Mr. Dennis A. Bertram
5482 Parkside Drive
Brighton, MI  48116

Dear Mr. Bertram:

Amcast Industrial Corporation, an Ohio corporation (the "Company"), considers
the establishment and maintenance of a sound and vital management to be
essential to protecting and enhancing the best interests of the Company and its
shareholders. In this connection, the Company recognizes that, as is the case
with many publicly held corporations, the mere possibility of a change in
control may raise distracting and disrupting uncertainties and questions among
management personnel, may interfere with their whole-hearted attention and
devotion to the performance of their duties, and may even lead to their
departure, all to the detriment of the best interests of the Company and its
shareholders. Accordingly, the Board of Directors of the Company (the "Board")
has determined that the best interests of the Company and its shareholders would
be served by assuring to certain executives of the Company, including yourself,
the protection provided by an agreement which defines the respective rights and
obligations of the Company and the executive in the event of termination of
employment subsequent to a change in control of the Company.

In order to induce you to remain in the employ of the Company, this letter
agreement sets forth the severance benefits which the Company agrees will be
provided to you in the event your employment with the Company [or, in the case
of a transaction described in clause (iv) of paragraph 2, with the successor to
the Company (a "Successor")] is terminated subsequent to a "change in control of
the Company" under the circumstances described below.

Except where the context otherwise indicates, the term "Company" hereinafter
includes the Company and any Successor.

1. OPERATION AND TERM OF AGREEMENT. This agreement, although effective
   immediately, shall not become operative unless and until there has been a
   change in control of the Company. None of the provisions of this agreement
   shall be applicable 



                                      165

                                                               September 1, 1996
                                                                          page 2

   to any termination of your employment, however occurring, which is effective
   prior to a change in control of the Company. This agreement shall continue
   until the later of December 31, 2000 or two years after the occurrence of a
   change in control of the Company, provided such change in control occurs on
   or before December 31, 2000, subject to extension beyond that date by mutual
   written consent. The Company will review this agreement with you between
   January 1, 2000 and July 31, 2000, for the purpose of determining whether or
   not an extension beyond December 31, 2000 is mutually agreeable and, if so,
   on what basis and for how long.

2. CHANGE IN CONTROL. No benefits shall be payable hereunder unless there shall
   have been a change in control of the Company, as set forth below, and your
   employment with the Company shall thereafter have been terminated in
   accordance with paragraph 3 below. For purposes of this agreement, a "change
   in control of the Company" shall mean and be deemed to have occurred on (i)
   the date upon which the Company is provided a copy of a Schedule 13D, filed
   pursuant to Section 13(d) of the Securities Exchange Act of 1934 (the "1934
   Act"), indicating that a group or person, as defined in Rule 13d-3 under the
   1934 Act, has become the beneficial owner of 20% or more of the outstanding
   Voting Shares of the Company or the date upon which the Company first learns
   that a person or group has become the beneficial owner of 20% or more of the
   outstanding Voting Shares of the Company if a Schedule 13D is not filed; (ii)
   the date of a change in the composition of the Board of Directors of the
   Company such that individuals who were members of the Board of Directors on
   the date two years prior to such change (or who were subsequently elected to
   fill a vacancy in the Board, or were subsequently nominated for election by
   the Company's shareholders, by the affirmative vote of at least two-thirds of
   the directors then still in office who were directors at the beginning of
   such two year period) no longer constitute a majority of the Board of
   Directors of the Company; (iii) the date the shareholders of the Company
   approve a merger or consolidation of the Company with any other corporation,
   other than a merger or consolidation which would result in the holders of the
   Voting Shares of the Company outstanding immediately prior to the merger or
   consolidation continuing to own immediately after the merger or consolidation
   80% or more of the Voting Shares of the Company or the surviving entity, if
   the Company is not the surviving entity in the merger or consolidation; or
   (iv) the date shareholders of the Company approve a plan of complete
   liquidation of the Company or an agreement for the sale or disposition by the
   Company of all or substantially all the Company's assets. "Voting Shares"
   means any securities of the Company which vote generally in the election of
   directors.

