                       NONSTATUTORY STOCK OPTION AGREEMENT

         THIS AGREEMENT is made effective June 13, 2003 ("EFFECTIVE DATE") by
and between VI Acquisition Corp., a Delaware corporation (the "COMPANY"), and
Robert Kaltenbach (the "OPTIONEE").

         WHEREAS, pursuant to the terms of that certain Stock Purchase Agreement
dated as of the 15th day of April, 2003 (the "PURCHASE AGREEMENT"), by and among
the Company, Midway Investors Holdings, Inc. ("MIDWAY"), the shareholders of
Midway and certain other parties, the Company is acquiring all of the
outstanding equity of Midway (the "TRANSACTION");

         WHEREAS, the Optionee will be retained as an employee of the Company or
one of its subsidiaries upon the consummation of the Transaction;

         WHEREAS, pursuant to the terms of the Purchase Agreement, the Optionee
has elected to exchange options to purchase shares of Midway's Class A Preferred
Stock, Class C Preferred Stock and Class B Common Stock (as such terms are
defined in the Purchase Agreement) having an aggregate Option Spread (as such
term is defined in the Purchase Agreement) of $447,205, for an option to
purchase shares of the Company's Preferred Stock, and the Company, to create an
incentive for the Optionee, has agreed to grant him an option upon certain terms
and conditions; and

         WHEREAS, the grant hereunder shall be independent of any formal stock
option plan to be maintained by the Company.

         NOW, THEREFORE, in consideration of the following mutual covenants and
for other good and valuable consideration, the parties agree as follows:

1.       GRANT OF OPTION

         The Company grants to the Optionee the right and option (the "OPTION")
         to purchase all or any part of an aggregate of 458.57 shares of the
         Company's Preferred Stock (the "SHARES") on the terms and conditions
         and subject to all the limitations set forth herein. The Optionee
         acknowledges that the definitive records pertaining to the grant of
         this Option, and exercises of rights hereunder, shall be retained by
         the Company. The Option granted herein is intended to be a nonstatutory
         option.

2.       PURCHASE PRICE

         The purchase price of the Shares subject to the Option shall be Twenty
         Four and 80/100 Dollars ($24.80) per Share.

3.       EXERCISE OF OPTION

         Subject to this Agreement, the Option shall be fully vested and
         exercisable on the Effective Date.

<PAGE>

         The Option shall expire on, and shall be exercised (if at all) prior to
         the first to occur of:

         (a)      June 12, 2013;

         (b)      Ninety (90) days after the date on which the Optionee shall
                  cease, for any reason or cause whatsoever, and without regard
                  to such reason or cause (except as set forth in (c) and (d)
                  below) to be an employee of, or consultant to, the Company or
                  any affiliate or subsidiary thereof;

         (c)      The date the Optionee's services are terminated, whether as an
                  employee or otherwise, if such services are terminated for Due
                  Cause (as such term is defined in that certain Employment
                  Agreement executed by and between the Employee and the Company
                  of even date herewith (the "EMPLOYMENT AGREEMENT")); or

         (d)      Twelve months from the date the Optionee's services are
                  terminated, whether as an employee or otherwise, if such
                  services are terminated as a result of the Optionee's death or
                  Permanent Disability (as such term is defined in the
                  Employment Agreement), in which case the Option may be
                  exercised by the Optionee or his legal representative or
                  estate within such twelve month period.

4.       ISSUANCE OF SHARES

         The Option may be exercised in whole or in part (to the extent that it
         is exercisable in accordance with its terms) by giving written notice
         (or any other approved form of notice) to the Company. Such written
         notice shall be signed by the person exercising the Option, shall state
         the number of Shares with respect to which the Option is being
         exercised and shall specify a date (other than a Saturday, Sunday or
         legal holiday) not less than five (5) nor more than ten (10) days after
         the date of such written notice, as the date on which the Shares will
         be purchased, at the principal office of the Company during ordinary
         business hours, or at such other hour and place agreed upon by the
         Company and the person or persons exercising the Option, and shall
         otherwise comply with the terms and conditions of this Agreement. On
         the date specified in such written notice (which date may be extended
         by the Company if any law or regulation requires the Company to take
         any action with respect to the Shares prior to the issuance thereof),
         the Company shall accept payment for the Shares and shall deliver to
         the Optionee an appropriate certificate or certificates for the Shares
         as to which the Option was exercised. The Optionee acknowledges and
         agrees that the Shares to be acquired upon exercise of the Option shall
         be subject to the Company's Stockholders' Agreement as in effect from
         time to time and the Management Agreement, and the issuance of Shares
         pursuant to the exercise of this Option shall be expressly conditioned
         upon the Optionee's execution of such agreements.

         The Option price of any Shares shall be payable at the time of exercise
         and shall only be payable through the Optionee's delivery to the
         Company of Shares that would otherwise be acquired upon the exercise of
         the Option (the "WITHHELD SHARES"). The fair market value of the number
         of Shares to be acquired by the Optionee upon exercise of the Option,
         net of the Withheld Shares, shall be equal to $447,205 (the "ACQUIRED
         SHARES")

                                       2
<PAGE>

         plus the value of Dividends (as provided for in Article 4 of the
         Amended and Restated Certificate of Incorporation of VI Acquisition
         Corp.) accrued on the Acquired Shares from the Effective Date.

         The Company shall pay all original issue taxes with respect to the
         issuance of Shares pursuant hereto and all other fees and expenses
         necessarily incurred by the Company in connection therewith. The holder
         of this Option shall have the rights of a stockholder only with respect
         to those Shares covered by the Option which have been registered in the
         holder's name in the share register of the Company upon the due
         exercise of the Option.

