as provided hereinbelow in this Section 2.2) (referred to as the "Cash Portion
of the Purchase Price"), and (ii) the WEI Shares (valued at $6.00 per share).
The aggregate of the Purchase Price and the amount of Company Debt at the time
of Closing shall equal $2,250,000.00, plus an adjustment for any increase or
decrease in the Company's net book value as of the closest month-end that is not
less than fifteen (15) days prior to Closing compared to the Company's net book
value existing at December 31, 1999, as reflected in its audited year-end
financials (the "NBV Adjustment"). The Purchase Price for the VVI Shares shall
be reduced or increased dollar for dollar for (i) any Debt of the Company
existing as of the Closing Date, in excess of or less than $900,000.00, as the
case may be, and (ii) the NBV Adjustment; accordingly, as the value of the WEI
Shares is agreed upon to be $500,000.00, any adjustment in the Purchase Price
shall be reflected in the Cash Portion of the Purchase Price. (E.g., if the
aggregate Debt of the Company at Closing is equal to $940,000.00, the Purchase
Price of the VVI Shares shall be $1,310,000.00, which shall be represented by
the WEI Shares and the Cash Portion of the Purchase Price equal to $810,000.00;
in the alternative, if the aggregate Debt of

                                       3

<PAGE>

the Company is equal to $860,000.00, the Purchase Price of the VVI Shares shall
be $1,390,000.00, which shall be represented by the WEI Shares and the Cash
Portion of the Purchase Price equal to $890,000.00. The foregoing example would
then take into consideration the NBV Adjustment.) In addition to the foregoing,
the Cash Portion of the Purchase Price required to be delivered at Closing shall
be reduced by the earnest money payments made by Purchaser to Sellers, as
described in Section 2.4 hereof.

     2.3 ADDITIONAL ACTIONS AT CLOSING. In addition to the purchase and sale of
the VVI Shares, at Closing, Purchaser and Joseph Duke shall deliver those items
required in Sections 3.2 and 3.3 hereof.

     2.4 EARNEST MONEY PAYMENTS. In order to induce Sellers to enter into this
Agreement and to proceed diligently to Closing, Purchaser has paid Sellers
$25,000 in cash on January 21, 2000, $8,333 in cash on April 28, 2000, $8,333 on
May 20, 2000, and $8,333 on June 20, 2000. In addition, Purchaser shall pay to
Sellers in cash an additional $25,000 on or before September 8, 2000, which then
also shall adjust the Cash Portion of the Purchase Price to be delivered at
Closing. So long as Sellers proceed to Closing diligently and in good faith, and
so long as the transactions described in this Agreement shall not have been
terminated due to the actions of Sellers in violation of this Agreement, all of
the payments to Sellers specified in this Section 2.4 are nonrefundable and
Sellers shall have no obligation to refund these payments to the Purchaser. All
earnest money payments described in this Section 2.4 shall be credited towards
the Cash Portion of the Purchase Price, thereby reducing the amount of cash
required by Purchaser at Closing.

any charter, bylaw, mortgage, lien, lease, license, permit, agreement, contract,
instrument, law, rule, ordinance, regulation, order, judgment or decree, or
other restriction of any kind or character (other than laws and regulations
generally applicable to similar businesses), that materially adversely affects

assets or property, or that would prevent consummation of the transactions
contemplated by this Agreement, compliance by Sellers with the terms, conditions
and provisions hereof or thereof or the continued operation of the Company's
business after the date hereof on substantially the same basis as heretofore
operated.

