                     percent (87.5 %) of its Performance Goals for the fiscal
                     year ending December 31, 2003 and at least ninety percent
                     (90%) of its cumulative Performance Goals for the five
                     fiscal years ending December 31, 2003 ("Five Year

                     restrictions in the Plan and this Agreement, (i) Optionee
                     shall acquire the vested right to exercise the TARSAP
                     Options to purchase fifty percent (50%) of the TARSAP
                     Shares as to which Optionee had not otherwise acquired the
                     vested right to exercise, and (ii) for each additional one
                     percent (1%) achievement over ninety percent (90%) of the
                     Five Year Performance Goals, as so determined, Optionee
                     shall acquire the vested right to exercise this TARSAP
                     Option to purchase an additional five percent (5%) of the
                     TARSAP Shares as to which Optionee has not otherwise

                     exercise rights pursuant to clauses (i) and (ii) above are
                     referred to herein as the "Additional Exercise Rights").
                     Such determinations shall be made by the Board or such
                     committee within ten (10) days after receipt of audited
                     financial statements for each fiscal year. The Board's or
                     committee's determination as to whether the Company has
                     met such objectives shall be final and not subject to
                     dispute. In addition, the Board or a committee thereof
                     shall have complete discretion to modify such objectives
                     from time to time for any year or years to reflect
                     business combinations or dispositions, fiscal year
                     changes, purchases or sales of assets or any other
                     circumstances the Board or committee thereof deems
                     relevant. For purposes hereof, "EBITDA" shall mean
                     earnings before interest, taxes, depreciation and
                     amortization, excluding any non-recurring or extraordinary
                     items, as determined in accordance with generally accepted
                     accounting principles, consistently applied.

                                (iii) Acceleration Upon Sale. Notwithstanding
                     any provision to the contrary in this Section 4.1(b), but
                     subject to the other restrictions in the Plan and this
                     Agreement, in the event of a Sale (as defined below) prior
                     to December 31, 2003, the TARSAP Options shall become
                     vested and immediately exercisable to the extent set forth
                     below. On and after publication of a written determination
                     by the Board or a committee thereof which is authorized to
                     do so that the Company has met at least eighty seven and
                     one-half percent (87.5 %) of its Performance Goals for the
                     last twelve (12) full months and at least ninety percent
                     (90%) of its cumulative Performance Goals for the
                     completed fiscal years (if any) and the Interim Period (as
                     defined below) (based on months elapsed), the Board or
                     such committee shall treat the percentage of cumulative
                     Performance Goals achieved through the completed fiscal
                     years (if any) and Interim Period as the percentage of
                     Five Year Performance Goals achieved and on that basis
                     shall determine the Additional Exercise Rights with
                     respect to all 400,000 TARSAP Options as to which Optionee
                     had not otherwise acquired the vested right to exercise
                     consistent with the method set forth in the second


                                      - 3 -




                     sentence of Section 4.1(b)(ii) above. The percentage of
                     Five Year Performance Goals for such period shall be
                     computed by dividing (i) the sum of EBITDA achieved for
                     the completed fiscal years (if any) and the Interim Period
                     by (ii) the annual Performance Goals for the completed
                     fiscal years (if any) and the monthly Performance Goals
                     for the Interim Period. For purposes hereof, the term
                     "Interim Period" shall mean the period beginning on the
                     first day of the then current fiscal year and ending on
                     the last full month of that uncompleted fiscal year.

                     For purposes hereof, the term "Sale" shall mean:

                                (w) the acquisition by any individual, entity
                     or group (within the meaning of Section 13(d)(3) or
                     14(d)(2) of the Exchange Act) (a "Person") of beneficial
                     ownership (within the meaning of Rule 13d-3 promulgated
                     under the Exchange Act) of voting securities of (a) the
                     Company or (b) the surviving entity in any reorganization,
                     merger or consolidation (each an "Acquisition") involving
                     the Company (any such entity referred to herein as the
                     "Corporation") where such Acquisition causes such Person
                     to own more than fifty percent (50%) of the combined
                     voting power of the then outstanding voting securities of
                     the Corporation entitled to vote generally in the election
                     of directors, other than acquisitions by the Thomas H. Lee
                     Company or its affiliates;

                                (x) approval by the shareholders of the Company
                     of a complete liquidation or dissolution of the Company;

                                (y) the acquisition by a third party not
                     affiliated with the Company of all or substantially all of
                     the Company's assets; or

                                (z) individuals who constitute the Board on the
                     date of the Company's initial public sale of equity
                     securities registered under the Securities Act (the
                     "Incumbent Board") cease for any reason to constitute at
                     least a majority of the Board thereafter. Any person
                     becoming a director subsequent to such date whose,
                     election, or nomination for election, is, at any time,
                     approved by a vote of at least a majority of the directors
                     comprising the Incumbent Board shall be considered a
                     member of the Incumbent Board.

