payable with respect to Tax Periods (or portions thereof) ending on or before
the date thereof, and all Taxes attributable to the period commencing on the day
following the date of the Balance Sheet have arisen and been paid in the
Ordinary Course. All Taxes that the Company is or was required by law to
withhold or collect have been duly withheld or collected and, to the extent
required, have been timely paid to the proper Taxing Authority. The Company has

of Taxes on sales or other transactions as to which the Company would have been
obligated to collect or withhold Taxes.

         (c)      There are no liens for Taxes (other than for current Taxes not
yet due and payable) upon any of the assets of the Company. None of the assets
of the Company is required to be treated for Tax purposes as being owned by any
other Person.

         (d)      There are currently no deficiencies for Taxes (other than for
current Taxes not yet due and payable) of the Company. No examination, audit,
subpoena, request for information of any Company Tax Return (or of any
consolidated, combined or unitary group for a period for which the activities of
the Company were included on the Tax Return of such group) by any Taxing
Authority is currently in progress or, to the knowledge of Seller, threatened or
contemplated, nor have Seller or the Company entered into any settlement
agreement with any Taxing Authority with respect thereto. There are no matters
under discussion with any Taxing Authority with respect to Taxes of the Company.
Schedule 4.25(d) of the Disclosure Schedule sets forth the Company Tax Returns
which have been audited within the last six (6) years by the relevant Taxing
Authority for each period set forth in Schedule 4.25(d) of the Disclosure
Schedule. No power of attorney has been executed by or on behalf of the Company

extension or waiver of a statute of limitations relating to Taxes is in effect
with respect to the Company. The Company (nor the members of any consolidated,
combined or unitary group with which the Company has filed group Tax Returns)
has not been notified in writing by any jurisdiction that the jurisdiction
believes that the Company was required to file any Tax Return (or the
consolidated, combined or unitary group with respect to which the Company filed
Tax Returns for any Tax Period was required to file any Tax Return for such Tax
Period) that was not filed. Seller has delivered or otherwise made available to
Buyer complete and accurate copies of all statements of deficiencies for Taxes

law, as a transferee or successor, by contract, or otherwise for any Pre-Closing
Tax Period. For purposes of this Agreement, "Pre-Closing Tax Period" means any

Period ending on the Closing Date. For purposes of this Agreement, "Straddle
Period" means any Tax Period that includes but does not end on the Closing Date.

         (f)      The Company is not obligated to make, and as a result of any
event connected with the transactions contemplated by this Agreement will not
become obligated to make, any "excess parachute payment" within the meaning of
Section 280G of the Code or any similar

                                       20

or local law resulting from the transactions to be executed pursuant to this
Agreement.

         (g)      There are no Tax sharing, indemnity, allocation or similar
agreements in effect as between the Company (or any predecessors thereof) and
any other party. The Company does not have any contractual obligations to
indemnify any other Person with respect to Taxes.

         (h)      The Company will not be required to recognize for Tax purposes
in a Post-Closing Tax Period any income or gain which would otherwise have been
required to be recognized under the accrual method of accounting in a
Pre-Closing Tax Period as a result of Seller or the Company making a change in
method of accounting or otherwise deferring the recognition of income or gain to
a Post-Closing Tax Period as a result of the accounting method used in a
Pre-Closing Tax Period. For purposes of this Agreement, "Post-Closing Tax
Period" means any Tax Period beginning after the Closing Date and that portion
of any Straddle Period beginning after the Closing Date.

         (i)      The Company is not a party to any joint venture, partnership
or other agreement, arrangement or contract that is treated as a partnership for

foreign law.

         (l)      The Company has not made an election, nor is required, to
treat any of its assets as tax-exempt bond financed property or tax-exempt use
property within the meaning of Section 168 of the Code or under any comparable
provision of foreign, state or local Tax law. The Company has not filed a
consent pursuant to the collapsible corporation provisions of Section 341(f) of
the Code (or any corresponding provision of foreign, state or local law) or
agreed to have Section 341(f)(2) of the Code (or any corresponding provision of
state or local law) apply to any disposition of any asset of the Company.

         (m)      None of the Company, Seller or any of their Affiliates has
requested or received any ruling from any Taxing Authority, or signed any
binding agreement with any Taxing Authority that would impact the amount of Tax
liability of the Company after the Closing Date. Since January 1, 2002, none of
the Company, Seller or any of their Affiliates has entered into any closing
agreement or settled or agreed to settle any claim or assessment for Taxes
relating to the Company which involves a payment of $25,000 or more to any
Taxing Authority.

