EXPLANATORY NOTE

This Amendment No. 1 (this Amendment) to our Quarterly Report on Form 10-Q for the quarterly period ended September 30,
2013 filed with the Securities and Exchange Commission on November 7, 2013 (the Original Filing) is filed to disclose information in connection with Section 219 of the Iran Threat Reduction and Syria Human Rights Act of 2012.
Other than this additional compliance disclosure in Part II. Item 5. Other Information and the additional exhibits in Part II. Item 6. Exhibits, no part of the Original Filing is amended hereby, and this Amendment
does not reflect events that occurred after the date of the Original Filing.

PART II. OTHER INFORMATION

Item 5.Other Information.

Under Section 13(r) of the Securities Exchange Act of 1934, as amended by the Iran Threat Reduction and Syria Human Rights Act of 2012,
issuers are required to include certain disclosures in their periodic reports if they or any of their affiliates (as defined in Rule 12b-2 thereunder) have knowingly engaged in certain specified activities relating to Iran. Disclosure is
required even where the activities are conducted outside the United States by non-U.S. affiliates in compliance with applicable law, and even if the activities are not covered or prohibited by U.S. law.

Oiltanking GmbH, the ultimate parent company of our general partner, maintains a joint venture interest in Oiltanking Odfjell GmbH, which in
turn owns a joint venture interest in the Exir Chemical Terminal (ECT) in Iran. This interest results from an investment dating back to 2002. Oiltanking GmbH currently has the contractual right to vote for the appointment of one member
of ECTs three-member board. Oiltanking GmbH provides no goods, services, technology, information or support to ECT and plays no role in the management or day-to-day operations of ECT.

Among other activities, ECT transfers naptha originating in Iraq to Oman for a customer in the United Arab Emirates, and it does not import or
handle any Iranian-origin products that are regulated under U.S., European Union or United Nations sanctions laws. ECT pays routine and standard charges (i) to the Petrochemical Special Economic Zone Organization (Petzone) for the
use of pipelines and (ii) to Terminals and Tanks Petrochemical Co. (TTPC), which operates the berth. Petzone and TTPC are subsidiaries of the National Petrochemical Company, which is owned and controlled by the Government of Iran.
As Oiltanking GmbH has no direct involvement in the day to day operations of ECT, we have no information regarding ECTs intent to continue or not continue making the payments described above

Oiltanking GmbH maintains an internal compliance program to ensure compliance with all applicable sanctions regimes, including sanctions laws
maintained by the United States, European Union and United Nations. Although the existence of the routine payments described above may be reportable under Section 13(r), Oiltanking GmbH has informed us that neither it, nor any of its
subsidiaries or affiliates, has engaged in any conduct that would be sanctionable under any of these legal regimes.

Item 6.Exhibits

Item 6 of the Original Filing is amended by the addition of the following exhibits:
