                                 EXHIBIT 10.86

                              INDEMNITY AGREEMENT
                             ---------------------

         THIS AGREEMENT, made and entered into on and as of this 16th day of
June, 1997, (the "Agreement"), is by and between Brown & Sharpe Manufacturing
Company, a Delaware corporation, (the "Company", which term shall include any
one or more of its subsidiaries where appropriate), and Edward D. DiLuigi (the
"Indemnitee"):


                                    RECITALS

         WHEREAS, highly competent persons are becoming more reluctant to serve
publicly-held corporations as directors or in other capacities unless they are
provided with adequate protection through insurance or adequate indemnification
against inordinate risks of claims and actions against them arising out of their
service to and activities on behalf of the corporation; and,

         WHEREAS, the current impracticability of obtaining adequate insurance
and the uncertainties relating to indemnification have increased the difficulty
of attracting and retaining such persons; and,

         WHEREAS, the Board of Directors of the Company (the "Board") has
determined that the difficulty in attracting and retaining such persons is
detrimental to the best interests of the Company's shareholders and that the
Company should act to assure such persons that there will be increased certainty
of such protection in the future; and,

         WHEREAS, it is reasonable, prudent and necessary for the Company
contractually to obligate itself to indemnify such persons to the fullest extent
permitted by applicable law so that they will serve or continue to serve the
Company free from undue concern that they will not be so indemnified; and,

         WHEREAS, Indemnitee is willing to serve, continue to serve and/or to
take on additional service for or on behalf of the Company on the condition that
he be so indemnified;

         NOW, THEREFORE, in consideration of the premises and the covenants
contained herein, the Company and Indemnitee do hereby covenant and agree as
follows:

         1.   Services by Indemnitee. Indemnitee agrees to serve or continue to
serve as an officer of the Company. This Agreement shall not impose any
obligation on the Indemnitee or the Company to continue the Indemnitee's
position with the Company beyond any period otherwise applicable.

         2.   General. The Company shall indemnify and shall advance Expenses
(as hereinafter defined) to Indemnitee as provided in this Agreement and to the
fullest extent permitted by law.

         3.   Proceedings Other Than Proceedings by or in the Right of the
Company. Indemnitee shall be entitled to the rights of indemnification provided
in this Section 3 if, by reason of his Corporate Status, (as hereinafter
defined), he is, or is threatened to be made, a party to any threatened,
pending, or completed Proceeding (as hereinafter defined), other than a
Proceeding by or in the right of the Company. Pursuant to this Section 3,
Indemnitee shall be indemnified against expenses, judgments, penalties, fines
and amounts paid in settlement actually and reasonably incurred by him or on his
behalf in connection with such Proceeding or any claim, issue or matter therein,
if he acted in good faith and in a manner he reasonably believed to be in or not
opposed to the best interests of the Company, and, with respect to any criminal
Proceeding, had no reasonable cause to believe his conduct was unlawful.

         4.   Proceedings by or in the Right of the Company. Indemnitee shall be
entitled to the rights of indemnification provided in this Section 4, if, by
reason of his Corporate Status, he is, or is threatened to


<PAGE>

be made, a party to any threatened, pending or completed Proceeding brought by
or in the right of the Company to procure a judgment in its favor. Pursuant to
this Section, Indemnitee shall be indemnified against Expenses actually and
reasonably incurred by him or on his behalf in connection with such Proceeding
if he acted in good faith and in a manner he reasonably believed to be in or not
opposed to the best interests of the Company. Notwithstanding the foregoing, no
indemnification against such Expenses shall be made in respect of any claim,
issue or matter as to which Indemnitee shall have been adjudged to be liable to
the Company if such indemnification is not permitted by Delaware law; provided,
however, that indemnification against Expenses shall nevertheless be made by the
Company in such event to the extent that the Court of Chancery of the State of
Delaware, or the court in which such Proceeding shall have been brought or is
pending, shall determine.


