                                       Part I

         Item 1.  Business
                                      OVERVIEW

              Cambridge Biotech Corporation ("CBC" or the "Company") is in
         the business of developing, manufacturing and marketing products
         for the prevention, detection and treatment of diseases in humans
         and animals.  Its Biopharmaceutical Division creates products
         which stimulate the immune system to control or prevent infectious
         diseases and cancer.  The Diagnostic Division has developed an
         extensive line of diagnostic products for the detection of
         infectious diseases.  

              On July 7, 1994, CBC filed for protection under Chapter 11 of
         the United States Bankruptcy Code and is a debtor in possession
         pursuant to a voluntary petition filed in the United States
         Bankruptcy Court for the district of Massachusetts, Western
         Division, Case No. 94-43054-JFQ.  Since the commencement of the
         Chapter 11 Case, CBC has been aggressively restructuring its
         business and refocusing its business strategy.  CBC has made
         significant progress in developing and implementing its strategy
         of emerging as a refocused, recapitalized Biopharmaceutical
         company.  To that end, CBC has sold off its unprofitable Irish
         subsidiary and other non-essential assets and is negotiating the
         sale of its diagnostics business.  CBC has given considerable
         attention to resolving a class action lawsuit filed against the
         Company and several of its former officers, and has successfully
         negotiated a settlement with the plaintiffs which has been
         preliminarily approved by the District Court.  In order to
         maximize the value of the diagnostics business, CBC devoted
         significant effort to litigation commenced by Institut Pasteur and
         Genetic Systems Corporation alleging patent infringement with
         respect to CBC's commercialization of diagnostic tests for the
         HIV-2 strain of the AIDS virus and CBC's Western Blot confirmatory
         test for HIV-1.  This litigation has now been favorably
         adjudicated by the Bankruptcy Court.  

              In April 1995, CBC engaged Dr. Alison Taunton-Rigby as its
         new President and Chief Executive Officer.  Jeffrey T. Beaver
         became Chairman of the Board of Directors.  Under Dr. Taunton-
         Rigby's leadership, CBC has developed and begun to implement a new
         strategic business plan.  This plan contemplates sale of the
         Diagnostic Division and the focusing of the Company after its
         emergence from Chapter 11 on the business of the Biopharmaceutical
         Division.  The Company is currently actively negotiating with
         potential buyers for the sale of the Diagnostic Division. Any sale
         is subject to the approval of the Bankruptcy Court.





                             BIOPHARMACEUTICAL DIVISION

              The Company's Biopharmaceutical Division creates products
         which stimulate the immune system to control or prevent infectious
         diseases and cancer.  The Company's first vaccine, for feline
         leukemia virus, has been sold commercially since 1989.  The
         Company is currently developing human vaccines for streptococcal
         pneumonia, malaria and tick-borne diseases, and animal vaccines
         for Lyme disease and bovine mastitis.  Company scientists have
         purified a family of compounds that are potent immune stimulants
         which can be used as adjuvants.  Adjuvants are important
         components of vaccines that, in conjunction with the antigen (the
         disease-related component), stimulate the immune system to produce
         a protective response.  One of these adjuvants, QS-21, is being
         formulated with various human vaccines and has been tested in over
         500 people.  The Company is commercializing this family of
         adjuvants under the tradename StimulonTM, both by licensing other
         pharmaceutical companies to incorporate StimulonTM adjuvants into
         their vaccines and by using them in the Company's own vaccine
         development programs.

              The worldwide vaccine market was estimated in 1993 by Frost &
         Sullivan to total approximately $2.5 billion per year, of which
         50% is in North America and almost 30% in Europe.  Frost &
         Sullivan project that the total worldwide vaccine market will
         exceed $5 billion by 1999.  Vaccines are widely considered to be a
         cost-effective method of delivering significant public health
         benefits, and government and industry are committing substantial
         resources to developing new vaccines and other immunotherapy
         products for use in the prevention and treatment of disease.  The
         advent of biotechnology has enabled scientists to develop a new
         generation of vaccines, known as subunit or recombinant vaccines.
         Since these new recombinant vaccines contain only immunologically
         important portions of the infectious agent, they are often safer
         than classical vaccines, but sometimes less effective in
         stimulating adequate immune responses.  Adjuvants heighten the
         immune response generated by vaccination.  New, more effective
         adjuvants such as QS-21 are often necessary to make the new
         generation of recombinant vaccines effective.

              The Company conducts research and development in the adjuvant
         field and maintains its own vaccine and immunotherapy product
         development programs.  The Company developed the first recombinant
         vaccine against a tumor-causing virus in mammals, a vaccine
         against feline leukemia virus (FeLV).  As part of the FeLV vaccine
         product development effort, it developed a new family of
         adjuvants.  QS-21 is part of the StimulonTM family, and is the
         basis for much of the Company's vaccine-related activities.   

              The Company has licensed other vaccine manufacturers to use
         QS-21 and other StimulonTM adjuvants in their own vaccine programs,
         including SmithKline Beecham p.l.c., Pasteur Merieux Serums &
         Vaccins S.A., Wyeth-Lederle Vaccines and Pediatrics, Genentech,
         Inc., NABI, and Progenics Pharmaceuticals, Inc.  These licensees
         have completed nine clinical trials thus far.  The Company has
         received substantial license fees and anticipates that it will
         receive additional license fees and royalties, as well as revenues
         from the manufacturing and supply of adjuvant.

              In the human health field, the Company is developing a
         vaccine to prevent pneumococcal infections in the elderly
         population.  It is also developing a combination vaccine for tick-
         borne diseases to protect against human Lyme disease and human
         granulocytic ehrlichiosis ("HGE"), a disease which has only
         recently been identified as a significant human health concern.
         The Company believes that it was the first to successfully
         cultivate the HGE organism in tissue culture, and has filed patent
         applications on infected cell lines, methods of growing the
         organism, and vaccine antigens and diagnostic reagents derived
         from the cell lines.  In addition, CBC is working with the World
         Health Organization to develop two vaccines against malaria, and
         with outside collaborators on vaccines for the prevention or
         treatment of other infectious diseases and cancer.  

              In the animal health area, CBC is completing development of a
         canine Lyme Disease vaccine and is also developing a vaccine
         against bovine mastitis, the leading healthcare concern in the
         dairy industry.  CBC also manufactures an FeLV vaccine.

              The Company has experience manufacturing clinical
         pharmaceutical products and animal vaccines, through manufacturing
         the FeLV vaccine and QS-21.  The Company intends to manufacture
         certain of the products which it develops.

         The Company's Business Strategy

              The StimulonTM Adjuvant.  Continued success of the StimulonTM
         adjuvant program is considered central to the future success of
         the Company.  It has licensed major vaccine manufacturers to
         incorporate QS-21 and the other StimulonTM adjuvants into their
         own vaccine programs.  The Company intends to devote considerable
         effort to monitoring the licensees' diligence in pursuing their
         development programs, conducting experiments and sharing technical
         advances believed likely to further these programs, optimizing
         adjuvant manufacturing processes, and conducting additional
         adjuvant development.  The Company expects to grant new licenses
         for the adjuvant in applications which will not conflict with its
         own vaccine development programs.  It will continue to pursue
         opportunities, such as the malaria vaccine program which, if
         successful, could create a substantial market for bulk adjuvant. 

              Human Vaccine Development.  The Company intends to focus its
         own product development efforts on emerging diseases, such as Lyme
         disease and HGE, and emerging problems, such as the pressing need
         for an improved pneumococcal vaccine.  The Company believes that
         its technical strengths and available resources are best suited to
         taking product from late-stage research through to proof of
         principle in humans.  The Company has demonstrated its product
         development capabilities in its development of the FeLV vaccine
         and the first recombinant diagnostic test for HIV.  In addition to
         its own development efforts, the Company has established a large
         network of independent academic collaborators to supplement the
         flow of product development opportunities.  The Company expects to
         seek marketing partners for most of its products in this area,
         although it will be alert to opportunities to complete product
         development and even market products directly.  Cancer vaccines
         may present such an opportunity.

              Animal Health.  Historically, animal health was a focus of
         CBC and it continues to present an important opportunity.
         However, the Company believes that the advantages of animal
         health--the ability to carry on development in the host animal and
         the relatively rapid regulatory process--tend to be offset by
         smaller market sizes and profit potential.  Therefore, it will
         only devote its development resources to animal health if the
         product opportunity addresses a large market with attractive
         margins (such as bovine mastitis), or if the development is funded
         by a partner (such as with its FeLV vaccine) or if the opportunity
         in animal health is a by-product of a human program (as may be the
         case with HGE).


         Products and Programs

              Licensing for Infectious Diseases and Cancer.  The Company
         has licensed a number of other companies, including three of the
         world's four leading vaccine manufacturers, to use StimulonTM
         adjuvants in a variety of infectious disease vaccines.  At the
         same time, the Company reserved its own right to use StimulonTM
         adjuvants to develop selected vaccines.

              The licensees have completed a number of clinical trials and
         have development programs underway for a significant number of
         diseases, as summarized in the tables below:

         a.   Multiple partners and/or diffrent antigens

              The license agreements with strategic partners typically
         provide for the payment of initial license fees, additional fees
         either annually or based on the licensee's achievement of
         development milestones, and royalties on product sales.  In
         addition, the Company will be the sole supplier of QS-21 used in
         the vaccines.  Through December 1995, the Company has received
         over $15 million in license fees.
          
         The principal licensees are:

                   SmithKline Beecham has licensed QS-21 for a number of
              different applications, including influenza, herpes,
              hepatitis, and Lyme disease.  The world's leading
              manufacturer of Hepatitis B vaccine, SmithKline is
              aggressively marketing its existing portfolio of vaccines,
              while developing new and improved products. SmithKline has
              completed a number of Phase I clinical trials of potential
              vaccines containing QS-21 and is also investigating the use
              of combinations of different adjuvants.  The Company believes
              that SmithKline will initiate additional trials in 1996, and
              has QS-21 in its pre-clinical development programs for
              several vaccines.

                   Pasteur Merieux Serums & Vaccins has licensed QS-21 for
              use in its influenza and HIV vaccine programs.  The world's
              leading manufacturer of influenza vaccines, Pasteur Merieux
              has since 1990 increased its presence in North America
              through its acquisition of Connaught Laboratories.  Pasteur
              Merieux has completed a low dose QS-21 Phase I clinical trial
              for influenza.  Pasteur Merieux expects to initiate a high
              dose QS-21 influenza Phase I trial in 1996 and also plans to
              initiate two HIV vaccine Phase I trials in 1996 incorporating
              QS-21, using two different antigen approaches.

                   Wyeth-Lederle Vaccines and Pediatrics licensed QS-21 in
              1992 for use in five vaccines.  Wyeth-Lederle, formed as a
              result of the acquisition of American Cyanamid by American
              Home Products, is a leader in pediatric vaccines.  Wyeth-
              Lederle initiated its first Phase I clinical trial using QS-
              21 in 1995, and expects to continue trials in 1996.

                   Progenics Pharmaceuticals, Inc. licensed QS-21 in 1995
              for use in therapeutic vaccines for cancer.  Progenics' most
              advanced program involves the use of QS-21 with a ganglioside
              preparation to treat melanoma.  Phase I/II clinical trials of
              this vaccine, which was initially developed by physicians at
              Memorial Hospital for Cancer and Related Diseases ("Memorial
              Sloan Kettering"), were completed in 1993.  The product is
              expected to enter pivotal human trials in 1996 under the
              aegis of the Collaborative Oncology Groups.   Other potential
              antigens have been tested in Phase I/II clinical trials.  One
              Phase I/II trial is still ongoing and will be completed in
              the fourth quarter of 1996.  Memorial Sloan Kettering has
              licensed technology to Progenics, and the Company has
              licensed Progenics to use QS-21 in exchange for a license
              fee, an equity interest in Progenics, and royalties.

              In addition, the Company has granted two other licenses to
         use QS-21 for infectious diseases.  Genentech has licensed QS-21
         for use in its HIV-1 vaccine program.  Genentech has conducted
         Phase I clinical trials in healthy volunteers with a vaccine
         formulated with QS-21, under the auspices of the National
         Institutes of Health ("NIH").  This trial was expanded in 1994
         after improved neutralizing antibody responses were observed in
         volunteers receiving vaccines containing QS-21.  Genentech hopes
         to initiate two additional studies in 1996, one with infants born
         to HIV-positive mothers and another evaluating a low-dose vaccine
         formulation in normal volunteers.  The NIH is sponsoring both of
         these trials.  However, the NIH has not agreed to fund large-scale
         efficacy trials of the Genentech vaccine, or any HIV vaccine, and
         has sharply limited the progress of HIV vaccines to pivotal
         clinical trials.  The Company understands that Genentech is
         currently re-evaluating its HIV vaccine program.

              NABI has licensed QS-21 for use in production of
         immunoglobulin for prevention and treatment of gram-negative and
         gram-positive bacterial infections.  NABI is currently evaluating
         its conjugate vaccines in clinical trials without using adjuvants
         and is evaluating QS-21 in preclinical studies.  NABI is also
         testing the efficacy of its immunogloblin in a target population
         of children with cystic fibrosis, and is testing its Staphyloccal
         vaccine in other clinical trials.  The Company is uncertain if or
         when NABI will commence clinical trials using QS-21.


         Manufacturing and Scale-Up

              As part of each Stimulon_ licensing agreement, the Company
         has retained the right to be the exclusive QS-21 supplier.  The
         QS-21 license agreements stipulate the supply prices, within
         certain ranges.  The Company believes that it will be able to
         manufacture adjuvant at a cost which will yield reasonable
         manufacturing margins.  Pursuant to the license agreements, the
         Company will also receive royalties on its licensees' product
         sales.

              The Company currently manufactures QS-21 for commercial
         animal health use and for use in early stage human clinical
         trials.  The Company has successfully scaled the QS-21
         manufacturing process to a point where the average batch size is
         sufficient for approximately 100,000 vaccine doses.  Product for
         use in Phase III clinical trials has been produced on a contract
         basis at BASF BioResearch Corporation, in Worcester, MA.  The
         Company plans to begin manufacturing additional product for use in
         Phase III clinical trials in its Worcester facility.  The Company
         is currently scaling the process to produce a batch size suitable
         for commercial production of between 500,000 and 2,000,000 doses,
         and expects that its process will be commercially feasible.  

              QS-21 is currently classified by the FDA as a constituent
         material used in drug preparation.  As a result, the FDA does not
         require licensure of facilities used in its manufacture.  The
         Company believes that classification as a constituent material
         affords it the flexibility to postpone investment in commercial
         manufacturing facilities until after the safety and effectiveness
         of QS-21 have been demonstrated in Phase III trials.  By that
         time, the Company expects to be in a position to reasonably
         project the required plant capacity.  Product for early
         commercialization may be produced on a contract basis.

              Adjuvant Research and Development.  While QS-21 is the first
         adjuvant developed by the Company, research and development is
         proceeding to identify and create other adjuvants and to develop
         new methods of using adjuvants.  The Company currently has in
         development QS-7, another molecule isolated from the Quillaja
         saponaria bark extract.  QS-7 appears to have similar
         immunogenicity and a better toxicological profile in animals than
         QS-21, which may make it more suitable for use in certain
         vaccines.  The Company and its licensees may initiate human pre-
         clinical testing with QS-7 in 1996.

              The Company maintains an active research program expanding
         the use of QS-21 and other saponins.  Company scientists are
         working internally and in conjunction with outside collaborators.
         Significant efforts are underway in the following areas:

              Trans-mucosal Delivery of Vaccines.  If vaccines could be
         administered across the mucosa--e.g., nasally or vaginally--the
         ease of use would increase compliance and the vaccine may offer
         improved protection against pathogens which infect via this route-
         -for example, sexually transmitted diseases and certain
         respiratory diseases.  In addition to their adjuvant properties,
         StimulonTM adjuvants alter the permeability of mucosal membranes,
         and this quality may enable such vaccines to be developed.  The
         Company has demonstrated in a mouse model the ability of a vaccine
         containing QS-21, delivered nasally, to induce both antibody and
         cell-mediated immune responses.  The Company is working with
         academic collaborators to develop this approach.

              Nucleic Acid ("Naked DNA") Vaccines.  An intriguing new
         vaccine technology, known as "Naked DNA," involves injecting DNA
         sequences directly into muscle tissue.  The muscle cells then take
         up the DNA and produce the encoded protein.  The Company is
         collaborating with an academic researcher developing this
         technology to determine if QS-21 can improve the effectiveness of
         such vaccines.

              "Tuning" of Vaccines.  Some vaccines derive their
         effectiveness primarily from the induction of an antibody
         response, while others depend primarily on a cell-mediated
         response.  The Company believes that it is desirable to "tune"
         some vaccine formulations to achieve the most effective immune
         response to the target disease.  One such program currently
         underway is a collaboration with the Immune Response Corporation
         to test the hypothesis of the late Jonas Salk that an effective
         HIV vaccine must be tuned to induce a cell-mediated response with
         little or no antibody response.  Salk's hypothesis is that a low
         antigen dose plus an adjuvant that promotes cell mediated immune
         response is the approach to use to elicit an effective immune
         response to HIV. 

               The Company and its collaborators are also conducting
         research aimed at better understanding how QS-21 and other
         adjuvants work, testing adjuvant and carrier combinations, and
         discovering new adjuvants.

         Human Vaccine Programs

              In addition to its licensees' programs, the Company is
         developing its own vaccines for human use as set forth below:

              Streptococcus Pneumoniae Vaccine for the Elderly.
         Pneumococcal infections remain a major cause of death in the
         world.  Increasing antibiotic resistance of certain pneumococcal
         strains has resulted in growing awareness of the importance of
         prevention in controlling these infections.  Various strains of S.
         pneumoniae are responsible for most community-acquired cases of
         pneumonia (500,000 cases per year) and are the second most common
         cause of bacteremia (50,000 cases per year, with 25% mortality).
         S. pneumoniae also causes half of childhood otitis media, the most
         frequent reason (one out of three) for visits to pediatricians. In
         some developing countries, pneumococcal pneumonia kills
         approximately 10% of the children under the age of five, making it
         the single leading cause of death.  Public health officials now
         place a high priority on the development of new pneumococcal
         vaccines, and are considering expanding the population for which
         vaccination would be recommended. 

              There are currently 83 recognized serotypes of pneumococci,
         each with varying geographic and age-group prevalence.  The
         currently available vaccines cover 23 serotypes, which cause 93%
         of United States and European infections.  These vaccines are
         composed of purified capsular polysaccharides, which typically are
         not potent immunogens.  Although approved by the FDA for use in
         adults, these vaccines are not recommended for children under two
         years of age or immune-compromised patients, and are less
         effective in elderly individuals.  Development efforts are
         underway by several companies to improve the immune response in
         children by conjugating the polysaccharides to immunogenic carrier
         proteins. This approach was used in developing the successful Hib
         vaccines.  However, the manufacturing expense and cumulative mass
         of the conjugated components make it very difficult to include all
         23 conjugates.  The companies developing conjugate vaccines have
         therefore chosen to focus on the five to seven strains most
         prevalent in infants.  The resulting vaccines, if successfully
         developed, would likely not be appropriate for immunization of
         adults and the elderly.  It is also likely that these vaccines
         would be too expensive for widespread use in the developing world.

              The Company has been developing a new formulation of a 23-
         valent polysaccharide vaccine incorporating QS-21.  This
         formulation is intended to be more effective in elderly patients
         against most of the 23 serotypes common in the United States and
         Europe.  If this formulation is successful, similar vaccines could
         be developed for other geographic areas using strains prevalent in
         those areas.  The target market would be the 12 million Americans
         over age 65, a market which could be expanded to include persons
         over age 50.

              The Company's technical approach to the development of a
         pneumococcal vaccine for the elderly is to formulate the existing
         23-valent capsular polysaccharide vaccine with QS-21 or QS-7.
         Research in various mouse models indicates that such a formulation
         could significantly improve the existing vaccine.  For instance,
         many polysaccharides to which mice do not typically respond induce
         antibody production when mixed with QS-21.  The effect may make
         use of a lower antigen dose feasible, which could make the vaccine
         less expensive and also reduce side effects.  QS-21 also appears
         to cause an antibody isotype class switch which may make the
         immune response more effective.  Finally, mice re-vaccinated with
         the prototype QS-21 vaccine experience a booster effect for many
         strains, a response not seen with existing vaccines.  This effect
         may enable the administration of periodic booster shots to
         maintain immunity levels.  The Company is working with the
         National Institutes of Health ("NIH") to initiate Phase I clinical
         trials.  These trials, expected to commence in 1996, are intended
         to determine the safety of the formulation and to test whether the
         addition of QS-21 increases the immunogenicity of the vaccine or
         reduces the amount of antigen required to produce an effective
         immune response.  If the Phase I results are positive, the Company
         intends to proceed with additional clinical trials required for
         regulatory approval.

              Based on QS-21's ability to make mucosal membranes more
         permeable and elicit an immune response, the Company intends to
         investigate the development of a nasal pneumococcal vaccine.  This
         approach may have advantages in ease of administration and for
         increasing protection in the respiratory mucosa, which is the
         typical route of infection for the pneumococcus. 

              Tick-borne Disease Vaccine.  Tick bites can cause a variety
         of diseases, including Rocky Mountain Spotted Fever, Babesiosis
         and Lyme disease.  Lyme disease was first discovered in 1969, and
         its cause, bites by ticks infected with Borrelia burgdorferi, was
         not identified until 1981.  According to the Centers for Disease
         Control and Prevention ("CDC"), Lyme disease is now the leading
         tick-borne infectious disease in the United States, with over
         40,000 reported cases, including cases in all 50 states.  In 1991
         scientists reported the discovery of a newly recognized disease,
         human granulocytic ehrlichiosis (HGE), caused by a microorganism
         in the genus Ehrlichia transmitted by the bite of the same tick
         that carries Lyme disease.  HGE's flu-like symptoms include fever,
         headache and muscular aches, as well as joint pain, nausea,
         vomiting and cough.  HGE is believed to have caused at least four
         deaths in immune-compromised patients.

              Company scientists found the HGE-causing organism in dogs in
         1994 in the course of the efficacy trials of the Company's canine
         Lyme disease vaccine, described below, and traced its source to
         the ticks.  The Company believes that it was the first to
         successfully cultivate the HGE organism in tissue culture.  The
         Company has filed patent applications on infected cell lines, the
         methods of growing the organism, and potential vaccine antigens
         and diagnostic reagents derived from the cell lines. 

              The Company has been working with the CDC to develop a blood
         test to be used in epidemiological surveys that will determine how
         widespread the disease may be.  Prior to the Company's development
         of the cell lines, diagnosis of the disease was extremely
         difficult, and impractical for survey purposes.  The Company has
         been conducting additional internal research to better
         characterize the organism and to develop additional vaccine
         antigens and diagnostic reagents, and has recently initiated
         collaborations with leading academic researchers to do work in
         this area.  In the course of the canine Lyme disease vaccine
         program described below, the Company has made progress toward the
         development of a human Lyme disease vaccine.  It believes that a
         combination vaccine could be developed against HGE and human Lyme
         disease.  The Company will also investigate the inclusion of
         Ehrlichia chaffeensis antigens and other tick borne diseases in a
         combination vaccine.  The Company believes that its work in HGE
         may also have applicability for animal health applications.  The
         HGE organism appears to cause illness in dogs.  Once the
         epidemiology is better understood, the Company may seek
         development funding from an animal health partner.

              Malaria Vaccines.  According to estimates in published
         reports, over two billion people reside in malaria-infected areas.
         The yearly incidence of malaria is estimated by the World Health
         Organization at over 300 to 500 million cases, with a death toll
         of 1.5 to 3 million persons.  While anti-malarial drugs have been
         in use for decades, they are expensive and resistant malarial
         strains are becoming increasingly common.  The World Health
         Organization has identified malaria as a priority vaccine target
         in developing countries.  In addition, the Company believes a
         traveler's vaccine presents a significant market in developed
         countries.  The Company has two separate malaria vaccine
         development programs, one partially supported by grants.

              In collaboration with the WHO, the Company has been working
         with the SPF66 antigen, which was developed in Colombia by Dr.
         Manuel Pattaroya.  This antigen has been extensively studied in
         several clinical trials.  Two separate studies showed that SPf66
         vaccines formulated with alum provided protection against malaria
         for 31% of adults and children who received the vaccine.  However,
         a large antigen dose was used in these studies and such a
         formulation is unlikely to be economically feasible.  Based on
         animal studies, the Company believes that formulating SPf66 with
         QS-21 may raise protection levels while reducing the amount of
         antigen required.  The Company has contracted with Dr. Pattaroya
         to conduct malaria challenge studies in Aotus monkeys, and the WHO
         has agreed to fund human trials if these studies show improved
         efficacy.  The Company's principal strategic interest in the
         malaria vaccine is to be the adjuvant supplier for a high volume
         vaccine.

              A second program, in collaboration with the Walter Reed
         Institute for Research ("WRAIR") and supported by a WHO grant, has
         been investigating the use of a different antigen, EBA-175.  This
         antigen is an essential element in the binding of the malaria
         parasite to target red blood cells.  The Company is developing and
         supplying the antigen for further research by WRAIR.  Clinical
         trials would be conducted by WRAIR and WHO.

              Cancer Vaccines.  Cancer is a major health care concern in
         the United States and Europe.  While substantial progress has been
         made treating some cancers with surgery, radiation therapy and
         chemotherapy, those treatments are arduous and often not
         effective. Immunotherapy for the treatment of cancer is showing
         increasing promise, most often in conjunction with traditional
         therapy, although the approach faces substantial technical
         uncertainty.  The potential market for cancer immunotherapy has
         been estimated to be $1-3 billion, with the largest markets in
         breast, colorectal and prostate cancer.

              Cancer is the uncontrolled replication of cells, typically
         initiated by the occurrence of one or more mutations.  The promise
         of cancer immunotherapy lies in the belief that the healthy immune
         system is able in most cases to eliminate cells which, due to
         mutation, appear "foreign."  Cancer results, however, if the
         immune system fails, whether due to its failure to recognize the
         abnormal cells or because the system is simply overwhelmed by the
         number of cancer cells.  Cancer immunotherapy aims to improve the
         immune system's ability to recognize cancerous cells and to
         increase and broaden the immune response.  Studies of cancer
         vaccines in laboratory animals have shown immune stimulation and
         protection from experimentally induced cancer.  Initial human
         trials of certain cancer vaccines shows evidence of the desired
         activation of the immune system.  However, clinical success,
         measured by decreased tumor burden, increased tumor-free
         intervals, or prolonged life, is yet to be fully demonstrated.
         The Company believes that QS-21 can contribute to the
         effectiveness of cancer vaccines by augmenting the immune
         stimulus.

              Much of the cancer vaccine research in the United States is
         performed at academic institutions, the Federal government's
         National Cancer Institute ("NCI"), and small companies. The
         Company has adopted a strategy of supporting selected, promising
         clinical trial efforts. This support may be (i) technical support,
         such as antigen characterization or mouse studies; (ii) supply of
         QS-21 which, because of its apparent ability to induce a cellular
         immune response, is thought to be particularly suited to cancer
         vaccines; or (iii) financial assistance, typically small amounts
         of funding at a critical juncture in development.  In this way,
         the Company hopes to gain valuable clinical experience with QS-21
         and obtain an early look at the safety and efficacy of a wide
         range of different vaccine approaches and antigens.  In addition,
         the Company typically has an opportunity to acquire an interest in
         the project should it be successful, or an opportunity to license
         another manufacturer to use QS-21 in conjunction with that
         vaccine.

              The Company presently is involved in several active programs
         for treating melanoma. The first potential product entered
         clinical trials in 1992, and several more products are expected to
         enter clinical trials in the near future.  The most advanced
         program in which the Company is involved is Progenics' program
         using QS-21 with a ganglioside preparation to treat melanoma.
         This vaccine is expected to enter human trials in 1996 under the
         aegis of the Collaborative Oncology Groups. 

              In recognition of the difficulty of predicting which antigen
         formulations are most promising, the Company has arranged for QS-
         21 to be used in melanoma clinical trials with other types of
         antigens by other collaborators.  In most cases, the decision to
         move to human testing was made by the collaborator after
         preclinical work indicated improved immune response to the
         melanoma vaccine using QS-21.  These studies include:

                   A polyvalent vaccine developed by Dr. Jean-Claude
              Bystryn of the Kaplan Cancer Center of New York University;

                   An anti-idiotype GD2 vaccine developed by Dr. Kenneth
              Foon of the Markey Cancer Center at the University of
              Kentucky; and

                   A peptide designed to induce a cell mediated response
              identified by Dr. Donald Hunt and Dr. Victor Englehart of the
              University of Virginia.

              The Company presently has two different programs underway to
         treat adenocarcinoma. One, in collaboration with Dr. Robert Fenton
         of NCI, is expected to enter the clinic in 1996 with a ras onco
         protein antigen for pancreatic, lung and colon cancer.  Another,
         also scheduled for 1996, will be conducted by Dr. Neal Meropol of
         Roswell Park Cancer Institute using a ras peptide for pancreatic
         cancer.  Finally, another clinical trial began in 1995 in
         collaboration with Dr. Ronald Levy of Stanford University to test
         an anti-idiotype vaccine against B cell lymphoma.

              The Company recently entered into a clinical trials agreement
         with the NCI under which scientists working with NCI will conduct
         research combining QS-21 with a broad range of cancer vaccine
         candidates, with the most promising formulations entering the
         clinic under NCI auspices.  Under the agreement, the Company will
         have the opportunity to negotiate commercial rights to any
         resulting vaccines.  Over 10 other academic collaborations
         relating to cancer are in place, with the research in the
         preclinical phase.


         Animal Vaccine Programs

              The Company has historically devoted considerable resources
         to the development of animal health vaccines.  Its first vaccine
         project, funded by the French animal health company Virbac S.A.,
         resulted in the successful development of a vaccine against FeLV.
         FeLV is a highly contagious and commonly fatal disease of cats.
         The Company's FeLV vaccine was the first recombinant vaccine ever
         developed against a tumor-causing virus in mammals.  An important
         by-product of the program was the discovery and development of QS-
         21.  The Company presently manufactures bulk formulated FeLV
         vaccine for the United States and Australian markets, and supplies
         Virbac with bulk antigen and adjuvant for further manufacture for
         the European market.  The vaccine is the leading FeLV vaccine in
         Europe, and in a recent independent study was found to be the most
         effective of three leading FeLV vaccines on the market.

