                                               AGREEMENT AND PLAN OF MERGER
                                     dated as of October 26, 2001 (the
                                     "AGREEMENT"), by and among DJ ORTHOPEDICS,
                                     INC., a Delaware corporation (the
                                     "PARENT"), DJ ACQUISITION CORPORATION, a
                                     Delaware corporation and a wholly owned
                                     subsidiary of the Parent (the "MERGER
                                     SUBSIDIARY") and DONJOY, L.L.C., a Delaware
                                     limited liability company (the "COMPANY").

         The Parent has filed a registration statement with the Securities and
Exchange Commission pursuant to the Securities Act of 1933, as amended (the
"SECURITIES ACT"), relating to the initial public offering of shares of its
common stock, $.01 par value per share (the "PARENT COMMON STOCK") (such
offering, the "PARENT IPO"). In order to facilitate the Parent IPO, the parties
hereto desire to enter into the transactions contemplated hereby.

         The board of directors or board of managers, as applicable, of each of
the Parent, the Merger Subsidiary and the Company, by resolutions duly adopted
pursuant to Sections 251 and 264 of the Delaware General Corporation Law (the
"DELAWARE STATUTE") and Section 18-209 of the Delaware Limited Liability Company
Act (the "LLC ACT") have approved this Agreement and the proposed merger of the
Merger Subsidiary with and into the Company in accordance with this Agreement.

         Pursuant to a Consent and Termination Agreement, dated as of the date
hereof, by and among the Company and the members of the Company named therein,
members of the Company holding more than 50% of each class of units of the
Company have approved this Agreement and the proposed merger of Merger
Subsidiary with and into the Company in accordance with this Agreement.

         For Federal income tax purposes, the Parent IPO and the Merger (as
defined below) are intended to be treated, in conjunction, as a contribution of
cash and Common Units and Preferred Units (each as defined below) in exchange
for Parent Common Stock (as defined below) and cash under Section 351 of the
Internal Revenue Code of 1986, as amended.

         ACCORDINGLY, in consideration of the mutual benefits to be derived from
this Agreement, the parties hereto agree as follows:

                                    ARTICLE I

                                     GENERAL

1.1      THE MERGER.

         At the Effective Time (as defined in SECTION 1.2) and in accordance
with the provisions of this Agreement, the Merger Subsidiary shall be merged
(the "MERGER") with and into the Company, which shall be the surviving entity of
the Merger (the "SURVIVING ENTITY", and the Company and the Merger Subsidiary
collectively, the "CONSTITUENT ENTITIES"). The name of the Company shall be
adopted by the Surviving Entity and shall remain unchanged by the Merger.

1.2      THE EFFECTIVE TIME OF THE MERGER.

         The Merger shall become effective upon the filing by the Surviving
Entity of the certificate of merger attached hereto as ANNEX A (the "CERTIFICATE
OF MERGER") with the Secretary of State of the State of Delaware pursuant to
Sections 103 and 264(c) of the Delaware Statute and Section 18-209(c) of the LLC
Act; PROVIDED, HOWEVER, that in no event shall the Certificate of Merger be
filed until immediately prior to the consummation of the Parent IPO. The
Certificate of Merger shall be executed and delivered in the manner provided
under the Delaware Statute and the LLC Act. The date and time when the Merger
shall become effective as aforesaid is herein called the "EFFECTIVE TIME."

1.3      EFFECT OF MERGER.

Time, the identity, existence, limited liability company organization, purposes,
powers, objects, franchises, privileges, rights and immunities of the Company
shall continue in effect and be unimpaired by the Merger, and the identity,
existence, corporate organization, purposes, powers, objects, franchises,
privileges, rights and immunities of the Merger Subsidiary shall be merged with
and into the Surviving Entity, which shall, as the Surviving Entity, be fully
vested therewith. At the Effective Time, the separate existence and corporate
organization of the Merger Subsidiary, except insofar as it may be continued by
statute, shall cease, and the Merger Subsidiary shall be merged with and into
the Surviving Entity.

                  (b) At the Effective Time, all rights, privileges, immunities
and franchises, of a public as well as of a private nature, of each of the
Constituent Entities, and all property, real, personal and mixed, tangible and
intangible (other than the Company Option Plan, the Company Options, the Company
Option Agreements, the Non-Employee Director Purchase Rights and the
Non-Employee Director Purchase Rights Agreements (each as defined in SECTION 2.1
below) which shall be assumed by the Parent pursuant to SECTION 2.1 and each of
the other documents listed on SCHEDULE 3.1 hereto which shall be assumed by the
Parent), in each case, of whatsoever kind or description, and all debts due on
whatever account and all other choses in action, and all and every other
interest, of or belonging to or due to any of the Constituent Entities, shall be
taken

                                       2
<Page>

and deemed to be transferred to and vested in the Surviving Entity without
further act or deed; and the title to any real estate, or any interest therein,
vested in any of the Constituent Entities shall not revert or be in any way
impaired by reason of the Merger; but the Surviving Entity shall thenceforth be
responsible and liable for all the liabilities, obligations and penalties of
each of the Constituent Entities, and any claim existing, or action or
proceeding, civil or criminal, pending by or against any of the Constituent
Entities, may be prosecuted as if the Merger had not taken place, or the
Surviving Entity may be substituted in its place, and any judgment rendered
against any of the Constituent Entities may be enforced against the Surviving
Entity. Neither the rights of creditors nor any liens upon the property of any
of the Constituent Entities shall be impaired by the Merger.

