2.1    Shelf Registration.

(a)    Shelf Registration Statement.

(i)    The Partnership shall (A) prepare and file with the Commission one Shelf Registration Statement and (B) cause such Shelf Registration Statement to become effective no later than the Target Effective Date.

(ii)    The Partnership will use its reasonable best efforts to cause the Shelf Registration Statement to be continuously effective under the Securities Act, with respect to any Holder, until the earlier of (A) three years after the Effective Date, extended for the aggregate time of all delays and suspensions under Section 2.1(b), or (B) such time as all Registrable Securities cease to be Registrable Securities (the “Effectiveness Period”).

2.2    Further Obligations. In connection with its obligations under this ARTICLE 2, the Partnership will:

(c)    if applicable, use its reasonable best efforts to promptly register or qualify the Registrable Securities covered by the Shelf Registration Statement under the securities or blue sky laws of such jurisdictions as the Holders may 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 be so qualified or to take any action that would subject it to general service of process in any such jurisdiction where it is not then so subject;

(d)    use its reasonable best efforts to comply with all applicable rules and regulations of the Commission;

(e)    use its reasonable best efforts to 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;

(f)    provide a transfer agent and registrar for all Registrable Securities covered by the Shelf Registration Statement;

(g)    if reasonably required by the Partnership’s transfer agent, the Partnership shall promptly deliver any authorizations, certificates and directions required by the transfer agent which authorize and direct the transfer agent to transfer Registrable Securities without legend upon sale by the Holder of such Registrable Securities under the Shelf Registration Statement;

(h)    promptly notify the Holders, at any time when a prospectus relating to Registrable Securities is required to be delivered under the Securities Act, upon discovery that, or upon the happening of any event as a result of which, the prospectus included in the Shelf Registration Statement, 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 light of the circumstances then existing, and if required by applicable law, promptly prepare, file with the Commission and furnish to the Holders a supplement to or an amendment of such prospectus as may be necessary so that such prospectus shall 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 light of the circumstances then existing;

(i)    use its reasonable best efforts to (i) prevent the issuance of any stop order or other suspension of effectiveness of the Shelf Registration Statement and, (ii) if such order is issued, obtain the withdrawal of any stop order or other suspension of effectiveness of the Shelf Registration Statement; and

The Partnership shall have no obligation to include Registrable Securities of a Holder in the Shelf Registration Statement or such amendment or supplement if such Holder has failed to furnish such information at least three Business Days prior to the first anticipated filing date of the Shelf Registration Statement or such amendment or supplement.

2.4    Expenses.

(a)    Certain Definitions.

“Registration Expenses” means all expenses incident to the Partnership’s performance under or compliance with this Agreement to effect the Registration, including all registration, filing, securities exchange listing and national securities exchange fees, all registration, filing, qualification and other fees and expenses of complying with securities or blue sky laws, fees of transfer agents and registrars, all word processing, duplicating and printing expenses of the Shelf Registration Statement and any preliminary prospectus, prospectus supplement or final prospectus, and the fees and disbursements of counsel and independent public accountants for the Partnership.

(b)    Expenses. The Partnership will pay all reasonable Registration Expenses, as determined in good faith, in connection with a shelf Registration, whether or not any sale is made pursuant to such shelf Registration. Except as otherwise provided in Section ‎2.5, the Partnership shall not be responsible for professional fees (including legal fees) incurred by Holders in connection with the exercise of such Holders’ rights hereunder.

2.5    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 Holder thereunder, its directors, officers, managers, members, partners, employees and agents and each Person, if any, who controls such Holder within the meaning of the Securities Act and the Exchange Act, and its directors, officers, managers, members, partners, employees or agents (collectively, the “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 Holder Indemnified Person becomes subject under the Securities Act, the Exchange Act or otherwise, insofar as such Losses arise out of or are based upon any untrue statement or alleged untrue statement of any material fact (in the case of any prospectus, in light of the circumstances under which such statement is made) contained in (which, for the avoidance of doubt, includes documents incorporated by reference in) the applicable Shelf Registration Statement, any preliminary prospectus, prospectus supplement or final prospectus contained therein, or any amendment or supplement thereof, or any free writing prospectus relating thereto, 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, in light of the circumstances under which they were made) not misleading, and will reimburse each such Holder Indemnified Person for any legal or other expenses reasonably incurred by them in connection with investigating, defending or resolving 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 Holder Indemnified Person. Such indemnity shall remain in full force and effect regardless of any investigation made by or on behalf of such Holder Indemnified Person, and shall survive the transfer of such securities by such Holder.

