The execution, delivery and performance of such Transaction Documents by the Purchaser and the consummation by it of the transactions contemplated thereby have been duly and validly authorized by all necessary legal partnership action on the part of the Purchaser, and no further consent or authorization by any other Person is required for the execution, delivery and performance of such Transaction Documents by the Purchaser and the consummation by the Purchaser of the transactions contemplated thereby. Each of the Transaction Documents to which the Purchaser is a party has been, or will be at each Closing, duly executed and delivered by the Purchaser, where applicable, and constitutes, or will constitute at each Closing, a legal, valid and binding obligation of the Purchaser, except as enforceability is limited by applicable bankruptcy, insolvency, fraudulent transfer, reorganization, moratorium or similar Laws from time to time in effect affecting creditors’ rights and remedies generally and by general principles of equity (regardless of whether such principles are considered in a proceeding in equity or at law).

Section 4.03 No Breach. The execution, delivery and performance of the Transaction Documents to which the Purchaser is a party by the Purchaser and the consummation by the Purchaser of the transactions contemplated thereby will not (a) conflict with or result in a breach or violation of any of the terms or provisions of, or constitute a default under, any material agreement to which the Purchaser is a party or by which the Purchaser is bound or to which any of the property or assets of the Purchaser is subject, (b) conflict with or result in any violation of the provisions of the Organizational Documents of the Purchaser, or (c) violate any Law of any Governmental Authority or body having jurisdiction over the Purchaser or the property or assets of the Purchaser, except in the case of clauses (a) and (c), for conflicts, breaches, violations or defaults as would not reasonably be expected to have a material adverse effect on the ability of the Purchaser to perform its obligations under the Transaction Documents or consummate the transactions contemplated thereby.

13

Section 4.04 Certain Fees. No fees or commissions are or will be payable by the Purchaser to brokers, finders or investment bankers with respect to the purchase of any of the Purchased Units or the consummation of the transactions contemplated by this Agreement except for fees or commissions for which no Partnership Party shall be responsible. The Purchaser agrees that it will indemnify and hold harmless the Partnership Parties from and against any and all claims, demands, or liabilities for broker’s, finder’s, placement, or other similar fees or commissions incurred by or on behalf of the Purchaser or alleged to have been incurred by or on behalf of the Purchaser in connection with the purchase of the Purchased Units or the consummation of the transactions contemplated by this Agreement.

Section 4.05 Unregistered Securities.

(a) Accredited Investor Status; Sophisticated Purchaser. The Purchaser is an “accredited investor” within the meaning of Rule 501 under the Securities Act and is able to bear the risk of its investment in the Purchased Units, the PIK Units and the Conversion Units, as applicable. The Purchaser has such knowledge and experience in financial and business matters that it is capable of evaluating the merits and risks of the purchase of the Purchased Units and the Conversion Units, as applicable.

(b) Information. The Purchaser and its Representatives have been furnished with all materials relating to the business, finances and operations of the Partnership that have been requested and materials relating to the offer and sale of, and investment in, the Purchased Units and Conversion Units, as applicable, that have been requested by the Purchaser. The Purchaser and its Representatives have been afforded the opportunity to ask questions of the Partnership and its Representatives. Neither such inquiries nor any other due diligence investigations conducted at any time by the Purchaser and its Representatives shall modify, amend or affect the Purchaser’s right (i) to rely on the Partnership’s representations and warranties in Article III above or (ii) to indemnification or any other remedy based on, or with respect to the accuracy or inaccuracy of, or compliance with, the representations, warranties, covenants and agreements in any Transaction Document. The Purchaser understands that its purchase of the Purchased Units involves a high degree of risk. The Purchaser has sought such accounting, legal and tax advice as it has considered necessary to make an informed investment decision with respect to its acquisition of the Purchased Units.

(c) Legends. The Purchaser understands that, until such time as the Purchased Units, the PIK Units and the Conversion Units, as applicable, have been sold pursuant to an effective registration statement under the Securities Act, or the Purchased Units, the PIK Units and the Conversion Units, as applicable, are eligible for resale pursuant to Rule 144 promulgated under the Securities Act without any restriction as to the number of securities as of a particular date that can then be immediately sold, the Purchased Units, the PIK Units and the Conversion Units, as applicable, will bear a restrictive legend as provided in the Partnership Agreement.

(d) Purchase Representation. The Purchaser is purchasing the Purchased Units for its own account and not with a view to distribution in violation of any securities Laws. The Purchaser has been advised and understands that neither the Purchased Units, the PIK Units nor the Conversion Units have been registered under the Securities Act or under the “blue sky” Laws of any jurisdiction and may be resold only if registered pursuant to the provisions of the Securities Act (or if eligible, pursuant to the provisions of Rule 144 promulgated under the Securities Act or pursuant to another available exemption from the registration requirements of the Securities Act).

14

(e) Rule 144. The Purchaser understands that there is no public trading market for the Series A Preferred Units, that none is expected to develop, that the Purchased Units are characterized as restricted securities under the federal securities Laws and that the Purchased Units, the PIK Units and the Conversion Units must be held indefinitely unless and until the Purchased Units, the PIK Units or the Conversion Units, as applicable, are registered under the Securities Act or an exemption from registration is available. The Purchaser has been advised of and is knowledgeable with respect to the provisions of Rule 144 promulgated under the Securities Act.