1.4      OPERATING AGREEMENT AND BY-LAWS OF SURVIVING ENTITY; DIRECTORS AND
OFFICERS.

         At the Effective Time, (a) the operating agreement attached hereto as
ANNEX B to this Agreement shall become the operating agreement of the Surviving
Entity until altered, amended or repealed as provided in said operating

become the by-laws of the Surviving Entity until altered, amended or repealed as
provided in said by-laws of the Surviving Entity, (c) the members of the board
of managers of the Company at the Effective Time shall become the members of the
board of managers of the Surviving Entity and (d) the officers of the Company at
the Effective Time shall become the officers of the Surviving Entity.

1.5      TAKING OF NECESSARY ACTION; FURTHER ASSURANCES.

         Prior to the Effective Time, the parties hereto shall take, or cause to
be taken (as the case may be), all such action as may be necessary or

                                   ARTICLE II

                       EFFECT OF MERGER ON EQUITY CAPITAL
                             OF CONSTITUENT ENTITIES

2.1      MERGER CONSIDERATION; EFFECT ON CAPITAL STOCK.

         The consideration for the Merger shall be as follows (the "MERGER
CONSIDERATION"):

                  (a) COMMON UNITS OF THE COMPANY. At the Effective Time, each
common unit of the Company (the "COMMON Units") issued and outstanding
immediately prior to the Effective Time (the "TERMINATING COMMON UNITS ") shall
automatically, by virtue of the Merger and without any action on the part of the
holder thereof, be converted into 10.812 shares (the "EXCHANGE RATIO") of Parent
Common Stock, with each holder of Terminating Common Units receiving that number
of shares of Parent Common Stock

                                       3
<Page>

and that amount of cash consideration in respect of fractional shares of Parent
Common Stock as set forth on SCHEDULE 2.1 hereof.

                  (b) PREFERRED UNITS OF THE COMPANY. At the Effective Time,
each preferred unit of the Company (the "PREFERRED UNITS") issued and
outstanding immediately prior to the Effective Time (the "TERMINATING PREFERRED
Units") shall automatically, by virtue of the Merger and without any action on
the part of the holder thereof, be converted into (i) shares of Parent Common
Stock at the Exchange Ratio and (ii) the right to receive a cash amount equal to
(A) $1,044.534917 PLUS (B) all accrued Preferred Return (as defined in the Third
Amended and Restated Operating Agreement of DonJoy, L.L.C., dated as of July 7,
2000, the "OPERATING AGREEMENT") on such Terminating Preferred Unit from and
including October 1, 2001 through, but not including, the date upon which the
Effective Time occurs LESS (C) the aggregate amount of all distributions made
pursuant to Section 6.3(a) of the Operating Agreement with respect to income
allocated to such Terminating Preferred Unit pursuant to clauses 2 and 3 of
Section 6.2(a)(iii)(A) of the Operating Agreement on or after October 1, 2001
through, but not including, the date upon which the Effective Time occurs
(collectively, the "PREFERRED LIQUIDATION AMOUNT"), with each holder of
Terminating Preferred Units receiving that number of shares of Parent Common
Stock and that amount of cash consideration as set forth on SCHEDULE 2.1 hereof.

                  (c) OPTIONS TO PURCHASE COMMON UNITS OF THE COMPANY.

                        (i) COMPANY OPTION PLAN.

                             (A) At the Effective Time, each option to purchase
         Common Units, whether vested or unvested, granted pursuant to the
         Company's Fourth Amended and Restated 1999 Option Plan (the "COMPANY
         OPTION PLAN") issued and outstanding immediately prior to the Effective
         Time (the "COMPANY OPTIONS") shall be deemed to constitute an option to
         acquire, on the same terms and conditions as set forth in the existing
         option agreement between the optionholder and the Company (except as
         set forth below), the same number of shares of Parent Common Stock as
         the holder of such Company Option would have been entitled to receive
         pursuant to the Merger had such holder exercised such Company Option in
         full immediately prior to the Effective Time.

                              (B) At the Effective Time, the Parent shall assume
         the Company Option Plan, each Company Option in accordance with the
         terms under which it was issued and each option agreement by which such
         Company Option is evidenced (each, a "COMPANY OPTION AGREEMENT");
         PROVIDED, HOWEVER, that (i) the terms and conditions of the Company
         Option Plan, each Company Option and each Company Option Agreement
         shall be revised to the extent necessary to reflect changes from a
         limited liability company to corporate form and (ii) the exercise price
         for each Company Option, as reflected in the corresponding Company
         Option Agreement, will be proportionately adjusted to reflect the
         change from Common Units to Parent Common Stock at the Exchange Ratio.
         As promptly as practicable after the Effective Time, the Parent shall
         enter into

                                       4
<Page>

         revised Company Option Agreements with each holder of Company Options
         to effectuate the provisions of the immediately preceding sentence. At
         or prior to the Effective Time, the Parent shall take all corporate
         action necessary to reserve for issuance a sufficient number of shares
         of Parent Common Stock as shall be required for delivery upon exercise
         of the Company Options assumed by it in accordance with this SECTION
         2.1(C)(I).