         (n)      To the knowledge of Seller, all terms of any agreements
(whether written or oral) between the Company, on the one hand, and Seller or
its Affiliates, on the other hand, are on an arm's-length basis.

each case as otherwise expressly permitted or contemplated by this Agreement or
with the prior written consent of Seller. Buyer shall disclose the Confidential
Information of Seller, the Company or the Business only to its Representatives
who require such material for the purpose of evaluating the transactions
contemplated hereby and are informed by Buyer of the obligations of this Section
7.3 with respect to such information. Buyer shall (y) enforce the terms of this
Section 7.3 as to its Representatives; (x) take such action to the extent
necessary to cause its Representatives to comply with the terms and conditions
of this Section 7.3; and (z) be responsible and liable for any breach of the
provisions of this Section 7.3 by it or its Representatives. From and after the
Closing, the provisions of Section 13.2 shall control the treatment of the
Confidential Information of Seller, the Company and the Business.

         (b)      Of Transaction. Subject to Section 6.9(c) hereof, except (i)
as expressly permitted or contemplated by this Agreement, (ii) to the
Representatives described in the second sentence of Section 7.3(a) above, (iii)
in the form of a coordinated public announcement promptly after execution of
this Agreement, or (iv) to the extent that, in the opinion of its counsel,
failure to make such disclosure would constitute a violation of Law (and in such
event, after coordination and cooperation with Seller), Buyer shall not disclose
to any Person the fact of, or information regarding, the negotiations with
respect to this Agreement and the transactions contemplated hereby.

         (a)      By written consent of Buyer and Seller;

         (b)      By Buyer or Seller if the Closing shall not have occurred on

         11.2     INDEMNIFICATION

         (a)      By Seller. Seller hereby indemnifies and saves and holds

their respective Representatives (collectively, the "Buyer Indemnified
Persons"), from and against any and all Losses (other than

                                       31

<PAGE>

any Losses specifically taken into account in the purchase price adjustment

                  (i)      subject to Section 11.2(d)(i) and Section 11.2(g),
         any breach of a representation or warranty made by Seller in this
         Agreement or in any document delivered at the Closing (without regard,
         for purposes of this Section 11.2(a)(i), to any qualifications as to

         representations and warranties other than those contained in Section

                  (ii)     any breach of a covenant made by Seller in this
         Agreement;

                  (iii)    subject to Section 11.2(d)(i) and Section 11.2(g),
         any product or component thereof manufactured or shipped by, or service
         provided by, the Company or the Business before the Closing (except for
         any obligation to repair or replace any product or component thereof
         under any warranty or service agreement, written or oral, made in the
         Ordinary Course of the Business before Closing);

                  (iv)     any liability of the Company to, or claim against the
         Company by (x) Seller or Seller's heirs, successors, Representatives or
         assigns, or (y) any Person in connection with the C-Bloc Business or
         Paragon Business, in each case arising out of acts, omissions, events,
         facts or circumstances occurring before the Closing; or

                  (v)      the matters described in Section 11.2(f) ("Tax
         Indemnification") below.

         (b)      By Buyer. Buyer hereby indemnifies and saves and holds
harmless Seller, Seller's Affiliates, and its and their respective
Representatives (collectively, "Seller Indemnified Persons"), from and against
any and all Losses (other than any Losses specifically taken into account in the
purchase price adjustment provided for in Article II) incurred in connection
with or arising out of:

                  (i)      subject to Section 11.2(d)(ii), any breach of a
         representation or warranty made by Buyer in this Agreement or in any
         document delivered at the Closing (without regard, for purposes of this
         Section 11.2(b)(i), to any qualifications as to materiality, Material
         Adverse Change or Material Adverse Effect);

                  (ii)     any breach of a covenant made by Buyer in this
         Agreement;

                  (iii)    subject to Section 11.2(g), the operation of the
         Business by Buyer after the Closing; or

                  (iv)     the matters described in Section 11.2(f) ("Tax
         Indemnification") below.

