                              10 THURBER BOULEVARD
                              SMITHFIELD, RI 02917
                             INFORMATION STATEMENT

    We are sending you this information statement to describe the proposed
merger between Bacou USA, Inc. and Daniel U. S. Sub, Inc., a wholly owned
subsidiary of Christian Dalloz S.A., a French company. The merger is part of a
global transaction which involves the combination of the businesses of Christian
Dalloz and the Bacou Group. The Bacou Group includes Bacou USA, Bacou S.A. (our
majority stockholder), and its parent company, Engineering Henri Bacou S.A. The
combination will occur by virtue of the merger and the acquisition by Christian
Dalloz of all of the shares of Bacou S.A. and Engineering Henri Bacou. If the
merger and the related acquisition transactions are completed, we will become a
subsidiary of Christian Dalloz, and your shares of Bacou USA common stock will
be converted into the right to receive cash. For each share of Bacou USA common
stock that you own, you will receive $28.50 in cash.

    An oversight committee of our board of directors, consisting of two board
members, Mr. Alfred J. Verrecchia and Mr. Karl F. Ericson, who are not officers
or employees of Bacou USA and who are independent of our majority stockholder,
represented the interests of our stockholders, other than Bacou S.A. and its
affiliates, in connection with the negotiations related to the merger agreement
and the merger. The oversight committee considered and evaluated the merger
agreement and the merger and unanimously recommended to the full board of
directors that the merger is fair to our stockholders other than Bacou S.A. and
its affiliates.

    In connection with its evaluation of the merger, the oversight committee
engaged UBS Warburg LLC to act as its financial advisor. On May 25, 2001 UBS
Warburg LLC rendered an oral opinion to the oversight committee, which was
subsequently confirmed in writing, to the effect that, as of such date and based
upon and subject to the matters set forth in such opinion, the consideration of
$28.50 per share in cash to be received by the stockholders of Bacou USA, other
than Bacou S.A., in the merger is fair from a financial point of view to such
stockholders. A copy of the written opinion of UBS Warburg LLC is attached as
Appendix B to the accompanying information statement, and you should read it
carefully.

    Our board of directors, after considering the unanimous recommendation of
the oversight committee, unanimously determined that the merger is fair to our
stockholders, other than Bacou S.A., and that the merger agreement and the
merger are advisable and in our best interests and the best interests of our
stockholders, other than Bacou S.A. Our board of directors unanimously approved
the merger agreement and the merger.

    Bacou S.A., representing more than 70% of the outstanding shares of Bacou
USA common stock, has already approved the merger by signing an irrevocable
written consent. No further vote of Bacou USA stockholders is necessary to
approve and adopt the merger agreement or the merger. WE ARE NOT ASKING YOU FOR
A PROXY AND YOU ARE REQUESTED NOT TO SEND US A PROXY. As we explain in this
information statement, however, completion of the merger is still subject to
satisfaction or waiver of a number of conditions, including various regulatory
approvals. We cannot predict with certainty when we will complete the merger,
but we hope to complete it no later than September 6, 2001.
<Page>
    If you object to the merger, you may elect to pursue your appraisal rights
to receive the statutorily determined "fair value" of your shares (which could
be more or less than the $28.50 per share merger consideration), but only if you
comply with the procedures under Delaware law. The applicable statutory
provisions relating to the procedures for asserting appraisal rights under
Delaware law are attached to the accompanying information statement as
Appendix C. Because we are not requesting your vote to approve the merger
agreement and the merger, it is important that you consider whether or not to
exercise appraisal rights.

    We urge you to read the accompanying information statement carefully as it
sets forth details of the proposed merger and other important information
related to the merger.

    NEITHER THE SECURITIES AND EXCHANGE COMMISSION NOR ANY STATE SECURITIES
COMMISSION HAS APPROVED OR DISAPPROVED THE MERGER, PASSED UPON THE MERITS OR
FAIRNESS OF THE MERGER OR DETERMINED IF THIS INFORMATION STATEMENT IS ACCURATE
OR ADEQUATE. ANY REPRESENTATION TO THE CONTRARY IS A CRIMINAL OFFENSE.

    THIS INFORMATION STATEMENT IS DATED AUGUST   -  , 2001, AND WAS FIRST MAILED
TO STOCKHOLDERS OF BACOU USA ON OR ABOUT AUGUST   -  , 2001.

                                          Sincerely,

                                          /s/ PHILIP B. BARR

                     QUESTIONS AND ANSWERS ABOUT THE MERGER

Q: WHAT IS THE PROPOSED TRANSACTION?

A. Daniel U. S. Sub, Inc., a wholly owned subsidiary of Christian Dalloz S.A.,
    will merge with and into Bacou USA, Inc., with Bacou USA being the surviving
    corporation in the merger. This merger is part of a global transaction
    pursuant to which the business of Christian Dalloz will be combined with the
    business of the Bacou Group. For a more detailed discussion of these
    transactions, see "SPECIAL FACTORS--The Global Transaction."

Q: WHAT WILL I BE ENTITLED TO RECEIVE IN THE MERGER?

A: If the merger is completed, each of your shares of common stock will be
    converted into the right to receive $28.50 in cash, without interest.

Q: WHY IS THERE NO STOCKHOLDER VOTE?

A: Bacou S.A., as our majority stockholder, has given its irrevocable written
    consent to the merger. Bacou S.A. holds voting power over more than 70% of
    our common stock. Its written consent to the merger satisfied the
    stockholder approval requirements for the merger under Delaware law and
    under our Certificate of Incorporation and Bylaws. Therefore, no additional
    stockholder vote is necessary.

Q: WHY DID I RECEIVE THIS INFORMATION STATEMENT?

A: Applicable laws require us to provide you information regarding the merger,
    even though your vote is neither required nor requested to complete the
    merger. You should use this information to determine whether or not you wish
    to exercise appraisal rights.

Q: WHEN DO YOU EXPECT THE MERGER TO BE COMPLETED?

A: We are working towards completing the merger as soon as possible. For the
    merger to occur, we must obtain certain governmental and other third party
    approvals and satisfy certain other conditions. The merger is also
    conditioned on the satisfaction of all the conditions precedent to the
    related acquisitions of Bacou S.A. and Engineering Henri Bacou (other than
    completion of the merger) described in detail under "SPECIAL FACTORS--The
    Global Transaction." Nevertheless, we hope to complete the merger by
    September 6, 2001. However, delays in obtaining regulatory approvals could
    delay the merger. See "THE MERGER--Regulatory Approvals and Other Consents."

Q: WHAT DO I NEED TO DO NOW?

A: You do not need to do anything now. This information statement is for your
    information only and it does not require or request you to take any action.
    You will need to take certain actions within a specified period of time
    should you elect to exercise your appraisal rights.

Q: WHAT SHOULD I DO WITH MY SHARES?

A: Shortly after the merger is completed, you will receive a letter of
    transmittal with instructions informing you how to send in your stock
    certificates to Christian Dalloz' paying agent. You should use the letter of
    transmittal to exchange stock certificates for the merger consideration to
    which you are entitled as a result of the merger. Please do not send your
    share certificates until you receive the instructions and the letter of
    transmittal. You should follow the procedures described in "THE
    MERGER--Payment of Merger Consideration and Surrender of Stock
    Certificates."

Q: WHO CAN HELP ANSWER MY OTHER QUESTIONS?

A: If you have more questions about the merger, you should contact:

COMBINATION OF THE BACOU GROUP AND CHRISTIAN DALLOZ

    Daniel U. S. Sub Inc., a wholly owned subsidiary of Christian Dalloz S.A.,
will merge with and into Bacou USA, Inc. with Bacou USA being the surviving
corporation in the merger. This merger is part of a global transaction pursuant
to which the business of Christian Dalloz will be combined with the business of
the Bacou Group. The Bacou Group includes Bacou USA, Bacou S.A. (our majority
stockholder), and its parent company, Engineering Henri Bacou S.A. Bacou S.A.
and Engineering Henri Bacou are privately held companies, which, in addition to
their direct and indirect equity ownership of Bacou USA, manufacture and
distribute personal protection equipment and other products principally in
Western Europe. The combination will occur by virtue of this merger and the
acquisition by Christian Dalloz of all of the shares of Bacou S.A. and
Engineering Henri Bacou. The results of the merger and these related
transactions are: (1) Christian Dalloz will acquire 100% ownership of the Bacou
Group, (2) Christian Dalloz will change its name to Bacou-Dalloz, (3) the
shareholders of Bacou S.A. and Engineering Henri Bacou, including the Bacou
family and Sauvegarde LLC (an entity owned by certain members of our senior
management), will receive in exchange for their shares of Bacou S.A. and
Engineering Henri Bacou cash in the aggregate amount of approximately 1.7
billion French francs ($221,481,057) and 2,906,392 shares of Christian Dalloz
representing approximately 40% of the shares of Bacou-Dalloz following the
combination, (4) Bacou USA will become a wholly owned subsidiary of Christian
Dalloz and (5) Bacou USA's minority stockholders will have the right to receive
$28.50 per share in cash. Completion of the related transactions is subject to
many conditions, including a financing condition, which, if not satisfied, will
result in the termination of the related transaction. If the related
transactions are terminated, this merger will also be terminated. For a more
detailed discussion of these transactions, see "SPECIAL FACTORS--The Global
Transaction."

    The following charts set forth the structure of the Bacou Group and
Christian Dalloz group prior to and following the merger and the related
acquisition transactions:

                                     [LOGO]

    The aggregate equity value of the Bacou Group (including Bacou USA) as
negotiated by the Bacou family and Christian Dalloz, is $596,900,000 (assuming
exchange rates of 7.3 French francs/$1.00 and 1.113 Euro/$1.00, which exchange
rates were agreed upon by the parties in connection with the valuation of the
transaction, and assuming that the Christian Dalloz shares are valued at 77
Euro). There are 5,069,065 Bacou USA shares outstanding that are held by
stockholders other than Bacou S.A. At a price of $28.50 per share these
stockholders will be entitled to receive an aggregate of $144,468,352.50 of
merger consideration. Accordingly, the aggregate equity value of the Bacou Group
(including the shares of Bacou USA owned by Bacou S.A. with an aggregate value
of $359,459,100 based on the $28.50 merger consideration) allocable to the
stockholders of Bacou S.A. and Engineering Henri Bacou is $452,432,000. This
information has been provided for convenience only. Bacou USA believes that
Bacou S.A. and Bacou USA are not directly comparable entities.

THE MERGER

    The merger agreement provides for the merger of Daniel U. S. Sub, a wholly
owned subsidiary of Christian Dalloz, with and into Bacou USA, with Bacou USA
continuing as the surviving corporation. The merger is part of a global
transaction which involves the combination of the businesses of Christian Dalloz
and the Bacou Group. If the merger and the related acquisition transactions are
completed, Bacou USA will become a subsidiary of Christian Dalloz. See "SPECIAL
FACTORS--The Global Transaction" for more information about the related
transactions and "THE MERGER" for more information regarding the merger.

PURPOSE OF THE MERGER

    The principal purposes of the merger are to enable Christian Dalloz to
acquire all of our shares, other than shares held by Bacou S.A., and to provide
you the opportunity to receive a cash price for your shares at a premium over
the market price at which the common stock traded before the announcement on
May 30, 2001 of the merger and the related acquisition transactions. Our board
of directors believes that the merger is fair to and in the best interests of
our stockholders, other than

                                       4
<Page>
Bacou S.A. See "SPECIAL FACTORS--Reasons for the Approvals by the Oversight
Committee and our Board of Directors" and "SPECIAL FACTORS--Purpose and
Structure of the Merger."

OUR MAJORITY STOCKHOLDER; NO FURTHER STOCKHOLDER APPROVAL REQUIRED

    Bacou S.A., as our majority stockholder, signed and delivered to Christian
Dalloz a written consent and irrevocable proxy pursuant to which Bacou S.A.
approved and adopted the merger agreement and the merger. See "THE MERGER--The
Stockholder Agreement." At the time of delivery of the written consent, Bacou
S.A. held approximately 71.4% of our shares eligible to vote on the merger. Its
consent was sufficient for stockholder approval and adoption of the merger
agreement and the merger under Delaware law, our Certificate of Incorporation
and Bylaws. Therefore, we are not asking you to vote on the merger. See "SPECIAL
FACTORS--The Majority Stockholder; No Further Stockholder Approval Required" for
more information regarding the consent of our majority stockholder.

EFFECTS OF THE MERGER

    As a result of the merger and the related acquisitions, Engineering Henri
Bacou, Bacou S.A. and Bacou USA will be wholly owned subsidiaries of Christian
Dalloz. The shares of Bacou USA will no longer be traded on the NYSE. In
addition, the registration of our shares under the Securities and Exchange Act
of 1934 will be terminated. Accordingly, following the merger, there will be no
publicly traded Bacou USA common stock outstanding. See "SPECIAL
FACTORS--Certain Effects of the Merger" for more information regarding the
effects of the merger.

APPROVAL OF THE OVERSIGHT COMMITTEE AND OUR BOARD OF DIRECTORS

    The independent oversight committee of our board of directors, consisting of
two board members, Mr. Alfred J. Verrecchia and Mr. Karl F. Ericson, who are not
officers or employees of Bacou USA and who are independent of our majority
stockholder, represented the interests of our stockholders, other than Bacou
S.A. and its affiliates, in connection with the negotiations regarding the
merger agreement and the merger. The oversight committee considered and
evaluated the merger agreement and the merger and unanimously recommended to the
full board of directors that the merger is fair to our stockholders, other than
Bacou S.A and its affiliates. In considering the approval of the oversight
committee with respect to the merger agreement and the merger, you should be
aware that the members of the oversight committee have options to purchase our
common stock. These options will become fully vested at the time of the merger
and the members of the oversight committee will be entitled to receive, for each
share covered by their options, an amount in cash equal to the difference
between the $28.50 per share merger consideration and the per share exercise
price of each option. The members of the oversight committee in the aggregate
hold options to purchase 40,400 shares and the aggregate cash payment they will
receive for such options is $452,058. See "SPECIAL FACTORS--Interests of Certain
Parties in the Merger and Related Acquisition Transactions; Potential Conflicts
of Interest."

    Our board of directors, after considering the unanimous recommendation of
the oversight committee, unanimously determined that the merger is fair to our
stockholders, other than Bacou S.A., and that the merger agreement and the
merger are advisable and in our best interests and the best interests of our
stockholders, other than Bacou S.A. Accordingly, our board of directors
unanimously approved the merger agreement and the merger. For a discussion of
the material factors considered by the oversight committee and our board of
directors in reaching their conclusions, see "SPECIAL FACTORS--Reasons for the
Approval by the Oversight Committee and our Board of Directors."

OPINION OF UBS WARBURG LLC

    In connection with the merger, the oversight committee and our board of
directors considered the opinion of the oversight committee's financial advisor,
UBS Warburg LLC, as to the fairness from a financial point of view of the
consideration to be received in the merger by our stockholders, other than Bacou
S.A. UBS Warburg LLC rendered its oral opinion to the oversight committee on
May 25,

                                       5
<Page>
2001, which was subsequently confirmed in writing that, as of the date of the
opinion and based on and subject to the matters set forth in the opinion, the
consideration of $28.50 per share in cash to be received by our stockholders,
other than Bacou S.A., in the merger is fair from a financial point of view to
such stockholders. See "SPECIAL FACTORS--Opinion of UBS Warburg LLC."

    The full text of UBS Warburg LLC's written opinion is attached as
Appendix B to this information statement. We encourage you to read UBS Warburg
LLC's opinion in its entirety for a description of the assumptions made, matters
considered and limitations on the review undertaken.

BACOU USA'S POSITION AS TO THE FAIRNESS OF THE MERGER

    We believe that the merger is fair to our stockholders who are unaffiliated
with Bacou S.A. In reaching this determination we have relied on numerous
factors, including:

    - the fact that the merger consideration (1) represents a 46.2% premium over
      the closing price of our common stock on the last full trading day prior
      to our announcement on July 10, 2000, that we and Bacou S.A. would explore
      strategic alternatives to enhance stockholder value, and a 20% premium
      over the closing price of our common stock on the last full trading day
      prior to Christian Dalloz' May 30, 2001 announcement of the merger
      agreement, and (2) was higher than our 52-week and all-time high closing
      price of $28.38 set on January 22, 2001;

    - the fact that the merger was unanimously approved and recommended by the
      oversight committee consisting of two directors, Mr. Alfred J. Verrecchia
      and Mr. Karl F. Ericson, who are not employees or officers of Bacou USA
      and who are independent of Bacou S.A., our majority stockholder; and

    - the fact that UBS Warburg LLC delivered an opinion to the oversight
      committee to the effect that, as of the date of the opinion and subject to
      the matters set forth in the opinion, the consideration of $28.50 per
      share in cash to be received by our stockholders, other than Bacou S.A.
      and its affiliates, in the merger is fair from a financial point of view
      to such stockholders.

    For a more detailed discussion of the material factors upon which these
beliefs are based, see "SPECIAL FACTORS--Bacou USA's Position as to the Fairness
of the Merger."

BACOU S.A.'S, ENGINEERING HENRI BACOU'S AND THE BACOU FAMILY'S POSITIONS AS TO
THE FAIRNESS OF THE MERGER

    Each of Bacou S.A., Engineering Henri Bacou and each of Jacqueline Maggi
Bacou, Philippe Bacou, Christophe Bacou and Veronique Mirabel (we refer to these
individuals as the "Bacou family") believes that the consideration to be
received in the merger by our stockholders who are unaffiliated with Bacou S.A.,
is fair to such stockholders and that the merger is procedurally fair to our
stockholders who are unaffiliated with Bacou S.A. For a more detailed discussion
of the material factors upon which these beliefs are based, see "SPECIAL
FACTORS--Bacou S.A.'s, Engineering Henri Bacou's and the Bacou Family's
Positions as to the Fairness of the Merger."

MESSRS. STEPAN'S, BARR'S, BENNETT'S AND HEBERT'S POSITION AS TO FAIRNESS OF THE
  MERGER

    Each of Messrs. Stepan, Barr, Bennett and Hebert believes that the
consideration to be received in the merger by our stockholders who are
unaffiliated with Bacou S.A. is fair to such stockholders and that the merger is
procedurally fair to our stockholders who are unaffiliated with Bacou S.A. For a
more detailed discussion of the material factors upon which these beliefs are
based, see "SPECIAL FACTORS--Messrs. Stepan's, Barr's, Bennett's and Hebert's
Position as to the Fairness of the Merger."

CHRISTIAN DALLOZ' AND DANIEL U. S. SUB'S POSITION AS TO THE FAIRNESS OF THE
  MERGER

    Each of Christian Dalloz and Daniel U. S. Sub believes that the
consideration to be received in the merger by our stockholders unaffiliated with
Bacou S.A. is fair to such holders and that the merger is procedurally fair to
Bacou USA stockholders unaffiliated with Bacou S.A. For a detailed discussion

                                       6

FACTORS--Christian Dalloz' and Daniel U. S. Sub's Position as to the Fairness of
the Merger."

INTERESTS OF CERTAIN PARTIES IN THE MERGER AND RELATED ACQUISITION TRANSACTIONS;
  POTENTIAL CONFLICTS OF INTEREST

    In considering the approval of our board of directors with respect to the
merger agreement and the merger, you should be aware that, in addition to the
matters discussed above, certain of our executive officers and members of our
board of directors have interests in the merger and the related acquisitions of
Bacou S.A. and Engineering Henri Bacou that may be different from or in addition
to the interests of our other stockholders in the merger and that may constitute
conflicts of interest. See "SPECIAL FACTORS--Interests of Certain Parties in the
Merger and Related Acquisition Transactions; Potential Conflicts of Interest."

    - Our directors (including the members of the oversight committee) and
      executive officers have options to purchase our common stock. These
      options will become fully vested at the time of the merger. Our executive
      officers and directors will be entitled to receive, for each share covered
      by their options, an amount in cash equal to the difference between the
      $28.50 per share merger consideration and the per share exercise price of
      each option as follows:

    - Sauvegarde LLC, an entity owned by Mr. Barr, Mr. Stepan, Mr. Hebert and
      Mr. Bennett, owns 188,381 shares of Bacou S.A. which Sauvegarde has agreed
      to sell to Christian Dalloz for aggregate cash consideration of
      525,055,523 French francs ($68,405,795). Sauvegarde purchased these shares
      pursuant to a Share Option Purchase Agreement, dated as of July 8, 2000
      (as amended), with Mevra Beheer BV, pursuant to which Mevra Beheer granted
      to Sauvegarde an option to purchase such shares. Sauvegarde made an
      initial deposit of 14,000,000 French francs ($1,823,962) to purchase these
      shares from Mevra Beheer and if the sale of these shares is completed,
      Sauvegarde will be obligated to pay an additional 326,000,000 French
      francs ($42,472,250) plus interest, to satisfy its remaining obligations
      to Mevra Beheer. If the sale is not completed, Sauvegarde will have to
      return the shares to Mevra Beheer and will forfeit the deposit. The price
      per share payable by Sauvegarde for these Bacou S.A. shares is 1,804.84
      French francs ($235) excluding any accrued interest on the balance of the
      purchase price, and the price per share to be received by Sauvegarde upon
      the sale of such shares is 2,787 French francs ($363). Additionally,
      Sauvegarde will use 71,520,304 French francs ($9,317,878) to purchase
      141,600 Christian Dalloz shares from Jacqueline Maggi Bacou. As a result
      of these

    - Messrs. Philippe Bacou and Christophe Bacou, who are brothers and are
      members of our board of directors, own shares of common stock of Bacou
      S.A. and of Engineering Henri Bacou. Upon completion of the acquisitions
      of Bacou S.A. and Engineering Henri Bacou and related transactions,
      Messrs. Philippe Bacou and Christophe Bacou will directly receive an
      aggregate of 186,244,054 French francs ($24,264,429) in cash. The per
      share purchase price to be received for the sale of these Bacou S.A.
      shares is 2,787 French francs ($363). The per share price to be received
      for the sale of these Engineering Henri Bacou shares is 90,839.8 French
      francs ($11,835). The aggregate amounts do not include proceeds
      attributable to the sale of Bacou S.A. and Engineering Henri Bacou shares
      owned by Indivision Bacou, which is an entity jointly owned by several
      members of the Bacou family. See "SPECIAL FACTORS--Interests of Certain
      Parties in the Merger and Related Acquisition Transactions; Potential
      Conflicts of Interest--Ownership of Common Stock of Bacou S.A. and
      Engineering Henri Bacou."

    - At the outset of the initial auction process, Mr. Philippe Bacou expressed
      to Messrs. Stepan and Hebert, the Bacou family's willingness to pay an
      aggregate of $15,000,000 to Messrs. Stepan, Barr, Hebert and Bennett in
      recognition of the important role that they would be expected to play in
      structuring and negotiating the sale of the Bacou Group. The oversight
      committee ultimately objected to this arrangement and Messrs. Barr,
      Hebert, Bennett and Stepan have forfeited their right to any such payment.

    - Indemnification arrangements and directors' and officers' liability
      insurance for our present and former directors and officers will be
      continued by the surviving corporation after the merger for acts or
      omissions occurring prior to the effective time of the merger. See
      "SPECIAL FACTORS--Interests of Certain Parties in the Merger and Related
      Acquisition Transactions--Indemnification and Insurance."

    - Messrs. Philippe Bacou, Christophe Bacou, Howard Leight and Walter Stepan,
      who are directors of Bacou USA, are also directors and/or officers of
      Bacou S.A. See "SPECIAL FACTORS--Interests of Certain Parties in the
      Merger and Related Acquisition Transactions; Potential Conflicts of
      Interest--Affiliations of Certain Executive Officers and Directors with
      Bacou S.A."

ACCOUNTING TREATMENT

    After completion of the merger and the related acquisitions of Bacou S.A.
and Engineering Henri Bacou, Bacou USA will be a wholly owned subsidiary of a
French company. We will not be required to comply with U.S. generally accepted
accounting principles (GAAP) and will be part of a consolidated group under
French GAAP.

MATERIAL U.S. FEDERAL INCOME TAX CONSEQUENCES

    The receipt of $28.50 in cash for each share of common stock pursuant to the
merger will be a taxable transaction for U.S. federal income tax purposes and
under most state, local, foreign and other tax laws. For U.S. federal income tax
purposes, each of our stockholders generally will realize taxable gain or loss
as a result of the merger measured by the difference, if any, between the tax
basis of each share of our common stock owned by such stockholder and $28.50.
Each holder of a compensatory option to acquire our common stock who receives a
cash payment equal to the difference between $28.50 and the exercise price per
share of such option generally will have ordinary income to the extent

                                       9

of the cash received. For additional information regarding material U.S. federal
income tax consequences of the merger to our stockholders, see "SPECIAL
FACTORS--Material U.S. Federal Income Tax Consequences of the Merger to our
Stockholders."

THE MERGER AGREEMENT

    - EFFECTIVE TIME OF MERGER

     The merger will become effective upon the filing of a duly executed
     certificate of merger with the Secretary of State of the State of Delaware
     or at such later time as otherwise agreed by Christian Dalloz and Bacou USA
     and as specified in the certificate of merger. The filing will occur after
     (1) all conditions to the merger contained in the merger agreement have
     been satisfied or waived and (2) all conditions to the consummation of the

     obligation to effect the merger see "THE MERGER--The Merger
     Agreement--Conditions to the Merger" and "SPECIAL FACTORS--The Global
     Transaction."

    - NO SOLICITATION OF OTHER OFFERS

     The merger agreement provides that neither we nor any of our
     representatives will take any action:

       - directly or indirectly, to solicit, initiate or encourage, take any
         action to facilitate any inquiry, or enter into any agreement regarding
         the making of any proposal with respect to certain acquisition
         proposals by third parties;

       - to withdraw or modify in a manner adverse to Christian Dalloz or Daniel
         U. S. Sub the approval or recommendation by the board of directors or
         any committee of the board of directors of the merger agreement or the
         merger;

       - to approve or propose to approve any letter of intent or agreement
         relating to any company takeover proposal; or

       - to participate, directly or indirectly, in any discussions or
         negotiations with, or furnish any information to, any person relating
         to any such acquisition proposal.

     The merger agreement provides, however, that if prior to receipt of our
     stockholder approval, which has been obtained pursuant to the written
     consent of Bacou S.A. (our majority stockholder) executed on August 3,
     2001, our board of directors receives a superior proposal for the purchase
     of our common stock or assets and as a result of the superior proposal the
     oversight committee determines in good faith, after receiving advice from
     its outside legal counsel, that failure to take such action would
     constitute a breach of the board of directors' fiduciary duties to our
     stockholders under applicable law, then the oversight committee (and the
     board of directors acting on the recommendation of the oversight committee)
     may withdraw or modify its approval or recommendation of the merger
     agreement and the merger and disclose such withdrawal or modification to
     our stockholders.

     If we receive an acquisition proposal or inquiry for over 15% of our equity
     securities from a third party or any proposal or inquiry regarding a
     merger, we will keep Christian Dalloz fully informed of the status of any
     such proposal or inquiry.

     For additional information regarding the agreement not to solicit other
     offers, see "THE MERGER--The Merger Agreement--No Solicitation of Other
     Offers."

    - TERMINATION OF MERGER AGREEMENT

     The merger agreement may be terminated at any time prior to closing,
     whether before or after receipt of Bacou USA stockholder approval:

       - by mutual written consent of Christian Dalloz, Daniel U. S. Sub and us;

       - by either us or Christian Dalloz if the merger is not completed on or
         prior to December 31, 2001, and the terminating party is not in breach
         of the merger agreement;

       - by either us or Christian Dalloz if a governmental entity issues a
         final, non-appealable ruling permanently restraining or prohibiting the
         merger;

       - by either us or Christian Dalloz if, upon a vote at a duly held meeting
         to obtain our stockholder approval, such approval is not obtained;

                                       11
<Page>
       - by either us or Christian Dalloz if the agreements forming or governing
         the related acquisitions of Bacou S.A. and Engineering Henri Bacou are
         terminated in accordance with their terms; or

       - by Christian Dalloz, if we materially breach any covenant,
         representation or warranty in the merger agreement, but only if the
         breach results in (1) a failure of a representation or warranty given
         by us or (2) our failure to perform an obligation, and such breach
         cannot be or has not been cured within 30 days after we have been given
         written notice of such breach.

     There is no provision in the merger agreement requiring a payment of a
     termination fee by any party. For additional information regarding the
     ability of the parties to terminate the merger agreement see "THE
     MERGER--The Merger Agreement--Termination of the Merger Agreement."

    - AMENDMENTS TO THE MERGER AGREEMENT

     The merger agreement may be amended only in writing by each of the parties
     to the merger agreement. After our stockholders have approved the merger
     agreement, no amendment to the merger agreement may be made which by law
     requires further approval of our stockholders without obtaining such
     further approval. For additional information regarding the ability of the
     parties to amend the merger agreement, see "THE MERGER--The Merger
     Agreement--Amendment to the Merger Agreement."

    - REGULATORY APPROVALS

     Christian Dalloz is required to make filings with or obtain approvals from
     certain United States and foreign antitrust regulatory authorities in
     connection with the merger, including a filing under the Hart-Scott-Rodino
     Antitrust Improvements Act of 1976 and a filing under the merger
     regulations of the Republic of Ireland. An application and notice was filed
     with the Federal Trade Commission and the Department of Justice on June 8 ,
     2001, and the applicable waiting period under the Hart-Scott-Rodino Act
     terminated on July 9, 2001. For additional information regarding regulatory
     approvals see "THE MERGER--Regulatory Approvals and Other Consents."

    - FINANCING OF THE MERGER; FEES AND EXPENSES OF THE MERGER

     Christian Dalloz plans to fund the merger and the related acquisitions of
     Bacou S.A. and Engineering Henri Bacou and to pay related fees and
     expenses, directly or indirectly, through a combination of cash on hand,
     and proceeds from debt provided by BNP Paribas and J.P. Morgan plc.
     Although the merger agreement does not contain an explicit financing
     condition, the related acquisitions of Bacou S.A. and Engineering Henri
     Bacou are conditioned on obtaining financing substantially in accordance
     with the commitment letter and term sheets received from BNP Paribas and
     J.P. Morgan. Because completion of the merger is conditioned on completion
     of these related acquisitions, the merger is in effect subject to a
     financing condition. The commitment letter and term sheets, received by
     Christian Dalloz on May 29, 2001, indicate the commitment of BNP Paribas
     and J.P. Morgan, as joint arrangers, to arrange for senior secured credit
     facilities, totaling 2.7 billion French francs ($351,764,032) and
     $291 million, for the purpose of effecting the merger and the related
     acquisitions of Bacou S.A. and Engineering Henri Bacou. Of this amount,
     627.8 million French francs ($81,791,652) constitutes a five year
     multi-currency revolving group facility and the balance is divided into
     three term loans, each with a five year maturity. The final maturity date
     for each of the facilities is June 30, 2006.

     The principal stockholders of Bacou S.A. and Engineering Henri Bacou will
     pay any expenses incurred in connection with the merger and the related
     acquisitions of Bacou S.A. and

                                       12
<Page>
     Engineering Henri Bacou which exceed $21.3 million in the aggregate and
     fall into one of the following categories:

       - legal, accounting and other professional fees, excluding post-closing
         legal fees and professional fees relating to minority shareholder
         litigation;

       - investment banking fees and expenses;

       - costs and expenses of the oversight committee, to be paid by Bacou USA
         in accordance with the U.S. merger agreement; and

       - bonuses or "change of control" payments to officers and employees of
         the Bacou Group triggered by the change of control of the Bacou Group.

     For additional information regarding financing of the related acquisition
     transactions and the merger, see "THE MERGER--Financing of the Merger; Fees
     and Expenses of the Merger."

SHARE OPTION PURCHASE AGREEMENT

    Sauvegarde LLC, an entity owned by Mr. Barr, Mr. Stepan, Mr. Hebert and
Mr. Bennett, Protection Participation, an entity managed by Mr. Philippe Bacou,
and Hobar Corporation BV, an entity unaffiliated with Bacou USA, Bacou S.A., the
Bacou family, Sauvegarde and Protection Participation, entered into a Share
Option Purchase Agreement on July 8, 2000 with Mevra Beheer BV, an entity
controlled by Vandeputte International NV. Pursuant to the Share Option Purchase
Agreement, Mevra Beheer BV granted to Sauvegarde, Protection Participation and
Hobar Corporation an irrevocable option to purchase an aggregate of 470,953
shares of Bacou S.A. owned by Mevra Beheer BV. On September 1, 2000 Sauvegarde,
Protection Participation and Hobar Corporation exercised their option for an
aggregate non-refundable initial deposit of 35,000,000 French francs
($4,559,904) and those three entities purchased the Bacou S.A. shares subject to
the option. On May 29, 2001 an additional installment of purchase price
totalling 55,000,000 French francs ($7,165,563) for the option shares was paid
by Protection Participation and Hobar Corporation, thereby completing payment
for an aggregate of 34,249 option shares. Sauvegarde did not participate in such
payment. The Share Option Purchase Agreement provides that if Bacou S.A. is
sold, then Sauvegarde, Protection Participation and Hobar Corporation will pay
the aggregate balance of the purchase price of 753,185,214 French francs
($98,127,210) plus interest at the time of sale. The Share Option Purchase
Agreement further provides that if a sale of Bacou S.A. is not consummated by
December 31, 2001, 436,704 option shares must be returned to Mevra Beheer and
the deposit already made with respect to such shares will be forfeited.

APPRAISAL RIGHTS

    Stockholders who object to the merger may elect to pursue their appraisal
rights to receive the statutorily determined "fair value" of their shares (which
may be more or less than the $28.50 per share merger consideration), but only if
they comply with the procedures under Delaware law. Because you are not being
asked to vote to approve the merger agreement and the merger, it is important
that you consider whether or not to exercise appraisal rights. For more
information regarding these procedures, see "THE MERGER--Appraisal Rights."

EXCHANGE RATE

    The amounts provided in this information statement are stated in the
currencies in which payments of such amounts will be made. For convenience, U.S.
dollar equivalent amounts are listed in parenthesis for all amounts listed in
French francs. The U.S. dollar equivalent amounts were calculated using the
closing mid-range exchange rate of French francs to U.S. dollars published in
The Wall Street Journal on July 16, 2001 (FF7.6756=$1.00). The exchange rate
used for the purpose of calculating the U.S. dollar equivalents of amounts in
French francs in this information statement may differ from the exchange rate
which will be used at the consummation of the merger and the related acquisition
transactions to determine the dollar equivalents of amounts in French francs.

