             COLT Telecom Group plc Initiates Consent Solicitation

                     2.0% Notes due 2007 (the "2007 Notes")
                    7.625% Notes due 2008 (the "2008 Notes")
                    7.625% Notes due 2009 (the "2009 Notes")
                            (together, the "Notes")

This announcement is not to be forwarded or distributed to any person located or
resident in Italy.

COLT Telecom Group plc, a public limited company incorporated under the laws of
England and Wales ("COLT"), announces that it is soliciting (the "Solicitation")
consents (the "Consents") from Holders (as defined in the indentures governing
its Notes (the "Indentures")) to amendments (the "Proposed Amendments") to the
Indentures that will amend COLT's reporting obligations under the Indentures and
eliminate the obligation to deliver annually a written statement from its
independent public accountants with respect to COLT's compliance with the
Indentures.

The Proposed Amendments to COLT's reporting obligations would remove the
requirement in the Indentures that COLT file periodic reports with the SEC under
the Exchange Act. This will facilitate COLT's ability, if it considers it
appropriate to do so, to terminate the listing of its ordinary shares and
American Depositary Receipts ("ADRs") on NASDAQ and suspend or terminate
(subject to SEC rulemaking) its reporting obligations under the Exchange Act.
The principal trading markets for COLT's ordinary shares are in London and there
is very little trading in ADRs on NASDAQ. In addition, COLT's reporting
obligations under the Exchange Act cause COLT to incur substantial costs. Under
the Proposed Amendments, COLT will continue to be obligated to provide Holders
with annual, quarterly and event-based reports but will not be required under
the terms of the Indentures as amended to file those reports with the SEC. These
reports will be prepared in accordance with International Financial Reporting
Standards as in effect in the United Kingdom, in line with COLT's legal
obligations. In addition, Holders will continue to have access to other
information regarding COLT that it prepares for its public security holders
generally. COLT also currently intends to continue its existing practice of
holding conference calls following the disclosure of its annual and quarterly
financial information to discuss that information and the results of its
operations for the relevant reporting period.

The Board of Directors of COLT has not taken a final decision to proceed with
de-listing its shares from NASDAQ and de-registration from SEC reporting
requirements. No assurance can be given that COLT will de-list or de-register.
If COLT does not de-list and de-register, it will continue to file reports with
the SEC as required by the Exchange Act. This will not affect COLT's current
listing of its debt and ordinary shares in London.

The Proposed Amendments would also remove the requirement to provide a written
statement from COLT's independent public accountants to the Trustee on an annual
basis concerning compliance with the provisions of the Indentures. This is
because the circumstances in which firms of accountants in the United Kingdom
are prepared to provide this type of statement are very limited and COLT's
independent public accountants have informed COLT that, as a matter of practice,
they do not provide such certification. COLT is also seeking a waiver of all
failures to comply with this requirement.

The Solicitation is made upon the terms and is subject to the conditions set
forth in the Consent Solicitation Statement dated February 3, 2006, and any
amendments or supplements thereto (the "Statement").

Subject to the conditions set forth in the Statement being satisfied, the
Proposed Amendments will be effected by a supplemental indenture to each of the
Indentures (the "Supplemental Indentures"), which is to be executed, in each
case, by COLT and the Trustee upon receipt of the Consents of Holders of a
majority in principal amount outstanding of each series of Notes.

Subject to the conditions set forth in the Statement  being  satisfied or waived
and the  Supplemental  Indentures being entered into, COLT shall pay each Holder
subject to the  Supplemental  Indentures  who  delivered  a valid  Consent  (not
subsequently  revoked)  on or before  the  Expiration  Date a consent  fee.  The
consent fee will equal EUR2.00 per EUR1,000  principal amount of 2007 Notes held
by a  Holder  with  respect  to which a valid  Consent  was  delivered  (and not
revoked),  EUR1.02 per DM1,000  principal  amount of 2008 Notes  (equivalent  of
EUR2.00 per EUR1,000  principal amount) held by a Holder with respect to which a
valid Consent was delivered (and not revoked) and EUR2.00 per EUR1,000 principal
amount of 2009 Notes held by a Holder in  respect of which a valid  Consent  was
delivered (and not revoked).

NONE OF COLT, THE SOLICITATION AGENT, THE TABULATION AGENT OR THE INFORMATION
AGENT (EACH AS DEFINED BELOW) MAKES ANY RECOMMENDATION AS TO WHETHER OR NOT
HOLDERS SHOULD DELIVER CONSENTS TO THE PROPOSED AMENDMENTS AND WAIVER. OTHER
THAN AS CONTAINED IN THE STATEMENT, NO PERSON HAS BEEN AUTHORISED TO MAKE ANY
RECOMMENDATION AS TO WHETHER HOLDERS SHOULD DELIVER CONSENTS.

   Important information for United Kingdom recipients of this announcement:

Please note that this announcement is not an invitation to deliver Consents.
Rather, Holders should receive and consider the Statement. Holders should seek
advice from an independent financial advisor as to whether they should deliver
Consents.

The Solicitation is made upon, and is subject to, the detailed terms and
conditions set forth in the Statement which can be inspected free of charge at
the offices of the information agent, Bondholder Communications Group (the
"Information Agent"), at 28 Throgmorton Street, London, EC2N 2AN, United Kingdom
and at the offices of the tabulation agent, The Bank of New York (the
"Tabulation Agent") at One Canada Square, London, E14 5AL, United Kingdom. The
Statement can also be obtained from the website of the Information Agent at

London Branch, in its capacity as the sole solicitation agent on this
Solicitation, attention: Liability Management Group, at +44 207 545 8011.
