(a) Company Units.

(i) Each of the Company’s Class A units (“Class A Units”), Class B units (“Class B Units”) and Class C units (“Class C Units” and, together with the Class A Units and Class B Units, “Units”) issued and outstanding immediately prior to the Effective Time, other than any Units to be canceled pursuant to Section 1.6(b), will be canceled and extinguished and automatically converted (subject to Section 1.6(d)) into the right to receive, respectively, the Class A Per Unit Consideration, the Class B Per Unit Consideration or the Class C Per Unit Consideration (together with the Class A Per Unit Consideration and the Class B Per Unit Consideration, the “Per Unit Consideration”) upon surrender of the certificate representing such Unit in the manner provided in Section 1.7.

(ii) The applicable Per Unit Consideration to be paid in exchange for each Unit as provided in Section 1.6(a)(i) shall include shares of common stock of Parent, par value $0.01 per share (“Parent Common Stock”) and/or cash (“Cash Consideration”) as provided on Exhibit A hereto.

(c) Capital Stock of Merger Sub. Each unit of Merger Sub issued and outstanding immediately prior to the Effective Time shall be converted into one validly issued, fully paid and nonassessable unit of the Surviving Company.

(d) Fractional Shares. No fraction of a share of Parent Common Stock will be issued by virtue of the Merger, but in lieu thereof each holder of Units who would otherwise be entitled to a fraction of a share of Parent Common Stock (after aggregating all fractional shares of Parent Common Stock that otherwise would be received by such holder) shall, upon surrender of such holder’s Units in accordance with Section 1.7(c), receive from Parent an amount of cash (rounded to the nearest whole cent), without interest, less the amount of any withholding taxes as contemplated by Section 1.7(f), which are required to be withheld with respect thereto, equal to the product of: (i) such fraction, multiplied by (ii) the average closing price of one share of Parent Common Stock for the ten (10) most recent trading days that Parent Common Stock has traded ending on the trading day one day prior to the Effective Time, as reported on The Nasdaq Stock Market, Inc.

1.7 Exchange Procedures.

(a) Exchange Agent. Parent hereby designates ▇▇▇▇▇ Fargo or such other party as Parent and the Company shall mutually agree upon to act as the exchange agent (the “Exchange Agent”) in the Merger.

(b) Parent to Provide Cash and/or Common Stock. Prior to the Effective Time (and in any event not less than two (2) days prior to the Closing), Parent shall enter into an agreement with the Exchange Agent, reasonably satisfactory to the Company, which shall provide that Parent shall make available to the Exchange Agent for exchange in accordance with this Article I, the shares of Parent Common Stock issuable and/or cash payable in exchange for outstanding Units pursuant to Section 1.6(a). In addition, Parent shall make available as necessary from time to time after the Effective Time as needed, cash in an amount sufficient for payment in lieu of fractional shares pursuant to Section 1.6(d) and any dividends or distributions which holders of Units may be entitled pursuant to Section 1.7(d). Any cash and/or Parent Common Stock deposited with the Exchange Agent shall hereinafter be referred to as the “Exchange Fund.”

(c) Exchange Procedures. Promptly after the Effective Time but in any event within two (2) business days, Parent shall cause the Exchange Agent to mail to each holder of record (as of the Effective Time) of a Unit or Units that were converted into the right to receive the applicable Per Unit Consideration pursuant to Section 1.6(a), cash in lieu of any fractional shares pursuant to Section 1.6(d) and any dividends or other distributions pursuant to Section 1.7(d): (i) a letter of transmittal (which shall specify that surrender of Units shall be effected only upon delivery of the letter of transmittal to the Exchange Agent and shall be in such form and have such other provisions as Parent may reasonably specify) (the “Letter of Transmittal”) and (ii) instructions for use in effecting the surrender of the Units in exchange for (1) the applicable Per Unit Consideration, (2) cash in lieu of any fractional shares pursuant to Section 1.6(d) and (3) any dividends or other distributions pursuant to Section 1.7(d). Upon delivery of such Letter of Transmittal to the Exchange Agent or to such other agent or agents as may be appointed by Parent, duly completed and validly executed in accordance with the instructions thereto and such other documents as may reasonably be required by the Exchange Agent, the holder of such Units surrendered by such Letter of Transmittal shall be entitled to receive in exchange for each such Unit the applicable Per Unit Consideration (after taking into account all Units surrendered by such holder) to which such holder is entitled pursuant to Section 1.6(a), payment in lieu of fractional shares which such holder has the right to receive pursuant to Section 1.6(d) and any dividends or distributions payable pursuant to Section 1.7(d), and the Units so surrendered shall forthwith be canceled. Any shares of Parent Common Stock issued in exchange for Units shall be in uncertificated book entry form unless a physical certificate is requested or is otherwise required by applicable law or regulation. Until so surrendered, each Unit will be deemed from and after the Effective Time, for all corporate purposes, to evidence the ownership of the applicable Per Unit Consideration (which shall include Cash Consideration and/or the number of

full shares of Parent Common Stock into which such Units shall have been so converted) and the right to receive an amount in cash in lieu of the issuance of any fractional shares in accordance with Section 1.6(d) and any dividends or distributions payable pursuant to Section 1.7(d).

