ARTICLE 2

REGISTRATION RIGHTS

Section 2.01 Registration.

(a) Effectiveness Deadline. No later than 90 days following the Closing Date, the Partnership shall prepare and file a registration statement under the Securities Act to permit the public resale of Registrable Securities then outstanding from time to time as permitted by Rule 415 (or any similar provision then in effect) under the Securities Act with respect to all of the Registrable Securities (the “Registration Statement”). The Registration Statement filed pursuant to this Section 2.01(a) shall be on such appropriate registration form of the SEC as shall be selected by the Partnership so long as it permits the continuous offering of the Registrable Securities pursuant to Rule 415 (or any similar provision then in effect) under the Securities Act at the then prevailing market prices. The Partnership shall use its commercially reasonable efforts to cause the Registration Statement to become effective not later than 180 days following the Closing Date. Any Registration Statement shall provide for the resale pursuant to any method or combination of methods legally available to, and requested by, the Holders of any and all Registrable Securities covered by such Registration Statement. The Partnership shall use its commercially reasonable efforts to cause the Registration Statement filed pursuant to this Section 2.01(a) to be effective, supplemented and amended to the extent necessary to ensure that it is available for the resale of all Registrable Securities by the Holders until all Registrable Securities covered by such Registration Statement have ceased to be Registrable Securities (the “Effectiveness Period”). The Registration Statement when effective (including the documents incorporated therein by reference) will comply as to form in all material respects with all applicable requirements of the Securities Act and the Exchange Act and will not contain an untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary to make the statements therein not misleading (in the case of any prospectus contained in such Registration Statement, in the light of the circumstances under which a statement is made). As soon as practicable following the date that the Registration Statement becomes effective, but in any event within two (2) Business Days of such date, the Partnership shall provide the Holders with written notice of the effectiveness of the Registration Statement.

(b) Failure to Go Effective. If the Registration Statement required by Section 2.01(a) is not declared effective within 180 days after the Closing Date, then each Holder shall be entitled to a payment (with respect to the Transaction Units of each such Holder), as liquidated damages and not as a penalty, of 0.25% of the Liquidated Damages Multiplier per 30-day period, that shall accrue daily, for the first 60 days following the 180th day, increasing by an additional 0.25% of the Liquidated Damages Multiplier per 30-day period, that shall accrue daily, for each subsequent 60 days (i.e., 0.5% for 61-120 days following the 180^th day, 0.75% for 121-180 days following the 180^th day, and 1.0% thereafter), up to a maximum of 1.00% of the Liquidated Damages Multiplier per 30-day period (the “Liquidated Damages”). The Liquidated Damages payable pursuant to the immediately preceding sentence shall be payable within ten (10) Business Days after the end of each such 30-day period. Any Liquidated Damages shall be paid to each Holder in immediately available funds; provided, however, if the Partnership certifies that it is unable to pay Liquidated Damages in cash because such payment would result in a breach under a credit facility or other debt instrument, then the Partnership may pay the Liquidated Damages in kind in the form of the issuance of additional Common Units. Upon any

- 4 -

issuance of Common Units as Liquidated Damages, the Partnership shall promptly (i) prepare and file an amendment to the Registration Statement prior to its effectiveness adding such Common Units to such Registration Statement as additional Registrable Securities and (ii) prepare and file a supplemental listing application with the NYSE (or such other market on which the Registrable Securities are then listed and traded) to list such additional Common Units. The determination of the number of Common Units to be issued as Liquidated Damages shall be equal to the amount of Liquidated Damages divided by the volume-weighted average price of the Common Units on the NYSE (or such other market on which the Registrable Securities are then listed and traded) over the consecutive ten (10) trading day period ending on the close of trading on the trading day immediately preceding the date on which the Liquidated Damages payment is due. The accrual of Liquidated Damages to a Holder shall cease at the earlier of (i) the Registration Statement becoming effective or (ii) when such Holder no longer holds Registrable Securities, and any payment of Liquidated Damages shall be prorated for any period of less than 30 days in which the payment of Liquidated Damages ceases.

Section 2.02 Piggyback Rights.