         (c)      Notice and Defense. Except as provided in Section 11.2(f)(v)
with respect to Tax Claims:

                                       32

<PAGE>

                  (i)      Notice. If a claim for Losses (an "Indemnity Claim")
         is to be made by a party entitled to indemnification hereunder, the
         party claiming such indemnification shall give notice (an "Indemnity
         Claim Notice") to the indemnifying party as promptly as practicable
         after the party entitled to indemnification becomes aware of any fact,
         condition or event which may give rise to Losses for which
         indemnification may be sought. If any Action in the form of a lawsuit
         is filed against any party entitled to indemnification hereunder,
         notice thereof shall be given to the indemnifying party as promptly as
         practicable (and in any event within fifteen (15) calendar days after
         service). The failure of any indemnified party to give timely notice
         hereunder shall not affect rights to indemnification hereunder, except
         to the extent that the indemnifying party demonstrates actual damage
         caused by such failure.

                  (ii)     Conduct of Defense. After such notice, the
         indemnifying party shall be entitled, if it so elects: (x) to take
         control of the defense and investigation of such Action; (y) to employ
         and engage attorneys of its own choice to handle and defend the same
         (unless the named parties to such Action include both the indemnifying
         party and the indemnified party and the indemnified party has been
         advised in writing by counsel that there may be one or more legal
         defenses available to such indemnified party that are potentially in
         conflict with those available to the indemnifying party, in which event
         the indemnified party shall be entitled, at the indemnifying party's
         expense, to one firm of separate counsel of its own choosing); and (z)
         to compromise or settle such Action, which compromise or settlement
         shall be made only with the written consent of the indemnified party,
         which consent shall not be unreasonably withheld, delayed or
         conditioned. If the indemnifying party fails to assume the defense of
         such Action within fifteen (15) calendar days after receipt of the
         Indemnity Claim Notice, the indemnified party against which such Action
         has been asserted will (upon delivering notice to such effect to the
         indemnifying party) have the right to undertake, at the indemnifying
         party's expense, the defense, compromise or settlement of such Action;
         provided, however, that such Action shall not be compromised or settled
         without the written consent of the indemnifying party, which consent
         shall not be unreasonably withheld.

         (d)      Limits on Liability.

                  (i)      Limits on Liability of Seller.

                           (x)      Seller shall not be obligated to indemnify
                  any Buyer Indemnified Person under Section 11.2(a)(i) (Breach
                  of Representation) (other than for a Loss arising from a
                  breach of a representation or warranty contained in Section
                  4.25, which is covered by clause (y) below), under Section
                  11.2(a)(iii), or under Section 11.2(g) (Agreement as to
                  Regulatory Matters) unless and then to the extent such Losses
                  collectively suffered or incurred by all Buyer Indemnified
                  Persons aggregate more than $100,000 (One Hundred Thousand
                  Dollars), in which event Seller shall be obligated to
                  indemnify the applicable Buyer Indemnified Persons for the
                  amount of such Losses in excess of $100,000, up to a

                                       33

<PAGE>

                  maximum amount equal to $3,000,000 (Three Million Dollars),
                  provided, however, that the limitation set forth in this
                  Section 11.2(d)(i)(x) shall not apply to any expenses incurred
                  by any Buyer Indemnified Person in connection with
                  settlements, awards, judgments, attorneys fees and
                  disbursements, and other amounts paid to third parties as a
                  result of third-party product liability claims as to products
                  or components thereof manufactured or shipped by the Company
                  before the Closing; and

                           (y)      Seller shall be obligated to indemnify the
                  Buyer Indemnified Persons for Losses arising from any breaches
                  of a representation or warranty contained in Section 4.25
                  without limitation.

                  (ii)     Limits on Liability of Buyer. Buyer shall not be
         obligated to indemnify any Seller Indemnified Person under Section
         11.2(b)(i) (Breach of Representation) or Section 11.2(g) (Agreement as
         to Regulatory Matters) for Losses pursuant to either such Section
         unless and then to the extent such Losses collectively suffered or
         incurred by all Seller Indemnified Persons aggregate more than $100,000
         (One Hundred Thousand Dollars), in which event Buyer shall be obligated
         to indemnify the applicable Seller Indemnified Persons for the amount
         of such Losses in excess of $100,000, up to a maximum amount equal to
         $3,000,000 (Three Million Dollars).

