards Changes
- ----------------------------

In March 1995, the Financial Accounting Standards Board ("FASB") issued SFAS No.
121, "Accounting for the Impairment of Long-Lived Assets and for Long-Lived
Assets to Be Disposed Of." SFAS No. 121 requires companies to adopt its
provisions for fiscal years beginning after December 15, 1995. This standard
specifies when assets should be reviewed for impairment, how to determine if an
asset is impaired, how to measure an impairment loss, and what disclosures are
necessary in the financial statements. Management believes the impact of this
pronouncement is not material since the majority of the Company's long-lived
assets are property, plant and equipment that are utilized in the manufacturing
of the Company's products.

 1. Summary of Significant Accounting Policies (continued)
    ------------------------------------------            


 Accounting Standards Changes (continued)
 ----------------------------            

 In October 1995, the FASB issued SFAS No. 123, "Accounting for Stock-Based
 Compensation."  SFAS No. 123 requires companies to adopt its provisions for
 fiscal years beginning after December 15, 1995.  SFAS No. 123 encourages a fair
 value based method of accounting for employee stock options or similar equity
 instruments, but allows continued use of the intrinsic value based method of
 accounting prescribed by Accounting Principles Board ("APB") Opinion No. 25
 "Accounting for Stock Issued to Employees."  Companies electing to continue to
 use APB No. 25 must make pro forma disclosures of net income and earnings per
 share as if the fair value based method of accounting had been applied.  The
 Company is evaluating the provisions of SFAS No. 123, but has not yet
 determined whether it will continue to follow the provisions of APB No. 25 or
 change to the fair value method of SFAS No. 123.

 Revenue Recognition
 -------------------

 Revenues earned under research contracts are recognized when the related
 contract provisions are met.

 Reclassification
 ----------------

 Certain previously reported amounts have been reclassified to conform with the
 current period presentation.


 2. Corporate Activities
    --------------------


 Distribution of Biotechnology Segment
 -------------------------------------

 On March 17, 1994, IGI's Board of Directors voted to dispose of the
 biotechnology business segment through the combination of its majority-owned
 subsidiaries Molecular Packaging Systems, Inc. and Novavax, Inc. and the
 subsequent tax-free Distribution to IGI's shareholders of its ownership of the
 combined entity.

 On December 12, 1995 (the "Distribution Date"), IGI distributed to the holders
 of record of IGI's common stock, at the close of business on the Record Date,
 November 28, 1995, one share of common stock of Novavax, Inc. ("Novavax") for
 every one share of IGI common stock outstanding (the "Distribution").

 2. Corporate Activities (continued)
    --------------------            

Distribution of Biotechnology Segment (continued)
- -------------------------------------            

In connection with the Distribution, the Company has paid Novavax $5,000,000 in
return for a fully-paid-up, ten-year license entitling it to the exclusive use
of Novavax's technologies in the fields of (i) animal pharmaceuticals,
biologicals, and other animal health products; (ii) foods, food applications,
nutrients and flavorings; (iii) cosmetics, consumer products and dermatological
over-the-counter and prescription products (excluding certain topically
delivered hormones); (iv) fragrances; and (v) chemicals, including herbicides,
insecticides, pesticides, paints and coatings, photographic chemicals and other
specialty chemicals; and the processes for making the same.  The Company has the
option, exercisable within the last year of the ten-year term, to extend the
License Agreement for an additional ten-year period for $1,000,000.  Novavax
will retain the right to use its Novavax Technologies for all other
applications, including human vaccines and pharmaceuticals.  At the time the
terms of the IGI License Agreement were fixed, including the license payment,
all of the directors of IGI were also directors of Novavax and these terms were
unilaterally established by IGI.  As of December 31, 1995, three directors of
IGI were also directors of Novavax.  The Company has presented the payment under
the License Agreement as a capital contribution in its financial statements to
reflect the intercompany nature and substance of the transaction.  The form was
structured as a prepaid license agreement to address various considerations of
the Distribution, including tax and financing considerations.  For tax purposes,
the transaction will be treated as a prepaid license agreement.  IGI has no
further obligations or intentions to fund Novavax.

Components of the losses from discontinued operations for each of the three
years in the period ended December 31, 1995 were:

 *Includes $475,000 and $380,700 of initial payments in 1994 and 1993,
respectively on product development and licensing agreements or detailed
agreements in principle which have been reflected as a reduction in research and
development expenses.

The Company had anticipated the effective date of the Distribution to be June 
30, 1995. Due to delays in the final distribution of Novavax, the Company 
incurred costs in excess of the $1,000,000 estimated loss on disposal of its 
biotechnology business segment. These costs related to increased research and 
development expenses for products in the initial FDA approval process.

The credit for income taxes does not equal the statutory rate because of
valuation allowances related to loss carryforwards.

2.  Corporate Activities (continued)
    --------------------            


Equity and Other Transactions
- -----------------------------

In August 1993, the Company entered into an agreement with an industry partner
for the testing of Novavax's patented Novasome lipid vesicle encapsulation
technology as a microcarrier and adjuvant for various human vaccines. The
Company received $1,000,000 in exchange for 99,700 shares of the Company's
common stock. In addition, the Company received $100,000 from this partner to
offset research expenses. The $100,000 is included in the loss from discontinued
operations in 1993. In December 1994, the partner exercised its option to enter
into an exclusive license agreement by agreeing to pay the Company $475,000 for
the use of the technology in certain applications and additional research
funding. This amount is included in the loss from discontinued operations in
1994. Additionally, the partner exercised its option to purchase shares of the
Company's common stock. In January 1995, the Company issued 226,655 shares of
its common stock for $2,500,000. This agreement was amended in December 1995 in
connection with the Distribution. Under the terms of the amended agreement, the
industry partner has the option to purchase up to approximately $6,800,000 of
IGI Common Stock and approximately $3,700,000 of Novavax Common Stock,
concurrently. These amounts were determined, pursuant to the agreement, by
calculating the average ratio of closing prices of IGI and Novavax common stock
for the first twenty days following the Distribution. The price per share for
Novavax's and IGI's common stock is to be determined on the date of exercise and
is capped at an aggregate combined price per share of $13.00.  This option will
expire in 1996.

 5. Long-Term Debt (continued)
    --------------            

A commitment fee of 1/2% is payable on the unused portion of the working
capital line and 1/4% on the unused revolving credit facility.  The agreement
requires the Company to maintain certain financial ratios, comply with other
covenants and restricts the payment of cash dividends to not more than 25% of
the net income in any one year and to retained earnings in excess of $1,000,000.

The Company was in default of its current ratio covenant as of December 31,
1995.  The banks have amended the agreement to remove the default.

Aggregate annual principal payments on long-term debt, for the five years
subsequent to December 31, 1995 and thereafter are as follows:


                        1996   $ 2,415,101

All of the Company's assets are pledged as collateral under the terms of the
loan agreement.  As of December 31, 1995, there were no outstanding equipment
leases.  At December 31, 1994, equipment under capital leases totaled $312,442,
less accumulated depreciation of $260,221.

 6. Stock Options
    -------------

Under the 1983 Incentive Stock Option Plan, options have been granted to key
employees to purchase a maximum of 500,000 shares of common stock.  Options,
having a maximum term of 10 years, have been granted at 100% of the fair market
value of the Company's stock at the time of grant.  Options outstanding under
this plan at December 31, 1995 are generally exercisable in cumulative

employees and directors to purchase a maximum of 500,000 and 1,900,000 shares of
common stock, respectively.  Options, having a maximum term of 10 years, have

of grant.  Both incentive stock options and non-qualified stock options may be
granted under the 1989 Plan and the 1991 Plan.  Incentive stock options are
generally exercisable in cumulative increments over four years commencing one
year from the date of grant.  Non-qualified options are generally exercisable in
full beginning six months after the date of grant.

In 1991, the Company's Board of Directors adopted a Non-Qualified Stock Option
Plan. The plan provides that options may be granted to consultants, scientific
advisors and employees to purchase a maximum of 250,000 shares of common stock.
Options outstanding under this plan at December 31, 1995 are generally
exercisable in cumulative increments over four years commencing one year from

In connection with the Distribution, holders of options to purchase IGI common
stock as of the Distribution Date were granted options to purchase Novavax
common stock and substitute options to purchase IGI common stock.  Exercise
prices of the options were based on the relative market capitalization of IGI
and Novavax on the record date and the 20 trading days immediately following the
record date to restore holders of each option to the economic position prior to
the Distribution Date.  The prices related to stock option transactions have
been adjusted to reflect the terms of the substitute options.

</TABLE>

In 1994, due to the imminent Distribution, the Company reevaluated the
recoverability of its deferred tax assets and as such, adjusted its valuation
allowance to reflect its new estimates.  Management has determined, based on the
Company's history of prior operating earnings and its expectations for the
future, that operating income of the Company will more likely than not be
sufficient to recognize fully these net deferred tax assets.

Operating loss and tax credit carryforwards available for tax reporting
purposes as December 31, 1995 are as follows:
    Federal:
    Operating losses (expiring in the year
       2010)                                             $ 3,993,391

 8. Net Income per Share:
    -------------------- 

Net income per share of Common Stock is computed by dividing net income by the
weighted average number of shares of Common Stock and Common Stock Equivalents,
if dilutive, outstanding during the year.  Common Stock Equivalents include
shares issuable upon the exercise of dilutive common stock options.  Fully
diluted earnings per share approximate primary earnings per share.

 9. Commitments and Contingencies:
    ----------------------------- 

The Company leases manufacturing and warehousing space, machinery and equipment
and automobiles under noncancellable operating lease agreements expiring at
various dates through 1997.  Rental expense aggregated approximately $ 281,501
in 1995, $185,962 in 1994, and $208,447 in 1993.  Future minimum rental
commitments under noncancellable operating leases as of December 31, 1995 are as
follows:

                              1996        77,152
                              1997        61,860
                              1998        49,043
                              1999        43,922
                              2000        38,154
 
The Company has entered into employment contracts with expiration dates through
December 31, 1999 with certain officers which provide that these officers are
entitled to continuation of their salaries if they are terminated without cause
prior to their contract expiration date.  Aggregate compensation through 1999
under these agreements approximates $3,206,580.

