            RE:       Registration Statement on Form S-3
                      File No.: 8107.11
  Gentlemen:

            This opinion is being furnished in connection with the
  Registration Statement on Form S-3 (the"Registration Statement") of
  Digital Fusion, Inc. (the "Company") under the Securities Act of
  1933, as amended (the "Act"), for the registration of 1,026,153
  shares of common stock, par value $.01 (the "Shares"). As counsel for
  the Company, we have examined and are familiar with the Articles of
  Incorporation and Bylaws of the Company; the proceedings of the Board
  of Directors of the Company relating to the issuance of the Shares;
  and such other Company records, documents and matters of law as we
  have deemed to be pertinent. Based upon our examination of such
  documents and our familiarity with such proceedings, it is our
  opinion that:

            1. The Company has been duly incorporated and its status is
  active under the laws of the State of Delaware.

            2. The Shares, when issued, shall be duly authorized, fully
  paid and nonassessable. We hereby consent to the inclusion of this
  opinion as Exhibit 5 in the Registration Statement and to the
  reference to this firm under the caption "Legal Matters" in the
  prospectus. In giving this consent, we do not thereby admit that we
  come within the category of persons whose consent is required under
  Section 7 of the Act or the rules or regulations of the Securities
  and Exchange Commission promulgated thereunder.