                        (ii) NON-EMPLOYEE DIRECTOR PURCHASE RIGHTS.

                              (A) At the Effective Time, each right to purchase
         Common Units granted pursuant to the Non-Employee Director Purchase
         Rights Agreements, by and between the Company and each of Kirby L.
         Cramer and Ivan R. Sabel (collectively, the "NON-EMPLOYEE DIRECTOR
         PURCHASE RIGHTS AGREEMENTS") shall be deemed to constitute a right to
         acquire (collectively, the "NON-EMPLOYEE DIRECTOR PURCHASE RIGHTS"), on
         the same terms and conditions as set forth in the Non-Employee Director
         Purchase Rights Agreements (except as set forth below), the same number
         of shares of Parent Common Stock as the holder of such Non-Employee
         Director Purchase Rights would have been entitled to receive pursuant
         to the Merger had such holder exercised such Non-Employee Director
         Purchase Rights in full immediately prior to the Effective Time.

                              (B) At the Effective Time, the Parent shall assume
         each Non-Employee Director Purchase Rights Agreement and each
         Non-Employee Director Purchase Rights in accordance with such
         Non-Employee Director Purchase Rights Agreement; PROVIDED, HOWEVER,
         that the terms and conditions of each Non-Employee Director Purchase
         Right and each Non-Employee Director Purchase Rights Agreement shall be
         revised to the extent necessary to reflect changes from a limited
         liability company to corporate form. As promptly as practicable after
         the Effective Time, the Parent shall enter into revised Non-Employee
         Director Purchase Rights Agreements with each holder of Non-Employee
         Director Purchase Rights to effectuate the provisions of the
         immediately preceding sentence. At or prior to the Effective Time, the
         Parent shall take all corporate action necessary to reserve for
         issuance a sufficient number of shares of Parent Common Stock as shall
         be required for delivery upon exercise of the Non-Employee Director
         Purchase Rights assumed by it in accordance with this SECTION
         2.1(c)(ii).

                  (d) COMMON STOCK OF MERGER SUBSIDIARY. At the Effective Time,
each share of common stock, $0.01 par value per share, of the Merger Subsidiary
issued and outstanding immediately prior to the Effective Time shall
automatically, by virtue of the Merger and without any action on the part of the
holder thereof, be cancelled and no consideration shall be delivered therefor.

                  (d) FRACTIONAL SHARES. No fractional shares of Parent Common
Stock or scrip shall be issued upon conversion of the Terminating Common Units
or the Terminating Preferred Units pursuant to SECTIONS 2.1(a) and 2.1(b). The
number of full shares of Parent Common Stock issuable to a holder upon
conversion of the Terminating

                                       5
<Page>

Common Units or the Terminating Preferred Units of such holder shall be computed
on the basis of the aggregate number of Terminating Common Units or Terminating
Preferred Units to be converted by such holder. Instead of any fractional shares
of Parent Common Stock which would otherwise be issuable upon conversion of any
shares of Terminating Common Units or Terminating Preferred Units, the Parent
shall pay a cash adjustment in respect of such fractional interest in an amount
equal to the product of (i) initial public offering price of Parent Common Stock
in the Parent IPO as set forth in the final prospectus for the Parent IPO and
(ii) such fractional interest. The holders of fractional interests shall not be
entitled to any rights as stockholders of the Parent in respect of such
fractional interests.

                                  ARTICLE III

of this Agreement shall be governed by, and construed and enforced in accordance
with, the domestic laws of the State of Delaware, without giving effect to any
choice or conflict of law provision or rule (whether in the State of Delaware or
any other jurisdiction) that would cause the application of the laws of any
jurisdiction other than the State of Delaware. In furtherance of the foregoing,
the internal law of the State of Delaware will control the interpretation and
construction of this Agreement, even if under such jurisdiction's choice of law
or conflict of law analysis, the substantive law of some other jurisdiction

         All the terms and provisions of this Agreement shall be binding upon,
and inure to the benefit of, the parties hereto and their respective successors

         It is the desire and intent of the parties that the provisions of this
Agreement be enforced to the fullest extent permissible under the law and public
policies applied in each jurisdiction in which enforcement is sought.
Accordingly, in the event that any provision of this Agreement would be held in
any jurisdiction to be invalid, prohibited or unenforceable for any reason, such
provision, as to such jurisdiction, shall be ineffective, without invalidating
the remaining provisions of this Agreement or affecting the validity or
enforceability of such provision in any jurisdiction. Notwithstanding the
foregoing, if such provision could be more narrowly drawn so as not be invalid,
prohibited or unenforceable in such jurisdiction, it shall, as to such
jurisdiction, be so narrowly drawn, without invalidating the remaining
provisions of this Agreement or affecting the validity or enforceability of such
provision in any other jurisdiction.

the absence of a designation by the Board). The Board may, in its sole
discretion, determine that the meeting shall not be held at any place, but may
instead be held solely by means of remote communication as provided in Section
2.13.