                                  INTRODUCTION

    We are furnishing this information statement to you in connection with the
proposed merger between Bacou USA and Daniel U. S. Sub in which Bacou USA will
be the surviving corporation. Daniel U. S. Sub is a Delaware corporation and
wholly owned subsidiary of Christian Dalloz, which was formed for the purpose of
effecting the merger. The merger is part of a global transaction pursuant to
which the business of Christian Dalloz will be combined with the business of the
Bacou Group. The Bacou Group includes Bacou USA, Bacou S.A. (our majority
stockholder), and its parent company, Engineering Henri Bacou. Bacou S.A. and
Engineering Henri Bacou are privately held companies, which, in addition to
their direct and indirect equity ownership of Bacou USA, manufacture and
distribute personal protection equipment and other products principally in
Western Europe. The combination will occur by virtue of this merger and the
acquisition by Christian Dalloz of all of the shares of Bacou S.A. and
Engineering Henri Bacou. The results of the merger and these related
transactions are: (1) Christian Dalloz will acquire 100% ownership of the Bacou
Group, (2) Christian Dalloz will change its name to Bacou-Dalloz, (3) the
shareholders of Bacou S.A. and Engineering Henri Bacou, including the Bacou
family and Sauvegarde LLC (an entity owned by certain members of our senior
management), will receive in exchange for their shares of Bacou S.A. and
Engineering Henri Bacou S.A. cash in the aggregate amount of approximately
1.7 billion French francs ($221,481,057) and 2,906,392 million shares of
Christian Dalloz representing approximately 40% of the shares of Bacou-Dalloz
following the combination, (4) Bacou USA will become a wholly owned subsidiary
of Christian Dalloz and (5) Bacou USA's minority stockholders will have the
right to receive $28.50 per share in cash. Completion of the related
transactions is subject to many conditions, including a financing condition,
which, if not satisfied, will result in the termination of the related
transactions. If the related acquisition transactions are terminated, this
merger will also be terminated. This merger will be carried out as provided in
the Agreement and Plan of Merger, dated as of May 29, 2001, among Christian
Dalloz, Daniel U. S. Sub and Bacou USA. A copy of the merger agreement is
attached as Appendix A to this information statement. This information statement
has been sent to you because on August 3, 2001, the date on which the majority
stockholder executed a written consent adopting the merger agreement and
approving the merger, you were a holder of Bacou USA common stock, par value
$.001 per share.

    In the merger, each share of our common stock owned by our stockholders,
other than Bacou S.A., will be converted into the right to receive $28.50 in
cash (as described below under "THE MERGER--The Merger Agreement--Consideration
to be Received by the Stockholders").

    The following charts set forth the structure of the Bacou Group and
Christian Dalloz group prior to and following the merger and the related
acquisition transactions:

                                     [LOGO]

    The aggregate equity value of the Bacou Group (including Bacou USA) as
negotiated by the Bacou family and Christian Dalloz, is $596,900,000 million
(assuming exchange rates of 7.3 French francs/$1.00 and 1.113 Euro/$1.00, which
exchange rates were agreed upon by the parties in connection with the valuation
of the transaction, and assuming that the Christian Dalloz shares are valued at
77 Euro). There are 5,069,065 Bacou USA shares outstanding that are held by
stockholders other than Bacou S.A. At a price of $28.50 per share these
stockholders will be entitled to receive an aggregate of $144,468,352.50 of
merger consideration. Accordingly, the aggregate equity value of the Bacou Group
(including the shares of Bacou USA owned by Bacou S.A. with an aggregate value
of $359,459,100 based on the $28.50 merger consideration) allocable to the
stockholders of Bacou S.A. and Engineering Henri Bacou is $452,432,000. This
information has been provided for convenience only. Bacou USA believes that
Bacou S.A. and Bacou USA are not directly comparable entities.

    This information statement is to inform you of the merger. Your vote is not
required for the merger because our majority stockholder, Bacou S.A., executed
and delivered to Christian Dalloz an irrevocable written consent approving and
adopting the merger agreement and the merger. At the time Bacou S.A. signed the
written consent, it was the record owner of 12,612,600 shares of our common
stock. Each of these shares is entitled to one vote and, in the aggregate, these
shares represented approximately 71.4% of our shares eligible to vote on the
merger. This means that Bacou S.A. represented the requisite majority of the
votes entitled to be cast at a meeting of our stockholders to consider the
merger agreement and the merger. As a result, no meeting or further approval or
consent of our stockholders is necessary to effect the merger. The merger will
become effective no earlier than 20 business days after this information
statement is mailed to our stockholders, and only after satisfaction or waiver
of the conditions to the merger contained in the merger agreement.

    We are mailing this information statement to stockholders on or about
August   , 2001.

    and Handling Fees and Costs." This pronouncement was effective for the
    Company beginning on October 1, 2000, and required that amounts billed to
    customers for shipping and handling should be classified as sales. Prior to
    the effective date, reimbursements received from customers for shipping and
    handling costs had been classified as a reduction of the related expense. As
    required by this pronouncement, Bacou USA has reclassified reimbursements
    for all prior periods presented to sales.

RECENT DEVELOPMENTS

    On May 30, 2001, four putative class action complaints were filed in the
Delaware Court of Chancery on behalf of our public stockholders against us, our
directors and Bacou S.A. One of the complaints also includes Christian Dalloz as
a defendant. Each of the complaints alleges, among other things, that the
defendants breached their fiduciary duties in setting an unreasonably low price
to be paid to our public stockholders in the merger. The complaints seek a
preliminary and permanent injunction enjoining the proposed transaction,
rescission in the event that the transaction is completed, damages and
attorneys' fees. Bacou USA and Christian Dalloz believe that these claims are
without merit and intend to defend them vigorously.

                                SPECIAL FACTORS

BACKGROUND OF THE MERGER AND THE RELATED ACQUISITION TRANSACTIONS

    DETERMINATION OF BACOU FAMILY TO PURSUE A SALE OF THE BACOU GROUP

    The industry in which Bacou S.A. and Bacou USA operates is undergoing
consolidation. This trend may reflect the relatively low levels of organic
growth experienced by U.S. personal protective equipment manufacturers in recent
years. In part, to address this trend, the Bacou Group, including Bacou USA, had
a long-term strategic plan of pursuing growth through acquisition. Management of
Bacou S.A. and Bacou USA believed that such growth was necessary for the Bacou
Group to compete successfully with ever larger competitors and to capitalize on
potential economies of scale. This strategy required the Bacou Group to raise
significant additional debt or equity capital from sources other than cash flow
from operations. The private ownership structure of Bacou S.A. and the limited
liquidity of Bacou USA's equity, imposed significant constraints on the ability
of the Bacou Group, and Bacou USA, to raise the capital necessary to pursue
successfully its long term growth strategy. For example, in 1998 Bacou USA had
attempted to complete a secondary offering of its common stock. The indicative
pricing of that offering, however, was unsatisfactory and the offering was
abandoned before it was completed. Prior to Bacou USA's announcement that it
would explore strategic alternatives, the historic prices at which Bacou USA's
shares of common stock were trading represented multiples of Bacou USA's
earnings that were lower than the trading multiples of many companies that might
otherwise have been acquisition candidates for Bacou USA. Therefore, raising
equity capital at such multiples would have been unacceptably expensive for the
purpose of pursuing possible acquisitions. Management of the Bacou Group,
including our board of directors, was aware of these constraints and discussed
them from time to time at various board meetings. Additionally, because of the
existing capital structure of the Bacou Group, including the existing level of
debt, management of the Bacou Group, including Bacou USA, believed that the
Bacou Group, including Bacou USA, had limited access to additional debt
financing.

    In the second half of 1999, a representative of the Vandeputte family
contacted a representative of the Bacou family to express Vandeputte's desire to
sell its minority interest in Bacou S.A. The Bacou family realized that the
Bacou Group would need to raise additional capital or assist Vandeputte to find
a buyer for their interest, if the Bacou Group were to accommodate Vandeputtes'
desire to sell. The Vandeputte family is not and has not been affiliated in any
way with the Bacou family other than through a previous ownership interest in
Bacou S.A.

    From time to time the Bacou family has considered various alternatives with
respect to its investment in the Bacou Group, including a recapitalization, a
sale of all or part of the Bacou Group and a merger with another company.
Additionally, the Bacou family and the Bacou Group have, from time to time,
received unsolicited inquiries from third parties regarding the sale of all or
part of the Bacou Group, including one in 1999. The inquiries were general and
did not indicate prices at which the parties would intend to effect a
transaction. These proposals never advanced beyond very preliminary stages and
there were no meaningful discussions between any third party and any member of
the Bacou family or representative of the Bacou Group.

    The confluence of the capital constraints and the Vandeputte family's desire
for liquidity in 1999 caused the Bacou family to consider how best to capitalize
Bacou S.A. and Bacou USA to allow for both a liquidation of the Vandeputte
interest in Bacou S.A. and a continuation of its long-term strategy of building
a major global safety and security company. The Bacou family determined that
achieving both goals would require a substantial increase in the indebtedness of
Bacou S.A., Bacou USA, the Bacou family, or a combination thereof, or a
substantial dilution of the Bacou family's interest in Engineering Henri Bacou,
Bacou S.A. or Bacou USA. In light of these circumstances and the consolidation
trend described above, the Bacou family believed that there was substantial
value that a third party would attribute to the Bacou Group.

                                       20
<Page>
    In December 1999, senior management of Bacou S.A., including Philippe Bacou,
and Bacou USA met with the financial and legal advisors, Deutsche Banc Alex.
Brown and White & Case LLP, respectively, to the Bacou family and Bacou S.A. to
discuss, in general terms, the possibility of pursuing a sale or other strategic
transaction involving the Bacou Group. Among the issues discussed at that
meeting was the practice of Bacou S.A. not to obtain annual consolidated audited
financial statements prepared in accordance with U.S. GAAP. At that time,
Philippe Bacou was advised by the above financial and legal advisors that a sale
or merger transaction would be unlikely unless consolidated audited financial
statements were prepared in accordance with U.S. GAAP for the Bacou Group. As a
result of this meeting Bacou S.A. engaged KPMG S.A. as its independent auditors
and KPMG began preparing consolidated financial statements for the Bacou Group.

    During the first half of 2000, the Bacou family, acting through Philippe
Bacou, and Bacou S.A., engaged in periodic discussions with their financial and
legal advisors, Deutsche Banc Alex. Brown and White & Case LLP, respectively,
and with Bacou USA regarding strategic alternatives for the Bacou Group. In
particular, Messrs. Bacou, Stepan and Barr had several conversations in which
they concluded that, regardless of whether or not a transaction would be
proposed involving the sale of Bacou USA's publicly held shares of common stock,
it would be necessary to prepare a data room and provide potential buyers access
to the senior management of Bacou USA in order to participate in and support the
Bacou family's exploration of strategic alternatives for the Bacou Group.
Messrs. Bacou, Stepan and Barr anticipated that any potential buyer of Bacou
S.A. and the Bacou family interest in the Bacou Group would need to meet with
Bacou USA's senior management and investigate the business, operations and
financial condition of Bacou USA as part of its due diligence process, because
of the importance of Bacou USA to the Bacou Group. Because of the potential for
conflicts of interest between the Bacou family and the public stockholders of
Bacou USA inherent in a possible sale of the Bacou Group, Mr. Stepan and
Mr. Barr proposed to Mr. Bacou that, as a condition to the participation of
Bacou USA's management in the sale process, the Bacou family enter into an
agreement with Bacou USA to establish procedural safeguards to protect the
public stockholders of Bacou USA in connection with a possible sale of the Bacou
Group. The principal safeguards proposed by Messrs. Stepan and Barr were the
requirements that any transaction include an offer for the public stockholders
of Bacou USA at a price that would satisfy the oversight committee of the board
of directors and would be deemed fair by the oversight committee and its
financial advisors. The Bacou family agreed in principle with these basic
criteria, provided that the Bacou family would not be prevented from selling its
interest in Bacou S.A. Ultimately, in July 2000 the Bacou family entered into a
letter agreement regarding such procedures and this agreement is described
below.

    The Bacou family believed that Vandeputte's desire for liquidity interjected
an element of uncertainty into the evaluation of strategic alternatives for the
Bacou Group and that any sale or other strategic transaction involving Bacou
S.A. and Bacou USA would be simplified if the Bacou family could acquire control
of the 38% minority interest in Bacou S.A. held by Vandeputte. The Bacou family,
however, did not believe that it was in a position at that time to purchase the
Vandeputte shares on terms that would be acceptable to the Bacou family and
Vandeputte. In connection with exploring alternatives for simplifying the
ownership structure of Bacou S.A., Philippe Bacou, on behalf of the Bacou
family, sought the assistance of Bacou USA's management in structuring and
negotiating a transaction whereby the Bacou S.A. shares held by Vandeputte
either could be purchased by parties that the Bacou family believed would
support, as shareholders, a sale of Bacou S.A. or could be brought within the
control of the Bacou family without requiring the Bacou family or Bacou S.A. to
incur substantial debt to purchase the shares. Beginning in early 2000 and
lasting through early July 2000, our senior management, with Mr. Bacou's consent
and support, periodically engaged in discussions and negotiations with
representatives of Vandeputte regarding means of liquidating the Vandeputte
interest in Bacou S.A. in a manner consistent with the Bacou family's goals.
These discussions resulted in the execution, on July 8, 2000, of a Share Option
Purchase Agreement pursuant to which Protection Participation, Hobar Corporation
N.V. and Sauvegarde LLC received an irrevocable option to purchase all of the
shares of Bacou S.A. owned on such date by Mevra Beheer BV, an entity

                                       21
<Page>
controlled by Vandeputte International NV, representing 38% of Bacou S.A.'s
outstanding shares. Protection Participation is an entity managed by Philippe
Bacou, Sauvegarde is an entity owned by Messrs. Barr, Bennett, Hebert and
Stepan, our senior management, and Hobar Corporation is an entity unaffiliated
with Bacou USA, Bacou S.A., the Bacou family, Protection Participation and
Sauvegarde. The Share Option Purchase Agreement is discussed in more detail
under "SPECIAL FACTORS--Interests of Certain Parties in the Merger and Related
Acquisition Transactions; Potential Conflicts of Interest--Share Option Purchase
Agreement."

    On July 7, 2000, at a meeting of Bacou S.A.'s board of directors the Bacou
family discussed the Share Option Purchase Agreement and also determined to
explore strategic alternatives to enhance value for its shareholders and to
engage financial advisors specifically for that purpose.

    Following the meeting of Bacou S.A.'s board, there was a special telephonic
meeting of our board of directors on Friday, July 7, 2000. At this meeting,
Mr. Bacou, Co-chairman of our board of directors, explained the circumstances
described above which had led the Bacou family to contemplate the sale of the
Bacou Group. Mr. Bacou explained that the Bacou family had determined that it
would offer all or part of its interest in Bacou S.A. for sale. He further
explained that, because of the Bacou family's indirect control of Bacou USA
through its control of Bacou S.A., the Bacou family's interest in Bacou USA
would also be offered for sale. Mr. Walter Stepan, Co-chairman of our board of
directors, further explained that the Bacou family and Bacou S.A. would prefer
to offer the entire Bacou Group for possible sale. After a discussion of these
developments, our board of directors determined that the oversight committee of
the board of directors would review any transaction involving a sale of Bacou
USA. The oversight committee had been established in connection with Bacou USA's
initial public offering in 1996 to address potential conflicts of interest that
might arise between Bacou USA's public stockholders and Bacou S.A. The oversight
committee consists of Mr. Alfred J. Verrecchia and Mr. Karl F. Ericson, two
directors who are not employees or officers of any entity in the Bacou Group and
who are not otherwise affiliated with the Bacou Group, the Bacou family or
Christian Dalloz.

    At the July 7 meeting of our board of directors, Messrs. Stepan and Barr
described their prior discussions with Philippe Bacou concerning procedural
safeguards and the Bacou family's agreement in principle to enter into a letter
agreement regarding such procedures. Messrs. Stepan and Barr expressed their
concern that an acquirer of the Bacou family interest in Bacou S.A. would become
the controlling stockholder of Bacou USA and could engage in a transaction which
would eliminate the public minority stockholders of Bacou USA at a lower per
share value than such acquirer had paid for its indirect ownership interest in
Bacou USA. They therefore proposed to the board of directors that any sale of
the Bacou family interest in Bacou S.A. should include the stockholders of Bacou
USA, other than Bacou S.A. Mr. Barr then described a proposed draft letter
agreement to be entered into between the Bacou family and Bacou USA. The
principal term of the proposed letter agreement required that the Bacou family
not accept any offer for their interests in Bacou S.A. and Engineering Henri
Bacou unless such offer also contained an undertaking to offer to purchase the
shares of our common stock not owned by Bacou S.A. on similar terms as the
purchase of the Bacou S.A. shares. The board of directors discussed the draft
letter and authorized Mr. Stepan and Mr. Barr to continue negotiations with the
Bacou family regarding the letter agreement. The board of directors also
authorized management to engage Deutsche Banc Alex. Brown as financial advisors
to represent Bacou USA in connection with the potential sale of Bacou Group
through an auction process. The board of directors further authorized the
oversight committee to retain its own independent financial advisor and legal
advisor in connection with the oversight committee's review and consideration of
any potential sale transaction.

    On Monday, July 10, 2000, we issued a joint press release with Bacou S.A.
announcing that Bacou USA and Bacou S.A. would engage financial advisors to
explore strategic alternatives to enhance value for the shareholders of both
companies.

    Between July 10, 2000 and July 14, 2000, Mr. Stepan, Mr. Barr and Mr. Bacou
continued discussing and negotiating, together with their advisors, the specific
terms of the letter agreement. The

                                       22
<Page>
parties primarily discussed technical matters relating to the evaluation of bids
that might be received but the significant terms of the letter agreement did not
change materially as a result of these discussions. On July 14, 2000, we entered
into a letter agreement with the Bacou family whereby the Bacou family agreed
that, in connection with a possible sale of Engineering Henri Bacou and Bacou
S.A., they would not accept any offer for their interests in Engineering Henri
Bacou and Bacou S.A. (and thereby for their indirect ownership of our common
stock) unless such offer also contained an undertaking to offer to purchase the
shares of our common stock, not owned by Bacou S.A., on substantially similar
terms. In this letter agreement, it was also agreed that the oversight committee
of our board of directors would review any sale transaction involving Bacou USA
and that the oversight committee would retain its own independent financial
advisor, pursuant to which PaineWebber Incorporated was retained on August 21,
2000, and legal counsel, Edwards & Angell LLP, to assist them in such review, at
our expense.

    On July 14, 2000, we issued a press release announcing that the Bacou family
and Bacou USA each had separately engaged Deutsche Bank as their respective
financial advisors in connection with the exploration of strategic alternatives
for Bacou S.A. and Bacou USA. We also announced that we had entered into the
letter agreement with the Bacou family.

    FIRST STAGE OF THE AUCTION PROCESS

    During July and August 2000, with the consent of the Bacou Group, Deutsche
Bank contacted numerous potential acquirers of the Bacou Group and provided
limited information to determine whether such potential acquirers would be
interested in purchasing all of the Bacou Group. This limited information
included a two page summary which included information relating to the
description of the Bacou Group, its products, customers, facilities, investment
considerations, and information regarding 1999 sales and earnings for the Bacou
Group, Bacou USA and the European operations of Bacou S.A. The potential
acquirers were selected based on:

    - experience with acquisitions in similar or related markets;

    - strategic fit; and

    - perceived financial capability to complete an acquisition of the Bacou
      Group.

    A total of 87 of these parties, including Christian Dalloz, agreed to
execute confidentiality agreements and requested further information regarding
the Bacou Group. By early August, KPMG had completed its audit of the Bacou S.A.
financial statements for the 1999 fiscal year. On August 5, 2000, Deutsche Bank
distributed a confidential information memorandum regarding the Bacou Group to
the potential acquirers who had executed confidentiality agreements. The
confidential information memorandum described the business, operations and
prospects for the Bacou Group, information regarding results of operations for
the Bacou Group on both a historical basis and as adjusted to (1) give full-year
impact to mid-year acquisitions, (2) exclude certain expenses which were non-
recurring or would be eliminated in connection with a potential sale of the
Bacou Group, and (3) allow for comparability on a constant exchange rate basis,
and management's financial projections (prepared in July 2000) for each of Bacou
USA, the European operations of Bacou S.A., and the Bacou Group for fiscal years
2000 - 2003.

    The Bacou Group did not solicit offers for any or all of the separate
operations comprising the Bacou Group. The bid instructions given to prospective
buyers indicated that the principal objective was to sell the entire ownership
of the Bacou Group on terms that reflected the highest possible value, and that
no consideration would be given to expressions of interest that proposed the
separate divestiture or purchase of any individual asset, business, segment, or
other part of Bacou S.A. or Bacou USA. In addition, the shareholders of Bacou
S.A. were reluctant to consider a separate sale of Bacou USA because of the
potential for such a sale to result in adverse tax consequences to the
shareholders of Bacou S.A.

                                       23
<Page>
    On August 16, 2000, the oversight committee, acting by unanimous written
consent authorized the retention of PaineWebber Incorporated as its independent
financial advisor. The investment banking business of PaineWebber Incorporated
was subsequently combined with UBS Warburg following the merger of the parent of
PaineWebber Incorporated with an affiliate of UBS Warburg in November 2000.

    On September 1, 2000, Hobar Corporation, Protection Participation and
Sauvegarde exercised their respective options pursuant to the Share Option
Purchase Agreement and purchased an aggregate of 470,953 shares of Bacou S.A.
The exercise of the option required initial payments of 14 million French francs
($1,823,962), 7 million French francs ($911,981) and 14 million French francs
($1,823,962), by Hobar, Protection Participation and Sauvegarde, respectively.
These initial payments have become non-refundable despite the fact that if the
merger and the related sale of Bacou S.A. and Engineering Henri Bacou are not
completed, the option parties will be obligated to return the option shares to
Mevra Beheer. The Share Option Purchase Agreement requires that the option
parties make additional payments to Mevra Beheer upon the completion of the
merger and the related sale of Bacou S.A. to Christian Dalloz.

    In early to mid-September 2000, pursuant to a request to potential acquirers
for non-binding proposals regarding the purchase of the Bacou Group, Deutsche
Bank received non-binding written indications of interest in further exploring
an acquisition of all or part of the Bacou Group from a total of 27 potential
acquirers. These interested parties did not include Christian Dalloz, which
indicated that it would not participate in the auction process since it was not
interested in an all cash purchase of the Bacou Group. However, Christian Dalloz
indicated that it would be interested in a combination of a cash and stock
transaction. Of the indications received, eighteen were received from private
equity funds, five were received from companies that either participated in the
personal protection industry or allied product markets, one expressed an
interest in specific parts of Bacou USA and Bacou S.A. without specifying any
value, one expressed an interest in the European operations of Bacou S.A.
without specifying any value, and two expressed an interest for specific parts
of Bacou S.A. only. The range of values in the 23 indications of interest for
the entire Bacou Group was $610 million to $1 billion and the range of values
for Bacou USA were $585 million to $776 million, or approximately $25.00-$35.00
per Bacou USA common share. These ranges reflected enterprise values, which
include equity and debt net of cash and cash equivalents. Each of the
indications of interest was based on limited information and subject to
significant conditions.

    On September 15, 2000, members of our senior management and the senior
management of Bacou S.A. met with representatives of Deutsche Bank to review the
preliminary indications of interest received from the potential acquirers.
Deutsche Bank identified the parties who had returned indications of interest,
described their proposals, discussed their previous experience in similar types
of acquisitions and the value of the preliminary indications of interest. The
material information provided by Deutsche Bank reflected the range of values
indicated above. Deutsche Bank also expressed its assessment of each party's
level of interest and ability to complete a transaction from a financial and
regulatory perspective.

    As a result of these discussions, the senior management teams of Bacou S.A.
and Bacou USA agreed to provide further due diligence opportunities to nine
parties from whom Deutsche Bank had received non-binding written initial
indications of interest in acquiring the Bacou Group. The parties chosen by the
Bacou Group were based on management's assessment of the information and report
by Deutsche Bank as described above. The Bacou Group received one indication of
interest from a party, which if consummated on its proposed terms, would have
yielded higher values for the Bacou Group than other offers received and
accepted for further review and diligence. The Bacou Group believed that the
nature of this bidder's business could pose significant antitrust impediments to
a transaction which would either prevent the transaction or require an antitrust
remedy (such as divestitures) that would substantially reduce the benefits of
the transaction to the bidder. This party's indication also included a material
financing condition, including the availability of sufficient equity and debt
financing

                                       24
<Page>
to accomplish the transaction on the terms indicated. The interested party
competes directly with Bacou USA in several key product markets. Based on
personal protection product market surveys by Frost & Sullivan, a widely
recognized third party source of industry information, Bacou USA believed that a
potential combination of Bacou USA's operations in certain key product markets
with those of the bidder's would raise the combined company's market share in
such markets to a level which would be unacceptable to U.S. antitrust
regulators. The interested party is a highly leveraged privately owned company,
and therefore, a potential transaction for the Bacou Group would have involved
significant private equity as well as additional borrowing by the interested
party. The Bacou Group believed that the antitrust considerations coupled with a
general deterioration in the capital markets significantly reduced the
likelihood of completing the proposed transaction at the proposed pricing.
Although the Bacou Group solicited assurances from this bidder that these
antitrust concerns would not impede or delay completion of a transaction or
result in a reduced purchase price, this bidder was unwilling to provide any
satisfactory assurances in this regard and was unwilling to proceed with a
limited data review to enable the parties to better understand the antitrust
risk. Consequently, the Bacou Group determined not to engage in additional
discussions with this bidder.

    On September 19, 2000, Deutsche Bank offered to the nine remaining
interested parties interested parties the opportunity to perform further due
diligence on the Bacou Group and to meet with management of Bacou S.A. and Bacou
USA. Bacou S.A. and Bacou USA established data rooms containing detailed
information at the offices of White & Case LLP in Paris and New York.

    On September 21, 2000, the oversight committee held a meeting to discuss the
status of the sale process for the Bacou Group. Also present at the meeting
were: representatives of the law firm of Edwards & Angell LLP, counsel to the
oversight committee; representatives of Deutsche Bank, financial advisors to the
Bacou family and Bacou USA; and representatives of the oversight committee's
independent financial advisor, PaineWebber Incorporated (who participated by
telephone). At the request of the oversight committee Deutsche Bank
representatives reviewed the same information earlier reviewed with the senior
management of Bacou USA and Bacou S.A., as described above. Deutsche Bank
representatives discussed with the oversight committee the status of the auction
process. Deutsche Bank reviewed the various indications of interest from
potential acquirers of the Bacou Group and generally discussed the strengths and
weaknesses of various interested parties and potential transaction structures
such as structuring the transaction as a recapitalization. The oversight
committee also discussed with its advisors various legal issues relating to the
auction process including legal documentation that might be required and
potential antitrust approvals that might be required. After completing its
review of the indications of interest, Deutsche Bank's presentation, and
discussing the auction process with its advisors, the oversight committee
accepted the recommendation of Deutsche Bank and the senior management of Bacou
USA and Bacou S.A. to invite certain parties to continue due diligence.
Throughout the auction process, Bacou S.A., our senior management and our
financial and legal advisors periodically updated the oversight committee with
respect to the auction process which was directed by the Bacou family.

    Between September 25, 2000 and October 27, 2000, the interested parties
conducted additional documentary due diligence in the data rooms. Additionally,
during this period, they attended presentations by senior managers of Bacou S.A.
and Bacou USA and visited certain manufacturing facilities in the United States,
Mexico and in Europe to obtain additional information regarding the business and
operations of Bacou S.A. and Bacou USA. The presentations included reports by
the senior management of each of Bacou USA and Bacou S.A. describing the
organization, history, products, operations, marketing and sales strategies,
customers, and historical and projected financial information for each of Bacou
USA and Bacou S.A. The financial information presented was the same information
as provided in the confidential information memorandum previously distributed to
them. The interested parties were invited to ask questions of management to
clarify any information provided in the presentation.

                                       25
<Page>
    On October 19, 2000, the oversight committee held a meeting to discuss the
status of the sale process and to review a draft merger agreement that Bacou USA
proposed to deliver to potential acquirers with respect to the potential
acquisition of Bacou USA as part of an overall sale of the Bacou Group. Also
present at the meeting were Mr. Barr and Mr. Winfield Major, General Counsel of
Bacou USA. Representatives of the oversight committee's legal advisors and
independent financial advisors (who participated by telephone) were also present
at the meeting. Mr. Barr informed the oversight committee about the status of
the auction process. The oversight committee had received the draft merger
agreement that Bacou USA intended to deliver to potential acquirers. The
oversight committee's legal advisors described the principal features of the
draft merger agreement. The oversight committee's financial and legal advisors
indicated that they would continue reviewing draft documentation and
periodically update the oversight committee with respect to important issues
related to the auction process.

    On November 5, 2000, Deutsche Bank sent out letters requesting final offers
from bidders.

    On November 21, 2000, in response to written and telephonic requests from
Deutsche Bank, two interested parties delivered to Deutsche Bank revised
proposals to purchase the Bacou Group. Between November 21 and December 15,
2000, Bacou S.A., Bacou USA and their financial and legal advisors had several
meetings and telephone calls to discuss the proposals, and Deutsche Bank
continued to solicit proposals from participants in the auction process.

    On December 15, 2000, we issued a press release announcing that, although
progress had been made in the evaluation of strategic alternatives for Bacou
S.A. and Bacou USA, the evaluation process would not be completed until some
time in January 2001. We also announced that we continued to expect the process
to result in a sale of the businesses of Bacou S.A. and Bacou USA in their
entirety to one purchaser in a single transaction.

    Following receipt of the proposals on November 21, 2000, Bacou S.A. and
Bacou USA together with Deutsche Bank engaged in further discussions and
negotiations with two remaining potential acquirers in an effort to induce them
to improve their proposals. By January 15, 2001, Deutsche Bank had received
modified offers to purchase the entire Bacou Group with values ascribed to the
publicly held shares of Bacou USA of up to $25 per share in cash. Each offer was
subject to material conditions, including continued due diligence, negotiation
of definitive agreements, the availability of financing and a period of
exclusivity to complete the transaction. Neither potential transaction contained
a material risk regarding antitrust approvals. The revised valuations reflected
the detailed diligence efforts undertaken by the two interested parties since
the submission of their initial proposals. Based on conversations with the final
bidders, Bacou USA believes that the revised valuations also reflected the
assessments by the interested parties of the changes in the general industry and
capital market conditions since the submission of their initial proposals. As
the two proposals were the result of an exhaustive auction process, the Bacou
Group did not resolicit bids at this point.

    From the end of November, 2000 until mid-January, 2001, representatives of
Bacou S.A. and its financial and legal advisers had a number of meetings and
discussions in France with representatives of Christian Dalloz and its financial
and legal advisors. Although Christian Dalloz decided not to participate in the
auction process because it was not interested in an all cash transaction, the
Bacou family decided to continue discussions with Christian Dalloz because based
on its verbal indication of interest to Philippe Bacou, it appeared that
Christian Dalloz's proposal, although not solely in cash, might be superior to
the offers received in the auction process. Christian Dalloz' verbal indication
of interest did not contain specific price terms for the transaction but implied
an enterprise value for the Bacou Group based on a range of multiples which
Mr. Bacou believed could yield a higher value to the Bacou Group stockholders
than the offers received in the auction process, in part because there may have
been tax advantages from doing a transaction with a French purchaser. The
parties had meetings at the offices of Rothschild & Cie, Christian Dalloz'
financial advisors, on November 28, December 4, December 12, December 14, 2000
and January 9, 2001. At these meetings, representatives of Christian Dalloz made
various proposals regarding a possible combination with the Bacou Group. All of
the

                                       26
<Page>
proposals contained price terms based on the enterprise value of the Bacou Group
and the January 9 presentation by Christian Dalloz contained a $25 per share
price for the publicly held shares of Bacou USA. The deal structures proposed
included a merger with Bacou USA and generally reflected the deal structure
ultimately agreed to by the parties. At these meetings the parties discussed
general deal structures, financing, regulatory approvals required and valuation
issues.

    On January 15, 2001, Mr. Barr delivered to the financial advisors to the
oversight committee and the members of the oversight committee detailed
information regarding two of the proposals, which did not include the Christian
Dalloz proposal, that were initially received on November 21, 2000 and which
were under consideration by the Bacou family, Bacou S.A. and Bacou USA. The
information provided to the oversight committee and their financial advisors
included comparisons prepared by the management of Bacou USA of the financial
terms of the two competing proposals to acquire the Bacou Group.

    On January 17, 2001, the Bacou family and Bacou S.A. determined that they
would negotiate exclusively with only one potential acquirer and would attempt
to reach agreement on definitive documentation for the sale of the Bacou Group
and, therefore, granted exclusivity to the potential acquirer other than
Christian Dalloz. Based on the Bacou family's own analysis, the views of the
senior management of Bacou S.A. and Bacou USA and after considering the advice
of the Bacou Group's legal and financial advisors, the party was selected on the
basis of superior financial terms relative to the other proposal submitted,
certainty of financing, low risk relative to obtaining antitrust approvals, and
potential synergies resulting from the combination. Between January 17, 2001 and
February 8, 2001, Bacou S.A. and Bacou USA together with the legal and financial
advisors to Bacou S.A., engaged in intensive negotiations and discussions with
the potential acquirer to finalize the legal documentation for a sale of the
Bacou Group, including a merger agreement providing for the acquisition of Bacou
USA. The potential acquirer also engaged in additional legal and business due
diligence during this period. In connection with these negotiations, the
potential acquirer had proposed to Bacou S.A. that the public stockholders of
Bacou USA receive $25 in cash per share as consideration for their shares of
Bacou USA in the merger. The members of the oversight committee and the
committee's legal and financial advisors were periodically updated throughout
this period regarding the status of the discussions. Throughout these
negotiations the valuation attached to the shares of the public stockholders of
Bacou USA offered by such potential acquirer did not change from the $25 cash
per share price. As described below, due to the subsequent termination of
discussions with such potential acquirer on February 8, there was no further
negotiation with respect to the purchase price to be paid for shares of Bacou
USA held by the public shareholders.