 10.  Litigation
      ----------

Certain claims, suits and complaints arising in the ordinary course of business
have been filed or are pending against the Company and its subsidiaries.  In the
opinion of management, after consultation with legal counsel, all such matters
are adequately covered by insurance or, if not so covered, are without merit or
are of such kind, or involve such amounts, as would not have a significant
effect on the financial position or results of operations of the Company if
disposed of unfavorably.

  On February 6, 1996, Johnson & Johnson and its wholly-owned subsidiary Ortho-
McNeil, Inc. (collectively, "J&J") filed a lawsuit against the Company and its
subsidiary, Igen, Inc. and its former subsidiary Micro-Pak, Inc. in the United
States District Court for the District of New Jersey alleging trademark
infringement and trademark dilution. J&J alleges that the Company's use of the
names NOVA SKIN, NOVA SKIN CARE, and NOVA-AESTHETICS infringes on rights
associated with J&J's trademark RENOVA for a prescription drug. J&J has also
moved for a preliminary injunction seeking to preclude the Company's use of the 
NOVA SKIN, NOVA SKIN CARE, and NOVA-AESTHETICS names on the Company's 
newly-launched line of skin care products sold through dermatologists. On March 
18, 1996, following a period of expedited discovery, the Court held an 
evidentiary hearing on the motion for preliminary injunction. The Court has not 
yet issued a ruling.

  Since 1988, the Company has used the trademark NOVASOME in connection with the
lipid vesicle encapsulation technology it developed, including in connection 
with skin care products. In addition, numerous other companies use the term 
NOCVA in a wide variety of product and corporate name formulations. The Company 
is vigorously defending this lawsuit and believes that the outcome of the 
proceedings will not have a material adverse effect on the Company's financial 
position or results of operations.

Related net accounts receivable balances at December 31, 1995, 1994  and 1993
approximated $4,921,253, $4,263,579 and $4,035,969, respectively.


 12.  Certain Relationships and Related Party Transactions:
      ---------------------------------------------------- 

In 1990, the Company loaned $70,000 to its president and in 1993 loaned a total
of $182,400 to four other officers.  The remaining balances of notes are
included in stockholders' notes receivable in the accompanying Consolidated
Balance Sheets.  In 1992, the Company loaned a total of $200,000 to two other
officers.  The remaining balances of these notes are included in notes
receivable, net of current maturities, in the accompanying Consolidated Balance
Sheets.  All of these loans are evidenced by demand notes bearing interest at
prime plus 1/4% and are collateralized by shares of common stock of either IGI
or one of its subsidiaries.  In 1989, the Company loaned $200,000 to the
president of MPS, which was repaid in 1995 with MPS stock.  During 1995, 1994,
and 1993, the Company recognized $38,566, $34,494 and $25,081, respectively, in
interest income from these notes.

 13.  Employee Benefits:
      ----------------- 

The Company has a defined contribution retirement plan (401(k)), pursuant to
which employees who have completed one year of employment with the Company or
its subsidiaries as of specified dates may elect to contribute to the Plan, in
whole percentages, up to 18% of compensation, subject to a minimum contribution
by participants of 2% of compensation and a maximum contribution of $9,240 in
1995 and 1994, and $8,994 in 1993.  The Company matches 25% of the first 5% of
compensation contributed by participants and contributes on behalf of each
participant $4 per week of employment during the year.  All contributions of the
Company are made quarterly in the form of the Company's Common Stock ($.01 par
value) and are immediately vested.  The Company has recorded charges to expense
related to this plan of approximately $103,601, $62,200, and $76,100 for the
years 1995, 1994, and 1993, respectively.

 14.  Concentration of Credit Risk:
      ---------------------------- 

Financial instruments which potentially subject the Company to concentration of
credit risk consist principally of cash and cash equivalents.  The company
places its cash and cash equivalents with two high credit quality financial
institutions.  Export receivables include customers in several key geographic
areas; of these, Mexico and other Latin American countries are important markets
for the Company's poultry vaccines and other products.  These countries have
historically experienced varying degrees of political unrest and economic and
currency instability.  Because of the volume of business transacted by the
Company in those countries, continuation or recurrence of such unrest or
instability could adversely affect the businesses of its customers in those
countries or the Company's ability to collect its receivables from such
customers, which in either case could adversely impact the Company's future
operating results.

          (b) Such revolving credit loans are herein sometimes referred to

Credit Advances".  Subject at all times to all of the terms and conditions of
this Agreement, from the date hereof to the Revolving Credit Termination Date
and within the limits of the Revolving Credit Commitment as in effect from time
to time, Fleet shall lend sixty (60%) percent and Mellon shall lend forty (40%)
percent of the aggregate amount of each Revolving Credit Advance and of all

otherwise provided in the Revolving Credit Notes) and reborrow in minimum

          (c) The Borrowers shall jointly and severally pay the Lenders interest
on all Revolving Credit Advances at the rate(s) per annum as in effect from time

jointly and severally pay to the Lenders, quarterly through the Revolving Credit

Borrowers jointly and severally hereby authorize the Lenders to charge the
Borrowers' revolving credit loan accounts for all such interest and Revolving
Credit Commitment Fees.  The Agent will report to IGI monthly as to the status
of such revolving credit loan accounts, and each such report shall be fully
binding on all Borrowers, except to the extent that IGI gives the Lenders
written notice of exceptions within thirty (30) days after its receipt of such
report.

          (d) In accordance with provisions set forth in the Security Agreement,
the Agent may, upon the occurrence and during the continuation of any Event of
Default: (i) notify the Borrowers' account debtors that all accounts and
receivables of the Borrowers have been assigned to the Agent, (ii) collect said
accounts and receivables directly, and (iii) charge all collection costs and
expenses directly to the Borrowers' revolving credit loan accounts.

          (e) Unless an Event of Default hereunder shall have occurred and shall
be continuing, or as otherwise provided in the Revolving Credit Notes, or as
otherwise required from time to time in order to reduce the outstanding
principal amount of Revolving Credit Advances to an amount not in excess of the
Revolving Credit Commitment then in effect, the Lenders shall not, prior to the
Revolving Credit Termination Date, terminate this revolving credit facility or
demand repayment of the principal of the Revolving Credit Notes.

Amended and Restated Revolving Credit Note of the Borrowers payable to the order
of Fleet in substantially the form annexed hereto as Exhibit "A-1", and a

Business Day next following the subject request, which notice shall be in
substantially the form of the Borrowing Request Certificate annexed as Exhibit
"J" to the Original Agreement.

          (b) The Borrowers shall jointly and severally pay the Lenders interest
on all Line of Credit Advances at the rate(s) per annum as in effect from time
to time in accordance with the Line of Credit Notes.  Such interest shall be
payable monthly in arrears,

                                      -18-
<PAGE>
 
and shall be computed on the daily unpaid balance of all Line of Credit Advances
made under the Borrowers' revolving credit loan accounts with the Lenders, based
on a three hundred sixty (360) day year, counting the actual number of days
elapsed.  In addition, the Borrowers shall jointly and severally pay to the
Lenders, quarterly through the Line of Credit Termination Date, in arrears, a
fee (the "Line of Credit Commitment Fee") computed by multiplying (i) one-half
of one (1/2%) percent, times (ii) the actual number of days in the subject
quarterly period, times (iii) the difference of (x) $10,000,000 minus (y) the
                                                                -----        
average daily principal amount of all outstanding Line of Credit Advances to the
Borrowers during such quarterly period, and then dividing such product by three
hundred sixty (360).  The Borrowers jointly and severally hereby authorize the
Lenders to charge the Borrowers' line of credit loan accounts for all such
interest and Line of Credit Commitment Fees.  The Agent will report to IGI
monthly as to the status of such line of credit loan accounts, and each such
report shall be fully binding on all Borrowers, except to the extent that IGI
gives the Lenders written notice of exceptions within thirty (30) days after its
receipt of such report.

          (c) In accordance with provisions set forth in the Security Agreement,
the Agent may, upon the occurrence and during the continuation of any Event of
Default: (i) notify the Borrowers' account debtors that all accounts and
receivables of the Borrowers have been assigned to the Agent, (ii) collect said
accounts and receivables directly, and (iii) charge all collection costs and
expenses directly to the Borrowers' line of credit loan accounts.

          (d) All Line of Credit Advances shall be repayable to the Lender ON
DEMAND; provided, that the Lenders shall not, prior to the Line of Credit
Termination Date, terminate this line of credit facility or demand repayment of
the Line of Credit Notes, except upon the occurrence of an Event of Default (as
hereinafter defined) or as otherwise provided in this Agreement or in any of the
Notes.

          (e) The availability of the line of credit facility may be extended on
the same terms and conditions on an annual basis beyond the Line of Credit
Termination Date in the sole discretion of the Lenders (by unanimous affirmative
agreement thereof) by written notice from the Lenders to the Borrowers.
Extensions on other than an annual basis shall be upon such terms and conditions
as the Lenders (by unanimous affirmative agreement thereof) and the Borrowers
shall mutually agree upon in writing.  For purposes of this Agreement, the term
"Line of Credit Termination Date" shall also mean and include any date or dates
to which the Line of Credit Commitment is so extended.

          (f) All Line of Credit Advances heretofore and hereafter made by the
Lenders pursuant to this Section 2.02 shall be evidenced by a secured Second
Amended and Restated Line of Credit

                                      -19-

Note of the Borrowers payable to the order of Fleet in substantially the form
annexed hereto as Exhibit "B-1", and a secured Second Amended and Restated Line
of Credit Note of the Borrowers payable to the order of Mellon in substantially
the form annexed hereto as Exhibit "B-2", which Line of Credit Notes are hereby
incorporated herein by this reference and made a part hereof.

     Section 2.02A.  Calculation of Certain Fees.  Anything contained in
     -------------------------------------------                        
Sections 2.01 and 2.02 above to the contrary notwithstanding, the Revolving
Credit Commitment Fee and the Line of Credit Commitment Fee for the quarter
ending December 31, 1995 shall be calculated (a) for that portion of the
calendar quarter to the date hereof, based on the provisions of the Amended and
Restated Loan Agreement, and (b) for that portion of the calendar quarter from
and after the date hereof, based on the provisions of this Agreement.

