      and in accordance with all of the terms and conditions of this
      Agreement.  Executive shall initially hold the position of Treasurer

      organizational development.

3.    Duties and Responsibilities.

	    the Company (presently in effect or as may be reasonably modified
	    or established hereafter) and be subject to the direction of the
	    Chief Executive Officer, the President, and the Board.

      (b)   Executive agrees to devote his entire normal working time,

	    of any Entity, be actively engaged in or concerned with any other
	    duties or pursuits (whether or not for gain, profit, or other

	    the Entities in which the investments are made or result in any
	    other conflict of Executive's interest or time.

      (c)   Executive shall use his best efforts, skills, and abilities to

4.    Term.

	    "Initial Term"), subject, however, to prior termination as
	    provided in Paragraphs 7 and 8 of this Agreement.  This Agreement
	    may be renewed or extended upon such terms and conditions as the
	    parties shall mutually agree to in a written instrument signed by

	    under any obligation to renew this Agreement.

      (b)   Executive's employment under this Agreement will not commence on
	    the date of the occurrence of a Change of Control if on the day
	    immediately prior to the Change of Control Executive is no longer
	    employed by the Company, unless Executive's employment by the
	    Company is terminated prior to the Change of Control at the request
	    of the individual or individuals or Entity or Entities acquiring
	    control of the Company.

5.    Compensation.
      During the Initial Term of Executive's employment under this Agreement,
      Executive shall be paid by the Company an annual salary of at least
      $160,000.00.  The salary paid to Executive may be reviewed by the Board
      and may be increased at the sole and unreviewable discretion of the
      Board, which shall take into account the earnings and overall
      productivity of the Company, available resources, the performance of
      Executive, the cost of living, and such other factors as it deems
      relevant.  The Board shall have no obligation to make any adjustments in
      the salary of Executive.  The salary to be paid to Executive under this
      Agreement shall be payable in equal monthly installments in accordance

	    pension, and health insurance plans in accordance with and subject
	    to the terms of such plans), as may be determined from time to
	    time by the Board.

      (b)   During the Initial Term of Executive's employment under this
	    Agreement, there shall be established an Incentive Bonus Program
	    for Fiscal Years 1994 and 1995.  In each such fiscal year,
	    Executive shall be eligible to earn up to $30,000.00 in bonuses,
	    calculated as follows:
	      (i)   if Executive meets or exceeds the fiscal-year new orders
		    target for Executive's Operating Group, as set forth in
		    the approved business plan, Executive shall earn
		    $10,000.00;
	     (ii)   if Executive meets or exceeds the fiscal-year contribution
		    margin target for Executive's Operating Group, as set
		    forth in the approved business plan, Executive shall earn
		    $10,000.00; and
	    (iii)   if Executive meets or exceeds the fiscal-year cash flow
		    target for Executive's Operating Group, as set forth in

		    $10,000.00.

	    Any Incentive Bonus earned during a fiscal year will be paid
	    during the first half of the following fiscal year and is subject
	    to reduction in accordance with subparagraph (c) immediately
	    below.  The three targets applicable to Executive for Fiscal Year
	    1994 are set forth in Exhibit A to this Agreement.  The three
	    targets applicable to Executive for Fiscal Year 1995 will be
	    established by the President of the Company, with the approval of
	    the Chief Executive Officer of the Company, after completion of
	    the Fiscal Year 1995 business plan and submission of the business
	    plan to the Board, and the President shall provide Executive a
	    written statement, in a form similar to Exhibit A, of the Fiscal
	    Year 1995 targets.

      (c)   If Executive is entitled to receive compensation under the
	    Company's Fiscal Year 1994 or 1995 Management Incentive Plan (or
	    such similar plan by whatever name it shall be known as), the
	    Incentive Bonus that Executive may be eligible for under
	    subparagraph (b) immediately above in Fiscal Year 1994 or 1995
	    shall be reduced as follows:
	      (i)   if the actual total compensation payable to Executive
		    under the Management Incentive Plan is less than or equal
		    to thirty (30) percent of Executive's annual salary, then
		    Executive shall receive one hundred (100) percent of the
		    total Incentive Bonus earned in accordance with
		    subparagraph (b) immediately above;
	     (ii)   if the actual total compensation payable to Executive
		    under the management Incentive Plan is greater than thirty
		    (30) percent but less than forty (40) percent of
		    Executive's annual salary, then Executive shall receive
		    only two-thirds of the total Incentive Bonus earned in
		    accordance with subparagraph (b) immediately above; or
	    (iii)   if the actual total compensation payable to Executive
		    under the Management Incentive Plan is equal to or greater
		    than forty (40) percent of Executive's annual salary, then
		    Executive shall receive only one-third of the total
		    Incentive Bonus earned in accordance with subparagraph (b)
		    immediately above.