     4.11 COMPLIANCE WITH LAWS. The Company is and at all times has been in

marks, trade names, patents, assumed or fictitious names, logos, trade secrets,
know-how and other proprietary rights and applications therefor and
registrations thereof that are material to the conduct of the business of the
Company (collectively, "Proprietary Rights"). The Company has a right to use
such proprietary rights in connection with its business as presently being

the rights of any third party. To the best of Sellers' knowledge, all
Proprietary Rights of the Company are free from any claim of others, security
interest, lien, encumbrance or restriction, there is no default with respect
thereto on the part of the

                                       8

Company, and such Proprietary Rights have not been and are not now being
challenged in any way or involved in any pending or threatened infringement,
unfair competition or other proceeding. To the best of Sellers' knowledge, the
Company is not infringing the rights of any other Person with respect to any
Proprietary Right and has not received any claim of any such infringement or

     (a) The Company (i) has duly and timely filed with the appropriate
governmental authorities all tax returns and reports required to be filed and
(ii) has duly paid all taxes, interest, penalties, assessments and deficiencies
and other governmental charges which are due and payable upon it and its
properties, assets, income, business, sales and payrolls, including all amounts
assessed as additional taxes, penalties and interest.

     (b) The Company has not been audited by the IRS during the past five (5)
years. The Company has not executed or filed with the IRS or any other taxing
authority any agreement extending the period for assessment or collection of any
income or other taxes.

     (c) The Company is not a party to any pending action or proceeding nor, to
the best of Sellers' knowledge, is any action or proceeding threatened by any
governmental authority for assessment or collection of taxes, and, to the best
of Sellers' knowledge after investigation, no claim for assessment or collection
of taxes has been asserted against the Company.

     (d) To the best of Sellers' knowledge after investigation, the Company has
withheld proper and accurate amounts from its employees in full and complete
compliance with all withholding and similar provisions of the Code and any and
all other applicable United States, foreign, state or local laws, statutes,
codes, ordinances, rules and regulations. To the best of Sellers' knowledge
after investigation, the Company has timely filed the proper federal, foreign,
state and local returns, reports and estimates with respect to employee income
tax withholding, social security taxes and unemployment taxes (or comparable or
similar taxes or charges) for all years and periods (or portions thereof) for
which such returns and reports were due, and any and all amounts that were due

     4.16 EMPLOYEES/EMPLOYEE BENEFIT PLANS. Schedule 4.16 sets forth a correct
and complete list of all current employees of the Company, and all employee
benefit plans (collectively, the "Plans") maintained by the Company, in which it
participates or may be required to participate or in respect of which it may
have any liability. Except for the Plans, the Company does not have in effect,
participate in, or have any liability for any plan, fund or program as defined
in Section III(2) of the Employee Retirement Income Act of 1974, as amended
("ERISA"), and does not have an obligation to establish any such plan, fund or
program. Sellers have furnished Purchaser with true and complete copies of all
of the Plans and the latest financial statements therefor, if any, which fairly
represent the financial condition of the Plans at such dates. There have been no
materially adverse changes to any of the Plans since the date of the latest
financial statements, if any. To the best of Sellers' knowledge after
investigation, there is not outstanding any request for information concerning
the Plans by participants, beneficiaries or government agencies. Neither the
Company nor the Plans have been involved in any transaction that would
constitute a "prohibited transaction" within the meaning of Sections 503 and
4975 of the Code or ERISA Section 406. None of the Plans has any "accumulated
funding deficiency" as described in Code Section 412, and all required
contributions to the Plans for the period through the Closing Date have been
made. All Plans are in compliance in all material respects with the applicable
provisions of ERISA, the regulations issued thereunder and all other applicable
statutes and regulations. To the extent the Plans are administered by the
Company, such Plans have been maintained and administered in accordance with
their separate terms. Each Plan which is intended to qualify under Code Section
401 has been issued a determination letter by the IRS that it is qualified under
Code Section 401(a) and its trust fund is exempt from taxation under Code
Section 501(a). All information submitted with the request for such
determination letters, if any, was true and accurate in all material respects,
all material information required to have been submitted to the IRS was
submitted, and no event has occurred with respect to any Plan that would cause
the loss of such qualification. Each trust fund established for any medical or
disability plan has been issued a determination letter by the IRS that it is
exempt from taxation under Code Section 501(c)(9), and no event has occurred
with respect to any such Plan that would cause the loss of such qualification.
None of the Plans has experienced a "reportable event" as described in ERISA
Section 4043(b) or is experiencing any condition that may constitute grounds
under ERISA Section 4042 for the termination of such Plan or the appointment of
a trustee to administer such Plan. The Company has not (i) contributed or been
required to contribute to any "multi-employer pension plan," as that term is
defined in ERISA Section III(37)(A), or (ii) incurred any withdrawal liability
under subtitle E of Title IV of ERISA or has withdrawn from any multi-employer
pension plan in any manner that could result in any liability to the Company.