     Section 2.03  Letters of Credit; Banker's Acceptances.
     ----------------------------------------------------- 

          (a) Subject at all times to all of the terms and conditions of this
Agreement, Fleet may, in its sole discretion, from time to time from the
Agreement Date to the Line of Credit Termination Date, for the account of any of
the Borrowers, on terms and conditions satisfactory to Fleet, at the request of
any of the Borrowers, provide one or more of the following financial
accommodations to such Borrower:  (i) issue or cause to be issued one or more
standby letters of credit or other such instruments in support of the
performance by such Borrower of its written obligations to the beneficiaries of
such standby letters of credit or other instruments; (ii) issue or cause to be
issued one or more letters of credit or other such instruments respecting the
purchase of inventory in the normal course of the Business Operations, for the
benefit or account of such Borrower, and all having an expiration date at least
twenty (20) Business Days prior to the Line of Credit Termination Date, and/or
(iii) issue or cause to be issued banker's acceptances or other such instruments
indemnifying the issuer of, or guarantying performance by the subject Borrower
in connection with, letters of credit issued for the benefit or account of such
Borrower for the purchase of inventory in the normal course of the Business
Operations (individually and collectively, the "L/C Accommodations"), all on
such terms and in such form as Fleet may elect or determine.

          (b) Without limiting Fleet's continuing discretion as aforesaid, the
extension of such L/C Accommodations by Fleet shall in each instance and at all
times be subject to the satisfaction of each of the following additional
conditions precedent:  (i) the Borrowers shall have additional unused borrowing
capacity, within the Line of Credit Commitment, equal to or in excess of the
face amount of each requested L/C Accommodation at the time of the request
therefor;  (ii) except in the case of standby letters of

                                      -20-
<PAGE>
 
credit, the Agent shall have a valid and perfected first lien and security
interest in all form of interest of the Borrower in the inventory to be acquired
under such L/C Accommodation; (iii) the form and content of all such L/C
Accommodations and related documents shall be satisfactory to Fleet, and all
documents, instruments, notices and statements relating thereto (including,
without limitation, any assignments of underlying purchase orders, shipping
documents and/or letters of credit), if any, which Fleet may deem necessary to
give effect to and protect the Agent's liens and security interests (to the
extent applicable) and other rights, shall be promptly delivered to the Agent;
and (iv) the Borrowers shall have fully complied with all terms and provisions
hereof relative to the L/C Accommodations, including the payment of all fees and
charges set forth herein.

          (c)  The full face amount of all outstanding L/C Accommodations shall
be applied against the Line of Credit Commitment, shall (for purposes of
computing borrowing capacity within the Line of Credit Commitment) be deemed to
constitute outstanding Line of Credit Advances, and shall otherwise be subject
to the terms and conditions of this Agreement (including, without limitation,
the imposition of interest charges on any amounts actually paid by Fleet under
any L/C Accommodations); and any amounts actually paid by Fleet under any L/C
Accommodations shall be deemed Advances represented by the Line of Credit Note.

          (d)  The Borrowers jointly and severally hereby agree to pay to Fleet
and/or any bank or issuer in connection with the L/C Accommodations the standard
fees and charges charged by Fleet or such bank or issuer in such amounts and at
such intervals as may be required by Fleet or such bank or issuer.  Any amounts
not paid to Fleet when due in respect of any L/C Accommodations may, at the
discretion of such Lender, be added to the Line of Credit Advances.

          (e)  Anything elsewhere contained in this Agreement to the contrary
notwithstanding, the aggregate outstanding face amount of all L/C Accommodations
made or incurred by Fleet for the account or benefit of the Borrowers shall not
at any one time exceed $100,000.

          (f)  All responsibility for all transactions underlying or related to
any L/C Accommodations (other than complying with and honoring Fleet's
obligations thereunder in accordance with the terms thereof) shall remain with
the Borrowers.  The Borrowers shall jointly and severally indemnify and hold
harmless Fleet with respect to any cost, claim, damage, loss, liability or
expense which Fleet may in any way suffer or incur in connection with or by
reason of any transaction underlying or relating to any L/C Accommodations.

          (g)  In the event that and at such time as the Line of Credit Advances
shall at any time become immediately due and

                                      -21-
<PAGE>
 
payable by reason of the occurrence of the Line of Credit Termination Date, or
by reason of any Borrower's having entered into any revolving credit
arrangements (or other comparable arrangements) other than pursuant to or as
permitted by this Agreement, or by reason of an Event of Default, then the
Borrowers shall, simultaneously therewith, either (i) make arrangements
satisfactory to Fleet for the return and cancellation of any and all then-
outstanding L/C Accommodations by the beneficiary or beneficiaries thereof, or
(ii) deposit with Fleet, on terms and conditions satisfactory to Fleet, cash
collateral in an amount equal to the aggregate face amount of all remaining
then-outstanding L/C Accommodations.

     Section 2.04.  Use of Proceeds.  The Borrowers shall utilize (a) the Line
     ------------------------------

Properties and related improvements thereon which may hereafter be owned,
constructed or acquired by any of the Borrowers (other than Immaterial Real

     Section 2.06.  Further Obligations.  With respect to all Obligations for
     ----------------------------------

the Revolving Credit Commitment, and shall bear interest at the floating rate
per annum applicable to Revolving Credit Advances.

     Section 2.07.  Prepayment of Notes.
     ---------------------------------- 

          (a) The Borrowers shall provide the Lenders with not less than five
(5) Business Days' prior written notice of the Borrowers' intention to prepay

fiscal quarter.

          (b) If and so long as no Event of Default has occurred and is

<PAGE>
 
notice to the Lenders, to designate whether any prepayment of any of the
Obligations (excluding, however, a required reduction in the amount of
outstanding Revolving Credit Advances in accordance with Section 2.01(a) hereof)
shall be applied against the Revolving Credit Notes or the Line of Credit Notes.
Any one or more prepayments of the Notes may be made without penalty or premium,
except as otherwise provided in the Notes.

     Section 2.08.  Set-Off of Bank Accounts.  In addition to the security and
     ---------------------------------------                                  
collateral set forth in or referred to in this Agreement, each of the Borrowers,
as further security for the Obligations, hereby jointly and severally pledges
and grants to the Lenders a Lien and security interest, in an aggregate amount
equal to all of the Obligations from time to time owed to the Lenders, in and to
the balances of any deposit accounts now or at any time hereafter maintained by
such Borrower with the Lenders.  If any Event of Default hereunder shall occur,

of and accrued interest on any of the Notes and other Obligations in such order
or priority as the Lenders, in their discretion, may determine, subject to the
provisions of Section 9.10 hereof.  The Borrowers hereby jointly and severally
covenant and agree to execute and to cause all other depositories to execute any
documents, as the Lenders may deem necessary, for the granting and perfection of
Lenders' security interests in such depository accounts.

     Section 2.09.  Obligations Unconditional.  The payment and performance of
     ----------------------------------------                                 
all Obligations shall constitute the absolute and unconditional obligations of
the Borrowers, and shall be independent of any defense or rights of set-off,
recoupment or counterclaim which any Borrower might otherwise have against
either of the Lenders.  All payments required by this Agreement and/or the Notes
or Security Documents shall be paid free of any deductions and without
abatement, diminution or set-off.

     Section 2.10.  Reversal of Payments.  To the extent that any payment or
     -----------------------------------                                    
payments made to or received by the Lenders or the Agent pursuant to this
Agreement, any of the Notes or any of the Security Documents are subsequently
invalidated, declared to be fraudulent or preferential, set aside, or required
to be repaid to any trustee, receiver or other person under any state or federal
bankruptcy or other such law, then, to the extent thereof, such amounts shall be
revived as Obligations and continue in full force and effect hereunder, as if
such payment or payments had not been received by the subject Lender or the
Agent.


III. REPRESENTATIONS AND WARRANTIES
     ------------------------------

     The Borrowers hereby jointly and severally make the following
representations and warranties to the Lenders, all of which

                                      -24-
<PAGE>
 
representations and warranties shall survive the Agreement Date, the delivery of
the Notes and the making of the Loans, and are as follows:

     Section 3.01.  Financial Matters.
     -------------------------------- 

          (a) The Borrowers have heretofore furnished to the Lenders audited
consolidated financial statements (including consolidated balance sheets,
consolidated statements of income and consolidated statements of cash flows) of
IGI and its consolidated Subsidiaries as at December 31, 1994, 1993, 1992, 1991
and 1990 and for each of the five (5) consecutive Fiscal Years ended on such
dates (the "Financial Statements").

          (b) The Financial Statements have been prepared in accordance with
GAAP on a consistent basis for all periods, are complete and correct in all
material respects, and fairly present the consolidated financial condition of
IGI and its consolidated Subsidiaries as at said dates, and the results of
operations for the periods stated.  The books of account and other financial
records of IGI and each of the Subsidiaries have been maintained in accordance
with GAAP, consistently applied.

          (c) The Borrowers have heretofore furnished to the Lenders the pro
forma consolidated balance sheet of the Borrowers as of September 30, 1995, but
giving pro forma effect to the Spin-Off and all required borrowings hereunder in
connection with the Spin-Off (the "Pro Forma Balance Sheet").  The Pro Forma
Balance Sheet fairly reflects the consolidated financial condition of IGI and
its consolidated Subsidiaries as of the date thereof and after giving pro forma
effect to the Spin-Off and all borrowings required in connection with the Spin-
Off, subject only to normal audit and year-end adjustments which are not and
will not be material.

          (d) Neither IGI nor any of the Subsidiaries has any Liabilities,
obligations or commitments of any kind or nature whatsoever, whether absolute,
accrued, contingent or otherwise (collectively "Liabilities and Contingencies"),
including, without limitation, Liabilities and Contingencies under employment
agreements and with respect to any "earn-outs", stock appreciation rights, or
related compensation obligations, except: (i) Liabilities and Contingencies
disclosed in the Financial Statements or footnotes thereto, or in the Pro Forma
Balance Sheet, (ii) Liabilities and Contingencies not incurred in the ordinary
course of the Business Operations, all of which (and the amounts thereof, to the
extent determinable) are disclosed on Schedules to this Agreement (to the extent
required to be so disclosed hereunder) or in public filings made with the SEC
under the Securities Exchange Act of 1934, as amended (true and complete copies
of which filings have been furnished to the Lenders), (iii) Liabilities and
Contingencies incurred in the ordinary course of business and consistent with
past practice since the date of the most recent

                                      -25-
<PAGE>
 
Financial Statements, which are not required to be disclosed on Schedules to
this Agreement, or (iv) those Liabilities which are not required to be disclosed
under GAAP.  The reserves, if any, reflected on the consolidated balance sheet
of IGI and the Subsidiaries included in the most recent Financial Statements are
appropriate and reasonable.  The Borrowers have not had and do not presently
have any contingent obligations, liabilities for taxes or unusual forward or
long-term commitments except as specifically set forth in the Financial
Statements or in Schedule "1" annexed hereto.

