Item 4. Description of Securities.

Not applicable.

Item 5. Interests of Named Experts and Counsel.

Not applicable.

Item 6. Indemnification of Directors and Officers.

Subject to any terms, conditions, or restrictions set forth in the partnership agreement, Section 17-108 of the Delaware Revised Uniform Limited Partnership Act empowers a Delaware limited partnership to indemnify and hold harmless any partner or other persons from and against all claims and demands whatsoever.

Under the terms of the Registrant’s First Amended and Restated Agreement of Limited Partnership (the “Partnership Agreement”) the Registrant will indemnify and hold harmless the following persons, in most circumstances, to the fullest extent permitted by law, from and against all losses, claims, damages, liabilities (joint or several) expenses (including legal fees and expenses), judgments, fines, penalties, interest, settlements or other amounts arising from any and all threatened, pending or completed claims, demands, actions, suits or proceedings, whether civil, criminal, administrative or investigative, and whether formal or informal and including appeals:

(1) the General Partner, as the general partner of the Registrant;

(2) any departing general partner of the Registrant (a “Departing GP”);

(3) any person who is or was an affiliate of the General Partner or any Departing GP;

(4) any person who is or was a manager, managing member, general partner, director, officer, fiduciary or trustee of the Registrant, its subsidiaries, the General Partner, any Departing GP or any of their respective affiliates;

(5) any person who is or was serving as an officer, director, manager, managing member, general partner, employee, agent, fiduciary or trustee of another person owing a fiduciary duty to the Registrant or its subsidiaries;

(6) any person who controls the General Partner or any Departing GP; or

(7) any person designated by the General Partner.

Any indemnification under these provisions will only be out the assets of the Registrant. Unless the General Partner agrees otherwise, it will not be personally liable for, or have any obligation to contribute or loan any monies or property to the Registrant to enable it to effectuate, indemnification. The Registrant may purchase and maintain (or reimburse the General Partner or its affiliates for the cost of) insurance, on behalf of the General Partner, its affiliates and such other persons as the General Partner determines, covering liabilities that may be asserted against, or expense that may be incurred by such persons for the Registrant’s activities or such person’s activities on behalf of the Registrant, regardless of whether the Registrant would have the power to indemnify such person against such liabilities under the Partnership Agreement.

Subject to any terms, conditions or restrictions set forth in the applicable limited liability company agreement, Section 18-108 of the Delaware Limited Liability Company Act provides that a Delaware limited liability company may indemnify and hold harmless any member or manager or other person from and against any and all claims and demands whatsoever. The General Partner may enter into indemnity agreements with each of its current directors and officers to give such persons additional contractual assurances regarding the scope of the indemnification set forth in General Partner’s limited liability company agreement and to provide additional procedural protections.

The underwriting agreement that the Registrant entered into on July 29, 2014 contains indemnification and contribution provisions.

3

The Plan provides that the committee that administers the Plan (the “Committee”) and all members thereof are entitled to, in good faith, rely or act upon any report or other information furnished to them by any officer or employee of the Registrant, the General Partner, any of their affiliates, the Registrant’s or General Partner’s legal counsel, independent auditors, consultants or any other agents assisting in the administration of this Plan. Members of the Committee and any officer or employee of the General Partner, the Registrant, or any of their affiliates acting at the direction or on behalf of the Committee shall not be personally liable for any action or determination taken or made in good faith with respect to the Plan, and shall, to the fullest extent permitted by law, be indemnified and held harmless by the Registrant with respect to any such action or determination.

Item 9. Undertakings.

(a) The undersigned Registrant hereby undertakes:

(1) To file, during any period in which offers or sales are being made, a post-effective amendment to this Registration Statement:

(i) To include any prospectus required by Section 10(a)(3) of the Securities Act;

(ii) To reflect in the prospectus any facts or events arising after the effective date of the Registration Statement (or the most recent post-effective amendment thereof) which, individually or in the aggregate, represent a fundamental change in the information set forth in the Registration Statement. Notwithstanding

4

the foregoing, any increase or decrease in volume of securities offered (if the total dollar value of securities offered would not exceed that which was registered) and any deviation from the low or high end of the estimated maximum offering range may be reflected in the form of a prospectus filed with the Commission pursuant to Rule 424(b) if, in the aggregate, the changes in volume and price represent no more than a 20% change in the maximum aggregate offering price set forth in the “Calculation of Registration Fee” table in the effective registration statement; and

(iii) to include any material information with respect to the plan of distribution not previously disclosed in the Registration Statement or any material change to such information into the Registration Statement;

provided, however, that paragraphs (i) and (ii) do not apply if the information required to be included in a post-effective amendment by those paragraphs is contained in periodic reports filed with or furnished to the Commission by the Registrant pursuant to Section 13 or Section 15(d) of the Exchange Act that are incorporated by reference in this Registration Statement.

(2) That, for the purpose of determining any liability under the Securities Act, each such post-effective amendment shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

(3) To remove from registration by means of a post-effective amendment any of the securities being registered which remain unsold at the termination of the offering.

(b) The undersigned Registrant hereby undertakes that, for purposes of determining any liability under the Securities Act, each filing of the Registrant’s annual report pursuant to Section 13(a) or Section 15(d) of the Exchange Act (and, where applicable, each filing of an employee benefit plan’s annual report pursuant to Section 15(d) of the Exchange Act) that is incorporated by reference in the Registration Statement shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

(c) Insofar as indemnification for liabilities arising under the Securities Act may be permitted to directors, officers and controlling persons of the Registrant pursuant to the foregoing provisions, or otherwise, the Registrant has been advised that in the opinion of the Commission such indemnification is against public policy as expressed in the Securities Act and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the Registrant of expenses incurred or paid by a director, officer or controlling person of the Registrant in the successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered, the Registrant will, unless, in the opinion of its counsel, the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Securities Act and will be governed by the final adjudication of such issue.
