(c) Other Agreements. Executive shall have executed and delivered each of (i) the LLC Agreement, (ii) the Members Agreement and (iii) the Registration Rights Agreement, and each such agreement shall be in full force and effect.

Section 3. Representations and Warranties of Executive. In connection with the purchase and sale of the Executive Units hereunder, Executive represents and warrants to the Company as of the date hereof as follows:

(a) The Executive Units to be acquired by Executive pursuant to this Agreement will be acquired for Executive’s own account and not with a view to, or intention of, distribution thereof in violation of the Securities Act, any applicable state securities laws or the terms of this Agreement, the LLC Agreement or the Members Agreement, and Executive’s interests in such units will not be disposed of in contravention of any such laws or agreements.

(b) Executive is able to bear the economic risk of the investment in the Executive Units for an indefinite period of time because the Executive Units are subject to the transfer restrictions contained herein and in the LLC Agreement and the Members Agreement and have not been registered under the Securities Act.

(c) Executive has had an opportunity to ask questions and receive answers concerning the terms and conditions of the offering of the Executive Units and has had full access to such other information concerning the Company as Executive has requested. Executive has reviewed, or has had an opportunity to review, copies of the following documents: (i) the LLC Agreement, (ii) the Members Agreement and (iii) the Registration Rights Agreement.

(d) Each of this Agreement and the Related Agreements constitutes the legal, valid and binding obligation of Executive, enforceable against Executive in accordance with its terms, except as enforceability may be limited by bankruptcy, insolvency, reorganization, moratorium or other laws affecting creditors’ rights generally and limitations on the availability of equitable remedies, and the execution, delivery, and performance of this Agreement or any of the Related Agreements by Executive does not and will not conflict with, violate, or cause a breach of any agreement, contract, or instrument to which Executive is a party or any judgment, order, or decree to which Executive is subject.

(e) Executive is an “Accredited Investor” as defined in Regulation D under the Securities Act and Executive considers himself to be an experienced and sophisticated investor and to have such knowledge and experience in financial and business matters as are necessary to evaluate the merits and risks of an investment in the Executive Units. Executive acknowledges and understands that an investment in the Executive Units involves substantial risks and Executive is able to bear the economic risks of an investment in the Executive Units pursuant to the terms hereof, including the complete loss of Executive’s investment in the Executive Units.

(f) As a condition precedent to each issuance of the Executive Units pursuant to this Agreement, Executive shall execute and deliver to the Company and the Internal Revenue Service (the “IRS”) a timely, valid election under Section 83(b) of the Code (the “83(b) Election”). Executive understands that under Section 83(b) of the Code, regulations promulgated thereunder, and certain IRS administrative announcements (including Revenue Procedure 2001-43), in the absence of an effective election under Section 83(b) of the Code, the excess of the fair market value of the Executive Units on the date on which any forfeiture restrictions applicable to such Executive Units lapse over the price paid for such units (which, for the Executive Units

issued hereunder, is $0.00) is reportable as ordinary income at that time. For this purpose, the term “forfeiture restrictions” means the restrictions on transferability, the repurchase provisions and the vesting conditions imposed under Section 5 and Section 6 hereof. Executive understands that (i) in making the 83(b) Election, Executive may be taxed at the time the Executive Units are acquired hereunder to the extent the fair market value of the Executive Units exceeds the purchase price for such units and (ii) in order to be effective, the 83(b) Election must be filed with the IRS within thirty (30) days after the date upon which the Executive Units were purchased hereunder. Executive hereby acknowledges that: (x) the foregoing description of the tax consequences of the 83(b) Election is not intended to be complete and, among other things, does not describe state, local or foreign income and other tax consequences; (y) none of the Company, ABRY or any of the Company’s or ABRY’s respective affiliates, officers, employees, agents or representatives (each, a “Related Person”) has provided or is providing Executive with tax advice regarding the 83(b) Election or any other matter, and the Company and ABRY have urged Executive to consult Executive’s own tax advisor with respect to income taxation consequences of purchasing, holding and disposing of the Executive Units; and (z) none of the Company, ABRY or any Related Person has advised Executive to rely on any determination by it or its representatives as to the fair market value specified in the 83(b) Election and will have no liability to Executive if the actual fair market value of the Executive Units on the date hereof exceeds the amount specified in the 83(b) Election.

