                          [DIMENSION DATA LETTERHEAD]


May 6, 2001



Mr. Raul J. Fernandez
Chairman of the Board
and Chief Executive Officer
Proxicom, Inc.
11600 Sunrise Valley Drive
Reston, Virginia  20191

Dear Raul

As I am sure you can understand, we were extremely surprised when Proxicom
announced its merger agreement with Compaq Computer Corporation. In light of our
discussions in Washington, D.C. as recently as April 25th with respect to our
proposed acquisition of Proxicom, we were disappointed that you did not give
Dimension Data the opportunity to make a superior offer before proceeding with
the transaction with Compaq.

We continue to believe that a Dimension Data-Proxicom combination makes
compelling business sense and provides a unique opportunity for your
shareholders to realize maximum value for their shares. Such a combination would
also be in the long-term interest of your employees who will have an opportunity
to play a central role in the establishment of a new category of systems
integrator. We are extremely impressed with the business you and your management
team have developed and excited about the manner in which it complements our
businesses. We believe that there are clear and convincing advantages to both
Proxicom and Dimension Data as the combination of our two companies pairs one of
the most respected e-business integrators with a unique global infrastructure
services company, resulting in a differentiated merger that will be exciting to
management, shareholders and especially employees. In addition, a business
combination between Proxicom and Dimension Data would benefit both Proxicom's
and Dimension Data's customers. Due to the independence of the companies, we
will be retaining the ability to offer customers the best solution, a principle
that has always been a foundation of Proxicom's success.

Therefore, we are offering to acquire all of Proxicom's outstanding common stock
at a price of $7.50 per share in cash. This offer represents a 30% premium over
the proposed Compaq transaction. The transaction would be structured as a tender
offer to all of your shareholders followed by a back-end merger at $7.50 per
share in cash.

Our Board has fully authorized this proposal, and we are prepared to execute the
form of Agreement and Plan of Merger attached hereto, which is substantially
identical to the agreement you have executed with Compaq. We will require
support agreements from you and the General Atlantic Partners entities which are
identical to those executed with Compaq. As is the case in the Compaq
transaction, we also will require that retention agreements be entered into with
the nine key executives of Proxicom, including you, and that you separately
enter into an arrangement locking up a portion of your proceeds from the
transaction. We have attached forms of these documents which reflect our
discussions on these matters just prior to the announcement of the Compaq
transaction and, therefore, we believe that we can execute these agreements
expeditiously as well. Our proposal is not subject to any financing contingency.
Our proposal is only subject to customary conditions, including the execution of
definitive agreements.

As you know, it is necessary to make our superior proposal in this manner
because of the "no shop" provisions of your merger agreement with Compaq.
However, we would prefer to work together with you and your Board of Directors
in completing a negotiated transaction. To that end, we are prepared to commit
all necessary resources to work with you in promptly completing a transaction.
We and our advisors are ready to meet with you and your advisors to discuss all
aspects of our offer, and to answer any questions you or they may have about our
offer.


Our objective is to promptly conclude a transaction that is enthusiastically
supported by you and your Board of Directors, shareholders and employees. We
look forward to hearing from you.


Yours sincerely,

/s/ Jeremy Ord

PRESS RELEASE
Monday, 7  May, 2001

                DIMENSION DATA MAKES COUNTER OFFER FOR PROXICOM

London, May 7, 2001 - Dimension Data Holdings plc today announced that it had
tabled a competing offer to acquire all the shares of Proxicom, Inc. at $7.50
per share, a 30% premium to the offer made by Compaq Computer Corporation on 26
April 2001. The offer values Proxicom equity at $ 448 million or a transaction
value of $ 376 million taking into account cash on the balance sheet of $72
million.

Dimension Data has conducted a thorough analysis of the US e-business industry
and a detailed due diligence review of Proxicom. Dimension Data believes that
Proxicom is an ideal fit to enhance its e-business integration model, which
combines the integration skills of both network infrastructure and application
software. The successful acquisition and integration of Proxicom would place
Dimension Data in a leading position to address the emerging requirement for
integrated networking and software solutions.

The acquisition would:
 . enhance Dimension Data's networking and managed services offering with e-
  business strategy, consulting, integration and strong technical skills,
 . provide strong expertise in key vertical industries,
 . strengthen the group's global scale and reach,
 . accelerate the visibility of the Dimension Data brand, particularly in the US
  market,
 . enable Dimension Data to gain size and scale and enhance its competitive
  position in a rapidly consolidating environment, and
 . enhance the Group's ability to attract and retain the best skills in the
  industry through the establishment of a new category systems integration
  company with a strong US presence.

In accordance with the Compaq merger agreement, Proxicom notified Compaq of its
receipt of the Dimension Data proposal, and the Proxicom Board of Directors
authorized the company's management and advisors to enter into negotiations with
Dimension Data. Under the terms of the Compaq merger agreement, should Proxicom
determine that the Dimension Data offer is a superior proposal and determine to
enter into a definitive transaction agreement with Dimension Data, Proxicom must
notify Compaq and Compaq would have three business days to determine whether to
match Dimension Data's offer. There can be no assurance as to the outcome of
this process.

Dimension Data is being advised by Merrill Lynch & Co. and Deutsche Bank in this
transaction.