                     The accelerated vesting provided in this Section 
4.1(b)(iii) shall take effect immediately prior to but contingent upon the Sale
giving rise to such accelerated vesting. The phrase "immediately prior to the
Sale" shall be understood to mean sufficiently in advance of a Sale to permit
the Optionee to take all steps reasonably necessary to permit the Optionee to
become a shareholder of the Company as of the consummation of such Sale with
respect to the TARSAP Shares subject to the accelerated vesting provided in this
Section 4.1(b)(iii). The Board or committee thereof may in good faith shorten
the Interim Period or make approximations of EBITDA during the Interim Period in
order to comply with the preceding sentence.

                     (c)       Partial Exercise. Subject to the other

                     substantially in the form attached hereto or in such other
                     form as the Company may require. Except as otherwise
                     permitted by Section 6(d) of the Plan, such notice shall be
                     accompanied by payment in full for the Shares to be
                     purchased. Payment of the Exercise Price may be made: (i)
                     in cash, (ii) in shares of Common Stock which either (A)
                     were purchased by Optionee in other than a compensatory
                     transaction, (B) have been held by Optionee free and clear
                     for at least six (6) months prior to the use thereof to pay

                     sufficient to pay a portion of the Exercise Price subject
                     to this clause (iii), or a combination of the methods
                     specified in clauses (i), (ii) and (iii), or in the sole
                     discretion of the Committee, through a cashless exercise
                     procedure. Optionee shall also execute and deliver to the
                     Company a copy of the Company's Stockholders Agreement,
                     dated as of January 20, 1999, in the form in effect at the
                     time of exercise (as amended and modified from time to
                     time, the "Stockholders Agreement"), if Optionee has not
                     previously done so. Upon due exercise of any Option and (if
                     required) execution and delivery of the Stockholders
                     Agreement, subject to the terms and conditions in this
                     Agreement, the Company shall issue in the name of Optionee
                     and deliver to Optionee a certificate for the Shares in
                     respect of which such Option shall have been exercised, but
                     no Shares will be issued until arrangements satisfactory to
                     Company have been made for appropriate income tax
                     withholding, if any, pursuant to Section 12 hereof.

                     Options.

                     (a)       Definitions. For purposes of this Section 4.3,
                               the capitalized terms Good Reason, Cause, and
                               Disability shall have the meanings set forth in
                               the Management Agreement.

                     (b)       Termination Without Good Reason. Upon any
                               termination of employment by Optionee without
                               Good Reason, the Options may, to the extent
                               exercisable and not terminated pursuant to
                               Section 4.3(e), be exercised only within thirty
                               (30) days after the date of such employment
                               termination. This Section 4.3(b) shall not,
                               however, extend the term of the Options beyond


                                      - 5 -




                               that specified in Section 4.3(e). For purposes
                               of this Section 4.3(b), the extent to which the
                               Options are exercisable shall be determined as
                               of the date of termination of employment.

                     (c)       Termination by Virtue of Death or Disability or
                               Without Cause or With Good Reason. Upon any
                               termination of employment of Optionee by virtue
                               of Optionee's death or Disability or upon any
                               termination of employment by Optionee with Good
                               Reason, or by the Company without Cause, the
                               Options may, to the extent exercisable and not
                               terminated pursuant to Section 4.3(e), be
                               exercised only within twelve (12) months after
                               the date of such termination. This Section 4.3
                               (c) shall not extend the term of the Options
                               beyond that specified in Section 4.3(e). For
                               purposes of this Section 4.3(c), the extent to
                               which the Options are exercisable shall be
                               determined as of the date of termination of
                               employment.

                     (d)       Termination for Cause. The Option shall
                               terminate immediately upon termination of the
                               employment of Optionee for Cause.

                     (e)       Other Termination. The Options shall not be
                               exercisable after the earliest of (i) a Sale
                               (provided that Optionee has at least five (5)
                               business days prior to the Sale to exercise the
                               Options or the Options are treated as exercised
                               in connection with such Sale) or (ii) January
                               20, 2009.