              The development process for animal vaccines is different from
         that required for human vaccines.  Animal vaccines can be tested
         in the host animal very early in the development process, which
         shortens development time frames.  In addition, the U.S.D.A.
         regulatory process is relatively rapid.  However, many animal
         health applications are characterized by small market sizes and
         low product margins.  Therefore, the Company plans to focus its
         efforts on human vaccines, and intends to develop animal health
         applications only if one of three following criteria is met: (i)
         the product opportunity addresses a large market with attractive
         margins; (ii) the development is funded by a partner; or (iii) the
         product is a by-product of a human vaccine development program.

                                                        progress


              The Company currently has two active animal health vaccine
         development programs:

              Bovine Mastitis Vaccine.  Mastitis is an inflammation of a
         dairy cow's udder caused by infection with Staphylococcus aureus,
         Escheria coli or Streptococcus agalactiae plus other organisms.
         The Company is developing a bivalent vaccine designed to prevent
         both S. aureus and E. coli, which together account for the
         majority of mastitis infections.  The development program is 50%
         funded by Virbac.  The Company has exclusive marketing rights in
         North America; Virbac has exclusive marketing rights in Europe.
         The parties share marketing rights in the rest of the world.  If
         the product is effective, the Company believes it could add a
         streptococcal component in a next-generation vaccine.

              The S. aureus component of the vaccine is based on patented
         anti-adhesion technology.  A single S. aureus protein known as
         fibronectin binding protein is primarily responsible for
         attachment of S. aureus to host tissue and establishment of
         infection.  In the Company's mastitis vaccine program, fibronectin
         binding protein is used as an antigen to induce an antibody
         response to block attachment of the bacterium in the cow's udder.
         Recent field trials have indicated that this formulation, using
         QS-21, is safe and immunogenic, and the Company has commenced
         efficacy trials.  If efficacy is successfully demonstrated, the
         Company expects to seek a partner for additional development
         funding in exchange for North American marketing rights.

              Canine Lyme Disease.  The Company is developing a vaccine
         pursuant to a 1991 agreement with Mallinckrodt Veterinary Inc.
         ("Mallinckrodt") against Lyme disease in dogs. There are
         approximately 50 million dogs in the United States, with perhaps
         one fifth of them living in areas infested with the tick which
         transmits Borrelia burgdorferi, the cause of Lyme disease.  The
         potential market for a canine Lyme disease vaccine may be as much
         as $50 million.  A vaccine introduced by another company in 1991
         was well-received in its first year, but sales have decreased
         since then.  There have been published reports raising questions
         concerning that vaccine's safety and efficacy.

              During 1993-94, the Company conducted efficacy trials on its
         canine Lyme disease vaccine using a protocol approved by the USDA.
         The studies showed that use of the Company's vaccine resulted in
         protection from infection in 79% of the dogs, and protection from
         symptoms in 89% of the dogs.  Data from this trial, which included
         injection site reaction and fever score index in addition to
         efficacy data, was submitted to the United States Department of
         Agriculture ("USDA"), which reviewed the data in support of
         licensure and found the outcome to be satisfactory.  The vaccine
         incorporates two outer surface proteins of Borrelia and QS-21, a
         formulation which the Company believes offers better protection
         against multiple strains of the pathogen.  A patent is pending on
         this formulation.

              In 1994, the Company manufactured several bulk lots of canine
         Lyme vaccine to the same final specifications and, following QC
         release, shipped these lots to Mallinckrodt for further
         manufacture in their facilities to final vialed product.
         Mallinckrodt conducted a USDA approved field study using this
         final product as part of the required licensing process. The
         Company has been informed by Mallinckrodt that adverse reactions
         to the final product were observed following administration of the
         vaccine to dogs and that the rates of reaction were
         unsatisfactory.  The Company has not been able to duplicate these
         observations, and the cause of the reactions in the Mallinckrodt
         study has not been determined.  Subsequently, the Company has
         manufactured additional lots of bulk vaccine, and Mallinckrodt has
         completed manufacture of final vialed product.  Mallinckrodt is in
         the process of conducting an additional field safety study.  The
         Company is unable to predict the outcome of these studies.

              Should a canine Lyme vaccine be successfully developed, under
         the Mallinckrodt agreement, the Company will supply Mallinckrodt
         with bulk formulated vaccine, which Mallinckrodt will then fill,
         finish, and distribute.  The Company will be paid a supply price
         for the vaccine and receive a royalty on Mallinckrodt's sales.


         Other Programs

              Drug Delivery.  The Company is developing a drug delivery
         technology which is an outgrowth of the adjuvant development
         program.  In characterizing the properties of QS-21, CBC
         discovered that QS-21 could enhance permeability of mucosal
         membranes allowing antigens and other biomolecules to pass through
         this barrier.  The Company recognized the potential to use this
         feature to deliver drugs, and modified QS-21 so as to retain the
         permeation-enhancing characteristics while eliminating the
         adjuvant properties.  The resulting molecule, known as DS-1, has
         been successfully used in animals to deliver by nasal drops a
         variety of drugs, including gentamicin, insulin and growth
         hormone.  The Company intends to conduct further bio-availability
         and toxicology studies, including a human safety and tolerance
         trial, to define further the potential of DS-1.  The Company
         believes it is important to bring DS-1 into early human testing to
         assess its commercial potential.  The Company plans to
         commercialize DS-1 through companies that specialize in drug
         delivery technology. 

              Mycobacterium avium Vaccine.  The Company is in the early
         research phase of a vaccine development project against
         Mycobacterium avium.  The project is funded by a grant 
         from the NIH.  M. avium poses an increasing risk to immune-
         compromised patients, particularly AIDS patients, among whom the
         infection rate approaches 50%, with the median survival rate of
         infected patients reduced by 60%.  M. avium is related to
         Mycobacterium tuberculosis, a disease once believed to be under
         control but now considered by the WHO to be a global health
         emergency.  The Company believes that its M. avium efforts will
         enable it to become involved in tuberculosis collaborations should
         appropriate opportunities arise.  Two of the Company's current QS-
         21 collaborators are now working in the area of tuberculosis.

              Osteoporosis.  The Company has entered into a joint venture
         to pursue the use of growth hormone releasing factor ("GRF") to
         treat osteoporosis and related diseases with OT Company, a
         principal of which patented the use of GRF to treat osteoporosis,
         and BioNebraska, Inc., which developed a proprietary, commercially
         viable method of manufacturing GRF.  The difficulty and cost of
         manufacturing GRF has stymied previous efforts to use GRF
         therapeutically.  The joint venture commenced a pilot clinical
         study in late 1994, which has not been completed.  An estimated 20
         million women in the United States suffer from osteoporosis, and
         the cost of care is estimated to be greater than $10 billion. 

              Academic Collaborations.  The Company has entered into over
         50 collaborations with academic, government and corporate
         researchers in which the Company supplies adjuvant to the
         researchers for use in vaccine research programs.  Included among
         the diseases in research are cryptosporidiosis, helicobacter,
         toxoplasmosis, tuberculosis and autoimmune diseases.  These
         collaborations have given Company scientists a window to important
         early-stage research, as well as an opportunity to negotiate for
         commercial rights to any resulting products.  The Company intends
         to continue these collaborative efforts and believes these
         collaborations will play an important role in expanding its
         research base and providing development opportunities in the
         future.





                                 DIAGNOSTIC DIVISION

              The Company's Diagnostic Division has developed a line of
         screening and confirmatory diagnostic products for retroviruses
         and other infectious diseases.  The sale of diagnostic products
         represented approximately 63% and 72% of the Company's total
         revenues in 1995 and 1994, respectively.  The Company contemplates
         the sale of the Diagnostic Division and focusing on the business
         of the Biopharmaceutical Division after emergence from Chapter 11.
         The Company is currently actively negotiating with potential
         buyers for the sale of the Diagnostic Division.  Any sale is
         subject to the approval of the Bankruptcy Court. 

              The Company's diagnostic products utilize one of two formats:

                   Enzyme immunoassays ("EIA"), which utilize specific
              enzymes linked to specific antibodies or antigens.  These
              enzymes produce a color change when exposed to a sample
              containing the corresponding specific antigen or antibody,
              and this color change can be read either visually or using a
              specialized instrument;

                   Western blot assays, which are prepared by using an
              electric field to separate multiple antigens of an infectious
              organism.  The separated antigens are transferred, or blotted
              onto a strip of nitrocellulose paper.  When the strip is
              incubated with a serum or plasma sample, specific antibodies
              in the sample, if present, will bind to the corresponding
              specific antigen.  The presence of bound specific antibodies
              can be detected with a color development reagent and visually
              observed.

              The diagnostic products manufactured by the Company that are
         currently on the market include those in the following table.

         Retroviral Products

              Overview of AIDS.  AIDS is a major worldwide health problem.
         In 1992, the World Health Organization estimated that eight to ten
         million adults and one million children worldwide were infected
         with HIV-1, the causative agent of AIDS.

              The current method for the diagnosis of AIDS includes testing
         for the presence of antibodies specific for HIV-1 in a blood
         sample.  A positive test result indicates that the individual has
         been previously exposed to the virus.  Typically, a blood sample
         will initially be tested using a relatively simple inexpensive
         test, such as an EIA, which can provide results within a few
         hours.  This is commonly referred to as a screening test.  If a
         sample tests positive on a screening test, a more specific and
         expensive test, typically a Western blot assay, is performed to
         confirm the screening test result.

              In addition to HIV-1, several other retroviruses have been
         isolated and identified as clinically important infectious agents.
         These include HTLV-I and HTLV-II, and HIV-2.  In the United States
         blood banks now routinely screen all blood not only for HIV-1 but
         also for HIV-2 and HTLV-I.  HTLV-I, which is endemic to Japan and
         certain areas of the Caribbean, is associated with certain
         neurological disorders and with a form of T-cell leukemia.
         Exposure to HIV-2, a virus similar to HIV-1, can also cause AIDS.
         Although specific disease association with HTLV-II has not been
         firmly established, HIV-1 infected individuals who are also
         infected with HTLV-II may develop clinical symptoms and AIDS more
         rapidly than those infected with HIV-1 alone.
         
              Screening Tests.  Screening tests for retroviruses are
         typically used by blood donor centers, hospitals, public health
         laboratories and other laboratories that conduct routine screening
         of blood.  In 1991, the Company received an FDA license for
         Recombigen_ HIV-1 (env & gag) EIA to detect the presence of HIV-1
         antibodies.  In 1995, the Company received an FDA product license
         for its HTLV-I (rp21e-enhanced) assay, an improved sensitivity
         blood screening test.

              The Company has filed Product License Applications ("PLA")
         with the FDA for two new EIA tests to simultaneously detect
         antibodies to HIV-1 and HIV-2.  These tests have been approved for
         use in selected countries in Europe.  

              Confirmatory Tests.  The Company has products and expertise
         in viral lysate technology, especially as applied to Western blot
         confirmatory testing.  In 1987 the Company introduced the first
         confirmatory test for HIV-1 antibodies to be licensed by the FDA.
         A Western blot which confirms and detects HTLV-I or HTLV-II
         antibodies is in clinical use in selected countries in Europe, as
         is an HIV-2 Western blot.  The Company has completed clinical
         trials for these tests and has filed PLAs with the FDA.  The
         Company has also filed an amendment to its license for the HIV-1
         Western Blot product to permit its use as a confirmatory test for
         a urine-based screening test.


         Other Diagnostic Products

              The Company offers a range of other diagnostic products for
         infectious diseases. Certain of these products, such as those for
         Lyme disease and various gastrointestinal diseases, were developed
         internally.  In other cases, the Company has acquired distribution
         rights by acquisition, licensing, or private label manufacturing
         arrangements.

              Lyme Disease.  Lyme disease has become a major clinical
         disease and is one of the most common tick-borne illnesses
         recognized in the United States.  This multi system infection can
         affect the skin, heart, joints and nervous system.  The causative
         agent of Lyme disease is Borrelia burgdorferi, a spirochete.

              The Company has developed three tests to detect the presence
         of antibodies to Borrelia burdorferi: an EIA test, a Western blot
         assay to detect the presence of antibodies of the IgM class
         (designed to detect early infection), and a Western blot assay to
         detect antibodies of the IgG class (designed to detect later
         stages of the disease).  The Western blot assays are currently
         manufactured for the Company by its former subsidiary in Galway
         with the Company maintaining the right to resume manufacture of
         the product.

              Gastrointestinal Disease Diagnostic Products.  The Company
         manufactures and markets two tests for adenovirus and one for
         rotavirus, two highly contagious gastrointestinal diseases which
         often afflict infants and elderly adults.  The Company's product
         to detect rotavirus (Rotaclone_ EIA) has been manufactured and
         marketed since 1986.  The Company's Adenoclone_ EIA test, which
         detects the presence of adenovirus, is manufactured and marketed
         in two versions: a version designed to detect the presence of any
         of the adenovirus strains and a second version specifically
         designed to detect the presence of two of the most common strains
         of adenovirus, types 40 and 41.  The Adenoclone_ tests were the
         first adenovirus tests to be approved for marketing by the FDA.

              The Company also markets an EIA test to detect infection by
         Clostridium difficile, the leading cause of antibiotic-associated
         diarrhea.  The Company's test is unique in that it detects both
         toxins produced by the Clostridium difficile bacteria.  An
         improved test for Clostridium difficile, featuring simplified
         operation, was introduced in April 1994. 


         Sales and Marketing

              The Company markets its products directly and through
         distributors.  The Company's principal direct sales customers
         include hospitals, reference laboratories, and public health
         laboratories.  The principal distributor in North America and
         Europe for the Company's screening products is Ortho Diagnostic
         Systems, Inc. ("Ortho").  In addition, the Company utilizes local
         distributors in Europe and Asia and other distributors to reach
         targeted markets.
              
              Ortho is the Company's principal distributor in North America
         and Europe for retroviral products, which include both screening
         and confirmatory tests.  Ortho's principal customers include blood
         banks and hospital and reference laboratories.  Ortho distributes
         the Company's Recombigen_ HIV-1 (env & gag) EIA test and HIV-1
         Western blot.  The Company has licensed Ortho and Chiron
         Corporation ("Chiron") to manufacture, use, and sell the HTLV-I
         (rp21e-enhanced) EIA product, which license is exclusive (with
         exceptions for pre-existing agreements and distribution in certain
         configurations) in the United States, Canada, and certain European
         countries.  Ortho/Chiron has not commenced manufacturing the
         product at its facility as anticipated under the license
         agreement.  The Company is continuing to supply product to Ortho
         from its Rockville facility.  The license agreement provides that
         after manufacturing is transferred to Ortho, the Company will
         supply Ortho with certain critical raw materials and receive a
         royalty on sales, and Ortho will supply the Company with HTLV
         (rp21e-enhanced) EIA product for distribution into the Company's
         markets.  Sales to Ortho in 1995 represented 30% of the Company's
         revenues.

              The Company also has some specialized marketing arrangements.
         The Company supplies retroviral products and reagents to Behring
         Diagnostics ("Behring"), which are sold to customers using
         Behring's proprietary instrumentation.  Sanofi Diagnostics Pasteur
         ("Pasteur") and its affiliates distribute the Company's Lyme
         disease test under private label.


         Manufacturing

              The Company currently manufactures its Western blot products
         and conducts virus production and purification in its Rockville
         facility which has been licensed by the FDA to manufacture certain
         products.  Specialty tests, such as Recombigen_, and recombinant
         antigens which are used in diagnostic tests and vaccines, are
         manufactured in the Worcester facility, which has been licensed
         for the manufacture of certain products by the FDA, the USDA, and
         the European Economic Community (Agricultural Division).  The
         Company must amend its FDA facility license to manufacture certain
         new products.

              The Company manufactures most of the critical components of
         its products but obtains certain raw materials from outside
         vendors.  In certain cases, these materials are obtained from a
         single source; most of the single source suppliers supply only one
         component and are domestic companies with substantial
         manufacturing experience.  The Company endeavors to ensure a
         continuous supply of raw materials through inventory practices,
         vendor audits, and multiple sourcing when feasible.  The Company
         keeps on hand large quantities of certain components used in its
         diagnostic products, which are manufactured utilizing specialized
         equipment in regulated facilities in large lot sizes to take
         advantage of economies of scale.


         Other Sources of Revenue

              The Company also derives revenue from patent licensing, from
         its clinical reference laboratory, and from government grants.

              The Company has granted sublicenses to the patent covering
         gp120, the envelope protein of HIV-1, to over a dozen different
         companies in return for license fees, royalties, and/or
         technology.  At least three of these licensees, Ortho, Biochem
         ImmunoSystems, and Repligen marketed gp120 products and paid
         royalties on their sales during 1995.  The Company has also
         sublicensed Pasteur, Ortho and Chiron, International Murex
         Corporation, and Abbott Laboratories to practice the gp61 patent
         on the envelope protein of HTLV-I.  In addition, the Company has
         sublicensed the patents covering agglutinographic slide technology
         to Hoffman-LaRoche for testing for drugs of abuse.  The Company
         may grant licenses to other technologies in its portfolio in
         return for license fees, royalties and/or technology, although
         there can be no assurance that any licensing attempts will be
         successful or that the revenue derived therefrom will be
         significant.

              The Company operates a clinical reference laboratory in
         Worcester which is licensed by the College of American
         Pathologists ("CAP").  The reference laboratory offers complete
         retroviral antibody testing services and provides technical
         support function for the customers of the Company's products.  The
         license from CAP expires in May 1996.  The Company does not intend
         to continue operating the reference laboratory.

              The Company is from time to time awarded grants from NIH.


                           PATENTS AND PROPRIETARY RIGHTS

              The Company has pursued a policy of obtaining patent
         protection both in the United States and in selected foreign
         countries for patentable subject matter in its proprietary
         technologies.  The Company has filed or has rights to more than 20
         U.S. patents and patent applications and their foreign
         counterparts.  If U.S. patents issue on the Company's various
         applications, each patent may be expected to have a life of 17
         years from the date of issue or, if filed after June 8, 1995, 20
         years from the date the application was filed.  The Company also
         relies on trade secrets, proprietary know-how, and continuing
         technical innovation to develop and maintain its competitive
         position.

              The Company's future success will depend, in part, upon its
         ability to develop patentable products and technologies and obtain
         patent protection for its products and technologies both in the
         United States and Europe.  There can be no assurance that patent
         applications owned or licensed by the Company will issue as
         patents, that patent protection will be secured for any particular
         technology, or that, if issued, such patents will be valid, or
         that they will provide the Company with meaningful protection
         against competitors with a competitive advantage.  There can be no
         assurance that the patents will not be challenged or designed
         around by others.  Proceedings brought against the Company's
         patents could expose it to significant expense and the risk of
         adverse determinations.

              The Company has engaged in negotiations to obtain licenses
         from Ciba Geigy, S.A., Organon Teknika, N.V., and Hybritech, Inc.,
         now owned by Beckman Instruments, each of whom has asserted that
         its patent covers certain of the Company's diagnostic products,
         including, in one instance, the Company's Western blot products.
         While the Company believes it can resolve these matters on
         reasonable terms, there can be no assurance that one or more of
         these companies will not insist on terms unfavorable to the
         Company, such as substantial retroactive royalties, or that the
         Company will be able to reformulate the products.

              Set forth below is a chart which lists U.S. patents owned or
         exclusively licensed by the Company.

         Biopharm Patents and Licenses

              QS-21 and other Adjuvants.  The Company received U.S. Patent
         No. 5,057,540 in 1991, covering purified QS-21, QS-7 and the other
         principal fractions of Q. saponaria and methods of their use in
         vaccines.  It believes that the standard of purity specified in
         the patent for the saponin fractions is necessary to achieve a
         safety profile acceptable for human use. CSL International ACN
         ("CSL") controls certain patents and patent applications covering
         ISCOMS (immune stimulating complexes) prepared from crude saponin
         fractions, lipids and various antigens.  The Company believes that
         its products do not infringe CSL's U.S. or European patents due to
         process differences and formulation techniques which avoid ISCOM
         formation, although the issue is less clear in Europe.  In the
         event patents do issue to CSL or other parties which dominate QS-
         21, there can be no assurance that the Company will be able to
         obtain licenses or obtain such licenses on favorable terms.  

              Human Granulocytic Ehrlichiosis.  The Company believes that
         it was the first to successfully cultivate the HGE organism in
         tissue culture.  The Company has filed patent applications on
         infected cell lines, the methods of growing the organism, and
         potential vaccine antigens and diagnostic reagents derived from
         the cell lines.  Other researchers in the field of HGE have filed
         patent applications that might conflict with the Company's patent
         applications.  There can be no assurance that any of its patent
         applications will issue.


              Lyme Disease.  The Company has filed a patent application on
         its vaccine formulation of using both the A and the B outer
         surface proteins and QS-21; animal data indicates this formulation
         induces group-specific immune responses (important to protection
         against multiple Borrelia strains) significantly better than
         vaccines containing only one or two of these components.  There
         are several patents pending in the United States and in Europe
         which, if issued in their current form, may dominate the Company's
         Lyme vaccine.  The Company believes that it is unlikely that any
         dominant claims will issue because of the extensive prior art, but
         there can be no assurance that the Company's position is correct
         and, if dominating patents do issue, there can be no assurance
         that it will be able to obtain the necessary licenses or obtain
         such licenses on favorable terms.  

              Mastitis.  The Company exclusively licensed from Alfa Laval
         Agri AB certain base technology used in the mastitis program.
         This technology includes patents and patent applications on
         fibronectin binding proteins from S. Aureus, E. coli. and S.
         agalactia.  The Alfa Laval license calls for payment of an initial
         license fee, royalties, and additional license fees as additional
         patents issue and when the Company commercializes the vaccines.
         As part of the joint development agreement with Virbac, the
         Company arranged for Alfa Laval to grant a direct license to
         Virbac in certain territories.
              
              Other Biopharm Patents.  The Company also holds U.S. patents
         on its FeLV vaccine and drug delivery compounds and a protein
         purification process, and has patent applications pending on
         methods of expressing and purifying proteins made in a baculovirus
         expression system.


         Diagnostic Patents and Licenses

              Harvard University License Agreement.  In 1983, the Company
         and Harvard University entered into an exclusive license agreement
         governing certain inventions relating to HTLV-I made by Dr. Myron
         Essex and others.  In 1987, the license agreement was expanded to
         include additional technology.  The license agreement includes
         Harvard's patents on gp120 and gp160, the envelopes and the
         envelope precursor protein of HIV-1, and gp61, the envelope
         protein of HTLV-I, and patent applications covering various other
         HIV-1, HTLV-I, and simian immunodeficiency virus proteins.  The
         agreement is exclusive, subject to maintenance by the Company of
         satisfactory progress towards commercialization of the licensed
         technology and payment of minimum royalties and grants the Company
         the right to sublicense the patent.  The Company pays royalties
         based upon net sales, subject to reduction in the event the
         Company is required to pay other royalties on the same product to
         third parties.  The Company has granted sublicenses to several
         companies in exchange for license fees and royalty payments and
         expects to grant additional sublicenses.  The license term is
         equal to the term of the relevant patents which expire beginning
         in 2005.  The Company considers the Harvard license to be
         important to its business both for the right to practice the
         subject technology and for the opportunity to obtain royalties,
         sublicense fees, and access to other technology in exchange for
         sublicenses of the Harvard technology.  During 1995, the Company
         elected not to continue prosecution of a patent application
         related to technology for the detection of antibodies to HTLV-II,
         which it had licensed from Harvard in 1993.

              Pasteur Licenses.  The Company and Pasteur in 1989 entered
         into a series of license agreements pursuant to which the Company
         has licensed Pasteur to make diagnostic products under patents and
         patent applications covering the gp120 and p27 proteins of HIV-1
         and the gp61 protein of HTLV-I, and Pasteur has licensed the
         Company to make diagnostic products for HIV-2 and for HIV-1 under
         patent applications covering the gp110 and p27 proteins.  The
         parties must pay each other royalties on sales of certain products
         covered by the agreements. 

              In March 1995, Institut Pasteur, which has an ownership
         interest in Pasteur, and Genetic Systems Corporation, which is a
         wholly-owned subsidiary of Pasteur, brought a patent infringement
         action against the Company with respect to two HIV-2 patents
         licensed to the Company under the license agreements, and a third
         patent related to HIV-1 which was not licensed under the license
         agreements.   CBC filed an answer and counterclaim denying the
         allegations and seeking a declaration of CBC's license rights to
         the two patents under the license agreements.  On September 1,
         1995, the Bankruptcy Court issued summary judgment upholding CBC's
         license under the license agreements to two HIV-2 patents to
         commercialize diagnostic tests for the HIV-2 strain of the AIDS
         virus.  

              With respect to the HIV-1 related patent, the Court ruled
         that CBC's HIV-1 Western Blot confirmatory test for HIV-1
         infringed the patent and enjoined CBC from the manufacture and
         sale of the HIV-1 Western Blot test.  On January 5, 1996, the
         Bankruptcy Court ruled that CBC is only obligated to pay damages
         for infringement on the HIV-1 patent in an amount equal to 1% of
         net sales of HIV-1 Western Blot tests for the period July 7, 1994,
         through December 31, 1995.  The Bankruptcy Court also ruled that,
         beginning on January 1, 1996, CBC has a license for the HIV-1
         patent at a royalty rate of 1% of net sales, based on CBC's rights
         pursuant to a 1987 Settlement Agreement between the United States
         Government and Institut Pasteur.  The Court lifted its injunction
         with respect to the Company's production and sale of the HIV-1
         Western Blot test.  Institut Pasteur has appealed the Bankruptcy
         Court's adverse rulings, and the Company has appealed the Court's
         initial determination that it infringed the HIV-1 patent.  See
         Legal Proceedings.

              Other Diagnostic License Agreements.  The Company is a
         licensee of technology used in various of its diagnostic products.
         These agreements typically provide that the Company pay a license
         fee upon execution and pay royalties based upon net sales, subject
         to minimums in certain cases.  These licenses are typically
         exclusive and may become nonexclusive under certain conditions
         based on the extent of commercialization by the Company of the
         applicable inventions.


                                     COMPETITION

              The biotechnology and pharmaceutical industries are subject
         to rapid and significant technological change.  Competitors of the
         Company in the United States and abroad will be numerous.  They
         include, among others, major pharmaceutical and chemical
         companies, specialized biotechnology firms, universities and other
         research institutions.  There can be no assurance that the
         Company's competitors will not succeed in developing technologies
         and products that are more effective than any which have been
         developed by the Company or may be developed by the Company in the
         future or which would render the Company's technology and products
         obsolete and noncompetitive.  Many of these competitors have
         substantially greater financial and technical resources and
         production and marketing capabilities than the Company.  In
         addition, some of the Company's competitors have substantially
         greater experience than the Company in preclinical testing and
         human clinical trials of pharmaceutical products and in obtaining
         FDA and other regulatory approvals of products for use in
         healthcare.  Accordingly, the Company's competitors may succeed in
         obtaining FDA approval for products more rapidly than could the
         Company.  There can be no assurance that the Company's products
         under development will be able to compete successfully with
         existing products or products under development by other
         companies, universities and other institutions or that they will
         attain regulatory approval in the United States or elsewhere.  If
         the Company commences significant commercial sales of its
         products, it will also be competing with respect to manufacturing
         efficiency and marketing capabilities, areas in which it may have
         less experience.  A significant amount of research in the field is
         also being carried out at academic and government institutions.
         These institutions are becoming increasingly aware of the
         commercial value of their findings and are becoming more
         aggressive in pursuing patent protection and negotiating licensing
         arrangements to collect royalties for use of technology that they
         have developed.  These institutions may also market competitive
         commercial products on their own or in collaboration with
         competitors and will compete with the Company in recruiting highly
         qualified scientific personnel.  

              The Company is aware of certain programs and products under
         development by others which may compete with its programs and
         products.  Several companies, including Ribi Immunochem ("Ribi")
         and Chiron Corporation, are developing adjuvants. 

              At least two of the Company's adjuvant licensees are also
         licensees of Ribi for certain diseases.  Fort Dodge and one other
         company already have canine Lyme disease vaccines on the market,
         while Pasteur Merieux and SmithKline are in advanced human trials
         with a human Lyme disease vaccine.  Merck, Wyeth-Lederle and
         possibly others are in human clinical trials with conjugate
         pneumococcal vaccines for the pediatric market, although not for
         the elderly market.  Several companies market mastitis vaccines
         for infections caused by E. coli, but these vaccines do not
         protect against staphylococcal or streptococcal infections. Merck
         has received regulatory approval for a treatment for osteoporosis.
         At least six companies, including Abbott Laboratories, compete
         with the Company in marketing HIV-1 screening tests, and two other
         companies, Epitope, Inc., and Bio-Rad Laboratories, Inc., have
         obtained FDA approval to market HIV-1 Western blot confirmatory
         tests.  The existence of products developed by these and other
         competitors, or other products of which the Company is not aware
         or which may be developed in the future, may adversely affect the
         marketability of products developed by the Company.


                                GOVERNMENT REGULATION

              The FDA, the USDA, the Environmental Protection Agency and
         the Nuclear Regulatory Commission, comparable state agencies and
         other agencies, including those in foreign countries, impose
         requirements governing the development, manufacture and marketing
         of certain of the Company's products and products under
         development.  The regulatory process can take several years,
         involves lengthy and detailed laboratory and clinical testing, and
         requires substantial expenditures.  Human biologicals and
         pharmaceuticals, including vaccines, typically require three
         stages of clinical trials: Phase I to determine the initial safety
         of the product; Phase II, during which the efficacy of the product
         is preliminarily assessed and treatment regimens refined; and Phase
         III (sometimes referred to as "pivotal trials") during which final
         safety and efficacy data are generated.  Regulatory approval is
         required prior to commencement of initial clinical trials.  The
         clinical data, together with comprehensive manufacturing and
         facility information, is filed with the FDA in a New Drug
         Application (NDA) or Product License Application (PLA), and an
         Establishment License Application (ELA), on which the regulatory
         agencies base their approval decisions.  In some instances,
         particularly in cases of life-threatening diseases for which there
         is no effective treatment, the clinical trial phases may be
         combined, or approval may be sought after completion of an
         expanded Phase II trial.

              QS-21 is currently classified by the FDA as a constituent
         material used in drug preparation.  As a result, the FDA does not
         require licensure of facilities used in its manufacture.  The
         Company believes that this allows it the flexibility to postpone
         investment in commercial manufacturing facilities until after the
         safety and effectiveness of QS-21 has been demonstrated in Phase
         III clinical trials.  The Company has filed with the FDA a
         Biologics Master File for QS-21, which its licensees can reference
         as part of their own PLAs and NDAs as they seek FDA approval.

              There can be no assurance that, at the end of the regulatory
         process, approval will be obtained or that product developments by
         competitors in the interim will not have made the Company's
         products obsolete or economically unfeasible.  The extent of
         regulation which may arise from future legislative or
         administrative action cannot be predicted, nor can the potential
         impact of such future regulation, or changes in existing
         regulation, be predicted with any certainty.


                                  PRODUCT LIABILITY

              The Company has potential liability risks that are inherent
         in the testing, manufacturing and marketing of medical products
         and diagnostic products.  The Company's manufacture and sale of
         diagnostic products may expose it to product liability claims.
         The Company has product liability insurance for its diagnostic
         products at levels which it believes are customary in the
         industry.  The use of the Company's biopharm products in clinical
         trials may expose it to product liability claims and possible
         adverse publicity.  These risks also exist with respect to the
         Company's biopharm products, if any, that receive regulatory
         approval for commercial sale.  The Company currently has limited
         product liability coverage for the clinical research use of its
         products, which management believes is customary for companies
         with products at this stage of clinical development.  The Company
         intends to obtain product liability insurance for other biopharm
         products when commercialized.  Product liability coverage is
         becoming increasingly expensive and there can be no assurance that
         the Company will be able to maintain its existing insurance
         coverage or obtain additional insurance coverage at acceptable
         costs, if at all, or that a product liability claim would not
         materially adversely affect the business or financial condition.

              If and when the Company manufactures vaccines that are
         recommended for routine administration to children, it is possible
         that it will be required to participate in the National Vaccine
         Injury Compensation Program.  This program compensates children
         having adverse reactions to certain routine childhood
         immunizations with funds collected through an excise tax from the
         manufacturers of these vaccines.


                                   HUMAN RESOURCES

              As of March 1, 1996, the Company employed 182 full time
         employees.  The employees are not represented by any labor unions,
         and the Company considers its relations with those employees to be
         good.  The Company's scientific staff has expertise in many
         relevant areas and these internal resources are augmented by
         consulting agreements with research scientists located at various
         academic institutions and commercial organizations.


                              SCIENTIFIC ADVISORY BOARD

              The Company's Scientific Advisory Board consists of six
         individuals with recognized expertise in vaccines.  The Scientific
         Advisory Board meets from time to time to discuss matters relating
         to the Company's current and long-term scientific planning and
         research and development, and the individual members are available
         for consultation on an informal basis. All members of the
         Scientific Advisory Board are employed by academic institutions,
         and may have commitments or consulting or advisory obligations to
         other entities that may limit their availability to the Company.
         These entities may be competitors of the Company.  In certain
         circumstances, the academic institutions which employ the
         Scientific Advisory Board members may assert ownership rights to
         inventions or other technology that may result from advice
         provided to the Company by such members.  In such circumstances,
         the Company could seek to negotiate licenses to such inventions or
         technology, but there can be no assurance that the Company would
         be able to obtain such licenses on commercially reasonable terms.
         No members of the Scientific Board are expected to devote more
         than a small portion of their time to the Company.

              The following persons are the current members of the
         Scientific Advisory Board:

         Item 2.  Properties

              The Company maintains most of its Worcester operations in a
         76,475 square foot leased facility at the Biotechnology Research
         Park in Worcester, Massachusetts.  The facility contains research
         and development laboratories, quality control laboratories,
         manufacturing space and administrative offices.  The building is
         leased pursuant to a lease with a ten year initial term expiring
         December 1996.  The lease provides for an option to extend the
         term for two additional five year periods and an option to cause
         the landlord to build up to an additional 40,000 square feet.
         Since the space exceeds the Company's expected needs for the
         business after the reorganization of the Company, the Company may
         relocate to new space at the end of 1996.  The Company believes
         that suitable replacement space is readily available at reasonable
         rates.  The Company also leases 15,000 sq. ft. of warehouse space
         in Shrewsbury Massachusetts, pursuant to a lease for a five year
         initial term commencing September 1, 1988, which expires in 1996.  
         
              The Company owns three buildings in Rockville, Maryland; its
         main manufacturing building containing approximately 46,000 square
         feet at 1500 East Gude Drive of which approximately 37,015 square
         feet is used for manufacturing; and two laboratory buildings at 3
         Taft Court containing approximately 20,852 square feet and
         approximately 3,800 square feet. The Company leases the 20,852
         square foot laboratory building to Biotech Research Labs, a
         subsidiary of Boston Biomedica Inc., under a five year lease which
         commenced July 1992.


         Item 3.  Legal Proceedings

              On January 3, 1990, the Company instituted suit in the United
         States District Court, District of Connecticut, against
         MicroGeneSys, Inc., and three individual defendants alleging that
         defendants were infringing United States Patent No. 4,725,669, to
         which the Company holds an exclusive license.  The Company sought
         an injunction requiring that MicroGeneSys cease infringing the
         patent by making diagnostic and research products, and requiring
         MicroGeneSys to take a license to make vaccines and drugs.  The
         defendants counterclaimed asserting inter alia that the '669
         patent was not infringed, being either invalid and/or not
         enforceable and that the Company was interfering with business
         advantage and committing unfair trade practices. The Company and
         the defendants have entered into a settlement agreement in which
         the defendants acknowledge that the manufacture, use, or sale of
         certain of MicroGeneSys's current products infringe the '669
         patent.  Simultaneously with the execution of the settlement
         agreement, the Company and MicroGeneSys entered into a license
         agreement giving MicroGeneSys a non-exclusive, worldwide license
         under the '669 patent in certain fields, for which the Company
         will receive a license fee and royalties on the sale of licensed
         products.  The settlement agreement is subject to approval by the
         District Court and the Bankruptcy Court.

              In November 1993, five civil actions were commenced in the
         U.S. District Court, District of Massachusetts, against CBC,
         certain of its officers ("Individual Defendants"), and in three
         cases, against the Company's former auditor.  The claim against
         the auditors was dismissed without prejudice.  The actions were
         instituted by persons alleging to be shareholders of CBC and to be
         representative of a class of shareholders claiming damages
         resulting from alleged violations of securities laws by the
         Company and Individual Defendants in connection with the 1992
         results of CBC and the restatement thereof.  The five actions,
         along with a sixth action filed in the U.S. District Court,
         Southern District of New York in June 1994, were consolidated
         under the caption In Re: Cambridge Biotech Corporation Securities
         Litigation, Civil Action No. 93-12486-REK.  The class comprises
         purchasers of the Company's common stock during the period
         February 28, 1992, through and including May 9, 1994.  The Company
         has successfully negotiated (i) a settlement agreement among the
         class, National Union (the issuer of the Company's directors and
         officers indemnity policy), the Individual Defendants, and the
         directors and officers of the Company, and (ii) a second
         settlement agreement among the class, the Individual Defendants
         substantially all of the Company's directors and officers, and the
         Company.  Generally, pursuant to these settlements, the class will
         receive approximately 25% of the shares to be issued in the
         reorganized Company upon its emergence from Chapter 11, 90% of any
         net recoveries by the class against the Company's former auditors
         (with the Company to receive the other 10% thereof), and
         $1,050,000 previously paid into escrow by National Union. These
         agreements preliminarily have been approved by the United States
         District Court and will be incorporated into the Company's plan of
         reorganization.  The settlement is subject to the confirmation of
         a plan of reorganization by the U.S. Bankruptcy Court.

              On March 19, 1996, the Company filed an action against
         Deloitte & Touche, its former auditors (Cambridge Biotech Corp. v.
         Deloitte & Touche, Superior Court, Suffolk County, Commonwealth of
         Massachusetts, C.A. No. 96-1480-A 1996).  The complaint arises out
         of the defendant's audits of the Company's financial statements
         for 1991 and 1992, and alleges that the defendant acted
         negligently and in breach of contract in performing those audits.
         As a result of defendant's failure to adequately conduct the audit
         in accordance with GAAS and using GAAP, the complaint alleges that
         the financial statements for 1991 and 1992 contained material
         misstatements including overstatements of revenue, income, and
         earnings per share.  The Company is seeking compensation for the
         full amount of its damages, pre-judgment interest, cost, and other
         relief deemed appropriate by the Court.  The Company is not liable
         for the costs and expenses of the litigation.  Any such costs and
         expenses would be paid from any recoveries from the defendant.
         Under its settlement agreement in the shareholder class action
         litigation, the shareholder class will receive 90% and the Company
         will receive 10% of any net recoveries from the defendant.

              On July 7, 1994, the Company filed for protection under
         Chapter 11 of the United States Bankruptcy Code and is a debtor in
         possession pursuant to a voluntary petition filed in the United
         States Bankruptcy Court for the District of Massachusetts, Western
         Division, Case Number 94-43054-JFQ.

              In July of 1994, the Securities and Exchange Commission
         issued an Order Directing Private Investigation (In the matter of
         Cambridge Biotech Corporation, United States of America Before the
         Securities and Exchange Commission, File no. B-1238),
         investigating matters pertaining to CBC's financial statements,
         its public filings, and its offerings of its securities.  CBC is
         cooperating fully with the investigation, which is ongoing.  The
         Department of Justice is conducting its own independent
         investigation, which the Company believes is focusing on matters
         similar to the investigation of the SEC.  CBC is cooperating in
         the investigation and has been informed informally by the U.S.
         Attorney's Office that no present officer or director is a target
         of the investigation.

              In March 1995, Institut Pasteur and Genetic Systems
         Corporation brought a patent infringement action against the
         Company with respect to two HIV-2 related patents licensed to the
         Company, and a third patent related to HIV-1.  CBC filed an answer
         and counterclaim denying the plaintiff's allegations and seeking a
         declaration of CBC's license rights to the two HIV-2 patents.  On
         September 1, 1995, the Bankruptcy Court issued summary judgment
         upholding CBC's license under two license agreements with Pasteur
         to the HIV-2 patents.  The Court also ruled that CBC's HIV-1
         Western Blot confirmatory test for HIV-1 infringed the patent and
         enjoined CBC from the manufacture and sale of the HIV-1 Western
         Blot test. On January 5, 1996, the Bankruptcy Court ruled that CBC
         is only obligated to pay damages for infringement on the HIV-1
         patent in an amount equal to 1% of net sales of HIV-1 Western Blot
         tests for the period July 7, 1994 through December 31, 1995.  The
         Bankruptcy Court also ruled that, beginning on January 1, 1996,
         CBC has a license for the HIV-1 patent at a royalty rate of 1% of
         net sales, based on CBC's rights pursuant to a 1987 Settlement
         Agreement between the United States Government and Institut
         Pasteur, and lifted its injunction with respect to the Company's
         production and sale of the HIV-1 Western Blot test. Institut
         Pasteur has appealed the Bankruptcy Court's adverse rulings, and
         the Company has appealed the Court's initial determination that it
         infringed the HIV-1 patent. 

              On September 18, 1995, the Company filed a declaratory action
         against Institut Pasteur (In re Cambridge Biotech Corporation v.
         Institut Pasteur in the United States Bankruptcy Court for the
         District of Massachusetts, Western Division, Adversary Proceeding
         Number 95-04278), asking the Court to determine its right to
         obtain a license to Institut Pasteur's patent covering HIV-1.  The
         action was dismissed as moot upon the Court's determination in the
         patent infringement litigation filed by Institut Pasteur and
         Genetic Systems that beginning on January 1, 1996, CBC has a
         license for the HIV-1 patent based on CBC's rights pursuant to a
         1987 Settlement Agreement between the United States Government and
         Institut Pasteur.

              In May 1995, a former employee of the Company filed a
         complaint against the Company with the City of Rockville, Maryland
         Human Rights Commission, claiming wrongful termination (Human
         Rights Commission on the Complaint of Paul R. Shackleford against
         Cambridge Biotech Corporation, Complaint No. 95-15-ER).  The
         Company disputes the allegations and will defend the complaint,
         which has been stayed as a result of the bankruptcy proceeding.

              On January 2, 1996, CBC received from the United States
         Environmental Protection Agency ("EPA") a Notice of Potential
         Responsibility and Request for Information under the Comprehensive
         Environmental Response, Compensation and Liability Act ("CERCLA")
         relating to the EPA's investigation of the RAMP Industries, Inc.
         site ("RAMP Site") in Denver, Colorado.  The letter serves as
         notice to CBC of its potential liability under Section 107(a) of
         CERCLA, with respect to the RAMP Site.  CBC responded by letter to
         the EPA dated February 1, 1996 stating that it did not believe it
         was a potentially responsible party and that it believed that all
         Company waste shipped to the Site had been removed from the Site
         prior to EPA incurring any CERCLA costs.  While the Company
         intends to fully cooperate with the investigation which is
         ongoing, it also intends to defend any claim that may be asserted
         by EPA.


         Item 4.  Submission of Matters to a Vote of Security Holders.

              No matters were submitted to security holders during the
         quarter ended December 31, 
         1995.

The above prices may not necessarily represent actual transactions.  The

on the NASD National Market System.  Effective June 9, 1994 the Company's
stock was delisted and therefore, the prices for subsequent quarters are
the last sales prices for transactions reported by brokers on the over the
counter market.

As of March 15, 1996, there were approximately 3,137 shareholders of record
of the Company's common stock.

Item 7. MANAGEMENT'S DISCUSSSION AND ANALYSIS OF FINANCIAL CONDITION AND 
        RESULTS OF OPERATIONS.

General
- -------
The Company filed for protection under Chapter 11 of the United States 
Bankruptcy Code ("Chapter 11") on July 7, 1994 and is managing its assets
and operating its businesses as a debtor in possession pursuant to a 
voluntary petition filed in the United States Bankruptcy Court for the
District of Massachusetts, Western Division (the "Bankruptcy Court"),
Case Number 94-43054-JFQ.  Since the Chapter 11 filing, management has
spent considerable time reviewing the Company's strategic direction, as
well as specific products and programs.  It has sold or disposed of certain
assets and operations of the Company, as described below, which did not
fit within the business plan for reorganizing the Company.  The Company
is also considering a possible sale of the Company's diagnostics division 
or portions thereof.  Any potential sale must be approved by the Bankruptcy
Court.

On March 30, 1994, the Company's former independent accountants, who
resigned from their engagement to audit the Company's 1993 financial 
statements, withdrew their opinion on the Company's 1992 financial 
statements, and raised concerns over certain transactions that had come 
to their attention.  The Company's board of directors appointed a special 
committee of two outside directors which was assisted by special
counsel to conduct an investigation into the matters raised by the former
accountants.  The investigation confirmed the existence of several trans-
actions which did not appear to be bona fide or which were incorrectly 
recognizing revenue.  On May 9, 1994, the Company announced that it had
replaced its Chief Executive Officer and that two of its other officers had 
resigned.  In April 1995, the Company elected Alison Taunton-Rigby, Ph.D. 
as its new President and Chief Executive Officer.

The Securities and Exchange Commission ("SEC") on July 22, 1994 issued an
Order Directing Private Investigation pertaining to the Company's financial
statements, its public filings and the offerings of its securities.  On
September 21, 1995, the Company received a subpoena issued by the United
States District Court, District of Massachusetts for documents to be 
presented to the Grand Jury.  The Company believes the United States Attorney
is conducting an investigation similar to that of the SEC.  The Company is
cooperating fully with both of the investigations.

Effective June 9, 1994, the Company's stock was de-listed by the National
Association of Securities Dealers (NASD) due to the Company's failure to 
comply with NASD's listing requirements as a result of its inability to
provide audited financial statements.

Results of Operations
- ---------------------
Management has concluded that because of the events described above and in 
light of the Company's financial condition and Chapter 11 filing, it would 
not be feasible for its new accountants to perform an initial audit of the 
Company's 1993 financial statements.  Consequently, the accompanying 
financial statements and footnotes do not show comparative data for 1993.
                                 
Revenues:
- --------
Total revenues were $27,868,000 and $22,100,000 in 1995 and 1994, 
respectively.  Product sales were $20,854,000 and $16,683,000 in 1995
and 1994, respectively.  The increase in product sales was due primarily to 
sales attributable to the operations of the Company's consolidated 
subsidiary, Cambridge Affiliated Corporation ("CAC"), of which the Company 
owns 51%.  CAC, which was established in December of 1994, had product sales 
of $2,788,000 and $231,000 in 1995 and 1994, respectively.  Product sales
of the Diagnostics division represented $17,475,000 (84%) in 1995 and 
$16,007,000 (96%) in 1994 of the product sales.  Ortho Diagnostics Systems, 
Inc. (Ortho) is the Company's principal distributor for diagnostics 
products.  All of the Company's products marketed by Ortho are under a joint 
Cambridge Biotech/Ortho label.  Sales to Ortho represented 30% and 32% of the 
Company's total revenue in 1995 and 1994, respectively.

Research and Development ("R&D") revenues were $5,137,000 and $4,334,000
in 1995 and 1994, respectively.  R&D revenue relates principally to the 
biopharmaceutical division.  The majority of these revenues were generated
from license agreements.  In 1995 and 1994 the Company recognized $3,500,000 
and $3,000,000, respectively, in license fees under an agreement with 
SmithKline Beecham p.l.c. ("SKB") which allows SKB to use the Company's 
proprietary Stimulon TM adjuvant ("QS-21") in numerous vaccines, including
hepatitis, lyme disease, human immunodeficiency virus (HIV), influenza
and melanoma.  Income from this agreement represented 13% and 14% of the 
Company's total revenue in 1995 and 1994, respectively.  The Company also 
recognized revenue from its collaboration with Virbac S.A. on the research 
and development of vaccines for feline immune deficiency virus (FIV) and 
bovine mastitis.  In 1995 and 1994 the revenue recognized on these two 
projects totaled $1,053,000.  Additional deferred revenue totaling $2,072,000 
will be recognized as research expense is incurred for these projects.

Royalty revenue in 1995 and 1994 was 7% ($1,877,000) and 5% ($1,082,000) of 
the Company's total revenue, respectively.  These royalties were received
as a result of licenses granted to use the Company's proprietary technology, 
know-how and patents.  The increase is primarily attributable to a partner
exercising an option to obtain a license for one of the Company's products.

Costs and Expenses:

Cost of sales as a percentage of product sales was 77% and 87% in 1995 and
1994, respectively.  The diagnostics division, which accounts for the 
majority of product sales, had more favorable cost of sales margins in 1995 
compared to 1994.  CAC, which has a cost of sales of 76% in 1995 and 1994, 
accounted for 13% and 1% of cost of sales in 1995 and 1994, respectively.  
Product mix changes are the primary reasons for the more favorable cost of 
sales margin in 1995.  

Research and development expenses represented 23% ($6,454,000) and 27% 
($5,860,000) of total revenue in 1995 and 1994, respectively.  
Biopharmaceutical research accounted for 91% ($5,844,000) and 87% 
($5,100,000) of the total R&D expense in 1995 and 1994, respectively.
The increase is primarily attributable to a milestone obligation for an 
additional patent allowed on technology licensed by the Company.

Sales, general and administrative expenses ("S,G&A") were $9,955,000 and 
$10,274,000 in 1995 and 1994, respectively.  Such expenses represented 36% 
and 46% of total revenue of 1995 and 1994, respectively.  The reduction in 
S,G&A relates principally to a reduction in personnel. 

As a result of the Company filing for reorganization under Chapter 11, the
Company re-evaluated its long-lived assets based upon undiscounted future
cash flows and stated them at net realizable value in accordance with 
Financial Accounting Standard No. 121 "Accounting for the Impairment of 
Long-Lived Assets and for Long-Lived Assets to Be Disposed Of."  
Accordingly, during 1994 the Company recognized a loss on impairment of 
long-lived assets in the amount of $2,879,000, representing $1,734,000 of
purchased technology and $1,145,000 on its property and plant in Rockville,
Maryland.

Other Income and Interest Expense:

The Company recognized net other income of $581,000 in 1995 compared to net
other expenses of $473,000 in 1994.  Included in other income is $170,000 of 
interest income earned prior to the Company filing for Chapter 11 protection 
in 1994.   The Company considered all interest income ($387,000) earned in 
1995 on cash accumulated as a result of Chapter 11.  In 1995 and 1994 the 
Company recognized $13,000 and $302,000 of interest expense on its debt.  
The accrual of interest expense on principally all debt incurred prior to 
Chapter 11 was suspended since the Company's Chapter 11 proceedings.  In 1994 
the Company sold its interest in ImmuCell Corporation and recognized a loss 
of $306,000.  In 1995 the Company recognized income of $183,000 upon receipt 
of stock resulting for the Company's ownership position in one of its 
employee benefits providers.

Reorganization items:

The Company incurred expenses of $1,200,000 and $611,000 in 1995 and 1994,
respectively, for professional fees in relation to its filing for reorgan-
ization under Chapter 11.  The Company also accrued a provision in 1994 for
rejected executory contracts totaling $358,000.  Interest earned on 
accumulated cash resulting from Chapter 11 proceedings was $387,000 and
$100,000 in 1995 and 1994, respectively.

Income taxes:

The Company recorded an income tax benefit of $207,000 in 1994 due to the
reversal of prior year tax accruals.

Discontinued Operations:

On July 21, 1994 the Company's wholly-owned subsidiary, Cambridge Biotech
Ltd. (CBL), filed for protection of the Irish High Court and an examiner
was appointed pursuant to the Irish Companies Act of 1990.  As of that date,
the Company recorded a loss related to the discontinued operations.  CBL's
1994 product sales of $1,952,000 were included in the process of calculating 
the $2,129,000 loss from discontinued operations.  Under the reorganization 
plan for CBL, on November 30, 1994, the Company's interest as an equity 
holder and its claim as a creditor were transferred to SelfCare Inc. 
and the Company received $2,083,000 in cash for the transfer of certain 
technology pertaining to products manufactured at the Irish facility.  The 
Company recorded a loss in 1994 of $6,963,000 on the sale of the discontinued 
operations.  Effective with the disposal of CBL, the Company also wrote off 
registration rights and distribution contracts which were recorded by the 
Company's subsidiary, Cambridge Biotech International Corporation (CBIC).  
The loss on disposal of these assets was $519,000.  Additionally the Company 
included a discontinued operations loss for CBIC of $133,000.  The combined 
loss from discontinued operations and disposal on these two operations in 
1994 was $2,262,000 and $7,482,000, respectively.

Net Income (Loss):

The Company had a loss of $4,942,000 or $0.19 per share and $12,533,000 or 
$0.48 per share in 1995 and 1994, respectively, from continuing operations.  
In 1994, the Company had a net loss of $22,276,000 or $0.86 per share 
including the loss from discontinued operations.

Liquidity and Capital Resources

The Company's ability to fund its long term operations is dependent on 
several factors, including the sale of the Company's diagnostics business,
the formulation and confirmation of a viable plan of reorganization and
the Company's ability to attract additional funding through public or 
private financing or collaborative arrangements.  There can be no assurance 
that adequate operating funds will be generated through the sale of the 
diagnostics business or that additional funding can be obtained on acceptable 
terms.  

Operating activities used $880,000 and $3,095,000 of cash in 1995 and 1994, 
respectively.  The 1995 net loss of $4,942,000 included non-cash depreciation
and amortization of $4,737,000.  The 1994 net loss of $22,276,000 included 
various non-cash items including the loss on discontinued operations 
($7,482,000), depreciation and amortization ($4,282,000) and loss from asset 
impairment ($2,880,000).  In 1994 the Company reduced accounts receivable by 
$975,000 and inventory levels by $1,524,000.  The $3,500,000 SKB license 
payment received in 1994 was earned in 1995 which was the primary reason for 
the reduction in deferred revenue.  

Accounts payable and other liabilities increased by $3,349,000 and $2,258,000 
in 1995 and 1994, respectively.  The 1995 increase was due primarily to the 
patent related milestone obligation previously mentioned, employee retention 
bonus plan and timing of payments.  The 1994 increase was primarily due to
postponed payments due to a cash shortage prior to filing Chapter 11, 
employee retention bonus plan and professional fees incurred due to the 
Company's filing for Chapter 11.  

The Company's 1995 investing activities used cash of $798,000.  The Company's
1994 investing activities provided cash of $5,262,000.  During 1994 the 
Company sold marketable securities totaling $4,140,000, of which $1,026,000 
was pledged as collateral under a sale/leaseback arrangement with Fleet 
Credit Corporation for equipment.  In 1995 the Company limited capital 
expenditures due to its financial position.  In 1994 the Company invested 
$2,118,000 in property, plant, and equipment, $1,026,000 of which was used 
to repurchase the equipment under the above mentioned sale/leaseback.  
In 1994 the Company sold its interest in CBL's debt and equity to SelfCare, 
Inc. for $2,082,000 and its interest in ImmuCell Corporation for $309,000.

The Company's 1994 financing activities provided $5,455,000 principally as a 
result of raising $6,635,000 in the sale of its stock in the first quarter of 
1994 and repaying $1,377,000 on long-term obligations.  In the future, the 
Company will seek additional funding through additional public or private 
financing, and collaborative arrangements and dispositions of portions of 
the business.  The Company presently is seeking to sell the diagnostics 
division or portions thereof as a source of funds.   

At December 31, 1995 and 1994, the Company had cash and cash equivalents
totaling $6,856,000 and $8,538,000, respectively.  At December 31, 1995, the
Company had total working capital of $7,977,000 and a current ratio of 2.15
to 1 compared to total working capital of $8,886,000 and a current ratio of
2.20 to 1 at December 31, 1994.  However, the Company had approximately 
$9,880,000 and $9,715,000 at December 31, 1995 and 1994, respectively in 
liabilities subject to Chapter 11 proceedings, and if all of these liabilities
were considered current liabilities, the current ratio would have been 0.89
and 0.95 to 1, respectively.

In a Chapter 11 case, substantially all liabilities as of the date of filing 
of the petition for reorganization are subject to settlement under a plan of
reorganization to be voted upon by the creditors and equity security holders
and approved by the Bankruptcy Court.  The Company continues to manage its
affairs and operate its business as a debtor in possession, subject to the
supervision of the Bankruptcy Court while the case is pending.  In the event
a plan of reorganization is approved by the Bankruptcy Court, continuation
of the business after reorganization is dependent upon the success of future
operations and the Company's ability to meet obligations as they become
due.  The accompanying financial statements have been prepared on a going
concern basis, which contemplates continuity of operations, realization
of assets and liquidation of liabilities in the ordinary course of business.
As a result of the reorganization proceedings, the Company may have to sell
or otherwise dispose of assets and liquidate or settle liabilities for
amounts other than those reflected in the financial statements.  The 
financial statements do not give effect to adjustments to the carrying value
of assets, or amounts and reclassification of liabilities that might be 
necessary as a consequence of these bankruptcy proceedings.  The
appropriateness of using going concern basis accounting is dependent upon, 
among other things, confirmation of a plan of reorganization, success of 
future operations, and the ability of the Company to generate sufficient 
cash from operations and financing sources to meet its obligations.  There
can be no assurances that these events will occur.

                                Fiscal Year End Option/SAR Value Table

              The following chart shows the number and value of unexercised 
        options held by each of the Named Executive Officers at the end of the 
        Company's last fiscal year.  The value shown for each option is equal 
        to the difference between the exercise price of the option and the fair 
        market value of the underlying stock at fiscal year end.  The Company 
        has never awarded any stock appreciation rights to any of its 
        employees, and thus none are outstanding.  None of the Named Executive
        Officers exercised any options during the Company's last fiscal year.

        Board Compensation Committee Report on Executive Compensation

              During 1995, the Company continued to operate as a 
        Debtor-in-Possession under the protection of Chapter 11 of the United 
        States Bankruptcy Code.  Thus the Company's compensation committee 
        (the "Committee") was not working in a normal operating environment and
        in many respects was unable to play its traditional role of 
        establishing  consistent long-term performance-based compensation 
        goals.

              Traditionally, the Company's compensation for its executive 
        officers, including its chief executive officer, has consisted of 
        three key elements: base salary, discretionary annual bonus, and
        periodic grants of stock options or other long-term compensation. The 
        Committee has historically made judgements as to the components of 
        compensation based upon its review of the Company's results and each 
        individual's performance. The Committee's goal has been to provide an 
        appropriate balance between base salary and incentive compensation 
        awarded upon achievement of long-term goals.

              During 1995, the Company had two chief executive officers.  Mr. 
        Beaver, a director (now Chairman of the Board) served as interim chief 
        executive officer beginning in May 1994.  During the early months of 
        1995, the Company conducted a search for a new CEO, which resulted in 
        the election of Dr. Taunton-Rigby as chief executive officer ("CEO") of 
        the Company effective April 6, 1995.  Mr. Beaver submitted his 
        resignation as chief executive officer of the Company effective April
        6, 1996.

              In determining the terms of Dr. Taunton-Rigby's employment 
        contract, including base salary of $225,000, participation in the 
        Management Bonus Plan, stock options, and other benefits, the
        Committee reviewed levels of salary and other benefits available to 
        other CEOs in the industry.  The Committee believed that the Company 
        must offer competitive compensation in order to attract a
        person with substantial experience capable of developing the Company's 
        technology and bringing the Company out of bankruptcy.  In addition 
        the Committee felt it necessary to provide significant incentives to 
        induce the CEO to undertake the task of guiding the Company through 
        its emergence from bankruptcy.  The Committee awarded Dr. 
        Taunton-Rigby a bonus for 1995 of 35% of her salary, one-third in cash 
        and two-thirds in stock of the Company's successor upon emergence of 
        the Company from bankruptcy.

              The Committee also reviewed the salaries of other executive 
        officers, all of whom are under employment contracts.  The salaries of 
        Dr. Kammer, Dr. Beltz and Ms. Grabbe were all adapted to the level 
        indicated in their employment contracts.  The Committee adopted a 
        management bonus program in March of 1995.  The Committee awarded Dr. 
        Kammer, Mr. Beltz and Ms. Grabbe a bonus for 1995 of 20% of their 
        respective salaries, one-third in cash, two-thirds in stock of the 
        reorganized company, prorated to the start date of their employment 
        contracts.