7.    Termination of Employment by the Company for Death, Dis-ability, or
      Justifiable Cause, or by Executive Without Good Reason, or Upon
      Expiration of the Initial Term .
      (a)   The Company shall have the right to terminate the Executive's
	    employment under this Agreement upon the occurrence any one or
	    more of the following events:
	      (i)   the death of Executive (in which case said employment
		    terminates immediately upon death);
	     (ii)   the "disability" of Executive (as hereinafter defined); or
	    (iii)   the Board determines in its sole and unreview-able
		    discretion (acting reasonably and in good faith) that
		    "justifiable cause" (as hereinafter defined) exists for
		    the termination of Executive's employment.

	    Executive shall have the right to terminate Executive's employment
	    under this Agreement without "good reason" (as defined in
	    Paragraph 8 below) upon sixty (60) days' prior written notice to
	    the President of the Company.  No such termination by Executive
	    shall be effective unless that notice has been given.

	    Except as provided in subparagraph (b) immediately below, upon
	    termination of the employment of Executive under any of the
	    circumstances set forth in this subparagraph (a), Executive's
	    entitlement to further compensation or other benefits under
	    Paragraphs 5 and 6 of this Agreement shall immediately cease.

      (b)   For the purposes of this Agreement, the term "disability" shall
	    mean the inability of Executive, due to illness, accident, or any
	    other physical or mental incapacity, to perform his duties or
	    fulfill his obligations under this Agreement in a normal manner for
	    a period of any three (3) consecutive months or for a total of six
	    (6) months (whether or not consecutive) in any twelve (12) month
	    period during the Initial Term of this Agreement, it being
	    understood that, notwithstanding any such inability to perform his
	    duties, Executive shall be entitled to receive his compensation as
	    provided herein until the termination of his employment for
	    disability.  The Company shall provide Executive ten days' prior
	    written notice of any determination by the Board that Executive is
	    disabled.

      (c)   For purposes of this Agreement, "justifiable cause" for
	    termination by the Company of Executive's employment shall means
	    any one or more of the following:
	      (i)   any intentional breach by Executive of the performance of
		    any of his duties pursuant to this Agreement;
	     (ii)   any intentional or negligent disclosure by Executive to
		    any person or Entity (other than the Companies) and other
		    than in the ordinary course of business of any Confidential
		    Information of the Companies;
	    (iii)   any knowing violation or reckless disregard by Executive
		    of any law, governmental regulation, or judicial decree
		    which has caused substantial injury to the Companies,
		    financial or otherwise;
	      (iv)  Executive's interference with or
		    endeavor to entice away from the Companies any client or
		    customer, or solicitation of employment of any of the
		    Companies' officers, directors, employees, or agents;
	      (v)   Executive's conviction of a felony, as evidenced by a
		    binding and final judgment, order, or decree of a court of
		    competent jurisdiction, in effect after exhaustion or
		    lapse of all rights of appeal;
	     (vi)   the commission by Executive of any act of fraud, or
		    material act of malfeasance, disloyalty, or breach of
		    trust against the Companies;
	    (vii)   any attempt by Executive to secure any personal profit
		    (other than authorized compensation paid to Executive by
		    the Company) or convert any corporate opportunity to his
		    benefit in connection with the business of the Companies;
	    (viii)  any failure by Executive to devote his entire normal
		    working time to the affairs of the Companies;
	     (ix)   any activities of Executive that are determined to be
		    inimical to or contrary to the best interests of the
		    Companies; or
	      (x)   the conduct or involvement by Executive in any business
		    other than the businesses of the Companies.

