and to perform its obligations hereunder and thereunder.  The execution,
delivery and performance of this Agreement and all other agreements and
certificates referred to in, or contemplated by, this Agreement have been duly
authorized by all necessary corporate action on the part of the Company.  This
Agreement has been duly executed and delivered by the Company and is (and such
other agreements and certificates, when executed and delivered, will be) the
valid and binding obligations of the Company enforceable against the Company in
accordance with its terms, except as such enforceability may be limited by
applicable bankruptcy, moratorium, insolvency, reorganization or other similar
laws now or hereafter in effect relating to or affecting creditors' rights
generally and general equitable principles (whether considered in a proceeding
in equity or at law).

          5.8.  Tax Matters.  The Company has timely filed all Tax Returns (as
                -----------
defined in Section 11.1 hereof) that it has been required to file through the
date hereof, and has paid in full all Taxes (as defined in Section 11.1 hereof)

Taxes reflected on the December 31, 1999 Balance Sheet are adequate to cover
accrued and unpaid Taxes of the Company for all periods ending on or before

December 31, 1999 and, to the Company's knowledge (as defined in Section 11.1
hereof), nothing has occurred subsequent to that date to make such provisions
inadequate.  The Company has established and is maintaining current accruals
that are accurately reflected in the books and records of the Company and are
adequate for the payment of any Taxes incurred but not yet due and payable with
respect to the property and operations of the Company through the date hereof.
No waivers or extensions of any applicable statute of limitations for the
assessment or collection of Taxes with respect to any Tax Returns of the Company
are currently in effect or are currently proposed.  The Company has collected or
withheld and paid over to the proper governmental or regulatory bodies all Tax-
related amounts required to be so collected or withheld and paid over under all
applicable Laws.  No action, suit, proceeding, investigation, audit, claim or
assessment is presently pending or, to the Company's knowledge, threatened with
regard to any Taxes that relate to the Company for which the Company is or could
reasonably be expected to be liable.  There is no unresolved written claim by a
taxing authority in any jurisdiction where the Company does not anticipate to
file Tax Returns that it is or could reasonably be expected to be subject to
taxation by such jurisdiction.  There are no Liens for Taxes (other than for
Taxes not yet due and payable) upon any assets or property of the Company.  Each
Purchaser hereby acknowledges that the foregoing representations and warranties
made in this Section 5.8 do not apply in respect of Accurate Components Inc.

or assets; and (ii) at no time has filed a consent to the application of Section
341(f)(2) of the Code to any property or assets held, acquired or to be acquired

             -------------
No violations have occurred in respect of any

          10.   INDEMNIFICATION.
                ---------------

          10.1. Obligation of the Company to Indemnify.  Subject to the
limitations and expiration dates contained in Section 9 hereof and to this
Section 10, the Company shall indemnify, defend and hold harmless the Purchasers
and each of their respective directors, officers, equityholders, affiliates,
successors and permitted assigns from and against, and shall pay and/or
reimburse the foregoing persons for, any and all losses, liabilities, claims,
obligations, damages, costs and expenses (including reasonable attorneys' fees
and disbursements and other costs incurred or sustained by an Indemnitee (as
defined below) in connection with the defense or prosecution of any claim,
action or proceeding) (collectively, "Losses") relating to or arising out of the
breach of any representation, warranty, covenant or agreement of the Company
contained in this Agreement.

          10.2.  [intentionally omitted]

          10.3.  Notice to Indemnifying Party.  If a Purchaser (or any related
                 ----------------------------
indemnitees) receives notice of any claim or the commencement of any action or
proceeding (the "Indemnitee") with respect to which the Company is obligated to
provide indemnification (the "Indemnifying Party") pursuant to Section 10.1
hereof, the Indemnitee shall give the Indemnifying Party written notice thereof
within a reasonable period of time following the Indemnitee's receipt of such
notice.  Such notice shall describe the claim in reasonable detail and shall
indicate the amount (estimated if necessary) of the Losses that have been or may
be sustained by the Indemnitee.  The Indemnifying Party may, subject to the
other provisions of this Section 10.3, compromise or defend, at such
Indemnifying Party's own expense and by such Indemnifying Party's own counsel,
any such matter involving the asserted liability of the Indemnitee in respect of
a third-party claim.  If the Indemnifying Party elects to compromise or defend
such asserted liability, it shall within thirty (30) days (or sooner, if the
nature of the asserted liability so requires) notify the Indemnitee of its
intent to do so, and the Indemnitee, shall reasonably cooperate, at the request
and reasonable expense of the Indemnifying Party, in the compromise of, or
defense against, such asserted liability.  The Indemnifying Party will not be
released from any obligation to indemnify the Indemnitee hereunder with respect
to a claim without the  prior written consent of the Indemnitee, unless the
Indemnifying Party delivers to the Indemnitee a duly executed agreement settling
or compromising such claim with no monetary liability to or injunctive relief
against the Indemnitee and a complete release of the Indemnitee with respect
thereto.  The Indemnifying Party shall have the right, except as otherwise
provided below in this Section 10.3, to conduct and control the defense of any
third-party claim made for which it has been provided notice hereunder.  All
reasonable costs and fees incurred with respect to any such claim will be borne
by the Indemnifying Party.  The Indemnitee will have the right to participate,
but not control, at its own expense, the defense or settlement of any such
claim; provided, that if the Indemnitee  and the Indemnifying Party shall have
       --------
conflicting claims or defenses, the Indemnifying Party shall not have control of
such conflicting claims or defenses and the Indemnitee (and all related
Indemnitees) shall be entitled to appoint a separate counsel for such claims and
defenses at the reasonable cost and expense of the Indemnifying Party.  If the
Indemnifying Party chooses to defend any claim, the Indemnitee

                                      15
<PAGE>

shall make available to the Indemnifying Party any books, records or other
documents within its control that are reasonably required for such defense.

          10.4.  Limitations on Indemnification.  (a) The Company shall be
                 ------------------------------
obligated to indemnify any Indemnitee(s) pursuant to Section 10.1 hereof with
respect to any Losses incurred by such Indemnitee(s) only if and to the extent
that the aggregate amount of Losses for claims made by all Indemnitees shall
exceed $200,000, in which case only the excess over $200,000 shall be subject to
indemnification hereunder.  The foregoing $200,000 minimum requirement shall not
apply in respect of claims or actions arising out of or resulting from
breach(es) of Sections 5.1, 5.2, 5.3, 5.4, 5.7, 5.10 and 5.21 hereof.

          (b) In no event shall the Company or the Purchasers, as the case may
be, be liable to any Indemnitee(s) hereunder for special, consequential,
indirect, incidental or punitive damages or penalties.

          (c) Notwithstanding anything to the contrary contained in this
Agreement, the aggregate liability of the Company for any and all Losses
incurred by the Purchasers (and all related Indemnitees) and for which the
Purchasers (and all related Indemnitees) would otherwise be entitled to
indemnification hereunder shall not exceed $50,000,000.

          (d) Any indemnification payment(s) payable pursuant to this Agreement
shall be decreased by and to the extent of any insurance proceeds or Tax
benefits obtained by an Indemnitee in respect of the Losses giving rise to such
indemnification payment(s).

          (e) To the extent reasonably practicable, the Purchasers shall seek to
combine and jointly pursue any claims or actions that they may have in respect
of a breach by the Company of any of its representations, warranties or
agreements contained herein.


          10.5.  Exclusive Remedy.  Each of the Purchasers acknowledges and
                 ----------------
agrees that (absent securities or other fraud) the sole and exclusive remedy and
recourse (at law or in equity) with respect to any and all Losses relating to or
arising out of the subject matter of this Agreement shall be pursuant, and
