Explanatory Note

American Realty Capital Properties, Inc. is filing this Post-Effective Amendment No. 1, or the Amendment, to the Registration Statement on Form S-3 (File No. 333-182971), or the Registration Statement, solely to amend Part II thereof to include certain items which were previously omitted inadvertently as a result of a typographical error. Other than the foregoing additions, there is no change to any information contained in the Registration Statement filed with the Securities and Exchange Commission, on August 15, 2012. Accordingly, this Amendment consists only of the facing page, this Explanatory Note, Part II of the Registration Statement and the signature pages to the Amendment. The prospectus is unchanged and has been omitted from this Amendment.

All amounts in the table above, except the SEC registration fee and the FINRA filing fee, are estimated. These amounts do not include expenses of preparing and printing any related prospectus supplements, listing fees, trustee fees and expenses, transfer agent fees and other expenses related to offerings of particular securities from time to time. Estimated fees and expenses associated with future offerings will be provided in the applicable prospectus supplement.

Item 15. Indemnification of directors and officers

Maryland law permits a Maryland corporation to include in its charter a provision limiting the liability of its directors and officers to the corporation and its stockholders for money damages except for liability resulting from (1) actual receipt of an improper benefit or profit in money, property or services or (2) active and deliberate dishonesty established by a final judgment as being material to the cause of action. Our charter contains such a provision and limits the liability of our directors and officers to the maximum extent permitted by Maryland law.

Our charter obligates us, to the maximum extent permitted by Maryland law, to indemnify and, without requiring a preliminary determination of the ultimate entitlement to indemnification, pay or reimburse reasonable expenses in advance of final disposition of a proceeding to (1) any present or former director or officer of our company who is made or threatened to be made a party to the proceeding by reason of his service in that capacity or (2) any individual who, while serving as our director or officer and at our request, serves or has served another corporation, real estate investment trust, partnership, limited liability company, joint venture, trust, employee benefit plan or any other enterprise as a director, officer, partner, member, manager or trustee of such corporation, real estate investment trust, partnership, limited liability company, joint venture, trust, employee benefit plan or other enterprise, and who is made or threatened to be made a party to the proceeding by reason of his service in that capacity. Our charter also permits us to indemnify and advance expenses to any person who served any predecessor of our company in any of the capacities described above and to any employee or agent of our company or of any predecessor.

The MGCL requires us (unless our charter provides otherwise, which our charter does not) to indemnify a director or officer who has been successful, on the merits or otherwise, in the defense of any proceeding to which he is made or threatened to be made a party by reason of his service in that capacity. The MGCL permits a corporation to indemnify its present and former directors and officers, among others, against judgments, penalties, fines, settlements and reasonable expenses actually incurred by them in connection with any proceeding to which they may be made or threatened to be made a party by reason of their service in those or other capacities unless it is established that (1) the act or omission of the director or officer was material to the matter giving rise to the proceeding and (A) was committed in bad faith or (B) was the result of active and deliberate dishonesty, (2) the director or officer actually received an improper personal benefit in money, property or services, or (3) in the case of any criminal proceeding, the director or officer had reasonable cause to believe that the act or omission was unlawful. However, under the MGCL, a Maryland corporation may not indemnify a director or officer for an adverse judgment in a suit by or in the right of the corporation or for a judgment of liability on the basis that a personal benefit was improperly received. A court may order indemnification if it determines that the director or officer is fairly and reasonably entitled to indemnification, even though the director or officer did not meet the prescribed standard of conduct or was adjudged liable on the basis that personal benefit was improperly received. However, indemnification for an adverse judgment in a suit by us or in our right, or for a judgment of liability on the basis that personal benefit was improperly received, is limited to expenses. In addition, the MGCL permits a corporation to advance reasonable expenses to a director or officer upon the corporation’s receipt of (1) a written affirmation by the director or officer of his good faith belief that he has met the standard of conduct necessary for indemnification by the corporation and (2) a written undertaking by him or on his behalf to repay the amount paid or reimbursed by the corporation if it is ultimately determined that the appropriate standard of conduct was not met.

We also are party to indemnification agreements with each of our directors and executive officers that provide for indemnification to the maximum extent permitted by Maryland law.

Insofar as indemnification for liabilities arising under the Securities Act may be permitted to directors, officers or persons controlling us pursuant to the foregoing provisions, we have been informed that, in the opinion of the SEC, such indemnification is against public policy as expressed in the Securities Act and is, therefore, unenforceable.