    The oversight committee met on February 1, 2001. Mr. Major was present by
invitation, as were representatives of Edwards & Angell LLP and UBS Warburg LLC,
the oversight committee's legal and financial advisors, respectively. At this
meeting the oversight committee engaged in a detailed discussion with its legal
and financial advisors of the status of the auction process and the status of
the negotiations with the potential acquirer. The UBS Warburg LLC representative
indicated to the oversight committee, based on a review of information provided
by Deutsche Bank, that the auction process conducted by the Bacou Group and its
financial advisors had been thorough and designed to reach the maximum number of
potential bidders. UBS Warburg LLC also explained the components of the then
proposed consideration to be received by the stockholders of the Bacou Group.
UBS Warburg LLC discussed with the oversight committee the $25 per share cash
consideration proposed to be paid to the stockholders of Bacou USA other than
Bacou S.A., and the oversight committee determined that $25 per share would be
inadequate. The oversight committee's determination that the proposed $25 per
share cash consideration was inadequate was based on the ranges of values
indicated through the auction process, its own general knowledge of Bacou USA's
business, operations and prospects, and the oversight committee's review of UBS
Warburg LLC's presentation at the February 1, 2001 meeting and discussions with
UBS Warburg LLC. For a summary of UBS Warburg LLC's preliminary valuation
analysis presented at the February 1, 2001 oversight committee meeting, see
"OTHER MATTERS--

                                       27
<Page>
Preliminary Materials Prepared by UBS Warburg LLC." The closing price for the
shares of Bacou USA on the previous trading day was $26.64 per share. The
oversight committee instructed UBS Warburg LLC to meet with Deutsche Bank to
explain the oversight committee's position with a view to seeking an increase in
the proposed merger consideration. Subsequent to this meeting, on February 1,
2001, UBS Warburg LLC met with Deutsche Bank twice and discussed with Deutsche
Bank the oversight committee's views regarding the $25.00 per share offered by
the potential acquirer but did not reach any resolution on what would be an
appropriate price. UBS Warburg LLC later reported back to the oversight
committee regarding these discussions.

    Our board of directors met on February 2, 2001 with all directors other than
Christophe Bacou present. Additionally, the following officers of Bacou USA were
present: Mr. Bennett; Mr. Hebert; and Mr. Major. Additionally, representatives
of Edwards & Angell LLP, counsel to the oversight committee, representatives of
Deutsche Bank, financial advisors to Bacou S.A. and Bacou USA; and
representatives of White & Case LLP, counsel to Bacou S.A., were present at the
meeting. Mr. Barr and Mr. Stepan discussed with the board of directors certain
financial information related to Bacou USA and its operating units for the
fourth quarter and year ended December 31, 2000. The board of directors,
including the members of the oversight committee, then engaged in a discussion
regarding the auction process with respect to the Bacou Group. The Deutsche Bank
representatives discussed with the board the auction process that had been
undertaken with respect to the sale of the Bacou Group and the status of
negotiations with the potential acquirer. The Deutsche Bank representatives
engaged in a detailed discussion with the board of directors of the significant
structural and economic features of the transaction being proposed by the
potential acquirer. They responded to numerous questions and issues raised by
members of the board of directors and, in particular, by members of the
oversight committee, related to the financial and structural terms of the
proposal. The Deutsche Bank representatives also reviewed certain financial and
comparative valuation analyses. Thereafter, the White & Case representatives
discussed with the board their fiduciary duties under Delaware law in connection
with considering any proposed transaction. The White & Case representatives
discussed the significant features of the existing draft of the merger
agreement, emphasizing that the oversight committee's independent financial
advisor would have to provide an opinion to the oversight committee regarding
the fairness from a financial point of view of the consideration being provided
to the public stockholders of Bacou USA as a condition to executing any merger
agreement. The representative of Edwards & Angell indicated that his law firm
had been working together with White & Case in the negotiations regarding the
merger agreement. The board of directors, including the oversight committee,
then engaged in a discussion, together with the legal and financial advisors
present at the meeting, of a number of the significant features of the proposal.
For a description of the Deutsche Bank presentation at the February 2, 2001
board meeting, see "OTHER MATTERS--Presentation by Deutsche Bank at the
February 2, 2001 Bacou USA Board Meeting with Respect to the Then Proposed
Transaction with a Potential Acquirer."

    Prior to reaching agreement on the principal transaction terms, on
February 8, 2001 the potential acquirer terminated negotiations with respect to
the potential purchase of the Bacou Group because the potential acquirer was
unable to successfully conclude discussions with a potential equity financing
source. The oversight committee was promptly informed of this development.

    NEGOTIATIONS WITH CHRISTIAN DALLOZ

    Following the termination of the auction discussions, Philippe Bacou
contacted Christian Dalloz to indicate that the period of exclusivity for
negotiations with the potential acquirer had terminated and that the
shareholders of Bacou S.A. could consider proposals for an acquisition of the
Bacou Group.

    On February 9, 2001, Christian Dalloz delivered to Bacou S.A. a draft
non-binding letter of intent for the purchase of the Bacou Group, including
Bacou USA. The draft letter of intent provided aggregate consideration to be
paid for the entire Bacou Group but did not allocate the aggregate value between
Bacou USA and the remainder of the Bacou Group and did not propose a price to be
paid to

                                       28
<Page>
the public stockholders of Bacou USA. The draft letter of intent indicated that
the portion of the aggregate consideration to be paid for the shares of Bacou
USA would be determined through good faith negotiations between the parties with
a view to obtaining the approval of the oversight committee of Bacou USA.
Christian Dalloz conditioned the continuation of negotiations on a termination
of the Bacou Group's auction process but this proposal was rejected by the Bacou
Group.

    Following the termination of negotiations with the potential acquirer and
the termination of the exclusivity agreement related thereto, Deutsche Bank and
members of Bacou S.A.'s and Bacou USA's management had discussions with
previously interested parties regarding the possibility that such parties would
make revised offers to purchase the Bacou Group. No interested party proposed
terms that were superior to those offered by Christian Dalloz, nor did any
proposal contain a per share offer greater than $25 for the public stockholders
of Bacou USA.

    In February and March 2001, Christian Dalloz, together with its French legal
advisors, Bredin Pratt, U.S. legal advisors, Cravath Swaine & Moore, and
financial advisors, Rothschild & Cie conducted a business and legal due
diligence investigation of the Bacou Group. The Bacou Group, together with their
legal and financial advisors, simultaneously conducted a business and legal due
diligence investigation of Christian Dalloz. During this time the
representatives of Christian Dalloz were provided with financial projections for
Bacou USA. These projections are set forth below under "SPECIAL FACTORS--Our
Analysis of Future Performance." The due diligence investigations included the
following:

    - February 22, 2001--meeting between Mr. Claude Balleyguier, Chief Executive
      Officer of Christian Dalloz, and Philip Barr at the principal executive
      offices of Bacou USA to discuss general management issues including
      potential roles for management of Bacou USA following the merger;

    - February 27, 2001--Bacou USA senior management made a presentation
      regarding the business and operations of Bacou USA to Christian Dalloz'
      senior management, financial advisors, legal advisors and potential
      financing sources and conducted a tour of the Uvex facility in Smithfield,
      Rhode Island;

    - March 5, 2001--Mr. Barr and Mr. Hebert met with Mr. Balleyguier and
      Mr. de la Morandiere, Chief Financial Officer of Christian Dalloz,
      regarding potential commercial benefits of the combination of the Bacou
      Group and Christian Dalloz;

    - Numerous dates--representatives of Christian Dalloz and the Bacou Group
      and their financial and legal advisors conduct due diligence at the data
      rooms established for this purpose;

    - March 6, 2001--senior management of Bacou S.A. made a presentation
      regarding the business and operations of Bacou S.A. to senior management
      of Christian Dalloz and their financial advisors, legal advisors and
      potential financing sources at the offices of Rothschild in Paris, France;
      and

    - March 10 and 11, 2001--senior management of Bacou S.A., Bacou USA and
      Christian Dalloz engaged in discussions for the purpose of identifying
      potential commercial benefits from the combination of the Bacou Group and
      Christian Dalloz.

    On March 14, 2001 senior management of Christian Dalloz met with senior
management of Bacou S.A. and Bacou USA together with the respective financial
and legal advisors of Christian Dalloz and Bacou S.A., at the offices of
Rothschild in Paris, France. At this meeting the parties engaged in negotiations
regarding significant terms for a combination of the Bacou Group and Christian
Dalloz. In particular, the parties focused on the relative equity values of
Christian Dalloz and the Bacou Group as well as the payment of expenses related
to the transaction. These discussions continued on March 15, 2001 with the same
parties represented.

    As a result of these meetings, a revised draft of a non-binding letter of
intent was delivered by Christian Dalloz' French legal advisors to the Bacou
Group and its financial and French legal advisors.

The Bacou Group and its financial and French legal advisors engaged in frequent
discussions and negotiations with Christian Dalloz and its financial and French
legal advisors between March 15 and March 23, 2001 with respect to the terms of
the draft non-binding letter of intent. On March 22 and 23, 2001,
representatives of the Bacou Group, including Mr. Philippe Bacou, and their
financial and French legal advisors met with representatives of Christian Dalloz
and its financial and French legal advisors at the offices of Christian Dalloz'
financial advisors in Paris to continue these discussions. In addition to
discussing the drafting of the letter of intent, during these discussions the
parties focused on financing issues, regulatory approvals that might be
required, means of providing liquidity for the Christian Dalloz shares that
would be issued to the Bacou family in the sale of Bacou S.A. and Engineering
Henri Bacou and transaction expenses. As a result of these meetings and
discussions the parties agreed on the general terms of a non-binding letter of
intent by and among Mr. Philippe Bacou on behalf of the Bacou family, and the
significant minority stockholders of Bacou S.A., Hobar, Protection Participation
and Sauvegarde. The non-binding letter of intent was then executed as of
March 24, 2001. On that same date the parties entered into an exclusivity
agreement pursuant to which the Bacou family agreed to negotiate exclusively
with Christian Dalloz regarding any potential sale of the Bacou Group.

    The non-binding letter of intent described certain significant terms for a
potential combination of the Bacou Group and Christian Dalloz. The non-binding
letter of intent contemplated the general transaction structure that was
ultimately reflected in the definitive transaction documents for the merger and
the related acquisitions of Bacou S.A. and Engineering Henri Bacou. The
non-binding letter of intent expressed a principle that the total equity value
of the Bacou Group was three times the total equity value of Christian Dalloz
and that the value attributable to each Christian Dalloz share to be issued in
exchange for certain shares of Bacou S.A. and Engineering Henri Bacou would be
78.6 Euros. The non-binding letter of intent did not establish any price to be
paid for the public stockholders of Bacou USA. Instead, the value attributable
to such shares was left to be negotiated by the parties to the non-binding
letter of intent with a view to obtaining the favorable recommendation of such
price by the oversight committee. Although no price was assigned for the public
stockholders of Bacou USA in the non-binding letter of intent, Bacou S.A. had
informed Christian Dalloz that the oversight committee had previously rejected
as inadequate a per share cash purchase price of $25 for the Bacou USA stock.

    The oversight committee met on March 27, 2001. The committee members,
Mr. Barr and Mr. Hebert were present in person and Mr. Walter Stepan was present
by telephone. Messrs. Stepan, Barr and Hebert provided a summary of the
developments regarding the evaluation of strategic alternatives by the Bacou
family, Bacou S.A. and Bacou USA. This report supplemented the periodic updates
that Mr. Barr had provided to the members of the oversight committee by means of
telephone calls during the period between March 5 and March 23, 2001. At the
oversight committee meeting, Mr. Barr described the material terms of the
proposed combination between the Bacou Group and Christian Dalloz as outlined in
the non-binding letter of intent. Mr. Barr indicated to the oversight committee
that the proposal contemplated the purchase for cash of all the publicly held
shares of Bacou USA for an amount to be determined. The oversight committee and
Messrs. Stepan, Barr and Hebert all acknowledged that the oversight committee
had earlier indicated in connection with the negotiations with an earlier
potential acquirer that, in the oversight committee's view, a price of $25 per
share in cash for the public stockholders of Bacou USA would be inadequate.

    Between March 24, 2001 and April 20, 2001 the Bacou Group, including
management of Bacou USA, and Christian Dalloz, together with their respective
legal and financial advisors, conducted additional business and legal due
diligence investigations of each other and began to prepare and negotiate the
transaction documentation related to the proposed combination of the Bacou Group
and Christian Dalloz. These activities involved frequent discussions by and
among the parties and their respective financial and legal advisors throughout
this period. On April 17, 2001, Christian Dalloz' legal counsel delivered to the
Bacou Group's legal counsel an initial draft of the merger agreement.

                                       30

    During the discussions with Christian Dalloz in March, Messrs. Barr, Stepan,
Hebert and Bennett came to the conclusion that, notwithstanding the terms of the
letter of intent, Christian Dalloz would ultimately seek a reduction in the
purchase price for the entire Bacou Group. Their belief was based on
conversations in which representatives of Christian Dalloz expressed
disappointment with the Bacou Group's actual operating performance in early
2001. Messrs. Barr, Stepan, Hebert and Bennett were concerned that such a
reduction in the purchase price for the Bacou Group would, in turn, reduce the
proceeds to Sauvegarde from the sale of Sauvegarde's Bacou S.A. shares. During
the evening of March 23, 2001 and on March 24, 2001, Messrs. Barr, Stepan and
Hebert met with representatives of Vandeputte in Belgium to open discussions
concerning the possible reduction of price by Christian Dalloz and Sauvegarde's
desire for a potential reduction of the remaining payments relating to the
exercise of the option under the Share Option Purchase Agreement. The Vandeputte
family agreed to an aggregate reduction equal to approximately 110,000,000
French francs ($14,331,127) in light of the expected adjustment to be made by
Christian Dalloz and as consideration for receiving cash payment for the shares
as opposed to a combination of cash and shares of Christian Dalloz.
Additionally, one of the Vandeputte shareholders agreed to a further reduction
in the price payable for such shareholder's shares equal to 6,814,786 French
francs ($887,851) as consideration for being paid in full sooner than was
otherwise required by the Share Option Purchase Agreement. Accordingly, the
parties to the Share Option Purchase Agreement executed an amendment thereto in
April 2001 to effect a reduction in the total purchase price for the option from
960,000,000 French francs ($125,071,656) to 843,185,214 French francs
($109,852,678) in the aggregate and to extend the time by which a sale of the
Bacou Group could occur before Sauvegarde, Protection Participation and Hobar
Corporation would be required to return to Mevra Beheer the Bacou S.A. shares
that they had purchased pursuant to the Share Option Purchase Agreement and
forfeit their deposit.

    On April 25, 2001, representatives of the Bacou Group, including management
of Bacou USA, met with representatives of Christian Dalloz at the offices of
Christian Dalloz' financial advisors in Paris to discuss, together with the
financial and French legal advisors for Christian Dalloz and the financial and
French legal advisors for the Bacou Group, certain issues arising out of the due
diligence investigations conducted to date. Additionally, the parties discussed
certain economic and structural issues related to the sale of Bacou S.A. and
Engineering Henri Bacou. This meeting continued on April 26, 2001.

    Throughout May, 2001 the financial and legal advisors to Bacou USA and
Christian Dalloz continued meeting and engaging in frequent discussions and
negotiations regarding the definitive documentation for the combination of the
Bacou Group and Christian Dalloz, including the merger agreement and the related
sale of Bacou S.A. and Engineering Henri Bacou. During this time the parties
also discussed the letter agreement which had been entered into by Bacou USA and
the Bacou family in connection with the first stage of the auction process. The
Bacou family and Bacou USA recognized that the letter agreement had originally
been intended to apply to the first stage of the auction process that ended
without a viable transaction. The Bacou family, Bacou USA and Christian Dalloz
also understood that the oversight committee would have to approve the proposed
merger (including the merger consideration) and determine that it was fair to
the unaffiliated stockholders of Bacou USA before the merger agreement could be
signed. Therefore, in order to facilitate the terms of the merger, Bacou USA,
without objection by the oversight committee, and the Bacou family mutually
agreed to terminate the letter agreement with effect on May 29, 2001.
Consequently, the letter agreement was not applicable to the merger.

    Throughout this period, the oversight committee and its legal and financial
advisors were periodically updated regarding the status of negotiations for the
sale of the Bacou Group and were aware that the parties might be in a position
to reach agreement by the end of the month. Consequently, on May 8, 2001, the
oversight committee met with its financial and legal advisors to discuss the
potential value to be received by the public stockholders of Bacou USA in the
merger. At this meeting, the oversight committee concluded that it still
believed that a $25.00 per share price for the public stockholders of Bacou USA
would be inadequate. Following such meeting the oversight

                                       31
<Page>
committee's legal advisors and Mr. Barr had a telephone discussion regarding the
results of the oversight committee's meeting during which the legal advisors
indicated to Mr. Barr the oversight committee's preliminary views as to
valuation for the shares of Bacou USA held by stockholders other than Bacou S.A.

    On May 8, 2001, Bacou USA received an unsolicited proposal from the previous
potential purchaser for the purchase of the Bacou Group with a value proposed
for the public stockholders of Bacou S.A. remaining at $25.00 per share. We did
not pursue this offer because the oversight committee had previously indicated
that a price of $25.00 per share in cash would be inadequate and because we were
bound by an exclusivity agreement with Christian Dalloz.

    Between May 8 and May 29, the legal representatives of Christian Dalloz, the
Bacou Group and the oversight committee submitted comments and engaged in
frequent discussions relating to the merger agreement.

    On May 9, 2001 Deutsche Bank, as financial advisor to the Bacou family,
delivered a letter to the oversight committee and its financial advisor
proposing that the stockholders of Bacou USA, other than Bacou S.A., be paid
$27.00 per share in cash as consideration for their shares in the merger. Prior
to this time, no proposals or counter proposals were made for the price to be
paid for the publicly held shares of Bacou USA because all prior negotiations
with Christian Dalloz focused on the total enterprise value of the Bacou Group.

    On May 14, 2001, the oversight committee met with Mr. Barr, Mr. Hebert,
Mr. Major and by conference telephone with the financial advisor and U.S. legal
advisor to the Bacou Group and the legal and the financial advisor to the
oversight committee. During this meeting Mr. Barr described the background and
status of the negotiations between the Bacou Group and Christian Dalloz. He
explained that during the course of the discussions with Christian Dalloz,
Christian Dalloz expressed the desire that the senior management of Bacou USA
continue in significant roles following the merger without proposing that the
transaction be conditioned on Bacou USA's management remaining with Bacou USA or
with the entity resulting from the global transaction. Mr. Barr also described
in detail the various interests of Messrs. Barr, Bennett, Hebert and Stepan in
the merger and the related sale of Bacou S.A. and Engineering Henri Bacou.
Mr. Barr described and quantified the following (based on the assumptions of
price for Bacou USA shares of $28.00 and Bacou Group total enterprise value of
$806,000,000): cash payments that would be owing to each of these individuals
upon completion of a merger under the change of control provisions of their
various employment contracts aggregating $5,300,000; the value of existing stock
options attributable to these executives if the merger and the related sale of
Bacou S.A. and Engineering Henri Bacou would be completed aggregating $6,892,500
(including the spread for the ungranted 2000 stock options at the proposed
price); the net profit to be realized by Sauvegarde for Bacou S.A. shares
Sauvegarde had purchased pursuant to the Share Option Purchase Agreement
aggregating $24,179,781; and an understanding between Philippe Bacou and
Messrs. Barr, Bennett, Hebert and Stepan pursuant to which the Bacou family
would make certain payments out of the proceeds of the sale of its shares of
Bacou S.A. and Engineering Henri Bacou to these individuals in recognition of
the important role that they had played in structuring and negotiating the sale
of the Bacou Group and their continued participation in the management of the
combined group aggregating $15,000,000. Mr. Barr also explained that, unlike the
exercise price in respect to the 2001 and 2002 options which was provided for in
the employment agreements, the exercise price on an aggregate of 125,000 stock
options for Messrs. Barr, Bennett, Stepan and Hebert to be granted in respect of
the 2000 performance of Bacou USA pursuant to their employment agreements had
not previously been determined. Mr. Barr proposed an exercise price for such
options based on the trading price of Bacou USA's shares prior to our
announcement in July 2000 that we would explore strategic alternatives. During
this meeting the oversight committee indicated its concern regarding the
exercise prices of the 2000, 2001 and 2002 options and the aggregate value of
the cash payments to which the four executives would be entitled from these
various arrangements as a result of the completion of the merger and the related
sale of Bacou S.A. and Engineering Henri Bacou. The

                                       32
<Page>
oversight committee's concern was based on its belief that the aggregate
payments described above were disproportionate to the size of the transaction
and, especially in the case of the payments pursuant to the understanding with
the Bacou family unacceptably increased the potential conflict of interest
between these individuals and the public stockholders of Bacou USA.

    On May 15, 2001, Christian Dalloz and its financial and French legal
advisors met with representatives of the Bacou Group, including management of
Bacou USA, and its financial and French legal advisors at the offices of
Rothschild in Paris to discuss the terms of the sale of the shares of Bacou S.A.
and Engineering Henri Bacou and other issues arising out of the joint due
diligence investigations. The parties agreed that for purposes of determining
the value of the Bacou Group, the value of Christian Dalloz shares would be
multiplied by 77 Euro instead of 78.6 Euro. This created a lower equity value
for Christian Dalloz which, applying the three-to-one valuation ratio that had
been agreed upon in the non-binding letter of intent, would, in turn, decrease
the equity value of the Bacou Group. The reduction in equity value for the Bacou
Group was attributed to further due diligence findings by Christian Dalloz and a
review of the Bacou Group's actual earnings and cash flow performance through
December 31, 2000. The parties reconvened at the offices of Christian Dalloz'
legal advisors on May 16, 2001 to engage in further discussions and negotiations
with respect to the sale of Bacou S.A. and Engineering Henri Bacou.

    Between May 17, 2001 and May 25, 2001, the oversight committee and its legal
advisors engaged in frequent discussions with Messrs. Stepan, Barr and Hebert
regarding the merger consideration for our stockholders other than Bacou S.A.
and the cash payment arrangement with the Bacou family and the pricing of the
options. During these discussions the oversight committee insisted that the
executives waive their right to the options to which they were entitled under
their respective employment agreements and agree not to accept the cash payments
that the Bacou family had agreed to make pursuant to the understanding reached
previously with the Bacou family. The executives insisted that the options were
provided by their employment agreements and that the cash payments to be made by
the Bacou family were to be made out of the proceeds received by the Bacou
family for the sale of their interests in Bacou S.A. and Engineering Henri Bacou
and that the Bacou family was entitled to distribute such proceeds in any manner
that it saw fit. Nevertheless, on May 23, 2001 the executives agreed to the
oversight committee's position and waived any right that they may have to
receive the options under their employment agreements and further agreed not to
accept any payments pursuant to the understanding reached with the Bacou family.
This agreement was communicated to the oversight committee by Mr. Stepan and
Mr. Barr in a telephone call to the oversight committee's legal advisor on
May 23, 2001.

    Additionally, during late May, 2001, Messrs. Barr, Bennett, Hebert and
Stepan discussed with Christian Dalloz the possible terms of new employment
agreements (and in the case of Mr. Stepan, a new consulting agreement) that they
expect to execute with Christian Dalloz upon completion of the merger. Although
no agreements with Christian Dalloz have been reached, the executives are
discussing with Christian Dalloz the possibility of entering into new employment
agreements (and a consulting agreement for Mr. Stepan) upon completion of the
merger which would provide for certain up-front payments representing signing
bonuses, guaranteed bonuses for 2001, and payments for non-competition and
non-solicitation agreements. Based on the current preliminary understanding
between Messrs. Barr, Bennett, Hebert, Stepan and Christian Dalloz, the value of
these payments under such future employment agreements and, with respect to
Mr. Stepan, consulting agreement, would be $4,240,000 in the aggregate and
$1,500,000, $1,200,000, $1,200,000 and $340,000 for each of Mr. Barr,
Mr. Bennett, Mr. Hebert and Mr. Stepan, respectively. Such amounts are
significantly less than the $21,892,500 of cash payments from the Bacou family
and the spread on stock options foregone by such persons on May 23, 2001
pursuant to discussions with the oversight committee. The amounts are not
directly comparable, however, because they do not take into account the value of
options over Christian Dalloz shares that are expected to be granted to Messrs.
Barr, Bennett and Hebert when the merger is consummated. Additionally, based on
their preliminary understanding, the executives were to relinquish

                                       33
<Page>
their rights to the change of control payments to which they would have
otherwise been entitled pursuant to their employment agreements. See
"--Interests of Certain Persons in the Merger and Related Acquisition
Transactions, Potential Conflicts of Interest."

    In response to the May 9, 2001 letter from Deutsche Bank on behalf of the
Bacou family, in late May 2001 the oversight committee's legal advisors made a
telephone call to the Bacou Group's U.S. legal advisors indicating that the
oversight committee was unwilling to recommend the merger at a price of $27 per
share. The oversight committee's determination on May 15, 2001, that the
proposed $27 per share cash consideration was inadequate was based on the ranges
of values indicated through the auction process, its own general knowledge of
Bacou USA's business, operations and prospects, their review of UBS Warburg
LLC's presentation at the May 8, 2001 meeting and discussions with UBS Warburg
LLC. The closing price for the shares of Bacou USA on the trading day which
preceded the determination by the oversight committee on May 15, 2001 was $24.80
per share. The financial and legal advisors to the Bacou Group engaged in
further discussions with the oversight committee and its financial and legal
advisors between May 17, 2001 and May 22, 2001. During this period the Bacou
family increased the price proposed to be paid to the public stockholders first
to $27.50 and then to $28. Each revised offer was rejected by the oversight
committee. Based on further discussions on the afternoon and evening of May 22,
2001 between the Bacou Group's financial and legal advisors and the oversight
committee and its financial and legal advisors, an understanding was reached
that the oversight committee would be prepared to recommend a transaction that
resulted in merger consideration to the stockholders of Bacou USA other than
Bacou S.A. of $28.50 per share subject to formal oversight committee approval
and the receipt of a favorable fairness opinion from UBS Warburg LLC. In
reaching the conclusion to recommend a price of $28.50 per share, the oversight
committee believed that such price was fair to the public stockholders of Bacou
USA for the reasons set forth under "SPECIAL FACTORS--Bacou USA's Position as to
the Fairness of the Merger". Although the oversight committee, at such time, had
not yet received a fairness opinion from UBS Warburg LLC, UBS Warburg LLC had
informed the oversight committee that, subject to completion of its internal
approvals and procedures, it would be prepared to deliver such an opinion at
that price. Bacou S.A. and the Bacou family agreed to recommend this price to
Christian Dalloz and Christian Dalloz accepted.

    On May 25, 2001, the oversight committee met to consider, together with its
legal advisors and financial advisors by conference call, the terms of the
proposed merger agreement and the merger. Representatives of the oversight
committee's independent financial advisor, UBS Warburg LLC, then discussed with
the oversight committee the financial terms of the merger and described the
analyses that UBS Warburg LLC had performed in connection with its review of the
proposed merger consideration. UBS Warburg LLC reviewed the process implemented
by the Bacou Group to attract the $28.50 per share merger consideration. UBS
Warburg LLC then delivered its oral opinion, which was subsequently confirmed in
writing, that the consideration of $28.50 per share in cash to be received by
the stockholders of Bacou USA, other than Bacou S.A., in the merger is fair from
a financial point of view to such stockholders. See "SPECIAL FACTORS--Opinion of
UBS Warburg LLC." The oversight committee then unanimously determined that the
merger is fair to the stockholders of Bacou USA, other than Bacou S.A. and its
affiliates, and that the execution and delivery of the merger agreement and the
consummation of the transactions contemplated thereby are advisable and in the
best interests of Bacou USA and determined to recommend that the full board of
directors approve and adopt the merger and the merger agreement.

    Between May 26, 2001 and May 29, 2001, the parties engaged in additional
negotiations relating to matters in connection with the financing of the
transaction and the negotiation of other terms of the merger agreement and other
documentation. In particular, they resolved final issues related to due
diligence conditions to the commitments made by Christian Dalloz' financing
sources and resolved technical issues related to the merger agreement. On
May 29, 2001, the Share Option Purchase

                                       34
<Page>
Agreement was amended to allow for a deferred payment of the consideration to be
paid pursuant to such agreement by Sauvegarde LLC to Mevra Beheer.

    On May 29, 2001, our full board of directors convened a meeting to consider,
together with the advice of the Bacou Group's U.S. legal advisor and financial
advisor, the final terms of the merger agreement and the merger. In connection
with its consideration of the merger agreement and the merger, the board of
directors had previously received from the oversight committee and reviewed a
copy of the written materials prepared by UBS Warburg LLC for the oversight
committee at the oversight committee meeting on May 25, 2001 in support of UBS
Warburg LLC's fairness opinion. At this meeting, a representative of White &
Case described to the board of directors its fiduciary duties in connection with
the consideration of the merger agreement and the merger. A representative of
Deutsche Bank then summarized the sale process for the board of directors. The
Deutsche Bank representative emphasized that prior to the Christian Dalloz
proposal no other potential acquirer had made an offer to purchase Bacou USA
which involved consideration to the public stockholders of Bacou USA in excess
of $25 per share. The White & Case representative then described the significant
provisions of the merger agreement. Mr. Verrecchia then reported on the
discussions and recommendation of the oversight committee. He described the
oversight committee's meeting on May 25, 2001 and described in detail the
reasons for the oversight committee's unanimous recommendation that the full
board of directors approve the merger agreement and the merger. After further
discussion, the board of directors unanimously approved resolutions to the
following effect: (1) that the merger agreement is fair to the stockholders of
Bacou USA, other than Bacou S.A.; (2) that the merger agreement and the merger
are advisable and in the best interests of Bacou USA and its stockholders, other
than Bacou S.A.; and (3) authorization and approval of the merger agreement and
the consummation of the transactions contemplated thereby, including the merger.
See "SPECIAL FACTORS--Reasons for the Approvals by the Oversight Committee and
our Board of Directors." Following the meeting, we executed the merger
agreement. On May 30, 2001, Bacou S.A. and Bacou USA issued a press release
announcing the merger and the overall sale of the Bacou Group.

THE MAJORITY STOCKHOLDER; NO FURTHER STOCKHOLDER APPROVAL REQUIRED

    On August 3, 2001 Bacou S.A., as our majority stockholder, who at that time
held approximately 71.4% of our shares eligible to vote on the merger, executed
an irrevocable written consent and proxy to approve and adopt the merger
agreement and the merger. Its vote was sufficient for stockholder approval and
adoption of the merger agreement and the merger under Delaware law, our
Certificate of Incorporation and Bylaws. Therefore, no further vote by our
stockholders is required to approve the merger agreement and the merger and the
transaction is not structured to require the approval of a majority of
unaffiliated stockholders of Bacou USA.

OPINION OF UBS WARBURG LLC

    Under the terms of an engagement letter, dated August 21, 2000, the
oversight committee retained PaineWebber Incorporated, whose investment banking
business was subsequently combined with UBS Warburg LLC, to provide financial
advisory services and a financial fairness opinion to the oversight committee in
connection with the merger. At the meeting of the oversight committee held on
May 25, 2001, UBS Warburg LLC delivered its oral opinion to the effect that, as
of the date of the opinion and based on and subject to the matters set forth in
the opinion, the consideration of $28.50 per share in cash to be received by our
holders, other than Bacou S.A., in the merger is fair from a financial point of
view to such stockholders. The opinion was confirmed by delivery of a written
opinion dated May 25, 2001.

                                       35

    The following summary of the UBS Warburg LLC opinion is qualified in its
entirety by reference to the full text of the opinion. The full text of the
opinion sets forth the assumptions made, procedures followed, matters considered
and limitations on the scope of the review undertaken, by UBS Warburg LLC and is
attached as Appendix B to this information statement and is incorporated in this
information statement by reference. We encourage you to read carefully the UBS
Warburg LLC opinion in its entirety. UBS Warburg has consented to the inclusion
of its opinion in its entirety in this information statement and as an exhibit
to the Schedule 13E-3 filed with the Securities and Exchange Commission in
connection with the merger.

    UBS Warburg LLC's opinion:

    - is addressed to the oversight committee;

    - relates only to the fairness from a financial point of view of the $28.50
      per share cash consideration to be received by our stockholders, other
      than Bacou S.A., in the merger;

    - does not address our underlying business decision to effect the merger;
      and

    - is necessarily based upon economic, monetary, market and other conditions
      as in effect on, and the information made available to UBS Warburg LLC as
      of, the date of the opinion.

    In arriving at its opinion, UBS Warburg LLC, among other things:

    - reviewed certain publicly available business and historical financial
      information relating to us;

    - reviewed the reported prices and trading activity for our common stock;

    - reviewed certain internal financial information and other data relating to
      the business and financial prospects of Bacou USA, including estimates and
      financial forecasts prepared by the management of Bacou USA, which were
      provided to UBS Warburg LLC by us in September 2000 and are not publicly
      available;

    - reviewed certain historical pro forma financial information relating to
      Bacou S.A. prepared by the management of Bacou S.A., which were provided
      to UBS Warburg LLC by Bacou S.A. and are not publicly available;

    - conducted discussions with members of our senior management;

    - reviewed publicly available financial and stock market data with respect
      to certain other companies in lines of business UBS Warburg LLC believed

      financial terms of certain other transactions which UBS Warburg LLC
      believed to be generally relevant;

    - reviewed drafts of the merger agreement and the French master agreement;
      and

    - conducted such other financial studies, analyses and investigations and
      considered such other information as UBS Warburg LLC deemed necessary or
      appropriate.

    In connection with its review, at the oversight committee's direction, UBS
Warburg LLC:

    - assumed that we, Christian Dalloz and Daniel U. S. Sub will comply with
      all material terms of the merger agreement, and that the parties thereto
      will comply with all material terms of the French master agreement;

    - did not assume any responsibility for independent verification of any of
      the information referred to above and relied on it as being complete and
      accurate in all material respects; and

    - did not make any independent evaluation or appraisal of any of the assets
      or liabilities (contingent or otherwise) of Bacou USA, nor was UBS Warburg
      LLC furnished with any such evaluation or appraisal.

    UBS Warburg LLC was not asked to, and did not, participate in the
negotiation or structuring of the merger or recommend the specific consideration
payable in the merger, which was determined

                                       36
<Page>
through negotiations among Christian Dalloz, Bacou S.A., the Bacou family, Bacou
USA and the oversight committee. In addition, UBS Warburg LLC was not asked to,
and did not, at the oversight committee's direction, offer any opinion as to the
material terms of the merger agreement or the French master agreement or the
structure of the transactions contemplated by such agreements. Although UBS
Warburg LLC was not authorized to and did not solicit indications of interest
from any third party with respect to a business combination with Bacou USA, UBS
Warburg LLC understood that Bacou S.A.'s and Bacou USA's financial advisor
solicited indications from third parties with respect to a business combination
with Bacou S.A. and Bacou USA.

    In preparing the financial and comparative analyses in connection with the
rendering of its opinion, UBS Warburg LLC was not provided by us with current
financial forecasts as to our business and financial prospects, as prepared by
our management. Accordingly, at the direction of the oversight committee, in
reaching its opinion, UBS Warburg LLC did not take into consideration any
forecasts of Bacou USA's future business or financial performance prepared by
our management. The oversight committee did not deem the July 2000 financial
forecasts prepared by Bacou USA's management to be relevant and directed UBS
Warburg LLC to disregard them in performing its analyses for a number of reasons
including: (1) Bacou USA generally does not prepare forecasts; (2) forecasts
were prepared in July 2000 and at the time that UBS Warburg LLC was preparing
its fairness opinion the actual operating performance of Bacou USA was such as
to indicate that the forecasts were no longer reasonable; and (3) a downturn in
economic and industry trends. The oversight committee did not deem the analysis
prepared by management in March 2001 to be relevant because it was not developed
from actual Bacou USA operating data and because it was prepared only for the
purpose of assisting Christian Dalloz to arrange its financing and not for the
purpose of establishing value for Bacou USA.

