Ladies and Gentlemen:

        We have acted as securities counsel for Sinclair Broadcast Group, Inc., a Maryland corporation (the "Company"), in connection with its filing on the date hereof with the Securities and Exchange Commission (the "Commission") of a Registration Statement on Form S-3 (the "Registration Statement"), under the Securities Act of 1933, as amended, with respect to the offering and issuance from time to time by the Company of up to $350,000,000 aggregate initial offering price of (1) one or more series of the Company's debt securities, which may be senior or subordinated (the "Debt Securities"), (2) shares of the Company's preferred stock, par value $0.01 per share (the "Preferred Stock"), (3) shares of the Company's Class A common stock, par value $0.01 per share (the "Common Stock"), or (4) depositary shares of the Company representing a fractional interest in a share of Preferred Stock ("Depositary Shares"). The Debt Securities, Preferred Stock, Common Stock, and Depositary Shares are collectively referred to herein as the "Securities". The terms used herein, unless otherwise defined, have the meanings assigned to them in the Registration Statement.

        We have examined originals, photocopies or conformed copies of all such records of the Company and its subsidiaries, all such agreements and certificates of public officials, and such other documents as we have deemed relevant and necessary as a basis for the opinion hereinafter expressed, including without limitation:

(1)

the Company's bylaws and articles of incorporation (the "Charter Documents");



(2)

the indenture for senior debt securities to be entered into between the Company and the trustee, in the form included as an exhibit to the Registration Statement (the "Senior Indenture"); and



(3)

the indenture for subordinated debt securities to be entered into between the Company and the trustee, in the form included as an exhibit to the Registration Statement (the "Subordinated Indenture").

As to any facts material to our opinion, we have made no independent investigation of such facts and have relied, to the extent that we deem such reliance proper, upon certificates of public officials and officers or other representatives of the Company.

        In rendering the opinions set forth below, we have assumed that (i) all signatures on all documents examined by us are genuine; (ii) all documents submitted to us as originals are authentic and all documents submitted to us as copies conform to the originals of those documents; (iii) each natural person signing any document reviewed by us had the legal capacity to do so; (iv) each person signing in a representative capacity (other than on behalf of the Company) any document reviewed by us had authority to sign in such capacity; (v) a prospectus supplement will have been prepared and filed with the Commission describing the Securities offered thereby; (vi) all Securities will be issued and sold in compliance with applicable federal and state securities laws and in the manner stated in the Registration Statement and the applicable prospectus supplement; (vii) the Senior Indenture and the

Subordinated Indenture, together with any supplemental indenture relating to a series of Debt Securities to be issued under either of such indentures, will each be duly authorized, executed and delivered by the parties thereto in substantially the form reviewed by us; (viii) a definitive purchase, underwriting or similar agreement with respect to any Securities offered will have been duly authorized and validly executed and delivered by the Company and the other parties thereto; (ix) any Securities issuable upon conversion, exchange or exercise of any Security being offered will have been duly authorized, created and, if appropriate, reserved for issuance upon such conversion, exchange or exercise; and (x) with respect to shares of Common Stock or Preferred Stock offered, there will be sufficient shares of Common Stock or Preferred Stock authorized under the Company's Charter Documents and not otherwise reserved for issuance.

Based upon and subject to the foregoing, we are of the opinion that:

        2.    With respect to shares of Common Stock, when (i) the Board has taken all necessary corporate action to approve the issuance and terms of the offering thereof and related matters; and (ii) certificates representing the shares of Common Stock have been duly executed, countersigned, registered and delivered either (a) in accordance with the applicable definitive purchase, underwriting or similar agreement approved by the Board upon payment of the consideration therefor (not less than the par value of the Common Stock) provided for therein, or (b) upon conversion, exchange or exercise of any other Security in accordance with the terms of the Security or the instrument governing the Security providing for the conversion, exchange or exercise as approved by the Board, for the consideration approved by the Board (not less than the par value of the Common Stock), the shares of Common Stock will be legally issued, fully paid and non-assessable.

        The foregoing opinions are qualified to the extent that the enforceability of any document, instrument or Security may be limited by or subject to (i) bankruptcy, insolvency, fraudulent transfer or conveyance, reorganization, moratorium or other similar laws relating to or affecting creditors' rights generally, and general equitable or public policy principles, and (ii) with respect to any Debt Securities denominated in a currency other than United States dollars, the requirement that a claim (or a foreign currency judgment in respect of such a claim) with respect to such Securities be converted to United States dollars at a rate of exchange prevailing on a date determined pursuant to applicable law or governmental authority.

        We express no opinions concerning (i) the validity or enforceability of any provisions contained in the Senior Indenture or the Subordinated Indenture that purport to waive or not give effect to rights to notices, defenses, subrogation or other rights or benefits that cannot be effectively waived under applicable law or (ii) the enforceability of indemnification provisions to the extent they purport to relate to liabilities resulting from or based upon negligence or any violation of federal or state securities or blue sky laws.

Our opinions are based on statutory and judicial decisions in effect at the date hereof, and we do not opine with respect to any law, regulation, rule or governmental policy or decision which may be enacted, determined or adopted after the date hereof, nor assume any responsibility to advise you of future changes in our opinions.

        We hereby consent to the filing of this opinion as an exhibit to the Registration Statement and to the statements made with respect to us under the caption "Legal Matters" in the prospectus included as part of the Registration Statement.
