ARTICLE III

CONVERSION OF SHARES; EXCHANGE OF CERTIFICATES

Section  3.1      Effect on Capital Stock . At the Effective Time, by virtue of the Merger and without any further action on the part of Rockets or the holders of any securities of Rockets:

(a)     Conversion of Rockets Common Stock . Subject to Section 3.1(b) and Section 3.1(c) , each share of common stock of Rockets, par value $0.01 per share (“ Rockets Common Stock ”), issued and outstanding immediately prior to the Effective Time, excluding any Cancelled Shares (each such share, excluding any Cancelled Shares, an “ Eligible Share ”), shall, at the Effective Time, automatically be converted into the right to receive 0.652 (the “ Exchange Ratio ”) validly issued, fully paid and nonassessable shares of Mavericks Common Stock (the “ Merger Consideration ”). As a result of the Merger and without any action on the part of the holder of any securities of Rockets, (i) all of the Eligible Shares converted into the right to receive the Merger Consideration pursuant to this Article III shall cease to be outstanding, shall be cancelled and shall cease to exist, in each case, as of the Effective Time, and (b) the holders of Eligible Shares not represented by Certificates (“ Book-Entry Shares ”) and the holders of Eligible Shares represented by certificates (each, a “ Certificate ”) shall cease to have any rights with respect thereto, except (i) the right to receive the Merger Consideration to be paid in consideration therefor upon surrender of such Book-Entry Shares or Certificates and (ii) the right, if any, to receive pursuant to Section 3.1(c) cash in lieu of fractional shares into which such Eligible Shares have been converted pursuant to this Section 3.1(a) and any dividends or other distributions pursuant to Section 3.2(c) .

(b)     Cancellation of Shares . Each share of Rockets Common Stock issued and outstanding immediately prior to the Effective Time that is (i) owned by Mavericks or any wholly owned Subsidiary of Mavericks, (ii) held in treasury by Rockets or (iii) owned by any wholly owned Subsidiary of Rockets (all such shares of Rockets Common Stock, other than shares of Rockets Common Stock held on behalf of Third Parties, the “ Cancelled Shares ”) shall, by virtue of the Merger and without any further action on the part of any Person, be cancelled and shall cease to exist, and no consideration shall be delivered in exchange for such cancellation.

(c)     Fractional Shares .

(i)    No fractional shares of Mavericks Common Stock shall be issued in the Merger, but in lieu thereof each former holder of Eligible Shares otherwise entitled to a fractional share of Mavericks Common Stock (after aggregating all fractional shares of Mavericks Common Stock issuable to such former holder) will be entitled to receive, from the Exchange Agent in accordance with the provisions of this Section 3.1(c) , a cash payment in lieu of such fractional share of Mavericks Common Stock representing such former holder’s proportionate interest, if any, in the proceeds from the sale by the Exchange Agent (reduced by any fees of the Exchange Agent attributable to such sale) in one or more transactions of shares of

19

Mavericks Common Stock equal to the excess of (A) the aggregate number of shares of Mavericks Common Stock to be delivered to the Exchange Agent by Mavericks pursuant to Section 3.2(a) over (B) the aggregate number of whole shares of Mavericks Common Stock to be distributed to the former holders of Eligible Shares pursuant to Section 3.2(b) (such excess, the “ Excess Shares ”). The Parties acknowledge that payment of the cash consideration in lieu of issuing fractional shares of Mavericks Common Stock was not separately bargained-for consideration but merely represents a mechanical rounding off for purposes of avoiding the expense and inconvenience to Mavericks that would otherwise be caused by the issuance of fractional shares of Mavericks Common Stock. As soon as reasonably practicable after the Effective Time, the Exchange Agent, as agent for the former holders of Eligible Shares that would otherwise receive fractional shares of Mavericks Common Stock, shall sell the Excess Shares at the then-prevailing prices on the New York Stock Exchange (the “ NYSE ”) in the manner provided in Section 3.1(c)(ii) .

(ii)    The sale of the Excess Shares by the Exchange Agent, as agent for the former holders of Eligible Shares that would otherwise receive fractional shares of Mavericks Common Stock, shall be executed on the NYSE through one or more member firms of the NYSE and shall be executed in round lots to the extent practicable. Until the proceeds of such sale or sales have been distributed to the former holders of Eligible Shares, the Exchange Agent shall hold such proceeds in trust for the former holders of Eligible Shares that would otherwise receive fractional shares of Mavericks Common Stock (the “ Common Shares Trust ”). The Exchange Agent shall determine the portion of the Common Shares Trust to which each former holder of Eligible Shares shall be entitled, if any, by multiplying (A) the amount of the aggregate proceeds comprising the Common Shares Trust by (B) a fraction, (1) the numerator of which is the amount of the fractional share interest to which such former holder of Eligible Shares would otherwise be entitled and (2) the denominator of which is the aggregate amount of fractional share interests to which all former holders of Eligible Shares would otherwise be entitled.