    The preparation of a fairness opinion is a complex analytical process
involving various determinations as to the most appropriate and relevant methods
of financial analysis and the application of those methods to the particular
circumstances and, therefore, is not susceptible to partial analysis or summary
descriptions. In arriving at its opinion, UBS Warburg LLC made qualitative
judgments as to the significance and relevance of each analysis and factor
considered by it, and based on the results of all the analyses undertaken by it
and assessed as a whole. UBS Warburg LLC did not draw conclusions, in isolation,
from or with regard to any one factor or method of analysis. Accordingly, UBS
Warburg LLC believes that its analyses must be considered as a whole and that
selecting portions of its analyses and the factors considered by it, without
considering all analyses and factors, could create an incomplete view of the
processes underlying the analyses set forth in its opinion.

    In performing its analyses, UBS Warburg LLC made numerous assumptions with
respect to industry performance, general business, financial, market and
economic conditions and other matters, many of which are beyond our control. No
company, transaction or business used in those analyses as a comparison is
identical to us or our businesses or the merger, nor is an evaluation of the
results entirely mathematical. Rather, the analyses involve complex
considerations and judgments concerning financial and operating characteristics
and other factors that could affect the operating results, public trading or
other values of the companies or transactions being analyzed.

    The estimates contained in the analyses performed by UBS Warburg LLC and the
ranges of valuations resulting from any particular analysis are not necessarily
indicative of actual values or predictive of future results or values, which may
be significantly more or less favorable than suggested by these analyses. In
addition, analyses relating to the value of securities do not purport to be
appraisals or to reflect the prices at which a business might actually be sold
or the prices at which any securities may trade at the present time or at any
time in the future.

    The following is a summary of the material financial analyses used by UBS
Warburg LLC in connection with the rendering of its opinion. The financial
analyses summarized below include information presented in tabular format. In
order to understand the financial analyses fully, the tables

                                       37

must be read together with the text of each summary. Considering the data set
forth below without considering the full narrative description of the financial
analyses, including the methodologies and assumptions underlying the analyses,
could create a misleading or incomplete view of the financial analyses.

    HISTORICAL STOCK PERFORMANCE.  UBS Warburg LLC reviewed historical trading
prices for our common stock. This stock price performance review indicated that,
for the 52 weeks ended July 7, 2000, the last trading day before Bacou S.A. and
Bacou USA announced that they were exploring strategic alternatives, the low and
high closing prices for the common stock were $14.56 and $21.88, respectively.
This review further indicated that, for the 52 weeks ended May 24, 2001, the low
and high closing prices for the common stock were $18.00 and $28.38,
respectively. UBS Warburg LLC also reviewed the closing prices of the common
stock on July 7, 2000 and May 24, 2001 and average closing prices and the low
and high closing prices over periods prior to July 7, 2000 and May 24, 2001,

    SELECTED COMPARABLE PUBLIC COMPANY ANALYSIS.  UBS Warburg LLC compared
selected financial information, ratios and public market multiples for Bacou USA
to the corresponding data for the following six publicly-traded companies:

    - Brady Corporation

    - Federal Signal Corporation

    - Landauer, Inc.

    - Mine Safety Appliances Company

    - Sola International Inc.

    - UniFirst Corporation

    UBS Warburg LLC chose the selected companies because they were
publicly-traded companies that, for purposes of the analysis, UBS Warburg LLC
considered reasonably similar to Bacou USA in that these companies operate in
the safety product manufacturing industry. The selected public companies may
significantly differ from Bacou USA based on, among other things, the size of
the

                                       38
<Page>
companies, the geographic coverage of the companies' operations and the
particular business segments in which the companies focus.

    UBS Warburg LLC reviewed, among other information, the comparable companies'
multiples of total enterprise value, referred to as TEV, which consists of the
market value of the particular company's equity plus the value of the particular
company's total debt and preferred stock, minus cash, cash equivalents and
marketable securities to:

    - latest twelve months, referred to as LTM, revenue;

    - LTM adjusted earnings before interest, taxes, depreciation and
      amortization, referred to as EBITDA; and

    - LTM adjusted earnings before interest and taxes, referred to as EBIT.

    UBS Warburg LLC also reviewed, among other information, the comparable
companies' price/ earnings multiples, referred to as P/E, for the LTM and
projected P/E multiples, based on median First Call consensus earnings estimates
as of April 30, 2001 for the calendar year ending December 31, 2001.

    The Bacou USA comparable companies analysis resulted in the following ranges
of implied multiples:

Vestar Capital Partners            Cabot Safety Corp.
Federal Signal Corp.               Justrite Manufacturing Company
</Table>

    UBS Warburg LLC chose the selected transactions because they were business
combinations that, for the purposes of the analysis, UBS Warburg LLC considered
to be reasonably similar to the merger in that these transactions involved
companies in the safety product manufacturing industry. The selected
transactions may differ significantly from the merger based on, among other
things, the size of the transactions, the structure of the transactions and the
dates that the transactions were announced and consummated.

    UBS Warburg LLC reviewed, among other things, the TEVs implied in the
relevant transactions as a multiple of LTM revenue, LTM adjusted EBITDA and LTM
adjusted EBIT and the equity market value, referred to as EMV, implied in the
relevant transactions as a multiple of LTM adjusted net

                                       39

income and book value. In certain cases the data was reviewed on a pro forma

transactions and for the merger:

</Table>

    All multiples for the selected transactions were based on publicly available
information at the time of the announcement of the particular transaction. LTM
data for Bacou USA, which was reviewed on a pro forma adjusted basis, was based
on its applicable Forms 10-K and 10-Q and Bacou USA internal financial reports.

    PREMIUMS PAID ANALYSIS.  UBS Warburg LLC reviewed selected purchase price
per share premiums paid in cash acquisitions of, and minority close-out
transactions involving, publicly-traded, domestic companies in non-financial
industries announced, pending or completed, excluding withdrawn transactions and
certain transactions that in UBS Warburg LLC's judgment were non-representative,
from January 1, 1999 through May 24, 2001, with deal sizes between $250 million
and $1.0 billion, except for minority close-out transactions for which no size
limitations were imposed. This analysis indicated mean and median and high and
low premiums to the target's closing stock prices on dates prior to the
announcement as set forth in the following table. The premiums for Bacou USA
were calculated based on Bacou USA's closing stock prices one day, one week and
one month prior to Bacou S.A. and Bacou USA's announcement on July 10, 2000
regarding the exploration of strategic alternatives. This date was chosen
because it represented the last trading day before Bacou S.A. and Bacou USA
announced that they were exploring strategic alternatives.

December 31, 2000 balance sheet data for Bacou S.A. were based on Bacou S.A.

    FEE ARRANGEMENT.  Pursuant to the engagement letter, dated August 21, 2000,
between PaineWebber Incorporated, whose investment banking business was
subsequently combined with UBS Warburg LLC, and the oversight committee,
PaineWebber was paid an initial fee of $100,000 by Bacou USA and, for rendering
its financial fairness opinion, UBS Warburg LLC earned a fee of $800,000 payable
by Bacou USA, independent of the result of the opinion. Bacou USA also agreed to
reimburse UBS Warburg LLC for its expenses incurred in performing its services.
UBS Warburg LLC will not be entitled to any additional fees or compensation with
respect to the merger. In addition, Bacou USA has agreed to indemnify UBS
Warburg LLC and its affiliates, their respective directors, officers, agents and
employees and each person, if any, controlling UBS Warburg LLC or any of its
affiliates against liabilities and expenses related to or arising out of UBS
Warburg LLC's engagement and any related transactions.

    The oversight committee selected UBS Warburg LLC based on its experience,
expertise and reputation. UBS Warburg LLC is an internationally recognized
investment banking firm that regularly engages in the valuation of securities in
connection with mergers and acquisitions, negotiated underwritings, competitive
bids, secondary distributions of listed and unlisted securities, private
placements and valuations for estate, corporate and other purposes. Prior to
this engagement, UBS Warburg LLC had not provided investment banking and other
financial services to Bacou USA. In the ordinary course of business, UBS Warburg
LLC, its successors and affiliates may trade or have traded securities of Bacou
USA and/or Christian Dalloz S.A. for their own accounts and, accordingly, may at
any time hold a long or short position in such securities. As of February 13,
2001, an affiliate of UBS Warburg LLC held a long position of approximately
930,496 shares of Bacou USA common stock, which position had been held by the
UBS Warburg affiliate prior to the closing of the merger of the parent of
PaineWebber Incorporated with another affiliate of UBS Warburg LLC.

    A copy of the written materials provided by UBS Warburg LLC and distributed
to the oversight committee at the May 25, 2001 meeting has been filed as an
exhibit to the Schedule 13E-3 filed with the Securities and Exchange Commission
in connection with the merger and is available for inspection and copying at our
principal executive offices during our regular business hours by any
stockholder. A

OUR ANALYSIS OF FUTURE PERFORMANCE

    In connection with Christian Dalloz' review of Bacou USA and in the course
of the negotiations between the Bacou Group and Christian Dalloz described in
"SPECIAL FACTORS--Background of the Merger and the Related Acquisition
Transactions," Bacou USA provided Christian Dalloz with certain non-public
business and financial information. Initially, Bacou USA provided Christian
Dalloz with projections prepared by Bacou USA's management in July 2000. We have
not provided the July 2000 financial forecasts in this information statement
because we do not believe they are relevant because: (1) we do not generally
prepare forecasts; (2) the July 2000 forecasts were prepared more than ten
months prior to the signing of the merger agreement, by which time the actual
operating performance of Bacou USA was such as to indicate that such forecasts
were no longer reasonable; and (3) there has been a downturn in economic and
industry trends since the forecasts were prepared. Subsequently, Christian
Dalloz was provided with the March 2001 financial analysis set forth below. The
non-public information provided by Bacou USA set forth below was prepared by
Bacou USA's management in March 2001 for the purpose of assisting Christian
Dalloz in its financing effort. Such analysis was designed to reflect a
potential future operating performance of Bacou USA assuming Bacou USA achieved
in 2001 through 2004 the performance levels as generally reflected in financial
analysts' expectations for Bacou USA in 2001. This analysis did not reflect the
actual operating results of Bacou USA at such time. The oversight committee, our
board of directors and UBS Warburg LLC reviewed the Bacou USA July 2000
forecasts but did not consider them, with respect to the oversight committee and
our board of directors, in connection with approving the merger agreement and
the merger, or with respect to UBS Warburg LLC, in its analysis of the fairness
from a financial point of view of the merger consideration to be received by our
public stockholders, because based on the changing nature of the economy at the
time, the forecasts were not deemed by the board of directors or the oversight
committee to be reliable in reflecting the value of Bacou USA. None of the
parties considered the March 2001 financial analysis because it was not
developed from actual Bacou USA operating data and because it was prepared only
for the purpose of assisting Christian Dalloz to arrange its financing and not
for the purpose of establishing value for Bacou USA.

    Bacou USA does not, as a matter of course, publicly disclose forecasts or
analysis as to future revenues or earnings. The Bacou USA analysis was not
prepared with a view to public disclosure and is included in this information
statement only because such information was made available to Christian Dalloz
in connection with arranging financing for its acquisition of Bacou USA.
Accordingly, it is expected that there will be differences between actual
results and the potential results reflected in the analysis, and actual results
may be materially different than those set forth below. The Bacou USA analysis
was not prepared with a view to comply with the published guidelines of the SEC
regarding forecasts, nor was it prepared in accordance with the guidelines
established by the American Institute of Certified Public Accountants for
preparation and presentation of financial forecasts. Moreover, KPMG, Bacou USA's
independent auditors, has not examined, compiled or applied any procedures to
the Bacou USA analysis in accordance with standards established by the American
Institute of Certified Public Accountants and expresses no opinion or any
assurance on its reasonableness, accuracy or achievability. These
forward-looking statements reflect numerous assumptions made by Bacou USA's
management, many of which are inherently uncertain and subject to change. In
addition, factors such as industry performance, general business, economic,
regulatory, and market and financial conditions, all of which are difficult to
predict, may cause the Bacou USA analysis or the underlying assumptions to be
inaccurate. Accordingly, we believe that the Bacou USA analysis may not be
realized, and actual results may be materially less favorable than those
contained in the Bacou USA analysis.

    The inclusion of the Bacou USA analysis herein should not be regarded as an
indication that the oversight committee, our board of directors, Bacou USA,
Christian Dalloz or any of their respective

                                       42
<Page>
financial advisors considered or consider the Bacou USA analysis to be a
reliable prediction of future events, and the Bacou USA analysis should not be
relied upon as such. To the extent the Bacou USA analysis represents Bacou USA
management's analysis of possible future performance, such estimate is made only
as of the date of such analysis and is not made as of any later date, and
stockholders should take this into account when evaluating any factors or
analyses based on the Bacou USA analysis.

Christian Dalloz is summarized below:

PRESENTATION BY DEUTSCHE BANK ON MAY 29, 2001

    At the May 29, 2001 meeting of Bacou USA's full board of directors to
consider the final terms of the merger agreement and the merger, Deutsche Bank
summarized the proposed transaction, described the Christian Dalloz offer for
the shareholders of Bacou SA, Engineering Henri Bacou and the public
stockholders of Bacou USA, and reviewed the sale process.

    Deutsche Bank has not acted as financial advisor to the Oversight Committee.
Deutsche Bank was not requested to, and did not, render an opinion with respect
to the fairness of the transaction or the consideration to be paid in the
merger, or as to valuation or otherwise. The materials prepared by Deutsche Bank
in connection with the merger, including but not limited to the May 29, 2001
information materials, are not an opinion as to the fairness to Bacou USA or its
shareholders of the transaction or the consideration to be paid in the offer and
merger, do not constitute a recommendation to Bacou USA or its shareholders as
to the transaction or as to any action they should take or not take with respect
to the transaction, and should not be relied on as a basis for any investment
decision.

    Copies of the May 29, 2001 information materials are available for
inspection and copying at Bacou USA's principal executive offices at 10 Thurber
Boulevard, Smithfield, Rhode Island 02917, during regular business hours by any
interested shareholder of Bacou USA or the shareholder's representative who has
been so designated in writing. We have also filed these materials with the
Securities and Exchange Commission as an exhibit to the Schedule 13E-3.

    In connection with Deutsche Bank's role as financial advisor to the Bacou
family and Bacou USA, Deutsche Bank, among other things:

    - reviewed certain publicly available financial information and other
      information concerning Bacou USA;

    - reviewed certain internal analyses and other information furnished to
      Deutsche Bank by the Bacou Group and Bacou USA;

    - held discussions with members of the senior management of the Bacou Group
      and Bacou USA regarding the businesses and prospects of Bacou USA;

                                       43
<Page>
    - reviewed the reported prices and trading activity for the shares;

    - reviewed the financial terms of the proposed transaction between the Bacou
      Group and Christian Dalloz; and

    - performed such other studies and analyses and considered such other
      factors as Deutsche Bank deemed appropriate.

    Deutsche Bank did not assume responsibility for the independent verification
of, and did not independently verify, any information concerning the Bacou
Group, Bacou USA or Christian Dalloz, whether publicly available or furnished to
Deutsche Bank, including, without limitation, any financial information,
forecasts or projections, considered in connection with the preparation and
presentation of the information materials. Accordingly, Deutsche Bank assumed
and relied upon the accuracy and completeness of all such information. Deutsche
Bank, in its role as financial advisor to the Bacou family and Bacou USA, did
not conduct a physical inspection of any of the properties or assets, and did
not prepare or obtain any independent evaluation or appraisal of any of the
assets or liabilities of Bacou USA. The May 29, 2001 information materials
prepared and presented by Deutsche Bank were necessarily based upon economic,
market and other conditions as in effect on, and the information made available
to Deutsche Bank as of, May 29, 2001.

    The following is a summary of the Deutsche Bank May 29, 2001 information
materials and does not purport to be a complete description of the analyses
performed by Deutsche Bank. The following quantitative information, to the
extent it is based on market data, is based on market data as it existed at or
about May 29, 2001, and is not necessarily indicative of current market
conditions. You should understand that the order of analyses and the results
derived from these analyses described below do not represent relative importance
or weight given to these analyses by Deutsche Bank. The summary of the May 29,
2001 information materials described below is qualified in its entirety to the
full text of the materials.

    SUMMARY OF THE TRANSACTION AND KEY TERMS AND CONDITIONS.  The May 29, 2001
presentation described the proposed transaction in summary form including the
transfer of ownership of Bacou SA and Engineering Henri Bacou to Christian
Dalloz, the consideration to be paid to the shareholders of Bacou SA and
Engineering Henri Bacou as well as the public shareholders of Bacou USA, key
shareholder and other agreements, key conditions, transaction timing and
termination date.

    SUMMARY OF THE TRANSACTION STRUCTURE AND ANTICIPATED FINANCING
ARRANGEMENTS.  The May 29, 2001 presentation summarized the ownership structure
of the Bacou Group and Christian Dalloz prior to the proposed transaction, as
well as the ownership structure of the combined entity, Bacou-Dalloz, if a
transaction were to be consummated under the terms of the agreements. Deutsche
Bank also presented a summary of the estimated sources and uses of funds for the
transaction.

    OVERVIEW OF THE SALE PROCESS.  The May 29, 2001 presentation summarized the
key events in the sale process conducted by Deutsche Bank following its
engagement as financial advisor to Bacou USA and the Bacou family, and
summarized in tabular format the numbers of potential buyers contacted (130),
those provided with an information memorandum (87), those which submitted
indications of interest (28) and those participating in management presentations
and detailed diligence reviews (10 including Christian Dalloz).

    OVERVIEW OF CHRISTIAN DALLOZ.  The May 29, 2001 presentation provided a
summary overview of Christian Dalloz based on publicly available information
including key events in the recent history of Christian Dalloz, a short
description of the current business, breakdown of sales by product and
geography, ownership structure, recent stock price performance and key
historical financial data. Deutsche Bank also prepared financial data for 2000
for each of the Bacou Group and Christian Dalloz and calculated the pro forma
contribution of each company to the pro forma combined result on the basis of
revenue, gross profit, net income, total assets, debt and equity.

    HISTORICAL PRICE AND VOLUME PERFORMANCE OF BACOU USA.  The presentation
included a chart of the historical price and volume performance of Bacou USA's
common stock for the period beginning with Bacou USA's initial public offering
through May 22, 2001. The chart highlighted the timing of certain publicly
disclosed events in Bacou USA's history during such period.

    The foregoing summary describes analyses and factors that Deutsche Bank
presented at the May 29, 2001 meeting of the Board of Directors, but it is not a
comprehensive description of all analyses performed and factors considered by
Deutsche Bank in connection with the presentation and its role as financial
advisor to the Bacou family and Bacou USA.

    The terms of the transaction were determined through negotiations between
the Bacou family, the oversight committee and Christian Dalloz and their
respective representatives. Although Deutsche Bank provided advice to Bacou USA
and the Bacou family during the course of these negotiations, the decision to
enter into the transaction was solely that of the Bacou family and Bacou USA.
Deutsche Bank's advice was only one of a number of factors taken into
consideration by the Bacou family and Bacou USA in making their determination to
approve the transaction.

    Deutsche Banc Alex. Brown is an internationally recognized investment
banking firm experienced in providing advice in connection with mergers and
acquisitions and related transactions. BT Alex. Brown, the predecessor to
Deutsche Banc Alex. Brown was named as the lead underwriter in a registration
statement filed by Bacou USA in August 1998 for a proposed public issuance of
common stock. A transaction was not consummated pursuant to this registration
statement. In addition, from time to time, Deutsche Banc Alex. Brown has met
with the senior management of Bacou USA and discussed various strategic and
financial opportunities. Deutsche Banc Alex. Brown and its affiliates may
actively trade securities of Bacou USA for their own account or the account of
their customers and, accordingly, may from time to time hold a long or short
position in such securities.

    Bacou USA selected Deutsche Banc Alex. Brown as financial advisor based on
Deutsche Banc Alex. Brown's qualifications, expertise, reputation and experience
in mergers and acquisitions, historical relationship with Bacou USA, and
knowledge of Bacou USA's operations and assets. Bacou USA has retained Deutsche
Banc Alex. Brown pursuant to an engagement letter agreement dated July 13, 2000.
As compensation for its services in connection with the merger, Bacou USA will
pay Deutsche Banc Alex. Brown a cash fee, a significant portion of which is
dependent upon consummation of a transaction. Regardless of whether the merger
is consummated, Bacou USA has agreed to reimburse Deutsche Banc Alex. Brown for
reasonable fees and disbursements of Deutsche Banc Alex. Brown's counsel and all
of Deutsche Banc Alex. Brown's reasonable travel and other out-of-pocket
expenses incurred in connection with the merger or otherwise arising out of
retention of Deutsche Banc Alex. Brown under the engagement letter. Bacou USA
has also agreed to indemnify Deutsche Banc Alex. Brown and certain related
persons to the full lawful extent against certain liabilities, including certain
liabilities under the federal securities laws arising out of its engagement or
the merger.

REASONS FOR THE APPROVALS BY THE OVERSIGHT COMMITTEE AND OUR BOARD OF DIRECTORS

OVERSIGHT COMMITTEE

    In evaluating the merger, the oversight committee, consisting of two members
of our board of directors, Mr. Alfred J. Verrecchia and Mr. Karl F. Ericson,
each of whom is unaffiliated with the Bacou Group and Christian Dalloz, relied
upon its knowledge of the business, financial condition and prospects of Bacou
USA as well as the advice of its financial and legal advisors. The oversight
committee did not consider the value of Bacou S.A.'s European operations because
the oversight committee did not view the value of Bacou S.A.'s European
operations as being relevant to a valuation of Bacou USA. The members of the
oversight committee have certain interests in the merger which are different
from the interests of the public stockholders of Bacou USA and could be viewed
as creating a potential conflict of interest. See "SPECIAL FACTORS--Interests of
Certain Parties in the Merger and Related Acquisition Transactions; Potential
Conflicts of Interest--Options to Purchase Common

                                       45
<Page>
Stock of Bacou USA" for a more detailed description of those interests. In
determining that the oversight committee would approve and recommend the merger
agreement and the transactions contemplated thereby, including the merger, to
our full board of directors, the oversight committee considered a number of
factors, including the following, each of which factors weighed in favor of the
merger:

        (1) MARKET PRICE AND PREMIUM. The historical market prices and recent
    trading activity of our common stock with a particular emphasis on the
    relationship between the $28.50 per share merger consideration and the
    trading history of our common stock. In particular, the oversight committee
    noted that the $28.50 per share merger consideration:

       - represents a premium of approximately 46% over the $19.50 per share
         closing price of our common stock on the New York Stock Exchange on
         July 7, 2000, the last full trading day before we announced that we
         would explore strategic alternatives to enhance stockholder value with
         Bacou S.A.,

       - represents a premium of approximately 20% over the $23.80 per share
         closing price of our common stock on the New York Stock Exchange on
         May 24, 2001, the last full trading day before the May 25, 2001 meeting
         of the oversight committee at which it approved the execution of the
         merger agreement, and

       - is higher than the 52-week high closing price and the all-time high
         closing price of our common stock on the New York Stock Exchange
         ($28.38 per share) for the period ended May 24, 2001.

        For purposes of the premium analysis, the oversight committee evaluated
    the trading activity of our common stock in the period immediately
    subsequent to the July 10, 2000 announcement that Bacou USA and Bacou S.A.
    would consider strategic alternatives and determined that our closing stock
    price on July 7, 2000 represented the last trading day unaffected by the
    market's reaction to the announcement and related potential for a
    transaction.

        (2) AUCTION PROCESS AND OVERSIGHT COMMITTEE PARTICIPATION. The scope of
    efforts undertaken to effect a transaction involving Bacou USA. The
    oversight committee considered the fact that 130 potential acquirers had
    been contacted regarding their possible interest in acquiring all or part of
    the Bacou Group, 87 potential acquirers had reviewed a confidential
    information memorandum regarding the Bacou Group, and ten potential
    acquirers conducted detailed business and legal due diligence. The oversight
    committee considered the fact that the $28.50 per share merger consideration
    is higher than any price offered by any potential acquirer submitting an
    offer for the Bacou Group during the auction process.

        (3) UBS WARBURG FAIRNESS OPINION. The financial presentation of UBS
    Warburg and UBS Warburg's opinion that, as of the date of such opinion and
    based upon and subject to the matters set forth in the opinion, the
    consideration of $28.50 per share in cash consideration to be received by
    our stockholders, other than Bacou S.A., was fair, from a financial point of
    view, to such stockholders, other than Bacou S.A.

        (4) TRANSACTION STRUCTURE AND FORM OF CONSIDERATION. The fact that the
    price per share to be received in the merger is payable shortly following
    the closing of the merger in cash, thereby eliminating any uncertainties in
    valuing the consideration to be received by our stockholders, other than
    Bacou S.A., and any uncertainties about receipt of the consideration in the
    future. The oversight committee also discussed the consideration to be
    received by shareholders of Bacou S.A. and Engineering Henri Bacou in
    connection with the acquisition of Bacou S.A. and Engineering Henri Bacou.
    In connection with that, the oversight committee discussed the letter
    agreement dated July 14, 2000 between Bacou USA and the Bacou family which
    required that the Bacou family would not accept any offer to purchase their
    interest in Engineering Henri Bacou and Bacou S.A. unless such offer also
    contained an undertaking to offer to purchase the shares of our

                                       46
<Page>
    common stock not owned by Bacou S.A. on substantially similar terms. The
    oversight committee understood that the Bacou family and Bacou USA would
    mutually terminate the letter agreement in order to facilitate the terms of
    the merger and that the letter agreement would not apply to the merger. In
    light of this fact and the fact that the oversight committee determined to
    recommend the merger to our board of directors as being fair to the
    stockholders of Bacou USA other than Bacou S.A. and its affiliates, the
    oversight committee approved the termination of the letter agreement and did
    not consider the letter agreement to be applicable to the merger.

        (5) SIZE AND SCALE. The fact that the safety markets in which we operate
    continue to experience a period of consolidation involving competitors,
    customers and suppliers, making size and scale increasingly important to a
    company's success. The oversight committee considered that the acquisition
    opportunities currently available to us, even if successfully consummated on
    acceptable terms and conditions, may not provide it with sufficient size and
    scale to compete at an appropriate level in the increasingly competitive
    industries in which we operate. The oversight committee also noted our
    relative lack of sufficient size and scale may impact our ability to
    effectively compete with our industry competitors, thereby adversely
    affecting our future value.

        (6) RISKS OF STRATEGIC PLAN. The fact that our long-term strategic plan
    of growth through strategic acquisitions, through expansion of existing
    markets and entering into new markets both domestically and abroad and
    through new product development is subject to numerous risks and
    uncertainties. The oversight committee noted that these risks and
    uncertainties include:

       - the uncertainty that we can identify and consummate attractive
         strategic acquisitions of sufficient size and scale, including the
         related risks of financing, integration and diversion of management's
         attention associated with any such acquisitions,

       - the uncertainty that we can successfully expand existing markets
         (particularly since Bacou USA has a relatively large market share in
         certain of its product lines in the United States) and enter into new
         markets, both domestically and abroad, and if we are successful in
         doing so, the related inherent risks and uncertainties of doing
         business outside the United States,

       - the risk that new product development may not lead to commercially
         successful products, notwithstanding marketing and research and
         development investments which are significant for a company of our
         size, and

       - other risks and uncertainties that might adversely affect our prospects
         on a stand-alone basis include the risk that we will be adversely
         affected by a general economic slowdown in relevant markets in late
         2001 and in 2002.

        (7) POSSIBLE DECLINE IN MARKET PRICE OF COMMON STOCK. The possibility
    that if a merger transaction were not negotiated and we remained as a
    publicly owned corporation, it is possible that because of a decline in the
    market price of the shares of our common stock or the stock market in
    general, the price that might be received by the holders of our shares in
    the open market or in a future transaction might be less than the $28.50
    merger consideration per share price to be received by stockholders in
    connection with the merger.

        (8) AVAILABILITY OF DISSENTERS' RIGHTS. The fact that dissenters' rights
    of appraisal will be available to the holders of our common stock under
    Delaware law in connection with the merger.

        (9) REVIEW OF TRANSACTION WITH MANAGEMENT AND ADVISORS. The oversight
    committee reviewed and discussed with our senior management and legal and
    financial advisors the business, financial, legal and accounting aspects of
    the merger and the terms of, and conditions to, the merger.

                                       47

BOARD OF DIRECTORS OF BACOU USA

    In evaluating the merger, our board of directors relied on its knowledge of
our business, financial condition and prospects. Our board of directors also
considered and relied on the advice of our legal and financial advisors and the
conclusions and unanimous recommendation of the oversight committee described
above. In determining that the board of directors would approve the merger
agreement and the merger, our full board of directors considered the following
additional factors, each of which weighed in favor of the merger:

        (1) The fact that the oversight committee, following a thorough
    consideration of the factors listed in the preceding section, unanimously
    recommended to our board of directors to approve the merger agreement and
    the merger.

        (2) The low likelihood that a third party would be willing to offer a
    higher price than Christian Dalloz in light of (i) Bacou S.A. being our
    majority stockholder with approximately 71.4% of our voting common equity
    interest, (ii) the fact that the Bacou Group held a full auction process and
    following such auction each of the bids that was offered for shares of our
    public stockholders was lower than the $28.50 merger consideration being
    offered by Christian Dalloz and no bid was higher than $25.00 per share and
    (iii) Bacou S.A. having agreed with Christian Dalloz to support the merger.
    Our board of directors considered these to be factors which would
    significantly impede the likelihood of a superior offer and, as such,
    considered it to be a factor weighing in favor of the merger.

        (3) Our board of directors considered the immediate return of value to
    our stockholders through the merger in light of the risks inherent in
    continuing to operate our business in accordance with our long term
    strategy. These risks include factors which are beyond our control,
    particularly the size of the U.S. market, low expectations for organic
    growth of the U.S. market for our products, customer demand for our
    products, the impact of competitive products and pricing, changing market
    conditions and capital constraints on our acquisition strategy. With respect
    to our acquisition strategy, our board of directors considered the
    difficulties of continuing to pursue a growth through acquisition strategy
    in light of the need for additional equity or debt capital to support that
    strategy. Our board of directors believed that the cost of equity capital
    for such purpose would be too high because the recent trading prices of our
    common stock reflected multiples to earnings and revenues that were less
    than the multiples that the board believed we would have to pay to expand
    our business through acquisitions. Additionally, because of the existing
    capital structure of the Bacou Group, including our existing debt levels,
    our board of directors believed that we had limited access to additional
    debt financing to pursue our strategy.

        (4) Our board of directors considered, without expressly adopting, the
    analysis made by UBS Warburg LLC contained in the copy of their presentation
    materials to the oversight committee made available by the oversight
    committee to the full board of directors at the May 29, 2001 meeting. Our
    board examined the market values and trading multiples of comparable
    publicly traded companies included in the comparable company analysis
    prepared by UBS Warburg, including the enterprise value of each of these
    companies as a multiple of their respective LTM revenue, LTM EBITDA and LTM
    EBIT (enterprise value, LTM Revenue, LTM EBITDA and LTM EBIT as defined in
    the earlier section "Opinion of UBS Warburg LLC"). The board also examined
    similar multiples for Bacou USA as implied by the merger consideration of
    $28.50 per share. The board observed that such implied multiples for Bacou
    USA were generally within the range of multiples for the selected companies,
    and weighed in favor of the merger. Our board also considered the comparable
    transaction analysis prepared by UBS Warburg LLC of selected acquisitions
    involving selected companies in the personal protection/safety product
    industries. Our board examined the transaction enterprise values and implied
    valuation multiples of the target companies relative to their respective
    earnings, including the enterprise value of each of these transactions as a
    multiple of the respective target's LTM revenue, LTM EBITDA and LTM EBIT.

    Our board also examined similar multiples for Bacou USA as implied by the
    merger consideration of $28.50 per share. The board observed that the
    implied multiples for Bacou USA were generally within the range of multiples
    for the selected transactions, and weighed in favor of the merger. Our board
    observed that none of the companies or transactions used in the comparable
    company or comparable transaction analysis was comparable in all respects to
    Bacou USA or the merger--the selected companies may significantly differ
    from Bacou USA based on, among other things, the size of the companies, the
    geographic coverage of the companies' operations, their ownership
    structures, the particular business segments in which the companies focus,
    and in the case of comparable transactions, potential synergies to an
    acquirer. They also observed that any of these differences could affect the
    public trading values as well as the transaction values of the companies to
    which Bacou USA and the merger are being compared. Our board of directors
    did not, however, perform its own analysis in this regard. Although our
    board of directors considered these analyses, our board of directors after
    considering the conclusions and recommendation of the oversight committee,
    made the determination to accept the proposed merger consideration.
    Representatives of UBS Warburg LLC were not present and did not otherwise
    participate in the May 29, 2001 meeting. Our board of directors did not seek
    to receive its own fairness opinion because it relied on the fact that the
    oversight committee had received a fairness opinion prepared by UBS Warburg
    and that the oversight committee unanimously recommended the merger.

        (5) Our board of directors considered the terms and conditions of the
    merger agreement, including the amount and form of the merger consideration,
    the parties' mutual representations, warranties and covenants, and the
    conditions to their respective obligations, and the absence of future
    obligations of the public stockholders. Our board of directors considered
    that, although the merger agreement does not include any financing
    condition, the merger agreement is conditioned on the completion of the
    related acquisitions of Engineering Henri Bacou and Bacou S.A. Although
    these acquisitions do contain a financing condition, our board of directors
    was advised by Bacou S.A. and its financial advisors that Christian Dalloz
    had received commitment letters for such financing in customary form which
    mitigated the financing risk. Based on the foregoing, our board of directors
    did not view as unreasonable the risk that the financing condition would not
    be satisfied.

        (6) Our board of directors considered the fact that in recent years the
    historical trading prices of our common stock had traded at multiples to
    earnings that our board of directors did not consider to be indicative of
    the true value of the shares. Our board of directors believed that this, at
    least in part, reflected the fact that we have a small market capitalization
    with limited liquidity for our publicly traded shares and that the stock
    markets have not favored these types of stocks in recent years. Our board of
    directors believed that these trends represented significant impediments,
    that were beyond our control, to attaining greater value for Bacou USA as a
    going concern than the value reflected in the merger consideration.