         5. Indemnification for Expenses of a Party who is Wholly or Partly
Successful. Notwithstanding any other provision of this Agreement, to the extent
that Indemnitee is, by reason of his Corporate Status, a party to and is
successful, on the merits or otherwise, in any Proceeding, he shall be
indemnified against all Expenses actually and reasonably incurred by him or on
his behalf in connection therewith. If Indemnitee is not wholly successful in
such Proceeding but is successful, on the merits or otherwise, as to one or more
but less than all claims, issues or matters in such Proceeding, the Company
shall indemnify Indemnitee against all Expenses actually and reasonably incurred
by him or on his behalf in connection with each successfully resolved claim,
issue or matter. For purposes of this Section and without limitation, the
termination of any claim, issue or matter in such a Proceeding by dismissal or
withdrawal, with or without prejudice, shall be deemed to be a successful result
as to such claim, issue or matter.

         6. Advance of Expenses. The Company shall advance all reasonable
Expenses incurred by or on behalf of Indemnitee in connection with any
Proceeding within twenty days after the receipt by the Company of a statement or
statements from Indemnitee requesting such advance or advances from time to
time, whether prior to or after final disposition of such Proceeding. Such
statement or statements shall reasonably evidence the Expenses incurred by
Indemnitee and shall include or be preceded or accompanied by an undertaking by
or on behalf of Indemnitee to repay any Expenses advanced if it shall ultimately
be determined that Indemnitee is not entitled to be indemnified against such
Expenses.

         7.   Procedure for Determination of Entitlement to Indemnification.

              (a) To obtain indemnification under this Agreement, Indemnitee
shall submit to the Company a written request, including therein or therewith
such documentation and information as is reasonably available to Indemnitee and
is reasonably necessary to determine whether and to what extent Indemnitee is
entitled to indemnification. The Secretary of the Company shall, promptly upon
receipt of such a request for indemnification, advise the Board of Directors in
writing that Indemnitee has requested indemnification.

              (b) Upon written request by Indemnitee for indemnification
pursuant to Section 7(a) hereof, a determination, if required by applicable law,
with respect to Indemnitee's entitlement thereto shall be made in the specific
case: (i) if a Change in Control (as hereinafter defined) shall have occurred,
by Independent Counsel (as hereinafter defined) in a written opinion to the
Board of Directors, a copy of which shall be delivered to Indemnitee (unless
Indemnitee shall request that such determination be made by the Board of
Directors or the shareholders, in which case the determination shall be made in
the manner provided below in clauses (ii) or (iii); (ii) if a Change of Control
shall not have occurred, (A) by the Board of Directors by a majority vote of a
quorum consisting of Disinterested Directors (as hereinafter defined), or (B) if
a quorum of the Board of Directors consisting of Disinterested Directors is not
obtainable or, even if obtainable, such quorum of Disinterested Directors so
directs, by Independent Counsel in a written opinion to the Board of Directors,
a copy of which shall be delivered to Indemnitee or (C) by the shareholders of
the Company; or (iii) as provided in Section 8(b) of this Agreement; and, if it
is so determined that Indemnitee is entitled to indemnification, payment to
Indemnitee shall be made within ten (10) days after such determination.
Indemnitee shall cooperate with the person, persons or entity making such
determination with respect to Indemnitee's entitlement to indemnification,
including providing to such person, persons or entity upon reasonable advance
request any documentation or
<PAGE>

information which is not privileged or otherwise protected from disclosure and
which is reasonably available to Indemnitee and reasonably necessary to such
determination. Any costs of expenses (including attorneys' fees and
disbursements) incurred by Indemnitee in so cooperating shall be borne by the
Company (irrespective of the determination), and the Company hereby indemnifies
and agrees to hold Indemnitee harmless therefrom.