	    The Company shall provide Executive ten (10) days' prior written
	    notice of termination for justifiable cause; provided, however,
	    that the Company shall not be required to furnish any such prior
	    written notice in the event that the Board reasonably determines
	    in its sole and unreviewable discretion that immediate termination
	    of Executive without such prior written notice is necessary to
	    protect the best interests of the Companies.  The written notice
	    shall set forth in reasonable detail the facts and circumstances
	    that are the basis for the termination for justifiable cause.

      (d)   If Executive is still employed under this Agreement at the end of
	    the Initial Term of this Agreement and if the parties hereto have
	    failed to reach a written agreement (signed by each of the parties
	    hereto) as to the continuation of Executive's employment,
	    Executive's employment under this Agreement will automatically
	    terminate upon expiration of the Initial Term.  In such case:
	      (i)   Executive's entitlement to further compensation or other
		    benefits under Paragraphs 5 and 6 of this Agreement shall
		    immediately cease upon expiration of the Initial Term; and
	     (ii)   such termination shall be deemed a triggering event
		    entitling Executive to severance pay under the Company's
		    severance pay policy, but in no event shall the severance
		    pay due and payable to Executive be less than a total of
		    six (6) weeks' salary; provided, however, that Executive
		    shall not be entitled to any severance pay if (A)
		    Executive is provided by the Company, at least sixty (60)
		    days prior to the expiration of the Initial Term, a
		    written offer to renew this Agreement for at least an
		    additional one (1) year and Executive does not accept in
		    writing that offer at least thirty (30) days prior to the
		    expiration of the Initial Term, or (B) Executive remains
		    employed by any of the Companies.

8.    Termination of Employment Under Other Circumstances.
      (a)   If (i) the Company terminates Executive's employment  under this
	    Agreement other than for death, "disability", or "justifiable
	    cause", or Executive terminates Executive's employment under this
	    Agreement for "good reason" (as hereinafter defined), and (ii)
	    Executive does not remain employed by any of the Companies,
	    Executive shall:
	      (i)   receive from the Company, within two (2) business days
		    after the termination, an amount in cash equal to the sum
		    of:
		    (A)   all salary due and payable to Executive as of the
			  date of termination;
		    (B)   pay for all accrued, but unused, vacation and sick
			  days through the date of termination;
		    (C)   all salary that would have been due and payable to
			  Executive over the remaining period of the Initial
			  Term of this Agreement if Executive's employment had
			  not been terminated, based on Executive's annual
			  salary in effect at the date of termination.  By way
			  of illustration, if Executive's annual salary at the
			  date of termination was $200,000.00 and the
			  termination occurred at the end of the seventh (7th)
			  month of the Initial Term, Executive would be
			  entitled to receive 17/24 x $400,000.00, or
			  $283,333.33; and
		    (D)   all severance pay due and payable to Executive under
			  the Company's severance pay policy, but in no event
			  less than a total of six (6) weeks' salary, it being
			  understood that a termination under this
			  subparagraph (a), whether by the Company or
			  Executive, shall be deemed a triggering event
			  entitling Executive to severance pay under the
			  Company's severance pay policy;
	     (ii)   receive from the Company all other benefits which
		    executive employees of the Company normally receive when
		    their employment is terminated by the Company without
		    "justifiable cause", which in no event shall be less than
		    the benefits such executive employees would have received
		    had their terminations occurred on the day immediately
		    preceding the Change of Control; and
	    (iii)   with respect to any stock options for shares of the
		    Company's stock that Executive has been or may be
		    hereafter awarded, and notwithstanding the terms of the
		    Long-Term Incentive Compensation Plans under which these
		    options were or may be hereafter granted, be entitled to
		    fully exercise said stock options at any time up to and
		    including the ninetieth day after the expiration of the
		    remaining period of the Initial Term of this Agreement.