         (e)      Sole Remedy. The parties acknowledge that, after the Closing,
in the absence of fraud, the rights accorded to each Buyer Indemnified Person or
Seller Indemnified Person under this Article XI shall be the sole rights to
money damages that any such Person may have under this Agreement or for breach
of this Agreement, at common law or otherwise; provided, however, that
notwithstanding the foregoing or anything to the contrary contained in this
Agreement, nothing in this Article XI shall restrict or limit any rights that
any Buyer Indemnified Person or Seller Indemnified Person may have to seek
equitable relief.

         (f)      Tax Indemnification.

                  (i)      From and after the Closing, Seller shall indemnify
         Buyer and its Affiliates (including the Company) in respect of, and
         hold them harmless against, (A) all liability for Taxes of the Company
         (including any obligation to contribute to the payment of a Tax
         determined on a consolidated, combined or unitary basis with respect to
         a group of corporations that includes or included the Company) for all
         Pre-Closing Tax Periods, (B) all liability (as a result of Treas. Reg.
         Section 1.1502-6(a) or otherwise) for Taxes of Seller or any other
         entity which is or has been an Affiliate of the Company, (C) any and
         all Losses arising out of, resulting from or incident to any breach by
         Seller or any of its Affiliates of any covenant contained in Article
         XIV, and (D) any and all Losses arising out of, resulting from or
         incident to the breach of any representation, warranty or covenant
         contained in Section 4.25, except to the extent that any such Losses
         are otherwise indemnified pursuant to Section 11.2(a)(i)-(iv). For
         purposes of this Section 11.2(f), Taxes shall include the amount of
         Taxes which would have been paid but for the

                                       34

<PAGE>

         application of any credit or net operating loss or capital loss
         deduction attributable to Post-Closing Tax Periods.

                  (ii)     From and after the Closing, Buyer shall indemnify
         Seller and its Affiliates in respect of, and hold them harmless
         against, (i) all liability for Taxes of the Company (including any
         obligation to contribute to the payment of a Tax determined on a
         consolidated, combined or unitary basis with respect to a group of
         corporations that includes or included the Company) for any
         Post-Closing Tax Period, except to the extent such Taxes are
         attributable to a breach by Seller or any of its Affiliates of any
         covenant contained in Article XIV or a representation, warranty or
         covenant contained in Section 4.25, and (ii) any and all Losses arising
         out of, resulting from or incident to the breach by Buyer or any of its
         Affiliates of any covenant contained in Article XIV.

                           (iii)    In the case of any Straddle Period:

                                    (A)      real, personal and intangible
                                    property Taxes and any other Taxes levied on
                                    a per diem basis ("Per Diem Taxes") of the
                                    Company for a Pre-Closing Tax Period shall
                                    be equal to the amount of such Per Diem
                                    Taxes for the entire Straddle Period
                                    multiplied by a fraction, the numerator of
                                    which is the number of days during the
                                    Straddle Period that are in the Pre-Closing
                                    Tax Period and the denominator of which is
                                    the total number of days in the Straddle
                                    Period; and

                                    (B)      the Taxes of the Company (other
                                    than Per Diem Taxes) for any Pre-Closing Tax
                                    Period shall be computed as if such taxable
                                    period ended as of the close of business on
                                    the Closing Date.

                  (iv)     Seller's indemnity obligation in respect of Taxes for
         a Pre-Closing Tax Period shall initially be effected by its payment to
         Buyer of the excess of (A) any such Taxes for a Pre-Closing Tax Period
         (as may be evidenced by any Tax Return prepared by Buyer in accordance
         with Section 14.1(b)) or as otherwise indicated in a written notice
         prepared by Buyer) over (B) the amount of such Taxes paid by Seller or
         any of its Affiliates, other than the Company, at any time plus the
         amount of such Taxes paid by the Company on or prior to the Closing
         Date. Seller shall pay such excess to Buyer within ten (10) days after
         written demand is made by Buyer (but in no event does such payment have
         to be made earlier than five (5) days before the date on which Taxes
         for the relevant Tax Period are required to be paid to the relevant
         Taxing Authority). If the amount of any such Taxes paid by Seller or
         any of its Affiliates (other than the Company) at any time plus the
         amount of such Taxes paid by the Company on or prior to the Closing
         Date exceeds the amount of such Taxes for the Pre-Closing Tax Period,
         Buyer shall pay to Seller the amount of such excess within ten (10)
         days after the Tax Return with respect to the final liability for such
         Taxes is required to be filed with the relevant Taxing Authority. In
         the case of a Tax that is contested in accordance with the provisions
         of clause (v) below, payment of the Tax to the appropriate Taxing
         Authority shall not be considered to

                                       35

<PAGE>

         be due earlier than the date a final determination to such effect is
         made by the appropriate Taxing Authority or court.

