                    CARACO PHARMACEUTICAL LABORATORIES, LTD.
                                 FORM 10-KSB

                                   PART I


ITEM 1. DESCRIPTION OF BUSINESS.

     Caraco Pharmaceutical Laboratories, Ltd. ("Caraco" or the "Corporation")
is a corporation organized under Michigan law in 1984, to engage in the
business of developing, manufacturing and marketing generic drugs for the
ethical (prescription) and over-the-counter (non-prescription or "OTC") 
markets.

     A generic drug is a pharmaceutical product which is the chemical and
therapeutic equivalent of a brand-name drug as to which the patent and/or
market exclusivity has expired. Generics typically sell at prices substantially
lower than the brand-name product.

     A significant source of funding for the Corporation to date has been from
private placement offerings and from the Economic Development Corporation of
the City of Detroit (the "EDC") which, pursuant to Section 108 of the Housing
and Community Development Act of 1974, loaned approximately $9.1 million to the
Corporation in accordance with a Development and Loan Agreement dated August
10, 1990 (the "EDC Agreement"), for use in funding the direct costs of
acquiring land and constructing thereon the Corporation's pharmaceutical
manufacturing facility and executive offices.  The facility was completed in
1992.

     Since 1993, Caraco's efforts have been spent developing its marketing and
sales capabilities, building sales and product acquisition relationships with
pharmaceutical purchasers, distributors and suppliers, and obtaining adequate
financing with which to fund its operations.


CURRENT STATUS OF CORPORATION

     The Corporation continues to sustain substantial operating losses, and
its ability to continue as a going concern is dependent on raising additional
funds and achieving profitable operations (See "Item 6. Management's Discussion
and Analysis of Financial Condition and Results of Operations.") The
Corporation is  currently in default on its loan from the EDC, and is
negotiating with the EDC to modify the terms of the Loan.  The EDC made a
proposal to the Corporation which terminated on March 17, 1997 and was subject
to various conditions which the Corporation could not satisfy.  Among other
things, the proposal included a deferral of payments on the loan for the period 



                                    - 3 -

<PAGE>   3



March 1996 through January 1999 designed to aid the Corporation in achieving
adequate cash flow during the next few years to assure Caraco's ability to both
fund its current operations and continue to develop products into the
marketplace. Monthly payments were to resume in February 1999 or sooner should
the Corporation reach profitability levels of $750,000 in any quarter through
March 31, 1998 and a level of $500,000 in the quarters ended June 30, 1998 and
September 30, 1998.  When payments were to be resumed, they would include a
portion of the deferral which would be apportioned over the remaining term of
the Loan.  Among other conditions, the offer was dependent on the Corporation   
entering into definitive agreements with Sun Pharmaceutical Industries Ltd., an
Indian based company  ("Sun Pharma"), for the contribution by Sun Pharma of
$7.5 million in equity to the Corporation and on the sale by Sun Pharma to the
Corporation of up to five ANDA products each year for four consecutive years.  
(See Discussion of Sun Pharma negotiations below).  The Corporation is
continuing to negotiate with the EDC, however, there is no assurance that a
modification agreement between the EDC and the Corporation will be consummated
or will be consummated pursuant to the terms of the above referenced proposal. 
If no agreement is consummated, the EDC may exercise all of the remedies
available to it including foreclosure on the Corporation's operating facility
and certain equipment.

     Sun Pharma and the Corporation entered into two non-binding letters of
intents in July 1996 pursuant to which Sun Pharma would make an initial cash
investment in Caraco Common Stock and pursuant to which Sun Pharma would sell
Caraco up to 20 generic pharmaceutical products for shares of Caraco Common
Stock.  Sun Pharma and the Corporation are currently negotiating proposed
agreements which, among other things, would provide that Sun Pharma invest
$7,500,000 over a period of one year in four installments and that Sun Pharma
sell up to 25 generic pharmaceutical products (either ANDAs (as defined
below) or DESI's (as defined below) with three (3) DESI's equal to one (1)
ANDA) over a period of 60 months in exchange for 544,000 shares of Common Stock
for each ANDA and 181,133 for each DESI.  The proposed agreement is
conditioned, among other things, on certain shareholders contributing an
aggregate of $1,000,000 in cash or Caraco Common Stock (up to a maximum of an
aggregate of 500,000 shares of Caraco Common Stock), approval from Indian
governmental agencies, approval of any EDC modification of the loan to Caraco
(see above), and the execution of definitive agreements.  There is no assurance
that agreements between Sun Pharma and the Corporation will be consummated or
will be consummated pursuant to the terms of the above referenced proposals. 
If no agreements are consummated, it is anticipated that the Corporation could
immediately commence bankruptcy proceedings under Chapter 7 of the Federal
Bankruptcy Code of 1978, as amended.

OVERVIEW OF THE GENERIC DRUG INDUSTRY


     Sales of generic drugs have increased in recent years because of a number
of factors including (i) modification of state laws to permit or require
substitution of generic drugs by pharmacists; (ii) enactment of Abbreviated New
Drug Applications (ANDAs) procedures for obtaining Food and Drug
Administration ("FDA") approval to manufacture generic prescription drugs;      
(iii) changes in governmental and third-party payor health care reimbursement
policies to encourage cost containment; (iv) increased acceptance of generic
drugs by physicians, pharmacists and consumers; and (v) the increasing number
of formerly patented drugs which have become available to generic competition. 
Moreover, a number of branded drugs with very significant sales volume will be
coming off-patent during the next four years.

CARACO'S PRODUCTS AND PRODUCT STRATEGY

     With the completion of its manufacturing facility in late 1992, Caraco's
immediate task was to put a range of products into the hands of its sales force
as quickly as practicable, broadcast its commencement of operations by offering
generics under its own label, and build its product line.  Its product line is
approximately five products in seven strengths in 19 package sizes.  In 1995
the Corporation developed and introduced Guaifenesin, Yohimbine and Salsalate
into its product line.  Most of these products are Drug Efficacy Study
Implementation ("DESI II") (product drugs that can be marketed based on past
marketing of an identical product that is not the subject of an approved drug
application).  In 1996 the Corporation received approval from the FDA to
manufacture Metoprolol Tartrate Tablets USP, 50 mg and 100 mg.  (See 
"Hexal-Pharma GmbH & Co., KG) Metoprolol Tartrate is the generic version of 
Ciba Geigy Pharmaceuticals Lopressor Tablets(R).  (See "Item 6. Management's 
Discussion and Analysis of Financial Condition and Results of Operations.") 
with respect to the limited sales of those products.

     The Corporation has been focusing on the development of its own
additional ANDA products, for which it filed one ANDA in 1994, two ANDAs in
1995 and one ANDA in 1997 (See Clonmel Chemicals Co. Ltd. (Ireland) and 
"Hexal-Pharma GmbH & Co., KG" below).  The Corporation received notice in 1996
that the Detroit Office of the FDA has recommended to the Center for Drug
Evaluation ("CDER") that the firm be approved to manufacture the remaining two
products for which they have made submissions. In addition the Detroit District
has also recommended approval for a product developed by Caraco which will be
manufactured and co-marketed with another generic drug company. (See "Apotex,
Inc." below). These filings are currently under review by the FDA and approval 
is expected in the first half of 1997. However, there is no assurance that the 
FDA will approve the ANDA or that such approval will occur in 1997.  





                                    - 5 -


<PAGE>   5


     The Corporation's strategy has been to forge strategic alliances with
major pharmaceutical companies with respect to products about to come
off-patent or recently off-patent.  Such arrangements frequently (but not
always) require that the generic company develop its own formulation and
manufacturing process for the product.  To date, the Corporation has entered
into formal or informal arrangements with five pharmaceutical companies.  Also,
see the discussion above ("Current Status of the Corporation") with respect to
the proposed sale of products by Sun Pharma to  the Corporation.

     R.P. SCHERER CORPORATION

     The Corporation's first strategic alliance was made with R.P. Scherer
Corporation, in the form of a supply contract, dated March 22, 1990, for the
Corporation's purchases of Nifedipine.  Under this agreement, the Corporation
purchases this product on commercial terms in bulk, packages it, and markets it
under its own label.  Sales of Nifedipine have decreased significantly since
the third quarter of 1995.  (See "Item 6. Management's Discussion and Analysis
of Financial Condition and Results of Operations.")
        
     HEXAL-PHARMA GMBH & CO., KG

     The Corporation's second strategic alliance is with Hexal-Pharma GmbH &
Co., KG, a German pharmaceutical company and its United States affiliate
(together, "Hexal").  Pursuant to an agreement dated as of October 1, 1993,
Hexal has agreed to convey to the Corporation the formulations, technology,
manufacturing processes and know-how, and other relevant information, and
to pay for the bioequivalency studies required for the preparation of ANDAs for
each of two specified generic drugs (the "Products").  The Corporation
undertook to prepare and file an ANDA for each Product and, when and if the
related ANDA is approved by the FDA (for which no assurance can be given), to
manufacture, market and sell the Products in the United States.  Hexal will
receive royalties on the yearly sales of each Product.  The Corporation filed
an ANDA in March 1995, in which it received approval from the FDA in December
1996.  (See "Caraco's Products and Product Strategy") Product is expected to be 
introduced to market during the second quarter of 1997.   Caraco is currently 
reviewing the data from the bioequivalency study of the other.  There is no 
assurance of when or if this other product will be filed and/or approved.  In 
addition, there is no certainty that the Corporation will be able to 
manufacture and sell either of these Products at a profit.

     In addition, the Corporation has granted to Hexal, for each Product (i) a
Sign-Up Option to purchase 100,000 shares of Common Stock at $3.50 a share; and
(ii) a Product Option to purchase a presently indeterminable number of shares
at an exercise price equivalent to their fair market value (as defined) when
the related 



                                    - 6 -

<PAGE>   6


ANDA for that Product is filed with the FDA. These options may be exercised and
payment for shares may be made only out of royalties (and any interest earned
on the royalties while held by the Corporation) payable to Hexal for sales of
the related Product.  To date there have been no sales of such Products and
accordingly no royalties earned and no  options exercised.

     The Agreement provides that the Corporation will hold all royalties until
receipt of Hexal's written instructions either to pay the royalties in cash or
to apply the royalties held to the exercise of the related options.  While a
Sign-Up Option remains unexercised, the Corporation will accrue the amount of
royalties attributable to the related Product.  If Hexal shall fail to deliver
to the Corporation, within 36 months after a given year's royalties on sales of
that Product become payable, its written instructions to apply those funds to
the exercise of the related Sign-Up Option, the number of shares subject to
that option shall be reduced by that    number of shares which the accrued
royalties paid in cash could have purchased. Thereafter, each year's royalties
for sales of a Product will be held by the Corporation for a maximum of five
years, during which period Hexal may direct that the royalties be paid to it in
cash or applied to the exercise of the related Product Option.  Any royalties   
paid in cash to Hexal may not thereafter be applied to the exercise of a
Sign-Up or a Product Option.

     The Agreement also provides that, for a period of ten years, or such
earlier date on which C. Arnold Curry shall no longer serve on the
Corporation's Board of Directors, or on which the Corporation shall sell
substantially all of its business and assets, or shall enter into a merger,
consolidation or similar transaction as a result of which the holders of the
Corporation's voting capital stock shall hold immediately thereafter less than
a majority of the voting capital stock of the surviving entity, Hexal, its
affiliates and associates (i) will not purchase any of the Corporation's Common
Stock, if and to the extent that such purchase would cause the percentage of    
outstanding shares owned beneficially by Dr. Curry to fall below 50.1%; (ii)
will not purchase shares of Common Stock, if and to the extent that such
purchase would cause beneficial ownership thereof by Hexal, its affiliates and
associates to exceed in the aggregate 35% of the Corporation's Common Stock
then outstanding; and (iii) will grant to the Dr. Curry a proxy to vote each
share of the Corporation's Common Stock beneficially owned by Hexal, its
affiliates and associates exceeding in the aggregate 10% of the Corporation's
Common Stock then outstanding.

     CLONMEL CHEMICALS CO., LTD. (IRELAND)

     On October 22, 1993, the Corporation entered into an agreement with
Clonmel Chemicals Co., Ltd. ("Clonmel"), pursuant to which 


                                    - 7 -

<PAGE>   7



Clonmel provided to the Corporation, with respect to each of two generic
pharmaceutical products, formulations that have been previously tested, the
formulation and manufacturing methods, in process controls, finished product
specifications, analytical methods and stability data required for the
Corporation to manufacture its own bio-batches (sample batches of the product
in amounts necessary for testing on humans) for use in the preparation and
filing with the FDA of ANDAs with respect to these products.  Caraco must bear
all costs of developing the products and filing the ANDAs.  With respect to
each of these products, the Corporation has paid Clonmel $10,000 on delivery of
complete files containing the foregoing data, and will pay another $20,000 on
completion of a successful bioequivalency study (which study will be at
Caraco's expense), and a final $20,000 upon receipt of FDA approval of the
related ANDA.  Clonmel has granted the Corporation the exclusive right to
manufacture and market these products in the United States, including its
territories and Puerto Rico, and in Canada; and the Corporation has agreed to
pay royalties to Clonmel on net sales (as defined) of these products for five
years from the date on which the marketing of the respective product commences. 
The bioequivalency study of one of the products was conducted and an
ANDA was filed January 1997.  (See "Item 6. Management's Discussion and 
Analysis or Plan of Operation.")  There can be no assurance that the 
Corporation will receive FDA approval of any ANDA which is filed or when FDA 
approval will be forthcoming; nor that the Corporation will be able to 
manufacture and sell either of these products profitably.

     APOTEX, INC.

     In June 1994, the Corporation announced its agreement to develop and
manufacture one or more generic drug products for Apotex U.S.A., the New York
based subsidiary of Apotex, Inc., reportedly the largest wholly-Canadian-owned
pharmaceutical company.  The Corporation has formulated the first product and
an ANDA was filed in March 1996.  (See "Caraco's Products and Product
Strategy") There is no assurance that the ANDA covering this product will 
receive FDA approval nor whether the  Corporation will be able to manufacture 
or sell the product profitably.  The agreement allows some selected marketing 
rights for the products to Caraco, in addition to the right of Apotex U.S.A. 
to market the product.

     SUN PHARMACEUTICAL INDUSTRIES LTD.

     In March 1996, the Corporation announced its agreement to produce and
market Sun Pharma generic anti-convulsant drug in the United States.  Caraco
and Sun Pharma will share research and development and registration efforts. 
There is no assurance that the ANDA covering this product will  receive FDA
approval nor 


                                    - 8 -

<PAGE>   8



whether the Corporation will be able to manufacture or sell the product
profitably.  However, if the ANDA is approved the Corporation will exclusively  
produce and market the product.  The agreement establishes an international
pipeline to utilize the Corporation's modern manufacturing facilities
specifically geared toward production for the generic drug market.  See
"Current Status of Corporation" for a discussion of additional proposed
transactions between Sun Pharma and Caraco.

OTHER AGREEMENTS

     In addition to the above mentioned agreements Caraco has signed two
agreements with a large multi-national pharmaceutical company to develop and
manufacture two products both of which are Non-Steroidal Anti-Inflammatory
Drugs (NSAID) for treating pain.  The agreements were executed in August and
September 1995 for a term of five years each with automatic renewal terms of 12
months thereafter.  All inventions, discoveries or trademarks are the property
of such multinational pharmaceutical company.

EDC FINANCING

     Pursuant to Section 108 of the Housing and Community Development Act of
1974, the EDC loaned approximately $9.1 million to the Corporation in 1990 in
accordance with the EDC Agreement.  These funds were used to pay the direct
costs of acquiring land and constructing thereon the Corporation's
pharmaceutical manufacturing facility and executive offices.  (See Item 2.
"Description of Property.")  In 1993, repayment of this indebtedness was
personally guaranteed by Dr. and Mrs. Curry.  (See "Current Status of
Corporation", "Management's Discussion and Analysis of Financial Condition and
Results of Operations" and Note 4 of Notes to Financial Statements.)

MARKETING

     Since 1993, the Corporation's marketing objective has been to create a
distribution system by which to obtain access to a wide range of purchasers of
generic pharmaceutical products. Internally, this requires at least a minimum
sales force; externally, it requires forging relationships, often contractual
in nature, with wholesalers, distributors, governmental agencies, and buying
groups, among others.  Management is aware that, despite any success in
creating these distribution links, sales volume will remain low until the
Corporation can offer a broader range of products needed by drug purchasers in
significant amounts.  In anticipation of its ability, through strategic
alliances and its own internal product development efforts to broaden its
product line, it has been putting distribution links in place.



                                    - 9 -

<PAGE>   9


     Drug wholesalers, with an estimated 75% of the drug market, comprise a
strategic link in the pharmacy distribution chain.  They are used by drug
manufacturers because they are a cost effective means of reaching thousands of
drug purchasers and are used by most drug purchasers because they constitute a
reasonably local, stocking source for hundreds or thousands of products from
multiple manufacturers.

     The top five drug wholesalers in 1995 accounted for over $41 billion in
sales.  Caraco's product line is now represented in the five top drug
wholesalers; McKesson Drug, Bergen Brunswig, Cardinal, FoxMeyer, and
AmeriSource.  For the year ended December 31, 1996 sales to Amerisource
accounted for 20% of gross sales of the Corporation.  On August 7, 1995 the
Corporation entered into an agreement with McKesson Drug Company pursuant to
which McKesson is to provide the Corporation with access to its existing
distribution networks.  For the year ended December 31, 1996 sales to McKesson
accounted for 17% of gross sales of the Corporation.  A gradually increasing
number of additional drug wholesalers now stock some or all of the
Corporation's products, partly as a result of the Corporation's arrangements
discussed below with buying groups.

     Federal and state agencies purchase a large amount of generic
pharmaceutical products.  All of the Corporation's products are now listed
for purchase at prices bid by the Corporation in the Federal Supply Schedule,
the Federal Bureau of Prisons Prime Vendor Program, the Veterans Administration
Prime Vendor Program, the Department of Defense and by various state agencies.
The Corporation has received and filled a gradually increasing volume of orders
from wholesalers designated as prime vendors under the federal programs for the
Bureau of Prisons, the Veterans Administration and the Department of Defense.

     A large number of buying groups of retail pharmacists, hospitals, nursing
homes and other regional or functionally similar categories of drug purchasers
use their members' combined purchasing power to induce drug manufacturers or
other vendors to submit bid prices at which their members may individually
purchase products through designated wholesalers.  The Corporation intends, as
part of its ongoing marketing efforts, to pursue arrangements with      
additional wholesalers and to expand its sales network of buying groups,
wholesalers, hospitals and hospital chains, nursing and retirement home groups,
state and federal government agencies, and retail pharmacies.  As and if the
Corporation's financial resources permit the increase in personnel, these
efforts will be expanded as discussed below.

SALES

     Still a small organization with a relatively small product line, Caraco
has only a small sales organization.  At the present 

                                   - 10 -

<PAGE>   10



time, the Corporation has two salaried salespersons.  As the product line grows
and sales increase, management contemplates a transition from a compensation    
structure providing for an annual salary to one emphasizing commission sales as
an obvious method both to provide appropriate incentives to the sales team and
also to control the ratio of sales expense to revenue.  Management intends to
increase its sales personnel as its resources permit.

RESEARCH AND DEVELOPMENT

     The development of new prescription ANDA products, including formulation,
stability testing and the FDA approval process, averages from two to five
years.  A drug is "bioequivalent" to a brand-name drug if the rate and extent
of absorption of the drug are not significantly different from those of the
brand-name drug.  Although the Corporation performs its own stability testing,
the Corporation's FDA-required testing for bioequivalence is done through
independent testing laboratories.  Each dosage level of a specific drug
generally requires separate bioequivalence studies, although more than one
dosage level can be included in a single ANDA.

     An outline of research and development expenses for 1996 and 1995 follows
(000's):

REGULATION

     The research and development, manufacture and marketing of the
Corporation's products are subject to extensive regulation by the FDA and by
other federal, state and local entities, which regulate, among other
things, research and development activities and the testing, manufacture,
labeling, storage, recordkeeping, advertising and promotion of pharmaceutical
products.

     The Federal Food, Drug and Cosmetic Act, the Public Health Services Act,
the Controlled Substances Act and other federal statutes and regulations govern
or influence all aspects of the Corporation's business.  Noncompliance with
applicable requirements can result in fines and other judicially imposed
sanctions, including product seizures, injunction actions and criminal
prosecutions.  In addition, administrative remedies can involve voluntary 
recall of products, and the total or partial suspension of products as well as
the refusal of the government to approve 



                                   - 11 -


<PAGE>   11


pending applications or supplements to approved applications.  The FDA also has
the authority to withdraw approval of drugs in accordance with statutory
due process procedures.

     FDA approval is required before any dosage form of any new unapproved
drug, including a generic equivalent of a previously approved drug, can be
marketed.  All applications for FDA approval must contain information relating
to product formulation, stability, manufacturing processes, packaging, 
labeling and quality control.  To obtain FDA approval for an unapproved new
drug, a prospective manufacturer must also demonstrate compliance with the
FDA's current good manufacturing practices ("cGMP") regulations as well as
provide substantial evidence of safety and efficacy of the drug product. 
Compliance with cGMP'S is required at all times during the manufacture and
processing of drugs.  Such compliance requires considerable Corporation time
and resources in the areas of production and quality control.

     There are generally two types of applications that would be used to obtain
FDA approval for pharmaceutical products:

        New Drug Application ("NDA").  Generally, the NDA procedure is required
   for drugs with active ingredients and/or with a dosage form, dosage strength
   or delivery system of an active ingredient not previously approved by the
   FDA.  Caraco does not expect to submit an NDA in the foreseeable future.

        Abbreviated New Drug Application ("ANDA").  The Waxman-Hatch Act
   established a statutory procedure for submission of ANDAs to the FDA
   covering generic equivalents of previously approved brand-name drugs.  Under
   the ANDA procedure, an applicant is not required to submit complete reports
   of preclinical and clinical studies of safety and efficacy, but instead is
   required to provide bioavailability data illustrating that the generic drug
   formulation is bioequivalent to a previously approved drug.  Bioavailability
   measures the rate and extent of absorption of a drug's active ingredient and
   its availability at the site of drug action, typically measured through
   blood levels.  A generic drug is bioequivalent to the previously approved
   drug if the rate and extent of absorption of the generic drug are not
   significantly different from that of the previously approved brand-name
   drug.

     The FDA may deny an ANDA if applicable regulatory criteria are not
satisfied. Product approvals may be withdrawn by the FDA if compliance with
regulatory standards is not maintained or if new evidence demonstrating that
the drug is unsafe or lacks efficacy for its intended uses becomes known after
the product reaches the market.





                                    - 12  -

<PAGE>   12

     Changes in FDA policy and requirements have increased the time and expense
involved in obtaining ANDA approvals and in complying with FDA's cGMP
standards. The ANDA filing and approval process now averages approximately 18
months.

     The Generic Drug Enforcement Act of 1992 establishes penalties for
wrongdoing in connection with the development or submission of an ANDA by
authorizing the FDA to permanently or temporarily bar companies or individuals
from submitting or assisting in the submission of an ANDA, and to temporarily
deny approval and suspend applications to market off-patent drugs.  The FDA has
authority to withdraw approval of an ANDA under certain circumstances and to
seek civil penalties.  The FDA can also significantly   delay the approval of a
pending ANDA under certain circumstances and to seek civil penalties.  The FDA
can also significantly delay the approval of a pending ANDA under its "Fraud,
Untrue Statements of Material Facts, Bribery, and Illegal Gratuities Policy."
Manufacturers of drugs must also comply with the FDA's cGMP standards or risk
sanctions such as the suspension of manufacturing or the seizure of drug
products and the FDA's refusal to approve additional ANDAs.

     The Corporation was subject to two FDA inspections and one Drug
Enforcement Administration ("DEA") inspection in 1996.  The first FDA
inspection was a routine inspection for cGMP compliance as well as a
pre-approval inspection for two ANDAs.  The second FDA inspection was a
pre-approval inspection for another ANDA.  NO FDA 483s were issued as a result
of either inspection and the District recommended approval of the ANDAs.  These
recommendation were forwarded to the FDA reviewing staff in Washington, DC.

     The DEA inspection was a routine inspection conducted bi-annually.  No
deviations from compliance were noted at the conclusion of this inspection.
Although management believes that the Corporation is in substantial compliance
with the FDA's cGMP's, there can be no assurance that, as the Corporation
endeavors to engage in increasing drug manufacturing activities, it will be
able to maintain a successful compliance program.  If it should fail to do so,
it may be the target of any of the range of enforcement remedies available to
the government described above.

     Each domestic drug product manufacturing establishment must be registered
with the FDA.  Establishments handling controlled substances must be licensed
by the United States Drug Enforcement Administration.

     The Corporation is also subject to regulation under other federal, state
and local regulations regarding work place safety, environmental protection and
hazardous substance controls, among others.  Specifically, the Corporation is
licensed by the Michigan Board of Pharmacy as a manufacturer and wholesaler of
prescription drugs and as a distributor of controlled substances.  It is also 

                                   - 13 -

<PAGE>   13



licensed by the Michigan Liquor Control Commission to use alcohol in the
manufacture of drugs.

     The Corporation believes that it is in substantial compliance with all
environmental laws.

SUPPLIERS AND MATERIALS

     The principal components used in the Corporation's business are active and
inactive pharmaceutical ingredients and certain packaging materials. Many of
these components are available only from sole source suppliers. Development and
approval of the Corporation's pharmaceuticals are dependent upon the
Corporation's ability to procure active ingredients and certain packaging
materials from FDA approved sources.  Because the FDA approval process requires
manufacturers to specify their proposed suppliers of active ingredients and
certain packaging materials in their applications, FDA approval of a new
supplier would be required if active ingredients or such packaging materials
were no longer available from the specified supplier.  The qualification of a
new supplier would delay the manufacture of the drug involved.  (See "R.P.      
Scherer Corporation" above with respect to its supply of Nifedipine to the
Corporation).

     Although to date no significant difficulty has been encountered in
obtaining components required for products and sources of supply are considered
adequate, there can be no assurance that the Corporation will continue to be
able to obtain components as required.

COMPETITION

     The market for generic drugs is highly competitive.  There is intense
competition in the generic drug industry in the United States which is eroding
price and profit margins.  The Corporation competes with numerous
pharmaceutical manufacturers, including both generic and brand-name
manufacturers, many of which have been in business for a longer period of time
than the Corporation, have a greater number of products on the market and have
considerably greater financial, technical, research, manufacturing, marketing
and other resources.

     The principal competitive factor in the generic pharmaceutical market is
the ability to be the first company, or among the first companies, to introduce
a generic product after the related patent expires.  Other competitive factors
include price, quality, methods of distribution, reputation, customer service
(including maintenance of inventories for timely delivery) and breadth of
product line.  Approvals for new products may have a synergistic effect on a
company's entire product line since orders for new products are frequently
accompanied by, or bring about, orders for 


                                   - 14 -

<PAGE>   14



other products available from the same source.  The Corporation believes that
price is a significant competitive factor, particularly as the number of        
generic entrants with respect to a particular product increases.  As
competition from other manufacturers intensifies, selling prices typically
decline.

EMPLOYEES

     As of December 31, 1996, the Corporation had 31 full-time employees, of
which four are engaged in research and development, six in quality assurance,
five in quality control, three in administration, four in sales and marketing,
two in finance and seven in manufacturing.  Most of the Corporation's 
scientific and engineering employees have had prior experience with     
pharmaceutical or medical products companies.  No employee is represented by a
union, and the Corporation has never experienced a work stoppage.

SEC INVESTIGATION

     As previously disclosed, during the year ended December 31, 1994 the
Corporation determined that approximately $514,000 of Corporation funds had
been misappropriated by the Corporation's former controller, a son of the
Corporation's former Chairman, Emeritus.  The Corporation has made filings
about this matter with the Securities and Exchange Commission (the "SEC").  The
SEC has conducted an investigation into the matter.  On November 1, 1996, the
Corporation, through its Washington DC Legal Counsel, was notified by the SEC
that its Enforcement Division has tentatively decided not to recommend that the
Commission authorize an enforcement action against the Corporation.  The SEC
further advised that it nevertheless was possible that an action against the
Corporation may ultimately result from the investigation.  The SEC's
investigation had revealed that the defalcation which was reported October 18,
1994 had also occurred in 1993, as well as in the first half of 1994, and that
the 1993 defalcation had totaled at least an additional $300,000.  It is also
possible that the Commission might institute an enforcement proceeding
against one or more former employee(s) of the Corporation who are no longer
associated with the Corporation.

PRODUCT LIABILITY AND INSURANCE

     The Corporation currently has in force general and product liability
insurance, with coverage limits of $3 million per incident and in the
aggregate.  The Corporation's insurance policies provide coverage on a claim
made basis and are subject to annual renewal.  Such insurance may not be
available in the future on acceptable terms or at all.  There can be no
assurance that the coverage limits of such policies will be adequate to cover
the Corporation's liabilities, should they occur.