     4.17 CONDUCT OF BUSINESS. Between June 30, 2000, and the date of this
Agreement, except as otherwise approved by the Purchaser in writing, the
business of the Company has been conducted only in the ordinary course and there
has occurred no materially adverse change or, to the knowledge of Sellers, any
event that involved any significant possibility of a materially adverse change,
in the condition (financial or otherwise), assets, liabilities, business,
operations or affairs of the Company. (See Schedule 4.17 hereto.)

     4.18 SOLVENCY. The sale and transfer of the VVI Shares pursuant to this
Agreement will not render Sellers insolvent (within the meaning of the Uniform
Fraudulent Conveyance Act or 11 U.S.C.ss. 101(31)).

leases under which the Company leases, as lessor or lessee, any real or personal
property along with the names of the parties to such leases, the commencement
and expiration dates of such leases and a summary description of the rental
under such leases and any options pertaining thereto. Except as described in
Schedule 4.19, all such leases are in full and force and effect, in all material
respects, and no party thereto is in material default or breach thereunder.

complete list and summary description of all real and material personal
property, tangible or intangible (other than inventory), owned by the Company

4.20 or in other Schedules to this Agreement, the Company owns the property set
forth in Schedule 4.20 free and clear of all liens, charges, mortgages, security
interests, pledges and encumbrances of any nature whatsoever. Substantially all
such tangible personal property is in satisfactory condition and is suitable for
the purpose for which it is being used, subject in each case to consumption in
the ordinary course, to ordinary wear and tear and to ordinary repair,
maintenance and periodic replacement.

     4.21 MATERIAL CONTRACTS. Schedule 4.21 sets forth, unless set forth in
another Schedule hereto, a correct and complete list as of the date hereof of
all written or material oral agreements, contracts and commitments of the
following types to which the Company or by which the Company is bound or
otherwise affected as of the date hereof, including, without limitation: (i)
mortgages, indentures, security agreements, loan and credit agreements and other
agreements and instruments relating to the borrowing of money or evidence of
credit, (ii) contracts or options to purchase or sell real property, (iii)
contracts for the purchase or sale of materials, supplies or equipment or for
providing services, that individually involve payments to be made of more than
$1,000, (iv) contracts between the Company and any Seller, (v) agreements and
instruments representing loans or commitments to loan to officers, directors,
employees or agents of the Company, (vi) contracts of any kind to which the
United States Government or any of its agencies or any state or local
municipality is a party or under which the Company is a contractor or
subcontractor under any federal, state or local law, regulation or executive
order, (vii) partnership or joint venture agreements of any kind, (viii)
management, employment, consulting, service and independent contractor
agreements, (ix) development, production, financing and similar agreements, (x)
license agreements, (xi) confidentiality and nondisclosure agreements, (xii)
agreements relating to a merger or to the acquisition or disposition of stock or
assets, (xiii) distribution agreements, and (xiv) other agreements, contracts
and commitments (other than those previously set forth in Schedules hereto).
Sellers have delivered or made available to Purchaser complete and correct
copies of all such written agreements, contracts and commitments, together with
all amendments thereto and waivers and consents with respect thereto. Except as
disclosed in Schedule 4.21 hereto, all of such agreements, contracts and
commitments referred to are in full force and effect and all parties to such
agreements, contracts and commitments have performed in all material respects
all of the obligations required to be performed by them to date and are not in
default thereunder in any material respect. No agreement, contract or commitment
to which the Company is a party, or by which it or any of its properties is
bound, specifically limits its freedom to compete in any line of business or
with any person or entity.