(g) None of the Company, ABRY or any Related Person has made any representation or warranty, express or implied, as to the future performance of the Company or the present or future value of the Executive Units to be purchased by Executive. Executive further acknowledges that: (i) all forecasts, projections or illustrations of amounts that might be realized as a result of Executive’s purchase of the Executive Units that the Company, ABRY or a Related Person shared with Executive (collectively, “Illustrations”), if any, were purely hypothetical; (ii) none of the Company, ABRY or any Related Person intended for Executive to rely upon such Illustrations in the process of making an investment decision, and (iii) Executive has not relied on such Illustrations in the process of making an investment decision. _____ [initial].

(c) Authorization; No Breach; Consents. The execution, delivery and performance by the Company or its officers of this Agreement and the Related Agreements and

the offer, sale and issuance of the Executive Units hereunder have been duly authorized by the Company. Each of this Agreement and the Related Agreements constitutes a valid and binding obligation of the Company, enforceable in accordance with its terms, except as enforceability may be limited by bankruptcy, insolvency, reorganization, moratorium or other laws affecting creditors’ rights generally and limitations on the availability of equitable remedies.

Section 5. Vesting. The Executive Units acquired by Executive pursuant to this Agreement will “vest” as provided in this Section 5. The provisions of this Section 5 will be in all respects subject to the provisions of Section 6 below.

(a) General. Subject to Sections 5(b) and 5(c) below, as of any date, the number of Executive Units of each series of Class D Common Units issued to Executive pursuant to Section 1 above that will be “Vested Units” will equal the total number of Executive Units in such series multiplied by the percentage for such date set forth on Schedule 1 attached hereto; provided, that all of the Executive Units will immediately vest and become Vested Units upon a Sale of the Company if Executive is an employee of the Company or any Subsidiary of the Company at the time such Sale of the Company is consummated. As of any date, the term “Unvested Units” means the Executive Units that are not Vested Units.

(b) Accelerated Vesting Upon Executive’s Death. Notwithstanding anything to the contrary in Section 5(a) above, upon Executive’s death, if at the time of such death Executive is employed by the Company and such death does not occur on an Anniversary Date, the number of Executive Units of each Series of Class D Common Units issued to Executive pursuant to Section 1 above that will be Vested Units will equal the sum of (i) the number of Executive Units in such series that are Vested Units as of such date pursuant to Section 5(a) above plus (ii) a pro rata portion (determined based upon the number of days that have elapsed as of the date of Executive’s death since the immediately prior Anniversary Date (or, if Executive’s death occurs prior to the first Anniversary Date, the number of days that have elapsed since the date hereof)) of the Executive Units in such series, in addition to those already vested as of the date of Executive’s death, that would have vested and become Vested Units on the next Anniversary Date had Executive remained continuously employed by the Company through such Anniversary Date. For purposes of this Section 5(b), “Anniversary Date” means each of the first five annual anniversaries of the date hereof.

(c) Termination of Vesting. Notwithstanding Sections 5(a) and 5(b) above, if Executive ceases to be employed by the Company or any of its Subsidiaries prior to a Sale of the Company, then vesting will cease, with the effect that from and after the date of such cessation the percentage of the Executive Units of each series of Class D Common Units issued to Executive pursuant to Section 1 above that will be Vested Units will be the percentage of such units that constitute Vested Units as determined pursuant to Section 5(a) above and, if applicable, Section 5(b) above as of the date such employment ceased, whether or not a Sale of the Company occurs thereafter.

