                            STOCK PURCHASE AGREEMENT

                  THIS STOCK PURCHASE AGREEMENT (this "Agreement") is entered
into as of July 12, 2007, by and among MACE SECURITY INTERNATIONAL, INC., a
Delaware corporation ("Purchaser"), LINKSTAR INTERACTIVE, INC., a Delaware
corporation (the "Company") and MAURRY MENDELOVICH, COLIN McINTYRE, MICHAEL

"Shareholders"). Capitalized terms used herein and not otherwise defined have
the meanings set forth in Section 9.13 hereof.



                              W I T N E S S E T H:

                  WHEREAS, after giving effect to the Redemption (as defined
below) which shall occur prior to the Closing, Shareholders collectively will
own one hundred percent (100%) of the outstanding capital stock issued by the
Company;

                  WHEREAS, Purchaser desires to acquire one hundred percent
(100%) of the outstanding capital stock issued by the Company; and

                  WHEREAS, Shareholders desire to sell and Purchaser desires to
purchase one hundred percent (100%) of the outstanding capital stock issued by
the Company at the price and upon the terms and conditions hereinafter set
forth.

                  NOW, THEREFORE, in consideration of the premises and the
mutual covenants, representations and warranties contained herein and intending
to be legally bound hereby, the parties hereto hereby agree as follows:



                                    ARTICLE I
                     SALE AND PURCHASE OF OUTSTANDING STOCK

         Section 1.1       Sale and Purchase of Outstanding Stock.

                  On the terms and subject to the conditions contained herein,
on the Closing Date, each Shareholder agrees to sell to Purchaser, and Purchaser
agrees to purchase from each Shareholder the common stock of the Company listed
on Annex A attached (the "Company Stock"), which common stock in the aggregate
will constitute at the Closing one hundred percent (100%) of all of the
Company's issued and outstanding capital stock, for the aggregate purchase price
specified in Section 1.2 and Section 1.3 (the "Purchase").

         Section 1.2       Purchase Price.

                  The aggregate purchase price for the Company Stock being sold
hereunder shall be an amount equal to Ten Million Three Hundred Fifty Thousand
Dollars ($10,338,000) (the "Purchase Price"), payable as set forth in Section
1.3 below and subject to adjustment pursuant to Section 1.4(e) below.



                                                                  Execution Copy

         Section 1.3       Payment Terms.

                  On the terms and subject to the conditions set forth herein,
in consideration of the Company Stock being sold hereunder, on the Closing Date,
Purchaser shall pay each Shareholder such Shareholder's pro rata share of the
Purchase Price in the percentage set forth on Annex A (the "Pro Rata
Percentage"). The payment to each Shareholder at the Closing will be the Pro
Rata Percentage of the following:

                  (a) To each Shareholder, the Shareholder's Pro Rata Percentage
of Six Million Eight Hundred Fifty Thousand Dollars ($6,838,000), in cash (the
"Cash Consideration"), by wire transfer of immediately available United States
funds to such account as such Shareholder may designate to Purchaser at least
five (5) Business Days before the Closing Date;

                  (b) To each Shareholder, a promissory note in the original
principal amount equal to the Shareholder's Pro Rata Percentage of five hundred
thousand dollars ($500,000), which promissory note will be issued by Purchaser
bearing 5% interest per annum and due and payable, principal plus interest, on
January 3, 2008, in the form attached hereto as Annex B (the "Promissory
Notes");

                  (c) To each Shareholder, shares of the Purchaser's common
stock (the "MSI Common Stock") equal to the Shareholder's Pro Rata Percentage of
$3,000,000 in amount, with each share of the MSI Common Stock being valued at
the closing sales price of shares of Purchaser's common stock as reported by the
Nasdaq Global Market on the trading day which is the fifth trading day prior to
the Closing Date. Each Shareholder shall have registration rights for the MSI
Common Stock each receives as set forth in a separate Registration Rights
Agreement in form and substance to be agreed to by the parties as a condition to
Closing (the "Registration Rights Agreement") to be entered into by each
Shareholder and the Purchaser on the Closing Date. The MSI Common Stock shall
not be registered under the Securities Act of 1933 or any state securities laws.
The stock certificates to be delivered evidencing the MSI Common Stock will have
a restrictive legend stating the shares have not been registered under the
Securities Act of 1933. The Registration Rights Agreement each Shareholder is to
execute at Closing will have a provision providing that the Shareholder will not
sell the MSI Common Stock received at Closing for a period of one year from the
Closing Date and will agree to sell no more than one-half of the MSI Common
Stock such Shareholder received at the Closing during the period starting one
year from the Closing Date and ending two years from the Closing Date.