5.       REPRESENTATIONS AND COVENANTS OF THE OPTIONEE

         In connection with the grant of the Option hereunder, the Optionee
         represents and warrants to the Company that:

         (a)      The Shares subject to the Option under this Agreement shall be
                  acquired for the Optionee's own account and not with a view
                  to, or present intention of, distribution in violation of the
                  Securities Act of 1933 (the "1933 ACT") or any applicable
                  state securities laws, and the Shares will not be disposed of
                  in contravention of the 1933 Act or any applicable state
                  securities laws.

         (b)      The Optionee is sophisticated in financial matters and has
                  been given the opportunity prior to exercise to evaluate the
                  risks and benefits of the Option and the Shares.

         (c)      The Optionee acknowledges that he is able to bear the economic
                  risk of the exercise of the Option for an indefinite period of
                  time, because the Shares have not been registered under the
                  1933 Act and, therefore, cannot be resold unless subsequently
                  registered under the 1933 Act or an exemption from such
                  registration is available.

         (d)      The Optionee has had an opportunity to ask questions and
                  receive answers concerning the terms and conditions of the
                  grant of the Option and has had full access to such
                  information concerning the Company as he has requested.

         (e)      The Optionee has the full right, power and authority to
                  execute and deliver this Agreement and to perform his
                  obligations hereunder. This Agreement constitutes the valid
                  and legally binding obligations of the Optionee enforceable
                  against him in accordance with its terms, except as the same
                  may be limited by applicable bankruptcy, insolvency,
                  reorganization, moratorium or other laws relating to or
                  affecting the enforcement of creditors' rights generally, now
                  or hereafter in effect and subject to the application of
                  equitable principles and the availability of equitable
                  remedies.

         (f)      The Optionee is not a party to, subject to or bound by any
                  agreement or any judgment, order, writ, prohibition,
                  injunction or decree of any court or other governmental body
                  which would prevent the execution or delivery of this
                  Agreement by him or the consummation of the transactions
                  contemplated hereby.

                                       3
<PAGE>

         (g)      The Optionee understands that neither the issuance of the
                  Option nor any provision contained herein shall entitle the
                  Optionee to remain in the service of the Company or affect the
                  Company's right to terminate the Optionee's employment at any
                  time for any or no reason.

6.       REGISTRATION

         The Optionee understands that the Shares are not currently being
         registered under the 1933 Act by reason of their contemplated issuance
         in a transaction exempt from the registration and prospectus delivery
         requirements of the 1933 Act pursuant to Section 4(2) thereof. The
         Optionee further agrees that he will not sell or otherwise dispose of
         the Shares unless such sale or other disposition has been registered or
         is exempt from registration under the 1933 Act and has been registered
         or qualified or is exempt from registration or qualification under
         applicable securities laws of any state. The Optionee understands that
         a restrictive legend consistent with the foregoing, and as set forth in
         Paragraph 8, will be placed on the certificates evidencing the Shares,
         and related stop transfer instructions will be noted in the stock
         transfer records of the Company and/or its stock transfer agent for the
         Shares.

7.       WITHHOLDING

         The Company shall have the power and right to deduct or withhold, or
         require the Optionee to remit to the Company, an amount sufficient to
         satisfy federal, state, and local taxes required by law to be withheld
         with respect to any grant made under or as a result of this Agreement.
         In the alternative, upon any taxable event hereunder, the Optionee may
         elect, subject to Company approval, to satisfy the withholding
         requirement in whole or in part, by having the Company withhold Shares
         that would otherwise be transferred to the Optionee having a fair
         market value, on the date the tax is to be determined, equal to the
         minimum marginal tax that could be imposed on the transaction. All
         elections shall be made in writing and signed by the Optionee.

8.       LEGEND

         The Optionee shall be bound by the provisions of the following legend
         (or similar legend) which shall be endorsed upon the certificate(s)
         evidencing the Shares issued pursuant to the grant of the Option
         hereunder.

                  "The shares of stock represented by this certificate have been
                  acquired for investment and they may not be sold or otherwise
                  transferred by any person in the absence of an effective
                  registration statement for the shares under the 1933 Act or an
                  opinion of counsel satisfactory to the Company that an
                  exemption is then available."

                  "The shares of stock represented by this certificate are
                  subject to the terms and conditions of a certain Stockholders'
                  Agreement dated as of June 13, 2003, among the Company and
                  certain of its stockholders, and the terms of the Management
                  Agreement dated as of June 13, 2003, between the

                                       4
<PAGE>

                  Company and the Optionee. Copies of the Agreements are on file
                  in the office of the Secretary of the Company. The Agreements
                  provide, among other things, for restrictions upon the
                  holder's right to transfer the shares represented hereby, and
                  for certain prior rights to purchase and certain obligations
                  to sell the shares of stock evidenced by this certificate at a
                  designated purchase price determined in accordance with
                  certain procedures. Any attempted transfer of these shares
                  other than in compliance with the Agreements shall be void and
                  of no effect. By accepting the shares of stock evidenced by
                  this certificate, any permitted transferee agrees to be bound
                  by all of the terms and conditions of said Agreements."

9.       ADJUSTMENTS UPON CHANGES IN CAPITALIZATION.

         If the outstanding Shares of the Company are changed into or exchanged
         for a different number or kind of shares or other securities of the
         Company or of another corporation by reason of any reorganization,
         merger or consolidation, or if a change is made to the stock of the
         Company by reason of any recapitalization, reclassification, change in
         par value, stock split, combination of shares or dividends payable in
         capital stock, or the like, the Company shall make adjustments to the
         Shares granted to, or available for, the Optionee as it may determine
         to be appropriate under the circumstances.

10.      NON-ASSIGNABILITY

         This Option shall not be transferable by the Optionee and shall be
         exercisable only by the Optionee, except as this Agreement may
         otherwise provide.
