On December 16, 2015, Global Net Lease, Inc. (the “Company”) entered into an indemnification agreement (the “Indemnification Agreement”) with Timothy Salvemini (the “Indemnitee”) in connection with Mr. Salvemini’s appointment as chief financial officer, treasurer and secretary of the Company on December 1, 2015, as previously disclosed in the Current Report on Form 8-K filed by the Company on November 19, 2015. The Indemnification Agreement is substantially identical to the indemnification agreement entered into by the Company with its other directors and officers and provides that the Company will indemnify the Indemnitee, to the fullest extent permitted by Maryland law and the Company’s charter and subject to the limitations set forth in the Indemnification Agreement, from and against all judgments, penalties, fines and amounts paid in settlement and expenses actually and reasonably incurred by such Indemnitee that may result or arise in connection with the Indemnitee serving in his capacity as a present or former director, officer, employee or agent of the Company or as a director, trustee, officer, partner, manager, managing member, fiduciary, employee or agent of any other foreign or domestic corporation, partnership, limited liability company, joint venture, trust, employee benefit plan or other enterprise that such person is or was serving in such capacity at the request of the Company. The Indemnification Agreement further provides that, subject to the limitations set forth in the Indemnification Agreement, the Company will, without requiring a preliminary determination of the Indemnitee’s ultimate entitlement of indemnification under the Indemnification Agreement, advance all reasonable expenses to the Indemnitee incurred by or on behalf of the Indemnitee in connection with any proceeding the Indemnitee is or is threatened to be made a party to.

The Indemnification Agreement provides that the Indemnitee is entitled to indemnification unless it is established by clear and convincing evidence that (a) the act or omission of the Indemnitee was material to the matter giving rise to the proceeding and (i) was committed in bad faith or (ii) was the result of active and deliberate dishonesty, (b) the Indemnitee actually received an improper personal benefit in money, property or services or (c) in the case of any criminal proceeding, the Indemnitee had reasonable cause to believe that his or her conduct was unlawful. The Indemnification Agreement further limits the Indemnitee’s entitlement to indemnification in cases where (a) the proceeding was one by or in the right of the Company and the Indemnitee was adjudged, in a final adjudication of the Proceeding not subject to further appeal, to be liable to the Company, (b) the Indemnitee was adjudged, in a final adjudication of the Proceeding not subject to further appeal, to be liable on the basis that personal benefit was improperly received in any proceeding charging improper personal benefit to the Indemnitee or (c) the proceeding was brought by the Indemnitee, except in certain circumstances.

The Indemnification Agreement also provides that, except for a proceeding brought by the Indemnitee, the Company has the right to defend the Indemnitee in any proceeding which may give rise to indemnification under the Indemnification Agreement. The Indemnification Agreement grants the Indemnitee the right to separate counsel in certain proceedings involving separate defenses, counterclaims or other conflicts of interest and in proceedings in which the Company fails to assume the defense of the Indemnitee in a timely manner. The Indemnification Agreement further provides that the Company will use its reasonable best efforts to acquire directors and officers liability insurance covering the Indemnitee or any claim made against each Indemnitee by reason of his service to the Company.

The description of the Indemnification Agreement in this Current Report on Form 8-K is a summary and is qualified in its entirety by the full terms of the Indemnification Agreement. The Company will file the Indemnification Agreement with the Securities and Exchange Commission as an exhibit to its next Annual Report on Form 10-K.

On December 16, 2015, the Company’s board of directors appointed Scott J. Bowman, the Company’s chief executive officer, as president of the Company. Mr. Bowman will continue to serve as chief executive officer of the Company. There are no related party transactions involving Mr. Bowman that are reportable under Item 404(a) of Regulation S-K except as described in the Company’s annual proxy statement filed with the U.S. Securities and Exchange Commission on April 29, 2015.

Based on its assessment of investment opportunities in Europe, the Company’s advisor, Global Net Lease Advisors, LLC, has recommended, and the Company’s board of directors has approved, an amendment to the Company’s investment guidelines (the “Investment Guidelines”) to remove the limitation on investments in Europe. The Investment Guidelines had previously limited investments in Europe to 40% of the Company’s portfolio.
