This Amendment No. 2 to the Statement on Schedule 13D is being filed to report
the acquisition of 260 shares of Series M Preferred Stock which is convertible
into common stock, par value $0.001 per share (the "Common Stock") of Cogent

BNP Europe Telecom & Media Fund II, L.P., a limited partnership formed under the
laws of the Cayman Islands, British West Indies ("BNP ETMF"), General Business
Finance and Investments, Ltd., a company formed under the laws of the Cayman
Islands, British West Indies ("GBFI"), Natio Vie Developpement 3, Fonds Commun
de Placement a Risque, a limited partnership formed under the laws of France
("NVD3") and BNP Private Equity SA, a societe anonyme formed under the laws of
France ("BNP PE" and together with BNP ETMF, GBFI and NVD3, the "Reporting
Persons") with the Securities and Exchange Commission on August 5, 2004 (the
"Previous Filing"). Only those items that are hereby reported are amended; all
other items remain unchanged. All capitalized terms shall have the meanings
assigned to them in the Previous Filing, unless otherwise indicated herein.

ITEM 3.  SOURCE AND AMOUNT OF FUNDS OR OTHER CONSIDERATION

Item 3 is hereby amended and supplemented by the addition of the following
paragraphs:

As of October 26, 2004, BNP ETMF and NVD3 entered into an Agreement and Plan of
Merger by and among the Company, Cogent Potomac, Inc. and NVA Acquisition, Inc.
(the "NVA Agreement and Plan of Merger"). Such NVA Agreement and Plan of Merger
is attached hereto as Exhibit E. BNP ETMF and NVD3 each held shares of NVA
Acquisition, Inc. and were subsequently issued shares of the Company's Series M
Participating Convertible Preferred Stock, par value $0.001 per share (the
"Series M Preferred Stock") pursuant to the terms of the NVA Agreement and Plan
of Merger. Each share of the common stock of NVA Acquisition, Inc. held by the
Reporting Persons was exchanged for one (1) share of Series M Preferred Stock
pursuant to the NVA Agreement and Plan of Merger. The Series M Preferred Stock
is convertible at the earlier of January 31, 2005 or the date on which the
Company files an amendment to its Certificate of Incorporation pursuant to the
Certificate of Designations of its Series M Preferred Stock (the "Series M
Certificate of Designations" and together with the Series I Certificate of
Designations and the Series J Certificate of Designations, the "Certificates of
Designations") attached hereto as Exhibit F.

Through a conversion mechanism detailed in the NVA Agreement and Plan of Merger,
BNP ETMF obtained two hundred and ten (210) shares of Series M Preferred Stock
and NVD3 obtained fifty (50) shares of Series M Preferred Stock. Each share of
Series M Preferred Stock will be convertible into Common Stock at an initial
conversion price of $0.1613, or at an initial conversion rate of approximately
30,998.15 shares of Common Stock for each share of Series M Preferred Stock
converted, subject to antidilution adjustments (subject to certain exceptions)
and certain other adjustments as set forth in the Series M Certificate of
Designations.

This Item 3 (and the other Items of this statement) does not provide a complete
description of the NVA Agreement and Plan of Merger or the Series M Certificate
of Designations and each such description is qualified in its entirety by
reference to the respective agreement or document which the Reporting Persons
have filed as Exhibits E and F to this form.


                                       7

ITEM 4.  PURPOSE OF TRANSACTION

The last seven paragraphs contained in Item 4 are hereby deleted and replaced by
the following:

Series M Certificate of Designations

BNP ETMF and NVD3 entered into the NVA Agreement and Plan of Merger pursuant to
which the Company agreed to issue, and each of BNP ETMF and NVD3 agreed to
acquire, the number of shares of Series M Preferred Stock as described in Item 3
above. As a condition to the closings under the NVA Agreement and Plan of
Merger, the Company was obligated to file the Series M Certificate of
Designations, which provides that the Series M Preferred Stock has certain
"weighted average" antidilution protection with respect to the conversion price
of the Series M Preferred Stock and certain liquidation, conversion and voting
rights. Descriptions of such rights contained herein are qualified in their
entirety by reference to the Series M Certificate of Designations attached
hereto as Exhibit F.

Certificate of Designations - Conversion of Series M Preferred Stock. All of the
shares of Series M Preferred Stock shall be automatically converted into Common
Stock upon certain conditions described in the Series M Certificate of
Designations. The Series M Preferred Stock is convertible at the earlier of
January 31, 2005 and the date on which the Company files an amendment to its
Certificate of Incorporation pursuant to the Series M Certificate of
Designations.

Certificate of Designations - Dividends. In the event that any dividend or other
distribution payable in cash or other property is declared on the Common Stock
or any security that is pari passu or junior to the Series M Preferred Stock
(other than dividends payable solely in shares of Common Stock), the shares of
Series M Preferred Stock shall be entitled to receive an amount equal per share
(on an as-if-converted to Common Stock basis) to the amount paid or set aside
for each share of Common Stock or other security that is pari passu or junior to
the Series M Preferred Stock. As of the date hereof, there are no dividends
declared on the Series M Preferred Stock.

Certificate of Designations - Voting. As set forth in the Series M Certificate
of Designations, and except as otherwise provided by applicable law, the holders
of Series M Preferred Stock (i) shall be entitled to vote with the holders of
Common Stock on all matters submitted for a vote of holders of Common Stock and
(ii) shall be entitled to one vote for each share of Common Stock such holder of
Series M Preferred Stock would receive upon conversion of such share of Series M
Preferred Stock into Common Stock. For so long as 20% of the shares of Series M
Preferred Stock remain outstanding, the holders of 80% of the Series M Preferred
Stock must approve any public offering of the Company's stock, other than a
"Qualified Offering" as defined therein.

Certificate of Designations - Liquidation Preference. In the event of the