              (c) In the event the determination of entitlement to
indemnification is to be made by Independent Counsel pursuant to Section 7(b) of
this Agreement, the Independent Counsel shall be selected as provided in this
Section 7(c). If a Change of Control shall not have occurred, the Independent
Counsel shall be selected by the Board of Directors, and the Company shall give
written notice to Indemnitee advising him of the identity of the Independent
Counsel so selected. If a Change of Control shall have occurred, the Independent
Counsel shall be selected by Indemnitee (unless Indemnitee shall request that
such selection be made by the Board of Directors, in which event the preceding
sentence shall apply), and Indemnitee shall give written notice to the Company
advising it of the identity of the Independent Counsel so selected. In either
event, Indemnitee or the Company, as the case may be, may within 7 days after
such written notice of selection shall have been given, deliver to the Company
or to Indemnitee, as the case may be, a written objection to such selection.
Such objection may be asserted only on the ground that the Independent Counsel
so selected does not meet the requirements of "Independent Counsel" as defined
in Section 13 of this Agreement, and the objection shall set forth with
particularity the factual basis of such assertion. If such written objection is
made, the Independent Counsel so selected may not serve as Independent Counsel
unless and until a court has determined that such objection is without merit.
If, within 20 days after submission by Indemnitee of a written request for
indemnification pursuant to Section 7(a) hereof, no Independent Counsel shall
have been selected or if selected, shall have been objected to, in accordance
with this Section 7(c), either the Company or Indemnitee may petition the Court
of Chancery of the State of Delaware or other court of competent jurisdiction
for resolution of any objection which shall have been made by the Company or
Indemnitee to the other's selection of Independent Counsel and/or for the
appointment as Independent Counsel of a person selected by the Court or by such
other person as the Court shall designate, and the person with respect to whom
an objection is favorably resolved or the person so appointed shall act as
Independent Counsel under Section 7(b) hereof. The Company shall pay any and all
reasonable fees and expenses of Independent Counsel incurred by such Independent
Counsel in connection with acting pursuant to Section 7(b) hereof, and the
Company shall pay all reasonable fees and expenses incident to the procedures of
this Section 7(c), regardless of the manner in which such Independent Counsel
was selected or appointed. Upon the due commencement of any judicial proceeding
or arbitration pursuant to Section 9(a)(iii) of this Agreement, Independent
Counsel shall be discharged and relieved of any further responsibility in such
capacity (subject to the applicable standards of professional conduct then
prevailing).

         8.   Presumptions and Effect of Certain Proceedings.

              (a) If a Change of Control shall have occurred in making a
determination with respect to entitlement to indemnification hereunder, the
person, persons or entity making such determination shall presume that
Indemnitee is entitled to indemnification under this Agreement if Indemnitee has
submitted a request for indemnification in accordance with Section 7(a) of this
Agreement, and the Company shall have the burden of proof to overcome that
presumption in connection with the making by any person, persons or entity of
any determination contrary to that presumption.

              (b) If the person, persons or entity empowered or selected under
Section 7 of this Agreement to determine whether Indemnitee is entitled to
indemnification shall not have made such determination within 60 days after
receipt by the Company of the request therefor, the requisite determination of
entitlement to indemnification shall be deemed to have been made, and Indemnitee
shall be entitled to such indemnification, absent (i) a misstatement by
Indemnitee of a material fact, or an omission of a material fact necessary to
make Indemnitee's statement not materially misleading, in connection with the
request for indemnification, or (ii) a prohibition of such indemnification under
applicable law; provided, however, that such 60-day period may be extended for a
reasonable time, not to exceed an additional 30 days, if the person, persons or
entity making the determination with respect to
<PAGE>

entitlement to indemnification in good faith requires such additional time for
the obtaining or evaluating of documentation and/or information relating
thereto; and provided, further, that the foregoing provisions of this Section
8(b) shall not apply (i) if the determination of entitlement to indemnification
is to be made by the shareholders pursuant to Section 7(b) of this Agreement and
if (A) within 15 days after receipt by the Company of the request for such
determination the Board of Directors has resolved to submit such determination
to the shareholders for their consideration at an annual meeting thereof to be
held within 75 days after such receipt and such determination is made thereat,
(B) a special meeting of shareholders is called within 15 days after such
receipt for the purpose of making such determination, such meeting is held for
such purpose within 60 days after having been so called and such determination
is made thereat, or (ii) if the determination of entitlement to indemnification
is to be made by Independent Counsel pursuant to Section 7(b) of this Agreement.