    The oversight committee and the full board of directors recognize that,
although the completion of the merger will give our stockholders, other than
Bacou S.A., the opportunity to realize a substantial premium over the price at
which our common stock traded before the public announcement of the merger,
completion of the merger will also eliminate the opportunity for our
stockholders, other than Bacou S.A., to participate in any future increases in
our value. The oversight committee and the board of directors also recognized
that certain members of our senior management and board of directors were
required to accept shares of Christian Dalloz as partial consideration for their
Bacou S.A. shares. The oversight committee and our board of directors recognized
that these board members and officers, therefore, may indirectly benefit from
any increases in our value, but will also indirectly bear the risk that our
value will decrease following the merger by virtue of their continuing equity
interests in the combined Bacou-Dalloz group following the merger. Although the
oversight committee and the board of directors realized that these factors do
not weigh in favor of the merger, the oversight committee and the board of
directors believe that:

                                       49
<Page>
    - these factors are mitigated by the fact that our stockholders also will
      not share in the risk that our value decreases following the merger,

    - these factors are outweighed by the other factors weighing in favor of the
      merger described above, and

    - this lost opportunity is reflected in the merger consideration price of
      $28.50 per share.

    The oversight committee and our board of directors recognized that certain
members of our board of directors and senior management have interests in the
merger that are described under "SPECIAL FACTORS--Interests of Certain Parties
in the Merger and Related Acquisition Transactions; Potential Conflicts of
Interest" and that these interests presented potential conflicts of interest.
Although the oversight committee and our board of directors did not consider
this to be a factor in favor of or against the merger, it was a significant
factor in the manner in which the oversight committee and our board of directors
conducted themselves, specifically by delegating broad powers to the oversight
committee, with respect to ensuring that the oversight committee would engage in
vigorous negotiations on behalf of our public stockholders.

    The oversight committee and our board of directors considered requiring that
the merger be approved by a majority of the unaffiliated stockholders of Bacou
USA. However, in light of the fact that the approval of the oversight committee,
acting solely on behalf of the unaffiliated stockholders, was required and
received prior to executing the merger agreement and that the oversight
committee retained its own independent financial adviser to render financial
advice and, if appropriate, issue a fairness opinion with respect to the
consideration to be paid to the unaffiliated stockholders of Bacou USA and that
the oversight committee retained its own legal advisors, our board of directors
and the oversight committee determined that these procedures provided adequate
protection to the unaffiliated stockholders of Bacou USA under applicable law.
Therefore, the approval of a majority of the unaffiliated stockholders was not
sought.

    In light of the number and variety of factors that the oversight committee
and our board of directors considered in connection with their evaluation of the
merger, neither the oversight committee nor our board of directors found it
practicable to quantify or otherwise assign relative weights to the foregoing
factors, and, accordingly, neither the oversight committee nor our board of
directors did so. In addition, individual members of the oversight committee and
our board of directors may have given different weights to different factors.
Rather, the oversight committee and our board of directors viewed their
respective positions and recommendations as being based on the totality of the
information presented to and considered by each of them.

    Under our Certificate of Incorporation, a plan of merger requires the
affirmative vote of at least a majority of all outstanding shares entitled to
vote thereon to be adopted. Our board of directors and the oversight committee
recognize that the approval of the holders of the outstanding shares held by
stockholders other than Bacou S.A. is not required to consummate the merger.

    OUR BOARD OF DIRECTORS, AFTER CONSIDERING THE UNANIMOUS RECOMMENDATION OF
THE OVERSIGHT COMMITTEE, UNANIMOUSLY DETERMINED THAT THE MERGER IS FAIR TO OUR
STOCKHOLDERS, OTHER THAN BACOU S.A., AND THE MERGER AGREEMENT AND THE MERGER ARE
ADVISABLE AND IN OUR BEST INTERESTS AND THE BEST INTERESTS OF OUR STOCKHOLDERS,
OTHER THAN BACOU S.A.

BACOU USA'S POSITION AS TO THE FAIRNESS OF THE MERGER

    We believe the merger to be fair to our stockholders who are unaffiliated
with Bacou S.A. and its affiliates, based upon numerous factors, including the
following material factors:

    - the fact that the merger consideration of $28.50 per share of common stock
      (1) represents a premium of approximately 46% over the $19.50 per share
      closing price of our common stock on the New York Stock Exchange on
      July 7, 2000, the last full trading day before we announced

                                       50
<Page>
      that we would explore strategic alternatives to enhance stockholder value
      with Bacou S.A., and a premium of approximately 20% over the $23.80 per
      share closing price of our common stock on the New York Stock Exchange on
      May 24, 2001, the last full trading day before the May 25, 2001 meeting of
      the oversight committee at which it approved the execution of the merger
      agreement, and (2) is higher than the 52-week and the all-time high
      closing price of our common stock on the New York Stock Exchange ($28.38
      per share) for the period ended May 24, 2001;

    - the unanimous approval of the merger by the oversight committee and the
      fact that the members of the oversight committee, based on the factors
      described in "SPECIAL FACTORS--Reasons for the Approvals of the Oversight
      Committee and our Board of Directors," determined that the merger is fair
      to us and our stockholders, other than Bacou S.A. and its affiliates, and
      declared that the merger agreement is advisable;

    - the fact that the merger consideration to our public stockholders and the
      merger agreement was extensively negotiated between the legal
      representatives of the oversight committee, representatives of Bacou USA,
      representatives of Bacou S.A. and representatives of Christian Dalloz;

    - the fact that the oversight committee engaged UBS Warburg LLC, a leading
      internationally recognized investment bank, and that UBS Warburg LLC
      rendered an opinion to the oversight committee as to the fairness of the
      merger consideration from a financial point of view to our stockholders,
      other than Bacou S.A.; and

    - the factors considered by the oversight committee and our board of
      directors, and the analysis of the oversight committee and our board of
      directors referred to under "SPECIAL FACTORS--Reasons for the Approval of
      the Oversight Committee and our Board of Directors."

    Our board of directors viewed the $19.50 per share closing price on that
last full trading day before the announcement of Bacou USA's exploration of
strategic alternatives to be relevant because the announcement triggered a
significant increase in the trading price of Bacou USA's stock.

    The oversight committee and the board of directors also understood that our
obligation to consummate the merger is not conditioned on the favorable vote of
a majority of disinterested stockholders. The oversight committee and the board
of directors determined that the merger, nevertheless, was procedurally fair
because, among other things:

    - the members of the oversight committee who participated in the
      negotiations regarding the merger on behalf of our stockholders are not
      affiliated with Christian Dalloz, the Bacou family or Bacou S.A. and are
      not employees of Bacou USA or Bacou S.A.;

    - the oversight committee retained UBS Warburg LLC, who is not affiliated
      with Christian Dalloz, the Bacou family or Bacou USA's or Bacou S.A.'s
      management, to serve as independent financial advisor to the oversight
      committee and to render a financial fairness opinion with respect to the
      merger;

    - the oversight committee engaged Edwards & Angell LLP to serve as legal
      advisor to the oversight committee;

    - Bacou S.A. retained Deutsche Bank Alex.Brown to conduct an auction for the
      sale of the Bacou Group, including Bacou USA, during which 130 potential
      acquirers were contacted regarding their possible interest in acquiring
      all or part of the Bacou Group, 87 potential bidders reviewed a
      confidential information memorandum regarding the Bacou Group, ten
      potential acquirers conducted detailed business and legal due diligence
      reviews and the Christian Dalloz offer for our stockholders, other than
      Bacou S.A. and its affiliates, was the highest and best offer received
      from any party;

                                       51
<Page>
    - the $28.50 merger consideration and the other terms and conditions of the
      merger agreement resulted from active bargaining among Bacou USA, Bacou
      S.A., Christian Dalloz and the oversight committee; and

    - the merger agreement and the merger were unanimously approved by the
      oversight committee.

    In considering the fairness of the merger to our stockholders who are
unaffiliated with Bacou S.A. and its affiliates, the oversight committee and the
board of directors did not consider our net book value or liquidation value. The
oversight committee and the board of directors believed that these values would
be lower than and would not be indicative of our value as a going concern. Our
net book value per share as of March 31, 2001 was $12.23. This value is
substantially below the $28.50 per share cash merger consideration. The
oversight committee and the board of directors further believe, based on their
knowledge of Bacou USA and its asset values, that our liquidation value, which
takes into account the appreciated value of our assets, also would be
substantially below the merger consideration. The oversight committee and the
board of directors recognized, however, that neither we nor UBS Warburg LLC has
undertaken a liquidation analysis because the oversight committee and the board
of directors believe that the liquidation value of our assets would not be
indicative of our value.

    Neither the oversight committee nor the board of directors conducted a going
concern analysis of Bacou USA. In this regard, however, the oversight committee
and the board of directors considered the results of the extensive auction
process as indicative of the price that the market was willing to pay for Bacou
USA as a going concern. The bidding instructions in the auction made it clear
that only bids for the entire Bacou Group would be considered and there was no
attempt to sell the assets of the Bacou Group or Bacou USA other than in their
entirety. The indications of interest and offers resulting from the auction
process provided separate valuations for Bacou USA. The board of directors and
the oversight committee believed, based on the indications of interest and
offers received in the auction process, that each potential acquirer in the
auction intended to purchase the entire Bacou Group and Bacou USA as a going
concern and to continue to operate Bacou USA as a going concern if it was
successful in acquiring the Bacou Group. Therefore, the board of directors and
the oversight committee concluded that the auction process was indicative of
what a potential purchaser would be willing to pay for Bacou USA as a going
concern and that a separate "going concern" analysis of Bacou USA was not
necessary.

    After considering the foregoing, we believe the merger consideration to be
fair to our stockholders, other than Bacou S.A. and its affiliates. In reaching
this determination we have not assigned specific weights to particular factors,
and considered all factors as a whole. None of the factors that we considered
led us to believe that the merger was unfair to our stockholders, other than
Bacou S.A. and its affiliates.

    None of the members of our board of directors, in their respective capacity
as such, received any reports, opinions or appraisals from any outside party
relating to the merger or the fairness of the consideration to be received by
the stockholders, other than those received by the oversight committee from UBS
Warburg LLC. See "SPECIAL FACTORS--Opinion of UBS Warburg LLC."

BACOU S.A.'S, ENGINEERING HENRI BACOU'S AND THE BACOU FAMILY'S POSITIONS AS TO
  THE FAIRNESS OF THE MERGER

    Each of Bacou S.A., Engineering Henri Bacou and the Bacou family (Philippe
Bacou, Christophe Bacou, Jacqueline Maggi Bacou and Veronique Mirabel) believes
that the merger is fair to our stockholders who are unaffiliated with Bacou S.A.
and its affiliates, based on the same conclusions, and the bases therefor,
reached by the Bacou USA board of directors in approving the merger, as set
forth above, and expressly adopts those conclusions of the board of directors as
to the fairness and the reasons for the merger.

    Although UBS Warburg LLC was engaged by the oversight committee, and not by
our board of directors, Bacou USA, Bacou S.A., Engineering Henri Bacou or the
Bacou family, the fact that a

                                       52
<Page>
qualified financial advisor rendered an opinion to the oversight committee as to
the fairness of the merger consideration, from a financial point of view to our
stockholders who are unaffiliated with Bacou S.A. and its affiliates,
nevertheless was a relevant factor in the determination by Bacou S.A.,
Engineering Henri Bacou and the Bacou family that the merger is fair to our
stockholders who are unaffiliated with Bacou S.A. and its affiliates.

    Bacou S.A., Engineering Henri Bacou and the Bacou family did not receive any
reports, opinions or appraisals from any outside party relating to the merger or
the fairness of the consideration to be received by our stockholders, other than
Bacou S.A. and its affiliates.

MESSRS. STEPAN'S, BARR'S, HEBERT'S AND BENNETT'S POSITION AS TO THE FAIRNESS OF
  THE MERGER

    Each of Messrs. Stepan, Barr, Hebert and Bennett believes that the merger is
fair to the stockholders of Bacou USA who are unaffiliated with Bacou S.A. and
its affiliates, based on the same conclusions, and the bases therefor, reached
by the Bacou USA board of directors in approving the merger, as set forth above,
and expressly adopt those conclusions of the board of directors as to the
fairness and the reasons for the merger.

    Although UBS Warburg was engaged by the oversight committee and not by our
board of directors, the fact that a qualified independent financial adviser
rendered an opinion to the oversight committee as to the fairness of the merger
consideration, from a financial point of view to the public stockholders of
Bacou USA, was a relevant factor in the determination by Messrs. Stepan, Barr,
Hebert and Bennett that the merger is fair to the unaffiliated stockholders of
Bacou USA.

    Messrs. Stepan, Barr, Hebert and Bennett did not receive any reports,
opinions or appraisals from any outside party relating to the merger or the
fairness of the consideration to be received by the unaffiliated stockholders of
Bacou USA.

    Messrs. Stepan, Barr, Hebert and Bennett have a potential conflict of
interest with respect to the merger agreement and the merger, in that they will
receive certain payments and other benefits in connection with the consummation
of the merger and the related acquisition transactions as described in detail in
"SPECIAL FACTORS--Interests of Certain Parties in the Merger and Related
Acquisition Transactions; Potential Conflicts of Interest."

CHRISTIAN DALLOZ' AND DANIEL U. S. SUB'S POSITION AS TO THE FAIRNESS OF THE
  MERGER

    Christian Dalloz and Daniel U. S. Sub expressly adopt the conclusions of the
Bacou USA board of directors described in "Reasons for the Approvals of the
Oversight Committee and our Board of Directors--Board of Directors of Bacou
USA." Christian Dalloz and Daniel U. S. Sub believe that the merger is fair to
the Bacou USA stockholders who are unaffiliated with Bacou S.A., based on the
same conclusions, and the bases therefor, reached by the Bacou USA board of
directors in approving the merger, as set forth above, and based on the fact
that the merger was approved by the board of directors, which was advised by
experienced and independent legal counsel and financial advisors, and based its
approval, in part, on the approval and recommendation of the oversight
committee. In particular, Christian Dalloz and Daniel U. S. Sub believe that the
merger is fair to the Bacou USA stockholders who are unaffiliated with Bacou
S.A., because (1) of the integrity of the procedures implemented by the
oversight committee, including retaining its own advisors, receiving a fairness
opinion from UBS Warburg and active negotiations with Christian Dalloz, each of
which contributed to the original offer price being increased and (2) the $28.50
per share merger consideration is higher than the highest offer of $25.00 per
share resulting from the auction process. Christian Dalloz and Daniel U. S. Sub,
however, have a conflict of interest with respect to the merger agreement and
the merger, in that it is the other party to the merger agreement and will
acquire all the shares of common stock held by the Bacou USA stockholders, other
than Bacou S.A. and its affiliates, if the merger is consummated.

                                       53
<Page>
CHRISTIAN DALLOZ' REASONS FOR THE MERGER

    In determining to acquire the shares of the Bacou USA stockholders, other
than Bacou S.A. and its affiliates, and enter into the related acquisitions of
Engineering Henri Bacou and Bacou S.A., Christian Dalloz focused on a number of
factors. Specifically, Christian Dalloz believes that the merger, in conjunction
with the related acquisitions, would, among other things:

    - facilitate Christian Dalloz' development of a more consistent and flexible
      global presence in the protective equipment industry;

    - strengthen Christian Dalloz' position in its core business of protective
      equipment;

    - enhance Christian Dalloz' presence in the U.S. market and increase
      investment in, and the proportion of its earnings from, U.S. activities;

    - enable Christian Dalloz to develop synergies between Christian Dalloz and
      Bacou S.A. and achieve a consistent business organization among the
      combined entity's various businesses worldwide;

    - create a deeper and more diverse management group with a more efficient
      capital structure; and

    - represent a good use of Christian Dalloz' available funds relative to
      alternative investments.

PURPOSE AND STRUCTURE OF THE MERGER

    The purpose of the merger is to effect the acquisition by Christian Dalloz
of all the common stock of Bacou USA as part of the acquisition of the entire
Bacou Group. Christian Dalloz has undertaken the merger for the reasons stated
under "SPECIAL FACTORS--Christian Dalloz' Reasons for the Merger." In the
merger, each share of Bacou USA common stock (other than shares held by Bacou
S.A. and its affiliates) will be converted into the right to receive an amount
in cash equal to $28.50, without interest. The transaction is being undertaken
at this time because the Bacou Group determined to conduct an auction for all or
a portion of the Bacou Group in July 2000 for the reasons set forth under
"SPECIAL FACTORS--Background of the Merger and the Related Acquisition
Transactions."

    The acquisition of the Bacou USA common stock has been structured as a cash
merger in order to accomplish the acquisition in a single step, without the
necessity of financing separate purchases of shares in a tender offer or in open
market purchases while at the same time not materially disrupting Bacou USA's
operations. Christian Dalloz did not consider any alternative means to
accomplish the purposes set forth above because the merger is the most direct
means for effecting the acquisition of the shares of Bacou USA common stock.

    Following the merger, the common stock of Bacou USA will be delisted from
the New York Stock Exchange and the registration of the common stock under the
Securities Exchange Act of 1934 will be terminated. See "SPECIAL FACTORS--Plans
for Bacou USA after the Merger" and "SPECIAL FACTORS--Certain Effects of the
Merger."

CERTAIN EFFECTS OF THE MERGER

    If the merger is consummated, the holders of Bacou USA common stock, other
than Bacou S.A. and its affiliates, will no longer have any interest in, and
will not be stockholders of, Bacou USA and, therefore, will not benefit from any
future earnings or growth of Bacou USA or benefit from any increases in the
value of Bacou USA and will no longer bear the risk of any decreases in value of
Bacou USA. Instead, each such holder will have the right to receive upon
consummation of the merger $28.50 in cash, without interest, for each share of
Bacou USA common stock held. As a result of the merger, Christian Dalloz will
have 100% of the interests in Bacou USA's net book value and net earnings and
will be entitled to all the benefits resulting from such interest including all
income generated by Bacou USA's operations and any future increases in our
value. Christian Dalloz will also

                                       54
<Page>
bear the risk of losses generated by our operations and any future decrease in
our value after the merger.

    The Bacou USA common stock is currently registered under the Securities
Exchange Act of 1934. As a result of the merger, the common stock will be
delisted from the New York Stock Exchange, the registration of the common stock
under the Securities Exchange Act of 1934 will be terminated, Bacou USA will be
relieved of the obligation to comply with the proxy rules of Regulation 14A
under Section 14 of the Securities Exchange Act of 1934, and its officers,
directors and beneficial owners of more than 10% of the common stock will be
relieved of the reporting requirements and restrictions on insider trading under
Section 16 of the Securities Exchange Act of 1934. Further, Bacou USA will no
longer be subject to the periodic reporting requirements of the Securities
Exchange Act of 1934 and will cease filing information with the Securities
Exchange Commission. Accordingly, less information will be required to be made
publicly available than presently is the case.

PLANS FOR BACOU USA AFTER THE MERGER

    Christian Dalloz intends, subject to certain conditions, including receipt
of all necessary regulatory approvals, to consummate the acquisitions of
Engineering Henri Bacou and Bacou S.A. simultaneously with or promptly following
the merger. Christian Dalloz and Bacou S.A. will analyze how best to integrate
the management of the two entities after consummation of the merger and the
related transactions.

    Except as indicated in this information statement, Christian Dalloz does not
have any present plans or proposals which relate to, or would result in, an
extraordinary corporate transaction, such as a merger, reorganization or
liquidation involving Bacou USA or any of its subsidiaries, sale or transfer of
a material amount of assets of Bacou USA's or any other material changes in
Bacou USA's capitalization, dividend policy, corporate structure, business or
composition of the board of directors or the management of Bacou USA, except
that Christian Dalloz intends to review the composition of the board of
directors (or similar governing bodies) of Bacou USA and its subsidiaries and to
cause the election to such boards of directors (or similar governing bodies) of
certain of its representatives. It is anticipated, however, that Christian
Dalloz will from time to time evaluate and review its businesses, operations and
properties and make such changes as are deemed appropriate.

INTERESTS OF CERTAIN PARTIES IN THE MERGER AND RELATED ACQUISITION TRANSACTIONS;
  POTENTIAL CONFLICTS OF INTEREST

    You should be aware that, in addition to the matters discussed above, some
of our executive officers and certain members of our board of directors have
various interests in the merger described in this section that are in addition
to, or different from, the interests of our stockholders generally and create
potential conflicts of interest.

OPTIONS TO PURCHASE COMMON STOCK OF BACOU USA

    EXECUTIVE OFFICERS

    As of the effective time of the merger, all outstanding options to purchase
common stock will become fully vested. The merger agreement provides that, for
each share covered by outstanding stock options at the time of the merger, the
executive officers will have the right to receive a cash payment equal to the
difference between the $28.50 per share merger consideration and the per share
exercise price of such options, referred to as the "spread," reduced by
applicable withholding tax.

                                       55

    The following table summarizes the total number of shares covered by
options, and the number of such options that are currently held, vested and
unvested, by each executive officer, and all executive officers as a group, as
well as the aggregate amount to which each executive officer and the executive
officers as a group would be entitled if they elected to receive the spread for
all of their options as of the date of this information statement:

*   No performance objectives have been established.

**  Consists of options to purchase shares of Christian Dalloz at a price equal
    to the higher of 77 Euro or the average stock price of Christian Dalloz over
    the 20 trading days preceding the date of grant multiplied by 0.8, subject
    to the stock option plan generally applicable to top executives of Christian
    Dalloz including vesting (30% service options, 70% performance options). No
    performance targets have been established.

*** Constitutes signing bonus, up-front guaranteed 2001 bonus, up-front
    non-compete payment and up-front non-solicitation payment.

                                       59
<Page>
    Additionally, Mr. Barr, Mr. Bennett and Mr. Hebert would be entitled to
receive, respectively, options to purchase 0.833%, 0.488% and 0.488% of the
aggregate number of new shares of Christian Dalloz stock to be granted at an
exercise price equal to the price of the first public offering, if any, of
Christian Dalloz stock following completion of the merger agreement and the
related acquisition transactions. These options would be granted at the time of
such initial public offering and would be subject to the terms of the stock
option plan generally applicable to top executives of Christian Dalloz. Thirty
percent of the stock options to be granted upon completion of the merger and the
related acquisition transactions will constitute performance options.

    Messrs. Barr, Bennett and Hebert also received the following information
regarding the stock options which information is not included in their
respective letter agreements with Christian Dalloz. The exact terms and
conditions of the stock option grants and the stock option plan have not yet
been finalized and are subject to further negotiation and agreement by the
parties. The stock options granted to Mr. Barr, Mr. Bennett and Mr. Hebert would
vest after four years and would have a life of six years. They would be subject
to further exercise restrictions in order to spread exercise rights over the
four to six year period. The options would be forfeited in the event of
resignation or termination of the executive for cause. In the event of
termination of the executive other than for cause, within four years of
employment, service options would vest proportionally to the time of employment
with Christian Dalloz since the closing date of the merger but performance
options would be forfeited. All options would accelerate in the event of change
of control of Christian Dalloz only if the executive is prejudiced by such
change of control (that is, he is demoted, terminated or his benefits are
decreased). The specific terms and conditions of these options have not been
finalized and are the subject of ongoing discussions among the affected parties.

    The employment agreements will be for an indefinite term and will be further
negotiated by the parties prior to the closing of the merger. However, no formal
employment agreements have been proposed or executed between the parties and
therefore employment terms remain subject to completion and acceptance by the
parties.

    Christian Dalloz expects to enter into a consulting agreement with
Mr. Walter Stepan on the terms set forth in the letter agreement between
Christian Dalloz and Mr. Stepan dated May 29, 2001. Mr. Stepan's expected duties
under the consulting agreement, among others, are to provide advice with respect
to acquisition opportunities, the non-prescription protective eyewear business
of the combined business and various contractual relationships between Bacou USA
and Bacou S.A., on the one hand, and Uvex Germany, on the other. Pursuant to the
terms of such letter agreement, which are subject to further negotiation and
execution of a definitive consulting agreement, the consulting agreement would
be for a period of two years. Pursuant to the consulting agreement, Mr. Stepan
would receive $340,000 upon closing of the merger and the related acquisition
transactions, $80,000 upon the first anniversary of the closing and $80,000 upon
the second anniversary of the closing. The letter agreement provides that the
consulting agreement will contain customary terms relating to non-competition,
non-solicitation and confidentiality.

SHARE OPTION PURCHASE AGREEMENT

    On July 8, 2000, in anticipation of a contemplated sale of Bacou S.A., Mevra
Beheer BV, a Netherlands company controlled by Vandeputte International NV,
Protection Participation, Hobar Corporation BV, and Sauvegarde entered into a
Share Option Purchase Agreement pursuant to which Mevra Beheer granted to
Protection Participation, Hobar Corporation and Sauvegarde an irrevocable option
to purchase an aggregate of 470,953 shares of Bacou S.A. owned by Mevra Beheer,
representing approximately 38% of the outstanding shares of Bacou S.A. On
September 1, 2000, the beneficiaries of the Share Option Purchase Agreement
exercised their respective options. On April 24, 2001 and again on May 29, 2001
certain provisions of the Share Option Purchase Agreement were amended to effect
a reduction in the purchase price for the option and to extend the time by which
a sale of the Bacou

                                       60
<Page>
Group could occur before Sauvegarde, Protection Participation and Hobar
Corporation would be required to redeliver to Mevra Beheer BV the Bacou S.A.
shares that they had purchased pursuant to the Share Option Purchase Agreement
and forfeit their deposit. As initial consideration for the grant of the option,
the beneficiaries of the option grant paid a non-refundable deposit aggregating
35,000,000 French francs ($4,559,904). Sauvegarde paid 14,000,000 French francs
($1,823,962) of such deposit. On May 29, 2001, Protection Participation and
Hobar Corporation paid 55,000,000 French francs ($7,165,563) with respect to
34,249 option shares thereby completing payment for such option shares. The
Share Option Purchase Agreement, as amended, provides that in the event of a
sale of Bacou S.A., the beneficiaries will pay to Mevra Beheer BV the aggregate
balance of the purchase price of 753,185,214 French francs ($98,127,210) plus
interest with respect to 436,704 option shares.

    The price per share to be paid by Sauvegarde for the Bacou S.A. shares to be
purchased pursuant to the Share Option Purchase Agreement is 1,804.84 French
francs ($235) per share. This compares to a price of 2,787.2 French francs
($363) per share to be received for the sale of these shares to Christian
Dalloz.

INDEMNIFICATION AND INSURANCE

    The merger agreement provides that the surviving corporation will assume all
responsibility for all provisions with respect to indemnification of directors
and officers as set forth in Bacou USA's certificate of incorporation and
by-laws and will maintain in effect the current directors' and officers'
liability insurance or substantially similar insurance covering those persons
who are currently covered on the date of the merger agreement by our directors'
and officers' liability insurance policy for a period of six years. The merger
agreement also provides that Christian Dalloz and the surviving corporation will
indemnify and hold harmless any former or current officer or director of Bacou
USA against any losses in connection with any threatened or actual action, suit
or proceeding, based in whole or in part on, or arising in whole or in part out
of, the fact that the person is or was an officer or director of Bacou USA.

MATERIAL U.S. FEDERAL INCOME TAX CONSEQUENCES OF THE MERGER TO OUR STOCKHOLDERS

    The following is a summary of all of the material U.S. federal income tax
consequences of the merger to holders of shares who dispose of such shares in
the merger, who are United States Persons (as defined below), and who, on the
date of disposition, hold such shares as capital assets (as defined in the
Internal Revenue Code of 1986, as amended) (each, a "United States Holder").
This discussion is based on the Internal Revenue Code, proposed and final United
States Treasury Regulations issued under the Internal Revenue Code, and
administrative and judicial interpretations of the Internal Revenue Code and the
United States Treasury Regulations issued under the Internal Revenue Code, each
as in effect and available on the date of this information statement. All of the
foregoing are subject to change, which change would apply retroactively and
could affect the tax consequences described below.

    We urge all holders to consult their own tax advisors regarding the specific
tax consequences that may result from their individual circumstances as well as
foreign, state and local tax consequences of the disposition of shares in the
merger. Except as specifically noted otherwise, this summary does not address
potential foreign, state, local and other tax consequences, nor does it address
special tax consequences that may be applicable to particular classes of
taxpayers, including financial institutions, real estate investment trusts,
regulated investment companies, brokers and dealers or traders in securities or
currencies, persons whose functional currency is not the U.S. dollar, insurance
companies, tax-exempt organizations, S corporations, persons who hold common
stock as part of a position in a "straddle" or as part of a "hedging" or
"conversion" transaction for U.S. federal income tax purposes, persons who
acquired common stock pursuant to an exercise of employee stock options or
rights or otherwise as compensation, persons who hold employee stock options or
rights to acquire common stock and persons that own (or are deemed to own) 10%
or more (by voting power or value) of the stock of Bacou USA. Moreover, this
summary does not address the U.S. federal estate and gift or alternative minimum
tax consequences of the merger.

    A "United States Person" is a beneficial owner of common stock of Bacou USA,
who for U.S. federal income tax purposes is: (1) a citizen or resident of the
U.S., including some former citizens or residents of the U.S.; (2) a partnership
or corporation created or organized in or under the laws of the U.S. or any
state thereof, including the District of Columbia; (3) an estate if its income
is subject to U.S. federal income taxation regardless of its source; or (4) a
trust if such trust validly has elected to be treated as a United States person
for U.S. federal income tax purposes or if (a) a court within the U.S. is able
to exercise primary supervision over its administration and (b) one or more
United States persons have the authority to control all of its substantial
decisions.

    A United States Holder generally will realize gain or loss upon the
surrender of such holder's shares pursuant to the merger in an amount equal to
the difference, if any, between the amount of cash received and such United
States Holder's aggregate adjusted tax basis in the shares surrendered in
exchange therefor.

    In general, any gain or loss realized by a United States Holder in the
merger will be eligible for capital gain or loss treatment. In the case of a
noncorporate United States Holder, the maximum marginal U.S. federal income tax
rate applicable to such gain will be lower than the maximum marginal U.S.
federal income tax rate applicable to ordinary income if such United States
Holder's holding period for such shares exceeds one year and will be further
reduced if such holding period exceeds five years. Gain or loss, if any,
recognized by a United States Holder generally will be treated as U.S. source
income or loss for U.S. foreign tax credit purposes. The deductibility of
capital losses is subject to limitations.

                                       64
<Page>
    For corporations, a capital gain is subject to U.S. federal income tax at a
maximum rate of 35% while any capital loss can be offset only against other
capital gains. Any unutilized capital loss generally can be carried back three
years and forward five years to be offset against net capital gains generated in
such years.

    Each holder of a compensatory option to acquire shares who receives a cash
payment equal to the spread on such stock option will have ordinary income to
the extent of the cash received or treated as received (including any applicable
withholding taxes) unless a timely election was made by such holder to include
the value of the option in such holder's taxable income on the grant date.

    U.S. backup withholding tax and information reporting requirements generally
apply to certain payments to certain noncorporate holders of stock. Information
reporting generally will apply to proceeds from the surrender of shares pursuant
to the merger made within the U.S. to a holder of shares (other than an "exempt
recipient", including a corporation, a payee that is not a U.S. person that
provides an appropriate certification and certain other persons). A payor will
be required to withhold 31% of the proceeds from the surrender of shares
pursuant to the merger within the U.S. to a holder (other than an "exempt
recipient") if such holder fails to furnish its correct taxpayer identification
number or otherwise fails to comply with, or establish an exemption from, such
backup withholding tax requirements.

    In the case of such payments made within the U.S. to a foreign simple trust,
a foreign grantor trust or a foreign partnership (other than payments to a
foreign simple trust, a foreign grantor trust or a foreign partnership that
qualifies as a "withholding foreign trust" or a "withholding foreign
partnership" within the meaning of such United States Treasury Regulations and
payments to a foreign simple trust, a foreign grantor trust or a foreign
partnership that are effectively connected with the conduct of a trade or
business in the United States), the beneficiaries of the foreign simple trust,
the persons treated as the owners of the foreign grantor trust or the partners
of the foreign partnership, as the case may be, will be required to provide the
certification discussed above in order to establish an exemption from backup
withholding tax and information reporting requirements. Moreover, a payor or
middleman may rely on a certification provided by a payee that is not a U.S.
person only if such payor or middleman does not have actual knowledge or a
reason to know that any information or certification stated in such certificate
is incorrect.

    THE U.S. FEDERAL INCOME TAX CONSEQUENCES SET FORTH ABOVE ARE NOT INTENDED TO
CONSTITUTE A COMPLETE DESCRIPTION OF ALL TAX CONSEQUENCES RELATING TO THE
MERGER. EACH HOLDER OF SHARES IS URGED TO CONSULT HIS OR HER OWN TAX ADVISOR TO
DETERMINE THE PARTICULAR TAX CONSEQUENCES TO SUCH STOCKHOLDER OF THE MERGER,
INCLUDING THE APPLICABILITY AND EFFECT OF FOREIGN, STATE, LOCAL AND OTHER TAX
LAWS.

THE GLOBAL TRANSACTION

    OVERVIEW

    The merger is part of a global transaction pursuant to which the business of
Christian Dalloz will be combined with the business of the Bacou Group. The
Bacou Group includes Bacou USA, Bacou S.A. (our majority stockholder), and its
parent company, Engineering Henri Bacou. Bacou S.A. and Engineering Henri Bacou
are privately held companies, which, in addition to their direct and indirect
equity ownership of Bacou USA, manufacture and distribute personal protection
equipment and other products principally in Western Europe. The combination will
occur by virtue of the merger and the acquisition by Christian Dalloz of all of
the shares of Bacou S.A. and Engineering Henri Bacou. The results of the merger
and these related transactions are (1) Christian Dalloz will acquire 100%
ownership of the Bacou Group, (2) Christian Dalloz will change its name to
Bacou-Dalloz, (3) the shareholders of Bacou S.A. and Engineering Henri Bacou,
including the Bacou family and Sauvegarde LLC (an entity owned by certain
members of our senior management), will receive in exchange for their shares of
Bacou S.A. and Engineering Henri Bacou cash in the aggregate amount of

                                       65
<Page>
approximately 1.7 billion French francs ($221,481,057) and 2,906,392 million
shares of Christian Dalloz representing approximately 40% of the shares of
Bacou-Dalloz following the combination, (4) Bacou USA will become a wholly owned
subsidiary of Christian Dalloz and (5) Bacou USA's minority stockholders will
have the right to receive $28.50 per share in cash.

    In order to increase the liquidity of the Christian Dalloz shares received
by the Bacou family, the parties agreed that a total of 918,694 of Christian
Dalloz shares could be sold by members of the Bacou family to investors in
Christian Dalloz for aggregate cash consideration of 394,020,296 French francs
($51,334,136). This agreement includes 141,600 shares that will be sold to
Sauvegarde for aggregate cash consideration of 71,520,304 French francs
($9,317,878).

    As a result of the related acquisitions of Bacou S.A. and Engineering Henri
Bacou, these two companies will become subsidiaries of Christian Dalloz.