         Section 1.4       Cash; Indebtedness; and Working Capital.

                  (a) On or prior to the Closing Date, prior to the calculation
of Working Capital under the provisions of Section 1.4(c) below, Shareholders
may cause the Company to distribute to the Shareholders and/or its employees any
and all cash of the Company and its Subsidiaries; provided that any distribution
shall be calculated in good faith to result in the Company having the Minimum
Working Capital after the distribution and payments described under Section
1.4(b) are made. Purchaser shall be given written notice of any distribution
prior to or promptly after it being made.

                                                                             -2-


                                                                  Execution Copy

                  (b) On or prior to the Closing Date, prior to the calculation
of Working Capital to be made under Section 1.4(c) below, Shareholders shall, or
shall cause the Company to: (i) repay any outstanding indebtedness for borrowed
money (including accrued and unpaid interest thereon) of the Company and its
Subsidiaries, except for the outstanding indebtedness for borrowed money set
forth in Section 1.4(b) of the Company Disclosure Schedules; and (ii) pay or
book any and all expenses relating to entering into and consummating this
Agreement, including without limitation, all travel expenses, legal expenses and
accounting fees.

                  (c) The Cash Consideration has been agreed upon based on the
Company having as of the Closing Date the Minimum Working Capital. On the
Closing Date, the Working Capital as of the Closing Date will be estimated by
the Purchaser and the Company using a balance sheet prepared by the Company and
reviewed by the Purchaser ("Estimated Working Capital"). The Shareholders shall
cause the Company to use commercially reasonable efforts to have an Estimated
Working Capital of no less than the Minimum Working Capital. In the event that
the Estimated Working Capital is less than the Minimum Working Capital by more
than $100,000, the Cash Consideration payable at the Closing will be reduced on
a dollar-for-dollar basis to the extent less than the Minimum Working Capital.
As soon as practicable after the Closing Date, but in no event later than the
60th day after the Closing Date, a Shareholder Majority shall prepare or cause
to be prepared and shall deliver to Purchaser a worksheet (the "Final Working
Capital Worksheet") calculating the actual Working Capital of the Company as of
the Closing Date (the "Final Working Capital"), as determined on a consolidated
basis in accordance with GAAP by the Company consistent with the basis on which
it prepared its May 31, 2007 balance sheet, provided that any items of income
and expense that are reported on an aggregated monthly basis shall be pro rated
for the month of July through the Closing Date. The Shareholder Majority shall
provide to Purchaser all supporting work papers and other supporting information
used to prepare the Final Working Capital Worksheet as may be reasonably
requested by Purchaser.

                  (d) The Final Working Capital Worksheet and the Final Working
Capital shall be deemed conclusive and binding on the parties for purposes of
this Section 1.4 unless Purchaser notifies the Shareholders in writing within
thirty (30) days after receipt of the Final Working Capital Worksheet of
Purchaser's disagreement therewith, which notice shall state with reasonable
specificity the reasons for any disagreement and identify the items and amounts
in dispute (the "Objections"). Thereafter, Purchaser and a Shareholder Majority
shall endeavor in good faith, for a period not to exceed 30 days from the date
of delivery of such notice, to resolve the Objections. If at the end of the
30-day period there are any unresolved Objections, at the request of either
party, Purchaser and a Shareholder Majority shall promptly engage, on standard
terms and conditions for a matter of such nature, the Pittsburgh, Pennsylvania
office of Alpern Rosenthal (or another mutually acceptable recognized
independent accounting firm of regional standing who does not have a
pre-existing relationship with Purchaser, Shareholders or the Company) to
determine the Final Working Capital. The engagement agreement with the
independent accountants shall require the independent accountants to make their
determination with respect to the Objections and amount of the Final Working
Capital within forty-five (45) days following their engagement. Purchaser and
the Shareholders shall each pay one-half of the fees and expenses of such
independent accountants. The resolution by the independent accountants of any
dispute shall be final, binding and conclusive upon the parties and shall be the
parties' sole and exclusive remedy regarding any dispute concerning the
calculation of the Final Working Capital; provided, however, the limitations set
forth in this Section shall not impair or affect the rights of any of the
parties to seek equitable relief, including specific performance or injunctive
relief with respect hereto, or affect the rights of any of the parties to
redress any Losses arising out of fraud by any other party in connection
herewith.