          (e) Except as otherwise reflected in the Pro Forma Balance Sheet or on
Schedule "6" or Schedule "8" to this Agreement, since the date of the most
recent Financial Statements, there has been no material adverse change in the
Working Capital, condition (financial or otherwise), assets, liabilities,
reserves, business, prospects, management or Business Operations of the
Borrowers, when taken individually or as a consolidated whole, including,
without limitation, the following:

               (i) there has been no change in any assumptions underlying, or in
any methods of calculating, any bad debt, contingency or other reserve relating
to IGI or any of the Subsidiaries;

               (ii) there have been no write-downs in the value of any inventory
of, and there have been no write-offs as uncollectible of any notes, accounts
receivable or other receivables of, IGI and the Subsidiaries, except for write-
downs and write-offs in the ordinary course of business and consistent with past
practice, none of which shall be material (and all of which are described in the
Schedules to this Agreement or in the Financial Statements);

               (iii)  no debts have been cancelled, no claims or rights of
substantial value have been waived and no properties or assets (real, personal
or mixed, tangible or intangible) have been sold, transferred, or otherwise
disposed of by IGI or any Subsidiary, except in the ordinary course of business
and consistent with past practice;

               (iv)  there has been no change in any method of accounting or
accounting practice utilized by IGI or any of the Subsidiaries;

               (v)  no material casualty, loss or damage has been suffered by
IGI or any of the Subsidiaries, regardless of whether such casualty, loss or
damage is or was covered by insurance; and

               (vi)  no action described in this Section 3.01(e) has been agreed
to be taken by IGI or any of the Subsidiaries.

                                      -26-
<PAGE>
 
          (f) The Borrowers have heretofore furnished to the Lenders the pro
forma consolidated balance sheet of the MPS Group as of September 30, 1995, but
giving pro forma effect to the Spin-Off and all capital contributions to the MPS
Group in connection therewith.  Such pro forma balance sheet fairly reflects the
consolidated financial condition of the MPS Group as of the date thereof on a
pro forma basis as aforesaid.  After giving effect to the Spin-Off, except as
set forth on Schedule "14" to this Agreement, (i) none of the Borrowers has any
ongoing liability or obligation (fixed or contingent) in respect of any members
of the MPS Group or any debts, liabilities or obligations of any member of the
MPS Group, and (ii) none of the Borrowers has any ongoing obligations to any
member of the MPS Group or is owed any debt or obligation by any member of the
MPS Group.

authority to own its properties and to carry on its businesses as now conducted

to date, and (ii) By-Laws of each of the Borrowers, together with all amendments
thereto, have been furnished to the Lenders.

     Section 3.03.  Authorization.  The execution, delivery and performance by

provision of Applicable Law, any order of any court or other agency of
government, any provision of the Certificates of Incorporation or By-Laws of the
Borrowers, or any Contract, indenture, agreement or other instrument to which
any of the Borrowers is a party, or by which any of the Borrowers or any of its
assets or properties are bound, or (b) be in conflict with, result in a breach
of, or constitute (after the giving of notice of lapse of time or both) a
default under, or, except as may be provided in this Agreement, result in the
creation or imposition of any Lien of any nature whatsoever upon any of the
property or assets of any of the Borrowers pursuant to, any such Contract,
indenture, agreement or other instrument.  Except in respect of the filing of a
Form 10 (including amendments thereto) and/or a Form 8-

material adverse effect on any of such assets or on the business, operations,
properties, assets or condition, financial or otherwise, of the Borrowers.

     Section 3.05.  Material Contracts.  Except as disclosed on Schedule "5"

instrument or subject to any charter or other corporate restriction materially
adversely affecting its business, properties, assets, operations or condition,
financial or otherwise, or is subject to any liability or obligation under or
relating to any collective bargaining agreement, or in default in the
performance, observance or fulfillment of any of the obligations, covenants or
conditions contained in any Contract, agreement or instrument to which it is a

annexed hereto, before giving effect to the Spin-Off, IGI has no Subsidiaries

December 31, 1994; and after giving effect to the Spin-Off, other than the
elimination of the members of the MPS Group as Subsidiaries, IGI's Subsidiaries
are as they were immediately prior to the Spin-Off.  Neither IGI nor any
existing Subsidiaries owns any capital stock, equity or assets of any other

as set forth on Schedule "10" annexed hereto.

     Section 3.10.  Solvency.  The Spin-Off, and the borrowings made and to be
     -----------------------                                                  
made by the Borrowers under this Agreement, do not and will not render the
Borrowers insolvent or with unreasonably small capital for their business; the
fair saleable value of all of the assets and properties of the Borrowers do now,
and will, upon the funding of the Loans contemplated hereby and after giving
effect to the Spin-Off, exceed the aggregate Liabilities and Indebtedness of the
Borrowers (including Contingent Liabilities); none of the Borrowers is
contemplating either the filing of a petition under any state or federal

portion of its assets or property; and the Borrowers have no knowledge of any
Person contemplating the filing of any such petition against the Borrowers.

     Section 3.11.  Full Disclosure.  No statement of fact made by or on behalf
     ------------------------------                                            
of any of the Borrowers in this Agreement, in any Security Document, or in any
agreement, certificate or schedule furnished to the Lenders pursuant hereto

and amendments thereto, for the fiscal period from January 1, 1990 through
September 30, 1995, as filed with the SEC) contains or will contain any untrue
statement of a material fact, or omits or will omit to state any material fact
necessary to make any statements contained herein or therein not misleading.
Except for matters of a general economic or political nature which do not affect
the Borrowers uniquely, there is no fact presently known to the Borrowers which
has not been disclosed to the Lender, which materially adversely affects, or so
far as the Borrowers can foresee, will materially adversely affect, their
property, business, operations or condition (financial or otherwise).

     Section 3.12.  No Investment Company.  None of the Borrowers is an
     ------------------------------------                              
"investment company", or a company "controlled" by an "investment company", as
such terms are defined in the Investment Company Act of 1940, as amended.

     Section 3.13.  Margin Securities.  None of the Borrowers owns or has any
     --------------------------------                                        
present intention of acquiring any "margin security"

                                      -30-
<PAGE>
 
within the meaning of Regulation G (12 CFR Part 207), or any "margin stock"
within the meaning of Regulation U (12 CFR Part 221), of the Board of Governors
of the Federal Reserve System (herein called "margin security" and "margin
stock").  None of the proceeds of the Loans will be used, directly or
indirectly, for the purpose of purchasing or carrying, or for the purpose of
reducing or retiring any indebtedness which was originally incurred to purchase
or carry, any margin security or margin stock or for any other purpose which
might constitute the transactions contemplated hereby a "purpose credit" within
the meaning of said Regulation G or Regulation U, or cause this Agreement to
violate any other regulation of the Board of Governors of the Federal Reserve
System or the Securities Exchange Act of 1934, as amended, or any rules or
regulations promulgated under such statutes.

     Section 3.14.  Tax Returns.  Except as otherwise set forth in footnotes to
     --------------------------                                                
the consolidated balance sheet of Borrowers as at December 31, 1994, and except
for any returns currently on extension pursuant to properly filed extension, the
Borrowers have filed all federal, state and local tax returns required to be
filed by any of them and have paid or made adequate provision (as reflected in
the balance sheets described in Section 3.01 hereof) for the payment of all
federal, state and local taxes, charges and assessments.

     --------------------                                                      
none of the Borrowers nor any ERISA Affiliate of any of the Borrowers maintains
or has any obligation to make any contributions to any pension, profit sharing
or other similar plan providing for deferred compensation to any employee.  With
respect to any such plan(s) as may now exist or may hereafter be established by
the Borrowers or any ERISA Affiliate of any of the Borrowers, and which
constitutes an "employee pension benefit plan" within the meaning of 
Section 3(2) of ERISA, except as set forth on Schedule "7": (a) the Borrowers or
the subject ERISA Affiliate have paid and shall cause to be paid when due all
amounts necessary to fund such plan(s) in accordance with its terms, (b) except
for normal premiums payable by the Borrowers to the Pension Benefit Guaranty
Corporation ("PBGC"), the Borrowers or the subject ERISA Affiliate have not
taken and shall not take any action which could result in any Liability to the
PBGC, or any of its successors or assigns, (c) the present value of all vested
accrued benefits thereunder shall not at any time exceed the value of the assets
of such plan(s) allocable to such vested accrued benefits, (d) there have not
been and there shall not be any transactions such as would cause the imposition
of any tax or penalty under Section 4975 of the Code or under Section 502 of
ERISA, which would adversely affect the funded benefits attributable to the
Borrowers or the subject ERISA Affiliate, (e) there has not been and there shall
not be any termination or partial termination thereof (other than a partial
termination resulting solely from a reduction in the number of employees of the
Borrowers or an ERISA Affiliate of the

                                      -31-
<PAGE>
 
Borrowers, which reduction is not anticipated by the Borrowers), and there has
not been and there shall not be any "reportable event" (as such term is defined
in Section 4043(b) of ERISA) on or after the effective date of Section 4043(b)
of ERISA with respect to any such plan(s) subject to Title IV of ERISA, (f) no
"accumulated funding deficiency" (as defined in Section 412 of the Code) has
been or shall be incurred on or after the effective date of Section 412 of the
Code, (g) except as otherwise reflected on Schedule "7" annexed hereto, such
plan(s) have been and shall be determined to be "qualified" within the meaning
of Section 401(a) of the Code, and have been and shall be duly administered in
compliance with ERISA and the Code, and (h) the Borrowers are not aware of any
fact, event, condition or cause which might adversely affect the qualified
status thereof.  As respects any "multiemployer plan" (as such term is defined
in Section 3(37) of ERISA) to which any of the Borrowers or any ERISA Affiliate
thereof has heretofore been, is now, or may hereafter be required to make
contributions, such Borrower or such ERISA Affiliate has made and shall make all
required contributions thereto, and there has not been and shall not be any
"complete withdrawal" or "partial withdrawal" (as such terms are respectively
defined in Sections 4203 and 4205 of ERISA) therefrom on the part of the
Borrowers or such ERISA Affiliate.

     Section 3.16.  Compliance with Laws.  The Borrowers are in compliance in

all material respects with all occupational safety, health, wage and hour,
employment discrimination, environmental, flammability, labelling and other
Applicable Law which are material to their respective businesses and the
Business Operations, and the Borrowers are not aware of any state of facts,
events, conditions or occurrences which may now or hereafter constitute or
result in a violation of any of such Applicable Law, or which may give rise to
the assertion of any such violation, the effect of which could have a material
adverse effect on any Borrower.

     Section 3.17.  Licenses and Permits.  The Borrowers have all federal, state
     -----------------------------------

          (c) During the term of this Agreement, and for so long as any Loans
remain outstanding, the Borrowers shall comply in all material respects with all

Lender of any and all claims, demands or Notices received under any
Environmental Laws and the Borrowers' response thereto.

hereof, the occurrence of which shall automatically effect acceleration,

                                      -50-

VIII.     PARTICIPATING LENDERS; ASSIGNMENT.
          --------------------------------- 

     Section 8.01.  Participations.  Anything in this Agreement to the contrary
     -----------------------------                                             
notwithstanding, each Lender may, at any time and from time to time, without the
requirement of any consent in the case of a participation to an Affiliate of
such Lender, and otherwise with the prior written consent of a majority in
interest of the other Lenders (which consent shall not be unreasonably withheld
or delayed), without in any manner affecting or impairing the validity of any
Obligations or any collateral security therefor, transfer, assign or grant
participating interests in the Loans as such Lender shall in its sole discretion
determine, to such other financial institutions (the "Participants") as such
Lender may determine.  Upon any such transfer, assignment or granting of
participating interests, the Participants shall be deemed to be included within
the term "Lender" for all purposes of this Agreement and the Exhibits hereto,
subject to such agreements and arrangements as the originating Lender and the
Participants may agree upon.  Each Lender shall endeavor to give written notice
to the Borrowers upon the granting of any such participations, but the failure
to give any such notice shall not affect or impair the participating interests
so established.  Notwithstanding the granting of any such participating
interests: (a) the Borrowers shall look solely to the Lender granting such
participating interest, in respect of the subject Lender's interest, for all
purposes of this Agreement and the transactions contemplated hereby, (b) the
Borrowers shall at all times have the right to rely upon any waivers or consents
signed by the Agent as being binding upon all of the Participants,

                                      -51-
<PAGE>
 
and (c) all communications in respect of this Agreement and such transactions
shall remain solely between the Borrowers and the Agent and the original Lenders
hereunder.

     -----------------------                                             
notwithstanding, each Lender may, at any time and from time to time, without the
requirement of any consent in the case of a transfer or assignment as part of a
sale of loans by the subject Lender in an aggregate principal amount of
$100,000,000 or more, and otherwise with the prior written consent of a majority
in interest of the other Lenders (which consents may be withheld in each
Lender's sole and absolute discretion), without in any manner affecting or
impairing the validity of any Obligations or any collateral security therefor,
transfer and assign all or any portion of its interest in this Agreement, the
Notes, the Security Documents, and the Loans to any other commercial banking
institution as such Lender shall determine (an "Assignee Lender").  Upon any
such transfer or assignment, the Assignee Lender shall be deemed to succeed to
the rights and obligations of a "Lender" for all purposes of this Agreement and
the Exhibits hereto.  Each Lender shall endeavor to give written notice to the
Borrowers prior to making any such transfer or assignment, but the failure to
give any such notice shall not affect or impair the assignment so effected.


IX.  THE AGENT; AGREEMENTS AMONG LENDERS
     -----------------------------------

     Section 9.01. Appointment, Powers and Immunities.  Each Lender hereby
     ------------------------------------------------                     
irrevocably appoints and authorizes Fleet to act as administrator of the Loans
and the credit facilities hereunder, and as the Lenders' Agent hereunder and
under the Security Documents with such powers as are specifically delegated to
the Agent by the terms of this Agreement and the Security Documents together
with such other powers as are reasonably incidental thereto.  The Agent shall
have no duties or responsibilities or authority except those expressly set forth
in this Agreement and the Security Documents and shall not be a trustee for the
Lenders.  The Agent shall not be responsible to the Lenders for any recitals,
statements, representations or warranties contained in this Agreement, the
Notes, the Security Documents, or any certificate or other document referred to
or provided for in, or received by any of them under, this Agreement or the
Security Documents, or for the value, validity, effectiveness, genuineness,
enforceability or sufficiency of this Agreement or the Security Documents or any
other document referred to or provided for herein or therein or for the
collectibility of the Loans or for the validity, effectiveness of any
assignment, mortgage, pledge, security agreement, financing statement, document
or instrument, or for the filing, recording, re-filing, continuing or re-
recording of any document or for any failure by any of the Borrowers to perform
any of its agreements, covenants or Obligations hereunder or under the Security
Documents.

                                      -52-
<PAGE>
 
The Agent may, other than for purposes of normal Loan administration, employ
agents and attorneys-in-fact and shall not be answerable, except as to money or
securities received by it or its authorized agents, for the negligence or
misconduct of any such agents or attorneys-in-fact selected by it with
reasonable care.  Neither the Agent nor any of its directors, officers,
employees or agents shall be responsible to the Lenders for any action taken or
omitted to be taken by it or them hereunder or under the Security Documents in
connection herewith or therewith, except for its or their own gross negligence
or willful misconduct.

     Section 9.02.  Reliance by Agent.  Except to the extent that such reliance
     --------------------------------                                          
constitutes gross negligence or willful misconduct, the Agent shall be entitled
to rely upon any certification, notice or other communication (including any
thereof by telephone, telecopier, telex, telegram or cable) believed by it to be
genuine and correct and to have been signed or sent by or on behalf of the
proper person or persons, and upon advice and statements of legal counsel,
independent accountants and other experts selected by the Agent.  As to any
matters not expressly provided by this Agreement, the Security Documents or the
other instruments and agreements executed in connection with the Loans, the
Agent shall in all cases be fully protected in acting, or in refraining from
acting, hereunder, or under the Security Documents, in accordance with written
instructions signed by the Requisite Lenders.

     Section 9.03.  Events of Default.  The Agent shall not be deemed to have
     --------------------------------                                        
knowledge of the occurrence of a Default or an Event of Default (other than the
non-payment of principal of or interest on Loans) unless the Agent has itself
issued a notice, or has received notice from the Borrowers or a Lender
specifying such Default or Event of Default and stating that such notice is a
"Notice of Default".  In the event that the Agent receives such a notice, the
Agent shall provide the Lenders with prior written notice of any actions or
omissions proposed to be taken by the Agent with respect thereto, unless the
giving of such notice is impracticable for reasons of safety or preservation of
collateral.  The foregoing notwithstanding, the Agent and each of the Lenders
hereby agrees to share with one another any and all material information
regarding the Borrowers which may come into the possession of the Agent or the
Lenders from time to time, provided that neither the Agent nor the Lenders shall
be under any duty or obligation to provide any analysis of any such information
so provided, or to determine therefrom whether a Default or an Event of Default
has occurred.

     Section 9.04.  Waivers; Amendments; Event of Default.
     ---------------------------------------------------- 

     (a) The Agent may, with the prior written consent of the Requisite Lenders,
enter into any amendment or modification of this Agreement and/or any of the
Security Documents, and the Borrowers shall be entitled to rely upon any such
amendment or modification

                                      -53-
<PAGE>
 
executed and delivered by the Agent as being made on behalf of all of the
Lenders.  Such amendments and modifications may include, without limitation, any
amendment or modification that would (i) extend the stated maturity of any of
the Loans, (ii) increase the principal amounts of any of the Loans (provided
that no specific consent shall be required to make additional Advances from time
to time in accordance with this Agreement), (iii) change the interest rate
charged on any of the Loans (provided that no specific consent shall be required
for any such change provided for in the Notes), (iv) forgive or extend any
payment of principal or interest payable with respect to any of the Loans, (v)
modify any of the financial covenants contained in Sections 5.08 through 5.11
hereof, or any of the covenants contained in Article VI hereof, (vi) release any
material portion of the collateral security for the Obligations (provided that
no specific consent shall be required in respect of any such release which is
required in accordance with the terms of any of the Security Documents as in
effect on the Agreement Date), (vii) use any of such collateral security to
secure any indebtedness or liabilities other than the Obligations, or (viii)
grant any waiver which would have the practical effect of implementing any
amendment or modification described in the foregoing clauses (i) through (vii).

     (b) Upon the giving of any Notice of Default required under Section 9.03
above, Fleet (as Agent), for itself and on behalf of the Lenders, shall (subject
to the provisions of this Article IX) take such action or actions, assert such
rights, exercise such remedies and/or waive such Default(s) or Event(s) of
Default or refrain from taking such actions with respect thereto, as the Lenders
shall mutually agree upon, including, without limitation, (i) the cessation of
any further Advances, the acceleration of any or all of the Obligations, the
institution of suit, and/or the commencement of foreclosure proceedings in
respect of the collateral under the Security Documents (individually and
collectively, hereinafter referred to as a "Loan Acceleration Action"), or (ii)
the waiving of any Default(s) or Event(s) of Default, the granting of any
moratoriums in payment of required payments under any Notes, and/or the
extension of the term of any Loans, for the purposes of assisting the Borrower
and "working out" the Loans (individually and collectively, hereinafter referred
to as a "Loan Workout Action").  In the event that the Lenders are unable to
mutually agree upon the appropriate Loan Acceleration Action or Loan Workout
Action, or forbearance from any such action, as the case may be, within ten (10)
Business Days after the Lenders receive Notice of Default or any proposed action
or omission by a Lender, then: (A) if the subject Event of Default is a "Non-
Fundamental Default" (as such term is hereinafter defined), then, and in such
event, the provisions of Section 9.04(c) hereof shall be applicable; and (B) if
the Default or Event of Default is a "Fundamental Default" (as such term is
hereinafter defined), then, and in such event, the provisions of Section 9.04(d)
hereof shall be applicable.

