The Shares are covered by the above-referenced Registration Statement, and all amendments thereto (the “Registration Statement”), filed by the Company with the United States Securities and Exchange Commission (the “Commission”) under the Securities Act of 1933, as amended (the “1933 Act”), and may be issued to the Selling Stockholders upon the redemption of units (the “Units”) of limited partnership interest of Global Net Lease Operating Partnership, L.P., a Delaware limited partnership, held by the Selling Stockholders.

In connection with our representation of the Company, and as a basis for the opinion hereinafter set forth, we have examined originals, or copies certified or otherwise identified to our satisfaction, of the following documents (hereinafter collectively referred to as the “Documents”):