ITEM 2. DESCRIPTION OF PROPERTY.

     The Corporation's 70,611 square foot facility, which was designed and
constructed to the Corporation's specifications and completed in 1992,
contains its production, packaging, research and executive operations.  It is
on a four acre site acquired by the Corporation from the EDC of the City of
Detroit.  This manufacturing facility has a special building and systems
design, with each processing area equipped with independent zone and air
handling units to provide temperature and humidity control to each room.  These
air handling units are designed to prevent product cross contamination through
the use of pre-filter and final HEPA filter banks.  All processing air quarters
are maintained in a negative pressure mode using laminar air flow design.  This
system of air flow provides a measurable control of air borne particulate
entrapment in each room.

     Reference is made to the discussion of the funding of the Corporation's
facility by the Economic Development Corporation of the City of Detroit in Item
1 above.  The Corporation's obligation to the EDC pursuant to its note and that
certain Development and Loan Agreement dated August 10, 1990 is collateralized,
among other things, by a mortgage on the Corporation's property.  The EDC
subordinated its position in the Corporation's facility, subject to certain
conditions, in an amount up to $3 million.  The Agreement also contains certain
restrictive covenants regarding the activities of the Corporation.  The
Corporation has not made any of the required monthly principal and interest
payments since March of 1996.  The Corporation is negotiating with the EDC to
modify the terms of the loan and is seeking private equity financing to 
rectify this loan default. (See "Item 1 - Current Status of the Corporation".)

     Environmental segregation of individual rooms within a particular zone is
accomplished by the use of duct HEPA filter booster fan units that facilitate
the isolation and confinement of room activities.  These special dynamics
provide an added dimension and flexibility in product selection and processing
techniques. The design allows all processing areas, with a modest capital
addition, to be equipped with purified breathing air systems to facilitate the
use of custom handling and control as product requirements warrant.  That
capital addition will not be made until consummation of a strategic alliance,   
with specific product requirements, which would make such addition financially
sound.

ITEM 3. LEGAL PROCEEDINGS.

     The Corporation is not a party to any litigation which, individually or in
the aggregate, is believed to be material to the Corporation's business.

corporate existence.

     10. REMEDIES.   In the event of the occurrence of any default, Secured
Party may exercise its rights under law, including by way of enforcement under
the Uniform Commercial Code in effect in the State of Michigan at the date of
this Agreement.  Secured Party may enter Debtor's premises without legal process
and remove the Collateral or require the Debtor to assemble the Collateral and
make it available to Secured Party at a place within the State of Michigan
designated by Secured Party.  If it so elects, Secured Party may and is hereby
empowered, without legal process, to enter any premises where the Collateral may
be kept and take exclusive possession of it on those premises with or without a
custodian.  Secured Party may thereafter sell the Collateral at one or more
public or private sales, on or away from Debtor's business premises.  Unless the
Collateral is perishable, threatens to decline speedily in value or is of a type
customarily sold on a recognized market, Secured Party shall give Debtor
reasonable notice of the time and place of any public sale thereof, or of the
time after which any private sale or any other intended disposition thereof is
to be made.  The requirement of reasonable notice shall be met if notice is
mailed to Debtor, postage prepaid, by first class certified mail, return receipt
requested, at least five (5) days prior to the date of the proposed sale or
disposition.  At any such sale, Secured Party may in its absolute discretion
sell and dispose of all the right, title, and interest of Debtor in and to any
of the Collateral. Any such sale may be for cash or for credit, and Secured
Party may be the purchaser.  Out of the monies arising from the sale and/or
collection of the Collateral, Secured Party shall retain any and all sums then
owing to Secured Party, including all additional advances and debts, and all
costs, fees, charges and expenses in connection therewith, with interest,
including reasonably attorneys fees, disbursements as herein defined, premiums
on bonds, custodian's fees, fees of public officers, auctioneer's fees, plus
advertising and labor, disbursements for use and occupancy of premises and any
and all other disbursements made by Secured Party in connection with the taking,
maintaining, storage and disposing of the Collateral, tendering the excess (if
any) to Debtor or its successors or assigns.  If for any reason the Collateral
shall fail to satisfy all of the foregoing items, Debtor shall pay to Secured
Party the resulting deficiency upon demand.

     11. SEVERABILITY.   If any provision of this Agreement shall for any reason
be held to be invalid or unenforceable, that invalidity or unenforceability
shall not affect any other provision hereof, and this Agreement shall be
construed as if the invalid or unenforceable provision had never been contained
herein.

     12. NOTICES. All notices to the parties under this Agreement shall be
sufficient if mailed by certified mail, return receipt requested with sufficient
prepaid postage, to the parties at their addresses appearing at the beginning of
this Agreement, or at such other address as they shall designate in writing as
provided by this paragraph. Notice so directed and posted shall be effective
upon receipt or upon first attempted delivery or upon posting if proof of
posting is obtained (without regard to who receives or signs for such notice and
without regard to whether or not such notice is actually delivered).

"Subordinating Creditors") and CARACO PHARMACEUTICAL LABORATORIES, LTD., a
Michigan corporation, whose address is 1150 Elijah McCoy Dr., Detroit, Michigan
48202 (the "Borrower").

pursuant to that certain Secured Promissory Note of even date herewith and
Security Agreement of even date herewith (the "Sun Loan Agreements").

        Lender desires to loan $350,000 to Borrower, and Subordinating
Creditors desire to accommodate Lender and Borrower by subordinating their
right to payment and subordinating their security interests under their Loan
Documents (herein collectively referred to as the "Property").

        NOW, THEREFORE, as an inducement to and in consideration of the
advancement of funds by Lender, the parties agree as follows:

        1.  SUBORDINATION OF SUBORDINATED DEBT.  The $890,000 in indebtedness
of Borrower to Subordinating Creditors, and all payments of monies by Borrower
to Subordinating Creditors due or to become due pursuant to the Loan Documents
(hereinafter referred to as "Subordinated Debt") and all security interests
granted to Subordinating Creditors in the Property for said Subordinated Debt
shall be subordinated and postponed to the prior payment and satisfaction in
full of any and all indebtedness of Borrower to Lender pursuant to the Sun Loan
Agreements. 

        2.  SURVIVAL.  This subordination by Subordinating Creditors of the
Subordinated Debt shall survive and shall remain in full force and effect in
the event of any administration of the Property and/or affairs of Borrower
arising from any assignment for the benefit of creditors, bankruptcy,
receivership, liquidation or other like proceedings; and no delay, forbearance,
or omission by Lender in the exercise of any right or power accruing to it upon
any default in the performance hereof by the other parties hereto shall impair
any such right or power or shall be construed to be a waiver of any such
default or acquiescence therein.

the same with any other funds and shall pay over and deliver such payment to
Lender immediately, to be applied upon the indebtedness of Borrower to Lender
under the Sun Loan Agreements.

        4.  ACCELERATION.  In the event that Borrower, in violation of this
Agreement, shall make payment of any part of the Subordinated Debt, whether
such payment be in cash or otherwise, then and in such event, all Indebtedness

that they shall take whatever steps are necessary, from time to time, in the
opinion of lender, to evidence and acknowledge and/or confirm and/or consent to
the priority, perfection and validity of the security interests of Lender in
the Property, including but not by way of limitation, amendment to their
Financing Statement(s) previously filed with respect to the Property.

and acknowledge that in the event of default of Borrower to Subordinating

herein restricted) to give prompt notice thereof to Lender. 

        9.  TRANSFER.  Subordinating Creditors hereby transfer and assign to
Lender, as collateral security for any and all said obligations of Borrower to
Lender, all of the said claims or demands of Subordinating Creditor against
Borrower, with full right on the part of Lender, in its own name or in the name
of Subordinating Creditors, to collect and enforce said claims, by suit, proof
of debt in bankruptcy, or other liquidation proceedings, or otherwise. Should

Amount:  $350,000                                            Detroit, Michigan
                                                             December 23, 1996

Lender may designate in writing, the principal sum of Three Hundred Fifty
Thousand and 00/100 ($350,000) Dollars, together with interest at 10.0% per
annum.  This Secured Promissory Note (the "Note") shall mature, and all
principal outstanding hereunder, together with all accrued and unpaid interest
thereon shall be due and payable on (A) the earlier of (i) March 27, 1997, (ii)
the closing of a transaction pursuant to which Sun Pharmaceutical Industries
Limited ("Sun Pharmaceutical") or an affiliate acquires 5.3 million shares of
the Common Stock of Borrower (the "Proposed Transaction") or (iii) 20 days after
delivery of a written notice by Sun Pharmaceutical to Borrower that Lender does

obligation which Sun Pharmaceutical may hereafter incur in writing or (B) in any
event, upon the occurrence of a Default as defined pursuant to the Security
Agreement (as defined below).  In the event the outstanding principal and
interest hereunder are not paid when due, then until such principal balance or
accrued interest is paid, the outstanding principal balance and all accrued but

charges which may or might be characterized as interest) exceed the maximum rate
permitted to be charged under applicable law.  Should Lender or any other holder
of this Note receive any payment which is or would be in excess of that
permitted to be charged under applicable law, such payment shall have been, and
shall be deemed to have been made in error and shall be held as additional cash
collateral for the indebtedness evidenced by this Note.

                                       2

<PAGE>   3



modified, renewed, extended, amended or replaced from time to time, and shall
pay all amounts and perform all obligations required under or pursuant to this

and covenants that:


          A.   The Collateral is or will be owned by Debtor and except with
               respect to (i) collateral securing a $65,000 loan from Jay F.
               Joliat and/or his affiliates to the Company (which loan is to be
               repaid from the proceeds of the $350,000 loan from the Secured
               Party), and (ii) the collateral securing the Subordinated Debt as
               defined in that certain Subordination Agreement of even date
               herewith, the Collateral is not subject to any security
               interests, liens or encumbrances, charges, restrictions or claims
               except as created by 




                                      3


<PAGE>   4



               this Agreement, and Debtor will defend the Collateral against the
               claims and demands of all persons;

          B.   Debtor will execute, and will pay all costs of filing of, any
               financing, continuation or termination statement with respect to
               the security interest created by this Agreement deemed necessary
               or desirable by the Secured Party;

          C.   Debtor shall from time to time, at the expense of Debtor, execute
               and deliver all further instruments and documents, and take all
               further actions, that the Secured Party may reasonably deem
               necessary or desirable, in order to perfect and protect any
               security interest granted or purported to be granted hereby or to
               enable the Secured Party to exercise and enforce its rights and
               remedies hereunder with respect to any Collateral.

          D.   Debtor hereby authorizes the Secured Party to file one or more
               financing or continuation statements, and amendments thereto,
               relative to all or any part of the Collateral, with or without
               Debtor's signature thereon.

          E.   Debtor was incorporated under the name J-Mac Domestic, Inc.,
               changed its name to Caraco, Inc. until changing its name to its
               current name, and Debtor's chief executive office and sole place
               of business is located at 1150 Elijah McCoy Drive, Detroit,
               Michigan 48202.

          F.   Debtor is a corporation duly organized under the laws of
               Michigan, validly existing and in good standing and has full
               corporate power to own, operate and lease its properties and to
               carry on its business as now conducted. Debtor is qualified to do
               business in all jurisdictions where the nature of its activities
               would make such qualification necessary and the failure to so
               qualify would have a material and adverse affect on the Debtor.

          G.   Debtor has all power, statutory and otherwise, to execute and
               deliver this Security Agreement, the Note and the Subordination
               Agreement, and the execution hereof and thereof, and Debtor's
               performance of its obligations hereunder and thereunder, have
               been approved by all appropriate corporate action.  Such
               agreements and documents constitute the legal, valid and binding
               obligation of Debtor, enforceable against such Debtor in
               accordance with its terms.

          H.   The equipment listed on Schedule A hereto is not subject to the
               lien of the Economic Development Corporation of the City of
               Detroit and Debtor reasonably believes the Equipment has a fair
               market value of not less than $1.5 million.

          I.   Debtor shall not move the Collateral or change Debtor's name,
               identity or corporate structure unless it has received Secured
               Party's prior written consent thereto and has taken all action
               necessary or reasonably requested by the Secured Party to amend
               any financing statement or continuation statement filed with
               respect to the Collateral in connection therewith.

          J.   The execution, delivery and performance of this Agreement and the
               other Loan Documents by Debtor and its performance of its
               obligations hereunder and thereunder does not conflict with or
               result in any violation of or constitute a breach or default
               under (i) any term of the Articles of Incorporation or Bylaws of
               Debtor, (ii) any indenture, agreement instrument, order, judgment
               or decree to which Debtor is a party, bound or subject or to
               which any of the assets or business of Debtor are subject, (iii)
               any law, statute or regulation of any governmental or regulatory
               body.

          K.   No approval or consent of the execution, delivery and performance
               by the Debtor of this Agreement, the Note, and the other Loan
               Documents is required by law or by the Debtor's existing Articles
               of Incorporation or Bylaws or by any contract, indenture,
               agreement, instrument, order, judgment or decree to which the
               Debtor is a party or otherwise bound or to which any of its
               property or business is subject, or by any indebtedness of the
               Debtor.

          L.   There are no actions, proceedings or investigations pending or,
               to the knowledge of the Debtor, threatened against the Debtor
               before any court, administrative agency or other governmental or
               regulatory authority.  Neither the Debtor nor its property and
               assets is subject to any judicial or administrative order,
               judgment or decree which could have a material adverse effect on
               the Debtor, its business, properties, condition (financial or
               otherwise) or prospects.  The Debtor has not violated any
               federal, state or local laws, regulations or orders.

     9.   DEFAULT.  The following shall constitute defaults (each a "Default")
under this Agreement:

               of competent jurisdiction of a custodian, trustee or receiver to
               take custody or dispose of any substantial portion of the assets
               of Debtor pursuant to any involuntary proceeding and either (i)
               Debtor shall indicate approval of, consent to, or acquiescence to
               such appointment, or (ii) such custodian, trustee, or receiver
               shall not be discharged within thirty (30) days; or Debtor shall
               voluntarily seek protection from creditors under any applicable
               state or federal bankruptcy, liquidation or dissolution,
               insolvency, or debt reorganization laws; or any of Debtor's
               creditors shall institute any proceeding against Borrower under
               any applicable state or federal bankruptcy, liquidation or
               dissolution, insolvency, or debt reorganization laws, and the
               same shall not be dismissed or discharged within thirty (30)

                                      6

<PAGE>   7


     G.   Any party to the Subordination Agreement (other than Secured Party)
          shall default in the performance of any covenant, agreement, condition
          or provision thereof.