3. TERMINATION FOLLOWING CHANGE IN CONTROL.

   (A) If any of the events described in paragraph 2 constituting a change in
       control of the Company shall have occurred, then upon any subsequent
       termination of your

                                                               September 1, 1996
                                                                          page 3


       employment at any time within two years following the occurrence of such
       event, you shall be entitled to the benefits provided by this agreement,
       as set forth in paragraph 5, unless such termination is (i) by the
       Company for Cause or because of your Disability, or (ii) because of your
       Retirement, or (iii) by you other than for Good Reason, or (iv) because
       of your death.

   (B) As used in this agreement, the terms "Cause", "Retirement", "Good
       Reason", and "Disability" shall have the meanings set forth below:

        (i)   CAUSE. "Cause" shall mean (a) the willful and continued failure by
              you to substantially perform your duties with the Company (other
              than any such failure resulting from your physical or mental
              illness or other physical or mental incapacity), after a demand
              for substantial performance is delivered to you by the Board which
              specifically identifies the manner in which the Board believes
              that you have not substantially performed your duties, or (b) the
              willful engaging by you in gross misconduct which is materially
              and demonstrably injurious to the Company resulting or intended to
              result, directly or indirectly, in substantial personal gain or
              substantial personal enrichment at the expense of the Company. For
              purposes of this subparagraph, no act, or failure to act, on your
              part shall be considered "willful" unless done, or omitted to be
              done, by you not in good faith and without reasonable belief that
              your action or omission was in the best interests of the Company.
              Notwithstanding the foregoing, Cause shall not be deemed to exist
              unless and until there shall have been delivered to you a copy of
              a resolution duly adopted by the affirmative vote of not less than
              three-fourths of the number of directors then in office at a
              meeting of the Board called and held for that purpose (after
              reasonable notice to you and an opportunity for you, together with
              your counsel, to be heard before the Board), finding that in the
              good faith opinion of the Board you were guilty of conduct set
              forth above in clauses (a) or (b) of the first sentence of this
              subparagraph and specifying the particulars thereof in detail.

        (ii)  RETIREMENT. "Retirement" shall mean cessation of your employment
              in accordance with the Company's retirement policy (including
              early retirement) generally applicable to salaried employees, or
              in accordance with any retirement arrangement with respect to you
              established with your consent.

        (iii) GOOD REASON. "Good Reason" shall mean:



                                      167
<PAGE>   5
                                                               September 1, 1996
                                                                          page 4


        (a)   The assignment to you of any duties inconsistent with your
              position, duties, responsibilities and status with the Company
              immediately prior to a change in control of the Company, or a
              change in your responsibilities, as in effect immediately prior to
              a change in control of the Company, which materially diminishes
              your responsibilities with the Company when considered as a whole,
              or any removal of you from or any failure to re-elect you to any
              of such positions or offices; provided, however, that the
              foregoing shall not constitute Good Reason if done in connection
              with termination of your employment because of your Retirement, or
              by the Company for Cause or because of your Disability, or by you
              other than for Good Reason.

        (b)   A reduction by the Company of your then current annual base salary
              or, if higher, your annual base salary as in effect at the time of
              the change in control of the Company.

        (c)   Failure by the Company to continue in effect any benefit,
              incentive compensation, pension, employee stock ownership, stock
              option, life insurance, medical, health and accident, or
              disability plan in which you are participating at the time of a
              change in control of the Company or plans providing you with
              substantially similar benefits, or the taking of any action by the
              Company which would adversely affect your participation in or
              materially reduce your benefits under any of such plans or deprive
              you of any material fringe benefit enjoyed by you at the time of
              the change in control of the Company, or the failure by the
              Company to provide you with the number of paid vacation days to
              which you would then be entitled in accordance with the Company's
              vacation policy in effect at the time of the change in control of
              the Company.