                                                                             -3-

                                                                  Execution Copy

                  (e) The Purchase Price shall be adjusted on a
dollar-for-dollar basis upwards or downwards to the extent that the Final
Working Capital is greater or less than the Minimum Working Capital, as the case
may be. If the Final Working Capital as established pursuant to the preceding
Section varies from the Minimum Working Capital, the following shall occur, as
applicable, (i) Purchaser shall pay each Shareholder, in cash, an amount, if
any, equal to the Pro Rata Percentage by which the Final Working Capital exceeds
the Minimum Working Capital; or (ii) each Shareholder shall pay Purchaser the
amount, if any, equal to the Pro Rata Percentage by which the Final Working
Capital was less then the Minimum Working Capital. The payment, if any is owed
by the Shareholders, shall be paid to Purchaser by Purchaser receiving a credit
from each Shareholder against the Promissory Note held by such Shareholder in
the Pro Rata Percentage of the aggregate amount owed with the balance, if any,
being paid in cash. Neither party shall be liable for indemnification under
Article VIII with respect to the Working Capital to the extent that such party
has benefited from an adjustment to the Purchase Price under this Section 1.4.

         Section 1.5       Excluded Assets

                  The parties to this Agreement acknowledge that the
Shareholders have some personal possession at the Company's offices. The assets
listed in Section 1.5 of the Company Disclosure Schedules (the "Excluded
Assets"), are personal assets of the Shareholders as identified in Section 1.5
and are not owned by the Company.

         Section 1.6       Stock Options, Warrants and Capital Contribution.

                  (c) by Purchaser, if there has been a material breach of any
of the representations, warranties, agreements or covenants set forth in this
Agreement on the part of Shareholders or the Company which, if not cured, would
reasonably be expected to render the satisfaction of any of the conditions set
forth in Section 7.2 impossible and such breach has not been cured within ten

                  (d) by a Shareholder Majority, if there has been a material

                  (a) In the event that this Agreement is validly terminated in
accordance with Section 2.3 and Section 2.4, then, subject to the provisions of
this Section 2.5, each of the Shareholders, Company and Purchaser shall be
relieved of their respective duties and obligations arising under this Agreement
after the date of such termination, and such termination shall be without
liability to Purchaser, Shareholders or the Company; provided, however, that no

non-breaching party shall include all attorneys' fees reasonably incurred by
such party in connection with the transactions contemplated hereby.

                                                                             -7-

to be delivered by Shareholders and the Company to Purchaser on or before July

         Section 3.1       Corporate Organization; Subsidiaries.

                  (a) The Company is a corporation duly organized, validly
existing and in good standing under the Laws of the State of Delaware. The
Company has corporate power and authority to own or lease all of its properties
and assets and to carry on its business as it is now being conducted and as it
is currently contemplated to be conducted. The Company is qualified to do
business in each jurisdiction in which the nature of its business or the
ownership of its properties makes such qualification necessary, except for where
such failures to be so qualified would not have a Material Adverse Effect. The
copies of the certificate of incorporation and bylaws of the Company
(collectively, the "Organizational Documents"), which are attached hereto at
Section 3.1(a) of the Company Disclosure Schedules, are true, correct and
complete copies of such documents as in effect on the date of this Agreement.

forth the name of each of the Subsidiaries of the Company, and, with respect to
each Subsidiary, the jurisdiction in which it is incorporated or organized and
the Company's ownership interest therein. Each Subsidiary is a duly organized
and validly existing corporation validly existing or in good standing under the
Laws of the jurisdiction of its organization and is duly qualified to do
business in each jurisdiction in which the nature of its business or the
ownership of its properties requires such qualification, except for where such
failures to be so qualified would not have a Material Adverse Effect. The copies
of the articles of incorporation and bylaws of each of the Subsidiaries of the
Company (collectively, the "Subsidiary Organizational Documents") which are
attached hereto at Section 3.1(b) of the Company Disclosure Schedules, are true,
correct and complete copies of such documents as in effect on the date of this
Agreement.