    The following charts set forth the structure of the Bacou Group and
Christian Dalloz group prior to and following the merger and the related
acquisition transactions:

    The aggregate equity value of the Bacou Group (including Bacou USA) as
negotiated by the Bacou family and Christian Dalloz, is $596,900,000 (assuming
exchange rates of 7.3 French francs/$1.00 and 1.113 Euro/$1.00, which exchange
rates were agreed upon by the parties in connection with the valuation of the
transaction, and assuming that the Christian Dalloz shares are valued at 77
Euro). There are 5,069,065 Bacou USA shares outstanding that are held by
stockholders other than Bacou S.A. At a price of $28.50 per share these
stockholders will be entitled to receive an aggregate of $144,468,352.50 of
merger consideration. Accordingly, the aggregate equity value of the Bacou Group
(including the shares of Bacou USA owned by Bacou S.A. with an aggregate value
of $359,459,100 based on the $28.50 merger consideration) allocable to the
stockholders of Bacou S.A. and Engineering Henri Bacou is $452,432,000. This
information has been provided for convenience only. Bacou USA believes that
Bacou S.A. and Bacou USA are not directly comparable entities.

    FINANCING OF THE GLOBAL TRANSACTION

    Christian Dalloz plans to fund the merger and the related acquisitions of
Bacou S.A. and Engineering Henri Bacou and to pay all related fees and expenses
through a combination of cash on hand and debt provided by BNP Paribas and J.P.
Morgan plc. The completion of the merger and the related acquisition
transactions is conditioned on Christian Dalloz obtaining financing
substantially in accordance with the commitment letter and term sheets received
from BNP Paribas and J.P. Morgan.

    The commitment letter and term sheets, received by Christian Dalloz on
May 29, 2001, indicate the commitment of BNP Paribas and J.P. Morgan, as joint
lead arrangers, to arrange four senior secured credit facilities, totaling
2,697 million French francs ($351,373,183) and $291 million, for the purpose of
effecting the merger and the related acquisition transactions. Of this amount,
627.8 million French francs ($81,791,652) constitutes a five-year multicurrency
revolving group facility. The balance is divided into three term loans, each
with a five-year maturity. The final maturity date for each of the facilities is
June 30, 2006.

    The interest rate for these credit facilities will be LIBOR or EURIBOR,
respectively, for U.S. or European currency, plus an applicable margin of
1.550%, adjusted on a quarterly basis, that varies with the leverage ratio of
Christian Dalloz. Interest will payable on the three term loans every six
months.

    Loans under the credit facilities will be guaranteed by an unconditional
first demand guarantee from Christian Dalloz and unconditional guarantees from
Bacou S.A. and certain subsidiaries of Christian Dalloz and Bacou S.A.,
including Bacou USA. Such loans will be secured by, among other things, shares
of certain material subsidiaries and Bacou S.A., and a U.S. general security
agreement over the assets of Bacou USA and Dalloz Safety Inc., a U.S. subsidiary
of Christian Dalloz.

    The commitments to arrange, and the availability of, the credit facilities
are subject to customary conditions, including the execution and delivery of
definitive documentation, receipt of relevant financial statements from the
parties involved, receipt of legal and tax opinions related to the global
transaction, the veracity of certain representations and warranties made by
Christian Dalloz, and the payment of fees, costs and expenses in accordance with
the terms of the commitment and fee letters.

                                   THE MERGER

    The following information describes the material aspects of the merger. This
description does not purport to be complete and is qualified in its entirety by
reference to the appendices hereto, including the merger agreement which is
attached to this information statement as Appendix A and is incorporated herein
by reference. You are urged to read Appendix A in its entirety. See also "THE
MERGER--The Merger Agreement" below.

    Our board of directors has determined, after considering the unanimous
recommendation of the oversight committee, that the merger is fair to and our
public stockholders and has declared that the merger agreement and the merger
are advisable and in the best interests of Bacou USA and its stockholders, other
than Bacou S.A. and its affiliates. See "SPECIAL FACTORS--Reasons for the
Approval of the Oversight Committee and our Board of Directors."

EFFECTIVE TIME OF MERGER

    If the conditions to the merger are satisfied (or waived to the extent
permitted), the merger will be consummated and become effective at the time a
duly executed certificate of merger is filed with the Secretary of State of the
State of Delaware, or at such later time as otherwise agreed by Christian Dalloz
and Bacou USA and as specified in the certificate of merger. The filing will
occur after all conditions to the merger contained in the merger agreement have
been satisfied or waived. We expect to complete the merger on or before
September 6, 2001.

    The merger agreement may be terminated prior to the effective time of the
merger by Bacou USA or Christian Dalloz in certain circumstances, whether before
or after the adoption of the merger agreement by Bacou USA stockholders. See
"THE MERGER--The Merger Agreement--Termination of the Merger Agreement."

PAYMENT OF MERGER CONSIDERATION AND SURRENDER OF STOCK CERTIFICATES

    Christian Dalloz will designate an agent to act as paying agent for purposes
of making the cash payments contemplated by the merger agreement. Immediately
prior to the effective time of the merger, Christian Dalloz will deposit in
trust with the paying agent cash in United States dollars in an aggregate amount
equal to the merger consideration for all outstanding shares held by
stockholders except for our subsidiaries, and Bacou S.A. or shares held in our
treasury. The paying agent will, pursuant to irrevocable instructions, deliver
to you your merger consideration according to the procedure summarized below.

    At the close of business on the day of the effective time of the merger our
stock ledger with respect to common stock will be closed.

    As soon as reasonably practicable after the effective time of the merger,
the paying agent will mail to you a letter of transmittal and instructions
advising you of the procedure for surrendering to the paying agent your
certificates in exchange for the merger consideration. Upon the surrender for
cancellation to the paying agent of your certificates, together with a letter of
transmittal affixed, executed and completed in accordance with its instructions,
and any other items specified by the letter of transmittal, the paying agent
will pay to you your merger consideration. No interest will be paid or accrued
in respect of cash payments of merger consideration.

    If the merger consideration (or any portion of it) is to be delivered to a
person other than you, it will be a condition to the payment of the merger
consideration that your certificates be properly endorsed or accompanied by
appropriate stock powers and otherwise in proper form for transfer, that the
transfer otherwise be proper and not violate any applicable federal or state
securities laws, and that you pay to the paying agent any transfer or other
taxes payable by reason of the transfer or establish to the satisfaction of the
paying agent that the taxes have been paid or are not required to be paid.

                                       69
<Page>
    YOU SHOULD NOT FORWARD YOUR STOCK CERTIFICATES TO THE PAYING AGENT WITHOUT A
LETTER OF TRANSMITTAL, AND YOU SHOULD NOT RETURN YOUR STOCK CERTIFICATES PRIOR
TO YOUR RECEIPT OF THE LETTER OF TRANSMITTAL.

    At and after the effective time of the merger, you will cease to have any
rights as our stockholder, except for the right to surrender your certificate in
exchange for payment of the merger consideration or, if you exercise your
appraisal rights, the right to perfect your right to receive payment for your
shares pursuant to Delaware law, and no transfer of common stock will be made on
the stock transfer books of the surviving corporation. Certificates presented to
the surviving corporation after the effective time will be canceled and
exchanged for cash as described above.

    Promptly following the date which is nine months after the effective date of
the merger, the paying agent will return to Christian Dalloz any undistributed
portion of the merger consideration, and the paying agent's duties will
terminate. Thereafter, stockholders may surrender their certificates to
Christian Dalloz and (subject to applicable abandoned property laws, laws
regarding property which is not accounted for by the laws of intestacy and
similar laws) receive the merger consideration without interest, but will have
no greater rights against Christian Dalloz than may be accorded to general
creditors of Christian Dalloz under applicable law. None of the paying agent,
Bacou USA, Christian Dalloz or Daniel U. S. Sub will be liable to stockholders
for any merger consideration delivered to a public official pursuant to
applicable abandoned property laws, laws regarding property which is not
accounted for by the laws of intestacy and similar laws.

ACCOUNTING TREATMENT

    After completion of the global transactions, Bacou USA will be a wholly
owned subsidiary of a French company. Bacou USA will not be required to comply
with U.S. GAAP; rather, it will be considered part of a consolidated group under
French GAAP.

FINANCING OF THE MERGER; FEES AND EXPENSES OF THE MERGER

    Christian Dalloz plans to fund the merger and the related acquisitions of
Bacou S.A. and Engineering Henri Bacou and to pay related fees and expenses
through a combination of cash on hand and debt provided by BNP Paribas and
J.P. Morgan plc. The French transactions are conditioned on Christian Dalloz
obtaining the proceeds of financings committed by BNP Paribas and J.P. Morgan
plc or obtaining other financing sufficient to complete the merger. See "SPECIAL
FACTORS--The Global Transaction--Financing of the Global Transaction" and
"SPECIAL FACTORS--The Global Transaction--Fees and Expenses."

APPRAISAL RIGHTS

    Pursuant to Delaware law, you are entitled to appraisal rights under
Section 262 of the General Corporation Law of the State of Delaware in
connection with the merger.

    SECTION 262 IS REPRINTED IN ITS ENTIRETY AS APPENDIX C TO THIS INFORMATION
STATEMENT. THE FOLLOWING DISCUSSION IS NOT A COMPLETE STATEMENT OF THE LAW
RELATING TO APPRAISAL RIGHTS AND IS QUALIFIED IN ITS ENTIRETY BY REFERENCE TO
APPENDIX C. THIS DISCUSSION AND APPENDIX C SHOULD BE REVIEWED CAREFULLY BY YOU
IF YOU WISH TO EXERCISE STATUTORY APPRAISAL RIGHTS OR YOU WISH TO PRESERVE THE
RIGHT TO DO SO, AS FAILURE TO COMPLY WITH THE PROCEDURES SET FORTH IN
SECTION 262 WILL RESULT IN THE LOSS OF YOUR APPRAISAL RIGHTS.

    If you make the demand described below with respect to your shares, you are
continuously the record holder of your shares through the effective time of the
merger, and otherwise comply with the statutory requirements of Section 262, you
shall be entitled to an appraisal by the Delaware Court of Chancery of the "fair
value" of your shares exclusive of any element of value arising from the

                                       70
<Page>
accomplishment or expectation of the merger, together with a fair rate of
interest, as determined by the Delaware Court of Chancery.

    Under Section 262, where a merger is approved by the written consent of the
stockholders pursuant to Section 228 of the General Corporation Law of the State
of Delaware, as in the case of the adoption of the merger agreement by Bacou
USA's stockholders, the corporation, either before the effective date of the
merger or within ten days thereafter, must notify each of its stockholders
entitled to appraisal rights that such appraisal rights are available and
include in such notice a copy of Section 262. This information statement shall
constitute such notice to the Bacou USA stockholders, and the applicable
statutory provisions are attached to this information statement as Appendix C.
If such notice is given after the effective date of the merger, such notice must
also notify such stockholders of the effective date of the merger. If such
notice is given before the effective date of the merger, as in the case of Bacou
USA, the corporation must provide a second notice to those persons entitled to
appraisal rights within 10 days after the effective date of the merger,
notifying them of the effective date of the merger.

    If you desire to exercise your appraisal rights you must deliver a separate
written demand for appraisal to us within 20 days after the date of the mailing
of this information statement which constitutes notice of your appraisal rights.

    Only a holder of record is entitled to assert appraisal rights for the
shares of our common stock registered in that holder's name. A demand for
appraisal must be executed by or on behalf of the holders of record and must
reasonably inform us of the identity of the holder of record and that the holder
of record intends to demand appraisal of the holder's shares. If you have a
beneficial interest in shares that are held of record in the name of another
person, such as a broker, fiduciary or other nominee, you must act promptly to
cause the record holder to perfect whatever appraisal rights are available
properly and in a timely manner, and your demand must be executed by or for the
record owner. If your shares are owned of record by more than one person, as in
a joint tenancy or tenancy in common, your demand must be executed by or for all
joint owners. An authorized agent, including an agent for two or more joint
owners, may execute the demand for appraisal; however, the agent must identify
the record owner and expressly disclose the fact that, in exercising the demand,
the agent is acting as agent for the record owner.

    A record owner, such as a broker, fiduciary or other nominee, who holds
shares as a nominee for others, may exercise appraisal rights with respect to
the shares held for all or less than all beneficial owners of shares as to which
the person is the record owner. In such case, the written demand must set forth
the number of shares covered by the demand. Where the number of shares is not
expressly stated, the demand will be presumed to cover all shares in the name of
such record owner.

    A Bacou USA stockholder wishing to exercise appraisal rights must, within
20 days after the date of mailing of this information statement, make a written
demand for the appraisal of such stockholder's shares to Bacou USA. If you elect
to exercise appraisal rights, you should mail or deliver your written demand to:
Bacou USA, Inc., 10 Thurber Boulevard, Smithfield, Rhode Island, 02917-1896,
Attention: Corporate Secretary.

    The written demand for appraisal should specify your name and mailing
address, the number of shares owned, and that you are demanding appraisal of
your shares. Within ten days after the effective time of the merger, the
surviving corporation in the merger must provide notice of the effective time of
the merger to you if you have complied with Section 262.

    Within 120 days after the effective date of the merger, either the surviving
corporation or you, if you have complied with the required conditions of
Section 262 and are otherwise entitled to appraisal rights, may file a petition
in the Delaware Court of Chancery, and if you file a petition you must serve a
copy on the surviving corporation, demanding a determination of the fair value
of the shares of all

                                       71
<Page>
stockholders demanding an appraisal. Bacou USA does not have any present
intention to file any such petition in the event that a stockholder makes a
written demand. Accordingly, if you desire to have your shares appraised, you
should initiate any petitions necessary for the perfection of your appraisal
rights within the time periods and in the manner prescribed in Section 262. If
appraisal rights are available, and if you have complied with the applicable
provisions of Section 262, within 120 days after the effective date of the
merger you will be entitled, upon written request, to receive from the surviving
corporation in the merger a statement setting forth the aggregate number of
shares not voting in favor of the merger agreement and with respect to which we
received demands for appraisal, and the aggregate number of holders of such
shares. The statement must be mailed within 10 days after the written request
for the statement has been received by the surviving corporation or within
10 days after the expiration of the period for delivery of demands for appraisal
rights whichever is later.

    If a petition for an appraisal is timely filed by a holder of our shares and
a copy thereof is served upon the surviving corporation, the surviving
corporation will then be obligated within 20 days to file with the Delaware
Register in Chancery a duly verified list containing the names and addresses of
all stockholders who have demanded an appraisal of their shares of common stock
and with whom agreements as to the value of their shares have not been reached.
After notice to those stockholders as required by the Court, the Delaware Court
of Chancery is empowered to conduct a hearing on the petition to determine those
stockholders who have complied with Section 262 and who have become entitled to
appraisal rights thereunder. If you have demanded an appraisal, the Delaware
Court of Chancery may require you to submit your certificates to the Register in
Chancery for notation on the certificates of the pendency of the appraisal
proceeding; and if you fail to comply with the direction, the Delaware Court of
Chancery may dismiss the proceedings as to you. Where proceedings are not
dismissed, the Delaware Court of Chancery will appraise the shares owned by
stockholders demanding an appraisal, determining the "fair value" of such
shares, together with a fair rate of interest, if any, to be paid upon the
amount determined to be the fair value. In such event, the Delaware Court of
Chancery's appraisal may be more than, less than, or equal to the merger
consideration, and stockholders should be aware that an investment advisor's
opinions as to fairness from a financial point of view are not necessarily
opinions as to "fair value" under Section 262. In determining fair value, the
Delaware Court of Chancery is to take into account all relevant factors. In
relevant case law, the Delaware Supreme Court discussed the factors that could
be considered in determining fair value in an appraisal proceeding, stating that
"proof of value by any techniques or methods which are generally considered
acceptable in the financial community and otherwise admissible in court" should
be considered, and that "fair price obviously requires consideration of all
relevant factors involving the value of a company." The Delaware Supreme Court
also stated that "elements of future value, including the nature of the
enterprise, which are known or susceptible of proof as of the date of the merger
and not the product of speculation, may be considered." Section 262, however,
provides that fair value is to be "exclusive of any element of value arising
from the accomplishment or expectation of the merger." In addition, Delaware
courts have decided that the statutory appraisal remedy, depending on factual
circumstances, may or may not be a dissenting stockholder's exclusive remedy.

    The Court will also determine the amount of interest, if any, to be paid
upon the amounts to be received by persons whose shares of our common stock have
been appraised. The cost of the appraisal proceeding may be determined by the
Delaware Court of Chancery and taxed against the parties, as the Delaware Court
of Chancery deems equitable in the circumstances. Upon application of a
stockholder who has demanded an appraisal, the Delaware Court of Chancery may
order that all or a portion of the expenses incurred by any such stockholder in
connection with the appraisal proceeding, including, without limitation,
reasonable attorney's fees and the fees and expenses of experts, be charged pro
rata against the value of all shares of stock entitled to appraisal.

    If you have demanded appraisal in compliance with Section 262, you will not,
after the effective time of the merger, be entitled to vote for any purpose any
shares subject to your demand, or to

                                       72
<Page>
receive payment of dividends or other distributions on your shares, except for
dividends or distributions payable to holders of record as of a date prior to
the effective time of the merger.

    If you submit a written demand for appraisal, but no petition for appraisal
is filed with the Delaware Court of Chancery within 120 days after the effective
time of the merger, your rights to appraisal shall cease. If you submit a
written demand for appraisal, you may withdraw your demand for appraisal by
delivering to the surviving corporation a written withdrawal of your demand for
appraisal and an acceptance of the merger, except that (1) any attempt to
withdraw made more than 60 days after the effective time of the merger will
require written approval of the surviving corporation, and (2) no appraisal
proceeding in the Delaware Court of Chancery shall be dismissed without the
approval of the Delaware Court of Chancery, and the approval may be conditioned
upon such terms as the Delaware Court of Chancery deems just.

    IF YOU FAIL TO COMPLY FULLY WITH THE STATUTORY PROCEDURE SET FORTH IN
SECTION 262, YOU WILL FORFEIT YOUR RIGHTS OF APPRAISAL AND WILL BE ENTITLED TO
RECEIVE THE MERGER CONSIDERATION FOR YOUR SHARES.

    Because you are not being asked to vote to approve the merger agreement and
the merger, it is important that you consider whether or not to exercise
appraisal rights.

      such date neither Bacou USA nor any of its subsidiaries will have any more
      rights or liabilities thereunder.

    We also agreed that we will (1) confer with Christian Dalloz on a regular
and frequent basis to report on operational matters and other matters requested
by Christian Dalloz, and (2) promptly advise Christian Dalloz orally and in
writing of any change or event that would reasonably be expected to have a
material adverse effect on Bacou USA.

    Both Christian Dalloz and we will promptly provide the other copies of all
filings made by such party with any governmental entity in connection with the
merger agreement and the transactions

                                       76
<Page>
contemplated thereby, other than the portions of such filings that include
confidential information not directly related to the transactions contemplated
by the merger agreement.

NO SOLICITATION OF OTHER OFFERS

    The merger agreement provides that up to the effective time of the merger
neither we and our subsidiaries nor our representatives will:

    - directly or indirectly solicit, initiate or encourage the submission of
      any Company Takeover Proposal (as defined below);

    - enter into any agreement with respect to any Company Takeover Proposal; or

    - directly or indirectly participate in any discussions or negotiations
      regarding, or furnish to any person any information with respect to, or
      take any other action to facilitate any inquiries or the making of any
      proposal that constitutes, or may reasonably be expected to lead to, any
      Company Takeover Proposal.

    The merger agreement also provides that neither our board of directors nor
any committee of our board of directors may (1) withdraw or modify, or propose
to withdraw or modify, in a manner adverse to Christian Dalloz or Daniel U. S.
Sub, the approval or recommendation by our board of directors or any committee
of our board of directors of the merger agreement or the merger, (2) approve any
letter of intent, agreement in principle, acquisition agreement or similar
agreement relating to any Company Takeover Proposal or (3) approve or recommend,
or propose to approve or recommend, any Company Takeover Proposal. The merger
agreement provides, however, that if prior to receipt of our stockholder
approval, which has been obtained pursuant to the written consent of Bacou S.A.
(our majority stockholder) executed on August 3, 2001, our board of directors
receives a Superior Proposal (as defined below) and as a result of the Superior
Proposal the oversight committee determines in good faith, after receiving
advice from its outside legal counsel, that failure to take such action would
constitute a breach of the board of directors' fiduciary duties to the Bacou USA
stockholders under applicable law, then the oversight committee (and the board
of directors acting on the recommendation of the oversight committee) may
withdraw or modify its approval or recommendation of the merger agreement and
the merger and disclose such withdrawal or modification to the Bacou USA
stockholders.

    The merger agreement provides that we must promptly advise Christian Dalloz
of any Company Takeover Proposal or any inquiry regarding any Company Takeover
Proposal and the identity of the person making any such Company Takeover
Proposal or inquiry, including any change to the material terms of any such
Company Takeover Proposal or inquiry. We must (1) keep Christian Dalloz fully
informed of the status (including any change to the details) of any such Company
Takeover Proposal or inquiry and (2) provide to Christian Dalloz as soon as
practicable after receipt or delivery thereof with copies of all correspondence
and other written material sent or provided to Bacou USA from any third party in
connection with any Company Takeover Proposal or sent or provided by Bacou USA
to any third party in connection with any Company Takeover Proposal.

    "Company Takeover Proposal" means (1) any proposal or offer for a merger,
consolidation, dissolution, recapitalization or other business combination
involving Bacou USA, (2) any proposal for the issuance by Bacou USA of over 15%
of its equity securities as consideration for the assets or securities of
another person or (3) any proposal or offer to acquire in any manner, directly
or indirectly, over 15% of the equity securities or consolidated total assets of
Bacou USA, in each case other than the transactions contemplated by the merger
agreement and other than any acquisition transaction permitted by Section 5.01
of the merger agreement.

    "Superior Proposal" means any bona fide proposal to acquire, directly or
indirectly, for cash, all of the shares of Bacou USA common stock or all or
substantially all of the assets of Bacou USA to be followed by a pro rata
distribution of the sale proceeds to the stockholders of Bacou USA, that

                                       77
<Page>
(1) provides Bacou USA stockholders with per share consideration that the
oversight committee determines in good faith, after receipt of advice of its
financial advisor, is more favorable from a financial point of view than the
consideration to be received by Bacou USA stockholders in the merger, (2) is
determined by the oversight committee in its good faith judgment, after receipt
of advice of its financial advisor and outside legal counsel, to be likely of
being completed (taking into account all legal, financial, regulatory and other
aspects of the proposal, the person making the proposal and the expected timing
to complete the proposal), (3) does not, in the definitive acquisition
agreement, contain any "due diligence" conditions, and (4) has not been obtained
by or on behalf of Bacou USA in violation of its no-solicitation covenant.

    The merger agreement further stipulates that notwithstanding any provision
of the merger agreement to the contrary, Bacou USA's board of directors will be
permitted, to the extent applicable, to comply with Rule 14d-9 and
Rule 14e-2(a) promulgated under the Securities Exchange Act of 1934 with regard
to any Company Takeover Proposal, or make any other disclosure required by
applicable law, so long as any such disclosure rejects any Company Takeover
Proposal and reaffirms the recommendation of Bacou USA's board of directors of
the transactions contemplated by the merger agreement.

ACCESS TO INFORMATION

    Subject to the terms of a confidentiality agreement with Christian Dalloz,
we and our subsidiaries will afford to Christian Dalloz and its representatives
reasonable access to our and our subsidiaries' properties, books and records,
and furnish Christian Dalloz with all information concerning the business upon
reasonable notice.

      governmental authority prohibiting or restricting the merger, provided
      that prior to asserting this condition each of the parties shall have used

      order and to appeal as promptly as possible any such judgment that may be
      entered; and

    If the merger agreement is adopted by our stockholders, we do not anticipate
any other material uncertainty surrounding the merger conditions, and we expect
to complete the merger on or before July 31, 2001.

TERMINATION OF THE MERGER AGREEMENT

    The merger agreement may be terminated at any time prior to the effective
time of the merger, either prior to or after the adoption of the merger
agreement by the holders of a majority of all outstanding shares of common stock
as of the record date, by mutual written consent of Christian Dalloz, Daniel U.
S. Sub and Bacou USA.

    Either Christian Dalloz or Bacou USA may terminate the merger agreement if:

    - the merger is not completed on or before December 31, 2001, and the
      terminating party is not in breach of the merger agreement;

    - a governmental entity issues a final and non-appealable ruling permanently
      restraining or prohibiting the merger;

    - upon a vote at a duly held meeting to obtain Bacou USA stockholder
      approval such approval is not obtained; or

    - the agreements forming or governing the acquisition transactions related
      to the merger are terminated in accordance with their terms.

    Christian Dalloz may terminate the merger agreement if Bacou USA commits a
material breach of any covenant, representation or warranty in the merger
agreement, and such breach cannot be or has not been cured within 30 days after
the giving of written notice to Bacou USA of such breach.

    Upon termination, the merger agreement will become void and there shall be
no liability on the part of any party except as provided by the confidentiality
agreement, relating to access to information, and by the French master agreement
relating to fees and expenses incurred in connection with the merger, or to the
extent that such termination results from the willful breach by any party of any
representation, warranty or covenant set forth in the merger agreement. There is
no provision in the merger agreement requiring a payment of a termination fee by
any party.

                                       79
<Page>
FEES AND EXPENSES

    The merger agreement provides that all fees and expenses incurred in
connection with the merger agreement, the merger and the other transactions
contemplated by the merger agreement will be paid as described above and
"SPECIAL FACTORS--The Global Transaction--Fees and Expenses." The merger
agreement provides however, that Bacou USA will be responsible for the
reasonable costs and expenses of the oversight committee (including reasonable
costs and expenses of its legal counsel and financial advisors).

AMENDMENT TO THE MERGER AGREEMENT

    The merger agreement may be amended by the parties at any time before or
after the adoption of the merger agreement by the holders of a majority of all
outstanding shares of Bacou USA common stock as of the record date, but after
such adoption of the merger agreement there shall be made no amendment that by
law requires further approval by the stockholders of Bacou USA without the
further approval of such stockholders. The merger agreement may not be amended
except by an instrument in writing signed on behalf of each of the parties.

THE STOCKHOLDER AGREEMENT

    As a condition to the willingness of Christian Dalloz to enter into the
merger agreement, Bacou S.A. has entered into a Company Stockholder Agreement
with Christian Dalloz, dated as of May 29, 2001. As of the date of the
stockholder agreement, Bacou S.A. owned 12,612,600 shares of Bacou USA common
stock, representing as of that date approximately 71.4% of the voting power of
the outstanding shares of Bacou USA common stock. These shares, as well as any
additional shares of capital stock of Bacou USA that Bacou S.A. may acquire
between the date of the stockholder agreement and the effective time of the
merger, are all subject to the stockholder agreement.

    In accordance with the stockholder agreement and subject to certain
exceptions and conditions, Bacou S.A. must, at any meeting of the stockholders
of Bacou USA or in any other circumstances where the vote, consent or other
approval of such stockholders with regard to the merger agreement, the merger or
any other transaction is sought, vote all such shares subject to the stockholder
agreement as follows:

    - in favor of the adoption of the merger agreement;

    - against any other merger agreement or merger, consolidation, combination,
      sale of substantial assets, reorganization, recapitalization, dissolution,
      liquidation or winding up of or by Bacou USA;

    - against any Company Takeover Proposal, as defined in Section 5.02(d) of
      the merger agreement and summarized in "THE MERGER--The Merger
      Agreement--No Solicitation of Other Offers" of this information statement;
      and

    - against any amendment of the Bacou USA Certificate of Incorporation or
      Bacou USA By-laws or any other proposal or transaction involving Bacou USA
      or any of its subsidiaries, which amendment or other proposal or
      transaction would in any manner impede, frustrate, prevent or nullify any
      provision of the merger agreement or the merger, or change in any manner
      the voting rights of any class of Bacou USA common stock.

    Bacou S.A. shall not commit or agree to take any action inconsistent with
the foregoing.

    Furthermore, pursuant to the stockholder agreement Bacou S.A. has appointed
Christian Dalloz, or any individual designated by Christian Dalloz, as Bacou
S.A.'s proxy and attorney-in-fact, with power to vote the shares owned by Bacou
S.A. that are subject to the stockholder agreement in a manner consistent with
the foregoing.

                                       80
<Page>
    Pursuant to the stockholder agreement Bacou S.A. has also covenanted as
follows:

    - that it will not sell, transfer, pledge, assign or otherwise dispose of,
      or enter into any contract, option or other arrangement which would have
      that effect, any shares subject to the stockholder agreement to any
      person, other than pursuant to the merger;

    - that it will not enter into any voting arrangement with respect to any
      shares subject to the stockholder agreement;

    - that it will not, nor will it permit any of its representatives, directly
      or indirectly to solicit, initiate or encourage the submission of any
      Company Takeover Proposal, enter into any agreement with respect to any
      Company Takeover Proposal or directly or indirectly take any actions,
      including discussions, negotiations, facilitations of inquiries, and
      furnishing of information, which may reasonably be expected to lead to any
      Company Takeover Proposal;

    - that it will promptly advise Christian Dalloz orally and in writing of any
      Company Takeover Proposal or inquiry to that effect, the identity of the
      person making such proposal or inquiry, and the material terms of such
      proposal or inquiry;

    - that it will use its best efforts to act, assist and cooperate with all
      parties involved toward the end of consummating and making effective, in
      the most expeditious manner practicable, the merger and the other global
      transactions; and

    - that it will not issue any press release nor make any other public
      statement regarding the merger or any other of the global transactions,
      except as contemplated in the French master agreement or as required by
      applicable law, court process or obligations pursuant to any listing
      agreement with any national securities exchange.

    Pursuant to the stockholder agreement Bacou S.A. has consented to and
approved the actions taken by the board of directors of Bacou USA in approving
the merger and the global transactions. Bacou S.A. has also waived and agreed
not to exercise any appraisal rights available to it under Section 262 of the
General Corporation Law of the State of Delaware in connection with the merger.

    The stockholder agreement terminates, other than with respect to the
liability of any party for breach of such agreement prior to such termination,
upon the earliest of the following:

    - the effective time of the merger;

    - the termination of the merger agreement in accordance with its terms; and

    - December 31, 2001.

CONSIDERATION TO BE RECEIVED BY THE STOCKHOLDERS

    At the effective time of the merger, each share of Bacou USA then issued and
outstanding (other than shares held by any of our subsidiaries, held in our
treasury, held by Christian Dalloz or any subsidiary of Christian Dalloz, held
by Bacou S.A. or any subsidiary of Bacou S.A. and held by stockholders who
perfect their appraisal rights under Delaware law) will be converted into the
right to receive $28.50 in cash without interest, reduced by applicable
withholding tax.

    Each share of common stock of Daniel U. S. Sub then issued and outstanding
will, by virtue of the merger and without any action on the part of Daniel U. S.
Sub, become one fully paid and nonassessable share of common stock of the
surviving corporation.

PROVISIONS FOR UNAFFILIATED STOCKHOLDERS

    Bacou USA has not made any provisions to grant unaffiliated stockholders
access to the corporate files of Bacou USA in connection with the merger. Bacou
USA has not made any provisions to obtain counsel or appraisal services (at its
expense) for any unaffiliated stockholder in connection with the merger.

PROPOSALS BY STOCKHOLDERS

    Due to the contemplated consummation of the merger, Bacou USA does not

proposals of stockholders intended to be presented at the 2001 annual meeting of
stockholders at our principal executive offices no later than the tenth day
following our public announcement of the date of our 2001 annual meeting, for

PRELIMINARY MATERIALS PREPARED BY UBS WARBURG LLC

    At the February 1, 2001 oversight committee meeting, UBS Warburg LLC made a
presentation to the oversight committee. The presentation given by UBS Warburg
LLC consisted of an overview of the auction process based on a review of
information provided by Deutsche Bank and a preliminary valuation analysis of
Bacou USA. The preliminary analysis was not intended to address the fairness,
from a financial point of view, to the public shareholders of Bacou USA of any
proposal to acquire Bacou USA. In connection with the rendering of UBS Warburg
LLC's financial fairness opinion, UBS Warburg LLC's final valuation analysis in
respect of the $28.50 per share final proposal was presented to the oversight
committee on May 25, 2001.

    The February 1, 2001 presentation materials were distributed to the
oversight committee in preliminary form and were based on incomplete
information. These preliminary materials were not prepared with a view toward
public disclosure, and are included in this document only because such
information was made available to the oversight committee. In addition, the
methodologies, assumptions and other factors considered by UBS Warburg LLC in
the preparation of these preliminary materials may not be the same as the
methodologies, assumptions and other factors considered by UBS Warburg LLC in
connection with the other materials prepared by UBS Warburg LLC that are
described in this document.

    In connection with UBS Warburg LLC's review, in September 2000, Bacou USA's
management provided UBS Warburg LLC with a five-year financial forecast that was
prepared by Bacou USA's management in July 2000. Although this forecast was used
in several of the preliminary valuation analyses described in the February 1,
2001 presentation materials, at the time of the February 1, 2001 presentation
and at the time UBS Warburg LLC rendered its financial fairness opinion, Bacou
USA's management had not updated such forecast to reflect Bacou USA's actual
operating performance since July 2000 and the downturn in economic and industry
trends. Accordingly, at the direction of the oversight committee, UBS Warburg
LLC did not take such forecast into consideration in rendering its opinion.

    In connection with its review, at the oversight committee's direction, UBS
Warburg LLC did not assume any responsibility for independent verification of
any of the financial and other information utilized in its preliminary analysis,
and relied on it as being complete and accurate in all material respects. In
addition, at the direction of the oversight committee, UBS Warburg LLC did not
make any independent evaluation or appraisal of any of the assets or
liabilities, contingent or otherwise, of Bacou USA, nor was UBS Warburg LLC
furnished with any such evaluation or appraisal.

    In performing its preliminary analysis, UBS Warburg LLC made numerous
assumptions with respect to industry performance, general business, financial,
market and economic conditions and other matters, many of which are beyond the
control of Bacou USA. No company, transaction or business used in the
preliminary analysis as a comparison is identical to Bacou or its businesses or
the merger, nor is an evaluation of the results entirely mathematical. Rather,
the analyses involve complex considerations and judgments concerning financial
and operating characteristics and other factors that could affect the operating
results, public trading or other values of the companies or transactions being
analyzed.

                                       84

    The estimates contained in the preliminary analyses prepared by UBS Warburg
LLC and the ranges of valuations resulting from any particular analysis are not
necessarily indicative of actual values or predictive of future results or
values, which may be significantly more or less favorable than suggested by
these analyses. In addition, analyses relating to the value of securities do not
purport to be appraisals or to reflect the prices at which a business might
actually be sold or the prices at which any securities may trade at the present
time or at any time in the future.

