                  CARACO ANNOUNCES FINALIZATION OF AGREEMENTS

        Detroit, MI, August 21, 1997 -- Caraco Pharmaceutical Laboratories,
Ltd. (Bulletin Board: CARA) today announced that it has completed the
transaction with Sun Pharma (Sun) of India in which Sun will infuse $7.5
million in cash over the next 18 months and provide technology for twenty-five
products over the next five years, valued at over $14 million.

        The finalization of the Sun-Caraco agreement also makes effective the
agreement between Caraco and the Economic Development Corporation of Detroit
(EDC) whereby payments on the $8.8 million mortgage note from the EDC will be
postponed until February 1999.  In addition, short term demand notes of
approximately $2 million dollars are in the process of being restructured.  The
revised terms currently provide for the principal to be due August 1, 1999 with
interest at 10% to be prepaid in exchange for an equivalent number of shares of
common stock of the corporation at $1.50 per share.  The notes also contain a
common stock conversion option until maturity at the same price per share.

        In connection with the consummation of the Sun transaction, and Sun's
impending acquisition of 5.3 million shares of Caraco common stock, Caraco's
Board of Directors will be restructured.

        "Looking towards an expeditious entrance into the US market, Sun Pharma
evaluated a number of opportunities and generic products and found Caraco
offered the synergy for development, manufacture, and marketing of generic
pharmaceutical products" said Narendra Borkar, Sun Pharma Director and Caraco
CEO Designate.

        "Both companies recognize the vast potential for advancements in the
pharmaceutical market that this strategic alliance affords and we are excited
that the agreement has finally been completed.  We can now begin to grow the
company through aggressive product development and marketing programs."  Said
William Hurd, President of Caraco.

        During the last six months, Sun has been working on a strategic plan
for introduction of new products which will be instituted immediately.  Sun