                  (v)      The parties further agree as follows:

                           (A)      If a claim shall be made by any Taxing
                           Authority, which, if successful, might result in an
                           indemnity payment to an indemnified party or one of
                           its Affiliates pursuant to this Section 11.2(f), the
                           indemnified party shall promptly and in any event no
                           more than thirty (30) days following the indemnified
                           party's receipt of such claim, give written notice to
                           the indemnifying party of such claim (a "Tax Claim");
                           provided, however, the failure of the Indemnified
                           Party to give such notice shall only relieve the
                           Indemnifying Party from its indemnification
                           obligations hereunder to the extent it is actually
                           prejudiced by such failure.

                           (B)      With respect to any Tax Claim relating to a
                           taxable period ending on or prior to the Closing
                           Date, Seller shall, upon written notification to
                           Buyer of its desire to, control all proceedings and
                           may make all decisions taken in connection with any
                           such Tax Claim (including selection of counsel) at
                           its own expense; provided, however, that Seller and
                           Buyer shall be entitled to jointly control any such
                           Tax Claims the resolution of which could result in an
                           increase in Taxes of the Company for tax periods
                           ending after the Closing Date. Seller and Buyer shall
                           be entitled to jointly control all proceedings taken
                           in connection with any Tax Claim relating solely to
                           Taxes of the Company for a Straddle Period. Buyer
                           shall control at its own expense all proceedings with
                           respect to any Tax Claim relating to a taxable period
                           beginning after the Closing Date. A party shall
                           promptly notify the other party if it decides not to
                           control the defense or settlement of any Tax Claim
                           which it is entitled to control pursuant to this
                           Agreement, and the other party shall thereupon be
                           permitted to defend and settle such proceeding.

                           (C)      Seller, Buyer, and the Company and each of
                           their respective Affiliates shall reasonably
                           cooperate with each other in contesting any Tax
                           Claim. Such cooperation shall include the retention
                           and, upon the request of the party or parties
                           controlling proceedings relating to such Tax Claim,
                           the provision to such party or parties of records and
                           information which are reasonably relevant to such Tax
                           Claim, and making employees available on a mutually
                           convenient basis to provide additional information or
                           explanation of any material provided hereunder or to
                           testify at proceedings relating to such Tax Claim.

         (g)      Agreement as to Regulatory Matters. Notwithstanding anything
to the contrary herein (including Section 4.17 hereof), the parties hereto

Closing.

         13.2     POST-CLOSING CONFIDENTIALITY

         (a)      Seller. Subject to Section 6.9(c) hereof, after the Closing,
Seller shall, and shall cause its Affiliates and Representatives to, continue to
maintain the confidentiality of all Confidential Information relating to Buyer,
the Company (other than the C-Bloc Business or Paragon Business conducted by the
Company) or the Business, including all such materials which remain in the
possession of Seller or such Affiliates or Representatives, except to the extent
that disclosure of any such information is required by law or authorized in
writing by Buyer, or reasonably occurs in connection with any dispute over the
terms of this Agreement.

         (b)      Buyer. Subject to Section 6.9(c) hereof, Buyer shall, and
shall cause its Affiliates and Representatives to, maintain the confidentiality
of all Confidential Information relating to Seller or Seller's Affiliates
(excluding that relating to the Company or the Business, but

                                       38

<PAGE>

including that relating to the C-Block Business), which Buyer or any of its
Affiliates or Representatives has obtained in connection with this Agreement,
with the transactions contemplated herein, or operation of the Company, except
to the extent disclosure of such information is required by law or authorized in
writing by Seller, or reasonably occurs in connection with any dispute over the
terms of this Agreement. To facilitate compliance with the foregoing, Buyer
agrees that, until the second anniversary of the Closing Date, Buyer shall not,
and Buyer shall cause its Affiliates (including the Company) to not, directly or
indirectly, employ, engage as a consultant, or otherwise utilize or cooperate
with Robert B. Keahey in any business or activity that competes with Seller's
C-Bloc Business or Paragon Business; provided however, that the conduct of the
Business by Buyer in the manner the Business is conducted by Seller as of the
date hereof shall not be deemed to be a business or activity that competes with
Seller's C-Bloc Business or Paragon Business.