     10.  REMEDIES.   In the event of the occurrence of any default, Secured
Party may exercise its rights under law, including by way of enforcement under
the Uniform Commercial Code in effect in the State of Michigan as in effect from
time to time.  Secured Party may enter Debtor's premises without legal process
or any obligation to pay rent and remove the Collateral or require the Debtor to
assemble the Collateral and make it available to Secured Party at a place within
or outside the State of Michigan designated by Secured Party.  If it so elects,
Secured Party may and is hereby empowered, without legal process, to enter any
premises where the Collateral may be kept and take exclusive possession of it on
those premises with or without a custodian.  Secured Party may thereafter sell
the Collateral at one or more public or private sales, on or away from Debtor's
business premises.  Unless the Collateral is perishable, threatens to decline
speedily in value or is of a type customarily sold on a recognized market,
Secured Party shall give Debtor reasonable notice of the time and place of any
public sale thereof, or of the time after which any private sale or any other
intended disposition thereof is to be made.  The requirement of reasonable
notice shall be met if notice is mailed to Debtor, postage prepaid, by first
class certified mail, return receipt requested, at least five (5) days prior to
the date of the proposed sale or disposition.  At any such sale, Secured Party
may in its absolute discretion sell and dispose of all the right, title, and
interest of Debtor in and to any of the Collateral. Any such sale may be for
cash or for credit, and Secured Party may be the purchaser.  Secured Party shall
have the right to (i) demand payments of the Accounts, (ii) enforce payment of
the Accounts by legal proceedings or otherwise, (iii) exercise all of Debtor's
rights and remedies with respect to the collection of the Accounts, (iv) settle,
adjust or compromise any legal proceedings brought to collect the Accounts, (v)
if permitted by law, sell or assign the Accounts upon such terms, for such
amounts and at such time or times as the Secured Party deems advisable, (vi)
discharge and release the Accounts, (vii) prepare, file and sign Debtor's name
on any proof of claim in bankruptcy or similar document against any account
debtor, (viii) prepare, file and sign any Debtor's name on any notice of lien,
assignment or satisfaction of lien or similar document in connection with the
Accounts, (ix) do all acts and things necessary in the Secured Party's sole
discretion, to fulfill Debtor's obligations under this Security Agreement, (x)
endorse the name of Debtor upon any Chattel Paper, Document, Instrument,
invoice, freight bill, bill of lading or similar document or agreement relating
to the Collateral, (xi) use Debtor's stationery and sign the name of Debtor to
verifications of the Accounts and notice thereof to Account debtors, and (xii)
use the information recorded on or contained in any data processing equipment
and computer hardware, software and source codes relating to the Collateral to
which Debtor has access.  Out of the monies arising from the sale and/or
collection of the Collateral, Secured Party shall retain any and all sums then
owing to Secured Party, including all additional advances and debts, and all
costs, fees, charges and expenses in connection therewith, with interest,
including reasonable attorneys fees, disbursements, premiums on bonds,
custodian's fees, fees of public officers, auctioneer's fees, plus advertising
and labor, disbursements for use and occupancy of premises and any and all other
disbursements made by Secured Party in connection with the taking, maintaining,
storage 


                                      7

<PAGE>   8



and disposing of the Collateral, tendering the excess (if any) to Debtor or its
successors or assigns.  If for any reason the Collateral shall fail to satisfy
all of the foregoing items, Debtor shall pay to Secured Party the resulting
deficiency upon demand.  Secured Party's remedies shall be cumulative and
non-exclusive to the fullest extent permitted by law.

     11.  DISCRETIONARY RIGHTS.  Exercise of or omission to exercise any right
of the Secured Party shall not affect any other subsequent right of the Secured
Party to exercise the same and the waiver of any default by the Secured Party
shall not be deemed a waiver of any subsequent Default.

     12.  SEVERABILITY.   If any provision of this Agreement shall for any
reason be held to be invalid or unenforceable, that invalidity or
unenforceability shall not affect any other provision hereof, and this Agreement
shall be construed as if the invalid or unenforceable provision had never been
contained herein.

     13.  NOTICES. All notices to the parties under this Agreement shall be
sufficient if mailed by certified mail, return receipt requested with sufficient
prepaid postage, to the parties at their addresses appearing at the beginning of
this Agreement, or at such other address as they shall designate in writing as
provided by this paragraph.  Notice so directed and posted shall be effective
upon receipt.

     14.  GOVERNING LAW.  This Agreement shall be governed by and interpreted in
accordance with the laws of the State of Michigan.

     15.  COUNTERPARTS.  This Agreement may be executed in multiple
counterparts, each of which shall be deemed an original and all of which shall
constitute one agreement.  The signature of any party to any counterpart shall
be deemed to be a signature to, and may be appended to, any other counterpart.

     16.  CAPTIONS.  Captions to paragraphs contained in this Agreement, other
than in Paragraph 1.E., are for convenience only and are entirely without
substantive effect.

     17.  SUCCESSORS.  This Agreement shall be binding upon, and the benefits
hereof shall inure to, the parties hereto and their respective successors and

                         SECURED SHORT TERM DEMAND NOTE

FOR VALUE RECEIVED, the undersigned promises to pay to the order of the
Rosemary Joliat Living Trust DTD 4/12/88 as amended, the sum of Sixty Five
Thousand ($65,000) Dollars, together with interest of 10.0% per annum of the
unpaid balance, with such interest accruing daily.  The entire unpaid principal
and any accrued interest shall be immediately payable UPON DEMAND of any holder
of this note.  The automatic repayment of this note shall coincide with the
receipt of the anticipated $350,000 loan from Sun Pharma Global, Inc.  In no
event however, shall the total borrowed amount along with all accrued interest
be repaid any later than December 31, 1996.  It is agreed that this secured
short term demand note shall hold priority as to repayment over any other
account of trade currently payable, or any other loans, either secured or
unsecured, currently outstanding to the extent allowed by law.

This note is secured by a Security Agreement of the even date herewith
("Security Agreement"), which security agreement may not be amended or changed.
Reference is hereby made to the Security Agreement regarding the security
given for this instrument.

Failure to repay this note along with all interest accrued on the timetable
described above shall constitute default under this agreement.  If a default
occurs, as such term is defined in the Security Agreement, the Borrower
promises to pay the costs of collection of this note, including Lender's
reasonable attorneys' fees.

Borrower, for itself, its successors, heirs and assigns, expressly waives
presentment for payment, demand, notice of non-payment, notice of protest and
protest of this Note, and diligence in collection or bringing suit.  The
liability of Borrower to Lender shall be absolute and unconditional, without
regard to the liability of any other party.

This Note and all rights of Lender hereunder shall inure to the benefit of
Lender's assigns, successors, heirs or beneficiaries and shall bind Borrower
and its successors and assigns.

This Note shall be governed by, and construed in accordance with the laws of
the State of Michigan.  If any provision of this Note is held by a court of     
competent jurisdiction to be invalid, void or unenforceable, the remaining
provisions shall nonetheless continue in full force without impairment or
invalidation in any way.

IN WITNESS WHEREOF, the Borrower has caused this Note to be executed as of the
date and year indicated below the Borrowers signature.

                            SECURED PROMISSORY NOTE

Amount:  $100,000                                            Detroit, Michigan
                                                             January 30, 1997




     FOR VALUE RECEIVED, Caraco Pharmaceutical Laboratories, Ltd., a Michigan
corporation ("Borrower"), promises to pay to the order of Jay F. Joliat, as

April 8, 1982, the address of which is 1411 N. Woodward, Suite 300, Birmingham,
Michigan 48109  ("Lender"), or at such other place as Lender may designate in
writing, the principal sum of One Hundred Thousand and 00/100 ($100,000)
Dollars, together with interest at 10.0% per annum payable in cash or shares of
Common Stock of Borrower as determined in the sole discretion of Borrower.
This Secured Promissory Note (the "Note") shall mature, and all principal
outstanding hereunder, together with all accrued and unpaid interest thereon
shall be due and payable on (A) the earlier of (i) March 27, 1997, (ii) the
closing of a transaction pursuant to which Sun Pharmaceutical Industries

the Common Stock of Borrower (the "Proposed Transaction") or (iii) 20 days
after delivery of a written notice by Sun Pharmaceutical to Borrower that
Lender does not intend to proceed with and/or continue negotiations regarding
the Proposed Transaction, unless such failure to proceed constitutes a breach
of any legal obligation which Sun Pharmaceutical may hereafter incur in writing
or (B) in any event, upon the occurrence of a Default as defined pursuant to
the Security Agreement (as defined below).  In the event the outstanding
principal and interest hereunder are not paid when due, then until such
principal balance or accrued interest is paid, the outstanding principal
balance and all accrued but unpaid interest thereon shall bear interest at the
rate 12% per annum.

     Notwithstanding any other provision of this Note or any other agreement
between Borrower and Lender, nothing herein shall require the Borrower to pay,
or the Lender to accept, interest in an amount which subjects the holder of
this Note to any penalty or forfeiture under applicable law, and in no event
shall the total of all charges payable hereunder (whether of interest or of
such other charges which may or might be characterized as interest) exceed the
maximum rate permitted to be charged under applicable law.  Should Lender or
any other holder of this Note receive any payment which is or would be in
excess of that permitted to be charged under applicable law, such payment shall
have been, and shall be deemed to have been made in error and shall be held as
additional cash collateral for the indebtedness evidenced by this Note.

or conditions of any nature imposed by any governmental body, and all payments
shall be first applied to any costs and expenses permitted hereunder, then

remainder to be applied to any unpaid principal.

time without premium or penalty.  All payments shall be made in lawful money of
the United States of America.

     This Note is secured by a Security Agreement of even date herewith
("Security Agreement") and an Inter-Creditor Agreement of even date herewith
("Inter-Creditor Agreement"), as each may be amended from time to time.
Reference is hereby made to the Security Agreement and the Inter-Creditor
Agreement with respect to the security given for this instrument.

     Borrower agrees to pay to Lender (or the holder of this Note) (a) all
costs and expenses incurred by the Lender or other holder hereof in collecting
hereon, whether through reorganization, bankruptcy, any other proceeding or
otherwise, (b) attorneys' and consultants fees and expenses in connection with
any proposed refinancing or restructuring of the credit provided in this Note
in the nature of a "work-out" and (c) all fees and expenses, including
attorneys fees, incurred in connection with the collection of this Note or the
enforcement of any of its rights under the Security Agreement or the
Inter-Creditor Agreement.

     Borrower, for itself, its successors, heirs and permitted assigns, and any
other parties now or hereafter liable for the payment hereof, expressly waives
presentment for payment, demand, notice of nonpayment, notice of protest and
protest of this Note, and diligence in collection, bringing suit or

                            INTER-CREDITOR AGREEMENT

     THIS INTER-CREDITOR AGREEMENT (the "Agreement"), dated as of  January 30,
1997, between SUN PHARMA GLOBAL, INC., a company registered in the British
Virgin Islands with administrative offices at P.O. Box 12850 Dubai, U.A.E.
("Sun"), JAY F. JOLIAT, INDIVIDUALLY AND AS TRUSTEE OF THE JAY F. JOLIAT
QUALIFIED TERMINABLE INTEREST MARITAL TRUST, U/A/D 4/8/82, whose address is
1411 North Woodward, Suite 300, Birmingham, Michigan 48009 ("Joliat") and DAVID
A. HAGELSTEIN, INDIVIDUALLY AND AS TRUSTEE OF THE DAVID HAGELSTEIN TRUST, U/A/D
10-27-93, whose address is 1411 North Woodward, Suite 313, Birmingham, Michigan
48009 ("Hagelstein")(collectively, the "Creditors") and CARACO PHARMACEUTICAL
LABORATORIES, LTD., a Michigan corporation, whose address is 1150 Elijah McCoy
Dr., Detroit, Michigan 48202 (the "Debtor").

                               R E C I T A L S :

     Sun has loaned Debtor (the "Sun Loan") the amount of $350,000 pursuant to
that certain Secured Promissory Note dated December 23, 1996,  and in
connection therewith Debtor and Sun have entered into that certain Security
Agreement dated December 23, 1996, as to which a UCC Financing Statement was
filed with the Secretary of State of Michigan on January 8, 1997 (the "Sun Loan
Documents");

     Creditors and Debtor entered into a Subordination Agreement dated December
23, 1996 (the "Subordination Agreement"), pursuant to which Joliat and
Hagelstein subordinated certain prior indebtedness and related security
interests in certain collateral to Sun.

     Debtor had requested a loan of $200,000 from each of the Creditors for
working capital purposes.  However, Sun has indicated that it is unable to
provide such a loan.  As a result, Hagelstein and Joliat shall loan Debtor an
aggregate of $200,000 and $400,000, respectively (the "Hagelstein Loan" and the
"Joliat Loan," respectively) pursuant to Secured Promissory Notes, Security
Agreements and UCC Financing Statements of even date herewith (the "Hagelstein
Loan Documents" and the Joliat Loan Documents," respectively), subject to the
condition (the "Condition") that Sun agree that (i) the Sun Loan be paid back
at the same time and on a proportionate basis to the Hagelstein Loan and the
Joliat Loan and (ii) the security interest of Sun in the collateral underlying
the Sun Loan have equal priority to the security interests of Hagelstein and
Joliat in the Hagelstein Loan and the Joliat Loan.

     Sun, in order to accommodate Hagelstein and Joliat and assist Debtor in
raising needed financing, and acknowledging the personal benefit to Sun of the
Hagelstein Loan and the Joliat Loan, desires to satisfy the Condition and
thereby permit Hagelstein and Joliat to make the Hagelstein Loan and the Joliat
Loan, respectively.

     NOW, THEREFORE, in consideration of Hagelstein's loan to Debtor as set
forth in the  Hagelstein Loan Documents and Joliat's loan to Debtor as set
forth in the Joliat Loan Documents, 






<PAGE>   2


and in consideration of the mutual covenants and agreements contained in this
Agreement, the parties hereto agree     as follows:

     1. PRE-DEFAULT NOTE REPAYMENTS.  Principal payments by Debtor under the Sun
Loan, the Hagelstein Loan and the Joliat Loan, shall be made proportionately
until each of the loans has been paid in full, as follows:


                         Sun            36.84%          (350/950)
                         Joliat         42.11%          (400/950)
                         Hagelstein     21.05%          (200/950)


Further, if any Creditor receives payments from Debtor with respect to the Sun
Loan, the Hagelstein Loan, and the Joliat Loan which are not in the proportions
noted above, such Creditor shall be liable and accountable to the other
Creditors for their proportionate share, shall be deemed to have received such
payment in trust for the use and benefit of the other Creditors, shall not
commingle the same with any other funds and shall pay over and deliver such
payment to the other Creditors immediately to be applied upon the indebtedness
of Debtor to such other Creditors pursuant to the applicable loans.