        (d)   The relocation of the Company's principal executive offices to a
              location outside Montgomery County, Ohio, if at the time of a
              change in control of the Company you are based at the Company's
              principal executive offices.

        (e)   The Company's requiring you to be based anywhere other than the
              location where you are based at the time of a change in control of
              the Company, if the same requires you to relocate your principal
              residence; or, in the event you consent to being based anywhere
              other than such location, the failure by the Company to pay (or
              reimburse you for) all reasonable moving expenses incurred by you
              relating to a change of your principal residence in connection
              with such relocation

                                                                          page 5


              and to indemnify you against any loss [defined as the difference
              between the higher of (1) your aggregate investment in such
              residence or (2) the fair market value of such residence, as
              determined by a real estate appraiser designated by you and
              reasonably satisfactory to the Company, and the actual sale price
              of such residence after the deduction of all real estate brokerage
              charges and related selling expenses] realized upon the sale of
              such residence in connection with any such change of residence.

        (f)   The Company's requiring you to perform duties or services which
              necessitate absence overnight from your place of residence,
              because of travel involving the business or affairs of the
              Company, to a degree not substantially consistent with the extent
              of such absence necessitated by such travel during the period of
              twelve months immediately preceding a change in control of the
              Company, except to the extent that such travel or absence is in
              connection with the finalization of the transaction resulting in
              the change of control, and does not continue for more than 90 days
              after the final closing of the transaction.

        (g)   The failure of the Company to obtain the assumption of this
              agreement by any Successor as provided in paragraph 7 hereof.

        (h)   The Company's termination of your employment without satisfying
              any applicable requirements of paragraph 4 and subparagraph B (i)
              above.

   (iv)  DISABILITY.  "Disability" shall mean your inability to perform the 
         duties required of you on a full-time basis for a period of six
         consecutive months because of physical or mental illness or other
         physical or mental disability or incapacity, followed by the Company
         giving you thirty days' written notice of its intention to terminate
         your employment by reason thereof, and your failure because of physical
         or mental illness or other physical or mental disability or incapacity
         to resume the full-time performance of your duties within such period
         of thirty days and thereafter perform the same for a period of two
         consecutive months.

   (C) During any period of time subsequent to a change in control of the
       Company, if you fail to perform your duties as a result of physical or
       mental illness or other physical or mental disability or incapacity, you
       shall continue to receive your full salary at your annual base salary
       rate then in effect, together with incentive compensation (as defined in
       paragraph 5A accrued but not paid prior to your Date of Termination) as
       defined in paragraph 4 until you return to work or your

       employment with the Company is terminated; provided, however, that any
       amount otherwise payable for any period of time pursuant to this
       subparagraph (C) shall be reduced by any payment or payments you receive
       for such period of time under any employee salary continuation plan or
       employee disability insurance plan maintained by the Company no part of
       the cost of which was paid or is payable by you.

   (D) If subsequent to a change in control of the Company your employment is
       terminated by the Company for Cause, the Company shall pay you your full
       salary through the Date of Termination at your annual base salary rate in
       effect at the time Notice of Termination is given, and you shall also
       receive all accrued or vested benefits of any kind to which you are, or
       would otherwise have been, entitled through the Date of Termination (as
       defined in paragraph 4), and the Company shall thereupon have no further
       obligation to you under this agreement.

4. NOTICE AND DATE OF TERMINATION.

   (A) Any termination of your employment subsequent to a change in control of
       the Company shall be consummated by written Notice of Termination given
       to the other party. For purposes of this agreement, "Notice of
       Termination" shall mean a notice which indicates the specific termination
       provision or provisions in this agreement relied upon, if any, and sets
       forth in reasonable detail the facts and circumstances claimed to provide
       a basis for termination of your employment.

   (B) "Date of Termination" shall mean (i) if your employment is terminated by
       the Company for Cause, the date specified in the Notice of Termination or
       the date on which the meeting of the Board referred to in subparagraph
       3(B)(i) is concluded, whichever date is the later; or (ii) if your
       employment is terminated for any other reason, the date on which Notice
       of Termination is given or the effective date specified in the Notice,
       whichever is later. For purposes of this agreement, termination of your
       employment shall be deemed to have occurred within two years following
       the occurrence of a change in control of the Company if the Date of
       Termination is within such two year period.