Company has and is in substantial compliance with all material permits,
licenses, orders and approvals of all federal, state, local or foreign
governmental or regulatory bodies required for it to carry out its business as
presently conducted, all of which are listed in Schedule 4.22. All such permits,
licenses, orders and approvals are in full force and effect, and no suspension
or cancellation, nor any proposed adverse modification of any of them is pending
or, to the knowledge of Sellers, threatened. No consent of any governmental or
regulatory body issuing such permits, licenses, orders and approvals is
necessary for the consummation of the transactions contemplated by this
Agreement, the failure of which to so obtain would result in a material adverse
effect on the transactions contemplated hereby.

     4.23 TITLE TO PROPERTIES. The Company has good and marketable (as to real
estate, if any) title to all of the properties and assets reflected in the June
30, 2000 balance sheet as owned by it (other than assets disposed of in the

liens, mortgages, encumbrances and similar claims (Liens") other than (a) Liens
reflected in such financial statements and notes, (b) Liens for taxes and
betterment assessments contested in good faith in appropriate proceedings or
that are not yet due and payable, (c) Liens reflected in Schedule 4.23, and (d)
and such other Liens, if any, as do not materially detract from the value of or
interfere with the present or future use of the properties or assets affected
thereby.

     4.24 INSURANCE. Set forth in Schedule 4.24 hereto is a complete list of
insurance policies that the Company maintains with respect to its businesses,
properties or employees. Such policies are in full force and effect free from
any right of termination on the part of the insurance carriers. Since June 30,
2000, there has not been any material adverse change in the Company's
relationship with its insurers or in the premiums payable pursuant to such
policies.

         4.25 ACCOUNTS RECEIVABLE. Set forth in Schedule 4.25 hereto is a
complete list of the Company's accounts receivables, unbilled invoices and other
debts due to the Company (the "Accounts Receivable") as of June 30, 2000. Except

goods and services involved have been sold, delivered and performed to the
account of the Company, and no further goods are required to be provided and no
further services are required to be rendered by the Company to collect the
Accounts Receivable in full. No such account has been assigned or pledged to any

     4.38 INVESTMENT REPRESENTATION. The WEI Shares are being acquired for the
account of Sellers and not with a view to, nor for sale in connection with, any
distribution thereof, and without any present intention of selling the same. The
WEI Shares will not be sold or otherwise disposed of in the absence of a
registration statement under the Securities Act of 1933, as amended (the
"Securities Act"), covering the WEI Shares, respectively, or an exemption from
the registration requirements of the Securities Act.

     Sellers hereby acknowledge that (i) the WEI Shares may not be sold or
otherwise transferred unless they are registered under the Securities Act or an
exemption from such registration is available; (ii) any sales of the WEI Shares
made in reliance upon Rule 144 promulgated under the Securities Act can be made
only in accordance with the terms and conditions of Rule 144 and, further, that
if Rule 144 is not applicable, any resale of such securities under circumstances
in which Sellers or the person through whom the sale is made may be deemed to be
an underwriter, as that term is defined in the Securities Act, may require
compliance with some other exemption under the Securities Act or the rules and
regulations of the Securities and Exchange Commission or other governmental
authority substituted therefor; and (iii) Purchaser is under no obligation to
register any of the WEI Shares under the Securities Act or to comply with the
terms and conditions of any exemption thereunder.

     The instruments evidencing the WEI Shares may bear a restrictive legend in
substantially the following form (and a stop-transfer order may be placed
against transfer thereof):

     THE SECURITIES REPRESENTED HEREBY WERE NOT REGISTERED UNDER, AND ARE
     SUBJECT TO, THE SECURITIES ACT OF 1933, AS AMENDED (THE "1933 ACT"),
     AND MAY NOT BE SOLD, TRANSFERRED OR ASSIGNED, AND THE COMPANY IS NOT
     REQUIRED TO GIVE EFFECT TO ANY ATTEMPTED SALE, TRANSFER OR ASSIGNMENT,
     EXCEPT (I) PURSUANT TO A CURRENT REGISTRATION UNDER THE 1933 ACT; (II)
     IN A TRANSACTION PERMITTED BY RULE 144 UNDER THE 1933 ACT AND AS TO
     WHICH THE COMPANY HAS RECEIVED REASONABLY SATISFACTORY EVIDENCE OF
     COMPLIANCE WITH THE PROVISIONS OF RULE 144; OR (III) UPON RECEIPT OF A
     LEGAL OPINION RENDERED BY COUNSEL REASONABLY SATISFACTORY TO THE
     COMPANY TO THE EFFECT THAT THE TRANSACTION DOES NOT REQUIRE
     REGISTRATION UNDER THE 1933 ACT.