                                                                             -8-


                                                                  Execution Copy

         Section 3.2       Capitalization.

                  Shareholders are the only owners of the outstanding capital
stock of the Company and, as the only owners of the outstanding capital stock
issued by the Company, hold of record and beneficially all of the outstanding
common stock issued by the Company free and clear of any Liens. After giving
effect to the Option Cancellation, there are not outstanding any preferred stock
or other securities of the Company or its Subsidiaries or any options, warrants,
rights or agreements, orally or in writing, relating to the issuance, sale or
transfer of any equity securities or other securities of the Company or its
Subsidiaries.

         Section 3.3       No Violation.

                  All corporate action on the part of the Company and
Shareholders necessary for the authorization, execution, delivery and
performance of this Agreement and the transactions contemplated hereby have been
taken by the Company and the Shareholders or will be taken by them prior to the
Closing. Except as set forth on Section 3.3 of the Company Disclosure Schedules,
the execution, delivery and performance by Shareholders of this Agreement does
not, and the consummation of the transactions contemplated hereby will not,
conflict with, or result in any violation of or default (with or without notice
or lapse of time, or both) under, or give rise to a right of termination or
cancellation under, any provision of (a) the Organizational Documents of the
Company or any organizational documents of any of its Subsidiaries; (b) any
applicable Law or applicable order, judgment or decree issued by any
Governmental Entity which names the Company or any of its Subsidiaries or any of
their respective assets (each, an "Order") of any court, administrative agency
or commission or other governmental or regulatory authority or instrumentality
(each, a "Governmental Entity"), (c) any contract, lease, loan agreement,
mortgage, security agreement or other agreement or instrument to which the
Company or any of its Subsidiaries is a party or by which the Company or any of
its Subsidiaries is bound or to which any of the Company's or its Subsidiaries'
properties or assets is subject, or (d) any of the approvals, authorizations,
consents, licenses, permits or certificates (the "Permits") granted by a
Governmental Entity to the Company or its Subsidiaries.

         Section 3.4       Consents and Approvals.

                  Except as disclosed on Section 3.4 of the Company Disclosure
Schedules, no consent, waiver, authorization, approval, Order or Permit of or
from, or registration, declaration or filing with, or notice to any Governmental
Entity or any other Person, is required by the Company or any of its
Subsidiaries in connection with the execution and delivery of this Agreement or
the consummation of the transactions contemplated hereby.

adjustments and the absence of notes, and are consistent with the books and
records of the Company and its Subsidiaries (which books and records are correct
and complete in all material respects).

                                                                             -9-

                                                                            -30-


         Section 8.2       Indemnification by Shareholders.

                  (a) Subject to Section 8.5 and the other provisions of this
Article VIII, Shareholders, jointly and severally, hereby agree to reimburse,
defend, indemnify and hold Purchaser and Company and its directors, officers,
employees, Affiliates, stockholders, agents, attorneys, representatives,
successors and permitted assigns (collectively, the "Purchaser Indemnified
Parties") harmless from and against any and all losses, liabilities,
obligations, damages and expenses (including without limitation reasonable
attorneys' fees and court costs) (individually, a "Loss" and, collectively,
"Losses") based upon or resulting from:

                           (i) any breach of or falsity of any of the
         representations or warranties made by Shareholders or the Company under
         Article III in this Agreement; or

                           (ii) any breach of or failure to perform any covenant

Article VIII, each Shareholder, severally and not jointly, hereby agrees to
reimburse, defend, indemnify and hold the Purchaser Indemnified Parties harmless

                           (i) any breach of or falsity of any of the
         representations or warranties made by such Shareholder under Article IV
         in this Agreement; or

                           (ii) any breach of or failure to perform any covenant
         or agreement made by such Shareholder under Section 6.11.