(a) Participation. If the Partnership proposes to file (i) a shelf registration statement other than the Registration Statement contemplated by Section 2.01(a), (ii) a prospectus supplement to an effective shelf registration statement, other than the Registration Statement contemplated by Section 2.01(a) and Holders may be included without the filing of a post-effective amendment thereto or (iii) a registration statement, other than a shelf registration statement, in each case, for the sale of Common Units in an Underwritten Offering for its own account and/or another Person, then as soon as practicable following the engagement of counsel by the Partnership to prepare the documents to be used in connection with an Underwritten Offering, the Partnership shall give notice (including, but not limited to, notification by electronic mail) of such proposed Underwritten Offering to each Holder (together with its Affiliates) holding at least $1.0 million of the then-outstanding Registrable Securities (based on the Issue Price) and such notice shall offer such Holders the opportunity to include in such Underwritten Offering such number of Registrable Securities (the “Included Registrable Securities”) as each such Holder may request in writing; provided, however, that if the Partnership has been advised by the Managing Underwriter that the inclusion of Registrable Securities for sale for the benefit of the Holders will have an adverse effect on the price, timing or distribution of the Common Units in the Underwritten Offering, then (A) if no Registrable Securities can be included in the Underwritten Offering in the opinion of the Managing Underwriter, the Partnership shall not be required to offer such opportunity to the Holders or (B) if any Registrable Securities can be included in the Underwritten Offering in the opinion of the Managing Underwriter, then the amount of Registrable Securities to be offered for the accounts of Holders shall be determined based on the provisions of Section 2.02(b). Any notice required to be provided in this Section 2.02(a) to Holders shall be provided on a Business Day pursuant to Section 3.01 hereof and receipt of such notice shall be confirmed by the Holder. Each such Holder shall then have two (2) Business Days (or one (1) Business Day in connection with any overnight or bought Underwritten Offering) after notice has been delivered to request in writing the inclusion of Registrable Securities in the Underwritten Offering. If no written request for inclusion from a Holder is received within the specified time, each such Holder shall have no further right to participate in such Underwritten Offering. If, at any time after giving written notice of its intention to undertake an Underwritten Offering and prior to the closing of such

- 5 -

Underwritten Offering, the Partnership shall determine for any reason not to undertake or to delay such Underwritten Offering, the Partnership may, at its election, give written notice of such determination to the Selling Holders, and (x) in the case of a determination not to undertake such Underwritten Offering, shall be relieved of its obligation to sell any Included Registrable Securities in connection with such terminated Underwritten Offering and (y) in the case of a determination to delay such Underwritten Offering, shall be permitted to delay offering any Included Registrable Securities for the same period as the delay in the Underwritten Offering. Any Selling Holder shall have the right to withdraw such Selling Holder’s request for inclusion of such Selling Holder’s Registrable Securities in such Underwritten Offering by giving written notice to the Partnership of such withdrawal at or prior to the time of pricing of such Underwritten Offering. Any Holder may deliver written notice (an “Opt-Out Notice”) to the Partnership requesting that such Holder not receive notice from the Partnership of any proposed Underwritten Offering; provided, however, that such Holder may later revoke any such Opt-Out Notice in writing (which Opt-Out Notice shall be effective as to an Underwritten Offering provided the Partnership received such Opt-Out Notice at least ten (10) Business Days prior to the day of pricing of such Underwritten Offering (or two (2) Business Days prior to the day of pricing in the case of an overnight or bought Underwritten Offering). Following receipt of an Opt-Out Notice from a Holder (unless subsequently revoked), the Partnership shall not be required to deliver any notice to such Holder pursuant to this Section 2.02(a) and such Holder shall no longer be entitled to participate in Underwritten Offerings by the Partnership pursuant to this Section 2.02(a).

(b) Priority. If the Managing Underwriter of any proposed Underwritten Offering advises the Partnership that the total amount of Registrable Securities that the Selling Holders and any other Persons intend to include in such offering exceeds the number that can be sold in such offering without being likely to have an adverse effect on the price, timing or distribution of the Common Units offered or the market for the Common Units, then the Common Units to be included in such Underwritten Offering shall include the number of Registrable Securities that such Managing Underwriter advises the Partnership can be sold without having such adverse effect, with such number to be allocated (i) first, to the Partnership and (ii) second, pro rata among the Selling Holders who have requested participation in such Underwritten Offering and any other holder of securities of the Partnership having rights of registration that are neither expressly senior nor subordinated to the Registrable Securities (the “Parity Securities”). The pro rata allocations for each Selling Holder who has requested participation in such Underwritten Offering shall be the product of (a) the aggregate number of Registrable Securities proposed to be sold in such Underwritten Offering multiplied by (b) the fraction derived by dividing (x) the number of Registrable Securities owned on the Closing Date by such Selling Holder by (y) the aggregate number of Registrable Securities owned on the Closing Date by all Selling Holders plus the aggregate number of Parity Securities owned on the Closing Date by all holders of Parity Securities that are participating in the Underwritten Offering.