                                       20

2.2      ANNUAL MEETINGS.

                  Annual meetings of the stockholders, commencing with the year
2002, shall be held for the election of directors and for the transaction of
such other business as may properly come before the meeting.

2.3      SPECIAL MEETINGS.

                  Special meetings of the stockholders for any purpose or
purposes may be called by the Board, or the Chairman of the Board, the Chief
Executive Officer or the President and may not be called by any other person.
Notwithstanding the foregoing, whenever holders of one or more classes or series
of Preferred Stock shall have the right, voting separately as a class or series,
to elect directors, such holders may call special meetings of such holders
pursuant to the terms of the certificate of designation for such classes or
series.

2.4      NOTICE OF MEETINGS AND ADJOURNED MEETINGS; WAIVERS OF NOTICE.

                  (a) Except as otherwise provided by the General Corporation
Law of the State of Delaware as the same exists or may hereafter be amended
("DELAWARE LAW"), the Amended and Restated Certificate of Incorporation of the
Corporation approved by the Board and stockholders of the Corporation in
connection with the Corporation's initial public offering of shares of its
Common Stock and filed with the Secretary of State of the State of Delaware on
November 19, 2001, as the same may be amended from time to time, (the
"CERTIFICATE") or these By-laws, notice of each annual or special meeting of the
stockholders shall be given to each stockholder of record entitled to vote at
such meeting not less than 10 nor more than 60 days before the day on which the
meeting is to be held, by delivering written notice thereof to such stockholder
personally, or by mailing a copy of such notice, postage prepaid, directly to
the stockholder at such stockholder's address as it appears in the records of
the Corporation, or by transmitting such notice thereof at such address by
telegraph, cable or other telephonic transmission, or by electronic transmission
consented to by the stockholder to whom the bnotice is given in accordance with
the requirements of Delaware Law which consent has not been revoked as provided
in Delaware Law. Every such notice shall state the place, if any, the date and
hour of the meeting, the means of remote communications, if any, by which
stockholders and proxy holders may be deemed to be present in person and vote at
such meeting and, in case of a special meeting, the purpose or purposes for
which the meeting is called. Unless these By-laws otherwise require, when a
meeting is adjourned to another time or place (whether or not a quorum is
present), notice need not be given of the adjourned meeting if the time, place,
if any, thereof and the means of remote communications, if any, by which
stockholders and proxy holders may be deemed to be present in person and vote at
any such adjourned meeting are announced at the meeting at which the adjournment
is taken. At the adjourned meeting, the Corporation may transact any business
which might have been transacted at the original meeting. Notwithstanding the
foregoing, if the adjournment is for more than 30 days, or if after the
adjournment a new record date is fixed for the adjourned meeting, a notice of
the adjourned meeting shall be given to each stockholder of record entitled to
vote at the meeting not less than 10 nor more than 60 days before the day on
which the meeting is to be held.

                                       21
<Page>

                  (b) A written waiver of any such notice signed by the person
entitled thereto, or a waiver by electronic transmission by the person entitled
to notice, whether before or after the time stated therein, shall be deemed
equivalent to notice. Attendance of a person at a meeting shall constitute a
waiver of notice of such meeting, except when the person attends the meeting for
the express purpose of objecting, at the beginning of the meeting, to the
transaction of any business because the meeting is not lawfully called or
convened. Except as otherwise provided in these By-laws, neither the business to
be transacted at, nor the purpose of, any meeting of the stockholders need be
specified in any such notice or waiver of notice, whether in writing or by
electronic transmission. Business transacted at any special meeting of
stockholders shall be limited to the purposes stated in the notice.

2.5      QUORUM.

                  Unless otherwise provided by the Certificate or these By-laws
and subject to Delaware Law, at each meeting of stockholders the holders of a
majority of the issued and outstanding shares of capital stock of the
Corporation entitled to vote at such meeting, present in person or represented
by proxy, shall constitute a quorum for the transaction of business.

2.6      ORGANIZATION.

                  Unless otherwise determined by the Board, at each meeting of
the stockholders, the Chairman of the Board, if one shall have been elected, (or
in his absence or if one shall not have been elected, the Chief Executive
Officer, or in his absence or if one shall not have been elected, the President,
if he or she is also a director) shall act as chairman of the meeting. The
Secretary (or in his absence or inability to act, the person whom the chairman
of the meeting shall appoint secretary of the meeting) shall act as secretary of
the meeting and keep the minutes thereof.

2.7      ORDER OF BUSINESS.

                  The order of business at each meeting of the stockholders
shall be determined by the chairman of such meeting.