                  (c) Purchaser acknowledges and agrees that Shareholders shall
not have any liability under any provision of this Agreement for any Loss to the
extent that such Loss relates to action taken by Purchaser or its Affiliates
after the Closing Date. Purchaser shall take and shall cause its Affiliates to

which would reasonably be expected to, or does, give rise thereto.

                                                                            -31-



                                                                  Execution Copy

         Section 8.3       Indemnification by Purchaser and the Company.

                  (a) Subject to Section 8.5 and the other provisions of this
Article VIII, Purchaser and the Company, jointly and severally, hereby agree to
reimburse, defend, indemnify and hold Shareholders and their Affiliates, agents,
attorneys, representatives, and successors (collectively, the "Shareholder
Indemnified Parties") harmless from and against any and all Losses based upon or
resulting from:

                           (i) any breach of or falsity of any of the
         representations or warranties made by Purchaser in this Agreement; or

                           (ii) any breach of or failure to perform any covenant
         or agreement made by Purchaser in this Agreement.

the extent that such Loss relates to actions taken by Shareholders or Company
prior to the Closing Date. Shareholders shall take and cause its Affiliates to
take all reasonable steps to mitigate any Loss upon becoming aware of any event
which would reasonably be expected to, or does, give rise thereto.

         Section 8.4       Indemnification Procedures.

                  (a) In the event that indemnification may be sought under this
Article VIII (an "Indemnification Claim") in connection with (i) any action,
suit or proceeding that may be instituted or (ii) any claim that may be asserted
by any Person not a party to this Agreement, the party seeking indemnification
hereunder (the "Indemnified Party") shall promptly cause written notice of the
assertion of such Indemnification Claim to be delivered to the party from whom
indemnification hereunder is sought (the "Indemnifying Party") prior to the
expiration of the applicable survival period set forth in Section 8.1; provided,
however, that no delay on the part of the Indemnified Party in giving any such
notice shall relieve the Indemnifying Party of any indemnification obligation
hereunder unless (and then solely to the extent that) the Indemnifying Party is
prejudiced by such delay. The Indemnifying Party shall have the right, at its
sole option and expense, to be represented by counsel of its choice, which must
be reasonably satisfactory to the Indemnified Party, and to defend against,
negotiate, settle or otherwise deal with any Indemnification Claim and, if the
Indemnifying Party elects to defend against, negotiate, settle or otherwise deal
with any Indemnification Claim, it shall within thirty (30) days (or sooner, if
the nature of the Indemnification Claim so requires) (the "Dispute Period")
notify the Indemnified Party of its intent to do so. If the Indemnifying Party
within the Dispute Period elects not to defend against, negotiate, settle or
otherwise deal with any Indemnification Claim, the Indemnified Party may defend
against, negotiate, settle or otherwise deal with such Indemnification Claim. If
the Indemnifying Party assumes the defense of any Indemnification Claim, the
Indemnified Party may participate, at its own expense, in the defense of such
Indemnification Claim; provided, however, that such Indemnified Party shall be
entitled to participate in any such defense with separate counsel at the expense
of the Indemnifying Party if (x) so requested by the Indemnifying Party to
participate or (y) in the reasonable opinion of counsel to the Indemnified
Party, a conflict or potential conflict exists between the Indemnified Party and
the Indemnifying Party that would make such separate representation advisable;
and provided, further, that the Indemnifying Party shall not be required to pay
for more than one such counsel for all Indemnified Parties in connection with
any single Indemnification Claim. The parties hereto agree to cooperate fully
with each other in connection with the defense, negotiation or settlement of any
such Indemnification Claim arising out of a third party claim. Notwithstanding
anything in this Section 8.4 to the contrary, neither the Indemnifying Party nor