     If a legal opinion complying with clause (iii) of the legend set forth
above indicates that the legend and stop-transfer order may be removed,
Purchaser will substitute unlegended instruments for and remove the
stop-transfer order from the instruments described in the opinion.

     In connection with any Purchaser IPO (as defined in Section 10.11 hereof)
or any other offering involving an underwriting of shares being issued by
Purchaser, Purchaser shall not be required to include any of the WEI Shares in
such underwritings unless other shareholders of

                                       15

<PAGE>

Purchaser are being permitted to include some or all of their shares in the
underwritings, in which case Sellers shall be permitted to include some or all
of the WEI Shares on an equivalent basis; however, should Purchaser agree to
include a portion of the WEI Shares in such underwriting, following Sellers'
request to do so, Sellers must accept the terms of the underwriting (to the
extent applicable to the WEI Shares) as agreed upon between Purchaser and the
underwriters selected by Purchaser (all costs of registering the WEI Shares
shall be borne by Purchaser). Furthermore, in connection with any registration
of the WEI Shares, Sellers agree, if requested by Purchaser or the underwriters
managing any underwritten offering of the WEI Shares, not to sell, make any
short sale of, loan, grant any option for the purchase of, or otherwise dispose
of any of the WEI Shares (other than that included in the registration) without
the prior written consent of Purchaser or such underwriters, as the case may be,
for such period of time after the effective date of such registration as
Purchaser or the underwriters may specify, which, in any event, shall be a
minimum of twelve (12) months following any Purchaser IPO; but in any event
shall be no longer than the time period required by the underwriter for
similarly situated shareholders and senior management of Purchaser. Sellers
shall receive treatment no less favorably than any other shareholder of
Purchaser at the time of any offering involving an underwriting of shares being
issued by Purchaser.

satisfactory to Sellers. In any event, at Closing, Purchaser shall cause the

              ARTICLE 10 -- SURVIVAL OF REPRESENTATIONS; INDEMNITY

     10.1 SURVIVAL OF REPRESENTATIONS. The respective representations and
warranties of the parties contained in this Agreement or in any Schedule
delivered pursuant hereto shall survive the consummation of the transactions
contemplated hereby and continue for a period of two (2) years thereafter;
provided, however, that all representations and warranties of Sellers relating
to ownership of the VVI Shares shall continue indefinitely.

     10.2 INDEMNIFICATION BY SELLERS. Sellers shall indemnify Purchaser, its
Affiliates and their respective officers, directors and agents (collectively,
the "Purchaser Indemnified Parties") against and hold them harmless from all
damages, losses, expenses, claims, demands, suits, causes

                                       25

<PAGE>

of action, proceedings, judgments and liabilities, including reasonable counsel
fees and court costs, assessed, incurred or sustained by or against the
Purchaser Indemnified Parties or the Company with respect to or arising out of
(i) the failure of any representation or warranty made by Sellers in this
Agreement or in any Schedule delivered pursuant hereto to be true and correct in
all material respects as of the date of this Agreement and as of the Closing
Date, (ii) the failure of Sellers to fulfill any of their covenants or
agreements hereunder, and (iii) any action or inaction of the Company prior to
the Closing Date (collectively, "Seller Liabilities"). With respect to those
matters covered in (iii) in the immediately preceding sentence, the
indemnification shall be limited to such amounts that are in excess of
liabilities accrued on the closing balance sheet used for calculating the
Company's net book value as referred to in the second sentence of Section 2.2
hereof.