(c) Termination of Piggyback Registration Rights. Each Holder’s rights under Section 2.02 shall terminate upon such Holder (together with its Affiliates) ceasing to hold at least $1.0 million of Registrable Securities (based on the Issue Price).

- 6 -

Section 2.03 Delay Rights.

(a) Notwithstanding anything to the contrary contained herein, the Partnership may, upon written notice to any Selling Holder whose Registrable Securities are included in the Registration Statement or other registration statement contemplated by this Agreement, suspend such Selling Holder’s use of any prospectus which is a part of the Registration Statement or other registration statement (in which event the Selling Holder shall discontinue sales of the Registrable Securities pursuant to the Registration Statement or other registration statement contemplated by this Agreement but may settle any previously made sales of Registrable Securities) if (i) the Partnership is pursuing an acquisition, merger, reorganization, disposition, financing or other similar transaction or other corporate transaction and the Partnership determines in good faith that the Partnership’s ability to pursue or consummate such a transaction would be materially adversely affected by any required disclosure of such transaction in the Registration Statement or other registration statement or (ii) the Partnership has experienced some other material non-public event the disclosure of which at such time, in the good faith judgment of the Partnership, would materially adversely affect the Partnership; provided, however, in no event shall the Selling Holders be suspended from selling Registrable Securities pursuant to the Registration Statement or other registration statement for a period that exceeds an aggregate of 60 days in any 180-day period or 105 days in any 365-day period, in each case, exclusive of days covered by any lock-up agreement executed by a Selling Holder in connection with any Underwritten Offering. Upon disclosure of such information or the termination of the condition described above, the Partnership shall provide prompt notice to the Selling Holders whose Registrable Securities are included in the Registration Statement and shall promptly terminate any suspension of sales it has put into effect and shall take such other reasonable actions to permit registered sales of Registrable Securities as contemplated in this Agreement.

(b) If (i) the Selling Holders shall be prohibited from selling their Registrable Securities under the Registration Statement or other registration statement contemplated by this Agreement as a result of a suspension pursuant to the immediately preceding paragraph in excess of the periods permitted therein or (ii) the Registration Statement or other registration statement contemplated by this Agreement is filed and declared effective but, during the Effectiveness Period, shall thereafter cease to be effective or fail to be usable for its intended purpose without being succeeded within 30 days by a post-effective amendment thereto, a supplement to the prospectus or a report filed with the SEC pursuant to Section 13(a), 13(c), 14 or l5(d) of the Exchange Act, then, until the suspension is lifted or a post-effective amendment, supplement or report is filed with the SEC, but not including any day on which a suspension is lifted or such amendment, supplement or report is filed and declared effective, if applicable, the Partnership shall pay the Selling Holders an amount equal to the Liquidated Damages, following the earlier of (x) the date on which the suspension period exceeded the permitted period and (y) the thirty-first (31st) day after the Registration Statement or other registration statement contemplated by this Agreement ceased to be effective or failed to be useable for its intended purposes, as liquidated damages and not as a penalty (for purposes of calculating Liquidated Damages, the date in (x) or (y) above shall be deemed the “90th day,” as used in the definition of Liquidated Damages). For purposes of this paragraph, a suspension shall be deemed lifted on the date that notice that the suspension has been terminated is delivered to the Selling Holders. Liquidated Damages shall cease to accrue pursuant to this paragraph upon the Registrable Securities of such Holder becoming eligible for resale without restriction and without the need for current public information under any section of Rule 144 (or any similar provision then in effect) under the

- 7 -

Securities Act, assuming that such Holder is not an Affiliate of the Partnership, and any payment of Liquidated Damages shall be prorated for any period of less than 30 days in which the payment of Liquidated Damages ceases.

Section 2.04 Underwritten Offerings.