(f) Reliance by the Partnership. The Purchaser understands that the Purchased Units are being offered and sold in reliance on a transactional exemption from the registration requirements of federal and state securities Laws and that the Partnership is relying upon the truth and accuracy of the representations, warranties, agreements, acknowledgments and understandings of the Purchaser set forth herein in order to determine the applicability of such exemptions and the suitability of the Purchaser to acquire the Purchased Units and the PIK Units, and the Conversion Units issuable upon conversion thereof.

The Partnership agrees to indemnify the Purchaser and its Representatives (collectively, “Purchaser Related Parties”) from costs, losses, liabilities, damages or expenses of any kind or nature whatsoever, 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, promptly upon demand, pay or reimburse each of them for any and 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), whether or not involving a Third-Party Claim, as a result of, arising out of, or in any way related to (a) the failure of any of the representations or warranties made by the Partnership contained herein to be true and correct in all material respects (other than those representations and warranties contained in Section 3.01, Section 3.02, Section 3.03, Section 3.08, Section 3.10 or Section 3.12 or other representations and warranties that are qualified by materiality or Material Adverse Effect, which, in each case, shall be true and correct in all respects) when made and as of each Closing Date (except for any representations and warranties made as of a specific date, which shall be required to be true and correct as of such date only) or (b) the breach of any covenants of the Partnership contained herein; provided that, in the case of the immediately preceding clause (a), such claim for indemnification is made prior to the expiration of the survival period of such representation or warranty; provided, further, that for purposes of determining when an indemnification claim has been made, the date upon which the Purchaser Related Party shall have given notice (stating in reasonable detail the basis of the claim for indemnification) to the Partnership shall constitute the date upon which such claim has been made; and provided, further, that the aggregate liability of the Partnership to the Purchaser under this Section 6.01 shall not be greater in amount than the Base Purchase Price plus, if the Option is exercised, the Option Purchase Price. No Purchaser Related Party shall be entitled to recover special, indirect, exemplary, lost profits, speculative or punitive damages under this Section 6.01; provided, however, that such limitation shall not prevent any Purchaser Related Party from recovering under this Section 6.01 for any such damages to the extent that such damages are payable to a third party in connection with any Third-Party Claims.

Section 6.02 Indemnification by the Purchaser. The Purchaser agrees to indemnify each of the Partnership Parties and their respective Representatives (collectively, “Partnership Related Parties”) from, costs, losses, liabilities, damages, or expenses of any kind or nature whatsoever, 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, promptly upon demand, pay or reimburse each of them for any and 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), whether or not involving a Third-Party Claim, as a result of, arising out of, or in any way related to (a) the failure of any of the representations or warranties made by the Purchaser contained herein to be true and correct in all material respects (other than those representations and warranties contained in Section 4.01,

16

Section 4.02 or Section 4.04 or that in are qualified by materiality, which, in each case, shall be true and correct in all respects) when made and as of each Closing Date or (b) the breach of any of the covenants of the Purchaser contained herein; provided, however, that, in the case of the immediately preceding clause (a), such claim for indemnification relating to a breach of any representation or warranty is made prior to the expiration of the survival period of the representation or warranty; and provided, further, that for purposes of determining when an indemnification claim has been made, the date upon which a Partnership Related Party shall have given notice (stating in reasonable detail the basis of the claim for indemnification) to the Purchaser shall constitute the date upon which such claim has been made; and provided, further, that the liability of the Purchaser shall not be greater in amount than the sum of the Base Purchase Price plus, if the Option is exercised, the Option Purchase Price, plus any distributions paid to the Purchaser with respect to the Purchased Units, the PIK Units and the Conversion Units, if and as applicable. No Partnership Related Party shall be entitled to recover special, indirect, exemplary, lost profits, speculative or punitive damages under this Section 6.02; provided, however, that such limitation shall not prevent any Partnership Related Party from recovering under this Section 6.02 for any such damages to the extent that such damages are payable to a third party in connection with any Third-Party Claims.

Section 6.03 Indemnification Procedure.

(a) A claim for indemnification for any matter not involving a Third-Party Claim may be asserted by notice to the party from whom indemnification is sought; provided, however, that failure to so notify the Indemnifying Party shall not preclude the Indemnified Party from any indemnification which it may claim in accordance with this Article VI, except as otherwise provided in Section 6.01, Section 6.02 and Section 6.03.

(b) 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 Person, which the Indemnified Party believes in good faith is an indemnifiable claim under this Agreement (each a “Third-Party Claim”), the Indemnified Party shall give the indemnitor hereunder (the “Indemnifying Party”) written notice of such Third-Party Claim, which shall state the nature and basis of such Third-Party Claim to the extent then known; provided, however, that 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. 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, and in no event later than ten (10) days, 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 shall include, but shall not be limited to, furnishing the Indemnifying Party with any books, records and other information reasonably requested by the Indemnifying Party and in the Indemnified Party’s possession or control. 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

17

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, within 10 Business Days of when the Indemnified Party provides written notice of a Third-Party Claim, failed (1) to assume the defense or employ counsel reasonably acceptable to the Indemnified Party or (2) to notify the Indemnified Party of such assumption 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 or in addition to those available to the Indemnifying Party or if the interests of the Indemnified Party reasonably may be deemed to conflict with the interests of 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, and includes a complete release from liability of, and does not include any admission of wrongdoing or malfeasance by, the Indemnified Party.

Section 6.04 Tax Matters. All indemnification payments under this Article VI shall be adjustments to the Base Purchase Price plus, if the Option is exercised, the Option Purchase Price, except as otherwise required by applicable Law.