     10.3 INDEMNIFICATION BY PURCHASER. Purchaser shall indemnify Sellers and
Sellers' agents (collectively, the "Seller Indemnified Parties") against and
hold them harmless from all damages, losses, expenses, claims, demands, suits,
causes of action, proceedings, judgments and liabilities, including reasonable
counsel fees and court costs, assessed, incurred or sustained by or against the
Seller Indemnified Parties with respect to or arising out of (i) the failure of
any representation or warranty made by Purchaser in this Agreement to be true
and correct in all material respects as of the date of this Agreement and as of
the Closing Date, (ii) the failure of Purchaser to fulfill any of its covenants
or agreements contained herein, and (iii) any action or inaction of the Company
after the Closing Date.

     10.4 REDUCTION OF PAYMENTS. If a payment by either party gives rise to a
loss, damage or expense that is subject to indemnification by the other party
hereto, the amount for which the damaged party may receive indemnification shall
be reduced by any insurance proceeds or other payments received by the damaged
party in respect thereof.

     10.5 INDEMNIFICATION OF THIRD-PARTY CLAIMS. The obligations and liabilities
of any party to indemnify any other under this Article 10 with respect to claims
relating to third parties ("Claims") shall be subject to the following terms and
conditions:

     (a) NOTICE AND DEFENSE. The party or parties to be indemnified (whether one
or more, the "Indemnified Party") will give the party from whom indemnification
is sought (the "Indemnifying Party") prompt written notice of any such Claim,
and the Indemnifying Party will undertake the defense thereof by representatives
chosen by it. So long as the Indemnifying Party is defending any such Claim
actively and in good faith, the Indemnified Party shall not settle such Claim.
The Indemnified Party shall make available to the Indemnifying Party or its
representatives all records and other materials required by them and in the
possession or under the control of the Indemnified Party, for the use of the
Indemnifying Party and its representatives in defending any such Claim, and
shall in other respects give reasonable cooperation in such defense.

     (b) FAILURE TO DEFEND. If the Indemnifying Party, within a reasonable time
after notice of any such Claim, fails to defend such Claim actively and in good
faith, the Indemnified Party will (upon further notice) have the right to
undertake the defense, compromise or settlement of such Claim or consent to the
entry of a judgment with respect to such Claim, on behalf of and for the account
and risk of the Indemnifying Party, and the Indemnifying Party

                                       26

<PAGE>

shall thereafter have no right to challenge the Indemnified Party's defense,
compromise, settlement or consent to judgment therein.

     (c) INDEMNIFIED PARTY'S RIGHTS. Anything in this Section 10.5 to the
contrary notwithstanding, (i) if there is a reasonable probability that a Claim
may materially and adversely affect the Indemnified Party other than as a result
of money damages or other money payments, the Indemnified Party shall have the
right to defend, compromise or settle such Claim, and (ii) the Indemnifying
Party shall not, without the written consent of the Indemnified Party, settle or
compromise any Claim or consent to the entry of any judgment which does not
include as an unconditional term thereof the giving by the claimant or the
plaintiff to the Indemnified Party of a release from all Liability in respect of
such Claim.

     10.6 TIME FOR NOTICE. Any party claiming indemnification hereunder with
respect to the falsity of any representations or warranties herein must give
notice to the other party of its claim for indemnification within the time
period, if any, specified in Section 10.1 hereof for the survival of the
applicable representation or warranty.

     10.7 TIME FOR PAYMENT. All indemnification payments required to be made
pursuant to this Article 10 shall be made promptly after demand for payment has
been made by the indemnified party upon the indemnifying party.

     10.8 TAX EFFECT. The indemnification obligation of an Indemnifying Party
shall be adjusted so as to give effect to any net reduction in federal, state,
local or foreign income or franchise tax liability actually realized at any time
by the Indemnified Party in connection with the satisfaction by the Indemnifying
Party of the Claims with respect to which indemnification is sought hereunder.
Any Claims payable by the Indemnifying Party to the Indemnified Party hereunder
shall include the federal, state, local or foreign income or franchise tax
liability which the Indemnified Party will incur upon receipt of payment in
respect of such Claims (taking into account any net operating loss, capital loss
or credit carryover of the Indemnified Party). With respect to any Claims for
which the Indemnified Party (but for the operation of this sentence) is entitled
to indemnification hereunder, there shall be disregarded any tax liabilities
arising by reason of (i) any reduction or disallowance of deductions from
taxable income in one taxable year, to the extent such reduction or disallowance
would result in a corresponding increase in allowable deductions from income in
another taxable year, (ii) the shifting of items of income from one taxable year
to another, or (iii) the capitalization of amounts which were expensed, but only
if such capitalized amounts are subject to amortization or depreciation or
recovery in costs of goods sold, inventory or materials, except insofar as such
reduction, disallowance, shifting or capitalization would only result in the
increase of any unutilized net operating loss, capital loss or credit carryover.

