                                EXPLANATORY NOTE

     This Amendment No. 1 on Form 10-Q/A to the Quarterly Report on Form 10-Q
for the period ended December 31, 2004 of Concurrent Computer Corporation (the
"Company"), initially filed with the Securities and Exchange Commission (the
"SEC") on February 4, 2005, is being filed to report information previously
omitted from Part II-Item 5 and to amend Part II-Item 6.  On October 25, 2004,
the Company granted performance based restricted shares to certain employees and
former employees of the Company.  A Form 8-K reporting the grants was filed on
March 3, 2005.  The amendments include information with respect to the grants
that was previously disclosed in the Form 8-K.  No other modifications to the
original Form 10-Q are being made with this amendment; therefore, this amendment
only contains Part II, Items 5 and 6 and new certifications of the Chief
Executive Officer and Chief Financial Officer of the Company required by Rule
12b-15 under the Securities Exchange Act of 1934, as amended.

PART  II   OTHER  INFORMATION

ITEM 5.     OTHER INFORMATION.

     On October 25, 2004 the Compensation Committee of the Board of Directors
granted performance based restricted shares to T. Gary Trimm, Warren Neuburger,
Steven K. Necessary*, Steven R. Norton*, Kirk L. Somers, Gregory S. Wilson, and
other employees of the Company pursuant to the Company's 2001 Stock Option Plan.
The number of performance based restricted shares granted are as follows:  T.
Gary Trimm, 63,047 shares; Warren Neuburger, 29,182 shares; Steven K. Necessary,
30,803 shares; Steven R. Norton, 27,020 shares; Kirk L. Somers, 14,771 shares;
and Gregory S. Wilson, 5,629 shares.  The shares will vest when and if the
Company accomplishes yearly revenue and net operating income goals set by the
Compensation Committee on the date of the grant.  The shares are returned to the
Company if the individual is not employed by the Company if and when the
performance goals are achieved.  If the performance criteria are not met within
any one year, they can be made up in the next fiscal year if the sum of the
actual results for the two year period exceeds the sum of the performance
criteria for that two year period.


*Subsequent to the stock grants, Messrs. Necessary and Norton ceased to be
employed by the Company.  In accordance with the vesting terms of such grants,
Messrs. Necessary and Norton forfeited all such grants of restricted shares.