                                                                            -32-



                                                                  Execution Copy

the Indemnified Party shall, without the written consent of the other party,
settle or compromise any Indemnification Claim or permit a default or consent to
entry of any judgment unless the claimant and such party provide to such other
party an unqualified release from all liability in respect of the
Indemnification Claim. Notwithstanding the foregoing, if a settlement offer
solely for money damages is made by the applicable third party claimant, and the
Indemnifying Party notifies the Indemnified Party in writing of the Indemnifying
Party's willingness to accept the settlement offer and, subject to the
applicable limitations of Section 8.5, pay the amount called for by such offer,
and the Indemnified Party declines to accept such offer, the Indemnified Party
may continue to contest such Indemnification Claim, free of any participation by
the Indemnifying Party, and the amount of any ultimate liability with respect to
such Indemnification Claim that the Indemnifying Party has an obligation to pay
hereunder shall be limited to the lesser of (i) the amount of the settlement
offer that the Indemnified Party declined to accept plus the Losses of the
Indemnified Party relating to such Indemnification Claim through the date of its
rejection of the settlement offer or (ii) the aggregate Losses of the
Indemnified Party with respect to such Indemnification Claim. If the
Indemnifying Party makes any payment on any Indemnification Claim, the
Indemnifying Party shall be subrogated, to the extent of such payment, to all
rights and remedies of the Indemnified Party to any insurance benefits or other
claims of the Indemnified Party with respect to such Indemnification Claim.

                  (b) In the event that an Indemnified Party has any claim
against an Indemnifying Party hereunder, but which such claim does not involve
an action, suit, proceeding or claim by a third party not party to this
Agreement, which such Indemnified Party determines to assert, then such
Indemnified Party shall assert such Indemnification Claim by sending written
notice to the Indemnifying Party describing in reasonable detail the nature of
such claim and the Indemnified Party's estimate of the amount of Losses
attributable to such claim.

                  (c) After any final and non-appealable decision, judgment or
award shall have been rendered by a Governmental Entity of competent
jurisdiction, or a settlement or arbitration shall have been consummated, or the
Indemnified Party and the Indemnifying Party shall have arrived at a mutually
binding agreement (any such event a "Final Determination") with respect to any
Indemnification Claim hereunder, then the Indemnifying Party shall pay any
amount so determined to such Indemnified Party.

         Section 8.5       Limitations on Indemnification for Breaches of
Representations and Warranties.

                  (a) Notwithstanding the provisions of this Article VIII, (i)
no Indemnifying Party shall have any indemnification obligations for Losses
under this Article VIII unless and until the aggregate amount of all such Losses
exceeds one hundred thousand dollars ($100,000) (the "Basket Amount"); provided,
however, that from and after such time as the total amount of Losses under this
Article VIII exceeds the Basket Amount then the Indemnifying Party shall be
liable only for the amount that exceeds the Basket Amount. Each of the
Shareholders shall be liable for all Indemnification Claims made under Section
8.2(a) up to the Shareholder's Pro Rata Percentage of the Indemnification Claim.
Notwithstanding the above, the Basket Amount shall not apply to: (i) Purchaser's
payment of the Purchase Price under Section 1.3; (ii) the obligations of the
parties regarding Working Capital and the adjustment of the Purchase Price under
the provisions of Section 1.4(e); (iii) the Purchaser's obligation to make the
Option Cash Out Contribution under Section 1.6; (iv) the Shareholders'
obligation under Section 6.6(b) to pay Taxes as set forth therein; and (v) a
claim for indemnification made under Section 8.2(b).

                                                                            -33-



                                                                  Execution Copy

                  (b) In no event shall the aggregate indemnification to be paid
by the Indemnifying Party under this Article VIII, exceed the following amounts
(the "Cap" ):

                           (i) there shall be no limit to the amount to be paid
         by an Indemnifying Party under the Article VIII regarding
         Indemnification Claims arising out of or relating to fraudulent acts or
         inactions or intentional misrepresentations of the Indemnifying Party;

                           (ii) breaches of or the falsity of the
         representations, warranties and covenants contained in Section 3.1
         (Company Organization), Section 3.2 (Company Capitalization), Section
         3.3 (Company No Violation), Section 3.9 (Company Taxes), Section 4.1
         (Shareholder Authority), Section 4.2 (Shareholder No Violation),
         Section 4.4 (Shareholder Stock Ownership), Section 5.1 (Purchaser
         Organization), Section 5.2 (Purchaser Authority), Section 5.3
         (Purchaser No Violation), and Section 6.6 (Post-Closing Tax Matters)
         shall be limited in amount to the Purchase Price; and

                           (iii) all other breaches of or the falsity of
         representations, warranties and covenants in the Agreement shall be
         limited in amount to $3,000,000.