(iii)    As soon as practicable after the determination of the amount of cash, if any, to be paid to holders of Eligible Shares in lieu of any fractional shares of Mavericks Common Stock, the Exchange Agent shall make available such amounts to such holders of shares of Mavericks Common Stock without interest, subject to and in accordance with Section 3.2 .

(d)     Adjustments to the Exchange Ratio . If at any time during the period between the date hereof and the Effective Time, any change in the outstanding shares of capital stock of Mavericks or Rockets (or any other securities convertible therefor or exchangeable thereto) occurs as a result of any reclassification, stock split (including a reverse stock split) or combination, exchange or readjustment of shares, or any stock dividend or stock distribution with a record date during such period (in each case, other than a conversion pursuant to the Certificate of Designation (as in effect on the date of this Agreement) of the Rockets 5.375% Preferred Stock), the Exchange Ratio, the Merger Consideration and any other similarly dependent items shall be equitably adjusted to provide to Mavericks and the holders of Eligible Shares the same economic effect as contemplated by this Agreement prior to such action, and thereafter, all references in this Agreement to the Exchange Ratio shall be references to the Exchange Ratio as so adjusted; provided , however , that nothing in this Section 3.1(d) shall be deemed to permit or authorize any Party to effect any such change that it is not otherwise

20

authorized or permitted to undertake pursuant to this Agreement. For the avoidance of doubt, the issuance or distribution of Escrow Shares shall not give rise to any adjustment under the terms of this Section 3.1(d) .

Section 3.2     Exchange of Shares .

(a)     Exchange Agent . Prior to the Effective Time, Rockets shall appoint an exchange agent reasonably acceptable to Mavericks (the “ Exchange Agent ”) for the purpose of exchanging Eligible Shares for the Merger Consideration. Prior to the Effective Time, Mavericks shall deposit, or shall cause to be deposited, with the Exchange Agent, in trust for the benefit of holders of the Eligible Shares, a number of shares of Mavericks Common Stock in book-entry form equal to the number of shares of Mavericks Common Stock issuable pursuant to Section 3.1(a) . Following the Effective Time, Mavericks agrees to make available to the Exchange Agent, from time to time as needed, cash sufficient to pay any dividends and other distributions pursuant to Section 3.2(c) . All such book-entries representing shares of Mavericks Common Stock (including the amount of any dividends or other distributions payable with respect thereto pursuant to Section 3.2(c) and cash in lieu of any fractional shares of Mavericks Common Stock to be paid pursuant to Section 3.1(c) ) are hereinafter referred to as the “ Exchange Fund ”.

(b)     Exchange Procedures . As soon as reasonably practicable after the Effective Time and in any event not later than the fifth Business Day following the Closing Date, Mavericks shall cause the Exchange Agent to transmit (or mail in the case of Eligible Shares represented by a Certificate) to each former holder of Eligible Shares, (i) a letter of transmittal (which shall specify that delivery shall be effected, and that risk of loss and title to the Eligible Shares shall pass, only upon delivery of the Eligible Shares to the Exchange Agent and which shall be in form and substance reasonably satisfactory to Rockets and Mavericks) and (ii) instructions for use in effecting the surrender of the Eligible Shares in exchange for (A) whole shares of Mavericks Common Stock, (B) cash in lieu of any fractional shares of Mavericks Common Stock pursuant to Section 3.1(c) and (C) any dividends or other distributions payable pursuant to Section 3.2(c) . Notwithstanding anything to the contrary in this Agreement, no former record holder of a Book-Entry Share shall be required to deliver a Certificate or an executed letter of transmittal to the Exchange Agent to receive the Merger Consideration in respect of such Book-Entry Shares. In lieu thereof, such former record holder shall upon receipt by the Exchange Agent of an “agent’s message” in customary form (or such other evidence, if any, as the Exchange Agent may reasonably request), be entitled to receive, and Mavericks shall cause the Exchange Agent to deliver as promptly as reasonably practicable after the Effective Time, the Merger Consideration in respect of each Book-Entry Share of such former holder, and such Book-Entry Shares shall forthwith be cancelled. Upon surrender of Eligible Shares for cancellation and exchange to the Exchange Agent, together with such letter of transmittal, 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 former holder of such Eligible Shares shall be entitled to receive in exchange therefor that number of whole shares of Mavericks Common Stock (after taking into account all Eligible Shares surrendered by such former holder) to which such former holder is entitled pursuant to Section 3.1 (which shall be in uncertificated, book-entry form unless a physical certificate is requested), payment by check in lieu of fractional shares of Mavericks Common Stock which such former holder is entitled to receive pursuant to Section 3.1(c) and any dividends or distributions payable pursuant to Section 3.2(c) ,