2.8      VOTING.

                  (a) Unless otherwise provided in the Certificate and subject
to Delaware Law, each stockholder shall be entitled to one vote in person or by
proxy for each outstanding share of capital stock of the Corporation held by
such stockholder. Any shares of capital stock of the Corporation held by the
Corporation shall have no voting rights. Persons holding stock in a fiduciary
capacity shall be entitled to vote the shares so held. A person whose stock is
pledged shall be entitled to vote, unless in the transfer by the pledgor on the
books of the Corporation, such person has expressly empowered the pledgee to
vote thereon, in which case only the pledgee or such pledgee's proxy may
represent such stock and vote thereon. If shares or other securities having
voting power stand of record in the names of two or more persons, whether
fiduciaries, members of a partnership, joint tenants, tenants in common, tenants
by the entirety or otherwise, or if two or more persons have the same fiduciary
relationship respecting the same shares, unless the Secretary of the Corporation
shall be given written notice to the contrary and

                                       22
<Page>

furnished with a copy of the instrument or order appointing them or creating the
relationship wherein it is so provided, their acts with respect to voting shall
have the following effect:

                  (i) if only one votes, such person's act binds all;

                  (ii) if more than one votes, the act of the majority so voting
         binds all; and

                  (iii) if more than one votes, but the vote is evenly split on
         any particular matter, such shares shall be voted in the manner
         provided by Delaware Law.

If the instrument so filed shows that any such tenancy is held in unequal
interests, a majority or even-split for the purposes of this Section 2.8 shall
be a majority or even-split in interest. The Corporation shall not vote directly
or indirectly any share of its own capital stock.

                  (b) Unless otherwise provided in Delaware Law, the Certificate
or these By-laws, in all matters other than the election of directors, the
affirmative vote of a majority of the outstanding shares of capital stock of the
Corporation present, in person or by proxy, at a meeting of stockholders and
entitled to vote on the subject matter shall constitute the valid act of the
stockholders. Directors shall be elected by a plurality of the votes of the
shares present in person or by proxy at the meeting and entitled to vote on the
election of directors.

                  (c) The election of directors need not be by written ballot.
However, if authorized by the Board, the use of a written ballot shall be
satisfied by a ballot submitted by electronic transmission, provided that any
such electronic transmission must either set forth or be submitted with
information from which it can be determined that the electronic transmission was
authorized by the stockholder or proxyholder.

                  (d) Each stockholder entitled to vote at a meeting of
stockholders may authorize another person or persons to act for such stockholder
by proxy, but no such proxy shall be voted or acted upon after three years from
its date, unless the proxy provides for a longer period.

                  (e) Without limiting the manner in which a stockholder may
authorize another person or persons to act for such stockholder as proxy
pursuant to subsection (d) of this Section 2.8, the following shall constitute a
valid means by which a stockholder may grant such authority:

                  (i) A stockholder may execute a writing authorizing another
         person or persons to act for such stockholder as proxy. Execution may
         be accomplished by the stockholder or such stockholder's authorized
         officer, director, employee or agent signing such writing or causing
         such person's signature to be affixed to such writing by any reasonable
         means including, but not limited to, by facsimile signature; and

                  (ii) A stockholder may authorize another person or persons to
         act for such stockholder as proxy by transmitting or authorizing the
         transmission of a telegram, cablegram, or other means of electronic
         transmission to the person who will be the holder of the proxy or to a
         proxy solicitation firm, proxy support service organization or like
         agent duly authorized by the person who will be the holder of the proxy
         to receive such transmission, provided that any such telegram,
         cablegram or other means of electronic

                                       23
<Page>

         transmission must either set forth or be submitted with information
         from which it can be determined that the telegram, cablegram or other
         electronic transmission was authorized by the stockholder. If it is
         determined that such telegrams, cablegrams or other electronic
         transmissions are valid, the inspectors or, if there are no inspectors,
         such other persons making that determination shall specify the
         information upon which they relied.

                  (f) Any copy, facsimile telecommunication or other reliable
reproduction of the writing or transmission created pursuant to subsection (e)
of this Section 2.8 may be substituted or used in lieu of the original writing
or transmission for any and all purposes for which the original writing or
transmission could be used, provided that such copy, facsimile telecommunication
or other reproduction shall be a complete reproduction of the entire original
writing or transmission.

2.9      INSPECTORS OF ELECTIONS.

                  Preceding any meeting of the stockholders, the Board by
resolution or the Chairman of the Board or the Chief Executive Officer shall
appoint one or more persons to act as inspectors at the meeting and make a
written report thereof. The Corporation may designate one or more alternate
inspectors to replace any inspector who fails to act. In the event no inspector
or alternate is able to act at a meeting of stockholders, the person presiding
at the meeting shall appoint one or more inspectors to act at the meeting. Each
inspector, before entering upon the discharge of the duties of an inspector,
shall take and sign an oath faithfully to execute the duties of inspector with
strict impartiality and according to the best of such inspector's ability. The
inspectors shall:

         (a) ascertain the number of shares outstanding and the voting power of
each;

         (b) determine the shares represented at a meeting and the validity of
proxies and ballots; (c) count all votes and ballots;

         (d) determine and retain for a reasonable period a record of the
disposition of any challenges made to any determination by the inspectors; and

         (e) certify their determination of the number of shares represented at
the meeting, and his or her count of all votes and ballots.

                  The inspector(s) may appoint or retain other persons or
entities to assist the inspectors in the performance of the duties of inspector.

