(ii) Acceleration of TARSAP Options. Notwithstanding the foregoing, if on and after the publication of each written determination by the Board of Directors of the Company (the "Board") or a committee thereof which is authorized to do so that the Company has met at least ninety percent (90%) of its objective for EBITDA (as defined below) (100% of the Company's objective referred to herein as the "Performance Goals") with respect to any fiscal year commencing with the fiscal year ending December 31, 1999 and continuing for each of the four fiscal years thereafter (which Performance Goals are set forth on Annex I attached hereto), then (subject to the other restrictions in the Plan and this Agreement), Optionee shall acquire the vested right to exercise the TARSAP Options to purchase ten percent (10%) of the TARSAP Shares, and for each additional one percent (1%) achievement over ninety percent (90%) of the Performance Goals for any such fiscal year, as so determined, Optionee shall acquire the 2 vested right to exercise the TARSAP Options to purchase an additional one percent (1%) of the TARSAP Shares, but no more than twenty percent (20%) of the TARSAP Shares in respect of each full fiscal year. Additionally, 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 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 Performance Goals"), then subject to the other 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 acquired the vested right to exercise (such additional 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 3 shall determine the Additional Exercise Rights with respect to all TARSAP Options as to which Optionee had not otherwise acquired the vested right to exercise consistent with the method set forth in the second 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 4 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 restrictions in the Plan and this Agreement, the Options may be exercised for all or a part of the Shares with respect to which each Option is exercisable under Section 4.1(a) and (b) above. 4.2 Method of Exercise; Stockholders Agreement.

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. 4.3 Exercise After Termination of Employment; Termination of Options.

Purchase for Investment; Other Representations of Optionee; Legends. 6.1 Investment Intent.

(e) Investment Intent. Optionee acknowledges that: (i) Optionee is acquiring the Option for Optionee's own account and not on behalf of any other person; (ii) Optionee is acquiring the option for investment and not with a view to distribution or with the intent to divide Optionee's participation with others or resell or otherwise distribute the Options or the Shares; (iii) Neither Optionee nor anyone acting on Optionee's behalf has paid or will pay a commission or other remuneration to any person in connection with the acquisition of 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. 11 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.

I understand and agree that: (a) There can be no assurance that the Exercised Shares will be registered under the Securities Act of 1933, as amended (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 my representations and warranties contained herein are essential to any claim of exemption by the Company under the Securities Act and such state laws; (b) If the Exercised Shares are not so registered, the Exercised Shares will be "restricted securities" as that term is defined in Rule 144 promulgated under the Securities Act; PAGE 2A - STOCK EXERCISE FORM (c) I cannot resell or transfer the Exercised 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; (d) Only the Company can register the Exercised Shares under the Securities Act and applicable state securities laws; (e) The Company has not made any representations to me that the Company will register the Exercised Shares under the Securities Act or any applicable state securities laws, or with respect to compliance with any exemption therefrom; (f) I am aware of the conditions for obtaining an exemption for the resale of the Exercised Shares under the Securities Act and any applicable state securities laws; (g) The Company may, from time to time, make stop transfer notations in its transfer records to ensure compliance with the Securities Act, and any applicable state securities laws, and any additional restrictions imposed by state securities administrators; and (h) I understand that stock certificates evidencing the Exercised Shares shall bear restrictive legends as more particularly described in the Option Agreement and the Stockholders Agreement. 5. I acknowledge that: (a) I am acquiring the Exercised Shares for my own account and not on behalf of any other person; (b) I am acquiring the Exercised Shares for investment and not with a view to distribution or with the intent to divide my participation with others or resell or otherwise distribute the Exercised Shares; and (c) Neither I nor anyone acting on my behalf has paid or will pay a commission or other remuneration to any person in connection with the acquisition of the Exercised Shares. PAGE 3A - STOCK EXERCISE FORM 6. I acknowledge and understand that an investment in the Shares involves a high degree of risk and my entire investment could be lost, and that these risks include, but are not limited to, the following: (a) The manufacture and sale of the Company's products is highly competitive, and the Company competes with a number of other companies, some of which may be larger and better capitalized. In response to such competition, the Company may be required to lower selling prices to maintain or increase market share, and such measures could adversely affect the Company's gross margins and operating results. (b) The Company may be a party to administrative actions and lawsuits, including product liability claims involving its products. An adverse final judgment in any such proceeding or related actions could have a material adverse effect on the Company's financial condition. (c) UIC Holdings, L.L.C., owns in excess of 90% of the voting shares of the Company. Accordingly, the UIC Holdings, L.L.C. may elect the Company's directors and amend the Company's certificate of incorporation, effect a merger, sale of assets or other business acquisition or disposition, and otherwise control the outcome of many actions requiring stockholder approval. (d) The Company is highly leveraged and is capitalized with a significant amount of senior and subordinated debt. The rights of the holders of the Common Stock are junior to the rights held by the senior lenders and the holders of subordinated debt of the Company. Any proceeds on a sale of the Company or on liquidation, dissolution or winding up of the Company would first be used to pay outstanding debt incurred by the Company. There is no guarantee that the Company can repay its obligations to those with rights senior to the holders of Common Stock or that any money will be available for distribution to holders of Common Stock. (e) Upon termination of employment, the Company has the right (but not the obligation) to purchase all or a portion of the Exercised Shares. As a result, I could be required to hold the Exercised Shares for a period of time after the termination of my employment with the Company. (f) The financial performance of the Company is largely dependent on the capabilities of its senior management. The retention of the key members of PAGE 4A - STOCK EXERCISE FORM management is critical to the success of the Company. Loss of key personnel could lead to poor execution of operating strategies, lost sales and could adversely impact the Company's operating results. Signature Robert L.
