          Registration Statement on Form S-3

Ladies and Gentlemen:

     We have acted as counsel to Concurrent Computer Corporation, a Delaware
corporation (the "Company"), in connection with the registration of 291,461
shares of common stock (the "Shares"), as described in the Company's
Registration Statement on Form S-3 (the "Registration Statement"), filed with
the Securities and Exchange Commission under the Securities Act of 1933, as
amended.  The Shares were issued to the selling stockholder in connection with
the Share Purchase and Warrant Issuance Agreement between the Company and
Thirdspace Living Limited, dated March 19, 2002 (the "Agreement").

     As such counsel, we have examined and relied upon such records, documents,
certificates and other instruments as in our judgment are necessary or
appropriate to form the basis for the opinions hereinafter set forth. In all
such examinations, we have assumed the genuineness of signatures on original
documents and the conformity to such original documents of all copies submitted
to us as certified, conformed or photographic copies, and as to certificates of
public officials, we have assumed the same to have been properly given and to be
accurate. As to matters of fact material to this opinion, we have relied upon
statements and representations of representatives of the Company and public
officials.

     The opinions expressed herein are limited in all respects to the corporate
law of the State of Delaware (which includes the Delaware General Corporation
Law, applicable provisions of the Delaware Constitution and reported judicial
decisions concerning those laws), and no opinion is expressed with respect to
the laws of any other jurisdiction or any effect which such laws may have on the
opinions expressed herein. This opinion is limited to the matters stated herein,
and no opinion is implied or may be inferred beyond the matters expressly stated
herein.

     Based upon the foregoing and subject to the other limitations and
qualifications set forth herein, we are of the opinion that:

     (i) The Company is a corporation validly existing and in good standing
under the laws of the State of Delaware; and

     (ii) The Shares issued to the selling stockholder have been duly authorized
and are validly issued, fully paid and nonassessable.


     This opinion is given as of the date hereof and we assume no obligation to
advise you after the effective date of the Registration Statement of facts or
circumstances that come to our attention or changes in law that occur which
could affect the opinions contained herein. This letter is being rendered solely
for the benefit of the Company in connection with the matters addressed herein.
This opinion may not be furnished to or relied upon by any person or entity for
any purpose without our prior written consent.

     We consent to the filing of this opinion as an exhibit to the Registration
Statement and to the reference to this firm under the caption "Legal Matters" in
the prospectus which is part of the Registration Statement.

                                Very truly yours,

                                /s/ King & Spalding

                                KING & SPALDING