                  (c) Losses subject to indemnification or reimbursement under
Article VIII shall not include any incidental or consequential damages,
including lost or anticipated profits, except to the extent such damages are
payable by an Indemnified Party to a third party.

         Section 8.6       Calculation of Losses.

                  The amount of any Losses for which indemnification is provided
under this Article VIII shall be net of any amounts actually recovered or
recoverable by the Indemnified Party under insurance policies or otherwise with
respect to such Losses but shall not be reduced by the net present value of any
Tax benefits realized or expected to be realized by the Indemnified Party. The
Indemnified Party shall use its commercially reasonable efforts to mitigate any
Losses and recover under insurance policies or otherwise for any Losses.

         Section 8.7       Tax Treatment of Indemnity Payments.

                  The Shareholders and Purchaser agree to treat any indemnity
payment made pursuant to this Article VIII as an adjustment to the Purchase
Price for federal, state, local and foreign income tax purposes.

                                                                            -34-



                                                                  Execution Copy

         Section 8.8       Subrogation.

                  Upon making any payment for Losses of an Indemnified Party
under this Article VIII, the Indemnifying Party will, to the extent of such
payment, be subrogated to all rights of the Indemnified Party against any third
party with respect to the Loss for which the payment relates. In addition to any
other obligation under this Agreement, the Indemnified Party agrees to duly
execute and deliver, upon request of the Indemnifying Party, all instruments
reasonably necessary to evidence and perfect the subrogation and subordination
rights granted pursuant to this Section 8.8.

         Section 8.9       Exclusive Remedy.

                  From and after Closing, except in the event of fraud, the sole
and exclusive remedy for any breach, or alleged breach, of any representation or
warranty or any covenant or agreement in this Agreement, shall be
indemnification in accordance with this Article VIII. Notwithstanding the
foregoing, this Section 8.9 shall not operate to limit the rights of the parties
to seek equitable remedies (including specific performance or injunctive
relief).

         Section 8.10      Release.

                  Effective upon Closing, except with respect to a claim arising
out of this Agreement (including without limitation Section 6.15 and Section 8.3

any right to recover against the Company for any indemnification claims made
against or paid by Shareholders pursuant to this Article VIII. Notwithstanding
anything to the contrary in this Section 8.10, in no event shall anything in

controlling person, director, officer, employee, agent or other representative
of the Company or any of its Subsidiaries with respect to any claim brought by
Purchaser against Shareholders pursuant to this Article VIII.

                                                                            -35-

         Section 9.3       Interpretation.

                  When a reference is made in this Agreement to "Sections,"
"Exhibits" or the "Company Disclosure Schedules," such reference shall be to a
section of, an exhibit of, or the Company Disclosure Schedules to, this
Agreement unless otherwise indicated. The table of contents and headings
contained in this Agreement are for reference purposes only and shall not affect
in any way the meaning or interpretation of this Agreement. Whenever the words
"include," "includes" or "including" are used in this Agreement, they shall be
deemed to be followed by the words "without limitation." The terms defined in
the singular have a comparable meaning when used in the plural, and vice versa,
and references herein to any gender includes each other gender. Shareholders
may, at their option, include in the Company Disclosure Schedules items that are
not material in order to avoid any misunderstanding, and such inclusion, or any
references to dollar amounts, shall not be deemed to be an acknowledgement or
representation that such items are material, to establish any standard of
materiality or to define further the meaning of such terms for purposes of this
Agreement. Any fact disclosed in a particular item or schedule of the Company
Disclosure Schedules shall be deemed to be a fact disclosed in each other item
and schedule of the Company Disclosure Schedules to which the applicability of
such disclosure is readily apparent on its face.

                                                                            -37-

         Section 9.4       Counterparts.

                  This Agreement may be executed in one or more counterparts,
including facsimile counterparts, all of which shall be considered one and the
same agreement and shall become effective when counterparts have been signed by
each of the parties and delivered to the other parties.

         Section 9.5       Entire Agreement; Construction.