              (c) The termination of any Proceeding or of any claim, issue or
matter therein by judgment, order, settlement or conviction, or upon a plea of
nolo contendere or its equivalent, shall not (except as otherwise expressly
provided in this Agreement) of itself adversely affect the right of Indemnitee
to indemnification or create a presumption that Indemnitee did not act in good
faith and in a manner which he reasonably believed to be in or not opposed to
the best interests of the Company or, with respect to any criminal Proceeding,
that Indemnitee had reasonable cause to believe that his conduct was unlawful.

         9.   Remedies of Indemnitee.

              (a) In the event that (i) a determination is made pursuant to
Section 7 of this Agreement that Indemnitee is not entitled to indemnification
under this Agreement, (ii) advancement of Expenses is not timely made pursuant
to Section 6 of this Agreement, (iii) the determination of entitlement to
indemnification is to be made by Independent Counsel pursuant to Section 7(b) of
this Agreement and such determination shall not have been made and delivered in
a written opinion within 90 days after receipt by the Company of the request for
indemnification, (iv) payment of indemnification is not made pursuant to Section
5 of this Agreement within ten (10) days after receipt by the Company of a
written request therefor, or (v) payment of indemnification is not made within
ten (10) days after a determination has been made that Indemnitee is entitled to
indemnification or such determination is deemed to have been made pursuant to
Section 8 of this Agreement, Indemnitee shall be entitled to an adjudication in
an appropriate court of the State of Delaware, or in any other court of
competent jurisdiction, of his entitlement to such indemnification or
advancement of Expenses. Alternatively, Indemnitee, at his option, may seek an
award in arbitration to be conducted by a single arbitrator pursuant to the
rules of the American Arbitration Association. Indemnitee shall commence such
proceeding seeking an adjudication or an award in arbitration within 180 days
following the date on which Indemnitee first has the right to commence such
proceeding pursuant to this Section 9(a). The Company shall not oppose
Indemnitee's right to seek any such adjudication or award in arbitration.

              (b) In the event that a determination shall have been made
pursuant to Section 7 of this Agreement that Indemnitee is not entitled to
indemnification, any judicial proceeding or arbitration commenced pursuant to
this Section 9 shall be conducted in all respects as a de novo trial, or
arbitration, on the merits and Indemnitee shall not be prejudiced by reason of
that adverse determination. If a Change of Control shall have occurred in any
judicial proceeding or arbitration commenced pursuant to this Section 9, the
Company shall have the burden of proving that Indemnitee is not entitled to
indemnification or advancement of Expenses, as the case may be.

              (c) If a determination shall have been made or deemed to have been
made pursuant to Section 7 or 8 of this Agreement that Indemnitee is entitled to
indemnification, the Company shall be bound by such determination in any
judicial proceeding or arbitration commenced pursuant to this Section 9, absent
(i) a misstatement by Indemnitee of a material fact, or an omission of a
material fact necessary to make Indemnitee's statement not materially
misleading, in connection with the request for indemnification, or (ii) a
prohibition of such indemnification under applicable law.

              (d) The Company shall be precluded from asserting in any judicial
proceedings or arbitration commenced pursuant to this Section 9 that the
procedures and presumptions of this Agreement are not
<PAGE>

valid, binding and enforceable and shall stipulate in any such court or before
any such arbitrator that the Company is bound by all the provisions of this
Agreement.

              (e) In the event that Indemnitee, pursuant to this Section 9,
seeks a judicial adjudication of or an award in arbitration to enforce his
rights under, or to recover damages for breach of, this Agreement, Indemnitee
shall be entitled to recover from the Company, and shall be indemnified by the
Company against, any and all expenses (of the types described in the definition
of Expenses in Section 13 of this Agreement) actually and reasonably incurred by
him in such judicial adjudication or arbitration, but only if he prevails
therein. If it shall be determined in said judicial adjudication or arbitration
that Indemnitee is entitled to receive part but not all of the indemnification
or advancement of expenses sought, the expenses incurred by Indemnitee in
connection with such judicial adjudication or arbitration shall be appropriately
prorated.