     2. DEFAULTS.  If an event of default occurs under the terms and conditions
of either the Sun Loan, the Hagelstein Loan or the Joliat Loan, it will be
deemed a default under the Sun Loan, the Hagelstein Loan and the Joliat Loan.

     3. EQUAL PRIORITY IN COLLATERAL.  Creditors agree that with respect to the
collateral securing the Sun Loan, the Hagelstein Loan and the Joliat Loan,
notwithstanding that some of the collateral securing the Hagelstein Loan and
the Joliat Loan is the same collateral which is the subject of the
Subordination Agreement, and despite Sun having perfected its security interest
in the collateral pursuant to the Sun Loan earlier than Hagelstein and Joliat
pursuant to the Hagelstein Loan and Joliat Loan, respectively, the security
interests of Sun, Joliat and Hagelstein in the collateral securing the Sun
Loan, the Hagelstein Loan and the Joliat Loan, respectively, will be treated
pari passu to each other and each Creditor will have an equal priority in such
collateral.  However, with respect to the division of any proceeds from the
disposition of any such collateral, the proceeds will be divided
proportionately in the percentages set forth in Paragraph 1 above.

     4. FUTURE ACTION.  Creditors further covenant and agree that they shall
take whatever steps are necessary, from time to time, to evidence and
acknowledge and/or confirm and/or consent to the equal priority, perfection and
delivery of their security interests in the collateral underlying their
respective Sun Loan, Hagelstein Loan and Joliat Loan, including but not by way
of limitation, amendment to their respective financing statements filed with
respect to such collateral.

                                      2

<PAGE>   3


     5. NO DIVIDENDS.  Debtor agrees that as long as Debtor is indebted to
Creditors under the Sun Loan, Hagelstein Loan and Joliat Loan, no dividends or
distributions, whether in cash, stock or other property shall be declared or
paid to any shareholder.

     6. DURATION AND TERMINATION.  This Agreement shall terminate only upon
payment or performance in full of all of the obligations under the Sun Loan,
Hagelstein Loan and Joliat Loan.  Neither the death nor the bankruptcy of any
Creditor shall effect a termination hereof.

     7. ASSIGNMENT.  Creditors further covenant and agree that until the
payment in full of any and all of the indebtedness of Debtor to Creditors
pursuant to the Sun Loan, the Hagelstein Loan and the Joliat Loan, they shall
not assign their respective Sun Loan Documents, Hagelstein Loan Documents or
Joliat Loan Documents or any of their respective interest in such loan
documents to any other person ("Transferee") without the written consent of the
other Creditors, which will not be unreasonably withheld, and the written
agreement of such Transferee to be bound by all of the terms and conditions of
this Agreement.

     8. NOTICES.  All notices, requests, demand and other communications
required or permitted under this Agreement or by law shall be in writing and
shall be deemed to have been duly given, made and received only when sent by
facsimile transmission (receipt confirmed) or reputable overnight delivery
service (receipt confirmed), when delivered against receipt, or when deposited
in the United States mails, certified mail, return receipt requested, postage
prepaid, addressed as set forth above.

     Any addressee may alter the address to which communications are to be sent
by giving notice of such change of address in conformity with the provisions of
this section for the giving of notice.

     9. ENTIRE AGREEMENT.  This Agreement constitutes and expresses the entire
understanding between the parties hereto with respect to the subject matter
hereof, and supersedes all prior and contemporaneous agreements and
understandings, inducements or conditions, whether express or implied, oral or
written.  Neither this Agreement nor any portion or provision hereof may be
changed, waived or amended orally or in any manner other than by an agreement
in writing signed by Debtor and the Creditors.

     10. SUCCESSORS AND ASSIGNS.  This Agreement shall inure to and shall be
binding upon Debtor and each Creditor and their respective heirs, executors,
administrators, personal representatives, successors and permitted assigns.

     11. GOVERNING LAW.  The validity, construction and enforcement of this
Agreement shall be governed by the laws of the State of Michigan, without
regard to its conflict of laws and rules.



                                      3

     12. SEVERABILITY.  The provisions of this Agreement are independent of and
separable from each other.  If any provision hereof shall for any reason be
held invalid or unenforceable, it is the intent of the parties that such
invalidity or unenforceability shall not affect the validity or enforceability
of any other provision hereof, and that this Agreement shall be construed as if
such invalid or unenforceable provision had never been contained herein.

     13. COUNTERPARTS.  This Agreement may be executed in multiple
counterparts, each of which shall be deemed an original and all of which shall
constitute one agreement.  The signature of any party to any counterpart shall
be deemed to be a signature to, and may be appended to, any other counterpart.
This Agreement is binding on each party upon execution thereof.

     IN WITNESS WHEREOF, the parties hereto have caused this Agreement to be
signed, sealed and delivered as of the date first above written.

Dollars, with interest as therein provided, executed and delivered by Debtor to
Secured Party (the "Notes"), as the same may be modified, renewed, extended,
amended or replaced from time to time, and shall pay all amounts and perform all
obligations required under or pursuant to this Agreement and all other documents

     3.   ACCELERATION CLAUSE.  Upon the occurrence of any Default (as defined
pursuant to Section 9 hereof), all of the Indebtedness of Debtor, whether due

time, replace and repair all parts of the Collateral as may be broken, worn,

damage by casualty, theft and such other perils with insurers and coverages
reasonably acceptable to Secured Party.

     8.   DEBTOR'S WARRANTIES AND REPRESENTATIONS.  Debtor warrants, represents
and covenants that:

          A.   The Collateral is or will be owned by Debtor and except with
               respect to the collateral securing the Sun Loan and Hagelstein
               Loan as defined in that certain Inter-Creditor Agreement of even
               date herewith, the Collateral is not subject to any security
               interests, liens or encumbrances, charges, restrictions or claims
               except as created by this Agreement, and Debtor will defend the
               Collateral against the claims and demands of all persons;

                                      3
<PAGE>   4



          B.   Debtor will execute, and will pay all costs of filing of, any
               financing, continuation or termination statement with respect to
               the security interest created by this Agreement deemed necessary
               or desirable by the Secured Party;


          C.   Debtor shall from time to time, at the expense of Debtor, execute
               and deliver all further instruments and documents, and take all
               further actions, that the Secured Party may reasonably deem
               necessary or desirable, in order to perfect and protect any
               security interest granted or purported to be granted hereby or to
               enable the Secured Party to exercise and enforce its rights and
               remedies hereunder with respect to any Collateral.

          D.   Debtor hereby authorizes the Secured Party to file one or more
               financing or continuation statements, and amendments thereto,
               relative to all or any part of the Collateral, with or without
               Debtor's signature thereon.

          E.   Debtor was incorporated under the name J-Mac Domestic, Inc.,
               changed its name to Caraco, Inc. until changing its name to its
               current name, and Debtor's chief executive office and sole place
               of business is located at 1150 Elijah McCoy Drive, Detroit,
               Michigan 48202.

          F.   Debtor is a corporation duly organized under the laws of
               Michigan, validly existing and in good standing and has full
               corporate power to own, operate and lease its properties and to
               carry on its business as now conducted. Debtor is qualified to do
               business in all jurisdictions where the nature of its activities
               would make such qualification necessary and the failure to so
               qualify would have a material and adverse affect on the Debtor.

          G.   Debtor has all power, statutory and otherwise, to execute and
               deliver this Security Agreement, the Notes and the Inter-Creditor
               Agreement, and the execution hereof and thereof, and Debtor's
               performance of its obligations hereunder and thereunder, have
               been approved by all appropriate corporate action.  Such
               agreements and documents constitute the legal, valid and binding
               obligation of Debtor, enforceable against such Debtor in
               accordance with its terms.

          H.   The equipment listed on Schedule A hereto is not subject to the
               lien of the Economic Development Corporation of the City of 




                                      4

<PAGE>   5

               Detroit and Debtor reasonably believes the Equipment has a fair
               market value of not less than $1.5 million.

I.   Debtor shall not move the Collateral or change Debtor's name, identity or
     corporate structure unless it has received Secured Party's prior written
     consent thereto and has taken all action necessary or reasonably requested
     by the Secured Party to amend any financing statement or continuation
     statement filed with respect to the Collateral in connection therewith.

          J.   The execution, delivery and performance of this Agreement and the
               other Loan Documents by Debtor and its performance of its
               obligations hereunder and thereunder does not conflict with or
               result in any violation of or constitute a breach or default
               under (i) any term of the Articles of Incorporation or Bylaws of
               Debtor, (ii) any indenture, agreement instrument, order, judgment
               or decree to which Debtor is a party, bound or subject or to
               which any of the assets or business of Debtor are subject, (iii)
               any law, statute or regulation of any governmental or regulatory
               body.

          K.   No approval or consent of the execution, delivery and performance
               by the Debtor of this Agreement, the Notes, and the other Loan
               Documents is required by law or by the Debtor's existing Articles
               of Incorporation or Bylaws or by any contract, indenture,
               agreement, instrument, order, judgment or decree to which the
               Debtor is a party or otherwise bound or to which any of its
               property or business is subject, or by any indebtedness of the
               Debtor.

          L.   There are no actions, proceedings or investigations pending or,
               to the knowledge of the Debtor, threatened against the Debtor
               before any court, administrative agency or other governmental or
               regulatory authority.  Neither the Debtor nor its property and
               assets is subject to any judicial or administrative order,
               judgment or decree which could have a material adverse effect on
               the Debtor, its business, properties, condition (financial or
               otherwise) or prospects.  The Debtor has not violated any
               federal, state or local laws, regulations or orders.

     9.   DEFAULT.  The following shall constitute defaults (each a "Default")
under this Agreement:

          A.   The occurrence of any breach of warranty or other
               misrepresentation, omission or misstatement in connection with

              Debtor;

         B.   Any default in the payment of any portion of the
              Indebtedness when due in accordance with the terms of the Notes,

              Debtor shall indicate approval of, consent to, or acquiescence to
              such appointment, or (ii) such custodian, trustee, or receiver
              shall not be discharged within thirty (30) days; or Debtor shall
              voluntarily seek protection from creditors under any applicable
              state or federal bankruptcy, liquidation or dissolution,
              insolvency, or debt reorganization laws; or any of Debtor's
              creditors shall institute any proceeding against Borrower under

    10.  REMEDIES.   In the event of the occurrence of any default, Secured 
Party may exercise its rights under law, including by way of
enforcement under the Uniform Commercial Code in effect in the State of
Michigan as in effect from time to time.  Secured Party may enter Debtor's
premises without legal process or any obligation to pay rent and remove the
Collateral or require the Debtor to assemble the Collateral and make it
available to Secured Party at a place within or outside the State of Michigan
designated by Secured Party.  If it so elects, Secured Party may and is hereby
empowered, without legal process, to enter any premises where the Collateral
may be kept and take exclusive possession of it on those premises with or
without a custodian.  Secured Party may thereafter sell the Collateral at one
or more public or private sales, on or away from Debtor's business premises. 
Unless the Collateral is perishable, threatens to decline speedily in value or
is of a type customarily sold on a recognized market, Secured Party shall give
Debtor reasonable notice of the time and place of any public sale thereof, or
of the time after which any private sale or any other intended disposition
thereof is to be made.  The requirement of reasonable notice shall be met if
notice is mailed to Debtor, postage prepaid, by first class certified mail,
return receipt requested, at least five (5) days prior to the date of the
proposed sale or disposition.  At any such sale, Secured Party may in its
absolute discretion sell and dispose of all the right, title, and interest of
Debtor in and to any of the Collateral. Any such sale may be for cash or for
credit, and Secured Party may be the purchaser.  Secured Party shall have the
right to (i) demand payments of the Accounts, (ii) enforce payment of the
Accounts by legal proceedings or otherwise, (iii) exercise all of Debtor's
rights and remedies with respect to the collection of the Accounts, (iv)
settle, adjust or compromise any legal proceedings brought to collect the
Accounts, (v) if permitted by law, sell or assign the Accounts upon such terms,
for such amounts and at such time or times as the Secured Party deems
advisable, (vi) discharge and release the Accounts, (vii) prepare, file and
sign Debtor's name on any proof of claim in bankruptcy or similar document
against any account debtor, (viii) prepare, file and sign any Debtor's name on
any notice of lien, assignment or satisfaction of lien or similar document in
connection with the Accounts, (ix) do all acts and things necessary in the
Secured Party's sole discretion, to fulfill Debtor's obligations under this
Security Agreement, (x) endorse the name of Debtor upon any Chattel Paper,
Document, Instrument, invoice, freight bill, bill of lading or similar document
or agreement relating to the Collateral, (xi) use Debtor's stationery and sign
the name of Debtor to verifications of the Accounts and notice thereof to
Account debtors, and (xii) use the information recorded on or contained in any
data processing equipment and computer hardware, software and source codes
relating to the Collateral to which Debtor has access.  Out of the monies
arising from the sale and/or collection of the Collateral, Secured Party shall
retain any and all sums then owing to Secured Party, including all additional
advances and debts, and all costs, fees, charges and expenses in connection
therewith, with interest, including reasonable attorneys fees, disbursements,
premiums on bonds, custodian's fees, fees of public officers, auctioneer's
fees, plus advertising and labor, disbursements for use and occupancy of
premises and any and all other disbursements made by Secured Party in
connection with the taking, maintaining, storage and disposing of the
Collateral, tendering the excess (if any) to Debtor or its successors or
assigns.  If for any reason the Collateral shall fail to satisfy all of the
foregoing items, Debtor shall pay to Secured Party the resulting deficiency
upon demand.  Secured Party's remedies shall be cumulative and non-exclusive to
the fullest extent permitted by law.

    11.  DISCRETIONARY RIGHTS.  Exercise of or omission to exercise any right of
the Secured Party shall not affect any other subsequent right of the Secured
Party to exercise the same and the waiver of any default by the Secured Party
shall not be deemed a waiver of any subsequent Default.

    12.  SEVERABILITY.   If any provision of this Agreement shall for any reason
be held to be invalid or unenforceable, that invalidity or unenforceability
shall not affect any other provision hereof, and this Agreement shall be

herein.

in writing as provided by this paragraph.  Notice so directed and posted shall
be effective upon receipt.

    14.  GOVERNING LAW.  This Agreement shall be governed by and interpreted in
accordance with the laws of the State of Michigan.