(a) General Procedures. In connection with any Underwritten Offering under this Agreement, the Partnership shall be entitled to select the Managing Underwriter. In connection with an Underwritten Offering contemplated by this Agreement in which a Selling Holder participates, each Selling Holder and the Partnership shall be obligated to enter into an underwriting agreement that contains such representations and warranties, covenants, indemnities and other rights and obligations as are customary in underwriting agreements for firm commitment offerings of securities. No Selling Holder may participate in such Underwritten Offering unless such Selling Holder agrees to sell its Registrable Securities on the basis provided in such underwriting agreement and completes and executes all questionnaires, powers of attorney, indemnities and other documents reasonably required under the terms of such underwriting agreement. Each Selling Holder may, at its option, require that any or all of the representations and warranties by, and the other agreements on the part of, the Partnership to and for the benefit of such underwriters also be made to and for such Selling Holder’s benefit and that any or all of the conditions precedent to the obligations of such underwriters under such underwriting agreement also be conditions precedent to its obligations. No Selling Holder shall be required to make any representations or warranties to or agreements with the Partnership or the underwriters other than representations, warranties or agreements regarding such Selling Holder, its authority to enter into such underwriting agreement and to sell, and its ownership of, the securities being registered on its behalf, its intended method of distribution and any other representation required by Law; provided, however, that if the Selling Holder is requested or required to make such representations, warranties or agreements that are not acceptable to such Selling Holder, such Selling Holder shall have the right to withdraw from such underwritten offering as provided herein. If any Selling Holder disapproves of the terms of an underwriting, such Selling Holder may elect to withdraw therefrom by notice to the Partnership and the Managing Underwriter; provided, however, that such withdrawal must be made up to and including the time of pricing of such Underwritten Offering. No such withdrawal shall affect the Partnership’s obligation to pay Registration Expenses. The Partnership’s management may but shall not be required to participate in a roadshow or similar marketing effort in connection with any Underwritten Offering.

(b) No Demand Rights. Notwithstanding any other provision of this Agreement, no Holder shall be entitled to any “demand” rights or similar rights that would require the Partnership to effect an Underwritten Offering solely on behalf of the Holders.

Section 2.05 Sale Procedures. In connection with its obligations under this Article II, the Partnership will, as promptly as reasonably practicable:

(a) prepare and file with the SEC such amendments and supplements to the Registration Statement and the prospectus or prospectus supplement used in connection therewith as may be necessary to keep the Registration Statement effective for the Effectiveness Period and as may be necessary to comply with the provisions of the Securities Act with respect to the disposition of all Registrable Securities covered by the Registration Statement;

- 8 -

(b) if a prospectus or prospectus supplement will be used in connection with the marketing of an Underwritten Offering from the Registration Statement and the Managing Underwriter notifies the Partnership in writing that, in the sole judgment of such Managing Underwriter, inclusion of detailed information in such prospectus or prospectus supplement is of material importance to the success of the Underwritten Offering of such Registrable Securities, the Partnership shall use its commercially reasonable efforts to include such information in such prospectus or prospectus supplement;

(c) furnish to each applicable Holder (i) as far in advance as reasonably practicable before filing the Registration Statement or any other registration statement contemplated by this Agreement or any amendment or supplement thereto, upon request, copies of reasonably complete drafts of all such documents proposed to be filed (including exhibits and each document incorporated by reference therein to the extent then required by the rules and regulations of the SEC) and provide each such Holder the opportunity to object to any information pertaining to such Holder and its plan of distribution that is contained therein and make the corrections reasonably requested by such Holder with respect to such information prior to filing the Registration Statement or such other registration statement or amendment or supplement thereto and (ii) such number of copies of the Registration Statement or such other registration statement and the prospectus or prospectus supplement included therein and any amendments and supplements thereto as such Holder may reasonably request in order to facilitate the public sale or other disposition of the Registrable Securities covered by such Registration Statement or other registration statement;

(d) if applicable, use its commercially reasonable efforts to register or qualify the Registrable Securities covered by the Registration Statement or any other registration statement contemplated by this Agreement under the securities or blue sky laws of such jurisdictions as the applicable Holders or, in the case of an Underwritten Offering, the Managing Underwriter, shall reasonably request; provided, however, that the Partnership will not be required to qualify generally to transact business in any jurisdiction where it is not then required to so qualify or to take any action that would subject it to general service of process in any jurisdiction where it is not then so subject;

(e) promptly notify each Selling Holder, at any time when a prospectus relating thereto is required to be delivered by any of them under the Securities Act, of (i) the filing of the Registration Statement or any other registration statement contemplated by this Agreement or any prospectus or prospectus supplement to be used in connection therewith, or any amendment or supplement thereto, and, with respect to such Registration Statement or any other registration statement or any post-effective amendment thereto, when the same has become effective; and (ii) the receipt of any written comments from the SEC with respect to any filing referred to in clause (i) and any written request by the SEC for amendments or supplements to the Registration Statement or any other registration statement or any prospectus or prospectus supplement thereto;