      (b)   For purposes of this Agreement, "good reason" for Executive to
	    terminate Executive's employment under this Agreement shall mean
	    any one or more of the following:
	      (i)   both (A) without Executive's prior written consent, (1)
		    the assignment by the Company to Executive of duties and
		    responsibilities that are not at least substantially
		    equivalent to Executive's duties and responsibilities with
		    the Company immediately prior to the date of the Change of
		    Control, except in connection with the termination of
		    Executive's employment under this Agreement pursuant to
		    Paragraph 7 of this Agreement, or (2) the failure by the
		    Company to continue Executive in a position that is at
		    least substantially equivalent to the position held by
		    Executive with the Company immediately prior to the date
		    of the Change of Control, except in connection with the
		    termination of Executive's employment under this Agreement
		    pursuant to Paragraph 7 of this Agreement, and (B) the
		    continuance thereof for a period of twenty (20) days after
		    written notice thereof to the Company from Executive;
	     (ii)   a failure by the Company to pay, or a reduction by the
		    Company of, the annual salary required to be paid to
		    Executive under Paragraph 5 of this Agreement;
	    (iii)   a failure by the Company to pay any Incentive Bonus
		    required to be paid to Executive under Paragraph 6 of this
		    Agreement;
	     (iv)   a failure by the Company to provide Executive with (A) the
		    opportunity to participate, on terms no less favorable
		    than those in effect for other executives holding a
		    similar position, in all of the Company's benefit and
		    executive compensation plans and programs or their
		    equivalent or (B) all other fringe benefits, or their
		    equivalent, from time to time in effect for the benefit of
		    other executives holding a similar position;
	      (v)   without Executive's prior written consent, (A) the
		    relocation by the Company of the principal place of
		    Executive's employment to a location that is more than 100
		    miles from Executive's principal place of employment
		    immediately prior to the date of the Change of Control or
		    (B) the imposition by the Company of travel requirements
		    on Executive which are not substantially consistent with
		    the travel requirements applicable to Executive
		    immediately prior to the date of the Change of Control; or
	     (vi)   any breach of Paragraph 15 of this Agreement by the
		    Company.

      (c)   If the Company terminates Executive's employment under this
	    Agreement other than for death, "disability", or "justifiable
	    cause", the Company shall provide Executive at least ten (10)
	    days' prior written notice of that termination, and no such
	    termination shall be effective unless that notice has been given.
	    The notice shall set forth in reasonable detail the facts and
	    circumstances that are the basis for the termination.

      (d)   At least sixty (60) days prior to the termination by Executive of
	    Executive's employment under this Agreement for "good reason",
	    Executive shall provide the President of the Company with written
	    notice of Executive's intention to terminate Executive's
	    employment, and no such termination shall be effective unless that
	    notice has been given.  The notice shall set forth in reasonable
	    detail the facts and circumstances that are the basis for the
	    termination.

      (e)   If Executive's employment by the Company is terminated prior to a
	    Change of Control at the request of the individual or individuals
	    or Entity or Entities acquiring control of the Company, the
	    provisions of this Paragraph 8 shall apply as if a Change of
	    Control had occurred just prior to the date of termination.

9.    No Mitigation.
      Executive shall not be required to mitigate damages or the amount of any
      payment provided for under this Agreement by seeking other employment or
      otherwise, and payments and benefits due Executive under Paragraph 8(a)
      of this Agreement shall not be subject to offset in respect of any
      Claims which the Company has or may have against Executive.  Without
      limiting the generality of the foregoing, no payment otherwise required
      under this Agreement shall be reduced because of any payment received by

	  necessary detail for a complete understanding of the same) all
	  developments, know-how, discoveries, inventions, improvements,
	  concepts, ideas, writings, formulae, processes, and methods (whether
	  copyrightable, patentable, or otherwise) made, received, conceived,
	  acquired, or written by Executive (whether or not at the request of
	  or upon the suggestion of the Company) during the period of his
	  employment with any of the Companies, solely or jointly with others
	  (whether or not during working hours), in connection with or relating
	  to any activities of the Companies or any of their customers known
	  to him as a consequence of his employment (collectively referred to
	  as the "Subject Matter").

    (b)   Executive hereby assigns and transfers, and agrees to assign and
	  transfer, to the Company, all his right, title, and interest in and
	  to the Subject Matter.  Executive further agrees to deliver to the
	  Company any and all drawings, notes, specifications, and data
	  relating to the Subject Matter and to execute, acknowledge, and
	  deliver all such further papers, including applications for
	  copyrights, patents, and similar protected ownership rights, as may
	  be necessary to obtain copyrights, patents, and similar protected
	  ownership rights with respect to the Subject Matter in any and all
	  countries and to vest title to any such copyrights, patents, and
	  similar protected ownership rights in the Company.  Executive shall
	  assist the Company in obtaining such copyrights, patents, or similar
	  protected ownership rights during the period of his employment with
	  any of the Companies and any time thereafter and agrees to assist
	  the Company and to testify in its behalf in any prosecution or
	  litigation involving any of the Subject Matter during the period of
	  his employment with any of the Companies, and at any time
	  thereafter, in accordance with the provisions of subparagraph (c)
	  immediately below.