    15.  COUNTERPARTS.  This Agreement may be executed in multiple

LITIGATION IN ANY COURT WITH RESPECT TO, IN CONNECTION WITH, OR ARISING OUT OF
THIS AGREEMENT OR ANY

Dollars, together with interest at 10.0% per annum payable in cash or shares of
Common Stock of Borrower as determined in the sole discretion of Borrower.
This Secured Promissory Note (the "Note") shall mature, and all principal
outstanding hereunder, together with all accrued and unpaid interest thereon

Lender does not intend to proceed with and/or continue negotiations regarding
the Proposed Transaction, unless such failure to proceed constitutes a breach
of any legal obligation which Sun Pharmaceutical may hereafter incur in writing
or (B) in any event, upon the occurrence of a Default as defined pursuant to

pay all amounts and perform all obligations required under or pursuant to this
Agreement and all other documents and/or agreements delivered to Secured Party
in connection with the Notes (the "Loan Documents"), such obligations of
payment and performance being hereinafter collectively referred to as the
"Indebtedness".

     3. ACCELERATION CLAUSE.  Upon the occurrence of any Default (as defined
pursuant to Section 9 hereof), all of the Indebtedness of Debtor, whether due
or not, shall become immediately due and payable in accordance with the terms
of the Notes and the other Loan Documents.

     4. USE OF COLLATERAL.  The Collateral shall be used exclusively in
connection with the conduct of Debtor's present business, unless Secured Party
gives its written consent to another use.  Secured Party shall have the right
to inspect the Collateral at any time, to inspect Debtor's books and records
with respect thereto and to make inquiry of account and contract debtors in
connection therewith, all at any time.

     5. REMOVAL.  The Collateral shall be kept at Debtor's business premises,
and shall not be removed therefrom without the written consent of Secured
Party.  Removal of any of the Collateral by Debtor, or its agents, servants or
employees, shall be deemed a willful taking, an unlawful conversion and a
default under this Agreement.  Use of the Collateral and sale of the Inventory
in the regular and ordinary course of Debtor's business shall not constitute a
prohibited removal of the Collateral for the purpose of this Agreement.

     6. REPAIRS AND TAXES.  Debtor shall at its own expense, from time to time,
replace and repair all parts of the Collateral as may be broken, worn, damaged
or otherwise in need of repair, and shall keep the Collateral in every respect
in good working order and repair.  Debtor shall pay all taxes charged against,
assessed or imposed upon any of the Collateral.

     7. INSURANCE.  Debtor shall keep the Collateral insured against loss and
damage by casualty, theft and such other perils with insurers and coverages
reasonably acceptable to Secured Party.

     8. DEBTOR'S WARRANTIES AND REPRESENTATIONS.  Debtor warrants, represents
and covenants that:

                    A.    The Collateral is or will be owned by Debtor and 
                         except with respect to the collateral securing the 
                         Sun Loan and Joliat Loan as defined in that certain 
                         Inter-Creditor Agreement of even date herewith, the 
                         Collateral is not subject to any security interests, 
                         liens or encumbrances, charges, restrictions or 
                         claims except as created by this Agreement, and 
                         Debtor will defend the Collateral against the claims 
                         and demands of all persons;

                    B.   Debtor will execute, and will pay all costs of
                         filing of, any financing, continuation or termination
                         statement with respect to the security interest
                         created by this Agreement deemed necessary or
                         desirable by the Secured Party;

                    C.   Debtor shall from time to time, at the expense
                         of Debtor, execute and deliver all further instruments
                         and documents, and take all further actions, that the
                         Secured Party may reasonably deem necessary or
                         desirable, in order to perfect and protect any
                         security interest granted or purported to be granted
                         hereby or to enable the Secured Party to exercise and
                         enforce its rights and remedies hereunder with respect
                         to any Collateral.

                    D.   Debtor hereby authorizes the Secured Party to
                         file one or more financing or continuation statements,
                         and amendments thereto, relative to all or any part of
                         the Collateral, with or without Debtor's signature
                         thereon.

                    E.   Debtor was incorporated under the name J-Mac
                         Domestic, Inc., changed its name to Caraco, Inc. until
                         changing its name to its current name, and Debtor's
                         chief executive office and sole place of business is
                         located at 1150 Elijah McCoy Drive, Detroit, Michigan
                         48202.

                    F.   Debtor is a corporation duly organized under
                         the laws of Michigan, validly existing and in good
                         standing and has full corporate power to own, operate
                         and lease its properties and to carry on its business
                         as now conducted. Debtor is qualified to do business
                         in all jurisdictions where the nature of its
                         activities would make such qualification necessary and
                         the failure to so qualify would have a material and
                         adverse affect on the Debtor.

                    G.   Debtor has all power, statutory and otherwise,
                         to execute and deliver this Security Agreement, the
                         Notes and the Inter-Creditor Agreement, and the
                         execution hereof and thereof, and Debtor's performance
                         of its obligations hereunder and thereunder, have been
                         approved by all appropriate corporate action.  Such
                         agreements and documents constitute the legal, valid
                         and binding obligation of Debtor, enforceable against
                         such Debtor in accordance with its terms.

                    H.   The equipment listed on Schedule A hereto is
                         not subject to the lien of the Economic Development
                         Corporation of the City of 



                                      4

                         Detroit and Debtor reasonably believes the
                         Equipment has a fair market value of not less than
                         $1.5 million.

                    I.   Debtor shall not move the Collateral or change
                         Debtor's name, identity or corporate structure unless
                         it has received Secured Party's prior written consent
                         thereto and has taken all action necessary or
                         reasonably requested by the Secured Party to amend any
                         financing statement or continuation statement filed
                         with respect to the Collateral in connection
                         therewith.

                    J.   The execution, delivery and performance of this
                         Agreement and the other Loan Documents by Debtor and
                         its performance of its obligations hereunder and
                         thereunder does not conflict with or result in any
                         violation of or constitute a breach or default under
                         (i) any term of the Articles of Incorporation or
                         Bylaws of Debtor, (ii) any indenture, agreement
                         instrument, order, judgment or decree to which Debtor
                         is a party, bound or subject or to which any of the
                         assets or business of Debtor are subject, (iii) any
                         law, statute or regulation of any governmental or
                         regulatory body.

                    K.   No approval or consent of the execution,
                         delivery and performance by the Debtor of this
                         Agreement, the Note, and the other Loan Documents is
                         required by law or by the Debtor's existing Articles
                         of Incorporation or Bylaws or by any contract,
                         indenture, agreement, instrument, order, judgment or
                         decree to which the Debtor is a party or otherwise
                         bound or to which any of its property or business is
                         subject, or by any indebtedness of the Debtor.

                    L.   There are no actions, proceedings or investigations 
                         pending or, to the knowledge of the Debtor, 
                         threatened against the Debtor before any
                         court, administrative agency or other governmental or
                         regulatory authority.  Neither the Debtor nor its
                         property and assets is subject to any judicial or
                         administrative order, judgment or decree which could
                         have a material adverse effect on the Debtor, its
                         business, properties, condition (financial or
                         otherwise) or prospects.  The Debtor has not violated
                         any federal, state or local laws, regulations or
                         orders.

           A.    The occurrence of any breach of warranty or other 
                 misrepresentation, omission or misstatement in connection

                         representations or warranties under this Agreement,

                         not cured within 15 days after notice thereof from

                    B.   Any default in the payment of any portion of the

                         jurisdiction of a custodian, trustee or receiver to

                         the assets of Debtor pursuant to any involuntary
                         proceeding and either (i) Debtor shall indicate

        10. REMEDIES.   In the event of the occurrence of any default, Secured
Party may exercise its rights under law, including by way of enforcement under
the Uniform Commercial Code in effect in the State of Michigan as in effect
from time to time.  Secured Party may enter Debtor's premises without legal
process or any obligation to pay rent and remove the Collateral or require the
Debtor to assemble the Collateral and make it available to Secured Party at a
place within or outside the State of Michigan designated by Secured Party.  If
it so elects, Secured Party may and is hereby empowered, without legal process,
to enter any premises where the Collateral may be kept and take exclusive
possession of it on those premises with or without a custodian.  Secured Party
may thereafter sell the Collateral at one or more public or private sales, on
or away from Debtor's business premises.  Unless the Collateral is perishable,
threatens to decline speedily in value or is of a type customarily sold on a
recognized market, Secured Party shall give Debtor reasonable notice of the
time and place of any public sale thereof, or of the time after which any
private sale or any other intended disposition thereof is to be made.  The
requirement of reasonable notice shall be met if notice is mailed to Debtor,
postage prepaid, by first class certified mail, return receipt requested, at
least five (5) days prior to the date of the proposed sale or disposition.  At
any such sale, Secured Party may in its absolute discretion sell and dispose of
all the right, title, and interest of Debtor in and to any of the Collateral. 
Any such sale may be for cash or for credit, and Secured Party may be the
purchaser.  Secured Party shall have the right to (i) demand payments of the
Accounts, (ii) enforce payment of the Accounts by legal proceedings or
otherwise, (iii) exercise all of Debtor's rights and remedies with respect to
the collection of the Accounts, (iv) settle, adjust or compromise any legal
proceedings brought to collect the Accounts, (v) if permitted by law, sell or
assign the Accounts upon such terms, for such amounts and at such time or times
as the Secured Party deems advisable, (vi) discharge and release the Accounts,
(vii) prepare, file and sign Debtor's name on any proof of claim in bankruptcy
or similar document against any account debtor, (viii) prepare, file and sign
any Debtor's name on any notice of lien, assignment or satisfaction of lien or
similar document in connection with the Accounts, (ix) do all acts and things
necessary in the Secured Party's sole discretion, to fulfill Debtor's
obligations under this Security Agreement, (x) endorse the name of Debtor upon
any Chattel Paper, Document, Instrument, invoice, freight bill, bill of lading
or similar document or agreement relating to the Collateral, (xi) use Debtor's
stationery and sign the name of Debtor to verifications of the Accounts and
notice thereof to Account debtors, and (xii) use the information recorded on or
contained in any data processing equipment and computer hardware, software and
source codes relating to the Collateral to which Debtor has access.  Out of the
monies arising from the sale and/or collection of the Collateral, Secured Party
shall retain any and all sums then owing to Secured Party, including all
additional advances and debts, and all costs, fees, charges and expenses in
connection therewith, with interest, including reasonable attorneys fees,
disbursements, premiums on bonds, custodian's fees, fees of public officers,
auctioneer's fees, plus advertising and labor, disbursements for use and
occupancy of premises and any and all other disbursements made by Secured Party
in connection with the taking, maintaining, storage and disposing of the
Collateral, tendering the excess (if any) to Debtor or its successors or
assigns.  If for any reason the Collateral shall fail to satisfy all of the
foregoing items, Debtor shall pay to Secured Party the resulting deficiency
upon demand.  Secured Party's remedies shall be cumulative and non-exclusive to
the fullest extent permitted by law.

     11. DISCRETIONARY RIGHTS.  Exercise of or omission to exercise any right of
the Secured Party shall not affect any other subsequent right of the Secured
Party to exercise the same and the waiver of any default by the Secured Party
shall not be deemed a waiver of any subsequent Default.

     12. SEVERABILITY.   If any provision of this Agreement shall for any reason
be held to be invalid or unenforceable, that invalidity or unenforceability
shall not affect any other provision hereof, and this Agreement shall be
construed as if the invalid or unenforceable provision had never been contained
herein.

     13. NOTICES. All notices to the parties under this Agreement shall be
sufficient if mailed by certified mail, return receipt requested with

in writing as provided by this paragraph.  Notice so directed and posted shall
be effective upon receipt.

hereof shall inure to, the parties hereto and their respective successors and
assigns.   Debtor's obligations and rights hereunder shall not be assigned

     18. INDEMNITY.  Debtor agrees to indemnify the Secured Party from and
against any and all claims, losses and liabilities in connection with or
arising out of this Security Agreement, the Inter-Creditor Agreement or the
Notes and any actions taken hereunder or thereunder, except where due to
Secured Party's gross negligence or wilful misconduct.

                    CARACO PHARMACEUTICAL LABORATORIES, LTD.


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


     Management's Discussion and Analysis of Operations is designed to provide
shareholders with a comprehensive overview of the results from operations and
financial position that could not otherwise be obtained from an examination of
the financial statements alone.  This discussion should be read in conjunction 
with the financial statements and related footnotes.

General

     Due to intense competition there is a price and profit margin erosion
trend currently being experienced in the generic drug industry in the United
States.  This competition affects the pricing and profit margins on new product
introductions and on current products.  A greater number of generic
manufacturers entering the market upon patent expiration of a drug limits the
duration of potential higher profit margins on new product introductions.

     Net sales for the years ended December 31, 1996 and 1995 were $1,273,903
and $4,048,096, respectively.  The 1996 decrease of 69% in sales is directly
attributable to market conditions including negative press reports on calcium
channel blockers which lowered the demand for Nifedipine and forced the
Corporation to lower the price of Nifedipine, to remain competitive.  This
significantly lowered Nifedipine sales revenue in 1996. It is anticipated that
the current depressed level of sales will continue for the indefinite future.

     The Corporation also anticipates increased sales volume from three (3)
ANDAs currently in various stages of the FDA approval process.  The first of
these ANDAs is expected to contribute sales in the second quarter of 1997.
The Corporation continues to search for strategic alternatives to improve its
financial condition and product line.

COST OF SALES

     Cost of sales for the years ended December 31, 1996 and 1995 were
$1,642,237 or 128.9% of sales and $3,063,648 or 75.7% of sales, respectively.
The increased percentage in cost of sales was a direct result of significantly
lower sales and manufacturing volumes due to the Corporation's inability to
purchase raw materials and bulk product from its suppliers leaving the
Corporation unable to maintain adequate levels of 

                                   - 19 -


<PAGE>   2

customer service.   As a result, sales were not adequate to absorb the
Corporation's fixed production costs.
        
GENERAL AND ADMINISTRATIVE

     Selling, general and administrative expenses for the years ended December
31, 1996 and 1995 were $1,915,908 and $2,167,311, respectively.  The decrease
of 12% in 1996 is directly related to the Corporation's cost containment
program implemented in 1995 in response to the Corporation's losses and
industry trends.  The Corporation continues to implement measures to further
reduce costs and improve operating efficiencies.  In addition a wage and hiring
freeze was continued during the current year which resulted in a 28% reduction
in the Corporation's employees.

RESEARCH AND DEVELOPMENT

     Product development expenses for the years ended December 31, 1996 and
1995 were $2,222,220 and $2,236,414, respectively, demonstrating Caraco's
continued commitment to new product development as a means to increase and
diversify its product offering despite the Corporation's current financial
condition.  The Corporation plans to continue to expand product development
activities as its resources permit as it believes such efforts are vital to
expanding the Corporation's product line and generating future products.  In
late 1996, the Corporation was notified of an ANDA approval for a product
submitted to the FDA.  This product is now in the early stages of market
development.  While there can be no guarantee the Corporation anticipates FDA
approval of an additional two products in 1997.