(b)    By Each Holder. Each Holder agrees severally but not jointly to indemnify and hold harmless the Partnership, its general partner and its general partner’s directors, officers, employees and agents and each Person, who, directly or indirectly, controls the Partnership within the meaning of the Securities Act or of the Exchange Act to the same extent as the foregoing indemnity from the Partnership to the Holders, but only with respect to information regarding such Holder furnished in writing by or on behalf of such Holder expressly for inclusion in the Shelf Registration Statement, any preliminary prospectus, prospectus supplement or final prospectus contained therein, or any amendment or supplement thereto or any free writing prospectus relating thereto. In no event shall the liability of any Holder be greater in amount than the dollar amount of the proceeds received by such Holder upon the sale of the Registrable Securities included in the Shelf Registration Statement giving rise to such indemnification obligation.

(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 to so notify the indemnifying party shall not relieve it from any liability that it may have to any indemnified party under this Section ‎2.5 (or otherwise), except to the extent that the indemnifying party is materially prejudiced by such failure. 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 ‎2.5 for any legal expenses subsequently incurred by such indemnified party in connection with the defense 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 satisfactory 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 may be entitled to indemnification hereunder without the consent of the indemnified party, unless the settlement thereof imposes no liability or obligation on, includes a complete and unconditional release from liability of, and does not contain any admission of wrongdoing by, the indemnified party.

(d)    Contribution. If for any reason the indemnification provided for in Section ‎2.5(a) and Section ‎2.5(b) is unavailable to an indemnified party or insufficient to hold it harmless, other than as expressly specified therein, then the indemnifying party shall contribute to the amount paid or payable by the indemnified party as a result of all such losses, claims, damages, expenses or liabilities (including reasonable attorneys’ fees and expenses) in such proportion as is appropriate to reflect the relative fault of the indemnified party and the indemnifying party, as well as any other relevant equitable considerations. The relative fault of such indemnifying party, on the one hand, and indemnified party, on the other hand, shall be determined by reference to, among other things, whether any action in question, including any untrue or alleged untrue statement of a material fact or omission or alleged omission to state a material fact, has been taken by, or relates to information supplied by, such indemnifying party or indemnified party, and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent any such action, statement or omission. 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 not guilty of such fraudulent misrepresentation. In no event shall the contribution obligation of any Holder be greater in amount than the dollar amount of the proceeds received by such Holder upon the sale of the Registrable Securities giving rise to such contribution obligation.

(e)    Other Indemnification. The provisions of this Section ‎2.5 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.

(f)    Survival. The obligations of this Section ‎2.5 shall survive the expiration or termination of this Agreement.

2.6    Rule 144 Reporting. With a view to making available the benefits of certain rules and regulations of the Commission that may permit the resale of the Registrable Securities without registration, so long as a Holder owns any Registrable Securities, the Partnership agrees to use its reasonable best 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 (or any similar provision then in effect), at all times from and after the date hereof;

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

(c)    furnish promptly upon reasonably request (i) to the extent accurate, a written statement of the Partnership that it has complied with the reporting requirements of Rule 144 under the Securities Act (or any similar provision then in effect) and (ii) unless otherwise available via the Commission’s EDGAR filing system, 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 Commission allowing such Holder to sell any such securities without registration; and

(d)    (i) reasonably cooperate, at the Partnership’s sole cost and expense, with such Holder in removing any restrictive legend from the certificates evidencing the Registrable Securities promptly following the expiration of the six-month holding period in respect of the Registrable Securities applicable to non-affiliates of the Partnership under Rule 144 under the Securities Act, including, if required, to cause the Partnership’s legal counsel to issue a legal opinion in favor of the Partnership’s transfer agent and instructing the transfer agent to issue new certificates evidencing such Registrable Securities free of any restrictive legend, and (ii) no later than the date that the Shelf Registration Statement is no longer effective, cause any restrictive legends to be removed from the certificates evidencing such Registrable Securities.

2.7    Transfer or Assignment of Registration Rights. The rights to cause the Partnership to register Registrable Securities under this Article II may not be transferred or assigned by each Holder to any transferee or assignee of Registrable Securities without receiving prior written consent from the Partnership; provided that the Permitted Transfer may be undertaken without the consent of the Partnership.

2.8    Lock-up Agreement. Except with respect to the Permitted Transfer, which may be undertaken without the consent of the Partnership and shall not constitute a breach of this Section ‎2.8, each Holder hereby agrees that it shall not, without the prior written consent of the Partnership, with respect to such Holder’s Registrable Securities, for a period of 90 days after the date hereof, (a) offer, pledge, sell, contract to sell, grant any option or contract to purchase, purchase any option or contract to sell, hedge the beneficial ownership of or otherwise dispose of, directly or indirectly, any Common Units or any securities convertible into, exercisable for or exchangeable for Common Units (whether such Common Units or any such securities are then owned by the Unitholder or are thereafter acquired), (b) enter into any swap or other arrangement that transfers to another, in whole or in part, any of the economic consequences of ownership of such securities, whether any such transaction described in clause (a) or (b) above is to be settled by delivery of Common Units or such other securities, in cash or otherwise, or (c) publicly disclose the intention to do any of the foregoing.