     (c)  (i)  In the event that there shall occur and be continuing any Event
of Default hereunder, other than an Event of Default of the nature specified in
Section 9.04(d) hereof (a "Non-Fundamental Default"), then Fleet (as Agent) may
at any time, by consent or agreement (written or oral) of the holders of more
than fifty (50%) percent of the combined Revolving Credit Commitment and Line of
Credit Commitment, take such Loan Workout Action or Loan Acceleration Action as
such Requisite Lenders shall deem to be appropriate, including but not limited
to the institution of foreclosure proceedings in respect of the collateral for
the Obligations, all as contemplated by Section 9.04(b) above and pursuant to
the Security Documents; provided, however, that the Agent may not thereby,
                        --------  -------                                 
without the consent of the Requisite Lenders for such purpose, grant any waiver
or effect any amendment or modification requiring supermajority consent pursuant
to Section 9.04(a) hereof.

          (ii) Following the occurrence and during the continuance of any Non-
Fundamental Default, notwithstanding a request for any specific Loan
Acceleration Action by any of the Lenders, if the Requisite Lenders shall not
agree with the proposed Loan Acceleration Action, then, and in such event,
neither the Agent nor any Lender shall, without the express prior written
consent of the Requisite Lenders, take any such Loan Acceleration Action for a
period of ninety (90) days following the date of such Notice of Default (the
"Standstill Period").  If such Non-Fundamental Default(s) shall still be
continuing at the expiration of such ninety (90) day Standstill Period, unless
the specific Loan Acceleration Action previously requested by any Lender is
retracted or modified in writing by such Lender, then, and in such event, Fleet
(as Agent) shall promptly, on behalf of all Lenders, commence Loan Acceleration
Action to the extent and in the manner that Fleet (as Agent) determines in good
faith that any Loan Acceleration Action is then requested by Lenders
collectively constituting the Requisite Lenders, failing which, Mellon may, if
Mellon then holds at least one-third of the combined Revolving Credit Commitment
and Line of Credit Commitment, unilaterally commence such Loan Acceleration
Action as Agent on behalf of all of the Lenders.

          (iii)     Notwithstanding the occurrence of any one or more Event(s)
of Default constituting Non-Fundamental Defaults, if, during the pendency of any
Standstill Period, there shall occur and be continuing any Event(s) of Default
constituting a "Fundamental Default" as defined in Section 9.04(d) hereof, such
Standstill Period shall terminate on a date which shall be the earlier of thirty
(30) days from the occurrence of such Fundamental Default(s) or ninety (90) days
from the date such Standstill Period originally commenced.

          (iv) During the pendency of any Standstill Period, if and for so long
as any Lender (or group of Lenders) holding not less than one-third of the
combined Revolving Credit Commitment and Line

                                      -55-
<PAGE>
 
of Credit Commitment shall continue to fund its (or their) pro rata percentage
                                                           --- ----           
of the Advances, then the other Lender(s) shall likewise continue to fund its
pro rata percentage of the Advances.
- --- ----                            

     (d) In the event that there shall occur and be continuing any Event(s) of
Default (individually a "Fundamental Default" and collectively "Fundamental
Defaults"):

               (i) of the nature specified in Section 7.01(b) of this Agreement;
or

               (ii) with respect to (A) any of the financial covenants contained
in any of Sections 5.08 through 5.11 hereof by a variance of more than ten (10%)
percent which is not fully cured in the next succeeding fiscal quarter, or (B)
any of the financial covenants contained in any of Sections 5.08 through 5.11
hereof by a variance of more than twenty (20%) percent; or

               (iii)  of the nature specified in Sections 7.01(e), 7.01(g),
7.01(h), 7.01(i) or 7.01(j) of this Agreement;

then, provided that such Fundamental Default shall still be continuing thirty
(30) days after the occurrence thereof, Fleet (as Agent) shall promptly commence
such Loan Acceleration Action as may be requested in writing by the holders of
the greatest portion of the combined Revolving Credit Commitment and Line of
Credit Commitment who request specific Loan Acceleration Action, including but
not limited to the institution of foreclosure proceedings in respect of the
collateral for the Obligations; failing which, Mellon may, if it then holds more
than one-third of the combined Revolving Credit Commitment and Line of Credit
Commitment, unilaterally commence such Loan Acceleration Action as Agent on
behalf of all of the Lenders.

     (e) Each of the Lenders shall, at all times, act in good faith to mutually
agree upon all Loan Workout Actions and/or Loan Acceleration Actions to be taken
in respect of the Loans and other Obligations.  In the event and to the extent
that the Agent receives conflicting instructions as to any action to be taken,
the Agent shall use its good faith judgment to determine and implement those
specific actions requested by the Requisite Lenders.  In the event that the
Agent receives conflicting instructions from two Lenders (or two groups of
Lenders) each holding fifty (50%) percent of the combined Revolving Credit
Commitment and Line of Credit Commitment, the Agent shall not, and shall not be
required to, undertake any action requested by either such Lender (or group of
Lenders), except to the extent that such instructions are not materially
inconsistent or amended by either Lender (or group of Lenders) so as to be not
materially inconsistent.

     (f) In the event that Mellon shall, at any time, have the right to take
action under this Section 9.04 as Agent for the

                                      -56-
<PAGE>
 
benefit of the Lenders, then Fleet shall cooperate with Mellon in all respects
to enable Mellon to take such action as it is authorized to take under this
Section 9.04, including but not limited to (i) assigning to Mellon such of
Fleet's rights and responsibilities as Agent under this Agreement as may be
necessary or appropriate for Mellon to act under the circumstances, (ii)
delivering to Mellon such books and records as may be requested by Mellon and
necessary or appropriate under the circumstances, (iii) turning over to Mellon
any collateral for the Obligations then held by Fleet (as Agent), and/or (iv)
executing and delivering to Mellon any and all such agreements, instruments,
certificates and other documents as may be necessary or appropriate for Mellon
to undertake and carry out such action as it is permitted to take hereunder.

     (g) Neither Fleet nor, if applicable, Mellon, shall be required to take any
action as Agent under this Section 9.04 if Fleet or Mellon, as the case may be,
shall have requested and the Lenders shall not have provided reasonable
indemnity against the reasonable costs, expenses and liabilities which might be
incurred by reason of such action, which indemnity shall entitle Fleet or
Mellon, as the case may be, to receive reimbursement for such reasonable costs,
expenses and liabilities out of the proceeds of collateral (if applicable) or
otherwise from the Lenders as and when such costs, expenses and liabilities are
incurred.

     (h) Except as otherwise specified in this Section 9.04, Fleet shall, and
shall be permitted in its discretion to, administer the Loans in a manner
consistent with its normal lending and business practices, and to enforce the
provisions, rights and remedies pursuant to this Agreement and the Security
Documents in a manner consistent herewith and therewith and in Fleet's good
faith judgment.

     (i) Nothing contained in this Section 9.04 shall be deemed to grant to the
Borrowers any indulgence or grace period in respect of any of their covenants or
obligations under this Agreement (or any right to expect or receive any such
indulgence or grace period), except as otherwise specifically provided in other
Sections of this Agreement.  Nothing contained in this Section 9.04 shall be
deemed to prohibit or impair the Agent, regardless of the lack of any requisite
consents of Lenders, from taking action in respect of any of the collateral
under the Security Documents if same are perishable or threaten to decline
speedily in value.

     Section 9.05.  Agent's Rights as a Lender.  With respect to its interest in
     -----------------------------------------                                  
the Revolving Credit Commitment and the Line of Credit Commitment and the Loans
made by it, the Agent in its capacity as a Lender hereunder shall have the same
rights and powers hereunder as any other Lender, and may exercise the same as
though it were not acting as Agent, and the term "Lender" or "Lenders" shall,
unless the context otherwise indicates, include

                                      -57-
<PAGE>
 
the Agent in its individual capacity.  To the same extent as such rights are
available to any Lender in accordance with and subject to this Agreement, the
Agent and its Affiliates (including, without limitation, Mellon and its
Affiliates in the event that Mellon shall at any time be acting as or performing
duties of the Agent hereunder) may (without having to account therefor to any
other Lender) accept deposits from, lend money to and generally engage in any
kind of banking, trust or other business with the Borrowers or their Affiliates,
as if it were not acting as Agent.  The Agent (including, without limitation,
Mellon and its Affiliates in the event that Mellon shall at any time be acting
as or performing duties of the Agent hereunder) may accept, for its sole
account, fees and other consideration from the Borrower or its Affiliates, for
services in connection with this Agreement or the Security Documents or
otherwise.

     Section 9.06. Indemnification.  Each Lender shall, ratably in accordance
     -----------------------------                                           
with its ratable interest in the Loans, indemnify the Agent (to the extent not
reimbursed by the Borrower) against any cost, expense (including counsel fees
and disbursements), claim, demand, action, loss or liability (except such as
result from the Agent's gross negligence or willful misconduct) that the Agent
may suffer or incur in connection herewith or any action taken or omitted by the
Agent hereunder.  Such right to indemnification shall be available to each Agent
from time to time hereunder, including (without limitation) Mellon in the event
that Mellon shall at any time be acting as or performing duties of the Agent
hereunder.

     Section 9.07.  Credit Decision.  Each Lender acknowledges that it has,
     ------------------------------                                        
independently and without reliance upon the Agent or any other Lender, and based
on such documents and information as it has deemed appropriate, made its own
credit analysis and decision to enter into this Agreement.  Each Lender also
acknowledges that it will, independently and without reliance upon the Agent or
any other Lender, and based on such documents and information as it shall deem
appropriate at the time, continue to make its own credit decisions in taking or
not taking any action under this Agreement.

     Section 9.08.  Successor Agent.  The Agent (a) may resign at any time by
     ------------------------------                                          
giving thirty (30) days' written notice thereof to the Lenders and the
Borrowers, and (b) shall be deemed to have resigned upon any bankruptcy,
insolvency or receivership of the Agent; provided, that any such resignation
shall be effective at the time specified below.  Upon any such resignation, the
Requisite Lenders shall have the right, but not the obligation, to appoint a
successor Agent (which successor shall be subject to the Borrower's prior
written approval (such approval not to be unreasonably withheld or delayed) in
the event that such successor is not also a Lender).  If no successor Agent
shall have been so appointed by the Requisite Lenders, and shall have accepted
such appointment, within thirty (30) days after the resigning Agent gives notice
of

                                      -58-
<PAGE>
 
resignation, then the resigning Agent may, on behalf of the Lenders, appoint a
successor Agent, which shall be a commercial bank organized or licensed under
the laws of the United States of America or of any State thereof and having a
combined capital and surplus of at least $50,000,000.  Upon the acceptance of
its appointment as Agent hereunder by a successor Agent, such successor Agent
shall thereupon succeed to and become vested with all the rights and duties of
the resigning Agent, and the resigning Agent shall be discharged from its duties
and obligations hereunder.  After any resigning Agent's resignation hereunder as
Agent, the provisions of this Article IX shall inure to its benefit as to any
actions taken or omitted to be taken by it while it was Agent.

