conversion or exercise of other securities, whether such right is currently exercisable or is exercisable only after the passage of time.

LOCK-UP; VOTING

Section 2.1 Lock-Up of Common Units. During the period prior to the date that is one hundred eighty (180) days after the Effective Date (excluding the Effective Date for purposes of calculating such date) (such date, the “Termination Date” and such period, the “Lock-Up Period”), the Seller Holders will not lend, offer, pledge, sell, contract to sell, sell any option or contract to purchase, purchase any option or contract to sell, grant any option, right, or warrant to purchase or otherwise transfer or dispose of, directly or indirectly, any Common Units, whether any such transaction is to be settled by delivery of Common Units or other securities, in cash, or otherwise. In the interest of clarity, nothing in this Section 2.1 shall restrict the Seller Holders from utilizing customary hedging strategies that may involve the pledge of Common Units as collateral until such time as the Common Units are ultimately disposed of on or after expiration of the Lock-Up Period. Further, nothing in this Section 2.1 shall prohibit or limit the ability of any Seller Holder to effect any transfer of Common Units (a) as a bona fide gift or gifts or any other similar transfer or distribution that does not involve a sale or other disposition for value, (b) to any such Person’s limited partners, members or stockholders as part of a distribution, (c) to any corporation, partnership or other entity that is an Affiliate of such Person, in each case of the forgoing clauses (a) through (c), so long as (i) such transfer does not occur prior to the consummation of the Election and (ii) the transferee agrees in writing to be bound by all the terms of this Section 2.1, (d) pursuant to a bona fide third party tender offer,

merger, consolidation or other similar transaction made to all holders of Common Units or (e) pursuant to an order of a court or regulatory agency.

Section 2.2 Voting of Covered Units. Provided that Buyer has complied with its covenants in Section 6.17(a) of the Purchase Agreement, during the period prior to the Termination Date, the Seller Holders irrevocably and unconditionally agree that at any meeting of unitholders of Buyer (whether annual or special and whether or not such meeting is adjourned or postponed), however called, including any adjournment or postponement thereof, or in connection with any written authorization or consent of unitholders of Buyer, each Seller Holder shall, and shall cause any holder of record of any Common Units beneficially owned by such Seller Holder, to:

(a) when a meeting is held, appear at such meeting or otherwise cause such Covered Units to be counted as present thereat for the purpose of establishing a quorum, and, when a record date is set for an action by written consent, respond to each request by Buyer for written consent, if any; and

(b) vote (or consent), or cause to be voted at such meeting (or validly execute and return and cause such consent to be granted within the time period requested by Buyer with respect to), all such Covered Units beneficially owned by such Seller Holder; as of the record date for the unitholder meeting or action by written consent in favor of:

(i) the Election; and

(ii) the proposal by Buyer to reflect any revisions as may be necessary or appropriate to reflect the Election and to amend the LTIP to proportionately increase the number of Common Units eligible for issuance under the LTIP after taking into account the Additional Common Units; provided, however, that Seller Holders shall not be required to, and shall not be required to cause any holder of record of any Common Units beneficially owned by Seller Holders, to vote in favor of (or consent to) such action if the aggregate Additional Common Units exceed 20,000,000 Common Units or the aggregate number of Common Units eligible for issuance under the LTIP exceeds twelve and a half percent (12.5%) of the sum of (A) the aggregate Common Units of Buyer outstanding at such time (which shall include the number of Common Units issued under the Purchase Agreement and the HM Purchase Agreement and issuable upon conversion of any Series A Preferred Units of Buyer that are issued on the Closing Date pursuant to the Preferred Equity Purchase Agreement assuming such Series A Preferred Units converted on the Closing Date (which amount for this purpose shall not exceed 5,945,946 Common Units), but without regard to any Common Units that were issued under the LTIP) and (B) the aggregate number of Common Units eligible for issuance under the LTIP.

(c) Notwithstanding anything to the contrary contained herein, the Seller Holders are entering into this Agreement solely in their capacity as beneficial owners of the Covered Units, and nothing herein is intended to or shall limit, affect or restrict any manager, general partner, director or officer of Seller Holders (including any appointee or representative of the Seller Holders) to the extent acting solely either in his or her capacity as a manager, general partner, director or officer of any member of Seller Holders (including voting on matters put to any board of directors, board of managers, general partner or any committee thereof, influencing

officers, employees, agents, management or the other directors of Seller Holders and taking any action or making any statement at any meeting of such board of directors, board of managers, general partner or any committee thereof) or in the exercise of his or her fiduciary duties as a manager, general partner, director or officer of the Seller Holders.