         (c)      Requirements of Law. In the event that either party reasonably
believes that it or any of its Affiliates is required by Law to disclose any

confidential treatment will be accorded such Confidential Information and (ii)
cooperate with such other party in attempting to obtain such order or assurance.

         13.3     2003 MANAGEMENT INCENTIVE PLAN.

                                   ARTICLE XIV
                                   TAX MATTERS

         14.1     PREPARATION AND FILING OF TAX RETURNS; PAYMENT OF TAXES.

         (a)      Subject to Section 14.3(f), for any taxable period of the
Company that ends on or before the Closing Date, Seller shall timely prepare,
consistent with past practices and custom of the Company (unless a contrary
position is required by law), and file with the appropriate Tax Authority all
required consolidated, combined or unitary Tax Returns that include any of the
Company (and shall promptly provide Buyer with copies of all such Tax Returns
insofar as such Tax Returns relate to the Company) and shall make or cause to be
made all payments required with respect to any such Tax Returns. Seller shall
not file any Tax Return relating to a Pre-Closing Tax Period without Buyer's
consent (which shall not be unreasonably withheld) if the filing of such Tax
Return may cause a net increase of the Tax liability of the Company for a
Post-Closing Tax Period.

         (b)      Buyer shall timely prepare and file with the appropriate
Taxing Authority all other Company Tax Returns relating to a Pre-Closing Tax
Period or Straddle Period required to be

                                       39

<PAGE>

filed after the Closing Date and shall pay all Taxes due with respect to such
Tax Returns. Any Tax Return prepared and filed by Buyer for a Pre-Closing Tax
Period or Straddle Period shall be prepared consistent with past practices and
custom of the Company (unless a contrary position is required by law) to the
extent such Tax Returns relate to the Taxes of the Company for a Pre-Closing Tax
Period, and Seller shall pay Buyer (in accordance with the procedures set forth
in Section 11.2(f)) for any amount owed by Seller pursuant to Section 11.2(f)
with respect to any such Tax Returns.

         (c)      Seller shall be responsible for filing any amended
consolidated, combined or unitary Tax Returns that include the Company for
taxable years ending on or prior to the Closing Date that are required as a
result of examination adjustments made by the Internal Revenue Service or by the
applicable state, local or foreign Taxing Authorities for such taxable years as
finally determined. For those jurisdictions in which separate Tax Returns are
filed by the Company, any required amended Tax Returns for taxable years ending
on or prior to the Closing Date resulting from such examination adjustments, as
finally determined, shall be prepared by Buyer and a copy thereof shall be
furnished to Seller. Seller shall not file any amended, consolidated, combined
or unitary Tax Returns that include the Company for a period ending on or before
the Closing Date without Buyer's consent (which consent shall not be
unreasonably withheld) if the filing of any such amended Tax Return may affect
the Tax liability of the Company for which Buyer is liable.

         (d)      Seller shall be responsible for the payment of all transfer,
sales, use, stamp, conveyance, value added, recording, registration,
documentary, filing and other non-income Taxes and administrative fees
(including, without limitation, notary fees) arising in connection with the
consummation of the transactions contemplated by this Agreement. Seller and
Buyer shall cooperate in preparing and filing all Tax Returns and other
documentation on a timely basis as may be required with respect to the payment
of such Taxes and fees.

         14.2     ALLOCATION OF CERTAIN TAXES.

         (a)      Buyer and Seller agree that if the Company or Seller is
permitted but not required under applicable foreign, state or local Tax laws to
treat the Closing Date as the last day of a taxable period with respect to the
Company, Buyer and Seller shall treat such day as the last day of a taxable
period.

         (b)      Any Taxes for a Straddle Period shall be apportioned in a
manner consistent with Section 11.2(f)(iii) hereof.

         14.3     REFUNDS AND CARRYBACKS.

         (a)      Seller shall be entitled to any refunds (including any
interest paid thereon) or credits of Taxes attributable to any Pre-Closing Tax
Period to the extent provided by law, except to the extent that such refund or
credit arises as a result of a carryback of a Company loss or other tax benefit
arising from a period beginning after the Closing Date as provided in Section
14.3(f).