     10.9 AMOUNT LIMITATION. An Indemnified Party shall not be entitled to
indemnification under this Article 10 for breach of a representation or warranty
unless the aggregate of the Indemnifying Party's indemnification obligations to
the Indemnified Party pursuant to this Article 10 (but for this Section 10.9)
exceeds $10,000; and in such event, the Indemnified Party shall only be entitled
to indemnification for the amount above such threshold. The Seller's total
liability shall not exceed the Purchase Price.

                                       27

<PAGE>

     10.10 INDEMNIFICATION IS SOLE REMEDY. Except as otherwise provided for
herein, the parties' sole and exclusive remedy for breach of this Agreement or
any claim or cause of action arising out of the transactions contemplated by
this Agreement is limited to the indemnification provisions of this Article 10.

     10.11 PURCHASER'S IPO. Purchaser anticipates that it will go public and
provide its initial public offering ("Purchaser's IPO") within sixty (60) days
of the date hereof, but not later than October 10, 2000 (the date of the
Purchaser's IPO shall be referred to herein as the "IPO Date"). Purchaser shall
take all reasonable steps to consummate Purchaser's IPO. Should Purchaser's IPO
not be offered at or prior to October 10, 2000, Sellers shall have the option
for a period of thirty (30) days commencing on October 10, 2000 to continue this
Agreement for an additional period specified in a notice of such continuation,
which period shall be not less than 30 days nor more than 120 days. Should
Sellers elect to continue this Agreement pursuant to the terms of this Section
10.11, Sellers shall provide Purchaser written notice to Purchaser five (5)
business days prior to October 10, 2000. If Sellers fail to provide such notice
to Purchaser, this Agreement shall terminate effective October 10, 2000.

                           ARTICLE 11 -- MISCELLANEOUS

     11.1 TERMINATION OF AGREEMENT. The parties hereto shall use all reasonable
efforts to consummate the transactions contemplated hereby as soon as
practicable. This Agreement may be terminated (i) at any time by mutual written
agreement of Sellers and Purchaser, (ii) by either Purchaser or Sellers if any
condition to the performance of the other party's obligations herein is not
fulfilled or waived on or prior to October 10, 2000, provided that no party in
breach of its obligations hereunder shall have the right to terminate this
Agreement, and this Agreement (other than the confidentiality provisions hereof)
shall be null and void and have no further effect. All rights or remedies of a
party that accrue as a result of the breach of any provision of the Agreement
shall survive any termination of this Agreement.

     11.2 EXECUTION IN COUNTERPARTS. For the convenience of the parties, this
Agreement may be executed in counterparts, each of which shall be deemed an
original, but all of which together shall constitute one and the same document.

waiver by either party taking such action of compliance with any representation,
warranty, covenant or agreement contained in this Agreement. The waiver by any
party hereto of a breach of any provision of this Agreement shall not operate or
be construed as a waiver of any subsequent breach.

     11.5 SPECIFIC PERFORMANCE. Each party hereto acknowledges and agrees that
the remedy at law for any breach of this Agreement would be inadequate, and
agrees and consents that temporary and permanent injunctive and other relief may
be granted without proof of actual damage or inadequacy of legal remedy in any

Agreement.

reason of this Agreement.

     11.9 ASSIGNABILITY. Neither this Agreement nor any of the parties' rights

obligations hereunder.

     11.10 EXPENSES. The parties hereto shall pay all of their own expenses
relating to the transactions contemplated by this Agreement, including, without
limitation, the fees and expenses of their respective counsel, accountants and