RESULTS OF OPERATIONS

     Operating losses for the years ended December 31, 1996 and 1995 were
$4,506,464 and $3,419,277, respectively.  The increase in operating loss is
directly related to the significant decrease in net sales which were inadequate
to absorb the fixed costs of the Corporation's operational expenses.

     A number of uncertainties exist that may influence the Corporation's
future operating results, including general economic conditions, changes in
conditions affecting the pharmaceutical industry primarily related to generic
drug competition, the Corporation's success in developing and market acceptance
of new products, manufacturing performance, availability and price fluctuations
of raw materials, FDA regulations and other factors.

NET INTEREST EXPENSE

     Interest expense, which is incurred primarily in connection with the
Corporation's mortgage obligation to the Economic Development Corporation of
Detroit, was $680,767 and $715,193 for the years ended December 31, 1996 and
1995, respectively.  The decrease in interest expense in 1996 relates to a
shorter holding period in 1996 than in 1995 of short term loans used to finance
the Corporation's short term cash needs.

OTHER INCOME/EXPENSE

     Net other income/expense for years ended December 31, 1996 and 1995
were a loss of $317,974 and income of $35,451, respectively.  The net expense
reported in 1996 was a result of the Corporation's disposal and write down of
certain equipment totaling $111,183, and the recognition of a $194,750 loss due
to the decline in value of the marketable securities owned by the Corporation. 
The gain in 1995 was a result of the sale of an obsolete tablet press.

LIQUIDITY AND CAPITAL RESOURCES

     At December 31, 1996 the Corporation's working capital deficit was
$11,530,591 compared with a working capital deficit of $399,160 at December 31,
1995.  The decrease in working capital in 1996 is directly attributable to the
Corporation's continued losses from operations and the reclassification of the
entire EDC Loan as current during 1996 as a result of default.  See Note 4 of 
Notes to Financial Statements for the scheduled principal amounts due under the
EDC Loan.

     Management estimates that, at its currently planned and anticipated level
of operations, the Corporation will experience continued operating losses in
1997, and accordingly, will require approximately $7,500,000 of additional
funds to execute its business expansion plan on a going forward basis and fund
continuing operations.

     The Corporation has no material commitments for capital expenditures.

     The Corporation is currently in default on its Loan from the EDC, which
includes principal in arrearage, interest, and personal and real property
taxes.  The Corporation is negotiating with the EDC to modify the terms of the
Loan and bring it current.  See Item 1 Current Status of Corporation.

     On July 11, 1996 the Corporation and an Indian specialty company, Sun
Pharmaceutical Industries Ltd. ("Sun Pharma") 



                                   - 21 -

<PAGE>   4



announced that they had signed two non-binding letters of intent pursuant to
which Sun Pharma would make an initial investment in Caraco common stock and    
sell it certain rights for a number of generic pharmaceutical products.  As
revised in the most recent proposal, it is contemplated that (a) Sun Pharma
will invest $7,500,000 to be received by the Corporation over a period of one
year in four installments, (b) the number of products to be sold to the
Corporation by Sun Pharma is 25 over a period of five years in exchange for
544,000 shares of Caraco common stock to be issued for each product and (c) two
current Caraco shareholder directors will each contribute to the Corporation up
to $500,000 in cash or common stock of Caraco, not to exceed 250,000 shares.
The price will be determined at the midpoint of the bid and ask price at the
closing on the day of contribution.  This transaction is subject to certain
conditions, including completion of Sun Pharma's due diligence, clearance of
various agencies in the Indian government, approval of any EDC modification of
debt to the Corporation, and negotiation and execution of
definitive documents.  Negotiations are ongoing at this time.

     As of December 31, 1996 net operating loss carryforwards of approximately
21,000,000 are available to offset future federal taxable income, if any,
through 2011.  The Corporation's ability to utilize the NOL carryforwards may
be limited due to an ownership change.

     If the completion of the agreement with Sun Pharma does not occur and the
Corporation does not receive the anticipated equity capital, it is expected
that the Corporation would immediately commence bankruptcy proceedings pursuant
to Chapter 7 of the Federal Bankruptcy Code of 1978, as amended.

     There is no assurance that the foregoing funds will be made available to
the Corporation timely or on financially satisfactory terms; or that any of the
Corporation's ANDAs will be approved by the FDA within time parameters 
anticipated by management or at all, or that the Corporation will be able to
manufacture in commercial quantities and sell profitably any product resulting
from FDA approval of an ANDA filed by the Corporation.  To the extent that
capital requirements should exceed available capital, the Corporation will be
required to reduce its research and development activity, reduce personnel and
delay capital expenditures while continuing to seek alternative sources of
financing for its business. There is no assurance that alternative sources of
financing will be available.

                          INDEPENDENT AUDITORS' REPORT



Stockholders and Board of Directors
CARACO PHARMACEUTICAL LABORATORIES, LTD.
Detroit, Michigan


We have audited the accompanying balance sheet of Caraco Pharmaceutical
Laboratories, Ltd. (a Michigan corporation) as of December 31, 1996, and the
related statements of operations, stockholders' deficit and cash flows for
the years ended December 31, 1996 and 1995.  These financial statements are
the responsibility of the Corporation's management.  Our responsibility is
to express an opinion on these financial statements based on our audits.

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

In our opinion, the financial statements referred to above present fairly,
in all material respects, the financial position of Caraco Pharmaceutical
Laboratories, Ltd. as of December 31, 1996 and the results of its operations
and its cash flows for the years ended December 31, 1996 and 1995 in
conformity with generally accepted accounting principles.

The accompanying financial statements have been prepared assuming the
Corporation will continue as a going concern.  As described in Note 1 to the
financial statements, conditions exist that raise substantial doubt about
the Corporation's ability to continue as a going concern.  Management's
plans in regard to these matters are also described in Note 1.  The
financial statements do not include any adjustments that might result from
the outcome of this uncertainty.

                   CARACO PHARMACEUTICAL LABORATORIES, LTD.

                        NOTES TO FINANCIAL STATEMENTS

                FOR THE YEARS ENDED DECEMBER 31, 1996 AND 1995


1.   ORGANIZATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

     Organization and Basis of Presentation

     Caraco Pharmaceutical Laboratories, Ltd. ("Caraco" or the
     "Corporation") was incorporated on February 22, 1984, and has generated
     limited revenue from planned principal operations.  The Corporation,
     since inception, has primarily been involved in planning, obtaining
     financing, constructing a permanent facility, acquiring and validating
     production equipment, hiring and training employees and beginning the
     development of product lines.  The Corporation was established to
     develop, manufacture and market generic prescription and
     over-the-counter pharmaceuticals in the United States.  The process of
     developing a line of proprietary drugs requires approvals by the Food
     and Drug Administration (FDA) of Abbreviated New Drug Applications
     (ANDA).  While ANDA build-ups have proceeded, the Corporation has
     generated limited sales revenue through December 31, 1996 primarily
     from the acquisition from others of bulk products repackaged by the
     Corporation and distributed under its own label principally to the
     wholesale market including the generic cardiovascular product
     Nifedipine, which has accounted for over 90% of sales volume from
     inception through 1995 and approximately 60% in 1996.

     The Corporation is subject to certain risks associated with companies
     in the pharmaceutical industry. Profitable operations are dependent on
     the Corporation's ability to market its products at reasonable profit
     margins.  In addition to achieving profitable operations, the future
     success of the Corporation will depend, in part, on its continuing
     ability to attract and retain key employees, obtain timely approvals of
     its Abbreviated New Drug Applications (ANDA), develop new products and
     raise in the near term the necessary equity capital to keep the
     Corporation in business.

     Prior to 1996, the Corporation was considered a development stage
     enterprise for financial reporting purposes.  A summary of the
     significant accounting policies consistently applied in the preparation
     of the accompanying financial statements follows:

       Use of Estimates

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

       Going Concern

       The accompanying financial statements have been prepared assuming
       that the Corporation will continue as a going concern, which
       contemplates the realization of assets and the satisfaction of
       liabilities in the normal course of business.

                         NOTES TO FINANCIAL STATEMENTS

                 FOR THE YEARS ENDED DECEMBER 31, 1996 AND 1995




1.   ORGANIZATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
     (CONTINUED)

     The Corporation has not currently achieved sales necessary to support
     operations.  The Corporation has, as of December 31, 1996, a
     stockholders' deficit of $3,098,409 and a working capital deficit of
     $11,530,591.  Realization of a major portion of the assets is dependent
     upon the Corporation's ability to meet its future financing
     requirements and the success of future operations, the outcome of which
     cannot be determined at this time.  These and other factors, including
     being in default of the debt agreement with the Economic Development
     Corporation (EDC) of the City of Detroit in 1996 as described in Note
     4, raise substantial doubt about the Corporation's ability to continue
     as a going concern in the absence of sufficient additional funds and
     the achievement of profitable operations.  The accompanying financial
     statements do not include any adjustments relating to the
     recoverability and classification of asset carrying amounts or the
     amount of liabilities that might be necessary should the Corporation be
     unable to continue as a going concern.

     Management's plans with regard to these matters include:

     -  An attempt to raise up to $7,500,000 in gross proceeds from the sale of 
        its common stock (see below).  If the Corporation is unable to raise    
        approximately $7,500,000 it may have an adverse effect on the           
        Corporation's ability to execute its business plan through 1997.  There 
        can be no assurance that adequate capital can be obtained.              

     -  Continued development of strategic alliances with other drug
        manufacturers whereby the Corporation will, subject to approval of      
        ANDAs, manufacture on behalf of the participating entity for a fee
        (cash or common shares - see below) or, manufacture on its own behalf
        and pay the participating entity a royalty based on sales. 


     On July 11, 1996, the Corporation and an Indian specialty
     pharmaceutical company, Sun Pharmaceutical Industries Ltd. ("Sun
     Pharma") announced that they had signed two non-binding letters of
     intent pursuant to which Sun Pharma would make an initial investment in
     Caraco common stock and sell it certain rights for a number of generic
     pharmaceuticals products.  As revised in the most recent proposal, it
     is contemplated that a) in exchange for 5,300,000 shares of Caraco
     common stock Sun Pharma will invest $7,500,000 to be received by the
     Corporation over a period of one year in four installments, b) the
     number of products to be sold to the Corporation by Sun Pharma is 25
     over a period of five years in exchange for 544,000 shares of Caraco
     common stock to be issued for each product and c) two current Caraco
     shareholder directors will each contribute to the Corporation the
     equivalent of up to $500,000 in cash or in shares of Caraco common
     stock, not to exceed 250,000 shares each.  Consummation of this
     transaction is subject to certain conditions, including completion of
     Sun Pharma's due diligence, clearance from various agencies in the
     Indian government, approval of any EDC modification of debt to
     Caraco, and negotiation and execution of definitive documents.
     Negotiations are continuing at this time.

     If the completion of the agreement with Sun Pharma does not occur and
     the Corporation does not receive the anticipated equity capital, it is
     expected that the Corporation would immediately commence bankruptcy
     proceedings pursuant to Chapter 7 of the Federal Bankruptcy Code of
     1978, as amended.

                 FOR THE YEARS ENDED DECEMBER 31, 1996 AND 1995



1.   ORGANIZATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
     (CONTINUED)

     Cash Equivalents

     For purposes of the statement of cash flows, the Corporation considers
     all highly liquid debt instruments purchased with original maturities 
     of three months or less to be cash equivalents.

     Revenue Recognition

     Revenue is recognized upon the shipment of product with allowances for
     returns and price adjustments in the normal course of business based
     primarily upon actual subsequent activity.  Amounts billed by the
     Corporation, if any, in advance of performance in connection with
     contracts to render certain research and development services are
     deferred.

     Inventories

     Inventories are stated at the lower of cost determined by the first in,
     first-out method or market.  The cost of finished goods includes
     materials and direct labor.  Indirect manufacturing overhead costs have
     not been capitalized and inventoried due to the relatively low levels
     of production volume and plant capacity utilization to date.

     Inventories consist of the following amounts at December 31, 1996:

     The principal components used in the Corporation's business are active
     and inactive pharmaceutical ingredients and certain packaging
     materials.  Many of these components are available only from sole
     source suppliers, most of whom must be FDA approved.  Qualification of
     a new supplier could serve to delay the manufacture of the drug
     involved.

     In 1996 and 1995, the Corporation purchased approximately $334,000 and
     $1,503,000, respectively, of its raw materials in the form of bulk
     Nifedipine pursuant to a supply contract with one vendor.

     In 1996 and 1995, the Corporation purchased raw materials of
     approximately $211,000 and $19,000, respectively, from a business owned
     and controlled by a shareholder director of the Corporation. Included
     in accounts payable at December 31, 1996 is $188,525 due to this
     vendor.

1.   ORGANIZATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
     (CONTINUED)

     Property, Plant and Equipment

     Depreciation is provided for in amounts sufficient to relate the cost
     of property, plant and equipment to operations over their estimated
     service lives using the straight-line method.  Building and
     improvements are depreciated over 40 years.  Management annually
     reviews these assets for impairment and reasonably believes the
     carrying value of these assets will be recovered through cash flow from
     operations assuming Caraco is able to obtain equity financing in
     amounts sufficient to allow the Corporation to carry out its business
     plan.

     Marketable Securities

     Marketable securities consisting of an investment in a publicly held
     company whose stock is traded in the over-the-counter market (Note 6),
     are classified as available-for-sale and are carried at approximate
     market value.  Unrealized holding losses on this investment that are
     considered to be temporary are recognized as a separate component of
     stockholders' deficit.  Declines in value that are considered to be
     other than temporary are recognized as losses in the period such
     determination is made.  Realized gains or losses are determined using
     the specific identification method.

     Federal Income Taxes

     Deferred income tax assets and liabilities are determined based on the
     difference between the financial statement and federal income tax basis
     of assets and liabilities as measured by the enacted tax rates which
     will be in effect when these differences reverse.  The principal
     difference between assets and liabilities for financial statement and
     tax return purposes is attributable to differing depreciation methods
     and the net operating losses.

     Loss Per Share

     Loss per share is computed using the weighted average number of common
     shares outstanding during each year.

     Research and Development Costs

     Research and development costs are charged to expense as incurred.

1.   ORGANIZATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
     (CONTINUED)

     Financial Instruments

     The carrying values of cash equivalents, accounts receivable, and
     accounts payable approximate their values due to the short-term
     maturities of these financial instruments.  The fair value of
     marketable securities is based upon quoted market prices.