- 9 -

(f) immediately notify each Selling Holder of (i) the happening of any event as a result of which the prospectus or prospectus supplement contained in the Registration Statement or any other registration statement contemplated by this Agreement, as then in effect, includes an untrue statement of a material fact or omits to state any material fact required to be stated therein or necessary to make the statements therein not misleading (in the case of any prospectus or prospectus supplement contained therein, in the light of the circumstances under which a statement is made); (ii) the issuance or express threat of issuance by the SEC of any stop order suspending the effectiveness of the Registration Statement or any other registration statement contemplated by this Agreement, or the initiation of any proceedings for that purpose; or (iii) the receipt by the Partnership of any notification with respect to the suspension of the qualification of any Registrable Securities for sale under the applicable securities or blue sky laws of any jurisdiction. Following the provision of such notice, the Partnership agrees to as promptly as practicable amend or supplement the prospectus or prospectus supplement or take other appropriate action so that the prospectus or prospectus supplement does not include an untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary to make the statements therein not misleading in the light of the circumstances then existing and to take such other commercially reasonable action as is necessary to remove a stop order, suspension, threat thereof or proceedings related thereto;

(g) upon request and subject to appropriate confidentiality obligations, furnish to each Selling Holder copies of any and all transmittal letters or other correspondence with the SEC or any other governmental agency or self-regulatory body or other body having jurisdiction (including any domestic or foreign securities exchange) relating to such offering of Registrable Securities;

(h) in the case of an Underwritten Offering, furnish upon request, (i) an opinion of counsel for the Partnership dated the date of the closing under the underwriting agreement and (ii) comfort letter(s) dated the pricing date of such Underwritten Offering and letter(s) of like kind dated the date of the closing under the underwriting agreement, in each case, signed by the independent public accountants who have certified the Partnership’s financial statements included or incorporated by reference into the applicable registration statement, and each of the opinion and the comfort letter shall be in customary form and covering substantially the same matters with respect to such registration statement (and the prospectus and any prospectus supplement included therein) as have been customarily covered in opinions of issuer’s counsel and in accountants’ letters delivered to the underwriters in Underwritten Offerings of securities by the Partnership and such other matters as such underwriters and Selling Holders may reasonably request;

(i) otherwise use its commercially reasonable efforts to comply with all applicable rules and regulations of the SEC, and make available to its security holders, as soon as reasonably practicable, an earnings statement which shall satisfy the provisions of Section 11(a) of the Securities Act and Rule 158 promulgated thereunder;

(j) make available to the appropriate representatives of the Managing Underwriter and Selling Holders access to such information and Partnership personnel as is reasonable and customary to enable such parties to establish a due diligence defense under the Securities Act; provided, that the Partnership need not disclose any non-public information to any such representative unless and until such representative has entered into a confidentiality agreement with the Partnership;

- 10 -

(k) cause all Registrable Securities registered pursuant to this Agreement to be listed on each securities exchange or nationally recognized quotation system on which similar securities issued by the Partnership are then listed;

(l) use its commercially reasonable efforts to cause the Registrable Securities to be registered with or approved by such other governmental agencies or authorities as may be necessary by virtue of the business and operations of the Partnership to enable the Selling Holders to consummate the disposition of such Registrable Securities;

(m) provide a transfer agent for all Registrable Securities covered by such registration statement not later than the effective date of such registration statement;

(n) enter into customary agreements and take such other actions as are reasonably requested by the Selling Holders or the underwriters, if any, in order to expedite or facilitate the disposition of such Registrable Securities; and

(o) if requested by a Selling Holder, (i) incorporate in a prospectus or prospectus supplement or post-effective amendment to the Registration Statement or any other registration statement contemplated by this Agreement such information as such applicable Holder reasonably requests to be included therein relating to the sale and distribution of Registrable Securities, including information with respect to the number of Registrable Securities being offered or sold, the purchase price being paid therefor and any other terms of the offering of the Registrable Securities to be sold in such offering and (ii) make all required filings of such prospectus or prospectus supplement or post-effective amendment to the Registration Statement or any other registration statement contemplated by this Agreement after being notified of the matters to be incorporated in such prospectus or prospectus supplement or post-effective amendment.