         10. Security. To the extent requested by the Indemnitee and approved by
the Board, the Company may at any time and from time to time provide security to
the Indemnitee for the Company's obligations hereunder through an irrevocable
bank line of credit, funded trust, or other collateral. Any such security, once
provided to the Indemnitee, may not be revoked or released without the prior
written consent of Indemnitee.

         11.  Non-Exclusivity; Duration of Agreement, Insurance; Subrogation.

              (a) The rights of indemnification and to receive advancement of
Expenses as provided by this Agreement shall not be deemed exclusive of any
other rights to which Indemnitee may at any time be entitled under applicable
law, the Company's certificate of incorporation or by-laws, any other agreement,
a vote of shareholders or a resolution of directors, or otherwise. This
Agreement shall continue until and terminate upon the later of: (a) 10 years
after the date that Indemnitee shall have ceased to serve as a director or
officer of the Company or fiduciary of any other corporation, partnership, joint
venture, trust, employee benefit plan or other enterprise on which Indemnitee
served at the request of the Company; or (b) the final termination of all
pending Proceedings in respect of which Indemnitee is granted rights of
indemnification or advancement of expenses hereunder and of any proceeding
commenced by Indemnitee pursuant to Section 9 of this Agreement relating
thereto. This Agreement shall be binding upon the Company and its successors and
assigns and shall inure to the benefit of Indemnitee and his heirs, executors
and administrators.

              (b) To the extent that the Company maintains an insurance policy
or policies providing liability insurance for directors and officers of the
Company or fiduciaries of any other corporation, partnership, joint venture,
trust, employee benefit plan or other enterprise which such person serves at the
request of the Company, Indemnitee shall be covered by such policy or policies
in accordance with its or their terms to the maximum extent of the coverage
available for any such director or officer under such policy or policies.

              (c) In the event of any payment under this Agreement, the Company
shall be subrogated to the extent of such payment to all of the rights of
recovery of Indemnitee who shall execute all papers required and take all action
necessary to secure such rights including execution of such documents as are
necessary to enable the Company to bring suit to enforce such rights.
<PAGE>

              (d) The Company shall not be liable under this Agreement to make
any payment of amounts otherwise indemnifiable hereunder if and to the extent
that Indemnitee has otherwise actually received such payment under any insurance
policy, contract, agreement or otherwise.

         12. Severability. If any provision or provisions of this Agreement
shall be held to be invalid, illegal or unenforceable for any reason whatsoever:
(a) the validity, legality and enforceability of the remaining provisions of
this Agreement (including, without limitation, each portion of any Section of
this Agreement containing any such provision held to be invalid, illegal or
unenforceable, that is not itself invalid, illegal or unenforceable) shall not
in any way be affected or impaired thereby; and (b) to the fullest extent
possible, the provisions of this Agreement (including, without limitation, each
portion of any Section of this Agreement containing any such provision held to
be invalid, illegal or unenforceable, that is not itself invalid, illegal or
unenforceable) shall be construed so as to give effect to the intent manifested
by the provision held invalid, illegal or unenforceable.

         13. Exception to Right of Indemnification or Advancement of Expenses.
Notwithstanding any other provision of this Agreement, Indemnitee shall not be
entitled to indemnification or advancement of Expenses under this Agreement with
respect to any Proceeding, or any claim therein, brought or made by him against
the Company.