                         REPORT OF INDEPENDENT ACCOUNTANTS


        We have audited the consolidated financial statements and the
        financial statement schedule of Cambridge Biotech Corporation
        (debtor in possession, effective July 7, 1994) listed in Item
        14(a)1. of this Form 10-K.  These consolidated financial
        statements and the financial statement schedule are the
        responsibility of the Company's management.  Our responsibility is
        to express an opinion on these consolidated financial statements
        and the financial statement schedule based on our audits.

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

        In our opinion, the consolidated financial statements referred to
        above present fairly, in all material respects, the financial
        position of Cambridge Biotech Corporation as of December 31, 1995
        and 1994 and the consolidated results of its operations and its
        cash flows for the years then ended, 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,
        present fairly, in all material respects, the information required
        to be included therein.

        The accompanying consolidated financial statements have been
        prepared assuming that the Company will continue as a going
        concern.  As discussed in Notes 1 and 13 to the consolidated financial
        statements, Cambridge Biotech Corporation filed a voluntary
        petition for relief under Chapter 11 of the United States
        Bankruptcy Code on July 7, 1994, civil actions have been filed
        against the Company by certain shareholders, and the Company is
        subject to a Securities and Exchange Commission order directing
        private investigation.  The civil actions against the Company have
        been temporarily stayed as a result of the Company's bankruptcy.
        Although the Company is currently operating its business as a
        debtor in possession under the jurisdiction of the Bankruptcy
        Court, the continuation of the Company's business as a going
        concern is contingent upon, among other things, the ability to
        formulate a plan of reorganization which will gain approval of the
        creditors and confirmation by the Bankruptcy Court, and the final
        settlement of the shareholder litigation and the Securities and
        Exchange Commission order directing private investigation.  These
        matters raise substantial doubt about the Company's ability to
        continue as a going concern.  The consolidated financial
        statements do not include any adjustments that may be required in 
        connection with restructuring the Company as it reorganizes under 
        Chapter 11 of the United States Bankruptcy Code, and the final 
        settlement of the shareholder litigation and the Securities and 
        Exchange Commission order directing private investigation.

         NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

         1.   CHAPTER 11 REORGANIZATION

         Cambridge Biotech Corporation (the "Company" or "CBC") filed a
         petition for reorganization under Chapter 11 of the United States
         Bankruptcy Code ("Chapter 11") on July 7, 1994 with the United
         States Bankruptcy Court for the District of Massachusetts Western
         Division (the "Bankruptcy Court").  In a Chapter 11 case,
         substantially all liabilities as of the date of filing of the
         petition for reorganization are subject to settlement under a plan
         of reorganization to be voted upon by the creditors and equity
         security holders and approved by the Bankruptcy Court.  The
         Company continues to manage its affairs and operate its business
         as a debtor-in-possession, subject to the supervision of the
         Bankruptcy Court while the case is pending.

         In the event a plan of reorganization is approved by the
         Bankruptcy Court, continuation of the business after
         reorganization is dependent upon the success of future operations
         and the Company's ability to meet obligations as they become due.
         The accompanying financial statements have been prepared on a
         going concern basis, which contemplates continuity of operations,
         realization of assets and liquidation of liabilities in the
         ordinary course of business.  As a result of the reorganization
         proceedings, the Company may have to sell or otherwise dispose of
         assets and liquidate or settle liabilities for amounts other than
         those reflected in the financial statements.  The financial
         statements do not give effect to all adjustments to the carrying
         value of assets, or amounts and reclassification of liabilities
         that might be necessary as a consequence of these bankruptcy
         proceedings.  The appropriateness of using the going concern basis
         is dependent upon, among other things, confirmation of a plan of
         reorganization, success of future operations, and the ability of
         the Company to generate sufficient cash from operations and
         financing sources to meet its obligations.  

         2.   SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

         Principles of Consolidation - The financial statements include
         Cambridge Biotech Corporation and its subsidiaries, Biotech
         Research Laboratories, Inc., FSC (FSC), and Cambridge Affiliated
         Corporation (CAC), of which CBC owns 51%.  Cambridge Biotech Ltd.
         (CBL), a subsidiary, was sold during 1994 (see Note 3) and is no
         longer included in the Company's Consolidated Balance Sheet.
         CBL's revenue and expenses from January 1, 1994 to July 21, 1994
         are reflected on the Statement of Operations as a loss from
         discontinued operations.  Cambridge Biotech International
         Corporation ("CBIC") ceased operations in 1994 (see Note 3).  FSC
         is a foreign sales corporation which was dissolved by the Company
         on January 27, 1995.  All significant intercompany transactions
         and accounts have been eliminated.





         Nature of Operations - The Company is in the business of
         developing, manufacturing and marketing products for the
         prevention, detection, and treatment of diseases in humans and
         animals.  Its Diagnostic Division has developed an extensive line
         of diagnostic products for the detection of infectious diseases.
         Its Biopharmaceutical Division has and is developing vaccines and
         other products that stimulate the immune system to control or
         prevent infectious diseases and cancer.  The principal market for
         the Company's products are in the U.S.  The Diagnostic Division is
         responsible for a significant portion of the Company's total
         revenues.

         The Company is subject to risks common to companies in the
         biotechnology industry including, but not limited to, development
         by the Company or its competitors of new technological
         innovations, dependence on key personnel, protection of
         proprietary technology, and compliance with FDA government
         regulations.

         Basis of Presentation - Certain prior year amounts have been
         reclassified to conform with current year presentation.

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

         Cash and Cash Equivalents - The Company considers all highly-
         liquid debt instruments purchased with a maturity of three months
         or less to be cash equivalents.  Cash equivalents include money
         market accounts, certificates of deposit, commercial paper and
         short-term investments.

         Concentrations of Credit Risk - At December 31, 1995, the Company
         has 83% of its cash and cash equivalents invested in commercial
         paper of three financial institutions in the following
         percentages:  55%, 27% and 18%.  The remaining cash and cash
         equivalents are primarily in government-backed securities.  All of
         the above mentioned securities had maturities of less than 45 days
         as of December 31, 1995.

         Marketable Securities - The Company has classified its marketable
         securities as "available for sale".  All marketable securities
         represent shares of common stock of one insurance company and are
         valued at fair value which approximates cost.  There are no
         realized or unrealized gains in 1995.  

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





         Property, Plant and Equipment - Property, plant and equipment are
         recorded at cost.  However, the Company evaluates its property,
         plant and equipment based upon undiscounted cash flows and states
         their net realizable value in accordance with the Financial
         Accounting Standard No. 121 "Accounting for the Impairment of
         Long-Lived Assets and for Long-Lived Assets to Be Disposed Of"
         ("FAS 121"). Depreciation for financial accounting purposes is
         computed substantially by the straight-line method to amortize the
         cost of various classes of assets over their estimated useful
         lives.  The estimated useful lives of the assets are as follows:

                                                      Useful Life
         Buildings                                        30
         Furniture, fixtures and equipment               3 - 10
         Leasehold and building improvements      Lesser of Useful Life 
                                                 for the Term of the Lease

         Maintenance and repairs are charged to operations as incurred,
         whereas additions and improvements are capitalized.  Gains and
         losses on the disposition of properties, if reflected in earnings
         and the related asset costs and accumulated depreciation, are
         removed from the respective accounts.

         Purchased Technology and Patents - Purchased technology related to
         the acquisition of assets is recorded at fair market value at
         acquisition date.  The Company evaluates its purchased technology
         and patents based upon undiscounted cash flows and states their
         net realizable value in accordance with FAS 121.  Capitalized
         patent costs include product registrations and costs incurred for
         the support and protection of existing patents.  Purchased
         technology and patents are amortized on a straight-line basis over
         periods ranging from three to seven years.

         Revenue Recognition - Revenue from product and service sales is
         recognized at the time of the product shipment or performance of
         the service.  Revenue from research and development contracts is
         deferred and recognized over the contractual periods as services
         are performed.  In addition, research agreements which have
         established payments for distinct achievements or phases are
         recorded as income as earned.  The initial fee in alliance
         agreements is recognized when a definitive agreement is reached
         and no contingent factors are present.

         Research and Development Costs - Research and development costs
         are charged to operations as incurred.

         Income Taxes - The Company uses the asset and liability method of
         accounting for income taxes.  Under this method, deferred tax
         assets and liabilities are recognized for the expected future tax
         consequences of temporary differences between the carrying amounts
         and the tax bases of assets and liabilities using the current
         statutory tax rates.





         Net Loss Per Share - The net loss per share is computed based on
         the weighted average number of shares of common stock outstanding
         during each period.  Common equivalent shares are not included in
         the per share calculation because the effect of their inclusion
         would be anti-dilutive.

         3.   DISCONTINUED OPERATIONS

         On July 21, 1994 the Company's wholly-owned Irish subsidiary, CBL,
         filed for protection of the Irish High Court and an Examiner was
         appointed pursuant to the Irish Companies Act of 1990.  At July
         21, 1994 CBL's debt to the Company represented approximately 92%
         of CBL's total liabilities.

         The appointment of the Examiner and the doubtful recovery of the
         Company's investment in CBL have led the Company to conclude the
         measurement date, under the Accounting Principles Board Statement
         No. 30 "Reporting the Results of Operations - Reporting the
         Effects of Disposal of a Segment of a Business, and Extraordinary,
         Unusual and Infrequently Occurring Events and Transactions"  ("APB
         30"), to be July 21, 1994.  Consequently the accompanying
         financial statements for 1994 include a loss of $2,129,000 from
         the discontinued operations for the period January 1, 1994 through
         July 21, 1994.  Net revenues from discontinued operations were
         $1,952,000 for the period prior to disposal.

         On November 30, 1994 the Company sold its interest in CBL's debt
         and equity to SelfCare, Inc. (a U.S. Corporation).  Total
         consideration for the transaction was approximately $2.1 million.
         CBL was classified as a discontinued operation as of the July 21,
         1994 measurement date and a $6,963,000 charge was recorded for the
         loss in 1994.

         The Company, through the acquisition of certain assets of
         Codiapharm, S.A. in November, 1991 obtained product registration
         rights and distribution contracts for the sale of products
         manufactured by CBL, the Company's Irish subsidiary.  These assets
         were  recorded by the Company's subsidiary CBIC.  Effective with
         the disposal of CBL, the Company has written off the value of
         CBIC's assets, and included this loss of $519,000 in the loss on
         disposal in 1994.

         On March 11, 1994 the Company sold its 54% ownership of ADI
         Diagnostics, Inc. to the minority shareholder, Biomira Inc., and
         received net proceeds of $910,000 in 1994.  The Company had
         accounted for ADI as a discontinued operation in 1993, and
         accordingly, consistent with APB 30, the results of ADI and loss
         on disposal are not included in the accompanying financial
         statements.





         4.   INVENTORIES

         Inventories consist of the following at December 31:

                                            1995               1994

                                         =======             =======
         5.   INVESTMENTS

         The Company owns a 19% interest in GRF Corporation (GRF) as part
         of a joint venture formed  to develop and market human growth
         hormone releasing factor (GHRF) thought to be beneficial in the
         treatment of osteoporosis and other diseases.  The remainder of
         this company is beneficially owned by BioNebraska, Inc. and R&C
         Enterprises, Inc.  The Company provided the initial funding of $2
         million.  GRF is conducting a pilot study testing the use of GHRF
         to treat osteoporosis.  Depending on the results of the pilot
         study, the Company has the right to fund additional studies and
         potentially increase its equity interest in the joint venture.
         While growth hormone levels have increased in the majority of
         patients in response to treatment, the data are incomplete.  The
         Company has recorded valuation adjustments of $111,000 and
         $226,000 in the Company's 1995 and 1994 Statement of Operations,
         respectively for its investment in GRF.  Due to the uncertainty
         that the joint venture will be able to raise additional funding to
         support its activities, this investment has been fully written
         off.

         The Company had an investment in ImmuCell Corporation, which was
         accounted for on the cost method.  In December, 1994 the Company
         sold its interest in ImmuCell for $309,000, recognizing a $306,000
         loss in 1994.





         6.   PROPERTY, PLANT, AND EQUIPMENT

         Property, plant, and equipment consists of the following at
         December 31:             
                                                 1995          1994

                                              =========       ========

         Total depreciation expense during 1995 and 1994 was $3,492,000 and
         $3,174,000, respectively.  Accumulated depreciation on property
         leased to others was $603,000 and $588,000 at December 31, 1995
         and 1994, respectively.

         As a result of the Company filing for reorganization under Chapter
         11, the Company evaluated its facilities in Rockville, Maryland
         based upon undiscounted future cash flows and stated them at net
         realizable value in accordance with FAS 121.  Accordingly, the
         Company recognized an impairment loss of $1,145,000 on its
         property and plant in Rockville during 1994.

         undiscounted future cash flows and stated them at net realizable
         value in accordance with FAS 121.  Accordingly, the Company

         consolidation of the Rockville manufacturing facilities and
         processes into the Worcester, Massachusetts and Galway, Ireland
         locations.  The Company made $121,000 and $351,000  in 1995 and
         1994, respectively, in payments against this reserve.  The
         remaining balance of $257,000 at December 31, 1995 consists of
         estimated severance costs and related expenses.

         9.   DEBT

         The Company was in default of its debt agreements as of December
         31, 1995 and 1994, with the exception of the capital lease
         agreement, and the balance is included in liabilities subject to
         Chapter 11 proceedings (Note 10).  The debt consists of the
         following at December 31:





                                                    1995          1994

         The two building loans are collateralized by land, buildings and
         improvements with a carrying value of approximately $3,950,000.
         These loans are in default because of the Company's Chapter 11
         filing; however, payment has been stayed by the Bankruptcy Court,
         pending resolution of the Chapter 11 proceedings.  The prime rate
         was 8.5% at December 31, 1995 and 1994, respectively.

         10.  LIABILITIES SUBJECT TO CHAPTER 11 PROCEEDINGS

         As described in Note 1, since July 7, 1994 the Company has been
         operating as debtor-in-possession under Chapter 11 and is subject
         to the jurisdiction and supervision of the Bankruptcy Court.  In
         Chapter 11 cases, substantially all liabilities of the debtor as
         of the date of the filing of the petition for reorganization will
         be subject to settlement under the plan or plans of
         reorganization.  These amounts may be subject to future
         adjustments depending on Bankruptcy Court actions and further
         developments with respect to disputed claims.  Accordingly, the
         ultimate amount of, and settlement terms for, such liabilities is
         not presently determinable.

         Schedules were filed with the Bankruptcy Court setting forth the
         assets and liabilities of the Company as of the filing date as
         recorded in the Company's accounting records.  Claimants could
         file claims until various bar dates set by the Court.  Differences
         between amounts shown by the Company and claims filed by the
         creditors are currently being investigated.  After completion of
         the reconciliation, any remaining differences may be resolved by
         negotiated agreement between the Company and the claimant or by
         the Bankruptcy Court as part of the Chapter 11 proceedings or
         otherwise.





         Under the Bankruptcy Code, debtors may elect to assume or reject
         real estate leases, employment contracts, personal property
         leases, service contracts and other unexpired executory
         prepetition contracts, subject to Bankruptcy Court approval.

         The principal categories of claims included in Liabilities Subject
         to Chapter 11 Proceedings in the Consolidated Balance Sheet are
         set forth below:

                                                    1995          1994

                                               =========     =========

         These amounts represent management's best estimate of all valid
         claims.  Such claims remain subject to future adjustments
         depending on negotiations and actions of the Bankruptcy Court,
         further developments with respect to the disputed claims, whether
         or not such claims are secured, the value of any security
         interests securing any of such claims, and other events.

         11.  INCOME TAXES

         A reconciliation between the amount of reported income tax
         expense/(benefit) and the amount computed using the U.S. federal
         statutory rate of 34% is as follows for the years ended December

         Deferred tax accounting requires that a valuation reserve be
         established if it is more likely than not that all or a portion of
         the deferred tax asset will not be realized.  Accordingly, a
         valuation reserve has been established for the full amount of the
         deferred tax asset.

         As of December 31, 1995, the Company had approximately $58,000,000
         of federal net operating loss (NOL) carryforwards.  These loss
         carryforwards expire through the year 2010.  Utilization of these
         NOL's may be limited pursuant to the provisions of Section 382 of
         the Internal Revenue Code of 1986.  The Company's NOL's are
         subject to review by the Internal Revenue Service and various
         state tax authorities.  In addition, these NOL's and other tax
         attributes may be adversely impacted by the bankruptcy proceedings
         (see Note 1).

         12.  RENTAL AND OTHER INCOME

         The Company receives rental income on certain property and
         equipment from various tenants and sub-tenants under noncancelable
         leases which extend to 1997.  The Company received $286,000 and
         $458,000 in rental income in 1995 and 1994, respectively.  The
         Company records the expenses associated with the rental income by
         aggregating the expenses with the rental income in Other Income/
         Expense on its Statement of Operations.  The Company incurred
         approximately $75,000 and $420,000 in expenses during 1995 and
         1994, respectively, in regard to these leases.  Future minimum
         rentals on noncancelable operating leases for the year ended
         December 31, 1995 are as follows:





                   1996                                      $ 268,840

                                                             =========
         In 1995, the Company received stock valued at $216,000 as a result
         of the demutualization of the Company's ownership position in one
         of its employee benefit providers.  The stock was valued at fair
         market value at the date of receipt.

         13.  COMMITMENTS AND CONTINGENCIES

         Leases - The Company has entered into operating lease agreements
         for its executive offices, warehouse, research laboratories,
         manufacturing facilities, and office equipment.  The base lease
         periods range from two to ten years.  Two leases contain renewal
         options, the first for one five-year period and the second for two
         five-year periods.  Several leases contain escalation clauses for
         increases in real estate taxes from the base year, as well as
         minimum rental increases for the change in the Price Index, not to
         exceed 3% of the previous year's rent.  Costs incurred under the
         operating leases are recorded as rent expense and totaled
         $1,161,000 and $1,406,000 for real estate and $9,400 and $632,000
         for equipment in 1995 and 1994, respectively.

         As of December 31, 1995, the future minimum lease payments
         required under operating leases that have initial or remaining
         noncancelable lease terms in excess of one year are as follows:

         Employment and Consulting Agreements - The Company has agreements
         with various consultants and key employees, with terms ranging,
         generally, from one to three years.  These agreements provide for
         future aggregate annual payments of approximately $916,000.  Costs
         incurred and charged to operations under these contracts
         aggregated $1,422,000 and $2,724,000 in 1995 and 1994,
         respectively.

         Other Agreements - The Company has entered into various license
         agreements which require the Company to pay royalties based upon a
         set percentage of product sales subject, in some cases, to certain
         minimum annual amounts; these minimums total approximately
         $250,000.  Total royalty expense was $1,707,000 and $1,109,000 in
         1995 and 1994, respectively.





         Contingencies - During 1992, the Company paid $2,300,000 to Alfa-
         Laval, a Swedish company, to acquire its fibronectin binding
         technology for use in mastitis vaccines and certain other
         products.  In 1995 the Company recorded $700,000 in expenses for
         the granting of certain patents on this technology.  The agreement
         provides for additional payments to Alfa-Laval conditioned upon
         the first commercial sale of future vaccines at  $1,333,000 per
         vaccine, and up to $1,300,000 conditioned upon the granting of
         additional patents in the United States and Europe on the
         technology acquired.  

         In November 1993, five civil actions were commenced in the United
         States District Court, District of Massachusetts, against the
         Company, certain of its officers, and in three of the actions, the
         Company's former auditors.  The actions were instituted by persons
         alleging to be shareholders of the Company and to be
         representative of a class of shareholders claiming damages
         resulting from alleged violations of securities laws by defendants
         in connection with the 1992 results of the Company and the
         restatement thereof.  The actions have been consolidated under the
         caption In Re: Cambridge Biotech Corporation Securities
         Litigation, Civil Action No. 93-12486-REK.  In February, 1996 the
         plaintiffs agreed to settle all claims against the Company and the
         individual defendants and pleadings were filed with the United
         States District Court for the District of Massachusetts for the
         purpose of approving the settlement.  Under the terms of the
         Settlement, the class members will be entitled to receive their
         pro rata share of: 25% of the shares of a new company which will
         be formed under "the Company's" Chapter 11 reorganization plan,
         and 90% of any recoveries from prosecution of claims, if any,
         against  the Company's former accountants.  The Company shall be
         entitled to receive 10% of any recoveries from prosecution of such
         claims.  These agreements preliminarily have been approved by the
         United States District Court and will be incorporated into the
         Company's plan of reorganization.  The settlement is subject to
         the confirmation of a plan of  reorganization by the U.S.
         Bankruptcy Court.





         In March 1995, an Adversary Proceeding No. 95-4074 was commenced
         in the Bankruptcy court, by Institut Pasteur and Genetic Systems
         Corporation alleging patent infringement and asking for damages
         and injunctive relief.  The Company filed an answer and
         counterclaim denying the plaintiff's allegations and alleging a
         breach by Institute Pasteur of its license agreement with the
         Company.  On September 1, 1995, the Bankruptcy Court issued a
         summary judgment upholding the Company's license under two patents
         issued to Institut Pasteur to commercialize diagnostics tests for
         the HIV-2 strain of the AIDS virus.  The Bankruptcy Court also
         ruled that the Company's HIV-1 Western blot confirmatory test
         infringes a third patent issued to Institut Pasteur, and enjoined
         the Company from the manufacture and sale of the HIV-1 Western
         blot test.  On January 5, 1996, the Bankruptcy Court lifted its
         injunction with respect to the Company's production and sale of
         the HIV-1 Western blot kits.  The Court ruled that the Company has
         a license for the HIV-1 patent and must pay a royalty on related
         sales.  Institut Pasteur has appealed the Bankruptcy's Court's
         ruling.  While the final outcome of these patent issues  cannot be
         determined with certainty, if the Bankruptcy Court rulings are
         sustained, management believes that the outcome will not have a
         material adverse effect on the Company's results of operations or
         its financial position.

         In July of 1994, the Securities and Exchange Commission issued an
         Order Directing Private Investigation in the matter of Cambridge
         Biotech Corporation, investigating matters pertaining to the
         Company's financial statements, its public filings and the
         offerings of its securities.  The Company is cooperating fully
         with the investigation which is ongoing.

         GRF Corporation (see Note 5) is conducting a pilot clinical study
         testing the use of growth hormone releasing factor to treat
         osteoporosis.  Depending on the results of the pilot study, the
         Company has the right to fund additional studies and potentially
         increase its equity interest in the joint venture.  While growth
         hormone levels have increased in the majority of the patients in
         response to treatment, the data are incomplete.

         The Company has and is engaged in negotiations of various
         contracts, license agreements and other claims with other parties
         regarding issues generally incidental to the normal course of
         business.  While the outcome of these negotiations and the
         ultimate liability from these discussions is difficult to
         determine, in the opinion of management any additional liability
         will not have a material effect on the Company's financial
         position, liquidity, or results of operations.

         14.  CAPITALIZATION OF COMPANY

         Effective upon the Company's reorganization under Chapter 11, all
         outstanding stock options, except for options on 1,313,000 shares
         granted in December 1995, will be cancelled.  





         Capital Stock - In the first quarter of 1994 the Company issued
         2,589,000 shares in connection with a shelf offering.  The
         offering raised net proceeds of $6,635,000 after deducting legal
         costs and other expenses associated with the offering.

         Stock Option and Purchase Plans - The Company  has three stock
         option plans.  A plan adopted in 1985 and amended in 1987 provides
         for non-qualified stock options and stock appreciation rights
         available only to non-employee consultants.   A stock option plan
         adopted in 1989 and amended in 1991 provides the granting of
         incentive stock options to employees and non-qualified stock
         options, discounted stock options, restricted stock, deferred
         stock and stock appreciation rights to employees, officers,
         consultants and advisors.  A stock award and option plan for
         directors was adopted November 19, 1991 and subsequently approved
         at the shareholders' annual meeting on May 19, 1992.  The plan
         provides for the granting of incentive stock options, restricted
         stock, deferred stock and stock appreciation rights to directors.
         No stock appreciation rights or deferred stock  had been granted
         through December 31, 1995.

         On November 19, 1991, the Company's Board of Directors approved a
         program, which was ratified by the Company's shareholders in 1992,
         to reserve an additional 3,000,000 shares of common stock for the
         1989 stock option plan.  Under this plan, some of the past and
         current  executives of the Company were granted options by the
         Board of Directors in 1992 to purchase 180,000 shares of common
         stock at 75% of the fair market value at the date of the grant.
         The options vest over a five-year period, but vesting may be
         accelerated upon the attainment of certain goals.  During 1994
         stock options with a deferred compensation balance totaling
         $449,000, were forfeited by employees who left the Company.  In
         1995 and 1994, $49,000 and $160,000 respectively, of deferred
         compensation related to this program was amortized to expense.  On
         December 15, 1995, certain executives and members of the Board of
         Directors were granted options on 1,313,000 shares of common stock
         at $0.37 which vested immediately.  The Company recognized
         $171,000 of compensation expense in connection with the issuance
         of discounted options.

         The above plans provide for the granting of options for an
         aggregate maximum of 5,814,000 shares of common stock and
         2,100,000 stock appreciation rights.  There were 1,853,000 options
         available for granting at December 31, 1995.  The price of the
         shares that may be purchased under the plans shall be determined
         by the Board of Directors, subject to certain limitations.
         Options granted during 1994 generally vest over two to three
         years.  The right to grant options under each plan expires ten
         years after adoption.  A summary of option activity is as follows:





                                       Shares        Prices

         Balance, January 1, 1994       2,907,818    $1.00 to $16.44

         Options granted                  619,000    $1.17 to $3.31

         Options rescinded 
         or lapsed                      (960,789)    $2.00 to $14.06

         Options exercised                (3,000)    $2.00
                                        _________

         Balance, December 31, 1994     2,563,029    $1.00 to $16.44

         Options granted                1,312,500    $0.37

         Options rescinded                       
         or lapsed                      (778,489)    $2.00 to $14.06
                                         ________                     

         Balance, December 31, 1995     3,097,040    $0.37 to $16.44

                                          =======

         There were 3,097,000 options outstanding at December 31, 1995 of
         which 2,696,000 were exercisable.  

         On October 27, 1994, the Company's plan to institute a retention
         bonus plan for some of its employees was approved by the United
         States Bankruptcy Court for the District of Massachusetts.  The
         plan called for bonuses to be paid in stock of the reorganized
         Company upon emergence from Chapter 11 reorganization.  The
         Company recorded compensation expense of $830,000 and $627,000 in
         1995 and 1994, respectively.

         In 1995, the Financial Accounting Standards Board issued Statement
         of Financial Accounting Standards No. 123 ("FAS 123"), "Accounting
         for Stock-Based Compensation".  FAS No., 123 encourages but does
         not require the recognition of compensation expense for grants of
         stock, stock options, and other equity instruments based upon new
         fair value accounting rules (the "recognition method").  Companies
         that choose not to adopt the recognition method must disclose pro-
         forma net income and earnings per share amounts under that method
         and make detailed disclosures about plan terms, exercise prices,
         and assumptions used in measuring the fair value of stock based
         grants (the "disclosure method").  The Company plans to adopt the
         disclosure method in 1996.





         15.  EMPLOYEE BENEFITS PLAN

         The Company has a savings plan for its employees pursuant to
         Section 401(k) of the Internal Revenue Code.  Substantially all
         employees can participate, and the plan allows for a minimum
         deferral of 1% to a maximum deferral of 15% percent of plan
         compensation, as permitted by law or as limited by the plan
         administrator.  Prior to the Chapter 11 filing, the Company
         matched 50% of the first 6% of an employee's compensation, if
         contributed to the plan.  Any contributions made by the Company
         vest over a three-year period.  The amount charged to operations
         for the plan was $93,000 in 1994.  The Company suspended its
         matching contribution on the date of the Chapter 11 filing.

         16.  AGREEMENTS

         The Company has a comprehensive agreement with SmithKline Beecham
         p.l.c. ("SmithKline") which allows SmithKline to use the Company's
         proprietary Stimulon adjuvant ("QS-21") in numerous vaccines
         including hepatitis, lyme disease, human immunodeficiency virus
         (HIV), influenza and malaria.  The agreement grants certain
         exclusive worldwide rights in some fields of use, and co-exclusive
         or non-exclusive rights in others.  The Company recognized
         $3,500,000 and $3,000,000 in license fees under this agreement
         during 1995 and 1994, respectively.  Deferred revenue at December
         31, 1994 was $3,500,000.  The agreement calls for royalties to be
         paid by SmithKline on its future sales of licensed vaccines which
         include CBC's adjuvant.  The terms of the collaborative agreement
         with SmithKline include funding through 1998.

         The Company has product development and supply agreements with
         Virbac S.A. ("Virbac") which covers the ongoing collaboration
         between Virbac and the Company relating to the following products:
         vaccines for the feline leukemia virus ("FeLV"), the feline immune
         deficiency virus ("FIV") and bovine mastitis.  The Company
         recognized $1,464,000 and $1,061,000 in revenues under these
         agreements during 1995 and 1994, respectively.  In addition,
         $2,072,000 and $2,543,000 were included in deferred revenue at
         December 31, 1995 and 1994, respectively.  

         As part of its program to develop, manufacture and market products
         for detection, prevention and treatment of human and animal
         infectious diseases, the Company has entered into various
         agreements with the National Institute of Health (NIH).  Such
         agreements provide the Company with research and development
         funding through 1995, assuming, in certain cases, achievement of
         mutually defined milestones.  Revenue recognized under these
         contracts amounted to $596,000 and $787,000 in 1995 and 1994,
         respectively.





         17.  MAJOR CUSTOMERS

         Ortho Diagnostics Systems, Inc. (Ortho) is the Company's principal
         distributor for retroviral products, which include both screening
         and confirmatory tests.  All of the Company's products marketed by
         Ortho are under a joint Cambridge Biotech / Ortho label.  Sales to
         Ortho represented 30% and 32% of the Company's total revenue in
         1995 and 1994, respectively.

         SmithKline<PAGE>





         is the Company's principle source of research and development
         revenue.  Revenues from SmithKline represented 13% and 14% of the
         Company's total revenue in 1995 and 1994, respectively.