The Partnership will not name a Holder as an underwriter as defined in Section 2(a)(11) of the Securities Act in any registration statement without such Holder’s consent. If the staff of the SEC requires the Partnership to name any Holder as an underwriter as defined in Section 2(a)(11) of the Securities Act, and such Holder does not consent thereto, then such Holder’s Registrable Securities shall not be included on the Registration Statement, such Holder shall no longer be entitled to receive Liquidated Damages under this Agreement with respect thereto and the Partnership shall have no further obligations hereunder with respect to Registrable Securities held by such Holder.

Each applicable Holder, upon receipt of notice from the Partnership of the happening of any event of the kind described in subsection (f) of this Section 2.05, shall forthwith discontinue offers and sales of the Registrable Securities by means of a prospectus or prospectus supplement until such Holder’s receipt of the copies of the supplemented or amended prospectus or prospectus supplement contemplated by subsection (f) of this Section 2.05 or until it is advised in writing by the Partnership that the use of the prospectus or prospectus supplement may be resumed and has received copies of any additional or supplemental filings incorporated by

- 11 -

reference in the prospectus or prospectus supplement, and, if so directed by the Partnership, such Holder will, or will request the Managing Underwriter, if any, to deliver to the Partnership all copies in their possession or control of the prospectus or prospectus supplement covering such Registrable Securities current at the time of receipt of such notice.

Section 2.06 Cooperation by Holders. The Partnership shall have no obligation to include Registrable Securities of a Holder in the Registration Statement or any other registration statement contemplated by this Agreement or in an Underwritten Offering pursuant to Section 2.02(a) who has failed to timely furnish such information that the Partnership determines, after consultation with counsel, is reasonably required in order for such registration statement or prospectus or prospectus supplement, as applicable, to comply with the Securities Act.

Section 2.07 Restrictions on Public Sale by Holders of Registrable Securities. Each Holder agrees with the Partnership, if requested by the underwriters, to enter into a customary lock up agreement with underwriters of an Underwritten Offering providing such Holder will not effect any public sale or distribution of Registrable Securities during the 90 calendar day period beginning on the date of a prospectus or prospectus supplement filed with the SEC with respect to the pricing of any Underwritten Offering, provided that (a) the duration of the foregoing restrictions shall be no longer than the duration of the shortest restriction generally imposed by the underwriters on the Partnership or the officers, directors or any other Affiliate of the Partnership on whom a restriction is imposed and (b) the restrictions set forth in this Section 2.07 shall not apply to any Registrable Securities that are included in such Underwritten Offering by such Holder. In addition, this Section 2.07 shall not apply to any Holder that is not entitled to participate in such Underwritten Offering, whether because such Holder delivered an Opt-Out Notice prior to receiving notice of the Underwritten Offering or because such Holder holds less than $1.0 million of the then-outstanding Registrable Securities.

Section 2.08 Expenses. The Partnership will pay all reasonable Registration Expenses as determined in good faith, including, in the case of an Underwritten Offering, whether or not any sale is made pursuant to such Underwritten Offering. Each Selling Holder shall pay its pro rata share of all Selling Expenses in connection with any sale of its Registrable Securities hereunder. In addition, except as otherwise provided in Section 2.09 hereof, the Partnership shall not be responsible for legal fees incurred by Holders in connection with the exercise of such Holders’ rights hereunder.

Section 2.09 Indemnification.

(a) By the Partnership. In the event of a registration of any Registrable Securities under the Securities Act pursuant to this Agreement, the Partnership will indemnify and hold harmless each Selling Holder thereunder, its directors, officers, managers, employees and agents and each Person, if any, who controls such Selling Holder within the meaning of the Securities Act and the Exchange Act, and its directors, officers, employees or agents (collectively, the “Selling Holder Indemnified Persons”), against any losses, claims, damages, expenses or liabilities (including reasonable attorneys’ fees and expenses) (collectively, “Losses”), joint or several, to which such Selling Holder Indemnified Person may become subject under the Securities Act, the Exchange Act or otherwise, insofar as such Losses (or actions or proceedings, whether commenced or threatened, in respect thereof) arise out of or are

