                              ANNUAL MEETING ALERT

                                                                  April 28, 2000

Dear Fellow Shareholder:

            DO NOT SIGN OR RETURN ANY BLUE PROXY CARD FROM VETROTEX
        PLEASE SIGN AND RETURN ONLY THE WHITE PROXY CARD FROM BRUNSWICK

     Vetrotex CertainTeed Corporation will soon be mailing proxy material to you
(with a blue proxy card) asking you to support its efforts at the Annual Meeting
of Stockholders. As I am sure you are aware, on April 20, 2000 Brunswick
received an unsolicited offer from Compaignie de Saint-Gobain -- a French
company -- to acquire all of Brunswick's shares. VETROTEX IS A SUBSIDIARY OF
SAINT-GOBAIN and we believe that Vetrotex is attempting to interfere with our
annual meeting solely in connection with advancing Saint-Gobain's unsolicited
tender offer. Your Board is in the process of reviewing Saint-Gobain's offer
with our financial and legal advisors and will provide you with our
recommendation regarding the offer and other possible alternatives prior to May
4, 2000.

     Specifically, Vetrotex is soliciting against proposal #2 on BTI's proxy.
This is a proposal to increase the number of shares available to all employees
under the 1997 Equity Incentive Plan (the "Plan"). Your Board of Directors
strongly believes this Plan is necessary in order to attract, retain, and
incentivize employees at all levels throughout the Company. This is especially
true when you consider that the unemployment rate in the Brunswick area is
approaching 2%. We urge you to vote FOR proposal #2 to allow your Company to
continue to motivate our dedicated and productive workforce.

                 VETROTEX'S SELF-SERVING, DISINGENUOUS ARGUMENT

     We believe that Vetrotex is being less than forthright in its annual
meeting campaign. Vetrotex attempts to cast the Plan in a negative light and
call into question certain features of the Plan. However, Vetrotex conveniently
fails to mention that VETROTEX VOTED TO APPROVE THE PLAN AS A SHAREHOLDER IN
1997 AND ONE OF ITS OWN EXECUTIVES, A DIRECTOR ON BRUNSWICK'S BOARD, ALSO
APPROVED THE VERY SAME PLAN.

     YOU SHOULD BE AWARE THAT DAVID SHARPE, A SENIOR EXECUTIVE OF VETROTEX, IS A
DIRECTOR OF BRUNSWICK. He notified Brunswick in March that he would not stand
for re-election at the annual meeting. He has recently advised Brunswick that he
desires to resign immediately upon Brunswick's meeting certain demands. MR.
SHARPE IS ALSO CHAIRMAN OF THE COMPENSATION COMMITTEE. As a member of the Board
of Directors of Brunswick, he was one of the people responsible for approving
the 1997 Equity Incentive Plan. Again in his role as Chairman of the
Compensation Committee he approved all options granted within the past two years
which have, at this point, depleted the Plan. The same principles that led to
the adoption of the Plan -- to attract, retain and incentivize employees and
directors of Brunswick -- apply as equally in 2000 as they did in 1997.

     We find it completely self-serving and disingenuous for Vetrotex to
challenge the amendment to the Plan when, in fact, its own employee, who has
been a Brunswick director since 1993 and is still Chairman of the Compensation
Committee, approved the Plan.

                         REJECT VETROTEX'S SOLICITATION
                        DO NOT SIGN ANY BLUE PROXY CARD

     We believe Vetrotex's campaign pertaining to the Annual Meeting is not
being waged for your benefit. We strongly urge shareholders to reject Vetrotex's
solicitation. Do not return any blue proxy card sent to you by Vetrotex. Do not
be misled by Vetrotex.

            SUPPORT YOUR COMPANY BY VOTING THE WHITE PROXY CARD NOW

     We appreciate your continued support.

                                Sincerely,

                                /s/ Martin S. Grimnes

                SIGN, DATE AND RETURN THE WHITE PROXY CARD TODAY

                          BRUNSWICK TECHNOLOGIES, INC.

               CORRECTION OF MINISTERIAL ERROR IN PROXY STATEMENT
               DATED APRIL 17, 2000 FOR MAY 16, 2000 ANNUAL MEETING
                                  OF STOCKHOLDERS

     Please be advised that due to a ministerial error, the Proxy Statement
dated April 17, 2000 relative to the annual meeting of stockholders incorrectly
stated that the amendment to the 1997 Equity Incentive Plan (Item 2 on the proxy
card) was a "routine" matter with respect to applicable broker rules, and that
the meeting agenda did not contain any "non-routine" matters with respect to
such rules. Item 2 is not a "routine" matter for purposes of applicable broker
rules. As stated in the Proxy Statement, brokers may not vote shares held in
"street name" on non-routine matters without specific instruction from the
beneficial owners.

     PLEASE NOTE THAT IF YOU HAVE ALREADY SUBMITTED A PROXY CARD, YOUR SHARES
WILL BE VOTED IN ACCORDANCE WITH THE RULES. IF YOU DID NOT VOTE "FOR" THE
AMENDMENT TO THE PLAN YOU MAY DO SO ON THE ENCLOSED PROXY CARD.