                                       40

<PAGE>

         (b)      Buyer and/or its Affiliates, as the case may be, shall be
entitled to any refunds (including any interest paid thereon) or credits of
Taxes attributable to any Post-Closing Tax Period.

         (c)      The amount or economic benefit of any refunds or credits of
Taxes attributable to any Straddle Period shall be equitably apportioned in a
manner consistent with Section 11.2(f)(iii) hereof.

         (d)      Buyer (and its Affiliates) shall forward to or reimburse
Seller for any refunds (including any interest paid thereon) or credits due
Seller after receipt thereof, and Seller (and its Affiliates) shall promptly
forward to Buyer or reimburse Buyer for any refunds (including any interest paid
thereon) or credits due Buyer after receipt thereof.

         (e)      Provided that the non-requesting Party, acting in good faith,
determines that there is a reasonable basis for filing a claim with the relevant
Taxing Authority, and subject to the provisions of Section 14.1, each party
shall, if the other party so requests and at such other party's expense, cause
the Company to file for and obtain any refunds, credits or offsets to Taxes to
which the requesting party is entitled under this Section 14.3. Buyer shall
permit Seller to control the prosecution of any such claim relating solely to
one or more Taxable Periods ending on or before the Closing Date.
Notwithstanding the foregoing, the control of the prosecution of a claim for a
refund of Taxes paid pursuant to a deficiency assessed subsequent to the Closing
Date as a result of an audit shall be governed by the provisions of Section
11.2(f)(v).

         (f)      If the Company generates a credit or loss that is carried back
to offset income for a period ending on or prior to the Closing Date and if
Seller or its Affiliates realize a reduction in Tax for such period as a result
of such carryback (either in the form of a refund or an offset), Seller shall
pay to Buyer the amount of such reduction within ten (10) days after the receipt
of the refund or the offset. Seller shall, at the request of Buyer, cooperate in
connection with the filing of any necessary Tax Returns and other documents to
effect such a carryback at Buyer's expense, and Seller shall provide a basis for
the computation of the amount paid to Buyer pursuant to this Section 14.3(f) in
reasonable detail.

         14.4     COOPERATION ON TAX MATTERS.

         Buyer and Seller and their respective Affiliates shall cooperate in the
preparation of all Company Tax Returns for any Tax Periods for which one party
could reasonably require the assistance of the other party in obtaining any
necessary information and documents. Such cooperation shall include, furnishing
prior years' Tax Returns or return preparation packages to the extent related to
the Company illustrating previous reporting practices or containing historical
information relevant to the preparation of such Tax Returns, and furnishing such
other information within such party's possession requested by the party filing
such Tax Returns as is relevant to their preparation. Such cooperation and
information also shall include, without limitation, provision of powers of
attorney for the purpose of signing Tax Returns and defending audits and
promptly forwarding copies of appropriate notices and forms or other
communications received from or sent to any applicable Governmental Entity
responsible for the imposition or

                                       41

administration of Taxes ("Taxing Authority") which relate to the Company, and
providing copies of all relevant Tax Returns to the extent related to the
Company, together with accompanying schedules and related workpapers, documents
relating to rulings or other determinations by any Taxing Authority and records
concerning the ownership and Tax basis of property, which the requested party
may possess. Seller and Buyer agree (i) to retain all books and records with
respect to Tax matters pertinent to the Company relating to any Tax Period
beginning before the Closing Date until the applicable statute of limitations
with respect to Taxes for the Company has expired and to abide by all record
retention agreements entered into with any Taxing Authority; (ii) to allow the
other party and its representatives at times and dates mutually acceptable to
the parties, to inspect, review and make copies of such records as such party
may deem necessary or appropriate from time to time, such activities to be
conducted during normal business hours at such party's expense; and (iii) to
give the other party reasonable written notice prior to transferring, destroying
or discarding any such books and records and, if the other party so requests,
Seller and Buyer, as the case may be, shall allow the other party to take
possession of such books and records. Buyer and Seller and their respective
Affiliates shall make their respective employees and facilities reasonably
available on a mutually convenient basis to explain any documents or information
provided hereunder.