- 12 -

based upon any untrue statement or alleged untrue statement of any material fact (in the case of any prospectus or prospectus supplement, in light of the circumstances under which such statement is made) contained in the Registration Statement or any other registration statement contemplated by this Agreement, any preliminary prospectus or prospectus supplement, free writing prospectus or final prospectus or prospectus supplement contained therein, or any amendment or supplement thereof, or arise out of or are based upon the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein (in the case of a prospectus or prospectus supplement, in light of the circumstances under which they were made) not misleading, and will reimburse each such Selling Holder Indemnified Person for any legal or other expenses reasonably incurred by them in connection with investigating or defending any such Loss or actions or proceedings; provided, however, that the Partnership will not be liable in any such case if and to the extent that any such Loss arises out of or is based upon an untrue statement or alleged untrue statement or omission or alleged omission so made in conformity with information furnished by such Selling Holder Indemnified Person in writing specifically for use in the Registration Statement or such other registration statement contemplated by this Agreement, preliminary prospectus or prospectus supplement, free writing prospectus, final prospectus or prospectus supplement contained therein, or any amendment or supplement thereof. Such indemnity shall remain in full force and effect regardless of any investigation made by or on behalf of such Selling Holder Indemnified Person and shall survive the transfer of such securities by such Selling Holder.

(b) By Each Selling Holder. Each Selling Holder agrees severally and not jointly to indemnify and hold harmless the Partnership, the General Partner, its directors, officers, employees and agents and each Person, if any, who controls the Partnership within the meaning of the Securities Act or of the Exchange Act, and its directors, officers, employees and agents, to the same extent as the foregoing indemnity from the Partnership to the Selling Holders, but only with respect to information regarding such Selling Holder furnished in writing by or on behalf of such Selling Holder expressly for inclusion in the Registration Statement or any other registration statement contemplated by this Agreement, any preliminary prospectus or prospectus supplement, free writing prospectus or final prospectus or prospectus supplement contained therein, or any amendment or supplement thereof; provided, however, that the liability of each Selling Holder shall not be greater in amount than the dollar amount of the proceeds (net of any Selling Expenses) received by such Selling Holder from the sale of the Registrable Securities giving rise to such indemnification.

(c) Notice. Promptly after receipt by an indemnified party hereunder of notice of the commencement of any action, such indemnified party shall, if a claim in respect thereof is to be made against the indemnifying party hereunder, notify the indemnifying party in writing thereof, but the omission so to notify the indemnifying party shall not relieve it from any liability that it may have to any indemnified party other than under this Section 2.09. In any action brought against any indemnified party, it shall notify the indemnifying party of the commencement thereof. The indemnifying party shall be entitled to participate in and, to the extent it shall wish, to assume and undertake the defense thereof with counsel reasonably satisfactory to such indemnified party and, after notice from the indemnifying party to such indemnified party of its election so to assume and undertake the defense thereof, the indemnifying party shall not be liable to such indemnified party under this Section 2.09 for any legal expenses subsequently incurred by such indemnified party in connection with the defense

- 13 -

thereof other than reasonable costs of investigation and of liaison with counsel so selected; provided, however, that, (i) if the indemnifying party has failed to assume the defense or employ counsel reasonably acceptable to the indemnified party or (ii) 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 additional 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 reasonable expenses and fees of such separate counsel and other reasonable expenses related to such participation to be reimbursed by the indemnifying party as incurred. Notwithstanding any other provision of this Agreement, no indemnifying party shall settle any action brought against any indemnified party with respect to which such indemnified party is entitled to indemnification hereunder without the consent of the indemnified party, unless the settlement thereof imposes no liability or obligation on, and includes a complete and unconditional release from all liability of, the indemnified party.

(d) Contribution. If the indemnification provided for in this Section 2.09 is held by a court or government agency of competent jurisdiction to be unavailable to any indemnified party or is insufficient to hold them harmless in respect of any Losses, then each such indemnifying party, in lieu of indemnifying such indemnified party, shall contribute to the amount paid or payable by such indemnified party as a result of such Loss in such proportion as is appropriate to reflect the relative fault of the indemnifying party on the one hand and of such indemnified party on the other in connection with the statements or omissions that resulted in such Losses, as well as any other relevant equitable considerations; provided, however, that in no event shall such Selling Holder be required to contribute an aggregate amount in excess of the dollar amount of proceeds (net of Selling Expenses) received by such Selling Holder from the sale of Registrable Securities giving rise to such indemnification. The relative fault of the indemnifying party on the one hand and the indemnified party on the other shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission or alleged omission to state a material fact has been made by, or relates to, information supplied by such party, and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission. The parties hereto agree that it would not be just and equitable if contributions pursuant to this paragraph were to be determined by pro rata allocation or by any other method of allocation that does not take account of the equitable considerations referred to herein. The amount paid by an indemnified party as a result of the Losses referred to in the first sentence of this paragraph shall be deemed to include any legal and other expenses reasonably incurred by such indemnified party in connection with investigating or defending any Loss that is the subject of this paragraph. No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution from any Person who is not guilty of such fraudulent misrepresentation.