                  This Agreement (including the disclosure schedules, annexes
and exhibits hereto and the other instruments referred to herein) constitute the
entire agreement and supersedes all prior agreements and understandings, both
written and oral, among the parties with respect to the subject matter hereof.
The parties have participated jointly in the negotiation and drafting of this
Agreement. In the event an ambiguity or question of intent or interpretation
arises, this Agreement shall be construed as if drafted jointly by the parties
and no presumption or burden of proof shall arise favoring or disfavoring any
party by virtue of the authorship of any of the provisions of this Agreement.

         Section 9.6       Amendment; Shareholder Majority.

                  This Agreement may not be amended except by an instrument in
writing signed by Purchaser and a Shareholder Majority. Whenever any consent,
waiver, agreement or other action of the Shareholders as a group is required or
permitted under the this Agreement, such action will only be effective if it is
taken with the consent of a Shareholder Majority; provided, however, that the
written consent of a Shareholder will always be required to amend this Agreement
in order to (a) subject such Shareholder to any additional obligations that are
disproportionate to any additional obligations imposed on the Shareholder
Majority; or (b) reduce the amount of the Purchase Price owed to such
Shareholder; and further provided, that this Section may not be amended without
the unanimous consent of the Shareholders.

         Section 9.7       Extension; Waiver.

                  The Purchaser or a Shareholder Majority hereto may, to the
extent legally allowed, (a) extend the time for the performance of any of the
obligations or other acts of the other parties hereto, (b) waive any
inaccuracies in the representations and warranties contained herein or in any
document delivered pursuant hereto, and (c) waive compliance with any of the
agreements or conditions contained herein. Any agreement on the part of a party
hereto to any such extension or waiver shall be valid only if set forth in a
written instrument signed on behalf of such party, but such extension or waiver
or failure to insist on strict compliance with an obligation, covenant,
agreement or condition shall not operate as a waiver of, or estoppel with
respect to, any subsequent or other failure.

                                                                            -38-

Agreement or any of the transactions contemplated hereby, and each party hereby
irrevocably agrees that all claims in respect of such dispute or any suit,
action or proceeding related thereto may be heard and determined in such courts.
The parties hereby irrevocably waive, to the fullest extent permitted by
applicable Law, any objection which they may now or hereafter have to the laying
of venue of any such dispute brought in such court or any defense of
inconvenient forum for the maintenance of such dispute. Each of the parties
hereto agrees that a judgment in any such dispute may be enforced in other
jurisdictions by suit on the judgment or in any other manner provided by Law.

                  (b) Each of the parties hereto hereby consents to process
being served by any party to this Agreement in any suit, action or proceeding by
the delivery of a copy thereof in accordance with the provisions of Section 9.2.

         Section 9.10      Severability.

                  Any term or provision of this Agreement which is invalid or
unenforceable in any jurisdiction shall, as to that jurisdiction, be ineffective
to the extent of such invalidity or unenforceability without rendering invalid
or unenforceable the remaining terms and provisions of this Agreement or
affecting the validity or enforceability of any of the terms or provisions of
this Agreement in any other jurisdiction. If any provision of this Agreement is
so broad as to be unenforceable, the provision shall be interpreted to be only
so broad as is enforceable.

         Section 9.11      Assignment.

                  Neither this Agreement nor any of the rights, interests or
obligations hereunder shall be assigned by any of the parties hereto (whether by
operation of law or otherwise) without the prior written consent of the other
parties. Subject to the preceding sentence, this Agreement will be binding upon,
inure to the benefit of and be enforceable by the parties and their respective,
heirs, successors and assigns.

         Section 9.12      No Third Party Beneficiaries.

                  This Agreement is for the sole benefit of the parties hereto
and their permitted assigns, and nothing herein expressed or implied shall give
or be construed to give any Person, other than the parties hereto and such
assigns, any legal or equitable rights hereunder, except to the extent expressly
set forth in Section 6.15 and Article VIII. All references herein to the
enforceability of agreements with third parties, the existence or non-existence
of third party rights, the absence of breaches or defaults by third parties, or
similar matters or statements, are intended only to allocate rights and risks
among the parties hereto and are not intended to be admissions against
interests, give rise to any inference or proof of accuracy, be admissible
against any party hereto by any third party, or give rise to any claim or
benefit to any third party.

                                                                            -39-