         14.5     TERMINATION OF TAX SHARING AGREEMENTS.

         All Tax sharing agreements or similar arrangements with respect to or
involving the Company shall be terminated prior to the Closing Date and, after
the Closing Date, Buyer and its Affiliates shall not be bound thereby or have
any liability thereunder.

         15.1     ASSIGNMENT; NO THIRD PARTY BENEFICIARIES

         Neither this Agreement nor any of the rights or obligations hereunder
may be assigned by any party without the prior written consent of the other
parties, except that Buyer may assign its rights and obligations hereunder to
one or more of its Affiliates as long as Buyer also remains liable for its
obligations hereunder. This Agreement shall be binding upon and inure to the

assigns, and no other Person (including any Business Employee) shall have any
right, benefit or obligation under this Agreement as a third party beneficiary

         15.3     CHOICE OF LAW, ETC.

         This Agreement shall be construed and interpreted in accordance with
the internal laws of the State of Delaware, except with respect to matters of
law concerning the internal affairs of any business entity which is a party to
this Agreement, and as to those matters the law of the jurisdiction under which
the relevant business entity derives its powers shall govern. Each party
irrevocably and unconditionally: (i) agrees that any Action arising out of this
Agreement or any Additional Agreement shall be brought in Delaware court, (ii)
consents to such jurisdiction, (iii) waives any objection to such venue; and
(iv) waives trial by jury in any Action relating to this Agreement, any
Additional Agreements or the transactions contemplated hereby or thereby.

         15.4     ENTIRE AGREEMENT; AMENDMENTS AND WAIVERS

         This Agreement and the Additional Agreements, together with all
exhibits and schedules hereto and thereto (including the Disclosure Schedule),
constitute the entire agreement among the parties pertaining to the subject
matter hereof and supersede all prior agreements, understandings, negotiations
and discussions, whether oral or written, of the parties with respect thereto.
No amendment, supplement, modification or waiver of this Agreement shall be
binding unless executed in writing by the party to be bound thereby. No waiver
of any of the provisions of this Agreement shall be deemed or shall constitute a
waiver of any other provision hereof, nor shall such waiver constitute a
continuing waiver unless otherwise expressly provided in such waiver.

         15.5     COUNTERPARTS

         This Agreement may be executed in one or more counterparts, each of
which shall be deemed an original, but all of which together shall constitute
one and the same instrument.

         15.6     EXPENSES

         Except as otherwise specifically provided in this Agreement (for
example, in Section 14.1(d)), each party hereto shall pay its own legal,
accounting, out-of-pocket and other expenses incident to the negotiation and
execution of, and Closing under, this Agreement, and Seller shall pay any such
expenses of the Company; provided, however, that Buyer and Seller shall each pay
one-half of the fees and expenses of any accounting firm that is retained to
resolve a dispute under Section 2.3.

         15.7     INVALIDITY

         In the event that any of the provisions contained in this Agreement
shall, for any reason, be held to be invalid, illegal or unenforceable in any
respect, then, to the maximum extent permitted by law, such invalidity,
illegality or unenforceability shall not affect any other provision of this
Agreement.

         15.8     CUMULATIVE REMEDIES

         Except as otherwise specifically provided in this Agreement (in Section
11.2(e) or otherwise) or any Additional Agreement, all rights and remedies of
any party hereto are cumulative of each other and of every other right or remedy
such party may otherwise have at law or in equity, and the exercise of one or
more rights or remedies shall not prejudice or impair the concurrent or
subsequent exercise of other rights or remedies.

         15.9     TIME; CAPTIONS; EXHIBITS AND SCHEDULES

         Time is of the essence of this Agreement. The captions contained in
this Agreement in no way define, limit or extend any provision of this
Agreement. The Exhibits and Schedules which are attached to this Agreement are a
part of this Agreement and are incorporated herein by reference.

         15.10    FURTHER ASSURANCES

         The parties shall cooperate reasonably with each other and with their
respective Representatives in connection with any steps required to be taken as
part of their respective obligations under this Agreement, and shall (a) furnish
upon request to each other such further information; (b) execute and deliver to
each other such other documents; and (c) do such other acts and things, all as
the other party may reasonably request for the purpose of carrying out the
intent of this Agreement and the transactions contemplated herein.

         15.11    NO STRICT CONSTRUCTION

         The language used in this Agreement shall be deemed to be the language
chosen by the parties hereto to express their mutual intent, and no rule of
strict construction shall be applied against any Person.