5. COMPENSATION AND BENEFITS UPON TERMINATION.

   (A) "Incentive Compensation" shall mean the annual cash payment awarded under
       the Annual Incentive Program (AIP) or other plan which replaces the AIP
       but not including any awards under any stock option, stock grant, stock
       rights, or 


                                      170

                                                                          page 7


       similar plan or any award under any company sponsored profit sharing,
       pension, 401k, or similar savings plan.

   (B) The compensation and benefits to be provided to you pursuant to paragraph
       3 of this agreement upon termination of your employment with the Company
       under specified circumstances within two years following a change in
       control of the Company include the following:

         (i) Subject to the provisions of paragraph 8 hereof, the Company
             shall pay to you as severance pay in a lump sum in cash on
             the Date of Termination, the following amounts:

            (a) Your full salary through the Date of Termination at your
                annual base salary rate in effect at the time Notice of
                Termination is given; and also the amount of Incentive
                Compensation to any completed period or periods which has
                been earned by or awarded to you but which has not yet
                been paid to you.

            (b) In lieu of any further salary payments to you for periods
                subsequent to the Date of Termination, an amount (the
                "Additional Compensation Payment") equal to two hundred
                percent (200%) of the sum of your annual base salary at

                higher, at the rate in effect at the time of the change in
                control) plus an amount equal to two hundred percent
                (200%) of the average annual amount awarded to you as
                Incentive Compensation for the two years immediately
                preceding the year during which the Date of Termination
                occurs (whether or not fully paid).

            (c) An amount in cash equal to the aggregate spread between
                the exercise prices of all options granted to you under
                the Company's existing stock option plans or any stock
                option plan adopted by the Company subsequent to the date
                hereof ("Options") which are then outstanding, whether or
                not then fully exercisable, and the higher of (a) the Fair
                Market Value of Common Share of the Company ("Company
                Shares") on the Date of Termination or (b) the average
                price per Company Share actually paid by the acquiring
                party in connection with any change in control of the
                Company. As used in this subparagraph, "Fair Market Value"
                shall mean (1) in the event the Company Shares are listed
                on any exchange or in the NASD National Market System, the
                last sale price on such exchange or System on the Date of
                Termination (or last trading date prior thereto) or, if
                there are no sales on such date, the mean between the
                representative bid and asked prices for Company

                Shares on such exchange or System at the close of business on 
                such date or (2) in the event that there is then no public
                market for the Company Shares or that trading in the
                Company Shares is sporadic and the mean between any bid
                and asked prices is not representative of fair market
                value, the fair market value of the Company Shares
                determined in accordance with ss.2031-2(f) of the Treasury
                Regulations or any successor provision thereto. Any Option
                for which payment is made as prescribed in this
                subparagraph (c) shall be canceled effective upon the
                making of such payment.

            (d) All legal fees and expenses reasonably incurred by you in
                good faith as a result of such termination (including all
                such fees and expenses, if any, incurred in contesting or
                disputing any such termination or in seeking to obtain or
                enforce any right or benefit provided by this agreement).

            (e) Interest at the rate of 10 percent per annum, compounded
                daily from the due date of any payment required to be made

                through the date such payment is actually made.

          (ii)The Company shall, at its expense, maintain in full force
              and effect for your continued benefit all life insurance,
              medical, health, and accident plans, programs and
              arrangements in which you were entitled to participate at
              the time of the change in control, provided that your
              continued participation is possible under the terms of such
              plans, programs and arrangements. In the event that the
              terms of any such plan, program, or arrangement do not
              permit your continued participation or that any such plan,
              program or arrangement has been or is discontinued or the
              benefits thereunder have been or are materially reduced, the
              Company shall arrange to provide, at its expense, benefits
              to you which are substantially similar to those which you
              were entitled to receive under such plan, program or
              arrangement at the time of the change in control. The
              Company's obligation under this subparagraph (ii) shall
              terminate on the earliest of the following dates: (a) the
              second anniversary date of the Date of Termination, (b) the
              date an essentially equivalent and no less favorable benefit
              is made available to you by a subsequent employer or (c) the
              date that would have been your normal retirement date under
              the Company's defined benefit pension plan for salaried
              employees had your remained employed by the Company.