    (c)   At any time subsequent to the termination of Executive's employment
	  with any of the Companies or the expiration or termination of this
	  Agreement, if the Company requests in writing that Executive assist
	  the Company with respect to obtaining any patents, copyrights, or
	  similar protected ownership rights, or that Executive assist the
	  Company or testify in its behalf in connection with any prosecution
	  or litigation relating to the Subject Matter, the Company shall
	  reimburse Executive for Executive's reasonable out-of-pocket
	  expenses in connection with such assistance or testimony.  In the
	  event the Company shall request Executive's assistance or testimony
	  as set forth hereunder, the Company agrees to use its best efforts to
	  assure that such assistance or testimony will neither require a
	  major or unreasonable portion of Executive's time nor substantially
	  interfere with his then current employment or business activities.

11. Non-Disclosure of Confidential Information.
    (a)   Executive shall not during his employment with any of the Companies
	  (nor at any time following termination of such employment or
	  expiration or termination of this Agreement), directly or
	  indirectly, intentionally or negligently disclose to or permit to be
	  known by any person or Entity any Confidential Information acquired
	  by him during the course of or in connection with his employment by
	  any of the Companies relating to (i) the Companies, (ii) the
	  officers, directors, employees, or agents of the Companies, (iii)
	  any client or customer of the Companies, or (iv) any Entity owned or
	  controlled, directly or indirectly, by any of the foregoing, or in
	  which any of the foregoing has a beneficial interest.

    (b)   All Confidential Information, regardless of how recorded, relating
	  to the Companies shall be the exclusive property of the Companies,
	  and Executive shall use his best efforts to prevent any publication
	  or disclosure thereof.  Upon termination of Executive's employment
	  with any of the Companies or the expiration or termination of this
	  Agreement, all documents, records, reports, writings, and other
	  similar documents containing Confidential Information (including any
	  and all copies thereof) then in Executive's possession or control
	  shall be returned and left with the Company.

12.   Right to Injunctive and Other Relief.
      Executive recognizes that the services to be rendered by him to any of
      the Companies are of special, unique, unusual, extraordinary, and
      intellectual character, involving skill of the highest order, and that
      such services are of special and particular value, the loss of which
      cannot be adequately compensated for in damages.  Executive further
      agrees and declares that, because of his important role with the
      Companies to date, clients' or customers' association of Executive with
      the Companies, and the personal relationships Executive has with many of
      such clients or customers, Executive's services to the Companies are
      unique and extraordinary.  In the event of a breach of any provision of
      Paragraph 10 or 11 of this Agreement by Executive, the Companies shall
      be entitled to injunctive relief and any other legal or equitable
      remedies from a court of competent jurisdiction.  Executive acknowledges
      and agrees that any such breach will cause irreparable injury to the
      Companies and that money damages will not provide an adequate remedy to
      the Companies.  In any action for injunctive relief, Executive shall not
      be entitled to interpose a defense that the Companies have an adequate
      remedy in a court of law.  Executive agrees that the Companies may
      recover by appropriate action the amount of the actual damages caused
      the Companies by any failure, refusal, or neglect of Executive to
      perform his agreements, representations, and warranties contained in
      this Agreement.  The remedies provided in this Agreement shall be deemed
      cumulative and the exercise of one shall not preclude the exercise of
      any other remedy at law or in equity for the same event or any other
      event.

13.   No Conflicting Agreements.
      Executive represents and warrants that he is not a party to any
      agreement, contract, or understanding, whether of employment or
      otherwise, which would in any way restrict or prohibit him from
      undertaking or performing his employment and other obligations in
      accordance with the terms and conditions of this Agreement.  Executive
      further agrees to indemnify and hold harmless the Companies and their
      past and present officers, directors, employees, agents, owners,
      stockholders, representatives, and attorneys from and against and in
      respect of any and all Claims alleging that (a) Executive is so
      restricted or prohibited or (b) the Companies have committed a wrongful
      act in negotiating with, and employing the services of, Executive.