     Section 9.09.  Several Liability of Lenders; Failure to Lend.
     ------------------------------------------------------------ 

     (a) No Lender shall incur or assume any liability or obligation to any
Borrower by reason of any other Lender failing or refusing to make Advances or
otherwise lend the amounts required by this Agreement; it being understood and
agreed that all obligations of the Lenders to make any and all Loans hereunder
are several, and not joint and several.

     (b) In the event and to the extent that any Lender shall, for any reason or
no reason, fail or refuse to make its pro rata portion of the Advances otherwise
                                      --- ----                                  
required to be made hereunder, then the other Lender(s) may (but shall not be
obligated to) make such Advances on behalf of the defaulting Lender; in which
event such non-defaulting Lender may be reimbursed for any such Advances so made
on behalf of the defaulting Lender out of the defaulting Lender's otherwise
applicable share of the initial proceeds of all payments and collections
received under the Borrowers' Loan accounts, or out of the initial net proceeds
received from the sale or liquidation of any collateral under the Security
Documents in the event of a foreclosure thereof.

     Section 9.10.  Sharing and Remittance of Payments and Collateral.
     ---------------------------------------------------------------- 

     (a) In order to minimize, to the extent feasible, the number of transfers
of funds under this Agreement, (i) the Agent may, in its discretion, fund to the
Borrowers (within the limit of the Revolving Credit Commitment or the Line of
Credit Commitment, as the case may be), upon receipt of any borrowing request
from the Borrowers, the full amount of the requested borrowing, and (ii) the
Borrowers shall be entitled to make any and all payments (whether for principal,
interest, fees or otherwise) hereunder to the Agent on behalf of the Lenders.
Upon any such advance or receipt of funds by the Agent, the Agent shall notify
(telephonically or in such other manner as the Agent may deem appropriate) each
of the Lenders of the amounts thereof, and the Lenders shall remit to the Agent,
or the Agent shall remit to the Lenders (as the case may be), the subject
Lender's pro rata share of the subject

                                      -59-
<PAGE>
 
disbursement or collection, which remittance shall be made (i) if the subject
notice or receipt of funds is received prior to 1:00 P.M. eastern time, on the
same day as such notice or receipt of funds is received, and (ii) if such notice
or receipt of funds is received at or after 1:00 P.M. eastern time, then not
later than the next succeeding Business Day following the receipt of such notice
or receipt of funds.  Any and all payments hereunder shall be made by wire
transfer of same-day Federal Reserve Funds, and to the extent that any payments
(either by or to the Agent) are not made on the same day as the underlying
disbursement or collection, then interest on the subject amount shall be charged
or credited (as the case may be) to the next amounts payable by or to the
subject Lender.

     (b) All collections received by the Agent or any Lender(s) in respect of
the Borrowers shall be applied in accordance with this Agreement, and all
collections applied to Advances and/or interest thereon or fees in respect
thereof shall be allocated ratably among the Lenders in proportion to their
relative interests in such Loans, with funds remitted, in accordance with
Section 9.10(a) above, by wire transfer of same-day Federal Reserve Funds for
all fees, interest payments and other amounts payable to the Lenders under this
Agreement, including amounts payable in respect of the principal amounts of, and
accrued interest on, the Loans.  If requested by the Agent, each Lender shall,
promptly following receipt of each payment under this Section 9.10(b), confirm
its receipt by a written acknowledgment telecopied to the Agent.

     (c) If and to the extent that any payment received by any Lender in respect
of the Loans (whether principal, interest or otherwise) shall be rescinded or
must otherwise be returned for any lawful reason, then each of the Lenders
shall, upon notice thereof, remit its proportionate share of the amount(s) so
rescinded or returned.

     (d) Except for any prepayments made by the Borrowers while no other
Obligations shall be then due and payable (which prepayments shall be applied to
those Obligations and in the manner directed by the Borrower), and any other
payments received at any time when no other Obligations shall be then due and
payable (which payments shall be applied in reduction of the outstanding
Advances), all payments received by the Agent or any Lender(s) from the Borrower
(whether by means of direct payment, by charge or set-off to the Borrower's Loan
accounts or deposit accounts, out of the proceeds of collateral, or otherwise)
shall be applied and disbursed by the Agent to the Lenders, ratably in
proportion to their relative interests therein, as follows:

          (i) first, to any Revolving Credit Advances outstanding in excess of
the Revolving Credit Commitment as in effect at such time (provided that nothing
herein contained shall

                                      -60-
<PAGE>
 
be deemed to permit any such excess Revolving Credit Advances to be outstanding
at any time);

          (ii) next, to any Line of Credit Advances outstanding in excess of the
Line of Credit Commitment as in effect at such time (provided that nothing
herein contained shall be deemed to permit any such excess Line of Credit
Advances to be outstanding at any time);

          (iii)next, to accrued interest due and payable on the Advances,
in such order and application as the Agent may determine;

          (iv) next, to any unpaid Revolving Credit Commitment Fee and/or Line
of Credit Commitment Fee then due and payable, in such order and application as
the Agent may determine; and

          (v)  next, to any other Obligations then due and payable.

The foregoing notwithstanding, the Agent shall be entitled, prior to any
application of payments hereunder, to receive reimbursement out of such payments
for any previously unreimbursed reasonable costs and expenses incurred by the
Agent pursuant to any of the Security Documents.

     (e) To the extent of any payments made by the Borrower to the Agent as
administrator of the Loans, the Borrower shall be entitled to presume that such
payments have effectively been made to the Lenders under this Agreement, and the
Borrower shall have no liability to any Lender with respect to any payments
misapplied, misappropriated, or otherwise improperly disbursed or not disbursed
by the Agent as administrator.

     Section 9.11.  Buyout Rights.  Upon any bankruptcy, insolvency or
     ----------------------------                                     
receivership of any Lender, each of the other Lenders shall have the right (but
not the obligation), at any time thereafter, to purchase, ratably in proportion
to their respective interests in the Revolving Credit Commitment and the Line of
Credit Commitment (or in such other proportions as such other Lenders may
mutually agree), the bankrupt or insolvent Lender's interest in the Advances, at
an aggregate price equal to the principal balance and unpaid accrued interest
and fees on the interest being purchased as of the date of purchase, such
purchase price to be paid on the date of purchase by wire transfer of Federal
Reserve funds.  Upon any such purchase, each purchasing Lender shall succeed to
the applicable portion of the bankrupt or insolvent Lender's interest in the
Revolving Credit Commitment and the Line of Credit Commitment.

     ------------------------                                                
representations and warranties made herein and in the certificates delivered
pursuant hereto, shall survive the making by the Lenders of the Loans, and the
execution and delivery to the Lenders of the Notes, and shall continue in full
force and effect for so long as the Notes or any other Indebtedness or other
Obligations of the Borrowers to the Lenders are outstanding and unpaid.
Whenever in this Agreement any of the parties hereto is referred to, such
reference shall be deemed to include the successors and permitted assigns of
such party; and all covenants, promises and agreements in this Agreement
contained, by or on behalf of the Borrowers, shall inure to the benefit of the
successors and assigns of the Lenders.

     Section 10.02.  Indemnification.  The Borrowers hereby jointly and
     -------------------------------                                   
severally indemnify each of the Lenders and each of their respective directors,
officers, employees, attorneys and agents against, and agrees to hold each
Lender and such Persons harmless from, any and all losses, claims, damages and
liabilities and related expenses, including reasonable counsel fees and
expenses, incurred by either Lender or any such Person arising out of, in any
way connected with, or as a result of: (a) the use of any of the proceeds of the
Loans made by the Lenders to the Borrowers for the making, or furtherance, of
the consummation of the transactions contemplated by Section 2.04 above; (b)
this Agreement, the ownership and operation of the Borrowers' assets, including
all real properties and improvements or any Contract, the performance by the

foregoing, whether or not a Lender or its directors, officers, employees,
attorneys or agents are a party thereto; provided that such indemnity shall not
apply to any such losses, claims, damages, liabilities or related expenses
arising from (i) any unexcused breach by the subject Lender of any of its
obligations under this Agreement, (ii) the willful misconduct or negligence of
the subject Lender, provided that any such loss, claim, damage, liability or
expense is determined by a court of competent jurisdiction by final judgment to
have resulted from the willful misconduct or negligence of such Lender and the
further finding that such willful misconduct or negligence was the primary cause
thereof (i.e., more than 50% of the causation), or (iii) the breach of any
commitment or legal obligation of the subject Lender to any Person other than
the Borrowers or their Affiliates, provided that such breach is determined
pursuant to a final and nonappealable decision of a court of competent
jurisdiction.  The foregoing indemnity shall remain operative and in full force
and effect regardless of the expiration of the term of this Agreement, the
consummation of the transactions contemplated by this Agreement, the repayment
of any

                                      -62-

or all of the Loans, the invalidity or unenforceability of any term or provision
of this Agreement, the Security Documents or the Notes, any investigation made
by or on behalf of either Lender, and the content or accuracy of any
representation or warranty made by the Borrowers or their Affiliates under this
Agreement.  All amounts due under this Section 10.02 shall be payable on written
demand therefor.

     Section 10.03.  Governing Law.  This Agreement, the Notes and the Security
     -----------------------------                                             
Documents shall (irrespective of where same are executed and delivered) be
governed by and construed in accordance with the laws of the State of New
Hampshire (without giving effect to principles of conflicts of laws), except as

     ------------------------------------                                     
of any provision of this Agreement, the Notes or the Security Documents, nor any
consent to any departure by the Borrowers therefrom, shall in any event be
effective unless the same shall be set forth in writing duly signed or
acknowledged by the Requisite Lenders (or by the Agent if in accordance with
Section 9.04(a) hereof) and all of the Borrowers, and then such waiver or
consent shall be effective only in the specific instance, and for the specific
purpose, for which given.  No notice to or demand on the Borrowers in any
instance shall entitle the Borrowers to any other or future notice or demand in
the same, similar or other circumstances.