                  In determining the shares represented and the validity and
counting of proxies and ballots, the inspector shall be limited to an
examination of the proxies, any envelopes submitted with those proxies, any
information provided in accordance with Section 2.8 of these By-laws or any
information provided pursuant to Section 2.13(b)(i) and (iii) of these By-laws,
ballots and the regular books and records of the Corporation. The inspector may
consider other reliable information for the limited purpose of reconciling
proxies and ballots submitted by or on behalf of banks, brokers or their
nominees or a similar person which represent more votes than the

                                       24
<Page>

holder of a proxy is authorized by the record owner to cast or more votes than
the stockholder holds of record. If the inspector considers other reliable
information for the limited purpose permitted by this paragraph, the inspector,
at the time of his or her certification pursuant to subsection (e) of this
Section 2.9, shall specify the precise information considered, the person or
persons from whom the information was obtained, when this information was
obtained, the means by which the information was obtained, and the basis for the
inspector's belief that such information is accurate and reliable.

2.10     OPENING AND CLOSING OF POLLS.

                  The date and time of the opening and closing of the polls for
each matter to be voted upon at a stockholder meeting shall be announced at the
meeting. The inspector of the election shall be prohibited from accepting any
ballots, proxies or votes or any revocations thereof or changes thereto after
the closing of the polls, unless the Delaware Court of Chancery upon application
by a stockholder shall determine otherwise.

2.11     LIST OF STOCKHOLDERS.

                  It shall be the duty of the Secretary or other officer of the
Corporation who shall have charge of its stock ledger to prepare and make, at
least 10 days before every meeting of the stockholders, a complete list of the
stockholders entitled to vote thereat, arranged in alphabetical order, and
showing the address of each stockholder and the number of shares registered in
the name of each stockholder. Nothing contained in this Section 2.11 shall
require the Corporation to include electronic mail addresses or other electronic
contact information in such list. Such list shall be open to the examination of
any stockholder, for any purpose germane to any such meeting, for a period of at
least 10 days prior to such meeting (i) if so authorized by the Board, on a
reasonably accessible electronic network, provided that the information required
to gain electronic access to such list is provided with the notice of the
meeting, or (ii) during ordinary business hours, at the principal place of
business of the Corporation. If the Board determines to make the list available
on an electronic network, the Corporation shall take reasonable steps to ensure
that such information is available only to stockholders of the Corporation. If
the meeting is to be held at a place, then such list shall be produced and kept
at the time and place of the meeting during the whole time thereof, and may be
inspected by any stockholder who is present. If the meeting is to be held solely
by means of remote communications, then the list shall also be open to the
examination of any stockholder during the whole time of the meeting on a
reasonably accessible electronic network, and the information required to access
such list shall be provided with the notice of the meeting.

2.12     ACTION BY CONSENT.

                  Any action required or permitted to be taken at any annual or
special meeting of stockholders may be taken only upon the vote of stockholders
at an annual or special meeting duly noticed and called in accordance with
Delaware Law and may not be taken by written consent of stockholders without a
meeting.

                                       25
<Page>

2.13     PARTICIPATION AT STOCKHOLDER MEETINGS BY REMOTE COMMUNICATIONS

                  If authorized by the Board in its sole discretion, and subject
to such guidelines and procedures as the Board may adopt, stockholders and
proxyholders not physically present at a meeting of stockholders may, by means
of remote communication:

         (a) participate in a meeting of stockholders; and

         (b) be deemed present in person and vote at a meeting of stockholders
whether such meeting is to be held at a designated place or solely by remote
communication, provided that (i) the Corporation shall implement reasonable
measures to verify that each person deemed present and permitted to vote at the
meeting by means of remote communication is a stockholder or proxyholder, (ii)
the Corporation shall implement reasonable measures to provide such stockholders
and proxyholders a reasonable opportunity to participate in the meeting and to
vote on matters submitted to the stockholders, including an opportunity to read
or hear the proceedings of the meeting substantially concurrently with such
proceedings, and (iii) if any stockholder or proxyholder votes or takes other
action at the meeting by means of remote communication, a record of such vote or
other action shall be maintained by the Corporation.

2.14     NOMINATION OF DIRECTORS.

                  Only persons who are nominated in accordance with the
procedures set forth in these By-laws shall be eligible to serve as directors.
Nominations of persons for election to the Board of the Corporation may be made
at a meeting of stockholders (a) by or at the direction of the Board or (b) by
any stockholder of the Corporation who is a stockholder of record at the time of
giving of notice provided for in this Section 2.14, who shall be entitled to
vote for the election of directors at the meeting and who complies with the
notice procedures set forth in this Section 2.14. Such nominations, other than
those made by or at the direction of the Board, must be made pursuant to timely
notice in writing to the Secretary of the Corporation. To be timely, a
stockholder's notice shall be delivered to or mailed and received at the
principal executive offices of the Corporation not less than 90 days nor more
than 120 days prior to the first anniversary of the previous year's annual
meeting. Such stockholder's notice shall set forth (a) as to each person whom
the stockholder proposes to nominate for election or reelection as a director,
all information relating to such person that is required to be disclosed in
solicitations of proxies for election of directors, or which is otherwise
required, in each case pursuant to Regulation 14A under the Securities Exchange
Act of 1934, as amended (the "1934 Act") (including such person's written
consent to being named in the proxy statement as a nominee and to serving as a
director if elected); and (b) as to the stockholder giving the notice (i) the
name and address, as they appear on the Corporation's books, of such
stockholder, (ii) the class and number of shares of the Corporation which are
beneficially owned by such stockholder and (iii) a description of all
arrangements or understandings between such stockholder and each proposed
nominee and any other person or persons (including their names) pursuant to
which the nominations are to be made by such stockholder. At the request of the
Board, any person nominated by the Board for election as a director shall
furnish to the secretary of the Corporation that information required to be set
forth in a stockholder's notice of nomination which pertains to the nominee. No
person shall be eligible to serve as a director of the Corporation unless
nominated in accordance with the procedures set forth in this Section 2.14. The
chairman of the meeting shall, if the facts warrant,