14.   Notices and Calendar Days.
      All notices, requests, demands, and other communications provided for by
      this Agreement shall be in writing and shall be personally delivered or
      mailed (by registered or certified mail, return receipt requested,
      postage prepaid) to the address of the party to whom intended as
      specified below or to such different address as such party may have
      fixed by a notice sent in accordance with this Paragraph.

      (a)   If to the Company, at:
	    Air & Water Technologies Corporation
	    P.O. Box 1500
	    Somerville, NJ 08876
	    Attention:  President
	    with a copy to:  General Counsel


      (b)   If to Executive, at:
	    30 Coventry Road
	    Mendham, NJ 07945

      Any such notices shall be effective upon receipt, if personally
      delivered, or three business days after mailing, if mailed.

      Unless otherwise expressly provided, all references in this Agreement to
      "days" mean "calendar days".

15.   Assignability and Binding Effect.
      (a)   This Agreement shall inure to the benefit of and shall be binding
	    upon the heirs, executors, administrators, successors, and legal
	    representatives of Executive, and shall inure to the benefit of
	    and be binding upon the Company and its successors, assigns, and
	    legal representatives, but the obligations of Executive may not be
	    delegated and Executive may not assign, transfer, pledge,
	    encumber, hypothecate, or otherwise dispose of this Agreement, or
	    any of his rights under this Agreement, and any such attempted
	    delegation or disposition shall be null and void and without
	    effect.  This Agreement shall also inure to the benefit of the
	    Companies and the Other Defendants (as defined in Paragraph 19
	    below) and their respective heirs, executors, administrators,
	    successors, assigns, and legal representatives.

      (b)   If the Company shall be merged into or consolidated with another
	    Entity, the provisions of this Agreement shall be binding upon and
	    inure to the benefit of the Entity surviving the merger or
	    resulting from the consolidation.  The Company shall require any
	    successor, whether direct or indirect, by purchase, merger,
	    consolidation, or otherwise, to all or substantially all of the
	    business or assets of the Company, by agreement in form and
	    substance satisfactory to Executive, expressly to assume and agree
	    to perform this Agreement in the same manner and to the same
	    extent that the Company would have been required to perform this
	    Agreement if no succession had taken place.  The provisions of
	    this Paragraph 15 shall continue to apply to each subsequent
	    employer of Executive bound by this Agreement in the event of any
	    merger, consolidation, or transfer of all or substantially all of
	    the business or assets of that subsequent employer.

16.   Complete Understanding.
      This Agreement constitutes the complete understanding between the
      parties with respect to the employment of Executive hereunder, and no
      statement, representation, warranty or covenant has been made by either
      party with respect thereto except as expressly set forth herein.  This
      Agreement shall not be altered, modified, amended, or terminated except
      by written instrument signed by each of the parties hereto.

17.   Governing Law.
      This Agreement and all provisions hereof shall be governed by and
      construed in accordance with the laws of the State of New Jersey.

18.   Severability.
      Should any part, term, or provision of this Agreement be declared or be
      determined by any court or tribunal of competent jurisdiction to be
      illegal, invalid, or unenforceable, the legality, validity, and
      enforceability of the remaining parts, terms, or provisions shall not be
      affected thereby, and said illegal, unenforceable, or invalid part,
      term, or provision shall be deemed not to be a part of this Agreement.

19.   Arbitration.
      (a)   Except as provided in subparagraph (b) immediately below, any and
	    all Claims arising out of or relating to (i) this Agreement, (ii)
	    any breach of any provision of this Agreement, (iii) Executive's
	    employment at any time with any of the Companies, and/or (iv) the
	    termination of Executive's employment with any of the Companies
	    shall be settled by arbitration.  Such arbitration proceeding
	    shall be conducted pursuant to the Employment Dispute Resolution
	    Rules of the American Arbitration Association ("AAA") then in
	    effect, by a single arbitrator, and shall be held in Somerset
	    County, New Jersey.  The arbitrator shall not have the power to
	    award punitive damages.  The cost of the arbitration proceeding
	    and the reasonable costs and attorneys' fees of the prevailing
	    party shall be paid by the non-prevailing party, with the dollar
	    amount of these costs and fees to be fixed by the arbitrator.  The
	    judgment upon the award rendered by the arbitrator may be entered
	    in any court having competent jurisdiction thereof.