          (iii) In the event that because of their relationship to you,
              members of your family or other individuals are covered by
              any plan, program, or

                                                                          page 9


              arrangement described in subparagraph (ii) above immediately prior
              to the Date of Termination, the provisions set forth in
              subparagraph (ii) shall apply equally to require the continued
              coverage of such persons; provided, however, that if under the
              terms of any such plan, program or arrangement any such person
              would have ceased to be eligible for coverage during the period in
              which the Company is obligated to continue coverage for you,
              nothing set forth herein shall obligate the Company to continue to
              provide coverage for such person beyond the date such coverage
              would have ceased even if you had remained an employee of the
              Company.

          (iv)The Company shall enable you to purchase the automobile, if
              any, which the Company was providing for your use at the
              time Notice of Termination was given at the wholesale value
              as set out in the latest Black Book published by National
              Auto Research Division of Hearst Business Media Corporation,
              of such automobile at such time.

   (B) If an event constituting Good Reason shall occur, you shall be entitled
       to the compensation and benefits described in (A) above only if you give
       a Notice of Termination with respect thereto within 90 days after the
       occurrence of such event, regardless of whether there has been an
       intervening termination of your employment by the Company or otherwise.

   (C) You shall not be required to mitigate the amount of any payment provided
       for in this agreement by seeking other employment or otherwise; provided,
       however, that in the event that you shall obtain other employment at any
       time within two years immediately following your Date of Termination, 20%
       of all earnings obtained by reason of such other employment during the
       two year period immediately following your Date of Termination shall be
       payable to the Company in full satisfaction of any obligation you have to
       mitigate payment made to you by the Company. Upon obtaining any such
       other employment, you, within thirty (30) days thereof, shall notify the
       Company in writing of such other employment and the aggregate
       compensation (including Incentive Compensation, bonuses and all other
       forms of cash and contingent remuneration) to which you will be entitled.
       During each of the two years immediately following your Date of
       Termination, you shall provide the Company, on or before April 15 of each
       year following such year, a photostatic copy of your federal income tax
       return (including all schedules and exhibits thereto), as filed with the
       Internal Revenue Service for the preceding calendar year.

6.   RIGHTS AS FORMER EMPLOYEE. Nothing contained in this agreement shall be
     construed as preventing you, and shall not prevent you, following any
     termination of 


                                      173

                                                                         page 10

     your employment whether pursuant to this agreement or otherwise, from
     thereafter participating in any benefit or insurance plans, programs or
     arrangements (including without limitation, any retirement plans or
     programs) in the same manner and to the same extent that you would have
     been entitled to participate as a former employee of the Company had this
     agreement not have been executed, except, however, you shall not be
     entitled to any severance payments under any severance pay programs of the
     Company (other than this agreement) if you are paid the benefits provided
     for under this agreement.

7.   SUCCESSORS. The Company shall require any Successor (whether direct or
     indirect, by purchase, merger, consolidation or otherwise) to
     all or substantially all of the business and/or assets of the Company, by
     agreement in form and substance satisfactory to you, to expressly assume
     and agree to perform this agreement in the same manner and to the same
     extent that the Company would be required to perform it if no such
     succession had taken place. Failure of the Company to obtain such agreement
     prior to the effectiveness of such succession shall be a breach of this
     agreement and shall entitle you to compensation from the Company in the
     same amount and on the same terms as you would be entitled hereunder if you
     terminated your employment for Good Reason, except that for purposes of
     implementing the foregoing, the date on which any such succession becomes
     effective shall be deemed the Date of Termination.