     The Corporation does not believe it is practicable to estimate the fair
     value of its note payable to the Economic Development Corporation of
     the City of Detroit.  Management believes the cost to do so would
     exceed the benefits, particularly since such information is not needed
     to manage the business. Further, management does not believe that
     comparable financing would currently be available on similar terms.

     Stock-Based Compensation

     On January 1, 1996, the Corporation adopted the disclosure aspects of
     Statement of Financial Accounting Standards (SFAS) No. 123, "Accounting
     for Stock-Based Compensation".  The Corporation continues to apply
     Accounting Principles Board (APB) Opinion No. 25 in accounting for its
     plans and, accordingly, no compensation cost has been recognized in the
     financial statements for its outstanding stock options.  Companies that
     do not adopt a fair value method contemplated in SFAS No. 123 are
     required to make pro-forma disclosures of net loss and loss per share
     as if they had adopted the fair value accounting method.  The
     Corporation believes the pro-forma impact on net loss and loss per
     share is not significant and is antidilutive.


2.   SUPPLEMENTAL CASH FLOWS INFORMATION

     Non-cash Investing and Financing Activities

     During 1996, the Corporation converted shareholder notes and interest
     owed thereon totaling $250,000 into 111,111 shares of common stock.

     During 1995, the Corporation converted shareholder notes and interest
     owed thereon totaling $730,000 into 584,000 shares of common stock.

     During 1995, the Corporation recorded a contribution to capital of
     $56,000 in recognition of certain administrative costs paid directly on
     its behalf by its then Chairman Emeritus.

4.   DEBT INCLUDING RELATED PARTIES (CONTINUED)

     On December 23, 1996, the Corporation entered into a Secured Promissory
     Note with Sun Pharma Global, Inc. ("Sun"), a wholly owned subsidiary of
     Sun Pharma, in order to borrow $350,000.  Funds were not received until
     January 1997 and, as such, no liability has been recorded as of
     December 31, 1996.

     The note with Sun along with other Secured Promissory Notes with two
     shareholder directors dated January 30, 1997, February 3, 1997 and
     February 11, 1997 in the amounts of $100,000, $300,000 and $200,000,
     respectively, are subject to an Inter-Creditor Agreement. Among other
     things, the Inter-Creditor Agreement provides for an equal priority in
     collateral and principal payments based on each creditors' respective
     share of total debt.
     

     The Sun note and the notes entered into subsequent to December 31, 1996
     all provide for the following terms and conditions:

     -  Interest at 10% per annum (default rate of 12%).
     -  Principal outstanding hereunder, together with all accrued and unpaid
        interest thereon shall be due and payable on;  a) the earlier of (i)
        March 27, 1997, (ii) the closing of a transaction pursuant to which Sun
        Pharma or an affiliate acquire 5.3 million shares of the Common Stock of
        Caraco (the "Proposed Transaction") or (iii) 20 days after delivery of a
        written notice by Sun Pharma to Caraco that Sun Pharma does not intend
        to proceed with and/or continue negotiations regarding the Proposed
        Transaction, unless such failure to proceed constitutes a breach of any
        legal obligation which Sun Pharma may hereafter incur in writing; or b) 
        in any event, upon the occurrence of a default as defined.
     -  The notes are secured by specific equipment which are not subject to any
        EDC liens or encumbrances.


     All principal and unpaid interest relative to the Sun debt is payable
     in cash or may, at the sole and exclusive discretion of Sun, be applied
     as part of the investment pursuant to any Proposed Transaction.

     The interest on the Secured Promissory Notes of the directors issued in
     1997 is payable in cash or common stock of the Corporation at the sole
     discretion of the Corporation.

     Borrowed debt at December 31, 1996 also consists of a note payable to
     the Economic Development Corporation (EDC) of the City of Detroit to
     evidence an obligation to repay funds advanced to the Corporation
     pursuant to a Development and Loan Agreement (the "Agreement") dated
     August 10, 1990 as amended.  The note is collateralized by a first
     mortgage, effectively, on all of the Corporation's property and equipment
     purchased pursuant to the Agreement and repayment is personally guaranteed
     by the Corporation's founder and former Chairman Emeritus and his spouse.

4.   DEBT INCLUDING RELATED PARTIES (CONTINUED)

     Effective April 2, 1993, the Corporation and the EDC of the City of
     Detroit amended the Agreement discussed above.  The amendments
     included:

        
     -  A reduction in the stipulated interest rate from the inception of the 
        loan through April 2, 1993 from 10% to 8 1/2%.  Furthermore, beginning
        April 2, 1993 through maturity, the rate was changed to 9 1/2% (prior to
        further amendments, as described below).

     -  An increase in the City of Detroit's subordinate position in the
        Corporation's operating facility from $1,000,000 to $3,000,000.


     Effective March 1, 1994, the Agreement was modified to extend the
     maturity date and provide for monthly payments of interest only through
     December of 1995 and from January 1996 through June 2002 monthly
     payments of principal and interest at which point a balloon payment of
     $5,579,000 is due.  The required monthly interest only payments
     discussed above were approximately $55,000 through December 1, 1995.
     Effective January 1, 1996, monthly principal and interest payments
     approximate $95,000 until decreasing to approximately $89,000 in 2002.
     The interest rate, as modified, ranges from approximately 5.0% - 6.5%
     throughout the term of the Agreement.  In addition, effective February
     28, 1995 a further amendment was made to release from encumbrance
     certain assets not purchased with original EDC funds.

     The Agreement also contains certain operating covenants which limit
     certain activities of the Corporation, consisting primarily of a
     restriction on the sale or disposal of the Corporation's operating
     facility.  In addition, the Corporation may be subject to contingent
     interest payments equal to 10% of the net proceeds from any sale or
     disposition of any collateralized property purchased with "Section 108
     Funds", as defined.

     Scheduled aggregate principal maturities of this note are summarized as
     follows:

4.   DEBT INCLUDING RELATED PARTIES (CONTINUED)

     The Corporation is currently in default on the EDC debt and is
     negotiating with the EDC to further modify the terms of the loan.

     On November 1, 1996, the EDC made a proposal to defer payments on the
     loan for the period March 1996 through January 1999 subject to the
     completion of the Sun Pharma agreement.  The deferral was designed to
     aid the Corporation and Sun Pharma in achieving adequate cash flow
     during the next few years to assure Caraco's ability to both fund its
     current operations and continue its new product ANDA approval process.
     Monthly payments were to resume in February 1999 or sooner should the
     Corporation reach profitability levels of $750,000 in any quarter
     through March 31, 1998 and a level of $500,000 in the quarters ended
     June 30, 1998 and September 30, 1998.  When payments are resumed they
     would include a portion of the deferral which would be apportioned over
     the remaining term of the loan.

     As a condition of the deferral, the EDC would then have additional
     security on all the Corporation's existing equipment and the
     Corporation would be required to comply with several additional
     financial and operating covenants which include maintaining a tangible
     net worth of not less than $1,000,000 (excluding debt subordinated to
     the EDC), limiting capital expenditures to under $2,000,000 and
     abstaining from share redemption during the payment deferral period.

     The EDC's proposal to the Corporation terminated on March 17, 1997 and
     was subject to certain conditions that the Corporation has not met; as
     such, the EDC obligation is classified as current on the accompanying
     balance sheet.  The Corporation is continuing to negotiate with the
     EDC.  If no agreement is reached, the EDC may initiate foreclosure
     proceedings on the collateral.


5.   INCOME TAXES

     At December 31, 1996 a deferred income tax asset and related valuation
     allowance, attributable primarily to the net operating loss
     carryforward (calculated using a 34% tax rate) of approximately
     $7,100,000 has been established.  Changes in the valuation allowance
     were approximately $1,800,000 and $1,400,000 in 1996 and 1995,
     respectively

     At December 31, 1996, net operating loss carryforwards of approximately
     $21,000,000 are available to offset future federal taxable income, if
     any, through 2011.

6.   STOCKHOLDERS' DEFICIT

     Common Stock Issuances

     On February 23, 1995, the Corporation sold 454,918 shares of its common
     stock at $3.00 per share, netting approximately $1,320,000.  This
     amount includes 101,250 shares which were issued to a current
     shareholder (now a director) of the Corporation in exchange for 45,000
     unregistered common shares held by the individual in an enterprise
     whose stock is traded over-the-counter.  As of December 31, 1996 the
     Corporation had received 42,913 of such shares; the value measured on
     February 23, 1995 of the remaining 2,087 shares is presented as a
     subscription receivable on the accompanying balance sheet. As of
     December 31, 1995, the value of the 42,913 shares of stock received by
     the Corporation had decreased by $160,924 which was reflected on the
     December 31, 1995 balance sheet as an unrealized loss on
     available-for-sale marketable securities.  As of December 31, 1996, the
     value of the 42,913 shares had decreased by $194,750.  At that date,
     the decline is considered to be other than temporary and accordingly,
     the Corporation recognized a loss.

     On June 30, 1995, the Corporation sold 1,208,000 shares of its common
     stock at $1.25 per share, netting approximately $1,470,000.  Of the
     total shares issued, 400,000 shares were beneficially owned by the
     former Chairman Emeritus and had been held in escrow since completion
     of the initial public offering. This issuance also includes 584,000
     shares which were issued in consideration of cancellation of
     Corporation indebtedness of $730,000, resulting in the receipt of net
     cash proceeds of $780,000.

     On October 31, 1995, the Corporation completed a private placement of
     533,000 shares of the Corporation's common stock at $2.50 per share
     that netted the Corporation approximately $1,276,000 in cash proceeds.

     On March 31, 1996, the Corporation converted a $250,000 shareholder
     loan into 111,111 shares of its common stock at $2.25 per share.

     In connection with a private placement offering that was completed
     effective March 31, 1996, the Corporation sold 572,444 shares of common
     stock at $2.25 per share, netting approximately $1,288,000.

     On May 13, 1996, the Corporation sold privately 44,444 shares of common
     stock at $2.25 per share, netting $100,000.

     On May 31, 1996, the Corporation sold privately 250,000 shares of
     common stock at $2.00 per share, netting $500,000.

6.   STOCKHOLDERS' DEFICIT (CONTINUED)

     The Corporation's common stock and warrants are quoted on the OTC
     Bulletin Board following a delisting of its securities from the NASDAQ
     Small Cap Market in July 1996 for not maintaining minimum capital and
     surplus requirements of $1 million.  The Corporation intends to raise
     additional capital and seek reinstatement on NASDAQ.

     Preferred Stock

     The Corporation has authorized 5,000,000 shares of preferred stock
     which are issuable in series with the terms and amounts set at the
     Board of Directors discretion.

     Each share of preferred stock is nonvoting and is convertible into one
     share of common stock through January 1, 2004.  The preferred shares
     require dividends of $.21 per share on a cumulative basis commencing in
     1997.

     Incentive Stock Option Plan

     Pursuant to the terms of an incentive stock option plan established in
     April 1993 and subsequently amended in 1995, the Corporation may grant
     options for the purchase of up to 450,000 shares of common stock.
     Options granted are exercisable ratably over five years on a cumulative
     basis.  Activity with respect to these options is summarized as
     follows:

6.   STOCKHOLDERS' DEFICIT (CONTINUED)

     Other Common Stock Option Arrangements

     Pursuant to a strategic alliance formalized by an agreement for the
     acquisition of certain technology with a third-party pharmaceutical
     company ("Hexal"), the Corporation granted to Hexal  (i) a "sign-up"
     option to purchase 100,000 shares of the Corporation's common stock at
     a price of $3.50 per share and (ii) a "product" option to purchase a
     presently indeterminable number of common shares at an exercise price
     equivalent to their fair value, as defined, upon the filing of an ANDA
     related to a certain generic drug. Such options may be exercised and
     payment for shares may be made only out of royalties payable by the
     Corporation to Hexal for sales, if any, of the related product.

     Other Common Stock Purchase Warrant and Option Agreements

     As of December 31, 1996, warrant and option agreements totaling
     2,861,089 shares of common stock are outstanding at exercise prices
     ranging from $1.31 to $18.20 per share or unit, exercisable at various
     dates through October 2006.  No warrants or options under these
     agreements have been exercised.


7.   EMPLOYMENT AGREEMENTS

     During 1993 and 1994 the Corporation entered into employment agreements
     with certain officers. Annual commitments under these contracts
     approximate $493,000 through 1998.

     In the event of certain terminations of employment (as defined) the
     officers would be entitled to receive, among other things, their base
     salaries for periods ranging from twelve to eighteen months from the
     date of separation.  In addition, in the event of a change in control
     or ownership (as defined) of the Corporation, the Corporation's
     President would be entitled to receive a lump sum severance payment
     equal to three years' base salary plus certain performance bonuses.


8.   OTHER MATTERS

     During the year ended December 31, 1994, the Corporation determined
     that approximately $514,000 of Corporation funds had been
     misappropriated by the Corporation's former controller, a son of the
     Corporation's former Chairman Emeritus. The misappropriations occurred
     during the period from January through June of 1994.  The Corporation's
     former Chairman Emeritus reimbursed the Corporation the $514,000.  In
     connection with this matter, approximately $56,000 in certain legal and
     other expenses incurred by the Corporation in conducting an
     investigation into this matter were paid directly by the former Chairman
     Emeritus from his personal funds.  These expenses have been recognized in
     the accompanying 1995 statement of operations with a corresponding credit
     to common stock.

                 FOR THE YEARS ENDED DECEMBER 31, 1996 AND 1995





8.   OTHER MATTERS (CONTINUED)

     The Corporation has made filings about this matter with the Securities
     and Exchange Commission (SEC).  The SEC is currently conducting an
     investigation into the matter.  On November 1, 1996, the Corporation,
     through its legal counsel,  was notified by the SEC that its
     Enforcement Division has tentatively decided not to recommend that the
     Commission authorize an enforcement action against the Corporation.
     The SEC further advised that it nevertheless was possible that an
     action against the Corporation may ultimately result from the
     investigation.  The SEC's investigation had revealed that the
     defalcation which was reported October 18, 1994 had also occurred in
     1993, as well as in the first half of 1994, and that the 1993
     defalcation had totaled at least an additional $300,000.  It is also
     possible that the Commission might institute an enforcement proceeding
     against one or more former employee(s) of the Corporation who are no
     longer associated with the Corporation.


9.   MAJOR CUSTOMERS

     Shipments to one wholesaler customer (Amerisource) accounted for
     approximately 20% and 23% of net sales in 1996 and 1995, respectively.
     Balances due from this customer represented approximately 22% of
     accounts receivable at December 31, 1996.  Shipments to another
     wholesale customer (McKesson Drug) accounted for approximately 17% of
     net sales in 1996.