      (b)   Nothing in subparagraph (a) immediately above shall be construed
	    or interpreted to preclude the Companies from filing suit in a
	    court of competent jurisdiction in order to enforce their rights
	    and remedies under Paragraphs 10, 11 and/or 12 of this Agreement.
	    In any such suit, the court is empowered to and shall resolve any
	    dispute as to whether the Claims asserted by any of the Companies
	    are within the scope of Paragraphs 10, 11, and/or 12 of this
	    Agreement, and the court shall not refer such dispute to
	    arbitration under subparagraph (a) immediately above.

      (c)   With respect to the Claims of Executive that are within the scope
	    of subparagraph (a) above, if Executive has the same, similar, or
	    related Claims against any of the Companies' employee benefit
	    plans, trusts, committees, or boards or against any past or
	    present officers, directors, employees, agents, owners,
	    stockholders, trustees, fiduciaries, administrators, sponsors,
	    representatives, or attorneys of the Companies or the Companies'
	    employee benefit plans, trusts, committees, or boards
	    (collectively referred to as the "Other Defendants"), and if
	    Executive seeks to litigate such Claims against the Other
	    Defendants in a civil action or any other proceeding (including
	    before an administrative agency), Executive agrees that any or all
	    of said Other Defendants may compel Executive to arbitrate his
	    Claims against them pursuant to the terms of this Paragraph 19.

      (d)   The arbitrator selected by the parties pursuant to the AAA rules
	    shall have expertise in private industry employee relations and
	    shall hear and determine the case promptly.  The burden of
	    persuasion shall at all times be upon the party seeking relief.

      (e)   In the event Executive files suit in a court of competent
	    jurisdiction and asserts that certain Claims are not subject to
	    arbitration under this Paragraph 19 because of the limitation on
	    the power of the arbitrator to award punitive damages (the
	    "Limitation"), the parties agree that they will request the court
	    to resolve that legal issue on an expedited basis, and if the
	    court rules in favor of Executive on the Limitation issue, the
	    parties agree as follows:

	      (i)   the arbitration shall proceed as if this Paragraph 19 did
		    not contain such Limitation;
	     (ii)   the parties will request the court to enter judgment in
		    favor of  Executive on the Limitation issue, at which time
		    the Company may appeal that ruling;
	    (iii)   in the event the arbitrator determines that Executive is
		    entitled to punitive damages, the punitive damages aspect
		    of the arbitrator's award will be stayed pending the
		    exhaustion or lapse of all rights of appeal of the Company
		    under subparagraph (e)(ii) immediately above; and
	     (iv)   in the event an appellate court rules in favor of the
		    Company on the Limitation issue, the arbitrator shall
		    vacate the award of punitive damages.
	    The procedures set forth in this subparagraph (e) shall also apply
	    in the event Executive seeks relief in some other tribunal, such
	    as an administrative agency, and the Company files a civil action
	    to compel arbitration.

20.   Waiver.
      It is agreed that a waiver by either party of a breach of any provision
      of this Agreement shall neither operate nor be construed as a waiver of
      any subsequent breach hereof, or as a waiver of a breach of any other
      provision.

21.   Survival.
      All representations and warranties herein shall survive any termination
      of Executive's employment or termination or expiration of this
      Agreement, and the termination of Executive's employment or the
      termination or expiration of this Agreement shall not affect the
      enforceability of  Paragraphs 10, 11, 12, 13, and 19 of this Agreement,
      which Paragraphs shall survive the termination or expiration of this
      Agreement or the termination of Executive's employment.

22.   Other Documents.
      The parties agree to execute and deliver all such further instruments
      and take such other and further action as may be reasonably necessary or
      appropriate to carry out the provisions of this Agreement.

23.   Paragraph Headings.
      The paragraph headings contained in this Agreement are for reference
      purposes only and shall not affect in any way the meaning or
      interpretations of this Agreement.