3.1    Notices. Any notice or other communication required or permitted hereunder shall be in writing and shall be delivered by hand, by facsimile transmission or electronic mail transmission, or by certified or registered mail, postage prepaid and return receipt requested. Notices shall be deemed to have been given upon delivery, if delivered by hand, three days after mailing, if mailed, and upon receipt of an appropriate electronic confirmation, if delivered by facsimile or electronic mail transmission. Notices shall be delivered to the parties at the addresses set forth below:

Any party may from time to time change its address or designee for notification purposes by giving the other parties prior notice in the manner specified above of the new address or the new designee and the subsequent date upon which the change shall be effective.

This Agreement, together with the Purchase Agreement and any related exhibits and schedules thereto, constitutes the sole and entire agreement of the parties to this Agreement with respect to the subject matter contained herein, and supersedes all prior and contemporaneous understandings and agreements, both written and oral, with respect to such subject matter. Notwithstanding the foregoing, in the event of any conflict between the terms and provisions of this Agreement and those of the Purchase Agreement, the terms and conditions of this Agreement shall control.

3.3    Successor and Assigns. This Agreement shall be binding upon and shall inure to the benefit of the parties hereto and their respective successors and permitted assigns. The Partnership may assign this Agreement at any time in connection with a sale or acquisition of the Partnership, whether by merger, consolidation, sale of all or substantially all of the Partnership’s assets, or similar transaction, without the consent of the Holders; provided, that the successor or acquiring Person agrees in writing to assume all of the Partnership’s rights and obligations under this Agreement.

3.4    No Third-Party Beneficiaries. This Agreement is for the sole benefit of the parties hereto and their respective successors and permitted assigns and nothing herein, express or implied, is intended to or shall confer upon any other Person any legal or equitable right, benefit or remedy of any nature whatsoever, under or by reason of this Agreement.

3.5    Headings and Captions. The headings and captions contained in this Agreement are included for purposes of convenience only, and shall not affect the meaning or interpretation of this Agreement or any term or provision contained herein.

3.6    Amendment, Modification and Waiver. Except as otherwise provided herein, the provisions of this Agreement may only be amended, modified, supplemented or waived with the prior written consent of the Partnership and the Sellers’ Representative. No waiver by any party or parties shall operate or be construed as a waiver in respect of any failure, breach or default not expressly identified by such written waiver, whether of a similar or different character, and whether occurring before or after that waiver. Except as otherwise set forth in this Agreement, no failure to exercise, or delay in exercising, any right, remedy, power or privilege arising from this Agreement shall operate or be construed as a waiver thereof; nor shall any single or partial exercise of any right, remedy, power or privilege hereunder preclude any other or further exercise thereof or the exercise of any other right, remedy, power or privilege.

3.7    Severability. If any term or other provision of this Agreement is invalid, illegal or incapable of being enforced under any applicable law or as a matter of public policy, all other conditions and provisions of this Agreement shall nevertheless remain in full force and effect. Upon such determination that any term or other provision is invalid, illegal or incapable of being enforced, the parties to this Agreement shall use reasonable efforts to modify this Agreement so as to effect the original intent of the parties as closely as possible in a mutually acceptable manner in order that the transactions contemplated by this Agreement be consummated as originally contemplated to the greatest extent possible.

3.8    Remedies. Each Holder, in addition to being entitled to exercise all rights granted by law, including recovery of damages, shall be entitled to specific performance of its rights under this Agreement. The Partnership acknowledges that monetary damages would not be adequate compensation for any loss incurred by reason of a breach by it of the provisions of this Agreement and the Partnership hereby agrees to waive the defense in any action for specific performance that a remedy at law would be adequate.

3.9    Governing Law; Waiver of Jury Trial.

(a)    This Agreement will be governed by and construed and enforced in accordance with the laws of the State of Delaware without regard to principles of conflicts of law. Any Proceeding (as defined in the Purchase Agreement) among the parties or arising out of or relating to this Agreement shall be instituted exclusively in the state and federal courts located in Houston, Texas, and each party irrevocably submits to the exclusive jurisdiction of such courts in any such Proceeding.

Notwithstanding the foregoing, any action for specific performance or other injunctive relief permitted under this Agreement may be instituted in any court that exercises appropriate jurisdiction over such action and the parties thereto.

(b)    EACH PARTY ACKNOWLEDGES AND AGREES THAT ANY CONTROVERSY WHICH MAY ARISE UNDER THIS AGREEMENT IS LIKELY TO INVOLVE COMPLICATED AND DIFFICULT ISSUES AND, THEREFORE, EACH SUCH PARTY IRREVOCABLY AND UNCONDITIONALLY WAIVES ANY RIGHT IT MAY HAVE TO A TRIAL BY JURY IN RESPECT OF ANY LEGAL ACTION ARISING OUT OF OR RELATING TO THIS AGREEMENT OR THE TRANSACTIONS CONTEMPLATED HEREBY.