         18.  SEGMENT INFORMATION           

         The Company operates in one industry segment consisting of the
         development, manufacturing and marketing of products for the
         detection, prevention, and treatment of infectious diseases in
         humans and animals.  Export sales were approximately $4 million
         and $3.7 million in 1995 and 1994, respectively.  The Company's
         subsidiary, CAC, operates in Europe and reported sales of
         $2,788,000 and $231,000 in 1995 and 1994, respectively.

        Sublessee.  Sublessee shall also obtain and pay the expense of
        all janitorial services required on the demised premises.

                                   SECTION SIX

                           ACCIDENTAL DAMAGE OR INJURY

             Lessor and lessee shall not be liable for any damage to

                                      - 2 -




        others, caused by conditions or activities on the demised

        or the part so damaged.  If lessor elects to rebuild or repair
        the demised premises and does so without unnecessary delay,
        Sublessee shall be bound by this sublease agreement, except that
        during the period of repair the rent of the demised premises
        shall be abated in the same proportion that the part of the
        demised premises rendered unfit for occupancy by Sublessee shall
        bear to the whole of the subleased premises.  If lessor fails to
        give notice of the intent to repair, Sublessee shall have the

        demised premises in order to conform with this sublease
        agreement.

        Sublessee.

                     ALTERATIONS, ADDITIONS, OR IMPROVEMENTS

             A.   Sublessee shall not make any alterations, additions, or
        improvements on or to the demised premises without first
        obtaining the written consent of lessee.  All alterations,

        sole expense of Sublessee and shall become the property of lessee
        and shall remain on and be surrendered with the demised premises
        as a part thereof at the termination of this sublease agreement
        without disturbance, molestation, or injury.

             B.   Nothing contained in this section shall prevent
        Sublessee from removing all office machines, equipment, and trade
        fixtures customarily used in the business of Sublessee.

                                  SECTION ELEVEN

                                      LIENS

             Sublessee shall keep the demised premises free and clear of
        all liens arising out of any work performed, materials finished,
        or obligations incurred by Sublessee.

                                  SECTION TWELVE

                                ACCESS TO PREMISES

             Sublessee shall allow lessor or lessee or the agents or
        employees of either the free access to the demised premises at
        all reasonable times for the purpose of inspecting or of making
        repairs, additions, or alterations to the demised premises or any
        property owned by or under the control of either party.

                                 SECTION THIRTEEN

                                  ADVERTISEMENTS

             All signs or symbols placed in the windows or doors of the
        demised premises, or on any exterior part of the building by
        Sublessee, shall be subject to the approval of lessee.  If
        Sublessee shall place signs or symbols on the exterior of the
        building or in the windows or doors where they are visible from
        the street that are not satisfactory to lessee, lessee may
        immediately demand the removal of the signs or symbols.  The
        refusal by Sublessee to comply with any demand within a period of
        72 (seventy-two) hours will constitute a breach of this sublease
        agreement and entitle lessee immediately to recover possession of
        the demised premises in the manner provided by law.  Any signs so
        placed on the demised premises shall be so placed on the
        understanding and agreement that Sublessee shall remove these
        signs or symbols at the termination of the tenancy created in and
        by this sublease agreement and repair any damage or injury to the

                                      - 4 -




        demised premises caused thereby.  If not so removed by Sublessee,
        then lessee may have the signs or symbols removed at the expense
        of Sublessee.

                                 SECTION FOURTEEN

                        SALES, ASSIGNMENTS, AND SUBLEASES

             A.   Sublessee shall not assign this sublease agreement, or
        sell or sublet the premises subleased, or any part thereof or
        interest therein, without the prior, express, and written consent
        of lessee.

             B.   This sublease shall not be assigned by operation of
        law.

             C.   If consent is once given by lessee to the assignment of
        this sublease agreement or sublease of the demised premises or
        any interest in this sublease agreement, lessee shall not be
        barred from subsequently refusing to consent to any further
        assignment or sublease.

             D.   Any attempt to sell, assign, or sublet without the
        consent of lessee, shall be deemed a default by Sublessee,
        entitling lessee to reenter pursuant to Section Nineteen if
        lessee so elects.

                                 SECTION FIFTEEN

                                 QUIET ENJOYMENT

             If Sublessee performs the terms of this sublease agreement,
        lessee will warrant and defend Sublessee in the enjoyment and
        peaceful possession of the demised premises during the term of
        this sublease agreement without any interruption by lessee or
        lessor or either of them or any person rightfully claiming under
        either of them.

                                 SECTION SIXTEEN

                                   CONDEMNATION

             A.   If the demised premises or any part of the demised
        premises are appropriated or taken for any public use by virtue
        of eminent domain or condemnation proceedings, or if by reason of
        law, ordinance, or by court decree, whether by consent or
        otherwise, the use of the demised premises by Sublessee for any
        of the specific purposes referred to in this sublease agreement
        shall be prohibited, Sublessee shall have the right to terminate
        this sublease on written notice to lessee, and rental shall be
        paid only to the time when Sublessee surrenders possession of the
        demised premises.



                                      - 5 -




             B.   In the event of partial appropriation, Sublessee may
        elect to continue in possession of that part of the demised
        premises not so appropriated under the same terms and conditions
        of this sublease agreement, except that in those cases Sublessee
        shall be entitled to an equitable reduction of the rental payment
        under this sublease agreement.

             C.   Any rental paid in advance beyond the time that the
        property has been taken from Sublessee shall be returned by
        lessee to Sublessee on demand.

             D.   Sublessee does not waive any right to recover from the
        condemnation authority for any damage that may be suffered by
        Sublessee by reason of any condemnation.

                                SECTION SEVENTEEN

        Sublessee is granted the option and privilege of extending and

        writing of not less than 90 (ninety) days, terminate this
        sublease agreement.

                                 SECTION NINETEEN

                               DEFAULT OF SUBLESSEE

             A.   If any rents reserved, or any part thereof, shall be
        and remain unpaid when they shall become due, or if Sublessee
        violates or defaults in any of the provisions of this sublease
        agreement, then lessee may cancel this sublease agreement by
        giving the required notice, and reenter the demised premises.

             B.   In spite of any reentry, the liability of Sublessee for
        the rent shall not be extinguished for the balance of the term of
        this sublease agreement, and Sublessee shall make good to lessee
        any deficiency arising from a reentry and reletting of the

                               EMPLOYMENT AGREEMENT


             THIS AGREEMENT is made effective as of April 6, 1995 (the
        "Commencement Date") by and between Cambridge Biotech Corporation,
        debtor and debtor in possession United States Bankruptcy Court for
        the District of Massachusetts, Western Division, Case Number 94-
        43054-JFQ, a Delaware corporation, having a principal place of
        business at 365 Plantation Street, Worcester, Massachusetts
        ("CBC") and Alison Taunton-Rigby of 8 Farrar Road, Lincoln,
        Massachusetts 01773 ("Executive").

             WHEREAS, CBC desires to employ Executive for the period and
        upon the terms and conditions provided in this agreement; 

             WHEREAS, Executive desires to serve in the employ of CBC on a
        full-time basis upon the terms and conditions hereinafter
        provided;

             WHEREAS, CBC has filed for protection under the provisions of
        Chapter 11 of the United States Bankruptcy Code, and CBC wishes to
        obtain the approval of the United States Bankruptcy Court for the
        District of Massachusetts, Western Division (the "Court") to the
        consummation of the matters contemplated herein.  

             NOW, THEREFORE, in consideration of the mutual covenants
        herein contained, the parties hereto agree as follows:

             1.   Employment.  CBC hereby employs Executive, and Executive
        hereby accepts employment by CBC, for the period stated in
        Paragraph 3 hereof and upon the terms and conditions herein
        provided.

             2.   Position and Responsibilities; Principal Location.

                  (a)  During the term of this agreement, Executive will
        serve as President and Chief Executive Officer of CBC reporting to
        its board of directors ("the Board").  Executive shall devote her
        primary energies, attention and abilities to the business of CBC
        and shall perform such duties as shall be assigned to her by the
        Board consistent with her status of President and Chief Executive
        Officer.  Executive's duties shall include such duties as are
        customarily associated with the positions of President and Chief
        Executive Officer, including, without limitation, general
        supervision and control over, and responsibility for, the general
        management and operation of CBC and any subsidiaries.  CBC shall
        take all actions necessary to appoint Executive to the Board and
        during the term of Executive's employment, at any time as
        Executive's term as a director of CBC shall be expiring, shall
        nominate and recommend to CBC's stockholders the election of
        Executive as a director of CBC.  CBC acknowledges that Executive
        serves as the President of the Massachusetts Biotechnology Council     
         




        and as a director of the companies listed on Schedule A and
        agrees she may continue to serve in such positions.  With the
        prior approval of the Board, Executive may serve as a director of
        other companies.  Executive understands and agrees that in
        carrying out her responsibilities and performing her duties under
        this agreement she may be required to perform duties and serve in
        administrative or executive capacities for CBC's affiliates.  

                  (b)  The principal location at which Executive will
        perform her duties will be at CBC's principal offices in
        Worcester, Massachusetts or in a location not more than fifty (50)
        miles distant from Boston, Massachusetts.  

             3.   Term of Employment.  The term of Executive's employment
        hereunder shall be for two years from the Commencement Date;
        provided, however, that thereafter the term shall be extended
        automatically on each anniversary of the Commencement Date, for
        one (1) year unless either CBC or Executive shall have given
        written notice to the other of a desire that such automatic
        extension not occur, which notice is given no later than ninety
        (90) days prior to the relevant anniversary of the Commencement
        Date.  The last day of such term as may be extended from time to
        time is herein sometimes referred to as the "Expiration Date."  

             4.   Compensation and Benefits.  For all services rendered by
        Executive during her employment hereunder, CBC shall compensate
        Executive as follows:

                  (a)  Salary.  CBC shall pay Executive a base salary of
        $225,000 per year, subject to increase from time to time in
        accordance with the usual practice of CBC with respect to review
        of compensation of its senior executives.  Executive's salary
        shall be reviewed at least annually.  Executive's salary shall be
        payable in periodic installments in accordance with CBC's usual
        practice for its senior executives.

                  (b)  Regular Benefits.  Executive shall be entitled to
        participate in any and all employee benefit plans, medical
        insurance plans, disability income plans, life insurance plans,
        retirement plans, and other benefit plans from time to time in
        effect for senior executives of CBC, including the Management 
        Bonus Plan subject to the conditions described in Section 4(c)
        below.  Such participation shall be subject to: (i) the terms of
        the applicable plan documents; (ii) generally applicable policies
        of CBC; and (iii) the discretion of the Board or any
        administrative or other committee provided for in or contemplated
        by such plan.  Notwithstanding any other provision of this
        Section 4, Executive shall be entitled to those benefits set forth
        on Schedule B.

                  (c)  Management Bonus Plan.  After having been employed
        for one year hereunder, Executive shall be eligible annually,
        commencing in 1996, to participate in CBC's Management Bonus Plan
        for its executive officers, a copy of which is attached hereto and

                                       - 2 -                                   




        made a part hereof as Schedule C.  Executive's target annual bonus
        shall be 35% of her then annual salary.  The award of any bonus
        shall be in the sole discretion of the Board based upon
        Executive's performance.  Executive may elect to receive in cash
        up to forty percent (40%) of any such bonus which is granted based
        upon Executive's performance in the first year of this contract.
        The shares issuable upon grant of any such bonus are referred to
        herein as the "Bonus Shares."

                  (d)  Business Expenses.  CBC shall reimburse Executive
        for all reasonable travel and other business expenses incurred by
        her in the performance of her duties and responsibilities, subject
        to such reasonable requirements with respect to substantiation and
        documentation as may be specified by CBC.

                  (e)  Vacation.  Executive shall be entitled to paid
        vacation in accordance with the policies of CBC (but in no event
        less than four weeks per year), to be taken at such times and
        intervals as shall be determined by Executive with the approval of
        CBC, which approval shall not be unreasonably withheld.

                  (f)  Life Insurance.  CBC will provide Executive term
        life insurance having death benefits totalling Two Million Dollars
        ($2,000,000), including any benefit to which Executive may be
        eligible under any CBC life insurance plan.  CBC agrees that it
        will "gross-up" Executive's compensation as a result of the
        payment of the premiums for such life insurance by making an
        additional payment to her in an amount which, after reduction for
        any income taxes payable as a result of receiving such additional
        payment, is equal to the income tax payable by Executive as a
        result of the payment by CBC of such premiums.  

             5.   Bonus Option.  

                  (a)  Executive shall be granted an option (the "Bonus
        Option") to purchase that number of shares of common stock
        ("Reorganization Stock") of CBC or its successor issued pursuant
        to CBC's Plan of Reorganization confirmed by the Court (the
        "Plan") having an aggregate value equal to one and one-half
        percent (1.5%) of the value (the "RS Value") of all of CBC's
        Reorganization Stock outstanding on the effective date ("Effective
        Date") of the Plan.  For the purposes of this agreement,  RS Value
        shall be an amount equal to: (i) the value assigned by the Court
        to all of the Reorganization Stock outstanding on the Effective
        Date as contained in the Court's order confirming the Plan; or
        (ii) if the Court does not assign a value to all of the
        Reorganization Stock, the product of the value assigned by the
        Court to each share of the Reorganization Stock outstanding on the
        Effective Date as contained in its order confirming the Plan
        multiplied by the number of shares of Reorganization Stock
        outstanding on the Effective Date; or (iii) if no value is
        assigned by the Court as set forth in (i) or (ii), the value
        assigned by CBC to each share of Reorganization Stock as part of
        the process of confirming the Plan which value is accepted by the

                                       - 3 -                                   




        Court, whichever is applicable.  The value of a share of
        Reorganization Stock determined by or extrapolated from the above
        process is sometimes referred to herein as the "RS Share Value."
        The Bonus Option shall be granted on the Effective Date, shall
        have a term of ten years, shall be a nonqualified stock option,
        and shall be exercisable as to two-thirds of the shares subject to
        the Bonus Option at any time and from time to time commencing on
        the Effective Date.  The Bonus Option as to the remaining one-
        third of the shares (the "Unvested Shares") shall be exercisable
        at any time and from time to time commencing on the earlier of
        (the "Vesting Date"):  (i) the second anniversary date of this
        agreement, (ii) immediately preceding the date on which a Change
        of Control (as hereinafter defined or as defined under CBC's 1989
        Stock Award and Option Plan (the "Option Plan")) is deemed to
        occur, but subject to such Change of Control, provided in the
        event of a Change of Control as a result of a tender offer, such
        Bonus Option shall become fully exercisable in a timely manner
        such that Executive may participate in such tender offer at any
        stage, (iii) the date on which Executive's employment hereunder
        terminates pursuant to the provisions of Section 6(c) or Section
        6(d), or (iv) as provided in the Stock Option Agreement attached
        hereto as Schedule D, upon Executive's death or disability.
        Notwithstanding the foregoing, if prior to the Vesting Date: (i)
        Executive voluntarily ceases to be an employee of CBC (other than
        pursuant to the provisions of Section 6(c)), or (ii) her
        employment is terminated pursuant to the provisions of Section
        6(b) hereunder, the Bonus Option shall not be exercisable as to
        the Unvested Shares.  Upon exercise of the Bonus Option, Executive
        shall make a payment for each share of the Reorganization Stock in
        an amount equal to the RS Share Value.  It is anticipated that CBC
        will grant the Bonus Option under the Option Plan, and the parties
        will execute a Stock Option Agreement on substantially the terms
        set forth in Schedule D attached hereto and made a part hereof,
        and the terms of such agreement shall govern the terms of the
        Bonus Option.  

                  (b)  Commencing in 1996, Executive shall be eligible for
        consideration for option grants made by CBC's Compensation
        Committee as made annually by such committee in such amount and on
        such terms as the Compensation Committee may determine.

                  (c)  CBC and Executive acknowledge that CBC is
        currently unable to comply with the provisions of the Securities
        Exchange Act of 1934, as amended, with respect to periodic filings
        nor with the provisions of the Securities Act of 1933, as amended
        and the regulations thereunder, (the '33 Act) pertaining to the
        registration of securities for public sale due, in both instances,
        to its inability to provide audited financial statements for
        fiscal years 1992, 1993 and 1994.  Although CBC's current
        intention is to engage an auditing firm to conduct an audit of the
        Company's financial statements for fiscal year 1994, CBC has not,
        as of the date hereof, obtained approval from the Court to retain
        an audit firm to conduct such audit, and CBC is continuing to
        evaluate the feasibility and advisability of having an audit

                                       - 4 -                                   




        conducted of its financial statements for fiscal years 1992 and
        1993.  CBC agrees to use all reasonable efforts to insure as soon
        as is reasonably practicable taking into account its current
        inability to provide audited financial statements, that any Bonus
        Shares issued hereunder and any shares issued upon the exercise of
        the Bonus Option will be freely tradeable by Executive under the
        provisions of the '33 Act without restriction, except such
        restrictions as are imposed upon affiliates as a result of their
        status as such. 

                  (d)  CBC agrees to use its reasonable efforts to
        establish and maintain a cashless exercise program which will
        apply to options granted by CBC to Executive.

                  (e)  CBC agrees that with respect to all options and
        Bonus Shares, upon grant and during the term of such options and
        the issuance of the Bonus Shares, CBC shall use reasonable efforts
        to comply with the requirements of Rule 16b-3, promulgated
        pursuant to the Securities Exchange Act of 1934, as amended, as
        such rule shall be in effect from time to time, or with any
        successor provisions ("Rule 16b-3") such that such options and
        Bonus Shares shall be afforded the benefits of Rule 16b-3. 

             6.   Termination and Termination Benefits.  Notwithstanding
        the provisions of Section 3, Executive's employment hereunder
        shall terminate under the following circumstances:

                  (a)  Death.  In the event of Executive's death during
        Executive's employment hereunder, CBC shall continue to pay an
        amount equal to Executive's base salary to Executive's beneficiary
        designated in writing to CBC prior to her death (or to her estate,
        if she fails to make such designation) for a period of six (6)
        months after the date of Executive's death, at the salary rate in
        effect on the date of her death, said payments to be made on the
        same periodic dates as base salary payments would have been made
        to Executive had she not died.

                  (b)  Termination by CBC for Cause.  Executive's
        employment hereunder may be terminated by CBC for cause, without
        further liability on the part of CBC, effective immediately by
        notice to Executive stating the nature of such cause.  The
        following shall constitute "cause" for such termination:

                       (i)   Deliberate dishonesty of Executive with
        respect to CBC or any subsidiary or affiliate thereof; or

                       (ii)  Conviction of Executive of a crime involving
        moral turpitude; or

                       (iii) The material failure by Executive to perform
        Executive's duties hereunder (other than any such failure
        resulting from the incapacity of Executive due to physical or
        mental illness) which failure continues for thirty (30) days after


                                       - 5 -                                   




        notice to Executive setting forth in reasonable detail the manner
        in which Executive has not performed Executive's duties; or

                       (iv)  Unlawful conduct pertaining to CBC or any of
        its affiliates or shareholders or involving a criminal act;
        material and conscious falsification or unauthorized disclosure of
        important records or reports; embezzlement or unauthorized
        conversion of property; violation of conflict of interest or
        vendor relations policies; or willful disclosure of significant
        trade secrets or other information likely to be used to the
        detriment of CBC.  

                  (c)  Termination by Executive for Cause.  Executive's
        employment hereunder may be terminated without liability effective
        after thirty (30) days notice by Executive to CBC in the event of
        the following:

                       (i)   Material breach by CBC of this agreement if
        such breach shall continue for more than thirty (30) days after
        notice to CBC setting forth in reasonable detail the nature of
        such breach; or

                       (ii)  Executive should fail to be elected to the
        Board or to the office of President or Chief Executive Officer or
        at any time fail to remain on the Board or in either of such
        offices, except such failure which is caused by Executive's
        voluntary resignation from such offices; or 

                       (iii) A significant decrease in the nature and
        scope of Executive's authority, powers, functions or duties from
        the authority, powers, functions and duties exercised by Executive
        (collectively a "Terminating Event") as of the date of Court
        approval of this agreement or, if such decrease occurs after the
        Effective Date, as of the day after the Effective Date.
        Notwithstanding the foregoing, no notice to terminate may be given
        pursuant to this clause (iii) after the passage of six months from
        the occurrence of a Terminating Event; or

                       (iv)  The Plan is confirmed by the Court over the
        objection of CBC, provided that no notice to terminate may be
        given pursuant to this clause (iv) after the passage of sixty (60)
        days from the Effective Date.

                  (d)  Termination by CBC Without Cause.  Executive's
        employment may be terminated without cause by CBC by thirty (30)
        days notice to Executive.

                  (e)  Termination of Executive Without Cause.  Executive
        may terminate her employment under this Section 6(e) without
        liability by notice given no earlier than the first anniversary of
        the Commencement Date to be effective no earlier than ninety (90)
        days after such notice.

                  (f)  Certain Termination Benefits.  

                       (i)  In the event of termination pursuant to
        Section 6(c)(i), (ii), (iii) or (iv) or Section 6(d), CBC shall
        continue to pay Executive base salary at the rate in effect on the
        date of termination for the period subsequent to the date of
        termination until the later to occur of the Expiration Date or the
        first anniversary date of the termination.  

                       (ii)  Notwithstanding the provisions of clause
        6(f)(i) or 6(f)(iv)(B), if a termination under either
        Section 6(c)(i), (ii) or (iii) or 6(d) above shall occur within
        six (6) months after a Change of Control, CBC shall pay Executive
        within fifteen (15) days of such termination, in lieu of the
        payments set forth in clause 6(f)(i) and 6(f)(iv)(B), an amount
        equal to two (2) times Executive's base salary at the annual rate
        as in effect immediately prior to such Change of Control, but in
        no event less than two (2) times the annual rate set forth in
        Section 4(a).  "Change of Control" shall mean:  (i) the
        acquisition by any individual, firm, corporation, partnership or
        other entity (excluding CBC, any of CBC's employee benefit plans
        or the plaintiffs, as a class, under the action pending in the
        United States District Court for the District of Massachusetts
        captioned In re Cambridge Biotech Corporation Securities
        Litigation) of thirty percent (30%) or more of the shares of
        Reorganization Stock then outstanding; (ii) a change in the
        majority of the Board (excluding any persons approved by a vote of
        at least a majority of the current Board); or (iii) the approval
        by the stockholders of a merger, consolidation (other than a
        merger or consolidation in which stockholders of the Company
        receive fifty percent (50%) or more of the stock of the surviving
        company), or a liquidation, dissolution or the sale of all or
        substantially all of the assets of CBC.

                       (iii) In the event of a termination pursuant to
        Section 6(c)(i), (ii), (iii) or (iv) or 6(d), then Executive shall
        continue to receive the benefits to which she is entitled under
        Section 4(b) and Section 4(c) as of immediately preceding such
        termination at CBC's expense for the period of time during which
        Executive remains entitled to receive continuing payments as
        provided in Section (f)(i) above or Section (f)(iv)(B) below, as
        the case may be, , or two years, in the case of a termination to
        which Section (f)(ii) applies (notwithstanding the provisions of
        Section 6(f)(iv)(B) below); provided that Executive shall only be
        eligible for an award under the plan described in Section 4(c) for
        the period prior to her termination and awards thereunder shall be
        prorated through the date of termination; and provided further,
        CBC's obligation to continue such benefits shall cease on a
        benefit by benefit basis on that date, if any, on which Executive
        is employed on a full-time basis and Executive receives in
        connection with such employment benefits which are substantially
        equivalent to CBC's benefits.  For purposes of the application of
        CBC's benefits, Executive shall be treated, to the extent that
        applicable law pertaining to the particular CBC benefit plan

                                       - 7 -                                   



        permits CBC to do so, as if she had remained in the employ of CBC,
        with a total annual salary at the rate in effect on the date of
        termination and service or similar credits, if any, will continue
        to accrue during such period as if the Executive had remained in
        the employ of CBC.  If in spite of the provisions of this clause
        (iii), benefits or service credits under any benefit plan shall
        not be payable or provided under any such plan to the Executive,
        or to Executive's dependents, beneficiaries or estate, because
        Executive is no longer deemed to be an employee of CBC, CBC itself
        shall pay or provide payment of such benefits and service credits
        for such benefits to the Executive, or to the Executive's
        dependents, beneficiaries or estate.  To the extent that
        applicable law does not permit any CBC benefit referred to above
        to be provided, paid or funded through the applicable CBC benefit
        plan, then CBC shall not be required to provide such benefit
        through such plan and shall only be required to provide in the
        case of a benefit the tax treatment of which is enhanced by such
        plan an amount equal to what would have been the Company's initial
        contribution to such plan and not the equivalent benefit.

                       (iv)  (A)  If CBC shall give notice under Section 3
        that it does not desire to extend the term of Executive's
        employment hereunder, then, except as hereinafter set forth in
        clause (B), for all purposes such a termination shall be treated
        as a termination by CBC without cause under Section 6(d);  (B)
        notwithstanding the foregoing provisions of clause (A), in lieu of
        the termination benefits that otherwise would be provided under
        Section 6(f)(i) and Section 6(f)(iii), CBC shall continue to pay
        Executive base salary at the rate in effect on the date of
        termination and Executive shall continue to receive the benefits
        to which she is entitled under Section 6(f)(iii) as of immediately
        preceding such termination at CBC's expense for a period of six
        months from the date of expiration of the term of Executive's
        employment hereunder.

                       (v)   Notwithstanding anything contained herein to
        the contrary, the termination by Executive pursuant to Section
        6(e) shall not be deemed to entitle Executive to any termination
        benefits under this Section 6.

             7.   Disability.  If, due to physical or mental illness,
        Executive shall be disabled so as to be unable to perform
        substantially all of her duties and responsibilities hereunder,
        CBC may designate another executive to act in her place during the
        period of such disability.  Notwithstanding any such designation,
        Executive shall continue to receive her full salary and benefits
        under Section 4 of this agreement, unless her employment is
        terminated as provided in this Section 7.  If Executive shall
        become totally and permanently disabled, then CBC may terminate
        Executive's employment hereunder and shall continue to pay to
        Executive her full salary and provide her with the benefits she
        was receiving immediately prior to such termination for one (1)
        year, provided that such salary amounts shall be reduced by the
        amount of any disability insurance proceeds actually paid to

                                       - 8 -                                   



        Executive or for her benefit with respect to such period of time
        under any disability policy provided by CBC for Executive.  The
        determination that by virtue of total and permanent disability,
        Executive is unable to perform her duties hereunder, shall be made
        by a physician chosen by CBC and reasonably satisfactory to
        Executive (or Executive's legal representative) and such
        determination shall be conclusive.  The cost of such examination
        shall be borne by CBC.  Executive shall be conclusively presumed
        to be totally and permanently disabled if for reasons involving
        physical or mental illness or injury Executive fails to perform
        her duties hereunder for a period of one hundred twenty (120)
        consecutive calendar days or for any periods aggregating one
        hundred twenty (120) days or more in any six (6) consecutive month
        period.  The date of termination of Executive's employment
        hereunder in the event of total and permanent disability shall be
        the earlier of such physician's examination pursuant to which such
        determination is made or the first business day after which either
        such 120-day or such six-month period has expired. 

             8.   Non-Competition and Confidential Information.  

                  (a)  Non-competition.  Executive agrees that she will
        not at any time during her employment with CBC, and for a period
        of six months following the termination of such employment for any
        reason, directly or indirectly, as a partner, officer, director,
        consultant, employee, stockholder or otherwise, engage in any
        employment, pursuit or association in which she shall have
        substantial responsibility with respect to products and/or
        services which are in direct competition with products and/or
        services of CBC in the area of diagnostics or adjuvants, or in any
        other specific area constituting more than 40% of CBC's
        consolidated operating revenue at the time of such termination,
        unless CBC was not engaged in the business of diagnostics or
        adjuvants at the time of such termination; provided, however, in
        any event that the holding by Executive of any investment in any
        security shall not be deemed to be a violation of this Section 8
        if such investment does not constitute more than 5% of the
        outstanding issue of such security.

                  (b)  Confidential Information; Inventions; Non-
        Disclosure.  Contemporaneously with the execution of this
        agreement and in consideration thereof, Executive will sign CBC's
        Invention and Non-Disclosure Agreement attached hereto as
        Schedule E.

                  (c)  Relief; Interpretation.  Executive agrees that CBC
        shall be entitled to injunctive relief for any breach by her of
        the covenants contained in Section 8(a) or in the Invention and
        Non-Disclosure Agreement referred to in Section 8(b).  In the
        event that any provision of this Section 8 shall be determined by
        any court of competent jurisdiction to be unenforceable by reason
        of its being extended over too great a period of time, too large a
        geographic area, or too great a range of activities, it shall be
        interpreted to extend only over the maximum period of time,

                                       - 9 -                                   



        geographic areas, or range of activities as to which it may be
        enforceable.  For purposes of this Section 8, the term "CBC" shall
        mean CBC and any of its subsidiaries.

             9.   Conflicting Agreements.  Executive hereby represents and
        warrants that the execution of this agreement and the performance
        of her obligations hereunder will not breach or be in conflict
        with any other agreements to which she is a party or is bound, and
        that she is not now subject to any covenants against competition
        or similar covenants which would affect the performance of her
        obligations hereunder.

             10.  Withholding.  All payments made by CBC under this
        agreement shall be net of any tax or other amounts required to be
        withheld by CBC under applicable law.

             11.  Arbitration of Disputes.  Any controversy or claim
        arising out of or relating to this agreement or the breach thereof
        shall be settled by final and binding arbitration in accordance
        with the laws of The Commonwealth of Massachusetts by three
        arbitrators.  The party initiating arbitration shall nominate one
        arbitrator in the request for arbitration and the other party
        shall nominate a second in the answer thereto within thirty (30)
        days of receipt of the request.  The two arbitrators so named will
        then jointly appoint the third arbitrator.  If the answering party
        fails to nominate its arbitrator within the thirty (30) day
        period, or if the arbitrators named by the parties fail to agree
        on the third arbitrator within sixty (60) days, then such
        arbitrator shall be appointed by the American Arbitration
        Association in the City of Boston.  Such arbitration shall be
        conducted in the City of Worcester, Massachusetts in accordance
        with the rules of the American Arbitration Association, except
        with respect to the selection of arbitrators which shall be
        provided in this Section 11.  Judgment upon the award rendered by
        the arbitrators may be entered in any court having jurisdiction
        thereof.