(d) Transfer. Executive may transfer Vested Units or Unvested Units only in accordance with the Members Agreement, the LLC Agreement and Section 6 below. Furthermore, Executive may not agree to offer or sell, grant any call option with respect to, pledge, hypothecate, borrow against, grant a lien, security interest or other encumbrance in or on,

dispose of or enter into any swap or derivative transaction with respect to any Vested Unit or Unvested Unit or any interest therein without the prior written consent of the Board. Any attempted or purported transfer, sale, grant, pledge, hypothecation or other agreement in violation of this Agreement shall be void ab initio.

(e) Rights as a Member. Executive shall be the record owner of the Executive Units until or unless such Executive Units are forfeited or repurchased pursuant to Section 6 below or transferred in accordance with the terms of the LLC Agreement and the Members Agreement, and as record owner shall be entitled to all rights granted to owners of Class D Units.

(a) Repurchase Option. If Executive ceases to be employed by the Company or any of its Subsidiaries (the “Termination” of Executive), the Executive Units shall be subject to repurchase by the Company (or its nominee) pursuant to the terms and conditions set forth in this Section 6.

(b) Purchase Price. The purchase price for each Unvested Unit shall be $0.01, and the purchase price for each Vested Unit shall be the Fair Market Value (as defined below) for such unit as of the date of the Termination; provided, that if the Termination results from Executive’s resignation or the Company’s or a Subsidiary’s termination of Executive’s employment for Cause, then the purchase price for each Vested Unit shall be $0.01. The “Fair Market Value” of any Vested Unit on any date means the amount determined by the Board in its good faith judgment as the amount that would be received by the holder of such Vested Unit if all of the equity securities of the Company were sold to a buyer in a single transaction and the proceeds from such transaction were allocated to the holders of equity securities of the Company as if the proceeds were distributed in a liquidation of the Company pursuant to the LLC Agreement; provided, however, that if the holder of such Vested Units disputes the Board’s determination of Fair Market Value (the “Disputing Party”) and the Disputing Party and the Board are unable to reach agreement as to the Fair Market Value within a reasonable period of time, the Company and the Disputing Party shall seek an independent appraisal of such Fair Market Value by an independent appraiser experienced in valuing securities such as the Executive Units and mutually agreeable to the Company and the Disputing Party, and the determination of such appraiser shall be final and binding upon the Company and the Disputing Party. The cost and expense of such appraisal shall be paid 50% by the Company and 50% by the Disputing Party.

(c) Repurchase Procedures. The Company (or its nominee) may elect to purchase all or any portion of the Vested Units and/or the Unvested Units by delivering written notice (the “Repurchase Notice”) to the holder or holders of such Executive Units within 90 days after the Termination of Executive (the “Repurchase Period”). The Repurchase Notice shall set forth the number of Vested Units and/or Unvested Units to be acquired from each holder of Executive Units, the aggregate consideration to be paid for such Vested Units and/or Unvested Units and the time and place for the closing of the transaction. At any time prior to the closing of such transaction, the Company may rescind the Repurchase Notice for any reason (including for no reason at all) without liability to the holders of Executive Units. The Executive Units to be repurchased by the Company shall first be satisfied to the extent possible from the Executive

Units held by Executive at the time of delivery of the Repurchase Notice. If the number of Vested Units and/or Unvested Units then held by Executive is less than the total number of Vested Units and/or Unvested Units that the Company has elected to purchase, the Company shall purchase the remaining Executive Units to be purchased from the other holder(s) of Executive Units under this Agreement, pro rata according to the number of (i) if Vested Units are to be repurchased, the Vested Units and (ii) if Unvested Units are to be repurchased, the Unvested Units, in either case, held by such other holder(s) at the time of delivery of such Repurchase Notice (determined as close as practicable to the nearest whole units).

(d) Closing of Repurchase. The closing of the purchase of such Executive Units pursuant to Sections 6(c) above shall take place on the date designated by the Company in the Repurchase Notice. The Company (or its nominee) shall pay for such Executive Units to be purchased by delivery of a check or wire transfer of immediately available funds. In connection with the purchase of Executive Units hereunder, the Company shall be entitled to receive customary representations and warranties from the sellers regarding such sale of units (including representations and warranties regarding good title to such units, free and clear of any liens or encumbrances).