    The following is a summary of the material preliminary financial analyses
prepared by UBS Warburg LLC and presented to the oversight committee on
February 1, 2001. These preliminary valuation analyses have been included as
Exhibit (c)(6) to the Schedule 13E-3 filed with the Securities and Exchange
Commission in connection with the merger, and the following summary is qualified
by reference to that exhibit. The full text of UBS Warburg LLC's preliminary
presentation is also available for inspection and copying at the corporate
offices of Bacou USA during regular business hours.

    The preliminary financial analyses summarized below include information
presented in tabular format. In order to understand the preliminary analyses
fully, the tables must be read together with the text of each summary.
Considering the data set forth below without considering the full narrative
description of the preliminary analyses, including the methodologies and
assumptions underlying the preliminary analyses, could create a misleading or
incomplete view of the preliminary analyses.

    SELECTED COMPARABLE PUBLIC COMPANY ANALYSIS.  UBS Warburg LLC compared
selected financial information, ratios and public market multiples for Bacou USA
to the corresponding data for the following six publicly-traded companies:

    - Brady Corp.

    - Federal Signal Corp.

    - Mine Safety Appliances Company

    - Scott Technologies, Inc.

    - Sola International Inc.

    - UniFirst Corp.

    UBS Warburg LLC chose the selected companies because they were
publicly-traded companies that, for purposes of the analysis, UBS Warburg LLC
considered reasonably similar to Bacou USA in that these companies operate in
the safety product manufacturing industry. The selected public companies may
significantly differ from Bacou USA based on, among other things, the size of
the companies, the geographic coverage of the companies' operations and the
particular business segments in which the companies focus.

    UBS Warburg LLC reviewed, among other information, the comparable companies'
multiples of TEV to:

    - LTM revenue;

    - LTM EBITDA; and

    - LTM EBIT.

    UBS Warburg LLC also reviewed, among other information, the comparable
companies' P/E multiples for the LTM and projected P/E multiples, based on
I/B/E/S International Inc., or IBES, mean earnings estimates as of January 12,
2002 for the calendar year ending December 31, 2001.

</Table>

    UBS Warburg LLC chose the selected transactions because they were business
combinations that, for the purposes of the analysis, UBS Warburg LLC considered
to be reasonably similar to a business combination involving Bacou USA in that
these transactions involved companies in the safety product manufacturing
industry. The selected transactions may differ significantly from the a business
combination involving Bacou USA based on, among other things, the size of the
transactions, the structure of the transactions and the dates that the
transactions were announced and consummated.

    UBS Warburg LLC reviewed, among other things, the TEVs implied in the
relevant transactions as a multiple of LTM revenue, LTM EBITDA and LTM EBIT and
the EMV implied in the relevant transactions as a multiple of LTM net income and
book value.

    The analysis indicated the following implied multiples for the selected
transactions:

</Table>

    All multiples for the selected transactions were based on publicly available
information at the time of the announcement of the particular transaction. LTM
data for Bacou USA was based on its applicable publicly available annual and
quarterly reports and Bacou USA internal financial reports.

    DISCOUNTED CASH FLOW ANALYSIS.  UBS Warburg LLC performed a discounted cash
flow analysis, using the July 2000 financial forecast prepared by Bacou USA's
management, in order to derive an

                                       86
<Page>
implied equity value reference range for Bacou USA. The discounted cash flow
analysis determined the discounted present value of the unleveraged after-tax
cash flows generated over the five-year period covered by the July 2000
financial forecast and then added a terminal value based upon a range of EBITDA
multiples and perpetuity growth rates based on unleveraged after-tax free cash
flow from 6.0x to 8.0x and 1.8% to 3.0%, respectively. The unleveraged after-tax
cash flows and terminal values were discounted using a range of discount rates
(12.0% to 15.0%) that UBS Warburg deemed appropriate, based on Bacou USA's
weighted average cost of capital. This analysis indicated an implied per share
equity value reference range for Bacou USA of $27.87 to $39.87 using an EBITDA
exit multiple and $21.96 to $33.79 using a perpetuity growth rate.

    LEVERAGED BUYOUT ANALYSIS.  UBS Warburg LLC performed a leveraged buyout
analysis of Bacou USA to show the internal rates of return, or IRRs, to a
typical financial buyer that might be produced assuming the sale of Bacou USA to
such a financial buyer at various per share purchase prices and using the
July 2000 financial forecast prepared by Bacou USA management. A leveraged
buyout involves the acquisition of a company financed primarily by incurring
indebtedness that is serviced by the post-acquisition operating cash flow of the
acquired company. For purposes of the leveraged buyout analysis, UBS Warburg LLC
assumed, among other things: (i) a purchase price per share range of $23.00 to
$29.00; (ii) purchase accounting with no write-up of tangible assets; (iii) a
closing date of December 31, 2000; (iv) a post-closing capital structure
consisting of a fixed dollar amount of bank debt and subordinated debt and an
amount of equity that varies depending on the purchase price per Bacou USA
share, and (iv) that the hypothetical investor sells Bacou at the end of 2005 at
a 7.5x EBITDA multiple, which is consistent with the high end of the comparable
companies' EBITDA trading multiples. The results of these analyses are
summarized in the table below:

PRESENTATION BY DEUTSCHE BANK AT THE FEBRUARY 2, 2001 BACOU USA BOARD MEETING
WITH RESPECT TO THE THEN PROPOSED TRANSACTION WITH A POTENTIAL ACQUIRER

    At the February 2, 2001 meeting of Bacou USA's board of directors, Deutsche
Bank discussed with the board the auction process that had been undertaken to
date with respect to the sale of the Bacou Group and the status of negotiations
with a potential acquirer. Deutsche Bank described the key terms of the offer
from the potential acquirer, reviewed certain financial and comparative
valuation analyses, reviewed the sale process as of that time, provided an
overview of the potential acquirer and reviewed the then prevalent merger and
capital market conditions. As discussed above under "Background of the Merger
and the Related Acquisition Transactions," prior to reaching an agreement on the
principal transaction terms on February 8, 2001 the potential acquirer
terminated negotiations with respect to the potential purchase of the Bacou
Group because the potential acquirer was unable to successfully conclude
discussions with a potential equity financing source.

    Deutsche Bank has not acted as financial advisor to the Oversight Committee.
Deutsche Bank was not requested to, and did not, render an opinion with respect
to the fairness of any of the transactions considered, including the potential
transaction abandoned in February 2001 or the pending merger with Christian
Dalloz, or the consideration to be paid under those transactions, or as to
valuation or otherwise. The materials prepared by Deutsche Bank, including but
not limited to the February 2, 2001 information materials, are not an opinion as
to the fairness to Bacou USA or its shareholders of any of the transactions
considered or the consideration to be paid under those transactions, do not
constitute a recommendation to Bacou USA or its shareholders as to any of the
transactions considered or as to any action they should take or not take with
respect to the transaction with Christian Dalloz, and should not be relied on as
a basis for any investment decision.

    Copies of the February 2, 2001 information materials are available for
inspection and copying at Bacou USA's principal executive offices at 10 Thurber
Boulevard, Smithfield, Rhode Island 02917, during regular business hours by any
interested shareholder of Bacou USA or the shareholder's representative who has
been so designated in writing. We have also filed these materials with the
Securities and Exchange Commission as exhibits to the Schedule 13E-3.

    In connection with its presentation made on February 2, 2001 and its role as
financial advisor to the Bacou family and Bacou USA, Deutsche Bank has, among
other things:

    - reviewed certain publicly available financial information and other
      information concerning Bacou USA;

    - reviewed certain internal analyses and other information furnished to
      Deutsche Bank by the Bacou Group and Bacou USA;

    - held discussions with members of the senior management of the Bacou Group
      and Bacou USA regarding the businesses and prospects of Bacou USA;

    - reviewed the reported prices and trading activity for the shares;

    - reviewed the financial terms of the transaction that was proposed between
      the potential acquirer and the Bacou Group and reviewed on February 2,
      2001; and

    - performed such other studies and analyses and considered such other
      factors as Deutsche Bank deemed appropriate.

    Deutsche Bank did not assume responsibility for the independent verification
of, and did not independently verify, any information concerning the Bacou
Group, Bacou USA or the potential acquirer, whether publicly available or
furnished to Deutsche Bank, including, without limitation, any financial
information, forecasts or projections, considered in connection with the
preparation and presentation of the information materials. Accordingly, Deutsche
Bank assumed and relied upon the accuracy and completeness of all such
information. Deutsche Bank, in its role as financial advisor to the Bacou family
and Bacou USA, did not conduct a physical inspection of any of the properties or
assets, and did not prepare or obtain any independent evaluation or appraisal of
any of the assets or liabilities of Bacou USA. The February 2, 2001 information
materials prepared and presented by Deutsche Bank were necessarily based upon
economic, market and other conditions as in effect on, and the information made
available to Deutsche Bank as of, February 2, 2001.

    The following is a summary of the Deutsche Bank February 2, 2001 information
materials and does not purport to be a complete description of the analyses
performed by Deutsche Bank. The following quantitative information, to the
extent it is based on market data, is based on market data as it existed at or
about February 2, 2001, and is not necessarily indicative of current market
conditions. In addition, the following quantitative information was prepared in
the context of a different transaction and is not necessarily relevant or
applicable to the merger and related acquisition transactions with Christian
Dalloz. You should understand that the order of analyses and the results derived
from these analyses described below do not represent relative importance or
weight given to these analyses by Deutsche Bank. The summary of the February 2,
2001 information materials described below is qualified in its entirety to the
full text of the materials.

    EXECUTIVE SUMMARY.  The February 2, 2001 presentation contained a brief
summary of the presentation that (1) identified the potential acquirer, and the
contemplated timing for the signing of agreements and closing the proposed
transaction with the potential acquirer, (2) identified certain determinants of
the valuation for the Bacou Group, and (3) included a one page chart of the
historical price and volume performance of Bacou USA's common stock for the
period beginning with Bacou USA's initial public offering through January 31,
2001. The chart highlighted the timing of certain publicly disclosed events in
Bacou USA's history during such period.

    OVERVIEW OF THE POTENTIAL ACQUIRER'S PROPOSED TRANSACTION FOR THE BACOU

    The February 2, 2001 presentation also included in a graphic format an
analysis of the performance of the Bacou USA common stock relative to the
Standard & Poor's industrial stock index, the Russel 2000 stock index, and an
index of selected comparable industrial companies (the companies listed in the
"Selected Comparable Public Company Analysis" below) over the twelve month
period ending January 31, 2001, as well as for the time period beginning from
the initial public offering of

                                       90
<Page>
Bacou USA through January 31, 2001. The analysis revealed that the Bacou USA
common stock had outperformed the other benchmark indices over the twelve month
period ended January 31, 2001. The analysis also revealed that the Bacou USA
common stock had outperformed the other benchmark indices over the time period
beginning from the initial public offering of Bacou USA through January 31, 2001
other than the Standard & Poor's industrial stock index.

    SELECTED COMPARABLE PUBLIC COMPANY ANALYSIS.  Deutsche Bank compared
selected financial information, ratios and public market multiples for Bacou USA
to the corresponding data for the following six publicly traded companies:

    - Robbins & Myers, Inc.

    - Kaydon Corporation

    - IDEX Corporation

    - Mine Safety Appliances Company

    - Regal-Beloit Corporation

    - Checkpoint Systems, Inc.

    Deutsche Bank chose the selected companies because they were publicly traded
companies that, for the purposes of the analysis, Deutsche Bank considered
reasonably similar to Bacou USA in that these companies produce general
industrial products that are used in a broad array of end markets. The selected
public companies may significantly differ from Bacou USA based on, among other
things, the particular industrial product markets in which the companies focus,
the size of the companies and the geographic coverage of the companies'
operations.

    Deutsche Bank reviewed, among other information, the selected companies'
multiples of total enterprise value, referred to as TEV, to:

    - revenue for the latest twelve months ended September 30, 2000, referred to
      as LTM, as well as estimated revenue for the years ending December 31,
      2000 and December 31, 2001.

    - adjusted earnings before interest, taxes, depreciation and amortization,
      referred to as EBITDA, for the LTM period, as well as estimated EBITDA for
      the years ending December 31, 2000 and December 31, 2001.

    - adjusted earnings before interest and taxes, referred to as EBIT, for the
      LTM period, as well as estimated EBIT for the years ending December 31,
      2000 and December 31, 2001.

    TEV consists of the particular company's equity value, plus the value of the
particular company's total debt and preferred stock, minus cash, cash
equivalents and marketable securities.

    Deutsche Bank also reviewed, among other information, the selected
companies' price /estimated earnings multiples, referred to as P/E, based on the
then median First Call consensus earnings estimates for the years ending
December 31, 2000 and December 31, 2001.

    LTM data for Bacou USA and the selected companies were based on the
respective companies' publicly available annual and quarterly reports. Estimated
2000 and 2001 data for Bacou USA, which were reviewed on a proforma adjusted
basis, were based on the financial projections prepared by Bacou USA management
and contained in the confidential information memorandum distributed in August
2000. Estimated 2000 and 2001 data for the comparable companies were obtained
from then available Wall Street equity research reports.

                                       91

    The Bacou USA selected companies analysis resulted in the following ranges

    Deutsche Bank chose the selected transactions because they were business
combinations that, for the purposes of the analysis, Deutsche Bank considered to
be reasonably similar to the proposed transaction in that these transactions
involved companies that manufactured general industrial products used in a broad
array of end markets. The selected transactions may differ significantly from
the proposed transaction based on, among other things, the particular industrial
product markets in which the companies focus, the size of the transactions, the
structure of the transactions and the dates the transactions were announced and
consummated.

    Deutsche Bank reviewed among other things, the TEVs implied in the relevant
transactions as a multiple of LTM revenue, LTM adjusted EBITDA and LTM adjusted
EBIT. The analysis indicated the following implied multiples for the selected
transactions and for the proposed transaction.

relevant proposed draft transaction agreements.

    REVIEW OF THE SALE PROCESS.  The February 2, 2001 presentation summarized
the key events in the sale process conducted to that date by Deutsche Bank
following its engagement as financial advisor to Bacou USA and the Bacou family,

of interest and those participating in management presentations and detailed
diligence reviews. The review of the sale process also summarized in one page
the discussions with the two parties that had submitted revised proposals.

    OVERVIEW OF POTENTIAL ACQUIRER AND POTENTIAL SOURCE OF EQUITY
FINANCING.  The February 2, 2001 presentation provided a summary overview of the
potential acquirer including key historical milestones, a breakdown of the
potential acquirer's sales by product, and the potential acquirer's plans for
the combined company. Because the potential acquirer required third party equity
financing as part of the overall financing for the proposed transaction, the
February 2, 2001 presentation also provided a summary overview of a potential
equity financing source, including the potential equity sponsor's history,
selected other investments and a brief overview of selected key principals of
the firm.

    REVIEW OF MERGER AND CAPITAL MARKET CONDITIONS.  The February 2, 2001

    APPENDICES.  The February 2, 2001 presentation provided in summary form the
market statistics, consensus estimates and public market valuation for selected
comparable industrial companies, as well as summary descriptions of and
valuations of selected comparable industrial transactions.

    The foregoing summary describes the material analyses and factors that
Deutsche Bank presented at the February 2, 2001 meeting of the Board of
Directors, but it is not a complete description of all analyses performed and
factors considered by Deutsche Bank in connection with that presentation.

other appropriate documents (in any such case, the "Certificate of Merger")

effective at such time as the Certificate of Merger is duly filed with such
Secretary of State, or at such later time as Parent and the Company shall agree
and specify in the Certificate of Merger (the time the Merger becomes effective
being the "Effective Time").

    SECTION 1.04.  EFFECTS.  The Merger shall have the effects set forth in this
Agreement and Section 259 of the DGCL.

    SECTION 1.05.  CERTIFICATE OF INCORPORATION AND BY-LAWS.  (a) The

Time to read in the form of Exhibit A, and, as so amended, such Certificate of
Incorporation shall be the Certificate of Incorporation of the Surviving
Corporation until thereafter changed or amended as provided therein or by
applicable law.

        (b) The By-laws of Sub as in effect immediately prior to the Effective
    Time shall be the By-laws of the Surviving Corporation until thereafter
    changed or amended as provided therein or by applicable law.

    SECTION 1.06.  DIRECTORS.  The directors of Sub immediately prior to the
Effective Time shall be the directors of the Surviving Corporation, until the
earlier of their resignation or removal or until their respective successors are
duly elected and qualified, as the case may be.

    SECTION 1.07.  OFFICERS.  The officers of the Company immediately prior to
the Effective Time shall be the officers of the Surviving Corporation, until the
earlier of their resignation or removal or until their respective successors are

                                   ARTICLE II
                       EFFECT ON THE CAPITAL STOCK OF THE
               CONSTITUENT CORPORATIONS; EXCHANGE OF CERTIFICATES

    SECTION 2.01.  EFFECT ON CAPITAL STOCK.  At the Effective Time, by virtue of
the Merger and without any action on the part of the holder of any shares of
Company Common Stock or any shares of capital stock of Sub:

        (a)  CAPITAL STOCK OF SUB.  Each issued and outstanding share of capital
    stock of Sub shall be converted into and become one fully paid and
    nonassessable share of common stock of the Surviving Corporation.

                                      A-2
<Page>
        (b)  CANCELATION OF CERTAIN STOCK.  Each share of Company Common Stock
    that is owned by the Company, Parent or Sub shall no longer be outstanding
    and shall automatically be canceled and shall cease to exist and no
    consideration shall be delivered or deliverable in exchange therefor. Each
    share of Company Common Stock that is owned by any subsidiary of the Company
    or Parent (other than Sub) shall automatically be converted into one fully
    paid and nonassessable share of common stock of the Surviving Corporation.
    Each share of the Company Common Stock that is owned by the Principal
    Company Stockholder shall remain outstanding as a share of common stock of
    the Surviving Corporation.

        (c)  CONVERSION OF COMPANY COMMON STOCK.  (i) Except as otherwise
    provided in Sections 2.01(b) and 2.01(d), each issued share of Company
    Common Stock shall be converted into the right to receive $28.50 in cash.

           (ii) The cash payable upon the conversion of shares of Company Common
       Stock pursuant to this Section 2.01(c) is referred to collectively as the
       "Merger Consideration". As of the Effective Time, all such shares of
       Company Common Stock shall no longer be outstanding and shall
       automatically be canceled and shall cease to exist, and each holder of a
       certificate representing any such shares of Company Common Stock shall
       cease to have any rights with respect thereto, except the right to
       receive Merger Consideration upon surrender of such certificate in
       accordance with Section 2.02, without interest.

        (d)  APPRAISAL RIGHTS.  Notwithstanding anything in this Agreement to
    the contrary, but only to the extent required by DGCL, shares of Company
    Common Stock that are outstanding immediately prior to the Effective Time
    and that are held by any person who is entitled to demand and properly
    demands appraisal of such shares ("Appraisal Shares") in connection with the
    Merger pursuant to, and who complies in all respects with, Section 262 of
    the DGCL ("Section 262") shall not be converted into the right to receive
    the Merger Consideration as provided in Section 2.01(c), but rather the
    holders of Appraisal Shares shall be entitled to such consideration as may
    be determined to be due to such dissenting stockholders pursuant to
    Section 262; provided, however, that if any such holder shall fail to
    perfect or otherwise shall waive, withdraw or lose the right to appraisal
    under Section 262, then the right of such holder to be paid the fair value
    of such holder's Appraisal Shares shall cease and such Appraisal Shares
    shall be deemed to have been converted as of the Effective Time into, and to
    have become exchangeable solely for the right to receive, the Merger
    Consideration as provided in Section 2.01(c). The Company shall serve prompt
    notice to Parent of any demands received by the Company for appraisal of any
    shares of Company Common Stock, and Parent shall have the right to
    participate in and direct all negotiations and proceedings with respect to
    such demands. Prior to the Effective Time, the Company shall not, without
    the prior written consent of Parent, make any payment with respect to, or
    settle or offer to settle, any such demands, or agree to do any of the
    foregoing.

    SECTION 2.02.  EXCHANGE OF CERTIFICATES.  (a) PAYING AGENT. Prior to the
Effective Time, Parent shall select a bank or trust company, reasonably
acceptable to the Company, to act as paying agent (the "Paying Agent") for the
payment of the Merger Consideration upon surrender of certificates representing
Company Common Stock converted pursuant to Section 2.01(c). Immediately after
the Effective Time, Parent shall provide to the Paying Agent cash necessary to
pay for the shares of Company Common Stock converted into the right to receive
cash pursuant to Section 2.01(c) (such cash being hereinafter referred to as the
"Exchange Fund").

        (b)  EXCHANGE PROCEDURE.  As soon as reasonably practicable after the
    Effective Time, the Paying Agent shall mail to each holder of record of a
    certificate or certificates (the "Certificates") that immediately prior to
    the Effective Time represented outstanding shares of Company Common Stock
    whose shares were converted into the right to receive Merger Consideration
    pursuant to Section 2.01, (i) a letter of transmittal (which shall specify
    that delivery shall be effected, and risk

                                      A-3
<Page>
    of loss and title to the Certificates shall pass, only upon delivery of the
    Certificates to the Paying Agent and shall be in such form and have such
    other provisions as Parent may reasonably specify) and (ii) instructions for
    use in effecting the surrender of the Certificates in exchange for Merger
    Consideration. Upon surrender of a Certificate for cancelation to the Paying
    Agent or to such other agent or agents as may be appointed by Parent,
    together with such letter of transmittal, duly executed, and such other
    documents as may reasonably be required by the Paying Agent, the holder of
    such Certificate shall be entitled to receive in exchange therefor the
    amount of cash payable pursuant to Section 2.01, and the Certificate so
    surrendered shall forthwith be canceled. In the event of a transfer of
    ownership of Company Common Stock that is not registered in the transfer
    records of the Company, payment may be made to a person other than the
    person in whose name the Certificate so surrendered is registered, if such
    Certificate shall be properly endorsed or otherwise be in proper form for
    transfer and the person requesting such payment shall pay any transfer or
    other taxes required by reason of the payment to a person other than the
    registered holder of such Certificate or establish to the satisfaction of
    Parent that such tax has been paid or is not applicable. Until surrendered
    as contemplated by this Section 2.02, each Certificate shall be deemed at
    any time after the Effective Time to represent only the right to receive
    upon such surrender the amount of cash, without interest, payable pursuant
    to Section 2.01. No interest shall be paid or accrue on the cash payable
    upon surrender of any Certificate.

        (c)  NO FURTHER OWNERSHIP RIGHTS IN COMPANY COMMON STOCK.  The Merger
    Consideration paid in accordance with the terms of this Article II upon
    conversion of any shares of Company Common Stock shall be deemed to have
    been paid in full satisfaction of all rights pertaining to such shares of
    Company Common Stock, subject, however, to the Surviving Corporation's
    obligation to pay any dividends or make any other distributions with a
    record date prior to the Effective Time that may have been declared or made
    by the Company on such shares of Company Common Stock in accordance with the
    terms of this Agreement or prior to the date of this Agreement and which
    remain unpaid at the Effective Time, and after the Effective Time there
    shall be no further registration of transfers on the stock transfer books of
    the Surviving Corporation of shares of Company Common Stock that were
    outstanding immediately prior to the Effective Time and converted into the
    right to receive the Merger Consideration pursuant to Section 2.01(c). If,
    after the Effective Time, any certificates formerly representing shares of
    Company Common Stock are presented to the Surviving Corporation or the
    Paying Agent for any reason, they shall be canceled and exchanged or
    otherwise treated as provided in this Article II.

        (d)  TERMINATION OF EXCHANGE FUND.  Any portion of the Exchange Fund
    that remains undistributed to the holders of Company Common Stock for nine
    months after the Effective Time shall be delivered to Parent, upon demand,
    and any holder of Company Common Stock who has not theretofore complied with
    this Article II shall thereafter look only to Parent for payment of its
    claim for Merger Consideration.

        (e)  NO LIABILITY.  None of Parent, Sub, the Company or the Paying Agent
    shall be liable to any person in respect of any cash from the Exchange Fund
    delivered to a public official pursuant to any applicable abandoned
    property, escheat or similar applicable law.

        (f)  INVESTMENT OF EXCHANGE FUND.  The Paying Agent shall invest any
    cash included in the Exchange Fund, as directed by Parent, on a daily basis
    in direct obligations of the United States, obligations for which the full
    faith and credit of the United States is pledged to provide for the payment
    of principal and interest, commercial paper rated of the highest quality by
    Moody's Investors Services, Inc. or Standard & Poor's Ratings Group or
    certificates of deposit, bank repurchase agreements or bankers' acceptances
    of a commercial bank having at least $1,000,000,000 in assets (collectively,
    "Permitted Investments") or in money market funds which

                                      A-4
<Page>
    are invested in Permitted Investments. Any interest and other income
    resulting from such investments shall be paid to Parent.

        (g)  WITHHOLDING RIGHTS.  Parent, the Surviving Corporation or the
    Exchange Agent shall be entitled to deduct and withhold from the
    consideration otherwise payable to any holder of Company Common Stock
    pursuant to this Agreement such amounts as may be required to be deducted
    and withheld with respect to the making of such payment under the Internal
    Revenue Code of 1986, as amended (the "Code"), or under any provision of
    state, local or foreign tax law.

        (h)  LOST, STOLEN OR DESTROYED CERTIFICATES.  In the event any
    Certificate shall have been lost, stolen or destroyed, upon the making of an
    affidavit of that fact by the person claiming such Certificate to be lost,
    stolen or destroyed, the Paying Agent shall issue in exchange for such lost,
    stolen or destroyed Certificate the Merger Consideration deliverable in
    respect thereof as determined in accordance with this Article II; provided,
    however, that the person to whom the Merger Consideration is paid shall, as

                                  ARTICLE III
                 REPRESENTATIONS AND WARRANTIES OF THE COMPANY

    The Company represents and warrants to Parent and Sub that, except as set
forth in the Schedules to this Agreement and as disclosed in Company SEC
Documents:

    SECTION 3.01.  ORGANIZATION, STANDING AND POWER.  Each of the Company and
each of its subsidiaries (the "Company Subsidiaries") is duly organized, validly
existing and in good standing under the laws of the jurisdiction in which it is
organized and has full corporate or other power and authority and possesses all
governmental franchises, licenses, permits, authorizations and approvals
necessary to enable it to own, lease or otherwise hold its properties and assets
and to conduct its businesses as presently conducted, other than such
franchises, licenses, permits, authorizations and approvals the lack of which,
individually or in the aggregate, has not had and would not reasonably be
expected to have a material adverse effect on the ability of the Company to
perform its obligations under this Agreement, a material adverse effect on the
ability of the Company to consummate the Merger and the other transactions
contemplated hereby or a material adverse effect on the business, financial
condition or results of operations of the Company and the Company Subsidiaries,
taken as a whole, other than any such effect arising out of or resulting from
(i) changes in general economic conditions, (ii) general changes or developments
in the industries in which the Company and the Company Subsidiaries operate and
(iii) facts or events that are primarily and directly attributable to the
announcement of this Agreement and the transactions contemplated hereby (a
"Company Material Adverse Effect"). The Company has made available to Parent
true and complete copies of the certificate of incorporation of the Company, as
amended to the date of this Agreement (as so amended, the "Company Charter"),
and the By-laws of the Company, as amended to the date of this Agreement (as so
amended, the "Company By-laws"), and the comparable charter and organizational
documents of each Company Subsidiary, in each case as amended through the date
of this Agreement.

    SECTION 3.02.  AUTHORITY; EXECUTION AND DELIVERY; ENFORCEABILITY.  (a) The
Company has all requisite corporate power and authority to execute and deliver
this Agreement, to perform its obligations hereunder and, subject to obtaining
the Company Stockholder Approval, to consummate the transactions contemplated
hereby. The execution and delivery by the Company of this Agreement and the
consummation by the Company of the transactions contemplated hereby have been
duly authorized by all necessary corporate action on the part of the Company,
subject, in the case of the Merger, to

                                      A-5
<Page>
receipt of the Company Stockholder Approval (as defined in Section 6.01(b)).
Except for the Company Stockholder Approval, no other corporate action on the
part of the Company is necessary to authorize the execution, delivery and
performance of this Agreement and the consummation by it of the transactions
contemplated hereby. The Company has duly executed and delivered this Agreement,
and, assuming its due execution and delivery by the other parties hereto, this
Agreement constitutes its legal, valid and binding obligation, enforceable
against it in accordance with its terms, except to the extent that its
enforceability may be subject to applicable bankruptcy, insolvency,
reorganization, moratorium and similar laws affecting the enforcement of
creditors' rights generally and by general equitable principles.

        (b) The Oversight Committee has (i) approved this Agreement and the
    Merger, (ii) recommended the adoption of this Agreement and the Merger by
    the Company Board and (iii) determined that this Agreement and the Merger
    are advisable and in the best interests of the Company and each of the
    holders of the Company Common Stock other than the Principal Company
    Stockholder. The Company Board, after a unanimous recommendation of the
    Oversight Committee, at a meeting duly called and held, has (i) determined
    that this Agreement and the Merger are advisable and in the best interests
    of the Company and each of the holders of the Company Common Stock other
    than the Principal Company Stockholder, (ii) approved this Agreement and the
    Merger in accordance with the requirements of the DGCL, (iii) resolved to
    recommend the adoption of this Agreement and the Merger by its stockholders
    other than the Principal Company Stockholder and (iv) adopted resolutions
    and taken all necessary actions to terminate the Letter Agreement dated
    July 13, 2000, among Jacqueline Maggi Bacou, Christophe Bacou, Philippe
    Bacou, Veronique Mirabel and the Company. UBS Warburg LLC has delivered to
    the Oversight Committee its opinion that the consideration to be paid in the
    Merger to each of the holders of the Company Common Stock other than the
    Principal Company Stockholder is fair to such holder from a financial point
    of view ("UBS Warburg LLC Fairness Opinion").

    SECTION 3.03.  CONSENTS.  No consent, approval, license, permit, order or
authorization of, or registration, declaration or filing with, or permit from,
any Federal, state, local or foreign government or any court of competent
jurisdiction, administrative agency or commission or other governmental
authority or instrumentality, domestic or foreign (a "Governmental Entity") is
required to be obtained or made by or with respect to the Company or any Company
Subsidiary in connection with the execution, delivery and performance of this
Agreement or the consummation of the transactions contemplated hereby, other

applicable state takeover law and (vi) such other items (A) that may be required
under the applicable law of any foreign country, (B) required solely by reason
of the participation of Parent (as opposed to any third party) in the
transactions contemplated hereby or (C) that, individually or in the aggregate,
have not had and would not reasonably be expected to have a Company Material
Adverse Effect.

    SECTION 3.04.  SEC DOCUMENTS.  The Company has filed all reports, schedules,
forms, statements and other documents required to be filed by the Company with
the Securities and Exchange Commission (the "SEC") since December 31, 1997 (the

<Page>
respective date, each Company SEC Document complied in all material respects
with the requirements of the Exchange Act, or the Securities Act of 1933, as
amended (the "Securities Act"), as the case may be, and the rules and
regulations of the SEC promulgated thereunder applicable to such Company SEC
Document, and did not contain any untrue statement of a material fact or omit to

circumstances under which they were made, not misleading.

    SECTION 5.02.  NO SOLICITATION.  (a) Except as provided below, the Company
shall not, nor shall it authorize or permit any Company Subsidiary to, nor shall
it authorize or permit any officer, director or employee of, or any investment
banker, attorney or other advisor or representative (collectively,
"Representatives") of, the Company or any Company Subsidiary to, during the
period from the date of this Agreement to the Effective Time, (i) directly or
indirectly solicit, initiate or encourage the submission of, any Company
Takeover Proposal (as defined in Section 5.02(d)), (ii) enter into any agreement
with respect to any Company Takeover Proposal or (iii) directly or indirectly
participate in any discussions or negotiations regarding, or furnish to any
person any information with respect to, or take any other action to facilitate
any inquiries or the making of any proposal that constitutes, or may reasonably
be expected to lead to, any Company Takeover Proposal. Notwithstanding the
foregoing, if the Company, the Company Board or the Oversight Committee, without
being in violation of the terms of this Section 5.02(a), receives an unsolicited
bona fide proposal from any Person or group with respect to a Company Takeover
Proposal which could reasonably be expected to result in a Superior Proposal,
then the Company may, directly or indirectly, furnish information and access to
such Person or group pursuant to an appropriate confidentiality agreement, and
may participate in discussions and negotiations with such Person or group.

        (b) Except as provided below, neither the Company Board nor any

    (i) withdraw or modify in a manner adverse to Parent or Sub, or propose to
    withdraw or modify, in a manner adverse to Parent or Sub, the approval or
    recommendation by the Company Board or any such committee of this Agreement

    acquisition agreement or similar agreement relating to any Company Takeover
    Proposal or (iii) approve or recommend, or propose to approve or recommend,

    receipt of the Company Stockholder Approval, the Company Board receives a
    Superior Proposal and as a result thereof the Oversight Committee determines
    in good faith, after receipt of advice of its outside legal counsel, that
    failure to take such action would constitute a breach of the Company Board's
    fiduciary duties to the Company's stockholders under applicable law, the
    Oversight Committee (and the Company Board acting on the recommendation of
    the Oversight Committee) may withdraw or modify its approval or
    recommendation of this Agreement and the Merger and disclose such withdrawal
    or modification to the Company's stockholders.

        (c) The Company shall promptly advise Parent of any Company Takeover
    Proposal or any inquiry with respect to or that could reasonably be expected
    to lead to any Company Takeover

                                      A-11
<Page>
    Proposal, occurring during the period from the date of this Agreement to the
    earlier of the termination of this Agreement and the Effective Time, and the
    identity of the person making any such Company Takeover Proposal or inquiry,
    including any change to the material terms of any such Company Takeover
    Proposal or inquiry. The Company shall (i) keep Parent fully informed of the
    status (including any change to the details) of any such Company Takeover
    Proposal or inquiry and (ii) provide to Parent as soon as practicable after
    receipt or delivery thereof with copies of all correspondence and other
    written material sent or provided to the Company from any third party in
    connection with any Company Takeover Proposal or sent or provided by the
    Company to any third party in connection with any Company Takeover Proposal.