     This agreement shall inure to the benefit of and be enforceable by your
     personal or legal representatives, executors, administrators, successors,
     heirs, distributees, devisees and legatees. If you should die while any
     amounts would still be payable to you hereunder if you had continued to
     live, all such amounts, unless otherwise provided herein, shall be paid to
     such beneficiary or beneficiaries as you shall have designated by written
     notice delivered to the Company prior to your death or, failing such
     written notice, to your estate.

         five (5) years following the termination of such employment, you hereby
         agree that you will not, without the written consent of the Board or a
         person authorized thereby, disclose to any person, other than an
         employee of the Company, a person to whom disclosure is reasonably
         necessary or appropriate in connection with the performance by you of
         your duties as an executive of the Company or pursuant to any order or
         process of any court or regulatory agency, any material confidential
         information obtained by you while in the employ of the Company with
         respect to any of the Company's products, improvements, formulae,
         designs or styles, processes, customers, methods of distribution or
         methods of

                                                                         page 11


         manufacture; provided, however, that confidential information shall not
         include any information known generally to the public (other than as a
         result of unauthorized disclosure by you) or any information of a type
         not otherwise considered confidential by persons engaged in the same
         business or a business similar to that conducted by the Company.

     (B) INVENTIONS. Any and all inventions made, developed or created by you
         (whether at the request or suggestion of the Company or otherwise,
         whether alone or in conjunction with others, and whether during regular
         hours of work or otherwise) during the period of your employment by the
         Company, which may be directly or indirectly useful in, or relate to,
         the business of or tests being carried out by the Company or any of its
         subsidiaries or affiliates, will be promptly and fully disclosed by you
         to an appropriate executive officer of the Company and shall be the
         Company's exclusive property as against you, and you will promptly
         deliver to an appropriate executive officer of the Company all papers,
         drawings, models, data and other material relating to any invention
         made, developed or created by you as aforesaid.

         You will, upon the Company's request and without any payment
         therefor, execute any documents necessary or advisable in the
         opinion of the Company's counsel to direct issuance of patents to
         the Company with respect to such inventions as are to be the
         Company's exclusive property as against you under this subsection
         (b) or to vest in the Company title to such inventions as against
         the Executive, the expense of securing any patent, however, to be
         borne by the Company.

     (C) The foregoing provision of this Section 8 shall be binding upon the
         Executive's heirs, successors and legal representatives.

9.   SAVINGS CLAUSE.

     (A) The Deficit Reduction Act of 1984 added Section 280G to the Internal
         Revenue Code of 1954, as amended (the "Code"). Section 280G imposes a
         20% excise tax on excessive compensation received by, and denies a
         deduction to the corporation for the amount of excess compensation paid
         to, employees who are officers, shareholders, or highly compensated
         individuals as a result of a change in the ownership or effective
         control of the corporation or in the ownership of a substantial portion
         of the assets of the corporation. In general, payments to an individual
         that are contingent on a change in control will not be treated as
         excessive if such payments do not exceed three times the average annual
         compensation received by such individual over the five calendar years
         preceding the year in which the change in control occurred. The
         provisions in

                                                                         page 12


         subparagraph (B) of this paragraph 8 are designed to maximize the 
         amounts payable to you pursuant to this agreement or otherwise which 
         are contingent upon a change of control of the Company.

     (B) In the event that it is determined that any payment by the Company to
         or for your benefit (whether paid or payable pursuant to the terms of
         this agreement or otherwise) would be subject to the 20% tax pursuant
         to Section 4999 of the Code, then the aggregate present value of
         amounts payable to or for your benefit pursuant to this agreement (such
         payments pursuant to this agreement are hereinafter referred to as
         "Agreement Payments") shall be reduced to the Reduce Amount. For
         purposes of this subparagraph, the "Reduced Amount" shall be defined as
         an amount expressed in present value which maximizes the aggregate
         present value of Agreement Payments without causing any payments to be
         subject to the 20% tax pursuant to Section 4999 of the Code.