         14.  Definitions.  For purposes of this Agreement:

              (a) "Change in Control" means a change in control of the Company
of a nature that would be required to be reported in response to Item 5(f) of
Schedule 14A of Regulation 14A (or in response to any similar item on any
similar schedule or form) promulgated under the Securities Exchange Act of 1934
(the "Act"), whether or not the Company is then subject to such reporting
requirement; provided, however, that, without limitation, such a Change in
Control shall be deemed to have occurred if (i) any "person" (as such term is
used in Sections 13(d) and 14(d) of the Act) is or becomes the "beneficial
owner" (as defined in Rule 13d-3 under the Act), directly or indirectly, of
securities of the Company representing 20% or more of the combined voting power
of the Company's then outstanding securities without the prior approval of at
least two-thirds of the members of the Board of Directors in office immediately
prior to such person attaining such percentage interest; (ii) the Company is a
party to a merger, consolidation, sale of assets or other reorganization, or a
proxy contest, as a consequence of which members of the Board of Directors in
office immediately prior to such transaction or event constitute less than a
majority of the Board of Directors thereafter; or (iii) during any period of two
consecutive years, individuals who at the beginning of such period constituted
the Board of Directors (including for this purpose any new director whose
election or nomination for election by the Company's shareholders was approved
by a vote of at least two-thirds of the directors then still in office who were
directors at the beginning of such period) cease for any reason to constitute at
least a majority of the Board of Directors.

              (b) "Corporate Status" describes the status of a person who is or
was or has agreed to become a director of the Company, or is or was an officer
or fiduciary of the Company or of any other corporation, partnership, joint
venture, trust, employee benefit plan or other enterprise which such person is
or was serving at the request of the Company.

              (c) "Disinterested Directors" means a director of the Company who
is not and was not a party to the Proceeding in respect of which indemnification
is sought by Indemnitee.

              (d) "Expenses" shall include all reasonable attorneys' fees,
retainers, court costs, transcript costs, fees of experts, travel expenses,
duplicating costs, printing and binding costs, telephone charges, postage,
delivery service fees, and all other disbursements or expenses of the types
customarily incurred in connection with prosecuting, defending, preparing to
prosecute or defend or investigating a Proceeding.

              (e) "Independent Counsel" means a law firm, or a member of a law
firm, that is experienced in matters of corporation law and neither presently
is, nor in the past five years has been, retained to
<PAGE>

represent: (i) the Company or Indemnitee in any matter material to either such
party, or (ii) any other party to the Proceeding giving rise to a claim for
indemnification hereunder. Notwithstanding the foregoing, the term "Independent
Counsel" shall not include any person who, under the applicable standards of
professional conduct then prevailing, would have a conflict of interest in
representing either the Company or Indemnitee in an action to determine
Indemnitee's rights under this Agreement.

              (f) "Proceeding" includes any action, suit, arbitration, alternate
dispute resolution mechanism, investigation, administrative hearing or any other
proceeding, whether civil, criminal, administrative or investigative, arising on
or after the date of this Agreement (and regardless of when the Indemnitee's act
or failure to act occurred), except one initiated by an Indemnitee pursuant to
Section 9 of this Agreement to enforce his rights under this Agreement.

         15.  Headings. The headings of the paragraphs of this Agreement are
inserted for convenience only and shall not be deemed to constitute part of this
Agreement or to affect the construction thereof.

         16. Modification and Waiver. This Agreement may be amended from time to
time to reflect changes in Delaware law or for other reasons. No supplement,
modification or amendment of this Agreement shall be binding unless executed in
writing by both of the parties hereto. No waiver of any of the provisions of
this Agreement shall be deemed or shall constitute a waiver of any other
provision hereof (whether or not similar) nor shall such waiver constitute a
continuing waiver.

         17. Notice by Indemnitee. Indemnitee agrees promptly to notify the
Company in writing upon being served with any summons, citation, subpoena,
complaint, indictment, information or other document relating to any Proceeding
or matter which may be subject to indemnification or advancement of Expenses
covered hereunder, provided, however, that the failure to give any such notice
shall not disqualify the Indemnitee from indemnification hereunder.

         18. Notices. All notices, requests, demands and other communications
hereunder shall be in writing and shall be deemed to have been duly given if (i)
delivered by hand and receipted for by the party to whom said notice or other
communication shall have been directed, or (ii) mailed by certified or