21

and the Eligible Shares so surrendered shall forthwith be cancelled. If any portion of the Merger Consideration is to be registered in the name of a Person other than the Person in whose name the applicable surrendered Eligible Share is registered, it shall be a condition to the registration thereof that the surrendered Eligible Share be in proper form for transfer and that the Person requesting such delivery of the Merger Consideration pay any transfer or other similar Taxes required as a result of such registration in the name of a Person other than the registered holder of such Eligible Share or establish to the satisfaction of the Exchange Agent that such Tax has been paid or is not payable. Until surrendered as contemplated by this Section 3.2(b) , each Eligible Share shall be deemed at any time after the Effective Time to represent only the right to receive the Merger Consideration (and any amounts to be paid pursuant to Section 3.1(c) or Section 3.2(c) ) upon such surrender. No interest shall be paid or shall accrue on any amount payable pursuant to Section 3.1(c) or Section 3.2(c) .

(c)     Distributions with Respect to Unexchanged Shares . No dividends or other distributions with respect to shares of Mavericks Common Stock with a record date after the Effective Time shall be paid to the former holder of any unsurrendered Eligible Shares with respect to the shares of Mavericks Common Stock represented thereby, and no cash payment in lieu of fractional shares of Mavericks Common Stock shall be paid to any such former holder pursuant to Section 3.1(c) , until such Eligible Share has been surrendered in accordance with this Article III . Subject to applicable Law, following surrender of any such Eligible Share, there shall be paid to the former record holder thereof, without interest, (i) promptly after such surrender, the number of whole shares of Mavericks Common Stock issuable in exchange therefor pursuant to this Article III , together with any cash payable in lieu of any fractional share of Mavericks Common Stock to which such former holder is entitled pursuant to Section 3.1(c) and the amount of any dividends or other distributions with a record date after the Effective Time theretofore paid with respect to such whole shares of Mavericks Common Stock and (ii) at the appropriate payment date (if any), the amount of dividends or other distributions with a record date after the Effective Time and a payment date subsequent to such surrender payable with respect to such whole shares of Mavericks Common Stock.

(d)     No Further Ownership Rights in Rockets Common Stock; Closing of Transfer Books . All shares of Mavericks Common Stock issued upon the surrender for exchange of Eligible Shares in accordance with the terms of this Article III and any cash paid pursuant to Section 3.1(c) or Section 3.2(c) shall be deemed to have been issued or paid, respectively, in full satisfaction of all rights pertaining to the Eligible Shares. After the Effective Time, the stock transfer books of Rockets shall be closed, and there shall be no further registration of transfers on the stock transfer books of the Surviving Corporation of the Eligible Shares which were outstanding immediately prior to the Effective Time. If, after the Effective Time, Eligible Shares are presented to the Surviving Corporation or the Exchange Agent for any reason, they shall be cancelled and exchanged as provided in this Article III .

(e)     Termination of Exchange Fund . Any portion of the Exchange Fund (including the proceeds of any investments thereof) that remains undistributed to the former holders of Eligible Shares for one (1) year after the Effective Time shall be delivered to Mavericks upon demand, and, after such time, any former holders of Eligible Shares who have not then complied with this Article III shall thereafter look only to Mavericks for payment of their claim for the Merger Consideration, any cash in lieu of any fractional shares of Mavericks Common Stock pursuant to Section 3.1(c) and any dividends or distributions pursuant to Section 3.2(c) .

Any amounts under this Agreement that would be otherwise payable to a public official pursuant to any applicable abandoned property, escheat or similar Law shall, immediately prior to such time as such amounts would otherwise escheat to, or become property of, such public official, become, to the fullest extent permitted by Law, property of Mavericks or an Affiliate of Mavericks designated by Mavericks, free and clear of any claims or interest of any Person previously entitled thereto. Notwithstanding anything in this Agreement to the contrary none of Rockets, Mavericks (including as the Surviving Corporation), the Exchange Agent or any other Person shall be liable to any former holder of Eligible Shares for any amount properly delivered to a public official pursuant to any applicable abandoned property, escheat or similar Law.

(g)     Withholding Taxes . The Exchange Agent, Rockets and Mavericks (including as the Surviving Corporation) shall be entitled to deduct and withhold from the consideration otherwise payable under this Agreement to any Persons, such amounts as are required to be withheld or deducted under the Code or any provision of state, local or foreign Tax Law with respect to the making of such payment. To the extent that amounts are so withheld or deducted and paid over to the applicable Governmental Entity, such withheld or deducted amounts shall be treated for all purposes of this Agreement as having been paid to such Person in respect of which such deduction and withholding were made.