        (d) For purposes of this Agreement, "Company Takeover Proposal" means
    (i) any proposal or offer for a merger, consolidation, dissolution,
    recapitalization or other business combination involving the Company,
    (ii) any proposal for the issuance by the Company of over 15% of its equity
    securities as consideration for the assets or securities of another person
    or (iii) any proposal or offer to acquire in any manner, directly or
    indirectly, over 15% of the equity securities or consolidated total assets
    of the Company, in each case other than the transactions contemplated by
    this Agreement and other than any acquisition transaction permitted by
    Section 5.01. For the purposes of this Agreement, "Superior Proposal" means
    any bona fide proposal to acquire, directly or indirectly, for consideration
    consisting of cash, all of the shares of Company Common Stock then
    outstanding or all or substantially all of the assets of the Company to be
    followed by a pro rata distribution of the sale proceeds to the stockholders
    of the Company, that (i) provides holders of the Company Common Stock with
    per share consideration that the Oversight Committee determines in good
    faith, after receipt of advice of its financial advisor, is more favorable
    from a financial point of view than the consideration to be received by
    holders of Company Common Stock in the Merger, (ii) is determined by the
    Oversight Committee in its good faith judgment, after receipt of advice of
    its financial advisor and outside legal counsel, to be likely of being
    completed (taking into account all legal, financial, regulatory and other
    aspects of the proposal, the person making the proposal and the expected
    timing to complete the proposal), (iii) does not, in the definitive
    acquisition agreement, contain any "due diligence" conditions, and (iv) has
    not been obtained by or on behalf of the Company in violation of this
    Section 5.02.

        (e) Notwithstanding any provision of this Agreement to the contrary, the
    Company Board shall be permitted, to the extent applicable, to comply with
    Rule 14d-9 and Rule 14e-2(a) promulgated under the Exchange Act with regard
    to any Company Takeover Proposal, or make any other disclosure required by
    applicable law, so long as any such disclosure rejects any Company Takeover
    Proposal and reaffirms the Company Board's recommendation of the
    transactions contemplated by this Agreement, subject to Section 5.02(b)
    hereof. For avoidance of doubt, none of the Company, the Company Board or
    the Oversight Committee may terminate this Agreement as a result of the
    existence of a Superior Proposal.

                                   ARTICLE VI
                             ADDITIONAL AGREEMENTS

    SECTION 6.01.  PREPARATION OF SEC STATEMENT; STOCKHOLDERS MEETING.  (a) As
promptly as practicable following the date of this Agreement, the Company and
Parent shall prepare and file with the SEC an information statement on
Schedule 14C and an information statement on Schedule 13E-3 (collectively
referred to herein as the "Information Statement") in preliminary form, and each
of the Company and Parent shall use its reasonable efforts to respond as
promptly as practicable to any comments of the SEC with respect thereto. The
Company shall notify Parent promptly of the receipt of any comments from the SEC
or its staff and of any request by the SEC or its staff for amendments or
supplements to the SEC Statement or for additional information and shall supply
Parent with copies of

                                      A-12
<Page>
all correspondence between the Company or any of its representatives, on the one
hand, and the SEC or its staff, on the other hand, with respect to the SEC
Statement. The Company shall not mail any SEC Statement, or any amendment or
supplement thereto, to which Parent reasonably objects.

        (b) In the event that the Company and Parent are informed by the SEC
    that the SEC plans to review the Information Statement, the Company and
    Parent may, in Parent's sole discretion, elect to file the SEC Statement as
    a proxy statement instead of an Information Statement and, as soon as
    practicable thereafter, the Company shall duly call, give notice of, convene
    and hold a meeting of its stockholders (the "Company Stockholders Meeting")
    for the purpose of seeking the adoption of this Agreement by such
    stockholders (such adoption, whether obtained at the Company Stockholders
    Meeting or by written consent in lieu of the Company Stockholders Meeting,
    the "Company Stockholder Approval"). Except as permitted by
    Section 5.02(b), the proxy statement shall include (i) the recommendation of
    the Oversight Committee to the Company stockholders in favor of the Company
    Stockholder Approval and (ii) the recommendation of the Company Board to the
    Company stockholders in favor of the Company Stockholder Approval. Without
    limiting the generality of the foregoing, the Company agrees that its
    obligations pursuant to the first sentence of this Section 6.01(b) shall not
    be affected by the commencement, public proposal, public disclosure or
    communication to the Company of any Company Takeover Proposal.

    SECTION 6.02.  ACCESS TO INFORMATION; CONFIDENTIALITY.  The Company shall,
and shall cause each Company Subsidiary to, afford to Parent, and to Parent's
officers, employees, accountants, counsel, financial advisors and other
representatives, reasonable access during normal business hours during the
period prior to the Effective Time to all their respective properties, books,
contracts, commitments, personnel and records and, during such period, the
Company shall, and shall cause each Company Subsidiary to, furnish promptly to
Parent (a) a copy of each report, schedule, registration statement and other
document filed by it during such period pursuant to the requirements of Federal
or state securities laws and (b) all other information concerning its business,
properties and personnel as Parent may reasonably request. All information
exchanged pursuant to this Section 6.02 shall be subject to the confidentiality
agreement dated August 11, 2000, between the Company and Parent (the
"Confidentiality Agreement").

    SECTION 6.03.  REASONABLE BEST EFFORTS; NOTIFICATION.  (a) Upon the terms
and subject to the conditions set forth in this Agreement, each of the parties
shall use its reasonable best efforts to take, or cause to be taken, all
actions, and to do, or cause to be done, and to assist and cooperate with the
other parties in doing, all things necessary, proper or advisable to consummate
and make effective, in the most expeditious manner practicable, the Merger and
the other transactions contemplated hereby, including (i) the obtaining of all
necessary actions or nonactions, waivers, consents and approvals from
Governmental Entities and the making of all necessary registrations and filings
(including filings with Governmental Entities, if any) and the taking of all
reasonable steps as may be necessary to obtain an approval or waiver from, or to
avoid an action or proceeding by, any Governmental Entity, (ii) the obtaining of
all necessary consents, approvals or waivers from third parties, (iii) the
defending of any lawsuits or other legal proceedings, whether judicial or
administrative, challenging this Agreement or the consummation of the
transactions contemplated hereby, including seeking to have any stay or
temporary restraining order entered by any court or other Governmental Entity
vacated or reversed and (iv) the execution and delivery of any additional
instruments necessary to consummate the transactions contemplated hereby and to
fully carry out the purposes of this Agreement. In connection with and without
limiting the foregoing, the Company and the Company Board shall (i) take all
action necessary to ensure that no state takeover statute or similar statute or
regulation is or becomes applicable to this Agreement or any transaction
contemplated hereby and (ii) if any state takeover statute or similar statute or
regulation becomes applicable to this Agreement, take all action necessary to
ensure that the Merger and the other transactions contemplated hereby may be
consummated as promptly as practicable on the terms contemplated by this
Agreement and otherwise to minimize the

                                      A-13
<Page>
effect of such statute or regulation on the Merger and the other transactions
contemplated hereby. Nothing in this Agreement shall be deemed to require any
party to waive any substantial rights or agree to any substantial limitation on
its operations or to dispose of any significant asset or collection of assets.

        (b) The Company shall give prompt notice to Parent, and Parent or Sub
    shall give prompt notice to the Company, of (i) any representation or
    warranty made by it contained in this Agreement that is qualified as to
    materiality becoming untrue or inaccurate in any respect or any such
    representation or warranty that is not so qualified becoming untrue or
    inaccurate in any material respect or (ii) the failure by it to comply with
    or satisfy in any material respect any covenant, condition or agreement to
    be complied with or satisfied by it under this Agreement; provided, however,
    that no such notification shall affect the representations, warranties,
    covenants, conditions or agreements of the parties or the conditions to the
    obligations of the parties under this Agreement.

    SECTION 6.04.  STOCK OPTIONS.  (a) As soon as practicable following the date
of this Agreement, the Company Board (or, if appropriate, any committee
administering the Company Stock Plans) shall adopt such resolutions or take such
other actions as are required to adjust the terms of all Company Employee Stock
Options to provide that each Company Employee Stock Option outstanding at the
Effective Time shall become fully exercisable and vested and shall not give the
holder thereof the right to receive any capital stock of the Company or the
Surviving Corporation after the Effective Time or to receive from the Company or
the Surviving Corporation any consideration other than, in the case of the
exercise of any Company Employee Stock Option, cash equal to the product of
(i) the number of shares of Company Common Stock subject to such Company
Employee Stock Option immediately prior to the Effective Time and (ii) the
excess, if any, of the Merger Consideration over the per share exercise price of
such Company Employee Stock Option.

        (b) All amounts payable pursuant to this Section 6.04 shall be subject
    to any required withholding of taxes and shall be paid without interest. The
    Company shall use its reasonable best efforts to obtain all consents of the
    holders of the Company Employee Stock Options as shall be necessary to
    effectuate the foregoing. Notwithstanding anything to the contrary contained
    in this Agreement, payment shall, at Parent's request, be withheld in
    respect of any Company Employee Stock Option until all necessary consents
    are obtained.

        (c)The Company Stock Plans shall terminate as of the Effective Time, and
    the provisions in any other benefit plan providing for the issuance,
    transfer or grant of any capital stock of the Company or any interest in
    respect of any capital stock of the Company shall be deleted as of the
    Effective Time, and the Company shall ensure that following the Effective
    Time no holder of a Company Employee Stock Option or any participant in any
    Company Stock Plan or other Company benefit plan shall have any right
    thereunder to acquire any capital stock of the Company or the Surviving
    Corporation.

        (d) In this Agreement:

           "Company Employee Stock Option" means any option, whether or not then
       fully exercisable or vested, to purchase Company Common Stock granted
       under any Company Stock Plan.

           "Company Stock Plans" means the Company 1996 Stock Incentive Plan,
       the Company 1996 Non-Employee Director Stock Option Plan, the 1998 Howard
       S. Leight Stock Option Plan and the Bonus and Option Plan for CEO, COO
       and CFO of the Company for 2000.

    SECTION 6.05.  BENEFIT PLANS.  (a) From the Effective Time until
December 31, 2001, Parent shall either (i) maintain or cause the Surviving
Corporation (or in the case of a transfer of all or substantially all the assets
and business of the Surviving Corporation, its successors and assigns) to

                                      A-14
<Page>
maintain the Company benefit plans (other than plans providing for the issuance
of Company Common Stock or based on the value of Company Common Stock) at the
benefit levels in effect on the date of this Agreement or (ii) provide or cause
the Surviving Corporation (or, in such case, its successors or assigns) to
provide wages, salaries, bonuses and other benefits to employees of the Company
and the Company Subsidiaries that are at least equal to the current benefits
received by such employees.

        (b) From and after the Effective Time, Parent shall, and shall cause the
    Surviving Corporation to honor in accordance with their respective terms (as
    in effect on the date of this Agreement), all the Company's employment,
    bonus, commission, severance and termination agreements, plans and policies.

        (c) With respect to any "employee benefit plan", as defined in
    Section 3(3) of the Employee Retirement Income Security Act of 1974, as
    amended, maintained by Parent or any of its subsidiaries (including any
    severance plan), for all purposes, including determining eligibility to
    participate, level of benefits and vesting, service with the Company or any
    Company Subsidiary shall be treated as service with Parent or any of its
    subsidiaries; provided, however, that such service need not be recognized to
    the extent that such recognition would result in any duplication of
    benefits.

    SECTION 6.06.  INDEMNIFICATION, EXCULPATION AND INSURANCE.  (a) Parent and
Sub agree that all rights to indemnification, advancement of expenses and
exculpation from liabilities for acts or omissions occurring at or prior to the
Effective Time now existing in favor of the current or former directors or
officers of the Company and each Company Subsidiary as provided in their
respective certificates of incorporation or by-laws (or similar organizational
documents) shall be assumed by the Surviving Corporation, without further
action, at the Effective Time and shall survive the Merger and shall continue in
full force and effect in accordance with their terms. Parent shall cause the
Surviving Corporation to perform in a timely manner all of its obligations with
respect to such indemnification, advancement and rights, including, if
necessary, providing to the Surviving Corporation any funds necessary to ensure
that such obligations of the Surviving Corporation are satisfied.

        (b) In the event that Parent or the Surviving Corporation or any of
    their respective successors or assigns (i) consolidates with or merges into
    any other person and is not the continuing or surviving corporation or
    entity of such consolidation or merger or (ii) transfers or conveys all or
    substantially all its properties and assets to any person, then, and in each
    such case, Parent shall cause proper provision to be made so that the
    successor and assign of Parent or the Surviving Corporation, as the case may
    be, assumes the obligations set forth in this Section 6.06, and in such
    event all references to Parent or the Surviving Corporation, as the case may
    be, in this Section 6.06 shall be deemed a reference to such successor and
    assign.

        (c) For six years after the Effective Time, Parent shall maintain in
    effect the Company's current directors' and officers' liability insurance
    covering each person currently covered by the Company's directors' and
    officers' liability insurance policy for acts or omissions occurring prior
    to the Effective Time on terms with respect to such coverage and amounts no
    less favorable in any material respect to such directors and officers than
    those of such policy as in effect on the date of this Agreement; provided,
    however, that Parent may substitute therefor policies of a reputable
    insurance company the material terms of which, including coverage and
    amount, are no less favorable in any material respect to such directors and
    officers than the insurance coverage otherwise required under this
    Section 6.06(c); provided, however, that in no event shall Parent be
    required to pay aggregate premiums for insurance under this Section 6.06(c)
    in excess of 200% of the amount of the aggregate premiums payable by the
    Company for 2001 for such purpose (which 2001 premiums are hereby
    represented and warranted by the Company to be $197,305); provided further,
    however, that Parent shall nevertheless be obligated to provide as much
    coverage as may be obtained for such 200% amount.

                                      A-15

connection with this Agreement, the Merger and the other transactions
contemplated hereby shall be paid in accordance with the provisions of the
Master Agreement (as defined in Section 7.01(c)); provided, however, that the
Company shall be responsible for the reasonable costs and expenses of the
Oversight Committee (including reasonable costs and expenses of its legal
counsel and financial advisors).

    SECTION 6.08.  PUBLIC ANNOUNCEMENTS.  None of Parent, Sub or the Company
shall issue any press release or make any other public statements with respect
to the Merger or any other transaction contemplated hereby other than in
accordance with the Master Agreement, except as may be required by applicable
law, court process or by obligations pursuant to any listing agreement with any
national securities exchange.

documentary, stamp, recording and other similar taxes (including interest,
penalties and additions to any such taxes) ("Transfer Taxes") incurred in
connection with the transactions contemplated hereby shall be paid by either Sub
or the Surviving Corporation, and the Company shall cooperate with Sub and
Parent in preparing, executing and filing any tax returns with respect to such
Transfer Taxes.

Stockholder Approval:

        (a) by mutual written consent of Parent, Sub and the Company;

        (b) by either Parent or the Company:

           (i) if the Merger is not consummated on or before December 31, 2001

<Page>
       Section 8.01(b)(i) shall not be available to any party whose breach of
       this Agreement has been a principal reason the Merger has not been
       consummated by such date;

           (ii) if any Governmental Entity issues an order, decree or ruling or
       takes any other action permanently enjoining, restraining or otherwise
       prohibiting the Merger and such order, decree, ruling or other action

        (c) by Parent, if the Company breaches or fails to perform in any
    material respect any of its representations, warranties or covenants
    (including Section 5.02) contained in this Agreement, which breach or
    failure to perform (other than a breach of Section 5.02) (i) would give rise
    to the failure of a condition set forth in Section 7.02(a) or 7.02(b), and
    (ii) cannot be or has not been cured within 30 days after the giving of
    written notice to the Company of such breach.

    SECTION 8.02.  EFFECT OF TERMINATION.  In the event of termination of this
Agreement by either the Company or Parent as provided in Section 8.01, this
Agreement shall forthwith become void and have no effect, without any liability
or obligation on the part of Parent, Sub or the Company, other than the last
sentence of Section 6.02, Section 6.07, this Section 8.02 and Article IX, which

warranty or covenant set forth in this Agreement.

    SECTION 8.03.  AMENDMENT.  This Agreement may be amended by the parties at
any time before or after receipt of the Company Stockholder Approval; provided,
however, that after receipt of the Company Stockholder Approval, there shall be

extension or waiver shall be valid only if set forth in an instrument in writing
signed on behalf of such party. The failure of any party to this Agreement to
assert any of its rights under this Agreement or otherwise shall not constitute
a waiver of such rights.

May 25, 2001

Oversight Committee of the Board of Directors
Bacou USA, Inc.
10 Thurber Boulevard
Smithfield, RI 02917

Members of the Oversight Committee:

    We understand that Bacou USA, Inc., a Delaware corporation (the "Company")
and a majority-owned subsidiary of Bacou SA, a French societe anonyme (the
"Principal Company Stockholder"), is considering a transaction (the "U.S.
Transaction") whereby Christian Dalloz SA, a French societe anonyme ("Parent"),
will acquire the Principal Company Stockholder and the Company. Pursuant to the
terms of an Agreement and Plan of Merger, to be dated as of May 29, 2001 (the
"Merger Agreement"), to be entered into by and among the Company, Parent and
Daniel U. S. Sub, Inc., a Delaware corporation ("Merger Subsidiary") and a
wholly owned subsidiary of Parent, among other things, (i) Merger Subsidiary
will be merged with and into the Company (the "Merger"), and (ii) in connection
with the Merger, each issued and outstanding share of common stock, par value
$.001 per share (the "Common Stock"), of the Company (other than shares of
Common Stock owned by the Principal Company Stockholder and Appraisal Shares (as
defined in the Merger Agreement)) will be converted into the right to receive
$28.50 in cash (the "Merger Consideration"). The shares of Common Stock owned by
the Principal Company Stockholder will not be converted and will not be
otherwise affected by the Merger and will remain outstanding. We further
understand that, pursuant to the terms of the Master Agreement (as defined in
the Merger Agreement), among other things, the Principal Company Stockholder
will become a wholly owned subsidiary of Parent through a series of stock
purchases and related transactions and, in connection therewith, the
shareholders of the Principal Company Stockholder will receive cash and shares
of Parent common equity (the "French Transactions" and, together with the U.S.
Transaction, the "Transactions"), and that consummation of the U.S. Transaction
is conditioned upon, among other things, all of the conditions precedent to the
consummation of the French Transactions (other than the Merger) having been
satisfied or waived in accordance with the Master Agreement. The terms and
conditions of the Transactions are more fully set forth in the Merger Agreement
and the Master Agreement.

    You have requested our opinion as to the fairness from a financial point of
view to the holders of shares of Common Stock (other than the Principal Company
Stockholder) of the Merger Consideration to be received by such holders in the
Merger.

    UBS Warburg LLC ("UBS Warburg") has acted as financial advisor to the
Oversight Committee of the Board of Directors of the Company in connection with
the U.S. Transaction. UBS Warburg will receive a fee from the Company in
connection with the rendering of this opinion. In the ordinary course of
business, UBS Warburg, its successors and affiliates may trade or have traded
securities of the Company, the Principal Company Stockholder and/or Parent for
their own accounts and, accordingly, may at any time hold a long or short
position in such securities. As of February 13, 2001, an affiliate of UBS
Warburg held a long position of approximately 930,496 shares of Common Stock.

    Our opinion does not address the Company's underlying business decision to
effect the Transactions or the Merger or constitute a recommendation to any
shareholder of the Company as to how such shareholder should vote with respect
to the Merger Agreement or any other matter. We have not been asked to, nor do
we, at your direction, offer any opinion as to the material terms of the Merger
Agreement or the Master Agreement or the form of the Transactions contemplated
thereby. In rendering this opinion, we have assumed, with your consent, that the
final executed forms of the Merger Agreement and the Master Agreement do not
differ in any material respect from the respective drafts that we have examined,
that the Company, Merger Subsidiary and Parent will comply with all the material
terms of the Merger Agreement, and that the parties thereto will comply with all
the material terms of the Master Agreement. Although we have not been authorized
to and have not solicited indications of interest from any party with respect to
a business combination with the Company, we understand that the Principal
Company Stockholder's financial advisor solicited indications of interest from
third parties with respect to a business combination with the Principal Company
Stockholder and the Company.

    In arriving at our opinion, we have, among other things: (i) reviewed
certain publicly available business and historical financial information
relating to the Company, (ii) reviewed the reported prices and trading activity
for the Common Stock, (iii) reviewed certain internal financial information and
other data relating to the business and financial prospects of the Company,
including estimates and financial forecasts prepared by management of the
Company, that were provided to us by the Company in September 2000 and not
publicly available, (iv) reviewed certain historical pro forma financial
information relating to the Principal Company Stockholder prepared by management
of the Principal Company Stockholder, that was provided to us by the Principal
Company Stockholder and not publicly available, (v) conducted discussions with
members of the senior management of the Company, (vi) reviewed publicly
available financial and stock market data with respect to certain other
companies in lines of business we believe to be generally comparable to those of
the Company, (vii) compared the financial terms of the U.S. Transaction with the
publicly available financial terms of certain other transactions which we
believe to be generally relevant, (viii) reviewed drafts of the Merger Agreement
and the Master Agreement, and (ix) conducted such other financial studies,
analyses, and investigations, and considered such other information as we deemed
necessary or appropriate.

    In preparing the financial and comparative analyses in connection with the
rendering of this opinion, we were not provided by the Company with current
financial forecasts as to the business and financial prospects of the Company,
as prepared by the Company's management. Accordingly, at the direction of the
Oversight Committee, in reaching this opinion, we have not taken into
consideration any forecasts of the Company's future business or financial
performance prepared by the Company's management.

    In addition, in connection with our review, at your direction, we have not
assumed any responsibility for independent verification of any of the
information reviewed by us for the purpose of this opinion and have, at your
direction, relied on its being complete and accurate in all material respects.
In addition, at your direction, we have not made any independent evaluation or
appraisal of any of the assets or liabilities (contingent or otherwise) of the
Company, nor have we been furnished with any such evaluation or appraisal. Our
opinion is necessarily based on economic, monetary, market and other conditions
as in effect on, and the information made available to us as of, the date
hereof.

    Based upon and subject to the foregoing, it is our opinion that, as of the
date hereof, the Merger Consideration to be received by the holders of shares of
Common Stock (other than the Principal Company Stockholder) in the Merger is
fair from a financial point of view to such holders.

                               Very truly yours,
                                UBS WARBURG LLC

                          SECTION 262 OF THE DELAWARE
                            GENERAL CORPORATION LAW

    APPRAISAL RIGHTS.--(a) Any stockholder of a corporation of this State who
holds shares of stock on the date of the making of a demand pursuant to
subsection (d) of this section with respect to such shares, who continuously
holds such shares through the effective date of the merger or consolidation, who
has otherwise complied with subsection (d) of this section and who has neither
voted in favor of the merger or consolidation nor consented thereto in writing
pursuant to Section 228 of this title shall be entitled to an appraisal by the
Court of Chancery of the fair value of the stockholder's shares of stock under
the circumstances described in subsections (b) and (c) of this section. As used
in this section, the word "stockholder" means a holder of record of stock in a
stock corporation and also a member of record of a nonstock corporation; the
words "stock" and "share" mean and include what is ordinarily meant by those
words and also membership or membership interest of a member of a nonstock
corporation; and the words "depository receipt" mean a receipt or other
instrument issued by a depository representing an interest in one or more shares
or fractions thereof, solely of stock of a corporation, which stock is deposited
with the depository.

    (b) Appraisal rights shall be available for the shares of any class or
series of stock of a constituent corporation in a merger or consolidation to be
effected pursuant to Section 251 (other than a merger effected pursuant to
Section 251(g) of this title), Section 252, Section 254, Section 257,
Section 258, Section 263 or Section 264 of this title:

        (1) Provided, however, that no appraisal rights under this section shall
    be available for the shares of any class or series of stock, which stock, or
    depository receipts in respect thereof, at the record date fixed to
    determine the stockholders entitled to receive notice of and to vote at the
    meeting of stockholders to act upon the agreement of merger or
    consolidation, were either (i) listed on a national securities exchange or
    designated as a national market system security on an interdealer quotation
    system by the National Association of Securities Dealers, Inc. or (ii) held
    of record by more than 2,000 holders; and further provided that no appraisal
    rights shall be available for any shares of stock of the constituent
    corporation surviving a merger if the merger did not require for its
    approval the vote of the stockholders of the surviving corporation as
    provided in subsection (f) of Section 251 of this title.

        (2) Notwithstanding paragraph (1) of this subsection, appraisal rights
    under this section shall be available for the shares of any class or series
    of stock of a constituent corporation if the holders thereof are required by
    the terms of an agreement of merger or consolidation pursuant to Section
    Section 251, 252, 254, 257, 258, 263 and 264 of this title to accept for
    such stock anything except:

           (a) Shares of stock of the corporation surviving or resulting from
       such merger or consolidation, or depository receipts in respect thereof;

           (b) Shares of stock of any other corporation, or depository receipts
       in respect thereof, which shares of stock (or depository receipts in
       respect thereof) or depository receipts at the effective date of the
       merger or consolidation will be either listed on a national securities
       exchange or designated as a national market system security on an
       interdealer quotation system by the National Association of Securities
       Dealers, Inc. or held of record by more than 2,000 holders;

           (c) Cash in lieu of fractional shares or fractional depository
       receipts described in the foregoing subparagraphs a. and b. of this
       paragraph; or

                                      C-1
<Page>
           (d) Any combination of the shares of stock, depository receipts and
       cash in lieu of fractional shares or fractional depository receipts
       described in the foregoing subparagraphs a., b. and c. of this paragraph.

        (3) In the event all of the stock of a subsidiary Delaware corporation
    party to a merger effected under Section 253 of this title is not owned by
    the parent corporation immediately prior to the merger, appraisal rights
    shall be available for the shares of the subsidiary Delaware corporation.

    (c) Any corporation may provide in its certificate of incorporation that
appraisal rights under this section shall be available for the shares of any
class or series of its stock as a result of an amendment to its certificate of
incorporation, any merger or consolidation in which the corporation is a
constituent corporation or the sale of all or substantially all of the assets of
the corporation. If the certificate of incorporation contains such a provision,
the procedures of this section, including those set forth in subsections
(d) and (e) of this section, shall apply as nearly as is practicable.

    (d) Appraisal rights shall be perfected as follows:

        (1) If a proposed merger or consolidation for which appraisal rights are
    provided under this section is to be submitted for approval at a meeting of
    stockholders, the corporation, not less than 20 days prior to the meeting,
    shall notify each of its stockholders who was such on the record date for
    such meeting with respect to shares for which appraisal rights are available
    pursuant to subsections (b) or (c) hereof that appraisal rights are
    available for any or all of the shares of the constituent corporations, and
    shall include in such notice a copy of this section. Each stockholder
    electing to demand the appraisal of such stockholder's shares shall deliver
    to the corporation, before the taking of the vote on the merger or
    consolidation, a written demand for appraisal of such stockholder's shares.
    Such demand will be sufficient if it reasonably informs the corporation of
    the identity of the stockholder and that the stockholder intends thereby to
    demand the appraisal of such stockholder's shares. A proxy or vote against
    the merger or consolidation shall not constitute such a demand. A
    stockholder electing to take such action must do so by a separate written
    demand as herein provided. Within 10 days after the effective date of such
    merger or consolidation, the surviving or resulting corporation shall notify
    each stockholder of each constituent corporation who has complied with this
    subsection and has not voted in favor of or consented to the merger or
    consolidation of the date that the merger or consolidation has become
    effective; or

        (2) If the merger or consolidation was approved pursuant to Section 228
    or Section 253 of this title, each constituent corporation, either before
    the effective date of the merger or consolidation or within ten days
    thereafter, shall notify each of the holders of any class or series of stock
    of such constituent corporation who are entitled to appraisal rights of the
    approval of the merger or consolidation and that appraisal rights are
    available for any or all shares of such class or series of stock of such
    constituent corporation, and shall include in such notice a copy of this
    section; provided that, if the notice is given on or after the effective
    date of the merger or consolidation, such notice shall be given by the
    surviving or resulting corporation to all such holders of any class or
    series of stock of a constituent corporation that are entitled to appraisal
    rights. Such notice may, and, if given on or after the effective date of the
    merger or consolidation, shall, also notify such stockholders of the
    effective date of the merger or consolidation. Any stockholder entitled to
    appraisal rights may, within 20 days after the date of mailing of such
    notice, demand in writing from the surviving or resulting corporation the
    appraisal of such holders' shares. Such demand will be sufficient if it
    reasonably informs the corporation of the identity of the stockholder and
    that the stockholder intends thereby to demand the appraisal of such
    holder's shares. If such notice did not notify stockholders of the effective
    date of the merger or consolidation, either (i) each such constituent
    corporation shall send a second notice before the effective date of the
    merger or

                                      C-2
<Page>
    consolidation notifying each of the holders of any class series of stock of
    such constituent corporation that are entitled to appraisal rights of the
    effective date of the merger or consolidation or (ii) the surviving or
    resulting corporation shall send such a second notice to all such holders on
    or within 10 days after such effective date; provided, however, that if such
    second notice is sent more than 20 days following the sending of the first
    notice, such second notice need only be sent to each stockholder who is
    entitled to appraisal rights and who has demanded appraisal of such holder's
    shares in accordance with this subsection. An affidavit of the secretary or
    assistant secretary or of the transfer agent of the corporation that is
    required to give either notice that such notice has been given shall, in the
    absence of fraud, be prima facie evidence of the facts stated therein. For
    purposes of determining the stockholders entitled to receive either notice,
    each constituent corporation may fix, in advance, a record date that shall
    be not more than 10 days prior to the date the notice is given, provided,
    that if the notice is given on or after the effective date of the merger or
    consolidation, the record date shall be such effective date. If no record
    date is fixed and the notice is given prior to the effective date, the
    record date shall be the close of business on the day next preceding the day
    on which the notice is given.

    (e) Within 120 days after the effective date of the merger or consolidation,
the surviving or resulting corporation or any stockholder who has complied with
subsections (a) and (d) hereof and who is otherwise entitled to appraisal
rights, may file a petition in the Court of Chancery demanding a determination
of the value of the stock of all such stockholders. Notwithstanding the
foregoing, at any time within 60 days after the effective date of the merger or
consolidation, any stockholder shall have the right to withdraw such
stockholder's demand for appraisal and to accept the terms offered upon the
merger or consolidation. Within 120 days after the effective date of the merger
or consolidation, any stockholder who has complied with the requirements of
subsections (a) and (d) hereof, upon written request, shall be entitled to
receive from the corporation surviving the merger or resulting from the
consolidation a statement setting forth the aggregate number of shares not voted
in favor of the merger or consolidation and with respect to which demands for
appraisal have been received and the aggregate number of holders of such shares.
Such written statement shall be mailed to the stockholder within 10 days after
such stockholder's written request for such a statement is received by the
surviving or resulting corporation or within 10 days after expiration of the
period for delivery of demands for appraisal under subsection (d) hereof,
whichever is later.

    (f) Upon the filing of any such petition by a stockholder, service of a copy
thereof shall be made upon the surviving or resulting corporation, which shall
within 20 days after such service file in the office of the Register in Chancery
in which the petition was filed a duly verified list containing the names and
addresses of all stockholders who have demanded payment for their shares and
with whom agreements as to the value of their shares have not been reached by
the surviving or resulting corporation. If the petition shall be filed by the
surviving or resulting corporation, the petition shall be accompanied by such a
duly verified list. The Register in Chancery, if so ordered by the Court, shall
give notice of the time and place fixed for the hearing of such petition by
registered or certified mail to the surviving or resulting corporation and to
the stockholders shown on the list at the addresses therein stated. Such notice
shall also be given by 1 or more publications at least 1 week before the day of
the hearing, in a newspaper of general circulation published in the City of
Wilmington, Delaware or such publication as the Court deems advisable. The forms
of the notices by mail and by publication shall be approved by the Court, and
the costs thereof shall be borne by the surviving or resulting corporation.

    (g) At the hearing on such petition, the Court shall determine the
stockholders who have complied with this section and who have become entitled to
appraisal rights. The Court may require the stockholders who have demanded an
appraisal for their shares and who hold stock represented by certificates to
submit their certificates of stock to the Register in Chancery for notation
thereon of the pendency of the appraisal proceedings; and if any stockholder
fails to comply with such direction, the Court may dismiss the proceeding as to
such stockholder.

    (h) After determining the stockholders entitled to an appraisal, the Court
shall appraise the shares, determining their fair value exclusive of any element
of value arising from the accomplishment or expectation of the merger or
consolidation, together with a fair rate of interest, if any, to be paid upon
the amount determined to be the fair value. In determining such fair value, the
Court shall take into account all relevant factors. In determining the fair rate
of interest, the Court may consider all relevant factors, including the rate of
interest which the surviving or resulting corporation would have had to pay to
borrow money during the pendency of the proceeding. Upon application by the
surviving or resulting corporation or by any stockholder entitled to participate
in the appraisal proceeding, the Court may, in its discretion, permit discovery
or other pretrial proceedings and may proceed to trial upon the appraisal prior
to the final determination of the stockholder entitled to an appraisal. Any
stockholder whose name appears on the list filed by the surviving or resulting
corporation pursuant to subsection (f) of this section and who has submitted
such stockholder's certificates of stock to the Register in Chancery, if such is
required, may participate fully in all proceedings until it is finally
determined that such stockholder is not entitled to appraisal rights under this
section.

    (i) the Court shall direct the payment of the fair value of the shares,
together with interest, if any, by the surviving or resulting corporation to the
stockholders entitled thereto. Interest may be simple or compound, as the Court
may direct. Payment shall be so made to each such stockholder, in the case of
holders of uncertificated stock forthwith, and the case of holders of shares
represented by certificates upon the surrender to the corporation of the
certificates representing such stock. The Court's decree may be enforced as
other decrees in the Court of Chancery may be enforced, whether such surviving
or resulting corporation be a corporation of this State or of any state.

    (j) The costs of the proceeding may be determined by the Court and taxed
upon the parties as the Court deems equitable in the circumstances. Upon
application of a stockholder, the Court may order all or a portion of the
expenses incurred by any stockholder in connection with the appraisal
proceeding, including, without limitation, reasonable attorneys' fees and the
fees and expenses of experts, to be charged pro rata against the value of all of
the shares entitled to an appraisal.

    (k) From and after the effective date of the merger or consolidation, no
stockholder who has demanded appraisal rights as provided in subsection (d) of
this section shall be entitled to vote such stock for any purpose or to receive
payment of dividends or together distributions on the stock (except dividends or
other distributions payable to stockholders of record at a date which is prior
to the effective date of the merger or consolidation); provided, however; that
if no petition for an appraisal shall be filed within the time provided in
subsection (e) of this section, or if such stockholder shall deliver to the
surviving or resulting corporation a written withdrawal of such stockholder's
demand for an appraisal and an acceptance of the merger or consolidation, either
within 60 days after the effective date of the merger or consolidation as
provided in subsection (e) of this section or thereafter with the written
approval of the corporation, then the right of such stockholder to an appraisal
shall cease. Notwithstanding the foregoing, no appraisal proceeding in the Court
of Chancery shall be dismissed as to any stockholder without the approval of the
Court, and such approval may be conditioned upon such terms as the Court deems
just.

    (l) The shares of the surviving or resulting corporation to which the shares
of such objecting stockholders would have been converted had they assented to
the merger or consolidation shall have the status of authorized and unissued
shares of the surviving or resulting corporation. (last amended by Ch. 339,
L. '98. Eff. 7-1-98.)