     Section 10.05.  Reservation of Remedies.  Neither any failure nor any delay
     ---------------------------------------                                    
on the part of either Lender or the Agent in exercising any right, power or
privilege hereunder, or under the Notes, any of the Security Documents, or any
other instrument given as security for any of the Obligations, shall operate as

other or future exercise, or the exercise of any other right, power or
privilege.

               -----------------------                                        
sublicensees) in achieving the aims of Section 4.2, MP (and its Affiliates) will
supply all of the manufacturing know-how in its possession or available to it
for manufacture of Licensed Products in the Field at no cost; provided, however,
reasonable costs to effect the transfer will be paid by IGEN.  To further assist
IGEN in IGEN's manufacture of Licensed Products, IGEN may send personnel to the
facilities of MP (or its Affiliates) at a time convenient for, and with the
prior approval of, MP and MP (or its Affiliates) shall provide the instruction
necessary for manufacturing Licensed Products.  If such instruction is carried
out within the first three (3) months after the Effective Date of this
Agreement, it shall be without charge to IGEN (or its Affiliates), but after
that, MP (or its Affiliates) shall be compensated for its employees time at an
agreed upon rate.  In addition, if IGEN (or its Affiliates or sublicensees)
requires assistance from MP (or its Affiliates) employees at any facility of
IGEN (or its Affiliates or sublicensees), IGEN shall pay an agreed upon daily
fee plus living and travel expenses as appropriate.

          4.4  Advertising and Promotion.  IGEN (and its Affiliates or
               --------------------------                             
sublicensees) shall have the responsibility for the preparation and
dissemination of all advertising and promotional materials including the
choosing and use of trade names and trademarks in 

                                      -6-

connection with the Licensed Products and shall pay all costs in connection
therewith. IGEN (and its Affiliates or sublicensees) may use the marks listed in
Appendix B without payment of any additional royalty.

          4.5  IGEN (and its Affiliates or sublicensees) agrees that MP may
control the nature and quality of the goods and the services on which IGEN (and
its Affiliates or sublicensees) use any of the licensed trademarks.  IGEN (and
its Affiliates or sublicensees) further acknowledges that MP (and/or the
trademark's owner if the trademark is licensed) has the right to inspect the
nature and quality of the goods or services which IGEN (and its Affiliates or
sublicensees) sell or render under any of the trademarks and that MP (and/or the
trademark's owner if the trademark is licensed) will be the sole judge of
whether IGEN (and its Affiliates or sublicensees) are meeting the required
nature and quality of the goods and services.  IGEN further agrees that all
sublicenses granted by it or its Affiliates will contain specific reference to
this right of MP.

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

          5.1  Patent Warranty.  MP warrants that at least basic patent
               ----------------                                        
applications covering the technology for use in making Licensed Products in the
Field have been filed, that some patents have been issued, and that other
applications have been filed, and that MP is not aware of any valid patents of
third parties which would be infringed by IGEN's, or its Affiliates or
sublicensees, making, using or selling Licensed Products.  This warranty does
not extend to variations or modifications of the Licensed Products distinct from
those products being made by IGEN (and its Affiliates or sublicensees) as of the
Effective Date of this Agreement.

          5.2  Obtaining Patents.  MP (on its own behalf and that of its
               ------------------                                       
Affiliates) agrees, at its own expense, to file and prosecute diligently patent
applications covering the Licensed Products in the countries of the United
States, the European Patent Office, Japan and Canada (known as Group "A"
countries) or other countries as it may be requested to do so by IGEN (known as
Group "B" countries), and to maintain where required, by payment of renewal fees
or taxes, any patents issued thereon.  MP shall be responsible for all patent
expenses relating to the Group "A" countries unless it decides to abandon such
patent or application and IGEN shall be responsible for the reasonable pro rata
expenses in the Group "B" countries, said pro rata expenses to be shared equally
on a country-by-country basis by all licensees of MP who request coverage in
that country.  If MP decides to abandon an application or patent, MP will inform
IGEN of its intent to abandon such patent or application in sufficient time that
IGEN may assume prosecution and/or ownership at its own expense and no further
royalties under that patent or application shall be due.  MP shall keep IGEN or
its counsel informed of all developments in connection with each filing and
prosecution, promptly furnishing to IGEN or its counsel copies of all
applications, official actions, amendments, issued patents and all other papers
filed or received.  All patents obtained pursuant to this Section 5.2 shall
become a part of the Licensed Patent Rights.

          5.3  Infringement Notice.  MP or IGEN, as the case may be, shall give
               --------------------                                            
prompt written notice to the other of any infringement known to MP or IGEN of a
Licensed Patent Right, and shall supply the other with such details of such
infringement as are actually in MP's or IGEN's possession.

          5.4  Infringement by Others.
               -----------------------

          5.4.1  In the event of any infringement of a Licensed Patent Right in
the Field, MP shall, if consistent with its business interests, institute such
proceedings or other actions as it deems advisable to prevent such infringement
and shall retain all recovery had from any infringer.

          5.4.2  If MP does not institute such proceedings or other actions
necessary to prevent such infringement within three (3) months after it learns
of such infringement, IGEN may, at its own expense, institute such proceedings
as may be appropriate to prevent such infringement.  MP shall join in any such
proceedings, if required.  In such event MP shall, upon the request of IGEN and
at IGEN's expense, formally assign to IGEN any cause of action it may have
against any such infringer of the Licensed Patent and execute all documents and
do all acts deemed necessary by IGEN for IGEN to prosecute and control such
proceedings or other actions brought by it, including, but not limited to, being
named as a party if legally required.

          5.4.3  Neither MP or IGEN has any obligation to institute any
proceedings or other actions to prevent such infringement.  However, which ever
party initiates such proceedings or actions shall be entitled to any recovery,
after paying any expenses incurred at its request by the other party.

          5.5  Infringement of Others' Proprietary Rights.
               -------------------------------------------

          5.5.1  MP has no obligation or liability to IGEN (and its Affiliates
or sublicensees) to hold harmless, indemnify or defend IGEN (and its Affiliates
or sublicensees) from and against any and all liabilities, losses, damages,
claims, demands, 

                                      -9-

suits, judgments, royalties, actions, causes of action, costs or expenses of any
nature whatsoever arising out of any infringement or alleged infringement of the
proprietary rights of others by a Licensed Product.

                           ARTICLE VI - IMPROVEMENTS
                           -------------------------

          6.1  MP and IGEN Improvements.  If at any time during the term of this
               -------------------------                                        
License Agreement MP (and its Affiliates or sublicensees) or IGEN (and its
Affiliates or sublicensees) shall, to the extend permitted by other agreements,
make or discover any Improvement of the Licensed Products useful in the Field
(such Improvement being limited to those improvements which would be dominated
by the claims of a Licensed Patent).  MP and IGEN, respectively, shall
communicate all details in respect thereof to the other party.  If MP(or its
Affiliates) makes such an Improvement, IGEN (and its Affiliates or sublicensees)
shall be entitled to use the same in the Field during the term of this Agreement
upon the same terms pursuant to this Agreement without paying any increased or
decreased royalty in respect thereof.  If MP obtains a patent in respect to any
such Improvement, it shall be included in the Patent Rights.  If IGEN (or its
Affiliates or sublicensees) makes such an Improvement, MP (and its Affiliates or
sublicensees) shall have the right to use it outside the Field during the term
of this Agreement.

          6.2  Joint Inventions.  In the event employees of MP and IGEN, or one
               -----------------                                               
of their Affiliates, are joint inventors as a result of inventions arising out
of the development of Licensed Products, any patent applications filed thereon
shall be owned by MP and IGEN shall have an exclusive license in the Field as
provided in Section 2.1.

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

          7.1  Obligations.  Except as expressly provided under this Agreement,
               ------------                                                    
each party agrees that it shall hold in confidence for the term of this
Agreement and for a period of five (5) years thereafter all confidential
information disclosed by or acquired from the other pursuant to this Agreement
and marked as confidential and shall not use such for the benefit of third
parties, or disclose such to third parties, without the prior written
authorization of the other party; provided, however, that neither party shall be
responsible for any inadvertent disclosure of confidential information provided
it has exercised the same standard of care as it exercises with respect to its
own information and further provided that the parties may, for the purpose of
health registration and exploitation of Licensed Products, transmit and disclose
such information to Affiliated companies, subsidiaries and agents. All
confidential information conveyed orally shall be treated as if it were conveyed
in writing, if it is conveyed again in a writing designated "confidential"
within ninety (90) days after such oral transmission.

          7.2  Exceptions.  The foregoing obligation shall not extend to
               -----------                                              
information which (i) at the time of disclosure or acquisition is part of the
public knowledge or literature or thereafter becomes part of the public
knowledge or literature otherwise than by unauthorized disclosure by the
receiving party, or (ii) at the time of disclosure or acquisition was in the
receiving party's possession as evidenced by its written records, or (iii)
become available to the receiving party from another source not bound to secrecy
by the disclosing party with respect to such information, or (iv) would be
required by Health Registration authorities and/or Government authorities.

and distribute the Licensed Products in any country without further royalty to
MP.

this Agreement, upon thirty (30) days notice to IGEN, if IGEN fails to make a
payment due under Paragraphs 3.1 or 3.2.

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

          Notwithstanding anything to the contrary contained herein, neither
party hereto shall be liable for damages or otherwise for failure to satisfy or
perform any obligation or duty to be satisfied or performed pursuant to the
terms and provisions of this License Agreement, if such failure is occasioned by
(a) Act of God, war, civil disorder or strikes or acts, regulations or decision
of governmental, judicial or administrative agencies or authorities, or other
circumstances beyond the control of the party hereto who has failed to satisfy
or perform, or (b) the suspension by any Governmental authority of a license or
similar authorization or approval necessary in connection with the manufacture
or sale of the Licensed Products; provided, however, that any such obligation or
duty, although the satisfaction or performance thereof has been postponed
pursuant to this Article VIII, shall remain in force and effect and shall be
satisfied and performed pursuant to this License

Agreement as soon as such satisfaction and performance becomes legally and
practicably possible and IGEN shall make such effort as in IGEN's sole judgment,