             12.  Directors and Officers Indemnification.  CBC confirms
        that it will indemnify Executive and advance expenses in
        connection therewith, subject to the requirement that Executive
        repay CBC for such advance if it should be determined that
        Executive is not entitled to indemnification, as provided in the
        Indemnification Agreement attached as Schedule F and to the full
        extent permitted by Delaware General Corporation Law.  CBC will
        provide Executive with directors and officers liability insurance
        protection if and to the extent such coverage is reasonably
        available to CBC.  

             13.  Assignment; Successors and Assigns, etc.  Neither CBC
        nor Executive may make any assignment of this agreement or any
        interest herein, by operation of law or otherwise, without the
        prior written consent of the other party; provided, however, that
        CBC may assign its rights under this agreement without the consent
        of Executive in the event CBC shall hereafter, consolidate with or

                                      - 10 -                                   



        merge into any other person, or transfer all or substantially all
        of its properties or assets to any other person.  In the event of
        Executive's death prior to the completion by CBC of all payments
        due her under this agreement, CBC shall continue such payments to
        the Executive's beneficiary or beneficiaries designated in writing
        to CBC prior to her death (or to her estate, if no designation is
        made).  This agreement shall inure to the benefit of and be
        binding upon CBC and Executive, their respective successors,
        executors, administrators, heirs and permitted assigns.

             14.  Legal Fees.  CBC shall pay Executive's legal fees and
        expenses incurred in connection with entering into this Agreement
        and the related agreements, not to exceed $4,000.

             15.  Publicity.  Neither party shall issue any press releases
        or otherwise make any public statement with respect to Executive's
        employment by CBC without the prior written consent of the other
        party, except as may be required by law, including without
        limitation, the Securities Exchange Act of 1934 and in connection
        with the proceedings before the Court.

             16.  Enforceability.  If any portion or provision of this
        agreement shall to any extent be declared illegal or unenforceable
        by a court of competent jurisdiction, then the remainder of this
        agreement, or the application of such portion or provision in
        circumstances other than those as to which it is so declared
        illegal or unenforceable, shall not be affected thereby, and each
        portion and provision of this agreement shall be valid and
        enforceable to the fullest extent permitted by law.

             17.  Waiver.  No waiver of any provisions hereof shall be
        effective unless made in writing and signed by the waiving party.
        The failure of any party to require the performance of any term or
        obligation of this agreement, or the waiver by any party of any
        breach of this agreement, shall not prevent any subsequent
        enforcement of such or any other term or obligation or be deemed a
        waiver of any subsequent breach.

             18.  Notices.  All notices and other communications required
        or permitted hereunder shall be in writing and shall be delivered,
        mailed by first-class mail, postage prepaid, or sent by telex or

             THIS AGREEMENT is entered into as of this _______  day of
        ____________, 19___ by and between CAMBRIDGE BIOTECH CORPORATION,
        a Delaware corporation with its principal office at 365
        Plantation Street, Worcester, Massachusetts 01605 (hereinafter
        the "Company") and Alison Taunton-Rigby, an individual and
        executive officer of the Company (hereinafter the "Optionee").

             WHEREAS, the Optionee renders important services to the
        Company, and the Company desires to retain the services of the
        Optionee and grant a stock option to the Optionee on the terms
        and subject to the conditions set forth herein and in the
        Company's 1989 Stock Award and Option Plan (the "Plan"); and 

             WHEREAS, the Optionee and the Company have entered into an
        Employment Agreement (the "Employment Agreement") effective
        April 6, 1995, under which this agreement is contemplated.

             NOW, THEREFORE, in consideration of the foregoing and the
        mutual agreements herein contained, the parties hereto hereby
        agree as follows:

             1.   Grant of Option.  The Company hereby grants to the
        Optionee the right, privilege and option (the "Option") to
        purchase from the Company, upon the terms and conditions
        hereinafter set forth, the number of shares of the Company's
        common stock, $.O1 par value, as presently constituted, as are
        set forth on Schedule I attached hereto (the "Option Stock").
        Subject to the restrictions on exercise set forth on Schedule 1,
        the Option may be exercised by the Optionee (which term may
        include his personal representative), in whole or in partial
        increments of shares, at such time or times during the term of
        the Option, by the delivery to the Company of written notice of
        the Optionee's election to exercise the Option, specifying the
        date and number of shares to be purchased, together with the
        Exercise Price which is specified on Schedule I for each share of
        Option Stock to be purchased, payable by (a) cash, (b) check, (c)
        delivery and assignment to the Company of securities of the
        Company having a value equal to the Exercise Price or (d) by a
        combination of (a), (b) and (c).  The Company shall within a
        reasonable time after receipt of the Exercise Price deliver to
        the Optionee a certificate representing the shares of Option
        Stock so purchased; provided, however, that if any securities law
        or regulation then in effect requires the Company to take any
        action with respect to the Option Stock before the issuance or
        sale thereof by the Company to the Optionee, the date of delivery
        of the certificate shall be extended for the period of time




        necessary to take such action, and the Company shall use its best
        efforts to accomplish such action as promptly as possible.

             2.   Term of Option.  To the extent vested, as set forth on
        Schedule I attached hereto, the Option shall be immediately
        exercisable in full or in part and shall remain exercisable until
        it expires 10 years from the date hereof, unless the Option is
        sooner terminated as hereinafter provided.

             3.   Other Conditions and Limitations.

                  (a)  During the Optionee's lifetime, the Option is
             exercisable only by the Optionee.  The Option may not be
             transferred or assigned, except by will or the laws of
             descent and distribution.  If the Optionee voluntarily
             ceases to be an employee of the Company (other than pursuant
             to Section 6(c) of the Employment Agreement) or if such
             employment is terminated for cause, the Optionee may
             exercise, within three months after the termination date,
             the unexercised portion of the Option in full or in part,
             but only to the extent that the Option was exercisable,
             pursuant to Schedule I, at the date of such termination.  No
             further portion of the option shall become exercisable after
             such employment termination.  If the Optionee's employment
             is terminated involuntarily and without cause; if a Change
             of Control shall occur, as defined in the Plan or as defined
             in the Employment Agreement; or if Optionee shall terminate
             her employment pursuant to Section 6(c) of the Employment
             Agreement, then the Option shall become fully exercisable
             without regard to the limitations of Schedule I and the
             Optionee may exercise the unexercised portion of the Option
             in full or in part within twelve months after the
             termination date, provided that in the case of a Change of
             Control, this option shall become exercisable immediately
             prior to, but subject to, such Change of Control and in the
             event of a Change of Control as a result of a tender offer,
             this option shall become fully exercisable in a timely
             manner such that Executive may participate in such tender
             offer at any stage.  If the Optionee's employment is
             terminated due to disability or death, the Option shall
             become fully exercisable without regard to the limitations
             of Schedule I and the Optionee may exercise the unexercised
             portion of the Option in full or in part within 12 months
             after the termination date.  For the purposes of the
             provisions of this subparagraph, employment with the Company
             shall be considered to continue during the period of time
             the Optionee continues to be associated with the Company in
             the capacity of a consultant or advisor, or the Optionee
             otherwise provides services or assistance to the Company,
             unless and until the Board shall determine, in its
             discretion, that such activity shall no longer be considered
             employment, in which event the Optionee may exercise the
             non-exercised portion of the Option in full or in part but
             only to the extent the Option was exercisable pursuant to

                                       - 2 -




             Schedule I on the date of such determination, within three
             months after receipt by Optionee of notice of such
             determination by the Board.

                  (b)  The Company will furnish upon request of the
             Optionee copies of the certificate of incorporation of the
             Company, as amended, and by-laws of the Company, as amended,
             and such publicly available financial and other information
             concerning the Company and its business and prospects as may
             be reasonably requested by the Optionee in connection with
             the exercise of this Option.

             4.   Securities Law Representation.  The Optionee represents
        and warrants to the Company that (a) the Optionee is acquiring
        the Option for the Optionee's own account for investment, and not
        with a view to, or for resale in connection with, any
        distribution of shares of the Option Stock; and (b) any exercise
        of the Option will constitute the Optionee's representation at
        that time that the Optionee is acquiring the Option Stock for the
        Optionee's own account for investment, and not with a view to the
        distribution thereof.  At the time of the exercise of the Option
        or any installment thereof, the Optionee shall execute such
        further agreement as the Company may require to affirm the
        foregoing representation and to acknowledge the Optionee's
        familiarity with restrictions on the resale of the Option Stock
        under applicable securities laws.

             5.   Stock Dividends; Stock Splits; Stock Combinations;
        Recapitalization.  Adjustment shall be made in accordance with
        the Plan in the maximum number of shares of Option Stock subject
        to this Option and in the number, kind, and option price for
        shares covered by this Option to the extent it is outstanding to
        give effect to any stock dividends, stock splits, stock
        combinations, recapitalizations and other similar changes in the
        capital structure of the Company after the grant of this Option.

             6.   Merger; Sale of Assets; Dissolution.  In the event of a
        change of the Company's capital stock resulting from a merger or
        similar reorganization as to which the Company is the surviving
        corporation, the number and kind of shares then subject to this
        Option and the price per share thereof shall be appropriately
        adjusted in such manner as the Board of Directors of the Company
        may deem equitable to prevent substantial dilution or enlargement
        of the rights available or granted hereunder.  If the Company is
        merged into or consolidated with another corporation under
        circumstances where the Company is not the surviving corporation,
        or if the Company is liquidated, or sells or otherwise disposes
        of substantially all its assets to another corporation, unless
        the unexercised portion of the Option is canceled by action of
        the Board of Directors as of the effective date of such merger
        after notice of at least thirty (30) days prior to the effective
        date of such merger, consolidation, liquidation or sale, the
        Optionee shall be entitled, upon exercise of such Option after
        the effective date of such merger, consolidation, liquidation or

                                       - 3 -




        sale, to receive, in lieu of shares of Option Stock, shares of
        such stock or other securities as the holders of shares of the
        Company's common stock, $.O1 par value, received pursuant to the
        terms of the merger, consolidation, liquidation or sale; and the
        Board of Directors may waive any limitations set forth in
        Schedule I so that the Option, from and after a date prior to the
        effective date of such merger, consolidation, liquidation or
        sale, as the case may be, specified by the Board of Directors,
        shall be exercisable in full.  The Board of Directors as of the
        effective date of any such merger, consolidation, liquidation or
        sale may cancel this Option to the extent then unexercised
        provided that notice of such cancellation shall be given to the
        Optionee and the Optionee shall have the right to exercise such
        Option in full without regard to any limitations set forth in
        Schedule I during a 30-day period preceding the effective date of
        such merger, consolidation, liquidation, or sale.

             7.   Notices.  All notices hereunder shall be in writing and
        effective when delivered or mailed (certified, return receipt
        requested), if to the Company, to:

                  Cambridge Biotech Corporation
                  365 Plantation Street
                  Worcester, MA 01605
                  Attention: Secretary

        and if to the Optionee, to the address set forth on Schedule I.

             A party may change its aforesaid address by giving notice to
        the other party pursuant to the foregoing procedure at least ten
        (10) days prior to the effective date thereof.

             8.   Miscellaneous.

                  A.   This Agreement is issued under and pursuant to the
             terms of the Plan, a copy of which may be examined at the
             principal office of the Company.  In the event of any
             inconsistency between the terms of the Plan and the terms of
             this Agreement, the terms of the Plan shall prevail.  All
             the terms and provisions of the Plan are incorporated herein
             by reference and are assented to by the Company by its
             issuance of this Option, and are assented to by the Optionee
             by his acceptance of this Option.

                  B.   This Agreement shall be binding upon the legal
             representatives, heirs, administrators and executors of the
             Optionee and the successors and assigns of the Company.

                  C.   The Optionee shall have no rights as a stockholder
             with respect to the shares subject to the Option until the
             exercise of the Option and the issuance of a stock
             certificate for the shares with respect to which the Option
             shall have been exercised.


                                       - 4 -




                  D.   Nothing herein contained shall impose any
             obligation on the Company or any of its subsidiaries or the
             Optionee with respect to the Optionee's continued employment
             with the Company or any of its subsidiaries.  Nothing herein
             contained shall impose any obligation upon the Optionee to
             exercise the Option.

                  E.   The Option granted hereunder is not an incentive
             stock option under Section 422 of the Internal Revenue Code
             of 1986, as amended, and the Company makes no representation
             as to the tax treatment to the Optionee upon receipt or
             exercise of the Option or sale or other disposition of the
             Option Stock covered thereby.

             9.   Entire Agreement.  This Agreement constitutes the
        entire agreement of the parties as to the subject matter hereof,
        and supersedes all other prior agreements (both oral and written)
        related thereto.

             10.  Headings.  The paragraph headings used in this
        Agreement are for convenience only and shall not control or
        affect the meaning or construction of any of the provisions
        hereof.

             11.  Governing Law.  This Agreement shall be subject to and
        construed in accordance with the laws of the Commonwealth of
        Massachusetts.

             IN WITNESS WHEREOF, the Company has caused this Agreement to
        be executed by As duly authorized officer and the Optionee has
        executed this Agreement, both as of the date first above written.

                          CAMBRIDGE BIOTECH CORPORATION

                      Invention and Non-Disclosure Agreement

             In consideration of my engagement or continued engagement as
        an employee, consultant or otherwise by Cambridge Biotech
        Corporation, a Delaware corporation, (the "Company") and the
        compensation to be paid me by the Company during my engagement, I
        hereby agree as follows:

        1.   Inventions and Patents:

             Any and all inventions, processes, procedures, systems,
        discoveries, designs, configurations, technology, works of
        authorship, trade secrets, and improvements (whether or not
        patentable and whether or not they are made, conceived or reduced
        to practice during working hours or using the Company's data or
        facilities) (hereinafter called "Inventions") which I make,
        conceive, reduce to practice, or acquire during my employment by
        or consultancy with the Company (either solely or jointly with
        others), and which are related to the Company's present or
        planned business, shall be the sole property of the Company and
        shall at all times and for all purposes be regarded as acquired
        and held by me in a fiduciary capacity for the sole benefit of
        the Company.  I hereby assign to the Company, without further
        compensation, all such Inventions and any and all patents,
        copyrights, trademarks, trade names or applications therefore, in
        the United States and elsewhere, relating thereto.

             I shall maintain adequate and current written records of all
        such Inventions (in the form of notes, sketches, drawings and as
        may be specified by the Company), which records shall be
        available to and remain the sole property of the Company at all
        times.

             I will promptly disclose to the Company all such Inventions
        and will assist the Company in obtaining and enforcing for its
        own benefit patents on such Inventions in any country.  Upon
        request, I will execute all applications, assignments,
        instruments and papers and perform all acts, such as the giving
        of testimony in interference proceedings and infringement suits
        or other litigation, necessary or desired by the Company to
        enable the Company, it successors, assigns and nominees to secure
        and enjoy the full benefits and advantages of such Inventions.

             I understand that my obligations under this section will
        continue after the termination of my engagement by the Company
        and that I will perform such obligations without further
        consideration, except for reimbursement or expenses incurred at
        the request of the Company.  I further understand that if I am
        not engaged by the Company as an employee or consultant at the




        time I am requested to perform any obligations under this
        section, I shall receive for such performance reasonable per diem
        fee, as well as reimbursement of any expenses incurred at the
        request of the Company.  In addition, I understand that the
        absence of a request by the Company for information, or for the
        making of an oath, or for the execution of any document shall in
        no way be construed to constitute a waiver of the Company's
        rights under this Agreement.

             I understand that I shall have patent rights in such
        Inventions as set forth in this paragraph.  Beginning one year
        after I have made a disclosure adequate for the filing of proper
        United States patent application for any of such Inventions, or
        (if earlier) six months after the subject matter of the
        disclosure has been published anywhere or placed in public use or
        on sale in the United States, the Company shall advise me on my
        request; whether it intends to file a United States patent
        application for such subject matter.  If on such a request the
        Company advises me that it does not intend to file such an
        application, then, subject to the following provisions, I may
        file such a application (and any corresponding foreign
        application) at my own expense.  The Company, having stated its
        intention to file such an application, fails to do so (through no
        fault of my own or any co-inventor) within the greater of (a) the
        first half of the time interval between its first knowledge of
        such publication, public use or sale and the first anniversary of
        such publication, public use or sale, or (b) a period of thirty
        days after its first knowledge of such publication, public use or
        sale, then, subject to the following provision, I may file such
        an application (and any corresponding foreign patent
        applications) at my own expense during the second half of such
        time interval.  I shall not, however, file any patent application
        under the terms of this paragraph if the filing thereof conflicts
        with any obligations of the Company to any customer.
        Notwithstanding any contrary provision elsewhere in this section,
        but subject to the provisions of Section 4 below, any patent
        application filed by me under the terms of this paragraph and any
        patent issuing on such an application shall be for my own
        benefit, subject to a royalty-free, non-exclusive, License for
        the life of the patent reserved and granted to the Company.  The
        License includes the Company's right to incorporate such subject
        matter in any design submitted by the Company to any customer or
        prospective customer and in any product made by or on behalf of
        the Company or any affiliate of the Company.  Nothing in this
        paragraph shall limit in any way the Company's right to cause to
        be published or be put into public use or on sale the subject
        matter of any disclosure made under this agreement.  I release
        the Company from any claims and liability for any publication,
        public use or sale of such subject matter by any third party
        including the Company's customers or prospective customers.





                                      - 2 -




        2.   Proprietary Information

             I recognize that my relationship with the Company is one of
        high trust and confidence by reason of my access to and contract
        with the trade secrets and confidential and proprietary
        information of the Company.  I will use my best efforts to
        protect the Inventions and any and all confidential, proprietary
        or secret information relating to the Company's products,
        services, clients, customers or business operations or activities
        (collectively called "Proprietary Information").

             I will not during my engagement with the Company or at any
        time thereafter disclose to others or use for my own benefit or
        for the benefit of another any Proprietary Information (whether
        or not learned, obtained or developed solely by me or jointly
        with others).

             My undertakings and obligations under this Section 2 will
        not apply, however, to any such information which:  (a) is or
        becomes in the public domain through no action or failure on my
        part, (b) is generally disclosed to third parties by the Company
        without restriction on such third parties, or (c) is approved for
        release by written authorization of the Board of Directors of the
        Company.

             Upon termination of my engagement or at any other time upon
        request, I will promptly deliver to the Company all notes,
        memoranda, notebooks, drawings, records, reports, files and other
        documents (and all copies or reproductions of such materials) in
        my possession or under my control, whether prepared by me or
        others, which are secret, confidential or proprietary to the
        Company.  I acknowledge that this material is the sole property
        of the Company.

        3.   Absence of Restrictions Upon Disclosure and Competition

             I hereby represent that, except as disclosed in writing to
        the Company, I am not bound by the terms of any agreement with
        any previous employer or other party to refrain from using or
        disclosing any trade secret or confidential or proprietary
        information in the course of my engagement by the Company or to
        refrain from competing, directly or indirectly, with the business
        of such previous employer or any other party, which would affect
        the performance of my obligations hereunder.  I further represent
        that I have given the Company true and correct copies of any and
        all such agreements described above which remain in force and
        affect notwithstanding whether such agreements would affect the
        performance of my obligations hereunder.

             I further represent that my performance of all the terms of
        this Agreement and of my duties as an employee or a consultant to
        the Company does not and will not breach any agreement to keep in
        confidence proprietary information, knowledge or data acquired by
        me in confidence or in trust prior to my employment with the

                                      - 3 -




        Company, and I will not disclose to the Company or induce the
        Company to use any confidential or proprietary information or
        material belonging to any previous employer or others.

        4.   Other Obligations

             I acknowledge that the Company from time to time may have
        agreements with other persons or entities or with the U.S.
        Government, or agencies thereof, which impose obligations or
        restrictions on the Company regarding the confidential nature of
        such work.  I agree to be bound by all such obligations and
        restrictions and to take all action necessary to discharge the
        obligations of the Company.

        5.   Miscellaneous

             The invalidity or unenforceability of any provisions of this
        Agreement shall not affect the validity or enforceability of any
        other provision of this Agreement.

             This agreement supersedes all prior agreements, written or
        oral, between me and the Company relating to the subject matter
        of this Agreement.  This Agreement may not be modified, changed
        or discharged in whole or in part, except by an agreement in
        writing signed by me and the Company.  I agree that any
        subsequent change or changes in my duties, salary or compensation
        shall not affect the validity or scope of this Agreement.

             This Agreement will be binding upon my heirs, and personal
        representatives in their capacity as such and will inure to the
        benefit of the Company and its successors and assigns, provided
        that Section 2 shall be binding upon such heirs, and personal
        representatives only to the extent that they obtain from me
        Proprietary Information of the Company.

             No delay or omission by the Company in exercising any right
        under this Agreement will operate as a waiver of that or any
        other right, except as expressly provided herein.  A waiver or
        consent given by the Company on any one occasion is effective
        only in that instance and will not be construed as a bar to or
        waiver of that or any other right.  A waiver or consent given by
        the Company on any one occasion is effective only in that
        instance and will not be construed as a bar to or waiver of any

        affiliate thereof to whose employ I may be transferred without
        the necessity for any re-execution of this Agreement at the time
        of such transfer.

                            INDEMNIFICATION AGREEMENT


             This Indemnification Agreement, made and entered into as of
        the _____ day of ____________, 1995 ("Agreement"), by and between
        Cambridge Biotech Corporation, a Delaware corporation (the
        "Corporation"), and Alison Taunton-Rigby, residing at 8 Farrar
        Road, Lincoln, Massachusetts 01773 ("Indemnitee"):

             WHEREAS, the Corporation and the Indemnitee have entered
        into an Employment Agreement dated of even date herewith which
        provides for the execution of this Agreement; and

             WHEREAS, the Board of Directors of the Corporation (the
        "Board") has determined that the difficulty of attracting and
        retaining highly competent persons as directors and officers is
        detrimental to the best interest of the Corporation's
        stockholders and that the Corporation should act to provide such
        persons with adequate indemnification against claims and actions
        against them arising out of their service to and activities on
        behalf of the Corporation; and

             WHEREAS, it is reasonable, prudent and necessary for the
        Corporation contractually to obligate itself to indemnify such
        persons to the fullest extent permitted by applicable law so that
        they will serve the Corporation free from undue concern that they
        will not be so indemnified; and

             WHEREAS, Indemnitee is willing to serve the Corporation on
        the condition that she be so indemnified;

             NOW, THEREFORE, in consideration of the premises and the
        covenants contained herein, the Corporation and Indemnitee do
        hereby covenant and agree as follows:

             Section 1.  Services by Indemnitee.  Indemnitee agrees to
        serve as President, Chief Executive Officer and a Director of the
        Corporation.  Indemnitee may at any time and for any reason
        resign from such positions or from any such position (subject to
        any other contractual obligation or any obligation imposed by
        operation of law), in which event the Corporation shall have no
        obligation under this Agreement to continue Indemnitee in any
        such position.

             Section 2.  General.  The Corporation shall indemnify, and
        advance Expenses (as hereinafter defined) to, Indemnitee as
        provided in this Agreement and to the fullest extent permitted by
        applicable law, as the same exists or may hereafter be amended
        (but, in the case of any such amendment, only to the extent that
        such amendment permits the Corporation to provide broader




        indemnification rights than such law permitted the Corporation to
        provide prior to such amendment unless and to the extent such
        amendment prohibits the Corporation from providing the
        indemnification rights provided hereunder).

             Section 3.  Proceedings Other Than Proceedings by or in the
        Right of the Corporation.  Indemnitee shall be entitled to the
        rights of indemnification provided in this Section 3 if, by
        reason of her Corporate Status (as hereinafter defined), she is,
        or is threatened to be made, a party to any threatened, pending,
        or completed Proceeding (as hereinafter defined), other than a
        Proceeding by or in the right of the Corporation.  Pursuant to
        this Section 3, Indemnitee shall be indemnified against Expenses,
        judgments, penalties, fines and amounts paid in settlement
        actually and reasonably incurred by her or on her behalf in
        connection with such Proceeding or any claim, issue or matter
        therein, if she acted in good faith and in a manner she
        reasonably believed to be in or not opposed to the best interests
        of the Corporation, and, with respect to any criminal Proceeding,
        had no reasonable cause to believe her conduct was unlawful.

             Section 4.  Proceedings by or in the Right of the
        Corporation.  Indemnitee shall be entitled to the rights of
        indemnification provided in this Section 4 if, by reason of her
        Corporate Status, she is, or is threatened to be made, a party to
        any threatened, pending or completed Proceeding brought by or in
        the right of the Corporation to procure a judgment in its favor.
        Pursuant to this Section, Indemnitee shall be indemnified against
        Expenses actually and reasonably incurred by her or on her behalf
        in connection with the defense or settlement of such Proceeding
        if she acted in good faith and in a manner she reasonably
        believed to be in or not opposed to the best interests of the
        Corporation.  Notwithstanding the foregoing, no indemnification
        against such Expenses shall be made in respect of any claim,
        issue or matter in such Proceeding as to which Indemnitee shall
        have been adjudged to be liable to the Corporation unless and
        only to the extent that the Court of Chancery of the State of
        Delaware, or the court in which such Proceeding shall have been
        brought or is pending, shall determine upon application that
        despite the adjudication of liability, but in view of ail the
        circumstances of the case, the Indemnitee is fairly and
        reasonably entitled to indemnity for such Expenses which the
        Court of Chancery or such other court shall deem proper.

             Section 5.  Indemnification for Expenses of a Party Who is
        Wholly or Partly Successful; Other Indemnification.

             (a)  Notwithstanding any other provision of this Agreement,
        to the extent that Indemnitee is, by reason of her Corporate
        Status, a party to and is successful, on the merits or otherwise
        in defense of, any Proceedings, she shall be indemnified against
        all Expenses actually and reasonably incurred by her or on her
        behalf in connection therewith.  If Indemnitee is not wholly
        successful in such Proceeding but is successful, on the merits or

                                      - 2 -




        otherwise, as to one or more but less than all claims, issues or
        matters in such Proceeding, the Corporation shall to the extent
        allowed by law indemnify Indemnitee against all Expenses actually
        and reasonably incurred by her or on her behalf in connection
        with each successfully resolved claim, issue or matter.

             (b)  To the maximum extent permitted by applicable law, the
        Indemnitee shall be entitled to indemnification against Expenses
        reasonably incurred by her if, by reason of her Corporate Status,
        she is involved, as a witness or otherwise, in any threatened,
        pending or completed Proceeding to which she neither is, nor is
        threatened to be made, a party.

             Section 6.  Advancement of Expenses.  The Corporation shall
        advance all reasonable Expenses incurred by or on behalf of
        Indemnitee in connection with any Proceeding within 20 days after
        the receipt by the Corporation of a statement or statements from
        Indemnitee requesting such advance or advances from time to time,
        whether prior to or after final disposition of such Proceeding.
        Such statement or statements shall reasonably evidence the
        Expenses incurred by Indemnitee and shall include or be preceded
        or accompanied by an undertaking by or on behalf of Indemnitee to
        repay any Expenses advanced if it shall ultimately be determined
        that Indemnitee is not entitled to be indemnified against such
        Expenses.

             Section 7.  Procedure for Determination of Entitlement to
        Indemnification.

             (a)  Subject to Section 9, to obtain indemnification under
        this Agreement, Indemnitee shall submit to the Corporation a
        written request, including therein or therewith such
        documentation and information as is reasonably available to
        Indemnitee and is reasonably necessary to determine whether and
        to what extent Indemnitee is entitled to indemnification.  The
        Secretary of the Corporation shall, promptly upon receipt of such
        a request for indemnification, advise the Board of Directors in
        writing that Indemnitee has requested Indemnification.

             (b)  Subject to Section 9, Indemnitee's entitlement to
        indemnification under any of Sections 3, 4 or 5 hereof shall be
        determined in the specific case: (i) if a Change of Control (as
        defined in the Employment Agreement dated ___________, 1995, as
        amended from time to time, between the Company and Indemnitee) a
        "Change of Control" shall have occurred, by Independent Counsel
        (as hereinafter defined) (unless Indemnitee shall request that
        such determination be made by the Board of Directors, in which
        case the determination shall be made in the manner provided below
        in clause (ii) (A) as so requested by the Indemnitee, if
        applicable) in a written opinion, a copy of which shall be
        delivered to the Indemnitee; (ii) if a Change of Control shall
        not have occurred, (A) by the Board of Directors by a majority
        vote of a quorum of the Board consisting of Disinterested
        Directors (as hereinafter defined); or (B) if a quorum of the

                                      - 3 -




        Board of Directors consisting of Disinterested Directors is not
        obtainable or, even if obtainable, if such quorum of
        Disinterested Directors so directs, by Independent Counsel in a
        written opinion, a copy of which shall be delivered to the
        Indemnitee; or as provided in Section 8(a); and, if it is so
        determined that Indemnitee is entitled to indemnification,
        payment to Indemnitee shall be made within ten (10) days after
        such determination.  Indemnitee shall cooperate with the person,
        persons or entity making such determination with respect to
        Indemnitee's entitlement to indemnification, including providing
        to such person, persons or entity upon reasonable advance request
        any documentation or information which is not privileged or
        otherwise protected from disclosure and which is reasonably
        available to Indemnitee and reasonably necessary to such
        determination.  Any costs or expenses (including attorneys' fees
        and disbursements) incurred by Indemnitee in so cooperating with
        the person, persons or entity making such determination shall be
        borne by the Corporation (irrespective of the determination as to
        Indemnitee's entitlement to indemnification) and the Corporation
        hereby indemnities and agrees to hold Indemnitee harmless
        therefrom.  The person, persons or entity making the
        determination with respect to Indemnitee's entitlement to
        indemnification shall notify Indemnitee of such determination no
        later than two (2) days after the determination is made.

