                      THIRD AMENDMENT TO CREDIT AGREEMENT


     THIS THIRD AMENDMENT TO CREDIT  AGREEMENT,  dated as of July 31, 1995 (this
"Third Amendment"),  between HURCO COMPANIES,  INC., an Indiana corporation (the
"Company"), and NBD BANK, a Michigan banking corporation (the "Bank").

                                    RECITALS

     A. The parties hereto have entered into a Credit Agreement and Amendment to
Term Loan  Agreement,  dated as of March  24,  1994,  as  amended  (the  "Credit
Agreement"), which is in full force and effect.

     B. The Company  desires to amend the Credit  Agreement as herein  provided,
and the Bank is  willing  to so amend  the  Credit  Agreement  on the  terms and
conditions set forth herein.

                                   AGREEMENT

     Based upon these recitals, the parties agree as follows:

     1.  AMENDMENT.  Upon the Company  satisfying  the  conditions  set forth in
paragraph 4 (the date that this occurs being called the "effective  date"),  the
Credit Agreement shall be amended as follows:

          (A) The term "Automatic Termination Date" in Section 1.1 of the Credit
          Agreement is amended to read as follows:  "AUTOMATIC TERMINATION DATE"
          means November 1, 1996.

          (B) New Sections 7.1(i) and 7.1(l) are added, to read as follows:

          (I) MOST  FAVORED  LENDER.  In the event that the Company  shall enter
          into any  modification of the PML Note Agreement or any other contract
          or agreement  pursuant to which the Company shall have available to it
          a credit  facility (a "Credit  Agreement"),which  increases  the fees,
          expenses,  interest  rate spreads over prime rate,  LIBOR rate, or any
          other such base rate or any other  charges which are or may be payable
          to a  lender  pursuant  to  a  Credit  Agreement  (but  excluding  (I)
          reimbursements for actual out-of-pocket  expenses of the lender or its
          counsel and excluding reasonable commitment fees to obtain,  increase,
          or extend or renew a credit  facility,  including  lines of credit and
          term loan facilities,  default rate interest,  and reasonable fees and
          expenses or costs  actually  incurred  for  collection  arising out of
          default  under any Credit  Agreement  AND (II) ANY  INCREASES IN FEES,
          EXPENSES, INTEREST RATE SPREADS, BASE RATES OR OTHER CHARGES RESULTING
          SOLELY FROM THE OPERATION OF SECTION 6.14 OF THE PML NOTE AGREEMENT OR
          ANY  COMPARABLE  PROVISION  OF ANY OTHER  CREDIT  AGREEMENT)  over the
          interest rate spreads, fees, charges, and expenses provided for in the
          PML Note  Agreement or such other  Credit  Agreement,  as  applicable,
          then,  effective  as of the date of such  increase,  the amount of the
          increase in the interest rate spread (i.e., the number of basis points
          added to the  interest  rate  spread),  if any,  shall be added to the
          interest rate payable to NBD under the Notes issued in connection with
          this Agreement,  as amended,  and as and when the amount  representing
          the increase of fees,  expenses,  and/or charges,  if any, becomes due
          and payable under the Credit Agreement, the Company shall pay to NBD a
          comparable  amount as a fee.  In no event will the fee  payable to NBD



          pursuant  to the  foregoing  exceed  the  amount of the  corresponding
          increase in fee, charge,  or expense payable under the modified Credit
          Agreement.  Failure of the Company to make the  payments  which become
          due and  payable  under  this  Section  shall  constitute  an Event of
          Default under Section  8.1(a).  Upon any increase in the interest rate
          to be charged under the Notes  pursuant to this  Section,  the Company
          shall execute such  amendments to the Notes and this  Agreement as NBD
          may  reasonably  request to confirm and  evidence  the increase in the
          interest rate.

          (l) COMMON  COVENANTS.  During the  period  from May 1, 1996,  through
          October 31, 1996, the Company agrees to immediately and  automatically
          grant NBD the same loan covenants,  including financial covenants, and
          terms it grants PML or any  replacement  lender  therefor  during such
          period,  if such  covenants  and terms are  different  in kind or more
          restrictive  (on the Company) than NBD's existing  covenants or terms.
          If the Company  defaults in the  performance  of such new covenants or
          terms, an Event of Default shall arise under Section 8.1(c).

          (C) Section  7.2(c)(iii) is amended by adding the following  after the
          phrase "second fiscal quarter of fiscal year 1996":

                  ,and $1,500,000 in the aggregate during the fiscal year 1996

          (D) Section  7.2(e) is amended by adding the phrase  "through July 30,
          1996"  after the word  "thereafter"  in the  column  entitled  "Fiscal
          Period  Ended",  and adding the following  dates and amounts under the
          headings "Fiscal Period Ended" and "Calculated Amount":

               FISCAL PERIOD ENDED                             CALCULATED AMOUNT

                July 31, 1996                                      $6,500,000

                October 31, 1996                                   $7,000,000

          (E) Section  7.2(e) is further  amended by adding the following to the
          end of the subsection:

                  ,  provided,  however,  that in the event there is any capital
                  contribution  or cash infused by shareholders or third parties
                  to  the  Company  ("Equity  Infusion"),  then  the  Calculated
                  Amounts set forth above for the fiscal period during which the
                  Equity  Infusion  is made and each  fiscal  period  thereafter
                  shall  be  increased  by  85%  of the  amount  of  the  Equity
                  Infusion.

          (F)  Section  7.2(I) is  amended by  deleting  the phrase "at any time
          thereafter." and substituting the following:

                  from November 1, 1994, through July 30, 1996, or to exceed 4.5
                  to 1.0 from July 31, 1996,  through  October 30,  1996,  or to
                  exceed  4.0  to 1.0  on  October  31,  1996,  or at  any  time
                  thereafter,  provided, however, that in the event there is one
                  or more Equity Infusions which aggregate at least  $3,000,000,
                  then the Company shall not permit such ratio to exceed 3.55 to
                  1.0 on July 31, 1996, or at any time thereafter.



          (G) Section  7.2(m) is amended by adding the  following  at the end of
          that subsection:

                  Company or any of its Subsidiaries during the third and fourth
                  fiscal  quarters of fiscal year 1996,  when  combined with all
                  other Capital Expenditures made during that fiscal year, would
                  exceed $1,750,000