                     (f)       Company Repurchase; Extension of Exercise Period.
                               If Optionee properly elects to exercise all or
                               any portion of the Option following a termination
                               of Optionee's employment as described in Section
                               4.3(c) (a "Post-Termination Exercise"), at the
                               written request of Optionee delivered to the
                               Company prior to or simultaneously with the
                               attempted exercise of such Option, the Company
                               shall either:

                                 (i) offer to purchase from Optionee, within
                      fifteen (15) days following its receipt of such request,
                      at a purchase price equal to Fair Market Value, such
                      portion of the Shares obtained by Optionee through the
                      Post-Termination Exercise having an aggregate Fair Market
                      Value equal to the excess of (A) Optionee's aggregate
                      federal, state and local income tax obligations in respect
                      of the Post-Termination Exercise over (B) any amounts
                      related to income tax previously withheld by the Company
                      with respect to such Post-Termination Exercise; or

                                 (ii) extend the period during which Optionee
                      may exercise the Options specified in Optionee's notice
                      until the earlier of (A) such time as the Company elects
                      to comply with Section 4.3(f)(i), above (disregarding the
                      fifteen (15) day period referenced therein), and (B) such
                      time as the Shares to be received by Optionee upon the
                      exercise of the Options specified in Optionee's notice are
                      registered under the Securities Act and freely tradable.


                                      - 6 -





5.         Non-transferability of Options. The Options shall not be transferable
           or assignable except upon Optionee's death by will or the laws of
           descent and distribution and shall be exercisable, during Optionee's
           lifetime, only by Optionee.

6.         Purchase for Investment; Other Representations of Optionee; Legends.

           6.1       Investment Intent. As provided in the Plan, in the event
                     that the offering of Shares with respect to which the
                     Options are being exercised is not registered under the
                     Securities Act, but an exemption is available that requires
                     an investment representation or other representation,
                     Optionee, if electing to purchase Shares, will be required
                     to represent that such Shares are being acquired for
                     investment and not with a view to distribution thereof, and
                     to make such other reasonable and customary representations
                     regarding matters relevant to compliance with applicable
                     securities laws as are deemed necessary by counsel to the
                     Company. Stock certificates evidencing such unregistered
                     Shares that are acquired upon exercise of the Options shall
                     bear restrictive legends in substantially the following
                     form and such other restrictive legends as are required or
                     advisable under the provisions of any applicable laws or
                     are provided for in the Stockholders Agreement or any other
                     agreement to which Optionee is a party:

                               THE SHARES REPRESENTED BY THIS STOCK CERTIFICATE
           HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED
           (THE "SECURITIES ACT"), NOR UNDER ANY STATE SECURITIES LAWS AND SHALL
           NOT BE TRANSFERRED AT ANY TIME IN THE ABSENCE OF (I) AN EFFECTIVE
           REGISTRATION STATEMENT UNDER THE SECURITIES ACT AND APPLICABLE STATE
           SECURITIES LAWS WITH RESPECT TO SUCH SHARES AT SUCH TIME, OR (II) AN
           OPINION OF COUNSEL SATISFACTORY TO THE COMPANY AND ITS COUNSEL, TO
           THE EFFECT THAT SUCH TRANSFER AT SUCH TIME WILL NOT VIOLATE THE
           SECURITIES ACT OR ANY APPLICABLE STATE SECURITIES LAWS.

           6.2       Other Representations. Optionee hereby represents and
                     warrants to the Company as follows:

                     (a)        Access to Information. Because of Optionee's
                                business relationship with the Company and with
                                the management of the Company, Optionee has had
                                access to all material and relevant information
                                concerning the Company, thereby enabling
                                Optionee to make an informed investment
                                decision with respect to his investment in the
                                Company, and all pertinent data and information
                                requested by Optionee from the Company or its
                                representatives concerning the business and
                                financial condition of the Company and the
                                terms and conditions of this Agreement have
                                been furnished. Optionee acknowledges that
                                Optionee has had the opportunity to ask
                                questions of and receive answers from and to
                                obtain additional information from the Company


                                      - 7 -




                                and its representatives concerning the present
                                and proposed business and financial condition
                                of the Company.

                     (b)        Financial Sophistication. Optionee has such
                                knowledge and experience in financial and
                                business matters that Optionee is capable of
                                evaluating the merits and risks of investing in
                                the Shares.

                     (c)        Understanding the Investment Risks. Optionee
                                understands that:

                                (i)        An investment in the Shares
                                           represents a highly speculative
                                           investment, and there can be no
                                           assurance as to the success of the
                                           Company in its business; and

                                (ii)       There is at present no market for
                                           the Shares and there can be no
                                           assurance that a market will develop
                                           in the future.

