PART III
NARRATIVE

State below in reasonable detail why the Form 10-K, 11-K, 20-F 10-Q, N-SAR or the transition report portion thereof could not be filed within the prescribed time period. (Attach extra sheets if needed.)

On November 14, 2000, ICG Communications, Inc. (the "Company") and most of its subsidiaries (except for certain non-operating entities) filed voluntary petitions for protection under Chapter 11 of the United States Bankruptcy Code in the Federal Court for the District of Delaware (the "Bankruptcy Court").  On July 26, 2002, the Company filed in the Bankruptcy Court a proposed modified plan of reorganization (the "Modified Plan") and a supplement to its previously filed disclosure statement.  On October 10, 2002, the "Effective Date", the Company's Modified Plan became effective and the Company emerged from Chapter 11 bankruptcy protection.  All of the Company's pre-petition publicly traded debt and equity securities were cancelled in accordance with the Modified Plan.  Distribution of the new common shares is to take place on a date that has not yet been determined, but is expected to occur no later than December 31, 2002.  These events are described more fully in the Company's Form 8-K dated October 9, 2002.

As required by the Modified Plan, on the Effective Date all members of the Company's Board of Directors resigned and new members were appointed.  The new Board of Directors has not yet had an opportunity to meet formally with the Company's management, appoint an Audit Committee, or review the information included in the Company's Form 10-Q for the quarterly period ended September 30, 2002 (the "Form 10-Q").  Management has determined that it would be appropriate and prudent to give the Board of Directors additional time to do so before filing the Form 10-Q.  The Board of Directors has been consulted on this matter and agrees with management's decision to delay the filing of the Form 10-Q.

The first Board of Directors meeting is scheduled for early December 2002.  Management expects to file the Form 10-Q on or before December 15, 2002.