(d) Distributions With Respect to Unexchanged Units. No dividends or other distributions declared with a record date after the Effective Time with respect to shares of Parent Common Stock with a record date after the Effective Time will be paid to the holder of any Unit with respect to the shares of Parent Common Stock represented thereby until the holder of record of such Unit shall surrender such Unit pursuant to Section 1.7(c). Subject to applicable law, following surrender of any such Unit, there shall be paid to the record holder of the Units evidencing full shares of Parent Common Stock that may be issued in exchange therefore pursuant to Section 1.6(a), without interest, at the time of such surrender, the amount of dividends or other distributions with a record date after the Effective Time theretofore paid with respect to such full shares of Parent Common Stock.

(e) Transfers of Ownership. If shares of Parent Common Stock are to be issued in the name of, and/or Cash Consideration paid to, a person other than the person in whose name the Units surrendered in exchange therefor are registered, it will be a condition of the issuance thereof that (i) the appropriate transfer forms be presented for transferring Units, (ii) such transfer complies with applicable Legal Requirements, the Operating Agreement and the procedures established by the Company for transferring Units as in effect on the date hereof and (iii) the persons requesting such exchange will have paid to Parent or any agent designated by it any transfer or other Taxes required by reason of the issuance of shares of Parent Common Stock in the name of, or payment of Cash Consideration to, any person other than the registered holder of the Units surrendered, or established to the satisfaction of Parent or any agent designated by it that such Tax has been paid or is not payable.

(f) Required Withholding. Each of the Exchange Agent and the Surviving Company shall be entitled to deduct and withhold from any consideration payable or otherwise deliverable pursuant to this Agreement to any holder or former holder of Units such amounts as are required to be deducted or withheld therefrom under the Internal Revenue Code of 1986, as amended (the “Code”) or under any provision of state, local or foreign Tax law or under any other applicable Legal Requirement. To the extent such amounts are so deducted or withheld, the amount of such consideration shall be treated for all purposes under this Agreement as having been paid to the person to whom such consideration would otherwise have been paid.

(g) No Liability. Notwithstanding anything to the contrary in this Section 1.7, none of the Exchange Agent, the Surviving Company or any party hereto shall be liable to a holder of Units for any amount properly paid to a public official pursuant to any applicable abandoned property, escheat or similar law.

(h) Investment of Exchange Fund. The Exchange Agent shall invest any cash included in the Exchange Fund as directed by Parent on a daily basis; provided that no such investment or loss thereon shall affect the amounts payable to Company members pursuant to this Article I. Any interest and other income resulting from such investment shall become a part of the Exchange Fund, and any amounts in excess of the amounts payable to Company members pursuant to this Article I shall promptly be paid to Parent.

(i) Termination of Exchange Fund. Any portion of the Exchange Fund which remains undistributed to the holders of Units twelve (12) months after the Effective Time shall, at the request of the Surviving Company, be delivered to the Parent, and any holders of the Units who have not surrendered such Units in compliance with this Section 1.7 shall after such delivery to the Parent look only to the Parent for the applicable Per Unit Consideration pursuant to Section 1.6(a), cash in lieu of any fractional shares pursuant to Section 1.6(d) and any dividends or other distributions pursuant to Section 1.7(d) with respect to the Units. Any such portion of the Exchange Fund remaining unclaimed by holders of Units immediately prior to such time as such amounts would otherwise escheat to or become property of any Governmental Entity shall, to the extent permitted by law, become the property of Parent free and clear of any claim or interest of any person previously entitled thereto.

1.8 No Further Ownership Rights in Units. All shares of Parent Common Stock issued and/or Cash Consideration paid upon the surrender for exchange of Units in accordance with the terms hereof (including any cash paid in respect thereof pursuant to Section 1.6(d)) shall be deemed to have been issued and/or paid in full satisfaction of all rights pertaining to such Units, and there shall be no further registration of transfers on the records of the Surviving Company of Units which were outstanding immediately prior to the Effective Time.

1.9 Further Action. At and after the Effective Time, the officers and directors of Parent and the officers and managers of the Surviving Company will be authorized to execute and deliver, in the name and on behalf of the Company and Merger Sub, any deeds, bills of sale, assignments or assurances and to take and do, in the name and on behalf of the Company and Merger Sub, any other actions and things to vest, perfect or confirm of record or otherwise in the Surviving Company any and all right, title and interest in, to and under any of the rights, properties or assets acquired or to be acquired by the Surviving Company as a result of, or in connection with, the Merger.