(e) Other Indemnification. The provisions of this Section 2.09 shall be in addition to any other rights to indemnification or contribution that an indemnified party may have pursuant to law, equity, contract or otherwise.

Section 2.10 Rule 144 Reporting. With a view to making available the benefits of certain rules and regulations of the SEC that may permit the sale of the Registrable Securities to the public without registration, the Partnership agrees to use its commercially reasonable efforts to:

(a) make and keep public information regarding the Partnership available, as those terms are understood and defined in Rule 144 under the Securities Act, at all times from and after the date hereof;

(b) file with the SEC in a timely manner all reports and other documents required of the Partnership under the Exchange Act at all times from and after the date hereof; and

(c) so long as a Holder owns any Registrable Securities, furnish, unless otherwise available via XXXXX, to such Holder forthwith upon request a copy of the most recent annual or quarterly report of the Partnership, and such other reports and documents so filed as such Holder may reasonably request in availing itself of any rule or regulation of the SEC allowing such Holder to sell any such securities without registration.

Section 2.11 Transfer or Assignment of Registration Rights. The rights to cause the Partnership to register Registrable Securities granted to the Initial Holders by the Partnership under this Article II may be transferred or assigned by any Initial Holder to one or more transferees or assignees of Registrable Securities; provided, however, that (a) unless the transferee or assignee is an Affiliate of, and after such transfer or assignment continues to be an Affiliate of, such Initial Holder, the amount of Registrable Securities transferred or assigned to such transferee or assignee shall represent at least $1.0 million of Registrable Securities (based on the Issue Price), (b) the Partnership is given written notice prior to any said transfer or assignment, stating the name and address of each such transferee or assignee and identifying the securities with respect to which such registration rights are being transferred or assigned and (c) each such transferee or assignee assumes in writing responsibility for its portion of the obligations of such Initial Holder under this Agreement.

Section 2.12 Limitation on Subsequent Registration Rights. From and after the date hereof, the Partnership shall not, without the prior written consent of the Holders of a majority of the Registrable Securities, enter into any agreement with any current or future holder of any securities of the Partnership that would allow such current or future holder to require the Partnership to include securities in any registration statement filed by the Partnership on a basis other than pari passu with, or expressly subordinate to the rights of, the Holders of Registrable Securities hereunder.

The existence of this right will not preclude any such Person from pursuing any other rights and remedies at law or in equity that such Person may have.

Section 3.07 Counterparts. This Agreement may be executed in any number of counterparts and by different parties hereto in separate counterparts, each of which counterparts, when so executed and delivered, shall be deemed to be an original and all of which counterparts, taken together, shall constitute but one and the same Agreement.

Section 3.11 Entire Agreement. This Agreement is intended by the parties as a final expression of their agreement and intended to be a complete and exclusive statement of the agreement and understanding of the parties hereto in respect of the subject matter contained herein. There are no restrictions, promises, warranties or undertakings, other than those set forth or referred to herein with respect to the rights granted by the Partnership set forth herein.

Section 3.12 Amendment.

under this Agreement or any documents or instruments delivered in connection herewith or therewith or for any claim based on, in respect of or by reason of such obligation or its creation, except in each case for any transferee or assignee of an Initial Holder hereunder.

Section 3.15 Independent Nature of Initial Holder’s Obligations. The obligations of each Initial Holder (and their permitted transferees and assignees) under this Agreement are several and not joint with the obligations of any other Initial Holder, and no Initial Holder shall be responsible in any way for the performance of the obligations of any other Initial Holder under this Agreement. Nothing contained herein, and no action taken by any Initial Holder pursuant thereto, shall be deemed to constitute the Initial Holders as a partnership, an association, a joint venture or any other kind of group or entity, or create a presumption that the Initial Holders are in any way acting in concert or as a group with respect to such obligations or the transactions contemplated by this Agreement. Each Initial Holder shall be entitled to independently protect and enforce its rights, including without limitation, the rights arising out of this Agreement, and it shall not be necessary for any other Initial Holder to be joined as an additional party in any proceeding for such purpose.