                                       26
<Page>

determine and declare to the meeting that a nomination was not made in
accordance with the procedures prescribed by the By-laws, and if he should so
determine, he shall so declare to the meeting and the defective nomination shall
be disregarded. Notwithstanding the foregoing provisions of this Section 2.14, a
stockholder shall also comply with all applicable requirements of the 1934 Act,
and the rules and regulations thereunder with respect to the matters set forth
in this Section 2.14.

2.15     NOTICE OF BUSINESS.

                  At any meeting of the stockholders, only such business shall
be conducted as shall have been brought before the meeting (a) by or at the
direction of the Board or (b) by any stockholder of the Corporation who is a
stockholder of record at the time of giving of the notice provided for in this
Section 2.15, who shall be entitled to vote at such meeting and who complies
with the notice procedures set forth in this Section 2.15. For business to be
properly brought before a stockholder meeting by a stockholder, the stockholder
must have given timely notice thereof in writing to the Secretary of the
Corporation. To be timely, a stockholder's notice must be delivered to or mailed
and received at the principal executive offices of the Corporation not less than
90 days nor more than 120 days prior to the first anniversary of the previous
year's annual meeting. A stockholder's notice to the Secretary shall set forth
as to each matter the stockholder proposes to bring before the meeting (a) a
brief description of the business desired to be brought before the meeting and
the reasons for conducting such business at the meeting, (b) the name and
address, as they appear on the Corporation's books, of the stockholder proposing
such business, (c) the class and number of shares of the Corporation which are
beneficially owned by the stockholder and (d) any material interest of the
stockholder in such business business and a description of all arrangements or
understandings between such stockholder and any other person or persons
(including their names) in connection with the proposal of such business by such
stockholder. Notwithstanding anything in the By-laws to the contrary, no
business shall be conducted at a stockholder meeting except in accordance with
the procedures set forth in this Section 2.15. The chairman of the meeting
shall, if the facts warrant, determine and declare to the meeting that business
was not properly brought before the meeting and in accordance with the
provisions of the By-laws, and if he should so determine, he shall so declare to
the meeting that any such business not properly brought before the meeting shall
not be transacted. Notwithstanding the foregoing provisions of this Section
2.15, a stockholder shall also comply with all applicable requirements of the
1934 Act, and the rules and regulations thereunder with respect to the matters
set forth in this Section 2.15.

                                  ARTICLE III

                               BOARD OF DIRECTORS

3.1      GENERAL POWERS.

                  Except as otherwise provided by Delaware Law or the
Certificate, the business, property and affairs of the Corporation shall be
managed by or under the direction of the Board, which may exercise all such
powers of the Corporation and do all such lawful acts and things as are not by
law or by the Certificate directed or required to be exercised or done by the
stockholders.

                                       27
<Page>

3.2      NUMBER, CLASSES AND TERM OF OFFICE.

                  The Board shall consist of not less than three nor more than
fifteen directors, with the exact number of directors to be determined from time
to time solely by resolution adopted by the affirmative vote of a majority of
the entire Board. The directors shall be divided into three classes, designated
Class I, Class II and Class III. Each class shall consist, as nearly as may be
possible, of one-third of the total number of directors constituting the entire
Board. Except as otherwise provided in the Certificate, each director shall
serve for a term ending on the date of the third annual meeting of stockholders
next following the annual meeting at which such director was elected.
Notwithstanding the foregoing, each director shall hold office until such
director's successor shall have been duly elected and qualified or until such
director's earlier death, resignation or removal. Directors need not be
stockholders.

3.3      RESIGNATION.

                  Any director may resign at any time by a notice given in
writing or by electronic transmission to the Board or the Secretary of the
Corporation. Such resignation shall take effect at the time specified therein
or, if the time be not specified, upon receipt thereof; and unless otherwise
specified therein, the acceptance of such resignation shall not be necessary to
make it effective.

3.4      VACANCIES.

                  Unless otherwise provided in the Certificate, vacancies on the
Board resulting from death, resignation, removal or otherwise and newly created
directorships resulting from any increase in the number of directors may be
filled solely by a majority of the directors then in office (although less than
a quorum) or by the sole remaining director. Each director so elected shall hold
office for a term that shall coincide with the term of the Class to which such
director shall have been elected. If there are no directors in office, then an
election of directors may be held in accordance with Delaware Law. Unless
otherwise provided in the Certificate, when one or more directors shall resign
from the Board, effective at a future date, a majority of the directors then in
office, including those who have so resigned, shall have the power to fill such
vacancy or vacancies, the vote thereon to take effect when such resignation or
resignations shall become effective, and each director so chosen shall hold
office as provided in the filling of the other vacancies.

