Gentlemen:

You have requested my opinion, as counsel for LCI International, Inc. and/or
its subsidiaries (the "Company"), in connection with the Registration Statement
on Form S-8 to be filed by the Company with the Securities and Exchange
Commission (the "Registration Statement") in connection with the registration
under the Securities Act of 1933, as amended, by the Company of 3,000,000
shares of Common Stock, par value $.01 per share (the "Common Stock"), which
shares are issuable upon exercise of stock options granted or to be granted
under the 1997/1998 LCI International, Inc. Stock Option Plan ("the Plan").

I have examined and relied upon originals or copies, certified, or otherwise
identified to my satisfaction, of such documents, corporate records,
certificates and instruments relating to the Company as I have deemed relevant
and necessary to the information of the opinion hereinafter set forth.  In such
examination, I have assumed the genuineness and authenticity of all documents
examined by me and all signatures thereon, the legal capacity of all persons
executing such documents, the conformity to originals of all copies of
documents submitted to me and the truth and correctness of any representations
and warranties contained therein.

Based upon and subject to the foregoing and to such further limitations and
qualifications as set forth below, we are of the opinion that:

         The Common Stock, when issued in accordance with the
         terms of the Plan, will be legally issued, fully paid
         and non-assessable.

I hereby consent to the filing of this opinion as an exhibit to the
Registration Statement.

Sincerely,

/s/ Lee. M. Weiner