             (c)  In the event the determination of entitlement to
        indemnification is to be made by Independent Counsel pursuant to
        Section 7(b) hereof, the Independent Counsel shall be selected as
        provided in this Section 7(c).  The Independent Counsel shall be
        selected by the Board of Directors, and the Corporation shall
        give written notice to Indemnitee advising her of the identity of
        the Independent Counsel so selected.  Indemnitee may, within
        seven (7) days after such written notice of selection shall have
        been given, deliver to the Corporation a written objection to
        such selection.  Such objection may be asserted only on the
        ground that the Independent Counsel so selected does not meet the
        requirements of "Independent Counsel" as defined in Section 15
        hereof, and the objection shall set forth with particularity the
        factual basis of such assertion.  If such written objection is
        made, the Independent Counsel so selected may not serve as
        Independent Counsel unless and until a court of competent
        jurisdiction has determined that such objection is without merit.
        If, within 20 days after submission by Indemnitee of a written
        request for indemnification pursuant to Section 7(a) hereof,
        Independent Counsel shall not have been selected or if selected,
        shall have been objected to, Indemnitee may petition the Court of
        Chancery of the State of Delaware or other court of competent
        jurisdiction for resolution of any objection which shall have
        been made by the Corporation or Indemnitee to the other's
        selection of Independent Counsel and/or for the appointment as
        Independent Counsel of a person selected by the Court or by such
        other person as the Court shall designate, and the person with
        respect to whom an objection is so resolved or the person so
        appointed shall act as Independent Counsel under Section 7(b)

                                      - 4 -




        hereof.  The Corporation shall pay any and all reasonable fees
        and expenses of independent Counsel incurred by such Independent
        Counsel in connection with acting pursuant to Section 7(b)
        hereof, and the Corporation shall pay all reasonable fees and
        expenses incident to the procedures of this Section 7(c),
        regardless of the manner in which such independent Counsel was
        selected or appointed.  Upon the due commencement of any judicial
        proceeding or arbitration pursuant to Section 9(a) hereof,
        Independent Counsel shall be discharged and relieved of any
        further responsibility in such capacity (subject to the
        applicable standards of professional conduct then prevailing).

             (d)  If at the request of the Corporation Indemnitee is or
        was serving as a fiduciary with respect to an employee benefit
        plan, then for purposes of indemnification of Indemnitee under
        this Agreement (i) if Indemnitee acted in good faith and in a
        manner she reasonably believed to be in the interest of the
        participants and beneficiaries of said plan, Indemnitee shall be
        deemed to have acted in a manner not opposed to the best
        interests of the Corporation and (ii) "fines", for the purposes
        of the indemnification provided in Section 3 hereof shall be
        deemed to include any excise taxes imposed on Indemnitee with
        respect to such plan under applicable law.

             Section 8.  Presumptions and Effect of Certain Proceedings.

             (a)  If the person, persons or entity empowered or selected
        under Section 7 hereof to determine whether Indemnitee is
        entitled to indemnification shall not have made such
        determination within 90 days after receipt by the Corporation of
        the request therefor, the requisite determination of entitlement
        to indemnification shall be deemed to have been made and
        Indemnitee shall be entitled to such indemnification, absent (i)
        a misstatement by Indemnitee of a material fact, or an omission
        of a material fact necessary to make Indemnitee's statement not
        materially misleading, in connection with the request for
        indemnification, or (ii) a prohibition of such indemnification
        under applicable law; provided, however, that such 90-day period
        may be extended for a reasonable time, not to exceed an
        additional 30 days, if the person, persons or entity making the
        determination with respect to entitlement to indemnification in
        good faith, after notice to Indemnitee prior to the expiration of
        such 90-day period, requires such additional time for the
        obtaining or evaluating of documentation and/or information
        relating thereto.

             (c)  The termination of any Proceeding or of any claim,
        issue or matter therein by judgment, order, settlement or
        conviction, or upon a plea of nolo contendere or its equivalent,
        shall not (except as otherwise expressly provided in this
        Agreement) of itself adversely affect the right of Indemnitee to
        indemnification or create a presumption that Indemnitee did not
        act in good faith and in a manner which she reasonably believed
        to be in or not opposed to the best interests of the Corporation

                                      - 5 -




        or, with respect to any criminal Proceeding, that Indemnitee had
        reasonable cause to believe that her conduct was unlawful.

             Section 9.  Remedies of Indemnitee.

             (a)  Regardless of whether there has been a determination of
        whether or not the Indemnitee is entitled to indemnification
        hereunder, the Indemnitee may apply for indemnification to the
        court conducting any Proceeding to which the Indemnitee is a
        party or to any other court of competent jurisdiction.  On
        receipt of an application, the court, after giving any notice the
        court considers necessary, may order indemnification and
        advancement of Expenses if it determines the Indemnitee is
        entitled to indemnification and advancement of Expenses.
        Further, in the event that (i) a determination is made pursuant
        to Section 7 hereof that Indemnitee is not entitled to
        indemnification under this Agreement, (ii) advancement of
        Expenses is not timely made pursuant to Section 6 hereof, (iii)
        the determination of entitlement to indemnification is to be made
        by Independent Counsel pursuant to Section 7(b) hereof and such
        determination shall not have been made and delivered in a written
        opinion within the time period provided in Section 7, or (iv)
        payment of indemnification is not made within ten (10) days after
        a determination has been made that Indemnitee is entitled to
        indemnification or such determination is deemed to have been made
        pursuant to Section 7 or 8 hereof, Indemnitee shall be entitled
        to an adjudication in an appropriate court of the State of
        Delaware, or in any other court of competent jurisdiction, of her
        entitlement to such indemnification and advancement of Expenses.
        Alternatively, Indemnitee, at her option, may seek an award in
        arbitration to be conducted by a single arbitrator pursuant to
        the rules of the American Arbitration Association.  The
        Corporation shall not oppose Indemnitee's right to seek any such
        adjudication or award in arbitration.

             (b)  In the event that a determination shall have been made
        pursuant to Section 7 hereof that Indemnitee is not entitled to
        indemnification, any judicial proceeding or arbitration commenced
        pursuant to this Section 9 shall be conducted in all respects as
        a de novo trial, or arbitration, on the merits and Indemnitee
        shall not be prejudiced by reason of that adverse determination.

             (c)  If a determination shall have been made or deemed to
        have been made pursuant to Section 7 or 8 hereof that Indemnitee
        is entitled to indemnification, the Corporation shall be bound by
        such determination in any judicial proceeding or arbitration
        commenced pursuant to this Section 9, absent (i) a misstatement
        by Indemnitee of a material fact, or an omission of a material
        fact necessary to make Indemnitee's statement not materially
        misleading, in connection with the request for indemnification,
        or (ii) a prohibition of such indemnification under applicable
        law.



                                      - 6 -




             (d)  Subject to any undertakings made in any filing with the
        Securities and Exchange Commission approved by the Board and the
        provisions of applicable law, the Corporation shall be precluded
        from asserting in any judicial proceeding or arbitration
        commenced pursuant to this Section 9 that the procedures and
        presumptions of this Agreement are not valid, binding and
        enforceable and shall stipulate in any such court or before any
        such arbitrator that the Corporation is bound by all the
        provisions of this Agreement.

             (e)  In the event that Indemnitee, pursuant to this Section
        9, seeks a judicial adjudication of or an award in arbitration to
        enforce her rights under, or to recover damages for breach of,
        this Agreement, Indemnitee shall be entitled to recover from the
        Corporation, and shall be indemnified by the Corporation against,
        any and all expenses (of the types described in the definition of
        Expenses in Section 15 of this Agreement) actually and reasonably
        incurred by her in such judicial adjudication or arbitration, but
        only if she prevails therein.  If it shall be determined in said
        judicial adjudication or arbitration that Indemnitee is entitled
        to receive part but not all of the indemnification or advancement
        of Expenses sought, the expenses incurred by Indemnitee in
        connection with such judicial adjudication or arbitration shall
        be appropriately prorated.

             Section 10.  Non-Exclusivity: Survival of Rights; Insurance.

             (a)  The rights of indemnification and to receive
        advancement of Expenses as provided by this Agreement shall not
        be deemed exclusive of any other rights to which Indemnitee may
        at any time be entitled under applicable law, the Certificate of
        Incorporation, the By-Laws, any other agreement, a vote of
        stockholders or a resolution of directors, or otherwise.  To the
        extent that any amendment to the Corporation's Certificate of
        Incorporation or By-Laws permits the Corporation to provide or
        provides broader indemnification or advancement rights than
        provided herein, the Corporation agrees, upon written request of
        the Indemnitee, promptly to execute and deliver to Indemnitee an
        amendment to this Agreement which provides such broader
        indemnification or advancement rights, as the case may be, to
        Indemnitee, which amendment shall be in form and substance
        reasonably satisfactory to Indemnitee and her counsel and all
        expenses of preparation and review of any such amendment shall be
        the responsibility of the Corporation.  Failure of Indemnitee to
        request such an amendment shall neither create any presumption
        that Indemnitee is not entitled to the rights provided by the
        Company's Certificate of Incorporation or By-Laws nor limit
        Indemnitee's rights under the Company's Certificate of
        Incorporation or By-Laws.  Notwithstanding any amendment,
        alteration or repeal of any provision of this Agreement that
        would diminish any of Indemnitee's rights hereunder, Indemnitee
        shall, unless otherwise prohibited by law, have the rights of
        indemnification and to receive advancement of Expenses as
        provided by this Agreement in respect of any action taken or

                                      - 7 -




        omitted by Indemnitee in her Corporate status prior to or during
        the time this Agreement was in effect and in respect of any claim
        asserted in respect thereof.  The provisions of this Agreement
        shall continue as to an Indemnitee whose Corporate Status has
        ceased and shall inure to the benefit of her heirs, executors,
        administrators, and personal representatives.

             (b)  To the extent that the Corporation maintains an
        insurance policy or policies providing liability insurance for
        directors or officers of the Corporation or of any other
        corporation, partnership, joint venture, trust, employee benefit
        plan or other enterprise which such person serves at the request
        of the Corporation, Indemnitee shall be covered by such policy or
        policies in accordance with its or their terms to the maximum
        extent of the coverage available for any such director or officer
        under such policy or policies.

             (c)  The Corporation shall not be liable under this
        Agreement to make any payment of amounts otherwise indemnifiable
        hereunder if and to the extent that Indemnitee has otherwise
        actually received such payment under any insurance policy,
        contract, agreement or otherwise.

             (d)  To the extent that any provisions of this Agreement and
        any provision of the Corporation's By-Laws or Certificate of
        Incorporation providing for indemnification of Indemnitee are
        inconsistent as to the scope of such indemnification (except the
        procedures for indemnification), then to the extent not
        prohibited by applicable law, the provision providing for the
        greater scope shall control.  If any provision of this Agreement
        and any provision of the Corporation's By-Laws or Certificate of
        Incorporation are inconsistent as to the procedure to be followed
        for indemnification of Indemnitee, the provisions set forth
        herein shall govern, unless Indemnitee shall elect to have the
        procedures set forth in the By-Laws or Certificate of
        Incorporation apply or unless prohibited by law.

             Section 11.  Severability.  If any provision or provisions
        of this Agreement shall be held to be invalid, illegal or
        unenforceable for any reason whatsoever: (a) the validity,
        legality and enforceability of the remaining provisions of this
        Agreement (including without limitation, each portion of any
        Section of this Agreement containing any such provision held to
        be invalid, illegal or unenforceable, that is not itself invalid,
        illegal or unenforceable) shall not in any way be affected or
        impaired thereby; and (b) to the fullest extent possible, the
        provisions of this Agreement (including, without limitation, each
        portion of any Section of this Agreement containing any such
        provision held to be invalid, illegal or unenforceable, that is
        not itself invalid, illegal or unenforceable) shall be construed
        so as to give effect to the intent manifested by the provision
        held invalid, illegal or unenforceable.



                                      - 8 -




             Section 12.  Certain Persons Not Entitled to Indemnification
        or Advancement of Expenses.  Except as specifically authorized by
        Section 9 hereof with respect to a judicial proceeding or
        arbitration to enforce rights under this Agreement, neither the
        Indemnitee nor any other person shall be entitled to
        indemnification or advancement of Expenses under this Agreement
        with respect to any Proceeding, or any claim therein, brought or
        made by her against the Corporation, unless the Board of
        Directors, by majority vote of a quorum of the Board consisting
        of Disinterested Directors, specifically authorizes such
        indemnification or advancement of Expenses.

             Section 13.  Contribution.  If the indemnification provided
        for in this Agreement is due in accordance with its terms but is
        either held by a court of competent jurisdiction to be
        unavailable or is insufficient to hold harmless the Indemnitee,
        then the Corporation shall contribute to the amount paid or
        payable by the Indemnitee as a result of the Expenses, judgments,
        penalties, fines and amounts paid in settlement referred to
        herein in such proportion as is appropriate to reflect the
        relative fault of the Corporation and the Indemnitee in
        connection with the action or omissions which resulted in
        Expenses, judgments, penalties, fines and amounts paid in
        settlement as well as any other relevant equitable
        considerations.  The amount paid by the Indemnitee as a result of
        the Expenses, judgments, penalties, fines and amounts paid in
        settlement referred to in the first sentence of this Section 13
        shall be deemed to include any legal or other Expenses reasonably
        incurred by the Indemnitee in connection with investigating or
        defending any action or claim which is the subject of this
        Section 13.

             Section 14.  Successors; Extraordinary Transactions.

             (a)  This Agreement shall be binding upon the Corporation
        and its successors and assigns.

             (b)  The Corporation covenants and agrees that, in the event
        of (i) any merger, consolidation or reorganization in which the
        corporation is not the surviving entity, (ii) any transfer of all
        or substantially all the assets of the Company, (iii) any Change
        in control (each such event is referred to in the Agreement as an
        "Extraordinary Transaction"), the Corporation shall retain its
        obligations under this Agreement and cause the obligations of the
        Corporation under this Agreement to be expressly assumed by the
        survivor, purchaser or successor, as the case may be, in such
        Extraordinary Transaction and shall use its best efforts to cause
        the survivor, purchaser or successor, as the case may be, to (i)
        obtain and/or maintain insurance in favor of the Indemnitee from
        a reputable insurance carrier, which insurance shall provide at
        least the same coverage terms and conditions as provided to the
        Indemnitee immediately prior to such Extraordinary Transaction
        (unless and to the extent such insurance becomes unavailable or
        the premiums therefor become unreasonably expensive) for a period

                                      - 9 -




        of not less than five (5) years from the date of such
        Extraordinary Transaction against any liability to which the
        indemnification provided in this Agreement relates, or (ii)
        otherwise adequately provide for the satisfaction of the
        Corporation's obligations under this Agreement, in a manner
        acceptable to the Indemnitee.

             (c)  In the event of a potential Change in Control, the
        Corporation may create a trust for the benefit of the Indemnitee
        (either alone or together with one or more other indemnitees) and
        from time to time fund such trust in such amounts as the
        Corporation's Board of Directors may determine to satisfy
        Expenses reasonably anticipated to be incurred in connection with
        investigating, preparing for and defending any Proceeding, and
        all judgments, fines, penalties and settlement amounts of all
        Proceedings from time to time paid or claimed, reasonably
        anticipated or proposed to be paid.  The terms of any trust
        established pursuant hereto shall provide that upon a Change in
        Control (i) the trust shall not be revoked or the principal
        thereof invaded, without the written consent of the Indemnitee,
        (ii) the trustee shall advance, within two business days of a
        request by the Indemnitee all Expenses to the Indemnitee (and the
        Indemnitee hereby agrees to reimburse the trust under the
        circumstances under which the Indemnitee would be required to
        reimburse the Corporation under this Agreement), (iii) the
        trustee shall promptly pay to the Indemnitee all amounts for
        which the Indemnitee shall be entitled to indemnification
        pursuant to this Agreement or otherwise, and (iv) all unexpended
        funds in such trust shall revert to the Corporation upon a final
        determination by a court of competent jurisdiction that the
        Indemnitee has been fully indemnified under the terms of this
        Agreement.  The trustee shall be a person or entity satisfactory
        to the Indemnitee.  Nothing in this Section 14 shall relieve the
        Corporation of any of its obligations under this Agreement.

             Section 15.  Definitions.  For purposes of this Agreement:

             (a)  "Corporate Status" describes the status of a person who
        is or was or, to the maximum extent indemnification of such

        officer, employee or agent of the Corporation or of any other
        corporation, partnership, joint venture, trust, employee benefit
        plan or other enterprise which such person is or was serving at
        the request of the Corporation.

             (b)  "Disinterested Director" means a director of the

             (c)  "Expenses" shall include all reasonable attorneys'
        fees, retainers, court costs, transcript costs, fees of experts,
        witness fees, travel expenses, duplicating costs, printing and
        binding costs, telephone charges, postage, delivery service fees,
        and all other disbursements or expenditures of the types

                                      - 10 -




        customarily incurred in connection with prosecuting, defending,
        participating in, preparing to prosecute or defend or participate
        in, or investigating a Proceeding.

             (d)  "Independent Counsel" means a law firm, or a member of
        a law firm, that is experienced in matters of corporate law and
        neither presently is, nor in the past five years has been,
        retained to represent: (i) the Corporation or Indemnitee in any
        matter material to either such party, or (ii) any other party to
        the Proceeding giving rise to a claim for indemnification
        hereunder.  Notwithstanding the foregoing, the term "Independent
        Counsel" shall not include any person who, under the applicable
        standards of professional conduct then prevailing, would have a
        conflict of interest in representing either the Corporation or
        Indemnitee in an action to determine Indemnitee's rights under
        this Agreement.

             (e)  "Proceeding" includes any action, suit, arbitration,
        alternate dispute resolution mechanism, investigation,

        modification or amendment of this Agreement shall be binding
        unless executed in writing by both of the parties hereto.  No
        waiver of any of the provisions of this Agreement shall be deemed
        or shall constitute a waiver of any other provisions hereof
        (whether or not similar) nor shall such waiver constitute a
        continuing waiver.

             Section 17.  Notices.  All notices, requests, demands and
        other communications hereunder shall be in writing and shall be
        deemed to have been duly given if (i) delivered by hand and

                               EMPLOYMENT AGREEMENT

        approval shall not be unreasonably withheld.

             (e)  Bonus.  Executive shall be eligible to receive an
        annual bonus based upon achievement of corporate and individual

        to Executive's base salary to Executive's beneficiary designated
        in writing to CBC prior to his death (or to his estate if he
        fails to make such designation) for a period of six (6) months

                                      - 2 -




        after the date of Executive's death, at the salary rate in effect
        on the date of his death, said payments to be made on the same
        periodic dates as base salary payments would have been made to
        Executive had he not died.

             (b)  Termination by CBC for Cause.  Executive's employment
        hereunder may be terminated by CBC for cause, without further
        liability on the part of CBC, effective immediately by notice to
        Executive stating the nature of such cause.  The following shall
        constitute "cause" for such termination.

                  (i)  Deliberate dishonesty of Executive with respect to
             CBC or any subsidiary or affiliate thereof; or

                 (ii)  Conviction of Executive of a crime involving moral
             turpitude; or

                (iii)  The material failure by Executive to perform
             Executive's duties hereunder (other than any such failure
             resulting from the incapacity of Executive due to physical
             or mental illness) which failure continues for thirty (30)
             days after notice to Executive setting forth in reasonable
             detail the manner in which Executive has not performed
             Executive's duties; or

                 (iv)  Unlawful conduct pertaining to CBC or any of its
             affiliates or shareholders or involving a criminal act;
             material and conscious falsification or unauthorized
             disclosure of important records or reports; embezzlement or
             unauthorized conversion of property; violation of conflict
             of interest or vendor relations policies; or willful
             disclosure of significant trade secrets or other information
             likely to be used to the detriment of CBC.

             (c)  Termination by Executive for Cause.  Executive may
        terminate his employment hereunder without liability effective
        after thirty (30) days notice by Executive to CBC in the event of
        the material breach by CBC of this Agreement if such breach shall
        continue for more than thirty (30) days after notice to CBC
        setting forth in reasonable detail the nature of such breach.

             (d)  Termination by CBC Without Cause.  Executive's
        employment may be terminated without cause by CBC by thirty (30)
        days written notice to Executive.

             (e)  Certain Termination Benefits.  In the event of
        termination pursuant to Paragraphs 5(c) or 5(d), Executive shall
        be entitled to the following:

                  (i)  Base Salary.  For the period after the date of
             termination until the Expiration Date, CBC shall continue to
             pay Executive base salary at the rate in effect on the date
             of termination.


                                      - 3 -




                 (ii)  Regular Benefits.

                       (A)  For the period subsequent to the date of
                  termination until the Expiration Date, Executive shall
                  continue to receive at CBC's expense all benefits
                  described in Paragraph 4(b) existing on the date of
                  termination (except for any cash bonus plans which
                  shall be pro-rated through the date of termination),
                  provided that CBC's obligation to continue such
                  benefits shall cease on a benefit by benefit basis on
                  that date, if any, on which Executive is employed on a
                  full-time basis and Executive receives in connection
                  with such employment benefits which are substantially
                  equivalent to CBC's benefits.

                       (B)  For purpose of application of CBC's benefits,
                  Executive shall be treated, to the extent that
                  applicable law pertaining to the particular CBC benefit
                  plan permits CBC to do so, as if he had remained in the
                  employ of CBC, with a total annual salary at the rate
                  in effect on the date of termination and service or
                  similar credits, if any, will continue to accrue during
                  such period as if Executive had remained in the employ
                  of CBC.

                       (C)  If in spite of the provisions of this clause
                  (ii), benefits or service credits under any benefit
                  plan shall not be payable or provided under any such
                  plan to Executive, or to Executive's dependents,
                  beneficiaries or estate, because Executive is no longer
                  deemed to be an employee of CBC, CBC itself shall pay
                  or provide payment of such benefits and service credits
                  for such benefits to Executive or to Executive's
                  dependents, beneficiaries or estate.

                       (D)  To the extent that applicable law does not
                  permit any CBC benefit referred to above to be
                  provided, paid, or funded through the applicable CBC
                  benefit plan, then CBC shall not be required to provide
                  such benefit through such plan and shall only be
                  required to provide in the case of a benefit the tax
                  treatment of which is enhanced by such plan an amount
                  equal to what would have been CBC's initial
                  contribution to such plan and not the equivalent
                  benefit.

                (iii)  Set-off.  CBC shall be entitled to set off against
             any cash compensation to be provided to Executive under
             Paragraph 5(e) above 50 percent of the amount of any cash
             compensation received by Executive from other employment
             during the period in which Executive received cash
             compensation under Paragraph 5(e).  Executive shall inform
             CBC of any such amounts of cash compensation and shall
             refund to CBC any amount which CBC has paid which exceeds

                                      - 4 -




             the amounts due from CBC after application of the set-off
             provided for in this paragraph.  Notwithstanding the
             foregoing and any other provision of this Agreement,
             Executive shall be under no obligation to seek or accept any
             employment after termination of employment with CBC for any
             reason.

             6.   Disability.

             (a)  If, due to physical or mental illness, Executive shall
        be disabled so as to be unable to perform substantially all of
        his duties and responsibilities hereunder, CBC may designate
        another executive to act in his place during the period of such
        disability.  Notwithstanding any such designation, Executive
        shall continue to receive his full salary and benefits under
        Paragraph 4 of this Agreement, unless his employment is
        terminated as provided in this Paragraph 6.

             (b)  If Executive shall become totally and permanently
        disabled, then CBC may terminate Executive's employment hereunder
        and shall continue to pay to Executive his full salary and
        provide him with the benefits he was receiving immediately prior
        to such termination for six months, provided that such salary
        shall be reduced by the amount of any disability insurance
        proceeds actually paid to Executive or for his benefit with
        respect to such period of time under any disability policy
        provided by CBC for Executive.

             (c)  The determination that by virtue of total and permanent
        disability Executive is unable to perform his duties hereunder
        shall be made by a physician chosen by CBC and reasonably
        satisfactory to Executive (or Executive's legal representative)
        and such determination shall be conclusive.  The cost of such
        examination shall be borne by CBC.  Executive shall be
        conclusively presumed to be totally and permanently disabled if
        for reasons involving physical or mental illness or injury
        Executive fails to perform his duties hereunder for a period of
        one hundred twenty (120) consecutive calendar days or for any
        periods aggregating one hundred twenty (120) days or more in any
        six (6) consecutive month period.  The date of termination of
        Executive's employment hereunder in the event of total and
        permanent disability shall be the earlier of such physicians's
        examination pursuant to which such determination is made or the
        first business day after which either such 120-day period or such
        six-month period has expired.

             7.   Non-competition, Confidential Information, and Non-
                  Solicitation.

             (a)  Non-competition.  Executive agrees that he will not at
        any time during the term of this Agreement and for a period of
        two (2) years following the termination of this Agreement for any
        reason, directly or indirectly, as a partner, officer, director,
        consultant, employee, stockholder or otherwise, engage in any

                                      - 5 -




        employment, pursuit or association in which he shall have
        substantial responsibility with respect to products and/or
        services which are in direct competition with products and/or
        services of CBC, provided however, in any event the holding by
        Executive of any investment in any security shall not be deemed
        to be a violation of this Paragraph 7 if such investment does not
        constitute more than 5% of the outstanding issue of such
        security.

             (b)  Confidential Information.  Executive will not disclose
        to any other person (except as required by applicable law or in
        connection with the performance of his duties and
        responsibilities hereunder), or use for his own benefit or gain,
        any confidential information of CBC obtained by him incident to
        his employment with CBC.  The term "confidential information"
        includes, without limitation, financial information, business
        plans, prospects and opportunities (such as lending
        relationships, financial product developments, possible
        acquisitions or dispositions of businesses or facilities),
        products, plans, intellectual property, analyses, projects,
        processes, marketing, research or development activities, and all
        technical or scientific information or know-how of CBC which have
        been discussed or considered by CBC but does not include any
        information which has become part of the public domain by means
        other than Executive's non-observance of his obligations
        hereunder.

             (c)  Non-solicitation.  Executive agrees that he will not at
        any time during the term of this Agreement and for a period of
        three (3) years following the termination of this Agreement for
        any reason, directly or indirectly, solicit or recruit any
        employee of CBC to serve as an employee of, consultant to, or
        partner of Executive or any entity.

             (d)  Relief; Interpretation.  Executive agrees that CBC
        shall be entitled to injunctive relief for any breach by him of
        the covenants contained in Paragraphs 7(a), (b), or (c).  In the
        event that any provision of this Paragraph 7 shall be determined
        by any court of competent jurisdiction to be unenforceable by
        reason of its being extended over too great a period of time, too
        large a geographic area, or too great a range of activities, it
        shall be interpreted to extend only over the maximum period of
        time, geographic areas, or range of activities as to which it may
        be enforceable.  For purposes of this Paragraph 7, the term "CBC"
        shall mean CBC and any of its subsidiaries.

             (e)  Survival.  Executive's obligations under this
        Paragraph 7 shall survive termination of this Agreement.

             8.   Conflicting Agreements.  Executive hereby represents
        and warrants that the execution of this Agreement and the
        performance of his obligations hereunder will not breach or be in
        conflict with any other agreement to which he is a party or is
        bound, and that he is not now subject to any covenants against

                                      - 6 -




        competition or similar covenants which would affect the
        performance of his obligations hereunder.

             9.   Withholding.  All payments made by CBC under this
        Agreement shall be net of any tax or other amounts required to be
        withheld by CBC under applicable law.

             10.  Arbitration of Disputes.  Any controversy or claim
        arising out of or relating to this Agreement or the breach
        thereof shall be settled by arbitration in accordance with the
        laws of the Commonwealth of Massachusetts by three arbitrators.
        The party initiating arbitration shall nominate one arbitrator in
        the request for arbitration and the other party shall nominate a
        second in the answer thereto within thirty (30) days of receipt
        of the request.  The two arbitrators so named will then jointly
        appoint the third arbitrator.  If the answering party fails to
        nominate its arbitrator within the thirty (30) day period, or if
        the arbitrators named by the parties fail to agree on the third
        arbitrator within sixty (60) days, then such arbitrator shall be
        appointed by the American Arbitration Association in the City of
        Boston.  Such arbitration shall be conducted in the City of
        Worcester, Massachusetts in accordance with the rules of the
        American Arbitration Association, except with respect to the
        selection of arbitrators which shall be provided in this
        Paragraph 10.  Judgment upon the award entered by the arbitrators
        may be entered in any court having jurisdiction thereof.

             11.  Assignment, Successors and Assigns, etc.  Neither the
        employer nor Executive may make any assignment of this Agreement
        or any interest herein, by operation of law or otherwise, without
        the prior written consent of the other party; provided, however,
        that CBC may assign its rights under this Agreement without the
        consent of Executive in the event CBC shall hereafter consolidate
        with or merge into any other person, or transfer all or
        substantially all of its properties or assets to any other
        person.  In the event of the Executive's death prior to the
        completion by CBC of all payments due him under this Agreement,
        CBC shall continue such payments to the Executive's beneficiary
        designated in writing to CBC prior to his death (or to his
        estate, if he fails to make such designation).  This Agreement
        shall inure to the benefit of and be binding upon CBC and the
        Executive, their respective successors, executors,
        administrators, heirs and permitted assigns.

             12.  Enforceability.  If any portion or provision of this
        Agreement shall to any extent be declared illegal or
        unenforceable by a court of competent jurisdiction, then the
        remainder of this Agreement, or the application of such portion
        or provision in circumstances other than those as to which it is
        so declared illegal or unenforceable, shall not be affected
        thereby, and each portion and provision of this Agreement shall
        be valid and enforceable to the fullest extent permitted by law.



                                      - 7 -




             13.  Waiver.  No waiver of any provision hereof shall be
        effective unless made in writing and signed by the waiving party.
        The failure of any party to require the performance of any term
        or obligation of this Agreement, or the waiver by any party of
        any breach of this Agreement, shall not prevent any subsequent
        enforcement of such term or obligation or be deemed a waiver of
        any subsequent breach.

             14.  Notices.  All notices and other communications required
        or permitted hereunder shall be in writing and shall be
        delivered, mailed by first-class mail, postage prepaid, or sent
        by telex or facsimile with a mailed confirmation copy, addressed:

        facsimile or telex on the date of delivery or sending provided
        such day is a business day and in the case of notices or
        communications which have been mailed on the second business day
        after the date mailed.

             15.  Amendment.  This Agreement may be amended or modified
        only by a written instrument signed by Executive and by a duly
        authorized representative of CBC.

             16.  Governing Law.  This is a Massachusetts contract and
        shall be construed under and be governed in all respects by the
        laws of the Commonwealth of Massachusetts without reference to
        its conflict of laws provisions.

             17.  Entire Agreement.  Except for the Invention and Non-

        Agreement constitutes the entire understanding between the
        parties with respect to the subject matter hereunder and
        supersedes and replaces all prior agreements, including the
        employment agreement between Executive and CBC dated April 15,
        1994, understandings, writings, and discussions between the
        parties.