3.5      REMOVAL.

                  No director may be removed from office by the stockholders
except for cause and with the affirmative vote of the holders of not less than
66 2/3% of the total voting power of all outstanding securities of the
Corporation then entitled to vote generally in the election of directors, voting
together as a single class.

3.6      COMPENSATION.

                  Unless otherwise restricted by the Certificate or these
By-laws, the Board shall have authority to fix the compensation of directors,
including fees and reimbursement of expenses.

                                       28
<Page>

3.7      MEETINGS AND CONDUCT THEREOF

         (a) TIME AND PLACE OF MEETINGS. The Board may hold its meetings at such
place or places within or outside the State of Delaware, and at such times, as
may from time to time be determined by the Board (or the Chairman of the Board
in the absence of a determination by the Board).

         (b) ANNUAL MEETINGS. As soon as practicable after each annual meeting
of stockholders, the Board shall meet for the purpose of organization, the
election of officers and the transaction of other business, on the same day and
at the same place where such annual meeting shall be held unless it shall have
transacted all such business by written consent pursuant to Section 3.8 of this
Article III. Notice of such meeting need not be given. In the event such annual
meeting is not so held, the annual meeting of the Board may be held at such
place either within or outside the State of Delaware, on such date and at such
time as shall be specified in a notice thereof given as hereinafter provided in
Section 3.7(d) of this Article III or in a written waiver of notice thereof
signed by any director who chooses to waive the requirement of notice or a
waiver by electronic transmission by the director who chooses to waive the
requirement of notice.

         (c) REGULAR MEETINGS. After the place and time of regular meetings of
the Board shall have been determined and notice thereof shall have been once
given to each member of the Board, regular meetings may be held without further
notice being given.

         (d) SPECIAL MEETINGS. Special meetings of the Board may be called by
the Chairman of the Board and shall be called by the Chairman of the Board or
the Secretary on the written request of three directors. Notice of special
meetings of the Board shall be given to each director at least two days before
the date of the meeting in such manner as is determined by the Board or may be
given on such shorter notice as the person or persons calling such meeting may
deem necessary or appropriate under the circumstances.

         (e) WAIVER OF NOTICE. A written waiver of any notice signed by the
person entitled thereto, or a waiver by electronic transmission by the person
entitled to notice, whether before or after the time stated therein, shall be
deemed equivalent to notice. Attendance of a director at a meeting shall
constitute a waiver of notice of such meeting, except when such director attends
the meeting for the express purpose of objecting, at the beginning of the
meeting, to the transaction of any business because the meeting is not lawfully
called or convened. Except as otherwise provided in these By-laws, neither the
business to be transacted at, nor the purpose of, any meeting of directors need
be specified in any such notice or waiver of notice.

         (f) QUORUM AND MANNER OF ACTING. Unless the Certificate or these
By-laws require a greater number, a majority of the total number of directors
then in office shall be present in person at any meeting of the Board in order
to constitute a quorum for the transaction of business at such meeting, and the
affirmative vote of a majority of those directors present at any such meeting at
which a quorum is present shall be necessary for the passage of any resolution
or act of the Board. When a meeting is adjourned to another time or place
(whether or not a quorum is present), notice need not be given of the adjourned

                  Unless otherwise restricted by the Certificate or these

                  The Board may designate one or more committees, each committee
to consist of one or more of the directors of the Corporation. The Board may

authority of the Board of Directors in the management of the business and
affairs of the Corporation, and may authorize the seal of the Corporation to be
affixed to all papers

                                       30

which may require it, but no such committee shall have the power or authority in
reference to the following matter: (i) approving or adopting, or recommending to
the stockholders, any action or matter expressly required by Delaware Law to be

more of its directors or officers, or between the Corporation and any other
corporation, partnership, association, or other organization in which one or
more of its directors or officers are directors or officers, or have a financial
interest, shall be void or voidable solely for this reason, or solely because
the director or officer is present at or participates in the meeting of the
Board or committee thereof which authorizes the contract or transaction, or
solely because any such director's or officer's votes are counted for such
purpose if (i) the material facts as to the director's or officer's relationship
or interest and as to the contract or transaction are disclosed or are known to
the Board or the committee, and the Board or committee in good faith authorizes
the contract or transaction by the affirmative votes of a majority of the
disinterested directors, even though the disinterested directors be less than a
quorum; or (ii) the material facts as to the director's or officer's
relationship or interest and as to the contract or transaction are disclosed or
are known to the stockholders entitled to vote thereon, and the contract or
transaction is specifically approved in good faith by vote of the stockholders;
or (iii) the contract or transaction is fair as to the Corporation as of the
time it is authorized, approved or ratified, by the Board, a committee thereof
or the stockholders. Interested directors may be counted in determining the
presence of a quorum at a meeting of the Board or of a committee which
authorizes the contract or transaction.
