SECTION 4.10                                      Reliance on Exemptions.  Each Purchaser understands that the Purchased Units are being offered and sold to such Purchaser in reliance upon specific exemptions from the registration requirements of United States federal and state securities laws and that the Partnership is relying upon the truth and accuracy of, and Purchaser’s compliance

15

SECTION 5.02                                      Return of Proceeds.  If the Acquisition is not consummated within two Business Days after the Anticipated Closing Date, or if any of the conditions set forth in Section 6.01 have not been satisfied or waived, and any Purchaser has paid its Aggregate Purchase Price into the Partnership Bank Account in advance of the Closing, then on or prior to the third Business Day after the Anticipated Closing Date (or if the Partnership receives a written request by any such Purchaser on or before 1:00 pm Central time on the Anticipated Closing Date and the Acquisition is not consummated by 3:00 pm Central time on the Anticipated Closing Date, then not later than the close of business on the Anticipated Closing Date), the Partnership shall return such Aggregate Purchase Price, without interest, to such Purchaser.

SECTION 5.03                                      Disclosure; Public Filings.  The Partnership may, without prior written consent or notice, (i) file the Transaction Agreements as exhibits to Exchange Act reports and (ii) disclose such information with respect to any Purchaser as required by applicable Law or the

SECTION 5.06                                      Subsequent Offerings.  Without the prior written consent of the holders of a majority of all the Common Units issued and sold to the Purchasers pursuant to this Agreement, during the period from and after the date of this Agreement until the end of the 45th day after the Closing Date, the Partnership shall not grant, issue or sell any Common Units or any securities convertible into or exchangeable or exercisable for Common Units, or take any other action that may result in the issuance of any of the foregoing; provided, however, that the Partnership may issue Common Units or any securities convertible or exchangeable into Common Units as payment of any part of the purchase price for businesses that are acquired by the Partnership or its Subsidiaries (provided that any recipient of such Common Units must agree in writing to be bound by the terms of this Section 5.06 for the remaining term of such 45-day period); provided, further that no such consent shall be required in respect of the issuance of Common Units pursuant to the LTIP or upon the exercise of options to purchase Common Units granted pursuant to the LTIP or with respect to the issuance of Common Units upon the vesting of phantom or restricted units granted pursuant to the LTIP.

Such special allocations will occur upon the earlier to occur of any taxable period of the Partnership ending upon, or after, (a) an event described in Section 5.5(d) of the Partnership Agreement or a sale of all or substantially all of the assets of the Partnership occurring after the date of the issuance of the Purchased Units, or (b) the

17

transfer of the Purchased Units to a Person that is not an Affiliate of the Purchaser, in which case, such allocation shall be made only with respect to the Purchased Units so transferred.

SECTION 7.01                                      Indemnification by the Partnership.  The Partnership agrees to indemnify each Purchaser and its Representatives (collectively, “Purchaser Related Parties”) (a) from costs, losses, liabilities, damages, or expenses, and (b) hold each of them harmless against, any and all actions, suits, proceedings (including any investigations, litigation or inquiries), demands, and causes of action as a result of, arising out of, or in any way related to the breach of any of the representations, warranties or covenants of the Partnership contained herein, and in connection therewith, and promptly upon demand, pay or reimburse each of them for all costs, losses, liabilities, damages, or expenses of any kind or nature whatsoever, including, without limitation, the reasonable fees and disbursements of counsel and all other reasonable expenses incurred in connection with investigating, defending or preparing to defend any such matter that may be incurred by them or asserted against or involve any of them, provided that such claim for indemnification relating to a breach of the representations or warranties is made prior to the expiration of such representations or warranties to the extent applicable; and provided further, that no Purchaser Related Party shall be entitled to recover special, consequential (including lost profits) or punitive damages under this Section 7.01.

SECTION 7.02                                      Indemnification by Purchasers.  Each Purchaser agrees, severally and not jointly, to indemnify the Partnership, the General Partner and their respective Representatives (collectively, “Partnership Related Parties”) from, and hold each of them harmless against, any and all actions, suits, proceedings (including any investigations, litigation, or inquiries), demands and causes of action and, in connection therewith, and promptly upon demand, pay or reimburse each of them for all costs, losses, liabilities, damages, or expenses of any kind or nature whatsoever, including, without limitation, the reasonable fees and disbursements of counsel and all other reasonable expenses incurred in connection with investigating, defending or preparing to defend any such matter that may be incurred by them or asserted against or involve any of them as a result of, arising out of, or in any way related to the breach of any of the representations, warranties or covenants of such Purchaser contained herein; provided that such claim for indemnification relating to a breach of a representation or warranty is made prior to the expiration of such representation or warranty; and provided further, that no Partnership Related Party shall be entitled to recover special, consequential (including lost profits) or punitive damages; provided further, that absent fraud, bad faith, gross negligence or willful misconduct

21

on the part of a Purchaser, in no event will such Purchaser be liable under this Section 7.02 for any amount in excess of its Aggregate Purchase Price.

SECTION 7.03                                      Indemnification Procedure.  Promptly after any Partnership Related Party or Purchaser Related Party (hereinafter, the “Indemnified Party”) has received notice of any indemnifiable claim hereunder, or the commencement of any action, suit or proceeding by a third party, which the Indemnified Party believes in good faith is an indemnifiable claim under this Agreement, the Indemnified Party shall give the indemnitor hereunder (the “Indemnifying Party”) written notice of such claim or the commencement of such action, suit or proceeding, but failure to so notify the Indemnifying Party will not relieve the Indemnifying Party from any liability it may have to such Indemnified Party hereunder except to the extent that the Indemnifying Party is materially prejudiced by such failure. Such notice shall state the nature and the basis of such claim to the extent then known. The Indemnifying Party shall have the right to defend and settle, at its own expense and by its own counsel who shall be reasonably acceptable to the Indemnified Party, any such matter as long as the Indemnifying Party pursues the same diligently and in good faith. If the Indemnifying Party undertakes to defend or settle, it shall promptly notify the Indemnified Party of its intention to do so, and the Indemnified Party shall cooperate with the Indemnifying Party and its counsel in all commercially reasonable respects in the defense thereof and the settlement thereof.

Such cooperation of the Indemnified Party shall be at the cost of the Indemnifying Party. After the Indemnifying Party has notified the Indemnified Party of its intention to undertake to defend or settle any such asserted liability, and for so long as the Indemnifying Party diligently pursues such defense, the Indemnifying Party shall not be liable for any additional legal expenses incurred by the Indemnified Party in connection with any defense or settlement of such asserted liability; provided, however, that the Indemnified Party shall be entitled (i) at its expense, to participate in the defense of such asserted liability and the negotiations of the settlement thereof and (ii) if (A) the Indemnifying Party has failed to assume the defense or employ counsel reasonably acceptable to the Indemnified Party or (B) if the defendants in any such action include both the Indemnified Party and the Indemnifying Party and counsel to the Indemnified Party shall have concluded that there may be reasonable defenses available to the Indemnified Party that are different from those available to the Indemnifying Party, then the Indemnified Party shall have the right to select a separate counsel and to assume such legal defense and otherwise to participate in the defense of such action, with the expenses and fees of such separate counsel and other expenses related to such participation to be reimbursed by the Indemnifying Party as incurred. Notwithstanding any other provision of this Agreement, the Indemnifying Party shall not settle any indemnified claim without the consent of the Indemnified Party, unless the settlement thereof imposes no liability or obligation on, involves no admission of wrongdoing or malfeasance by, and includes a complete release from liability of, the Indemnified Party.

SECTION 8.06                                      Removal of Legend.  The Partnership, at its sole cost, shall remove the legend described in in Section 4.09 (or instruct its transfer agent to so remove such legend) from the certificates evidencing Common Units issued and sold to each Purchaser pursuant to this Agreement if (i) a registration statement under the Securities Act permitting the public resale of such Common Units has become effective under the Securities Act, (ii) such Common Units are sold or transferred pursuant to Rule 144 (if the transferor is not an Affiliate of the Partnership), or (iii) such Common Units are eligible for sale under Rule 144, without the requirement for the Partnership to be in compliance with the current public information required under Rule 144(c)(1) (or Rule 144(i)(2), if applicable) as to such securities and without volume or manner-of-sale restrictions.  Each Purchaser agrees to provide the Partnership, its counsel and/or the transfer agent with evidence reasonably requested by it in order to cause the removal of the legend described in in Section 4.09, including without limitation an Instruction and Representation Letter in substantially the form attached to this Agreement as Exhibit E (an “Instruction and Representation Letter”).  Any fees (with respect to the transfer agent, Partnership counsel or otherwise) associated with the issuance of any legal opinion required by the Partnership’s transfer agent or the removal of such legend shall be borne by the Partnership.  If a legend is no longer required pursuant to the foregoing, the Partnership will no later than three (3) Business Days following the delivery by a Purchaser to the Partnership or the transfer agent (with notice to the Partnership) of a legended certificate or instrument representing Common Units (endorsed or with stock powers attached, signatures guaranteed, and otherwise in form necessary to affect the reissuance and/or transfer) and an Instruction and Representation Letter, deliver or cause to be delivered to such Purchaser a certificate or instrument (as the case may be) representing such Common Units that is free from all restrictive legends.  Certificates for Common Units free from all restrictive legends may be transmitted by the transfer agent to the Purchasers by crediting the account of the Purchaser’s prime broker with DTC as directed by such Purchaser.

SECTION 8.11                                      Recapitalization, Exchanges, Etc.  The provisions of this Agreement shall apply to the full extent set forth herein with respect to any and all equity interests of the Partnership or any successor or assign of the Partnership (whether by merger, consolidation, sale of assets or otherwise) that may be issued in respect of, in exchange for or in substitution of, the Purchased Units, and shall be appropriately adjusted for combinations, unit splits, recapitalizations and the like occurring after the date of this Agreement.