                                      - 8 -




             IN WITNESS WHEREOF, this Agreement has been executed as a
        sealed instrument by CBC, by its duly authorized officers, and by
        the Executive, as of the date first above written.

        sometimes referred to as the "Expiration Date."

             4.   Compensation and Benefits.  For all services rendered
        by Executive during her employment hereunder, CBC shall
        compensate Executive as follows:

             (a)  Salary.  CBC shall pay Executive a base salary of
        $130,000 per year, subject to increase from time to time in
        accordance with the usual practice of CBC with respect to review
        of compensation of its senior executives.  Executive's salary
        shall be payable in periodic installments in accordance with
        CBC's usual practice for its senior executives.

             (b)  Regular Benefits.  Executive shall be entitled to
        participate in any and all employee benefit plans, medical
        insurance plans, life insurance plans, disability income plans,
        retirement plans, bonus incentive plans and other benefit plans
        from time to time in effect for senior executives of CBC.  Such
        participation shall be subject to: (i) the terms of the
        applicable plan documents; (ii) generally applicable policies of
        CBC; and (iii) the discretion of the Board or any administrative
        or other committee provided for in or contemplated by such plan.

             (c)  Business Expenses.  CBC shall reimburse Executive for
        all reasonable travel and other business expenses incurred by her
        in the performance of her duties and responsibilities, subject to
        such reasonable requirements with respect to substantiation and
        documentation as may be specified by CBC.

             (d)  Vacation.  Executive shall be entitled to paid vacation
        in accordance with the policies of CBC (but in no event less than
        four weeks per year), to be taken at such times and intervals as
        shall be determined by Executive with the approval of CBC, which
        approval shall not be unreasonably withheld.

             (e)  Bonus.  Executive shall be eligible to receive an
        annual bonus based upon achievement of corporate and individual
        objectives; the award of any bonus shall lie solely in the
        discretion of the Board of Directors.

             5.   Termination and Termination Benefits.  Notwithstanding
        the provisions of Paragraph 3, Executive's employment hereunder
        shall terminate under the following circumstances:

             (a)  Death.  In the event of Executive's death during her
        employment hereunder, CBC shall continue to pay an amount equal
        to Executive's base salary to Executive's beneficiary designated
        in writing to CBC prior to her death (or to her estate if she
        fails to make such designation) for a period of six (6) months

                                      - 2 -




        after the date of Executive's death, at the salary rate in effect
        on the date of her death, said payments to be made on the same
        periodic dates as base salary payments would have been made to
        Executive had she not died.

             (b)  Termination by CBC for Cause.  Executive's employment
        hereunder may be terminated by CBC for cause, without further
        liability on the part of CBC, effective immediately by notice to
        Executive stating the nature of such cause.  The following shall
        constitute "cause" for such termination.

                  (i)  Deliberate dishonesty of Executive with respect to
             CBC or any subsidiary or affiliate thereof; or

                 (ii)  Conviction of Executive of a crime involving moral
             turpitude; or

                (iii)  The material failure by Executive to perform
             Executive's duties hereunder (other than any such failure
             resulting from the incapacity of Executive due to physical
             or mental illness) which failure continues for thirty (30)
             days after notice to Executive setting forth in reasonable
             detail the manner in which Executive has not performed
             Executive's duties; or

                 (iv)  Unlawful conduct pertaining to CBC or any of its
             affiliates or shareholders or involving a criminal act;
             material and conscious falsification or unauthorized
             disclosure of important records or reports; embezzlement or
             unauthorized conversion of property; violation of conflict
             of interest or vendor relations policies; or willful
             disclosure of significant trade secrets or other information
             likely to be used to the detriment of CBC.

             (c)  Termination by Executive for Cause.  Executive may
        terminate her employment hereunder without liability effective
        after thirty (30) days notice by Executive to CBC in the event of
        the material breach by CBC of this Agreement if such breach shall
        continue for more than thirty (30) days after notice to CBC
        setting forth in reasonable detail the nature of such breach.

             (d)  Termination by CBC Without Cause.  Executive's
        employment may be terminated without cause by CBC by thirty (30)
        days written notice to Executive.

             (e)  Certain Termination Benefits.  In the event of
        termination pursuant to Paragraphs 5(c) or 5(d), Executive shall
        be entitled to the following:

                  (i)  Base Salary.  For the period after the date of
             termination until the Expiration Date, CBC shall continue to
             pay Executive base salary at the rate in effect on the date
             of termination.


                                      - 3 -




                 (ii)  Regular Benefits.

                       (A)  For the period subsequent to the date of
                  termination until the Expiration Date, Executive shall
                  continue to receive at CBC's expense all benefits
                  described in Paragraph 4(b) existing on the date of
                  termination (except for any cash bonus plans which
                  shall be pro-rated through the date of termination),
                  provided that CBC's obligation to continue such
                  benefits shall cease on a benefit by benefit basis on
                  that date, if any, on which Executive is employed on a
                  full-time basis and Executive receives in connection
                  with such employment benefits which are substantially
                  equivalent to CBC's benefits.

                       (B)  For purpose of application of CBC's benefits,
                  Executive shall be treated, to the extent that
                  applicable law pertaining to the particular CBC benefit
                  plan permits CBC to do so, as if she had remained in
                  the employ of CBC, with a total annual salary at the
                  rate in effect on the date of termination and service
                  or similar credits, if any, will continue to accrue
                  during such period as if Executive had remained in the
                  employ of CBC.

                       (C)  If in spite of the provisions of this clause
                  (ii), benefits or service credits under any benefit
                  plan shall not be payable or provided under any such
                  plan to Executive, or to Executive's dependents,
                  beneficiaries or estate, because Executive is no longer
                  deemed to be an employee of CBC, CBC itself shall pay
                  or provide payment of such benefits and service credits
                  for such benefits to Executive or to Executive's
                  dependents, beneficiaries or estate.

                       (D)  To the extent that applicable law does not
                  permit any CBC benefit referred to above to be
                  provided, paid, or funded through the applicable CBC
                  benefit plan, then CBC shall not be required to provide
                  such benefit through such plan and shall only be
                  required to provide in the case of a benefit the tax
                  treatment of which is enhanced by such plan an amount
                  equal to what would have been CBC's initial
                  contribution to such plan and not the equivalent
                  benefit.

                (iii)  Set-off.  CBC shall be entitled to set off against
             any cash compensation to be provided to Executive under
             Paragraph 5(e) above 50 percent of the amount of any cash
             compensation received by Executive from other employment
             during the period in which Executive received cash
             compensation under Paragraph 5(e).  Executive shall inform
             CBC of any such amounts of cash compensation and shall
             refund to CBC any amount which CBC has paid which exceeds

                                      - 4 -




             the amounts due from CBC after application of the set-off
             provided for in this paragraph.  Notwithstanding the
             foregoing and any other provision of this Agreement,
             Executive shall be under no obligation to seek or accept any
             employment after termination of employment with CBC for any
             reason.

             6.   Disability.

             (a)  If, due to physical or mental illness, Executive shall
        be disabled so as to be unable to perform substantially all of
        her duties and responsibilities hereunder, CBC may designate
        another executive to act in her place during the period of such
        disability.  Notwithstanding any such designation, Executive
        shall continue to receive her full salary and benefits under
        Paragraph 4 of this Agreement, unless her employment is
        terminated as provided in this Paragraph 6.

             (b)  If Executive shall become totally and permanently
        disabled, then CBC may terminate Executive's employment hereunder
        and shall continue to pay to Executive her full salary and
        provide her with the benefits she was receiving immediately prior
        to such termination for six months, provided that such salary
        shall be reduced by the amount of any disability insurance
        proceeds actually paid to Executive or for her benefit with
        respect to such period of time under any disability policy
        provided by CBC for Executive.

             (c)  The determination that by virtue of total and permanent
        disability Executive is unable to perform her duties hereunder
        shall be made by a physician chosen by CBC and reasonably
        satisfactory to Executive (or Executive's legal representative)
        and such determination shall be conclusive.  The cost of such
        examination shall be borne by CBC.  Executive shall be
        conclusively presumed to be totally and permanently disabled if
        for reasons involving physical or mental illness or injury
        Executive fails to perform her duties hereunder for a period of
        one hundred twenty (120) consecutive calendar days or for any
        periods aggregating one hundred twenty (120) days or more in any
        six (6) consecutive month period.  The date of termination of
        Executive's employment hereunder in the event of total and
        permanent disability shall be the earlier of such physicians's
        examination pursuant to which such determination is made or the
        first business day after which either such 120-day period or such
        six-month period has expired.

             7.   Non-competition, Confidential Information, and Non-
                  Solicitation.

             (a)  Non-competition.  Executive agrees that he will not at
        any time during the term of this Agreement and for a period of
        two (2) years following the termination of this Agreement for any
        reason, directly or indirectly, as a partner, officer, director,
        consultant, employee, stockholder or otherwise, engage in any

                                      - 5 -




        employment, pursuit or association in which he shall have
        substantial responsibility with respect to products and/or
        services which are in direct competition with products and/or
        services of CBC, provided however, in any event the holding by
        Executive of any investment in any security shall not be deemed
        to be a violation of this Paragraph 7 if such investment does not
        constitute more than 5% of the outstanding issue of such
        security.

             (b)  Confidential Information.  Executive will not disclose
        to any other person (except as required by applicable law or in
        connection with the performance of his duties and
        responsibilities hereunder), or use for his own benefit or gain,
        any confidential information of CBC obtained by him incident to
        his employment with CBC.  The term "confidential information"
        includes, without limitation, financial information, business
        plans, prospects and opportunities (such as lending
        relationships, financial product developments, possible
        acquisitions or dispositions of businesses or facilities),
        products, plans, intellectual property, analyses, projects,
        processes, marketing, research or development activities, and all
        technical or scientific information or know-how of CBC which have
        been discussed or considered by CBC but does not include any
        information which has become part of the public domain by means
        other than Executive's non-observance of his obligations
        hereunder.

             (c)  Non-solicitation.  Executive agrees that he will not at
        any time during the term of this Agreement and for a period of
        three (3) years following the termination of this Agreement for
        any reason, directly or indirectly, solicit or recruit any
        employee of CBC to serve as an employee of, consultant to, or
        partner of Executive or any entity.

             (d)  Relief; Interpretation.  Executive agrees that CBC
        shall be entitled to injunctive relief for any breach by him of
        the covenants contained in Paragraphs 7(a), (b), or (c).  In the
        event that any provision of this Paragraph 7 shall be determined
        by any court of competent jurisdiction to be unenforceable by
        reason of its being extended over too great a period of time, too
        large a geographic area, or too great a range of activities, it
        shall be interpreted to extend only over the maximum period of
        time, geographic areas, or range of activities as to which it may
        be enforceable.  For purposes of this Paragraph 7, the term "CBC"
        shall mean CBC and any of its subsidiaries.

             (e)  Survival.  Executive's obligations under this
        Paragraph 7 shall survive termination of this Agreement.

             8.   Conflicting Agreements.  Executive hereby represents
        and warrants that the execution of this Agreement and the
        performance of his obligations hereunder will not breach or be in
        conflict with any other agreement to which he is a party or is
        bound, and that he is not now subject to any covenants against

                                      - 6 -




        competition or similar covenants which would affect the
        performance of his obligations hereunder.

             9.   Withholding.  All payments made by CBC under this
        Agreement shall be net of any tax or other amounts required to be
        withheld by CBC under applicable law.

             10.  Arbitration of Disputes.  Any controversy or claim
        arising out of or relating to this Agreement or the breach
        thereof shall be settled by arbitration in accordance with the
        laws of the Commonwealth of Massachusetts by three arbitrators.
        The party initiating arbitration shall nominate one arbitrator in
        the request for arbitration and the other party shall nominate a
        second in the answer thereto within thirty (30) days of receipt
        of the request.  The two arbitrators so named will then jointly
        appoint the third arbitrator.  If the answering party fails to
        nominate its arbitrator within the thirty (30) day period, or if
        the arbitrators named by the parties fail to agree on the third
        arbitrator within sixty (60) days, then such arbitrator shall be
        appointed by the American Arbitration Association in the City of
        Boston.  Such arbitration shall be conducted in the City of
        Worcester, Massachusetts in accordance with the rules of the
        American Arbitration Association, except with respect to the
        selection of arbitrators which shall be provided in this
        Paragraph 10.  Judgment upon the award entered by the arbitrators
        may be entered in any court having jurisdiction thereof.

             11.  Assignment, Successors and Assigns, etc.  Neither the
        employer nor Executive may make any assignment of this Agreement
        or any interest herein, by operation of law or otherwise, without
        the prior written consent of the other party; provided, however,
        that CBC may assign its rights under this Agreement without the
        consent of Executive in the event CBC shall hereafter consolidate
        with or merge into any other person, or transfer all or
        substantially all of its properties or assets to any other
        person.  In the event of the Executive's death prior to the
        completion by CBC of all payments due him under this Agreement,
        CBC shall continue such payments to the Executive's beneficiary
        designated in writing to CBC prior to his death (or to his
        estate, if he fails to make such designation).  This Agreement
        shall inure to the benefit of and be binding upon CBC and the
        Executive, their respective successors, executors,
        administrators, heirs and permitted assigns.

             12.  Enforceability.  If any portion or provision of this
        Agreement shall to any extent be declared illegal or
        unenforceable by a court of competent jurisdiction, then the
        remainder of this Agreement, or the application of such portion
        or provision in circumstances other than those as to which it is
        so declared illegal or unenforceable, shall not be affected
        thereby, and each portion and provision of this Agreement shall
        be valid and enforceable to the fullest extent permitted by law.



                                      - 7 -




             13.  Waiver.  No waiver of any provision hereof shall be
        effective unless made in writing and signed by the waiving party.
        The failure of any party to require the performance of any term
        or obligation of this Agreement, or the waiver by any party of
        any breach of this Agreement, shall not prevent any subsequent
        enforcement of such term or obligation or be deemed a waiver of
        any subsequent breach.

             14.  Notices.  All notices and other communications required
        or permitted hereunder shall be in writing and shall be
        delivered, mailed by first-class mail, postage prepaid, or sent
        by telex or facsimile with a mailed confirmation copy, addressed:

        or such other addresses or facsimile numbers as shall be
        furnished in writing by either party and any such notice or
        communication shall be deemed to have been given in the case of
        notices or communications which have been delivered or sent by
        facsimile or telex on the date of delivery or sending provided
        such day is a business day and in the case of notices or
        communications which have been mailed on the second business day
        after the date mailed.

             15.  Amendment.  This Agreement may be amended or modified
        only by a written instrument signed by Executive and by a duly
        authorized representative of CBC.

             16.  Governing Law.  This is a Massachusetts contract and
        shall be construed under and be governed in all respects by the
        laws of the Commonwealth of Massachusetts without reference to
        its conflict of laws provisions.

             17.  Entire Agreement.  Except for the Invention and Non-
        Disclosure Agreement dated May 18, 1993, which shall remain in
        full force and effect in accordance with its terms, this
        Agreement constitutes the entire understanding between the
        parties with respect to the subject matter hereunder and
        supersedes and replaces all prior agreements, including the
        employment agreement between Executive and CBC dated July 7,
        1993, understandings, writings, and discussions between the
        parties.  Notwithstanding the foregoing, Executive shall be

                                      - 8 -




        entitled to an unsecured non-priority claim in the bankruptcy
        proceedings of CBC representing any and all claims of Executive
        against CBC for prior services or otherwise in the amount as set
        forth in the Statement of Claim executed between Executive and
        CBC contemporaneous herewith.

             IN WITNESS WHEREOF, this Agreement has been executed as a
        sealed instrument by CBC, by its duly authorized officers, and by
        the Executive, as of the date first above written.

             WHEREAS, CBC has filed a petition under Chapter 11 of the
        United States Bankruptcy Code (the "Code");

             WHEREAS, CBC and Executive are parties to an employment
        agreement dated as of July 7, 1993, which CBC and Executive have
        elected to terminate without liability or obligation to either
        party except as provided herein;

             WHEREAS, CBC desires to employ Executive for the period and
        upon the terms and conditions provided in this Agreement; and

             WHEREAS, Executive desires to serve in the employ of CBC on

        provided.

             2.   Position and Responsibilities; Principal Location.

             (a)  During the term of this Agreement, Executive will serve
        as Vice President of Medical Affairs, subject to election by the

             3.   Term of Employment.  The term of Executive's employment
        hereunder shall be for two years from the Commencement Date;




        provided, however, that thereafter the term shall be extended
        automatically to the date which is 180 days after either party
        shall deliver written notice to the other of such party's
        election not to extend the term of this Agreement.  The last day
        of such term, as may be extended from time to time, is herein
        sometimes referred to as the "Expiration Date."

             4.   Compensation and Benefits.  For all services rendered
        by Executive during his employment hereunder, CBC shall
        compensate Executive as follows:

             (a)  Salary.  CBC shall pay Executive a base salary of
        $150,000 per year, subject to increase from time to time in
        accordance with the usual practice of CBC with respect to review
        of compensation of its senior executives.  Executive's salary
        shall be payable in periodic installments in accordance with
        CBC's usual practice for its senior executives.

             (b)  Regular Benefits.  Executive shall be entitled to
        participate in any and all employee benefit plans, medical
        insurance plans, life insurance plans, disability income plans,
        retirement plans, bonus incentive plans and other benefit plans
        from time to time in effect for senior executives of CBC.  Such
        participation shall be subject to: (i) the terms of the
        applicable plan documents; (ii) generally applicable policies of
        CBC; and (iii) the discretion of the Board or any administrative
        or other committee provided for in or contemplated by such plan.

             (c)  Business Expenses.  CBC shall reimburse Executive for
        all reasonable travel and other business expenses incurred by him
        in the performance of his duties and responsibilities, subject to
        such reasonable requirements with respect to substantiation and
        documentation as may be specified by CBC.

             (d)  Vacation.  Executive shall be entitled to paid vacation
        in accordance with the policies of CBC (but in no event less than
        four weeks per year), to be taken at such times and intervals as
        shall be determined by Executive with the approval of CBC, which
        approval shall not be unreasonably withheld.

             (e)  Bonus.  Executive shall be eligible to receive an
        annual bonus based upon achievement of corporate and individual
        objectives; the award of any bonus shall lie solely in the
        discretion of the Board of Directors.

             5.   Termination and Termination Benefits.  Notwithstanding
        the provisions of Paragraph 3, Executive's employment hereunder
        shall terminate under the following circumstances:

             (a)  Death.  In the event of Executive's death during his
        employment hereunder, CBC shall continue to pay an amount equal
        to Executive's base salary to Executive's beneficiary designated
        in writing to CBC prior to his death (or to his estate if he
        fails to make such designation) for a period of six (6) months

                                      - 2 -




        after the date of Executive's death, at the salary rate in effect
        on the date of his death, said payments to be made on the same
        periodic dates as base salary payments would have been made to
        Executive had he not died.

             (b)  Termination by CBC for Cause.  Executive's employment
        hereunder may be terminated by CBC for cause, without further
        liability on the part of CBC, effective immediately by notice to
        Executive stating the nature of such cause.  The following shall
        constitute "cause" for such termination.

                  (i)  Deliberate dishonesty of Executive with respect to
             CBC or any subsidiary or affiliate thereof; or

                 (ii)  Conviction of Executive of a crime involving moral
             turpitude; or

                (iii)  The material failure by Executive to perform
             Executive's duties hereunder (other than any such failure
             resulting from the incapacity of Executive due to physical
             or mental illness) which failure continues for thirty (30)
             days after notice to Executive setting forth in reasonable
             detail the manner in which Executive has not performed
             Executive's duties; or

                 (iv)  Unlawful conduct pertaining to CBC or any of its
             affiliates or shareholders or involving a criminal act;
             material and conscious falsification or unauthorized
             disclosure of important records or reports; embezzlement or
             unauthorized conversion of property; violation of conflict
             of interest or vendor relations policies; or willful
             disclosure of significant trade secrets or other information
             likely to be used to the detriment of CBC.

             (c)  Termination by Executive for Cause.  Executive may
        terminate his employment hereunder without liability effective
        after thirty (30) days notice by Executive to CBC in the event of
        the material breach by CBC of this Agreement if such breach shall
        continue for more than thirty (30) days after notice to CBC
        setting forth in reasonable detail the nature of such breach.

             (d)  Termination by CBC Without Cause.  Executive's
        employment may be terminated without cause by CBC by thirty (30)
        days written notice to Executive.

             (e)  Certain Termination Benefits.  In the event of
        termination pursuant to Paragraphs 5(c) or 5(d), Executive shall
        be entitled to the following:

                  (i)  Base Salary.  For the period after the date of
             termination until the Expiration Date, CBC shall continue to
             pay Executive base salary at the rate in effect on the date
             of termination.


                                      - 3 -




                 (ii)  Regular Benefits.

                       (A)  For the period subsequent to the date of
                  termination until the Expiration Date, Executive shall
                  continue to receive at CBC's expense all benefits
                  described in Paragraph 4(b) existing on the date of
                  termination (except for any cash bonus plans which
                  shall be pro-rated through the date of termination),
                  provided that CBC's obligation to continue such
                  benefits shall cease on a benefit by benefit basis on
                  that date, if any, on which Executive is employed on a
                  full-time basis and Executive receives in connection
                  with such employment benefits which are substantially
                  equivalent to CBC's benefits.

                       (B)  For purpose of application of CBC's benefits,
                  Executive shall be treated, to the extent that
                  applicable law pertaining to the particular CBC benefit
                  plan permits CBC to do so, as if he had remained in the
                  employ of CBC, with a total annual salary at the rate
                  in effect on the date of termination and service or
                  similar credits, if any, will continue to accrue during
                  such period as if Executive had remained in the employ
                  of CBC.

                       (C)  If in spite of the provisions of this clause
                  (ii), benefits or service credits under any benefit
                  plan shall not be payable or provided under any such
                  plan to Executive, or to Executive's dependents,
                  beneficiaries or estate, because Executive is no longer
                  deemed to be an employee of CBC, CBC itself shall pay
                  or provide payment of such benefits and service credits
                  for such benefits to Executive or to Executive's
                  dependents, beneficiaries or estate.

                       (D)  To the extent that applicable law does not
                  permit any CBC benefit referred to above to be
                  provided, paid, or funded through the applicable CBC
                  benefit plan, then CBC shall not be required to provide
                  such benefit through such plan and shall only be
                  required to provide in the case of a benefit the tax
                  treatment of which is enhanced by such plan an amount
                  equal to what would have been CBC's initial
                  contribution to such plan and not the equivalent
                  benefit.

                (iii)  Set-off.  CBC shall be entitled to set off against
             any cash compensation to be provided to Executive under
             Paragraph 5(e) above 50 percent of the amount of any cash
             compensation received by Executive from other employment
             during the period in which Executive received cash
             compensation under Paragraph 5(e).  Executive shall inform
             CBC of any such amounts of cash compensation and shall
             refund to CBC any amount which CBC has paid which exceeds

                                      - 4 -




             the amounts due from CBC after application of the set-off
             provided for in this paragraph.  Notwithstanding the
             foregoing and any other provision of this Agreement,
             Executive shall be under no obligation to seek or accept any
             employment after termination of employment with CBC for any
             reason.

             6.   Disability.

             (a)  If, due to physical or mental illness, Executive shall
        be disabled so as to be unable to perform substantially all of
        his duties and responsibilities hereunder, CBC may designate
        another executive to act in his place during the period of such
        disability.  Notwithstanding any such designation, Executive
        shall continue to receive his full salary and benefits under
        Paragraph 4 of this Agreement, unless his employment is
        terminated as provided in this Paragraph 6.

             (b)  If Executive shall become totally and permanently
        disabled, then CBC may terminate Executive's employment hereunder
        and shall continue to pay to Executive his full salary and
        provide him with the benefits he was receiving immediately prior
        to such termination for six months, provided that such salary
        shall be reduced by the amount of any disability insurance
        proceeds actually paid to Executive or for his benefit with
        respect to such period of time under any disability policy
        provided by CBC for Executive.

             (c)  The determination that by virtue of total and permanent
        disability Executive is unable to perform his duties hereunder
        shall be made by a physician chosen by CBC and reasonably
        satisfactory to Executive (or Executive's legal representative)
        and such determination shall be conclusive.  The cost of such
        examination shall be borne by CBC.  Executive shall be
        conclusively presumed to be totally and permanently disabled if
        for reasons involving physical or mental illness or injury
        Executive fails to perform his duties hereunder for a period of
        one hundred twenty (120) consecutive calendar days or for any
        periods aggregating one hundred twenty (120) days or more in any
        six (6) consecutive month period.  The date of termination of
        Executive's employment hereunder in the event of total and
        permanent disability shall be the earlier of such physicians's
        examination pursuant to which such determination is made or the
        first business day after which either such 120-day period or such
        six-month period has expired.

             7.   Non-competition, Confidential Information, and Non-
                  Solicitation.

             (a)  Non-competition.  Executive agrees that he will not at
        any time during the term of this Agreement and for a period of
        two (2) years following the termination of this Agreement for any
        reason, directly or indirectly, as a partner, officer, director,
        consultant, employee, stockholder or otherwise, engage in any

                                      - 5 -




        employment, pursuit or association in which he shall have
        substantial responsibility with respect to products and/or
        services which are in direct competition with products and/or
        services of CBC, provided however, in any event the holding by
        Executive of any investment in any security shall not be deemed
        to be a violation of this Paragraph 7 if such investment does not
        constitute more than 5% of the outstanding issue of such
        security.

             (b)  Confidential Information.  Executive will not disclose
        to any other person (except as required by applicable law or in
        connection with the performance of his duties and
        responsibilities hereunder), or use for his own benefit or gain,
        any confidential information of CBC obtained by him incident to
        his employment with CBC.  The term "confidential information"
        includes, without limitation, financial information, business
        plans, prospects and opportunities (such as lending
        relationships, financial product developments, possible
        acquisitions or dispositions of businesses or facilities),
        products, plans, intellectual property, analyses, projects,
        processes, marketing, research or development activities, and all
        technical or scientific information or know-how of CBC which have
        been discussed or considered by CBC but does not include any
        information which has become part of the public domain by means
        other than Executive's non-observance of his obligations
        hereunder.

             (c)  Non-solicitation.  Executive agrees that he will not at
        any time during the term of this Agreement and for a period of
        three (3) years following the termination of this Agreement for
        any reason, directly or indirectly, solicit or recruit any
        employee of CBC to serve as an employee of, consultant to, or
        partner of Executive or any entity.

             (d)  Relief; Interpretation.  Executive agrees that CBC
        shall be entitled to injunctive relief for any breach by him of
        the covenants contained in Paragraphs 7(a), (b), or (c).  In the
        event that any provision of this Paragraph 7 shall be determined
        by any court of competent jurisdiction to be unenforceable by
        reason of its being extended over too great a period of time, too
        large a geographic area, or too great a range of activities, it
        shall be interpreted to extend only over the maximum period of
        time, geographic areas, or range of activities as to which it may
        be enforceable.  For purposes of this Paragraph 7, the term "CBC"
        shall mean CBC and any of its subsidiaries.

             (e)  Survival.  Executive's obligations under this
        Paragraph 7 shall survive termination of this Agreement.

             8.   Conflicting Agreements.  Executive hereby represents
        and warrants that the execution of this Agreement and the
        performance of his obligations hereunder will not breach or be in
        conflict with any other agreement to which he is a party or is
        bound, and that he is not now subject to any covenants against

                                      - 6 -




        competition or similar covenants which would affect the
        performance of his obligations hereunder.

             9.   Withholding.  All payments made by CBC under this
        Agreement shall be net of any tax or other amounts required to be
        withheld by CBC under applicable law.

             10.  Arbitration of Disputes.  Any controversy or claim
        arising out of or relating to this Agreement or the breach
        thereof shall be settled by arbitration in accordance with the
        laws of the Commonwealth of Massachusetts by three arbitrators.
        The party initiating arbitration shall nominate one arbitrator in
        the request for arbitration and the other party shall nominate a
        second in the answer thereto within thirty (30) days of receipt
        of the request.  The two arbitrators so named will then jointly
        appoint the third arbitrator.  If the answering party fails to
        nominate its arbitrator within the thirty (30) day period, or if
        the arbitrators named by the parties fail to agree on the third
        arbitrator within sixty (60) days, then such arbitrator shall be
        appointed by the American Arbitration Association in the City of
        Boston.  Such arbitration shall be conducted in the City of
        Worcester, Massachusetts in accordance with the rules of the
        American Arbitration Association, except with respect to the
        selection of arbitrators which shall be provided in this
        Paragraph 10.  Judgment upon the award entered by the arbitrators
        may be entered in any court having jurisdiction thereof.

             11.  Assignment, Successors and Assigns, etc.  Neither the
        employer nor Executive may make any assignment of this Agreement
        or any interest herein, by operation of law or otherwise, without
        the prior written consent of the other party; provided, however,
        that CBC may assign its rights under this Agreement without the
        consent of Executive in the event CBC shall hereafter consolidate
        with or merge into any other person, or transfer all or
        substantially all of its properties or assets to any other
        person.  In the event of the Executive's death prior to the
        completion by CBC of all payments due him under this Agreement,
        CBC shall continue such payments to the Executive's beneficiary
        designated in writing to CBC prior to his death (or to his
        estate, if he fails to make such designation).  This Agreement
        shall inure to the benefit of and be binding upon CBC and the
        Executive, their respective successors, executors,
        administrators, heirs and permitted assigns.

             12.  Enforceability.  If any portion or provision of this
        Agreement shall to any extent be declared illegal or
        unenforceable by a court of competent jurisdiction, then the
        remainder of this Agreement, or the application of such portion
        or provision in circumstances other than those as to which it is
        so declared illegal or unenforceable, shall not be affected
        thereby, and each portion and provision of this Agreement shall
        be valid and enforceable to the fullest extent permitted by law.



                                      - 7 -




             13.  Waiver.  No waiver of any provision hereof shall be
        effective unless made in writing and signed by the waiving party.
        The failure of any party to require the performance of any term
        or obligation of this Agreement, or the waiver by any party of
        any breach of this Agreement, shall not prevent any subsequent
        enforcement of such term or obligation or be deemed a waiver of
        any subsequent breach.

             14.  Notices.  All notices and other communications required
        or permitted hereunder shall be in writing and shall be
        delivered, mailed by first-class mail, postage prepaid, or sent
        by telex or facsimile with a mailed confirmation copy, addressed:
