Pursuant to the Sales Agency Financing Agreements

Ladies and Gentlemen:

We have acted as counsel for SITE Centers Corp., an Ohio corporation (the “Company”), in connection with the issuance and sale of up to $250,000,000 aggregate offering price of common shares, $0.10 par value per share, of the Company (the “Shares”) pursuant to the Sales Agency Financing Agreements listed on Schedule I attached hereto (the “Sales Agency Financing Agreements”) and the Master Confirmations for Forward Stock Sale Transactions listed on Schedule II attached hereto. The Shares may be offered and sold from time to time pursuant to Rule 415 under the Securities Act of 1933 (the “Act”) in accordance with the terms of the Sales Agency Financing Agreements.

In connection with the opinion expressed herein, we have examined such documents, records and matters of law as we have deemed relevant or necessary for purposes of this opinion. Based upon the foregoing and subject to the further assumptions, qualifications and limitations set forth herein, we are of the opinion that the Shares, when issued and delivered pursuant to the terms of the Sales Agency Financing Agreements against payment of the consideration therefor as provided therein, will be validly issued, fully paid, and nonassessable; provided that such consideration is at least equal to the stated par value of the Shares.

In rendering the opinion above, we have assumed that (i) the resolutions authorizing the Company to issue and deliver and sell the Shares pursuant to the Sales Agency Financing Agreements will be in full force and effect at all times at which the Shares are issued and delivered or sold by the Company and the Company will take no action inconsistent with such resolutions, and (ii) the timing of, the terms of and the consideration for each issuance of Shares by the Company under the Sales Agency Financing Agreements will be approved by the Board of Directors of the Company or an authorized committee or subcommittee of the Board of Directors.