                     (d)        Understanding of the Nature of the Shares.
                                Optionee understands and agrees that:

                                (i)        There can be no assurance that the
                                           Shares will be registered under the
                                           Securities Act or any state
                                           securities laws and if they are not
                                           so registered, they will only be
                                           issued and sold in reliance upon
                                           certain exemptions contained in the
                                           Securities Act and applicable state
                                           securities laws, and the
                                           representations and warranties of
                                           Optionee contained herein, which
                                           will have to be renewed as to the
                                           Shares at the times of exercise of
                                           the Options, are essential to any
                                           claim of exemption by the Company
                                           under the Securities Act and such
                                           state laws;

                                (ii)       If the Shares are not so registered,
                                           the Shares will be "restricted
                                           securities" as that term is defined
                                           in Rule 144 promulgated under the
                                           Securities Act;

                                (iii)      The Option cannot be exercised and
                                           the Shares will not be sold to
                                           Optionee and Optionee cannot resell
                                           or transfer the Shares without
                                           registration under the Securities
                                           Act and applicable state securities
                                           laws unless the Company receives an
                                           opinion of counsel acceptable to it
                                           (as to both counsel and the opinion)
                                           that such registration is not
                                           necessary, the cost of such opinion
                                           to be borne by the Company;

                                (iv)       Only the Company can register the
                                           Shares under the Securities Act and
                                           applicable state securities laws;


                                      - 8 -




                                (v)        The Company has not made any
                                           representations to Optionee that the

                                (vi)       Optionee is aware of the conditions
                                           for Optionee's obtaining an

                                           and any applicable state securities
                                           laws, and any additional
                                           restrictions imposed by state
                                           securities administrators.

                                (ii)       Optionee is acquiring the option for
                                           investment and not with a view to

                                (iii)      Neither Optionee nor anyone acting
                                           on Optionee's behalf has paid or
                                           will pay a commission or other
                                           remuneration to any person in

                                           the Options or the Shares; and

                                (iv)       At the time of exercise of any
                                           Option, Optionee will have to make
                                           all the representations and
                                           warranties contained in this Section
                                           6 with respect to the Shares to be
                                           issued and other representations
                                           concerning investment intent as a
                                           condition of the issuance of the
                                           Shares by the Company.

7.         Restriction on Issuance of Shares. The Company shall not be obligated
           to sell or issue any Shares pursuant to this Agreement if such
           issuance would result in the violation of any laws, including the
           Securities Act or any applicable state securities laws. The Company
           agrees to use its reasonable best efforts to qualify for available
           exemptions under the Securities Act or any applicable state
           securities laws which will enable it to issue Shares hereunder in
           compliance with applicable law.

8.         Rights as a Shareholder. Optionee shall have no rights as a
           shareholder with respect to any Shares covered by the Options until
           the date of exercise and payment of the Exercise Price in accordance
           with the terms of this Agreement. Subject to Section 3 hereof, no


                                      - 9 -





           adjustment shall be made for dividends or other rights for which the
           record date is prior to the date such stock certificate is issued.

9.         No Employment Rights. This Agreement shall not confer upon Optionee
           any right with respect to the continuance as an employee of the
           Company or any Subsidiary, nor shall it interfere in any way with the
           right of the Company or any Subsidiary to terminate such employment
           at any time.

10.        Governing Law. All issues and questions concerning the construction,
           validity, enforcement and interpretation of this Agreement shall be
           governed by, and construed in accordance with, the laws of the State
           of Delaware, without giving effect to any choice of law or conflict
           of law rules or provisions (whether of the State of Delaware or any
           other jurisdiction) that would cause the application of the laws of
           any jurisdiction other than the State of Delaware.

           shall be in writing, and shall be deemed to have been duly given on

12.        Withholdings. Except to the extent prohibited by applicable law,
           Optionee may satisfy any required withholding obligation upon the
           exercise of an Option hereunder by either of the following methods,
           or by a combination of such methods: (a) tendering a cash payment or
           (b) delivering to the Company previously acquired Shares, or having
           the Company withhold Shares otherwise deliverable upon the exercise
           of an Option, in either case having an aggregate Fair Market Value,
           determined as of the date the withholding obligation arises, less
           than or equal to the amount of the total withholding obligation.

13.        Pro Rata Exercise. The Shares of Common Stock covered by this Option
           shall only be exercised, if at all, ratably among the Class A Shares
           and Class B Shares, based on the 


                                     - 10 -




           aggregate number of Class A Shares and Class B Shares subject to the
           Options granted hereunder.

14.        Registration of Shares. At any time after UIC Holdings, L.L.C.,
           together with its affiliates, holds less than 25% of the Common Stock
           held by such entities as of the date hereof, Optionee shall have the
           right to cause the Company to register all of the Shares on a Form
           S-8, along with a Form S-3 reoffer prospectus, under the Securities
           Act of 1933, as amended from time to time, or any successor form
           thereto, and the Company shall use its reasonable best efforts to
           comply with such request in a timely manner.
